Purpose: Relative energy deficiency in sport (REDs) is a syndrome of physiological and/or psychological functioning experienced by female and male athletes that is caused by exposure to problematic low energy availability. For the prevention and intervention of REDs, awareness of REDs among sports physicians is important, but it is largely unknown. This study aimed to survey the awareness and clinical treatment experience of REDs in sports physicians. Methods: We conducted an online survey to assess awareness of the triad and REDs among sports physicians and members of The Korean Society of Sports Medicine. Results: A total of 69 members (62.2% male, including sports physicians) to this survey. Most participants (84.1%) were aware of the triad compared to fewer with awareness regarding REDs (23.2%). People who knew about the difference between REDs and triad was 33.3%, which was lower than those who did not (66.6%). Only 10.1% of the study subjects had experience treating REDs patients, and the biggest difficulty in treating patients was a lack of information and education (50.7%). It appeared that the most information about REDs was obtained from academic conferences (59.4%). Conclusion This survey found relatively low awareness of REDs among physicians treating athletes and sports professionals. Considering the various negative effects of REDs on athlete health and performance, education and promotion are needed to increase awareness among sports physicians and sports professionals.

Background: The increasing rate of excess body weight (EBW) in the global population has led to growing health concerns, including cancer-related EBW. We aimed to estimate the population attributable fraction (PAF) of cancer incidence and deaths linked to EBW in Korean individuals from 2015 to 2030 and to compare its value with various body mass index cutoffs. Methods: Levin’s formula was used to calculate the PAF; the prevalence rates were computed using the Korean National Health and Nutrition Examination Survey data, while the relative risks of specific cancers related to EBW were estimated based on the results of Korean cohort studies. To account for the 15-year latency period when estimating the PAF in 2020, the prevalence rates from 2015 and attributable cases or deaths from 2020 were used. Results: The PAF attributed to EBW was similar for both cancer incidence and deaths using either the World Health Organization (WHO) Asian-Pacific region standard or a modified Asian standard, with the WHO standard yielding the lowest values. In the Korean population, the PAFs of EBW for cancer incidence were 2.96% in men and 3.61% in women, while those for cancer deaths were 0.67% in men and 3.06% in women in 2020. Additionally, PAFs showed a gradual increase in both sexes until 2030. Conclusion The EBW continues to have a significant impact on cancer incidence and deaths in Korea. Effective prevention strategies targeting the reduction of this modifiable risk factor can substantially decrease the cancer burden.

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.
