Obstructive sleep apnea (OSA) is a common disorder associated with multiple adverse health consequences and its prevalence is increasing in parallel with rising obesity trends. Early support for ethnic differences in OSA prevalence and severity has been derived from studies of relatively homogenous ethnic groups. However, between-study comparisons are problematic given differing methodologies. Recent large inter-ethnic studies examining different ethnic populations using standardized protocols support the notion that Chinese have an increased OSA prevalence and severity compared to those of European descent. Although the evidence is less clear, some data suggest that Hispanic/Mexican Americans also show higher rates of OSA, while OSA prevalence in African Americans is not dissimilar to that of populations of European ancestry. Of the anatomical traits underlying differences in OSA prevalence and severity between ethnic groups (i.e., obesity, fat distribution, and craniofacial structure) obesity appears to be the most important. The effect of ethnicity on non-anatomical factors (i.e., upper airway muscle responsiveness, arousal threshold, and loop gain) responsible for OSA severity and potentially prevalence is currently unknown and needs further research.

Results for selected BLVR procedures indicate they can provide significant and clinically meaningful short-term (up to one year) improvements in health outcomes, but this was at the expense of increased adverse events. The currently available evidence is not sufficient to assess the effect of BLVR procedures on mortality. These findings are limited by the lack of long-term follow-up data, limited availability of cost-effectiveness data, significant heterogeneity in results, presence of skew and high CIs, and the open-label character of a number of the studies.

VT appears to be a safe and well-tolerated opportunistic treatment for inpatient smokers who have related chronic disease. Based on the proven efficacy of varenicline from outpatient studies and our recent inpatient evidence, we suggest it be considered as part of standard care in the hospital setting.

Background Severe community‐acquired pneumonia (SCAP) has high mortality and morbidity. Aims To describe the epidemiology and microbiology of SCAP in Central Australia. Methods A retrospective epidemiological study describing the characteristics, incidence rates (IR) and microbiological aetiology of SCAP in Central Australia. Adult patients admitted to Alice Springs Hospital Intensive Care Unit (ICU) between 2011 and 2014 that fitted the Infectious Diseases Society of America and American Thoracic Society definition of SCAP were included. Medical records were reviewed and compared between indigenous and non‐indigenous patients. Primary outcomes were incidence rate and microbiological aetiology of SCAP. Secondary outcomes were 30‐day mortality, and ICU and hospital length of stay (LoS). Results A total of 185 patents were included (156 indigenous; 29 non‐indigenous). The overall SCAP IR per 1000 person‐years was 3.24 (3.75 indigenous; 1.87 non‐indigenous) with an IR difference of 2.71 after adjustment (P < 0.001). Those aged ≥50 years had an IR 74.8% higher than those younger. Male IR was 50% higher than females. There was a significant difference between indigenous and non‐indigenous groups for age (48 vs 64 years), but not for 30‐day mortality (7.7% vs 10.3%), ICU LoS (4.8 vs 4.6 days) and hospital LoS (10.9 vs 15.1 days) respectively. Likely causative pathogen(s) were identified in 117 patients; Streptococcus pneumoniae was the most common pathogen (28.2%), followed by Haemophilus influenzae (19.7%), Influenza A/B (16.2%) and Staphylococcus aureus (14.5%). Conclusion A high incidence of SCAP was observed in Central Australia, disproportionately affecting the indigenous population. Prevention strategies are imperative, as well as early identification of SCAP and appropriate empiric antibiotic regimens.

IntroductionVarenicline tartrate is superior for smoking cessation to other tobacco cessation therapies by 52 weeks, in the outpatient setting. We aimed to evaluate the long-term (104 week) efficacy following a standard course of inpatient-initiated varenicline tartrate plus Quitline-counselling compared to Quitline-counselling alone. MethodsAdult patients (n = 392, 20-75 years) admitted with a smoking-related illnesses to one of three hospitals, were randomised to receive either 12-weeks of varenicline tartrate (titrated from 0.5mg daily to 1mg twice-daily) plus Quitline-counselling, (n = 196) or Quitline-counselling alone, (n = 196), with continuous abstinence from smoking assessed at 104 weeks. ResultsA total of 1959 potential participants were screened for eligibility between August 2008 and December 2011. The proportion of participants who remained continuously abstinent (intention-to-treat) at 104 weeks were significantly greater in the varenicline tartrate plus counselling arm (29.2% n = 56) compared to counselling alone (18.8% n = 36; p = 0.02; odds ratio 1.78; 95%CI 1.10 to 2.86, p = 0.02). Twenty-two deaths occurred during the 104 week study
