Objective
To present athletic trainers with recommendations for the content and administration of the preparticipation physical examination (PPE) as well as considerations for determining safe participation in sports and identifying disqualifying conditions.Background
Preparticipation physical examinations have been used routinely for nearly 40 years. However, considerable debate exists as to their efficacy due to the lack of standardization in the process and the lack of conformity in the information that is gathered. With the continuing rise in sports participation at all levels and the growing number of reported cases of sudden death in organized athletics, the sports medicine community should consider adopting a standardized process for conducting the PPE to protect all parties.Recommendations
Recommendations are provided to equip the sports medicine community with the tools necessary to conduct the PPE as effectively and efficiently as possible using available scientific evidence and best practices. In addition, the recommendations will help clinicians identify those conditions that may threaten the health and safety of participants in organized sports, may require further evaluation and intervention, or may result in potential disqualification.Key Words: medical history, family history, sudden cardiac death, concussion, sickle cell trait, diabetes, heat illness, hydrationParticipation in organized US athletics continues to rise. During the 2010–2011 academic year, more than 7.6 million high school students took part in organized interscholastic sports, compared with 7.1 million in 2005–2006.1 Similarly, an additional 444 077 National Collegiate Athletic Association student–athletes participated in intercollegiate athletics in 2010–2011, compared with 393 509 in 2005–2006.2 This growth in participation has led to a concomitant rise in sudden death. Most sudden deaths have been attributed to congenital or acquired cardiovascular malformations involving male football and basketball players.3–5 Other causes of sudden death include heat stroke, cerebral aneurysm, asthma, commotio cordis, and sickle cell trait.4,5 As sports participation continues to increase and catastrophic death in athletes receives more attention, the medical community should consider adopting a standardized preparticipation examination (PPE) instrument that, at a minimum and to the extent possible, sets out to ensure a safe playing environment for all and to identify those conditions that might predispose an athlete to injury or sudden death.For nearly 4 decades, PPE screening has been used routinely in an attempt to identify those conditions that may place an athlete at increased risk and affect safe participation in organized sports. Few would empirically argue the potential benefits of this practice, yet considerable debate exists as to the current efficacy of the PPE, given the significant disparities that presently characterize the examination and the information gathered. Over time, the PPE has become an integral component of athletics and sports medicine programs; however, the lack of standardization in the process has created confusion. In addition, the failure to adequately define the primary objectives of the PPE has led to the consensus that, in its current form, the PPE does not address the ultimate goal of protecting the health and safety of the player.The American Medical Association Group on Science and Technology6 has asserted that every physician has 2 responsibilities to an athlete during the PPE: “(1) to identify those athletes who have medical conditions that place them at substantial risk for injury or sudden death and to disqualify them from participation or ensure they receive adequate medical treatment before participation and (2) to not disqualify athletes unless there is a compelling medical reason.” As the PPE has evolved over the years, it has become increasingly difficult to meet these standards given the many objectives that have been proposed for the screening instrument. Originally, the primary objectives of the PPE were to (1) detect life-threatening or disabling conditions, (2) identify those conditions that predispose the athlete to injury or disability, and (3) address legal and insurance requirements.7,8 Today, however, those entities charged with developing and revising the PPE (eg, state high school athletic associations, medical associations, state education departments, state health departments, legislators)9 often have different missions, and as a result, they have sought to influence the makeup of the PPE to address their specific interests. This has led to the identification of a number of secondary objectives, including but not limited to documenting athletic eligibility, obtaining parental consent for participation and emergency treatment, and improving athlete performance.9 Most notably, the PPE represents the sole source of medical evaluation for 30% to 88% of children and adolescents annually10,11 and an opportunity to identify conditions that, although not necessarily related to or requiring restriction from athletic participation, nonetheless call for additional follow-up.9 Some authors12 have advocated this practice to evaluate the general health of the athlete and to provide an opening to discuss high-risk behaviors, preventive care measures, and nonathletic concerns. Others oppose this view, stating that the PPE “should not be the sole component of health care for athletes”6 and that the PPE can only be effective if the goals remain specific and properly directed toward the demands of sport participation.6,13 相似文献182.

Background
The Duke Activity Status Index (DASI) assesses the functional capacity of patients with cardiovascular disease (CVD), but there is no Portuguese version validated for CVD.Objectives
To translate and adapt cross-culturally the DASI for the Portuguese-Brazil language, and to verify its psychometric properties in the assessment of functional capacity of patients with CVD.Methods
The DASI was translated into Portuguese, then checked by back-translation into English and evaluated by an expert committee. The pre-test version was first evaluated in 30 subjects. The psychometric properties and correlation with exercise testing was performed in a second group of 67 subjects. An exploratory factor analyses was performed in all 97 subjects to verify the construct validity of the DASI.Results
The intraclass correlation coefficient for test-retest reliability was 0.87 and for the inter-rater reliability was 0.84. Cronbach''s α for internal consistency was 0.93. The concurrent validity was verified by significant positive correlations of DASI scores with the VO2max (r = 0.51, p < 0.001). The factor analysis yielded two factors, which explained 54% of the total variance, with factor 1 accounting for 40% of the variance. Application of the DASI required between one and three and a half minutes per patient.Conclusions
The Brazilian version of the DASI appears to be a valid, reliable, fast and easy to administer tool to assess functional capacity among patients with CVD. 相似文献188.

Background and objectives
Some cognitive models propose that information processing biases and fear are reciprocally related. This idea has never been formally tested. Therefore, this study investigated the existence of a vicious circle by which confirmation bias and fear exacerbate each other.Methods
One-hundred-and-seventy-one school children (8–13 years) were first provided with threatening, ambiguous, or positive information about an unknown animal. Then they completed a computerized information search task during which they could collect additional (negative, positive, or neutral) information about the novel animal. Because fear levels were repeatedly assessed during the task, it was possible to examine the reciprocal relationship between confirmation bias and fear.Results
A reciprocal relation of mutual reinforcement was found between confirmation bias and fear over the course of the experiment: increases in fear predicted subsequent increases in the search for negative information, and increases in the search for negative information further enhanced fear on a later point-in-time. In addition, the initial information given about the animals successfully induced diverging fear levels in the children, and determined their first inclination to search for additional information.Limitations
As this study employed a community sample of primary school children, future research should test whether these results can be generalized to clinically anxious youth.Conclusions
These findings provide first support for the notion that fearful individuals may become trapped in a vicious circle in which fear and a fear-related confirmation bias mutually strengthen each other, thereby maintaining the anxiety pathology. 相似文献189.
