Introduction: Mild cognitive impairment (MCI) is characterized by subjective memory complaints and is considered an intermediate stage between normal and pathological cognitive function. The decline in cognitive function may be associated with low functional performance and alterations in body composition in older adults. Objective: To assess muscle strength, lower extremity functional performance and body composition in elderly women with MCI. Methods: Forty-three elderly women (aged 60-80 years) participated in the study. Participants were divided into two groups: elderly women with MCI (n = 19) and elderly women without MCI (n = 24). To diagnose MCI, we used the instruments proposed by Petersen et al. According to it, the subjects had to have memory complaints that had no effects on basic or instrumental activities of daily living. Muscle strength was assessed via palmar grip strength (PGS) using a dynamometer (Jamar®) and knee extension strength (KES) was assessed using the one-repetition maximum test (1-RM). Lower extremity (LE) functional performance was assessed using the Short Physical Performance Battery (SPPB) and body composition was measured using biometrical impedance analysis (Biodynamics Model 310). Results: There was a significant difference in muscle strength between groups. The group with MCI had lower PGS

Objective(s) To investigate the prevalence of microsatellite instability (MSI) in endometrial polyps and to evaluate whether there are clinical and histopathological parameters associated with this kind of instability. Study design Between September 2008 and April 2009, endometrial polyps were collected from 109 patients. MSI was evaluated using the NCI recommended markers BAT25, BAT26, D2S123, D5S346 and D17S250. Histopathological analysis was performed, and clinical information was obtained from patients' records. Result(s) MSI low was detected in 6.4% of the validated samples (7/109). Of the seven MSI that were detected, six were positive for instability at D17S250 and one at D5S346. There were no significant differences between polyps with or without MSI with regard to age, BMI, menarche, parity, miscarriage or menopause; however, MSI was more frequent in polyps with simple hyperplasia without atypia (3/20; 15%). Furthermore, patients with multiple polyps had a marginally but statistically insignificant increase in the frequency of MSI (p < 0.07). Conclusion(s) This is the first prospective study of MSI in endometrial polyps using hysteroscopically obtained samples. In a population of 109 patients, MSI was infrequent in endometrial polyps. Although MSI appears to be more frequent in multiple polyps and polyps with simple hyperplasia without atypia, this was not statistically significant.
