Transfusion

Hemorrhagic shock is a major source of morbidity and mortality worldwide. While whole blood or blood product transfusion is a first line treatment, maintaining robust supplies presents significant logistical challenges, particularly in autere environments. OMX is a novel non-hemoglobin (Hb)-based oxygen carrier derived from the H-NOX (Heme-Nitric Oxide/Oxygen binding) protein family. Due to their engineered oxygen (O2) affinities, OMX proteins only deliver O2 to severely hypoxic tissues. Additionally, unlike Hb-based oxygen carriers, OMX proteins do not scavenge nitric oxide in the vasculature...

To evaluate the safety and feasibility of continued perioperative aspirin at the time of robotic assisted simple prostatectomy (RASP). We performed a retrospective review of our IRB approved institutional database of patients who underwent RASP between 2013 and 2022. Comparative groups included patients taking aspirin in the perioperative period and those not taking aspirin pre-operatively. The primary outcome was any post-operative bleeding related complication using the modified Clavien-Dindo classification...

INTRODUCTION: Tranexamic acid (TXA) administration is supported by numerous evidence in reducing blood loss after total knee arthroplasty (TKA). The combination of intravenous (IV) and intra-articular (IA) TXA administration revealed good result in blood loss reduction with less evidence of venous thromboembolism event (VTE). Several literature reviews portray that peri-articular (PA) administration yields similar hemostasis in comparison to IV route. However, there is no report on the clinical effect of combining PA + IA TXA in blood loss reduction and its complications, compared to combining IV + IA TXA after TKA...

BACKGROUND: The COVID-19 pandemic impacted the US blood supply. We compared blood donor demography and infectious disease prevalence before and during the pandemic using a large multicenter database. METHODS: Data were categorized as "Before COVID-19" (March 2018-February 2020) or "During COVID-19" (March 2020-February 2022). Donor demographics, donation frequency, and infectious marker prevalence of HIV, HBV, and HCV were compared for the two time periods. The odds of a donor testing positive for these infections among the two time periods were calculated using multivariable logistic regression...

BACKGROUND: Laboratory results are frequently abnormal in pregnant mothers. Abnormalities usually relate to pregnancy or associated complications. Hematological abnormalities and age in pregnancy may increase the likelihood for transfusion and mortality. STUDY DESIGN AND METHODS: Hematological profiles and transfusion history of pregnant mothers presenting to a tertiary hospital, were evaluated over 2 years. Age, anemia, leukocytosis and thrombocytopenia were assessed for transfusion likelihood...

BACKGROUND: Limited studies have explored the association between clinical symptoms and titers of SARS-CoV-2 antibodies. STUDY DESIGN AND METHODS: In this cross-sectional study, whole-blood donors who had experienced a confirmed or suspected COVID-19 infection completed questionnaires at the time of blood donation. Plasma SARS-CoV-2 immunoglobulin G (IgG) titers were measured using an enzyme-linked immunosorbent assay. Logistic regression models were used to calculate odds ratios (ORs) for high-titer COVID-19 convalescent plasma (CCP) for each variable...

BACKGROUND: Despite being the largest racial/ethnic minority group in the United States, Hispanic/Latinos (H/L) are significantly underrepresented among blood donors. A lack of proximal blood donation opportunities may be one factor contributing to these disparities. However, few studies have investigated this possibility. STUDY DESIGN AND METHODS: Proprietary data on mobile blood collections in Maricopa County, Arizona, were gathered for the period of January 01, 2022 to April 30, 2022 and paired with census tract information using ArcGIS...

BACKGROUND: Evidence supports a restrictive platelet transfusion threshold in preterm neonates. We aimed to describe the effect of implementing this threshold on transfusion rates. STUDY DESIGN AND METHODS: This retrospective observational cohort study included all very preterm infants (born <32 weeks' gestation) admitted to a neonatal intensive care unit between 2004 and 2022, divided into three epochs. Platelet transfusion thresholds changed from 30 × 109 /L for stable neonates and 50 × 109 /L for unstable neonates (January 2004 to December 2009) to 20 × 109 /L for stable neonates and 50 × 109 /L for unstable neonates (January 2010 to June 2019) to 25 × 109 /L for non-bleeding neonates and 50 × 109 /L for neonates with major bleeding (July 2019 to July 2022)...

Thalassemia is most widely distributed single gene autosome recessive genetic disease in the world, whose clinical manifestation was changed from asymptomatic anemia to severe anemia requiring continous blood transfusion to maintain life, thus resulting in a serious economic burden to society and families. Therefore, it is necessary to carry out the corresponding prentatal screening and diagnosis. Most of the conventional detection methods can only detect the common thalassemia genotype, it can easy to cause misdiagnosis or missed diagnosis for those rate genetic variantions...

OBJECTIVE: To explore the plasma metabolomic characteristics of children with transfusion-dependent thalassemia (TDT), and reveal the changes of metabolic pattern in children with TDT. METHODS: 23 children with TDT who received regular blood transfusion in Ganzhou Women and Children's Health Care Hospital in 2021 were selected, and 11 healthy children who underwent physical examination during the same period were selected as the control group. The routine indexes between children with TDT and the control group were compared, and then the metabolic composition of plasma samples from children with TDT and the control group was detected by liquid chromatography-mass spectrometry...

OBJECTIVE: To analyze the effect of recombinant human thrombopoietin (rhTPO) on platelet (PLT) reconstitution after autologous peripheral blood stem cell transplantation (APBSCT) in patients with multiple myeloma (MM). METHODS: The clinical data of 147 MM patients who were diagnosed in the First Affiliated Hospital of Soochow University and received APBSCT as the first-line therapy were retrospectively analyzed. According to whether rhTPO was used during APBSCT, the patients were divided into rhTPO group (80 cases) and control group (67 cases)...

INTRODUCTION: Surgical care practitioners (SCPs) are non-medical workers involved in various aspects of the management of surgical patients. The role includes assisting and performing surgical procedures. More than 60,000 laparoscopic cholecystectomies (LC) are performed annually in the UK. With ever-increasing pressure on waiting lists, it is important to look at fully utilising the skills of our entire workforce. We report what we believe is the first published series of LC performed by an SCP...

BACKGROUND: Postoperative delirium, particularly prevalent in elderly patients after abdominal cancer surgery, presents significant challenges in clinical management. AIM: To develop a synthetic minority oversampling technique (SMOTE)-based model for predicting postoperative delirium in elderly abdominal cancer patients. METHODS: In this retrospective cohort study, we analyzed data from 611 elderly patients who underwent abdominal malignant tumor surgery at our hospital between September 2020 and October 2022...

Chronic Lymphocytic Leukemia (CLL) is the most common type of leukemia in the US, representing approximately 1.1% of all new cancers diagnosed. Most patients with CLL can be monitored without treatment, and the indicated treatment options include a CD20 monoclonal antibody with or without bruton tyrosine kinase (BTK) inhibitors, phosphatidylinositol 3-kinase (PI3K) inhibitors, and B-cell lymphoma 2 (BCL2) antagonists. We review the case of a 77-year-old female with a long-standing history of CLL predominant lymphocytosis, transfusion -independent anemia, and thrombocytopenia...

Pakistan has been a hub of several HIV outbreaks over the last 2 decades, with four major outbreaks being registered since 2018. There has been a recent rise in HIV infections, especially in high-risk populations, mainly consisting of people who inject drugs, men who have sex with men, prisoners, the transgender women community, and female sex workers. Consistently poor infection control practices, unregulated unsafe blood transfusion, questionable ethical practices by healthcare providers, and a general lack of awareness are the main drivers of recent HIV outbreaks, with these issues exacerbated by the presence of untrained health care providers...

Here, we describe a 7-year-old girl who was diagnosed with an early-onset Crohn's disease in the setting of COVID-19 illness. Her disease process responded poorly to standard infliximab dosing, necessitating repeat hospitalizations and red blood cell transfusions. Remission was subsequently induced using a personalized infliximab pharmacokinetic profile based on therapeutic drug monitoring. While the initial data does not support a link, several case reports suggest an association between COVID-19 illness and de-novo development of IBD, especially in young female patients...

BACKGROUND: Anemia is one of the common complications of chronic kidney disease (CKD), and its prevalence has been arising globally. The key cause of anemia in CKD patients is the diseased kidney's reduced ability to synthesize endogenous erythropoietin (EPO), yet this is not the sole reason. Inflammatory elements, functional iron deficiency, and uremic toxins together participate in the development of anemia. According to research data, anemia is an independent risk factor for cardiovascular events, all-cause mortality, and worsening renal function and affects the clinical prognosis and quality of life of CKD patients...

OBJECTIVE: This study aims to study the efficacy of exchange transfusion in complicated malaria with hyperparasitaemia. METHOD: This is a retrospective case-control study conducted in a tertiary care referral hospital in northeastern India. A retrospective chart review was done, and 34 children with hyperparasitaemia were identified. Of these, 16 children received only antimalarial chemotherapy, and 18 received adjunct exchange blood transfusion (EBT). The data was analyzed for survival benefit as the main outcome measure...

A recently approved drug that induces erythroid cell maturation (luspatercept) has been shown to improve anemia and reduce the need for blood transfusion in non-transfusion-dependent as well as transfusion-dependent β-thalassemia (BT) patients. Although these results were predominantly positive, not all the patients showed the expected increase in hemoglobin (Hb) levels or transfusion burden reduction. Additional studies indicated that administration of luspatercept in transfusion-dependent BT was associated with increased erythropoietic markers, decreased hepcidin levels, and increased liver iron content...
