More than a third of patients referred for primary PCI from the emergency department did not have a STEMI. Multiple patient-level characteristics were significantly associated with an increased odds of false-positive STEMI activation.
The aim was to review the pregnancy and obstetric outcome in women with factor VII (FVII) deficiency. The study group contained women with FVII deficiency, registered with Haemophilia centre and Haemostasis Unit at the Royal Free Hospital, London. The women were interviewed and case notes were reviewed. The main outcome measures were changes in FVII levels in pregnancy, maternal and perinatal outcome. The FVII levels ranged from 7-36 IU dL(-1) in the 13 women included in the study. There were a total of 14 pregnancies in seven women. Ten pregnancies in four women were prior to the diagnosis of FVII deficiency. Following the diagnosis of FVII deficiency, there were four pregnancies in three women. There was an increase in the FVII level during pregnancy in these women from a mean baseline level of 33 IU dL(-1) to a mean of 73 IU dL(-1). These women received recombinant FVIIa replacement during labour and delivery. There were two early pregnancy losses, both associated with excessive haemorrhage. There was only one postpartum haemorrhage in the study. There is a significant increase in FVII levels in pregnancy in women with heterozygous FVII deficiency. The risk of bleeding in early pregnancy might be higher than that at term, due to inadequate rise in the FVII level in early pregnancy.
Xylans in the cell walls of monocots are structurally diverse. Arabinofuranose-containing glucuronoxylans are characteristic of commelinids. However, other structural features are not correlated with the major transitions in monocot evolution. Most studies of xylan structure in monocot cell walls have emphasized members of the Poaceae (grasses). Thus, there is a paucity of information regarding xylan structure in other commelinid and in non-commelinid monocot walls. Here, we describe the major structural features of the xylans produced by plants selected from ten of the twelve monocot orders. Glucuronoxylans comparable to eudicot secondary wall glucuronoxylans are abundant in non-commelinid walls. However, the α-D-glucuronic acid/4-O-methyl-α-D-glucuronic acid is often substituted at O-2 by an α-L-arabinopyranose residue in Alismatales and Asparagales glucuronoxylans. Glucuronoarabinoxylans were the only xylans detected in the cell walls of five different members of the Poaceae family (grasses). By contrast, both glucuronoxylan and glucuronoarabinoxylan are formed by the Zingiberales and Commelinales (commelinids). At least one species of each monocot order, including the Poales, forms xylan with the reducing end sequence -4)-β-D-Xylp-(1,3)-α-L-Rhap-(1,2)-α-D-GalpA-(1,4)-D-Xyl first identified in eudicot and gymnosperm glucuronoxylans. This sequence was not discernible in the arabinopyranose-containing glucuronoxylans of the Alismatales and Asparagales or the glucuronoarabinoxylans of the Poaceae. Rather, our data provide additional evidence that in Poaceae glucuronoarabinoxylan, the reducing end xylose residue is often substituted at O-2 with 4-O-methyl glucuronic acid or at O-3 with arabinofuranose. The variations in xylan structure and their implications for the evolution and biosynthesis of monocot cell walls are discussed.
Women with factor VII deficiency exhibit a spectrum of bleeding symptoms, menorrhagia being one of the commonest symptoms. This has adverse effect on their quality of life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
