Patients with sickle cell abnormalities undergoing surgery are generally considered to be at greater risk for perioperative complications. We present a 25-year-old woman with sickle cell disease (SCD) and severe aortic insufficiency. A minimally invasive, warm, beating heart approach was adopted to try and minimize the risk of sickling due to cardiopulmonary bypass (CPB), low-flow states, cold cardioplegia and aortic cross-clamping. Compared to classical methods, we believe our technique further reduces the risk of systemic and organ hypothermia and thus, sickling.

Background: The coexistence of sickle cell anemia and multiple sclerosis in a single patient presents a rare and challenging clinical scenario, possibly favoured by the interplay between chronic inflammatory states and autoimmune processes.
Methos/results: We present the case of a 36-year-old woman with sickle cell anemia who developed progressive neurological symptoms leading to frequent falls and paraparesis; magnetic resonance imaging showed many periventricular, infratentorial, and both cervical and dorsal spinal cord lesions, leading to a diagnosis of multiple sclerosis. After a multidisciplinary approach the patient was successfully started on ofatumumab.

Advancing nursing practice to improve care and system outcomes requires doctoral-prepared nurses to conduct programs of research and translate science to practice. The authors describe a Doctoral support group (DSG) at one hospital designed to support nurses considering and navigating doctoral education while continuing as hospital employees. Strategies from 18 years' experience are provided for others to develop and sustain a DSG as part of an environment to support and retain nurses with doctoral degrees.

Sickle cell disease (SCD) is a hereditary hemolytic anemia associated with the alteration of the membrane composition of the sickle erythrocytes, the loss of glycolysis, dysregulation of the pyruvate phosphatase pathway, and changes in nucleotide metabolism of the sickle red blood cell (RBC). This review provides a comprehensive overview of the impact of the presence of Hb S, which leads to the disruption of the normal RBC metabolism. The intricate interplay between the redox and energetic balance in erythrocytic cells, where the glycolysis, pentose phosphate pathway, and methemoglobin reductase pathways are all altered in sickle RBC, is a key focus.

A 31-year-old male patient with a history of sickle cell disease (SCD) with stage V chronic kidney disease (CKD) presented for a deceased donor kidney transplant. During surgery, the transplanted kidney showed mottling and limited cortical flow, raising concerns for an intraoperative sickle cell crisis versus hyperacute rejection. Postoperative imaging revealed decreased vascularity, and the patient was treated with RBC exchange.
