Association Between SARC-F and Clinical Outcomes in Older Adults With Cardiovascular Diseases Admitted to the Emergency Room: A Longitudinal Study.

Introduction: Sarcopenia can be more significant and severe in the presence of cardiovascular diseases. In hospitalized older adults with acute cardiac disease, assessing strength parameters, muscle mass, and physical performance is difficult largely because of bed rest restrictions. In this context, simple questionnaire to rapidly diagnose sarcopenia (SARC-F) emerges as a feasible screening tool to identify sarcopenia in an emergency room setting.

Immunogenetic Profile Associated with Patients Living with HIV-1 and Epstein-Barr Virus (EBV) in the Brazilian Amazon Region.

Viral coinfection among HIV-positive patients, coupled with the development of AIDS, remains a major public health problem. The synergism between the presence of HIV and other viruses has consequences in relation to changes in the severity of the infection, as well as changes in the natural course of both infections. Several polymorphisms present in genes that encode cytokines have a relevant influence on their transcription and consequently on the production of such immunological molecules.

Sociobehavioral Risk Factors and Clinical Implications of Late Presentation Among People Living with HIV in the Brazilian Amazon Region.

This study aimed to analyze the prevalence, sociobehavioral factors and clinical-laboratory consequences of late presentation among people living with HIV (PLHIV) in the Brazilian Amazon region. In total, 402 HIV + individuals treated at reference units in Belém city (Pará, Brazil) between 2018 and 2019 were evaluated. Late presentation was defined as a first-collection LTCD4 count below 350 cells/µL.

DRB1 locus alleles of HLA class II are associated with modulation of the immune response in different serological profiles of HIV-1/Epstein-Barr virus coinfection in the Brazilian Amazon region.

Background: Epstein-Barr virus (EBV) infection involves distinct clinical and serological profiles. We evaluated the frequency of alleles of locus DRB1 of HLA class II in different serological profiles of EBV infection among HIV-1 infected patients.

Methods: We recruited 19 patients with primary infection, 90 with serological transition and 467 with past infection by EBV, HIV-1 co-infection was 100% in primary infection and approximately 70% in other serological profiles.
