    背景:评估首发精神病(FEP)患者的难治性精神分裂症(TRS)风险的临床工具将有助于早期发现TRS,并克服了开始TRS药物治疗长达5年的延迟。
    目的:开发并评估在常规临床实践中预测TRS风险的模型。
    方法:我们使用来自英国的两个FEP队列(GAP和AESOP-10)的数据来开发并内部验证一个预后模型,该模型支持在FEP诊断后不久识别TRS高危患者。使用社会人口统计学和临床预测因子,基于惩罚逻辑回归建立了TRS风险预测模型,使用多个插补处理丢失的数据。内部验证是通过自举进行的,获得乐观调整后的模型性能估计。与临床医生进行访谈和焦点小组,以建立临床相关的风险阈值,并了解该模型的可接受性和感知效用。
    结果:我们在预测模型中纳入了7个因子,这些因子主要在FEP患者的临床实践中进行评估。该模型以合理的准确性预测了1081例患者的治疗抵抗;模型的C统计量在收缩前为0.727(95%CI0.723-0.732),在乐观调整后为0.687。校准是良好的(预期/观察到的比率:0.999;校准大:0.000584)调整后乐观。
    结论:我们开发并内部验证了一个具有相当好的预测指标的预测模型。临床医生,患者和护理人员参与了发育过程.需要对该工具进行外部验证,然后进行共同设计方法,以支持早期干预服务的实施。
    BACKGROUND: A clinical tool to estimate the risk of treatment-resistant schizophrenia (TRS) in people with first-episode psychosis (FEP) would inform early detection of TRS and overcome the delay of up to 5 years in starting TRS medication.
    OBJECTIVE: To develop and evaluate a model that could predict the risk of TRS in routine clinical practice.
    METHODS: We used data from two UK-based FEP cohorts (GAP and AESOP-10) to develop and internally validate a prognostic model that supports identification of patients at high-risk of TRS soon after FEP diagnosis. Using sociodemographic and clinical predictors, a model for predicting risk of TRS was developed based on penalised logistic regression, with missing data handled using multiple imputation. Internal validation was undertaken via bootstrapping, obtaining optimism-adjusted estimates of the model\'s performance. Interviews and focus groups with clinicians were conducted to establish clinically relevant risk thresholds and understand the acceptability and perceived utility of the model.
    RESULTS: We included seven factors in the prediction model that are predominantly assessed in clinical practice in patients with FEP. The model predicted treatment resistance among the 1081 patients with reasonable accuracy; the model\'s C-statistic was 0.727 (95% CI 0.723-0.732) prior to shrinkage and 0.687 after adjustment for optimism. Calibration was good (expected/observed ratio: 0.999; calibration-in-the-large: 0.000584) after adjustment for optimism.
    CONCLUSIONS: We developed and internally validated a prediction model with reasonably good predictive metrics. Clinicians, patients and carers were involved in the development process. External validation of the tool is needed followed by co-design methodology to support implementation in early intervention services.

    当医师协助死亡(在本文中称为医疗协助死亡或MAiD)可用于患有精神障碍的个体作为唯一的潜在医疗条件(MD-SUMC)时,边缘性人格障碍(BPD)患者经常要求MAiD。精神科医生和其他临床医生必须准备好评估和管理这些请求。
    本文的目的是定义何时应将BPD患者视为无法治愈的,治疗耐药障碍,并为临床医生提供一种评估和管理BPD患者对MAiD的要求的方法。
    这篇透视论文通过使用已发表的,不可补救性的权威定义,包括与不可补救性评估相关的值得注意的系统和/或荟萃分析评论。
    临床医生必须了解在其管辖范围内授予MAiD的资格要求,以便他们能够适当地为评估过程做好准备。对特定人的痛苦的不可忍受性的评估来自与患者进行广泛的对话;然而,应更客观可靠地评估患者是否患有无法治愈的BPD.在疾病严重程度的背景下,对评估BPD不可治愈性的系统方法进行了审查。治疗抗性和不可逆性。
    除了表征不可补救性之外,本文还介绍了接受MAiD评估过程的BPD患者自杀风险的评估和管理.
    UNASSIGNED: When physician assisted dying (referred to as Medical Assistance in Dying or MAiD in this article) is available for individuals with mental disorders as the sole underlying medical condition (MD-SUMC), patients with borderline personality disorder (BPD) frequently request MAiD. Psychiatrists and other clinicians must be prepared to evaluate and manage these requests.
    UNASSIGNED: The purposes of this paper are to define when patients with BPD should be considered to have an irremediable, treatment resistant disorder and provide clinicians with an approach to assess and manage their patients with BPD making requests for MAiD.
    UNASSIGNED: This perspective paper developed the authors\' viewpoint by using a published, authoritative definition of irremediability and including noteworthy systematic and/or meta-analytic reviews related to the assessment of irremediability.
    UNASSIGNED: The clinician must be aware of the eligibility requirements for granting MAiD in their jurisdiction so that they can appropriately prepare themselves and their patients for the assessment process. The appraisal of the intolerability of the specific person\'s suffering comes from having an extensive dialogue with the patient; however, the assessment of whether the patient has irremediable BPD should be more objectively and reliably determined. A systematic approach to the assessment of irremediability of BPD is reviewed in the context of the disorder\'s severity, treatment resistance and irreversibility.
    UNASSIGNED: In addition to characterizing irremediability, this paper also addresses the evaluation and management of suicide risk for patients with BPD undergoing the MAiD assessment process.

    已提出功能连接静息状态功能磁共振成像来预测精神分裂症的抗精神病药物治疗反应。然而,只有少数前瞻性研究对首次用药的精神分裂症患者的静息状态功能磁共振成像基线数据进行了后续治疗反应方面的研究.数据驱动的概念化和测量功能连接模式的方法差异很大,无模型,逐体素,全脑分析技术很少。这里,我们应用这样的方法,称为连接一致性映射到从患有首发精神病的亚洲样本(n=60)获得的静息状态功能磁共振成像数据,在药物治疗之前。采用纵向设计,静息状态功能磁共振成像后12个月,我们根据心理测量测试将患者分为两组:治疗反应和治疗抵抗.接下来,我们比较了两组基线时静息态功能磁共振成像数据的连通性一致性图.我们已经在包括左海马的网络中发现了持续较高的功能连通性,双侧岛和颞极。这些数据驱动的新发现可以帮助研究人员考虑新的感兴趣区域,并促进生物标志物的开发,以便及早识别治疗耐药的精神分裂症患者。在治疗之前和第一次精神病发作时。
    Functional connectivity resting-state functional magnetic resonance imaging has been proposed to predict antipsychotic treatment response in schizophrenia. However, only a few prospective studies have examined baseline resting-state functional magnetic resonance imaging data in drug-naïve first-episode schizophrenia patients with regard to subsequent treatment response. Data-driven approaches to conceptualize and measure functional connectivity patterns vary broadly, and model-free, voxel-wise, whole-brain analysis techniques are scarce. Here, we apply such a method, called connectivity concordance mapping to resting-state functional magnetic resonance imaging data acquired from an Asian sample (n = 60) with first-episode psychosis, prior to pharmaceutical treatment. Using a longitudinal design, 12 months after the resting-state functional magnetic resonance imaging, we measured and classified patients into two groups based on psychometric testing: treatment responsive and treatment resistant. Next, we compared the two groups\' connectivity concordance maps that were derived from the resting-state functional magnetic resonance imaging data at baseline. We have identified consistently higher functional connectivity in the treatment-resistant group in a network including the left hippocampus, bilateral insula and temporal poles. These data-driven novel findings can help researchers to consider new regions of interest and facilitate biomarker development in order to identify treatment-resistant schizophrenia patients early, in advance of treatment and at the time of their first psychotic episode.

    目的:研究艾氯胺酮鼻喷雾剂(ESK)加口服抗抑郁药(OAD)与OAD加安慰剂鼻喷雾剂(PBO)对蒙哥马利-奥斯贝格抑郁量表(MADRS)和9项患者健康问卷(PHQ-9)评分在成人难治性抑郁症(TRD)中的相关性。
    方法:来自TRANSFORM-1和TRANSFORM-2的数据(两个类似设计,随机化,分析了主动控制的TRD研究)和SUSTAIN-1(复发预防研究)。使用协方差分析比较PHQ-9总分从基线的平均变化的组差异。使用简单参数评估TRANSFORM-1/TRANSFORM-2的MADRS和PHQ-9总分之间的关联,非参数,和多元回归模型。
    结果:在TRANSFORM-1/TRANSFORM-2(ESK+OAD,n=343;OAD+PBO,n=222),ESK+OAD的基线PHQ-9平均评分为20.4分,OAD+PBO(重度抑郁症)为20.6分.在第28天,PHQ-9评分与基线相比的最小二乘均值变化(SE)存在显着差异(-12.8[0.46]vs-10.3[0.53],P<.001)和PHQ-9评分的临床实质性变化(≥6分;77.1%vs64%,P<.001)在ESK+OAD和OAD+PBO组中,分别。观察到MADRS和PHQ-9之间的非线性关系;总分显示出随着时间的推移相关性增加。在SUSTAIN-1中,57.3%接受ESK+OAD(n=89)和44.2%接受OAD+PBO(n=86)的患者在维持治疗终点时保持缓解状态(PHQ-9评分≤4)(P=.044)。
    结论:在患有TRD的成年人中,ESK+OAD显著改善抑郁症状的严重程度,与OAD+PBO相比,更多的患者根据PHQ-9在抑郁症状方面实现了有临床意义的变化。PHQ-9结果与临床医生评估的MADRS结果一致。
    背景:ClinicalTrials.gov:NCT02417064,NCT02418585,NCT02493868。
    OBJECTIVE: To examine the effect of esketamine nasal spray (ESK) plus newly initiated oral antidepressant (OAD) versus OAD plus placebo nasal spray (PBO) on the association between Montgomery-Åsberg Depression Rating Scale (MADRS) and 9-item Patient Health Questionnaire (PHQ-9) scores in adults with treatment-resistant depression (TRD).
    METHODS: Data from TRANSFORM-1 and TRANSFORM-2 (two similarly designed, randomized, active-controlled TRD studies) and SUSTAIN-1 (relapse prevention study) were analyzed. Group differences for mean changes in PHQ-9 total score from baseline were compared using analysis of covariance. Associations between MADRS and PHQ-9 total scores from TRANSFORM-1/TRANSFORM-2 were assessed using simple parametric, nonparametric, and multiple regression models.
    RESULTS: In TRANSFORM-1/TRANSFORM-2 (ESK + OAD, n = 343; OAD + PBO, n = 222), baseline PHQ-9 mean scores were 20.4 for ESK + OAD and 20.6 for OAD + PBO (severe depression). At day 28, significant group differences were observed in least squares mean change (SE) in PHQ-9 scores from baseline (-12.8 [0.46] vs -10.3 [0.53], P < .001) and in clinically substantial change in PHQ-9 scores (≥6 points; 77.1% vs 64%, P < .001) in ESK + OAD and OAD + PBO groups, respectively. A nonlinear relationship between MADRS and PHQ-9 was observed; total scores demonstrated increased correlation over time. In SUSTAIN-1, 57.3% of patients receiving ESK + OAD (n = 89) versus 44.2% receiving OAD + PBO (n = 86) retained remission status (PHQ-9 score ≤4) at maintenance treatment end point (P = .044).
    CONCLUSIONS: In adults with TRD, ESK + OAD significantly improved severity of depressive symptoms, and more patients achieved clinically meaningful changes in depressive symptoms based on PHQ-9, versus OAD + PBO. PHQ-9 outcomes were consistent with those of clinician-rated MADRS.

    神经影像学的最新进展提高了我们对精神分裂症潜在生物学机制的理解。然而,难治性精神分裂症(TRS)的神经影像学检查结果尚不清楚.在本研究中,我们旨在通过使用MRICloud方法比较TRS和非TRS患者的神经解剖区域,探索精神分裂症患者可能与治疗抵抗相关的潜在神经解剖区域.共有33名精神分裂症患者(符合DSM5精神分裂症诊断标准)被纳入研究。将患者分为TRS(n=18)和非TRS(n=15)组,所有患者都接受了MRI检查。使用MRICloud方法比较TRS和非TRS患者的神经解剖区域。使用阳性和阴性综合征量表(PANSS)测量疾病严重程度。有趣的是,与非TRS患者相比,在TRS患者中发现有统计学意义的更大的左侧Collosum(CC)厚度.很明显,需要进一步研究比较TRS患者与非TRS患者,这些研究应该集中在call体的回路上,这些回路被认为在治疗抵抗中起作用。还需要进一步的纵向研究来补充横断面研究,在具有明确定义的TRS标准的患者中使用多模态成像方法。
    Recent developments in neuroimaging have improved our understanding of the biological mechanisms underlying schizophrenia. However, neuroimaging findings in treatment-resistant schizophrenia (TRS) remain unclear. In the present study, we aimed to explore potential neuroanatomical regions that may be associated with treatment resistance in schizophrenia patients by comparing neuroanatomical regions of TRS and non-TRS patients using the MRICloud method. A total of 33 schizophrenia patients (meeting DSM 5 diagnostic criteria for schizophrenia) were included in the study. Patients were dichotomized into TRS (n = 18) and non-TRS (n = 15) groups, and all patients underwent MRI. Neuroanatomical regions of TRS and non-TRS patients were compared using the MRICloud method. Disease severity was measured using the Positive and Negative Syndrome Scale (PANSS). Interestingly, a statistically significant greater left Corpus Collosum (CC) thickness was found in TRS patients compared to non-TRS patients. It is clear that further studies comparing TRS patients with non-TRS patients are needed, and these studies should focus on the circuits in the corpus callosum that are thought to play a role in treatment resistance. Further longitudinal studies are also needed to complement the cross-sectional studies, using a multimodal imaging approach in the patients with clearly defined TRS criteria.

    目的:探讨苯二氮卓类药物对难治性重度抑郁症(TR-MDD)患者重复经颅磁刺激(rTMS)疗效的影响。
    方法:这是一项回顾性研究,比较了服用苯二氮卓类药物的患者(n=59)和未服用苯二氮卓类药物的患者(n=136)的rTMS治疗结果。参与者完成了HAM-A,基线和治疗结束时的HAM-D17、MADRS和ZUNG。
    结果:在rTMS治疗期间服用苯二氮卓类药物的患者在部分反应方面没有任何差异,与未使用苯二氮卓类药物治疗的患者相比,缓解或缓解率。从基线到治疗后,两组的抑郁和焦虑评分均显着下降(p<0.0001)。
    结论:同时服用苯二氮卓类药物对rTMS治疗TRD的疗效无影响,与以往的研究相反。
    OBJECTIVE: To investigate the effect of concomitant use of benzodiazepines on the efficacy of repetitive transcranial magnetic stimulation (rTMS) in patients with treatment-resistant major depressive disorder (TR-MDD).
    METHODS: This is a retrospective study comparing rTMS treatment outcomes between patients taking benzodiazepines (n = 59) and those who were not (n = 136). Participants completed the HAM-A, HAM-D17, MADRS and ZUNG at baseline and at the end of treatment.
    RESULTS: Patients taking benzodiazepines during rTMS treatment did not show any difference in partial response, response or remission rates compared to patients not treated with benzodiazepines. There was a significant decrease (p < .0001) in depression and anxiety scores from baseline to post-treatment among both groups.
    CONCLUSIONS: Concomitant benzodiazepine treatment had no effect on the efficacy of rTMS treatment of TRD, contrary to previous research.

    强迫症(OCD)是一种复杂且通常难以治疗的疾病。药物和心理治疗干预通常与次优结果相关,40-60%的患者对一线治疗耐药,因此很少有治疗选择。强迫症是由皮质内的异常神经回路支撑的,纹状体,和丘脑大脑网络。考虑到强迫症症状背后的神经电路损伤,神经刺激疗法提供了以个性化方式调节精神病理学的机会。此外,通过探测病理神经网络,可以提高对疾病状态的理解。
    这个角度讨论了TMS和DBS疗法的临床疗效,治疗访问选项,以及管理患者的注意事项和挑战。讨论了最近的科学进展,专注于神经电路和生物心理社会方面。为今后的研究提供了转化性建议和建议。
    有强有力的证据支持TMS和DBS作为治疗耐药性强迫症患者的有效疗法,并有良好的安全性和良好的健康经济数据支持。尽管慢性和重度强迫症患者非常需要替代疗法,监管机构和精神病学界对神经刺激疗法的抵制仍然存在。作者主张在具有适当临床资源的专门场所,为治疗耐药的强迫症患者提供更多的TMS和DBS,特别是考虑到辅助和后续护理。此外,连接体靶向显示了对症状改善的强大预测能力,并在推进个性化护理方面具有潜力。
    UNASSIGNED: Obsessive compulsive disorder (OCD) represents a complex and often difficult to treat disorder. Pharmacological and psychotherapeutic interventions are often associated with sub-optimal outcomes, and 40-60% of patients are resistant to first line therapies and thus left with few treatment options. OCD is underpinned by aberrant neurocircuitry within cortical, striatal, and thalamic brain networks. Considering the neurocircuitry impairments that underlie OCD symptomology, neurostimulation therapies provide an opportunity to modulate psychopathology in a personalized manner. Also, by probing pathological neural networks, enhanced understanding of disease states can be obtained.
    UNASSIGNED: This perspective discusses the clinical efficacy of TMS and DBS therapies, treatment access options, and considerations and challenges in managing patients. Recent scientific progress is discussed, with a focus on neurocircuitry and biopsychosocial aspects. Translational recommendations and suggestions for future research are provided.
    UNASSIGNED: There is robust evidence to support TMS and DBS as an efficacious therapy for treatment resistant OCD patients supported by an excellent safety profile and favorable health economic data. Despite a great need for alternative therapies for chronic and severe OCD patients, resistance toward neurostimulation therapies from regulatory bodies and the psychiatric community remains. The authors contend for greater access to TMS and DBS for treatment resistant OCD patients at specialized sites with appropriate clinical resources, particularly considering adjunct and follow-up care. Also, connectome targeting has shown robust predictive ability of symptom improvements and holds potential in advancing personalized neurostimulation therapies.

    背景:结节病是一种多系统肉芽肿性疾病,表现和临床过程多种多样。与结节病预后相关的皮肤表现和合并症仍未得到充分研究。方法:根据ICD-10-CM代码D86.3,在约翰霍普金斯医院对18岁以上的患者进行EPIC查询,诊断为皮肤结节病数据来自2015年至2020年的240名患者的基于人群的样本。结果:共有240例患者被纳入队列研究。平均(SD)年龄为43.76(11.72)岁,30%的参与者是男性;76.25%的患者被确定为黑人,19.58%为白色,和其他4.17%。缓解期患者的平均发病年龄明显高于进展期(47±12vs.40±10,p=0.0005);49%的黑人患者经历了进行性结节病,而白人患者为32.6%(p=0.028)。进展性疾病与狼疮的存在相关(aOR=3.29,95%CI,1.60-6.77)和至少一种自身免疫性共病(aOR6.831,95%CI1.819-11.843)。结论:在控制患者人口统计学时,狼疮和至少一种自身免疫性疾病的存在与进行性皮肤结节病有关。
    Background: Sarcoidosis is a multisystem granulomatous disease with a wide variety of presentations and clinical courses. Cutaneous manifestations and comorbidities associated with sarcoid prognosis remain understudied. Methods: An EPIC query was run for patients age 18+ at the Johns Hopkins Hospital with a diagnosis of sarcoidosis of the skin according to the ICD-10-CM code D86.3. Data were obtained from a population-based sample of 240 patients from 2015 to 2020. Results: A total of 240 patients were included in the cohort study. The mean (SD) age was 43.76 (11.72) years, and 30% of participants were male; 76.25% of patients identified as black, 19.58% as white, and 4.17% as other. The average age of onset in remissive patients was significantly higher than progressive (47 ± 12 vs. 40 ± 10, p = 0.0005); 49% of black patients experienced progressive sarcoid compared to 32.6% of white patients (p = 0.028). Progressive disease was associated with the presence of lupus pernio (aOR = 3.29, 95% CI, 1.60-6.77) and at least one autoimmune comorbidity (aOR 6.831, 95% CI 1.819-11.843). Conclusions: When controlling for patient demographics, lupus pernio and the presence of at least one autoimmune condition were associated with progressive cutaneous sarcoidosis.

    亚麻醉氯胺酮是一种快速作用的抗抑郁药,也被发现可以改善患有难治性抑郁症(TRD)的成年患者的神经认知能力。临时证据表明,氯胺酮可能引起海马体积的变化,更大的治疗前体积可能与积极的临床结果有关。这里,我们研究了连续氯胺酮治疗对海马亚场体积的影响,以及治疗前亚场体积与抑郁症状和神经认知能力变化之间的关系.
    TRD患者(N=66;31M/35F;年龄=39.5±11.1岁)在2周内接受了4次氯胺酮输注(0.5mg/kg)。结构核磁共振扫描,美国国立卫生研究院工具箱(NIHT)认知电池,在基线时收集汉密尔顿抑郁量表(HDRS),第一次和第四次氯胺酮输注后24小时,治疗后5周。在一个时间点收集32个年龄和性别匹配的健康对照(HC;17M/15F;年龄=35.03±12.2岁)的相同数据。整个海马体积校正的子场(CA1/CA3/CA4/下膜/分子层/GC-ML-DG)体积随时间进行比较,在治疗汇款人/非汇款人之间,以及患者和HCs使用线性回归模型。还测试了治疗前子场体积与临床和认知结果之间的关系。所有分析包括Bonferroni校正。
    患者的治疗前左CA4(p=0.004)和GC较小。ML.与HC相比,DG(p=0.004)体积,但氯胺酮治疗后的子场体积保持稳定(均p>0.05)。治疗前或海马亚区体积随时间的变化未显示出缓解状态的变化,也与抑郁症状相关(p>0.05)。治疗前左CA4与单次输注氯胺酮(p=0.0003)和连续输注氯胺酮(p=0.005)后处理速度的提高呈负相关。左侧GC。ML.DG也与单次输注后提高的处理速度呈负相关(p=0.001)。正确的治疗前CA3与随访时列表排序工作记忆的变化呈正相关(p=0.0007)。
    这些结果提供了新的证据,表明基线时的海马子场体积可能是氯胺酮治疗TRD后神经认知改善的生物标志物。相比之下,治疗前亚场体积和亚场体积的变化与氯胺酮相关的抑郁症状改善的关系可忽略不计.
    UNASSIGNED: Subanesthetic ketamine is a rapidly acting antidepressant that has also been found to improve neurocognitive performance in adult patients with treatment resistant depression (TRD). Provisional evidence suggests that ketamine may induce change in hippocampal volume and that larger pre-treatment volumes might be related to positive clinical outcomes. Here, we examine the effects of serial ketamine treatment on hippocampal subfield volumes and relationships between pre-treatment subfield volumes and changes in depressive symptoms and neurocognitive performance.
    UNASSIGNED: Patients with TRD (N = 66; 31M/35F; age = 39.5 ± 11.1 years) received four ketamine infusions (0.5 mg/kg) over 2 weeks. Structural MRI scans, the National Institutes of Health Toolbox (NIHT) Cognition Battery, and Hamilton Depression Rating Scale (HDRS) were collected at baseline, 24 h after the first and fourth ketamine infusion, and 5 weeks post-treatment. The same data was collected for 32 age and sex matched healthy controls (HC; 17M/15F; age = 35.03 ± 12.2 years) at one timepoint. Subfield (CA1/CA3/CA4/subiculum/molecular layer/GC-ML-DG) volumes corrected for whole hippocampal volume were compared across time, between treatment remitters/non-remitters, and patients and HCs using linear regression models. Relationships between pre-treatment subfield volumes and clinical and cognitive outcomes were also tested. All analyses included Bonferroni correction.
    UNASSIGNED: Patients had smaller pre-treatment left CA4 (p = 0.004) and GC.ML.DG (p = 0.004) volumes compared to HC, but subfield volumes remained stable following ketamine treatment (all p > 0.05). Pre-treatment or change in hippocampal subfield volumes over time showed no variation by remission status nor correlated with depressive symptoms (p > 0.05). Pre-treatment left CA4 was negatively correlated with improved processing speed after single (p = 0.0003) and serial ketamine infusion (p = 0.005). Left GC.ML.DG also negatively correlated with improved processing speed after single infusion (p = 0.001). Right pre-treatment CA3 positively correlated with changes in list sorting working memory at follow-up (p = 0.0007).
    UNASSIGNED: These results provide new evidence to suggest that hippocampal subfield volumes at baseline may present a biomarker for neurocognitive improvement following ketamine treatment in TRD. In contrast, pre-treatment subfield volumes and changes in subfield volumes showed negligible relationships with ketamine-related improvements in depressive symptoms.
