For one thing, a gene called Dusp8 is linked with an increased risk for diabetes. This gene codes for a protein that regulates neuronal signaling in the hypothalamus. Also, infusions into the hypothalamus of a hormone called leptin normalize blood glucose and diminish insulin resistance in diabetic animals. Activation of hypothalamic cells by leptin has an important role in maintaining normal levels of blood glucose. Thus, both the endocrine cells of the pancreas AND cells in the hypothalamus may have a role in the etiology of type 2 diabetes. Hypothalamic cells regulate blood glucose via projections to the autonomic nervous system. Autonomic innervation of liver and muscle cells stimulates an increased uptake of glucose. In diabetic humans, the control of blood glucose by the autonomic nervous system is abnormal. Leptin-sensitive, glucose regulating neurons become resistant to leptin during aging or during exposure to a high-fat diet. These leptin resistant neurons fail to restrain food intake, obesity, and blood glucose. The reasons for this lowered responsiveness to leptin are uncertain and are part of the puzzle of the causes of type 2 diabetes.Blood glucose levels can also be normalized in diabetic rodents by a single intrahypothalamic infusion of Fibroblast Growth Factor 1 (FGF1), an effect that persists for months even in severely diabetic animals. This remarkable cure of diabetes is accomplished by a stimulation of accessory brain cells called astrocytes.
The report found that those with acute inflammation of the gallbladder can be surgically treated in the acute phase, within a few days of symptom debut, without increasing the risk for complications (compared to when the surgery is done later in an asymptomatic stage). Epidemiology
The annual risk of developing biliary colic is 2 to 3%. References
