Filter by:Topical Brimonidine is a well-established topical antigalucoma, ocular hypotensive therapeutic that has been in use since 1996. Brimonidine stands out among other topical ocular hypotensives in that it has a neuroprotective effect that is independent of IOP reduction. This has been demonstrated in multiple animal and human controlled studies both in vivo and in vitro. The mechanisms proposed so far to account for this neuroprotection focus mainly on molecular level antiapoptotic effects and modulation of some excitatory stimuli like glutamate. In this study we try to test the hypothesis that a positive hemodynamic profile of Brimonidine on ocular blood flow may be responsible at least in part for its unique neuroprotective effects.
Metabolic associated fatty liver disease (MAFLD) is the most common and harmful chronic liver disease, and it is increasingly diagnosed in many developed and developing countries. Previous studies suggested a significant association between hyperuricemia and MAFLD and that hyperuricemia plays a causal role in the development of MAFLD. Xanthine oxidase is a key enzyme in uric acid metabolism, and It thus can be considered as is a therapeutic target for MAFLD, so long-term urate-lowering therapy may play a role in amelioration of MAFLD by controlling uric acid levels. So, this study is conducted to assess the effect of controlling hyperuricemia using different xanthine oxidase inhibitors on amelioration of MAFLD.
This study prospectively observed the complications intended as diarrhea or sti-sis that critically ill patients developed within 7 days after ICU admission. In addition, secondary aims investigated through bioimpedenziometry the loss of lean body mass and changes in phase angle during the same period of ICU stay.

This is an observational study in which data from people with atrial fibrillation who received or are currently receiving the drug apixaban to prevent thromboembolic events (blood clots that travel through the blood stream to plug another smaller vessel) are studied. In observational studies, only observations are made without specified advice or interventions. Atrial Fibrillation (AF) is a condition of having irregular and often rapid heartbeat. AF can lead to the formation of blood clots in the heart and to embolism, a condition that happens when a blood clot travels through the blood stream to plug another smaller vessel. This can lead to serious and life-threatening conditions, such as a stroke. A stroke occurs because the brain tissue beyond the blockage no longer receives nutrients and oxygen so that brain cells die. As strokes arising from AF can involve extensive areas of the brain, it is important to prevent them. Blood clots are formed in a process known as coagulation. This is a complex series of steps that must occur in a specific sequence. Medications are already available to prevent the formation of blood clots. When taken by mouth (orally), they are known as oral anticoagulants (OACs). OACs decrease the risk of the above-mentioned serious and life-threatening conditions. The main side effect of OACs is an increase of the risk of bleeding. In the beginning, there was only one main class of OAC called vitamin k antagonists (VKAs) prescribed in usual practice. VKAs work by lowering the number of coagulation factors in the blood. Over the years, newer OAC medications have become available which act more specifically by interrupting one or more of the coagulation steps and preventing the blood from clotting. The study treatment apixaban works by blocking a very specific step in the blood clotting process, the activation of a protein called Factor Xa. Newer OACs are also called direct oral anticoagulants (DOACs). DOACs require less monitoring by doctors, but an increased risk of bleeding remains. Bleedings can be an important reason for stopping therapy. One type of bleeding called patient relevant bleeding (PRB) has not been intensely studied so far. PRB is a type of minor bleeding which is bothersome, but which does not require medical treatment as it has no important impact on a person's health. It needs to be distinguished from so called clinically relevant non-major bleeding (CRNMB). CRNMB stands for a type of bleeding which may have an important impact on a person's health and needs medical attention, but when treated, is not likely to have a negative impact on a person's health. Only limited information is available for PRB and CRNMB related to the treatment with DOACs in real-world settings. In this study, researchers want to collect more data about how often PRB and CRNMB occur in people with AF treated with apixaban. In addition, researchers want to learn how these medical problems affect the treatment with apixaban under real-world conditions. To do this, researchers will count the number of participants in usual practice - who have PRB or CRNMB and who are being treated with apixaban at the time of this ongoing study or who have recently taken this drug, but have switched to another OAC, - who have PRB or CRNMB and have decided to stop or to continue their treatment with apixaban. In addition, characteristics of each participant and the reason for continuation or discontinuation of apixaban will be collected and described. The data for this study will come from patient surveys. Besides this data collection, no further tests or examinations are planned in this study. The participants who take their apixaban treatment during this study will receive their treatments as prescribed by their doctors during routine practice according to the approved product information. The data will be from participants who will be identified for the survey using last 12-months data from the database called HealthCore Integrated Research Database (HIRD). The data will be collected for each participant for 12 months before the participant starts the survey. The study will end as soon as the planned number of surveys has been reached or at the end date of the study.
Coronary Microvascular Dysfunction has been consistently shown to play a considerable role in pathophysiology of Ischaemia with non-obstructed coronary arteries (INOCA). While the both diagnoses are individually related to remarkably worse outcome, there is no available method to simultaneously determine INOCA-CMD endotypes in vessel level, during the invasive diagnosis. The investigators hereby hypothesize that, combined intracoronary electrocardiogram (IC-ECG) (considering the high sensitivity and specificity of IC-ECG for studied vessel-territory) and intracoronary doppler can simultaneously and successfully identify vessel specific coronary microvascular dysfunction and resulting ischemia, which may potentially enable immediate diagnosis and endotyping of CMD-INOCA subgroups during the invasive assessment of first ANOCA episode, obviating the need for further ischemia-studies such es SPECT, which have considerably higher costs and lower sensitivity. Major coronary arteries of patients aged between 18 - 75 without obstructing coronary artery disease who have previously documented ischemia with non-obstructed coronary arteries (INOCA) via coronary angiogram and myocardial perfusion scan will be evaluated simultaneously with IC-ECG and intracoronary Doppler during rest and under adenosine induced hyperaemia. Performance of the combined system to identify Coronary Microvascular Dysfunction with structural and functional subgroups as defined by abnormal Coronary Flow Reserve (CFR) and Hyperemic Microvascular Resistance (HMR) and Ischemia in downstream territories of same vessel area (as defined by perfusion scan) is intended to be determined. The investigators also intend to interrogate the possible relationship between dynamic changes in IC-ECG parameters and invasively obtained intracoronary hemodynamic data.
Male self catherterisng observational study.
This study aims to assess the feasibility of assessing acute brain injury using a portable low field MRI in patients on ECMO.
The purpose of the study is to evaluate the real-time performance of a new host response test (SeptiCyte RAPID) for differentiating sepsis from non-infection/systemic inflammatory response syndrome among patients suspected of sepsis within the first 24 hours of intensive care unit (ICU) admission.
This study is a prospective, randomized, controlled trial. In this study, 30 patients who underwent endotracheal tumor resection under rigid bronchoscope or stent placement for acquired tracheoesophageal fistula were selected as the subjects. The patients were randomly divided into remazolam general anesthesia group (R group) and propofol general anesthesia control group (P group). Remazolam general anesthesia group (R group): Remazolam 0.4 mg/kg, oxycodone 0.2 mg/kg and rocuronium 0.9 mg/kg were given for anesthesia induction. Propofol general anesthesia control group (P group): Propofol 1.5mg/kg, oxycodone 0.2mg/kg and rocuronium 0.9mg/kg were given for induction of anesthesia. After induction, high-frequency jet ventilation was used in both groups, the respiratory rate was 30-60 times/min, the inspiratory-to-breath ratio was 1:2, and the driving pressure was 0.8-1.0 KPa. Group R was given remazolam 1mg/kg/h and remifentanil 6-8ug/kg/h for maintenance. Group P was given propofol 4-8 mg/kg/h and remifentanil 6-8ug/kg/h for anesthesia maintenance. The dosage of propofol or remazolam was adjusted according to BIS and intraoperative hemodynamic changes. Rocuronium bromide 10 mg was added every half hour. Intraoperative application of vasoactive drugs to maintain mean arterial pressure above 60mmHg to avoid perioperative hypotension. Blood oxygen saturation and end-tidal carbon dioxide were monitored to avoid perioperative hypoxemia and hypercapnia, and warm measures were used to maintain the patient's intraoperative body temperature above 36.0°C. After surgery, group R was treated with sugammadex sodium 2-4 mg/kg to antagonize rocuronium bromide, and 0.5 mg of flumazenil was used to antagonize remazolam by intravenous injection; group P was treated with sugammadex 2-4 mg/kg to antagonize rocuronium.
