<p>This study aimed to demonstrate the effect of successive stages of high-level judo competitions on match outcome and the factors effecting it. A total of 4550 official matches in both men and women were included in the analysis. Frequencies and percentages were used for descriptive statistics. Mean and standard deviations with 95% confidence intervals were also presented. The difference in the variables investigated for each stage of judo competitions was analysed with the Chi-square test. Continuous variables were analysed with the Kruskal-Wallis test. The way competitors won a match differed in elimination, final stages, and medal matches (<em>p</em>=.02). When the difficulty of the matches increased, the percentage of the matches ended with <em>ippon </em>decreased and the percentage of the matches resulted with <em>waza-ari</em> increased. The percentage of the matches without any <em>shido</em> decreased from the elimination to the finals while there was a significant increase in the percentage of the matches with s<em>hido </em>(<em>p</em>=.01). The match duration was found to increase from eliminations to the finals (<em>p</em>=.00). The efficiency index of the winner athletes during the first stage was higher than the other stages (<em>p</em>&lt;.05). In conclusion, high-level judo athletes won a match with different scores at different stages during high-level judo competitions. Moreover, athletes were awarded with penalties more during the finals compared to eliminations, and match duration incrementally increased from the eliminations to the finals.</p>

The Impact

Purpose: International Judo Federation introduced a set of new rules in a short time period (2009 − 2013). The aim of this research is to determine how the rule modification influences the gripping configurations used by elite male judo athletes. Methods: The sample contained 280 combats from the 2011 and 2014 World Championships. All the effective and ineffective throw attempts with related gripping configurations were registered. The Chi-square test was used to determine the difference between frequencies, along with Z-test for calculating the partial difference. Results: A total of 1707 actions and gripping configurations were registered. The Chi-square test showed that there is a significant difference in the usage of gripping configurations between the two championships (χ2=32,8; sig<0,001). The Z-test showed a significant increase in the usage of kenka-yotsu and ai-yotsu, and a significant decrease in the usage of central grip, cross grip and situations where only tori has established a grip. The difference in the usage of the same side grip was not detected. Conclusion: The recommendation for coaches is to reduce the use of all other gripping configurations except kenka-yotsu and ai-yotsu when practicing techniques, especially unorthodox gripping like the cross grip and the same side grip.

Abstract: The utilization of hospital services is a benchmark for the success of a health care referral system. Indonesia as the largest archipelago in the world encounters challenging conditions along with lack of infrastructure posed economic and health disparity among its regions. Disparities as a result of this development also have an impact on the accessibility of health care facilities. Regions with good economic movements tend to have good accessibility to health care facilities. For this reason, reducing disparity to achieve universal health services is the goal of health planners and policy makers. Chi Square test was used to test dichotomy variables and t-tests was performed for analysing the difference among continuous variables. These tests were employed to assess the hypothesis that there was significant regional difference in the access of health care in Indonesia. Estimation using multinomial logistic regression test was used to study the disparity between regions in hospital utilization. The results of this study showed that disparities between regions in Indonesia exist in term of hospital utilization. The disparities in hospital utilization among regions in Indonesia were associated with: marital status, socioeconomic status, education level, occupation and insurance ownership. However, the difference in odds ratio for mortality between regions decreased compared to the previous period. Conclusion. Disparities in the hospital utilization among region in Indonesia was associated with complex factors from individual characteristics through geographic barriers.

415 Background: It has been argued that universal screening for LS should be performed on all patients (pts) diagnosed with CRC because screening LS pts and their relatives can detect early cancers and improve outcomes. This approach is being adopted by many comprehensive cancer centers around the country. The Ohio State University (OSU) began screening for deficient mismatch repair (dMMR) proteins by immunohistochemistry (IHC) on all CRC cases in 2006. This retrospective study aims to assess whether universal screening with IHC followed by conclusive testing (BRAF mutation in setting of MLH1 deficiency, and/or gene sequencing) affects pts survival. Methods: All CRC pts diagnosed at OSU from 3/2006-6/2012 with dMMR testing per IHC were included, and their charts were reviewed. Chi-square test was used to for categorical parameters, t-test was used for continuous variables, and the log-rank test for overall survival (OS) to compare the difference between pts with full conclusive testing vs those without full testing. Patients who expired within 4 weeks of diagnosis were excluded (n=10) from the OS analysis. Results: One hundred and twenty-two tumors (15.7% of 777 tumors tested) had dMMR by IHC during the study period. Fifty-one pts went on to have conclusive testing done; thirteen patients (25.5%) were diagnosed with LS, 29 patients (56.9%) had MLH1-hypermethylated tumors, and 9 patients (17.6%) were not found to have MMR mutations on gene sequencing. In an OS analysis, patients undergoing conclusive testing had significantly longer survival as compared to those with abnormal IHC without further testing (median OS not reached vs. 38 months, p=0.04). The difference was similar and remained marginally significant (p= 0.04-0.09) after correcting for age, stage and testing date using different models. Conclusions: Patients who had conclusive testing after initial abnormal universal screening with IHC had significantly longer OS compared to pts who had abnormal IHC without follow-up testing. It is possible that ascertainment bias and pts compliance influenced survival so larger prospective studies that document stage and treatment are needed to determine if increased surveillance in the setting of a LS diagnosis leads to better OS.

Abstract Background. The utilization of hospital services is a benchmark for the success of a health care referral system. Indonesia as the largest archipelago in the world encounters challenging conditions along with lack of infrastructure posed economic and health disparity among its regions. Disparities as a result of this development also have an impact on the accessibility of health care facilities.Methods. Chi Square test was used to test dichotomy variables and t-tests were performed for analyzing the difference among continuous variables. These tests were employed to assess the hypothesis that there was significant regional difference in the access of health care in Indonesia. Estimation using multinomial logistic regression test was used to study the disparity between regions in hospital utilization.Results. The results of this study indicate that there were disparities between regions in Indonesia. In the inpatient category all regions have better utilization than the Papua region, except the Sumatra region. The highest disparity occurs between the Nusa Tenggara region and the Papua region. Possibility of utilizing hospital vs. inpatient facilities not using the hospital 1,439 times in adults in the Nusa Tenggara region compared to the Papua region (OR = 1,439; 95% CI = 1,271 - 1,629). In the category of outpatient utilization as well as hospitalization in hospitals, the Papua region has better hospital utilization compared to other regions. The greatest disparity with the Sumatra region (OR = 0.484; 95% CI = 0.392 - 0.597).Conclusion. In conclusion, there were disparities between regions in Indonesia even though the odds ratio for mortality between regions decreased compared to the previous period.Ethical Clearance. The 2013 RISKESDAS survey had ethical clearance that was approved by the national ethical committee in the NIHRD (ethic number: 01.1206.207). Informed consent was used during data collection, which considered aspects of data collection procedure, voluntary, and confidentiality.

Purpose. Regular physical activity is a cornerstone in the prevention and treatment of cardiovascular disease thanks to its anti-inflammatory effects. Thus, favoring the access to sports is of importance for promoting well-being. The aim of the present study was to investigate how the practice of different sports is distributed among different age groups and between men and women, by taking a picture of the medical certificate request in 2017 for sports in the population of the province of Modena, Italy. Methods. We analyzed the difference in distribution of requested medical certificate from 18 874 males and 7625 females stratified for age (<18 years, 18-40 years, and >40 years) and for different sporting disciplines (athletics, football, bike, swimming, basketball, volleyball, tennis, other team sports, other individual sports, and disabled sports). Results. Men requested medical certificates more than women (more than 2.5 times). The distribution of requested certificates differs significantly (chi-square test P < .0001) at different ages and between males and females of same age. Certificate for men aged less than 18 years were 7550 and for women were 4131 and the difference increase with age. Conclusions. In order to decrease the imbalance between men and women access to sports, it is mandatory to promote a healthy lifestyle and reduce, as consequence, cardiovascular risks, mostly in women after 40 years.

Abstract Background Neurocysticercosis is a Neglected Tropical Disease and an important public health issue. Our goal was to collect and analyze data regarding clinically significant gender differences among our Neurocysticercosis patients. Methods A retrospective chart search with ICD 9/ ICD 10 diagnostic code for Neurocysticercosis and neuroimaging suggestive of Neurocysticercosis was performed for clinical encounters in the hospital or affiliated clinics between years 2013–2018. After a careful chart review, patients who were clinically diagnosed with Neurocysticercosis were included in the study. T-test was used to compare means of continuous variables and chi-square test to compare proportions of categorical variables. Results Among 90 total patients included, male (49.4%) and female (50.6%) distribution were nearly identical. The mean age in females was found to be higher than males (52.5 vs 42.0, P &lt; 0.0001). Almost an equal number of males and females presented with either seizures (63.6% vs 57.8%, P= 0.85), headaches (25.0% vs 28.9%, p= 0.85), or other symptoms (11.4% vs 13.3%, p= 0.85). Males had more generalized seizures compared to females (60% vs 38%, P= 0.37), although this result was not statistically significant. Females were more likely to present with &gt; 1 lesion (82.2% vs 56.8%, P= 0.01). Males were more likely to have cystic lesions (64.7% vs 27.9%, P &lt; 0.001) compared to females who had more calcified lesions on presentation (65.1% vs 20.6%, P &lt; 0.001). Male patients were more likely to have contrast enhancement or edema surrounding the lesions (61.4% vs 33.3%, P= 0.01) and were more likely to require treatment with Albendazole/Praziquantel (75.8% vs 31.7%, P &lt; 0.001). Conclusion Although previously reported data is limited, there is a suggestion that there are gender differences in host immune response and that inflammation surrounding parenchymal lesions is more intense in females. This study suggests that men either present early in the disease phase or have different immune responses than women and require anti-parasitic therapy more frequently. More research in this aspect is needed. Disclosures All Authors: No reported disclosures

Abstract Objective: To assess the diagnostic ability of abbreviated protocols of MRI (AP-MRI) compared with unenhanced MRI (UE-MRI) in mammographically occult cancers in patients with dense breast tissue.Materials and Methods: The retrospective analysis consisted of 102 patients without positive findings on mammography who received preoperative MRI full diagnostic protocols (FDP) between January 2015 and December 2018. Two breast radiologists read the UE, AP, and FDP. The interpretation times were recorded. The comparisons of the sensitivity, specificity and area under the curve of each MRI protocol, and the sensitivity of these protocols in each subgroup of different size tumors used the Chi-square test. The paired sample t-test was used for evaluating the difference of reading time of the three protocols.Results: Among 102 women, there were 68 cancers and two benign lesions in 64 patients and 38 patients had benign or negative findings. Both readers found the sensitivity and specificity of AP and UE-MRI were similar (p>0.05), whereas compared with FDP, UE had lower sensitivity (Reader 1/Reader 2: p=0.023, 0.004). For different lesion size groups, one of the readers found that AP and FDP had higher sensitivities than UE-MRI for detecting the lesions ≤10 mm in diameter (p=0.041, p=0.023). Compared with FDP, the average reading time of UE-MRI and AP was remarkably reduced (p < 0.001).Conclusion: AP-MRI had more advantages than UE-MRI to detect mammographically occult cancers, especially for breast tumors ≤10 mm in diameter.
