There have been concerns about the increased use of helium and nitrogen gas as a suicide mechanism in Australia.

National Coronial Information System data were used to investigate gas-specific suicides in Australia over the period 2006-2017. Characteristics were compared between helium or nitrogen, carbon monoxide and seven other gases.

Gas inhalation accounted for 10% (3,103/31,002) of all suicide deaths in Australia between 2006 and 2017. The mean age of individuals who died by suicide was 47.6 years (SD 16.9, R 14-97) and 83.3% were male. The number of gas suicides declined over the study period (IRR=0.96). The fall was associated with a 47% decline in carbon monoxide suicides (IRR=0.93). There was an increase in deaths due to argon (IRR=1.60) and nitrogen (IRR=1.27). Compared to individuals using other non-carbon monoxide gases, individuals who died by suicide from helium or nitrogen were significantly more likely to be older, have a physical illness and/or disability, have contacted a euthanasia group and have accessed instructional material and purchased gas online.

Suicides by carbon monoxide decreased between 2006 and 2017 alongside an increase in argon and nitrogen gas use – particularly among older adults. The ease of access to these gases points to new targets for means restriction. Implications for public health Identifying the types of gases used in suicide deaths and emerging trends may enable targeted interventions that could potentially reduce access.

Herein, the first example of isolated Rh atoms on ordered PtBi nanoplates (PtBi-Rh1 ) by atomic galvanic replacement, and their subsequent transformation into a tensile-strained Pt-Rh single-atom alloy (PtBi@PtRh1 ) via electrochemical dealloying are presented. Benefiting from the Rh1 -tailored Pt (110) surface with tensile strain, the PtBi@PtRh1 nanoplates exhibit record-high and all-round superior electrocatalytic performance including activity, selectivity, stability, and anti-poisoning ability toward ethanol oxidation in alkaline electrolytes. Density functional theory calculations reveal the synergism between effective Rh1 and tensile strain in boosting the adsorption of ethanol and key surface intermediates and the CC bond cleavage of the intermediates. The facile synthesis of the tensile-strained single-atom alloy provides a novel strategy to construct model nanostructures, accelerating the development of highly efficient electrocatalysts.

The objective of this study was to evaluate an Aboriginal-led diabetes lifestyle program catering to urban Aboriginal people in an Aboriginal organisation.

Mixed-methods study that employed routinely collected physiological data and audio-recorded focus group sessions. Physiological data were analysed using a multi-level model to account for participant clustering. Qualitative data were subject to thematic analysis.

Participants were overwhelmingly positive about the program. They lost weight and improved their diastolic blood pressure and glycaemic control; however, it was the feelings of belonging and optimism about their ability to improve their health that they most valued. Qualitative analysis revealed three main themes. These were ‘With the Mob’, ‘For the Mob’ and ‘Program Elements. The strengths of the program lay in its indigeneity, low-cost and easy-to-prepare diet, and cultural and communication skills of the director.

Recommendations for improvement included educating participants on the pathophysiology of diabetes, the refinement of online elements and the introduction of face-to-face group exercise. Implications for public health Programs of this nature should be expanded and evaluated longitudinally with multiple cohorts.

National smoking prevalence is decreasing among Aboriginal and Torres Strait Islander people. In remote areas, Aboriginal and Torres Strait Islander smoking prevalence remains higher than in nonremote areas and is not improving.

We analysed data from 539 daily and weekly smokers from remote areas who completed baseline surveys at either Wave 1 (April 2012-October 2013) or Wave 2 (August 2013-August 2014), including 157 from Wave 1 who also completed Wave 2, from the Talking About The Smokes project. We assessed associations between baseline predictor measures and having made any quit attempt in the past year and, among those who did, having sustained the last quit attempt for one month or more.

More smokers had made a quit attempt if they were younger or reported being unable to buy essentials due to money spent on smokes, being more stressed, having several pro-quitting motivations and attitudes, having an effective smoke-free home, or being encouraged to quit by a health professional or by family/friends. Of these, more had sustained their last quit attempt for one month or more if they reported being more socially advantaged, no smoking-induced deprivation, being less dependent, chewing pituri or an having effective smoke-free home.

Health staff should consider the quite different factors associated with starting and then sustaining a quit attempt. NE 52-QQ57 nmr SO WHAT? Our findings support continued attention in remote areas on smoke-free homes and health staff providing regular encouragement to all smokers to quit and more use of smokers’ friends and family for support.
