Dysphagia was assessed using the score of EAT10, a self-administered questionnaire. Daytime sleepiness was evaluated by calculating the score of ESS, a self-administered questionnaire. To examine the correlation between the degree of dysphagia (EAT10 score) and the degree of daytime sleepiness (ESS score), Spearman's rank correlation coefficient was calculated. Logistic regression analysis was performed with the presence or absence of daytime sleepiness as the dependent variable and the presence or absence of dysphagia and basic attributes as the independent variables, and the effect of dysphagia on daytime sleepiness was evaluated using odds ratios and 95% confidence intervals.Results: EAT10 scores of 3 or higher accounted for 5.6% of the total number of participants. High ESS scores (3 or higher) were significantly more frequent in the high-EAT10score group (odds ratio, 3.92: 95% confidence interval, 1.54-10.1) when adjusting for the effects of gender, age, body mass index, alcohol consumption, and smoking.Conclusion: This study suggests that dysphagia may be associated with daytime sleepiness in Japanese workers. Even a method using only a simple self-administered questionnaire may enable early detection and treatment of dysphagia and excessive daytime sleepiness.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"80 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145016384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the \"Forum\" that the three authors subsequently contributed, they presented six more points of negative findings on exposure and health problems related to Minamata disease in a fragmented manner, without responding to the various issues that I had pointed out in the \"Reply.\" In the case of environmental pollution causing diseases such as Minamata disease, the tasks of researchers in the field of medicine and public health are to (1) investigate the temporal and spatial spread of health problems, (2) investigate the pathophysiological factors for the health problems caused by environmental pollution, and (3) establish diagnostic criteria based on toxicological and epidemiological information. However, the three authors' opinions and logic clearly indicate that they lacked a standard academic or practical approach to methylmercury poisoning to pursue these three points, and that their understanding of the pathophysiology of the disease was inadequate and the premise for pursuing a diagnosis was flawed. Through discussions in this forum, the inaction of experts in the fields of public health, neurology, and pathology with regard to Minamata disease, as insisted in my book, was considered to be further confirmed.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"80 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the early days of hygiene science in Japan, the results of nutritional epidemiology research by Dr. Kanehiro Takaki, a naval doctor who studied medicine in Kagoshima, on the prevention of beriberi, a national disease at the time, were highly regarded internationally. Since then, hygiene research on food ingredients has been vigorously pursued to expand from basic research to applied research, as exemplified by the development of the allithiamine. The symposium \"Food Ingredients and Hygiene: Exploring the Functions of Food Ingredients from Hygiene\" was organized by the Young Researchers Association at the 94th Annual Meeting of the Japanese Society for Hygiene (Kagoshima) to introduce recent research and examples of industry-academia collaboration. Young researchers involved in hygiene research on foods and food materials presented their recent work ranging from basic research, such as the functional evaluation of foods by animal experiments and the evaluation of the effects of polyphenols and yogurt on health, which have long been studied, to applied research leading to the commercialization of foods with useful physiological effects. This mini-review is a summary of the symposium. As the Young Researchers Association, we hope that this symposium/mini-review will encourage young researchers to become interested in various functions of food ingredients, conduct related research, and consider how to contribute their research results to society.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"80 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143459932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We examined the state of subjective health by assigning scores to the three-choice responses to each question (yes=3, sometimes=2, no=0 point). We then calculated the cumulative scale score for each of the 16 scales to determine the three groups' characteristics.Results: The 4 h<, 4 h>, and 0 h groups consisted of 480, 440, and 80 employees, respectively. The 4 h< group had significantly more complaints of eye fatigue, lack of energy, and others than the 4 h> group. The mean percentile of the scale score was significantly higher for the two scales of \"eyes/skin\" and \"depression\" in the 4 h< group than the 4 h> group. We compared the changes in scale scores between those who increased and those who decreased their VDT work time with those in the previous year. The group increased with VDT work time showed higher scores in the questions \"lack of energy recently\" and others. Regular exercise reduced the severity of complaints about depression.Conclusions: THI confirmed that prolonged VDT work has negative impacts on health. To reduce these negative impacts, surveys using THI are useful for determining preventive measures.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"80 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143732114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This denotes that light drinking has a preventive effect on cardiovascular diseases. Effects of alcohol drinking on lipid metabolism including an increase in HDL cholesterol concentration and a decrease in LDL cholesterol concentration are the main reasons for the anti-atherosclerotic action of alcohol. The antithrombotic effect of alcohol through the inhibition of platelet function is also involved in the lower incidence of ischemic arterial disease in drinkers. Capacitative Ca2+ entry, a main mechanism for platelet aggregation, is inhibited by ethanol. Ethanol also inhibits plasmalemmal phospholipase A2 activity and consequent thromboxane A2 production. French paradox is a phenomenon showing the merit of red wine consumption for the prevention of ischemic heart disease. In addition to ethanol, red wine contains anti-oxidative polyphenol compounds, represented by resveratrol, which has an antiplatelet action. Resveratrol also inhibits the capacitative Ca2+ entry in platelets. Furthermore, ethanol and resveratrol show a synergic inhibitory action on platelet aggregation, which may be caused by the reduction in the Ca2+ sensitivity of the contractile apparatus of platelets and the attenuation of COX-1 activity. Thus, the strength of the antithrombotic action is thought to differ depending on alcohol beverage. Decreases in concentrations of coagulation factors including fibrinogen are also involved in the alcohol-induced antithrombotic action. Alcohol drinking causes hemorrhagic diathesis as well as antithrombotic tendency.","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":"79 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142781394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
