RESUMO

INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic disrupted U.S. Military operations and potentially compounded the risk for adverse mental health outcomes by layering unique occupational stress on top of general restrictions, fears, and concerns. The objective of the current study was to characterize the prevalence of COVID-19 concerns and information needs, demographic disparities in these outcomes, and the degree to which COVID-19 concerns and information needs were associated with heightened risk for adverse mental health outcomes among U.S. Army soldiers. MATERIALS AND METHODS: Command-directed anonymous surveys were administered electronically to U.S. soldiers assigned to one of three regional commands in the Northwest United States, Europe, and Asia-Pacific Region. Surveys were administered in May to June 2020 to complete (time 1: n = 21,294) and again in December 2020 to January 2021 (time 2: n = 10,861). Only active duty or active reservists/national guard were eligible to participate. Members from other branches of service were also not eligible. RESULTS: Highly prevalent COVID-19 concerns included the inability to spend time with friends/family, social activities, and changing rules, regulations, and guidance related to COVID-19. Some information needs were endorsed by one quarter or more soldiers at both time points, including stress management/coping, travel, how to protect oneself, and maintaining mission readiness. COVID-19 concerns and information needs were most prevalent among non-White soldiers. Concerns and information needs did not decline overall between the assessments. Finally, COVID-19 concerns were associated with greater risk of multiple adverse mental health outcomes at both time points. CONCLUSIONS: COVID-19 concerns and information needs were prevalent and showed little evidence of decrement over the course of the first 6 months of the pandemic. COVID-19 concerns were consistently associated with adverse mental health outcomes. These data highlight two targets and potential demographic subgroups such that local leadership and Army medicine and public health enterprises can be better prepared to monitor and address to maintain force health and readiness in the face of possible future biomedical threats.

RESUMO

The Coronavirus Disease 2019 (COVID-19) pandemic has significantly impacted employment and finances, childcare, and behavioral health across the United States. The Behavioral Health Advisory Team assessed the pandemic's impact on the behavioral health of U.S. Army soldiers and their families. Over 20,000 soldiers at three large installation groups headquartered in the northwestern continental U.S., Republic of Korea, and Germany participated in the cross-sectional survey. Multivariable logistic regression models indicated that key demographics (gender, rank), severity of household financial impact, changes in work situation due to childcare issues, and family members' difficulty coping (both self and spouse/partner and/or child) were independently and consistently associated with greater odds of screening positive for probable clinical depression and generalized anxiety, respectively. These findings highlight how Army families were impacted similarly by the pandemic as their civilian counterparts. Army leadership may action these findings with targeted support for soldiers and their families to ensure they are utilizing supportive services available to them, and that military services continually evolve to meet soldier and family needs during times of crisis and beyond.

RESUMO

Increased adiposity is associated with dysregulation of the endothelin system, both of which increase the risk of cardiovascular disease (CVD). Preclinical data indicate that endothelin dysregulation also reduces resting energy expenditure (REE). The objective was to test the hypothesis that endothelin receptor antagonism will increase REE in people with obesity compared with healthy weight individuals. Using a double blind, placebo-controlled, crossover design, 32 participants [healthy weight (HW): n = 16, BMI: 21.3 ± 2.8 kg/m2, age: 26 ± 7 yr and overweight/obese (OB): n = 16, BMI: 33.5 ± 9.5 kg/m2, age: 31 ± 6 yr] were randomized to receive either 125 mg of bosentan (ETA/B antagonism) or placebo twice per day for 3 days. Breath-by-breath gas exchange data were collected and REE was assessed by indirect calorimetry. Venous blood samples were analyzed for concentrations of endothelin-1 (ET-1). Treatment with bosentan increased plasma ET-1 in both OB and HW groups. Within the OB group, the changes in absolute REE (PLA: -77.6 ± 127.6 vs. BOS: 72.2 ± 146.6 kcal/day; P = 0.046). The change in REE was not different following either treatment in the HW group. Overall, absolute plasma concentrations of ET-1 following treatment with bosentan were significantly associated with kcal/day of fat (r = 0.488, P = 0.005), percentage of fat utilization (r = 0.415, P = 0.020), and inversely associated with the percentage of carbohydrates (r = -0.419, P = 0.019), and respiratory exchange ratio (r = -0.407, P = 0.023). Taken together, these results suggest that modulation of the endothelin system may represent a novel therapeutic approach to increase both resting metabolism and caloric expenditure, and reduce CVD risk in people with increased adiposity.NEW & NOTEWORTHY Findings from our current translational investigation demonstrate that dual endothelin A/B receptor antagonism increases total REE in overweight/obese individuals. These results suggest that modulation of the endothelin system may represent a novel therapeutic target to increase both resting metabolism and caloric expenditure, enhance weight loss, and reduce CVD risk in seemingly healthy individuals with elevated adiposity.

RESUMO

Rigorous model-based analysis can help inform state-level energy and climate policy. In this study, we utilize an open-source energy system optimization model and publicly available data sets to examine future electricity generation, CO2 emissions, and CO2 abatement costs for the North Carolina electric power sector through 2050. Model scenarios include uncertainty in future fuel prices, a hypothetical CO2 cap, and an extended renewable portfolio standard. Across the modeled scenarios, solar photovoltaics represent the most cost-effective low-carbon technology, while trade-offs among carbon constrained scenarios largely involve natural gas and renewables. We also develop a new method to calculate break-even costs, which indicate the capital costs at which specific technologies become cost-effective within the model. Significant variation in break-even costs are observed across different technologies and scenarios. We illustrate how break-even costs can be used to inform the development of an extended renewable portfolio standard in North Carolina. Utilizing the break-even costs to calibrate a tax credit for onshore wind, we find that the resultant wind deployment displaces other renewables, and thus has a negligible effect on CO2 emissions. Such insights can provide crucial guidance to policymakers weighing different policy options. This study provides an analytical framework to conduct similar analyses in other states using an open source model and freely available data sets.

RESUMO

Tissues from deceased donors provide important data for genomic research and Organ Procurement Organizations (OPOs) play a significant role. To understand the decisions of families who donated for transplantation and made decisions about donation to the Genotype-Tissue Expression Project (GTEx), we examined donation decisions of family decision makers (FDMs). 413 families were interviewed by telephone. The OPO staff who made the transplant and research requests completed self-administered surveys; a total of 309 matching surveys from 99 OPO staff were obtained. 76.8% of families donated to the GTEx project. Logistic regression analysis found that FDM consent to GTEx donation was associated with endorsement of policies to promote biobanking (OR = 1.35), positive attitudes about medical research (OR = 1.1), lack of concern regarding a breach of confidentiality (OR = 1.54), comfort with tissue donation (OR = 1.24), and prior authorization to solid organ donation (OR = 3.17). OPO staff characteristics associated with GTEx donation included being female (OR = 3.57), White (OR = 4.97), comfort with hospital staff role in donation (OR = 1.61), and number of topics discussed with families (OR = 57.9). Donor type, FDM attitudes, OPO staff sociodemographics, OPO comfort with the GTEx authorization process, and intensity of discussing research-specific issues were significantly associated with GTEx donation decisions.

RESUMO

Although the Army has recently begun the practice of embedding behavioral health care providers (EBHP) in units in an effort to improve soldier well-being, the efficacy of this practice has not been evaluated. This study assesses 1 of the first programs implemented by the military. Using cross-sectional data obtained from a confidential survey of 12 company-level units in the California Army National Guard (n = 1,132), this study examines differences between units with and without EBHPs across a number of measures. Multilevel analysis of behavioral health symptoms, unit climate, perceptions of stigma, and practical barriers to care failed to detect main effects between units with EBHPs relative to those without. However, cross-level interactions were detected between unit EBHP status and soldiers reporting close relationship (e.g., spouse, girlfriend/boyfriend) impairment. Exploratory findings suggest that, among soldiers reporting close relationship impairment, those belonging to units with EBHPs reported significantly lower behavioral health symptoms and significantly more positive unit climates. Based on these limited exploratory finings, this study suggests that EBHPs in reserve units may have a positive effect on a subset of soldiers (i.e., those reporting close relationship impairment). More assessments of embed programs should be conducted, particularly using prospective longitudinal data among randomized units.

RESUMO

OBJECTIVE: To examine the relationships of race, sex, adiposity, adipokines, and physical activity to telomere length in adolescents. STUDY DESIGN: Leukocyte telomere length (T/S ratio) was assessed cross-sectionally in 667 adolescents (aged 14-18 years; 48% African-Americans; 51% girls) using a quantitative polymerase chain reaction method. Generalized estimating equations analyses were performed. RESULTS: Telomere length was greater in the African-American adolescents than in the Caucasian adolescents (age- and sex-adjusted T/S ratio ± SE, 1.32 ± 0.01 vs 1.27 ± 0.01: P = .014) and greater in girls than in boys (age- and race-adjusted T/S ratio ± SE, 1.31 ± 0.01 vs 1.27 ± 0.01; P = .007). None of the adiposity or adipokine measures explained a significant proportion of the variance in telomere length. Vigorous physical activity was positively associated with telomere length (adjusted R(2) = 0.019; P = .009) and accounted for 1.9% of the total variance only in girls. CONCLUSIONS: This study, conducted in a biracial adolescent cohort, demonstrated that (1) race and sex differences in telomere length have already emerged during adolescence; (2) adiposity and adipokines are not associated with telomere length at this age; and (3) the antiaging effect of vigorous physical activity may begin in youth, especially in girls.
