Ten years psychosocial outcomes among adolescents following suicide attempts – early recurrence and psychosocial outcomes

ObjectivesA suicide attempt (SA) is a major risk factor of recurrent SA in adolescence and may be associated with psychological or social problems in the future. REPEATERS is a longitudinal study which examines the long-term psychosocial outcome of adolescents following attempted suicide. It focuses on the impact of early recurrence (i.e., within the first year of the index SA) – data which is, in fact, poorly documented.MethodsTen years after the index SA, a self-reporting questionnaire was sent to all adolescents who had attempted suicide and were followed up by the CHRU (Regional University Hospital Centre) de Nancy, France, between 1994 and 2003 and their parents. The purpose of this questionnaire was to assess psychosocial outcomes. Data concerning SA were collected retrospectively.ResultsAfter ten years, 146 of the 309 adolescents who had attempted suicide and were participating in the study had responded: 90% lived with a partner and 41% had children. The mean (SD) current emotional life of suicide attempt survivors scored 7.3 (2.3) on a scale of 0 to 10. Compared to the general population of the same age, responders felt more depressed than their peers (29% vs. less than 8% of males and 20% of females), had more suicidal thoughts (14% vs. 5%), and had more SAs (27% vs. 0.3%). Moreover, the risk of recurrence over the ten year period was associated with suicide recurrence in the first year after the index SA (odds ratio [OR] = 2.3; 95% confidence interval [CI] = 1.1–4.9) and with a lower level of education at ten years (OR = 0.37; 95% CI = 0.19–0.45).ConclusionsAlthough a favorable outcome was reported ten years after the event for the majority of adolescents who had attempted suicide, some with a lower level of education were nevertheless at increased risk of recurrence and depression. Post-intervention strategies are therefore essential in order to evaluate risk factors which may persist if not taken into consideration.     

lncRNA-FTX与脑胶质瘤病人预后的相关性分析

目的 探讨长链非编码RNA（lncRNA）FTX表达水平与脑胶质瘤病人预后的相关性。方法 前瞻性收集2016年1月~2018年1月手术切除的脑胶质瘤88例（46例获得瘤旁组织），采用实时逆转录PCR检测lncRNA FTX表达水平，以脑胶质瘤组织lncRNA FTX表达水平均值为界分为高表达组（n=57）和低表达组（n=31）。术后随访3年，主要观察指标为无进展生存期、总生存期。结果 脑胶质瘤组织lncRNA FTX表达水平[（7.54±2.15）]明显高于瘤旁组织[（2.65±0.69）；P<0.001]。多因素Cox比例回归风险模型分析显示，lncRNA FTX高表达是脑胶质瘤生存预后不良的独立危险因素（RR=1.589；95% CI 1.004~2.515；P=0.048）。生存曲线分析显示，高表达组无进展生存期（15.10个月）和总生存期（20.24个月）较低表达组（分别为18.96和25.53个月）明显缩短（P<0.05）。结论 脑胶质瘤lncRNA FTX呈高表达，与病人不良生存预后有关。

The personal limitations checklist: human factors insights from air accidents to reduce intraoperative harm

High Reliability Organisations (HRO), including healthcare and aviation, have a common focus on risk management. The human element is a ‘weak link’ which may result in accidents or adverse events taking place. Surgeons and other healthcare professionals can learn from aviation's rigorous approach to the role of human factors (HF) in such events, and how we can minimise them. Air Accident Investigation Branch (AAIB) reports show that fatal accidents are frequently caused by pilots flying outside their own personal limits, those of the aircraft or environment. Similarly, patient morbidity or mortality may occur if surgeons work outside personal their capability, with poor procedure selection and patient optimisation, or with a team or theatre environment not suited to the procedure. We introduce the personal limitations checklist – a tool adapted from aviation that allows surgeons to define their limits in advance of any decision to operate, and develop critical self-reflection. It also allows management of patient expectations, shared decision making, and flattening of team hierarchy. The minimum skills, patient characteristics, team and theatre resources for any given procedure to proceed are defined. If the surgeon is ‘out of limits’, redressing these factors, seeking additional assistance, or thorough patient consenting may be required for the safe conduct of the procedure. We explore external pressures that could cause a surgeon to exceed both personal and organisational limits.
