Predictors of extubation failure in neurocritical patients: A systematic review.

OBJECTIVE: The objective of this study was to identify predictors of extubation failure in neurocritical patients. METHODS: This was systematic review performed through a bibliographic search of the databases PubMed/Medline, Lilacs, SciELO, and Web of Science, from February 2020 to October 2021. Cohort studies that investigated the predictors of extubation failure were included, defined as the need for reintubation within 48 h after extubation, in adult neurocritical patients. The risk-of-bias assessment was performed using the Newcastle-Ottawa Scale, for cohort studies. RESULTS: Eight studies, totaling 18 487 participants, were included. A total of 15 predictors for extubation failure in neurocritical patients have been identified. Of these, four were the most frequent: low score on the Glasgow Coma Scale (motor score ≤5, 8T-10T), female gender, time on mechanical ventilation (≥7 days, ≥ 10 days), and moderate or large secretion volume. CONCLUSIONS: In addition to the conventional parameters of weaning and extubation, other factors, such as a low score on the Glasgow Coma Scale, female gender, mechanical ventilation time, and moderate or large secretion volume, must be taken into account to prevent extubation failure in neurocritical patients in clinical practice.

The impact Of high-intensity interval training On functioning And health-related quality Of life In post-stroke patients: A systematic review With meta-analysis.

OBJECTIVE: To examine the effects of high-intensity interval training on the functioning and health-related quality of life of post-stroke patients. METHODS: We searched the following electronic databases: MEDLINE/Pubmed, Cochrane Central Register of Controlled Trials, PEDro database, and Scielo up to January 2022 for randomized controlled trials that investigated the effects of high-intensity interval training in post-stroke patients. Two reviewers selected the studies independently. Study quality was evaluated using the PEDro scale. The mean difference (MD), standard mean difference (SMD), and 95% confidence intervals (CIs) were calculated. RESULTS: Nine studies met the study criteria (375 patients). The age of the participants ranged from 55.8 to 72.1 years. The studies included patients within 2 weeks of stroke onset to patients longer than 1 month of stroke. High-intensity interval training resulted in improvement in cardiorespiratory fitness (peak oxygen uptake) MD (3.8 mL/kg/min, 95% CI: 2.62, 5.01, n = 91), balance MD 5.7 (95% CI: 3.50, 7.91; N = 64), and gait speed SMD (0.2 m/s; 95% CI: 0.05, 0.27; N = 100) compared with continuous aerobic training. The health-related quality of life did not differ between the groups. Compared to usual care, high-intensity interval training improved the cardiorespiratory fitness SMD (0.5 95% CI: 0.14, 0.81, n = 239). No serious adverse events were observed. CONCLUSIONS: The findings of this systematic review show that high-intensity interval training was more efficient than continuous aerobic training to gain cardiorespiratory fitness, balance and gait speed in post-stroke patients. In addition, compared to usual care, high-intensity interval training improved cardiorespiratory fitness.

Effect of exercise on epicardial adipose tissue in adults: a systematic review and meta-analyses.

According to previous epidemiological studies, we can reduce the thickness of epicardial fat and improve cardiovascular risk factors through exercise, and the changes may depend on the form of exercise. We systemically reviewed published studies that evaluated exercise intervention on epicardial adipose tissue (EAT) levels. We included randomized controlled trials (RCTs) comparing one exercise with another exercise or diet for the treatment to reduce EAT. We used fixed effects models for meta-analyses; effects of exercise on outcomes were described as mean differences (MD) or standardized difference of means (SMD) was used, their 95% confidence intervals (CI). Five RCTs were included (n = 299), 156 in exercise group and 143 in the control. In comparison to the control group, exercise significantly reduced EAT (SMD - 0.57, 95%CI - 0.97 to - 0.18) and waist circumference (MD - 2.95 cm, 95%CI - 4.93 to - 0.97). Exercise did not have an effect on BMI (MD - 0.23 kg/m2, 95%CI - 0.73 to 0.27), weight (MD - 0.06 kg, 95%CI - 1.46 to 1.34), or HDL (SMD 0.26, 95%CI - 0.06 to 0.57).VO2 was significantly increased by exercise (SMD 1.58, 95%CI 1.17 to 1.99). Risk of bias was high for 3 studies, and GRADE quality of evidence was very low to moderate. Exercise reduced epicardial adipose tissue and waist circumference, and did not have effect on weight, BMI, or HDL. Newer trials with better design and methods are necessary to improve the quality of the evidence. PROSPERO registration number (CRD42018096581).

Endomyocardial fibrosis: past, present, and future.

Endomyocardial fibrosis (EMF) is a neglected idiopathic disorder, predominant in tropical and subtropical regions of the developing world. It is characterized by fibrotic thickening of the endocardium and myocardium of one or both ventricles. EMF was an important cause of heart failure which accounted for up to 20% of the cases in endemic areas of Africa (rural community in Mozambique), but during the last few years, incidents of the disease have decreased considerably. Although its pathogenesis and etiology are not fully understood, its pathology resembles conditions such as eosinophilic cardiomyopathy and hypereosinophilic syndrome. Extensive fibrosis of the ventricular endocardium causing architectural distortion, impaired filling, and valvular insufficiency defines the disease. Confined to peculiar and limited geographical areas, the etiology remains blurred and it carries a grim prognosis. Medical care currently remains very challenging as one-third to half of patients with an advanced disease die within 2 years. Surgery in the correct setting can increase survival and especially in patients with advanced heart failure.

The Effects of Functional Training, Bicycle Exercise, and Exergaming on Walking Capacity of Elderly Patients With Parkinson Disease: A Pilot Randomized Controlled Single-blinded Trial.

OBJECTIVES: To compare the effects of functional training, bicycle exercise, and exergaming on walking capacity of elderly with Parkinson disease (PD). DESIGN: A pilot randomized, controlled, single-blinded trial. SETTING: A state reference health care center for elderly, a public reference outpatient clinic for the elderly. PARTICIPANTS: Elderly individuals (≥60 years of age; N=62) with idiopathic PD (stage 2 to 3 of modified Hoehn and Yahr staging scale) according to the London Brain Bank. INTERVENTION: The participants were randomly assigned to three groups. Group 1 (G1) participated in functional training (n=22); group 2 (G2) performed bicycle exercise (n=20), and group 3 (G3) trained with Kinect Adventures (Microsoft, Redmond, WA) exergames (n=20). MAIN OUTCOME MEASURES: The primary outcome measure was the 6-minute walk test (6MWT); secondary outcome measures were the 10-m walk test (10MWT), sitting-rising test (SRT), body mass index, Parkinson Disease Questionnaire-39, World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), and 15-item Geriatric Depression Scale. RESULTS: All groups showed significant improvements in 6MWT (G1 P=.008; G2 P=.001; G3 P=.005), SRT (G1 P<.001; G2 P=.001; G3 P=.003), and WHODAS 2.0 (G1 P=.018; G2 P=.019; G3 P=.041). Only G3 improved gait speed in 10MWT (P=.11). G1 (P=.014) and G3 (P=.004) improved quality of life. No difference was found between groups. CONCLUSIONS: Eight weeks of exergaming can improve the walking capacity of elderly patients with PD. Exergame training had similar outcomes compared with functional training and bicycle exercise. The three physical exercise modalities presented significant improvements on walking capacity, ability to stand up and sit, and functionality of the participants.

Virtual rehabilitation via Nintendo Wii® and conventional physical therapy effectively treat post-stroke hemiparetic patients.

BACKGROUND: The Nintendo® Wii is a simple and affordable virtual therapy alternative. It may be used at home, and it is a motivating recreational activity that provides continuous feedback. However, studies comparing the use of the Nintendo® Wii to conventional physical therapy are needed. OBJECTIVE: To compare the effect of a rehabilitation treatment using the Nintendo® Wii (NW) with conventional physical therapy (CPT) to improve the sensorimotor function and quality of life for post-stroke hemiparetic patients. METHODS: The present study applied a randomized, blind, and controlled clinical trial. In total, 30 patients with post-stroke hemiparesis were evaluated. A total of 15 patients were randomly assigned to each group. The SF-36 quality of life and Fugl-Meyer scales were used to evaluate the patients. RESULTS: After treatment, the only variable that differed between the groups was the physical functioning domain of the SF-36 in the group that received conventional physical therapy. A significant difference was observed between both groups before and after treatment in terms of the following Fugl-Meyer scale items: passive movement and pain, motor function of the upper limbs (ULs), and balance. The CPT group also showed a significant difference with regard to their UL and lower limb (LL) coordination. The SF-36 scale analysis revealed a significant difference within both groups with regard to the following domains: physical functioning, role limitation due to physical aspects, vitality, and role limitation due to emotional aspects. The NW group also exhibited a significant difference in the mental health domain. The results indicate that both approaches improved the patients' performance in a similar manner. CONCLUSION: Virtual rehabilitation using the Nintendo Wii® and CPT both effectively treat post-stroke hemiparetic patients by improving passive movement and pain scores, motor function of the upper limb, balance, physical functioning, vitality, and the physical and emotional aspects of role functioning.

Combined exercise on fatigue, quality of life and physical functioning in people under chemotherapy with oxaliplatin: Systematic review and meta-analysis.

OBJECTIVE: To investigate the effects of combined exercise on fatigue, anxiety, depression, quality of life and physical functioning in gastroinstestinal neoplasm in people under chemotherapy with oxaliplatin treatment. METHODS: We searched pubmed/MEDLINE, Cochrane Central Register of Controlled Trials, PEDro data base, and SciELO (until Nov 2023) for randomized controlled trials that investigated the effects of combined exercise in gastroinstestinal neoplasm people under chemotherapy with oxaliplatin treatment. Two comparisons were made: combined exercise versus usual care, combined aerobic and versus usual care (follow up). The main outcomes were muscle strength, aerobic capacity, fatigue, anxiety, depression and quality of life. Mean differences (MD) with 95% confidence interval (CI) were calculated. RESULTS: Seven randomized controlled trials met the eligibility criteria, which included 464 people. Compared to usual care, combined aerobic and resistance resulted in decrease of general fatigue (-2.82; IC: 4.92 to -0.69, N = 48), physical fatigue (-5.08; IC: 8.41 to -1.74, N = 48) and improvement of domain physical functioning of quality of life (9.40; IC: 2.74 to 16.06, N = 48). Compared to usual care, combined aerobic and resistance - Follow up resulted in decrease of general fatigue (-2.32; IC: 4.41 to - 0.28, N = 48), physical fatigue (-0.92; IC: 3.31 to -1.47, N = 48) and improvement ofdomain physical functioning of (9.83; IC: 0.66 to 19.01, N = 48). CONCLUSIONS: Our results demonstrate that combined exercises improves fatigue (general; physical), domain physical functioning of quality of life in gastrointestinal neoplasm people under chemotherapy treatment when compared to usual care.

Development, reliability, and validity of the mobility assessment scale in hospitalized patients (HMob).

BACKGROUND: Existing mobility scales for hospitalized patients do not include assessment of tasks for the right and left side, ability to transfer from sitting to lying and from standing to sitting, ability to climbing steps and pick up an object from the floor in the same instrument. OBJECTIVE: Evaluate the reliability and validity of the hospital mobility assessment scale (HMob) according to the Consensus-based standards for the selection of health measurement instruments (COSMIN). METHODS: Study conducted in three inpatient units (cardiology, neurology, and gastrohepatology) and one adult intensive care unit in a hospital. Patients of both sexes were included; age >18 years; collaborative and who obeyed commands, with different medical diagnoses and clinical release to leave their bed (provided by the doctor). Special populations such as those with burns and orthopedics were excluded. RESULTS: The sample consisted of 130 patients; 20 from the pilot study and 110 to assess the clinimetric properties of the HMob. Cronbach alpha coefficient was 0.949. Relative intra- (A1-A2) and inter-rater (A1-B; A2-B) reliability was excellent (A1-A2: ICC = 0.982, p-value < 0.0001; A1-B: ICC = 0.993, p-value < 0.0001; A2-B: ICC = 0.986, p-value < 0.0001.) The convergent criterion validity of HMob in relation to the ICU Functional Status Score was 0.967 (p-value < 0.0001) and for Functional Independence measure (MIF) was 0.926 (p-value < 0.0001). CONCLUSION: The HMob scale showed excellent internal consistency, intra- and inter-rater reliability, and concurrent validity in the motor domain, which suggests that it can be used in daily practice to measure mobility in hospitalized patients.

Effect of Mobilization with Movement on Pain, Disability, and Range of Motion in Patients with Shoulder Pain and Movement Impairment: A Systematic Review and Meta-Analysis.

BACKGROUND: Shoulder pain is a disabling musculoskeletal disorder worldwide. Thus, it is important to identify interventions able to improve pain and disability. OBJECTIVE: To investigate the effects of mobilization with movement (MWM) on pain, disability, and range of motion in patients with shoulder pain and movement impairment. METHODS: A systematic search of different databases was performed. The systematic review protocol has been registered in PROSPERO (CRD42023404128). A random-effects model for meta-analysis was used to determine the mean difference (MD), standardized mean differences (SMD), and 95% confidence interval for the outcome of interest. RESULTS: Twenty-six studies were included. Of these, eighteen were included in the meta-analysis. MWM improved pain during movement with a moderate effect SMD of (-0.6; 95% confidence interval, -1.1 to -0.1, I2 = 0%; N = 66;) and shoulder abduction MD of (12.7°; 1.3 to 24.0; I2 = 73%; N = 90) compared to sham MWM in the short term (0-6 weeks). Combined MWM and conventional rehabilitation improved pain at rest, with a MD of (-1.2; -2.2 to -0.2; I2 = 61%; N = 100), and disability SMD of (-1.3; confidence interval -2.2 to -0.4; I2 = 87%; N = 185) compared to conventional rehabilitation alone in the short term. Combined MWM and conventional rehabilitation also resulted in improvement in shoulder abduction and external rotation. Compared to Maitland, MWM resulted in improvement in the shoulder abduction MD (20.4°; confidence interval 4.3 to 36.5; I2 = 89%; N = 130) in the short term. There is no information regarding long-term effects. CONCLUSION: Evidence suggests that MWM may reduce shoulder pain and restore shoulder range of motion and function. Our findings are promising, but the evidence is not strong enough to recommend it pragmatically.

Addition of respiratory exercises to conventional rehabilitation for children and adolescents with cerebral palsy: a systematic review and meta-analysis.

BACKGROUND: Respiratory dysfunctions are an important cause of morbidity and death in cerebral palsy (CP) populations. Respiratory exercises in addition to conventional rehabilitation have been suggested to improve respiratory status in CP patients. The objective of this systematic review and meta-analysis was to verify the effects of the addition of respiratory exercises to conventional rehabilitation on pulmonary function, functional capacity, respiratory muscle strength, gross motor function and quality of life in children and adolescents with CP. METHODS: We searched for randomized controlled clinical trials in PubMed/Medline, Lilacs, SciELO, EMBASE and Physiotheraphy Evidence (PEDro) from their inception until July 2022 without language restrictions. Studies that included respiratory exercises (breathing exercise program; feedback respiratory training; incentive spirometer exercise; inspiratory muscle training; and combination of respiratory exercises + incentive spirometer exercise) in combination with conventional rehabilitation for children and adolescents with CP were evaluated by two independent reviewers. The mean difference (MD) and 95% confidence interval (CI) were estimated by random effect models. RESULTS: Ten studies met the eligibility criteria, including 324 children aged from 6 to 16 years. The meta-analysis showed an improvement in inspiratory muscle strength of 22.96 cmH2O (18.63-27.27, n = 55) and pulmonary function of 0.60 (0.38-0.82, n = 98) for forced vital capacity (L); 0.22 (0.06-0.39, n = 98) for forced expiratory volume at 1 second (L); and 0.50 (0.05-0.04, n = 98) for peak expiratory flow (L/min). Functional skills in daily living activities improved in the intervention group. Caregivers' assistance of daily living activities, functional capacity, gross motor function and expiratory muscle strength showed a nonsignificant improvement. Social well-being and acceptance and functioning domains improved in only one study. CONCLUSIONS: Emerging data show significant enhancements in inspiratory muscle strength and pulmonary function in CP patients after respiratory training in addition to conventional rehabilitation. There is no consensus on the frequency, type or intensity of respiratory exercises for children with and adolescents with CP.

A systematic review on physical function, activities of daily living and health-related quality of life in COVID-19 survivors.

OBJECTIVE: To analyze the published studies that investigated the physical function, activities of daily living and health-related quality of life in COVID-19 survivors. DESIGN: Systematic review. METHODS: We searched MEDLINE/PubMed, Scopus, SciELO, and Cochrane Library for studies that evaluated the physical function, activities of daily living and health-related quality of life after COVID-19 from the earliest date available to July 2021. Two independent reviewers screened and selected the studies. The Newcastle Ottawa Scale was used to evaluate methodological quality. RESULTS: We included 35 studies in this systematic review. Of the 35 studies included, 28 were cohort, and 7 cross-sectional studies The studies demonstrated that COVID-19 survivors had reduced levels of physical function, activities of daily living, and health-related quality of life. Furthermore, incomplete recovery of physical function, and performance in activities of daily living were observed 1 to 6 months post-infection. DISCUSSION: Physical disability and reduction in health-related quality of life is a common condition in post-COVID-19 and impairments may persist up to 1 to 6 months. Researchers and clinicians can use these findings to understand the potential disabilities and rehabilitation needs of people recovering from the COVID-19.

Efficacy and safety of very early mobilization after thrombolysis in acute ischemic stroke: a randomized clinical trial.

BACKGROUND: Stroke has a deleterious impact on human health due to its high incidence, degree of disabling sequelae and mortality, constituting one of the main causes of death and disability worldwide. OBJECTIVES: This study aimed to assess the efficacy and safety of very early mobilization (VEMG) after thrombolysis in functional recovery in patients with acute ischemic stroke. METHODS: The present study was an open, prospective, randomized study, with no blinded outcome, carried out in the stroke unit of a tertiary referral hospital located in Salvador-Bahia, Brazil. The primary outcome was the level of functional independence. Secondary outcomes were functional mobility, balance, complications within 7 days of hospitalization and 90 days after hospital discharge, and length of stay. OUTCOMES: A total of 104 patients with ischemic stroke who received thrombolytic treatment between August 2020 and July 2021 were prospectively recruited to the study. Of these, 51 patients received VEMG within 24 h of the ictus and another 53 patients receiving usual care (UCG) with mobilization 24 h after the ictus. When compared to the usual care, the VEMG group was not associated with a significant reduction in the risk of the primary outcome (relative risk [95% confidence intervals]: 0.74 [0.339-1.607]) or any of the secondary outcomes. CONCLUSION: In this study, the strategy of early mobilization after thrombolysis in ischemic stroke was safe, but without evidence of short-term benefit.

Performance-based tests in subjects with stroke: outcome scores, reliability and measurement errors.

OBJECTIVES: To assess the intra- and inter-rater reliabilities and measurement errors of seven widely applied performance-based tests for stroke subjects (comfortable/maximal gait speeds and both stair ascending/descending cadences, as well as the Timed 'Up and Go' test) and to verify whether the use of different types of outcome scores (one trial, the means of two and three trials, and the best and the worst values of the three trials) affected the score values, as well as their reliability and measurement errors. DESIGN: Intra- and inter-rater reliability study. SETTING: Research laboratory. SUBJECTS: Sixteen stroke subjects with a mean age of 52 ± 17.9 years. MAIN MEASURES: Seven performance-based tests, over two sessions, seven days apart, evaluated by two independent examiners. A third examiner recorded all data. One-way ANOVAs, intra-class correlation coefficients (ICCs) and percentages of the standard errors of measurement (SEM%) were used for analyses. RESULTS: For all tests, similar results were found for all types of outcome scores (0.01 ≤ F ≤ 0.56; 0.34 ≤ p ≤ 0.99). For instance, at the comfortable gait speed, the means (SD) values for the first trial, the means of two and three trials and the best and worst of three trials were, respectively, 1.04 (0.25), 1.04(0.24), 1.05 (0.24), 1.10 (0.26), 1.02 (0.24) seconds. Significant and adequate values of intra- (0.75 ≤ ICC ≤ 0.96; p ≤ 0.002) and inter-rater (0.75 ≤ ICC ≤ 0.97; p ≤ 0.001) reliabilities were found for all tests and outcome scores. Measurement errors were considered low (5.01 ≤ SEM% ≤14.78) and were also similar between all outcome scores. CONCLUSIONS: For the seven tests, only one trial was necessary to provide consistent and reliable results regarding the functional performances of stroke subjects.

Effects of water-based exercises on functioning of postmenopausal women: A systematic review with meta-analysis.

OBJECTIVE: The aim of the present study was to compare the efficacy of Water-Based Exercise (WBE) versus Land-Based Exercise (LBE) and of WBE versus Non-Exercise in postmenopausal women on muscle strength, agility, flexibility, bone mineral density and aerobic capacity. METHODS: We systematically searched in MEDLINE, PEDro, SciELO and the Cochrane Library RCT published until May 2022. Only randomized controlled trials were included. We analyzed the pooled results using weighted mean differences, standardized mean difference, and 95%CI were calculated. RESULTS: Twenty studies met the inclusion criteria; although, sixteen studies were included in the meta-analyses. The studies presented low methodological quality. WBE was more effective than NE for improving muscle strength of knee extension (3.34), knee flexion (2.51), arm curl (6.78 repetitions), VO2Max (4.12 ml/kg), and flexibility (6.38 cm) When comparing WBE with LBE, no significant statistical difference was found regarding muscular strength of lower limbs (1.00), muscular strength of upper limbs (0.47), flexibility (1.95 cm), aerobic capacity (0.82 ml/kg) and lumbar bone mineral density (0.04 g/cm2). CONCLUSIONS: WBE promotes significant benefits in muscle strength, aerobic capacity, and flexibility, when compared to no intervention. However, WBE was similar to the LBE for improving muscle strength, aerobic capacity, flexibility, agility, and bone mineral density - lumbar in postmenopausal women.

Effects of ventilator hyperinflation on pulmonary function and secretion clearance in adults receiving mechanical ventilation: A systematic review with meta-analysis.

INTRODUCTION: It is important to clarify the effect of ventilator hyperinflation(VHI) on pulmonary function and secretion clearance in adults receiving mechanical ventilation(MV). There is no published meta-analysis on the effects VHI on pulmonary function and secretion clearance in adults receiving MV. Objective Analyze the published randomized clinical trials(RCTs) that investigated the effects of VHI on pulmonary function and secretion clearance in adults receiving MV, comparing VHI with isolated aspiration, VHI with manual hyperinflation(MHI), VHI +vibrocompression(VB) versus VB and VHI+VB versus isolated aspiration. METHODS: The following databases PubMed, LILACS, EMBASE, SciELO, PEDro database and Cochrane Central Register of Controlled Trials (CENTRAL) were consulted up to December 2021. Secretion clearance, static and dynamic compliance of the respiratory system(Cstat and Cdyn), airway resistance(Raw) and oxygenation outcomes were evaluated. RESULTS: Thirteen studies met the study criteria, but only 12 studies were included on meta-analysis. There was no difference between VHI versus isolated aspiration for amount of secretions removed(0.41 SMD; 95% CI: -0.08 to 0.89; n=270), VHI versus MHI(0.51 grams; 95% CI: -0.08 to 1.11; n=256), VHI+VB versus VB(0.31 grams; 95% CI: -0.42 to 1.05; n=130) and VHI+VB versus isolated aspiration(0.54 grams; 95% CI: -0.06 to 1.14; n=132). There was difference for VHI versus isolated aspiration to Cstat (4.77 ml/cm H2O; 95% CI: 2.41 to 7.14; n= 136). CONCLUSION: Taking into account all studies included in meta-analysis, no evidences was found that VHI was effective in increasing the amount of secretions removed, Cdyn and oxygenation, but VHI seems to show a slight improvement in Cstat when compared to isolated aspiration. No evidence was found that VHI was effective in increasing the amount of secretions removed, Cdyn and oxygenation, but VHI seems to show a slight improvement in Cstat when compared to isolated aspiration.

Does adding hip strengthening exercises to manual therapy and segmental stabilization improve outcomes in patients with nonspecific low back pain? A randomized controlled trial.

BACKGROUND: The literature is unclear on the need for hip strengthening in persons with low back pain (LBP). OBJECTIVES: To investigate the effectiveness of hip strengthening exercises when added to manual therapy and lumbar segmental stabilization in patients with chronic nonspecific LBP. METHODS: Seventy patients with chronic nonspecific LBP were randomly assigned to either the manual therapy and lumbar segmental stabilization group or the manual therapy and lumbar segmental stabilization plus specific hip strengthening group. A 10 cm visual analogue scale and the Rolland-Morris Questionnaire were the primary clinical outcome measures at baseline, at the end of treatment (posttreatment), and 6- and 12-months posttreatment. Hip strength and kinematics were measured as secondary outcomes . RESULTS: While within-group improvements in pain, disability, and hip extensors strength occurred in both groups, there were no significant between-group differences at posttreatment or follow-ups. Mean difference in changes in pain level between groups at posttreatment and at 6- and 12-month follow-up were 0.5 points (95% confidence interval [CI]: -0.5, 1.5), 0.3 points (95% CI: -0.9, 1.5), and 0.0 points (95% CI: -1.1, 1.1), respectively. The mean differences in changes in disability were 0.8 points (95% CI: -1.3, 2.7), 0.0 points (95% CI: -2.4, 2.4), and 0.4 points (95% CI: -2.0, 2.8), respectively. Finally, we did not observe any between-group differences for any of the other outcomes at any timepoint. CONCLUSION: The addition of specific hip strengthening does not appear to result in improved clinical outcomes for patients with nonspecific LBP.

Prognostic power of conventional echocardiography in individuals without history of cardiovascular diseases: A systematic review and meta-analysis.

Echocardiographic abnormalities are associated with a higher incidence of adverse cardiovascular outcomes. This systematic review and meta-analysis aimed to evaluate whether echocardiographic abnormalities are predictors of cardiovascular events in individuals without previous cardiovascular diseases. The PubMed, Scopus, and SciELO databases were searched for longitudinal studies investigating the association between echocardiographic abnormalities and cardiovascular events among individuals without known cardiovascular diseases. Two independent reviewers analyzed data on the number of participants, age and sex, echocardiographic alterations, follow-up time, and cardiovascular outcomes. The meta-analysis estimated the risk ratio (RR) and 95% confidence interval (CI). Heterogeneity was assessed using I2 test. Twenty-two longitudinal studies met the eligibility criteria, comprising a total of 55,603 patients. Left ventricular hypertrophy (LVH) was associated with non-fatal cardiovascular events (RR 2.16; 95% CI 1.22-3.84), death from cardiovascular disease (RR 2.58; 95% CI 1.83- 3.64), and all-cause mortality (RR 2.02; 95% CI 1.34-3.04). Left ventricular diastolic dysfunction (LVDD) and left atrial dilation (LA) were associated with fatal and non-fatal cardiovascular events (RR 2.01; 95% CI 1.32-3.07) and (RR 1.78; 95% CI 1.16-2.73), respectively. Aortic root dilation was associated with non-fatal cardiovascular events (RR 1.25; 95% CI 1.09-1.43). In conclusion, LVH, LVDD, dilations of the LA, and of the aortic root were associated with an increased risk of adverse events in individuals without previous cardiovascular diseases. This study suggests that simple data obtained on conventional echocardiography can be an important predictor of cardiovascular outcomes in a low-risk population.

Rivaroxaban Versus Warfarin in Patients with Mechanical Heart Valves: Open-Label, Proof-of-Concept trial-The RIWA study.

BACKGROUND AND PURPOSE: To date, vitamin K antagonists are the only available oral anticoagulants in patients with mechanical heart valves. In this way, we developed a pilot trial with rivaroxaban. METHODS:  The RIWA study was a proof-of-concept, open-label, randomized clinical trial and was designed to assess the incidence of thromboembolic and bleeding events of the rivaroxaban-based strategy (15 mg twice daily) in comparison to dose-adjusted warfarin. Patients were randomly assigned in a 1:1 ratio and were followed prospectively for 90 days. RESULTS:  A total of 72 patients were enrolled in the present study. Of these, 44 patients were randomized: 23 patients were allocated to the rivaroxaban group and 21 to the warfarin group. After 90 days of follow-up, the primary outcome occurred in one patient (4.3%) in the rivaroxaban group and three patients (14.3%) in the warfarin group (risk ratio [RR] 0.27; 95% confidence interval [CI] 0.02-2.85; P = 0.25). Minor bleeding (without discontinuation of medical therapy) occurred in six patients (26.1%) in the rivaroxaban group versus six patients (28.6%) in the warfarin group (RR 0.88; 95% CI 0.23-3.32; P = 0.85). One patient in the warfarin group died from myocardial infarction. No cases of hemorrhagic stroke, valve thrombosis, peripheral embolic events, or new intracardiac thrombus were related in both groups. CONCLUSIONS: In this pilot study, rivaroxaban 15 mg twice daily had thromboembolic and bleeding events similar to warfarin in patients with mechanical heart valves. These data confirm the authors' proof-of-concept and suggest that a larger trial with a similar design is not unreasonable. CLINICALTRIAL. GOV IDENTIFIER: NCT03566303.

Association Between Epicardial Adipose Tissue and Stroke.

Epicardial adipose tissue (EAT) is correlated with endothelial dysfunction, metabolic syndrome, increased mortality and recent studies showed a possible association with the increased risk of stroke. We performed a systematic review of studies evaluating the association between EAT and stroke. Eighty studies met the inclusion criteria and were consequently analyzed. The review had Five main findings. First, the increased epicardial fat thickness (EFT) may be associated with the stroke episode. Second, regardless of the imaging method (echocardiography, MRI, and CT) this association remains. Third, the association of metabolic syndrome and atrial fibrillation seems to increase the risk of stroke. Fourth, this systematic review was considered as low risk of bias. Despite being unable to establish a clear association between EAT and stroke, we have organized and assessed all the research papers on this topic, analyzing their limitations, suggesting improvements in future pieces of research and pointing out gaps in the literature. Furthermore, the mechanistic links between increased EAT and stroke incidence remains unclear, thus, further research is warranted.
