A 61-year-old man underwent thoracic aortic graft replacement and abdominal aortic graft replacement because of a dissecting aneurysm. He presented with a ruptured residual dissecting thoraco-abdominal aortic aneurysm and underwent emergency thoraco-abdominal aortic graft replacement in February 2007. An inverted bifurcated graft was fashioned by cutting one of the two graft legs and creating an elliptical patch, like a cobra-head. In order to prevent paraplegia after the operation, it was necessary to shorten the duration of spinal cord ischemia. Once the elliptical patch was sutured to the orifices of the internal costal arteries with running sutures, selective intercostal arterial perfusion was initiated by using a cardiopulmonary bypass. After the operation, he did not suffer paraplegia.

A 58-year-old man was admitted because of enlargement in diameter of the descending thoracic aorta. Six years previously, he had undergone graft replacement of the proximal descending aorta due to a chronic dissecting aneurysm. During that surgery, distal fenestration involving resection of the intimal flap of the distal anastomotic site and graft replacement with distal anastomosis of the true and false lumen were performed. Our preoperative enhanced computed tomography (eCT) revealed a thoracic aortic aneurysm 58mm in diameter at the site of distal fenestration. Graft replacement through left lateral thoracotomy was considered difficult because of previous occurrence of methicillin-resistant Staphylococcus aureus (MRSA) empyema after the previous operation: hence, endovascular repair was done using a handmade stent graft to interrupt blood flow into the false lumen. The postoperative course was uneventful. Postoperative eCT showed the thrombosed false lumen and the shrinkage of the aneurysm from 58 to 38mm in diameter over a period of 18 months.

We describe a novel method for repeat median sternotomy. We have successfully used ‘finger’ lifting resternotomy technique and achieved zero major cardiovascular injury/catastrophic hemorrhage events at reoperation. After general anesthesia, all patients were placed in the supine position and two external defibrillator pads were placed on the chest wall. We perform a median skin and subcutaneous incision along the previous sternotomy incision extending 3 cm distal to the sternum. The sternal wires that had been used for the previous closure were left in place but untied. Using a long electric cautery, right thoracotomy was performed under the right costal arch approach. Then, the operator could approximate the sternal wires in the retro-sternal space. At the same time, the operator could confirm the retro-sternal adhesion status which by touching with a finger. Resternotomy was performed using an oscillating saw pointed toward the operator's finger, which allowed safe re-median sternotomy from the lower to the upper part of the sternum. This technique of finger-lifting resternotomy has been employed in 50 cardiovascular reoperations and resulted in 0 incident of major cardiac injury or catastrophic hemorrhage. The finger-lifting resternotomy technique is safe and simple in reoperation procedures and yield excellent early outcomes.

BACKGROUND:
Before the COVID-19 vaccine became available, many Japanese people were undecided about whether or not to receive them. Their decisions were keys to achieving herd immunity. The impact of the type of information source on the COVID-19 vaccine uptake decision-making process remains unclear. We aimed to investigate the association between information source usage on COVID-19 and subsequent vaccine uptake status among those who have yet to decide whether to receive vaccines from non-prioritized people for vaccination.
METHODS:
Prospective cohort online self-administered surveys were conducted in February 2021 (T1), before the start of the mass vaccination program, and September-October 2021 (T2), when the vaccines were available to all citizens. The survey's target population was registered monitors of an Internet research company. Participants who answered "I want to get vaccinated after waiting to see how it goes." at T1 were eligible for analysis. The outcome variable was the COVID-19 vaccine uptake status in T2, and the predictors were 20 types of information sources, categorized based on people (family members, etc.), institutions (governments, etc.), or media (TV news, etc.). Adjusted odds ratio and 95% confidence intervals were estimated using logistic regression adjusted for possible confounders.
RESULTS:
The 5,139 respondents, mean age and standard deviation was 42.8 ± 12.5, 55.7% female, were eligible for analysis. 85.7% completed vaccination (including reserved/intended people) in T2. In the multivariate logistic analysis, odds ratios (95% confidence interval) for vaccine uptake were 1.49 (1.18-1.89) for workplaces/schools, 1.81 (1.33-2.47) for LINE, 0.69 (0.55-0.86) for Internet news and 0.62 (0.48-0.82) for video sharing sites.
CONCLUSIONS
The type of information source usage played an important role in the decision to vaccinate against COVID-19. Although caution is needed in interpreting the results, obtaining information from workplaces/schools and LINE was influential in promoting immunization.

We are under pressure to reform the social security system and work styles. To realize these reforms and basic principles, we need to understand the current environment surrounding the hospital and consider future measures. We report on the problems identified as a result of our investigation of the medical environment in the South West Mikawa West Medical Region and our hospital, and propose the use of emergency medical technicians (EMTs) as a solution to these problems. We examined data from the National Census, the Japan Medical Association Research Institute for General Policy Studies, the Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications, and our hospital’s management meeting. In this medical area the population aged 65 years or older and the demand for medical care are projected to increase toward the year 2045. On the other hand, the number of physicians and nurses per 100,000 population in this medical region is below the national average. Almost no change was seen in the number of patients coming to the hospital by ambulance or the number of emergency admissions by ambulance, and their admission rates did not change significantly over the past 5-year period. However, the rate of unfilled ambulance demand increased, due to the impact of full beds. Of the total number of emergency ambulance admissions, the rate of moderately ill patients averaged 74% over the 5-year period. The number of inpatient transfers in 2022 decreased by 25.5% (176) compared to that in 2019 due to the lack of personnel to transport patients. As the demand for medical care increases toward 2045, we need to reduce the rate of unfilled ambulance demand while at the same time reforming work styles to create a more comfortable workplace for healthcare workers. To achieve these goals, key tasks may be to review the transfer transport system for moderately ill patients and to expand the role of EMTs.

Even within a hospital, the prognosis after a cardiac arrest is extremely poor if intervention starts only after the event; thus, early recognition and intervention is crucial to reduce inhospital cardiac arrests. This paper aims to assess the results of in-clinic surveys conducted for the implementation of the Rapid Response System (RRS) at our hospital and changes in awareness after awareness initiatives. Excluding the neonatal intensive care unit, all wards were targeted for implementation, with the creation of criteria for requesting the RRS and hospital-wide awareness initiatives. Four items were defined for the request criteria—namely, (1) respiration, (2) circulation, (3) state of consciousness, and (4) others (any concerns)—with a request being warranted if any one of these criteria was met. A pre-awareness survey revealed that respiratory rates were recorded only 6.9% of the time on average, indicating inadequate observation of respiratory rates across all wards. In response to this issue, we announced that respiratory status should be observed at least once a day, which resulted in the recording rate improving to 68.2% after 2 months. Survey results before and after the awareness initiatives among doctors and nurses showed a significant increase in RRS awareness. The percentage of nurses who answered “well aware” or “somewhat aware” increased from 34.8% to 77.6%, and from 63.4% to 88.0% among doctors. However, while the introduction of the RRS was relatively well-received by nurses struggling with on-site responses, some doctors questioned the necessity of the RRS. Upon implementation, it is important to make it known that it is a hospital-wide effort. Simplifying and thoroughly utilizing the request criteria can lead to early recognition of abnormalities. Since it is not easy to gain doctors’ understanding, it is necessary to listen to the needs and requests of each department and patiently continue awareness activities before implementation
