Normal interventricular differences in tissue architecture underlie right ventricular susceptibility to conduction abnormalities in a mouse model of Brugada syndrome

ConclusionsNormal structural heterogeneities present in the RV are responsible for increased vulnerability to conduction slowing in the presence of reduced sodium channel function. Heterogeneous conduction slowing seen in the RV will predispose to functional block and the initiation of re-entrant ventricular arrhythmias.

ConclusionsFetuses with structurally normal hearts and sustained SVT can be effectively managed with transplacental drug therapy with minimal risk of intrauterine fetal demise. Treatment requires multiple anti ‐arrhythmic agents in over half of cases. Later gestational age at fetal diagnosis and the presence of depressed fetal ventricular function, but not hydrops, predict postnatal arrhythmia burden.This article is protected by copyright.

Authors: Hakim SM, Elfawy DM, Elserwi HB, Saad MK Abstract INTRODUCTION: The aim of this review is to examine current evidence on value of new ST-segment or T-wave changes for prediction of major adverse cardiac events (MACE) after vascular surgery. EVIDENCE ACQUISITION: We searched PudMed, EMBASE and Cochrane Library databases for studies examining the relation between new ST-segment elevation or depression or T-wave inversion and MACE following vascular surgery. MACE was defined as fatal or non-fatal myocardial infarction, cardiac death, unstable angina, cardiac arrest, congestive heart failure, ischemic pulm...

AbstractBackgroundImplantable cardioverter-defibrillators (ICDs) are designed to deliver therapy in the event of malignant ventricular arrhythmias. Despite their benefits, some ICD recipients regret their decision on device implantation.ObjectivesThe aim of this study was to evaluate the incidence, predictors, and consequences of recipients that regretted their decision after implantation.MethodsA questionnaire-based cross-sectional survey of consecutive ICD recipients examined during a  routine outpatient follow-up visit was conducted. Their level of depression and anxiety was assessed with the hospital anxiety and d...

DiscussionIn hindsight I feel there are very few alternative causes for an ECG like this other than an acute LAD occlusion. I believe this is one of those'subtle STEMI'cases where neither the ECG nor the symptoms are very obvious or severe and the usual evolution is not seen.I think of these cases as'insidious infarcts'and I have seen this in all infarct territories and I do not think they are particularly rare. Essentially the patient is fairly comfortable and the ECG is not obvious but the patient ended up with Q waves, huge troponins and we missed the opportunity to reperfuse the artery when it counts. These patients te...

Conclusions In this trial, there does not appear to be a significant difference in electrocardiographic changes in patients with Brugada syndrome when propofolversus etomidate were administered for induction of anesthesia. This study did not investigate electrocardiographic changes related to propofol used as an infusion for maintenance of anesthesia, so future studies would be warranted before conclusions about safety of propofol infusions in patients with Brugada syndrome can be determined.Editor ’s PerspectiveWhat We Already Know about This TopicBrugada syndrome is an inherited cardiac ion channel disorder that pl...

Abstract The current psychopharmacological treatment approaches for major depression focus on monoaminergic interventions, which are ineffective in a large proportion of patients. Globally, treatment-resistant bipolar depression (TRBD) affects up to 33% of depressive patients receiving treatment. Certain needs are still unmet and require new approaches. Many studies are in favor of treatments with ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist, even in single use, whose effects emerge in minutes to hours post administration. However, little data are available on ketamine performance in TRBD patients ...

Conclusions: In a large population of patients with cardiac disease a significant educational gradient was found in mental and physical health and quality of life at hospital discharge. There was, however, no association between educational level and risk of cardiac events or mortality 1 year after hospital discharge. PMID: 32009558 [PubMed - as supplied by publisher]

Postoperative pain is not adequately managed in greater than 40% of surgical patients and is a high priority for perioperative research. In this meta-analysis, we examined studies comparing postoperative opioid consumption and pain scores in surgical patients who received methadone by any route vs those who received another opioid by any route. Studies were identified from PubMed, Cochrane, Web of Science, EMBASE, and Scopus from January 1966 to November 2018. Pooled odds ratios were calculated for a primary outcome of postoperative opioid consumption and secondary outcomes of time-to-extubation, time-to-first postoperativ...

Authors: Patel P, Konala VM, Adapa S, Gayam V, Sahasranam P, Bose S, Golez CD, Naramala S Abstract Cyanide is notoriously known to the public for more than a century now as a weapon of mass destruction (Zyklon B gas - hydrogen cyanide used by Nazis), an agent for chemical warfare during World War I (hydrogen cyanide) and very infamous "Suicide Pill" used in the past by military and espionage organizations during World War II (potassium cyanide). During the modern industrial era, cyanide poisoning is commonly associated with the industrial exposure and domestic fires. But there is little awareness about po...

However, behind its familiar face, Marfan syndrome hides less well-known features.Areas covered: The German Marfan Organization listed unusual symptoms and clinical experts reviewed the literature on clinical features of Marfan syndrome not listed in the Ghent nosol...
