General self-efficacy as a mediator of the association between adverse childhood experiences and psychological distress in gender-minority individuals.

PURPOSE: To investigate the mediating role of general self-efficacy (i.e., belief in one's competence to cope with a broad range of stressful or challenging demands) in the relationship between adverse childhood experiences (ACEs) and psychological distress (i.e., symptoms of stress, anxiety and depression) in gender minority individuals, which include people with a gender identity that is not aligned with their sex assigned at birth. DESIGN AND METHODS: The study sample included gender minority participants who participated in Waves 4 and 5 of Project AFFIRM, a multi-site longitudinal study of gender minority health. ACEs, general self-efficacy, and psychological distress were measured using the Behavior Risk Factor Surveillance System ACE Module at Wave 4, the PROMIS General self-efficacy measure at Wave 4, and the Brief Symptoms Inventory Global Severity Index (GSI) at Wave 5, respectively. After adjustment for covariates, including age, race, sex assigned at birth, and income, multivariable linear regression analyses were conducted to assess each component of the proposed mediation model. Next, mediation analyses were used to determine whether general self-efficacy mediated the association between ACEs and psychological distress. FINDINGS: The sample for this study consisted of 166 gender minority adults with a mean age of 38.6 ± 12.2 years. Most were non-Hispanic White (46.4%) and female assigned at birth (59.6%). Mean ACEs score was 3.2 ± 2.1 (range 0-8), mean general self-efficacy score was 13.9 ± 3.6 (range 4-20), and mean raw-score GSI was 17.3 ± 13.7 (range 0-64). Participants who reported experiencing more ACEs had greater psychological distress (B 1.60; 95% CI = 0.66, 2.54) and lower general self-efficacy (B -0.41; 95% CI = -0.67, -0.15). In addition, lower general self-efficacy was associated with higher psychological distress (B -1.06; 95% CI = -1.61, -0.51). Bootstrap estimation of the indirect effect was significant (95% CI = 0.14, 0.90) and explained 27.1% (95% CI = 7.76, 69.76) of the total effect of ACEs on psychological distress in gender minority adults. CONCLUSIONS: Our findings suggest that general self-efficacy partially mediated the positive association between ACEs and psychological distress in gender minority adults. Interventions that aim to improve general self-efficacy may be beneficial in alleviating psychological distress in gender minority adults. CLINICAL RELEVANCE: Nurses can play an important role in reducing the health risks associated with ACEs by screening gender minority individuals using a trauma-informed approach to care and offering resources and referrals, as appropriate.

Sleep and Circadian Disturbance in Cardiovascular Risk.

PURPOSE OF REVIEW: We discuss the relationship between sleep and circadian factors with cardiovascular disease (CVD) risk, including physiologic, behavioral, and psychological mechanisms along this pathway. RECENT FINDINGS: The relationship between short and long sleep duration, as well as insomnia, with CVD risk is well-established. Recent work has highlighted how other sleep factors, such as sleep regularity (i.e., consistency of sleep timing), multidimensional sleep health, and circadian factors like chronotype and social jetlag, relate to CVD risk. Sleep-focused interventions (e.g., cognitive behavioral therapy for insomnia and sleep extension) may be effective to reduce CVD risk and disease burden. Sleep is increasingly recognized as an integral component of cardiovascular health. This was underscored by the recent inclusion of sleep duration as a health behavior in the American Heart Association's Life's Essential 8 for defining optimal cardiovascular health.

Fucoidan stimulates cell division in the amebocyte-producing organ of the schistosome-transmitting snail Biomphalaria glabrata.

Adult Salvador (schistosome-resistant) strain Biomphalaria glabrata snails were injected with 5 µl of 10 mg/ml solutions of the sulfated polysaccharides λ carageenan, dextran sulfate, fucoidan, and heparin, the nonsulfated polysaccharide laminarin, and the monosaccharides L-fucose and L-galactose, and mitotic activity in the amebocyte-producing organ (APO) was measured in histological sections at 24 h post injection. Among the substances tested, only fucoidan induced elevated mitotic activity. Desulfated fucoidan was not mitogenic, indicating that sulfate groups are required for activity. Schistosome-susceptible M-line snails possessed minimal or no hematopoietic tissue in their APO, which did not respond to fucoidan. Immersion of juvenile Salvador snails in 1 or 10 mg/ml solutions of fucoidan for 3 h did not elevate mitotic activity at 24 h post immersion, suggesting that the external and digestive tract epithelia of B. glabrata are impermeable to this molecule. These results provide support for the hypothesis that fucosylated glycans on the tegument and in excretory-secretory products of sporocysts of Schistosoma mansoni are in part responsible for increased mitotic activity in the APO of B. glabrata infected with this trematode or injected with its extracts.

Day-to-day associations of intersectional minority stressors with sleep health in sexual and gender minority people of color.

OBJECTIVE: To determine the day-to-day associations between minority stressors (i.e., anticipated and experienced discrimination) and sleep health outcomes (i.e., total sleep time (TST), sleep disturbances, and sleep-related impairment) among sexual and gender minority (SGM) people of color. METHOD: An online sample of SGM people of color living in the United States participated in a 30-day daily diary study. Daily anticipated and experienced discrimination as well as subjective sleep outcomes were assessed via electronic diaries using validated measures. Wrist-worn actigraphy was used to objectively assess TST. Multilevel linear models (MLMs) were used to estimate the independent associations of daily intersectional minority stressors with subsequent sleep outcomes, adjusted for demographic factors and lifetime discrimination. RESULTS: The sample included 43 SGM people of color with a mean age of 27.0 years (± 7.7) of which 84% were Latinx, 47% were multiracial, and 37% were bisexual. Results of MLMs indicated that greater report of daily experienced discrimination was positively associated with same-night sleep disturbances, B (SE) = 0.45 (0.10), p < .001. Daily anticipated discrimination was positively associated with sleep-related impairment on the following day, B (SE) = 0.77 (0.17), p < .001. However, daily anticipated and experienced discrimination were not associated with same-night TST. CONCLUSIONS: Findings highlight the importance of considering the differential effects of daily intersectional minority stressors on the sleep health of SGM people of color. Further research is needed to identify factors driving the link between daily minority stressors and sleep outcomes to inform sleep health interventions tailored to this population.

Structural stigma and alcohol use among sexual and gender minority adults: A systematic review.

Background: Sexual and gender minority (SGM) people are more likely than their cisgender, heterosexual counterparts to report negative alcohol-related outcomes. Although the association between individual- and interpersonal-level minority stressors and negative alcohol-related outcomes among SGM people is well-established, structural-level minority stressors are understudied. This systematic review examined structural-level stigma and alcohol-related outcomes among SGM people to inform future research, interventions, and policy. Methods: We used five electronic databases to search for studies published between January 2010 and May 2022 that examined associations between structural stigma and alcohol use among SGM adults in the United States. Peer-reviewed, quantitative studies available in English were included. We conducted quality appraisal using the Joanna Briggs Institute checklist. Results: The final sample included 11 studies. Overall, there was moderate to strong support for a positive association between structural stigma and negative alcohol-related outcomes among SGM people, with differences by gender, sexual identity, race, and ethnicity. All studies used cross-sectional designs, and nearly half utilized non-probability samples. Transgender and nonbinary people, SGM people of color, and sexual identity subgroups beyond gay, lesbian, and heterosexual were underrepresented. Structural stigma was most commonly measured as a state-level index. Alcohol measures were heterogeneous. Multilevel stigma and resiliency factors were understudied. Conclusions: Addressing structural stigma is critical in reducing negative alcohol-related outcomes and inequities among SGM people. Research is needed that includes probability samples, longitudinal designs, and samples that reflect the diversity of SGM people. Future studies should examine the influence of multilevel stigma and resiliency factors on alcohol-related outcomes.

Examining the role of problematic drug use in the relationship between discrimination and sleep disturbance in transgender and nonbinary individuals.

OBJECTIVE: Transgender and nonbinary (TGNB) individuals are a health disparity population at high risk for sleep disturbance (e.g., insomnia). Recent evidence suggests minority stress (e.g., discrimination) is associated with sleep disturbance in TGNB adults. However, investigators have yet to identify factors that might explain this relationship. In this study, we investigated the role of problematic drug use (PDU) in the relationship between discrimination and sleep disturbance in TGNB individuals. METHODS: The study sample included 194 TGNB participants from Wave 5 (2021) of Project AFFIRM, a multi-site longitudinal study of transgender health. Discrimination, PDU, and sleep disturbance were measured using the Everyday Discrimination Scale, Drug Use Disorders Identification Test (DUDIT), and PROMIS Sleep Disturbance measures, respectively. Individuals were classified as having PDU using established DUDIT criteria that were applied based on sex assigned at birth. Regression analyses were used to estimate the associations of study variables, and subsequently, mediation analysis was used to determine whether PDU partially mediated the association between discrimination and sleep disturbance. RESULTS: Nearly half of participants reported PDU, of which 83.2% reported cannabis use. Higher levels of discrimination were associated with worse self-reported sleep disturbance scores. Additionally, participants with greater discrimination were more likely to have PDU. Surprisingly, participants with PDU had lower sleep disturbance scores. CONCLUSIONS: Our cross-sectional findings suggest that PDU partially suppressed the association between discrimination and sleep disturbance in TGNB people. Efforts to address PDU in TGNB adults may consider assessing sleep disturbance as a motivating factor for drug use and the potential role of discrimination in perpetuating PDU.

Examining the associations of gender minority stressors with sleep health in gender minority individuals.

OBJECTIVES: Investigate the associations of gender minority stressors (including stigma consciousness [SC] and gender-related discrimination [GRD]) with sleep health in gender minority individuals. DESIGN: Cohort. PARTICIPANTS: 279 gender minority individuals. MEASUREMENTS: SC and GRD were measured using the Stigma Consciousness and Everyday Discrimination scales, respectively. Sleep disturbance was assessed using the PROMIS Sleep Disturbance measure. Subjective short sleep duration (<7 hours) was assessed. We used k-means longitudinal clustering to identify minority stress clusters (including SC and GRD scores). Linear and logistic regression models were used to examine the associations of these clusters with sleep disturbance and sleep duration, respectively, adjusted for demographic characteristics. RESULTS: Mean age was 36.9 ± 13.6 years; most were non-White (54.5%), 52.5% were transmasculine, and 22.6% were heterosexual. Mean sleep disturbance score was 17.2 ± 6.1 (range 6-30) and 52% reported short sleep duration. We identified 3 minority stress clusters. Compared to participants with low SC/low GRD, those with high SC/low GRD (B 3.33, 95% confidence interval [CI] = 1.64, 5.01) and high SC/high GRD (B 4.51, 95% CI = 2.63, 6.39) had worse sleep disturbance scores. Participants in the high SC/high GRD cluster were more likely to report short sleep duration relative to the low SC/low GRD cluster (adjusted odds ratios 2.17; 95% CI = 1.11-4.26). CONCLUSIONS: Participants with both high SC and high GRD had worse sleep health. Future longitudinal studies should examine factors that drive the link between gender minority stress and sleep health in gender minority individuals to inform sleep health interventions tailored for this population.

Understanding the Impact of the COVID-19 Pandemic on the Mental Health of Transgender and Gender Nonbinary Individuals Engaged in a Longitudinal Cohort Study.

While the COVID-19 pandemic in the United States disproportionately impacts marginalized communities, no empiric US-based research has focused specifically on transgender and gender nonbinary (TGNB) people. We examined the pandemic's impact on an established longitudinal cohort of TGNB individuals (N = 208) by administering an online survey between March-June 2020. We used multivariable linear regression to examine reduced LGBTQ/TGNB community support and disruptions in gender-affirming health care as predictors of psychological distress during the pandemic. We found that the pandemic exacerbated ongoing mental health disparities for TGNB individuals. Furthermore, reduced LGBTQ/TGNB support was associated with increased psychological distress during the pandemic. Interruption and/or delay in gender-affirming health care was not associated with increased psychological distress during the pandemic. Special attention is needed to address the unique ways in which TGNB individuals were affected by the COVID-19 pandemic. This includes increasing access to LGBTQ/TGNB community support and addressing long-standing health disparities.

Activation of an innate immune response in the schistosome-transmitting snail Biomphalaria glabrata by specific bacterial PAMPs.

Injection of crude lipopolysaccharide (LPS) from Escherichia coli into the hemocoel of Biomphalaria glabrata stimulates cell proliferation in the amebocyte-producing organ (APO). However, it is not known if mitogenic activity resides in the lipid A or O-polysaccharide component of LPS. Moreover, the possible role of substances that commonly contaminate crude LPS and that are known to stimulate innate immune responses in mammals, e.g., peptidoglycan (PGN), protein, or bacterial DNA, is unclear. Therefore, we tested the effects of the following injected substances on the snail APO: crude LPS, ultrapurified LPS (lacking lipoprotein contamination), two forms of lipid A, (diphosphoryl lipid A and Kdo2-lipid A), O-polysaccharide, Gram negative PGN, both crude and ultrapurified (with and without endotoxin activity, respectively), Gram positive PGN, PGN components Tri-DAP and muramyl dipeptide, and bacterial DNA. Whereas crude LPS, ultrapurified LPS, and crude PGN were mitogenic, ultrapurified PGN was not. Moreover, LPS components, PGN components, and bacterial DNA were inactive. These results suggest that it is the intact LPS molecule which stimulates cell division in the APO.
