Concurrent training remodels the subcutaneous adipose tissue extracellular matrix of people living with HIV: a non-randomized clinical trial.

Evaluate the effect of 12 wks of concurrent training (CT) in the extracellular matrix (ECM) of subcutaneous adipose tissue (SAT) in people living with HIV/AIDS (PLWHA). In the non-randomized clinical trial, 19 participants, 11 healthy (HIV-) and 18 PLWHA under the use of highly active antiretroviral therapy (HAART) for at least 1 year (HIV+). All participants engaged in a moderate-intensity CT program for 12 weeks, 3 times a week. Before and after CT, aerobic and strength performance were assessed, as well as anthropometric and biochemical blood profiles. In addition, SAT biopsies were performed for histologic and morphometric analyses. Statistical analysis was carried out with R Studio, using descriptive and inferential analysis, ANOVA test, and mixed-effect model (P < 0.05). HIV+ showed higher levels of very-low-density lipoproteins and triglycerides and lower levels of high-density lipoproteins at baseline than HIV- (P < 0.05). All groups showed improved aerobic and strength performances (P < 0.05). Both groups showed reduced adipocyte sizes after CT (P < 0.05). Lastly, HIV+ presented smaller adipocytes and higher elastic fiber deposition at baseline and decreased after training only in HIV+, similar to the HIV group. Thus, CT in PLWHA promoted a decrease in the size heterogeneity of adipocytes and elastic fiber deposition, remodeling the ECM, and improving the SAT fibrosis profile. Brazilian Clinical Trials Registry (ensaiosclinicos.gov.br - UTN: U1111-1214-3022). Novelty: Adipose tissue fibrosis is improved by training in people living with HIV. Concurrent training remodels adipose tissue extracellular matrix.

Raro caso de miíases por Cochliomyia hominivorax (Diptera:Calliphoridae) e Dermatobia hominis (Diptera: Oestridae) em paciente humano / A rare case of myiases by Cochliomyia hominivorax (Diptera: Calliphoridae)and Dermatobia hominis (Diptera: Oestridae) in a human patient

Miíase é uma doença causada por larvas de dípteros que se alimentam de tecidos vivo ou necrosado de hospedeiros. Paciente ingresso em hospital público, em péssimo estado clínico geral, exibia três lesões na cabeça com miíases, das quais foram retiradas 518 larvas de C. hominivorax e duas de D. hominis. Após aretirada de larvas, o paciente foi submetido a enxerto de pele.

Myiasis is a disease caused by an infection due to invasion of tissues or cavities of the body by larvae of dipterans insects that feed on live or necrotic tissue of the hosts. A patient was admitted to a public hospital, with a very bad general clinic state, presenting three lesions in the head, from which 518 larvae of C. hominivorax and two larvae of D. hominis were removed. After the removal of the larvae, the patient was submitted to a skin graft.
