In order to investigate the changes produced by Type I diabetes on the ad libitum eating behavior of free-living humans, 56 French participants with diabetes and 28 healthy controls were paid to maintain detailed food intake diaries for four 7-day periods. The participants with diabetes ate more protein and more frequent meals, ate slightly later and with fewer other people, were less hungry, thirsty, and depressed, but more elated than the healthy participants. Responses to social facilitation, the diurnal rhythm, subjective hunger, the palatability of the food, and the weekend were not affected by the presence of diabetes. The participants with diabetes had significantly larger correlations and regression coefficients for the relationship between meal size and the duration of the before-meal interval. The relationship between meal size and the after-meal interval was strong and positive in all participants. The recorded behavioral characteristics of diabetics may, in part, be accounted for by the nutritional education that is provided as an integral part of treatment. Based upon these results, it was theorized that the glucose regulatory system is an influence on intake, but only one of many that are responsible for the coordination, control, and regulation of nutrient intake in free-living humans.

Our hunter-gatherer ancestors appeared to survive on little salt. When today's rural dwellers move to urban environments, they increase their salt intake and the salt-sensitive among them become prone to age-related increase in blood pressure and hypertension. This paper reviews our knowledge of the mechanisms of salt disposal and plasma volume regulation, salt consumption in human evolution, salt intake and prevalence of hypertension, and the results of interventions aimed at modulating both. Finally, it discusses current hypotheses on the mechanisms of selective pressure that may have favored the emergence of a salt-sensitive, hypertensive genotype. Similar to 'thrifty' genes, which supported energy savers in times of scarcity, but may now be causing obesity and type 2 diabetes, 'thirsty' genes, by acting on salt and water retention, might have helped individuals survive the challenge of volume-depleting illnesses, especially when combined with stress-inducing situations, but may now cause high BP and related damage in the post-reproductive age.

In this study we investigated the effects of preoperative oral carbohydrate administration on postoperative insulin resistance (PIR), gastric fluid volume, preoperative discomfort, and variables of organ dysfunction in ASA physical status III-IV patients undergoing elective cardiac surgery, including those with noninsulin-dependent Type-2 diabetes mellitus. Before surgery, 188 patients were randomized to receive a clear 12.5% carbohydrate drink (CHO), flavored water (placebo), or to fast overnight (control). CHO and placebo were treated in double-blind format and received 800 mL of the corresponding beverage in the evening and 400 mL 2 h before surgery. Patients were monitored from induction of general anesthesia until 24 h postoperatively. Exogenous insulin requirements to control blood glucose levels <or=10.0 mmol/L were used as a marker for PIR. Gastric fluid volume was measured by passive gastric reflux and preoperative discomfort using visual analog scales. Postoperative clinical and surgical data were recorded. Blood glucose levels and insulin requirements did not differ between groups. Patients receiving CHO and placebo were less thirsty compared with controls (P < 0.01 and P = 0.06, respectively). Ingested liquids did not cause increased gastric fluid volume or other adverse events. The CHO group required less intraoperative inotropic support after initiation of cardiopulmonary bypass weaning (P < 0.05). In conclusion, preoperative CHO administration before cardiac surgery does not affect PIR. Clear fluids reduce thirst and may be recommended as a safe procedure in ASA III-IV patients. Further research is indicated to investigate possible cardioprotective effects of preoperative CHO intake.

An 81-year-old man, with chronic renal failure due to chronic glomerulonephritis on maintenance hemodialysis (HD) for 4.5 years, was admitted to our hospital because of rapidly developing hyperglycemia and hypertension. He had been under good control on HD with no history of hyperglycemia. One month prior to admission he felt thirsty and generally fatigued, but did not inform medical staff of his symptoms. We diagnosed him as suffering from autoimmune pancreatitis (AIMP) associated with secondary diabetes mellitus, according to the typical feature of AIMP on endoscopic retrograde cholangiopancreatography and an elevated level of serum immunoglobulin G4 (IgG4). He was treated with insulin and a corticosteroid, following which, the diffuse narrowing of the main pancreatic duct improved and his serum IgG4 level reduced. AIMP is a rare but important complication in HD patients that requires prompt diagnosis and treatment; we are therefore reporting on a unique complication in a chronic HD patient.

A 64-years-old man referred to a hospital because of high-grade fever. He was diagnosed as having influenza B by "POCTEM Influenza A/B", a rapid influenza diagnostic kit which detect some antigens of influenza virus. Six days after medication of oseltamivir phosphate, his flu-symptoms disappeared, but he complained sever thirsty. And after 2days, he suffered from loss of consciousness and was admitted to the hospital. Laboratory data on admission showed diabetes ketoacidosis, slight elevation of HbA1c level despite sever hyperglycemia, and increase of serum amylase concentration. Anti GAD antibody and anti IA-2 antibody were not detected. Urinary C-peptide excretion was undetectable and serum C-peptide levels were also undetectable after glucagon and arginin load, suggesting disappearance of endogeneous insulin secretion. Class II HLA was susceptible to fulminant type1 diabetes. Based on these findings, we diagnosed him with fulminant type1 diabetes. In Japan, only three viruses in three cases have been reported to be the trigger in the development of fulminant type 1 diabetes. They were human herpes virus 6, herpes simplex virus and Coxsackie B3 virus. This is the fourth report of fulminant type 1 diabetes developed after the established diagnosis of viral infection and the first after influenza B virus infection. The fact that fulminant type 1 diabetes developed after the infection of such a common virus suggest that factors within host will play more important roles than virus itself in the etiology of fulminant type 1 diabetes.

Diabetes mellitus (type 1) is an autoimmune condition leading to absolute insulin deficiency resulting in hyperglycaemia and its associated manifestations. It is the most common type of diabetes seen in children, characterised by the 4Ts (toilet, thinner, thirsty, tired). The signs and symptoms can sometimes be non-specific and a delay or missed diagnosis may be catastrophic to the health of the child. Children with an established diagnosis of diabetes often present to the health service with issues such as hypoglycaemia, hyperglycaemia, or diabetic ketoacidosis. The condition requires life-long monitoring and strict control of blood glucose levels with insulin replacement therapy, with the aim of achieving an HbA1c level of 48 mmol/mol. There are often physical and psychosocial issues that arise from the diagnosis leading to poor control. Nurses working in different clinical settings play a vital role in raising suspicions of diabetes leading to timely diagnosis and rapid initiation of treatment. They are best placed to provide essential support in helping children and their families to come to terms with the diagnosis, as well as manage this chronic condition by addressing the common issues that arise in the ongoing management, with a particular emphasis on managing the various day-to-day challenges. Two case studies are included to highlight some of the challenges that nurses may encounter while managing children with diabetes.
