Cause of death in 1144 patients with diabetes mellitus: an autopsy study.

The pathological reports for all patients over 13 years of age who had had an autopsy at one of three university-affiliated hospitals between 1967 and 1976 were reviewed to determine the principal cause of death. The clinical records of the patients with diabetes were reviewed to verify the diagnosis and to determine the known duration of diabetes. There were 1144 patients with diabetes mellitus and 5674 without. The sex distribution was similar in the two groups. The patients with diabetes were slightly older, males by 2.2 years and females by 3.2 years. Disease of the circulatory system was the principal cause of death in males (53.7%) and females (58.9%) with diabetes. The rates in the corresponding patients without diabetes were 37.6% and 35.2%. Neoplasms accounted for 18.9% of deaths in males with diabetes, compared with 35.7% in males without diabetes; the corresponding figures in females were 16.0% and 39.4%. Renal disease accounted for 5.9% of deaths in patients with diabetes.

Modulatory effects of parallel fiber and molecular layer interneuron synaptic activity on purkinje cell responses to ascending segment input: a modeling study.

Based on anatomical, physiological, and model-based studies, it has been proposed that synapses associated with the ascending segment of granule cell axons provide the principle excitatory drive on Purkinje cells which is then modulated by the more numerous parallel fiber synapses. In this study we have evaluated this idea using a detailed compartmental model of a cerebellar Purkinje cell by providing identical ascending segment synaptic inputs during different levels of random parallel fiber and molecular interneuron input. Results suggest that background inputs from parallel fibers and molecular layer interneurons can have a substantial effect on the response of Purkinje cells to ascending segment inputs. Interestingly, these effects are not reflected in the average firing rate of the Purkinje cell and are thus entirely dendritic in effect. These results are considered in the context of the known segregated spatial distribution of the parallel fibers and ascending segment synapses and a new hypothesis concerning the functional organization of cerebellar cortical circuitry.
