ABSTRACT
Introduction: Systemic arterial hypertension (SAH) is a significant cause of morbidity and mortality worldwide. Despite the difficulty in diagnosing SAH in the early stages, the rapid detection and management of SAH are essential in preventing the development of target organ injuries. Newer technologies such as metabolomics have been revealed as promising alternatives for SAH diagnoses. Objectives: The purpose of this study is to evaluate, through a systematic review, the metabolomic profile of individuals with and without SAH. Methods: This review followed the PRISMA guidelines on reporting items. It analyses articles selected from the EMBASE and MEDLINE databases that compares metabolites in a hypertensive group with a non-hypertensive group. Results: The differences that reached statistical significance were a higher prevalence of lipids and lactic acid in the hypertensive group, as well as a reduction in methionine. Conclusion: Future research should be conducted to establish a possible clinical implication to this metabolite alteration, by linking it to a potential target organ injury for SAH, such as atherosclerosis, renal failure, retinopathy our ventricular hypertrophy.
Introdução: a hipertensão arterial sistêmica (HAS) é uma causa significativa de morbidade e mortalidade em todo o mundo. Apesar da dificuldade de diagnóstico da HAS em estágios iniciais, a rápida detecção e manejo da HAS são essenciais na prevenção do desenvolvimento de lesões em órgãos-alvo. Tecnologias mais recentes, como a metabolômica, têm se revelado alternativas promissoras para o diagnóstico de HAS. Objetivos: o objetivo deste estudo é avaliar, por meio de uma revisão sistemática, o perfil metabolômico de pacientes com e sem HAS. Método: esta revisão seguiu as diretrizes PRISMA. Foram analisados artigos, selecionados nas bases de dados EMBASE e MEDLINE, que comparavam metabólitos entre um grupo de pacientes hipertensos e um grupo não hipertenso. Resultados: as diferenças dos metabólitos que alcançaram significância estatística foram: a maior prevalência de lipídios e ácido lático no grupo hipertenso, bem como a redução de metionina neste mesmo grupo. Conclusão: novas pesquisas devem ser realizadas para estabelecer qual a implicação clínica desta alteração metabólica, relacionando-a uma potencial lesão de órgão-alvo como a aterosclerose, a insuficiência renal, a retinopatia ou a hipertrofia ventricular.
ABSTRACT
ABSTRACT Objective: To answer questions related to the use of anticoagulants in the treatment of COVID-19 patients. Methods: This was a systematic review and meta-analysis of phase 3 randomized controlled trials comparing the use of anticoagulants in non-hospitalized and hospitalized COVID-19 patients. We searched the following databases: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov from their inception to January 22, 2022. The risk of bias was assessed by the Cochrane risk-of-bias tool, and the quality of evidence was assessed by the Grading of Recommendations Assessment, Development and Evaluation system. Results: A total of 401 studies were initially selected. Of those, 9 met the inclusion criteria and were therefore analyzed (a total of 6,004 patients being analyzed). In non-hospitalized COVID-19 patients, no significant difference was found between post-discharge prophylactic anticoagulation and no intervention regarding venous thromboembolism or bleeding at 30 days. In hospitalized COVID-19 patients, full anticoagulation resulted in a slight reduction in thrombotic events at 30 days (risk difference, −0.03; 95% CI, −0.06 to −0.00; p = 0.04; I2 = 78%), the quality of evidence being moderate. However, no significant difference was found between full anticoagulation and no intervention regarding the risk of major bleeding, the quality of evidence being very low. No significant difference was found between intermediate- and standard-dose prophylactic anticoagulation (risk difference, −0.01; 95% CI, −0.07 to 0.06; p = 0.81; I2 = 0%), the quality of evidence being very low. Conclusions: Therapeutic anticoagulation appears to have no effect on mortality in COVID-19 patients, resulting in a slight reduction in venous thromboembolism in hospitalized patients.
RESUMO Objetivo: Responder a perguntas relacionadas ao uso de anticoagulantes no tratamento de pacientes com COVID-19. Métodos: Revisão sistemática e meta-análise de ensaios clínicos controlados randomizados de fase 3 comparando o uso de anticoagulantes em pacientes com COVID-19 não hospitalizados e hospitalizados. Os bancos de dados MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials e ClinicalTrials.gov foram investigados desde sua criação até 22 de janeiro de 2022. O risco de viés foi avaliado pela ferramenta de risco de viés da Cochrane, e a qualidade das evidências foi avaliada pelo sistema Grading of Recommendations Assessment, Development and Evaluation. Resultados: Inicialmente foram selecionados 401 estudos. Destes, 9 preencheram os critérios de inclusão e, portanto, foram analisados (num total de 6.004 pacientes analisados). Em pacientes com COVID-19 não hospitalizados, não se observou diferença significativa entre anticoagulação profilática pós-alta e nenhuma intervenção no que tange a tromboembolismo venoso ou sangramento em 30 dias. Em pacientes com COVID-19 hospitalizados, a anticoagulação plena resultou em ligeira redução de eventos trombóticos em 30 dias (diferença de risco: −0,03; IC95%: −0,06 a −0,00; p = 0,04; I2 = 78%); a qualidade das evidências foi moderada. No entanto, não se observou diferença significativa entre anticoagulação plena e nenhuma intervenção quanto ao risco de sangramento maior; a qualidade das evidências foi muito baixa. Não se observou diferença significativa entre anticoagulação profilática com dose intermediária e dose-padrão (diferença de risco: −0,01; IC95%: −0,07 a 0,06; p = 0,81; I2 = 0%); a qualidade das evidências foi muito baixa. Conclusões: A anticoagulação terapêutica parece não ter efeito na mortalidade em pacientes com COVID-19, resultando em ligeira redução do tromboembolismo venoso em pacientes hospitalizados.
ABSTRACT
ABSTRACT Objective: Studies in the literature regarding the use of remdesivir to treat COVID-19 patients have shown conflicting results. This study sought to answer questions related to the use of remdesivir for the treatment of patients hospitalized with moderate to severe COVID-19. Methods: This was a systematic review and meta-analysis including phase 3 randomized clinical trials (RCTs) and observational cohort studies selected from various databases, comparing patients hospitalized with moderate to severe COVID-19 receiving remdesivir and controls. Results: A total of 207 studies were retrieved, 9 of which met the eligibility criteria and were included in the study. The meta-analysis using RCTs alone showed no statistically significant differences regarding mortality or use of mechanical ventilation/extracorporeal membrane oxygenation between remdesivir and control groups, and the quality of evidence was moderate and low, respectively. The use of remdesivir increased the recovery rate by 6% (95% CI, 3-9); p = 0.004) and the clinical improvement rate by 7% (95% CI, 1-14); p = 0.02). Additionally, no significant differences in mortality were found between remdesivir and control groups when the meta-analysis used observational cohort studies alone (risk difference = −0.01 (95% CI, −0.02 to 0.01; p = 0.32), the quality of evidence being moderate, and the risk of adverse events was 4% ([95% CI, −0.08 to 0.01]; p = 0.09). Conclusions: The use of remdesivir for the treatment of patients with moderate to severe COVID-19 had no significant impact on clinically important outcomes.
RESUMO Objetivo: Estudos na literatura sobre o uso de remdesivir no tratamento de pacientes com COVID-19 têm apresentado resultados divergentes. O objetivo deste estudo foi responder a perguntas a respeito do uso de remdesivir no tratamento de pacientes hospitalizados com COVID-19 moderada a grave. Métodos: Trata-se de uma revisão sistemática e meta-análise de ensaios clínicos controlados randomizados (ECR) de fase 3 e estudos observacionais de coorte recuperados de diversos bancos de dados, comparando pacientes hospitalizados com COVID-19 moderada a grave recebendo remdesivir a controles. Resultados: Foram recuperados 207 estudos, dos quais 9 preencheram os critérios de elegibilidade e foram incluídos no estudo. A meta-análise somente dos ECR não mostrou diferenças estatisticamente significativas entre os grupos remdesivir e controle quanto à mortalidade ou ao uso de ventilação mecânica/oxigenação por membrana extracorpórea, e a qualidade das evidências foi moderada e baixa, respectivamente. O uso de remdesivir aumentou a taxa de recuperação em 6% (IC95%: 3-9; p = 0,004) e a taxa de melhora clínica em 7% (IC95%: 1-14; p = 0,02). Além disso, não foram observadas diferenças significativas entre os grupos remdesivir e controle quanto à mortalidade quando a meta-análise concentrou-se apenas nos estudos observacionais de coorte [diferença de risco = −0,01 (IC95%: −0,02 a 0,01); p = 0,32; qualidade das evidências: moderada], e o risco de eventos adversos foi de 4% (IC95%: −0,08 a 0,01; p = 0,09). Conclusões: O uso de remdesivir no tratamento de pacientes com COVID-19 moderada a grave não teve impacto significativo em desfechos clinicamente importantes.

ABSTRACT Introduction: Prostate cancer (PC) is the second most commonly diagnosed cancer in males. 68Ga-PSMA PET/CT, a non-invasive diagnostic tool to evaluate PC with prostate-specific membrane antigen (PSMA) expression, has emerged as a more accurate alternative to assess disease staging. We aimed to identify predictors of positive 68Ga-PSMA PET and the accuracy of this technique. Materials and methods: Diagnostic accuracy cross-sectional study with prospective and retrospective approaches. We performed a comprehensive literature search on PubMed, Cochrane Library, and Embase database in search of studies including PC patients submitted to radical prostatectomy or radiotherapy with curative intent and presented biochemical recurrence following ASTRO 1996 criteria. A total of 35 studies involving 3910 patients submitted to 68-Ga-PSMA PET were included and independently assessed by two authors: 8 studies on diagnosis, four on staging, and 23 studies on restaging purposes. The significance level was α=0.05. Results: pooled sensitivity and specificity were 0.90 (0.86-0.93) and 0.90 (0.82-0.96), respectively, for diagnostic purposes; as for staging, pooled sensitivity and specificity were 0.93 (0.86-0.98) and 0.96 (0.92-0.99), respectively. In the restaging scenario, pooled sensitivity and specificity were 0.76 (0.74-0.78) and 0.45 (0.27-0.58), respectively, considering the identification of prostate cancer in each described situation. We also obtained specificity and sensitivity results for PSA subdivisions. Conclusion: 68Ga-PSMA PET provides higher sensitivity and specificity than traditional imaging for prostate cancer.

ABSTRACT Objective: Chloroquine or hydroxychloroquine has demonstrated no effect on the treatment of hospitalized COVID-19 patients. This study aimed to answer questions related to the use of hydroxychloroquine for pre-exposure or post-exposure prophylaxis of SARS-CoV-2 infection and in the treatment of patients with mild COVID-19 in terms of hospitalization, adverse events, and mortality. Methods: This was a systematic review and meta-analysis of phase 3 randomized clinical trials, selected from various databases, which compared patients who received hydroxychloroquine for SARS-CoV-2 prophylaxis or treatment of mild COVID-19 cases with controls. Results: A total number of 1,376 studies were retrieved. Of those, 9 met the eligibility criteria and were included in the study. No statistically significant differences were found between the hydroxychloroquine and control groups in terms of pre- or post-exposure prophylaxis of SARS-CoV-2 infection. The use of hydroxychloroquine increased the risk of adverse events by 12% (95% CI, 6-18%; p < 0.001), and the number needed to harm was 9. In addition, no significant differences were found between the hydroxychloroquine and control groups regarding hospitalization (risk difference [RD] = −0.02; 95% CI, −0.04 to 0.00; p = 0.14) or mortality (RD = 0.00; 95% CI, −0.01 to 0.02; p = 0.98) in the treatment of mild COVID-19. Conclusions: The use of hydroxychloroquine for prophylaxis of SARS-CoV-2 infection or treatment of patients with mild COVID-19 is not recommended.
RESUMO Objetivo: A cloroquina ou hidroxicloroquina não apresentou nenhum efeito no tratamento de pacientes hospitalizados com COVID-19. O objetivo deste estudo foi responder a questões a respeito do uso de hidroxicloroquina na profilaxia da infecção por SARS-CoV-2 pré ou pós-exposição e no tratamento de pacientes com COVID-19 leve no tocante à hospitalização, eventos adversos e mortalidade. Métodos: Trata-se de uma revisão sistemática e meta-análise de ensaios clínicos controlados aleatórios de fase 3 que foram selecionados por meio de buscas em diversos bancos de dados e que compararam controles e pacientes que receberam hidroxicloroquina para profilaxia de SARS-CoV-2 ou tratamento de COVID-19 leve. Resultados: Foram identificados 1.376 estudos. Destes, 9 preencheram os critérios de elegibilidade e foram incluídos no estudo. Não foram encontradas diferenças significativas entre os grupos hidroxicloroquina e controle quanto à profilaxia da infecção por SARS-CoV-2 pré ou pós-exposição. O uso de hidroxicloroquina aumentou o risco de eventos adversos em 12% (IC95%: 6-18%; p < 0,001), e o número necessário para prejudicar foi 9. Não foram encontradas diferenças significativas entre os grupos hidroxicloroquina e controle quanto à hospitalização [diferença de risco (DR) = −0,02; IC95%: −0,04 a 0,00; p = 0,14] e mortalidade (DR = 0,00; IC95%: −0,01 a 0,02; p = 0,98) no tratamento de COVID-19 leve. Conclusões: Não é recomendado o uso de hidroxicloroquina nem na profilaxia da infecção por SARS-CoV-2 nem no tratamento de pacientes com COVID-19 leve.
