BackgroundCommunity-based education has been introduced in many medical schools around the globe, but evaluation of instructional quality has remained a critical issue. Community-based education is an approach that aims to prepare students for future professional work at the community level. Instructional quality should be measured based on a program's outcomes. However, the association between learning activities and students' attitudes is unknown. The purpose of this study was to clarify what learning activities affect students' attitudes toward community health care.MethodsFrom 2003 to 2009, self-administered pre- and post-questionnaire surveys were given to 693 fifth-year medical students taking a 2-week clinical clerkship. Main items measured were student attitudes, which were: "I think practicing community health care is worthwhile" ("worthwhile") and "I am confident about practicing community health care" ("confidence") using a visual analogue scale (0-100). Other items were gender, training setting, and learning activities. We analyzed the difference in attitudes before and after the clerkships by paired t test and the factors associated with a positive change in attitude by logistic regression analysis.ResultsSix hundred forty-five students (93.1%), 494 (76.6%) male and 151(23.4%) female, completed the pre- and post-questionnaires. The VAS scores of the students' attitudes for "worthwhile" and "confidence" after the clerkship were 80.2 ± 17.4 and 57.3 ± 20.1, respectively. Both of the scores increased after the clerkship. Using multivariate logistic regression analysis, "health education" was associated with a positive change for both attitudes of "worthwhile" (adjusted RR: 1.71, 95% CI: 1.10-2.66) and "confidence" (1.56, 1.08-2.25).ConclusionsCommunity-based education motivates students to practice community health care. In addition, their motivation is increased by the health education activity. Participating in this activity probably produces a positive effect and improves the instructional quality of the program based on its outcomes.

In addition to the rural background of physicians, some undergraduate and postgraduate factors were independently associated with the intention to continue a rural career.

To investigate nationwide the prevalence of hepatitis E virus (HEV) infection in the general population of Japan, serum samples were collected from 22,027 individuals (9,686 males and 12,341 females; age, mean +/- standard deviation: 56.8 +/- 16.7 years; range: 20-108 years) who lived in 30 prefectures located in Hokkaido, mainland Honshu, Shikoku, and Kyushu of Japan and underwent health check-ups during 2002-2007, and were tested for the presence of IgG, IgM, and IgA classes of antibodies to HEV (anti-HEV) by in-house ELISA and HEV RNA by nested RT-PCR. Overall, 1,167 individuals (5.3%) were positive for anti-HEV IgG, including 753 males (7.8%) and 414 females (3.4%), the difference being statistically significant (P < 0.0001). The prevalence of anti-HEV IgG generally increased with age and was significantly higher among individuals aged >or=50 years than among those aged <50 years (6.6% vs. 2.7%, P < 0.0001). Although 13 individuals with anti-HEV IgG also had anti-HEV IgM and/or anti-HEV IgA, none of them had detectable HEV RNA. The presence of HEV RNA was further tested in 50 or 49-sample minipools of sera from the remaining 22,014 individuals, and three individuals without anti-HEV antibodies tested positive for HEV RNA. The HEV isolates obtained from the three viremic individuals segregated into genotype 3 and were closest to Japan-indigenous HEV strains. When stratified by geographic region, the prevalence of anti-HEV IgG as well as the prevalence of HEV RNA or anti-HEV IgM and/or anti-HEV IgA was significantly higher in northern Japan than in southern Japan (6.7% vs. 3.2%, P < 0.0001; 0.11% vs. 0.01%, P = 0.0056; respectively).

Objective While much attention is given to the fifth vital sign, the utility of the 4 classic vital signs (blood pressure, respiratory rate, body temperature, and heart rate) has been neglected. The aim of this study was to assess a possible association between vital signs and the Sequential Organ Failure Assessment (SOFA) score in patients with sepsis. Methods We performed a prospective, observational study of 206 patients with sepsis. Blood pressure, respiratory rate, body temperature, and heart rate were measured on arrival at the hospital. The SOFA score was also determined on the day of admission. Results Bivariate correlation analysis showed that all of the vital signs were correlated with the SOFA score. Multiple regression analysis indicated that decreased values of systolic blood pressure (multivariate regression coefficient [Coef] = -0.030, 95% confidence interval [CI] = -0.046 to -0.013) and diastolic blood pressure (Coef = -0.045, 95% CI = -0.070 to -0.019), increased respiratory rate (Coef = 0.176, 95% CI = 0.112 to 0.240), and increased shock index (Coef = 4.232, 95% CI = 2.401 to 6.062) significantly influenced the SOFA score. Conclusion Increased respiratory rate and shock index were significantly correlated with disease severity in patients with sepsis. Evaluation of these signs may therefore improve early identification of severely ill patients at triage, allowing more aggressive and timely interventions to improve the prognosis of these patients.

Table 1 Distribution of survey subjects by happiness, by age and sex CI indicates cofidence interval. and Background Factors in Community-Dwelling Older Persons Ryuichi Kawamoto1), Takaaki Doi1), Akihiro Yamada1), Masanobu Okayama2), Kouki Tsuruoka2), Motomi Satho3) and Eiji Kajii2) In order to maintain and improve mental health of elderly people living in the community, a cross sectional survey was conducted to elucidate their happiness and background factors. The subjects were elderly persons living in the community who were able to fill in the questionnaire themselves. The study employed the self-recording questionnaire forms used in Kahoku Longitudinal Aging Study by Matsubayashi et al. Happiness was assessed using a visual analogue scale. Out of 2,379 elderly persons who were able to fill in the questionnaire by themselves in 2,361 (99.2%) returned the questionnaire sheets. After removing inadequate responses, analysis was possible for 1,873 (78.7%) (860 men (average age 72.7 years) and 1,013 women (average age 72.8 years)). Among those with greater happiness, the ratio of those living with others (p= 0.0051) was high, as well as those with spouses (p=0.0240), without a history of hypertension (p=0.0096) and apoplexy (p=0.0039), not receiving medication regularly (p=0.0039), with regular habit of walking (p<0.001), or with work (p< 0.001). As for the relationship between happiness and various scores, the higher the happiness scale became, the scores for ADL, information-related function, functional and emotional support network, healthy condition, appetite condition, sleep condition, memory condition, family relationships, friendship, economic condition became significantly higner (p<0.001, respectively). On multiple regression analysis using the background factors for happiness as explanatory variables, factors such as functional support network (p<0.001), emotional support network (p=0.0254), healthy condition (p<0.001), good memory condition (p=0.0027), friendship (p<0.001), good economic condition (p<0.001) were significant independent contributing factors. As for the relation between SDS and happiness, the more serious the SDS score (higher score) became, the scores for the feeling of happiness became significantly smaller (p<0.001). For amelioration of the happiness of elderly persons living in the community, attempts should be made to improve the background factors clarified by the present study by efficiently utilizing health, medical and welfare services.
