Introduction: Hybrid aortic arch repair for the treatment of aorto-bronchial fistulas has been suggested as a safe alternative to open repair. However, surgical morbidity and mortality are still significant and re-intervention is sometimes inevitable. Report: Successful rescue by a hybrid approach is reported in a 76 year old woman who was transferred from another centre with recurrent episodes of left hemiplegia shortly after debranching of the supra-aortic vessels and thoracic aortic stent grafting for an aorto-bronchial fistula associated with a true aneurysm at the level of origin of the left subclavian artery...

Introduction: Although thoracic endovascular aortic repair (TEVAR) has become a promising treatment for complicated acute type B dissection, its role in treating chronic post-dissection thoraco-abdominal aortic aneurysm (TAA) is still limited owing to persistent retrograde flow into the false lumen (FL) through abdominal or iliac re-entry tears. Report: A case of chronic post-dissection TAA treatment, in which a dilated descending FL ruptured into the left thorax, is described...

PURPOSE: The aim of this retrospective study was to examine the impact of graft oversizing on gutter area and stent compression in chimney graft (CG) for complex abdominal aortic aneurysms (CAAA) repair. The influence of stent graft oversizing on type Ia endoleaks and bridging stent occlusion rates were also examined. METHODS: Preoperative and postoperative computed tomographic angiography (CTA) scans of patients requiring chimney grafts for CAAA between June 2009 and April 2013 in our institution were analysed...

Endovascular approach is now a safe and effective technique for the elective treatment of a thoraco-abdominal aneurysm. This technique has significantly reduced the morbi-mortality for elective surgery. Moreover, it can permit to treat patients with a high surgical risk who are not eligible for open surgery. The permanent availability of endovascular material opens the door for treating a complex emergency thoraco-abdominal aneurysm. Here, we present the case of an 81-year-old man who had a rapidly evolving salmonella-infected aortic thoraco-abdominal Type IV pseudoaneurysm...

We are reporting a case of a 65-year-old female who experienced three ST elevation myocardial infarctions (STEMI) during the course of 3 weeks. The first infarct was related to intramural coronary hematoma that propagated proximally after stenting, the second involved progression of this hematoma with obstruction of the vessel lumen, and the third caused subacute stent thrombosis that required "stent cleaning" using the inflated balloon technique.

OBJECTIVE: Late complications after previous endovascular aneurysm repair (EVAR) procedures include type I/III endoleaks causing aneurysm growth and rupture. We reviewed our results from the management of such complications with endovascular aneurysm sealing (EVAS) techniques. METHODS: Analysis of our prospectively maintained aneurysm database was performed (December 2013-May 2017). Primary outcomes were: (1) success of the procedure in excluding the primary complication, (2) perioperative mortality, (3) post-operative complications and (4) survival...

Some polycyclic aromatic hydrocarbons (PAH) are known carcinogens and workplace PAH exposure may increase the risk of cancer. Monitoring early cancer-related changes can indicate whether the exposure is carcinogenic. Here, we enrolled 151 chimney sweeps, 152 controls, and 19 creosote-exposed male workers from Sweden. We measured urinary PAH metabolites using LC/MS/MS, the cancer-related markers telomere length (TL) and mitochondrial DNA copy number (mtDNAcn) using qPCR, and DNA methylation of lung cancer-related genes F2RL3 and AHRR using pyrosequencing...

Introduction The rupture of thoracoabdominal aneurysms (rTAA) represents one of the major challenges to the vascular surgeon. Recent developments in the endovascular armamentarium and the high mortality from open surgery make endovascular treatment an attractive option. Devices to be used in an emergency environment should be "off-the-shelf" and include, among others, EVAR snorkel/chimney and branched endoprosthesis (T-branch, Cook®). METHODS: We describe the case of a 70-year-old patient who was admitted to the emergency room due continuous low back pain with 3 days of evolution...

At hydrothermal vent sites, chimneys consisting of sulfides, sulfates, and oxides are formed upon contact of reduced hydrothermal fluids with oxygenated seawater. The walls and surfaces of these chimneys are an important habitat for vent-associated microorganisms. We used community proteogenomics to investigate and compare the composition, metabolic potential and relative in situ protein abundance of microbial communities colonizing two actively venting hydrothermal chimneys from the Manus Basin back-arc spreading center (Papua New Guinea)...

This report presents 3 procedures with visceral "chimney stenting" in conjunction with an endovascular aneurysm sealing (EVAS) device, known as chEVAS, for treatment of type 1a endoleak. It includes the first published chEVAS in a patient with previous fenestrated endovascular aneurysm repair (FEVAR). Cases include an 80-year-old man 8 years after FEVAR for a juxtarenal abdominal aortic aneurysm (AAA); an 85-year-old woman 9 months after endovascular aneurysm repair (EVAR) for a ruptured infrarenal AAA; and an 84-year-old woman 3 months after EVAR for a symptomatic infrarenal AAA...

BACKGROUND: Risk factors for postoperative cognitive decline after noncardiac surgery are multifactorial and poorly understood. Evidence suggests that perioperative microembolic damage to the brain on movement of wires and catheters during endovascular aortic procedures may play an important role. Endovascular aortic aneurysm repair requires invasive manipulation of wires and cannulas within the aorta, but research into cerebral emboli during aortic aneurysm repair and cognitive or neurologic injury is scarce and limited to thoracic aneurysms...

Carbonic anhydrases (CAs) are extremely fast enzymes, which have attracted much interest in the past due to their medical relevance and their biotechnological potential. An α-type CA gene was isolated from DNA derived from an active hydrothermal vent chimney, in an effort to identify novel CAs with suitable properties for CO2 capture. The gene product was recombinantly produced and characterized, revealing remarkable thermostability, also in the presence of high ionic strength alkaline conditions, which are used in some CO2 capture applications...

Environmental pollution of the air, water, and soil comprise an increasingly urgent challenge to global health, well-being, and productivity. The impact of environmental pollution arguably has its greatest impact across the lifespan on children, women of childbearing age, and pregnant women and their unborn children, not only because of their vulnerability during development, but also because of their subsequent longevity. Ulaanbaatar, Mongolia, is a highly instructive, perhaps extreme, example of what happens with recent, rapid urbanization...

BACKGROUND: The main mechanism of action of propafenone (antiarrhythmic drug) involves the inhibition of the fast inward sodium current during phase 0 of the action potential. Sodium channel-blocking activity is also characteristic for some antiepileptic drugs. Therefore, it could be assumed that propafenone may also affect seizures. In the present study, we evaluated the effect of propafenone on the protective effect of oxcarbazepine, lamotrigine, topiramate and pregabalin against the maximal electroshock-induced seizures in mice...

Newly erupted black smokers (hydrothermal vent chimneys) are sterile during their formation, but house hyperthermophilic microorganisms in substantial amounts in later stages. No direct experimental data exist by which mechanisms hyperthermophiles colonize newly erupted black smokers, but a scenario was proposed recently how this might happen. Here we combine high temperature light microscopy with electron microscopy to show that two hyperthermophilic Archaea, namely Pyrococcus furiosus and Methanocaldococcus villosus are able to adhere onto authentic black smoker material (BSM)...

While more and more investigations are done to study hyperthermophilic exoelectrogenic communities from environments, none have been performed yet on deep-sea hydrothermal vent. Samples of black smoker chimney from Rainbow site on the Atlantic mid-oceanic ridge have been harvested for enriching exoelectrogens in microbial electrolysis cells under hyperthermophilic (80 °C) condition. Two enrichments were performed in a BioElectrochemical System specially designed: one from direct inoculation of crushed chimney and the other one from inoculation of a pre-cultivation on iron (III) oxide...

PURPOSE: To assess the dynamic behavior of chimney grafts during the cardiac cycle. METHODS: Three chimney endovascular aneurysm repair (EVAR) stent-graft configurations (Endurant and Advanta V12, Endurant and Viabahn, and Endurant and BeGraft) were placed in silicone aneurysm models and subjected to physiologic flow. Electrocardiography (ECG)-gated contrast-enhanced computed tomography was used to visualize geometric changes during the cardiac cycle. Endograft and chimney graft surface, gutter volume, chimney graft angulation over the center lumen line, and the D-ratio (the ratio between the lengths of the major and minor axes) were independently assessed by 2 observers at 10 time points in the cardiac cycle...

Ursolic acid (UA) is a plant derived compound which is also a component of the standard human diet. It possesses a wide range of pharmacological properties, i.e., antioxidant, anti-inflammatory, antimicrobial and antitumor, which have been used in folk medicine for centuries. Moreover, influence of UA on central nervous system-related processes, i.e., pain, anxiety and depression, was proved in experimental studies. UA also revealed anticonvulsant properties in animal models of epilepsy and seizures. The aim of the present study was to investigate the influence of UA on seizure thresholds in three acute seizure models in mice, i...
