Objective: To implement early rehabilitation interventions by physical therapists is recommended. However, the effectiveness of early rehabilitation for severe coronavirus disease 2019 (COVID-19) patients in the prevention of post-intensive care syndrome (PICS) is unclear. We analyzed a multicenter prospective observational study (Post-Intensive Care outcomeS in patients with COronaVIrus Disease 2019) to examine the association between early rehabilitation interventions and PICS physical impairment. Methods: An analysis was performed on COVID-19 patients who were admitted to intensive care units (ICUs) between March 2020 and March 2021, and required mechanical ventilation. The primary outcome was the incidence of PICS physical impairment (Barthel Index≤90) after one year. Multivariate logistic regression analysis was used to estimate the association between early rehabilitation interventions and PICS physical impairment by adjusting ICU mobility scale (IMS) during seven-day following ICU admission, and clinically relevant risk factors. Results: The analysis included 259 patients, 54 of whom developed PICS physical impairment one year later. In 81 patients, physical therapists intervened within seven days of ICU admission. There was no significant difference in mean IMS by day seven of admission between the early and non-early rehabilitation patients (0.70 and 0.61, respectively). Multivariate logistic regression analysis showed that early rehabilitation interventions were significantly associated with a low incidence of PICS physical impairment (odds ratio, 0.294; 95% confidence interval, 0.123–0.706; p=0.006). Conclusion Early rehabilitation interventions by physical therapists were an independent factor associated with the decreased development of PICS physical impairment at one year, even though early rehabilitation had no significant effect on IMS.

The U-40 generation of cardiovascular surgeons is receiving training as cardiovascular surgeons, including daily surgeries, ward responsibilities and other important tasks, young surgeons are on their way to becoming skilled cardiovascular specialists. However, it is said that it takes a long time to become a full-fledged surgeon, and in particular, the way to becoming a full-fledged cardiovascular surgeon varies greatly among individuals and is not standardized. Therefore, the U-40 generation is always concerned and worried about their future career development. At the 54th Annual Meeting of the Japanese Society for Cardiovascular Surgery, we will discuss what the U-40 generation needs to become full-fledged surgeons, what they are worried about, and how their seniors who are actually active as independent cardiovascular surgeons think and what their career paths have been like. I had an opportunity to reflect on the gap between the two. This time, we conducted a questionnaire survey to visualize the conditions and future prospects for becoming an independent surgeon as considered by the U-40 generation.

A 25-question “Nationwide Kampo Web Test” was conducted to evaluate the basic knowledge and diagnostic ability of Kampo among medical professionals nationwide. We analyzed the scores of all 608 examinees (241 doctors, 257 pharmacists, 77 others, 12 acupuncturists, 10 nurses, and 11 dentists) and evaluated the test quality. The performance of all examinees was 67.7 ± 16.9 points (mean score ± standard deviation). Among the doctors, the mean score of Kampo medicine specialists (83.8 ± 8.7 points) was significantly higher than that of non-specialists (65.3 ± 16.3 points) (p<0.0001). The performance of doctors who prescribed 20 or more Kampo medicines (78.4 ± 11.5 points) was significantly higher than that of other doctors (p<0.0001). Among the 25 questions, the difficulty levels of 13, 8, and 4 were easy, moderate, and hard (correct answer rates: 70% or more, 40-70%, and less than 40%), respectively. The ability of 13 questions (52%) to distinguish between good and poor performers was extremely high (discrimination index of 0.5 or higher). Collectively, these results supported the good performance of our test, suggesting that it is a highly practical learning achievement evaluation system that could utilize information and communication technology and is expected to be used in future lifelong learning in the field of Kampo medicine.

Todo Yoshimasu was one of the Kampo doctors of the Koho school in the Edo period, and created the basic structure of the modern traditional Japanese Kampo medicine. His achievements are still recognized today. His oldest son, Nangai Yoshimasu, is also credited with inheriting and developing the medical techniques established by his father. Todo’s descendants continued to be involved in the medical profession. In this paper, we first report that the building of the Yoshimasu clinic still exists in Tsuwara, Kurayoshi City, Tottori Prefecture, where Shiho Yoshimasu, the fifth-generation descendant of Todo, and his son Ryozo practiced medicine. We also found the tombstones there for Tetsutaro (Shiho), Yutaro, Ryozo, Tamenori, and Teruo of the Yoshimasu family. In conclusion, one of the origins of the Yoshimasu’s, a well-known family of doctors in Japan, is in Tottori. Therefore, Tsuwara, Kurayoshi City, Tottori Prefecture is an important place to describe Todo Yoshimasu. Here, we revealed the Yoshimasu family in Tottori based on new materials.

As part of U-40 activities, chapters have traditionally held sessions of lectures and hands-on as the Basic Lecture Course (BLC) to improve the basic skills and knowledge of young cardiovascular surgeons. Because of the COVID-19 epidemic, we have shifted our activities from onsite to online. This column focuses on “management of postoperative delirium and pain” in the lecture of “Postoperative Management in Cardiovascular Surgery” given by the Chubu Chapter in 2020. We summarize the lecture and report the results of a questionnaire survey of the U-40 members.

Objective: Maternal embryonic leucine zipper kinase (MELK) is receiving an attention as a therapeutic target in various types of cancers. In this study, we aimed to evaluate the prognostic significance of MELK expression in ovarian cancer using clinical samples, and assessed the efficacy of a small molecule MELK inhibitor, OTS167, using patient-derived ovarian cancer cells as well as cell lines. Methods: Expression levels of MELK in 11 ovarian cancer cell lines were confirmed by western blotting. Inhibitory concentration of OTS167 was determined by colorimetric assay.MELK messenger RNA (mRNA) expression was evaluated in 228 ovarian cancer patients by quantitative polymerase chain reaction. Growth inhibition of OTS167 was also evaluated using freshly-isolated primary ovarian cancer cells including spheroid formation condition. Results: MELK mRNA expression was significantly higher in ovarian cancer than in normal ovaries (p<0.001), and high MELK mRNA expression was observed in patients with advanced stage, positive ascites cytology and residual tumor size. Patients with high MELK mRNA expression showed shorter progression-free survival (p=0.001). Expression of MELK was also confirmed in 10 of 11 ovarian cancer cell lines tested, and the half maximal inhibitory concentration of MELK inhibitor, OTS167, ranged from 9.3 to 60 nM. Additionally, OTS167 showed significant growth inhibitory effect against patient-derived ovarian cancer cells, regardless of their tumor locations, histologic subtypes and stages. Conclusions We demonstrated MELK as both a prognostic marker and a therapeutic target for ovarian cancer using clinical ovarian cancer samples. MELK inhibition by OTS167 may be an effective approach to treat ovarian cancer patients.

BACKGROUND: The Rugby World Cup (RWC) is one of the biggest international mega sports events in the world. This study was conducted to identify and evaluate the volume, nature, and severity of spectator medical care in the stadiums of 12 venues across Japan during RWC 2019. METHOD: This was a retrospective review of medical records from spectator medical rooms of 45 official matches of RWC 2019 between September 20 and November 2, 2019. All patients in the stadium who visited the spectator medical room and were transferred to a hospital were included. The wet bulb globe temperature (WBGT) value at the kick-off time of each match, the number of visits to the spectator medical room, and the number of transfers to a hospital were reviewed and analyzed. The patient presentation rate (PPR) was calculated per 10,000 attendees. Severity categories were defined as mild or severe. Mild cases were considered non-life threatening requiring minimal medical intervention, and severe cases required transport to a hospital. RESULT: The total number of visits to the spectator medical room was 449 with a PPR of 2.63. Most cases (91.5%) were mild in severity. The PPR was significantly higher for the matches held with a WBGT over 25 °C than for the matches under 21 °C (PPR 4.27 vs 2.04, p = 0.04). Thirty-eight cases were transferred to a hospital by ambulance; the PPR was 0.22. The most common reasons for transfer to the hospital were heat illness and fracture/dislocation, at a rate of 15.8% each. The incidence rate of cardiopulmonary arrest per 10,000 attendees was 0.0059 during RWC 2019. CONCLUSION Preparation and provision of appropriate medical service for spectators is a key factor for mass-gathering events. During RWC 2019, the majority (91.5%) of patients who sought medical attention did so for minor complaints, which were easily assessed and managed. On the other hand, a higher WBGT situation contributes significantly to an increased PPR (< 21 versus > 25, 2.04 versus 4.27, p = 0.04). Careful medical preparation, management, and development of public education programs for higher WBGT situations will be required in the future for similar international mega sports events.

BACKGROUND: Studies on the adverse effects of Asian dust (AD) on respiratory function in children are scarce. The objective of this study was to examine the association between AD and respiratory function by measuring peak expiratory flow rates (PEFRs) in asthmatic children. METHODS: The study was carried out from March to May from 2014 through 2016. One hundred ten children with bronchial asthma were recruited from four hospitals in the Goto Islands and south Nagasaki area in Nagasaki prefecture. The parents were asked to record their children's PEFRs every morning/evening and clinical symptoms in an asthma diary. AD was assessed from light detection and ranging data, and a linear mixed-effects model was used to estimate the effects of AD on daily PEFR. Time-stratified case-crossover analyses were performed to examine the association between AD and asthma attacks defined by reduction levels in PEFR. RESULTS: AD was detected on 11 days in the Goto Islands, and on 23 days in the south Nagasaki area. After adjusting for age, sex, temperature, and daily oxidants, we found a consistent association between AD and a 1.1% to 1.7% decrease in PEFR in the mornings and a 0.7% to 1.3% decrease in the evenings at a lag of 0 to 5 days. AD was not associated with the number of asthma attacks, respiratory symptoms, or other symptoms at any lag days examined. CONCLUSIONS Exposure to AD was associated with reduced PEFR, although the effects were not large enough to induce clinically apparent symptoms, in clinically well-controlled asthmatic children.
