Gait disturbance is a serious problem in Parkinson's disease (PD). Exercise therapy is used to alleviate this complaint. We investigated the effects of a videotaped arm swinging-based home exercise program on gait in PD patients. The subjects included 25 outpatients aged between 55 and 77 years (average age 68.9 years) with PD in Hoehn and Yahr stages II-IV. We prepared a master video tape in which a trainer was shown to be performing an arm swinging exercise or steps in synchrony with a metronome. The exercise menu consisted of 4 parts : arm swinging in a seated position, arm swinging in an upright position without stepping, arm swinging with stepping, and walking on the floor or taking a walk. The patients performed the arm swinging exercise while watching a video tape everyday for a period of 3.4 weeks. Of the 25 patients, 22 completed the exercise program. Following the program, these patients showed significant improvements in their walking times for a 20m walk (10 m, return, 10 m) (before/after=29.6/24.3 sec, p=0.002) and in the step length (before/after=43.7/50.1 cm, p<0.001). Frozen gait was a negative factor to complete the programs. Improvement of gait speed after the exercise was related with less frequency of cadence. Loss of arm swinging in PD may be associated with a disturbance in the internal rhythm formation process. Arm swinging exercises are one of the exercise methods that use rhythmic cues. This study suggests that a videotaped arm swinging-based home exercise therapy is effective in such patients.

Nutritional profiles in middle-aged trained and untrained women were compared both before and after menopause. Subjects were assigned to one of four groups : (1) pre-menopausal trained (Pre-T: n=14, aged 43±5 years, running distance 56±27 km/week, Vo₂max 49±4ml/ kg/min, mean±SD), (2) pre-menopausal untrained (Pre-UT: n=25, 42±5 years, 34±5 ml/kg/ min), (3) post-menopausal trained (Post-T: n=19, 53±3 years, 49±17 km/week, 42±6 ml/ kg/min), (4) post-menopausal untrained (Post-UT: n=26, 54±3 years, 31±3 ml/kg/min) . There were no significant differences in hematocrit (range 38.7 to 39.3%), hemoglobin (12.8 to 13.1 g/dl) and total protein (6.9 to 7.1 g/dl) among the four groups. Serum iron concentrations in the post-menopausal women (Post-T: 97±30μg/dl, Post-UT: 106±29μg/dl) were relatively higher than in the pre-menopausals (Pre-T: 85±35 pg/dl, Pre-UT: 78±33 pg/dl) . Mean total iron binding capacity in Post-UT (326 pg/dl) was lower than other groups (352 to 361 pg/dl) . Higher serum ferritin levels were observed in the post-menopausal women (Post-T : 35.8±27.5 ng/ml, Post-UT : 60.4±47.1 ng/ml) than the pre-menopausals (Pre-T: 18.3±13.1 ng/ml, Pre-UT: 16.6±10.7ng/ml) . Intake levels of the four groups with regard to the major nutrients were sufficient as compared with the recommended dietary allowance appropriate for age, sex and physical activity level. Intakes of calcium, iron and vitamins B₁, B₂ and niacin were higher in the trained groups than in the untrained. Regularly performed endurance exercise resulted in higher protein and iron intakes associated with higher energy intakes both before and after menopause. These results suggest that nutritional status of middle-aged women who regularly perform vigorous endurance running could be adequate for maintaining their health in a good state.

To identify the most frequently reported preferred terms （PTs） in the cases of rheumatoid arthritis （RA） patients treated with immunosuppressive biological drugs as suspected drugs, we analyzed the cases in the Japanese Adverse Drug Event Report （JADER） database. We found that pneumonia, interstitial lung disease, Pneumocystis jiroveci pneumonia （PCP), cellulitis, sepsis, and herpes zoster were the most frequently reported PTs. We obtained the reporting odds ratio （ROR） and the time to onset of these six PTs and compared them in the cases reported for each immunosuppressant as a suspected drug. We focused on RA treatment, including five tumor necrosis factor （TNF） antagonists （infliximab, etanercept, adalimumab, golimumab, and certolizumab pegol). For pneumonia, interstitial lung disease and sepsis, no specific correlation was observed for each immunosuppressant for RA. In the case of PCP, the highest ROR was observed in the patients treated with infliximab. The time to onset of PCP in the infliximab-treated patients （median, 0.19 yr） was significantly shorter than the onset time in the patients treated with tocilizumab, an interleukin-6 receptor blocker that is another type of drug for RA（0.32 yr, p<0.01, Mann-Whitney test). The onset time in the patients treated with golimumab （0.24 yr） was also significantly shorter than the onset time for tocilizumab（p<0.05), but the ROR was not as high. These results suggested a correlation between PCP and infliximab. In the cases of cellulitis and herpes zoster, a similar correlation was observed with tocilizumab and certolizumab pegol, respectively. We should consider these results when patients have a respiratory disorder or skin/subcutaneous tissue disorder.

Objective ： Infliximab is a chimeric monoclonal antibody against tumor necrosis factor (TNF) -α that is indicated in the treatment of chronic inflammatory diseases. Infliximab is administered by intravenous infusion and may be associated with infusion related reactions (IRRs). Recent study showed that the use of concomitant antihistamines associated with an increased incidence IRR, using an observational registry database in Canada. The aim of this study was to determine whether the use of concomitant antihistamines associated with an increase in the proportional reporting ratio (PRR) of IRR, using individual case safety reports (ICSRs) with infliximab as one of the suspected drugs, not only from Canada, but also from the United States of America (US), the United Kingdom (UK), and Japan.Design ： Case-control studyMethods ： We used VigiBase, the WHO's global safety report database, in this study. One-to-one propensity-matching analysis was performed in each country using IBM SPSS version 24 to evaluate outcomes. The primary endpoint was the assessment of concomitant medications associated with IRR in the cases treated with infliximab.Results ： There were 35,729, 19,095, 4,618, and 1,565 ICSRs in which some adverse events were reported with infliximab as one of the suspected drugs in Canada, the US, the UK, and Japan, respectively, after the exclusion of ICSRs with unknown patient age or unknown patient sex. IRRs were reported in 2,293, 1,427, 303, and 69 ICSRs, respectively. The use of concomitant antihistamines was significantly associated with an increased PRR of IRR in Canada (p<0.001). The uses of concomitant antihistamines were also significantly associated with an increased PRR of IRR in the US (p<0.001), the UK (p<0.001), and Japan (p＝0.007).Conclusion ： The uses of concomitant antihistamines were associated with an increased PRR of IRR with infliximab in the case-control study using ICSRs from Canada, the US, the UK, and Japan.

Fatigue is a common symptom of long COVID. Fatigue can majorly disrupt daily life and be challenging to treat. Herein, we describe the effect of saikokeishito, a Kampo medicine, on fatigue in patients with long COVID.Between October 2020 and March 2023, we prescribed saikokeishito to 22 patients with long COVID in the general medicine outpatient department of our hospital. Among them, seven patients (age: 15-58 years, two females) had fatigue, a previously confirmed diagnosis of COVID-19, and no concomitant use of other Kampo formulas. We compared their condition at the start of saikokeishito administration to that 3 months later. Five patients had a slight fever, and four had inflammatory findings on blood tests. Within 3 months, all patients had a 20% or greater reduction in fatigue on a visual analogue scale. Six patients had a 20% or greater increase in health-related QOL and were able to return to society. On the other hand, one patient required a transition to an alternative medication, and one patient's follow-up was prematurely discontinued. Fatigue after COVID-19 may be improved by saikokeishito, especially for the treatment of patients with slight fever or inflammatory findings.

Objectives  High gestational weight gain (GWG) is associated with perinatal risks to mother and child. Research shows that non-Japanese Asian women have higher GWG than Japanese women. However, no studies have compared GWG in these two populations using GWG recommendations in accordance with Japanese and Institute of Medicine (IOM) guidelines. The study aim was to compare GWG in non-Japanese Asian and Japanese pregnant women.Methods  This was a retrospective observational study. All participants were aged ≥20 years and gave birth between September 2019 and the end of October 2020 at one perinatal medical center in Japan. Medical record data were analyzed for 170 non-Japanese Asian and 316 Japanese pregnant women. We used t-tests and chi-square tests to examine differences in age, parity, smoking status, antenatal checkups, pre-pregnancy body mass index, and GWG. Logistic regression analysis was used to estimate odds ratios (95% confidence intervals) for above- and below-recommended GWG by non-Japanese Asian and Japanese status. We also analyzed differences in delivery type, abnormal blood loss, and birth size according to GWG.Results  After adjustment for confounding factors, the multivariable-adjusted OR and 95% CI for GWG above the Japanese guidelines recommendations was 1.86 (1.23-2.81) and that for GWG above IOM guidelines recommendations was 2.46 (1.45-4.16) for non-Japanese Asian women, as compared with Japanese women. Conversely, the multivariable-adjusted OR and 95% CI for GWG below Japanese guidelines recommendations was 1.55 (1.03-2.32) and that for GWG below IOM guidelines recommendations was 1.87 (1.26-2.76) for Japanese women, compared with non-Japanese Asian women. Conclusion  Because Japanese women tend to be below recommended GWG and non-Japanese Asian women tend to be above recommended GWG, midwives need to provide careful guidance to reduce perinatal risks.

Since students who would like to study Kampo medicine more have no opportunity to communicate each other in Northern Japanese Universities, we newly started joint study conferences held by medical students in 2013. The objectives of this paper are to report on these annually held student-based Kampo study conferences in the Hokkaido and Tohoku areas, and the ways each university studies Kampo medicine. In the conference, the students reported on their club activities. Then they studied the history of Kampo medicine and simulation of abdominal diagnosis, and performed group work on case reports together. The number of student participants in these conferences has tripled over 3 years from 18 to 58 (for a total of 111 participants). All members were satisfied with the content. And this reflects medical students' need for a wider perception of Kampo medicine, rather than a limited one gained in their university club activities. We hope this conference will play a major role in other nationwide student-based Kampo study conferences in the years to come.

We verified the educational outcomes and effects of the practice of Problem-based learning (PBL) on the theme of Kampo medicine and the continuous academic support. From 2013 to 2021, we conducted Kampo PBL for second-year medical students, and compared the results of Kampo exams in the fourth year between Kampo PBL participants and non-participants. Moreover, the learning obtained through subsequent academic activities was extracted from their free-form text. Kampo PBL was performed for a total of 26 groups. Participants who underwent Kampo PBL (n = 72) scored significantly higher than those who did not (n = 734) (p<0.05). In addition, academic support resulted in 5 academic presentations in an academic conference and 3 articles published in academic journals. The lessons learned included “concretization of understanding of Kampo medicine,” “valuable experience in academic activities,” and “promoting motivation and its impact on the future.” Kampo PBL improved knowledge about Kampo medicine, and academic activities cultivated the research mind.

Objective: In order to ensure the safety of nursing home residents, it is very important to implement appropriate assistance to ensure compliance with necessary medication. The purpose of this study is to identify issues and to plan solutions for medication assistance.Design: We conducted a workshop involving care workers (CWs), nurses and pharmacists together.Methods: Using the KJ method, participants extracted problems related to medication assistance and planned solutions in a mixed group of CWs, nurses and pharmacists. Questionnaire surveys were conducted for the participants before, immediately after, and 3 months after the workshop.Results: A number of important and urgent issues related to medication assistance were identified. There were differences in the recognition patterns of the importance and urgency of the issues among the three categories of participants. In addition, many possible solutions were proposed. Among these solutions, 25% had been implemented by at least two participants. More than 75 % of participants felt that their awareness of the value of cooperation in medication assistance had been improved by participating in the workshop.Conclusion: These results suggest that a workshop with a group of CWs, nurses and pharmacists in one place is a useful approach for extracting problems and planning effective solutions related to cooperation in medication assistance.
