Backround Intraventricular hemorrhage (IVH) remains a dangerous and frequent complication in very low birth weight (VLBW) infants. Activated factor VII (aFVII) activates the coagulation cascade and is a potential tool for stopping active bleeding, including limiting the extent of an IVH. This retrospective treatment observation compared data for infants with IVH progression treated with fresh frozen plasma (FFP) alone or with a combination of FFP and aFVII. Methods/Intervention All infants were subject to cranial ultrasonography at least twice daily...

Treatment and outcome of systemic lupus erythematosus (SLE) in C1q deficient patients are rarely reported. The aim of this report is to share our experience about the course of management of three cases diagnosed as SLE with C1q deficiency, in light of present literature. Initial and dominant complaints of three cases from two different families were cutaneous manifestations. One patient was also diagnosed with arthritis and thrombocytopenia. Antinuclear antibody was positive in all cases, whereas anti-dsDNA was negative with normal levels of complement C3, C4 and decreased CH50 activity...

BACKGROUND: Reversal of therapeutic anticoagulation prior to emergency neurosurgical procedures is required in the setting of intracranial hemorrhage. Multifactor prothrombin complex concentrate (PCC) promises rapid efficacy but may increase the probability of thrombotic complications compared to fresh frozen plasma (FFP). OBJECTIVE: To compare the rate of thrombotic complications in patients treated with PCC or FFP to reverse therapeutic anticoagulation prior to emergency neurosurgical procedures in the setting of intracranial hemorrhage at a level I trauma center...

ABO incompatible (ABOi) organ transplantation requires pre-transplant reduction of the recipient's IgG and IgM isoagglutinin titer against the donor to prevent hyperacute rejection. Over the past four years we primarily used unspecific IgG immunoadsorption (IA) for this purpose and combined this selectively with membrane filtration (IAc) to reduce IgM isoagglutinines. In patients with an initial IgG titer against donor below 1:64, plasma exchange (PE) was initiated. In this retrospective analysis covering January 2012 to August 2015 we compared how efficiently IgG and IgM isoagglutinines in a total of 22 ABOi kidney transplant recipients were reduced by either IA (n = 75 sessions), IAc (n = 14 sessions) or PE (n = 40 sessions)...

OBJECTIVE: The main objective of this study is to analyse the circumstances and management of peripartum hysterectomies performed on patients with placenta percreta. METHODS: This study included 37 patients who were diagnosed with placenta percreta, a condition in which the placenta invades the uterine wall, and who therefore underwent a peripartum hysterectomy. Their demographic characteristics, history of past caesareans, uterine surgery and curettage, duration of hospitalization, admission to an intensive care unit, neonatal outcomes, skin and uterus incision type, hypogastric artery ligation (HAL), complications, quantities of transfused ES (erythrocyte suspensions), and FFP (fresh frozen plasma), maternal morbidity and mortality and postoperative pathology results were retrospectively reviewed...

Matthew D Wilson, Jonathan E Davis
The actively bleeding anticoagulated patient presenting to the emergency department requires rapid evaluation and treatment, which is made increasingly complicated by the ever-evolving antithrombotic treatment options used in medicine. Even with excellent supportive care, the timeliness with which reversal decisions need to be made continues to demand of the emergency practitioner a familiarity with the properties and general characteristics of a variety of antithrombotic agents. Reversal options vary and may include vitamin K, FFP, PCC, rFVIIa, platelets, and desmopressin, among others...

BACKGROUND: Plasma-first resuscitation attenuates trauma-induced coagulopathy (TIC); however, the logistics of plasma-first resuscitation require thawed plasma (TP) be readily available due to the obligatory thawing time of fresh frozen plasma (FFP). The current standard is storage of TP for up to 5 days at 4°C, based on factor levels at outdate, for use in patients at risk for TIC, but there remains a 2.2% outdated wastage rate. However, the multitude of plasma proteins in attenuating TIC remains unknown...

INTRODUCTION: The current management of severely injured patients includes damage control resuscitation strategies that minimise the use of crystalloids and emphasise earlier transfusion of red blood cells (RBC) to prevent coagulopathy. In 2012, London's air ambulance (LAA) became the first UK civilian pre-hospital service to routinely carry RBC to the trauma scene. OBJECTIVE: To investigate the effect of pre-hospital RBC transfusion (phRTx) on overall blood product consumption...

BACKGROUND: Veno-occlusive disease(VOD)is a fatal coagulopathy, which is caused by an endothelial disorder among patients who undergo hematopoietic stem cell transplantation(SCT). Some protective agents, such as administration of fresh frozen plasma(FFP), have been evaluated for both prophylactic and targeted therapy. PURPOSE: We evaluated the prophylactic efficacy of FFP for VOD in a retrospective study. METHODS: We surveyed patients who received SCT in our hospital between January 2011 and December 2011...

INTRODUCTION: Epigenetics has been identified in multiple diseases. The effect of transfusion strategy on epigenetics is unknown. We hypothesized that expression of epigenetic regulating genes would be associated with resuscitation strategy following blunt trauma. METHODS: Retrospective study using the inflammation in host response to injury (glue grant) dataset. Volume transfused over 24 hours of packed red blood cells (PRBC), Fresh Frozen Plasma(FFP), Platelets(PLT) as well as crystalloids was extracted along with leucocyte microarray data of genes with known epigenetic modulating activity from day 1 after injury...

INTRODUCTION: Orthotopic liver transplantation (OLT) can be associated with significant bleeding requiring multiple blood product transfusions. Rotational thromboelastometry (ROTEM) is a point-of-care device that has been used to monitor coagulation during OLT. Whether it reduces blood loss/transfusions during OLT remains controversial. MATERIALS AND METHODS: We aim to compare ROTEM with conventional coagulation tests (aPTT, PT, INR, platelet count, fibrinogen) to guide transfusion of platelets, cryoprecipitate, and fresh frozen plasma (FFP) during OLT over 3 years...

We experimentally and numerically investigate the applicability of the conventional near-field pattern, far-field pattern (FFP), and variable aperture (VA) methods for measuring the effective mode-field diameter (MFD) of the higher-order modes, which can be used for accurately evaluating splice loss. We confirmed that the variation in the MFD values obtained with the FFP and VA methods can be converged by considering the minimum scanning angle and the minimum aperture angle, respectively, for both fundamental and higher-order modes...

The presence of bulky disease in Hodgkin lymphoma (HL), traditionally defined with a 1-dimensional measurement, can change a patient's risk grouping and thus the treatment approach. We hypothesized that 3-dimensional measurements of disease burden obtained from baseline (18)F-fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) scans, such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG), would more accurately risk stratify patients. To test this hypothesis, we reviewed pretreatment PET-CT scans of patients with stage I-II HL treated at our institution between 2003-2013...

For over 50 years patients with liver cirrhosis were considered to be at markedly increased risk of bleeding. This dogma was seemingly supported by abnormalities in standard laboratory tests (SLTs), such as the prothrombin time, that were interpreted as indicating a bleeding diathesis. However, publications from the last decade have revealed SLTs to be poor predictors of bleeding and it is now understood that stable patients with cirrhosis have a rebalanced haemostatic system and preserved thrombin generation...

INTRODUCTION: Resuscitation strategies following blunt trauma have been linked to immuno-inflammatory complications leading to systemic inflammatory syndrome (SIRS), sepsis and multiple organ failure (MOF). The effect of resuscitation strategy on longitudinal inflammation marker trajectories is, however, unknown. We hypothesized that the effect of resuscitation strategy extends beyond the trauma-related coagulopathy, perhaps affecting the longitudinal immuno-inflammatory response to injury...
