Diabetic ketoacidosis and the hyperglycemic hyperosmolar state are the most serious complications of diabetic decompensation and remain associated with excess mortality. Insulin deficiency is the main underlying abnormality. Associated with elevated levels of counterregulatory hormones, insulin deficiency can trigger hepatic glucose production and reduced glucose uptake, resulting in hyperglycemia, and can also stimulate lipolysis and ketogenesis, resulting in ketoacidosis. ⋯ Clinical diagnosis is based on the finding of dehydration along with high capillary glucose levels with or without ketones in the urine or plasma. The diagnosis is confirmed by the blood pH, serum bicarbonate level and serum osmolality. Treatment consists of adequate correction of the dehydration, hyperglycemia, ketoacidosis and electrolyte deficits.

The requirements of professionalism and the expected qualities of medical staff, including high moral character, motivate institutions to care about the ethical development of students during their medical education. We assessed progress in moral reasoning in a cohort of medical students over the first 3 years of their education. ⋯ Temporal variations in students' scores show a levelling process of their moral reasoning. This finding prompts us to ask whether a hidden curriculum exists in the structure of medical education that inhibits rather than facilitates the development of moral reasoning.

Women who live in disadvantaged circumstances in Canada exhibit dietary intakes below recommended levels, but their children often do not. One reason for this difference may be that mothers modify their own food intake to spare their children nutritional deprivation. The objective of our study was to document whether or not low-income lone mothers compromise their own diets to feed their children. ⋯ Our study demonstrates that low-income lone mothers compromise their own nutritional intake in order to preserve the adequacy of their children's diets.
