Tirzepatide has demonstrated greater efficacy than semaglutide in improving glycemic control and reducing body weight in patients with type 2 diabetes mellitus (T2DM). However, the optimal tirzepatide dose following a switch from 1.0 mg of semaglutide remains unclear. This retrospective study included 15 T2DM patients who switched to tirzepatide due to inadequate weight loss. All patients started tirzepatide at 2.5 mg, with escalation to either 7.5 mg (n=10) or 10 mg (n=5). Changes in glycated hemoglobin (HbA1c) and body weight were assessed over a 3-month period. The 10 mg group experienced a significant reduction in HbA1c (−0.7%±0.3%, P<0.01) and a non-significant trend toward weight loss (−6.6±5.4 kg, P=0.07). In contrast, no significant changes were observed in the 7.5 mg group. There were no statistically significant differences between groups. Since 10 mg of tirzepatide significantly improved glycemic control after switching from 1.0 mg of semaglutide, early escalation to 10 mg may be beneficial for patients who respond inadequately to semaglutide.

Objective:
This multi-center retrospective study aimed to clarify the characteristics, diagnostic accuracy, treatment outcomes, and prognostic factors of uterine serous carcinoma (USC) in Japanese women.
Methods:
The medical records of 193 patients who were treated between 2006 and 2008 at 24 participating institutions in the Japanese Clinical Oncology Group were examined, and pathological slides of 188 patients were re-checked through central pathology review (CPR), hematoxylin-eosin staining, and immunohistochemistry.
Results:
USC was confirmed in 144 of the 188 (76.6%) patients using CPR, and only 50% were correctly diagnosed preoperatively. Forty-three patients were diagnosed with non-serous carcinoma, whereas one patient had metastasis from another organ. The average age was 65.7 years, and 19% of patients had a history of other cancers. The incidence of stage III–IV disease was 52.8%, and lymph node metastasis was found in 28.5% of patients. Extrauterine spread and distant metastasis occurred in 39% and 14% of patients, respectively. The 2-year overall survival and progression-free survival (PFS) rates were 56% and 42%, respectively. The PFS of patients with stage I and II who underwent complete staging surgery was 92.3%, and that of those without lymph node dissection or omentectomy was 33.3%. Patients with USC had a significantly worse prognosis than 43 patients with non-serous carcinoma.
Conclusion
USC in Japanese women has characteristics different from those of endometrioid carcinoma, worse prognosis, and is difficult to diagnose preoperatively. Complete surgical staging is necessary even for early-stage disease. Additionally, new adjuvant treatment strategies, including molecular targeted therapy, should be explored.

Objective: To keep medical costs down, it is important to promote the use of generic drugs at pharmacies, where prescription volumes are high. However, many parents do not opt for generic drugs. This study examines the effectiveness of pharmacists’ explanations to parents, with the aim of promoting the use of generic drugs among young patients under the age of 20.Method: A questionnaire-based survey was conducted from November 25 to December 1, 2019, at 129 pharmacies.Results: During the survey period, 91 pharmacies received 4,491 prescriptions from young patients. The percentage of generic drugs dispensed per prescription was lower for the young patients than for adult patients (65.4% vs. 70.4%; p < 0.001). Statistically, the percentage of prescriptions dispensed using generic drugs was higher in pharmacies that explained costs, equivalence of quality and efficacy, safety, side effects, and the trial system (divided dispensing), compared to pharmacies that did not use these explanations. Conversely, the percentage of prescriptions dispensed using generic drugs was lower at pharmacies that explained dosage form and ease of swallowing. Many pharmacies explained the equivalence of quality and efficacy (85.7%), with many questions from parents (82.4%). However, only a few pharmacies explained the trial system (divided dispensing) (1.1%), with no questions raised by parents (0.0%).Conclusion: This study found that pharmacists’ explanations are effective in promoting the use generic drugs for young patients. However, there is a lack of awareness among parents about the trial system (divided dispensing), and public institutions and pharmacists are not responding appropriately. To promote generic drug usage among young patients, it is important to develop educational tools regarding the trial system (divided dispensing), create awareness campaigns for parents, and revise medical fee. Furthermore, to ensure safe drug therapy, pharmacists should also provide information on the appearance and taste of generic drugs.

Objective: The proportion of young patients in Japan in whom generic drugs are used is lower than that of other age groups. To promote the use of generic drugs in young patients, we need to change the parents’ attitude toward generic drugs. Therefore, we aimed to contribute to the maintenance and reform of the Japanese social security system by investigating the effects of parent’s sex, patient’s age, and use of the children’s medical expense subsidy system on the selection of generic drugs. Method: We surveyed parents of young patients (<20 years) whose prescriptions were filed at pharmacies from November 25 to December 1, 2019. Results: Of the 712 valid questionnaires retrieved, 74.3% of parents reported using generic drugs for young patients. Approximately 92.2% of the parents reported using the children’s medical expense subsidy system. The highest (51.4%) reason for switching to generics was “recommendation from a pharmacist, etc.” Cognitive methods using online content were higher among male parents than among female parents (28.0% vs. 11.5% ; P<0.001). Regarding catchphrases that make them want to hear, female parents were more likely to hear about generic drugs than male parents were if the catchphrases quality and safety were used (38.1% vs. 23.8% ; P=0.007). Compared to parents of 7-19-year old children (6.8%), parents of 0-6-year old children (13.1%) reportedly switched to generic drugs because they were easier to ingest (P=0.022). Conclusion: Recommendations from medical professionals such as pharmacists are effective in convincing parents of young patients to switch to generic drug use. To promote the use of generic drugs in young patients, in addition to explaining and publicizing its financial benefits, pharmacists need to explain the added value of generic drugs such as the ingenuity of its dosage form. In addition, it is essential to adopt a multifaceted approach that considers the parents’ background including (1) publicity using the internet for male parents, (2) reaching out to female parents with preschool children, (3) increasing publicity using tickets for children’s medical expenses subsidy system, and (4) drug education that matches the growth of children.

Background / Purpose: The aim of this study was to analyze the relationship between metacognition and mental health among first-year Japanese medical students at several months after admission. Method: A questionnaire survey was conducted on first-year medical students at a private medical university. We used the Adults' Metacognition Scale to measure metacognition and the Japanese version of the 12-item General Health Questionnaire (GHQ-12) to measure mental health status. Results: The data from 80 students were analyzed. The total metacognition score and the subscale monitoring score were negatively correlated with the GHQ-12 total score and were significantly different between the poor mental health group and the good mental health group. Discussion: The results suggest that students in poor mental health status were considered to have weak metacognition, especially monitoring.

Journal of Neurogastroenterology and Motility 2022;28(1):53-61
Background/Aims:
Gastric acid secretion is suspected to be a pivotal contributor to the pathogenesis of functional dyspepsia. The present study investigates the potential association of the gastric acid secretion estimated by measuring serum pepsinogen with therapeutic responsiveness to the prokinetic drug acotiamide.
Methods:
Dyspeptic patients consulting participating clinics from October 2017 to March 2019 were prospectively enrolled in the study. The dyspeptic symptoms were classified into postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). Gastric acid secretion levels were estimated by the Helicobacter pylori infection status and serum pepsinogen using established criteria and classified into hypo-, normo-, and hyper-secretion. Each patient was then administered 100 mg acotiamide thrice daily for 4 weeks, and the response rate to the treatment was evaluated using the overall treatment efficacy scale.
Results:
Of the 86 enrolled patients, 56 (65.1%) and 26 (30.2%) were classified into PDS and EPS, respectively. The estimated gastric acid secretion was not significantly different between PDS and EPS. The response rates were 66.0% for PDS and 73.1% for EPS, showing no significant difference. While the response rates were stable, ranging from 61.0% to 75.0% regardless of the estimated gastric acid secretion level among subjects with PDF, the rates were significantly lower in hyper-secretors than in non-hyper-secretors among subjects with EPS (42.0% vs 83.0%, P = 0.046).
Conclusion
Although acotiamide is effective for treating EPS as well as PDS overall, the efficacy is somewhat limited in EPS with gastric acid hypersecretion, with gastric acid suppressants, such as proton pump inhibitors, being more suitable.

Clinical Psychopharmacology and Neuroscience 2021;19(4):773-779
Objective:
While antipsychotics are necessary for relapse prevention in the treatment of schizophrenia in general, some minority of patients may be maintained without continuous antipsychotic treatment. However, the characteristics of such patients are not well known and previous reports have not evaluated key elements such as physical comorbidities and functioning.
Methods:
Among 635 patients with schizophrenia who participated in a 12-year follow-up, those who were maintained without antipsychotic treatment for at least one year after the study were investigated. The patients underwent comprehensive assessments, including Positive and Negative Syndrome Scale (PANSS) for psychopathology, Cumulative Illness Rating Scale for Geriatrics (CIRS-G) for physical comorbidities, and Functional Assessment for Comprehensive Treatment of Schizophrenia (FACT-Sz), Barthel Index, and EuroQoL five dimensions (EQ5D) for function.
Results:
Six patients were included (mean ± standard deviation age, 66.8 ± 17.4 years; 4 inpatients). The four inpatients were old (77.8 ± 4.8 years) and chronically ill (duration of illness, 49.3 ± 12.5 years) with a high PANSS score (total score, 118.0 ± 9.8; negative syndrome subscale, 41.3 ± 6.9), low functioning (FACT-Sz, 9.8 ± 3.6; Barthel Index, 8.8 ± 9.6), and serious physical comorbidities (CIRS-G, 15.5 ± 1.1). By contrast, the two outpatients were relatively young (45.0 ± 12.0 years) and clinically in good condition (PANSS total score, 44.5 ± 0.5; Barthel Index, 100 for both; EQ5D, 0.85 ± 0.04).
Conclusion
Although the number is limited, two types of patients with schizophrenia were identified who were free from ongoing antipsychotic treatment; 1) older chronic inpatients with serious physical comorbidities, and 2) younger outpatients with milder impairments. Future explorations are needed to identify those who will be successfully withdrawn from continuous antipsychotic treatment.

OBJECTIVE:
This study estimated the effects of weekend and off-hour childbirth and the size of perinatal medical care center on the incidence of cerebral palsy.
METHODS:
The cases were all children with severe cerebral palsy born in Japan from 2009 to 2012 whose data were stored at the Japan Obstetric Compensation System for Cerebral Palsy database, a nationally representative database. The inclusion criteria were the following: neonates born between January 2009 and December 2012 who had a birth weight of at least 2000 g and gestational age of at least 33 weeks and who had severe disability resulting from cerebral palsy independent of congenital causes or factors during the neonatal period or thereafter. Study participants were restricted to singletons and controls without report of death, scheduled cesarean section, or ambulance transportation. The controls were newborns, randomly selected by year and type of delivery (normal spontaneous delivery without cesarean section and emergency cesarean section) using a 1:10 case to control ratio sampled from the nationwide Japan Society of Obstetrics and Gynecology database.
RESULTS:
A total of 90 cerebral palsy cases and 900 controls having normal spontaneous delivery without cesarean section were selected, as were 92 cerebral palsy cases and 920 controls with emergent cesarean section. A significantly higher risk for cerebral palsy was found among cases that underwent emergent cesarean section on weekends (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.06-2.81) and during the night shift (OR 2.29, 95% CI 1.30-4.02). No significant risk was found among normal spontaneous deliveries on weekends (OR 1.63, 95% CI 0.97-2.73) or during the quasi-night shift (OR 1.26, 95% CI 0.70-2.27). Regional perinatal care centers showed significantly higher risk for cerebral palsy in both emergent cesarean section (OR 2.35, 95% CI 1.47-3.77) and normal spontaneous delivery (OR 2.92, 95% CI 1.76-4.84).
CONCLUSION
Labor on weekends, during the night shift, and at regional perinatal medical care centers was associated with significantly elevated risk for cerebral palsy in emergency cesarean section.

Hideaki MURAOKA ; Toshiaki SUZUKI
The Japanese Journal of Rehabilitation Medicine 2020;57(2):174-182
Objective:To investigate the effects of being instructed to use a squat method on posture and the joints involved in the pelvic position.Methods:The subjects were 15 healthy men (mean age, 23.8 ± 1.0 years).We set free and squat conditions as the measurement tasks and instructed the subjects to lift an object from the floor. Differences in joint angles between the two conditions at the time the object left the floor were examined using a corresponding t test. To assess the joints that affect the pelvic anterior tilt angle, lumbar and limb joint angles and the correlation coefficient between them were calculated.Results:In the squat condition, the extension angles of the thoracic vertebrae, upper and lower thoracolumbar transitional vertebrae, and upper lumbar vertebrae;the pelvic posterior tilt angle;flexion angles of the hip and knee joints;and dorsiflexion angle of the ankle joint increased. The pelvic anterior tilt angle was related to the knee and ankle joint angles in both conditions.Conclusion:Instructions to use a squat method increased the trunk extension and leg flexion angles. In both conditions, the knee and ankle joints affect the pelvic anterior tilt angle.

Journal of Gynecologic Oncology 2020;31(6):e94-
Objective:
In this study we sought to investigate the clinical factors that affect postprogression survival (PPS) in patients with recurrent or persistent clear cell carcinoma (CCC).We utilized the JGOG3017/Gynecological Cancer InterGroup data to compare paclitaxel plus carboplatin (TC) and irinotecan plus cisplatin (CPT-P) in the treatment of stages I to IV CCC.
Methods:
We enrolled 166 patients with recurrent or persistent CCC and assessed the impact of variables, including platinum sensitivity, treatment arm, crossover chemotherapy, primary stage, residual tumor at primary surgery, performance status, ethnicity, and tumor reduction surgery at recurrence on the median of PPS in patients with recurrent or persistent CCC.
Results:
A total of 77 patients received TC, and 89 patients received CPT-P. The median PPS for patients with platinum-resistant disease was 10.9 months, compared with 18.8 months for patients with platinum-sensitive disease (hazard ratio [HR]=1.88; 95% confidence interval [CI]=1.30–2.72; log-rank p<0.001). In the multivariate analysis, the platinum sensitivity (resistant vs. sensitivity; HR=1.60; p=0.027) and primary stage (p=0.009) were identified as independent predictors of prognosis factors for PPS in recurrent or persistent CCC.
Conclusions
Our findings revealed that platinum sensitivity and primary stage are clinical factors that significantly affect PPS in patients with recurrent or persistent CCC as wellas other histologic subtypes of ovarian cancer. PPS in patients with recurrent CCC should establish the basis for future clinical trials in this population.
