Unlabelled: Cardiological involvement in HIV infection is relatively rare but it presents important clinical aspects that are still open questions. We report our experience with HIV patients who underwent cardiological evaluation, Doppler echocardiography and follow-up.
Material And Method: We selected 127 patients (9%) on the basis of clinical suspicion of heart disease, taking them from the 1398 admitted for HIV infection between 1992 and 1995. Ninety-six patients had AIDS (group A) and 31 were in pre-AIDS phase (group B). The age was 21-52 years: 83 were males, 44 were females and 91% of the patients had been drug addicts. Echocardiography was executed with Hp Sonos 1000 and Sonos 2500 devices. Follow-up was 6-36 months.
Results: Ninety-two patients (6.5% on total admitted patients) had heart disease. Thirty-five patients were normal on echocardiography. Other diseases were: pericardial effusion in 38 cases (30%), with CD4+ number significantly lower (p < 0.005); dilated cardiomyopathy in 20 patients (16%), with a low CD4+ number (p < 0.005); reversible segmental or diffuse hypokinesia compatible with clinical myocarditis was seen in 11 patients (9%), especially in group A (p < 0.005); infective endocarditis in 17 patients (13%), especially group B (p < 0.005); right ventricular dilatation in 7; discrete right ventricular mass in 3 patients. Sixty-five patients (51%) died during follow-up (group A only). There were 19 cardiac deaths (15%), which represents 1.3% of the total number of patients. Nine of these (47%) were in patients with cardiomyopathy. Total mortality was 85% in patients with dilated cardiomyopathy, 73% in myocarditis cases, 71% in pericarditis cases (especially extracardiac), 66% in right ventricular dilatation cases, 18% in endocarditis cases, 34% in normal cases.
Conclusions: Cardiac complications assume clinical importance, especially in the AIDS phase of HIV infection, but early diagnosis in the pre-AIDS phase is important for treatment. Clinical evaluation and echocardiography are corner-stones of the diagnosis. Prognosis depends especially on the clinical stage of HIV infection and myocardial involvement.

HIV self-sampling and -testing (HIVSS/ST) reduces testing barriers and potentially reaches populations who may not test otherwise. In the Netherlands, at-home HIV tests became commercially available around 2016, but data on user experiences are limited. This study aimed to explore characteristics of users and their experiences with HIVSS/ST.

In Brazil, health policies implemented over the last three decades have enabled rapid testing for HIV to be made available in primary health care services. However, although these policies are national, the implementation of actions is not uniform, as they depend on the local management of local health systems. In this context, the study identified the proportion of women from sexual minorities who had never tested for HIV and the factors associated with access, in a Metropolitan Region of the Brazilian Amazon.

People who use drugs show a higher incidence and prevalence of tuberculosis than people who do not use drugs in areas where Mycobacterium tuberculosis is endemic. However, this population is largely neglected in national tuberculosis programmes. Strategies for active case finding, screening, and linkage to care designed for the general population are not adapted to the needs of people who use drugs, who are stigmatised and difficult to reach.

Objective: Transfusion-transmissible infections (TTIs) are severe threats to blood safety and public health. A retrospective study of blood donor records from 2015 to 2019 in Shiyan, China, was conducted.
Methods: TTI prevalence was analyzed using ELISA, RT-PCR, and demographic data.

Background: HIV rapid diagnostic tests are crucial for timely diagnosis, especially in resource-limited settings. The World Health Organization recommends sensitivity ≥99 % and specificity ≥98 %. This study assessed RDT performance across South Africa's provinces using a proficiency testing program.
