Here, we report the draft genome sequence and annotation of Flavobacterium psychrophilum strain SSADA-1411. This strain was isolated from the skin ulcer of an ayu (Plecoglossus altivelis altivelis) migrating downriver to spawn in the lower Shimanto River, in western Kochi Prefecture on Shikoku Island in Japan.

The aim of this study was to evaluate the associations between dietary pattern, adiponectin and insulin resistance. The study population consisted of 612 men and women aged 35-69 years old who had participated in the baseline survey of Japan Multi-Institutional Collaborative Cohort (J-MICC) Study in Tokushima Prefecture. Diets and lifestyle related variables were assessed by questionnaires. Multiple regression analyses were used to analyse the relations between dietary patterns and high molecular weight (HMW) adiponectin. For further analysis, path analysis was used to test the hypothesised model of association between dietary pattern, serum adiponectin and insulin resistance. The result showed that higher score of bread and dairy pattern was directly associated with increased serum level of adiponectin in women, which was inversely related to homeostasis model assessment of insulin resistance (HOMA-IR). In conclusion, higher consumption of bread and dairy products, and low intake of rice may be associated with increased serum adiponectin in women.

In this paper, we describe the draft genome sequence of Flavobacterium psychrophilum strain KTEN-1510, with genotype A/G-C. This strain was isolated in October 2015 from the gills of an ayu (Plecoglossus altivelis altivelis) in the upper Kagami River in central Kochi Prefecture on Shikoku Island, Japan.

Studies on the associations of dietary Ca and vitamin D intakes with arterial stiffness are scarce. In the present study, these associations were evaluated in Japanese men. Data from a total of 535 eligible men, aged 35-69 years, who participated in the baseline survey of a cohort study in Tokushima Prefecture, Japan, and underwent brachial-ankle pulse wave velocity (ba-PWV) measurements were analysed. ba-PWV is a measure of arterial stiffness and is recognised as a marker of atherosclerotic vascular damage. Information regarding the cohort’s lifestyle characteristics including dietary behaviour over the past year was obtained from a structured self-administered questionnaire. Dietary Ca and vitamin D intakes were adjusted for total energy intake using the residual method and divided into quartiles; the highest quartile was used as the reference. General linear models were used to evaluate the associations between dietary Ca and vitamin D intakes and ba-PWV values adjusted for probable covariates. The association between dietary Ca intake and ba-PWV was further evaluated using similar general linear models stratified by dietary vitamin D intake (median or below/above median). Dietary Ca intake was found to be significantly inversely associated with ba-PWV after adjusting for probable covariates (P for trend = 0·020). However, no such association was observed between dietary vitamin D intake and ba-PWV. The inverse association between dietary Ca intake and ba-PWV was striking in subjects with higher dietary vitamin D intake. However, no association was found in subjects with lower dietary vitamin D intake. These results indicate that adequate dietary Ca and vitamin D intakes may be protective against the development of arterial stiffness in Japanese men.

Study design:Retrospective questionnaire-based epidemiological study.Background:Physicians treating acute traumatic spinal cord injury (SCI) in Japan noticed an increased occurrence of cervical SCI without skeletal injury.Objective:To elucidate the precise epidemiology of acute cervical SCI with the aim of planning a prevention program.Methods:Questionnaires were posted to all hospitals in Tokushima prefecture (around 780 000 inhabitants) to investigate the annual incidence of SCI in 2011 and 2012.Results:The response rate was 79% in 2011 and 64% in 2012. The returned questionnaires reported on 95 patients in 2011 and 91 patients in 2012, with a mean age of 67.6 and 64.3 years and an annual incidence (per million population) of 121.4 and 117.1, respectively. More than two-thirds of the cases suffered cervical SCI without skeletal injury, and 61% of these were categorized as Frankel D neurological deficits due to low-energy impact as the main cause.Conclusion:The incidence of incomplete cervical SCI does appear to be increasing, and significant regional differences in the incidence of cervical SCI exist across Japan. We speculate that factors other than age are contributing to this increase.Spinal Cord advance online publication, 11 February 2014; doi:10.1038/sc.2014.13.
