  • Protocolized use of Factor Eight Inhibitor Bypassing Activity (FEIBA) for the reversal of warfarin induced coagulopathy AMERICAN JOURNAL OF EMERGENCY MEDICINE Htet, N. N., Barounis, D., Knight, C., Umunna, B., Hormese, M., Lovell, E. 2020; 38 (3): 539-544


    Coagulopathy due to warfarin in patients with major bleeding was traditionally reversed with fresh frozen plasma and intravenous (IV) vitamin K, but prothrombin complex concentrates (PCC) are increasingly used in the treatment of these patients. Factor Eight Inhibitor Bypassing Activity (FEIBA) is an activated four-factor PCC most commonly used in patients with hemophilia. We aimed to evaluate the efficacy and safety of FEIBA and IV vitamin K for the reversal of warfarin-associated coagulopathy in patients with major bleeding, by measuring the percentage of patients who achieved target INR ≤ 1.5 and the incidence of thrombotic adverse events (TAE).In this prospective observational study, we enrolled patients presenting to the Emergency Department (ED) with warfarin associated coagulopathy (INR > 1.5) and major bleeding. Patients received FEIBA using an INR based dosing strategy and IV vitamin K.In 43 patients, median initial INR was 4.0 (2.7, 7.3 interquartile range (IQR)). Median time to result the second INR was 45 min (38, 55 IQR) and the median INR was 1.4 (1.3, 1.6 IQR). Out of the 43 patients, 93% achieved the target INR of ≤1.5. In-hospital mortality was 40% (17 patients). There were 11 TAEs in 6 patients (14%); 4 events in 2 patients (5%) were attributed to FEIBA.A protocolized use of FEIBA and IV vitamin K resulted in the efficacious reversal of warfarin-induced coagulopathy in patients with major bleeding. TAEs occurred in 14% of patients and were attributed to FEIBA in 5% of patients.

  • Critical Care Education Day: A Novel, Multidisciplinary, and Interactive Critical Care Education Session for Emergency Medicine Residents. Cureus Htet, N. N., Gordon, A. J., Mitarai, T. 2020; 12 (1): e6785


    Critical care medicine (CCM) is central to emergency medicine (EM) resident education. We feel that the traditional lecture format is not the ideal way to teach EM critical care, which requires integration and prioritization of diagnostic workup and team-based resuscitation under time pressure. We describe a novel critical care education day where an interactive, practical, and multidisciplinary critical care educational experience was provided for EM residents using case-based small-group sessions and fast-paced simulation.

  • Acute Respiratory Distress Syndrome: Etiology, Pathogenesis, and Summary on Management. Journal of intensive care medicine Kaku, S., Nguyen, C. D., Htet, N. N., Tutera, D., Barr, J., Paintal, H. S., Kuschner, W. G. 2019: 885066619855021


    The acute respiratory distress syndrome (ARDS) has multiple causes and is characterized by acute lung inflammation and increased pulmonary vascular permeability, leading to hypoxemic respiratory failure and bilateral pulmonary radiographic opacities. The acute respiratory distress syndrome is associated with substantial morbidity and mortality, and effective treatment strategies are limited. This review presents the current state of the literature regarding the etiology, pathogenesis, and management strategies for ARDS.

  • Needle-guided ultrasound technique for axillary artery catheter placement in critically ill patients: A case series and technique description. Journal of critical care Htet, N., Vaughn, J., Adigopula, S., Hennessey, E., Mihm, F. 2017; 41: 194-197


    Axillary arterial cannulation for blood pressure monitoring has been reported in adults since 1973. Reported failure rates using palpation landmarks are high. This report describes a needle-guided ultrasound technique for axillary arterial line placement in critically ill patients.A retrospective review of all patients requiring axillary arterial cannulation attempts with ultrasound-assisted needle guidance for hemodynamic monitoring was performed from July 2010 to June 2016 at a single institution.One hundred fifty nine (159) cannulation attempts were performed in 155 patients. The overall success rate was 97%, with a first pass success rate of 84%. Inexperienced operators performed 49% of procedures under direct faculty supervision, and had a 99% success rate, which was not different from experienced operators. Almost 20% of patients had moderate-to-severe coagulopathy (platelets<50k/uL, INR>2.0 or PTT>60s). Complications reported included the following: nonfunctioning of catheter (6%) and hematoma (6%). Ischemia was noted in 2 patients (1%), but only one was attributed to the arterial catheter.Use of the needle-guided ultrasound assisted approach for axillary arterial line placement is easily teachable and can be used to promote safe and successful placement of axillary arterial lines for novice learners.

  • Biodistribution and predictive value of (IF)-I-18-fluorocyclophosphamide in mice bearing human breast cancer xenografts JOURNAL OF NUCLEAR MEDICINE Kesner, A. L., Hsueh, W., Htet, N. L., Pio, B. S., Czernin, J., Pegram, M. D., Phelps, M. E., Silverman, D. H. 2007; 48 (12): 2021-2027


    In mice bearing human breast cancer xenografts, we examined the biodistribution of (18)F-fluorocyclophosphamide ((18)F-F-CP) to evaluate its potential as a noninvasive prognostic tool for predicting the resistance of tumors to cyclophosphamide therapy.(18)F-F-CP was synthesized as we recently described, and PET data were acquired after administration of (18)F-F-CP in mice bearing human breast cancer xenografts (MCF-7 cells). Tracer biodistribution in reconstructed images was quantified by region-of-interest analysis. Distribution was also assessed by harvesting dissected organs, tumors, and blood, determining (18)F content in each tissue with a gamma-well counter. The mice were subsequently treated with cyclophosphamide, and tumor size was monitored for at least 3 wk after chemotherapy administration.The distribution of harvested activity correlated strongly with distribution observed in PET images. Target organs were related to routes of metabolism and excretion. (18)F-F-CP uptake was highest in kidneys, lowest in brain, and intermediate in tumors, as determined by both image-based and tissue-based measurements. (18)F-F-CP uptake was not inhibited by coadministration of an approximately x700 concentration of unlabeled cyclophosphamide. PET measures of (18)F-F-CP uptake in tumor predicted the magnitude of the response to subsequent administration of cyclophosphamide.Noninvasive assessment of (18)F-F-CP uptake using PET may potentially be helpful for predicting the response of breast tumors to cyclophosphamide before therapy begins.
