RESUMEN

PURPOSE: COVID-19 continues to be an urgent World issue. Receptors of angiotensin converting enzyme 2 (ACE2), gateway of SARS-CoV-2, are present in the lungs, bladder, prostate, and testicles. Therefore, these organs face high risk of damage caused by the virus and this mechanism may explain non-respiratory symptoms of the disease. MATERIALS AND METHODS: This systematic review, guided by the PRIMSA statement, was proposed to elucidate possible urological complications of COVID-19. Searches were carried out in Medline (PubMed), Cochrane (CENTRAL), Embase, MedRxiv and LILACS. Bias analysis was made using the specific Newcastle-Ottawa Scale for each study design. RESULTS: Search was carried out until April 2022, and 8,477 articles were identified. Forty-nine of them were included in this systematic review. There is evidence that lower urinary tract symptoms and acute scrotum may be signs of COVID-19 in men, although in a small proportion. Also, the disease may have a transitory impact on male fertility, evidenced by several alterations in sperm counts. However, it must be clarified whether this impact is transitory, or may last for longer periods. Several patients showed reduction of total value of testosterone. Two authors linked low levels of testosterone with worse outcomes of COVID-19, suggesting that the hormone may be used as an early biomarker of the severity of the disease. Moreover, it is extremely unlikely that SARS-CoV-2 is transmitted by semen. CONCLUSION: This systematic review identified possible repercussions of COVID-19 in the urinary as well as in the male reproductive system.

RESUMEN

Serologic testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) promises to assist in assessing exposure to and confirming the diagnosis of coronavirus disease 2019 (COVID-19), and to provide a roadmap for reopening countries worldwide. Considering this, a proper understanding of serologic-based diagnostic testing characteristics is critical. The aim of this study was to perform a structured systematic review and meta-analysis to evaluate the diagnostic characteristics of serological-based COVID-19 testing. Electronic searches were performed using Medline (PubMed), EMBASE, and Cochrane Library. Full-text observational studies that reported IgG or IgM diagnostic yield and used nucleic acid amplification tests (NAATs) of respiratory tract specimens, as a the reference standard in English language were included. A bivariate model was used to compute pooled sensitivity, specificity, positive/negative likelihood ratio (LR), diagnostic odds ratio (OR), and summary receiver operating characteristic curve (SROC) with corresponding 95% confidence intervals (CIs). Five studies (n=1,166 individual tests) met inclusion criteria. The pooled sensitivity, specificity, and diagnostic accuracy for IgG was 81% [(95% CI, 61-92);I2=95.28], 97% [(95% CI, 78-100);I2=97.80], and 93% (95% CI, 91-95), respectively. The sensitivity, specificity, and accuracy for IgM antibodies was 80% [(95% CI, 57-92);I2=94.63], 96% [(95% CI, 81-99);I2=92.96] and 95% (95% CI, 92-96). This meta-analysis demonstrates suboptimal sensitivity and specificity of serologic-based diagnostic testing for SARS-CoV-2 and suggests that antibody testing alone, in its current form, is unlikely to be an adequate solution to the difficulties posed by COVID-19 and in guiding future policy decisions regarding social distancing and reopening of the economy worldwide.

RESUMEN

INTRODUCTION: As COVID-19 develops around the world, numerous publications have described the psychiatric consequences of this pandemic. Although clinicians and healthcare systems are mainly focused on managing critically ill patients in an attempt to limit the number of casualties, psychiatric disease burden is increasing significantly. In this scenario, increased domestic violence and substance abuse have been recently reported. OBJECTIVE: The objective of this study is to perform a systematic review of the literature regarding the consequences of severe acute respiratory syndrome-CoV-2 infection in terms of domestic violence and substance abuse, and compare incidences found. MATERIALS AND METHODS: We conducted a literature search using the preferred reporting items for systematic reviews and meta-analyses guidelines. The keywords included "domestic violence," "substance abuse" AND "COVID-19," including multiple variants from December 2019 through June 2020. An extensive bibliographic search was carried out in different medical databases: Pubmed, EMBASE, LILACS, medRxiv, and bioRxiv. Titles and abstracts were reviewed according to the eligibility criteria. The risk of bias in the retrieved articles was assessed by the Joanna Briggs Institute's critical assessment instrument. RESULTS: A total of 1505 papers were initially retrieved after consulting the selected databases. After browsing through titles and abstracts, 94 articles were initially included considering the predefined eligibility criteria. After a more detailed analysis, only six scientific articles remained in our selection. Of these, three were evaluating domestic violence against children, while the other three were about substance abuse. CONCLUSION: There is not enough evidence to support the concept that COVID-19 has led to an increase in the rates of domestic violence and substance abuse. The initial decrease in violence reports might not translate into a real reduction in incidence but in accessibility. Apparently, there has been a slight increase in alcohol and tobacco abuse, especially by regular users, which also requires confirmatory studies. The inconsistency between expert opinon articles and the actual published data could be a result of the limited time since the beginnging of the crisis, the fact that psychitaric patients have been chronically exposed to stressful situatons, and a possible stimulated increase in demand for psychatric consultations.
