Filter by:The quality of life of elderly citizens is to a great extent related to the maintenance of independence. The risk of falling and the loss of autonomy are two frequent problems associated with ageing. Although the impact of falls on functional outcomes and morbi-mortality in the elderly is well-established, the pathophysiological mechanisms underlying these falls are poorly understood. To better assess the risk of falling, numerous studies have investigated the use of dynamic and static posturography. These studies sought to characterise populations of fallers and non-fallers using parameters from postural analysis. Nonetheless, a new concept may emerge: weakening of the ankle movement muscles may be implicated in the age-related deterioration of posture. Even though it has been shown that this decrease occurs earlier and is more severe in fallers, the direct relationship between the strength of ankle movement muscles and balance parameters in elderly fallers has not yet been established. The existence of such a relationship would make it possible on the one hand to facilitate screening for those with a risk of falling, and on the other hand to enrich our understanding of the pathophysiology of the risk of falling. The perspective would therefore be to propose programmes focused on the strengthening of these deficient muscles.
The primary objective of the phase 1 portion of this study is to determine the recommended dose of bemarituzumab in combination with 5-fluorouracil, leucovorin and oxaliplatin (modified FOLFOX6) to use in the phase 2 portion of the trial.
This phase II trial studies how well nivolumab, carboplatin, and paclitaxel work in treating patients with stage III-IV head and neck squamous cell carcinoma that can be removed by surgery. Monoclonal antibodies, such as nivolumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving nivolumab, carboplatin, and paclitaxel may work better in treating patients with head and neck squamous cell carcinoma.
The study aims to test the effect a smartphone-based intervention on primary school students and their parents' attitudes towards tobacco industry and their tobacco-related communications.
The proposed research will determine the feasibility of delivering two behavioral weight loss interventions for 1 year in adults with autosomal dominant polycystic kidney disease (ADPKD) who are overweight or obese. The study will also compare these two interventions in terms of safety, acceptability, and tolerability. Last, this pilot trial will provide initial insight into a) biological changes and b) changes in kidney growth with each of the two weight loss interventions.
The purpose of this study is to examine the effects of food additives on college students with ADHD. This study could potentially answer an important question which still remains unanswered as to whether certain food additives may be able to cause cognitive and electrical activity changes in college students with and without ADHD. In this context, food additives will be artificial food coloring.
Helicobacter pylori (Hp) infection is one of the important causes of gastrointestinal diseases, including gastritis, peptic ulcer, and malignancies, nd the eradication of Hp can effectively cure or prevent these diseases. Now, owing to the increasingly serious antibiotic resistance, Hp eradication rate is, however, becoming decreased. In order to improve the eradication rate of Hp, clinicians pay great attention to choose more effective treatment. Ilaprazole Enteric-Coated Tablets is a new generation of proton pump inhibitor (PPI). Previous research found that Ilaprazole had a more prolonged half-life and higher suppression of gastric acid secretion. In addition, its metabolism is not significantly influenced by CYP2C19, compared to the available PPIs. Doxycycline is in the tetracycline antibiotic class, has a stronger antibacterial force than tetracycline and its antibacterial spectrum is basically the same as tetracycline and doxycycline, so far, it is not widely used. Preliminary observations showed that Ilaprazole/Doxycycline-based quadruple therapy was effective in treating Hp infection, with less adverse reactions and good compliance with patients. In this study, a multi-center, randomized, parallel controlled trial will be conducted in 7 hospitals in Hunan Province, China, to observe the clinical efficacy and safety of the Bismuth-containing quadruple therapy with Ilaprazole, Doxycycline, Furazolidone and Bismuth Potassium Citrate in the treatment of Hp infected duodenal ulcer. It is expected to complete 200 effective cases, including 100 cases in the experimental group and 100 cases in the control group.
The non-O blood group is a risk factor of deep vein thrombosis and recurrence of thromboembolic events, especially when associated with Factor 5 Leiden or prothrombin G20210A mutations. A recent study suggests that non-O blood group may promote portal vein thrombosis in non cirrhotic patients. In addition, in general population and chronic hepatitis C, non-O blood group combined with one or the other of the above genetic abnormalities is associated with an increased risk of liver fibrosis and accelerated fibrogenesis. The suspected mechanism could be an increased procoagulant factor VIII and an increased Willebrand plasma level, due to a low ADAMTS 13 activity, the result of which is an hypercoagulable state and a microthrombotic process. In cirrhotic patients procoagulant factors and ADAMTS 13 which are respectively increased and decreased, have be shown to be prognostic markers of hepatocellular function and portal hypertension. It has been hypothesized that the hypercoagulable state and the microthrombotic process could contribute to the worsening of the disease and enoxaparin has been shown to positively modify the prognosis of cirrhosis. The role of non-O blood group in decompensation of cirrhosis and occurrence of complications including non-tumor portal vein thrombosis has never been studied. The investigators plan a longitudinal observational study to determine the incidence of complications in alcoholic and viral cirrhosis in case of non-O blood group compared to O blood group. The aim of this study is to determine whether ABO blood group may promote complications in alcoholic or viral cirrhosis. This is an ancillary study of two national cohorts assessing natural history and hepatocellular carcinoma risk factors in alcoholic (CIRRAL) and viral (CIRVIR) cirrhosis.
To assess whether the inhalative combination of Tobramycin/Colistin is more effective in reducing Pseudomonas colony forming units (CFUs) and improvement of lung function than Colistin in mono-therapy.
The purpose of this pilot study is to evaluate the role of Mavoglurant in clarifying the neurobiology of alcoholism risk. This is a 1-site, randomized, within subjects, counterbalanced double-blind study of a single dose (200mg) of Mavoglurant and placebo.
