The Mean

SummaryVitamin K status was evaluated using coagulation studies and/ or vitamin IQ assays in a total of 53 normal fetuses and 47 neonates. Second trimester fetal blood samples were obtained for prenatal diagnosis under ultrasound guidance. Endogenous vitamin K1 concentrations (determined by high performance liquid chromatography) were substantially lower than maternal levels. The mean maternal-fetal gradient was 14-fold at mid trimester and 18-fold at birth. Despite low vitamin K levels, descarboxy prothrombin, detected by a staphylocoagulase assay, was elevated in only a single fetus and a single neonate.After maternal oral supplementation with vitamin K1, cord vitamin K1 levels were boosted 30-fold at mid trimester and 60 fold at term, demonstrating placental transfer. However, these levels were substantially lower than corresponding supplemented maternal levels. Despite elevated vitamin K1 concentrations, supplemented fetuses and neonates showed no increase in total or coagulant prothrombin activity. These results suggest that the low prothrombin levels found during intrauterine life are not due to vitamin K deficiency.

Endovascular Balloon Occlusion

ABSTRACT Introduction:  The introduction of low profile devices designed for Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) after trauma has the potential to change practice, outcomes and complication profiles related to this procedure. Methods: The AAST Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery (AORTA) registry was utilized to identify REBOA patients from 16 centers -comparing presentation, intervention and outcome variables for those REBOA via traditional 11-12 access platforms and trauma-specific devices requiring only 7 F access. Results:From Nov 2013-Dec 2017, 242 patients with completed data were identified, constituting 124 7F and 118 11-12F uses. Demographics of presentation were not different between the two groups, except that the 7F patients had a higher mean ISS (39.2 34.1, p = 0.028). 7F device use was associated with a lower cut-down requirement for access (22.6% vs. 37.3%, p = 0.049) and increased ultrasound guidance utilization (29.0% 23.7%, p = 0.049). 7F device afforded earlier aortic occlusion in the course of resuscitation (median 25.0 mins vs. 30 mins, p = 0.010), and had lower median PRBC (10.0 vs. 15.5 units, p = 0.006) and FFP requirements (7.5 vs. 14.0 units, p = 0.005). 7F patients were more likely to survive 24 hrs (58.1% vs. 42.4%, p = 0.015) and less likely to suffer in-hospital mortality (57.3% vs. 75.4%, p = 0.003). Finally, 7F device use was associated with a 4X lower rate of distal extremity embolism (20.0% vs. 5.6%, p = 0.014;OR 95% CI 4.25 [1.25-14.45]) compared to 11-12F counterparts. Conclusion: The introduction of trauma specific 7F REBOA devices appears to have influenced REBOA practices, with earlier utilization in severely injured hypotensive patients via less invasive means that are associated with lower transfusion requirements fewer thrombotic complications and improved survival. Additional study is required to determine optimal REBOA utilization.

The results of 205 puncture biopsies of solid and cystic pancreatic lesions performed in 202 patients at the Republican Oncological Dispensary of the Republic of Karelia for a 7-year period (2009-2015) are presented. Informative material for morphological investigation was obtained in 95.5% of cases. A comparison of results of cytological examination of the material from 56 patients with pancreatic lesions with histological data was carried out. The efficiency of the cytological method was 90.6%, sensitivity - 87.8%, specificity - 100%. To determine histological form of tumor in cytological examination of the material of the pancreas was successful in 82.1% of cases.
