Among 582 participants in Western Kenya who were retrospectively tested from January through March 2020, 19 (3.3%) had detectable SARS-CoV-2 antibodies. The prevalence of detectable SARS-CoV-2 antibodies was similar between participants with and without HIV (3.1% vs. 4.0%, p = 0.68). One participant reported a cough in the preceding week but others denied symptoms. These may represent cross-reactivity or asymptomatic infections that predated the first reported COVID-19 cases in Kenya.

This study aimed to identify candidate host epigenetic biomarkers predicting LRA efficacy and HIV-1 rebound kinetics during analytical treatment interruption (ATI).
Retrospective longitudinal epigenetic profiling study from 13 people with HIV (PWH) on virologically suppressive antiretroviral therapy (ART) that participated in a latency-reversal (HDAC inhibitor) clinical trial (NCT01680094) and a subsequent optional ATI to monitor for viral recrudescence after ART cessation.
Genome-wide DNA methylation (DNAm) in purified CD4+ T cells was measured at single-nucleotide resolution using the Infinium MethylationEPIC array. HIV-1 DNA and RNA measures were previously assessed by PCR-based methods and the association of DNAm levels at regulatory sites of the human genome were examined with reservoir size, responsiveness to latency reversal, and time to viral rebound following ATI.
A distinct set of 15 candidate DNAm sites in purified CD4+ T cells at baseline pre-LRA and pre-ATI significantly correlated with t clinical trials.
Nonalcoholic fatty liver disease (NAFLD), insulin resistance, and liver fibrosis are prevalent in individuals co-infected with human immunodeficiency virus type 1 (HIV-1)/hepatitis C virus (HCV), even after HCV eradication. Our aim was to evaluate single nucleotide polymorphisms (SNPs) associated with advanced liver fibrosis in HIV-1/HCV co-infected patients.
In a cohort of 102 participants, we genotyped 16 SNPs in 10 genes previously associated with NAFLD and the innate immune response and correlated the genotypes with liver fibrosis and fat accumulation.
Multinomial logistic regression analysis identified three metabolic parameters that were significantly associated with advanced liver fibrosis (stage F3-4) albumin (odds ratio [OR] 0.80, 95% confidence interval [CI] 0.69-0.91, p = 0.001), percentage of visceral fat area (PVFA) (OR 1.06, 95% CI 1.01-1.12, p = 0.03), and body mass index (BMI) (OR 1.47, 95% CI 1.22-1.77, p < 0.0001). After adjustment for sex, albumin, PVFA, and BMI, we found that three SNPs were significantly associated with advanced fibrosis, one each in PNPLA3/rs738409 (p = 0.016), ADAR-1/rs1127313 (p = 0.029), and IFIH1/rs1990760 (p = 0.033).
Our results indicate that genotyping for these SNPs can be a useful predictive tool for liver fibrosis progression and liver fat accumulation in patients co-infected with HIV-1/HCV.

Although a substantial proportion of ischemic strokes in persons with HIV infection (PWH) is related to large artery disease, studies evaluating elevated cerebrovascular risk in PWH have focused primarily on microvascular disease. We compared the burden of intracranial large artery disease on vessel wall magnetic resonance imaging (VW-MRI) in PWH and HIV-uninfected individuals.
Cross-sectional study.
We recruited antiretroviral therapy-treated PWH with undetectable plasma viral load and HIV-uninfected individuals. All participants were ≥ 40 years of age and at moderate to high cardiovascular risk. We used Poisson and mixed effects logistic regression models to compare the number and associated characteristics of enhancing intracranial arteries on VW-MRI by HIV status.
Of 46 participants (mean age 59 years), 33 were PWH. PWH had nearly four-fold as many enhancing intracranial arteries on VW-MRI than HIV-uninfected individuals (rate ratio 3.94, 95% CI 1.57-9.88, p = 0.003). The majority of wall enhancemn PWH should include evaluation for intracranial large artery disease. VW-MRI provides added value as an adjunct to traditional luminal imaging when evaluating cerebrovascular risk in PWH.
Tenofovir alafenamide (TAF) preferentially loads peripheral blood mononuclear cells (PBMC), resulting in higher PBMC tenofovir-diphosphate (TFV-DP) vs. Polyethylenimine concentration tenofovir disoproxil fumarate (TDF). No studies have yet compared TFV-DP in PBMC from lower than daily dosing between prodrugs, which has potential implications for event-driven pre-exposure prophylaxis and pharmacologic forgiveness.
Two separate randomized, directly observed therapy (DOT) crossover studies (DOT-DBS and TAF-DBS) were conducted to mimic low, medium, and high adherence.
HIV-negative adults were randomized to two 12-week DOT regimens of 33%, 67%, or 100% of daily dosing with emtricitabine (F)/TAF 200 mg/25 mg (TAF-DBS) or F/TDF 200 mg/300 mg (DOT-DBS), separated by a 12-week washout. PBMC steady-state concentrations (Css) of TFV-DP and FTC-TP were estimated using nonlinear mixed models and compared between F/TAF and F/TDF.
Thirty-five participants contributed to 33% (n = 23), 67% (n = 23), and 100% (n = 23) of daily F/TAF regimens. Forty-four contributed to 33% (n = 15), 67% (n = 16), and 100% (n = 32) of daily F/TDF regimens. PBMC TFV-DP Css were 7.3- (95% CI 6.4-8.2), 7.1- (5.9-8.2), and 6.7- (4.4-8.9) fold higher (p < 0.0001) following F/TAF vs. F/TDF; 593 vs. 81.7, 407 vs. 57.4, and 215 vs. 32.3 fmol/106 cells, respectively. TFV-DP was 2.6- (2.1-3.1) fold higher with 33% F/TAF vs. 100% F/TDF. Estimated half-lives (95% CI) of TFV-DP in PBMC were 2.9 (1.5- 5.5) days for F/TAF and 2.1 (1.5-2.9) days for F/TDF. FTC-TP was similar in both studies (p = 0.119).
F/TAF produced 6.7- to 7.3-fold higher TFV-DP in PBMC vs. F/TDF across adherence levels, supporting increased potency and pharmacologic forgiveness with F/TAF in the PBMC compartment.

To investigate HIV- and age- related differences in hip bone structure in men and women.
Cross sectional study of bone structure and HIV serostatus.
We used Quantitative Computed Tomography (QCT) data from the Multicenter AIDS Cohort Study (MACS) and Women's Interagency HIV Study (WIHS) to examine cortical thickness (CT) and cortical (CBMD), trabecular TBMD), and integral (IBMD) bone mineral density across anatomic quadrants of the femoral neck in older adult men who have sex with men (MSM) and women with (PWH) and without (PWOH) HIV infection. The percent difference (%diff) in the means for CT and BMD overall and by quadrant between PWH and PWOH were estimated.
Among 322 MSM (median age 60 years) with bone measures, distributions were similar between HIV serostatus groups with %diff in the quadrant means ranging from -7% to -1% for CT and from -1% to 4% for BMD, and overall lower hip cortical thickness than expected. In contrast, in 113 women (median age 51 years), PWH had lower CT, IBMD and TBMD consistently across all quadrants, with differences ranging from -10 to -20% for CT, -6 to -11% for IBMD and -3 to -6% for TBMD. Estimates reached statistical significance in superoanterior quadrant for CT and IBMD and inferoposterior for CT.
Among women, PWH appear to have a thinner cortex and less dense integral bone compared to PWOH, particularly in the superior quadrants while MSM overall had a thinner than expected hip cortex.

Necrotizing myopathy is a broad term. It includes patients with the recently described immune-mediated necrotizing myopathies (IMNM) who have specific antibodies, such as anti-hydroxy-3-methylglutaryl-CoA reductase or anti-signal recognition particle, seronegative phenotypes that can be associated with cancer, and other types of myositis and connective tissue diseases involving necrotic muscle fibers as a characteristic pathologic feature. Necrotizing myopathies that are not immune-mediated, such as those caused by drugs, dystrophies, infections, or even hypothyroidism are also included. The purpose of this review is to address the differential diagnosis of these disorders.
New IMNM have been described over the last few years, some of them related with checkpoint inhibitors, drugs that are being increasingly used in cancer treatment. Necrotizing myopathy has also been reported in association with specific phenotypes and autoantibodies (e.g. anti-Mi2 dermatomyositis, antisynthetase syndrome, and myositis associated with antimitochondrial antibodies). Rarer cases associated with graft-versus-host disease and severe acute respiratory syndrome coronavirus 2 infection are also emerging.
Differentiation between patients with IMNM and those without the superimposed autoimmune phenomena helps clinicians determine the best individualized approach to use and the appropriate immunosuppressive therapy, whenever needed.

Nursing faculty members may need several mentors to succeed in scholarly productivity, career development, work-life balance, and socialization in the academy. Underrepresented (UR) faculty report additional challenges to success.
The aim of this study was to search the literature for best practices in mentoring UR faculty.
An integrative review was conducted to identify best and evidence-based practices for mentoring UR faculty, including gender, sexual minority, race, ethnicity, and geographic remoteness (rural). Fifteen articles were rated on evidence and methodological quality.
Successful mentorship programs include honest communication, including all stakeholders in forming a mentoring program, goals and activities that come from the mentees, and guaranteed resources.
Underrepresented nursing faculty may benefit from formal mentoring programs, but more research is needed.

The COVID-19 pandemic presented important challenges for the education of nursing students to provide health care with competence, quality, and safety.
The purpose was to analyze knowledge, behavior, and perception of risk regarding COVID-19 and associated factors.
A cross-sectional study was conducted among 2637 Brazilian undergraduate nursing students using a self-reported online survey.
Students' knowledge about COVID-19 in general was considered inadequate. Students had limited knowledge about preventive measures in the hospital environment and recommendations for aerosol precautions. More than 90% of graduates adopted recommended prevention measures, and 86.1% perceived themselves to be at a greater risk of acquired SARS-CoV-2 during clinical practice.
The results show the need to rethink undergraduate nursing education regarding the prevention and control of infectious diseases, including the most appropriate strategies for COVID-19 prevention measures.
