To combat the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), novel vaccine modalities, such as messenger RNA vaccines, were rapidly developed and have shown high efficacy. This new vaccine technology, underpinned by intensive immunological analysis, is now being applied to the production of other vaccines. For over 10 years, we have been developing therapeutic vaccines for non-infectious diseases. The epitope vaccine approach, which combines a B-cell epitope with exogenous T-cell epitopes presented through major histocompatibility complex molecules, has been proposed to induce antibody production. This vaccine type is designed to efficiently induce a blocking antibody response against the self-antigen without activating cytotoxic T cells. If therapeutic vaccines become established as treatment options for conditions such as hypertension or dyslipidemia, their administration—potentially only a few times per year—could replace the need for daily medication. Nucleic acid drugs, including small interfering RNA and antisense oligonucleotides, have recently received attention as long-term agonists, similar to vaccines.Therefore, therapeutic vaccines or nucleic acid drugs could represent a novel strategy for controlling the progression of cardiovascular diseases. It is hoped that the accumulation of immunological findings and advances in vaccine technology will provide valuable insights into the development of vaccines for treating cardiovascular diseases.

BACKGROUND:
Sedentary behaviors have recently become an important public health issue. We aimed to investigate the relationship between screen time and nutrient intake in children and adolescents.
METHODS:
The present study was conducted in 2013. Data were collected from children and adolescents aged between 6 and 15 years old in Shika town. Questionnaires were distributed to 1459 subjects, 1414 of whom participated in the study (96.9%). Sedentary behaviors were assessed based on participants' screen behaviors (television (TV) viewing, personal computer (PC) use, and mobile phone (MP) use). The main outcomes were the intake of nutrients from a validated food frequency questionnaire. Analysis of covariance (ANCOVA) was used to examine the significance of differences in nutrient intake estimates. Multivariate linear regression analyses, adjusting for age, BMI, and physical activity, were used to provide parameter estimates (β) and 95% CI for the relationship between screen time and nutrient intake.
RESULTS:
In boys, longer TV viewing times correlated or tended to correlate with a lower intake of protein, potassium, calcium, iron, vitamin K, vitamin B-2, and total dietary fiber. In girls, longer TV viewing times correlated with a lower intake of protein, sodium, calcium, vitamin D, and vitamin B-2. Longer TV viewing times correlated with a higher intake of n-6 fatty acids in girls. PC use was related or tended to be related to a lower intake of potassium, iron, vitamin K, and folic acid in boys, but not in girls. A relationship was observed between MP use and a lower intake of vitamin K in boys, and MP use and a higher intake of vitamin D in girls.
CONCLUSIONS
The present results revealed that longer TV viewing times are associated with less protein, minerals, vitamins, and total dietary fiber intake in children and adolescents. It was also revealed that boys with PC use have less minerals and vitamins. These results support the need to design intervention programs that focus on decreasing TV viewing time in both sexes and PC use in boys while encouraging adherence to dietary guidelines among children and adolescents.

The patient was a 57-year-old man who, in 1973, at 19 years of age, had undergone mitral valve replacement for mitral valve stenosis using a Björk-Shiley Delrin (BSD) valve. When the patient visited our hospital, he was living in an assisted-living facility due to paresis of the right side of the body, dysarthria, and other sequelae of cerebral infarction. The patient was referred to and visited our hospital with a chief complaint of chest pain in 2011, 38 years after the BSD valve was implanted. In 2012, mitral valve re-replacement, aortic valve replacement, and tricuspid annuloplasty were performed for congestive heart failure associated with prosthetic valve failure, combined aortic stenosis and insufficiency, and tricuspid insufficiency, which were identified by transesophageal echocardiography. The patient's postoperative course was generally favorable. The disc of the resected prosthetic valve showed a groove and bidirectional cracks caused by wear, and its condition suggested a risk of potential rupture. Transthoracic echocardiography on admission showed mild to moderate prosthetic transvalvular regurgitation, and the symptoms were therefore unlikely to have resulted from the prosthetic valve failure alone at this time. Consequently, it was considered that the heart failure was attributed to the prosthetic transvalvular regurgitation caused by the disc abnormalities in addition to the combined valvular disease by transesophageal echocardiography. In this case, detailed investigation of the heart failure by transesophageal echocardiography led to the discovery of prosthetic valve abnormalities, thus enabling the prevention of a serious cardiac accident due to disc rupture. Detailed examination by transesophageal echocardiography is essential, and early surgical intervention should also be considered if transthoracic echocardiography suggests even a minor prosthetic valve abnormality in a patient who has had this prosthetic valve implanted for such a long time.

Objective: Elderly patients commonly experience adverse drug events (ADEs) owing to their poor drug metabolizing and excretion ability, and these often cause multiple organ dysfunction syndrome. Therefore, it is important that we identify the adverse drug events early on during prognosis. We searched for oral medicines that might exacerbate the prognosis of ADEs in elderly patients.
Methods: The objects under analysis were oral medicines that were registered in the Japanese Adverse Drug Event Report database (JADER). The associations between the elderly/non-elderly patients and exacerbation risk/non-exacerbation risk were analyzed by risk ratios (RR). The signal detection of exacerbation risk was defined as 95% confidence interval of lower limit of risk ratio>1 and χ2≥4.
Results: The oral medicines that might markedly exacerbate the prognosis of ADEs in the elderly patients in comparison with the ADEs of young patients included 84 items, of which 63 have not been described as potentially inappropriate medicines in all guidelines for medical treatment of the elderly patients.
Conclusion: In this study, while we could not search for oral medicines having a high risk of ADEs, we were able to search for oral medicines that might exacerbate the prognosis of ADEs in elderly patients. This result could contribute to the proper use of medicines in the elderly patients.

Objective: Prescription check and inquiry is one of the most important operations of pharmacists to provide optimal drug therapy to the patient. Although a number of studies related to inquiries of prescriptions have already been reported, there is little report about requests for doctor and hospital based on the examples. Therefore, this study aimed to clarify the current problems revealed by inquiries about prescriptions by not only analyzing these inquiries but also investigating requests for doctors and hospitals.
Methods: We investigated 6,255 inquiries about prescriptions and requests for doctors and hospitals at 584 insurance pharmacies from August 4 to 10, 2014. Then, the inquiries about prescriptions and requests for doctors and hospitals were categorized.
Results: The most frequent category of inquiries about prescriptions was “Questions about administration and dosage” (21.5%). On the contrary, the most frequent request for doctors was “Efficiency in gathering information from and providing information to a patient” (2,067 cases).
Conclusions: The present study clarified current problems revealed by inquiries about prescriptions by investigating requests for doctors and hospitals that were based on examples. Furthermore, the problems were classified into ten categories, and these should be noted by doctors and hospitals at the time the prescription was issued.

Objective: Many of the elderly patients are suffering from constipation, are using the oral laxative. However the risk assessment of the oral laxative is not performed. Therefore, we used Japanese Adverse Drug Event Report database (JADER) and examined for the safety of the oral laxative in the elderly patients.
Methods: Since the analysis target medicines; 12 oral laxatives and target ADEs; “digestive disorders” and “electrolyte abnormality,” the JADER database for April 2004 to January 2015 were analyzed in adults of age exceeds 60. We used the reporting odds ratio for a safety index of drugs, using reporting odds ratio, when the Lower bound of the 95% two-sided confidence interval exceeds 1, it is the signal detection of ADE.
Results: The oral laxatives detected the signal of “digestive disorders” were three medicines, and “electrolyte abnormality” were five medicines. Especially, for electrolyte abnormalities not only increases the blood magnesium values as magnesium oxide, that there is also affect other electrolyte revealed.
Conclusion: Some oral laxatives were also intended to signal detections of the adverse events that are not listed in the attached document, it is necessary to pay attention to the use of them for the elderly patients.

The Medication Guides for Patients (MGPs) are being offered as information on prescription drugs for patients by the Ministry of Health, Labour and Welfare (MHLW). The MHLW published the Risk Management Plan in April, 2012, and it noted that the MGPs should be utilized in usual risk minimization activities. It is not clear, however, whether the MGPs are efficiently utilized in actual settings. Hence, we conducted a questionnaire survey of the pharmacists in the pharmacies with dispensing and the hospitals in Mie and Yamagata prefectures to investigate the actual circumstances of MGPs utilization and to understand the existing barriers associated with the use of the MGPs as medication instructions for patients. We sent the questionnaires by mail and obtained responses from 444 facilities (33.9%) of 1,309 facilities. The recognition level of the MGPs was about 30 percent in the dispensing pharmacies, and about 50 percent in the hospitals. The MGPs were utilized as a common communication tool with the patients in approximately 20 percent of the facilities. Many respondents requested that the frequency of important and other adverse reactions should be described in the MGPs, and wider ranges of MGPs should be further implemented.
Moreover, our data suggests the problem is that the present MGPs are mainly applied to special types of patients, such as those with higher literacy level or those who requested a detailed explanation. Thus, it is apparent that it is necessary to review the MGPs contents again to improve their practical benefits and disseminate them more widely.

A 28-year-old man was involved in a traffic accident that sandwiched his chest between a wall and a truck. Shortness of breath and other symptoms started to appear several years later. Echocardiography at that time showed severe tricuspid regurgitation due to a failed valve and ruptured chordae in the anterior leaflet. He was followed up with medication. Leg edema developed at the age of 62 years and worsening symptoms of heart failure over a period of 6 months indicated a need for surgery. Intraoperative findings revealed the ruptured chordae attached to the anterior leaflet and a scarred myocardium at the septomarginal trabeculation. The tricuspid valve was surgically repaired, the anterior leaflet chordae were surgically reconstructed, an annuloplasty ring was implanted to address the tricuspid regurgitation and atrial fibrillation was treated using the Maze procedure. Surgery 34 years after trauma has improved hemodynamic cardiac function and normalized the cardiac rhythm in this patient.

BACKGROUND/AIMS: To confirm the feasibility of using newly developed endoscopic ultrasound (EUS) with Zone sonography(TM) technology (ZST; Fujifilm Corp.). METHODS: Seventy-five patients with pancreatic disorders were enrolled: 45 with intraductal papillary mucinous neoplasm; 15 with ductal carcinoma; five with neuroendocrine tumors; three with serous cystic neoplasms; and seven with simple cysts. The endoscopes used were EG-530UR2 and EG-530UT2 (Fujifilm Corp.). Two items were evaluated: visualization depth among four frequencies and image quality after automatic adjustment of sound speed (AASS), assessed using a 5-scale Likert scale by two endosonographers blinded to disease status. Because sound speed could be manually controlled, besides AASS, image quality at sound speeds of 1,440 and 1,600 m/sec were also assessed. RESULTS: In all cases, sufficient images were obtained in the range of 3 cm from the EUS probe. Judgments of image quality before AASS were 3.49+/-0.50, 3.65+/-0.48, respectively. After AASS, A and B scored 4.36+/-0.48 and 4.40+/-0.49 (p<0.0001). There were significant differences in the data before and after AASS and plus 60 m/sec, but no significant difference between the datasets were seen after AASS and at sound speeds manually set for minus 100 m/sec. CONCLUSIONS: EUS with ZST was shown to be feasible in this preliminary experiment. Further evaluation of this novel technology is necessary and awaited.
