Brendan Mclean, Rohit Shankar, Jane Hanna, Caryn Jory, Craig Newman
This review looks at the strategies that may help to reduce the risk of sudden unexpected death in epilepsy beyond that of trying to achieve seizure cessation, which is not possible for up to 30% of patients with epilepsy. These strategies include seizure safety checklists, mobile phone technology, telehealth and various devices currently available or in development. We highlight interventions where there is evidence of benefit, and draw attention for the need both to involve patients with epilepsy in risk reduction and to improve communication with those at risk...

BACKGROUND: Cardiac sarcoidosis (CS) may manifest as arrhythmia or even sudden cardiac death. Because patients with CS often present with nonspecific symptoms, normal electrocardiography, and preserved left ventricular ejection fraction, a reliable diagnostic tool for the work-up of CS is needed. Late gadolinium enhancement-cardiovascular magnetic resonance has proven diagnostic value in CS but has some limitations that may be overcome by adding newer cardiovascular magnetic resonance mapping techniques...

REVIEW
Davide Leoni, Jordi Rello
The incidence of sepsis is increasing, and the condition is now the leading cause of death in general intensive care units (ICUs). Our review failed to identify studies of the causes of cardiac arrest among infected patients, even though non-cardiac causes represent 15% of out-of-hospital cardiac arrests and though one-third of events have positive blood cultures. Sudden cardiac arrest is the result of local damage to the heart and of the impact of systemic and pulmonary conditions on cardiac performance, and its danger is underestimated...

Objective: To analyze long-term mortality and patients characteristics of cardiac resynchronization therapy (CRT) for patients with chronic heart failure. Methods: In-patients with chronic heart failure who received CRT in the three medical centers(Bethune International Peace Hospital, General Hospital of Shenyang Military Command of Chinese People's Liberation Army, and 251 Hospital of People's Liberation Army)from March 2001 to June 2013 were included.Mortality and related causes, echocardiographic parameters were analyzed...

Patients with kidney disease have a significantly increased cardiovascular morbidity and mortality. Especially diabetics have an increased risk to develop renal insufficiency and cardiovascular events. Two recent studies show that the SGLT2 inhibitor Empagliflozin and the GLP1 agonist Liraglutid are able to lower the cardiovascular risk of type2 diabetics with renal insufficiency. Recent observations suggest that bradycardia and asystole are main triggers for sudden cardiac death in patients with chronic kidney disease...

Domperidone has been used as a galactagogue; however, solid evidence from an adequate sized randomized clinical trial is missing. Optimal dosage, start of treatment, length of treatment and scope of patients who can benefit also remain unknown. Although milk obtained after domperidone administration has not been shown to have untoward effects on newborns, no sufficiently large randomized clinical trial has been done to establish safety. Domperidone has repeatedly been shown to produce sudden cardiac death, starting at 30 mg/day...

Developments in post-mortem imaging increasingly focus on addressing recognised diagnostic weaknesses, especially with regard to suspected natural deaths. Post-mortem MR angiography (PMMRA) may offer additional diagnostic information to help address such weaknesses, specifically in the context of sudden cardiac death. Complete filling of the coronary arteries and acceptable contrast with surrounding tissue are essential for a successful approach to PMMRA. In this work, the suitability of different liquids for inclusion in a targeted PMMRA protocol was evaluated...

REVIEW
Charlotte Glinge, Stefan Sattler, Reza Jabbari, Jacob Tfelt-Hansen
Sudden cardiac death (SCD) from ventricular fibrillation (VF) during coronary artery disease (CAD) is a leading cause of total and cardiovascular mortality, and in more than half of SCD cases VF occurs as the first symptom of CAD. Several epidemiological studies have shown that sudden death of a family member is a risk factor for SCD and VF during acute myocardial infarction (MI), independent of traditional risk factors including family history of MI, suggesting a genetic component in the susceptibility to VF...

Among heart irregularities, congenital pericardial defect is an unusual anomaly, and is typically left dominant. However, cases of right pericardial defect with heart herniation are extremely rare. This is a case of congenital right pericardial defect with herniation of the right ventricle free wall and right ventricular outflow tract. The patient is asymptomatic and refused further intervention but even indolent discomfort underscores the risks of iatrogenic injuries to the heart and sudden death caused by mechanical pathogenesis due to changes in anatomical positions of the cardiac structures...

Bacterial myocarditis is an uncommon condition and only a few fatal cases in adults are reported in the scientific literature. Death from acute bacterial myocarditis in children is extremely rare. We report an unusual case of fatal bacterial myocarditis in a seven-year-old girl, who had a history of cough for a month and fever for two days. She was given symptomatic treatment by a local physician without suspecting her clinical condition. Her condition rapidly deteriorated and she was brought in dead to the hospital...

BACKGROUND: -Ventricular arrhythmia is a leading cause of cardiac mortality. Most antiarrhythmics present paradoxical pro-arrhythmic side effects, culminating in a greater risk of sudden death. METHODS: -We describe a new regulatory mechanism linking mitogen-activated kinase kinase-7 (MKK7) deficiency with increased arrhythmia vulnerability in hypertrophied and failing hearts using mouse models harbouring MKK7 knockout or overexpression. The human relevance of this arrhythmogenic mechanism is evaluated in human induced pluripotent stem cells-derived cardiomyocytes (iPSC-CMs)...

Dying and death in modern societies are subject to profound social, professional and cultural-religious changes. Secularization and a stronger differentiation of societies have led to a change in the way humans handle the dying process. Normatively ritualized collective behaviour has been replaced by an individual, subjectivized approach. In late modern societies there are many different views of what "successful" or "good" dying means.In the article this change is described by the following seven theses: 1...

BACKGROUND: Cryopreservation of epididymal spermatozoa is important in cases in which it is not possible to collect semen using normal methods, as the sudden death of an animal or a catastrophic injury. However, the freezing and thawing processes cause stress to spermatozoa, including cold shock, osmotic damage, and ice crystal formation, thereby reducing sperm quality. We assessed the motility (%), motion kinematics, capacitation status, and viability of spermatozoa using computer-assisted sperm analysis and Hoechst 33258/chlortetracycline fluorescence staining...

BACKGROUND: Population-based studies suggest that genetic factors contribute to sudden cardiac death (SCD). METHODS AND RESULTS: In the first part of the present study (Diagnostic Data Influence on Disease Management and Relation of Genetic Polymorphisms to Ventricular Tachy-arrhythmia in ICD Patients [DISCOVERY] trial) Cox regression was done to determine if 7 single-nucleotide polymorphisms (SNPs) in 3 genes coding G-protein subunits (GNB3, GNAQ, GNAS) were associated with ventricular tachyarrhythmia (VT) in 1145 patients receiving an implantable cardioverter-defibrillator (ICD)...

: Myocardial infarction is one of the leading causes of cardiac dysfunction, failure and sudden death. Post infarction cardiac remodeling presents a poor prognosis, with 30%-45% of patients developing heart failure, in a period of 5-25years. Oxidative stress has been labelled as the primary causative factor for cardiac damage during infarction, however, the impact it may have during the process of post infarction remodeling has not been well probed. In this study, we have implemented iTRAQ proteomics to catalogue proteins and functional processes, participating both temporally (early and late phases) and spatially (infarct and remote zones), during post myocardial infarction remodeling of the heart as functions of the differential oxidative stress manifest during the remodeling process...

OBJECTIVE: Marfan syndrome (MFS) leads to aortic root aneurysm, while descending thoracic aortic aneurysm (TAA) occurs less commonly. Abdominal aortic aneurysm (AAA) is rarely reported in MFS. Risk factors for AAA are poorly understood and there are no guidelines for AAA screening in MFS. We sought to characterize AAA among Marfan patients in our center. METHODS: The records of 12 adults with MFS and AAA disease were reviewed. Clinical features, imaging, operative reports, and outcomes were analyzed...

A 6-month-old female pet rabbit was presented for routine ovariectomy. The pre-anaesthetic evaluation was unremarkable and no anaesthetic complications occurred during the procedure. However, at the end of the surgery, the rabbit suddenly showed acute bradycardia and cardiac death. Necropsy examination revealed marked dilation of the right ventricle, associated with diffuse thinning of the right ventricular free wall. Gross and histopathological findings were suggestive of a congenital dilated cardiomyopathy characterized by fibro-fatty replacement of the right ventricular myocardium...

There are two allelic forms of A1 and A2 of β-casein gene in dairy cattle. Proteolytic digestion of bovine β-casein A1 type produces bioactive peptide of β-casomorphin-7 known as milk devil. β-casomorphin-7 causes many diseases, including type 1 diabetes, cardiovascular disease syndrome, sudden death and madness. The aim of the present study was to determine the different allelic forms of β-casein gene in Iranian Holstein, Simmental and native cattle in order to identify A1 and A2 variants. The blood samples were collected randomly and DNA was extracted using modified salting out method...

BACKGROUND: The Encephalomyocarditis virus (EMCV) is a small, non enveloped, positive sense single-stranded RNA virus in the genus Cardiovirus, family Picornaviridae, with two known serotypes. It is spread worldwide and infects a huge range of vertebrate hosts with zoonotic potential for humans. The pig is the mammal most likely to be impacted on with the disease, but EMCV occurrence has also been reported in non-human primates and in a variety of domestic, captive and wild animals. Until now, human cases have been very rare and the risk appears to be almost negligible in spite of human susceptibility to the infection...

BACKGROUNDS: Patients with rheumatoid arthritis (RA) have increased risk of sudden cardiac death (SCD), which is two-fold higher than general population. The driving cause of SCD was considered due to lift-threatening arrhythmia where systemic inflammation acts as the pathophysiological basis linking RA to autonomicdysfunction. METHODS: To assess the sympathetic over-activity of "inflammatory reflex", we measured heart rate variability (HRV) in a rat collagen-induced arthritis (CIA) model, whose arthritis is induced in Lewis rats by intradermal injection of emulsion of type II collagen...
