    前刺柏是一种属于豆科植物的观赏植物。它含有毒素白蛋白,叫Abrin,在它的所有部分。然而,种子以压碎的形式食用时毒性更大。因葡萄籽中毒而死亡的情况很少见。我们正在报告一例37岁女性自杀摄入压碎的前科瑞斯种子的案例。她向医院提出了多次呕吐和腹泻的投诉。她用液体推注复苏,然后洗胃和活性炭,提到了我们的三级医院,她带着头晕的表情,腹痛,血性腹泻,和上腹压痛.在随后的日子里,她产生了改变的感觉,肾功能衰竭,和电解质不平衡。她被保守地管理。血液检查显示白细胞计数升高,尿素和肌酐水平升高,和肝酶升高。她在摄取种子五天后死亡。在尸检检查中,脑和肺充血和水肿。腹膜腔含有约500mL的稻草色液体。肺部出现瘀斑出血,心,和肝脏表面。胃肠道粘膜出血性,肝脏显示脂肪变性,肾脏显示出皮质髓质交界处的充血和模糊。组织病理学,肺部显示轻度充血伴肺泡水肿,肝脏显示坏死伴脂肪变性,肾脏表现为急性肾小管坏死。毒理学筛查为abrin阳性。这种情况不仅突显了abrusprecatorius中毒后的罕见死亡,而且还突显了该植物的毒性。
    Abrus precatorius is an ornamental plant that belongs to the Leguminoceae family. It contains toxalbumin, named abrin, in all of its parts. However, the seeds are more toxic when consumed in crushed form. Deaths due to abrus seed poisoning are rare. We are reporting a case of suicidal ingestion of crushed abrus precatorius seeds by a 37-year-old female. She presented to the hospital with complaints of multiple episodes of vomiting and diarrhea. She was resuscitated with fluid boluses, followed by a stomach wash and activated charcoal, and referred to our tertiary hospital, where she presented with giddiness, abdominal pain, bloody diarrhea, and epigastric tenderness. On subsequent days, she developed altered sensorium, renal failure, and electrolyte imbalance. She was managed conservatively. Blood investigation revealed elevated leucocyte count, increased urea and creatinine levels, and elevated liver enzymes. She died five days after ingesting the seeds. On autopsy examination, the brain and lungs were congested and edematous. The peritoneal cavity contained around 500mL of straw-colored fluid. Petechial hemorrhages were present over the lungs, heart, and liver surfaces. The mucosa of the gastrointestinal tract was hemorrhagic, the liver showed steatosis, and the kidneys showed congestion and obscuration of the corticomedullary junction. Histopathologically, the lungs showed mild congestion with alveolar edema, the liver showed necrosis with steatosis, and the kidney showed acute tubular necrosis. The toxicology screening was positive for abrin. This case highlights not only the rare fatality following abrus precatorius poisoning but also the toxic nature of this plant.

    BACKGROUND: The war in Syria has displaced over 6.8 million people, more than any other conflict since the Second World War. As a result, Syrian asylum seekers and refugees have experienced several life-changing events, resulting in high rates of anxiety, depression, posttraumatic stress disorder, and suicidal ideation (SI). To address the treatment gap and reduce the burden of help-seeking, a web-based intervention to reduce SI developed for general populations was culturally adapted for and with Syrian asylum seekers and refugees in the United Kingdom. The study revealed the importance of understanding their lived experience with migration and the acculturative process in providing treatment for SI. This study will now assess the feasibility and acceptability of the culturally adapted intervention for this population.
    OBJECTIVE: The first phase of the study will include recruiting participants and delivering the web-based intervention (1) to assess the feasibility of meeting recruitment goals and recruitment rates and (2) to assess the feasibility of outcome measures. The second phase of the study will include one-to-one semistructured interviews (1) to assess the suitability of the culturally adapted intervention in terms of recruitment and adherence rates and barriers and facilitators to engagement and (2) to assess the acceptability of the intervention in terms of its cultural relevance and appropriateness.
    METHODS: This is a protocol for a single-group, noncontrolled, mixed methods feasibility and acceptability study of a culturally adapted web-based intervention to reduce SI for Syrian asylum seekers and refugees in the United Kingdom. The study will assess the feasibility of recruitment goals, recruitment rates, adherence rates, and outcome measures using individual participant tracking forms, which will be analyzed quantitatively. The suitability and acceptability of the intervention will be assessed using one-to-one semistructured interviews with 12 participants who completed the intervention, which will be analyzed qualitatively.
    RESULTS: Recruitment began in February 2024 and will run until 30 participants are recruited to the study or until the end of July 2024. Thus far, 19 participants have provided informed consent, 16 were eligible and enrolled, and 12 have completed a postintervention interview. No data have been analyzed. The study, including the write-up period, is expected to end in December 2024.
    CONCLUSIONS: Despite experiencing several stressors related to forced displacement and high rates of mental health issues, access to treatment is still limited for Syrian asylum seekers and refugees in the United Kingdom. To address the treatment gap and reduce the burden of help-seeking, a web-based intervention to reduce SI was culturally adapted in collaboration with Syrian asylum seekers and refugees in the United Kingdom. This study will now assess the feasibility and acceptability of the intervention and culturally appropriate recruitment strategies.

    背景:在儿童和青少年中,自我伤害的思想和行为(SITB)正在急剧增加。危机支持旨在提供即时的精神保健,风险缓解,以及对经历SITB和急性心理健康困扰的人的干预。数字心理健康干预措施(DMHI)已成为面对面护理的可访问和有效替代方案;然而,大多数不为SITB的儿童和青少年提供危机支持或持续护理。
    目的:为出现SITB的儿童和青少年提供数字危机支持和精神卫生保健的发展,这项研究旨在(1)描述参与数字危机应对服务的SITB儿童和青少年的特征,(2)在整个护理过程中,比较患有SITB的儿童和青少年的焦虑和抑郁症状与没有SITB的儿童和青少年的焦虑和抑郁症状,和(3)建议未来的步骤,为提交SITB的儿童和青少年实施数字危机支持和精神保健。
    方法:这项回顾性研究使用儿童和青少年(1-17岁;N=2161)参与儿科协同护理DMHI的数据进行。在每个现场会议期间评估SITB患病率。对于在现场表演中展示SITB的儿童和青少年,一个快速的危机支持小组提供了基于证据的危机支持服务。大约每月完成一次评估以测量焦虑和抑郁症状的严重程度。人口统计,心理健康症状,并将出现SITB的儿童和青少年(有SITB的组)与没有SITB的儿童和青少年(没有SITB的组)的心理健康症状的变化进行了比较。
    结果:与没有SITB的组(1977/2161,91.49%)相比,SITB组(184/2161,8.51%)主要由青少年(107/184,58.2%)和女性儿童和青少年(118/184,64.1%)组成.在基线,与没有SITB的组相比,SITB组的焦虑和抑郁症状更严重.从DMHI的精神保健之前到之后,两组儿童和青少年焦虑症状改善率无差异(SITB组:54/70,77%vs无SITB组:367/440,83.4%;χ21=1.2;P=.32),抑郁症状改善率无差异(SITB组:58/72,81%vs无SITB组:255/313,81.5%;χ21=0;P=.99)。两组在使用DMHI治疗期间,焦虑(t80.20=1.37;P=.28)和抑郁(t83.75=-0.08;P=.99)症状的症状严重程度变化也没有差异。
    结论:这项研究表明,参与协同护理DMHI与经历SITB的儿童和青少年的心理健康结局改善有关。这些结果为儿童和青少年在危机支持和心理保健中使用儿童DMHIs提供了初步见解。从而解决儿童和青少年急性心理健康危机的公共卫生问题。
    BACKGROUND: Self-injurious thoughts and behaviors (SITBs) are increasing dramatically among children and adolescents. Crisis support is intended to provide immediate mental health care, risk mitigation, and intervention for those experiencing SITBs and acute mental health distress. Digital mental health interventions (DMHIs) have emerged as accessible and effective alternatives to in-person care; however, most do not provide crisis support or ongoing care for children and adolescents with SITBs.
    OBJECTIVE: To inform the development of digital crisis support and mental health care for children and adolescents presenting with SITBs, this study aims to (1) characterize children and adolescents with SITBs who participate in a digital crisis response service, (2) compare anxiety and depressive symptoms of children and adolescents presenting with SITBs versus those without SITBs throughout care, and (3) suggest future steps for the implementation of digital crisis support and mental health care for children and adolescents presenting with SITBs.
    METHODS: This retrospective study was conducted using data from children and adolescents (aged 1-17 y; N=2161) involved in a pediatric collaborative care DMHI. SITB prevalence was assessed during each live session. For children and adolescents who exhibited SITBs during live sessions, a rapid crisis support team provided evidence-based crisis support services. Assessments were completed approximately once a month to measure anxiety and depressive symptom severity. Demographics, mental health symptoms, and change in the mental health symptoms of children and adolescents presenting with SITBs (group with SITBs) were compared to those of children and adolescents with no SITBs (group without SITBs).
    RESULTS: Compared to the group without SITBs (1977/2161, 91.49%), the group with SITBs (184/2161, 8.51%) was mostly made up of adolescents (107/184, 58.2%) and female children and adolescents (118/184, 64.1%). At baseline, compared to the group without SITBs, the group with SITBs had more severe anxiety and depressive symptoms. From before to after mental health care with the DMHI, the 2 groups did not differ in the rate of children and adolescents with anxiety symptom improvement (group with SITBs: 54/70, 77% vs group without SITBs: 367/440, 83.4%; χ21=1.2; P=.32) as well as depressive symptom improvement (group with SITBs: 58/72, 81% vs group without SITBs: 255/313, 81.5%; χ21=0; P=.99). The 2 groups also did not differ in the amount of change in symptom severity during care with the DMHI for anxiety (t80.20=1.37; P=.28) and depressive (t83.75=-0.08; P=.99) symptoms.
    CONCLUSIONS: This study demonstrates that participation in a collaborative care DMHI is associated with improved mental health outcomes in children and adolescents experiencing SITBs. These results provide preliminary insights for the use of pediatric DMHIs in crisis support and mental health care for children and adolescents presenting with SITBs, thereby addressing the public health issue of acute mental health crisis in children and adolescents.

    关于抑郁症患者的γ-氨基丁酸(GABA)变构调节剂睡眠辅助药物的数据有限,失眠,自杀意念(SI)。
    这项次要分析研究了年龄与失眠的关系以及年龄对抑郁症自杀患者唑吡坦缓释剂(唑吡坦-ER)治疗失眠的影响。先前的报告发现,唑吡坦-ER的添加在8周内促进了失眠和SI的抑郁门诊患者的整体失眠严重程度的显著降低,但是在这里我们报告早期之间的差异,中间,晚失眠症
    此二次分析检查了三个早期,中间,汉密尔顿抑郁量表(HRSD)的晚期失眠项目及其与年龄和唑吡坦-ER治疗反应性的关系。一百零三名重度抑郁症患者,SI,失眠症患者接受了开放标签的5-羟色胺再摄取抑制剂,睡前服用1:1随机分配接受唑吡坦-ER或安慰剂.结果:基线时年龄较大与中晚期失眠恶化有关,但不是早期失眠。随后用唑吡坦-ER治疗可改善早期和中期失眠,但不是晚期失眠。
    这些发现与已知的一般人群和抑郁症门诊患者中与年龄相关的睡眠时间提前以及短半衰期GABA变构调节剂睡眠辅助的预期效果一致。通过暗示,当关注晚期失眠时,药物治疗抑郁症患者失眠的处方者应考虑替代唑吡坦-ER.试验注册号:ClinicalTrials.gov标识符:NCT01689909。
    UNASSIGNED: There are limited data regarding gamma-aminobutyric acid (GABA) allosteric modulator sleep-aid medications in persons with depression, insomnia, and suicidal ideation (SI).
    UNASSIGNED: This secondary analysis examined the relationship of age to insomnia and the impact of age on the treatment of insomnia with zolpidem extended-release (zolpidem-ER) in depressed suicidal patients. A prior report found that the addition of zolpidem-ER promoted significantly superior reductions in global severity of insomnia in depressed outpatients with insomnia and SI over 8 weeks, but here we report the differences among early, middle, and late insomnia.
    UNASSIGNED: This secondary analysis examined the three early, middle, and late insomnia items of the Hamilton Rating Scale for Depression (HRSD) and their relationship to age and responsiveness to treatment with zolpidem-ER. One hundred and three patients with major depression, SI, and insomnia received open-label serotonin reuptake inhibitors and were randomly allocated 1:1 to receive zolpidem-ER or placebo at bedtime. Results: Older age at baseline was associated with worse middle and late insomnia, but not with early insomnia. Subsequent treatment with zolpidem-ER produced superior improvement in early and middle insomnia, but not late insomnia.
    UNASSIGNED: These findings are consistent with the known age-related advancement of sleep timing in the general population and depressed outpatients and with the expected effects of a short half-life GABA allosteric modulator sleep aid. By implication, prescribers of pharmacologic treatment of insomnia in depressed patients should consider an alternative to zolpidem-ER when late insomnia is a concern.Trial registration number: ClinicalTrials.gov Identifier: NCT01689909.

    背景:自杀是全球死亡的主要原因。新闻报道准则旨在遏制不安全报道的影响;然而,在新闻报道中自杀的框架可能因情况和死者的性别等重要特征而有所不同。
    目的:本研究旨在研究新闻媒体对自杀报道使用污名化或荣耀化的语言进行陷害的程度,以及性别和自杀情况在这种陷害方面的差异。
    方法:我们分析了200篇有关自杀的新闻文章,并应用经过验证的自杀污名量表来识别污名化和荣耀化的语言。我们用2个广泛使用的指标来评估语言相似性,余弦相似性和互信息得分,使用基于机器学习的大型语言模型。
    结果:男性自杀的新闻报道比女性自杀的报道更类似于污名化(P<.001)和美化(P=.005)语言。考虑到自杀的情况,互信息得分表明,在使用污名化或美化语言的性别差异最明显的文章归因于法律(0.155),关系(0.268),或心理健康问题(0.251)为原因。
    结论:语言差异,按性别,在报告自杀时使用污名化或美化语言可能会加剧自杀差异。
    BACKGROUND: Suicide is a leading cause of death worldwide. Journalistic reporting guidelines were created to curb the impact of unsafe reporting; however, how suicide is framed in news reports may differ by important characteristics such as the circumstances and the decedent\'s gender.
    OBJECTIVE: This study aimed to examine the degree to which news media reports of suicides are framed using stigmatized or glorified language and differences in such framing by gender and circumstance of suicide.
    METHODS: We analyzed 200 news articles regarding suicides and applied the validated Stigma of Suicide Scale to identify stigmatized and glorified language. We assessed linguistic similarity with 2 widely used metrics, cosine similarity and mutual information scores, using a machine learning-based large language model.
    RESULTS: News reports of male suicides were framed more similarly to stigmatizing (P<.001) and glorifying (P=.005) language than reports of female suicides. Considering the circumstances of suicide, mutual information scores indicated that differences in the use of stigmatizing or glorifying language by gender were most pronounced for articles attributing legal (0.155), relationship (0.268), or mental health problems (0.251) as the cause.
    CONCLUSIONS: Linguistic differences, by gender, in stigmatizing or glorifying language when reporting suicide may exacerbate suicide disparities.

    背景:由于人工智能(AI)的最新进展,大型语言模型(LLM)已经成为各种语言相关任务的强大工具,包括情绪分析,以及提供者与患者互动的总结。然而,在危机预测领域,对这些模型的研究有限。
    目的:本研究旨在评估LLM的性能,特别是OpenAI的GPT-4,在预测当前和未来的精神健康危机事件时,使用患者在国家远程医疗平台的用户之间的摄入量提供的信息。
    方法:从Brightside远程医疗平台的特定摄入问题中提取去识别患者提供的数据,包括主要投诉,对于140名表示自杀意念(SI)的患者,另外120名患者后来在治疗过程中出现SI计划。在同一时间段内随机选择的200名从未认可SI的患者也获得了类似的数据。6名Brightside高级临床医生(3名心理学家和3名精神科医生)接受了患者自我报告的主诉和自我报告的自杀未遂史,但对未来的治疗过程和包括SI在内的其他报告症状视而不见。他们被问到一个简单的是/否问题,关于他们对SI与计划的认可的预测以及他们对预测的信心水平。GPT-4提供了类似的信息,并要求回答相同的问题,使我们能够直接比较人工智能和临床医生的表现。
    结果:总体而言,临床医生在确定SI时的平均精度(0.698)高于GPT-4(0.596)与计划(n=140)。单独使用主诉时无SI(n=200),而GPT-4的敏感性(0.621)高于临床医生的平均水平(0.529)。增加自杀未遂史增加了临床医生的平均敏感度(0.590)和精确度(0.765),同时提高GPT-4灵敏度(0.590),但降低GPT-4精度(0.544)。在预测具有计划的未来SI(n=120)与无SI(n=200)时,性能相对下降,仅针对临床医生(平均灵敏度=0.399;平均精度=0.594)和GPT-4(灵敏度=0.458;精度=0.482)。增加自杀未遂史可以提高临床医生的表现(平均灵敏度=0.457;平均精度=0.687)和GPT-4(灵敏度=0.742;精度=0.476)。
    结论:GPT-4采用简单的即时设计,在一些指标上产生的结果接近受过训练的临床医生。在这种模型可以在临床环境中试用之前,必须做其他工作。该模型应该进行安全检查的偏见,因为有证据表明LLM可以使他们训练的基础数据的偏见永存。我们相信,LLM有望在摄入时增强对高风险患者的识别,并有可能为患者提供更及时的护理。
    背景:
    BACKGROUND: Due to recent advances in artificial intelligence, large language models (LLMs) have emerged as a powerful tool for a variety of language-related tasks, including sentiment analysis, and summarization of provider-patient interactions. However, there is limited research on these models in the area of crisis prediction.
    OBJECTIVE: This study aimed to evaluate the performance of LLMs, specifically OpenAI\'s generative pretrained transformer 4 (GPT-4), in predicting current and future mental health crisis episodes using patient-provided information at intake among users of a national telemental health platform.
    METHODS: Deidentified patient-provided data were pulled from specific intake questions of the Brightside telehealth platform, including the chief complaint, for 140 patients who indicated suicidal ideation (SI), and another 120 patients who later indicated SI with a plan during the course of treatment. Similar data were pulled for 200 randomly selected patients, treated during the same time period, who never endorsed SI. In total, 6 senior Brightside clinicians (3 psychologists and 3 psychiatrists) were shown patients\' self-reported chief complaint and self-reported suicide attempt history but were blinded to the future course of treatment and other reported symptoms, including SI. They were asked a simple yes or no question regarding their prediction of endorsement of SI with plan, along with their confidence level about the prediction. GPT-4 was provided with similar information and asked to answer the same questions, enabling us to directly compare the performance of artificial intelligence and clinicians.
    RESULTS: Overall, the clinicians\' average precision (0.7) was higher than that of GPT-4 (0.6) in identifying the SI with plan at intake (n=140) versus no SI (n=200) when using the chief complaint alone, while sensitivity was higher for the GPT-4 (0.62) than the clinicians\' average (0.53). The addition of suicide attempt history increased the clinicians\' average sensitivity (0.59) and precision (0.77) while increasing the GPT-4 sensitivity (0.59) but decreasing the GPT-4 precision (0.54). Performance decreased comparatively when predicting future SI with plan (n=120) versus no SI (n=200) with a chief complaint only for the clinicians (average sensitivity=0.4; average precision=0.59) and the GPT-4 (sensitivity=0.46; precision=0.48). The addition of suicide attempt history increased performance comparatively for the clinicians (average sensitivity=0.46; average precision=0.69) and the GPT-4 (sensitivity=0.74; precision=0.48).
    CONCLUSIONS: GPT-4, with a simple prompt design, produced results on some metrics that approached those of a trained clinician. Additional work must be done before such a model can be piloted in a clinical setting. The model should undergo safety checks for bias, given evidence that LLMs can perpetuate the biases of the underlying data on which they are trained. We believe that LLMs hold promise for augmenting the identification of higher-risk patients at intake and potentially delivering more timely care to patients.

    背景:在远程医疗服务越来越多地用于前诊的时代,需要准确的自杀风险检测。使用人工智能分析的声乐特征现在证明能够检测自杀风险,其准确性优于传统的基于调查的方法。建议一种有效和经济的方法来确保持续的患者安全。
    目的:本系统评价旨在确定哪些声音特征在区分自杀风险较高的患者与其他队列相比表现最好,并确定用于得出每个特征的系统的方法学规范和结果分类的准确性。
    方法:通过Ovid搜索MEDLINE,Scopus,计算机和应用科学完成,CADTH,WebofScience,ProQuest论文和论文A&I,澳大利亚在线政策,Mednar于1995年至2020年进行,并于2021年进行了更新。入选标准是没有语言的人类参与者,年龄,或设置限制;随机对照研究,观察性队列研究,和论文;使用某种声音质量衡量标准的研究;使用经过验证的自杀风险衡量标准,与其他风险较低的个体相比,个体被评估为自杀风险较高。使用非随机研究工具中的偏倚风险评估偏倚风险。在报告声音质量的平均测量值的任何地方,都使用随机效应模型荟萃分析。
    结果:搜索产生了1074个独特的引文,其中30例(2.79%)通过全文筛选。共有21项研究涉及1734名参与者,符合所有纳入标准。大多数研究(15/21,71%)通过VanderbiltII数据库(8/21,38%)或Silverman和Silverman感知研究记录数据库(7/21,33%)获取参与者。在区分高自杀风险和比较队列方面表现最佳的候选声音特征包括语音时间模式(中位数准确率为95%),功率谱密度子带(中值精度90.3%),和梅尔频率倒谱系数(中值准确度80%)。随机效应荟萃分析用于比较14%(3/21)的研究中嵌套的22个特征,这证明了第一和第二共振峰内频率的显着标准化平均差(标准化平均差在-1.07和-2.56之间)和抖动值(标准化平均差=1.47)。在43%(9/21)的研究中,偏倚风险评估为中度,而在其余研究中(12/21,57%),偏倚风险被评估为高.
    结论:尽管在所审查的研究中普遍存在几个关键的方法学问题,使用声音特征来检测自杀风险的升高是有希望的,特别是在新颖的环境中,如远程医疗或会话代理。
    背景:PROSPERO国际系统评价前瞻性注册CRD420200167413;https://www.crd.约克。AC.uk/prospro/display_record.php?ID=CRD42020167413。
    BACKGROUND: In an age when telehealth services are increasingly being used for forward triage, there is a need for accurate suicide risk detection. Vocal characteristics analyzed using artificial intelligence are now proving capable of detecting suicide risk with accuracies superior to traditional survey-based approaches, suggesting an efficient and economical approach to ensuring ongoing patient safety.
    OBJECTIVE: This systematic review aimed to identify which vocal characteristics perform best at differentiating between patients with an elevated risk of suicide in comparison with other cohorts and identify the methodological specifications of the systems used to derive each feature and the accuracies of classification that result.
    METHODS: A search of MEDLINE via Ovid, Scopus, Computers and Applied Science Complete, CADTH, Web of Science, ProQuest Dissertations and Theses A&I, Australian Policy Online, and Mednar was conducted between 1995 and 2020 and updated in 2021. The inclusion criteria were human participants with no language, age, or setting restrictions applied; randomized controlled studies, observational cohort studies, and theses; studies that used some measure of vocal quality; and individuals assessed as being at high risk of suicide compared with other individuals at lower risk using a validated measure of suicide risk. Risk of bias was assessed using the Risk of Bias in Non-randomized Studies tool. A random-effects model meta-analysis was used wherever mean measures of vocal quality were reported.
    RESULTS: The search yielded 1074 unique citations, of which 30 (2.79%) were screened via full text. A total of 21 studies involving 1734 participants met all inclusion criteria. Most studies (15/21, 71%) sourced participants via either the Vanderbilt II database of recordings (8/21, 38%) or the Silverman and Silverman perceptual study recording database (7/21, 33%). Candidate vocal characteristics that performed best at differentiating between high risk of suicide and comparison cohorts included timing patterns of speech (median accuracy 95%), power spectral density sub-bands (median accuracy 90.3%), and mel-frequency cepstral coefficients (median accuracy 80%). A random-effects meta-analysis was used to compare 22 characteristics nested within 14% (3/21) of the studies, which demonstrated significant standardized mean differences for frequencies within the first and second formants (standardized mean difference ranged between -1.07 and -2.56) and jitter values (standardized mean difference=1.47). In 43% (9/21) of the studies, risk of bias was assessed as moderate, whereas in the remaining studies (12/21, 57%), the risk of bias was assessed as high.
    CONCLUSIONS: Although several key methodological issues prevailed among the studies reviewed, there is promise in the use of vocal characteristics to detect elevations in suicide risk, particularly in novel settings such as telehealth or conversational agents.

    目的:分析青少年重度抑郁障碍(MDD)伴自杀和自伤行为(SSIB)的相关影响因素。
    方法:采用便利抽样法,选取2022年2月至2023年7月期间该院精神科收治的299名MDD青少年。根据是否存在SSIB,将参与者分为SSIB组(n=110)和非SSIB组(n=189),并对相关指标进行收集和比较。
    结果:患者在第一次SSIB时的年龄范围为10至18岁,平均年龄13.30±1.74岁。最常见的受伤部位是下臂和手腕(42.13%),最常见的伤害是割伤,占患者总数的40.00%。最常见的自我伤害类型因性别而异(X2=17.798,P=0.006);对于男性,打人是最常见的,对于女性来说,切割是最常见的。在51.41%的患者中,从最初的想法到实际的SSIB提交之间的时间少于5分钟.艾森克人格问卷的得分,Barratt冲动量表,巴斯-佩里侵略问卷,症状检查表-90(所有P<0.001),和健康风险行为量表(67.47±12.59vs.与非SSIB组相比,SSIB组41.58±11.36,t=9.587,P<0.001)显着增加。此外,生活质量总分(11.36±4.32vs.与非SSIB组相比,SSIB组降低了16.43±5.64,t=5.496,P<0.001)。
    结论:青少年MDD患者的SSIB与多种因素有关,包括冲动,侵略性,人格特质,QOL,心理健康水平。
    OBJECTIVE: To analyse the related influencing factors of adolescent major depressive disorder (MDD) with suicidal and self-injurious behaviour (SSIB).
    METHODS: A total of 299 adolescents with MDD who were admitted to the psychiatric department of the hospital between February 2022 and July 2023 were selected using the convenience sampling method. The participants were divided into the SSIB group (n = 110) and the non-SSIB group (n = 189) according to whether SSIB was present, and related indicators were collected and compared.
    RESULTS: The patients\' ages at the time of their first SSIB ranged from 10 to 18 years old, with a mean age of 13.30 ± 1.74 years. The most commonly injured parts were the lower arm and wrist (42.13%), and the most common injury was cutting, accounting for 40.00% of the total patients. The most common type of self-injury differed by sex (X2 = 17.798, P = 0.006); for men, hitting was the most common, and for women, cutting was the most common. In 51.41% of the patients, the period between the initial thought and the actual committing of the SSIB was less than 5 minutes. The scores of the Eysenck Personality Questionnaire, the Barratt Impulsivity Scale, the Buss-Perry Aggression Questionnaire, the Symptom Checklist-90 (all P < 0.001), and the health-risk behaviour scale (67.47 ± 12.59 vs. 41.58 ± 11.36, t = 9.587, P < 0.001) were significantly increased in the SSIB group compared with the non-SSIB group. In addition, the total score of quality of life (QOL) (11.36 ± 4.32 vs. 16.43 ± 5.64, t = 5.496, P < 0.001) was decreased in the SSIB group compared with the non-SSIB group.
    CONCLUSIONS: The SSIB of adolescent patients with MDD is related to various factors, including impulsiveness, aggressiveness, personality traits, QOL, and mental health level.

    人们越来越关注使用亚硝酸钠(SN)作为一种新兴的自杀手段,尤其是年轻人。鉴于传统公共卫生监测来源关于该主题的信息有限,我们研究了一个网上自杀论坛的帖子,\"被制裁的自杀,“这是有关SN使用和采购的主要信息来源。
    本研究旨在确定SN购买和使用的趋势,通过数据挖掘从论坛上的订阅者帖子获得。我们还旨在确定与SN共同出现的物质和主题,以及SN的用户和来源的地理分布。
    我们收集了该网站于2018年3月成立至2022年10月的所有公开可用信息。使用数据驱动方法,包括自然语言处理和机器学习,我们分析了SN提及随着时间的推移,包括SN消费者的位置和采购SN的来源。我们开发了基于变压器的源和位置分类器,以确定SN源的地理分布。
    与SN有关的帖子显示受欢迎程度上升,与疾病控制和预防中心(CDC)广泛的流行病学研究在线数据(=0.727;P<.001)和国家毒物数据系统(=0.866;P=.001)的数据相比,SN的实际使用与自杀意图之间存在统计学上的显着相关性。我们观察到止吐药的频繁出现,苯二氮卓类药物,和具有SN的酸调节剂。我们提出的基于机器学习的源和位置分类器可以检测到潜在的SN源,准确率为72.92%,并显示在美国和其他地方的消费。
    可以从在线论坛获得有关SN和其他新兴自杀机制的重要信息。
    UNASSIGNED: There is growing concern around the use of sodium nitrite (SN) as an emerging means of suicide, particularly among younger people. Given the limited information on the topic from traditional public health surveillance sources, we studied posts made to an online suicide discussion forum, \"Sanctioned Suicide,\" which is a primary source of information on the use and procurement of SN.
    UNASSIGNED: This study aims to determine the trends in SN purchase and use, as obtained via data mining from subscriber posts on the forum. We also aim to determine the substances and topics commonly co-occurring with SN, as well as the geographical distribution of users and sources of SN.
    UNASSIGNED: We collected all publicly available from the site\'s inception in March 2018 to October 2022. Using data-driven methods, including natural language processing and machine learning, we analyzed the trends in SN mentions over time, including the locations of SN consumers and the sources from which SN is procured. We developed a transformer-based source and location classifier to determine the geographical distribution of the sources of SN.
    UNASSIGNED: Posts pertaining to SN show a rise in popularity, and there were statistically significant correlations between real-life use of SN and suicidal intent when compared to data from the Centers for Disease Control and Prevention (CDC) Wide-Ranging Online Data for Epidemiologic Research (⍴=0.727; P<.001) and the National Poison Data System (⍴=0.866; P=.001). We observed frequent co-mentions of antiemetics, benzodiazepines, and acid regulators with SN. Our proposed machine learning-based source and location classifier can detect potential sources of SN with an accuracy of 72.92% and showed consumption in the United States and elsewhere.
    UNASSIGNED: Vital information about SN and other emerging mechanisms of suicide can be obtained from online forums.

    这项研究旨在评估抑郁症和精神分裂症患者的氧化应激参数,考虑到性别差异,表现出自杀行为,包含思想而没有实现的倾向,具有实现趋势的思想,和自杀企图。
    从精神科患者中选择120名符合纳入标准且不符合本研究排除标准的个体。在项目的初始阶段,符合研究条件的患者接受了M.I.N.I7.0.2问卷(迷你国际神经精神病学访谈).随后,在研究的第二阶段,为了进行生化评估,从患者身上采集静脉血样本,关注氧化应激参数。
    获得的结果表明,氧化还原生物标志物,即TOS(总氧化态)和OSI(TOS/TAC比),在女性的血浆中,随着自杀行为的严重程度而增加。SOD(Cu-Zn-超氧化物歧化酶)无明显变化,GPx(谷胱甘肽过氧化物酶),和GSH(还原型谷胱甘肽)浓度和活性在表现出自杀行为的组之间被记录。与对照组相比,观察到的抗氧化剂参数的浓度和活性变化仅是显着的。
    氧化还原生物标志物TOS和OSI在诊断真正有自杀风险的女性方面可能被证明是有价值的。另一方面,抗氧化参数-SOD,GPx,GSH可能有助于识别有自杀行为的患者,没有说明他们的强度。
    UNASSIGNED: This study aimed to evaluate oxidative stress parameters in individuals with depression and schizophrenia, considering gender differences, and manifesting suicidal behavior, encompassing thoughts without a tendency to be realized, thoughts with a tendency to be realized, and suicide attempts.
    UNASSIGNED: From among the patients from Department of Psychiatry 120 individuals were selected who met the inclusion criteria and did not meet the exclusion criteria for the study. In the initial phase of the project, patients eligible for the study underwent the M.I.N.I 7.0.2 questionnaire (Mini International Neuropsychiatric Interview). Subsequently, in the second phase of the research, venous blood samples were collected from the patients for the purpose of conducting biochemical assessments, focusing on oxidative stress parameters.
    UNASSIGNED: The obtained results suggest that redox biomarkers, namely TOS (total oxidation state) and OSI (TOS/TAC ratio), in the blood plasma of women increase in tandem with the severity of suicidal behavior. No notable alterations in SOD (Cu-Zn-superoxide dismutase), GPx (glutathione peroxidase), and GSH (reduced glutathione) concentrations and activity were noted between groups exhibiting suicidal behavior. The observed variations in the concentrations and activity of antioxidant parameters were significant solely in comparison to the control group.
    UNASSIGNED: Redox biomarkers TOS and OSI could prove valuable in diagnosing women at a genuine risk of committing suicide. On the other hand, antioxidant parameters - SOD, GPx, and GSH may be instrumental in identifying patients with suicidal behaviors, without specifying their intensity.
