Few information exists on risk factors in patients with neurological disease. Objective: This study was to analyze risk factors for delirium in patients presenting to a neurological emergency department. Methods: This study was observational prospective cohort study. We included all patients with neurological disease, admitted to the emergency department with a stay of more than 8 h, in the period from January to April 2022. The confusion assessment method-intensive care unit delirium detection instrument and DSM-5 criteria were applied to all patients. We obtained information on epidemiological, clinical, and paraclinical variables at the time of admission. Through a univariate and multivariate logistic regression model, we analyzed risk factors for delirium. Results: Of 3661 patients treated in the emergency department, 189 patients were included, 60.8% male gender, age 48 ± 19 years; 44 (23.2%) met criteria for delirium, 81% were diagnosed on admission; delirium scale score/index 12 (interquartile range [IQR] 10-12), and duration of delirium 5 (IQR 2-11) days. Clinical history for risk of delirium: previous delirium (odds ratio [OR] 3.9, 95% CI 2.4-6.1, p = 0.003), stroke (OR 2.2, 95% CI 1.4-3.9, p = 0.009), neurosurgery (OR 2.1, 95% CI 1.2-3.8, p = 0.024), and use of psychoactive drugs (OR 2.5, CI9 5% 1.3-4.6, p = 0.021). The following variables were independent risk factors for delirium through the multivariate logistic regression model:uncontrolled crisis [OR 5.4 (95% CI 1.2-22.9), p = 0.023], supratentorial structural brain lesion [OR 6.1 (95% CI 1.7-21.2), p = 0.004], and neuroinfection OR 9.6 (95% CI 2.9-31.4), p ≤ 0.001]. Conclusions: The frequency of delirium is 23.2% in patients presenting to the neurological emergency department; uncontrolled epilepsy, neuroinfection, and supratentorial brain lesions are independent risk factors for delirium.","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46031180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods : It was a comparative immunohistochemical study to investigate the presence, number, and location of MCs in pilocytic astrocytomas, glioblastoma, medulloblastoma, ependymoma, meningioma, and immature and mature terato-mas. Means, medians, and standard deviation were obtained. Comparation in the number of MCs in the different tumors was carried out using the Mann–Whitney test (p < 0.05). Results: There was a significant difference in the number of MCs between pilocytic astrocytoma ( X ̅ = 0), and mature teratoma ( X ̅ = 65), in relation to the other neoplasms ( X ̅ = 3-11.4). MCs were identified in meningeal lining in meningiomas, in the perivascular space in ependymomas and in the tumor stroma and perivascular space in the rest of the tumors analyzed. Conclusions: MCs appear to play different roles in CNS tumors. Its absence in pilocytic astrocytomas and its presence in glioblastomas suggests a role in the latter, probably related to angiogenesis. The maximum number of MCs was observed in mature teratomas, specifically in relation to stratified squamous epithelium, possibly in relation to trophic factors that contribute to epithelial renewal and maintenance. These findings call for future research to determine if MCs can be a therapeutic target or are important as a prognostic factor.","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46210935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The loss of independence and decreased quality of life are characteristics of these patients that translate into an economic load on relatives and health services. Although myriad factors or metabolic alterations are blamed as causatives, there is a common defect in almost every ND, mitochondrial dysfunction. Mitochondria are the cell’s leading energy supplier; therefore, altering its function will affect the cellular function with the energy demand. Defects in mitochondrial mechanisms such as ATP synthesis by the mitochondrial respiratory chain, mitochondrial dynamics, apoptosis regulation, and oxidative stress are described as part of the pathological characteristics of Alzheimer’s, Parkinson’s, Huntington’s diseases, and Amyotrophic Lateral Sclerosis. In this review, we will briefly describe the mitochondrial roles in cell life before analyzing the recently published bibliography that addresses the mitochondrial dysfunction and mitochondrial mechanisms implicated in ND and will discuss a relevant question in the field: is mitochondrial dysfunction a cause or consequence for these diseases?","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44187586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The restrictive feeling caused by the isolation and the change of life habits that demanded a social separation promoted anxiety, distress, apathy, domestic violence, educational problems, and economic instability, among other aspects. Erroneous statistics, and social media information about the number of people infected by the coronavirus SARS-COV-2, aggravated human anxiety and depression. This review compares the main psychological effects caused by pandemic isolation compared to other isolated social contexts. We studied the primary central nervous system areas involved in human reactive aggressiveness behavior. We examine this behavior in relationship with catecholamines and hormones during social isolation. We do not measure or analyze any hormone in our laboratory and only describe the circuits involved in the neuroendocrine response to the aggressive behavior.
