BackgroundIn the early stages of Pandemic (H1N1) 2009, border control measures were taken by quarantine stations to block the entry of infected individuals into Japan and community containment measures were implemented to prevent the spreading. The objectives of this study were to describe these measures and the characteristics of infected individuals, and to assess the measures' effectiveness.Methodology/Principal FindingsBorder control and community containment measures implemented from April to June (Period I: April 28–May 21, Period II: May 22–June 18) 2009 were described. Number of individuals identified and disease characteristics were analyzed. For entry screening, a health declaration form and an infrared thermoscanner were used to detect symptomatic passengers. Passengers indicated for the rapid influenza test underwent the test followed by RT-PCR. Patients positive for H1N1 were isolated, and close contacts were quarantined. Entry cards were handed out to all asymptomatic passengers informing them about how to contact a health center in case they developed symptoms. Nine individuals were identified by entry screening and 1 during quarantine to have Pandemic (H1N1) 2009. Health monitoring by health centers was performed in period I for passengers arriving from affected countries and in period II for those who had come into contact with the individuals identified by entry screening. Health monitoring identified 3 infected individuals among 129,546 in Period I and 5 among 746 in Period II. Enhanced surveillance, which included mandatory reporting of details of the infected individuals, identified 812 individuals, 141 (18%) of whom had a history of international travel. Twenty-four of these 141 passengers picked up by enhanced surveillance had been developing symptoms on entry and were missed at screening.Conclusion/SignificanceSymptomatic passengers were detected by the various entry screening measures put in place. Enhanced surveillance provided data for the improvement of public health measures in future pandemics.
Physician Job Satisfaction and WorkingConditions in Japan: Koji WADA, et al. Department of Preventive Medicine and Public Health, Kitasato University School of Medicine-Objectives: The aim of this study was to determine factors of working conditions associated with job satisfaction among physicians in Japan. Methods: We sent a questionnaire to all the physicians who graduated from a medical school in Japan. Physicians who were satisfied with their job were determined as those who selected "very satisfied" and "satisfied" in response to the question: "Overall, are you satisfied with your job?" Working conditions were determined from 10 different aspects: income fairness, hospital resources, career satisfaction, difficulty in patient care, lack of personal time, administrative work, workload, and relationships with physician colleagues, staff and patients. Logistic regression analysis was used to explore the association between working conditions and job satisfaction. Results: Among the respondents, 209 (55.4%) men and 62 (61.4%) women were determined to be satisfied with their job. Job satisfaction was associated with income fairness for both men (corrected odds ratio 1.31, 95% confidence interval 1.09 to 1.47) and women (1.35, 1.05 to 1.53). For men, job satisfaction was associated with good hospital resources (1.45, 1.29 to 1.57), high career satisfaction (1.41, 1.23 to 1.57), good relationships with physician colleagues (1.33, 1.12 to 1.49), and good relationships with hospital staff (1.28, 1.07 to 1.45). For women, job satisfaction was associated with good relationships with patients (1.41, 1.07 to 1.56). Conclusions: Certain working conditions
Field Studywere important factors for job satisfaction among physicians. These factors should be discussed for improving working conditions. (J Occup Health 2009; 51: 261-266)
BackgroundHyperuricemia is prevalent in patients with chronic kidney disease (CKD). We explored the hypothesis that asymptmatic hyperuricemia may be associated with new-onset CKD.MethodsThe participants were all male factory workers in Kanagawa, Japan (n = 1,285). All were over 40 years of age and had undergone annual health examinations from 1990 to 2007. Individuals with a history of gouty attacks were excluded from the study. A retrospective cohort study was conducted by following the estimated glomerular filtration rate (eGFR) for each participant over a maximum period of 18 years. The endpoint was new-onset CKD defined as eGFR < 60 mL/min/1.73 m2. The associations between new-onset CKD and the presence of hyperuricemia, low serum high-density lipoprotein cholesterol, hypertension, diabetes, and obesity were analyzed.ResultsThe mean (± standard deviation) follow-up period was 95.2 (± 66.7) months, and new-onset CKD was observed in 100 participants (7.8%) during this follow-up. Cox proportional hazards model revealed that the hazard ratio of new-onset CKD due to hyperuricemia, low serum high-density lipoprotein cholesterol, hypertension and obesity were 3.99 (95% confidence interval: 2.59-6.15), 1.69 (1.00-2.86), 2.00 (1.29-3.11) and 1.35 (0.87-2.10), respectively. Concerning hyperuricemia, low serum high-density lipoprotein cholesterol, hypertension and obesity, the log-rank tests showed P values of < 0.01, 0.01, < 0.01 and < 0.01, respectively.ConclusionThe results of this study suggest that asymptomatic hyperuricemia is a predictive factor for new-onset CKD for Japanese male workers.
Increased LDL-C levels are associated with the development of incident CKD and eGFR decline in young to middle-aged working men without hypertension and/or DM.
Prolonged fatigue among elementary and junior high school teachers not only damages their health but also affects the quality of education. The aim of this study was to determine the factors of working conditions associated with prolonged fatigue among teachers at public elementary and junior high schools. We distributed a self-reported, anonymous questionnaire to 3,154 teachers (1,983 in elementary schools, 1,171 in junior high schools) working in public schools in a city in Japan. They were asked to assess 18 aspects of their working conditions using a seven-point Likert scale. Prolonged fatigue was measured using the Japanese version of the checklist individual strength questionnaire. Multiple regression analysis was used to examine the association between working conditions and prolonged fatigue. Gender, age, and school type were introduced as confounders. In all, 2,167 teachers participated in this study. Results showed that qualitative and quantitative workload (time pressure due to heavy workload, interruptions, physically demanding job, extra work at home), communication with colleagues (poor communication, lack of support), and career factors (underestimation of performance by the board of education or supervisors, occupational position not reflecting training, lack of prospects for work, job insecurity) were associated with prolonged fatigue.
These findings suggest that WC > 80.0 cm is a risk factor for incident CKD and strongly associated with a decline in eGFR in the young- to middle-aged working healthy men.
Employers should take measures to improve working conditions in hospitals, and give physicians the opportunity to learn how to cope with WFC. These measures could ultimately help prevent prolonged fatigue.
