Objectives: To characterize contemporary use of tranexamic acid (TXA) in combat injury and to assess the effect its administration on total blood product use, thromboembolic complications, mortality.Design: Retrospective observational study comparing TXA with no patients receiving at least 1 unit packed red cells.A subgroup massive transfusion (Ն10 units cells) was also examined.Univariate multivariate regression analyses were used identify parameters associated survival.Kaplan-Meier life...
A three-stage genome-wide association study recently identified single nucleotide polymorphisms (SNPs) in five loci (fibroblast growth receptor 2 (FGFR2), trinucleotide repeat containing 9 (TNRC9), mitogen-activated protein kinase 3 K1 (MAP3K1), 8q24, and lymphocyte-specific 1 (LSP1)) associated with breast cancer risk. We investigated whether the associations between these SNPs risk varied by clinically important tumor characteristics up to 23,039 invasive cases 26,273 controls from 20...
Recent studies based on genome-wide association, linkage, and admixture scan analysis have reported associations of various genetic variants in 8q24 with susceptibility to breast, prostate, colorectal cancer. This locus lies within a 1.18-Mb region that contains no known genes but is bounded at its centromeric end by FAM84B telomeric c-MYC, two candidate cancer genes. To investigate the specific loci cancers, we genotyped nine previously cancer-associated single-nucleotide polymorphisms...
Bleeding is the most common cause of preventable death after trauma.
To quantify the impact of fibrinogen-containing cryoprecipitate in addition to antifibrinolytic tranexamic acid on survival combat injured.Retrospective observational study comparing mortality 4 groups: only, and cryoprecipitate, neither nor cryoprecipitate. balance comparisons, propensity scores were developed added as covariates logistic regression models predicting mortality.A Role 3 Combat Surgical Hospital southern Afghanistan.A total 1332 patients identified from prospectively...
The considerable uncertainty regarding cancer risks associated with inherited mutations of BRCA2 is due to unknown factors. To investigate whether common genetic variants modify penetrance for mutation carriers, we undertook a two-staged genome-wide association study in carriers. In stage 1 using the Affymetrix 6.0 platform, 592,163 filtered SNPs genotyped were available on 899 young (<40 years) affected and 804 unaffected carriers European ancestry. Associations evaluated survival-based...
The objective of this study is to characterize modern point-of-injury (POI) en-route care platforms and compare mortality among casualties evacuated with conventional military retrieval (CMR) methods those an advanced medical (AMR) capability.Following a decade war in Afghanistan, the impact capabilities from POI on unknown.Casualties one level III facility Afghanistan (July 2008-March 2012) were identified UK US trauma registries. Groups comprised by medically qualified provider-led, AMR...
