The patient was an 82-year-old woman. For dysphagia scrutiny, upper gastrointestinal endoscopy and biopsy of a submucosal tumor of the midthoracic esophagus were performed. The patient was urgently admitted to the Department of Gastroenterology for examination and treatment. After admission, enhanced CT showed a descending thoracic aortic aneurysm (DTA) pressing on the esophagus. On the third day of hospitalization, the patient suffered massive hematemesis and went into shock, and emergency thoracic endovascular aortic repair (TEVAR) was performed with resuscitation based on the diagnosis of esophageal perforation of the DTA. The patient was weaned from the ventilator by tracheotomy without cerebrospinal complications and left the intensive care unit on the seventh postoperative day. One month after surgery, a CT scan showed that the DTA had almost disappeared and that the esophageal compression had been released. The patient was managed with antibacterial therapy and nutritional support other than oral intake and was discharged home 7 months after surgery without stent graft infection or mediastinitis. The usefulness of TEVAR for ruptured descending thoracic aortic aneurysms has been reported in many cases. However, in patients with an aortoesophageal fistula (AEF), esophagectomy is required after TEVAR to control infection, and the mortality rate of this disease is high. We report a case in which infection were controlled by antibacterial therapy and nutritional management other than oral intake after TEVAR and the patient survived.

Some simulation-based education tools have been introduced in Kampo medicine. However, there are only a few brief simulation tools to learn qi-blood-fluid (QBF) patterns of traditional Chinese medicine (TCM). In this study, we developed a self-diagnostic questionnaire that allows students learn TCM interviews and QBF patterns by answering the questionnaire and evaluated its reliability and validity. We extracted questionnaire items to classify six QBF patterns (qi deficiency, blood deficiency, yin deficiency, qi stagnation, blood stasis, and phlegm-fluid retention) based on some textbooks of TCM and Kampo medicine. Then we developed an initial questionnaire comprising 35 items. Fifth year medical students at Tohoku University School of Medicine answered the questionnaire of small group teaching during 2017-2020. We evaluated the accuracy of the questionnaire if compared with the diagnosis of academic supervisors. To improve the accuracy, we adjusted the questionnaire’s thresholds and created a predictive model of the patterns using logistic regression analysis. The questionnaire’s sensitivity improved by adjusting the thresholds. Logistic regression analysis resulted in a predictive model that could determine QBF patterns with the same level of accuracy as the original for 20 items overall. The results suggest that the use of a simple questionnaire with ensured accuracy may contribute to better pre-graduate education by making it easier for students to understand their own Kampo medicine patterns.

Objective:
To examine the association between the mobilization level during intensive care unit (ICU) admission and independence in activity of daily living (ADL), defined as Barthel Index (BI)≥70.
Methods:
This was a post-hoc analysis of the EMPICS study involving nine hospitals. Consecutive patients who spend >48 hours in the ICU were eligible for inclusion. Mobilization was performed at each hospital according to the shared protocol and the highest ICU mobility score (IMS) during the ICU stay, baseline characteristics, and BI at hospital discharge. Multiple logistic regression analysis, adjusted for baseline characteristics, was used to deter-mine the association between the highest IMS (using the receiver operating characteristic [ROC]) and ADL.
Results:
Of the 203 patients, 143 were assigned to the ADL independence group and 60 to the ADL dependence group. The highest IMS score was significantly higher in the ADL independence group than in the dependence group and was a predictor of ADL independence at hospital discharge (odds ratio, 1.22; 95% confidence interval, 1.07–1.38; adjusted p=0.002). The ROC cutoff value for the highest IMS was 6 (specificity, 0.67; sensitivity, 0.70; area under the curve, 0.69).
Conclusion
These results indicate that, in patients who were in the ICU for more than 48 hours, that patients with good function in the ICU also exhibit good function upon discharge. However, prospective, multicenter trials are needed to confirm this conclusion.

Objective:
To investigate the effect on early mobilization in patients undergoing extra-corporeal membrane oxygenation (ECMO) and acute blood purification therapy in the intensive care unit (ICU).
Methods:
We conducted this multicenter retrospective cohort study by collecting data from six ICUs in Japan. Consecutive patients who were admitted to the ICU, aged ≥18 years, and received mechanical ventilation for >48 hours were eligible. The analyzed were divided into two groups: ECMO/blood purification or control group. Clinical outcomes; time to first mobilization, number of total ICU rehabilitations, mean and highest ICU mobility scale (IMS); and daily barrier changes were also investigated.
Results:
A total of 204 patients were included in the analysis, 43 in the ECMO/blood purification group and 161 in the control group. In comparison of clinical outcome, the ECMO/blood purification group had a significantly longer time to first mobilization: ECMO/blood purification group 6 vs. control group 4 (p=0.003), higher number of total ICU rehabilitations: 6 vs. 5 (p=0.042), lower mean: 0 vs. 1 (p=0.043) and highest IMS: 2 vs. 3 (p=0.039) during ICU stay. Circulatory factor were most frequently described as barriers to early mobilization on days 1 (51%), 2 (47%), and 3 (26%). On days 4 to 7, the most frequently described barrier was consciousness factors (21%, 16%, 19%, and 21%, respectively)
Conclusion
The results of this study comparing the ECMO/blood purification group and the untreated group in the ICU showed that the ECMO/blood purification group had significantly longer days to mobilization and significantly lower mean and highest IMS.

Objectives: A refill-prescription system startedin April, 2022 in Japan. Refill-prescriptions can be usedrepeatedly, but pharmacists are required to check patients' medication and determine whether refills are appropriate. This study aimed to clarify the actual status of community pharmacies' treatment of prescription refills and pharmacists’ concerns about them.Design: Questionnaire survey.Methods: A self-administered questionnaire survey was conducted for pharmacists at community pharmacies from June to July, 2022, shortly after the refill-prescription system was launched, focusing on handling of prescription refills in community pharmacies, and concerns and challenges about refill-prescriptions.Results: Responses were obtainedfrom 377 pharmacists in 34 prefectures throughout Japan. Among them, 30.8% had received refill-prescriptions. Many pharmacists checked medical histories, changes in patients' symptoms, and medication and medical examination status when determining the appropriateness of refills, but few reviewed past laboratory values or laboratory values measuredby patients themselves at the time of their pharmacy visit. Moreover, 34.8% of the pharmacies had internal rules for dealing with refills, and 39.8% had equipment to measure laboratory values. Many pharmacists were concerned about how to share patients’ information with other pharmacies. Challenges that were identified included “Determining whether the refill is appropriate for the patient” and “Establishment of a pharmacy system to receive refill-prescriptions”.Conclusion: This study clarified the actual status of community pharmacies handling of prescription refills, and pharmacists' concerns or challenges about them. Potential improvements include increasing the number of devices that can measure laboratory values at pharmacies, improving home-use measuring devices, creating guidelines to determine the appropriateness of prescription refills and improving pharmacists' skills.

A 70-years-old woman who had been on hemodialysis for 8 years was referred to our institution to undergo mitral surgery for mitral valve stenosis. Intraoperative investigations confirmed severe calcification of the posterior mitral leaflet and all-around mitral annulus. We excised the mitral leaflet using the Ultrasonic Surgical System and preserved the calcified annulus to prevent a fatal complication such as left ventricular rupture. We passed 2-0 polyester mattress sutures through the calcified annulus from the left ventricle to the left atrium, and mitral valve replacement was performed using a reversed 19 mm On-X mechanical heart valve for the aortic valve. The postoperative course was uneventful. Mitral annular calcification is a factor of fatal complications such as left ventricle rupture and coronary artery injury. We succeeded in preserving the calcified annulus and using a small diameter mechanical heart valve.

We report a successful case of fulminant myocarditis treated with central ECMO with a transapical left ventricular vent (TLVV). A 33-year-old man was diagnosed with fulminant myocarditis with acute biventricular failure. Using a cardio-pulmonary bypass, we introduced central ECMO with ascending aortic perfusion, right atrial venous drainage and TLVV. After ancillary circulation, his cardiac function gradually improved. The endotracheal tube was removed 5 days after the surgery (POD 5), and he was weaned from ECMO on POD 7 and discharged on POD 38. Although there are many cases in which peripheral veno-arterial ECMO (VA-ECMO) is used for fulminant myocarditis, there is a drawback to VA-ECMO : left ventricle (LV) unloading may be incomplete. Insufficient LV unloading may cause pulmonary congestion or disadvantage in myocardial recovery. TLVV can be used as a solution to unload the left ventricle. Central ECMO with TLVV should be useful therapy for fulminant myocarditis.

A 76-year-old man with a complaint of dyspnea was diagnosed with acute severe mitral regurgitation due to ruptured chordae tendineae. For improvement of pulmonary congestion, we introduced IMPELLA 5.0® and extra-corporeal membrane oxygenation before valve surgery. After two-days' IMPELLA 5.0® support, mitral valve replacement surgery with a bioprosthetic valve was performed and IMPELLA 5.0® was withdrawn. We report a successful case of a bridge to surgery using IMPELLA 5.0® with mitral valve regurgitation accompanied by acute left heart failure with severe respiratory failure.

The prognostic significance of initial prostate-specific antigen (PSA) level for metastatic prostate cancer remains uncertain. We investigated the differences in prognosis and response to hormonal therapies of metastatic prostate cancer patients according to initial PSA levels. We analyzed 184 patients diagnosed with metastatic prostate cancer and divided them into three PSA level groups as follows: low (<100 ng ml-1), intermediate (100-999 ng ml-1), and high (≥1000 ng ml-1). All patients received androgen deprivation therapy (ADT) immediately. We investigated PSA progression-free survival (PFS) for first-line ADT and overall survival (OS) within each of the three groups. Furthermore, we analyzed response to antiandrogen withdrawal (AW) and alternative antiandrogen (AA) therapies after development of castration-resistant prostate cancer (CRPC). No significant differences in OS were observed among the three groups (P = 0.654). Patients with high PSA levels had significantly short PFS for first-line ADT (P = 0.037). Conversely, patients in the high PSA level group had significantly longer PFS when treated with AW than those in the low PSA level group (P = 0.047). Furthermore, patients with high PSA levels had significantly longer PFS when provided with AA therapy (P = 0.049). PSA responders to AW and AA therapies had significantly longer survival after CRPC development than nonresponders (P = 0.011 and P < 0.001, respectively). Thus, extremely high PSA level predicted favorable response to vintage sequential ADT and AW. The current data suggest a novel aspect of extremely high PSA value as a favorable prognostic marker after development of CRPC.

We report a case of endovascular surgery in a patient of common iliac artery aneurysm with arteriovenous (A-V) fistula. A 60-year-old woman was admitted because of dyspnea. She had a clinical history of lumbar disk surgery at age of 40. On physical examination, we detected a pulsatile mass and pansystolic murmurs in her left lower abdomen. A chest X-ray film demonstrated severe cardiomegaly with 70% of cardiothoracic ratio. Contrast-enhanced CT revealed left common artery aneurysm with A-V fistula between the left common iliac artery and the left common iliac vein. Three-dimensional CT showed hyper-vascularity in the region from the pelvic vein to IVC. We considered that she had high risk of intraoperative massive bleeding for open abdominal surgery. We conducted endovascular repair for this iliac artery aneurysm with A-V fistula by the GORE EXCLUDER C3® stent graft system. Postoperative contrast-enhanced CT showed complete exclusion of both left common iliac artery aneurysm and A-V fistula. After surgery, her symptoms improved significantly.
