Background: The serum calcification propensity test (or T50 test) might become a standard tool for the assessment of vascular calcification risk and T50 might be a valuable biomarker in clinical trials of treatments intended to slow the progression of vascular calcification. Literature data suggest that non-calcium-containing phosphate binders can influence T50 in chronic dialysed patients. However, it is not clear whether similar interventions are effective in patients at earlier stages of chronic kidney disease (CKD).

Anaemia is common in chronic kidney disease (CKD) and has a significant impact on quality of life (QoL), work productivity and outcomes. Current management includes oral or intravenous iron and erythropoiesis-stimulating agents (ESAs), to which hypoxia-inducible factor prolyl hydroxylase inhibitors (HIF-PHIs) have been recently added, increasing the available therapeutic options. In randomised controlled trials, only intravenous iron improved cardiovascular outcome, while some ESAs were associated with increased adverse cardiovascular events.

Clin Kidney J

August 2024

Nephrology Department, University Hospital Germans Trias i Pujol, REMAR-IGTP Group, Research Institute Germans Trias i Pujol (IGTP), Universitat Autònoma de Barcelona, Badalona (Barcelona), Catalonia, Spain.

Article Synopsis
  • Vertebral fractures (VFs) are the most common type of osteoporotic fractures and significantly affect patients by increasing mortality rates, reducing quality of life, and elevating the risk of future fractures, particularly in those with chronic kidney disease (CKD).
  • VFs are often underdiagnosed in CKD patients, and their risk factors not only include typical ones like age and bone density but also CKD-specific factors such as the severity of kidney dysfunction and treatment history.
  • Recent changes in clinical guidelines emphasize the need for better diagnosis and treatment strategies for VFs in CKD patients, urging a proactive approach to address this overlooked health issue.

January 2024

National Specialist Ophthalmic Pathology Service, Liverpool Clinical Laboratories, Liverpool University Hospitals NHS Foundation Trust, Liverpool, UK; Liverpool Ocular Oncology Research Group, Department of Molecular and Clinical Cancer Medicine, Institute of System Molecular and Integrative Biology, University of Liverpool, Liverpool, UK. Electronic address:

Several nomenclature and grading systems have been proposed for conjunctival melanocytic intraepithelial lesions (C-MIL). The fourth "WHO Classification of Eye Tumors" (WHO-EYE04) proposed a C-MIL classification, capturing the progression of noninvasive neoplastic melanocytes from low- to high-grade lesions, onto melanoma in situ (MIS), and then to invasive melanoma. This proposal was revised to the WHO-EYE05 C-MIL system, which simplified the high-grade C-MIL, whereby MIS was subsumed into high-grade C-MIL.

Immunologic constant of rejection as a predictive biomarker of immune checkpoint inhibitors efficacy in non-small cell lung cancer.

J Transl Med

September 2023

Multidisciplinary Oncology and Therapeutic Innovations Department, Aix Marseille Univ, APHM, INSERM, CNRS, CRCM, Hôpital Nord, Marseille, France.

Article Synopsis
  • Anti-PD1/PDL1 immune checkpoint inhibitors have improved outcomes for advanced non-small cell lung cancer (NSCLC) patients, but response rates are low and potential for severe side effects makes biomarker identification necessary.
  • Researchers analyzed gene expression in 44 NSCLC tumors treated with ICI, combining this with data from four public datasets to evaluate the Immunologic Constant of Rejection (ICR) as a predictor of clinical benefit.
  • The study found that certain ICR classifications were significantly associated with higher rates of Durable Clinical Benefit (DCB) from treatment, suggesting that the 20-gene ICR signature could serve as an independent biomarker for predicting response to anti-PD1/PDL1 therapy.

Pediatric Infectious Pathology Group of the French Pediatric Society, Créteil, France; University of Paris Descartes, Bicêtre Hospital, Paris, France.

Knowledge of infectious diseases and their treatments is constantly evolving. New infectious agents are regularly discovered, due mainly to improvement of identification techniques, especially the development of molecular biology and mass spectrometry. While changes in the epidemiology of infectious diseases are not always predictable or readily understood, several factors regularly enter into consideration, such as not only the natural history of diseases and the impact of vaccinations, but also the excessive and irrational use of antibiotics.

Cytidine analogs are synthetic lethal with base excision repair default due to MBD4 deficiency.

NPJ Precis Oncol

November 2022

Inactivating mutations of MBD4 have been reported in subsets of various tumors. A deficiency of this DNA glycosylase, recognizing specifically T:G mismatch resulting from the deamination of methyl-cytosine, results in a hypermutated phenotype due to the accumulation of CpG>TpG transitions. Here, we hypothesize that the difference in DNA metabolism consecutive to MBD4 deficiency may result in specific cytotoxicities in MBD4-deficient tumor cells in a synthetic lethality fashion.
