‘Browning’ the cardiac and peri-vascular adipose tissues to modulate cardiovascular risk

Excess visceral adiposity, in particular that located adjacent to the heart and coronary arteries is associated with increased cardiovascular risk. In the pathophysiological state, dysfunctional adipose tissue secretes an array of factors modulating vascular function and driving atherogenesis. Conversely, brown and beige adipose tissues utilise glucose and lipids to generate heat and are associated with improved cardiometabolic health. The cardiac and thoracic perivascular adipose tissues are now understood to be composed of brown adipose tissue in the healthy state and undergo a brown-to-white transition i.e. during obesity which may be a driving factor of cardiovascular disease. In this review we discuss the risks of excess cardiac and vascular adiposity and potential mechanisms by which restoring the brown phenotype i.e. “re-browning” could potentially be achieved in clinically relevant populations

Detrimental Effects of Psychotropic Medications Differ by Sex in Aging People with HIV

Unauthorized reproduction of this article is prohibited. Background:Mental health conditions are common among persons with HIV (PWH). An understanding of factors associated with prescription medication use for these conditions and clinical impact of the prescription medications may improve care of mental health disorders in PWH.Methods:Psychotropic medication use was examined among PWH within the AIDS Clinical Trials Group A5322 (HAILO) study. Multivariable logistic models and Cox regression models estimated the association between psychotropic medications (any/none) with baseline and incident slow gait (\u3e1 s/m) and neurocognitive impairment (NCI) for more than 4 years.Results:Of 1035 participants, the median age was 51 years.81% were men, 30% black, non-Hispanic, and 20% Hispanic. Psychotropic medication use was similar between men (34%) and women (38%; P = 0.19). PWH using psychotropic medications had greater odds of baseline slow gait {odds ratio 1.61, [95% confidence interval (CI): 1.23 to 2.10]; P \u3c 0.001}. Men but not women using psychotropic medications had an increased risk of developing slow gait [hazard ratio 1.85; (1.29 to 2.65) vs 0.77; (CI: 0.35 to 1.68), P interaction = 0.045]. The sex-specific odds ratios for medication use and NCI were qualitatively but not statistically different [men: 1.79; (1.14-2.80); women: 1.27; (0.56-2.90); P interaction = 0.47]. Psychotropic medication use was associated with an increased risk of incident NCI [hazard ratio 2.18; (95% CI: 1.23 to 3.84), P = 0.007] in both men and women.Conclusions:Psychotropic medications are associated with impairment in functional outcomes of aging, with a greater risk of baseline NCI and incident slow gait among men. Further investigation is needed to optimize outcomes in PWH and prescription of psychotropic medications among both men and women

Racial and Ethnic Differences in Sociodemographic, Clinical, and Treatment Characteristics Among Patients with Atopic Dermatitis in the United States and Canada: Real-World Data from the CorEvitas Atopic Dermatitis Registry

INTRODUCTION: This real-world, cross-sectional study compared sociodemographic, clinical and treatment characteristics, and patient-reported outcomes (PROs) among racial/ethnic groups in patients with atopic dermatitis (AD) who are candidates for systemic therapy. METHODS: This study included adults with dermatologist- or dermatology practitioner-diagnosed AD enrolled in the CorEvitas AD Registry (July 2020-July 2021). All patients initiated systemic therapy within 12 months prior to or at enrollment or had moderate-to-severe AD (vIGA-AD ≥ 3 and Eczema Area and Severity Index [EASI] ≥ 12) at enrollment. Patients were categorized into five mutually exclusive racial/ethnic groups: non-Hispanic White, Black, Asian, Other/Multiracial, and Hispanic (any race). Patient, clinical, and treatment characteristics were captured at enrollment. Differences in means or proportions of characteristics among racial/ethnic groups were descriptively summarized using effect sizes. Adjusted prevalence ratios and mean differences were estimated (White race/ethnicity group as the reference category) with 95% confidence intervals (CI). RESULTS: Among 1288 patients, 64% (n = 822) were White, 13% (n = 167) Black, 10% (n = 129) Asian, 8% (n = 97) Hispanic, and 6% (n = 73) Other/Multiracial. In adjusted analyses, statistically more severe EASI lichenification was noted among Black compared with White patients at the head and neck (mean difference, 0.21, [95% CI 0.06, 0.36]; p = 0.01), trunk (0.32, [0.17, 0.47]; p \u3c 0.001), upper extremities (0.27, [0.09, 0.44]; p = 0.008), and lower extremities (0.39, [0.21, 0.57]; p \u3c 0.001). Statistically more severe EASI lichenification was observed among Asian vs White patients in certain areas (mean difference, head and neck, 0.22 [0.04, 0.39], p = 0.01; trunk, 0.25 [0.07, 0.43], p \u3c 0.001; lower extremities, 0.22 [0.01, 0.43], p \u3c 0.001) and SCORing for AD lichenification (mean difference: 0.34 [0.15, 0.52]; p \u3c 0.001). Significantly higher mean pruritus over the past 7 days for Black (mean difference: 0.63 [0.01, 1.26] and Hispanic patients (0.60 [0.11, 1.09]; p = 0.03) vs White patients was observed. Among AD clinical features, the prevalence of facial erythema was significantly lower among Black compared with White patients (prevalence ratio = 0.38, [0.22, 0.67]; p = 0.007). CONCLUSION: Racial/ethnic differences exist in sociodemographic, clinical and treatment characteristics, disease severity, and PROs among real-world AD patients who are candidates for systemic therapy. Recognizing these variations may be of critical importance for dermatologists for the design and delivery of targeted/personalized medicine approaches
