Relationship of living arrangement with the decline in functional capacity in elderly people by gender: a longitudinal observational study.

BACKGROUND: The living arrangement has been suggested as an important factor affecting health. Recent studies have also suggested that there was a risk among elderly persons who were not alone. This study examined whether the detailed living arrangement was associated with a future decline in functional capacity in the elderly, by gender, in a Japanese suburban city. METHODS: A 3-year longitudinal questionnaire survey (baseline: 2011; follow-up: 2014) for aged 65 years or older was conducted in Kurihara city, Japan. Of the respondents in the baseline survey, we analyzed those who scored 13 points (a perfect score which indicates the highest functional capacity; n = 2627) on the Tokyo Metropolitan Institute of Gerontology Index of Competence at the baseline. The exposure was living arrangement at baseline, divided into five categories: "with spouse only," "living alone," "with child and his/her spouse," "with child without his/her spouse," and "with other family/person." The outcome was the decline in functional capacity at the follow-up survey (score decreased to 10 points or less from 13 points). RESULTS: Of the 2627 analyzed population, 1199 (45.6%) were men. The incidence of the decline was 5.8% in men and 5.9% in women. Multivariable logistic regression analyses adjusted for age, educational attainment, and health behavior and condition revealed that in women, the odds ratio of the decline was higher in living with child and his/her spouse (2.41, 95% confidence interval; 1.10-5.28) referring to living with spouse only. When adjusting activities inside and outside the home such as housework additionally, the association was attenuated to marginal significance (2.25, 0.98-5.18). No statistical significance was observed in men. CONCLUSIONS: These results suggested that living with child and spouse of a child was associated with the future decline in women's functional capacity.

Identification of loci associated with embryo yield in microspore culture of Brassica rapa by segregation distortion analysis.

KEY MESSAGE: We identified three physical positions associated with embryo yield in microspore culture of Brassica rapa by segregation distortion analysis. We also confirmed their genetic effects on the embryo yield. Isolated microspore culture is well utilized for the production of haploid or doubled-haploid plants in Brassica crops. Brassica rapa cv. 'Ho Mei' is one of the most excellent cultivars in embryo yield of microspore culture. To identify the loci associated with microspore embryogenesis, segregation analysis of 154 DNA markers anchored to B. rapa chromosomes (A01-A10) was performed using a population of microspore-derived embryos obtained from an F1 hybrid between 'CR-Seiga', a low yield cultivar in microspore-derived embryos, and 'Ho Mei'. Three regions showing significant segregation distortion with increasing 'Ho Mei' alleles were detected on A05, A08 and A09, although these regions showed the expected Mendelian segregation ratio in an F2 population. The additive effect of alleles in these regions on embryo yield was confirmed in a BC3F1 population. One region on A08 containing Br071-5c had a higher effect than the other regions. Polymorphism of nucleotide sequences around the Br071-5c locus was investigated to find the gene possibly responsible for efficient embryogenesis from microspores.

A comparative study on the effectiveness of one-way printed communication versus videophone interactive interviews on health promotion.

INTRODUCTION: We performed a comparative study of a health education programme that was delivered either through one-way communication with printed media, or through interactive videophone interviews. We aimed to ascertain which mode of counselling, when used in combination with telemonitoring, is more effective at lifestyle modification intended to improve health status. METHODS: Participants, who were residents of Kurihara city in Miyagi prefecture, Japan, were randomized into two groups: one group received individualized monthly documented reports (n = 33; 22 females; average age: 67.2 years), and the other received interactive videophone communication (n = 35; 22 females; average age: 65.1 years) for three months. Telemonitoring was conducted on both groups, using a pedometer, weighing scale and a sphygmomanometer. Pre- and post-intervention, anthropometric measurements and blood tests were performed; the participants also completed self-administered questionnaires. RESULTS AND DISCUSSION: The two groups showed similar degrees of health status improvement and satisfaction levels. However, the participants in the videophone group were more aware of improvements in their lifestyles than were the participants in the document group. The individualized printed communication programme was less time-consuming compared to videophone communication. Further studies are needed to formulate a balanced protocol for a counselling-cum-telemonitoring programme that provides optimal health improvement and cost performance with the available human resources.

Construction of the integrated model for practical career support to the professional athletes.

Recently, along with the enhancement of the argument for career of athletes, many researchers who major in sports psychology focus mainly on athletic retirement, a coordination of transitions in sport or and outside sport, social support and professional assistance in career transition, in the context of the second career concerning to professional athletes in Japan. However, when it comes to career transition of professional athletes, it is necessary to consider "career" from the whole perspectives of human life. Therefore, the purpose of this study is to clarify the career transition of professional athletes by the way of questionnaire and interview survey, which is approached from the view point of industrial/organizational psychology. For this purpose, we implemented the interview survey to professional athletes in 2008. In addition, we carried out the investigation to professional football players (interview survey: 5 players, questionnaire survey: 102 players) in 2009. Consequently, three following findings were led in conclusion. (1)Career intervention to professional athletes should be performed before the turning point of the career (career transition). (2)It is important to assess the career intervention to professional athletes. (3)It is an important stance to watch the processes when professional athletes open up one's career by oneself.
