Statistical analyses are important for real-world validation of theoretical model predictions. In this article, a statistical analysis of real data shows empirically how thermal resistance, thermal mass, building design, season and external air temperature collectively affect indoor air temperature. A simple, four-point, diurnal, temperature-by-time profile is used to summarise daily thermal performance and is used as the response variable for the analysis of performance. The findings from the statistical analysis imply that, at least for moderate climates, the best performing construction/design will be one in which insulation and thermal mass arrangements can be dynamically altered to suit weather and season.

Background: Convective warming is effective in maintaining core temperature under anesthesia. It may increase evaporative water loss (EWL). If significant, further investigation of warming modifications to minimize this impact would be warranted. Objectives: To quantify EWL in two groups of children (warmed and nonwarmed) having surgical procedures under anesthesia. Methods: We performed an observational study of well children having general anesthesia for elective surgical procedures lasting =60 min. They were recruited sequentially to each of three age groups: 1-12 months, 13 months - 5 years, and 5-12 years - with each age group divided into convectively warmed (43°C) and nonwarmed (21°C) subgroups. Evaporative heat loss (EHL) was calculated from accurate measurement of net EWL during the surgical period. Results: Sixty children were studied. As a percentage of body mass, mean EWLs were 0.29 (warmed) and 0.09 (nonwarmed). Using an ANCOVA model, only procedure duration had a significant impact and explained why the extended procedural time in some convectively warmed children led to higher mean EWLs for that group. For the nonwarmed group, the mean Tcore drop was 1.27°C with a contribution from EWL of 0.6°C over ~70 min. Conclusions: Within the age range 1 month-12 years, EHL is not significantly influenced by convective heating under anesthesia. There is no thermal advantage in exploring technique modifications such as humidifying the warming air. Previous estimates of the contribution of EHL to total heat loss in anesthetized children may require revision.

2014Stockings EAL, Bowman JA, Baker AL, Terry M, Clancy R, Wye PM, et al., 'Impact of a postdischarge smoking cessation intervention for smokers admitted to an inpatient psychiatric facility: A randomized controlled trial', Nicotine and Tobacco Research, 16 1417-1428 (2014) [C1]

Introduction: Persons with a mental disorder smoke at higher rates and suffer disproportionate tobacco-related burden compared with the general population. The aim of this study was to determine if a smoking cessation intervention initiated during a psychiatric hospitalization and continued postdischarge was effective in reducing smoking behaviors among persons with a mental disorder. Methods: A randomized controlled trial was conducted at an Australian inpatient psychiatric facility. Participants were 205 patient smokers allocated to a treatment as usual control (n = 101) or a smoking cessation intervention (n = 104) incorporating psychosocial and pharmacological support for 4 months postdischarge. Follow-up assessments were conducted at 1 week, 2, 4, and 6 months postdischarge and included abstinence from cigarettes, quit attempts, daily cigarette consumption, and nicotine dependence. Results: Rates of continuous and 7-day point prevalence abstinence did not differ between treatment conditions at the 6-month follow-up; however, point prevalence abstinence was significantly higher for intervention (11.5%) compared with control (2%) participants at 4 months (OR = 6.46, p = .01). Participants in the intervention condition reported significantly more quit attempts (F[1, 202.5] = 15.23, p = .0001), lower daily cigarette consumption (F[4, 586] = 6.5, p < .001), and lower levels of nicotine dependence (F[3, 406] = 8.5, p < .0001) compared with controls at all follow-up assessments. Conclusions: Postdischarge cessation support was effective in encouraging quit attempts and reducing cigarette consumption up to 6 months postdischarge. Additional support strategies are required to facilitate longer-term cessation benefits for smokers with a mental disorder.
