Background/Aims This study aimed to determine the risk of post-endoscopic retrograde cholangiopancreatography (post-ERCP) bleeding among patients taking antiplatelet agents (APAs), particularly in the era of multiple APAs. Methods The primary outcomes were the frequency, type, and severity of ERCP-related bleeding according to the use of APAs. Results The frequencies of post-ERCP bleeding a...
This study analysed PCB-contaminated natural soil excavated from an area adjacent to an electrical transformer station in Zadar, Croatia. For one year, PCB concentrations were measured in the soil and leachate water under natural climatic conditions. After 12 months, a negligible quantity of Aroclor 1248 (0.024% in average) and a total of seven key PCB congeners (IUPAC No: PCB-28, PCB-52, PCB-1...
Endoscopic variceal band ligation (EVL) is an effective procedure to control and prevent variceal bleeding in patients with liver cirrhosis, but it can be complicated by bleeding from post-EVL ulcers. Several studies have reported that proton pump inhibitors (PPIs) decrease the size of post-EVL ulcers. However, evidence are limited as to whether PPIs actually reduce the risk of bleeding after E...
Introduction: Tonsillectomy is one of the most common procedures performed by Ear, Nose, and Throat surgeon. Usually, the procedure is carried out as an inpatient surgery. With the increasing need to reduce healthcare costs, spare precious hospital beds, and shorten elective surgery lists, there is currently a trend towards performing tonsillectomy on a daycare basis. Materials and Methods: A...
We analyzed residual PCBs in surface sediments at 19 sites in the Pearl River Delta in the wet and dry seasons. Seven indicative PCB congeners (PCB28, PCB52, PCB101, PCB118, PCB153, PCB138 and PCB180) were detected in the surface sediments, among which the detection rate and mass concentrations of PCB52 were the highest. Total concentrations of the seven PCBs ranged from 19.8 to 111 μg/kg, with...
BACKGROUND Bleeding after polypectomy is a common issue associated with colonoscopy. To help prevent post-polypectomy bleeding, many endoscopists place clips at the site. However, this practice remains controversial. Therefore, we performed a meta-analysis of the efficacy of clip placement in the prevention of post-polypectomy bleeding. METHODS Multiple databases, including Embase, Scopus, ME...
BACKGROUND It has been suggested that pre- and postnatal exposure to persistent organic pollutants (POPs) can promote several adverse effects in children, such as altered neurodevelopment. Epidemiologic studies to date have relied on the analysis of biological samples drawn pre- or post-natally for exposure assessment, an approach that might not capture some key events in the toxicokinetics of ...
circularly-polarized antenna is built based on a new siw (substrate integrated waveguide)structure which contains cavity-backed resonator and a conventional polarized ring with twosquare slits in inner and outer ring that differ 90° at position and is proposed for right-handedcircular polarization (rhcp) and fabricated in two separate layers. a broadband impedancebandwidth of 13.9% and a rhcp a...
