作者： Chiharu Miyata Hidenori arai Sawako Suga Department of Human Health Sciences Kyoto University Graduate School of Medicine Kyoto Japan Department of Nursing Kansai University of Nursing and Health Sciences Hyogo Japan

Objective: The purpose of this qualitative study was to obtain a better understanding of nurse manager’s recognition behavior. Methods: This study, consisting of semi-structured interviews, was conducted in five hospitals with 100 beds or more in the Kanto, Kansai, and Kyushu regions of Japan. Fifteen nurse managers, who each had more than one year of professional work experience as a nurse manager, participated in this study. Results: We extracted four categories and fourteen subcategories as the factors related to the recognition behaviors in nurse managers. The first category is the basis of the recognition behaviors, which were divided into the following four subcategories: recognition behaviors that they received, perception of recognition behaviors, construction of confidential relationships with staff nurses, and the organizational climate. The second category is the issues that make recognition behaviors difficult, which were classified into the following three subcategories: multiple duties, number of staff nurses, and characteristics of the recent staff nurses. The third category is the factors regarding the staff nurses that must be considered, which consist of the following two subcategories: the characteristics and motivation of staff nurses and recognition behaviors that the staff nurses expect. The forth category is the methods of the recognition behaviors, which consist of the following five categories: watching over and consideration of individuals, evaluation of routine work, development as a professional, opinion sharing and delegating work, and promotion of work-life balance. Conclusions: The recognition behavior by nurse managers is influenced by their own experience, and nurse managers practice recognition behaviors in response to the characteristics of their staff nurses in a busy environment. Our results suggest that nurse managers need expertise in management for them to identity appropriate recognition behavior.

Balloon-occluded transcatheter arterial chemoembolization for hepatocellular carcinoma

引用

World Journal of Hepatology 2018年第7期10卷 485-495页

作者： Takeshi Hatanaka Hirotaka arai Satoru Kakizaki Department of Gastroenterology Saiseikai Maebashi Hospital Department of Gastroenterology Maebashi Red Cross Hospital Department of Gastroenterology and Hepatology Gunma University Graduate School of Medicine

Transcatheter arterial chemoembolization(TACE) is widely accepted as a treatment for patients with hepatocellular carcinoma(HCC) in the intermediate stage according to the Barcelona Clinic Liver Cancer(BCLC) guidelines. Recently, balloon-occluded TACE(B-TACE) was developed in Japan. Despite the lack of a clear definition, B-TACE is generally defined as the infusion of emulsion of chemotherapeutic agents with lipiodol followed by gelatin particles under the occlusion of feeding arteries by a microballoon catheter, which leads to the dense lipiodol emulsion(LE) accumulation in HCC nodules. This phenomenon cannot be explained only by the prevention of proximal migration and leakage of embolization materials; it further involves causing local changes in the hemodynamics of the surrounding occlusion artery and targeted HCC nodules. Balloon-occluded arterial stump pressure plays an important role in the dense LE accumulation in targeted HCC nodules. Although randomized controlled trials comparing the therapeutic effect and the prognosis of B-TACE to those of the other TACE procedures, such as conventional-TACE and drug-eluting beads TACE, are still lacking, B-TACE is thought to be a promising treatment. The purpose of this review is to summarize the mechanism, therapeutic effect, indication, prognosis and complications of BTACE.

Wound Closure on the Neonatal Rat Skin I. The Modulation of the Thickness of Epidermis at the Closing Incisional Wounds

引用

CellBio 2013年第4期2卷 248-256页

作者： Mary arai Takashi Matsuzaki Setsunosuke Ihara Department of Biological Science Faculty of Life and Environmental Science Shimane University Matsue Japan

Full-thickness incisional wounds were made on the dorsal skin of 1-day-old rats to elucidate the mechanism of the fluctuation of the epidermal thickness after the wound closure. The thickness of the epidermis covering the wound reached a peak around 96 h post-wounding (PW), and became thinner thereafter. The analyses of the cell proliferation and apoptosis at the epidermal wound regions revealed that the rate of TUNEL-positive cells that displays the cells undergoing apoptosis increased as the epidermis became thinner around 120 h PW. Next, immunohistochemical analyses using antibodies against keratinocyte differentiation marker proteins indicated that the delay or interruption of the spinous to granular transition from 96 to 120 h PW might result in the epidermal thickening in the wound region. Third, the region undyed with anti-caspase-14 antibody extended downward in the thickened epidermis by 96 h PW, and in turn, it became intensely and widely stained with this antibody in the thinning epidermis by 120 h PW. Taken together, it is likely that the delay and acceleration of the terminal differentiation, including cornification of the epidermal keratinocytes may coordinately cause the fluctuation of the thickness of the epidermis at the wound site in rat neonates.

According to the reports from Ministry of Health in each country, the average life span is elongated over the past decade. This trend is expected to be keeping constant further in the future and at the same time continued efforts should be made. Next, it is necessary for us to consent about improving the quality of life. In an effort of improving the quality of life, other than the western medicine, we have attempted to introduce many traditional medical practices, including the oriental medicine, from various parts of the world into the medical field as a complementary & alternative medicine (CAM). Judging both positive and negative aspects by the evaluation standard of the Western medicine, we try to obtain numerical aspects in termed of QOL. Some methods of alternative medicine involved in this review are acupuncture, moxibustion, TCM and other traditional medicine. Above all, WHO suggests selecting the suzerain nation of acupuncture moxibustion, which has been developed in the oriental countries as a specialized cure, by identifying merits & demerits and ascertaining which nation can be a the best model for special field. At the moment for evaluating CAM, for example, what kind of methods is/are suitable for evaluating each CAM. We have been trying to propose the peripheral leukocyte, that is one of the best marker for evaluating CAM. Our trial is a hot spring hydrotherapy, acupuncture and moxibution, light exercise and Ondle/floor heating etc. In these trials, we find the common results from leukocyte effects which exhibit a strong correlation for the regulation in number and function, as a new scale for evaluating QOL. The contents are the result from the data showing the much in number of volunteer tend to down regulate, on the other hand, lower number of volunteer is up-regulated at next day by each menu of CAM as a constitution dependent manner. However, even in western medical methodology, double blind and cross over system are the better way to evaluation

Open Journal of Nursing 2013年第1期3卷 16-24页

作者： Mika Okura Chizuko Noro Hidenori arai Department of Human Health Sciences Kyoto University Graduate School of Medicine Kyoto Japan Department of Human Nursing Sonoda Women’s University Amagasaki Japan

Objective: The purpose of this study was to develop a career-orientation scale for public health nurses (PHNs) and to validate the scale. Methods: Self-administered questionnaires were sent to 7170 PHNs in 10 prefectures. A retest survey was sent to 252 participants. Results: The valid responses from 2003 PHNs in the first survey were analyzed for major factors by varimax rotation. The analysis resulted in five orientation factors and 19 items being selected. The cumulative contribution ratio was 46.9%, and Cronbach’s coefficient alpha was 0.863. The exact match ratio of test-retest was 59.7% (from 47.7% to 72.1% for each item and from 12.0% to 92.0% for each participant). Conclusions: The reliability and validity of this survey were confirmed;however, further research is required to confirm the reproducibility. This scale can be used as a self-assessment tool when managers need to advise their staff on career development.

To provide quantitative feedback on surgical progress to ophthalmologists practicing inner limiting membrane(ILM)peeling,we developed an artificial eye module comprising a quartz crystal resonator(QCR)force sensor and a strain body that serves as a uniform force transmitter beneath a retinal *** a sufficiently large initial force must be loaded onto the QCR force sensor assembly to achieve stable contact with the strain body,the highly sensitive and wide dynamic-range property of this sensor enables the eye module to detect the slight forceps contact force.A parallel-plate strain body is used to achieve a uniform force sensitivity over the 4-mm-diameter ILM peeling *** these two components allowed for a measurable force range of 0.22 mN to 29.6 N with a sensitivity error within−11.3 to 4.2%over the ILM peeling *** this eye module,we measured the applied force during a simulation involving artificial ILM peeling by an untrained individual and compensated for the long-term drift of the obtained force data using a newly developed *** compensated force data clearly captured the characteristics of several types of motion sequences observed from video recordings of the eye bottom using an ophthalmological *** a result,we succeeded in extracting feature values that can be potentially related to trainee skill level,such as the mean and standard deviation of the pushing and peeling forces,corresponding,in the case of an untrained operator,to 122.6±95.2 and 20.4±13.2 mN,respectively.

Heavy metal concentrations in muscle and their relation to thegrowth of two marine fish species,including tonguefish( Cynoglossus arel) and mullet( Mugil cephalus),were studied. The samples were collected in Bach Dang estuary andconcentrations of heavy metals( As,Cd,Co,Mn,Cu,Zn,Pb,and V) in muscle of the fisheswere determined. The result showed that the accumulated trend of heavy metal is different between fish species. The concentration of As,Zn,Mn,V,Cu,Pb,Co and Cd in tonguefish were 73. 7 ± 30. 6,22. 82 ± 4.87,3. 44 ± 2. 13,1. 61 ± 0. 15,0. 71 ± 0. 13,0. 45 ± 0. 24,0. 03 ± 0. 02 and 0. 02 ± 0. 02 mg·g-1,respectively. Meanwhile the concentration of Zn,As,V,Mn,Cu,Pb,Co and Cd in mullet were 83. 41 ±19. 68,9. 78 ± 1. 92,1. 36 ± 0. 54,1. 29 ± 0. 51,0. 65 ± 0. 12,0. 42 ± 0. 20,0. 06 ± 0. 03 and0. 03 ± 0. 01mg·g-1,respectively. Comparison of metal levels among thesespecies indicated that the concentrations of As and Mn in tonguefish were significantly higher than those in mullet,whereas Zn levels in mullet were found to be higher than that in tonguefish. There is no significant differences of Cd,Co,Cu,Pb and V levels in muscle between two species. Significant inversed relationshipsbetween concentration levels of metals and lengths of tonguefish were found for Mn,Cu and Zn,butnot for As,Cd,Pb,and V. There were no significant relationships between the heavy metal concentrations and the length of mullet. In general,decreasesof the heavy metal concentrations corresponded to the increases of fish body lengths,particularly for As,Co,Cu,Mn and V and the exception for Cd. Terefore reduced risks were associated with consuming biggermullet fish,and increased risks of As and Cd were associated with consuming bigger tonguefish in Bach Dang river mouth.

Nurse Managers Stress and Coping

引用

Open Journal of Nursing 2015年第11期5卷 957-964页

作者： AChiharu Miyata Hidenori arai Sawako Suga Department of Human Health Sciences Kyoto University Graduate School of Medicine Kyoto Japan National Center for Geriatrics and Gerontology Obu Aichi Japan Department of Health Sciences Kyoto Tachibana University Kyoto Japan

Objective: The purpose of this study was to gain insight into nurse managers’ stress experiences and coping strategies in order to better support them. Design: A qualitative exploratory descriptive research design was used in this study. Subject: Fifteen nurse managers participated in this study. Results: Three descriptive themes related to nurse managers’ occupational stress were identified: role overload, loneliness, and role conflict. We also identified three descriptive themes that contributed to their stress management: sufficient support and advice, taking mental breaks while off duty, and individual coping strategies. Conclusions: Our study proposes two recommendations to reduce nurse managers’ stress. First, for nurse managers who experience work overload, hospitals should support them in learning how to work efficiently and how to manage their response to work demands. Second, nurse managers’ primary stressors were loneliness and role conflict. Nurse managers are known to juggle multiple demands from the hospital nursing director and staff nurses. Although it is difficult to eliminate the role conflict, nurse managers should be guided on how to manage conflicting demands, the hospital nursing director and staff nurses.
