Interactions with the police may result in police brutality, particularly for people of color. Black men who have sex with men (BMSM) face disproportionate risk of police contact and may experience elevated violence risk. We measured longitudinal associations between discriminatory police harassment (DPH) and subsequent risk of a range of interpersonal violence experiences, including intimate partner violence (IPV). In this study, we estimated associations between DPH motivated by racism, homophobia, or both, and subsequent violent experiences (being physically harassed, hit, threatened with weapons, and intimate partner violence) among BMSM. Bivariate and multivariable regression analyses were used to control for demographic and behavioral factors. Among 1160 BMSM included at 12-month follow-up, experiencing DPH motivated by racism and homophobia was associated with over four times the odds of being threatened with violence (AOR 4.85, 95% CI 3.20, 7.33), four times the odds of or experiencing violence defined as being punched, kicked, or beaten, or having an object thrown at them (AOR 4.51, 95% CI 2.82, 7.19), and nearly three times the odds of physical partner abuse (AOR 3.49, 95% CI 1.69, 7.19). Findings suggest that for BMSM, DPH is associated with the threat and experience of violence, with a dose-response relationship between DPH motivated by one or more causes. Given that BMSM are a population particularly vulnerable to both police harassment related to race and sexual orientation and violence coupled with stigma, additional research evaluating mechanisms linking these associations is needed in order to develop additional supportive interventions.

There have long been noted significant health disparities related to cancer in populations comprised of low-income and minority individuals, including those with gynecologic cancers. Compliance with appointments related to cancer care is critical to ensuring timely diagnosis, treatment, and detection of disease progression. At a public safety net hospital in New York City, the rate of clinic absenteeism in gynecologic oncology clinic was noted to be nearly 20%. This prospective, survey-based study catalogued reasons for clinic absenteeism and noted that the most common reason an appointment was missed was the patient being unaware it existed. Next most common reasons were medical conflicts and family obligations. Patients at this clinic would benefit from a clinic navigator to assist with scheduling appointments, remind patients of upcoming appointments, and resolve conflicting medical appointments.

The prevalence of type 2 diabetes in youth has increased substantially, yet the genetic underpinnings remain largely unexplored. To identify genetic variants predisposing to youth-onset type 2 diabetes, we formed ProDiGY, a multi-ethnic collaboration of three studies (TODAY, SEARCH, and T2D-GENES) with 3,006 youth type 2 diabetes cases (mean age 15.1±2.9 y) and 6,061 diabetes-free adult controls (mean age 54.2±12.4 y). After stratifying by principal component-clustered ethnicity, we performed association analyses on ∼10 million imputed variants using a generalized linear mixed model incorporating a genetic relationship matrix to account for population structure and adjusting for sex. We identified 7 genome-wide significant loci, including the novel locus rs10992863 in PHF2 (P=3.2×10^-8, odds ratio [OR]=1.23). Known loci identified in our analysis include rs7903146 in TCF7L2 (P=8.0×10^-20, OR 1.58), rs72982988 near MC4R (P=4.4×10^-14, OR=1.53), rs200893788 in CDC123 (P=1.1×10^-12, OR= 1.32), rs2237892 in KCNQ1 (P=4.8×10^-11, OR=1.59), rs937589119 in IGF2BP2 (P=3.1×10^-9, OR=1.34) and rs113748381 in SLC16A11 (P=4.1×10^-8, OR=1.04). Secondary analysis with 856 diabetes-free youth controls uncovered an additional locus in CPEB2 (P=3.2×10^-8, OR=2.1) and consistent direction of effect for diabetes risk. In conclusion, we identified both known and novel loci in the first genome wide association study (GWAS) of youth-onset type 2 diabetes.

BACKGROUND:Prenatal development is a time when the brain is acutely vulnerable to insult and alteration by environmental factors (e.g., toxins, maternal health). One important risk factor is maternal obesity (Body Mass Index > 30). Recent research indicates that high maternal BMI during pregnancy is associated with increased risk for numerous physical health, cognitive, and mental health problems in offspring across the lifespan. It is possible that heightened maternal prenatal BMI influences the developing brain even before birth. METHODS:The present study examines this possibility at the level of macrocircuitry in the human fetal brain. Using a data-driven strategy for parcellating the brain into subnetworks, we test whether MRI functional connectivity within or between fetal neural subnetworks varies with maternal prenatal BMI in 109 fetuses between the ages of 26 and 39weeks. RESULTS:We discovered that strength of connectivity between two subnetworks, left anterior insula/inferior frontal gyrus (aIN/IFG) and bilateral prefrontal cortex (PFC), varied with maternal BMI. At the level of individual aIN/IFG-PFC connections, we observed both increased and decreased between-network connectivity with a tendency for increased within-hemisphere connectivity and reduced cross-hemisphere connectivity in higher BMI pregnancies. Maternal BMI was not associated with global differences in network topography based on network-based statistical analyses. CONCLUSIONS:Overall effects were localized in regions that will later support behavioral regulation and integrative processes, regions commonly associated with obesity-related deficits. By establishing onset in neural differences prior to birth, this study supports a model in which maternal BMI-related risk is associated with fetal connectome-level brain organization with implications for offspring long-term cognitive development and mental health.

Background: Home blood pressure measurement (HBPM) has been a time-honored supplement to periodic in-office measurement to facilitate primary care physician (PCP) diagnosis of hypertension (HTN), its ongoing control and medication management. PCPs, in response to COVID-19, adopted telemedicine as the sole means of care, elevating HBPM as the essential HTN surveillance tool. We assessed the feasibility of this approach in a Veteran Affairs (VA) geriatric clinic.
Method(s): Study subjects included all the Veterans seen by New York Harbor VA geriatrics fellows' clinic between January 1, 2019 and March 1, 2020 and who have HTN listed as an electronic health record (EHR) diagnosis. Those with systolic blood pressure (SBP) > 140 mmHg were prioritized. We called these patients to assess adherence to BP self-care and reconcile medications, to identify reasons for poor adherence and to offer solutions. Patients were called again within two months to re-assess adherence, collect BP measures and adjust medications as needed.
Result(s): Among 102 patients diagnosed with HTN, 41 had not achieved the goal of SBP <140 mmHg prior to this intervention. We reached 78% (n=32) of these 41 patients (requiring 1-3 phone calls). All reported medical adherence, but none were found to consistently check BP at home with any frequency or proper technique. For the 14 patients having no BP monitor at home, we sent a monitor to 10 through prescription and enrolled 4 in a home telehealth (HT) program that uses daily remote measurement. We provided detailed instruction of proper HBPM during the initial interview. At follow-up, 47% (n=15) practiced HBPM and reported BP readings within goal, indicating no need for change in care. Of these 15, 11 had their own BP monitors; 2 achieved control through the HT program. However, only 2 of the 10 patients who received the prescribed BP monitor started HBPM and demonstrated good control.
Conclusion(s): Given our reliance on telemedicine, HBPM is feasible for outpatient HTN management. Close PCP follow-up to encourage consistent HBPM practice may improve and sustain the success of this strategy. The quality of self-reported data should be assessed during office visits

Background: Hearing loss compounds social isolation. We tested acceptability and benefit of simple hearing assistance devices- Personal Amplifiers (PAs)-provided to older people with hearing loss and risk for social isolation, loneliness and depression.
Method(s): We conducted a pre-post pilot trial with 1-and 2-month follow-up of residents of six low-income senior apartment buildings in Los Angeles (n = 74) who had hearing difficulties, based on either (A) >= 10 (range 0-40) on the Hearing Handicap Inventory - Survey; or (B) hearing loss based on a clinically validated audiological iPad assessment (SHOEBOXTM) with surveys at 0, 1 and 2 months using 4 instruments: (1) Social Isolation Score (SIS); (2) Patient Health Questionnaire (PHQ-9); (3) Sense of Social Support scale; and (4) DG Loneliness Scale. We assessed PA use and perceived benefit using the International Outcome Inventory for Alternative Interventions (IOI-AI).
Result(s): Baseline characteristics and degree of hearing problems did not vary significantly among 74 initial enrollees. Fortytwo residents completed 1-and 2-month surveys. Mean age was 78.2 years; 64% were women; 83% scored >=10 on HHI-S and 83% met SHOEBOX criteria for hearing loss. At baseline, 31% met SIS criteria for social isolation (>=2; mean=1.0; SD:0.98); 41% met DG criteria for loneliness; and 19% had low social support. Mean PHQ-9 was 7.0, (SD:5.3); 26% had moderate to severe mood symptoms. At 2-month follow up, 87% reported PA use of >= one hour/day, and 76% indicated that the device changed life enjoyment 'quite a lot.' Psychosocial measures improved over time.
Conclusion(s): In a vulnerable older population with hearing difficulties, simple PAs were enthusiastically received and may have improved social functioning and mood. Further work with stronger study designs is needed to shed more light on the effectiveness of this approach

BACKGROUND/OBJECTIVES/OBJECTIVE:Poor communication is a barrier to care for people with hearing loss. We assessed the feasibility and potential benefit of providing a simple hearing assistance device during an emergency department (ED) visit, for people who reported difficulty hearing. DESIGN/METHODS:Randomized controlled pilot study. SETTING/METHODS:The ED of New York Harbor Manhattan Veterans Administration Medical Center. PARTICIPANTS/METHODS:One hundred and thirty-three Veterans aged 60 and older, presenting to the ED, likely to be discharged to home, who either (1) said that they had difficulty hearing, or (2) scored 10 or greater (range 0-40) on the Hearing Handicap Inventory-Survey (HHI-S). INTERVENTION/METHODS:Subjects were randomized (1:1), and intervention subjects received a personal amplifier (PA; Williams Sound Pocketalker 2.0) for use during their ED visit. MEASUREMENTS/METHODS:Three survey instruments: (1) six-item Hearing and Understanding Questionnaire (HUQ); (2) three-item Care Transitions Measure; and (3) three-item Patient Understanding of Discharge Information. Post-ED visit phone calls to assess ED returns. RESULTS:Of the 133 subjects, 98.3% were male; mean age was 76.4 years (standard deviation (SD) = 9.2). Mean HHI-S score was 19.2 (SD = 8.3). Across all HUQ items, intervention subjects reported better in-ED experience than controls. Seventy-five percent of intervention subjects agreed or strongly agreed that ability to understand what was said was without effort versus 56% for controls. Seventy-five percent of intervention subjects versus 36% of controls said clinicians provided them with an explanation about presenting problems. Three percent of intervention subjects had an ED revisit within 3 days compared with 9.0% controls. CONCLUSION/CONCLUSIONS:Veterans with hearing difficulties reported improved in-ED experiences with use of PAs, and were less likely to return to the ED within 3 days. PAs may be an important adjunct to older patient ED care but require validation in a larger more definitive randomized controlled trial.

CONTEXT/BACKGROUND:In preclinical studies, high androgen levels during pregnancy are associated with low birth weight and rapid postnatal weight gain in the offspring. However, human data linking prenatal androgens with birth weight and early life weight gain in the offspring are scarce. DESIGN/METHODS:We evaluated 516 mother-child pairs enrolled in the New England birth cohorts of the Collaborative Perinatal Project (1959-1966). We assayed androgen bioactivity in maternal sera during third-trimester using a receptor-mediated luciferase expression bioassay. Age and sex-specific BMI Z-scores (BMIz), defined using established standards, were assessed at birth, 4 months, 1 year, 4 years, and 7 years. We used linear mixed models to evaluate the relation of maternal androgens with childhood BMIz overall and by sex. We examined the association of maternal androgens with fetal growth restriction. The association of weight trajectories with maternal androgens was examined using multinomial logistic regression. RESULTS:Higher maternal androgen levels associated with lower BMIz at birth (β = - 0.39, 95% CI: - 0.73, - 0.06); this relation was sex-dependent, such that maternal androgens significantly associated with BMIz at birth in girls alone (β = - 0.72, 95% CI: - 1.40, - 0.04). The relation of maternal androgens with fetal growth restriction revealed dose threshold effects that differed by sex. There was no significant association between maternal androgens and weight trajectory overall. However, we found a significant sex interaction (p = 0.01); higher maternal androgen levels associated with accelerated catch-up growth in boys (aOR = 2.14, 95% CI: 1.14, 4.03). CONCLUSION/CONCLUSIONS:Our findings provide evidence that maternal androgens may have differential effects on the programming of intrauterine growth and postnatal weight gain depending on fetal sex.
