Mental-disorders (MDs) are associated with premature mortality. Previous studies had limitations including confounding by physical-morbidities and lack of cause-specific mortality evaluation. We aimed to quantify mortality risk and life-expectancy gap across MDs in an Asian population. This retrospective population-based study investigated people with MDs (ascertained by ICD10-codes) in 2006–2021, utilizing comprehensive health-record-database of public-healthcare services in Hong-Kong. Individuals without MDs attending primary-care-clinics during study period served as comparisons. We estimated relative all-cause and cause-specific mortality risk using Cox-proportional hazards-regression models, and calculated excess life-years-lost (LYLs). Effect modification (sex, age, Charlson-comorbidity-index, socioeconomic-status (SES)) on relative risks was evaluated with subgroup-analyses. This analysis included 332,298 people with and 902,927 people without MDs. Any MD was associated with increased all-cause mortality (hazard-ratio (HR): 2.04 [95%Confidence-interval (CI)=2.02–2.07]) and excess LYLs (13.81 years [95%CI=13.60–13.98]). Eating-disorders exhibited the highest all-cause mortality (HR=9.43 [95%CI=6.83–13.02]), followed by developmental-disorders (HR=5.55 [95%CI=4.45–6.92]), personality-disorders (HR=4.50 [95%CI=4.06–4.98]) and substance-use disorders (HR=3.83 [95%CI=3.70–3.96]), with pronounced excess LYLs (14.18–17.41 years). Psychiatric-multimorbidity further increased excess mortality. Suicide was associated with the highest mortality risk (HR=8.69 [95%CI=7.97–9.45]). Natural causes accounted for most deaths (85%; HR range=1.50–2.76), while external causes explained 5% of all deaths (suicide: HR=8.69 [95%CI=7.97–9.45]). Men, younger age and lower SES were associated with increased all-cause and natural-cause mortality, while women and higher SES were linked to elevated external-cause mortality. This study highlighted transdiagnostic nature of premature mortality associated with MDs. Implementation of comprehensive multilevel interventions is warranted to narrow this mortality gap.
精神障碍(MDs)与过早死亡有关。以前的研究有局限性,包括身体发病率的混淆和缺乏病因特异性死亡率评估。我们的目的是量化亚洲人群中医学博士的死亡风险和预期寿命差距。这项基于人群的回顾性研究利用香港公共医疗服务的综合健康记录数据库,调查了2006-2021年md患者(由icd10 -code确定)。没有医学博士的个体在研究期间到初级保健诊所就诊作为比较。我们使用cox比例风险回归模型估计了相对全因和特定原因的死亡率风险,并计算了超额生命年损失(LYLs)。采用亚组分析评估影响因素(性别、年龄、charlson -comorbidi -index、社会经济状况(SES))对相对风险的影响。该分析包括332,298名MDs患者和902,927名非MDs患者。任何MD都与全因死亡率增加(危险比(HR): 2.04[95%可信区间(CI)=2.02-2.07])和超额lyl(13.81年[95%CI=13.60-13.98])相关。进食障碍的全因死亡率最高(HR=9.43 [95%CI=6.83-13.02]),其次是发育障碍(HR=5.55 [95%CI=4.45-6.92])、人格障碍(HR=4.50 [95%CI=4.06-4.98])和物质使用障碍(HR=3.83 [95%CI=3.70-3.96]), LYLs明显偏高(14.18-17.41年)。精神疾病多病进一步增加了超额死亡率。自杀与最高的死亡风险相关(HR=8.69 [95%CI=7.97-9.45])。自然原因占大多数死亡(85%;HR范围=1.50-2.76),而外部原因占所有死亡的5%(自杀:HR=8.69 [95%CI=7.97-9.45])。男性,年龄小,社会经济地位低与全因和自然原因死亡率增加有关,而女性,社会经济地位高与外因死亡率增加有关。这项研究强调了与MDs相关的过早死亡的跨诊断性质。有必要实施全面的多层次干预措施,以缩小这一死亡率差距。

This study aimed to evaluate the real-world effectiveness and psychiatric safety of tirzepatide among adults with schizophrenia spectrum disorders, focusing on the risks of mortality, hospitalization, and suicidal behavior. Based on the electronic health records from the TriNetX Global Collaborative Network, adults with schizophrenia spectrum disorders who initiated tirzepatide on or before June 1, 2024, were included. Tirzepatide users were propensity score–matched 1:1 to nonusers based on demographic and clinical variables. The primary outcome was a composite of all-cause mortality, hospitalization, and suicidal behavior evaluated between 30 and 365 days after the index date. Secondary outcomes included each component separately. Cox proportional hazards models and Kaplan–Meier estimators were used to estimate associations. Subgroup and sensitivity analyses were performed. Overall, a total of 1809 matched pairs were included. Tirzepatide use was associated with lower risk of the composite outcome (hazard ratio [HR], 0.66; 95 % confidence interval [CI], 0.55–0.79), as well as all-cause mortality (HR, 0.18; 95 % CI, 0.06–0.51), hospitalization (HR, 0.75; 95 % CI, 0.61–0.92), and suicidal behavior (HR, 0.43; 95 % CI, 0.27–0.70). Risk reduction was generally consistent across subgroups. Control outcome analyses supported internal validity. In conclusion, tirzepatide use in patients with schizophrenia spectrum disorders is associated with improved clinical outcomes, including reduced risks of mortality, hospitalization, and suicidal behavior. These findings support the integration of tirzepatide into metabolic management strategies for this high-risk population, offering benefits for glycemic control and potentially for psychiatric outcomes.
本研究旨在评估替西帕肽在精神分裂症谱系障碍成人患者中的实际有效性和精神病学安全性,重点关注其死亡率、住院率和自杀行为的风险。根据TriNetX全球协作网络的电子健康记录,纳入了在2024年6月1日或之前开始使用替西帕肽的精神分裂症谱系障碍成年人。根据人口统计学和临床变量,替西肽使用者与非使用者的倾向评分匹配为1:1。主要结局是指标日期后30至365天内评估的全因死亡率、住院率和自杀行为的综合结果。次要结局分别包括每个成分。使用Cox比例风险模型和Kaplan-Meier估计器来估计相关性。进行亚组分析和敏感性分析。总共纳入了1809对匹配的配对。使用替西帕肽与综合结局(危险比[HR], 0.66; 95%可信区间[CI], 0.55-0.79)、全因死亡率(危险比,0.18;95% CI, 0.06-0.51)、住院(危险比,0.75;95% CI, 0.61-0.92)和自杀行为(危险比,0.43;95% CI, 0.27-0.70)的风险较低相关。风险降低在各个亚组中总体上是一致的。对照结果分析支持内部效度。总之,在精神分裂症谱系障碍患者中使用替西帕肽可改善临床结果,包括降低死亡、住院和自杀行为的风险。这些发现支持将替西帕肽整合到这一高危人群的代谢管理策略中,为血糖控制和潜在的精神预后提供益处。

Different effect of adverse childhood experiences on white matter microstructure in major depression and bipolar disorder: moderating role of genetic liability 童年不良经历对重度抑郁症和双相情感障碍白质微观结构的不同影响:遗传倾向的调节作用

Adverse childhood experiences (ACEs) are risk factors for both major depressive (MDD) and bipolar disorder. ACEs have been associated with white matter (WM) alterations, but whether they have different effects in MDD and BD remains unclear. Polygenic risk scores (PRS) allow for an individual estimation of genetic liabilities for most psychiatric conditions. The aim of the present study was to characterize the effect of ACEs on WM microstructure in MDD and BD, testing a possible differential effect between the two diagnoses and investigating whether genetic liabilities might modulate this relation. 260 depressed inpatients (140 MDD and 120 BD, mean age 49.29 ± 10.60, F = 161) underwent 3T MRI scan and ACEs evaluation. MDD and BD PRS were calculated in a subset of patients. Significant ACEs x diagnosis interactions were found for several DTI metrics. Single group analyses showed widespread detrimental effects of ACEs on WM integrity in BD, and less pronounced effects in MDD. Significant moderating effect of BD PRS in the whole sample and in MDD specifically were found for the relation between ACEs, fractional anisotropy and radial diffusivity, with bipolar-like relations for higher values of BD PRS. The differential effect of ACEs on WM microstructure in the two diagnostic groups points towards putative differential pathophysiological routes through which childhood maltreatment affects the two conditions, while the identification of a BD PRS moderation on the whole sample and in MDD specifically sheds light on the causal relation between ACEs, diagnostic phenotype and DTI metrics, and provides a possible tool to disentangle MDD heterogeneity.
不良童年经历(ace)是重度抑郁症(MDD)和双相情感障碍的危险因素。ace与白质(WM)改变有关,但它们对重度抑郁症和双相障碍是否有不同的影响尚不清楚。多基因风险评分(PRS)允许对大多数精神疾病的遗传责任进行个体估计。本研究的目的是表征ace对MDD和BD中WM微观结构的影响,测试两种诊断之间可能的差异效应,并研究遗传负荷是否可能调节这种关系。260例住院抑郁症患者(重度抑郁症140例,双相抑郁症120例,平均年龄49.29±10.60岁,F = 161)行3T MRI扫描和ace评估。计算一部分患者的MDD和BD PRS。在几个DTI指标中发现了显著的ace与诊断的相互作用。单组分析显示,ace对BD患者的WM完整性有广泛的有害影响,而对MDD患者的影响不太明显。在整个样本中,特别是在MDD中,BD PRS对ace、分数各向异性和径向扩散率之间的关系有显著的调节作用,在更高的BD PRS值时呈双极样关系。在两个诊断组中,ace对WM微观结构的不同影响指向了儿童虐待影响这两种情况的可能的不同病理生理途径,而在整个样本和MDD中发现的BD PRS调节作用特别揭示了ace、诊断表型和DTI指标之间的因果关系,并提供了一种可能的工具来解决MDD的异质性。

The high prevalence, persistence and clinical burden of cognitive impairment on health outcomes in persons with schizophrenia and bipolar disorder invites the need for innovative, mechanistically informed pharmacotherapeutic interventions. Evidence implicates dysregulation of muscarinic signalling as a mediator of cognitive dysfunction, identifying it as a potential therapeutic target. In accordance with the PRISMA guidelines, a systematic search was performed using the following electronic databases: PubMed, Medline, Cochrane Library, PsycInfo, Embase, Scopus, and Web of Science. Databases were searched from inception to May 1, 2025. Study screening and selection was performed by three reviewers (K.V., B.S., and B.W.). Included studies reported on the effects of xanomeline and/or xanomeline trospium on cognitive function. A total of 24 studies were included in this review. Preclinical and clinical studies consistently demonstrate that xanomeline trospium is well tolerated in both short and long-term evaluations. Furthermore, xanomeline trospium has been associated with cognitive improvements in both animal models and clinical populations (e.g., Alzheimer’s disease (AD), schizophrenia), including improvements in verbal learning, delayed memory, and reaction time. Xanomeline trospium, an FDA approved muscarinic M1/M4 partial agonist with demonstrated safety, tolerability, and efficacy, represents a novel pharmacological intervention for the treatment of schizophrenia. The convergence of preclinical and clinical findings supports the hypothesis that xanomeline trospium exerts direct pro cognitive effects in persons with schizophrenia, bipolar disorder, and potentially other neuropsychiatric conditions (e.g., AD). Limitations of the current study include limited indications investigated and the absence of a comprehensive analysis of xanomeline’s overall neurobiologic effects.
精神分裂症和双相情感障碍患者中认知障碍的高流行率、持续性和临床负担对健康结果的影响促使人们需要创新的、机械知情的药物治疗干预措施。证据暗示毒蕈碱信号失调是认知功能障碍的中介,将其确定为潜在的治疗靶点。根据PRISMA指南,使用以下电子数据库进行系统检索:PubMed、Medline、Cochrane Library、PsycInfo、Embase、Scopus和Web of Science。数据库从开始到2025年5月1日进行了搜索。研究筛选和选择由三位审稿人(k.v.、b.s.和B.W.)进行。纳入的研究报告了xanomeline和/或xanomeline trospium对认知功能的影响。本综述共纳入24项研究。临床前和临床研究一致表明,xanomeline trospium在短期和长期评估中都具有良好的耐受性。此外,xanomeline trospium与动物模型和临床人群(例如阿尔茨海默病(AD)、精神分裂症)的认知改善有关,包括改善言语学习、延迟记忆和反应时间。Xanomeline trospium是FDA批准的毒蕈碱M1/M4部分激动剂,具有安全性、耐受性和有效性,代表了一种治疗精神分裂症的新型药物干预。临床前和临床研究结果的融合支持了xanomeline trospium对精神分裂症、双相情感障碍和潜在的其他神经精神疾病(如AD)患者有直接的认知促进作用的假设。目前研究的局限性包括调查的适应症有限和缺乏对xanomeline整体神经生物学效应的全面分析。

Oxidative stress is implicated in schizophrenia. Glutathione (GSH), a crucial endogenous antioxidant, is usually reduced in individuals with schizophrenia. GSH and its precursor, N-acetyl cysteine, have demonstrated potential as adjunctive treatment for schizophrenia; however, their effectiveness appears inconsistent, possibly because of their limited ability to penetrate the blood-brain barrier (BBB). Administration of sodium benzoate, capable of crossing BBB, enhanced GSH capacity and antipsychotic-like activity in animals. Further, adjunctive benzoate therapy improved clinical and functional outcomes in patients with schizophrenia, including clozapine-resistant schizophrenia (CRS). Whether sodium benzoate can also boost GSH to exert its therapeutic efficacy for schizophrenia deserves elucidation. This secondary analysis used data from a double-blind trial, in which 60 patients with CRS were randomized to receive addon treatment of sodium benzoate (n = 40) or placebo (n = 20) for 6 weeks. Clinical and functional assessments were conducted bi-weekly. Plasma levels of GSH were assayed at baseline and endpoint. As a result, six-week treatment of sodium benzoate was linked to increased GSH levels than placebo. Among the 40 benzoate receivers, the changes in GSH levels were correlated with the improvements in positive symptoms, negative symptoms, quality of life, and global function. In comparison, among placebo recipients, GSH changes were not associated with any changes in clinical or functional variables. The findings suggest that benzoate treatment may be related with elevation in GSH levels in CRS patients and improvement in functional outcomes as well as positive and negative symptoms. Longer-term studies in other populations are necessary in the future.
氧化应激与精神分裂症有关。谷胱甘肽(GSH)是一种重要的内源性抗氧化剂,在精神分裂症患者中通常会减少。谷胱甘肽及其前体n -乙酰半胱氨酸已被证明具有作为精神分裂症辅助治疗的潜力;然而,它们的效果似乎不一致,可能是因为它们穿透血脑屏障(BBB)的能力有限。能穿过血脑屏障的苯甲酸钠在动物体内增强谷胱甘肽能力和抗精神病样活性。此外,辅助苯甲酸酯治疗改善了精神分裂症患者的临床和功能结局,包括氯氮平抵抗性精神分裂症(CRS)。苯甲酸钠是否也能促进谷胱甘肽的分泌,从而发挥其治疗精神分裂症的作用,值得进一步研究。这项二次分析使用了一项双盲试验的数据,在该试验中,60名CRS患者随机接受6周的苯甲酸钠(n = 40)或安慰剂(n = 20)的附加治疗。临床和功能评估每两周进行一次。在基线和终点检测血浆谷胱甘肽水平。结果,六周的苯甲酸钠治疗与安慰剂相比,GSH水平升高有关。在40名苯甲酯受体中,GSH水平的变化与阳性症状、阴性症状、生活质量和整体功能的改善相关。相比之下,在安慰剂接受者中,谷胱甘肽的变化与临床或功能变量的任何变化无关。研究结果表明,苯甲酯治疗可能与CRS患者谷胱甘肽水平升高、功能结局以及阳性和阴性症状的改善有关。未来有必要对其他人群进行长期研究。

Rodent studies have shown that psychedelic drugs can enhance fear extinction. However, investigations to date have relied on normative aversive conditioning procedures, which limit their relevance to trauma-related memories, as these tend to be overgeneralized and resistant to extinction. Fear extinction depends on activity and plasticity within the infralimbic (IL) region of the medial prefrontal cortex and is regulated by brain-derived neurotrophic factor (BDNF). Ayahuasca (AYA), a brew containing the serotonergic psychedelic N,N-dimethyltryptamine (DMT), facilitates fear extinction in rodents and increases BDNF levels/signaling. Here, we investigated whether AYA attenuates extinction deficits and generalized fear induced by preconditioning restraint stress or high-intensity contextual fear conditioning, and whether these effects depend on BDNF-TrkB receptor signaling in the IL cortex. Adult male and female rats underwent the protocols above and received oral AYA one hour before each of the two extinction sessions conducted on consecutive days. Repeated administration of AYA containing 0.3 mg/kg of DMT enhanced extinction learning and its retention, effects that were abolished by bilateral intra-IL cortex infusion of an anti-BDNF antibody or the TrkB receptor antagonist ANA-12. AYA treatment also reduced fear generalization, an action that was BDNF-dependent in the IL cortex of females but not males. Overall, these findings indicate that AYA can modulate maladaptive fear memories through cortical mechanisms involving BDNF signaling, highlighting the potential of psychedelics as enhancers for extinguishing difficult-to-treat memories like those underlying post-traumatic stress disorder.
对啮齿动物的研究表明,迷幻药可以增强恐惧消退。然而,迄今为止的研究都依赖于规范的厌恶条件反射程序,这限制了它们与创伤相关记忆的相关性,因为这些记忆往往是过度概括的,难以消除。恐惧消退取决于内侧前额叶皮层边缘下(IL)区域的活动和可塑性,并受脑源性神经营养因子(BDNF)的调节。死藤水(AYA)是一种含有5 -羟色胺能致幻剂N,N-二甲基色胺(DMT)的饮料,能促进啮齿动物的恐惧消除,并增加BDNF水平/信号传导。在这里,我们研究了AYA是否减弱了由预处理约束应激或高强度情境恐惧条件反射引起的灭绝缺陷和广义恐惧,以及这些作用是否依赖于IL皮质中的BDNF-TrkB受体信号。成年雄性和雌性大鼠接受上述方案,并在连续进行的两次灭绝活动前一小时口服AYA。反复给药含有0.3 mg/kg DMT的AYA可增强消退学习及其保留,双侧il皮质内输注抗bdnf抗体或TrkB受体拮抗剂ANA-12可消除这种作用。AYA治疗还减少了恐惧泛化,这是一种依赖于bdnf的行为,在女性的IL皮质中,而不是男性。总的来说,这些发现表明AYA可以通过涉及BDNF信号传导的皮质机制调节不适应的恐惧记忆,突出了迷幻药作为消除难以治疗的记忆的增强剂的潜力,比如那些潜在的创伤后应激障碍。

Abnormal functional connectivity (FC) has been consistently associated with bipolar disorders (BD). Classical FC analyses assume stationarity of brain interactions, although connectivity actually varies over time. Here, we examined alterations in dynamic functional network connectivity (dFNC) in BD, their associations with symptom severity and global functioning, and potential differences between bipolar disorder type I (BD1) and type II (BD2).
In this case-control study, we investigated dFNC in 57 patients with BD (29 BD1, 28 BD2) and 43 healthy controls (HCs). Most patients were euthymic at scanning (∼86 %), with only a minority showing residual depressive or hypomanic/mixed symptoms. Resting-state fMRI data were decomposed with spatially constrained independent component analysis and analyzed using a sliding-window approach. Meta-state metrics—number of meta-states, transitions, total distance, and span—were derived and compared across groups. Correlations with clinical measures and Global Assessment of Functioning (GAF) scores were tested. Dynamic metrics (number of meta-states, state transitions, and total distance) were reduced in BD relative to HCs, with the greatest reduction in BD1, followed by BD2. State span did not differ between groups. Across the BD sample, higher GAF scores were positively associated with greater dynamic fluidity, whereas no significant associations emerged with standard symptom scales.
In conclusion, BD is characterized by a graded disruption of the spatio-temporal dynamics of large-scale brain networks, most pronounced in BD1. Reduced neural flexibility is linked to poorer global functioning, suggesting that dFNC meta-state metrics may provide clinically relevant markers of illness burden in bipolar disorder.
功能连接异常(FC)一直与双相情感障碍(BD)相关。经典的FC分析假设大脑相互作用是平稳的,尽管连通性实际上随着时间的推移而变化。在这里,我们研究了双相情感障碍中动态功能网络连接(dFNC)的改变,它们与症状严重程度和整体功能的关系,以及I型双相情感障碍(BD1)和II型双相情感障碍(BD2)之间的潜在差异。在这项病例对照研究中,我们调查了57例BD患者(29例BD1, 28例BD2)和43例健康对照(hc)的dFNC。大多数患者在扫描时心境良好(约86%),只有少数患者表现出残留的抑郁或轻躁/混合症状。静息状态fMRI数据采用空间约束独立分量分析进行分解,并采用滑动窗口方法进行分析。元状态度量——元状态的数量、转换、总距离和跨度——被导出并跨组进行比较。测试了与临床测量和总体功能评估(GAF)评分的相关性。动态指标(元状态数量、状态转换和总距离)在BD中相对于hcc减少,其中BD1减少最多,其次是BD2。各组之间的状态跨度没有差异。在BD样本中,较高的GAF分数与较高的动态流动性呈正相关,而与标准症状量表没有显著关联。总之,BD的特征是大尺度脑网络时空动态的逐步中断,在BD1中最为明显。神经灵活性降低与整体功能较差有关,表明dFNC元状态指标可能提供双相情感障碍疾病负担的临床相关标记。

Evidence has underscored clinical significance of subjective quality of life (SQoL) as a key therapeutic goal for early psychosis. However, the patterns, predictors and outcomes of SQoL trajectories over long-term follow-up in early psychosis have not been explored. We conducted a 12-year follow-up of the randomized-controlled-trial on extended early intervention for first-episode psychosis with an aim to identify distinct trajectories of the SQoL, their baseline predictors and relationships with 12-year outcomes. Premorbid adjustment, illness characteristics, symptom severity, functioning, and treatment profiles were assessed. Latent growth mixture modeling was employed to derive SQoL trajectories based on 36-Item Short Form Health Survey (SF-36) mental-health component summary scores over 12-year follow-up. Participants who completed SF-36 at three or more time points, including baseline, and 1-, 2-, 3- and 12-year follow-up, were included in the analysis, resulting in 144 patients. Our results identified three distinct trajectories, including high-stable class (36.8 %, n = 53), moderate-improving class (40.3 %, n = 58) and low-stable class (22.9 %, n = 33). Patients in high-stable class had less severe depressive symptoms at baseline than those in moderate-improving class, and less severe positive, negative and depressive symptoms at baseline compared to patients in low-stable class. Additionally, patients with high-stable trajectory exhibited higher rate of personal recovery and lower depressive symptom severity at 12-year follow-up relative to patients with low-stable trajectory. In conclusion, approximately one-fourths of patients displayed consistently poor SQoL over 12 years. Depressive symptoms represent a major determinant of SQoL trajectories, indicating the need to optimize treatment for depression in early psychosis to enhance SQoL outcome.
证据强调了主观生活质量(SQoL)作为早期精神病的关键治疗目标的临床意义。然而,长期随访的早期精神病患者sql轨迹的模式、预测因素和结果尚未得到探讨。我们进行了一项为期12年的随机对照试验,对首发精神病的延长早期干预进行了随访,目的是确定SQoL的不同轨迹、基线预测因子及其与12年预后的关系。评估了病前调整、疾病特征、症状严重程度、功能和治疗概况。在随访12年的36项简短健康调查(SF-36)心理健康成分总结得分基础上,采用潜在生长混合模型推导sql轨迹。在三个或更多时间点完成SF-36的参与者,包括基线,1年,2年,3年和12年的随访,被纳入分析,共有144例患者。我们的研究结果确定了三种不同的轨迹,包括高稳定型(36.8%,n = 53)、中度改善型(40.3%,n = 58)和低稳定型(22.9%,n = 33)。高稳定级患者在基线时抑郁症状的严重程度低于中度改善级患者,在基线时阳性、阴性和抑郁症状的严重程度低于低稳定级患者。此外,在12年的随访中,高稳定轨迹的患者表现出较高的个人恢复率和较低的抑郁症状严重程度。总之,大约四分之一的患者在12年的时间里一直表现出较差的生存质量。抑郁症状是SQoL轨迹的主要决定因素,表明需要优化早期精神病抑郁症的治疗,以提高SQoL结果。
