Impact of COVID-19 Vaccine Rollout on Mental Health, Social Determinants of Health, and Attitudes Among Individuals With COPD.

Background: Social distancing early in the COVID-19 pandemic helped mitigate viral spread and protect vulnerable populations. Broad availability of vaccines allowed social re-integration, but effects on mental health, social determinants of health, and attitudes among individuals with COPD, who are high-risk for adverse outcomes following COVID-19 infection, are unknown. Methods: Participants in the Losartan Effects on Emphysema Progression (LEEP) trial were recruited into an ancillary study from May-November 2020. Study coordinators administered telephone questionnaires to evaluate respiratory symptoms (COPD Assessment Test [CAT]), anxiety (Generalized Anxiety Disorder-7 [GAD-7]) and depressive (Patient Health Questionnaire [PHQ-8]) symptoms, social isolation, instrumental support, and attitudes and actions related to the COVID-19 pandemic. Generalized estimating equation models evaluated changes in patient-reported scores from the period before vaccine availability (pre-vaccine, May-December 2020) to the post-vaccine period (May 2021-September 2022). Results: Of 157 enrolled participants, 138 were interviewed during both periods. Compared with the pre-vaccine period, severe respiratory symptoms (CAT>20) were higher in the post-vaccine period (odds ratio [OR] 1.36, 95% confidence interval [95%CI]: 1.00-1.85), as were moderate anxiety symptoms (GAD-7≥10; OR 1.65, 95%CI: 1.11-2.46) and moderate depressive symptoms (PHQ-8≥10; OR 1.77, 95%CI: 1.22-2.55). Social isolation improved, though not significantly, and instrumental support was unchanged. In the post-vaccine period compliance with COVID-19 mitigation strategies remained high and governmental healthcare entities were viewed as trustworthy by fewer respondents. Conclusion: Despite a trend towards less social isolation following broad availability of COVID-19 vaccines, individuals with COPD reported worse symptoms, and greater anxiety and depressive symptoms compared to the pre-vaccine period.

Sepsis-induced cardiomyopathy is associated with higher mortality rates in patients with sepsis.

BACKGROUND: Patients with sepsis are at risk for developing sepsis-induced cardiomyopathy (SIC). Previous studies offer inconsistent results regarding the association of SIC and mortality. This study sought to assess whether SIC is linked to mortality in patients with sepsis and to evaluate predictors of the development of SIC. METHODS: In this retrospective study, patients admitted to the medical intensive care unit with a diagnosis of sepsis in the absence of acute coronary syndrome were included. SIC was identified using transthoracic echo and was defined by a new onset decline in left ventricular ejection fraction (LVEF) ≤50%, or ≥10% decline in LVEF compared to baseline in patients with a history of heart failure with reduced ejection fraction. Multivariable logistic regression analysis was performed using the R software program. RESULTS: Of the 359 patients in the final analysis, 19 (5.3%) had SIC. Eight (42.1%) of the 19 patients in the SIC group and 60 (17.6%) of the 340 patients in the non-SIC group died during hospitalization. SIC was associated with an increased risk for all-cause in-hospital mortality (odds ratio [OR], 4.46; 95% confidence interval [CI], 1.15-18.69; P=0.03). Independent predictors for the development of SIC were albumin level (OR, 0.47; 95% CI, 0.23-0.93; P=0.03) and culture positivity (OR, 8.47; 95% CI, 2.24-55.61; P=0.006). Concomitant right ventricular hypokinesis was noted in 13 (68.4%) of the 19 SIC patients. CONCLUSIONS: SIC was associated with an increased risk for all-cause in-hospital mortality. Low albumin level and culture positivity were independent predictors of SIC.

Adiponectin and the steatosis marker Chi3L1 decrease following switch to raltegravir compared to continued PI/NNRTI-based antiretroviral therapy.

BACKGROUND: People with HIV are at for metabolic syndrome (MetS) and fatty liver disease, but the role of Antiretroviral therapy (ART) is poorly understood. MetS and fatty liver disease been associated with changes in adiponectin, soluble ST2 (sST2), chitinase 3-like 1 (Chi3L1), hyaluronic acid (HA), tissue inhibitor of metalloproteinase-1 (TIMP-1), lysyl oxidase-like-2 (LOXL2) and transforming growth factor ß (TGF-ß) concentrations in HIV-uninfected populations. Protease (PI) and non-nucleoside reverse transcriptase inhibitors (NNRTI) may contribute to these comorbidities, but the effects of switching from PI- or NNRTI to raltegravir (RAL) on these biomarkers is unknown. METHODS: Cryopreserved plasma was obtained from a completed, prospective trial of HIV-infected women with central adiposity on NNRTI- or PI-based ART during which they were randomized to remain on their current ART or switch to a RAL based regimen. Biomarker concentrations were quantified using ELISA and Multiplex assays at baseline and 24 weeks after randomization. Wilcoxon-signed rank test evaluated within-group changes, Spearman and linear regression models evaluated correlations between biomarkers and clinical covariates. RESULTS: Participants had a median age of 43 years, CD4+ T lymphocyte count 558 cells/mm3 and BMI 32 kg/m2; 35% met criteria for MetS. At baseline, higher adiponectin levels correlated with higher Chi3L1 levels (r = 0.42, p = 0.02), as did declines after 24 weeks (r = 0.40, p = 0.03). Changes in sST2 correlated with changes in Chi3L1 (r = 0.43, p = 0.02) and adiponectin (r = 0.40, p = 0.03). Adiponectin and Chi3L1 levels decreased significantly in women switched to RAL vs continue PI/NNRTI. CONCLUSION: In women with HIV and central obesity, the hepatic steatosis/fibrosis marker Chi3L1 and adiponectin decrease in conjunction with sST2 decreases following switch to RAL. Whether switching from NNRTI/PI-based regimens to RAL can improve hepatic steatosis and dysmetabolism requires further study. TRIAL REGISTRATION: Clinicaltrials.gov NCT00656175.
