We worked out TTR values in patients receiving warfarin treatment in Abashiri-Kosei General Hospital. The patients were divided into two groups - those with satisfactory TTR values and those with poor TTR values - and associations between patient factors and average dosing interval were examined in the two groups. A total of 178 patients joined this study. The average TTR value worked out at 65.1±24.8%. It was found that the average TTR value for those patients aged at 70 and above came to 72.7±21.4%, which was significantly high as compared with 51.06plusmn;24.6% for those under 70 years of age. When the average TTR value was calculated after the optimal PT-range for the group of those below the age of 70 was changed from 2.0～3.0 to 1.6～2.6, it rose from 51.0% to 74.9%. These findings made it clear that PT-INR, regardless of age, was under control within the range from 1.6 to 2.6 in this hospital in accordance with the results of the J-RHYTHM Registry analysis.

Although identification of water contact patterns is one of the most important factors for the prevention of Schistosoma japonicum infection, it is still insufficient for clarifying specific high-risk behaviors and their implications. Parasitological studies and behavioral observations were carried out in a rural village, the Dongting Lake region, China. A time-allocation study conducted by a time-saving spot-check method was implemented to quantify the behavioral risks. Of the 122 participants, 18 (14.8%; 95% confidence interval: 8.5, 21.0) were positive for S. japonicum. Among those diagnosed, the median (25−75% quartile) eggs per gram was 8 (8−16). A significant positive correlation with worm intensity was found among people who repair ships on the marshland (p&It;0.001), and this potential risk was consistent with previous suggestions. Although the parasitological techniques and study design require further improvements, our observational methods may be of use to explicitly identify behaviors at the local level that could be relevant to prevention.

A 61-year-old man was referred to our hospital for treatment of hemolytic anemia after ascending aortic replacement aortic dissection. Cine mode magnetic resonance imaging (MRI) showed stenosis at the proximal anastomostic site of a Teflon strip. We diagnosed hemolytic anemia induced by collision of red blood cells on the inverted felt strip. Conservative therapy with Sarpogrelate and β-blockers was effective to treat his hemolytic anemia. However, 7 years later he was re-admitted because of infective endocarditis at the aortic valve, and underwent aortic root replacement. Intraoperative findings showed a stiff and inverted Teflon felt strip causing stenosis of the proximal anastomosis. Hemolytic anemia should be considered a rare complication of using a Teflon felt strip to reinforce anastomosis for acute aortic dissection.

OBJECTIVESOur objectives were (1) to evaluate whether single spot urine is suitable media for longer-term phthalate esters exposure assessment, and (2) to estimate intake level of phthalate esters of Japanese pregnant women using urinary metabolites as an indicator of prenatal exposure level in their offspring.

METHODSWe analyzed nine metabolites (MMP, MEP, MnBP, MBzP, MEHP, MEOHP, MEHHP, MINP, MnOP) of seven phthalate esters in spot urine samples from 50 pregnant women by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Using four urine samples collected from each of 12 subjects from 50 pregnant women within 5-12 weeks, we compared intra- and interindividual variation in urinary metabolites by calculation of intraclass correlation coefficient (ICC). We estimated daily intakes of 50 pregnant women from their urinary metabolite concentrations.

RESULTSICCs for seven phthalate metabolite concentrations in single spot urine samples were: MMP (0.57), MEP (0.47), MnBP (0.69), MBzP (0.28), MEHP (0.51), MEHHP (0.43), and MEOHP (0.41) in 12 pregnant women. Phthalate ester metabolites had high detection rates in 50 subjects. The mean daily intake ranged from 0.01 to 2 mug/kg per day. The daily intake levels in all subjects were lower than corresponding tolerable daily intake (TDI) set by the European Food Safety Authority (EFSA), though maximum value for DnBP of 6.91 mug/kg per day accounted for 70% of TDI value.

CONCLUSIONSHigher ICCs indicated that phthalate metabolite levels in single spot urine could reflect longer-term exposure to the corresponding diesters of subjects. Although the current exposure level was less than TDIs, further studies and exposure monitoring are needed to reveal the toxicity of phthalate esters to sensitive subpopulation.

The purpose of this research was to develop a reflection program to support the practice of end-of-life care for nurses and to examine its effectiveness and feasibility. We developed and examined the effectiveness of a facilitator-based reflection program (FRP) and card-based reflection program (CRP). Average scores for both the FRP and CRP were measured using a Knowledge, Attitude and Difficulty Scale for palliative care and Self-education Ability Scale implemented before, immediately after, and 3 months after the program. The changes in scores were compared. This research was conducted with approval from the ethics review committee. Nine people participated in the FRP, and 15 in the CRP. FRP significantly reduced difficulty concerning palliative care compared to CRP. FRP significantly increased knowledge compared to CRP. Similar results were obtained within the FRP group. Both FRP and CRP were considered highly feasible because the program evaluation was high. In the future, it is necessary to clarify the effect of the reflection program by reviewing the research design.

BACKGROUND: Previous studies have suggested that exposures to heavy metals (arsenic, cadmium, lead, and selenium) may be associated with differences in blood pressure. However, the findings of these studies have been inconsistent. This study was performed to examine the associations between urinary heavy metal concentrations and blood pressure among residents of four Asian countries (Bangladesh, Indonesia, Nepal, and Vietnam). METHODS: This cross-sectional study examined 1899 adults in four Asian countries. Urinary concentrations of heavy metals were measured by inductively coupled plasma mass spectrometry. A questionnaire survey was administered regarding individual characteristics. Anthropometric measurements (height and weight) were performed. Systolic and diastolic blood pressures were measured after a short rest. Multiple linear regression models were applied to investigate associations between urinary heavy metal concentrations and blood pressure after adjustments for age, sex, and body mass index. RESULTS: The geometric means of the urinary concentrations of arsenic, cadmium, lead, and selenium were 84.6, 0.885, 2.09, and 16.5 μg/g creatinine, respectively. The urinary arsenic concentrations were slightly higher than those typically reported in non-polluted populations, while urinary cadmium, lead, and selenium concentrations were equivalent or slightly lower. The urinary lead concentrations were positively associated with both systolic and diastolic blood pressure, but urinary selenium concentrations were negatively associated with them. CONCLUSIONS Variations in the urinary concentrations of lead and selenium were associated with blood pressure at low levels of exposure/intake.
