Interferon alpha (IFNa) is approved for the therapy of patients (pts) with polycythemia vera (PV), a subtype of myeloproliferative neoplasms (MPN). Some pts achieve molecular responses (MR), but clonal factors sensitizing for MR remain elusive. We integrated colony formation and differentiation assays with single-cell RNA seq and genotyping in PV-derived cells vs.

Plasmodium falciparum Reticulocyte Binding Protein Homologue 5 (Pfrh5) is a promising malaria vaccine candidate, given its limited polymorphism, its essential role in parasite survival, a lack of immune selection pressure and higher efficacy against multiple parasites strains. This study evaluated the genetic diversity of Pfrh5 gene among parasites from regions with varying malaria transmission intensities in Mainland Tanzania, to generate baseline data for this potential malaria vaccine candidate.

Compensatory erythropoiesis seen during acute anemia results in an increased circulating reticulocyte count ( , immature RBC) a key factor in understanding the relationship between pre-existing anemia and burden.

Research and Development, MediBrains Social Welfare Foundation, Mumbai, IND.
Background Vitamin B12 deficiency, or cobalamin deficiency, is common among populations with low consumption of animal-based products, mainly in India, due to religious and socioeconomic factors, which significantly increase the deficiency rate. The condition has been characterized by a wide range of clinical and hematological symptoms, mainly affecting the blood and nervous system. This study aims to assess the clinical and hematological characteristics of patients with vitamin B12 deficiency and assess the therapeutic response to supplementation with vitamin B12.

University Hospital Würzburg, Department of Anaesthesiology, Intensive Care, Emergency and Pain Medicine, Würzburg, Germany.
Background: Iron deficiency (ID) is the most common nutritional deficiency among patients undergoing major surgery. Treatment of ID is straightforward, however implementing a comprehensive anemia management strategy within clinical routines is complex. Recently, reticulocyte hemoglobin content (Ret-He) has been evaluated as an early marker for ID diagnosis.
