    The female athlete triad is a syndrome consisting of disordered eating, amenorrhea, and osteoporosis. The syndrome is increasing in prevalence as more women are participating in sports at a competitive level. Behaviors such as intense exercise or disordered eating patterns can lead to dysregulation of the hypothalamic-pituitarian-ovarian (HPO) axis, resulting in amenorrhea. Hypothalamic amenorrhea can lead to osteoporosis and increased fracture risk. Adolescents may particularly be at risk because it is during this crucial time that females attain their peak bone mass. Prevention of the female athlete triad through education and identification of athletes at risk may decrease the incidence of long-term deleterious consequences. Treatment of the female athlete triad is initially aimed at increasing caloric intake and decreasing physical activity until there is resumption of normal menses. Treatment of decreased bone mineral density and osteoporosis in the adolescent population, however, is controversial, with new treatment modalities currently being investigated in order to aid in the management of this disorder.

    Background The study aimed to i) assess nutritional knowledge in female athletes susceptible to the Female Athlete Triad (FAT) syndrome and to compare with controls; and ii) to compare nutritional knowledge of those who were classified as being 'at risk' for developing FAT syndrome and those who are 'not at risk'. Methods In this study, participants completed General Nutritional Knowledge Questionnaire (GNKQ), the Eating Attitude Test (EAT-26) and survey measures of training/physical activity, menstrual and skeletal injury history. The sample consisted of 48 regional endurance athletes, 11 trampoline gymnasts and 32 untrained controls. Based on proxy measures for the FAT components, participants were classified being 'at risk' or 'not at risk' and nutrition knowledge scores were compared for the two groups. Formal education related to nutrition was considered. Results A considerably higher percentage of athletes were classified 'at risk' of menstrual dysfunction than controls (28.8% and 9.4%, respectively) and a higher percentage scored at or above the cutoff value of 20 on the EAT-26 test among athletes than controls (10.2% and 3.1%, respectively). 8.5% of athletes were classified 'at risk' for bone mineral density in contrast to none from the control group. Nutrition knowledge and eating attitude appeared to be independent for both athletes and controls. GNKQ scores of athletes were higher than controls but the differences between the knowledge of 'at risk' and 'not at risk' athletes and controls were inconsequential. Formal education in nutrition or closely related subjects does not have an influence on nutrition knowledge or on being classified as 'at risk' or 'not at risk'. Conclusion The lack of difference in nutrition knowledge between 'at risk' and 'not at risk' athletes suggests that lack of information is not accountable for restricted eating associated with the Female Athlete Triad.

    2017-06-01

    The female athlete triad is a medical condition observed in physically active females involving three components: 1) low energy availability with or without disordered eating, 2) menstrual dysfunction, and 3) low bone density. An individual does not need to show clinical manifestations of all three components of the female athlete triad simultaneously to be affected by the condition. Consequences of these clinical conditions may not be completely reversible, so prevention, early diagnosis, and intervention are critical. All athletes are at risk of the female athlete triad, regardless of body build or sport. All active females should be assessed for components of the triad and further evaluation should be performed if one or more components are identified. The obstetrician-gynecologist has the opportunity to screen athletes for components of the female athlete triad at comprehensive visits for preventive care. Using the menstrual cycle as a vital sign is a useful tool for identifying athletes at risk of female athlete triad and should be an integral part of the preparticipatory sports physical. The goal of treatment for those diagnosed with female athlete triad is restoration of regular menses as a clinical marker of reestablishment of energy balance and enhancement of bone mineral density. The female athlete triad is a result of energy imbalance; thus, adjusting the energy expenditure and energy availability is the main intervention. Pharmacologic treat-ment may be considered when nonpharmacologic treatment has failed. A team approach involving the patient, obstetrician-gynecologist, sports nutritionist, coaches, parents, and mental health care provider, if indicated, is optimal.

    Low energy availability (EA) in female athletes with or without an eating disorder (ED) increases the risk of oligomenorrhoea/functional hypothalamic amenorrhoea and impaired bone health, a syndrome called the female athlete triad (Triad). There are validated psychometric instruments developed to detect disordered eating behaviour (DE), but no validated screening tool to detect persistent low EA and Triad conditions, with or without DE/ED, is available. The aim of this observational study was to develop and test a screening tool designed to identify female athletes at risk for the Triad. Female athletes (n=84) with 18-39 years of age and training ≥5 times/week filled out the Low Energy Availability in Females Questionnaire (LEAF-Q), which comprised questions regarding injuries and gastrointestinal and reproductive function. Reliability and internal consistency were evaluated in a subsample of female dancers and endurance athletes (n=37). Discriminant as well as concurrent validity was evaluated by testing self-reported data against measured current EA, menstrual function and bone health in endurance athletes from sports such as long distance running and triathlon (n=45). The 25-item LEAF-Q produced an acceptable sensitivity (78%) and specificity (90%) in order to correctly classify current EA and/or reproductive function and/or bone health. The LEAF-Q is brief and easy to administer, and relevant as a complement to existing validated DE screening instruments, when screening female athletes at risk for the Triad, in order to enable early detection and intervention.

    Protecting the health of the athlete is a goal of the International Olympic Committee (IOC). The IOC convened an expert panel to update the 2005 IOC Consensus Statement on the Female Athlete Triad. This Consensus Statement replaces the previous and provides guidelines to guide risk assessment, treatment and return-to-play decisions. The IOC expert working group introduces a broader, more comprehensive term for the condition previously known as 'Female Athlete Triad'. The term 'Relative Energy Deficiency in Sport' (RED-S), points to the complexity involved and the fact that male athletes are also affected. The syndrome of RED-S refers to impaired physiological function including, but not limited to, metabolic rate, menstrual function, bone health, immunity, protein synthesis, cardiovascular health caused by relative energy deficiency. The cause of this syndrome is energy deficiency relative to the balance between dietary energy intake and energy expenditure required for health and activities of daily living, growth and sporting activities. Psychological consequences can either precede RED-S or be the result of RED-S. The clinical phenomenon is not a 'triad' of the three entities of energy availability, menstrual function and bone health, but rather a syndrome that affects many aspects of physiological function, health and athletic performance. This Consensus Statement also recommends practical clinical models for the management of affected athletes. The 'Sport Risk Assessment and Return to Play Model' categorises the syndrome into three groups and translates these classifications into clinical recommendations.

    Since the passage of Title IX in 1972, female sports participation has dramatically increased. The benefits of physical activity, including decreased risk for heart disease and diabetes as well as improved body image and self-esteem, far outweigh the risks. However, a select population of adolescent and young adult females may experience symptoms related to the female athlete triad (Triad), which refers to the interrelatedness of energy availability, menstrual function, and bone mineral density (BMD). These conditions often manifest clinically as disordered eating behaviors, menstrual irregularity, and stress fractures; an individual may suffer from 1 or all of the Triad components simultaneously. Because of the complex nature of the Triad, treatment is challenging and requires a multidisciplinary approach. Team members often include a physician, psychologist or psychiatrist, nutritionist or dietitian, physical therapist, athletic trainer, coach, family members, and most importantly, the patient. A thorough physical examination by a primary care physician is essential to identify all organs/systems that may be impacted by Triad-related conditions. Laboratory tests, assessment of bone density, nutritional assessment, and behavior health evaluation guide the management of the female athlete with Triad-related conditions. Treatment of the Triad includes adequate caloric consumption to restore a positive energy balance; this is often the first step in successful management of the Triad. In addition, determining the cause of menstrual dysfunction (MD) and resumption of menses is very important. Nonpharmacologic interventions are the first choice; pharmacologic treatment for MD is reserved only for those patients with symptoms of estrogen deficiency or infertility. Lastly, adequate intake of calcium and vitamin D is critical for lifelong bone health. For this review, a comprehensive search of relevant databases from the earliest dates to July 2016 was performed. Keywords

  12. Current perspectives on the etiology and manifestation of the “silent” component of the Female Athlete Triad

    2014-01-01

    The Female Athlete Triad (Triad) represents a syndrome of three interrelated conditions that originate from chronically inadequate energy intake to compensate for energy expenditure; this environment results in insufficient stored energy to maintain physiological processes, a condition known as low energy availability. The physiological adaptations associated with low energy availability, in turn, contribute to menstrual cycle disturbances. The downstream effects of both low energy availability and suppressed estrogen concentrations synergistically impair bone health, leading to low bone mineral density, compromised bone structure and microarchitecture, and ultimately, a decrease in bone strength. Unlike the other components of the Triad, poor bone health often does not have overt symptoms, and therefore develops silently, unbeknownst to the athlete. Compromised bone health among female athletes increases the risk of fracture throughout the lifespan, highlighting the long-term health consequences of the Triad. The purpose of this review is to examine the current state of Triad research related to the third component of the Triad, ie, poor bone health, in an effort to summarize what we know, what we are learning, and what remains unknown.

    To evaluate the screening practices and preparticipation evaluation (PPE) forms used to identify college athletes at risk for the female athlete triad (triad). Phone and/or e-mail survey. National Collegiate Athletic Association (NCAA) Division I universities. All 347 NCAA Division I universities were invited to participate in a survey, with 257 participating in the survey (74%) and 287 forms collected (83%). Information about the nature of the PPE was requested from team physicians and certified athletic trainers during a phone or e-mail survey. In addition, a copy of their PPE form was requested to evaluate for inclusion of the 12 items recommended by the Female Athlete Triad Coalition for primary screening for the triad. All 257 universities (100%) required a PPE for incoming athletes; however, only 83 universities (32%) required an annual PPE for returning athletes. Screening was performed on campus at 218 universities (85%). Eleven universities (4%) were using the recently updated fourth edition PPE. Only 25 universities (9%) had 9 or more of the 12 recommended items included in their forms, whereas 127 universities (44%) included 4 or less items. Relevant items that were omitted from more than 40% of forms included losing weight to meet the image requirements of a sport; using vomiting, diuretics, and/or laxatives to lose weight; and the number of menses experienced in the past 12 months. The current PPE forms used by NCAA Division I universities may not effectively screen for the triad.

    The female athlete triad is an increasingly prevalent condition involving disordered eating, amenorrhea, and osteoporosis. An athlete can suffer from all 3 components of the triad, or just 1 or 2 of the individual conditions. The main element underlying all the aspects of the triad is an adaptation to a negative caloric balance. Screening for these disorders should be an important component of an athlete's care. Prevention and treatment should involve a team approach, including a physician, a nutritionist, and a mental health provider. Copyright 2010 Elsevier Inc. All rights reserved.

    The female athlete triad (Triad), links low energy availability (EA), with menstrual dysfunction (MD), and impaired bone health. The aims of this study were to examine associations between EA/MD and energy metabolism and the prevalence of Triad-associated conditions in endurance athletes. Forty women [26.2 ± 5.5 years, body mass index (BMI) 20.6 ± 2.0 kg/m(2), body fat 20.0 ± 3.0%], exercising 11.4 ± 4.5 h/week, were recruited from national teams and competitive clubs. Protocol included gynecological examination; assessment of bone health; indirect respiratory calorimetry; diet and exercise measured 7 days to assess EA; eating disorder (ED) examination; blood analysis. Subjects with low/reduced EA (< 45 kcal/kg FFM/day), had lower resting metabolic rate (RMR) compared with those with optimal EA [28.4 ± 2.0 kcal/kg fat-free mass (FFM)/day vs 30.5 ± 2.2 kcal/kg FFM/day, P < 0.01], as did subjects with MD compared with eumenorrheic subjects (28.6 ± 2.4 kcal/kg FFM/day vs 30.2 ± 1.8 kcal/kg FFM/day, P < 0.05). 63% had low/reduced EA, 25% ED, 60% MD, 45% impaired bone health, and 23% had all three Triad conditions. 53% had low RMR, 25% hypercholesterolemia, and 38% hypoglycemia. Conclusively, athletes with low/reduced EA and/or MD had lowered RMR. Triad-associated conditions were common in this group of athletes, despite a normal BMI range. The high prevalence of ED, MD, and impaired bone health emphasizes the importance of prevention, early detection, and treatment of energy deficiency. © 2014 John Wiley & Sons A/S.

    Objective To determine the prevalence of the female athlete triad (low energy availability, menstrual dysfunction and low bone mineral density) in high school varsity athletes in a variety of sports compared with sedentary students/controls. Design Prospective study. Setting Academic medical center in the Midwest. Participants Eighty varsity athletes and eighty sedentary students/controls volunteered for this study. Intervention Subjects completed questionnaires, had their blood drawn and underwent bone mineral density testing. Main Outcome Measures Each participant completed screening questionnaires assessing eating behavior, menstrual status and physical activity. Each subject completed a 3-day food diary. Serum hormonal, TSH and prolactin levels were determined. Bone mineral density (BMD) and body composition were measured by dual energy x-ray absorptiometry (DXA). Results Low energy availability was present in similar numbers of athletes (36%) and sedentary/control subjects (39%; p=0.74). Athletes suffered more menstrual abnormalities (54%) compared with sedentary students/controls (21%) (p=<0.001). DXA revealed that 16% of the athletes and 30% of the sedentary/controls had low BMD (p=0.03). Risk factors for reduced BMD include sedentary control student, low BMI and increased caffeine consumption. Conclusions A substantial number of high school athletes (78%) and a surprising number of sedentary students (65%) suffer from one or more components of the triad. Given the high prevalence of triad characteristics in both groups, education in the formative elementary school years has the potential to prevent several of the components in both groups, therefore, improving health and averting long-term complications.

    The female athlete triad (referred to as the triad) contributes to adverse health outcomes, including bone stress injuries (BSIs), in female athletes. Guidelines were published in 2014 for clinical management of athletes affected by the triad. This study aimed to (1) classify athletes from a collegiate population of 16 sports into low-, moderate-, and high-risk categories using the Female Athlete Triad Cumulative Risk Assessment score and (2) evaluate the predictive value of the risk categories for subsequent BSIs. Cohort study; Level of evidence, 3. A total of 323 athletes completed both electronic preparticipation physical examination and dual-energy x-ray absorptiometry scans. Of these, 239 athletes with known oligomenorrhea/amenorrhea status were assigned to a low-, moderate-, or high-risk category. Chart review was used to identify athletes who sustained a subsequent BSI during collegiate sports participation; the injury required a physician diagnosis and imaging confirmation. Of 239 athletes, 61 (25.5%) were classified into moderate-risk and 9 (3.8%) into high-risk categories. Sports with the highest proportion of athletes assigned to the moderate- and high-risk categories included gymnastics (56.3%), lacrosse (50%), cross-country (48.9%), swimming/diving (42.9%), sailing (33%), and volleyball (33%). Twenty-five athletes (10.5%) assigned to risk categories sustained ≥1 BSI. Cross-country runners contributed the majority of BSIs (16; 64%). After adjusting for age and participation in cross-country, we found that moderate-risk athletes were twice as likely as low-risk athletes to sustain a BSI (risk ratio [RR], 2.6; 95% confidence interval [95% CI], 1.3-5.5) and high-risk athletes were nearly 4 times as likely (RR, 3.8; 95% CI, 1.8-8.0). When examining the 6 individual components of the triad risk assessment score, both the oligomenorrhea/amenorrhea score ( P = .0069) and the prior stress fracture/reaction score ( P = .0315) were identified as independent

    Our aim was to examine inclusion of screening questions related to female athlete triad in the Canadian Interuniversity Sport (CIS) pre-participation evaluation (PPE) forms. We hypothesized that the current CIS PPE forms are not comprehensive screening tools for identifying athletes at risk for the female athlete triad. All 48 English-speaking CIS universities were invited to participate in the study. Via e-mail, a copy of the PPE form was requested from team physicians and certified athletic trainers. Two reviewers evaluated the PPE forms for inclusion of the 12 items recommended by the Female Athlete Triad Coalition for primary screening for the triad. Thirty-nine of 48 CIS universities responded (81%). The majority of the universities (97%), required a PPE for incoming athletes. Only 9 universities (24%) had 6 or more of the 12 recommended screening items included in their forms, whereas 26 universities (70%) included 4 or less items. Three universities (8%) did not address any of the recommended questions. Questions related to disordered eating were often absent in the collected PPEs. In 10 universities (27%), PPE forms were completed by the athlete alone. The remaining 27 (73%) universities required the form to be completed by the athlete in conjunction with a therapist, physician, or both. PPE forms used by CIS universities have limited ability to identify athletes at risk of the triad-based on the recommendations of the Coalition. Furthermore, there is a lack of uniformity of the PPE forms within the CIS.

    Peak bone mass (PBM) is a negative predictor of osteoporosis and life-long fracture risk. Because osteoporosis is such a prevalent disease with life-threatening consequences later in life, it is important to try to maximize PBM. Adolescence is a critical time for bone acquisition. This review discusses some of the differences in male and female skeletal development and modifiable factors that enhance bone accrual in this age group, particularly in athletes. Hormonal influences, physical activity effects, and nutritional contributions are presented, with a focus on the adolescent athlete. Emphasis is placed on the importance of appropriate energy availability in this age group. The Female Athlete Triad (the inter-relationship of decreased energy availability, menstrual irregularity, and low bone density) is an important issue for adolescent, athletic women, and is therefore reviewed, including prevention and treatment strategies. Recommendations for maximizing bone density in both male and female adolescents are discussed. PMID:21378496

    To determine the prevalence of the female athlete triad in club triathletes. Cross-sectional. Academic medical center in the midwestern United States. Fifteen women (mean age, 35+/-6 y). Not applicable. Disordered eating and menstrual status were determined by questionnaires. Energy status was determined by a 3-day food record, resting energy expenditure, and exercise energy output. Bone mineral density (BMD) was measured in the total left hip and lumbar spine (L2-4) by dual-energy x-ray absorptiometry. Sixty percent of the triathletes were found to be in calorie deficit, 53% had a carbohydrate deficit, 47% had a fat deficit, 40% had a protein deficit, and 33% had a calcium deficit. Forty percent of triathletes reported a history of amenorrhea. BMD was normal in the lumbar spine (L2-4) (1.3+/-0.1 g/cm(2)) and total left hip (1.1+/-0.1 g/cm(2)). Triathletes are at risk for components of the female athlete triad. Continued efforts need to be directed at prevention through education of athletes, coaches, parents, and health care professionals.

    Maintaining low body weight for the sake of performance and aesthetic purposes is a common feature among young girls and women who exercise on a regular basis, including elite, college and high-school athletes, members of fitness centres, and recreational exercisers. High energy expenditure without adequate compensation in energy intake leads to an energy deficiency, which may ultimately affect reproductive function and bone health. The combination of low energy availability, menstrual disturbances and low bone mineral density is referred to as the 'female athlete triad'. Not all athletes seek medical assistance in response to the absence of menstruation for 3 or more months as some believe that long-term amenorrhoea is not harmful. Indeed, many women may not seek medical attention until they sustain a stress fracture. This review investigates current issues, controversies and strategies in the clinical management of bone health concerns related to the female athlete triad. Current recommendations focus on either increasing energy intake or decreasing energy expenditure, as this approach remains the most efficient strategy to prevent further bone health complications. However, convincing the athlete to increase energy availability can be extremely challenging. Oral contraceptive therapy seems to be a common strategy chosen by many physicians to address bone health issues in young women with amenorrhoea, although there is little evidence that this strategy improves bone mineral density in this population. Assessment of bone health itself is difficult due to the limitations of dual-energy X-ray absorptiometry (DXA) to estimate bone strength. Understanding how bone strength is affected by low energy availability, weight gain and resumption of menses requires further investigations using 3-dimensional bone imaging techniques in order to improve the clinical management of the female athlete triad.

    The purpose of this study was to determine what coaches of female athletes know about the three components of the female athlete triad with regard to type of sport coached and the characteristics of the coach. The sample consisted of 309 NCAA Division I coaches of female athletes in the sports of: sports with subjective scoring of performance (gymnastics and diving), low body weight sports (cross country and rowing), revealing or fitted clothing (volleyball and swimming), and other (soccer and basketball). An original, self-report questionnaire, and a 4-point Likert scale to measure confidence in answer was used. The variables were: knowledge, confidence, and coach's characteristics (coach's gender, degree held, years of experience in coaching females, continuing education participation specific to the triad and triad components, and type of sport coached). Coaches of low body weight sports scored significantly higher than both coaches of sports requiring fitted clothing and "other" sports in the overall score. They further had significantly more confidence in their answers than coaches of "other" sports. No significant differences in the overall score in any of the types of sport or total values were found regarding gender, experience, and degree. Coaches who had received training about the triad or its components scored significantly higher than coaches who did not receive training. The results demonstrated a lack of information among coaches and that participating in formative training can help to reduce this problem. The results found can help in the design of continuing education for coaches.

    The purpose of this study was to survey universities affiliated with Canadian Interuniversity Sport on existing screening protocols for the female athlete triad, and to identify any potential areas for improvement of this system. Surveys were faxed or e-mailed to Canadian Interuniversity Sport-affiliated universities in Canada, and preparticipation physical examination (PPE)/medical history forms from each institution were analyzed. The Fowler Kennedy Sports Medicine Clinic at the University of Western Ontario. In 2000, of the 48 universities, 35 responded (73.0% response rate). In 2002, 39 of 49 universities responded (79.6%). Although the majority of institutions surveyed implement a PPE form (80.0% in 2000, 87.2% in 2002), only 70.6% to 75.0% of these institutions actually conduct a follow-up when deemed necessary. However, the number of forms including a specific female section increased from 46.4% in 2000 to 61.8% in 2002. Also encouraging is the percentage of universities attempting to increase awareness of the triad disorders (33.3% in 2002 vs. 14.3% in 2000). It is interesting to note that in over half of the institutions surveyed both years, the athletic therapist or trainer is responsible for analyzing the completed PPE forms. This study has shown substantial improvement from 2000 to 2002 in the development of the PPE across Canada, even in a relatively short period of 2 years. However, this study also demonstrates the lack of uniformity within Canada of the PPE forms. There remains a need to improve the PPE form to target a section of the form specifically to female athletes, or else cases may be missed. The triad is also not found solely in sports where leanness is associated with better performance. Better efforts need to made to increase awareness of the triad and its risks among female athletes, as well as provide educational opportunities for athletic therapists, who are the first line of intervention in many cases.

    Orbital complications are uncommon in adult sinusitis. In contrast, the sinusitis of the aspirin triad syndrome is often fulminate, expansive, and recurrent, and complications may be more frequent. Of 81 patients with aspirin triad who were treated surgically, 7 patients (8.6%) had orbital complications, including sinus mucoceles in 3 patients, lacrimal gland extension in 2 patients, inflammatory orbital mass in 1 patient, and proptosis from expansile sinonasal polyposis in 1 patient. All complications manifested within 2 years of prior surgery. Two patients suffered blindness. In a group of 120 consecutively treated sinus surgery patients without aspirin triad syndrome (51 of whom were followed for more than 2 years), no patient manifested nonoperative orbital complications. The results of this study suggest that aspirin triad patients are at significant risk for orbital complications and therefore should have long-term follow-up with aggressive treatment of persistent disease.

  10. Female Athlete Triad/Relative Energy Deficiency in Sport: A Perspective Interview With Professor Barbara Drinkwater.

    Barbara Drinkwater has been a lifelong champion of equality for women in many areas of life well before it was widely accepted. Her "walking the walk" of women breaking barriers in traditional male roles in administration and leadership is exemplified by her election as the first woman president of the American College of Sports Medicine in 1988. Some of the controversial areas in which Barbara was vocal in the arena of women in sport, besides triad/relative energy deficiency in sport, include increased opportunity and participation, total equality, acceptance of diversity, intolerance of harassment and abuse, and fairness with transgender athletes. She co-founded the evidence-based advocacy group on the international stage known as Women Sport International. As a physiologist, Barbara has had a major influence on attention to the health of the female athlete, and she produced the original pioneering work in the field. Her impactful study, "Bone mineral density after resumption of menses in amenorrheic athletes," was published in the Journal of the American Medical Association in 1986. Since that time, the female athlete triad has set the stage for research and treatment to enhance women in physical activity at all levels.

    Objective To determine the prevalence of the 3 components of the female athlete triad [disordered eating, menstrual dysfunction, low bone mineral density (BMD)] and their relationships with brachial artery flow-mediated dilation in professional dancers. Design Prospective study. Setting Academic institution in the Midwest. Participants Twenty-two professional ballet dancers volunteered for this study. Interventions The prevalence of the female athlete triad and its relationship to endothelial dysfunction. Main Outcome Measures Subjects completed questionnaires to assess disordered eating and menstrual status/history. They also completed a 3-day food record and wore an accelerometer for 3 days to determine energy availability. Serum baseline thyrotropin, prolactin, and hormonal concentrations were obtained. Bone mineral density and body composition were measured with a GE Lunar Prodigy dual-energy X-ray absorptiometry. Endothelial function was determined as flow-mediated vasodilation measured by high-frequency ultrasound in the brachial artery. An increase in brachial diameter <5% to hyperemic flow stimulus was defined a priori as endothelial dysfunction. Results Seventeen dancers (77%) had evidence of low/negative energy availability. Thirty-two percent had disordered eating (EDE-Q score). Thirty-six percent had menstrual dysfunction and 14% were currently using hormone contraception. Twenty-three percent had evidence of low bone density (Z-score < −1.0). Sixty-four percent had abnormal brachial artery flow-mediated dilation (<5%). Flow-mediated dilation values were significantly correlated with serum estrogen and whole-body and lumbar BMD. All the 3 components of the triad plus endothelial dysfunction were present in 14% of the subjects. Conclusions Endothelial dysfunction was correlated with reduced BMD, menstrual dysfunction, and low serum estrogen. These findings may have profound implications for cardiovascular and bone health in professional women dancers

    Prevention of the female athlete triad is essential to protect female athletes' health. The aim of this study was to investigate the knowledge, attitudes, and behaviors of regularly exercising adult women in Australia toward eating patterns, menstrual cycles, and bone health. A total of 191 female exercisers, age 18-40 yr, engaging in ≥2 hr/wk of strenuous activity, completed a survey. After 11 surveys were excluded (due to incomplete answers), the 180 participants were categorized into lean-build sports (n = 82; running/athletics, triathlon, swimming, cycling, dancing, rowing), non-lean-build sports (n = 94; basketball, netball, soccer, hockey, volleyball, tennis, trampoline, squash, Australian football), or gym/fitness activities (n = 4). Mean (± SD) training volume was 9.0 ± 5.5 hr/wk, with participants competing from local up to international level. Only 10% of respondents could name the 3 components of the female athlete triad. Regardless of reported history of stress fracture, 45% of the respondents did not think that amenorrhea (absence of menses for ≥3 months) could affect bone health, and 22% of those involved in lean-build sports would do nothing if experiencing amenorrhea (vs. 3.2% in non-lean-build sports, p = .005). Lean-build sports, history of amenorrhea, and history of stress fracture were all significantly associated with not taking action in the presence of amenorrhea (all p < .005). Few active Australian women are aware of the detrimental effects of menstrual dysfunction on bone health. Education programs are needed to prevent the female athlete triad and ensure that appropriate actions are taken by athletes when experiencing amenorrhea.

    The physical and mental health complex is claimed as achievement of the XXI. century, whereby also among the sportsmen and sportswomen, beside the somatic medicine, growing attention is devoted to the psyche as well. The sports psychiatry was dragged in and put into service to enhance performance after all biological weapons run out of ammunition, and the long-awaited results still failed to come about. Moreover, despite the energy increasingly invested it was going from bad to worse. Among athletes many psychiatric disorders call attention, either by the high prevalence or by the development of a specific syndrome. Symptoms of depression (depression after the competition, depression following the failure at the competition), chronic stress, anxiety, fatigue syndrome of overtraining, enervation, sleep disturbances, eating problems, burnout, eating disorders (anorexia athletics, athlete triad), personality factors and the chemical addiction are all extremely important. The present study is the first to summarize the most crucial psychiatric disorders that may have great significance in the athlete population, in varying degrees according to the individual sports.

    Inadequate dietary intake is the primary nutritional concern of today's female athlete. As these athletes fail to consume enough energy to support the physical demands of training, they become at risk for disordered eating, amenorrhea, and osteoporosis, conditions collectively identified as the female athlete triad. This review addresses nutritional concerns of the female athlete, identification of those at risk, relationship of energy intake to menstrual irregularities, and recently identified chronic diseases associated with the female athlete triad. Strategies are offered to prevent harmful behaviors leading to the comorbidities associated with inadequate dietary intakes.

    Dysfunction of the shoulder joint is based not only on anatomic conditions. The consideration of the special kinesiology of the shoulder helps to understand the shoulder pathology. This mainly applies to young "overhead athletes" like swimmers, handball-, basketball-, volleyball-, and racketplayers. These disciplines cause stress on the anterior joint structures (capsule, ligaments, labrum, subscapularis tendon) and lead to anterior instability. This includes anterior subluxation or even dislocation. Finally, an impingement syndrome with the typical symptoms can frequently result from these conditions. The impingement-syndrome of the elderly must be considered as a primary disease, whereas the young overhead athlete suffers from the impingement syndrome as a secondary disease and does not take the first place in therapy. The first step in therapy should to be treat the muscular imbalance of the shoulder. To gain a regular pattern of motion the rotator cuff must be strengthened. This regimen is likely to be successful in 80-90% of the cases. If the conservative therapy fails the surgical treatment may come into consideration. Arthroscopic surgery has the advantage not to affect the proprioceptivity. To retain the previous level of performance an adequate rehabilitation programme is essential for the athlete.

    Background In 1992, the concept of female athlete triad was introduced to describe the interrelated problems of amenorrhea, eating disorders and osteoporosis seen in female athletes. To gain a clearer picture of amenorrhea/oligomenorrhea in Iran, one of the main components of the female athlete triad, we therefore established this study on the prevalence of amenorrhea/oligomenorrhea in elite Iranian female athletes, also evaluating the risk factors of these disorders in the same population. Methods This study performed as a cross-sectional study. All elite Iranian female athletes of 34 sports federation, including female athletes in national teams and medalists of Tehran were invited to participate. A total of 788 (95% response rate) returned the questionnaires and were examined. Younger athletes under the age of menarche were excluded. Each athlete completed a self-administered questionnaire, which covered the following questions about participant's demographic information, athletic history, history of injuries and menstrual pattern. In order to diagnose the causes of amenorrhea/Oligomenorrhea including polycystic ovary syndrome(PCOS), participants with amenorrhea/Oligomenorrhea underwent further investigation. They were evaluated by following Para clinic investigation, and an ultrasonographic study of ovary. Results The age ranged from 13–37 (mean = 21.1, SD = 4.5). Seventy one (9.0%) individuals had amenorrhea/oligomenorrhea, among those, 11 (15.5%) had PCOS. There was also a positive association between amenorrhea/oligomenorrhea and the following: age under 20 OR; 2.67, 95%CI(1.47 – 4.85), weight class sports OR; 2.09, 95%CI(1.15 – 3.82), endurance sports OR; 2.89, 95%CI(1.22 – 6.84), late onset of menarche OR; 3.32 95%CI(1.04–10.51), and use of oral contraceptive pills OR; 6.17, 95%CI(3.00 – 12.69).

    Stress fractures are a common type of overuse injury in athletes. Females have unique risk factors such as the female athlete triad that contribute to stress fracture injuries. We review the current literature on risk factors for stress fractures, including the role of sports participation and nutrition factors. Discussion of the management of stress fractures is focused on radiographic criteria and anatomic location and how these contribute to return to play guidelines. We outline the current recommendations for evaluating and treatment of female athlete triad. Technologies that may aid in recovery from a stress fracture including use of anti-gravity treadmills are discussed. Prevention strategies may include early screening of female athlete triad, promoting early participation in activities that improve bone health, nutritional strategies, gait modification, and orthotics.

    Symptomatic accessory navicular syndrome (ANS) typically develops in young athletes. The symptoms are exacerbated during exercise or while walking, affecting the sports performance of athletes. The purpose of this study was to evaluate the radiologic findings and clinical course in athletes with accessory navicular syndrome (ANS) in comparison with a nonathletic population. Seventy-nine patients with ANS between August 2012 and August 2013 were included. Overall, 29 were athletes and 50 were not athletes, and 19 (2 athletes and 17 nonathletes) of them improved after at least 6 months of conservative treatment. The records of 60 patients (64 consecutive feet) of ANS treated by modified Kidner operation were evaluated retrospectively. The study population included 27 athletes (31 feet) and 33 nonathletes (33 feet). Clinical features and radiologic findings were compared between them. Overall, 34% of the nonathletes improved after conservative treatment, but only 6.9% of athletes improved (P < .001). Mean age at surgery in the athlete group was 16.1 years (range, 12-26), and 24.3 years (range, 12-52) in the nonathlete group (P < .001). There was a history of trauma in 23 feet (74%) of the athlete group and in 13 feet (39%) of the nonathlete group (P = .006). Eighteen feet (58%) in the athlete group and 11 feet (32%) in the nonathlete group showed movement between the 2 bones (P = .047). Bone marrow edema was observed in both navicular and accessory navicular in all of the athletes (27/27, 100%). But it was only present in 80% (16/20) for nonathletes (P = .012). The radiologic findings and clinical course of athletes were different from that of the general population. Their symptoms were more refractory to conservative treatment than the nonathletes group. Therefore, early operative treatment could be considered in cases of symptomatic ANS especially for athletes. Level III, retrospective comparative case series. © The Author(s) 2016.

    US women, including female athletes, are under ever increasing pressure to be thin ar thinner. this pressure to achieve and maintain a low body weight leads to potentially harmful patterns of long-term dieting or disordered eating, which can affect long-term health. Some of the health consequences of long-term energy restriction in female athletes may include poor energy and nutrient intakes, poor nutritional status, decreased RMR and total daily energy expenditure, increased psychological stress and risk for a clinical eating disorder, and increased risk for exercise-induced amenorrhea and osteoporosis. Female athletes participating in thin-build sports may be at risk for the disorders of the female athlete triad: disordered eating, amenorrhea, and osteoporosis. This triad of disorders can also produce severe health consequences that can influence present and future health. Strategies for helping active women get off the dieting "bandwagon" requires the identification of an appropriate and healthy body weight, good eating and exercise habits, and techniques for maintaining these habits throughout life.

Cross-sectional study. A university in Osaka, the largest city in western Japan. 232 female collegiate athletes. Premenstrual symptoms and social activities. The prevalence of each premenstrual symptom was high. The prevalence of moderate to severe PMS and PMDD was 8.6% and 2.9%, respectively, the same as in general high school students. The athletic performance of 44.3% of athletes was found to suffer in a game or in practice. "Elite athletes" (OR 8.63, 95% CI: 1.22-120.0), "Difficulty concentrating" (OR 3.15, 95% CI: 1.05-10.6), and "Fatigue or lack of energy" (OR 5.92, 95% CI: 1.32-34.5) increased the risk of poor athletic performance. This study showed that premenstrual symptoms affect not only the daily activities but also the athletic performance of collegiate athletes.

    The purpose of this study was to investigate the influence of personality on Premenstrual Syndrome (PMS) in athletes. The sample included 25 Brazilian athletes, between 18 and 49 years of age. A diary of PMS symptoms was used (based on the criteria from the American College of Obstetricians and Gynecologist, ACOG, 2000) and the Factorial Personality Inventory (Pasquali, Azevedo, & Ghesti, 1997). The Fisher exact test was used for data analysis, with p < .05. The athletes with PMS showed a strong need for performance, low need for assistance and introversión and very low need for change, while athletes without PMS demonstrated a very strong need for denial and strong needs for assistance, dominance, and persistence. There was a significant association between low denial (not submitting passively to external forces) and PMS (p < .05). It was concluded that certain personality traits may predispose athletes to react more intensely to needs and pressures produced by changes caused by the menstrual cycle, contributing to the onset of PMS.

    OBJECTIVE Sport-related concussion (SRC) has emerged as a public health problem, especially among student-athletes. Whereas most concussions resolve by 2 weeks, a minority of patients experience postconcussion syndrome (PCS), in which symptoms persist for months. The objective of this study was to elucidate factors predictive of PCS among a sample of National Collegiate Athletic Association (NCAA) student-athletes in the academic years 2009-2010 to 2014-2015. METHODS The SRC data originated from the NCAA Injury Surveillance Program (ISP) in the 2009-2010 to 2014-2015 academic seasons. The NCAA ISP is a prospective database made up of a convenience sample of schools across all divisions. All SRCs are reported by certified athletic trainers. The PCS group consisted of concussed student-athletes with concussion-related symptoms that lasted ≥ 4 weeks. The non-PCS group consisted of concussed student-athletes with symptom resolution in ≤ 2 weeks. Those with symptoms that resolved in the intermediate area of 2-4 weeks were excluded. Odds ratios (ORs) were estimated using logistic regression. RESULTS During the 2009-2010 to 2014-2015 seasons, 1507 NCAA student-athletes sustained an SRC, 112 (7.4%) of whom developed PCS (i.e., concussion-related symptoms that lasted ≥ 4 weeks). Men's ice hockey contributed the largest proportion of concussions to the PCS group (28.6%), whereas men's football contributed the largest proportion of concussions in the non-PCS group (38.6%). In multivariate analysis, recurrent concussion was associated with increased odds of PCS (OR 2.08, 95% CI 1.28-3.36). Concussion symptoms that were also associated with increased odds of PCS included retrograde amnesia (OR 2.75, 95% CI 1.34-5.64), difficulty concentrating (OR 2.35, 95% CI 1.23-4.50), sensitivity to light (OR 1.97, 95% CI 1.09-3.57), and insomnia (OR 2.19, 95% CI 1.30-3.68). Contact level, sex, and loss of consciousness were not associated with PCS. CONCLUSIONS Postconcussion syndrome

    Historically, athletic hip injuries have garnered little attention; however, these injuries account for approximately 6% of all sports injuries and their prevalence is increasing. At times, the diagnosis and management of hip injuries can be challenging and elusive for the team physician. Hip injuries are seen in high-level athletes who participate in cutting and pivoting sports that require rapid acceleration and deceleration. Described previously as the "sports hip triad," these injuries consist of adductor strains, osteitis pubis, athletic pubalgia, or core muscle injury, often with underlying range-of-motion limitations secondary to femoroacetabular impingement. These disorders can happen in isolation but frequently occur in combination. To add to the diagnostic challenge, numerous intra-articular disorders and extra-articular soft-tissue restraints about the hip can serve as pain generators, in addition to referred pain from the lumbar spine, bowel, bladder, and reproductive organs. Athletic hip conditions can be debilitating and often require a timely diagnosis to provide appropriate intervention.

    Context: The female athlete triad describes the interrelatedness of energy availability, menstrual function, and bone density. Although associations between triad components and musculoskeletal injury (INJ) have been reported in collegiate athletes, limited information exists about menstrual irregularity (MI) and INJ in the high school population. Objective: To determine the prevalence of and relationship between MI and INJ in high school athletes. Design: Cross-sectional study. Setting: High schools. Patients or Other Participants: The sample consisted of 249 female athletes from 3 high schools who competed in 33 interscholastic, school-sponsored sport teams, dance teams, and cheerleading or pom-pon squad during the 2006–2007 school year. Each athlete remained on the roster throughout the season. Main Outcome Measure(s): Participants completed a survey regarding injury type, number of days of sport participation missed, and menstrual history in the past year. Results: The prevalences of MI and INJ were 19.7% and 63.1%, respectively. Athletes who reported MI sustained a higher percentage of severe injuries (missing ≥22 days of practice or competition) than did athletes who reported normal menses. Although the trend was not significant, athletes with MI were almost 3 times more likely to sustain an injury resulting in 7 or more days of time lost from sport (odds ratio = 2.7, 95% confidence interval = 0.8, 8.8) than those who sustained an injury resulting in 7 or fewer days of time lost. Conclusions: The incidences of MI and INJ in this high school population during the study period were high. Athletes who reported MI sustained a higher percentage of severe injuries than did athletes who reported normal menses. Education programs to increase knowledge and improve management of MI and its potential effects on injury in female high school athletes are warranted. PMID:22488233

    Female athletes are at least as at risk as other women for eating disorders (EDs) and at risk for the female athlete triad (i.e., inadequate energy availability, menstrual disorders, and osteoporosis). This study investigated whether two evidence-based programs appear promising for future study if modified to address the unique needs of female athletes. Athletes were randomly assigned to athlete-modified dissonance prevention or healthy weight intervention (AM-HWI). ED risk factors were assessed pre/post-treatment, and 6-week and 1-year follow-up. Results (analyzed sample N = 157) indicated that both interventions reduced thin-ideal internalization, dietary restraint, bulimic pathology, shape and weight concern, and negative affect at 6 weeks, and bulimic pathology, shape concern, and negative affect at 1 year. Unexpectedly we observed an increase in students spontaneously seeking medical consultation for the triad. Qualitative results suggested that AM-HWI may be more preferred by athletes. PMID:22019502

    Context: As the number of female college students participating in athletics has grown dramatically in the last few decades, sports medicine health care providers have become more aware of the unique health concerns of athletic women. These concerns include disordered eating, amenorrhea, and osteoporosis: the female athlete triad. Disordered eating appears to be central in the triad, and the literature has conflicting data regarding the influence of athletic participation on disordered-eating behaviors. Objective: To compare disordered-eating symptoms between collegiate athletes (in lean and non-lean sports) and nonathletes. Design: A volunteer, cross-sectional cohort study of female students during the 2002–2003 academic year. Setting: A National Collegiate Athletic Association Division I institution. Patients or Other Participants: Undergraduate females, including 84 collegiate athletes and 62 nonathletes. Main Outcome Measure(s): Symptoms associated with disordered eating were assessed using the Eating Disorders Inventory-2, a self-report measure of 91 items, and self-reported weight and menstrual function. Results: The athletes had significantly lower scores in body dissatisfaction (P = .01) and ineffectiveness (P = .002). No difference in mean body weight was noted between the 2 groups, but the nonathlete group had a significantly lower desired body weight (P = .004). Lean-sport athletes had a higher score on body dissatisfaction (P = .008) and lower actual (P = .024) and desired body weight (P = .002) than non–lean-sport athletes. A total of 7.1% of the collegiate athletes and 12.9% of the nonathletes were classified as having a high risk for disordered eating. Within the athlete sample, the high-risk group included 2.9% of the non–lean-sport athletes and 25% of the lean-sport athletes. Conclusions: In our study, female athletes did not exhibit more disordered-eating symptoms than women who did not participate in collegiate sports. However, our data

    The cumulative effect of the female athlete triad (Triad) risk factors on the likelihood of low bone mineral density (BMD) in exercising women is unclear. This study aimed to determine the risk of low BMD in exercising women with multiple Triad risk factors. We retrospectively examined cross-sectional data from 437 exercising women (mean ± SD age of 18.0 ± 3.5 yr, weighed 57.5 ± 7.1 kg with 24.5% ± 6.1% body fat) obtained at baseline from 4 prospective cohort studies examining Triad risk factors. Questionnaires were completed to obtain information on demographic characteristics, self-reported eating attitudes/behaviors, menstrual function, sport/activity participation, and medication use. Height and body weight were measured. BMD was measured using dual energy x-ray absorptiometry. Low BMD was defined as z-scores of <-1 and ≤-2. Chi-square tests were performed to determine the percentage of women with low BMD who met the criteria for individual (current oligo/amenorrhea, late menarche, low body mass index (BMI), elevated dietary restraint, lean sport/activity participation) or multiple (2, 3, 4, or 5) Triad risk factors. Late menarche and low BMI were associated with the highest percentage of low BMD (z-score < -1), 55% and 54%, respectively, and low BMD (z-score ≤-2), 14% and 16%, respectively. The percentage of participants with low BMD (z-score < -1 and ≤-2) increased from 10% to 62% and from 2% to 18%, respectively, as women met the criteria for an increasing number of Triad risk factors. A cumulative number of Triad risk factors were associated with an increased risk of low BMD, suggesting a dose-response association between the number of Triad risk factors and BMD in exercising women. Further research should be conducted to develop a user-friendly algorithm integrating these indicators of risk for low BMD in exercising women (particularly factors associated with low BMI/body weight, menstrual dysfunction, lean sport/activity participation, and

    Persons with Down syndrome are well known to have a high prevalence of vision and eye health problems, many of which are undetected or untreated primarily because of infrequent ocular examinations. Public screening programs, directed toward the pediatric population, have become more popular and commonly use letter or symbol charts. This study compares 2 vision screening methods, the Lea Symbol chart and a newly developed interactive computer program, the Vimetrics Central Vision Analyzer (CVA), in their ability to identify ocular disease in the Down syndrome population. Athletes with Down syndrome participating in the European Special Olympics underwent an ocular screening including history, auto-refraction, colour vision assessment, stereopsis assessment, motility assessment, pupil reactivity, and tonometry testing, as well as anterior segment and fundus examinations to evaluate for ocular disease. Visual acuity was tested with the Lea chart and CVA to evaluate these as screening tests for detecting ocular disease as well as significant, uncorrected refractive errors. Among the 91 athletes that presented to the screening, 79 (158 eyes) were sufficiently cooperative for the examination to be completed. Mean age was 26 years +/-10.8 SD. Significant, uncorrected refractive errors (>/=1.00 spherical equivalent) were detected in 28 (18%) eyes and ocular pathology in 51 (32%) eyes. The Lea chart sensitivity and specificity were 43% and 74%, respectively, for detecting ocular pathology and 58% and 100% for detecting uncorrected refractive errors. The CVA sensitivity and specificity were 70% and 86% for detecting pathology and 71% and 100% for detecting uncorrected refractive errors. This study confirmed the findings of prior studies in identifying a significant presence of uncorrected refractive errors and ocular pathology in the Down syndrome population. Screening with the Lea symbol chart found borderline sufficient sensitivity and specificity for the test to be used

    To determine whether professional and amateur athletes showed differences in ankle function when treated with endoscopic technique for posterior ankle impingement syndrome, to verify the impact of the presence of associated lesions in clinical evolution and to assess time to return to sport (we hypothesize that time will be the only difference between groups). Thirty-two athletes with a diagnosis of posterior impingement syndrome underwent surgery endoscopically. The American Orthopaedics Foot and Ankle Society (AOFAS) scale was used to compare functional results between amateur (15) and professional athletes (17). The satisfaction, time to return to sport, operative time, intraoperative findings and complications were evaluated, and the presence of associated injuries interfering in these results was verified. The preoperative AOFAS score range for the professional group was 62.9 ± 14 preoperatively and 92.3 ± 7.7 postoperatively, and for the amateur group was 67.9 ± 19.7 and 94 ± 9.3. The satisfaction was excellent or good in 94 % of all cases and fair in 6%. The average time of surgery was 48.3 + 25 min. Bone involvement was present in 100% of cases and complications in three cases. Time to return to sports was similar (n.s.) in both groups, and the mean time was 15.6 ± 13.7 and 16.3 ± 9 weeks, respectively. No significant difference regarding functional results and time to return to sports between professionals and amateur athletes operated was found. Athletes showed mainly good and excellent results and low complication rate. The presence of associated injuries did not significantly influence the results. With these results, the high-level athlete can better programme their surgeries so they can fully recover and perform better in the most important competitions. Level III.

  15. Athletes: Fit but Unhealthy?

    PubMed

    Maffetone, Philip B; Laursen, Paul B

    While the words "fit" and "healthy" are often used synonymously in everyday language, the terms have entirely separate meanings. Fitness describes the ability to perform a given exercise task, and health explains a person's state of well-being, where physiological systems work in harmony. Although we typically view athletes as fit and healthy, they often are not. The global term we place on unhealthy athletes is the overtraining syndrome. In this current opinion, we propose that two primary drivers may contribute to the development of the overtraining syndrome, namely high training intensity and the modern-day highly processed, high glycemic diet. Both factors elicit a sympathetic response through the hypothalamic-pituitary-adrenal axis, in turn driving systemic reactive oxygen species production, inflammation, and a metabolic substrate imbalance towards carbohydrate and away from fat oxidation, manifesting in an array of symptoms often labeled as the overtraining syndrome. Ultimately, these symptoms reveal an unhealthy athlete. We argue that practitioners, scientists, and athletes may work towards health and alleviate overtraining syndrome by lowering training intensity and removing processed and/or high glycemic foods from the diet, which together enhance fat oxidation rates. Athletes should be fit and healthy.

    To describe a clinical treatment algorithm for posterior ankle impingement (PAI) syndrome in professional football players. A case series of 26 elite professional football players diagnosed and treated for posterior ankle impingement syndrome were included for the study. All of the athletes received conservative treatment with physical therapy modalities initially. If the first line medical treatment and rehabilitation was ineffective to alleviate the symptoms, ultrasound-guided corticosteroid injection was proposed and thereafter the patients underwent posterior ankle arthroscopy if the complaints are still unresolved. The pain scores (AOFAS, VAS), and time to return to play were the main outcome measures. The complaints of 18 (69.2%) players were subsided with non-surgical treatment whereas three of acute cases and five of the chronic cases did not respond to medical treatment and arthroscopic surgery was performed for eight athletes. Eighteen players returned to training for a mean time of 36.3 days (24-42 days) after conservative treatment. The patients who underwent arthroscopic surgery returned to training for a mean time of 49.8 days (42-56 days) after the surgery. All athletes returned to their previous level of competition after treatment without any complications or recurrence in a mean follow-up 36.5 months (19-77 months). Non-surgical treatment modalities were effective in 2/3 of posterior ankle impingement syndrome in elite football players. On the other hand, posterior ankle arthroscopy is safe and effective treatment option for posterior ankle impingement syndrome if the conservative treatment fails. Level IV, Therapeutic study.

    2015-01-01

    Abstract Infants with the triad (neurologic dysfunction, subdural hematoma [SDH], and retinal hemorrhage) are often diagnosed as victims of shaken baby syndrome. Medical conditions/predisposing factors to developing the triad are often dismissed: short falls, birth-related SDH that enlarges, macrocephaly, sinus/cortical vein thrombosis, and others. Six infants with the triad are described in which child abuse was diagnosed, but parents denied wrongdoing. All 6 had either macrocephaly or enlarging head circumference, which suggested medical explanations. Three infants incurred short falls, 1 had a difficult delivery in which there was likely a rebleed of a birth-related SDH, 1 had a spontaneous SDH associated with increased extra-axial fluid spaces, and 1 had a sinus thrombosis. Following legal proceedings, all 6 infants were returned to their parents, and there has been no child maltreatment in follow-up, suggesting child abuse never happened. The results indicate that alternative medical explanations for causing the triad should be considered and that macrocephaly or an enlarging head circumference raises the possibility of a medical explanation.

    Premenstrual syndrome (PMS) is psychosomatic disorder that are limited to the late luteal phase in the menstrual cycle. PMS could impair athletic performance. To investigate associations between proportions of dietary plant and animal protein and PMS-related impairment of athletic performance, we surveyed 135 female athletes aged 18-23 years attending Kindai University. Participants belonged to authorized university clubs, all of which have high rankings in Japanese university sports. Participants completed self-administered questionnaires on diet history, demographics, and PMS-related impairment of athletic performance. Total protein, animal protein, and plant protein intake were examined, and the proportion of dietary plant protein was calculated for each participant. We divided athletes into two groups: those without PMS-related impairment of athletic performance (n = 117) and those with PMS-related performance impairment (n = 18). A t-test was used to compare mean values and multivariable adjusted mean values between groups; adjustment variables were energy intake, body mass index, and daily training duration. Total protein intake was not significantly different between the groups. However, athletes whose performance was affected by PMS reported higher intake of animal protein (mean 50.6 g) than athletes whose performance was unaffected by PMS (mean 34.9 g). Plant protein intake was lower among athletes with PMS-related impairment (mean 25.4 g) than among athletes without impairment (mean 26.9 g). The proportion of dietary plant protein was lower among athletes with PMS-related impairment (39.3%) than those without impairment (45.9%). A low proportion of dietary plant protein may cause PMS-related athletic impairment among athletes.

    A geometric model of formation of surfaces comprising an interconnected triple of emitter, reflector and receiver is presented in the paper. The model is based on cyclographic mapping of a spatial curve to the plane. In such map any given point (x, y, z) of the curve corresponds to a cycle with center (x, y) and radius equal to z applicate. The entire curve corresponds to a directed envelope of cycles consisting, in the general case, of two branches. It is shown that the triad of curves consisting of two branches of the envelope and the orthogonal projection of the original curve within the plane (xy) corresponds to a triad of developable surfaces. The triad of curves in the plane (xy) and the original curve together form a triad of ruled surfaces. Both triads have an optical property. Any ray of light emerging from the point of the emitter surface along the normal to it and falling on the surface of the reflector afterwards is directed along the normal vector to the surface of the receiver. The direct and inverse problems of formation of the triad of surfaces are solved. In the first case, a one-parameter set of triads of surfaces is defined from a given spatial curve. In the second case, a single triad of surfaces is defined from a pair of curves "emitter-receiver" defined on the plane (xy). Numerical examples of solutions of the direct and inverse problems are considered and the corresponding visualizations are given. The results of the work can be used in the design of reflector antennas in radar systems and systems for converting solar energy into electric and thermal energy.

    Athletic pubalgia or sports hernia is a syndrome of chronic lower abdomen and groin pain that may occur in athletes and nonathletes. Because the differential diagnosis of chronic lower abdomen and groin pain is so broad, only a small number of patients with chronic lower abdomen and groin pain fulfill the diagnostic criteria of athletic pubalgia (sports hernia). The literature published to date regarding the cause, pathogenesis, diagnosis, and treatment of sports hernias is confusing. This article summarizes the current information and our present approach to this chronic lower abdomen and groin pain syndrome. Copyright © 2011 Elsevier Inc. All rights reserved.

    To determine the specific characteristics of premenstrual syndrome (PMS)/premenstrual dysphoric disorder (PMDD) in Japanese collegiate athletes, with a focus on their fish consumption. Cross-sectional study. A university in Osaka, the largest city in western Japan. The participants were 312 female collegiate students. The study group was composed of 200 students who were members of sport clubs, and the control (nonathletes) group was composed of 112 members of cultural clubs. Premenstrual symptoms and social activities. The prevalence of moderate to severe PMS and PMDD in the study group was the same as in nonathletes. The prominent feature of premenstrual symptoms in athletes was that the severities of 'physical symptoms' and 'performance in training or competition' were much greater than those of nonathletes (P = .003 and P = .002, Mann-Whitney U test). There was a greater effect of PMS and PMDD on athletes, affecting their physical symptoms and performance compared with nonathletes. In terms of dietary habits, 'fish or dried fish' consumption was associated with a decreased risk of poor performance in athletes (odds ratio, 0.61; 95% confidence interval, 0.40-0.92). The results from this study indicate that fish consumption might be positively associated with the relief of PMS/PMDD-induced athletic disturbance.

    To investigate the relationship between the occurrence of stress fracture and premenstrual syndrome (PMS)/premenstrual dysphoric disorder (PMDD) in Japanese adolescent athletes. Cross-sectional study. Osaka, Japan. A school-based survey on menstruation and school life was conducted using a sample of 1818 Japanese female students who belonged to two public high schools in Japan. Among them, we recruited 394 athletes who had regular menstrual cycles (25-38 days) and completed a questionnaire about their premenstrual symptoms and their competitive career. Premenstrual symptoms and the occurrence of stress fracture. The prevalences of moderate-to-severe PMS and PMDD were 8.9% and 1.3%, respectively, which were the same as in collegiate athletes in a previous study. Premenstrual symptoms disturbed 'Work efficiency or productivity, home responsibilities', 'Relationships with coworkers or family' and 'Athletic performance in training or competition' more severely than menstrual pain (p=0.031, p=0.004 and p<0.001, respectively). 66 athletes (16.8%) reported having experienced a stress fracture. The severity of 'Overeating or food cravings', 'Physical symptoms' and 'Performance in training or competition' in athletes with previous stress fractures were much higher than in those without a history of stress fractures (p=0.015, p=0.008 and p=0.006, respectively). In terms of premenstrual symptoms, 'Physical symptoms' was associated with an increased risk of stress fractures in athletes (OR 1.66, 95% CI 1.06 to 2.62). The results from this study indicated that premenstrual symptoms may affect athletic performance and has the risk of stress fractures in adolescent athletes.

    The most common clinical syndromes presenting with paragangliomas and/or pheochromocytomas as their endocrine components are multiple endocrine neoplasia type 2, neurofibromatosis, Von Hippel-Lindau syndrome, Carney-Stratakis syndrome, Carney triad, and the recently described hereditary paraganglioma syndrome. Only Carney triad is known to also present with adrenocortical adenomas, currently representing the only described syndrome in which all 3 of the aforementioned tumors are found together. In most cases, prototypical lesions of the triad such as gastrointestinal stromal tumor and pulmonary chondromas are also seen. We present a case of a young woman with synchronous paragangliomas, adrenal/extra-adrenal cortical neoplasms, and pheochromocytoma without genetic mutations for multiple endocrine neoplasia 2, Von Hippel-Lindau syndrome, neurofibromatosis, and succinate dehydrogenase. We speculate that this represents a previously undescribed presentation of Carney triad and, at the very least, indicates the need for monitoring for the development of other tumors of the triad.

    Background The only three randomized trials on the treatment of MTSS were all performed in military populations. The treatment options investigated in this study were not previously examined in athletes. This study investigated if functional outcome of three common treatment options for medial tibial stress syndrome (MTSS) in athletes in a non-military setting was the same. Methods The study design was randomized and multi-centered. Physical therapists and sports physicians referred athletes with MTSS to the hospital for inclusion. 81 athletes were assessed for eligibility of which 74 athletes were included and randomized to three treatment groups. Group one performed a graded running program, group two performed a graded running program with additional stretching and strengthening exercises for the calves, while group three performed a graded running program with an additional sports compression stocking. The primary outcome measure was: time to complete a running program (able to run 18 minutes with high intensity) and secondary outcome was: general satisfaction with treatment. Results 74 Athletes were randomized and included of which 14 did not complete the study due a lack of progress (18.9%). The data was analyzed on an intention-to-treat basis. Time to complete a running program and general satisfaction with the treatment were not significantly different between the three treatment groups. Conclusion This was the first randomized trial on the treatment of MTSS in athletes in a non-military setting. No differences were found between the groups for the time to complete a running program.

    AIM: To analyze stress fractures in athletes based on experience from our sports medicine clinic. METHODS: We investigated the association between stress fractures and age, sex, sports level, sports activity, and skeletal site in athletes seen at our sports medicine clinic between September 1991 and April 2009. Stress fractures of the pars interarticularis were excluded from this analysis. RESULTS: During this period (18 years and 8 mo), 14276 patients (9215 males and 5061 females) consulted our clinic because of sports-related injuries, and 263 patients (1.8%) [171 males (1.9%) and 92 females (1.8%)] sustained stress fractures. The average age of the patients with stress fractures was 20.2 years (range 10-46 years); 112 patients (42.6%) were 15-19 years of age and 90 (34.2%) were 20-24 years of age. Altogether, 90 patients (34.2%) were active at a high recreational level and 173 (65.8%) at a competitive level. The highest proportion of stress fractures was seen in basketball athletes (21.3%), followed by baseball (13.7%), track and field (11.4%), rowing (9.5%), soccer (8.4%), aerobics (5.3%), and classical ballet (4.9%). The most common sites of stress fractures in these patients were the tibia (44.1%), followed by the rib (14.1%), metatarsal bone (12.9%), ulnar olecranon (8.7%) and pelvis (8.4%). The sites of the stress fractures varied from sport to sport. The ulnar olecranon was the most common stress fracture site in baseball players, and the rib was the most common in rowers. Basketball and classical ballet athletes predominantly sustained stress fractures of the tibia and metatarsal bone. Track and field and soccer athletes predominantly sustained stress fractures of the tibia and pubic bone. Aerobics athletes predominantly sustained stress fractures of the tibia. Middle and long distance female runners who sustained multiple stress fractures had the female athlete triad. CONCLUSION: The results of this analysis showed that stress fractures were seen in high

    Female participation in high school athletics has increased 800% in the last 30 years. The problem of exercise-induced amenorrhea was initially thought to be analogous to hypoestrogenism, but recent studies suggest that nutritional issues underlie most of the pathophysiology and that the mechanism is different from that seen in the primary hypogonadal state. Exercise-induced amenorrhea can be an indicator of an energy drain, and the presence of the other components of the female athlete triad-bone density loss and eating disorders-must be determined as well. Addressing skeletal problems related to nutritional and hormonal deficiencies in this population is of very high priority.

    Context: Chronic lower leg pain in athletes can be a frustrating problem for patients and a difficult diagnosis for clinicians. Myriad approaches have been suggested to evaluate these conditions. With the continued evolution of diagnostic studies, evidence-based guidance for a standard approach is unfortunately sparse. Evidence Acquisition: PubMed was searched from January 1980 to May 2011 to identify publications regarding chronic lower leg pain in athletes (excluding conditions related to the foot), including differential diagnosis, clinical presentation, physical examination, history, diagnostic workup, and treatment. Results: Leg pain in athletes can be caused by many conditions, with the most frequent being medial tibial stress syndrome; chronic exertional compartment syndrome, stress fracture, nerve entrapment, and popliteal artery entrapment syndrome are also considerations. Conservative management is the mainstay of care for the majority of causes of chronic lower leg pain; however, surgical intervention may be necessary. Conclusion: Chronic lower extremity pain in athletes includes a wide differential and can pose diagnostic dilemmas for clinicians. PMID:23016078

    Austrian syndrome is a rare medical condition characterised by the triad of pneumonia, meningitis and endocarditis due to Streptococcus pneumoniae Native aortic valve insufficiency is the most common cause of cardiac failure in these patients, requiring valve replacement. We report a 52-year-old chronic alcoholic man who presented with fever, neck rigidity and loss of c onsciousness. Lumbar puncture revealed central nervous system infection while chest X-ray showed pneumonia. Blood and cerebrospinal fluid cultures revealed S. pneumonia Transoesophageal echocardiography revealed aortic endocarditis with severe valve insufficiency. The patient underwent aortic valve replacement and was finally discharged after completion of 6 weeks intravenous antibiotic treatment. Nowadays, Austrian syndrome is seen infrequently in the antibiotic era. However, clinicians should be aware of this syndrome as its early recognition and prompt combined medical and surgical treatment could reduce morbidity and mortality due to this potentially catastrophic clinical entity. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    We present a rare case of bilateral crocodile tears syndrome (CTS) in the course of Melkersson-Rosenthal syndrome. Melkersson-Rosenthal syndrome is characterised by a triad of recurrent orofacial swelling, relapsing facial paralysis, and fissured tongue. The classic triad is infrequent and oligosymptomatic variants are seen more frequently. CTS is a rare complication of facial nerve paralysis characterised by inappropriate lacrimation on the side of the palsy in response to salivary stimuli. It results from aberrant reinnervation of the lacrimal gland by salivary parasympathetic fibres. The therapeutic approach for an acute bout of Melkersson-Rosenthal syndrome consists mainly of steroid administration. CTS management is composed of anticholinergic drugs and surgical procedures. Botulin toxin injection into the lacrimal gland is the most modern therapeutic option. In the case presented CTS developed in a 50-year-old man after 5 incidents of facial palsy due to Melkersson-Rosenthal syndrome. The case deserves attention due to the rarity of the observed symptoms and signs.

    The metabolic triad [fasting insulin, apolipoprotein B, and low-density lipoporotein (LDL) peak particle density] is characteristic of increased intra-abdominal adipose tissue and insulin resistance and can be predicted by the simple and adoptable screening tool, the hypertriglyceridemic waist. The associations between hypertriglyceridemic waist components [fasting triglycerides (TG) and waist circumference cut-points derived from a child-specific metabolic syndrome definition] with the metabolic triad were examined in obese youth before and after weight loss. A continuous metabolic triad score (MTS) was calculated as a cumulative and standardized residual score of fasting insulin, apolipoprotein B, and LDL peak particle density (z-scores of the metabolic triad variables regressed onto age and sex). The predictive ability of TG and waist in assessing metabolic triad change was undertaken in 75 clinically obese boys and girls, aged 8-18, body mass index (BMI) 34.2±6.4 kg/m(2) before and after weight loss. Fasting TG concentrations (r(2)=0.216, P<0.0001) and waist circumference (r(2)=0.049, P=0.019) were both significant independent predictors of the cumulative MTS, together accounting for 26.5% of its total variance. All cardiometabolic risk factors [except a reduction in high-density lipoprotein cholesterol (HDL-C)] were favorably modified following weight loss. Fasting TG change was the only significant predictor of the MTS change (r(2)=0.177, P<0.0001). Waist circumference was not a significant predictor of MTS change. The reduction in fasting TG concentration (but not waist circumference) was the only significant predictor of MTS change. Fasting TG may be the most important metabolic syndrome component to best characterize the metabolic heterogeneity in obese cohorts and the changes in metabolic risk in clinically obese youth.

    The frequency and nature of exertion pains of the leg in athletes were studied in 2,750 cases of overuse injuries treated at the Sports Clinic of the Deaconess Institute of Oulu, Finland, during the years 1972-1977. 465 cases of exertion pain (18%) were located in the shin. The medial tibial syndrome was the most common overuse injury among these athletes, comprising 9.5% of all exertion injuries and 60% of the leg exertion pains. Together with stress fracture of the tibia, the second most common exertion pain of the leg, it accounted for 75% of the total leg pains. There are certain difficulties in differentiating between the medial tibial syndrome and stress fracture of the tibia. They both occur at the same site with similar symptoms. Radiological examination and isotope scanning are needed. The medial tibial syndrome is an overuse injury at the medial tibial border caused by running exercises. The pain is elicited by exertional ischaemia. The pathogenesis is explained by increased pressure in the fascial compartment of the deep flexor muscles due to prolonged exercise. Similar chronic ischaemic pains from exercise are also found in other fascial compartments of the leg, especially in the anterior compartment. The only treatment needed for stress fractures is rest from training. Fascial compartment pains also usually subside. If chronic fascial syndromes prevent training, fasciotomy is recommended as a reliable method to restore the athlete to normal training without pains. PMID:486888

    Carney triad is a very rare syndrome characterized by the synchronous or metachronous occurrence of gastrointestinal stromal tumors, pulmonary chondroma, and extra-adrenal paraganglioma. We present the case of a 36-year-old woman with complete Carney triad who underwent a Ga-DOTA-TATE PET/CT scan for restaging of metastasizing extra-adrenal paraganglioma and for evaluation of targeted radionuclide therapy potential. On the Ga-DOTA-TATE PET scan, increased tracer accumulation was observed in paraganglioma metastases. This case highlights the usefulness of Ga-DOTA-TATE PET/CT for restaging of metastasizing paraganglioma in Carney triad and the option of targeted radionuclide therapy in this entity.

    Objective To determine bone mineral density (BMD) and the associations among BMD, menstrual history, disordered eating (DE), training history, intentional weight loss (IWL) and rib pain for the first time in female lightweight rowers. Setting 9 lightweight rowing clubs, UK. Participants 29 Caucasian female lightweight rowers volunteered. 21 (12 active, 9 retired) completed the study. Inclusion criteria: female lightweight rowers aged over 18 years. Exclusion criteria: participants with a history of bone disease, used medications known to influence BMD or if they were pregnant, lactating or postmenopausal. Main outcome measures Dual-energy X-ray absorptiometry measured total body (TB) composition and BMD at the spine, femoral neck (FN), radius and TB. DE, oligomenorrhoea/amenorrhoea years; rib pain and training history. Results DE was reported in six of the rowers. The active with DE started rowing younger (p<0.05) than those without, and their amount of IWL was associated with Eating Attitudes Test-26 score (p<0.05). Some participants reported a history of oligomenorrhoea/amenorrhoea 17 (76%) and/or rib pain 7 (32%) with those with rib pain having lower spine and TB Z-scores (p<0.05) than those without. Those with oligomenorrhoea/amenorrhoea had lower spine Z-scores (p<0.01) than those without. Twelve participants had low BMD; three at spine; one at FN; and eight at radius. Thirteen per cent of mean total training hours (18.6±9.1 h/week) were spent strength training (2.4±2.2 h/week). Conclusions Upper body exercises incorporating multidimensional high peak bone strain were not reported and may need to be considered in their strength training to improve radial BMD. Results suggest IWL and high-level training at a young age increases the likelihood of DE and there may be a lack of quality nutritional support for these athletes. Thus, multidisciplinary sport science support should be offered at a young age and perhaps also to consider changing the weight rules

    Various tibial dimensions and geometric parameters have been linked to stress fractures in athletes and military recruits, but many mechanical parameters have still not been investigated. Sedentary people, athletes with medial tibial stress syndrome, and athletes with stress fractures have smaller tibial geometric dimensions and parameters than do uninjured athletes. Cohort study; Level of evidence, 3. Using a total of 88 subjects, male and female patients with either a tibial stress fracture or medial tibial stress syndrome were compared with both uninjured aerobically active controls and uninjured sedentary controls. Tibial scout radiographs and cross-sectional computed tomography images of all subjects were scanned at the junction of the midthird and distal third of the tibia. Tibial dimensions were measured directly from the films; other parameters were calculated numerically. Uninjured exercising men have a greater tibial cortical cross-sectional area than do their sedentary and injured counterparts, resulting in a greater value of some other cross-sectional geometric parameters, particularly the section modulus. However, for women, the cross-sectional areas are either not different or only marginally different, and there are few tibial dimensions or geometric parameters that distinguish the uninjured exercisers from the sedentary and injured subjects. In women, the main difference between the groups was the distribution of cortical bone about the centroid as a result of the different values of section modulus. Last, medial tibial stress syndrome subjects had smaller tibial cross-sectional dimensions than did their uninjured exercising counterparts, suggesting that medial tibial stress syndrome is not just a soft-tissue injury but also a bony injury. The results show that in men, the cross-sectional area and the section modulus are the key parameters in the tibia to distinguish exercise and injury status, whereas for women, it is the section modulus only.

    Athletic pubalgia is a painful and complex syndrom encountered by athletes involved in pivoting and cutting sports such as hockey and soccer. To date, there is no real consensus on the criteria for a reliable diagnostic, the different investigations, and the appropriate therapy. Current literature underlines intrinsic and extrinsic factors contributing to athletic pubalgia. This review article reports upon two novelties related to the issue: the importance and efficience of prevention program and the association of femoro-acetabular impingement with the pubalgia.

  17. Triad Resonance in the Gravity-Acoustic Family

    2015-12-01

    Resonance interactions of waves play a prominent role in energy share among the different wave types involved. Such interactions may significantly contribute, among others, to the evolution of the ocean energy spectrum by exchanging energy between surface-gravity waves; surface and internal gravity waves; or even surface and compression-type waves, that can transfer energy from the upper ocean through the whole water column reaching down to the seafloor. A resonant triad occurs among a triplet of waves, usually involving interaction of nonlinear terms of second order perturbed equations. Until recently, it has been believed that in a homogeneous fluid a resonant triad is possible only when tension forces are included, or at the limit of a shallow water, and that when the compressibility of water is considered, no resonant triads can occur within the family of gravity-acoustic waves. However, more recently it has been proved that, under some circumstances, resonant triads comprising two opposing surface-gravity waves of similar periods (though not identical) and a much longer acoustic-gravity wave, of almost double the frequency, exist [Kadri and Stiassnie 2013, J. Fluid Mech.735 R6]. Here, I report on a new resonant triad involving a gravity wave and two acoustic waves of almost double the length. Interestingly, the two acoustic waves propagate in the same direction with similar wavelengths, that are almost double of that of the gravity wave. The evolution of the wave triad amplitudes is periodic and it is derived analytically, in terms of Jacobian elliptic functions and elliptic integrals. The physical importance of this type of triad interactions is the modulation of pertinent acoustic signals, leading to inaccurate signal perceptions. Enclosed figure: presents an example spatio-temporal evolution of the wave triad amplitudes. The gravity wave (top) remains almost unaltered, while the envelope slowly displaces to the left. However, the prescribed acoustic

    Objective To propose the inclusion of a gynecological investigation during the evaluation of athletes before competitions, using a specific instrument called the Pre-participation Gynecological Examination (PPGE). Methods The study assessed 148 athletes, mean age of 15.4±2.0 years, who engaged in eight different sports modalities, and who responded to a questionnaire named Pre-Participation Gynecological Examination (PPGE), to the International Consultation on Incontinence Questionnaire - Short Form (for urinary loss), and to the Eating Attitudes Test (for eating disorders). Results Fifty percent of the participants reported irregular menstrual intervals, 23.0% did not know about sexually transmitted diseases, and 72.4% denied having, at least, an annual gynecological appointment. The study identified 18.2% who had urinary loss, and 15% presented with an increased risk of eating disorders. Moreover, 89.9% were not familiar with the occurrence of urinary incontinence in athletes and did not know that they were susceptible to the female athlete triad. A total of 87.1% of them stated that would not mention these issues to their coaches even if this would improve their health or performance. Conclusion The Pre-Participation Gynecological Examination can be considered an easy-to-apply instrument that allowed the diagnosis of alterations often underestimated by the athletes themselves. After its application, the alterations were identified, and determined the athletes’ referral to appropriate evaluation and treatment. PMID:25628197

    2016-01-01

    Historically, patients with sports-related concussion (SRC) have been managed in a uniform fashion consisting mostly of prescribed physical and cognitive rest with the expectation that all symptoms will spontaneously resolve with time. Although this approach will result in successful return to school and sports activities in the majority of athletes, an important proportion will develop persistent concussion symptoms characteristic of post-concussion syndrome (PCS). Recent advances in exercise science, neuroimaging, and clinical research suggest that the clinical manifestations of PCS are mediated by unique pathophysiological processes that can be identified by features of the clinical history and physical examination as well as the use of graded aerobic treadmill testing. Athletes who develop PCS represent a unique population whose care must be individualized and must incorporate a rehabilitative strategy that promotes enhanced recovery of concussion-related symptoms while preventing physical deconditioning. In this review, we present our evolving evidence-based approach to evaluation and management of athletes with PCS that aims to identify the pathophysiological mechanisms mediating persistent concussion symptoms and guides the initiation of individually tailored rehabilitation programs that target these processes. In addition, we outline the important qualified roles that multi-disciplinary healthcare professionals can play in the management of this patient population, and discuss where future research efforts must be focused to further evaluate this evolving pathophysiological approach.

    High-school girls and collegiate women have tremendous opportunities to participate in athletic teams. Young girls are also playing in club and select teams at an early age and often, year-round. There are many benefits for participating in sport and physical activity on both the physical and mental health of girls and women. Decreased risk for heart disease and diabetes mellitus, along with improved self-esteem and body-image, were among the first reported benefits of regular physical activity. In addition, sport participation and physical activity is also associated with bone health. Athletes have a greater bone mineral density compared with non-active and physically active females. The increase in bone mass should reduce the risk of fragility fractures in later life. There appears to be a window of opportunity during the development of peak bone mass in which the bone is especially responsive to weight-bearing physical activity. Impact loading sports such as gymnastics, rugby or volleyball tend to produce a better overall osteogenic response than sports without impact loading such as cycling, rowing and swimming. Relatively little is known about the impact of retiring from athletics on bone density. It appears that former athletes continue to have a higher bone density than non-athletes; however, the rate of bone loss appears to be similar in the femoral neck. The positive impact of sports participation on bone mass can be tempered by nutritional and hormonal status. It is not known whether female athletes need additional calcium compared with the general female population. Due to the increased energy expenditure of exercise and/or the pressure to obtain an optimal training bodyweight, some female athletes may develop low energy availability or an eating disorder and subsequently amenorrhoea and a loss of bone mineral density. The three inter-related clinical disorders are referred to as the 'female athlete triad'. This article presents a review of the

    Evaluation and treatment of groin pain in athletes is challenging. The anatomy is complex, and multiple pathologies often coexist. Different pathologies may cause similar symptoms, and many systems can refer pain to the groin. Many athletes with groin pain have tried prolonged rest and various treatment regimens, and received differing opinions as to the cause of their pain. The rehabilitation specialist is often given a non-specific referral of "groin pain" or "sports hernia." The cause of pain could be as simple as the effects of an adductor strain, or as complex as athletic pubalgia or inguinal disruption. The term "sports hernia" is starting to be replaced with more specific terms that better describe the injury. Inguinal disruption is used to describe the syndromes related to the injury of the inguinal canal soft tissue environs ultimately causing the pain syndrome. The term athletic pubalgia is used to describe the disruption and/or separation of the more medial common aponeurosis from the pubis, usually with some degree of adductor tendon pathology. Both non-operative and post-operative treatment options share the goal of returning the athlete back to pain free activity. There is little research available to reference for rehabilitation guidelines and creation of a plan of care. Although each surgeon has their own specific set of post-operative guidelines, some common concepts are consistent among most surgeons. Effective rehabilitation of the high level athlete to pain free return to play requires addressing the differences in the biomechanics of the dysfunction when comparing athletic pubalgia and inguinal disruption. Proper evaluation and diagnostic skills for identifying and specifying the difference between athletic pubalgia and inguinal disruption allows for an excellent and efficient rehabilitative plan of care. Progression through the rehabilitative stages whether non-operative or post-operative allows for a focused rehabilitative program. As more

    The purpose of the study was to examine the long term effects of a selective muscle strengthening program in reducing pain and improving knee function and strength in athletes with Patellofemoral Pain Syndrome. A total of one hundred and thirty four athletes were enrolled in the study. All patients were evaluated with Isokinetic Test, Cincinnati Knee Rating System and Visual Analogue Scale. The selective muscle strengthening consisted of 8 weeks of exercises performed 3 times in the first 4 weeks and twice in the last 4 weeks. The muscle strengthening program was performed between 30-90° of knee flexion. During the first 4-weeks treatment we used closed kinetic chain exercises with 3 sets of 8 repetitions at 80% of maximum load. In the last 4-weeks we added open kinetic chain exercises at 70% of maximum load with 3 sets and 10 repetitions to improve the resistance. Analyzing data at the beginning and at the end of the treatment for Isokinetic test, Cincinnati and Visual Analogue Scale we observed a significant scores improvement. At 1 year follow-up the clinical improvements were maintained and everyone followed the recommended program because did not perform the maintenance program. At 2 years follow-up no athletes presented relapses; only four patients were excluded from program. We believe that our program of selective muscle strengthening should resolve pain and improve knee function and strength as results in obtained scores and could be critical to avoid painful relapses.

    This research tested the association between the Dark Triad and driving aggression as well as the incremental validity of the Dark Triad in predicting aggressive driving and the mediation role of the Dark Triad in the relationship between Big Five personality factors and aggressive driving. 274 undergraduate students in Study 1 and 95 amateur drivers in Study 2 completed measures of the Dark Triad (Machiavellianism, Narcissism and Psychopathy), the Big Five personality factors and the aggressive driving expression. Results showed that all the Dark Triad traits were related to aggressive driving behavior in both Study 1 and Study 2 and that the Dark Triad predicted driving aggression after the effect of the Big five personality factors was controlled, with Psychopathy being the strongest predictor of driving aggression in both Study 1 and Study 2. Machiavellianism and Psychopathy mediated the relationship between Emotional Stability, Agreeableness, Conscientiousness on one hand and aggressive driving on the other hand.

    Patients who have suffered multiple traumatic injuries, have a serious risk for death. Hypothermia, acidosis and coagulopathy are three complications in these patients, whose presence is known as lethal triad and indicates bad prognosis. To determine if the lethal triad in multiple trauma patients is associated with higher mortality and Injury Score Severity (ISS). One hundred multiple trauma patients aged 26 to 56 years (90 males), admitted to an emergency room, were studied. Body temperature, prothrombin time, partial thromboplastin time, platelet count and blood gases were determined on admission. Twenty six patients had the lethal triad and 15% died in the emergency room within the first 6 hours. No death was recorded among the 74 patients without the lethal triad. The mean ISS among patients with and without the lethal triad was 31.7 and 25.6, respectively (p < 0.05). The presence of the lethal triad among patients with multiple trauma is associated with a higher mortality and ISS.

    2016-01-01

    Context: Athletes at different skill levels perform strenuous physical activity at high altitude for a variety of reasons. Multiple team and endurance events are held at high altitude and may place athletes at increased risk for developing acute high altitude illness (AHAI). Training at high altitude has been a routine part of preparation for some of the high level athletes for a long time. There is a general belief that altitude training improves athletic performance for competitive and recreational athletes. Evidence Acquisition: A review of relevant publications between 1980 and 2015 was completed using PubMed and Google Scholar. Study Design: Clinical review. Level of Evidence: Level 3. Results: AHAI is a relatively uncommon and potentially serious condition among travelers to altitudes above 2500 m. The broad term AHAI includes several syndromes such as acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), and high altitude cerebral edema (HACE). Athletes may be at higher risk for developing AHAI due to faster ascent and more vigorous exertion compared with nonathletes. Evidence regarding the effects of altitude training on athletic performance is weak. The natural live high, train low altitude training strategy may provide the best protocol for enhancing endurance performance in elite and subelite athletes. High altitude sports are generally safe for recreational athletes, but they should be aware of their individual risks. Conclusion: Individualized and appropriate acclimatization is an essential component of injury and illness prevention. PMID:26863894

    Children and adolescents who participate in intense sports training may face physical and psychologic stresses. The pediatric health care provider can play an important role in monitoring an athlete's preparation by obtaining a proper sports history, assessing sleep hygiene, discussing nutrition and hydration guidelines, and evaluating physiologic causes of fatigue. Educating parents and athletes on the potential risks of high-intensity training, inadequate rest and sleep, and a poor diet may improve the athlete's performance and prevent symptoms of overtraining syndrome. Infectious mononucleosis must also be considered a cause of fatigue among adolescents. The signs and symptoms of overtraining and burnout are discussed in this article.

    The purpose of this study was to assess the menstrual cycle, menstrual disorders and premenstrual syndrome/premenstrual dysphoric disorder (PMS/PMDD) in girls and young women participating in competitive sports. The impact of PMS/PMDD symptoms on the quality of life was also analyzed. The prospective study encompassed 125 girls and young women with the aim to determine the presence of menstrual disorders and the prevalence of PMS/PMDD. The studied group was composed of 75 female athletes aged 16 to 22 years. The control group included 50 healthy girls and young women who did not practice competitive sports. The studied athletes and the controls prospectively evaluated their 2 consecutive menstrual cycles by using a questionnaire. The research tools were a purpose-built questionnaire, a daily log of PMS symptoms according to the American College of Obstetricians and Gynecologists' guidelines, and a daily log of PMDD symptoms based on the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnostic criteria. To determine the impact of competitive sports on the menstrual cycle, menstrual disorders, and the prevalence of PMS/PMDD in girls and young women. Intensive physical exercise delayed menarche. PMDD was diagnosed in 8% and PMS in 42.4% of all respondents. The prevalence of PMDD did not differ significantly between the groups (9.33% versus 6.00%). PMS was significantly more frequent among athletes than among controls (49.33% versus 32%, P = .045). The prevalence of PMS correlated significantly with mean age (P = .00001) and age at menarche (P = .03) in athletes. PMS was more frequent in older athletes and in girls with older age at menarche. Competitive sports, older mean age, older age at menarche, length of sporting career, and intensity of training are conducive to PMS. The prevalence of PMS increases with the duration and intensification of competitive exercises. Copyright © 2015 North American Society

    This paper addresses the question of whether one can generate networks with a given global structure (defined by selected blockmodels, i.e., cohesive, core-periphery, hierarchical, and transitivity), considering only different types of triads. Two methods are used to generate networks: (i) the newly proposed method of relocating links; and (ii) the Monte Carlo Multi Chain algorithm implemented in the ergm package in R. Most of the selected blockmodel types can be generated by considering all types of triads. The selection of only a subset of triads can improve the generated networks’ blockmodel structure. Yet, in the case of a hierarchical blockmodel without complete blocks on the diagonal, additional local structures are needed to achieve the desired global structure of generated networks. This shows that blockmodels can emerge based only on local processes that do not take attributes into account. PMID:29847563

    Do gene-gene and gene-environment interactions in folate-homocysteine (Hcy) pathway have a predisposing role for Down syndrome (DS)? The study provides evidence that in addition to advanced age, maternal genotype, micronutrient deficiency and elevated Hcy levels, individually and in combination, are risk factors for Down syndrome. Polymorphisms in certain folate-Hcy-pathway genes (especially the T allele of MTHFR C677T), elevated Hcy and poor folate levels in mothers during pregnancy have been shown to be risk factors for Down syndrome in certain Asian populations (including the eastern region of India), while the same SNPs are not a risk factor in European populations. This conflicting situation alludes to differential gene-environment (nutrition) interactions in different populations which needs to be explored. Between 2008 and 2012, 151 Down syndrome triads and 200 age-matched controls (Control mothers n = 186) were included in the study. Seven polymorphisms in six genes of folate-Hcy metabolic pathway, along with Hcy, cysteine (Cys), vitamin B12 (vit-B12) and folate levels, were analysed and compared among the case and control groups. Genotyping was performed by the PCR-RFLP technique. Levels of homocysteine and cysteine were measured by HPLC while vitamin B12 and folate were estimated by chemiluminescence. We demonstrate that polymorphisms in the folate-Hcy pathway genes in mothers collectively constitute a genotypic risk for DS which is effectively modified by interactions among genes and by the environment affecting folate, Hcy and vitamin B12 levels. The study also supports the idea that these maternal risk factors provide an adaptive advantage during pregnancy supporting live birth of the DS child. Our inability to obtain genotype and nutritional assessments of unaffected siblings of the DS children was an important limitation of the study. Also, its confinement to a specific geographic region (the eastern part) of India, and relatively small sample size

    Foli, Karen J

    2012-10-01

    This study describes the practice settings and interventions of nurses who care for members of the adoption triad (AT; birth parents, adoptive parents, child). A 28-item, descriptive, cross-sectional survey was used. Ninety-seven (97) nurses provided complete (65) or partial (32) responses. Most frequently reported practice settings were labor, delivery or postpartum unit, and pediatrics. Assessed needs varied by AT members. However, interventions for all members of the triad included emotional support and therapeutic communication. The unique placement of advanced practice nurses in various clinical settings allows for contact with members of the AT in vulnerable and crisis periods. © 2012 Wiley Periodicals, Inc.

    Over a period of three years 829 cases of greater than or equal to 16-year-old athlete exertion injuries and syndromes were collected. There were 75 women and 754 men in the series. About 90% of the athletes had been training regularly for more than two years, and 75% of them trained 6 times a week or more. Approximately 52% of the injuries occurred in track and field athletics, about 17% in ball events, 13.6% in skiing, 7.4% in orienteering, and 4.7% in power events. Other sports were associated with fewer exertion injuries. 28.7% of the conditions occurred in the knee, 17% in the ankle, foot and heel, 14.8% in the leg, 8.2% in the back and trunk, 8.1% in the thigh, 7.4% in the achilles tendon. The rest were in the shoulder, neck and upper extremities. In 92% of the patients conservative treatment and rest were used. Only 8% of the cases were treated surgically.

  20. Differentiating Dark Triad Traits Within and Across Interpersonal Circumplex Surfaces.

    2017-01-01

    Recent discussions surrounding the Dark Triad (narcissism, psychopathy, and Machiavellianism) have centered on areas of distinctiveness and overlap. Given that interpersonal dysfunction is a core feature of Dark Triad traits, the current study uses self-report data from 562 undergraduate students to examine the interpersonal characteristics associated with narcissism, psychopathy, and Machiavellianism on four interpersonal circumplex (IPC) surfaces. The distinctiveness of these characteristics was examined using a novel bootstrapping methodology for computing confidence intervals around circumplex structural summary method parameters. Results suggest that Dark Triad traits exhibit distinct structural summary method parameters with narcissism characterized by high dominance, psychopathy characterized by a blend of high dominance and low affiliation, and Machiavellianism characterized by low affiliation on the problems, values, and efficacies IPC surfaces. Additionally, there was some heterogeneity in findings for different measures of psychopathy. Gender differences in structural summary parameters were examined, finding similar parameter values despite mean-level differences in Dark Triad traits. Finally, interpersonal information was integrated across different IPC surfaces to create profiles associated with each Dark Triad trait and to provide a more in-depth portrait of associated interpersonal dynamics. © The Author(s) 2016.

    PubMed

    Forsberg, S; Lock, J

    2006-12-01

    Perfectionism is a potentially maladaptive personality trait implicated in a number of psychopathologies. As our understanding of the construct perfectionism has shifted from more unidimensionally focused conceptualizations to multidimensional ones, our ability to assess its bearing on various disorders has grown. One particular area in which perfectionism appears to play an important role is among eating disorder patients. The personalities of both those with anorexia nervosa (AN) and bulimia nervosa (BN) are thought to be intrinsically perfectionistic, which suggests a need to understand the role perfectionism plays in the development, course and outcome of these disorders. There is also an increased focus on perfectionism among athletes and its relationship to the higher prevalence of eating disorders in this group. With the institution of Title IX in the United States (which prohibited sex discrimination in higher educational settings) the participation of women in various sports has increased exponentially and with it concerns about their well-being in a milieu where a risk for menstrual irregularities, osteoporosis and eating disorders (the female athlete triad) are common. However, conflicting data suggests that athletics may be a protective factor in the development of eating disorders on the one hand, or it may be a risk factor on the other. Thus, it has become important to examine other variables, such as perfectionism, that may influence the outcome, one way or another. This review examines the current evidence about the relations between perfectionism, athletics and eating disorders.

    2011-04-01

    The Dark Triad of personality, comprising Machiavellianism, narcissism, and psychopathy, was investigated in relation to the Supernumerary Personality Inventory (SPI) traits, because both sets of variables are predominantly distinct from the Big Five model of personality. Correlational and principal factor analyses were conducted to assess the relations between the Dark Triad and SPI traits. Multivariate behavioral genetic model-fitting analyses were also conducted to determine the correlated genetic and/or environmental underpinnings of the observed phenotypic correlations. Participants were 358 monozygotic and 98 same-sex dizygotic adult twin pairs from North America. As predicted, results revealed significant correlations between the Dark Triad and most SPI traits, and these correlations were primarily attributable to common genetic and non-shared environmental factors, except in the case of Machiavellianism, where shared environmental effects emerged. Three correlated factors were extracted during joint factor analysis of the Dark Triad and SPI traits, as well as a heritable general factor of personality - results that clarified the structure of the Dark Triad construct. It is concluded that the Dark Triad represents an exploitative and antisocial construct that extends beyond the Big Five model and shares a theoretical space with the SPI traits.

    2012-11-01

    In this paper, we offer a general version of the Spanish adaptation of Athlete Burnout Questionnaire (ABQ) designed to measure the syndrome of burnout in athletes of different sports. In previous works, the Spanish version of ABQ was administered to different samples of soccer players. Its psychometric properties were appropriate and similar to the findings in original ABQ. The purpose of this study was to examine the generalization to others sports of the Spanish adaptation. We started from this adaptation, but we included three alternative statements (one for each dimension of the questionnaire), and we replaced the word "soccer" with the word "sport". An 18-item version was administered to a sample of 487 athletes aged 13 and 29 years old. Confirmatory factor analyses replicated the factor structure, but two items modification were necessary in order to obtain a good overall fit of the model. The internal consistency and test-retest reliability of the questionnaire were satisfactory.

    2015-07-01

    Sudden cardiovascular deaths in athletes are rare and only a fraction are due to aortic events. There has been concern that the hemodynamic load during exercise may lead to aortic dilation, but aortic dimensions in endurance and strength-trained athletes are only slightly larger than those in sedentary comparison subjects. The presence of a bicuspid aortic valve without significant valvular dysfunction and normal aortic dimensions should not influence eligibility to practice sport. Patients with genetic syndromes associated with aortopathy generally should be restricted from vigorous sports participation. This article reviews the diagnosis and management of diseases of the aorta in athletes. Copyright © 2015 Elsevier Inc. All rights reserved.

    2016-08-01

    Hip or groin pain in athletes is common and clinical presentation is often nonspecific. Imaging is a very important diagnostic step in the work-up of athletes with hip pain. This review article provides an overview on hip biomechanics and discusses strategies for hip imaging modalities such as radiography, ultrasonography, computed tomography, and magnetic resonance (MR) imaging (MR arthrography and traction MR arthrography). The authors explain current concepts of femoroacetabular impingement and the problem of high prevalence of cam- and pincer-type morphology in asymptomatic persons. With the main focus on MR imaging, the authors present abnormalities of the hip joint and the surrounding soft tissues that can occur in athletes: intraarticular and extraarticular hip impingement syndromes, labral and cartilage disease, microinstability of the hip, myotendinous injuries, and athletic pubalgia.

    The ingestion of calcium, along with alkali, results in a well-described triad of hypercalcemia, metabolic alkalosis, and renal insufficiency. Over time, the epidemiology and root cause of the syndrome have shifted, such that the disorder, originally called the milk-alkali syndrome, is now better described as the calcium-alkali syndrome. The calcium-alkali syndrome is an important cause of morbidity that may be on the rise, an unintended consequence of shifts in calcium and vitamin D intake in segments of the population. We review the pathophysiology of the calcium-alkali syndrome. PMID:24288027

    2012-01-01

    Context: Fatigue and underperformance are common in athletes. Understanding overtraining syndrome (OTS) is helpful in the evaluation, management, and education of athletes. Evidence Acquisition: Relevant articles in English were searched with OVID (1948-2011) and PubMed using the following keywords: overtraining syndrome, overtraining, overreaching, unexplained underperformance, staleness, pathophysiology, management, treatment, evaluation. Bibliographies were reviewed for additional resources. Results: OTS appears to be a maladapted response to excessive exercise without adequate rest, resulting in perturbations of multiple body systems (neurologic, endocrinologic, immunologic) coupled with mood changes. Many hypotheses of OTS pathogenesis are reviewed, and a clinical approach to athletes with possible OTS (including history, testing, and prevention) is presented. Conclusions: OTS remains a clinical diagnosis with arbitrary definitions per the European College of Sports Science’s position statement. History and, in most situations, limited serologies are helpful. However, much remains to be learned given that most past research has been on athletes with overreaching rather than OTS.

    Many athletes struggle with groin pain for years without ever receiving a clear diagnosis or being offered an effective treatment plan. Confusion among treatment providers can also frequently lead to suboptimal surgeries for presumed hernias or nerve entrapment syndromes. Imaging, and in particular magnetic resonance (MR) imaging, should play a primary role in the workup, diagnosis, and treatment of athletic pubalgia. This review outlines standard of care, cutting-edge MR imaging techniques for athletic pubalgia, and reviews the spectrum of imaging findings that are encountered in this patient group.

    2015-01-01

    We experienced two cases involving the simultaneous presence of cholelithiasis, hiatal hernia, and umbilical hernia. Both patients were female and overweight (body mass index of 25.0-29.9 kg/m(2)) and had a history of pregnancy and surgical treatment of cholelithiasis. Additionally, both patients had two of the three conditions of Saint's triad. Based on analysis of the pathogenesis of these two cases, we consider that these four diseases (Saint's triad and umbilical hernia) are associated with one another. Obesity is a common risk factor for both umbilical hernia and Saint's triad. Female sex, older age, and a history of pregnancy are common risk factors for umbilical hernia and two of the three conditions of Saint's triad. Thus, umbilical hernia may readily develop with Saint's triad. Knowledge of this coincidence is important in the clinical setting. The concomitant occurrence of Saint's triad and umbilical hernia may be another clinical "tetralogy."

    Two daughters of phenotypically normal parents are described with severe proportional dwarfism with microcephaly, peculiar craniofacial anomalies, microtia, absent patellae, joint hyperextensibility, and other anomalies. Intrafamilial variability is minimal. This combination of anomalies has many similarities to the six cases previously described with the Ear, Patellae, Short stature syndrome (Meier-Gorlin syndrome), which is distinguished by the triad of microtia, absent patellae and growth retardation. Autosomal recessive inheritance is strongly suggested by the presence of two pairs of affected siblings and the equal sex ratio.

  16. Conformational Entropy of Intrinsically Disordered Proteins from Amino Acid Triads

    PubMed Central

    Baruah, Anupaul; Rani, Pooja; Biswas, Parbati

    2015-01-01

    This work quantitatively characterizes intrinsic disorder in proteins in terms of sequence composition and backbone conformational entropy. Analysis of the normalized relative composition of the amino acid triads highlights a distinct boundary between globular and disordered proteins. The conformational entropy is calculated from the dihedral angles of the middle amino acid in the amino acid triad for the conformational ensemble of the globular, partially and completely disordered proteins relative to the non-redundant database. Both Monte Carlo (MC) and Molecular Dynamics (MD) simulations are used to characterize the conformational ensemble of the representative proteins of each group. The results show that the globular proteins span approximately half of the allowed conformational states in the Ramachandran space, while the amino acid triads in disordered proteins sample the entire range of the allowed dihedral angle space following Flory’s isolated-pair hypothesis. Therefore, only the sequence information in terms of the relative amino acid triad composition may be sufficient to predict protein disorder and the backbone conformational entropy, even in the absence of well-defined structure. The predicted entropies are found to agree with those calculated using mutual information expansion and the histogram method. PMID:26138206

  18. Specificity of the histopathological triad for the diagnosis of toxoplasmic lymphadenitis: polymerase chain reaction study.

    PubMed

    2001-08-01

    Toxoplasmosis is a common cause of lymphadenopathy, but toxoplasmic cysts are not usually found in histological sections used for establishing diagnosis, except on extremely rare occasions. The histopathological triad of florid reactive follicular hyperplasia, clusters of epithelioid histiocytes, and focal sinusoidal distention by monocytoid B cells has been considered to be diagnostic of toxoplasmic lymphadenitis, but the validity of the histopathological triad is based indirectly on serological correlation only. The demonstration of Toxoplasma gondii DNA in lymph nodes displaying the histopathological triad will indicate the validity of the histopathological triad as the criterion for the histopathological diagnosis of toxoplasmic lymphadenitis. We used frozen tissues of 12 lymph nodes with the histopathological triad and tissues of 27 lymph nodes from patients with various other conditions (including 13 cases of follicular lymphoid hyperplasia, FLH; three cases of dermatopathic lymphadenopathy, DPL; two cases of plasmacytosis; two cases of Castleman's disease; two cases of metastatic adenocarcinoma; and five cases of lymphoma) to detect T. gondii DNA by polymerase chain reaction. Ten out of 12 lymph nodes with the triad and six out of 27 lymph nodes without the triad were positive for T. gondii DNA. Thus, the sensitivity of the triad was 62.5% (10/16) and the specificity was 91.3% (21/23). The predictive value of positive tests was 83.3% (10/12) and the predictive value of negative tests was 77.7% (21/27). The six cases positive for T. gondii DNA without the triad were four cases of FLH, one case of DPL, and one case of plasmacytosis. None of the neoplastic diseases was positive. The false positive and negative cases could be due to sampling problems or past T. gondii infection. The results confirm that the histopathological triad is highly specific for the diagnosis of toxoplasmic lymphadenitis and can be used confidently.

    2003-07-01

    Currarino triad, which comprises anorectal stenosis, anterior sacral defect, and a presacral mass, is an uncommon cause of constipation in children and adults. The presacral mass in this triad is most often caused by an anterior sacral meningocele, a teratoma, or an enterogenous cyst, but rarely may be caused by dual pathology. A neonate with Currarino triad and dual pathology in the presacral mass is described in this report. A male Chinese neonate, who presented with abdominal distention and constipation on the second day of life, was found to have features of Currarino triad. Colostomy was done in the neonatal period, and the presacral mass was excised by posterior sagittal perineal approach at the age of six months. The excised presacral mass consisted of an anterior meningocele and a teratoma. The patient continued to have constipation during follow-up and required anorectoplasty to correct residual anorectal stenosis. At the time of this report the patient was three years old and growing normally with normal anorectal function. Of a total of about 200 cases of complete Currarino triad found in the literature, in only 22 patients did the presacral mass contain both meningocele and teratoma. The features of these 22 patients and the current views on the surgical management of Currarino triad are discussed.

    Work on the Dark Triad traits has benefited from the use of a life history framework but it has been limited to primarily Western samples and indirect assessments of life history strategies. Here, we examine how the Dark Triad traits (i.e., psychopathy, Machiavellianism, and narcissism) relate to two measures of individual differences in life history strategies. In Study 1 ( N = 937), we replicated prior observed links between life history strategies, as measured by the Mini- K , and the Dark Triad traits using samples recruited from three countries. In Study 2 ( N = 1032), we measured life history strategies using the Consideration of Future Consequences Scale and correlated it with the Dark Triad traits in samples recruited from three additional countries. While there was some variability across participants' sex and country, the results were generally consistent in that psychopathy and (to a lesser extent) Machiavellianism were related to faster life history strategies and narcissism was related to slower life history strategies. These results add cross-cultural data and the use of two measures of life history speed to understand the Dark Triad traits from a life history perspective.

We are reporting a case with two episodes of MFS within two years. Initially he presented with partial ophthalmoplegia, ataxia. Second episode was characterized by full-blown presentation characterized by ataxia, areflexia and ophthalmoplegia. CSF analysis was typical during both episodes. Nerve conduction velocity study was fairly within normal limits. MRI of brain was within normal limits. He responded to symptomatic measures initially, then to steroids in the second episode. We are reporting the case due to its rarity.

    Patellofemoral pain syndrome (PFPS) is one of the most common causes of knee pain and is present in females disproportionately more relative to males. PFPS causes tend to be multifactorial in nature and are described in this review. From a review of the current literature, it is clear that there needs to be further research on PFPS in order to better understand the complex etiology of this disorder in both males and females. It is known that females with patellofemoral pain syndrome demonstrate a decrease in abduction, external rotation and extension strength of the affected side compared with healthy patients. Conservative management, including optimizing muscle balance between the vastus medialis and lateralis around the patella along with formal therapy should be the first line of treatment in patients presenting with PFPS. Surgery should be reserved for patients in which all conservative management options have failed. This review aims to guide physicians in accurate clinicaldecision making regarding conservative and surgical treatment options when specifically faced with PFPS in a female athlete. Furthermore, we will discuss the anatomic variants, incidence and prevalence, etiology, diagnosis and treatment of PFPS.

    simplified diagnostic swine influenza (H1N1) triad was developed for the rapid clinical diagnosis of probable H1N1 pneumonia, which also differentiated it from its mimics as well as from bacterial pneumonia, eg, Legionnaires' disease. During the "herald wave" of the H1N1 pandemic, we noticed an unexplained increase in Legionnaires' disease CAPs. Because clinical resources were stressed to the maximum during the pandemic, it was critically important to rapidly identify patients rapidly with Legionnaire's disease who did not require influenza precautions or oseltamivir, but who did require anti-Legionella antimicrobial therapy. Based on the Winthrop-University Hospital Infectious Disease Division's diagnostic weighted point score system for Legionnaires' disease (modified), key indicators were identified and became the basis for the diagnostic Legionnaires' disease triad. The diagnostic Legionnaires' disease triad was used to make a clinical diagnosis of Legionnaires' disease until the results of Legionella diagnostic tests were reported. The diagnostic Legionnaires' disease triad diagnosed Legionnaires' disease in hospitalized adults with CAPs with extrapulmonary findings (atypical CAP) and relative bradycardia, accompanied by any three (ie, a triad) of the following: otherwise unexplained relative lymphopenia, early/mildly elevated serum transaminases (SGOT/SGPT), highly increased ferritin levels (> or =2 x n), or hypophosphatemia. The diagnostic Legionnaires' disease triad provides clinicians with a rapid way to clinically diagnose Legionnaires' disease, pending Legionella test results. The accuracy of the diagnostic Legionnaires' disease triad was confirmed in our 9 cases of Legionnaires' disease by subsequent Legionella diagnostic testing. The diagnostic Legionnaires' disease triad is particularly useful in situations where a rapid clinical syndromic diagnosis is needed, ie, during an H1N1 pandemic. Copyright 2010 Elsevier Inc.

    Carpal tunnel syndrome is a neuropathy resulting from compression of the median nerve as it passes through a narrow tunnel in the wrist on its way to the hand. The lack of precise objective and clinical tests, along with symptoms that are synonymous with other syndromes in the upper extremity, cause carpal tunnel syndrome to appear to be a rare entity in athletics. However, it should not be ruled out as a possible etiology of upper extremity paralysis in the athlete. More typically, carpal tunnel syndrome is the most common peripheral entrapment neuropathy encountered in industry. Treatment may include rest and/or splinting of the involved wrist, ice application, galvanic stimulation, or iontophoresis to reduce inflammation, and then transition to heat modalities and therapeutic exercises for developing flexibility, strength, and endurance. In addition, an ergonomic assessment should be conducted, resulting in modifications to accommodate the carpal tunnel syndrome patient. ImagesFig 3.Fig 4.Fig 5.Fig 6.Fig 7. PMID:16558255

    The clinical syndrome of athletic pubalgia has prematurely ended many promising athletic careers, has made many active, fitness conscious adults more sedentary, and has served as a diagnostic and therapeutic conundrum for innumerable trainers and physicians worldwide for decades. This diagnosis actually arises from one or more lesions within a spectrum of musculoskeletal and visceral injuries. In recent years, MRI has helped define many of these syndromes, and has proven to be both sensitive and specific for numerous potential causes of athletic pubalgia. This text will provide a comprehensive, up to date review of expected and sometimes unexpected MRI findings in the setting of athletic pubalgia, and will delineate an imaging algorithm and MRI protocol to help guide radiologists and other clinicians dealing with refractory, activity related groin pain in an otherwise young, healthy patient. There is still more to be learned about prevention and treatment plans for athletic pubalgia lesions, but accurate diagnosis should be much less nebulous and difficult with the use of MRI as a primary imaging modality.

    [Purpose] The purpose of this study is to examine the effect of aroma stimulation during isotonic exercise on the rating of perceived exertion (RPE) and the blood fatigue factors of athletes who have patellofemoral pain syndrome (PFPS). [Subjects and Methods] The research subjects were seven athletes in their twenties who suffer from PFPS. They were divided into a control group and an aroma stimulation group and performed isotonic exercises repeatedly. After exercising, the RPE and blood fatigue factors, including creatine phosphokinase (CPK), lactate dehydrogenase (LDH), and ammonia, were measured through blood sampling. [Results] The aroma stimulus group showed significantly lower RPE than the control group immediately after exercising, which included leg presses, leg curls, bicep curls, and leg extensions. Among the blood fatigue factors, the change in LDH indicated the effect of aroma stimulation. [Conclusion] We confirmed that aroma stimulation during isotonic exercise has the positive effect of reducing the RPE and blood fatigue factors, such as blood LDH, of the athletes with PFPS.

    Enlargement of the left atrium is perceived as a part of athlete's heart syndrome, despite the lack of evidence. So far, left atrial size has not been assessed in the context of exercise capacity. The hypothesis of the present study was that LA enlargement in athletes was physiological and fitness-related condition. In addition, we tried to assess the feasibility and normal values of left atrial strain parameters and their relationship with other signs of athlete's heart. The study group consisted of 114 international-level rowers (17.5 ± 1.5 years old; 46.5% women). All participants underwent a cardio-pulmonary exercise test and resting transthoracic echocardiography. Beside standard echocardiographic measurements, two dimensional speckle tracking echocardiography was used to assess average peak atrial longitudinal strain, peak atrial contraction strain and early left atrial diastolic longitudinal strain. Mild, moderate and severe left atrial enlargement was present in 27.2°%, 11.4% and 4.4% athletes, respectively. There were no significant differences between subgroups with different range of left atrial enlargement in any of echocardiographic parameters of the left ventricle diastolic function, filling pressure or hypertrophy. A significant correlation was found between the left atrial volume index and maximal aerobic capacity (R > 0.3; p < 0.001). Left atrial strain parameters were independent of atrial size, left ventricle hypertrophy and left ventricle filling pressure. Decreased peak atrial longitudinal strain was observed in 4 individuals (3.5%). We concluded that LA enlargement was common in healthy, young athletes participating in endurance sport disciplines with a high level of static exertion and was strictly correlated with exercise capacity, therefore, could be perceived as another sign of athlete's heart.

  11. Popliteal Artery Entrapment or Chronic Exertional Compartment Syndrome?

    2017-01-01

    Diagnosis of lower limb pain in an athlete can be a challenging task due to the variety of potential etiologies and ambiguity of presenting symptoms. Five of the most commonly encountered causes of limb pain in athletes are chronic exertional compartment syndrome (CECS), medial tibial stress syndrome (MTSS), tibial stress fractures, soleal sling syndrome, and popliteal artery entrapment syndrome (PAES). Of these, the least frequent but potentially most serious of the pathologies is PAES. With an incidence of less than 1% seen in living subject studies, the condition is rare. However, a missed diagnosis will likely lead to progression of the disease and potential for unnecessary invasive procedures (McAree et al. 2008). In this paper, we present a young athlete misdiagnosed and treated for chronic exertional compartment syndrome. In both descriptive and a quick-reference table format, we review current literature and discuss how best to distinguish functional PAES from other causes of activity-related leg pain. PMID:28890727

    2011-01-01

    Multi-disciplinary and multi-site biomedical research programs frequently require infrastructures capable of enabling the collection, management, analysis, and dissemination of heterogeneous, multi-dimensional, and distributed data and knowledge collections spanning organizational boundaries. We report on the design and initial deployment of an extensible biomedical informatics platform that is intended to address such requirements. A common approach to distributed data, information, and knowledge management needs in the healthcare and life science settings is the deployment and use of a service-oriented architecture (SOA). Such SOA technologies provide for strongly-typed, semantically annotated, and stateful data and analytical services that can be combined into data and knowledge integration and analysis "pipelines." Using this overall design pattern, we have implemented and evaluated an extensible SOA platform for clinical and translational science applications known as the Translational Research Informatics and Data-management grid (TRIAD). TRIAD is a derivative and extension of the caGrid middleware and has an emphasis on supporting agile "working interoperability" between data, information, and knowledge resources. Based upon initial verification and validation studies conducted in the context of a collection of driving clinical and translational research problems, we have been able to demonstrate that TRIAD achieves agile "working interoperability" between distributed data and knowledge sources. Informed by our initial verification and validation studies, we believe TRIAD provides an example instance of a lightweight and readily adoptable approach to the use of SOA technologies in the clinical and translational research setting. Furthermore, our initial use cases illustrate the importance and efficacy of enabling "working interoperability" in heterogeneous biomedical environments.

    Cyclic sedimentation and lateral facies changes make coal bed correlations inconclusive and difficult. This uncertainty can be further complicated if a coal basin has been structurally deformed. Coal macerals can be studied to indicate the nature and degree of coalification. Their use in coal bed correlation, however, is limited. Most of the trace elements and their ratios that have been studied show significant within-bed lateral and stratigraphic variations, and thus are not effective in correlating coal beds regionally. Geochemically coherent groups of elements, such as rare earth elements (REE) and platinum group elements (PGE), appear to be highly differentiated in coal-forming environments. Geochemical coherent elemental triads appear to be useful for coal bed identification or fingerprinting. The best triad which was demonstrated to be effective in coal bed characterization in western Kentucky, is that of Al, La and Sc. These three elements are highly correlated with one another and they can be determined accurately and simultaneously with instrumental neutron activation analysis (INAA). The elemental triad Al-La-Sc is used to identify and fingerprint three key coal beds in western Kentucky: the Springfield (western Kentucky No. 9), the Davis (western Kentucky No. 6), and the Mining City and Dawson Springs are both considered to be the No. 4 coal bed in western Kentucky). Four distinct groupings can be recognized by use of the Al-La-Sc triad. The Dawson Springs coals have the highest Al/(La + Sc) ratios, followed by the Springfield, the Davis and the Mining City. The Mining City coal bed generally has the highest La/Sc ratio. However, the Dawson Springs is not correlated with the Mining City using the triad analysis, even though they have reportedly similar stratigraphic positions in the western Kentucky coal basin. The Al-La-Sc triad appears to be effective in discriminating between the Springfield and the Davis coal beds throughout the entire Illinois

    Pelvic stress fractures, osteitis pubis, and snapping hip syndrome account for a portion of the overuse injuries that can occur in the running athlete. PUBMED SEARCHES WERE PERFORMED FOR EACH ENTITY USING THE FOLLOWING KEYWORDS: snapping hip syndrome, coxa sultans, pelvic stress fracture, and osteitis pubis from 2008 to 2013. Topic reviews, case reports, case series, and randomized trials were included for review. Clinical review. Level 4. Collectively, 188 articles were identified. Of these, 58 were included in this review. Based on the available evidence, the majority of these overuse injuries can be managed non-operatively. Primary treatment should include removal from offending activity, normalizing regional muscle strength/length imbalances and nutritional deficiencies, and mitigating training errors through proper education of the athlete and training staff.

    To present the case of 2 adolescent high school student-athletes who developed postconcussion syndrome with protracted and limiting visual complaints that markedly affected academic, social, and athletic activity for a year after the onset of symptoms. Both had significant improvement soon after a unique intervention was administered. A 14-year-old female soccer and softball player sustained 2 concussions in the same week. She had persistent symptoms for a year that affected her grades and precluded athletic participation. A 15-year-old male football player sustained a concussion during an altercation with 2 other male adolescents. He continued to have symptoms 1 year later, with a marked decrease in academic performance and restriction from athletics. Both adolescents reported blurry vision, photophobia, and associated headache as significant components of the postconcussion syndrome. Concussion, postconcussion syndrome, skull fracture, subdural hematoma, epidural hematoma, second-impact syndrome, and visually sensitive migraine. Both patients were advised to obtain computer gaming glasses to use throughout the day. The female patient was diligent in her use of the glasses, with marked lessening of symptoms. The male patient was less accepting of the glasses but did report lessening of symptoms when using the glasses. We hypothesized that postconcussion syndrome with marked visual complaints would respond to and improve with decreased stimulation of the visual system. This was attempted with the addition of computer gaming glasses. Both adolescent athletes responded well to the filtering of visual stimuli by off-the-shelf computer gaming glasses. Postconcussion syndrome is a persistent condition with a myriad of symptoms. Two young athletes developed postconcussion syndrome with prominent visual symptoms that lasted a year. The addition of computer gaming glasses markedly lessened symptoms in both patients.

  17. Aortic root dilatation in athletic population.

    PubMed

    2012-01-01

    Remodeling of the aortic root may be expected to occur in athletes as a consequence of hemodynamic overload associated with exercise training; however, there are few data reporting its presence or extent. This review reports the current knowledge regarding the prevalence, upper limits, and clinical significance of aortic remodeling induced by athletic training. Several determinants impact aortic dimension in healthy, nonathletic individuals, including height, body size, age, sex, and blood pressure. Of these factors, anthropometric variables have the greatest impact. In athletes, the effect of exercise training appears to have only a modest additional influence on aortic dimension, although previous studies have produced some conflicting results. Specifically, data derived from the largest available athletic cohort suggest that the most hemodynamically intense endurance disciplines (eg, cycling and swimming) are associated with a significant but mild increase in aortic dimensions. Power disciplines, instead, (eg, weight lifting, throwing events) have only trivial, if any, impact. In contrast, selected data from a different athlete population suggest a more significant dimensional aortic remodeling in strength-trained individuals. In our experience, the 99th percentile value of aortic root diameter corresponds to 40 mm in males and 34 mm in females, which can reasonably be considered the upper limits of physiologic aortic root remodeling. However, a small proportion of apparently healthy male athletes (approximately 1%) show aortic enlargement above the upper limits, in the absence of systemic disease (ie, Marfan syndrome). Athletes presenting with aortic enlargement may demonstrate a further dimensional increase in midlife leading to clinically relevant aortic dilatation. Occasionally, dilation may be severe enough to warrant consideration for surgical treatment. Therefore, serial clinical and echocardiographic evaluations are recommended in athletes when aortic

    The primary aim of this article is to examine the role of triad affiliation in mediating the relationship between child maltreatment (neglect, punishment, emotional abuse, and sexual abuse) and delinquency among active young gang members in Hong Kong. A sample of 177 gang members aged 12 to 24 was recruited to complete a questionnaire with the assistance of a youth outreach social work team. Neglect was identified as the most common form of maltreatment, followed by emotional abuse, punishment, and sexual abuse. Mediation analyses confirmed that triad affiliation acts as a mediating variable in the child maltreatment-delinquency relationship, except in cases of sexual abuse. Only the relationship between punishment and delinquency was found to be fully mediated by triad affiliation; partial mediation effects were found for neglect and emotional abuse. Recommendations for child protection and youth workers are provided.

    Susac Syndrome is a rare entity, characterized by a triad of subacute encephalopathy, retinal artery occlusion and sensorineural hearing loss. It is more common in women and the age of onset fluctuates between 9-58 years of age. The pathogenesis is presented as microangiopathic changes at the cerebral, retinal and cochlear levels associated with an autoimmune mechanism. We present the case of a 31-year-old woman who started with a diffuse headache, puerile behavior, bradylalia and somnolence. As the disease progressed, she had auditory deficit and arterial obstruction of the right temporal retinal branch in retinal fluorescein angiography. Brain magnetic resonance showed rounded hyperintense lesions in the corpus callosum, periventricular region and cerebellum. This is the first reported case of Susac Syndrome in Peru, presented with the classic triad, which is an infrequent presentation. However, cases that show incomplete forms should be evaluated in a timely manner to initiate timely treatment and avoid irreversible consequences.

    The aim of this work focuses on the relationship among the Dark Triad (psychopathy, narcissism, and Machiavellianism), perceptions of organizational politics, political skills, and counterproductive work behavior. This study empirically tests the mediating role of perceptions of organizational politics in the relationship between the Dark Triad and counterproductive work behavior. Furthermore, the study investigates the moderating role of political skills in strengthening the link between the Dark Triad and the perceptions of organizational politics. A sample of 149 participants was randomly selected. To analyze the data of the present work, we employed a structural equation model using partial least square and PROCESS. From empirical findings, we imply an inference that perception of organizational politics partially mediates the Dark Triad's influence on the counterproductive work behavior. Moreover, the results identify the moderating role of political skills in strengthening the link between the Dark Triad and the perceptions of organizational politics. Empirical findings suggest important policy implications for the hospitality industry. PMID:29167654

    Athletic pubalgia is a frequently encountered syndrome for clinicians who treat active patients participating in a wide variety of athletic endeavors worldwide. Pathologies associated with this clinical scenario span anatomically from the pubic symphysis to the hip and include a myriad of poorly understood and incompletely described musculoskeletal entities, many of which are centered about the pubic symphysis and its tendinous attachments. In this article, we discuss the relevant anatomy and pathophysiology for the most frequently encountered of these disorders, using magnetic resonance (MR) images as a guide. We describe an MR imaging protocol tailored to clinical athletic pubalgia. We then review reproducible MRI patterns of pathology about the pubic symphysis, the rectus abdominis/adductor aponeurosis and the inguinal ring, as well as a group of clinically confounding entities remote from the symphysis but visible by MRI.

    The Dark Triad is a collection of socially aversive personality traits, namely subclinical psychopathy, Machiavellianism, and subclinical narcissism. These deviant traits, however, contribute to the success of individuals with dark personality traits. Therefore, Dark Triad traits can be conceived as pseudopathologies. Schizotypal traits have also been studies from the perspective of behavioral adaptations. In this study, we investigated whether schizotypal traits were associated with the Dark Triad traits and how schizotypal symptoms can be considered as parts of dark interpersonal strategies that contribute to the individual success of people with dark personality traits. A sample of 277 university students (198 females and 79 males; M age  = 20.64; SD age  = 2.15) were recruited to fill out the Short Dark Triad and the Schizotypal Personality Questionnaire-Brief Revised. Statistical analyses revealed that Machiavellianism was positively associated with restricted emotional and social life. Narcissism was negatively associated with interpersonal problems. Psychopathy was positively associated with distorted perceptions/cognitions and disorganization. Results of the study are discussed within a behavioral ecology framework. This perspective emphasizes the adaptive values connected to schizotypal personality traits. We further discuss how these adaptive traits fit into strategies of individuals with Dark Triad traits, and how these schizotypal traits might restrict or further promote their individual success.

    2009-01-01

    Posterior ankle and heel pain is common among athletes. The most common injury in this region is that of the Achilles tendon. However, besides the Achilles tendon, pain can originate from a retrocalcaneal bursitis, posterior impingement syndrome, os trigonum syndrome, or flexor hallucis longus tenosynovitis. These pathologies often caused by overuse, but can also occur after trauma. With careful examination, and the help of MRI imaging, the distinction can be made among these pathologies and the more common Achilles tendon problems. Like most overuse injuries, the majority of cases of retrocalcaneal bursitis, posterior impingement, flexor hallucis longus tenosynovitis respond to conservative treatment. However, when this fails, open or arthroscopic surgery can be proposed. Arthroscopy is less aggressive than open surgery, with the added advantage of less patient morbidity, less post-operative pain, and early functional rehabilitation. It is becoming the surgery of choice, especially among athletes.

    Wernicke-Korsakoff syndrome in patients with cancer is understudied. Much of what is known-that significant under-recognition and delays in treatment exist-comes from studies of alcohol misuse disorders or non-alcohol-related Wernicke-Korsakoff syndrome in patients. We investigated the frequency and associated features of cancer-related Wernicke-Korsakoff syndrome in the published literature. We included 90 articles reporting on 129 patients. Only 38 (30%) of 128 patients with data available exhibited the entire triad of classic features of Wernicke-Korsakoff syndrome: confusion, ataxia, and ophthalmoplegia or nystagmus. Diagnosis during life was missed altogether in 22 (17%) of 128 patients. The operational diagnostic criteria (at least two of the following: nutritional deficiency, ocular signs, cerebellar signs, and either altered mental status or mild memory impairment), which are considered more reliable than the classical triad, were used in only nine (7%) cases, yet 120 (94%) met the operational criteria for diagnosis at the time of presentation when applied retroactively. Complete recovery was reported in only 47 (36%) cases. Given that oncologists or haematologists accounted for only 17 (19%) first authors among the articles included, it is important that oncologists are aware of the risk factors for cancer-related Wernicke-Korsakoff syndrome, and that they are vigilant about diagnosing and treating the disease especially in the absence of alcohol misuse disorders.

    2017-04-01

    The Dark Triad traits have been repeatedly labeled as facilitating an exploitive mating strategy. However, various researchers have repeatedly conflated short-term mating or casual sex with an exploitive mating strategy. In this study using Mechanical Turk participants (N = 252; 142 men, 110 women), we provided a better test of just how sexually exploitive those high on the Dark Triad traits might be by examining how the traits related to rape-enabling attitudes. We examined how each trait may facilitate rape, whether these associations were robust to partialing the variance associated with the Big Five traits and similar in men and women, and showed that one reason why men may be more likely to rape than women is they are characterized by the Dark Triad traits more than women are. In so doing, we test the confluence model of rape that asserts that personality traits similar to the Dark Triad traits act as one pathway to rape.

  15. Shin pain in athletes - assessment and management.

    PubMed

    Blackman, Paul

    2010-01-01

    Shin pain is a common complaint among running athletes and can be caused by bony, muscular, vascular or neural pathology. This article discusses the likely causes, assessment and management of shin pain in athletes presenting in the general practice setting. Accurate diagnosis is important as treatment differs depending on the cause. The characteristics of the pain and examination findings after exercise give strong clues to the diagnosis; further investigation may be unnecessary. Bony stress reactions and fractures are the most common cause of shin pain; patients describe a 'jarring' sensation along the bone margin with heel strike. Other causes include recurrent exertional compartment syndrome (RECS), tenosynovitis, neurological entrapment and rarely, vascular entrapment. Symptoms of vascular entrapment may be similar to RECS and this may cause diagnostic confusion. Increased bone stress in athletes is largely due to inappropriate training program design and can usually be alleviated by reducing impact loading until pain resolves.

    Objective: Social support has been identified repeatedly in the literature as being beneficial to individuals suffering from injury or illness. Because of the frequent interaction between athletic trainers and student athletes, the athletic trainer is in a unique position to provide a variety of social support to the athlete. The purpose of the study was (1) to identify the degree to which athletes actually receive each of eight types of social support; (2) to identify the types of social support athletes need or expect to receive from staff and student athletic trainers; and (3) to compare the athletes' satisfaction with the quality of the support received from athletic training staff and students. Design and Setting: A questionnaire was used to collect data for this study. It was administered at a Division I university. Subjects: Eighty-five student-athletes at a Division I university. Measurements: The survey consisted of 24 questions that used a five-point Likert rating scale. Results: There was no significant difference in the amount of social support received by athletes from staff and student athletic trainers, in athletes' expectations of staff and student athletic trainers with regard to provision of social support, or in the athletes' level of satisfaction with staff and student athletic trainers' provision of social support. Conclusions: Examined collectively, the findings indicate that athletes do not differentiate between staff and student athletic trainers with regard to the provision of social support. However, finding that athletes do not differentiate between staff and student athletic trainers in this area is significant in itself and has implications for athletic training education programs.

    Phosphopantetheinyl transferases (PPTases), which play an essential role in both primary and secondary metabolism, are magnesium binding enzymes. In this study, we characterized the magnesium binding residues of all known group II PPTases by biochemical and evolutionary analysis. Our results suggested that group II PPTases could be classified into two subgroups, two-magnesium-binding-residue-PPTases containing the triad Asp-Xxx-Glu and three-magnesium-binding-residue-PPTases containing the triad Asp-Glu-Glu. Mutations of two three-magnesium-binding-residue-PPTases and one two-magnesium-binding-residue-PPTase indicate that the first and the third residues in the triads are essential to activities; the second residues in the triads are non-essential. Although variations of the second residues in the triad Asp-Xxx-Glu exist throughout the whole phylogenetic tree, the second residues are conserved in animals, plants, algae, and most prokaryotes, respectively. Evolutionary analysis suggests that: the animal group II PPTases may originate from one common ancestor; the plant two-magnesium-binding-residue-PPTases may originate from one common ancestor; the plant three-magnesium-binding-residue-PPTases may derive from horizontal gene transfer from prokaryotes.

    In past years, research and corporate scandals have evidenced the destructive effects of the dark triad at work, consisting of narcissism (extreme self-centeredness), psychopathy (lack of empathy and remorse) and Machiavellianism (a sense of duplicity and manipulativeness). The dark triad dimensions have typically been conceptualized as stable personality traits, ignoring the accumulating evidence that momentary personality expressions – personality states – may change due to the characteristics of the situation. The present research protocol describes a qualitative study that aims to identify triggers of dark triad states at work by following a grounded theory approach using semi-structured interviews. By building a comprehensive categorization of dark triad triggers at work scholars may study these triggers in a parsimonious and structured way and organizations may derive more effective interventions to buffer or prevent the detrimental effects of dark personality at work.

    2009-12-01

    A classic triad of symptoms (bladder pain, urinary frequency, and urgency) has served to define bladder pain syndrome/painful bladder syndrome/interstitial cystitis (BPS/PBS/IC) syndrome. BPS/PBS/IC is a distinct condition and it is likely that the urgency experienced by these patients differs from that experienced by those with overactive bladder syndrome. It is unclear how best to define urgency in the BPS/PBS/IC setting. Differences in the other primary symptoms associated with these conditions probably influence how urgency is perceived. Advances in research into the pathophysiology of urgency and underlying disease processes will help to optimize both the diagnosis and treatment of BPS/PBS/IC.

    Floating-Harbor syndrome is a rare syndrome of unknown etiology, which was first described in 1973. A triad of main features characterizes Floating-Harbor syndrome: short stature, characteristic face, and an expressive speech delay. We present a patient in whom the hearing thresholds improved insufficiently after placement of grommets. High-resolution CT scan of the temporal bone showed a prominent soft-tissue thickening suspected of causing fixation of the malleus, and fusion of the malleus head with the body of the incus. To our knowledge this is the first reported abnormal middle ear anatomy in a patient with Floating-Harbor syndrome. A conservative treatment with hearing aids was preferred as an initial treatment in favor of a surgical exploration.

  5. Participation in ball sports may represent a prehabilitation strategy to prevent future stress fractures and promote bone health in young athletes.

    Sports participation has many benefits for the young athlete, including improved bone health. However, a subset of athletes may attain suboptimal bone health and be at increased risk for stress fractures. This risk is greater for female than for male athletes. In healthy children, high-impact physical activity has been shown to improve bone health during growth and development. We offer our perspective on the importance of promoting high-impact, multidirectional loading activities, including ball sports, as a method of enhancing bone quality and fracture prevention based on collective research. Ball sports have been associated with greater bone mineral density and enhanced bone geometric properties compared with participation in repetitive, low-impact sports such as distance running or nonimpact sports such as swimming. Runners and infantry who participated in ball sports during childhood were at decreased risk of future stress fractures. Gender-specific differences, including the coexistence of female athlete triad, may negate the benefits of previous ball sports on fracture prevention. Ball sports involve multidirectional loading with high ground reaction forces that may result in stiffer and more fracture-resistant bones. Encouraging young athletes to participate in ball sports may optimize bone health in the setting of adequate nutrition and in female athletes, eumenorrhea. Future research to determine timing, frequency, and type of loading activity could result in a primary prevention program for stress fracture injuries and improved life-long bone health.

    The paramedian diencephalic syndrome is characterized by a clinical triad: hypersomnolent apathy, amnesic syndrome, and impaired vertical gaze. We studied 4 cases with computed tomography evidence of bilateral diencephalic infarctions. Each case began abruptly with hypersomnolent apathy followed by fluctuations from appropriate affect, full orientation, and alertness to labile mood, confabulation, and apathy. Speech varied from hypophonia to normal; handwriting varied from legible script to gross scrawl. Psychological testing revealed poor learning and recall, with low performance scores. In 3 patients the predominant abnormality was in downward gaze.

    Patau syndrome has an incidence of 1/10.000-20.000, the clinical diagnosis being suggested by the triad cleft lip and palate, microphthalmia/anophthalmia and postaxial polydactyly. Most frequent cytogenetic abnormality is free and homogeneous trisomy 13 (80.0%), rarely being detected trisomy mosaics or Robertsonian translocations. The objective of the study was to identify phenotypic features of trisomy 13. The retrospective study was conducted on a trial group of 14 cases diagnosed cytogenetically with trisomy 13 between January 2000 and December 2012 at lasi Medical Genetics Centre. Of the 14 cases, 3 were evaluated pathologically (two aborted foetuses and one stillborn), 8 cases were detected in the neonatal period, and 3 in infancy. Clinical diagnosis was supported by the identification of a model of abnormal development, mainly characterized by: maxillary cleft (lip and palate--5 cases; lip--1 case), ocular abnormalities (microphthalmia/anophthalmia--7 cases; cyclopia--1 case), postaxial polydactyly (7 cases), scalp defects (6 cases), congenital heart anomalies (10 cases, 6 patients with atrial septal defect), complete holoprosencephaly (4 cases), ear abnormalities (11 cases), broad nasal root (10 cases). An important issue in confirming the phenotypic variability of Patau syndrome is that the classic clinical triad was identified only in one case. Patau syndrome is a disease with variable expression and is characterized by a pattern of abnormal prenatal development characterized by facial dysmorphia, polydactyly and severe birth defects (heart, brain) that generate an increased in utero and perinatal mortality.

    Dursun syndrome is a triad of familial primary pulmonary hypertension, leucopenia, and atrial septal defect. Here we demonstrate that mutations in G6PC3 cause Dursun syndrome. Mutations in G6PC3 are known to also cause severe congenital neutropenia type 4. Identification of the genetic basis of Dursun syndrome expands the pre-existing knowledge about the phenotypic effects of mutations in G6PC3. We propose that Dursun syndrome should now be considered as a subset of severe congenital neutropenia type 4 with pulmonary hypertension as an important clinical feature.

    Shwachman-Bodian-Diamond syndrome (OMIM 260400) was identified in 1964 by pediatricians Harry Shwachman, a leader in cystic fibrosis, and Louis K. Diamond, a hematologist, along with pediatrician and morbid anatomist Martin Bodian. Initially the syndrome's clinical presentation included exocrine pancreatic insufficiency (lipomatous replacement of the pancreas) and neutropenia. In 1967 skeletal changes of metaphyseal chondrodysplasia were also described, completing the triad of findings; these abnormalities are present in all affected children and should be viewed as an integral feature of the syndrome, also called Shwachman-Diamond syndrome.

    The Dark Triad (DT) describes a set of three closely related personality traits: Machiavellianism, narcissism, and psychopathy. Mental toughness (MT) refers to a psychological construct combining confidence, commitment, control, and challenge. High MT is related to greater physical activity (PA) and, relative to men, women have lower MT scores. The aims of the present study were 1) to investigate the association between DT, MT, and PA, and 2) to compare the DT, MT, and PA scores of men and women. A total of 341 adults (M=29 years; 51.6% women; range: 18-37 years) took part in the study. Participants completed a series of questionnaires assessing DT, MT, and PA. Machiavellianism, narcissism, and psychopathy were all significantly associated with higher MT scores (rs =0.45, 0.50, and 0.20, respectively). DT traits and MT were associated with more vigorous PA. Compared to men, women participants had lower scores for DT traits (overall score and psychopathy), while no differences were found for MT or PA in both sexes. DT traits, high MT, and vigorous PA are interrelated. This pattern of results might explain why, for instance, successful professional athletes can at the same time be tough and ruthless.

    Background: The National Collegiate Athletic Association (NCAA) has recently highlighted mental health concerns in student athletes, though the incidence of suicide among NCAA athletes is unclear. The purpose of this study was to determine the rate of suicide among NCAA athletes. Hypothesis: The incidence of suicide in NCAA athletes differs by sex, race, sport, and division. Study Design: Retrospective cohort study. Level of Evidence: Level 3. Methods: NCAA Memorial Resolutions list and published NCAA demographic data were used to identify student-athlete deaths and total participant seasons from 2003-2004 through 2011-2012. Deaths were analyzed by age, sex, race, division, and sport. Results: Over the 9-year study period, 35 cases of suicide were identified from a review of 477 student-athlete deaths during 3,773,309 individual participant seasons. The overall suicide rate was 0.93/100,000 per year. Suicide represented 7.3% (35/477) of all-cause mortality among NCAA student athletes. The annual incidence of suicide in male athletes was 1.35/100,000 and in female athletes was 0.37/100,000 (relative risk [RR], 3.7; P < 0.01). The incidence in African American athletes was 1.22/100,000 and in white athletes was 0.87/100,000 (RR, 1.4; P = 0.45). The highest rate of suicide occurred in men’s football (2.25/100,000), and football athletes had a relative risk of 2.2 (P = 0.03) of committing suicide compared with other male, nonfootball athletes. Conclusion: The suicide rate in NCAA athletes appears to be lower than that of the general and collegiate population of similar age. NCAA male athletes have a significantly higher rate of suicide compared with female athletes, and football athletes appear to be at greatest risk. Clinical Relevance: Suicide represents a preventable cause of death, and development of effective prevention programs is recommended. PMID:26502423

    The purpose of this article is to propose a new design for the presentation of the periodic system of the elements. It is a system that highlights the fundamental importance of elements as basic substances rather than elements as simple substances, a distinction that is explained in the article. The proposed table is a variant of the Janet or left-step periodic table. Furthermore the fundamental nature of atomic number triads of elements is put to use in obtaining a new perfect triad by relocating hydrogen among the halogens to give the triad H, F, Cl. The relative virtues of this table, as compared with the medium-long form and the left-step table, are discussed.

    PubMed Central

    2010-01-01

    Background It is well documented that the translation of knowledge into clinical practice is a slow and haphazard process. This is no less true for dental healthcare than other types of healthcare. One common policy strategy to help promote knowledge translation is the production of clinical guidance, but it has been demonstrated that the simple publication of guidance is unlikely to optimise practice. Additional knowledge translation interventions have been shown to be effective, but effectiveness varies and much of this variation is unexplained. The need for researchers to move beyond single studies to develop a generalisable, theory based, knowledge translation framework has been identified. For dentistry in Scotland, the production of clinical guidance is the responsibility of the Scottish Dental Clinical Effectiveness Programme (SDCEP). TRiaDS (Translation Research in a Dental Setting) is a multidisciplinary research collaboration, embedded within the SDCEP guidance development process, which aims to establish a practical evaluative framework for the translation of guidance and to conduct and evaluate a programme of integrated, multi-disciplinary research to enhance the science of knowledge translation. Methods Set in General Dental Practice the TRiaDS programmatic evaluation employs a standardised process using optimal methods and theory. For each SDCEP guidance document a diagnostic analysis is undertaken alongside the guidance development process. Information is gathered about current dental care activities. Key recommendations and their required behaviours are identified and prioritised. Stakeholder questionnaires and interviews are used to identify and elicit salient beliefs regarding potential barriers and enablers towards the key recommendations and behaviours. Where possible routinely collected data are used to measure compliance with the guidance and to inform decisions about whether a knowledge translation intervention is required. Interventions are

The complete form of this syndrome displays all three irregularities. Herein, we report a male case who was admitted to our hospital with symptoms of urinary system infection and persistent constipation 2 years after colostomy operation performed with the indication of rectovestibular fistula and anal atresia, diagnosed as Currarino syndrome based on imaging modalities. In a patient who was admitted because of the presence of anal atresia, in order to preclude potential complications, probable concomitancy of this syndrome should not be forgotten. Early diagnosis is important for the prevention of meningitis, urinary tract infections, and malignant change. PMID:27081429

    Femoroacetabular impingement (FAI) syndrome is one source of hip pain that can limit sport participation among athletes. To summarise the return to sport (RTS) rate for athletes after surgery for FAI syndrome. A computer-assisted search of MEDLINE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and EMBASE databases was performed using keywords related to RTS and RTS at preinjury level (RTS PRE ) of competition for FAI syndrome. The risk of bias in the included studies was assessed using the Methodological Index for Non-Randomized Studies scale. 35 studies (1634 athletes/1828 hips) qualified for analysis. Based on evidence of limited to moderate strength (level 3b to 4 studies), athletes return to sport at preinjury level post surgery for FAI syndrome at a rate of only 74% (67%-81%). Only 37% of studies reported RTS PRE . The mean time from surgery to RTS was 7.0±2.6 months. The mean follow-up postsurgery was 28.1±15.5 months. Professional athletes returned to sport (p=0.0002) (although not the preinjury sport level; p=0.63) at a higher rate than collegiate athletes. Only 14% of studies reported on athletic presurgery and postsurgery athletic performance, which means it is impossible to comment on whether athletes return to their previous level of performance or not. No studies reported on the specific criteria used to permit players to return to sport. 20% of studies reported on career longevity, 51% reported surgical complications and 77% reported on surgical failures. There was limited to moderate evidence that one in four athletes did not return to their previous level of sport participation after surgery for FAI syndrome. Only 37% of the included studies clearly distinguished RTS from RTS PRE . Poor outcome reporting on athletic performance postsurgery makes it difficult to determine to what level of performance these athletes actually perform. Thus, if a player asks a surgeon 'Will I get back to my previous level of performance?' there

    AIM To compare visual efficiency, specifically accom-modation, vergence, and oculomotor functions among athletes and non-athletes. METHODS A cross-sectional study on sports vision screening was used to evaluate the visual skills of 214 elementary students (107 athletes, 107 non-athletes), aged between 13 and 16y. The visual screening assessed visual parameters such as ocular motor alignment, accommodation, and vergence functions. RESULTS Mean visual parameters were compared between age-group matched athletes (mean age 14.82±0.98y) and non-athletes (mean age 15.00±1.04y). The refractive errors of all participants were corrected to maximal attainable best corrected visual acuity of logMAR 0.0. Accommodation function assessment evaluated amplitude of accommodation and accommodation facility. Vergence functions measured the near point of convergence, vergence facility, and distance fusional vergence at break and recovery point. Ocular motor alignment was not statistically significant between both groups. Athletes had a statistically significant amplitude of accommodation for both the right eye (t=2.30, P=0.02) and the left eye (t=1.99, P=0.05). Conversely, non-athletes had better accommodation facility (t=-2.54, P=0.01) and near point of convergence (t=4.39, P<0.001) when compared to athletes. Vergence facility was found to be better among athletes (t=2.47, P=0.01). Nevertheless, non-athletes were significantly better for both distance negative and positive fusional vergence. CONCLUSION Although the findings are still inconclusive as to whether athletes had superior visual skills as compared to non-athletes, it remains important to identify and elucidate the key visual skills needed by athletes in order for them to achieve higher performance in their sports.

    Task-oriented triads were formed into various homogeneous and heterogeneous combinations according to their scores on the n-dominance personality trait of the Edwards Personal Preference Schedule. Five group categories were used. The group task required a consensus decision on each trial. High cooperation and interdependence were reinforced by partially restricting the communication network. Results showed heterogeneous groups significantly better at organizing their group communication processes. They consequently performed the task more efficiently than homogeneous triads.

    Dance is as much a sport as an art form. Sports medicine clinicians seeing dancers in their practice will need to be familiar with the unique characteristics of dance in order to provide proper care. Dance encompasses different forms, which vary in equipment and terminology. The epidemiology of dance injuries has historically focused on ballet, but there is increasing research on other dance forms. Lower extremity and back injuries predominate. Injury prevention, both primary and secondary, is at the heart of dance medicine. Primary prevention includes preseason conditioning, identifying risk factors for injury, and recognizing the female athlete triad. Secondary prevention includes a comprehensive approach to injury rehabilitation, an appreciation for the unique demands of dance, and an understanding of the particulars of the injury being treated. Dancers may have difficulty accessing medical care or following prescribed advice; the proactive clinician will anticipate these situations.

    Despite an increasing number of studies, there is still a lack of knowledge about the unique features that underlie the process in equine assisted social work (EASW). This study aimed to reveal, through qualitative methods, the dyads within the triad that become stronger during the process of EASW, as well as the effect of the participation of the horse on the relationship between the counselor and client. Data were collected through in-depth interviews with nine female self-harming clients aged 15-21 years and eight staff members. The interviews, together with video-recorded human-horse interactions with three staff members and four clients were analyzed, resulting in additional issues answered by these three staff members and four clients in a second interview. Critical dialogues between patterns and fragmentations in the narratives and video-recordings, as well as a dialogue with the participants while they were viewing videos of their own EASW sessions, led to the conclusion that adding a horse qualitatively changes therapeutic relationships in EASW. The different triads consist of different liaisons between actors in the triad, giving rise to unique combinations. The quality of the relationships depends on both the staff and the clients' attachment orientations. Further research is needed to investigate how the degree of emotional connection to the horse affects the impact that horses have on triads in EASW.

    Objective: To prospectively examine the influence of hamstring-to-quadriceps (H:Q) ratio and structural abnormalities on the prevalence of overuse knee injuries among female collegiate athletes. Design and Setting: We used chi-square 2 × 2 contingency tables and the Fischer exact test to examine associations among H:Q ratios, structural abnormalities, and overuse knee injuries. Subjects: Fifty-three apparently healthy women (age = 19.4 ± 1.3 years, height = 167.6 ± 10.1 cm, mass = 65.0 ± 10.0 kg) from National Collegiate Athletic Association Division I women's field hockey (n = 23), soccer (n = 20), and basketball teams (n = 10) volunteered. Measurements: The H:Q ratio was determined from a preseason isokinetic test on a Biodex system at 60°/s and 300°/s. We measured athletes for genu recurvatum and Q-angles with a 14-in (35.56-cm) goniometer. Iliotibial band flexibility was assessed via the Ober test. Results: Ten overuse knee injuries (iliotibial band friction syndromes = 5, patellar tendinitis = 3, patellofemoral syndrome = 1, pes anserine tendinitis = 1) occurred in 9 athletes. The H:Q ratio below the normal range at 300°/s (P = 0.047) was associated with overuse knee injuries, as was the presence of genu recurvatum (P = 0.004). In addition, athletes possessing lower H:Q ratios at 300°/s and genu recurvatum incurred more overuse knee injuries than athletes without these abnormalities (P = 0.001). Conclusions: The presence of genu recurvatum and an H: Q ratio below normal range was associated with an increased prevalence of overuse knee injuries among female collegiate athletes. Further investigation is needed to clarify which preseason screening procedures may identify collegiate athletes who are susceptible to overuse knee injuries. PMID:15496997

  11. Mechanism for acivicin inactivation of triad glutamine amidotransferases.

    PubMed

    Chittur, S V; Klem, T J; Shafer, C M; Davisson, V J

    2001-01-30

    Acivicin [(alphaS,5S)-alpha-amino-3-chloro-4,5-dihydro-5-isoxazoleacetic acid] was investigated as an inhibitor of the triad glutamine amidotransferases, IGP synthase and GMP synthetase. Nucleophilic substitution of the chlorine atom in acivicin results in the formation of an imine-thioether adduct at the active site cysteine. Cys 77 was identified as the site of modification in the heterodimeric IGPS from Escherichia coli (HisHF) by tryptic digest and FABMS. Distinctions in the glutaminase domains of IGPS from E. coli, the bifunctional protein from Saccharomyces cerevisiae (HIS7), and E. coli GMPS were revealed by the differential rates of inactivation. While the ammonia-dependent turnover was unaffected by acivicin, the glutamine-dependent reaction was inhibited with unit stoichiometry. In analogy to the conditional glutaminase activity seen in IGPS and GMPS, the rates of inactivation were accelerated > or =25-fold when a nucleotide substrate (or analogue) was present. The specificity (k(inact)/K(i)app) for acivicin is on the same order of magnitude as the natural substrate glutamine in all three enzymes. The (alphaS,5R) diastereomer of acivicin was tested under identical conditions as acivicin and showed little inhibitory effect on the enzymes indicating that acivicin binds in the glutamine reactive site in a specific conformation. The data indicate that acivicin undergoes a glutamine amidotransferase mechanism-based covalent bond formation in the presence of nucleotide substrates or products. Acivicin and its (alphaS,5R) diastereomer were modeled in the glutaminase active site of GMPS and CPS to confirm that the binding orientation of the dihydroisoxazole ring is identical in all three triad glutamine amidotransferases. Stabilization of the imine-thioether intermediate by the oxyanion hole in triad glutamine amidotransferases appears to confer the high degree of specificity for acivicin inhibition and relates to a common mechanism for inactivation.

    Melkersson Rosenthal syndrome is a very infrequent disease of unknown etiology, chronic and progressive course, with neurocutaneous disease that affects the orofacial innervation and mucocutaneous tissues with non-caseating granulomatous infiltration. Clinically, it is characterized by the diagnostic triad: recurrent edema of lips and/or face; recurrent and alternating acute peripheral facial paralysis and scrotal or geographic tongue. The condition generally presents as oligosymptomatic or monosymptomatic form. Two patients are presented with completed triad and oligosymptomatic form. This recent review published by G. Kayabasoglu et al. states that only 30 patients have been described in the international literature in childhood. So we consider this disease in the differential diagnosis in the presence of acute peripheral facial paralysis and/or lips or facial edema. Sociedad Argentina de Pediatría.

    Parapatellar pain is a common complaint in the active adolescent patient population. Patello-femoral pain syndrome, Osgood-Schlatter disease, Sinding-Larsen-Johansson syndrome, patellar tendinitis, and other stress failure conditions are the primary causes of these parapatellar symptoms. Not all cases of knee discomfort are related to knee pathology. This case study discusses hip pathology as a source of referred knee pain in an 8-year-old male athlete. Care must be taken to evaluate all possible sources of both primary and referred pain in all cases.

    1994-01-01

    Since the inception of NCAA-mandated drug screening in 1986, college athletic trainers have found themselves involved at various levels in institutional drug-screening programs. Several legal, moral, and ethical questions have been raised regarding the drug screening of college athletes, and studies have been conducted to rate athletes' attitudes toward this practice. We examined the responses of certified athletic trainers employed in college settings to ascertain their attitudes toward the drug screening of athletes in general, and, specifically, how they view their role in this process. Surveys were distributed to 500 college athletic trainers randomly selected from the membership database maintained by the National Athletic Trainers' Association, Inc (Dallas, TX). The results of this survey indicate that the majority of athletic trainers feel that their association with the drug-screening process places them in the dual role of police and counselor, but that this relationship does not negatively affect their rapport with their athletes. Opinions regarding the drug-screening process and the importance of education in deterring drug use are somewhat dependent upon the athletic trainer's involvement in the drug-screening process. Athletic trainers possess a stronger desire to serve as resource persons who organize substance abuse education programs rather than serving as administrators of the sampling process. PMID:16558274

    2012-04-01

    The present article suggests the application of a psychodramatic action method for tackling subgroup conflicts in which the direct dialogue between representatives of two opposing subgroups is prepared step by step through an indirect dialogue strategy within two triads, a strategy known as the Double Triad Method (DTM). In order to achieve integration in the group as a whole, it is important that all the members of both subgroups participate actively during the entire process. The first part of the article briefly explores the theoretical background, with a special emphasis on the Phenomenological-Dialectical Personality Model (Phe-Di PModel). In the second part, the DTM procedure is systematically described through its five action stages, each accompanied with 1) a spatial representation of the consecutive actions, 2) some illustrative statements for each stage, and 3) a theoretical interpretation of the dialectically involved personality dimensions in both protagonists. The article concludes with a discussion and suggestions for more extensive applications of the DTM method, including the question of its relationships to Agazarian's functional subgrouping, psychodrama, and sociodrama.

    2000-01-01

    Objective: To describe the evaluation and treatment process for inappropriate functional patterns of neuromuscular activity within the scope of an iliotibial band friction syndrome protocol. Background: Runners with iliotibial band friction syndrome are frequently fitted with orthotic devices to restrict excessive midfoot or rearfoot, or both, motions during the stance phase. These devices may fail to yield favorable results when underlying neuromuscular factors are associated with functional iliotibial band tightening. Differential Diagnosis: Distal biceps femoris tendinitis, popliteal tendinitis, lateral meniscus lesion. Treatment: The athlete's physical examination revealed several patterns of inappropriate neuromuscular activity attributed partly to the prolonged daily wear of beach-type sandals. Modifications of casual footwear and a temporary reduction in training volume were recommended initially to prevent exacerbation of the athlete's condition. Stretching, massage, and soft tissue mobilization were administered in accordance with the athlete's specific needs. The protocol included progressions of nonweightbearing and weightbearing therapeutic exercises. Neuromuscular electric stimulation was incorporated into the protocol to re-educate the role of the first ray within the stance phase of the athlete's walking gait. Uniqueness: Upon stationary examination, this athlete presented with normal lumbar and lower extremity postures. Gait analysis, however, revealed inappropriate dorsiflexion of the great toe during ambulation. Further, the athlete's performances on a series of tests to assess neuromuscular function were substandard. This athlete's response to previous treatment and unique physical findings required a corrective neuromuscular approach that deviates from iliotibial band friction syndrome protocols advocating the use of orthotics. Conclusions: While the role of any single treatment in the athlete's recovery remains unknown, it seems that a

    Objective The Dark Triad (DT) describes a set of three closely related personality traits: Machiavellianism, narcissism, and psychopathy. Mental toughness (MT) refers to a psychological construct combining confidence, commitment, control, and challenge. High MT is related to greater physical activity (PA) and, relative to men, women have lower MT scores. The aims of the present study were 1) to investigate the association between DT, MT, and PA, and 2) to compare the DT, MT, and PA scores of men and women. Methods A total of 341 adults (M=29 years; 51.6% women; range: 18–37 years) took part in the study. Participants completed a series of questionnaires assessing DT, MT, and PA. Results Machiavellianism, narcissism, and psychopathy were all significantly associated with higher MT scores (rs =0.45, 0.50, and 0.20, respectively). DT traits and MT were associated with more vigorous PA. Compared to men, women participants had lower scores for DT traits (overall score and psychopathy), while no differences were found for MT or PA in both sexes. Conclusion DT traits, high MT, and vigorous PA are interrelated. This pattern of results might explain why, for instance, successful professional athletes can at the same time be tough and ruthless.

  1. Resonant triad in boundary-layer stability. Part 1: Fully nonlinear interaction

    NASA Technical Reports Server (NTRS)

    Mankbadi, Reda R.

    1991-01-01

    A first principles theory is developed to study the nonlinear spatial evolution of a near-resonance triad of instability waves in boundary layer transition. This triad consists of a plane wave at fundamental frequency and a pair of symmetrical, oblique waves at the subharmonic frequency. A low frequency, high Reynolds number asymptotic scaling leads to a distinct critical layer where nonlinearity first becomes important; the development of the triad's waves is determined by the critical layer's nonlinear, viscous dynamics. The resulting theory is fully nonlinear in that all nonlinearly generated oscillatory and nonoscillatory components are accounted for. The presence of the plane wave initially causes exponential of exponential growth of the oblique waves. However, the plane wave continues to follow the linear theory, even when the oblique waves' amplitude attains the same order of magnitude as that of the plane wave. A fully interactive stage then comes into effect when the oblique waves exceed a certain level compared to that of the plane wave. The oblique waves react back on the fundamental, slowing its growth rate. The oblique waves' saturation results from their self-interaction - a mechanism that does not require the presence of the plane wave. The oblique waves' saturation level is independent of their initial level, but decreases as the obliqueness angle increases.

  3. Net field-aligned currents observed by Triad

    1975-01-01

    From the Triad magnetometer observation of a step-like level shift in the east-west component of the magnetic field at 800 km altitude, the existence of a net current flowing into or away from the ionosphere in a current layer was inferred. The current direction is toward the ionosphere on the morning side and away from it on the afternoon side. The field aligned currents observed by Triad are considered as being an important element in the electro-dynamical coupling between the distant magnetosphere and the ionosphere. The current density integrated over the thickness of the layer increases with increasing magnetic activity, but the relation between the current density and Kp in individual cases is not a simple linear relation. An extrapolation of the statistical relation to Kp = 0 indicates existence of a sheet current of order 0.1 amp/m even at extremely quiet times. During periods of higher magnetic activity an integrated current of approximately 1 amp/m and average current density of order 0.000001 amp/sq m are observed. The location and the latitudinal width of the field aligned current layer carrying the net current very roughly agree with those of the region of high electron intensities in the trapping boundary.

    2004-01-01

    Faced with unprecedented financial pressures, many nonprofit hospitals today contemplate hooking up with large corporations and converting to for-profit status. In the deals that result, the talk is largely about stock value and the interests of investors. The larger public-interest question of how the conversion will affect the health of community members often receives short shift. Most recently, Triad, an HCA spin-off, has emerged as a major player in the market for faltering nonprofits, zeroing in on institutions all the way from Alaska to North Carolina, and this has advocates worried, because the company can be singularly insensitive to community health care needs. But Triad is also remarkably adept at winning public favor. In this States of Health, we'll look at the broader public policy questions raised by such corporate health ventures, questions that point to the need for stronger oversight and regulatory mechanisms to assure that the public interest is protected in our increasingly market-driven health system.

    2016-01-01

    Rhabdomyolysis is a syndrome characterized by muscle pain, weakness and myoglobinuria and ranges in severity from asymptomatic to life threatening with acute kidney failure. While a common condition in adult populations, it is understudied in pediatrics and the majority of adolescent cases are likely exercise-induced, caused by strenuous exercise in athletes. Recently, in our pediatric sports medicine practice, we have seen numerous cases of late adolescent high school athletes who present with severe muscle pain and were found to have elevated creatine kinase levels. The cases review potential contributing factors including characteristics of the workout, use of supplements, caffeine, medication, and metabolic or genetic predisposition. Treatment for exercised-induced rhabdomyolysis rarely requires more than rehydration. Return to play should be progressive, individualized, and include acclimatization and monitoring of hydration status, though guidelines require further review.

    College student–athletes are at risk for heavy alcohol consumption and related consequences. The present study evaluated the influence of college student and college athlete descriptive norms and levels of athletic identity on drinking and related consequences among incoming college students attending two universities (N = 1119). Prior to the beginning of their first year of college, students indicating high school athletic participation completed assessments of athletic identity, alcohol consumption, drinking-related consequences, and normative perceptions of alcohol use. Estimations of drinking by college students and student–athletes were significantly greater than self-reported drinking. Athletic identity moderated associations among gender, perceived norms, drinking, and related consequences. Athlete-specific norms had a stronger effect on drinking among those reporting higher levels of athletic identity, and higher levels of athletic identity exclusively protected males from experiencing drinking-related consequences. Implications of the role of athletic identity in the development of social norms interventions targeted at high school athletes transitioning to college are discussed. PMID:19095359

    Molecular triad composed of fullerene, porphyrin, and carotene is an artificial analogue of natural photosynthetic system and is considered for applications in solar energy conversion because of its ability to produce long-lived photo-induced charge separated state. The goal of the present multiscale simulation is to understand how the stability of photo-induced charge-separated state in molecular triad is influenced by a polar organic solvent, namely tetrahydrofuran (THF). The multiscale approach is based on combined quantum, classical molecular dynamics, and statistical physics calculations. The quantum chemical calculations were performed on the triad using the second order algebraic diagrammatic perturbation and time-dependent density functional theory. Molecular dynamics simulations were performed on triad in a box of THF solvent with the replica exchange method. The two methods on different length and time scales are bridged through an important sampling technique. We have analyzed the free energy landscape, structural fluctuations, and the long- range electrostatic interactions between triad and solvent molecules. The results suggest that the polarity and re-organization of the solvent is critical in stabilization of charge-separated state in triad. Supported by DOE (DE-FG02-10ER16175)

    Yellow nail syndrome (YNS) is an uncommon disorder characterized by a triad of nail dystrophy, lymphedema, and pleural effusion. It is rare in children and congenital occurrence of YNS has been very rarely described. We report a 2-year-old Arab boy having congenital yellow nail syndrome with mild facial dysmorphism and bilateral conjunctival pigmentation born to consanguineous parents. One of his older siblings had died of nonimmune fetal hydrops (NIFH). The case supports the genetic basis of yellow nail syndrome with a possible relationship to nonimmune fetal hydrops. © 2010 Wiley Periodicals, Inc.

    Researchers have investigated heterosexuals' attitudes toward homosexuals, focusing on factors such as sex, race, religion, education, and contact experiences. However, in the context of sport, this research is deficient. We found no published literature investigating athletic trainers (ATs') attitudes toward lesbian, gay, and bisexual student-athletes (LGB). To determine heterosexual ATs' attitudes toward LGB student-athletes in the National Collegiate Athletic Association. Cross-sectional study. E-mailed survey. A total of 964 ATs employed at member institutions. We measured attitudes using the Attitudes Toward Lesbian, Gay Men, and Bisexuals (ATLGB) Scale. To determine the extent to which sex, religion, and whether having an LGB friend or family member had an effect on ATs' attitudes, we performed analysis of variance. To establish the effect of age on ATs' attitudes, we calculated a Pearson correlation. We used an independent t test to identify differences between ATs who reported working with LGB student-athletes and ATs who did not. With ATLGB score as the dependent factor, a main effect was noted for sex, religion, and having an LGB friend or family member (P < .01 for all comparisons). Age and total score were related (P < .01). A difference was seen in the ATLGB scores between ATs who were aware of LGB student-athletes on their teams and ATs who were not (P < .001). Many ATs hold positive attitudes toward LGB student-athletes, especially females, those who have an LGB friend or family member, and those who are aware of LGB student-athletes. Still, it is important to provide an open environment in the athletic training room for all student-athletes.

    A ferrocene-distyryl BODIPY dyad and a ferrocene-distyryl BODIPY-C(60) triad are synthesized and characterized. Upon photoexcitation at the distyryl BODIPY unit, these arrays undergo photoinduced electron transfer to form the corresponding charge-separated species. Based on their redox potentials, determined by cyclic voltammetry, the direction of the charge separation and the energies of these states are revealed. Femtosecond transient spectroscopic studies reveal that a fast charge separation (k(CS) =1.0×10(10) s(-1)) occurs for both the ferrocene-distyryl BODIPY dyad and the ferrocene-distyryl BODIPY-C(60) triad, but that a relatively slow charge recombination is observed only for the triad. The lifetime of the charge-separated state is 500 ps. Charge recombination of the dyad and triad leads to population of the triplet excited sate of ferrocene and the ground state, respectively.

Soc. Chem. Commun. 1525-1526.) was examined in triads purified from rabbit skeletal muscle. A Ca2+ electrode uptake-release assay was used to determine the size and sensitivity of the IPS3-releasable pool of Ca2+ in isolated triads. Uptake was initiated by 1 mM MgATP, pCa 5.8, pH 7.5 Release was initiated when the free Ca2+ had lowered to pCa approximately 7. We found that 5-25 microM myo-inositol 1,4,5-trisphosphate (IP3), and separately IPS3, consistently released 5-20% of the Ca2+ pool actively loaded into triads. Single channel recording was used to determine if ryanodine receptor Ca2+ release channels were affected by IPS3 at the same myoplasmic Ca2+ and IPS3 concentrations. Open probability of ryanodine receptor Ca2+ release channels was monitored in triads fused to bilayers over long periods (200 s) in the absence and following addition of 30 microM IPS3 to the same channel. At myoplasmic pCa approximately 7, IPS3 had no effect in the absence of MgATP (Po = 0.0094 +/- 0.001 in control and Po = 0.01 +/- 0.006 after IPS3) and slightly increased activity in the presence of 1 mM MgATP (Po = 0.024 +/- 0.03 in control and Po = 0.05 +/- 0.03 after IPS3). Equally small effects were observed at higher myoplasmic Ca2+. The onset of channel activation by IPS3 or IP3 was slow, on the time scale 20-60 s. We suggest that in isolated triads of rabbit skeletal muscle, IP3-induced release of stored Ca2+ is probably not mediated by the opening of Ca2+ release channels. PMID:2168221

  12. Coach-athlete attachment and the quality of the coach-athlete relationship: implications for athlete's well-being.

    This study examined whether athletes' attachment styles with the coach were linked to aspects of the coach-athlete relationship quality and, in turn, whether relationship quality was linked to athletes' well-being. One hundred and ninety-two athletes completed a questionnaire measuring their attachment styles and relationship quality with the coach as well as their feelings of positive affect (PA) and negative affect (NA). Structural equation modelling (SEM) analysis found athletes' avoidant and secure attachment styles to be associated with aspects of coach-athlete relationship quality such as social support, relationship depth, and interpersonal conflict. Interpersonal conflict appeared to play a key role in athletes' PA and NA. From a practical perspective, an understanding of conflict management could provide a resource that allows athletes (and coaches) to enhance the quality of their sporting relationships. Specifically, an awareness of proactive strategies (e.g., steps to clarify expectations) and reactive strategies (e.g., cooperation during the discussion of disagreements) could potentially lead both coaches and athletes to "broaden" their viewpoints and in turn "build" connections that are capable of generating positive emotions including interest, excitement, happiness, and zeal.

    Aspirin sensitivity, asthma, and chronic sinusitis with polyposis comprises the syndrome of Aspirin Triad (AT). The sinusitis associated with this disease is often fulminate and difficult to treat. In order to evaluate the surgical treatment of chronic sinusitis of AT a 17-year retrospective study of 80 patients was performed. Friedman Class III or IV sinus CT scans were present in 73 patients (90%) preoperatively. Twenty-five patients (30.1%) had steroid-dependent asthma and an additional 40 (50%) required intermittent oral steroids for asthma control. All patients underwent bilateral sinus surgery by either a conservative or a radical approach. Patients were followed from 3 weeks to 16 years postoperatively, with an average followup of 3 years. Sixty-eight patients (85%) had significant improvement in their sinus symptoms and 67 (83%) had relief of their asthma. The eight patients (10%) who remained steroid dependent required smaller doses of steroids. Seven patients (8.8%) had nonoperative orbital complications. There was a significant incidence of revision surgery after both conservative and radical sinus procedures. We conclude that surgical treatment by either a conservative or a radical approach controlled the sinusitis in the majority of AT patients, but neither was effective in eliminating the need for subsequent sinus surgery in a significant number of patients with severe sinus disease (Classes III and IV). Control of the sinus disease has a definite beneficial effect on steroid dependency and the need for intermittent oral steroids in managing the asthma in AT. We recommend conservative surgery in the surgical treatment of these patients. AT patients also require close long-term followup with intense medical management of their chronic respiratory inflammation that appears to put them at increased risk for nonoperative complications of their severe sinusitis.

    Disordered eating behavior (DE) and eating disorders (EDs) are of great concern because of their associations with physical and mental health risks and, in the case of athletes, impaired performance. The syndrome originally known as the Female Athlete Triad, which focused on the interaction of energy availability, reproductive function, and bone health in female athletes, has recently been expanded to recognize that Relative Energy Deficiency in Sport (RED-S) has a broader range of negative effects on body systems with functional impairments in both male and female athletes. Athletes in leanness-demanding sports have an increased risk for RED-S and for developing EDs/DE. Special risk factors in aquatic sports related to weight and body composition management include the wearing of skimpy and tight-fitting bathing suits, and in the case of diving and synchronized swimming, the involvement of subjective judgments of performance. The reported prevalence of DE and EDs in athletic populations, including athletes from aquatic sports, ranges from 18 to 45% in female athletes and from 0 to 28% in male athletes. To prevent EDs, aquatic athletes should practice healthy eating behavior at all periods of development pathway, and coaches and members of the athletes' health care team should be able to recognize early symptoms indicating risk for energy deficiency, DE, and EDs. Coaches and leaders must accept that DE/EDs can be a problem in aquatic disciplines and that openness regarding this challenge is important.

    Sudden cardiac death (SCD) in a young athlete represents a dramatic event, and an increasing number of medico-legal cases have addressed this topic. In addition to representing an ethical and medico-legal responsibility, prevention of SCD is directly correlated with accurate eligibility/disqualification decisions, with an inappropriate pronouncement in either direction potentially leading to legal controversy. This review summarizes the common causes of SCD in young athletes, divided into structural (hypertrophic cardiomyopathy, arrhythmogenic cardiomyopathy, congenital coronary artery anomalies, etc.), electrical (Brugada, congenital LQT, Wolf-Parkinson-White syndrome, etc.), and acquired cardiac abnormalities (myocarditis, etc.). In addition, the roles of hereditary cardiac anomalies in SCD in athletes and the effects of a positive result on them and their families are discussed. The medico-legal relevance of pre-participation screening is analyzed, and recommendations from the American Heart Association and European Society of Cardiology are compared. Finally, the main issues concerning the differentiation between physiologic cardiac adaptation in athletes and pathologic findings and, thereby, definition of the so-called gray zone, which is based on exact knowledge of the mechanism of cardiac remodeling including structural or functional adaptions, will be addressed.

    Abstract Activity or exercise-induced leg pain is a common complication among competitive and “weekend warrior” athletes. Shin splints is a term that has been used to describe all lower leg pain as a result of activity. There are many different causes of “shin splints,” one of which is medial tibial stress syndrome, and the treating clinician must be aware of potentially serious causes of activity related leg pain. Restoring proper biomechanics to the entire kinetic chain and rehabilitation of the injured area should be the primary aim of treatment to optimize shock absorption. The role inflammation plays in medial tibial stress syndrome is controversial, but in this case, seemed to be a causative factor as symptomatology was dramatically decreased with the addition of proteolytic enzymes. Medial tibial stress syndrome can be quite difficult to treat and keeping athletes away from activities that will slow healing or aggravate the condition can be challenging. “Active” rest is the best way in which to allow proper healing while allowing the athlete to maintain their fitness.

    OBJECTIVE: To examine college athletic trainers' confidence in helping female athletes who have eating disorders. DESIGN AND SETTING: We mailed a 4-page, 53-item survey to head certified athletic trainers at all National Collegiate Athletic Association Division IA and IAA institutions (N = 236). A 2- wave mailing design was used to increase response rate. SUBJECTS: A total of 171 athletic trainers returned completed surveys for a response rate of 77%. Eleven institutions either did not identify their head athletic trainer or did not have an identifiable mailing address. Two surveys were undeliverable because of incorrect mailing addresses. MEASUREMENTS: The survey consisted of 4 subscales: (1) efficacy expectation, (2) outcome expectation, (3) outcome value, and (4) experience in dealing with eating disorders. Content validity was established by review from a national panel of experts. Reliability ranged from.66 to.73 for the subscales. RESULTS: Although virtually all athletic trainers (91%) had dealt with a female athlete with an eating disorder, only 1 in 4 (27%) felt confident identifying a female athlete with an eating disorder, and only 1 in 3 (38%) felt confident asking an athlete if she had an eating disorder. One in 4 athletic trainers (25%) worked at an institution that did not have a policy on handling eating disorders. Almost all athletic trainers (93%) felt that increased attention needs to be paid to preventing eating disorders among collegiate female athletes. CONCLUSIONS: Collegiate athletic programs are encouraged to develop and implement eating-disorder policies. Continuing education on the prevention of eating disorders among athletes is also strongly recommended.

    Low back pain (LBP) is a common pain syndrome in athletes, responsible for 28% of missed training days/year. Psychosocial factors contribute to chronic pain development. This study aims to investigate the transferability of psychosocial screening tools developed in the general population to athletes and to define athlete-specific thresholds. Data from a prospective multicentre study on LBP were collected at baseline and 1-year follow-up (n=52 athletes, n=289 recreational athletes and n=246 non-athletes). Pain was assessed using the Chronic Pain Grade questionnaire. The psychosocial Risk Stratification Index (RSI) was used to obtain prognostic information regarding the risk of chronic LBP (CLBP). Individual psychosocial risk profile was gained with the Risk Prevention Index - Social (RPI-S). Differences between groups were calculated using general linear models and planned contrasts. Discrimination thresholds for athletes were defined with receiver operating characteristics (ROC) curves. Athletes and recreational athletes showed significantly lower psychosocial risk profiles and prognostic risk for CLBP than non-athletes. ROC curves suggested discrimination thresholds for athletes were different compared with non-athletes. Both screenings demonstrated very good sensitivity (RSI=100%; RPI-S: 75%-100%) and specificity (RSI: 76%-93%; RPI-S: 71%-93%). RSI revealed two risk classes for pain intensity (area under the curve (AUC) 0.92(95% CI 0.85 to 1.0)) and pain disability (AUC 0.88(95% CI 0.71 to 1.0)). Both screening tools can be used for athletes. Athlete-specific thresholds will improve physicians' decision making and allow stratified treatment and prevention.

  6. Being and becoming a psychotherapy supervisor: the crucial triad of learning difficulties.

    PubMed

    Watkins, C Edward

    2013-01-01

    More than 40 years ago eminent psychiatrist Richard Chessick penned a classic, highly prescient psychotherapy supervision paper (that appeared in this journal) in which he identified for supervisors the crucial triad of learning difficulties that tend to confront beginning therapists in their training. These are (a) dealing with the anxiety attendant to the development of psychological mindedness; (b) developing a psychotherapist identity; and (c) developing conviction about the meaningfulness of psychodynamics and psychotherapy. In this paper, I would like to revisit Chessick's seminal contribution about the teaching and learning of psychotherapy and extrapolate his triad of learning difficulties to the process of teaching and learning supervision. The process of being and becoming a psychotherapist has been likened to a developmental journey, and similarly being and becoming a supervisor is increasingly recognized as a developmental journey that is best stimulated by means of didactic and practical experiences (i.e., supervision coursework, seminars, or workshops and the supervision of supervision). In what follows, I would like to explore how Chessick's crucial triad of learning difficulties can be meaningfully extrapolated to and used to inform the supervision training situation. In extrapolating Chessick's triad, beginning supervisors or supervisor trainees can be conceptualized as confronting three critical issues: (a) dealing with the anxiety and demoralization attendant to the development of supervisory mindedness; (b) developing a supervisory identity; and (c) developing conviction about the meaningfulness of psychotherapy supervision. This triadic conceptualization appears to capture nicely core concerns that extend across the arc of the supervisor development process and provides a useful and usable way of thinking about supervisor training and informing it. Each component of the triadic conceptualization is described, and some supervisor education

    Although seatbelts save lives, adolescents may be disproportionately likely to omit their use. Using data from the 1997 Youth Risk Behavior Survey, a national survey of more than 16,000 U.S. public and private high school students, the authors employed a series of logistic regression analyses to examine cross-sectional associations between past year athletic participation and regular seatbelt omission. Controlling for the effects of gender, age, race, parental education, and school urbanicity, student athletes were significantly less likely than nonathletes to report seatbelt omission. Separate gender-specific analyses showed that this effect was significant for girls but only marginally significant for boys; in addition, the effect was strongest for adolescents who participated on three or more school or community sports teams. Possible explanations for the relationship between athletic participation and seatbelt omission, including Jessor's problem behavior syndrome, prosocial sport subcultures, and sensation seeking, are considered.

    Metabolic syndrome is a clustering of symptoms associated with abdominal obesity that demonstrates a high risk for cardiovascular disease and type II diabetes mellitus. To evaluate football linemen in National Collegiate Athletic Association Divisions I, II, and III schools for the presence of metabolic syndrome according to the American Heart Association/National Heart, Lung, and Blood Institute criteria as well as to document other related biomarkers. Cross-sectional descriptive study. Three university locations on the first full day of football camp in early morning. Of 76 football linemen, 70 were able to provide blood samples. Height, mass, blood pressure, upper-body skinfolds, and waist circumference were measured at various stations. Two small venous samples of blood were collected and analyzed in a hospital laboratory for fasting insulin, glucose, high-density lipoprotein, total cholesterol, triglycerides, C-reactive protein, and glycosylated hemoglobin. The last station was a verbal family history for cardiovascular disease and diabetes; also, athletes filled out a nutrition attitudes questionnaire. Of the 70 athletes, 34 were identified as having metabolic syndrome according to measures of blood pressure, waist circumference, fasting glucose, high-density lipoprotein, and triglycerides. The mean total cholesterol-to-high-density lipoprotein cholesterol ratio for the group was 4.95, with 32 participants displaying values higher than 5.0. Twelve volunteers had total cholesterol levels greater than 200 mmol/L, 15 had high levels of C-reactive protein, and 9 had slightly elevated levels of glycosylated hemoglobin. Although athletes might be assumed to be protected from risks of cardiovascular disease, we found a high incidence of metabolic syndrome and other associated adverse biomarkers for heart disease in collegiate football linemen. Early screening, awareness, and intervention may have favorable effects on the overall health outcomes of football linemen.

    McCune-Albright syndrome (MAS) is a non-inherited disorder due to the GNAS1 gene mutation. The syndrome is characterized with the triad of polyostotic fibrous dysplasia, pigmented skin lesions, endocrinopathy, and precocious puberty. We report the case of a 14-year-old boy, presenting with sclerotic type of polyostotic fibrous dysplasia. Radiological methods including plain X-ray film, MR and whole body bone scintigraphy suggested the diagnosis of MAS. MRI provided more directly perceived images and it was more sensitive in demonstrating the lesion: its shape, contents, especially the size of the affected region. Histopathological study and the identification of mutant gene finally confirmed the diagnostic result.

  14. Fitness Testing Athletes

    PubMed Central

    Cumming, Gordon R.

    1970-01-01

    Fitness testing of athletes can be subdivided into tests of body build, strength, aerobic power, and tests specific to the athletic event. World class athletes seem to fall into specific body types for the individual events. The top athlete usually has very little of the endomorphic characteristics and should be lean. Strength testing should be used more frequently as weight and isometric training techniques are used by many athletes and coaches without specific goals. The aerobic power of many national class athletes may be only 10-30 percent above that of the general population, and high values were found only in cyclists and distance runners. It is emphasized that the scores of fitness tests are specific for each test and do not necessarily correlate at all with athletic performance which is also specific. Despite this limitation, fitness tests do have a place in athletics and should be utilized more fully and with more understanding by coaches and athletes. Imagesp48-a PMID:20468546

    The NASA Triad program of the American Geological Institute (AGI) and Arizona State University School of Earth and Space Exploration (ASU SESE) is a three-part effort to promote Earth and space science literacy and STEM education at the national level, funded by NASA through a cooperative agreement starting in 2010. NASA Triad comprises (1) infusion of NASA STEM content into AGI's secondary Earth science curricula; (2) national lead teacher professional development workshops; and (3) an online professional development guide for teachers running NASA STEM workshops. The Triad collaboration draws on AGI's inquiry-based curriculum and teacher professional-development resources and workforce-building programs; ASU SESE's spectrum of research in Mars and Moon exploration, astrobiology, meteoritics, Earth systems, and cyberlearning; and direct access to NASA facilities and dynamic education resources. Triad milestones to date include integration of NASA resources into AGI's print and online curricula and two week-long, national-scale, teacher-leader professional development academies in Earth and space sciences presented at ASU Dietz Museum in Tempe and NASA Johnson Space Flight Center in Houston. Robust front-end and formative assessments of these program components, including content gains, teacher-perceived classroom relevance, teacher-cohort lesson development, and teacher workshop design, have been conducted. Quantitative and qualitative findings from these assessment activities have been applied to identify best and most effective practices, which will be disseminated nationally and globally through AGI and NASA channels.

    2018-05-01

    This paper aims at investigating the effect of bottom slope to the nonlinear triad interactions for irregular waves propagating in shallow water. The physical experiments are conducted in a wave flume with respect to the transformation of waves propagating on three bottom slopes ( β = 1/15, 1/30, and 1/45). Irregular waves with different type of breaking that are mechanically generated based on JONSWAP spectra are used for the test. The obviously different variations of spectra measured on each bottom reveal a crucial role of slope effect in the energy transfer between harmonics. The wavelet-based bispectrum were used to examine the bottom slope effect on the nonlinear triad interactions. Results show that the different bottom slopes which waves are propagated on will cause a significant discrepancy of triad interactions. Then, the discussions on the summed bicoherence which denote the distribution of phase coupling on each frequency further clarify the effect of bottom slope. Furthermore, the summed of the real and imaginary parts of bispectrum which could reflect the intensity of frequency components participating in the wave skewness and asymmetry were also investigated. Results indicate that the value of these parameters will increase as the bottom slope gets steeper.

    2017-01-01

    This study examines the correlation between athletic identity and academic major selection among intercollegiate student-athletes. A thorough review of literature focusing on academic clustering, athletic identity, and academic development leads to the development of two hypotheses - 1) student-athletes with stronger athletic identity will have a declared major of decreased academic rigor; and 2) student-athletes with stronger athletic identity will be more likely to be undecided on their major. Data were collected through a survey administered to Division I, II, and III student-athletes recording academic major and their Athletic Identity Measurement Scale (AIMS). After analyzing the student responses, Hypothesis I is supported, while Hypothesis II is met with some limitation that leads to a lack of statistical significance. Overall, this study sheds light on a connection between academic choice and athletic identity.

    Athletic pubalgia (AP) is a chronic debilitating syndrome that affects many athletes. As a syndrome, AP is difficult to diagnose both with clinical examination and imaging. AP is also a challenge for conservative intervention with randomized controlled trials showing mixed success rates. In other syndromes where clinical diagnosis and conservative treatment have been less than clear, a paradigm has been suggested as a framework for clinical decision making. To propose a new clinical diagnostic and treatment paradigm for the conservative management of AP. Relevant studies were viewed with regard to diagnosis and intervention and where a gap in evidence existed, clinical expertise was used to fill that gap and duly noted. A new paradigm is proposed to assist with clinical diagnosis and non-surgical intervention in patients suffering with AP. The level of evidence supporting this paradigm, according to the SORT taxonomy, is primarily level 2B. Further testing is warranted but following the suggested paradigm should lead to a clearer diagnosis of AP and allow more meaningful research into homogeneous patient populations within the AP diagnostic cluster.

A thorough review of literature focusing on academic clustering, athletic identity, and academic development leads to the development of two hypotheses – 1) student-athletes with stronger athletic identity will have a declared major of decreased academic rigor; and 2) student-athletes with stronger athletic identity will be more likely to be undecided on their major. Data were collected through a survey administered to Division I, II, and III student-athletes recording academic major and their Athletic Identity Measurement Scale (AIMS). After analyzing the student responses, Hypothesis I is supported, while Hypothesis II is met with some limitation that leads to a lack of statistical significance. Overall, this study sheds light on a connection between academic choice and athletic identity. PMID:29170694

    The problem of sudden death of young athletes continues to be actual. Among its reasons, primary electric myocardium diseases along with organic heart troubles (cardiomyopathies, cordites, anomalies of coronary arteries) take an important place. The most frequent variant of channelopathesis long QT syndrome (LQTS). Both inherited and acquired LQTS may be the reason of sudden cardiac death during physical activity and have to be revealed prior to sports admission. LQTS diagnostics in young athletes become problematic due to secondary exercise-related QT prolongation. Physical load test may reveal myocardium electric instability and enhance LQTS diagnostics accuracy without genetic testing. The aim was to study electrophysiological parameters of myocardium repolarization and reveal the signs of electrical instability as predictors of the life-threatening arrhythmias in young athletes during physical exercise test. In conclusion, electrophysiological myocardium parameters during physical exercise test noted to be markers of electrical myocardial instability and in combination with the other Schwartz criteria, was evidenced the inherited or acquired LQTS. QTc prolongation in athletes at the peak of exercise as well as in early recovery period were noted to be additional predictor life-threatening arrhythmias and sudden cardiac death in young athletes

  1. Nonlinear Interaction of Detuned Instability Waves in Boundary-Layer Transition: Resonant-Triad Interaction

    1998-01-01

    The non-equilibrium critical-layer analysis of a system of frequency-detuned resonant-triads is presented using the generalized scaling of Lee. It is shown that resonant-triads can interact nonlinearly within the common critical layer when their (fundamental) Strouhal numbers are different by a factor whose magnitude is of the order of the growth rate multiplied by the wavenumber of the instability wave. Since the growth rates of the instability modes become larger and the critical layers become thicker as the instability waves propagate downstream, the frequency-detuned resonant-triads that grow independently of each other in the upstream region can interact nonlinearly in the later downstream stage. In the final stage of the non-equilibrium critical-layer evolution, a wide range of instability waves with the scaled frequencies differing by almost an Order of (l) can nonlinearly interact. Low-frequency modes are also generated by the nonlinear interaction between oblique waves in the critical layer. The system of partial differential critical-layer equations along with the jump equations are presented here. The amplitude equations with their numerical solutions are given in Part 2. The nonlinearly generated low-frequency components are also investigated in Part 2.

    Background: Two of the most common causes of groin pain in athletes are femoroacetabular impingement (FAI) and athletic pubalgia. An association between the 2 is apparent, but the prevalence of radiographic signs of FAI in patients undergoing athletic pubalgia surgery remains unknown. The purpose of this study was to determine the prevalence of radiologic signs of FAI in patients with athletic pubalgia. Hypothesis: We hypothesized that patients with athletic pubalgia would have a high prevalence of underlying FAI. Study Design: Case series. Level of Evidence: Level 4. Methods: A retrospective review of all patients evaluated at our institution with athletic pubalgia who underwent surgical treatment (ie, for sports hernia) from 1999 to 2011 was performed. The radiographs of patients with athletic pubalgia were reviewed for radiographic signs of FAI. Alpha angles were measured using frog-leg lateral radiographs. Pincer lesions were identified by measuring the lateral center-edge angle and identifying the presence of a “crossover” sign on anteroposterior radiographs. Phone follow-up was performed 2 years or more after the initial sports hernia surgery to evaluate recurrent symptoms. Results: Forty-three patients underwent 56 athletic pubalgia surgeries. Radiographic evidence of FAI was identified in at least 1 hip in 37 of 43 patients (86%). Cam lesions were identified in 83.7% of the population; the alpha angle averaged 66.7° ± 17.9° for all hips. Pincer lesions were present in 28% of the hips. Eight patients had recurrent groin pain, 3 patients had revision athletic pubalgia surgery, and 1 had hip arthroscopy. Conclusion: The study demonstrates a high prevalence of radiographic FAI in patients with athletic pubalgia. Clinical Relevance: Underlying FAI may be a cause of continued groin pain after athletic pubalgia surgery. Patients with athletic pubalgia should be evaluated closely for FAI. PMID:24587869

    Two case reports of high-level athletes with medial tibial stress syndrome (MTSS), 1 an Olympian with an actual stress fracture, are presented. Successful treatment included radial soundwave therapy, pneumatic leg braces, relative rest using an antigravity treadmill, and temporary foot orthoses. Radial soundwave therapy has a high level of evidence for treatment of MTSS. We also present recent evidence of the value of vitamin D assessment. Both patients had a successful outcome with minimal downtime. Finally, a suggested treatment regimen for MTSS is presented. Copyright © 2017 American College of Foot and Ankle Surgeons.

    Objective: To present recommendations to optimize the fluid-replacement practices of athletes. Background: Dehydration can compromise athletic performance and increase the risk of exertional heat injury. Athletes do not voluntarily drink sufficient water to prevent dehydration during physical activity. Drinking behavior can be modified by education, increasing accessibility, and optimizing palatability. However, excessive overdrinking should be avoided because it can also compromise physical performance and health. We provide practical recommendations regarding fluid replacement for athletes. Recommendations: Educate athletes regarding the risks of dehydration and overhydration on health and physical performance. Work with individual athletes to develop fluid-replacement practices that optimize hydration status before, during, and after competition. Imagesp224-a PMID:16558633

    To determine appropriate management of the active individual with infectious mononucleosis (IM), including issues of diagnosis, the determination of splenomegaly, and other measures of disease status, the relationship of the disease to chronic fatigue syndrome (CFS), and the risks of exercise at various points in the disease process. An Ovid/MEDLINE search (January 1996-June 2015) was widely supplemented by "similar articles" found in Ovid/MEDLINE and PubMed, reference lists, and personal files. Clinical diagnoses of IM are unreliable. Traditional laboratory indicators (lymphocytosis, abnormal lymphocytes, and a heterophile-positive slide test) can be supplemented by more sensitive and more specific but also more costly Epstein-Barr antigen determinations. Clinical estimates of splenomegaly are fallible. Laboratory determinations, commonly by 2D ultrasonography, must take account of methodology, the formulae used in calculations and the individual's body size. The SD of normal values matches the typical increase of size in IM, but repeat measurements can help to monitor regression of the disease. The main risks to the athlete are spontaneous splenic rupture (seen in 0.1%-0.5% of patients and signaled by acute abdominal pain) and progression to chronic fatigue, best avoided by 3 to 4 weeks of restricted activity followed by graded reconditioning. A full recovery of athletic performance is usual with 2 to 3 months of conservative management. Infectious mononucleosis is a common issue for young athletes. But given accurate diagnosis and the avoidance of splenic rupture and progression to CFS through a few weeks of restricted activity, long-term risks to the health of athletes are few.

    2018-05-03

    The syndrome Relative Energy Deficiency in Sport (RED-S) is a clinical entity characterized by low energy availability (LEA), which can negatively affect the health and performance of both male and female athletes. The underlying mechanism of RED-S is an inadequacy of dietary energy to support optimal health and performance. This syndrome refers to impaired physiological function including metabolic rate, menstrual function, bone health, immunity, protein synthesis, and cardiovascular health, with psychological consequences which can either precede (through restrictive dietary habits) or result from RED-S. The term RED-S extends beyond the condition termed the "Female Athlete Triad". Formerly known as synchronized swimming, artistic swimming is an Olympic sport requiring a high level of fitness as well as technical skill and artistry. The risk of RED-S is high in artistic swimming as it is an aesthetic, judged sport with an emphasis on a lean physique. RED-S is of significant concern in the sport of artistic swimming because of the potential negative effects on physical and mental health as well as consequences on athletic performance. This paper reviews health and performance consequences associated with LEA resulting in RED-S in artistic swimming. Medical and nutritional considerations specific to artistic swimming are reviewed and methods to help detect and manage RED-S are discussed. Prevention and management of RED-S in this athlete population should be a priority for coaches and the sport medicine professionals working with artistic swimming athletes should utilize the RED-S CAT, a Clinical Assessment Tool for screening and managing RED-S.

    Since its publication in 2016, the report by the Swedish Agency for Health Technology Assessment and Assessment of Social Services on the diagnostic accuracy of the triad for determining traumatic shaking (1) has been criticised, mainly by paediatricians. One repeated criticism has been that the report focused on the triad of symptoms, namely subdural haematoma, retinal haemorrhages and encephalopathy, in cases without signs of impact. This focus has been described by some critics as one that has been created by lawyers to use in court cases and the triad itself has been dismissed as irrelevant and of no practical or clinical use (2-3) This article is protected by copyright.

    Alport syndrome is a rare condition characterized by the clinical triad of nephritic syndrome, sensorineural deafness, and ophthalmological alterations. Herein, we present a rare case of a patient diagnosed with Alport syndrome and bilateral giant macular holes. A 40-year-old woman with a previously unreported mutation in the COL4A4 gene suggestive of autosomal-recessive Alport syndrome presented at our department. The patient exhibited bilateral full-thickness macular holes measuring >1500 µm at their smallest diameters. The very large dimensions of both macular holes were indicative of a bad prognosis regarding hole closure, and a conservative approach was adopted. The patient was maintained on renal substitution therapy, and genetic counseling was offered to other family members. Ophthalmological findings associated to Alport syndrome commonly include anterior lenticonus and dot-and-fleck retinopathy, although giant macular holes can also be associated with this condition. A multidisciplinary approach is crucial in the management of these patients, as Alport syndrome is an inherited systemic basement membrane disease.

    The coach and interdisciplinary sports science and medicine team strive to continually progress the athlete's performance year on year. In structuring training programmes, coaches and scientists plan distinct periods of progressive overload coupled with recovery for anticipated performances to be delivered on fixed dates of competition in the calendar year. Peaking at major championships is a challenge, and training capacity highly individualised, with fine margins between the training dose necessary for adaptation and that which elicits maladaptation at the elite level. As such, optimising adaptation is key to effective preparation. Notably, however, many factors (eg, health, nutrition, sleep, training experience, psychosocial factors) play an essential part in moderating the processes of adaptation to exercise and environmental stressors, for example, heat, altitude; processes which can often fail or be limited. In the UK, the term unexplained underperformance syndrome (UUPS) has been adopted, in contrast to the more commonly referenced term overtraining syndrome, to describe a significant episode of underperformance with persistent fatigue, that is, maladaptation. This construct, UUPS, reflects the complexity of the syndrome, the multifactorial aetiology, and that ‘overtraining’ or an imbalance between training load and recovery may not be the primary cause for underperformance. UUPS draws on the distinction that a decline in performance represents the universal feature. In our review, we provide a practitioner-focused perspective, proposing that causative factors can be identified and UUPS explained, through an interdisciplinary approach (ie, medicine, nutrition, physiology, psychology) to sports science and medicine delivery, monitoring, and data interpretation and analysis.

    Lower leg pain is a common complaint of athletically active individuals, often limiting physical activities. As such, the group of lower leg conditions related to athletic pursuits and physical exercise confer considerable operational implications for the military. Whilst acute injuries to the lower limb are commonly encountered and are clearly of significance, this article focuses instead on chronic conditions related to physical activity. These include insults to bone such as stress fractures and medial tibial stress syndrome, and those related to the soft tissues such as chronic exertional compartment syndrome. In this article we will examine the presentation and management of these conditions.

    2005-08-01

    Although chronic exercise is generally believed to improve the lipidemic profile, it is not clear whether this is due to exercise training or to other determinants such as the usually low body fat of athletes. The aim of the present study was to compare the lipidemic profile of young lean athletes and non-athletes matched for percentage body fat. Fourteen endurance athletes and fourteen sedentary men participated in the study. Participants provided two blood samples at the beginning and end of a 7-d period, during which they recorded physical activity and food intake. Athletes had significantly higher energy expenditure and energy intake but not significantly different macronutrient composition of their diet from non-athletes. No significant differences were found in serum triacylglycerol, total cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol concentrations between groups. These data suggest that athletes and non-athletes with similar body fat do not differ in their lipidemic profiles.

    Objective: To present guidelines for the recognition, prophylaxis, and management of asthma that lead to improvement in the quality of care certified athletic trainers and other heath care providers can offer to athletes with asthma, especially exercise-induced asthma. Background: Many athletes have difficulty breathing during or after athletic events and practices. Although a wide variety of conditions can predispose an athlete to breathing difficulties, the most common cause is undiagnosed or uncontrolled asthma. At least 15% to 25% of athletes may have signs and symptoms suggestive of asthma, including exercise-induced asthma. Athletic trainers are in a unique position to recognize breathing difficulties caused by undiagnosed or uncontrolled asthma, particularly when asthma follows exercise. Once the diagnosis of asthma is made, the athletic trainer should play a pivotal role in supervising therapies to prevent and control asthma symptoms. It is also important for the athletic trainer to recognize when asthma is not the underlying cause for respiratory difficulties, so that the athlete can be evaluated and treated properly. Recommendations: The recommendations contained in this position statement describe a structured approach for the diagnosis and management of asthma in an exercising population. Athletic trainers should be educated to recognize asthma symptoms in order to identify patients who might benefit from better management and should understand the management of asthma, especially exercise-induced asthma, to participate as active members of the asthma care team.

    The current study is the first attempt to examine the association between the Dark Triad of personality (i.e., Machiavellianism, narcissism, and psychopathy) and corruption through a mediator—belief in good luck. Based on Ajzen's theory of planned behavior, we assumed that individuals with Dark Triad would be more likely to engage in corruption as a result of belief in good luck. In Study 1, a set of hypothetical scenarios was used to assess the bribe-offering intention and the corresponding belief in good luck. Results indicated that while the Dark Triad of personality positively predicted bribe-offering intention, it was mediated by the belief in good luck in gain-seeking. In Study 2, we presented participants with some hypothetical scenarios of bribe-taking and the corresponding belief in good luck. Findings revealed that the Dark Triad of personality was positively related to bribe-taking intention; the relationship between narcissism and bribe-taking intention, and that between psychopathy and bribe-taking intention was mediated by the belief in good luck in penalty-avoidance. However, this belief in good luck did not mediate the relationship between Machiavellianism and bribe-taking intention. These results hold while controlling for demographic variables, dispositional optimism, and self-efficacy. Taken together, this study extended previous research by providing evidence that belief in good luck may be one of the reasons explaining why people with Dark Triad are more likely to engage in corruption regardless of the potential outcomes. Theoretical and practical implications were discussed. PMID:27199841

    KIR2DL4 (2DL4, CD158d) is a unique killer cell Ig-like receptor (KIR) expressed on human NK cells, which stimulates cytokine production, but mechanisms regulating its expression and function are poorly understood. By yeast two-hybrid screening, we identified the E3 ubiquitin ligase, Triad3A, as an interaction partner for the 2DL4 cytoplasmic domain. The protein interaction was confirmed in vivo, and Triad3A expression induced polyubiquitylation and degradation of 2DL4. Overexpression of Triad3A selectively abrogated cytokine-producing function of 2DL4, while Triad3A shRNA reversed ubiquitylation and restored cytokine production. Expression of Triad3A in an NK cell line did not affect receptor surface expression, internalization, or early signaling, but significantly reduced receptor turnover and suppressed sustained NF-κB activation. 2DL4 endocytosis was found to be vital to stimulate cytokine production, and Triad3A expression diminished localization of internalized receptor in early endosomes. Our results reveal a critical role for endocytosed 2DL4 receptor to generate sustained NF-κB signaling and drive cytokine production. We conclude that Triad3A is a key negative regulator of sustained 2DL4-mediated NF-κB signaling from internalized 2DL4, which functions by promoting ubiquitylation and degradation of endocytosed receptor from early endosomes. “This is an author-produced version of a manuscript accepted for publication in The Journal of Immunology (The JI).

    Aim of the study was to compare the ANS functioning, as measured by heart rate variability (HRV), in athletes with non-functional overreaching (NFO) and overtraining syndrome (OTS) and in athletes without NFO/OTS. In 43 athletes with NFO/OTS, 40 athletes without NFO/OTS, as well as in 35 sedentary subjects the ANS function was evaluated with the Autonomic Balance Test, based on the HRV analysis of resting heart rate recordings. Results of the study show lower HRV and lower vagal influence along with increased sympathetic cardiovascular control in athletes with non-functional overreaching and particularly in athletes with overtraining, than in highly trained athletes without NFO/OTS. "Stress Response" in athletes with NFO, as well as in some athletes with OTS, showing sympathetic dominance, considered as a sign of physical or mental fatigue and chronic stress, whereas "Total Autonomic Dystonia" in most of the athletes with OTS (67%) reflects more advanced stage of maladaptation associated with depressed regulatory function of the ANS, both sympathetic, as well as vagal influences. Most frequently NFO and OTS were seen in wrestling, which needs further investigation and regular medical monitoring. Thus, results of the study show progression of autonomic imbalance and depression of regulatory function of the autonomic nervous system in athletes with OTS. The cardiac autonomic imbalance observed in overtrained athletes implies changes in HRV and therefore would consider that heart rate variability may provide useful information in detection of overtraining in athletes and can be a valuable adjacent tool for optimising athlete's training program as well as for timely diagnosis and prevention of progression of NFO/OTS.

    BACKGROUND Gradenigo's syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo's syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo's syndrome presenting with meningitis on a background of chronic suppurative otitis media (CSOM) and petrous apicitis (apical petrositis). CASE REPORT A 58-year-old male African American presented with headaches and confusion. Magnetic resonance imaging (MRI) of the head showed petrous apicitis with mastoiditis and abscess formation in the cerebellomedullary cistern (cisterna magna). The case was complicated by the development of palsy of the fourth (trochlear) cranial nerve, fifth (trigeminal) cranial nerve, and sixth (abducens) cranial nerve, with radiological changes indicating infection involving the seventh (facial) cranial nerve, and eighth (vestibulocochlear) cranial nerve. Cerebrospinal fluid (CSF) culture results were positive for Klebsiella pneumoniae, sensitive to ceftriaxone. The patient improved with surgery that included a left mastoidectomy and debridement of the petrous apex, followed by a ten-week course of antibiotics. Follow-up MRI showed resolution of the infection. CONCLUSIONS This report is of an atypical case of Gradenigo's syndrome. It is important to recognize that the classical triad of Gradenigo's syndrome, suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve, may also involve chronic suppurative otitis media (CSOM), which may lead to involvement of other cranial nerves, petrous apicitis (apical petrositis), and bacterial meningitis.

    Photodynamic therapy (PDT) continues to evolve into a mature clinical treatment of a variety of cancer types as well as age-related macular degeneration of the eye. However, there are still aspects of PDT that need to be improved in order for greater clinical acceptance. While a number of new PDT photo-sensitizers, sometimes referred to as second- or third- generation therapeutic agents, are currently under clinical investigation, the direct treatment through the skin of subcutaneous tumors deeper than 5 mm remains problematic. Currently approved PDT porphyrin photo-sensitizers, as well as several modified porphyrins (e.g. chlorins, bacteriochlorins, etc.) that are under clinical investigation can be activated at 630-730 nm, but none above 800 nm. It would be highly desirable if new PDT paradigms could be developed that would allow photo-activation deep in the tissue transparency window in the Near-infrared (NIR) above 800 nm to reduce scattering and absorption phenomena that reduce deep tissue PDT efficacy. Rasiris and MPA Technologies have developed new porphyrins that have greatly enhanced two-photon absorption ( P A ) cross-sections and can be activated deep in the NIR (ca. 780-850 nm). These porphyrins can be incorporated into a therapeutic triad that also employs an small molecule targeting agent that directs the triad to over-expressed tumor receptor sites, and a NIR onephoton imaging agent that allows tracking the delivery of the triad to the tumor site, as well as clearance of excess triad from healthy tissue prior to the start of PDT treatment. We are currently using these new triads in efficacy studies with a breast cancer cell line that has been transfected with luciferase genes that allow implanted tumor growth and post- PDT treatment efficacy studies in SCID mouse models by following the rise and decay of the bioluminescence signal. We have also designed highly absorbing and scattering collagen breast cancer phantoms in which we have demonstrated

    Although seat belts save lives, adolescents may be disproportionately likely to omit their use. Using data from the 1997 Youth Risk Behavior Survey, a national survey of over 16,000 U.S. public and private high school students, we employed a series of logical regression analyses to examine cross-sectional associations between past-year athletic participation and regular seat belt omission. Controlling for the effects of gender, age, race, parental education, and school urbanicity, student athletes were significantly less likely than nonathletes to report seat belt omission. Separate gender-specific analyses showed that this effect was significant for girls but only marginally significant for boys; in addition, the effect was strongest for adolescents who participated on three or more school or community sports teams. Possible explanations for the relationship between athletic participation and seat belt omission, including Jessor’s problem behavior syndrome, prosocial sport subcultures, and sensation seeking, are considered.

    Undergraduate researchers at research universities are often mentored by graduate students or postdoctoral researchers (referred to collectively as “postgraduates”) and faculty, creating a mentoring triad structure. Triads differ based on whether the undergraduate, postgraduate, and faculty member interact with one another about the undergraduate’s research. Using a social capital theory framework, we hypothesized that different triad structures provide undergraduates with varying resources (e.g., information, advice, psychosocial support) from the postgraduates and/or faculty, which would affect the undergraduates’ research outcomes. To test this, we collected data from a national sample of undergraduate life science researchers about their mentoring triad structure and a range of outcomes associated with research experiences, such as perceived gains in their abilities to think and work like scientists, science identity, and intentions to enroll in a PhD program. Undergraduates mentored by postgraduates alone reported positive outcomes, indicating that postgraduates can be effective mentors. However, undergraduates who interacted directly with faculty realized greater outcomes, suggesting that faculty interaction is important for undergraduates to realize the full benefits of research. The “closed triad,” in which undergraduates, postgraduates, and faculty all interact directly, appeared to be uniquely beneficial; these undergraduates reported the highest gains in thinking and working like a scientist.

    The Klippel-Feil syndrome is a congenital malformation of the skull flap involving complex cervical vertebrae and organs, characterized by a classic triad: short neck, limitation of movement of the head due to cervical spine fusion and low hairline in occipital region. It results from an error in the axial skeleton segmentation of the embryo; its incidence is estimated at 1/40,000-42,000 births and predominates in females. The aim of this paper is to describe the clinical picture of a patient with Klippel-Feil syndrome and multiple malformations, including tracheoesophageal fistula, bifid thumb and intracranial lipomas/angiolipomas,that have not been previously described in the syndrome, so it is considered an exceptional finding.

    The next iteration of the Diagnostic and Statistical Manual of Mental Disorders is due for release in May 2013. The current diagnostic criteria for autism are based on a behavioral triad of impairment, which has been helpful for diagnosis and identifying the need for intervention, but is not useful with regard to developing interventions. Revised diagnostic criteria are needed to better inform research and therapeutic intervention. This article examines the research underpinning the behavioral triad of impairment to consider alternative explanations and a more useful framing for diagnosis and intervention. Contemporary research and literature on autism were used in this study. It is proposed that the cognitive processing triad of impaired abstraction, impaired theory of mind, and impaired linguistic processing become the triad of impairment for autism in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders. These are investigable at the diagnostic level and can usefully inform intervention. Further, in addressing the debate on whether restrictive and repetitive behavior should remain central to diagnosis or be replaced by a deficit in imagination, the authors argue that both behavioral manifestations are underpinned by impaired abstraction. © 2012 Wiley Periodicals, Inc.

    A challenge in the computational design of enzymes is that multiple properties must be simultaneously optimized -- substrate-binding, transition state stabilization, and product release -- and this has limited the absolute activity of successful designs. Here, we focus on a single critical property of many enzymes: the nucleophilicity of an active site residue that initiates catalysis. We design proteins with idealized serine-containing catalytic triads, and assess their nucleophilicity directly in native biological systems using activity-based organophosphate probes. Crystal structures of the most successful designs show unprecedented agreement with computational models, including extensive hydrogen bonding networks between the catalytic triad (or quartet) residues, and mutagenesis experiments demonstrate that these networks are critical for serine activation and organophosphate-reactivity. Following optimization by yeast-display, the designs react with organophosphate probes at rates comparable to natural serine hydrolases. Co-crystal structures with diisopropyl fluorophosphate bound to the serine nucleophile suggest the designs could provide the basis for a new class of organophosphate captures agents. PMID:24705591

    The purpose of this case report was to present a case of groin pain in a pole vault athlete describing the biomechanical features of the injury`s mechanism, acute medical management, and its successful rehabilitation. A 22-year-old professional pole-vaulter sustained an injury during a regular training session. The athlete reported significant left lower abdominal and left proximal adductor discomfort in all activities, including basic trunk motion when moving in bed, sit to stand, and walking, and was unable to return to the regular training. Clinical evaluation and imaging studies addressed the injury to a case of adductor-related groin pain associated with pubic symphysis degeneration. Treatment consisted of an exercise-based therapeutic protocol based on trunk and core muscle strengthening and stability program, with progressive motor and functional demands. Significant improvements in the overall clinical findings and functional outcomes were reported after 52 days of intervention when the athletes returned to his full athletic activity. These results suggest that an appropriate rehabilitation program, focused on trunk and core musculature stability exercise addressing to sport-related specific demands, should be considered as an optimal conservative method in the multidisciplinary approach for treatment of groin pain and prior to any surgical intervention.

    Female athletes may be at greater risk for disordered eating than their nonathletic peers, but the psychological antecedents of this dysfunctional behavior in athletes have yet to be elucidated. The objective of this study was to develop an athletics-oriented measure of psychological predictors of disordered eating and to test its initial reliability and validity. Female athletes from 3 National Collegiate Athletics Association (NCAA) Division I universities completed the ATHLETE, a written questionnaire designed to assess psychosocial factors associated with disordered eating in athletes. Five distinct and internally consistent factors (Drive for Thinness and Performance, Social Pressure on Eating, Performance Perfectionism, Social Pressure on Body Shape, and Team Trust) were positively associated with and predictive of disordered eating behaviors in female athletes. The ATHLETE is a reliable and valid measure of psychological predictors of disordered eating in athletics and will be useful in studying the etiology of disordered eating in female athletes.

    KILT syndrome is a rare condition composing the triad of kidney and inferior vena cava anomaly and extensive venous thrombosis. We present a case of newly diagnosed KILT syndrome in a 41-years-old gentleman presenting with loin pain and fever. Reviewing previous case reports, KILT syndrome is usually an incidental finding on imaging studies and there is a wide scope of initial clinical presentations. However, recent evidence suggests IVC anomaly may have caused subsequent renal hypoplasia. Identification of the underlying etiology may be helpful in planning early vascular intervention to treat the condition.

    Cough is a common symptom experienced by athletes, particularly after exercise. We performed a systematic review to assess the following in this population: (1) the main causes of acute and recurrent cough, either exercise-induced or not, (2) how cough is assessed, and (3) how cough is treated in this population. From the systematic review, suggestions for management were developed. This review was performed according to the CHEST methodological guidelines and Grading of Recommendations Assessment, Development and Evaluation framework until April 2015. To be included, studies had to meet the following criteria: participants had to be athletes and adults and adolescents aged ≥ 12 years and had to complain of cough, regardless of its duration or relationship to exercise. The Expert Cough Panel based their suggestions on the data extracted from the review and final grading by consensus according to a Delphi process. Only 60 reports fulfilled the inclusion criteria, and the results of our analysis revealed only low-quality evidence on the causes of cough and how to assess and treat cough specifically in athletes. Although there was no formal evaluation of causes of cough in the athletic population, the most common causes reported were asthma, exercise-induced bronchoconstriction, respiratory tract infection (RTI), upper airway cough syndrome (UACS) (mostly from rhinitis), and environmental exposures. Cough was also reported to be related to exercise-induced vocal cord dysfunction among a variety of less common causes. Although gastroesophageal reflux disease (GERD) is frequent in athletes, we found no publication on cough and GERD in this population. Assessment of the causes of cough was performed mainly with bronchoprovocation tests and suspected disease-specific investigations. The evidence to guide treatment of cough in the athlete was weak or nonexistent, depending on the cause. As data on cough in athletes were hidden in a set of other data (respiratory

    Tumors drive blood vessel growth to obtain oxygen and nutrients to support tumor expansion, and they also can induce lymphatic vessel growth to facilitate fluid drainage and metastasis. These processes have generally been studied separately, so that it is not known how peritumoral blood and lymphatic vessels grow relative to each other. The murine B16-F10 melanoma and chemically-induced squamous cell carcinoma models were employed to analyze large red-colored vessels growing between flank tumors and draining lymph nodes. Immunostaining and microscopy in combination with dye injection studies were used to characterize these vessels. Each peritumoral red-colored vessel was found to consist of a triad of collecting lymphatic vessel, vein, and artery, that were all enlarged. Peritumoral veins and arteries were both functional, as detected by intravenous dye injection. The enlarged lymphatic vessels were functional in most mice by subcutaneous dye injection assay, however tumor growth sometimes blocked lymph drainage to regional lymph nodes. Large red-colored vessels also grew between benign papillomas or invasive squamous cell carcinomas and regional lymph nodes in chemical carcinogen-treated mice. Immunostaining of the red-colored vessels again identified the clustered growth of enlarged collecting lymphatics, veins, and arteries in the vicinity of these spontaneously arising tumors. Implanted and spontaneously arising tumors induce coordinate growth of blood and lymphatic vessel triads. Many of these vessel triads are enlarged over several cm distance between the tumor and regional lymph nodes. Lymphatic drainage was sometimes blocked in mice before lymph node metastasis was detected, suggesting that an unknown mechanism alters lymph drainage patterns before tumors reach draining lymph nodes.

However, most researchers examining this topic have investigated the perspectives of those who are currently employed rather than those who are preparing to enter the profession. To evaluate female athletic training students' perceptions of motherhood and retention. Qualitative study. Athletic training education program. A total of 18 female athletic training students volunteered to participate. They were enrolled in 1 Commission on Accrediting Athletic Training Education-accredited athletic training program and represented 3 levels of academic STUDY. The participants responded to a series of questions related to work-life balance and retention in athletic training. Analysis of the data followed a general inductive process. Credibility was established by interpretive member checks and peer review. The first theme, clinical setting, speaks to the belief that work-life balance and retention in athletic training require an employment setting that fosters a family-friendly atmosphere and a work schedule (including travel) that allows for time at home. The second theme, mentorship, reflects the acknowledgment that a female mentor who is successful in balancing the roles of mother and athletic trainer can serve as a role model. The final theme, work-life balance strategies, illustrates the need to have a plan in place to meet the demands of both home and work life. A female athletic trainer who is successfully balancing her career and family responsibilities may be the most helpful factor in retention, especially for female athletic training students. Young professionals need to be educated on the importance of developing successful work-life balance strategies, which can be helpful in reducing attrition from the profession.

    Nearly all patients following fractures of bones develop sub-clinical form of fat embolism but the classical form of fat embolism syndrome (FES) presents with triad of respiratory, neurologic and dermal manifestations. Non-traumatic conditions can also have fat embolism, but the incidence is very low. The diagnosis is mainly clinical supported by laboratory and radiological finding. Treatment is mainly supportive with early stabilization of fractured bones. In most cases, prognosis is good if the condition is detected and treated early. High index of suspicion in polytrauma patient is the key to early diagnosis of this condition. This report describes two cases of FES, the second case being fulminant fat embolism with added mortality.

  4. Strong contributions from vertical triads to helix-partner preferences in parallel coiled coils.

    Pairing preferences in heterodimeric coiled coils are determined by complementarities among side chains that pack against one another at the helix-helix interface. However, relationships between dimer stability and interfacial residue identity are not fully understood. In the context of the "knobs-into-holes" (KIH) packing pattern, one can identify two classes of interactions between side chains from different helices: "lateral", in which a line connecting the adjacent side chains is perpendicular to the helix axes, and "vertical", in which the connecting line is parallel to the helix axes. We have previously analyzed vertical interactions in antiparallel coiled coils and found that one type of triad constellation (a'-a-a') exerts a strong effect on pairing preferences, while the other type of triad (d'-d-d') has relatively little impact on pairing tendencies. Here, we ask whether vertical interactions (d'-a-d') influence pairing in parallel coiled-coil dimers. Our results indicate that vertical interactions can exert a substantial impact on pairing specificity, and that the influence of the d'-a-d' triad depends on the lateral a' contact within the local KIH motif. Structure-informed bioinformatic analyses of protein sequences reveal trends consistent with the thermodynamic data derived from our experimental model system in suggesting that heterotriads involving Leu and Ile are preferred over homotriads involving Leu and Ile.

    The medial tibial stress syndrome is a symptom complex seen in athletes who complain of exercise-induced pain along the distal posterior-medial aspect of the tibia. Intramuscular pressures within the posterior compartments of the leg were measured in 12 patients with this disorder. These pressures were not elevated and therefore this syndrome is a not a compartment syndrome. Available information suggests that the medial tibial stress syndrome most likely represents a periostitis at this location of the leg.

    Based on social-learning and self-determination motivational theories, the purpose of this study was to determine the sources of motivation in youth and young adults with intellectual disability (ID) who participate in Special Olympics (SO) competitions and those of typically developed (TD) age- and activity-matched athletes. A convenience sample of 63 SO (25 females and 38 males) and 59 TD (16 females and 43 males) athletes was retrieved through communication with local club coaches. Three sub-groups of SO athletes were identified based on disability, including non specified intellectual disability (NSID=39), Down syndrome (DS=17), and Autism (Aut=7). Mean SO and TD athlete ages were 20.35 (SD=7) and 18.8 (SD=8), respectively. For analysis purposes four age groups were created (<15, 15-17, 18-20, >20 years). Participants completed the 13-item, two-factor Task and Ego Orientation in Sport Questionnaire (TEOSQ) and a 16-item four-factor abridged version of the Sport Motivation Scale (SMS). SO and TD athletes were active in swimming (54 and 48, respectively) and basketball (9 and 11, respectively). Groups with and without ID were compared by means of t-tests in the dichotomized variables gender and activity, as well as by 1-way ANOVA with Tukey HSD post hoc comparisons across disability and age groups. Gender distribution was the same in both groups. Participants with DS and NSID scored significantly higher than TD athletes in most motivational scales. Participants with ID increased their external motivation with increasing age, while a reversed pattern was observed in TD. In summary, significant differences between motivational patterns of SO athletes with ID and TD athletes can be observed. These differences should be considered when developing training and competition programs. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Background An increasing number of sporting bodies report unacceptably high levels of false-positive ECGs when undertaking pre-participation cardiac screening. To address this issue, modified ECG interpretation criteria have become available for use within athletes. Objective This study assessed the accuracy of the new 2014 ‘Refined Criteria’ against the 2013 Seattle Criteria and the 2010 European Society of Cardiology (ESC) recommendations in a cohort of Arabic, black and Caucasian athletes. Methods 2491 male athletes (1367 Arabic, 748 black and 376 Caucasian) undertook pre-participation screening including a 12-lead ECG, with further investigation(s) upon indication. Results Ten athletes (0.4%) were identified with cardiac pathology; seven with hypertrophic cardiomyopathy (HCM; five black and two Arabic) and three Arabs with Wolff–Parkinson–White syndrome (WPW). All three ECG criteria were 100% sensitive identifying all cases of HCM and WPW. The 2014 Refined Criteria reduced (p<0.0001) the prevalence of an abnormal ECG to 5.3% vs 11.6% (Seattle Criteria) and 22.3% (2010 ESC recommendations). The 2014 Refined Criteria significantly (p<0.0001) improved specificity (94.0%) across all ethnicities compared with the Seattle Criteria (87.5%) and ESC recommendations (76.6%). Black athletes continue to present a higher prevalence (p<0.0001) of abnormal ECGs compared with Arabic and Caucasian athletes (10% vs 3.6% and 2.1%). Conclusions The 2014 Refined Criteria for athlete ECG interpretation outperformed both the 2013 Seattle Criteria and the 2010 ESC recommendations by significantly reducing the number of false-positive ECGs in Arabic, black and Caucasian athletes while maintaining 100% sensitivity for serious cardiac pathologies.

    The spin chemistry of photoinduced charge-separated (CS) states of three triads comprising one or two triarylamine donors, a cyclometalated iridium complex sensitizer and a naphthalene diimide (NDI) acceptor, was investigated by transient absorption spectroscopy in the ns-μs time regime. Strong magnetic-field effects (MFE) were observed for two triads with a phenylene bridge between iridium complex sensitizer and NDI acceptor. For these triads, the lifetimes of the CS states increased from 0.6 μs at zero field to 40 μs at about 2 T. Substituting the phenylene by a biphenyl bridge causes the lifetime of the CS state at zero field to increase by more than 2 orders of magnitude (τ = 79 μs) and the MFE to disappear almost completely. The kinetic MFE was analyzed in the framework of a generalized Hayashi-Nagakura scheme describing coherent (S, T0 ↔ T±) as well as incoherent (S, T0 ⇌ T±) processes by a single rate constant k±. The magnetic-field dependence of k± of the triads with phenylene bridge spans 2 orders of magnitude and exhibits a biphasic behavior characterized by a superposition of two Lorentzians. This biphasic MFE is observed for the first time and is clearly attributable to the coherent (B < 10 mT) and incoherent (10 mT < B < 2 T) domains of spin motion induced by isotropic and anisotropic hyperfine coupling. The parameters of both domains are well understood in terms of the structural properties of the two triads, including the effect of electron hopping in the triad with two donor moieties. The kinetic model also accounts for the reduction of the MFE on reducing the rate constant of charge recombination in the triad with the biphenyl bridge.

    Sudden cardiac death is the leading cause of death in athletes. Evidence on current sudden cardiac death prevention through preparticipation history, physicals, and noninvasive cardiovascular diagnostics has demonstrated a low sensitivity for detection of athletes at high risk of sudden cardiac death. Data are lacking on automated external defibrillator programs specifically initiated to respond to rare dysrhythmia in younger, relatively low-risk populations. Surveys were mailed to the head athletic trainers of all National Collegiate Athletic Association Division I athletics programs listed in the National Athletic Trainers' Association directory. In all, 303 surveys were mailed; 186 departments (61%) responded. Seventy-two percent (133) of responding National Collegiate Athletic Association Division I athletics programs have access to automated external defibrillator units; 54% (101) own their units. Proven medical benefit (55%), concern for liability (51%), and affordability (29%) ranked highest in frequency of reasons for automated external defibrillator purchase. Unit cost (odds ratio = 1.01; 95% confidence interval, 1.01-1.0), donated units (odds ratio = 1.92; confidence interval, 3.66-1.01), institution size (odds ratio =.0001; confidence interval, 1.3 E-4 to 2.2E-05), and proven medical benefit of automated external defibrillators (odds ratio = 24; confidence interval, 72-8.1) were the most significant predictors of departmental defibrillator ownership. Emergency medical service response time and sudden cardiac death event history were not significantly predictive of departmental defibrillator ownership. The majority of automated external defibrillator interventions occurred on nonathletes. Many athletics medicine programs are obtaining automated external defibrillators without apparent criteria for determination of need. Usage and maintenance policies vary widely among departments with unit ownership or access. Programs need to approach the issue of unit

    Allergic sensitization and diseases have been reported to have a very high and increasing prevalence in elite athletes. Over 80% of allergic athletes are poly-sensitized. This study aims at evaluating the potential diagnostic added value of a microarray technology (ImmunoCAP ISAC, Phadia AB [at present Thermo Fisher Scientific] Uppsala, Sweden which detects IgE antibodies to specific or cross-reacting allergen components. Seventy-two poly-sensitized athletes according to skin prick test (SPT) with different allergic phenotypes (asthma n = 19; rhino-conjunctivitis n = 20; food allergy and/or oral allergy syndrome n = 13; no clinical symptoms n = 20) and two different control populations (20 poly-sensitized sedentary subjects with respiratory allergy and 20 healthy athletes with negative SPT) were studied for detecting specific IgE (sIgE) both to allergen extracts (ImmunoCAPsIgE) and to allergen components (ImmunoCAP ISAC). ImmunoCAP ISAC detected the presence of sIgE in 90% of poly-sensitized athletes--in 96% with symptoms and in 75% without symptoms--and in 100% of allergic controls. The pattern of positivity towards the 103 components tested differed from subject to subject, even in those with the same sensitization to allergen extract SPT or sIgE. Based on the ISAC results, poly-sensitized athletes were classified into the following prototypical patterns, differently represented in the clinical phenotypes studied (P = 0.03): (1) One single predominant specific allergen positivity; (2) sIgE to two or more non-cross-reacting allergens; (3) sIgE to cross-reacting allergens; and (4) sIgE to components potentially responsible for severe allergic reactions. The ImmunoCAP ISAC represents a useful additional tool for diagnosis and management of poly-sensitized athletes. © 2012 John Wiley & Sons A/S.

    In overtrained athletes, several signs and symptoms have been associated with the imbalance between training and recovery. However, reliable diagnostic markers for distinguishing between well-trained, overreached (OR) and overtrained (OT) athletes are lacking. A hallmark feature of overtraining syndrome (OTS) is the inability to sustain intense exercise and recover for the next training or competition session. We therefore devised a test protocol utilizing two bouts of maximal work. With this test protocol we tried to establish a difference in hormonal responses between the training status of T and OR athletes. Seven well-trained cyclists participated in this study and were tested before and after a training camp. We also present the data of one OT motocross athlete who was clinically diagnosed as overtrained. All athletes performed two maximal exercise tests separated by 4 h. Blood was analyzed for cortisol, adrenocorticotrophic hormone (ACTH), growth hormone and prolactin (PRL). Performance decreased by 6% between the first and the second exercise test in the OR group and by 11% in the OT subject. Moreover, during the second exercise test there were more marked differences between the T and OR athletes; in particular, the OT subject did not show an increase in some of the hormonal responses. PRL increased only by 14% in the OT subject's second test and there was a 7% decrease in ACTH. The two exercise approach enables us to detect subtle performance decrements that will not be identified by one exercise trigger. The hormonal responses to the second exercise test were different between the T and OR athletes (the increase in the T group was higher than in the OR that was higher than in the OT). The results of the case presentation of an overtrained athlete provide evidence of an altered and dysfunctional hypothalamic-pituitary axis response to two bouts of maximal exercise. These findings can be used to develop markers for diagnosis of OTS and to begin to address

    Overtraining syndrome is a condition of maladapted physiology in the setting of excessive exercise without adequate rest. The exact etiology and pathogenesis are unknown and being investigated. Symptoms are multisystem in nature and often representative of underlying hormonal, immunologic, neurologic, and psychologic disturbances. Unfortunately, systematic review of the literature does not clearly direct diagnosis, management, or prevention. However, given the severity of symptoms and impairment to quality of life, prevention of overtraining syndrome should be considered by all who interact with endurance athletes. This article will provide suggestions for management of at-risk athletes despite absence of validated diagnostic tests and preventative measures. PMID:27660501

    OBJECTIVE We hypothesized that, despite increased activity, bone density would be low in athletes with amenorrhea, compared with athletes with eumenorrhea and control subjects, because of associated hypogonadism and would be associated with a decrease in bone formation and increases in bone-resorption markers. METHODS In a cross-sectional study, we examined bone-density measures (spine, hip, and whole body) and body composition by using dual-energy radiograph absorptiometry and assessed fasting levels of insulin-like growth factor I and bone-turnover markers (N-terminal propeptied of type 1 procollagen and N-telopeptide) in 21 athletes with amenorrhea, 18 athletes with eumenorrhea, and 18 control subjects. Subjects were 12 to 18 years of age and of comparable chronologic and bone age. RESULTS Athletes with amenorrhea had lower bone-density z scores at the spine and whole body, compared with athletes with eumenorrhea and control subjects, and lower hip z scores, compared with athletes with eumenorrhea. Lean mass did not differ between groups. However, athletes with amenorrhea had lower BMI z scores than did athletes with eumenorrhea and lower insulin-like growth factor I levels than did control subjects. Levels of both markers of bone turnover were lower in athletes with amenorrhea than in control subjects. BMI z scores, lean mass, insulin-like growth factor I levels, and diagnostic category were important independent predictors of bone mineral density z scores. CONCLUSIONS Although they showed no significant differences in lean mass, compared with athletes with eumenorrhea and control subjects, athletes with amenorrhea had lower bone density at the spine and whole body. Insulin-like growth factor I levels, body-composition parameters, and menstrual status were important predictors of bone density. Follow-up studies are necessary to determine whether amenorrhea in athletes adversely affects the rate of bone mass accrual and therefore peak bone mass. PMID:18519482

    This review focuses on research that specifically highlights the constructs, paradigms, and factors that impact the end-of-athletic-career transition. However, the majority of the research conducted around this topic is established outside of the United States and regarding professional athletes. The National Collegiate Athletic Association (NCAA) is one of the most dominant athletic institutions in the world, and arguably transitions the most end-of-athletic-career athletes per year, and minimal research exists on this specific collegiate athletic population. The purpose of this review is to review the existent literature on this topic and highlight the leading research and components impacting athletes during the end-of-athletic-career transition in order to inform future research and practices with the college athletics population. This review utilizes a Client Oriented Practical Evidence Search question as an Evidence Based Practice approach to guide the literature search and literature review process while identifying the leading research contributing to end-of-athletic-career transition. Following rigorous search criteria, a total of 14 articles were included in the literature review. The selected articles identified central constructs impacting the athletic career transition process, including retirement planning, identity loss, coping skills, and support systems. Additional research is warranted in the United States, particularly with the NCAA collegiate athletes in order to better understand the end-of-athletic-career transition process, as well as instituting interventions to increase resilience in college senior NCAA athletes transitioning out of sport.

    The Dark Triad traits-narcissism, Machiavellianism and psychopathy-have been found to be associated with intra- or interpersonal deception production frequency. This cross-sectional study ( N = 207) investigated if the Dark Triad traits are also associated with deception detection accuracy, as implicated by the recent conception of a deception-general ability. To investigate associations between maladaptive personality space and deception, the PID-5 maladaptive personality traits were included to investigate if besides Machiavellianism, Detachment is negatively associated with response bias. Finally, associations between the Dark Triad traits, Antagonism, Negative Affectivity and confidence judgments were investigated. Participants watched videos of lying vs. truth-telling senders and judged the truthfulness of the statements. None of the Dark Triad traits was found to be associated with the ability to detect deception. Detachment was negatively associated with response bias. Psychopathy was associated with global confidence judgments. The results provide additional support that dark and maladaptive personality traits are associated with judgmental biases but not with accuracy in deception detection. The internal consistencies of 4 of the 8 subscales of the used personality short scales were only low and nearly sufficient (αs =0.65-0.69).

  7. Dusting off the epidemiological triad: could it work with obesity?

    Egger, G; Swinburn, B; Rossner, S

    2003-05-01

    The search for effective ways of dealing with obesity has centred on biological research and clinical management. However, obesity needs to be conceptualized more broadly if the modern pandemic is to be arrested. The epidemiological triad (hosts, agent/vectors and environments) has served us well in dealing with epidemics in the past, and may be worth re-evaluating to this end. Education, behaviour change and clinical practices deal predominantly with the host, although multidisciplinary practices such as shared-care might also be expected to impact on other corners of the triad. Technology deals best with the agent of obesity (energy imbalance) and it's vectors (excessive energy intake and/or inadequate energy expenditure), and policy and social change are needed to cope with the environment. The value of a broad model like this, rather than specific isolated approaches, is that the key players such as legislators, health professionals, governments and industry can see their roles in attenuating and eventually reversing the epidemic. It also highlights the need to intervene at all levels in obesity control and reduces the relevance of arguments about nature vs. nurture.

  8. The effect of structural changes on charge transfer states in a light-harvesting carotenoid-diaryl-porphyrin-C{sub 60} molecular triad

    We present a detailed study of charge transfer (CT) excited states for a large number of configurations in a light-harvesting Carotenoid-diaryl-Porphyrin-C{sub 60} (CPC{sub 60}) molecular triad. The chain-like molecular triad undergoes photoinduced charge transfer process exhibiting a large excited state dipole moment, making it suitable for application to molecular-scale opto-electronic devices. An important consideration is that the structural flexibility of the CPC{sub 60} triad impacts its dynamics in solvents. Since experimentally measured dipole moments for the triad of ∼110 D and ∼160 D strongly indicate a range in structural variability in the excited state, studying the effect of structural changesmore » on the CT excited state energetics furthers the understanding of its charge transfer states. We have calculated the variation in the lowest CT excited state energies by performing a scan of possible variation in the structure of the triad. Some of these configurations were generated by incrementally scanning a 360° torsional (dihedral) twist at the C{sub 60}-porhyrin linkage and the porphyrin-carotenoid linkage. Additionally, five different CPC{sub 60} conformations were studied to determine the effect of pi-conjugation and particle-hole Coulombic attraction on the CT excitation energies. Our calculations show that configurational changes in the triad induces a variation of ∼0.6 eV in CT excited state energies in the gas-phase. The corresponding calculated excited state dipoles show a range of 47 D–188 D. The absorption spectra and density of states of these structures show little variation except for the structures where the porphyrin and aryl conjugation is changed.« less

  10. Sleep and Athletic Performance.

    PubMed

    Watson, Andrew M

    Sleep is an essential component of health and well-being, with significant impacts on physical development, emotional regulation, cognitive performance, and quality of life. Along with being an integral part of the recovery and adaptive process between bouts of exercise, accumulating evidence suggests that increased sleep duration and improved sleep quality in athletes are associated with improved performance and competitive success. In addition, better sleep may reduce the risk of both injury and illness in athletes, not only optimizing health but also potentially enhancing performance through increased participation in training. Despite this, most studies have found that athletes fail to obtain the recommended amount of sleep, threatening both performance and health. Athletes face a number of obstacles that can reduce the likelihood of obtaining proper sleep, such as training and competition schedules, travel, stress, academic demands, and overtraining. In addition, athletes have been found to demonstrate poor self-assessment of their sleep duration and quality. In light of this, athletes may require more careful monitoring and intervention to identify individuals at risk and promote proper sleep to improve both performance and overall health. This review attempts to highlight the recent literature regarding sleep issues in athletes, the effects of sleep on athletic performance, and interventions to enhance proper sleep in athletes.

    Many common activities such as walking in a shopping mall, moving in a busy subway station, or even avoiding opponents during sports, all require different levels of navigational skills. Obstacle circumvention is beginning to be understood across age groups, but studying trained athletes with greater levels of motor ability will further our understanding of skillful adaptive locomotor behavior. The objective of this work was to compare navigational skills during fast walking between elite athletes (e.g. soccer, field hockey, basketball) and aged-matched non-athletes under different levels of environmental complexity in relation to obstacle configuration and visibility. The movements of eight women athletes and eight women non-athletes were measured as they walked as fast as possible through different obstacle courses in both normal and low lighting conditions. Results showed that athletes, despite similar unobstructed maximal speeds to non-athletes, had faster walking times during the navigation of all obstructed environments. It appears that athletes can process visuo-spatial information faster since both groups can make appropriate navigational decisions, but athletes can navigate through complex, novel, environments at greater speeds. Athletes' walking times were also more affected by the low lighting conditions suggesting that they normally scan the obstructed course farther ahead. This study also uses new objective measures to assess functional locomotor capacity in order to discriminate individuals according to their level of navigational ability. The evaluation paradigm and outcome measures developed may be applicable to the evaluation of skill level in athletic training and selection, as well as in gait rehabilitation following impairment.

  12. Osteitis pubis in elite athletes: Diagnostic and therapeutic approach

    PubMed Central

    Angoules, Antonios G

    2015-01-01

    Osteitis pubis (OP) is a debilitating overuse syndrome characterizing by pelvic pain and local tenderness over the pubic symphysis commonly encountered in athletes often involved in kicking, twisting and cutting activities in sports such as soccer and rugby and to a lesser degree distance running. It is a common source of groin pain in elite athletes attributable to pubis sympysis instability as the result of microtrauma caused by repetitive muscle strains on pubic bones. Diagnosis is based mainly on detailed sports history and a meticulous clinical examination, although occasionally is difficult to distinguish this nosological entity from other pathologies affecting the involved area which may occur concomitantly in the same patient. Radiologic examinations such as plain radiographs, magnetic resonance imaging and 3 phase bone isotope scanning may be helpful to differentiate from other clinical entities with similar clinical presentation. Most cases respond well to conservative treatment which includes several physical modalities and especially a progressive rehabilitation programmed individualized to each one of patients diagnosed with OP. Local injection therapies have been also been proposed as a non-operative therapeutic option for the efficient management of these patients. In refractory cases, surgical therapeutic strategies are warranted. These include several open or minimally invasive surgical interventions such as arthroscopic or open symphysis curettage, wedge or total resection of pubic sympysis, polypropylene mesh placement and pubic fusion. In this review a critical analysis of OP in elite athletes is performed with special focus on current concepts of diagnosis and management of this source of athletic groin pain. PMID:26495244

  14. Different Paths to Different Strategies? Unique Associations Among Facets of the Dark Triad, Empathy, and Trait Emotional Intelligence.

    2017-01-01

    Emotional deficits, such as limited empathy, are considered a fundamental aspect of the Dark Triad traits (narcissism, Machiavellianism, and psychopathy). However, the nature and extent of such deficiencies seem to vary among dark personalities. By applying multidimensional measures of empathy, emotional intelligence, and the Dark Triad, we aimed to investigate in more detail how individuals high in various dark traits understand and evaluate emotions. Results indicated that each trait, and, moreover, each facet thereof entailed unique emotional deficiencies. Narcissism was positively associated with trait emotional intelligence, whereas the secondary factor of psychopathy was associated negatively. With respect to empathy, only primary psychopathy was linked to an overall deficit, while a positive relationship was found between Machiavellianism and the perspective-taking facet of cognitive empathy. We argue that the specific emotional limitations of the Dark Triad traits might contribute to the successful deployment of different socially aversive strategies.

    [Purpose] The purpose of this study was to compare the foot and ankle condition between elite athletes and non-athletes. [Subjects] The elite athletes group included 85 subjects (28 males and 57 females) and the non-athletes group included 85 subjects (38 males and 47 females). [Methods] All subjects were evaluated for pain (visual analogue scale, VAS) and foot and ankle condition (The Foot and Ankle Disability Index, FADI, and The Foot and Ankle Outcome Score, FAOS). [Results] The elite athlete group showed significant differences from the non-athletes group in VAS, FADI (FADI, FADI-Sports), and FAOS (FAOS-symptoms, FAOS-pain, FAOS-ADL, FAOS-sports, FAOS-QoL). In addition, a meaningful difference in VAS, FADI-Sports, and FAOS-symptoms was observed between gymnasts and wrestlers. [Conclusion] The results of this study suggest the necessity prevention of injury to the foot and ankle of elite athletes, and for the development of exercise for the rehabilitation of foot and ankle injuries, because there is a difference in foot and ankle condition between elite athletes and non-athletes.

[Methods] All subjects were evaluated for pain (visual analogue scale, VAS) and foot and ankle condition (The Foot and Ankle Disability Index, FADI, and The Foot and Ankle Outcome Score, FAOS). [Results] The elite athlete group showed significant differences from the non-athletes group in VAS, FADI (FADI, FADI-Sports), and FAOS (FAOS-symptoms, FAOS-pain, FAOS-ADL, FAOS-sports, FAOS-QoL). In addition, a meaningful difference in VAS, FADI-Sports, and FAOS-symptoms was observed between gymnasts and wrestlers. [Conclusion] The results of this study suggest the necessity prevention of injury to the foot and ankle of elite athletes, and for the development of exercise for the rehabilitation of foot and ankle injuries, because there is a difference in foot and ankle condition between elite athletes and non-athletes.

    Crouzon Syndrome is an autosomal dominant disorder with complete penetrance and variable expressivity. Described by a French neurosurgeon in 1912, it is a rare genetic disorder. Crouzon syndrome is caused by mutation in the fibroblast growth factor receptor 2 (FGFR2) gene. The disease is characterized by premature synostosis of coronal and sagittal sutures which begins in the first year of life. Once the sutures become closed, growth potential to those sutures is restricted. However, multiple sutural synostoses frequently extend to premature fusion of skull base causing midfacial hypoplasia, shallow orbit, maxillary hypoplasia and occasional upper airway obstruction.The case of a 7-year-old South African black boy with Crouzon Syndrome is presented. He presented with characteristic triad of cranial deformity, maxillary hypoplasia and exophthalmos. The clinical, cephalometric features and initial orthodontic management of this patient are discussed as part of multidisciplinary management.

  19. The career planning, athletic identity, and student role identity of intercollegiate student athletes.

    The purpose of this study was to examine the career planning of university student athletes and relationships between their career planning and athletic and student role identities. Two retrospective in-depth interviews were held with four male and four female university student athletes. Participants entered university with vague or nonexistent career objectives and invested heavily in their athletic roles. In the latter years of their college career, the participants discarded their sport career ambitions and allowed the student role to become more prominent in their identity hierarchies. The current findings support Brown and Hartley's (1998) suggestion that student athletes may invest in both the athlete and student role identities simultaneously and that investing in the latter may permit the exploration of nonsport career options.

    Based on their own findings and the data available in the literature on pregnancy including that complicated by gestosis, the authors consider these conditions in the context of Selye's general adaptation syndrome. They identify its basic links (the autonomic nervous and cardiovascular systems) the function of which is affected by all the physiological and pathophysiological processes involved in its development. There is a high likelihood of baseline impaired adaption processes in these links, which may lead to an inability to accommodate (dysadaptation) by the moment of delivery. The paper gives the current interpretation of functional disorders, called Zangemeister'a triad in 1913, from the present-day points of view of the evaluation of pregnancy as the systemic inflammatory response syndrome and, probably, adaptation disease. Based on the results of analyzing the data available in the literature, the authors indicate physiologically the basic trends in the modulation of impaired development processes of the general adaptation syndrome towards the completion of pregnancy and surgical delivery.

    The current study had three aims: (1) to validate a Korean version of the Student Athletes' Motivation toward Sports and Academics Questionnaire (SAMSAQ-Kr), (2) to examine South Korean university student-athletes' motivation towards athletic and academic achievement, and (3) to identify the relationship between athletic identity and their athletic and academic achievement. A total of 126 South Korean university student-athletes (41.4% males and 58.6% females; mean age 20.5, SD = 2.74) completed the SAMSAQ-Kr. To investigate the validity evidence of the SAMSAQ-Kr a confirmatory factor analysis (CFA) and Rasch model were employed. To examine the relationship between Athletic Identity Measurement Scale (AIMS) and SAMSAQ for Spearman correlation coefficients were calculated. Findings indicated that the SAMSAQ-Kr showed a different model from other versions and revealed positive correlations between AIMS scores and athletic motivations. The current study highlighted that importance of considering socio-cultural context in developing questionnaire and contributed to help understand South Korean university student-athletes' motivation towards athletic and academic achievement.

    Objective: To present recommendations for the prevention, detection, and comprehensive management of disordered eating (DE) in athletes. Background: Athletes with DE rarely self-report their symptoms. They tend to deny the condition and are often resistant to referral and treatment. Thus, screenings and interventions must be handled skillfully by knowledgeable professionals to obtain desired outcomes. Certified athletic trainers have the capacity and responsibility to play active roles as integral members of the health care team. Their frequent daily interactions with athletes help to facilitate the level of medical surveillance necessary for early detection, timely referrals, treatment follow-through, and compliance. Recommendations: These recommendations are intended to provide certified athletic trainers and others participating in the health maintenance and performance enhancement of athletes with specific knowledge and problem-solving skills to better prevent, detect, and manage DE. The individual biological, psychological, sociocultural, and familial factors for each athlete with DE result in widely different responses to intervention strategies, challenging the best that athletics programs have to offer in terms of resources and expertise. The complexity, time intensiveness, and expense of managing DE necessitate an interdisciplinary approach representing medicine, nutrition, mental health, athletic training, and athletics administration in order to facilitate early detection and treatment, make it easier for symptomatic athletes to ask for help, enhance the potential for full recovery, and satisfy medicolegal requirements. Of equal importance is establishing educational initiatives for preventing DE. PMID:18335017

    2014-01-01

    Context: Alcohol-related unintentional injury (ARUI) has been an unexamined consequence of alcohol consumption by collegiate athletes. It has a potentially devastating effect on their athletic performances and careers. Awareness of this problem in athletes could have a huge effect on what athletic trainers (ATs) do to recognize, treat, and prevent it in a collegiate athlete population. Objective: To examine the experiences and attitudes among collegiate and university ATs about ARUI in the athletes in their care. Design: Cross-sectional study. Setting: Web-based survey. Patients or Other Participants: A total of 1767 e-mail addresses for collegiate and university ATs within National Athletic Trainers' Association Districts 1, 2, 3, and 9. Main Outcome Measure(s): We calculated frequencies, percentages, and attitudes of ATs regarding ARUI in collegiate athletes during the 2010–2011 academic year. Results: The resulting sample size for the analysis was 459 (26.0%) participants of the initial total sample. More than 56% (n = 260) of the ATs reported that they had evaluated, treated, or referred if needed at least 1 ARUI in a collegiate athlete. On average, these ATs had evaluated, treated, or referred if needed 3 alcohol-related unintentional injuries within the 2010–2011academic year. About 73% (n = 331) of ATs agreed that ARUI is a serious problem. Nearly 80% (n = 358) indicated they believe ATs should receive more training to identify student–athletes with alcohol-related problems. Conclusions: Alcohol-related unintentional injury is a common and serious consequence of alcohol use among collegiate athletes. Many ATs also view it as a serious problem yet would like more training in how to address it. Alcohol-related unintentional injury may have important negative effects on the careers and athletic performances of athletes. Researchers need to determine how prevalent ARUI is in the collegiate athlete population and what ATs can do to address it. PMID:24377956

    McCune-Albright syndrome (MAS) is characterized by a triad of poly/monoostotic fibrous dysplasia, café-au-lait macules and hyperfunctioning endocrinopathies. Association of MAS with GH excess is rare, and in most of the instances somatotropinoma has not been documented. Treatment of patients of MAS with acromegaly is difficult because of thickened calvarium and dysplastic skull bone. We report a 17-year-old girl, who presented with cranio-facial fibrous dysplasia, café-au-lait macules and also had acromegaly due to pituitary macroadenoma, and treated with gamma knife radiosurgery.

    Hill, Andrew P; Hall, Howard K; Appleton, Paul R

    2010-07-01

    Recent research indicates that some dimensions of perfectionism are positively related to athlete burnout, whereas others are negatively related to athlete burnout. The divergent relationship between these dimensions of perfectionism and athlete burnout may be explained by different coping tendencies. The present investigation examined whether different coping tendencies mediate the relationship between self-oriented and socially prescribed perfectionism and burnout. Two-hundred and six junior elite athletes (M age=15.15 years, SD=1.88 years, range=11-22 years) completed measures of self-oriented and socially prescribed perfectionism, coping tendencies, and athlete burnout. Structural equation modeling indicated that the relationship between dimensions of perfectionism and athlete burnout was mediated by different coping tendencies. Higher levels of socially prescribed perfectionism was related to higher levels of avoidant coping which, in turn, was related to higher levels of athlete burnout. In contrast, higher levels of self-oriented perfectionism was related to higher levels of problem-focused coping and lower levels of avoidant coping which, in turn, was related to lower levels of athlete burnout. The findings suggest that different coping tendencies may underpin the divergent relationship between self-oriented and socially prescribed dimensions of perfectionism and athlete burnout.

    To present recommendations for the certified athletic trainer in the management of type 1 diabetes in the athlete. In managing diabetes, the most important goal is to keep blood glucose levels at or as close to normal levels as possible without causing hypoglycemia. This goal requires the maintenance of a delicate balance among hypoglycemia, euglycemia, and hyperglycemia, which is often more challenging in the athlete due to the demands of physical activity and competition. However, effectively managing blood glucose, lipid, and blood pressure levels is necessary to ensuring the long-term health and well-being of the athlete with diabetes. These recommendations are intended to provide the certified athletic trainer participating in the management of an athlete with type 1 diabetes mellitus with the specific knowledge and problem-solving skills needed. Athletic trainers have more contact with the athlete with diabetes than most members of the diabetes management team do and so must be prepared to assist the athlete as required.

    Three cases of athlete's nodule on the feet are reported. In case 1, a 30-year-old man, who had been an amateur football player, presented with nodules on the lateral side of the feet and on the right lateral malleolus with a duration of 1 year. In case 2, a 22-year-old man, who had participated in karate and track-and-field, presented with nodules on the lateral side of the feet and on the right lateral malleolus with a duration of 10 years. In case 3, a 25-year-old man, who had skied, presented with a nodule on the right lateral malleolus with a duration of 4 years. The biopsy specimens from the lesion demonstrated hyperkeratosis, acanthosis of the epidermis and thickness of the dermis. In 1991, Cohen et al. proposed the concept of athlete's nodule which indicated an acquired cutaneous nodule caused by chronic stimuli with sports. Histopathology of the athlete's nodule shows hypertrophy of the epidermis and dermis. To the best of our knowledge the term "athlete's nodule" has not been used in Japan, but it is a useful term to refer to the lesion induced by athletics or the use of sporting equipment.

    2017-01-16

    BACKGROUND Miller Fisher Syndrome is characterized by the clinical triad of ophthalmoplegia, ataxia, and areflexia, and is considered to be a variant of Guillain-Barre Syndrome. Miller Fisher Syndrome is observed in approximately 1-5% of all Guillain-Barre cases in Western countries. Patients with Miller Fisher Syndrome usually have good recovery without residual deficits. Venous thromboembolism is a common complication of Guillain-Barre Syndrome and has also been reported in Miller Fisher Syndrome, but it has generally been reported in the presence of at least one prothrombotic risk factor such as immobility. A direct correlation between venous thromboembolism and Miller Fisher Syndrome or Guillain-Barre Syndrome has not been previously described. CASE REPORT We report the case of a 32-year-old Hispanic male who presented with acute, severe thromboembolic disease and concurrently demonstrated characteristic clinical features of Miller Fisher Syndrome including ophthalmoplegia, ataxia, and areflexia. Past medical and family history were negative for thromboembolic disease, and subsequent hypercoagulability workup was unremarkable. During the course of hospitalization, the patient also developed angioedema. CONCLUSIONS We describe a possible association between Miller Fisher Syndrome, thromboembolic disease, and angioedema.

    During the stages of long-term athlete development (LTAD), resistance training (RT) is an important means for (i) stimulating athletic development, (ii) tolerating the demands of long-term training and competition, and (iii) inducing long-term health promoting effects that are robust over time and track into adulthood. However, there is a gap in the literature with regards to optimal RT methods during LTAD and how RT is linked to biological age. Thus, the aims of this scoping review were (i) to describe and discuss the effects of RT on muscular fitness and athletic performance in youth athletes, (ii) to introduce a conceptual model on how to appropriately implement different types of RT within LTAD stages, and (iii) to identify research gaps from the existing literature by deducing implications for future research. In general, RT produced small-to-moderate effects on muscular fitness and athletic performance in youth athletes with muscular strength showing the largest improvement. Free weight, complex, and plyometric training appear to be well-suited to improve muscular fitness and athletic performance. In addition, balance training appears to be an important preparatory (facilitating) training program during all stages of LTAD but particularly during the early stages. As youth athletes become more mature, specificity, and intensity of RT methods increase. This scoping review identified research gaps that are summarized in the following and that should be addressed in future studies: (i) to elucidate the influence of gender and biological age on the adaptive potential following RT in youth athletes (especially in females), (ii) to describe RT protocols in more detail (i.e., always report stress and strain-based parameters), and (iii) to examine neuromuscular and tendomuscular adaptations following RT in youth athletes.

    Williams-Beuren syndrome is a rare neurodevelopmental disorder caused by deletion of 1.5-1.8Mb genes on chromosome 7q11.23. The syndrome was first described as a triad of supra-valvular aortic stenosis, mental retardation, and distinctive facial features. Our patient was referred due to audible inspiratory stridor when he was seven days old. Following endoscopy he was diagnosed with bilateral vocal cord paralysis and was eventually intubated due to respiratory de-compensation followed by tracheotomy. On further workup he was diagnosed with hypothyroidism. Genetic workup supported the diagnosis of Williams-Beuren syndrome. We report here a case with an unusual clinical presentation.

    Patient: Female, 6 Final Diagnosis: Allgrove syndrome Symptoms: Achalasia • adrenal insufficiency • alacrima Medication: — Clinical Procedure: — Specialty: Pediatrics and Neonatology Objective: Rare disease Background: Allgrove syndrome, or triple “A” syndrome (3A syndrome), is a rare autosomal recessive syndrome with variable phenotype, and an estimated prevalence of 1 per 1,000,000 individuals. Patients usually display the triad of achalasia, alacrima, and adrenocorticotropin (ACTH) insensitive adrenal insufficiency, though the presentation is inconsistent. Case Report: Here, the authors report a case of Allgrove syndrome in a pediatric patient with delayed diagnosis in order to raise awareness of this potentially fatal disease as a differential diagnosis of alacrima. Conclusions: The prevalence of Allgrove syndrome may be much higher as a result of underdiagnosis and missed diagnosis due to the variable presentation and sudden unexplained childhood death from adrenal crisis. The authors review the characteristic symptoms of Allgrove syndrome in relation to the case study in order to avoid missed or delayed diagnosis, potentially decreasing morbidity, and mortality in those affected by this disease.

The Five-Factor Personality Inventory (short version) and the Quality of Relationships Inventory were administered to all participants. Stepwise multiple regression analysis assessed which of the five personality factors predicted scores for the different subscales of the Quality of Relationships Inventory (Depth, Support, and Conflict). Results indicated that depth of relationship was not predicted by personality factors. On the other hand, neuroticism and extraversion were significant predictors of support dimension of relationship. Analysis indicated that conscientiousness was the strongest predictor of conflict. In conclusion, athletes' personality characteristics may be important in determining the quality of the coach-athlete relationship.

    Olive oil is the primary source of fat in the Mediterranean diet, which is associated with a significant improvement in health status, as measured by reduced mortality from several chronic diseases. The current pandemic of obesity, metabolic syndrome, and type 2 diabetes is intimately associated with an atherogenic dyslipidemic phenotype. The core components of the dyslipidemia of the metabolic syndrome, which most likely initiate atherosclerosis, are the "lipid triad" consisting of high plasma triglycerides, low levels of high-density lipoproteins, and a preponderance of small, dense low-density lipoproteins at fasting. However, postprandial (non-fasting) TGs (postprandial hyperlipidemia) are also recognized as an important component for atherosclerosis. Herein, the purpose of this review was to provide an update on the effects and mechanisms related to olive oil on postprandial hyperlipidemia and its implications for the onset and progression of atherosclerosis and metabolic syndrome.

    In general, painful feet can affect the performance of an athlete in any sport. To prevent skin diseases of the feet, the "Athlete's Foot" should be kept clean and dry with toenails trimmed. Properly fitting athletic shoes should be worn to avoid the formation of blisters. Wearing of sandals in locker and shower rooms, which prevents intimate contact with infecting organisms, can alleviate many of the problems that affect the feet.

    2018-07-01

    This study explores the importance of organizational structures and formal affiliations with the Hong Kong triads to delinquency among youth street gang members in Hong Kong. More specifically, this study examines the relative importance of the number of organizational structures and triad affiliation to patterns of delinquency in a sample of active members of youth street gangs ( N = 201). With the aid of outreach social workers, a convenience sampling method was used to recruit a gender-balanced sample of at-risk youths. Logistic regression analysis of the survey data that was gathered indicated that formal affiliation to Hong Kong triads and the presence of organizational structures significantly increased the odds of delinquency (independently of each other). Suggestions for future research on gang membership and delinquency, with particular reference to the Asian context, are provided.

    2015-01-01

    The National Collegiate Athletic Association (NCAA) has recently highlighted mental health concerns in student athletes, though the incidence of suicide among NCAA athletes is unclear. The purpose of this study was to determine the rate of suicide among NCAA athletes. The incidence of suicide in NCAA athletes differs by sex, race, sport, and division. Retrospective cohort study. Level 3. NCAA Memorial Resolutions list and published NCAA demographic data were used to identify student-athlete deaths and total participant seasons from 2003-2004 through 2011-2012. Deaths were analyzed by age, sex, race, division, and sport. Over the 9-year study period, 35 cases of suicide were identified from a review of 477 student-athlete deaths during 3,773,309 individual participant seasons. The overall suicide rate was 0.93/100,000 per year. Suicide represented 7.3% (35/477) of all-cause mortality among NCAA student athletes. The annual incidence of suicide in male athletes was 1.35/100,000 and in female athletes was 0.37/100,000 (relative risk [RR], 3.7; P < 0.01). The incidence in African American athletes was 1.22/100,000 and in white athletes was 0.87/100,000 (RR, 1.4; P = 0.45). The highest rate of suicide occurred in men's football (2.25/100,000), and football athletes had a relative risk of 2.2 (P = 0.03) of committing suicide compared with other male, nonfootball athletes. The suicide rate in NCAA athletes appears to be lower than that of the general and collegiate population of similar age.

    2017-01-01

    Ankle impingement syndromes encompass a broad spectrum of post-traumatic and chronic degenerative changes that present with pain on specific movements about the ankle joint. Both amateur and professional athletes are disproportionately affected by these conditions, and while conservative measures can potentially treat an impingement syndrome, definitive therapy is often alleviated surgically. Imaging (including conventional radiography, ultrasound, CT and MRI) plays an invaluable role in the diagnosis and pre-surgical work-up. An anatomically based classification system is useful in these syndromes, as the aetiology, sites of pathology and preferred treatment methods are similarly based on anatomic locations about the ankle. This review focuses on the anatomic locations, pathophysiology, imaging considerations and brief discussion of therapies for each of the major anatomic ankle impingement syndromes. PMID:27885856

  9. Observations of Traveling Crossflow Resonant Triad Interactions on a Swept Wing

    NASA Technical Reports Server (NTRS)

    Eppink, Jenna L.; Wlezien, Richard

    2012-01-01

    Experimental evidence indicates the presence of a triad resonance interaction between traveling crossflow modes in a swept wing flow. Results indicate that this interaction occurs when the stationary and traveling crossflow modes have similar and relatively low amplitudes (approx.1% to 6% of the total freestream velocity). The resonant interaction occurs at instability amplitudes well below those typically known to cause transition, yet transition is observed to occur just downstream of the resonance. In each case, two primary linearly unstable traveling crossflow modes are nonlinearly coupled to a higher frequency linearly stable mode at the sum of their frequencies. The higher-frequency mode is linearly stable and presumed to exist as a consequence of the interaction of the two primary modes. Autoand cross-bicoherence are used to determine the extent of phase-matching between the modes, and wavenumber matching confirms the triad resonant nature of the interaction. The bicoherence results indicate a spectral broadening mechanism and the potential path to early transition. The implications for laminar flow control in swept wing flows are significant. Even if stationary crossflow modes remain subcritical, traveling crossflow interactions can lead to early transition.

    2013-12-01

    To summarize the existing literature on the genetics of athletic performance, with particular consideration for the relevance to young athletes. Two gene variants, ACE I/D and ACTN3 R577X, have been consistently associated with endurance (ACE I/I) and power-related (ACTN3 R/R) performance, though neither can be considered predictive. The role of genetic variation in injury risk and outcomes is more sparsely studied, but genetic testing for injury susceptibility could be beneficial in protecting young athletes from serious injury. Little information on the association of genetic variation with athletic performance in young athletes is available; however, genetic testing is becoming more popular as a means of talent identification. Despite this increase in the use of such testing, evidence is lacking for the usefulness of genetic testing over traditional talent selection techniques in predicting athletic ability, and careful consideration should be given to the ethical issues surrounding such testing in children. A favorable genetic profile, when combined with an optimal training environment, is important for elite athletic performance; however, few genes are consistently associated with elite athletic performance, and none are linked strongly enough to warrant their use in predicting athletic success.

  12. Differential diagnosis and management of Behçet syndrome.

    PubMed

    Ambrose, Nicola L; Haskard, Dorian O

    2013-02-01

    Behçet syndrome (also known as Behçet disease) is a rare condition that is associated with considerable morbidity. Cases of Behçet syndrome have been reported worldwide, but the highest prevalence occurs in countries that border the ancient Silk Route, such as Turkey and Iran. Although oral ulceration, genital ulceration and eye disease are the classic triad of manifestations, the cardiovascular, gastrointestinal, musculoskeletal and central nervous systems can also be affected. The syndrome is chronic and relapsing with some patients having benign episodes whereas others have more serious complications, including blindness or the rupture of a pulmonary arterial aneurysm. Diagnosing Behçet syndrome, particularly outside of endemic regions, often incurs a considerable delay owing to the rarity of this condition. Furthermore, a paucity exists of data from randomized controlled trials on the optimal therapeutic approaches to use in patients, as well as a lack of informative laboratory surrogate markers to monitor disease progression. This Review discusses the issues surrounding the diagnosis and differential diagnosis of Behçet syndrome and presents the current approaches to managing patients with this complex group of disorders.

    2017-01-01

    Patient: Male, 58 Final Diagnosis: Bacterial meningitis Symptoms: Altered mental status • headache • neck stiffness • vomiting Medication: — Clinical Procedure: — Specialty: Infectious Diseases Objective: Rare disease Background: Gradenigo’s syndrome includes the triad of suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve. Gradenigo’s syndrome is rare, and the diagnosis is easily overlooked. This case is the first to report Gradenigo’s syndrome presenting with meningitis on a background of chronic suppurative otitis media (CSOM) and petrous apicitis (apical petrositis). Case Report: A 58-year-old male African American presented with headaches and confusion. Magnetic resonance imaging (MRI) of the head showed petrous apicitis with mastoiditis and abscess formation in the cerebellomedullary cistern (cisterna magna). The case was complicated by the development of palsy of the fourth (trochlear) cranial nerve, fifth (trigeminal) cranial nerve, and sixth (abducens) cranial nerve, with radiological changes indicating infection involving the seventh (facial) cranial nerve, and eighth (vestibulocochlear) cranial nerve. Cerebrospinal fluid (CSF) culture results were positive for Klebsiella pneumoniae, sensitive to ceftriaxone. The patient improved with surgery that included a left mastoidectomy and debridement of the petrous apex, followed by a ten-week course of antibiotics. Follow-up MRI showed resolution of the infection. Conclusions: This report is of an atypical case of Gradenigo’s syndrome. It is important to recognize that the classical triad of Gradenigo’s syndrome, suppurative otitis media, ipsilateral sixth (abducens) cranial nerve palsy and facial pain in the distribution of the fifth (trigeminal) cranial nerve, may also involve chronic suppurative otitis media (CSOM), which may lead to involvement of other cranial nerves, petrous apicitis

    McCune-Albright syndrome is a rare fibro-osseous syndrome characterised by a classic triad of fibrous dysplasia (FD), café-au-lait macules and various underlying endocrinopathies. This case report describes how a patient was rediagnosed by a general dental practitioner following attendance for a routine dental examination. The patient had been previously diagnosed with the condition 28 years earlier but no follow-up or monitoring of her condition had taken place. As a result, she was found to have several undiagnosed and untreated complications of the disease including FD of the mandible, optic neuropathy and potential thyroid involvement. PMID:25721837

    2015-09-01

    The aim of the research was to determine construct validity and reliability for two questionnaires (Athlete Engagement Questionnaire-AEQ and Athletic Identity Measurement Scale-AIMS), applied on elite Croatian athletes-sprinters, as well as the correlations among the dimensions in these measuring instruments. Then, we have determined the differences in the dimensions of sport engagement and sport identity, according to gender, education level and winning medals on international competitions. A total of 71 elite athletes-sprinters (former and still active) are examined, from which 27 (38%) females and 44 (62%) males. The results of factor analyses revealed the existence of dimensions very similar as in the original instruments, which showed moderate to-high reliabilities. A small number of statistically significant correlations have been found between the dimensions of sport engagement and sport identity, mainly in male sprinter runners. Small number of statistically significant differences in the dimensions of sport engagement and sport identity have been found according to the gender, education level and winning medals on the international competitions. The most reasonable explanation of these differences could be given in terms of very similar characteristics of elite athletes on the same level of sport excellence.

  18. A Social Capital Perspective on the Mentoring of Undergraduate Life Science Researchers: An Empirical Study of Undergraduate-Postgraduate-Faculty Triads.

    2016-01-01

    Undergraduate researchers at research universities are often mentored by graduate students or postdoctoral researchers (referred to collectively as "postgraduates") and faculty, creating a mentoring triad structure. Triads differ based on whether the undergraduate, postgraduate, and faculty member interact with one another about the undergraduate's research. Using a social capital theory framework, we hypothesized that different triad structures provide undergraduates with varying resources (e.g., information, advice, psychosocial support) from the postgraduates and/or faculty, which would affect the undergraduates' research outcomes. To test this, we collected data from a national sample of undergraduate life science researchers about their mentoring triad structure and a range of outcomes associated with research experiences, such as perceived gains in their abilities to think and work like scientists, science identity, and intentions to enroll in a PhD program. Undergraduates mentored by postgraduates alone reported positive outcomes, indicating that postgraduates can be effective mentors. However, undergraduates who interacted directly with faculty realized greater outcomes, suggesting that faculty interaction is important for undergraduates to realize the full benefits of research. The "closed triad," in which undergraduates, postgraduates, and faculty all interact directly, appeared to be uniquely beneficial; these undergraduates reported the highest gains in thinking and working like a scientist. © 2016 M.

  19. The specificity triad: notions of disease and therapeutic specificity in biomedical reasoning

    PubMed Central

    2014-01-01

    Biomedicine is typically defined as the branch of medicine that is based on the principles of biology and biochemistry. A central tenet for biomedicine is the notion of disease and therapeutic specificity, i.e. the idea of tailored treatments for discrete disorders underpinned by specific pathologies. The present paper is concerned with how notions of disease and therapeutic specificity guide biomedical reasoning. To that end, the author proposes a model – the specificity triad – that draws on late philosopher and physician Ludwik Fleck’s concept of “style of thought” to offer a frame for investigating the intricate process through which links between disorders, mechanisms, and therapeutics are established by biomedicine. Next by applying the specificity triad model to scrutinize research efforts in two discrete areas of medicine—psychiatry and regenerative medicine—this paper seeks to stimulate pertinent discussions in and about biomedicine. These include discussions on the ambiguous epistemic status of psychiatry within contemporary biomedicine, as well as the relationship between developmental biology — historically relatively disjointed from biomedical enterprise — and the burgeoning field of regenerative medicine.

    McCune-Albright syndrome (MAS) is a rare disorder characterized by the classic triad of precocious puberty, polyostotic fibrous dysplasia and café-au-lait spots. Additional endocrine abnormalities may also be present, including hyperthyroidism, growth hormone excess and hyperprolactinemia. The most commonly encountered endocrine dysfunction is gonadal hyperfunction. Gonadotropin-independent precocious puberty is typically the initial manifestation of MAS in girls. Ovarian cysts may be detected on pelvic ultrasound. Our patient was also found to have pituitary microadenoma, evidenced by dynamic magnetic resonance imaging.

    Torres-McGehee, Toni M.; Pritchett, Kelly L.; Zippel, Deborah; Minton, Dawn M.; Cellamare, Adam; Sibilia, Mike

    2012-01-01

    Context: Coaches, athletic trainers (ATs), strength and conditioning specialists (SCSs), and registered dietitians are common nutrition resources for athletes, but coaches, ATs, and SCSs might offer only limited nutrition information. Little research exists about sports nutrition knowledge and current available resources for nutrition information for athletes, coaches, ATs, and SCSs. Objective: To identify resources of nutrition information that athletes, coaches, ATs, and SCSs use; to examine nutrition knowledge among athletes, coaches, ATs, and SCSs; and to determine confidence levels in the correctness of nutrition knowledge questions within all groups. Design: Cross-sectional study. Setting: National Collegiate Athletic Association Division I, II, and III institutions across the United States. Patients and Other Participants: The 579 participants consisted of athletes (n = 185), coaches (n = 131), ATs (n = 192), and SCSs (n = 71). Main Outcome Measure(s): Participants answered questions about nutrition resources and domains regarding basic nutrition, supplements and performance, weight management, and hydration. Adequate sports nutrition knowledge was defined as an overall score of 75% in all domains (highest achievable score was 100%). Results: Participants averaged 68.5% in all domains. The ATs (77.8%) and SCSs (81.6%) had the highest average scores. Adequate knowledge was found in 35.9% of coaches, 71.4% of ATs, 83.1% of SCSs, and only 9% of athletes. The most used nutrition resources for coaches, ATs, and SCSs were registered dietitians. Conclusions: Overall, we demonstrated that ATs and SCSs have adequate sports nutrition knowledge, whereas most coaches and athletes have inadequate knowledge. Athletes have frequent contact with ATs and SCSs; therefore, proper nutrition education among these staff members is critical. We suggest that proper nutrition programming should be provided for athletes, coaches, ATs, and SCSs. However, a separate nutrition program

    2013-09-01

    Research prior to 2001 indicated that athletes experienced better body image than non-athletes, with no differences among sport types. Since then, female athletes have become increasingly sexually objectified in the media, and the sociocultural beauty ideal has shifted to emphasize appearing both athletic and thin. Part I of this paper explores the literature describing these changes. Part II presents a systematic and comprehensive literature review of 10 recent studies comparing body image concerns (BIC) among collegiate female athletes and non-athletes to identify the current status of BIC in female athletes. Findings indicate that involvement in collegiate athletics provides some protection from BIC; however, this protection appears attenuated for athletes in more feminine sports (e.g., gymnastics), and higher level athletes (Division I). Researchers should examine how sociocultural pressures unrelated to competition predict female athletes' BIC using measures that focus on objectification, positive body image, body functionality, and thin- and athletic-ideal internalization.

    α-Amylases are glycoside hydrolase enzymes that act on the α(1→4) glycosidic linkages in glycogen, starch, and related α-glucans, and are ubiquitously present in Nature. Most α-amylases have been classified in glycoside hydrolase family 13 with a typical (β/α)8-barrel containing two aspartic acid and one glutamic acid residue that play an essential role in catalysis. An atypical α-amylase (BmaN1) with only two of the three invariant catalytic residues present was isolated from Bacillus megaterium strain NL3, a bacterial isolate from a sea anemone of Kakaban landlocked marine lake, Derawan Island, Indonesia. In BmaN1 the third residue, the aspartic acid that acts as the transition state stabilizer, was replaced by a histidine. Three-dimensional structure modeling of the BmaN1 amino acid sequence confirmed the aberrant catalytic triad. Glucose and maltose were found as products of the action of the novel α-amylase on soluble starch, demonstrating that it is active in spite of the peculiar catalytic triad. This novel BmaN1 α-amylase is part of a group of α-amylases that all have this atypical catalytic triad, consisting of aspartic acid, glutamic acid and histidine. Phylogenetic analysis showed that this group of α-amylases comprises a new subfamily of the glycoside hydrolase family 13. PMID:28287181

  8. Internal wave mode resonant triads in an arbitrarly stratified finite-depth ocean with background rotation

    2017-11-01

    Internal tides generated by barotropic tides on bottom topography or the spatially compact near-inertial mixed layer currents excited by surface winds can be conveniently represented in the linear regime as a superposition of vertical modes at a given frequency in an arbitrarily stratified ocean of finite depth. Considering modes (m , n) at a frequency ω in the primary wave field, we derive the weakly nonlinear solution, which contains a secondary wave at 2 ω that diverges when it forms a resonant triad with the primary waves. In nonuniform stratifications, resonant triads are shown to occur when the horizontal component of the classical RTI criterion k->1 +k->2 +k->3 = 0 is satisfied along with a non-orthogonality criterion. In nonuniform stratifications with a pycnocline, infinitely more pairs of primary wave modes (m , n) result in RTI when compared to a uniform stratification. Further, two nearby high modes at around the near-inertial frequency often form a resonant triad with a low mode at 2 ω , reminiscent of the features of PSI near the critical latitude. The theoretical framework is then adapted to investigate RTI in two different scenarios: low-mode internal tide scattering over topography, and internal wave beams incident on a pycnocline.

    2017-06-01

    The potential relationship between physical activity and endogenous pain modulatory capacity remains unclear. Therefore, the aim of the current study was to compare the pain modulatory responses of athletes and non-athletes. Conditioned pain modulation (CPM) was assessed in 15 athletes and 15 non-athletes at rest. Participation was restricted to pain-free males between 18 and 40 years of age. To measure CPM capacity, a sequential CPM testing protocol was implemented, whereby a test stimulus (pressure pain threshold [PPT]) was presented before and immediately after a conditioning stimulus (4-min cold-pressor test). Pain intensity ratings were obtained at 15-s intervals throughout the cold-pressor task using a numerical rating scale. Athletes demonstrated higher baseline PPTs compared to non-athletes (P = .03). Athletes also gave lower mean (P < .001) and maximum (P < .001) pain intensity ratings in response to the conditioning stimulus. The conditioning stimulus had a stronger inhibitory effect on the test stimulus in athletes, showing enhanced CPM in athletes compared to non-athletes (P < .05). This finding of enhanced CPM in athletes helps clarify previous mixed findings. Potential implications for exercise performance and injury are discussed.

  11. Do athletes have a right to access data in their Athlete Biological Passport?

    PubMed

    Devriendt, Thijs; Chokoshvili, Davit; Favaretto, Maddalena; Borry, Pascal

    2018-05-01

    The Athlete Biological Passport (ABP) refers to the collection of data related to an individual athlete. The ABP contains the Haematological Module and the Steroidal Module, which are used for the longitudinal monitoring of variables in blood and urine, respectively. Based on changes in these variables, a statistical model detects outliers which indicate doping use and guide further targeted testing of the athlete. Presently, athletes can access their data of the Haematological Module in the Anti-Doping Administration and Management System (ADAMS). However, granting athletes access to this data has been a matter of debate within the anti-doping community. This article investigates whether an athlete has a right to access the contents of their ABP profile. We approached this discussion by comparing the nature of ABP data with that of forensic and medical data and touched on important concerns with ABP data disclosure to athletes such as potentially allowing for the development of alternative doping techniques to circumvent detection; and making athletes vulnerable to pressure by the media to publicly release their data. Furthermore, given that ABP data may contain medically relevant information that can be used to diagnose disease, athletes may over-interpret its medical significance and wrongly see it as a free health check. We argue that safeguarding the integrity of the ABP system must be seen as the most essential element and thus a departure from immediate data disclosure is necessary. Two different strategies for delayed data disclosure are proposed which diminish the chances of ABP data being misused to refine doping techniques. Copyright © 2018 John Wiley & Sons, Ltd.

    Youth athlete specialization has been linked to decreased enjoyment, burnout, and increased injury risk, although the impact of specialization on athletic success is unknown. The extent to which parents exert extrinsic influence on this phenomenon remains unclear. The goal of this study was to assess parental influences placed on young athletes to specialize. It was hypothesized that parents generate both direct and indirect pressures on specialized athletes. Cross-sectional study; Level of evidence, 3. A survey tool was designed by an interdisciplinary medical team to evaluate parental influence on youth specialization. Surveys were administered to parents of the senior author's orthopaedic pediatric patients. Of the 211 parents approached, 201 (95.3%) completed the assessment tool. One-third of parents stated that their children played a single sport only, 53.2% had children who played multiple sports but had a favorite sport, and 13.4% had children who balanced their multiple sports equally. Overall, 115 (57.2%) parents hoped for their children to play collegiately or professionally, and 100 (49.7%) parents encouraged their children to specialize in a single sport. Parents of highly specialized and moderately specialized athletes were more likely to report directly influencing their children's specialization ( P = .038) and to expect their children to play collegiately or professionally ( P = .014). Finally, parents who hired personal trainers for their children were more likely to believe that their children held collegiate or professional aspirations ( P = .009). Parents influence youth athlete specialization both directly and by investment in elite coaching and personal instruction. Parents of more specialized athletes exert more influence than parents of unspecialized athletes.

    The design, synthesis and study of a series of carotenoid-chlorophyll-quinone triad molecules which mimic some of the basic photochemistry and photophysics of natural photosynthesis is sought. The first members of this series have now been prepared, and have been found to mimic photosynthetic charge separation, carotenoid antenna function, and carotenoid photoprotection from singlet oxygen damage. Although the triad molecules mimic the general principle of multistep electron transfer which is found in natural photosynthesis, the details of photosynthetic electron transfer differ in the triads, in that the first electron transfer step involves electron donation from the excited state donor, followed bymore » reduction of the resulting donor radical cation by the carotenoid. In photosynthesis, the electron is moved through several acceptors before the chlorophyll radical cation is reduced. Therefore, our recent work has concentrated on the design and synthesis of new model systems which better mimic certain aspects of natural photosynthesis.« less

    Recent meta-analyses of the literature confirmed the association between the RR+RX genotype of the ACTN3 R577X polymorphism and elite sprint/power athletic status in Europeans but not in Asians and Africans, while the association between the R577X genotype and elite endurance athlete status is less convincing. The aim of the present study was to investigate the association between the ACTN3 R577X genotype and elite athlete status in a large Asian (Japanese) cohort of track and field athletes. One-thousand fifty-seven Japanese track and field athletes (627 sprint/power athletes and 430 endurance athletes) and 810 Japanese controls were genotyped for the ACTN3 R577X polymorphism (rs1815739) by using the TaqMan® SNP Genotyping Assay. Elite sprint/power athletes had a higher frequency of the RR+RX genotype than the controls (OR: 1.59, 95% CI: 1.16-2.18; P = .003). A significant linear correlation was found between the RR + RX genotype and athlete status (i.e. regional < national < international) in sprint/power athletes (regional: 71%, national: 81%, international: 84%; P = .001 for trend) and long-distance runners (regional: 65%, national: 72%, international: 82%; P = .030 for trend). The data obtained for this large Asian (Japanese) cohort of track and field athletes served to confirm the association between the RR + RX genotype of the ACTN3 R577X polymorphism and elite sprint/power athlete status and also the association between the ACTN3 RR + RX genotype and long-distance running athletic status.

  15. The Controversial Second Impact Syndrome: A Review of the Literature.

    2016-09-01

    Second impact syndrome is a devastating injury that primarily affects athletic children and young adults. It occurs when a second concussion occurs before symptoms from the first concussion have resolved. Diffuse and often catastrophic cerebral edema results. Reports of second impact syndrome are few, and some argue that second impact syndrome is simply diffuse cerebral swelling unrelated to the first concussion. Ovid and PubMed were searched from years 1946 to 2015 using the terms "second impact syndrome," "repeat concussion," and "catastrophic brain injury." In addition, review articles were found using a combination of the terms, "concussion," "second impact syndrome," and "repetitive head trauma." Seventeen patients in seven publications met the criteria of having two witnessed hits and persistent symptoms from the first to the second concussion. Ten of the 17 (59%) included individuals were football players. All were male. Ages ranged from 13 to 23 years. All children with poor outcomes (death or permanent disability) were younger than 20 years, while four of the five players with good outcomes were older than 19 years. The lag time from first to second concussion ranged from one hour to four weeks, and in many cases, at least one of the two hits appeared minor. American football, male gender, and young age appear to be associated with second impact syndrome. Controversies surrounding this syndrome are discussed. There is a need for prospective studies to clarify risk factors and outcomes of second impact syndrome to guide return-to-play recommendations for young athletes. Copyright © 2016 Elsevier Inc.

    Niikawa-Kuroki syndrome (Kabuki syndrome) is a multiple congenital anomaly syndrome of unknown etiology with a very wide spectrum of abnormalities and severity. The aim of this paper was to report the first case of the syndrome in Kazakhstan associated café au lait. Five year and half old boy from Kazakhstan (Uzbek-of Turk ethnicity) presented with dysmorphic facial features (long palpebral fissures, a broad and depressed nasal tip, large prominent earlobes, small head, epicanthic folds short stature, delayed language development, hypotonia, bilateral developmental dysplasia of the hip (DDH), large ears and triangular chin, café au lait spots. The clinical diagnosis was based on the triad of characteristic facial abnormalities (long palpebral fissures, a broad and depressed nasal tip, large prominent earlobes, small head), growth retardation, (DDH). In this paper the authors report the first case of Kabuki syndrome associated with café au lait spots.

    2015-07-01

    The goal of this study was to perform a meta-analysis of the published literature to investigate the relationship of high levels of exercise training to left atrial (LA) size. The "athlete's heart" is a series of cardiac adaptations to systematic exercise training and may include LA enlargement. We conducted a systematic review of English-language studies in MEDLINE and Scopus from inception through April 29, 2014, that reported LA size in elite athletes. A total of 54 studies comprising 7,189 elite athletes and 1,375 controls were included. Forty-eight of the 54 studies reported absolute LA diameter in 7,018 athletes and 1,044 controls. Nine of the 54 studies (including 992 athletes and 426 controls) presented LA volume corrected for body surface area. The adjusted weighted mean LA diameter was 4.1 mm greater in athletes overall compared with sedentary controls (p < 0.0001), and LA volume index was 7.0 ml/m(2) greater in athletes than controls (p < 0.01). Compared with controls, LA diameter was 4.6 mm greater in endurance-trained athletes (p < 0.0001), 2.9 mm greater in strength-trained athletes (p < 0.03), 3.5 mm greater in combined strength- and endurance-trained athletes (p < 0.0001), and 4.2 mm greater in athletes with unspecified training (p < 0.02). To our knowledge, this is the largest compilation of studies documenting that elite athletes have larger LA dimensions compared with controls when evaluated by either LA diameter or LA volume corrected for body surface area. The largest average LA diameters were reported in endurance athletes. Physicians evaluating athletes should be aware that the LA is increased in both strength- and endurance-trained elite athletes.

    2014-01-01

    Context: Sports hernia/athletic pubalgia has received increasing attention as a source of disability and time lost from athletics. Studies are limited, however, lacking consistent objective criteria for making the diagnosis and assessing outcomes. Evidence Acquisition: PubMed database through January 2013 and hand searches of the reference lists of pertinent articles. Study Design: Review article. Level of Evidence: Level 5. Results: Nonsurgical outcomes have not been well reported. Various surgical approaches have return-to–athletic activity rates of >80% regardless of the approach. The variety of procedures and lack of outcomes measures in these studies make it difficult to compare one surgical approach to another. There is increasing evidence that there is an association between range of motion–limiting hip disorders (femoroacetabular impingement) and sports hernia/athletic pubalgia in a subset of athletes. This has added increased complexity to the decision-making process regarding treatment. Conclusion: An association between femoroacetabular impingement and athletic pubalgia has been recognized, with better outcomes reported when both are managed concurrently or in a staged manner.

    Intercollegiate athletes report greater alcohol consumption and more alcohol-related problems than their non-athlete peers. Although college athletes share many of the same problems faced by non-athletes, there are some consequences that are unique to athletes. Studies have demonstrated that alcohol negatively affects athletic performance including increased dehydration, impeded muscle recovery, and increased risk for injury. Beyond risk factors for alcohol misuse that may affect college students in general, research has begun to examine risk factors that are unique to collegiate athletes. For example, research has found that off-season status, the leadership role, and athlete-specific drinking motives are associated with increased alcohol use. Given these findings, it is possible that other athlete-specific variables influence alcohol misuse. One such variable may be sport achievement orientation. The purpose of the current study was to examine the relationship between sport achievement orientation and alcohol outcomes. Given previous research regarding seasonal status and gender, these variables were examined as moderators. Varsity athletes (n=263) completed the Sport Orientation Questionnaire, which assesses sport-related achievement orientation on three scales (Competitiveness, Win Orientation, and Goal Orientation). In addition, participants completed measures of alcohol use and alcohol-related problems. Results indicated that Competitiveness, Win Orientation, and Goal Orientation were all significantly associated with alcohol use, but not alcohol-related problems. Moreover, these relationships were moderated by seasonal status and gender. These interactions, clinical implications, and limitations are discussed. © 2013.

    Fat embolism syndrome (FES) is a known complication of traumatology, especially in long bone fractures. Fat embolic events are most often clinically insignificant and difficult to recognize since clinical manifestations are varied and there is no routine laboratory or radiographic diagnostic tool. Classically, FES presents with the triad of pulmonary distress, mental status changes, and petechial rash 24 to 48 hours after long-bone fracture. We report the intensive care management of a 16-year-old female patient who developed traumatic fat embolism syndrome. Traumatic fat embolism was diagnosed, based on suggestive clinical manifestations, radiographic and laboratory findings and confirmed by the demonstration of arterial hypoxemia in the absence of other disorders. Admission to the intensive care unit, mechanical ventilatory support with positive end-expiratory pressure and supportive therapy leaded to the patient's improvement and she was discharged with planned open reduction and internal fixation.

    In 1927, Arthur C. Alport first published his description of a triad of symptoms in a family with hereditary congenital haemorrhagic nephritis, deafness and ocular changes. A few years after his death, this group of symptoms was renamed Alport syndrome. To this day, Alport syndrome still inevitably leads to end-stage renal disease and the need for renal replacement therapy, starting in young adulthood. During the past two decades, research into this rare disease has focused on the effects of mutations in collagen type IV and the role of changes in podocytes and the glomerular basement membrane that lead to early kidney fibrosis. Animal models of Alport syndrome also demonstrate the pathogenetic importance of interactions between podocytes and the extracellular matrix. Such models might also help researchers to answer basic questions about podocyte function and the development of fibrosis, and to develop new therapeutic approaches that might be of use in other kidney diseases. In this Review, we discuss the latest basic and clinical research on Alport syndrome, focusing on the roles of podocyte pathology and the extracellular matrix. We also highlight early diagnosis and treatment options for young patients with this disorder.

    The incidence of homicide-related death among individuals of college age in the United States population is estimated at 15.5/100,000. The incidence of homicide among National Collegiate Athletic Association (NCAA) athletes is unknown. To investigate the rate of homicide-related death in NCAA athletes and to identify associated risk factors. The NCAA Resolutions list, NCAA catastrophic insurance claims, media reports, and published NCAA demographic data were used to identify student athlete deaths and total participant seasons from 2003-04 through 2012-13. Homicide-related deaths were analysed by sex, race, division, sport, method, location, and circumstance. Internet searches were used to gather case details. Forty-two cases of homicide-related death were identified from 4,242,519 individual participant seasons during the ten-year study period. The incidence of homicide-related death in NCAA athletes was 1.0/100,000. The incidence in males was 1.45/100,000 and in females was 0.4/100,000 (relative risk (RR) 2.9, p=0.01). The incidence in black athletes was 4.2/100,000 and in white athletes was 0.4/100,000 (RR 7.0, p<0.001). The highest sport-specific homicide-related death rate was in American football (3.7/100,000), with a RR of 4.4 (p=0.002) compared to all other sports. 88% of cases occurred off-campus. 38% of cases occurred at a social gathering, and 38% of cases occurred in a place of residence. 74% involved a fatal shooting. Homicide-related deaths in NCAA athletes occur most commonly in males, black athletes, and American football players. Understanding the incidence, risk factors, and circumstances of homicide-related deaths in college athletes may assist NCAA institutions in developing preventative measures.

    Atypical haemolytic uraemic syndrome is one of the main variants of thrombotic microangiopathy, and is characterized by excessive complement activation in the microvasculature. It is also characterised by the clinical triad; non-immune haemolytic anaemia, thrombocytopenia, and acute renal failure. In addition, 60% of patients have mutations in the genes encoding complement regulators (factor H, factor I, membrane cofactor proteins, and thrombomodulin), activators (factor B and C3), as well as autoantibodies against factor H. Multiple factors are required for the disease to manifest itself, including a trigger and gene mutations with adequate penetration. Being one of the differential diagnoses of preeclampsia- eclampsia and HELLP syndrome means that the clinician must be familiar with the disease due to its high mortality, which can be modified with early diagnosis and comprehensive treatment.

    2001-01-01

    Objective: To emphasize the importance of decreasing the response time by a trained target responder to increase the survival rate among athletes experiencing sudden cardiac arrest at an athletic event. Background: Death due to sudden cardiac arrest that is witnessed is preventable in many cases. However, most people who experience this condition die because of a prolonged response time from onset of the fatal arrhythmia to defibrillation by trained treatment providers. If athletic trainers or other members of the athletic care medical team are trained as target responders and equipped with automated electronic defibrillators, they can immediately treat an athlete who experiences a sudden, life-threatening tachyarrhythmia. This prompt response to the life-threatening emergency should result in a higher survival rate. Description: We review the causes of sudden cardiac arrest during athletic events, note some unusual clinical presentations, discuss improved methods of response and new equipment for treatment, and define the athletic trainer's role as a target responder trained to treat people experiencing sudden cardiac arrest at an athletic event. Clinical Advantages: An athletic care team willing to become part of an emergency response team can help improve the survival rate of athletes experiencing sudden cardiac arrest at an athletic event.

  8. Elite athletes and pubertal delay.

    PubMed

    Kapczuk, Karina

    2017-10-01

    Intensive physical training and participation in competitive sports during childhood and early adolescence may affect athletes' pubertal development. On the other hand, pubertal timing, early or late, may impact on an athlete selection for a particular sport. Genetic predisposition, training load, nutritional status and psychological stress determine athletes' pubertal timing. Athletes that practice esthetic sports, especially gymnasts, are predisposed to a delay in pubertal development. The growing evidence indicates that energy deficiency, not a systemic training per se, plays a crucial role in the pathogenesis of functional hypothalamic hypogonadism in female athletes. Metabolic and psychologic stress activate hypothalamic-pituitary-adrenal axis and suppress hypothalamic-pituitary-ovarian axis. Female athletes who do not begin secondary sexual development by the age of 14 or menstruation by the age of 16 warrant a comprehensive evaluation and a targeted treatment. Somatic growth and sexual maturation of elite female athletes are largely sport-specific since each sport favors a particular somatotype and requires a specific training. Chronic negative energy balance resulting from a systemic physical training and inadequate energy intake may delay pubertal development in elite athletes. Youth athletes, especially those engaged in competitive sports that emphasize prepubertal or lean appearance, are at risk of developing relative energy deficiency in sport associated with disordered eating or eating disorders. Management strategies should address the complex conditions underlying functional hypothalamic hypogonadism.

    This study quantified professional athletes' endorsement of food and beverages, evaluated the nutritional quality of endorsed products, and determined the number of television commercial exposures of athlete-endorsement commercials for children, adolescents, and adults. One hundred professional athletes were selected on the basis of Bloomberg Businessweek's 2010 Power 100 rankings, which ranks athletes according to their endorsement value and prominence in their sport. Endorsement information was gathered from the Power 100 list and the advertisement database AdScope. Endorsements were sorted into 11 endorsement categories (eg, food/beverages, sports apparel). The nutritional quality of the foods featured in athlete-endorsement advertisements was assessed by using a Nutrient Profiling Index, whereas beverages were evaluated on the basis of the percentage of calories from added sugar. Marketing data were collected from AdScope and Nielsen. Of 512 brands endorsed by 100 different athletes, sporting goods/apparel represented the largest category (28.3%), followed by food/beverages (23.8%) and consumer goods (10.9%). Professional athletes in this sample were associated with 44 different food or beverage brands during 2010. Seventy-nine percent of the 62 food products in athlete-endorsed advertisements were energy-dense and nutrient-poor, and 93.4% of the 46 advertised beverages had 100% of calories from added sugar. Peyton Manning (professional American football player) and LeBron James (professional basketball player) had the most endorsements for energy-dense, nutrient-poor products. Adolescents saw the most television commercials that featured athlete endorsements of food. Youth are exposed to professional athlete endorsements of food products that are energy-dense and nutrient-poor.

    McDowall, Jill Anne

    2007-01-01

    This paper reviews studies of supplement use among child and adolescent athletes, focusing on prevalence and type of supplement use, as well as gender comparisons. Supplement use among adult athletes has been well documented however there are a limited number of studies investigating supplement use by child and adolescent athletes. A trend in the current literature revealed that the most frequently used supplements are in the form of vitamin and minerals. While health and illness prevention are the main reasons for taking supplements, enhanced athletic performance was also reported as a strong motivating factor. Generally, females are found to use supplements more frequently and are associated with reasons of health, recovery, and replacing an inadequate diet. Males are more likely to report taking supplements for enhanced performance. Both genders equally rated increased energy as another reason for engaging in supplement use. Many dietary supplements are highly accessible to young athletes and they are particularly vulnerable to pressures from the media and the prospect of playing sport at increasingly elite levels. Future research should provide more direct evidence regarding any physiological side effects of taking supplements, as well as the exact vitamin and mineral requirements for child and adolescent athletes. Increased education for young athletes regarding supplement use, parents and coaches should to be targeted to help the athletes make the appropriate choices. Key pointsSupplement use among the child and adolescent athlete population is widespread with the most frequently used supplement being a form of vitamin/mineral supplement.The effects of supplement use on the growth and development of children and adolescents remain unclear and thus use of supplements by this population should be discouraged.It is likely that there is a misunderstanding as to the role of vitamins and minerals in the diet, their function in maintaining overall health, their role

    Accurate diagnosis of sport-related concussions relies heavily on truthful self-reporting of symptom severity. Previous studies have emphasized lack of knowledge as a factor in symptom nondisclosure. This study sought to examine concussion knowledge and the relationship of knowledge to reasons for symptom nondisclosure. Cross-sectional study. Data were collected during preparticipation athletic evaluations via electronic survey. One hundred fifty-six incoming National Collegiate Athletic Association Division I student-athletes. Survey items included previous concussion diagnosis, concussion fact and symptom knowledge, reasons and situational contexts for nondisclosure, and stakeholder attitudes. Participants, on average, had substantial concussion symptom and fact knowledge. Unexpectedly, participants with higher concussion fact knowledge endorsed more reasons that athletes may hide symptoms. Concussion symptom knowledge was unrelated to reasons for nondisclosure. Athletes believed that symptom reporting was less likely in high-stakes versus low-stakes situations and consistently identified their teammates as holding attitudes that support underreporting and athletic trainers as engaging in behaviors that support player safety. Greater concussion knowledge did not reduce the number of reasons that participants viewed as drivers for concussion nondisclosure. In other words, participants understood why athletes choose to hide symptoms even when they also understood the symptoms, risks, sequelae, and consequences of concussion (and potential harm of nondisclosure). Situational contexts and important stakeholder attitudes also appeared to importantly influence symptom disclosure decisions. A multifaceted approach that goes beyond current educational strategies to addresses situational, social, and athletic pressures may be needed to initiate a widespread cultural shift away from concussion nondisclosure.

    2013-01-01

    Objective The FTO A/T polymorphism (rs9939609) is a strong candidate to influence obesity-related traits. Elite athletes from many different sporting disciplines are characterized by low body fat. Therefore, the aim of this study was to assess whether athletic status is associated with the FTO A/T polymorphism. Subjects and Methods A large cohort of European Caucasians from Poland, Russia and Spain were tested to examine the association between FTO A/T polymorphism (rs9939609) and athletic status. A total of 551 athletes were divided by type of sport (endurance athletes, n = 266 vs. sprint/power athletes, n = 285) as well as by level of competition (elite-level vs. national-level). The control group consisted of 1,416 ethnically-matched, non-athletic participants, all Europeans. Multinomial logistic regression analyses were conducted to assess the association between FTO A/T genotypes and athletic status/competition level. Results There were no significantly greater/lesser odds of harbouring any type of genotype when comparing across athletic status (endurance athletes, sprint/power athletes or control participants). These effects were observed after controlling for sex and nationality. Furthermore, no significantly greater/lesser odds ratios were observed for any of the genotypes in respect to the level of competition (elite-level vs. national-level). Conclusion The FTO A/T polymorphism is not associated with elite athletic status in the largest group of elite athletes studied to date. Large collaborations and data sharing between researchers, as presented here, are strongly recommended to enhance the research in the field of exercise genomics. PMID:23573268

    2008-12-01

    A case series of 6 athletes with a suspected sports hernia. Groin pain in athletes is common, and 1 source of groin pain is athletic pubalgia, or a sports hernia. Description of this condition and its management is scarce in the physical therapy literature. The purpose of this case series is to describe a conservative approach to treating athletes with a likely sports hernia and to provide physical therapists with an algorithm for managing athletes with this dysfunction. Six collegiate athletes (age range, 19-22 years; 4 males, 2 females) with a physician diagnosis of groin pain secondary to possible/probable sports hernia were referred to physical therapy. A method of evaluation was constructed and a cluster of 5 key findings indicative of a sports hernia is presented. The athletes were managed according to a proposed algorithm and received physical therapy consisting of soft tissue and joint mobilization/manipulation, neuromuscular re-education, manual stretching, and therapeutic exercise. Three of the athletes received conservative intervention and were able to fully return to sport after a mean of 7.7 sessions of physical therapy. The other 3 athletes reached this outcome after surgical repair and a mean of 6.7 sessions of physical therapy. Conservative management including manual therapy appears to be a viable option in the management of athletes with a sports hernia. Follow-up randomized clinical trials should be performed to further investigate the effectiveness of conservative rehabilitation compared to a homogeneous group of patients undergoing surgical repair for this condition.

    Context: Treating both the body and the mind of an injured or ill patient is accepted as necessary for full healing to occur. However, treating the spiritual needs of the patient has less consensus. Objective: To determine the perceptions and practices of certified athletic trainers (ATs) working in the college/university setting pertaining to spiritual care of the injured athlete. Design: Cross-sectional study. Setting: A survey instrument was e-mailed to a stratified random sample of 2000 ATs at 4-year colleges and universities. Patients or Other Participants: Five hundred sixty-four participants (296 men, 234 women; 34 did not specify sex). Main Outcome Measure(s): We measured the ATs' perceptions and practices related to spiritual care for athletes. Results: We found that 82.4% of respondents agreed that addressing spiritual concerns could result in more positive therapeutic outcomes for athletes; however, 64.3% disagreed that ATs are responsible for providing the spiritual care. Positive correlations were found between personal spirituality and items favoring implementing spiritual care. Conclusions: Athletic trainers have a conceptual appreciation of the importance of spiritual care for athletes, but the practicalities of how to define, acquire skills in, and practice spiritual care are unresolved.

    Le syndrome de Currarino (SC) est défini par une triade rassemblant une malformation ano-rectale, une agénésie sacrée et une tumeur pré-sacrée. Nous rapportons le cas d'une fille de 4 ans et demi ayant été admise en consultation de gastro-entérologie pédiatrique pour constipation avec issue de selle à travers un orifice vulvaire. La radiographie du rachis avait montré une agénésie sacrée. Le fistulo-scanner a mis en évidence une fistule recto-vaginale et l'IRM pelvienne a confirmé l'agénésie sacrée et a retrouvé une méningocèle antérieure. La découverte d'une malformation ano-rectale doit faire chercher une autre anomalie de la triade de Currarino. Cette affection, rare, nécessite une prise en charge médico-chirurgicale assez complexe.

    Athletic identity (AI) has been suggested as a variable that can have an impact on the psychological health of the athletes upon retirement. The aim of this study was to provide more insight on the transition out of elite sport by assessing and comparing the extent of AI and self-esteem in an active group (AG) and a retired group (RG) of Paralympic athletes. Perceived stress and depressive symptoms were additionally assessed in the AG and RG, respectively. A non-probability sampling method was used to recruit active and retired Paralympic athletes (AG, n = 43; RG, n = 41, where 35 retired voluntarily and 6 retired involuntarily) with visual or physical impairments, from Dutch-, English-, Portuguese- and Spanish-speaking countries. Participants completed an electronic survey with questionnaires to assess the study variables mentioned above. Descriptive analysis, comparisons (Mann-Whitney U test and t-test) and Spearman's correlation coefficient were performed for the statistical analysis. Scores of AI were significantly lower in the RG (44.6 ± 9.6) compared to the AG (49.4 ± 8.9); t(82) = 2.36, p = .021, d = 0.51. No differences in self-esteem were found between RG and AG; however, within the RG, athletes who involuntarily retired (21 ± 7.1) had significantly lower self-esteem scores than those who retired voluntarily (25.2 ± 4.2); t(39) = 2.04, p = .049, d = 0.73. In conclusion, free choice upon retirement can positively influence the athletes' self-esteem, whereas a strong AI may negatively influence the retirement process, as it was positively correlated with depressive symptoms (ρ = .409, p = .008). These findings can have practical implications for sport psychologists to better support their athletes.

    BACKGROUND The hemolytic–uremic syndrome consists of the triad of microangiopathic hemolytic anemia, thrombocytopenia, and renal failure. The common form of the syndrome is triggered by infection with Shiga toxin–producing bacteria and has a favorable outcome. The less common form of the syndrome, called atypical hemolytic–uremic syndrome, accounts for about 10% of cases, and patients with this form of the syndrome have a poor prognosis. Approximately half of the patients with atypical hemolytic–uremic syndrome have mutations in genes that regulate the complement system. Genetic factors in the remaining cases are unknown. We studied the role of thrombomodulin, an endothelial glycoprotein with anticoagulant, antiinflammatory, and cytoprotective properties, in atypical hemolytic–uremic syndrome. METHODS We sequenced the entire thrombomodulin gene (THBD) in 152 patients with atypical hemolytic–uremic syndrome and in 380 controls. Using purified proteins and cell-expression systems, we investigated whether thrombomodulin regulates the complement system, and we characterized the mechanisms. We evaluated the effects of thrombomodulin missense mutations associated with atypical hemolytic–uremic syndrome on complement activation by expressing thrombomodulin variants in cultured cells. RESULTS Of 152 patients with atypical hemolytic–uremic syndrome, 7 unrelated patients had six different heterozygous missense THBD mutations. In vitro, thrombomodulin binds to C3b and factor H (CFH) and negatively regulates complement by accelerating factor I–mediated inactivation of C3b in the presence of cofactors, CFH or C4b binding protein. By promoting activation of the plasma procarboxypeptidase B, thrombomodulin also accelerates the inactivation of anaphylatoxins C3a and C5a. Cultured cells expressing thrombomodulin variants associated with atypical hemolytic–uremic syndrome had diminished capacity to inactivate C3b and to activate procarboxypeptidase B and were

    The purpose of the present study was to examine chiropractic utilization following a sport-related injury among National Team members and other high level Taekwondo athletes. Methods Retrospective surveys were conducted among Canadian male and female Taekwondo athletes (Group A, n = 60) competing in a national tournament and National Taekwondo team athletes (Group B, n = 16) at a training camp. Results A response rate of 46.7% (Group A) and 100% (Group B) was achieved. Twenty five percent (n = 4) of Group A athletes reported never seen a doctor of chiropractic (DC) regarding their injuries. Over 12% (n = 2) reported visiting a DC often, while just over 6% (n = 1) reported that they usually visited the DC following an injury. When injured, over 36% (n = 7) of the National Team members visit their family physician, over 15% (n = 3) visit a chiropractor or physiotherapist and the remaining athletes (n = 6) equally visit osteopaths, massage therapists, or athletic therapist following an injury. Conclusion There is a lack of information surrounding chiropractic utilization in the majority of sports and minimal research published regarding the health care utilization of Taekwondo athletes. Chiropractors, and particularly those with extensive athlete contact, should endeavour to further utilization studies. PMID:18516286

    Elite athletics, particularly endurance sports, are characterised by a high prevalence of bronchial hyperresponsiveness (BHR) and exercise-induced asthma (EIA). Findings in several studies suggest short-term high intensity physical activity to cause a transient increase in BHR. Recent studies in Oslo have shown that regular physical endurance training over several years, particularly when combined with such climatic factors as low air temperatures, may result in an increased risk of BHR and EIA among elite athletes--e.g., cross-country skiers. Inhalation beta 2-agonists and steroids have been used by many athletes in endurance sports, particularly skiers. Athletes with symptoms of BHR or EIA should be examined with lung function tests and exercise testing, and the effect of antiasthmatic drugs should be ascertained. Inhaled beta 2-agonists have no beneficial effect upon physical performance in nonasthmatic athletes, and may have a slight limiting effect upon physical endurance.

    Context: Low Back Pain (LBP) in athletes is common and has a broad spectrum of differential diagnoses that must be taken in to account when a clinician approaches the patient with LBP. The physicians should take into account spinal and extra spinal causes of low back pain in athletes. Evidence Acquistion: A literature review was performed for the years 1951 through 2013. Keywords used were Low Back Pain and Athletes. We searched MEDLINE, EMBASE, OVID, PUBMED, the Cochrane Library, ELSEVIER, and the references of reviewed articles, for English-language of Low Back Pain in Athletes. Results: The two most common causes of LBP arising from spine in athletes are degenerative disc disease and spondylolysis with or without listhesis. Although most athletes, respond well to conservative treatment, surgical treatment is indicated when conservative treatment failes. Conclusions: The major concern in athletes with LBP is return to play and previous level of their activity after treatment. There is insufficient evidence regarding this issue in literature to define the optimal time of return to play following treatment. PMID:26448841

    Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects the child and adolescent population. It is characterized by impairment in attention/concentration, hyperactivity, and impulsivity, all of which can impact performance of athletes. ADHD treatment within the athletic population is a unique challenge. The research in this field has been relatively limited. The National Collegiate Athletic Association and International Olympic Committee both regulate the use of psychostimulants for treatment of ADHD due to their performance-enhancing effects. In this article, authors have discussed the screening methods, pharmacological treatment, side effects, and behavioral approaches for the treatment of ADHD in adolescent athletes. PMID:24987666

    Vegetarian diets are associated with several health benefits, but whether a vegetarian or vegan diet is beneficial for athletic performance has not yet been defined. Based on the evidence in the literature that diets high in unrefined plant foods are associated with beneficial effects on overall health, lifespan, immune function, and cardiovascular health, such diets likely would promote improved athletic performance as well. In this article, we review the state of the literature on vegetarian diets and athletic performance, discuss prevention of potential micronutrient deficiencies that may occur in the vegan athlete, and provide strategies on meeting the enhanced caloric and protein needs of an athlete with a plant-based diet.

    Shoulder disease is common in the athletic population and may arise as a consequence of a single traumatic episode or multiple repeated events. Associated labroligamentous injuries can result in substantial disability. Specific athletic and occupational activities result in predictable injury patterns. Imaging in general and magnetic resonance (MR) imaging, in particular, are vital in establishing the correct diagnosis and excluding common mimicking conditions, to ensure timely and appropriate management. In this review, the utility of MR imaging and MR arthrography will be explored in evaluation of shoulder disease, taking into account normal variants of the labroligamentous complex. Subsequently, broad categories of labral lesions and instability, external and internal impingement, as well as nerve entrapment syndromes, will be discussed, while emphasizing their imaging findings in the clinical context and illustrating key features. More recent concepts of internal impingement and secondary subacromial impingement will also be clarified. © RSNA, 2016.

    As with any child participating in sports, the safety of The Special Olympian participating in athletics is paramount. The preparticipation medical clearance is necessary to ensure these athletes' safety. In response to evidence that 15% of all individuals with Down syndrome have atlanto-occipital and/or atlanto-axial instability or subluxation, the Special Olympics Inc have additionally mandated preparticipation spine clearance for all individuals with Down syndrome. Spine clearance for the Special Olympian is challenging for the healthcare provider. In addition, controversy has arisen surrounding The Special Olympics Inc policy statement. The purposes of this article are to provide healthcare providers with a review of atlanto-occipital and atlanto-axial instability and subluxation, review spine clearance guidelines, discuss the details and controversy surrounding The Special Olympics Inc mandate, and provide recommendations on how to improve screening and ensure safety of the participants based on the current medical literature.

    McCune-Albright syndrome (MAS) is a disease of noninheritable, genetic origin defined by the triad of café-au-lait pigmentation of the skin, precocious puberty, and polyostotic fibrous dysplasia. This syndrome, which affects young girls primarily, has also been reported with other endocrinopathies, and rarely with acromegaly and hyperprolactinemia. The fibrous dysplasia in MAS is of the polyostotic type and, apart from the characteristic sites such as the proximal aspects of the femur and the pelvis, the craniofacial region is frequently involved. A male patient with MAS presented with juvenile gigantism, precocious puberty, pituitary adenoma-secreting growth hormone and prolactin, hypothalamic pituitary gonadal and thyroid dysfunction, and polyostotic fibrous dysplasia causing optic nerve compression.

    Demographics of human aging are rapidly changing. As illustrated in the biomedicalization of aging, an ever increasing number of older adults is affected by a variety of clinical conditions and diseases, including vascular stiffening, sarcopenia, physical disability, and poor quality of life. One population that is situated in the opposite end of the health and functional spectrum to the sedentary frail elderly is Masters athletes. These older competitive athletes are endowed with substantial functional capacity, overall long-term health, high motivation, and psychosocial outlook. Masters athletes are combating the dogma and negative stereotypes of older adults and aging. From the scientific standpoint, examining Masters athletes can provide insight into preventive gerontology, primary prevention of age-related diseases and dysfunctions, and exercise-based medical practices. Moreover, the study on Masters athletes is simply joyous and entertaining as they often remind us what can be possible in aging. © 2017 S. Karger AG, Basel.

    [Purpose] The purpose of this study was to examine the causal relationships between the psychological acceptance process of athletic injury and athletic-rehabilitation behavior. [Subjects] One hundred forty-four athletes who had injury experiences participated in this study, and 133 (mean age = 20.21 years, SD = 1.07; mean weeks without playing sports = 7.97 weeks, SD = 11.26) of them provided valid questionnaire responses which were subjected to analysis. [Methods] The subjects were asked to answer our originally designed questionnaire, the Psychosocial Recovery Factor Scale (PSRF-S), and two other pre-existing scales, the Athletic Injury Psychological Acceptance Scale and the Athletic-Rehabilitation Dedication Scale. [Results] The results of factor analysis indicate “emotional stability”, “social competence in the team”, “temporal perspective”, and “communication with the teammates” are factors of the PSRF-S. Lastly, the causal model in which psychosocial recovery factors are mediated by psychological acceptance of athletic injury, and influence on rehabilitation behaviors, was examined using structural equation modeling (SEM). The results of SEM indicate that the factors of emotional stability and temporal perspective are mediated by the psychological acceptance of the injury, which positively influences athletic-rehabilitation dedication. [Conclusion] The causal model was confirmed to be valid. PMID:25202190

      An organizational climate is largely based on an employee's perceptions of the working conditions in which he or she engages regularly. A multifaceted concept, the organizational climate is often formed by perceptions of employee welfare, rewards, and support. Achieving work-life balance is also a part of the climate.   To learn collegiate athletic trainers' perceptions of organizational climate and specifically how it may pertain to their work-life balance.   Phenomenologic study.   Collegiate practice setting.   Thirty athletic trainers working in the collegiate athletics setting took part in 1-on-1 phone interviews. The participants were 30.5 (interquartile range [IQR] = 7.75) years old and had been certified for 7 (IQR = 5) years and at their current position for 4 (IQR = 3) years.   Participants completed a phone interview that followed a semistructured framework. All transcribed interviews were analyzed using a phenomenologic approach. Researcher triangulation, expert review, and data saturation were used to establish credibility.   Athletic trainers working in the collegiate athletics setting who had positive perceptions of their work-life balance described their organizational climate as family friendly. Our participants' supervisors allowed for autonomy related to work scheduling, which provided opportunities for work-life balance. These athletic trainers believed that they worked in a climate that was collegial, which was helpful for work-life balance. In addition, the importance of placing family first was part of the climate.   The perceptions of our participants revealed a climate of family friendliness, supervisor support, and collegiality among staff members, which facilitated the positive climate for work-life balance. The mindset embraced the importance of family and recognized that work did not always have to supersede personal priorities.

    2011-01-01

    Context: Membership in the National Athletic Trainers' Association (NATA) has declined in recent years, generating much debate about professional commitment. Objective: To compare the contributing factors of job satisfaction and intention to leave athletic training of certified athletic trainers (ATs) employed in National Collegiate Athletic Association (NCAA) institutions. Design: Cross-sectional study. Setting: A link to a Web-based questionnaire containing the Spector Job Satisfaction Survey (JSS) and an original Intention to Leave Survey (ITLS) was distributed by e-mail to 1003 certified members of the National Athletic Trainers' Association. Patients or Other Participants: A total of 191 certified members of the NATA employed in a college or university setting in a primarily clinical capacity; representing all NCAA divisions; and having the job title of head athletic trainer, associate/assistant athletic trainer, or graduate assistant/intern athletic trainer. Main Outcome Measure(s): We used separate 3 × 3 factorial analyses of variance to compare the mean scores of each JSS subscale and of the ITLS with NCAA division and job title. A stepwise multiple regression was used to determine the strength of the relationships between the JSS subscales and the ITLS. Results: We found differences for job title in the subscales of Fringe Benefits (F2,182 = 7.82, P = .001) and Operating Conditions (F2,182 = 12.01, P < .001). The JSS subscale Nature of Work was the greatest indicator of intention to leave (β = −0.45). Conclusions: We found a strong negative correlation between various facets of job satisfaction and intention to leave athletic training. The NCAA division seemed to have no effect on an individual's job satisfaction or intention to leave the profession. In addition, only Fringe Benefits and Operating Conditions seemed to be affected by job title. The ATs had similar levels of job satisfaction regardless of NCAA division, and their job titles were not a

    Protein conformational changes are commonly associated with the formation of protein complexes. The non-catalytic death effector domains (DEDs) mediate protein-protein interactions in a variety of cellular processes, including apoptosis, proliferation and migration, and glucose metabolism. Here, using NMR residual dipolar coupling (RDC) data, we report a conformational change in the DED of the phosphoprotein enriched in astrocytes, 15 kDa (PEA-15) protein in the complex with a mitogen-activated protein (MAP) kinase, extracellular regulated kinase 2 (ERK2), which is essential in regulating ERK2 cellular distribution and function in cell proliferation and migration. The most significant conformational change in PEA-15 happens at helices α2, α3, and α4, which also possess the highest flexibility among the six-helix bundle of the DED. This crucial conformational change is modulated by the D/E-RxDL charge-triad motif, one of the prominent structural features of DEDs, together with a number of other electrostatic and hydrogen bonding interactions on the protein surface. Charge-triad motif promotes the optimal orientation of key residues and expands the binding interface to accommodate protein-protein interactions. However, the charge-triad residues are not directly involved in the binding interface between PEA-15 and ERK2.

    Cushing's syndrome (CS) may develop at any time in childhood. In the neonatal period, the major cause is the overactivation of adrenal cells within the context of McCune-Albright syndrome (MAS). The hypercorticism usually appears with other clinical signs of MAS. We report here a case of isolated neonatal CS as the initial evidence of MAS. This newborn girl was referred to our pediatric endocrine unit at the age of 3 months for hypotonia and growth retardation. Clinical examination revealed facial plethora, moon face, and swollen limbs. Laboratory data demonstrated ACTH-independent CS. Magnetic resonance imaging showed moderate bilateral adrenal hyperplasia, though more marked in the left adrenal gland, without nodules. This peripheral hypercorticism without well-defined adrenal tumor was suggestive of MAS, although no other signs like precocious puberty or café-au-lait spots were found. An activating Gsalpha gene mutation was found on DNA extracted from blood. Because MAS is a somatic disease, usually with unilateral effects, we tried to remove only the larger adrenal gland, where the mutation was demonstrated. This female newborn later developed the classical triad of MAS, reinforcing this diagnosis. Cushing's syndrome in infants, even when isolated, may suggest a diagnosis of MAS. Copyright 2009 S.

    Mechanical loading improves bone mineral density (BMD) and strength while decreasing fracture risk. Cross-sectional studies show that exercise advantage is lost in oligo-amenorrheic athletes (OA). Longitudinal studies examining the opposing effects of exercise and hypogonadism on bone are lacking in adolescents/young adults. Evaluate differences in bone accrual over 12 months in OA, eumenorrheic athletes (EA) and non-athletes (NA). We hypothesized that bone accrual would be lower in OA than EA and NA, with differences most pronounced at non-weight bearing trabecular sites. 27 OA, 29 EA, and 22 NA, 14-25 years old, completed 12-months of the prospective study. Athletes were weight-bearing endurance athletes. Subjects were assessed for areal BMD and bone mineral content (BMC) using DXA at the femoral neck, total hip, lumbar spine and whole body (WB). Failure load (a strength estimate) at the distal radius and tibia was assessed using microfinite element analysis of data obtained via high resolution peripheral quantitative computed tomography (HRpQCT). The primary analysis was a comparison of changes in areal BMD, BMC, and failure load across groups over 12-months at the respective sites. Groups did not differ for baseline age, height or BMI. Percent body fat was lower in both OA and EA compared to NA. OA attained menarche later than EA and NA. Over the follow-up period, OA gained 1.9 ± 2.7 kg of weight compared to 0.5 ± 2.4 kg and 0.8 ± 2.3 kg in EA and NA respectively (p = 0.09); 39% of OA resumed menses. Changes in BMD, BMD Z-scores, and tibial failure load over 12-months did not differ among groups.

    Identification of possible personal indicators of risk for challenging behaviour has generally been through association in cross-sectional prevalence studies, but few analyses have controlled for intercorrelation between potential risk factors. The aim was to investigate the extent to which gender, age, presence of the triad of impairments characteristic of autism and level of adaptive behaviour were independently associated with level of challenging behaviour among adults with intellectual disabilities. Five datasets were merged to produce information on challenging behaviour, adaptive behaviour, presence of the triad of impairments, gender and age of 818 adults. Variables were entered into a multivariate linear regression, which also tested the interaction between the presence of the triad of impairments and level of adaptive behaviour. Presence of the triad of impairments, level of adaptive behaviour, their interaction, and age, but not gender, significantly and independently contributed to the prediction of challenging behaviour. Presence/absence of the triad of impairments moderated the effect of adaptive behaviour on challenging behaviour. The inverse relationship found in the absence of the triad of impairments was virtually removed when present. This study has shown that it is necessary to control for intercorrelation between potential risk factors for challenging behaviour and to explore how interaction between them might moderate associations. © 2012 The Author.

  13. Functional nerve disorders in the athlete's foot, ankle, and leg.

    Baxter, D E

    1993-01-01

    Although neuropathies in the athlete's foot, ankle, and leg are uncommon, they are often underdiagnosed, primarily because of the complex interplay of causative factors. The physician should be aware of the possible occurrence of these neuropathies, and should be familiar with the anatomy and course of the nerves. Often, the problem only occurs during functional activity and cannot be demonstrated during the routine static examination. Other problems should also be considered when there is the possibility of a nerve compression syndrome. Metabolic processes, such as diabetes or abuse of alcohol, can certainly cause neuropathies. A double crush syndrome or pain from a higher source should also be considered. Finally, if surgery is done for chronic problems, only the area of constriction should be released, without interfering with the nerve itself. Release the fascia but leave the perineural fat intact. If instability is a factor, the joint should also be stabilized.

  15. The association between prune belly syndrome and dental anomalies: a case report

    PubMed Central

    2012-01-01

    Background Prune belly syndrome is a rare condition produced by an early mesodermal defect that causes abdominal abnormalities. However, the literature indicates that disturbances related to ectodermal development may also be present. This is the first case report in the literature to suggest that dental abnormalities are part of the broad spectrum of clinical features of prune belly syndrome. Because the syndrome causes many serious medical problems, early diagnosis of abnormalities involving the primary and permanent dentitions are encouraged. Case presentation The authors report the clinical case of a 4-year-old Caucasian boy with prune belly syndrome. In addition to the triad of abdominal muscle deficiency, abnormalities of the gastrointestinal and urinary tracts, and cryptorchidism, a geminated mandibular right central incisor, agenesis of a mandibular permanent left incisor, and congenitally missing primary teeth (namely, the mandibular right and left lateral incisors) were noted. Conclusion This original case report about prune belly syndrome highlights the possibility that dental abnormalities are a part of the broad spectrum of clinical features of the syndrome. Therefore, an accurate intra-oral clinical examination and radiographic evaluation are required for patients with this syndrome in order to provide an early diagnosis of abnormalities involving the primary and permanent dentitions.

    Athletes' retention of information conveyed in coaches' feedback during training was examined, considering the nature of the information transmitted by each coach (extensions, total number of ideas transmitted, and total number of repeated ideas), athletes' characteristics, (ages, genders, school levels, and practice levels), and athletes' perceptions (relevance and acceptance of coaches' information, task motivational levels, and athletes' attention levels). Participants were 193 athletes (79 boys, 114 girls; 9 to 13 years of age) and 6 coaches. Feedback was both audio and video recorded and all athletes were interviewed. All coaches' feedback and athletes' recollections were subjected to content analysis. Information was completely retained in 31.60% of feedback episodes. Athletes' mean per-episode information retention was 63.0%. Three variables appeared to b e predictiveathletes' retention: athletes' practice levels (p = -.25), attention to coaches' provision of feedback (P = .17), and the number of different ideas transmitted by each coach (P = -.90).

  19. Dietary recommendations and athletic menstrual dysfunction.

    PubMed

    Manore, Melinda M

    2002-01-01

    Exercise-induced or athletic menstrual dysfunction (amenorrhoea, oligomenorrhoea, anovulation, luteal phase deficiency, delayed menarche) is more common in active women and can significantly affect health and sport performance. Although athletic amenorrhoea represents the most extreme form of menstrual dysfunction, other forms can also result in suppressed estrogen levels and affect bone health and fertility. A number of factors, such as energy balance, exercise intensity and training practices, bodyweight and composition, disordered eating behaviours, and physical and emotional stress levels, may contribute to the development of athletic menstrual dysfunction. There also appears to be a high degree of individual variation with respect to the susceptibility of the reproductive axis to exercise and diet-related stresses. The dietary issues of the female athlete with athletic menstrual dysfunction are similar to those of her eumenorrhoeic counterpart. The most common nutrition issues in active women are poor energy intake and/or poor food selection, which can lead to poor intakes of protein, carbohydrate and essential fatty acids. The most common micronutrients to be low are the bone-building nutrients, especially calcium, the B vitamins, iron and zinc. If energy drain is the primary contributing factor to athletic menstrual dysfunction, improved energy balance will improve overall nutritional status and may reverse the menstrual dysfunction, thus returning the athlete to normal reproductive function. Because bone health can be compromised in female athletes with menstrual dysfunction, intakes of bone-building nutrients are especially important. Iron and zinc are typically low in the diets of female athletes if meat products are avoided. Adequate intake of the B vitamins is also important to ensure adequate energy production and the building and repair of muscle tissue. This review briefly discusses the various factors that may affect athletic menstrual dysfunction

    Ulnar sided wrist pain is a common site for upper extremity disability. Ulnar impaction syndrome results in a spectrum of triangular fibrocartilage complex (TFCC) injuries and associated lunate, triquetrum, and ligamentous damage. Patients commonly present with insidious ulnar sided wrist pain and clicking, and a history of trauma or repetitive axial loading and rotation. In this case series, three patients presented to a sports chiropractor for evaluation and were subsequently diagnosed with ulnar impaction syndrome. Treatment strategies consist of conservative management, arthroscopic debridement or repair, arthroscopic wafer procedure, or ulnar shortening osteotomy. For the athlete, intervention should be individualized and sport-specific, considering athletic priorities, healing potential, return to play, and long-term health concerns.

    AIM: To investigate the association between sports hernias and femoroacetabular impingement (FAI) in athletes. METHODS: PubMed, MEDLINE, CINAHL, Embase, Cochrane Controlled Trials Register, and Google Scholar databases were electronically searched for articles relating to sports hernia, athletic pubalgia, groin pain, long-standing adductor-related groin pain, Gilmore groin, adductor pain syndrome, and FAI. The initial search identified 196 studies, of which only articles reporting on the association of sports hernia and FAI or laparoscopic treatment of sports hernia were selected for systematic review. Finally, 24 studies were reviewed to evaluate the prevalence of FAI in cases of sports hernia and examine treatment outcomes and evidence for a common underlying pathogenic mechanism. RESULTS: FAI has been reported in as few as 12% to as high as 94% of patients with sports hernias, athletic pubalgia or adductor-related groin pain. Cam-type impingement is proposed to lead to increased symphyseal motion with overload on the surrounding extra-articular structures and muscle, which can result in the development of sports hernia and athletic pubalgia. Laparoscopic repair of sports hernias, via either the transabdominal preperitoneal or extraperitoneal approach, has a high success rate and earlier recovery of full sports activity compared to open surgery or conservative treatment. For patients with FAI and sports hernia, the surgical management of both pathologies is more effective than sports pubalgia treatment or hip arthroscopy alone (89% vs 33% of cases). As sports hernias and FAI are typically treated by general and orthopedic surgeons, respectively, a multidisciplinary approach for diagnosis and treatment is recommended for optimal treatment of patients with these injuries. CONCLUSION: The restriction in range of motion due to FAI likely contributes to sports hernias; therefore, surgical treatment of both pathologies represents an optimal therapy. PMID:26380829

    OBJECT Sport-related concussion (SRC) is a major public health problem. Approximately 90% of SRCs in high school athletes are transient; symptoms recover to baseline within 1 week. However, a small percentage of patients remain symptomatic several months after injury, with a condition known as postconcussion syndrome (PCS). The authors aimed to identify risk factors for PCS development in a cohort of exclusively young athletes (9-18 years of age) who sustained SRCs while playing a sport. METHODS The authors conducted a retrospective case-control study by using the Vanderbilt Sports Concussion Clinic database. They identified 40 patients with PCS and matched them by age at injury and sex to SRC control patients (1 PCS to 2 control). PCS patients were those experiencing persistent symptoms at 3 months after an SRC. Control patients were those with documented resolution of symptoms within 3 weeks of an SRC. Data were collected in 4 categories: 1) demographic variables; 2) key medical, psychiatric, and family history; 3) acute-phase postinjury symptoms (at 0-24 hours); and 4) subacute-phase postinjury features (at 0-3 weeks). The chi-square Fisher exact test was used to assess categorical variables, and the Mann-Whitney U-test was used to evaluate continuous variables. Forward stepwise regression models (Pin = 0.05, Pout = 0.10) were used to identify variables associated with PCS. RESULTS PCS patients were more likely than control patients to have a concussion history (p = 0.010), premorbid mood disorders (p = 0.002), other psychiatric illness (p = 0.039), or significant life stressors (p = 0.036). Other factors that increased the likelihood of PCS development were a family history of mood disorders, other psychiatric illness, and migraine. Development of PCS was not predicted by race, insurance status, body mass index, sport, helmet use, medication use, and type of symptom endorsement. A final logistic regression analysis of candidate variables showed PCS to be

    Importance Every state in the United States has passed legislation for sport-related concussion, making this health issue important for physicians and other health care professionals. Safely returning athletes to sport after concussion relies on accurately determining when their symptoms resolve. Objective To evaluate baseline concussion-like symptom reporting in uninjured adolescent student athletes. Design, Setting, and Participants In this cross-sectional, observational study, we studied 31 958 high school athletes from Maine with no concussion in the past 6 months who completed a preseason baseline testing program between 2009 and 2013. Results Symptom reporting was more common in girls than boys. Most students with preexisting conditions reported one or more symptoms (60%-82% of boys and 73%-97% of girls). Nineteen percent of boys and 28% of girls reported having a symptom burden resembling an International Classification of Diseases, 10th Revision (ICD-10) diagnosis of postconcussional syndrome (PCS). Students with preexisting conditions were even more likely to endorse a symptom burden that resembled PCS (21%-47% for boys and 33%-72% for girls). Prior treatment of a psychiatric condition was the strongest independent predictor for symptom reporting in boys, followed by a history of migraines. For girls, the strongest independent predictors were prior treatment of a psychiatric condition or substance abuse and attention-deficit/hyperactivity disorder. The weakest independent predictor of symptoms for both sexes was history of prior concussions. Conclusions and Relevance In the absence of a recent concussion, symptom reporting is related to sex and preexisting conditions. Consideration of sex and preexisting health conditions can help prevent misinterpretation of symptoms in student athletes who sustain a concussion. PMID:26457403

    We aimed to investigate eating disorder pathology in German elite adolescent athletes. Evidence suggests that eating disorder pathology is more common in adult elite sports, especially in female athletes and in sports emphasizing leanness. There is a scarcity of studies in elite adolescent athletes who are in a vulnerable developmental stage and are affected by general as well as sport-specific risk factors. Our data was derived from the German Young Olympic Athletes' Lifestyle and Health Management Study (GOAL) which conducted a survey in 1138 elite adolescent athletes. In this sample, we assessed body weight, weight control behavior, body acceptance and screened overall for core symptoms of eating disorders, depression and anxiety. We performed a tree analysis to identify high risk groups for eating disorder pathology. High risk groups comprised (a) athletes competing in weight dependent sports, and among athletes competing in disciplines other than weight dependent sports (b) athletes who are high on negative affectivity, (c) female athletes and (d) male athletes competing in endurance, technical or power sports. Athletes competing in weight dependent disciplines reported wide spread use of compensatory behaviors to influence body weight. Athletes reporting eating disorder pathology showed higher levels of depression and anxiety than athletes without eating disorder pathology. Increased psychosocial burden in athletes with eating disorder pathology suggests that eating disorder symptoms should not be accepted as an unproblematic and functional part of elite sports. The prevention and management of eating disorder pathology is especially important in weight dependent sports. © 2016 Wiley Periodicals, Inc.

    For athletes, the main purpose of nutrition is to ensure the compensation of increased energy consumption and the need for nutrients in the athlete's body, thereby enabling maximum adaptation to physical loads. The aim of this study was to determine the habits of highly trained endurance athletes depending on sports type, sex and age in order to improve the planning and management of the training of athletes using targeted measures. In 2009-2012, the dietary habits of 146 endurance athletes were analyzed. The actual diet of Lithuania endurance athletes was investigated using a 24-h dietary survey method. Data on the athletes' actual diet were collected for the previous day. It was found that 80.8% of endurance athletes used lower-than-recommended amounts of carbohydrates in their diet, and more than 70% of athletes used higher-than-recommended levels of fat, saturated fatty acids, and cholesterol. The diet of female athletes was low in carbohydrates, dietary fiber, protein, omega-3 fatty acids, B vitamins, potassium, calcium, phosphorus, iron, manganese, and zinc. Athletes aged 14-18 years tended to consume quantities of protein that were either lower than recommended or excessive. The diet of highly trained endurance athletes does not fully meet their requirements and in this situation cannot ensure maximum adaptation to very intense and/or long-duration physical loads. The diet of highly trained endurance athletes must be optimized, adjusted and individualized. Particular attention should be focused on female athletes.

J Strength Cond Res 32(5): 1181-1196, 2018-This study provides the first empirical evidence of how strongman athletes taper for strongman competitions. Strongman athletes (n = 454) (mean ± SD: 33.2 ± 8.0 years, 178.1 ± 10.6 cm, 108.6 ± 27.9 kg, 12.6 ± 8.9 years general resistance training, 5.3 ± 5.0 years strongman implement training) completed a self-reported 4-page internet survey on tapering practices. Analysis by sex (male and female), age (≤30 and >30 years), body mass (≤105 and >105 kg), and competitive standard (local/regional amateur, national amateur and professional) was conducted. Eighty-seven percent (n = 396) of strongman athletes reported that they used a taper. Athletes stated that their typical taper length was 8.6 ± 5.0 days, with the step taper the most commonly performed taper (52%). Training volume decreased during the taper by 45.5 ± 12.9%, and all training ceased 3.9 ± 1.8 days out from competition. Typically, athletes reported that training frequency and training duration stayed the same or decreased and training intensity decreased to around 50% in the last week. Athletes generally stated that tapering was performed to achieve recovery, rest, and peak performance; the deadlift, yoke walk, and stone lifts/work took longer to recover from than other lifts; assistance exercises were reduced or removed in the taper; massage, foam rolling, nutritional changes, and static stretching were strategies used in the taper; and, poor tapering occurred when athletes trained too heavy/hard or had too short a taper. These data will assist strongman athletes and coaches in the optimization of tapering variables leading to more peak performances. Future research could investigate the priming and preactivation strategies strongman athletes use on competition day.

    Background Although Perceived Stress Scale (PSS, Cohen, Kamarack & Mermelstein, 1983) has been validated and widely used in many domains, there is still no validation in sports by comparing athletes and non-athletes and examining related psychometric indices. Purpose The purpose of this study was to examine the measurement invariance of PSS between athletes and non-athletes, and examine construct validity and reliability in the sports contexts. Methods Study 1 sampled 359 college student-athletes (males = 233; females = 126) and 242 non-athletes (males = 124; females = 118) and examined factorial structure, measurement invariance and internal consistency. Study 2 sampled 196 student-athletes (males = 139, females = 57, Mage = 19.88 yrs, SD = 1.35) and examined discriminant validity and convergent validity of PSS. Study 3 sampled 37 student-athletes to assess test-retest reliability of PSS. Results Results found that 2-factor PSS-10 fitted the model the best and had appropriate reliability. Also, there was a measurement invariance between athletes and non-athletes; and PSS positively correlated with athletic burnout and life stress but negatively correlated with coping efficacy provided evidence of discriminant validity and convergent validity. Further, the test-retest reliability for PSS subscales was significant (r = .66 and r = .50). Discussion It is suggested that 2-factor PSS-10 can be a useful tool in assessing perceived stress either in sports or non-sports settings. We suggest future study may use 2-factor PSS-10 in examining the effects of stress on the athletic injury, burnout, and psychiatry disorders. PMID:27994983

    Synthesis of new PDT triads that incorporate a tumor-killing porphyrin with large two-photon cross-section for 150 fs laser pulses (2000 GM) in the Near-infrared (NIR) at 840 nm, a NIR imaging agent, and a small peptide that targets over-expressed EGF receptors on the tumor surface. This triad formulation has been optimized over the past year to treat FADU Head and Neck SCC xenograft tumors in SCID mice. Effective PDT triad dose (1-10 mg/Kg) and laser operating parameters (840 nm, 15-45 min, 900 mW) have been established. Light, dark and PDT treatment toxicities were determined, showing no adverse effects. Previous experiments in phantom and mouse models indicate that tumors can be treated directly through the skin to effective depths between 2 and 5 cm. Treated mice demonstrated rapid tumor regression with some complete cures in as little as 15-20 days. No adverse effects were observed in any healthy tissue through which the focused laser beam passed before reaching the tumor site, and excellent healing occurred post treatment including rapid hair re-growth. Not all irradiation protocols lead to complete cures. Since two-photon PDT is carried out by rastering focused irradiation throughout the tumor, there is the possibility that as the treatment depth increases, some parts of the tumor may escape irradiation due to increased scattering, thus raising the possibility that tumor re-growth could be triggered by small islands of untreated cells, especially at the rapidly growing tumor margins, a problem we hope to alleviate by using image-guided two-photon PDT.

Methods and Results A retrospective cohort of all male athletes who participated in varsity athletics at a National Collegiate Athletic Association Division I university between 1999–2012 was examined through chart review. Mandatory annual preparticipation physical examinations included blood pressure, body mass index, medication use, and supplement use. Prevalence of hypertension was compared between football and non-football athletes. A mixed-effects linear regression model examined change in blood pressure over time. 636 collegiate athletes, including 323 football players, were identified. In the initial year of athletic participation, 19.2% of football athletes had hypertension and 61.9% had prehypertension. The prevalence of hypertension was higher among football athletes than non-football athletes in their initial (19.2% vs. 7.0%, P< 0.001) and final (19.2% vs. 10.2%, P=0.001) years of athletic participation. In adjusted analyses, the odds of hypertension was higher among football athletes in the initial year (AOR 2.28, 95% CI 1.21 to 4.30) but not the final year (AOR 1.25, 95% CI 0.69 to 2.28). Over the course of their collegiate career, football athletes had an annual decrease in systolic blood pressure (−0.82 mmHg, P=0.002), while non-football athletes did not (0.18 mmHg, P=0.58). Conclusions Hypertension and prehypertension were common among collegiate football athletes, and football athletes were more likely to have hypertension than male non-football athletes. This presents a potential cardiovascular risk in a young population of athletes. Strategies for increasing awareness, prevention and treatment are needed. PMID:24221829

  16. Athlete's Foot: Clinical Update.

    PubMed

    Ramsey, M L

    1989-10-01

    In brief: Athletes are particularly prone to athlete's foot because they are generally more exposed than others to conditions that encourage fungal growth, eg, communal showers and locker rooms. Diagnosis of athlete's foot rests on clinical suspicion and laboratory testing. Treatment may consist of topical antifungal agents and, for more resistant cases, oral griseofulvin. Preventive measures include keeping the feet dry, wearing nonocclusive leather shoes or sandals and absorbent cotton socks, and applying talcum or antifungal powder at least twice daily.

    2017-01-01

    Context: Increased sport participation and sport-related concussion incidence has led to an emphasis on having an appropriate medical professional available to high school athletes. The medical professional best suited to provide medical care to high school athletes is a certified athletic trainer (AT). Access to an AT may influence the reporting of sport-related concussion in the high school athletic population; however, little is known about how the presence of an AT affects concussion knowledge, prevention, and recognition. Objective: To evaluate knowledge of concussion and reporting behaviors in high school athletes who did or did not have access to an AT. Design: Cross-sectional study. Setting: Survey. Patients or Other Participants: A total of 438 athletes with access to an AT and 277 without access to an AT. Intervention(s): A validated knowledge-of-concussion survey consisting of 83 items addressing concussion history, concussion knowledge, scenario questions, signs and symptoms of a concussion, and reasons why an athlete would not report a concussion. The independent variable was access to an AT. Main Outcome Measure(s): We examined the proportion of athletes who correctly identified knowledge of concussion, signs and symptoms of concussion, and reasons why high school student-athletes would not disclose a potential concussive injury by access to an AT. Frequency statistics, χ2 tests, independent t tests, and linear regression were conducted to analyze the data. Results: The underreporting of concussion among high school athletes was 55%. Athletes with access to an AT had more knowledge of concussion than did athletes without such access (P ≤ .001). Chi-square tests did not demonstrate a significant relationship between AT access and a higher percentage reporting concussions. Conclusions: High school athletes with access to an AT had more concussion knowledge, but they did not report suspected concussions to an authority figure more frequently than

    Context: The athletics model, in which athletic training clinical programs are part of the athletics department, is the predominant model in the collegiate athletic training setting. Little is known about athletic trainers' (ATs') perceptions of this model, particularly as it relates to organizational hierarchy. Objective: To explore the perceived benefits of and barriers in the athletics model. Design: Qualitative study. Setting: National Collegiate Athletic Association Divisions I and III. Patients or Other Participants: Eight full-time ATs (5 men, 3 women; age = 41 ± 13 years, time employed at the current institution = 14 ± 14 years, experience as a certified AT = 18 ± 13 years) working in the collegiate setting using the athletics model. Data Collection and Analysis: We conducted semistructured interviews via telephone or in person and used a general inductive approach to analyze the qualitative data. Multiple-analyst triangulation and peer review established trustworthiness. Results: Two benefits and 3 barriers emerged from the data. Role identity emerged as a benefit that occurred with role clarity, validation, and acceptance of the collegiate AT personality. Role congruence emerged as a benefit of the athletics model that occurred with 2 lower-order themes: relationship building and physician alignment and support. Role strain, staffing concerns, and work-life conflict emerged as barriers in the athletics model. Role strain occurred with 2 primary lower-order themes: role incongruity and role conflict. Conclusions: The athletics model is the most common infrastructure for employing ATs in collegiate athletics. Participants expressed positive experiences via character identity, support, trust relationships, and longevity. However, common barriers remain. To reduce role strain, misaligning values, and work-life conflict, ATs working in the athletics model are encouraged to evaluate their relationships with coaches and their supervisor and consider team

    PubMed

    Vinci, D M

    1998-09-01

    This paper presents an overview of the Husky Sport Nutrition Program at the University of Washington. This program is a component of the Department of Intercollegiate Athletics Total Student-Athlete Program, an NCAA-sponsored CHAMPS/Life Skills Program that provides life skills assistance to student-athletes. Successful integration of a sport nutrition program requires an understanding of the athletic culture, physiological milestones, and life stressors faced by college athletes. The sport nutritionist functions as an educator, counselor, and administrator. Team presentations and individual nutrition counseling provide athletes with accurate information on healthy eating behaviors for optimal performance. For women's sports, a multidisciplinary team including the sport nutritionist, team physician, clinical psychologist, and athletic trainer work to prevent and treat eating disorders. Case studies are presented illustrating the breadth of nutrition-related issues faced by a sport nutritionist working with college athletes.

    Few studies have documented expected time to return to athletic participation after stress fractures in elite athletes. Time to return to athletic participation after stress fractures would vary by site and severity of stress fracture. Retrospective cohort study. Level 3. All stress fractures diagnosed in a single Division I collegiate men's and women's track and field/cross-country team were recorded over a 3-year period. Site and severity of injury were graded based on Kaeding-Miller classification system for stress fractures. Time to return to full unrestricted athletic participation was recorded for each athlete and correlated with patient sex and site and severity grade of injury. Fifty-seven stress fractures were diagnosed in 38 athletes (mean age, 20.48 years; range, 18-23 years). Ten athletes sustained recurrent or multiple stress fractures. Thirty-seven injuries occurred in women and 20 in men. Thirty-three stress fractures occurred in the tibia, 10 occurred in the second through fourth metatarsals, 3 occurred in the fifth metatarsal, 6 in the tarsal bones (2 navicular), 2 in the femur, and 5 in the pelvis. There were 31 grade II stress fractures, 11 grade III stress fractures, and 2 grade V stress fractures (in the same patient). Mean time to return to unrestricted sport participation was 12.9 ± 5.2 weeks (range, 6-27 weeks). No significant differences in time to return were noted based on injury location or whether stress fracture was grade II or III. The expected time to return to full unrestricted athletic participation after diagnosis of a stress fracture is 12 to 13 weeks for all injury sites. Athletes with grade V (nonunion) stress fractures may require more time to return to sport.

    Low energy availability (EA) is suspected to be the underlying cause of both the Female Athlete Triad and the more recently defined syndrome, Relative Energy Deficiency in Sport (RED-S). The International Olympic Committee (IOC) defined RED-S as a syndrome of health and performance impairments resulting from an energy deficit. While the importance of adequate EA is generally accepted, few studies have attempted to understand whether low EA is associated with the health and performance consequences posited by the IOC. The purpose of this cross-sectional study was to examine the association of low EA with RED-S health and performance consequences in a large clinical population of female athletes. One thousand female athletes (15-30 years) completed an online questionnaire and were classified as having low or adequate EA. The associations between low EA and the health and performance factors listed in the RED-S models were evaluated using chi-squared test and the odds ratios were evaluated using binomial logistic regression (p<0.05). Athletes with low EA were more likely to be classified as having increased risk of menstrual dysfunction, poor bone health, metabolic issues, haematological detriments, psychological disorders, cardiovascular impairment and gastrointestinal dysfunction than those with adequate EA. Performance variables associated with low EA included decreased training response, impaired judgement, decreased coordination, decreased concentration, irritability, depression and decreased endurance performance. These findings demonstrate that low EA measured using self-report questionnaires is strongly associated with many health and performance consequences proposed by the RED-S models. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  3. Identification of the catalytic triad of the lipase/acyltransferase from Aeromonas hydrophila.

    1996-01-01

    Aeromonas hydrophila secretes a lipolytic enzyme that has several properties in common with the mammalian enzyme lecithin-cholesterol acyltransferase. We have recently shown that it is a member of a newly described group of proteins that contain five similar blocks of sequence arranged in the same order in their primary structures (C. Upton and J. T. Buckley, Trends Biochem. Sci. 233:178-179, 1995). Assuming that, like other lipases, these enzymes have a Ser-Asp-His catalytic triad, we used these blocks to predict which aspartic acid and histidine would be at the active site of the Aeromonas enzyme. Targeted residues were replaced with other amino acids by site-directed mutagenesis, and the effects on secretion and activity were assessed. Changing His-291 to asparagine completely abolished enzyme activity, although secretion by the bacteria was not affected. Only very small amounts of the D116N mutant appeared in the culture supernatant, likely because it is sensitive to periplasmic proteases it encounters en route. Assays of crude preparations containing this variant showed no detectable enzyme activity. We conclude that, together with Ser-16, which we have identified previously, Asp-116 and His-291 compose the catalytic triad of the enzyme. PMID:8606184

  4. A "weight of evidence" approach for the integration of environmental "triad" data to assess ecological risk and biological vulnerability.

    2008-07-01

    A new Expert Decision Support System (EDSS) that can integrate Triad data for assessing environmental risk and biological vulnerability at contaminated sites has been developed. Starting with ecosystem relevance, the EDSS assigns different weights to the results obtained from Triad disciplines. The following parameters have been employed: 1) chemical soil analyses (revealing the presence of potentially dangerous substances), 2) ecotoxicological bioassays (utilizing classical endpoints such as survival and reproduction rates), 3) biomarkers (showing sublethal pollutant effects), and 4) ecological parameters (assessing changes in community structure and functions). For each Triad discipline, the EDSS compares the data obtained at the studied field sites with reference values and calculates different 0-1 indexes (e.g., Chemical Risk Index, Ecotoxicological Risk Index, and Ecological Risk Index). The EDSS output consists of 3 indexes: 1) Environmental Risk index (EnvRI), quantifying the levels of biological damage at population-community level, 2) Biological Vulnerability Index (BVI), assessing the potential threats to biological equilibriums, and 3) Genotoxicity Index (GTI), screening genotoxicity effects. The EDSS has been applied in the integration of a battery of Triad data obtained during the European Union-funded Life Intervention in the Fraschetta Area (LINFA) project, which has been carried out in order to estimate the potential risk from soils of a highly anthropized area (Alessandria, Italy) mainly impacted by deposition of atmospheric pollutants. Results obtained during 4 seasonal sampling campaigns (2004-2005) show maximum values of EnvRI in sites A and B (characterized by industrial releases) and lower levels in site D (affected by vehicular traffic emissions). All 3 potentially polluted sites have shown high levels of BVI and GTI, suggesting a general change from reference conditions (site C).

    To review the recent literature (over the past 18 months) regarding psychosocial challenges and clinical concerns among adolescent athletes, and to address the advances made in understanding adolescent athletes' coping processes. Coping research has moved from identifying discrete stressors and coping strategies to examining the processes of coping over time. Parents and coaches play an important role in young athletes' sport experiences and athletes' use and development of coping strategies. In terms of clinical concerns, findings regarding the prevalence of disordered eating have been equivocal. However, disordered eating may be of greater concern among athletes participating in 'leanness' sports. Sport participation may contribute to increased alcohol consumption among adolescent athletes but decreased use of drugs and smoking cigarettes, while steroid use appears to be relatively rare compared with athletes' use of alcohol and cigarettes. The reviewed studies have implications for future research by identifying opportunities for intervention and education regarding clinical and nonclinical psychosocial challenges. Researchers have emphasized the importance of athletes' social context and relationships in coping with psychosocial challenges in sport. One concern is that adolescent athletes' disordered eating and substance use may reflect maladaptive coping. Experimental and intervention research is limited; however, incorporating members of athletes' social network into future research and interventions may be a practical avenue to achieving positive outcomes among adolescent athletes.

    Introduction Existing sleep questionnaires to assess sleep behaviors may not be sensitive in determining the unique sleep challenges faced by elite athletes. The purpose of the current study was to develop and validate the Athlete Sleep Behavior Questionnaire (ASBQ) to be used as a practical tool for support staff working with elite athletes. Methods 564 participants (242 athletes, 322 non-athletes) completed the 18-item ASBQ and three previously validated questionnaires; the Sleep Hygiene Index (SHI), the Epworth Sleepiness Scale (ESS) and the Pittsburgh Sleep Quality Index (PSQI). A cohort of the studied population performed the ASBQ twice in one week to assess test-retest reliability, and also performed sleep monitoring via wrist-actigraphy. Results Comparison of the ASBQ with existing sleep questionnaires resulted in moderate to large correlations (r=0.32 - 0.69). There was a significant difference between athletes and non-athletes for the ASBQ global score (44±6 vs. 41±6, respectively, p<0.01) and for the PSQI, but not for the SHI or the ESS. The reliability of the ASBQ was acceptable (ICC=0.87) when re-tested within 7 days. There was a moderate relationship between ASBQ and total sleep time (r=-0.42). Conclusion The ASBQ is a valid and reliable tool that can differentiate the sleep practices between athletes and non-athletes, and offers a practical instrument for practitioners and/or researchers wanting to evaluate the sleep behaviors of elite athletes. The ASBQ may provide information on areas where improvements to individual athletes’ sleep habits could be made. PMID:29796200

    College students experience higher rates of gambling-related problems than most other population segments, including the general population. Although Division I (D1) athletes often have more at stake than the average student if and when they gamble (e.g., the potential to lose their athletic eligibility), relatively few studies have assessed the gambling behavior of this population and none have specifically assessed fantasy sports gambling. We conducted a study to examine gambling behavior (past-year gambling, gambling-related problems, and fantasy sport gambling) among a sample (N = 692) of college students at a private religiously affiliated university in the Southwest US. The sample for our study was unique in that approximately 30 % of the participants were D1 athletes. We compared the gambling behavior among three groups based on the athlete status: D1 athletes, club/intramural/recreational (CIR) athletes, and non-athletes (NAs). Compared to females in our sample, males observed higher rates of past year gambling, fantasy sports participation, fantasy sports gambling, and gambling-related problems. Among males, we found that CIR athletes observed the highest rates of past year gambling and fantasy sports participation and D1 athletes observed higher rates than NAs. We did not find differences in fantasy sport gambling and past year gambling-related problems based on athlete status in males or females.

  10. History and epidemiology of anabolic androgens in athletes and non-athletes.

    PubMed

    Kanayama, Gen; Pope, Harrison G

    2018-03-15

    The use of androgens, frequently referred to as anabolic-androgenic steroids (AAS), has grown into a worldwide substance abuse problem over the last several decades. Testosterone was isolated in the 1930s, and numerous synthetic androgens were quickly developed thereafter. Athletes soon discovered the dramatic anabolic effects of these hormones, and AAS spread rapidly through elite athletics and bodybuilding from the 1950s through the 1970s. However it was not until the 1980s that widespread AAS use emerged from the elite athletic world and into the general population. Today, the great majority of AAS users are not competitive athletes, but instead are typically young to middle-aged men who use these drugs primarily for personal appearance. AAS abuse has now become particularly prevalent in regions such as Scandinavia, the United States, Brazil, and British Commonwealth countries, but remains rare in countries such as China, Korea, and Japan - a pattern that reflects cultural differences in attitudes towards male muscularity.

  11. The Athletic Body.

    PubMed

    Edgar, Andrew

    2016-09-10

    This paper seeks to explore the attraction and the beauty of the contemporary athletic body. It will be suggested that a body shaped through muscular bulk and definition has come to be seen as aesthetically normative. This body differs from the body of athletes from the early and mid-twentieth century. It will be argued that the contemporary body is not merely the result of advances in sports science, but rather that it is expressive of certain meanings and values. The visual similarity of the contemporary athletic body and that of the comic book superhero suggests that both bodies carry a similar potential for narrative story-telling, and that their attraction is bound up with this narrative potential. The superhero and athlete live meaningful lives, pursuing clear and morally unambiguous goals. The aesthetic attraction of the body lies in its capacity to facilitate the articulation of a story of a meaningful life, and to do so in the face of the growing anomie and thus meaninglessness of life as experienced in contemporary society. Athleticism offers an illusion of meaning, serving to reproduce dominant justificatory narratives and social stereotypes. Yet, as an illusion of meaning, it may be challenged and negotiated, not least with respect to its bias towards a certain form of the male body. The female athletic body disrupts the illusion, opening up new existential possibilities, new ways of living and being, and thus new, and potentially disruptive, narratives.

    Insulin resistance syndromes without lipodystrophy are an infrequent and heterogeneous group of disorders with variable clinical phenotypes, associated with hyperglycemia and hyperinsulinemia. The three conditions related to mutations in the insulin receptor gene are leprechaunism or Donohue syndrome, Rabson-Mendenhall syndrome, and Type A syndrome. A case is presented on a patient diagnosed with type A insulin resistance, defined by the triad of extreme insulin resistance, acanthosis nigricans, and hyperandrogenism, carrying a heterozygous mutation in exon 19 of the insulin receptor gene coding for its tyrosine kinase domain that is crucial for the catalytic activity of the receptor. The molecular basis of the syndrome is reviewed, focusing on the structure-function relationships of the insulin receptor, knowing that the criteria for survival are linked to residual insulin receptor function. It is also pointed out that, although type A insulin resistance appears to represent a somewhat less severe condition, these patients have a high morbidity and their treatment is still unsatisfactory.

    2018-06-22

    Despite evidence that strength and conditioning (S&C) programs decrease injury risk and increase sport performance, young females are rarely offered S&C programs comparable to those of their male counterparts. The purpose of this study was to evaluate the current body of available literature regarding S&C in adolescent female athletes, describe potential benefits, and generate recommendations for S&C programs for female adolescent athletes. This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Systematic searches of the PubMed and Google Scholar databases were conducted using the following keywords: 'female athletes,' 'injury prevention,' 'adolescent,' 'physical fitness,' 'strength,' 'female adolescent,' and 'conditioning.' Studies included in this review evaluated the effectiveness of S&C protocols and/or the habits and attitudes of coaches and athletic trainers working with female adolescent athletes. Seven articles evaluating S&C programs for the adolescent female athlete were used as the basis for this systematic review. These articles described current protocols and/or factors that should be taken into account when designing S&C programs. The identified articles focused on improving the strength of adolescent female athletes, decreasing the risk of injury, and exposing female athletes to the benefits of S&C that are routinely afforded to their male counterparts. Despite the critical potential benefits of S&C training, such as improved landing mechanics, coaches and athletic trainers do not routinely implement S&C programs for female adolescent athletes. The lack of such programs is largely due to misconceptions surrounding female athletes, such as the perception that females fear bulking up. S&C programs for adolescent female athletes should incorporate stretching of the hip adductors, targeted hamstring, gluteal and quadriceps strengthening, and a synergistic adaptation model

  17. Hypertensive Medications in Competitive Athletes.

    PubMed

    Pelto, Henry

    Hypertension is the most common cardiovascular disease in athletes. It is an important cause of long-term morbidity and mortality, even in a fit, athletic population. Management options to reduce these long-term risks exist that have minimal impact on athletic performance. Identification and management of underlying lifestyle factors and diseases that may lead to secondary hypertension is critical. These include substance abuse, medications, and underlying medical conditions. After evaluation and management of these issues, medications can be used to reduce blood pressure. In the athletic population, first-line medication treatment should include ACE inhibitors, angiotensin II receptor blockers (ARB), and calcium channel blockers (CCB). The response to treatment should be followed closely to ensure adequate blood pressure control. Athletic participation in sports with high dynamic load should be limited in individuals with stage 2 hypertension or stage 1 hypertension with evidence of end organ damage.

Although some supplements do enhance athletic performance, many have no proven benefits and have adverse effects. Nutritional supplements are categorized into the following categories: I. Apparently Effective. II. Possibly Effective. III. Too Early To Tell. IV. Apparently Ineffective. This article will review 4 ergogenic supplements which are categorized in the first category--"Apparently Effective"--1) Buffer agents 2) Creatine 3) Caffeine and 4 Nitric Oxide. Given the widespread use of performance enhancing supplements, physicians, and dietitians should be prepared to counsel athletes about their effectiveness, safety and legality.

    Anecdotally, we know that students select graduate programs based on location, finances, and future career goals. Empirically, however, we lack information on what attracts a student to these programs. To gain an appreciation for the selection process of graduate study. Qualitative study. Postprofessional programs in athletic training (PPATs) accredited by the National Athletic Trainers' Association. A total of 19 first-year PPAT students participated, representing 13 of the 16 accredited PPAT programs. All interviews were conducted via phone and transcribed verbatim. Analysis of the interview data followed the procedures as outlined by a grounded theory approach. Trustworthiness was secured by (1) participant checks, (2) participant verification, and (3) multiple analyst triangulations. Athletic training students select PPAT programs for 4 major reasons: reputation of the program or faculty (or both), career intentions, professional socialization, and mentorship from undergraduate faculty or clinical instructors (or both). Participants discussed long-term professional goals as the driving force behind wanting an advanced degree in athletic training. Faculty and clinical instructor recommendations and the program's prestige helped guide the decisions. Participants also expressed the need to gain more experience, which promoted autonomy, and support while gaining that work experience. Final selection of the PPAT program was based on academic offerings, the assistantship offered (including financial support), advanced knowledge of athletic training concepts and principles, and apprenticeship opportunities. Students who attend PPAT programs are attracted to advancing their entry-level knowledge, are committed to their professional development as athletic trainers, and view the profession of athletic training as a life-long career. The combination of balanced academics, clinical experiences, and additional professional socialization and mentorship from the PPAT program

    The aims of this study were to compare proprioception in knee rotation in Olympic-level soccer players (N=18) with non-athletes (N=18), to explore between-limb differences in soccer players, and examine correlations between proprioception and years of playing, function, physical measures and skill level. The knee rotatory kinaesthetic device was used to present stimuli of different magnitudes to determine proprioceptive acuity for internal and external active rotation, and to measure active and passive rotation range of motion (ROM). Knee rotation strength was measured using a dynamometer. Proprioceptive acuity of the athletes was significantly (P=0.004) better than that of the non-athletes. Athletes displayed significantly less passive ROM (P=0.001), higher isometric muscle strength (P=0.006) and greater hop for distance (P=0.001) than non-athletes. No significant between-limb differences were found in the athletes in any objective outcome measure. Internal rotation proprioceptive acuity was negatively correlated with coach-rated ball skill (r=-0.52) and positively correlated with internal rotation ROM (r=0.59). Our findings suggest that highly trained athletes possess enhanced proprioceptive acuity and muscle strength that may be inherent, or may develop as a result of long-term athletic training.

    The purpose of this study was to determine the effects of high-intensity interval training (HIIT) on athletic performance in Taekwondo athletes. Thirty-three male and female collegiate Taekwondo athletes were randomly divided into a HIIT group (N.=16) or a high-intensity continuous running (HICR) group (N.=17). The HIIT group undertook training of high-intensity sprints interspersed with active rest periods whilst the HICR group participated in high-intensity running for a continuous period. Both groups completed 11 sessions over 4 weeks. Physique, body composition, Wingate anaerobic test and VO2max test were measured. The vertical jump test, agility T-test and sit-ups were used to assess physical fitness. Repeated measures ANCOVAs with sex as a covariate were applied and significant level was set at 0.05. Following 11 sessions of training, significant improvements in anaerobic peak power (P<0.05), relative peak power (P<0.05), and mean power (P<0.05) were observed only in HIIT group compared to HICR group. A greater improvement of aerobic capacity was observed in HIIT group (8.8%) compared to the HICR group (1.7%). In relation to physical fitness, the HIIT group improved in the vertical jump while the HICR group did not change. Both the HIIT and HICR groups showed greater improvements in T-test and sit-ups during the intervention period. This study shows the effectiveness of eleven sessions of HIIT in producing significant improvements in anaerobic capacity relevant to successful Taekwondo competition performance in collegiate Taekwondo athletes. This could inform the future planning of Taekwondo athletes' pre-competition training, specifically the influence of training intensity on anaerobic capacity.

    Background With environmental pollution increasing, interest in organic farming and organic foodstuffs has been growing all over the world. Data on organic food consumption by Lithuanian athletes is not yet available. This lack of data determined the aim of this study: to identify the particulars of organic foodstuff consumption among athletes. Methods In September–November 2012, we polled 158 of the best-performing athletes of the Olympic sports team through direct interviews. An approved questionnaire was used to identify the specifics of organic foodstuff consumption among athletes. Results The survey results showed that 97% of athletes consume organic foodstuffs, and 80% of athletes highlighted the positive impact of organic food on health. Nevertheless, a slim majority of athletes (51.7%) consume organic foodstuffs seldomly, 2–3 times per week. The range of organic foodstuffs consumed depends on the gender of athletes, and the consumption of some products depends on monthly incomes. Conclusions Survey results confirm the need for the production and expansion of the variety of organic foodstuffs. In the course of the development of the organic food market, it should be beneficial for manufacturers to target high-performance athletes and physically active people. PMID:28352693

    For decades tumors have been recognized as “wounds that do not heal.” Besides the commonalities that tumors and wounded tissues share, the process of wound healing also portrays similar characteristics with chronic fibrosis. In this review, we suggest a tight interrelationship, which is governed as a concurrence of cellular and microenvironmental reactivity among wound healing, chronic fibrosis, and cancer development/progression (i.e., the WHFC triad). It is clear that the same cell types, as well as soluble and matrix elements that drive wound healing (including regeneration) via distinct signaling pathways, also fuel chronic fibrosis and tumor progression. Hence, here we review the relationship between fibrosis and cancer through the lens of wound healing. PMID:24520152

    We investigate the weakly nonlinear evolution of a triad of nearly-neutral modes superimposed on a mixing layer with velocity profile u bar equals Um + tanh y. The perturbation consists of a plane wave and a pair of oblique waves each inclined at approximately 60 degrees to the mean flow direction. Because the evolution occurs on a relatively fast time scale, the critical layer dynamics dominate the process and the amplitude evolution of the oblique waves is governed by an integro-differential equation. The long-time solution of this equation predicts very rapid (exponential of an exponential) amplification and we discuss the pertinence of this result to vortex pairing phenomena in mixing layers.

    To characterize the clinical features, aetiology and management of ophthalmic symptoms in adult patients with Parinaud syndrome. This is a retrospective, non-comparative observational case series. We reviewed 40 consecutive charts of adult patients with the clinical diagnosis of Parinaud syndrome at the Royal Adelaide Hospital Department of Ophthalmology in Adelaide, South Australia, between 1991 and 2016. Charts were reviewed for the following: (1) demographic information, (2) clinical presentation, (3) neuro-ophthalmology signs, (4) aetiology of Parinaud syndrome, and (5) management. Examination findings were collected at initial evaluation, throughout the course of follow-up, and at last follow-up. All the cases were assessed by one of the authors (JLC). The commonest presenting symptoms were diplopia (67.5%) and blurred vision (25%) followed by visual field defect (12.5%), ataxia (7.5%) and manifest squint (7.5%). The commonest presenting signs were vertical gaze palsy (100%), convergence-retraction nystagmus (87.5%) and light-near dissociation (65.0%). Only 65.0% patients had the classical triad of vertical gaze palsy, convergence-retraction nystagmus and light-near dissociation. Midbrain pathologies including haemorrhage (30.0%), infarction (20.0%) and tumour (15.0%) were the commonest aetiology. Pineal region tumours accounted for 30.0% of presentations. Symptoms were managed conservatively in 45% of cases with temporary occlusion, prisms or refractive correction, and observation in 42.5% of cases. Surgical intervention for refractory diplopia was required in 12.5% of cases, of which 80% reported symptom resolution following surgery. Our series highlights the variable clinical presentation of Parinaud syndrome. The classic triad of conjugate upgaze paralysis, convergence-retraction nystagmus and light-near dissociation was only present in 65% of cases. Pineal neoplasms remain an important aetiological consideration; however, primary midbrain pathology

    To determine the etiology of sudden cardiac arrest and death (SCA/D) in competitive athletes through a prospective national surveillance program. Sudden cardiac arrest and death cases in middle school, high school, college, and professional athletes were identified from July 2014 to June 2016 through traditional and social media searches, reporting to the National Center for Catastrophic Sports Injury Research, communication with state and national high school associations, review of the Parent Heart Watch database, and search of student-athlete deaths on the NCAA Resolutions List. Autopsy reports and medical records were reviewed by a multidisciplinary panel to determine the underlying cause. US competitive athletes with SCA/D. Etiology of SCA/D. A total of 179 cases of SCA/D were identified (74 arrests with survival, 105 deaths): average age 16.6 years (range 11-29), 149 (83.2%) men, 94 (52.5%) whites, and 54 (30.2%) African American. One hundred seventeen (65.4%) had an adjudicated diagnosis, including 83 deaths and 34 survivors. The most common etiologies included hypertrophic cardiomyopathy (19, 16.2%), coronary artery anomalies (16, 13.7%), idiopathic left ventricular hypertrophy/possible cardiomyopathy (13, 11.1%), autopsy-negative sudden unexplained death (8, 6.8%), Wolff-Parkinson-White (8, 6.8%), and long QT syndrome (7, 6.0%). Hypertrophic cardiomyopathy was more common in male basketball (23.3%), football (25%), and African American athletes (30.3%). An estimated 56.4% of cases would likely demonstrate abnormalities on an electrocardiogram. The etiology of SCA/D in competitive athletes involves a wide range of clinical disorders. More robust reporting mechanisms, standardized autopsy protocols, and accurate etiology data are needed to better inform prevention strategies.

    The relationship between injury and performance in young athletes is scarcely studied. The aim of this study was therefore to explore the association between injury prevalence and ranking position among adolescent elite athletes. One hundred and sixty-two male and female adolescent elite athletes (age range 15-19), competing in athletics (n = 59), cross-country skiing (n = 66), and orienteering (n = 37), were monitored weekly over 22-47 weeks using a web-based injury questionnaire. Ranking lists were collected. A significant (P = .003) difference was found in the seasonal substantial injury prevalence across the ranked athletes over the season, where the top-ranked (median 3.6%, 25-75th percentiles 0%-14.3%) and middle-ranked athletes (median 2.3%, 25-75th percentiles 0%-10.0%) had a lower substantial injury prevalence compared to the low-ranked athletes (median 11.3%, 25-75th percentiles 2.5%-27.1%), during both preseason (P = .002) and competitive season (P = .031). Athletes who improved their ranking position (51%, n = 51) reported a lower substantial injury prevalence (median 0%, 25-75th percentiles 0%-10.0%) compared to those who decreased (49%, n = 49) their ranking position (md 6.7%, 25-75th percentiles 0%-22.5%). In the top-ranked group, no athlete reported substantial injury more than 40% of all data collection time points compared to 9.6% (n = 5) in the middle-ranked, and 17.3% (n = 9) in the low-ranked group. Our results provide supporting evidence that substantial injuries, such as acute and overuse injuries leading to moderate or severe reductions in training or sports performance, influence ranking position in adolescent elite athletes. The findings are crucial to stakeholders involved in adolescent elite sports and support the value of designing effective preventive interventions for substantial injuries. © 2017 John Wiley & Sons A/S.

    Certified athletic trainers (ATs) are responsible for integrating relevant professionals into the rehabilitation team to assist with the holistic care of injured athletes. To explore National Collegiate Athletic Association Division I (DI) ATs' experience with sport psychology consultants (SPCs), willingness to encourage athletes to use SPCs for injury rehabilitation, and perceptions of the benefits of sport psychology services. Quantitative study. A Web-based survey was administered to a national sample of DI ATs. A total of 659 (341 men, 318 women) ATs completed the survey. Athletic trainers' experience with SPCs, willingness to encourage athletes to seek sport psychology services, and perceptions of the benefits of those services in injury-rehabilitation settings were self-reported using a rating scale that ranged from 1 (never or not at all) to 5 (definitely or extremely). Logistic regression revealed that the availability of SPCs, previous encouragement to athletes to seek sport psychology services, and previous positive interactions with SPCs predicted the ATs' willingness to encourage athletes to use these services (P < .0001). The services ATs rated the highest for injury rehabilitation were managing anxiety and emotion, improving coping techniques, and building confidence (ie, confidence in returning to sport and building confidence). Chi-square analyses indicated that female ATs' ratings of perceived benefits were higher (P ≤ .001) than those of male ATs, and the ratings of ATs who were likely to encourage the use of SPCs were higher (P ≤ .001) than those who were unlikely to encourage SPC service use. Athletic trainers in our study who had previous positive SPC experiences were most likely to use SPCs and their services during the injury-rehabilitation process. Possible implications are offered for how ATs interested in sport psychology services might call on SPCs to complement their work with injured athletes.

    Background The issue of the expectations of elite athletes, their coaches and non‐medically qualified athlete support staff of consultations with sports physicians has not been previously dealt with in the sports medicine literature. As fulfilment of expectations of the content of a consultation may influence patient's satisfaction and clinical outcome, it is important to assess the expectations of athletes and, most importantly, coaches. Objective To assess the expectations and beliefs about fatigue, particularly in relation to blood tests, of athletes, their coaches and support staff in the specific context of tiredness of <7 days' duration. Subjects 28 senior sports science or non‐medically qualified sports medicine staff, 22 elite coaches and 62 elite athletes from the Australian Institute of Sport were included in this study. Methods A single questionnaire. Results The expectation for a blood test at the initial consultation for short‐term fatigue was particularly high among athletes (81%) and coaches (91%). This expectation increased in athletes if their performance was worsening. All groups unanimously suggested that a blood test be performed in cases of more prolonged fatigue. Increase in total training load was perceived to be the most important cause of fatigue, but issues relating to sleep were also thought to be highly relevant. All groups suggested that blood tests provide some degree of reassurance, and all groups suggested that the most important blood tests that might be performed related to exclusion of iron deficiency, anaemia and infection. Conclusion Athletes and their coaches generally expect that blood tests will be performed even when fatigue has been present for <1 week. This is at odds with currently available evidence of the diagnostic utility of these tests. Despite the current evidence base, individual factors in the athletes, coaches and doctors need to be considered when deciding on whether such testing has to be performed
