PURPOSE: To examine the stability of postmortem glycated hemoglobin (HbA1c) measurement and its relationship to premortem glycemia. METHODS: Postmortem blood samples were obtained from 32 donors (8 known diabetic) and shipped on ice to a central laboratory to examine the stability of HbA1c measurements during the first 9 postmortem days. Thirty-nine other suspected diabetic donors underwent comparison of premortem and postmortem HbA1c measurements. RESULTS: Postmortem HbA1c measurements remained stable after 9 postmortem days (all measurements within ±0...

Blood banking is an essential aspect of modern medical care. When red blood cells (RBCs) are stored, they become damaged by various chemical processes, such as accumulation of their own waste products and oxidative injury, among others. These processes lead to the development of the RBC storage lesion, a complex condition where the severity is reflected through the morphology of the stored cells. It was hypothesized that Raman spectroscopy could be used to monitor certain structural and compositional changes associated with such ageing effects and that a relationship between these features and traditional morphology (as measured using a morphology index) could be observed...

Accumulating evidence suggests that O3 exposure may contribute to CNS dysfunction. Here, we posit that inflammatory and acute-phase proteins in the circulation increase after O3 exposure and systemically convey signals of O3 exposure to the CNS. To model acute O3 exposure, female Balb/c mice were exposed to 3 ppm O3 or forced air for 2 h and were studied after 6 or 24 h. Of 23 cytokines and chemokines, only KC/CXCL1 was increased in blood 6 h after O3 exposure. The acute-phase protein serum amyloid A (A-SAA) was significantly increased by 24 h, whereas C-reactive protein was unchanged...

BACKGROUND: Blood donors are, in principle, healthy individuals who may be revealed as infectious for blood-borne agents by the laboratory screening process, depicting the asymptomatic burden of the disease. Therefore, monitoring hepatitis C virus (HCV)-infected donor and human immunodeficiency virus (HIV)-infected donor and associating to their demographical and behavioural characteristics may shed light on the dynamics and contemporary changes in these viruses' epidemiology. METHODS: Donors presenting repeatedly reactive HCV or HIV serology/nucleic acid testing (NAT) screening results were submitted to confirmatory testing...

The transfusion of platelets is essential for diverse pathological conditions associated with thrombocytopenia or platelet disorders. To maintain optimal platelet quality and functions, platelets are stored as platelet concentrates (PCs) at room temperature under continuous agitation-conditions that are permissive for microbial proliferation. In order to reduce these contaminants, pathogen reduction technologies (PRTs) were developed by the pharmaceutical industry and subsequently implemented by blood banks...

BACKGROUND: During its 120 days sojourn in the circulation, the red blood cell (RBC) remodels its membrane. Acetylcholinesterase (AChE) is a glycosylphosphatidylinositol (GPI)-linked enzyme that may serve as a marker for membrane processes occurring this ageing-associated remodelling process. MATERIALS AND METHODS: Expression and enzymatic activity of AChE were determined on RBCs of various ages, as obtained by separation based on volume and density (ageing in vivo), and on RBCs of various times of storage in blood bank conditions (ageing in vitro), as well as on RBC-derived vesicles...

BACKGROUND: The release of damage-associated molecular pattern molecules (DAMPs) in the extracellular space secondary to injury has been shown to cause systemic activation of the coagulation system and endothelial cell damage. We hypothesized that pediatric trauma patients with increased levels of histone-complexed DNA fragments (hcDNA) would have evidence of coagulopathy and endothelial damage that would be associated with poor outcomes. METHODS: We conducted a prospective observational study of 149 pediatric trauma patients and 62 control patients at two level 1 pediatric trauma centers from 2013-2016...

Proteomics, the large-scale study of protein expression in cells and tissues, is a powerful tool to study the biology of clinical conditions and has provided significant insights in many experimental systems. Herein, we review the basics of proteomic methodology and discuss challenges in using proteomic approaches to study autism. Unlike other experimental approaches, such as genomic approaches, there have been few large-scale studies of proteins in tissues from persons with autism. Most of the proteomic studies on autism used blood or other peripheral tissues; few studies used brain tissue...

OBJECTIVE: To examine the outcomes of trauma patients who tested positive for alcohol at the time of hospital arrival versus those who tested negative. METHODS: Data were pulled from the National Trauma Data Bank (2007-2010). All injured patients who were ≥14 years of age, sustained a "blunt" or "penetrating" injury, had complete systolic blood pressure (SBP) and heart rate (HR) records, were taken to a level 1 or 2 trauma center, and who received a confirmed blood alcohol test were included in the study...

BACKGROUND: The platelet (PLT) storage lesion is in part caused by the collection and/or production process. Pathogen inactivation (PI) further accelerates its development leading to a reduced in vitro PLT functionality and hence quality. Although the treatment of PLT concentrates (PCs) with riboflavin and ultraviolet light PI should occur within 22 hours of collection, in this study the impact of treatment timing on in vitro PLT quality was investigated. STUDY DESIGN AND METHODS: Apheresis PCs were PI treated on the day of production or on Days 1, 3, or 4 of storage or left untreated as control...

BACKGROUND: Development of a tuberculosis vaccine to boost BCG is a major international health priority. SRL172, an inactivated whole cell booster derived from a non-tuberculous mycobacterium, is the only new vaccine against tuberculosis to have demonstrated efficacy in a Phase 3 trial. In the present study we sought to determine if a three-dose series of DAR-901 manufactured from the SRL172 master cell bank by a new, scalable method was safe and immunogenic. METHODS: We performed a single site, randomized, double-blind, controlled, Phase 1 dose escalation trial of DAR-901 at Dartmouth-Hitchcock Medical Center in the United States...
