A retrospective survey of non-opportunistic bacterial pathogens isolated from blood cultures of patients with HIV disease has been carried out for a 6-year period, and the antibiotic susceptibility of the 748 microorganisms cultured from 682 consecutive patients, has been evaluated. Gram-positive organisms significantly prevailed over gram-negative ones, with Staphylococcus aureus, coagulase-negative staphylococci, Enterococcus faecalis, Xantomonas maltophilia, Salmonella and Pseudomonas sp. as the most common isolates, and Rhodococcus equi, Serratia, Acinetobacter and Alcaligenes sp. as emerging pathogens. Useful suggestions may be obtained for empiric antimicrobial treatment of suspected sepsis in HIV-infected patients, from the evaluation of the antibiotic susceptibility profile of these non-opportunistic bacterial pathogens.

Exome sequencing reveals a sparse genomic landscape in Kaposi sarcoma.

Kaposi Sarcoma (KS) is a frequently aggressive malignancy caused by Kaposi sarcoma herpesvirus (KSHV/HHV-8). People with immunodeficiencies, including HIV, are at increased risk for developing KS, but our understanding of the contributions of the cellular genome to KS pathogenesis remains limited. To determine if there are cellular genetic alterations in KS that might provide biological or therapeutic insights, we performed whole exome sequencing on 78 KS tumors and matched normal control skin from 59 adults with KS (46 with HIV-associated KS and 13 with HIV-negative KS) receiving treatment at the Uganda Cancer Institute in Kampala, Uganda.

Background: Over the past decade, sexual transmission has become a dominant source of new HIV-1 infection in China. However, very few studies have been conducted to characterize the two sexual transmissions, homosexual and heterosexual transmission. This study was conducted to better understand the relationship between genotypes, drug resistance, and molecular transmission networks in two groups of sexually transmitted HIV-1 in Ningxia, China.

, the bacteria that causes syphilis, is typically acquired through sexual contact but can also be transmitted transplacentally (through the placenta), causing congenital infection. Syphilis in pregnancy is a major contributing factor to perinatal morbidity and mortality. Untreated neonates may develop complications affecting the central nervous system, bones, joints, teeth, eyes, and skin.

Violence experience, interpersonal and community-level, is commonly reported by people living with HIV (PLWH). Understanding the impact of the various forms of violence on HIV outcomes is critical for prioritizing violence screening and support resources in care settings. From February 2021 to December 2022, among 285 PLWH purposively sampled to attain diversity by gender, race/ethnicity, and HIV care retention status in Atlanta, Georgia, we examined interpersonal and community violence experiences and proxy measures of violence (post-traumatic stress disorder (PTSD), anxiety, depression) and their associations with HIV outcomes (engagement and retention in care and HIV viral suppression) using multivariable analysis.

Background: Myanmar is one of the countries in Southeast Asia where serious dengue outbreaks occur and Yangon is among the regions with the highest number of cases in the country. Many infections including dengue are common in Yangon during the rainy season, and co-infections may also occur. Adults are more likely than children to experience co-infections of dengue and other diseases.
