Differentiating Demographic Factors In Latino Patients With Type 2 Diabetes, Carol Lynne Manning

Walden Dissertations and Doctoral Studies

The American Diabetes Association (ADA) data suggest that Latinos share a greater burden of disease than do non-Latino Whites with type 2 diabetes. As a result of poor glycemic control, Latinos also suffer consequences such as blindness, kidney disease, and limb amputation more often than do other ethnic groups. The purpose of this study was to compare demographic factors of Latinos with well-controlled type 2 diabetes, as measured by a HgbA1c of 7 or less (n = 118) to Latinos not well controlled (n = 105). This cross sectional study used a secondary data set with a sample selected from …

Albumin Levels In Hispanic Dialysis Patients With And Without Type Ii Diabetes, Hector Hernandez

Walden Dissertations and Doctoral Studies

Albumin provides the vital scaffolding for growth and tissue repair and supports oncotic blood pressure and hemodynamics. In hemodialysis patients, albumin aids with fluid removal by drawing excess fluid from edematous tissues back into the blood where it can then be removed by a dialyzer. The hyperglycemia seen in dialysis patients with Type II diabetes progressively damages kidney glomeruli, which permits albumin seepage into the urine, thus lowering serum albumin. The conceptual framework underpinning this research is the van't Hoff theory of osmotic pressure. Under this framework, the solute-solvent relationship largely contributes to the osmotic movement of fluid. The purpose …
