Off-pump HeartMate II Exchange in a Patient with Severe Lower Extremity Peripheral Artery Disease: A Case Report

Thrombosis of left ventricular assist device (LVAD) pumps is a serious complication that often requires exchange of the device. A 66-year-old man with severe peripheral vascular disease presented with pump thrombosis of the HeartMate II (HMII) LVAD 1.5 years after implantation. The HMII was exchanged to another HMII through a subcostal incision and without the use of cardiopulmonary bypass. For safety, the patient was prepared for cardiopulmonary bypass by exposing the right subclavian artery and insertion of a 5 FR cannula in the left common femoral vein. The pump was exchanged through a subcostal incision made over the LVAD pump pocket perpendicular to the costal margin. After deairing the pump and graft, LVAD support was resumed, postoperative course was uneventful, and the patient was discharged from the hospital four days later. Re-thrombosis, stroke, and right heart failure are frequent complications after LVAD exchange. Exchange through a subcostal incision with cardiopulmonary bypass backup appears to be safe

A Case Study of Malignant Edema in Postpartum Mediterranean Buffaloes (Bubalus bubalis)

The paper describes for the first time four cases of postparturient malignant edema in water buffaloes due to Clostridium septicum (Cl. septicum). The study was carried out on four primiparous buffaloes that showed swelling of perineal and perivulvar areas, fever and agalactia a few hours after calving. Two of them died within 20 hours after calving. The other two developed edema in the skeletal muscles of one leg and were treated with sulfadiazine-trimethoprim for 10 days. The clinical signs completely resolved. Culture and molecular investigations identified the pathogen isolated from exudate taken from the vulva as Cl. septicum. The isolate showed multi-drug resistance. In the management of infection due to Cl. septicum, timely diagnosis and the chirurgic curettage, associated with a broad-spectrum antibiotic therapy, were found to be sufficient for the survival and recovery of the infected animals

Detección de outliers en grandes bases de datos mediante aproximación basada en celdas

Este artículo aborda la problemática de la detección de outliers en grandes bases de datos. En base a la aproximación por celdas propuesta por Edwin Knorr y Raymond NG en 1998 en el trabajo “Algorithms for Mining Distance-Based Outliers in Large Datasets” se implementaron distintas versiones del algoritmo que superan las limitaciones establecidas en el trabajo original con modificaciones orientadas a mejorar la eficiencia y la utilización del algoritmo en distintos escenarios.Sociedad Argentina de Informática e Investigación Operativa (SADIO

Marine knowledge as a basis for Maritime Spatial Planning: TPEA Project

Comunicación oral presentada en SIEBM XVIII Simposio Ibérico de Biología MarinaThe Transboundary Planning in the European Atlantic (TPEA) project is developing as response to the European Commission (DG Mare’s) call for a Project on Maritime Spatial Planning in the Atlantic, including Celtic Sea and Bay of Biscay, in order to reflect the aim of the project, which is to deliver a commonly-agreed approach to cross-border MSP in the European Atlantic region.DG MARE - E

Aortic Root Dissection Due to an Automated Fastener Device

Minimally invasive aortic valve replacement through a right thoracotomy is frequently performed in patients with aortic valve disease. The Cor-Knot Device (LSI Solutions) is an automated fastener that secures valve sutures. This case report is for a patient who developed postcardiotomy shock during a minimally invasive aortic valve surgery. The patient was found to have an aortic root dissection involving 90% of the aortic root circumference, including bilateral coronary ostia. The autopsy revealed that the aortic damage could be explained by a direct aortic intimal tear from the distal tip of the device shaft. The device was most likely not in perfect apposition to the sewing ring because of the restricted angle and space between the ribs

The optical counterpart of the bright X-ray transient Swift J1745-26

We present a 30-day monitoring campaign of the optical counterpart of the bright X-ray transient Swift J1745-26, starting only 19 minutes after the discovery of the source. We observe the system peaking at i' ~17.6 on day 6 (MJD 56192) to then decay at a rate of ~0.04 mag/day. We show that the optical peak occurs at least 3 days later than the hard X-ray (15-50 keV) flux peak. Our measurements result in an outburst amplitude greater than 4.3 magnitudes, which favours an orbital period < 21 h and a companion star with a spectral type later than ~ A0. Spectroscopic observations taken with the GTC-10.4 m telescope reveal a broad (FWHM ~ 1100 km/s), double-peaked H_alpha emission line from which we constrain the radial velocity semi-amplitude of the donor to be K_2 > 250 km/s. The breadth of the line and the observed optical and X-ray fluxes suggest that Swift J1745-26 is a new black hole candidate located closer than ~7 kpc.Comment: 5 pages, 4 figures, accepted for publication in MNRA
