Verification of the Effectiveness of the Health Support Pharmacy “Toyonaka Model,” an Industry-Government-Academia Collaboration Project Aiming to Promote Community Health through the Information from Community Pharmacies via Digital Signages / 社会薬学

Advances in information and communication technology (ICT)-especially, the spread of social networking services (SNSs)-have facilitated the dissemination of information and an explosion of health information lacking scientific evidence. Therefore, we believe that community pharmacies are the most suitable bases for distributing health information. In 2019, we launched the health support pharmacy “Toyonaka Model” in collaboration with the pharmaceutical association, municipal government, and university. Touch-panel digital signage (DS) was used for real-time distribution of ever-changing information and a rapid grasp of pharmacy users’ responses to various types of information. Between September 2019 and August 2021, one DS was installed in a pharmacy in each of Toyonaka City’s seven areas along with 14 questions on the usefulness of the delivered information. Respondents answered the 14 questions by a tablet or questionnaire; touch logs for DS were collected. When a pharmacy user consulted with a pharmacist about information delivered via DS, the contents were recorded and described by the pharmacist on a 4-point scale (e.g., “inquiry only,” “went through to execution”). From the 850 completed questionnaires and 61,565 touches, 88.7% of the respondents indicated that the information was useful, and 90.0% expressed interest in receiving more health information in the future. Thus, health information provided by DS may be useful to pharmacy users, as demonstrated by 113 cases in which the pharmacist was consulted regarding such information. In 62 of these cases, there were indications that the DS information might have influenced users’ behavior and intended actions.

Questionnaire Survey on the Pharmacy Students’ Attitudes and Opinions following the Dementia Supporter Education Lecture / 社会薬学

Although pharmacy students receive professional education regarding dementia, it is the current state that many pharmacy students cannot learn the countermeasures to treat people with dementia. We conducted the “Otani dementia supporter education lecture” which improved a lecture by Caravan Mate targeting pharmacy students, and subjected the students to a questionnaire survey after the lecture. One hundred and forty-nine students participated and there were most percentages of third grades by 40.9%. After attending the lecture, most of the students opined that one can help a patient with dementia by understanding the patients’ feeling. It was the answer obtained by the lecture for the students to ensure that a pharmacist responds to consultations and requests from their family with a dementia patient. The first information that the students additionally wanted to know about dementia pertained to a method for the early detection of dementia. The results of text mining on the correspondence for patient with dementia showed that categories of “dementia patient,” “correspondence,” “understanding the patients’ feeling,” and “tact,” independently had strong mutual relations. Moreover, the results of text mining on the feedbacks obtained for the lecture showed that categories such as “dementia patient,” “When close person and one were,” “A chance was obtained,” and “correspondence” independently had significant mutual relations. Students who participate in this lecture understand that it is necessary to contact with dementia patients appropriately and feel that there is a need to become a presence that can support dementia patients as a pharmacist in the future. Therefore, this lecture was effective in motivation to correspondence to a person with dementia.

Noninvasive Assessment of Advanced Fibrosis Based on Hepatic Volume in Patients with Nonalcoholic Fatty Liver Disease

BACKGROUND/AIMS: Noninvasive liver fibrosis evaluation was performed in patients with nonalcoholic fatty liver disease (NAFLD). We used a quantitative method based on the hepatic volume acquired from gadoxetate disodium-enhanced (Gd-EOB-DTPA-enhanced) magnetic resonance imaging (MRI) for diagnosing advanced fibrosis in patients with NAFLD. METHODS: A total of 130 patients who were diagnosed with NAFLD and underwent Gd-EOB-DTPA-enhanced MRI were retrospectively included. Histological data were available for 118 patients. Hepatic volumetric parameters, including the left hepatic lobe to right hepatic lobe volume ratio (L/R ratio), were measured. The usefulness of the L/R ratio for diagnosing fibrosis ≥F3–4 and F4 was assessed using the area under the receiver operating characteristic (AUROC) curve. Multiple regression analysis was performed to identify variables (age, body mass index, serum fibrosis markers, and histological features) that were associated with the L/R ratio. RESULTS: The L/R ratio demonstrated good performance in differentiating advanced fibrosis (AUROC, 0.80; 95% confidence interval, 0.72 to 0.88) from cirrhosis (AUROC, 0.87; 95% confidence interval, 0.75 to 0.99). Multiple regression analysis showed that only fibrosis was significantly associated with the L/R ratio (coefficient, 0.121; p<0.0001). CONCLUSIONS: The L/R ratio, which is not influenced by pathological parameters other than fibrosis, is useful for diagnosing cirrhosis in patients with NAFLD.

Relationships between Genetic Variations of PNPLA3, TM6SF2 and Histological Features of Nonalcoholic Fatty Liver Disease in Japan

BACKGROUND/AIMS: It is important to determine the noninvasive parameters of histological features in nonalcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the value of genetic variations as surrogate markers of histological features. METHODS: The parameters that affected the histological features of NAFLD were investigated in 211 Japanese patients with biopsy-proven NAFLD. The relationships between genetic variations in PNPLA3 rs738409 or TM6SF2 rs58542926 and histological features were analyzed. Furthermore, the impact of genetic variations that affected the pathological criteria for the diagnosis of nonalcoholic steatohepatitis (NASH) (Matteoni classification and NAFLD activity score) was evaluated. RESULTS: The fibrosis stage of PNPLA3 GG was significantly more progressive than that of CG by multiple comparisons. Multivariate analysis identified PNPLA3 genotypes as predictors of fibrosis of stage 2 or more, but the impact tended to decrease at stage 3 or greater. There were no significant differences among the histological features of the three genotypes of TM6SF2. PNPLA3 genotypes partly affected the definition of NASH by the NAFLD activity score, but TM6SF2 genotypes did not affect the definition of NASH. CONCLUSIONS: In Japanese patients with biopsy-proven NAFLD, PNPLA3 genotypes may partly affect histological features, including stage of fibrosis, but the TM6SF2 genotype does not affect histological features.

Questionnaire Survey after a Lecture for Residents on Usage of Generic Drugs / 社会薬学

<p>The awareness of many residents on generic drugs has increased recently, which is also reflected in their increased consumption. Enlightenment activities for citizens have become an important tool to further promote the use of generic drugs. We performed a questionnaire survey and assessed residents’ consciousness after a lecture on generic drug usage in a people’s forum. We received responses from 105 of the recruited 127 participants. Most questionnaire respondents were from the age group of 70 years and comprised about half of the sample. The respondents having undefined will to the question about use of generic drugs was the most frequent. Only a few participants answered that they hoped getting generic drugs from a pharmacy or hospital. The concerns and future requests for generic drugs were the cost of medicine, validity, safety, and quality. The middle group by which the participants were classified into a positive group, a middle group and a negative group among question on usage and request of generic drugs, in its percentage each age groups, was most. Many respondents answered that generic drug use “should be spread” after the lecture. However, it was identified that the communication between doctor, pharmacist, and the patient on generic drug use is insufficient in the open question. Enlightenment activities for citizens will become necessary because half of the respondents expressed negative opinions on the use of generic drugs.</p>

What Is the Most Effective Drug Delivery System for Cisplatin during the Treatment of Hepatic Tumors with Single-Session Transcatheter Chemotherapy? A Pilot Study

BACKGROUND/AIMS: The aim of this study was to determine the pharmacodynamics of cisplatin following three different treatment procedures for intrahepatic arterial infusion therapy for hepatocellular carcinoma (HCC). METHODS: We divided 13 HCC patients into the following three groups: group A, lone injection of cisplatin (n=3); group B, combined injection of cisplatin and lipiodol, with embolization using small gelatin cubes (GCs) (n=5); and group C, injection of suspended lipiodol with cisplatin powder, with embolization using small GCs (n=5). In each group, the free cisplatin concentration in the hepatic vein was measured at 0, 5, 10, and 30 minutes. RESULTS: The mean free cisplatin concentrations were as follows. For group A, the mean was 48.58 microg/mL at 0 minute, 7.31 microg/mL at 5 minutes, 5.70 microg/mL at 10 minutes, and 7.15 microg/mL at 30 minutes. For the same time points, for group B, the concentrations were 8.66, 4.23, 3.22, and 1.65 microg/mL, respectively, and for group C, the concentrations were 4.81, 2.61, 2.52, and 1.75 microg/mL, respectively. The mean area under the curve (AUC)0-infinity for the free cisplatin concentration was 7.80 in group A, 2.48 in group B, and 2.27 in group C. The AUC0-infinity for the free cisplatin concentration gradually decreased, from group A to group C. CONCLUSIONS: These results indicate that the combination of lipiodol and small GCs may be useful for delaying cisplatin drainage from the liver.

Transcatheter Arterial Chemotherapy with Miriplatin for Hepatocellular Carcinoma Patients with Chronic Renal Failure: Report of Three Cases

Miriplatin is a novel lipophilic platinum complex that was developed to treat hepatocellular carcinoma (HCC). Although HCC patients frequently have coexisting chronic renal failure, little prospective data are available regarding the clinical toxicity of chemotherapeutic agents used to treat HCC patients with chronic renal failure. In a phase II study, the plasma concentration of total platinum in patients who received miriplatin was very low, and no severe renal toxicity caused by miriplatin injection was reported. Here, we present three cases of HCC with stage 4 chronic renal failure who received transcatheter arterial chemotherapy with miriplatin. All cases were male, ages 72, 84, and 83 years, and had serum creatinine levels of 2.3, 1.6, and 1.9 mg/dL, respectively. Their estimated glomerular filtration rates were 21.9, 20.3, and 22.2 mL/min, respectively. All cases were treated for unresectable HCC with transcatheter arterial chemotherapy with miriplatin. No serious adverse events were observed, and serum creatinine levels did not elevate, even in the patient who experienced renal failure caused by cisplatin administration. These results might suggest that transcatheter arterial chemotherapy with miriplatin can be safely used in HCC patients with chronic renal failure.
