Trends in mental health, non-suicidal self-harm and suicide attempts in 16-24-year old students and non-students in England, 2000-2014
There are concerns about high levels of mental ill-health amongst university students, but little is known about the mental health of students compared to non-students over time. Using data on young people (16-24) from three UK National Psychiatric Morbidity Surveys (2000, 2007, and 2014), we found no evidence that the overall prevalence of common mental disorder (CMD), suicide attempts, or non-suicidal self-harm (NSSH) differed between students and non-students, although there was an indication that CMDs rose markedly in female students between 2007 and 2014. A rise in NSSH is apparent in both students and non-students
Variations in the hospital management of self harm in adults in England: observational study
More than 140 000 people present to hospital after an
episode of self harm each year in England and Wales.
Improving the general hospital management of these
people is a key area in preventing suicide. Although
professional consensus has been reached on how self
harm services should be organised and delivered,
wide variations in care delivery have been reported in
two regions in England. Using a nationally
representative sample, we investigated the variation in
services and delivery of care for self harm patients in
hospitals in England
Associations of height, leg length, and lung function with cardiovascular risk factors in the Midspan Family Study
<b>Background</b>: Taller people and those with better lung function are at reduced risk of coronary heart disease (CHD). Biological mechanisms for these associations are not well understood, but both measures may be markers for early life exposures. Some studies have shown that leg length, an indicator of pre-pubertal nutritional status, is the component of height most strongly associated with CHD risk. Other studies show that height-CHD associations are greatly attenuated when lung function is controlled for. This study examines (1) the association of height and the components of height (leg length and trunk length) with CHD risk factors and (2) the relative strength of the association of height and forced expiratory volume in one second (FEV1) with risk factors for CHD.
<b>Subjects and methods</b>: Cross sectional analysis of data collected at detailed cardiovascular screening examinations of 1040 men and 1298 women aged 30–59 whose parents were screened in 1972–76. Subjects come from 1477 families and are members of the Midspan Family Study.
<b>Setting</b>: The towns of Renfrew and Paisley in the West of Scotland.
<b>Results</b>: Taller subjects and those with better lung function had more favourable cardiovascular risk factor profiles, associations were strongest in relation to FEV1. Higher FEV1 was associated with lower blood pressure, cholesterol, glucose, fibrinogen, white blood cell count, and body mass index. Similar, but generally weaker, associations were seen with height. These associations were not attenuated in models controlling for parental height. Longer leg length, but not trunk length, was associated with lower systolic and diastolic blood pressure. Longer leg length was also associated with more favourable levels of cholesterol and body mass index than trunk length.
<b>Conclusions</b>:These findings provide indirect evidence that measures of lung development and pre-pubertal growth act as biomarkers for childhood exposures that may modify an individual's risk of developing CHD. Genetic influences do not seem to underlie height-CHD associations
Suicide epidemics: The impact of newly emerging methods on overall suicide rates - A time trends study
Background: The impact of newly emerging, popular suicide methods on overall rates of suicide has not previously been investigated systematically. Understanding these effects may have important implications for public health surveillance. We examine the emergence of three novel methods of suicide by gassing in the 20 th and 21 st centuries and determine the impact of emerging methods on overall suicide rates. Methods. We studied the epidemic rises in domestic coal gas (1919-1935, England and Wales), motor vehicle exhaust gas (1975-1992, England and Wales) and barbecue charcoal gas (1999-2006, Taiwan) suicide using Poisson and joinpoint regression models. Joinpoint regression uses contiguous linear segments and join points (points at which trends change) to describe trends in incidence. Results: Epidemic increases in the use of new methods of suicide were generally associated with rises in overall suicide rates of between 23% and 71%. The recent epidemic of barbecue charcoal suicides in Taiwan was associated with the largest rise in overall rates (40-50% annual rise), whereas the smallest rise was seen for car exhaust gassing in England and Wales (7% annual rise). Joinpoint analyses were only feasible for car exhaust and charcoal burning suicides; these suggested an impact of the emergence of car exhaust suicides on overall suicide rates in both sexes in England and Wales. However there was no statistical evidence of a change in the already increasing overall suicide trends when charcoal burning suicides emerged in Taiwan, possibly due to the concurrent economic recession. Conclusions: Rapid rises in the use of new sources of gas for suicide were generally associated with increases in overall suicide rates. Suicide prevention strategies should include strengthening local and national surveillance for early detection of novel suicide methods and implementation of effective media guidelines and other appropriate interventions to limit the spread of new methods. © 2011 Thomas et al; licensee BioMed Central Ltd.published_or_final_versio
Collective Oscillations of Vortex Lattices in Rotating Bose-Einstein Condensates
The complete low-energy collective-excitation spectrum of vortex lattices is
discussed for rotating Bose-Einstein condensates (BEC) by solving the
Bogoliubov-de Gennes (BdG) equation, yielding, e.g., the Tkachenko mode
recently observed at JILA. The totally symmetric subset of these modes includes
the transverse shear, common longitudinal, and differential longitudinal modes.
We also solve the time-dependent Gross-Pitaevskii (TDGP) equation to simulate
the actual JILA experiment, obtaining the Tkachenko mode and identifying a pair
of breathing modes. Combining both the BdG and TDGP approaches allows one to
unambiguously identify every observed mode.Comment: 5 pages, 4 figure

Suicide and self-harm in Britain: researching risk and resilience using UK surveys
Aim The main aim of this study was to raise awareness of surveys that could be used to inform self-harm and suicide prevention work. We asked:
What UK survey datasets are available for research?
What aspects of people’s lives are associated with self-harm and attempted suicide?
How do statistical findings resonate with people’s lived experience? What implications do they see?
Findings Survey analyses revealed that risk factors for self-harm are wide ranging and include:
Mental health
Physical health and health behaviours
Social relationships
Stressful events
Employment and financial circumstances
Identity and demographics
Many different factors are independently associated with self-harm. There is a dose relationship, with more exposure to a factor linked with increased risk. Risks are cumulative that is, exposure to multiple factors is associated with greater risk.
Through facilitated consultation, men with lived experience, bereaved family members, and practitioners identified recommendations for responding to suicidal distress in men. These related to the following three main areas:
1. Recognising need: who is ‘ill enough’?
Permission - men said that they often did not know they were entitled to help
Ask - people who outwardly appear to be functioning may not be
Persistence - ask and offer help more than once.
2. Facilitating access: right words, time and place
What is available - support is needed with ongoing stress as well as for crises
Find the words - men wanted examples of how to ask for help
Allow time - employers expect recovery to be swift, some men felt rushed to come off medications or were discharged from services they still needed.
3. Adjusting delivery: equal engagement
Power - some were uncomfortable with service dynamics, preferring peer support
Every service contact counts - negative contacts had particular impact
Safe spaces - may be different for men and women.
Methods
There were three strands of work:
Secondary analysis of nine survey series, spanning more than twenty years
Linkage of 144,000 survey participants to information on whether they were alive in 2013 and whether they had taken their own life
Facilitated consultation, through depth interviews with people with lived experience
The efficacy of problem-solving treatments after deliberate self-harm: meta-analysis of randomized controlled trials with respect to depression, hopelessness and improvement in problems
Background. Brief problem-solving therapy is regarded as a pragmatic treatment for deliberate self-harm (DSH) patients. A recent meta-analysis of randomized controlled trials (RCTs) evaluating this approach indicated a trend towards reduced repetition of DSH but the pooled odds ratio was not statistically significant. We have now examined other important outcomes using this procedure, namely depression, hopelessness and improvement in problems.
Method. Six trials in which problem-solving therapy was compared with control treatment were identified from an extensive literature review of RCTs of treatments for DSH patients. Data concerning depression, hopelessness and improvement in problems were extracted. Where relevant statistical data (e.g. standard deviations) were missing these were imputed using various statistical methods. Results were pooled using meta-analytical procedures.
Results. At follow-up, patients who were offered problem-solving therapy had significantly greater improvement in scores for depression (standardized mean difference =[minus sign]0·36; 95% CI [minus sign]0·61 to [minus sign]0·11) and hopelessness (weighted mean difference =[minus sign]3·2; 95% CI [minus sign]4·0 to [minus sign]2·41), and significantly more reported improvement in their problems (odds ratio = 2·31; 95% CI 1·29 to 4·13), than patients who were in the control treatment groups.
Conclusions. Problem-solving therapy for DSH patients appears to produce better results than control treatment with regard to improvement in depression, hopelessness and problems. It is desirable that this finding is confirmed in a large trial, which will also allow adequate testing of the impact of this treatment on repetition of DSH
Prevalence and associated harm of engagement in self-Asphyxial behaviours ('choking game') in young people:A systematic review
OBJECTIVE: To assess the prevalence of engagement in self-asphyxial (risk-taking) behaviour (SAB) (‘choking game’) and associated morbidity and mortality in children and young people up to age 20. DESIGN: Systematic literature review. SEARCH STRATEGY: Electronic database search of MEDLINE, Embase, PsycINFO, CINAHL, PubMed, Web of Science Core Collection, BIOSIS citation index and the Cochrane register with no language or date limits applied. References of key papers were reviewed, and experts were contacted to identify additional relevant papers. ELIGIBILITY CRITERIA: Systematic reviews, cross-sectional, cohort and case–control studies, and case reports examining SAB with regard to individuals aged 0–20 years, without explicitly stated autoerotic, suicidal or self-harm intentions were included. RESULTS: Thirty-six relevant studies were identified, and SAB was reported in 10 countries. In North America, France and Colombia, awareness of SAB ranged from 36% to 91% across studies/settings, and the median lifetime prevalence of engagement in SAB was 7.4%. Six studies identified the potential for SAB to be associated with engagement in other risk behaviours. Ninety-nine fatal cases were reported. Of the 24 cases described in detail, most occurred when individuals engaged in SAB alone and used a ligature. CONCLUSIONS: The current evidence on SAB among young people is limited, and stems predominantly from North America and France. Awareness of SAB among young people is high, and engagement varies by setting. Further research is needed to understand the level of risk and harm associated with SAB, and to determine the appropriate public health response
