[The number of deaths by suicide after the Great East Japan Earthquake based on demographic statistics in the coastal and non-coastal areas of Iwate, Miyagi, and Fukushima prefectures].

Objective　The number of deaths by suicide after the Great East Japan Earthquake was surveyed based on demographic statistics. In particular, this study examined whether or not there were excessive deaths due to suicide (excluding people who were injured in the earthquake) after the Great East Japan Earthquake disaster. This examination surveyed municipalities in coastal and non-coastal areas of Iwate, Miyagi, and Fukushima prefectures (referred to below as the "three prefectures").Methods　The demographic statistics questionnaire survey information supplied by Article 33 of the Statistics Act (Ministry of Health, Labour and Welfare's published statistics Vol. 0925 No.4, September 25th, 2014) were used as the basic data with particular reference to the information on the deaths from January 1st, 2010 to March 31st, 2013. The information obtained included the date of death, the municipality where the address of the deceased was registered, the gender of the deceased, age at the time of death, and cause of death codes (International Classification of Disease Codes 10th revision: ICD-10). Additionally, information was gathered about the population based on the resident register from 2009 to 2013 and the 2010 National Census; the number of deaths by suicide was then totalled by period and area. The areas were classified as municipalities within three prefectures and those located elsewhere using the municipality where the address of the deceased was registered.Results　The SMR for suicides did not show a tendency to increase for coastal or non-coastal areas throughout the two-year period after the earthquake disaster (from March 2011 to February 2013).　The SMR for the three prefectures 0-1 years after the disaster compared with the year before the disaster was 0.92 and for 1-2 years after the disaster was 0.93. Both these values were significantly low. Looking at both the non-coastal and coastal areas from each of the three prefectures, the SMR for suicides for 0-1 and 1-2 years after the disaster compared with the year before the disaster ranged from 0.73 to 1.07. None were significantly high.Conclusion　The above results indicate that there was no increase in deaths by suicide in these three prefectures in the two years following the earthquake disaster.

Vision and hearing impairments, cognitive impairment and mortality among long-term care recipients: a population-based cohort study.

BACKGROUND: Vision and hearing impairments among elders are common, and cognitive impairment is a concern. This study assessed the association of vision and hearing impairments with cognitive impairment and mortality among long-term care recipients. METHODS: Data of 1754 adults aged 65 or older were included in analysis from the Gujo City Long-Term Care Insurance Database in Japan for a mean follow-up period of 4.7 years. Trained and certified investigators assessed sensory impairments and cognitive impairment using a national assessment tool. Five-level scales were used to measure vision and hearing impairments. Cognitive performance was assessed on two dimensions, namely communication/cognition and problem behaviors. We performed logistic regression analysis to estimate odd ratios (ORs) and 95 % confidence intervals (CIs) for the association of vision and hearing impairments with cognitive impairment. Using Cox proportional hazard regression models, we obtained hazard ratios (HRs) for mortality. RESULTS: Of 1754 elders, 773 (44.0 %) had normal sensory function, 252 (14.4 %) vision impairment, 409 (23.3 %) hearing impairment, and 320 (18.2 %) dual sensory impairment. After adjusting for potential cofounders, ORs of cognitive impairment were 1.46 (95 % CI 1.07-1.98) in individuals with vision impairment, 1.47 (95 % CI 1.13-1.92) in those with hearing impairment, and 1.97 (95 % CI 1.46-2.65) in those with dual sensory impairment compared to individuals with normal sensory function. The adjusted HR of overall mortality was 1.29 (95 % CI 1.01-1.65) in individuals with dual sensory impairment and cognitive impairment relative to normal sensory and cognitive functions. CONCLUSIONS: Cognitive impairment was most common in individuals with dual sensory impairment, and those with dual sensory impairment and cognitive impairment had increased mortality.

[The relationships between public willingness to engage in cooperative childrearing and their attitudes toward cooperative childrearing, the local environment, and social capital].

OBJECTIVES: This study examines the relationship between people's willingness to cooperate with others in childrearing, and their attitudes toward such cooperation. The study also examines their thoughts about their local living environment, and their awareness of social capital in this regard. METHODS: In Study I, a questionnaire was constructed based on items derived from existing literature that examined people's willingness to cooperate with others in childrearing and their attitudes towards years, and living in A Town, were asked to fill out the questionnaire. In Study II, another questionnaire was constructed comprising 32 items derived from the questionnaire used in Study I that examined willingness to cooperate and attitudes toward cooperative childrearing. Furthermore, we added 15 items on the local living environment and 10 items on the elements constituting social capital. Three hundred and fifty-three mothers with pre-school children, 325 mothers with primary school children, and 383 women between 45 and 60 years of age, all living in the C Junior High School district in B City (a total of 1,061 respondents) completed the questionnaire. RESULTS: We conducted a factor analysis, and the following eight factors (derived from 32 items) were extracted, which related to willingness to cooperate in childrearing and attitudes toward cooperative childrearing: "It is necessary to cooperate in childrearing"; "I take care of others' children"; "I participate in festivals or local events"; "I play with children"; "Public assistance for children should be increased"; "I greet children"; "I observe people passing in front of my house"; and "I help with In Study II, we also identified a factor that influenced willingness to cooperate in childrearing and attitudes toward cooperative childrearing: mothers' and local residents' awareness of the elements constituting social capital. Particularly noteworthy in this regard were the effects of conversation, consultation, and the lending and borrowing of household items between neighbors, friends, acquaintances, and relatives. CONCLUSION: Mothers' and local residents' awareness of the elements constituting social capital was identified as a factor that influences willingness to cooperate in childrearing and attitudes toward cooperative childrearing. In particular, connections and social interaction were shown to have primary influences.

Rapid learning by walking observers wearing a reversing or inverting prism.

We measured the initial rapid learning of walking observers who wore an up-down inverting or left-right reversing prism. This prism-walking version of the 'mirror-drawing' experiment revealed that the learning curve as a function of the trial number was the same as that typically acquired from a traditional mirror-drawing experiment. We suggest that the initial short-term learning process involved in prism walking is similar to that in mirror drawing and is related to the high-level decision-making process involved in visuo-motor planning of actions with feedback from transformed vision.

[Cisplatin and S-1 combination therapy after reduction surgery for stage IV gastric cancer].

To evaluate the efficacy of cisplatin and S-1 combination therapy after reduction surgery for Stage IV gastric cancer, we retrospectively examined 73 patients with Stage IV gastric cancer who underwent gastrectomy. We classified the patients into the following four groups according to their postoperative therapies and analyzed their outcomes: A) S-1 +CDDP therapy (n=22); B) oral 5-FU therapy (n=30); C) 5-FU+CDDP therapy (n=14); and D) S-1 therapy (n= 7). The median survival time was 465 days in the S-1+CDDP therapy group, 158 days in the oral 5-FU therapy group, 332 days in the 5-FU+CDDP therapy group, and 374 days in the S-1 therapy group. The respective 2-year and 3-year survival rate was 37.8% and 20.2% in the S-1+CDDP therapy group, 3.4% and 3.4% in the oral 5-FU therapy group, 7.1% and 0% in the 5-FU+CDDP therapy group, and 0% and 0% in the S-1 therapy group, respectively. We consider that S-1+CDDP therapy after reduction surgery improves survival in patients with Stage IV gastric cancer and should be further investigated.
