OBJETIVO: O Harris Hip Score é instrumento de avaliação específica, desenvolvido originalmente para avaliar os resultados da artroplastia total de quadril. O objetivo deste estudo foi traduzir e adaptar culturalmente este instrumento para a língua portuguesa. MÉTODO: O método de tradução e adaptação cultural do Harris Hip Score envolveu quatro etapas: 1 - tradução inicial; 2 - retrotradução; 3 - apreciação das versões com elaboração da versão de consenso; 4 - pré-teste comentado com elaboração da versão final. RESULTADOS: A versão de consenso foi aplicada em 30 pacientes com afecção do quadril, sendo verificadas dificuldades no entendimento de algumas expressões, as quais foram substituídas por termos de mais fácil entendimento. Na reaplicação do questionário com a nova versão houve entendimento por 100% dos pacientes no que diz respeito ao sentido semântico, idiomático e contextual. CONCLUSÃO: A versão brasileira do Harris Hip Score permitiu a disponibilização de mais este instrumento para avaliação da qualidade de vida de pacientes com afecções do quadril. Há necessidade de um estudo de avaliação da confiabilidade e validade da versão adaptada culturalmente, a qual já está em desenvolvimento.

Our results suggest that regular supervised physical exercises with free weights and elastic bands can promote greater improvements in lean body mass than unsupervised exercises in postmenopausal women.

OBJECTIVE:To compare the renal outcome in patients submitted to two different regimens of glycemic control, using the RIFLE criteria to define acute kidney injury.INTRODUCTION:The impact of intensive insulin therapy on renal function outcome is controversial. The lack of a criterion for AKI definition may play a role on that.METHODS:Included as the subjects were 228 randomly selected, critically ill patients engaged in intensive insulin therapy or in a carbohydrate-restrictive strategy. Renal outcome was evaluated through the comparison of the last RIFLE score obtained during the ICU stay and the RIFLE score at admission; the outcome was classified as favorable, stable or unfavorable.RESULTS:The two groups were comparable regarding demographic data. AKI developed in 52% of the patients and was associated with a higher mortality (39.4%) compared with those who did not have AKI (8.2%) (p<0.001). Renal function outcome was comparable between the two groups (p = 0.37). We observed a significant correlation between blood glucose levels and the incidence of acute kidney injury (p = 0.007). In the multivariate logistic regression analysis, only APACHE III scores higher than 60 were identified as an independent risk factor for unfavorable renal outcome. APACHE III scores>60, acute kidney injury and hypoglycemia were risk factors for mortality.CONCLUSION:Intensive insulin therapy and a carbohydrate-restrictive strategy were comparable regarding the incidence of acute kidney injury evaluated using RIFLE criteria.

This study analysed the effect of low-intensity (LI) exercises with blood flow restriction (BFR) on bone metabolism compared with high-intensity (HI) exercises without BFR. The following databases were searched using the keywords therapeutic occlusion training OR BFR training OR vascular occlusion training OR KAATSU training OR ischaemia training AND osteogenesis OR bone biomarkers OR bone metabolic marker OR bone mass OR bone turnover OR osteoporosis OR osteopenia: PubMed, Web of Science, SPORTDiscus, CINAHL, Science Direct, Cochrane and Google Scholar. Two researchers, independently and blindly, selected the studies based on established inclusion and exclusion criteria. Electronic and manual searches located 170 articles published in English; after screening, only four studies showed that BFR training increases the expression of bone formation markers (e.g. bone-specific alkaline phosphatase) and decreases bone resorption markers (e.g. the amino-terminal telopeptides of type I collagen) after both aerobic and anaerobic exercise across several populations. The results of this study show that few studies have confirmed the positive effect of exercise with BFR on bone metabolism, formation and resorption. Furthermore, no methodological standardization of the samples, exercise type, intervention frequency or duration was observed.

Introduction: Improving strength levels is important to women with osteoporosis. Resistance and aerobic exercise are effective means of reaching this goal; however, the use of low-load exercises with blood flow restriction is an alternative to traditional methods of exercise to achieve the same strength gains in this population. Objective: To analyze the chronic effects of aerobic and resistance training combined with blood flow restriction on the maximal dynamic strength (MDS) of women with osteoporosis. Methods: Twenty women (61.40±4.63 years of age, 61.82±12.54 kg, 1.51±0.05 m, 27.16±5.55 kg/m²) were randomly assigned to four groups: 1 -high-intensity resistance training (HI); 2 -low-intensity resistance training with blood flow restriction (LI-BFR); 3 -aerobic training with blood flow restriction (ABFR); and 4 -control group (CG). Unilateral knee extension MDS was assessed using the one-repetition maximum (1RM) strength test before and after the 6 th and 12 th weeks of intervention. The data were analyzed using repeated measures analysis of variance (ANOVA) with a Bonferroni post-hoc test performed using SPSS (version 21.0), considering a significance level of P<0.05 for all tests. Results: Baseline comparisons showed that HI and CG had lower strength levels than LI-BFR and ABFR groups (P<0.05). The ABFR group exhibited a significant increase in MDS between the 1 st and the 6 th week (9%, P=0.001) and between the 1 st and the 12 th week (21.6%, P=0.008). The LI-BFR group exhibited increased MDS between the 1 st and the 6 th week (10.1%, P=0.001), between the 1 st and the 12 th week (24.2%, P=0.003) and between the 6 th and 12 th week (12.8%, P=0.030). The HI group exhibited a significant difference between the 1 st and the 6 th week (38.7%, P<0.001), between the 1 st and the 12 th week (62%, P<0.001) and between the 6 th and 12 th weeks (17.4%, P=0.020), whereas the CG had no significant differences between the timepoints (P>0.05). Conclusions: ABFR and LI-BFR effectively increased the MDS of women with osteoporosis.

Introduction The preservation of bone mass in elderly women is associated with better levels of practice of systematic physical exercises. Aerobic training combined with blood flow restriction seems to be a new alternative that determines this process, but knowledge gaps are still observed when referring to exercise associated with blood flow restriction (BFR) and adaptations on bone variables. Objective To analyze the chronic effects of aerobic training with and without BFR on bone mineral density and bone biomarker osteocalcin concentrations in older women. Methods Thirty women were randomized into the following groups: walking on a treadmill at low intensity with BFR; moderate treadmill walking with no BFR; only BFR (no exercise) for 20 minutes, twice a week, for 24 weeks. Bone mineral density was measured before and 24 weeks after intervention. Blood serum osteocalcin concentrations were measured before, 12 and 24 weeks after intervention. Results There were no differences between groups in bone mineral density (femoral neck, p = 0.31; total femur, p = 0.17; lumbar spin, p = 0.06) and osteocalcine (W(2) = 0.27; p = 0.87) ouctomes after 24 weeks of intervention. Conclusion There was no difference between walking training, blood flow restriction only, or walking+blood flow restriction on bone mineral density and osteocalcin concentrations after 24-weeks of intervention in older women with osteopenia/osteoporosis.

Verification of the auscultatory pulse in total blood flow restriction (BFR) has been a limiting factor in studies due to the way in which it is evaluated and prescribed, as hemodynamic measurements can be directly affected by gravity. The aim of the present study was to compare the auscultatory pulse in BFR between positions, genders, limbs and body segments in healthy young individuals. A total of 156 subjects participated in the study, 76 of whom were male and 80 of whom were female (23.9±3.7 years, 66.5±11.5 kg, 1.67±0.07 m). After filling in registration data, anthropometry was evaluated, and BFR pressure was determined. BFR was evaluated in a randomized manner in both limbs (upper and lower) and in both segments (right and left) in the following positions: a) lying in the supine position; B) sitting with knees and trunk at 90°; and c) standing in the anatomical position. Significant differences were observed between the lying, sitting and standing positions (p<0.05), between genders (p<0.05), between limbs (p<0.05) and between the right and left segments in the lower limb in both genders [males (p=0.014) and females (p=0.009)] in the lying position. However, no significant differences were observed between the right and left segments in the upper limbs (p>0.05). The BFR point appears to differ between positions, genders, lower limbs and segments. Therefore, it is recommended that health professionals should check the BFR point in the position relating to the exercise that will be performed, taking into account gender, lower limbs and body segments.
