ItemNo Preview AvailableCircus activities as a health intervention for children, youths, and adolescents: a scoping review protocol(LIPPINCOTT WILLIAMS & WILKINS, 2022-01)OBJECTIVE: This scoping review aims to map the evidence on circus activities described and/or evaluated as a health intervention for children, youths, and adolescents. Increased understanding of how these interventions work, and gaps identified, will allow researchers and practitioners to advance the science behind these approaches. INTRODUCTION: Circus activities are proposed in the literature as a health intervention, due to their variety, non-competitive nature, and potential to develop fundamental physical and social skills. For the purposes of this review, circus activities as a health intervention are defined as aerial, acrobatic, equilibristic, and manipulation skills taught to participants to maintain, improve, or modify health, functioning, or health conditions. INCLUSION CRITERIA: English-language evidence will be considered where circus activities as a health intervention are described and/or evaluated for participants up to 24 years of age, or who are defined as children, youths, or adolescents. Literature will be excluded where the focus of the intervention is clowning, magic, or drama games, or where circus activities are not the therapeutic part of the activity. METHODS: MEDLINE (Ovid), CINAHL Complete (EBSCO), Scopus (Elsevier), PsycINFO (Ovid), ProQuest Dissertations and Theses Global, and Google Scholar will be searched for peer-reviewed and gray literature. No restriction on dates, type, methodology, or setting will be imposed, but limits will include "human" and "English language." Screening and data extraction will be performed by two independent reviewers. Reference lists of included sources will be screened. Results will be presented in diagrammatic or tabular format, alongside a narrative description, under headings aligning with the research sub-questions.

ItemIntervencoes para promover funcao fisica de criancas e jovens com paralisia cerebral: diretriz internacional de pratica clinica(WILEY, 2022-06-21)Resumo OBJETIVO Fornecer recomendações de intervenções para promoção da função física de crianças e jovens com paralisia cerebral. MÉTODO Um painel de especialistas priorizou perguntas e desfechos importantes para o paciente. Usando o Grading of Recommendations Assessment, Development and Evaluation (GRADE), o painel avaliou a certeza das evidências e fez recomendações, com consultoria de especialistas internacionais e consumidores. RESULTADOS A diretriz compreende 13 recomendações (informadas por três revisões sistemáticas, 30 estudos randomizados e cinco estudos pré‐pós). Para alcance de objetivos funcionais, recomenda‐se que a intervenção inclua objetivos escolhidos pelo cliente, prática completa da tarefa em ambientes da vida real, suporte para empoderar as famílias e uma abordagem em equipe. Idade, habilidade e preferências da criança/família precisam ser consideradas. Para melhora da habilidade da marcha, recomenda‐se marcha no solo, que pode ser complementada com treinamento em esteira. Várias abordagens podem facilitar os objetivos relacionados ao uso das mãos: terapia bimanual, terapia de contensão induzida, treino direcionado a objetivos e abordagens cognitivas. Para auto‐cuidado, prática da tarefa completa, combinada com recursos assistivos podem aumentar a independência e reduzir a sobrecarga do cuidador. A participação em objetivos de lazer pode combinar prática da tarefa completa com estratégias direcionadas para barreiras ambientais, pessoais e sociais. INTERPRETAÇÃO Intervenção para promoção da função de crianças e jovens com paralisia cerebral precisa incluir objetivos escolhidos pelo cliente e a prática da tarefa completa dos objetivos. Os clínicos devem considerar as preferências da criança/família, idade e habilidade ao selecionarem intervenções específicas.

ItemHip and groin pain prevalence and prediction in Elite Gaelic Games: 2703 male athletes across two seasons.(Wiley, 2022-05)OBJECTIVE: Hip and groin pain is highly prevalent in sub-elite Gaelic Athletic Association (GAA) athletes, but its prevalence at the elite level is unknown. The aims of this study were to report hip and groin pain prevalence in elite male athletes, to report changes in Copenhagen Hip and Groin Outcome Score (HAGOS) across two seasons and to assess if previous hip and groin pain or pre-season HAGOS could predict future hip and groin pain. METHODS: During the 2017 and 2018 pre-season male Gaelic Players Association (GPA) playing members were invited to complete two questionnaires. The first questionnaire collected demographic information including age, GAA code played (Gaelic football or Hurling) and prevalence of hip and groin pain in the previous season. The second questionnaire was the HAGOS. Step-wise logistic regression models were fitted to HAGOS subscales, to examine if pre-season HAGOS subscale scores could predict future hip and groin pain. RESULTS: The prevalence of hip and groin pain across the elite GAA cohort was 38%. Hip and groin pain in the previous season was the strongest predictor of future hip and groin pain (r2 =0.19, AUC=0.73, 95% CI 1.76-2.27) whereas pre-season HAGOS subscale scores had limited and no additional predictive ability (AUC 0.05-0.18). CONCLUSIONS: Hip and groin pain prevalence is high in elite male GAA, with one in three athletes reporting pain. Previous season hip and groin pain is the strongest predictor of future hip and groin pain, while pre-season HAGOS scores have limited ability to predict future hip and groin pain.

ItemEffects of neuromuscular gait modification strategies on indicators of knee joint load in people with medial knee osteoarthritis: A systematic review and meta-analysis.(Public Library of Science (PLoS), 2022)OBJECTIVES: This systematic review aimed to determine the effects of neuromuscular gait modification strategies on indicators of medial knee joint load in people with medial knee osteoarthritis. METHODS: Databases (Embase, MEDLINE, Cochrane Central, CINAHL and PubMed) were searched for studies of gait interventions aimed at reducing medial knee joint load indicators for adults with medial knee osteoarthritis. Studies evaluating gait aids or orthoses were excluded. Hedges' g effect sizes (ES) before and after gait retraining were estimated for inclusion in quality-adjusted meta-analysis models. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: Seventeen studies (k = 17; n = 362) included two randomised placebo-controlled trials (RCT), four randomised cross-over trials, two case studies and nine cohort studies. The studies consisted of gait strategies of ipsilateral trunk lean (k = 4, n = 73), toe-out (k = 6, n = 104), toe-in (k = 5, n = 89), medial knee thrust (k = 3, n = 61), medial weight transfer at the foot (k = 1, n = 10), wider steps (k = 1, n = 15) and external knee adduction moment (KAM) biofeedback (k = 3, n = 84). Meta-analyses found that ipsilateral trunk lean reduced early stance peak KAM (KAM1, ES and 95%CI: -0.67, -1.01 to -0.33) with a dose-response effect and reduced KAM impulse (-0.37, -0.70 to -0.04) immediately after single-session training. Toe-out had no effect on KAM1 but reduced late stance peak KAM (KAM2; -0.42, -0.73 to -0.11) immediately post-training for single-session, 10 or 16-week interventions. Toe-in reduced KAM1 (-0.51, -0.81 to -0.20) and increased KAM2 (0.44, 0.04 to 0.85) immediately post-training for single-session to 6-week interventions. Visual, verbal and haptic feedback was used to train gait strategies. Certainty of evidence was very-low to low according to the GRADE approach. CONCLUSION: Very-low to low certainty of evidence suggests that there is a potential that ipsilateral trunk lean, toe-out, and toe-in to be clinically helpful to reduce indicators of medial knee joint load. There is yet little evidence for interventions over several weeks.

ItemOral digoxin effects on exercise performance, K+ regulation and skeletal muscle Na+,K+-ATPase in healthy humans(WILEY, 2022-08-02)We investigated whether digoxin lowered muscle Na+ ,K+ -ATPase (NKA), impaired muscle performance and exacerbated exercise K+ disturbances. Ten healthy adults ingested digoxin (0.25 mg; DIG) or placebo (CON) for 14 days and performed quadriceps strength and fatiguability, finger flexion (FF, 105%peak-workrate , 3 × 1 min, fourth bout to fatigue) and leg cycling (LC, 10 min at 33% V O 2 peak ${\rm{V}}_{{{\rm{O}}}_{\rm{2}}{\rm{peak}}}$ and 67% V O 2 peak ${\rm{V}}_{{{\rm{O}}}_{\rm{2}}{\rm{peak}}}$ , 90% V O 2 peak ${\rm{V}}_{{{\rm{O}}}_{\rm{2}}{\rm{peak}}}$ to fatigue) trials using a double-blind, crossover, randomised, counter-balanced design. Arterial (a) and antecubital venous (v) blood was sampled (FF, LC) and muscle biopsied (LC, rest, 67% V O 2 peak ${\rm{V}}_{{{\rm{O}}}_{\rm{2}}{\rm{peak}}}$ , fatigue, 3 h after exercise). In DIG, in resting muscle, [3 H]-ouabain binding site content (OB-Fab ) was unchanged; however, bound-digoxin removal with Digibind revealed total ouabain binding (OB+Fab ) increased (8.2%, P = 0.047), indicating 7.6% NKA-digoxin occupancy. Quadriceps muscle strength declined in DIG (-4.3%, P = 0.010) but fatiguability was unchanged. During LC, in DIG (main effects), time to fatigue and [K+ ]a were unchanged, whilst [K+ ]v was lower (P = 0.042) and [K+ ]a-v greater (P = 0.004) than in CON; with exercise (main effects), muscle OB-Fab was increased at 67% V O 2 peak ${\rm{V}}_{{{\rm{O}}}_{\rm{2}}{\rm{peak}}}$ (per wet-weight, P = 0.005; per protein P = 0.001) and at fatigue (per protein, P = 0.003), whilst [K+ ]a , [K+ ]v and [K+ ]a-v were each increased at fatigue (P = 0.001). During FF, in DIG (main effects), time to fatigue, [K+ ]a , [K+ ]v and [K+ ]a-v were unchanged; with exercise (main effects), plasma [K+ ]a , [K+ ]v , [K+ ]a-v and muscle K+ efflux were all increased at fatigue (P = 0.001). Thus, muscle strength declined, but functional muscle NKA content was preserved during DIG, despite elevated plasma digoxin and muscle NKA-digoxin occupancy, with K+ disturbances and fatiguability unchanged. KEY POINTS: The Na+ ,K+ -ATPase (NKA) is vital in regulating skeletal muscle extracellular potassium concentration ([K+ ]), excitability and plasma [K+ ] and thereby also in modulating fatigue during intense contractions. NKA is inhibited by digoxin, which in cardiac patients lowers muscle functional NKA content ([3 H]-ouabain binding) and exacerbates K+ disturbances during exercise. In healthy adults, we found that digoxin at clinical levels surprisingly did not reduce functional muscle NKA content, whilst digoxin removal by Digibind antibody revealed an ∼8% increased muscle total NKA content. Accordingly, digoxin did not exacerbate arterial plasma [K+ ] disturbances or worsen fatigue during intense exercise, although quadriceps muscle strength was reduced. Thus, digoxin treatment in healthy participants elevated serum digoxin, but muscle functional NKA content was preserved, whilst K+ disturbances and fatigue with intense exercise were unchanged. This resilience to digoxin NKA inhibition is consistent with the importance of NKA in preserving K+ regulation and muscle function.

ItemLinking Physical Activity to Breast Cancer: Text Mining Results and a Protocol for Systematically Reviewing Three Potential Mechanistic Pathways(AMER ASSOC CANCER RESEARCH, 2022-01)Epidemiologic research suggests that physical activity is associated with a reduced risk of breast cancer, but the causal nature of this link is not clear. Investigating mechanistic pathways can provide evidence of biological plausibility and improve causal inference. This project will examine three putative pathways (sex steroid hormones, insulin signaling, and inflammation) in a series of two-stage systematic reviews. Stage 1 used Text Mining for Mechanism Prioritisation (TeMMPo) to identify and prioritize relevant biological intermediates. Stage 2 will systematically review the findings from studies of (i) physical activity and intermediates and (ii) intermediates and breast cancer. Ovid MEDLINE, EMBASE, and SPORTDiscus will be searched using a combination of subject headings and free-text terms. Human intervention and prospective, observational studies will be eligible for inclusion. Meta-analysis will be performed where possible. Risk of bias will be assessed using the Cochrane Collaboration tool, or the ROBINS-I or ROBINS-E tool, depending on study type. Strength of evidence will be assessed using the GRADE system. In addition to synthesizing the mechanistic evidence that links physical activity with breast cancer risk, this project may also identify priority areas for future research and help inform the design and implementation of physical activity interventions.See related reviews by Swain et al., p. 16 and Drummond et al., p. 28.
