BACKGROUND: The presence of an abdominal seatbelt sign (ASBS) following a motor vehicle collision (MVC) is associated with a high risk for occult intraabdominal injury, prompting imaging studies and a prolonged period of clinical observation. The aim of this study was to determine how a negative computerized tomography (CT) of the abdomen/pelvis (A/P) can serve in the safe disposition of these patients. Our hypothesis was that in the setting of a negative CT, the presence of occult intra-abdominal injuries requiring a delayed intervention is extremely unlikely...

Few studies have evaluated the relationships between intake of sugar-sweetened beverages (SSB) and intermediate biomarkers of cardiometabolic risk. Associations between artificially sweetened beverages (ASB) and fruit juice with cardiometabolic biomarkers are also unclear. We investigated habitual SSB, ASB and fruit juice intake in relation to biomarkers of hepatic function, lipid metabolism, inflammation and glucose metabolism. We analysed cross-sectional data from 8492 participants in the Nurses' Health Study who were free of diabetes and CVD...

We present a new approach to arsenic (As) risk assessment using biomonitoring. In this pilot study we determined the levels of total and speciated urinary arsenicin 109 Spanish school children aged between 6 and 11 years, and interpreted these concentrations in a risk assessment context. The geometric mean (GM) for total As (TAs) was 33.82 μ/L. The order of occurrence and average concentrations of the different species was arsenobetaine (AsB) (100%, 15 μg/L), dimethylarsinic (DMA) (97%, 8.32 μg/L), monomethylarsonic (MMA) (26%, 0...

Condensation of benzene-1,3,5-tricarbohydrazide with benzene-1,4-dicarboxaldehyde generated a new covalent organic framework, COF-ASB (1), in which the organic units are held together via hydrazone linkage to form porous frameworks. COF-ASB (1) is highly crystalline and displays good chemical and thermal stability and is permanently porous. In addition, 1 can be an ideal support to load Ru nanoparticles (Ru NPs) to generate Ru@COF-ASB (2). The obtained composite material is able to highly promote one-pot tandem synthesis of imine products from benzyl alcohols and corresponding amines under solvent-free conditions in air...

Qualitative 2D gel-electrophoresis (2DE) protein profiling for osteoarthritis (OA) and rheumatoid arthritis (RA) is challenging because of selective protein loss due to discrepancies in protein precipitation methodologies. Thus, we aimed at developing qualitative proteinrepresentation from OA/RA articular cartilage without protein precipitation towards identification of clinically relevant proteins. Chondroitinase digested human articular cartilages from RA patients were subjected to protein extraction using guanidinium hydrochloride (GuHCl) or 8 M urea with 10 or 2% ASB-14-4 or 0...

Background -Heart failure (HF) is a leading cause of mortality and morbidity, and the search for novel therapeutic approaches continues. In the monogenic disease mucopolysaccharidosis (MPS) VI, loss of function mutations in arylsulfatase B (ASB) leads to myocardial accumulation of chondroitin sulfate (CS) glycosaminoglycans (GAGs), manifesting as a myriad of cardiac symptoms. Here, we studied changes in myocardial CS in non-MPS failing hearts, and assessed its generic role in pathological cardiac remodeling...

BACKGROUND: Many orthopaedic surgeons worry about asymptomatic bacteriuria (ASB) as a possible risk factor for prosthetic joint infection (PJI). However, available evidence establishing a direct link between ASB and PJI is limited. This meta-analysis aimed to investigate whether ASB is a factor for PJI and whether pre-operative antibiotic treatment shows benefit. METHOD: We systematically searched major databases such as PubMed, Web of Science, the Cochrane Library and EMBASE for studies...

The total arsenic (As) and As species were analyzed in 19 species of wild marine organisms collected from 12 locations in Daya Bay, China; additionally, both the levels of As in the seawater and sediments and the salinity were investigated. The greatest level of As was found in crabs (13.4-35.1 μg/g), followed by shrimps (8.52-27.6 μg/g), benthic fish (3.45-28.6 μg/g), and pelagic fish (1.22-5.23 μg/g). There were significantly positive correlations between the As concentrations in the benthic fish Callionymus richardsonii/shrimp Metapenaeopsis palmensis and those in sediments, indicating that As levels in them were highly dependent on those in the sediments...

BACKGROUND: Antimicrobial stewardship to combat the spread of antibiotic-resistant bacteria has become a national priority. This project focuses on reducing inappropriate use of antimicrobials for asymptomatic bacteriuria (ASB), a very common condition that leads to antimicrobial overuse in acute and long-term care. We previously conducted a successful intervention, entitled "Kicking Catheter Associated Urinary Tract Infection (CAUTI): the No Knee-Jerk Antibiotics Campaign," to decrease guideline-discordant ordering of urine cultures and antibiotics for ASB...

BACKGROUND: Low resting heart rate (RHR) is a consistent biological correlate of antisocial behaviour (ASB), however potential mechanisms have been largely unexplored. We hypothesise that lower RHR will be associated with higher ASB levels in mid-adolescence and persistence into adulthood, and that these associations will be explained, in part, by sensation seeking and callous-unemotional traits. METHODS: ASB was assessed repeatedly with young people from ages 15 to 21 years in a population-based birth cohort (ALSPAC)...
