BACKGROUND: Cardiovascular diseases are one of the leading causes of death in the industrialized world. Sudden cardiac death is very often the first manifestation of the disease and it occurs in the prehospital setting. The determination of the sudden cardiac death phenotype is challenging. It requires prospective studies in the community including multiple sources of case ascertainment that help to identify the cause and circumstances of death. The aim of the Clinical and Pathological Registry of Tarragona (ReCaPTa) is to study incidence and etiology of Sudden Cardiac Death in the Tarragona region (Catalonia, Spain)...

Iran, especially its western provinces, is one of the most chickpea producing countries of the world with the yield about 500 kg/ ha in average. Narrow genetic variability for chickpea is one of the most limitations in conventional breeding approaches. In this study, derived genetic variation among 94 chickpea (Bivanij cultivar) mutant lines produced by Ethyl Methane Sulfonate (EMS) were assessed based on ISSR, RAPD markers in M4 and morpho-agronomic traits in M3 generation. The induced variation via EMS in field experiment, showed significant differences among mutant lines based on almost measured traits...

For more than half a century, genotoxic agents have been used to induce mutations in the genome of model organisms to establish genotype-phenotype relationships. While inaccurate replication across damaged bases can explain the formation of single nucleotide variants, it remained unknown how DNA damage induces more severe genomic alterations. Here, we demonstrate for two of the most widely used mutagens, i.e. ethyl methanesulfonate (EMS) and photo-activated trimethylpsoralen (UV/TMP), that deletion mutagenesis is the result of polymerase Theta (POLQ)-mediated end joining (TMEJ) of double strand breaks (DSBs)...

BACKGROUND AND OBJECTIVE: The transfer of acute ischemic stroke (AIS) patients to a comprehensive stroke center (CSC) must be rapid. Delays pose an obstacle to time-sensitive stroke treatments and, therefore, increase the likelihood of exclusion from endovascular stroke therapy. This study aims to evaluate the impact of the Stroke Rescue Program, with its goal of minimizing interfacility transfer delays and increasing the number of transport times completed within 60 minutes. METHODS: The Stroke Rescue Program was initiated to facilitate the rapid transfer of AIS patients from regional primary stroke centers (PSCs) to the network's CSC...

OBJECTIVES: The ultrasonic NO PAIN technology (Electro Medical Systems, Nyon, CH) promises minimal pain during debridement due to linear oscillating action combined with a sinusoidal power output and feedback control. The aim of the present study was to measure pain perception on a visual analogue scale (VAS) during supportive periodontal therapy including debridement of hypersensitive teeth. Two ultrasonic scalers were used, one with and one without NO PAIN technology. MATERIAL AND METHODS: In a randomized-controlled clinical study with split-mouth design, 100 hypersensitive teeth matched for air blast hypersensitivity were either treated with the ultrasonic device Piezon Master 700 or the Mini Piezon (both EMS, Nyon, CH)...

Exosomes, the smallest subgroup of extracellular vesicles, have been recognized as extracellular organelles that contain genetic and proteomic information for long distance intercellular communication. Exosome-based drug delivery is currently a subject of intensive research. Here, we report a novel strategy to produce nanoscale exosome-mimics (EMs) in sufficient quantity for gene delivery in cancer both in vitro and in vivo. Size-controllable EMs were generated at a high yield by serial extrusion of non-tumorigenic epithelial MCF-10A cells through filters with different pore sizes...

Acute ischemic stroke is a challenging and time-sensitive diagnosis. Diagnosis begins with rapid detection of acute stroke symptoms by the patient, their family or caregivers, or bystanders. If acute stroke is suspected, EMS providers should be called for rapid assessment. EMS providers will utilize prehospital stroke tools to diagnose and determine potential stroke severity. Once at the hospital, the stroke team works rapidly to solidify the patient history, perform a focused neurologic examination and obtain necessary laboratory tests and brain imaging to accurately diagnose acute ischemic stroke and properly treat the patient...

Status epilepticus (SE) is a severe neurological condition with significant morbidity and mortality. A reliable tool for prognosis is needed to take decision regarding treatment strategies. We compared 2 available prognostic scores of outcome: the Status Epilepticus Severity Score (STESS) and the Epidemiology-based Mortality score in SE (EMSE). We included 46 patients with SE evaluated out the last 5years in our hospital. We excluded patients with postanoxic encephalopathy or incomplete data. Among the 46 patients with SE, in-hospital mortality was 28%...

BACKGROUND: The use of an automated external defibrillator (AED) prior to EMS arrival can increase 30-day survival in out-of-hospital cardiac arrest (OHCA) significantly. Drones or unmanned aerial vehicles (UAV) can fly with high velocity and potentially transport devices such as AEDs to the site of OHCAs. The aim of this explorative study was to investigate the feasibility of a drone system in decreasing response time and delivering an AED. METHODS: Data of Global Positioning System (GPS) coordinates from historical OHCA in Stockholm County was used in a model using a Geographic Information System (GIS) to find suitable placements and visualize response times for the use of an AED equipped drone...

BACKGROUND: The public commonly calls 911 for unintentional ingestions, rather than calling the local poison center. By utilizing a series of scripted questions, 911 dispatchers in Los Angeles determine if an ingestion meets "omega-1" classification. Under such circumstances, the regional poison center is contacted prior to dispatch of paramedics. If the poison center advises that the patient can remain at home, EMS is not dispatched and the patient is followed at home by the poison center...

BACKGROUND: Starch is a major part of cereal grain. It comprises two glucose polymer fractions, amylose (AM) and amylopectin (AP), that make up about 25 and 75 % of total starch, respectively. The ratio of the two affects processing quality and digestibility of starch-based food products. Digestibility determines nutritional quality, as high amylose starch is considered a resistant or healthy starch (RS type 2) and is highly preferred for preventive measures against obesity and related health conditions...
