Only a minority of heavy drinkers progress to alcohol-related cirrhosis (ALC). The aim of this study was to identify common genetic variants that underlie risk for ALC. We analyzed data from 1,128 subjects of European ancestry with ALC and 614 heavy drinking subjects without known liver disease from Australia, the United States, the United Kingdom and three countries in Europe. Genome-wide association study (GWAS) was performed, adjusting for principal components and clinical covariates (alcohol use, age, sex, BMI, diabetes). We validated our GWAS findings using UK Biobank. We then performed a meta-analysis combining data from our study, the UK Biobank, and a previously published GWAS. Our GWAS found genome-wide significant risk association of rs738409 in PNPLA3 (Odds Ratio (OR)=2.19 (G allele), p-value=4.93x10-17 ) and rs4607179 near HSD17B13 (OR=0.57 (C allele), p-value=1.09x10-10 ) with ALC. Conditional analysis accounting for the PNPLA3 and HSD17B13 loci identified a new protective association at rs374702773 in Fas Associated Factor family member 2 (FAF2) (OR=0.61 (del(T) allele), p-value=2.56x10-8 ) for ALC. This association was replicated in the UK Biobank using conditional analysis (OR=0.79, p-value=0.001). check details Meta-analysis (without conditioning) confirmed genome-wide significance for the newly identified FAF2 locus as well as PNPLA3 and HSD17B13. Two other previously known loci (SERPINA1, SUGP1/TM6SF2) were also genome-wide significant in the meta-analysis. GeneOntology pathway analysis identified lipid droplets as the target for several identified genes. In conclusion, our GWAS identified a new locus at FAF2 associated with reduced risk of ALC among heavy drinkers. Like the PNPLA3 and HSD17B13 gene products, the FAF2 product has been localized to fat droplets in hepatocytes. Our genetic findings implicate lipid droplets in the biological pathway(s) underlying ALC.
Retrospective chart review to assess the effectiveness of an institutional intravenous (IV) dihydroergotamine (DHE) therapy protocol for refractory migraine in the pediatric population.

Limited high-quality evidence exists to guide the approach to treatment of refractory migraine with IV DHE, particularly in the pediatric population. This study reviews our institutional experience in implementing an IV DHE protocol in children to identify areas for improvement. We specifically sought to determine whether the outcome differed at follow-up between children who completed the full course of DHE (8 or 9 doses) as specified in our institutional protocol and those who did not. In addition, given the limited Food and Drug Administration-approved treatments for chronic migraine (CM) in the pediatric population, re-evaluating the response rate in this group of patients was of particular interest.

A retrospective cohort based on a chart review of 159 consecutive pediatric patients who received IV DHE while inpatiee full course of DHE. In our cohort, there was no difference in pain relief at follow-up between patients who completed the full 8 or 9 doses of DHE and those that did not. Discontinuing DHE once the patient has achieved headache freedom would therefore achieve the therapeutic goal while shortening the hospital stay. To potentially impact longer term pain relief, incorporation of a comprehensive treatment approach into the IV DHE admission is of interest for future study and quality improvement initiatives.To optimize diagnostic workup of the current severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic, we systematically reviewed neurological and neuroradiological manifestations of SARS-CoV-2 and all other known human coronavirus species (HCoV). Which lessons can we learn? We identified relevant publications (until 26 July 2020) using systematic searches in PubMed, Web of Science, and Ovid EMBASE with predefined search strings. A total of 4571 unique publications were retrieved, out of which 378 publications were selected for in-depth analysis by two raters, including a total of 17549 (out of which were 14418 SARS-CoV-2) patients. Neurological complications and associated neuroradiological manifestations are prevalent for all HCoVs (HCoV-229E, HKU1, NL63, OC43, Middle East respiratory syndrome (MERS)-CoV, SARS-CoV-1, and SARS-CoV-2). Moreover there are similarities in symptomatology across different HCoVs, particularly between SARS-CoV-1 and SARS-CoV-2. Common neurological manifestations include fatigue, headache, and smell/taste disorders. Additionally, clinicians need to be attentive for at least five classes of neurological complications (1) Cerebrovascular disorders including ischemic stroke and macro/micro-hemorrhages, (2) encephalopathies, (3) para-/postinfectious immune-mediated complications such as Guillain-Barré syndrome and acute disseminated encephalomyelitis, (4) (meningo-)encephalitis, potentially with concomitant seizures, and (5) neuropsychiatric complications such as psychosis and mood disorders. Our systematic review highlights the need for vigilance regarding neurological complications in patients infected by SARS-CoV-2 and other HCoVs, especially since some complications may result in chronic disability. Neuroimaging protocols should be designed to specifically screen for these complications. Therefore, we propose practical imaging guidelines to facilitate the diagnostic workup and monitoring of patients infected with HCoVs.West Nile virus (WNV) is a mosquito-borne emerging virus in Europe with capacity to cause neurological complications such as encephalitis or meningoencephalitis in humans, birds or equids. In Spain, WNV is actively circulating in mosquitoes, birds and horses in different regions, but never has been deeply studied in Extremadura. Therefore, the aim of this study was to evaluate the seroprevalence of WNV in equids of those areas and to analyse the risk factors associated with exposure to the virus. A total of 199 out of 725 equids presented antibodies against WNV by competition ELISA (27.45%), while 22 were doubtful (3.03%). Anti-WNV IgM antibodies were detected in 16 equids (2.21%), and 3 animals were doubtful (0.41%). All ELISA-reactive positive/doubtful sera (N = 226) were further tested by micro-virus neutralization test (VNT), and a total of 143 horses were confirmed as positive for WNV, obtaining a seroprevalence of 19.72% in equids of western Spain. In addition, specific antibodies against USUV were confirmed in 11 equids.
