Filter by:UMPALA is a research study to look at the effect of four different, approved contraceptives on the cervical and vaginal tissues as well as on factors in the blood. Participants will have a baseline examination then receive one of four approved, marketed contraceptive products. Cervico-vaginal assessments will take place 4 weeks after contraceptive initiation and 3 months after to assess changes in mucosal safety after use of various contraceptive products in young, healthy, HIV uninfected women.
This is a non-interventional pilot study with the following objectives: - Establish scalable methodology for collection of retinal images, blood pressure (BP) and laboratory-based assessments - Compare the results of a machine-learning algorithm in predicting BP, glycated haemoglobin (HbA1c) and estimated glomerular filtration rate (eGFR) from digital retinal images with clinical and laboratory-based measures - Determine the required sample size needed to support a future study to fully validate the machine-learning algorithm
SIS has developed a software technology, based on machine learning and image processing, designed to enhance standard clinical images for the visualization of anatomical structures.
This is a national, multi-center, single-arm study, open-label to patients with symptomatic Transthyretin amyloid cardiomyopathy (ATTR-CM) who are tafamidis naïve. This study is to obtain safety, descriptive efficacy, Pharmacokinetics (PK) and Pharmacodynamics (PD) data for tafamidis orally once daily. Subject eligibility for participation in the study will receive tafamidis once daily or 12 months following the assessment as the screening and baseline, month 1, 3, 6, 9 and 12 visits (or Early Study Discontinuation).
Objective: To compare the use of autogenous bone graft versus autogenous bone graft mixed with bioactive glass bone graft in the treatment of maxillary anterior horizontal bone defects by ridge splitting technique combined with simultaneous implant placement. Materials and methods: Twenty-two patients were divided randomly into two groups; control group and study group. In control group, bone expansion was performed and autogenous bone was used to augment the intercortical bone defect. In study group, bone expansion was performed and autogenous bone mixed with bioactive glass was used to augment the intercortical bone defect. In both groups, the implants were inserted simultaneously with ridge splitting. 6 months after implant placement, the mean bone width and alveolar bone loss values were evaluated. Statistical analysis using paired Student's t- test to compare results within the same group of patients, whereas, independent samples t-test was used to compare variables between the two groups
STOP-ADHF Study: An evaluation of the safety and performance of the Cardionomic Cardiac Pulmonary Nerve Stimulation (CPNS) system in patients with acute decompensated heart failure.
Objectives: The aim of this in vivo randomized clinical trial with split-mouth design was to evaluate the clinical efficacy of one in-office application of a fluoride containing varnish and in office application of a bonding resin in adult patients presenting with dentin hypersensitivity. Materials and Methods: The study cohort consisted of 38 Caucasian outpatients, giving a total of 180 teeth were treated by fluoride varnish (FV) and 160 - by bonding agent (BA). Baseline pain in FV group was slightly higher on both scales (SCHIFF and VAS). Outcome measurements were assessed one or two weeks before product application (enrollment), at baseline at the application days (end of the run-in period: T0a, T0b, T0c), and at 1 week and at 1-2-6 months after first treatment.
Pulmonary complications after cardiac surgeries are common. It is one of the most crucial concerns of cardiac surgeons and anesthesiologists. These adverse events may vary from a mild respiratory dysfunction to acute respiratory distress syndrome (ARDS). One of the most public reasons of these complications is atelectasis that would result in hypoxia and pneumonia. Any of these adverse events rises the prevalence of morbidity and mortality. The chief inducing causes for atelectasis are CPB and dropped blood perfusion and ventilation of the lungs. The ventilation arrest is related with a high frequency of retained bronchial sections, local atelectasis, decrease in arterial O2 concentrations as a effect of surge in arteriovenous shunt, declined lung compliance, pulmonary edema and hence increased risk of nosocomial infections. Electrical Impedance Tomography (EIT) is a non-invasive, radiation-free, real time bedside imaging modality, which provide the assessment of regional gas volume and lung ventilation. EIT has been experienced in quite a lot of animal and clinical applications including optimization of mechanical ventilator strategies and recognition of respiratory adverse events. Besides, EIT has been used to recognize ideal PEEP by detection of homogenous ventilation in non-dependent and dependent lung regions. Homogeneous ventilation is key for inhibition of ventilator-induced lung injury.
The objective of this double-blind randomized clinical trial is to compare the effects of a dietary supplement based on eschscholtzia and valerian extracts to a placebo after 28 days of supplementation, in subjects suffering from sleep troubles associated with anxiety.
The aim of this study is to show that delayed umbilical cord clamping or milking of the umbilical cord in pregnant women undergoing elective cesarean delivery might have better effects than early clamping, on neonatal results without causing maternal hemorrhage or negatively affecting the neonatal outcome , and to compare the superiority of these three methods to each other.
