Plasminogen is a circulating zymogen which enters the arterial wall by radial, transmural hydraulic conductance, where it is converted to plasmin by tissue plasminogen activator t-PA on an activation platform involving S100A4 on the vascular smooth muscle cell (vSMC) membrane. Plasmin is involved in the progression of human thoracic aneurysm of the ascending aorta (TAA). vSMCs protect the TAA wall from plasmin-induced proteolytic injury by expressing high levels of antiproteases. Protease nexin-1 (PN-1) is a tissue antiprotease belonging to the serpin superfamily, expressed in the vascular wall, and is able to form a covalent complex with plasmin...

Actuator-driven pulsed water-jet (ADPJ) dissection is an emerging surgical method for dissecting tissue without heat and mechanical injury to vessels. We elucidated the mechanical properties of the piezo ADPJ and evaluated its usefulness and safety in coronary artery bypass grafting procedures. The relationship between the input voltage (10-100 V) and peak pressure of the pulsed water jet was evaluated. The tissue strengths of swine internal thoracic and coronary arteries and the surrounding tissues were measured to assure tissue-selective dissection...

BACKGROUND: Preoperative simulation of the thoracic duct using magnetic resonance thoracic ductography (MRTD) would enable a safe lymph node dissection near the thoracic duct and the prevention of chylothorax after an esophagectomy. The aim of this study was to determine whether MRTD is useful for preventing injury to the thoracic duct during surgery and for reducing the incidence of chylothorax after surgery. METHODS: We evaluated 130 patients who underwent preoperative MRTD followed by a thoracoscopic esophagectomy for the treatment of thoracic esophageal cancer between August 2014 and April 2017 (MRTD group)...

The purpose of the study was to evaluate the value of transarterial chemoembolization (TACE) via right internal thoracic artery (RITA) for patients with unresectable hepatocellular carcinoma (HCC).From January 2000 to June 2016, a retrospective study was conducted of all patients with unresectable HCC who underwent TACE via RITA across 3 medical centers. The technical success, serum alpha-fetoprotein (AFP) level changes, major complications, disease control rate, and survival were evaluated and analyzed.During the study peroid, in all, 21 patients (men 21; mean age 57...

Objective: To investigate the technical method for harvesting and application of the descending branch of the lateral circumflex femoral artery (DBLCFA) in the coronary artery bypass grafting (CABG) operation. Methods: Between December 2016 and April 2017, 19 patients were arranged to use DBLCFA and got CT angiography (CTA) of pelvic and femoral arteries pre-operative at Fuwai Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Finally, DBLCFA was harvested in 16 patients (including 2 female patients, with a mean age of (47...

Purpose To evaluate the performance of a deep learning convolutional neural network (CNN) model compared with a traditional natural language processing (NLP) model in extracting pulmonary embolism (PE) findings from thoracic computed tomography (CT) reports from two institutions. Materials and Methods Contrast material-enhanced CT examinations of the chest performed between January 1, 1998, and January 1, 2016, were selected. Annotations by two human radiologists were made for three categories: the presence, chronicity, and location of PE...

OBJECTIVE AND METHODS: Data on isolated coronary artery bypass grafting (CABG) performed in 2013 and 2014, and registered in the Japan Cardiovascular Surgery Database were reviewed for preoperative characteristics, postoperative outcomes, and choice of graft material for the left anterior descending artery (LAD). RESULTS: Isolated CABG was performed off-pump in 54.7% of cases, and graft material for the LAD was left internal thoracic artery in 74.3% and right internal thoracic artery in 15...

A 71-year-old man presented with a productive cough and fever, and he was diagnosed as having an esophageal perforation and a mediastinal abscess. He had a history of traumatic hemothorax and pleural drainage for empyema in the right chest and was considered unable to tolerate thoracic surgery because of sepsis and progressive aspiration pneumonia. In order to aggressively drain the mediastinal contamination, we performed internal drainage by placing a Levin tube into the mediastinum through the perforation site...

The internal thoracic artery (ITA) that differs from coronary artery (CA), rarely develops atherosclerosis. Understanding the mechanism underlying such a difference will help to pave a new way to the prevention and treatment of the disease. We hypothesize herein that the difference in susceptibility to atherosclerosis between CA and ITA is attributable to the heterogeneity of perivascular adipose tissues (PVATs) surrounding these two kinds of arteries, i.e. PVAT-CA and PVAT-ITA. We isolated PVAT from eight patients of coronary heart disease (CHD) and four non-CHD patients...

Purpose: Four-dimensional computed tomography (CT) images are typically used to quantify the necessary internal target volumes for thoracic and abdominal tumors. However, 4-dimensional CT is typically associated with excessive imaging dose to patients and the situation is exacerbated when using repeat 4-dimensional CT imaging on a weekly or daily basis throughout fractionated therapy. The aim of this work is to evaluate an iterative reconstruction (IR) algorithm that helps reduce the imaging dose to the patient while maintaining imaging quality as quantified by point spread function and contrast-to-noise ratios (CNRs)...

REVIEW
Rustain L Morgan, D Ross Camidge
Accurate assessment of disease response is the foundation of therapeutic trails, which is why the Response Evaluation Criteria in Solid Tumors (RECIST) criteria serves as an international standard investigators can utilize when examining patient outcomes. Nine years after the initial RECIST criteria were released, an update, RECIST 1.1, was published to improve on initial criteria and address technologic advancements in imaging. Since then advancements in both standard clinical and trial practices, combined with improvements in our understanding of cancer biology have resulted in the identification of a number of limitations of the current RECIST 1...

ETHNOPHARMACOLOGICAL RELEVANCE: So-ochim-tang-gamibang (SOCG) is a traditional Korean medicine formulated to control internal energy flow (Qi) and has been prescribed to improve stress-induced depressive disorders. AIM OF THE STUDY: SOCG has been used in clinical practice for the last two decades and its efficacy against stress-induced thoracic pain has been suggested. Although SOCG has been used as an herbal formula in Korean medicine, its toxicity has not yet been evaluated...

AIM: Chronic periaortitis (CP) is a disease characterized by a fibro-inflammatory periaortic cuff and adventitia-predominant fibrosis. CP encompasses idiopathic retroperitoneal fibrosis and inflammatory abdominal aortic aneurysm (AAA), and recent studies have documented overlap between CP and immunoglobulin G4-related disease (IgG4-RD). This study aimed to investigate clinical characteristics and treatment outcomes of patients with CP. METHOD: CP patients were identified by retrospective review of 1245 patients with International Classification of Diseases 10th edition code of aortitis or aortic disease...

Phthalates are widely used in consumer products, and experimental studies suggest that exposure to phthalates increase the risk of allergies. However, epidemiologic evidence on the associations between prenatal phthalate exposure and allergies/infectious diseases and cord blood immunoglobulin E (IgE) levels is limited. This study aimed to evaluate the associations between maternal mono(2-ethylhexyl) phthalate (MEHP) levels and cord blood IgE levels at birth (n=127), as well as the risk of allergies/infectious diseases in participants up to 7years of age; the participants were 1...

INTRODUCTION: Blunt thoracic trauma in the elderly has been associated with adverse outcomes. As an internal quality improvement initiative, direct intensive care unit (ICU) admission of nonmechanically ventilated elderly patients with clinically important thoracic trauma (primarily multiple rib fractures) was recommended. METHODS: A retrospective review of the trauma registry at a level 1 trauma center was performed for patients aged ≥65 y with blunt thoracic trauma, admitted between the 2 y before (2010-2012) and after (2013-2015) the recommendation...
