Objective: We investigated the health-related quality of life (HRQoL) of patients with chronic diseases in community pharmacies in Japan and examined its relationship to patient attributes, an area that has not been previously studied.Method: We surveyed 1,500 participants with chronic diseases and 1,500 from the general population without chronic diseases (Free-GP) using the EuroQol (5-dimension, 5-level) questionnaire. Patient attributes included the number of drugs used, duration of medication, number of chronic conditions, perceived disease severity, and perceived treatment importance. Logistic regression analyses assessed how these attributes influenced the likelihood of reporting “full health” (no problems on all HRQoL questions) among patients with chronic disease. An exploratory decision tree analysis was performed to identify patient attributes that might decrease HRQoL.Result: The HRQoL score of patients (0.856) was lower than that of Free-GP (0.942). The HRQoL of patients tended to increase with aging. Among patients, the mean HRQoL score was 0.781 for polypharmacy, which decreased with the addition of disease severity perception (even lower for those in their 20s-40). Even in the absence of polypharmacy, the average HRQoL score decreased when patients were in their 20s with multimorbidity. The HRQoL scores of non-polypharmacy patients in their 30s or older were higher than the mean scores of patients with chronic disease.Conclusion: To provide extensive care for patients with reduced HRQoL in community pharmacies, it is necessary to focus on polypharmacy. Reduced HRQoL should be considered in younger patients with multimorbidity, even in the absence of polypharmacy.

The COVID-19 pandemic has substantially transformed the healthcare sector. While telemedicine has rapidly advanced, the essential roles of medical professionals, such as doctors and nurses, have been reaffirmed. Even prior to the pandemic, we had been evaluating pharmacists’ interpersonal roles from both patient and pharmacist perspectives using role theory. Accordingly, we investigated whether perceptions of pharmacists’ roles changed among patients and pharmacists through comparable surveys conducted before and during the pandemic. A nationwide online survey was conducted twice (April 30-May 7, 2021, and April 22-25, 2022), targeting 1,000 patients who used community pharmacies and 600-800 pharmacists employed at those pharmacies across Japan. The questionnaire comprised 12 items: 11 concerning pharmacists’ interpersonal roles, including communication, comprehending medication effects, and serving as a family pharmacist or drug expert, and one additional item addressing expectations during the pandemic. A five-point Likert scale was used. Compared with pre-pandemic results, patient evaluations revealed no statistically significant changes in either 2021 or 2022. However, pharmacists’ self-evaluations declined in response to the question, “Are pharmacists more expert in medicine than doctors?” The newly introduced question regarding pharmacists’ contributions to the community received higher ratings from patients than from pharmacists, indicating considerable patient expectations. Overall, only pharmacists’ perceptions changed, demonstrating decreased confidence and self-evaluation. Conversely, patient perceptions remained stable, suggesting that pharmacists are more sensitive to social changes than patients themselves.

Hands-on training is a crucial part of education in neuroendovascular treatment to ensure safe and rapid acquisition of techniques. However, there is a significant gap between training and actual clinical practice. This study will introduce innovations for more practical thrombus retrieval training that was developed in this process. A Smart Vascular Model 3 in 1 was used. A pink pseudothrombus was inserted into the M1 (horizontal segment of the middle cerebral artery) section of the model. Then, a “red underlay” purchased at a stationery store was placed to cover the proximal part of M1 and beyond so that the pseudothrombus was not visible. The thrombus was retrieved during training by looking for the location of the thrombus based on the behavior and resistance of the tip of the guidewire and deployment of the stent retriever. The participants were required to have detailed observation skills and precise manipulation skills using a red film to prevent the direct visualization of the pseudothrombus. The implementation of this innovation to the previous hands-on training made the training more practical and effective. If the exact thrombus location can be determined by the behavior of the wire tip, the device’s capabilities can be maximized, and rapid retrieval can be expected. It could also reduce complications, as unnecessary peripheral guidance of the device could be avoided.

Transarterial embolization using Onyx is a well-established treatment for dural arteriovenous fistulas (DAVFs). However, complications can arise when Onyx migrates into the venous side, impairing the draining veins. We encountered a case where Onyx, injected through the arterial side, strayed into the jugular vein, forming a hairball-like structure. Our study aimed to investigate the underlying mechanism of this unusual phenomenon. We postulated that Onyx precipitates into thread-like shapes when passing through extremely narrow openings. To test this, we extruded Onyx from a syringe through a 27-gauge needle into a silicone tube with flowing water. By varying the flow speed, we observed the hardening behavior of Onyx. Under slow flow, the extruded Onyx quickly solidified at the needle tip, forming a round mass. Conversely, high-speed flow resulted in Onyx being dispersed as small pieces. We successfully replicated the formation of “Onyx threads” under continuous slow flow conditions, similar to our case. This phenomenon occurs when Onyx unexpectedly migrates to the draining vein through a tiny opening during transarterial embolization for arteriovenous shunt diseases. Early recognition and appropriate measures are necessary to prevent occlusive complications in the draining veins and the pulmonary system.

Purpose:
We investigated the age distribution of cerebral saccular aneurysms in various locations to clarify the differences by location and discuss the mechanism of formation.
Materials and Methods:
We retrospectively assessed clinical material obtained from 1,252 unruptured aneurysms treated with endovascular embolization between 2004 and 2019. Age, sex, laterality, and size were investigated by the location of aneurysms, classified as cavernous internal carotid artery (ICA), paraclinoid ICA, supraclinoid ICA, anterior communicating artery, anterior cerebral artery, middle cerebral artery, basilar artery complex, and posterior inferior cerebellar artery. Paraclinoid aneurysms were subclassified into 3 patterns according to their projecting direction: S-type, with superior protrusion; M-type, with medial protrusion; and P-type, with posteroinferior protrusion.
Results:
There was no significant difference by location for sex, laterality, and size. The mean age of patients with paraclinoid aneurysms (56.5 years old) was significantly lower than that of other aneurysm patients (64.3 years old). Notably, 40% of the patients with M-type aneurysms were <50 years old. This percentage was significantly higher than that of aneurysms at other locations (P<0.05).
Conclusion
We found a young female predominance for patients with paraclinoid carotid aneurysms. This study may suggest that congenital factors contribute to paraclinoid aneurysm formation as well acquired factors, such as hemodynamic stress, atherosclerotic wall damage, and local inflammation.

Drug dispensing is a statutory and designated duty of a pharmacist. We aimed to examine the changes in the nature of drug dispensing using a text mining method. Our corpus consisted of text documents from “Chozai Shishin”, the most standard manual for dispensing drugs in Japan, Editions 1 to 13 (Japan Pharmaceutical Association), and we used the KH Coder software for text mining. We constructed networks showing the association between frequent word co-occurrence and edition number, and co-occurrence relations for frequent words in each edition. We found that “patient” superseded “dispensing” as a frequent term over time. “Dispensing” was another frequent term with a highly centralized node in each edition. Accordingly, we targeted the term “dispensing” for network analysis to depict its co-occurrence relations. We found that the range of related words for “dispensing” broadened from “preparation” and “compounding” to include “patient adherence instructions”, “assessment”, “medical treatment”, and “information provision”. Accordingly, we concluded that the content of “dispensing”, which is a pharmacist’s duty, has expanded from the duties of “dispensing drugs” to include “responding to patients” within the definition of “dispensing”, and we were able to present this finding as objective data by using the mechanical method known as text mining.

Objective: In this study, we evaluated distinctive types of physical predisposition in patients with common side effects.
Method: We selected 500 and 1,200 individuals with and without a previous diagnosis of side effects, respectively, through web-based research. Then, we conducted a decision tree analysis for investigating the status of 100 types of physical predisposition in these individuals.
Results and Conclusion: The individuals who had suffered from hepatic disorder and answered “relevant” for “predisposition to swelling” (likelihood ratio of a positive result [LR+] 2.17; p=0.004) and “very relevant” for “predisposition to skin dryness” (LR+ 3.52; p<0.001) enhanced the probability of extracting individuals who developed side effects. The individuals who had suffered from skin disorder and answered “relevant” for “predisposition to eczema and inflammation” and “not relevant” for “predisposition to higher temperature” had an LR+ of 2.22 (p<0.001). The individuals with “predisposition to worsening of physical condition on a rainy or high-humidity day” are more likely to develop side effects with the use of antibiotics and NSAIDs, compared to those without this predisposition (antibiotics: LR+ 2.33; NSAIDs: LR+ 2.51). The results of this study indicate that we can identify patients with a high risk of side effects through an interview on predisposition.
