Cystic echinococcosis (CE) is a parasitic zoonosis caused by the larval stage of the tapeworm Echinococcus granulosus . Detection of the adult stage in the canine definitive host is essential for estimating infection rates, surveillance and monitoring of CE control programs. This study sought to develop and validate a coproantigen sandwich enzyme-linked immunosorbent assay (copro-ELISA), based on antibodies against E. granulosus -soluble membrane antigens (EGMA), that is capable of distinguishing infected and noninfected dogs...

BACKGROUND: Myocardial injury after noncardiac surgery (MINS) is a major contributor to peri-operative morbidity and mortality with a reported incidence of about 8%. Tachycardia increases myocardial oxygen demand, and decreases oxygen supply, and is therefore a potential cause of MINS. OBJECTIVE: We tested the hypothesis that there is an association between intra-operative area above a heart rate (HR) of 90 bpm and a composite of MINS and in-hospital all-cause mortality...

Interventional C-arm imaging is crucial to percutaneous orthopedic procedures as it enables the surgeon to monitor the progress of surgery on the anatomy level. Minimally invasive interventions require repeated acquisition of X-ray images from different anatomical views to verify tool placement. Achieving and reproducing these views often comes at the cost of increased surgical time and radiation. We propose a marker-free 'technician-in-the-loop' Augmented Reality (AR) solution for C-arm repositioning. The X-ray technician operating the C-arm interventionally is equipped with a head-mounted display system capable of recording desired C-arm poses in 3D via an integrated infrared sensor...

The quality and the extent of intra-abdominal visualization are critical to a laparoscopic procedure. Currently, a single laparoscope is inserted into one of the laparoscopic ports to provide intra-abdominal visualization. The extent of this field of view (FoV) is rather restricted and may limit efficiency and the range of operations. Here we report a trocar-camera assembly (TCA) that promises a large FoV, and improved efficiency and range of operations. A video stitching program processes video data from multiple miniature cameras and combines these videos in real-time...

Study Objectives: Manned spaceflights from Earth to Mars will likely become reality within the next decades. Humans will be exposed to prolonged isolation, confinement, and altered photoperiods in artificial atmospheric conditions, with potential adverse effects on sleep and performance. On Earth, polar environments serve as space-analogues to study human adaptation, yet few studies include polysomnography due to operational constraints. Methods: Polysomnography, subjective sleepiness and fatigue and psychomotor performance were measured every six weeks in 13 males ("Hivernauts") during a 13-month winter-over campaign at Concordia (Antarctica)...

Background/Aims: Proton pump inhibitors are widely used to prevent gastric endoscopic submucosal dissection (ESD)-related bleeding, but no standard administration regimens have been established. We aimed to prospectively compare the effects of continuous infusion and intermittent dosing with pantoprazole on preventing gastric ESD-related bleeding. Additionally, we analyzed the risk factors for bleeding. Methods: From April 2012 to May 2013, patients with a gastric epithelial neoplasm scheduled for ESD in the Pusan National University Hospital were randomly assigned to one of two groups according to the pantoprazole administration regimen (continuous infusion or intermittent dosing)...

Parkinson's disease, a neurodegenerative disorder, presents with resting tremor, muscle rigidity and bradykinesia. Affecting multiple organ-systems, it's an important cause of peri-operative morbidity. General anaesthesia may deteriorate cardio-pulmonary and neuro-cognitive functions; moreover, medications used may interact with anti-parkinsonian agents. Spinal anaesthesia is usually avoided in Parkinson's disease. However, it offers neurologic monitoring and less surgical stress response and avoids complications of general anaesthesia...

Fifty-four pigs ( Sus scrofa, Large White cross) from a commercial pig farm were anaesthetised over a six-year period from October 2011. The procedural stages included initial instrumentation for intra-operative monitoring, laparoscopic nephrectomy, preparation of the kidney graft, orthotopic auto-transplantation by either a laparoscopic approach or an open surgical approach, and ligation of the contralateral ureter. During the evolution and establishment of this pig model multiple refinements were introduced: (1) a heat pad was changed to a circulating warm air blanket; (2) routine administration of anticholinesterase and antimuscarinic drugs for reversal of neuromuscular blockade; (3) a technique for urethral catheterisation was developed; (4) ultrasound guidance for placement of a central venous line was learned; (5) intravenous infusions of morphine and ketamine were instituted for a more stable and balanced anaesthetic protocol; and (6) post-operative monitoring was performed by two technical staff for at least the first six hours after extubation of the trachea...
