RESUMEN

OBJECTIVE: To assess the association of residual diuresis with sarcopenia in patients with Chronic Kidney Disease (CKD) on hemodialysis. METHODS: Through a cross-sectional study, patients on hemodialysis were subjected to a Dual Energy Radiologic Absorption (DEXA) exam to record muscle mass. Based on the volume of urine collected in 24 hours, patients were classified as anuric (diuresis ≤ 100 mL/day) or non-anuric (diuresis > 100 mL/day). Functional performance was evaluated by Short Physical Performance Battery (SPPB) and muscle strength by handgrip strength and 5-repetition sit-to-stand test. The association between the absence of residual urine and the presence of sarcopenia, low SPPB, and low muscle strength was analyzed using a binary logistic regression model. RESULTS: Ninety-two patients, with a mean age of 54.4 years (95% CI 51.3 - 57.4) and with a mean diuresis volume of 476.3 mL/day (95% CI 320.4 - 632.2) were evaluated (48 anuric and 44 non-anuric). Anuric patients had a 2.77 (95% CI 1.14 - 6.73) times greater probability of sarcopenia and had a 3.55 (1.14 - 11.0) times greater probability of low SPPB, regardless of gender, age, and time on dialysis. Gender was the other associated variable for the presence of sarcopenia, with males having a 3.30 (95% CI 1.34 - 8.13) times higher risk. There were no associations with muscle strength. CONCLUSION: The absence of residual diuresis in patients on hemodialysis is associated with a higher risk of sarcopenia and low functional performance.

RESUMEN

BACKGROUND: Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects the premature lung, and to reduce its incidence has been used non-invasive ventilatory support, such as continuous positive airway (CPAP) and high-flow nasal cannula (HFNC). Thus, the objective of this review was to assess whether the use of high flow nasal cannula (HFNC) compared to continuous positive airway pressure (CPAP) decreases the risk of bronchopulmonary dysplasia (BPD) in premature newborns. METHODS: The protocol was registered (Prospero: CRD42019136631) and the search was conducted in the MEDLINE, PEDro, Cochrane Library, CINAHL, Embase, and LILACS databases, and in the clinical trials registries, until July 2020. We included randomized clinical trials comparing HFNC versus CPAP use in premature infants born at less than 37 weeks of gestational age. The main outcome measures were the development of BPD, air leak syndrome, and nasal injury. The methodological quality of the included studies was assessed using the Cochrane risk of bias tool and the GRADE system was used to summarize the evidence recommendations. Meta-analyses were performed using software R. RESULTS: No difference was found between HFNC or CPAP for the risk of BPD (RR: 1.10; 95% CI: 0.90-1.34), air leak syndrome (RR: 1.06; 95% CI: 0.52-2.14), and nasal trauma (RR: 2.00; 95% CI: 0.64-6.25), with a very low level of evidence. CONCLUSION(S): The HFNC showed similar results when compared to CPAP in relation to the risk of BPD, air leak syndrome, and nasal injury. In the literature, no randomized clinical trial has been found with BPD as the primary outcome to support possible outcomes.

RESUMEN

The purpose of this study was to investigate the effects of an exercise program based on the Pilates Matwork method on sedentary volunteers who self-reported changes in their sleep quality and quality of life. This was a prospective clinical study, in which the variables (level of sleepiness and quality of life) were compared before and after applying a protocol of 12 weeks of an exercise program (2 sessions per week). The level of sleepiness showed significant improvement between before and after the intervention (p: 0.04). Quality of life improved based on all of the emotional components and the physical components (p < 0.05) with the exception of the physical domain (p: 0.09). The results of this study indicate that the sedentary population who participated in this 12 week Pilates program experienced improvements in sleep quality and quality of life.

RESUMEN

INTRODUCTION: Chronic kidney disease consists in the slow, progressive and irreversible loss in renal function and it is considered a social and economic problem worldwide, since it is linked to numerous diseases, as well as to higher public health spending. It is known that dialysis patients undergo a long period of restricted physical activity reflects in dysfunctions in various organical systems and in the quality of their lives. OBJECTIVE: To verify the results of physical therapy intervention in patients on hemodialysis, for respiratory muscle function, grip strength and quality of life. METHODOLOGY: Experimental, nonrandomized, quantitative and qualitative of a sample of 13 patients, 43.69 ± 9.28 years, on hemodialysis in the hospital Santa Casa de Diamantina/MG, selected by convenience. All patients were evaluated for maximal respiratory pressures (PI(max) e PE(max) ) and peak expiratory flow (PFE), before and after physiotherapy, which consisted of 3 sessions per week for a period of 2 months weeks: exercises for upper limbs, with technique PNF and breathing diaphragmatic; strengthening exercises for lower limbs and use of exerciser ball. Statistical analysis was performed using the student-t test and significance value at p < 0.05. RESULTS: Respective means for the variables before and after intervention were: PImáx (97.69 ± 28.3 cmH2O e 98.46 ± 23.39 cmH2O) p = 0.93; PEmáx (83.07 ± 31.19 cmH(2)O e 88.46 ± 14.0 cmH(2)O) p = 0.46 e PF (375.38 ± 75.23 L/min e 416.15 ± 57.37 L/min) p = 0.02. The dynamometer average pre intervention was: 57.23 ± 17.39 kgf and post intervention: 56.61 ± 16.09 kgf. In the SF-36, which evaluates the quality of life, improvement was observed in the eight domains, except the item 'vitality'. Of all the variables measured only the PFE was statistically significant. CONCLUSION: The proposed physical therapy protocol did not promote significant improvements in those variables, the statistical point, explaining in part the small sample size, time of protocol and proposed interventions.
