To explore if differential pass rates exist in the clinical component of the UK postgraduate clinical psychiatry exam, the Clinical Assessment of Skills and Competencies (CASC), according to ethnicity and place of qualification (UK vs EEA vs overseas graduates).

Observational study using data from the UK Medical Education Database for 2140 doctors sitting the CASC for the first time between 2013 and 2018.

After controlling for age, sex, time of sitting and performance in the written components of the MRCPsych, differences in CASC pass rates persisted between UK graduates self-identifying as Black and Minority Ethnicity (BME) and non-BME (OR for passing 0.36, 95% CI 0.23 to 0.56, p<0.001). Both EEA (OR 0.25, 0.15 to 0.40, p<0.001) and overseas graduates (OR 0.07, 0.05 to 0.11, p<0.001) were less likely to pass the CASC at first attempt, even after controlling for the influence of educational and background variables. These groups, on average, had lower scores on written exams with substantial coitment, training and assessment within psychiatry.The CXCL12 system is central to the development of many organs and is further crucially engaged in pathophysiological processes underlying cancer, inflammation, and cardiovascular disorders. This disease-associated role presently focuses major interest on the two CXCL12 receptors, CXCR4 and atypical chemokine receptor 3 (ACKR3)/CXCR7, as promising therapeutic targets. Major obstacles in these ongoing efforts are confusing reports on the differential use of either ACKR3/CXCR7 and/or CXCR4 across various cells as well as on the specific function(s) of ACKR3/CXCR7. Although basically no doubts remain that CXCR4 represents a classic chemokine receptor, functions assigned to ACKR3/CXCR7 range from those of a strictly silent scavenger receptor eventually modulating CXCR4 signaling to an active and independent signaling receptor. In this review, we depict a thorough analysis of our present knowledge on different modes of organization and functions of the cellular CXCL12 system. We further highlight the potential role of ACKR3/CXCR7 as a "crosslinker" of different receptor systems. Finally, we discuss mechanisms with the potency to impinge on the cellular organization of the CXCL12 system and hence might represent additional future therapeutic targets. SIGNIFICANCE STATEMENT Delineating the recognized functions of atypical chemokine receptor 3 and CXCR4 in CXCL12 signaling is central to the more detailed understanding of the role of the CXCL12 system in health and disease and will help to guide future research efforts.Abscisic acid (ABA), a plant hormone synthesized from carotenoids, functions in seed germination and abiotic stress responses. ABA is derived from the cleavage of 9-cis-isomers of violaxanthin and neoxanthin, which are oxygenated carotenoids, also called xanthophylls. Although genes encoding enzymes responsible for most steps of the ABA biosynthesis pathway have been identified, enzymatic reactions leading to the production of these cis-isomers from trans-violaxanthin remain poorly understood. Two mutants that lack trans- and cis-neoxanthin, tomato (Solanum lycopersicum) neoxanthin-deficient1 (nxd1) and Arabidopsis (Arabidopsis thaliana) ABA-deficient4 (aba4), were identified previously, but only aba4 exhibited ABA-deficient phenotypes. No enzymatic activity was detected for ABA4 and NXD1 proteins, and their exact function remained unknown. To further investigate ABA4 and NXD1 function in Arabidopsis, we compared phenotypes of single and double mutants, and analyzed the effect of ABA4 overexpression on ABA and carotenoid accumulation in wild-type and mutant backgrounds. We provide convergent evidence that ABA4 is not only required for the formation of trans- and 9'-cis-neoxanthin from trans-violaxanthin, but also controls 9-cis-violaxanthin accumulation. While nxd1 produces high amounts of 9-cis-violaxanthin and ABA, aba4 nxd1 exhibits reduced levels in both leaves and seeds. click here Furthermore, ABA4 constitutive expression in nxd1 increases both 9-cis-violaxanthin and ABA accumulation. Subcellular localization of NXD1 protein in transient expression assays suggests that production of the NXD1-derived factor required for neoxanthin synthesis takes place in the cytosol. Finally, we postulate that ABA4, with additional unknown cofactor(s), is required for, or contributes to, trans-to-cis violaxanthin isomerase activity, producing both cis-xanthophyll precursors of ABA.Chromosome level assemblies are accumulating in various taxonomic groups including mosquitoes. However, even in the few reference-quality mosquito assemblies, a significant portion of the heterochromatic regions including telomeres remain unresolved. Here we produce a de novo assembly of the New World malaria mosquito, Anopheles albimanus by integrating Oxford Nanopore sequencing, Illumina, Hi-C and optical mapping. This 172.6 Mbps female assembly, which we call AalbS3, is obtained by scaffolding polished large contigs (contig N50 = 13.7 Mbps) into three chromosomes. All chromosome arms end with telomeric repeats, which is the first in mosquito assemblies and represents a significant step toward the completion of a genome assembly. These telomeres consist of tandem repeats of a novel 30-32 bp Telomeric Repeat Unit (TRU) and are confirmed by analyzing the termini of long reads and through both chromosomal in situ hybridization and a Bal31 sensitivity assay. The AalbS3 assembly included previously uncharacterized centromeric and rDNA clusters and more than doubled the content of transposable elements and other repetitive sequences. This telomere-to-telomere assembly, although still containing gaps, represents a significant step toward resolving biologically important but previously hidden genomic components. The comparison of different scaffolding methods will also inform future efforts to obtain reference-quality genomes for other mosquito species.In many organisms, tissue complexity and cellular diversity create a barrier that can hinder our understanding of gene expression programs. To address this problem, methods have been developed that allow for easy isolation of translated mRNAs from genetically defined cell populations. A prominent example is the Translating Ribosome Affinity Purification method also called TRAP. Here, ribosome associated mRNAs are isolated via purification of the ribosomal protein RPL10A/uL1, which is expressed under the control of a tissue specific promoter. Originally developed to investigate gene expression in mouse neurons, it has by now been adopted to many different organisms and tissues. Interestingly, TRAP has never been used successfully to analyze mRNA translation in germ cells. Employing a combination of genetic and biochemical approaches, I assessed several ribosomal proteins for their suitability for TRAP using the Caenorhabditis elegans germline as a target tissue. Surprisingly, I found that RPL10A/uL1 is not the ideal ribosomal component to perform such an analysis in germ cells. Instead other proteins such as RPL4/uL4 or RPL9/eL6 are much better suited for this task. Tagged variants of these proteins are well expressed in germ cells, integrated into translating ribosomes and do not influence germ cell functions. Furthermore, germ cell-specific mRNAs are much more efficiently co-purified with RPL4/uL4 and RPL9/uL6 compared to RPL10A/uL1. This study provides a solid basis upon which future germ cell TRAP experiments can be built, and it highlights the need for rigorous testing when adopting such methods to a new biological system.

The Royal College of Emergency Medicine highlights poor flow through hospitals as a major challenge to improving emergency department flow. We describe the effect of several hospital-wide flow interventions on Yeovil District Hospital's emergency department flow.

During 2016, a design science research study addressed several areas disproportionally contributing to exit block within Yeovil District Hospital. In this follow-up study, we used a retrospective, before/after design, to describe the effect of these interventions on the ED. We used the Royal College of Emergency Medicine's clinical quality indicators (4-hour standard, time to decision-maker, 7-day unplanned reattendance, left without being seen, ambulatory patient care and patient experience). Pearson correlation coefficient (r) was used to compare variables. Wilcoxon signed-rank test was used to compare performance before and after the intervention.

Yeovil District Hospital emergency department was attended by 160 373 patients between August 2015 and October 2018. Mean monthly attendance was 4112 (±342) patients, mean age was 43 (±28) years with equal male/female split (49/51%). The 4-hour standard made a recovery from 92% to 97% (p=0.01) that did not correlate with a recovery in national data (r=0.09); this despite rising attendances both at Yeovil and nationally (r=0.75). All clinical quality indicators improved significantly (except unplanned reattendance and patient feedback which improved but not significantly).

The positive effect on emergency department clinical quality indicators reveals the beneficial impact of improving in-patient flow. Qualitative research is needed to better understand facilitators and barriers to flow improvement work. .

The cause of death in nearly all cases was compression asphyxia. The clinical and pathological features of deaths encountered in crowds are discussed with a particular focus on the Hillsborough disaster.

Hyperchloraemia is associated with poor clinical outcomes in sepsis patients; however, this association is not well studied for hypochloraemia. We investigated the prevalence of chloride imbalance and the association between hypochloraemia and 28-day mortality in ED patients with septic shock.

A retrospective analysis of data from 11 multicentre EDs in the Republic of Korea prospectively collected from October 2015 to April 2018 was performed. Initial chloride levels were categorised as hypochloraemia, normochloraemia and hyperchloraemia, according to sodium chloride difference adjusted criteria. The primary outcome was 28-day mortality. A multivariate logistic regression model adjusting for age, sex, comorbidities, acid-base state, sepsis-related organ failure assessment (SOFA) score, lactate and albumin level was used to test the association between the three chloride categories and 28-day mortality.

Among 2037 enrolled patients, 394 (19.3%), 1582 (77.7%) and 61 (3.0%) patients had hypochloraemia, normochloraemia and hyperchloraemia, respectively. The unadjusted 28-day mortality rate in patients with hypochloraemia was 27.4% (95% CI, 23.1% to 32.1%), which was higher than in patients with normochloraemia (19.7%; 95% CI, 17.8% to 21.8%). Hypochloraemia was associated with an increase in the risk of 28-day mortality (adjusted OR (aOR), 1.36, 95% CI, 1.00 to 1.83) after adjusting for confounders. However, hyperchloraemia was not associated with 28-day mortality (aOR 1.35, 95% CI, 0.82 to 2.24).

Hypochloraemia was more frequently observed than hyperchloraemia in ED patients with septic shock and it was associated with 28-day mortality.
