Article Synopsis
  • B cells can be engineered to produce therapies for genetic disorders, metabolic diseases, and cancer.
  • A method was developed to collect, expand, differentiate, and track B cells from non-human primates (NHPs) using radioactively labeled imaging techniques.
  • The study showed that infused B cells successfully targeted the bone marrow, spleen, and liver without serious side effects, indicating the potential for repeated treatments and the viability of NHPs as a model for human B cell medicine research.

Background: The International Index of Erectile Function (IIEF) stands out for its utility and widespread use to measure sexual function in men. However, it lacks consistency in its internal latent structure across studies, has not been evaluated for measurement invariance, and has not undergone psychometric validation for its 15-item form in Spanish among South American countries.

Aim: To examine the IIEF's psychometric evidence (ie, structural/criterion validity and reliability) in a sample of adult men and determine its measurement invariance across relationship status (single vs in a relationship) and age generations (generations Z, Y/millennials, and X).

The population of very elderly patients (aged 80 years and older) in intensive care units (ICUs) is steadily growing. These patients have unique physiological, cognitive, functional, and social characteristics that affect their entire ICU course. Immobility, delirium, dysphagia, malnutrition, and polypharmacy are among the most common geriatric syndromes in these patients, and they contribute to a higher risk of acute and long-term functional decline and mortality.

Immune thrombocytopenic purpura (ITP) is an uncommon condition resulting from the autoimmune destruction of platelets. A man in his mid-30s, who had received three doses of the SARS-CoV-2 vaccine a year prior, was diagnosed with ITP 3 weeks after contracting COVID-19. Mechanisms of SARS-CoV-2 induced thrombocytopenia may include bone marrow depletion, coagulation consumption, mutations resulting in cytokine release or molecular mimicry leading to autoimmunity.
