© 2017 Diabetes UK Aim: There is a high incidence of neonatal hypoglycaemia in neonates born to mothers with pre-existing diabetes. This often necessitates admission to the neonatal intensive care. Guidelines suggest maintaining intrapartum blood glucose levels (BGLs) of 4¿7 mmol/l in women with diabetes to reduce the risk of neonatal hypoglycaemia. This study assessed whether intrapartum BGLs in women with pre-gestational Type 1 and 2 diabetes were predictive of neonatal hypoglycaemia. Methods: A retrospective analysis of 261 births delivered at a tertiary hospital in Australia from 2009 to 2014. Results: There were 122 cases of neonatal hypoglycaemia (glucose = 2.6 mmol/l) in 261 births (47%). The mothers in the neonatal hypoglycaemia group spent less time with BGL in the range 4¿7 mmol/l [55 ± 37% vs. 65 ± 35%, P = 0.02; odds ratio (OR) 0.992, P = 0.03] and more time with BGL in the 7¿10 mmol/l range (31 ± 34% vs. 18 ± 27%, P = 0.003; OR 1.013, P = 0.003) compared with those without neonatal hypoglycaemia. Although statistically significant, receiver operating characteristic (ROC) curve analysis showed that time spent with maternal BGLs in the range 4¿7 mmol/l [area under the curve (AUC) = 0.58] or 7¿10 mmol (AUC = 0.60) was not strong enough to be a useful clinical predictor of neonatal hypoglycaemia. HbA 1c in the second trimester of pregnancy (P = 0.02, OR 1.42) and percentage time spent in BGL range of 7¿10 mmol/l (P = 0.001, OR 1.02) were both associated with a risk of neonatal hypoglycaemia in a logistic regression model. HbA 1c in the third trimester (P = 0.07, OR 1.28) approached, but did not reach, significance. Conclusions: These data support a BGL range of 4¿7 mmol/l as an intrapartum target. Glycaemic control in the second trimester is associated with neonatal hypoglycaemia. Improvement in ante- and intrapartum glycaemic control may reduce neonatal hypoglycaemia in women with pre-existing diabetes.

© 2017 Elsevier Ltd Background Bronchiolitis is the most common lung infection in infants and treatment focuses on management of respiratory distress and hypoxia. High-flow warm humidified oxygen (HFWHO) is increasingly used, but has not been rigorously studied in randomised trials. We aimed to examine whether HFWHO provided enhanced respiratory support, thereby shortening time to weaning off oxygen. Methods In this open, phase 4, randomised controlled trial, we recruited children aged less than 24 months with moderate bronchiolitis attending the emergency department of the John Hunter Hospital or the medical unit of the John Hunter Children's Hospital in New South Wales, Australia. Patients were randomly allocated (1:1) via opaque sealed envelopes to HFWHO (maximum flow of 1 L/kg per min to a limit of 20 L/min using 1:1 air¿oxygen ratio, resulting in a maximum FiO 2 of 0·6) or standard therapy (cold wall oxygen 100% via infant nasal cannulae at low flow to a maximum of 2 L/min) using a block size of four and stratifying for gestational age at birth. The primary outcome was time from randomisa tion to last use of oxygen therapy. All randomised children were included in the primary and secondary safety analyses. This trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12612000685819. Findings From July 16, 2012, to May 1, 2015, we randomly assigned 202 children to either HFWHO (101 children) or standard therapy (101 children). Median time to weaning was 24 h (95% CI 18¿28) for standard therapy and 20 h (95% CI 17¿34) for HFWHO (hazard ratio [HR] for difference in survival distributions 0·9 [95% CI 0·7¿1·2] ; log rank p=0·61). Fewer children experienced treatment failure on HFWHO (14 [14%]) compared with standard therapy (33 [33%] ; p=0·0016); of these children, those on HFWHO were supported for longer than were those on standard therapy before treatment failure (HR 0·3; 95% CI 0·2¿0·6; p < 0·0001). 20 (61%) of 33 children who experienced treatment failure on standard therapy were rescued with HFWHO. 12 (12%) of children on standard therapy required transfer to the intensive care unit compared with 14 (14%) of those on HFWHO (difference -1%; 95% CI -7 to 16; p=0·41). Four adverse events occurred (oxygen desaturation and condensation inhalation in the HFWHO group, and two incidences of oxygen tubing disconnection in the standard therapy group); none resulted in withdrawal from the trial. No oxygen-related serious adverse events occurred. Secondary effectiveness outcomes are reported in the Results section. Interpretation HFWHO did not significantly reduce time on oxygen compared with standard therapy, suggesting that early use of HFWHO does not modify the underlying disease process in moderately severe bronchiolitis. HFWHO might have a role as a rescue therapy to reduce the proportion of children requiring high-cost intensive care.

© 2017 International Association of Oral and Maxillofacial Surgeons The aim of this study was to determine whether the regional implementation of prohibitive liquor legislation, introduced in order to limit the sale of and access to alcohol, can lead to a sustained reduction in the incidence of assault occasioning facial injury, as seen in patients presenting to a level 1 trauma hospital. A retrospective observational cohort study was conducted to document patients who were identified as an acute hospital presentation of assault occasioning facial injury. The period of study was 2003¿2015; this ensured a similar period of time before and after the implementation of the legislation in 2008. A statistical analysis was undertaken to assess the rates of change in oral and maxillofacial (OMF) assault admissions pre and post legislation. The study found that pre-legislation numbers of OMF assaults increased at a rate of 14% per annum and then decreased at a rate of 21% per annum post legislation (31% relative rate ratio reduction). Similar trends were seen for all males, males aged 18¿35 years, and males where alcohol was recorded at clinical presentation. The introduction of ¿last drinks¿ and ¿lock out¿ legislation has led to a significant and sustained reduction in assaultive alcohol-related facial injury in Newcastle.

© 2017 American Heart Association, Inc. BACKGROUND AND PURPOSE: In alteplase-treated patients with acute ischemic stroke, we investigated the relationship between penumbral reperfusion at 24 hours and clinical outcomes, with and without adjustment for baseline ischemic core volume. RESULTS: This study included 1507 patients. Reperfused penumbral volume had moderate ability to predict 90-day mRS 0 to 1 (area under the curve, 0.77; R2, 0.28; P < 0.0001). However, after adjusting for baseline ischemic core volume, the reperfused penumbral volume was a strong predictor of good functional outcome (area under the curve, 0.946; R2, 0.55; P < 0.0001). For every 1% increase in penumbral reperfusion, the odds of achieving mRS 0 to 1 at day 90 increased by 7.4%. Improvement in acute 24-hour National Institutes of Health Stroke Scale was also significantly related to the degree of reperfused penumbra (R2, 0.31; P < 0.0001). This association was again stronger after adjustment for baseline ischemic core volume (R2, 0.41; P < 0.0001). For each 1% of penumbra that was reperfused, the 24-hour National Institutes of Health Stroke Scale decreased by 0.069 compared with baseline. METHODS: Data were collected from consecutive acute ischemic stroke patients with baseline and follow-up perfusion imaging presenting to hospital within 4.5 hours of symptom onset at 7 hospitals. Logistic regression models were used for predicting the effect of the reperfused penumbral volume on the dichotomized modified Rankin Scale (mRS) at 90 days and improvement of National Institutes of Health Stroke Scale at 24 hours, both adjusted for baseline ischemic core volume. CONCLUSIONS: In patients treated with alteplase, the extent of the penumbra that is reperfused is a powerful predictor of early and late clinical outcomes, particularly when baseline ischemic core is taken into account.

© 2015, Springer-Verlag Berlin Heidelberg. Purpose: To examine the longitudinal association between diet quality and depression using prospective data from the Australian Longitudinal Study on Women¿s Health. Methods: Women born in 1946¿1951 (n¿=¿7877) were followed over 9¿years starting from 2001. Dietary intake was assessed using the Dietary Questionnaire for Epidemiological Studies (version 2) in 2001 and a shortened form in 2007 and 2010. Diet quality was summarised using the Australian Recommended Food Score. Depression was measured using the 10-item Centre for Epidemiologic Depression Scale and self-reported physician diagnosis. Pooled logistic regression models including time-varying covariates were used to examine associations between diet quality tertiles and depression. Women were also categorised based on changes in diet quality during 2001¿2007. Analyses were adjusted for potential confounders. Results: The highest tertile of diet quality was associated marginally with lower odds of depression (OR 0.94; 95¿% CI 0.83, 1.00; P¿=¿0.049) although no significant linear trend was observed across tertiles (OR 1.00; 95¿% CI 0.94, 1.10; P¿=¿0.48). Women who maintained a moderate or high score over 6¿years had a 6¿14¿% reduced odds of depression compared with women who maintained a low score (moderate vs low score¿OR 0.94; 95¿% CI 0.80, 0.99; P¿=¿0.045; high vs low score¿OR 0.86; 95¿% CI 0.77, 0.96; P¿=¿0.01). Similar results were observed in analyses excluding women with prior history of depression. Conclusion: Long-term maintenance of good diet quality may be associated with reduced odds of depression. Randomised controlled trials are needed to eliminate the possibility of residual confounding.

© 2017 Background Access to opioid agonist treatment can be associated with extensive waiting periods with significant health and financial burdens. This study aimed to determine whether patients with heroin dependence dispensed buprenorphine-naloxone weekly have greater reductions in heroin use and related adverse health effects 12-weeks after commencing treatment, compared to waitlist controls and to examine the cost-effectiveness of this strategy. Methods An open-label waitlist RCT was conducted in an opioid treatment clinic in Newcastle, Australia. Fifty patients with DSM-IV-TR heroin dependence (and no other substance dependence) were recruited. The intervention group (n = 25) received take-home self-administered sublingual buprenorphine-naloxone weekly (mean dose, 22.7 ± 5.7 mg) and weekly clinical review. Waitlist controls (n = 25) received no clinical intervention. The primary outcome was heroin use (self-report, urine toxicology verified) at weeks four, eight and 12. The primary cost-effectiveness outcome was incremental cost per additional heroin-free-day. Results Outcome data were available for 80% of all randomized participants. Across the 12-weeks, treatment group heroin use was on average 19.02 days less/month (95% CI -22.98, -15.06, p < 0.0001). A total 12-week reduction in adjusted costs including crime of $A5,722 (95% CI 3299, 8154) in favor of treatment was observed. Excluding crime, incremental cost per heroin-free-day gained from treatment was $A18.24 (95% CI 4.50, 28.49). Conclusion When compared to remaining on a waitlist, take-home self-administered buprenorphine-naloxone treatment is associated with significant reductions in heroin use for people with DSM-IV-TR heroin dependence. This cost-effective approach may be an efficient strategy to enhance treatment capacity.

Background/Aim Web 2.0 internet technology has great potential in promoting physical activity. This trial investigated the effectiveness of a Web 2.0-based intervention on physical activity behaviour, and the impact on website usage and engagement. Methods 504 (328 women, 126 men) insufficiently active adult participants were randomly allocated to one f two web-based interventions or a paper-based Logbook group. The Web 1.0 group participated in the existing 10 000 Steps programme, while the Web 2.0 group participated in a Web 2.0-enabled physical activity intervention including user-to-user interaction through social networking capabilities. ActiGraph GT3X activity monitors were used to assess physical activity at four points across the intervention (0, 3, 12 and 18 months), and usage and engagement were assessed continuously through website usage statistics. Results Treatment groups differed significantly in trajectories of minutes/day of physical activity (p=0.0198), through a greater change at 3 months fo Web 2.0 than Web 1.0 (7.3 min/day, 95% CI 2.4 to 12.3). In the Web 2.0 group, physical activity increased at 3 (mean change 6.8 min/day, 95% CI 3.9 to 9.6) and 12 months (3.8 min/day, 95% CI 0.5 to 7.0), but not 18 months. The Logbook group also increased physical activity at 3 (4.8 min/day, 95% CI 1.8 to 7.7) and 12 months (4.9 min/day, 95% CI 0.7 to 9.1), but not 18 months. The Web 1.0 group increased physical activity at 12 months only (4.9 min/day, 95% CI 0.5 to 9.3). The Web 2.0 group demonstrated higher levels of website engagement (p=0.3964).Conclusions In comparison to a Web 1.0 intervention, a more interactive Web 2.0 intervention, as well as the paper-based Logbook intervention, improved physicalactivity in the short term, but that effect reduced over time, despite higher levels of engagement of the Web 2.0 group. Trial registration number ACTRN12611000157976.

© 2016 Australasian Professional Society on Alcohol and other Drugs Introduction and Aims: Guidelines recommend anxiolytics and hypnotics (A/H) as second-line, short-term medications. We aimed to establish prevalence and associations of A/H prescribing by Australian general practice (GP) trainees. Design and Methods: A cross-sectional analysis from a cohort study of vocational trainees from four GP Regional Training Providers during 2010¿2013. General practice trainees act as independent practitioners (including for prescribing purposes) while having recourse to advice from a GP supervisor. Practice and trainee demographic data were collected as well as patient, clinical and educational data from 60 consecutive consultations of each trainee each training term. Analysis was at the level of individual problem managed, with the outcome factor being prescription of any anxiolytic or hypnotic. Results: Overall, 645 registrars (response rate 94.0%) prescribed 68 582 medications in 69 621 consultations (with 112 890 problems managed). A/Hs were prescribed for 1.3% of problems managed and comprised 2.2% of all prescriptions. They were prescribed particularly for insomnia (28.2%) or anxiety (21.8%), but also for many ¿off-label¿ indications. Significant associations of A/H prescriptions were: patient-level (greater age, Aboriginal and Torres Strait Islander status, English-speaking background, being new to the trainee but not to the practice); trainee-level (male) and consultation-level (longer duration, pre-existing problem, specialist referral not being made). Prescribing was significantly lower in one of the four Regional Training Providers. Discussion and Conclusions: GP trainees, inconsistent with most guideline recommendations, prescribe A/Hs mainly as maintenance therapy to unfamiliar and older patients. Our results suggest that changes in management approaches are needed which may be facilitated by support for psychotherapeutic training.

© The Author 2017. Published by Oxford University Press. All rights reserved. Background. Antibiotic resistance is a public health concern, and is linked to over-prescribing. In self-limiting infections such as acute otitis media (AOM) and acute sinusitis, prescribing remains high despite strong guideline recommendations against the routine use of antibiotics. Early career General Practitioners may find evidence-based prescribing challenging. Aim. To establish the prevalence and associations of antibiotic prescribing for AOM and acute sinusitis by Australian vocational trainees in General Practice. Method. A cross-sectional analysis of data from the Registrar Clinical Encounters in Training (ReCEnT) study. This ongoing, multicentre prospective cohort study documents trainees' consultation-based clinical experiences. Univariate and logistic regression analyses were conducted on data recorded in consultations for AOM or acute sinusitis in nine collection periods during 2010-2014. Results. Data from 856 individual trainees (response rate 95.2%) were analysed. AOM was managed in 0.9% of encounters. Antibiotics were prescribed in 78.8% of cases. Prescribing was significantly associated with longer consultation time and first presentation for this problem. There was no significant association with patient age group. Acute sinusitis was managed in 0.9% of encounters. Antibiotics were prescribed in 71.2% of cases. Later-stage trainees and trainees who did not receive their primary medical qualification in Australia were more likely to prescribe an antibiotic for acute sinusitis. Conclusion. Early career GPs are not prescribing in an evidence-based manner. The complexity of guidelines for AOM and acute sinusitis may be confusing for prescribers, especially early career doctors struggling with inexperience and diagnostic uncertainty. Educational interventions are necessary to bring prescribing rates closer to quality benchmarks.

© 2017 The Authors Worldwide, 10¿20% of adolescents experience mental health problems. Strategies aimed at strengthening resilience protective factors provide a potential approach for reducing mental health problems in adolescents. This study evaluated the effectiveness of a universal, school-based intervention targeting resilience protective factors in reducing mental health problems in adolescents. A cluster randomised controlled trial was conducted in 20 intervention and 12 control secondary schools located in socio-economically disadvantaged areas of NSW, Australia. Data were collected from 3115 students at baseline (Grade 7, 2011), of whom 2149 provided data at follow up (Grade 10, 2014; enrolments in Grades 7 to 10 typically aged 12¿16 years; 50% male; 69.0% retention). There were no significant differences between groups at follow-up for three mental health outcomes: total SDQ, internalising problems, and prosocial behaviour. A small statistically significant difference in favour of the control group was found for externalising problems. Findings highlight the continued difficulties in developing effective, school-based prevention programs for mental health problems in adolescents. Trial registration ANZCTR (Ref no: ACTRN12611000606987).

© 2017 AMPCo Pty Ltd. Produced with Elsevier B.V. All rights reserved. Objectives: To determine the extent to which physical activity reduces the number of hospital bed-days for Australians over 55, using an objective measure of activity. Design, setting and participants: 9784 Newcastle residents aged 55 years or more were invited to participate. 3253 responders were eligible and wore pedometers for one week during 2005e2007; their hospital data from recruitment to 31 March 2015 were analysed (mean follow-up time: 8.2 years). Complete data for 2110 people were available for analysis. Main outcome measures: Mean annual hospital bed-days, according to individual step count. Results: There was a statistically significant reduction in the number of hospital bed-days associated with higher step counts; the incidence rate ratio per extra 1000 steps per day at baseline was 0.91 (95% CI, 0.90e0.94). The disease-specific reductions were significant for admissions for cancer and diabetes, but not for cardiovascular disease. The difference between 4500 and 8800 steps per day (the upper and lower quartile boundaries for step count) was 0.36 bed-days per person per year, after adjusting for age, sex, number of medications, number of comorbidities, smoking and alcohol status, and education. When analysis was restricted to hospital admissions after the first 2 years of follow-up, the difference was 0.29 bed-days per person per year. Conclusions: More active people require less hospital care, and an achievable extra 4300 steps per day would result in an average of one less day in hospital for each 3 years of life.

© 2017 Objective Both computerised and telephone surveys have potential advantages for research data collection. The current study aimed to determine the: (i) feasibility, (ii) acceptability, and (iii) cost per completed survey of computer tablet versus telephone data collection for clients attending an outpatient drug and alcohol treatment clinic. Design Two-arm randomised controlled trial. Method Clients attending a drug and alcohol outpatient clinic in New South Wales, Australia, were randomised to complete a baseline survey via computer tablet in the clinic or via telephone interview within two weeks of their appointment. All participants completed a three-month follow-up survey via telephone. Results Consent and completion rates for the baseline survey were significantly higher in the computer tablet condition. The time taken to complete the computer tablet survey was lower (11¿min) than the telephone condition (17¿min). There were no differences in the proportion of consenters or completed follow-up surveys between the two conditions at the 3-month follow-up. Acceptability was high across both modes of data collection. The cost of the computer tablet condition was $67.52 greater per completed survey than the telephone condition. Conclusion There is a trade-off between computer tablet and telephone data collection. While both data collection methods were acceptable to participants, the computer tablet condition resulted in higher consent and completion rates at baseline, therefore yielding greater external validity, and was quicker for participants to complete. Telephone data collection was however, more cost-effective. Researchers should carefully consider the mode of data collection that suits individual study needs.

© 2017 Royal Australasian College of Physicians Background: Trends in the incidence of acute myocardial infarction (AMI) provide important information for healthcare providers and can allow for accurate planning of future health needs and targeted interventions in areas with an excess burden of cardiovascular disease. Aim: To investigate the regional variations in AMI incidence in the Hunter region. Methods: Incident cases of AMI identified between 1996 and 2013 from the Hunter New England Health Cardiac and Stroke Outcomes Unit were prospectively collected for this study. We calculated crude and age-adjusted incidence of AMI over an 18-year period and explored differences in remoteness, age, sex and indigenous status. Results: During 1996¿2013, a total of 15 480 cases of AMI were identified. There was a significantly higher incidence of AMI in patients from regional areas compared to patients from metropolitan areas. More importantly, while rates of AMI declined by 28% in metropolitan patients, they increased by 8% in regional patients. Males had higher rates of AMI throughout the study period than females, however there was trend over time towards a reduction in AMI incidence in males that was not seen in females. The age-adjusted incidence of AMI for indigenous patients increased by 48% from 2007 to 2013, compared to a 23% decrease in non-indigenous patients. Conclusion: Between 1996 and 2013 in the Hunter region, the adjusted incidence of AMI increased for regional patients compared to metropolitan patients with a trend towards a higher adjusted incidence of AMI in the indigenous population.

© 2017, Springer-Verlag Berlin Heidelberg. Purpose: This study aimed to explore the dyadic relationships between unmet need, depression, and anxiety in people diagnosed with haematological cancer and their support persons. Methods: Adult survivors (18¿years+) who had been diagnosed with a haematological cancer were recruited to a cross-sectional mailed survey via five state cancer registries in Australia. Participating survivors invited a support person to also complete a survey. Structural equation modelling was used to explore the relationships among survivor and support person self-reported depression, anxiety, and unmet needs. Results: Of the 4299 eligible haematological cancer survivors contacted by the registries, 1511 (35%) returned a completed survey as did 1004 support persons. There were 787 dyads with complete data. After adjusting for age, gender, rurality, cancer type, and whether the support person was a relative, positive correlations were found between survivor and support person scores for depression (p¿=¿0.0029) and unmet needs (p¿ < ¿0.001), but not anxiety scores (p¿=¿0.075). Survivor unmet needs were significantly related to support person depression (p¿=¿0.0036). Support person unmet needs were significantly related to a higher depression score for survivors (p¿=¿0.0067). Greater support person unmet needs were significantly related to a higher anxiety score for survivors (p¿=¿0.0083). Survivor unmet needs did not have a significant relationship to support person anxiety (p¿=¿0.78). Conclusion: Unmet needs may mediate the interdependence of psychosocial experiences for survivors and support persons, although a longitudinal study is required to confirm causality. Addressing unmet needs may be a potential target for improving outcomes for both groups.

© 2017 La Trobe University. Limited data exist regarding co-occurring alcohol misuse and depression among general practice patients. This study examined the prevalence of depression by level of alcohol misuse, and the sociodemographic factors associated with depression and increased alcohol misuse severity. A cross-sectional survey was administered to 3559 Australian general practice patients. Patients completed their demographic details, the Patient Health Questionnaire (9-item) and the Alcohol Use Disorder Identification Test (Consumption items). The prevalence of alcohol misuse and depression was 6.7%, and depression prevalence varied significantly according to level of alcohol misuse (P < 0.001). Age, gender, Aboriginality and number of chronic diseases were associated with depression and higher levels of alcohol misuse. These findings may assist General Practitioners in identifying those at risk of experiencing co-morbid depression and alcohol use, and aid in effective treatment and referral.

© 2016 The Australasian College of Dermatologists Background/Objectives: Skin conditions are commonly encountered in general practice but dermatology is underrepresented in undergraduate medical courses. Australian and international studies have shown that the dermatological diagnostic ability of general practitioners (GPs) is suboptimal, contributing to increased dermatology outpatient referrals. Dermatological experience in GP vocational training is thus of particular importance. We aimed to document the prevalence of skin disease presentations and the range of skin diseases encountered by GP trainees. We also sought to establish associations of GP trainee's skin disease experience, including their personal characteristics, consultation factors, and the actions arising from the consultation. Methods: This study took place in the Registrars Clinical Encounters in Training (ReCEnT) study. ReCEnT is an ongoing, prospective, multi-site cohort study of Australian GP trainees' consultations. A descriptive cross-sectional analysis was performed on trainees' consultation data. Results: In total, 645 individual trainees contributed data from 84¿615 consultations. Altogether, 11% of all problems managed were skin problems. Infections, dermatitis, injury and wounds were the most common presentations. Associations of consultations for skin problems (compared with all other problems) included seeking in-consultation advice, planning patient follow up and generating learning goals. Conclusions: These findings suggest GP trainees find skin problems challenging and may indicate a need for more and better targeted undergraduate and GP trainee education.

© 2017, the American Society of Anesthesiologists, Inc. Wolters Kluwer Health, Inc. All Rights Reserved. Background: Halogenated anesthetics activate cardiac ryanodine receptor 2-mediated sarcoplasmic reticulum Ca 2+ release, leading to sarcoplasmic reticulum Ca 2+ depletion, reduced cardiac function, and providing cell protection against ischemia-reperfusion injury. Anesthetic activation of ryanodine receptor 2 is poorly defined, leaving aspects of the protective mechanism uncertain. Methods: Ryanodine receptor 2 from the sheep heart was incorporated into artificial lipid bilayers, and their gating properties were measured in response to five halogenated anesthetics. Results: Each anesthetic rapidly and reversibly activated ryanodine receptor 2, but only from the cytoplasmic side. Relative activation levels were as follows: halothane (approximately 4-fold; n = 8), desflurane and enflurane (approximately 3-fold,n = 9), and isoflurane and sevoflurane (approximately 1.5-fold, n = 7, 10). Half-activating concentrations (K a) were in the range 1.3 to 2.1 mM (1.4 to 2.6 minimum alveolar concentration [MAC]) with the exception of isoflurane (5.3 mM, 6.6 minimum alveolar concentration). Dantrolene (10 µM with 100 nM calmodulin) inhibited ryanodine receptor 2 by 40% but did not alter the K a for halothane activation. Halothane potentiated luminal and cytoplasmic Ca 2+ activation of ryanodine receptor 2 but had no effect on Mg 2+ inhibition. Halothane activated ryanodine receptor 2 in the absence and presence (2 mM) of adenosine triphosphate (ATP). Adenosine, a competitive antagonist to ATP activation of ryanodine receptor 2, did not antagonize halothane activation in the absence of ATP. Conclusions: At clinical concentrations (1 MAC), halothane desflurane and enflurane activated ryanodine receptor 2, whereas isoflurane and sevoflurane were ineffective. Dantrolene inhibition of ryanodine receptor 2 substantially negated the activating effects of anesthetics. Halothane acted independently of the adenine nucleotide-binding site on ryanodine receptor 2. The previously observed adenosine antagonism of halothane activation of sarcoplasmic reticulum Ca 2+ release was due to competition between adenosine and ATP, rather than between halothane and ATP.

© 2017 The Royal Society for Public Health Objective Malaysia has a high and rising prevalence of type 2 diabetes (T2D). While environmental (non-genetic) risk factors for the disease are well established, the role of genetic variations and gene¿environment interactions remain understudied in this population. This study aimed to estimate the relative contributions of environmental and genetic risk factors to T2D in Malaysia and also to assess evidence for gene¿environment interactions that may explain additional risk variation. Study design This was a case¿control study including 1604 Malays, 1654 Chinese and 1728 Indians from the Malaysian Cohort Project. Methods The proportion of T2D risk variance explained by known genetic and environmental factors was assessed by fitting multivariable logistic regression models and evaluating McFadden's pseudo R 2 and the area under the receiver-operating characteristic curve (AUC). Models with and without the genetic risk score (GRS) were compared using the log likelihood ratio Chi-squared test and AUCs. Multiplicative interaction between genetic and environmental risk factors was assessed via logistic regression within and across ancestral groups. Interactions were assessed for the GRS and its 62 constituent variants. Results The models including environmental risk factors only had pseudo R 2 values of 16.5¿28.3% and AUC of 0.75¿0.83. Incorporating a genetic score aggregating 62 T2D-associated risk variants significantly increased the model fit (likelihood ratio P-value of 2.50 × 10 -4 ¿4.83 × 10 -12 ) and increased the pseudo R 2 by about 1¿2% and AUC by 1¿3%. None of the gene¿environment interactions reached significance after multiple testing adjustment, either for the GRS or individual variants. For individual variants, 33 out of 310 tested associations showed nominal statistical significance with 0.001 < P < 0.05. Conclusion This study suggests that known genetic risk variants contribute a significant but small amount to overall T2D risk variation in Malaysian population groups. If gene¿environment interactions involving common genetic variants exist, they are likely of small effect, requiring substantially larger samples for detection.

© 2017, Australasian Medical Journal Pty Ltd. All rights reserved. Background Australia has one of the highest rates of colorectal cancer (CRC) in the world. Data from the National Bowel Cancer Screening Program (NBCSP) suggests that only one third of Australians eligible for CRC screening are up-to-date with CRC screening; however screening occurring outside the program is not captured. Aims This study examines the self-reported CRC screening practices of general practice patients, and the factors associated with being under-screened for CRC. Methods A cross-sectional study conducted in five general practice clinics in NSW from 2015-2017. Participants were aged 50-75 and at average risk of CRC. Participants reported whether they had a faecal occult blood test (FOBT) in the past two years, including the source of FOBT; and whether they had a colonoscopy in the past five years and the reason for colonoscopy. Results Forty-nine per cent of participants completed a FOBT in the past two years. Of these, 62 per cent sourced their FOBT from the NBCSP and 25 per cent from their general practitioner. Thirty-seven per cent of participants reported colonoscopy in the past five years. Of these, 29 per cent received potentially inappropriate colonoscopy. Thirty-two per cent of the samples were classified as under-screened. Older adults were less likely to be under-screened. Conclusion CRC screening rates were higher than those reported by the NBCSP, however a significant proportion of participants remain under-screened. Over one-quarter of participants reporting colonoscopy in the past five years may have undergone unnecessary colonoscopy. These findings indicate that more needs to be done at a general practice level to facilitate risk-appropriate CRC screening.

© 2017 American Academy of Child and Adolescent Psychiatry Objective To examine the effect of universal, school-based, resilience-focused interventions on mental health problems in children and adolescents. Method Eligible studies were randomized controlled trials (RCTs) of universal, school-based interventions that included strategies to strengthen a minimum of 3 internal resilience protective factors, and included an outcome measure of mental health problems in children and adolescents aged 5 to 18 years. Six databases were searched from 1995 to 2015. Results were pooled in meta-analyses by mental health outcome (anxiety symptoms, depressive symptoms, hyperactivity, conduct problems, internalizing problems, externalizing problems, and general psychological distress), for all trials (5-18 years). Subgroup analyses were conducted by age (child: 5-10 years; adolescent: 11-18 years), length of follow-up (short: post-=12 months; long: > 12 months), and gender (narrative). Results A total of 57 included trials were identified from 5,984 records, with 49 contributing to meta-analyses. For all trials, resilience-focused interventions were effective relative to a control in reducing 4 of 7 outcomes: depressive symptoms, internalizing problems, externalizing problems, and general psychological distress. For child trials (meta-analyses for 6 outcomes), interventions were effective for anxiety symptoms and general psychological distress. For adolescent trials (meta-analyses for 5 outcomes), interventions were effective for internalizing problems. For short-term follow-up, interventions were effective for 2 of 7 outcomes: depressive symptoms and anxiety symptoms. For long-term follow-up (meta-analyses for 5 outcomes), interventions were effective for internalizing problems. Conclusion The findings may suggest most promise for using universal resilience-focused interventions at least for short-term reductions in depressive and anxiety symptoms for children and adolescents, particularly if a cognitive-behavioral therapy-based approach is used. The limited number of trials providing data amenable for meta-analysis for some outcomes and subgroups, the variability of interventions, study quality, and bias mean that it is not possible to draw more specific conclusions. Identifying what intervention qualities (such as number and type of protective factor) achieve the greatest positive effect per mental health problem outcome remains an important area for future research.

© The Author 2017. Introduction: Similar to other high-income countries, smoking rates in pregnancy can be high in specific vulnerable groups in Australia. Several clinical guidelines exist, including the 5A's (Ask, Advice, Assess, Assist, and Arrange), ABCD (Ask, Brief advice, Cessation, and Discuss), and AAR (Ask, Advice, and Refer). There is lack of data on provision of smoking cessation care (SCC) of Australian General Practitioners (GPs) and Obstetricians. Methods: A cross-sectional survey explored the provision of SCC, barriers and enablers using the Theoretical Domains Framework, and the associations between them. Two samples were invited: (1) GPs and Obstetricians from a college database (n = 5571) (2) GPs from a special interest group for Indigenous health (n = 500). Dimension reduction for the Theoretical Domains Framework was achieved with factor analysis. Logistic regression was carried out for performing all the 5A's and the AAR. Results: Performing all of the 5A's, ABCD, and AAR "often and always" was reported by 19.9%, 15.6%, and 49.2% respectively. "Internal influences" (such as confidence in counselling) were associated with higher performance of the 5A's (Adjusted OR 2.69 (95% CI 1.5, 4.8), p < .001), whereas "External influences" (such as workplace routine) were associated with higher performance of AAR (Adjusted OR 1.7 (95% CI 1, 2.8), p =.035). Conclusions: Performance in providing SCC to pregnant women is low among Australian GPs and Obstetricians. Training clinicians should focus on improving internal influences such as confidence and optimism. The AAR may be easier to implement, and interventions at the service level should focus on ensuring easy, effective, and acceptable referral mechanisms are in place. Implications: Improving provision of the 5A's approach should focus on the individual level, including better training for GPs and Obstetricians, designed to improve specific "internal" barriers such as confidence in counselling and optimism. The AAR may be easier to implement in view of the higher overall performance of this approach. Interventions on a more systemic level need to ensure easy, effective, and acceptable referral mechanisms are in place. More research is needed specifically on the acceptability of the Quitline for pregnant women, both Indigenous and non-Indigenous.

© 2016 Academy of Nutrition and Dietetics Background Consumption of dietary carotenoids from fruits and vegetables (F/V) leads to accumulations in human skin, altering skin yellowness. The influence of the quantity of F/V consumed on skin yellowness and plasma carotenoid concentrations has not been examined previously. Objective To compare the influence of consuming high-carotenoid-containing F/V (HCFV) (176,425 µg beta carotene/wk) vs low-carotenoid F/V (LCFV) (2,073 µg beta carotene/wk) on skin yellowness and plasma carotenoid concentrations, over 4 weeks. Design and intervention A single-blind randomized controlled crossover trial from October 2013 to March 2014. Thirty women were randomized to receive 7 daily servings of HCFV or LCFV for 4 weeks. Following a 2-week washout period they followed the alternate intervention. Main outcome measures Skin color (Commission Internationale de l'Eclairage L*a*b* color space, where L* represents skin lightness and positive values of a* and b* represent degrees of redness and yellowness, respectively) was assessed by reflectance spectroscopy in both sun-exposed and nonexposed skin areas. Fasting plasma carotenoids were determined by high-performance liquid chromatography, before and after each intervention period. Statistical analyses performed Linear mixed models were used to determine the HCFV and LCFV response on skin color and plasma carotenoids, adjusting for intervention order, time, and interaction between baseline differences and time. Results There were no significant differences in mean daily fruit (P=0.42) and vegetable (P=0.17) intakes between HCFV and LCFV groups. Dietary alpha carotene, beta carotene, lutein, and beta cryptoxanthin intakes were significantly different between the two groups (P < 0.01). Following HCFV there was a significantly greater increase in skin yellowness (b*) in both sun-exposed (P < 0.001) and unexposed areas, (P < 0.001), with no change in skin lightness (L*) or redness (a*). Significantly higher plasma alpha carotene (P=0.004), beta carotene (P=0.001), and lutein (P=0.028) concentrations were found following the HCFV intervention. Skin yellowness correlated with alpha carotene and beta carotene. Conclusions Skin yellowness (b*) and fasting plasma carotenoid concentrations were significantly higher following HCFV than LCFV over 4 weeks.

© AHHA 2016. Objective To establish prevalence and associations of general practice nurses' (GPNs) involvement in general practitioner (GP) registrars' consultations. Methods A cross-sectional analysis from an ongoing cohort study of registrars' clinical consultations in five Australian states. Registrars recorded detailed data from 60 consecutive consultations per 6-month training term. Problems and diagnoses encountered, including chronic disease classification, were coded using the International Classification of Primary Care, second edition duplication system (ICPC-2plus) classification system. The outcome factor in our analysis was GPN involvement in management of individual problems and diagnoses. Independent variables were a range of patient, registrar, practice, consultation and educational factors. Results We analysed 108759 consultations of 856 registrars including 169307 problems or diagnoses. Of the problems/diagnoses, 5.1% (95% confidence interval (CI) 5.0-5.2) involved a GPN. Follow-up with a GPN was organised for 1.5% (95% CI 1.4-1.5) of all problems/diagnoses. Significant associations of GPN involvement included patient age, male sex, Aboriginal or Torres Strait Islander status, non-English-speaking background (NESB) and the patient being new to the practice. Larger practice size, the particular training organisation, and the problem/diagnosis being new and not a chronic disease were other associations. Conclusions Associations with Aboriginal or Torres Strait Islander status and NESB status suggest GPNs are addressing healthcare needs of these under-serviced groups. But GPNs may be underutilised in chronic disease care. What is known about this topic? GPNs are increasingly involved in team-based care in Australian general practice. The potential positive contribution of GPNs to general practice teams is acknowledged, but the role of the GPN is still being refined. What does this paper add? GPNs contribute to the care of a modest proportion of patients seen by GP registrars. Aboriginal or Torres Strait Islander status and NESB of patients are positively associated with being seen by a GPN; chronic disease is negatively associated with being seen by a GPN. There is geographic variability in prevalence of GPN consultations, not explained by other factors. What are the implications for practitioners? Given the match of GPN skills and attributes to the needs of patients with chronic diseases, GPNs currently may be underutilised in chronic disease care in Australian general practice. The marked geographic variation in uptake of GPNs also suggests scope for greater utilisation of GPNs Australia-wide.

© 2016 Nature America, Inc. Very few genetic variants have been associated with depression and neuroticism, likely because of limitations on sample size in previous studies. Subjective well-being, a phenotype that is genetically correlated with both of these traits, has not yet been studied with genome-wide data. We conducted genome-wide association studies of three phenotypes: subjective well-being (n = 298,420), depressive symptoms (n = 161,460), and neuroticism (n = 170,911). We identify 3 variants associated with subjective well-being, 2 variants associated with depressive symptoms, and 11 variants associated with neuroticism, including 2 inversion polymorphisms. The two loci associated with depressive symptoms replicate in an independent depression sample. Joint analyses that exploit the high genetic correlations between the phenotypes (P = 0.8) strengthen the overall credibility of the findings and allow us to identify additional variants. Across our phenotypes, loci regulating expression in central nervous system and adrenal or pancreas tissues are strongly enriched for association.

© The Author 2015. Published by Oxford University Press. Genome-wide association studies have previously identified 23 genetic loci associated with circulating fibrinogen concentration. These studies used HapMap imputation and did not examine the X-chromosome. 1000 Genomes imputation provides better coverage of uncommon variants, and includes indels.We conducted a genome-wide association analysis of 34 studies imputed to the 1000 Genomes Project reference panel and including ~120 000 participants of European ancestry (95 806 participants with data on the X-chromosome). Approximately 10.7 million single-nucleotide polymorphisms and 1.2 million indelswere examined.We identified 41 genome-wide significant fibrinogen loci; of which, 18were newly identified. Therewere no genome-wide significant signals on the X-chromosome. The lead variants of five significant loci were indels. We further identified six additional independent signals, including three rare variants, at two previously characterized loci: FGB and IRF1. Together the 41 loci explain 3% of the variance in plasma fibrinogen concentration.

© The Author 2016. Published by Oxford University Press. All rights reserved. Background: Acute sore throat is a common condition presenting to family practitioners. It is usually self-limiting, with antibiotic treatment recommended only for high-risk presentations. Overprescribing of antibiotics contributes to individual and community resistance. Learning to prescribe in the context of diagnostic uncertainty and patient pressures is a challenge for early-career doctors. Prescribing habits develop early and tend not to change with time. Objective: To establish the prevalence and associations of antibiotic prescribing for acute sore throat by Australian vocational trainees in family practice. Method: A cross-sectional analysis of data from the Registrar Clinical Encounters in Training (ReCEnT) study. This ongoing, multicentre prospective cohort study documents the nature of trainees' consultation-based clinical experiences. Univariate and logistic regression analyses were conducted on data recorded in consultations for sore throat in nine collection periods during 2010-14. Results: Data from 856 individual trainees (response rate 95.2%) were analysed. Sore throat was managed in 2.3% encounters. Antibiotics were prescribed for 71.5% of sore throat diagnoses. The variables associated with prescribing were inner-regional location and higher socio-economic area. There was no significant association with younger age of patient or greater trainee experience. If an antibiotic was prescribed, the trainee was more likely to seek information from guidelines or a supervisor. Conclusions: The high frequency of antibiotic prescribing and the lack of attenuation in prescribing with increased experience suggest current educational interventions and the apprenticeship model of training is not fostering appropriate practice in this important clinical area. Targeted educational interventions, for supervisors as well as trainees, are indicated.

© 2016 Kay-Lambkin et al. Background: People with bipolar disorder (BD) have a mortality gap of up to 20 years compared to the general population. Physical conditions, such as cardiovascular disease (CVD) and cancer, cause the majority of excess deaths in psychiatric populations and are the leading causes of mortality in people with BD. However, comparatively little attention has been paid to reducing the risk of physical conditions in psychiatric populations. Unhealthy lifestyle behaviors are among the potentially modifiable risk factors for a range of commonly comorbid chronic medical conditions, including CVD, diabetes, and obesity. This systematic review will identify and evaluate the available evidence for effective interventions to reduce risk and promote healthy lifestyle behaviors in BD. Methods/design: We will search MEDLINE, Embase, PsychINFO, Cochrane Database of Systematic Reviews, and CINAHL for published research studies (with at least an abstract published in English) that evaluate behavioral or psychosocial interventions to address the following lifestyle factors in people with BD: tobacco use, physical inactivity, unhealthy diet, overweight or obesity, sleep-wake disturbance, and alcohol/other drug use. Primary outcomes for the review will be changes in tobacco use, level of physical activity, diet quality, sleep quality, alcohol use, and illicit drug use. Data on each primary outcome will be synthesized across available studies in that lifestyle area (e.g., tobacco abstinence, cigarettes smoked per day), and panel of research and clinical experts in each of the target lifestyle behaviors and those experienced with clinical and research with individuals with BD will determine how best to represent data related to that primary outcome. Seven members of the systematic review team will extract data, synthesize the evidence, and rate it for quality. Evidence will be synthesized via a narrative description of the behavioral interventions and their effectiveness in improving the healthy lifestyle behaviors in people with BD. Discussion: The planned review will synthesize and evaluate the available evidence regarding the behavioral or psychosocial treatment of lifestyle-related behaviors in people with BD. From this review, we will identify gaps in our existing knowledge and research evidence about the management of unhealthy lifestyle behaviors in people with BD. We will also identify potential opportunities to address lifestyle behaviors in BD, with a view to reducing the burden of physical ill-health in this population.

The precursor for nerve growth factor (proNGF) is expressed in some cancers but its clinicopathological significance is unclear. The present study aimed to define the clinicopathological significance of proNGF in thyroid cancer. ProNGF expression was analysed by immunohistochemistry in two cohorts of cancer versus benign tumors (adenoma) and normal thyroid tissues. In the first cohort (40 thyroid cancers, 40 thyroid adenomas and 80 normal thyroid tissues), proNGF was found overexpressed in cancers compared to adenomas and normal samples (p < 0.0001). The area under the receiver-operating characteristic (ROC) curve was 0.84 (95% CI 0.75-0.93, p < 0.0001) for cancers versus adenomas, and 0.99 (95% CI 0.98-1.00, p < 0.0001) for cancers versus normal tissues. ProNGF overexpression was confirmed in a second cohort (127 cancers of various histological types and 55 normal thyroid tissues) and using a different antibody (p < 0.0001). ProNGF staining intensity was highest in papillary carcinomas compared to other histological types (p < 0.0001) and there was no significant association with age, gender, tumor size, stage and lymph node status. In conclusion, proNGF is increased in thyroid cancer and should be considered as a new potential diagnostic biomarker.

© 2016 The Author(s). Background: Population-based registries are increasingly used to recruit patient samples for research, however, they have several limitations including low consent and participation rates, and potential selection bias. To improve access to samples for research, the utility of a new model of recruitment termed the 'Consumer Register', that allows for direct patient recruitment from hospitals, was examined. This paper reports: (i) consent rates onto the register; (ii) preferred methods and frequency of contact; and (iii) the feasibility of establishing the register, including: (a) cost per person recruited to the register; (b) the differential cost and consent rates of volunteer versus paid data collectors; and (c) participant completion rates. Methods: A cross-sectional survey was conducted in five outpatient clinics in Australia. Patients were approached by volunteers or paid data collectors and asked to complete a touch-screen electronic survey. Consenting individuals were asked to indicate their willingness and preferences for enrolment onto a research register. Descriptive statistics were used to examine patient preferences and linear regression used to model the success of volunteer versus paid data collectors. The opportunity and financial costs of establishing the register were calculated. Results: A total of 1947 patients (80.6 %) consented to complete the survey, of which, 1486 (76.3 %) completed the questionnaire. Of the completers, the majority (69.4 %, or 1032 participants) were willing to be listed on the register and preferred to be contacted by email (50.3 %). Almost 39 % of completers were willing to be contacted three or more times in a 12 month period. The annual opportunity cost of resources consumed by the register was valued at $37,187, giving an opportunity cost per person recruited to the register of $36. After amortising fixed costs, the annual financial outlay was $23,004 or $22 per person recruited to the register. Use of volunteer data collectors contributed to an annual saving of $14,183, however paid data collectors achieved significantly higher consent rates. Successful enrolment onto the register was completed for 42 % of the sample. Conclusions: A Consumer Register is a promising and feasible alternative to population-based registries, with the majority of participants willing to be contacted multiple times via low-resource methods such as email. There is an effectiveness/cost trade off in the use of paid versus volunteer data collectors.

Background: Cancer treatments can have long-term physical, psychological, financial, sexual and cognitive effects that may influence the quality of life. These can vary from urban to rural areas, survival period and according to the type of cancer. We here aimed to describe demographics and psychosocial analysis of cancer survivors three to five years post-treatment in rural Australia and also assess relationships with financial stress and quality of life domains. Materials and Methods: In this cross-sectional study, 65 participants visiting the outpatient oncology clinic were given a self-administered questionnaire. The inclusion criteria included three to five years post-treatment. Three domains were investigated using standardised and validated tools such as the Standard Quality of Life in Adult Cancer Survivors Scale (QLACS) and the Personal and Household Finances (HILDA) survey. Included were demographic parameters, quality of life, treatment information and well-being. Results: There was no evidence of associations between any demographic variable and either financial stress or cancer-specific quality of life domains. Financial stress was however significantly associated with the cancerspecific quality of life domains of appearance-related concerns, family related distress, and distress related to recurrence. Conclusions: This unique study effectively points to psychosocial aspects of cancer survivors in rural regions of Australia. Although the majority of demographic characteristics were not been found to be associated with financial stress, this latter itself is significantly associated with distress related to family and cancer recurrence. This finding may be of assistance in future studies and also considering plans to fulfil unmet needs.

© 2016, Springer-Verlag Berlin Heidelberg. Purpose: The importance of distress identification and management in oncology has been established. We examined the relationship between distress and unmet bio-psychosocial needs, applying advanced statistical techniques, to identify which needs have the closest relationship to distress. Methods: Oncology outpatients (n¿=¿1066) undergoing QUICATOUCH screening in an Australian cancer centre completed the distress thermometer (DT) and problem list (PL). Principal component analysis (PCA), logistic regression and classification and regression tree (CART) analyses tested the relationship between DT score (at a cut-off point of 4) and PL items. Results: Sixteen items were reported by < 5¿% of participants. PCA analysis identified four major components. Logistic regression analysis indicated three of these component scores, and four individual items (20 items in total) demonstrated a significant independent relationship with distress. The best CART model contained only two PL items: ¿worry¿ and ¿depression¿. Conclusions: The DT and PL function as intended, quantifying negative emotional experience (distress) and identifying bio-psychosocial sources of distress. We offer two suggestions to minimise PL response time whilst targeting PL items most related to distress, thereby increasing clinical utility. To identify patients who might require specialised psychological services, we suggest the DT followed by a short, case-finding instrument for patients over threshold on the DT. To identify other important sources of distress, we suggest using a modified PL of 14 key items, with the 15th item ¿any other problem¿ as a simple safety net question. Shorter times for patient completion and clinician response to endorsed PL items will maximise acceptance and clinical utility.

Copyright © The Authors 2016. There is increasing evidence for the role of nutrition in the prevention of depression. This study aims to describe changes in diet quality over 12 years among participants in the Australian Longitudinal Study on Women's Health in relation to changes in depressive symptoms. Women born between 1946 and 1951 were followed-up for 12 years (2001-2013). Dietary intake was assessed using the Dietary Questionnaire for Epidemiological Studies (version 2) in 2001, 2007 and every 2-3 years after that until 2013. Diet quality was summarised using the Australian Recommended Food Score (ARFS). Depressive symptoms were measured using the ten-item Centre for Epidemiologic Depression Scale at every 2-3-year intervals during 2001-2013. Linear mixed models were used to examine trends in diet quality and its sub-components. The same model including time-varying covariates was used to examine associations between diet quality and depressive symptoms adjusting for confounders. Sensitivity analyses were carried out using the Mediterranean dietary pattern (MDP) index to assess diet quality. Minimal changes in overall diet quality and its sub-components over 12 years were observed. There was a significant association between baseline diet quality and depression (ß=-0 24, P=0 001), but this was lost when time-varying covariates were added (ß=-0 04, P=0 10). Sensitivity analyses showed similar performance for both ARFS and MDP in predicting depressive symptoms. In conclusion, initial associations seen when using baseline measures of diet quality and depressive symptoms disappear when using methods that handle time-varying covariates, suggesting that previous studies indicating a relationship between diet and depression may have been affected by residual confounding.

© The Author 2016. Published by Oxford University Press in association with the International Society for Quality in Health Care. All rights reserved. Objectives: To identify specific actions for patient-centred quality improvement in chronic disease outpatient settings, this study identified patients' general and specific preferences among a comprehensive suite of initiatives for change.Design and setting: A cross-sectional survey was conducted in three hospital-based clinics specializing in oncology, neurology and cardiology care located in New South Wales, Australia.Participants and measures: Adult English-speaking outpatients completed the touch-screen Consumer Preferences Survey in waiting rooms or treatment areas. Participants selected up to 23 general initiatives that would improve their experience. Using adaptive branching, participants could select an additional 110 detailed initiatives and complete a relative prioritization exercise.Results: A total of 541 individuals completed the survey (71.1% consent, 73.1% completion). Commonly selected general initiatives, presented in order of decreasing priority (along with sample proportion), included: improved parking (60.3%), up-to-date information provision (15.0%), ease of clinic contact (12.9%), access to information at home (12.8%), convenient appointment scheduling (14.2%), reduced wait-times (19.8%) and information on medical emergencies (11.1%). To address these general initiatives, 40 detailed initiatives were selected by respondents.Conclusions: Initiatives targeting service accessibility and information provision, such as parking and up-to-date information on patient prognoses and progress, were commonly selected and perceived to be of relatively greater priority. Specific preferences included the need for clinics to provide patient-designated parking in close proximity to the clinic, information on treatment progress and test results (potentially in the form of designated brief appointments or via telehealth) and comprehensive and trustworthy lists of information sources to access at home.

© 2014 John Wiley & Sons Ltd Studies have identified prenatal flavour exposure as a determinant of taste preferences in infants; however, these studies have focused on relatively small samples and limited flavours. As many parents struggle with getting children to accept a variety of nutritious foods, a study of the factors influencing food acceptance is warranted. The objective of this study was to determine whether exposure to a wider variety of fruit and vegetables and overall higher diet quality in utero results in acceptance of a greater variety of these foods and better diet quality for offspring during childhood. This study is a secondary data analysis of pregnant women (n = 52) and their resulting offspring recruited for the Women and Their Children's Health study in NSW, Australia. Dietary intake of mothers and children was measured using food frequency questionnaires. Diet quality and vegetable and fruit variety were calculated using the Australian Recommended Food Score and the Australian Chil d and Adolescent Recommended Food Score. Associations between maternal and child diet quality and variety were assessed using Pearson's correlations and the total effect of in utero maternal pregnancy diet on childhood diet was decomposed into direct and indirect effect using mediation analysis. Maternal pregnancy and post-natal diet were both correlated with child diet for overall diet quality and fruit and vegetable variety (P < 0.001). Mediation analyses showed that the indirect effect of maternal pregnancy diet on child diet was mediated through maternal post-natal diet, particularly for fruit (P = 0.045) and vegetables (P = 0.055). Nutrition intervention should therefore be aimed at improving diet quality and variety in mothers with young children, in order to subsequently improve eating habits of offspring.

© 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd Objective: Retrospective continuous glucose monitoring (CGM) can guide insulin pump adjustments, however, interpretation of data and recommending new pump settings is complex and subjective. We aimed to compare the safety and glycaemic profiles of children after their diabetologist or a novel algorithm (PumpTune) adjusted their insulin pump settings. Research design and methods: In a randomized cross-over trial of 22 patients aged 6¿14 yr with type 1 diabetes with mean Hba1c 7.4% (57 mmol/mol) using CSII, CGM was used over two periods each of 6.5 d to assess percentage time glucose remained within, above and below 3.9¿10.0 mmol/L. Before the start of one period pump settings were adjusted by the patient's diabetologist, and before the other insulin pump settings were adjusted by PumpTune. Results: A total of 63.4% of the sensor glucose levels were within target range with PumpTune settings and 57.4% were within range with the clinician settings (p = 0.016). The time spent above target range with PumpTune was 26.9% and with clinician settings was 33.5% (p = 0.021). The time spent below target range with PumpTune was 9.7% and with clinician settings was 9.2% (p = 0.77). The mean number of times when a sensor glucose level < 2.75 mmol/L was recorded with PumpTune settings was 2.9 compared with 3.7 with clinician settings (p = 0.39). There were no serious adverse outcomes and no difference in parent-assessed satisfaction. Conclusions: Automated insulin pump adjustment with PumpTune is feasible and warrants testing in a larger more varied population over a longer time. In this well-controlled group of children, PumpTune achieved a more favorable glucose profile.

© Copyright 2016 Wolters Kluwer Health, Inc. Elevations in postmortem vitreous sodium chloride (PMVSC) levels may help in differentiating saltwater/seawater drowning (SWD) deaths from immersion deaths not related to drowning (DNRD). It is unclear whether the elevation is related to blood/plasma electrolyte changes after inhalation of seawater as hypothesized in SWDs or possibly caused by electrolyte diffusion and/or osmosis across the outer coats of the eyeball during immersion. Aim: To investigate the changes in bovine PMVSC levels at different time points while immersed in seawater. Methods: Bovine eyeballs were obtained from an abattoir and randomized into 2 groups: A) submerged in seawater ("wet" group) or b) placed in an impermeable plastic bag that was immersed in seawater ("dry" group). The PMVSC levels from 6 eyeballs were measured from each group (without replacement) at 30 minutes, 1 hour, 6 hours, and 12 hours. Results: There was no significant difference in mean PMVSC levels between the 2 groups at 30-minute and 1-hour intervals. A significant difference was noted from 6 hours onward. Discussion: There is no statistically significant elevation in bovine PMVSC levels when immersed in seawater for up to 1 hour. Assuming similar physical properties in humans, any elevations in PMVSC levels in bodies immersed in seawater for less than 1 hour should not be caused by immersion.

© 2016 Background Previous studies in salt water drowning deaths (SWD) demonstrated an observable elevation of post mortem vitreous sodium and chloride (PMVSC) levels. It remains unclear what the underlying mechanism responsible for this change is: whether this is due to rapid electrolyte changes from salt water inhalation/ingestion during drowning or from electrolyte diffusion and/or osmosis across the outer coats of the eyeballs during immersion. A recent animal study using sacrificed bovine eyeballs immersed in salt water demonstrated no significant elevations in PMVSC when immersed for less than one hour. Assuming similar physical properties between human and bovine, we extrapolate that an elevation in PMVSC in SWD with immersion times of less than one hour (SWD-1) would not be from immersion, but from drowning. Aim Investigate whether there is an elevation in PMVSC in SWD-1. Methods Retrospective study comparing PMVSC in SWD-1 with controls from 2012 to 2015 inclusive. Results PMVSC in SWD-1 was significantly elevated compared with controls. A PMVSC of 259¿mmol/L has a sensitivity, specificity and likelihood ratio of 0.9, 0.9 and 7.6, respectively. Conclusion The elevation in PMVSC in SWD-1 is due to drowning. A PMVSC of 259¿mmol/L and above is a reliable ancillary test in diagnosing drowning in bodies immersed in salt water for less than one hour.

Copyright © 2016 by American Society of Clinical Oncology. Purpose This cross-sectional study assessed the association between oncology outpatients' quality improvement preferences and health-related quality of life (HRQoL). Implementation of specific initiatives preferred by patients with lower HRQoL may be a strategic approach to enhancing care for potentially vulnerable patients. Methods English-speaking adults were recruited from five outpatient chemotherapy clinics located in New South Wales, Australia. Using touch screen devices, participants selected up to 25 initiatives that would improve their experiences and completed the Functional Assessment of Cancer Therapy-General (FACT-G) survey. The logistic odds of selecting an initiative according to FACT-G scores were calculated to determine whether preferences were associated with HRQoL after controlling for potential confounders. Results Of the 411 eligible outpatients approached to participate, 263 (64%) completed surveys. Commonly selected initiatives were up-to-date information on treatment and condition progress (19.8%), access to or information on financial assistance (18.3%), and reduced clinic wait times (17.5%). For those with relatively lower FACT-G scores, the adjusted odds of selecting five initiatives illustrated an increasing trend: convenient appointment scheduling systems (+23% [P =.002]), reduced wait times (+15% [P =.01] ), information on medical emergencies (+14% [P =.04]), access to or information on financial assistance (+15% [P =.009] ), help to maintain daily living activities (+18% [P =.007]). Conclusion Two areas of improvement were commonly selected: easily accessible health services and information and support for self-management. Although the results suggest an association between a few q uality improvement preferences and HRQoL, a wider spectrum of patient characteristics must be considered when targeting quality improvement to patient subgroups.

© 2015 The Authors. Objective: General practice is central to Aboriginal and Torres Strait Islander health care, and this area is a core element of Australian general practice (GP) training. We aimed to describe the prevalence, nature and associations of GP registrar encounters with Aboriginal and Torres Strait Islander patients. Methods: A cross-sectional analysis from a cohort study of GP registrars' clinical consultations 2010-2013. Registrars record demographic, clinical and educational details of consecutive patient encounters. Multivariable associations were tested with logistic regression. Results: A total of 592 registrars contributed data from 69,188 consultations. Encounters with Aboriginal and Torres Strait Islander patients comprised 1.0% of consultations. Significant positive associations included younger patient age; new patient to the registrar; lower socioeconomic status of practice location; non-urban practice setting; more problems managed; and follow-up arranged. A greater proportion of Aboriginal and Torres Strait Islander patients' problems were psychological/social and a lesser proportion were cardiovascular. Consultation duration did not differ between the two groups Conclusions: GP registrars encounter Aboriginal and Torres Strait Islander patients less than do established GPs. Our results suggest possible variability in registrar experience of Aboriginal and Torres Strait Islander health. Implications: Our findings will inform training of a culturally and clinically competent workforce in this area.

© 2016 Elsevier Inc. Antioxidants and fatty acids are associated with depression and inflammation, and inflammation appears to predict depression risk; hence, the associations between these nutrients and depression may be mediated by inflammation. We hypothesized that inflammatory markers interleukin (IL)-6 and C-reactive protein (CRP) mediate the associations between antioxidant and fatty acid intakes, and depression. Participants were from the Hunter Community Study, a longitudinal cohort of adults aged 55-85 years. Dietary intake was assessed using the Older Australian's Food Frequency Questionnaire. Fasting blood samples were drawn for analysis of nutrient and inflammatory biomarkers. Depressive symptoms were assessed using the 20-item Center for Epidemiologic Studies-Depression scale at baseline and at 5-year follow-up. Linear mixed models were used to investigate longitudinal associations between dietary intakes and depression, and mediation analyses were carried out to determine if IL-6 and/or CRP were the mediators. Analyses were conducted on men and women separately and adjusted for potential confounders. Fruit and monounsaturated fat intakes were negatively associated with depression, whereas total fat and saturated fat intakes were positively associated with depression in both sexes. Omega-3 polyunsaturated fat was inversely associated with depression in men only. IL-6 was a significant mediator of the association between fruits with low carotenoid content and depression in women. CRP significantly mediated the relationship between total fat, saturated fat, and monounsaturated fat intakes and depression in women, and saturated fat intake and depression in men. Our findings raise the possibility that the association between fatty acid intake and depression is partially mediated by inflammatory markers.

© 2015 The Authors. Objectives: To document the frequency of recording of Aboriginal and Torres Strait Islander status in general practice (GP) clinical records and to establish associations of this recording. Methods: Cross-sectional analysis of recording of patients' Aboriginal and Torres Strait Islander status in GP clinical records from GP training practices in four Australian states. Results: Of the 9,704 clinical records examined, the patients' Aboriginal and Torres Strait Islander status had been documented in 5,165 (53.2%). Higher rates of recording were associated with older patient age, practices outside a major city, patients who were not new to the practice and the patient being Aboriginal and Torres Strait Islander. In encounters with Aboriginal and Torres Strait Islander patients, the patient's status had been documented in 82% of records. Those attending larger practices were less likely to have had their status recorded. Conclusions: This is the first report of Aboriginal and Torres Strait Islander status recording in GP clinical records. Almost 20% of Aboriginal and Torres Strait Islander patients did not have their status recorded in the clinical record, with indications that recording may be unsystematic. Implications: Our findings reinforce the need for a systematic approach to identification of Aboriginal and Torres Strait Islander status in general practice and will inform policy and practice in this important area.

© 2016 Macmillan Publishers Limited All rights reserved. To identify common variants contributing to normal variation in two specific domains of cognitive functioning, we conducted a genome-wide association study (GWAS) of executive functioning and information processing speed in non-demented older adults from the CHARGE (Cohorts for Heart and Aging Research in Genomic Epidemiology) consortium. Neuropsychological testing was available for 5429-32 070 subjects of European ancestry aged 45 years or older, free of dementia and clinical stroke at the time of cognitive testing from 20 cohorts in the discovery phase. We analyzed performance on the Trail Making Test parts A and B, the Letter Digit Substitution Test (LDST), the Digit Symbol Substitution Task (DSST), semantic and phonemic fluency tests, and the Stroop Color and Word Test. Replication was sought in 1311-21860 subjects from 20 independent cohorts. A significant association was observed in the discovery cohorts for the single-nucleotide polymorphism (SNP) rs17518584 (discovery P-value=3.12 × 10 -8) and in the joint discovery and replication meta-analysis (P-value=3.28 × 10 -9 after adjustment for age, gender and education) in an intron of the gene cell adhesion molecule 2 (CADM2) for performance on the LDST/DSST. Rs17518584 is located about 170 kb upstream of the transcription start site of the major transcript for the CADM2 gene, but is within an intron of a variant transcript that includes an alternative first exon. The variant is associated with expression of CADM2 in the cingulate cortex (P-value=4 × 10 -4). The protein encoded by CADM2 is involved in glutamate signaling (P-value=7.22 × 10 -15), gamma-aminobutyric acid (GABA) transport (P-value=1.36 × 10 -11) and neuron cell-cell adhesion (P-value=1.48 × 10 -13). Our findings suggest that genetic variation in the CADM2 gene is associated with individual differences in information processing speed.

BACKGROUND: Population-based registries are increasingly used to recruit patient samples for research, however,¿they have several limitations including low consent and participation rates, and potential selection bias. To improve access to samples for research, the utility of a new model of recruitment termed the 'Consumer Register', that allows for direct patient recruitment from hospitals, was examined. This paper reports: (i) consent rates onto the register; (ii) preferred methods and frequency of contact; and (iii) the feasibility of establishing the register, including: (a) cost per person recruited to the register; (b) the differential cost and consent rates of volunteer versus paid data collectors; and (c) participant completion rates. METHODS: A cross-sectional survey was conducted in five outpatient clinics in Australia. Patients were approached by volunteers or paid data collectors and asked to complete a touch-screen electronic survey. Consenting individuals were asked to indicate their willingness and preferences for enrolment onto a research register. Descriptive statistics were used to examine patient preferences and linear regression used to model the success of volunteer versus paid data collectors. The opportunity and financial costs of establishing the register were calculated. RESULTS: A total of 1947 patients (80.6¿%) consented to complete the survey, of which, 1486 (76.3¿%) completed the questionnaire. Of the completers, the majority (69.4¿%, or 1032 participants) were willing to be listed on the register and preferred to be contacted by email (50.3¿%). Almost 39¿% of completers¿were willing to be contacted three or more times in a 12¿month period. The annual opportunity cost of resources consumed by the register was valued at $37,187, giving an opportunity cost per person recruited to the register of $36. After amortising fixed costs, the annual financial outlay was $23,004 or $22 per person recruited to the register. Use of volunteer data collectors contributed to an annual saving of $14,183, however paid data collectors achieved significantly higher consent rates. Successful enrolment onto the register was completed for 42 % of the sample. CONCLUSIONS: A Consumer Register is a promising and feasible alternative to population-based registries, with the majority of participants willing to be contacted multiple times via low-resource methods such as email. There is an effectiveness/cost trade off in the use of paid versus volunteer data collectors.

© 2016 AMPCo Pty Ltd. Objective: The system of care in the Hunter New England Local Health District for patients with ST-segment elevation myocardial infarction (STEMI) foresees pre-hospital thrombolysis (PHT) administered by paramedics to patients more than 60 minutes from the cardiac catheterisation laboratory (CCL), and primary percutaneous coronary intervention (PCI) at the CCL for others. We assessed the safety and effectiveness of the pre-hospital diagnosis strategy, which allocates pat ients to PHT or primary PCI according to travel time to the CCL. Design, setting and participants: Prospective, non-randomised, consecutive, single-centre case series of STEMI patients diagnosed on the basis of a pre-hospital electrocardiogram (ECG), from August 2008 to August 2013. All patients were treated at the tertiary referral hospital (John Hunter Hospital, Newcastle). Main outcome measures: The primary efficacy endpoint was all-cause mortality at 12 months; the primary safety endpoint was bleeding. Results: STEMI was diagnosed in 484 patients on the basis of pre-hospital ECG; 150 were administered PHT and 334 underwent primary PCI. The median time from first medical contact (FMC) to PHT was 35 minutes (IQR, 28¿43 min) and to balloon inflation 130 minutes (IQR, 100¿150 min). In the PHT group, 37 patients (27%) needed rescue PCI (median time, 4 h; IQR, 3¿5 h). The 12-month all-cause mortality rate was 7.0% (PHT, 6.7%; PCI, 7.2%). The incidence of major bleeding (TIMI criteria) in the PHT group was 1.3%; no patients in the primary PCI group experienced major bleeding. Conclusion: PHT can be delivered safely by paramedical staff in regional and rural Australia with good clinical outcomes.

© 2016 Taylor & Francis Group, LLC. Background: Tobacco use and heavy alcohol consumption occur more frequently in socioeconomically disadvantaged groups. Little is known about the sociodemographic and psychosocial factors associated with use of alcohol and tobacco in disadvantaged groups in comparison to low-risk users. Objectives: This study aimed to compare the characteristics of low-risk users with: disadvantaged smokers only; disadvantaged heavy drinkers only; and disadvantaged concurrent smokers and heavy drinkers. Methods: A cross-sectional survey of socioeconomically disadvantaged adult clients attending a community welfare agency assessed tobacco use, alcohol use, demographic, and psychosocial variables. Multivariable analysis using multinomial logistic regression was carried out. Results: The sample consisted of 835 participants; 40% (n = 331) were concurrent users, 31% were smokers only (n = 252), 11% were heavy drinkers only (n = 93), and 18% were low-risk users (n = 149). Compared with those who neither smoked nor consumed alcohol heavily, concurrent users were more likely to be younger, have only some contact with family, have more friends and family who were smokers, have no fixed home address, live alone, and have higher levels of financial stress. Most of these factors were shared by individuals who were smokers only. Factors associated with heavy drinkers only were frequent contact with family and having more friends and family who were smokers. Conclusion: Among those Australians who suffer severe economic hardship, being a concurrent smoker and heavy drinker appears to be associated with more isolated living conditions and financial stress but some contact with family.

Apolipoprotein H (ApoH) is a multi-functional plasma glycoprotein that has been associated with negative health outcomes. ApoH levels have high heritability. We undertook a genome-wide association study of ApoH levels using the largest sample to date and replicated the results in an independent cohort (total N = 1,255). In the discovery phase, a meta-analysis of two cohorts, the Sydney Memory and Ageing Study (Sydney MAS) and the Older Australian Twins Study (OATS) (n = 942) revealed genome-wide significant results in or near the APOH gene on chromosome 17 (top SNP, rs7211380, p = 1 × 10 -11 ). The results were replicated in an independent cohort, the Hunter Community Study (p < 0.002) (n = 313). Conditional and joint analysis (COJO) confirmed the association of the chromosomal 17 region with ApoH levels. The set of independent SNPs identified by COJO explained 23% of the variance. The relationships between the top SNPs and cardiovascular/lipid/cognition measures and diabetes were assessed in Sydney MAS, with suggestive results observed for diabetes and cognitive performance. However, replication of these results in the smaller OATS cohort was not found. This work provides impetus for future research to better understand the contribution of genetics to ApoH levels and its possible impacts on health.

© 2015 Kelly et al.; licensee BioMed Central. Background: Cardiovascular disease and cancer are leading causes of mortality for people with a history of alcohol or other substance use disorders. These chronic diseases share the same four primary behavioural risk factors i.e. excessive alcohol use, smoking, low intake of fruit and vegetables and physical inactivity. In addition to addressing problematic alcohol use, there is the potential for substance abuse treatment services to also address these other behaviours. Healthy Recovery is an 8-session group-based intervention that targets these multiple behavioural health risk factors and was developed specifically for people attending substance abuse treatment. This protocol describes a Cancer Institute NSW funded study that assesses the effectiveness of delivering Healthy Recovery for people who are attending residential alcohol and other substance abuse treatment. Methods/Design: The study uses a stepped wedge randomised controlled design, where randomisation occurs at the service level. Participants will be recruited from residential rehabilitation programs provided by The Australian Salvation Army. All participants who (1) currently smoke tobacco and (2) are expected to be in the residential program for the duration of the 5-week intervention will be asked to participate in the study. Those participants residing at the facilities assigned to the treatment condition will complete Healthy Recovery. The intervention is manual guided and will be delivered over a 5-week period, with participants attending 8 group sessions. All participants will continue to complete The Salvation Army residential program, a predominantly 12-step based, modified therapeutic community. Participants in the control condition will complete treatment as usual. Research staff blind to treatment allocation will complete the primary and secondary outcome assessments at baseline and then at weeks 8, 20 and 32 weeks post intervention. Discussion: This study will provide comprehensive data on the effect of delivering a healthy lifestyle intervention (i.e. Healthy Recovery) within a residential substance abuse setting. If shown to be effective, this intervention can be disseminated within other residential substance abuse programs. Trial registration: Australian and New Zealand Clinical Trials Register (ANZCTR): ACTRN12615000165583. Registered 19 th February 2015.

© 2015 Rifat et al. Background: Bangladesh is one of the 27 high burden countries for multidrug resistant tuberculosis listed by the World Health Organization. Delay in multidrug resistant tuberculosis treatment may allow progression of the disease and affect the attempts to curb transmission of drug resistant tuberculosis. The main objective of this study was to investigate the health system delay in multidrug resistant tuberculosis treatment in Bangladesh and to explore the factors related to the delay. Methods: Information related to the delay was collected as part of a previously conducted case-control study. The current study restricts analysis to patients with multidrug resistant tuberculosis who were diagnosed using rapid diagnostic methods (Xpert MTB/RIF or the line probe assay). Information was collected by face-to-face interviews and through record reviews from all three Government hospitals providing multidrug resistant tuberculosis services, from September 2012 to April 2013. Multivariable regression analysis was performed using Bootstrap variance estimators. Definitions were as follows: Provider delay: time between visiting a provider for first consultation on MDR-TB related symptom to visiting a designated diagnostic centre for testing; Diagnostic delay: time from date of diagnostic sample provided to date of result; Treatment initiation delay: time between the date of diagnosis and date of treatment initiation; Health system delay: time between visiting a provider to start of treatment. Health system delay was derived by adding provider delay, diagnostic delay and treatment initiation delay. Results: The 207 multidrug resistant tuberculosis patients experienced a health system delay of median 7.1 weeks. The health system delay consists of provider delay (median 4 weeks), diagnostic delay (median 5 days) and treatment initiation delay (median 10 days). Health system delay (Coefficient: 37.7; 95 %; CI 15.0-60.4; p 0.003) was associated with the visit to private practitioners for first consultation. Conclusions: Diagnosis time for multidrug resistant tuberculosis was fast using the rapid tests. However, some degree of delay was present in treatment initiation, after diagnosis. The most effective way to reduce health system delay would be through strategies such as engaging private practitioners in multidrug resistant tuberculosis control.

© The Author 2015. Published by Oxford University Press. All rights reserved. Background. People with a history of stroke or heart disease are at increased risk of future stroke; therefore, identification of risk factors by GPs is critical. Objectives. To compare the following among general practice patients with and without a history of stroke or heart disease: (i) self-reported prevalence rates of lifestyle risk factors; (ii) accuracy of GP detection of patient-reported risk factors and (iii) average proportion of patient-reported risk factors detected by GPs. Methods. Consecutive patients attending a participating general practice clinic were invited to participate in a cross-sectional touchscreen survey assessing lifestyle risk factors in 2010-11. The GP of each consenting patient completed a corresponding survey assessing the patient's risk factors. Demographic characteristics of patients and GPs were obtained. Results. Data from 51 GPs and 564 patients were analysed. Patients without a history of stroke or heart disease reported significantly higher rates of smoking (12%) and risky alcohol consumption (56%) than patients with a history of stroke or heart disease (6% and 36%, respectively). Low sensitivity of GP detection of risk factors was found for all risk factors for all patients. Patients with a history of stroke or heart disease have a significantly higher mean proportion of risk factors detected by their GP compared to patients without a history of stroke or heart disease (P = 0.00). Conclusion. Given low sensitivity and specificity of GP detection of risk factors among patients, alternate methods of identification are needed. Research is required to determine strategies to facilitate secondary care of patients with a history of stroke or heart disease by GPs.

© 2015, American Aging Association. Hand grip strength (GS) is a predictor of mortality in older adults and is moderately to highly heritable, but no genetic variants have been consistently identified. We aimed to identify single nucleotide polymorphisms (SNPs) associated with GS in middle-aged to older adults using a genome-wide association study (GWAS). GS was measured using handheld dynamometry in community-dwelling men and women aged 55¿85 from the Hunter Community Study (HCS, N = 2088) and the Sydney Memory and Ageing Study (Sydney MAS, N = 541). Genotyping was undertaken using Affymetrix microarrays with imputation to HapMap2. Analyses were performed using linear regression. No genome-wide significant results were observed in HCS nor were any of the top signals replicated in Sydney MAS. Gene-based analyses in HCS identified two significant genes (ZNF295, C2CD2), but these results were not replicated in Sydney MAS. One out of eight SNPs previously associated with GS, rs550942, located near the CNTF gene, was significantly associated with GS (p = 0.005) in the HCS cohort only. Study differences may explain the lack of consistent results between the studies, including the smaller sample size of the Sydney MAS cohort. Our modest sample size also had limited power to identify variants of small effect. Our results suggest that similar to various other complex traits, many genetic variants of small effect size may influence GS. Future GWAS using larger samples and consistent measures may prove more fruitful at identifying genetic contributors for GS in middle-aged to older adults.

Background: Systematic reviews of high-quality evidence are used to inform policy and practice. To improve community health, the production of such reviews should align with burden of disease. This study aims to assess if the volume of research output from systematic reviews proportionally aligns with burden of disease assessed using percentages of mortality and disability-adjusted life years (DALYs). Methods: A cross-sectional audit of reviews published between January 2012 and August 2013 in the Cochrane Database of Systematic Reviews (CDSR) and Database of Abstracts of Reviews of Effects (DARE) was undertaken. Percentages of mortality and DALYs were obtained from the 2010 Global Burden of Disease study. Standardised residual differences (SRD) based on percentages of mortality and DALYs were calculated, where conditions with SRD of more than or less than three were considered overstudied or understudied, respectively. Results: 1029 reviews from CDSR and 1928 reviews from DARE were examined. There was a significant correlation between percentage DALYs and systematic reviews published in CDSR and DARE databases (CDSR: r=0.68, p=0.001; DARE: r=0.60, p < 0.001). There was no significant correlation between percentage mortality and number of systematic reviews published in either database (CDSR: r=0.34, p=0.14; DARE: r=0.22, p=0.34). Relative to percentage of mortality, mental and behavioural disorders, musculoskeletal conditions and other non-communicable diseases were overstudied. Maternal disorders were overstudied relative to percentages of mortality and DALYs in CDSR. Conclusions: The focus of systematic reviews is moderately correlated with DALYs. A number of conditions may be overstudied relative to percentage of mortality particularly in the context of health and medical reviews.

© 2015 Macmillan Publishers Limited. General cognitive function is substantially heritable across the human life course from adolescence to old age. We investigated the genetic contribution to variation in this important, health- and well-being-related trait in middle-aged and older adults. We conducted a meta-analysis of genome-wide association studies of 31 cohorts (N=53 949) in which the participants had undertaken multiple, diverse cognitive tests. A general cognitive function phenotype was tested for, and created in each cohort by principal component analysis. We report 13 genome-wide significant single-nucleotide polymorphism (SNP) associations in three genomic regions, 6q16.1, 14q12 and 19q13.32 (best SNP and closest gene, respectively: rs10457441, P=3.93 × 10 < sup > -9 < /sup > , MIR2113; rs17522122, P=2.55 × 10 < sup > -8 < /sup > , AKAP6; rs10119, P=5.67 × 10 < sup > -9 < /sup > , APOE/TOMM40). We report one gene-based significant association with the HMGN1 gene located on chromosome 21 (P=1 × 10 < sup > -6 < /sup > ). These genes have previously been associated with neuropsychiatric phenotypes. Meta-analysis results are consistent with a polygenic model of inheritance. To estimate SNP-based heritability, the genome-wide complex trait analysis procedure was applied to two large cohorts, the Atherosclerosis Risk in Communities Study (N=6617) and the Health and Retirement Study (N=5976). The proportion of phenotypic variation accounted for by all genotyped common SNPs was 29% (s.e.=5%) and 28% (s.e.=7%), respectively. Using polygenic prediction analysis, ~1.2% of the variance in general cognitive function was predicted in the Generation Scotland cohort (N=5487; P=1.5 × 10 < sup > -17 < /sup > ). In hypothesis-driven tests, there was significant association between general cognitive function and four genes previously associated with Alzheimer's disease: TOMM40, APOE, ABCG1 and MEF2C.

© 2015 Wiley Publishing Asia Pty Ltd. A cross-sectional survey was conducted in a regional area in Australia to measure nurses' perceptions, practices, and knowledge in regard to providing healthy lifestyle advice to people who are overweight or obese. Responses were compared between geographic regions. Participation was voluntary and anonymous. Of the 79 nurse participants, 68% considered that provision of healthy lifestyle advice was within their scope of practice. Only 28% reported frequently estimating body mass index in the practice setting. Nurses often recommended increasing activity levels (44%), but recommended reducing daily caloric intake less often (25%). Nurses' knowledge about weight management was variable and the proportion of correct answers to knowledge items ranged from 33-99%. Nurses have many opportunities to deliver healthy lifestyle advice in a range of practice settings. The variation in practices and knowledge of nurses indicates a need for improved healthy lifestyle education for undergraduate and practicing nurses.

© 2015 by National Stroke Association. Background: The Age, Blood pressure, Clinical features, Duration of symptoms, Diabetes (ABCD2) score can be used to predict early recurrent stroke risk following Transient ischemic attack (TIA). Given that recurrent stroke risk can be as high as 20% in the first week, international guidelines recommend ''high-risk'' TIAs (ABCD2 .3) be seen by specialist services such as dedicated acute neurovascular clinics within 24 hours. The goal of this study was to examine the associations of both quality of referrals to a specialist acute clinic and of "guideline congruence" of time-to-clinic consultation after TIA/minor stroke. We hypothesized highquality referrals containing key clinical elements would be associated with greater guideline congruence. Methods: A retrospective analysis of referrals to an acute neurovascular clinic within a tertiary care hospital of consecutive patients with TIA/minor stroke. Quality of general practitioner and emergency department referrals was defined on the basis of information content enabling ABCD2-based risk stratification by the clinic triage service. Time-to-clinic consultation was used to define "guideline congruence." Results: Referrals of 148 consecutive eligible patients were reviewed. Sixty-six percent of cases were subsequently neurologist-diagnosed as TIA or minor stroke. Seventy-nine percent were referred by general practitioners. Fifty-three percent of referrals were of high quality, but quality was not associated with guideline congruence. Of the high-risk patients, only 3.6% were seen at the clinic within 24 hours of index event and 31.3% within 24 hours of referral. Conclusions: Current guidelines are pathophysiologically logical and evidence based, but are difficult to implement. Improving quality of primary-secondary communication by improved referral quality is unlikely to improve guideline compliance. Alternative strategies are needed to reduce recurrent stroke risk after TIA/minor stroke.

© 2015 Elsevier Inc. Objective: There is a growing body of literature examining the clustering of health risk behaviours, but little consensus about which risk factors can be expected to cluster for which sub groups of people. This systematic review aimed to examine the international literature on the clustering of smoking, poor nutrition, excess alcohol and physical inactivity (SNAP) health behaviours among adults, including associated socio-demographic variables. Method: A literature search was conducted in May 2014. Studies examining at least two SNAP risk factors, and using a cluster or factor analysis technique, or comparing observed to expected prevalence of risk factor combinations, were included. Results: Fifty-six relevant studies were identified. A majority of studies (81%) reported a 'healthy' cluster characterised by the absence of any SNAP risk factors. More than half of the studies reported a clustering of alcohol with smoking, and half reported clustering of all four SNAP risk factors. The methodological quality of included studies was generally weak to moderate. Males and those with greater social disadvantage showed riskier patterns of behaviours; younger age was less clearly associated with riskier behaviours. Conclusion: Clustering patterns reported here reinforce the need for health promotion interventions to target multiple behaviours, and for such efforts to be specifically designed and accessible for males and those who are socially disadvantaged.

© 2015 Noble et al. Background: Indigenous Australians are a socially disadvantaged group who experience significantly poorer health and a higher prevalence of modifiable health behaviours than other Australians. Little is known about the clustering of h ealth risks among Indigenous Australians. The aims of this study were to describe the clustering of key health risk factors, such as smoking, physical inactivity and alcohol consumption, and socio-demographics associated with clusters, among a predominantly Aboriginal sample. Methods: Participants (n = 377) attending an Aboriginal Community Controlled Health Service (ACCHS) in regional/rural New South Wales, Australia, in 2012-2013 completed a self-report touch screen health risk survey. Clusters were identified using latent class analysis. Results: Cluster 1 ('low fruit/vegetable intake, lower risk'; 51 %) consisted of older men and women; Cluster 2 ('risk taking'; 22 %) included younger unemployed males with a high prevalence of smoking, risky alcohol, and illicit drug use. Cluster 3 ('inactive, overweight, depressed'; 28 %) was characterised by younger to mid aged women likely to have experienced emotional or physical violence. Conclusions: If future research identifies similar stable clusters of health behaviours for this population, intervention approaches targeting these clusters of risk factors should be developed and tested for Aboriginal and Torres Strait Islander Australians.

METHODS: We conducted genome-wide association studies for paragraph or word list delayed recall in 19 cohorts from the Cohorts for Heart and Aging Research in Genomic Epidemiology consortium, comprising 29,076 dementia- and stroke-free individuals of European descent, aged =45 years. Replication of suggestive associations (p < 5 × 10 -6 ) was sought in 10,617 participants of European descent, 3811 African-Americans, and 1561 young adults. RESULTS: rs4420638, near APOE, was associated with poorer delayed recall performance in discovery (p = 5.57 × 10 -10 ) and replication cohorts (p = 5.65 × 10 -8 ). This association was stronger for paragraph than word list delayed recall and in the oldest persons. Two associations with specific tests, in subsets of the total sample, reached genome-wide significance in combined analyses of discovery and replication (rs11074779 [HS3ST4], p = 3.11 × 10 -8 , and rs6813517 [SPOCK3], p = 2.58 × 10 -8 ) near genes involved in immune response. A genetic score combining 58 independent suggestive memory risk variants was associated with increasing Alzheimer disease pathology in 725 autopsy samples. Association of memory risk loci with gene expression in 138 human hippocampus samples showed cis-associations with WDR48 and CLDN5, both related to ubiquitin metabolism. CONCLUSIONS: This largest study to date exploring the genetics of memory function in ~40,000 older individuals revealed genome-wide associations and suggested an involvement of immune and ubiquitin pathways.

© 2015 American Academy of Pain Medicine. Objective: With escalating opioid prescribing come individual and public health harms. To inform quality improvement measures, understanding of opioid prescribing is essential. We aimed to establish consultation-level prevalence and associations of opioid prescribing. Design: A cross-sectional secondary analysis from a longitudinal multisite cohort study of general practitioner (GP) vocational trainees: "Registrar Clinical Encounters in Training." Setting: Four of Australia's seventeen GP Regional Training Providers, during 2010-13. Subjects: GP trainees. Methods: Practice and trainee demographic data were collected as well as patient, clinical and educational data of 60 consecutive consultations of each trainee, each training term. Outcome factors were any opioid analgesic prescription and initial opioid analgesic prescription for a specific problem for the first time. Results: Overall, 645 trainees participated. Opioids comprised 4.3% prescriptions provided for 3.8% of patients. Most frequently prescribed were codeine (39.9%) and oxycodone (33.4%). Prescribing was for acute pain (29.3%), palliative care (2.6%) or other indications (68.1%). Most prescribing involved repeat prescriptions for pre-existing problems (62.7% of total). Other associations included older patients; prescriber and patient male gender; Aboriginal/Torres Strait Islander status; rural and disadvantaged locations; longer consultations; and generation of referrals, follow-up, and imaging requests. Opioid initiation was more likely for new patients with new problems, but otherwise associations were similar. Trainees rarely reported addiction risk-mitigation strategies. Conclusions: Most opioids were prescribed as maintenance therapy for non-cancer pain. Demographic associations with opioid analgesic prescribing resemble those presenting for opioid dependency treatment. Our findings should inform measures by regulators and medical educators supporting multimodal pain management.

© 2015 Kay-Lambkin et al. Background: Depression and binge drinking behaviours are common clinical problems, which cause substantial functional, economic and health impacts. These conditions peak in young adulthood, and commonly co-occur. Comorbid depression and binge drinking are undertreated in young people, who are reluctant to seek help via traditional pathways to care. The iTreAD project (internet Treatment for Alcohol and Depression) aims to provide and evaluate internet-delivered monitoring and treatment programs for young people with depression and binge drinking concerns. Methods: Three hundred sixty nine participants will be recruited to the trial, and will be aged 18-30 years will be eligible for the study if they report current symptoms of depression (score 5 or more on the depression subscale of the Depression Anxiety Stress Scale) and concurrent binge drinking practices (5 or more standard drinks at least twice in the prior month). Following screening and online baseline assessment, participants are randomised to: (a) online monthly self-assessments, (b) online monthly self-assessments¿+¿12-months of access to a 4 week online automated cognitive behaviour therapy program for binge drinking and depression (DEAL); or (c) online monthly assessment¿+¿DEAL¿+¿12-months of access to a social networking site (Breathing Space). Independent, blind follow-up assessments occur at 26, 39, 52 and 64-weeks post-baseline. Discussion: The iTreAD project is the first randomised controlled trial combining online cognitive behaviour therapy, social networking and online monitoring for young people reporting concerns with depression and binge drinking. These treatments represent low-cost, wide-reach youth-appropriate treatment, which will have significantly public health implications for service design, delivery and health policy for this important age group. Trial registration: Australian and New Zealand Clinical Trials Registry ACTRN12614000310662. Date registered 24 March 2014.

© 2014 - IOS Press and the authors. All rights reserved. There are a growing number of large cohorts of older persons with genome-wide genotyping data available, but APOE is not included in any of the common microarray platforms. We compared directly measured APOE genotypes with those imputed using microarray data and the '1000 Genomes' dataset in a sample of 320 Caucasians. We find 90% agreement for e2/e3/e4 genotypes and 93% agreement for predicting e4 status, yielding kappa values of 0.81 and 0.84, respectively. More stringent thresholds around allele number estimates can increase this agreement to 90-97% and kappas of 0.90-0.93.

The American Psychiatric Association estimates that 3 to 7 per cent of all school aged children are diagnosed with attention deficit hyperactivity disorder (ADHD). Even after correcting for general cognitive ability, numerous studies report a negative association between ADHD and educational achievement. With polygenic scores we examined whether genetic variants that have a positive influence on educational attainment have a protective effect against ADHD. The effect sizes from a large GWA meta-analysis of educational attainment in adults were used to calculate polygenic scores in an independent sample of 12-year-old children from the Netherlands Twin Register. Linear mixed models showed that the polygenic scores significantly predicted educational achievement, school performance, ADHD symptoms and attention problems in children. These results confirm the genetic overlap between ADHD and educational achievement, indicating that one way to gain insight into genetic variants responsible for variation in ADHD is to include data on educational achievement, which are available at a larger scale. © 2014 Wiley Periodicals, Inc.

Elevated serum urate concentrations can cause gout, a prevalent and painful inflammatory arthritis. By combining data from >140,000 individuals of European ancestry within the Global Urate Genetics Consortium (GUGC), we identified and replicated 28 genome-wide significant loci in association with serum urate concentrations (18 new regions in or near TRIM46, INHBB, SFMBT1, TMEM171, VEGFA, BAZ1B, PRKAG2, STC1, HNF4G, A1CF, ATXN2, UBE2Q2, IGF1R, NFAT5, MAF, HLF, ACVR1B-ACVRL1 and B3GNT4). Associations for many of the loci were of similar magnitude in individuals of non-European ancestry. We further characterized these loci for associations with gout, transcript expression and the fractional excretion of urate. Network analyses implicate the inhibins-activins signaling pathways and glucose metabolism in systemic urate control. New candidate genes for serum urate concentration highlight the importance of metabolic control of urate production and excretion, which may have implications for the treatment and prevention of gout. © 2013 Nature America, Inc.
