Since 2005, one of our clinical technologists has been involved in providing assisted reproductive technology (ART) services ranging from egg retrieval to embryo transfer, which were previously performed only by doctors at our hospital. In 2011, the clinical technologist was certified as a clinical embryologist by the Japanese Society of Clinical Embryologists. Around 2020, insurance coverage for ART related to infertility treatment began to be considered. Consequently, the training and development of ART-supporting clinical technologists became an urgent issue. In response, we developed a training program for ART-supporting clinical technologists that covers egg retrieval assistance, fertilization, culture, embryo freezing/thawing, and embryo transfer. By the end of fiscal year 2022, we had successfully trained two new ARTsupporting clinical technologists, bringing the total to three.

Introduction: To examine the relationship between empathy and burnout among a multi-professional population at a remote base hospital. Methods: This study was conducted as a single-center cross-sectional study from November 1 to 30, 2024. The subjects were all 263 staff members working at a remote base hospital. Empathy was assessed using the Japanese version of the Interpersonal Reactivity Index (IRI), and burnout was assessed using the Japanese version of the Burnout Assessment Index (BAT-J). Correlation analysis and analysis of variance were used for data analysis. Results: Of the 136 respondents (response rate 51.7%), 123 were included in the analysis. The participants had an average of 18.6 years of professional experience (± 11.0 years). Mean IRI and BAT-J scores were 87.3 (± 11.2) and 79.1 (± 17.7), respectively. A weak positive correlation was observed between IRI and BAT-J scores. Among professions, nurses showed significantly higher BAT-J scores than therapists and technicians. No significant differences were observed in IRI. Conclusion: We found no significant difference in empathy among professions. However, our findings suggest that nurses were at higher risk of burnout than therapists.

We evaluated the efficacy of sternal coaptation pins used to improve the fixation of the transected sternum after coronary artery bypass grafting (CABG) with the internal thoracic artery (ITA). The subjects were 37 patients who underwent scheduled single CABG with ITA in our department and they were classified into two groups, i. e., Group A, without sternal pins (18 patients), and Group B, with sternal pins (19 patients). The efficacy was assessed by the following measurements : drain bleeding volume up to 12 and 24 h after ICU admission, the time until the removal of drain, surgical site infection (SSI) and the maximum split level between the sternal body and manubrium after surgery. Drain bleeding volume up to 12 and 24 h after ICU tended to be less in Group B. The time until the removal of drain was significantly shorter in Group B. SSI was 17% in Group A but 0% in Group B. The use of sternal coaptation pins reduced misalignment of the coapted sternum, and we belive that the use of sternal coaptation pins contributed to the early removal of drain, and SSI reduction.

We evaluated long-term survival and morbidity of 191 patients (161 non-ruptured and 30 ruptured) undergoing abdominal aortic aneurysm repair between 1980 and 1997. Thirty-day mortality rates of non-ruptured and ruptured aneurysms were 1.2% and 36.6%, respectively. Hospital death occurred in 3.1% of patients with non-ruptured aneurysms and 53.3% of those with ruptured aneurysms. Cumulative survival rates after successful AAA repair at 5 and 10 years were 76.3% and 42.3%, respectively. These were lower than survival rates in the age- and gender-matched general population. The most frequent cause of late death was cardiac problems (28.8%) including myocardial infarction. Other causes included stroke (19.2%), malignant neoplasm (17.3%), and ruptured recurrent aneurysms at or above the proximal anastomosis (9.6%) including aorto-enteric fistulas. Regarding late vascular complications, recurrent aneurysms at or above the proximal anastomosis were found in 10% of patients, including 3.5% of true aneurysms, 4.7% of anastomotic aneurysms, and 1.8% of aorto-enteric fistulas. Thoracic aortic aneurysms were found in 3.7% and aortic dissection in 4.2%. Cumulative graft patency rates at 10 and 15 years were 97.4% and 90.9%, respectively. Suppressive treatment for arteriosclerosis and continuous careful follow-up with an aggressive diagnostic approach may reduce morbidity and mortality from recurrent aneurysms or coronary artery disease, thereby improving late survival after AAA surgery.

A 71-year-old man was referred to the University Hospital because of left lumbago and a pulsating mass in his umbilical region. An inflammatory abdominal aortic aneurysm 5cm in diameter and left hydronephrosis were identified by enhanced computed tomography (CT). One month after admission, rapid expansion of the aneurysm with sealed rupture were detected by follow-up enhanced CT. The patient immediately underwent an emergency operation. We confirmed fissure on the posterior aneurysmal wall with a localized hematoma. We replaced the aneurysm with a straight prosthetic graft and the postoperative course was uneventful.
