Background Several studies have suggested that the exposure to cadmium （Cd） increased mortalities from renal diseases, cardiovascular diseases and malignant neoplasm, including lung cancer and prostate cancer among inhabitants living in Cd-polluted areas and factory workers. This study aimed to assess the influence of environmental exposure to Cd on long term outcome of inhabitants living in an area polluted by Cd. Methods A 22-year follow-up study was conducted with 3119 inhabitants （1403 men and 1716 women） living in the Cd polluted Kakehashi River basin in Japan. The subjects were divided into 4 groups according to the amount of urinary Cd level （〈3.0 μg/g creatinine （Cr）, 3.0-4.9 μg/g Cr, 5.0-9.9 μg/g Cr, and -〉10.0 μg/g Cr）. Mortality was calculated by the person-years method. Hazards ratios （HR） and 95% confidence intervals （CI） were assessed by the Cox＇s proportional hazard model. Results Compared with urinary Cd 〈3.0 μg/g Cr group, the HR of 5.0-9.9μg/g Cr and 〉10.0 μg/g Cr groups were significantly increased after adjustment for age in both sexes： 1.24 （95% Cl 1.01-1.51） and 1.48 （95% CI 1.17-1.90） for men; 1.64 （95% CI 1.17-2.28） and 1.78 （95% Cl 1.27-2.50） for women. The most frequent cause of death was malignant neoplasm in men and cardiovascular diseases in women. The significant increase in mortality risk for cardiovascular diseases was observed in the subjects with 〉10 μg/g Cr in both sexes： 1.79 for men （95% Cl 1.02-3.12） and 2.38 for women （95% Cl 1.11-5.07）. When the subjects were divided into 2 categories （〈20μg/g Cr and 〉20 μg/g Cr）, the HR of the urinary Cd 〉20 μg/g Cr group for nephritis and nephrosis were 4.82 （95% Cl 1.07-21.61） in men and 7.92 （95% Cl 1.77-35.33） in women, respectively. The significant increase was not observed for malignant neoplasm. Conclusion These results suggest a dose-response relationship between Cd body burden and mortality for cardiovascular diseases, cerebrovascular diseases and nephritis and nephrosis.

The Development of the “Monitoring Application for Inappropriate Expressions in Nursing Records”for PsyNACS^©

Journal of Computer and Communications 2024年第5期12卷 42-52页

作者： Hirokazu Ito yuko Yasuhara Tetsuya Tanioka Department of Nursing Institute of Biomedical Sciences Tokushima University Graduate School Tokushima Japan

Lengthening periods of hospitalization, increasing numbers of patients with age-related complications, and a shortage of nursing staff have been of great concern in medical psychiatry in Japan. Under these circumstances, countries such as Japan that face a super-aging society and a decline in the working-age population, have been recommended for use of advanced information and communications technology (ICT) to improve the efficiency of medical treatment and care. This study aims to develop the “Monitoring Application for Inappropriate Expressions in Nursing Records” for using PsyNACS©, which will enable psychiatric nursing plans to harness the advantages of ICT. The functions considered necessary are as follows: 1) identification of users who enter information;2) a necessary database for lists of inappropriate expressions;3) development of a matching function to recommend proper writing input and a warning function;and 4) a management function for an inappropriate expression list database. A demonstration experiment for developing the application in this study was conducted at a specialized psychiatric hospital. To introduce them to the application, nurses and nurse managers were informed about the system developed in this study, and a survey regarding their opinions on the functions of the application was conducted with ten nurse managers. The results were evaluated in terms of usefulness for nursing care, documentation, and the education of nurses from an ethical perspective. This study suggests that matching their input with an inappropriate expression database will allow nurses to record more appropriate expressions. From an ethical perspective, the ability to use appropriate expressions makes records more likely to withstand disclosure requests from patients and their families.

Protective role of electrophile-reactive glutathione for DNA damage repair inhibitory effect of dibromoacetonitrile

引用

Journal of Environmental Sciences 2022年第7期34卷 305-314页

作者： Yukako Komaki Koki Suganuma yuko Ibuki Graduate Division of Nutritional and Environmental Sciences University of ShizuokaShizuoka 422-8526Japan

Dibromoacetonitrile(DBAN) is a disinfection byproduct(DBP) and linked with cancer in rodents, but the mechanism of its carcinogenicity has not been fully elucidated. We recently reported that DBAN induced inhibition of nucleotide excision repair(NER). In this study, we investigated if glutathione(GSH) is involved in the DBAN-induced inhibition of NER. Human keratinocytes Ha Ca T were pretreated with L-buthionine-(S,R)-sulfoximine(BSO) to deplete intracellular GSH. BSO treatment markedly potentiated the DBAN-induced NER inhibition as well as intracellular oxidation. The recruitment of NER proteins(transcription factor IIH, and xeroderma pigmentosum complementation group G) to DNA damage sites was inhibited by DBAN, which was further exacerbated by BSO treatment. Our results suggest that intracellular GSH protects cells from DBAN-induced genotoxicity including inhibition of DNA damage repair.

Could we remain simply applying discount rate to evaluate the life quality of our future generations?

When we try to estimate future environmental costs resulting from our current economic activities,we usually calculate the present value of the consequences for our future generations by utilizing a discount rate as a standard economic *** popularity of this procedure is solely supported by its simplicity which assumes:(1)a perfect financial market over even 100 years,and(2)existence of a stable time preference between two consecutive periods for an individual *** apparent deficiency of this approach is that the present value of life quality of future generations varies to a large extent along an arbitrarily chosen discount *** a matter of fact,the discount rate,which could reflect the time preference as2%or 5%,matters when we predict current strategies of environmental protection for future *** applying a discount rate to evaluate the quality of our future generation,without clarifying the actual production mechanism behind this,is almost to the same as ignoring the fact that all of the goods are produced through an actual production process and that environmental degradation reduces the efficiency of that *** greatest concern for our future generations should not be given by an assumed discount rate,since the discount rate itself is determined by financial market conditions at certain points in time.
