We report a case of surgical repair of acquired left ventricular-right atrial communication resulting from infective endocarditis. A 70-year-old man with aortic regurgitation due to infective endocarditis was referred to our hospital because of congestive heart failure. Preoperative transthoracic echocardiography showed severe aortic regurgitation and left ventricular-right atrial shunt flow. He underwent surgery following intensive antibiotic therapy. The fistula was located at the atrioventricular membranous septum. The communication site from the left ventricular view it was below the commissure between the left and the non-coronary cusps, and from the right atrial view it was above the tricuspid annulus of the septal leaflet. The fistula was closed with autologous pericardial patch from the aortotomy and a mattress suture from the right atriotomy. Aortic valve replacement was performed simultaneously. The postoperative course was uneventful. He was in sinus rhythm all the time. It is important to discuss surgical procedure preoperatively with precise echocardiographic examination.

A Valsalva aneurysm filled with thrombi can be difficult to diagnose, because it mimics a cardiac tumor. Both cardiac magnetic resonance imaging (MRI) and transesophageal echocardiogram (TEE) were performed on a patient who showed a low-echoic mass located between the atrial septum and the non-coronary sinus. Based on MRI findings allowing tissue characterization and the accurate location of the mass and the TEE findings of an irregular surface of the mass and a partial defect in the edge of the non-coronary sinus, we diagnosed the mass as a thrombosed Valsalva aneurysm that had perforated the inter-atrial septum. The operative findings coincided with the preoperative diagnosis. Both MRI and TEE are useful for diagnosing this condition.

Background: The demand for palliative care in Japan has risen over recent years, and training of palliative care physicians is an important problem. However, little is known about unmet needs for education and training systems as well as career development among young physicians who wish to specialize in palliative care. Purpose: To explore unmet needs among palliative care physicians in training. Method: We held group discussions in a forum for physicians of postgraduate year≦15, and analyzed their opinion on topics such as "what are unmet needs?" using theme analysis. Results: Forty physicians participated. Theme analysis revealed the following unmet needs among young physicians; "securing of manpower", "securing of quality of training programs/education", "improvement of network", "removal of many barriers to keeping on a palliative care physician", and "establishment of career models for a specialist". Conclusions: We should discuss solutions for the unmet needs to secure more palliative care physicians.

Objective: This study aimed to investigate the accuracy and precision of continuous, non-invasive blood pressure obtained using the ClearSight system by comparing it with invasive arterial blood pressure, and to assess the hemodynamic changes using invasive methods and the ClearSight system in patients undergoing cesarean section. Methods: Arterial pressure was measured invasively with an intra-arterial catheter and non-invasively using the ClearSight system during cesarean section in patients with placenta previa or placenta accreta. Blood pressure measurements obtained using these two means were then compared. Results: Total 1,277 blood pressure measurement pairs were collected from 21 patients. Under Bland-Altman analysis, the ClearSight system demonstrated an acceptable accuracy with a bias and standard deviation of 8.8±13.4 mmHg for systolic blood pressure, -6.3±7.1 mmHg for diastolic blood pressure, and -2.7±8.0 mmHg for median blood pressure. Cardiac index levels were significantly elevated during fetal delivery and 5 minutes after placental removal, and systemic vascular resistance index levels were significantly decreased during fetal delivery and 40 minutes after placental removal. Conclusion In patients undergoing cesarean section, the ClearSight system showed excellent accuracy and precision compared to that of the currently used invasive monitoring system.

Behçet’s disease (BD) is a multisystem inflammatory disease of unknown origin. Rarely, BD occurs together with myelodysplastic syndrome (MDS). Interestingly, it is speculated that these are not simple coexistence but that the etiology of intestinal BD is at least partly derived from MDS itself. Furthermore, there is a relationship between MDS in patients with intestinal BD and trisomy 8. Immunosuppressive agents alone are insufficient to control MDS-associated BD, and many of these patients die of infection or hemorrhage. Surgery is considered for intestinal BD patients who are unresponsive to medical treatment or those with bowel complications such as perforation or persistent bleeding. We report a case of intestinal BD associated with MDS and trisomy 8. The patient was unresponsive to oral steroids and immunosuppressive treatment; the patient improved by surgical repair of a bowel perforation. Five years after the surgery, the patient is free of recurrence and not on medication. Our experience suggests that surgery may provide an effective therapeutic option for the treatment of MDS-related BD.

Drug dispensing is a statutory and designated duty of a pharmacist. We aimed to examine the changes in the nature of drug dispensing using a text mining method. Our corpus consisted of text documents from “Chozai Shishin”, the most standard manual for dispensing drugs in Japan, Editions 1 to 13 (Japan Pharmaceutical Association), and we used the KH Coder software for text mining. We constructed networks showing the association between frequent word co-occurrence and edition number, and co-occurrence relations for frequent words in each edition. We found that “patient” superseded “dispensing” as a frequent term over time. “Dispensing” was another frequent term with a highly centralized node in each edition. Accordingly, we targeted the term “dispensing” for network analysis to depict its co-occurrence relations. We found that the range of related words for “dispensing” broadened from “preparation” and “compounding” to include “patient adherence instructions”, “assessment”, “medical treatment”, and “information provision”. Accordingly, we concluded that the content of “dispensing”, which is a pharmacist’s duty, has expanded from the duties of “dispensing drugs” to include “responding to patients” within the definition of “dispensing”, and we were able to present this finding as objective data by using the mechanical method known as text mining.

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.

As a serine hydrolase, monoacylglycerol lipase (MAGL) is principally responsible for the metabolism of 2-arachidonoylglycerol (2-AG) in the central nervous system (CNS), leading to the formation of arachidonic acid (AA). Dysfunction of MAGL has been associated with multiple CNS disorders and symptoms, including neuroinflammation, cognitive impairment, epileptogenesis, nociception and neurodegenerative diseases. Inhibition of MAGL provides a promising therapeutic direction for the treatment of these conditions, and a MAGL positron emission tomography (PET) probe would greatly facilitate preclinical and clinical development of MAGL inhibitors. Herein, we design and synthesize a small library of fluoropyridyl-containing MAGL inhibitor candidates. Pharmacological evaluation of these candidates by activity-based protein profiling identified
