Weight For Age

Abstract Objectives Youth in weight-classified combat sports may attempt to change body weight to gain performance advantage. Differences between weight-for-age percentiles (WAP) and performance in youth wrestlers remains unknown. The purpose of this retrospective study was to examine the differences in performance between wrestlers above and below the 50th WAP over a wrestling season. Methods Participants included 22 male wrestlers from a team in the Pennsylvania Elementary Wrestling League (8.8 ± 2.1 years of age, 2.3 ± 2.3 years of experience). Retrospective data included age, weight, years of experience, family history, and frequency of wins, losses and forfeits over a 3-month wrestling season. Average WAP were calculated using CDC growth charts and wrestlers were assigned to one of two groups <50 th WAP (n = 10) and >50 th WAP (n = 12). Wrestlers were also categorized into two groups in terms of experience (≤2 years, >2 years). Differences between the two groups in performance variables were examined using ANOVA. Results We observed a significant difference between <50th and >50th WAP groups in total forfeits (0.6 ± 1.0; 2.0 ± 1.5, respectively, P < 0.02). There was an interaction observed between WAP group and years of experience in number of total forfeits (P < 0.132) such that wrestlers with <2 years of experience and <50th WAP experienced fewer total forfeits (0.3 ± 0.8) than those >50th percentile (2.0 ± 1.4). Those with more experience in <50th WAP also had fewer forfeits compared to >50th WAP. A similar interaction was observed between WAP group and years of experience in number of total losses (P < 0.187). Wrestlers with <2 years of experience, and <50th WAP experienced more total losses (4.8 ± 1.5) than wrestlers >50th WAP (2.0 ± 1.4). Those with more experience and <50th WAP experienced fewer losses than those >50th WAP. Conclusions We observed a significant difference in forfeits between average WAP groups and an interaction between experience and WAP groups in losses and forfeits in this small sample. Further research is needed to provide insight into how WAP mayaffect performance in this population. Future research may include a larger population, and variables such as BMI-for-age, hydration status, nutrition, body composition and additional factors that affect both weight and performance.

Ctnnb1 Mutation

286 Background: Mutations in TP53 and CTNNB1 are common in early stage HCC resection samples. The frequency and prognostic impact of these mutations in advanced HCC is not known. We conducted this retrospective analysis using a large NGS panel to explore for association between tumor genetics, clinicopathologic features, and prognosis in an advanced HCC cohort. Methods: Eligible cases had diagnosis of unresectable HCC or mixed HCC-cholangiocarcinoma and were enrolled on NCT01008917 or NCT01687673 clinical trials of sorafenib plus temsirolimus with informed consent for specimen banking for future research including genetic testing. Paired tumor and germline (blood) DNA samples were sequenced using a capture-based NGS cancer panel to allow for determination of somatic variants. Analysis was based on the human reference sequence UCSC build hg19. Variants were called using GATK Unified Genotyper software. Somatic, non-synonymous, and exonic calls were curated using COSMIC, cBioPortal, and Pubmed. Results: Cases with HCC (n = 21) and mixed HCC-cholangiocarcinoma (n = 2) comprised the cohort (N = 23). Male/female: 83%/17%. Race: White 56%, Asian 39%. BCLC stage: B 35%, C 65%. Etiology: HBsAg+ 26%, HCV+ 39%. Immune infiltrates ( ≥ 1 on scale 0-3) were present in 7/12 (58%) evaluable tumor samples. TP53 mutations were present in 14/23 (61%, 95% CI: 38.5, 80.0). CTNNB1 mutations were present in 7/23 (30%, 95% CI: 13.2, 52.9). There was no significant difference between HBsAg+ and HCV+. Both TP53 and CTNNB1 mutation were present in 4/23 (17%). CTNNB1 mutation was present in 2/7 (29%) cases with immune infiltrate score ≥ 1, and 1/5 (20%) with score < 1 (not significant). Other mutations and variants will be reported. Conclusions: NGS in this advanced HCC cohort suggests a higher incidence of TP53 and coexisting TP53 plus CTNNB1 mutations than has been reported in early stage HCC which requires confirmation in a larger cohort. There was no clear relationship between these mutations, HCC etiology, or tumor immune infiltrates though interpretation is limited by small sample sizes. Analyses are ongoing to explore for association between TP53 and CTNNB1 mutations and prognosis in this advanced HCC cohort.

Nurses Knowledge

Context: Brachytherapy is one of the cancer treatment modalities. Like any treatment, it can produce acute and delayed side effects. Unfortunately, patients getting brachytherapy experience many side effects that may affect their all quality of life aspect. So, nurses working in radiotherapy settings must be confident about their knowledge, competence, and technical skills. Therefore, holding continuing education programs for nurses is necessary.  Aim: This study aimed to determine the effect of brachytherapy safety education on radiology nurses' knowledge, attitude, and performance. Methods: Quasi-experimental one group pre-posttest design was utilized to achieve the aim of this study on nurses working on Ayadi El Mostakabal Hospital, Alexandria, Egypt. Four tools were used to collect the necessary data. The self-administered questionnaire was designed to collect the necessary data about the nurses. Radiology Nurses’ Knowledge Assessment Questionnaire to assess nurses' knowledge regarding nursing interventions for patients getting brachytherapy. Nurses’ Performance Observational Checklist to assess the actual nurses’ performance provided to patients getting brachytherapy. Radiology Nurses' Attitude Assessment Scale (RNAAS) measures nurses' professional attitude and the influence of safety training programs on nurses' attitudes. Results: There was a statistically significant difference between nurses' knowledge, performance, and attitude between the initial assessment, immediate, two weeks later, and three months of educational program implementation at p=0.001. Regarding the relationship between studied nurse's knowledge and their characteristics, there was a relationship found between nurses’ knowledge in the initial assessment and their age, marital status, and nurses’ years of experience at p=0.001, 0.002, and 0.0, respectively. While in the post-program implementation, the only relation was found between the nurses’ knowledge score and years of experience p=0.007, 0.053, and0.011 in immediate, two weeks later, and after three months of program implementation, respectively. There was no relation found between nurses' performance and their characteristics throughout program implementation phases. Conclusion: The current study findings concluded that radiation safety education for nurses regarding brachytherapy resulted in a statistically significant improvement in nurses' knowledge, performance, and attitude. Periodic and consistent update in-services training of nurses to improve their knowledge and practice enforces nurses to follow the approved guideline. Future studies are recommended to investigate nurses' knowledge and performance of radiation protection in the general ward or specialized departments.

The Impact

AbstractThe ability to effectively cope with stress has been demonstrated to be an important factor in warding off potential physical disease and psychological distress. Responses to stressful events have been shown to greatly vary across individuals. Research has shown that intervening variables, such as cognitive appraisals of stressful events, can markedly affect the amount of stress (e.g., mood disturbance, anxiety, changes in neurotransmitter concentrations, suppression of immune system functioning) individuals experience. One such intervening variable, productive humor, was hypothesized to have a positive stress-moderating effect.Four different experimental conditions were used to assess the impact of a stressful situation on mood and anxiety state. Two conditions had subjects produce a humorous narrative in response to the stressful situation. One of these conditions included an instructional video on the use of productive humor. A third condition had subjects produce an intellectual narrative, while a fourth condition had subjects produce no narrative. The humorous narrative conditions were hypothesized to lead to the greatest moderation in stress (i.e., mood and anxiety).In the humorous narrative (without training) condition, subjects who were more successful at producing the narratives showed significantly more moderated changes in mood and anxiety levels pre-task to post-task. These changes were not significantly different from the intellectual or no narrative conditions. The significant difference found between high versus low humorous narrative producers may be accounted for in terms of success versus non-success at completing the experimental task.Finally, among subjects with initially high pre-task mood or anxiety levels and high tendencies to use productive humor, successful performance of some type of a verbal, cognitive task (i.e., humorous or intellectual narrative) was found to be more beneficial in moderating the effects of stress versus silence. These latter findings were based on patterns of results from post hoc analyses with small sample sizes, thus suggesting the need for future research along similar lines.

Practice Time

High school singers ( N=198) individually sang two melodies from notation, with and without a 30-second practice opportunity. Overall accuracy scores were significantly higher with preparation time. The less accurate singers, however, did not benefit from practice time. Analysis of videoed tests indicated that high scorers tonicized (vocally established the key), used hand signs, sang out loud during practice, physically kept the beat, and finished practicing the melody within 30 seconds significantly more frequently than did low scorers during practice. Similar strategies were used during performance, with the addition of tonicizing before singing. Sight-singing system used made no significant difference. Characteristics appearing significantly more often among high scorers included: region/state choir, private voice or piano lessons, playing an instrument, membership in instrumental ensemble, sight-singing individually outside class, and director giving individual sight-singing tests. Results are discussed in terms of strategies for teaching individual sight-singing and recommended areas of future research. August 11, 2004 January 18, 2005.

AbstractAdvances in biomedicine and other fields of science and technology depend on research teams and their peer-reviewed publications. The scientific literature represents an invaluable socioeconomic resource guiding future research. Typically, this growing body of information is explored by queries in bibliographic databases concerning topics of interest and by subsequent scrutiny of matching publications. This approach informs readily about content, but leaves the workforce driving the field largely unexplored. The hurdle can be overcome by a transparent team-centered analysis that visualizes the teams working in a field of interest and that delineates their genealogic and collaborative relations. Context-specific, but citation-independent metrics gauge team impact and reveal key contributors valuing publication output, mentorship and collaboration. The new insight into the structure, dynamics and performance of the workforce driving research in distinct disciplines complements ongoing efforts to mine the scientific literature, foster collaboration, evaluate research and guide future policies and investments.

Insight Into

The findings of the research into the perceived parental behavior provide contrasting data as to the existence and the nature of differences in the perception of parental behavior based on parents? gender and respondents? gender. The purpose of the present study is to examine the differences in the perceived parental behavior in adolescents with regard to parents? gender and respondents? age and gender. The study included 466 respondents (262 girls and 204 boys), in middle to late adolescence, divided into four sub-groups according to their age. The respondents were asked to fill in the Parental Bonding Instrument (PBI) questionnaire which measures the care and overprotection in mothers and fathers respectively. The obtained findings show the existence of significant difference based on the parents? gender for both subscales: both maternal care and maternal overprotection were estimated as higher. Observing the differences by respondents? gender on the whole sample, only one significant difference is found: paternal overprotection was estimated as higher by girls. The differences by age as observed within gender groups are completely disparate for girl and boy groups. The best insight into the differences is obtained through analysis by gender, for groups relatively homogenous in terms of their age (for the first three groups the only significant difference appears in the paternal overprotection subscale; the difference disappears in the subgroup of the oldest respondents?, while the differences between the perception of maternal and paternal care are of significance here). One particularly important finding for future research into rearing behavior is the fact that the perception of parental behavior changes over the period of adolescence differently for boys and girls; therefore, the analysis including perceived parental behavior should be performed for subgroups by gender, which are as homogenous as possible in terms of their age.

People With Intellectual Disabilities

The attitudes of education and rehabilitation students towards people with intellectual disabilities are very important, because they aim to be future professionals who will provide educational and rehabilitation treatment to these people, as well as advocates for their rights and needs. This study aimed to analyse the attitudes of students towards people with intellectual disabilities and to determine whether their attitudes differed based on self assessments and sources of knowledge about intellectual disabilities, ways of getting to know a person with intellectual disabilities, and number of years of education. The study involved 100 students undergoing their first cycle of studies at the Faculty for Special Education and Rehabilitation, University of Tuzla. The Mental Retardation Attitude Inventory-Revised (MRAI-R) and a general questionnaire were used in this study. The results show that students express positive attitudes towards people with intellectual disabilities, they are positive about educational integration of these people, and respect their rights. They do not express to need to socially distance from them and do not attribute unfavourable characteristics to these people. There were no differences in attitudes based on self-assessments of knowledge and the sources of knowledge about intellectual disabilities, or the way in which they got to know a person with intellectual disabilities. There was a significant difference in attitudes based on the number of years of education: fourth-year students were observed to express the highest degree of positive attitudes towards people with intellectual disabilities globally and towards the integration of these people in society, and they expressed the lowest level of social distance. Given the small sample of research subjects, as well as the fact that the study involved students of one education and rehabilitation faculty. in Bosnia and Herzegovina, the results obtained and the conclusions derived from them should be considered with caution. Future research should include a larger sample of education and rehabilitation students to verify the results obtained in this study.

To examine how the level of humility expressed through athletes’ social media postings and post volume is associated with the athletes’ in-game performance, the authors collected National Football League players’ social media activities throughout one season, in addition to player performance and profile information. To account for the multilevel and panel structure of the data, they conducted a series of fixed-effects panel models. In addition to a negative relationship between social media posting frequency and performance, the authors found that players who post social media content with a higher level of humility are more likely to have better performances. However, this humility–performance association follows an inverted U-shaped relationship. The results provide insight into how critical athletes’ social media activity is for in-game performance. This study also provides important implications for athletes, team coaches, staff, and managers and provides guidance for future research.

Background: Latissimus dorsi and teres major (LD/TM) tears are becoming an increasing common cause of injury and disability amongst professional baseball pitchers. Purpose: To determine the rate of return to sport (RTS) and performance upon RTS in professional baseball pitchers following LD/TM tears treated both operatively and non-operatively, and to see if there is a difference in RTS rate and performance between players who sustained a LD/TM tear and matched controls within each treatment group. Hypothesis: There is a high rate of RTS in professional baseball pitchers following LD/TM tears with no significant difference in rate of RTS or performance, specifically related to the primary outcome performance variables of earned run average (ERA), WHIP ((walks +hits)/innings pitched), fielding independent pitching (FIP), and wins above replacement (WAR)) between cases and controls for both operative and non-operative treatment. Methods: All professional baseball pitchers who sustained a LD/TM tear between 2011-2016 were included. Demographic and performance data (pre and post injury) for each player was recorded. Performance metrics were then compared between cases and matched controls within both operatively non-operative treatment. Results: Overall 120 pitchers sustained a LD/TM tear; 42 (35%) were playing at the major league level at the time of injury. The majority of players (107 (89.2%)) were treated non-operatively. The average time to return to the same level of competition for pitchers treated non-operatively was 170.7 +/- 169.7 days while for those treated operatively was 536.6 +/- 300.4 days. Of the players treated with surgery, the mean time from injury to surgery was 97.5+/-115.5 days (range 12-453 days). The RTS rate among players treated non-operatively and operatively was identical at 75%. Players treated non-operatively had no change in ERA, FIP, or WAR following injury but had a higher WHIP after injury (p=0.039). Players treated operatively had no change in any measured performance metrics following surgery. No difference existed between cases and controls in the primary performance variables Conclusion: LD/TM tears occur more frequently than previously reported. The majority of LD/TM tears in professional baseball pitchers are treated non-operatively. RTS rate for professional baseball pitchers following LD/TM tears treated operatively or non-operatively is 75%. No significant difference in performance was seen in these pitchers following tear/surgery compared to matched controls.

Insight Into

Camps may be beneficial environments to provide military families with opportunities to participate in meaningful leisure to revitalize family relationships and to form connections within the military family community. While research has investigated the effects of these programs on veterans and families, limited research incorporates consumer-based evaluations of the service provider. Thus, the purpose of this study was to perform an evaluation of a therapeutic, recreation-based military family camp. A multiphase importance performance analysis (IPA) was implemented with 19 individuals who attended the camp. Participants rated program components using a 5-point Likert scale. Results revealed high importance and performance scores on all program components, as well as highlighted areas of programing with opportunity for maintenance and improvement. These findings provide recommendations for the improvement of this camp, as well as insight into future research and/or evaluations of military family camp programing.
