Effect of exercise training in patients with chronotropic incompetence and heart failure with preserved ejection fraction: Training-HR study protocol.

BACKGROUND: Chronotropic incompetence (ChI) is linked with diminished exercise capacity in heart failure with preserved ejection fraction (HFpEF). Although exercise training has shown potential for improving functional capacity, the exercise modality associated with greater functional and chronotropic response (ChR) is not well-known. Additionally, how the ChR from different exercise modalities mediates functional improvement remains to be determined. This study aimed to evaluate the effect of three different exercise programs over current guideline recommendations on peak oxygen consumption (peakVO2) in patients with ChI HFpEF phenotype. METHODS AND RESULTS: In this randomized clinical trial, 80 stable symptomatic patients with HFpEF and ChI (NYHA class II-III/IV) are randomized (1:1:1:1) to receive: a) a 12-week program of supervised aerobic training (AT), b) AT and low to moderate-intensity strength training, c)AT and moderate to high-intensity strength training, or d) guideline-based physical activity and exercise recommendations. The primary endpoint is 12-week changes in peakVO2. The secondary endpoints are 12-week changes in ChR, 12-week changes in quality of life, and how ChR changes mediate changes in peakVO2. A mixed-effects model for repeated measures will be used to compare endpoint changes. The mean age is 75.1 ± 7.2 years, and most patients are women (57.5 %) in New York Heart Association functional class II (68.7 %). The mean peakVO2, percent of predicted peakVO2, and ChR are 11.8 ± 2.6 mL/kg/min, 67.2 ± 14.7 %, and 0.39 ± 0.16, respectively. No significant baseline clinical differences between arms are found. CONCLUSIONS: Training-HR will evaluate the effects of different exercise-based therapies on peakVO2, ChR, and quality of life in patients with ChI HFpEF phenotype. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov (NCT05649787).

Cognitive behavioral therapy for insomnia in people with chronic musculoskeletal pain. A systematic review and dose-response meta-analysis.

The aims were (i) to determine the effects of Cognitive behavioral therapy for insomnia (CBT-I) on sleep disturbances, pain intensity and disability in patients with chronic musculoskeletal pain (CMP), and (ii) to determine the dose-response association between CBT-I dose (total minutes) and improvements in sleep disorders, pain intensity and disability in patients with CMP. A comprehensive search was conducted in PubMed/MEDLINE, Web of Science, CINAHL, and SCOPUS until December 17, 2023. Randomized clinical trials (RCTs) using CBT-I without co-interventions in people with CMP and sleep disorders were eligible. Two reviewers independently extracted data and assessed risk of bias and certainty of the evidence. A random effects meta-analysis was applied to determine the effects on the variables of interest. The dose-response association was assessed using a restricted cubic spline model. Eleven RCTs (n = 1801 participants) were included. We found a significant effect in favor of CBT-I for insomnia (SMD: -1.34; 95%CI: -2.12 to -0.56), with a peak effect size at 450 min of CBT-I (-1.65, 95%CI: -1.89 to -1.40). A non-significant effect was found for pain intensity. A meta-analysis of disability was not possible due to the lack of data. This review found benefits of CBT-I for insomnia compared to control interventions, with a large effect size. In addition, it was estimated that a 250-min dose of CBT-I had a large effect on reducing insomnia and that the peak effect was reached at 450 min. These novel findings may guide clinicians in optimizing the use of CBT-I in people with CMP and insomnia.

Acute neuromuscular and perceptual responses to blood flow restriction exercise in adults with severe haemophilia: A pilot study.

INTRODUCTION: No previous studies have implemented a standard blood flow restriction (BFR) training session in people with severe haemophilia (PwH), where this type of training has been contraindicated. AIMS: The purpose of this study was to evaluate the tolerability, adverse events, and neuromuscular and perceptual responses to an acute session of low load (LL) knee extensions with BFR in PwH under prophylaxis. METHODS: Eight PwH performed one LL-BFR session with 40% arterial occlusion pressure (AOP). Perceptual responses and adverse effects were assessed, together with high-density surface electromyography of vastus medialis (VM) and lateralis (VL). RESULTS: Significant normalized root mean square differences were found within each set, but not between sets. Spatial distribution (centroid displacement (p > .05), modified entropy (VM, set two, cycles three and five, p = .032) and coefficient of variation (VM, set two, cycles four and five lower than cycle three (p = .049; p = .036)) showed changes within each set. Median frequency showed a slight increase during cycle four of set four (p = .030). Rate of perceived exertion slightly increased with each set while tolerability slightly decreased in the last set and fear of training with BFR generally decreased after the session. CONCLUSIONS: In PwH, a LL-BFR session at 40% AOP is safe and feasible. Our results suggest that potential muscle impairments may blunt neuromuscular adaptations induced by BFR.

Generalism in species interactions is more the consequence than the cause of ecological success.

Generalism in resource use is commonly considered a critical driver of population success, species distribution and extinction risk. This idea can be questioned as generalism may be a result rather than the cause of species abundance and range size. We tested these contrasting causal hypotheses focusing on host use in three databases encompassing approximately 44,000 mutualistic (hummingbird-plant), commensalistic (lichen-plant) and parasitic (flea-mammal) interactions in 617 ecological communities across the Americas and Eurasia. Across all interaction types, our analyses indicated that range size and abundance influence the probability of encountering hosts and set the arena for species to express generalism potentials or adapt to new hosts. Hence, our findings support the hypothesis that generalism is a consequence of species ecological success. This highlights the importance of ecological opportunity in driving species characteristics considered key for their survival and conservation.

Is the frequency of breakfast consumption associated with life satisfaction in children and adolescents? A cross-sectional study with 154,151 participants from 42 countries.

BACKGROUND: The promotion of daily breakfast consumption and the importance of making appropriate breakfast choices have been underscored as significant public health messages. The aim of this study was to examine the relationship between breakfast frequency and life satisfaction in large and representative samples of school-going children and adolescents aged 10-17 years from 42 different countries. METHODS: This study used information from the 2017/2018 Health Behavior in School-aged Children study, comprising nationally representative samples of children and adolescents aged 10-17 years who were attending school. The total number of participants from the 42 countries included in the study was 155,451 (51.3% girls). The evaluation of breakfast consumption in this study involved a specific question: "How often do you typically have breakfast (more than a glass of milk or fruit juice)?". To measure life satisfaction, a subjective assessment scale was used in the form of a ladder, visually spanning from 0 to 10. On this scale, the topmost point (10) denotes the highest conceivable quality of life, whereas the bottom point (0) represents the worst imaginable quality of life. RESULTS: After adjusting for several covariates, the lowest estimated marginal mean of life satisfaction was identified in those participants who skipped breakfast (mean [M] = 5.6, 95% confidence interval [CI] 5.5 to 5.8). Conversely, the highest estimated marginal mean of life satisfaction was observed in those who had breakfast every day (M = 6.5, 95% CI 6.3 to 6.6). Overall, a nearly linear relationship between higher frequency of breakfast and greater life satisfaction in children and adolescents was identified (p-for-trend < 0.001). In addition, the highest estimated marginal mean of life satisfaction score was identified in those participants from Portugal who had breakfast every day (M = 7.7; 95% CI 6.9 to 8.5 points). Conversely, the lowest estimated marginal mean of life satisfaction was observed in those participants from Romania who no breakfast (M = 3.5; 95% CI 2.6 to 4.4 points). CONCLUSIONS: There is a nearly linear relationship between higher frequency of breakfast and greater life satisfaction in children and adolescents. Considering the potential health advantages associated with breakfast during this critical age phase, these findings imply the necessity for additional global efforts to promote increased breakfast consumption among children and adolescents.

Comorbidity burden and nutritional status are associated with short-term improvement in functional independence and pain intensity after hip fracture surgery in older adults with in-hospital rehabilitation.

PURPOSE: Hip fracture is a common condition among older adults. The aim of this study was to explore the influence of nutritional status and comorbidity burden on changes in functionality, fall risk, and pain intensity one month after hip surgery in older adults with in-hospital rehabilitation. METHODS: Thirty-six hip fracture patients (55.6% female) aged 65 years or older with indication for surgical resolution were recruited. The main outcomes were functional independence (Barthel Index), risk of falls (Downton Falls Risk Index) and pain intensity (Visual Analogue Scale), assessed preoperatively and one month after discharge. Covariates included age, sex, BMI, Charlson Comorbidity Index (CCI) and nutritional status (Mini Nutritional Assessment). For the inferential analysis, a one-way analysis of covariance (ANCOVA) was applied. RESULTS: Significant improvements were observed in functional independence (11.0 points, 95% CI: 1.7 to 20.3), risk of falls (-2.8 points, 95% CI: -4.0 to -1.7) and pain intensity (-2.6 points, 95% CI: -3.4 to -1.9). Among the covariates, a significant interaction was found between the CCI and improvements in functional independence (F=7.03, p=0.010, η2p=0.093), while nutritional status showed a significant interaction with pain reduction (F=5.65, p=0.020, η2p=0.075). CONCLUSION: A lower comorbidity burden was associated with greater postoperative functional independence, while better nutritional status was associated with a greater reduction in postoperative pain intensity.

The Effectiveness of Adding Transvaginal Radiofrequency to Pelvic Floor Muscle Training for 6 Weeks in Women with Stress Urinary Incontinence. A Double-Blind Randomised Controlled Trial.

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the clinically beneficial effect of adding transvaginal monopolar non-ablative radiofrequency (RF) to pelvic floor muscle training (PFMT) on leakage severity, quality of life and urinary incontinence-related symptoms in women with stress urinary incontinence (SUI). METHODS: A double-blind randomised controlled trial was conducted, with a 6-week intervention and a 6-month follow-up. Participants were randomly assigned to the experimental group (PFMT plus RF; n = 18) or the control group (PFMT plus placebo; n = 20). The primary outcome was the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF). Secondary outcomes included the Pelvic Floor Distress Inventory-20 (PFDI-20) and the Pelvic Floor Impact Questionnaire-7 (PFIQ-7), self-efficacy, female sexual function, pelvic floor muscle dynamometry, 1-h pad test and number of SUI episodes per week. Inferential analyses of the data were performed using a two-factor analysis of variance. RESULTS: Both groups achieved a statistically significant improvement in ICIQ-SF over time. However, the differences observed in the experimental group exceeded the minimal clinically important differences by 4 points (MD = -9.4, 95% CI = -12.6 to -6.3), which was not observed in the control group (MD = -3.9, 95% CI = -6.9 to -1.0). This was maintained at the 6-month follow-up with a significant time*group interaction (p < 0.001, ηp2 = 0.150). There was no time*group interaction in the other variables (p > 0.05). Additionally, a significant difference in favour of the experimental group was observed in the 1-h pad test and episodes of SUI per week (p < 0.05). CONCLUSIONS: This study highlights the beneficial effects of adding transvaginal RF to PFMT on the severity and amount of leakage, as well as on the quality of life and urinary incontinence-related symptoms in women with moderate SUI. Future trials are needed to assess the effects of this intervention in women with severe SUI.

Dose-response associations of the American Heart Association's new "Life's essential 8" metrics with all-cause and cardiovascular mortality in a nationally representative sample from the United States.

BACKGROUND: Our aim was to examine the prospective dose-response associations of American Heart Association's (AHA) LIFE's Essential 8 (LE8) score and number of cardiovascular health (CVH) factors with high score with all-cause and cardiovascular disease (CVD) related mortality. METHODS: We pooled 6 consecutive waves of the National Health and Nutrition Examination Survey (NHANES) comprising rounds between 2007 and 2008 and 2017-2018. We calculated hazard ratios (HRs) and conducted restricted cubic splines models to assess the dose-response association of LE8 score and CVH factors with all-cause and CVD mortality. RESULTS: Analyses included 23,531 adults aged 18 years and over (mean [SD] age, 43.6 [16.7] years; 11,979 [51%] female; 8960 [38.1%] non-Hispanic white individuals) with a median follow-up of 7.3 years (IQR 4.3-10.1), corresponding to 168,033 person-years. The dose-response analyses showed a significant inverse curvilinear trend for the association between LE8 score with all-cause and CVD mortality. The optimal risk reduction for all-cause mortality was found at 100 points of the LE8 Score (HR, 0.50; 95% CI, 0.27-0.93) compared to the reference (median LE8 score [62.5 points]). Moreover, the dose-response association between LE8 and CVD mortality also exhibited a significant inverse curvilinear association up to 90 points (HR, 0.41; 95% CI, 0.17-0.99). Optimal levels of LE8 score may be able to avert around 40% of the annual all-cause and CVD deaths among the US adult population. CONCLUSIONS: Best-case scenario of CVH may reduce around 40% of the all-cause and CVD annual mortality among adults in the United States.

Correlation of Self-Efficacy for Pelvic Floor Muscle Exercise with Symptoms of Stress Urinary Incontinence in Women.

INTRODUCTION AND HYPOTHESIS: Self-efficacy for pelvic floor exercises, i.e. confidence in achieving pelvic floor contractions, may predict adherence to treatment. However, there is a paucity of literature investigating the clinical relevance of this outcome. The aim was to determine the relationship between self-efficacy for pelvic floor exercise and symptom severity, pelvic floor distress and impact on quality of life, as well as sociodemographic characteristics and pelvic floor muscle strength in women with stress urinary incontinence (SUI). METHODS: A cross-sectional study was conducted in women with SUI. The Spanish version of the Broome Pelvic Muscle Self-Efficacy Scale was used to assess self-efficacy for pelvic floor exercise. The dependent variables were: urinary incontinence symptoms using the International Consultation on Incontinence Questionnaire, short form (ICIQ-SF), pelvic floor distress symptoms using the Urogenital Distress Inventory-6, impact on quality of life using the Incontinence Impact Questionnaire (IIQ-7), leakage using the 1-h pad test, number of SUI episodes per week and pelvic floor muscle strength. RESULTS: A total of 56 women with a median age of 44.5 years were included. Self-efficacy for pelvic floor exercise correlated negatively and moderately with the ICIQ-SF (r = -0.529; p < 0.001), IIQ-7 (r = -0.442; p = 0.001), 1-h pad test (rs = -0.467; p < 0.001); and number of SUI episodes/week (rs = -0.489; p < 0.001). Correlation with the other outcomes was weak or non-existent. Linear regression with forward selection showed that the ICIQ-SF was the variable most related to self-efficacy (ß: -3.01, 95% CI: -4.03 to -1.69). CONCLUSIONS: These findings highlight the importance of assessing self-efficacy for pelvic floor exercise in the treatment of women with SUI. Future prospective studies are needed to confirm these findings.

Effects of resistance training on muscle strength in adults with haemophilia: A systematic review and meta-analysis.

INTRODUCTION: Although resistance training is frequently prescribed for people with haemophilia (PWH), no previous meta-analyses have quantified the effect of this intervention on muscle strength, nor the implications of the intervention's modality and duration. AIM: (1) To determine the effects of resistance training on muscle strength in adults with haemophilia; (2) To determine the most effective duration and modality among the exercise protocols. METHODS: A systematic search from inception until 28 November 2023 was conducted in PubMed, Embase, Web of Science, CENTRAL and CINAHL databases. We included randomised controlled trials or before-after studies that involved resistance training without other physiotherapy co-interventions. Study selection, data extraction and risk of bias assessment were independently performed by two reviewers. Disagreements were resolved in consultation with a third author. The level of evidence was determined according to the GRADE methodology. RESULTS: Seven studies were included. Measurements of knee extensor strength and elbow extensor strength were included in the meta-analysis. Subgroup analysis showed significant effects for both elastic resistance protocols (SMD: 0.54; 95% CI: 0.02-1.07) and conventional training (isometric and weight-based equipment) (SMD: 0.88; 95% CI: 0.50-1.25), demonstrating small and moderate effect sizes respectively. Additionally, both protocols of duration 5-7 weeks (SMD: 1.16, 95% CI: 0.63-1.69) as well as those of duration ≥8 weeks (SMD: 0.57, 95% CI: 0.20-0.94) showed a significant difference. CONCLUSION: Resistance training is effective in improving muscle strength of the knee and elbow extensors in PWH. Both elastic resistance and conventional training show benefits.

How do the target concepts of pain science education combined with exercise contribute to the effect on pain intensity and disability in patients with chronic spinal pain? A systematic review and meta-analysis with moderator analysis.

The aim of this study was to assess the moderator effect of the target concepts covered in the Pain science education (PSE) sessions, including both the total amount of target concepts and each individual target concept, on changes in pain intensity and disability in patients with chronic spinal pain (CSP). A systematic search of PubMed, Scopus, Embase, Web of Science and CENTRAL was conducted from inception to March 10, 2024. A random effects model was used for meta-regression analysis. A total of 11 studies were included. The total amount of target concepts of PSE showed a significant correlation with changes in pain intensity (k=11; F=4.45; p=0.04; R2=26.07 %). In terms of each target content, only a significant effect on pain intensity was obtained for 'transfer knowledge about pain to an adaptive behavioural change' (z=-2.35, P =0.019, 95 %CI -3.42 to -0.31) and 'reconceptualization of pain' (z=-2.43, P =0.015, 95 %CI -3.70 to -0.39). No significant effect on disability was found. These results may be useful for optimising the effectiveness of PSE programmes.

Clinical mutations in the TERT and TERC genes coding for telomerase components induced oxidative stress, DNA damage at telomeres and cell apoptosis besides decreased telomerase activity.

Telomeres are nucleoprotein structures at the end of chromosomes that maintain their integrity. Mutations in genes coding for proteins involved in telomere protection and elongation produce diseases such as dyskeratosis congenita or idiopathic pulmonary fibrosis known as telomeropathies. These diseases are characterized by premature telomere shortening, increased DNA damage and oxidative stress. Genetic diagnosis of telomeropathy patients has identified mutations in the genes TERT and TERC coding for telomerase components but the functional consequences of many of these mutations still have to be experimentally demonstrated. The activity of twelve TERT and five TERC mutants, five of them identified in Spanish patients, has been analyzed. TERT and TERC mutants were expressed in VA-13 human cells that express low telomerase levels and the activity induced was analyzed. The production of reactive oxygen species, DNA oxidation and TRF2 association at telomeres, DNA damage response and cell apoptosis were determined. Most mutations presented decreased telomerase activity, as compared to wild-type TERT and TERC. In addition, the expression of several TERT and TERC mutants induced oxidative stress, DNA oxidation, DNA damage, decreased recruitment of the shelterin component TRF2 to telomeres and increased apoptosis. These observations might indicate that the increase in DNA damage and oxidative stress observed in cells from telomeropathy patients is dependent on their TERT or TERC mutations. Therefore, analysis of the effect of TERT and TERC mutations of unknown function on DNA damage and oxidative stress could be of great utility to determine the possible pathogenicity of these variants.

Enhanced Muscle Endurance Through Self-regulated Dual-Task Exercises in Elbow Fracture Rehabilitation: A Cross-sectional Study.

OBJECTIVE: The main objective of this study was to investigate the effect of a self-regulated dual task on muscle endurance within a single rehabilitation session in patients recovering from an elbow fracture. DESIGN: This is a cross-sectional study of individuals recovering from elbow fractures ( N = 20). Muscle endurance was tested using elastic bands at Borg's CR10 intensity 3-during four conditions: single-task and dual-task for elbow flexion and extension. RESULTS: The cognitive condition significantly influenced muscle endurance ( P < 0.001), while the type of elbow exercise (flexion or extension) did not show significant differences ( P = 0.592). The perceived difficulty of the tasks showed a significant interaction effect ( P = 0.032). The dual-task condition showed an average increase of about 15 repetitions. A moderate negative correlation was found between the differences in repetitions and the perceived difficulty of the flexion exercise ( r = 0.677, P = 0.001). CONCLUSIONS: Dual-task with self-regulation enhances muscle endurance among patients recovering from an elbow fracture. However, the improvements seem to depend on the perceived difficulty of the cognitive task. Future randomized controlled trials are required to understand the therapeutic implications of dual-tasking.

Psychological factors are associated with pain extent in patients with carpal tunnel syndrome.

INTRODUCTION: Widespread pain may be related to psychosocial aspects in several musculoskeletal conditions, but the literature on carpal tunnel syndrome (CTS) is scarce. OBJECTIVE: To determine the relationship between pain extent and psychological factors (catastrophizing, kinesiophobia, anxiety symptoms, and depression) in people with CTS. METHODS: A cross-sectional study was conducted. The independent variables were: pain intensity, disability (QuickDASH), duration of symptoms, anxiety and depressive symptoms, catastrophizing, and kinesiophobia. The main outcome was: pain extent (% of total area and categories "pain within the median nerve-innervated territory" versus "extra-median nerve pain"). Correlation analysis was performed using Spearman's correlation coefficient. A linear regression model and binary logistic regression (both with forward selection) were performed to determine the main predictors of pain extent. RESULTS: Forty-eight participants were included. A moderate positive correlation was found between catastrophizing (r = 0.455; p = 0.024) and disability (r = 0.448; p = 0.024) with total pain extent area. Regression models indicated that catastrophizing explained 22% of the variance in the pain extent (ß = 0.003; 95% CI: 0.002-0.005), while kinesiophobia was the variable that best explained the distribution of pain in the extra-median territory (R2 Nagelkerke = 0.182). Null or weak correlations were found for the rest of the associations. CONCLUSION: Catastrophizing and kinesiophobia were the main indicators of pain extent in people with CTS. Clinicians are advised to use specific questionnaires to check for the presence of catastrophizing or kinesiophobia in people with CTS and wider pain extension.

Comparative Electromyographic Study of Scapular Stabilizing Muscles During Five Main Rehabilitation Exercises.

OBJECTIVE: The aim of the study is to compare the surface electromyographic amplitude, activation ratio, and onset latency of the main scapular stabilizing muscles between five typical rehabilitative exercises. DESIGN: Twenty-seven healthy participants performed five scapular exercises (wall slide, wall push-up plus, prone horizontal abduction with external rotation, external rotation in side lying, and low row) while simultaneously recording surface electromyographic of serratus anterior, middle trapezius, lower trapezius, and upper trapezius. Surface electromyographic amplitudes, onset latencies, and activation ratios were calculated. RESULTS: Prone horizontal abduction with external rotation showed an excellent upper trapezius/middle trapezius (0.43) and upper trapezius/lower trapezius (0.30) muscle balance with high (>50% maximum voluntary isometric contraction) middle trapezius and lower trapezius amplitudes, a low (<20% maximum voluntary isometric contraction) upper trapezius amplitude, and an early activation of the scapular stabilizing muscles (-474.7 to 89.9 ms) relative to upper trapezius. External rotation in side lying showed excellent upper trapezius/serratus anterior (0.26), upper trapezius/middle trapezius (0.32), and upper trapezius/lower trapezius (0.21) activation ratios and, along with low row and wall slide, showed early activation of the scapular stabilizing muscles (-378.1 to -26.6 ms). CONCLUSIONS: Prone horizontal abduction with external rotation presented optimal scapular neuromuscular control. Although external rotation in side lying, low row, and wall slide did not meet all the criteria associated with optimal scapular neuromuscular control, these exercises could be used in early stages of shoulder rehabilitation because they favor early activation of the scapular stabilizing muscles.

Does the distribution of musculoskeletal pain shape the fate of long-term sick leave? A prospective cohort study with register follow-up.

ABSTRACT: Although multisite pain can markedly reduce work ability, the relevance of the bodily pain distribution as a predictor of long-term sick leave is still unknown. This study aimed to investigate the association between musculoskeletal pain distributions and long-term sick leave in the general working population of Denmark and included 66,177 currently employed wage earners without long-term sick leave during the prior 52 weeks. Participants reported whether they had pain in the lower extremity (hips/knees), upper extremity (neck/shoulders), or the low back. The analysis controlled for age, sex, year of survey reply, educational level, occupational group, psychosocial work factors, body max index, smoking, leisure-time physical activity, and mental health confounders. The results demonstrated that the risk of long-term sick leave increased with the number of pain sites. Compared with no pain, localized pain in any body region increased the risk/hazard by 25% to 29% (HR [95% CI]: 1.29 [1.07-1.54] for pain only in the low back), whereas pain in 2 regions increased the risk by 39% to 44% (HR [95% CI]: 1.41 [1.18-1.69] for pain in the low back + hips/knees). Workers reporting pain in all 3 regions experienced a 72% increased risk (HR [95% CI]: 1.72 [1.55-1.91]). Thus, the number of pain regions seems to matter more than the exact pain location. The spatial extension of musculoskeletal pain in workers functions as a gradient system, where pain spread throughout the body is an independent indicator of the high risk of long-term sick leave.

Effects of exercise-based interventions on inflammatory markers in patients with fibromyalgia: A systematic review and meta-analysis.

OBJECTIVES: The aim of the present review was (1) to determine the effects of exercise based-interventions (EBIs) on pro-inflammatory and anti-inflammatory biomarkers in patients with fibromyalgia (FM), and (2) to determine the most effective type (acute or maintained) and modality (aerobic, resistance, etc.). METHODS: A systematic search was conducted in various electronic databases to identify all the relevant studies: Medline (PubMed), PEDro, EBSCO and Google Scholar. Clinical trials assessing the effects of EBIs in patients with FM were selected. Methodological quality was evaluated by two independent investigators using the Cochrane Risk of Bias Tool. Qualitative analysis was based on the classification of the results into levels of evidence according to GRADE. RESULTS: Eleven studies were included. The meta-analysis showed a statistically significant decrease in proinflammatory biomarkers by EBIs with a large clinical effect in 19 comparisons (SMD: 1.74; 95 % CI: 0.85-2.62; p < 0.05), especially for IL8. The certainty of the evidence was low. The meta-analysis showed no statistically significant increase in anti-inflammatory biomarkers (IL10) by EBIs in 6 comparisons and very low certainty of evidence. Evidence was found for acute and maintained effects of exercise, with aerobic and aquatic exercise modalities showing better improvements than resistance exercise. CONCLUSIONS: EBIs are effective in inducing an immunomodulatory response in FM, characterized by decreased pro-inflammatory signaling. However, there was no evidence of an increase in anti-inflammatory biomarkers. These results should be interpreted with caution due to low certainty of evidence.

The importance of a healthy lifestyle despite chronic pain: Prospective cohort with 11-year register follow-up.

The purpose of the study was to investigate to which extent a healthy lifestyle in female healthcare workers with chronic pain contributes to reducing the risk of disability pension. We conducted a prospective cohort study with an 11-year registry follow-up. Overall, 2386 Danish female healthcare workers with chronic pain completed a questionnaire about work and lifestyle (leisure-time physical activity, smoking, and body mass index (BMI)). Data on disability benefit payments were obtained from the Danish Register for Evaluation of Marginalization. Two models (minimally and fully adjusted for different potential confounders) were tested using the Cox proportional hazards model. During the follow-up period, 17.9% of the healthcare workers obtained disability pension. Low levels of leisure time physical activity (reference: moderate level) increased the risk of disability pension in the minimally (Hazard Ratio: 1.38 (95% CI: 1.14-1.69)) and fully adjusted models (Hazard Ratio: 1.27 (95% CI: 1.04-1.56)). Being highly physically active, as opposed to being moderately active, did not confer additional protection. Additionally, a positive association was observed between smoking and disability pension in the minimally adjusted model (Hazard Ratio: 1.27 (95% CI: 1.05-1.54)). BMI was not an influential factor. In female healthcare workers with chronic pain, at least moderate levels of physical activity is a protective factor for disability pension. Effective promotion strategies should be designed for both workplace and non-workplace settings.

Risk and Preventive Factors for Depressive Symptoms Among Older Chilean Adults During the SARS-CoV-2 Outbreak: A Longitudinal Study.

OBJECTIVE: To specifically examine the multiple factors related to the increase in depressive symptoms during the COVID-19 outbreak in older adults in Chile. METHOD: A longitudinal study was conducted using a dataset from a nationally representative survey cohort of Chilean older adults followed at three time points during the COVID-19 outbreak. The main outcome was depressive symptoms (Patient Health Questionnaire scale). The independent variables included: age, sex, educational level, geographic area, living alone, self-perceived health, self-reported resilience, loneliness, and social isolation. RESULTS: A total of 424 older adults were included. Female sex (ß = 0.95, 95% CI: 0.22 to 1.68) and loneliness (ß = 1.21, 95% CI: 1.05 to 1.37) were the main risk factors for an increase in depressive symptoms in older adults. In contrast, living outside the metropolitan region (ß=-0.70, 95% CI: -1.39 to -0.02), living in company (ß=-0.34, 95% CI:-1.24 to 0.56), having better self-perceived health (ß=-5.04, 95% CI:-6.33 to -3.75) and greater resilience (ß=-0.30, 95% CI: -0.38 to -0.23) were preventive factors. CONCLUSION: These results provide useful evidence to develop mental health prevention or control strategies for older adults. CLINICAL IMPLICATIONS: The findings highlight the importance of a holistic approach to health care for older adults that integrates strategies to address loneliness, foster resilience, and promote an active social life.

Association Between Pain Coping and Symptoms of Anxiety and Depression, and Work Absenteeism in People With Upper Limb Musculoskeletal Disorders: A Systematic Review and Meta-analysis.

OBJECTIVE: To determine the prospective association of pain coping strategies and symptoms of anxiety and depression with work absenteeism in people with upper limb musculoskeletal disorders. DATA SOURCES: A systematic search of PubMed, Web of Science, Embase, Cochrane Library, and Scopus databases was conducted from inception to September 23, 2022. STUDY SELECTION: Prospective observational studies of adults with upper limb musculoskeletal disorders were included. Included studies had to provide data on the association of pain coping strategies (catastrophizing, kinesiophobia, self-efficacy or fear avoidance) or symptoms of anxiety and depression with work absenteeism. DATA EXTRACTION: Study selection, data extraction, and assessment of methodological quality (Newcastle Ottawa Scale) were performed by 2 independent authors. Random-effects models were used for quantitative synthesis. DATA SYNTHESIS: Eighteen studies (n=12,393 participants) were included. Most studies (77.8%) reported at least 1 significant association between 1 or more exposure factors (pain coping strategies or symptoms of anxiety and depression) and work absenteeism. Meta-analyses showed a statistically significant correlation between the exposure factors of catastrophizing (r=0.28, 95% confidence interval [CI]: 0.15 to 0.40; P<.0001) and symptoms of anxiety and depression (r=0.23, 95% CI: 0.10 to 0.34; P=.0003) with work absenteeism. The correlation between self-efficacy and work absenteeism was non-significant (r=0.24, 95% CI: -0.02 to 0.47; P=.0747). CONCLUSIONS: Rehabilitation teams should consider assessing catastrophizing and symptoms of anxiety and depression to identify patients at risk for work absenteeism. Addressing these variables may also be considered in return-to-work programs for individuals with upper limb disorders.
