Sickle cell disease (SCD) is an inherited disorder in which sickled red blood cells occlude the small vessels of the body, reducing oxygen delivery to tissues and ultimately negatively affecting many of the body's major organs. Hydroxyurea has proven beneficial in the treatment of SCD and prevention of disease-related complications. The 2014 guidelines put forth by the National Heart, Lung, and Blood Institute recommend hydroxyurea treatment in infants 9 months and older, children, and adolescents with SCD-SS or SCD-Sβ(0) thalassemia regardless of clinical severity. This is a change from the 2002 guidelines in which hydroxyurea was recommended for adolescents and children with SCD-SS or SCD-Sβ(0) thalassemia with frequent episodes of pain, a history of acute chest syndrome, severe and symptomatic anemia or other severe vaso-occlusive events. Nurses play a critical role in working with patients and families to provide education, guidance, and support to improve compliance to mitigate the long-term effects of SCD.

TARGETING LUNG HEME IRON BY AEROSOL HEMOPEXIN ADMINSTRATION IN SICKLE CELL DISEASE PULMONARY HYPERTENSION.

Lung tissue from human patients and murine models of sickle cell disease pulmonary hypertension (SCD-PH) show perivascular regions with excessive iron accumulation. The iron accumulation arises from chronic hemolysis and extravasation of hemoglobin (Hb) into the lung adventitial spaces, where it is linked to nitric oxide depletion, oxidative stress, inflammation, and tissue hypoxia, which collectively drive SCD-PH. Here, we tested the hypothesis that intrapulmonary delivery of hemopexin (Hpx) to the deep lung is effective at scavenging heme-iron and attenuating the progression of SCD-PH.

Anesthesiology, the medical specialty that deals with the management of vital functions in patients undergoing surgery, has played an important role in the successful development of cardiac interventions worldwide. Tracing the historical roots of cardiac anesthesia and critical care from its inception in the late 1950s, a paradigm shift in perioperative care has been driven by a better understanding of the mechanisms of organ dysfunction in stressful conditions and technological advances regarding surgical approach, patient monitoring, and organ protection. Although progress in cardiac anesthesia and critical care lagged a little behind in Caribbean territories, successful achievements have been accomplished over the last forty years.

This study aimed to identify asymptomatic brain lesions in patients with β-thalassemia major (TM) and sickle cell anemia (SCA) and evaluate the correlation of these lesions with factors such as splenectomy, thrombocytosis, and blood transfusions. A total of 26 patients with thalassemia major and 23 patients with sickle cell anemia were included. Ischemic lesions were categorized as lacunar, small vessel, or multifocal.

Background: This study aimed to describe Sickle Cell Disease (SCD) phenotypes, sociodemographic characteristics, healthcare, and clinical outcomes of patients with SCD attending Mnazi Mmoja Hospital (MMH) in Zanzibar.
Methods: Individuals who visited MMH between September 2021 and December 2022 and were known or suspected to have SCD were enrolled in the clinic. Sociodemographic characteristics and clinical features were documented, and laboratory tests were performed.
