    AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

    Bu çalışmanın amacı paletli yüzme (monopalet) ve yüzme sporcularının beslenme bilgi düzeylerini incelemektir. Çalışmaya 94 Elit Paletli yüzücü ve 81 elit yüzücü olmak üzere toplam 175 sporcu gönüllü olarak katılmıştır. Çalışmada araştırmacılar tarafından oluşturulan “Demografik Bilgi Formu” ve yüzücülerin beslenme bilgi düzeylerini belirlemek için Çırak ve Çakıroğlu (2019) tarafından geliştirilen “Beslenme Bilgi Düzeyi” anketi kullanılmıştır. Verilerin normal dağılım gösterip göstermediğine Kolmogorov Smirnov testi ile bakılmıştır. Verilerin normal dağılım göstermediği tespit edilmiştir. İki grup karşılaştırmalarında Man-Whitney U testi, üç ve daha fazla grup karşılaştırmalarında ise Kruskall Wallis testi kullanılmıştır. Çalışmada yüzme ve paletli yüzme sporu ile uğraşan elit sporcuların beslenme bilgi düzeyleri incelendiğinde, paletli yüzme sporcularının beslenme bilgi düzeyi puanlarının yüzme sporcularına göre daha yüksek olduğu tespit edilmiştir (p&lt;0,05). Sporcuların beslenme bilgi düzeyi puanları eğitim durumu ve milli sporcu musunuz? değişkenlerine göre alt boyut ve genel toplam puanlarında istatistiksel olarak anlamlı farklılık tespit edilirken (p&lt;0,05), cinsiyet, değişkenlerine göre beslenme bilgi düzeyi puanlarının istatistiksel olarak farklılaşmadığı tespit edilmiştir (p&gt;0,05). Haftada kaç saat antrenman yapıyorsunuz? sorusuna göre beslenme bilgi düzeyi puanları incelendiğinde haftada 8 saat ve daha az antrenman yapan sporcuların puanlarının 9 saat ve üzeri antrenman yapan sporculara göre daha düşük olduğu tespit edilmiştir (p&lt;0,05). Sonuç olarak paletli yüzme sporcularının beslenme bilgi düzeyleri yüzme sporcularından daha yüksek olduğu ortaya çıkmıştır.The aim of this study is to examine the nutritional knowledge levels of fin swimming (monopalet) and swimming athletes. A total of 175 athletes, 94 Elite Finned swimmers and 81 elite swimmers, participated in the study voluntarily. In the study, the "Demographic Information Form" created by the researchers and the "Nutrition Knowledge Level" questionnaire developed by Çırak and Çakıroğlu (2019) were used to determine the nutrition knowledge levels of the swimmers. The Kolmogorov Smirnov test was used to determine whether the data showed normal distribution or not. It was determined that the data did not show a normal distribution. The Man-Whitney U test was used for comparisons of two groups, and the Kruskall Wallis test was used for comparisons of three or more groups. In the study, when the nutritional knowledge levels of the elite athletes engaged in swimming and fin swimming were examined, it was determined that the nutritional knowledge level scores of the finned swimmers were higher than the swimmers (p&lt;0.05). Athletes' nutrition knowledge level scores, educational status and are you a national athlete? While there was a statistically significant difference in sub-dimension and general total scores according to the variables (p&lt;0.05). It was determined that the nutritional knowledge level scores did not differ statistically according to the variables of gender (p&gt;0.05). How many hours do you train per week? When the nutritional knowledge level scores were examined according to the question, it was determined that the scores of the athletes who trained for 8 hours or less per week were lower than those who trained for 9 hours or more (p&lt;0.05). As a result, it was revealed that the nutritional knowledge levels of the fin swimmers were higher than the swimmers

    Purpose of this study is to determine the relationship between body mass index (BMI), body weight (BW) and height variables and staticdynamic balance of athletes specialized in different branches. Totally 160 active athletes (21,34 +/- 2,58 years), 78 female (21,10 +/- 1,63 years), 82 male (21,56 +/- 3,23 years) who did not have any health problems participated in the study voluntarily. Biodex Balance System was used for balance measurement. Static equilibrium measurements were performed on a fixed platform and dynamic equilibrium measurements were performed on 2 different levels (levels 1 and 6). Normal distribution indicators of the data were analyzed by Kolmogorov-Smirnov test, Q-Q Plots and histogramgraphs and it was found that the data did not comply with the normal distribution. Spearman-Rho test was used for statistical analysis of the data. While there was a positive correlation between BMI, BW and height and dynamic balance values (Level 1 and 6) of the participants (p<0,01), a significant negative correlation was found between BMI and BW. (p<0.05). According to the acquiredresults, it can be said that individuals with higher BW and BMI values can achieve postural balance better but have more difficulty in compensating when they lose balance. It is suggested that individuals with long stature should do more balance trainings in order to be successful especially in branches that include dynamic movements

    The balance in the formation of high performance and the display of skill in all sports branches has an important place. The aim of the study is to compare the static and dynamic balance performances of individual athletes with team athletes. A total of 55 athletes, 29 team athletes and 26 individual athletes, currently licensed to perform sports, participated in the study. Static and dynamic balance performances of the athletes were determined by the Biodex isokinetic balance system. The Mann-Whitney U test was used to determine the difference between the static and dynamic balance performances of individual athletes and team athletes after analyzing through the SPSS software program. As a result of statistical analysis, there was no significant difference between static and dynamic balance performances of team athletes and individual athletes (p &lt;0.05). As a result, improved fitness performance is required for effective use of motor skills in all sports branches and high performance. But according to the sports branch, the need for equilibrium is different. For this reason, it can be said that it is more important to assess the balance performance between the branches in terms of the need, rather than to evaluate the balance performance as a team and individual sportsman.  Article visualizations
