Telephone Virtual Versus In-Person Pharmacotherapy-Based Obesity Care: A COVID-19-Related Experience at a Veterans Administration Facility.

Background: Most of the Veterans Administration (VA) population is either overweight or obese, which is a serious health concern. Medical weight management visits have traditionally occurred through in-person clinics. However, the COVID-19 pandemic forced care delivery to virtual platforms. Methods: We compared weight loss with in-person versus telephone-based medical weight management (lifestyle counseling coupled with pharmacotherapy) delivered by physician and nurse practitioner visits during the pandemic. We designed a program evaluation utilizing a naturalistic (pragmatic) observational study structure, including both newly enrolled and previously established participants in the Minneapolis VA MOVE! program between 2017 and 2021. A "transition" cohort (n = 74) received in-person care from March 2019 to March 2020, and then transitioned to virtual care. A "new start" virtual care cohort (n = 149) enrolled after March 2020 was compared to a separate historical group (n = 180) that received in-person care between January 2017 and December 2019. Weight loss was accessed over a 9-month period in both cohorts. Results: Mean weight loss over 9 months was -6.5 ± 18.2 and -2.5 ± 13.3 lbs in the in-person and virtual phases of the transition cohort, respectively, without significant difference between the two phases (p = 0.22). Mean weight loss over 9 months in the new start (virtual) cohort was -14.4 ± 17.0 lbs compared to -16.7 ± 21.0 lbs in the historical cohort, without significant difference between groups (p = 0.44). Conclusions: In our naturalistic study in a single-site VA clinic setting, weight loss with telephone-based medical weight management during the pandemic was comparable to in-person care. These findings are important for veterans living in rural and/or underserved areas.

Clinical Presentation and Diagnostic Approach to Hypoglycemia in Adults Without Diabetes Mellitus.

OBJECTIVE: To review the clinical presentation, causes, and diagnostic approach to spontaneous hypoglycemia in adults without diabetes mellitus. METHODS: A literature review was performed using the PubMed and Google Scholar databases. RESULTS: Hypoglycemia is uncommon in people who are not on glucose-lowering medications. Under normal physiologic conditions, multiple neural and hormonal counterregulatory mechanisms prevent the development of abnormally low levels of plasma glucose. If spontaneous hypoglycemia is suspected, the Whipple triad should be used to confirm hypoglycemia before pursuing further diagnostic workup. The Whipple criteria include the following: (1) low levels of plasma glucose, (2) signs or symptoms that would be expected with low levels of plasma glucose, and (3) improvement in those signs or symptoms when the level of plasma glucose increases. Spontaneous hypoglycemia can be caused by conditions that cause endogenous hyperinsulinism, including insulinoma, postbariatric hypoglycemia, and noninsulinoma pancreatogenous hypoglycemia. Spontaneous hypoglycemia can also be seen with critical illness, hepatic or renal dysfunction, hormonal deficiency, non-diabetes-related medications, and non-islet cell tumors. The initial diagnostic approach should begin by obtaining a detailed history of the nature and timing of the patient's symptoms, medications, underlying comorbid conditions, and any acute illness. A laboratory evaluation should be conducted at the time of the spontaneous symptomatic episode. Supervised tests such as a 72-hour fast or mixed-meal test may be needed to recreate the situation under which the patient is likely to experience symptoms. CONCLUSION: We provide an overview of the physiology of counterregulatory response to hypoglycemia, its causes, and diagnostic approaches to spontaneous hypoglycemia in adults.
