Poor glycemic control (HbA1c >7%) in diabetic patients undergoing PCI with drug-eluting stents significantly increases the risk of stent failure, particularly in-stent restenosis, highlighting considerations for strict glycemic management and a multidisciplinary approach to revascularization decisions.

Hypertensive urgency is the severe elevation in blood pressure (BP) without acute target organ damage. It differs from hypertensive emergency, in which end-organ damage, such as stroke, myocardial infarction (MI), or acute kidney injury, is present.

High-flow nasal cannula (HFNC) oxygen therapy is an advanced respiratory support modality that has gained widespread use in critical care, emergency medicine, and pulmonology.

The glomerular filtration rate (GFR) is a critical measurement of kidney function, reflecting how efficiently the kidneys filter blood. GFR varies by age, sex, and body size and is used to assess renal health, detect kidney disease, and guide treatment.

Coronary artery calcium (CAC) scoring helps in assessing patients with cardiovascular risk, particularly in those who are asymptomatic. The calcium score, derived from a computed tomography (CT) scan, quantifies calcified plaque in the coronary arteries, providing clinicians with insight into the patient’s risk for coronary artery disease (CAD) and cardiovascular events. Understanding how calcium scores vary by age is critical in optimizing risk stratification and guiding preventive therapies.

Spinal cord compression is a medical emergency requiring rapid diagnosis and intervention to prevent permanent neurologic deficits. Diagnosing this condition can be challenging, as low back pain is a common complaint, but only a small percentage of cases result from spinal cord compression.

A nursing team at Methodist Hospital in San Antonio, Texas, revised the Situation, Background, Assessment, and Recommendation handoff process between the emergency department and telemetry unit. It led to a few key improvements.

Emerging research suggests that metabolic health, particularly insulin resistance and mitochondrial dysfunction, plays a crucial role in the development and progression of Alzheimer’s disease.

Fractional flow reserve is the gold standard for guiding revascularization in patients with intermediate coronary stenoses, as it reduces unnecessary interventions and improves clinical outcomes. Quantitative flow ratio, an angiography-based computational method, offers a noninvasive alternative by analyzing coronary angiograms without pressure wires. Here's how they compared.

Whether citizen science projects require IRB oversight depends on their classification under the Common Rule for human subjects research. Although many citizen science projects are exempt, some conducted in collaboration with universities or nonprofits may still fall under IRB jurisdiction.
