Major depressive disorder (MDD) affects people all over the world, and yet, its etiology is complex and remains incompletely understood. In this review, we aim to assess recent advances in understanding depression and its regulation, as well as its interaction with circadian rhythms. Circadian rhythms are internalized representations of the periodic daily light and dark cycles. Accumulating evidence has shown that MDD and the related mental disorders are associated with disrupted circadian rhythms. In particular, depression has often been linked to abnormalities in circadian rhythms because dysregulation of the circadian system increases susceptibility to MDD. The fact that several rhythms are disrupted in depressed patients suggests that these disruptions are not restricted to any one rhythm but rather involve the molecular circadian clock core machinery. The sleep-wake cycle is one rhythm that is often disrupted in depression, which often leads to disturbances in other rhythms. The circadian disruptions manifested in depressed patients and the effectiveness and fast action of chronobiologically based treatments highlight the circadian system as a key therapeutic target in the treatment of depression. This review assesses the evidence on rising depression rates and examines their contributing factors, including circadian misalignment. We discuss key hypotheses underlying depression pathogenesis, potential etiology, and relevant animal models, and underscore potential mechanisms driving depression's growing burden and how understanding these factors is critical for improving prevention and treatment strategies.

To evaluate the therapeutic effect of a modified Devine procedure with a subcutaneous sliding fixation method for the treatment of congenital concealed penis, we retrospectively selected 45 patients with congenital concealed penises who were admitted to General Hospital of Ningxia Medical University (Yinchuan, China) between September 2020 and November 2023. In all cases, the penis was observed to be short, and retracting the skin at the base revealed a normal penile body, which immediately returned to its original position upon release. All patients underwent the modified Devine procedure with subcutaneous sliding fixation and completed a 12-week postoperative follow-up. A statistically significant increase in penile length was observed postoperatively, with the median length increasing from 4.0 (interquartile range [IQR]: 3.5-4.8; 95% confidence interval [CI]: 3.9-4.4) cm to 8.0 (IQR: 7.8-8.0; 95% CI: 7.7-7.9) cm, with P < 0.001. The parents were satisfied with the outcomes, including increased penile length, improved hygiene, and enhanced esthetics. Except for mild foreskin edema in all cases, no complications (such as infections, skin necrosis, or penile retraction) were observed. The edema was resolved within 4 weeks after the operation. This study demonstrates that the modified Devine procedure utilizing the subcutaneous sliding fixation method yields excellent outcomes with minimal postoperative complications, reduced penile retraction, and high satisfaction rates among patients and their families.

BACKGROUND: Difficulty in chewing has been shown to be associated with increased mortality, geriatric syndromes, and poor activities of daily living, indicating the need for intervention. Chewing difficulties are related to tooth loss, periodontitis, dry mouth, and a number of oral health conditions. Diabetes mellitus (DM) is one of the major causes of global burden of diseases, and has been associated with poor oral health. Prospective association between oral health status and the development of diabetes has also been reported. However, relationship between glycemic control and self-reported chewing difficulty remains less explored in working-age populations. The objective of this study is to cross-sectionally explore the association between fasting blood glucose (FBG) and self-reported chewing difficulty in adults working in a Japanese worksite. METHODS: Participants from the Aichi Workers' Cohort Study who responded to the 2018 survey were included. Participants were categorized into five FBG groups (<100, 100-109, 110-125, 126-159, and ≥160 mg/dl). Multivariable odds ratios (ORs) and 95% confidence intervals (CIs) for chewing difficulty were estimated using logistic regression adjusted for age, sex, body mass index, smoking and alcohol consumption status, number of teeth, presence of periodontal disease and the number of anti-diabetic medication classes. RESULTS: A total of 164 participants (4.2%) reported difficulty with chewing, the prevalence of which tended to increase with increasing FBG level. FBG ≥160 mg/dl was significantly and strongly associated with difficulty with chewing in the final multivariable model (multivariable OR 3.84 [95% CI 1.13-13.0]). CONCLUSIONS A relationship between higher FBG levels and difficulty with chewing was observed, independent of potential confounding factors. However, prospective or interventional studies are needed to determine causality.

Objective: This study aims at spotlighting different lines of management of aggressive vertebral hemangioma (VH) through a retrospective analysis of single center experience. Methods: Patients diagnosed with aggressive VHs in a tertiary referral center were reviewed from 2014 through 2024. Data of patients who met the inclusion criteria were analyzed. Patients of all ages, both sexes, and all varieties of clinical presentation were included, only patients who underwent at least one intervention were included. Results: The study included nine patients, comprising six females and three males, with a mean age of 29.3 years (ranging from 14 to 46). Six patients underwent Trans-arterial embolization (TAE), of whom five underwent further surgical procedures, while one patient found TAE to be sufficient as a stand-alone management technique. Eight patients underwent surgical management, five of whom were pre-operatively embolized. Conclusions Aggressive VHs are rare, and their management is challenging. Most cases require a multi-modal management, especially when presented with neurological deficit. Pre-operative embolization and/or vertebroplasty are safe and useful tools to decrease intra-operative bleeding of such a vascular pathology in cases undergoing open surgical procedures.

This study aims to determine the level of origin, branching pattern and exits of the iliohypogastric and ilioinguinal nerves in relation to the psoas major muscle. Additionally, this study confirms the presence and retroperitoneal courses of the double nerves. We dissected a total of 24 iliohypogastric and ilioinguinal nerves (6 male and 6 female cadavers). The origin, branching, and exits in relation to the psoas major muscle, the absence of these nerves or the presence of double nerves, and their retroperitoneal course were carefully examined. All the images were recorded by photographing. In this study, we mainly observed variations in exits, branching patterns, and their retroperitoneal course. The iliohypogastric nerve was absent in 2 cases (8.3%). In the type I pattern, in 1 case (4.2%), the common trunk descends anteriorly to the iliac vessels from the iliolumbar vessels. In 4 cases (16.7%), the double ilioinguinal nerve with different branch patterns and retroperitoneal courses was observed. In 1 single nerve case (4.2%), the ilioinguinal nerve descends anterior to the iliac vessels from the iliolumbar vessels. To our knowledge, the branching pattern of the double ilioinguinal nerves and their retroperitoneal course have not been reported in any available data. Sound knowledge of the variations in the origin, branches, and retroperitoneal course of the iliohypogastric and ilioinguinal nerves is very helpful for the improvement of peripheral nerve blocks and other various surgical procedures to avoid complications and nerve injuries.

Purpose: Gastrin-releasing peptide receptor (GRPR), a member of the bombesin G-protein-coupled receptor family, is introduced as the promising target for the diagnosis and therapy of various tumors. This study aimed to develop a novel diagnostic agent of [ 113mIn]In-AMBA for single photon emission computed tomography (SPECT) imaging of GRPR expressing tumors. Methods: 113mIn was provided from an in-house made 113Sn/ 113mIn generator in the chloride form. [ 113mIn]In-AMBA wasprepared in the optimal conditions and the stability was checked in PBS buffer and human serum, Then the binding affinityand internalization of the radiolabeled compound were investigated in PC3 cell lines at 120 min. the biodistribution of the radiolabeled peptide was studied in normal rats. Results: [ 113mIn]In-AMBA was prepared with radiochemical purity (RCP) > 98% under the optimal labeling conditions. Thecompound indicated significant stability in PBS buffer and human serum (> 95% at 180 min post preparation). High binding affinity (51% at 60 min) and internalization (64% at 120 min) of the radiolabeled compound towards PC3 cell lines were alsoobserved. The major accumulation of the compound was seen in kidneys, and other GRPR-expressing tissues. Conclusion The biodistribution of the labeled compound in normal rats indicated rapid elimination of the complex from the blood, and considerable accumulation in the GRPR-expressing organ of pancreas, in complete agreement with similar labeled compounds. [ 113mIn]In-AMBA can be a suitable candidate for SPECT imaging of GRPR-expressed tumors.

Objectives: The objectives of this review and meta-analysis were twofold: first, to determine theprevalence of substance use among school-going children in Arab and African countries; andsecond, to highlight the considerable influence of variables such as the nation’s region and thetimeframe of the study on the prevalence of substance use. Methods: Research was sourced from Science Direct, Scopus, Web of Science, Google Scholar,and PubMed. Thirty-seven articles were incorporated in accordance with the PRISMA guidelines. This review included studies published from 2013 to 2023. The statistical meta-analysis was performed using Comprehensive Meta-Analysis ver. 3 software. Across 37 studies, the total number of study participants was 73,508. Results: The meta-analysis revealed that tobacco was the most commonly used substance, with a prevalence of 16% (95% confidence interval [CI], 12.7%–20.02%). This was closely followed by alcohol, which had a prevalence of 15% (95% CI, 10.5%–22.8%), stimulants at 11.4% (95% CI, 7.4%– 17%), khat at 10% (95% CI, 5.7%–15%), and cannabis at 8% (95% CI, 3.3%–18.4%). Notably, alcohol was the only substance that showed an increasing trend in prevalence from before to after 2019, rising from 13.3% (95% CI, 6.2%–26.1%) to 17% (95% CI, 10.2%–27%) (p < 0.001). Additionally, the prevalence of substance use varied significantly between Arab and African countries (p < 0.001). Conclusion Although the prevalence of substance use among school-going populations hassignificantly decreased over time, with the exception of alcohol, it is imperative that bothAfrican and Arab countries implement comprehensive measures and stringent laws to addressthe production and marketing of substances.
