In this special edition of DOC Updates, Neil Skolnik speaks with Dr. Juan Frias, who catalogues the latest cardiometabolic medications, emphasizing the distinguishing characteristics of each. This special episode is sponsored with support from Lilly. Presented by: Neil Skolnik, MD, Professor of Family and Community Medicine, Sidney Kimmel Medical College, Thomas Jefferson University; Associate Director, […]

Share on PinterestSome GLP-1 users report changes in their taste and smell, according to a new study. Tatsiana Volkava/Getty Images Researchers report that GLP-1 drugs used to treat type 2 diabetes may impair a person’s sense of taste and smell. Experts say taste and smell dysfunction doesn’t appear to be a common side effect of […]

Share on PinterestResearchers compared intermittent fasting with calorie counting and found that people following fasting protocols thought about food less often. Anchiy/Getty Images A recent study found that people who bounce from one diet to another — or “yo-yo dieters” — may have better results following an intermittent fasting diet plan. The study compared intermittent […]

Share on PinterestAn estimated 14 million Medicare Part D recipients could obtain Wegovy, Foundayo, and Zepbound for $50 per month. Johner Images/Getty Images Federal officials announced the launch of a Medicare GLP-1 Bridge pilot program that reduces the cost of certain GLP-1 medications prescribed for weight loss. Under the program, Wegovy, Foundayo, and Zepbound KwikPens […]
Read MoreGRP78/BiP/HSPA5 is a widely expressed endoplasmic reticulum (ER) chaperone that also performs the critical role of regulating the unfolded protein response, an adaptive mechanism that maintains ER homeostasis. As the exclusive source of circulating insulin, pancreatic β-cells are prone to ER stress due to proinsulin synthesis workload. GRP78 is important for the ER stress response, […]
Read MoreProgressive loss of pancreatic β-cell mass (BCM) is a hallmark of type 2 diabetes, yet strategies to preserve or restore BCM remain elusive due to incomplete understanding of the molecular mechanisms governing β-cell proliferation in adults. The unfolded protein response (UPR) maintains endoplasmic reticulum (ER) proteostasis, but the in vivo role of activating transcription factor 6α […]
Read MoreGlucokinase and ATP-sensitive potassium (KATP) channels in pancreatic β-cells control insulin secretion in response to glucose stimulation to maintain glucose homeostasis. It is well established that loss-of-function (LOF) variants in GCK, which encodes glucokinase, are diabetogenic, whereas LOF variants in KATP channel genes lead to congenital hyperinsulinism (HI) and hypoglycemia. However, how the co-occurrence of […]
Read MoreThis study characterized the dose effect of whey protein isolate (WPI) ingestion on glucagon secretion, glycemia, and the underlying mechanisms in adults with type 1 diabetes. Twelve insulin pump–treated adults with type 1 diabetes (mean ± SD age 47.3 ± 16.4 years; BMI 26.1 ± 3.8 kg/m2) and six adults without diabetes (age 36.2 ± […]
Read MoreAttrition of islet function is observed over time following total pancreatectomy with islet autotransplantation (TPIAT). Metabolic stress on a suboptimal islet mass is a suspected, but unconfirmed, contributor. We measured proinsulin–to–C-peptide (PI:C) ratios as an indicator of β-cell stress in TPIAT recipients >5 years post-TPIAT. Individuals ≥16 years old with TPIAT 5–20 years prior underwent […]
Read MoreMicroRNAs (miRNAs) are small RNAs that posttranscriptionally repress gene expression of their target mRNAs. miRNA discovery dates to 1993, when Ambros and Ruvkun identified them in nematodes. More than two decades later, their pioneering research was recognized with the Nobel Prize in Medicine, a fitting acknowledgment of the profound impact these tiny molecules exert on […]
