Malnutrition and Its Association with the Mortality of Patients with Femoral Intertrochanteric Fractures: A Retrospective Analysis of Japanese Patients

引用

Open Journal of Orthopedics 2024年第1期14卷 22-31页

作者： Taizo Kaneko kyoko Matsudaira Kentaro Hayakawa Fumiaki Tokimura Tsuyoshi Miyazaki Department of Orthopaedic Surgery Tokyo Metropolitan Institute for Geriatrics and Gerontology Tokyo Japan

Background: The incidence of femoral intertrochanteric fractures in older adults is higher than that of femoral neck fractures;however, both conditions are often analyzed together as proximal femoral fractures. Considering the difference in treatment, postoperative complication, and mortality risk, these two fractures should be analyzed separately. This study aimed to analyze 1-year mortality and its risk factors in patients with surgically treated femoral intertrochanteric fractures. Methods: Consecutive patients with intertrochanteric fractures who underwent surgical interventions at our institution between January 2017 and December 2021 were retrospectively reviewed. A total of 238 patients were eligible for inclusion in this study. Patients’ demographic and clinical information were retrospectively collected. Patients were divided into the 1-year mortality (n = 16) and survival (n = 222) groups. The incidence of 1-year mortality and its independent risk factors were investigated using univariate and multivariate logistic regression analyses. Results: The mean age of patients was 85.6 ± 8.5 years. The 1-year mortality rate was 6.7% (16/238). Preoperative albumin level, the Geriatric Nutritional Risk Index (GNRI), and malnutrition status (GNRI p = 0.02, p = 0.02, and p = 0.0011, respectively). Multivariate analysis showed that malnutrition status (GNRI p = 0.035) was an independent risk factor for 1-year mortality. Conclusion: Malnutrition status assessed using GNRI (GNRI < 92) was an independent risk factor for 1-year mortality. Our findings suggest that GNRI may be an effective screening tool for predicting postoperative 1-year mortality of patients with surgically treated femoral intertrochanteric fractures.

How to Transmit Disaster Information Effectively:A Linguistic Perspective on Japan’s Tsunami Warnings and Evacuation Instructions

引用

International Journal of Disaster Risk Science 2013年第3期4卷 150-158页

作者： kyoko Arai Faculty of Business Administration Toyo UniversityTokyo 112-8606Japan

When the disastrous tsunamis hit East Japan on 11 March 2011, the hi-tech information transmission system that is the pride of Japan was unable to send out the Tsunami Warnings effectively;many lives were lost as a result. Subsequently, the Japan Meteorological Agency(JMA) set up a committee of experts to improve the overall system. Last year as a result of their meetings, a report on The Improvement of the Information Text for the Tsunami Warnings was announced. The changes are, however, problematic from the linguistics perspective as the committee did not include any experts in the field. This study examines a range of recordings of the Tsunami Warnings and the Evacuation Instructionsi given for the East Japan tsunami disaster from the perspective of linguistics, especially pragmatics, whose main objective is to discover how recipients interpret verbal messages. The aim of this article is to propose further improvement to the transmission system of Tsunami Warnings and Evacuation Instructions. This study also emphasizes the necessity and importance of reexamining the overall disaster information transmission issue in Japan, from the linguistics perspective.

Reproducibility and Validity of a Chinese Food Frequency Questionnaire

引用

Biomedical and Environmental Sciences 2010年第S1期23卷 1-38页

作者： Water WILLETT kyoko HASEGAWA Department of Nutrition Harvard School of Public Health Kagawa Nutrition University

Objectives This study was design to develop a semi-quantitative Chinese Food Frequency Questionnaire （FFQ） and to conduct a validation study for the questionnaire. Methods Based on the survey experience in recent years, a new Chinese food frequency questionnaire （FFQ） with 149 items in 17 food categories was developed. A validation study on this new FFQ was conducted in Jiangsu and Beijing of China between 1999 and 2001. The period of study covered 1 year and the FFQ was validated by comparing with data obtained by a six repeated 24-hour recalls for 3 consecutive days, or a totally 18-day 24- hour recall throughout the year. A total of 271 healthy adult subjects were enrolled in the study. Food and nutrient intakes measured by the 18-day dietary recalls and food frequency questionnaires （FFQs） were computed in the National Institute for Nutrition and Food Safety, China CDC using the existing nutrition database. The average daily intake of foods and nutrients over the 18-day recall was used to compare with FFQ1 and FFQ2, which was conducted at the beginning and the end of the year, respectively. All statistical analyses were carried out using SAS software version 6.12.

Human PIWI(HIWI) is an azoospermia factor

引用

Science China(Life Sciences) 2018年第3期61卷 348-350页

作者： Hidetoshi Hasuwa kyoko Ishino Haruhiko Siomi Department of Molecular Biology Keio University School of Medicine

Transposable elements （TEs） make up nearly half of the mammalian genome. Recent probabilistic re-annotation of genome sequences indicated that as much as two-thirds or more of the human genome may be derived from TEs （de Koning et al., 2011）. Their ability to mobilize in the genome represents a constant threat to the host by creating insertion mutations, which may lead to progressive deterioration of genetic information. To counteract this threat, host cells have evolved adaptive control mechanisms to repress the activity of TEs. One such mechanism is the P1WI-piRNA pathway conserved in animals, from C. elegans to humans （Iwasaki et al., 2015）. The pathway is a germline-specific mechanism required to maintain genome integrity. In this pathway, piRNAs （short for PIWI-interacting RNAs） with 25-35 nucleotides （nt） in length form effector complexes or RNA-induced silencing complexes （RISCs） with PIWI clade proteins of Argonautes to trigger multiple forms of sequence-specific gene silencing by guiding RISCs to target RNAs by means of Watson-Crick base-pairing, piR- NA-loaded RISCs or piRISCs normally repress TEs either by cleaving their transcripts in the cytoplasm or by inducing heterochromatin formation at their insertion sites of the ge- nome.

Evaluation of a Recombinant Measles Virus as the Expression Vector of Hepatitis C Virus Envelope Proteins

引用

World Journal of Vaccines 2011年第3期1卷 98-103页

Measles virus (MV) is a negative strand RNA virus of the family Paramyxoviridae, and the attenuated Edmonston-B strain can be engineered by the reverse genetics system. Here we constructed the recombinant Edmonston strain of measles virus (MV-Ed) that expressed hepatitis C virus (HCV) envelope proteins (rMV-E1E2). The rMV-E1E2 successfully expressed HCV E1 and E2 proteins. To evaluate its immunogenicity, NOD/Scid/Jak3null mice that were engrafted with human peripheral blood mononuclear cells (huPBMC-NOJ) were infected with this rMV-E1E2. Although human lymphocytes could be isolated from the spleens of mock-infected mice during the 2-weeks-long experiment, the proportion of mice that were infected with MV or rMV-E1E2 was decreased in a viral dose-dependent manner. Over 103 PFU of virus infection decreased the human PBL to less than 5%. Significant decrease of B cell population in human PBL from rMV-E1E2 infected NOD-SCID mice and decrease of T cell population in those from MV infected mice were observed. Human antibody production in these mice was also examined. Thus, the results in this study may contribute for future improvement of recombinant vaccine using measles virus vector.
