The Association Between Baseline Insulin Treatment and Cardiovascular Events: A Meta-Analysis.

OBJECTIVE: We conducted a meta-analysis to compare major adverse cardiovascular events (MACEs) in recent diabetes type 2 drugs cardiovascular outcome trials (CVOTs) in the subgroups that used insulin at baseline to the subgroups that did not. METHODS: English publications from 2010 to 2019 were searched in PubMed and Google Scholar. We searched published clinical trials for CVOTs with new drugs for type 2 diabetes and found 12 publications, of which 8 provided outcomes according to insulin use. We compared the event rate of the primary outcome in the group taking insulin with the one not taking insulin. Data were extracted by 2 investigators independently, including CVOT drug, publication year, sample size, duration of diabetes, mean glycated hemoglobin A1c, mean age, and number of patients in each treatment group. We included 8 trials in the analysis: DECLARE, EMPA-REG, EXSCEL, HARMONY, LEADER, SUSTAIN-6, EXAMINE, and SAVOR-TIMI. The pooled relative risk was 1.52 (95% CI, 1.43 ~ 1.62) when comparing the treatment group with insulin at baseline with the treatment group of patients without insulin use. RESULTS: In recent CVOTs, patients on insulin regimen along with the new antidiabetic drug had a higher risk ratio of cardiovascular events than patients who used the new antidiabetic drug alone.

BMI is Associated with Coronavirus Disease 2019 Intensive Care Unit Admission in African Americans.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has disproportionately impacted the African American community. This study aims to identify the risk factors for severe COVID-19 disease in African American patients. METHODS: This was a retrospective cross-sectional analysis of African American patients with COVID-19 treated between March 12 and April 9, 2020, at a single tertiary center. The primary outcome of interest was severe disease defined as those requiring intensive care unit (ICU) admission. RESULTS: The study included 158 consecutive patients. The mean age was 57 years, and 61% were women. The mean (SD) of BMI was 33.2 (8.6) kg/m2 . Overall, patients admitted to the ICU were older (62 vs. 55 years, P = 0.003) and had higher BMI (36.5 kg/m2 vs. 31.9 kg/m2 , P = 0.002). In unadjusted and adjusted analysis, the factors most associated with ICU admission in this sample were age (adjusted odds ratio [aOR]: 1.073; 95% CI: 1.033-1.114), BMI (aOR: 1.115; 95% CI: 1.052-1.182), and lung disease (aOR: 3.097; 95% CI: 1.137-8.437). CONCLUSIONS: This study identified risk factors for severe disease in COVID-19, specifically in an African American population. Further inclusive research aimed at optimizing clinical care relevant to the African American population is critical to ensure an equitable response to COVID-19.

Utility of DXA screening for diagnosis of osteoporosis in US veterans aged 70 years and older.

Dual energy X-ray absorptiometry (DXA) is recommended for osteoporosis screening in men aged 70 years and older but supportive data is limited. The aim of this study was to determine the efficacy of DXA for the diagnosis of increased fragility in this group of subjects. We retrospectively identified men aged 70 years and older without prior history of fracture and/or conditions predisposing to low bone mineral density (BMD) who attended the VA endocrinology clinic and performed DXA for osteoporosis screening. We analyzed the relationship between BMD and demographic, anthropometric data and biochemical parameters using linear regression models. Out of 55 subjects identified, 13 (24%) men had normal BMD, 30 (54%) had osteopenia and 12 (22%) had a diagnosis of osteoporosis based on the femoral neck (FN) T-score. Lumbar spine T-scores were normal in all three groups. Weight and body mass index (BMI) were significantly higher in the normal BMD group compared with the osteopenia and osteoporosis groups (p<0.001). After adjustments for age, weight, BMI, vitamin D concentrations, and diabetes status, differences in the FN BMD among the groups remained significant (p<0.001). Based on the Fracture Risk Assessment Tool (FRAX) score calculations in 43 non-osteoporotic patients, 15 patients with osteopenia had a 10-year hip fracture probability ≥3%. Screening with DXA in male US veterans aged 70 years and older without known osteoporosis risk factors revealed that up to 50% of men may qualify for diagnostic workup to determine the etiology of low BMD and/or to meet criteria to initiate pharmacological therapy to reduce future fracture risk.
