Calcific uremic arteriolopathy, otherwise known as calciphylaxis, is a rare disease characterized by skin ulceration and tissue necrosis, likely the result of vascular calcification with accompanying intimal hypertrophy and small vessel thrombosis. Although most often associated with end-stage renal disease, it has also been seen in a number of other disorders (collectively referred to as nonuremic calciphylaxis). The purpose of this review is to summarize and analyze the currently available literature regarding the pathophysiology, risk factors, clinical presentation, diagnostic features and treatment modalities for this exceptionally uncommon illness. A series of recommended treatments is proposed for optimal treatment of calciphylaxis lesions.

Diabetes mellitus increases the susceptibility to infection by altering both the innate and the adaptive immune systems. Hyperglycemia has been associated with adverse outcomes in hospitalized patients, especially critically ill patients; these poor outcomes are explained in part by hospital-associated infections. ⋯ In summary, acute hyperglycemia can significantly alter innate immune responses to infection, and this potentially explains some of the poor outcomes in hospitalized patients who develop hyperglycemia.

Our purpose was to investigate the relationship between oxygen saturation (SpO2) and dynamic interstitial glucose level (IGL) in patients with obstructive sleep apnea (OSA) along with type 2 diabetes mellitus (T2DM), and to investigate the potential mechanisms thereof. ⋯ Severe and moderate OSA with T2DM is marked by a delayed IGL peak following LSpO2. Nocturnal hypoxemia causes hyperglycemia in patients with OSA along with T2DM.

Pulse wave velocity is a marker of arterial stiffness. Unequal arterial stiffness has been associated with increased risk of cardiovascular events. This study calculated bilateral brachial-ankle pulse wave velocity (baPWV) differences and investigated the associations of unequal bilateral baPWV with overall and cardiovascular mortality in patients receiving hemodialysis (HD). ⋯ ΔbaPWV was associated with an increased risk of cardiovascular and overall mortality in patients receiving HD. Earlier evaluation of ΔbaPWV may facilitate the identification of patients receiving HD who have an increased risk of cardiovascular and overall mortality.
