Objective

To develop and assess the efficacy of a rehabilitation–cognition integrated care (RCIC) program for elderly patients with lower limb fractures and mild-to-moderate cognitive impairment.

Methods

A total of 128 eligible patients during January 2023 to December 2024 were randomly allocated to conventional (n = 64) or integrated care group (n = 64). Both groups received 12 weeks of intervention. Outcomes, including Fugl-Meyer Assessment (FMA), Berg Balance Scale (BBS), Montreal Cognitive Assessment (MoCA), Functional Independence Measure (FIM), and Hospital Anxiety and Depression Scale (HADS) scores, were compared. Serum neurotrophic and neuroinflammatory markers were analyzed pre- and post-intervention. Complications, fall recurrence rates, and nursing satisfaction were recorded.

Results

Post-intervention, both groups showed improved FMA, BBS, and FIM scores, with significantly greater improvement in the integrated care group (p < 0.05). HADS-Anxiety (HADS-A) and HADS-Depression (HADS-D) scores decreased significantly more in the integrated care group (p < 0.05). The integrated care group demonstrated higher MoCA scores versus both its own baseline and the conventional care group post-intervention (p < 0.05). Serum BDNF and GDNF levels increased significantly in the integrated care group compared to both time-matched controls and its baseline (p < 0.05), while S100-β and IL-6 levels decreased significantly (p < 0.05). The integrated care group had lower overall complication rates (p < 0.05), comparable fall recurrence (p > 0.05), and higher nursing satisfaction (p < 0.05).

Conclusion

The RCIC program significantly enhances motor function, balance, cognition, and psychological status while reducing complications and improving satisfaction in elderly fracture patients with cognitive impairment.

目的：探讨康复-认知综合护理（RCIC）方案对老年下肢骨折伴轻中度认知功能障碍患者的疗效。方法：2023年1月至2024年12月，128例符合条件的患者随机分为常规组（n = 64）和综合护理组（n = 64）。两组均接受12周的干预。结果包括Fugl-Meyer评估（FMA）、Berg平衡量表（BBS）、蒙特利尔认知评估（MoCA）、功能独立性测量（FIM）和医院焦虑和抑郁量表（HADS）评分进行比较。分析干预前后血清神经营养和神经炎症标志物。记录并发症、跌倒复发率及护理满意度。结果：干预后，两组患者FMA、BBS、FIM评分均有改善，其中综合护理组改善更显著（p < 0.05）。综合护理组的hads -焦虑（HADS-A）和hads -抑郁（HADS-D）评分下降幅度明显大于综合护理组（p < 0.05）。综合护理组干预后的MoCA评分高于其自身基线和常规护理组（p < 0.05）。与时间匹配对照组及其基线相比，综合护理组血清BDNF和GDNF水平显著升高（p < 0.05），而S100-β和IL-6水平显著降低（p < 0.05）。综合护理组总体并发症发生率较低（p < 0.05），相对跌倒复发率较低（p < 0.05），护理满意度较高（p < 0.05）。结论：RCIC方案可显著提高老年骨折合并认知功能障碍患者的运动功能、平衡、认知和心理状态，减少并发症，提高满意度。

Introduction

Prenatal substance exposure is an increasing problem that has been linked to multiple neurodevelopmental impairments and alterations to brain functional connectivity.

Methods

Behavioral scores and functional network correlation data were obtained from the Adolescent Brain Cognitive Development^SM (ABCD) Study. First, behavioral scores based on the child behavioral checklist were tested for associations with prenatal exposure to several substances along with demographic data. Then differences in resting-state functional networks were assessed based on prenatal substance exposure. Third, we assessed the impact of resting-state functional networks on behavioral scores. A linear regression was used for all these analyses, and a false discovery rate < 0.05 was considered significant.

Results

Based on the selection criteria, 6674 subjects were included in the analysis. Prenatal tobacco exposure (PTE), prenatal marijuana exposure, household income, and food insecurity were associated with worse behavioral scores. Additionally, PTE was significantly associated with increased connectivity between the default mode network (DMN) and dorsal attention network (DAN) and decreased intra-network connectivity within the DAN. Finally, there were five CBCL scales that were associated with differences in network connectivity.

Conclusion

Taken together, these results suggest PTE to be associated with multiple functional networks, including those associated with several CBCL scales.

产前物质暴露是一个日益严重的问题，与多种神经发育障碍和脑功能连接的改变有关。方法：从青少年大脑认知发展（ABCD）研究中获取行为评分和功能网络相关数据。首先，基于儿童行为检查表的行为得分与产前接触几种物质以及人口统计数据的关系进行了测试。然后根据产前物质暴露评估静息状态功能网络的差异。第三，我们评估了静息状态功能网络对行为评分的影响。所有这些分析都使用线性回归，错误发现率< 0.05被认为是显著的。结果：根据入选标准，共纳入受试者6674例。产前烟草暴露（PTE）、产前大麻暴露、家庭收入和食品不安全与较差的行为得分有关。此外，PTE与默认模式网络（DMN）和背侧注意网络（DAN）之间的连通性增加以及DAN内网络内连通性降低显著相关。最后，有五个CBCL量表与网络连通性的差异相关。结论：综上所述，这些结果表明PTE与多种功能网络相关，包括与几种CBCL量表相关的功能网络。

Introduction

Although visual mental imagery has been widely researched, a lack of valid measures in Persian-speaking populations has limited cross-cultural, developmental, and clinical research on imagery vividness and its role in reality monitoring.

Methods

We translated, culturally adapted, and psychometrically validated the Persian version of the Vividness of Visual Imagery Questionnaire-2 (VVIQ-Pr2) in this cross-sectional study. Our sample was 630 Persian speakers. Participants completed the VVIQ-Pr2 together with the Vividness of Motor Imagery Questionnaire (VMIQ-2), the Spontaneous Use of Imagery Scale (SUIS), the Generalized Anxiety Disorder-7 (GAD-7), and the Ten Item Personality Inventory (TIPI). Confirmatory factor analysis and multi-group modeling were also conducted.

Results

Confirmatory factor analysis supported a unidimensional structure with correlated residuals demonstrating excellent model fit. The scale showed strong internal consistency. Convergent validity was confirmed by positive correlations with VMIQ-2 and SUIS, while discriminant validity was supported by negligible associations with anxiety and all Heterotrait–Monotrait ratios falling below recommended thresholds. Scalar measurement invariance across gender was established with females scoring slightly higher than males. Finally, age modeling revealed a slight decrease in the vividness of imagery from adolescence to early adulthood, followed by relative stability after that.

Conclusion

The VVIQ-Pr2 is a psychometrically reliable assessment tool for Persian speakers. In addition to operationalizing subjective visual experience in theories on reality monitoring, it may facilitate future cross-cultural and developmental research.

虽然视觉心理意象已被广泛研究，但在波斯语人群中缺乏有效的测量方法，限制了对意象生动性及其在现实监测中的作用的跨文化、发展和临床研究。方法：在这项横断面研究中，我们翻译、文化适应和心理测量学验证了波斯语版本的视觉意象生动度问卷-2 （VVIQ-Pr2）。我们的样本是630名波斯语使用者。参与者在完成VVIQ-Pr2的同时，还完成了运动意象生动度问卷（VMIQ-2）、自发性意象使用量表（SUIS）、广泛性焦虑障碍-7 （GAD-7）和十项人格量表（TIPI）。并进行了验证性因子分析和多组建模。结果：验证性因子分析支持一维结构，相关残差显示良好的模型拟合。量表具有较强的内部一致性。收敛效度与VMIQ-2和SUIS呈正相关，而判别效度与焦虑和所有异性状-单性状比低于推荐阈值的相关性可以忽略。性别间存在标量测量不变性，女性得分略高于男性。最后，年龄模型显示，从青春期到成年早期，意象的生动度略有下降，之后相对稳定。结论：VVIQ-Pr2是波斯语使用者心理测量学上可靠的评估工具。除了在现实监测理论中实现主观视觉经验的操作性外，它还可以促进未来的跨文化和发展研究。

Background

The U.S. population is aging with an increasing burden of Parkinson's disease (PD) and its frequent co-occurring mental health disorders. However, mortality trends related to PD and these comorbid mental health disorders among older adults remain understudied.

Objective

To examine trends in mortality due to PD and related mental health conditions among adults aged 45 and older in the United States from 1999 to 2023.

Methods

We extracted mortality data for PD and mental health-related conditions among individuals aged 45 and older from the CDC WONDER database. Age-adjusted mortality rates (AAMRs) were calculated per 100,000 persons and stratified by sex, race/ethnicity, census region, and urbanization status. Annual percentage changes (APCs) with their 95% confidence intervals (CIs) were estimated using the Joinpoint regression program.

Results

PD and its associated mental health disorders resulted in 238,378 deaths between 1999 and 2023. The AAMR increased significantly from 3.83 in 1999 to 8.49 in 2023 with an AAPC of 3.20 (p = 0.005). Males consistently showed higher AAMRs than females (overall AAMR male: 11.40 vs. female: 5.75). Non-Hispanic (NH) Whites had the highest mortality rates (8.67), while NH African Americans exhibited the lowest (4.66). Crude mortality rate was the highest among older adults (21.09), reflecting the greatest burden in this population. Similarly, the mortality rates were higher in nonmetropolitan areas (8.15) than the metropolitan areas (7.72). The highest AAMR was noted in the Midwest (9.18), with a standard deviation of 14.08 in Minnesota and 5.44 in Arizona. The majority of the deaths were recorded in nursing or long-term care facilities (52.65%).

Conclusion

The increasing trend in mortality highlights the necessity of focused preventive, diagnostic, and treatment approaches for all susceptible groups.

背景：美国人口正在老龄化，帕金森病（PD）的负担越来越重，并经常伴有精神健康障碍。然而，老年人中PD和这些共病精神健康障碍相关的死亡率趋势仍未得到充分研究。目的：研究1999年至2023年美国45岁及以上成年人PD及相关心理健康状况的死亡率趋势。方法：我们从CDC WONDER数据库中提取年龄在45岁及以上的PD和精神健康相关疾病的死亡率数据。计算每10万人的年龄调整死亡率（AAMRs），并按性别、种族/民族、人口普查地区和城市化状况分层。使用Joinpoint回归程序估计年百分比变化（APCs）及其95%置信区间（ci）。结果：1999年至2023年间，PD及其相关精神健康障碍导致238,378人死亡。AAMR由1999年的3.83增加到2023年的8.49，AAPC为3.20 （p = 0.005）。男性的AAMR始终高于女性（男性总体AAMR为11.40，女性为5.75）。非西班牙裔（NH）白人的死亡率最高（8.67），而NH非洲裔美国人的死亡率最低（4.66）。粗死亡率在老年人中最高（21.09），反映了这一人群的最大负担。同样，非大都市地区的死亡率（8.15）高于大都市地区（7.72）。中西部地区的AAMR最高（9.18），明尼苏达州的标准偏差为14.08，亚利桑那州的标准偏差为5.44。大多数死亡发生在护理或长期护理机构（52.65%）。结论：死亡率的上升趋势突出了对所有易感人群采取重点预防、诊断和治疗方法的必要性。

Purpose

Sepsis-associated encephalopathy (SAE) is a common neurological complication of sepsis. UMI-77 has shown unique benefits in modulating inflammation to improve sepsis. However, the exact role of UMI-77 in the treatment of SAE and its mechanism are unknown.

Aim

This article analyzes UMI-77 based on metabolomics and explores its mechanism of action in treating SAE based on the brain-gut axis.

Method

In this study, hematoxylin and eosin (H&E) and immunofluorescence staining were used to evaluate the therapeutic effect of UMI-77 on SAE mice. Applying untargeted metabolomics analysis, the metabolic changes in the brain and intestines of septic mice treated with UMI-77 were examined. Furthermore, Receiver Operating Characteristic (ROC) analysis was used to select predictive biomarkers for exploring the mechanism of UMI-77 in treating SAE.

Findings

Sixty-six significant biomarkers in the brain were found and selected with the aid of untargeted the metabolomic method. Metabolic pathway analysis indicates that these differential metabolites are mainly involved in the metabolism of linoleic acid, biosynthesis of phenylalanine, tyrosine, and tryptophan, and phenylalanine metabolism. Seventy-eight important biomarkers were identified and selected in the intestine; metabolic pathway analysis revealed that these differential metabolites were mainly involved in phenylalanine, tyrosine, and tryptophan biosynthesis, and biotin metabolism. L-phenylalanine, L-tyrosine, and 5-hydroxy-tryptophan are the most important metabolites.

Conclusion

UMI-77 plays a positive regulatory role in disrupting the gut microbiota of mice through pathways such as the biosynthesis of phenylalanine, tyrosine, and tryptophan, and can significantly improve neurological function and reduce apoptosis of brain tissue cells.

Background

Vitamins, as a modifiable lifestyle factor, are increasingly recognized for their protective role in cognitive health. However, the synergy or interaction among vitamins remains unclear.

Objectives

This work aimed to analyze the association of serum vitamin D, folic acid (FA), and vitamin B12 with cognitive impairment in the elderly.

Methods

Data included 2582 elderly participants aged 60 and older from the NHANES, 2011–2014. Weighted logistic regression, Bayesian kernel machine regression (BKMR), and weighted quantile sum (WQS) models were used to analyze the association of serum vitamins and their mixture with cognitive disorder risk. Interaction effects among vitamins were investigated. Sensitivity analyses accounting for vitamin supplements, depression, and sleep disorders, and subgroup analyses focusing on high vitamin B12 levels were performed.

Results

After adjusting for confounding factors, serum Vitamin D (OR = 0.695, 95% CI: 0.534–0.905, p = 0.003) and FA (OR = 0.777, 95% CI: 0.604–0.999, p = 0.034) levels were inversely correlated with cognitive disorder risk. Both remained robust after considering vitamin supplements and comorbidities in the sensitivity analyses. The BKMR model indicated a significant increase in cognitive impairment risk when the overall vitamin mixture level fell below the 50th percentile. A U-shaped association was detected between vitamin B12 and cognitive disorder risk. Vitamin B12 and FA had potential interaction effects. The WQS model revealed the largest contribution by FA (56.0%) to the overall protective effect on the cognitive disorder risk. The association with high vitamin B12 was predominantly observed in individuals with specific metabolic conditions, including kidney stones and hypertension.

Conclusion

Optimizing vitamin D and FA levels remains the key to reducing cognitive impairment risk in FA-supplemented populations. Vitamin B12 management requires greater precision; its high level in specific metabolic patients may signal health risks. This study provides new evidence for precise nutritional intervention for the elderly.

背景：维生素作为一种可改变的生活方式因素，在认知健康方面的保护作用日益得到认可。然而，维生素之间的协同作用或相互作用尚不清楚。目的：分析血清维生素D、叶酸（FA）和维生素B12与老年人认知功能障碍的关系。方法：数据纳入2011-2014年NHANES中2582名60岁及以上的老年人。采用加权logistic回归、贝叶斯核机回归（BKMR）和加权分位数和（WQS）模型分析血清维生素及其混合物与认知障碍风险的关系。研究了多种维生素之间的相互作用。对维生素补充剂、抑郁症和睡眠障碍进行敏感性分析，并对高维生素B12水平进行亚组分析。结果：校正混杂因素后，血清维生素D （OR = 0.695, 95% CI: 0.534 ~ 0.905, p = 0.003）和FA （OR = 0.777, 95% CI: 0.604 ~ 0.999, p = 0.034）水平与认知障碍风险呈负相关。在敏感性分析中考虑了维生素补充剂和合并症后，两者都保持稳健。BKMR模型表明，当整体维生素混合物水平低于第50百分位数时，认知障碍风险显著增加。在维生素B12和认知障碍风险之间发现了u型关联。维生素B12和FA有潜在的相互作用。WQS模型显示，FA对认知障碍风险的总体保护作用贡献最大（56.0%）。与高维生素B12的关联主要见于有特定代谢状况的个体，包括肾结石和高血压。结论：优化维生素D和FA水平是降低FA补充人群认知功能障碍风险的关键。维生素B12的管理需要更精确；它在特定代谢患者体内的高水平可能预示着健康风险。本研究为老年人的精准营养干预提供了新的依据。

Objectives:

Electroencephalogram (EEG) microstates can precisely capture transient brain activity changes on sub-second time scales and are used to evaluate global dynamic functional alterations in the brains of Parkinson's disease (PD) patients. This study primarily investigates the differences in microstate features between PD patients and healthy subjects, while exploring their correlations with clinical symptoms.

Methods:

We enrolled 75 PD patients and 44 healthy controls (HCs) who underwent simultaneous EEG microstate recording and Montreal Cognitive Assessment (MoCA) evaluation. All PD patients underwent comprehensive evaluation using the International Movement Disorder Society Unified Parkinson's Disease Rating Scale Parts I and III (MDS-UPDRS I & III).

Results:

PD patients demonstrated significantly increased mean coverage and duration of microstate D compared with HCs, together with elevated transition probabilities from microstates A, B, and C to D. Importantly, both the mean coverage of microstate D and the transition probability from microstate B to D showed significant positive correlations with MDS-UPDRS III scores. Furthermore, receiver operating characteristic (ROC) curve analysis revealed that the mean coverage of microstate D (AUC = 0.674) and the transition probability from microstate B to D (AUC = 0.617) could distinguish between PD patients and HCs.

Conclusion:

The observed abnormalities in microstate dynamics among PD patients may stem from an imbalance in neural network dynamics. These results indicate that EEG microstates may serve as potential biomarkers for assessing and monitoring motor function in PD.

目的：脑电图（EEG）微状态可以精确捕捉亚秒时间尺度上的短暂脑活动变化，并用于评估帕金森病（PD）患者大脑的整体动态功能改变。本研究主要考察PD患者与健康人微观状态特征的差异，并探讨其与临床症状的相关性。方法：选取75例PD患者和44例健康对照（hc），同时进行EEG微状态记录和蒙特利尔认知评估（MoCA）。所有PD患者均采用国际运动障碍学会统一帕金森病评定量表第一部分和第三部分（MDS-UPDRS I & III）进行综合评估。结果：与hc相比，PD患者微状态D的平均覆盖范围和持续时间显著增加，同时从微状态A、B和C到D的过渡概率也增加。重要的是，微状态D的平均覆盖范围和从微状态B到D的过渡概率都与MDS-UPDRS III评分呈显著正相关。此外，受试者工作特征（ROC）曲线分析显示，微状态D的平均覆盖率（AUC = 0.674）和从微状态B到D的转换概率（AUC = 0.617）可以区分PD患者和hc患者。结论：PD患者微状态动力学异常可能是神经网络动力学失衡所致。这些结果表明，脑电图微状态可以作为评估和监测PD运动功能的潜在生物标志物。

Introduction

Insomnia and other sleep disorders are becoming increasingly prevalent worldwide, while current sedative medications such as benzodiazepines, though effective, are often limited by side effects and dependency risks. Therefore, identifying safe natural compounds with sedative potential is of growing scientific and clinical interest. L-quebrachitol (LQL), a naturally occurring cyclitol compound with antioxidant, antimicrobial, and antidiabetic properties, has not been previously evaluated for its sedative effects. The aim of this study is to evaluate the potential sedative effects of LQL through both in vivo and in silico methods.

Methods

In this experiment, 2-day-old broiler chicks (Gallus gallus domesticus) were given thiopental sodium (10 mg/kg, intraperitoneal [ip]) to induce sleep. LQL (1, 5, and 10 mg/kg, ip) and diazepam (2 mg/kg, ip) were administered alone or together to assess their synergistic or antagonistic effects on chicks. To assess its potential for interacting with the GABA_A receptor (α1 and β2 subunits), a molecular docking study was carried out.

Result

According to the in vivo investigation, the results indicate that LQL decreased the latency period while extending the animal's sleep duration time in a dose-dependent manner. Moreover, the combination of LQL-10 (10 mg/kg) and diazepam 2 (2 mg/kg) showed (p < 0.05) enhanced sedative effects significantly by decreasing latency time and prolonging sleeping duration. In addition, LQL has a moderate binding affinity of −5.3 kcal/mol against the GABA_A receptor (α1 and β2 subunits), but forms strong hydrogen bond interactions and similar amino acid residues with standard drug diazepam, suggesting potential therapeutic effects. Further, LQL also demonstrated promising pharmacokinetic properties and low toxicity.

Conclusion

These findings collectively enhance the potential of LQL as an effective sedative therapeutic agent. However, further research, including in vitro studies to confirm the molecular interactions and membrane permeability, followed by well-designed clinical trials, is necessary to fully establish LQL as a safe and effective sedative agent.

失眠和其他睡眠障碍在世界范围内变得越来越普遍，而目前的镇静药物，如苯二氮卓类药物，虽然有效，但往往受到副作用和依赖风险的限制。因此，鉴定具有镇静潜力的安全天然化合物是日益增长的科学和临床兴趣。L-quebrachitol （LQL）是一种天然存在的环糖醇化合物，具有抗氧化、抗菌和抗糖尿病的特性，但其镇静作用尚未被评估。本研究的目的是通过体内和体外两种方法来评估LQL的潜在镇静作用。方法：采用硫喷妥钠（10 mg/kg，腹腔注射）诱导2日龄肉仔鸡（Gallus Gallus domesticus）入睡。LQL（1、5、10 mg/kg, ip）和地西泮（2 mg/kg, ip）分别单独或联合给药，观察其对雏鸡的协同或拮抗作用。为了评估其与GABAA受体（α1和β2亚基）相互作用的潜力，进行了分子对接研究。结果：体内实验结果表明，LQL具有降低小鼠潜伏期，延长小鼠睡眠持续时间的作用，且呈剂量依赖性。此外，LQL-10 （10 mg/kg）与地西泮2 （2 mg/kg）联用后显示p α受体（α1和β2亚基），但与标准药物地西泮形成强氢键相互作用，氨基酸残基相似，提示潜在的治疗作用。此外，LQL还显示出良好的药代动力学特性和低毒性。结论：这些发现共同增强了LQL作为一种有效的镇静治疗剂的潜力。然而，进一步的研究，包括体外研究以确认分子相互作用和膜通透性，以及精心设计的临床试验，需要充分证实LQL是一种安全有效的镇静剂。

Purpose

Depression affects around 280 million people worldwide, and about 30% of patients have treatment-resistant depression. Ketamine has significant scientific evidence supporting its use as an antidepressant, making it a promising approach for treatment-resistant cases. Combining ketamine with psychotherapy may enhance therapeutic response and support longer-lasting cognitive and behavioral change. This pilot proof-of-concept study aims to evaluate the effect of treatment with ketamine infusion combined with psychological intervention in a sample of nine patients with treatment-resistant depression at a general hospital within the Portuguese National Health Service.

Methods

Clinical outcomes were measured through the clinical interview and the patient health questionnaire (PHQ-9) to assess complete or partial improvement.

Results

Following eight weeks of treatment, all showed a reduction in their PHQ-9 scores, with the median score transitioning from a baseline categorization of “severe” depression to a “moderate” level. It was found that 44.4% (4/9) of participants showed a response to treatment (≥ 50% reduction in the PHQ-9 score). Among the patients with suicidal ideation, slightly over half showed remission of these thoughts at the end of treatment. Among the participants subsequently monitored as outpatients, only 29% (2/7) experienced a deterioration in mood within three months post-treatment, requiring an adjustment of antidepressant therapy.

Conclusion

In our study, an improvement in depressive symptoms was observed, despite their severity, in a sample submitted to multiple previous pharmacological strategies.This retrospective study evaluated ketamine infusions combined with psychotherapy in nine patients with treatment-resistant depression at a general hospital. After eight weeks, all participants improved, with PHQ-9 scores shifting from severe to moderate. Overall, 44% responded to treatment, and among those with suicidal ideation, more than half showed remission.

目的：全世界约有2.8亿人患有抑郁症，其中约30%的患者患有难治性抑郁症。氯胺酮有重要的科学证据支持其作为抗抑郁药的使用，使其成为治疗耐药病例的一种有希望的方法。氯胺酮与心理治疗相结合可以增强治疗效果，并支持更持久的认知和行为改变。这项概念验证试验研究的目的是评估氯胺酮输注结合心理干预治疗在葡萄牙国家卫生服务总医院的9例难治性抑郁症患者中的效果。方法：通过临床访谈和患者健康问卷（PHQ-9）测量临床结果，评估完全或部分改善。结果：经过8周的治疗，所有人的PHQ-9得分都有所下降，中位数得分从“严重”抑郁的基线分类转变为“中度”抑郁水平。发现44.4%（4/9）的参与者对治疗有反应（PHQ-9评分降低≥50%）。在有自杀念头的患者中，略多于一半的患者在治疗结束时这些念头得到缓解。在随后作为门诊患者进行监测的参与者中，只有29%（2/7）在治疗后三个月内出现情绪恶化，需要调整抗抑郁治疗。结论：在我们的研究中，观察到抑郁症状的改善，尽管其严重程度，在一个提交了多种先前的药物策略的样本中。本回顾性研究评估了氯胺酮输注联合心理治疗在综合医院治疗的9例难治性抑郁症患者。八周后，所有参与者都有所改善，PHQ-9得分从严重变为中度。总体而言，44%的人对治疗有反应，在有自杀念头的人中，超过一半的人表现出缓解。

Purpose

This study investigated the behavioral and resting-state neural correlates of clinical decision-making among expert gastroenterologists and novice medical students, aiming to understand how diagnostic expertise is reflected in either pre-task and/or post-task brain activity.

Method

Participants completed a clinical decision-making task while behavioral measures (accuracy and response time) were recorded. Resting-state fMRI data were acquired immediately before and following the task. Group differences in brain connectivity were analyzed using seed-based connectivity and multivariate partial least squares (PLS) analyses, focusing on the frontopolar prefrontal cortex (FPPFC) and its associated networks.

Finding

Experts outperformed novices in diagnostic accuracy and speed, especially on “easy” cases, suggesting enhanced cognitive efficiency. Experts also showed more pronounced response time variation with task difficulty, potentially reflecting strategic modulation. Resting-state fMRI revealed that experts had increased post-task connectivity between the FPPFC and the paracingulate gyrus (PaCG), a brain area associated with the executive control network. Novices, by contrast, showed stronger FPPFC connectivity with the posterior cingulate cortex (PCC), part of the default mode network (DMN), indicating a return to internally directed cognition. PLS analyses further revealed that experts engaged executive and attentional network regions post-task, while novices primarily activated DMN regions. Notably, for the expert group only, increased brain activity in attention-related regions was associated with gastroenterologists who had slower, deliberate responses on easy cases.

Conclusion

Clinical expertise is associated with sustained engagement of goal-directed neural networks after task completion, potentially reflecting ongoing cognitive evaluation or preparation. In contrast, novices appear to disengage more readily, reverting to self-referential thought. These findings highlight distinct neural mechanisms that may support the development of diagnostic expertise.

目的：本研究调查了胃肠病学专家和医学生新手临床决策的行为和静息状态神经相关因素，旨在了解诊断专长如何反映在任务前和/或任务后的大脑活动中。方法：参与者完成临床决策任务，同时记录行为测量（准确性和反应时间）。静息状态fMRI数据是在任务之前和之后立即获得的。使用基于种子的连通性和多元偏最小二乘（PLS）分析脑连通性的组差异，重点分析额极前额叶皮层（FPPFC）及其相关网络。发现：专家在诊断准确性和速度上优于新手，特别是在“简单”病例上，这表明他们的认知效率更高。专家们还发现，反应时间随任务难度的变化更为明显，这可能反映了策略调节。静息状态功能磁共振显示，专家们增加了FPPFC和副扣带回（PaCG）之间的任务后连接，PaCG是一个与执行控制网络相关的大脑区域。相比之下，新手的FPPFC与默认模式网络（DMN）的一部分后扣带皮层（PCC）的连通性更强，表明他们回到了内定向认知。PLS分析进一步揭示，专家在任务后参与执行和注意网络区域，而新手主要激活DMN区域。值得注意的是，仅就专家组而言，注意力相关区域的大脑活动增加与胃肠病学家有关，他们对简单病例的反应较慢，深思熟虑。结论：临床专业知识与任务完成后目标导向神经网络的持续参与有关，潜在地反映了正在进行的认知评估或准备。相比之下，新手似乎更容易脱离，回到自我参照思维。这些发现突出了不同的神经机制，可能支持诊断专业知识的发展。
