Does sexual rehabilitation work for gay and bisexual prostate cancer patients? Acceptability, feasibility, and efficacy results from the Restore-2 randomized controlled trial.

PURPOSE: Sexual minority prostate cancer patients have worse health-related quality of life outcomes than heterosexual patients. We conducted the first study to test whether sexual and urinary rehabilitation tailored for sexual minority patients was acceptable, feasible, and efficacious at improving their sexual and urinary function. METHODS: Restore-2 was a 24-month randomized controlled trial of an online biopsychobehavioral rehabilitation study for sexual minority men treated for prostate cancer experiencing sexual and/or urinary problems. Participants were 401 US sexual minority men treated for prostate cancer and experiencing sexual and/or urinary problems at baseline. Intervention components included phosphodiesterase-5 inhibitors, sexual aids, a pelvic floor exercise regimen and video, a guide to good gay sex following treatment, and coaching. Quality of life assessments were completed at baseline, 3, 6, 12, 18, and 24 months. RESULTS: We confirmed good acceptability and feasibility, but only minimal improvement was observed over time and no differences were found between treatment and control arms. CONCLUSIONS: We found no evidence that the intervention improved sexual or urinary outcomes for participants. However, we confirmed excellent acceptability and feasibility for a sexual rehabilitation program tailored to sexual minority participants. In addition, participants reported enduring usage and acceptability of sexual aids (including vacuum pump, anal dilators, and penile constriction rings) as well as masturbation and pelvic floor exercises to accommodate their sexual challenges. IMPLICATIONS FOR CANCER SURVIVORS: Sexual "accommodation," rather than "rehabilitation," may be a more accurate and realistic goal for this population. Patients should be provided sexual aids to help accommodate their sexual and urinary challenges. TRIAL REGISTRATION: This study was retrospectively registered with ClinicalTrials.gov, study number: NCT03923582; date: 22/04/2019.

It Takes a Team-Enhancing Student-Athlete Health and Well-Being through an Interprofessional Approach.

Student-athlete well-being is a key objective for individuals working with or for university athletic departments. This paper will describe how a university athletic department used a team approach to enhancing student-athlete health and well-being. The Interprofessional Education Collaborative (IPEC) Core Competencies of (1) Values and Ethics; (2) Roles and Responsibilities; (3) Communication; and (4) Teams and Teamwork provide a guiding framework for interprofessional collaboration. (IPC; Interprofessional Education Collaborative, 2023). However, significant barriers exist in implementing IPC in university athletic departments and little research exists on how to overcome these barriers in university athletic departments to enhance student-athlete wellness. To address this gap, this paper will first provide a review of the literature on athlete well-being, followed by an applied section that describes the experience of an interprofessional wellness team (IWT) consisting of a clinical sports psychology doctoral student, a licensed mental health professional, an athletic trainer, and a sports dietitian. A case vignette is used to demonstrate how IPEC core competencies are operationalized by the team to address athlete health and well-being through IPC. Recommendations on the further implementation of IPC centered around student-athlete well-being will be provided.

Using Low-cost Videoscopes to Obtain Accurate Video "Oral Selfies" as Screening for HPV-associated Oropharyngeal Cancer: A New Screening Technology?

Human papillomavirus (HPV)-related oropharyngeal cancers associated with sexual contact are increasing, with high rates in men who have sex with men. HPV-related cancers have the advantage of being frequently detectable through oropharyngeal visual examination and having much higher survival rates than classic oropharyngeal cancers. It has been demonstrated that gay and bisexual men can take smartphone oropharyngeal "selfies" of sufficient quality for screening. However, there is an issue with the inability to move the tongue to allow a clear view of the palatine tonsils, where a majority of oropharyngeal cancer cases occur. We attempted to investigate the feasibility of using commercially available videoscopes to visualize the oropharynx. Fourteen healthy volunteers used a provided low-cost commercial endoscope to video their oropharynx. Participants used the videoscope connected to a laptop and could visualize the oropharynx on the screen. Attempts were observed, and the process was noted. A focus group of participants was carried out immediately afterwards to ascertain barriers and facilitators to using the videoscopes. All participants were able to use the videoscope and obtain videos of sufficient clarity to note major oropharyngeal landmarks. The palatine tonsils were initially difficult to visualize because the tongue could not be sufficiently controlled. Participants were given time to practice using visual cues to control the position of the tongue, which helped in obtaining good videos. Videoscopes can be used effectively with minimal instruction and provide a better view than still images, as they illuminate and magnify the site. Low-cost commercially available videoscopes may be an improvement over smartphone "selfies".

The benefits of a virtual emergency department observation unit for hospital observation patients.

BACKGROUND: The benefit of virtual emergency department observation unit (EDOU) care relative to traditional observation care in an inpatient bed is unknown. OBJECTIVE: To determine if virtual observation care in an EDOU is associated with improved length of stay, cost, inpatient admission rate, and adverse events relative to traditional observation care in non-observation unit (NOU) inpatient bed. METHODS: This is a retrospective observational cohort study of observation patients managed over 24 months in two urban teaching hospitals. Following an ED visit, observation care occurred in a virtual-EDOU or NOU inpatient setting based on bed availability, physician discretion, and observation guidelines. Primary outcomes were length of stay, total cost, inpatient admission rate, and adverse events (death or ICU admission). Hospital cost and clinical databases were used. Analysis with a doubly-robust regression with entropy balancing and propensity scores was used to control for subgroup differences. RESULTS: 30,191 observation patients were divided into 13,753 NOU patients and 16,438 EDOU patients with similar distributions for age and gender, and differences in health insurance and diagnosis. For both discharged and admitted patients, the mean cost was higher in the NOU setting at $7989 than the virtual-EDOU setting at $4876 with an adjusted difference of $1951 (95% CI: $1762-$2133). The mean total length of stay was higher in the NOU setting (60.5 h) than the virtual-EDOU setting (36.4 h) with an adjusted difference of 20.4 h (95% CI: 19.2 h - 21.3 h). NOU inpatient admission rates were higher (25.3% vs 18.4%). Cost and length of stays were lower in discharged observation patients, with differences favoring the virtual-EDOU group. Adverse events were higher in the NOU setting (2.1% vs 0.8%). 30-day ED recidivism did not differ significantly between NOU and virtual-EDOU study groups. The virtual-EDOU saved the two hospitals $16,036,913 and 6986 bed-days annually. CONCLUSION: Management of observation patients in a virtual-EDOU setting is superior to care in a traditional inpatient setting in terms of costs, length of stays, inpatient admission and adverse events rates.

The Impact of a High Sensitivity Troponin HEART Pathway Based Clinical Decision Protocol on Observation Visits.

BACKGROUND: Use of high-sensitivity troponin (hs-cTn) might lead to an increase in hospital observation visits due to higher number of abnormal troponin levels. STUDY OBJECTIVES: To determine the impact of incorporating hs-cTn into a chest pain clinical decision protocol (CDP) on observation visits in a large academic health system. METHODS: This is a retrospective observational cohort study of all chest pain observation patients in four hospitals in an academic health system over 24 months. All hospitals used the Beckman Coulter Unicel Dxi instrument, and all shared the same emergency department (ED) chest pain protocol, which used the HEART pathway and serial troponins and directed ED dispositions to either an observation stay, ED discharge, or inpatient admission. Outcomes studied before and after introduction of a hs-cTn protocol included daily chest pain observation census, cost, observation hours, and inpatient admit rate. Census was reported as the daily chest pain observation census and as a proportion of all observation visits. Data was retrieved from a health system data warehouse and a cost accounting program. RESULTS: There were 6,712 chest pain observation visits over 24-months, with 4,087 visits before and 2,634 visits after the hs-cTn protocol implementation. Comparison groups were similar in terms of age, gender, and type of insurance. There were 10.59 (95% CI: 10.24 - 10.95) daily chest pain observation visits before and 7.66 (95% CI: 7.34 - 7.97) visits after implementation, with a 28% (95% CI: 35% - 20%) decrease in the total daily census. As a portion of all observation visits, there was a 22% drop in the proportion that were observed for chest pain. The daily number of chest pain patients requiring inpatient admission was unchanged. The daily total direct cost for chest pain observation decreased with an effective daily cost savings of $4,313 USD (95% CI: $1,534 - $6,998). The total daily number of chest pain observation bed hours also decreased by 41.5 hours (95% CI 13.4 - 96.4 hr). CONCLUSION: Implementation of a hs-cTn chest pain protocol was associated with a significant decrease in the number and proportion of observation visits, a decrease in total daily cost and bed hours used, and no increase in inpatient admissions.

An Update on Viral Infection-Associated Collapsing Glomerulopathy.

The COVID-19 era has been a reminder to clinicians around the world of the important role that viral infections play in promoting glomerular disease. Several viral infections including human immunodeficiency virus (HIV), severe acute respiratory syndrome coronavirus 2, Epstein-Barr virus, cytomegalovirus, and parvovirus B19 can cause podocyte injury and present with a collapsing glomerulopathy (CG) variant of focal segmental glomerulosclerosis or minimal change disease. CG associated with COVID-19 has been termed COVID-19-associated nephropathy due to its striking resemblance to HIV-associated nephropathy. Host susceptibility is a major determinant of viral infection-associated CG, and the presence of two APOL1 risk variants explains most of the racial predilection to viral-associated CG observed in individuals of African ancestry. Interactions between APOL1 risk variants, viral genes, and the systemic inflammatory response to viral infection all contribute to kidney injury. This review will summarize our current knowledge of viral infection-associated CG, focusing primarily on the clinical presentation, histological features, mechanisms, and disease course of HIV-associated nephropathy and COVID-19-associated nephropathy.

Healthcare professional students' skills in sexual health communication and history taking: inter-rater reliability of standardized patients and faculty ratings in dar es Salaam, tanzania- a cross-sectional study.

BACKGROUND: Low- and middle-income countries face a disproportionate impact of sexual health problems compared to high-income countries. To address this situation proper interpersonal communication skills are essential for clinician to gather necessary information during medical history-taking related to sexual health. This study aimed to evaluate the interrater reliability of ratings on sexual health-related interpersonal communication and medical history-taking between SPs and trained HCP faculty for health care professional students. METHODS: We conducted a cross-sectional comparative study to evaluate the interrater reliability of ratings for sexual health-related interpersonal communication and medical history-taking. The data were collected from medical and nursing students at Muhimbili University of Health and Allied Sciences, who interviewed 12 Standardized Patients (SPs) presenting with sexual health issues. The video-recorded interviews rated by SPs, were compared to the one rated by 5 trained Health Care Professional (HCP) faculty members. Inter-rater reliability was evaluated using percent agreement (PA) and kappa statistics (κ). RESULTS: A total of 412 students (mean age 24) were enrolled in the study to conduct interviews with two SPs presenting with sexual health concerns. For interpersonal communication (IC), the overall median agreement between raters was slight (κ2 0.0095; PA 48.9%) while the overall median agreement for medical sexual history-taking was deemed fair (κ2 0.139; PA 75.02%). CONCLUSION: The use of SPs for training and evaluating medical and nursing students in Tanzania is feasible only if they undergo proper training and have sufficient time for practice sessions, along with providing feedback to the students.

Universal pH electrocatalytic hydrogen evolution with Au-based high entropy alloys.

The creation of electrocatalysts with reduced concentrations of platinum-group metals remains a critical challenge for electrochemical hydrogen production. High-entropy alloys (HEAs) offer a distinct type of catalyst with tunable compositions and engineered surface activity, significantly enhancing the hydrogen evolution reaction (HER). We present the synthesis of AuPdFeNiCo HEA nanoparticles (NPs) using a wet impregnation method. The composition and structure of the AuPdFeNiCo HEA NPs are characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and high-resolution transmission electron microscopy (HR-TEM). These nanoparticles exhibit robust HER performance quantified over a broad pH range, with higher activity than any of the unary metal counterparts in all pHs. In comparison to a commercial 10%Pt/C electrocatalyst, AuPdFeNiCo HEA NPs exhibit enhanced electrochemical activity in both acidic and alkaline electrolytes at a current density of 10 mA cm-2. Additionally, these nanoparticles achieve a current density of 100 mA cm-2 at a voltage of 540 mV in neutral electrolytes, outperforming Pt/C which requires 570 mV. These findings help enable broad use of reduced precious metal electrocatalysts for water electrolysis in a variety of water and pH conditions.

The need for and acceptability of a cancer training course for medical and nursing students in Tanzania: a convergent mixed methods study.

BACKGROUND: The cancer burden in Africa is on the rise. A Cancer Training Course on screening, prevention, care, and community education is crucial for addressing a wide range of cancer health issues. When appropriately educated healthcare providers on cancer provide care, patient care improves, and healthcare costs decrease. However, in Tanzania, doctors and nurses receive little or no training in primary cancer care in their bachelor's program. AIM: This study assessed the need and acceptability of a cancer training course for nursing and medical doctor students at the Muhimbili University of Health and Allied Sciences (MUHAS) in Dar es Salaam, Tanzania. METHODS: This study was a cross-sectional parallel mixed method study during the 3-month follow-up within the larger study on sexual health training for health professionals. The study was a randomized controlled (RCT), single-blind, parallel trial of sexual health training versus a waitlist control among health students at MUHAS in Tanzania. Descriptive analysis was performed to analyze the participants' demographic information, need, and acceptability of the cancer training courseto determine the frequencies and percentages of their distribution between disciplines. In addition, inductive thematic analysis was performed for the qualitative data. The RCT study was registered at Clinical Trial.gov (NCT03923582; 01/05/2021). RESULTS: Data were collected from 408 students (272 medical doctors and 136 nursing students). The median age of the participants was 23 years. Most (86.0%) medical and 78.1% of nursing students reported receiving little to no cancer training. On the other hand, most (92.3%) medical and nursing (92.0%) students were interested in receiving cancer training. Furthermore, 94.1% of medical and 92.0% of nursing students needed a cancer training course in their undergraduate program. In addition, participants said a cancer training course would be important because it would help them improve the quality of cancer care and enhance the quality of life for patients by ensuring early diagnosis and treatment. CONCLUSION: A cancer training course is both highly needed and acceptable to medical and nursing students. Implementation of this cancer training course will improve students' knowledge and skills and eventually improve the quality of cancer care and patients' quality of life by ensuring early diagnosis and management.

Long-term impact of immediate versus deferred antiretroviral therapy on kidney health in people with HIV.

People with human immunodeficiency virus (HIV) are at risk for chronic kidney disease (CKD) due to HIV and antiretroviral therapy (ART) nephrotoxicity. Immediate ART initiation reduces mortality and is now the standard of care, but the long-term impact of prolonged ART exposure on CKD is unknown. To evaluate this, the Strategic Timing of Antiretroviral Treatment (START) trial randomized 4,684 ART-naïve adults with CD4 cell count under 500 cells/mm3 to immediate versus deferred ART. We previously reported a small but statistically significantly greater decline in estimated glomerular filtration rate (eGFR) over a median of 2.1 years in participants randomized to deferred versus immediate ART. Here, we compare the incidence of CKD events and changes in eGFR and urine albumin/creatinine ratio (UACR) in participants randomized to immediate versus deferred ART during extended follow-up. Over a median of 9.3 years, eight participants experienced kidney failure or kidney-related death, three in the immediate and five in the deferred ART arms, respectively. Over a median of five years of more comprehensive follow-up, the annual rate of eGFR decline was 1.19 mL/min/1.73m2/year, with no significant difference between treatment arms (difference deferred - immediate arm 0.055; 95% confidence interval -0.106, 0.217 mL/min/1.73m2). Results were similar in models adjusted for baseline covariates associated with CKD, including UACR and APOL1 genotype. Similarly, there was no significant difference between treatment arms in incidence of confirmed UACR 30 mg/g or more (odds ratio 1.13; 95% confidence interval 0.85, 1.51). Thus, our findings provide the most definitive evidence to date in support of the long-term safety of early ART with respect to kidney health.

Reliability of a Musculoskeletal Imaging Competency Examination for Physical Therapists.

INTRODUCTION: The Burley Readiness Examination (BRE) for Musculoskeletal (MSK) Imaging Competency assesses physical therapists' baseline MSK imaging competency. Establishing its reliability is essential to its value in determining MSK imaging competency. The purpose of this study was to test the reliability of the BRE for MSK Imaging Competency among physical therapists (PTs) with varying levels of training and education. REVIEW OF LITERATURE: Previous literature supports PTs' utility concerning diagnostic imaging; however, no studies directly measure their competency. With PTs expanding their practice scope and professional PT education programs, increasing their MSK imaging instruction, assessing competency becomes strategic in determining the future of MSK education and training. SUBJECTS: One hundred twenty-three United States licensed PTs completed the BRE. METHODS: Physical therapists completed the BRE through an online survey platform. Point biserial correlation (rpb) was calculated for each examination question. Final analyses were based on 140 examination questions. Examination scores were compared using independent sample t-test and one-way analysis of variance. Chi-square tests and odds ratios (ORs) assessed the relationship of a passing examination score (≥75%) and the type of training. Reliability of the BRE was assessed using Cronbach's alpha (α). RESULTS: Mean overall examination score was 75.89 ± 8.56%. Seventy PTs (56.9%) obtained a passing score. Physical therapists with additional MSK imaging training, board certification, and residency or fellowship training scored significantly higher (P < .001) compared with those with only entry-level PT program education. Physical therapists with additional MSK imaging training scored significantly higher (x̄ = 81.07% ± 8.93%) and were almost 5 times (OR = 4.74, 95% CI [1.95-11.50]) as likely to achieve a passing score than those without. The BRE demonstrated strong internal consistency (Cronbach's α = 0.874). DISCUSSION AND CONCLUSIONS: The BRE was reliable, consistently identifying higher examination scores among those with increased MSK imaging training. Training in MSK imaging influenced competency more than other factors. The BRE may be of analytical value to PT professional and postprofessional programs.

Aqueous Synthesis of Plasmonic Gold-Tin Alloy Nanoparticles.

This protocol describes the synthesis of Au nanoparticle seeds and the subsequent formation of Au-Sn bimetallic nanoparticles. These nanoparticles have potential applications in catalysis, optoelectronics, imaging, and drug delivery. Previously, methods for producing alloy nanoparticles have been time-consuming, require complex reaction conditions, and can have inconsistent results. The outlined protocol first describes the synthesis of approximately 13 nm Au nanoparticle seeds using the Turkevich method. The protocol next describes the reduction of Sn and its incorporation into the Au seeds to generate Au-Sn alloy nanoparticles. The optical and structural characterization of these nanoparticles is described. Optically, prominent localized surface plasmon resonances (LSPRs) are apparent using UV-visible spectroscopy. Structurally, powder X-ray diffraction (XRD) reflects all particles to be less than 20 nm and shows patterns for Au, Sn, and multiple Au-Sn intermetallic phases. Spherical morphology and size distribution are obtained from transmission electron microscopy (TEM) imaging. TEM reveals that after Sn incorporation, the nanoparticles grow to approximately 15 nm in diameter.

The feasibility of emergency department observation units in the management of mild to moderate hyponatremia.

OBJECTIVE: To describe the feasibility of managing hyponatremia patients under outpatient observation status in an academic medical center, and compare outcomes based on the use of an emergency department observation unit (EDOU). METHODS: This is a retrospective cohort study of emergency department hyponatremic patients managed in four hospitals within a large urban academic medical center over 27 months. All patients had an admit-to-observation order, ICD-10 codes for hyponatremia, and mild (130-135 mmol/L) to moderate (121-129 mmol/L) hyponatremia. Observation settings were divided into two groups: EDOU and Non-Observation Unit (NOU) inpatient beds. Severe hyponatremia (≤120 mmol/L) was excluded. Primary clinical outcomes were inpatient admit rate, length of stay (LOS), total direct cost, the rate of adverse events and 30-day recidivism. RESULTS: 188 patients were managed as an observation patient, with 64 managed in an EDOU setting (age 74.0 yr, 70.3% female) and 124 managed in a NOU setting (age 71.5 yr, 64.5% female). Patient subgroups were similar in terms of presenting complaints, comorbidities, and medication histories. Initial and final sodium levels were similar between settings: EDOU (125.1 to 132.6 mmol/L) vs NOU (123.5 to 132.0 mmol/L). However, outcomes differed by setting for observation to inpatient admit rate (EDOU 28.1% vs NOU 37.9%, adjusted effect 0.70), overall length of stay (EDOU 19.2 h vs NOU 31.9 h; adjusted effect -10.5 h and total direct cost ($1230 vs $1531; adjusted effect -$167). EDOU sodium correction rates were faster (EDOU 0.44 mmol/L/h vs 0.24 mmol/L/h; adjusted effect 0.15 mmol/L/h) and 30-day recidivism rate was similar (EDOU 13% vs NOU 15%). There were no index visit deaths or intensive care unit admissions. CONCLUSION: Management of selected hyponatremia patients under observation status is feasible, with the EDOU setting demonstrating lower admit rates, shorter length of stay, and lower total direct costs with similar clinical outcomes.

The need for and acceptability of a curriculum to train nursing and medical students in the sexual healthcare of clients with female genital mutilation/cutting in Tanzania.

BACKGROUND: Female genital mutilation/cutting (FGM/C) is tied to one of the most conservative cultures in the Mediterranean and Sub-Saharan Africa. More than 200 million girls and women in 30 African, Asian and the middle Eastern countries have undergone FGM/C. However, healthcare professionals are not adequately trained to prevent and manage FGM/C-related complications including sexual health problems. This study aimed to assess the need and acceptability of a curriculum to train nursing and medical students in the sexual healthcare of clients with FGM/C in Tanzania. METHODS: We used a descriptive and cross sectional study design to collect and analyse information from 271 medical and 137 nursing students in Tanzania. A Qualtrics online survey was used to obtain quantitative data on training interest, previous training received, and the curriculum delivery method. Open-ended questions were used to explore their insights on significance to obtain the necessary competencies to treat and prevent FGM/C. Descriptive statistics were used to analyze quantitative data while qualitative data were analyzed using a thematic approach. RESULTS: Almost half of the participants reported they had little to no training in sexual healthcare for women with FGM/C (47%). In all, 82.4% reported the training to be acceptable. Following thematic analysis of open-ended questions, participants expressed a desire to improve their competencies to meet the current and future sexual and psychological health needs of women and girls who have undergone FGM/C. CONCLUSION: It is a necessary and acceptable to develop a curriculum to train healthcare students to diagnose, treat and prevent sexual health complications related to FGM/C. In our study, designing a culturally sensitive curriculum and its delivery method, that includes practical sessions with simulated patients, was considered the most beneficial and favorable.

Progress towards a targeted biorefinery of Chromochloris zofingiensis: a review.

Biorefinery approaches offer the potential to improve the economics of the microalgae industry by producing multiple products from a single source of biomass. Chromochloris zofingiensis shows great promise for biorefinery due to high biomass productivity and a diverse range of products including secondary carotenoids, predominantly astaxanthin; lipids such as TAGs; carbohydrates including starch; and proteins and essential amino acids. Whilst this species has been demonstrated to accumulate multiple products, the development of an integrated downstream process to obtain these is lacking. The objective of this review paper is to assess the research that has taken place and to identify the steps that must be taken to establish a biorefinery approach for C. zofingiensis. In particular, the reasons why C. zofingiensis is a promising species to target for biorefinery are discussed in terms of cellular structure, potential products, and means to accumulate desirable components via the alteration of culture conditions. Future advances and the challenges that lie ahead for successful biorefinery of this species are also reviewed along with potential solutions to address them.

Sexual Behavior and Perceived Risk for Oropharyngeal Cancer Among Men Who Have Sex With Men: A Psychometric Scale Validation.

BACKGROUND: Men who have sex with men (MSM) are at increased risk for human papillomavirus-associated oropharyngeal cancer (HPV-OPC). The objective of this analysis was to create a psychometrically validated scale to measure perception of risk for HPV-OPC. METHODS: We conducted an exploratory and a confirmatory factor analysis to determine and confirm the latent factor structure. We used a path diagram to evaluate the relationship between the validated scale and perceived risk for HPV-OPC. The model was determined to be a good fit if it met all criteria: root mean square error of approximation ≤0.06, standardized root mean residual ≤0.08, Comparative Fit Index ≥0.90, and Tucker-Lewis Index ≥0.90. We report standardized estimates and 95% confidence intervals. RESULTS: This cross-sectional study recruited 1315 MSM. A majority (73.33%) of MSM had performed fellatio on ≥20 partners, 36.98% had rimmed ≥20 partners, and 5.31% had performed cunnilingus on ≥10 partners in their lifetime.Six sexual history survey items loaded onto 2 latent factors: sexual risk behaviors: class 1 and sexual risk behaviors: class 2. The final model statistics indicated good fit: root mean square error of approximation = 0.064, standardized root mean residual = 0.059, Comparative Fit Index = 0.996, and Tucker-Lewis Index = 0.993. Sexual risk behaviors: class 1 was associated with greater perceived risk for HPV-OPC (0.217; 95% confidence interval, 0.138-0.295). Age, HIV status, HPV vaccination status, and sexual risk behaviors: class 2 were not associated with perceived risk for HPV-OPC. CONCLUSION: Men who have sex with men assessed risk for HPV-OPC based on their lifetime number of cisgender male sexual partners, rimming partners, and fellatio partners but not other sexual behaviors. Men who have sex with men may be responsive to future HPV-OPC educational interventions and opportunities for screening.

Breastfeeding moderates the association of maternal pre-pregnancy nutritional status with offspring body composition at 30 years.

Maternal pre-pregnancy body mass index is positively associated with offspring obesity, even at adulthood, whereas breastfeeding decreases the risk of obesity. The present study was aimed at assessing whether breastfeeding moderates the association of maternal pre-pregnancy body mass index with offspring body composition at adulthood, using data from 3439 subjects enrolled in a southern Brazilian birth cohort. At 30 years of age, maternal pre-pregnancy body mass index was positively associated with offspring prevalence of obesity, abdominal obesity, as well as body mass index and fat and lean mass index. Breastfeeding moderated the association of maternal pre-pregnancy obesity with offspring adiposity at 30 years of age. For those breastfed<6 months, body mass index was 4.13 kg/m2 (95% confidence interval: 2.98; 5.28) higher among offspring of obese mothers, in relation to offspring of normal weight mothers, whereas among those breastfed≥6 months the magnitude of the difference was small [2.95 kg/m2 (95% confidence interval: 1.17; 4.73)], p-value for interaction = 0.03. Concerning obesity, among those who had been breastfed < 6 months, the prevalence of obesity was 2.56 (95% confidence interval: 1.98; 3.31) times higher among offspring of obese mothers. On the other hand, among those who were breastfed ≥ 6 months, the prevalence of obesity was 1.82 (95% confidence interval: 1.09; 3.04) times higher among offspring of obese mothers. Therefore, among overweight mothers breastfeeding for more than 6 months should be supported, as it may mitigate the consequences of maternal overweight on offspring body composition.

Association of same-sex criminalisation laws and national HIV policies with HIV testing in African MSM: an ecological single-level and multilevel cross-sectional study of sub-Saharan African countries.

BACKGROUND: HIV incidence among men who have sex with men (MSM) in sub-Saharan Africa (SSA) remains high compared with the general population. Many countries in the region still criminalise consensual homosexual relationships, and some are yet to adopt WHO-recommended interventions for MSM into national HIV policies. This study examines how HIV testing of adult MSM in SSA varies according to the legal climate and presence of targeted HIV policy using data from the cross-sectional 2019 Global LGBTI Internet Survey study. METHODS: Using data from 3191 MSM in 44 SSA countries, we assessed associations of legal climate and HIV policy with ever and recent HIV testing using linear ecological and logistic multilevel analyses. From the single-level analysis, we can compare our findings to previously reported data, then, extending to a two-level multilevel analysis, we account for the hierarchical structure of the population and simultaneously adjust for differences in context and composition in each country. We then test the sensitivity of our analyses to excluding countries from the model. RESULTS: We find evidence that legalised same-sex relationships were associated with increased odds of ever testing (OR=2.00, 95% CI 1.04, 3.82) in multilevel analyses. We also find evidence of an association of targeted HIV policies with increased odds of ever testing (OR=2.49, 95% CI 1.12, 5.52). We did not find evidence of an association of the legal climate (OR=1.01, 95% CI 0.69, 1.46) and targeted HIV policies (OR=1.26, 95% CI 0.78, 2.04) with recent testing. CONCLUSIONS: This study suggests elimination of discriminatory laws and policies might be important for increasing HIV status awareness of MSM, an important first step in epidemic control. Additionally, we highlight heterogeneity between South Africa and other SSA countries, which has implications for studying SSA countries as a homogeneous group.

Factors associated with decreased anal sphincter tone and the accuracy of forced anal examinations to detect individuals having receptive anal intercourse: An observational study.

Objective and Design: Forced anal examinations are used to prosecute sexual and gender minorities (SGM) in at least seven countries under the presumption that decreased sphincter tone, estimated by a finger inserted into the anal canal, can detect persons practicing receptive anal intercourse. In a cross-sectional analysis of the baseline data from a longitudinal study, we aimed to determine factors associated with sphincter tone and the accuracy of sphincter tonality to detect persons engaging in receptive anal intercourse. Setting: Clinicians in Chicago, Houston, and Milwaukee, USA conducted digital anal rectal examinations (DARE) on 838 participants, 94.0% of whom were cisgendered males. Clinicians used the Digital Rectal Examination Scoring System to score sphincter resting tone (RT) and squeeze tone (ST). On a separate survey, individuals reported their preferred position for anal intercourse: i.e., either always/mostly insertive anal intercourse, always/mostly receptive anal intercourse, or both receptive and insertive anal intercourse. Multivariable regression assessed factors associated with decreased sphincter tone while area under the Receiver Operating Characteristic curves (AUC) estimated the accuracy of sphincter tonality to detect receptive anal intercourse. Results: 11.3% had decreased RT (95/838) and 6.3% had decreased ST (53/838). The accuracy of DARE to detect any receptive anal intercourse was little better than random guessing (AUC 0.53, 95% CI 0.51 to 0.55, and AUC 0.51, 95% CI 0.49 to 0.53, respectively. RT and ST decreased with age regardless of sexual behavior (p trend <0.01 for both). Compared to individuals having always/mostly insertive anal intercourse, individuals having always/mostly receptive anal intercourse was associated with decreased RT, but not ST, while those equally preferring both insertive and receptive anal intercourse were not associated with decreased RT or ST. Conclusions: Decreased sphincter tone is uncommon among SGM who prefer receptive anal intercourse. Given virtually no accuracy, a finger inserted into the anus has no utility to detect individuals practicing receptive anal intercourse and thus should not be used as such. Trial registration: NCT04090060. Summary Box: What is already known on this topic: To gather evidence for prosecution of sexual and gender minorities, forced anal exams are used in multiple countries. The examination includes inserting the index finger into the anal canal to detect decreased sphincter tone which is considered evidence of receptive anal intercourse. We found only two small studies (n= 58 and n=24) assessing factors associated with decreased sphincter tone and none assessing the accuracy of sphincter tone to detect sexual and gender minorities having receptive anal intercourse.What this study adds: Our study suggests that a finger inserted into the anal canal is not useful to detect a history of receptive anal intercourse. As such, the sexual practices of individuals cannot be known using a forced anal examination.

Sex-Dependent Variations in Hypothalamic Fatty Acid Profile and Neuropeptides in Offspring Exposed to Maternal Obesity and High-Fat Diet.

Maternal obesity and/or high-fat diet (HF) consumption can disrupt appetite regulation in their offspring, contributing to transgenerational obesity and metabolic diseases. As fatty acids (FAs) play a role in appetite regulation, we investigated the maternal and fetal levels of FAs as potential contributors to programmed hyperphagia observed in the offspring of obese dams. Female mice were fed either a control diet (CT) or HF prior to mating, and fetal and maternal blood and tissues were collected at 19 days of gestation. Elevated levels of linoleic acid were observed in the serum of HF dams as well as in the serum of their fetuses. An increased concentration of eicosadienoic acid was also detected in the hypothalamus of female HF-O fetuses. HF-O male fetuses showed increased hypothalamic neuropeptide Y (Npy) gene expression, while HF-O female fetuses showed decreased hypothalamic pro-opiomelanocortin (POMC) protein content. Both male and female fetuses exhibited reduced hypothalamic neurogenin 3 (NGN-3) gene expression. In vitro experiments confirmed that LA contributed to the decreased gene expression of Pomc and Ngn-3 in neuronal cells. During lactation, HF female offspring consumed more milk and had a higher body weight compared to CT. In summary, this study demonstrated that exposure to HF prior to and during gestation alters the FA composition in maternal serum and fetal serum and hypothalamus, particularly increasing n-6, which may play a role in the switch from POMC to NPY neurons, leading to increased weight gain in the offspring during lactation.
