Background: Sepsis is associated with a highest mortality rate in the ICU. Present study tests the efficacy of combined therapy with vitamin C, hydrocortisone and thiamine (combined therapy) in the ovine model of sepsis induced by Pseudomonas aeruginosa. In this study, sepsis was induced in sheep by instillation of Pseudomonas aeruginosa (1 × ­1011 CFU) into the lungs via bronchoscope, under anesthesia. Nine hours after injury, intravenous infusion of vitamin C (0.75 g every 6 h), hydrocortisone (25 mg every 6 h), and thiamine (100 mg every 12 h) or saline was given to the treatment and control groups. Cardiopulmonary variables were recorded. Results: The survival rate was 16.7% in control and 33.3% in treatment groups. In the control group, mean arterial pressure dropped from 93.6 ± 8.6 to 75.5 ± 9.7 mmHg by 9 h, which was not affected by the combined therapy.Pulmonary dysfunction was not attenuated by the combined therapy either. The combined therapy had no effect on increased extravascular lung water content and fluid effusion into thoracic cavity. The bacterial number in the bronchoalveolar lavage fluid was significantly increased in the treatment group than the control group. The blood bacterial number remained comparable between groups. Conclusions Combined vitamin C, hydrocortisone, and thiamine did not attenuate severity of ovine sepsis.

Background/Aims: The frequency and details of nonalcoholic fatty liver disease (NAFLD) complications in patients with inflammatory bowel disease (IBD) remain unclear. This study aimed to clarify characteristics of NAFLD in patients with IBD. Methods: We retrospectively identified and enrolled patients with IBD diagnosed with or without NAFLD by undergoing abdominal computed tomography (CT) at our institution between 2005 and 2020. The primary endpoint was the complication rate of NAFLD in patients with IBD. Secondary endpoints were the clinical characteristics of nonobese patients with IBD and comorbid NAFLD and their association with nutritional and inflammatory parameters. Results: Twenty-one (21.9%) of 96 eligible patients with IBD also had NAFLD. In nonobese patients (defined as patients with a body mass index <25 kg/m2), C-reactive protein (CRP; P<0.001) and alanine aminotransferase (P=0.018) levels were higher and the albumin level (P=0.005) and prognostic nutritional index (PNI; P=0.002) values were lower in patients with NAFLD than in those without NAFLD. The PNI value was positively correlated (P<0.001) and the CRP level was negatively correlated (P=0.001) with the hepatosplenic ratio. However, in the NAFLD combined group, PNI (P<0.05) and CRP values (P<0.001) were improved over time after CT imaging by continuing IBD treatment. Conclusions Worsening nutritional and inflammatory status in IBD patients is associated with complications of NAFLD. Diagnosis of NAFLD in IBD patients using CT imaging might be useful not only for early detection of NAFLD but also in assessing the need for therapeutic intervention for IBD.

Objectives: Chronic obstructive pulmonary disease (COPD) is a risk factor for osteoporosis. Nevertheless, much remains unclear regarding the bone metabolism dynamics associated with COPD. The present study focuses on the associations between the COPD severity and serum bone metabolism biomarkers. Methods: We enrolled 40 patients who visited the orthopedics departments at our institutions and underwent dual-energy X-ray absorptiometry between September 2015 and December 2017. Only male osteoporosis patients over 45 years of age were included, and 5 patients were excluded due to disease or use of internal medicines affecting bone metabolism. All subjects underwent lung function testing, spine radiography, and blood tests. We measured percent forced expiratory volume in 1 second (%FEV1), which reflects COPD severity, and we examined the relationships between %FEV1and serum levels of bone metabolism biomarkers. Results: All subjects were diagnosed with osteoporosis based on T-scores. %FEV1 correlated with body weight, body mass index (BMI), and Z-score/T-scores. %FEV1 moderately correlated with serum levels of alkaline phosphatase (ALP), procollagen type 1 N-terminal propeptide (P1NP), and tartrate-resistant acid phosphatase 5b in the partial correlation analysis adjusted for BMI or T-score in the lumbar vertebrae. We performed a hierarchical multiple regression analysis to identify that serum ALP and P1NP were the independent explanatory variables to %FEV1 independent of other factors. Conclusions The data suggest that the COPD severity in middle-aged and older men with osteoporosis associates with decreased bone formation. COPD patients may exhibit bone metabolism dynamics characterized by low bone turnover with osteogenesis dysfunction as COPD becomes severe.

An aortoesophageal fistula is a critical condition with high operative mortality. A case of aortoesophageal fistula following thoracic endovascular aneurysm repair is reported. The patient was a 72-year-old man complaining of dysphagia who underwent stent grafting for a saccular aneurysm of the descending aorta that was compressing the esophagus four months earlier. Endoscopic examination showed perforation of the aneurysm into the esophagus with severe stenosis. The aneurysmal sac was filled with thrombus. Aortography demonstrated a type I endoleak from the lesser curvature of the aortic arch, draining into the aneurysmal sac. The patient was afebrile with moderate elevation of C-reactive protein, and the white blood cell count was normal. The patient underwent closure of the aneurysmal entry with healthy aortic wall and replacement of the descending aortic aneurysm with a prosthetic graft. The graft was isolated from the fistula by an omental flap. The patient's postoperative course was uneventful. Computed tomography performed 4 years after the surgery showed shrinkage of the aneurysmal sac. The patient has had a healthy life for 9 years since the operation.

BACKGROUND/AIMS: There is a controversy about the availability of invasive treatment for esophageal/gastric varices in patients with Child-Pugh class C (CP-C) end-stage liver cirrhosis (LC). We have evaluated the validity of invasive treatment with CP-C end-stage LC patients. METHODS: The study enrolled 51 patients with CP-C end-stage LC who had undergone invasive treatment. The treatment modalities included endoscopic variceal ligation in 22 patients, endoscopic injection sclerotherapy in 17 patients, and balloon-occluded retrograde transvenous obliteration (BRTO) in 12 patients. We have investigated the overall survival (OS) rates and risk factors that contributed to death within one year after treatment. RESULTS: The OS rate in all patients at one, three, and five years was 72.6%, 30.2%, and 15.1%, respectively. The OS rate in patients who received endoscopic treatment and the BRTO group at one, three, and five years was 67.6%, 28.2% and 14.1% and 90.0%, 36.0% and 18.0%, respectively. The average of Child-Pugh scores (CPS) from before treatment to one month after variceal treatment significantly improved from 10.53 to 10.02 (P=0.003). Three significant factors that contributed to death within one year after treatment included the presence of bleeding varices, high CPS (≥11), and high serum total bilirubin levels (≥4.0 mg/dL). CONCLUSIONS: The study demonstrated that patients with a CPS of up to 10 and less than 4.0 mg/dL of serum total bilirubin levels may not have a negative impact on prognosis after invasive treatment for esophageal/gastric varices despite their CP-C end-stage LC.

The durability of the Starr-Edwards (SE) mitral caged-disk valve, model 6520, is not clearly known. We reported that SE mitral caged-disk valves implanted ＞20 years previously should be carefully followed up, and that SE caged-disk valves implanted ＞30 years previously should be electively replaced with modern prosthetic valves in our experience. We found the removed valve 39 years after implantation, which seemed minimal structural deterioration. The patient was discharged on the 10th postoperative day without any complications.

A 75-year-old man with underlying arteriosclerosis obliterans presented with acute heart failure secondary to rest pain of the right lower extremity. Echocardiogram showed severe mitral regurgitation, moderate tricuspid regurgitation and a low cardiac function (ejection fraction : 27%). Right toe gangrene developed in association with continuous acute heart failure. He underwent mitral valve replacement, tricuspid annuloplasty, right common femoral artery-posterior tibial artery bypass and amputation of the right toes in single-stage surgery. There were no major complications during his hospital stay. After surgery, his symptoms significantly improved.

Objective : Transarterial or transapical aortic valve replacement (TAVR) procedures have been performed for high-risk patients with severe aortic valve stenosis (AS) in western countries. A high-risk patient is defined as having an STS score greater than 10%. In Japan, aortic valve replacement (AVR) with cardiopulmonary bypass (CPB) is standard care for AS, even if the patient is at high risk of developing complications. We calculated an expected operative risk of patients using a JAPAN score established by Japanese Adult Cardiovascular Surgery Database (JACVSD). Patients and Methods : Patients were divided into three groups : score less than 5%, low risk (LR) ; score 5-10%, moderate risk (MR) ; score more than 10%, high risk (HR). We also evaluated the efficacy of conventional AVR in each group. Between January 2002 and May 2011, we performed conventional AVR in our hospital and 116 patients who underwent AVR for symptomatic AS were enrolled in this study. Results : There were 79 patients in the LR group, 30 patients in the MR group and 7 patients in the HR group. The mean score was 2.6±1.1% in the LR group, 6.8±1.4% in the MR group and 23.3±16.8% in the HR group respectively. The mean follow-up period was 7.6±0.3 years. Preoperative co-morbidity was not statistically significant among three groups, however more octogenarians were found in the HR group. The aortic valve area and left ventricular ejection fraction (LVEF) were significantly smaller in the HR group. There were 4 cancer patients. The HR group had significantly longer operation and CPB times than the LR group. The operative mortality in all cases was 1.6%. Overall survival at 5 years was 78%. Actual survival at 5 years was 77% in the LR group, 82% in the MR group and 71% in the HR group. The major adverse cardiac and cerebrovascular event (MACCE)-free ratio at 5 years was 85%. Absence of death caused by MACCE at 5 years was 93%. All cancer patients died after AVR due to advancement in cancer. Conclusion : The results of conventional AVR with CPB were satisfactory in each group. Cancer patients may be good candidates for TAVR in the future.

Aortic dissection during cardiac operation is a rare but serious complication. Early detection and adequate repair is essential in this situation. A 69-year-old man in whom an aortic valve sparing operation for aortic root dilatation with aortic regurgitation had been begun, had an intraoperative aortic dissection 10min after the start of right axillary artery perfusion. Intraoperative transesophageal echocardiography and direct epi-aortic echo revealed acute aortic dissection extending from the aortic root to at least the descending aorta. The dissection was successfully repaired by a Bentall operation and hemiarch replacement using hypothermic circulatory arrest, selective cerebral perfusion, and antegrade perfusion from an anastomosed graft.
