Socioeconomic representativeness of Australian, Canadian and British cohorts from the paediatric diabetes AdDIT study: comparisons to regional and national data.

BACKGROUND: Given limited data regarding the involvement of disadvantaged groups in paediatric diabetes clinical trials, this study aimed to evaluate the socioeconomic representativeness of participants recruited into a multinational clinical trial in relation to regional and national type 1 diabetes reference populations. METHODS: Retrospective, cross-sectional evaluation of a subset of adolescent type 1 diabetes cardiorenal intervention trial (AdDIT) participants from Australia (n = 144), Canada (n = 312) and the UK (n = 173). Validated national measures of deprivation were used: the Index of Relative Socioeconomic Disadvantage (IRSD) 2016 (Australia), the Material Resources (MR) dimension of the Canadian Marginalisation index 2016 (Canada) and the Index of Multiple Deprivation (IMD) 2015 (UK). Representativeness was assessed by comparing the AdDIT cohort's distribution of deprivation quintiles with that of the local paediatric type 1 diabetes population (regional), and the broader type 1 diabetes population for which the trial's intervention was targeted (national). RESULTS: Recruited study cohorts from each country had higher proportions of participants with higher SES, and significant underrepresentation of lower SES, in relation to their national references. The socioeconomic make-up in Australia mirrored that of the regional population (p = 0.99). For Canada, the 2nd least deprived (p = 0.001) and the most deprived quintiles (p < 0.001) were over- and under-represented relative to the regional reference, while the UK featured higher regional and national SES bias with over-representation and under-representation from the least-deprived and most-deprived quintiles (p < 0.0001). CONCLUSIONS: Significant national differences in trial participation of low SES participants were observed, highlighting limitations in access to clinical research and the importance of reporting sociodemographic representation in diabetes clinical trials.

The differential prognostic implications of PD-L1 expression in the outcomes of Filipinos with EGFR-mutant NSCLC treated with tyrosine kinase inhibitors.

Background: The tumor immune microenvironment influences tumor evolution in non-small cell lung cancer (NSCLC). Yet, the prognostic value of programmed death-ligand 1 (PD-L1) in epidermal growth factor receptor (EGFR)-mutant NSCLC remains controversial. Additionally, prognostic studies in Filipinos with EGFR-mutant NSCLC remain unexplored to this day. Methods: We prospectively studied the outcomes of EGFR-mutant NSCLC in Filipino cohort, and retrospectively verified the survival trend using The Cancer Genome Atlas (TCGA) cohort. Kaplan-Meier method and generalized linear regression were used to assess survival. Expression and DNA methylation of cluster of differentiation 274 (CD274, gene that codes for PD-L1) were examined from TCGA tumor profiles. Pearson's correlation was used to correlate PD-L1 expression with outcomes associated with occurrence of EGFR mutations, tyrosine kinase inhibitor (TKI) types, and programmed cell death protein 1 (PD-1) expression. Proteome network analysis was used to examine the correlation between drug resistance and PD-L1. Results: PD-L1 positivity was associated with significantly longer progression-free survival (PFS; P=0.0096) but had a significantly contrasting influence in the overall survival (OS; P=0.0011). PD-L1 positivity (in both protein and RNA) was associated with longer median OS (mOS) in exon21 L858R, whereas, negativity was associated with longer mOS in exon19 deletion (exon19del). Stratification (high, low, negative) of PD-L1 expression lacked significant prognostic value (all P>0.05). PD-L1/CD274 expression (P<0.05) and DNA methylation (P<0.001) vary significantly among NSCLC subtypes and in different disease stages. Erlotinib treatment produced the longest median progression-free survival (mPFS; 874 days) relative to other EGFR-TKIs (137-311 days). PD-L1 lacked a significant correlation with EGFR-TKIs. Consistent with the immune-regulation activities of PD-1, higher expression leads to relatively shorter mOS. PD-1 correlated positively with PD-L1 expression and occurrence of exon21 L858R. Conclusions: PD-L1 differentially influenced the outcomes of Filipinos with EGFR-mutant NSCLC. NSCLC subtypes, disease stage, and PD-1 expression may impact the collective outcomes associated with PD-L1 and EGFR-sensitizing mutations.

Exploring thermal isomerisation in gas chromatography analyses using natural pyrethrins: Comparison of comprehensive two-dimensional and one-dimensional gas chromatography.

This study aims to assess and qualitatively compare the visual presentation of chromatographic data from the isomerisation of natural pyrethrins - a group of pesticides derived from Chrysanthemum flowers - using one-dimensional gas chromatography (1DGC) and comprehensive two-dimensional gas chromatography (GC×GC). Molecular structural changes, such as thermal isomerisation in this case, occur during gas chromatography injection and separation, to provide characteristic patterns which may not be routinely recognised on the 1D chromatogram. To demonstrate the influence of analytical method parameters on isomerisation processes, variations in oven temperature (isothermal vs. temperature programmed analysis), inlet mode (split vs. splitless), inlet temperature, and carrier gas flow rate were investigated. Increasing oven temperature was the most significant factor affecting isomerisation. Splitless injection mode and increasing inlet temperature promoted isopyrethrin formation, while the effect of inlet temperature appeared minimal with a split injection technique, most likely due to the short residence time in the inlet. Increased carrier gas flow rates in a temperature programmed analysis reduced retention time and minimised isomerisation. The unique presentation of isopyrethrin peaks on a GC×GC contour plot allows for facile recognition of isomerisation especially at low concentrations, simplifies chromatogram interpretation, and aids in analyte identification. It also confirms that the isomerisation process is irreversible since the pyrethrin I and II compounds are absent throughout the bridge formation. These benefits support the use of GC×GC over 1DGC to study isomerisation. Additionally, due to limited data in the literature, Kováts retention indices and linear retention indices of the natural pyrethrins, including isopyrethrins, were experimentally determined on four columns: DB-5 ms UI, Rxi-17Sil MS, SLB-IL60i, and SLB-IL111i.

Sexual and Gender Minority Men's Bystander Behaviors and Barriers in Response to Witnessing Minor Sexual Aggression.

Objective: Sexual and gender minority (SGM) men experience sexual assault victimization. Encouraging people to become involved when they witness high-risk sexual situations as a prosocial bystander is one preventative mechanism to address sexual assault victimization. However, research assessing the extent that SGM men will intervene when they witness a concerning male-to-male sexual situation and barriers that prevent intervention is lacking. We sought to address these gaps. Method: SGM men (n = 323, Mage = 39.4, range 18-77) completed a web-administered survey. Participants were asked if they had witnessed a high-risk sexual situation and, if so, to describe how they intervened; if they did not intervene, they were asked to explain why not. Data were analyzed using thematic analysis. Results: Nearly 50% (n = 157) of participants reported witnessing a situation that may require intervention, of those men 40% reported involvement. When SGM men intervened, their behaviors included direct and indirect verbal and nonverbal strategies. Reasons for not intervening included not appraising the situation as risky, not viewing it as their responsibility to intervene, or lacking the self-efficacy to act. Conclusion: SGM men reported similar barriers to intervention that heterosexual young adults encounter. Participants also provided a variety of intervention tactics that could be included in bystander intervention initiatives to increase their effectiveness and inclusivity. Additional efforts are needed to modify intervention initiatives at both the individual and community level.

Exploring preferences and decision-making about long-acting injectable HIV pre-exposure prophylaxis (PrEP) among young sexual minority men 17-24 years old.

Intramuscular cabotegravir for long-acting injectable HIV pre-exposure prophylaxis (i.e., LAI-PrEP) was approved by the U.S. FDA in 2021. We sought to explore LAI-PrEP decision-making among a nationwide sample of young sexual minority men (YSMM) 17-24 years old. In 2020, HIV-negative/unknown YSMM (n = 41) who met CDC criteria for PrEP were recruited online to participate in synchronous online focus groups eliciting preferences and opinions about LAI-PrEP, as well as the impact of a potential self-administered option. Data were analyzed using inductive and deductive thematic analysis with constant comparison. Preferences and decision-making about LAI-PrEP varied widely among YSMM, with participants frequently comparing LAI-PrEP to oral PrEP regimens. We identified five key themes related to LAI-PrEP decision-making including concerns about adherence to PrEP dosing and clinic appointments, awareness and knowledge of PrEP safety and efficacy data, comfort with needles, minimizing PrEP stigma, and considerations of self-administration. YSMM acknowledged more PrEP options as beneficial to supporting uptake and persistence.

Establishing Methods of Defect Closure in Roux-en-Y Gastric Bypass: an International Survey.

INTRODUCTION: Internal herniation (IH) can be a life-threatening complication of Roux-en-Y gastric bypass (RYGB). Randomised controlled trials support the routine closure of mesenteric spaces at RYGB. However, there is currently no consensus on the method of closure in clinical practice. The purpose of this survey is to understand bariatric surgeons' practice in this regard. METHODS: We conducted an international survey, whereby questions were created through collaboration of a consensus group of bariatric surgeons and hosted on the SurveyMonkey platform. The survey was distributed among British Obesity and Metabolic Surgery Society (BOMSS) members and international professional channels including The Upper Gastrointestinal Society (TUGS) and social media. RESULTS: One hundred and thirty-six surgeons from 34 countries completed the survey. Of these, 49 respondents were UK-based surgeons with a cumulative experience of approximately 2500 RYGB per annum. Forty-five (91.8%) respondents reported always closing mesenteric defects, of whom 57.8% elected to use non-absorbable non-barbed sutures, followed by staples/clips in 28.9% and a selection of other methods. Most respondents used more than one method. A total of 2 UK and 14 non-UK participants reported never closing mesenteric spaces. CONCLUSIONS: This survey has shown heterogeneity among defect closure and no consensus on preferred type. Additionally, there remains a practice of non-closure of mesenteric defects. We hope these findings help to inform further needed research and consensus building among experts.

Factors associated with quality of life, depressive symptoms, and perceived stress among rural older adults living with HIV in the United States.

PURPOSE: Rural older people living with HIV (PLH) in the United States are a population of growing size and significance. A better understanding of factors associated with quality of life (QOL), depressive symptoms, and stress in this population-especially modifiable factors-could inform future interventions. METHODS: Online or on paper, we surveyed 446 PLH aged 50+ residing in rural counties across the United States (Mage = 56, 67% male, 67% White, and 23% Black). Associations between social support, HIV stigma, satisfaction with medical care, discrimination in health care settings, and structural barriers and health-related QOL, depressive symptoms, and perceived stress were assessed using multiple linear regressions. FINDINGS: Controlling for demographics, greater social support was associated with better QOL, fewer depressive symptoms, and less stress. Greater HIV stigma was associated with more depressive symptoms and stress. Satisfaction with care was associated with better QOL and less stress. Discrimination in medical settings was associated with lower QOL and more depressive symptoms and stress. Finally, experiencing more structural barriers was associated with lower QOL and more depressive symptoms and stress. CONCLUSIONS: In addition to engagement in care and viral suppression, QOL and mental health are also critical considerations for rural older PLH. Increasing social support, reducing or providing skills to cope with HIV stigma, improving quality of care, reducing discrimination and stigma in medical settings, and reducing or mitigating the impact of structural barriers present potential targets for interventions aiming to improve the well-being of older rural PLH.

Exposure to family planning messages and teenage pregnancy: results from the 2017 Philippine National Demographic and Health Survey.

BACKGROUND: Teenage pregnancy is known to have physical, emotional, and psychosocial effects. Because of these risks, family planning and contraception messages have been disseminated in various forms of media, but their association with teenage pregnancy has not been studied previously in the Philippines. This study aims to examine the association between exposure to various family planning and contraception messages disseminated in various media channels and pregnancy among Filipino women aged 15-19. The study also intended to examine interactions between the different media channels where these family planning and contraception messages are being disseminated on their effect on teenage pregnancy. METHODS: We used data from the individual recode of the 2017 Philippine National Demographic and Health Survey. We used logistic regression for survey data to  study the association between exposure to family planning and contraception messages and teenage pregnancy. RESULTS: Out of 5120 respondents, 44% of respondents have accessed information on contraception from the internet, 25% have heard information about contraception through the radio, 55% of respondents have heard about contraception via television, 15% have read about contraception in the newspapers and magazines, and only 6% have received information on contraception via short messaging service (SMS). There were 420 (8.56%) who have ever been pregnant. After adjusting for confounding variables, those who were exposed to family planning/contraceptive messages via the internet (aOR: 0.90; 95% CI: 0.59, 1.35) and newspapers/magazines (aOR: 0.78; 95% CI: 0.44, 1.41) have lower odds of teenage pregnancy, but no strong evidence of their effectiveness. On the other hand, exposure to family planning messages through the radio (aOR: 1.06; 95% CI: 0.71, 1.59), television (aOR: 1.09; 95% CI: 0.72, 1.65), and short messaging service (aOR: 1.29; 95% CI: 0.51, 3.22) marginally increase the risk of teenage pregnancy. We did not find any pairwise interactions between the different exposure variables. CONCLUSIONS: Our results highlight the need to improve the content and key messages of contraceptive and family planning messages in the Philippines, especially those that are broadcasted online and in print media. There is also a need to increase the reach of these different family planning and contraception messages, especially by utilizing social media and other print and online media platforms commonly used by the youth.

Adolescent pregnancy is associated with adverse health, psychosocial, and economic outcomes. As of 2017, the proportion of women aged 15­19 who have begun childbearing in the Philippines is 9%. To counter this, the Philippine government and its partners in the private sector disseminate family planning and contraception information to the general population. Thus, we studied the effect of being exposed to these family planning and contraception information in different forms of media and their effect of teenage pregnancy. We analysed the 2017 Philippine National Demographic and Health Survey. After controlling for the effect of other variables, we found that these family planning and contraception information had little effect on teenage pregnancy in the country. These findings highlight the need to improve the content and key messages of contraceptive and family planning messages, and improve their coverage in the general population.

Mechanical Ventilation and Hospital-Acquired Venous Thromboembolism Among Critically Ill Children.

OBJECTIVES: To estimate the occurrence of, and evaluate associations between, hospital-acquired venous thromboembolism (HA-VTE) and invasive mechanical ventilation (MV) among children hospitalized in the PICU. METHODS: We performed a multicenter, retrospective cohort study comparing HA-VTE frequencies among subjects <18 years of age hospitalized in the PICU from January 2018 through December 2019 among 47 participating centers, via the Pediatric Health Information Systems registry. We excluded perinatal encounters, those with VTE present at admission, and those with observational status. The primary outcome was the proportion of HA-VTE events before hospital discharge, including extremity deep venous thrombosis, pulmonary embolism, and organ-specific deep venous thrombosis. The HA-VTE frequencies were compared using χ2 tests. The association between HA-VTE and MV was investigated via multivariable logistic regression, adjusting for previously described VTE risk factors. RESULTS: Of the 205 231 PICU encounters identified for study, 70 829 (34.5%) underwent MV. The occurrence of HA-VTE was 2.2% and was greater among children who received, versus did not receive, MV (4.4% versus 1.1%, P < .001). Multivariable logistic regression revealed significant association between MV and HA-VTE (odds ratio 2.51, 95% confidence interval 2.33-2.69; P < .001). CONCLUSIONS: In this multicenter, retrospective, registry-based cohort study, HA-VTE were diagnosed in 2.2% of critically-ill children, and after adjustment for central venous catheterization, MV independently increased the risk of HA-VTE 2.5-fold. These findings warrant prospective validation to inform the design of future risk-stratified clinical trials of thromboprophylaxis in critically-ill children.

Determinants of consistent condom use among Filipino women: Results from the 2017 Philippine National Demographic and Health Survey.

BACKGROUND: Consistent condom use in women, defined as the self-reported usage of male condom in every sexual encounter of the respondent with her most recent partner in the last 12 months, had been perennially low in the Philippines. This is despite consistent condom use being a tested and proven public health intervention to prevent unwanted pregnancy and sexually transmitted infections. Considering the high fertility rate, teenage pregnancy rate, and the rapidly increasing incidence of HIV in the country, we identified the determinants of consistent condom use in the Philippines. METHODS: We used data from the individual recode of the 2017 Philippine National Demographic and Health Survey. We used logistic regression for survey data to identify factors associated with consistent condom use. RESULTS: Out of 25,074 respondents, only 261 (1.13%) have used condoms consistently with their most recent partner. Reach of information and education campaigns on contraceptive use via different media ranged from 62% via television to 7% via short messaging service. After adjusting for confounders, those who were able to ask their partners to use condoms during sexual intercourse have 6.18 times (adjusted odds ratio (aOR): 6.18; 95% Confidence Interval (95% CI): 2.02. 18.94) greater odds of consistent condom use than those who were unable to ask their partners to use condoms during sexual intercourse. Meanwhile, HIV knowledge (aOR: 1.16; 95% CI: 0.98, 1.38) and hearing about contraception in television (aOR: 1.54; 95% CI: 1.00, 2.38) have weaker associations with consistent condom use. CONCLUSIONS: The low percentage of those who use condoms consistently, together with the low reach of information and education campaigns, highlight the need to implement multi-faceted and context-specific interventions to promote sexual agency and/or consistent condom use to address the burden of unwanted pregnancies and HIV in the Philippines.

Prevalence and determinants of home delivery in urban and rural Philippines: Evidence from the 2017 National Demographic and Health Survey.

BACKGROUND: Women's choice of place of delivery has implications on maternal and child mortality. This study aims to provide an updated and detailed comparison of prevalence and determinants of home delivery in the Philippines, and in urban and rural communities. METHODS: Based on data from the 2017 Philippine National Demographic and Health Survey (NDHS), we estimated the prevalence of home delivery and determined factors influencing women's decision to deliver at home. Analyses were restricted to data from 7229 women who were cohabiting or married, and their last-born child using logistic regression methods for survey data. RESULTS: There remain a considerable proportion of women aged 15-49 years old who delivered at home (17.92% (95% confidence interval (CI): 15.77, 20.30)). More women in rural areas delivered at home (23.53% (95% CI: 20.38, 26.99)) than their counterparts in urban areas (10.72% (95% CI: 8.23, 13.85)), reflecting a significant difference in the home delivery prevalence of women relative to their place of residence. Our regression analyses showed that there is a relatively greater effect observed for the rural population in most of the proximal factors considered including birth order, women's decision-making power, and emergency preparedness during pregnancy. Wealth index has the most pronounced effect with a significant increase in odds of home delivery among urban and rural women of the lowest wealth categories. CONCLUSION: The use of institutional childbirth services remains suboptimal in the Philippines with significant disparities between urban and rural communities. Current strategies therefore need to adopt a multi-sectoral approach to address the complex factors influencing women's decision on place of delivery. Targeted efforts specific to population groups should also be made to contextualize and co-create health care services and solutions that will motivate them to deliver in health facilities.

COVID-19 vaccine hesitancy among rural Oklahomans.

INTRODUCTION: COVID-19 vaccination is widely recommended as a prevention strategy; however, vaccine uptake is disproportionately lower among rural Americans compared to their urban counterparts. Development of public health activities to address the rural-urban vaccine gap requires an understanding of determinants of vaccine hesitation. The present study explores perceptions of and barriers to COVID-19 vaccination among rural Oklahomans. METHODS: Between March and May 2021, 222 residents, unvaccinated for COVID-19, within rural Oklahoma counties completed a cross-sectional, online questionnaire to qualitatively assess perceptions, benefits, and concerns regarding getting vaccinated for COVID-19. RESULTS: Approximately two-fifths of rural respondents in the present study were hesitant to get vaccinated, even when a vaccine was made available to them. Major factors included limited knowledge and understanding about the vaccine, including potential side-effects and long-term complications, as well as skepticism surrounding COVID-19 vaccine development and efficacy. Among the potential perceived benefits of vaccination were protecting the health of vulnerable individuals and the ability to return to normal day-to-day activities. CONCLUSION: Increases in COVID-19 cases and deaths in rural areas are expected to continue as new variants are introduced within communities. The present findings highlight the need for the development of culturally tailored vaccine information, to be disseminated by local leaders within rural communities.

ACE domains and depression: Investigating which specific domains are associated with depression in adulthood.

BACKGROUND: The study of adverse childhood experiences (ACEs) has shown deleterious effects throughout adulthood. Little attention, however, is given to specific ACE domains as they relate to mental health outcomes, as most studies use cumulative ACE score models. OBJECTIVE: The current study disaggregates ACEs domains to investigate their independent effect (while controlling for each other and other demographic covariates) on receiving a depression diagnosis as an adult. PARTICIPANTS AND SETTING: Data were obtained from the Behavioral Risk Factor Surveillance Survey (BRFSS; N = 52,971). METHODS: To control and account for the numerical number of ACEs, separate models were run among each ACE score (e.g., those with an ACE score of exactly two, three, etc.). An aggregate model with all participants is also included. RESULTS: Across all ACE scores, those with a history of family mental illness had the highest likelihood of receiving a depression diagnosis. The second strongest association were those with sexual abuse. No other trends were found among the six other domains. Further, those with a combination of family mental illness and sexual abuse had the highest odds of depression. CONCLUSIONS: Mental health providers should consider the numerical number of ACEs as well as the specific ACE domains (specifically, family mental illness and sexual abuse). Additionally, this provides evidence for a possible weighting schema for the ACEs scale.

The Effects of Individual and Dual ACE Domains on Binge Drinking: Comparisons by Gender.

BACKGROUND: Adverse Childhood Experiences (ACEs) show predictive utility concerning binge drinking. However, the literature is limited by 1. a focus on cumulative ACEs with little regard to specific domains, 2. a focus on those with the highest ACE scores, and 3. little consideration for gender differences. These approaches are problematic as ACE categories are fundamentally different, yet little distinction is given to specific ACE domains. The current study investigates which individual and dual ACE domain combinations are associated with binge drinking. METHODS: Data were obtained from the Behavioral Risk Factor Surveillance System (2011-2017; N = 80,391). A series of ANCOVAs were conducted to determine the association between single and dual combination ACE domains and binge drinking. RESULTS: Results show gendered effects of ACEs on binge drinking such that at 0, 1, and 2 ACEs, males reported statistically higher rates. For males with exactly two ACEs, combinations of either sexual abuse or family incarceration presented the highest levels of binge drinking- with the highest mean binge drinking score being the exact combination of the two. This contrasts with males with 1 ACE, where experiencing family incarceration or sexual abuse, as a single domain, did not represent significant risk above the average of having a single ACE. CONCLUSIONS: Results suggest that males may be resilient to either of these domains as singular events, yet when found in combination, may present a synergistic effect that increases the likelihood of binge drinking. Due to lower overall binge drinking rates, no significant patterns were found among females.

Rural College Students' Amenability Toward Using At-Home Human Immunodeficiency Virus and Sexually Transmitted Infection Testing Kits.

BACKGROUND: College students residing in rural areas of the United States have limited access to human immunodeficiency virus (HIV) and sexually transmitted infection (STI) screening programs; yet, have increased rates of infection. METHODS: Students (N = 326), attending a state university located within a rural community, completed an online survey containing open-ended questions that gauged their perceptions and experiences with HIV/STI testing, amenability to at-home testing technology, and preferences for obtaining at-home testing kits. Inductive coding was used to create themes for each open-ended question. RESULTS: Students encounter a number of perceived barriers to accessing clinical HIV/STI testing venues including cost, utilization of parents' medical insurance, and stigma. Students desired screening paradigms that allow for a greater sense of privacy and the ability to be empowered through self-sampling methods. This includes the use of at-home testing kits, which could be accessed via mail, campus, or the local community. Although students were overwhelmingly amenable to using at-home testing, students discussed concerns with potential user error that could impact testing accuracy. CONCLUSIONS: Study findings suggest the importance of developing less clinically oriented systems of HIV/STI screening, which allow students to choose from an array of screening options. Removing perceived barriers, notably access and privacy concerns, to HIV/STI testing by leveraging at-home testing is one potential method to increase screening uptake among this at-risk population.

Education, Perceptions, and Delivery: Factors Shaping the Perceived Role in the Pre-Exposure Prophylaxis (PrEP) Care Continuum Among a Sample of Osteopathic Medical Students.

Pre-exposure prophylaxis (PrEP) uptake has been suboptimal despite its demonstrated efficacy in reducing the risk of HIV acquisition. Medical education is one distal determinant that shapes medical providers' perceived role in the PrEP care continuum. However, there is limited understanding of how osteopathic medical students and those wanting to practice in rural areas perceive their role in the PrEP care continuum in the domains of PrEP awareness, uptake, and adherence and retention. Twenty-one semistructured interviews were conducted (March 2019-April 2020) to assess what shapes osteopathic medical students' perceived role in the PrEP care continuum. Participants noted a lack of adequate sexual health training, personal perceptions concerning PrEP use, and ambiguity concerning which of the medical specialties should deliver PrEP. Osteopathic medical schools can incorporate more inclusive and holistic sexual health and PrEP curricula to address these barriers and better prepare osteopathic medical students for their future role in the PrEP care continuum.

Examining Profiles of Latinx Sexual Minority Adolescents Associated with Suicide Risk.

Few studies have focused on within-group heterogeneity about specific factors that make lesbian, gay, or bisexual (LGB) Latinx adolescents at greater odds than other LGB adolescents for suicide We take a unique mixture-modeling approach by creating profiles of Latinx LGB adolescents based on suicide risk factors used in previous investigations (bullying, alcohol, sleep, social media, and poor grades). We use these profiles in a logistic regression to investigate suicidality A sample of 686 LGB, Latinx adolescents were used in a latent profile analysis yielding four distinct profiles. Class 4 represented the highest risk, with high rates of bullying, alcohol, poor grades, and use of electronics, while class 3 represented the lowest risk with low rates of bullying and alcohol Results speak to the need to address suicidal ideation through multiple factors, noting the strong association that both bullying and alcohol have with suicidal ideation.

Perceived Confidentiality Risks of Mobile Technology-Based Ecologic Momentary Assessment to Assess High-Risk Behaviors Among Rural Men Who Have Sex with Men.

Although men who have sex with men (MSM) within rural communities are disproportionately impacted by HIV, limited HIV research and programmatic resources are directed to these communities within the U.S. There is a need for improved behavioral data collection methods to obtain more detailed information on the relationship between rural environments, sexual behavior, and substance use. Utilization of mobile health (mHealth) technologies, such as ecologic momentary assessment (EMA), has been advocated for; however, limited research has evaluated its utility among rural MSM. Forty MSM residing in rural Oklahoma were recruited to complete in-depth interviews related to participating online/mobile-based HIV prevention research. Men described a willingness to participate in HIV and substance use studies that use EMA methodologies for data collection; however, they raised various research-related concerns. In particular, participants indicated potential privacy and confidentiality concerns related to the use of the mobile technology-based EMA in public and the storage of data by researchers. Given the varying degree of sexual orientation and substance use disclosure by participants, rural MSM were largely concerned with being inadvertently "outed" within their communities. Men described the various strategies they could employ to protect private information and methods to minimize research risk. Study findings suggest that EMA is an acceptable research methodology for use among rural MSM in the context of HIV and sexual health information, when privacy and confidentiality concerns are adequately addressed. Input from community members and stakeholders is necessary to identify potential areas of concerns for participants prior to data collection.

Client perspectives on the accessibility and quality of substance use treatment during the COVID-19 pandemic.

BACKGROUND: People who use drugs have been particularly vulnerable during the COVID-19 pandemic because of their unique social, harm reduction, and treatment needs. These unique needs and challenges have significant influence on the severity of their substance use, mental health symptomatology, willingness to engage in treatment, and adherence to treatment options. This has included immense challenges related to the dissemination of COVID-19 messaging and the need for harm reduction and treatment service entities to adopt new formats to continue operation. METHODS: In-depth interview data were collected people who use drugs (N=24) residing in Oklahoma from November 2020 through February 2021 to assess perspectives on (1) their access to harm reduction, substance use prevention, and treatment programs during the COVID-19 pandemic, (2) the perceived quality of such services and programs during this time, and (3) the perceived availability of tailored COVID-19 information. RESULTS: Several factors emerged related to accessing and quality of substance use services during COVID-19, including poor accessibility (e.g., internet access), diminished quality (i.e., lack of social support), and lack of tailored COVID-19 prevention and treatment messaging. CONCLUSIONS: Upticks in COVID-19 cases and deaths are expected to continue as new SARS-CoV-2 variants are introduced. The present findings highlight the need for tailored COVID-19 messaging (e.g., minimizing the sharing of substance use supplies that can spread COVID-19, mask wearing, COVID-19 vaccination), which is responsive to unique needs of substance using populations. Similarly, as prevention and treatment programs are delivered online, efforts are necessary to ensure equitable access and enhanced quality of services.

Sex differences in cardiovascular morbidity associated with familial hypercholesterolaemia: A retrospective cohort study of the UK Simon Broome register linked to national hospital records.

BACKGROUND AND AIMS: The UK Simon Broome (SB) familial hypercholesterolaemia (FH) register previously reported 3-fold higher standardised mortality ratio for cardiovascular disease (CVD) in women compared to men from 2009 to 2015. Here we examined sex differences in CVD morbidity in FH by national linkage of the SB register with Hospital Episode Statistics (HES). METHODS: Of 3553 FH individuals in the SB register (aged 20-79 years at registration), 2988 (52.5% women) had linked HES records. Standardised Morbidity Ratios (SMbR) compared to an age and sex-matched UK general practice population were calculated [95% confidence intervals] for first CVD hospitalisation in HES (a composite of coronary heart disease (CHD), myocardial infarction (MI), stable or unstable angina, stroke, TIA, peripheral vascular disease (PVD), heart failure, coronary revascularisation interventions). RESULTS: At registration, men had significantly (p < 0.001) higher prevalence of previous CHD (24.8% vs 17.6%), previous MI (13.2% vs 6.3%), and were commenced on lipid-lowering treatment at a younger age than women (37.5 years vs 42.3 years). The SMbR for composite CVD was 6.83 (6.33-7.37) in men and 7.55 (6.99-8.15) in women. In individuals aged 30-50 years, SMbR in women was 50% higher than in men (15.04 [12.98-17.42] vs 10.03 [9.01-11.17]). In individuals >50 years, SMbR was 33% higher in women than men (6.11 [5.57-6.70] vs 4.59 [4.08-5.15]). CONCLUSIONS: Excess CVD morbidity due to FH remains markedly elevated in women at all ages, but especially those aged 30-50 years. This highlights the need for earlier diagnosis and optimisation of lipid-lowering risk factor management for all FH patients, with particular attention to young women with FH.
