Hidden Hypercortisolism in Refractory T2D (opens the original)
Read excerpt
In a 37-year-old patient with difficult-to-control type 2 diabetes (T2D), despite treatment with metformin, an SGLT2 inhibitor, and a GLP-1 agonist, A1c remains persistently elevated at 7.8%-8.5%. The patient also has central obesity and severe hypertension requiring three or more antihypertensive medications. Recent evidence suggests that this constellation of findings should raise suspicion for an often-overlooked underlying cause of poor glycemic control: occult hypercortisolism. This warning
Can Obesity Treatment With GLP-1 Drugs Last Forever? (opens the original)
Read excerpt

Ultraprocessed Foods and the Gut Microbiome (opens the original)
Read excerpt
Food additives commonly found in ultraprocessed foods may disrupt gut health through a variety of mechanisms, but the end result appears to be the same: dysbiosis and damage to the intestinal epithelial barrier, which normally helps protect the host from chronic inflammation. Some emulsifiers can erode the mucus layer, certain food colorings may be metabolized by commensal bacteria into pro-inflammatory compounds, artificial sweeteners may promote microbial imbalance, and nanoparticles may impai
How to Confirm Patients Understand Prescription Instructions (opens the original)
Read excerpt
Prescription instructions that seem straightforward to physicians may be misunderstood by patients, according to experts who recommend communication strategies to help physicians confirm patients’ understanding. For example, in Brazil, prescriptions often list the medication name followed by the notation “8/8 h” to indicate that a medication should be taken every 8 hours. Although the instruction is clear to physicians, some patients interpret it as taking one tablet at 8 AM and another at 8 PM.
