Objective:
To evaluate the long-term efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer.
Methods:
This was the follow-up analysis of a phase 2, multicenter, open-label, single-arm study in Japanese women with homologous recombination-deficient, platinum-sensitive, relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of chemotherapy and were poly(ADP-ribose) polymerase inhibitor naïve. Participants received niraparib (starting dose, 300 mg) once daily in continuous 28-day cycles until objective disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was confirmed objective response rate (ORR), as assessed using Response Evaluation Criteria in Solid Tumors version 1.1. Safety evaluations included treatment-emergent adverse events (TEAEs).
Results:
20 patients were enrolled in the study and included in both efficacy and safety analyses. Median total study duration was 759.5 days. Median dose intensity was 201.3 mg/ day. Confirmed ORR was 60.0% (90% confidence interval [CI]=39.4–78.3); 2 patients had complete response and 10 patients had partial response. Median duration of response was 9.9 months (95% CI=3.9–26.9) and the disease control rate was 90.0% (95% CI=68.3–98.8).The most common TEAEs were anemia (n=15), nausea (n=12), and decreased platelet count (n=11). TEAEs leading to study drug dose reduction, interruption, or discontinuation were reported in 16 (80.0%), 15 (75.0%), and 2 patients (10.0%), respectively.
Conclusion
The long-term efficacy and safety profile of niraparib was consistent with previous findings in the equivalent population in non-Japanese patients. No new safety signals were identified.

Diabetes & Metabolism Journal 2024;48(3):440-448
Background:
Poor lifestyle habits may worsen nonalcoholic fatty liver disease (NAFLD), with progression to nonalcoholic steatohepatitis (NASH) and cirrhosis. This study investigated the association between glycemic control status and hepatic histological findings to elucidate the effect of glycemic control on NAFLD.
Methods:
This observational study included 331 patients diagnosed with NAFLD by liver biopsy. Effects of the glycemic control status on histological findings of NAFLD were evaluated by comparing the following four glycemic status groups defined by the glycosylated hemoglobin (HbA1c) level at the time of NAFLD diagnosis: ≤5.4%, 5.5%–6.4%, 6.5%–7.4%, and ≥7.5%.
Results:
Compared with the lowest HbA1c group (≤5.4%), the higher HbA1c groups (5.5%–6.4%, 6.5%–7.4%, and ≥7.5%) were associated with advanced liver fibrosis and high NAFLD activity score (NAS). On multivariate analysis, an HbA1c level of 6.5%– 7.4% group was significantly associated with advanced fibrosis compared with the lowest HbA1c group after adjusting for age, sex, hemoglobin, alanine aminotransferase, and creatinine levels. When further controlling for body mass index and uric acid, total cholesterol, and triglyceride levels, the higher HbA1c groups were significantly associated with advanced fibrosis compared with the lowest HbA1c group. On the other hand, compared with the lowest HbA1c group, the higher HbA1c groups were also associated with a high NAS in both multivariate analyses.
Conclusion
Glycemic control is associated with NAFLD exacerbation, with even a mild deterioration in glycemic control, especially a HbA1c level of 6.5%–7.4%, contributing to NAFLD progression.

Journal of Neurogastroenterology and Motility 2024;30(2):229-235
Background/Aims:
Although certain allergic diseases have been reported to be associated with the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS), it is unclear whether the presence of multiple allergic diseases further increases the prevalence of FD and IBS.The aim of this study is to determine this issue in young people.
Methods:
A cohort of 8923 Japanese university students was enrolled and diagnoses of FD and IBS were confirmed using Rome III criteria.Allergic disorders diagnosed at medical institutions were obtained by means of a self-administered questionnaire.
Results:
The prevalence of FD, IBS, and their overlap was found to be 1.9%, 6.5%, and 1.1%, respectively. Pollen allergy was independently positively correlated with FD, IBS, and overlap of FD and IBS. Allergic rhinitis was positively linked to IBS. Drug allergy was positively associated with FD. The presence of multiple allergic diseases was positively correlated with FD and IBS (FD: adjusted OR for 2 allergic diseases: 1.95 [95% CI, 1.24-2.98], P for trend = 0.003; and IBS: adjusted OR for 1 allergic disease: 1.40 [95% CI, 1.15-1.69], 2 allergic diseases 1.47 [95% CI, 1.12-1.91], and 3 or more allergic diseases: 2.22 [95% CI, 1.45-3.28], P for trend = 0.001). Additionally, the concomitant existence of multiple allergic diseases was also demonstrated to have a trend that correlated with the overlap of FD and IBS (P for trend = 0.018).
Conclusion
Allergic disease multimorbidity is positively correlated with the prevalence of FD and IBS in a young population.

Objective: To evaluate the efficacy of fan therapy for the relief of dyspnea in patients with chronic progressive disease. Methods: A systematic electronic database search of all available articles published before October 23, 2019 was conducted using Ichushi-Web of the Japan Medical Abstract Society databases, CENTRAL, EMBASE, and MEDLINE. In addition, a hand-search for updates was performed using PubMed on June 30, 2020 and December 7, 2021. The inclusion criteria were: 1) any RCTs comparing the effect of fan therapy with any other intervention, and 2) patients aged ≥18 years. Exclusion criteria were: 1) duplicate references, and 2) conference presentations. Results: We identified 110 studies, of which 10 met our criteria for inclusion. Finally, five studies were used in the meta-analysis. Fan therapy significantly improved dyspnea in patients with chronic progressive disease compared to control groups with a standardized mean difference of −1.43 (95% confidence interval: −2.70 to −0.17, I2=94%, p<0.0001). Conclusion: Fan therapy was found to be effective in reducing dyspnea in chronic progressive disease.

Journal of Gynecologic Oncology 2021;32(2):e16-
Objective:
To evaluate the efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer.
Methods:
This Phase 2 open-label, single-arm study enrolled Japanese women with homologous recombination deficiency-positive relapsed, high-grade serous ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of therapy. The starting dose of niraparib was 300 mg administered once daily in continuous 28-day cycles until objective progressive disease, unacceptable toxicity, consent withdrawal or discontinuation. The primary endpoint, objective response rate (ORR), was assessed by the investigator using RECIST version 1.1. Safety evaluations included the incidence of treatment-emergent adverse events (TEAEs), including serious TEAEs.
Results:
Twenty women were enrolled and the confirmed ORR in the full analysis set (FAS) was 35.0% (7/20), consisting of 1 complete response and 6 partial responses. Disease control rate in the FAS was 90.0%. The most frequently reported TEAEs (>50%) were anemia, nausea, and platelet count decreased. One patient (5.0%) had TEAEs leading to discontinuation of niraparib whereas reductions or interruptions were reported in 14 (70.0%) and 15 (75.0%) patients, respectively. The median dose intensity (202.9 mg daily) corresponded to a relative dose intensity of 67.6%.
Conclusion
Efficacy and safety of niraparib in heavily pretreated Japanese women was comparable to that seen in an equivalent population of non-Japanese women. No new safety signals were identified.

Objectives: This study aimed to clarify the present system of palliative care at general hospitals, and to examine the factors contributing to the opioid consumption. Methods: We surveyed the palliative care system using a self-administered questionnaire, which was mailed to 37 general hospitals in Southern and Southwestern wards, Tokyo. Multiple regression analyses were used to identify the associations between explanatory variables and the opioid consumption. Results: Valid responses were obtained from 18 hospitals (response rate: 48.6%). 35% of the general hospitals didn’t have a palliative care team and most hospitals had no specialists. In multivariate analyses, factors associated with the opioid consumption were pharmacists with speciality of pharmaceutical palliative care, physicians joined the palliative care education program based on the Cancer Control Act of Japan, and the number of physicians’ correct answers of questions regarding palliative care. Conclusion: The survey showed that the higher consumption of opioids is significantly associated with the number of health care workers who have knowledge of palliative care. Our study suggested that the arrangement of palliative care experts might decrease the differences in the opioid consumption between general hospitals.

For the visualization of diploma policy (DP) achievement, we analyzed grade point (GP) of classes on subjects associated with competency (CPT). Visualization of students’ DP achievement became possible. When we divided DP into eight items, which responded to each CPT respectively and showed a radar chart with a calculation of the average grade points (AGP) in categorized class subjects. AGP for every item was compared among all students who were classified into six types, Those classifications were as follows all excellent evaluation, confined excellent evaluation, average evaluation high and low evaluation mixture, confined low evaluation and all low evaluation when compared with the average. We administered a self-check DP achievement questionnaire to the students and compared the results with AGP, Students were then classified into four types, self-underestimate, self-overestimate, appropriate low evaluation, and appropriate high evaluation. There were many female students in the self-underestimate type and many male students in the self-overestimate types. AGP analysis of class subjects associated with CPT is useful for the visualization of DP achievement and shows promise as a new student evaluation.
