Receipt of Gender-Affirming Surgeries Among Transgender and Gender Diverse Veterans.

BACKGROUND: Gender-affirming surgery (GAS) can be an important part of comprehensive care for transgender and gender diverse (TGD) individuals, but this care is not provided by the Department of Veterans Affairs (VA) because of an exclusion in the medical benefits package. OBJECTIVE: To describe the receipt of GAS by veterans and assess the associations between key sociodemographic characteristics and receipt of chest ("top") and genital ("bottom") surgeries. DESIGN: Cross-sectional national survey (the GendeR Affirming Care Evaluation (GRACE)), among TGD Veterans conducted between September 2022 and July 2023. PARTICIPANTS: A total of 6653 Veterans (54% response rate) completed the survey. MAIN MEASURES: Self-reported "top" and "bottom" GAS were key outcomes. Covariates included gender identity, sex assigned at birth, age, race, ethnicity, income, employment status, education, relationship status, sexual orientation, and geographic region. KEY RESULTS: Among all respondents, 39% had ≥ 1 GAS. Among the 4430 veterans interested in top surgery, 38% received it; 23% of 3911 veterans interested in bottom surgery had received it. In multivariable models, older age (50 + vs. 18-39) was associated with higher receipt of top and bottom surgery while nonbinary gender identity (vs. binary gender identity), lower household income (< $50,000 vs. > $75,000), less education (less than a college graduate vs. Master's degree or more), sexual orientations other than heterosexual, and residing in a region other than the Pacific were associated with lower receipt of top and bottom surgery. Individuals assigned male (vs. assigned female) at birth had lower receipt of top surgery and higher receipt of bottom surgery. CONCLUSIONS: GAS receipt was low and there were important disparities by gender, sex, income, education, sexual orientation, and region. By removing the exclusion to providing GAS, VA could reduce barriers to accessing GAS and decrease disparities among TGD veterans.

Non-affirmation minority stress, internalized transphobia, and subjective cognitive decline among transgender and gender diverse veterans aged 45 years and older.

OBJECTIVES: To examine the associations of two measures of minority stress, non-affirmation minority stress and internalized transphobia, with subjective cognitive decline (SCD) among transgender and gender diverse (TGD) veterans. METHOD: We administered a cross-sectional survey from September 2022 to July 2023 to TGD veterans. The final analytic sample included 3,152 TGD veterans aged ≥45 years. We used a generalized linear model with quasi-Poisson distribution to calculate prevalence ratios (PR) and 95% confidence intervals (CIs) measuring the relationship between non-affirmation minority stress and internalized transphobia and past-year SCD. RESULTS: The mean age was 61.3 years (SD = 9.7) and the majority (70%) identified as trans women or women. Overall, 27.2% (n = 857) reported SCD. Adjusted models revealed that TGD veterans who reported experiencing non-affirmation minority stress or internalized transphobia had greater risk of past-year SCD compared to those who did not report either stressor (aPR: 1.09, 95% CI: 1.04-1.15; aPR: 1.19, 95% CI: 1.12-1.27). CONCLUSION: Our findings demonstrate that proximal and distal processes of stigma are associated with SCD among TGD veterans and underscore the need for addressing multiple types of discrimination. Above all, these results indicate the lasting sequelae of transphobia and need for systemic changes to prioritize the safety and welfare of TGD people.

A Long-Term Comparison between the AethLabs MA350 and Aerosol Magee Scientific AE33 Black Carbon Monitors in the Greater Salt Lake City Metropolitan Area.

Black carbon (BC) or soot contains ultrafine combustion particles that are associated with a wide range of health impacts, leading to respiratory and cardiovascular diseases. Both long-term and short-term health impacts of BC have been documented, with even low-level exposures to BC resulting in negative health outcomes for vulnerable groups. Two aethalometers-AethLabs MA350 and Aerosol Magee Scientific AE33-were co-located at a Utah Division of Air Quality site in Bountiful, Utah for just under a year. The aethalometer comparison showed a close relationship between instruments for IR BC, Blue BC, and fossil fuel source-specific BC estimates. The biomass source-specific BC estimates were markedly different between instruments at the minute and hour scale but became more similar and perhaps less-affected by high-leverage outliers at the daily time scale. The greater inter-device difference for biomass BC may have been confounded by very low biomass-specific BC concentrations during the study period. These findings at a mountainous, high-elevation, Greater Salt Lake City Area site support previous study results and broaden the body of evidence validating the performance of the MA350.

Patient Experiences and Provider Perspectives on Accessing Gender-Affirming Surgical Services in the Veterans Health Administration.

BACKGROUND: Transgender and gender diverse (TGD) veterans have a greater prevalence of suicide morbidity and mortality than cisgender veterans. Gender-affirming surgery (GAS) has been shown to improve mental health for TGD veterans. In 2021, the Veterans Health Administration (VHA) announced the initiation of a rulemaking process to cover GAS for TGD patients. OBJECTIVE: This study explores patients' and providers' perspectives about access to GAS and other gender-affirming medical interventions not offered in the VHA including barriers, facilitators, and clinical and policy recommendations. PARTICIPANTS: TGD patients (n = 30) and VHA providers (n = 22). APPROACH: Semi-structured telephone interviews conducted from August 2019 through January 2020. Two TGD analysts used conventional and directed content analysis to code transcribed data. KEY RESULTS: VHA policy exclusions were the most cited barrier to GAS. Additional barriers included finding information about GAS, traveling long distances to non-VHA surgeons, out-of-pocket expenses, post-surgery home care, and psychological challenges related to the procedure. Factors facilitating access included surgical care information from peers and VHA providers coordinating care with non-VHA GAS providers. Pre- and post-operative care through the VHA also facilitated receiving surgery; however, patients and providers indicated that knowledge of these services is not widespread. Respondents recommended disseminating information about GAS-related care and resources to patients and providers to help patients navigate care. Additional recommendations included expanding access to TGD mental health specialists and establishing referrals to non-VHA GAS providers through transgender care coordinators. Finally, transfeminine patients expressed the importance of facial GAS and hair removal. CONCLUSIONS: A policy change to include GAS in the VHA medical benefits package will allow the largest integrated healthcare system in the United States to provide evidence-based GAS services to TGD patients. For robust and consistent policy implementation, the VHA must better disseminate information about VHA-provided GAS-related care to TGD patients and providers while building capacity for GAS delivery.

Barriers and Facilitators to Gender-affirming Hormone Therapy in the Veterans Health Administration.

BACKGROUND: In 2011, the Veterans Health Administration (VHA) established a policy for the delivery of transition-related services, including gender-affirming hormone therapy (GAHT), for transgender and gender diverse (TGD) patients. In the decade since this policy's implementation, limited research has investigated barriers and facilitators of VHA's provision of this evidence-based therapy that can improve life satisfaction among TGD patients. PURPOSE: This study provides a qualitative summary of barriers and facilitators to GAHT at the individual (e.g., knowledge, coping mechanisms), interpersonal (e.g., interactions with other individuals or groups), and structural (e.g., gender norms, policies) levels. METHODS: Transgender and gender diverse patients (n = 30) and VHA healthcare providers (n = 22) completed semi-structured, in-depth interviews in 2019 regarding barriers and facilitators to GAHT access and recommendations for overcoming perceived barriers. Two analysts used content analysis to code and analyze transcribed interview data and employed the Sexual and Gender Minority Health Disparities Research Framework to organize themes into multiple levels. RESULTS: Facilitators included having GAHT offered through primary care or TGD specialty clinics and knowledgeable providers, with patients adding supportive social networks and self-advocacy. Several barriers were identified, including a lack of providers trained or willing to prescribe GAHT, patient dissatisfaction with prescribing practices, and anticipated or enacted stigma. To overcome barriers, participants recommended increasing provider capacity, providing opportunities for continual education, and enhancing communication around VHA policy and training. CONCLUSIONS: Multi-level system improvements within and outside the VHA are needed to ensure equitable and efficient access to GAHT.

Veterans Health Administration (VHA) policy mandates the provision of several gender-affirming health services, including gender-affirming hormone therapy (GAHT). GAHT can improve quality of life among transgender and gender diverse (TGD) patients by more closely aligning their physical self with their internal sense of self. We conducted interviews with 30 TGD patients and 22 VHA healthcare providers to gather their perspectives on barriers and facilitators to GAHT in the VHA. Findings revealed that facilitators of GAHT access included information sharing through social networks and relying on providers in primary care or specialized TGD health clinics for prescribing, while barriers included a shortage of trained providers and patient dissatisfaction with prescribing practices. Anticipating or experiencing stigma from providers and other patients was also identified as a barrier to GAHT. To overcome barriers, participants recommended increasing provider capacity, offering continuous education on GAHT prescribing, and improving communication about VHA policies and training. Comprehensive improvements at various levels, both within and outside the VHA, are necessary to improve access to this important evidence-based treatment for TGD patients.

"Letting Go and Staying Connected": Substance Use Outcomes from a Developmentally Targeted Intervention for Parents of College Students.

We present results of a randomized, controlled, efficacy trial of a handbook intervention for parents of first-year college students. The aim of the interactive intervention was to decrease risk behaviors by increasing family protective factors. The handbook, based in self-determination theory and the social development model, provided evidence-based and developmentally targeted suggestions for parents to engage with their students in activities designed to support successful adjustment to college. We recruited 919 parent-student dyads from incoming students enrolled at a university in the U.S. Pacific Northwest and randomly assigned them to control and intervention conditions. We sent handbooks to intervention parents in June before students' August matriculation. Research assistants trained in motivational interviewing contacted parents to encourage use of the handbook. Control parents and students received treatment as usual. Participants completed baseline surveys during their final semester in high school (time 1) and their first semester at college (time 2). Self-reported frequency of alcohol, cannabis, and simultaneous use increased across both handbook and control students. In intent-to-treat analyses, odds of increased use were consistently lower and of similar magnitude for students in the intervention condition than in the control condition, and odds of first-time use were also lower in the intervention condition. Contact from research assistants predicted parents' engagement, and parent and student report of active engagement with handbook predicted lower substance use among intervention than control students across the transition to college. We developed a low-cost, theory-based handbook to help parents support their young adult children as they transition to independent college life. Students whose parents used the handbook were less likely to initiate or increase substance use than students in the control condition during their first semester in college.ClinicalTrials.gov Identifier: NCT03227809.

Validating Data-Driven Methods for Identifying Transgender Individuals in the Veterans Health Administration of the US Department of Veterans Affairs.

We sought to operationalize and validate data-driven approaches for identifying transgender individuals in the Veterans Health Administration (VHA) of the US Department of Veterans Affairs (VA) through a retrospective analysis using VA administrative data from 2006-2018. Besides diagnoses of gender identity disorder (GID), a combination of non-GID data elements was used to identify potentially transgender veterans, including 1) an International Classification of Diseases (Ninth or Tenth Revision) code of endocrine disorder, unspecified or not otherwise specified; 2) receipt of sex hormones not associated with the sex documented in the veteran's records (gender-affirming hormone therapy); and 3) a change in the veteran's administratively recorded sex. Both GID and non-GID data elements were applied to a sample of 13,233,529 veterans utilizing the VHA of the VA between January 2006 and December 2018. We identified 10,769 potentially transgender veterans. Based on a high positive predictive value for GID-coded veterans (83%, 95% confidence interval: 77, 89) versus non-GID-coded veterans (2%, 95% confidence interval: 1, 11) from chart review validation, the final analytical sample comprised only veterans with a GID diagnosis code (n = 9,608). In the absence of self-identified gender identity, findings suggest that relying entirely on GID diagnosis codes is the most reliable approach for identifying transgender individuals in the VHA of the VA.

Client Satisfaction with Community Health Workers in HIV Care Teams.

Community health workers (CHWs) integrated in human immunodeficiency virus (HIV) care teams undertake a variety of tasks to help patients navigate health care, develop care plans, and address social needs. Given the broad role of CHWs in HIV care, we sought to understand which client attributes are associated with various dimensions of CHW satisfaction using a sample of 204 people with HIV (PWH) from various geographic regions across the United States. Multivariable linear regressions were used to determine which client attributes were associated with complete satisfaction with CHWs using 10 validated measures. The mean age of participants was 40.6 years old (SD = 12.8) and over 70% were Black or African American. Adjusted models reveal clients who were female, have marginal health literacy, or have a substance use disorder diagnosis were more likely to not be completely satisfied across multiple dimensions (p ≤ .05). Conversely, being housed and having a mental health diagnosis were associated with being more likely to be completely satisfied (p ≤ .04). Clients' sociodemographic characteristics and health conditions may be indicative of unique needs, leading to differing expectations of CHWs. CHW training modalities should consider the complex interplay of care needs based upon different client backgrounds and experiences among PWH. Addressing unique needs resulting from social determinants of health and that arise from conditions co-occurring with HIV, such as substance use disorders, should be incorporated into CHW service delivery.

Beyond Gender Identity Disorder Diagnoses Codes: An Examination of Additional Methods to Identify Transgender Individuals in Administrative Databases.

BACKGROUND: Large administrative databases often do not capture gender identity data, limiting researchers' ability to identify transgender people and complicating the study of this population. OBJECTIVE: The objective of this study was to develop methods for identifying transgender people in a large, national dataset for insured adults. RESEARCH DESIGN: This was a retrospective analysis of administrative claims data. After using gender identity disorder (GID) diagnoses codes, the current method for identifying transgender people in administrative data, we used the following 2 strategies to improve the accuracy of identifying transgender people that involved: (1) Endocrine Disorder Not Otherwise Specified (Endo NOS) codes and a transgender-related procedure code; or (2) Receipt of sex hormones not associated with the sex recorded in the patient's chart (sex-discordant hormone therapy) and an Endo NOS code or transgender-related procedure code. SUBJECTS: Seventy-four million adults 18 years and above enrolled at some point in commercial or Medicare Advantage plans from 2006 through 2017. RESULTS: We identified 27,227 unique transgender people overall; 18,785 (69%) were identified using GID codes alone. Using Endo NOS with a transgender-related procedure code, and sex-discordant hormone therapy with either Endo NOS or transgender-related procedure code, we added 4391 (16%) and 4051 (15%) transgender people, respectively. Of the 27,227 transgender people in our cohort, 8694 (32%) were transmasculine, 3959 (15%) were transfeminine, and 14,574 (54%) could not be classified. CONCLUSION: In the absence of gender identity data, additional data elements beyond GID codes improves the identification of transgender people in large, administrative claims databases.

The Promise of Patient Portals for Individuals Living With Chronic Illness: Qualitative Study Identifying Pathways of Patient Engagement.

BACKGROUND: Patients play a critical role in managing their health, especially in the context of chronic conditions like diabetes. Electronic patient portals have been identified as a potential means to improve patient engagement; that is, patients' involvement in their care. However, little is known about the pathways through which portals may help patients engage in their care. OBJECTIVE: Our objective is to understand how an electronic patient portal facilitates patient engagement among individuals with diabetes. METHODS: This qualitative study employed semistructured telephone interviews of 40 patients living with diabetes since at least 2011, who had experienced uncontrolled diabetes, and had used secure messaging through a portal at least 4 times over 18 months. The interviews were recorded, transcribed, coded, and analyzed using primarily an inductive approach to identify how patients living with diabetes use an online health portal to support diabetes self-management. RESULTS: Overall, patients who used the portal reported feeling engaged in their health care. We identified four pathways by which the portal facilitates patient engagement and some challenges. The portal provides a platform that patients use to (1) better understand their health by asking questions about new symptoms, notes, or labs, (2) prepare for medical appointments by reviewing labs and notes, (3) coordinate care between VA (Veterans Affairs) and non-VA health care teams, and (4) reach out to providers to request help between visits. Several patients reported that the portal helped improve the patient-provider relationship; however, aspects of the portal design may hinder engagement for others. Patients reported challenges with both secure messaging and access to medical records that had negative impacts on their engagement. Benefits for patient engagement were described by many types of portal users with varying degrees of diabetes control. CONCLUSIONS: Patient portals support engagement by facilitating patient access to their health information and by facilitating patient-provider communication. Portals can help a wide range of users engage with their care.

Surgery Task Load Index in Cardiac Surgery: Measuring Cognitive Load Among Teams.

Background. The most commonly used subjective assessment of perceived cognitive load, the NASA Task Load Index (TLX), has proven valuable in measuring individual load among general populations. The surgery task load index (SURG-TLX) was developed and validated to measure cognitive load specifically among individuals within a surgical team. Notably, the TLX lacks temporal sensitivity in its typical retrospective administration. Objective. This study sought to expand the utility of SURG-TLX by investigating individual measures of cognitive load over time during cardiac surgery, and the relationship between individual and team measures of cognitive load and proxies for surgical complexity. Materials & Methods. SURG-TLX was administered retrospectively in the operating room immediately following each case to approximate cognitive load before, during, and after cardiopulmonary bypass for cardiac surgery team members (surgeon, anesthesiologist, and perfusionist). Correlations were calculated to determine the relationship of individual and team measures of cognitive load over the entire procedure with bypass length and surgery length. Results. Results suggest that perceived cognitive load varies throughout the procedure such that cognitive load during bypass significantly differs compared to before or after bypass, across all 3 roles. While on bypass, results show that anesthesiologists experience significantly lower levels of perceived cognitive load than both surgeons and perfusionists. Correlational analyses reveal that perceived cognitive load of both the surgeon and the team had significant positive associations with bypass length and surgery length. Conclusion. Our findings support the utility of SURG-TLX in real cardiac cases as a measure of cognitive load over time, and on an individual and team-wide basis.

Towards a rapid assessment protocol for identifying pit lakes worthy of restoration.

Before the introduction of reclamation legislation in South Africa, final cut lakes in mining areas were left without any restoration while the final excavation was not back filled. Characteristics of these lacustrine water bodies vary considerably, but they are often linear in shape, large (1-30 ha), deep (2-30 m) and have poorly developed littoral zones. With water tables often near the surface; a variety of vascular hydrophytes can colonize these bodies, thus establishing emerging wetland type ecosystems. These, man-made aquatic structures that are (unintentionally) created potentially offers some realistic and inexpensive mitigation options for some of the negative impacts associated with mining, i.e. these water bodies can become useful by yielding potentially valuable services. However, no method currently exists to compare and rank these water bodies according ecological integrity and the expected monetary value to be derived from them in order to select sites for restoration. To answer this need, we applied an index to determine the ability of these water bodies to provide useful services in their current state. The index was then used to derive estimates of the monetary value of potential services in order to allow comparison with the cost of restoring the water body in question or to compare with other pit lakes. We present a South African case study to illustrate the method. As far as could be established, this is the first attempt towards creating a rapid assessment tool as standardised way of comparing pit lakes that allows for the ranking and identification of those pit lakes worthy of restoration.

Associations between physical activity and BMI, body fatness, and visceral adiposity in overweight or obese Latino and non-Latino adults.

BACKGROUND/OBJECTIVES: Although several studies have reported associations between moderate to vigorous physical activity (MVPA), body fatness and visceral adipose tissue (VAT), the extent to which associations differ among Latinos and non-Latinos remains unclear. This study evaluated the associations between body composition and MVPA in Latino and non-Latino adults. SUBJECTS/METHODS: An exploratory, cross-sectional analysis was conducted using baseline data collected from 298 overweight adults enrolled in a 12-month randomized controlled trial that tested the efficacy of text messaging to improve weight loss. MVPA, body fatness and VAT were assessed by waist-worn accelerometry, dual-energy x-ray absorptiometry (DXA), and DXA-derived software (GE CoreScan GE, Madison, WI, USA), respectively. Participants with <5 days of accelerometry data or missing DXA data were excluded; 236 participants had complete data. Multivariable linear regression assessed associations between body composition and MVPA per day, defined as time in MVPA, bouts of MVPA (time per bout ⩾10 min), non-bouts of MVPA (time per bout <10 min) and meeting the 150-min MVPA guideline. The modifying influence of ethnicity was modeled with a multiplicative interaction term. RESULTS: The interaction between ethnicity and MVPA in predicting percent body fat was significant (P=0.01, 95% confidence interval (CI) (0.58, 4.43)) such that a given increase in MVPA was associated with a greater decline in total body fat in non-Latinos compared with Latinos (adjusted for age, sex and accelerometer wear time). There was no interaction between ethnicity and MVPA in predicting VAT (g) (P=0.78, 95% CI (-205.74, 273.17)) and body mass index (BMI) (P=0.18, 95% CI (-0.49, 2.26)). CONCLUSIONS: An increase in MVPA was associated with a larger decrease in body fat, but neither BMI nor VAT, in non-Latinos compared with Latinos. This suggests that changes in VAT and BMI in response to MVPA may be less influenced by ethnicity than is total body fatness.

Gastric emptying for liquids of different compositions in children.

BACKGROUND: Pre-operative fasting balances safety against patient discomfort. We compared the gastric emptying profiles of a novel clear, high protein drink against a "traditional" clear and a non-clear fluid. METHODS: We conducted a prospective cross-sectional study with 48 healthy volunteers, eight to 14 yr of age, fasted overnight and without risk factors for abnormal gastrointestinal motility. Subjects were randomized in equal ratio to ingest 296 ml of apple juice, 2% milk or Ensure Clear. The gastric antrum was seen by ultrasound in the right lateral decubitus position at baseline, after ingestion, then every 30 min thereafter until return to baseline or six h. Gastric antral cross-sectional area was measured independently by two anaesthetists, and compared between drinks. RESULTS: Gastric emptying differed between apple juice, 2% milk and Ensure Clear by analysis of co-variance (P<0.0001), and was faster in males than females (P<0.01). The terminal phase however was similar using interval-censored time to gastric emptying in a survival model (P=0.17) or by comparing proportions with empty stomach vs not empty at 90 min (P=1.0), 120 min (P=0.32), 150 min (P=0.11), 180 min (P=0.76) or 210 min (P=1.0). CONCLUSIONS: Despite early differences, clearance from the stomach of apple juice, 2% milk or Ensure Clear is similar at the terminal phase, which is the period of greatest relevance to preoperative fasting recommendations. The stomach is essentially clear by 3-3.5 h for all three drinks studied. The differentiation between liquids in current guidelines is not supported by this study.

Impact of white-tailed deer on the spread of Borrelia burgdorferi.

There is a public perception that the white-tailed deer Odocoileus virginianus (Artiodactyla: Cervidae) is the main reservoir supporting the maintenance and spread of the causative agent of Lyme disease, Borrelia burgdorferi. This study examines the pathogen prevalence rate of Borrelia in adult Ixodes scapularis (Ixodida: Ixodidae), the black-legged tick, collected from white-tailed deer and compares it with pathogen prevalence rates in adult ticks gathered by dragging vegetation in two contiguous counties west of the Hudson Valley in upstate New York. In both Broome and Chenango Counties, attached and unattached ticks harvested from white-tailed deer had significantly lower prevalences of B. burgdorferi than those collected from vegetation. No attached ticks on deer (n = 148) in either county, and only 2.4 and 7.3% of unattached ticks (n = 389) in Broome and Chenango Counties, respectively, were harbouring the pathogen. This contrasts with the finding that 40.8% of ticks in Broome County and 46.8% of ticks in Chenango County collected from vegetation harboured the pathogen. These data suggest that a mechanism in white-tailed deer may aid in clearing the pathogen from attached deer ticks, although white-tailed deer do contribute to the spatial distribution of deer tick populations and also serve as deadend host breeding sites for ticks.

Small, Smart, Fast, and Cheap: Microchip-Based Sensors to Estimate Air Pollution Exposures in Rural Households.

Over the last 20 years, the Kirk R. Smith research group at the University of California Berkeley-in collaboration with Electronically Monitored Ecosystems, Berkeley Air Monitoring Group, and other academic institutions-has developed a suite of relatively inexpensive, rugged, battery-operated, microchip-based devices to quantify parameters related to household air pollution. These devices include two generations of particle monitors; data-logging temperature sensors to assess time of use of household energy devices; a time-activity monitoring system using ultrasound; and a CO2-based tracer-decay system to assess ventilation rates. Development of each system involved numerous iterations of custom hardware, software, and data processing and visualization routines along with both lab and field validation. The devices have been used in hundreds of studies globally and have greatly enhanced our understanding of heterogeneous household air pollution (HAP) concentrations and exposures and factors influencing them.

The Community Compass Project: A Community Engagement Model Targeting African-Americans in the Low Country of South Carolina.

Despite cutting edge progress in early detection, risk reduction, and prevention, unique contextual and sociocultural factors contribute to higher mortality rates for selected cancers in African-American men and women. Collaborative community engagement and outreach programming strategies that focus on sustainability and grass-roots organizing can inform health risk disparities, build trust, and allow communities to take ownership of their own health needs. This paper describes a successful evidence-based community engagement intervention woven into the social and interpersonal fabric of the African-American community in Charleston, South Carolina. Through the creation of a coalition of community partners that included the state's only National Cancer Institute designated cancer center, collaboratively developed platforms devoted to population-specific preventive interventions for cancer and obesity education, awareness, and research initiatives were implemented within the identified community.

Randomized controlled trial comparing impact on platelet reactivity of twice-daily with once-daily aspirin in people with Type 2 diabetes.

AIMS: Reduced aspirin efficacy has been demonstrated in people with Type 2 diabetes. Because increased platelet reactivity and/or turnover are postulated mechanisms, we examined whether higher and/or more frequent aspirin dosing might reduce platelet reactivity more effectively. METHODS: Participants with Type 2 diabetes (n = 24) but without known cardiovascular disease were randomized in a three-way crossover design to 2-week treatment periods with aspirin 100 mg once daily, 200 mg once daily or 100 mg twice daily. The primary outcome was platelet reactivity, assessed using the VerifyNow(™) ASA method. Relationships between platelet reactivity and aspirin dosing were examined using generalized linear mixed models with random subject effects. RESULTS: Platelet reactivity decreased from baseline with all doses of aspirin. Modelled platelet reactivity was more effectively reduced with aspirin 100 mg twice daily vs. 100 mg once daily, but not vs. 200 mg once daily. Aspirin 200 mg once daily did not differ from 100 mg once daily. Aspirin 100 mg twice daily was also more effective than once daily as measured by collagen/epinephrine-stimulated platelet aggregation and urinary thromboxane levels, with a similar trend measured by serum thromboxane levels. No episodes of bleeding occurred. CONCLUSIONS: In Type 2 diabetes, aspirin 100 mg twice daily reduced platelet reactivity more effectively than 100 mg once daily, and numerically more than 200 mg once daily. Clinical outcome trials evaluating primary cardiovascular disease prevention with aspirin in Type 2 diabetes may need to consider using a more frequent dosing schedule.

Stretchable liquid-crystal blue-phase gels.

Liquid-crystalline polymers are materials of considerable scientific interest and technological value. An important subset of these materials exhibit rubber-like elasticity, combining the optical properties of liquid crystals with the mechanical properties of rubber. Moreover, they exhibit behaviour not seen in either type of material independently, and many of their properties depend crucially on the particular mesophase employed. Such stretchable liquid-crystalline polymers have previously been demonstrated in the nematic, chiral-nematic, and smectic mesophases. Here, we report the fabrication of a stretchable gel of blue phase I, which forms a self-assembled, three-dimensional photonic crystal that remains electro-optically switchable under a moderate applied voltage, and whose optical properties can be manipulated by an applied strain. We also find that, unlike its undistorted counterpart, a mechanically deformed blue phase exhibits a Pockels electro-optic effect, which sets out new theoretical challenges and possibilities for low-voltage electro-optic devices.

Causes of Death of Transgender and Gender Diverse Veterans.

INTRODUCTION: Transgender and gender diverse (TGD) veterans face numerous challenges due to stigma and marginalization, which have a significant impact on their health and well-being. However, there is insufficient data on cause-specific mortality in TGD veteran populations in the U.S. The purpose of this study was to describe the leading causes of death in a sample of TGD veterans who received care from the Veterans Health Administration. METHODS: A secondary data analysis was conducted using Veterans Health Administration electronic health record data matched with death certificate records from the National Death Index from October 1, 1999 to December 31, 2019. Using record axis codes from National Death Index data, the 25 most frequent underlying and all causes of death were summarized. RESULTS: Deaths occurred in 1,415 TGD veterans. Ranking by any mention on the death certificate, mental and behavioral disorders due to psychoactive substance use (17.2%), conduction disorders and cardiac dysrhythmias (15.3%), chronic obstructive pulmonary disease (15.1%), diabetes mellitus (13.9%), and chronic ischemic heart disease (13.3%) were the top five causes of death. Three distinct methods of suicide appeared as the 7th (firearms), 17th (self-poisoning), and 24th (hanging) underlying causes of death for TGD veterans. CONCLUSIONS: Targeted prevention efforts or interventions to reduce the frequency and severity of causes of death, particularly mental and behavioral health disorders and metabolic disorders, could prevent premature mortality among TGD adults.
