Limited data exist, however, on n-6 and n-3 PUFAs specifically in the context of HIV and pregnancy. Our objective was to assess HIV clinical factors associated with PUFA signatures in pregnant persons with HIV (PWH). In this observational cohort, third trimester plasma PUFA concentrations (six n-6 PUFAs, four n-3 PUFAs) were measured, each as a percent of total fatty acid content, via esterification and gas chromatography in pregnant PWH enrolled from 2009 to 2011 in the Nutrition substudy of the Pediatric HIV/AIDS Cohort Study. PUFA ratios (n-6:n-3) were calculated.

The objective of this study was to estimate the prevalence of PDR and evaluate its impact on viral suppression among patients with HIV receiving care at a large HIV treatment center in Trinidad and Tobago. We retrospectively analyzed data from the Medical Research Foundation of Trinidad and Tobago of patients newly diagnosed with HIV who had HIV genotyping performed. PDR was defined as having at least one drug-resistant mutation. We assessed the impact of PDR on achieving viral suppression within 12 months of ART initiation, using a Cox extended model. Among 99 patients, 31.3% had PDR to any drug, 29.3% to a non-nucleoside reverse transcriptase inhibitor (NNRTI), 3.0% to a nucleoside reverse transcriptase inhibitor, and 3.0% to a protease inhibitor.

In this study, we explored the association between HERV-K expression levels and HMTs development. Clinical data and peripheral blood samples were collected from 236 leukemia, 384 lymphoma patients, and 69 healthy controls. Quantitative polymerase chain reaction was used to detect the expression of HERV-K <i>gag</i>, <i>pol</i>, and <i>env</i> genes in peripheral blood mononuclear cells or different cell subpopulations. Differently expressed HERV-K genes were further tested by using deep sequencing method, and further analyzed with gene ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment. B cell- and T cell-related cytokines in patients were also detected by enzyme-linked immunosorbent assay (ELISA). The results showed that the expression levels of the HERV-K <i>gag</i>, <i>pol</i>, and <i>env</i> genes in patients were significantly higher than in healthy controls. There was a correlation between the expression level of HERV-K and the clinicopathological parameters of leukemia patients. HERV-K expression was increased in the B lymphocytes of leukemia and lymphoma patients, but not in the T cells or neutrophils. The GO and KEGG analyses showed that abnormal expression of the HERV-K locus in patients affected immune regulation. The analysis of cytokines proved that the B cell-related cytokines, including interleukin (IL)-1β, IL-2, IL-4, IL-6, IL-10, tumor necrosis factor (TNF)-α, and interferon-gamma, were significantly decreased in patients, while the T cell-related cytokines, including IL-3, IL-12, and TNF-β, were not significantly changed.
