An analysis of the survival outcomes of simultaneous pancreas and kidney transplantation compared to live donor kidney transplantation in patients with type 1 diabetes: a UK Transplant Registry study

Transplant options for patients with type 1 diabetes and end‐stage renal disease (ESRD) include deceased donor kidney, live donor kidney (LDK) and simultaneous pancreas‐kidney (SPK) transplantation. The aim of this study was to compare outcomes between LDK and SPK for patients with type 1 diabetes and ESRD in the UK. Data on all SPK (n = 1739) and LDK (n = 385) transplants performed between January 2001 and December 2014 were obtained from the UK Transplant Registry. Unadjusted patient and kidney graft survival were calculated using the Kaplan–Meier method. Multivariate analysis of kidney graft and patient survival was performed using Cox proportional hazards regression. There was no significant difference in patient (P = 0.435) or kidney graft survival (P = 0.204) on univariate analysis. On multivariate analysis there was no association between LDK/SPK and patient survival [HR 0.71 (0.47–1.06), P = 0.095]. However, LDK was associated with an overall lower risk for kidney graft failure [HR 0.60 (0.38–0.94), P = 0.025]. SPK recipients with a functioning pancreas graft had significantly better kidney graft and patient survival than LDK recipients or those with a failed pancreas graft. SPK transplantation does not confer an overall survival advantage compared to LDK. However, those SPK recipients with a functioning pancreas have significantly better outcomes.     

Increasing the number of biopsy cores improves the concordance of biopsy Gleason score to prostatectomy Gleason score

OBJECTIVE: To evaluate taking more biopsy cores for predicting the radical prostatectomy (RP) Gleason score compared with the biopsy Gleason score, as although random sextant biopsies are the standard for a tissue diagnosis of prostate cancer, and taking more biopsies increases the detection rate, it is uncertain whether taking more cores improves the prediction of the RP Gleason score. PATIENTS AND METHODS: We analysed retrospectively 404 patients from three centres (Seattle 162, Washington 107 and Chicago 135) who had RP for prostate cancer. Six, eight or 10 biopsies were taken based on the physician's preference and the patient's characteristics. RESULTS: Before RP, 158 (39%) patients had six, 65 (16%) had eight and 181 (45%) had 10 biopsy cores taken. The accuracy of the Gleason sum of the three groups was 65/158 (41%), 26/65 (40%) and 104/181 (57.5%), respectively (P < 0.004, 10-core vs six-core). However, when comparing the Gleason score separately (i.e. 4 + 3 is not equal to 3 + 4), the accuracy of the three groups was 48/158 (30%), 20/65 (31%), and 95/181 (52.5%), respectively (P < 0.001, 10-core vs six core). CONCLUSIONS: Taking more biopsy cores improves the accuracy of the biopsy Gleason score in predicting the final Gleason score at RP; the predictive accuracy of the final Gleason score may be increased from 41% to 58% by increasing the number of biopsies from six to 10.

The significance of the gastric secretory state in gastroesophageal reflux disease

The gastric secretory status of 75 patients with abnormal esophageal exposure to gastric juice proved by 24-hour pH monitoring was measured to study the significance of gastric hypersecretion in gastroesophageal reflux disease. Gastric hypersecretion was a less-frequent finding than a mechanically defective sphincter (28% vs 72%, respectively). Forty-eight percent of patients with a normal sphincter, compared with 20% of those with a defective sphincter, were hypersecretors. In the presence of normal gastric secretion, complications occurred in 18% of those with a normal sphincter and 77% of those with a defective sphincter. In the presence of hypersecretion, the complication rate was 40% and 82%, respectively. These findings show that the development of reflux complications are related to a defective sphincter. Gastric hypersecretion in reflux patients with a normal sphincter is best treated by acid reduction using H2 blockers. Patients with a mechanically defective sphincter, regardless of their gastric secretory state, should have an antireflux procedure.     

Evaluating Components of Dental Utilization among Adults with Diabetes and Matched Controls via Hurdle Models

ABSTRACT: BACKGROUND: About one-third of adults with diabetes have severe oral complications. However, limited previous research has investigated dental care utilization associated with diabetes. This project had two purposes: to develop a methodology to estimate dental utilization using claims data and to use this methodology to compare utilization of dental care between adults with and without diabetes. METHODS: Data included secondary enrollment and demographic data from Washington Dental Service (WDS) and Group Health Cooperative (GH), clinical data from GH, and dental-utilization data from WDS claims during 2002-2006. Dental and medical records from WDS and GH were linked for enrolees continuously and dually insured during the study. We employed hurdle models in a quasi-experimental setting to assess differences between adults with and without diabetes in 5-year cumulative utilization of dental services. Propensity score matching adjusted for differences in baseline covariates between the two groups. RESULTS: We found that adults with diabetes had lower odds of visiting a dentist (OR=0.74, p < 0.001). Among those with a dental visit, diabetes patients had lower odds of receiving prophylaxes (OR=0.77), fillings (OR=0.80) and crowns (OR=0.84) (p < 0.005 for all) and higher odds of receiving periodontal maintenance (OR=1.24), non-surgical periodontal procedures (OR=1.30), extractions (OR=1.38) and removable prosthetics (OR=1.36) (p < 0.001 for all). CONCLUSIONS: Patients with diabetes are less likely to use dental services. Those who do are less likely to use preventive care and more likely to receive periodontal care and tooth-extractions. Future research should address the possible effectiveness of additional prevention in reducing subsequent severe oral disease in patients with diabetes.
