BACKGROUND CONTEXT: Metastatic spine tumour surgery (MSTS) is associated with substantial blood loss therefore leading to high morbidity and mortality. While intraoperative cell salvage with leucocyte depletion filter (IOCS-LDF) has been studied as an effective mean of reducing blood loss in other surgical settings, including the spine, no study has yet analysed the efficacy of re-infusion of salvaged blood in reducing the need for allogenic blood transfusion in patients who have had surgery for MSTS...

We attempted to investigate cardioprotection of electroacupuncture (EA) for enhanced recovery after surgery on patients undergoing heart valve replacement with cardiopulmonary bypass. Forty-four patients with acquired heart valve replacement were randomly allocated to the EA group or the control group. Patients in the EA group received EA stimulus at bilateral Neiguan (PC6), Ximen (PC4), Shenting (GV24), and Baihui (GV20) acupoints twenty minutes before anesthesia induction to the end of surgery. The primary end point was cardioprotection effect of electroacupuncture postoperatively and the secondary endpoints were quality of recovery and cognitive functioning postoperatively...

The avian centrifugal visual system, which projects from the brain to the retina, has been intensively studied in several Neognathous birds that have a distinct isthmo-optic nucleus (ION). However, birds of the order Palaeognathae seem to lack a proper ION in histologically stained brain sections. We had previously reported in the palaeognathous Chilean Tinamou (Nothoprocta perdicaria) that intraocular injections of Cholera Toxin B subunit retrogradely label a considerable number of neurons, which form a diffuse isthmo-optic complex (IOC)...

Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG). However, the dynamic process and mechanism of fluorescence IOC have not been elucidated in previous publications. Herein, the optical properties of the complex of ICG and bile, dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated. The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration...

BACKGROUND AND AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is recommended for patients considered high-risk for choledocholithiasis after biochemical testing and abdominal ultrasound. Our aim was to determine whether American Society for Gastrointestinal Endoscopy (ASGE) guidelines accurately select patients where the risk of ERCP is justified. METHODS: Consecutive patients hospitalized with suspected choledocholithiasis at Sir Run Run Shaw Hospital who received biochemical testing, abdominal ultrasound, and definitive testing for choledocholithiasis (magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound (EUS), ERCP, intraoperative cholangiogram (IOC), common bile duct (CBD) exploration) were identified...

The infraorbital nerve (ION) can easily be damaged by orbital trauma and periorbital surgical manipulations, due to its abutment to the orbital floor. Anatomic variability of the ION and surrounding structures has infrequently been documented. The aim of this study is to give precise anatomical knowledge about the ION with surrounding structures, to avoid iatrogenic injury of the ION during periorbital procedures.Forty orbits of 40 skull subjects (20 males and 20 females) were studied to analyze structures around the ION...

PURPOSE: Anastomotic leakage (AL) after stapled anastomosis in rectal cancer surgery is a major concern. Various types of intraoperative anastomotic air leakage tests (ALTs) have been proposed to reduce AL. This study aimed to evaluate the impact of intraoperative colonoscopy (IOC) as an intraoperative ALT in low anterior resection for rectal cancer. METHODS: A total of 1266 patients were retrospectively reviewed. Among them, 215 patients who underwent IOC as an ALT in rectal cancer surgery were identified...

Hussain Alquraini, Richard J Auchus
Androgenic-anabolic steroids (AAS) are potent and widely used performance-enhancing substances (PES). Since the International Olympic Committee (IOC) began testing athletes for AAS in the 1970s, athletes and their teams have endeavored to beat the system to avoid doping violations and/or sanctions derived from positive test results. This review will discuss the strategies used to avoid detection based on the pharmacology, biochemistry, and genetics of AAS metabolism and testing principles. Another strategy used is to dope with testosterone under the guise that the athlete has a true medical condition that requires testosterone treatment, using the therapeutic use exemption (TUE) mechanism...

BACKGROUND: Common duct stones can be diagnosed by magnetic resonance cholangiopancreatography (MRCP), endoscopic ultrasound (EUS)/ERCP, and intraoperative cholangiogram (IOC). In 2015, our group adopted a standard approach of preoperative EUS/ERCP followed by laparoscopic cholecystectomy for patients with an admission bilirubin >4.0 mg/dL. For bilirubin <4.0 mg/dL, laparoscopic cholecystectomy with IOC was the initial procedure. Postoperative EUS/ERCP with endoscopic sphincterotomy was pursued for positive IOC...

The United Network for Organ Sharing recommends that fellowship-trained surgeons participate in 15 laparoscopic donor nephrectomy (LDN) procedures to be considered proficient. The American Society of Transplant Surgeons (ASTS) mandates 12 LDNs during an abdominal transplant surgery fellowship. We performed a retrospective intraoperative case analysis to create a risk-adjusted cumulative summation (RACUSUM) model to assess the learning curve of novice transplant surgery fellows (TSFs). Between January 2000 and December 2014, 30 novice TSFs participated in the organ procurement rotation of our ASTS-approved abdominal transplant surgery fellowship...

The objective of the present study was to review the current knowledge regarding the bioaccumulation potential of ionizable organic compounds (IOCs), with a focus on the availability of empirical data for fish. Aspects of the bioaccumulation potential of IOCs in fish that can be characterized relatively well include the pH dependence of gill uptake and elimination, uptake in the gut, and sorption to phospholipids (membrane-water partitioning). Key challenges include the lack of empirical data for biotransformation and binding in plasma...

BACKGROUND: The ideal treatment algorithm for suspected choledocholithiasis is not yet well defined. Imaging options include magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), and intraoperative cholangiogram (IOC). MRCP is diagnostic, while the other two modalities can also be therapeutic. Each of these modalities for diagnosis and treatment carries its own set of risks, benefits, and institutional costs. We hypothesized that there would be a significant difference between the biochemical profiles and characteristics of patients who undergo ERCP vs...

Greater knowledge of biotransformation rates for ionizable organic compounds (IOCs) in fish is required to properly assess the bioaccumulation potential of many environmentally relevant contaminants. In this study, we measured in vitro hepatic clearance rates for 50 IOCs using a pooled batch of liver S9 fractions isolated from rainbow trout (Oncorhynchus mykiss). The IOCs included four types of strongly ionized acids (carboxylates, phenolates, sulfonates, and sulfates), three types of strongly ionized bases (primary, secondary, tertiary amines), and a pair of quaternary ammonium compounds (QACs)...

Application of inorganic-organic clays (IOCs) for the remediation of hexavalent chromium (Cr (VI)) and the effect of bisphenol-A (BPA) were investigated. IOCs were better adsorbents for the removal of Cr (VI) than organoclay. Solution pH significantly affected the surface charge of IOCs and speciation of Cr in the solution; hence, the adsorption of Cr onto IOCs. Pseudo-second order model and Langmuir model were the best fit for the kinetics and equilibrium data, indicating chemisorption and formation of monolayer on homogenous adsorption sites, respectively...
