Despite recent legislation introduced in Scotland and motivated recycling at home, very little recycling exists within theatre environments. This study audited the introduction of recycling of paper and cardboard. All waste within a single operating theatre was collected by a dedicated team for 20 surgical cases. The collection of clean paper and cardboard packaging was limited to the theatre preparation room (TPR) and anaesthetic room (AR). No waste segregation was attempted within the operating theatre itself...

Yutaka Tomizawa, Gregory G Ginsberg
BACKGROUND AND AIMS: Sporadic non-ampullary duodenal adenomas (SNADAs), although uncommon, pose clinical challenges. Because SNADAs have malignant potential, endoscopic or surgical resection is generally recommended. Endoscopic mucosal resection (EMR) is increasingly used for resection of SNADAs, but large-scale data on natural history after EMR are scarce. In this study, we aimed to evaluate the clinical outcome of EMR for SNADAs and the natural history after EMR from a large single-operator experience with dedicated follow-up...

BACKGROUND: Deep enteroscopy-assisted ERCP (DEA-ERCP) in post-bariatric Roux-en-Y (RY) anatomy is challenging. Laparoscopy-assisted ERCP (LA-ERCP) or EUS-directed transgastric ERCP (EDGE) are technically easier and faster, but are more invasive and morbid procedures. Therefore, we have used DEA-ERCP as our first-line approach, reserving EDGE and LA-ERCP for cases in which adjunctive techniques that cannot be performed through an enteroscope are required (eg, EUS-FNA, SO manometry), or DEA-ERCP failures...

There is little evidence about sensation in individuals with diabetes mellitus (DM) in the dental research field. We investigated whether pain thresholds (PTs) differ between individuals with and without DM (non-DM; NDM). To this end, we assessed whether PTs obtained from the oral cavity, hands, and feet differed from each other and across groups, and whether PTs differed for the three current frequencies used for testing (2000 Hz, 250 Hz, and 5 Hz). PT measurements were obtained from the oral mucosa and the tips of the fingers and toes of 56 volunteers, including 21 individuals with DM (12 men and 9 women, average age: 72...

OBJECTIVES: To evaluate operator pelvic radiation exposure during percutaneous coronary procedures. BACKGROUND: During percutaneous coronary procedures, the operator's pelvic region is close to the x-ray source and is probably exposed to more radiation than the operator's thorax. However, no data are available on the pelvic radiation exposure of interventional cardiologists. METHODS: The RADIANT study (NCT01974453) is a prospective, single-center, observational study evaluating operator radiation exposure during percutaneous coronary procedures using electronic dosimeters placed at thorax level...

Since the seminal studies by Pauling in 1930s, planarity has become the defining characteristic of the amide bond. Planarity of amides has central implications for the reactivity and chemical properties of amides of relevance to a range of chemical disciplines. While the vast majority of amides are planar, non-planarity has a profound effect on the properties of the amide bond, with the most common method to restrict the amide bond relying on the incorporation of the amide function into a rigid cyclic ring system...

Optically active, tertiary amine Lewis bases react with unsaturated acid chlorides to deliver chiral, α, β-unsaturated acylammonium salts. These intermediates participate in a catalytic, enantioselective, three-component process delivering bi- and tricyclic β-lactones through a Michael-Michael-aldol-β-lactonization. In a single operation, the described multicomponent, organocascade process forms complex bi- and tri-cyclic β-lactones by generating four new bonds, two rings and up to four contiguous stereocenters...

BACKGROUND AND PURPOSE: Recent advances in cancer treatment have resulted in better prognosis with impact on patient's survival, allowing an increase in incidence of a second primary neoplasm. The development of minimally invasive surgery has provided similar outcomes in comparison to open surgery with potentially less morbidity. Consequently, this technique has been used as a safe option to simultaneously treat synchronous abdominal malignancies during a single operating room visit. The objective of this study is to describe the experience of two tertiary cancer hospitals in Brazil, in the minimally invasive treatment of synchronous abdominal neoplasms and to evaluate its feasibility and peri-operative results...

BACKGROUND: Chromosome structure is a very limited model of the genome including the information about its chromosomes such as their linear or circular organization, the order of genes on them, and the DNA strand encoding a gene. Gene lengths, nucleotide composition, and intergenic regions are ignored. Although highly incomplete, such structure can be used in many cases, e.g., to reconstruct phylogeny and evolutionary events, to identify gene synteny, regulatory elements and promoters (considering highly conserved elements), etc...

INTRODUCTION: Right heart catheterization (RHC) is routinely performed to assess hemodynamics. Generally, anticoagulants are held prior to the procedure. At our center, anticoagulants are continued and ultrasound guidance is always used for internal jugular vein access. A micropuncture access kit is used to place a 5 or 6 Fr sheath using the modified Seldinger technique. Manual compression is applied for 10-15 min and the patient is observed for at least 2 hours after the procedure. In a retrospective analysis, we investigated the risk of bleeding complications associated with RHC via the internal jugular vein in patients with and without full anticoagulation...
