Encapsulated Beta-Islet Cells As A Bioartificial Pancreas To Treat Insulin-Dependent Diabetes During Pregnancy, Stephen Hunter, Y. Wang, C. Weiner, Jennifer Niebyl
Jennifer R Niebyl
OBJECTIVE: Our purpose was to determine the effectiveness of the bioartificial pancreas technique in correcting (1) maternal carbohydrate metabolism and (2) fetal malformation rates in a pregnant diabetic animal model. STUDY DESIGN: Insulin secretion from encapsulated rat islets cultured in the presence of homologous rat prolactin was determined and compared with that of controls. Streptozotocin-induced diabetic Balb/c mice were then transplanted with rat islet cells encapsulated within alginate microbeads and were then bred. Blood glucose determinations were made after transplantation and throughout gestation. Pups were delivered by cesarean section on day 19 of gestation. Outcome parameters from the transplanted study …

Oral Hypoglycemic Agents In Pregnancy, N. Tran, Stephen Hunter, J. Yankowitz

Pregnancies in diabetic women are associated with increased risk of spontaneous abortion, congenital malformations, preeclampsia, preterm labor, macrosomia, shoulder dystocia, and cesarean section. Advances in antepartum cares and strict adherence to dietary and insulin regimens have been shown to significantly reduce the rate of maternal morbidity as well as perinatal morbidity and mortality. Historically, reports of potential fetal teratogenicity and hypoglycemic effects on the fetus contraindicated the use of oral hypoglycemic agents in pregnancies complicated with either type II diabetes mellitus (DM) or gestational diabetes mellitus (GDM). Recently, physicians increasingly prescribe newer generations of oral hypoglycemic agents to treat GDM …

Many women with diabetes notice changes in glucose control perimenstrually. To describe the pattern of changes in glucose control throughout the complete menstrual cycle, and the reproducibility of these changes, we performed a pilot study evaluating glycemic profiles continuously for three cycles in four women with type 1 diabetes. All participants had hemoglobin A1c <7.5% and regular menstrual periods off oral contraceptives. They used Medtronic MiniMed (Northridge, CA) Continuous Glucose Monitoring System (CGMS) devices continuously for three complete menstrual cycles, checked capillary glucose measurements six times daily, changed their own sensors every 3 days, and were seen seven times per …

BACKGROUND: Systemic disease and hormonal changes have been implicated as complicating factors for periodontal disease. Diabetes has been identified as a risk factor for periodontal disease, and diabetics can experience periodontal destruction at an earlier age than non-diabetic individuals. Increased hormone levels during pregnancy can contribute to increased gingival inflammation. The purpose of this study was to examine the association of type 1 diabetes mellitus (DM) on the periodontal status of pregnant women. METHODS: Thirty-three (13 diabetic and 20 non-diabetic) subjects, 20 to 39 weeks gestation, participated in this study. The mean age of the diabetics and non-diabetics was 28.5 …

Present And Future Perspectives On The Use Of Free Or Encapsulated Pancreatic Islet Cell Transplantation As A Treatment Of Pregnancy Complicated By Type 1 Diabetes, Stephen Hunter
Stephen K. Hunter
Pregnancies complicated by insulin-dependent diabetes mellitus (IDDM) pose significant health risks to both the mother and her developing fetus. Congenital malformations in the offspring of diabetic mothers have an incidence which is 2-5 times that seen in the background. Euglycemia in the first trimester of pregnancy can reduce this incidence, but achieving euglycemia with conventional exogenous insulin therapy is both costly and difficult. Even with intense insulin dosage adjustments, the blood glucose profile of the diabetic pregnant patient does not mimic that seen in nondiabetic patients. Both the difficulties and inadequacies of conventional therapy for IDDM-complicated pregnancy provide a stimulus …

OBJECTIVE: In this pilot study, we evaluated the impact of providing patients with a literacy-appropriate diabetes education guide accompanied by brief counseling designed for use in primary care. METHODS: We provided the Living with Diabetes guide and brief behavior change counseling to 250 English and Spanish speaking patients with type 2 diabetes. Counseling sessions using collaborative goal setting occurred at baseline and by telephone at 2 and 4 weeks. We measured patients' activation, self-efficacy, diabetes distress, knowledge, and self-care at baseline and 3-month follow-up. RESULTS: Statistically significant (p

OBJECTIVE: To examine academic achievement in children with diabetes and to identify predictors of achievement. RESEARCH DESIGN AND METHODS: Participants were 244 children, ages 8-18 years, with type 1 diabetes. Measures included school-administered standardized achievement tests (Iowa Tests of Basic Skills and Iowa Tests of Educational Development [ITBS/ITED]), grade point averages (GPAs), school absences, behavioral assessment, age at disease onset, hospitalizations, and HbA(1c). Statistical differences between subgroups of children were evaluated using t test and ANOVA, statistically controlling for socioeconomic status. Regression analyses were carried out to examine predictors of academic performance. RESULTS: Reading scores and GPA were lower for …

OBJECTIVE: Subtle neuropsychological deficits have been found in some children with type 1 diabetes. However, these data have been inconsistent, and it is not clear what the impact of these deficits might be on the learning of children with diabetes over time. The purpose of this study was to determine whether type 1 diabetes significantly interferes with the development of functional academic skills. It was hypothesized that 1) children with type 1 diabetes would demonstrate deficits in academic performance and behavior when compared with sibling or classmate control subjects and 2) that academic performance in children with type 1 diabetes …

Proportional hazards analyses assume that the magnitude of mortality risk for a predictor variable remains proportional over time. In a time-dependent model, the explanatory variable violates this assumption, and repeat observations are required to accommodate the change in risk that occurs over time. Using a retrospective cohort design, we tested the following laboratory values for a time-by-covariate interaction: hematocrit (HCT), serum albumin (ALB), and serum creatinine (CR). A random sample of 4,083 hemodialysis patients whose specimens were analyzed in a central laboratory over a 3-year period served as the study group. Using the baseline observation, we discovered significant probability values …
