Nurse-patient perception of stressors associated with coronary artery bypass surgery
Patients undergoing coronary artery bypass surgery endure many stressors postoperatively. The purpose of this research study was to approximately replicate Puetz's study (1990) regarding the incongruencies of patient and nurse perceptions of stresser associated with coronary artery bypass surgery. …

Changes in gastrointestinal hormones, leptin, and satiety after gastric bypass surgery
The Roux-en-Y gastric bypass (RYGB) is a well-accepted tool for the treatment of obesity and compared to conventional weight loss methods (e.g. diet and exercise) and other weight loss surgeries (e.g. gastric banding), it results in considerable weight loss that is maintained long-term. Although …

A qualitative study of the perceived psychosocial outcomes of gastric bypass surgery
… lives of individuals who have undergone gastric bypass surgery for morbid obesity have (1) been guided by constructs emanating from the assumptions of researchers, and (2) have resulted in fragmented conclusions that catalogue changes without theoretically integrating them. Using unstructured and …

Quality of Life Three Months After Coronary Artery Bypass Surgery: Effects of Presurgical Physical Fitness
Coronary artery bypass grafting (CABG) is a procedure used to help improve and save the lives of thousands of coronary artery diseased patients every year. Measuring health-related quality of life (HRQL) significantly contributes to understanding patient perceptions of outcomes attributable to this …
