Prevalence of SARS-CoV-2 Infection among Children and Adults in 15 US Communities, 2021

During January-August 2021, the Community Prevalence of SARS-CoV-2 Study used time/location sampling to recruit a cross-sectional, population-based cohort to estimate SARS-CoV-2 seroprevalence and nasal swab sample PCR positivity across 15 US communities. Survey-weighted estimates of SARS-CoV-2 infection and vaccine willingness among participants at each site were compared within demographic groups by using linear regression models with inverse variance weighting. Among 22,284 persons >2 months of age and older, median prevalence of infection (prior, active, or both) was 12.9% across sites and similar across age groups. Within each site, average prevalence of infection was 3 percentage points higher for Black than White persons and average vaccine willingness was 10 percentage points lower for Black than White persons and 7 percentage points lower for Black persons than for persons in other racial groups. The higher prevalence of SARS-CoV-2 infection among groups with lower vaccine willingness highlights the disparate effect of COVID-19 and its complications.

Facilitators and barriers to eliciting physical function goals before and after surgery: A qualitative study with clinicians.

OBJECTIVE: Describe clinicians' perspectives of facilitators and barriers to eliciting physical function goals from patients with multiple chronic conditions pre- and post-surgery. METHODS: Semi-structured qualitative interviews were conducted with clinicians, recruited from an academic medical center, who treat adult patients with multiple chronic conditions. Purposive sampling ensured multiple provider types were represented. Interviews were conducted in person or via web conference and were audio recorded. Findings were summarized using descriptive qualitative content analysis. RESULTS: Of the 12 participating clinicians, 92% were female and 83% specialized in geriatrics. Clinicians had a mean of 10.7 (min-max: 1-30) years of experience. Key facilitators to goal-setting conversations were sufficient time, familial support, and patient cognitive ability. Barriers included lack of time, lack of training, patient challenges in choosing realistic and specific actionable goals, emotional barriers, and cognitive challenges. CONCLUSION: Some facilitators and barriers are modifiable, including time, inclusion of family members in the clinical encounter, and clinician training to enable actionable goal setting. These results highlight areas for intervention to facilitate goal elicitation for physical function in clinical care settings. PRACTICE IMPLICATIONS: Clinicians should be aware of the barriers impacting eliciting goals. Healthcare organizations could consider providing effective goal elicitation training and tools to facilitate goal setting conversation.

Sauti ya Vijana (SYV; The Voice of Youth): Longitudinal Outcomes of an Individually Randomized Group Treatment Pilot Trial for Young People Living with HIV in Tanzania.

Sauti ya Vijana is a mental health and life skills intervention delivered by young adult group leaders for the improvement of HIV outcomes in young people living with HIV in Tanzania. This pilot randomized controlled trial estimated exploratory intervention effectiveness compared to standard of care. YPLWH (N = 105) were randomized to receive intervention or SOC. The mean age of participants was 18.1 years and 53% were female. Mean scores on mental health measures (Patient Health Questionnaire [PHQ-9], Strengths and Difficulties Questionnaire [SDQ], UCLA Trauma) were asymptomatic to mild in both study arms through 30-month follow-up with a non-significant fluctuation of 1-2 points. The mean self-reported adherence was higher in the intervention arm across all time points (but the confidence interval contained the null at all time points except 6 months). Risk ratio of virologic suppression (HIV RNA < 400 copies/mL) in the intervention arm compared to SOC was 1.15 [95% CI = 0.95, 1.39]) at 6-months, 1.17 [95% CI: 0.92, 1.48] at 12-months, and 0.99 [95% CI 0.76, 1.31] at 18-months. Though these findings were not powered for statistical significance, the trends in HIV outcomes suggest that SYV holds promise for improving antiretroviral therapy (ART) adherence and virologic suppression in YPLWH.

Sexual and reproductive health needs of young people living with HIV in low- and middle-income countries: a scoping review.

BACKGROUND: Young people living with HIV(YPLWH) in low-and middle-income countries are entering adolescence and young adulthood in significant numbers. The majority of the HIV-related research on these young people has focused on clinical outcomes with less emphasis on their sexual and reproductive health (SRH). There is an increasing awareness of the importance of understanding and addressing their SRH needs, as many are at elevated risk of transmitting HIV to their sexual partners and young women, in particular, are at significant risk for transmitting HIV to their infants. The purpose of this scoping review is to synthesize research investigating the SRH needs of young people living with HIV in low- and middle-income countries. METHODS: We searched electronic databases for studies focusing on young people aged 10-24 years and 27 studies met inclusion criteria. RESULTS: This review identified four themes characterizing research on SRH among young people living with HIV: knowledge of SRH, access to SRH services, sexual practices, and future family planning and childrearing. CONCLUSIONS: Our findings suggest a need for additional research on comprehensive sexuality education to equip YPLWH with knowledge to facilitate desirable SRH outcomes, interventions on sero-status disclosure and condom use, and health provider capacity to provide SRH services in their pre-existing HIV clinical care.

Young people living with HIV(YPLWH) in low-and middle-income countries are entering adolescence and young adulthood in large numbers. The majority of the HIV-related research on these young people has focused on clinical outcomes with less emphasis on their sexual and reproductive health. It is important to understand and address their sexual and reproductive health (SRH) needs, as many are at a high risk of passing on HIV to their sexual partners and young women, in particular, are at significant risk for passing on HIV to their infants. The purpose of this scoping review is to summarize research examining the SRH needs of young people living with HIV in low- and middle-income countries. We searched online databases for studies focusing on young aged 10­24 years and 27 studies were included in the review. This review identified four themes characterizing research on SRH among young people living with HIV: knowledge of SRH, access to SRH services, sexual practices, and future family planning and childrearing. Our findings suggest a need for additional research on comprehensive sexuality education to equip YPLWH with knowledge to facilitate desirable SRH outcomes, interventions on sero-status disclosure and condom use, and health provider capacity to provide SRH services in their pre-existing HIV clinical care.

Perspectives of Chronic Disease Management Among Persons with HIV: A Qualitative Study.

INTRODUCTION: Persons with HIV (PWH) are living to advanced age as a result of ART. These epidemiological changes highlight the importance of innovating chronic care delivery of PWH, but there is limited research regarding patient preferences for chronic care delivery. METHODS: We conducted in-depth interviews of 20 PWH who receive care at the Duke Infectious Diseases Clinic. Manuscript was coded and we used thematic analysis to identify emerging themes from interviewees' responses. RESULTS: Insights of the interviews revealed a strong affinity of PWH with their HIV providers and a reliance on them for primary care as a result. Participants also expressed a strong preference for receiving NCD care from a single provider, regardless of their current chronic disease care configuration. Participants also stated a willingness to embrace new roles of non-provider HIV clinic staff in their chronic disease care. CONCLUSION: Overall, persons living with HIV prefer consolidation and co-location of their care, and are willing to endure minor inconveniences to accommodate this preference. Efforts towards promoting primary care integration into HIV clinics are warranted.

Prevalence and Transmission Dynamics of HIV-1 Transmitted Drug Resistance in a Southeastern Cohort.

BACKGROUND: Transmitted drug resistance (TDR) compromises clinical management and outcomes. Transmitted drug resistance surveillance and identification of growing transmission clusters are needed in the Southeast, the epicenter of the US HIV epidemic. Our study investigated prevalence and transmission dynamics in North Carolina. METHODS: We analyzed surveillance drug resistance mutations (SDRMs) using partial pol sequences from patients presenting to 2 large HIV outpatient clinics from 1997 to 2014. Transmitted drug resistance prevalence was defined as ≥1 SDRMs among antiretroviral therapy (ART)-naïve patients. Binomial regression was used to characterize prevalence by calendar year, drug class, and demographic and clinical factors. We assessed the transmission networks of patients with TDR with maximum likelihood trees and Bayesian methods including background pol sequences (n = 15 246). RESULTS: Among 1658 patients with pretherapy resistance testing, ≥1 SDRMs was identified in 199 patients, with an aggregate TDR prevalence of 12% (95% confidence interval, 10% to 14%) increasing over time (P = .02). Resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs; 8%) was common, followed by nucleoside reverse transcriptase inhibitors (4%) and protease inhibitors (2%). Factors associated with TDR were being a man reporting sex with men, white race, young age, higher CD4 cell count, and being a member of a transmission cluster. Transmitted drug resistance was identified in 106 clusters ranging from 2 to 26 members. Cluster resistance was primarily NNRTI and dominated by ART-naïve patients or those with unknown ART initiation. CONCLUSIONS: Moderate TDR prevalence persists in North Carolina, predominantly driven by NNRTI resistance. Most TDR cases were identified in transmission clusters, signifying multiple local transmission networks and TDR circulation among ART-naïve persons. Transmitted drug resistance surveillance can detect transmission networks and identify patients for enhanced services to promote early treatment.

Mitochondrial calcium and reactive oxygen species regulate agonist-initiated platelet phosphatidylserine exposure.

OBJECTIVE: To study the interactions of cytoplasmic calcium elevation, mitochondrial permeability transition pore (mPTP) formation, and reactive oxygen species formation in the regulation of phosphatidylserine (PS) exposure in platelets. METHODS AND RESULTS: mPTP formation, but not the degree of cytoplasmic calcium elevation, was associated with PS exposure in wild-type, cyclophilin D-null, ionomycin-treated, and reactive oxygen species-treated platelets. In the absence of the mPTP regulator cyclophilin D, agonist-initiated mPTP formation and high-level PS exposure were markedly blunted, but cytoplasmic calcium transients were unchanged. Mitochondrial calcium (Ca(2+)(mit)) transients and reactive oxygen species, key regulators of mPTP formation, were examined in strongly stimulated platelets. Increased reactive oxygen species production occurred in strongly stimulated platelets and was dependent on extracellular calcium entry, but not the presence of cyclophilin D. Ca(2+)(mit) increased significantly in strongly stimulated platelets. Abrogation of Ca(2+)(mit) entry, either by inhibition of the Ca(2+)(mit) uniporter or mitochondrial depolarization, prevented mPTP formation and exposure but not platelet aggregation or granule release. CONCLUSIONS: Sustained cytoplasmic calcium levels are necessary, but not sufficient, for high-level PS exposure in response to agonists. Increased Ca(2+)(mit) levels are a key signal initiating mPTP formation and PS exposure. Blockade of Ca(2+)(mit) entry allows the specific inhibition of platelet procoagulant activity.
