From July 2011 to June 2012, 31 out of 33 green anaconda juveniles from an oceanarium in Hong Kong died over a 12-month period. These anacondas were progeny of a female anaconda purchased from Japan and added to the collection in May 2011. The juvenile anacondas were born in July 2011. A novel paramyxovirus, named anaconda paramyxovirus (AnaPV), was isolated from these affected juvenile anacondas. In July 2015, one of the remaining two anacondas, that survived the cluster of fatal infections, died at the age of four...

In situ fenestration of stent-grafts allows patients with life threatening aortic pathologies to be amenable to emergent "off the shelf indications for use" percutaneous treatments as a bail out technique. Three types of aortic stent-grafts were subjected to laser fenestration in a physiological saline solution followed by balloon angioplasty using 8, 10 or 12 mm in diameter noncompliant balloons. The morphology and the size of fenestrations were observed under optical and scanning electron microscopy. The damage to the fabrics was analyzed and quantified...

Six patients suffering from acute respiratory distress syndrome with the need for extracorporeal membrane oxygenation (ECMO) therapy in deep sedation were included. Isoflurane sedation with the AnaConDa system was initiated within 24 hours after initiation of ECMO therapy and resulted in a satisfactory sedation (Richmond Agitation-Sedation Scale -4 to -5). Despite deep sedation, spontaneous breathing was possible in 6 of 6 patients. We observed a reduced need for vasopressor therapy and improved lung function (PaO2, PaCO2, delta P, and tidal volume) during isoflurane sedation...

The aim of this narrative review was to highlight key points of volatile anesthetics administration in the intensive care unit (ICU), including AnaConDa® and Mirus® devices characteristics and the reported findings on clinical outcomes in critically ill patients. Intravenous sedation in the ICU is associated with issues, such as over- and under-sedation. Halogenated compounds, which can be safely administered by inserting a device in any ICU ventilation circuit, have interesting pharmacodynamic and pharmacokinetic profiles for patients with multi-organ failure...

OBJECTIVE: The fenestrated Anaconda endograft (Vascutek/Terumo, Inchinnan, UK) is intended for the treatment of abdominal aortic aneurysms with an insufficient infrarenal landing zone. The endografts are custom-made with use of high-resolution, 1-mm-slice computed tomography angiography images. For every case, a nonsterile prototype and a three-dimensional (3D) model of the patient's aorta are constructed to allow the engineers as well as the physician to test-implant the device and to review the fit of the graft...

The circle system has been in use for more than 100 years, whereas the first clinical application of an anaesthetic reflector was reported just 15 years ago. In the circle system, all breathing gas is rebreathed after carbon dioxide absorption. A reflector, on the other hand, with the breathing gas flowing to and fro, specifically retains the anaesthetic during expiration and resupplies it during the next inspiration. A high reflection efficiency (number of molecules resupplied/number of molecules exhaled, RE 80-90%) decreases consumption...

We report a misinterpretation of bilateral mydriasis as blown pupils related to elevated intracranial pressure (ICP) under volatile sedation with isoflurane (Anesthetic Conserving Device [AnaConDa], Hudson RCI, Uppland Vasby, Sweden) in a 59-year-old patient with a severe traumatic brain injury with frontal contusion. The patient showed bilateral mydriasis and a missing light reflex 8 hours after changing sedation from intravenous treatment with midazolam and esketamine to volatile administration of isoflurane...

Most vertebrates increase cardiac output during activity by elevating heart rate with relatively stable stroke volume. However, several studies have demonstrated 'intrinsic autoregulation' of cardiac output where artificially increased heart rate is associated with decreased stroke volume, leaving cardiac output unchanged. We explored the capacity of noradrenaline to overcome autoregulation in the anaconda heart. Electrically pacing in situ perfused hearts from the intrinsic heart rate to the maximum attainable resulted in a proportional decrease in stroke volume...

Since the introduction of fenestrated endovascular aneurysm repair (FEVAR) in 1996, great advances have been made in endograft development. Custom-made and off-the-shelf fenestrated and branched endografts have been used to treat patients with complex abdominal aortic and thoraco-abdominal aneurysms. Most experience has been gained with the Cook Zenith® fenestrated endograft (Cook Medical Inc., Limerick, Ireland). The Cook Zenith® endograft is customized with fenestrations, (fixed) inner or outer branches, or a combination of them, to cover a wide range of complex aneurysms...

BACKGROUND: Endovascular aneurysm repair is a minimally-invasive method for the treatment of abdominal aortic aneurysms. For aneurysms that involve the visceral arteries, a custom-made stent graft with fenestrations for the branch arteries is required. The purpose of the current study is to evaluate the structural impact of misaligned fenestrations with respect to luminal patency and proximal aortic neck apposition in an in vitro model. METHODS: A custom apparatus was used to evaluate seven Anaconda and three Zenith fenestrated stent grafts...

BACKGROUND: Prior studies have indicated associations between ingestion of inorganic arsenic and ischemic heart disease, nonmalignant respiratory disease, and lung, skin, bladder, and kidney cancers. In contrast, inhaled arsenic has been consistently associated only with lung cancer. Evidence for health effects of inhaled arsenic derives mainly from occupational studies that are subject to unique biases that may attenuate or obscure such associations. OBJECTIVES: We estimated the excess mortality from respiratory cancers, heart disease, and other causes resulting from occupational arsenic exposure while controlling for confounding using the parametric g-formula...

BACKGROUND: To describe a technique that connects an Anaconda stent graft (Vascutek, Terumo, Inchinnan, Scotland) to a target artery in a hybrid method. CASE REPORT: The patient was a 65-year-old man with a huge pluri-relapsing iliac and femoral pseudoaneurysm of a previous aortobifemoral bypass. An Anaconda stent graft was used to repair the lesion. After partial dissection of the femoral bifurcation, the Anaconda stent graft was partially introduced via a direct puncture in the anterior wall of the femoral artery over a guidewire...

With the AnaConDa™ and the MIRUS™ system, volatile anesthetics can be administered for inhalation sedation in intensive care units. Instead of a circle system, both devices use anesthetic reflectors to save on the anesthetic agent. We studied the efficiency of desflurane reflection with both devices using different tidal volumes (VT), respiratory rates (RR), and 'patient' concentrations (CPat) in a bench study. A test lung was ventilated with four settings (volume control, RR × VT: 10 × 300 mL, 10 × 500 mL, 20 × 500 mL, 10 × 1000 mL)...
