Objective: The package inserts are official clinical decision-making documents that provide pharmacological treatment information. However, it has been noted that package inserts on perinatal drug usage differ greatly from expert opinions. This study identified Japanese package insert drugs that are contraindicated for pregnant women and compared them to foreign risk categories.Methods: The survey included 19,022 drugs on the drug pricing list as of April 2022, with package inserts available on the Pharmaceuticals and Medical Devices Agency website. We retrieved the package inserts with the word “pregnant” in the “Contraindications” section and reviewed the descriptions to exclude those that satisfied the exclusion criteria. We also checked the foreign risk categories of contraindicated ingredients for pregnant women. This study used the Australian Therapeutic Goods Administration’s categorization for prescribing medicines in pregnancy (the TGA classification).Results: Of the 19,022 medicines studied, 4,111 (21.6%) were contraindicated for pregnant women. Conversely, 19 (5.1%) ingredients categorized under the relatively safe TGA classifications A, B1, and B2 were also contraindicated for pregnant Japanese women.Conclusion: This study revealed that Japanese package inserts contraindicate over 20% of drugs for pregnant women. On the other hand, some forbidden ingredients did not match the foreign risk categories. Therefore, healthcare professionals should be aware of the limitations of Japanese package inserts concerning pregnant women and make careful decisions based on both package inserts and additional drug information.

Introduction: Pancreatic cancer often recurs as local recurrence or peritoneal dissemination, causing severe abdominal and back pain. We report a case of postoperative skull metastasis of pancreatic cancer that caused headache and was treated effectively with radiotherapy. Case: A 67-year-old woman underwent surgery for pancreatic cancer. She had epigastric pain due to local recurrence and peritoneal dissemination, which was controlled with loxoprofen and fentanyl transdermal patch. She had right-sided headache, which gradually increased in intensity, but lacked intracranial hypertension and focal neurological symptoms. Acetaminophen and Goreisan did not provide adequate pain relief. Although CT showed no brain or bone metastasis, MRI showed metastasis in the right frontal bone. Palliative radiotherapy was administered. Subsequently, headache decreased from 7–8/10 to 2–3/10 on the Numerical Rating Scale. Conclusion: Skull metastases in cancer patients may be diagnosed using MRI, even when they remain undetectable by CT.

Objective:
To investigate the impact of body mass index (BMI) and exercise habits on readmission rates among older patients with heart failure.
Methods:
Ninety-seven older patients admitted for heart failure (median age: 81 years; 57.7% male) were included in the study. Patients were categorized into four groups based on the presence or absence of lower BMI and/or the absence of exercise habits. Lower BMI was defined as BMI<20.3 kg/m2 at discharge and exercise habits were defined as engaging in 30 or more minutes of moderate or vigorous exercise at least once a week. The primary outcome was all-cause readmission during the 1-year follow-up period.
Results:
The patients were distributed across four groups: lower BMIon-exerciser (n=24, 24.7%), lower BMI/exerciser (n=22, 22.7%), non-lower BMIon-exerciser (n=21, 21.6%), and non-lower BMI/exerciser (n=30, 30.9%). Forty-six patients (47.4%) experienced readmission during the 1-year follow-up period. In a cox proportional hazard analysis, non-lower BMI/exerciser remained an independent prognostic factor even after adjusting for confounding factors (non-lower BMI/exerciser vs. lower BMIon-exerciser: hazard ratio, 0.26; 95% confidence interval, 0.08–0.83; p=0.022).
Conclusion
The coexistence of non-lower BMI and regular exercise habits may reduce readmission during the 1-year in older patients with heart failure. Therefore, it is imperative to conduct appropriate nutritional assessments for patients with lower BMI at discharge. Additionally, promoting and monitoring sustained physical activity after discharge is crucial for older patients with heart failure.

Purpose:
Autoregulation of retinal vessels is stronger than that of choroidal vessels. This study aimed to use laser speckle flowgraphy to determine the time course of changes in retinal hemodynamics of healthy eyes after a cold pressor test.
Methods:
This prospective study included 44 right eyes of 44 healthy volunteers (age, 21.7 ± 5.0 years). The mean blur rate, which is a quantitative index of the relative blood flow velocity in the retina, was measured using laser speckle flowgraphy. The vessel average of mean blur rate at the optic nerve head, intraocular pressure, systolic blood pressure, diastolic blood pressure, mean blood pressure, heart rate, and ocular perfusion pressure were evaluated at baseline, immediately after the cold pressor test, and 10, 20, and 30 minutes after the test.
Results:
Immediately after the test (0 minutes), systolic blood pressure, diastolic blood pressure, mean blood pressure, and ocular perfusion pressure were significantly increased compared with those at baseline; however, no changes were observed at 10, 20, and 30 minutes after the test. In contrast, intraocular pressure, heart rate, and the vascular mean blur rate values at the optic nerve head did not change throughout the course of the study.
Conclusions
Sympathetic hyperactivity induced by the cold pressor test increased systemic circulatory dynamics, but not retinal circulatory hemodynamics, suggesting the involvement of vascular autoregulation.

BACKGROUND:
Internal medicine (IM) doctors in Japan play the role of primary care physicians; however, the shortage of rural physicians continues. This study aims to elucidate the association of age, sex, board certification, type of work, and main clinical work with the retention or migration of IM doctors to rural areas.
METHODS:
This retrospective cohort study included 82,363 IM doctors in 2010, extracted from the national census data of medical doctors. The explanatory variables were age, sex, type of work, primary clinical work, and changes in board certification status. The outcome was retention or migration to rural areas. The first tertile of population density (PD) of municipalities defined as rural area. After stratifying the baseline ruralities as rural or non-rural areas, the odds ratios (ORs) of the explanatory variables were calculated using generalized estimation equations. The analyses were also performed after age stratification (<39, 40-59, ≥60 years old).
RESULTS:
Among the rural areas, women had a significantly higher OR for retention, but obtaining board certification of IM subspecialties had a significantly lower OR. Among the non-rural areas, physicians who answered that their main work was IM without specific subspecialty and general had a significantly higher OR, but obtaining and maintaining board certification for IM subspecialties had a significantly lower OR for migration to rural areas. After age stratification, the higher OR of women for rural retention was significant only among those aged 40-59 years. Those aged under 40 and 40-59 years in the non-rural areas, who answered that their main work was IM without specific subspecialty had a significantly higher OR for migration to rural areas, and those aged 40-59 years in the rural areas who answered the same had a higher OR for rural retention.
CONCLUSIONS
Obtaining and maintaining board certification of IM subspecialties are possible inhibiting factors for rural work, and IM doctors whose main work involves subspecialties tend to work in non-rural areas. Once rural work begins, more middle-aged female IM doctors continued rural work compared to male doctors.

Clinical Endoscopy 2023;56(1):107-113
Background/Aims:
Immune checkpoint blockade has recently been reported to be effective in treating microsatellite instability (MSI)-high tumors. Therefore, sufficient sampling of histological specimens is necessary in cases of unresectable pancreatic cancer (UR-PC). This multicenter study investigated the efficacy of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) using a Franseen needle for MSI evaluation in patients with UR-PC.
Methods:
A total of 89 patients with UR-PC who underwent endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) or EUS-FNB using 22-G needles at three hospitals in Japan (2018–2021) were enrolled. Fifty-six of these patients (FNB 23 and FNA 33) were followed up or evaluated for MSI. Patient characteristics, UR-PC data, and procedural outcomes were compared between patients who underwent EUS-FNB and those who underwent EUS-FNA.
Results:
No significant difference in terms of sufficient tissue acquisition for histology was observed between patients who underwent EUS-FNB and those who underwent EUS-FNA. MSI evaluation was possible significantly more with tissue samples obtained using EUS-FNB than with tissue samples obtained using EUS-FNA (82.6% [19/23] vs. 45.5% [15/33], respectively; p<0.01). In the multivariate analysis, EUS-FNB was the only significant factor influencing the possibility of MSI evaluation.
Conclusions
EUS-FNB using a Franseen needle is desirable for ensuring sufficient tissue acquisition for MSI evaluation.

The purpose of this study was to clarify the changes in the sense of difficulty hospital staff felt toward palliative care before and after a palliative care team of the pediatric hospital started in-hospital consultation. A self-administered questionnaire about the difficulty, consisting of 21 items in five areas, was used to conduct a survey in 2015 for the pre-consultation period, and in 2018 for the post-consultation period. Responses were obtained from 222 people in the pre-consultation period (response rate of 70.9%) and from 384 people in the post-consultation period (response rate of 87.3%). Over 70% of the respondents were nurses and midwives. A lower sense of difficulty was observed in three of the items including “relief of painful symptoms”, “family care during caregiving”, and “support when oneself and surrounding staff feeling inadequate and lost”. Further, a significant decrease was observed in the sense of difficulty in six items reported by nurses and midwives in departments receiving the interventions. Eleven of the 16 cases in which the palliative care team intervened involved multiple requests for intervention for 2 patients with pain control difficulties, suggesting that the consultation activities contributed to the decrease in the sense of difficulty experienced by nurses and midwives.

Objective: In our previous study, we revealed that articles on "dangerous drugs" in weekly magazines are inadequate and incomplete with respect to scientific validity, and that there may be many aspects that need to be improved. Next, the extent to which medical professionals, including doctors, pharmacists, and nurses, received consultations by patients owing to such media reports and what countermeasures are implemented requires clarification. In the present study, as a first step, we performed a questionnaire survey of community pharmacists to clarify the occurrence of such consultations.Methods: A questionnaire survey was conducted among 698 community pharmacists. The survey was conducted over 10 days from December 8 to 17, 2021.Results: Out of the 698 community pharmacists, 545 responded (response rate: 78.1%). Of these, 323 (59.3%) had experienced consultations from patients owing to media reports on the dangers of drugs. Of the 323 respondents, 215 (66.6%) had experienced these consultations less than five times. In contrast, 83 respondents (25.7%) reported more than 10 such consultations. Of the 545 respondents, 190 (34.9%) responded that they routinely perform measures to deal with media reports on the dangers of drugs. The most common routine measure was the "regular checking of various media sources (including preparation of responses when receiving consultation requests)."Conclusion: Our results indicated that more than half of the community pharmacists had experienced receiving consultations from patients, although only approximately 30% were adopting routine measures. This suggests that community pharmacists have been affected to some extent by these media reports, and that further countermeasures need to be implemented.

Objective: Recently, special features on “dangerous” prescription drugs have been frequently published in few mass media platforms, such as weekly magazines. However, to our knowledge, there have been no prior studies, systematically organizing and evaluating the contents of these articles (e.g., drugs and their side effects that are reported). In this study, we aimed to evaluate the relevance of the information on “dangerous drugs” that was published in weekly magazines using the modified “Media Doctor” instrument.Methods: We extracted articles on “dangerous” prescription drugs from 10 weekly magazines for which the table of contents of previous issues are available on their official websites. Information regarding the target drugs and their classifications was compiled and organized. The relevance of the extracted news articles was assessed by two independent evaluators. The evaluation index was based on the modified “Media Doctor” instrument, and 9 evaluation criteria were used to assign the following categories: satisfactory, unsatisfactory, or not applicable.Results: A total of 1,064 articles were screened, and 19 articles were selected for further evaluation. A total of 179 drugs (belonging to 34 drug classes) were listed. The most frequently mentioned class of drugs included hypnotics and sedatives, and the most frequently listed was triazolam. Of the 19 articles, 11 had zero items that were judged satisfactory by both the evaluators. The number of unsatisfactory items was widely distributed, but in 11 of the 19 articles, five and more items were judged unsatisfactory by both the evaluators.Conclusion: We revealed that a wide variety of drugs have been termed as “dangerous” by weekly magazines. Additionally, we found that these articles were inadequate and incomplete with respect to scientific validity, and that there are many aspects that require further improvement.

Background:
and Purpose To assess the long-term outcomes of intracranial dural arteriovenous fistula (DAVF) treated with stereotactic radiosurgery (SRS) alone or embolization and SRS (Emb-SRS) and to develop a grading system for predicting DAVF obliteration.
Methods:
This multi-institutional retrospective study included 200 patients with DAVF treated with SRS or Emb-SRS. We investigated the long-term obliteration rate and obliteration-associated factors. We developed a new grading system to estimate the obliteration rate. Additionally, we compared the outcomes of SRS and Emb-SRS by using propensity score matching.
Results:
The 3- and 4-year obliteration rates were 66.3% and 78.8%, respectively. The post-SRS hemorrhage rate was 2%. In the matched cohort, the SRS and Emb-SRS groups did not differ in the rates of obliteration (P=0.54) or post-SRS hemorrhage (P=0.50). In multivariable analysis, DAVF location and cortical venous reflux (CVR) were independently associated with obliteration. The new grading system assigned 2, 1, and 0 points to DAVFs in the anterior skull base or middle fossa, DAVFs with CVR or DAVFs in the superior sagittal sinus or tentorium, and DAVFs without these factors, respectively. Using the total points, patients were stratified into the highest (0 points), intermediate (1 point), or lowest (≥2 points) obliteration rate groups that exhibited 4-year obliteration rates of 94.4%, 71.3%, and 60.4%, respectively (P<0.01).
Conclusions
SRS-based therapy achieved DAVF obliteration in more than three-quarters of the patients at 4 years of age. Our grading system can stratify the obliteration rate and may guide physicians in treatment selection.
