OBJECTIVES: To describe the early uptake of edoxaban; the fourth direct oral anticoagulant (DOAC) to enter the market. METHODS: Using the Danish nationwide health registries, we identified new users of edoxaban (n = 609) from June 6 (day of marketing) through June 2017. For comparison, we also identified new users of dabigatran (n = 2211), rivaroxaban (n = 19 227), and apixaban (n = 14 736). Users were described regarding indication of use, previous anticoagulant experience, comorbidity, and co-medication...

BACKGROUND: Atrial fibrillation is the commonest cardiac dysrhythmia. It is associated with significant morbidity and mortality. There are two approaches to the management of atrial fibrillation: controlling the ventricular rate or converting to sinus rhythm in the expectation that this would abolish its adverse effects. OBJECTIVES: To assess the effects of pharmacological cardioversion of atrial fibrillation in adults on the annual risk of stroke, peripheral embolism, and mortality...

BACKGROUND: Atrial fibrillation increases stroke risk and adversely affects cardiovascular haemodynamics. Electrical cardioversion may, by restoring sinus rhythm, improve cardiovascular haemodynamics, reduce the risk of stroke, and obviate the need for long-term anticoagulation. OBJECTIVES: To assess the effects of electrical cardioversion of atrial fibrillation or flutter on the risk of thromboembolic events, strokes and mortality (primary outcomes), the rate of cognitive decline, quality of life, the use of anticoagulants and the risk of re-hospitalisation (secondary outcomes) in adults (>18 years)...

Amyloid β-protein (Aβ) assembly is a seminal process in Alzheimer's disease. Elucidating the mechanistic features of this process is thought to be vital for the design and targeting of therapeutic agents. Com-putational studies of the most pathologic form of Aβ, the 42-residue Aβ42 peptide, have suggested that hydrogen bonding involving Ser 26 may be particularly important in organizing a monomer folding nucleus and in subse-quent peptide assembly. To study this question, we ex-perimentally determined structure-activity relationships among Aβ42 peptides in which Ser 26 was replaced with Gly, Ala, α-aminobutryic acid (Abu), or Cys...

It is known that the formation of ice crystals has a negative impact on the flesh quality of frozen meat. This study focuses on how the formation of ice crystals in the dorsal ordinary muscle affects the flesh quality of frozen horse mackerel (Trachurus japonicus). Freeze-thawed muscle specimens (F-TMS) of horse mackerel were first stored at -24°C and then thawed. The K-value, expressible water, breaking strength of unfrozen muscle specimens (UMS) and F-TMS, and histological structure (light microscope: LM, scanning electron microscope: SEM) of UMS, frozen muscle specimens (FMS) and F-TMS were investigated...

Ischaemic stroke is rare in premenopausal women but risk increases with advancing age and doubles in the ten years following the menopause. Up to the age of 75 years men have a 25% higher risk of suffering a stroke compared with women. However, the increased life expectancy of women ultimately results in a higher overall incidence. Twice as many women die from stroke compare with breast cancer. Women with cerebrovascular disease are more likely to present with atypical symptoms than men. Altered mental status (including unresponsiveness, confusion and behavioural change) is the most common nonconventional symptom, and is reported by 23% of women compared with 15% of men...

BACKGROUND: Steroid-eluting pacemaker leads suppress acute rises in pacing threshold by preventing inflammatory processes. However, we occasionally encounter not persistent but transient rise in the atrial capture threshold (TRACT) early after pacemaker implantation. We believe that this phenomenon is under-recognized in clinical practice and may potentially lead to unnecessary re-intervention. We aimed to clarify the prevalence, predictors, and possible mechanisms of TRACT. METHODS AND RESULTS: We reviewed clinical records from 239 consecutive patients who underwent dual-chamber pacemaker implantation for sick sinus syndrome (SSS) (N = 102) or atrioventricular block (AVB) (N = 137)...

Trabecular bone is composed of organized mineralized collagen fibrils, which results in heterogeneous and anisotropic mechanical properties at the tissue level. Recently, biomechanical models computing stresses and strains in trabecular bone have indicated a significant effect of tissue heterogeneity on predicted stresses and strains. However, the effect of the tissue-level mechanical anisotropy on the trabecular bone biomechanical response is unknown. Here, a computational method was established to automatically impose physiologically relevant orientation inherent in trabecular bone tissue on a trabecular bone microscale finite element model...

Atrial fibrillation is the most common arrhythmia worldwide, and carries a significantly increased risk of thromboembolic stroke. Initially, vitamin K antagonists were used as stroke prophylaxis; but more recently, a group of drugs known as novel oral anticoagulants have been developed. Apixaban belongs to this group of drugs, and is a factor Xa inhibitor that has emerged as a popular pharmacological agent worldwide. In this review, we will provide an overview of the pivotal trials in the development of apixaban, while also critically evaluating the new emerging real-world data, and discussing the effectiveness, safety, economic viability and future prospects of apixaban and how it impacts on patient outcomes in those with non-valvular atrial fibrillation...

BACKGROUND: Advancing age is a prominent risk factor for atrial fibrillation (AF). Shorter telomere length is a biomarker of biological aging, but the link between shorter telomere length and increased risk of AF remains unclear. We examined the association between shorter leukocyte telomere length (LTL) and incident AF. METHODS AND RESULTS: We included AF-free participants from the observational Framingham Heart Study Offspring cohort from 1995 to 1998, who had LTL measurements...

BACKGROUND: Rhythm control is challenging in patients with extended atrial fibrillation (AF) duration and persistent/long-standing persistent AF. Among surgical approaches to treat AF, the Cox maze procedure performed using alternative energy sources remains superior to other beating heart techniques. We examined permanence of safety and success for the on-pump, minimally invasive, stand-alone Cox maze procedure 5 years after surgery. METHODS AND RESULTS: Stand-alone, right 5 cm minithoracotomy, Cox maze III/IV procedure for nonparoxysmal AF was conducted in 133 patients (mean follow-up=65±34 months)...

Bone is a hierarchical material exhibiting different fracture mechanisms at each length scale. At the submicroscale, the bone is composed of mineralized collagen fibrils (MCF). At this scale, the fracture processes in cortical bone have not been extensively studied in the literature. In this study, the influence of MCF size and orientation on the fracture behavior of bone under both transverse and longitudinal loading was investigated using novel 3D models of MCF networks with explicit representation of extra-fibrillar matrix...

Src has been reported to mediate tissue fibrosis in several organs, but its role in peritoneal fibrosis remains unknown. In this study, we evaluated the therapeutic effect of KX2-391, a highly selective inhibitor of Src, on the development of peritoneal fibrosis in a rat model. Daily intraperitoneal injections of chlorhexidine gluconate induced peritoneal fibrosis, as indicated by thickening of the submesothelial area with an accumulation of collagen fibrils and activation of myofibroblasts. This was accompanied by time-dependent phosphorylation of Src at tyrosine 416...

BACKGROUND: The controversy over electrotherapy for patients aged >80 years occurs already at the stage of qualification for this treatment type and concerns optimal device selection, the implantation strategy, and the overall benefit from pacemaker therapy. The group also has a considerable number of cardiovascular risk factors, and the data from the literature on the impact of the pacing mode on the remote prognosis of this group are ambiguous. OBJECTIVE: Assessment of the risk factors for death among patients with implanted pacemakers >80 years of age in a 4-year follow-up...

PURPOSE OF REVIEW: Triggers for atrial fibrillation are found outside the pulmonary veins in 12-20% of cases. The role of addressing these triggers during catheter ablations has not been well defined. Therefore, the aim of this review is to summarize the effect of ablation of nonpulmonary vein triggers in addition to pulmonary vein isolation across the spectrum of atrial fibrillation in patients receiving catheter ablation. RECENT FINDINGS: In paroxysmal atrial fibrillation, an inducible nonpulmonary vein trigger is an independent predictor of recurrence...

Amyloidosis is a heterogeneous group of protein deposition diseases with more than 40 known clinical presentations. Localized amyloidosis occurs when the protein deposits exist in a singular location. Patients with diabetes mellitus who inject insulin at the same site can develop localized insulin-derived amyloidosis (AIns) at the injection site, which can be confused clinically with lipoma, lipohyperplasia, lipoatrophy, and fat necrosis. Histologic examination is performed to confirm localized AIns. We report a case of a patient with a long history of type 2 diabetes who presented with a subcutaneous mass in the abdomen at a preferred insulin injection site...
