Aims: The primary objective of this study was to use computer simulations to suggest an optimal age for initiation of screening for unknown atrial fibrillation and to evaluate if repeated screening will add value. Methods and results: In the absence of relevant clinical studies, this analysis was based on a simulation model. More than two billion different designs of screening programs for unknown atrial fibrillation were simulated and analysed. Data from the published scientific literature and registries were used to construct the model and estimate lifelong effects and costs...

Aims: Patients with atrial fibrillation (AF) under the age of 65 and CHA2DS2-VASc risk score of 0 in men or 1 in women are considered to be at low risk for ischaemic stroke, and therefore without benefit of oral anticoagulation therapy. The objective of this study is to assess the incidence and predictors of ischaemic stroke among low-risk patients with AF identified from a National Patient Register. Methods and results: A retrospective study of 25 252 low-risk AF patients (age 18-64) out of total 345 123 AF patients identified from the Swedish Nationwide Patient Register for the period 1 January 2006 to 31 December 2012...

RATIONALE: Alzheimer's disease (AD) is a neurodegenerative disorder with irreversible loss of intellectual abilities. Current therapies for AD are still insufficient. OBJECTIVE: In this study, the effect of ellagic acid on learning and memory deficits was evaluated in intrahippocampal amyloid beta (Aβ25-35)-microinjected rats and its modes of action were also explored. METHODS: AD rat model was induced by bilateral intrahippocampal microinjection of Aβ25-35 and ellagic acid was daily administered (10, 50, and 100 mg/kg), and learning, recognition memory, and spatial memory were evaluated in addition to histochemical assessment, oxidative stress, cholinesterases activity, and level of nuclear factor-kappaB (NF-κB), Toll-like receptor 4 (TLR4), and nuclear factor (erythroid-derived 2)-like 2 (Nrf2)...

A thin fluid layer in alveoli is normal and results from a balance of fluid entry and fluid uptake by transepithelial salt and water reabsorption. Conventional wisdom suggests the reabsorption is via epithelial Na(+) channels (ENaC), but if all Na(+) reabsorption was via ENaC, then amiloride, an ENaC inhibitor, should block AFC. But amiloride blocks only half of AFC. The reason for failure to block is clear from single channel measurements from alveolar epithelial cells: ENaC channels are observed, but another channel is present at the same frequency that is non-selective for Na(+) over K(+), has a larger conductance, and shorter open and closed times...

Indeterminate small (<2 cm) nodules are often discovered in cirrhotics who undergo contrast enhanced imaging for further characterization of lesions detected on ultrasound surveillance for hepatocellular carcinoma (HCC). These are either arterially enhancing (without venous washout or capsule) or are non-enhancing (with washout). Differentials include small HCCs (14-23%), atypical arterio-portal shunts, regenerative, and dysplastic nodules. A risk score that combines imaging features (arterial enhancement and nodule size) with clinical (age, prior h/o HCC) and laboratory features (albumin, AFP, hepatitis B 'e' antigen) appear to be superior to radiological features alone in the risk stratification of these nodules...

A 37-year-old male living in Oman was seen by his physician with complaints of cough, body aches with bilateral lower limb weakness and on and off fever. He was diagnosed with HIV infection and culture from blood and bone marrow grew Talaromyces marneffei. He had travelled to Malaysia on several occasions. Treatment with liposomal amphotericin B resulted in complete cure. This case is reported for its rarity and unusual presentation to alert clinicians and microbiologists to consider T. marneffei as an etiology in high risk individuals...

Paclitaxel-coated drug-coated balloons have significantly improved short-term and mid-term clinical outcomes in patients with symptomatic femoropopliteal peripheral artery disease. However, long-term results are awaited. Furthermore, the clinical success of drug-coated balloons in the infrapopliteal peripheral arteries has been more modest and overall similar to traditional balloon angioplasty, and remains an area of unmet clinical need. This article provides an overview of the clinical evidence for paclitaxel-coated balloons in the femoropopliteal and infrapopliteal peripheral artery distributions and future directions in this area...

Dikkoppf-1 (DKK1) is an antagonist of the canonical Wnt signaling pathway. The importance of DKK1 as a diagnostic and therapeutic agent in a wide range of diseases along with its significance in a variety of biological processes accentuate the necessity to decipher its 3D structure that would pave the way towards the development of relevant selective inhibitors. A DKK1 structure model predicted by the Robetta server with structural refinements including a 10 ns molecular dynamics run was subjected to functional and docking analyses...

Compact bone (cortical or dense bone) is among the organs that contain multipotent mesenchymal stromal cells (MSCs). Unlike bone marrow plugs where MSCs were initially isolated, compact bone has minimal (amount of) hematopoietic cells and thus facilitates the MSCs isolation process. In vitro, MSCs from compact bone show multipotency and differentiation into mesenchymal tissues such as bone, adipose, and cartilage, under certain conditions. MSCs therapy has been promising in preclinical and clinical studies against autoimmune diseases...

A new opecoelid trematode is reported from fishes of the Lethrinidae, Lutjanidae and Nemipteridae off Lizard Island on the northern Great Barrier Reef, Australia. The new species keys to Neolebouria Gibson, 1976 and shows strong similarity to several species of that genus, but is not consistent with the type-species, N. georgiensis Gibson, 1976, or others known from temperate/polar and/or deep-sea fishes. The new species is also phylogenetically distant from N. lanceolata (Price, 1934) Reimer, 1987, the only representative of the genus for which molecular data are available...
