Effects of photobiomodulation and an aerobic exercise on the level of pain and quality of life in women with fibromyalgia

To evaluate the effectiveness of photobiomodulation (PBM) in conjunction with an aerobic exercise program (AEP) on the level of pain and quality of life of women with fibromyalgia (FM).

METHODS

A double-blinded randomized controlled trial in which 51 participants with FM were allocated into 4 groups: control group (CG) (n = 12); active PBM group (APG) (n = 12); AEP and placebo PBM group (EPPG) (n = 13); AEP and active PBM group (EAPG) (n = 14). AEP was performed on an ergometric bicycle; and a PBM (with an increase dosage regime) [20 J, 32 J and 40 J] was applied using a cluster device. Both interventions were performed twice a week for 12 weeks. A mixed generalized model analysis was performed, evaluating the time (initial and final) and group (EAPG, EPPG, APG and CG) interaction. All analyses were based on intent-to-treat for a significance level of p ≤ 0.05.

RESULTS

The intra-group analysis demonstrated that all treated groups presented a significant improvement in the level of pain and quality of life comparing the initial and final evaluation (p < 0.05). Values for SF-36 and 6-minute walk test increased significant in intragroup analysis for EPPG comparing the initial and final evaluation. No intergroup differences were observed.

CONCLUSIONS

Both exercised and PBM irradiated volunteers present improvements in the variables analyzed. However, further studies should be performed, with other PBM parameters to determine the best regime of irradiation to optimize the positive effects of physical exercises in FM patients.

Anodal tDCS over the motor cortex improves pain but not physical function in chronic chikungunya arthritis: Randomized controlled trial

BACKGROUND

Chikungunya virus (CHIKV) is a globally prevalent pathogen, with outbreaks occurring in tropical regions. Chronic pain is the main symptom reported and is associated with decreased mobility and disability. Transcranial direct current stimulation (tDCS) is emerging as a new therapeutic tool for chronic arthralgia.

OBJECTIVE

To evaluate the effectiveness of 10 consecutive sessions of anodal tDCS on pain (primary outcome) in participants with chronic CHIKV arthralgia. Secondary outcomes included functional status, quality of life, and mood.

METHODS

In this randomized, double-blind, placebo-controlled trial, 30 participants with chronic CHIKV arthralgia were randomly assigned to receive either active (n = 15) or sham (n = 15) tDCS. The active group received 10 consecutive sessions of tDCS over M1 using the C3/Fp2 montage (2 mA for 20 min). Visual analog scale of pain (VAS), health assessment questionnaire (HAQ), short-form 36 health survey (SF-36), pain catastrophizing scale, Hamilton anxiety scale (HAS), timed up and go (TUG) test, lumbar dynamometry, 30-s arm curl and 2-min step test were assessed at baseline, day 10 and at 2 follow-up visits.

RESULTS

There was a significant interaction between group and time on pain (p = 0.03; effect size 95 % CI 0.9 (-1.67 to -0.16), with a significant time interaction (p = 0.0001). There was no interaction between time and group for the 2-minute step test (p = 0.18), but the groups differed significantly at day 10 (p = 0.01), first follow-up (p = 0.01) and second follow-up (p = 0.03). HAQ and SF-36 improved but not significantly. There was no significant improvement in mental health, and physical tests.

CONCLUSION

tDCS appears to be a promising intervention for reducing pain in participants with chronic CHIKV arthralgia, although further research is needed to confirm these findings and explore potential long-term benefits.

Long-term reduced functional capacity and quality of life in hospitalized COVID-19 patients

Background

Persistent symptoms and exercise intolerance have been reported after COVID-19, even months after the acute disease. Although, the long-term impact on exercise capacity and health-related quality of life (HRQoL) is still unclear.

Research question

To assess the long-term functional capacity and HRQoL in patients hospitalized due to COVID-19.

Study design and methods

This is a prospective cohort study, conducted at two centers in Brazil, that included post-discharge COVID-19 patients and paired controls. The cohort was paired by age, sex, body mass index and comorbidities, using propensity score matching in a 1:3 ratio. Patients were eligible if signs or symptoms suggestive of COVID-19 and pulmonary involvement on chest computed tomography. All patients underwent cardiopulmonary exercise testing (CPET) and a HRQoL questionnaire (SF-36) 6 months after the COVID-19. The main outcome was the percentage of predicted peak oxygen consumption (ppVO2). Secondary outcomes included other CPET measures and HRQoL.

Results

The study sample comprised 47 post-discharge COVID-19 patients and 141 healthy controls. The mean age of COVID-19 patients was 54 ± 14 years, with 19 (40%) females, and a mean body mass index of 31 kg/m2 (SD, 6). The median follow-up was 7 months (IQR, 6.5-8.0) after hospital discharge. PpVO2 in COVID-19 patients was lower than in controls (83% vs. 95%, p = 0.002) with an effect size of 0.38 ([95%CI], 0.04-0.70). Mean peak VO2 (22 vs. 25 mL/kg/min, p = 0.04) and OUES (2,122 vs. 2,380, p = 0.027) were also reduced in the COVID-19 patients in comparison to controls. Dysfunctional breathing (DB) was present in 51%. HRQoL was significantly reduced in post COVID patients and positively correlated to peak exercise capacity.

Interpretation

Hospitalized COVID-19 patients presented, 7 months after discharge, with a reduction in functional capacity and HRQoL when compared to historical controls. HRQoL were reduced and correlated with the reduced peak VO2 in our population.

Does the intensity of pain and disability affect health-related quality of life of older adults with back pain? Multilevel analysis between Brazil and Netherlands: a cross-sectional study of the BACE consortium

BACKGROUND

The prognosis of back pain (BP) in the older adults is less favorable than in younger adults and progress to adverse outcomes and consequent worsening of health-related quality of life (HRQoL). The present study aimed to verify the association between BP intensity, disability and HRQoL in older adults residents in Brazil and Netherlands, and to evaluate whether the country of residence influences the associations.

METHODS

Data were collected from 602 Brazilian and 675 Dutch participants with a new episode of BP from the Back Complaints in Elders (BACE) consortium. For the present study, a cross section was used. Pain intensity and disability were assessed using the Numerical Rating Scale (NRS) and the Roland-Morris Disability Questionnaire (RMDQ), respectively. HRQoL was assessed using the Short Form Health Survey (SF-36) quality of life questionnaire. Age, sex, and education were descriptive variables. Pain intensity (NPS score) and country were the independent variables and quality of life assessed by each SF domain - 36 was the dependent variable. Analysis of models at the individual level was performed to verify the association between pain and disability, also HRQoL in Netherlands and Brazil in the total sample. The multilevel model was used to verify whether the older adults person's country of residence influenced this relationship.

RESULTS

The average age of the participants was 67.00 (7.33) years. In the total sample, linear regression analysis adjusted for sex and age showed a significant association between BP intensity scores and HRQoL, for all domains. There was no association between disability and HRQoL. In the multilevel analysis, there was an association between BP intensity and HRQoL in all domains and an association between the country of residence and HRQoL, influencing the effect of pain, in all domains, except for the physical functioning.

CONCLUSION

Socioeconomic and cultural aspects of different countries can affect the perception of the elderly about their HRQoL in the presence of BP. Pain and disability in Brazilian and Dutch older adults ones are experienced differently in relation to their HRQoL.

Clinical, tomographic and functional comparison of sporadic and tuberous sclerosis complex-associated forms of lymphangioleiomyomatosis: a retrospective cohort study

Background

Lymphangioleiomyomatosis (LAM) is a rare disease that can occur sporadically (S-LAM) or associated with the tuberous sclerosis complex (TSC-LAM). The natural history of LAM is not completely understood, including whether there is a difference between the clinical courses of the two forms. This study aimed to compare the clinical, functional and tomographic features between S-LAM and TSC-LAM, and evaluate the annual rates of change in lung function.

Methods

This retrospective cohort study included patients with LAM followed up between 1994 and 2019. Clinical, functional and imaging variables were evaluated, and the lung cysts were automatically quantified. Quality of life and predictors of lung function impairment were accessed, and the annual rate of lung function decline was compared between S-LAM and TSC-LAM.

Results

Of the 107 patients included, 77 had S-LAM and 30 had TSC-LAM. Although patients with TSC-LAM had a higher prevalence of renal angiomyolipomas and neurological and dermatological manifestations, pulmonary function tests were similar. Patients with S-LAM had a greater rate of forced expiratory volume in 1 s decline and a higher extent of cysts. Pneumothorax, desaturation in the 6-minute walking test and a higher extent of lung cysts were predictors of functional impairment. A greater impact on vitality and emotional health was observed in the TSC-LAM.

Conclusion

Greater functional decline and a higher cystic extension were found in patients with S-LAM. Our study provides a broad clinical, functional and tomographic characterisation of patients with LAM, adding valuable information to the existing evidence to better understand the two forms of the disease.

Sex differences in the impact of musculoskeletal disorders on health-related quality of life: a population-based study, Campinas, SP - ISACamp 2014/15

This article aims to estimate the prevalence of musculoskeletal disorders (MD) on the adult population of Campinas, São Paulo, Brazil, verifying associated demographic and socioeconomic factors, and to analyze their impact on Health-Related Quality of Life (HRQoL) according to sex. A population-based study was conducted with 2,166 individuals using data from the ISACamp 2014/15. The Medical Outcomes Study SF-36-Item Short Form Health Survey (SF-36) was used to measure HRQoL according to MD. Prevalence ratios (PR) were estimated by Poisson regression. Musculoskeletal disorders had a prevalence of 8.5% (6.7% tendonitis and 2.7% work-related musculoskeletal disorders - WMSD). Results showed a higher prevalence of musculoskeletal disorders in women, active or on leave due to illness, and in individuals with higher education levels. Moreover, reduced HRQoL scores were observed in 6 of the 8 domains, due to MD. The mental component and physical component showed greater impairment respectively among women and men after self-reported WMSD. These findings point to substantial damage from musculoskeletal disorders on the population's HRQoL. WMSD affect the HRQoL of men and women distinctly.

Botulinum toxin-A effects on pain, somatosensory and psychosocial features of patients with refractory masticatory myofascial pain: a randomized double-blind clinical trial

The antinociceptive effect of BoNT-A have been well documented in animal studies; however, results of few but well-designed randomized placebo-controlled clinical trials about BoNT-A efficacy in masticatory myofascial pain (MFP) are inconsistent. Therefore, the present randomized, double-blind, placebo-controlled clinical trial evaluated the efficacy of BoNT-A in patients with refractory MFP. Twenty-eight patients with pain reduction of less than 30% despite conservative treatment and with an average pain intensity of > 50 mm on the visual analogue scale (VAS) participated. Patients were randomly assigned to receive a total of 80 U of BoNT-A or saline solution (SS) injected into the masseter and anterior temporalis muscles. Pain intensity (VAS), quantitative sensory testing (QST), conditioned pain modulation (CPM), and psychosocial status were examined. Follow-up was performed at 1 and 6 months. For repeated-measure comparisons between evaluation times, Friedman test with Bonferroni correction was used for pain and somatosensory variables and the Wilcoxon test for the psychosocial variables. The Mann-Whitney test was used for all comparisons between groups. The BoNT-A group had a significant decrease in pain intensity at follow-ups compared with the SS group (p < 0.001). QST assessment revealed higher pressure pain threshold values in the masseter muscle for BoNT-A group compared to SS (p < 0.03) at all follow-ups. No differences were found for mechanical pain threshold and wind-up ratio values (p > 0.05) in the entire study. The BoNT-A group presented the most efficient CPM effect (p < 0.03) only at the 1 month follow-up in the masseter muscle. There was a significant time effect for BoNT-A in all psychosocial variables (p < 0.05) and a drug effect in the Central Sensitization Inventory (p < 0.01), Pittsburgh Sleep Quality Index (p < 0.004), and Healthy Survey 36 (p < 0.05) at 6 months follow-up. The study demonstrates that a single injection-session of BoNT-A has positive effects on the hall pain spectrum of patients with refractory masticatory myofascial pain.

The Association between Perceived Stress, Quality of Life, and Level of Physical Activity in Public School Teachers

Chronic high stress levels related to work impact the quality of life (QoL). Although physical activity improves QoL, it is not clear whether this life study habit could attenuate possible relationships between QoL and stress in public school teachers. The sample for this study was made up of 231 teachers from public schools. QoL was assessed using the Short-Form Health Survey and physical activity via Baecke's questionnaire. A Likert scale assessed stress level perception. Poisson Regression analyzed the association between stress level and QoL domains adjusted for sex, age, and socioeconomic conditions (model 1). In model 2, physical activity level was inserted in addition to model 1. Seven out of eight domains of QoL, except the domain of pain, were associated with high levels of stress (all p < 0.05-model 1). However, in model 2, the associations of the high levels of stress with general health status (p = 0.052) and functional capacity (p = 0.081) domains of QoL were mitigated. Our results indicated that physical activity mitigated the relationship between higher levels of stress and lower perception of general health status and functional capacity domains in secondary public school teachers.

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.

Quality of life in parents of Turkish and Syrian pediatric bone marrow transplant and oncology patients

Background

The success of the treatment depends on the well-being of the parents in pediatric cancer patients. In addition, migrants need to deal with the consequences of war.

Aim

Our purpose was to compare the HRQoL of parents of Syrian and Turkish children followed in our bone marrow transplant and oncology units.

Materials and Methods

One hundred SF 36 questionnaires, fifty from each group were collected between October 2019 and March 2020 in this cross-sectional study. Demographic characteristics of the patients (sex, age, cancer type, presence of relapse, duration of follow-up) and education level of parents were recorded. Analyses were performed using IBM SPSS Statistics version 20.0.

Results

Turkish parents reported better results in physical functioning, emotional well-being, physical pain, general health, and physical health composite score (P < 0.05). There were more fathers in the Syrian group and education status was significant between the two groups (P = 0.01, P = 0.001, respectively). There was no correlation between QoL and education levels in the Turkish group. In Syrian parents, pain score was high in middle school graduates (P = 0.043). In the presence of relapse, although the physical function score decreased, the physical role function score increased in Turkish parents (P = 0.0035, P = 0.005, respectively). Syrian parents' emotional role function and energy/fatigue score were both increased when children had relapses (P = 0.027for both).

Conclusion

Migration is a complex issue. Turkish parents were better in physical functioning, emotional well-being, physical pain, general health, and physical health composite score. Screening for parental burden, assisting them to find appropriate support services is essential in improving the health and QoL of both our patients and their parents.

Effects of a 16-week home-based exercise training programme on health-related quality of life, functional capacity, and persistent symptoms in survivors of severe/critical COVID-19: a randomised controlled trial

BACKGROUND

Long-lasting effects of COVID-19 may include cardiovascular, respiratory, skeletal muscle, metabolic, psychological disorders and persistent symptoms that can impair health-related quality of life (HRQoL). We investigated the effects of a home-based exercise training (HBET) programme on HRQoL and health-related outcomes in survivors of severe/critical COVID-19.

METHODS

This was a single-centre, single-blinded, parallel-group, randomised controlled trial. Fifty survivors of severe/critical COVID-19 (5±1 months after intensive care unit discharge) were randomly allocated (1:1) to either a 3 times a week (~60-80 min/session), semi-supervised, individualised, HBET programme or standard of care (CONTROL). Changes in HRQoL were evaluated through the 36-Item Short-Form Health Survey, and physical component summary was predetermined as the primary outcome. Secondary outcomes included cardiorespiratory fitness, pulmonary function, functional capacity, body composition and persistent symptoms. Assessments were performed at baseline and after 16 weeks of intervention. Statistical analysis followed intention-to-treat principles.

RESULTS

After the intervention, HBET showed greater HRQoL score than CONTROL in the physical component summary (estimated mean difference, EMD: 16.8 points; 95% CI 5.8 to 27.9; effect size, ES: 0.74), physical functioning (EMD: 22.5 points, 95% CI 6.1 to 42.9, ES: 0.83), general health (EMD: 17.4 points, 95% CI 1.8 to 33.1, ES: 0.73) and vitality (EMD: 15.1 points, 95% CI 0.2 to 30.1, ES: 0.49) domains. 30-second sit-to-stand (EMD: 2.38 reps, 95% CI 0.01 to 4.76, ES: 0.86), and muscle weakness and myalgia were also improved in HBET compared with CONTROL (p<0.05). No significant differences were seen in the remaining variables. There were no adverse events.

CONCLUSION

HBET is an effective and safe intervention to improve physical domains of HRQoL, functional capacity and persistent symptoms in survivors of severe/critical COVID-19.

Influence of pain on the quality of life in patients with venous ulcers: Cross-sectional association and correlation study in a brazilian primary health care lesions treatment center

We aimed to verify the association and correlation between pain and QoL in people with VU treated in a Brazilian Primary Health Care (PHC) lesions treatment center. This is an observational, cross-sectional study with a quantitative approach, carried out in a service specialized in the treatment of chronic injuries, linked to 29 PHC units. Sociodemographic and health characterization instruments were used. The Short Form Health Survey-36 (SF-36) and Visual Analogue Pain Scale (VAPS) also were used. The Kruskal-Wallis test verified the association between the scalar variables of QoL and pain intensity. With Spearman's correlation test, we verified the level of correlation between the scales applied. A total of 103 patients participated in the study. Higher QoL scores associated with moderate pain were found, especially in the Physical role functioning, Physical functioning, and Vitality domains. Correlation analysis showed its greatest (moderate) strength in the interaction between the highest scores in the Physical role functioning and Emotional role functioning domains with the lowest pain levels.

Neuropsychological and quality of life outcomes in PKU patients: expert recommendations of assessment tools in Brazil

BACKGROUND

 Phenylketonuria (PKU) is an inborn error of metabolism caused by deficient activity of phenylalanine hydroxylase. In Brazil, the National Neonatal Screening Program enables early treatment of patients with PKU, which prevents them from developing severe neurological damage and mental disabilities. However, between 20 and 30% of early-treated patients with PKU present focal cognitive deficits, including deficits in working memory, processing speed, and psychiatric symptoms such as anxiety, depression, and attention deficit hyperactivity disorder (ADHD). Therefore, age-specific neuropsychiatric and cognitive tests are important components of PKU patient care. To date, there are no officially approved guidelines or recommendations of tools in Portuguese validated for use in Brazil that could be applied to assess these parameters in patients with PKU.

OBJECTIVE

 To recommend tools validated for use in Brazil that can be used in daily clinical practice to assess quality of life and neuropsychological outcomes in patients with PKU.

METHODS

 Six Brazilian experts discussed about eligible tools based on their clinical experience, the feasibility of their use in clinical routines, and their availability in public health services. Before the meeting, an independent review of the literature was conducted to identify the currently validated tools in Brazil, using the MEDLINE and SciELO databases.

RESULTS

 The experts recommended nine tools to assess quality of life (Peds-QL, SF-36 or WHOQOL-bref), executive function (BRIEF or Bayley-III), IQ (SONR 2½-7[a] or WASI) and ADHD (MTA-SNAP-IV and ASRS).

CONCLUSION

 These instruments may be easily incorporated into clinical practice and improve the quality of multidisciplinary care of patients with PKU.

Obstructive Sleep Apnea in Adults with Treacher Collins Syndrome is Related with Altered Anthropometric Measurements, Increased Blood Pressure and Impaired Quality of Life

Objectives  This study aimed at evaluating the risk for obstructive sleep apnea (OSA) and its frequency in adults with Treacher Collins syndrome (TCS). The association of OSA with excessive daytime sleepiness (EDS), respiratory symptoms, and clinical variables was also assessed. Material and Methods  The subjects were prospectively screened for OSA through the Berlin Questionnaire and type I polysomnography. The Epworth Sleepiness Scale and the Respiratory Symptoms Questionnaire were used for assessing OSA-related symptoms. Quality of life was assessed by means of the Short Form 36 Health Survey. Results  The sample comprised 20 adults with TCS (55.0% female), aged 22.6 ± 5.8 years. Mean values of systemic blood pressure (113.0 ± 12.6/68.0 ± 9.5mmHg), body mass index (22.9 ± 5.9kg/m ² ), neck (34.1 ± 4.3cm), and waist circumference (80.4 ± 13.6cm) characterized the sample. A high risk for OSA was detected in 35% of the sample. Polysomnography results indicated an OSA frequency of 44.4%, with a median apnea-hypopnea index (AHI) value of 3.8 events/hour (minimum = 0.2; maximum = 77.5). Snoring (75.0%), nasal obstruction (70.0%) and EDS (20.0%) were the reported OSA-related symptoms. Quality of life median scores were 72.3 points (minimum = 45.0; maximum = 91.1). Strong positive correlations between AHI versus waist circumference and AHI versus systolic blood pressure were found. Moderate positive correlations between AHI versus body mass index and AHI versus neck circumference were detected. Negative correlation between AHI versus vitality were also observed. Conclusion  Adults with TCS are at high risk for OSA, which is associated with respiratory symptoms, altered anthropometric measurements, increased systolic pressure and impairment of quality of life.

Impact of impaired pulmonary function on clinical outcomes in survivors of severe COVID-19 without pre-existing respiratory disease

OBJECTIVE

To investigate the impact of impaired pulmonary function on patient-centered outcomes after hospital discharge due to severe COVID-19 in patients without preexisting respiratory disease.

METHODS

This is an ongoing prospective cohort study evaluating patients (> 18 years of age) 2-6 months after hospital discharge due to severe COVID-19. Respiratory symptoms, health-related quality of life, lung function, and the six-minute walk test were assessed. A restrictive ventilatory defect was defined as TLC below the lower limit of normal, as assessed by plethysmography. Chest CT scans performed during hospitalization were scored for the presence and extent of parenchymal abnormalities.

RESULTS

At a mean follow-up of 17.2 ± 5.9 weeks after the diagnosis of COVID-19, 120 patients were assessed. Of those, 23 (19.2%) reported preexisting chronic respiratory diseases and presented with worse lung function and exertional dyspnea at the follow-up visit in comparison with their counterparts. When we excluded the 23 patients with preexisting respiratory disease plus another 2 patients without lung volume measurements, a restrictive ventilatory defect was observed in 42/95 patients (44%). This subgroup of patients (52.4% of whom were male; mean age, 53.9 ± 11.3 years) showed reduced resting gas exchange efficiency (DLCO), increased daily-life dyspnea, increased exertional dyspnea and oxygen desaturation, and reduced health-related quality of life in comparison with those without reduced TLC (50.9% of whom were male; mean age, 58.4 ± 11.3 years). Intensive care need and higher chest CT scores were associated with a subsequent restrictive ventilatory defect.

CONCLUSIONS

The presence of a restrictive ventilatory defect approximately 4 months after severe COVID-19 in patients without prior respiratory comorbidities implies worse clinical outcomes.

Individuals with stroke three months after hospital discharge reported worse quality of life during the COVID-19 pandemic

PURPOSE

To compare quality of life (QOL) of individuals with stroke three months after hospital discharge, using generic and specific QOL measures, before and during the COVID-19 pandemic.

METHODS

Individuals, who were admitted to a public hospital, were recruited and evaluated before (G1) and during (G2) the COVID-19 pandemic. The groups were matched for age, sex, socio-economic status, and levels of stroke severity (National Institutes of Health Stroke Scale) and functional dependence (Modified Barthel Index). After three months of hospital discharge, they were evaluated and compared using generic (Short-form Health Survey 36: SF-36) and specific (Stroke Specific Quality of Life: SSQOL) QOL measures.

RESULTS

Seventy individuals were included (35 in each group). Statistically significant between-group differences were found for both total SF-36 (p=0.008) and SSQOL (p=0.001) scores, indicating that individuals reported worse QOL during the COVID-19 pandemic. Furthermore, G2 also reported worse generic QOL related to the SF-36 domains of physical functioning, bodily pain, general health perception, and emotional role limitations (p < 0.01) and worse specific QOL related to following SSQOL domains: Family roles, mobility, mood, personality, and social roles (p < 0.05). Finally, G2 reported better QOL related to energy and thinking (p < 0.05) SSQOL domains.

CONCLUSION

In general, individuals with stroke, who were evaluated during the COVID-19 pandemic three months after hospital discharge, reported worse perceptions of QOL in several domains of both generic and specific QOL measures.

Translation, adaptation and validation of the Chrononutrition Profile - Questionnaire (CP-Q) in Brazilian Portuguese

Chrononutrition is a science that studies the relationship between mealtimes and sleep/wake habits. However, these behaviors are not evaluated by a single questionnaire. Therefore, this study aimed to translate and culturally adapt the Chrononutrition Profile - Questionnaire (CP-Q) into Portuguese and validate the Brazilian version. The translation and cultural adaptation process consisted of: translation; synthesis of translations; backtranslation; expert committee and pre-test. The validation was performed with 635 participants (32.4 ± 11.2 years) who answered the CPQ-Brazil and Pittsburgh Sleep Quality Index (PSQI); Munich Chronotype Questionnaire (MCTQ); Night Eating questionnaire; Quality of life and health index (SF-36) and 24 h-recall. The participants were mostly female, single, from the northeastern region, a eutrophic profile, and average quality of life score of 55.8 ± 17.9. Moderate to strong correlations were observed in the sleep/wake schedules between CPQ-Brazil, PSQI and MCTQ, both for work/study days and free days. The correlations between largest meal, skipping breakfast, eating window, nocturnal latency, and last eating event with the same variables in the 24 h-recall showed moderate to strong positive correlations. The translation, adaptation, validation and reproducibility of the CP-Q generates a valid and reliable questionnaire to assess the sleep/wake and eating habits in the Brazilian population.

Comparison of Quality of Life in Breast Cancer Survivors with and without Persistent Depressive Symptoms: A 12-Month Follow-Up Study

Although breast cancer treatments reduce mortality, their adverse effects can increase depression which impacts one's quality of life (QoL). Physical activity (PA) seems to improve the QoL of breast cancer survivors (BCS). However, an unanswered question is the influence of PA on the QoL in BCS with depressive symptoms. Thus, we analyzed the influence of PA on the QoL in BCS with persistent depressive symptoms during 12 months of follow-up. The sample included 70 female BCS. Depression and QoL domains (i.e., functional capacity, physical limitations, body pain, general health status, vitality, social and emotional aspects, and mental health) were assessed at baseline and follow-up periods by the Hospital Anxiety and Depression Scale and SF-36, respectively. Habitual PA was assessed by Baecke's questionnaire. Our results indicate a prevalence of 17.1% of depressive symptoms. Non-depressives BCS improved their physical limitations and general health status domains over time, but there were no observed differences in depressive BCS. BCS with persistent depressive symptoms (baseline and follow-up) showed worse QoL scores than non-depressives in all domains, regardless of confounding factors. When adjusted for PA, the difference between BCS depressives and non-depressives lost its significance in the functional capacity domain. In conclusion, habitual PA practice positively influenced the functional capacity domain of the QoL in BCS.

Assessment of short- and long-term functionality and quality of life in patients with post-acute COVID-19 syndrome

BACKGROUND

Although the number of new cases of coronavirus 2019 (COVID-19) has been drastically reduced worldwide, patients who demonstrate long-term symptoms need more attention from health systems, as these symptoms can negatively affect functionality and quality of life.

OBJECTIVE

To evaluate muscle function and quality of life at 3, 6, 9 and 12 months in patients with post-acute COVID-19 syndrome and to assess their associations with general fatigue and lung function.

METHODS

This observational and longitudinal study evaluated patients with post-acute COVID-19 syndrome. Participants were subjected to the following evaluations: Short Form-36; handgrip strength; Functional Assessment of Chronic Illness Therapy-Fatigue scale; and spirometry.

RESULTS

Among the 350 participants who were evaluated in the third month, 74.6%, 61.4% and 45.4% reported general fatigue, dyspnoea and cough, respectively. In the comparisons between the third month and the sixth month, there were significant increases in Functional Assessment of Chronic Illness Therapy-Fatigue scale, pulmonary function and several Short Form-36 domains. In the comparisons between the sixth month and the ninth month, there was a significant increase only in the social functioning domain of the Short Form-36. In the comparisons between the ninth month and the twelfth month, there was an increase only in some Short Form-36 domains. Significant correlations were observed between the Short Form-36 domains with Functional Assessment of Chronic Illness Therapy-Fatigue scale, handgrip strength and pulmonary function.

CONCLUSION

In patients with post-acute COVID-19 syndrome, there was a progressive improvement in quality of life, general fatigue and pulmonary function during the 12 months of follow-up, with this improvement being more pronounced in the first 6 months. There was a relationship between functionality and quality of life in these patients.

Spinal Cord Alignment in Patients with Thoracolumbar Burst Fracture

Objective  To evaluate the spinopelvic alignment in patients with thoracolumbar burst fracture (TBF) without neurological deficit treated nonsurgically and surgically in a tertiary reference trauma hospital. Method  Retrospective cross-sectional study of patients with single level, type A3 and A4 AOSpine TBF only of the thoracolumbar region. Analysis of clinical data, low back pain (visual analogue scale [VAS]), Denis Pain Scale, quality of life (SF-36), sagittal (TC, TLC, LL, SVA) and spinopelvic (IP, PV, SI, PI-LL) radiographic parameters of patients treated surgically and nonsurgically. Results A total of 50 individuals with an average age of 50 years old with a mean follow-up of 109 months (minimum of 19 and maximum of 306 months) were evaluated. There was a significant difference between treatments for the Denis Work Scale ( p  = 0.046) in favor of nonsurgical treatment. There was no significant difference between the treatments for lower back pain VAS and Denis Pain Scale ( p  = 0.468 and p  = 0.623). There was no significant difference between treatments in any of the domains evaluated with the SF-36 ( p  > 0.05). Radiographic parameters were not different between the analyzed groups; however, all radiographic parameters showed significant difference between the population considered asymptomatic, except for pelvic incidence ( p  < 0.005). Conclusions  The spinopelvic alignment was normal in patients with TBF without neurological deficit treated nonsurgically and surgically after a minimum follow-up of 19 months. However, they presented a higher mean pelvic version and discrepancy between lumbar lordosis and pelvic incidence when compared with the reference values of the Brazilian population.

The association between variables of cardiopulmonary exercise test and quality of life in patients with chronic Chagas cardiomyopathy (Insights from the PEACH STUDY)

Studies investigating the association between functional capacity and quality of life (QoL) in individuals with chronic Chagas cardiomyopathy (CCC) usually do not include a gold-standard evaluation of functional capacity, limiting the validity and the interpretation of the results. The present study is a cross-section analysis aiming to evaluate the association between functional capacity (quantified by cardiopulmonary exercise test [CPET]) and QoL in individuals with CCC. QoL was assessed using the SF-36 questionnaire. Sociodemographic, anthropometric, clinical, cardiac function and maximal progressive CPET variables were obtained from PEACH study. Generalized linear models adjusted for age, sex, and left ventricular ejection fraction were performed to evaluate the association between CPET variables and QoL. After adjustments, VO2 peak and VO2 AT were both associated with physical functioning (β = +0.05 and β = +0.05, respectively) and physical component summary (β = +0.03 and β = +0.03, respectively). Double product was associated with physical functioning (β = +0.003), general health perceptions (β = +0.003), physical component summary (β = +0.002), and vitality (β = +0.004). HRR≤12bpm was associated with physical functioning (β = -0.32), role limitations due to physical problems (β = -0.87), bodily pain (β = -0.26), physical component summary (β = -0.21), vitality (β = -0.38), and mental health (β = -0.19). VE/VCO2 slope presented association with all mental scales of SF-36: vitality (β = -0.028), social functioning (β = -0.024), role limitations due to emotional problems (β = -0.06), mental health (β = -0.04), and mental component summary (β = -0.02). The associations between CPET variables and QoL demonstrate the importance of CPET inclusion for a more comprehensive evaluation of individuals with CCC. In this setting, intervention strategies aiming to improve functional capacity may also promote additional benefits on QoL and should be incorporated as a treatment strategy for patients with CCC.

Association between Different Domains of Sedentary Behavior and Health-Related Quality of Life in Adults: A Longitudinal Study

Extended periods of time on screen devices and sitting are the main activities that characterize sedentary behavior (SB), which negatively impacts the quality of life. This negative influence was demonstrated mainly by cross-sectional studies performed in high-income countries in which the effects of screen time on health-related quality of life (HRQoL) is not considered. Thus, we analyzed the association between the different domains of SB (i.e., subdomains of screen time-television, computer, cellphone) and the HRQoL in adults that live in Brazil during two years of follow-up. The sample included 331 adults. Subdomains of screen time (i.e., watching television, using computers, and cellphones) and of HRQoL (i.e., physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health, and current health perception) were assessed by a structured questionnaire and SF-36, respectively. Our results indicate a significant increase in screen time during the two years of follow-up. Linear regression models indicated that although domains of SB were differently associated with HRQoL, in general, screen time was negatively associated with social functioning and positively associated with physical functioning during locomotion and activities of daily living (ADL), role-physical (i.e., physical issues during work and ADLs), and role-emotional (i.e., emotional issues during work and ADLs) after the two-year follow-up. In conclusion, screen time may positively or negatively influence some domains of HRQoL in adults.

Pediatric Liver Transplantation: Caregivers' Quality of Life

PURPOSE

The survival rate of pediatric patients undergoing liver transplantation has increased considerably. Despite this, the period after transplantation is still complex and poses several challenges to the recipient's family, which is responsible for care management. Recently, more attention has been paid to the impact of this complex procedure on the quality of life of caregivers. Hence, this study is aimed at assessing the quality of life of caregivers of patients who have undergone liver transplantation and the aspects that influence it.

METHODS

This was an observational and cross-sectional study. From November 2020 to January 2021, short-form-36 questionnaires and additional questions were given to the main caregivers of children and adolescents who underwent pediatric liver transplantation.

RESULTS

Thirty-eight questionnaires were completed and the results revealed a lower quality of life in comparison to Brazilian standards, primarily in the mental domains (41.8±14.1 vs. 51.1±2.8; p<0.001). It did not show a significant association with socioeconomic or transplant-related factors, but it did show a negative impact on parents' perception of the child's health. Parents who reported worse health status for their children had a lower mental quality of life (44.1±13.8 vs. 33.3±12.6; p<0.05).

CONCLUSION

The caregivers of transplanted children have a lower quality of life than those of the local population. Psychological assistance should be routinely provided to parents for long-term follow-up to mitigate potential negative effects on the transplanted child's care.

Ten sessions of transcranial direct current stimulation for chronic chikungunya arthralgia: study protocol for a randomised clinical trial

INTRODUCTION

The chikungunya virus infection is still an epidemic in Brazil with an incidence of 59.4 cases per 100 000 in the Northeast region. More than 60% of the patients present relapsing and remitting chronic arthralgia with debilitating pain lasting for years. Transcranial direct current stimulation (tDCS) appears promising as a novel neuromodulation approach for pain-related networks to alleviate pain in several pain syndromes. Our objective is to evaluate the effectiveness of tDCS (C3/Fp2 montage) on pain, muscle strength, functionality and quality of life in chronic arthralgia.

METHODS AND ANALYSIS

This protocol is a single-centre, parallel-design, double-blind, randomised, sham-controlled trial. Forty participants will be randomised to either an active or sham tDCS. A total of 10 sessions will be administered over 2 weeks (one per weekday) using a monophasic continuous current with an intensity of 2 mA for 20 min. Participants will be evaluated at baseline, after the 10th session, 2 weeks and 4 weeks after intervention.

PRIMARY OUTCOME

pain assessed using numeric rating scale and algometry.

SECONDARY OUTCOMES

muscle strength, functionality and quality of life. The effects of stimulation will be calculated using a mixed analysis of variance model.

ETHICS AND DISSEMINATION

The study was approved by the ethics committee of the Faculty of Health Sciences of Trairí, Federal University of Rio Grande do Norte (No. 2.413.851) and registered on the Brazilian Registry of Clinical Trials. Study results will be disseminated through presentations at conferences and publications in peer-reviewed journals.

Predictors of the Health-Related Quality of Life (HRQOL) in SF-36 in Knee Osteoarthritis Patients: A Multimodal Model With Moderators and Mediators

Purpose

The study aimed to examine associations between the 36-item short form health survey (SF-36) in clinical and neurophysiological measures to identify its predictors in patients with knee osteoarthritis (KOA) in a rehabilitation program.

Methods

We analyzed data from our cohort study (DEFINE cohort). We analyzed data from our KOA arm, with 107 patients, including clinical assessments, demographic data, pain scales, motor function (Timed Up and Go Test (TUG), 10 meters walk test, and 6-minute walk), balance (BBS), sleepiness (ESS), and Transcranial Magnetic Stimulation (TMS) and Electroencephalography (EEG).

Results

Our results showed 83.19% of patients were female with an average age of 68.6 years and an average number of days of pain was 96 days; around 31.86% were using more than five medications per day. Regarding the multimodal model to explain SF-36, the main variables relevant to the quality of life (QoL) were related to emotional aspects, such as anxiety and depression. Moreover, our study added findings with polymorphism (OPRM1/rs1799971) predicting mental aspects. Cognitive variables were important in predicting the mental health, emotional, and social support dimensions of the SF-36. In the physical domain, pain-related variables predominantly predicted QoL in these relationships. The domain of vitality significantly predicted all dimensions studied, except for mental and general health.

Conclusion

The results help in understanding the aspects that contribute to QoL and are discussed considering the general literature on physical rehabilitation and specific to this clinical group. Furthermore, the statistical methods allowed us to explore and effectively understand the dimensions related to QoL.

Impact of the COVID-19 Pandemic in the Prevalence of Burnout among Residents in Orthopedics

Objective  The primary objective of the present study is to assess the impact of the COVID-19 pandemic on the prevalence of burnout syndrome among residents in orthopedic surgery. As a secondary objective, characteristics associated with the risk of developing the severe form of the syndrome were assessed. Method  In the present cross-sectional study, graduating orthopedic residents were evaluated before and during the COVID-19 pandemic. Medical students formed a control group. The participants answered a sociodemographic questionnaire, the Maslach Burnout Inventory, and the Brazilian validated version of the 36-item short-form health survey questionnaire (SF-36). Fifty-two residents were appraised before the pandemic and 19 during the pandemic. Results  Forty-four (84.6%) residents fulfilled the criteria for burnout syndrome, and the severe form of the syndrome was present in 16 (30.7%). There was no significant change in the evaluated scores after the beginning of the COVID-19 pandemic. There was also no increase in the prevalence of burnout syndrome or of the severe form of the syndrome. A negative correlation was observed between SF-36 items and the development of the severe form of burnout syndrome. Conclusion  The prevalence of burnout syndrome and of the severe form of the disease was very high among residents in orthopedic surgery. The COVID-19 outbreak does not increase burnout in the residents.

Health-related quality of life among radiology technicians in Turkish hospitals: a cross sectional study

BACKGROUND

Health related quality of life (HRQoL), despite its potential bi-directional interaction with occupational risks, has not been extensively addressed among radiology technicians.

OBJECTIVE

To evaluate HRQoL among radiology technicians in relation to sociodemographic and occupational factors.

METHODS

A total of 115 radiology technicians who were employed in three big hospitals located in Istanbul province were included on a voluntary basis in this cross sectional questionnaire-based study conducted between June 2019 and August 2019. The questionnaire form elicited items on socio-demographic characteristics, occupational characteristics and the 36-item Short-form Health Survey (SF-36), respectively.

RESULTS

Overall, 94.8% of technicians confirmed previous training on radiation protection and safety, while 92.2% noted distrust in their knowledge on radiation protection and patient dosage. In addition, 47.8% of technicians noted seldom use of radiation protection measures and 55.7% noted distrust in reliability of radiation exposure measurements. The multiple regression analysis revealed that older age, female gender, working at a university hospital and seldom use of protection significantly predicted poor HRQoL (p = 0.042 to 0.001), while working in interventional radiology and having trust in radiation exposure measurements predicted better HRQoL (p = 0.006 to 0.001) in terms of certain domains.

CONCLUSION

In conclusion, our findings revealed lack of trust in current self-knowledge on radiation protection and safety by majority of radiology technicians and seldom use of radiation protection measures by half of them, despite previously trained on radiation protection and safety. Certain occupational factors and factors related to radiation protection and safety were also amongst the significant determinants of poor HRQoL.

GOOD QUALITY OF LIFE AFTER MORE THAN A DECADE OF LIVING DONOR LIVER TRANSPLANTATION

BACKGROUND

Receptors of living donor liver transplantation (LDLT) have higher rate of postoperative biliary and vascular complications that may reduce posttransplant quality of life (QOL) due to the need of invasive and repetitive treatments.

OBJECTIVE

The purpose of our study is to assess the various aspects of QOL of receptors undergoing LDLT after 10 years of transplantation and to identify potential factors that might be associated with impaired QOL.

METHODS

Data of all patients with more than 10 years of LDLT were retrospectively evaluated. Patients were interviewed through a quality of life questionnaire (SF-36).

RESULTS

From a total of 440 LT performed in 17 years (from September 1991 through December 2008), 78 patients underwent LDLT, of which 27 were alive and 25 answered completely the questionnaire. There were 17 (68%) men and 8 (32%) women, with a mean age of 38.6±18.5 years at the time of transplantation and mean follow up time of 15.1±1.9 years. The average MELD was 16.4±4.9 and the main indication for LT was hepatic cirrhosis caused by hepatitis B virus (32%). When compared to the general po-pulation, LDLT patients had lower mental health score (66.4 vs 74.5, P=0.0093) and higher vitality score (87.8 vs 71.9, P<0.001), functional aspects (94.6 vs 75.5, P=0.002), social aspects (93 vs 83.9, P=0.005), physical aspects (92 vs 77.5, P=0.006), and emotional aspects (97.33 vs 81.7, P<0.001). General health status (73.28 vs 70.2, P=0.074) and pain (78.72 vs 76.7, P=0.672) scores were similar in both groups.

CONCLUSION

It is concluded that the various aspects LDLT recipients' QOF are similar to those of the general population more than a decade after the transplant, except for the mental health domain which is lower.

Self-perceived quality of life of primary antiphospholipid syndrome patients using vitamin K antagonist

PURPOSE

Primary antiphospholipid syndrome (PAPS) is a chronic autoimmune disorder clinically characterized by thromboembolic events or obstetric complications. Prolonged anticoagulation therapy with vitamin K antagonists (VKA) is the treatment of choice for PAPS patients with thrombosis. However, the efficacy of VKA therapy depends on laboratory monitoring, dose adjustment, adequate lifestyle and adherence to treatment. Difficulties with VKA therapy can affect patients' self-perceived health related quality of life (HRQOL). This study aims to evaluate PAPS patients' HRQOL, therapy adherence and knowledge of treatment.

METHODS

A general Medical Outcome Study Short Form-36 (SF-36) and the Duke Anticoagulation Satisfaction Scale (DASS) were used to access APS-patients self-perceived HRQOL. Treatment adherence was measured by the Treatment Measure Adhesion (TMA) - oral anticoagulant version instrument, and knowledge of VKA treatment was measured using the MedTake test.

RESULTS

66 PAPS patients using VKA were assessed. 63% of them were female; the mean age was 41.9 years old, approximately 60% had unprovoked venous thrombosis and one third of the patients had recurrent thrombotic events. The most impacted domain of DASS was "psychological impacts" and the factors associated to anticoagulation related poor HRQOL were: female sex, presence of arterial thrombosis and INR lability. Using the SF-36 instrument, PAPS-patients self-perceived HRQOL was poorer than that of the general Brazilian population and was associated with female sex and presence of cardiovascular risk factors.

CONCLUSION

Despite the high adherence to treatment and knowledge of VKA therapy, self-perceived HRQOL is poor in patients with PAPS and is mainly affected by VKA therapy. Searching for better treatment options is warranted.

Minimally invasive spine surgery: evaluation of clinical and functional outcomes and their correlation with the return to work

BACKGROUND

Intervertebral disc changes are a multi-factorial problem whose main clinical feature is pain. Studies show that when clinical treatments fail, the proposed surgical treatments frequently present unsatisfactory results. Traditional lumbar arthrodesis causes important clinical and functional changes that can result in complications and jeopardize the patients' quality of life.

OBJECTIVES

This study aims to investigate the clinical and functional results of minimally invasive spine surgery in patients with a clinical diagnosis of low-back or sciatic pain and segmental instability, finally correlating these results with the patients' return to work.

METHODS

Patients signed an informed consent form and were clinical and radiographically re-evaluated by independent professionals in the pre- and postoperative periods. Evaluation methods used the Oswestry disability index, as well as visual analog scale and Medical Outcomes Short Form Health Survey (SF-36) scores. We also retrieved epidemiological data, information on work resumption, and bone consolidation evaluations from the medical records.

RESULTS

We evaluated 19 patients who had been operated on 33 levels; visual analog scale and Oswestry disability index scores were initially reduced from 10% to 2% and from 64% to 28%, respectively. SF-36 scores were significantly higher in 5 of the 7 questionnaire scales at the end of the follow-up period. Most patients (68.4%) did not return to work after surgery; the others returned 2 to 67 months after the procedure. All patients received social security benefits after the surgery.

CONCLUSION

Although the procedure presented positive results, it did not result in a satisfactory return-to-work rate. Our results should be analyzed in view of the low educational level and income of the patients, the manual nature of their labor, and the validity of social security benefits.

Health Sciences-Evidence Based Practice Questionnaire (HS-EBP): Normative Data and Differential Profiles in Spanish Osteopathic Professionals

The main goal of this study was to obtain normative data of the scores of the Health-Sciences Evidence Based Practice (HS-EBP) questionnaire, and to analyse evidence-based practice (EBP) among potential clusters of osteopathy professionals in Spain. An online descriptive cross-sectional study has been applied. A total number of 443 Spanish practicing osteopaths answered a survey including the 5 dimensions of the HS-EBP questionnaire and sociodemographic, training, and practice variables using the “LimeSurvey” online platform. Results point out that the median scores for each five HS-EBP questionnaire dimensions were 95.00, 86.00, 78.00, 84.00 and 62.00 considering that the range of possible scores in each of the dimensions was: from 12 to 120 in dimensions 1, 4 and 5; from 14–140 in dimension 2; and from 10–100 in dimension 3. A clustering algorithm extracted 6 different profiles across the five HS-EBP latent dimensions: low scores in all dimensions (cluster 1); low scores in all dimensions but with medium scores in dimension 1 (cluster 2); mixed pattern of scores, low in dimensions 2 and 5 and medium in the rest of the dimensions; medium scores in all dimensions (cluster 4); high scores in all dimensions and low scores in dimension 5 (cluster 5); and high scores in all dimensions (cluster 6). Significant relationship was found among the response patterns in the clusters and: academic degree level, EBP training and training level, and work time invested in healthcare activity, research and teaching activity. These results allow a description of the actual level of EBP and differential profiles of Osteopathy care practice in Spain. Knowledge of normative scores of the HS-EBP questionnaire and identification of different predictors of Spanish osteopaths’ EBP, e.g., academic degree, EBP training and training level, work time invested in healthcare activity, research, and teaching activity, and having a working relationship with an accredited educational centre, enable a comprehensive evaluation of the EBP of osteopathic professionals and can also be useful for developing and implementing formative intervention programs for improving EBP practice in osteopathic practice.

Eight-week equipment-based Pilates exercises positively affects quality of life, and functional capacity in non-active adult women: a randomized controlled trial

BACKGROUND

The Pilates exercises are popular for muscle conditioning among women. However, the effects on conditioning of healthy non-active adult women due to Pilates practicing are not fully explained. The aim of this randomized controlled trial was to assess the effects of equipment-based Pilates exercises on the percentage of body fat, weight, body mass index (BMI), functional capacity, and quality of life of adult healthy women.

METHODS

Seventy-eight non-active women were randomly assigned to 2 groups (Pilates or Control). The Pilates group performed a total of 16 exercise sessions (60 minutes each, performed twice a week for 8 consecutive weeks). The control group was instructed to perform no exercise. Percentage of body fat (DXA scans), weight, BMI, distance covered in the incremental shuttle walk test, maximal oxygen uptake (VO<inf>2max</inf>), and quality of life (SF-36 scores) were analyzed.

RESULTS

There were no significant between-group differences at baseline, but significant group-by-time interaction was observed for Pilates group postintervention. Higher distance covered (P=0.01), VO<inf>2max</inf> (P=0.04), and quality of life (P=0.04) were observed after the intervention compared to the control group. No differences were observed for body composition.

CONCLUSIONS

Two months of equipment-based Pilates training improved functional capacity and quality of life in healthy adult women.

Pilates instructors: prevalence of musculoskeletal pain, associated occupational factors and comparison of quality of life relative to Brazilian reference values

Background

Pain is a public health problem with negative impact on quality of life.

Objective

To analyze the prevalence of musculoskeletal pain and associated occupational factors among Pilates instructors, and to compare their quality of life relative to Brazilian reference values.

Method

A total of 166 Pilates instructors from Rio Grande do Sul, Brazil (consecutive sampling) with degrees in physical education or physical therapy responded the 36-Item Short-Form Health Survey and Work-related Habits Questionnaire. Statistical analysis included calculation of prevalence ratios (Poisson regression) and the simple t-test.

Results

About 62% and 63.3% of the participants reported neck and low back pain, respectively. The prevalence of neck (19%) and low back (16%) pain was higher among the participants who reported to feel always stressed regarding psychological pressure. The prevalence of neck pain was 25% higher among the participants who reported to feel always stressed regarding decision making. The prevalence of neck (15%) and low back (13%) pain was higher among the participants who reported not to perform physical activity. The prevalence of low back pain was 26%, 17% and 24% higher among the participants who reported to always perform physical effort, work standing and use computers, respectively. The scores on seven quality of life domains differed significantly between Pilates instructors and the national average.

Conclusion

Psychological pressure and sedentary lifestyle were associated with neck and low back pain. Physical effort, work standing and computer use were associated with low back pain, and occupational stress with neck pain. Pilates instructors scored lower on seven quality of life domains, the exception being physical functioning.

Health-related quality of life in patients with narcolepsy types 1 and 2 from a Sleep Center in Brazil

INTRODUCTION

Narcolepsy patients have higher prevalence of comorbidities, such as obesity, depression, and pain. Narcolepsy symptoms and concomitant medical conditions can impact the daily activities of patients. The objective of this study is to describe the quality of life in a sample of patients with narcolepsy, and the influence of the nutritional status in health domains.

METHODS

At Unifesp, two groups of 33 patients (narcolepsy types 1 and 2 meeting 2014 criteria, concerning hypocretin-1) and 33 controls without sleepiness, matched by age and sex, filled out the SF-36.

RESULTS

Narcolepsy groups, regardless of their nutritional status, had significantly lower scores in all domains, compared to controls, mainly in Role-physical, Role-emotional, and Energy/Fatigue. Role-physical score was lower in type 1 than in type 2 and controls (37.8±1.0 vs. 50.0±1.2 vs. 85.6±1.6; p<0.0001). Obese with type 2 narcolepsy scored lower than type 1 in physical scales.

CONCLUSION

In a Sleep Center in São Paulo, Brazil, physical and mental health were impaired in narcolepsy types 1 and 2. The first report of the poor health status in Brazilians with narcolepsy type 2 suggests that obesity negatively affects physical domains.

Quality of life of patients with lower limb amputation with prostheses

Abstract Quality of life is often acknowledged as an important outcome of rehabilitation programs for people with amputation. Despite the importance of the subject, the number of studies focusing on the multiplicity of factors influencing this matter is still limited. These assessments are increasingly needed to demonstrate changes related to intervention over time. In order to evaluate the quality of life of patients with lower limb amputation and wearing prostheses, a study was conducted with 49 patients followed in a rehabilitation hospital in the Midwest region of Brazil. A generic instrument (Medical Outcomes Study 36-Item Short-Form Health Survey) for quality of life assessment and Trinity Amputation and Prosthesis Experience Scale-Revised that is specific for people with amputation were used in addition to a functional assessment measure. The results showed that the time since amputation, male gender and below-knee amputations were predictors of a better perception of quality of life and better adjustment to amputation.

HEALTH-RELATED QUALITY OF LIFE OF PATIENTS WITH PERMANENT CARDIAC PACING

ABSTRACT Objective: to assess the health-related quality of life of patients with a permanent cardiac pacemaker. Method: descriptive, observational, cross-sectional study conducted in the arrhythmia outpatient unit of a university hospital located in the interior of São Paulo, Brazil. The consecutive and non-probabilistic sample was composed of both sexes, older than 29 years old, having a pacemaker for at least one month. Those lacking the cognitive condition to answer the questionnaires, as well as those with dyspnea, weakness, or fatigue at the time the instruments were applied, or with an implantable cardioverter defibrillator, were excluded. The generic instrument Medical Outcomes Study 36 - Item Short-Form Health Survey, composed of 36 questions distributed into eight domains along with the specific instrument Assessment of Quality of Life and Related Events, composed of 20 questions distributed into three domains, were used to assess health-related quality of life. Results: 88 patients participated; most were men, had a partner, and were aged 64.3 (±13) years old on average. The domains from the Medical Outcomes Study 36 that obtained the highest means, that is, were the best-rated, were Social Functioning (78.1; ±26.8) and Emotional Well-Being (68.2; ±23.9), while the lowest means were obtained by Physical Health (48.2; ±41.4) and Physical Functioning (58.5; ±27.9). In regard to the Assessment of Quality of Life and Related Events, the Arrhythmia domain had the highest mean and best quality of life (78.2; ±20.7), while the lowest mean was Dyspnea (71.1; ±26.8). Conclusion: the patients gave the highest health-related quality of life ratings in regard to mental domains and the lowest ratings for the physical domains.

Impact of surgery on pain, disability, and quality of life of patients with degenerative lumbar disease: Brazilian data

OBJECTIVE

To study the impact of surgery on pain, disability, quality of life, and patient satisfaction in a sample of patients with Degenerative Lumbar Disease (DLD).

METHODS

Retrospective analysis of prospectively collected data. Comparison between pre and postoperative (6 - 12 months) ODI and SF-36, plus postoperative Patient Satisfaction Index.

RESULTS

From a total of 216 patients included, improvement was observed in average scores of pain (201.2%), disability (39.7%), physical quality of life (42%), and mental quality of life (37.8%). Among these patients, 57.7% reached or surpassed the minimal clinically important difference (MCID) for ODI, 57.7% for the SF-36 pain component, 59.7% for the SF-36 physical component summary, and 50.5% achieved or surpassed the MCID for the SF-36 mental component summary.

CONCLUSIONS

Surgery produced a significantly positive impact on pain, disability, and quality of life of patients. Overall, 82.5% of the patients were satisfied.

Validity and reliability of the 36-Item Short Form Health Survey questionnaire version 2 among people living with HIV in Brazil

Background

The 36-Item Short Form Health Survey questionnaire (SF-36) is a widely used instrument for evaluating health-related quality-of-life (HRQoL). The psychometric validation of the SF-36 version 2.0 (SF-36v2) in HIV-infected patients had not yet conducted in Brazil.

Aim

To test data quality, reliability and validity of the SF-36v2 as a measure of HRQoL among Brazilian individuals living with HIV.

Methods

A cross-sectional study included 393 HIV-infected patients in whom HRQoL was assessed by using the SF-36v2 questionnaire. Demographic characteristics, socioeconomic status and clinical data were also collected. The SF-36 version 1 translated into Brazilian-Portuguese was adapted and introduced version 2 improvements according to the instrument developers. SPSS version 21 was used for data analyses. Confirmatory factor analysis (CFA) and structural equation modelling were performed using AMOS SPSS version 18. T-test for independent samples was used to compare differences between mean levels of HRQoL components in different groups. Linear multiple regression techniques were used to analyze the relationship between Physical Component Summary (PCS), Mental Component Summary (MCS) and independent variables.

Results

We performed the CFA and tested the hypothetical measurement model. We included five parameters to improve the adherence of data to the model. All indicators met the requirement suggested by specialized literature (χ2 (gl): 980.7 (527); CFI: 0.949; GFI: 0.873; TLI: 0.943; RMSEA: 0.047; 90% IC: 0.042-0.051). Multiple regression analyses revealed that depression (p = 0.001), family income (p = 0.007), sex (p = 0.001) and age (p< 0.021) were associated with MCS. Comorbidities (p = 0.001), health self-perception (p = 0.001), age (p = 0.001), and sex (p = 0.025) were associated with PCS.

Conclusions

A consistent validation of the SF-36v2 in Brazilian HIV patients were shown. Further studies with SF-36v2 psychometric analyses would be required in other populations to establish Brazilian normative data.

Do Cleft Lip and Palate Types Affect Health-Related Quality of Life of Adolescents?

The adolescent with oral cleft must deal with the process of body changing and the psychological implications caused by morphological, functional, and esthetic impairments of the cleft itself. This study aimed to evaluate whether the cleft lip and palate types affects health-related quality of life of adolescents through Short-form Health Survey (SF-36) questionnaire. Fifty-seven adolescents (29 males and 28 females; mean age 15 years and 11 months ± 1 year and 2 months) were divided into 2 groups: Group 1-single cleft-unilateral or bilateral CL or CP; Group 2-complex cleft-unilateral or bilateral cleft lip and palate. The participants filled in SF-36 questionnaire to verify their functional, physical, and mental well-being profile. Spearman test assessed SF-36 scores correlation with age. Mann-Whitney U test verified the differences between genders and cleft types. Linear regression models were used to analyze confounding factors (age and gender). P was set at <0.05. The different SF-36 domains weakly correlated with age, ranging from -0.07 (P = 0.60) for the social aspects and 0.31 (P = 0.02) for general health. Females had statistically lower SF-36 scores than males in the domains Bodily pain (P = 0.02), Vitality (P < 0.001), and Mental Health (P < 0.001). G1 showed lower scores in the domains Limitations due to Emotional Problems (P = 0.008) and Mental Health (P = 0.036). However, when the confounding factors (age and gender) were analyzed, the oral cleft type did not affect health-related quality of life (P > 0.05). Considering the age and gender, the cleft lip and palate types did not affect the health-related quality of life of adolescents.

Emotional problems and health-related quality of life: population-based study

PURPOSE

The aim of the present study was to evaluate the influence of emotional problems on health-related quality of life (HRQoL) according to the type of emotional problem, degree of limitation, and perceived control of the problem with treatment.

METHOD

A population-based cross-sectional study with probabilistic stratified cluster sampling was conducted in 2014 and 2015 in the city of Campinas, Brazil. A total of 2145 individuals aged 18 years or older participated in the study. HRQoL was evaluated using the SF-36^® questionnaire. The dependent variables were the score of the eight scales of the SF-36^®. The independent variables were self-perceived emotional problems, type of emotional problem (according to ICD 10), degree of limitation, and perceived control of the problem with treatment. Mean scores were calculated and regression coefficients were adjusted for sex, age, number of health problems, and chronic diseases using multiple linear regression analysis.

RESULTS

The prevalence of emotional problems was 32.7%. Among the individuals with a problem, the mean SF-36^® scores were lower on all domains. Regarding the type of emotional problem, a complaint of depression exerted a stronger negative impact on HRQoL scores than anxiety. Moreover, a greater degree of limitation caused by the problem led to lower mean SF-36^® scores. The negative impact on HRQoL was substantially greater among those who did not have the problem under control.

CONCLUSION

In conclusion, the findings underscore the importance of the prevention and control of emotional problems with the aim of reducing the impact on HRQoL.

Functionality and quality of life of patients with unilateral lymphedema of a lower limb: a cross-sectional study

Background

Lymphedema of the lower limbs is a chronic disease caused by damage to the lymphatic system that influences people's mobility, functionality, and quality of life. Questionnaires and physical test are very practical, easy to apply, and low cost methods that provide important data for evaluation of these patients.

Objectives

To evaluate the influence of unilateral lower limb lymphedema on functionality and quality of life, correlating 3 assessment tools.

Methods

This was a descriptive study investigating 25 patients of both sexes with unilateral lymphedema in a lower limb. Limb volume was assessed using circumferential tape measurements, the Medical Outcomes Study Short Form-36 Health Survey (SF-36) was used to assess quality of life, the Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL) was used to assess physical, mental, and social skills related to lymphedema, and the Timed Up and Go (TUG) test was used for functional assessment.

Results

Lymphedema was present throughout the affected lower limb of participants. The domains most affected by lymphedema were physical aspects (25.0 ± 31.4) and emotional aspects (36.0 ± 42.9) from the SF-36 and the mobility domain (6.0 ± 2.6) from the Lymph -ICF-LL. Patients performed the TUG in 9.88 ± 1.98 seconds. The TUG was correlated with the questionnaires and the questionnaires were correlated with each other.

Conclusions

People with unilateral lower limb lymphedema exhibited negative impacts on quality of life and functionality, as evaluated by questionnaires, which were correlated with each other. TUG performance was within normal limits, but results correlated with the questionnaires used.

Muscle dysfunction is associated with poorer health-related quality of life in adults with sickle cell anaemia

BACKGROUND

It is known that episodes of microvascular obstruction and oxidative stress in sickle cell anaemia (SCA) can damage muscle tissue. As a consequence, deterioration in muscle function may potentially contribute to poor health-related quality of life (HRQoL) in subjects with SCA, particularly those who do not use long-term treatment.

OBJECTIVES

To evaluate muscle function in adults with SCA, to study the correlations between muscle function and HRQoL and to analyse the impact of hydroxyurea treatment.

METHODS

Twenty-two adults with SCA and 20 matched controls were subjected to Short Form-36 (SF-36), respiratory muscle strength measurement, isometric hand grip strength (iHGS) measurement and knee isokinetic dynamometry.

RESULTS

In relation to their healthy peers, adults with SCA had lower SF-36 scores, respiratory muscle strength and iHGS. Regarding the isokinetic test, adults with SCA showed lower values, especially in the variables measured in flexion and with an angular velocity of 240∘/s. There was a significant correlation between the peak torque (PT) at 240∘/s and the physical component summary (SF-36PCS) in both extension (r= 0.77; p< 0.001) and flexion (r= 0.82; p< 0.001). Significant correlations were also observed between the agonist/antagonist ratio at 240∘/s and the SF-36PCS (r= 0.50; p< 0.001). The use of hydroxyurea led to higher scores on the SF-36 and higher values in knee isokinetic dynamometry.

CONCLUSIONS

Adults with SCA have muscle dysfunction, especially with regard to endurance of the knee flexor muscles. In these patients, there is a significant association between muscle function and HRQoL. Moreover, the use of hydroxyurea is associated with better HRQoL and less muscle dysfunction.

Health-related quality of life in Switzerland: normative data for the SF-36v2 questionnaire

Purpose

Health-related quality of life (HRQOL) is an important concept to describe well-being of the general population and persons with diseases. The short form-36 (SF-36) is a widely used questionnaire assessing self-reported HRQOL in eight health domains. The aims of this study were to provide normative data for the SF-36 version 2 (SF-36v2) for all language regions in Switzerland and weighting coefficients to calculate two summary measures for physical and mental health.

Methods

A random representative (regarding age, sex, and language region) sample of people living in Switzerland aged 18–75 years in 2015 was eligible for our questionnaire survey. We calculated the eight health domain subscales for different subsamples based on sociodemographic characteristics. Two summary measures for physical and mental health were derived using data-based factor score coefficients and calculated for the subsamples.

Results

A total of 1209 persons completed the SF-36v2 (mean age 48.7 years, 58.1% women). The SF-36v2 was valid and reliable in Switzerland. Physical health was better in men (p = 0.012) and younger persons (p < 0.001). Mental health was better in men (p < 0.001) and older persons (p < 0.001). Regarding regional differences, we found better physical (p = 0.002) and mental (p < 0.001) health in German speaking persons compared to French and Italian speaking persons.

Conclusions

This paper presents the first SF-36v2 normative data for Switzerland, which are based on a recent study in a representative sample. Our normative data and weighting coefficients will enable future studies to compare HRQOL assessed by the SF-36 in healthy and diseased persons to a representative Swiss sample.

The combined polymorphisms of interleukin-6-174GG genotype and interleukin-10 ATA haplotype are associated with a poor quality of life in patients with chronic hepatitis C

PURPOSE

Chronic hepatitis C (CHC) is associated with a decreased health-related quality of life (HRQOL). More recent studies have pointed toward a genetic basis of patient-reported quality of life outcomes. Taking into account that the influence of single-nucleotide polymorphisms (SNPs) on the HRQOL of CHC patients has not been studied, we investigated the combined IL10-1082G/A, - 819C/T, and - 592C/A SNPs, and IL6-174G/C SNP. We also evaluated the association between demographic, clinical, psychiatric, virological, and genetic variables with domains and summaries of HRQOL in CHC patients.

METHODS

132 consecutive CHC patients and 98 controls underwent psychiatric evaluation by using the Mini International Neuropsychiatric Interview. HRQOL was assessed by a generic questionnaire, the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), and by the specific Liver Disease Quality of Life Questionnaire (LDQOL). IL6 and IL10 polymorphisms were evaluated by Taqman SNP genotyping assay. Multivariate analysis was used to evaluate the associations.

RESULTS

Major depressive disorder was associated with lower SF-36 and LDQOL scores in seven and ten domains, respectively. Diabetes and hypertension were also associated with reduced HRQOL. CHC patients carrying the combination of IL10 ATA haplotype/IL6-GG genotype had lower scores in the SF-36-physical functioning domain, and reduced scores in the LDQOL effects of liver disease on activities of daily living, quality of social interaction, and sexual function domains than the non-carriers of the combined haplotype/genotype.

CONCLUSION

This is the first study to demonstrate that combined IL6 high-producer GG genotype and IL10 low-producer ATA haplotype is associated with poorer HRQOL in CHC patients.

Metabolic syndrome and psoriatic arthritis among patients with psoriasis vulgaris: Quality of life and prevalence

Interest has increased in comorbidities associated with psoriasis and their effects on health-related quality of life (HRQoL). This study aimed to evaluate the prevalence of metabolic syndrome (MetS) and psoriatic arthritis (PsA) and to investigate HRQoL and the prevalence of hypertension, type 2 diabetes mellitus (T2DM), obesity and dyslipidemia. In a cross-sectional design, patients diagnosed with plaque psoriasis answered an interview and standardized questionnaires (Dermatology Life Quality Index questionnaire [DLQI], 36-Item Short Form Health Survey [SF-36] and EuroQol Five-Dimension Questionnaire Three-Level version [EQ-5D-3L]). Physical examination and several tests to assess desired outcomes were performed by a dermatologist and a rheumatologist during three visits. The prevalence of MetS and PsA was 50.0% and 41.8%, respectively. Dyslipidemia was the most prevalent (74.5%) secondary comorbidity, followed by hypertension (61.8%), obesity (52.5%) and T2DM (30.9%). The mean (standard deviation) DLQI score was 6.5 (6.9), and mean physical and mental SF-36 measures were 45.2 (10.4) and 45.5 (12.3), respectively, and for EQ-5D-3L, mean utility index and EQ-VAS scores were 0.68 (0.27) and 72.7 (19.7), respectively. PsA and MetS are important comorbidities; a reduced HRQoL is noted among plaque psoriasis patients with these comorbidities, emphasizing the relevance of diagnosis and treatment beyond the care of skin lesions.

Exercise training improves quality of life in women with subclinical hypothyroidism: a randomized clinical trial

OBJECTIVE

The aim was to evaluate the quality of life (HRQoL) in women with subclinical hypothyroidism (sHT) after 16 weeks of endurance training.

SUBJECTS AND METHODS

In the first phase, a cross-sectional study was conducted in which 22 women with sHT (median age: 41.5 (interquartile range: 175) years, body mass index: 26.2 (8.7) kg/m2, thyroid stimulating hormone > 4.94 mIU/L and free thyroxine between 0.8 and 1.3 ng/dL were compared to a group of 33 euthyroid women concerned to HRQoL. In the second phase, a randomized clinical trial was conducted where only women with sHT were randomly divided into two groups: sHT-Tr (n = 10) - participants that performed an exercise program - and sHT-Sed (n = 10) - controls. Exercise training consisted of 60 minutes of aerobic activities (bike and treadmill), three times a week, for 16 weeks. The HRQoL was assessed by the SF-36 questionnaire in the early and at the end of four months.

RESULTS

Women with sHT had lower scores on functional capacity domain in relation to the euthyroid ones (770 ± 23.0 vs. 88.8 ± 14.6; p = 0.020). The sHT-Tr group improved functional capacity, general health, emotional aspects, mental and physical component of HRQoL after training period, while the sHT-Sed group showed no significant changes.

CONCLUSION

After 16 weeks of aerobic exercise training, there were remarkable improvements in HRQoL in women with sHT.

Quality of life and associated factors in patients with chronic Chagas disease

OBJECTIVES

To evaluate the quality of life (QoL) of patients with Chagas disease (CD) and the association between QoL domains and several clinical, socioeconomic and lifestyle characteristics of this population.

METHODS

Cross-sectional observational study conducted from March 2014 to March 2017 including a total of 361 outpatients followed at Evandro Chagas National Institute of Infectious Disease, Brazil. QoL was assessed using the Portuguese shorter version of the original WHO Quality of Life questionnaire (WHOQOL-BREF). Information about clinical CD presentation, presence of comorbidities, functional class, previous benznidazole treatment, socioeconomic profile and lifestyle was also obtained.

RESULTS

Environment and physical domains presented the worst QoL scores, while the social relationship domain presented the highest score. Multivariate regression analysis demonstrated that variables independently associated with QoL were functional class, sex, clinical presentation of CD, sleep duration, schooling, physical activity level, smoking, income per capita and residents by domicile.

CONCLUSIONS

The low socioeconomic status and the physical limitations imposed by the disease presented an important impact on the QoL reduction among CD patients, especially on environment and physical domains. Strategies to improve QoL among CD patients should be tailored and consider many different variables to maximise improvements not only of patients' physical but also of their mental health.
