Previous studies investigated the impact of weight-related abuse (WRA) on eating pathology. However, the circumstances of such an effect are still unclear. Our study aimed to examine the relationship between verbal WRA and binge eating (BE) behavior via attentional bias (AB) to threat cues and difficulties in emotion regulation.
Method
We conducted a parallel mediation model. On the basis of the purposive sampling method, 183 individuals with obesity and overweight (70.5% female and 28.4% male; Meanage = 32.78), from February to June 2019, were recruited from a nutrition clinic in Tehran. The participants completed the BE scale (BES), the weight-related abuse questionnaire (WRAQ), the difficulties in emotion regulation scale (DERS), and the dot probe task (DPT).
Results
AB to threat cues had a significantly negative association with verbal WRA and BE. Difficulties in emotion regulation showed a significant positive association with verbal WRA and BE. The parallel mediation model showed a direct effect of verbal WRA on BE. Moreover, the bootstrap analysis revealed that difficulties in emotion regulation could mediate the association between verbal WRA and BE.
Conclusions
Our findings suggest that experiences of verbal WRA can contribute to cognitive bias to negative emotion, maladaptive emotion regulation strategies, and behavioral problems like BE.
导言：以往的研究调查了体重相关虐待（WRA）对饮食病理学的影响。然而，这种影响的具体情况仍不清楚。我们的研究旨在通过对威胁线索的注意偏差（AB）和情绪调节的困难，探讨口头 WRA 与暴食行为之间的关系：我们建立了一个平行中介模型。根据目的性抽样方法，我们于 2019 年 2 月至 6 月在德黑兰的一家营养诊所招募了 183 名肥胖和超重患者（女性占 70.5%，男性占 28.4%；平均年龄 = 32.78）。参与者完成了BE量表（BES）、体重相关虐待问卷（WRAQ）、情绪调节困难量表（DERS）和点探测任务（DPT）：结果：威胁线索 AB 与口头 WRA 和 BE 呈显著负相关。情绪调节困难与口头 WRA 和 BE 呈显著正相关。平行中介模型显示，口头 WRA 对 BE 有直接影响。此外，自引导分析表明，情绪调节方面的困难可以调节言语性 WRA 与 BE 之间的关联：我们的研究结果表明，言语 WRA 的经历会导致对负面情绪的认知偏差、不适应的情绪调节策略以及 BE 等行为问题。

Background
Observational studies have suggested that obsessive–compulsive disorder (OCD) may be associated with Alzheimer's disease (AD). However, whether OCD is a causal risk factor for AD remains unclear. This study aimed to assess the causal effect of OCD on AD risk by performing a two-sample Mendelian randomization (MR) analysis.
Methods
Genome-wide association summary statistics were obtained for OCD, comprising 2688 cases and 7037 controls, as well as for AD, including 21,982 cases and 41,944 controls from Kunkle et al.’s study, and 39,918 cases and 358,140 controls from Wightman et al.’s study. On the basis of two diverse thresholds, OCD-associated genetic variants were screened as instrumental variables (IVs) for subsequent MR analyses. Inverse variance weighed was the primary MR method. MR-Egger, weighted median, and weighted mode were used as supplementary MR methods. Various sensitivity tests assessed the reliability of MR results.
Results
On the basis of strict IV selecting thresholds, inverse-variance weighted (IVW) identified significant causal associations between genetic liability to OCD and increased risk of AD in two different sources ((i) Kunkle et al.: odds ratio [OR] = 1.070, 95% confidence interval [CI]: 1.015–1.127, p = 0.012; (ii) Wightman et al. 0.012; (iii) Wightman et al.: OR = 1.051, 95% CI: 1.014–1.090, p = 0.007). Three other supplementary MR methods yielded similar results to IVWs (OR > 1). Furthermore, all results were replicated in MR analyses based on lenient IV selecting thresholds. The sensitivity tests indicated that MR results were stable and not affected by significant horizontal pleiotropy.
Conclusions
This comprehensive MR study suggests that genetic liability to OCD is a causal risk factor for AD. Early intervention in patients with OCD may be beneficial in preventing future AD progression.
背景：观察性研究表明，强迫症（OCD）可能与阿尔茨海默病（AD）有关。然而，强迫症是否是阿尔茨海默病的因果风险因素仍不清楚。本研究旨在通过进行双样本孟德尔随机化（MR）分析，评估强迫症对阿尔茨海默病风险的因果效应：获得了强迫症（包括 2688 例病例和 7037 例对照）和 AD 的全基因组关联汇总统计数据，包括 Kunkle 等人研究中的 21,982 例病例和 41,944 例对照，以及 Wightman 等人研究中的 39,918 例病例和 358,140 例对照。根据两种不同的阈值，强迫症相关遗传变异被筛选为工具变量（IV），用于后续的 MR 分析。反方差权衡是主要的 MR 方法。MR-Egger、加权中位数和加权模式被用作辅助MR方法。各种敏感性测试评估了 MR 结果的可靠性：在严格的 IV 选择阈值的基础上，反方差加权法（IVW）在两个不同的来源中发现了强迫症遗传责任与 AD 风险增加之间的显著因果关系（(i) Kunkle 等人：几率比 [OR] = 1.070，95% 置信区间 [CI]：1.015-1.127, p = 0.012；(ii) Wightman et al：OR = 1.051，95% CI：1.014-1.090，p = 0.007）。其他三种辅助 MR 方法的结果与 IVWs 相似（OR > 1）。此外，所有结果都在基于宽松的 IV 选择阈值的 MR 分析中得到了重复。敏感性测试表明，MR 结果稳定，不受显著水平多效性的影响：这项全面的磁共振研究表明，强迫症的遗传易感性是导致注意力缺失症的一个因果风险因素。对强迫症患者进行早期干预可能有利于预防未来的注意力缺失症进展。

Background
We aimed to identify different Guillain–Barré syndrome (GBS) subtypes, demyelination, axonal degeneration, and reversible conduction failure (RCF) as early as possible by analyzing the initial clinical and electrophysiological examinations.
Methods
This study retrospectively collected GBS patients between October 2018 and December 2022 at Beijing Tiantan Hospital. The diagnostic criteria for the initial electrophysiological study were based on Rajabally's criteria, and the criteria for the serial electrophysiological study were based on Uncini's criteria. All subjects underwent clinical and electrophysiological evaluations at least twice within 8 weeks.
Results
A total of 47 eligible patients with GBS were included, comprising 19 acute inflammatory demyelinating polyradiculoneuropathy (AIDP), 18 axonal degenerations, and 10 RCFs. In the RCF group, 40%, 30%, and 30% patients were diagnosed as AIDP, axonal, and equivocal at the initial study, respectively. The AIDP group had significantly higher cerebrospinal fluid (CSF) protein than the RCF (123.8 [106.4, 215.1] mg/dL vs. 67.1 [36.8, 85.6] mg/dL, p = 0.002) and axonal degeneration (123.8 [106.4, 215.1] mg/dL vs. 60.8 [34.8, 113.0] mg/dL, p < 0.001) groups. The RCF group had significantly lower Hughes functional grades at admission (3 [2, 4] vs. 4 [4, 4], p = 0.012) and discharge (1.0 [1.0, 2.0] vs. 3.0 [2.0, 3.0], p < 0.001) than the axonal degeneration group and showed significantly shorter distal motor latency (DML), Fmin, Fmean, Fmax, and lower F% than the AIDP group (p < 0.05).
Discussion
The early identification of RCF from AIDP had relatively obvious features, including slightly elevated CSF protein levels and normal or slightly prolonged DML and F-wave latencies, contrasting with the apparent elevation and prolongation seen in AIDP. Differentiating RCF from axonal degeneration remains challenging. One potential distinguishing factor is that the motor function in RCF tends to be better than in the latter.

The vagal sensory nerve (VSN) is an essential interoceptive pathway that is connected to every level of the body. Its intricate genetic coding provides sustenance for physiological processes, including controlling blood pressure and respiration. Electroacupuncture (EA) is a proven surface stimulation therapy that can regulate vagal nerve activity, which can effectively prevent cardiovascular diseases. A growing number of studies have concentrated on the mapping of VSN codes, but little is known, and the physiological background of how EA influences interoceptive has not been fully explored.
Method
Here, we incorporate the hypothesized interaction among EA targets, VSNs, and the heart. This offers suggestions for using a versatile and focused EA strategy to modify vagal interoceptive awareness to enhance cardiovascular conditions. We first clarified the major role of vagal nerve in the control of cardiac activity. Additionally, we clarified the multidimensional coding pattern in the VSNs, revealing that the targeted control of multimodal interoceptive is the functional basis of the synchronization of cardiovascular system.
Finding
We propose a strategy in which EA of the VSNs is employed to activate the interoceptive loop and reduce the risk of cardiovascular disease.
目的：迷走感觉神经（VSN）是一条重要的感知间通路，连接着身体的各个层面。其复杂的基因编码为包括控制血压和呼吸在内的生理过程提供了营养。电针（EA）是一种行之有效的表面刺激疗法，可以调节迷走神经的活动，从而有效预防心血管疾病。越来越多的研究集中在迷走神经编码的映射上，但对其知之甚少，而 EA 如何影响互感的生理背景也未得到充分探讨：在此，我们将假定的 EA 目标、VSN 和心脏之间的相互作用结合起来。方法：在此，我们将假定的 EA 目标、迷走神经网络和心脏之间的相互作用结合起来，从而为使用多用途、有针对性的 EA 策略提供建议，以改变迷走神经的内感知意识，从而改善心血管状况。我们首先阐明了迷走神经在控制心脏活动中的主要作用。此外，我们还阐明了迷走神经的多维编码模式，揭示了多模态互感的定向控制是心血管系统同步的功能基础：我们提出了一种策略，即利用 VSNs 的 EA 激活互感环路并降低心血管疾病风险。

Epidemiological studies revealed an unestablished association between neuroticism and posttraumatic stress disorder (PTSD) and we conducted mendelian randomization (MR) analyses to examine whether neuroticism clusters of worry, depressed affect, and sensitivity to environmental stress and adversity (SESA) were involved in the development of PTSD.
Method
We obtained data on three neuroticism clusters, PTSD, and nine other psychiatric disorders from genome-wide association studies summary statistics and employed univariable, multivariable, and mediation MR analyses to explore causal associations among them.
Results
Neuroticism clusters were linked with PTSD (depressed affect (odds ratio [OR]: 2.94 [95% confidence interval: 2.21–3.92]); SESA (2.69 [1.95–3.71]; worry (1.81 [1.37–2.99])). Neuroticism clusters were also associated with psychiatric disorders, with the depressed effect on panic disorder (PD) (2.60 [1.14–5.91]), SESA on anorexia nervosa (AN) (2.77 [1.95–3.94]) and schizophrenia (2.55 [1.99–3.25]), worry on major depressive disorder (MDD) (2.58 [2.19–3.05]). In multivariable MR, only the SESA-PTSD association remained (2.60 [2.096, 3.107]) while worry-PTSD and depressed affect-PTSD associations attenuated to nonsignificance. Mediation MR analyses suggested that PD mediated 3.76% of the effect of depressed effect on PTSD and AN mediated 10.33% of the effect of SESA on PTSD.
Conclusion
Delving deeper into neuroticism clusters, we comprehensively understand the role of neuroticism in PTSD.

The monocyte–lymphocyte ratio (MLR) is a hematological test parameter that reflects the status of both monocytes and lymphocytes as inflammatory cells. This study aims to investigate the relationship between MLR and carotid intraplaque neovascularization (IPN) in patients with asymptomatic carotid stenosis.
Methods
We performed the Angio Planewave Ultrasensitive (AngioPLUS) screening for patients with carotid plaques. The carotid plaque stability was evaluated by semiquantitative visual grading of carotid IPN. Binary logistic regression models were performed to determine the associations between different clinical and laboratory indicators and the presence of high IPN.
Results
A total of 160 patients were eventually enrolled with 99 in the low IPN group (Scores 0–1) and 61 in the high IPN group (Score 2). Univariate logistic regression showed that age, monocytes, lymphocytes, glycated hemoglobin (HbA1c), fibrinogen, d-dimmer, and MLR were significantly associated with the presence of high IPN (all p < 0.05). Multivariate logistic regression models showed that MLR was significantly associated with the presence of high IPN after adjusting for other covariates. An MLR value of 32.9 was the optimal cutoff value to differentiate high and low IPN. High MLR was also significantly correlated with the presence of high IPN (odds ratio [OR] = 4.08, 95% confidence interval [CI]: 1.69–9.88, p = 0.002) when included in the above multivariate logistic regression model.
Conclusion
Elevated MLR is closely associated with the presence of high IPN and may serve as a surrogate biomarker for carotid IPN.

We aimed to investigate the relationship between systemic immune-inflammation index (SII) and short-term mortality in acute ischemic stroke (AIS) with internal carotid artery (ICA) severe stenosis and stroke associated pneumonia (SAP) patients.
Methods
Information on general demographic, laboratory data, CT angiography, magnetic resonance angiography, or digital subtraction angiography were obtained. The predictive power was evaluated by assessing the area under the receiver operating characteristic (ROC) curve. The logistic regression was performed to assess the association of SII and short-term mortality in severe stenosis ICA-AIS and SAP patients.
Result
Among 342 patients with severe stenosis ICA-AIS and SAP, death occurred in 66 patients during 120 days follow-up. Multivariate regression analyses indicated that increased SII predicts higher mortality in 120 days follow-up, and the risk of short-term mortality in SII > 666.31 × 109/L group is increased 4.671-fold. Patients with SII > 666.31 × 109/L had higher proportion of male, hypertension, smoking, higher admission NIHSS score, higher systolic blood pressure, and higher proportion of 120 days mortality. Higher SII predicted a worse 120 days mortality was worked out by Kaplan–Meier methods.
Conclusion
An elevated SII was remarkably associated with 120 days mortality in severe stenosis ICA-AIS and SAP patients.

Post-traumatic stress disorder (PTSD) is a debilitating psychological disorder that occurs after exposure to catastrophic-level experiences. Although alterations in immune function have been identified in individuals with PTSD, the causal relationship between the two remains unclear.
Methods
To investigate the causal relationship between PTSD and immune function, we conducted the forward and backward two-sample Mendelian randomization (MR) analyses, based on summary-level genome-wide association studies (GWAS) data on PTSD and immune cell traits.
Results
For the forward MR analysis, PTSD was found to reduce the levels of CD62L− dendritic cell (DC) (beta = −0.254, FDR = 0.01), CD86+ myeloid DC (beta = −0.238, FDR = 0.014), CD62L− myeloid DC (beta = −0.26, FDR = 0.01), CD62L− CD86+ myeloid DC absolute count (beta = −0.264, FDR = 0.024), and CD62L− CD86+ myeloid DC (beta = −0.328, FDR = 0.002). In contrast, PTSD was observed to increase the level of CD28− CD8dim T-cell absolute count (beta = 0.27, FDR = 0.029). For the backward MR analysis, the odds ratio (OR) for CD33 on CD33dim HLA DR+ CD11b− in relation to PTSD risk was found to be 1.045 (95% CI = 1.021–1.069, FDR = 0.008). The OR for FSC-A on HLA DR+ CD8br was 1.048 (95% CI = 1.018–1.079, FDR = 0.039) and for CCR2 on CD14− CD16+ monocyte was 1.059 (95% CI = 1.027–1.092, FDR = 0.008). No significant pleiotropy was detected in both forward and backward MR analyses.
Conclusion
The bidirectional MR study shed light on the intricate interplay between immune function and PTSD. The identification of a bidirectional causal relationship between T cells and PTSD opens new avenues for considering innovative approaches to the prevention and early intervention of PTSD.
