Non-invasive skin autofluorescence as a screening method for diabetic retinopathy.

Diabetic retinopathy (DR) is a public health problem and a common cause of blindness. It is diagnosed by fundus examination; however, this is a costly and time-consuming method. Non-invasive skin autofluorescence (SAF) may be an accessible, fast and simple alternative for screening and early diagnosis of DR. The aim of this study was to evaluate the accuracy of SAF as a screening method for DR. A systematic search of MEDLINE, Scopus, and Web of Science databases was performed. Random effects models for sensitivity, specificity, positive likelihood ratio (PLR) and negative likelihood ratio (NLR), diagnostic odds ratio (dOR) value and 95% CIs were used to calculate test accuracy. In addition, hierarchical summary receiver operating characteristic curves (HSROC) were used to summarise the overall test performance. Four studies were included in the meta-analysis. Pooled sensitivity and specificity were 0.79 (95% CI 0.72-0.88; I2  = 0.0%) and 0.54 (95% CI 0.32-0.92; I2  = 97.0%), respectively. The dOR value for the diagnosis of DR using SAF was 5.11 (95% CI 1.81-14.48: I2  = 85.9%). The PRL was 2.17 (95% CI 0.62-7.64) and the NRL was 0.27 (95% CI 0.07-1.03). Heterogeneity was not relevant in sensitivity and considerable in specificity. The 95% confidence region of the HSROC included all studies. SAF as a screening test for DR shows sufficient accuracy for its use in clinical settings. SAF may be an appropriate method for DR screening, and further research is needed to recommend it as a diagnostic method.

Prevalence and genotypic associations of epilepsy in Prader-Willi Syndrome: A systematic review and meta-analysis.

OBJECTIVE: To estimate the prevalence of epilepsy and febrile seizures and their association with genotype, i.e., 15q11-q13 deletions, uniparental chromosome 15 disomy (UPD) and other mutations, in the population with Prader-Willi syndrome (PWS). METHODS: A systematic search of Medline, Scopus, Web of Science and the Cochrane Library was conducted. Studies estimating the prevalence of seizures, epilepsy and febrile seizures in the PWS population were included. Meta-analyses of the prevalence of epilepsy and febrile seizures and their association with genotype using the prevalence ratio (PR) were performed. RESULTS: Fifteen studies were included. The prevalence of epilepsy was 0.11 (0.07, 0.15), similar to the prevalence of febrile seizures, with a prevalence of 0.09 (0.05, 0.13). The comparison "deletion vs. UPD" had a PR of 2.03 (0.90, 4.57) and 3.76 (1.54, 9.18) for epilepsy and febrile seizures. CONCLUSIONS: The prevalence of seizure disorders in PWS is higher than in the general population. In addition, deletions in 15q11-q13 may be associated with a higher risk of seizure disorders. Therefore, active screening for seizure disorders in PWS should improve the lives of these people. In addition, genotype could be used to stratify risk, even for epilepsy, although more studies or larger sample sizes are needed.

Steps per day and health-related quality of life in schoolchildren: the mediator role of cardiorespiratory fitness.

To analyse the relationship between steps per day and health-related quality of life (HRQoL) and cardiorespiratory fitness (CRF) and to examine whether the relationship between steps per day and HRQoL is mediated by CRF in schoolchildren. This was a cross-sectional study including 501 schoolchildren (aged 9-12 years, 47% girls), from Cuenca, Spain. Steps per day were measured using the Xiaomi Mi Band 3 Smart Bracelet, HRQoL was estimated by the KIDSCREEN-27 questionnaire, and CRF was assessed using the 20-m shuttle run test. Analysis of covariance and multivariate analysis of covariance models showed that children with a higher mean number of steps per day (> 9000 steps/day) had better HRQoL (global score, and physical and psychological well-being) and higher CRF levels than their peers with a lower number of steps per day (p < 0.05); however, these differences were no longer significant when controlling for sex, age, mother's education level, and CRF (p > 0.05). Linear regression models estimated that each 1000-step increment was associated with better CRF (ß = 0.350; 95% CI, 0.192 to 0.508). In addition, the relationship between steps per day and HRQoL was mediated by CRF (p < 0.05).    Conclusion: Steps per day are a good metric to estimate daily physical activity because of its positive relationship with CRF. Moreover, those children taking more than 9000 steps per day are associated with higher levels of physical and psychological well-being. Finally, a substantial part of the improvement in HRQoL achieved through the increase in physical activity (steps per day) is mediated by CRF. What is Known: • Physical activity is known to have a positive impact on health-related quality of life in children. Steps per day are commonly used as a measure of physical activity. • Cardiorespiratory fitness is a recognized indicator of overall health in youth. What is New: • Increments of steps per day were associated with better CRF, with a nonlinear association after approximately 9000 steps/day. • Schoolchildren with > 9000 steps/ day showed better HRQoL.

Effectiveness of eHealth Interventions Promoting Physical Activity in Children and Adolescents: Systematic Review and Meta-Analysis.

BACKGROUND: eHealth interventions have been postulated as a feasible, acceptable, and possibly effective tool to promote physical activity (PA) among children and adolescents; however, a comprehensive quantitative analysis of the effects of eHealth interventions promoting PA is lacking. OBJECTIVE: This study aims to conduct a systematic review and meta-analysis on experimental studies reporting the effects of eHealth interventions aimed at promoting PA on PA parameters and sedentary behavior parameters in children and adolescents. METHODS: The CENTRAL, MEDLINE, Embase, and Web of Science databases were searched from inception to February 2022 for randomized controlled trials that analyzed the effects of eHealth interventions aimed at promoting PA on PA and sedentary parameters in children and adolescents. The Hartung-Knapp-Sidik-Jonkman random effects method was used to determine the mean differences (MDs) with their respective 95% CIs. The risk of bias was assessed using the Risk of Bias 2 (RoB2; Cochrane) tool and its extension for cluster randomized controlled trials. The certainty of evidence was evaluated using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. RESULTS: A total of 20 trials reporting the effects of different eHealth interventions aimed at promoting PA were included. Results for each parameter were as follows: counts per minute (MD -16.11 counts, 95% CI -122.76 to 90.53; k=3; n=402; I2=69%; favoring control), steps per day (MD 593.46 steps, 95% CI -2102.27 to 3289.19; k=2; n=152; I2=0%; favoring intervention [FI]), moderate to vigorous PA (MD -1.99 min/d, 95% CI -8.95 to 4.96; k=14; n=2336; I2=86%; favoring control), light PA (MD 3.28 min/d, 95% CI -15.48 to 22.04; k=5; n=355; I2=67%; FI), screen time (MD -31.48 min/d, 95% CI -68.62 to 5.65; k=5; n=904; I2=0%; FI), and sedentary time (MD -33.12 min/d, 95% CI -57.27 to -8.97; k=8; n=819; I2=75%; FI). Our results should be interpreted cautiously because of important limitations such as the scarcity of evidence, overall risk of bias, and low to very low certainty of evidence. CONCLUSIONS: We did not find conclusive evidence regarding the impact of PA-targeted eHealth interventions on PA parameters, but the very low certainty of evidence suggests that eHealth interventions may reduce sedentary time in children and adolescents. Our results may have important scientific implications as they highlight that the rapid development of eHealth interventions to promote PA lacks robust supporting evidence.

Neonatal hyperbilirubinemia and repercussions on neurodevelopment: A systematic review.

BACKGROUND: Accumulation of bilirubin above normal levels is considered a neurological risk factor for both premature and full-term newborns. This systematic review aimed to determine the effect of neonatal hyperbilirubinemia on neurodevelopment in preterm and full-term newborns. METHODS: PubMed, EMBASE, Cochrane Library, CINAHL, PsycINFO, Scopus and Lilacs databases were searched for articles published until 1 June 2022. The quality of cohort and case-control studies was assessed with the Newcastle-Ottawa Scale, and the MINCir scale was used to evaluate the methodological quality of therapy studies or the therapeutic procedures. Premature neonates without neurological conditions and those born at term with hyperbilirubinemia as the sole risk factor were included. Studies reporting one or more neurodevelopmental outcomes were included with an inter-group comparison of a hyperbilirubinemia group versus a non-hyperbilirubinemia or non-pathological hyperbilirubinemia group. The main outcomes were auditory function, visual function, cognitive function, motor function, behavior, global development and neurological risk. RESULTS: The search identified 951 studies, 19 of which (n = 2210 newborns) were finally included. Fifteen of the cohort and case-control studies presented low risk of bias, and six studies showed high methodological quality. Within the preterm population, hyperbilirubinemia as the sole risk factor was not shown to affect neurodevelopment. Auditory, neurological and motor development alterations were found in the population of full-term newborns with hyperbilirubinemia, which were more evident during the first year of life. CONCLUSIONS: Elevated bilirubin levels may be a trigger for the onset of neurodevelopmental disorders in full-term infants during the first year of life. More studies are warranted in the preterm population with hyperbilirubinemia to draw conclusions about its impact on their neurodevelopment.

Association between severe hypoglycaemia and risk of dementia in patients with type 2 diabetes mellitus: A systematic review and meta-analysis.

The aim of this systematic review was to analyse whether there is an association between severe hypoglycaemia and the incidence of dementia in patients with type 2 diabetes mellitus. We systematically searched the MEDLINE, Scopus, and Cochrane databases from their inception until September 2022 for observational studies on the association between hypoglycaemia and the risk of dementia. The DerSimonian and Laird method was used to compute a pooled estimate of the risk for such association. Risk ratio (RR) and its respective 95% confidence interval (95% CI). Two analyses were performed to estimate the risk of dementia: (i) any hypoglycaemia versus no hypoglycaemia and (ii) a dose-response analysis for one, two, or more than three hypoglycemic events versus no hypoglycaemia. PROSPERO registration number CRD42020219200. Seven studies were included. The pooled RR for the association of severe hypoglycaemia and risk of dementia was 1.47 (95% CI: 1.24-1.74). When the dose-response trend was analysed, the pooled RR for the risk of dementia was increased according to the hypoglycaemia events as follows: 1.29 (95% CI: 1.15-1.44) for one hypoglycemic event; 1.68 (95% CI: 1.38-2.04) for two hypoglycemic events; and 1.99 (95% CI: 1.48-2.68) for three or more hypoglycemic events. Our study demonstrates a 54% higher risk of dementia among people who suffer a hypoglycaemia event compared to nonhypoglycaemia. Considering our results and the prevalence of people suffering from diabetes mellitus, health education for both newly diagnosed and already diagnosed people could be a useful tool for glycaemic control, thus avoiding hypoglycaemic events.

Exercise during pregnancy for preventing gestational diabetes mellitus and hypertensive disorders: An umbrella review of randomised controlled trials and an updated meta-analysis.

OBJECTIVE: This study aimed to provide, through an umbrella review, an overview of the effect of single exercise interventions during pregnancy on gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP). Also, to update the current evidence through an updated meta-analysis. DESIGN: Umbrella review. SETTING: PubMed, EMBASE, Web of Science, Cochrane database of systematic reviews, Epistemonikos, SPORTDiscus, Clinicaltrials.gov, and PROSPERO register were searched from the database inception until August 2021. POPULATION: Peer-reviewed systematic reviews and meta-analyses of randomised controlled trials (RCTs) and RCTs samples. METHODS: Random-effects model was used to calculate relative risk with 95% confidence interval in the updated meta-analysis. The reference category was the groups that received usual prenatal care. AMSTAR 2 and the Cochrane Collaboration tool were used to assess the quality and GRADE approach was used to assess the overall certainly of evidence. MAIN OUTCOME MEASURES: GDM and HDP relative risk. RESULTS: Twenty-three systematic reviews and meta-analyses; and 63 RCTs were included. Single exercise interventions reduced the incidence of GDM and HDP in most systematic reviews and meta-analyses. Moreover, exercise interventions during pregnancy decrease the incidence of developing GDM and GH, particularly when they are supervised, have a low to moderate intensity level, and are initiated during the first trimester of pregnancy. CONCLUSION: Based on the findings, obstetric and physical exercise professionals could recommend exercise interventions during pregnancy as an effective strategy to improve maternal outcomes.

Nut consumption and academic performance among adolescents: the EHDLA study.

PURPOSE: The aim of this study was to examine the relationship between nut consumption and academic performance in Spanish adolescents and to explore the role of sociodemographic, anthropometric, and lifestyle covariates on this association. METHODS: A cross-sectional study was carried out using a food frequency questionnaire for estimating nut consumption in the number of 20-30 g servings per week, and academic performance data were obtained from school records. Analyses of covariance were adjusted for sociodemographic, anthropometric and lifestyle covariates, including total energy intake. RESULTS: Among the 846 adolescents included in the analyses (55.3% girls, age range from 12 to 17 years), the mean ± standard deviation consumption of nuts was 2.7 ± 2.8 servings per week, while the mean of all school grades recorded was 6.5 ± 2.0. Furthermore, compared to no consumption, the consumption of ≥ 3 nut servings per week was consistently associated with higher grades in language (p for trend = 0.005), combination of language and math (p for trend = 0.026), grade point average (p for trend = 0.039), and combination of all school records (p for trend = 0.046). These associations were observed regardless of all covariates considered, although sex and socioeconomic level played a significant role in the completely adjusted models. CONCLUSION: Nut consumption is associated with higher academic performance in a representative sample of Spanish adolescents. These cross-sectional results should be confirmed in longitudinal and intervention studies.

Global prevalence of intellectual developmental disorder in dystrophinopathies: A systematic review and meta-analysis.

AIM: To estimate the global prevalence of intellectual developmental disorder (IDD) and the IDD prevalence-genotype association in Becker muscular dystrophy (BMD) or Duchenne muscular dystrophy (DMD) according to the affected isoforms of the DMD gene: Dp427, Dp140, Dp71. METHOD: Systematic searches in MEDLINE, Scopus, Web of Science, and the Cochrane Library were conducted from inception of each database to March 2022. Observational studies that determined the prevalence of IDD in the population with BMD or DMD were included. Meta-analyses of IDD prevalence and prevalence ratios of the IDD-genotype association were conducted. RESULTS: Forty-nine studies were included. The prevalence of IDD in BMD was 8.0% (95% confidence interval 5.0-11.0), and in DMD it was 22.0% (18.0-27.0). Meta-analyses of IDD-genotype association showed a deleterious association between IDD and the number of isoforms affected in DMD, with a prevalence ratio = 0.43 (0.28-0.64) and 0.17 (0.09-0.34) for Dp140+ /Dp71+ versus Dp140- /Dp71+ and Dp140+ /Dp71+ versus Dp140- /Dp71- comparisons respectively. However, in BMD, there was no association for Dp140+ /Dp71+ versus Dp140- /Dp71+ . INTERPRETATION: There is a high prevalence of IDD in BMD and DMD. Moreover, the number of isoforms affected is strongly and negatively associated with the prevalence of IDD in DMD. WHAT THIS PAPER ADDS: The global prevalence of intellectual developmental disorder (IDD) was 8% in Becker muscular dystrophy and 22% in Duchenne muscular dystrophy (DMD). The global prevalence of IDD in DMD was 12%, 29%, and 84% in participants with Dp427- /Dp140+ /Dp71+ , Dp427- /Dp140- /Dp71+ , and Dp427- /Dp140- /Dp71- genotypes respectively. In DMD, 12% and 22% of participants had abnormal performance IQ and verbal IQ values respectively.

Physical Exercise Interventions on Quality of Life in Parkinson Disease: A Network Meta-analysis.

BACKGROUND AND PURPOSE: Physical exercise is considered an effective intervention for maintaining or improving quality of life (QoL) in patients with Parkinson disease (PD), but there is no evidence showing which type of physical exercise intervention has more positive effects. This systematic review and meta-analysis aimed to synthesize the evidence regarding the effectiveness of exercise interventions on improving QoL in patients with PD, comparing different types of exercise interventions. METHODS: A literature search was conducted through January 2022. The methodological quality of the trials was assessed using the Cochrane risk of bias tool RoB2. For the meta-analysis, physical exercise interventions were classified into 5 training categories: resistance, endurance, alternative exercises, dance, and sensorimotor interventions. A standard meta-analysis and network meta-analysis were carried out to evaluate the efficacy of the different types of physical exercise interventions. RESULTS: The search retrieved 2451 studies, 48 of which were included in this network meta-analysis with a total of 2977 patients with PD. The indirect effects of the network meta-analysis showed positive results for alternative exercises (-0.46; 95% confidence interval [CI]: -0.76, -0.16), dance (-0.63; 95% CI: -1.08, -0.17), and sensorimotor interventions (-0.23; 95% CI: -0.40, -0.07) versus control comparisons. DISCUSSION AND CONCLUSIONS: More research is needed to determine the types of physical exercise interventions that are most beneficial and for which conditions of the disease they have the most positive effects.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A398 ).

Effect of different types of exercise on fitness in people with multiple sclerosis: A network meta-analysis.

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.

Apical Periodontitis and Cardiovascular Disease in Adults: A Systematic Review with Meta-Analysis.

BACKGROUND: A potential relationship between oral health and cardiovascular diseases has been proposed. However, uncertainty remains as to whether there is sufficient data to support this association. This review aims to appraise the relationship between apical periodontitis and cardiovascular disease based on data from observational studies. METHODS: The databases Medline (via PubMed) and EMBASE (via Scopus) were searched up to August 2020 for observational studies (case-control, cross-sectional, and cohort) assessing the association of apical periodontitis with cardiovascular disease among adults. Pooled relative risk/odds ratio and 95% confidence interval (CI) were estimated using a random-effects model. Sensitivity analyses and random-effects meta-regressions were performed. RESULTS: The initial search yielded 2537 documents, of which 15 were eligible for inclusion, including 8 cross-sectional studies, 5 case-control studies, and 2 cohort studies. The majority of studies enrolled both men and women, with mean age ranging from 41 to 66 years. In cross-sectional studies, the presence of apical periodontitis was significantly associated with cardiovascular disease with a combined odds ratio of 1.53 (95% CI: 1.02-2.29, p = 0.039; I2 = 75.0%; p < 0.001). In the case-control studies, the combined odds ratio did not show a significant association of apical periodontitis with cardiovascular disease (OR = 1.24; 95% CI: 0.67-2.29, p = 0.494; I2 = 82.1%; p < 0.001). The pooled risk ratio from the 2 cohort studies showed (RR = 1.27; 95% CI: 0.71-2.27, p = 0.413; I2 = 69.1%; p = 0.072) also showed no significant association between apical periodontitis and cardiovascular disease. These results should be interpreted with caution due to the high heterogeneity. CONCLUSIONS: Data derived from cross-sectional studies suggest a weak association between apical periodontitis and cardiovascular disease. As the results were not consistent across study designs, further research is recommended, namely longitudinal studies with long-term follow-up. REGISTRATION: PROSPERO database (CRD42020204379).

Effect of Manual Therapy Interventions on Range of Motion Among Individuals with Myofascial Trigger Points: A Systematic Review and Meta-Analysis.

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.

Effect of Exercise on Fatigue in Multiple Sclerosis: A Network Meta-analysis Comparing Different Types of Exercise.

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.

Effectiveness of kinesiotaping in patients with subacromial impingement syndrome: A systematic review with meta-analysis.

OBJECTIVE: To determine the effectiveness of kinesiotaping (KT) with or without co-interventions for clinical outcomes in patients with subacromial impingement syndrome (SIS). DESIGN: Systematic review with meta-analysis of randomized clinical trials. DATA SOURCES: Eight databases (MEDLINE, CENTRAL, EMBASE, PEDro, LILACS, CINAHL, SPORTDiscus, and Web of Science) were searched from inception until March 2021. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Clinical trials that determine the effectiveness of KT with or without co-interventions for clinical outcomes in patients with SIS who are older than 18 years of age. RESULTS: Ten trials for the quantitative analysis were included. For pain intensity at 1-3 weeks, the overall pooled MD was -0.73 cm, 95% CI = -1.50 to 0.04 (p = 0.06), and at 3-6 weeks, it was -0.13 cm, 95% CI = -1.37 to 0.36 (p = 0.25). For shoulder function, the MD was -0.02, 95%CI = -0.30 to 0.26 (p = 0.89). For shoulder Range of Motion (ROM) flexion, the MD was -16.70, 95% CI = -0.52 to 33.92 (p = 0.06). Additionally, there was a low to moderate quality of evidence according to the GRADE rating. CONCLUSION: Kinesiotaping with or without co-interventions was not superior to other interventions for improving shoulder pain intensity, function and ROM flexion in patients with SIS.

Mediators between physical activity and academic achievement: A systematic review.

BACKGROUND: Research has suggested the beneficial effects of physical activity (PA) on academic achievement (AA). However, the mechanisms underlying this influence remain unclear. Some proposed mechanisms include physiological, cognitive, psychological, and behavioral paths. This study aimed to analyze mediators between PA and AA in children and adolescents. METHODS: Systematic search in Medline, SPORTDiscuss, PsycInfo, Scopus, and Web of Science for observational and experimental studies, published up to March 2021. RESULTS: Twenty-eight studies (75237 participants, aged 4-16) were included. The designs of these studies were: 21 studies cross-sectional, 5 longitudinal, and 2 experimental. Eight out of nine studies analyzing fitness as a mediator reported positive results, and one reported null finding. Adiposity was a significant mediator in one study, in two only in girls, and two reported null results. Cognition as a mediator was supported by four studies, whereas two reported null results. Regarding mental well-being, 10 out of 14 studies reported positive effects, and one out of five behavioral studies found positive results. Although studies were too sparse to draw conclusions, overall, the results indicated that self-esteem, self-image, self-efficacy, stress, and health behaviors might be potential mediators in the relationship between PA and AA. All studies were rated as medium-high quality. CONCLUSION: Overall, the available evidence seems to suggest that cardiorespiratory fitness, cognition, mental well-being, and exercise-related behaviors play some role as mediators of the relationship between PA and AA. However, the cross-sectional nature of most of the reviewed studies prevents us from making any statement in terms of causal paths. Thus, well-designed follow-up and randomized controlled studies aimed not only to tests the effect of PA in AA, but also to examine the influence of mediators are required.

Effect of multicomponent exercise in cognitive impairment: a systematic review and meta-analysis.

BACKGROUND: Multicomponent physical exercise is the most recommended type of physical intervention in older adults. Experimental data suggest the relevance of the muscle-brain axis and the relationship between muscle contraction and release of brain-derived neurotrophic factor, however, the impact of this relationship on cognition remains unclear, especially in people with diagnosis of cognitive impairment. This study assesses the effect of multicomponent physical exercise on global cognition in people with mild cognitive impairment or dementia. METHODS: Randomized controlled trials published until January 2021 were searched across three electronic databases (PubMed, Scopus, and Cochrane Database). Data about exercises included in the multicomponent intervention (endurance, strength, balance, or flexibility), the inclusion of aerobic exercise, and the change in global cognition were extracted. The effect size was represented as a standardized mean difference. Risk of bias was assessed by the RoB2 tool. RESULTS: A total of 8 studies were included. The overall effect size suggested an effect of multicomponent exercise on global cognition. However, the subgroup analysis showed an effect only when aerobic exercise was included in the intervention. No effect when mild cognitive impairment and dementia were assessed separately was found. CONCLUSION: This study suggests that multicomponent physical exercise could have an effect on global cognition in people with mild cognitive impairment or dementia only when aerobic exercise is included in the intervention. Our results support the inclusion of structured physical exercise programs in the management of people with cognitive impairment.

Napping and cognitive decline: a systematic review and meta-analysis of observational studies.

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.

Frailty, depression risk and 10-year hospitalization in older adults. The FRADEA study.

OBJECTIVES: To determine whether the interaction between frailty status and depression risk is associated with hospitalization density in older adults. METHODS: Ongoing cohort study in 794 subjects aged over 70 years from Albacete (Spain). Data were collected on depression risk, frailty, hospitalizations, and covariates. Participants were categorized into six groups. RESULTS: Adjusted hospitalization risk was higher for groups of prefrail/-non depression risk (HR 1.48; 95% confidence interval (CI) 1.16-1.89), prefrail/depression risk (HR 1.73; 95% CI 1.29-2.30), frail/non depression risk (HR 1.79; 95% CI 1.22-2.62), and frail/depression risk (HR 2.12; 95% CI 1.49-3.02), compared with robust/non depression risk group (p<0.01). Frail and prefrail groups presented increased hospitalization density in the first four follow-up years. CONCLUSIONS: Depression risk changes the yearly probabilities of hospitalization in prefrail and frail groups, increasing them in the first years. Depression risk should be monitored in prefrail and frail older adults as an independent risk factor for hospitalization.

Effectiveness of hallux valgus surgery on improving health-related quality of life: A follow up study.

BACKGROUND: Hallux valgus (HV) negatively impacts health-related quality of life (HRQoL). Patientreported outcome measures (PROMs) are increasingly used in clinical studies of the foot and ankle. We aimed to evaluate the effect of HV surgery on PROMs (i.e., pain scales, general HRQoL, and region-specific scales) and radiological angles. Additionally, we aimed to determine whether the effect on these outcomes depends on the type of surgery (including open and percutaneous techniques) and if it is influenced by potential confounding factors (i.e., age, HVA, 1-2 IMA, body mass index (BMI), and distal metatarsal articular angle (DMAA). METHODS: This was a longitudinal prospective study. We collected the clinical data of all patients who underwent surgery for symptomatic HV deformity in the orthopedic department of the Virgen de la Luz Hospital of Cuenca (Spain).The clinical outcomes were assessed using the American Orthopedic Foot and Ankle Society (AOFAS) Hallux metatarsophalangeal-interphalangeal (HMI) scale, visual analogue scale (VAS), Manchester Oxford foot questionnaire (MOXFQ), short form health survey (SF-12) and European Quality of Life-5 Dimensions (EQ-5D). RESULTS: A total of 72 patients (70 women, 97.2%) were included in the study 72 (72 feet).The AOFAS pre-post-surgery score changed from 42.16 (SD: 10.11) to 83.31 (SD: 6.23). Considering AOFAS domains, the pre-post change was from 14.17 (SD: 9.15) to 33.19 (SD: 4.69) for pain, from 27.22 (SD: 3.90) to 37.94 (SD: 2.78) for function, and from 0.78 (SD: 2.38) to 12.18 (SD: 3.45) for alignment. For other clinical outcomes was VAS score from 5.01(SD: 1.26) to 1.26 (SD: 0.96) and MOXFQ score from 61.44 (SD: 7.09) to 12.35 (SD: 4.85). SF-12 (physical) changed from 36.26 (SD: 5.32) to 47.06 (SD: 4.82), SF-12 (mental) from 38.23 (SD: 8.04) to 46.49 (SD: 4.16), and EQ5-D from 0.64 (SD: 0.008) to 0.90 (SD: 0.10). CONCLUSIONS: Our data confirmed the improvements in the clinical and radiological outcomes after HV surgery, and provided some evidence of these improvements not depending on the type of surgery or on some potential confounding factors such as BMI, HVA, 1-2 IMA, and DMAA.
