Tactical skill in Australian youth soccer: Does it discriminate age-match skill levels?

Objectives Football Federation Australia (FFA) has identified that Australian athletes are proficient physically, however often lack the technical and tactical skills to excel internationally. The aim of the current study was to assess if a video-based decision-making test could discriminate different age-matched skill levels of talent in Australian soccer. Design Cross-sectional observational. Methods Sixty-two youth male soccer players completed a video-based decision-making test. Results An ANOVA test showed that the video-based test significantly discriminated between all three groups, with the national elite athletes selecting more correct responses than the state elite (65.3 ± 8.1%; 56.0 ± 9.1%, respectively). The state elite were more accurate than the sub-elite (45.9 ± 8.8%). Conclusions Results suggest that a video-based test may be a suitable tool to use in the selection of athletes as a measure of decision-making skill. The low accuracy scores, even for the national elite cohort, suggest that decision-making skill at the youth level has room for improvement and should be prioritised as an area for development.

Physical and anthropometrical attributes of Australian youth soccer players

Objectives To determine whether Australian youth soccer players of varying levels could be distinguished based on their anthropometrical and physical attributes. Design A cross-sectional observational design was used, involving six anthropometrical and physical tests for each player. Methods Participants represented three youth levels of competition, namely national elite (n = 18), state elite (n = 22) and sub-elite (n = 22). Anthropometrical and physical tests included standing height; body mass; 5, 10, 30 m sprint and 20 m ‘flying start’ sprint; zig-zag agility test; vertical jump and Yo-Yo Intermittent Recovery test level 1. A multiple analysis of variance for the main effect of cohort, with a follow-up ANOVA and Tukey's Honest Significant Difference were used to discern which attributes differed between each cohort. Receiver operating characteristic curves were calculated, providing cut-off values between cohorts. Results The national elite cohort was significantly taller than the state elite cohort (ES = 0.94) and faster than the sub-elite athletes across 30 m (ES = 0.79) and 20 m with a flying start (ES = 0.77) (P < 0.05). The national elite cohort had a significantly higher level of intermittent endurance, compared to the state elite athletes who also performed better than the sub-elite cohort. The discrepancy between groups in the Yo-Yo Intermittent Recovery test level 1 was exemplified by the receiver operating characteristic with 94.1% of national elite players running further than 1980 m, while 95.7% of state elite and 100% of sub-elite players failed to reach this distance (ES = 0.88–1.77). Conclusions It is evident that anthropometrical and physical attributes differ between youth cohorts, particularly intermittent endurance. It is important to use this knowledge to enhance the current processes used to identify future talent for success in Australian soccer.

Biomedical Science Undergraduate Major: A New Pathway to Advance Research and the Health Professions

ABSTRACTProblem: Many students entering professional degree programs, particularly M.D., Ph.D., and M.D./Ph.D., are not well prepared regarding the breadth of scientific knowledge required, communication skills, research experience, reading and understanding the scientific literature, and significant shadowing (for M.D.-related professions). In addition, physician scientists are a needed and necessary part of the academic research environment but are dwindling in numbers. Intervention: In response to predictions of critical shortages of clinician investigators and the lack of proper preparation as undergraduates for these professions, the Biomedical Science (BMS) undergraduate major was created at The Ohio State University to attract incoming college freshmen with interests in scientific research and the healthcare professions. The intent of this major was to graduate an elite cohort of highly talented individuals who would pursue careers in the healthcare professions, biomedical research, or both. Context: Students were admitted to the BMS major through an application and interview process. Admitted cohorts were small, comprising 22 to 26 students, and received a high degree of individualized professional academic advising and mentoring. The curriculum included a minimum of 4 semesters (or 2 years) of supervised research experience designed to enable students to gain skills in clinical and basic science investigation. In addition to covering the prerequisites for medicine and advanced degrees in health professions, the integrated BMS coursework emphasized research literacy as well as skills related to work as a healthcare professional, with additional emphasis on independent learning, teamwork to solve complex problems, and both oral and written communication skills. Supported by Ohio State's Department of Internal Medicine, a unique clinical internship provided selected students with insights into potential careers as physician scientists. Outcome: In this educational case report, we describe the BMS undergraduate major and its outcomes after 10 years of implementation. Major outcomes include the strength of the major's matriculates (average ACT score = 32.6; average high school class percentile rank = 95.5) and the high percentage of BMS students who pursued graduate/professional degrees (91%; n = 110). Other markers of success include the strong focus on research, which resulted in 120 articles published by graduates to date (range = 0–12/student; 43% with at least 1 peer-reviewed journal article). Lessons Learned: Based on its successes, adoption of a similar program at other academic medical centers would help feed the pipeline of well-trained health professionals and biomedical researchers.

Maximizing Respiratory Health In Elite Swimmers - A Systematic Approach To Optimize Total Airway Health

Elite Swimmers are known to have high prevalence of exercise induced bronchoconstriction (EIB), nasal and sinus disorders. There is however limited data available regarding the impact of a systematic assessment, addressing all aspects of airway health in this cohort. PURPOSE: To report the findings of a systematic approach to evaluating total airway health in elite swimmers with EIB, prior to the 2016 Olympics. METHODS: 15 elite swimmers (9 males, 6 females), age 22.2 ± 2.9 yrs underwent a systematic assessment of total airway health three months prior to the Olympics. All swimmers had a prior diagnosis of EIB, confirmed by indirect bronchoprovocation challenge and measurement of exhaled nitric oxide (FeNO). All were prescribed appropriate inhaler therapy and educated on inhaler technique. At the systematic assessment spirometry, FeNO, inhaler flow-rate, nasal flow was measured and they also underwent an assessment with a pulmonologist. Results were analysed using paired t-tests and are presented as mean ± SD. RESULTS: All swimmers had at least one co-existing condition in addition to EIB including nasal disease, reflux, sensations of laryngeal closure, recurrent respiratory tract infection and abnormal breathing sensations. One-third reported side effects from inhaler use. All swimmers demonstrated sub-optimal inhaler technique based on an inhalation rate of 348 ± 49.4 L.min-1. Despite being prescribed treatment for EIB, three swimmers had on-going airflow obstruction with bronchodilator reversibility of FEV1 by 12.9 ± 7.7 % above baseline. At the review FeNO was reduced (pre: 27.7 ± 15.1, post: 16.3 ± 6.5 ppb (p = 0.006) from first consult. CONCLUSION: Despite being prescribed EIB treatment over half of an elite cohort of swimmers reported troublesome respiratory and allied symptoms. Moreover, inhaler technique was sub-optimal with frequent report of side-effects. Respiratory health in elite swimmers can be optimized through systematic assessment of airway health.

Technical attributes of Australian youth soccer players: Implications for talent identification

Objectives To determine whether the technical ability of Australian youth soccer players could distinguish between various playing levels. Design A cross-sectional observational design was used with each player required to complete four technical tests. Methods Sixty-two participants were representatives of three cohorts of youth soccer in Australia: national elite ( n = 18), state elite ( n = 22) and sub-elite ( n = 22). The technical tests used were Loughborough Short Passing Test (LSPT), long passing test (LPT), shooting test and speed dribbling, with all players familiarised with the tests prior to data collection. Differences between cohorts were analysed using a multiple analysis of variance test with follow-up analyses of variance and Tukey Honest Significant Difference post-hoc test, which were subsequently used to inform a sensitivity analysis, more specifically a bootstrapped receiver operating curve to determine cut-off scores for each variable. Results The national elite cohort scored better than state- and sub-elite cohorts on the LSPT, however, the state elite produced the fastest time before penalties. The sub-elite cohort scored less points on the LPT compared to both national- and state-elite cohorts, on both feet. In regards to speed dribbling, national-elite players were faster than both the state- and sub-elite cohorts. Shooting accuracy and velocity were able to discriminate the national- and sub-elite cohorts on the dominant foot, with shooting velocity on the nondominant foot being faster for the national elite compared to both the state- and sub-elite cohorts. Conclusions A number of differences in technical ability were identified between varying levels of Australian youth soccer players. Youth soccer coaches and sports scientists should use the cut-off scores for the technical tests in the talent identification and development process, with aspiring players aiming to reach these levels.

Polish Graduates and British Citizenship: Amplification of the Potential Mobility Dynamics beyond Europe

In light of the EU enlargements and a promise of unrestricted mobility within EU borders for European nationals, the opportunity was rapidly taken up in particular by young and highly educated Poles. However, some aspirant migrants wished to travel beyond EU borders and such individuals sought different strategies to migrate, including obtaining British citizenship and passports. The paper highlights the possibility of a go-stop-go mobility, which can be described as a stepped approach to citizenship, and a key feature of the new elite cohort of young European graduates, who use their European citizenship to obtain an alternative citizenship that acts as a passport literally and metaphorically to mobility beyond Europe.

Indocyanine Green SPY Elite–Assisted Sentinel Lymph Node Biopsy in Cutaneous Melanoma

Sentinel lymph node biopsy is the standard of care for intermediate-depth and high-risk thin melanomas. Recently, indocyanine green and near-infrared imaging have been used to aid in sentinel node biopsy. The present study aimed to determine the feasibility of sentinel lymph node biopsy with indocyanine green SPY Elite navigation and to critically evaluate the technique compared with the standard modalities. A retrospective review of 90 consecutive cutaneous melanoma patients who underwent sentinel lymph node biopsy was performed. Two cohorts were formed: group A, which had sentinel lymph node biopsy performed with blue dye and radioisotope; and group B, which had sentinel lymph node biopsy performed with radioisotope and indocyanine green SPY Elite navigation. The cohorts were compared to assess for differences in localization rates, sensitivity and specificity of sentinel node identification, and length of surgery. The sentinel lymph node localization rate was 79.4 percent using the blue dye method, 98.0 percent using the indocyanine green fluorescence method, and 97.8 percent using the radioisotope/handheld gamma probe method. Indocyanine green fluorescence detected more sentinel lymph nodes than the vital dye method alone (p = 0.020). A trend toward a reduction in length of surgery was noted in the SPY Elite cohort. Sentinel lymph node mapping and localization in cutaneous melanoma with the indocyanine green SPY Elite navigation system is technically feasible and may offer several advantages over current modalities, including higher sensitivity and specificity, decreased number of lymph nodes sampled, decreased operative time, and potentially lower false-negative rates.

Careers of an elite cohort of U.S. basic life science postdoctoral fellows and the influence of their mentor's citation record

BackgroundThere is general agreement that the number of U.S. science PhDs being trained far exceeds the number of future academic positions. One suggested approach to this problem is to significantly reduce the number of PhD positions. A counter argument is that students are aware of the limited academic positions but have chosen a PhD track because it opens other, non-academic, opportunities. The latter view requires that students have objective information about what careers options will be available for them.MethodsThe scientific careers of the 1992-94 cohort of NIH National Institute of General Medical Sciences (NIGMS) Kirchstein-NRSA F32 postdoctoral fellows (PD) was determined by following their publications (PubMed), grants (NIH and NSF), and faculty and industry positions through 2009. These basic life science PDs receive support through individual grant applications and represent the most successful class of NIH PDs as judged by academic careers and grants. The sex dependence of the career and grant success and the influence of the PD mentor's citation record were also determinedResultsOf the 439 1992-94 NIGMS F32 fellows, the careers of 417 could be determined. Although females had significantly higher rates of dropping out of science (22% females, 9% males) there was no significant difference in the fraction of females that ended up as associate or full professors at research universities (22.8% females, 29.1% for males). More males then females ended up in industry (34% males, 22% females). Although there was no significant correlation between male grant success and their mentor's publication record (h index, citations, publications), there was a significant correlation for females. Females whose mentor's h index was in the top quartile were nearly 3 times as likely to receive a major grant as those whose mentors were in the bottom quartile (38.7% versus 13.3%).ConclusionsSixteen years after starting their PD, only 9% of males had dropped out of science. More females (28%) have dropped out of science, primarily because fewer went into industry positions. The mentor's publication record does not affect the future grant success of males but it has a dramatic effect on female grant success.

Pie-eyed Optimists: Baby-boomers the Optimistic Generation?

Social indicators research is concerned with the measurement of quality of life in society from both the objective and subjective point of view. The subjective appraisal of quality of life often involves judgements in terms of “satisfaction” (Veenhoven, 1996: 1). Such research however, is not only concerned with satisfaction but also with dissatisfaction. The concepts of pessimism and optimism are used in this paper to determine feelings of satisfaction and dissatisfaction among an elite cohort of baby boom Australians. Objective and subjective potential indicators of quality of life are combined to explore these dimensions.

A Brief History of Pediatric Nurse Practitioners and NAPNAP 1964–1990

The pediatric nurse practitioner movement began in 1964 and is now 25 years old. Anniversaries are a good time for pausing to look backward and look forward. This brief history reports some early pediatric nurse practitioner adventures and a few of the beginning episodes of the National Association of Pediatric Nurse Associates and Practitioners. These special highlights make a remarkable statement about an elite cohort of nurses.

Diseases of the Liver,

Editor Leon Schiff and his elite cohort of 42 contributors have created another superb, exhaustive survey of contemporary hepatology. Delicately I took Sheila Sherlock's recent (1968) version of Diseases of the Liver from the shelf and opened the fragile, prematurely aging tome to compare sections. The British offering has unmistakable charm along with breadth and the steadiness that comes with solitary authorship by a scholarly clinicianinvestigator. But it is a Model T on a fast track with a Sting Ray; Schiff's opus wins all the blue ribbons. For example, his chapter on electron microscopy (by Schaffer and Popper—who else?) covers 33 pages, includes 16 electron photomicrographs and lists 181 references. Sherlock devotes 31/2 pages, 2 electron photomicrographs and 32 references (mostly concerned with other aspects of liver anatomy). This is fairly typical. Moreover, Schiff has been judicious in recruiting his all-star cadre of co-authors: Rapoport on anatomy, Ratnoff on coagulation
