Question: To assess the therapeutic effects of flexible magnets on pain perception, intramuscular swelling, range of motion, and muscular strength in individuals with a muscle microinjury.', 'This experiment was a single-blind, placebo study using a repeated-measures design. Subjects performed an intense exercise protocol to induce a muscle microinjury. After pretreatment measurements were recorded, subjects were randomly assigned to an experimental (magnet), placebo (imitation magnet), or control (no magnet) group. Posttreatment measurements were repeated at 24, 48, and 72 hours.', 'Forty-five healthy subjects participated in the study.', 'Subjects were measured repeatedly for pain perception, upper arm girth, range of motion, and static force production. Four separate univariate analyses of variances were used to reveal statistically significant mean (+/-SD) differences between variables over time. Interaction effects were analyzed using Scheffe post hoc analysis.', 'Analysis of variance revealed no statistically significant (P > .05) mean differences between conditions for any dependent pretreatment and posttreatment measurements. No significant interaction effects were demonstrated between conditions and times.

Answer: Are flexible magnets effective in decreasing pain perception and recovery time after muscle microinjury?

Question: The vascular endothelial growth factor (VEGF) family and VEGF receptors (VEGFR) play an essential role in the angiogenesis of both pathologic and nonpathologic conditions. However, the prognostic significance of VEGF and VEGFR expression in ovarian carcinoma is unclear.', 'The tissue expression levels of VEGF-A, VEGF-C, VEGFR-2, and VEGFR-3 in 80 specimens of ovarian carcinoma were examined immnohistochemically. The results obtained were analyzed clinicopathologically.', 'VEGF-A, VEGF-C, VEGFR-2, and VEGFR-3 were expressed both in tumor cells and in adjacent endothelial cells of blood and lymph vessels. The tissue expressions of VEGF-C and VEGFR-2 were correlated significantly with tumor extension, including peritoneal metastases outside the pelvic cavity (P = 0.0010 and P = 0.0008, respectively), lymph node metastases (P = 0.0030 and P = 0.0018, respectively), and positive ascitic cytology (P = 0.025 and P = 0.0016, respectively). Conversely, there was no significant correlation between VEGF-A and VEGFR-3 expression and clinicopathologic features of ovarian carcinoma. Logistic regression analysis revealed that the expressions of VEGF-C and VEGFR-2 also were independent risk factors for peritoneal and lymph node metastases. Survival curves determined by the Kaplan-Meier method and in univariate analysis demonstrated that high expression levels of VEGF-C and VEGFR-2 were associated with the 5-year survival rate. In multivariate analysis, high expression levels of VEGF-C and VEGFR-2 emerged as independent indicators for disease-specific survival.

Answer: Are vascular endothelial growth factor C and vascular endothelial growth factor receptor 2 related closely to the prognosis of patients with ovarian carcinoma?

Question: Evidence-based fall prevention programs primarily attract older women, who are increasingly burdened by fall-related injuries. However, little is known about the relationship between older female participants' baseline health status and self-reported falls over the course of fall prevention interventions. Using data from A Matter of Balance/Volunteer Lay Leader Model (AMOB/VLL) workshops, this study examines female participants' sociodemographics and health indicators associated with self-reported falls at baseline and postintervention.", 'Data were analyzed from 837 older women (M = 76.2 years) collected during the statewide AMOB/VLL dissemination in Texas. Longitudinal Poisson regression models, using the generalized estimating equation method, were used to investigate the associations of personal characteristics and health indicators with and reductions in the number of self-reported falls from baseline to postintervention.', 'Approximately 21% of participants reported falling at baseline, and the number of reported falls significantly decreased from baseline to postintervention ( = -0.443). At baseline, more unhealthy physical days ( = 0.022), more unhealthy mental days ( = 0.018), and lower Falls Efficacy Scale scores ( = -0.052) were significantly associated with more falls reported at baseline. More falls at baseline was also associated with worse program attendance ( = -0.069). Greater improvements in Falls Efficacy Scale Scores ( = -0.069) and decreases in unhealthy physical health days ( = 0.026) over the course of the intervention were significantly associated with greater reductions in reported falls at postintervention, respectively.

Answer:
Does health indicators associated with fall among middle-aged and older women enrolled in an evidence-based program?
