Atrial Fibrillation(AF) is one of the most common abnormal heart rhythms and approximately 3% of the general population have AF. The prevalence increases with age of the population and is increased in people with diabetes, hypertension and those who are overweight. AF is a major risk factor for stroke; people with AF are five times more likely to suffer an ischaemic stroke; however this can be reduced significantly with appropriate interventions which depends on detection of the abnormal rhythm. Although the National Institute of Health and Care Excellence (NICE) currently recommends screening patients with symptoms of AF, including syncope, heart palpitations, and chest discomfort, as well as patients who have suffered a stroke or heart attack, many patients remain symptomless and are not managed for their increased stroke risk. Guidelines for AF screening include manual palpation of a peripheral pulse, followed up by an ECG for patients who have an irregular pulse. Although almost all patients with AF have an irregular pulse, only about 12 in 100 patients with an irregular pulse have AF. Use of an improved screening tool for AF could both cut down the number of people undergoing unnecessary ECGs, and also lead the way for a wider screening programme for AF. The aim of this study is to investigate the sensitivity and specificity of a new ECG like device for the detection of AF, the Plessey imPulse. Participants referred or admitted to secondary care with stroke symptoms and other indicators of increased prevalence of AF will be recruited. Participants will undergo three methods of AF screening, a peripheral pulse, a lead-one like ECG using the imPulse device, and the gold-standard for AF detection, a 12-lead ECG. By comparing to the ECG results specificity and sensitivity will be established for both methods in this population.

Syncope, a frequent reason for emergency room visits and hospitalization, is a symptom of three major etiological entities: cardiac causes, vaso-reflex causes and orthostatic hypotension. The etiological diagnosis is often uncertain and the prognostic assessment orients the outcome of the patient. The vast majority of syncope management costs are related to hospitalizations. Hospitalization in the immediate aftermath of emergency care is justified by a short-term prognosis. The current relevance of hospitalizations and the prognostic assessment of syncope is questioned.

The present research aims to collect virological and clinical data on hepatitis E virus (HEV) infections, either in acute or chronic forms of HEV infection in North-Eastern France, with liver- or non liver-related symptoms, plus data on HEV circulation in the outside environment. The purpose of this study is to improve the diagnosis and care of HEV-infected patients, as well as the preventive features to take into account in order to avoid food- and environment-borne infections. At last, we will investigate HEV molecular characteristics, with the hypothesis that some advantageous HEV strains coul be more pathogenic for some tissues and/or organs.

Since the cornea is the main responsible for the refraction of the eye, as its refractive power is greater than 70% of the total refraction of the eye, so modification of its refractive properties are used to change the optical system of the eye. Hence, laser-assisted in situ keratomileusis has become the most commonly procedure used to correct the refractive errors of the eye. The most important step in laser-assisted in situ keratomileusis is the creation of the corneal flap, which its thickness may judge the whole outcome of the surgery . So trying to minimize the variation in the thickness of the resultant flap in comparison to what planned flap thickness preoperatively become our target.

Define the frequency and survival pattern of cardiac arrests in relation to the hospital day of event and etiology of arrest.

Studying and investigating the association between dietary habits and risk factors for atherosclerotic cardiovascular diseases in Assiut governorate

Prospective, multi-center single-arm observational study A total of 100 subjects with femoropopliteal artery disease who meet all inclusion and exclusion criteria will be included. Patients will be followed clinically for 12 months after the procedure. An imaging study (duplex ultrasound, CT or catheter-based angiography) follow-up according to participating hospital's protocol will be performed at 12 months. Ankle-brachial index, symptom status and presence of stent fracture will be evaluated at 12 months.

Multicentre international prospective cohort study designed to evaluate whether preoperative presepsin (sCD14-ST) is associated with the composite endpoint: all-cause mortality and major adverse cardiovascular or cerebrovascular events (MACCE) after elevated risk non-cardiac surgery. If so: What is the optimal cut-off for presepsin to predict the composite endpoint all-cause mortality and MACCE? Does the calculated optimal cut-off improve prediction of the composite endpoint all-cause mortality and MACCE when added to clinical data and established biomarkers?

Lung cancer is one of the leading cause of cancer related death in China.Different from patients in the US, Chinese patients with lung nodules tend to be less related to smoking, and seem to be more willing to get operation despite of the doctors' suggestion of imaging surveillance. This study is designed to figure out the risk factors for Chinese lung cancer patients and evaluate the psychosocial status of inpatients with lung nodules.

In prehospital emergency setting, tracheal intubation is a frequent procedure (8% of interventions). Its objective is to control and protect upper airways and to optimize ventilation and oxygenation in patients with life-threatening distress. Intubation is a technical procedure which is associated with few difficulties with, in rare cases, the impossibility to do it. There are specificities of the out-of-hospital emergency with some risk factors that have been recognized in this context as well as the impossibility of assessing predictive factors of difficult intubation linked to the patient. The objective of the investigators was to describe the quality of tracheal intubation in prehospital emergency setting.
