		                        			This study aimed to characterize physical function and functional capacity related to low muscle mass and sarcopenia in older women with low bone mass. In the study, 122 older women with bone loss were included and divided into three groups according to the presence or absence of muscle loss and sarcopenia; bone loss only, bone loss and muscle loss, and bone loss and sarcopenia groups. Multinomial logistic regression analysis was conducted using the three groups as dependent variables. Body mass index (BMI) (odds ratio; 0.566, 95% confidence interval; 0.431-0.742), Kihon checklist of “motor function” (odds ratio; 2.230, 95% confidence interval; 1.179-4.217), and “homebound” (odds ratio; 5.123, 95% confidence interval; 1.122-23.391) were extracted as relevant factors in the bone loss and sarcopenia group. In addition to low BMI, sarcopenia in older women with reduced bone mass is associated with lower “motor function” and “homebound” functional capacity.

		                        			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.

		                        			We report a case of redo mitral valve replacement (MVR) for a Björk-Shiley Delrin valve implanted 47 years previously. A 71-year-old man initially underwent MVR for mitral regurgitation at our hospital at the age of 16 years. Following the operation, follow-up examinations were performed at the outpatient clinic and annual transthoracic echocardiogram findings showed only mild mitral regurgitation, with no adverse events noted. However, a transthoracic echocardiogram examination performed 45 years after the operation revealed mild to moderate mitral regurgitation, while dyspnea with exertion was also noted at that time. As part of a more detailed examination, transesophageal echocardiogram results showed moderate transvalvular leakage. Redo MVR was subsequently performed under the diagnosis of prosthetic valve dysfunction. Analysis of the explanted prosthetic valve revealed wear of the Delrin disk, and widening of the gap between the disk and strut, which were presumed to be the cause of transvalvular leakage. A half century has passed since introduction of the Björk-Shiley valve and the present is a rare case of valve malfunction. Presented here are related details, along with a review of existing literature and results of Björk-Shiley valve use at our hospital.

		                        			Objective: The measurement of compounded topical medications’ uniformity is an important component of quality assessment. This study was aimed to evaluate appropriate mixing time for external preparations using a planetary centrifugal mixer.Methods: In order to evaluate the product uniformity of mixtures of five different steroid cream (Antebate®, Myser®, Methaderm®, Lidomex®, and Locoid®) with three different heparinoid oil-based cream (Hirudoid®, “Nichi-Iko” cream and “Nipro” cream), steroid cream and heparinoid oil-based cream (5 g each) were added into a 13 mL container and mixed using the mixer (NanKo Rentaro NRE-120®, THINKY) at rotation speed of 800 rpm and revolution speed of 2,000 rpm. We sampled 0.1 g of the mixture from three spots (top, middle, and bottom portions) of the container then, measured the steroid content by HPLC method. The yield value points of each cream and heparinoid oil-based cream were also measured by spread meter.Results: Our results showed that when the coefficient of variation (CV) is less than 15.2 %, a mixing time of at least 120 s was required to achieve proper mixing to obtain the permissible limit of steroid cream and heparinoid oil-based cream. Also the greater difference of the yield value between steroid cream and heparinoid oil-based cream tended to be mixed easier.Conclusions: These results suggest that the spread ability of steroid cream and heparinoid oil-based cream affects the mixing efficiency of a planetary centrifugal mixer.

		                        			Of the 511 patients who underwent high-resolution manometry, 394 who were evaluated for heartburn symptoms were examined. Patients subjected to high-resolution manometry were classified into 4 groups: outflow obstruction group, hypermotility group, hypomotility group, and normal motility group. Symptoms were evaluated using 3 questionnaires. Patient characteristics and symptoms for each EMD type were compared with those of the normal motility group.

The mean dysphagia score was significantly higher in each of the 3 EMD groups compared with those with normal motility. The mean acid reflux and dyspepsia scores were significantly lower in the outflow obstruction group (P < 0.05). The mean body mass index and median Brinkman index were significantly higher in the hypermotility group (P = 0.001 and P = 0.018, respectively), whereas the mean diarrhea and constipation scores were significantly lower in the hypomotility group (P < 0.05).

		                        			The results of our study indicate that different EMDs have distinct characteristics. Cigarette smoking and high body mass index were associated with esophageal hypermotility. Assessment of the dysphagia symptom scores may help identify patients with EMDs.

		                        			Objective: To examine the usefulness of inquiries made by hospital pharmacists.
Methods: This study was conducted a survey about the actual condition of inquiries at 5 hospitals.
Results: The prescriptions subjected to inquiry accounted for 1.5% of the inpatient prescriptions and 0.3% of the injection prescriptions.  In cases of “Incomplete entry in the prescription” for the subcategory of “Question about safety,” drug costs without the impact of pharmaceutical inquiries were calculated on the assumption that the concerned drugs should have been generally prescribed.  Our results showed that the total savings in medical costs were 30,673 yen for the inpatient prescriptions and 159,212 yen for injection prescriptions, which suggested that pharmaceutical inquiries are effective for saving medical costs for either type of prescriptions.  In the case of patients in whom adverse drug reactions (ADRs) might have occurred without prescription changes, medical cost savings realized by preventing ADRs were estimated using the Diagnosis Procedure Combination/Per-Diem Payment System (DPC/PDPS).  Our results showed that the savings were 1,428,710 yen for inpatient prescriptions (6 patients), which indicated that a large amount of medical costs was saved.
Conclusions: Our results suggested that similar to pharmaceutical inquiries made by community pharmacists, those made by hospital pharmacists not only result in the proper delivery of drug therapy but also are useful in terms of medical economics.

		                        			Introduction: Lifelong learning is important for physicians because of patient safety and the need to constantly improve the quality of medical practice. However, few studies have investigated the specific topics that are required.
Methods: We examined the lifelong learning needs of physicians by means of a self-administered questionnaire that was completed by 595 subjects, who were clinical practitioners working in Gunma Prefecture.
Results: Subjects of all ages needed lectures about the use of evidence-based medicine in medical examinations, clinical studies and the interpretation of epidemiological data, and diagnostic imaging. The younger subjects had a greater need for learning about clinical skills and techniques, such as advanced cardiac life support/intensive care life support, abdominal ultrasonic diagnosis, and cardiac ultrasonic diagnosis. Regarding the ideal times for these lectures, some physicians working at Gunma University Hospital expressed a preference for weekdays after normal business hours, while others preferred the weekends.
Discussion: The lifelong learning needs of physicians were clarified. Because physicians work on different shifts and at different institutions, scheduling training sessions that everyone can attend is difficult, especially for those who are off-campus. The timing of the training sessions, as well as the content of lectures, must be considered. Ideally, sessions should be held more than once to accommodate the busy schedules of physicians. We believe that providing an opportunity for lifelong learning will help attract more people to a career in medicine and thereby help address the physician shortage.

		                        			Introduction and Methods: An immediate effect of the physician shortage is the return to clinical work by physicians who had earlier left. Therefore, the needs of returning physicians were examined by means of a self-administered questionnaire. The subjects were clinicians working in Gunma Prefecture.
Results: About 50% of female physicians and 25% of male physicians had left clinical practice. The reasons given for leaving were “studying abroad” for most male physicians and “pregnancy and child-rearing” for most female physicians. More than 70% of physicians who had left clinical work felt uneasy about returning. The degree of anxiety after returning did not differ significantly between male and female physicians. Problems encountered by returning physicians involved “changes in medicines,” “changes and progress in technology and medical theories,” and deterioration of their “skills and techniques.” Moreover, returning physicians felt a need for increased “practical skills training.”
Discussion: Our study has clarified the needs of physicians returning to clinical work. The development and adoption of a simple system that will help physicians return to clinical practice is required.

		                        			1)Palliative care education by means e–learning was performed from December 3 to 25, 2009, for 1256 hospital medical staff. We used the same true–or–false questions to assess their understanding before and after the e–learning course.
2)Regardless of the staff member’s experience, the total scores on the test were higher after the course than before the course. Therefore, this e–learning course had an effect on basic knowledge for multiple types of medical staff.
3)The percentage of correct answers was particularly improved for questions about topics we had emphasized: drug dependence and side effects.
