We assessed the diagnostic performance of the Narrow-Band Imaging (NBI) International Colorectal Endoscopic Classification (NICE) and the Japan NBI Expert Team classification (JNET) in predicting histological outcomes of advanced colorectal lesions. Additionally, we evaluated the sensitivity and positive predictive value (PPV) of the JNET and NICE classifications individually for high-grade lesions (including HGD adenomas, intramucosal carcinomas, and T1 carcinomas). This was a retrospective analysis of prospectively collected data, involving 211 patients (130 men, mean age 60 years) who underwent colonoscopy with endoscopic resection of advanced colorectal neoplasia (lesions ≥ 10 mm).

Proto-oncogene KRAS, GTPase (KRAS) is one of the most intensively studied oncogenes in cancer research. Although several mouse models allow for regulated expression of mutant KRAS, selective isolation and analysis of transforming or tumor cells that produce the KRAS oncogene remains a challenge. In our study, we present a knock-in model of oncogenic variant KRAS that enables the "activation" of KRAS expression together with production of red fluorescent protein tdTomato.

Newborn screening for SCID and severe T lymphocytopenia in Europe.

J Allergy Clin Immunol

November 2024

Laboratory for Paediatric Immunology, Willem-Alexander Children's Hospital, Leiden University Medical Center, Leiden, The Netherlands. Electronic address:

Article Synopsis
  • Newborn screening (NBS) programs in Europe started in the 1960s, expanding recently to include testing for severe combined immunodeficiency (SCID) through T-cell receptor excision circles (TRECs).
  • A survey sent to 46 European countries collected comprehensive data, with 38 countries responding, revealing that 17 have already implemented TREC-based NBS.
  • The findings indicate a need to reassess the definition of the target disease to include conditions beyond SCID and highlight the importance of international collaboration for improving universal TREC-based screening.

Article Synopsis
  • Albendazole has limited effectiveness against Echinococcosis, prompting research into improving treatment outcomes, particularly through the use of Sulfonated Graphene Oxide (S-GO) as a nanocarrier.
  • In the study, protoscoleces were treated with different agents, and it was found that S-GO combined with Albendazole (S-GO-Albendazole) enhanced gene expression and was 18% more effective at reducing the survival of protoscoleces compared to Albendazole alone.
  • Despite S-GO's lack of strong lethality on its own, it significantly improved Albendazole's efficacy, suggesting its potential as a nanocarrier, but further studies are necessary to assess

J Allergy Clin Immunol

December 2024

Department of Immunology and Gene Therapy, Great Ormond Street Hospital for Children NHS Foundation Trust, London, United Kingdom; Infection Immunity and Inflammation Research and Teaching Department, University College London Great Ormond Street Institute of Child Health, London, United Kingdom.

Article Synopsis
  • Congenital athymia is a serious condition that affects the immune system and makes babies very sick because their thymus (an important organ for immunity) doesn't work properly.
  • Babies with this condition are very vulnerable to infections and sometimes have other health issues.
  • The best treatment is a special surgery called thymus transplantation, and catching this condition early helps kids stay healthier.

The forskolin-induced swelling assay (FIS) in patient-derived intestinal organoids (PDIOs), used to determine in vitro responsiveness to elexacaftor/tezacaftor/ivacaftor (ETI), showed variability in swelling among PDIOs obtained from people with CF (pwCF) carrying the same F508del/F508del CFTR genotype. We aimed to characterise the effect of ETI on the transcriptional activity of PDIOs-derived cells to understand the intracellular processes triggered by ETI and the differences in treatment response. Six high- and six low-responding PDIOs to ETI, derived from F508del/F508del pwCF, were incubated with or without ETI for 2 to 6 h.

Objective: Radiographic assessment of sacroiliac joints (SIJs) according to the modified New York (mNY) criteria is key in the classification of axial spondyloarthritis but has moderate interreader agreement. We aimed to investigate the improvements of the reliability in scoring SIJ radiographs after applying an online real-time iterative calibration (RETIC) module, in addition to a slideshow and video alone.

Methods: Nineteen readers, randomized to 2 groups (A or B), completed 3 calibration steps: (1) review of manuscripts, (2) review of slideshow and video with group A completing RETIC, and (3) re-review of slideshow and video with group B completing RETIC.

Article Synopsis
  • The study analyzes urinary iodine levels and thyroid hormone concentrations in pregnant women with gestational diabetes mellitus (GDM) compared to healthy pregnant women, focusing on iodine status and its impact on thyroid function.
  • Results show that women with GDM have significantly lower urinary iodine concentrations and a higher prevalence of iodine deficiency compared to controls, with only a small percentage meeting optimal iodine intake.
  • Additionally, while there were no differences in serum TSH levels, hypothyroxinaemia was more common in GDM patients, and taking dietary iodine supplements was linked to fewer perinatal complications.

Article Synopsis
  • CD8 T cells are crucial for the immune response against infections and tumors, and their proliferation is stimulated by dendritic cells (DCs).
  • This study reveals that products released from thapsigargin-stimulated mast cells impair the ability of DCs to induce CD8 T-cell proliferation and Th1 cytokine production.
  • While thapsLAD2-matured DCs show some maturation markers, they produce no detectable TNF or IL-12 and are less effective than R848-matured DCs in promoting CD8 T-cell proliferation, highlighting a new way mast cells can regulate immune responses.
