Introduction: We aimed to evaluate the impact of lifestyle modifications on the risk of eradication failure in patients undergoing first-line therapy for Helicobacter pylori infection.Methods: A survey was conducted in a community pharmacy to assess changes in alcohol consumption, smoking, and high-fat diet intake before, during, and after first-line therapy for H. pylori infection in enrolled patients.Results: A total of 100 patients (response rate: 3.4%) were included in the analysis. Before therapy, 20 patients (20%) smoked, 35 patients (35%) consumed alcohol, and 91 patients (91%) had a high-fat diet. During therapy, the proportion of patients who changed their habits was 15.0% (3/20) for smoking, 71.4% (25/35) for alcohol consumption, and 28.6% (26/91) for high-fat diet. However, the continuation of these changes post-therapy was minimal.Conclusion: Among patients undergoing first-line therapy for H. pylori infection, lifestyle habits that increase the risk of eradication failure were prevalent, with many patients maintaining their habits during therapy except for alcohol consumption. These findings provide fundamental data for lifestyle counselling during eradication therapy.

Objective: To determine the extent of pharmacists’ burden of inquiries from healthcare professionals in community pharmacies. Design: A descriptive cross-sectional study. Methods: A web-based survey was administered to pharmacists affiliated with Medical System Network Group, Inc.’s community pharmacies in Japan. The survey was conducted from February 15 to March 31, 2022. The primary outcome was the burden of inquiries from healthcare professionals and the secondary outcome was the level of burden by job category. Healthcare professionals were defined as physicians, nurses, pharmacists, administrators, care managers, and nursing home staff. To assess the degree of burden, participants were asked “Do you feel burdened by inquiries from health care professionals ? ” and their response was rated on a 5-point Likert scale (not at all, slightly, a little, a lot, and very much). The responses “a lot” and “very much” were combined and defined as “burdened.” To identify the causes of burden, factors of burden and inquiries were investigated. Results: Totally, 1,667 participants were recruited, of which 915 (54.9%) were included in the analysis (women: 62.6%). The participants had a median age of 38 years (interquartile range 31, 48), and worked as pharmacists for 12 years (interquartile range 5, 20). Nearly 13.5% of the respondents felt burdened by inquiries from healthcare professionals and 34.7% reported that physician inquiries were burdensome. The most common reason for feeling burdened was a lack of knowledge about the inquiries (77.3%). Conclusion: It was found that 13.5% of respondents felt burdened when dealing with inquiries from healthcare professionals to pharmacists. In particular, a high percentage of respondents felt burdened by inquiries from physicians. Further research is needed to clarify whether the introduction of a tool that matches the results of this study will reduce the burden of responding to inquiries.

Clinical Endoscopy 2024;57(3):375-383
Background/Aims:
Endoscopic self-expandable metal stent (SEMS) placement is currently the standard technique for treating unresectable malignant distal biliary obstructions (MDBO). Therefore, covered SEMS with longer stent patency and fewer migrations are required. This study aimed to assess the clinical performance of a novel, fully covered SEMS for unresectable MDBO.
Methods:
This was a multicenter single-arm prospective study. The primary outcome was a non-obstruction rate at 6 months. The secondary outcomes were overall survival (OS), recurrent biliary obstruction (RBO), time to RBO (TRBO), technical and clinical success, and adverse events.
Results:
A total of 73 patients were enrolled in this study. The non-obstruction rate at 6 months was 61%. The median OS and TRBO were 233 and 216 days, respectively. The technical and clinical success rates were 100% and 97%, respectively. Furthermore, the rate of occurrence of RBO and adverse events was 49% and 21%, respectively. The length of bile duct stenosis (<2.2 cm) was the only significant risk factor for stent migration.
Conclusions
The non-obstruction rate of a novel fully covered SEMS for MDBO is comparable to that reported earlier but shorter than expected. Short bile duct stenosis is a significant risk factor for stent migration.

Background/Aims:
Mechanical properties (MPs) and axial and radial force (AF and RF) may influence the efficacy and complications of self-expandable metallic stent (SEMS) placement. We measured the MPs of various SEMSs and examined their influence on the SEMS clinical ability.
Methods:
We evaluated the MPs of 29 types of 10-mm SEMSs. RF was measured using a conventional measurement device. AF was measured using the conventional and new methods, and the correlation between the methods was evaluated.
Results:
A high correlation in AFs was observed, as measured by the new and conventional manual methods. AF and RF scatterplots divided the SEMSs into three subgroups according to structure: hook-and-cross-type (low AF and RF), cross-type (high AF and low RF), and laser-cut-type (intermediate AF and high RF). The hook-and-cross-type had the largest axial force zero border (>20°), followed by the laser-cut and cross types.
Conclusions
MPs were related to stent structure. Hook-and-cross-type SEMSs had a low AF and high axial force zero border and were considered safest because they caused minimal stress on the biliary wall. However, the increase in RF must be overcome.

Objective:Only 44 of the 82 university medical schools in Japan have rehabilitation medicine departments, although rehabilitation medicine is one of the 19 basic specialties recognized by the Japanese Medical Specialty Board, and many medical doctors are concerned regarding selecting rehabilitation medicine as a basic specialty without sufficient education in the field. The “Let's Become a Physiatrist” Seminar has been organized since 2017 to eliminate such concerns, and this study aimed to investigate how these results are manifested in the number of majors.Methods:We examined the number of past attendees and tracked how many of them became rehabilitation medicine majors.Results:The number of seminar attendees over a 5-year period was 589. The number of on-demand viewers in FY2020 and FY2021, which were held via the web, was 554. A total of 116 of the 471 physicians who began specialty training in rehabilitation medicine after the seminar was planned attended or web viewed the seminar accounting for 24.63%.This percentage has been increasing each year, with 36.81% of the majors who applied in 2022 attending the seminar, and the number of multiple attendees also increased. The number of majors has increased significantly doubling to 144 in 2022 compared with 74 in 2018.Conclusion:In many cases, the seminar helped the attendees learn more about physiatrists and develop their thoughts while attending multiple times. Thus, they started their majors. Five years have passed since we started planning this seminar, and we believe that the results are now coming to fruition.

Although cardiac rehabilitation (CR) has been shown to improve exercise tolerance and prognosis in patients with cardiovascular diseases, there remains low participation in outpatient CR. This may be attributed to the patients’ busy schedules and difficulty in visiting the hospital due to distance, cost, avoidance of exercise, and severity of coronary disease. To overcome these challenges, many countries are exploring the possibility of remote CR. Specifically, there is increasing attention on the development of remote CR devices, which allow transmission of vital information to the hospital via a remote CR application linked to a wearable device for telemonitoring by dedicated hospital staff. In addition, remote CR programs can support return to work after hospitalization. Previous studies have demonstrated the effects of remote CR on exercise tolerance. However, the preventive effects of remote CR on cardiac events and mortality remain controversial. Thus, safe and effective remote CR requires exercise risk stratification for each patient, telenursing by skilled staff, and multidisciplinary interventions. Therefore, quality assurance of telenursing and multi-disciplinary interventions will be essential for remote CR. Remote CR may become an important part of cardiac management in the future. However, issues such as costeffectiveness and insurance coverage still persist.

Background:
Comparative analysis of virulence factors (VFs) between Pasteurella canis and Pasteurella multocida are lacking, although both cause zoonotic infections. We determined the virulence-associated genome sequence characteristics of P. canis and assessed the toxin gene prevalence unique to P. canis among clinical isolates of P. canis and P. multocida.
Methods:
We selected 10 P. canis and 16 P. multocida whole-genome sequences (WGSs) from the National Center for Biotechnology database. The VFanalyzer tool was used to estimate P. canis-characteristic VFs. Amino acid sequences of VFs were compared with multiple-aligned sequences. The genome structure containing P. canis-characteristic and adjacent loci was compared to the corresponding P. multocida genome structure. After designing primer sequences and assessing their accuracy, we examined the gene prevalence of the P. canis-characteristic VFs using PCR among clinical isolates of P. multocida and P. canis.
Results:
Using VFanalyzer, we found virulence-associated cytolethal distending toxin (cdt)A–cdtB–cdtC loci common to all P. canis WGSs that were not found in P. multocida WGSs. Similarities in the multiple alignments of CdtA–CdtB–CdtC amino acid sequences were found among the 10 P. canis WGSs. Shared or similar loci around cdtA–cdtB–cdtC were identified between the P. canis and P. multocida genome structures. The PCR-based cdtA–cdtB–cdtC prevalence differed for P. canis and P. multocida clinical isolates.
Conclusions
P. canis-specific cdtA–cdtB–cdtC prevalence was identified among clinical isolates. These three loci may be unique toxin genes and promising targets for the rapid identification of P. canis in clinical settings.

Purpose:
Patients with hematological malignancies are at an increased risk of severe infection with coronavirus disease 2019 (COVID-19). However, developing an adequate immune response after vaccination is difficult, especially in patients with lymphoid neoplasms. Since the long-term effects of the BNT162b2 vaccine are unclear, the humoral immune response 5 months after the two vaccinations in patients with hematological disorders was analyzed.
Materials and Methods:
Samples were collected from 96 patients vaccinated twice with BNT162b2 and treated with at least one line of an antitumor or immunosuppressive drug in our hospital from November 2021 to February 2022. Serum anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) spike (S) antibody titers were analyzed. Patients were age- and sex-matched using propensity matching and compared with a healthy control group. Patients with serum anti-SARS-CoV-2 S antibodies were defined as ‘responder’ if >50 U/mL. The patients had B-cell non-Hodgkin lymphoma (B-NHL), multiple myeloma, chronic myeloid leukemia, etc.
Results:
Patients had significantly low antibody levels (median, 55.3 U/mL vs. 809.8 U/mL; p<0.001) and a significantly low response rate (p<0.001). Multivariate analysis showed that patients with B-NHL, aged >72 years, were associated with a low response to vaccination. There were no significant differences between patients with chronic myeloid leukemia and healthy controls.
Conclusion
Our study shows that patients with hematological disorders are at risk of developing severe COVID-19 infections because of low responsiveness to vaccination. Moreover, the rate of antibody positivity differed between the disease groups. Further studies are warranted to determine an appropriate preventive method for these patients, especially those with B-NHL.

Objective:
The purposes of this trial were to demonstrate the feasibility and effectiveness of the hybrid of intracavitary and interstitial brachytherapy (HBT) for locally advanced cervical cancer patients in the phase I/II prospective clinical trial.
Methods:
Patients with FIGO stage IB2-IVA uterine cervical cancer pretreatment width of which was ≥5 cm measured by magnetic resonance imaging were eligible for this clinical trial. The protocol therapy included 30–30.6 Gy in 15–17 fractions of whole pelvic radiotherapy concurrent with weekly CDDP, followed by 24 Gy in 4 fractions of HBT and pelvic radiotherapy with a central shield up to 50–50.4 Gy in 25–28 fractions. The primary endpoint of phase II part was 2-year pelvic progression-free survival (PPFS) rate higher than historical control of 64%.
Results:
Between October 2015 and October 2019, 73 patients were enrolled in the initial registration and 52 patients proceeded to the secondary registration. With the median follow-up period of 37.3 months (range, 13.9–52.9 months), the 2- PPFS was 80.7% (90% confidence interval [CI]=69.7%–88%). Because the lower range of 90% CI of 2-year PPFS was 69.7%, which was higher than the historical control ICBT data of 64%, therefore, the primary endpoint of this study was met.
Conclusion
The effectiveness of HBT were demonstrated by a prospective clinical study. Because the dose goal determined in the protocol was lower than 85 Gy, there is room in improvement for local control. A higher dose might have been needed for tumors with poor responses.
