Background Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) affects about a third of adults worldwide and is projected soon to be the leading cause of cirrhosis. It occurs when fat accumulates in hepatocytes and can progress to metabolic dysfunction-associated steatohepatitis (MASH), liver cirrhosis, and hepatocellular carcinoma. MASLD pathogenesis is believed to involve a combination of genetic and environmental risk factors.

Article Synopsis
  • Primary ciliary dyskinesia (PCD) is a rare genetic disorder linked to chronic respiratory issues, infertility, and problems with body asymmetry, primarily caused by mutations in the CCDC39 and CCDC40 genes.
  • Researchers used advanced techniques to investigate how these genetic variants impact cellular functions beyond just causing cilia to stop moving.
  • They discovered that the absence of CCDC39/CCDC40 creates a significant loss of over 90 ciliary structural proteins, leading to cilia dysfunction and other cellular issues, suggesting that gene therapy could potentially offer a new treatment strategy for PCD.

Background: The treatment of status epilepticus (SE) in children with cardiac disease is challenging given their often-tenuous hemodynamic state. We aim to determine whether ketamine is safe and effective in children with cardiac disease as the first-line continuous infusion for the treatment of refractory SE (RSE) and to compare ketamine to midazolam for the treatment of RSE in this population.

Methods: This is a single-center retrospective cohort study of pediatric patients with cardiac disease and RSE admitted to the cardiac intensive care unit at a tertiary children's hospital between January 1, 2017 and June 30, 2023.

Classical tissue recombination experiments demonstrate that cell-fate determination along the anterior-posterior axis of the Müllerian duct occurs prior to postnatal day 7 in mice. However, little is known about how these cell types are maintained in adults. In this study, we provide genetic evidence that a balance between antagonistic retinoic acid (RA) and estrogen signaling activity is required to maintain simple columnar cell fate in adult uterine epithelium.

Because of the crucial role of the menisci in maintaining cartilage and joint health, meniscal tears affect the long-term health of the knee. Although partial meniscectomy has a role in the treatment of complex degenerative tears and tears with low healing capacity, advances in the concepts and understanding of meniscal repair, along with improvements in repair techniques and instrumentation, have expanded the indications for meniscal repair. With appropriate patient selection and preoperative planning, repair of meniscal tears can lower the rate of degenerative changes when compared with meniscectomy.

Nebulized aminoglycosides for ventilator-associated pneumonia: Methodological considerations and lessons from experimental studies.

J Intensive Med

January 2025

Department of Pneumology, Institut Clinic del Tórax, Hospital Clinic of Barcelona - Institut d'Investigacions Biomèdiques August Pi i Sunyer (IDIBAPS), University of Barcelona - SGR 911- Ciber de Enfermedades Respiratorias (Ciberes), Barcelona, Spain.

Aminoglycosides are concentration-dependent antibiotics exerting a bactericidal effect when concentrations at the site of infection are equal to or greater than 5 times the minimum inhibitory concentrations (MIC). When administered intravenously, they exhibit poor lung penetration and high systemic renal and ototoxicity, imposing to restrict their administration to 5 days. Experimental studies conducted in anesthetized and mechanically ventilated sheep and pigs provide evidence that high doses of nebulized aminoglycosides induce a rapid and potent bacterial killing in the infected lung parenchyma.

Rome Foundation Working Team Report on overlap in disorders of gut-brain interaction.

Nat Rev Gastroenterol Hepatol

January 2025

Department of Molecular and Clinical Medicine, Institute of Medicine, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden.

In patients with disorders of gut-brain interaction (DGBI), overlapping non-gastrointestinal conditions such as fibromyalgia, headaches, gynaecological and urological conditions, sleep disturbances and fatigue are common, as is overlap among DGBI in different regions of the gastrointestinal tract. These overlaps strongly influence patient management and outcome. Shared pathophysiology could explain this scenario, but details are not fully understood.

The somato-cognitive action network (SCAN) consists of three nodes interspersed within Penfield's motor effector regions. The configuration of the somato-cognitive action network nodes resembles the one of the 'plis de passage' of the central sulcus: small gyri bridging the precentral and postcentral gyri. Thus, we hypothesize that these may provide a structural substrate of the somato-cognitive action network.

methylGrapher: genome-graph-based processing of DNA methylation data from whole genome bisulfite sequencing.

Nucleic Acids Res

January 2025

Department of Genetics, The Edison Family Center for Genome Sciences & Systems Biology, Washington University School of Medicine, St. Louis, MO 63110, USA.

Genome graphs, including the recently released draft human pangenome graph, can represent the breadth of genetic diversity and thus transcend the limits of traditional linear reference genomes. However, there are no genome-graph-compatible tools for analyzing whole genome bisulfite sequencing (WGBS) data. To close this gap, we introduce methylGrapher, a tool tailored for accurate DNA methylation analysis by mapping WGBS data to a genome graph.

ATG-3 limits Orsay virus infection in through regulation of collagen pathways.

bioRxiv

January 2025

Division of Infectious Diseases, Department of Medicine, Edison Family Center for Genome Sciences & Systems Biology, Washington University School of Medicine, St. Louis, MO, USA.

Autophagy is an essential cellular process which functions to maintain homeostasis in response to stressors such as starvation or infection. Here, we report that a subset of autophagy factors including ATG-3 play an antiviral role in Orsay virus infection of . Orsay virus infection does not modulate autophagic flux, and re-feeding after starvation limits Orsay virus infection and blocks autophagic flux, suggesting that the role of ATG-3 in Orsay virus susceptibility is independent of its role in maintaining autophagic flux.
