Reversible cerebral vasoconstriction syndrome is a common, increasingly recognized cause of thunderclap headache. Most patients have some type of trigger that precedes the onset (e.g., orgasm, physical exertion, Valsalva maneuvers, exposure to vasoconstrictive medications) followed by multiple short-duration thunderclap headaches that occur over days to weeks. Physical examination is often without focal neurological deficits. ⋯ Treatment is primarily analgesics and avoidance of triggers. Triptans, steroids and immunosuppressive agents, which are sometimes used if migraine or central nervous system angiitis is suspected, should be avoided. Improved recognition of RCVS will likely lead to earlier diagnosis and minimize potentially harmful empiric treatment strategies.

Diabetes has classically been associated with atherosclerotic cardiovascular disease. However, heart failure is now increasingly recognized as a prevalent and often first cardiovascular complication among patients with diabetes. ⋯ The lack of specific therapy has been recognized as an unmet clinical need. In this review, we summarize current understanding of the hallmark metabolic and structural changes of diabetic cardiomyopathy, appraise current tools for diagnosis and staging among patients, and describe the emerging but still preclinical data on therapeutic options.

Climate change is leading to a rise in heat-related illnesses, vector-borne diseases, and numerous negative impacts on patients' physical and mental health outcomes. Concurrently, healthcare contributes about 4.6% of global greenhouse gas emissions. Low-value care, such as overtesting and overdiagnosis, contributes to unnecessary emissions. ⋯ Second, diagnostic quality issues, such as overtesting and overdiagnosis, contribute to climate change through unnecessary emissions and waste and should be targeted for interventions. We also highlight implications for clinical practice, research, and policy. Our findings call for efforts to engage healthcare professionals and policymakers in understanding the urgent implications for diagnosis in the context of climate change and reducing global greenhouse gas emissions to enhance both patient and planetary outcomes.

In the Western world, sales of alcoholic beverages are skyrocketing. Alcohol (ethanol) is consumed for its transient euphoric effects but is a risk factor for the development of heart disease. Here, we review the possible association between alcohol consumption and atrial fibrillation. ⋯ These include studies of individuals drinking only moderate amounts of alcoholic beverages (aka the "French paradox") on the one hand, and paroxysmal atrial fibrillation after binge drinking ("holiday heart syndrome") on the other hand. The evidence available in the literature suggests that hypertension, structured heart disease of any form, neurohumoral stress, and cardiometabolic disorders all favor the development of atrial fibrillation triggered by alcohol. We also suggest that alcohol should be classified as a modifiable risk factor for atrial fibrillation, and also for heart disease in general.

Sodium-glucose cotransporter 2 inhibitors (SGLT2i) have been shown to reduce the risk of hospitalizations from heart failure and cardiovascular mortality. However, SGLT2i therapy's potential effects on the risks of dementia and Parkinson's disease are not well established, with conflicting results based on observational studies. Hence, we sought to evaluate the association between SGLT2i and the risk of dementia and Parkinson's disease in patients with type 2 diabetes mellitus, heart failure, or chronic kidney disease. ⋯ Our study suggests that there is no significant association between SGLT2i use and the risk of dementia, its subtypes, and Parkinson's disease when compared with the control groups.
