Latin America is characterized by ethnic, geographical, cultural, and economic diversity; therefore, training in gastroenterology in the region must be considered in this context. The continent’s medical education is characterized by a lack of standards and the volume of research continues to be relatively small. There is a multiplicity of events in general gastroenterology and in sub-disciplines, both at regional and local levels, which ensure that many colleagues have access to information. Medical education programs must be based on a clinical vision and be considered in close contact with the patients. The programs should be properly supervised, appropriately defined, and evaluated on a regular basis. The disparity between the patients’ needs, the scarce resources available, and the pressures exerted by the health systems on doctors are frequent cited by those complaining of poor professionalism. Teaching development can play a critical role in ensuring the quality of teaching and learning in universities. Continuing professional development programs activities must be planned on the basis of the doctors’ needs, with clearly defined objectives and using proper learning methodologies designed for adults. They must be evaluated and accredited by a competent body, so that they may become the basis of a professional regulatory system. The specialty has made progress in the last decades, offering doctors various possibilities for professional development. The world gastroenterology organization has contributed to the speciality through three distinctive, but closely inter-related, programs: Training Centers, Train-the-Trainers, and Global Guidelines, in which Latin America is deeply involved. 展开更多

The aim of the present study was to compare the levels of maximum strength, endurance muscular and quality of life among practitioners of group gymnastics (IG) of isolated form and practitioners of group gymnastics combinated with strength training (CG). This study is characterized as observational of comparative cross-sectional design. The sample was composted by young women, trained at least for three months, without health complications. Maximum strength (1RM) and endurance muscular (repetition at 60% 1RM) of the lower limbs were evaluated in knee extension exercise, unilaterally. Overall quality of life and in four domains was evaluated by the WHOQOL-bref. Data were described by mean and standard deviation values. Outcomes were compared by independent t-test, adopting a significance level (α) of 0.05. Thirty women were evaluated (isolated gymnastic (IG), n = 15;30.13 ± 7.24 years—combined gymnastic and strength (CG), n = 15;29.46 ± 8.18 years). Similarly values were found among groups for all outcomes (p > 0.05). The results suggest that the association of strength training with gymnastics training, possibly accumulating excessive training volume, may not increase the levels of maximum strength, endurance muscular and quality of life in young women. 展开更多

Purpose: This study was to investigate the association between ulnar variance(UV) and biological and training characteristics, handgrip, and wrist pain in a group of 23 Portuguese skeletally immature male gymnasts(aged 11.2 2.5 years).Methods: Left and right UV was obtained using Hafner's procedure and skeletal age was determined by the TannereWhitehouse 3-method. A negative mean value for UV measures was observed( 2.4 to 3.6 mm) without significant differences with increasing age-category( p=0.09 to p=0.48). Significant low correlations were observed between some UV parameters and stature, fat percentage, years of training, and left handgrip strength.Results: Ten gymnasts reported wrist pain with gradual onset and UV values were very similar between painless and painful wrists.Conclusion: The findings of this study do not directly support the thesis that gymnastics training and biological variables or wrist pain are associated with UV. 展开更多

Purpose:The aim of this study was to examine systemic responses of oxidant/antioxidant status following 2 training sessions of different intensity in amateur rhythmic gymnasts.Methods:Before the experimental training,10 female gymnasts performed a gradually increased exercise test to assess maximal heart rate,maximal oxygen consumption,and anaerobic threshold.They executed 2 intermittent training sessions separated by 48 h of recovery(48 h-post R):the first was performed at low-moderate intensity(LMI)and the second at high intensity(HI).Blood samples were collected immediately preand post-training and 48 h-post R.Hydroperoxide level(OxL)and total antioxidant capacity(TAC)were photometrically measured.Results:OxL was significantly higher in post-training and 48 h-post R following HI than the same conditions after an LMI session(HI vs.LMI post-training:381.10±46.17(mean±SD)vs.344.18±27.94 Units Carratelli(U.CARR);48 h-post R:412.21±26.61 vs.373.80±36.08 U.CARR).There was no change in TAC between the 2 training sessions investigated.In LMI training,OxL significantly decreased in post-training and increased to reach the baseline at 48 h-post R,whereas TAC increased only at 48 h-post R.In HI training,OxL significantly increased to reach a high oxidative stress 48 h-post R,whereas TAC was lower in post-training than pre-training.Conclusion:The pattern of OxL and TAC levels implies different regulation mechanisms by HI and LMI training sessions.High oxidative stress induced by an HI protocol might be associated with both insufficient TAC and recovery time at 48 h necessary to restore redox balance. 展开更多

BACKGROUND: We compare educational environments(i.e. physical, emotional and intellectual experiences) of emergency medicine(EM) residents training in the United States of America(USA) and Saudi Arabia(SA).METHODS: A cross-sectional survey study was conducted using an adapted version of the validated Postgraduate Hospital Educational Environment Measure(PHEEM) survey instrument from April 2015 through June 2016 to compare educational environments in all emergency medicine residency programs in SA and three selected programs in the USA with a history of training Saudi physicians. Overall scores were compared across programs, and for subscales(autonomy, teaching, and social Support), using chi-squared, t-tests, and analysis of variance.RESULTS: A total of 219 surveys were returned for 260 residents across six programs(3 SA, 3 USA), with a response rate of 84%. Program-specific response rates varied from 79%–100%. All six residencies were qualitatively rated as "more positive than negative but room for improvement". Quantitative PHEEM scores for the USA programs were significantly higher: 118.7 compared to 109.9 for SA, P=0.001. In subscales, perceptions of social support were not different between the two countries(P=0.243); however, role autonomy(P<0.001) and teaching(P=0.005) were better in USA programs. There were no significant differences by post-graduate training year.CONCLUSION: EM residents in all three emergency medicine residency programs in SA and the three USA programs studied perceive their training as high quality in general, but with room for improvements. USA residency programs scored higher in overall quality. This was driven by more favorable perceptions of role autonomy and teaching. Understanding how residents perceive their programs may help drive targeted quality improvement efforts. 展开更多

Although American libraries had begun collecting Chinese language materials in the 19th century, notably the United States Library of Congress in 1869, Yale in 1878, Harvard in 1879, and Berkeley in 1896, East Asian studies librarianship in North America, including China studies librarianship, was not fully developed until the 1960s. There was no formal organization that represented the interest of Chinese studies librarians because there were few of them and most of them were China scholars rather than trained librarians. More than 100 years later, the number of Chinese studies librarians in North America has increased considerably, primarily in response to the demand in the field of China studies and more recently to the needs of immigrant population and the general public who has an interest in China. This paper traces the history and growth of Chinese studies librarianship in North America, documents the development of the professional organization that represents Chinese studies librarians, and examines the training programs that prepare them for their jobs. It also attempts to propose an international exchange forum aiming to bring together Chinese studies librarians in North America and librarians in China in sharing their experience and expertise to achieve the ultimate goal of serving the users. 展开更多
