Article Synopsis
  • The study explores fetal and offspring heart adaptations in cases of fetal growth restriction (FGR) compared to healthy controls over time.
  • Using advanced echocardiographic techniques, researchers found significant differences in heart geometry and function between FGR and healthy fetuses, including increased cardiac output and impaired diastolic function in FGR cases.
  • Findings suggest that changes in heart structure and function associated with FGR may be linked to chronic lack of oxygen from the placenta, potentially leading to long-term cardiovascular issues in affected children.

In recent years, the use of 2-benzylbenzimidazole opioids ('nitazenes') has increased with them becoming one of the most prominent synthetic opioid subclasses of novel psychoactive substances. With the increased prevalence, there is also a concern of the dangers to public health with the use of nitazenes due to their high potency especially with polypharmacy. To aid in the detection of such compounds, it is important that forensic toxicology laboratories maintain up-to-date compound libraries for drug screening methods and that sensitive analytical instrumentation is available to detect the low blood/plasma concentrations of more potent drugs.

Defining accurate terminology for post-injury weightbearing instructions.

Bone Joint J

July 2024

Oxford Trauma and Emergency Care, Kadoorie Centre, John Radcliffe Hospital, Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Science, University of Oxford, Oxford, UK.

Aims: Weightbearing instructions after musculoskeletal injury or orthopaedic surgery are a key aspect of the rehabilitation pathway and prescription. The terminology used to describe the weightbearing status of the patient is variable; many different terms are used, and there is recognition and evidence that the lack of standardized terminology contributes to confusion in practice.

Methods: A consensus exercise was conducted involving all the major stakeholders in the patient journey for those with musculoskeletal injury.

Collagen IV deficiency causes hypertrophic remodeling and endothelium-dependent hyperpolarization in small vessel disease with intracerebral hemorrhage.

EBioMedicine

September 2024

School of Cardiovascular and Metabolic Health, College of Medical Veterinary and Life Sciences, University of Glasgow, Glasgow G12 8QQ, UK. Electronic address:

Background: Genetic variants in COL4A1 and COL4A2 (encoding collagen IV alpha chain 1/2) occur in genetic and sporadic forms of cerebral small vessel disease (CSVD), a leading cause of stroke, dementia and intracerebral haemorrhage (ICH). However, the molecular mechanisms of CSVD with ICH and COL4A1/COL4A2 variants remain obscure.

Methods: Vascular function and molecular investigations in mice with a Col4a1 missense mutation and heterozygous Col4a2 knock-out mice were combined with analysis of human brain endothelial cells harboring COL4A1/COL4A2 mutations, and brain tissue of patients with sporadic CSVD with ICH.

Since the 1960s, cardiologists have adopted several binary classification systems for acute myocardial infarction (MI) that facilitated improved patient management. Conversely, for chronic stable manifestations of myocardial ischemia, various classifications have emerged over time, often with conflicting terminology-eg, "stable coronary artery disease" (CAD), "stable ischemic heart disease," and "chronic coronary syndromes" (CCS). While the 2019 European guidelines introduced CCS to impart symmetry with "acute coronary syndromes" (ACS), the 2023 American guidelines endorsed the alternative term "chronic coronary disease.
