Aquatic exercise for people with asthma: a systematic review with meta-analysis of randomized controlled trials.

INTRODUCTION: Aquatic exercises are among the types of exercise most tolerated by people with asthma. Therefore, the objective of this study was to synthesize the evidence on the effects of aquatic exercise on lung function and quality of life in asthmatic patients. DATA SOURCES: A systematic search encompassing the Medline, CINAHL, Cochrane Library, Embase, AMED, SPORTDiscus, and Physiotherapy Evidence Database databases was conducted to identify randomized controlled trials assessing the impact of aquatic exercise in comparison to control conditions or land-based exercise on lung function and quality of life in individuals diagnosed with asthma. STUDY SELECTIONS: The stages of selection, data extraction and methodological evaluation, and level of evidence of the manuscripts were carried out independently by two authors. RESULTS: Ten studies, comprising a total of 393 participants, were incorporated into this systematic review. Very low-quality evidence was found in favor of aquatic exercise in asthmatic patients for forced expiratory volume in 1 s (MD: 0.20 L, 95% CI: 0.02 L-0.38L N: 91) and for forced vital capacity (MD: 0.32 L, 95% CI: 0.08 L-0.56L N: 80). No effect of aquatic exercise was observed on the FEV1/FVC ratio (MD:1.11L, 95% CI: -1.28 L-3.49L N:80) compared with control. Only one study evaluated the effect of aquatic exercise on patients' quality of life. CONCLUSIONS: Improvements in lung function and quality of life in asthmatic patients undergoing aquatic exercise are not supported by high-quality evidence. The present findings will need to be confirmed by new, methodologically more rigorous clinical trials.

The effect of aquatic exercise on pulmonary function and quality of life in asthma patients is still uncertain.The current quality of evidence for aquatic exercise in asthma patients is low.There is an urgent need for higher-quality studies investigating the effects of aquatic exercise among asthma patients.

Assessment of health-related quality of life in patients with Chagas cardiomyopathy using Minnesota living with heart failure questionnaire: A validation study.

OBJECTIVE: Chagas cardiomyopathy (ChC) is the most severe clinical form of Chagas disease and, in association with psychosocial factors, can compromise the health-related quality of life (HRQoL) of affected patients. To date, there is no specific instrument to assess the HRQoL of these patients, and the Minnesota Living with Heart Failure Questionnaire (MLwHFQ), specific for heart failure, is being used both in research and current clinical practice. Therefore, we aimed to verify the validity of the MLwHFQ in the assessment of HRQoL of patients with ChC. METHODS: Fifty patients with ChC (50.6 ± 10.1 years, NYHA I-III) were evaluated. The MLwHFQ, Short-Form of Health Survey (SF-36), Beck Depression Inventory (BDI), and Human Activity Profile (HAP) were applied. All patients underwent echocardiography and Cardiopulmonary Exercise Testing (CPET). RESULTS: The MLwHFQ score correlated with almost all SF-36 domains (with r-value ranging from -0.38 to -0.69), except pain (p = 0.118). The MLwHFQ score also correlated with the BDI score (r = 0.748; p < 0.001), HAP score (r = -0.558; p = 0.001), peak oxygen uptake (r = -0.352; p = 0.01), and left ventricular ejection fraction (r = -0.329; p = 0.021). There was no significant difference in the score found on the MLwHFQ among NYHA classes (p = 0.101), as well as between patients with systolic dysfunction (n = 30) and preserved cardiac function (n = 20) (p = 0.058). Similarly, there was no significant difference in the score found on the physical (p = 0.423) and mental (p = 0.858) components of SF-36 between patients with systolic dysfunction and preserved cardiac function (p = 0.271 and p = 0.609, respectively). There was also no difference in the mental component of SF-36 among NYHA classes (p = 0.673). However, the HRQoL using the physical component of SF-36 was worse in advanced NYHA classes (p = 0.014). CONCLUSION: MLwHF correlated with most SF-36 HRQoL domains, depressive symptoms, physical activity, and systolic function and seems to be valid in assessing the HRQoL of ChC patients.

Reliability and validity of the Patient Generated Index (PGI) in patients with chronic kidney disease (CKD) on dialysis, a new approach to quality of life.

PURPOSE: To evaluate the test-retest reliability and validity of the Patient Generated Index (PGI) in individuals with Chronic Kidney Disease (CDK) undergoing hemodialysis. METHODS: Through a non-experimental study with repeated measures, PGI was applied twice to assess internal consistency and test-retest reliability. Correlations with the Kidney Disease Quality of Life Short Form (KDQOL-SF), the Human Activity Profile (HAP) questionnaire, the Social Participation Scale, and the Glittre ADL Test were used. RESULTS: 91 individuals with CKD were evaluated. There was high reliability for the PGI (ICC= 0.97) PGI correlated with KQDOL - SF in Functional Capacity r = 0.38 (p < 0.001), Emotional Well-Being r = 0.31 (p = 0.003), Social Aspect r = 0.22 (p = 0.036), Emotional Function r = 0.22 (p = 0.038) and Effect of Kidney Disease r = 0.21 (p = 0.042), and Physical scores r = 0.24 (p = 0.021)), Mental r = 0.21 (p = 0.05) and General r = 0.22 (p = 0.037) summarized. There was a significant correlation between PGI and HAP r = 0.40 (p < 0.001) and the Social Participation Scale r = -0.36 (p < 0.001). There was no correlation between the PGI and Glittre ADL scores r = 0.12 (p = 0.247). CONCLUSION: In adults receiving hemodialysis, the PGI proved to be an accurate and reliable instrument for the assessment of the quality of life from the perspective of the patient.IMPLICATIONS FOR REHABILITATIONAlthough hemodialysis treatment is associated with increased survival and symptom control, there is a significant change in the patient's lifestyle.In order to provide a more focused view of the individual, the Patient Generated Index (PGI) was created to evaluate the quality of life.PGI is reliable and correlates with KQDOL - SF and the Social Participation Scale in this population.

Functional predictors of poor outcomes in Chagas cardiomyopathy: The value of end-tidal carbon dioxide at peak exercise.

BACKGROUND: Functional impairment can be detected from the onset of heart disease in patients with Chagas cardiomyopathy (ChC) and the prognostic value of the end-tidal carbon dioxide at peak exercise (PETCO2 peak) should be investigated. OBJECTIVE: To verify the prognostic value of PETCO2 peak in patients with ChC. METHODS: Seventy-six patients with ChC (49.2 ± 9.8 years, NYHA I-III) were evaluated by echocardiography and Cardiopulmonary Exercise Testing. Patients were followed up to four years and the end-point was defined as cardiovascular death, stroke, or cardiac transplantation. RESULTS: At the end of the follow-up period (29.0 ± 16.0 months), 16 patients (21%) had experienced adverse events. The area under the receiver operating characteristic (ROC) curve to identify the risk of adverse events by PETCO2 peak in patients with ChC was 0.83 (95% CI: 0.69 to 0.97), and the value of 32 mmHg was the optimal cut point (70% of sensitivity and 85% of specificity). In the Kaplan-Meier diagram, there was a significant difference (p<0.001) between patients with reduced (≤ 32 mmHg) and preserved PETCO2 peak (>32 mmHg). In the final Cox multivariate model, only reduced PETCO2 peak (HR 4.435; 95% CI: 1.228 to 16.016, p = 0.023) and VO2peak (HR 0.869; 95% CI: 0.778 to 0.971, p = 0.013) remained as independent predictors of poor outcome in ChC patients. CONCLUSION: Reduced PETCO2 peak and VO2peak demonstrated valuable prognostic value in patients with ChC. The cutoff points for both functional variables can be used during risk stratification and may help in the development of therapeutic strategies in ChC patients.

Inflammatory biomarkers at different stages of Sarcopenia in older women.

In recent years, studies have found that Sarcopenia alters inflammatory biomarkers. However, the behavior of inflammatory biomarkers at different stages of Sarcopenia is not well understood. This study aimed to compare a broad panel of inflammatory biomarkers in older women at different stages of Sarcopenia. The study included 71 Brazilian community-dwelling older women. Muscle Strength was assessed by using handgrip strength (Jamar dynamometer). The Short Physical Performance Battery (SPPB) was performed to assess the physical performance, and body composition was assessed by DEXA. Sarcopenia was diagnosed and classified according to the EWGSOP2 criteria. Blood was drawn, and inflammatory biomarkers associated with Sarcopenia (IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, TNF, adiponectin, leptin, resistin, BDNF, sTNFr-1 and sTNFr-2) was analysed. After diagnosis and classification of sarcopenia, 45% of women did not present Sarcopenia (NS, N = 32), 23.9% were diagnosed with Sarcopenia Probable (SP, N = 17), 19,7% with Sarcopenia Confirmed (SC, N = 14), and 11.3% with Severe Sarcopenia (SS, N = 8). The analysis of inflammatory biomarkers revealed that the more advanced the stage of Sarcopenia, the higher the levels of BDNF, IL-8, sTNFr-1, and sTNFr-2. The assessment of BDNF, IL-8, sTNFr-1, and sTNFr-2 levels may be an adjuvant tool in diagnosis and severity classification of Sarcopenia in older Brazilian women.

Accuracy of handgrip and respiratory muscle strength in identifying sarcopenia in older, community-dwelling, Brazilian women.

Certain cut-off points for sarcopenia screening and diagnosis are arbitrary and based on European populations, with normative references often obtained from healthy young adults. Although respiratory skeletal muscle strength tests represent low-cost clinical measures commonly performed in clinical practice by health professionals, a gap remains regarding whether respiratory skeletal muscle strength tests are adequate and sensitive measures for sarcopenia screening. This study aimed to verify the value of handgrip and respiratory muscle strength as possible discriminators to identify sarcopenia and to establish cut-off points for sarcopenia screening in community-dwelling, Brazilian women. In a cross-sectional study, 154 community-dwelling, Brazilian women (65-96 years) were assessed for appendicular skeletal muscle mass, handgrip (HGS), and respiratory muscular strength, including maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP). The data were analyzed using the ROC curve and the Youden Index determined cut-off points. Statistical significance was set at 5%. 88 participants (57%) were sarcopenic. MEP (OR 0.98 [95%CI 0.97, 1.00], p = 0.023) and HGS (OR 0.82 [95% CI 0.75, 0.90], p < 0.001) were independent factors for sarcopenia in older. The optimal cut-off points for identifying sarcopenia were ≤ 77 cmH2O for MEP (AUC = 0.72), and ≤ 20 kg for HGS (AUC = 0.80). Simple muscular strength tests, including HGS and MEP, may be considered in the identification of sarcopenia in older, community-dwelling, Brazilian women. Future work is still needed to assess external validation of the proposed cut-offs before the clinical application.

Environmental opportunities facilitating cognitive development in preschoolers: development of a multicriteria index.

Access to environmental opportunities can favor children's learning and cognitive development. The objectives is to construct an index that synthesizes environmental learning opportunities for preschoolers considering the home environment and verify whether the index can predict preschoolers' cognitive development. A quantitative, cross-sectional, exploratory study was conducted with 51 preschoolers using a multi-attribute utility theory (MAUT). The criteria used for drawing up the index were supported by the literature and subdivided in Group A "Resources from the house" extracted from HOME Inventory including: (1) to have three or more puzzles; (2) have at least ten children's books; (3) be encouraged to learn the alphabet; (4) take the family out at least every 2 weeks. Group B "Screens" (5) caution with using television; (6) total screen time in day/minutes. Group C "Parental Schooling" (7) maternal and paternal education. Pearson correlation analyses and univariate linear regression were performed to verify the relationship between the established index with cognitive test results. The index correlated with the total score of the mini-mental state exam (MMC) and verbal fluency test (VF) in the category of total word production and word production without errors. Multicriteria index explained 18% of the VF (total word production), 19% of the VF (total production of words without errors) and 17% of the MMC. The present multicriteria index has potential application as it synthesizes the preschooler's environmental learning opportunities and predicts domains of child cognitive development.

Health-Related Quality of Life Reported by Patients With Chagas Disease: A Systematic Review of Qualitative Evidence With GRADE Recommendations.

Patients with Chagas disease have reduced health-related quality of life (HRQoL). Hence, we aimed to identify the factors that mostly affected their HRQoL. This was a systematic review of qualitative studies. The Latin American and Caribbean Health Sciences Literature, Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, Web of Science, and SciVerse Scopus databases were searched for relevant studies without language or date restrictions. The search and data analysis were performed by independent reviewers; all qualitative studies that reported the factors that had an impact on the HRQoL of patients with Chagas disease were included. The risk of bias was assessed using the Critical Appraisal Skills Program Qualitative Study Checklist; confidence in the evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation-Confidence in the Evidence from Reviews of Qualitative approach. Five studies were included in this review: four in Brazil and one in California, United States, with immigrants from Central and South America. The sample consisted of 207 patients with chronic Chagas disease. Stigma, physical limitations, work absenteeism, emotional or mental aspects, fear of treatment, and fear of the future had the strongest impact on the HRQoL. All items showed moderate confidence except for fear of treatment (low confidence). The physical, emotional, mental, and cultural aspects affected the HRQoL of patients with chronic Chagas disease. Identification of these factors is important in the development of strategies aimed at improving the HRQoL of this population.

Reliability and validity of specific quality of life assessment questionnaires related to chronic venous insufficiency: a systematic review.

This systematic review aimed to discuss the main findings regarding the reliability and validity of health-related quality of life questionnaires for chronic venous insufficiency. Searches were performed on the MEDLINE, CINAHL, Web of Science, LILACS, and Scopus databases. The search terms used were related to "venous insufficiency", and "quality of life". The CIVIQ-20 and CIVIQ-14 instruments had adequate internal consistency and both were able to discriminate disease severity. The VEINES-QoL showed adequate internal consistency but was not able to discriminate disease severity. Most studies did not demonstrate a correlation between VEINES-QoL and the mental component of the SF-36. The AVVQ had inadequate reliability but its validity was also doubtful when compared to the SF-36. The VARIShort demonstrated good internal consistency, reproducibility, and validity, but only the original study was included. For venous leg ulcers, the CCVUQ showed adequate reliability and validity when compared to VLU-QoL.

Esta revisão sistemática objetivou discutir os principais achados sobre a confiabilidade e validade dos questionários de qualidade de vida relacionada à saúde na insuficiência venosa crônica. A busca foi realizada nas bases de dados MEDLINE, CINAHL, Web of Science, LILACS e Scopus. Os termos de busca foram relacionados a "insuficiência venosa" e "qualidade de vida". O Chronic Lower Limb Venous Insufficiency Questionnaire (CIVIQ)-20 e o CIVIQ-14 apresentaram consistência interna adequada e foram capazes de discriminar a gravidade da doença. O Venous Insufficiency Epidemiological and Economic Study ­ Quality of Life (VEINES-QoL) apresentou consistência interna adequada, mas não foi capaz de discriminar a gravidade da doença. A maioria dos estudos não demonstrou associação do VEINES-QoL com o componente mental do Short Form Health Survey (SF-36). O Aberdeen Varicose Vein Questionnaire (AVVQ) apresentou confiabilidade inadequada e validade duvidosa quando comparado ao SF-36. O VARIShort demonstrou consistência interna, reprodutibilidade e validade boas, mas apenas o estudo original foi incluído. Na úlcera venosa, o Charing Cross Venous Ulcer Questionnaire (CCVUQ) apresentou confiabilidade e validade adequadas quando comparado ao Venous Leg Ulcer Quality of Life (VLU-QoL).

Double Product and Autonomic Function as Predictors of Quality of Life in Heart Transplant Recipients: A Cross-Sectional Study.

INTRODUCTION: Heart rate control by the autonomic nervous system (ANS) is impaired in heart transplant (HT) recipients, leading to increased resting heart rate, metabolic demand, and fatigue, which can impair their quality of life (QoL). In this study, we hypothesized the association of hemodynamics and autonomic function as predictors of QoL in HT recipients. METHODS: This is a cross-sectional study conducted with HT recipients aged ≥ 18 years at ambulatorial accompaniment. Blood pressure was used for hemodynamics assessment, and heart rate variability (HRV) was used for ANS assessment. QoL was assessed by the 36-item Short Form Health Survey. The significance level was set as P≤0.05. RESULTS: Twenty-two volunteers were included in the study. Systolic blood pressure (SBP) and double product (DP) were significantly negatively associated with the physical functioning domain of QoL. DP, the number of consecutive normal RR interval differences > 50 ms (NN50), and the percentage of normal RR intervals that differed by > 50 ms from the adjacent interval (PNN50) exhibited negative association with the physical role domain. NN50 and PNN50 were significantly associated with bodily pain, social functioning, and emotional role domains. SBP was negatively associated with the vitality domain. Considering general and mental health domains, no variable demonstrated significant association. DP, NN50, and PNN50 were negatively associated with the total score of QoL. CONCLUSION: This study demonstrated DP and HRV as predictors of QoL in HT recipients. These innovative results can become a relevant therapeutic target for improving QoL in HT recipients prior to its deterioration.

Association between executive functions and gross motor skills in overweight/obese and eutrophic preschoolers: cross-sectional study.

BACKGROUND: Preschool age (3-5 years old) is a crucial period for children to acquire gross motor skills and develop executive functions (EFs). However, the association between the qualitative gross motor skills and EFs remains unknown in preschoolers, especially among overweight and obese children. METHODS: This was a cross-sectional, exploratory, and quantitative study carried out on 49 preschool children, divided into two subgroups according to their body mass index (overweight/obese: 24; eutrophic [normal weight]: 25). The mean age was 4.59 years. More than half of the sample were boys (55%) and most of the mothers had completed high school (67%) and were class C socioeconomic level (63%). Gross motor skills were assessed using the Test of Gross Motor Development-2, while EFs were evaluated using Semantic verbal fluency (SVF), Tower of Hanoi (TH), Day/Night Stroop, and Delayed Gratification tests. Multiple linear regression models adjusted for sex, age, maternal education, socioeconomic status, quality of the home environment, and quality of the school environment using the stepwise method were executed, considering the cognitive tasks as independent variables and gross motor skills as dependent variable. RESULTS: The overweight/obese preschoolers showed worse locomotor skills than their eutrophic peers and below average gross motor quotient (GMQ). Overweight/obese girls performed worse in OC skills than boys with excess weight. SVF (number of errors) and TH (rule breaks) explained 57.8% of the variance in object control (OC) skills and 40.5% of the variance in GMQ (p < .05) in the overweight/obese children. Surprisingly, there was no significant association between any of the EF tasks and gross motor skills in the eutrophic children. CONCLUSION: A relationship between EF tasks (number of errors in SVF and rule breaks in TH) and gross motor skills (OC and GMQ) was demonstrated in the overweight/obese preschoolers, indicating that worse cognitive flexibility, working memory, planning, and problem solving are associated with worse gross motor skills in this population when compared to eutrophic children.

Efficacy of Acupuncture on Quality of Life, Functional Performance, Dyspnea, and Pulmonary Function in Patients with Chronic Obstructive Pulmonary Disease: Protocol for a Randomized Clinical Trial.

Chronic obstructive pulmonary disease (COPD) is a respiratory disease characterized by the presence of chronic airflow obstruction. Previous studies have evaluated the effect of acupuncture treatment (AT) in patients with COPD. Nevertheless, these studies show a great deal of heterogeneity in treatment protocols, having sample sizes that are too small to estimate and clarify effect size and heterogeneity in patients' baseline. The aim of this study is to evaluate the effectiveness of acupuncture on quality of life, functional performance, dyspnea, and pulmonary function in patients with COPD. As such, patients will go through the following three phases: Phase I-pretreatment: period of subject selection and inclusion in the protocol, with an interview and performance of exams and tests as follows: Mini-Cog, dual-energy X-ray absorptiometry, spirometry, the Patient-Generated Index, Saint George's Respiratory Questionnaire, the six-minute walk test, the London Chest Activity of Daily Living, and the COPD Assessment Test. Phase II-8 weeks of treatment, with AT 3 times a week, with two parallel groups: Group I-with 50 subjects-AT according to the recommended technical standards; Group II-with 50 subjects-Control, without acupuncture. Phase III-Continuation of AT for 8 weeks, maintaining the subjects in the previously allocated groups and following the same methodology.

The superior beneficial effects of exercise training versus hormone replacement therapy on skeletal muscle of ovariectomized rats.

Previous studies have highlighted the positive effects of Estradiol (E2) replacement therapy and physical exercise on skeletal muscle during menopause. However, the comparison effects of exercise training (ET) and estradiol replacement therapy during menopause on skeletal muscle have not been investigated to date. This study aimed to compare the effects of endurance exercise training versus E2 replacement therapy on mitochondrial density, redox status, and inflammatory biomarkers in the skeletal muscle of ovariectomized rats. Thirty female Wistar rats (12-week-old) were randomly assigned into three groups: Untrained ovariectomized rats (UN-OVX, n = 10); untrained ovariectomized rats treated with estradiol replacement therapy (E2-OVX); and, trained ovariectomized rats (TR-OVX). After ovariectomy, the E2-OVX rats were treated subcutaneously with E2 (implanted Silastic® capsule containing 360 µg of 17ß-estradiol/mL) while the TR-OVX group performed an exercise training protocol (50-70% of maximal running speed on a treadmill, 60 min/day, 5 days/week for 8 weeks). After euthanasia, the soleus muscle was processed for histological and biochemical evaluations. Only exercise prevented the reduction of maximal oxygen consumption and increased mechanical efficiency (ME). While mitochondrial muscle density, total antioxidant capacity (FRAP), catalase (CAT) activity, and interleukin 10 levels were higher in TR-OVX, only OVX-E2 presented higher CAT activity and lower interleukin 6 levels. Endurance exercise training compared with E2 replacement therapy maintains the aerobic capacity improving the ME of OVX rats. In addition, only endurance exercise training raises the skeletal muscle mitochondrial content and tends to balance the redox and inflammatory status in the skeletal muscle of OVX rats.

Determinants of High Fat Mass Index in Preschoolers Living in Brazilian Urban Areas.

OBJECTIVE: Determine the social, environmental, and personal factors associated with high fat mass index in preschoolers. DESIGN: A quantitative, exploratory, and cross-sectional study. SETTING AND PARTICIPANTS: Fifty-one Brazilian preschoolers from public schools living in urban areas. MAIN OUTCOME MEASURE(S): The preschoolers' fat mass index was determined using dual-energy radiological absorptiometry. The quality of home and school environments were accessed using the Early Childhood Home Observation for Measurement of the Environment and Early Childhood Environment Rating Scales. The physical activity levels were recorded by accelerometers. The daily energy intake was recorded and sociodemographic data using the Brazilian Economic Classification criterion. Data on exposure time to screens and parental obesity were collected according to the parents' reports. ANALYSIS: Data analyses were performed using simple and multiple regressions models. RESULTS: Parental obesity (ß, 0.516; 95% confidence interval [CI], 2.078-5.133), high quality of environmental stimulation of home (ß, 0.429; 95% CI, 1.294-4.023), and high exposure time to screens (ß, 0.256; 95% CI, 0.215-2.554) explained 43% of preschoolers' high fat mass index. CONCLUSIONS AND IMPLICATIONS: Identification of parental obesity, high quality of environmental stimulation of home, and high exposure time to screens as the most important determinants of the high fat mass index in preschoolers from Brazilian urban areas.

The health-related quality of life in patients with Chagas disease: the state of the art.

Chagas disease (CD) is a neglected tropical disease associated with poverty in which patients are surrounded by stigma. These factors can contribute to reducing health-related quality of life (HRQoL). Therefore, a broad discussion of HRQoL in the CD population is required. This study aimed to discuss the main findings of HRQoL in patients with CD, focusing on the association between sociodemographic and lifestyle factors, echocardiographic and functional determinants, and the effect of non-invasive interventions on HRQoL. A literature search of the MEDLINE, Web of Science, CINAHL, Scopus, and LILACS databases was performed with no data or language restrictions. Twenty-two articles were included in this meta-analysis. In general, HRQoL is worse in patients with CD than in healthy individuals, particularly in the presence of cardiovascular and/or gastrointestinal symptoms. Sex, age, functional class, level of physical activity, healthy habits, and medications received could affect HRQoL. Among the echocardiographic and functional determinants, decreased systolic function seems to negatively affect HRQoL. No association with the peak oxygen uptake was observed in the maximal tests. By contrast, well-tolerated field tests with submaximal intensities were associated with HRQoL. Both pharmaceutical care and exercise training have a positive effect on the HRQoL of patients with Chagas cardiomyopathy, and the mental component can be a prognostic marker in this population. In conclusion, assessment of HRQoL can provide important information about the health status of patients with CD, and its use in clinical practice is warranted.

The health-related quality of life in patients with post-COVID-19 after hospitalization: a systematic review.

Symptoms in post-COVID-19 patients who require hospitalization can persist for months, significantly affecting their health-related quality of life (HRQoL). Thus, the present study aimed to discuss the main findings regarding HRQoL in post-COVID-19 patients who required hospitalization. An electronic search was performed in the MEDLINE, EMBASE, CINAHL, Web of Science, LILACS, and Scopus databases, without date and language restrictions, until July 2021. Twenty-four articles were included in the analysis. It seems that HRQoL partially improved soon after hospital discharge, although the negative impact on HRQoL may persist for months. The physical and mental aspects are affected because patients report pain, discomfort, anxiety, and depression. The HRQoL of COVID-19 infected patients was worse than that of uninfected patients. Additionally, HRQoL seemed worse in patients admitted to the intensive care unit than in those who remained in the ward. Improvements in HRQoL after hospital discharge are independent of imaging improvement, and there seems to be no association between HRQoL after hospital discharge and disease severity on hospital admission. Many factors have been identified as determinants of HRQoL, with women and advanced age being the most related to worse HRQOL, followed by the duration of invasive mechanical ventilation and the need for intensive care. Other factors included the presence and number of comorbidities, lower forced vital capacity, high body mass index, smoking history, undergraduate education, and unemployment. In conclusion, these findings may aid in clinical management and should be considered in the aftercare of patients.

Is body fat mass associated with worse gross motor skills in preschoolers? An exploratory study.

We compared the motor competence between overweight/obese and eutrophic preschoolers with similar physical activity levels, age, socioeconomic status, maternal education, quality of the home environment and quality of the school environment. We also investigated to what extent excess body fat mass explains gross motor skills in preschoolers. A cross-sectional quantitative and exploratory study was conducted with 48 preschoolers assigned into eutrophic and overweight/obese groups. Overweight/obese preschoolers had worse Locomotor subtest standard scores than the eutrophic ones (p = 0.01), but similar Object Control subtest and Gross Motor Quotient scores (p > 0.05). Excess body fat mass explained 12% of the low Locomotor subtest standard scores in preschoolers (R2 = 0.12; p = 0.007). Excess body fat mass was associated with worse locomotor skills when the model was adjusted for physical activity levels, age, socioeconomic status, maternal education, quality of the home environment and quality of the school environment. Thus, excess body fat mass partly explains lower locomotor skills in preschoolers.

Physical environmental opportunities for active play and physical activity level in preschoolers: a multicriteria analysis.

BACKGROUND: Active play opportunities seems to influence the level of physical activity during childhood. However, a gap remains about which environmental opportunities including the daycare physical environment could have a positive impact on the level of physical activity in preschoolers. OBJECTIVES: (1) To develop an index to measure the environmental opportunities of free active play for preschoolers of middle-income countries; (2) to check the relationship and contribution of the index to explain objectively the level of physical activity. METHODS: A quantitative, cross-sectional, exploratory study with 51 preschool children. The established criteria for the index according to the literature were: (1) Outdoor time on typical days of the week. (2) Outdoor time on a typical weekend day. (3) The presence of internal space and external environment in the child's home that allows playing. (4) Presence of patio with space for games at the school. (5) Presence of a playground with a toy at the school. We applied multi-attribute utility theory for the determination of the multicriteria index of physical environmental opportunities. Pearson's correlation analysis and simple linear regression were used to verify the association between the index and the physical activity level. RESULTS: The index showed a positive correlation with the level of physical activity, e.g., the average time of MVPA (r = 0.408, p = 0.003). The univariate linear regression demonstrated that the quality of physical environmental opportunities for physical activity explained 20% of the preschooler's classification as active and 16% of the time in moderate to vigorous physical activity (p < 0.001). CONCLUSION: Physical environmental opportunities for active play have a positive effect on physical activity in preschoolers and should be encouraged in different social segments.

The Glittre activities of daily living as a potential test for functional evaluation of patients on hemodialysis: a validation study.

PURPOSE: To investigate the validity and within-day reliability of the Glittre activities of daily living test (Glittre ADL-test) in patients on hemodialysis. METHODS: Ninety-one patients on hemodialysis were evaluated using Glittre ADL-test, functional tests, health-related quality of life, human activity profile, and social participation. Convergent validity was analyzed by the correlation analysis. The Glittre ADL-test results were compared among different levels of the functional tests, human activity profile, and participation (known-groups validity). Within-day reliability was examined by Intra-class Correlation Coefficient (ICC). RESULTS: There was a significant moderate to strong correlation between Glittre ADL-test and functional tests (r = 0.62 to 0.66 and -0.70 to -0.44). A significant weak correlation was found between Glittre ADL-test, health-related quality of life (r = 0.28 to 0.32), and human activity profile (r=-0.33). There was no significant correlation with participation. Except for participation level, the Glittre ADL-test results were able to identify individuals with low performance in all evaluated tests and were able to differentiate among inactive and active individuals by human activity profile (p < 0.05). Within-day reliability was evaluated in 42 patients. The ICC was 0.97. CONCLUSION: The Glittre ADL-test is a reliable test associated with functional parameters and physical aspects related to health-related quality of life, with potential value in the functional evaluation of patients on hemodialysis.Implications for rehabilitationFunctional impairment is a common clinical finding and is an important predictor of poor prognosis in patients on hemodialysis.The Glittre ADL-test has excellent within-day reliability and is a valid instrument for functional assessment in patients on hemodialysis.Activity limitations of patients on hemodialysis can be assessed by Glittre ADL-test.
