The Effects of Providing Advance Notice and Stress-Coping Traits on Physiological Stress of Patients during Dental Treatment
Patients tend to feel stress in association with dental treatment due to uneasiness and fear. We investigated the effects of providing advance notice and stress-coping traits on the physiological stress of patients during dental treatment. Sixty non-dental professionals (male, n = 26; female, n = 34; mean age, 49.9 years) were recruited for this study and informed consent was obtained. Subjects were given simulated dental treatment including thre…
Factors Affecting the Career Continuation of Newly Graduated and Reinstated Dental Hygienists Who Participated in a Technical Training Program in Japan
This study aimed to identify (1) what newly graduated dental hygienists and reinstated dental hygienists consider important for preventing early turnover in their own professions and for encouraging them to continue in the profession more generally and (2) relevant factors among hygienists intending to continue working in the field. An anonymous, self-administered questionnaire survey was distributed to 215 Japanese dental hygienists who particip…
Analysis of Incident Reports of a Dental University Hospital
Incident reports are important for improving the quality and safety of medical care. Healthcare workers with less than one year of work experience have been reported to cause the most incidents, and the most common incident is "drug-related". However, few studies have comprehensively analyzed incidents in dentistry, and the characteristics of dental incidents have not been understood. In this study, to understand the characteristics of dental inc…
Determination of Urinary Cotinine Cut-Off Concentrations for Pregnant Women in the Japan Environment and Children’s Study (Jecs)
Few studies have assessed the accuracy of self-reported questionnaires to determine smoking habits relative to urinary biomarkers. This study investigated urinary cotinine cut-off concentrations distinguishing active, passive and non-smokers among pregnant women who participated in the Japan Environment and Children's Study, a nationwide birth cohort study. Pregnant participants with measured urinary cotinine concentrations (UCCs) and who complet…
“Telling” and assent
INTRODUCTION: One of the ethical issues surrounding birth cohort studies is how to obtain informed assent from children as they grow up. What and how parents tell their children affects children's future choices about the study, yet few studies have focused on parents' influence on children. OBJECTIVE: This study examines parents' attitudes towards telling their children about their participation in a specific birth cohort study. METHODS: We cond…
Acute Effects of Ambient PM2.5 on All-Cause and Cause-Specific Emergency Ambulance Dispatches in Japan
Short-term health effects of ambient PM 2.5 have been established with numerous studies, but evidence in Asian countries is limited. This study aimed to investigate the short-term effects of PM 2.5 on acute health outcomes, particularly all-cause, cardiovascular, respiratory, cerebrovascular and neuropsychological outcomes. We utilized daily emergency ambulance dispatches (EAD) data from eight Japanese cities (2007-2011). Statistical analyses inc…
Heat-related mortality
Impact of short-term exposure to fine particulate matter on emergency ambulance dispatches in Japan
BACKGROUND: Evidence of an association between fine particulate matter (PM2.5) and morbidity is limited in Asia. We used a case-crossover design to evaluate the association between short-term exposure to PM2.5 and emergency ambulance dispatches (as a proxy of acute health outcomes), and to calculate the extent to which a 10 μg/m(3) decrease in PM2.5 concentrations would reduce the number of ambulance dispatches. METHODS: We used data on emergency…
Rationale and study design of the Japan environment and children’s study (Jecs)
Through JECS, chemical substances to which children are exposed during the fetal stage or early childhood will be identified. The JECS results will be translated to better risk assessment and management to provide healthy environment for next generations
Associations between exposure to ambient photochemical oxidants and the vitality or mental health domain of the health related quality of life
Background: Ambient air pollution may affect the health related quality of life (HRQOL) of people, as assessed by the vitality (VT) and mental health (MH) domains of the SF-36 health survey (SF-36). Methods: In a nationwide survey, 4500 people aged 20 years and older were selected from the entire population of Japan by stratified random sampling in October 2002. A total of 2896 subjects filled out the self administered questionnaire that included…
