BACKGROUND: Many older adults with cancer have at least one comorbidity. Type II diabetes mellitus (T2DM) is a common comorbidity among patients with prostate cancer (PC) and represents an important consideration in this population. Comorbid T2DM can negatively impact cancer-specific outcomes for patients, suggesting the need for better glycemic management, especially for patients on active cancer treatment. The goal of this modified Diabetes Self-Management Education Services (mDSMES) pilot study was to provide patients with the opportunity to learn methods of diabetes self-management, including how to manage their glucose levels, improve their understanding and utilization of medication to promote improvements in …

This case study highlights the application of seizure fingerprint analysis in the source-space of stereo-EEG (SEEG) data to accurately localize the epileptogenic zone (EZ) in patients with complex cortical malformations. A 25-year-old female with extensive bilateral perisylvian polymicrogyria (PMG) presented with intractable focal seizures. The source-level analysis performed in Brainstorm using the sLORETA imaging algorithm subsequently showed EZ fingerprint analysis. The patient underwent MR-guided laser interstitial thermal therapy (LITT), targeting the identified EZ, resulting in postoperative seizure freedom with minimal complications. Extending the analysis from the sensor-space to the source-space could further enhance surgical planning and improve outcomes in complex …

BACKGROUND: South African women of childbearing age are disproportionally affected by obesity and at significant risk of Type 2 Diabetes Mellitus (T2DM). Unless pregnant, they do not readily undergo screening for T2DM. With a local focus on improved antenatal care, hyperglycemia is often first detected in pregnancy (HFDP). This may erroneously be attributed to Gestational Diabetes Mellitus (GDM) in all without considering T2DM. Glucose evaluation following pregnancy is essential for early detection and management of women with T2DM in whom persistent hyperglycemia is to be expected. Conventional testing with an oral glucose tolerance test (OGTT) is cumbersome, prompting investigation for …

Few studies have demonstrated reproducible gene-diet interactions (GDIs) impacting metabolic disease risk factors, likely due in part to measurement error in dietary intake estimation and insufficient capture of rare genetic variation. We aimed to identify GDIs across the genetic frequency spectrum impacting the macronutrient-glycemia relationship in genetically and culturally diverse cohorts. We analyzed 33,187 participants free of diabetes from 10 National Heart, Lung, and Blood Institute Trans-Omics for Precision Medicine program cohorts with whole-genome sequencing, self-reported diet, and glycemic trait data. We fit cohort-specific, multivariable-adjusted linear mixed models for the effect of diet, modeled as an isocaloric substitution of carbohydrate …

BACKGROUND/AIMS: Markers to clinically evaluate structural changes from diabetic retinal neurodegeneration (DRN) have not yet been established. To study the potential role of peripapillary retinal nerve fibre layer (pRNFL) thickness as a marker for DRN, we evaluated the relationship between diabetes, as well as glycaemic control irrespective of diabetes status and pRNFL thickness.

METHODS: Leveraging data from a population-based cohort, we used general linear mixed models (GLMMs) with a random intercept for patient and eye to assess the association between pRNFL thickness (measured using GDx) and demographic, systemic and ocular parameters after adjusting for typical scan score. GLMMs were also …

BACKGROUND: Emerging data suggest that type 2 diabetes mellitus (T2D) is associated with an increased risk for fractures despite relatively normal or increased bone mineral density (BMD). Although the mechanism for bone fragility in T2D patients is multifactorial, whether glycemic control is important in generating this impairment in bone metabolism remains unclear. The purpose of our study is to identify a hemoglobin A1c (A1c) threshold level by which reduction in bone turnover begins in men with T2D.

METHOD: A cross-sectional analysis of baseline data was obtained from 217 men, ages 35-65, regardless of the presence or absence of hypogonadism or …


After Avandia: The Use Of Antidiabetic Drugs In Patients With Heart Failure, Khaled I Khalaf, Heinrich Taegtmeyer Jan 2012

After Avandia: The Use Of Antidiabetic Drugs In Patients With Heart Failure, Khaled I Khalaf, Heinrich Taegtmeyer

The Texas Heart Institute Journal

Managing diabetes mellitus is an ongoing concern, especially in the presence of heart failure. Recent reports have drawn attention to adverse cardiovascular events associated with the use of thiazolidinediones, including rosiglitazone (Avandia). In 2011, the U.S. Food and Drug Administration implemented a stringent “restricted access program” for the prescription of Avandia. Other studies, which have revealed increased mortality rates in association with tight glycemic control, raise serious concerns about managing diabetes in heart-failure patients.

Herein, we provide a perspective on the management of noninsulin-dependent diabetes in patients with heart failure. We point out that thiazolidinediones exert their major effects through …
