In addition to understanding empathy in an affective and cognitive dimension, the physiological domain plays a crucial role, especially in the emotional dynamics of interpersonal interactions during psychotherapy. Within the complex bio-psycho-social system of cognitive behavioural therapy language, cognition, emotion and physiological states of both, client and therapist, intertwine through interaction dynamics. The current study aimed to explore interpersonal physiological dynamics during psychotherapy sessions as an objective biomarker for predicting therapy outcome. In a follow-up assessment design, involving 25 client-psychotherapist dyads, wearable sensors monitored individual’s heart rate, while video cameras recorded movement behaviour during regular cognitive behavioural therapy sessions. Post-session reports and symptom questionnaires were collected from both, clients and therapists, after each session. Results showed that synchrony in head movement and heart rate emerged during psychotherapy sessions. Notably, heart rate synchrony from the initial session predicted changes in patients’ self-rated global severity index over time. The objective predictor, heart rate synchrony, emerged as particularly robust, surpassing patients’ subjective ratings of affiliation in explaining a higher variance of the therapy outcome variable. These findings highlight the potential shown by remote biomarker sensing of interpersonal dynamics for the prediction of psychotherapeutic effectiveness.
除了从情感和认知维度理解移情之外,生理领域也发挥着至关重要的作用,尤其是在心理治疗过程中人际互动的情感动力方面。在认知行为疗法这个复杂的生物-心理-社会系统中,求助者和治疗师的语言、认知、情感和生理状态通过互动动态交织在一起。本研究旨在探索心理治疗过程中的人际生理动态,以此作为预测治疗结果的客观生物标志物。在一项涉及 25 个客户-心理治疗师二人组的后续评估设计中,可穿戴传感器监测了个人的心率,而摄像机则记录了定期认知行为治疗过程中的动作行为。每次疗程结束后,都会向客户和治疗师收集疗程后报告和症状问卷。结果显示,在心理治疗过程中,头部运动和心率出现了同步。值得注意的是,初次治疗时的心率同步可以预测患者自评的总体严重程度指数随时间推移而发生的变化。心率同步性这一客观预测因子尤其强大,在解释治疗结果变量的更大方差方面超过了患者对从属关系的主观评价。这些发现凸显了人际动态远程生物标记感应在预测心理治疗效果方面的潜力。

Background Depression is one of the most common mental illnesses worldwide and is a major burden for those affected. As conventional therapies do not always work and are also associated with side effects, alternative treatment methods are urgently indicated. In the past, exercise has established itself as a seemingly good alternative treatment method. The aim of this work is to provide a state of the art review and to check whether there are new findings since the publication of the article by Wegner et al. [1].
背景 抑郁症是全球最常见的精神疾病之一,也是患者的主要负担。由于传统疗法并不总是有效,而且还伴有副作用,因此迫切需要替代治疗方法。过去,运动已成为一种看似不错的替代治疗方法。这项工作的目的是提供一份最新的综述,并检查自 Wegner 等人的文章[1]发表以来是否有新的发现。

Large-scale genome-wide association studies of schizophrenia have uncovered hundreds of associated loci but with extremely limited representation of African diaspora populations. We surveyed electronic health records of 200,000 individuals of African ancestry in the Million Veteran and All of Us Research Programs, and, coupled with genotype-level data from four case-control studies, realized a combined sample size of 13,012 affected and 54,266 unaffected persons. Three genome-wide significant signals - near PLXNA4, PMAIP1, and TRPA1 - are the first to be independently identified in populations of predominantly African ancestry. Joint analyses of African, European, and East Asian ancestries across 86,981 cases and 303,771 controls, yielded 376 distinct autosomal loci, which were refined to 708 putatively causal variants via multi-ancestry fine-mapping. Utilizing single-cell functional genomic data from human brain tissue and two complementary approaches, transcriptome-wide association studies and enhancer-promoter contact mapping, we identified a consensus set of 94 genes across ancestries and pinpointed the specific cell types in which they act. We identified reproducible associations of schizophrenia polygenic risk scores with schizophrenia diagnoses and a range of other mental and physical health problems. Our study addresses a longstanding gap in the generalizability of research findings for schizophrenia across ancestral populations, underlining shared biological underpinnings of schizophrenia across global populations in the presence of broadly divergent risk allele frequencies.
大规模的精神分裂症全基因组关联研究发现了数百个相关基因位点,但非洲散居人群的代表性极为有限。我们调查了 "百万退伍军人 "和 "我们所有人 "研究计划中 20 万非洲裔个体的电子健康记录,再加上四项病例对照研究的基因型数据,得到了 13012 名受影响者和 54266 名未受影响者的综合样本量。PLXNA4 、PMAIP1 和 TRPA1 附近的三个全基因组重要信号是首次在以非洲血统为主的人群中独立发现的。通过对非洲、欧洲和东亚血统的 86,981 例病例和 303,771 例对照进行联合分析,发现了 376 个不同的常染色体位点,并通过多种系精细图谱将这些位点细化为 708 个可能的致病变异。利用来自人类脑组织的单细胞功能基因组数据和两种互补方法(全转录组关联研究和增强子-启动子接触图谱),我们确定了一套跨血统的 94 个基因共识集,并精确定位了这些基因作用的特定细胞类型。我们确定了精神分裂症多基因风险评分与精神分裂症诊断及其他一系列身心健康问题之间的可重复性关联。我们的研究填补了精神分裂症研究成果在不同祖先人群中普遍适用性方面的一个长期空白,强调了在风险等位基因频率大相径庭的情况下,全球人群中精神分裂症的共同生物学基础。

BackgroundEye tracking (ET) is emerging as a promising early and objective screening method for autism spectrum disorders (ASD), but it requires more reliable metrics with enhanced sensitivity and specificity for clinical use. MethodsThis study introduces a suite of novel ET metrics: Area of Interest (AOI) Switch Counts (ASC), Favorable AOI Shifts (FAS) along self-determined pathways, and AOI Vacancy Counts (AVC). These metrics were applied to toddlers and preschoolers diagnosed with ASD. The correlation between these new ET metrics and Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) scores was assessed using linear regression. Sensitivity and specificity of the cut-off scores were also evaluated to predict diagnosis. ResultsOur findings indicate significantly lower FAS and ASC and higher AVC (P < 0.05) in children with ASD compared to their non-ASD counterparts within this high-risk cohort. There were no significant differences in total fixation time or pupil size (p > 0.05). Additionally, FAS was negatively correlated with ADOS-2 total scores and the social affect (SA) subscale (p < 0.05). Among these new ET metrics, AVC yielded the best sensitivity (88-100%) and specificity (80-88%) with a cut-off score of 0.305-0.306, followed by FAS and ASC for distinguishing ASD from non-ASD for diagnosis. ConclusionsThis study confirms the utility of innovative ET metrics FAS, AVC, and ASC, which exhibit markedly improved sensitivity and specificity, enhancing ASD screening and diagnostic processes.
背景眼动追踪(ET)正在成为自闭症谱系障碍(ASD)的一种有前途的早期客观筛查方法,但它需要更可靠、灵敏度和特异性更高的指标才能用于临床。方法本研究介绍了一套新型 ET 指标:兴趣区(AOI)转换计数(ASC)、沿自决路径的有利兴趣区转换(FAS)和兴趣区空缺计数(AVC)。这些指标适用于被诊断为 ASD 的幼儿和学龄前儿童。通过线性回归评估了这些新的 ET 指标与自闭症诊断观察表第二版(ADOS-2)评分之间的相关性。此外,还评估了预测诊断的临界分数的敏感性和特异性。结果我们的研究结果表明,在这个高危人群中,与非 ASD 儿童相比,ASD 儿童的 FAS 和 ASC 明显较低,而 AVC 则较高(P < 0.05)。总固定时间和瞳孔大小没有明显差异(P 0.05)。此外,FAS 与 ADOS-2 总分和社会情感 (SA) 分量表呈负相关(p < 0.05)。在这些新的 ET 指标中,AVC 的灵敏度(88%-100%)和特异度(80%-88%)最好,临界值为 0.305-0.306,其次是 FAS 和 ASC,可用于区分 ASD 和非 ASD 的诊断。结论这项研究证实了创新性 ET 指标 FAS、AVC 和 ASC 的实用性,它们的灵敏度和特异性都有显著提高,从而加强了 ASD 筛查和诊断过程。

Abstract Problem Statement:During the COVID-19 pandemic, health care services were limited by the restrictive measures implemented. As an adaptation mechanism, telemedicine was introduced for ambulatory care at the Honorio Delgado Hideyo Noguchi National Institute of Mental Health (NIMH). This study aimed to estimate the survival function (SF) for loss to follow-up (LTFU) over two years before and after the onset of the COVID-19 pandemic, and its association with clinical and sociodemographic variables.Study Design:A single-cohort study was conducted, following a random sample of adult ambulatory patients at NIHM from April 15, 2018, to April 15, 2022. Patients were followed until LTFU, referral to another institution, death, or the end of study. The main analysis involved estimating the SF for LTFU for the overall follow up period, as well as separately for the periods pre and post implementation of telemedicine. Also, risk factors hypotheses were tested using Cox regression.Results:Data from 4887 visits of 356 patients were collected. A total of 118 (33.1%) presented LTFU, with SF of 53.9% during the overall four years of follow-up. After two years of follow-, those starting treatment at NIMH before the implementation of telemedicine had a higher SF (77.3 vs 63%). A higher hazard ratio (HR) for LTFU was found in the group that started care at NIMH after the implementation of telemedicine, compared to those who started previously (HR=2.53; 95% CI: 1.55-4.51). Additionally, receiving care in the anxiety disorders (HR=1.86; 95% CI: 1.03-3.33) and personality disorders programs (HR=1.81; 95% CI: 1.02-3.22) was associated with a higher risk of LTFU compared to the psychosis program. No significant difference was found in the risk of LTFU between telemedicine vs. face-to face attention. Conclusions:A significant association was found between LTFU and starting treatment at NIMH after the onset of the COVID-19 pandemic and implementation of telemedicine. However, no evidence supports that this might be due to the practice of telemedicine. A different clinical profile of patients that started treatment at NIMH following the government implementation of changes to the public health system might explain these findings and should be studied. Keywords: COVID-19, telemedicine, psychiatry, health services
问题陈述:在 COVID-19 大流行期间,医疗服务受到了限制性措施的限制。作为一种适应机制,Honorio Delgado Hideyo Noguchi国家精神卫生研究所(NIMH)在非住院治疗中引入了远程医疗。本研究旨在估算COVID-19大流行前后两年内失去随访(LTFU)的生存函数(SF),以及其与临床和社会人口学变量的关联。研究设计:本研究采用单队列研究方法,从2018年4月15日至2022年4月15日对国立精神卫生研究所的成年门诊患者进行随机抽样随访。患者随访至LTFU、转诊至其他机构、死亡或研究结束。主要分析包括估算整个随访期间的LTFU SF,以及实施远程医疗前后两个时期的LTFU SF。结果:共收集到 356 名患者 4887 次就诊的数据。在四年的随访中,共有 118 人(33.1%)出现失访,失访率为 53.9%。随访两年后,在远程医疗实施前开始在 NIMH 接受治疗的患者的 SF 值更高(77.3 vs 63%)。与之前开始接受治疗的患者相比,在远程医疗实施后开始在NIMH接受治疗的群体中,LTFU的危险比(HR)较高(HR=2.53;95% CI:1.55-4.51)。此外,与精神病项目相比,在焦虑症项目(HR=1.86;95% CI:1.03-3.33)和人格障碍项目(HR=1.81;95% CI:1.02-3.22)接受治疗与更高的LTFU风险相关。远程医疗与面对面治疗的LTFU风险没有明显差异。结论:在COVID-19大流行和远程医疗实施后,LTFU与开始在NIMH接受治疗之间存在明显关联。但是,没有证据表明这可能是远程医疗实践造成的。政府对公共卫生系统实施改革后,开始在NIMH接受治疗的患者的临床情况有所不同,这可能是这些发现的原因,应对此进行研究。关键词:COVID-19、远程医疗COVID-19、远程医疗、精神病学、医疗服务

Affect variability is determined by how often and how strongly negative affect changes over time. Cisgender women report greater variability in affect than cisgender men. It has been suggested that sex hormone changes may influence affect variability. Transgender people frequently opt to use sex hormones in the form of gender-affirming hormone therapy (GAHT), but the extent to which GAHT can change negative affect variability is not yet clear. Therefore, this study aims to study changes in negative affect variability after starting GAHT.We have included data from 94 participants from the RESTED study: 49 transmasculine (TM) participants (assigned female at birth, starting testosterone) and 45 transfeminine (TF) participants (assigned male at birth, starting estrogens and anti-androgens). Participants completed up to 7 consecutive daily diaries at each of three time points: before starting GAHT, and after 3 and 12 months of GAHT. The daily diaries collected participants' reports on symptoms related to negative affect: experienced low mood, less interest, tense feelings and restless feelings. We have used linear mixed models to compare negative affect variability during one week, corrected for mean negative affect, between gender groups (TM versus TF) and measurement time points.Results show that in the TM group, variability in low mood, tense feelings and restless feelings decreases after 12 months of GAHT. In the TF group, variability in low mood increases after 3 months and 12 months of GAHT, as does variability in restless feelings after 3 months of GAHT. Group comparisons indicate significant group differences in changes in variability in low mood and restless feelings, with stronger increases in variability of negative affect in the TF group compared to TM group after 3 and 12 months of GAHT. Our findings indicate that variability patterns in negative affect in transgender persons tend to cross-over from being consistent with sex assigned at birth before GAHT to being more in line with gender identity after 12 months of GAHT. Future studies should focus on measuring both negative and positive affect variability during GAHT, preferably through multiple measurements per day, taking into account diverse social and daily contextual factors during GAHT.
情感的可变性取决于负面情感随时间变化的频率和强度。与同性别的男性相比,同性别的女性报告的情感变异性更大。有人认为,性激素的变化可能会影响情感的可变性。变性人经常选择以性别确认激素疗法(GAHT)的形式使用性激素,但性别确认激素疗法能在多大程度上改变负面情绪的变异性尚不清楚。因此,本研究旨在研究开始接受 GAHT 治疗后负面情绪变异性的变化:我们纳入了 RESTED 研究中 94 名参与者的数据:49 名跨男性(TM)参与者(出生时被分配为女性,开始使用睾酮)和 45 名跨女性(TF)参与者(出生时被分配为男性,开始使用雌激素和抗雄激素)。参与者在三个时间点(开始 GAHT 前、GAHT 3 个月和 12 个月后)分别连续填写多达 7 篇每日日记。每日日记收集了参与者对负面情绪相关症状的报告:情绪低落、兴趣减退、紧张感和烦躁不安。我们使用线性混合模型比较了不同性别组(TM 组和 TF 组)和不同测量时间点一周内的负性情绪变异性,并对平均负性情绪进行了校正。结果显示,在 TM 组中,情绪低落、紧张感和不安感的变异性在 GAHT 12 个月后有所降低。在 TF 组中,情绪低落的变异性在 GAHT 3 个月和 12 个月后有所增加,不安情绪的变异性在 GAHT 3 个月后也有所增加。小组比较表明,在情绪低落和烦躁不安的变异性变化方面存在明显的小组差异,与 TM 组相比,TF 组的负面情绪变异性在 GAHT 3 个月和 12 个月后增加得更厉害。我们的研究结果表明,变性人负面情绪的变异模式往往会从 GAHT 前与出生时的性别一致转变为 GAHT 12 个月后与性别认同更加一致。未来的研究应重点测量变性人性别测试期间的消极和积极情绪变异,最好每天进行多次测量,并考虑到变性人性别测试期间的各种社会和日常环境因素。

Current approaches to optimize the efficacy of repetitive transcranial magnetic stimulation (rTMS) for depressive symptoms focus on personalizing targets and parameters. But what should occur during these three-to-forty-minute sessions remains under-investigated. Specific concerns include evidence suggesting brain state modulates the brain response to stimulation, and the potential to boost antidepressant efficacy by administering rTMS concurrently with psychological methods. Thus, conducted a scoping review and meta-analysis, per PRISMA-ScR guidelines, to pool studies that administered rTMS during psychological tasks or interventions. PubMed and Web of Science databases were searched from inception to 10 July 2024. Inclusion criteria: neuropsychiatric patients underwent rTMS; studies assessed depressive symptom severity; psychological tasks or interventions were administered during rTMS, or intentionally did not include a wash-out period. Of 8442 hits, 20 studies combined rTMS with aerobic exercise, bright light therapy, cognitive training or reactivation, psychotherapy, sleep deprivation, or a psychophysical task. Meta-analyses with random effects models pooled the efficacy of these combinations, based on change scores on depressive severity scales. The effect size was large and therapeutic for uncontrolled pretest-posttest comparisons (17 studies, 20 datasets, g=-1.91, SE=0.45, 95%CI= -2.80 to -1.03, p<0.01); medium when studies compared active combinations with sham rTMS plus active psychological methods (8 studies, g=-0.55, SE=0.14, 95%CI= -0.82 to -0.28, p<0.01); and non-significant when active combinations were compared with active rTMS plus sham psychological methods (4 studies, p= 0.96). These findings suggest that the antidepressant efficacy of combining rTMS with psychological methods is promising, but not an improvement over rTMS alone.
目前优化重复经颅磁刺激(rTMS)对抑郁症状疗效的方法主要集中在个性化目标和参数上。但在这三四十分钟的治疗过程中应该发生什么仍未得到充分研究。具体问题包括:有证据表明大脑状态会调节大脑对刺激的反应,以及通过同时使用经颅磁刺激和心理治疗方法来提高抗抑郁疗效的可能性。因此,我们根据PRISMA-ScR指南进行了范围界定综述和荟萃分析,以汇集在心理任务或干预期间实施经颅磁刺激的研究。检索了从开始到 2024 年 7 月 10 日的 PubMed 和 Web of Science 数据库。纳入标准:神经精神疾病患者接受经颅磁刺激;研究评估了抑郁症状的严重程度;在经颅磁刺激期间进行了心理任务或干预,或有意不包括冲洗期。在8442个点击中,有20项研究将经颅磁刺激与有氧运动、强光疗法、认知训练或再激活、心理治疗、睡眠剥夺或心理物理任务相结合。根据抑郁严重程度量表的评分变化,采用随机效应模型进行的元分析汇集了这些组合的疗效。在无对照的试验前-试验后比较中,效应大小较大且具有治疗作用(17 项研究,20 个数据集,g=-1.91,SE=0.45,95%CI=-2.80 至-1.03,p<0.01);在将活性组合与假经颅磁刺激加活性心理方法进行比较的研究中,效应大小为中等(8 项研究,g=-0.55,SE=0.14,p<0.01)。55,SE=0.14,95%CI= -0.82至-0.28,p<0.01);当活性组合与活性经颅磁刺激加假心理方法进行比较时,活性组合不显著(4项研究,p= 0.96)。这些研究结果表明,经颅磁刺激与心理方法相结合的抗抑郁疗效是有希望的,但与单独经颅磁刺激相比并无改善。

Background: Recent studies have intensively explored the potential antidepressant effects of psilocybin. However, important variables such as previous experience, repeated administration, setting and sex remain underexplored. This study describes the acute psilocybin experience and long-term effects in a small sample of healthy individuals.Methods: In a double-blind, placebo-controlled, cross-over study, 40 healthy participants (20 females, mean age 38, sd 8) received two doses of psilocybin 0.26 mg/kg per os at least 56 days apart (mean 354 days) in two study arms (EEG and fMRI). Near half of participants had experience with psychedelics. The Altered State of Consciousness Scale (ASC) and a visual analogue scale (VAS) on emotional valence of the phenomenology assessed acute phenomenology. The Persisting Effects Questionnaire (PEQ) assessed long-term effects. Venous blood samples were taken to measure serum psilocin levels.Results: All results were independent of previous experience, sex, EEG or fMRI arm/setting. Acute psychedelic effects were of moderate intensity on ASC. The VAS showed mostly pleasant and fluctuating, and only one unpleasant only experience. All experiences resolved in a positive or neutral state at the end of the session. Psilocybin induced sustained positive effects on all domains of the PEQ, with negligible negative effects. Oceanic Boundlessness and Visual Restructuralization were associated with positive effects on PEQ. Contrary to expectations, Dread of Ego Dissolution, typically associated with fearful experiences, was not associated with PEQ negative outcomes. The type of experience (pleasant or mixed) did not correlate with the intensity or direction of the lasting effect; however, peak experiences culminating in a positive mood were associated with positive long-term effects.Conclusion: In our sample repeated administration of psilocybin to healthy volunteers, induces positive, lasting effects. This underscores the psychological safety of psilocybin in a laboratory setting and supports its repeated use in clinical trials. In particular, challenging or anxiety-provoking experiences in controlled environments did not lead to adverse long-term outcomes.
背景:最近的研究深入探讨了迷幻药的潜在抗抑郁作用。然而,一些重要的变量,如先前的经历、重复给药、环境和性别等,仍未得到充分探讨。本研究描述了一小部分健康人的急性迷幻药体验和长期效果:在一项双盲、安慰剂对照、交叉研究中,40 名健康参与者(20 名女性,平均年龄 38 岁,sd 8)在两个研究臂(脑电图和 fMRI)中接受了两次剂量为每盎司 0.26 毫克/千克的迷幻剂,每次间隔至少 56 天(平均 354 天)。近一半的参与者曾服用过迷幻药。意识状态改变量表(ASC)和现象情绪价位视觉模拟量表(VAS)对急性现象进行了评估。持续效应问卷(PEQ)评估长期效应。抽取静脉血样本测量血清中的西洛辛水平:所有结果都与先前的经历、性别、脑电图或 fMRI 臂/设置无关。急性迷幻剂对 ASC 的影响强度适中。VAS 显示,大部分体验是愉快和波动的,只有一次体验是不愉快的。在疗程结束时,所有体验都以积极或中性的状态结束。迷幻药对 PEQ 的所有领域都产生了持续的积极影响,负面影响可以忽略不计。海洋无边界和视觉重组与对 PEQ 的积极影响有关。与预期相反,通常与恐惧体验相关的 "自我解体恐惧 "与 PEQ 负面结果无关。体验的类型(令人愉快或喜忧参半)与持久效果的强度或方向无关;然而,以积极情绪为高潮的峰值体验与积极的长期效果有关:结论:在我们的样本中,对健康志愿者反复施用迷幻剂会产生积极而持久的效果。这强调了在实验室环境中使用迷幻药的心理安全性,并支持在临床试验中重复使用迷幻药。特别是,在受控环境中具有挑战性或令人焦虑的体验不会导致不良的长期结果。

Patients with mood or psychotic disorders have high rates of unplanned readmission, and predicting readmission likelihood may guide discharge decisions. In this retrospective, multi-site study, we assess the predictive power of various structured variables from electronic health records for all-cause readmission in each site separately and evaluate the generalizability of the in-site prediction models across sites. We find that the set of relevant predictors vary significantly across. For example, length of stay is strongly predictive of readmission at only three out of the four sites. We also find a general lack of cross-site generalizability of the in-site prediction models, with in-site predictions having an average F1 score of 0.666, compared to an average F1 score of 0.551 for cross-site predictions. The generalizability cannot be improved even after adjusting for differences in the distributions of predictors. These results indicate that, with this set of predictors, fitting individual models at each site is necessary to achieve reasonable prediction accuracy. Additionally, they suggest that more sophisticated predictors variables or predictive algorithms are needed to develop generalizable models capable of extracting robust insights into the root causes of early psychiatric readmissions.
情绪障碍或精神障碍患者的计划外再入院率很高,预测再入院的可能性可以为出院决策提供指导。在这项多机构回顾性研究中,我们分别评估了各机构电子健康记录中各种结构化变量对全因再入院的预测能力,并评估了机构内预测模型在不同机构间的通用性。我们发现,相关的预测因子在不同地点之间存在很大差异。例如,在四个地点中,只有三个地点的住院时间对再入院具有很强的预测作用。我们还发现站内预测模型普遍缺乏跨站通用性,站内预测的平均 F1 得分为 0.666,而跨站预测的平均 F1 得分为 0.551。即使对预测因子的分布差异进行调整,也无法提高泛化能力。这些结果表明,对于这组预测因子,有必要在每个站点拟合单独的模型,以达到合理的预测精度。此外,这些结果还表明,需要更复杂的预测变量或预测算法,才能开发出具有普适性的模型,从而对精神病患者早期再入院的根本原因提出有力的见解。
