BACKGROUND: This study reports the mid-term prevalence and therapeutic consequences of anastomotic leaks after surgery for Stanford type A aortic dissections. PATIENTS AND METHODS: From July 2007 to July 2013, 93 patients survived surgery for acute type A dissections at our center and underwent a standardized follow-up. The pre-, peri-, and postoperative as well as the midterm results were collected prospectively. Follow-up computed tomography (CT) imaging was performed 7 days, 3, and 12 months after surgery, and yearly thereafter, to assess the presence or progression of anastomotic leaks at the aorto-prosthesis anastomotic sites...

Miniature GPS devices now allow for measurement of the movement of animals in real time and provide high- quality and high-resolution data. While these new data sets are a great improvement, one still encounters some measurement errors as well as device failures. Moreover, these devices only measure position and require further reconstruction techniques to extract the full dynamical state space with the velocity and acceleration. Direct differentiation of position is generally not adequate. We report on the successful implementation of a shadowing filter algorithm that (1) minimizes measurement errors and (2) reconstructs at the same time the full phase-space from a position recording of a flying pigeon...

Most existing fish vaccines are presented in the form of oil-based emulsions delivered by intraperitoneal injection. Whilst very effective they are frequently associated with inflammatory responses that can result in clinically significant side-effects often involving the adipose tissue that is in direct contact with the vaccine. To explore the potential of immune gene expression changes in the adipose tissue of fish to be markers of vaccination efficacy or development of side-effects we have studied the response to a bacterial (Aeromonas salmonicida) vaccine administered with two different adjuvants...

INTRODUCTION: We report a case of spinal cord infarct as a result of suspected fibrocartilaginous embolism (FCE). CASE PRESENTATION: A 23-year-old man presented with sudden onset cervical and upper back pain followed by progressive weakness in his extremities after throwing a baseball. History, neurologic examination and spinal cord imaging were consistent with spinal cord infarct. We believe the cause was from FCE. DISCUSSION: Though rare, physicians should be familiar with this diagnosis and the proposed mechanisms...

The use of electronic cigarettes (e-cigarettes) is increasing as an alternative to tobacco burning cigarettes; however, their safety remains to be fully determined. The long-term effects of e-cigarettes are unknown, including the effects of maternal e-cigarette use on pre- and postnatal development. Additional research on the safety of e-cigarettes is needed. Especially useful would be information from high- and moderate-throughput economic model systems. This study investigates the effects of 1,2-propanediol, which was identified as the main component of e-cigarette liquid, on early development of zebrafish (an in vivo high-throughput model system that was recently proposed for the study of tobacco cigarette and e-cigarette toxicity)...

INTRODUCTION: Supraventricular tachycardia (SVT) is the most common arrhythmia in the neonatal period, but its association with other triggering processes is not well established. The aim of the study was to analyse the possible relationship between neonatal SVT and gastroesophageal reflux disease (GERD), a condition which was recently linked to atrial arrhythmias. MATERIAL AND METHODS: A retrospective longitudinal descriptive study was conducted over a period of 5years on newborns who were diagnosed with SVT in a level III neonatal unit, assessing morphological aspects, associated symptoms, and treatments received...

IFN-γ is a major effector cytokine, produced to induce type I immune responses. It has been cloned in several fish species including zebrafish, however to date few studies have looked at IFN-γ protein expression and bioactivity in fish. Hence, the current study focused on developing a monoclonal antibody (moAb) against zfIFN-γ. We show that the zfIFN-γ moAb specifically recognises E. coli produced recombinant IFN-γ protein and zfIFN-γ produced in transfected HEK293 cells, by Western blot analysis. Next we analysed the production of the native protein following expression induced by PHA stimulation of leukocytes in vitro or antigen re-stimulation in vivo...

The proposals of the Working group on perioperative hemostasis (Groupe d'intérêt en hémostase péri-opératoire (GIHP)) concerning the perioperative management of patients receiving the direct oral anticoagulants (DOACs) are based on the measure of their anticoagulant activities (anti-Xa for rivaroxaban and anti-IIa for dabigatran) with a safety threshold ≤ 30 ng/mL. If the dosage of the drug is not available, proposals are based on the combination of a PT ≥80% and an aPTT ≤1.20. The aim of our study was to evaluate the performance of PT, aPTT and thrombin time to predict values above or below the safety threshold...

Warfarin is typically prescribed for patients with thromboembolic diseases and atrial fibrillation. In addition to the complications of bleeding, allergic skin reaction is one of its rare adverse effects. We herein report a case of a 79 year old male patient with leukocytoclastic vasculitis and proteinuria secondary to warfarin. The warfarin was discontinued and oral prednisone therapy was initiated. The cutaneous lesions and the proteinuria resolved thereafter.

BACKGROUND: Behcet's disease is a chronic inflammatory disorder usually characterized by the triad of oral ulcers, genital ulcers, and uveitis. Central to the pathogenesis of Behcet's disease is an autoimmune vasculitis. Neurological involvement, so called "Neuro-Behcet's disease", occurs in 10-20% of patients, usually from a meningoencephalitis or venous thrombosis. CASE REPORT: We report the case of a 46-year-old patient with Neuro-Behcet's disease who presented with central neurogenic hyperventilation as a result of brainstem involvement from venulitis...
