Thromboembolic events after cardiac surgery, including ischemic strokes, can be devastating complications, however only a few studies manifest the platelet activation and coagulation state after off-pump coronary artery bypass (OPCAB). Platelet-derived microparticles (PMP) are observed as released vesicles from platelets following platelet activation, and are believed to play a role in some clinical diseases because of their procoagulant activity. The aim of the present study was to evaluate the hypercoagulant state after OPCAB using PMP and other indices. Data were obtained from 15 patients (aged 69±7 years; only men) undergoing elective OPCAB surgery. One hundred milligrams of aspirin were used as postoperative antiplatelet drugs. Preoperative risk factors, operation time, postoperative hospital stay, transfusion and blood samples of CBC, PMP, βTG, PF 4, platelet aggregation, FDP, D-dimer and TAT of pre- and postoperative days (POD) 3 and 7 were studied. There was no difference between the PMP level with or without risk factor. The PMP levels of POD 3 and 7 were significantly higher compared to the preoperative levels (pre-op, POD 3, 7:9.1±5.1, 15.2±10.3, 28.4±24.5/10⁴plt respectively, p<0.05). The levels of FDP, D-dimer and TAT rose significantly on POD 3 and 7 and significantly correlated with the PMP levels. Beta TG, PF 4 and platelet aggregation did not change after OPCAB surgery, and no correlation was found with the PMP levels. Elevated levels of PMP, TAT, FDP and D-dimer persisted until POD 7 and suggested not only platelet activation, but also activation of the coagulation and fibrinolytic system. The findings suggest that 100mg of aspirin may not be adequate for the inhibition of platelet activation after OPCAB surgery.

A 64-year-old woman who had been followed for complete right bundle branch block at another hospital was found to have heart failure due to cardiac sarcoidosis. She was admitted because of progressive thinning of the ventricular septum and septal aneurysm which protruded into the right ventricle. On echocardiogram, her left ventricular ejection fraction had decreased to 40%. We decided to perform an operation because the patients's heart failure was thought to be due to dyskinesia of the ventricular septum with bulging of the septum into the right ventricle during systole, which consequently decreased cardiac output. The scarred ventricular septum, which was observed through right atrial, right ventricular and aortic incisions, was incised along the marginal normal interventricular myocardium. A tailored 4×3 cm oval Dacron patch was secured over this opening. A DDD pacemaker was implanted for complete atrio-ventricular block and, to synchronize both ventricles, ventricular leads were fixed on the right and left ventricular epicardium. Her postoperative course was uneventful. A postoperative pathologic study revealed a noncaseating granuloma on the border of the normal myocardium. We report a rare surgically treated case of cardiac sarcoidosis.

A 52 year-old man was admitted to our institution with sudden onset of severe chest and back pain. The electrocardiogram showed ST segment depression in leads I, II, aVL, aVF, V3-6. Emergent coronary angiogram was performed, but the catheter did not reach to the coronary ostia, and it only performed false lumen aortogram. Computed tomography showed acute Stanford A aortic dissection. Ultrasound echocardiography also showed aortic regurgitation 3/4 degree. We decided to perform an emergency operation. During anesthesia induction, systemic blood pressure fell below 80 mmHg during systolic period, and pulmonary pressure raised to 60 mmHg. Transesophageal echography showed the movements of dissection flap intermittently obstructed the coronary blood flow and aortic valve annuls. Those flap movements, so called ‘flap suffocation’ was thought to be the cause of cardiac failure. Intra-operative findings of the ascending aorta showed an entry of dissection just above the left coronary ostia, and the entire detachment of intima to aortic wall. We performed ascending aorta replacement with aortic valve resuspension and fixation of coronary ostia. The postoperative course was uneventful, and he was discharged on the 25th postoperative day. For the precise treatment of acute Stanford A aortic dissection with such coronary ischemia, quick diagnosis and operative correction is essential.

To evaluate the educational effects of a lung-sound auscultation simulator, “Mr. Lung”, we compared outcomes of fifth-year medical students in 2001 and 2002. From June 2001 through March 2002, we used “Mr. Lung” for small-group teaching for 100 fifth-year medical students. The following year, we opened our laboratory so that the fifth-year students could study with “Mr. Lung” by themselves for 1 month. “Mr. Lung” was then used for objective structured clinical examinations in May 2002. From June 2002 through April 2003, we used “Mr. Lung” again for small-group teaching for 91 fifth-year students. The class consisted of 90 minutes' training for the auscultation of lung sounds. At the beginning of class, auscultation tests were performed in which the students listened through their stethoscopes to 3 examples of abnormal lung sounds on “Mr. Lung” and answered questions about the location and quality of the sounds. The percentages of correct answers in 2001 and 2002, respectively, were 36.9% and 35.4% for differences between bilateral lung sounds, 52.5% and 55.8% for coarse crackles, 34.1% and 58.3%(p<0.05) for fine crackles, 69.2% and 70.8% for wheezes, 62.1% and 90.7%(p<0.01) for rhonchi, and 22.2% and 32.6% for stridor. In conclusion, 1 month's self-study with “Mr. Lung” to prepare for the objective structured clinical examinations improves auscultation skills.

Objective: We investigated subjective effects of a lactoferrin (LF) -containing supplement on cold-like symptoms and gastroenteritis symptoms.
Method: Healthy women were divided into a LF-consumption group and a non-consumption group. The former intaked LF-containing tablets for 90 days. Subjects filled out questionnaires about cold-like symptoms, gastroenteritis symptoms, and drug use.
Results: Significant decreases were found in the onset of cold-like symptoms and gastroenteritis symptoms in the LF-consumption group compared with non-consumption group.
Conclusion: These results suggest the possibility that LF intake inhibits the onset of common cold and gastroenteritis.

　The WHO reported the importance of IPE (Interprofessional Education) in order to implement team-based medicine smoothly. Some Japanese medical educational institutes presented their IPE programs, which involved real patients, but most IPE programs used scenario-based or standardized patients. Moreover, few reports showed IPE programs for diabetic patient education. We created a new program, called the "Diabetes education class IPE" . Participants were 2 medical, 4 nursing, 4 pharmacy, and 3 dietician students. The students experienced the planning and management of and reflection on diabetes education classes. As a result of reflection, the "Diabetes education class IPE" was viewed as a useful IPE program.

Objective: In our country, the measure for the spread of the generic has been introduced over several-time as part of the moderation in health care cost plan.  However, not having related to an enough spread unlike Europe and America yet is a current state.  Then, we investigated from the view point of patients.  A detailed examination was performed for the acknowledgment level and attitude toward the generic drug.
Design and Method: The questionnaire survey was performed for the patient who used the community pharmacy for dispensing prescription.  The investigation was performed for two weeks (June and July, 2008) at the 50 drugstores in Hokkaido.  The patient attribute, source of information, and kind of the taking medicine were examined as a factor to affect decision making for generic drug substitution.
Result: The main results are as follows.  The patients who did not know generic drugs accounted 52% of the total and the patients who did not know the words called generic drugs was 16%.  This result shows that the degree of the recognition about generic drugs at that time was still low.  The information source for the patients who learned generic drugs were articles of the newspaper, a TV program, and advertising with accounted 52% of the total.  Also, the patients who prefer generic drugs in the future were 64%.  In the relationships between presence of wish for generic drugs and the source of information, the case of from the doctor, was significant (p<0.05) and the case from the pharmacist showed the tendencies of statistical significance (p=0.076).
Conclusion: From the viewpoint of medicine costs restraint in our country, it seems that the pharmacist contributes for the patient’s generic drugs selection expected positively.

BACKGROUND: Pretesting is the key to understanding how the intended audience will react to the message. Resistant reactions affect message processing or can lead to undesirable boomerang effects. The objective of this study was to develop a rating scale for measuring active (reactance) and passive (disengagement) resistance to persuasive health messages. METHODS: Six candidate items (3 items for disengagement and 3 items for reactance) were generated based on literature review. A web-based survey was conducted among Japanese adults aged 25-64 years to verify the reliability and validity of the 6-item resistance scale. Participants were asked to rate one of the advance care planning (ACP) promotion messages. All scale items were scored on a 1-to-5 point Likert scale and they were averaged to produce the resistance score. RESULTS: Explanatory factor analysis revealed a two-factor solution that agreed with the disengagement and reactance domains, respectively. Correlation coefficients between each set of items ranged between 0.30-0.69. Cronbach alpha (0.86) indicated satisfactory internal consistency of the set of items. Confirmatory factor analysis showed a good fit of the two-factor model with CFI = 0.998, SRMR = 0.011, and RMSEA = 0.041. The resistance score showed a moderate positive correlation with negative emotional responses (displeasure γ = 0.55, anger γ = 0.53) and was significantly inversely related to the persuasiveness score (γ = -0.50). Multivariable logistic regression analysis showed that the odds ratio for ACP intention per 1-point increase in the resistance score was 0.47 (95% confidence interval 0.40-0.56) with adjustment for the persuasiveness score. CONCLUSION: The 6-item resistance scale exhibited adequate reliability and validity for measuring audience resistance when applied to the ACP promotion messages in Japanese people. The scale will be useful for pretesting health messages to make them more acceptable to the intended audience. TRIAL REGISTRATION Not applicable; this is not a report of intervention trial.

Dynamic knee valgus is considered a risk factor for anterior cruciate ligament (ACL) injuries. This study identified how knee in distance (KID) and hip out distance (HOD) affect one’s lateral trunk lean (LTL). The results were also tested for reliability. Fifteen female basketball players (30 legs) from a university participated in this study. The participants performed single-leg squats by bending the knee of the supporting leg to 60°. The trials were recorded using a video camera. The KID, HOD, and LTL were measured with two-dimensional images using the Dartfish software, which measured the maximal knee valgus. The Pearson’s correlation coefficient was used to measure the correlation between dynamic knee valgus (KID and HOD) and LTL. Additionally, the Interclass Correlation Coefficient (ICC) was used to measure the reliability of the KID, HOD, and LTL data sets. The statistical significance was established at a level of p<0.05. Results showed that the KID and LTL had a significantly negative correlation, measured at r=-0.227, p<0.05. The ICC (2.1) values were: 0.83 for HOD, 0.99 for KID, and 0.96 for LTL; while the ICC (1.2) values were: 0.86 for HOD, 0.83 for KID, and 0.85 for LTL. The two-dimensional analysis technique revealed that the values were highly reliable. In sum, dynamic knee valgus had a negative correlation with LTL during single-leg squats. Therefore, it was suggested that the factors of dynamic knee valgus might be evaluated using LTL on two-dimensional screening test.

It has been reported that physical fitness of breast cancer patients is relatively lower due to the cancer treatment such as surgery, chemotherapy, or endocrine therapy. Previous studies have revealed that not only cardiorespiratory fitness but also muscle strength is lower among breast cancer patients than no disease women and these symptoms may aggravate the health-related quality of life. However, there is no study which has focused the physical fitness level in Japanese breast cancer survivors. The purpose of this study was to investigate the physical fitness level and the relationship between exercise habituation and physical fitness level in Japanese breast cancer survivors. Fifty breast cancer survivors participated in this study. Participants were assigned to either exercise habituation group (n=25) or non-exercise group (n=25). We evaluated exercise habituation using an original questionnaire and examined various physical fitness level. Body weight, body mass index, and percent body fat were significantly lower in the exercise habituation group than non-exercise group. T-score of cardiorespiratory fitness was significantly higher in the exercise habituation group than average Japanese women. These results suggested that exercise habituation is relative to body weight and cardiorespiratory fitness level in Japanese breast cancer survivors.
