Filter by:Amniotic fluid (AF) is a complex structure with a changing content by gestational time. AF pH can be affected by both maternal and fetal conditions such as preterm ruptures of membranes, prematurity and fetal distress. While fetal urine is the major content of AF since 20th gestational week, fetal lung liquid (FLL) also acts as a minor content. Secretion of FLL depends on chloride transport and postnatal clearance of FLL is provided by active reabsorption of sodium (Na) ions. Down-regulation of epithelial Na channels (ENaCs) and an increase of pulmonary compliance accompany to pulmonary adaptation developing at the first hours of life. Lower genomic expression of Na channels in airways is shown to be associated to respiratory distress syndrome (RDS) in preterm. Although pH and electrolyte value of AF is thought to be relevant to fetal and maternal conditions such as gestational age, antenatal steroids and preterm birth, there is no study about this topic in the literature.
The purpose of this study is to add further understanding to the doses of hymecromone that effectively and safely lead to the inhibition of hyaluronan synthesis. In this study we will investigate both circulating hyaluronan in the serum, as well as tissue hyaluronan, using sputum samples as a non-invasive surrogate. This is a parallel, open-label, single-center, dose-response study of hymecromone in healthy adults 18 years of age or older. Up to 18 participants will be enrolled. Participants will be treated for 4 days with study drug. Safety as well as biomarkers of pharmacokinetic and pharmacodynamic response will be monitored during therapy.
This Phase 2 Quadrivalent VLP Vaccine study is intended to replicate and extend the immunogenicity and safety results obtained in earlier Phase 1-2 and Phase 2 studies. The study is being conducted to demonstrate that the immunogenicity profile of the Quadrivalent VLP Vaccine meets the US Center for Biologics Evaluation and Research (CBER) licensure criteria. The study will also help to define the optimal dose, establish potential competitive advantages, and support the design of future studies.
The goal of this study was to identify the etiology of events and demographics of patients that experience complications requiring activation of the Rapid Response Team (RRT) during the first 24 h following anesthetic care.
To investigate the efficacy and safety of using the novel Tyto device for remote physical examination by co-investigators as compared to a standard medical physical examination by physicians.
Asthma is an important chronic disease that causes a significant public health problem and the commonest medical conditions treated in health clinics giving rise to considerable morbidity and mortality. Several studies suggested that improvement of patient knowledge has become a key component of asthma management. In the study setting the education material for Asthma patient is available however the proper cannel to deliver it to patient remains a puzzle to the researcher, therefore this study is trying to close the gap between Asthma education material and patient.The aim of the study is to investigate the effectiveness of an Asthma Education Program (AEP) result in improvement of patient's knowledge, medication adherence and inhaler technique.This is an experimental study a clinical trials. Data will be gathered utilising three an adapted instrument to assess patient knowledge of their disease, medication adherence and inhaler technique. Patients who are came to Asthma Bay in Emergency Department, Respiratory Clinic for routine follow up and admitted to ward will be recruited as study subjects. Subject who are agree to enrol in the study will be randomized into intervention and control group. Subjects in intervention group will be undergone one session of an AEP, however there are no intervention for control group but continue routinely follow up in Respiratory Clinic. To obtain the study result descriptive and inferential statistical analysis will be performed. To analyse the statistical significant of the change in patients' health outcome the pre and post of AEP independent t-test or chi-square test will be used.The expected finding of this study is to determine the effectiveness of AEP result in of patients' knowledge regarding asthma disease, medication adherence and inhaler technique, pre and post of AEP. Keywords: asthma, asthma education program.
Bronchoscopy is a method of diagnosis and treatment of common respiratory diseases and lung recognized for many years. Since the action takes place in the airways and in light of the use of sedation, when performing, the procedure requires caution to keep potent airway and breathing sufficient enough. Most of the bronchoscopy done without the aid of equipment for advanced airway protection. During the operation done monitoring hemodynamics: such as blood pressure, pulse and respiratory such as percutaneous oxygen saturation and carbon dioxide. Laryngeal Mask Airway (LMA) - is a tool that has been shown to be effective in securing of airway respiratory activity during positive-pressure ventilation. Several studies have shown that the use of LMA is a convenient and safe while performing bronchoscopy for airways and lungs. However, most of the studies were for certain patient groups such as children, immuno-compromised patients. Or benefits and safety LMA in front of intubation during bronchoscopy. Our aim to assess the safety and efficacy LMA in not mechanically ventilated patients undergoing flexible elective bronchoscopy . Another objective, to examine whether there is a special group of patients enjoy the LMA more than others. Patients will be divided randomly into two groups alternately by order, one patient study group and the next one to control. Study group : LMA is inserted under sedation and used during the procedure. Control group - performing bronchoscopy under sedation without LMA. About 50 people are needed each group.
This study is conducted to determine whether the test product (GW483100 10 mg containing montelukast sodium equivalent to 10 mg of montelukast) is bioequivalent to the reference montelukast sodium 10 mg tablets (innovator product) in healthy adult volunteers under fasting conditions. This is an open-label, balanced, randomized, single dose, two-way crossover study, enrolling 32 healthy human subjects to ensure at least 28 subjects complete the study. Each subject enrolled will participate in two treatment periods separated by a washout period of at least 7 days and no more than 14 days between dosing occasions. Total duration in the study for each subject will be approximately 7 weeks from screening to the subject's last visit.
The purpose of this study is to assess the safety, reactogenicity and immunogenicity of the investigational GSK Biologicals' GSK3277511A vaccine in adults
Background: Scoliosis is a curving of the spine. It usually happens in girls when they are children and teens. Doctors often use x-rays to diagnose it. The x-rays give low radiation. This may increase the risk that those young women get cancer later in life. Researchers want to learn more about this risk. They will look data that has already been collected. Objectives: To study cancer risks of repeated low radiation from x-rays for scoliosis. Also, to study death risks related to certain scoliosis patient characteristics. These include causes, kinds of curvature, and kinds of treatment. Eligibility: Medical records of women from past scoliosis studies. Design: This U.S. Scoliosis Cohort includes more than 5,000 women who were diagnosed between 1912 and 1965. Data were collected on these women in the 1980s and 1990s. These came from medical records, radiology log books, and x-ray films. Researchers found out where participants were, including if they were dead. Some women were given a follow-up questionnaire. Researchers want to find out where participants are today. They want to identify new deaths of participants. They want to find out their causes of death. This data will be added to other databases.
