Background Obstetrical hemorrhage is a leading cause of morbidity and mortality, yet is inconsistently defined. In 2014, the American Congress of Obstetricians and Gynecologists (ACOG) reVITALize program redefined postpartum hemorrhage (PPH) as greater than 1,000 mL blood loss regardless of the mode of delivery (MOD). Objective We sought to assess the reVITALize definition's validity by understanding whether the definition of PPH should, as proposed by ACOG, be one value regardless of MOD. Study Design This is a retrospective study of all women who delivered at the hospital of the University of Pennsylvania from October 15, 2013 through December 15, 2013...

Management of factor XI (FXI) deficiency in pregnancy is complicated by lack of correlation between FXI level and bleeding risk. Clinicians should be vigilant about the potential for prolonged or excessive bleeding following miscarriage or termination of pregnancy, or postpartum hemorrhage (PPH). A multidisciplinary approach along with an individual care plan is recommended to prevent bleeding complications. Assessment of bleeding history, FXI level, and global tests of hemostasis can aid management decisions regarding hemostatic prophylaxis...

BACKGROUND: Biogenic amines (BAs) are produced by the enzymatic decarboxylation of amino acids, and are well-known for their toxicity to humans. This study describes a new method using microbial transglutaminase (MTGase) to covalently link BAs such as histamine (HIS) and tyramine (TYR) to the glutamine residues of alcalase-hydrolyzed pea protein (PPH). RESULTS: The incubation of PPH and HIS and TYR in the presence of MTGase at 37 °C led to the formation of conjugates, as determined by liquid chromatography, after derivatization with dansyl chloride...

BACKGROUND: Diastolic pulmonary gradient (DPG), calculated as the difference between pulmonary artery diastolic pressure and mean pulmonary capillary wedge pressure ≥ 7 mmHg is associated with pulmonary vascular disease and portends poor prognosis in heart failure (HF). The prognostic relevance of DPG in group 1 pulmonary hypertension (PH) is uncertain. METHODS: Using the Pulmonary Hypertension Connection (PHC) risk equation for 225 patients in the NIH-PPH, the 5-year probability of death was calculated, which was then compared with DPG using a Cox proportional hazards model...

OBJECTIVE: To identify risk factors for post-partum hemorrhage (PPH) following vacuum assisted vaginal delivery (VAVD). STUDY DESIGN: A retrospective study of all women with singleton pregnancies who underwent VAVD in a tertiary hospital (2012-2014). PPH was defined as any of the following: ≥500 ml estimated blood loss, hemoglobin drop ≥3 g/dl (difference between pre- and post-VAVD hemoglobin levels) or the need for blood products transfusion. Characteristics of women with PPH following VAVD were compared to those of women with no PPH following VAVD...

Hybrid rice is the dominant form of rice planted in China, and its use has extended worldwide since the 1970s. It offers great yield advantages and has contributed greatly to the world's food security. However, the molecular mechanisms underlying heterosis have remained a mystery. In this study we integrated genetics and omics analyses to determine the candidate genes for yield heterosis in a model two-line rice hybrid system, Liang-you-pei 9 (LYP9) and its parents. Phenomics study revealed that the better parent heterosis (BPH) of yield in hybrid is not ascribed to BPH of all the yield components but is specific to the BPH of spikelet number per panicle (SPP) and paternal parent heterosis (PPH) of effective panicle number (EPN)...

INTRODUCTION: There is an increasing number of forced migrants globally, including refugees, asylum seekers, internally displaced persons and undocumented migrants. According to international law, forced migrants should enjoy access to health services free of discrimination equivalent to the host population, but they face barriers to healthcare worldwide. This may lead to a delay in care and result in preventable hospital treatment, referred to as potentially preventable hospitalisation (PPH) or ambulatory care sensitive hospitalisation (ACSH)...

BACKGROUND: Post-partum haemorrhage (PPH) is a major cause of maternal mortality globally. Tranexamic acid, an anti-fibrinolytic agent, is a novel approach in an attempt to prevent this dreadful complication. This study aims to document the efficacy of intravenous (IV) tranexamic acid in reducing blood loss during and after caesarean section (CS). METHODS: In this prospective randomised placebo-controlled open-label study, 100 mothers scheduled for elective CS were randomly selected and divided into two groups (study and control) of 50 each...

INTRODUCTION: Conventionally postpartum hemorrhage (PPH) has been defined as blood loss of more than 500 ml following vaginal delivery and 1000 ml following a cesarean section [Pritchard et al. in Am J Obstet Gynecol 84(10):1271-1282, (1962)]. Another definition labels PPH as any blood loss which causes a 10 % drop in hematocrit [Combs et al. in Obstet Gynecol 77:69-76, (1991)] or which threatens the hemodynamic stability of the patient and necessitates blood transfusion [Prendiville et al...

Evidence about relationship between antidepressant use during pregnancy and the risk of postpartum hemorrhage (PPH) is conflicting. The aim of this meta-analysis was to systematically assess this relationship. To identify relevant studies, we conducted systematic searches in PubMed and Embase of articles published through May 2016. Random-effects models were adopted to estimate overall relative risk. In total, eight studies involving more than 40,000 PPH cases were included in our meta-analysis. After pooling the estimates, the odds for developing PPH were 1...

BACKGROUND: Postpartum hemorrhage (PPH) is a leading cause of obstetric morbidity. There is limited understanding of patients' knowledge about blood loss at delivery, PPH, and PPH-related morbidities, including transfusion and anemia. METHODS: We surveyed 100 healthy postpartum patients who underwent vaginal or cesarean delivery about blood loss, and whether they received information about transfusion and peripartum hemoglobin (Hb) testing. Responses were compared between women undergoing vaginal delivery vs...

Evidence exists for titration of intravenous oxytocin during induction and augmentation, whereas no evidence was identified for titration of intravenous oxytocin following vaginal birth, where management excluded oxytocin for postpartum haemorrhage (PPH). This retrospective cohort study explored this issue through patient case notes and computerised perinatal data. Analysis included 335 women comparing induction (n = 226, 67%) to augmentation (n = 109, 33%). The two groups differed in terms of: parity; oxytocin dosage; length of time on intravenous oxytocin; and the length of first and second stage labour...

Pure parsimony haplotyping (PPH) problem is important in bioinformatics because rational haplotyping inference plays important roles in analysis of genetic data, mapping complex genetic diseases such as Alzheimer's disease, heart disorders and etc. Haplotypes and genotypes are m-length sequences. Although several integer programing models have already been presented for PPH problem, its NP-hardness characteristic resulted in ineffectiveness of those models facing the real instances especially instances with many heterozygous sites...
