Objective: To evaluate the accuracy of the defining characteristics of the excess fluid volume nursing diagnosis of NANDA International, in patients undergoing hemodialysis., Method: This was a study of diagnostic accuracy, with a cross-sectional design, performed in two stages. The first, involving 100 patients from a dialysis clinic and a university hospital in northeastern Brazil, investigated the presence and absence of the defining characteristics of excess fluid volume. In the second step, these characteristics were evaluated by diagnostic nurses, who judged the presence or absence of the diagnosis. To analyze the measures of accuracy, sensitivity, specificity, and positive and negative predictive values were calculated. Approval was given by the Research Ethics Committee under authorization No. 148.428., Results: The most sensitive indicator was edema and most specific were pulmonary congestion, adventitious breath sounds and restlessness., Conclusion: The more accurate defining characteristics, considered valid for the diagnostic inference of excess fluid volume in patients undergoing hemodialysis were edema, pulmonary congestion, adventitious breath sounds and restlessness. Thus, in the presence of these, the nurse may safely assume the presence of the diagnosis studied.

Objectives: to identify adaptation problems under Roy's Model in patients undergoing hemodialysis and to correlate them with the socioeconomic and clinical aspects., Method: a transversal study, undertaken using a questionnaire. The sample was made up of 178 individuals. The Chi-squared and Mann-Whitney U tests were undertaken., Results: the adaptation problems and the socioeconomic and clinical aspects which presented statistical associations were: Hyperkalemia and age; Edema and income; Impairment of a primary sense: touch and income; Role failure and age; Sexual dysfunction and marital status and sex; Impairment of a primary sense: vision and years of education; Intolerance to activity and years of education; Chronic pain and sex and years of education; Impaired skin integrity and age: Hypocalcemia and access; Potential for injury and age and years of education; Nutrition below the organism's requirements and age; Impairment of a primary sense: hearing and sex and kinetic evaluation of urea; Mobility in gait and/or coordination restricted, and months of hemodialysis; and, Loss of ability for self-care, and months of hemodialysis and months of illness., Conclusion: adaptation problems in the clientele undergoing hemodialysis can be influenced by socioeconomic/clinical data. These findings contribute to the development of the profession, fostering the nurse's reflection regarding the care.

Background: Diabetes and cardiovascular disease have emerged as key threats to human health, and the risk is increased in individuals with visceral obesity. The consensus is that physical exercise should be part of the treatment of diabetes mellitus (DM)., Objective: To compare the influence of guided and structured physical exercise programs (SPEP), three to five times per week, during a period of 20 weeks, on glycemic control and body composition of type 2 diabetic patients (DM2)., Methods: The research was conducted at the Universidade Federal de São Paulo (Federal University School of Medicine in São Paulo). At the clinical visit, patients from the Control Group (CG) n=17, mean age 55.8 years, were encouraged to engage in a physical exercise program. Patients from Group 3x (G3), n=14, mean age 57.4 years, were to engage in 1 hour of physical exercise, 3x/week, and Group 5x (G5), n=9, mean age 58.8 years, followed the same protocol but 5x/week. Mean of 5 years since diagnosis in all groups. Classes consisted of a 5-minute warm-up, 30-minute treadmill walk at 70% of maximum heart rate, and 10-minute relaxation. BMI, abdominal circumference (AC), percentage of body fat (BF), capillary glycemia (CG), fasting glycemia (FG), and glycated hemoglobin (HbA1c) were assessed., Results: A comparison was made between the baseline time point (B) and the 20th week (20th). BMI in G3 (B:29.5+/-2.9 vs. 20th: 28.3 +/- 2.2 Kg/sqm, p=0.005) and G5 (B:29.7+/-4.4 vs. 20th: 29.1 +/- 4.3 Kg/sqm, p=0.025); abdominal circumference in G5 (B:100.5+/-11.9 vs. 20th: 933 +/- 11.7 cm, p=0.001); BF in G3 (B:31+/-5.1 vs 20th: 26+/-5%, p=0.001) and G5 (B:32.4 +/- 5.4 vs. 20th: 30.3 +/- 6.9%, p=0.001); FG, G5 (B:150.8 +/- 47.5 vs. 20th: 109.2+/- 30.5 mg/dL, p=0.034), showed statistically significant differences. CG did not show statistically significant differences for these variables. CG showed a tendency to drop after physical exercise in G5. HbA1c showed no statistically significant differences in the three groups., Conclusion: G5 did better than G3 in most parameters assessed. However, results failed to show a decrease of HbA1c in DM2 patients.
