Background This study aimed to investigate the relationship between radiological severity, as assessed by the individual grades and grouped grades (grades “0 and 1” and “2 to 4”) of the Kellgren-Lawrence scale (K&Ls), and depression symptoms, cognitive loss, risk of falls, and quality of life in relation to knee osteoarthritis, as assessed by other instruments. Methods Data recorded between 2013 and 2014 in Amparo (São Paulo, Brazil) were retrieved for analysis. A total of 181 elderly patients who had knee osteoarthritis and underwent a radiologic exam were evaluated for depressive symptoms, cognitive loss, quality of life, and risk of falls by the Geriatric Depression Scale (GDS), Mini-Mental State Examination (MMSE), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), timed up and go test (TUG), and Berg balance scale (BBS). For statistical analyses, Fisher’s exact test, Mann-Whitney test, Kruskal-Wallis test, and Spearman’s coefficient analysis were used. Results There was no significant relationship between the scores of the instruments investigated and the individual K&Ls grades. However, when the K&Ls scores were assessed by groups, grades “2 to 4” were associated with the worst WOMAC score and the highest frequency and risk of falls according to the BBS but not according to TUG. For the GDS and MMSE, no significant relationships with the K&Ls grades were found. In addition, the K&Ls grade was correlated with the WOMAC score, regardless of the domain. Conclusion The radiological scores of the Kellgren-Lawrence (K&L) scale were associated with poorer WOMAC and BBS scores only when the K&Ls scores were evaluated in groups, and the WOMAC score was associated with an increase in the radiological grade.

The menstrual cycle has been pointed as a possible factor of interference in the physical training, but the relation between its different phases and the physical performance has been recent target of investigation. Thus, the aim of this study was to verify the physical performance in the motor capacities of aerobic resistance and muscular strength during the menstrual cycle phases. During two complete menstrual cycles, 12 healthy, active and oral contraceptive women underwent a training protocol. During training were evaluated for physical performance in each phase of each cycle through the tests: Yo Yo Test 1 and one repetition maximum test (1RM) for exercises in the leg extension, bench press, leg curl and rower machine. The results point to a reduction of the resistance performance in the follicular phase for both menstrual cycles evaluated. The behavior of muscle strength was significantly higher in the second cycle for the bench press and leg curl exercises. We concluded that the performance on resistance capacity in active women, when evaluated in two menstrual cycles, is lower in the follicular phase, while the muscular strength performance was not influenced by the menstrual cycle phases.Keywords: physical fitness, exercise, women.
Background:The cognitive changes in Mild Cognitive Impairment (MCI) can be associated to the neurodegeneration of Alzheimert's pathology, such as white matter atrophy. Increasing evidence demonstrates that physical activity is an important modifiable factor not only for cardiovascular fitness, but also for brain health. Therefore, the aim of this study was to analyze possible effects of 6 months of multicomponent exercise (MEP) on structural connectivity of MCI in the AD continuum.Method: 19 MCI subjects were diagnosed using the core criteria of the NIA/AA for MCI and altered CSF amyloid. All of them underwent MRI on a 3.0T Philips Achieva scanner. They were divided into MEP group (3x/week for 6 months) and control group (CG,
