Maintenance of Self-Care Activities During COVID-19 Lockdown in Patients with Type 2 Diabetes That Received a Comprehensive Care Program Training.

Introduction: In 2020, several countries established a global emergency state. Lockdowns restricted people's lifestyles and daily activities to prevent coronavirus spread. These measures hindered diabetes mellitus control and lifestyle changes. This study aims to evaluate if attending a multidisciplinary program before the pandemic helped maintain a good metabolic state, lifestyle modifications, and mental health in patients with diabetes mellitus during the COVID-19 lockdown. Methods: Patients included in this study attended a multidisciplinary program, with <5 years of diagnosis of type 2 diabetes, without disabling complications, between 18-70 years old. The complete lockdown occurred from February 27, 2020, to May 31, 2020. The first patient (non-COVID) to return to the center for face-to-face consultation was in March 2021. Consultations in 2019 were face-to-face and changed to a virtual modality during 2020. We analyzed metabolic, lifestyle, mental health, and diabetes education parameters. Results: A total of 133 patients with type 2 diabetes mellitus were included with complete information in visits before and during the lockdown. Metabolic parameters and self-care measures (nutrition plan, foot evaluation, and self-glucose monitoring) evaluated on our patients had no change during the lockdown. We found a significant increase in the time patients spent sitting during the day (p<0.05). Barriers to exercise increased during lockdown, being joint pain (3.8% to 12.0%, p<0.01) and lack of time to exercise (4.5% to 7.5%, p=0.33) being the most common. There was no significant difference in symptoms of anxiety and depression, quality of life, and empowerment. Conclusion: A multidisciplinary diabetes mellitus program, including diabetes education for self-care activities, positively impacts patients, maintaining good outcomes despite lockdown difficulties.

Serum Vitamin D Levels Are Associated With Increased COVID-19 Severity and Mortality Independent of Whole-Body and Visceral Adiposity.

INTRODUCTION: Coronavirus disease (COVID-19) is a global pandemic. Vitamin D deficiency has been associated with susceptibility to infectious disease. In this study, the association between COVID-19 outcomes and vitamin D levels in patients attending a COVID-19 reference center in Mexico City are examined. METHODS: Consecutive patients with confirmed COVID-19 were evaluated. All patients underwent clinical evaluation and follow-up, laboratory measurements and a thoracic computerized tomography, including the measurement of epicardial fat thickness. Low vitamin D was defined as levels <20 ng/ml (<50nmol/L) and deficient Vitamin D as a level ≤12 ng/ml (<30 nmol/L). RESULTS: Of the 551 patients included, low vitamin D levels were present in 45.6% and deficient levels in 10.9%. Deficient Vitamin D levels were associated with mortality (HR 2.11, 95%CI 1.24-3.58, p = 0.006) but not with critical COVID-19, adjusted for age, sex, body-mass index and epicardial fat. Using model-based causal mediation analyses the increased risk of COVID-19 mortality conferred by low vitamin D levels was partly mediated by its effect on D-dimer and cardiac ultrasensitive troponins. Notably, increased risk of COVID-19 mortality conferred by low vitamin D levels was independent of BMI and epicardial fat. CONCLUSION: Vitamin D deficiency (≤12 ng/ml or <30 nmol/L), is independently associated with COVID-19 mortality after adjustment for visceral fat (epicardial fat thickness). Low vitamin D may contribute to a pro-inflammatory and pro-thrombotic state, increasing the risk for adverse COVID-19 outcomes.
