Introduction It is known that viral infections are epidemiologically prevalent and some of them are harmful to the central nervous system (CNS) due to the development of neuropsychiatric syndromes which affect the cognitive, affective, behavioral and perceptual domains. Objective To carry out a comprehensive analysis of the psychiatric and neuropsychiatric repercussions of COVID-19 based on epidemiological, pathophysiological and clinical foundations observed in previous and recent pandemic events, and also to make a proposition about effective therapeutic interventions to help tackle this serious public health problem, more specifically in its neuropsychiatric developments. Method This current literature review has utilized literature reserves and scientific search engines MEDLINE, EMBASE and Web of Science. The search terms included, “SARS-CoV-2”, “etiology,” “psychiatric and neuropsychiatric repercussions”, “severe infections” “COVID-19”. Specific choices of unique papers from each of the searches were identified. The inclusion criteria were relevance and availability of full-text. Papers were excluded on the basis of relevance and non-availability of full-text. Papers were identified in the general literature reserve as pertinent to the search terms. Results The main psychiatric and neuropsychiatric repercussions analyzed were depression, anxiety, post-traumatic stress disorder, psychosis, nonspecific neurological symptoms, delirium, cerebrovascular complications, encephalopathies, neuromuscular disorders, anosmia and ageusia. Conclusion The psychiatric and neuropsychiatric symptoms of acute respiratory syndromes can appear during or after the infectious stage. Among the risk factors pointed out for such effects are the female gender, health professionals, presence of avascular necrosis and distressing pain.

A pandemia da COVID-19 trouxe consigo desafios para além da propagação do vírus, haja vista o ascendente negacionismo e obscurantismo com que o maior desafio de saúde pública dos últimos tempos foi tratado por uma parcela da sociedade. Métodos: Os estudos foram identificados em jornais e revistas de grande porte e circulação internacional. Resultados: A sociedade tem sido exposta à desinformação científica, a qual resulta em uma profunda vulnerabilidade social com graves danos à saúde pública. Por outro lado, os médicos se mantêm aquém do desejado no que se refere ao conhecimento técnico/científico. A capacidade de análise crítica e aplicação de forma

Despite causing high morbidity, IgG4-related disease (IgG4-RD) and its gastroenterological manifestations lack better and greater theoretical contributions. Therefore, the objective of this work was to evaluate the clinical–epidemiological, diagnostic and treatment aspects of the gastrointestinal manifestations of this disease. A systematic review was carried out using the PubMed, Scopus and Embase databases between January 2012 and March 2023 with the following descriptors: “Immunoglobulin G4-Related Disease” (MeSH) AND #2 “Gastrointestinal Tract” (MeSH). Our data collection grouped a total of 3607 patients from mostly epidemiological cohort studies and cross-sectional follow-ups. In the subgroup analysis, IgG4-RD was associated with male gender, with an estimated prevalence between 54% and 80%. In our findings, the prevalence by topography was presented in the following ranges: lacrimal glands (17–57%); salivary glands (28–72%); pancreas (19–60%); biliary tract (5–40%); retroperitoneal cavity (9–43%). Longitudinal studies are needed to better map the natural history of the gastrointestinal manifestations of IgG4-RD and enable the formulation of individualized treatments.
