The study included patients aged ≥60 years who had dementia, hearing loss, and neurological diseases. Those with Parkinson's disease and secondary epilepsy were excluded. Data was analyzed for its demographics, clinical features, predisposing factors, treatment, dementia duration and progression, and hearing loss outcomes. All statistical analyses were performed using IBM's SPSS software, version 29.0.0. Statistical significance was established at a p-value of ≤0.05 and a confidence interval of 95%.Results: The findings indicated that 88.8% of the 143 patients exhibited dementia, with Alzheimer's disease being the most prevalent type. Moreover, 18.2% had hearing issues, and 11.2% had other complaints. Audiometry was performed in 15.4% of the cases. Hearing loss was present in 14.7% of the patients, being primarily bilateral, ranging from mild to severe.Conclusion: This study has clarified the link between hearing loss and dementia onset and has emphasized the need for early evaluation and intervention for individuals with hearing impairment.","PeriodicalId":19284,"journal":{"name":"Neurosciences","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11460783/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142392111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Median NCSs were performed on the participants in three different standing positions with the elbow as the stimulation point: 1) with the arm adducted (P1), 2) with the arm anteflexed (P2), and 3) with the arm raised upwards (P3). We obtained median nerve compound muscle action potential (CMAP) latency, duration, peak-to-peak (PP) amplitude, onset-to-negative peak (OP) amplitude, negative area/duration. Three CMAPs were obtained in each position, and the mean and minimum/maximum values at each position were analyzed.Results: The mean age (minimum-maximum) of the participants (11 male, 9 female) was 28.5±6.5 (20-42) years. Median nerve CMAP means (median) of latency/negative duration in the P1, P2, and P3 positions were 6.82±0.59 (6.83)/5.50±0.76 (5.39) ms, 6.99±0.56 (7.02)/5.72±0.73 (5.73) ms, and 7.03±0.58 (7.12)/5.79±0.80 (5.83) ms.

Sprague-Dawley rats were subjected to middle cerebral artery occlusion (MCAO) for 1.5 h, and treated with ATRA at 2 and 24 h after reperfusion. Neurological deficit scores on behavioral tests, and cerebral infarct volume, microglial polarization, and the expression levels of inflammatory cytokines and proteins associated with TLR4/NF-κB signaling were assessed.Results: The ATRA administration reduced cerebral infarct volume and ameliorated neurological deficit scores in MCAO rats. Additionally, ATRA relieved cerebral edema and downregulated the secretion of proinflammatory cytokines after stroke. Finally, ATRA attenuated the polarization of the microglia toward the M1 phenotype and promoted the activation of the beneficial M2 phenotype; the underlying mechanism potentially involved the suppression of the TLR4/NF-κB signaling pathway.Conclusion: The ATRA treatment promoted functional recovery in an experimental model of ischemic stroke by attenuating neural inflammation. ATRA potentially modulated microglia-mediated neuroinflammation via the downregulation of the TLR4/NF-κB signaling pathway, which makes it a candidate treatment for post-stroke neuroinflammation.","PeriodicalId":19284,"journal":{"name":"Neurosciences","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11460776/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142392124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A self-administered questionnaire was given among participants using social media platforms. The questionnaire included socio-demographic characteristics, weight-loss-related characteristics, General Anxiety Disorder (GAD-7) to measure anxiety, and Patient Health Questionnaire (PHQ-9) to measure depression experienced by the patients.Results: Of the 721 patients, 73.9% were females, and 30.1% were aged between 30 to 39 years old. The prevalence of patients who underwent weight loss by surgery and injection was 47.7% and 41.2%, respectively. Overall, symptoms of anxiety and depression were detected in 19.7% and 24%, respectively. Independent risk factor of anxiety and depression was the symptom of the psychiatric disorder prior to surgery, while the independent protective factor for anxiety and depression was older age. Depression was higher in weight loss injection users.Conclusion: Nearly one-quarter of the study population experienced anxiety or depression following weight loss treatment. Weight loss treatment by injections increases the risk of depression. However, improved self-confidence, mood, and relationships with family and friends were some of the positive changes exhibited by the patients after undergoing weight loss treatment. Appropriate psychiatric evaluation is necessary before and after weight loss intervention.","PeriodicalId":19284,"journal":{"name":"Neurosciences","volume":null,"pages":null},"PeriodicalIF":1.2,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11460780/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142392142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
