Injuries prevalence in elite male artistic gymnasts

A proposta deste estudo foi investigar a prevalência de lesões na ginástica artística masculina de alto rendimento. Vinte ginastas brasileiros da categoria adulta, com 23,1 ± 6,5 anos, 13,9 ± 5,0 anos de prá- tica no esporte e 36,5 ± 4,7 horas de treino semanais, participaram do estudo. Os atletas responderam o questionário de lesões referidas, formulado a partir de estudos da literatura, para obter informações sobre as características e circunstâncias das lesões. Foram considerados dados sobre o aparelho ou evento do treinamento em que ocorreu a lesão, o local anatômico lesionado, o tecido biológico afetado e o retorno às atividades após a lesão. Os dados foram avaliados por meio de estatística descritiva, a partir das frequências absolutas e relativas. A sobrecarga de treinamento e os aparelhos solo, cavalo com alças e salto sobre a mesa foram os eventos com maior frequência de lesões. Em relação ao local anatômico, tornozelo, mãos/dedos e ombro foram as regiões mais citadas. Os tecidos ligamentares e ósseo, bem como a cápsula articular foram os tecidos biológicos mais afetados. Em relação ao retorno às atividades, 56% relataram melhora, 33% reportaram retorno ao mesmo nível prévio à lesão e 10% relataram piora do desempenho após retorno às atividades. As lesões na ginástica artística masculina estão associadas às demandas mecânicas do esporte. A análise dos fatores de risco contribui no entendimento dos mecanismos das lesões na ginástica, bem como pode auxiliar em estratégias efetivas de prevenção.The purpose of this study was to investigate the injuries prevalence in men elite artistic gymnasts. Twenty Brazilian senior gymnasts, aged 23.1 ± 6.5 years, 13.9 ± 5.0 years of practice and 36.5 ± 4.7 hours per week training, participated in this study. The athletes answered a morbidity questionnaire, formulated according to studies from the literature, for information on the injuries’ characteristics and circumstances. Information about the injury circumstances (gymnastic apparatus, overload training and physical exercises), the anatomic site injured, the affect biological tissue and the return to training after injury treatment were evaluated. Data were analyzed by descriptive statistics, absolute and relative frequencies. The training overload, and floor, pommel horse and vault were the events that presented higher injuries frequency. In relation to anatomic site, ankle, hands/fingers and shoulder were the most cited regions. The ligament, bone and articular capsule were the most affected biological tissues. In relation to gymnasts’ return to their sports activities, 56% of them reported a better condition at return, 33% reported to have returned at the same fitness level and 10% indicated that they were in a worse condition when they returned to the sports activities. The men’s artistic gymnastics injuries are related to the mechanical demands of this sport. The analysis of risk factors helps in understanding the injuries mechanisms in gymnastics, and provides relevant information that can assist in effective prevention strategies

A diterpene synthase from the sandfly Lutzomyia longipalpis produces the pheromone sobralene

Terpenes are widely used in nature for chemical communication, but our understanding of how these structurally diverse natural products are produced by insects is only now beginning to emerge. Males of the sandfly, Lutzomyia longipalpis, use terpene pheromones to lure females and other males to mating sites. This insect attracts considerable attention due to its role as a vector for the Leishmania parasite, which causes the neglected tropical disease leishmaniasis. In this study, a diterpene synthase that produces the pheromone component sobralene is identified, heterologously expressed and functionally characterized. This represents identification of a terpene synthase (TPS) from Lutzomyia and shows that insects are capable of biosynthesizing diterpenes. It offers the potential for sustainable production of this compound through biocatalysis

Exercise recommendations for people with bone metastases: Expert consensus for healthcare providers and clinical exercise professionals

Purpose: Exercise has been underutilized in people with advanced or incurable cancer despite the potential to improve physical function and reduce psychosocial morbidity, especially for people with bone metastases because of concerns over skeletal complications. The International Bone Metastases Exercise Working Group (IBMEWG) was formed to develop best practice recommendations for exercise programming for people with bone metastases on the basis of published research, clinical experience, and expert opinion. Methods: The IBMEWG undertook sequential steps to inform the recommendations: (1) modified Delphi survey, (2) systematic review, (3) cross-sectional survey to physicians and nurse practitioners, (4) in-person meeting of IBMEWG to review evidence from steps 1-3 to develop draft recommendations, and (5) stakeholder engagement. Results: Recommendations emerged from the contributing evidence and IBMEWG discussion for pre-exercise screening, exercise testing, exercise prescription, and monitoring of exercise response. Identification of individuals who are potentially at higher risk of exercise-related skeletal complication is a complex interplay of these factors: (1) lesion-related, (2) cancer and cancer treatment–related, and (3) the person-related. Exercise assessment and prescription requires consideration of the location and presentation of bone lesion(s) and should be delivered by qualified exercise professionals with oncology education and exercise prescription experience. Emphasis on postural alignment, controlled movement, and proper technique is essential. Conclusion: Ultimately, the perceived risk of skeletal complications should be weighed against potential health benefits on the basis of consultation between the person, health care team, and exercise professionals. These recommendations provide an initial framework to improve the integration of exercise programming into clinical care for people with bone metastases

Exercise for individuals with bone metastases: A systematic review

Background Exercise has the potential to improve physical function and quality of life in individuals with bone metastases but is often avoided due to safety concerns. This systematic review summarizes the safety, feasibility and efficacy of exercise in controlled trials that include individuals with bone metastases. Methods MEDLINE, Embase, Pubmed, CINAHL, PEDro and CENTRAL databases were searched up to July 16, 2020. Results A total of 17 trials were included incorporating aerobic exercise, resistance exercise or soccer interventions. Few (n=4, 0.5%) serious adverse events were attributed to exercise participation, with none related to bone metastases. Mixed efficacy results were found, with exercise eliciting positive changes or no change. The majority of trials included an element of supervised exercise instruction (n=16, 94%) and were delivered by qualified exercise professionals (n=13, 76%). Conclusions Exercise appears safe and feasible for individuals with bone metastases when it includes an element of supervised exercise instruction

Mapping development and health effects of cooking with solid fuels in low-income and middle-income countries, 2000-18 : a geospatial modelling study

Background More than 3 billion people do not have access to clean energy and primarily use solid fuels to cook. Use of solid fuels generates household air pollution, which was associated with more than 2 million deaths in 2019. Although local patterns in cooking vary systematically, subnational trends in use of solid fuels have yet to be comprehensively analysed. We estimated the prevalence of solid-fuel use with high spatial resolution to explore subnational inequalities, assess local progress, and assess the effects on health in low-income and middle-income countries (LMICs) without universal access to clean fuels.Methods We did a geospatial modelling study to map the prevalence of solid-fuel use for cooking at a 5 km x 5 km resolution in 98 LMICs based on 2.1 million household observations of the primary cooking fuel used from 663 population-based household surveys over the years 2000 to 2018. We use observed temporal patterns to forecast household air pollution in 2030 and to assess the probability of attaining the Sustainable Development Goal (SDG) target indicator for clean cooking. We aligned our estimates of household air pollution to geospatial estimates of ambient air pollution to establish the risk transition occurring in LMICs. Finally, we quantified the effect of residual primary solid-fuel use for cooking on child health by doing a counterfactual risk assessment to estimate the proportion of deaths from lower respiratory tract infections in children younger than 5 years that could be associated with household air pollution.Findings Although primary reliance on solid-fuel use for cooking has declined globally, it remains widespread. 593 million people live in districts where the prevalence of solid-fuel use for cooking exceeds 95%. 66% of people in LMICs live in districts that are not on track to meet the SDG target for universal access to clean energy by 2030. Household air pollution continues to be a major contributor to particulate exposure in LMICs, and rising ambient air pollution is undermining potential gains from reductions in the prevalence of solid-fuel use for cooking in many countries. We estimated that, in 2018, 205000 (95% uncertainty interval 147000-257000) children younger than 5 years died from lower respiratory tract infections that could be attributed to household air pollution.Interpretation Efforts to accelerate the adoption of clean cooking fuels need to be substantially increased and recalibrated to account for subnational inequalities, because there are substantial opportunities to improve air quality and avert child mortality associated with household air pollution.

Spatial, temporal, and demographic patterns in prevalence of smoking tobacco use and attributable disease burden in 204 countries and territories, 1990-2019 : a systematic analysis from the Global Burden of Disease Study 2019

Background Ending the global tobacco epidemic is a defining challenge in global health. Timely and comprehensive estimates of the prevalence of smoking tobacco use and attributable disease burden are needed to guide tobacco control efforts nationally and globally. Methods We estimated the prevalence of smoking tobacco use and attributable disease burden for 204 countries and territories, by age and sex, from 1990 to 2019 as part of the Global Burden of Diseases, Injuries, and Risk Factors Study. We modelled multiple smoking-related indicators from 3625 nationally representative surveys. We completed systematic reviews and did Bayesian meta-regressions for 36 causally linked health outcomes to estimate non-linear dose-response risk curves for current and former smokers. We used a direct estimation approach to estimate attributable burden, providing more comprehensive estimates of the health effects of smoking than previously available. Findings Globally in 2019, 1.14 billion (95% uncertainty interval 1.13-1.16) individuals were current smokers, who consumed 7.41 trillion (7.11-7.74) cigarette-equivalents of tobacco in 2019. Although prevalence of smoking had decreased significantly since 1990 among both males (27.5% [26. 5-28.5] reduction) and females (37.7% [35.4-39.9] reduction) aged 15 years and older, population growth has led to a significant increase in the total number of smokers from 0.99 billion (0.98-1.00) in 1990. Globally in 2019, smoking tobacco use accounted for 7.69 million (7.16-8.20) deaths and 200 million (185-214) disability-adjusted life-years, and was the leading risk factor for death among males (20.2% [19.3-21.1] of male deaths). 6.68 million [86.9%] of 7.69 million deaths attributable to smoking tobacco use were among current smokers. Interpretation In the absence of intervention, the annual toll of 7.69 million deaths and 200 million disability-adjusted life-years attributable to smoking will increase over the coming decades. Substantial progress in reducing the prevalence of smoking tobacco use has been observed in countries from all regions and at all stages of development, but a large implementation gap remains for tobacco control. Countries have a dear and urgent opportunity to pass strong, evidence-based policies to accelerate reductions in the prevalence of smoking and reap massive health benefits for their citizens.
