The association between anemia and chronic renal failure has been recognized since the early 19th century. With the introduction of regular dialysis treatment, an understanding of all aspects of this uremic complication has become of great importance, including an appreciation of the hazards of multiple blood transfusions. This analysis of hemoglobin levels and transfusion requirements in 84 dialysis patients focuses specific attention on hemolytic mechanisms, blood loss, and the effect of bilateral nephrectomy on erythropoiesis. Because no replacement for renal erythropoietin is available, particular attention must be paid to less important, but partially correctable factors that contribute to anemia. Blood transfusion requirements can then be reduced to a minimum, together with the risks of hypersplenism, hepatitis, and sensitization of the patient to alloantigens.

Clinical Characteristics and Risk Factors for Multidrug-Resistant Complex Bacteremia in a Chinese Tertiary Hospital: A Decade Review (2013-2022).
Infect Drug Resist
January 2025
Department of Laboratory Medicine, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School, Nanjing, Jiangsu, People's Republic of China.
Objective: This study aimed to analyze the antimicrobial resistance profiles, clinical characteristics and risk factors of bacteremia caused by complex (ECC) strains.
Methods: We retrospectively collected clinical data from patients diagnosed with ECC bacteremia between 2013 and 2022 in a tertiary hospital in Jiangsu. Subgroup analyses were performed based on multidrug resistance (MDR), nosocomial acquisition, polymicrobial bacteremia, and mortality.
Clinical and Radiological Outcomes of Extreme Lateral Interbody Fusion (XLIF) in the Treatment of Lumbar Spondylodiscitis: A Multi-center Study.

Orthopedics, Hospital Putrajaya, Putrajaya, MYS.
Introduction Lumbar pyogenic spondylodiscitis is a challenging and rare spinal infection with high morbidity, particularly in patients with comorbidities. While the extreme lateral interbody fusion (XLIF) technique is established in treating degenerative spinal conditions, its efficacy in managing spondylodiscitis is less well-studied. This study aims to evaluate the clinical and radiographic outcomes of the XLIF approach combined with posterior instrumentation in patients with lumbar spondylodiscitis.

Aim: This retrospective study explored the association between donor and recipient sex on hospital-onset sepsis (HO-sepsis) and Hb changes in critically ill patients receiving red blood cell (RBC) transfusions.
Methods: Data from 2010-2020 were extracted from an academic hospital's clinical database and a blood supplier's donor database.
Upper Gastrointestinal Bleeding: A Retrospective, Single-Center Experience on the Role of Endoscopy and Outcomes.

Department of Clinical Sciences, Malmo, Lund University, Malmo, Sweden.
Background: Upper gastrointestinal bleeding (UGIB) is a common and potentially fatal medical emergency. This study aimed to investigate the frequency, causes, outcomes, and efficacy of endoscopy in the treatment of UGIB at King Fahad Central Hospital in Jazan, Saudi Arabia.
Methods: Between January 2017 and December 2023, a retrospective study was performed including all hospitalized patients with UGIB.
REBLEEDING RATE AND THE NEED OF BLOOD TRANSFUSION ARE HIGHER IN PATIENTS WITH UPPER GASTROINTESTINAL TUMOR BLEEDING THAN IN PATIENTS WITH PEPTIC ULCER BLEEDING.
Acta Clin Croat
December 2023
Division of Gastroenterology, Department of Internal Medicine, Sestre milosrdnice University Hospital Center, Zagreb, Croatia.
The aim of our 5-year study (from January 2008 to December 2012) was to compare the incidence of peptic ulcer bleeding (PUB) to bleeding from tumors of the upper gastrointestinal tract. The percentage of re-bleeding within the first 30 days of hospital admission, as well as the need of blood transfusions, are also reported. Statistical data were collected on 2198 patients who were treated in our emergency department due to upper gastrointestinal bleeding (UGIB) in the form of melena or hematemesis.
