Factors Influencing Willingness to Undergo Lung Cancer Screening in the Future: A Cross-Sectional Study of Japanese University Students.

Lung cancer (LC) is currently the leading cause of cancer deaths in Japan. Early detection through lung cancer screening (LCS) is important for reducing mortality. Therefore, exploring the factors affecting willingness to undergo LCS, particularly among young people, is important. This study aimed to elucidate the inclination toward LCS and its determining factors among Japanese university students. This cross-sectional study, involving 10,969 Japanese university students, was conducted in April 2023. A Pearson's chi-square test and a binomial logistic regression analysis were used to analyze factors related to the dependent variable, willingness to undergo LCS in the future. Out of the 6779 participants (61.8%) involved in this study, 6504 (95.9%) provided valid responses, and 4609 (70.9%) expressed a willingness to undergo LCS in the future. Analysis revealed current smoking as a barrier to future willingness to undergo LCS. Other barriers included postponing the age of screening, anxiety about the screening content, and concerns about the possibility of having cancer after screening. Addressing barriers, such as current smoking and anxiety about screening, that prevent young people from undergoing LCS in the future is crucial. Therefore, universities should provide opportunities to educate students about LCS and explore various educational methods.

Association between the experience of exertional heat illness (EHI) and living conditions of collegiate student athletes.

Exertional heatstroke (EHS), a severe form of exertional heat illness (EHI), is the third leading cause of death in athletes; thus, early detection and prevention of EHI can help prevent EHS, which is a life-threatening condition. This study aimed to clarify the association between the cognizance of experiencing EHI and living conditions and specific EHI symptoms among collegiate athletes. This study was conducted in October 2022 by administering a questionnaire to 237 male collegiate athletes. Of the 215 (90.7%) respondents, 197 (91.6%) provided valid responses; among them, 88 (44.7%) responded they had experienced EHI, while 109 (55.3%) had not. A history of medical examinations due to EHI, having experienced headaches during summer activities, and having read the EHI manual were factors indicating cognizance of EHI. The number of times meals containing a staple food, main dish, and side dish were eaten in a day was a factor in preventing EHI. Early detection of EHI is important for its prevention, and it is important that athletes themselves have knowledge of symptoms and can correctly self-diagnose EHI. Emphasizing the potential of a well-balanced dietary intake has the potential to prevent EHI is crucial.

Beta-Ketothiolase Deficiency: Resolving Challenges in Diagnosis

Abstract Beta-ketothiolase deficiency is an inherited disorder of ketone body metabolism and isoleucine catabolism. It typically manifests as recurrent ketoacidotic episodes with characteristic abnormalities in the urinary organic acid profile. However, several challenges in the diagnosis of beta-ketothiolase deficiency have been encountered: atypical presentations have been reported and some other disorders, such as succinyl-CoA:3-oxoacid CoA transferase and 2-methyl-3-hydroxybutyryl-CoA dehydrogenase deficiencies, can mimic the clinical and/or biochemical signs of beta-ketothiolase deficiency. A final diagnosis of beta-ketothiolase deficiency requires an enzymatic assay and/or a molecular analysis, but some caveats must be considered. Despite the reported missed cases, screening programs have successfully identified an increasing number of patients with beta-ketothiolase deficiency. Early diagnosis and management of beta-ketothiolase deficiency will enable prevention of its serious acute and chronic complications and ultimately improve the prognosis.
