Aims: To evaluate the impact of different right and left ventricular lead positions (RV-LP and LV-LP) on the risk of therapy for ventricular tachycardia/ventricular fibrillation in patients with a cardiac resynchronization therapy device (CRT-D). Methods and results: We performed a large nationwide cohort study on patients in Denmark receiving a CRT-D device from 2008 to 2012 from the Danish Pacemaker and implantable cardioverter defibrillator (ICD) registry. Lead positions were registered during the implantation and categorized as anterior/lateral/posterior and basal/mid-ventricular/apical for the LV-LP, and as apical/non-apical for the RV-LP...

Motor neuron disease (MND) is a neurodegenerative disease and manifested as progressive decline in physical, respiratory, swallowing and communication function, and ultimately death. Traditional model of care was fragmented and did not match with multifacet needs of patients and carers. Furthermore, there could be lack of integrated care at end of life for patients with MND in most lower- and middle-income countries or in places with inadequate palliative care (PC) coverage. In view of this, a special workgroup for patients with MND, which includes neurologist, respiratory physician, rehabilitation specialist, and PC physician was formed in Hong Kong since year 2011...

BACKGROUND: Migraine-related nausea is associated with significant disability, increased burden of disease, and personal distress. Nausea can lead to delays or avoidance of initiating oral migraine treatment, sometimes resulting in treatment failures and poor outcomes. Nausea is often a symptom of migraine, but nausea may also be a consequence of treatment (ie, treatment emergent nausea [TEN]). Relieving nausea and minimizing TEN are important goals in acute migraine therapy. METHODS: We analyzed data from the COMPASS study, a randomized, double blind, double-dummy, comparative efficacy study that contrasted two active treatments, AVP-825 (breath-powered intranasal delivery of powdered sumatriptan 22 mg) and oral sumatriptan tablets (100 mg)...

Cardiac fibrosis is a common pathological process in cardiac disease and may lead to heart failure. It can also cause sudden death even in those without cardiac symptoms. Tissue fibrosis can be categorized into two categories: replacement fibrosis (also called reparative fibrosis) and reactive fibrosis. In replacement fibrosis, infiltration of inflammatory cells and accumulation of Extracellular Matrix (ECM) proteins are the initial steps in forming scarlike fibrotic tissue after acute cardiac injury and cardiac cell necrosis...

Neutrophils are involved in numerous immunological events. One mechanism of neutrophils to combat pathogens is the formation of neutrophil extracellular traps (NETs). Thereby, neutrophils use DNA fibers to form a meshwork of DNA and histones as well as several antimicrobial components to trap and kill invaders. However, the formation of NETs can lead to pathological conditions triggering among other things (e.g., sepsis or acute lung failure), which is mainly a consequence of the cytotoxic characteristics of accumulated extracellular histones...

Observing someone else perform an action can lead to false memories of self-performance - the observation inflation effect. One explanation is that action simulation via mirror neuron activation during action observation is responsible for observation inflation by enriching memories of observed actions with motor representations. In three experiments we investigated this account of source memory failures, using a novel paradigm that minimized influences of verbalization and prior object knowledge. Participants worked in pairs to take turns acting out geometric shapes and letters...

BACKGROUND: Heart failure (HF) is a major cause of cardiovascular admissions and hypertensive heart failure (HHF) is the most common cause of HF admissions in sub-Saharan Africa, Nigeria inclusive. Right ventricular (RV) dysfunction is being increasingly recognized in HF and found to be an independent predictor of adverse outcomes in HF. This study aimed to determine the prevalence of RV systolic dysfunction in HHF by several echocardiographic parameters. METHODOLOGY: One hundred subjects with HHF were recruited consecutively into the study along with 50 age and sex-matched controls...

OBJECTIVE: Fibrodysplasia ossificans progressiva (FOP) is an ultra-rare genetic disorder in which heterotopic bone forms in the soft tissues. This often occurs in response to injury or inflammation, leading to joint immobilization and significant disability. There are currently no definitive treatment options for this devastating disease. Although the most dramatic phenotype in FOP is the episodic and progressive heterotopic ossification, patients report a number of symptoms that affect other organ systems...

Globally, there is an alarming decline in sperm count. Very often hormonal supplementation fails to restore normal sperm count. Sertoli cells (Sc) present within seminiferous tubules provide appropriate niche and factors required for the differentiation of germ cells (Gc) into mature sperm (spermatogenesis). Functionally compromised Sc may be one of the reasons for failure of hormones to facilitate normal spermatogenesis. Although role of secretory proteins and signaling molecules of Sc has been studied well, role of transcription factors regulating sperm count has not been addressed appropriately...

INTRODUCTION: Cardiac resynchronization therapy (CRT) using biventricular pacing (BVP) is effective in patients with heart failure, bundle branch block (BBB) or right ventricular pacing. Permanent His bundle pacing (HBP) has been reported as an alternative option for CRT. OBJECTIVE: The aim of the study was to assess the feasibility and outcomes of HBP in CRT eligible or failed patients. METHODS: HBP was attempted as a rescue strategy in patients with failed LV lead or non-response to BVP (Group I); or as a primary strategy in patients with AV block, BBB, or high ventricular pacing burden as an alternative to BVP (Group II) in patients with indications for CRT...

Extracellular fluid volume expansion is nearly universal in patients with CKD. Such volume expansion has features similar to the syndrome of heart failure with preserved ejection fraction, which not only leads to symptoms but can also lead to further organ damage. Unique treatment challenges are present in this patient population, including low glomerular filtration, which limits sodium chloride filtration, intrinsic tubule predisposition to sodium chloride retention, and proteinuria. In addition, pharmacokinetic considerations alter the disposition of diuretics in patients with CKD and nephrotic syndrome...

Cardiomyocyte death is an important pathogenic feature of ischemia and heart failure. Through this study, we showed the synergistic role of HIF-1α and FoxO3a in cardiomyocyte apoptosis subjected to hypoxia plus elevated glucose levels. Using gene specific small interfering RNAs (siRNA), semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR), western blot, immunofluorescence, nuclear and cytosolic localization and TUNEL assay techniques, we determined that combined function of HIF-1α and FoxO3a under high glucose plus hypoxia condition lead to enhanced expression of BNIP3 inducing cardiomyocyte death...

As the primary microtubule-organizing center, centrosomes play a key role in establishing mitotic bipolar spindles that secure correct transmission of genomic content. For the fidelity of cell division, centrosome number must be strictly controlled by duplicating only once per cell cycle. Proper levels of centrosome proteins are shown to be critical for normal centrosome number and function. Overexpressing core centrosome factors leads to extra centrosomes, while depleting these factors results in centrosome duplication failure...

Background -Myocardial infarction (MI) is a leading cause of heart failure and death worldwide. Preservation of contractile function and protection against adverse changes in ventricular architecture (cardiac remodeling) are key factors to limiting progression of this condition to heart failure. Consequently, new therapeutic targets are urgently required to achieve this aim. Expression of the Runx1 transcription factor is increased in adult cardiomyocytes following MI; however, the functional role of Runx1 in the heart is unknown...

Management of high-risk pulmonary embolism (PE) requires an understanding of the pathophysiology of PE, options for rapid clot reduction, critical care interventions, and advanced cardiopulmonary support. PE can lead to rapid respiratory and hemodynamic collapse via a complex sequence of events leading to acute right ventricular failure. Importantly, reduction in pulmonary vascular resistance must be accomplished either by systemic thrombolytics, catheter directed thrombolytics, endovascular clot extraction, or surgical embolectomy...
