Objective: Combination therapy with glecaprevir and pibrentasvir (G/P) has been shown to provide a sustained virologic response (SVR) rate of >97% in patients with chronic hepatitis C virus (HCV) infection in the first published real-world Japanese data. However, a recently published study showed that the treatment was often discontinued in patients ≥75 years old, resulting in low SVR in intention-to-treat (ITT) analysis. Thus, our aim was to evaluate real-world data for G/P therapy in patients ≥75 years of age, the population density of which is high in “rural” regions.Patients and Methods: We conducted a multicenter study to assess the efficacy and safety of G/P therapy for chronic HCV infection, in the North Kanto area in Japan.Results: Of the 308 patients enrolled, 294 (95.5%) completed the treatment according to the protocol. In ITT and per-protocol analyses, the overall SVR12 rate was 97.1% and 99.7%, respectively. The old-aged patients group consisted of 59 participants, 56 of whom (94.9%) completed the scheduled protocol. Although old-aged patients tended to have non-SVR factors such as liver cirrhosis, history of HCC, and prior DAA therapies, the SVR12 rates in old-aged patients were 98.3% and 100% in the ITT and PP analyses, respectively. Of 308 patients enrolled, adverse events were observed in 74 patients (24.0%), with grade ≥3 events in 8 patients (2.6%). There was no significant difference in any grade and grade ≥3 adverse events between the old-aged group and the rest of the study participants. Only one patient discontinued the treatment because of adverse events.Conclusion: G/P therapy is effective and safe for old-aged patients.

The first edition of the guidelines for the use of ultrasound contrast agents was published in 2004, dealing with liver applications. The second edition of the guidelines in 2008 reflected changes in the available contrast agents and updated the guidelines for the liver, as well as implementing some nonliver applications. The third edition of the contrast-enhanced ultrasound (CEUS) guidelines was the joint World Federation for Ultrasound in Medicine and Biology-European Federation of Societies for Ultrasound in Medicine and Biology (WFUMB-EFSUMB) venture in conjunction with other regional US societies such as Asian Federation of Societies for Ultrasound in Medicine and Biology, resulting in a simultaneous duplicate on liver CEUS in the official journals of both WFUMB and EFSUMB in 2013. However, no guidelines were described mainly for Sonazoid due to limited clinical experience only in Japan and Korea. The new proposed consensus statements and recommendations provide general advice on the use of Sonazoid and are intended to create standard protocols for the use and administration of Sonazoid in hepatic and pancreatobiliary applications in Asian patients and to improve patient management.

BACKGROUND: Like most women, female nurses in the workforce experience life events such as marriage, childbirth, and child-rearing, and carry out numerous personal roles. This may result in an increase in various demands for nurses, and coping with these roles may promote work engagement. However, few studies have focused on work engagement or spillover effects, including those in the family domain, in female nurses with multiple roles. In the present study, we aimed to examine work engagement in female nurses and investigate its relationship with factors such as the presence or absence of multiple personal roles. METHODS: The subjects of this study were 1225 female nurses working at three general hospitals, each with at least 200 hospital beds in Fukuoka Prefecture, Japan. The cross-sectional design of the study used anonymous self-administered questionnaires. Responses were received from 650 nurses (response rate 53.1%), of which 612 were valid (valid response rate 50.0%). Multiple regression analysis was performed on the 612 responses regarding associations between work engagement and the presence or absence of multiple roles (role as a wife or mother), spillover effects, coping characteristics, job demands, and job resources. RESULTS: In general, the work engagement of female nurses was low, as is the case with other female workers in Japan, but work engagement was higher among female nurses with multiple roles than among those without. The regression analysis showed that factors associated with better work engagement in female nurses were family-to-work positive spillover, job resources, coping strategies including "changing a point of view," "active solution for problems," "avoidance and suppression," and the presence of multiple roles. CONCLUSIONS The results indicate that in addition to resources in the work domain, a family-to-work positive spillover effect, which is a variable in the non-work domain, may also promote energetic work among female nurses. Therefore, it is necessary for nurses to receive support at work and use effective coping strategies.

A 67-year-old man with ascending aortic aneurysm was referred to our hospital. Transthoracic echocardiography showed severe aortic regurgitation with annuloaortic ectasia and transesophageal echocardiography revealed a quadricuspid aortic valve. This patient underwent aortic root replacement with a valve sparing technique. Under deep hypothermic circulatory arrest with retrograde cerebral perfusion, replacement of the ascending aorta was successfully performed. The postoperative course was uneventful. This patient is doing well 6 months after surgery without recurrence of aortic regurgitation.

We measured oxidative stress and antioxidative stress in clinical cases of cardiac and aortic surgery, especially in extracorporeal circulation cases. From June to October 2007, 18 cases who underwent cardiac and aortic surgery with extracorporeal circulation (ECC group) and 8 cases with an infra-renal abdominal aortic aneurysm (AAA group) were studied. We measured reactive oxygen metabolites (d-ROM) in oxidative stress for the operative time, after the operation endpoint, and at one day postoperatively, one, two, and three weeks postoperatively, and one, two, three, and four months postoperatively. Regarding d-ROM, the level in the ECC group was significantly higher than that in the AAA group (p<0.0001). Peak values were observed 3 weeks postoperatively in the ECC group and 2 weeks postoperatively in the AAA group. Although the oxidative stress increased in both groups, the peak value in the ECC group was more marked than that in the AAA group. We concluded that oxidative stress under surgical stress in cardiovascular surgery with extracorporeal circulation was higher than that under surgical stress in cardiovascular surgery for infra-renal abdominal aortic aneurysms.

We report 3 cases of ascending aorta-abdominal aorta bypass for atypical coarctation with Takayasu's aortitis. We performed an extra-anatomical bypass from the ascending aorta to the terminal abdominal aorta. The graft was arranged to pass through the diaphragm from the pericardium, behind the left lobe of the liver and the stomach, to the front side of the pancreas to the terminal abdominal aorta. Although the graft was exposed in the abdominal cavity in part behind the stomach, it was completely covered with the great omentum thus avoiding direct contact between the graft the abdominal organs. Decrease in the pressure gradient between the ascending aorta and the abdominal aorta was achieved using a large prosthetic graft 14-16 mm in diameter. There are several advantages with this technique. (1) Positional change during surgery can be avoided. (2) Anastomosis can be performed in non-diseased vessels. (3) This bypass graft can be branched off to visceral arteries if necessary. Reduction of the after load on the left ventricle and long-term graft patency by using a large diameter prosthetic graft were anticipated. The postoperative courses of all cases were satisfactory. Case 1 died of another disease 11 years and 11 months postoperatively, but the graft to was still patent.
