Social support is a critical component of achieving positive health outcomes for youth living with HIV (YLWH). Mobile health (mHealth) has significant potential for providing social support to YLWH. However, little is known about the domains of social support most needed by YLWH which mHealth interventions might address. Drawing on the spontaneous creation of WhatsApp support groups by YLWH in Nairobi, Kenya, we characterized Kenyan YLWH's social support needs and potential roles of social media groups in meeting them. We conducted interviews and focus-groups with 68 YLWH, 24 caregivers and 20 healthcare workers, and observed two YLWH-led WhatsApp groups for 6 weeks. Youth reported that existing support systems, including family and healthcare workers, already provided informational and instrumental support. However, they emphasized unmet companionship and emotional support needs, leading to isolation, hopelessness, and medication adherence challenges. Participants identified connection with other YLWH as a unique source of emotional and companionship support that allowed them to feel more secure and less isolated. Interviews and observed WhatsApp chats demonstrated that WhatsApp groups were a desirable medium for companionship support that overcame barriers to in-person connection.

Exposure to low to moderate arsenic (As) levels has been associated with type 2 diabetes (T2D) and other chronic diseases in American Indian communities. Prenatal exposure to As may also increase the risk for T2D in adulthood, and maternal As has been associated with adult offspring metabolic health measurements. We hypothesized that T2D-related outcomes in adult offspring born to women exposed to low to moderate As can be evaluated utilizing a maternally-derived molecular biosignature of As exposure. Herein, we evaluated the association of maternal DNA methylation with incident T2D and insulin resistance (Homeostatic model assessment of insulin resistance [HOMA2-IR]) in adult offspring. For DNA methylation, we used 20 differentially methylated cytosine-guanine dinucleotides (CpG) previously associated with the sum of inorganic and methylated As species (ΣAs) in urine in the Strong Heart Study (SHS). Of these 20 CpGs, we found six CpGs nominally associated (p < 0.05) with HOMA2-IR in a fully adjusted model that included clinically relevant covariates and offspring adiposity measurements; a similar model that adjusted instead for maternal adiposity measurements found three CpGs nominally associated with HOMA2-IR, two of which overlapped the offspring adiposity model. After adjusting for multiple comparisons, cg03036214 remained associated with HOMA2-IR (q < 0.10) in the offspring adiposity model. The odds ratio of incident T2D increased with an increase in maternal DNA methylation at one HOMA2-IR associated CpG in the model adjusting for offspring adiposity, cg12116137, whereas adjusting for maternal adiposity had a minimal effect on the association. Our data suggests offspring adiposity, rather than maternal adiposity, potentially influences the effects of maternal DNAm signatures on offspring metabolic health parameters. Here, we have presented evidence supporting a role for epigenetic biosignatures of maternal As exposure as a potential biomarker for evaluating risk of T2D-related outcomes in offspring later in life.

BACKGROUND/UNASSIGNED:Interventions targeting combined sexual and reproductive health, Human Immunodeficiency Virus (HIV) management and mental health care in sub-Saharan Africa (SSA) are few. There is a need to address common determinants of poor mental, psychosocial and sexual and reproductive health and rights (SRHR) through multimodal and multipronged interventions for adolescents. The main objective of this study was to identify whether and how interventions targeting adolescent SRHR and HIV with a focus on pregnant and parenting adolescents in SSA include mental health components and how these components and their outcomes have been reported in the literature. METHODS/UNASSIGNED:We carried out a two process scoping review approach between 01.04.2021 and 23.08.2022. In the first stage, we searched the PubMed database to identify studies focusing on adolescents and young people aged 10 to 24 from 2001 to 2021. We identified studies focusing on HIV and SRHR that had mental health and psychosocial aspects to the interventions. Our search yielded 7025 studies. Of these 38 were eligible based on our screening criteria that covered interventions, and on further scrutiny, using PracticeWise, an established coding system, we identified select problems and practices to provide a more granular assessment of how interventions developed for this context mapped on to specific problems. At this second stage process, we selected 27 studies for inclusion as actual interventional designs for further systematic scoping of their findings and we used the Joanna Briggs Quality Appraisal checklist to rate these studies. This review was registered within the International Prospective Register of Systematic Reviews (PROSPERO), number CRD42021234627. FINDINGS/UNASSIGNED:Our first set of findings is that when coding problems and solutions, mental health concerns were the least common category of problems targeted in these SRHR/HIV interventions; nevertheless, psychoeducation and cognitive behavioral strategies such as improved communication, assertiveness training, and informational support were offered widely. Of the 27 interventional studies included in the final review, 17 RCTs, 7 open trials, and 3 mixed designs, represented nine countries of the 46 countries in SSA. Intervention types included peer, community, family, digital, and mixed modality interventions. Eight interventions focused on caregivers and youth. Social or community ecology associated problems (being an orphan, sexual abuse, homelessness, negative cultural norms) were the most common risk factors and were more frequent than medical issues associated with HIV exposure. Our findings highlight the relevance and centrality of social issues related to adolescent mental and physical health along with the need to strengthen multimodal interventions along the lines of problems we have identified in our review. INTERPRETATION/UNASSIGNED:Combined interventions jointly addressing adolescent SRHR, HIV, and mental health have been relatively understudied, despite evidence that adverse social and community factors are rampant in this population. FUNDING/UNASSIGNED:MK was funded by Fogarty International CenterK43 TW010716-05 and lead the initiative.

BACKGROUND:The prevalence of sleep disturbances among prostate cancer (PCa) survivors, and extent of urologist involvement in sleep care are not well-studied. METHODS:PCa survivors (n = 167) and urologists (n = 145) were surveyed about sleep disturbances and survivorship care practices. RESULTS:Most PCa survivors had sleep disturbances, including 50.9% with poor sleep quality, 18.0% with clinical/severe insomnia, and 36.5% at high-risk for sleep apnea. Few urologists routinely screened for sleep disturbances, as recommended in national cancer survivorship guidelines. CONCLUSIONS:Optimal PCa survivorship care should incorporate screening for sleep disturbances, addressing comorbid factors affecting sleep and referring to sleep medicine when appropriate.

BACKGROUND:Self-measured blood pressure monitoring (SMBP) is essential to effective management of hypertension. This study aims to evaluate effectiveness and implementation of SMBP that leverages: cellular-enabled home BP monitors without a need for Wi-Fi or Bluetooth; simple communication modalities such as text messaging to support patient engagement; and integration into existing team-based workflows in safety-net clinics. METHODS:This study will be conducted with patients in San Francisco who are treated within a network of safety-net clinics. English and Spanish-speaking patients with diagnosed hypertension will be eligible for the trial if they have recent BP readings ≥140/90 mmHg and do not have co-morbid conditions that make home BP monitoring more complex to manage. This study will implement a three-arm randomized controlled trial to compare varying levels of implementation support: 1) cellular-enabled BP monitors (with minimal implementation support), 2) cellular-enabled BP monitors with protocol-based implementation support (text reminders for patients; aggregated BP summaries sent to primary care providers), and 3) cellular-enabled BP monitors and pharmacist-led support (pharmacist coaching and independent medication adjustments). RESULTS:For the main analysis, we will use mixed effects linear regression to compare the change in primary outcome of systolic BP. Secondary outcomes include BP control (<140/90 mmHg), medication intensification, patient-reported outcomes, and implementation processes (i.e., engagement with the intervention). DISCUSSION:This study will design and test a digital health intervention for use in marginalized populations treated within safety net settings, evaluating both effectiveness and implementation to advance more equitable health outcomes.

BACKGROUND:Social media use in medicine has exploded, with uptake by most physicians and patients. There is a risk of dissemination of inaccurate information about urological conditions on social media. Physicians, as key opinion leaders, must play a role in sharing evidence-based information through social media. OBJECTIVE:To identify and describe the top 100 urology influencers on the Twitter social media platform and to correlate Twitter influence with academic impact in urology. DESIGN, SETTING, AND PARTICIPANTS/METHODS:Twitter influence scores for the search topic "urology" were collected in April 2022 using published methodology. The top 100 personal accounts with the highest computed scores were linked to individuals' names, all-time h index, geographic location, specialty, attributed sex, and board certification status in this cross-sectional study. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS/METHODS:We examined the correlation between influence rank and h index. RESULTS AND LIMITATIONS/CONCLUSIONS:Of the top 100 Twitter influencers on the topic of urology, the majority are from the USA (64%), male (85%), and practicing urologists (91%). Some 93% of US urology influencers are board-certified. Only 22 of the 50 US states are represented. The second most frequent country is the UK, with ten urology influencers. The median all-time h index is 42 (interquartile range 28.25-58). There is a weak positive correlation between influence rank and h index (r = 0.23; p = 0.02). Limitations of the study include the inability to validate the accuracy of the proprietary ranking algorithm and investigation of just one social media platform. CONCLUSIONS:The top Twitter influencers in urology are mostly board-certified US urologists. Collectively, influencers have a relatively greater academic impact in comparison to the average urologist, although there is a weak positive correlation between Twitter influence and h index among top Twitter influencers. PATIENT SUMMARY/RESULTS:Given the explosion of medical information on Twitter, we report the personal accounts with the greatest impact for the topic of "urology". We found that most urology influencers on Twitter are US board-certified urologists with a strong research history.

BACKGROUND:STRIVE was a prospective, 4-year, multicenter, observational, open-label, single-arm study of natalizumab treatment in anti-JC virus antibody-negative patients with early relapsing-remitting multiple sclerosis (RRMS). OBJECTIVE:Study objectives examined the effects of natalizumab on cognitive processing speed, confirmed disability improvement (CDI), and patient-reported outcomes (PROs). METHODS:Clinical and PRO secondary endpoints were assessed annually over 4 years in STRIVE. The Symbol Digit Modalities Test (SDMT) was used as a measure of cognitive processing speed. PROs were assessed using the Multiple Sclerosis Impact Score (MSIS-29) and the Work Productivity and Activity Impairment Questionnaire (WPAI). RESULTS:At all four annual assessments, the proportion of patients in the intent-to-treat (ITT) population (N = 222) who exhibited clinically meaningful improvement in their SDMT score from baseline (i.e., change ≥ 4 points) ranged from 41.9 to 54.0%. The cumulative probability of CDI at 4 years in patients in the ITT population with a baseline Expanded Disability Status Scale score ≥ 2 (N = 133) was 43.9%. Statistically significant reductions in the mean change from screening in the MSIS-29 physical and psychological scores, indicating improved quality of life, were observed over all 4 years (P ≤ 0.0012 for all). A statistically significant decrease from screening in the impact of MS on regular activities, signifying an improvement in this WPAI measure, was also observed over all 4 years of the study. CONCLUSION/CONCLUSIONS:These results further extend our knowledge of the effectiveness, specifically regarding improvements in cognitive processing speed, disability and PROs, of long-term natalizumab treatment in early RRMS patients. CLINICALTRIALS/RESULTS:GOV: NCT01485003 (5 December 2011).

OBJECTIVE/UNASSIGNED:Personalizing preventive therapies for atherosclerotic cardiovascular disease (ASCVD) is particularly important for older adults, as they tend to have multiple chronic conditions, increased risk for medication adverse effects, and may have heterogenous preferences when weighing health outcomes. However, little is known about outcome preferences related to ASCVD preventive therapies in older adults. METHODS/UNASSIGNED:In May 2021, using an established online panel, KnowledgePanel, we surveyed older US adults aged 65-84 years without history of ASCVD on outcome preferences related to statin therapy (benefit outcomes to be reduced by the therapy: heart attack, stroke; adverse effects: diabetes, abnormal liver test, muscle pain) or aspirin therapy (benefit outcomes: heart attack, stroke; adverse effects: brain bleed, bowel bleed, stomach ulcer). We used standardized best-worst scores (range of -1 for "least worrisome" to +1 for "most worrisome") and conditional logistic regression to examine the relative importance of the outcomes. RESULTS/UNASSIGNED:In this study, 607 ASCVD-free participants (median age 74, 46% male, 81% White) were included; 304 and 303 completed the statin and aspirin versions of the survey, respectively. For statin-related outcomes, stroke and heart attack were most worrisome (score 0.55; 95% CI 0.51, 0.60) and (0.53; 0.48, 0.58), followed by potential harms of diabetes (-0.07; -0.10, -0.03), abnormal liver test (-0.25; -0.29, -0.20), and muscle pain (-0.77; -0.82, -0.73). For aspirin-related outcomes, stroke and heart attack were similarly most worrisome (0.48; 0.43, 0.52) and (0.43; 0.38, 0.48), followed by brain bleed (0.30; 0.25, 0.34), bowel bleed (-0.31; -0.33, -0.28), and stomach ulcer (-0.90; -0.92, -0.87). Conditional logistic regression and subgroup analyses by age, sex, and race yielded similar results. CONCLUSIONS/UNASSIGNED:Older adults generally consider outcomes related to benefits of ASCVD primary preventive therapies-stroke and heart attack-more important than their adverse effects. Integrating patient preferences with risk assessment is an important next step for personalizing ASCVD preventive therapies for older adults.

Since the pandemic began in December 2019, SARS-Cov2 has accentuated the wide gap and disparities in socioeconomic and healthcare access at individual, community, country, and regional levels. More than two years into the current pandemic, up to three-fourths of the patients are reporting continued signs and symptoms beyond the acute phase of COVID-19, and Long COVID portends to be a major challenge in the future ahead. With a comprehensive overview of the literature, we found that most studies concerning long COVID came from high and upper-middle income countries, and people of low-income and lower-and-middle income regions and vulnerable groups with comorbid conditions have been neglected. Apart from the level of income, there is a significant geographical heterogeneity in investigating the Post-Acute Sequelae of COVID-19 (PASC) or what we call now, long COVID. We believe that these recognizing health disparities is crucial from equity perspective and is the first step toward global health promotion.
