This study was conducted to clarify the benefits of using cervical cytological examinations and human papilloma virus (HPV) testing in our cervical cancer screening program, which was carried out during the period from April 2012 through March 2013 in the Yuri-Honjo district of Akita Prefecture. A total of 772 women underwent this screening. About 11.3% (87/772) of the examinees tested positive for HPV, and of these 87 women, 64 were also positive for HPV DNA in the examinations subsequently conducted in the outpatient clinic. Of the HPV DNA-positive women who showed no sign of abnormalities in cytology, 67.6% had lesions cervical intraepithelial neoplasia (CIN) 1 and above, and five women had l CIN 2/3. Compared with the conventional cytology which detected nine women with CIN 2/3, our screening method with a combination of cytology and HPV testing found 14 women with CIN 2 or 3. To upgrade the cervical cancer screening, we recommend HPV testing should be used in combination with cervical cytology.

A study was conducted to clarify the effect of hyperoxia (HO) on exercise tolerance andhemodynamics in patients with ischemic heart disease (IHD) . The subjects were 10 patients with serious IHD who showed ischemic ST depression during low-intensity exercise testing. In all subjects, cardiopulmonary exercise testing (CPX) was performed using two types of inhalation : normoxia (NO) and HO (O2: 60%, N2: 40%) . Heart rate (HR), blood pressure (BP), rating of perceived exertion (RPE), elapsed exercise duration and pressure rate product (PRP) were measured, and ECG was recorded during CPX according to the Bruce protocol. The peak oxygen uptake (VO2peak) was calculated using the appropriate formula. These data were compared between the NO and HO groups, and the following results were obtained.
ST depressions on ECG, BP, HR and PRP after 20 min of rest showed no changes under NO. The other hand, only ST depression was improved after 20 min of rest under HO. The exercise duration in HO group was longer than in the NO group, and the VO2peak in the HO group was higher than in the NO group. However, peak RPE showed no significant difference between the HO and NO groups. The incidence of ST depression as an endpoint of CPX showed no significant difference between the two groups. BP, HR and PRP at the CPX endpoint showed no significant differences between the HO and NO groups. In patients whose exercise duration was prolonged beyond the mean value by HO, peak HR and PRP were increased significantly. However, this tendency was not seen in patients whose exercise was prolonged for less than the mean value.
In conclusion, these results suggest that an increase in the oxygen supply to peripheral working muscles may play an important role in increasing exercise tolerance under HO in IHD patients.

OBJECTIVES: Self-adhesive resin cements contain functional monomers that enable them to adhere to the tooth structure without a separate adhesive or etchant. One of the most stable functional monomers used for chemical bonding to calcium in hydroxyapatite is 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP). The aim of this study was to evaluate the influence of the10-MDP concentration on the bond strength and physical properties of self-adhesive resin cements. MATERIALS AND METHODS: We used experimental resin cements containing 3 different concentrations of 10-MDP: 3.3 wt% (RC1), 6.6 wt% (RC2), or 9.9 wt% (RC3). The micro-tensile bond strength of each resin cement to dentin and a hybrid resin block (Estenia C&B, Kuraray Noritake Dental) was measured, and the fractured surface morphology was analyzed. Further, the flexural strength of the resin cements was measured using the three-point bending test. The water sorption and solubility of the cements following 30 days of immersion in water were measured. RESULTS: The bond strength of RC2 was significantly higher than that of RC1. There was no significant difference between the bond strength of RC2 and that of RC3. The water sorption of RC3 was higher than that of any other cement. There were no significant differences in the three-point bending strength or water solubility among all three types of cements. CONCLUSIONS: Within the limitations of this study, it is suggested that 6.6 wt% 10-MDP showed superior properties than 3.3 wt% or 9.9 wt% 10-MDP in self-adhesive resin cement.

PURPOSE: The aim of this study was to evaluate the validity and reliability of the Seattle Angina Questionnaire, Japanese version (SAQ-J) as a disease-specific health outcome scale in patients with coronary artery disease. METHODS: Patients with coronary artery disease were recruited from a university hospital in Tokyo. The patients completed self-administered questionnaires, and medical information was obtained from the subjects' medical records. Face validity, concurrent validity evaluated using Short Form 36 (SF-36), known group differences, internal consistency, and test-retest reliability were statistically analyzed. RESULTS: A total of 354 patients gave informed consent, and 331 of them responded (93.5%). The concurrent validity was mostly supported by the pattern of association between SAQ-J and SF-36. The patients without chest symptoms showed significantly higher SAQ-J scores than did the patients with chest symptoms in 4 domains. Cronbach's alpha ranged from .51 to .96, meaning that internal consistency was confirmed to a certain extent. The intraclass correlation coefficient of most domains was higher than the recommended value of 0.70. The weighted kappa ranged from .24 to .57, and it was greater than .4 for 14 of the 19 items. CONCLUSIONS: The SAQ-J could be a valid and reliable disease-specific scale in some part for measuring health outcomes in patients with coronary artery disease, and requires cautious use.

We have conducted an active learning session for participants in various fields using a scenario in which university students encountered a great earthquake during a field trip. The program was unique because it not only gave participants an opportunity to simulate providing support, it also allowed them to simulate receiving support.

Objective This study aimed to identify the types, frequency, and clinical significance of altered interpreta-tion in clinical settings.Methods Routine outpatient encounters involving Portuguese-speaking Brazilian patients, Japanese doctors, and hospital-provided interpreters were digitally recorded and transcribed. Segments of consecutively interpreted utterances were coded as “altered,” in which the interpreter changed the meaning of the source utterance, or “unaltered (accurate),” and the types and frequency of occurrence were analyzed. Altered interpretations were categorized as clinically negative or positive and classified into four categories: omission, addition, substitution, or voluntary intervention. Incidents resulting from alterations were investigated. Reliability was assessed by examining the correlation between random independently coded samples.Results In total, 111 encounters were analyzed. The mean segments per encounter was 67.9 (range 14-186), and the mean frequency (standard deviation) of altered interpretations per 100 segments was 46.7 (14.3) for accurate interpretations; 46.1 (17.9) for negative or not significant alterations, including 27.2 (10.3) for omissions, 6.0 (5.0) for additions, 10.4 (6.9) for substitutions, and 2.5 (2.7) for voluntary interventions; 0.0 (0.2) for alterations potentially leading to an incident; and 26.2 (11.9) for positive alterations, including 1.8 (2.6) for positive omissions, 7.7 (4.7) for positive additions, 7.8 (6.3) for positive substitutions, and 8.8 (5.2) for positive voluntary interventions. The frequency of negative alterations was weakly negatively correlated with number of segments per minute (r=−0.339). Conclusion Trained healthcare interpreters with fewer clinically significant altered interpretations were effective. Professional medical providers should recognize the importance of positive alterations by healthcare interpreters and collaborate with them to provide safe medical care for foreign patients. To facilitate the provision of appropriate medical care to a growing foreign population with diverse cultural and linguistic needs, undergraduate medical education should teach aspiring medical professionals how to collaborate with healthcare interpreters and foreign patients.
