Exploratory Assessment of Manufactured E-Liquids and Do It Yourself (DIY) E-Liquids

Introduction: Electronic Nicotine Delivery Systems (ENDS) debuted in 2006 within the U.S market as novel tobacco products and have been gaining popularity since. Without enforced regulations, prevalence of awareness and use has significantly increased. The purpose of this study is to explore the evolving landscape of ENDS using the Host, Agent, Vector, Environment (HAVE) model with a focus on manufactured e-liquids and do it yourself (DIY) e-liquids as the Agent. Methods: Content analysis of e-cigarette web forums was conducted to identify popular brick and mortar point of sales (POS) for the purchase of ENDS products. POS were mapped out within a 1-, 2-, and 3- mile radius from three college campuses using Google Maps. An environmental scan was then conducted on randomly selected POS sites (N=17) where observations on e-liquid flavors and characteristics were identified. In addition, a content analysis of web forums was used to qualitatively characterize DIY e-liquids in depth. Results: A total of 602 flavors were profiled in the POS environmental scans and five main flavor categories of e-liquids were identified: 1) Tobacco and Menthol (16.6%); 2) Desserts and Candies (16.6%); 3) Fruits (20.6%); 4) Drinks (10.1%); 5) Other (36.0%). Most flavored e-liquids were sold in stand-alone vials (91.0%). When sold with manufactured products, flavored e-liquids were sold in E-Hookahs (10.6%) compared to E-Cigarettes (4.7%). Most (96.8%) flavored e-liquids were available with and without nicotine. Based on content analysis of e-cigarette web forums, the words with the highest frequency in the DIY transcripts were: “flavor”, “mixing”, “liquid”, “calculators”, and “nicotine”. Conclusions: Our findings indicate that for both manufactured and DIY e-liquids, flavors are a distinguishing and primary characteristic. Given these findings, increased surveillance efforts to monitor ENDS and e-liquids are necessary to inform regulatory science

Iliorenal periscope graft to maintain blood flow to accessory renal artery

Parallel endografts such as “chimney” and “periscope” are being increasingly used to maintain blood flow to visceral and supra-aortic branches in patients with different aortic disorders. We present a new technique, “iliorenal periscope graft”, in a patient with abdominal aortic aneurysm undergoing endovascular aortic repair. In this case, left accessory renal artery flows were provided by an iliorenal periscope graft that extends from the left accessory renal artery to the right common iliac artery in a retrograde fashion

The Annual Trends between Neurointerventional and Neurosurgical Procedures in Korea: Analysis using HIRA Data from 2010 to 2016

PURPOSE: The purpose of this study was to evaluate the annual trend for several neurosurgical and neurointerventional procedures (NIPs) in Korea between 2010 and 2016 by using medical claim data. MATERIALS AND METHODS: All data during the recent 7 years were collected from Bigdata Hub provided by the Health Insurance Review & Assessment Service (HIRA). Using several codes for medical practice, we estimated the number of in-patients for each practice and calculated the annual variation of each procedure. These data were compared between each NIP versus the equivalent surgical procedure and analyzed according to the geographic distribution and the hospital grade. RESULTS: During the past 7 years, the average growth rate of all stroke in-patients is 2.05%, and the number of in-patients with ischemic stroke is 5.2 times higher than those with hemorrhagic stroke. While clipping accounted for 53.7% (5,209/9,700) of total patients in 2010, 61.9% of patients (9,146/14,781) are currently undergoing coiling procedure in 2016. MT for acute ischemic stroke has grown annually by an average of 35.9% during the past 3 years. Stenting and angioplasty for carotid artery and intracranial artery showed relatively stable growth during the past 7 years. Especially, carotid artery stenting is rapidly increasing in secondary general hospitals, where more than 50% of these procedures were performed after 2014. CONCLUSION: In this study, we found that most of NIPs has increased annually over the past 7 years and that NIPs are rapidly replacing conventional surgical maneuvers in Korea.ope
