Abstract Objective This study aimed to examine the relationship between developmental stages and concussions that resulted in amnesia as measured by ImPACT. Method Participants were selected from an archival de-identified sports medicine ImPACT database. The sample (N = 4,200) was primarily male (62.2%) student athletes with ages ranging from 10 to 25 years. Participants were divided into three groups: Young athletes (n = 1,400), Adolescent (n = 1,400), and Adult (n = 1,400). A One-Way ANOVA was conducted to determine the relationship between age group and prevalence of concussions resulting in anterograde or retrograde amnesia. Results The One-Way ANOVA revealed significant differences between age group and anterograde F(2,4197) = 107.449, p < .001 and retrograde amnesia F(2,4197) = 82.949, p < .001. Bonferroni pairwise comparison revealed the adolescent athlete group experienced more concussions that result in both anterograde and retrograde amnesia compared to young and adult athletes. There was no significant difference between young and adult athletes. Additionally, there is a significant difference regarding total games missed following concussion F(2,4197) = 117.723, p < .001, with adolescent athletes missing more games compared to young and adult athletes. Conclusions The findings of this study suggest adolescent athletes tend to experience more amnesia-related concussions compared to young and adult athletes. Additionally, adolescent athletes miss more games following these types of concussions. This study highlights the impact that certain types of concussions have on athletes across the developmental stages. Future research should analyze the cognitive effects of various types of concussions across the developmental stages.

Glycated haemoglobin (HbA1c) test indicates the blood glucose levels for the previous two to three months. Using HbA1c test may overcome many of the practical issues and prevent infections such as urinary tract infections (UTIs). The study aimed to evaluate the impact of glycemic control using HbA1c test to understand patient characteristics and UTIs prevalence. Glycemic control was evaluated by measuring HbA1c for a total of 208 diabetes patients who were regularly attending diabetes center in Al-Noor specialist hospital in Makkah.  The results showed that good and moderate glycemic controlled patients were 14.9% and 16.9% respectively while the poor glycemic patients were 68.3%. Among the good improved glycemic control, 83.9% were females, 48.4% were from age group (15-44y). Among the moderately improved glycemic control, 68.4% were females, 54.3% were from age group (45-64 y) with no significant difference. The total number of the patients with positive UTIs was 55 (26.4%) while the total number of patients with negative was UTIs 153 (73.6%). Among the positive UTIs, 76.3% were with poor glycemic control while only 12.3% and 11% were moderate and good improved glycemic control respectively. Among the negative UTIs, 65.3% were with poor glycemic control while only 19% and 15.7% were with moderate and good improved glycemic control respectively.  Prevalence of UTIs among diabetic patients was not significant (p > 0.05). It was concluded that HbA1c was useful monitoring tool for diabetes mellitus and may lead to improved outcomes. Using a HbA1c test may overcome many of the practical issues that affect the blood glucose tests.

In recent years, there has been an increasing number of investigations analyzing the effects of sex, performance level, and age on pacing in various running disciplines. However, little is known about the impact of those factors on pacing strategies in ultramarathon trail running. This study investigated the effects of age, sex, and performance level on pacing in the UTMB® (Ultra-trail du Mont Blanc) and aimed to verify previous findings obtained in the research on other running disciplines and other ultramarathon races. Data from the UTMB® from 2008 to 2019 for 13,829 race results (12,681 men and 1148 women) were analyzed. A general linear model (two-way analysis of variance (ANOVA)) was applied to identify a sex, age group, and interaction effect in pace average and pace variation. A univariate model (one-way ANOVA) was used to identify a sex effect for age, pace average, and pace variation for the fastest men and women. In our study, pace average and a steadier pace were positively correlated. Even pacing throughout the UTMB® correlated with faster finishing times. The average pace depended significantly on sex and age group. When considering the top five athletes in each age group, sex and age group also had significant effects on pace variation. The fastest women were older than the fastest men, and the fastest men were faster than the fastest women. Women had a higher pace variation than men. In male competitors, younger age may be advantageous for a successful finish of the UTMB®. Faster male runners seemed to be younger in ultramarathon trail running with large changes in altitude when compared to other distances and terrains.

ABSTRACT Introduction Soldiers are expected to deploy worldwide and must be medically ready in order to accomplish their mission. Soldiers unable to deploy for an extended period of time because of chronic pain or other conditions undergo an evaluation for medical retirement. A retrospective analysis of existing longitudinal data from an Interdisciplinary Pain Management Center (IPMC) was used to evaluate the temporal relationship between the time of initial duty restriction and referral for comprehensive pain care to being evaluated for medical retirement. Methods Patients were adults (>18 years old) and were cared for in an IPMC at least once between May 1, 2014 and February 28, 2018. A total of 1,764 patients were included in the final analysis. Logistic regression was used to evaluate the impact of duration between date of first duty restriction documentation and IPMC referral to the outcome variable of establishment of a permanent 3 (P3) profile. Results The duration between date of first duty restriction and IPMC referral showed a curvilinear relationship to probability of a P3 profile. According to our model, a longer duration before referral is associated with an increased probability of a subsequent P3 profile with the highest probability peaking at 19 months. The probability of P3 declines gradually for those who were referred later. Discussion This is the first time the relationship between time of initial duty restriction, referral to an IPMC, and subsequent P3 or higher profile has been tested. Future research is needed to examine medical conditions listed on the profile to see how they might contribute to the cause of referral to the IPMC. Conclusion A longer duration between initial duty restriction and referral to IPMC was associated with higher odds of subsequent P3 status for up to 19 months. Referral to an IPMC for comprehensive pain care early in the course of chronic pain conditions may reduce the likelihood of P3 profile and eventual medical retirement of soldiers.

Objective To explore the impact of appendectomy history on emergence of Parkinson’s disease (PD). Background Although there are several studies to investigate the relationship between appendectomy history and emergence of PD, the results are still controversial. Methods We performed a comprehensive electronic search of the literature (the Cochrane Library, PubMed, and the Web of Science) up to April 2020 to identify studies that had employed databases allowing comparison of emergence of PD between patients with and those without appendectomy history. To integrate the impact of appendectomy history on emergence of PD, a meta-analysis was performed using random-effects models to calculate the risk ratio (RR) and 95% confidence interval (CI) for the selected studies, and heterogeneity was analyzed using I2 statistics. Results Four studies involving a total of 6 080 710 patients were included in this meta-analysis. Among 1 470 613 patients with appendectomy history, 1845 (.13%) had emergences of PD during the observation period, whereas among 4 610 097 patients without appendectomy history, 6743 (.15%) had emergences of PD during the observation period. These results revealed that patients with appendectomy history and without appendectomy had almost the same emergence of PD (RR, 1.02; 95% CI, .87-1.20; P = .83; I2 = 87%). Conclusion This meta-analysis has demonstrated that there was no significant difference in emergence of PD between patients with and those without appendectomy history.

Background: Patients with myocardial infarction reportedly have different outcomes on discharge according to hospital characteristics. In the present study, we evaluated the differences between urban teaching hospitals (UTH) and non-teaching hospitals (NTH), discharged in 2012. We also investigated on the outcomes. Methods: Sample of 117,808 subjects diagnosed with myocardial infarction were extracted from a nationwide inpatient stay dataset using the International Classification Data, ICD 9 code 41000 in the United States, according to hospital location, size, and teaching status. Results: The analysis of the data showed that more whites were admitted to both teaching and non teaching hospitals with more males (~24%) admitted than their female counterparts. However, blacks were admitted more (~15%) in urban teaching hospitals than medium urban non teaching hospitals. Age difference was noted as well, while age group (60-79 years) were admitted more in UTH, inversely urban non-teaching hospitals admitted more older (80 years or older) age group. A significant difference (~28%) was observed in both hospital categories with UTH admitting more patients of $1.00 - $38,999.00 income group than other income categories. In addition, it was observed that patients with MI stayed more (~5%) for 14 or more days, and charged more especially for income group of $80,000 or above in UTH than NTH. No significant difference was found in the mortality rate for both hospital categories. Conclusion: The overall outcomes showed that the mortality rate between urban teaching and non-teaching hospitals were non significant, though the inpatients MI stayed longer and were charged more in UTH than NTH. The authors call for the study to be replicated with a higher level of statistical measures to ascertain the impact of the variables on the outcomes for a more validated result.

The Relationship

Organizational scholars concurred that positive workplace relationships with others can helps employee to gain from these relationships but, they lack insights into how or why this occurs. Moreover, the relationship dynamics focus on what the relationships provide without considering the how these relationships initiated, builds and maintains. To line of this, the current study aims to find the impact of mentoring functions (career, psychosocial, role modeling) and employee performance (career success, organization citizenship behavior, and job performance) via mediating effect of relational self-efficacy. For this purpose, the data were gathered from 310 branch banking employees of Pakistani conventional banks. PLS-SEM was used for data analysis. The results indicate that there is direct relationship between mentoring functions and employee’s performance. Moreover, the finding also shows that employee relational self-efficacy mediates the relationship between mentoring functions and employee performance. Theoretical and practical implications are discussed along with suggestions for future research.

Since the 1960s, Australian scientists have speculated on the impact of human arrival on fire regimes in Australia, and on the relationship of landscape fire to extinction of the Pleistocene megafauna of Australia. These speculations have produced a series of contrasting hypotheses that can now be tested using evidence collected over the past two decades. In the present paper, I summarise those hypotheses and review that evidence. The main conclusions of this are that (1) the effects of people on fire regimes in the Pleistocene were modest at the continental scale, and difficult to distinguish from climatic controls on fire, (2) the arrival of people triggered extinction of Australia’s megafauna, but fire had little or no role in the extinction of those animals, which was probably due primarily to hunting and (3) megafaunal extinction is likely to have caused a cascade of changes that included increased fire, but only in some environments. We do not yet understand what environmental factors controlled the strength and nature of cascading effects of megafaunal extinction. This is an important topic for future research.

Prior research focusing on the impact of individualistic orientations on the performance of cooperative behaviors has produced mixed results. Researchers have concluded that the self-focused orientation of individualists will lead them to be less cooperative than others. On the other hand, some scholars have argued that helping others is core to individualists’ self-concept and that competently assuming the role of help-giver is a source of intrinsic satisfaction. In this study, we test this proposition by examining individualistic orientations within employee help-seeking networks. Results from a sample of 107 employees within a regional medical center indicate that the level of individualism in helping-seeking networks is positively associated with help-seekers’ perceptions of support. Further, the results suggest that the relationship is stronger in dense networks. Implications of this work and directions for future research are discussed.

The paper discussed on the relationship between employer branding and employee engagement among employees in selected furniture retailers in Malaysia. This study also looks into the state of employees’ engagement and gender differences in their engagement towards their organization. Furniture retailing falls under the retail trade industry that contributed about RM35.7 billion to Malaysia GDP in 2017 with expected growth of 8.7 percent. However, the industry suffers an average yearly employee turnover rate of 13 percent. Amid this high turnover, the raising question is can popularity of employers’ branding can result in employee engagement leading to their retention in the organisation. 350 respondents were chosen randomly and 120 (30%) respondents had given feedback on the personally administered questionnaires. The result revealed that there is significant relationship between employer branding and employee engagement. The study also indicated that work challenging is the most important variable which led to drive the employee engagement. Consequently, there is significant difference between male and female in terms of engagement. Organisation, hence may consider leveraging employee engagement which may lead to retaining their employees. Future research may consider researchers to pursue a longitudinal method of research design across a variety of firm-sizes and industries that would be more significant in making generalizations.

Context:Underwater treadmill (UTM) exercise is being used with increased frequency for rehabilitation of injured athletes, yet there has been little research conducted on this modality.Objective:To determine the cardiorespiratory responses of UTM vs land treadmill (LTM) exercise, particularly with respect to the relationship between heart rate (HR) and oxygen consumption (VO2).Design and Setting:This quantitative original research took place in sports medicine and athletic training facilities at Wake Forest University.Participants:11 Wake Forest University student athletes (20.8 ± 0.6 y, 6 women and 5 men).Intervention:All participants completed the UTM and LTM exercise-testing protocols in random order. After 5 min of standing rest, both UTM and LTM protocols had 4 stages of increasing belt speed (2.3, 4.9, 7.3, and 9.6 km/h) followed by 3 exercise stages at 9.6 km/h with increasing water-jet resistance (30%, 40%, and 50% of jet capacity) or inclines (1%, 2%, and 4% grade).Main Outcome Measures:A Cosmed K4b2 device with Polar monitor was used to collect HR, ventilation (Ve), tidal volume (TV), breathing frequency (Bf), and VO2 every minute. Ratings of perceived exertion (RPE) were also obtained each minute.Results:There was no significant difference between UTM and LTM for VO2 at rest or during any stage of exercise except stage 3. Furthermore, there were no significant differences between UTM and LTM for HR, Ve, Bf, and RPE on any exercise stage. Linear regression of HR vs VO2, across all stages of exercise, indicates a similar relationship in these variables during UTM (r = .94, y = .269x − 10.86) and LTM (r = .95, y = .291x − 12.98).Conclusions:These data indicate that UTM and LTM exercise elicits similar cardiorespiratory responses and that HR can be used to guide appropriate exercise intensity for college athletes during UTM.
