RESUMO
The immigrant population in the United States (U.S.) is rapidly growing; yet there is limited knowledge about how reasons for migrating to the U.S. are associated with HIV prevention behaviors. Using data from the American Men's Internet Survey (2018-2020), we performed a Latent Class Analysis (LCA) to identify patterns in reasons for migration among cisgender gay, bisexual, and other sexual minority men (SMM) who born outside the U.S. We used multivariable logistic regression controlling for demographic characteristics to assess class associations with the following in the past 12 months: condomless anal sex (CAS), illicit drug use, marijuana use, HIV testing, and PrEP use. LCA identified six distinct patterns in reasons for migration among the sample (n = 1,657): (1) Family and friends (14%); (2) Financial (17%); (3) Personal freedom related to being gay (10%); (4) Pursuit of opportunities while living openly as SMM (12%); (5) Educational purposes (18%); (6) Not my decision (29%). While HIV testing (range = 57.6-65.4%) and PrEP use (range = 15.6-21.4%) did not vary by class (p > .05 for all), CAS and illicit drug use were significantly different (p < .05). SMM who migrated to pursue opportunities while living openly and whose reasons were not their decision had greater odds of CAS than SMM who migrated for educational purposes (aOR:1.72, 95% confidence interval [95%CI]:1.15-2.59; 1.57, 1.13-2.19, respectively). Reasons for migration among SMM were associated with behaviors that can increase HIV risk, but not testing or PrEP. Push and pull factors related to migration should be considered when developing behavioral HIV interventions for immigrant SMM.
RESUMEN: La población inmigrante en los Estados Unidos (EE. UU.) está creciendo rápidamente; sin embargo, hay un conocimiento limitado acerca de cómo las razones para migrar a los EE. UU. se asocian con comportamientos de prevención del VIH. Utilizando datos del American Men's Internet Survey (20182020), realizamos un Análisis de Clases Latentes (ACL) para identificar patrones en las razones de migración entre hombres cisgénero gays, bisexuales y otros hombres de minorías sexuales (HMS) que reportaron haber nacido fuera de los EE. UU. Utilizamos regresión logística multivariable controlando las características demográficas para evaluar las asociaciones de clases con los siguientes comportamientos en los últimos 12 meses: sexo anal sin condón (SAC), consumo de drogas ilícitas, uso de marihuana, prueba del VIH y uso de PrEP. El ACL identificó seis patrones distintos en las razones de migración en la muestra (n = 1,657): (1) Familia y amigos (14%); (2) Motivos financieros (17%); (3) Libertad personal relacionada con ser gay (10%); (4) Búsqueda de oportunidades mientras viven abiertamente como HMS (12%); (5) Propósitos educativos (18%); (6) No fue decisión propia (29%). Mientras que las pruebas del VIH (rango = 57.665.4%) y el uso de PrEP (rango = 15.621.4%) no variaron según la clase (p > .05 para todos), el SAC y el consumo de drogas ilícitas fueron significativamente diferentes (p < .05). Los HMS que emigraron para perseguir oportunidades mientras vivían abiertamente, y aquellos cuyas razones no fueron decisión propia, tuvieron mayores probabilidades de tener SAC que los HMS que emigraron con propósitos educativos (razón de probabilidades ajustada [aOR]: 1.72, intervalo de confianza del 95% [IC 95%]: 1.152.59; 1.57, 1.132.19, respectivamente). Las razones de migración a los EE. UU. entre los HMS estuvieron asociadas con comportamientos que pueden aumentar el riesgo de VIH, pero no con pruebas o PrEP. Los factores que impulsan y atraen relacionados con la migración deben considerarse al desarrollar intervenciones de prevención del VIH para HMS inmigrantes.

While pre-exposure prophylaxis (PrEP) has demonstrated efficacy in preventing HIV transmission, disparities in access persist in the United States, especially among Hispanic/Latinx sexual minority men (SMM). Language barriers and differences in how Latinx SMM obtain information may impact access to PrEP and HIV prevention. This study used data from the 2021 American Men's Internet Survey (AMIS) to examine differences in communication networks and PrEP use among Latinx SMM by primary language (Spanish vs. English). We examined the associations between Latinx SMM's individual- and meso-level communication networks and PrEP-related outcomes using modified Poisson regression with robust variances. Spanish-speaking Latinx SMM in the study were less likely to test for HIV, be aware of PrEP, and use daily PrEP, compared to English-speaking participants. Sexuality disclosure to a healthcare provider was positively associated with PrEP uptake among all participants and predicted STI testing over the past 12 months among English-speaking Latinx SMM. Findings highlight disparities in PrEP awareness and uptake among Latinx SMM, especially among those whose primary language is Spanish. Addressing these disparities through targeted interventions, including improved communication with healthcare providers, may help facilitate PrEP access and use in this population.

BACKGROUND AND OBJECTIVES: Poor oral health disproportionately affects low-income older adults, for whom food insecurity and poor mental health may affect dental health. We explored the associations between food insecurity, mental health, and dental health. Furthermore, we examined whether mental health impacted the associations between food insecurity and dental health. MATERIALS AND METHODS: We conducted a cross-sectional study with a convenience sample of 226 older adults (aged 50+), employing survey and dental screening data. Participants were recruited from seven community-based organisations in Washington State, USA. We calculated descriptive statistics and conducted Chi-square tests, t tests, and logistic regression analyses to assess the associations between aspects of dental health (untreated decay, gum disease, and unmet dental needs), mental health (depression and cognitive function), and food insecurity. RESULTS: In our sample, food insecurity was observed in 28.4%, 40.6% had untreated decay, 31.6% gum disease, and 42.5% unmet dental needs. Food insecurity was associated with a higher occurrence of untreated decay and unmet dental needs. Participants experiencing food insecurity had higher odds of gum disease (aOR = 2.3; 95% CI: 1.1, 5.2) and unmet dental needs (aOR = 3.2; 95% CI:1.4, 7.6). Greater gum disease due to food insecurity was observed among individuals with lower levels of cognitive impairment. CONCLUSION: Food insecurity is associated with poorer oral health among older adults and cognitive function may modify this relationship. These findings underscore the importance of addressing both food insecurity and cognitive impairment as integral components of efforts to improve the oral health of older adults.
RESUMO
BACKGROUND: Air pollution-induced systemic inflammation and oxidative stress are hypothesized to be the major biological mechanisms underlying pathological outcomes. We examined the association between short-term exposure to ambient air pollutants and biomarkers of inflammation and oxidative stress in 2199 general middle-aged Korean population residing in metropolitan areas. METHODS: Serum levels of inflammatory cytokines (interleukin [IL]-1ß, IL-6, IL-8, IL-10, and tumor necrosis factor [TNF]-α) and urinary levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG) were measured. Daily concentrations of a series of air pollutants (particulate matter [PM]10, PM2.5, SO2, NO2, CO, and O3) were predicted using the Community Multiscale Air Quality modeling system, and participant-level pollutant exposure was determined using geocoded residential addresses. Short-term exposure was defined as the 1- to 7-day moving averages. RESULTS: The multivariable-adjusted linear models controlling for the sociodemographic, lifestyle, temporal, and meteorological factors identified positive associations of PM with IL-1ß, IL-8, IL-10, TNF-α, and 8-OHdG levels; SO2 with IL-10 levels, CO with IL-1ß, IL-10, and TNF-α levels; and O3 with IL-1ß, IL-8, and 8-OHdG levels. O3 levels were inversely associated with IL-10 levels. For each pollutant, the strongest associations were observed for the 7-day average PM and CO with IL-1ß (per 10-µg/m3 increase in PM10: 2.7%, 95% confidence interval [CI] = 0.6-4.8; per 10-µg/m3 increase in PM2.5: 6.4%, 95% CI = 2.4-10.5; per 0.1-ppm increase in CO: 3.3%, 95% CI = 0.3-6.5); the 2-day average SO2 with IL-10 levels (per 1-ppb increase in SO2: 1.1%, 95% CI = 0.1-2.1); and the 7-day average O3 with IL-8 levels (per 1-ppb increase in O3: 1.3%, 95% CI = 0.7-1.9). CONCLUSIONS: Short-term exposure to ambient air pollutants may induce oxidative damage and pro-inflammatory roles, together with counter-regulatory anti-inflammatory response.

PURPOSE OF REVIEW: Although pre-exposure prophylaxis (PrEP) is effective for reducing risk of HIV transmission, stigma persists as a barrier to HIV prevention. Digital technologies present opportunities to access hard-to-reach populations and increase the efficiency of established interventions. This review examines current digital interventions addressing stigma to improve PrEP-related outcomes. RECENT FINDINGS: Digital technologies are increasingly used for HIV prevention and include a wide range of formats. Recent interventions focused on stigma and PrEP tend to engage mobile phone-related technology and focus on younger populations with particular attention to men who have sex with men and transgender women. Digital interventions that address stigma are promising for improving PrEP-related outcomes. No single technology currently demonstrates consistent superiority. Limited access to PrEP and heightened stigma in under-resourced countries present challenges for interventions supporting diverse communities. Further research should examine how digital interventions can reduce stigma beyond the individual level to enhance PrEP use and explore opportunities to improve and integrate approaches to stigma measurement.

Among the many effective prevention strategies, frequent HIV testing continues to be promoted to reduce the risk of HIV transmission among sexual minority men (SMM). Testing negative for HIV can result in varied reactions that influence subsequent HIV transmission behaviors, yet the extant research has primarily been conducted in English. The current study examined measurement invariance of a Spanish-translated Inventory of Reactions to Testing HIV Negative (IRTHN). The study also examined whether the IRTHN was associated with subsequent condomless anal sex. Data were drawn from 2,170 Latinx SMM subsample of the UNITE Cohort Study. We conducted a multigroup confirmatory factor analysis to test for measurement invariance between participants who opted to take the survey in English (n = 2,024) and those who opted to take it in Spanish (n = 128). We also examined if the IRTHN is associated with subsequent CAS. The results were suggestive of partial invariance. The subscales of Luck and Invulernability were associated with CAS at the 12-month follow-up. Practice and research-based implications are discussed.

Numerous mutations that impair retrograde membrane trafficking between endosomes and the Golgi apparatus lead to neurodegenerative diseases. For example, mutations in the endosomal retromer complex are implicated in Alzheimer's and Parkinson's diseases, and mutations of the Golgi-associated retrograde protein (GARP) complex cause progressive cerebello-cerebral atrophy type 2 (PCCA2). However, how these mutations cause neurodegeneration is unknown. GARP mutations in yeast, including one causing PCCA2, result in sphingolipid abnormalities and impaired cell growth that are corrected by treatment with myriocin, a sphingolipid synthesis inhibitor, suggesting that alterations in sphingolipid metabolism contribute to cell dysfunction and death. Here we tested this hypothesis in wobbler mice, a murine model with a homozygous partial loss-of-function mutation in Vps54 (GARP protein) that causes motor neuron disease. Cytotoxic sphingoid long-chain bases accumulated in embryonic fibroblasts and spinal cords from wobbler mice. Remarkably, chronic treatment of wobbler mice with myriocin markedly improved their wellness scores, grip strength, neuropathology, and survival. Proteomic analyses of wobbler fibroblasts revealed extensive missorting of lysosomal proteins, including sphingolipid catabolism enzymes, to the Golgi compartment, which may contribute to the sphingolipid abnormalities. Our findings establish that altered sphingolipid metabolism due to GARP mutations contributes to neurodegeneration and suggest that inhibiting sphingolipid synthesis might provide a useful strategy for treating these disorders.

INTRODUCTION: Food insecurity is an important social determinant of health, but there is limited understanding of its relationship with adult oral health. This study examined the associations between food insecurity and dental diseases (caries and periodontitis) among middle-aged and older adults in the United States and South Korea. METHODS: This study focused on middle-aged (40-59 years) and older adults (>59 years) who participated in the 2011-2016 US National Health and Nutrition Examination Surveys (NHANES) or the 2013-2015 South Korean NHANES. The exposure was food insecurity severity (food secure/early-stage food insecurity/middle-stage or severe food insecurity) assessed using the 18-item US Household Food Security Survey Module. The two outcomes were any untreated tooth decay and periodontitis measured using the Modified Community Periodontal Index of Treatment Needs. Covariate-adjusted odds ratios (OR) with 95% confidence intervals (CI) were generated using multivariable logistic regression models. RESULTS: Middle or severe food insecurity was associated with significantly higher odds of having untreated tooth decay than no food insecurity, but only among middle-aged adults in the United States (OR: 1.4, 95% CI 1.2, 1.9; P = .037) and Korea (OR = 1.8; 95% CI:1.0, 3.2; P = .036) and older adults in the United States (OR: 2.6, 95% CI 1.7, 4.0; P < .001). The associations between food insecurity and periodontitis were inconsistent across age group and country. CONCLUSION: Differing cultural norms and access to dental services in the United States and South Korea may influence the relationship between food insecurity and oral health. Future research should explore how addressing food insecurity could help to promote the oral health of middle-aged and older adults in diverse sociocultural contexts.

BACKGROUND: The THEMIS trial demonstrated that in high-risk patients with stable coronary artery disease and diabetes without previous myocardial infarction or stroke, ticagrelor, in addition to aspirin, reduced the incidence of ischemic events but increased major bleeding. Identification of patients who could derive the greatest net benefit from the addition of ticagrelor appears important. We used the CRUSADE bleeding risk score to risk stratify the THEMIS population. METHODS: The population was divided into tertiles: score ≤22, 23 to 33, and ≥34. In each tertile, primary efficacy (composite of cardiovascular death, myocardial infarction, or stroke) and safety (TIMI major bleeding) outcomes were analyzed. NACE (net adverse clinical events) was defined as the irreversible harm composite, in which all-cause death, myocardial infarction, stroke, amputations, fatal bleeds, and intracranial hemorrhage were counted. RESULTS: Patients in the lower risk tertile experienced fewer ischemic events with ticagrelor than placebo, whereas there was no significant benefit from ticagrelor in the other tertiles (Pinteraction = .008). Bleeding rates were consistently increased with ticagrelor across all tertiles (Pinteraction = .79). Ticagrelor reduced NACE in the first tertile (HR = 0.74, 95% CI = 0.61-0.90) but not in the others (HR = 1.03, 95% CI = 0.86-1.23 and HR = 1.05, 95% CI = 0.91-1.22, respectively; Pinteraction = .012). CONCLUSIONS: In patients with stable coronary artery disease and diabetes without a history of myocardial infarction or stroke, only those at the lower end of the bleeding risk spectrum according to the CRUSADE score derived net benefit from ticagrelor.

PURPOSE OF REVIEW: The elevated adverse cardiovascular event rate among patients with low high-density lipoprotein cholesterol (HDL-C) formed the basis for the hypothesis that elevating HDL-C would reduce those events. Attempts to raise endogenous HDL-C levels, however, have consistently failed to show improvements in cardiovascular outcomes. However, steady-state HDL-C concentration does not reflect the function of this complex family of particles. Indeed, HDL functions correlate only weakly with serum HDL-C concentration. Thus, the field has pivoted from simply raising the quantity of HDL-C to a focus on improving the putative anti-atherosclerotic functions of HDL particles. Such functions include the ability of HDL to promote the efflux of cholesterol from cholesterol-laden macrophages. Apolipoprotein A-I (apoA-I), the signature apoprotein of HDL, may facilitate the removal of cholesterol from atherosclerotic plaque, reduce the lesional lipid content and might thus stabilize vulnerable plaques, thereby reducing the risk of cardiac events. Infusion of preparations of apoA-I may improve cholesterol efflux capacity (CEC). This review summarizes the development of apoA-I therapies, compares their structural and functional properties and discusses the findings of previous studies including their limitations, and how CSL112, currently being tested in a phase III trial, may overcome these challenges. RECENT FINDINGS: Three major ApoA-I-based approaches (MDCO-216, CER-001, and CSL111/CSL112) have aimed to enhance reverse cholesterol transport. These three therapies differ considerably in both lipid and protein composition. MDCO-216 contains recombinant ApoA-I Milano, CER-001 contains recombinant wild-type human ApoA-I, and CSL111/CSL112 contains native ApoA-I isolated from human plasma. Two of the three agents studied to date (apoA-1 Milano and CER-001) have undergone evaluation by intravascular ultrasound imaging, a technique that gauges lesion volume well but does not assess other important variables that may relate to clinical outcomes. ApoA-1 Milano and CER-001 reduce lecithin-cholesterol acyltransferase (LCAT) activity, potentially impairing the function of HDL in reverse cholesterol transport. Furthermore, apoA-I Milano can compete with and alter the function of the recipient's endogenous apoA-I. In contrast to these agents, CSL112, a particle formulated using human plasma apoA-I and phosphatidylcholine, increases LCAT activity and does not lead to the malfunction of endogenous apoA-I. CSL112 robustly increases cholesterol efflux, promotes reverse cholesterol transport, and now is being tested in a phase III clinical trial. Phase II-b studies of MDCO-216 and CER-001 failed to produce a significant reduction in coronary plaque volume as assessed by IVUS. However, the investigation to determine whether the direct infusion of a reconstituted apoA-I reduces post-myocardial infarction coronary events is being tested using CSL112, which is dosed at a higher level than MDCO-216 and CER-001 and has more favorable pharmacodynamics.

Internet-based surveys can be programmed and advertised in multiple languages to reach non-English-speaking individuals, but it is unclear the extent to which this enhances the diversity of participants and supports inclusion of individuals at higher risk for HIV. We sought to examine how language of survey completion (English or Spanish) was associated with sociodemographic characteristics and indicators of HIV risk and prevention among cisgender Latino sexual minority men (SMM). We analyzed national and Washington State data using the Understanding New Infections through Targeted Epidemiology (UNITE) Cohort Study (2017 and 2018) and the Washington HIV/STI Prevention Project (WHSPP) survey (2017 and 2018/2019), respectively. Latino SMM who completed online surveys in Spanish differed from those who completed surveys in English across several sociodemographic characteristics including age, education, and income. After adjusting for sociodemographic characteristics and HIV-related risk factors, Spanish language respondents in UNITE were less likely to have tested for HIV in the past year, and those in WHSPP were more likely to report a recent STI diagnosis. Findings suggest that Latino SMM who complete surveys in Spanish comprise a unique subgroup that may have a specific HIV health and risk behavior profile. Our results suggest a need for increased and tailored efforts to recruit and include Spanish-speaking Latino SMM for local and national research and public health programming.
RESUMEN: Encuestas por internet pueden ser programadas y anunciadas para alcanzar a personas que no hablan inglés, pero no queda claro si esto pueda mejorar la diversidad de los participantes de investigación y apoyar la inclusión de los individuos de alto riesgo a infección con el VIH. En este estudio examinamos la relación del idioma de completar la encuesta en línea (inglés o español) entre hombres Latinos de minorías sexuales (HLMS) cisgénero con características sociodemográficas y determinantes para el riesgo y prevención del VIH. Analizamos los datos nacionales y estatales con el estudio de cohorte de Understanding New Infections through Targeted Epidemiology (UNITE) (2017 y 2018) y El Proyecto de Washington para la Prevención del VIH/Infecciones de Transmisión Sexual (WHSPP) (2017 y 2018/2019), respectivamente. Los HLSM quienes completaron las encuestas por internet en español fueron diferentes a los que completaron las encuestas en inglés por varias características sociodemográficas incluso la edad, la educación, y el ingreso. Después de ajustar por las características sociodemográficas y los factores de riesgo asociados con el VIH, los participantes de UNITE que respondieron en español tuvieron menos probabilidad de haberse hecho la prueba de VIH en el año pasado y los que participaron en el WHSPP eran más probable que reportaran un diagnóstico de ITS. Los resultados indican que los HLSM quienes completan las encuestas en español representan un subgrupo distinto que tiene un perfil específico de comportamiento de riesgo y salud respecto al VIH. Los resultados demuestran la necesidad de mayores esfuerzos especializados para reclutar e incluir los HLSM quienes hablan español para que participen en las investigaciones en línea a nivel local y nacional y la programación de la salud pública.

BACKGROUND: D-dimer, a marker of ongoing procoagulant activity, has been widely used for the diagnosis of venous thromboembolism (VTE). The prognostic significance of D-dimer in stratifying VTE risk for acutely ill medical patients has not been well-established. METHODS: A literature search was performed to collect studies that compared the incidence of short-term VTE between acutely ill medical patients with elevated or nonelevated D-dimer levels. The cutoff of D-dimer was 0.5 µg/mL or otherwise defined by included studies. The study endpoint was any occurrence of VTE (inclusive of deep vein thrombosis [DVT], pulmonary embolism, or VTE-related death) within 90 days of hospital presentation. A meta-analytic approach was employed to estimate the odds ratio (OR) with 95% CI by fitting random-effects models using the generic inverse variance weighted approach. RESULTS: A total of 10 studies representing 31,119 acutely ill medical patients were included. Compared to those with nonelevated D-dimer levels, patients with elevated D-dimer had approximately threefold greater odds for short-term VTE within 90 days (OR, 3.28; 95% CI, 2.44 to 4.40; p < 0.0001). The association of elevated D-dimer with VTE composite (OR, 3.33; 95% CI, 2.20 to 5.02) and with DVT (OR, 3.26; 95% CI, 2.32 to 4.58) was comparable. The association was significant among patients who presented various acute medical illness (OR, 2.68; 95% CI, 2.01 to 3.58) and those who presented with acute stroke (OR, 3.25; 95% CI, 2.31 to 4.58). CONCLUSION: Elevation of D-dimer was predictive of the occurrence of VTE within 90 days among acutely ill medical patients.

OBJECTIVE: eHealth has growing potential to enhance access to HIV prevention for hard to reach populations, including young Latino immigrant men who have sex with men (MSM) in the United States. We examined the feasibility and acceptability of using eHealth tools, specifically social media platforms, to facilitate HIV testing and pre-exposure prophylaxis (PrEP) uptake among this population. DESIGN: We utilized a community sensitive approach to conduct 30 in-depth interviews and five focus groups with young Latino immigrant MSM in Seattle, WA. Data were analyzed using thematic analysis with both data-driven inductive and a priori deductive approaches. RESULTS: Participants were open to receiving HIV information via social media platforms. Participants recommended that social media content be tailored with their language preferences, cultural norms, and beliefs about HIV testing and PrEP in mind. Further, participants emphasized that content avoid stigmatizing HIV or Latino MSM's complex identities. CONCLUSIONS: Results have implications for utilizing social media platforms and developing HIV prevention interventions for Latino immigrant MSM. Findings highlight that HIV prevention content should acknowledge how identities as an emerging adult, Latino, immigrant, and MSM, warrant unique consideration.

OBJECTIVES: Adolescents' exposure to violence between parents acts as a precursor to risky behaviors; however, empirical studies that examined the potential pathways from exposure to violence between parents to risky behaviors are rare. Consequently, the prevention and intervention strategies for risky sexual activities are limited without the identification of malleable mediators. METHODS: Mediators on the association between adolescent exposure to parental fighting and risky sexual activities are examined, which include internalizing behaviors, running away from home, and affiliation with risky peers. Relationships between these variables are examined for males and females separately. The sample consists of 673 adolescents in a neighborhood located in Chicago's Southside who completed a survey. RESULTS: Exposure to parental fighting was not directly associated with risky sexual activities for either males or females. However, among females, exposure to parental fighting was significantly and positively related to internalizing behaviors and running away from home, and internalizing behaviors were also positively associated with running away from home. For males, however, only the association between internalizing behaviors and running away from home was found to be significant. Further, the relationship between exposure to parental fighting and risky sexual activities was mediated by running away from home. CONCLUSIONS: Targeted strategies for prevention are critical for improving sexual health outcomes among adolescents in low-resourced urban neighborhoods.

Several studies have demonstrated the usefulness of cardiac troponin I (cTn) levels in predicting adverse clinical outcomes of patients with anerusmal subarachnoid hemorrhage (aSAH). However, it remains unclear whether cTn levels can be a useful factor in predicting adverse neurologic and cardiovascular outcomes regarding follow-up duration. The study aimed to evaluate the clinical value of cTn elevation among patients with aSAH. A systematic literature search was performed in PubMed and Cochrane to collect original studies that compared the adverse outcomes in patients with aSAH who had elevated cTn levels and those who did not have elevated cTn levels. Data on patient demographics and outcome measurements (mortality, major disability, delayed cerebral ischemia, cardiac dysfunction, and pulmonary edema) were extracted. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were computed by fitting a random effects model. A total of 4,117 patients with aSAH were included in the meta-analysis. Elevated cTn levels was associated with a higher all-cause mortality (OR 3.64; 95% CI 2.68-4.94; I2 = 22.05%), poor major disability (OR 2.27; 95% CI 1.5-3.37; I2 = 52.07%), delayed cerebral ischemia (OR 2.10; 95% CI 1.46-3.03; I2 = 13.80%), cardiac dysfunction (OR 9.20; 95% CI 4.31-19.60; I2 = 39.89), and pulmonary edema (OR 10.32; 95% CI 5.64-18.90; I2 = 0.00%). Additionally, elevated cTn levels was associated with higher mortality in prospective studies (OR 3.66; 95% CI 2.61-5.14) as well as when compared with studies with short-term and long-term follow-up periods. Patients with aSAH who had elevated cTn levels also tended to experience poor short-term major disability (OR 2.36; 95% CI 1.48-3.76). Among patients with aSAH, elevated cTn levels was associated with higher mortality and adverse neurologic and cardiovascular outcomes. Given its clinical value, cardiac troponin levels may be included in the assessment of patients withs aSAH.

Perceptions of alcohol and other drug (AOD) use, harm reduction, and culture were examined among 10 U.S. Indigenous youth 13-17 years of age. Key findings were contextualized within the four constructs of Indigenous relationality: (a) youth understand the harms of AOD use (people); (b) youth appreciate non-abstinence-based education (ideas); (c) youth need safe spaces to talk about the impacts of AOD use (place); and (d) youth desire to help prevent AOD harms for themselves and others (cosmos). Findings from this community-based participatory study serve as the theoretical foundation to support the development of an Indigenous youth harm reduction intervention to prevent AOD use and related harms among urban Indigenous youth in the Pacific Northwest.
RESUMO
Emerging evidence has underscored the potential usefulness of red blood cell distribution width (RDW) measurement in predicting the mortality and disease severity of COVID-19. This study aimed to assess the association of the plasma RDW levels with adverse prognosis in COVID-19 patients. A comprehensive literature search from inception to September 2020 was performed to harvest original studies reporting RDW on admission and clinical outcomes among patients hospitalized with COVID-19. RDW levels were compared between cases (patients who died or developed more severe symptoms) and controls (patients who survived or developed less severe symptoms). A total of 14,866 subjects from 10 studies were included in the meta-analysis. Higher levels of RDW were associated with adverse outcomes in COVID-19 patients (mean differences = 0.72; 95% CI = 0.47-0.97; I2 = 89.51%). Deceased patients had higher levels of RDW compared to patients who survived (mean differences = 0.93; 95% CI = 0.63-1.23; I2 = 85.58%). Severely ill COVID-19 patients showed higher levels of RDW, as opposed to patients classified to have milder symptoms (mean differences = 0.61; 95% CI = 0.28-0.94; I2 = 82.18%). Elevated RDW levels were associated with adverse outcomes in COVID-19 patients. This finding warrants further research on whether RDW could be utilized as a simple and reliable biomarker for predicting COVID-19 severity and whether RDW is mechanistically linked with COVID-19 pathophysiology.

Chloroquine or its derivative hydroxychloroquine (HCQ) combined with or without azithromycin (AZ) have been widely investigated in observational studies as a treatment option for coronavirus 2019 (COVID-19) infection. The network meta-analysis aims to summarize evidence from randomized controlled trials (RCTs) to determine if AZ or HCQ is associated with improved clinical outcomes. PubMed and Embase were searched from inception to March 7, 2021. We included published RCTs that investigated the efficacy of AZ, HCQ, or its combination among hospitalized patients with COVID-19 infection. The outcomes of interest were all-cause mortality and the use of mechanical ventilation. The pooled odds ratio was calculated using a random-effect model. A total of 10 RCTs were analyzed. Participant's mean age ranged from 40.4 to 66.5 years. There was no significant effect on mortality associated with AZ plus HCQ (odds ratio [OR] = 0.562 [95% confidence interval {CI}: 0.168-1.887]), AZ alone (OR = 0.965 [95% CI: 0.865-1.077]), or HCQ alone (OR = 1.122 [95% CI: 0.995-1.266]; p = 0.06). Similarly, based on pooled effect sizes derived from direct and indirect evidence, none of the treatments had a significant benefit in decreasing the use of mechanical ventilation. No heterogeneity was identified (Cochran's Q = 1.68; p = 0.95; τ2 = 0; I2 = 0% [95% CI: 0%-0%]). Evidence from RCTs suggests that AZ with or without HCQ was not associated with a significant effect on the mortality or mechanical ventilation rates in hospitalized patients with COVID-19. More research is needed to explore therapeutics agents that can effectively reduce the mortality or severity of COVID-19.

Posttraumatic stress, low academic performance, and future orientation as pathways from community violence exposure to sexual risk-taking behavior were examined among 753 African American youth in a large urban school district, ranging from ages of 13 to 24 years. Youth completed a self-report instrument. Youth completed a self-report instrument of Exposure to Violence Probe, University of California at Los Angeles' PTSD Reaction Index Adolescent Version, and Coopersmith's Self-Esteem Scale. Structural equation modeling was performed to examine relationships among the major study variables. Results indicated that community violence exposure was not directly associated with sexual risk behavior. However, community violence exposure had a significantly positive impact on posttraumatic stress, which was associated with low future orientation and sexual risk behavior. Findings suggest that targeted interventions need to consider variables that mediate the association between violence exposure and sexual risk behavior, which can reduce poor sexual health outcomes among urban youth who are exposed to violence in their community.

Men who have sex with men (MSM) are disproportionately affected by HIV and may avoid disclosing their sexual preferences to others. With heightened attention on immigrant status in the United States, foreign-born MSM may be particularly concerned about disclosing their sexual orientation. We sought to examine how immigrant status is associated with sexual orientation disclosure among MSM and to assess the impact of disclosure on HIV/STD prevention outcomes stratified by nativity. We analyzed data from the 2014 and 2017 Seattle-area surveys of MSM from the National HIV Behavioral Surveillance (NHBS) system. Foreign-born MSM were less likely than U.S.-born MSM to have disclosed their sexuality to friends who are not gay, lesbian, or bisexual (85.0% vs. 95.5%; p < .001) or to family members (80.5% vs. 91.3%; p < .001). Further, disclosure to one's health care provider significantly increased the likelihood of having tested for HIV in the past 12 months among foreign-born and U.S.-born MSM. Findings highlight the need to better understand the risks and benefits of disclosure among foreign-born MSM. Future research may explore how responses and reactions to disclosure among foreign-born MSM shape pathways to HIV risk and prevention.
