Unusual Co-Occurrence of Multiple Myeloma and AML in a Patient With Germline CEBPA Variant. Expanding the Spectrum of Hereditary Hematologic Malignancies.

Timeline and genetic analysis of a 55-year-old female with a family history of gastric cancer and multiple myeloma, who was diagnosed with AML and a germline CEBPA variant.

Case Report: Mycosis fungoides as an exclusive manifestation of common variable immunodeficiency in a family with a gene mutation.

Background: Common variable immunodeficiency disorders (CVIDs), which are primary immunodeficiencies characterized by the failure of primary antibody production, typically present with recurrent bacterial infections, decreased antibody levels, autoimmune features, and rare atypical manifestations that can complicate diagnosis and management. Although most cases are sporadic, approximately 10% of the patients may have a family history of immunodeficiency. Genetic causes involving genes related to B-cell development and survival have been identified in only a small percentage of cases.

Search for Heavy Neutral Leptons in Decays of W Bosons Using a Dilepton Displaced Vertex in sqrt[s]=13 TeV pp Collisions with the ATLAS Detector.

A search for a long-lived, heavy neutral lepton (N) in 139  fb^{-1} of sqrt[s]=13  TeV pp collision data collected by the ATLAS detector at the Large Hadron Collider is reported. The N is produced via W→Nμ or W→Ne and decays into two charged leptons and a neutrino, forming a displaced vertex. The N mass is used to discriminate between signal and background.
