Abstract Background Adipose tissue influences blood pressure regulation through depot-specific endocrine, inflammatory, and exosome-dependent mechanisms. While obesity is a well-established risk factor for hypertension, emerging evidence suggests that distinct fat depots may contribute to vascular dysfunction independent of total adiposity. Methods: This review synthesizes post-2020 literature on 6 anatomically defined depots: visceral, perivascular, epicardial, bone marrow, brown, and beige adipose tissue, with an emphasis on their mechanistic roles, imaging biomarkers, and translational relevance. Results Alterations in adipose depot function can impair nitric oxide signaling, promote oxidative stress, and modulate sympathetic tone, even in the absence of obesity. Exosomal microRNAs from dysfunctional adipose tissue further disrupt vascular homeostasis. Although clinical tools for assessing depot dysfunction are limited, advances in imaging and molecular profiling may enable targeted therapeutic strategies. Conclusions Reframing adipose tissue as a modular regulator of blood pressure, rather than a passive consequence of obesity, may unlock new venues for precision management of hypertension.

ABSTRACT Common variable immunodeficiency (CVID) is a primary immunodeficiency disorder causing hypogammaglobulinemia. Although rare, nodular regenerative hyperplasia is the most common liver complication in CVID, which can progress to noncirrhotic portal hypertension. We report a case of a young male with CVID presenting with recurrent parastomal bleeding secondary to noncirrhotic portal hypertension from CVID-associated nodular regenerative hyperplasia.

AbstractBackgroundIdentifying patient‐, facility‐, and environment‐level factors that influence the initiation and retention of comprehensive lifestyle management interventions (CLMI) for urban and rural Veterans could improve obesity treatment and reach at Veterans Affairs (VA) facilities.AimsThis study identified factors at these various levels that predicted treatment engagement, retention, and weight management among urban and rural Veterans.MethodsA retrospective cohort study of 631,325 Veterans was designed using VA databases to identify Veterans with class II and III obesity during 2015–2017. Primary outcomes were initiation of CLMI, bariatric surgery, or obesity pharmacotherapy within 1 year of index date. Secondary outcomes included treatment retention and successful weight loss. Generalized linear mixed models were used to evaluate the relationships between factors and obesity‐related outcomes, with rurality differences assessed through interaction terms.ResultsPatient characteristics associated with increased odds of initiating CLMI included female sex (p < 0.001), black race (p < 0.001), sleep apnea (p < 0.001), mood disorder (p < 0.001), and use of medications associated with weight loss (p < 0.001) or weight gain (p < 0.001). Facility use of telehealth was associated with greater odds of CLMI initiation in urban Veterans (p < 0.001) but lower retention in both populations (p = 0.003). Routine consideration of pharmacotherapy was associated with higher CLMI initiation. Environmental characteristics associated with increased odds of CLMI initiation included percent of population foreign born (OR = 1.03 per 10% increase; p < 0.001), percent black (p < 0.001), and high walkability index (p < 0.001). The relationship between total population and CLMI initiation differed by rurality, as greater population was associated with lower odds of CLMI initiation in urban areas (OR: 0.99 per 1000 population; p < 0.001), but higher odds in rural areas (OR:1.01, p = 0.01). Veterans in the south were less likely to initiate CLMI and had lower retention (p < 0.001).ConclusionTreatment and retention of CLMI among Veterans remain low, highlighting areas for improvement to expand its reach both urban and rural Veterans.

As anti-diversity, equity, and inclusion (DEI) legislation continues to gain traction, it is essential for those in science, technology, engineering, mathematics, and medicine (STEMM) to grasp its implications and explore ways to preserve inclusive environments. Anti-DEI measures can result in the dismantling of support structures, such as DEI centers and peer counseling groups, leading to a decline in vital support programs on college campuses and beyond. In this Voices article, we examine these emerging challenges and underscore the critical need to reframe DEI as a tool for fostering inclusion and benefits all individuals.

AbstractThere is conflicting evidence in select mouse models and humans that suggest angiotensin‐converting enzyme 2 expression is increased due to treatment with angiotensin converting enzyme inhibitors and angiotensin receptor blockers (ACEI/ARBs). Given the wide range of conditions that these medications treat, further evaluation is necessary to determine safety in the context of COVID‐19. We sought to determine the association between use of ACEI/ARBs and COVID‐19 severity in patients with essential hypertension. We included 714 patients with essential hypertension diagnosed with COVID‐19 and admitted to University of Iowa Healthcare from March 1, 2020 to June 29, 2021. Severity of COVID‐19 infection was assessed based on mortality, length of stay in hospital, intensive care unit admission, and use of supplemental oxygen, invasive ventilation, and vasopressors. Multivariable logistic and linear regression analyses were used for binary and continuous outcomes, respectively. Prior exposure to ACEI/ARBs before admission was significantly associated with lower mortality (OR: 0.454, p = .015), shorter length of stay in hospital (p < .001), and decreased adjusted odds of intensive care admission (OR: 0.719; p < .042). The present results suggest that patients with essential hypertension hospitalized with COVID‐19 who had a prescription for ACEI/ARBs prior to admission exhibited less severe COVID‐19 and lower in‐hospital mortality.

AbstractIn academia, particularly in science, technology, engineering, and mathematics (STEM), writing accountability groups have emerged as an effective technique to enhance writing productivity by offering structure, increasing the commitment to write, and fostering social commitment. The rapid development of technology has introduced a new challenge across STEM fields: technostress, where individuals face heightened stress due to novel applications of technology. To address this, we introduce Technology Accountability Groups (TAGs), a novel form of community support for graduate students and faculty. TAGs are tailored to help individuals navigate technological innovations, alleviate technostress, acquire new skills, motivate, and connect with leaders in the field. This paper presents a framework for establishing, implementing, and sustaining TAGs in STEM.
