Differences in Glycemic Control for Inpatients with Type 1 Diabetes on Insulin Pump Versus Subcutaneous Insulin Therapy.

BACKGROUND: Inpatient use of insulin pump therapy has been increasing due to greater availability of this technology, however there is a paucity of research that investigates glycemic control of inpatient insulin pump users. OBJECTIVE: To compare the glycemic control of hospitalized patients with type 1 diabetes (T1D) who used insulin pump vs. multiple daily injections (MDI). DESIGN: Retrospective chart review. PARTICIPANTS: Patients with T1D who were hospitalized between January 1, 2017, and December 31, 2019, in an academic medical center in the New York metropolitan area. MAIN MEASURES: Patients were categorized into three groups based on their method of insulin administration: "pump only" group used insulin pump exclusively, "MDI only" group used MDI only, and "intermittent pump" group used a combination of both methods. The primary endpoints are mean blood glucose, rates of hypoglycemic events (blood glucose < 70 mg/dL), and rates of hyperglycemic events (blood glucose > 250 mg/dL). Separate multivariable Poisson regressions were performed to determine the association between the type of insulin administration and rate outcomes (i.e., rate of hypoglycemic events and rate of hyperglycemic events). RESULTS: The study included 78 patients with a mean age of 51, who were mostly male (54%), and white (72%). The average proportion of glucose measurements that were hyperglycemic for the "pump only", "MDI only", and "intermittent pump" groups were 0.11 (SD = 0.11), 0.25 (SD = 0.19), and 0.24 (SD = 0.25), respectively. The "pump only" group has a significantly lower proportion of hyperglycemic events as compared to the "MDI only" group (p = 0.0227). CONCLUSIONS: In this sample, patients who exclusively used their insulin pump while inpatient had a lower rate of hyperglycemic events than patients who used MDI only; suggesting that select patients can safely continue their insulin pump therapy in the inpatient setting.

Demographic Variables Associated With Diabetes Technology Awareness or Use in Adults With Type 2 Diabetes.

Background: Studies in populations with type 1 diabetes highlight racial/ethnic disparities in the use of diabetes technology; however, little is known about disparities among those with type 2 diabetes. This project investigates the racial/ethnic and socioeconomic disparities in diabetes technology awareness and use in adults with type 2 diabetes in the ambulatory setting. Methods: Adults ≥40 years of age with type 2 diabetes in ambulatory care were invited to participate via an e-mail link to a de-identified REDCap (Research Electronic Data Capture) questionnaire. Variables, including awareness and use of continuous glucose monitoring (CGM) and insulin pumps, were summarized descriptively using frequencies and percentages and were compared across racial/ethnic groups, education level, and income using Pearson χ2 or Fisher exact tests. Results: The study included 116 participants, most of whom (62%) were White, elderly Medicare recipients. Compared with White participants, those of racially/ethnically minoritized groups were less likely to be aware of CGM (P = 0.013) or insulin pumps (P = 0.001). Participants with a high school education or less were also less likely to be aware of insulin pumps (P = 0.041). Interestingly, neither awareness nor use of CGM or insulin pumps was found to be associated with income. Conclusion: This cross-sectional analysis suggests that racially/ethnically minoritized groups and individuals with lower education have less awareness of CGM or insulin pumps.

De novo ulcerative colitis and Takotsubo cardiomyopathy following sleeve gastrectomy.

The increasing prevalence of severe obesity is a major public health concern. Bariatric surgery is an important treatment option for severe obesity due to its long-term sustained result. Multiple studies have shown that patients have an increased risk of developing inflammatory bowel disease following bariatric surgery. Takotsubo syndrome usually presents as acute left ventricular systolic dysfunction without corresponding obstructive coronary artery disease after an acute stress episode. We describe a unique case of a patient who developed de novo ulcerative colitis and takotsubo cardiomyopathy shortly after sleeve gastrectomy. The patient made a successful recovery due to prompt recognition and appropriate treatment.

Narrow Complex Tachycardia With Intermittent 2:1 Atrioventricular Relationship.

Narrow QRS complex tachycardia has a broad differential diagnosis. We present a series of rhythm strips with representative onset, transition from 2:1 AV conduction to 1:1 AV conduction, and offset of tachycardia. By analyzing these rhythm strips, we can identify the electrophysiologic mechanism and diagnosis. (Level of Difficulty: Intermediate.).

Hypertriglyceridemia-Induced Acute Pancreatitis, Euglycemic Diabetic Ketoacidosis and COVID-19 Infection in a Patient With Type 2 Diabetes Taking a Sodium-Glucose Cotransporter 2 Inhibitor.

Recent landmark trials have increased the use of sodium-glucose cotransporter 2 inhibitors (SGLT-2i) in patients with type 2 diabetes (T2D). A rare but serious side effect of SGLT-2i is euglycemic diabetic ketoacidosis (euDKA), which usually occurs in the setting of acute illness such as the coronavirus disease 2019 (COVID-19). We report a distinctive case of a patient with hyperlipidemia and T2D on SGLT-2i therapy who presented with hypertriglyceridemia-induced pancreatitis (HTGP) concurrently with euDKA and COVID-19. The patient's initial labs included venous blood gas pH of 7.27, a blood glucose level of 146 mg/dL, serum triglyceride (TG) greater than 8,300 mg/dL and lipase of 527 U/L. Viral polymerase chain reaction (PCR) result for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was also positive. We suspect this patient has a primary disorder of lipoprotein metabolism which was exacerbated by stress from euDKA and COVID-19 infection. The patient was treated with intravenous fluids, fasting and intravenous insulin infusion. Resolution of euDKA and improvement of hypertriglyceridemia to less than 1,000 mg/dL occurred by day 6 and the patient was transitioned to subcutaneous basal-bolus insulin. On discharge, the SGLT-2i was discontinued and the patient was discharged on insulin, metformin, omega-3 fatty acids, and fenofibrate.
