Efeito de um período de polimento na potência e capacidade anaeróbia de atletas de tae-kwon-do

The aim of the study was to analyze the effect of a tapering period on anaerobic power and capacity of tae-kwon-do athletes. Thirty-one male tae-kwon-do participants of the Brazilian Championship were selected in a non-probabilistic way. Subjects were randomly divided into two groups, namely: experimental group (EG, n = 15) and control group (CG, n = 17). Both groups followed the same training protocol up to the tapering stage. CG was submitted to training loads contained in the last two weeks of the macrocycle. Only EG was submitted to tapering. Tapering had 2 weeks duration, adopting the linear tapering method. Taekwondo Anaerobic Test was performed by athletes before the start of the season, which was named as pre-intervention, and the last week of each mesocycle [Prep I, Prep II and Tapering (only EG)]. Group vs. time effect interaction (p < 0.01) was identified for alactic anaerobic power, with an increase only in EG in tapering (p = 0.01). A significant group vs. time interaction (p <0.01) was revealed to fatigue index, improved anaerobic capacity being checked in EG only after the tapering period (p = 0.01). It was concluded that two weeks of linear type tapering optimized the anaerobic power and capacity of male tae-kwon-do athletes.O objetivo do estudo foi analisar o efeito de um período de polimento sobre a potência e capacidade anaeróbia de atletas de tae-kwon-do. Trinta e um atletas de tae-kwon-do do sexo masculino participantes do campeonato brasileiro de tae-kwon-do foram selecionados de forma não probabilística. Os atletas foram separados aleatoriamente em dois grupos, a saber: experimental (GE, n = 15) e controle (GC, n = 17). Ambos os grupos seguiram o mesmo treinamento até a fase do polimento. O GC manteve as cargas de treinamento constantes nas últimas duas semanas do macrociclo. Somente o GE realizou o polimento. O polimento teve duração de 2 semanas, adotando-se o método de polimento linear. O Taekwondo Anaerobic Test foi realizado pelos atletas antes do início da temporada, o que foi denominado como pre-intervenção, e na última semana de cada mesociclo [Preparatório I, Preparatório II e Polimento (somente para o GE)]. Foi identificado efeito de interação grupo vs. tempo (p < 0,01) para a potência anaeróbia alática, com aumento apenas no GE na fase do polimento (p = 0,01). Uma interação significante grupo vs. tempo (p < 0,01) foi revelada para o índice de fadiga, com melhoria da capacidade anaeróbia sendo verificada no GE somente após a fase de polimento (p = 0,01). Concluiu-se que duas semanas de polimento do tipo linear otimizou a potência e capacidade anaeróbia de atletas de tae-kwon-do do sexo masculino

Periodização ondulatória vs periodização linear: efeitos sobre o desempenho de jovens nadadores

O objetivo da presente investigação foi analisar o efeito de dois diferentes tipos de periodização&nbsp;(ondulatória e linear) sobre o desempenho de nadadores. Trinta e nove jovens nadadores do sexo masculino&nbsp;foram selecionados de forma não probabilística e divididos proporcionalmente e randomicamente em&nbsp;dois grupos: periodização ondulatória (PO, n=19) e periodização linear (PL, n=20). Os nadadores foram&nbsp;submetidos a 8 semanas de treinamento físico/técnico. O desempenho nas provas de 50 e 100 m livre&nbsp;foi avaliado por meio de placas eletrônicas antes e após o período de treinamento. Conduziu-se a&nbsp;análise multivariada de medidas repetidas para comparar o desempenho (50 e 100 m livre) em função&nbsp;do grupo (PO e PL) e momento (pré e pós-treinamento). Foi identificado efeito de interação grupo vs.&nbsp;tempo (p&lt;0,01) para o desempenho nos 50 m livre, com melhora no PO (∆%=-1,87; p=0,01; d=0,7) emanutenção no PL (∆%=-0,37; p=0,38; d=0,2). Achados similares foram revelados para os 100 m livre,&nbsp;com melhora no grupo PO (∆%=-1,85; p=0,01; d=0,9) e manutenção no grupo PL (∆%=-0,16; p=0,31;&nbsp;d=0,1). Concluiu-se que a periodização ondulatória foi mais eficiente para melhorar o desempenho de&nbsp;jovens nadadores quando comparada a periodização linear

A Clinical Decision Support System (KNOWBED) to Integrate Scientific Knowledge at the Bedside: Development and Evaluation Study

[Background] The evidence-based medicine (EBM) paradigm requires the development of health care professionals’ skills in the efficient search of evidence in the literature, and in the application of formal rules to evaluate this evidence. Incorporating this methodology into the decision-making routine of clinical practice will improve the patients’ health care, increase patient safety, and optimize resources use.[Objective] The aim of this study is to develop and evaluate a new tool (KNOWBED system) as a clinical decision support system to support scientific knowledge, enabling health care professionals to quickly carry out decision-making processes based on EBM during their routine clinical practice.[Methods] Two components integrate the KNOWBED system: a web-based knowledge station and a mobile app. A use case (bronchiolitis pathology) was selected to validate the KNOWBED system in the context of the Paediatrics Unit of the Virgen Macarena University Hospital (Seville, Spain). The validation was covered in a 3-month pilot using 2 indicators: usability and efficacy.[Results] The KNOWBED system has been designed, developed, and validated to support clinical decision making in mobility based on standards that have been incorporated into the routine clinical practice of health care professionals. Using this tool, health care professionals can consult existing scientific knowledge at the bedside, and access recommendations of clinical protocols established based on EBM. During the pilot project, 15 health care professionals participated and accessed the system for a total of 59 times.[Conclusions] The KNOWBED system is a useful and innovative tool for health care professionals. The usability surveys filled in by the system users highlight that it is easy to access the knowledge base. This paper also sets out some improvements to be made in the future.This project has received funding from the Andalusian Ministry of Health from Spain (reference PIN-0213-2016), and FEDER funds.Peer reviewe

Evidence of spatial clustering of childhood acute lymphoblastic leukemia cases in Greater Mexico City: report from the Mexican Inter-Institutional Group for the identification of the causes of childhood leukemia

BackgroundA heterogeneous geographic distribution of childhood acute lymphoblastic leukemia (ALL) cases has been described, possibly, related to the presence of different environmental factors. The aim of the present study was to explore the geographical distribution of childhood ALL cases in Greater Mexico City (GMC).MethodsA population-based case-control study was conducted. Children &lt;18 years old, newly diagnosed with ALL and residents of GMC were included. Controls were patients without leukemia recruited from second-level public hospitals, frequency-matched by sex, age, and health institution with the cases. The residence address where the patients lived during the last year before diagnosis (cases) or the interview (controls) was used for geolocation. Kulldorff’s spatial scan statistic was used to detect spatial clusters (SCs). Relative risks (RR), associated p-value and number of cases included for each cluster were obtained.ResultsA total of 1054 cases with ALL were analyzed. Of these, 408 (38.7%) were distributed across eight SCs detected. A relative risk of 1.61 (p&lt;0.0001) was observed for the main cluster. Similar results were noted for the remaining seven ones. Additionally, a proximity between SCs, electrical installations and petrochemical facilities was observed.ConclusionsThe identification of SCs in certain regions of GMC suggest the possible role of environmental factors in the etiology of childhood ALL

Early mobilisation in critically ill COVID-19 patients: a subanalysis of the ESICM-initiated UNITE-COVID observational study

Background Early mobilisation (EM) is an intervention that may improve the outcome of critically ill patients. There is limited data on EM in COVID-19 patients and its use during the first pandemic wave. Methods This is a pre-planned subanalysis of the ESICM UNITE-COVID, an international multicenter observational study involving critically ill COVID-19 patients in the ICU between February 15th and May 15th, 2020. We analysed variables associated with the initiation of EM (within 72 h of ICU admission) and explored the impact of EM on mortality, ICU and hospital length of stay, as well as discharge location. Statistical analyses were done using (generalised) linear mixed-effect models and ANOVAs. Results Mobilisation data from 4190 patients from 280 ICUs in 45 countries were analysed. 1114 (26.6%) of these patients received mobilisation within 72 h after ICU admission; 3076 (73.4%) did not. In our analysis of factors associated with EM, mechanical ventilation at admission (OR 0.29; 95% CI 0.25, 0.35; p = 0.001), higher age (OR 0.99; 95% CI 0.98, 1.00; p ≤ 0.001), pre-existing asthma (OR 0.84; 95% CI 0.73, 0.98; p = 0.028), and pre-existing kidney disease (OR 0.84; 95% CI 0.71, 0.99; p = 0.036) were negatively associated with the initiation of EM. EM was associated with a higher chance of being discharged home (OR 1.31; 95% CI 1.08, 1.58; p = 0.007) but was not associated with length of stay in ICU (adj. difference 0.91 days; 95% CI − 0.47, 1.37, p = 0.34) and hospital (adj. difference 1.4 days; 95% CI − 0.62, 2.35, p = 0.24) or mortality (OR 0.88; 95% CI 0.7, 1.09, p = 0.24) when adjusted for covariates. Conclusions Our findings demonstrate that a quarter of COVID-19 patients received EM. There was no association found between EM in COVID-19 patients' ICU and hospital length of stay or mortality. However, EM in COVID-19 patients was associated with increased odds of being discharged home rather than to a care facility.
