Article Synopsis
  • The bioanalytical community traditionally uses blank matrices from preclinical animals for method validation, as required by guidelines, but this practice is increasingly being questioned.
  • Despite scientific support for using surrogate matrices instead, regulatory bodies remain hesitant to accept them for most cases, only allowing them for rare situations.
  • The European Bioanalysis Forum is advocating for the broader acceptance of surrogate matrices, emphasizing ethical considerations and the need for continued discussions, backed by new experimental data.

Article Synopsis
  • The hemojuvelin-hepcidin regulatory axis is crucial for understanding iron metabolism, especially in the context of ischemic stroke (IS).
  • A study involving 45 IS patients measured various iron metabolism biomarkers at two points: on admission and 7 days after the stroke.
  • Results indicated increased ferritin levels and decreased hepcidin levels after 7 days, with significantly higher soluble hemojuvelin levels in patients with specific stroke types and those treated with thrombolysis.

Compared with notifiable disease surveillance, claims-based algorithms estimate higher Lyme disease incidence, but their accuracy is unknown. We applied a previously developed Lyme disease algorithm (diagnosis code plus antimicrobial drug prescription dispensing within 30 days) to an administrative claims database in Massachusetts, USA, to identify a Lyme disease cohort during July 2000-June 2019. Clinicians reviewed and adjudicated medical charts from a cohort subset by using national surveillance case definitions.

Article Synopsis
  • - The study aimed to identify different subpopulations of patients seeking care post-COVID-19 based on their symptoms and resource utilization to improve personalized care and access to specialized services.
  • - Researchers analyzed data from 1,285 COVID-19 patients in Boston, uncovering three distinct clusters, with varying demographics and experiences related to ICU admissions and symptom reporting.
  • - Findings show that patients differ significantly in how they utilize recovery resources, indicating the need for tailored strategies to address the specific needs of these diverse subpopulations for better recovery outcomes.

Objective: Knee osteoarthritis (KOA) is a prevalent disease with a high economic and social cost. Magnetic resonance imaging (MRI) can be used to visualize many KOA-related structures including bone marrow lesions (BMLs), which are associated with OA pain. Several semi-automated software methods have been developed to segment BMLs, using manual, labor-intensive methods, which can be costly for large clinical trials and other studies of KOA.

G protein-coupled receptor 137b (GPR137b) is an orphan seven-pass transmembrane receptor of unknown function. In mouse, Gpr137b is highly expressed in osteoclasts in vivo and is upregulated during in vitro differentiation. To elucidate the role that GPR137b plays in osteoclasts, we tested the effect of GPR137b deficiency on osteoclast maturation and resorbing activity.

This is an account of an interview with David John Hatch who was one of the first Professors of Pediatric Anesthesia in the world. He began his anesthesia career as a medical student administering chloroform and ended it 40 years later as a Consultant at Great Ormond Street Hospital where he developed and led a world renowned research team measuring and assessing lung function in infants and children. These productive years earned him his chair at the Institute of Child Health in London (part of University College London) funded by Portex (currently, a branch of Smiths Medical).

-related muscular dystrophy ( MD or MDC1A) is the most frequent form of early-onset, fatal congenital muscular dystrophies. It is caused by mutations in , the gene encoding laminin-α2, the long arm of the heterotrimeric (α2, β1, and γ1) basement membrane protein laminin-211 (Lm-211). We establish that despite compensatory expression of laminin-α4, giving rise to Lm-411 (α4, β1, and γ1), muscle basement membrane is labile in MD biopsies.

We analysed data from 14,000 patients in the 2013 United Kingdom Anaesthesia Activity Survey of the Fifth National Audit Project of the Royal College of Anaesthetists and Association of Anaesthetists of Great Britain and Ireland to examine anaesthetic, organisational and clinical practice for patients with obesity. We compared practice then with current guidance on management of this patient group. Obesity was reported in 22%, mainly Black, Afro-Caribbean and White Caucasian patients.

Objective: Articular erosions correlate with disability in rheumatoid arthritis (RA). Biologic agents reduce erosion progression in RA, but erosion healing occurs infrequently. This study was undertaken to assess the effects of the anabolic agent teriparatide on joint erosion volume in RA patients treated with a tumor necrosis factor inhibitor (TNFi).

The zebrafish is a powerful experimental model to investigate the genetic and morphologic basis of vertebrate development. Analysis of skeletogenesis in this fish is challenging as a result of the small size of the developing and adult zebrafish. Many of the bones of small fishes such as the zebrafish and medaka are quite thin, precluding many standard assays of bone quality and morphometrics commonly used on bones of larger animals.

MR enterography is the accepted imaging reference standard for small bowel assessment in inflammatory bowel disease. There is an increasing cohort of children with inflammatory bowel disease presenting at an early age (<5 years) with severe disease. Younger children present a technical challenge for enterography because of the need for sedation/general anaesthesia to allow image optimisation and the need for oral contrast to allow adequate luminal assessment.

Objective: Large studies of knee osteoarthritis (KOA) require well-characterized efficient methods to assess progression. We previously developed the local-area cartilage segmentation (LACS) software method, to measure cartilage volume on magnetic resonance imaging (MRI) scans. The present study further validates this method in a larger patient cohort and assesses predictive validity in a case-control study.

This educational review explores the current understanding of accidental awareness during general anesthesia (AAGA) in children. Estimates of incidence in children vary between 1 in 135 (determined by direct questioning) and 1 in 51,500 (determined from spontaneous reporting). The lessons from the 5th National Audit Project of the Royal College of Anaesthetists and the Association of Anaesthetists of Great Britain and Ireland show that the characteristics of spontaneous reports of AAGA are extremely variable and relate to the type of procedure and anesthetic technique rather than age group: approximately 50% of experiences were distressing; most lasted less than 5 min; neuromuscular blockade (NMB) combined with pain caused the most distress; most cases (approximately 70%) occur at induction or emergence.

Background: Single-lung ventilation in infants and small children is challenging because suitable sizes of double-lumen cuffed tracheal tubes are not available. A 6-yr-old child required pulmonary saline washout for primary alveolar proteinosis, and therefore needed sequential single-lung ventilation in order to achieve safe oxygenation. Before undertaking this potentially hazardous procedure, we practised bronchial intubation on an anatomical model of her airway constructed from computed tomography (CT) data.
