A 62-year-old man was referred to us because of acute aortic dissection (Stanford type A). He had had liver cirrhosis (Child-Pugh class B) and hepatic cell carcinoma in the left lateral lobe, which had been resected 3 years ago. On admission he was drowsy and was in shock. CT showed dissection from the ascending aorta to the abdominal aorta. Echocardiography revealed severe aortic regurgitation. An emergency operation was indicated although it was a very high risk procedure. Under cardiopulmonary bypass with moderate hypothermia, the aortic root was replaced with a Freestyle valve (23mm). Then the ascending aorta was replaced with a woven Dacron graft (28mm) under cardiac arrest and isolated cerebral perfusion. Postoperatively, he had cardiac tamponade and cerebral infarction (perhaps due to the preoperative events). However, he was successfully discharged on the 34th postoperative day.

A 73-year-old woman was referred to our hospital for angina pectoris due to triple-vessel-disease. She underwent off-pump coronary artery bypass grafting ×3 (RITA-LAD, LITA-OM, SV-PDA). Her vital signs were stable during the operation and the postoperative status was steady in the ICU. However, on the next day, she suddenly had severe back pain with markedly elevated blood pressure. Urine output immediately shut down and respiratory failure progressed with time. An enhanced CT scan revealed aortic dissection (DeBakey type I and Stanford type A). An emergency operation was performed via re-sternotomy. Cardiopulmonary bypass was initiated and the body was cooled down to 20°C. Under circulatory arrest with isolated cerebral perfusion, the ascending aorta was replaced using a one-branched Hemashield graft (26mm in diameter). The entry of the dissection was located at the proximal anastomosis site of the vein graft. The postoperative course was uneventful and she was discharged on the 24th postoperative day.

A 68-year-old man was referred to our hospital with an abnormal shadow on chest X-ray film. Enhanced chest CT scan revealed intrathoracic left subclavian artery aneurysm (maximum diameter 4cm) just above the aortic arch. Surgery was indicated considering the risks of aneurysm rupture and distal embolism, although he was asymptomatic. Under left 4th posterolateral thoracotomy, the aneurysm was exposed. Cardiopulmonary bypass was initiated with cannulation of the left femoral artery and vein (to the right atrium). Circulatory arrest and isolated cerebral perfusion were achieved at 25°C core-temperature. The distal arch was replaced using a 26mm Hemashield graft and the left subclavian artery was reconstructed interposing an 8mm graft. The postoperative course was uneventful: he was extubated at 8h and was sent to the ward the next day. He was given an ambulatory discharge on the 13th postoperative day.

A 92-year-old woman was referred to our hospital with lower abdominal pain and lumbago. Her vital signs were stable at an emergency outpatient-clinic. An enhanced CT scan showed a sealed rupture of a right internal iliac artery aneurysm (85×73mm in diameter). An emergency operation was performed via median laparotomy. As predicted pre-operatively, a large hematoma was found in the retroperitoneal space and mesenterium surrounding the right internal iliac artery aneurysm (sealed rupture). Y-grafting was performed using a 16×8mm Intergard: proximal and distal ends of the graft were the abdominal aorta and bilateral femoral arteries, respectively. Left common iliac artery, right external iliac artery and right internal arterial aneurysm were suture-closed. The postoperative course was uneventful and she was discharged on the 13th postoperative day on foot.

A 73-year-old woman was referred to our hospital with a feeling of chest compression. Coronary angiography revealed a giant coronary artery aneurysm, located in the middle of a coronarypulmonary artery fistula originating at the left anterior descending artery. Also another fistula was shown between the right coronary artery and the pulmonary artery. Surgical correction was indicated due to the risks of the aneurysm rupture and coronary events. Under cardiopulmonary bypass, suture-closure of the coronary artery aneurysm and ligation of the fistulae were carried out with success. Transesophageal echocardiography was useful to confirm disappearance of the abnormal shunts after the operative procedures. The postoperative course was uneventful. Postoperative coronary angiography showed no aneurysm or fistula. She was discharged on the 11th postoperative day on foot.

Sixteen cases of malignant soft tissue sarcoma (STS; 10 canines and six felines) were treated with a novel triple therapy that combined photodynamic therapy, hyperthermia using indocyanine green with a broadband light source, and local chemotherapy after surgical tumor resection. This triple therapy was called photodynamic hyperthermal chemotherapy (PHCT). In all cases, the surgical margin was insufficient. In one feline case, PHCT was performed without surgical resection. PHCT was performed over an interval of 1 to 2 weeks and was repeated three to 21 times. No severe side effects, including severe skin burns, necrosis, or skin suture rupture, were observed in any of the animals. No disease recurrence was observed in seven out of 10 (70.0%) dogs and three out of six (50.0%) cats over the follow-up periods ranging from 238 to 1901 days. These results suggest that PHCT decreases the risk of STS recurrence. PHCT should therefore be considered an adjuvant therapy for treating companion animals with STS in veterinary medicine.

Hemodialysis patients need to acquire exercise habits because physical inactivity in hemodialysis patients is associated with increased mortality. However, factors associated with exercise habits in hemodialysis patients are unknown. The purpose of this study was to investigate the factors related to exercise habits in hemodialysis patients. We measured 104 hemodialysis patients' exercise habits (transtheoretical model:TTM), laboratory data, self-efficacy (SE), short physical performance battery and grip strength, nutritional index, dialysis vintage, fluid removal, and Kt/V. Multiple linear regression analysis was carried out to assess the association of the aforementioned factors with TTM. As a result, in multiple linear regression analysis, SE, age, and Kt/V were associated with TTM (R2=0.34, p<0.05). hemodialysis patients may require mental support, such as SE and adequate dialysis dose, to acquire exercise habits.

Bovine abortion, diarrhea, and respiratory disease complexes, caused by infectious agents, result in high and significant economic losses for the cattle industry. These pathogens are likely transmitted by various vectors and reservoirs including insects, birds, and rodents. However, experimental data supporting this possibility are scarce. We collected 117 samples and screened them for 44 bovine abortive, diarrheal, and respiratory disease complex pathogens by using Dembo polymerase chain reaction (PCR), which is based on TaqMan real-time PCR. Fifty-seven samples were positive for at least one pathogen, including bovine viral diarrhea virus, bovine enterovirus, Salmonella enterica ser. Dublin, Salmonella enterica ser. Typhimurium, and Neospora caninum; some samples were positive for multiple pathogens. Bovine viral diarrhea virus and bovine enterovirus were the most frequently detected pathogens, especially in flies, suggesting an important role of flies in the transmission of these viruses. Additionally, we detected the N. caninum genome from a cockroach sample for the first time. Our data suggest that insects (particularly flies), birds, and rodents are potential vectors and reservoirs of abortion, diarrhea, and respiratory infectious agents, and that they may transmit more than one pathogen at the same time.

Objective: To evaluate the efficacy of fan therapy for the relief of dyspnea in patients with chronic progressive disease. Methods: A systematic electronic database search of all available articles published before October 23, 2019 was conducted using Ichushi-Web of the Japan Medical Abstract Society databases, CENTRAL, EMBASE, and MEDLINE. In addition, a hand-search for updates was performed using PubMed on June 30, 2020 and December 7, 2021. The inclusion criteria were: 1) any RCTs comparing the effect of fan therapy with any other intervention, and 2) patients aged ≥18 years. Exclusion criteria were: 1) duplicate references, and 2) conference presentations. Results: We identified 110 studies, of which 10 met our criteria for inclusion. Finally, five studies were used in the meta-analysis. Fan therapy significantly improved dyspnea in patients with chronic progressive disease compared to control groups with a standardized mean difference of −1.43 (95% confidence interval: −2.70 to −0.17, I2=94%, p<0.0001). Conclusion: Fan therapy was found to be effective in reducing dyspnea in chronic progressive disease.
