Reviewing past and present consent practices in unplanned obstetric interventions: an eye towards the future.

Many first-time mothers (primiparous) within UK National Health Service (NHS) settings require an obstetric intervention to deliver their babies safely. While the antepartum period allows time for conversations about consent for planned interventions, such as elective caesarean section, current practice is that, in emergencies, consent is addressed in the moments before the intervention takes place. This paper explores whether there are limitations on the validity of consent offered in time-pressured and emotionally charged circumstances, specifically concerning emergency obstetric interventions. Using the legal framework of the Mental Capacity Act, Montgomery v. Lanarkshire Health Board (2015) and McCulloch v Forth Valley Health Board (2023), we argue that while women have the capacity to consent during labour, their autonomy is best supported by providing more information about instrumental delivery (ID) during the antepartum period. This conclusion is supported by some national guidelines, including those developed by the Royal College of Obstetricians and Gynaecologists, but not all. Further, we examine the extent to which these principles are upheld in modern-day practice. Data suggest there is relatively little antepartum information provision regarding ID within NHS settings, and that primiparous women do not report a thorough understanding of ID before labour. Based on these results, and bearing in mind the pressures under which NHS obstetric services currently operate, we recommend further research into patient and clinician perceptions of the consent process for ID. Pending these results, we discuss possible modes of information delivery in future practice.

An ex-vivo assessment of a new single probe triple modality (Trilogy) lithotripter.

INTRODUCTION AND OBJECTIVES: This Swiss LithoClast® Trilogy lithotrite is a new lithotrite for percutaneous nephrolithotomy (PCNL). It has four modifiable settings; impact, frequency, ultrasound and suction. We aim to determine the optimal device settings for the fastest stone clearance. MATERIALS AND METHODS: Kidney stone phantoms were made with Begostone in a powder to water ratio (15:3-15:6). Complete stone clearance (seconds) was calculated and impact and frequency were adjusted and repeated N = 3. Intra renal pressure (IRP) was then measured in a porcine kidney model. RESULTS: Stone phantoms with physical properties similar to struvite were cleared best with 100% impact and frequency of 12 Hz. Both uric acid stone phantoms and calcium phosphate stone phantoms were cleared most efficiently with an impact of 30% and a frequency of 4 Hz. The mean time to clear uric acid stone phantoms was 83 s versus 217 s for calcium phosphate stone phantoms. Similarly, for calcium oxalate stone phantoms, an impact of 30% and a frequency of 4 Hz was associated with the fastest clearance time, mean 204 s. However, the differences between 4, 8 and 12 Hz were not statistically significant. At a suction level of 60% or higher, IRP became negative. CONCLUSION: These results indicate that stone phantoms of hard kidney stones are cleared more efficiently at lower impact and frequency settings. With regard to suction, a setting of ≤ 50% appears to be the optimal setting.

The Her Tribe and His Tribe Aboriginal-Designed Empowerment Programs.

This study documents evaluation of the Her Tribe and His Tribe Aboriginal-designed empowerment pilot programs. The programs were designed to support Victorian Aboriginal people to strengthen mental health, social and emotional wellbeing, community connection, and to reduce psychological distress. A second aim was to explore participants' experiences of the programs, including the feasibility and acceptability of the evaluation component. Her Tribe ran for 16 weeks and His Tribe for 12 weeks. In total, 43 women and 26 men completed assessments at pre- and post-program completion, and 17 and 10, respectively, participated in yarning circles at the 6-month follow up. For both programs, there were significant increases in participants' access to personal strengths and resources, relationship-community-cultural strengths and resources, and decreases in psychological distress. These changes were associated with small to moderate effects that were maintained at the 6-month follow up. There was a significant increase in aerobic fitness for female but not male participants, and no significant changes in weight for either group. Participants described a range of benefits from the programs, including positive elements and areas for improvement. They also viewed the evaluation as feasible and acceptable, and the findings of value. The outcomes from both pilot programs provide evidence that Aboriginal-designed programs, with a focus on physical and cultural activities, can help to strengthen mental health and wellbeing, community connection, and reduce psychological distress in Victorian Aboriginal communities.

A systematic review of magnetic versus conventional ureteric stents for short term ureteric stenting.

Ureteric stents play an essential role in urology. However, patients can suffer a range of stent-related symptoms with stent in situ and during removal. Conventional ureteric stents are removed using a flexible cystoscopy, whereas magnetic stents may be rapidly removed with a smaller catheter-like retrieval device. The primary aim of this systematic review was to compare the morbidity including pain associated with conventional versus magnetic ureteric stents. The secondary aim was cost comparison. Searches were performed across databases, including Medline, Scopus, Embase and Cochrane. This review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search from the 5 databases returned a total of 358 articles. After duplicates were removed as well as the inclusion and exclusion criteria applied, a total of 6 studies were included in the final review. Ureteric Stent Symptoms Questionnaire (USSQ) and Visual Analogue Score (VAS) were used in most of the studies. All the studies reported that magnetic ureteric stents resulted in a reduction in the pain on the removal of magnetic ureteric stents, and no statistically significant difference with indwelling ureteric stents. Furthermore, majority of the studies reported a reduction in the cost associated with magnetic ureteric stents. There is no significant difference in pain from indwelling ureteric stents. There is a reduction in pain with the removal of magnetic ureteric stents compared to conventional removal via cystoscopy and an associated reduction in cost.

Changes in the age young Aboriginal and Torres Strait Islander people start smoking, 2002-2015.

OBJECTIVES: To analyse trends in smoking initiation and prevalence among young Aboriginal and Torres Strait Islander people (Indigenous people) to identify which stages of adolescence and young adulthood prevention activities should target. METHODS: Secondary analysis of 'daily smoking' and 'never smoked' responses from Indigenous people aged 15 years and older in five national Indigenous surveys from 2002 to 2014-15, and of initiation age among those aged 18 years and older in 2004-05 and 2012-13. RESULTS: Smoking prevalence among 15-24-year-olds declined significantly between 2002 and 2014-15, falling 14 percentage points (95%percnt; confidence interval [CI] 8, 21) from 45%percnt; to 31%percnt;. The greatest decline was among 18-19-year-olds, with a decrease of 17 percentage points (95% CI 4, 29) from 48%percnt; to 31%percnt;. The proportion of 15-24-year-olds who had never smoked increased significantly, by 12 percentage points (95%percnt; CI 6, 18) from 44%percnt; in 2002 to 56%percnt; in 2014-15. Between 2004-05 and 2012-13, the proportion of 18-24-year-old smokers who had started daily smoking before the age of 18 years declined significantly, down 8 percentage points (95%percnt; CI 2, 15) from 84%percnt; to 76%percnt;. In 2012-13, 24%percnt; of smokers aged 18-24 years started daily smoking after age 18, half (49%percnt;) started between 15 and 18 years, and around a quarter started before age 15. CONCLUSIONS: There have been significant declines in smoking prevalence among young Indigenous people between 2002 and 2014-15 as fewer take up smoking. Smoking initiation occurs over a wide age range. The majority of daily smokers started before the age of 18; however, initiation may be delayed until early adulthood for an increasing number. The challenge for tobacco prevention is to reach young people in early adolescence and continue to reinforce smoke-free intentions into young adulthood.

Do stress, life satisfaction, depression and alcohol use predict quitting among Aboriginal and Torres Strait Islander smokers?

OBJECTIVE: To examine whether baseline measures of stress, life satisfaction, depression and alcohol use predict making or sustaining quit attempts in a national cohort of Aboriginal and Torres Strait Islander smokers. METHODS: We analysed data from the nationally representative quota sample of 1,549 Aboriginal and Torres Strait Islander adults who reported smoking at least weekly in the Talking About The Smokes baseline survey (April 2012-October 2013) and the 759 who completed a follow-up survey a year later (August 2013-August 2014). RESULTS: More smokers who reported negative life satisfaction, feeling depressed, higher stress or drinking heavily less often than once a week at baseline made a quit attempt between the baseline and follow-up surveys. In contrast, of these smokers who had made quit attempts between surveys, more who reported higher stress were able to sustain abstinence for at least one month; other associations were inconclusive. Conclusions and implications for public health: Health staff and Aboriginal and Torres Strait Islander smokers need not see being more stressed as an obstacle to quitting among Aboriginal and Torres Strait Islander people. Health staff should emphasise the benefits to mental health that come with successfully quitting smoking.

Predictors and reasons for starting and sustaining quit attempts in a national cohort of Aboriginal and Torres Strait Islander smokers.

INTRODUCTION AND AIMS: The national prevalence of daily smoking among the Aboriginal and Torres Strait Islander population is 39% but falling. We explore factors associated with starting and sustaining quit attempts, and reasons given for quitting. DESIGN AND METHODS: We analysed data from the nationally representative quota sample of 759 Aboriginal and Torres Strait Islander adults who reported smoking at least weekly in the Talking About The Smokes baseline survey (April 2012-October 2013) who completed a follow-up survey a year later (August 2013-August 2014). RESULTS: Having made more quit attempts, more recent quit attempts in the past, motivational attitudes, having been encouraged to quit by a health professional and having noticed tobacco advertising were associated with making a quit attempt between surveys. Having made longer quit attempts in the past, non-daily smoking and quit self-efficacy were associated with sustaining abstinence. But neither having made more quit attempts in the past nor dependence was associated with sustaining abstinence. Health concerns, price and setting an example to children were the most common reasons given by smokers and ex-smokers for quitting. DISCUSSION AND CONCLUSIONS: Different factors predict making and sustaining quit attempts among Aboriginal and Torres Strait Islander smokers. We need to rethink current messages that just encourage Aboriginal and Torres Strait Islander smokers to keep making quit attempts by increasing motivation to quit, as motivation and making more quit attempts does not predict eventual success. We could focus more on increasing smokers' confidence that they can successfully quit.

Social networks and quitting in a national cohort of Australian Aboriginal and Torres Strait Islander smokers.

INTRODUCTION AND AIMS: Health behaviours, such as smoking and quitting, spread person-to-person through social networks. We explore how social networks are associated with making and sustaining quit attempts for at least 1 month among Aboriginal and Torres Strait Islander smokers. DESIGN AND METHODS: We analysed data from the nationally representative quota sample of 759 Aboriginal and Torres Strait Islander adults who reported smoking at least weekly in Talking About The Smokes baseline survey (April 2012-October 2013) who completed a follow-up survey a year later (August 2013-August 2014). RESULTS: At baseline, 41% of smokers reported that all of their five closest family or friends smoked, but 62% reported that family or friends had provided encouragement to quit. Fewer smokers with other adult smokers in their household at baseline made a quit attempt between surveys (OR 0.63, 95% CI 0.45-0.87). Fewer smokers who had made an attempt between surveys sustained abstinence for at least 1 month if all of their five closest friends smoked (OR 0.60, 95% CI 0.37-0.97). Perceived support to quit in your social network was associated with making and sustaining a quit attempt. DISCUSSION AND CONCLUSIONS: Exposure to smoking in the social networks of Aboriginal and Torres Strait Islander smokers is an obstacle to quitting, but there is also considerable support for quitting from within these same social networks. Health staff could consider encouraging smokers to draw on the few non-smokers within their social networks as role models to increase their confidence in quitting.
