Prevalence of HIV-1 infection and associated characteristics in a Brazilian indigenous population: a cross-sectional study.

Background: Despite significant progress in the areas of prevention, diagnosis, and treatment, HIV continues to result in a substantial number of fatalities on a global scale each year. Gaining insights from epidemiological data can prove instrumental in the development of health promotion strategies, particularly within vulnerable populations, such as indigenous groups. Consequently, our study aimed to investigate the prevalence of HIV infection within the indigenous population residing in the second-largest region of Brazil.

Antimicrobial and antibiofilm activities of desloratadine against multidrug-resistant .

The antimicrobial and antibiofilm activities of the antihistamine desloratadine against multidrug-resistant (MDR) were evaluated. Desloratadine inhibited 90% bacterial growth at a concentration of 64 μg/ml. The combination of desloratadine with meropenem reduced the MIC by twofold in the planktonic state and increased the antibiofilm activity by eightfold.
