BACKGROUND: Little is known on the bacteriological profile of consecutive urine samples in elderly patients institutionalized in nursing homes. AIM: This retrospective study aims to characterize urinary pathogens, rates of isolation of the same pathogen in subsequent urine samples and predicting factors associated with such repeated isolations. Data were retrospectively retrieved from medical charts of nursing home patients during a four-year period. The authors looked for changes in rates of positive cultures, changes in urine flora, in rates of repeated isolation of the same pathogens and the possible interrelations with the use of antibiotics. METHODS: A total number of 3229 urine cultures were studied, 1311 of which (43%) were positive and 493 out of these positive cultures (37.6%) were treated with antibiotics. The rates of positive cultures increased consistently during the study period (p=0.003). E. coli (68.1%), Klebsiella pneumoniae and Proteus mirabilis accounted for more than 90% of positive cultures. RESULTS: There was no difference with regard to pathogen types isolated from symptomatic or asymptomatic cases. The rates of recurrent bacteriuria, by the same pathogen isolated at baseline urine culture, were similar in treated and untreated cases. A regression analysis aiming to predict factors associated with subsequent positive cultures had negative results, except for cases of untreated bacteriuria with pseudomonas (CI 1.36-7.09, O.R. 3.11, p=0.006). CONCLUSION: Our data support earlier studies underscoring the need to carefully consider the role of antibiotics and for better clinical guidelines for the treatment of bacteriuria in this population.

Background: Knowledge about the changes in skeletal muscle mass in nursing home residents is very limited. We hypothesized that such patients have different types of skeletal muscle mass abnormalities that may affect mortality rates. Therefore, the objective of this study was to evaluate the prevalence and extent of skeletal muscle mass decline, its different clinical phenotypes (sarcopenia, wasting/atrophy and cachexia) and the mortality rates associated with these abnormalities. Methods: A retrospective chart-review study comprising 109 institutionalized nursing home residents. Body mass index, body fat mass, fat free mass, skeletal muscle mass and survival rates were assessed. Results: Skeletal muscle mass abnormalities were found among 73 out of 109 (67.0%) patients and were more prevalent in males compared with females (97.8% and 43.8%, respectively, p<0.001). Most of these patients had muscle wasting/atrophy (51.4%) or sarcopenia (40.3%), and 9.7% suffered from cachexia. One third of the patients with abnorrmal skeletal muscle mass showed a moderate decline of skeletal muscle mass (34.7%) while the remainder (65.3%) had very low levels of skeletal muscle mass. Each group was characterized by typical medical conditions associated with skeletal muscle mass abnormality. A Kaplan-Meier survival plot of mortality showed only lower one-year survival rates in the group with sarcopenia (60%) and muscle atrophy or cachexia (53%), compared with elderly participants with a normal skeletal muscle mass (73%), (p<0.0001). There were no significant differences in 1-year mortality rates between patients with abnormal skeletal muscle mass (whether sarcopenia, cachexia or wasting). Conclusion: About two thirds of nursing home patients show skeletal muscle mass abnormalities, most within the range of very low skeletal muscle mass rather than moderately low skeletal muscle mass, that are associated with shorter survival rates, compared with normal skeletal muscle mass patients.

Objectives: To study differences in nutritional status and body composition, by feeding modality, among disabled nursing home residents. Design: A retrospective chart-review study. Setting: A nursing wing of a public urban geriatric center. Participants: Three groups of patients: non-dysphagic, orally-fed dysphagic and percutaneous endoscopic gastrostomy -fed dysphagic patients. Intervention: Standard nursing care Measurements: Basal metabolic rate, total energy expenditure and nitrogen balance under oral or percutaneous endoscopic gastrostomy feeding. Dietary intake was assessed during a 3-days period by daily-food intake protocols and a 24-hours urinary creatinine excretion to detect nitrogen balance and calculate body composition parameters. Results: Data of 117 patients (55.5% females), mean age 84.6±7.5 (range 66-98 years) was analyzed. Dysphagic patients (60) differed from non-dysphagic patients (57) by lower body mass index (p=0.020), fat mass index (p=0.017), daily protein intake (p<0.0001), daily energy intake (p<0.001), protein related energy intake (p<0.001) and a negative nitrogen balance (p<0.001). In regression analyses, dysphagia was associated with increased risk of having a body mass index lower than 22.0kg/m2 (OR=2.60, 95% CI 1.135-5.943), a negative nitrogen balance (OR=2.33, 95% CI 1.063-4.669), a low fat mass index (OR=2.53, 95% CI 1.066-6.007), and low daily protein and energy intakes per body weight (OR=2.87, 95% CI 1.316-6.268 and OR=2.99, 95% CI 1.297-6.880). Compared with orally-fed dysphagic patients (21pts.), percutaneous endoscopic gastrostomy -fed patients (39pts.) received an additional mean energy intake of 30.5% kcal per day and mean protein intake of 26.0%. This additional intake was not associated with improved body composition parameters (such as fat free mass, skeletal mass or body mass index). Conclusion: Dysphagic nursing home residents are characterized by worse nutritional, metabolic and body composition parameters, compared with non-dysphagic residents. Body composition parameters did not differ between orally-fed and percutaneous endoscopic gastrostomy-fed dysphagic patients, despite significantly better nutritional and metabolic parameters in PEG-fed patients. Other approaches (perhaps physical training, pharmacological etc.) should be sought to improve body composition of such patients. © 2013 Serdi and Springer Verlag France. Source
