Article Abstract
A review of all blood culture isolates for the 16 years from 1976 were collated with prospective laboratory and clinical records of 620 sickle cell patients treated at King's College Hospital. Over half of all salmonella bacteraemias diagnosed in the clinical laboratory occurred in sickle cell disease (SCD) patients. Of 21 bacteraemias in SCD patients, 11 (52.3%) were due to Salmonella spp. compared with 23 (0.4%) of 4884 bacteraemias in patients without SCD (P = < 0.00001). In SCD, Gram-negative bacilli were responsible for 16 (76.2%) bacteraemias, of which 11 (68.8%) were due to Salmonella spp. but there were no cases of S. typhi or S. paratyphi. An increase in the number of salmonella infections over the past 5 years were noted in the SCD and non-SCD patients, nine and 16 cases respectively, compared with two and seven cases in the previous decade. However, the recent increase of S. enteritidis phage type 4 in the UK was not evident in SCD patients. These findings have important preventative and therapeutic implications for the management of SCD patients.

BACKGROUND As the population ages, comorbidities among elderly patients are becoming a significant problem, due to associated risks and mortality. Medication adherence is crucial for controlling chronic diseases and improving patient outcomes; therefore, it is important to understand medication adherence among hospitalized patients. MATERIAL AND METHODS A cross-sectional study was conducted from June 2023 to April 2024 in 2 tertiary hospitals in Wuhu City, Anhui Province, China.

Background: Red blood cell (RBC) utilization in patients with sickle cell disease (SCD) in Canada is poorly defined. This study describes RBC utilization in an SCD cohort at a single Canadian center.
Study Design And Methods: All adults with SCD who received care at the Ottawa Hospital between January 2006 and May 2019 were included, and followed until December 2021.
Sickle cell disease (SCD) is the most common genetic disease in the world and a societal challenge. SCD is characterized by multi-organ injury related to intravascular hemolysis. To understand tissue-specific responses to intravascular hemolysis and exposure to heme, we present a transcriptomic atlas in the primary target organs of HbSS vs HbAA transgenic SCD mice.

Brugada syndrome (BrS) is a genetic condition that increases the risk of life-threatening arrhythmias, which can result in sudden cardiac death (SCD). Implantable loop recorders (ILRs) have become a key tool in managing patients with unexplained syncope, and guidelines advise their use in individuals with recurrent, unexplained syncope or palpitations. However, the role of ILRs in inherited arrhythmic conditions like BrS remains a topic of debate.

This study aimed to evaluate differences in average velocity (AV, mm/s), blood flow (BF, μL/min) and vessel diameter (VD, μm) from the temporal retinal arcades in SCD compared to healthy eyes using Doppler optical coherence tomography (DOCT).
Patients And Methods: A cross-sectional study was conducted between 2021 and 2023.
