The specific aim of this study is to gather data on fluid balance, intravenous medication administration, electrolyte balance, and diuretic and dialysis use in patients with acute respiratory failure who might benefit from a strategy designed to limit fluid administration.
This study aims to compare the acute effect of consuming milk and butter fortified with either vitamin D3 or 25 (OH) D3 on serum/plasma vitamin D status in humans. In addition, the effect of vitamin D3 or 25 (OH) D3 in milk and butter on certain CVD risk markers and cognitive function will be examined.
Esophageal resection becomes a routine surgical procedure in many medical centers. Usually reconstruction after esophagectomy is achieved by gastric pull-up with cervical or intrathoracic anastomosis. The only blood supply for this gastric tube is by right gastroepiploic arcade. Bad or borderline perfusion of gastric tube is the main reason for future anastomotic leaks or strictures. The investigators suggest to measure components of venous blood gases (O2, pH, CO2, lactate) from the area of future anastomosis before construction of gastric tube and just before creation of anastomosis ( after 15-30 minutes), compare the results of this analysis with systemic venous blood. The investigators suppose that elevation of acid features of blood (pH decreasing, lactate increasing etc.) as expression of tissue ischemia after gastric tube creation maybe the significant predictive sign for future anastomotic leaks or strictures. After operation the investigators plan to find relationship between the blood gas changes and rate of anastomotic leak and stricture. This is prospective study. Anticipated cohort of 50 patients
In order to reevaluate safety and efficacy of human urinary kallikrein in treating acute cerebral infarction ,a multi-center, open label , single group study was designed. Expect to enroll 60 sites and 2186 subjects. Subjects will receive kallikrein treatment according to real clinical practice (suggest above 14days treatment) and 90 days follow up
The purpose of this study is to evaluate the effects of the application of Expiratory Positive Airway Pressure (EPAP) on Dynamic Hyperinflation, dyspnea and exercise tolerance in patients with Chronic Obstructive Pulmonary Disease (COPD).
Tacrolimus is recommended to be the first line therapeutic medication within the several immunosuppressive agents when treating refractory pediatric nephrotic syndrome, because of its definite efficacy and low toxicity. But there are still some key problems which hinder the using of tacrolimus in clinic, such as its narrow therapeutic widow, great individual difference of pharmacokinetics. Routine therapeutic drug monitoring(TDM) is needed in practice. But the disadvantage of TDM is hysteresis, which could lead to treatment failure or toxicity. To find out the reasons of great pharmacokinetic difference between patients and find out the individual proper dosage before administration are important for the clinical using of tacrolimus. It is hot in research of tacrolimus in organ transplant field, such as the association between gene polymorphisms of cytochrome P-450 3A4, 3A5 and multiple drug resistant gene(MDR1) and concentration of tacrolimus. However, there is few study about pharmacogenomics and metabonomics of tacrolimus in patients of nephrotic syndrome. The aim is to study the relationships between pharmacogenomics, metabonomics of tacrolimus and its efficacy, toxicity and blood concentration in patients of nephrotic syndrome, to find out the exact dosage before administration, to provide reference to individual drug administration.
The purpose of this study is to determine whether (a) a brief alcohol intervention, (b) a brief bystander and social norms intervention, or (c) a brief alcohol and a brief bystander and social norms intervention are effective at reducing alcohol use and sexual-related behaviors among college men mandated to receive an alcohol intervention by their university.
An extended replication of Jaen & Dalton (2014), the investigators aim to investigate the role of odors and associated trigger beliefs on symptom perception and airway inflammation in individuals with asthma
A Randomized, Open-label, Single-dose, Two-way Crossover Clinical Trial to Investigate the Pharmacokinetics and Safety/Tolerability of the Combination of Gemigliptin/Metformin HCl Sustained Release 50/2000 mg(25/1000 mg x 2 tablets) in Comparison to Each Component Gemigliptin 50 mg and Metformin HCl Extended Release 2000 mg (1000 mg x 2 tablets) Administered in Healthy Male Volunteers.
This study will determine the role of the NK cells before and after bariatric surgery. The investigators selected patients with NAFLD. A Fibroscan evaluation will be assessed as a new modality to evaluate liver fibrosis.
