Speckle tracking echocardiography and cardiac magnetic resonance (CMR) are also gaining attention as important tools for the assessment of RV structure, fibre deformation and systolic performance. Further research is needed to confirm the utility and prognostic significance of RV [18F]fluorodeoxyglucose (FDG) positron emission tomography imaging as FDG accumulation is suggested to increase with progressive RVD. Targeted pharmacotherapy with phosphodiesterase inhibitors, guanylate-cyclase stimulators, nitrates and inhaled inorganic nitrites have yet to demonstrate improvement in RVD, compelling the need for evaluation and discovery of novel pharmacological interventions for this entity.Several genes associated with hereditary ovarian cancer have been discovered as a result of the work done with next generation sequencing. It is estimated that approximately 23% of ovarian carcinomas have a hereditary predisposition. The most common hereditary condition is represented by germline mutations in BRCA1 or BRCA2 genes that account for 20-25% of high grade serous ovarian cancer. A number of other hereditary ovarian cancers are associated with different genes, with a crucial role in the DNA damage response pathway, such as the mismatch repair genes in Lynch syndrome, TP53 in Li-Fraumeni syndrome, STK11 in Peutz-Jeghers syndrome, CHEK2, RAD51, BRIP1, and PALB2. The goal of this manuscript is to summarize the published data regarding the molecular pathways involved in the pathogenesis of non-BRCA related hereditary ovarian cancer and to provide a tool that might be useful in discussing risk assessment, genetic testing, prevention strategies, as well as clinical and therapeutic implications for patients with ovarian cancer.Abigail McGlennon of the Animal Health Trust and Andrea Vilela of the Redwings Horse Sanctuary describe the creation and impact of a new initiative to tackle strangles in UK horses.

Next Generation Sequencing (NGS)-based

tumour tissue testing poses several challenges. As a first step of its implementation within a regional health service network, an in-house validation study was compared with published recommendations.

Epithelial ovarian cancer (EOC) formalin-fixed paraffin-embedded specimens stored in the archives of the eight regional pathology units were selected from a consecutive series of patients with known

germline status. Two expert pathologists evaluated tumour cell content for manual macrodissection. DNA extraction, library preparation and NGS analyses were performed blinded to the germinal status. Parameters used in the study were confronted with guidelines for the validation of NGS-based oncology panels and for

tumour tissue testing.

NGS analyses were successful in 66 of 67 EOC specimens, with good quality metrics and high reproducibility among different runs. In all, 19

pathogenic variants were identified 12 were germline and 7 were somatic. A 100% concordance with blood tests was detected for germline variants. A

variant showed a controversial classification. ABT-199 Bcl-2 inhibitor In different areas of two early stage EOCs showing somatic variants, intratumour heterogeneity not relevant for test results (variant allele frequency >5%) was observed. Compared with expert recommendations, main limitations of the study were absence of controls with known somatic

status and exclusion from the validation of

copy number variations (CNV).

A close collaboration between pathology and genetics units provides advantages in the implementation of

tumour tissue testing. The development of tools for designing and interpreting complex testing in-house validation could improve process quality.

Individualized prediction of mortality risk can inform the treatment strategy for patients with COVID-19 and solid tumors and potentially improve patient outcomes. We aimed to develop a nomogram for predicting in-hospital mortality of patients with COVID-19 with solid tumors.

We enrolled patients with COVID-19 with solid tumors admitted to 32 hospitals in China between December 17, 2020, and March 18, 2020. A multivariate logistic regression model was constructed via stepwise regression analysis, and a nomogram was subsequently developed based on the fitted multivariate logistic regression model. Discrimination and calibration of the nomogram were evaluated by estimating the area under the receiver operator characteristic curve (AUC) for the model and by bootstrap resampling, a Hosmer-Lemeshow test, and visual inspection of the calibration curve.

There were 216 patients with COVID-19 with solid tumors included in the present study, of whom 37 (17%) died and the other 179 all recovered from COVID-19 and months before COVID-19 diagnosis, elevated WBC count and dNLR, and having dyspnea on admission were independent risk factors for mortality among patients with COVID-19 and solid tumors. The nomogram based on these factors accurately predicted mortality risk for individual patients.

Increasing age, receipt of antitumor treatment within 3 months before COVID-19 diagnosis, elevated WBC count and dNLR, and having dyspnea on admission were independent risk factors for mortality among patients with COVID-19 and solid tumors. The nomogram based on these factors accurately predicted mortality risk for individual patients.Lung ultrasound has been described for over a decade and international protocols exist for its application. It is a controversial area among pulmonologists and has had more uptake with emergency as well as intensive care physicians. We discuss the basics and evidence behind the use of lung ultrasound in respiratory failure, and what role we see it playing in the current 2019 novel coronavirus pandemic.Innocuous mechanical stimuli, such as rubbing or stroking the skin, relieve itch through the activation of low-threshold mechanoreceptors. However, the mechanisms behind this inhibition remain unknown. We presently investigated whether stroking the skin reduces the responses of superficial dorsal horn neurons to pruritogens in male C57BL/6J mice. Single-unit recordings revealed that neuronal responses to chloroquine were enhanced during skin stroking, and this was followed by suppression of firing below baseline levels after the termination of stroking. Most of these neurons additionally responded to capsaicin. Stroking did not suppress neuronal responses to capsaicin, indicating state-dependent inhibition. Vesicular glutamate transporter 3 (VGLUT3)-lineage sensory nerves compose a subset of low-threshold mechanoreceptors. Stroking-related inhibition of neuronal responses to chloroquine was diminished by optogenetic inhibition of VGLUT3-lineage sensory nerves in male and female Vglut3-cre/NpHR-EYFP mice. Conversely, in male and female Vglut3-cre/ChR2-EYFP mice, optogenetic stimulation of VGLUT3-lineage sensory nerves inhibited firing responses of spinal neurons to pruritogens after the termination of stimulation.
