Filter by:The goal of this observational study is to compare fetal liver ultrasound radiomics between pregnancies complicated by type 1 diabetes and healthy controls. The main questions it aims to answer are: - Are fetal liver ultrasound radiomic features reproducible? - Does fetal liver ultrasound radiomics differ between pregnancies complicated by type 1 diabetes and healthy controls? Participants will undergo ultrasound examination to collect ultrasound data for the analyses.
The primary objective of the study is to assess metabolic plasma markers of insulin resistance in patients with early-stage HER2-negative breast cancers receiving dapagliflozin concomitant with neoadjuvant therapy.
The study aims to investigate the relationship between fasting insulin and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) across various demographic factors, including age, sex, race/ethnicity, BMI, and polycystic ovary syndrome (PCOS) diagnosis. By analyzing these variables, the study seeks to identify potential variations in insulin levels, which could provide valuable insights into the impact of different factors on metabolic health and the development of insulin-related conditions.
In this project the investigators will test if it is possible to measure changes in intestinal gas production after supplementation of a complex fiber mixture over a 36 hour period in both lean normoglycemic individuals and individuals with insulin resistance and/or prediabetes with overweight when compared with a placebo Changes in intestinal gas production will also be related to energy expenditure, substrate metabolism, microbial composition and related metabolites in feces, blood and urine.
50% of Arizonans are diabetic or pre-diabetic resulting in $6.4 billion in health care and productivity costs. The severity and incidence of Type 2 Diabetes Mellitus (T2DM) is directly related to the hepatic lipid concentration. The degree of hepatic lipid accumulation is communicated by the hepatic vagal afferent nerve (HVAN) to regulate pancreatic insulin secretion and whole body insulin sensitivity. We have shown that obesity enhances expression of GABA-Transaminase (GABA-T) decreasing hepatic release of the excitatory neurotransmitter, aspartate, and increasing release of the inhibitor neurotransmitter, GABA. This enhanced inhibitory tone decreases hepatic vagal afferent nerve activity, increasing pancreatic insulin release and decreasing skeletal muscle glucose clearance/insulin sensitivity. Pharmacological inhibition of GABA-T robustly improves glucose homeostasis in diet induced obese mice. We propose 2 clinical objectives that will test the effect of GABA-T inhibition on glucose tolerance and insulin sensitivity in obese, hyperglycemic, hyperinsulinemic patients.
The purpose of this study is to continue follow up of conservatively treated CHI patients and to focus on their metabolic outcome, including frequency of hypoglycemia after discontinuing treatment and incidence of diabetes mellitus in the long term.
