The Association Between Back Pain, Depression, and Quality of Life Among Older Adults Living with HIV in Rural Areas of the United States.

INTRODUCTION: This study aimed to assess prevalence of back pain among older people living with HIV (PLH) in rural areas of the United States (US); compare the presence of comorbidities, socioeconomic factors, and sociodemographic factors among older PLH in rural areas of the US with and without back pain; and examine the associations between back pain, depression, and QOL among older PLH in rural areas of the US. METHODS: Cross-sectional data was collected among US rural dwelling PLH of at least 50 years of age. Multiple logistic regression was performed to examine the association between back pain and depression. Multiple linear regression was performed to assess the association between back pain and QOL. RESULTS: A total of 38.8% (n = 164) of participants self-reported back pain. PLH with back pain were more likely to have depression (60.87%, n = 98). PLH with back pain had lower mean QOL scores (53.01 ± 18.39). Back pain was associated with greater odds of having depression (OR 1.61 [CI 0.99-2.61], p = .054) and was significantly associated with lower QOL (p < .001). CONCLUSIONS: Prevention strategies to reduce back pain and poor HIV outcomes among PLH living in rural areas of the US are needed.

The impact of androgen deprivation therapy on bone microarchitecture in men with prostate cancer: A longitudinal observational study (The ANTELOPE Study).

Introduction: Androgen Deprivation Therapy (ADT) for prostate cancer (PC) has substantial negative impacts on the musculoskeletal system and body composition. Many studies have focused on the effects of ADT on areal bone mineral density (aBMD), but aBMD does not capture key determinants of bone strength and fracture risk, for example volumetric bone density (vBMD), geometry, cortical thickness and porosity, trabecular parameters and rate of remodelling. More specialist imaging techniques such as high-resolution peripheral quantitative computed tomography (HR-pQCT) have become available to evaluate these parameters. Although it has previously been demonstrated that bone microarchitectural deterioration occurs in men undergoing ADT, the aim of the ANTELOPE study was to examine longitudinal changes in bone microstructure alongside a range of musculoskeletal parameters and frailty, comparing men with PC receiving ADT alone or ADT plus chemotherapy for metastatic disease, with a healthy age-matched population. Methods: We used HR-pQCT to investigate effects of 12 months of ADT on vBMD and microstructural parameters, complemented by assessment of changes in aBMD, serum bone turnover markers, sex hormones, body composition, grip strength, physical and muscle function, frailty and fracture risk. We studied three groups: Group A - men with localised/locally advanced PC due to commence ADT; Group B - men with newly diagnosed hormone-sensitive, metastatic PC, starting ADT alongside docetaxel chemotherapy and steroids; Group C - healthy, age-matched men. The primary endpoint was change in vBMD (Group A vs Group C) at the distal radius. Results: Ninety-nine participants underwent baseline study assessments (Group A: n = 38, Group B: n = 30 and Group C: n = 31). Seventy-five participants completed all study assessments (Group A (29), Group B (18), Group C (28). At baseline, there were no significant differences between Groups A and C in any of the BMD or bone microstructure outcomes of interest. After 12 months of ADT treatment, there was a significantly greater decrease in vBMD (p < 0.001) in Group A (mean 12-month change = -13.7 mg HA/cm3, -4.1 %) compared to Group C (mean 12-month change = -1.3 mg HA/cm3, -0.4 %), demonstrating achievement of primary outcome. Similar effects were observed when comparing the change in vBMD between Group B (mean 12-month change = -13.5 mg HA/cm3, -4.3 %) and Group C. These changes were mirrored in aBMD. ADT resulted in microstructural deterioration, a reduction in estimated bone strength and an increase in bone turnover. There was evidence of increase in total fat mass and trunkal fat mass in ADT-treated patients, with marked loss in upper limb mass, along with BMI gain. Frailty increased and physical performance and strength deteriorated in both ADT groups, relative to the healthy control group. Conclusion: The study showed that ADT has profound effects on vBMD, aBMD, bone microstructure and strength and body composition, and important impacts on frailty and physical performance. Whilst DXA remains a valuable tool (changes in aBMD are of the same magnitude as those observed for vBMD), HR-pQCT should be considered for assessing the effects of anti-androgens and other newer PC therapies on bone, as well as potential mitigation by bone-targeted agents.

Factors predicting primary and booster COVID-19 vaccination in a community sample of African American men and women in the United States Midwest.

COVID-19 has disproportionately burdened impoverished minority communities. This study recruited an age- and gender-diverse community sample of 541 Black adults in a United States Midwestern city with large racial health disparities, with the aim of examining factors associated with COVID-19 vaccination. All participants completed measures assessing their COVID-19 vaccination status (unvaccinated, received primary vaccination, or received primary plus booster vaccination) as well as demographic characteristics, socioeconomic factors, health and health system factors, and health behavior theory constructs related to vaccination. In this predominantly low-income sample, 55% of participants had received primary COVID-19 vaccination and 31% of the sample had received a booster dose. Multiple regression analyses established that having primary vaccination was significantly predicted by older age, political identification as Democrat, education beyond high school, barriers to accessing health care, as well as higher trust of vaccine benefits, less preference for natural immunity, stronger social norms favoring vaccination, and perceiving higher levels of collective responsibility. Surprisingly, higher global medical mistrust and difficulty with healthcare access were associated with vaccination. The model explained 76% of the variance in primary COVID-19 vaccination. Having received a COVID-19 booster was predicted by older age, previous COVID-19 infection, higher trust in vaccine benefits, and fewer worries about unforeseen future effects of vaccination. Study findings identified factors associated with COVID-19 vaccine uptake in racial minority communities, and support the benefits of interventions that harness social network supports for vaccination, address community vaccine concerns, and appeal to collective responsibility to promote vaccine uptake.

Amniocentesis in pregnancies at or beyond 24 weeks: an international multicenter study.

BACKGROUND: Amniocentesis for genetic diagnosis is most commonly done between 15 and 22 weeks of gestation but can be performed at later gestational ages. The safety and genetic diagnostic accuracy of amniocentesis have been well-established through numerous large-scale multicenter studies for procedures before 24 weeks, but comprehensive data on late amniocentesis remain sparse. OBJECTIVE: To evaluate the indications, diagnostic yield, safety, and maternal and fetal outcomes associated with amniocentesis performed at or beyond 24 weeks of gestation. STUDY DESIGN: We conducted an international multicenter retrospective cohort study examining pregnant individuals who underwent amniocentesis for prenatal diagnostic testing at gestational ages between 24w0d and 36w6d. The study, spanning from 2011 to 2022, involved 9 referral centers. We included singleton or twin pregnancies with documented outcomes, excluding cases where other invasive procedures were performed during pregnancy or if amniocentesis was conducted for obstetric indications. We analyzed indications for late amniocentesis, types of genetic tests performed, their results, and the diagnostic yield, along with pregnancy outcomes and postprocedure complications. RESULTS: Of the 752 pregnant individuals included in our study, late amniocentesis was primarily performed for the prenatal diagnosis of structural anomalies (91.6%), followed by suspected fetal infection (2.3%) and high-risk findings from cell-free DNA screening (1.9%). The median gestational age at the time of the procedure was 28w5d, and 98.3% of pregnant individuals received results of genetic testing before birth or pregnancy termination. The diagnostic yield was 22.9%, and a diagnosis was made 2.4 times more often for fetuses with anomalies in multiple organ systems (36.4%) compared to those with anomalies in a single organ system (15.3%). Additionally, the diagnostic yield varied depending on the specific organ system involved, with the highest yield for musculoskeletal anomalies (36.7%) and hydrops fetalis (36.4%) when a single organ system or entity was affected. The most prevalent genetic diagnoses were aneuploidies (46.8%), followed by copy number variants (26.3%) and monogenic disorders (22.2%). The median gestational age at delivery was 38w3d, with an average of 59 days between the procedure and delivery date. The overall complication rate within 2 weeks postprocedure was 1.2%. We found no significant difference in the rate of preterm delivery between pregnant individuals undergoing amniocentesis between 24 and 28 weeks and those between 28 and 32 weeks, reinforcing the procedure's safety across these gestational periods. CONCLUSION: Late amniocentesis, at or after 24 weeks of gestation, especially for pregnancies complicated by multiple congenital anomalies, has a high diagnostic yield and a low complication rate, underscoring its clinical utility. It provides pregnant individuals and their providers with a comprehensive diagnostic evaluation and results before delivery, enabling informed counseling and optimized perinatal and neonatal care planning.

Maternal Graves Disease Postthyroidectomy With Fetal Thyrotoxicosis and Goiter.

Fetal thyrotoxicosis is a rare condition with high morbidity and mortality. It may complicate pregnancies in women with a history of Graves disease (GD) when transplacental passage of maternal TSH receptor antibodies stimulate the fetal thyroid gland and cause hyperthyroidism. We report the case of a 34-year-old woman with a history of GD and prior thyroidectomy, where fetal thyrotoxicosis at 21 weeks of gestation was suspected due to prenatal ultrasound findings of cardiac failure and fetal goiter. She was treated with high-dose carbimazole and followed closely by a multidisciplinary team. Her baby was delivered in good condition at 34 weeks' gestation and developed hyperthyroidism in the days after birth, which was successfully treated medically. This case highlights the importance of awareness of the condition among women with a history of GD, as well as the necessity for prompt diagnosis and treatment of this complex disease.

Coronavirus Disease 2019 Vaccination by Gender and Age in a Sample of Black Adults in Chicago.

Although vaccine behaviors differ greatly by gender and age, few studies have examined vaccination at the intersection of gender and age within the Black community. We examined COVID-19 vaccination by gender and age using a survey of over 500 Black adults in Chicago, Illinois, fielded from September 2021 to March 2022. Although 54% had received at least one COVID-19 vaccine, the proportion vaccinated was considerably lower for Black men (28%) and women (37%) under 40 years old than Black men (92%) and women (86%) over 40 years (p < .001). Concern about vaccine side effects was the most reported barrier for unvaccinated women (56%) and men (38%) under 40 years. Our results suggest that targeted efforts to improve COVID-19 vaccine uptake in the Black community in Chicago after the initial rollout should have focused on young adults, particularly young Black men, with emphasis on addressing concern about vaccine side effects.

An exploratory study of community violence and HIV care engagement among Black gay and bisexual men.

This study examined the relationship between exposure to community violence and HIV care engagement among 107 Black gay or bisexual men living with HIV in Chicago. Measures assessed the importance of demographic covariates (age, annual income, health insurance status, and years living with HIV), community violence exposures, mental health, social support, in explaining variations in missed doses of antiretroviral therapy (ART) medication and missed HIV care appointments. Results showed that participants who reported higher rates of exposure to community violence were two times more likely to have missed ART doses and HIV care appointments. Participants who reported depression scores were two times more likely to have greater non-ART adherence. Finally, older participants were more likely to report fewer missed ART doses. More research is needed to clarify the mechanisms between age or depression and ART adherence given community violence exposure. Health care providers should screen for depression when attempting to promote better ART adherence and keeping HIV care appointments for Black gay and bisexual men living with HIV. Younger Black gay and bisexual men living with HIV may be more vulnerable than older men for missed ART doses and may require additional screening and follow-up.

Estimating fetal weight in gastroschisis: A 10 year audit of outcomes at the National Maternity Hospital.

OBJECTIVE: To identify whether conventional methods of estimating fetal growth (Hadlock's formula), which relies heavily on abdominal circumference measurements, are accurate in fetuses with gastroschisis. METHODS: A retrospective cohort study was performed between the period January 1, 2011 and December 31, 2021 in a tertiary referral maternity hospital identifying all pregnancies with a diagnosis of gastroschisis. Projected fetal weight was obtained using the formula (EFW [Hadlock's formula] + 185 g × [X/7]) where X was the number of days to delivery. RESULTS: During the study period 41 cases were identified. The median maternal age was 25. The median BMI was 25 and 63% were primiparous women (n = 26). Median gestation at diagnosis was 21 weeks. Median gestation at delivery was 36 weeks. A total of 4.8% of mothers had a history of drug use (n = 2). The rate of maternal tobacco use was 21.9% (n = 9). A total of 4.8% of fetuses had additional congenital anomalies including amniotic band syndrome and myelomeningocele (n = 2). Estimated fetal weight (EFW) and birth weight data were available for 34 cases. A Wilcoxon signed-rank test showed projected EFW using Hadlock's formula did not result in a statistically significant different birth weight (Z = -1.3, P = 0.169). Median projected weight and actual birth weight were 2241.35 and 2415 g respectively. Median difference was 0.64 g (95% CI: -148 to -28.5). CONCLUSION: Our data showed accuracy using standard formulae for EFW in fetuses with gastroschisis.

Automatic segmentation of skeletal muscles from MR images using modified U-Net and a novel data augmentation approach.

Rapid and accurate muscle segmentation is essential for the diagnosis and monitoring of many musculoskeletal diseases. As gold standard, manual annotation suffers from intensive labor and high inter-operator reproducibility errors. In this study, deep learning (DL) based automatic muscle segmentation from MR scans is investigated for post-menopausal women, who normally experience a decline in muscle volume. The performance of four Deep Learning (DL) models was evaluated: U-Net and UNet++ and two modified U-Net networks, which combined feature fusion and attention mechanisms (Feature-Fusion-UNet, FFU, and Attention-Feature-Fusion-UNet, AFFU). The models were tested for automatic segmentation of 16-lower limb muscles from MRI scans of two cohorts of post-menopausal women (11 subjects in PMW-1, 8 subjects in PMW-2; from two different studies so considered independent datasets) and 10 obese post-menopausal women (PMW-OB). Furthermore, a novel data augmentation approach is proposed to enlarge the training dataset. The results were assessed and compared by using the Dice similarity coefficient (DSC), relative volume error (RVE), and Hausdorff distance (HD). The best performance among all four DL models was achieved by AFFU (PMW-1: DSC 0.828 ± 0.079, 1-RVE 0.859 ± 0.122, HD 29.9 mm ± 26.5 mm; PMW-2: DSC 0.833 ± 0.065, 1-RVE 0.873 ± 0.105, HD 25.9 mm ± 27.9 mm; PMW-OB: DSC 0.862 ± 0.048, 1-RVE 0.919 ± 0.076, HD 34.8 mm ± 46.8 mm). Furthermore, the augmentation of data significantly improved the DSC scores of U-Net and AFFU for all 16 tested muscles (between 0.23% and 2.17% (DSC), 1.6%-1.93% (1-RVE), and 9.6%-19.8% (HD) improvement). These findings highlight the feasibility of utilizing DL models for automatic segmentation of muscles in post-menopausal women and indicate that the proposed augmentation method can enhance the performance of models trained on small datasets.

Guideline No. 448: Prevention of Rh D Alloimmunization.

OBJECTIVE: This guideline provides recommendations for the prevention of Rh D alloimmunization (isoimmunization) in pregnancy, including parental testing, routine postpartum and antepartum prophylaxis, and other clinical indications for prophylaxis. Prevention of red cell alloimmunization in pregnancy with atypical antigens (other than the D antigen), for which immunoprophylaxis is not currently available, is not addressed in this guideline. TARGET POPULATION: All Rh D-negative pregnant individuals at risk for Rh D alloimmunization due to potential exposure to a paternally derived fetal Rh D antigen. OUTCOMES: Routine postpartum and antepartum Rh D immunoprophylaxis reduces the risk of Rh D alloimmunization at 6 months postpartum and in a subsequent pregnancy. BENEFITS, HARMS, AND COSTS: This guideline details the population of pregnant individuals who may benefit from Rho(D) immune globulin (RhIG) immunoprophylaxis. Thus, those for whom the intervention is not required may avoid adverse effects, while those who are at risk of alloimmunization may mitigate this risk for themselves and/or their fetus. EVIDENCE: For recommendations regarding use of RhIG, Medline and Medline in Process via Ovid and Embase Classic + Embase via Ovid were searched using both the trials and observational studies search strategies with study design filters. For trials, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Database of Abstracts of Reviews of Effects via Ovid were also searched. All databases were searched from January 2000 to November 26, 2019. Studies published before 2000 were captured from the grey literature of national obstetrics and gynaecology specialty societies, luminary specialty journals, and bibliographic searching. A formal process for the systematic review was undertaken for this update, as described in the systematic review manuscript published separately. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the SOGC's modified GRADE approach. See Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations). INTENDED AUDIENCE: The intended users of this guideline include prenatal care providers such as obstetricians, midwives, family physicians, emergency room physicians, and residents, as well as registered nurses and nurse practitioners. TWEETABLE ABSTRACT: An updated Canadian guideline for prevention of Rh D alloimmunization addresses D variants, cffDNA for fetal Rh type, and updates recommendations on timing of RhIG administration. SUMMARY STATEMENTS: RECOMMENDATIONS.

Associations Between Religiosity and Medical Mistrust: An Age-Stratified Analysis of Survey Data from Black Adults in Chicago.

Medical mistrust is associated with poor health outcomes, ineffective disease management, lower utilization of preventive care, and lack of engagement in research. Mistrust of healthcare systems, providers, and institutions may be driven by previous negative experiences and discrimination, especially among communities of color, but religiosity may also influence the degree to which individuals develop trust with the healthcare system. The Black community has a particularly deep history of strong religious communities, and has been shown to have a stronger relationship with religion than any other racial or ethnic group. In order to address poor health outcomes in communities of color, it is important to understand the drivers of medical mistrust, which may include one's sense of religiosity. The current study used data from a cross-sectional survey of 537 Black individuals living in Chicago to understand the relationship between religiosity and medical mistrust, and how this differs by age group. Descriptive statistics were used to summarize data for our sample. Adjusted stratified linear regressions, including an interaction variable for age group and religiosity, were used to model the association between religiosity and medical mistrust for younger and older people. The results show a statistically significant relationship for younger individuals. Our findings provide evidence for the central role the faith-based community may play in shaping young peoples' perceptions of medical institutions.

Trusted Sources of Information and COVID-19 Vaccination Among Black Adults in Chicago.

PURPOSE: Examine trust in sources of COVID-19 information and vaccination status. DESIGN: Cross-sectional. SETTING: Chicago, Illinois. SUBJECTS: Convenience sample of 538 Black adults surveyed between September 2021 and March 2022. MEASURES: Trust in sources of COVID-19 information, COVID-19 vaccination. ANALYSIS: Using latent class analysis, we identified classes of trust in sources of COVID-19 information. We considered predictors of class membership using multinomial logistic regression and examined unadjusted and adjusted associations between trust class membership and COVID-19 vaccination while accounting for uncertainty in class assignment. RESULTS: Our analytic sample (n = 522) was predominantly aged 18-34 (52%) and female (71%). Results suggested a four-class solution: (1) low trust, (2) high trust in all sources, (3) high trust in doctor and government, and (4) high trust in doctor, faith leader, and family. Unadjusted odds of vaccination were greater in the high trust in all sources (OR 2.0, 95% CI 1.2-3.2), high trust in doctor and government (OR 2.7, 95% CI 1.4-5.3), and high trust in doctor, faith leader, and family classes (OR 2.1, 95% CI 1.2, 3.9) than the low trust class. However, these associations were not significant after adjustment for sociodemographic and health status factors. CONCLUSION: Although COVID-19 vaccination varied across trust classes, our adjusted findings do not suggest a direct association between trust and vaccination, reflecting complexities in the vaccine decision-making process.

Glucocorticoid prescribing in neurology.

Glucocorticoids are commonly used for neurological disorders, but they can have significant adverse effects, including adrenal insufficiency, hyperglycaemia, osteoporosis and increased infection risk. Long-term use of corticosteroids requires the prescriber to plan risk mitigation, including monitoring and often coprescribing. This article highlights the potential risks of corticosteroid prescribing and draws together up-to-date guidance with multispecialty input to clarify ways of reducing those risks. We discuss home blood glucose monitoring and consider a steroid safety checklist to promote safer steroid prescribing.

Ecological characteristics explain neutral genetic variation of three coastal sparrow species.

Eco-phylogeographic approaches to comparative population genetic analyses allow for the inclusion of intrinsic influences as drivers of intraspecific genetic structure. This insight into microevolutionary processes, including changes within a species or lineage, provides better mechanistic understanding of species-specific interactions and enables predictions of evolutionary responses to environmental change. In this study, we used single nucleotide polymorphisms (SNPs) identified from reduced representation sequencing to compare neutral population structure, isolation by distance (IBD), genetic diversity and effective population size (Ne) across three closely related and co-distributed saltmarsh sparrow species differing along a specialization gradient-Nelson's (Ammospiza nelsoni subvirgata), saltmarsh (A. caudacuta) and seaside sparrows (A. maritima maritima). Using an eco-phylogeographic lens within a conservation management context, we tested predictions about species' degree of evolutionary history and ecological specialization to tidal marshes, habitat, current distribution and population status on population genetic metrics. Population structure differed among the species consistent with their current distribution and habitat factors, rather than degree of ecological specialization: seaside sparrows were panmictic, saltmarsh sparrows showed hierarchical structure and Nelson's sparrows were differentiated into multiple, genetically distinct populations. Neutral population genetic theory and demographic/evolutionary history predicted patterns of genetic diversity and Ne rather than degree of ecological specialization. Patterns of population variation and evolutionary distinctiveness (Shapely metric) suggest different conservation measures for long-term persistence and evolutionary potential in each species. Our findings contribute to a broader understanding of the complex factors influencing genetic variation, beyond specialist-generalist status and support the role of an eco-phylogeographic approach in population and conservation genetics.

Factors associated with PrEP use in a community sample of African American men who have sex with men (MSM) and transgender women (TGW) in the United States Midwest.

Black sexual minority men who have sex with men (MSM) in the United States are at disparate risk for contracting HIV infection, but pre-exposure prophylaxis (PrEP) use is suboptimal. Social network methods were used to recruit a community sample of racial minority MSM and transgender women (TGW) in two Midwestern US cities. 250 PrEP-eligible (HIV-negative) participants completed measures assessing current and intended PrEP use; demographic characteristics; PrEP knowledge, attitudes, norms, stigma, and self-efficacy; and structural barriers to PrEP. Multivariate analyses established predictors of current and intended PrEP use. Only 12% of participants reported currently using PrEP, which was associated with greater PrEP knowledge and not having a main partner, with trends for greater PrEP use by younger participants and those with partners living with HIV. Among participants not currently on PrEP, strength of PrEP use intentions was associated with higher PrEP knowledge, PrEP descriptive social norms, and PrEP use self-efficacy. This study is among few to directly compare Black who have adopted PrEP with those who have not. Its findings underscore the potential benefits of employing social network approaches for strengthening PrEP use peer norms, increasing PrEP knowledge and self-efficacy, and optimizing PrEP uptake among racial minority MSM and TGW.

Police Violence Experienced by Black Gay and Bisexual Men: The Effects on HIV Care Engagement and Medication Adherence.

Black men face high rates of police violence, including direct victimization and indirect exposure to or knowledge of harmful policing. This violence can result in death and physical harm, as well as in numerous poor mental health outcomes. There has been little research examining experiences of police violence experienced by Black gay and bisexual men or the effects of police brutality on HIV continuum of care outcomes. To address this important gap, in this exploratory study, we examined the effects of police brutality on engagement in HIV care and adherence to antiretroviral medications. Cross-sectional survey data were collected from 107 Black gay and bisexual men living with HIV. The path analysis showed that men with greater exposure to police violence had increased symptoms of post-traumatic stress disorder and were more likely to have missed HIV care appointments in the past year. Additionally, there was a significant indirect effect of exposure to police violence on missed medication doses via PTSD symptoms.

Perceptions of X+Y Scheduling Among Combined Internal Medicine-Pediatrics Residency Trainees: A Qualitative Program Evaluation.

OBJECTIVE: The study aims to elicit perceived benefits and downsides of X+Y scheduling for combined Internal Medicine-Pediatrics (Med-Peds) residents via focus groups. METHODS: Five focus groups were conducted with Med-Peds residents in participating programs which utilized X+Y scheduling. Onefocus group was held per participating institution. Each focus group was facilitated by a chief resident from a different participating institution. Questions were developed by the study team after a review of the literature and local experience with X+Y scheduling and included open-ended questions. Focus groups were recorded and transcribed. Transcripts were reviewed by study team members, and representative themes and quotes were presented. The main outcome was to evaluate the perceived benefits and downsides of X+Y scheduling for Med-Peds. RESULTS: Results from four of the five focus groups were fully reviewed. Themes regarding the benefits of X+Y scheduling included (1) improved inpatient and outpatient experience, (2) predictability in schedule which improved wellness, and (3) longitudinal time for career exploration. Downsides of X+Y scheduling were highlighted as well including (1) condensing too many experiences into Y time and (2) challenges that exist when categorical medicine and pediatrics programs use different block schedules. CONCLUSIONS: X+Y schedules create potential solutions for longstanding barriers to medical education and notably conflict with inpatient and outpatient responsibilities. Our data shows similar benefits to X+Y scheduling for combined residents as for their categorical colleagues and sheds light on some unique considerations for combined programs and trainees. Additional studies should continue to assess the effect of X+Y scheduling on our combined trainees.

Acceptability, Feasibility, and Preliminary Impact of 4 Remotely-Delivered Interventions for Rural Older Adults Living with HIV.

People living with HIV (PLH) who live in rural areas of the United States (US) face more challenges to obtaining medical care and suffer higher mortality rates compared to non-rural PLH. Compared with younger PLH, older PLH (age 50+) also face additional challenges to maintaining their health and wellbeing. Despite the heightened barriers to receiving care and remaining adherent to treatment among older rural PLH, few interventions to increase viral suppression and improve quality of life exist for this population. We pilot-tested four remotely-delivered interventions-group-based social support, group-based stigma-reduction, individual strengths-based case management, and individual technology detailing-aimed to improve care engagement and quality of life in rural older PLH in the southern US. Participants (N = 61, Mage = 58, 75% male) completed surveys and self-collected blood specimens at baseline and 3 months; in between, they were randomized to 0-4 interventions. We assessed feasibility, acceptability, and preliminary impact on medication adherence, viral suppression, quality of life, depressive symptoms, and hypothesized mediating mechanisms. More than 80% participated in assigned intervention(s), and 84% completed the study. Interventions were highly acceptable to participants, with more than 80% reporting they would recommend interventions to peers. More than 80% found the social support and case management interventions to be relevant and enjoyable. We found promising preliminary impact of interventions on quality of life, medication adherence, depressive symptoms, internalized stigma, and loneliness. Remotely-delivered interventions targeting rural older PLH are feasible to conduct and acceptable to participants. Larger scale study of these interventions is warranted.

RESUMEN: A pesar de las múltiples barreras para la adherencia a la medicación y la recepción de atención entre las personas mayores de zonas rurales que viven con el VIH, existen pocas intervenciones para mejorar la supresión viral y la calidad de vida para esta población. Realizamos pruebas piloto de intervenciones realizadas de forma remota (grupos de apoyo social, grupos de reducción del estigma, manejo de casos basado en los puntos fuertes y "technology detailing") entre las personas que viven con el VIH en zonas rurales del sur de Estados Unidos. Los participantes (N = 61, Medad = 58, 75% hombres) completaron encuestas y recolectaron muestras de sangre al inicio y a los 3 meses; en el medio, fueron asignados al azar a 0­4 intervenciones. Evaluamos la viabilidad, la aceptabilidad y el impacto preliminar. Más del 80% participó en la(s) intervención(es) y el 84% completó el estudio. Las intervenciones fueron muy aceptables para los participantes; más del 80% consideró que las intervenciones de apoyo social y gestión de casos eran relevantes y agradables. Las intervenciones tuvieron un impacto preliminar prometedor sobre la calidad de vida, la adherencia a la medicación, los síntomas depresivos, el estigma y la soledad. Las intervenciones realizadas a distancia dirigidas a las personas que viven con el VIH en zonas rurales de edad avanzada son viables y aceptables, y se justifica un estudio a mayor escala.

The interrelationships between sleep regularity, obstructive sleep apnea, and hypertension in a middle-aged community population.

STUDY OBJECTIVES: Little is known about the interrelationships between sleep regularity, obstructive sleep apnea (OSA) and important health markers. This study examined whether irregular sleep is associated with OSA and hypertension, and if this modifies the known association between OSA and hypertension. METHODS: Six hundred and two adults (age mean(SD) = 56.96(5.51) years, female = 60%) from the Raine Study who were not evening or night shift workers were assessed for OSA (in-laboratory polysomnography; apnea-hypopnea index ≥ 15 events/hour), hypertension (doctor diagnosed, or systolic blood pressure ≥140 mmHg and/or diastolic ≥90 mmHg) and sleep (wrist actigraphy for ≥5 days). A sleep regularity index (SRI) was determined from actigraphy. Participants were categorized by tertiles as severely irregular, mildly irregular, or regular sleepers. Logistic regression models examined the interrelationships between SRI, OSA and hypertension. Covariates included age, sex, body mass index, actigraphy sleep duration, insomnia, depression, activity, alcohol, smoking, and antihypertensive medication. RESULTS: Compared to regular sleepers, participants with mildly irregular (OR 1.97, 95% confidence intervals [CI] 1.20 to 3.27) and severely irregular (OR 2.06, 95% CI: 1.25 to 3.42) sleep had greater odds of OSA. Compared to those with no OSA and regular sleep, OSA and severely irregular sleep combined had the highest odds of hypertension (OR 2.34 95% CI: 1.07 to 5.12; p for interaction = 0.02) while those with OSA and regular/mildly irregular sleep were not at increased risk (p for interaction = 0.20). CONCLUSIONS: Sleep irregularity may be an important modifiable target for hypertension among those with OSA.

Spatial variation in population genomic responses to over a century of anthropogenic change within a tidal marsh songbird.

Combating the current biodiversity crisis requires the accurate documentation of population responses to human-induced ecological change. However, our ability to pinpoint population responses to human activities is often limited to the analysis of populations studied well after the fact. Museum collections preserve a record of population responses to anthropogenic change that can provide critical baseline data on patterns of genetic diversity, connectivity, and population structure prior to the onset of human perturbation. Here, we leverage a spatially replicated time series of specimens to document population genomic responses to the destruction of nearly 90% of coastal habitats occupied by the Savannah sparrow (Passerculus sandwichensis) in California. We sequenced 219 sparrows collected from 1889 to 2017 across the state of California using an exome capture approach. Spatial-temporal analyses of genetic diversity found that the amount of habitat lost was not predictive of genetic diversity loss. Sparrow populations from southern California historically exhibited lower levels of genetic diversity and experienced the most significant temporal declines in genetic diversity. Despite experiencing the greatest levels of habitat loss, we found that genetic diversity in the San Francisco Bay area remained relatively high. This was potentially related to an observed increase in gene flow into the Bay Area from other populations. While gene flow may have minimized genetic diversity declines, we also found that immigration from inland freshwater-adapted populations into tidal marsh populations led to the erosion of divergence at loci associated with tidal marsh adaptation. Shifting patterns of gene flow through time in response to habitat loss may thus contribute to negative fitness consequences and outbreeding depression. Together, our results underscore the importance of tracing the genomic trajectories of multiple populations over time to address issues of fundamental conservation concern.
