It reflects recent advancements in diagnostic methodologies and therapeutic strategies. It emphasizes the need for heightened awareness among healthcare providers about the complex relationship between SDB and various forms of heart failure.

Ventricular assist devices and sleep-disordered breathing-A mechanical heart stimulating a sleepy brain.

Sleep-disordered breathing, including obstructive sleep apnea (OSA) and central sleep apnea (CSA), is common in severe heart failure (HF) patients. There is limited data on the effect of left ventricular assist devices (LVAD) on sleep apnea.

A Rocky Discontinuation of Diet Mountain Dew.

A 62-year-old man with a past medical history of recently diagnosed type II diabetes mellitus presented for multiple episodes of nephrolithiasis after stopping Diet Mountain Dew ingestion.

Unilateral nipple discharge in a man without a palpable mass diagnosed as breast cancer.

A 69-year-old man without a family history of breast cancer presented to his primary care physician with a 1-year history of clear, unilateral nipple discharge (ND) without an associated palpable breast mass. His laboratory findings were significant for hyperprolactinaemia at 28 ng/mL. Diagnostic work up including mammography, ultrasound and core needle biopsy ultimately revealed a ductal carcinoma in situ and a rare papillary variant of invasive ductal carcinoma.
