Hyperosmolar hyperglycaemic state as a stroke cause or stroke mimic: an illustrative case and review of literature.

Hyperosmolar hyperglycaemic state (HHS) is a life-threatening metabolic complication of type 2 diabetes (T2DM) that often presents with neurological symptoms. A 74-year-old man with known T2DM presented to the emergency department with collapse, left-sided weakness and slurred speech (National Institutes of Health Stroke Scale (NIHSS) 3) and a biochemical profile consistent with HHS. When he further deteriorated (NIHSS 20), he was managed for concurrent ischaemic stroke.

Measurement of Peak C-Peptide at Diagnosis Informs Glycemic Control but not Hypoglycemia in Adults With Type 1 Diabetes.

Context: High-residual C-peptide in longer-duration type 1 diabetes (T1D) is associated with fewer hypoglycemic events and reduced glycemic variability. Little is known about the impact of C-peptide close to diagnosis.

Objective: Using continuous glucose monitoring (CGM) data from a study of newly diagnosed adults with T1D, we aimed to explore if variation in C-peptide close to diagnosis influenced glycemic variability and risk of hypoglycemia.
