Kunal Pradip Verma, David Adam
A 62 year old male presented to his treating cardiologist for routine interrogation of his implantable cardiac defibrillator (ICD) on the background of severe ischaemic cardiomyopathy and end-stage kidney disease on haemodialysis. The device log revealed multiple paroxysms of atrial fibrillation (AF); however, upon scrutinising these episodes it was evident that they always corresponded to episodes of haemodialysis whilst dialysing through a chronic dialysis catheter, but not whilst dialysing via an arteriovenous fistula...

Death in patients with postinfarction aneurysms of the left ventricle (LV) is mainly caused by life-threatening ventricular arrhythmias - ventricular tachycardias (VTs) and ventricular fibrillations (VFs). Surgical reconstruction of the LV may potentially lead to disruption of the re-entry mechanism, lying at the basis of ventricular tachyarrhythmias. A series of authors demonstrated high efficacy of such procedures as endocardectomy and radiofrequency ablation of the borderline zone of the LV. But high incidence of relapses, difficulty detecting the localization of VT and performing radiofrequency ablation (RFA), as well as high incidence of spontaneous and induced VTs in patients with postinfarction aneurysms of the LV have preserved dissatisfaction with the currently existing techniques...

Psoriasis is a chronic cutaneous disease known to be related with systemic disease; however, the association between psoriasis and diabetic complications has not been previously reported. Diabetic microvascular complications include diabetic retinopathy (DR), nephropathy, and neuropathy, and overt diabetic nephropathy can lead to the end-stage renal disease (ESRD).The present study investigated the association between psoriasis and non-proliferative DR (NPDR) or proliferative DR (PDR) or ESRD. We analyzed the relationship between diabetic complication and psoriasis using data from the National Health Insurance Service between 2009 and 2015...

BACKGROUND/AIMS: Single or multiple applications of irritants can lead to occupational contact dermatitis, and most commonly irritant contact dermatitis (ICD). Tandem irritation, the sequential application of two irritants to a target skin area, has been studied using the Tandem Repeated Irritation Test (TRIT) to provide a more accurate representation of skin irritation. OBJECTIVE: Here we present an update to Kartono's review on tandem irritation studies since 2006 [1]...

BACKGROUND: Guidelines for anticoagulation in atrial fibrillation (AF) assume that stroke risk scheme point scores correspond to fixed stroke rates. However, reported stroke rates vary widely across AF cohort studies, including studies from the same country. Reasons for this variation are unclear. This study compares methodologies used to assemble and analyze large AF cohorts worldwide and assesses potential bias in estimating stroke rates. METHODS AND RESULTS: From a previous systematic review of AF cohorts, we analyzed studies including at least 5000 patients...

A 41-year-old woman was visiting Oxford, where she had a sudden cardiac arrest. Cardiopulmonary resuscitation was started by a bystander until the paramedics arrived, who found her in ventricular fibrillation, and delivered three shocks. After 28 min she had return of spontaneous circulation. Emergency coronary angiography revealed normal coronary arteries. Echocardiography followed by a cardiac MRI showed non-dilated left ventricles with no evidence of late gadolinium enhancement. She had a single-chamber implantable-cardioverter defibrillator (ICD)...

BACKGROUND: In Poland, as in most other European countries, diseases of the respiratory system are the 4th leading cause of mortality; they are responsible for about 8% of all deaths in the European Union (EU) annually. To assess the socio-economic aspects of mortality, it has become increasingly common to apply potential measures rather than conventionally used ratios. OBJECTIVES: The aim of this study was to analyze years of life lost due to premature deaths caused by diseases of the respiratory system in Poland from 1999 to 2013...

Immunogenic cell death (ICD) is a type of cell death that is accompanied by the release of damage-associated molecular patterns (DAMPs) and results in a dead-cell antigen-specific immune response. Here, we report that spautin-1, an inhibitor of ubiquitin-specific peptidases, triggers immunogenic cancer cell death in vitro and in vivo . The anticancer activity of spautin-1 occurs independent of autophagy inhibition, but depends on the intrinsic mitochondrial apoptosis pathway. Spautin-1 causes mitochondrial oxidative injury, which results in JUN transcription factor activation in a JNK-dependent manner...

BACKGROUND: In patients with Chagas cardiomyopathy (ChCM), sudden cardiac death (SCD) is the leading cause of mortality. Implantable cardioverter-defibrillator (ICD) is a well-established therapy for secondary prevention in patients with structural heart disease, but there are conflicting opinions regarding its efficacy and safety in patients with ChCM. The aim of this meta-analysis was to assess the efficacy of the ICD for secondary prevention in patients with ChCM, comparing mortality as the primary outcome of patients treated with ICD with those treated with amiodarone...

An infantile spasm is a brief seizure type that is characteristic of West syndrome. Many infants present with infantile spasms between 3-12 months of age. Early diagnosis and proper treatment of patients with infantile spasms can lead to improved clinical outcomes. However, proper identification of these patients using claims data with validation has not been performed. The authors developed and tested several algorithms using claims data. Claims data consisted of using International Classification of Disease (ICD), Current Procedural Terminology (CPT), and prescription codes...

Background: System of Health Accounts 2011 (SHA 2011) is a new health care accounts system, revised from SHA 1.0 by the Organisation for Economic Co-operation and Development (OECD), the World Health Organization (WHO) and Eurostat. It keeps the former tri-axial relationship and develops three analytical interfaces, in order to fix the existing shortcomings and make it more convenient for analysis and comparison across countries. SHA 2011 was introduced in China in 2014, and little about its application in China has been reported...

INTRODUCTION: Recognition of implantable cardioverter defibrillator (ICD) lead malfunction before occurrence of life threatening complications is crucial. We aimed to assess the effectiveness of remote monitoring associated or not with a lead noise alert for early detection of ICD lead failure. METHODS: From October 2013 to April 2017, a median of 1224 [578-1958] ICD patients were remotely monitored with comprehensive analysis of all transmitted materials. ICD lead failure and subsequent device interventions were prospectively collected in patients with (RMLN) and without (RM) a lead noise alert (Abbott SecureSense™ or Medtronic Lead Integrity alert™) in their remote monitoring system...
