Filter by:Severe acute respiratory syndrome (SARS-CoV2) due to novel Coronavirus (2019-nCoV) related infection (COVID-19) is characterized by severe ventilation perfusion mismatch leading to refractory hypoxemia. To date, there is no specific treatment available for 2019-nCoV. Nitric oxide is a selective pulmonary vasodilator gas used in as a rescue therapy in refractory hypoxemia due to acute respiratory distress syndrome (ARDS). In-vitro and clinical evidence indicate that inhaled nitric oxide gas (iNO) has also antiviral activity against other strains of coronavirus. The primary aim of this study is to determine whether inhaled NO improves oxygenation in patients with hypoxic SARS-CoV2. This is a multicenter single-blinded randomized controlled trial with 1:1 individual allocation
Delirium is highly associated with adverse clinical outcomes of intensive care unit (ICU) patients, including increased cognitive impairment, duration of intubation, ICU length of stay, mortality, physical dependence, and health care costs. This randomised controlled study will firstly develop a family-supported sensory stimulation package based on the literature review as well as the findings of the cross-sectional survey and the in-depth interview. The intervention effects than will be evaluated using outcomes including delirium incidence, delirium duration, delirium severity, ICU patients' consciousness and cognitive function as well as family members' satisfaction and anxiety. This study is expected to provide evidence of the effectiveness of family-supported sensory stimulation on preventing delirium among ICU patients.
Having an aesthetic smile has become very common among patients today. Recent studies have shown that people aged 18-49 want to have whiter and brighter teeth. The demand for whitening has increased by 300% in the last 5 years. New materials and equipment have been developed to meet this demand, and various whitening techniques have been developed for use at home and in clinical practice. Determination of color in dentistry; It can be divided into two categories with the help of visual and computer-aided devices. Eye color determination is the most widely used method during the construction of a indirect restoration. The evaluation of tooth color by eye is quite subjective. Physiological variables such as external light source, experience, age and human eye fatigue, color blindness cause inadequate results. Due to interpersonal detection differences during color perception, the lack of standardization in the determination of tooth color can be improved with the use of computer-aided devices such as spectroradiometer, spectrophotometer, colorimeter and with the help of film-based photographs and digital photographs. Spectrophotometric approach; the point of view is interesting, as it allows for an objective application, regardless of the practitioner's experience. The color selection made with the use of these devices provides a potential advantage over the color selection made with the eye. Because these measurements are objective, can be counted and can be obtained faster. Although widespread uses of computer aided colorimeters and spectrophotometers have been reported in dental studies, most devices are not suitable for routine clinical use. Color analysis with these computer-aided devices may cause inaccurate results especially in the evaluation of translucent objects such as teeth. Therefore, a combination using both eyes and devices should be used.
The proper synthesis of thyroid hormones is dependent on adequate iodine supply. The mean daily iodine intake recommended by World Health Organization is 150 mg. Iodinated contrast medium (ICM) typically contains 13 500 mg of free iodine and 15-60 g of bound iodine, an amount well above acceptable upper level. In a situation of excess iodine, thyroid discontinues the release of hormones (Wolff-Chaikoff effect), which is usually transient, although can persist causing hypothyroidism. Iodine-induced hyperthyroidism (IIH), known as the Jod-Basedow phenomenon is infrequent, but elderly patients and individuals with autonomously functioning nodular goiters are at higher risk of developing this dysfunction. According to recent studies the risk of ICM-induced hyperthyroidism appears to be low. The prevalence has not been well assessed and varies from 1 % to 10 %. Currently, there are no specific guidelines concerning the prophylactic therapy of IIH. American Thyroid Association (ATA) does not recommend routine administration of antithyroid drugs before iodinated contrast medium for all patients, however, advises to consider prophylaxis in patients at high risk of developing IIH or with cardiovascular comorbidities. ATA recommends avoidance of additional iodine and administration of b-blockers alone or with antithyroid drugs as a treatment of IIH, depending on the severity of hyperthyroidism. This study was performed to evaluate the influence of ICM on thyroid status and advantages of prophylactic therapy during ICM exposure in patients with euthyroid goiter and cardiovascular comorbidities. The association between the incidence of IIH and thyroid volume was also assessed.
A pilot study of zoledronic acid as adjuvant therapy to standard anti-vascular endothelial growth factor (anti-VEGF) treatment for neovascular age-related macular degeneration (AMD).
In France, femoral neck fracture is mainly detected with interpretation of pelvis/hip X-ray imaging (French Health Authority recommandation). However, up to 10% of fractures are not identified or misdiagnosed, especially in patients admitted to the emergency department. Indeed, radiologists may be subject to excessive work, wich cause the risk of inaccurate on X-rays diagnosis. The Artificial intelligence (AI) begins study the detection of fratures on medical imaging. In this retropective study, this technology developed by GLEAMER company is tested to evaluate the detection rate of hip fracture and specifically femoral neck fracture, compared to the radiologist diagnostic, in eldery patients admitted in emergency department. AI could optimize the diagnostic performance of radiologists (increase of confidence level) and improve the efficiency of suspected fractures sorting from emergency department.
A prospective, multi-centre, interventional study. All subjects will use the study device for two weeks and the angulated handle available with the device must be used by each subject at least 10 times.
The prevalence of food allergies has increased in recent decades, ranging from 1 to 3% of the general population. According to international literature and French national surveys, nuts today represent a group of allergens often associated with severe allergic reactions. They are responsible for 18 to 40% of deaths from food-related anaphylaxis. Among all nuts, the prevalence of anacardiac allergies (mainly cashew and pistachio) continues to increase and has become a growing public health problem. Today, global production is estimated at 4.9 million tonnes of cashews and 1.1 million tonnes of pistachios. The resulting increased exposure may explain the increased prevalence of allergic reactions reported to these fruits. In addition, anaphylactic reactions to anacardiaceae are reported to be even more severe than those occurring in subjects allergic to peanuts. Cashews and pistachios are known to exhibit immunological cross-reactions with one another. In fact, they have a strong sequential homology between their storage allergens Ana o 1 / Pis v 3 (7S vicilin, 78% homology); Ana o 2 / Pis v 2 (legume 11S, 80% homology) and Ana o 3 / Pis v 1 (albumin 2S, 70% homology). For this reason, some authors talk about the cashew / pistachio syndrome and associate the two allergenic sources by considering them as one, in clinical practice. The diagnosis of allergy to nuts, and therefore to anacardiaceae, is based on a compatible clinical history, the presence of specific IgE (demonstrated by positivity to realistic skin tests and serum IgE assay), and positivity on the oral food challenge test. In clinical practice, taking into account the cashew / pistachio syndrome, when the allergy work-up for cashew is negative, allergists tend to advise to reintroduce pistachio at home, considering the two allergens as sufficiently homologous to authorize such a practice. In this context, the investigators decided to check whether this practice, which is based mainly on in vitro homologies, is risk-free, based on the clinical experience of our center.
The purpose of this study is to try to find the best dose of the new drug BAY 2433334 to give to participants and to look at how well BAY 2433334 works on top of antiplatelet therapy in patients following a recent non cardioembolic ischemic stroke which occurs when a blood clot that has not formed in the heart travelled to the brain. BAY 2433334, works by blocking a step of the blood clotting process in our body and thins the blood and is a so called oral FXIa inhibitor.
Newly diagnosed T2DM participants without hypoglycemic drugs intake were retrospective analyzed. Plasma total bile acids in fasting state (FTBAs) and other parameters were compared before and after exenatide treatment and correlation analysis between changes of FTBAs and glycemic parameters.
