Safety incident reporting is essential in medical imaging (MI) departments due to the fast-paced environment and high patient volume. However, there is an evident knowledge gap in the identification and investigation of contributing factors to incidents reports in MI departments. The objective of this study was to investigate the following rates of incident reporting in a MI department at a large academic health sciences centre departmental incident rate, incident rates per imaging modality, and incident rates per incident type. Characteristics associated with the most frequently occurring incident types were examined to identify opportunities for quality improvement.

This observational, retrospective study collected approximately 665 MI incident reports submitted by staff between July 2018 and July 2019. Individual incident reports were categorized according to imaging modality and incident type. Subcategories of the top four incident types were also created to identify possible contributory factors baseincreased use of drop-down menus to capture more open-ended responses, corrective strategies can be implemented to address safety concerns in MI departments. Doxycycline solubility dmso In comparison to incident reporting rates published in similar studies, there may be a significant underrepresentation of safety incident reports filed from underreporting. Reducing barriers to reporting is essential in improving the effectiveness of the current safety incident reporting system.
Patients with chronic kidney disease (CKD) are at high risk of cardiovascular morbidity and mortality. Subclinical cardiac structural alterations have prognostic value in these patients. The aim was to analyse the prevalence of valvular calcification, the evolution and the relationship with different risk factors.

Part of the sample of the NEFRONA study was randomly selected. Aortic and mitral valve calcification were analysed in echocardiograms performed at the baseline visit and at 24 months.

We included 397 patients, the estimated basal glomerular filtrate (eGFR) was 33ml/min with significant decrease to 30.9ml/min. There was an increase in the area of carotid and femoral plaque, as well as an increase in patients with aortic and mitral calcification at 24 months. A positive association of mitral calcification at 24 months with age, ankle-brachial index (ABI) and calcium-phosphorus product (CaxP) at baseline visit was observed, without association with eGFR. Aortic calcification at 24 months was posih older age, higher phosphorous levels and larger area of carotid plaque. Identifying these higher risk patients would help to avoid future cardiovascular events intensifying follow-ups.Azithromycin is a macrolide antibiotic which is used to treat a wide variety of bacterial infections. Impurity P is one of the impurities in azithromycin product, which is registered in Pharmacopoeias of Europe and USA. However, to date, the structure of this impurity has still not been elucidated. In this work, we separated impurity P from azithromycin product using preparative chromatography and successfully identified its chemical structure using multiple analytical techniques. First, high-resolution ion trap-time-of-flight mass spectrometry (IT-TOF MS) was used to determine the accurate molecular mass ([M+H]+m/z 777.5121) and the chemical formula (C39H72N2O13) of the impurity. Second, Fourier transforming infrared spectroscopy (FT-IR), ultraviolet-visible absorption spectroscopy (UV-vis) and tandem mass spectrometry (MS/MS) analyses were performed to probe into the key functional groups of the impurity to aid the NMR analysis. Finally, the structure of the impurity was successfully resolved using multidimensional NMR. In addition, a mechanism for the formation of this impurity was proposed.Curcumae Rhizoma (CR) and vinegar processed Curcumae Rhizoma (PCR) are common medicinal materials widely used in clinical practice in China. There are sliced CR (SCR) and two kinds of PCR products which are processed by different methods WPCR-prepared with the whole CR root boiled in vinegar and then sliced, and SPCR-prepared with the whole CR root steamed and sliced before boiled with vinegar. In this study, the feasibility of Fourier transform near infrared spectrum (FT-NIR) used to determine the main discrepant components of SCR, WPCR and SPCR were investigated. High performance liquid chromatography (HPLC) was used to identified five discrepant compounds in the three kinds of CR products-curzerene, curcumenol, curdione, furanodienone and demethoxycurin. Pretreatment of NIR qualitative data by different methods revealed that the second derivative in combination with 9 points of Savitzky-Golay smooth (2D9S) could accurately distinguish SCR, SPCR and WPCR from each other, and the discrimination ability was i concluded that the NIR system, combined with appropriate variable selection and linear regression method, can precisely distinguish SCR, SPCR and WPCR from each other, and can accurately and rapidly determine the four discrepant compounds in the three CR products, suggesting a potential of being routinely used for a more diversified analysis in medicinal herbs study.DNA machines are smart artificial devices that perform well-organized DNA hybridization reactions or nanoscale mechanical movements. Herein, a nanoscale assembly line composing of dual DNA machines is meticulously designed by coupling a catalytic hairpin assembly (CHA)-based machine with a 3D DNA walker machine. Equipped with upconversion nanoparticles (UCNPs) as signal tags, the dual DNA machines-based assembly line (DDMAL) can efficiently amplify the fluorescent signal of target recognition event, enabling sensitive detection of microRNA (miRNA). In detail, once activated by target miRNA-21, the CHA machine is initiated to constantly produce a single-stranded DNA (named binding DNA) via the strand displacement reaction. The binding DNA as a trigger factor can initiate the DNA walker machine by linking a walking strand DNA with an anchor strand DNA immobilized on the surface of magnetic beads (MBs). The movement of walking strand on the surface of MBs is then driven by Mn2+-dependent DNAzyme formed through the hybridization of walking strand with a UCNPs-linked substrate strand.
