SUBJECTS AND METHODS:This study included 2 groups, Group-1(cases) consists of 120 obese females and Group-2 (controls) consists of 30 non-obese females. The included females were subjected to full clinical examination, anthropometric measurements and Kendrick Battery for evaluation of cognitive functions (short term memory and attention). Evaluation of serum Vitamin D, Parathyroid hormone, C-peptide and fasting blood glucose were done. The obese group was put on a balanced low caloric diet (900-1000 K Calories/day) for 2 months, where reevaluation was performed.
RESULTS:Comparing obese group with non-obese control group revealed significant lower mean level of serum vitamin D associated with significant lower cognitive functions test and higher fasting blood glucose. After 2 months of low caloric diet, a significant increase in the serum level of vitamin D, accompanied with improvement in cognitive functions and decrease in fasting blood glucose and improved insulin resistance was seen. A correlation is found between vitamin D serum level and cognitive functions.CONCLUSION: A lower vitamin D serum level could be a modifiable risk factor for obesity, insulin resistance and cognitive impairment in middle age females.
BACKGROUND: Metabolic diseases are known to be risk factors of kidney injury. The glycoprotein Uromodulin Tamm-Horsfall protein is a biochemical marker specifically synthesized and secreted by kidney tubular epithelial cells.
AIM: The study aimed to use novel biochemical parameters to predict early changes in renal functions and to use natural food supplements to help in the prevention and management of such conditions.
METHODS: Crossover studies comparing two interventions trials. Subjects: Seventy obese females were included in this study. They were divided in two groups, first group (34 women) with mean age 45.82 ± 1.51 and mean body mass index (BMI) 35.65 ± 0.68 kg/m2, and second group (36 women) with mean age 49.80 ± 2.27, and mean BMI 37.67 ± 1.59. Intervention: All participants have followed a low caloric balanced regimen (1000–1200 Kcal/day) of the each groups consumed a different specific nutritional supplement composed mainly of whole grains and herbs. All patients were monitored clinically, anthropometrically, dietary 24 h recall and biochemically.
RESULTS: After intervention all the recorded anthropometric parameters showed significant decreases at p ≤ 0.05–0.01. The serum uromodulin (sUMOD) increased significantly after intervention in both groups the increments were 15.56 and 9.37%. Numerically creatinine and urea decreased, while creatinine clearance increased.
CONCLUSION: Data revealed the importance of using dietary therapy composed of hypocaloric diet with supplements made from whole grains and special herbs in management of obesity and its metabolic disorders. sUMOD proved to be an accurate biochemical marker that showed the kidneys’ response to the management in comparison to using usual diagnostic markers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
