The protection to the cytotoxicity of 24S-hydroxycholesterol on the brain-derived cells should be useful as a new therapy of Alzheimer’s disease. In this study, we have revealed neuroprotective effect of polyphenol, especially (−)-epigallocatechin-3-gallate and (−)-epicatechin gallate on cytotoxicity of 24S-hydroxycholesterol. These results suggest the possibility of a new complementary therapy for Alzheimer’s disease.

Objective: Difficulty in extracting tablets from a press through pack (PTP) is believed to reduce prescription drug compliance.　This is a particularly serious issue for the elderly or for those who have physical disabilities affecting the fingers.　In this study, the squeezing force necessary to extract tablets from PTPs was measured for 33 commercial tablet products using a force gauge (FG).　Additionally, a sensory test was conducted to determine the degree of difficulty in extracting tablets from PTPs by squeezing, and the correlation between the difficulty measure and squeezing force was evaluated.Methods: The squeezing force for 33 products was measured by FG.　The sensory test was conducted with 64 subjects.　Four products, each with a different squeezing force, were used for the sensory test.　In the test, each subject ranked the products in order according to the amount of force required to extract the tablets.　Each product's total score was used in the statistical analysis.Results: The average squeezing force of the 33 products was 33.1 ± 6.9 〔N〕, and significant differences were observed among the products.　The sensory test revealed that each subject could significantly distinguish the amount of force required to extract the tablets from each product.Conclusion: A positive correlation was observed between the squeezing force obtained using FG and the results from the sensory test.　This suggests that squeezing force can be used as an indicator for the usability of the product.　Therefore, the degree of difficulty in extracting tablets from PTPs should be considered when selecting drugs for the elderly.

Background/Aims: Bleeding is a complication of endoscopic snare papillectomy for ampullary tumors. This study aimed to investigate the clinical efficacy of hypertonic saline-epinephrine (HSE) local injection before endoscopic papillectomy for prevention of bleeding. Methods: We retrospectively reviewed the data of 107 consecutive patients with ampullary tumors who underwent endoscopic papillectomy. The rates of en bloc resection, pathological resection margins, and prevention of immediate or delayed bleeding in the simple snaring resection group (Group A) and the HSE injection group (Group B) were compared. Results: A total of 44 and 63 patients were enrolled in Groups A and B, respectively. The total complete resection rate was 89.7% (96/107); the clinical complete resection rates in Group A and Group B were 86.3% (38/44) and 92.1% (58/63), respectively (p=0.354). Post-papillectomy bleeding occurred in 22 patients. In Groups A and B, the immediate bleeding rates were 20.5% (9/44) and 4.8% (3/63), respectively (p=0.0255), while the delayed bleeding rates were 7% (3/44) and 11% (7/63), respectively (p=0.52). The rates of positive horizontal and vertical pathological margin in both groups were 27% and 16%, respectively. Conclusions HSE local injection was effective in preventing immediate bleeding and was useful for safely performing endoscopic papillectomy for ampullary tumors.

Objective: Chemotherapy-induced nausea and vomiting (CINV) can affect a patient’s quality of life and make them resistant to the treatment. We created an electronic patient reported outcome ePRO-linked pharmaceutical management system (PMS) for CINV (CINVePRO) for storing information, such as nausea and vomiting status, food intake, etc., and suggesting the type of anti-nausea medication and dosage changes to the physicians for controlling CINV.Design: At the Gifu University Hospital, the collaborative research institute, inpatients and pharmacists in charge used CINVePRO-PMS, and a questionnaire survey was done to assess the system’s reliability.Methods: The daily entry of data into CINVePRO shows the number and duration of vomiting, degree of nausea, and amount of food consumed and displays a list and graph of these data over time. The PMS enables pharmacists to list the presence or absence of nausea and the number of vomiting for all patients in their charge and record the intervention and display its list.Results: The questionnaire was distributed to 17 inpatients. All patients and pharmacists answered the questionnaire. According to the results of the questionnaire survey of patients, each screen of CINVePRO received a good evaluation that mentioned it was “easy to understand,” “easy to use,” and “especially useful for communicating one’s symptoms.” In addition, the results of a questionnaire survey of the pharmacists revealed that the system was rated as easy to check the patients’ symptoms and practical to use.Conclusion: CINVePRO-PMS was evaluated as a convenient and applicative system. However, linking CINVePRO to the electronic medical record of each hospital is necessary for sharing it among multiple professions.
