Implantation of rhBMP-2/PGS enhances bone formation and connective tissue attachment in horizontal circumferential defects. In addition, the use of a spacer membrane reduces the degree of bone formation, but minimizes ankylosis.

Aims:In obesity, fatty acid composition is altered with reduced docosahexaenoic acid (DHA) levels. Desaturating enzymes, stearoyl-CoA desaturase (SCD), delta-6 desaturase (D6D) and delta-5 desaturase (D5D) modulate fatty acid composition and are thus associated with the development of metabolic syndrome. The aim of this study was to identify the relationships among DHA content, desaturase indices and the components of metabolic syndrome in childhood obesity. Methods: Thirty-two obese children (27 male, 5 female) aged 12.0 2.6 years (mean SD), with a relative body weight greater than 120% of the standard weight for sex, age and height, were recruited. Fatty acid composition of plasma phospholipids was analyzed by gas chromatography, and the desaturase indices were assessed: SCD (

ObjectiveWe aimed to evaluate a foot-care awareness program designed to improve foot morphology, physical functioning, and fall prevention among the community-dwelling elderly. Eleven independent community-dwelling elderly women (aged 61–83 years) were provided with foot-care advice and shown effective foot-care techniques to perform regularly for 6 months, and compared with a control group of 10 elderly women who did not receive any intervention. Measurements of foot form, functional capacity, subjective foot movement, and physical function were taken at baseline and 6-month follow-up.ResultsAt follow-up, improvements were seen in the intervention group in foot morphology, subjective foot movement, foot pressure, and balance. In the intervention group, 90% of women had maintained or improved foot form and none of them had fallen during the post-intervention period, compared to the control group where 30% improved foot form (p = 0.0075) and four (40%) of them had fallen. Therefore, a foot-care program may have the potential to prevent falls and improve mobility among the elderly. Trial Registration UMIN-CTR No. UMIN000029632.

BackgroundAlthough the number of elderly people needing care is increasing rapidly in the home setting in Japan, family size and ability to provide such support are declining. The purpose of this study was to identify the risk factors of functional disability by household composition among community-dwelling elderly people.MethodsA total of 1347 elderly people aged 70 years and over participated in a baseline geriatric health examination for this prospective cohort study. In the health examination, we conducted an interview survey using a questionnaire in July 2004 and July 2005. Questionnaire items covered the following: age, sex, household, medical history, instrumental activities of daily living, intellectual activity, social role, Motor Fitness Scale, falls experienced during the past year, Dietary Variety Score, frequency of going outdoors, cognitive impairment, and depressive status. We defined the occurrence of functional disability as certification for long-term care needs of the subjects. The certification process started with a home visit for an initial assessment to evaluate nursing care needs using a questionnaire on current physical and mental status. The onset of functional disability was followed from July 2004 to March 2011. Cox proportional hazard regression analysis was used to estimate the risk factors related to the onset of functional disability, adjusted for age and sex.ResultsOf the 1084 participants, 433 were male (39.9%), and the average age was 77.8 (standard deviation, 5.4). Up to March 2011, functional disabilities occurred in 226 participants (20.9%). Elderly people living only with their children demonstrated a significantly higher risk for functional disability than the three-generation household group (hazard ratio, 1.61; 95% confidence interval, 1.08–2.40). The risk factors for functional disability varied according to household group.ConclusionsIn Japan, the number of vulnerable households with elderly people in need of care has increased steadily over the years. Appropriately identifying the risks related to functional disability requires a means of assessment that takes the household composition into consideration.

Three dimensional microporous polymers of Rh fumarate or Rh terephthalate complexes exhibited high catalytic activity for hydrogen exchange and hydrogenation of olefins at 200 K. The hydrogen exchange reaction takes place only inside the nanopores of the complexes without complete scission of C–H bond of olefin molecule.

The purpose of this study was to determine social support as a predictor of health status among older adults living alone, based on a 2-year longitudinal study in a rural area of Japan. The self-reported questionnaires were distributed to 624 older adults living alone and were collected during home visits by welfare commissioners as baseline survey. After the follow-up survey of 493 respondents as the baseline survey, we analyzed 340 persons who lived alone over the last 2 years. Women had significantly higher emotional and instrumental support scores than men. Receiving positive support from the neighborhood had a significant effect on retaining activities of daily living for older women living alone. Our results suggest that receiving social support from the neighborhood brought an improvement in the health status of older adults, particularly women living alone.

The aim of this study was to investigate the effect of the pore characteristics of β-tricalcium phosphate (β-TCP) on periodontal healing in class III furcation defects in dogs. Two types of β-TCP were prepared for grafting; 1) a tunnel pipe structure with an inner diameter of 300 μm, and 2) continuous pore structure with interconnected macropores. The furcations of thirty mandibular premolar teeth were implanted with each type of β-TCP or were left untreated as control. The dogs were sacrifi ced 8 weeks post-surgery, and healing was evaluated histologically. Downgrowth of junctional epithelium in the tunnel structure group was signifi cantly less than that in the other two groups (p<0.01). There was signifi cantly more new bone formation and new cementum formation in the tunnel structure group than that in the other two groups (p<0.01). These fi ndings suggested that β-TCP with a tunnel pipe structure promotes periodontal healing in class III furcation defects.
