Improved Safety of Nucleic Acid Amplification Technology Combined With Serological Tests for Screening Blood Donors: A Systematic Review and Meta‐Analysis

Reviews in Medical Virology, Volume 36, Issue 2, March 2026.
ABSTRACT No laboratory test performed to date provides an absolute guarantee for detecting infectious agents. Nucleic acid amplification techniques/tests (NAT) associated with serological tests can increase safety and provide greater diagnostic accuracy for patients. We investigated the added safety of NAT technology combined with serological tests for

Plasma Proteomic Profile of Chemotherapy‐Induced Severe Neutropenia: A Pilot Discovery Phase Study

The FASEB Journal, Volume 40, Issue 3, 15 February 2026.
Immune system, hemostasis, and protein metabolism are the major biological mechanistic effects affected by chemotherapy‐induced myelotoxicity treatment, which may underline tissue damage and systemic responses seen in patients' follow‐up treatment. ABSTRACT Transient severe neutropenia and thrombocytopenia are frequent during treatment of hematological

Attenuated Infectious Bronchitis Virus (IBV) Vaccination Induces Protective Humoral and Cellular Immunity Against SARS‐CoV‐2 in Mammals

Journal of Immunology Research, Volume 2026, Issue 1, 2026.
Occupational exposure to infectious bronchitis virus (IBV) has been associated with cross‐reactivity to other coronaviruses such as SARS‐CoV‐2. In this study, we investigated the immune response of IBV using reconstituted samples of the commercial H120 Mass‐I vaccine (Zoetis) against SARS‐CoV‐2 infection.
