Abstract A diet supplemented with cholic acid (CA), the primary 12α-hydroxylated bile acid, can induce hepatic lipid accumulation in rats without obesity. This study examined the effects of a CA-supplemented diet on blood pressure (BP). After acclimation, WKAH/HkmSlc rats (3 week old) were divided into two groups and fed with a control AIN-93-based diet or a CA-supplemented diet (0.5 g CA/kg) for 13 weeks. The CA diet increased systolic and diastolic BP as well as hepatic lipid concentrations in the rats. No changes were found in the blood sodium concentration. Urinary albumin concentration increased in CA-fed rats. An increase was observed in the hepatic expression of ATP binding cassette subfamily B member 1B that correlated BPs and urinary albumin concentration accompanied by an increase in portal taurocholic acid concentration. These results suggest that 12α-hydroxylated bile acids are involved in increased BP and albuminuria via alteration of hepatic function.

Nurse education in practice 65 103486 - 103486 2022.11 [International journal]

AIM: This study described nursing students' cognitive changes as they acquire psychomotor skills through blended learning. BACKGROUND: Deliberate practice, including feedback from teachers, is vital for acquiring psychomotor skills. Blended learning, a program that allows students to deepen their learning and improve their skills even when students and faculty are physically separated has attracted significant attention in recent years. Although blended learning has been used for learning in the cognitive domain, no study has examined its effectiveness in the acquisition of psychomotor skills. Understanding how students' cognition changes as they acquire skills in a blended learning environment could be a valuable resource for effective teaching. DESIGN: An inductive, qualitative description approach was adopted. METHODS: The program involved a basic nursing skill: making an occupied bed. Eleven second-year nursing students participated. The participants attended face-to-face lectures and e-learning courses comprising self-study content that was designed for easy and frequent reference. Students practiced for a skill test, which was conducted one month after the first lecture. Two interviews were conducted approximately one month apart. Before each interview, the participants' current practices were videotaped. During the interviews, they explained their thought processes and conscious awareness of their actions as they watched the videos. This study was conducted between April and May 2019. RESULTS: Six categories related to changes in participants' cognitive processes while acquiring the skill of making an occupied bed were identified: "feeling that it is easy to acquire," "practicing without much thought," "realizing the difficulty in translating thoughts into practice," "experiencing a sense of purpose in each technique," "gaining a perspective to evaluate one's skills," and "developing one's unique approach." CONCLUSIONS: In a blended learning environment, where a practice environment and audiovisual materials were provided, students could practice and improve their skills at their own pace even without the instructor's frequent advice. The findings show that metacognitive skills are essential to the development of psychomotor skills in a blended learning program because this program requires practicing while monitoring one's skills. Metacognitive skills affect the development of psychomotor skills and the ability to provide care. Therefore, initiatives that address the development of metacognitive skills, such as the current program, during the early stages of basic education programs can contribute to the development of nursing students' practical skills.

BACKGROUND: Despite a long average lifespan, increased life expectancy does not guarantee higher quality of life. METHODS: To contribute in understanding some determinants of healthy life expectancies in older Japanese individuals in a snowy winter region, we investigated the indicators of health. Local residents (n = 124) in the city of Iwamizawa volunteered for health examinations from January 2016 to March 2016. We recorded activity via daily steps for 2-week periods. In addition, we measured body composition, grip strength, and assessed nutritional status. RESULTS: Analysis of body composition and daily activity indicated that women who walked more than 4000 steps had lower fat mass and increased muscle mass. Men with >3.0 metabolic equivalents (METs) when walking had lower body fat. CONCLUSION: For healthy older Japanese individuals in this snowy winter region, walking >4000 steps daily for women and exercise of >3.0 METs for men may indicate health-promoting activities.

Lipids in health and disease 19 ( 1 ) 137 - 137 2020.06 [Refereed] [International journal]

BACKGROUND: Inbred strains are characterized by less genetic variation, which suggests usefulness of inbred strains for evaluations of various parameters. In this study, experimental reproducibility in several parameters was compared between an outbred Wistar rat and Wistar King A Hokkaido (WKAH/HkmSlc) rat, the inbred strain that is originated from Wistar rats. METHODS: Difference of variations was investigated in parameters of body compositions and liver functions such as body weight, liver weight, liver triglycerides (TG), liver cholesterol and plasma alanine aminotransferase activity (ALT) between WKAH rats and outbred Wistar rats by using the coefficient of variation (CV). RESULTS: There was no difference in the CVs of body weight and relative liver weight between WKAH and Wistar rats. The CVs of body weight and relative liver weight were below 10% in both WKAH and Wistar rats. The CVs of TG, cholesterol, and ALT in Wistar rats were between 30 and 40%, whereas those in WKAH rats were between 10 and 25%. A low CV level of TG was observed in WKAH rats compared to that in Wistar rats regardless of the duration of the experimental period in those rat strains. CONCLUSION: The low CV values in metabolic parameters involved in liver functions in the inbred rats suggested an advantage of using inbred rather than outbred rats for the evaluation of liver lipid metabolism.

BMC medical education 19 ( 1 ) 53 - 53 2019.02 [Refereed] [International journal]

BACKGROUND: Nurses are responsible for implementing appropriate measures to reduce hospital infections, especially with multidrug resistant bacteria, so nursing students should learn about microbiology. This helps them to understand bacterial dissemination and infectious disease control. Because of tight schedules, however, its teaching is limited in undergraduate nursing classes in Japan. We therefore tested whether a simple short practical session in a microbiology class could help to improve undergraduate nursing students' awareness of bacterial traits and how to prevent infections. METHODS: This study involved second-grade nursing students (n = 76). Two short practical sessions (a total of 3 h, across 2 days) were used to assess the effectiveness of washing or disinfection on hand bacteria in a 16-class microbiology course (total class time was 24 h, plus an exam). Hand bacteria were sampled on LB agar plates with orientation during the first half-day, and the plates examined for colonies with distinct color or morphological traits, and discussed, in the second session, a week later. Questionnaires before and after the exercise were used to assess changes in awareness of unseen bacteria inhabiting around us connecting bacterial traits and how to prevent infections. RESULTS: The results showed that the practical increased the nursing students' awareness of fomites (utensils) (p = 0.0115), fomites (contact-based) (p = 0.0016), habitats (body surface) (p = 0.0127), action facilitating hospital infection (p = 0.0166), and changes in physical condition caused by bacterial infections (p = 0.0136). There were no changes in word associations (p = 0.627) or habitats (inside body) (p = 0.308). Difficulty score, which is an element in questionnaire psychometric properties, tended to be close to the expected score through the practical, but not statistical significant. In addition, regardless of before or after practical, Cronbach α score, which is an indicator of the reliability among items of multi-choice questions, showed > 0.8, indicating validity of evaluation items. Thus, the student's awareness of unseen bacteria inhabiting around us was significantly increased as compared to those before practical in microbiology class. CONCLUSIONS: The simple short practical effectively improved nursing students' awareness of unseen bacteria inhabiting around us in microbiology course, useful for even tight teaching schedules.

PloS one 14 ( 12 ) e0226952 2019 [Refereed] [International journal]

We monitored the survival of human pathogenic bacteria [Escherichia coli (ATCC), extended-spectrum β-lactamase-producing E. coli (Clinical isolate), New Delhi metallo-β-lactamase-producing E. coli (clinical isolate), Staphylococcus aureus (ATCC)] on dry materials (vinyl chloride, aluminum, plastic, stainless steel) at distinct temperatures (room temperature or 15°C-37°C). These bacteria favored a lower temperature for their prolonged survival on the dry fomites, regardless of the material type. Interestingly, when mixed with S. aureus, E. coli survived for a longer time at a lower temperature. Cardiolipin, which can promote the survival of S. aureus in harsh environments, had no effect on maintaining the survival of E. coli. Although the trends remained unchanged, adjusting the humidity from 40% to 60% affected the survival of bacteria on dry surfaces. Scanning electron microscopic analysis revealed no morphological differences in these bacteria immediately before or after one day of dry conditions. In addition, ATP assessment, a method used to visualize high-touch surfaces in hospitals, was not effective at monitoring bacterial dynamics. A specialized handrail device fitted with a heater, which was maintained at normal human body core temperature, successfully prohibited the prolonged survival of bacteria [Enterococcus faecalis (ATCC), E. coli (ATCC), Pseudomonas aeruginosa (ATCC), S. aureus (ATCC), Acinetobacter baumannii (clinical isolate), and Serratia marcescens (clinical isolate)], with the exception of spore-forming Bacillus subtilis (from our laboratory collection) and the yeast-like fungus Candida albicans (from our laboratory collection)] on dry surfaces. Taken together, we concluded that the tested bacteria favor lower temperatures for their survival in dry environments. Therefore, the thermal control of dry fomites has the potential to control bacterial survival on high-touch surfaces in hospitals.

Factors Affecting Bone Mineral Density Among Snowy Region Residents in Japan: Analysis Using Multiple Linear Regression and Bayesian Network Model.

Teppei Suzuki, Tomoko Shimoda, Noriko Takahashi, Kaori Tsutsumi, Mina Samukawa, Sadako Yoshimura, Katsuhiko Ogasawara

Interactive journal of medical research ( Journal of Medical Internet Research ) 7 ( 1 ) e10 2018.05 [Refereed] [International journal]

BACKGROUND: As the onset of osteoporosis leads to reduced activities of daily living and may result in patients being bedridden, efforts to prevent decreased bone density are necessary. Various studies on the relationship between sex, age, nutrients, and exercise habits and bone mineral density have been conducted to date. However, for snowy region residents, the magnitude of influence of various factors affecting bone mineral density and the influence level have not been clarified. OBJECTIVE: This study aimed to clarify the degree of influence and factors influencing bone mineral density based on survey results on health conditions and lifestyle habits in heavy snow areas. METHODS: A total of 354 citizens who visited a drugstore in the target area were included in a study that included using the brief-type self-administered diet history questionnaire on lifestyle and exercise habits. Height, weight, body composition, and bone densitometer values were analyzed using multiple regression to calculate their association with bone mineral density. In addition, a Bayesian network model was used to determine the influence level of each factor as a conditional probability. RESULTS: Multiple regression analysis revealed that age, sex, fracture, and calcium intake significantly influenced bone mineral density. In addition, the result of Bayesian network analysis suggested that age and sex affected bone mineral density, whereas nutrients and exercise habits might not have a direct impact. However, calcium intake and the T-score were significant factors affecting the presence or absence of fracture experiences, suggesting that adequate calcium intake is essential for preventing fractures. CONCLUSIONS: In the multiple regression analysis, age, sex, fracture, and calcium intake were selected as factors; however, in the Bayesian analysis, only age and sex affected bone mineral density while nutrients did not. In addition, the fact that calcium intake and the T-score were shown to affect bone fracture history suggests that calcium intake is an important measure that can prevent bone fractures. Overall, these results suggest that measures such as ensuring a bone fracture-free environment and providing nutritional advice for calcium intake can be effective in preventing bone loss.

北海道公衆衛生学雑誌 ( 北海道公衆衛生学会 ) 31 ( 2 ) 77‐84 - 84 2018.03

医療施設で発生する音に対する快・不快の評価と、その音が何であるかを確信している程度(音確信度)がどのように関係しているか、およびこの音確信度に影響する要因について明らかにし、今後の医療施設等での音環境への配慮に対して示唆を得ることを研究目的とした。対象者は20歳以上の学生23名で、疑似病室内で20種類の音を再生し、各音に対する快・不快評価、その音が何だと思うか、音確信度、音を聞いた経験の有無について調査した。その結果、音確信度が高い方が快い傾向にある音と、音確信度が高い方が不快な傾向にある音があった。音を聞いた経験があることは音確信度を向上させ、音の種類について事前にまとめて説明することは音確信度を高めず、むしろ低下させる場合があった。音の正答率と音確信度には有意に正の相関があった。以上のことより、医療施設で発生する音の種類によって、配慮方法を使い分けることが重要と示唆された。(著者抄録)

Previous works have demonstrated considerable variability in hospital cleanliness in Japan, suggesting that contamination is driven by factors that are currently poorly controlled. We undertook 16S rRNA sequence analysis to study population structures of hospital environmental microbiomes to see which factor(s) impacted contamination. One hundred forty-four samples were collected from surfaces of three hospitals with distinct sizes ("A": >500 beds, "B": 100-500 beds, "C": <100 beds). Sample locations of two ward types (Surgical and Internal) included patient room bed table (multiple) (4BT), patient overbed table (multiple) (4OT), patient room sink (multiple) (4S), patient room bed table (single) (SBT), patient overbed table (single) (SOT), patient room sink (single) (SS), nurse desk (ND), and nurse wagon (NW). Total DNA was extracted from each sample, and the 50 samples that yielded sufficient DNA were used for further 16S rRNA sequencing of hospital microbiome populations with cluster analysis. The number of assigned bacterial OTU populations was significantly decreased in hospital "C" compared to the other hospitals. Cluster analysis of sampling locations revealed that the population structure in almost all locations of hospital "C" and some locations in the other hospitals was very similar and unusually skewed with a family, Enterobacteriaceae. Interestingly, locations included patient area (4OT, 4BT, SBT) and nurse area (ND), with a device (NW) bridging the two and a place (4S and SS) shared between patients or visitors. We demonstrated diversity changes of hospital environmental microbiomes with a skewed population, presumably by medical staff pushing NWs or sinks shared by patients or visitors.

Lifestyle diseases, which are associated with nutrition, account for 30% of elderly requiring long-term care. To increase health expectancy among Japan's rapidly aging population, we investigated the nutritional status and body composition of elderly adults living in a region subject to heavy snowfall, to identify pertinent health indicators. The dietary habits of 288 local residents aged >= 50 years were analyzed using body composition and a brief-type self-administered diet history questionnaire. Body mass index of all residents was normal. Basal metabolic rate (BMR) and muscle mass were reduced in the older group. Dietary habits did not differ with age among men, but older women had significantly higher dietary intake. BMR and muscle mass declined with age, even when dietary intake was sustained. Despite sufficient dietary intake, independently living older adults demonstrate less efficient use of food with age. Interventions to reduce excessive sodium and protein intake are required.
