Up to 30% of colorectal cancers (CRCs) develop from sessile serrated lesions (SSLs). Within the serrated neoplasia pathway, at least two principally distinct oncogenetic routes exist generating microsatellite-stable and microsatellite-instable CRCs, respectively. Aberrant DNA methylation (DNAm) is found early in the serrated pathway and might play a role in both oncogenetic routes.

Article Synopsis
  • Core outcome sets (COSs) for skin diseases are standardized outcomes that should be measured in clinical trials, and the number of COSs is growing globally, highlighting potential overlaps in concepts.
  • The study aims to conduct a scoping review to categorize and map all outcomes related to COS initiatives for skin diseases, using databases like PubMed and Embase, and involving stakeholder input.
  • The research is funded by the Department of Dermatology at Northwestern University, does not require ethical approval due to the nature of the study, and results will be shared through publications and social media.

Article Synopsis
  • Blood culture contamination (BCC) is linked to longer antibiotic use and healthcare utilization, highlighting the need to reevaluate its impact within the context of antibiotic stewardship.* -
  • A study analyzed data from nearly 23,000 patient admissions across hospitals in the Netherlands and the US, revealing that patients with BCC had significantly more days of antibiotic therapy and additional blood cultures drawn.* -
  • Results indicated that while US patients with BCC experienced higher antibiotic use, Dutch patients faced longer hospital stays; however, mortality rates were similar between both BCC and non-BCC groups.*

Noninvasive scores are poorly predictive of histological fibrosis in paediatric fatty liver disease.

J Pediatr Gastroenterol Nutr

January 2024

Department of Pediatric Gastroenterology, Nephrology and Metabolic Medicine, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität zu Berlin and Humboldt-Universität zu, Berlin, Germany.

Objectives: Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in children. Roughly a quarter of paediatric patients with NAFLD develop nonalcoholic steatohepatitis and fibrosis. Here, we evaluated the diagnostic accuracy of previously published noninvasive fibrosis scores to predict liver fibrosis in a large European cohort of paediatric patients with NAFLD.

Background: Tocilizumab in the treatment of rheumatoid arthritis (RA) is a potential candidate for concentration-guided tapering because the standard dose of tocilizumab results in a wide range of serum concentrations, usually above the presumed therapeutic window, and an exposure-response relationship has been described. However, no clinical trials have been published to date on this subject. Therefore, the objective of this study was to assess the feasibility of the tapering of intravenous (iv) tocilizumab with the use of a pharmacokinetic model-based algorithm in RA patients.

Background: Autoimmune hepatitis (AIH) is a rare, chronic inflammatory disease of the liver. The treatment goal is reaching complete biochemical response (CR), defined as the normalisation of aspartate and alanine aminotransferases and immunoglobulin gamma. Ongoing AIH activity can lead to fibrosis and (decompensated) cirrhosis.

Neurofilament light protein as a biomarker for spinal muscular atrophy: a review and reference ranges.

Clin Chem Lab Med

June 2024

Neurochemistry Laboratory, Department of Laboratory Medicine, Amsterdam Neuroscience, Vrije Universiteit Amsterdam, Amsterdam UMC, Amsterdam, The Netherlands.

Spinal muscular atrophy (SMA) is the leading genetic cause of infant mortality, characterized by progressive neuromuscular degeneration resulting from mutations in the survival motor neuron () gene. The availability of disease-modifying therapies for SMA therapies highlights the pressing need for easily accessible and cost-effective blood biomarkers to monitor treatment response and for better disease management. Additionally, the wide implementation of newborn genetic screening programs in Western countries enables presymptomatic diagnosis of SMA and immediate treatment administration.

Article Synopsis
  • The study aimed to evaluate the diagnostic accuracy of a deep learning AI for detecting cervical spine fractures on CT scans, comparing it to the performance of attending radiologists and identifying fractures requiring stabilizing therapy.
  • A total of 2,368 scans were analyzed, revealing that AI had a sensitivity of 71.5% and detected many fractures missed by radiologists, while radiologists had a higher sensitivity of 88.2% but missed fewer fractures in need of stabilizing therapy.
  • The findings suggest that while the AI missed more fractures overall, it was able to identify some that radiologists missed, including several critical injuries needing intervention.

Background: Recent studies demonstrated that a higher proximal serrated polyp detection rate (PSPDR) among endoscopists is associated with a lower risk of post-colonoscopy colorectal cancer (PCCRC) incidence and death for their patients. Our objective was to evaluate the effect of an e-learning resource on PSPDR.

Methods: We performed a multicenter randomized controlled trial within the Dutch fecal immunochemical test-based colorectal cancer screening program.

Electronic address:

Halofuginone hydrobromide has shown potent antiviral efficacy against a variety of viruses such as SARS-CoV-2, dengue, or chikungunya virus, and has, therefore, been hypothesized to have broad-spectrum antiviral activity. In this paper, we tested this broad-spectrum antiviral activity of Halofuginone hydrobomide against viruses from different families (Picornaviridae, Herpesviridae, Orthomyxoviridae, Coronaviridae, and Flaviviridae). To this end, we used relevant human models of the airway and intestinal epithelium and regionalized neural organoids.

An electrical storm of Torsade de Pointes arrhythmias (TdP) can be reproducibly induced in the anesthetized chronic AV-block (CAVB) dog by infusion of the I-blocker dofetilide. Earlier studies showed that these arrhythmias 1) arise from locations with high spatial dispersion in repolarization (SDR) and 2) can be suppressed by high-rate pacing. We examined whether suppression of TdP by high-rate pacing is established through a decrease in SDR in the CAVB dog.

At present, there are no standardized guidelines for determining patient eligibility for pyoderma gangrenosum (PG) clinical trials. Thus, we aim to determine which clinical features, histopathological features, or laboratory features should be included in active ulcerative PG clinical trial eligibility criteria for treatment-naïve patients and patients already treated with immunomodulating medications (treatment-exposed patients). This study employed 4 rounds of the Delphi technique.

  • Teclistamab, a bispecific antibody targeting BCMA, shows strong effectiveness in patients with multiple myeloma but leads to a high incidence of infections due to its impact on the immune system.
  • The treatment results in rapid depletion of B cells and significantly lowers levels of various immunoglobulins, impairing patients' ability to respond to vaccines.
  • Utilizing intravenous immunoglobulin (IVIG) can reduce the risk of serious infections in patients on teclistamab, highlighting the importance of immunoglobulin support in managing these patients' immune health.
