Special screw corridors and imaging in pelvic ring trauma.

Adequate intraoperative visualization is mandatory for implant application in pelvic ring injuries. Several fluoroscopic X-ray views are in practical use. The gold standard primary X-ray is the anteroposterior view of the pelvis.

Host hepatocyte senescence determines the success of hepatocyte transplantation in a mouse model of liver injury.

Background & Aims: Hepatocyte transplantation has shown promise for genetic diseases of the hepatocytes but to date has shown limited efficacy for non-genetic forms of severe liver injury. Limited cell engraftment and poor function of donor hepatocytes in recipient livers impacts the clinical utility of hepatocyte cell therapy. The mechanisms underpinning this are poorly understood.

Nonhuman primate antigenic cartography of SARS-CoV-2.

Virus neutralization profiles against primary infection sera and corresponding antigenic cartography are integral part of the COVID-19 and influenza vaccine strain selection processes. Human single variant exposure sera have previously defined the antigenic relationships among SARS-CoV-2 variants but are now largely unavailable due to widespread population immunity. Therefore, antigenic characterization of future SARS-CoV-2 variants will require an animal model, analogous to using ferrets for influenza virus.

Behind the scenes of EQA - characteristics, capabilities, benefits and assets of external quality assessment (EQA).

This is the first in a series of five papers that detail the role and substantial impact that external quality assessment (EQA) and their providers' services play in ensuring diagnostic (IVD) performance quality. The aim is to give readers and users of EQA services an insight into the processes in EQA, explain to them what happens before EQA samples are delivered and after examination results are submitted to the provider, how they are assessed, what benefits participants can expect, but also who are stakeholders other than participants and what significance do EQA data and assessment results have for them. This first paper presents the history of EQA, insights into legal, financing and ethical matters, information technology used in EQA, structure and lifecycle of EQA programs, frequency and intensity of challenges, and unique requirements of extra-examination and educational EQA programs.

Behind the scenes of EQA - characteristics, capabilities, benefits and assets of external quality assessment (EQA).

External quality assessment (EQA) cycles are the smallest complete units within EQA programs that laboratories can use to obtain external assessments of their performance. In each cycle, several samples are distributed to the laboratories registered for participation, and ideally, EQA programs not only cover the examination procedures but also the pre- and post-examination procedures. The properties and concentration range of measurands in individual samples are selected with regard to the intended challenge for the participants so that each sample fulfils its purpose.

Behind the scenes of EQA - characteristics, capabilities, benefits and assets of external quality assessment (EQA).

External quality assessment (EQA) enhances patient safety through the evaluation of the quality of laboratory-based and point of care testing. Regulatory agencies and accreditation organizations utilize the results and the laboratory's response to them as part of assessing the laboratory's fitness to practice. In addition, where EQA samples are commutable and the assigned value has been determined using reference measurement procedures (RMPs), EQA data contributes to the verification of metrological traceability of assays as part of the post-market surveillance of diagnostic (IVD) medical devices (IVD-MDs).

Behind the scenes of EQA - characteristics, capabilities, benefits and assets of external quality assessment (EQA).

Providers of external quality assessment (EQA) programs evaluate data or information obtained and reported by participant laboratories using their routine procedures to examine properties or measurands in samples provided for this purpose. EQA samples must offer participants an equal chance to obtain accurate results, while being designed to provide results in clinically relevant ranges. It is the responsibility of the EQA provider to meet the necessary requirements for homogeneity, stability and some other properties of the EQA items in order to offer participants a fair, reliable and technically interesting EQA experience.

Posterolateral Knee Ligament Reconstruction Using the Arciero Technique Provides Greater Rotational Stability Than the Modified Larson Technique: A Biomechanical Study.

Background: It is still unknown if the double-femoral tunnel technique (Arciero [ARC]) provides better stability as compared with the single-femoral tunnel technique (modified Larson [LAR]) in posterolateral corner reconstruction. The ideal angle of fixation of the popliteofibular strand in ARC is also unknown.

Hypotheses: The ARC provides greater external rotation (ER) stability than the LAR (hypothesis 1); there is no difference in varus rotation (VR) stability between LAR and ARC (hypothesis 2); and femoral fixation of the popliteofibular strand at 60° during the ARC leads to greater ER stability than fixation at 30° or 90° of knee flexion (hypothesis 3).

Improving small-scale cultivation of Spodoptera frugiperda 9 cells by silanizing glassware.

Cultivating insect cells in glass vessels can be challenging. Due to uncontrolled cell adhesion and associated cell loss as well as clumping, the replication of experiments is put at risk. A cost-effective solution to improve and stabilize cultivation may be to silanize glass vessels, making them more hydrophobic and chemically inert.

Investigation of the Urinary Peptidome to Unravel Collagen Degradation in Health and Kidney Disease.

Naturally occurring fragments of collagen type I alpha 1 chain (COL1A1) have been previously associated with chronic kidney disease (CKD), with some fragments showing positive and others negative associations. Using urinary peptidome data from healthy individuals (n = 1131) and CKD patients (n = 5585) this aspect was investigated in detail. Based on the hypothesis that many collagen peptides are derived not from the full, mature collagen molecule, but from (larger) collagen degradation products, relationships between COL1A1 peptides containing identical sequences were investigated, with the smaller (offspring) peptide being a possible degradation product of the larger (parent) one.

Perinatal and infant mental health care in Austria : Mapping of existing prevention, screening, and care services.
