ABSTRACT
BACKGROUND: Obesity is a complex chronic disease associated with several adverse health outcomes that increase mortality risk. Physical activity (PA) is recommended for the prevention and treatment of obesity and is related to a decreased risk of cardiovascular disease, cancer and all-cause mortality. This systematic review and meta-analysis estimates the effect of PA levels on mortality (cardiovascular, cancer and all-cause mortality) in adults with obesity. METHODS: A systematic search was conducted in MEDLINE, Embase, Web of Science and SPORTDiscus from inception to June 2024. Prospective cohort studies that explored the association between PA and mortality in adults with obesity (according to their body mass index, ≥ 30 kg/m2) aged ≥ 18 years were included. Our main outcomes were all-cause mortality, and cardiovascular, and cancer mortality reported in primary studies by hazard ratios or relative risk, which were pooled for the meta-analysis when at least two studies reported the effect estimate for the same outcome. The PRISMA recommendations and the MOOSE guidelines were followed. The reported mortality risk estimates comparing insufficiently active versus active (moderate to very active) adults with obesity were pooled using the DerSimonian and Laird random-effects model. RESULTS: A total of 9 prospective cohort studies involving 199,425 adults with obesity (age range: 35-85 years) were included, of which 59,873 were insufficiently active and 84,328 were active. Active individuals had a 21% lower risk of all-cause mortality (HR: 0.79, 95%CI: 0.74 to 0.84; I2 = 38.2%), and a 24% lower risk of cardiovascular mortality (HR: 0.76, 95%CI: 0.66 to 0.87; I2 = 0.0%) than insufficiently active individuals. The HR for cancer mortality was 0.91 (95%CI: 0.80 to 1.02; I2 = 0.0%), and although this was mostly consistent with a benefit, it was based on only two studies. CONCLUSION: Our data support that moderate to high levels of PA are associated with a 21% lower risk of all-cause and 24% cardiovascular disease mortality in adults with obesity. Although data from the only two published studies seem to indicate a protective effect of PA on cancer risk, the estimates are not statistically significant.

PURPOSE: Our objective was to synthesize and determine whether there are sex differences in physical function following exercise interventions in older adults. MATERIALS AND METHODS: A systematic search was conducted in four databases from inception to July 8th, 2023 searching for prospective trials that conducted exercise interventions in older adults and results for physical function were reported by sex. Pooled standardized mean differences (SMDs) with their 95% confidence intervals (CIs) were estimated using a randomeffects method. The Sidik-Jonkman estimator was used to calculate the variance of heterogeneity (I²). RESULTS: A total of 19 studies involving 20,133 older adults (mean age ≥60 years, 33.7% female) were included. After exercise interventions, males reported significantly greater pre-post changes compared to females for upper body strength (SMD=-0.40, 95% CI: -0.71 to -0.09; I²=75.6%; n=8), lower body strength (SMD=-0.32, 95% CI: -0.55 to -0.10; I²=52.0%; n=11), and cardiorespiratory fitness (SMD=-0.29, 95% CI: -0.48 to -0.10; I²=89.1%; n=12). Conversely, the pooled SMDs showed a significant effect favoring females for motor fitness (SMD=0.21, 95% CI: 0.03 to 0.39; I²=0%; n=7). Limited and inconsistent results were observed for flexibility. CONCLUSIONS: Our study suggests the existence of sex-related differences on physical function after an exercise intervention in the older population.
ABSTRACT
Vitamin D supplementation has been considered a possible treatment to reduce the risk of disease activity and progression in people with multiple sclerosis (MS). However, its effect on disease symptoms remains unclear. The aim of this meta-analysis was to conduct a systematic review to assess the effect of vitamin D on fatigue in this population. The systematic review was conducted using the MEDLINE, Cochrane Library, Embase and Web of Science databases from inception to May 2023. Randomized controlled trials (RCTs) reporting pre-post changes in fatigue after vitamin D supplementation were included. Pooled effect sizes and 95% confidence intervals (95% CIs) were calculated by applying a random effects model with Stata/SE (Version 16.0; StataCorp., College Station, TX, USA). The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. A total of five studies with 345 individuals (271 females; age range: 25.4-41.1 years) were included. A significant reduction in fatigue was perceived when vitamin D supplementation was compared with a control group: -0.18 (95% CI: -0.36 to -0.01; I2 = 0%). Thus, our findings show that the therapeutic use of vitamin D on fatigue in people with MS could be considered. Nevertheless, due to the lack of agreement on the dose to be applied, it is recommended to use it under medical prescription.

BACKGROUND AND AIMS: Lean mass is considered the best predictor of bone mass, as it is an excellent marker of bone mechanical stimulation, and changes in lean mass are highly correlated with bone outcomes in young adults. The aim of this study was to use cluster analysis to examine phenotype categories of body composition assessed by lean and fat mass in young adults and to assess how these body composition categories are associated with bone health outcomes. METHODS: Cluster cross-sectional analyses of data from 719 young adults (526 women) aged 18-30 years from Cuenca and Toledo, Spain, were conducted. Lean mass index (lean mass (kg)/height (m)2), fat mass index (fat mass (kg)/height (m)2), bone mineral content (BMC) and areal bone mineral density (aBMD) were assessed by dual-energy X-ray absorptiometry. RESULTS: A cluster analysis of lean mass and fat mass index z scores resulted in a classification of a five-category cluster solution that could be interpreted according to the body composition phenotypes of individuals as follows: high adiposity-high lean mass (n = 98), average adiposity-high lean mass (n = 113), high adiposity-average lean mass (n = 213), low adiposity-average lean mass (n = 142), and average adiposity-low lean mass (n = 153). ANCOVA models showed that individuals in clusters with a higher lean mass had significantly better bone health (z score: 0.764, se: 0.090) than their peers in other cluster categories (z score: -0.529, se: 0.074) after controlling for sex, age, and cardiorespiratory fitness (p < 0.05). Additionally, subjects belonging to the categories with a similar average lean mass index but with high or low-adiposity levels (z score: 0.289, se: 0.111; z score: 0.086, se: 0.076) showed better bone outcomes when the fat mass index was higher (p < 0.05). CONCLUSIONS: This study confirms the validity of a body composition model using a cluster analysis to classify young adults according to their lean mass and fat mass indices. In addition, this model reinforces the main role of lean mass on bone health in this population and that in phenotypes with high-average lean mass, factors associated with fat mass may also have a positive effect on bone status.

BACKGROUND: It is assumed that people with multiple sclerosis (MS) who participate in programs of physical exercise improve their physical fitness. OBJECTIVE: The aim of this network meta-analysis (NMA) was to analyze the effect of different types of exercise on muscular fitness and cardiorespiratory fitness (CRF) among people with MS and to determine the best type of exercise according to disease severity. METHODS: MEDLINE, the Physiotherapy Evidence Database, the Cochrane Library, SPORTDiscus, Scopus, and Web of Science were searched from inception to April 2022 to identify randomized controlled trials (RCTs) concerning the effect of physical exercise on fitness in people with MS. We ranked the types of physical exercise by calculating the surface under the cumulative ranking (SUCRA). RESULTS: We included 72 RCTs involving 2543 MS patients in this NMA. A ranking of five types of physical exercise (aerobic, resistance, combined [aerobic and resistance], sensorimotor training, and mind-body exercises) was achieved. Combined and resistance training had the highest effect sizes (0.94, 95% CI 0.47, 1.41, and 0.93, 95% CI 0.57, 1.29, respectively) and the highest SUCRA (86.2% and 87.0%, respectively) for muscular fitness. The highest effect size (0.66, 95% CI 0.34, 0.99) and SUCRA (86.9%) for CRF was for aerobic exercise. CONCLUSIONS: Combined and resistance training seem to be the most effective exercises to improve muscular fitness and aerobic exercise for CRF in people with MS.

BACKGROUND: Hypermobile Ehlers-Danlos Syndrome (hEDS) is the most common type of EDS. Apart from joint symptoms, people with hEDS have systemic manifestations as a chronic modification of the breathing pattern (functional respiratory complaints (FRCs)) and mental disorders. However, the prevalence of FRCs, and its relationship with mental disorders, have not yet been estimated for this population. OBJECTIVES: To assess the FRCs, central sensitization, disease perception, depression, and anxiety in people with hEDS from Belgium; and to identify the clustering of FRCs and determine any association with the characteristics assessed for this sample. METHODS: This cross-sectional study assessed socio-demographic characteristics, Nijmegen questionnaire (NQ), Central Sensitization Inventory (CSI), Brief Illness Perception Questionnaire, and the Hospital Anxiety and Depression Scale (HADS) in people with hEDS from Belgium. A two-step cluster analysis was performed to identify clusters according to NQ, and to understand how the other questionnaires are grouped among these clusters. RESULTS: The Spearman correlation coefficients showed that all the outcomes were significantly and positively correlated with each other (p<0.05). Furthermore, 84.9% of the sample had symptoms suggestive of FRCs, and 54.3% had probable anxiety. Three clusters were grouped (no FRCs, mild FRCs, and severe FRCs), with NQ, HADS-D and CSI-part A being the variables that contributed the most. People from cluster of severe FRCs got the worst scores for all the questionnaires. CONCLUSION: FRCs, central sensitization, depression, and anxiety are prevalent comorbidities in people with hEDS. Moreover, those people with FRCs had worse results in the investigated parameters, with depression being the variable that contributed the most to the clusters of FRCs. Consequently, investigating mechanisms for these co-occurring symptom profiles may improve our understanding of pathogenesis and indicate new management strategies to alleviate these symptoms and lead to the development of more effective care for persons with hEDS.

OBJECTIVES: The two aims of this systematic review and meta-analysis were to (1) analyze the effect of exercise on chemotherapy-induced peripheral neuropathy (CIPN) severity and (2) determine the best type of exercise for the management of CIPN. METHODS: We systematically searched the MEDLINE, WOS, Sportdiscus, Scopus, and Cochrane databases from inception to December 2020 for experimental studies addressing the effect of exercise on CIPN severity, as measured by symptom severity (SSS) and peripheral deep sensitivity (PDS). The DerSimonian and Laird method was used to compute pooled estimates of the standardized mean differences (SMDs) and its respective 95% confidence intervals (CIs). Subgroup analyses were performed based on the types of exercise and the frequency and length of the interventions. RESULTS: Thirteen studies were included in this meta-analysis. In the analyses comparing exercise interventions versus controls, there was an improvement in the SSS (SMD = -0.21; 95% CI: -0.40 to -0.01; %change: -20.34%) and the PDS (SMD = 0.49; 95% CI: 0.06 to 0.91; %change: 31.64%) in favor of the intervention group. In the pre-post analyses, there was an improvement in the SSS (SMD = -0.72; 95% CI: -1.10 to -0.34; %change: -15.65%) and the PDS (SMD = 0.47; 95% CI: 0.15 to 0.79; %change:18.98%). CONCLUSIONS: This meta-analysis provides an overview of the evidence supporting exercise as a suitable intervention to reduce the severity of CIPN by reducing the severity of the symptoms and the peripheral deep sensitivity among patients with cancer or cancer survivors. Furthermore, sensoriomotor training and mind-body exercises appear to be more effective in reducing symptom severity, and active nerve-specific exercises and mind-body exercises seem to be more effective in improving peripheral deep sensitivity.

BACKGROUND: The positive influence of most types of exercise has been reported repeatedly, but what the most effective exercise approaches are for improving health-related quality of life (HRQoL) in people with cancer remains unknown. The aim of this systematic review and network meta-analysis was to synthesize the evidence from intervention studies to assess the effects of different types of exercise on HRQoL during and after cancer treatment. METHODS: MEDLINE, SPORTDiscus, the Cochrane Library, Web of Science, and Scopus were searched for randomized controlled trials aimed at testing the effects of exercise interventions meant to improve HRQoL in people with cancer. Separate analyses were conducted for HRQoL as measured by general and cancer-specific questionnaires. We also evaluated whether the effects of exercise were different during and after cancer treatment in both the physical and mental HRQoL domains. RESULTS: In total, 93 studies involving 7435 people with cancer were included. Network effect size estimates comparing exercise intervention vs. usual care were significant for combined exercise (0.35, 95% confidence interval (95%CI): 0.14-0.56) for HRQoL as measured by general questionnaires, and for combined (0.31, 95%CI: 0.13-0.48), mind-body exercise (0.54, 95%CI: 0.18-0.89), and walking (0.39, 95%CI: 0.04-0.74) for HRQoL as measured by cancer-specific questionnaires. CONCLUSION: Exercise programs combining aerobic and resistance training can be recommended to improve HRQoL during and after cancer treatment. The scarcity and heterogeneity of these studies prevents us from making recommendations about other exercise modalities due to insufficient evidence.

The aim of this study was to compare the clinical effectiveness and complications of different treatment modalities for elderly patients with distal radius fracture (DRF). METHODS: We performed a network meta-analysis (NMA) of randomized clinical trials (RCTs). Eight databases were searched. The eligibility criteria for selecting studies were RCTs that compared different treatment modalities (surgical or nonoperative) in patients older than 60 years with displaced or unstable intra-articular and/or extra-articular DRFs. RESULTS: Twenty-three RCTs met the eligibility criteria (2020 patients). For indirect comparisons, the main findings of the NMA were in volar locking plate (VLP) versus cast immobilization, with the mean differences for the patient-rated wrist evaluation (PRWE) questionnaire at -4.45 points (p < 0.05) and grip strength at 6.11% (p < 0.05). Additionally, VLP showed a lower risk ratio (RR) of minor complications than dorsal plate fixation (RR: 0.02) and bridging external fixation (RR: 0.25). Conversely, VLP and dorsal plate fixation showed higher rates of major complications. CONCLUSIONS: Compared with other treatment modalities, VLP showed statistically significant differences for some functional outcomes; however, most differences were not clinically relevant. For complications, although most differences were not statistically significant, VLP was the treatment modality that reported the lowest rate of minor and overall complications but also showed one of the highest rates of major complications in these patients.

BACKGROUND: There is evidence for the positive effects of neurodynamic techniques in some peripheral entrapment neuropathies, but the rationale for these effects has not been validated. We aimed to estimate the direct effect of neurodynamic techniques on the dispersion of artificially induced intraneural edema measured by dye spread in cadavers. METHODS: We systematically searched the MEDLINE, WOS, Scopus, and the Cochrane databases from inception to February 2020 for experimental studies addressing the efficacy of neurodynamic techniques on the dispersion of artificially induced intraneural edema. The DerSimonian and Laird method was used to compute pooled estimates of the mean differences (MDs) and its respective 95% confidence intervals (CIs). Subgroup analyses were conducted according to the type of neurodynamic technique. In addition, a 95% prediction interval was calculated to reflect the variation in true treatment effects in different settings, including the effect to be expected in future patients. RESULTS: Pooled results showed a significant increase in fluid dispersion (MD = 2.57 mm; 95%CI: 1.13 to 4.01). Subgroup analysis showed increased dye spread in the tensioning techniques group (MD = 2.22 mm; 95%CI: 0.86 to 3.57). CONCLUSION: Neurodynamic techniques improved the intraneural edema dispersion and should be considered for the management of peripheral compression neuropathies. Furthermore, tensioning techniques appear to be effective in helping to disperse intraneural edema.

BACKGROUND: No clear evidence is available for the influence of napping on cognitive function in older adults. This systematic review and meta-analysis aimed to elucidate the cross-sectional and longitudinal relationships between napping and cognitive function (global cognition and memory) and to explore whether some individual characteristics and sleep characteristics can modify this relationship. METHODS: We systematically searched Medline (via PubMed), Web of Science, and Scopus. DerSimonian and Lair and Hartung-Knapp-Sidik-Jonkman random effects methods were used to compute pooled estimates of odds ratios (ORs) and their respective 95% confidence intervals (95% CIs) for the association of global cognition and memory with napping. The mean age, the night sleep time (hours), and the percentage of women, no nappers, and people in the less night-time sleep duration category were used for meta-regressions. RESULTS: Twenty-five studies were included in this systematic review and meta-analysis, 18 cross-sectional and seven longitudinal studies, including 95,719 participants older than 60 years. The pooled ORs from the cross-sectional analyses were 1.03 (95% CI: 1.01 to 1.06) for global cognition and 1.06 (95%: 0.90 to 1.26) for memory. The pooled ORs from the longitudinal analyses were 1.00 (95% 0.85 to 1.18) for global cognition and 1.08 (95% 0.98 to 1.19) for memory. These associations were not modified by individual or sleep characteristics. CONCLUSION: Our data confirm the absence of association between napping and global cognition and memory regardless of the characteristics of the population. This information might be considered when providing lifestyle recommendations to adults with and without cognitive complaints.

OBJECTIVE: To estimate the prevalence of neuropsychiatric disorders, including autism spectrum disorders (ASDs), attention-deficit hyperactivity disorder (ADHD), depression, anxiety disorders, and obsessive-compulsive disorder (OCD), in populations with Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD). DATA SOURCES: MEDLINE (via PubMed), Scopus, Web of Science, and Cochrane Library from inception to November 2021. STUDY SELECTION: Observational studies of individuals with DMD or BMD that estimated the prevalence of ASDs, ADHD, depression, anxiety disorders, and OCD in each population. DATA EXTRACTION: A random-effects meta-analysis was performed on each outcome and each population (ie, DMD, BMD). DATA SYNTHESIS: Twenty-three studies were included in the meta-analysis. In DMD, there was a prevalence of 7.0% of ASDs, 18.0% of ADHD, 11.0% of depression, 24.0% of anxiety disorders, and 12.0% of OCD. Furthermore, in BMD, there was a prevalence of 6.0% of ASDs, 28.0% of ADHD, 7.0% of depression, 25.0% of anxiety disorders, and 7.0% of OCD. CONCLUSIONS: The prevalence of these neuropsychiatric disorders is higher among patients with DMD or BMD than among the general population, and the presence of these disorders may negatively influence optimal medical management.

OBJECTIVE: To estimate the screening performances of the most important provocation tests for diagnosing carpal tunnel syndrome (CTS). DESIGN: Diagnostic test accuracy systematic review with meta-analysis. LITERATURE SEARCH: We systematically searched the MEDLINE, Scopus, Web of Science, and Cochrane databases from inception to November 2020. STUDY SELECTION CRITERIA: Observational studies comparing the accuracies of the Durkan test (DT), the hand elevation test (HET), the Phalen test (PT), the Tinel test (TT), and the upper-limb neurodynamic test specific to the median nerve (ULNT1) with electrodiagnosis for screening for CTS. DATA SYNTHESIS: Random-effects models for the diagnostic odds ratio (dOR) values computed by Moses' constant for a linear model and 95% confidence intervals (CIs) were used to calculate the accuracy of these tests. Hierarchical summary receiver operating characteristic curve analyses were used to summarize the overall test performance. RESULTS: Thirty-seven studies were included in the meta-analysis, with a total sample of 2662 wrists for DT, 864 wrists for HET, 6361 wrists for PT, 6094 wrists for TT, and 571 wrists for ULNT1. The pooled dORs for screening for CTS were 15.84 (95% CI: 3.78, 66.38) for DT, 128.63 (95% CI: 40.64, 407.12) for HET, 7.23 (95% CI: 4.06, 12.86) for PT, 5.31 (95% CI: 3.49, 8.09) for TT, and 1.78 (95% CI: 0.61, 5.19) for ULNT1. CONCLUSION: HET has the best clinical performance for detecting CTS and should be considered the first screening test of choice during the physical examination. The most common tests (DT, PT, and TT) have good accuracies for screening for CTS. J Orthop Sports Phys Ther 2022;52(8):522-531. Epub: 19 June 2022. doi:10.2519/jospt.2022.10828.

OBJECTIVE: To determine which type of exercise is best for reducing pain and disability in adults with chronic low back pain (LBP). DESIGN: Systematic review with a network meta-analysis (NMA) of randomized controlled trials (RCTs). LITERATURE SEARCH: Six electronic databases were systematically searched from inception to July 2021. STUDY SELECTION CRITERIA: RCTs testing the effects of exercise on reducing self-perceived pain or disability in adults (aged 18-65 years) with chronic LBP. DATA SYNTHESIS: We followed the PRISMA-NMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, incorporating NMAs of health care interventions) statement when reporting our NMA. A frequentist NMA was conducted. The probability of each intervention being the most effective was conducted according to surface under the cumulative ranking curve (SUCRA) values. RESULTS: We included 118 trials (9710 participants). There were 28 head-to-head comparisons, 7 indirect comparisons for pain, and 8 indirect comparisons for disability. Compared with control, all types of physical exercises were effective for improving pain and disability, except for stretching exercises (for reducing pain) and the McKenzie method (for reducing disability). The most effective interventions for reducing pain were Pilates, mind-body, and core-based exercises. The most effective interventions for reducing disability were Pilates, strength, and core-based exercises. On SUCRA analysis, Pilates had the highest likelihood for reducing pain (93%) and disability (98%). CONCLUSION: Although most exercise interventions had benefits for managing pain and disability in chronic LBP, the most beneficial programs were those that included (1) at least 1 to 2 sessions per week of Pilates or strength exercises; (2) sessions of less than 60 minutes of core-based, strength, or mind-body exercises; and (3) training programs from 3 to 9 weeks of Pilates and core-based exercises.

BACKGROUND: There is overwhelming evidence regarding the beneficial effects of exercise on the management of symptoms, functionality and health-related quality of life (HRQoL) of people with multiple sclerosis (MS). However, few analyze have compared different types of exercise. OBJECTIVE: The aim of this network meta-analysis (NMA) was to assess which type of physical exercise has the greatest positive effect on HRQoL in people with MS. METHODS: MEDLINE, Cochrane Library, Embase, Web of Science, Physiotherapy Evidence Database and SPORTDiscus databases were searched from inception to June 2021 to identify randomized controlled trials (RCTs) examining the effect of physical exercise on HRQoL in people with MS. The NMA included pairwise and indirect comparisons. We ranked the effect of interventions calculating the surface under the cumulative ranking (SUCRA). RESULTS: We included 45 RCTs in this NMA (2428 participants; 76% women; mean age 45 years). Five types of physical exercises were ranked. Sensorimotor training had the highest effect size (0.87, 95% confidence interval [CI] 0.60; 1.15) and the highest SUCRA (87%) for total HRQoL. The highest effect size and SUCRA for physical and mental HRQoL were for aerobic exercise (0.85, 95% CI 0.28; 1.42) (89%) and mind-body exercises (0.54, 95% CI 0.03; 1.06) (89%). Sensorimotor training was the best exercise for mild disease and aerobic exercise for severe disease for total HRQoL. CONCLUSIONS: Sensorimotor training seems the most effective exercise to improve HRQoL and aerobic and mind-body exercises to improve physical and mental HRQoL, respectively.

OBJECTIVE: Patients with myofascial trigger points (MTPs) frequently manifest restricted range of motion (ROM) during physical evaluation. Multiple manual therapy interventions have been developed for the treatment of MTPs, but their effect on ROM has not been clarified through a systematic review and meta-analysis. Thus, this systematic review aimed to assess the effect of manual therapy interventions on ROM among individuals with MTPs. METHODS: A systematic search was conducted in PubMed, Web of Science, Cochrane, Scopus, and Clinical Trials.gov. Articles analyzing the effect of manual therapy interventions on ROM were included. The risk of bias was assessed with the Cochrane Risk of Bias (RoB) 2 tool. The DerSimonian-Laird method was used to compute the pooled effect size (ES) and its 95% confidence interval (95% CI) for ROM. RESULTS: A total of 13 randomized controlled trials were included in this systematic review and meta-analysis. The pooled ES for ROM was 0.52 (95% CI: 0.42-0.63). The pooled ES for ROM evaluated in centimeters was 0.36 (95% CI: 0.14-0.59), and the pooled ES for ROM evaluated in degrees was 0.57 (95% CI: 0.47-0.68). CONCLUSION: Manual therapy interventions may be an effective approach for improving ROM among individuals with MTPs.

OBJECTIVE: A network meta-analysis (NMA) of current evidence was conducted to determine if physical exercise has a positive influence on multiple sclerosis (MS) fatigue and type of exercise with the largest effect on fatigue also according to disease severity. DATA SOURCES: MEDLINE, Embase, SPORTDiscus, Physiotherapy Evidence Database, Cochrane Library, and Web of Science. The search strategy combined relevant terms related to (1) MS; (2) clinical trials; (3) exercise; and (4) fatigue from inception to February 2021. STUDY SELECTION: Randomized controlled trials concerning the effectiveness of different types of exercise on total and physical fatigue in people with MS were included. DATA EXTRACTION: The data were extracted into predesigned data extraction tables. Risk of bias was evaluated with the Cochrane Risk of Bias tool (RoB 2.0), and the Grading of Recommendations, Assessment, Development, and Evaluation tool was used to evaluate the quality of the evidence. DATA SYNTHESIS: A total of 58 studies were examined. Data were pooled using a random-effects model. A ranking of 7 and 8 different exercise interventions for physical and total fatigue scores, respectively, was achieved. The highest effects for pairwise comparisons were for combined exercise and resistance training vs control (ranging between -0.74 and -1.24). In the NMA, combined exercise (-1.51; 95% confidence interval [CI], -2.01 to -1.01) and resistance training (-1.15; 95% CI, -1.81 to -0.49) compared with the control group achieved the highest effects for physical and total fatigue, respectively. CONCLUSIONS: Exercise should be considered an effective fatigue management strategy. Among the different exercise modalities, combined exercise is the most effective exercise modality for improving both physical and total fatigue. Resistance training is also an effective exercise for total fatigue among people diagnosed with MS.

Obesity is declared as a chronic multifaceted health problem, and young adults may be particularly vulnerable to weight gain. This study aims to identify the role of dietary calcium intake and the muscle strength index in handling excess of fat mass in young adults and to examine if the relationship between dietary calcium intake and fat mass percentage is mediated by muscle strength. A cross-sectional study including 355 Spanish college students (aged 21.05 ± 3.11) was performed during the 2017-2018 academic year. Pearson correlation coefficients were estimated to determine the relationship between dietary calcium intake, fat mass percentage, body mass index, muscle strength components, and total energy intake. ANCOVA models were used to analyze the differences in the muscle strength index by total dietary calcium intake categories, as well as the differences in % fat mass by total dietary calcium intake and muscle strength index categories, controlling for different sets of confounders. A mediator analysis was conducted to test if the relationship between dietary calcium intake and fat mass percentage was explained by muscle strength. Data on the fat mass percentage, dietary calcium intake, and muscle strength index as the sum of the standardized z-score of the standing long jump and z-score of handgrip/weight were collected. The muscle strength index was significantly better in young adults with higher dietary calcium intake. Moreover, the fat mass percentage was significantly lower in those with a higher dietary calcium intake and a better muscle strength index. Finally, the relationship between dietary calcium intake and fat mass percentage was fully mediated by muscle strength (z = -1.90; p < 0.05), explaining 33.33% of this relationship. This study suggests that both a major dietary calcium intake and muscle strength are associated with fat mass percentage. Moreover, muscle strength mediates the link between dietary calcium intake and fat mass percentage. Therefore, both high dietary calcium intake and exercise activities aimed at improving muscle strength levels may help to prevent the cardiometabolic risk associated with an excess of fat mass in young people.

Background: Overweight/obesity is associated with the risk of delivery- and newborn-related complications in pregnancy. Interventions such as exercise or metformin could reduce the risk of these complications. Objective: To estimate and compare the effects of different types of exercise interventions (i.e., aerobic, resistance, combined exercise) and metformin on delivery- and newborn-related outcomes among pregnant women with overweight/obesity. Methods: MEDLINE, Scopus, Web of Science, Cochrane Library databases and the gray literature were searched from inception to September 2021. This systematic review was registered in PROSPERO (CDR: 42019121715). Randomized controlled trials (RCTs) of metformin or an exercise intervention aimed at preventing cesarean section, preterm birth, macrosomia, or birth weight among pregnant women with overweight/obesity were included. Random effects meta-analyses and frequentist network meta-analyses (NMA) were conducted for each outcome. Results: Fifteen RCTs were included. In the NMA, metformin reduced the risk of cesarean section (RR = 0.66, 95% CI: 0.46, 0.95), combined exercise reduced the risk of macrosomia (RR = 0.37, 95% CI: 0.14, 0.95), and aerobic exercise reduced birth weight (mean difference = -96.66 g, 95% CI: -192.45, -0.88). In the subgroup among pregnant women with obesity, metformin reduced the risk of cesarean section (RR = 0.66, 95% CI: 0.45, 0.97). Conclusions: Combined exercise could reduce the risk of macrosomia in pregnant women with overweight, whereas metformin could reduce the risk of cesarean section in pregnant women with obesity. However, previous evidence suggests a larger effect of physical exercise in other outcomes for this population group. Therefore, the medicalization of healthy pregnant women with obesity is not justified by the current evidence.

ABSTRACT
OBJECTIVES: We aimed (1) to estimate the short-term effect (postintervention period) of neurodynamic techniques on pain, symptom severity, functional status, electrophysiological status, grip strength, and pinch strength in people with carpal tunnel syndrome (CTS); and (2) to estimate the effect of neurodynamic techniques compared to other physical therapy modalities and surgical interventions. DESIGN: Intervention systematic review with meta-analysis. LITERATURE SEARCH: We searched the MEDLINE, Cochrane Database of Systematic Reviews, Web of Science, Physiotherapy Evidence Database, and Scopus databases from their inception to September 2020. STUDY SELECTION CRITERIA: We included randomized controlled trials reporting the effect of neurodynamic techniques on pain, symptom severity, function, distal motor latency, grip strength, and pinch strength in people with CTS. DATA SYNTHESIS: Using the DerSimonian-Laird method, we estimated pooled standardized mean differences (SMDs) and 95% confidence intervals (CIs). We used the Grading of Recommendations Assessment, Development and Evaluation approach to judge the certainty of the evidence of each pairwise comparison. RESULTS: There were 22 trials included (n = 1203 people with CTS; mean age, 26.0 to 57.9 years; mean symptom duration, 4.1 to 62.8 months). There was very low-certainty evidence of neurodynamic techniques improving pain (SMD, -0.54; 95% CI: -0.95, -0.13) and function (SMD, -0.35; 95% CI: -0.61, -0.09). There was no significant effect on symptom severity (very low certainty), distal motor latency (very low certainty), and grip and pinch strength (low certainty). CONCLUSION: Neurodynamic techniques were effective for improving pain and function in people with CTS, albeit with very low-certainty evidence. J Orthop Sports Phys Ther 2021;51(12):566-580.
