We studied renal function of 194 black subjects with duration of diagnosed NIDDM from 1 month to 36 years to determine the interaction of hypertension and diabetes on nephropathy. Renal function was assessed by isotopic GFR and RPF studies, and serum creatinine. One hundred seventeen of the 194 subjects had 24-hour urinary albumin excretion (AER). AER > 300 mg/24 h correlated with longer duration of NIDDM, decrease in GFR and RPF, and rise in serum Cr, and all subjects were hypertensive. AER 30 to 300 mg/24 h also correlated with a longer duration of NIDDM and 80% had hypertension. When 194 subjects were grouped according to duration of NIDDM and the presence or absence of hypertension, subjects who remained normotensive had normal renal function. In hypertensive subjects a decrease in GFR occurred with duration of NIDDM > 1 year and decrease in RPF with duration of NIDDM > 5 years. In hypertensive subjects with NIDDM > 10 years, 36% had impaired renal function (GFR < 80 ml/min/1.73 m2 or serum creatinine > 1.4 mg/dl) and 75% had microalbuminuria or clinical proteinuria. Within this group, those subjects who developed hypertension after their diagnosis of diabetes were likely to have evidence of nephropathy as compared to those subjects whose hypertension was diagnosed prior to or simultaneous with their diabetes: 17 of 20 (85%) versus 7 of 13 (54%), respectively (P = 0.05). These data provide insight into the relationship between hypertension and diabetes in the development of nephropathy in black NIDDM individuals.

Hospitalized patients who meet specific criteria at discharge are referred to the transitional care clinic team consisting of a nurse practitioner and/or physician and a clinical pharmacist. In collaboration with the providers, the pharmacist reviews medications for appropriateness, assesses adherence, recommends medication changes and provides education. The purpose of this study was to measure the effect of an outpatient transitional care clinical pharmacist on 30-day re-admissions in an urban setting serving a population of low socioeconomic status. After receiving IRB approval, this single-center retrospective study analyzed records of 573 patient visits of which nearly 75% included a clinical pharmacist interaction. Rates of 30-day re-admissions were not statistically different among the two groups, however, it was found that each added co-morbidity significantly increased the patients' 30-day re-admission rate by 26%.

The effect of varying the size of a meal on plasma insulin was determined in eight normal male adults. The effect of consuming one half of a meal at 0 time and one half at two hours later was also studied. Each subject was studied on four days, one day when he consumed a whole meal (580 calories) of natural foodstuffs; one day, one-half the meal; one day, one quarter of the meal, and one day when he consumed one half the meal at 0 time and the remainder two hours later. When fractions of the meals were ingested, all ingredients were decreased proportionately. As meal size was increased, a log-dose relationship was observed to characterize the comparison of meal size ingested to plasma insulin response. When on the fourth day the subjects consumed the meal in fractions, the mean sum of the plasma insulin responses was identical to that observed when the meal was eaten at one time. The results suggest that over a four-hour period, the plasma insulin response is a function of the magnitude of the load of calories requiring disposition and that the response does not appear to be influenced by the frequency with which the calories are ingested.
