Background And Objectives: Epilepsy education has been transformed over the past 2 decades, leading to a need for structured formative assessment tools. The American Epilepsy Society developed the Epilepsy Fellowship In-Training Examination (EpiFITE) to provide high-quality formative assessment for fellows, to stimulate program improvement, and to guide future learning and teaching. The aim of this study was to explore validity evidence for the EpiFITE in meeting these goals.

Article Synopsis
  • The study investigates the genetic basis of supraventricular tachycardias, focusing on atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular accessory pathways/reciprocating tachycardia (AVAP/AVRT).
  • Through multiancestry meta-analyses of genome-wide association studies, researchers identified significant genetic loci associated with AVNRT and AVAP/AVRT, implicating specific genes in these cardiac conditions.
  • The results suggest that gene regions related to ion channels and cardiac development play crucial roles in susceptibility to supraventricular tachycardias, potentially influencing other cardiovascular issues such as atrial fibrillation

Multiancestry Genome-Wide Association Study of Aortic Stenosis Identifies Multiple Novel Loci in the Million Veteran Program.

Circulation

March 2023

Cardiovascular Medicine Division, Department of Medicine, Brigham and Women's Hospital (A.M.S., C.J.O.), Harvard Medical School, Boston, MA.

Background: Calcific aortic stenosis (CAS) is the most common valvular heart disease in older adults and has no effective preventive therapies. Genome-wide association studies (GWAS) can identify genes influencing disease and may help prioritize therapeutic targets for CAS.

Methods: We performed a GWAS and gene association study of 14 451 patients with CAS and 398 544 controls in the Million Veteran Program.

Kristen H. Arredondo is currently at the Department of Neurology, Dell Medical School, The University of Texas at Austin, TX.

Background And Objective: Nearly one-third of persons with epilepsy will continue having seizures despite trialing multiple antiseizure medications. Epilepsy surgery may be beneficial in these cases, and evaluation at a comprehensive epilepsy center is recommended. Numerous palliative and potentially curative approaches exist, and types of surgery performed may be influenced by center characteristics.

Monogenic and Polygenic Contributions to QTc Prolongation in the Population.

Cardiovascular Disease Initiative (V.N., V.N.M., S.J.J., S.H.C., L.-C.W., J.L.H., P.T.E., S.A.L.), Broad Institute, Cambridge, MA.

Background: Rare sequence variation in genes underlying cardiac repolarization and common polygenic variation influence QT interval duration. However, current clinical genetic testing of individuals with unexplained QT prolongation is restricted to examination of monogenic rare variants. The recent emergence of large-scale biorepositories with sequence data enables examination of the joint contribution of rare and common variations to the QT interval in the population.

Department of Neurology (M.E.R., A.M., L.C.W., B.B.T., C.S., L.A.D., R.N.J., K.L.F.), Brown University, Alpert Medical School, Providence, RI.

Article Synopsis
  • * In a study of 590 ICH patients, 59% developed delirium, with older age and higher severity of ICH being risk factors, while younger age helped predict resolution of delirium in 75% of cases.
  • * Results showed that persistent delirium significantly increased the odds of unfavorable outcomes compared to resolved delirium, and the site of postacute care (like inpatient rehab versus skilled nursing) played a role in mediating these effects, reducing the impact of delirium by 25%.

Rare Coding Variants Associated With Electrocardiographic Intervals Identify Monogenic Arrhythmia Susceptibility Genes: A Multi-Ancestry Analysis.

Program in Medical and Population Genetics and Cardiovascular Disease Initiative, Broad Institute of MIT and Harvard, Cambridge, MA (S.H.C., S.J.J., A.W.H., J.L.H., V.N.M., L.-C.W., M.D.C., C.J.-Y.L., H.L.R., C.R., P.T.E., S.A.L.).

Background: Alterations in electrocardiographic (ECG) intervals are well-known markers for arrhythmia and sudden cardiac death (SCD) risk. While the genetics of arrhythmia syndromes have been studied, relations between electrocardiographic intervals and rare genetic variation at a population level are poorly understood.

Methods: Using a discovery sample of 29 000 individuals with whole-genome sequencing from Trans-Omics in Precision Medicine and replication in nearly 100 000 with whole-exome sequencing from the UK Biobank and MyCode, we examined associations between low-frequency and rare coding variants with 5 routinely measured electrocardiographic traits (RR, P-wave, PR, and QRS intervals and corrected QT interval).

Background: The P-wave duration (PWD) is an electrocardiographic measurement that represents cardiac conduction in the atria. Shortened or prolonged PWD is associated with atrial fibrillation (AF). We used exome-chip data to examine the associations between common and rare variants with PWD.

Objective: To examine whether sustained minimal manifestation status (MMS) with complete withdrawal of prednisone is better achieved in thymectomized patients with myasthenia gravis (MG).

Methods: This study is a post hoc analysis of data from a randomized trial of thymectomy in MG (Thymectomy Trial in Non-Thymomatous Myasthenia Gravis Patients Receiving Prednisone Therapy [MGTX]). MGTX was a multicenter, randomized, rater-blinded 3-year trial that was followed by a voluntary 2-year extension for patients with acetylcholine receptor (AChR) antibody-positive MG without thymoma.

Introduction: While there have been several articles detailing the importance of stakeholder engagement in research broadly and in practice-based research networks (PBRNs) specifically, few of these articles offer a replicable engagement approach that is detailed enough to translate to another setting. The goal of this article is to offer a detailed example of building stakeholder engagement infrastructure that could be replicated or translated to other settings.

Approach: We offer a review of 1 regional PBRN's approach to building a stakeholder engagement infrastructure over a 2-year period by describing engagement activities deployed across a large, regional PBRN including a needs assessment around research and training conducted in each state of the network and a centralized conference where themes from that needs assessment were leveraged to produce a stakeholder-defined research agenda and elect a steering committee.

Phenotypic Refinement of Heart Failure in a National Biobank Facilitates Genetic Discovery.

Cardiology Division and Cardiovascular Research Center (K.G.A., G.M., L.-C.W., M.E.L., C.N.-C., P.T.E., S.K., S.A.L.), Massachusetts General Hospital, Boston.

Background: Heart failure (HF) is a morbid and heritable disorder for which the biological mechanisms are incompletely understood. We therefore examined genetic associations with HF in a large national biobank, and assessed whether refined phenotypic classification would facilitate genetic discovery.

Methods: We defined all-cause HF among 488 010 participants from the UK Biobank and performed a genome-wide association analysis.

Background: Electrical conduction from the cardiac sinoatrial node to the ventricles is critical for normal heart function. Genome-wide association studies have identified more than a dozen common genetic loci that are associated with PR interval. However, it is unclear whether rare and low-frequency variants also contribute to PR interval heritability.

Objective: To evaluate the benefit of statistical SPECT processing over traditional subtraction methods, we compared ictal-interictal SPECT analyzed by statistical parametric mapping (SPM) (ISAS), statistical ictal SPECT coregistered to MRI (STATISCOM), and subtraction ictal-interictal SPECT coregistered with MRI (SISCOM) in patients with MRI-negative focal temporal lobe epilepsy (nTLE) and extratemporal lobe epilepsy (nETLE).

Methods: We retrospectively identified 49 consecutive cases of drug-resistant focal epilepsy that had a negative preoperative MRI and underwent interictal and ictal SPECT prior to resective epilepsy surgery. Interictal and ictal SPECT scans were analyzed using SISCOM, ISAS, and STATISCOM to create hyperperfusion and hypoperfusion maps for each patient.
