In Korean epileptics, there was no significant relationship between three known SNPs in MDR1 and drug resistance. And there was no association of MDR1 haplotype based on above three sites with pharmacoresistance.
Adult advanced life support (ALS) is an important part of the chain of survival, promoting systemic circulation and oxygen supply during high-quality basic life support in patients with cardiac arrest. It includes advanced airway management, manual defibrillation, pharmacological therapy with vasopressors and antiarrhythmic agents, use of an extracorporeal circulation device, and other techniques to achieve return of spontaneous circulation (ROSC). [1][2][3] Several milestone studies on ALS have been published since the publication of the 2015 Korean cardiopulmonary resuscitation (CPR) guidelines. These include a multicenter, randomized, double-blind, placebo-controlled study evaluating the effect of epinephrine in patients with out-ofhospital cardiac arrest (OHCA) as well as a comparative study on amiodarone, lidocaine, or placebo in patients with refractory shockable rhythm. 4,5 A study comparing the use of a supraglottic airway (SGA) device and endotracheal intubation for advanced airway management during OHCA S27
Recent evidence has demonstrated the survival benefits of helicopter transport for trauma patients. The purpose of this study was to evaluate the effectiveness of hospital-based helicopter emergency medical services (H-HEMS) in comparison with ground ambulance transport in improving mortality outcomes in patients with major trauma. Study participants were divided into 2 groups according to type of transport to the trauma center; that is, either via ground emergency medical services (GEMS) or via H-HEMS. The study was conducted from October 2013 to July 2015. Mortality outcomes in the H-HEMS group were compared with those in the GEMS group by using the Trauma and Injury Severity Score (TRISS) analysis. The number of participants finally included in the study was 312. Among these patients, 63 were adult major trauma patients transported via H-HEMS, and 47.6% were involved in traffic accidents. For interhospital transport, the Z and W statistics revealed significantly higher scores in the H-HEMS group than in the GEMS group (Z statistic, 2.02 vs. 1.16; P = 0.043 vs. 0.246; W statistic, 8.87 vs. 2.85), and 6.02 more patients could be saved per 100 patients when H-HEMS was used for transportation. TRISS analysis revealed that the use of H-HEMS for transporting adult major trauma patients was associated with significantly improved survival compared to the use of GEMS.
Background Calcium level is associated with sudden cardiac death based on several cohort studies. However, there is limited evidence on the association between ionized calcium, active form of calcium, and resuscitation outcome. This study aimed to evaluate the potential role of ionized calcium in predicting resuscitation outcome in patients with out-of-hospital cardiac arrest. Methods We analyzed the Korean Cardiac Arrest Research Consortium data (KoCARC) registry, a web-based multicenter registry that included 65 participating hospitals throughout the Republic of Korea. The patients with out-of-hospital cardiac arrest over 19 years old and acquired laboratory data including calcium, ionized calcium, potassium, phosphorus, creatinine, albumin at emergency department (ED) arrival were included. The primary outcome was successful rate of return of spontaneous circulation (ROSC) and the secondary outcomes were survival hospital discharge and favorable neurological outcome (cerebral performance category 1 or 2) at hospital discharge. Results Eight-hundred and eighty-three patients were enrolled in the final analysis and 448 cases (54%) had ROSC. In multivariable logistic regression analysis, ionized calcium level was associated with ROSC (odds ratio, 1.77; 95% CI1.28-2.45; p = 0.001) even though calcium
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.
