Abstract
Abstract
Background
Various types of conduits are available for right ventricular outflow tract reconstruction (RVOTR). The bovine jugular vein graft (BJVG) and expanded polytetrafluoroethylene graft (ePTFEG) have been descrived as an alternative to the homograft for RVOTR. Purpose- This study summarized the results to evaluate the single-center operation of RVOTR using BJVG and ePTFEG.
Methods
The valve functions of 27 patients under 20 years old who underwent primary RVOTR with BJVG and 26 patients with ePTFEG at our university hospital between 2013 and 2018 were retrospectively investigated. The valve conditions were assessed using echocardiography and cardiac catheterization.
Results
The median age at the time of operation was 1.8 years old (range, 6 days to 7.8 years old) with BJVG and 2.2 years old (range, 8 months to 9.1 years old) with ePTFEG. The median follow-up time was 3.4 years (range, 2 months to 5.2 years) with BJVG and 2.1 years (range, 1 month to 5.1 years) with ePTFEG. The peak RVOT gradient of BJVG was lower than ePTFEG (10.6±7.7 mmHg versus 18.1±16.2 mmHg, P=0.035). There were no differences in branch pulmonary stenosis defined as peak gradient up to 36mmHg (40.7% versus 50.0%, P=0.50) and pulmonary regurgitation graded worse than moderate (18.5% versus 11.5%, P=0.48) with BJVG and ePTFEG, respectively. Aneurysmal dilatation of the conduit was seen 22.2% with BJVG but none of patients with ePTFEG (P=0.01). All of patients with aneurysmal dilated BJVG had branch pulmonary stenosis. There were no differences in catheter intervention for branch pulmonary stenosis (22.2% versus 30.8%, P=0.48) and conduit replacement (11.1% versus 7.7%, log rank P=0.67) with BJVG and ePTFEG, respectively. There were no deaths during the fllow-up period in both groups.
Conclusions
The outcomes of RVOTR with BJVG and ePTFEG were clinically satisfactory. Aneurysmal dilatation was seen with BJVG and branch pulmonary stenosis was the risk factor for aneurysmal dilatation.

Abstract
Abstract
Background
Successful recanalisation of percutaneous coronary intervention for chronic total occlusion lesions has been associated with improved survival.
Purpose
This study aimed to assess the impact of successful percutaneous coronary intervention for chronic total occlusion lesions on the long-term outcome of patients with impaired and preserved left ventricular ejection fraction (LVEF).
Methods
The study sample consisted of 842 consecutive patients (928 chronic total occlusion lesions) undergoing percutaneous coronary intervention at our institution between October 2005 and December 2009. We divided them into 3 groups by the degree of LVEF: less than 40% (severely reduced LVEF, n=140), 40% to 59% (moderately reduced LVEF, n=470), and 60% and above (normal LVEF, n=232). We evaluated mortality during the 10-year follow-up period the basis of procedural success and failure.
Results
The overall procedural success rate was 89.1%. Median follow-up duration was 7.9 years. The 10-year cumulative incidences of cardiac death in each degree of LVEF are shown in the Figure.
Conclusions
Successful recanalisation for chronic total occlusion lesions in patients with impaired LVEF may be associated with reduced cardiac mortality.

Abstract
Cerebral arterial air embolism is a rare and unexpected complication of advanced esophageal cancer. The entry of air to systemic circulation is an esophago-left atrial or pulmonary vein fistula formation. Herein, we report an autopsy case of a 64-year-old man. He was diagnosed esophageal cancer 2 years ago and underwent chemotherapy and concurrent chemoradiotherapy but the disease progressed, unfortunately. Then two metal stents were inserted into the middle thoracic esophagus as a palliation of dysphagia. After initiation of oral intake, he developed deterioration of consciousness. The cranial computed tomography showed cerebral arterial air emboli with multiple low-density areas. He failed to gain consciousness again and died one and half days later. In a literature survey, this autopsy case is the first presentation that confirmed histologically the close association between stent placement and formation of esophago-left atrial fistula. Due to the fatality of cerebral arterial air embolism, clinicians should keep in mind the possibility of this catastrophic complication after multimodality treatment of esophageal cancer.

Abstract
BACKGROUND AND AIMS Gastric bypass is known to have larger effects on weight and metabolism than gastric banding. However, scarce data exist as to whether the differences are translated into differential risks of cardiovascular disease (CVD)-related morbidities. The objective was to examine whether adults with obesity and CVD who underwent gastric bypass have a lower rate of acute care use (emergency department [ED] visit or unplanned hospitalization) for CVD than those with gastric banding. METHODS AND RESULTS We performed a comparative effectiveness study of gastric bypass versus banding among adults with obesity and CVD who underwent either surgery, using population-based [ED] and inpatient samples in California, Florida, and Nebraska from 2005 through 2011. The primary outcome was acute care use for CVD during a two-year postoperative period. We constructed negative binomial regression models to compare the event rate during sequential 6-month periods, using gastric banding group as the reference. We identified 11,229 adults with obesity and CVD who underwent gastric bypass and 3896 adults who had gastric banding. Patients with gastric bypass had significantly lower rate of the outcome compared to those with banding in the 7-12 months postoperative period (adjusted rate ratio [aRR] 0.77; 95% confidence interval [CI], 0.61-0.98; P = 0.03). The significant reduction in the rate persisted during 13-18 months (aRR 0.71; 95% CI, 0.57-0.90; P = 0.005) and 19-24 months (aRR 0.66; 95% CI, 0.52-0.82; P < 0.001) after bariatric surgery. CONCLUSION In this population-based comparative effectiveness study of adults with obesity and CVD, the rate of acute care use for CVD was lower after gastric bypass compared to gastric banding.

Abstract
A 63-year-old man had abdominal pain and sequential constipation and diarrhea. He complained of abdominal pain and vomiting, and was admitted to the hospital with a diagnosis of ileus. CT demonstrated a colonic obstruction at the splenic flexure, which was suspected to be colon cancer. Ileostomy was performed in March 2015, and he underwent radical resection in May 2015. Cancer of the pancreas tail had invaded the spleen, colon, stomach, and left renal capsule. Distal pancreatectomy was performed, along with extended right hemicolectomy, left nephrectomy, partial gastrectomy, and stoma closure. He received adjuvant chemotherapy for 6 months after the operation. He is alive without recurrence of pancreatic cancer for over 3 years.

Abstract
We present here a late preterm infant with extensive brain lesions resulting from vitamin K deficiency. A female infant was born after 35 weeks of gestation by emergent cesarean section because of non-reassuring fetal status. Her mother had severe eating disorder and recurrent vomiting since early pregnancy. She was immediately intubated and ventilated because she was extremely pale, hypotonic, and non-reactive. Cerebral magnetic resonance imaging immediately after birth showed intraparenchymal hemorrhage in the left frontal lobe and cerebellum, marked cerebral edema, and cerebellar hypoplasia. Coagulation studies of the infant showed hepaplastin test <5%, prolonged PT and APTT, and a marked elevation of protein induced by vitamin K absence or antagonist-II. This case highlighted a potential risk of intracranial bleeding due to maternal vitamin K deficiency and difficulty in its prediction before delivery. Vitamin K supplementation to high risk mothers might be indispensable for preventing severe fetal vitamin K deficiency. Even when coagulation studies in mothers is normal, it is imperative to provide vitamin K supplementation for total protection.

Abstract
The aim of this study is to estimate tube current modulation (TCM) profiles in paediatric computed tomography (CT) examinations with a TCM scheme (Volume-EC) and evaluate the estimation accuracy of TCM profiles. Another aim is to validate organ doses calculated using Monte Carlo-based CT dosimetry software and estimated TCM profiles by comparing them with those measured using 5-year-old and 10-year-old anthropomorphic phantoms and radio-photoluminescence glass dosemeters. Dose calculations were performed by inputting detailed descriptions of a CT scanner, scan parameters and CT images of the phantoms into the software. Organ doses were evaluated from the calculated dose distribution images. Average relative differences (RDs) between the estimated and actual TCM profiles ranged from -3.6 to 5.6%. RDs between the calculated and measured organ doses ranged from -4.2 to 13.0% and -18.1 to 4.9% for 5-year-old and 10-year-old phantoms, respectively. These results validate dose calculations for paediatric CT scans using TCM.

Abstract
Long-term follow-up of patients with adhesive capsulitis (AC) reveals that approximately half of them suffer from a limited range of shoulder motion, particularly external and/or internal rotation. We report the surgical technique and short-term clinical outcomes of ultrasound-guided release of the thickened coracohumeral (CH) ligament in 8 patients (9 shoulders) with AC. Passive external rotation with the arm by the side significantly increased from an average of 18° preoperatively to 47° immediately after CH ligament release. VAS and ASES scores were improved at 3months follow-up in all 9 shoulders, and maintained at 6months follow-up in 6 shoulders. No procedure-related adverse events developed over the 6-month follow-up period. Ultrasound-guided release for thickened CH ligament is a reliable and effective minimally invasive surgery for persistent limited external rotation due to AC of the shoulder.

Abstract
BACKGROUND Whether direct-acting anti-viral therapy can reduce liver fibrosis and steatosis in patients with chronic hepatitis C virus (HCV) infection is unclear. AIMS To evaluate changes in liver stiffness and steatosis in patients with HCV who received direct-acting anti-viral therapy and achieved sustained virological response (SVR). METHODS A total of 198 patients infected with HCV genotype 1 or 2 who achieved SVR after direct-acting anti-viral therapy were analysed. Liver stiffness as evaluated by magnetic resonance elastography, steatosis as evaluated by magnetic resonance imaging-determined proton density fat fraction (PDFF), insulin resistance, and laboratory data were assessed before treatment (baseline) and at 24 weeks after the end of treatment (SVR24). RESULTS Alanine aminotransferase and homeostatic model assessment-insulin resistance levels decreased significantly from baseline to SVR24. Conversely, platelet count, which is inversely associated with liver fibrosis, increased significantly from baseline to SVR24. In patients with high triglyceride levels (≥150 mg/dL), triglyceride levels significantly decreased from baseline to SVR24 (P = 0.004). The median (interquartile range) liver stiffness values at baseline and SVR24 were 3.10 (2.70-4.18) kPa and 2.80 (2.40-3.77) kPa respectively (P < 0.001). The PDFF values at baseline and SVR 24 were 2.4 (1.7-3.4)% and 1.9 (1.3-2.8)% respectively (P < 0.001). In addition, 68% (19/28) of patients with fatty liver at baseline (PDFF ≥5.2%; n = 28) no longer had fatty liver (PDFF <5.2%) at SVR24. CONCLUSION Viral eradication reduces both liver stiffness and steatosis in patients with chronic HCV who received direct-acting anti-viral therapy (UMIN000017020).

Abstract
BACKGROUND Asthma is characterized by airway inflammation and obstruction with eosinophil infiltration into the airway. Arachidonic acid, an omega-6 fatty acid, is metabolized into cysteinyl leukotriene with pro-inflammatory properties for allergic inflammation, whereas the omega-3 fatty acid eicosapentaenoic acid (EPA) and its downstream metabolites are known to have anti-inflammatory effects. In this study, we investigated the mechanism underlying the counter-regulatory roles of EPA in inflamed lungs. METHODS Male C57BL6 mice were sensitized and challenged by ovalbumin (OVA). After EPA treatment, we evaluated the cell count of Bronchoalveolar lavage fluid (BALF), mRNA expressions in the lungs by q-PCR, and the amounts of lipid mediators by liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based lipidomics. We investigated the effect of the metabolite of EPA by in vivo and in vitro studies. RESULTS Eicosapentaenoic acid treatment reduced the accumulation of eosinophils in the airway and decreased mRNA expression of selected inflammatory mediators in the lung. Lipidomics clarified the metabolomic profile in the lungs. Among EPA-derived metabolites, 12-hydroxy-17,18-epoxyeicosatetraenoic acid (12-OH-17,18-EpETE) was identified as one of the major biosynthesized molecules; the production of this molecule was amplified by EPA administration and allergic inflammation. Intravenous administration of 12-OH-17,18-EpETE attenuated airway eosinophilic inflammation through downregulation of C-C chemokine motif 11 (CCL11) mRNA expression in the lungs. In vitro, this molecule also inhibited the release of CCL11 from human airway epithelial cells stimulated with interleukin-4. CONCLUSION These results demonstrated that EPA alleviated airway eosinophilic inflammation through its conversion into bioactive metabolites. Additionally, our results suggest that 12-OH-17,18-EpETE is a potential therapeutic target for the management of asthma.
