A cross-sectional study was carried out on medical students from a private Peruvian university. The aim was to describe knowledge and attitudes towards COVID-19 as well as the student’s perception of the role of media outlets and social media. Of the students, 32% did not know that during the first five days of illness, serological tests are preferred for diagnosing COVID-19 over molecular tests; 73% reported being willing to work as a volunteer during the pandemic, and 94% received false information regarding COVID-19 on social media. This study demonstrated that information regarding diagnostic tests should be reinforced and that the high percentage of students willing to volunteer during the COVID-19 pandemic should not be overlooked Se realizó un estudio transversal e estudiantes de Medicina de una universidad privada de Lima. El objetivo fue describir el nivel de conocimientos y las actitudes sobre la COVID-19, además de su percep-ción sobre el rol de los medios de comunicación y de las redes sociales. El 32% no sabía que en los prime-ros cinco días de la enfermedad, las pruebas serológicas son preferibles para diagnosticar la COVID-19, comparadas con las pruebas moleculares; el 73% reportó estar dispuesto a trabajar como voluntario durante la pandemia y el 94% recibió información falsa sobre la COVID-19 en las redes sociales. Este estudio demuestra que la información sobre el uso de pruebas diagnósticas debe ser reforzada y que se debe tomar en cuenta el alto porcentaje de estudiantes dispuestos a ser voluntarios durante la pandemia de la COVID-19.

BACKGROUND HIV-infected persons in resource-limited settings may experience high rates of antiretroviral therapy (ART) change, particularly because of toxicity or other nonfailure reasons. Few reports address patient outcomes after these modifications. METHODS HIV-infected adults from the 7 Caribbean, Central and South America network clinical cohorts who modified >1 drug from the first ART regimen (ART-1) for any reason thereby starting a second regimen (ART-2) were included. We assessed cumulative incidence of, and factors associated with, death, virologic failure (VF), and regimen change after starting ART-2. RESULTS Five thousand five hundred sixty-five ART-naive highly active ART initiators started ART-2 after a median of 9.8 months on ART-1; 39% changed to ART-2 because of toxicity and 11% because of failure. Median follow-up after starting ART-2 was 2.9 years; 45% subsequently modified ART-2. Cumulative incidences of death at 1, 3, and 5 years after starting ART-2 were 5.1%, 8.4%, and 10.5%, respectively. In adjusted analyses, death was associated with older age, clinical AIDS, lower CD4 at ART-2 start, earlier calendar year, and starting ART-2 because of toxicity (adjusted hazard ratio = 1.5 vs. failure, 95% confidence interval: 1.0 to 2.1). Cumulative incidences of VF after 1, 3, and 5 years were 9%, 19%, and 25%. In adjusted analyses, VF was associated with younger age, earlier calendar year, lower CD4 at the start of ART-2, and starting ART-2 because of failure (adjusted hazard ratio = 2.1 vs. toxicity, 95% confidence interval: 1.5 to 2.8). CONCLUSIONS Among patients modifying the first ART regimen, risks of subsequent modifications, mortality, and virologic failure were high. Access to improved antiretrovirals in the region is needed to improve initial treatment success.

BACKGROUND: Strongyloidiasis is a gut infection with Strongyloides stercoralis which is common world wide. Chronic infection usually causes a skin rash, vomiting, diarrhoea or constipation, and respiratory problems, and it can be fatal in people with immune deficiency. It may be treated with ivermectin or albendazole or thiabendazole. OBJECTIVES: To assess the effects of ivermectin versus benzimidazoles (albendazole and thiabendazole) for treating chronic strongyloides infection. SEARCH METHODS: We searched the Cochrane Infectious Diseases Group Specialized Register (24 August 2015); the Cochrane Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library; MEDLINE (January 1966 to August 2015); EMBASE (January 1980 to August 2015); LILACS (August 2015); and reference lists of articles. We also searched the metaRegister of Controlled Trials (mRCT) using 'strongyloid*' as a search term, reference lists, and conference abstracts. SELECTION CRITERIA: Randomized controlled trials of ivermectin versus albendazole or thiabendazole for treating chronic strongyloides infection. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed risk of bias in the included trials. We used risk ratios (RRs) with 95% confidence intervals (CIs) and fixed- or random-effects models. We pooled adverse event data if the trials were sufficiently similar in their adverse event definitions. MAIN RESULTS: We included seven trials, enrolling 1147 participants, conducted between 1994 and 2011 in different locations (Africa, Southeast Asia, America and Europe).In trials comparing ivermectin with albendazole, parasitological cure was higher with ivermectin (RR 1.79, 95% CI 1.55 to 2.08; 478 participants, four trials, moderate quality evidence). There were no statistically significant differences in adverse events (RR 0.80, 95% CI 0.59 to 1.09; 518 participants, four trials, low quality evidence).In trials comparing ivermectin with thiabendazole, there was little or no difference in parasitological cure (RR 1.07, 95% CI 0.96 to 1.20; 467 participants, three trials, low quality evidence). However, adverse events were less common with ivermectin (RR 0.31, 95% CI 0.20 to 0.50; 507 participants; three trials, moderate quality evidence).In trials comparing different dosages of ivermectin, taking a second dose of 200 mug/kg of ivermectin was not associated with higher cure in a small subgroup of participants (RR 1.02, 95% CI 0.94 to 1.11; 94 participants, two trials).Dizziness, nausea, and disorientation were commonly reported in all drug groups. There were no reports of serious adverse events or death. AUTHORS' CONCLUSIONS: Ivermectin results in more people cured than albendazole, and is at least as well tolerated. In trials of ivermectin with thiabendazole, parasitological cure is similar but there are more adverse events with thiabendazole.

Objetivos: Describir las características clínico-epidemiológicas y la mortalidad de pacientes hospitalizados con tuberculosis (TBC) en el Departamento de Enfermedades Infecciosas, Tropicales y Dermatológicas del Hospital Nacional Cayetano Heredia (DEITD-HNCH) de Lima, Perú. Material y Métodos: Estudio retrospectivo y observacional que incluyó a pacientes hospitalizados desde enero de 1990 hasta diciembre de 2000 con diagnóstico de TBC definitiva o probable. Resultados: Se registraron 1340 altas con diagnóstico de TBC (18.7 %). La edad promedio de los pacientes hospitalizados con TBC fue 33.5 ± 15.1 años, 69.2% fueron varones y 28.1 % tuvieron infección por el Virus de la Inmunodeficiencia Humana (VIH). La mortalidad por TBC fue 17.2 % y permaneció constante durante el período. El número de muertes por TBC (230 pacientes) representó el 37.5 % de las muertes por todas las causas (613 pacientes). De los fallecidos por TBC, 151 (65.6 %) tuvieron TBC multisistémica, 60 (26.1 %) TBC pulmonar y 19 (8.3 %) TBC extrapulmonar exclusiva. Hubo sospecha clínica de TBC multidrogorresistente (TBC-MDR) en 51 (22.2 %) pacientes fallecidos. Edad mayor de 30 años (OR=1.6, 1.2
