Overhead throwing athletes are at high risk of the elbow ulnar collateral ligament (UCL) injury, and there is a need for clinical tools to objectively diagnose severity of injury and monitor recovery. Mechanical properties of ligaments can potentially be used as biomarkers of UCL health. The objectives of this study are to evaluate the reliability of shear wave ultrasound elastography (SWE) for quantifying UCL shear modulus in 16 healthy nonthrowing individuals and use this technique to evaluate the difference in UCL shear modulus between the injured and uninjured elbows in a baseball pitcher with UCL tear. In the reliability test, the UCL shear modulus of both elbows of each participant was evaluated by SWE for five trials. The same procedures were repeated on two different days. The intra-day and day-to-day reliabilities were determined by the five measurements on the first day and two averages on the two days, respectively. In the case study, each elbow of the baseball pitcher with UCL tear was tested for five trials, and the average was calculated. The intra-day (intraclass correlation coefficient (ICC) = 0.715, Cronbach's alpha = 0.926) and day-to-day (ICC = 0.948, Cronbach's alpha = 0.955) reliabilities were found to be good. There was no difference between both sides. In the case study, the UCL shear modulus of the injured elbow (186.45 kPa) was much lower than that of the uninjured elbow (879.59 kPa). This study shows that SWE could be a reliable tool for quantifying the mechanical properties and health status of the UCL.

The anterior band of the ulnar collateral ligament (UCL) is commonly subjected to repetitive stress in overhead-throwing athletes, causing high subfailure strain and change in mechanical properties of the ligament. Understanding the change in UCL mechanical properties after repetitive loading can help to evaluate the health status of UCL. The objective of this study was to evaluate changes in UCL shear modulus in overhead-throwing, Division I college-level athletes over the course of a competitive season using ultrasound shear wave elastography (SWE). The proposed protocol quantified changes in shear modulus of UCL in 17 baseball players at preseason and season-end time points as well as in five football quarterbacks at preseason, midseason, and season-end time points. The highest shear modulus values were obtained in the nondominant arm at preseason time points in both groups of athletes. The average UCL shear modulus at the season-end decreased by 39.35% and 37.96% compared to the preseason values in dominant and nondominant arms, respectively. This study shows that SWE could quantify changes in the shear modulus of the UCL after repetitive loading, suggesting that it could be a useful clinical tool for evaluating the risk of UCL injury. Further research on injured overhead-throwing athletes is warranted.

Introduction: The problem that is often experienced by young women is anemia. This anemia condition causes them to feel lethargic, dizzy, and a pale face. This situation causes them to be less eager to carry out activities and interfere with their learning concentration. Objective: This study aimed to determine the reliability test results of the questionnaire on the level of knowledge about anemia in adolescents. Methods: This study used a cross-sectional study method. This research was conducted on February 28, 2021. The study population was all adolescents in the Islamic Boarding School of Tahfizh Putri Alfirdaus Hidayatullah, Sekardangan, Sidoarjo. The sampling technique used was total sampling. The sample size of the study was 24 adolescents. This study used a modified questionnaire for adolescent knowledge about anemia (Zulaekah, 2007). The questionnaire used in this study only used 8 items from the original questionnaire. The data analysis carried out was Mean, Standard Deviation, and Cronbach's Alpha. Results: Based on the results of the reliability test on the adolescent knowledge level questionnaire, it was found that Cronbach's Alpha was .594. This illustrates that the questionnaire is good enough to be used as an instrument in research. Conclusion: A modified questionnaire about the level of adolescent knowledge about anemia can be used in a study.

This study identified the readiness factors that may create challenges in the use of telemedicine among patients in northern Louisiana with cancer. To identify these readiness factors, the team of investigators developed 19 survey questions that were provided to the patients or to their caregivers. The team collected responses from 147 respondents from rural and urban residential backgrounds. These responses were used to identify the individuals’ readiness for utilising telemedicine through factor analysis, Cronbach’s alpha reliability test, analysis of variance and ordinary least squares regression. The analysis results indicated that the favourable factor (positive readiness item) had a mean value of 3.47, whereas the unfavourable factor (negative readiness item) had a mean value of 2.76. Cronbach’s alpha reliability test provided an alpha value of 0.79. Overall, our study indicated a positive attitude towards the use of telemedicine in northern Louisiana.

Tears of the ulnar collateral ligament (UCL) of the elbow are common injuries in overhead athletes. Although surgical reconstruction of the UCL has improved outcomes, not all athletes return to their previous level of competition and when this goal is achieved, the time required averages one to two years. Therefore, additional techniques are needed to further improve return to play and the rate of return to play in overhead athletes. A construct comprising a dermal allograft, platelet rich plasma (PRP), and mesenchymal stem cells (MSCs) has been shown to successfully improve healing in the rotator cuff. Given the promising provisional findings, we postulated that this construct could also improve healing if applied to the UCL. Therefore, the purpose of the present report was to examine the feasibility of utilizing a dermal allograft, PRP, and MSC construct to augment UCL reconstruction in a professional baseball pitcher. No complications were encountered. Although limited to minimal follow-up, the patient has demonstrated excellent progress and has returned to activity.

Introduction: St. George’s Respiratory Questionnaire (SGRQ) is a measuring tool to assess the quality of life of people with chronic obstructive pulmonary disease or various respiratory disorders. This study aimed to assess whether The Indonesian version of SGRQ was valid and reliable for subjects with chronic obstructive pulmonary disease (COPD). Methods: The Indonesian version of SGRQ was analyzed using a correlation test between SGRQ and sixminute walk distance (6 MWD) for validity. The reliability test was done using the test re-test reliability test by Spearman’s rank correlation, and Cronbach’s alpha for internal consistency. Results: Twenty-two patients eligible COPD patients were included in this study. There is a correlation between SGRQ’s component and 6MWD on activity (r= 0.49), impact (r= -0.58) and total SGRQ (r=-0.56). The SGRQ re-measurement test shows a strong correlation on the symptom (r = 0.76), activity (r = 0.58), impact (r = 0.51), total (r=0.58) and Wilcoxon test result shows there were no significantdifferences among subscales except total value p = 0.049. High internal Cronbach’s alpha consistency was approximately 0.73 to 0.86. Conclusion: The Activities and Impacts of Indonesian version of SGRQ component provides a picture of the validity to functional capacity. The Indonesia version of SGRQ is also proven to have good repeatability with high internal consistency.
