Pure red cell aplasia in a Holstein calf

AbstractA 3-month-old Holstein calf presented with lethargy. Hematological examination showed severe non-regenerative anemia without reduction in white blood cell and platelet counts. Serum biochemical analysis revealed both high erythropoietin activity and high serum iron concentration. Bone marrow examination revealed selectively decreased erythroid precursors and an increased myeloid:erythroid ratio of 7:1. Lesions that could have caused anemia were found only in bone marrow by necropsy. The calf was diagnosed with pure red cell aplasia (PRCA) based on these clinical and pathological findings. Although the cause of PRCA was not identified, this is the first confirmed clinical report of PRCA in a Holstein calf.

Knowledge gaps exist in how we implement aerobic exercise programs during the early phases post-stroke. Therefore, the objective of this review was to provide evidence-based guidelines for pre-participation screening, mobilization, and aerobic exercise training in the hyper-acute and acute phases post-stroke. In reviewing the literature to determine safe timelines of when to initiate exercise and mobilization we considered the following factors: arterial blood pressure dysregulation, cardiac complications, blood-brain barrier disruption, hemorrhagic stroke transformation, and ischemic penumbra viability. These stroke-relat...

Here we review the diagnosis and management of occlusive renal vascular lesions due to APS and other TMAs, with a focus on patients with SLE and lupus nephritis. The presence of a thrombotic event, unexplained hypertension, thrombocytopenia, or hemolytic anemia should prompt considerat...

ConclusionPBM in obstetrics is based on three main pillars: diagnostic and/or therapeutic interventions during pregnancy, during delivery and in the postpartum phase. These three main pillars should be kept in mind by all professionals taking care of pregnant women, including obstetricians, general practitioners, midwifes, and anaesthesiologists, to improve pregnancy outcome and optimize resources.
