A elaboração das Diretrizes para Diagnóstico e Tratamento da COVID-19 é uma resposta rápida ao enfrentamento da COVID-19, diante da declaração de pandemia pela Organização Mundial de Saúde (OMS) e das iniciativas do Ministério da Saúde para enfrentamento dessa nova situação no Brasil. ...
A intensa produção de evidência sobre o assunto nos últimos meses faz destas Diretrizes um documento dinâmico que terá versões provisórias e atualizações periódicas, acompanhando a produção de novas evidências para assim estabelecer recomendações.

6 July 2021. The “WHO consolidated guidelines on tuberculosis. Module 3: Diagnosis - Rapid diagnostics for tuberculosis detection 2021 update” is the latest document replacing the one issued in 2020. Three new nucleic acid amplification test (NAAT) classes are endorsed by WHO and included in the... latest consolidated guideline

The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

Guidelines for diagnosis, acute care and post-COVID-19 follow-up for children and adolescents
Tuberculosis (TB) is the deadliest infectious disease in most low- and middle-income countries, claiming more than 4,000 lives each day. The unprecedented COVID-19 pandemic has seriously impacted people with pre-existing health conditions. People with TB are usually more vulnerable to other infectio...ns, including the novel coronavirus, due to pre-existing lung damage. They are also at higher risk of developing complications from COVID-19.

Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

.Chronic manifestations of Chagas disease present as disabling and life-threatening condi-tions affecting mainly the cardiovascular and gastrointestinal systems. Although meaningful research has outlined the different molecular mech...anisms underlying Trypanosoma cruzi’s infection and the host-parasite interactions that follow, prompt diagnosis and treatment remain a challenge, particu-larly in developing countries and also in those where the disease is considered non-endemic. This review intends to present an up-to-date review of the parasite’s life cycle, genetic diversity, virulence factors, and infective mechanisms, as well as the epidemiology, clinical presentation, diagnosis, and treatment options of the main chronic complications of Chagas disease.
