Introduction We previously reported predictors of mortality in 1786 adults with diabetes or stress hyperglycemia (glucose>180 mg/dL twice in 24 hours) admitted with COVID-19 from March 2020 to February 2021 to five university hospitals. Here, we examine predictors of readmission.Research design and methods Data were collected locally through retrospective reviews of electronic medical records from 1786 adults with diabetes or stress hyperglycemia who had a hemoglobin A1c (HbA1c) test on initial admission with COVID-19 infection or within 3 months prior to initial admission. Data were entered into a Research Electronic Data Capture (REDCap) web-based repository, and de-identified. Descriptive data are shown as mean±SD, per cent (%) or median (IQR). Student’s t-test was used for comparing continuous variables with normal distribution and Mann-Whitney U test was used for data not normally distributed. X2 test was used for categorical variable.Results Of 1502 patients who were alive after initial hospitalization, 19.4% were readmitted; 90.3% within 30 days (median (IQR) 4 (0–14) days). Older age, lower estimated glomerular filtration rate (eGFR), comorbidities, intensive care unit (ICU) admission, mechanical ventilation, diabetic ketoacidosis (DKA), and longer length of stay (LOS) during the initial hospitalization were associated with readmission. Higher HbA1c, glycemic gap, or body mass index (BMI) were not associated with readmission. Mortality during readmission was 8.0% (n=23). Those who died were older than those who survived (74.9±9.5 vs 65.2±14.4 years, p=0.002) and more likely had DKA during the first hospitalization (p

ABSTRACT Silicone/mineral oil‐induced granulomas have been described as an inflammatory granulomatous response when silicone/mineral oil is injected for cosmetic purposes. These sclerosing granulomas can lead to hypercalcemia. Here we present a 33‐year‐old man with hypercalcemia, hypophosphatemia, progressively worsening fatigue, severe proximal muscle weakness, and depression. He had an athletic build with increased muscle bulk and several areas of indurated, nontender, firm, well‐circumscribed lesions in the subcutaneous tissue of his anterior pectoralis, triceps, and biceps bilaterally because of injecting himself with silicone/mineral oil‐based product into his muscles. Sclerosing granulomas were diagnosed on the MRI. He had extremely low or undetectable serum levels of 25‐hydroxyvitamin D [25(OH)D], and persistently elevated serum levels of 1,25‐dihydroxyvitamin D [1,25(OH)2D] and calcium. He developed hypophosphatemia associated with elevated levels of fibroblast growth factor 23 (FGF‐23) and severe proximal muscle weakness. Treatment with systemic steroids, furosemide, calcitonin, ketoconazole, and denosumab resulted in a significant decrease in his serum calcium, but with minimal impact on his hypophosphatemia and fatigue.Correcting his severe vitamin D deficiency with small doses of vitamin D and raising his blood level of 25(OH)D from undetectable to 10 ng/mL without significantly affecting his serum calcium or phosphate was effective in reversing his severe proximal muscle weakness, permitting him to lift his head and to be free of his wheelchair. Although measurement of the 1,25(OH)2D level is not mandatory in all cases of hypercalcemia, it is indicated in a patient who has low serum PTH levels. Clinicians need to be aware that vitamin D deficiency can cause severe proximal muscle weakness such that the patient is unable to lift his head from his chest or ambulate. This may lead to a psychiatric disorder misdiagnosis. © 2019 The Authors. JBMR Plus is published by Wiley Periodicals, Inc. on behalf of the American Society for Bone and Mineral Research.

Objective: Diabetes mellitus is associated with poor outcomes in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Diabetic ketoacidosis (DKA) has also been reported to occur with this virus. A cluster of cases of euglycemic DKA (euDKA) was identified in patients with type 2 diabetes mellitus using sodium-glucose cotransporter-2 inhibitors (SGLT2is) who developed SARS-CoV-2 infection. Methods: The cases were identified by the authors while providing clinical care, and details were collected. Results: Five cases of euDKA, presenting with glucose levels
