This phase 3 clinical study is a randomized, observer-blind, comparator-controlled, multicenter study of QIVc versus a US-licensed comparator QIV in children 6 months through 47 months of age. The purpose of this study is to demonstrate that vaccination with QIVc elicits an immune response that is noninferior to that of a US-licensed comparator QIV containing the same virus strains, in children 6 months through 47 months of age.

NCT ID: NCT03240601 Completed - Clinical trials for Spinal Cord Injuries

Spinal Cord Stimulation to Augment Activity Based Therapy

Start date: July 1, 2017
Phase: N/A
Study type: Interventional

Involuntary muscle activity, often called spasticity, is a common problem following spinal cord injury (SCI) that can make it hard to move. Many things can cause spasticity including: muscle stretch, movement, or it can happen for no reason, and it is often described as an uncontrolled muscle spasm or feeling of stiffness. Drugs are typically used to treat spasticity, but they often have side effects, like muscle weakness, which can add to movement problems. Rehabilitation therapies offer alternatives to drugs for treating involuntary muscle activity, and rehabilitation can also improve daily function and quality of life. These benefits may be greater when several rehabilitation therapies are used together. Walking ability can be improved with a type of therapy called "locomotor training". This type of therapy may also have the benefit of decreasing spasticity. When locomotor training (LT) is combined with electrical stimulation, the benefits of training may be increased. In this study, investigators will use a kind of stimulation called transcutaneous spinal cord stimulation ("TSS") to stimulate participants' spinal cord nerves during locomotor training.

NCT ID: NCT03060161 Completed - Human Clinical Trials

Health in the Right Measure: Promoting Healthy Food and Regular Physical Activity Practice for UFRJ Servers

HRM
Start date: May 10, 2018
Phase: N/A
Study type: Interventional

Introduction: The epidemiological transition is one of the factors related to the increase in the prevalence of chronic noncommunicable diseases (CNCD), such as cardiovascular diseases, diabetes and cancer. Among the risks of risk to the development of CNCD are obesity, smoking, alcoholism, sedentary lifestyle and inadequate eating habits, with the last two levels having a high impact on gender and disease progression. Objectives: To promote healthy eating habits and to combat physical inactivity through nutritional monitoring and regular physical exercise, using a competition to stimulate adherence of the institution's employees. Methods: The present project is in agreement with the longitudinal study with the work of evaluation (anthropometric, body composition, laboratory and food consumption), in the eats of the times (at the beginning and end of the four-month intervention period). According to nutritional monitoring and individual guidance on regular physical exercise practice over a period of 12 weeks. Weight reduction, body fat reduction, changes in working methods and eating habits, and the relationship to routine physical activity after the intervention period, and are retested after six months. Expected results: Reduction of sedentary lifestyle, weight loss and body fat, improvement of eating habits, quality of life without working environment and health condition of the participants.

NCT ID: NCT02999958 Completed - Human Clinical Trials

Adding Antioxidants Into Human Sequential Culture Media System

Antioxidants
Start date: December 2016
Phase: N/A
Study type: Interventional

Upon collection, human oocytes are fertilized and culture up to the blastocyst stage, followed by transfer and / or cryopreservation. Culture media systems have been developed that support each step of this process. Although these culture media systems try to mimic the natural environment, several components of the in-vivo situation are not present in today´s media. One such component is anti-oxidants that may protect embryos against damage by reactive oxygen species. This investigation aims to compare blastocyst development using 2 different types of culture media systems, one of which contains antioxidants. Patients having at least eight oocytes and meeting other inclusion criteria can be included in this investigation. It is a prospective randomized multicenter study randomly dividing oocytes into two groups and assessing parameters of embryo development from fertilization up to blastocyst formation until day six. Embryos with acceptable developmental characteristics can be transferred into the uterus or cryopreserved for later use. The investigation is designed as a superiority study comparing utilization rate of blastocysts per normally fertilized oocyte using both media systems. In patients receiving embryo transfer in the fresh treatment cycle, detection of clinical pregnancy by ultrasound after 12 weeks gestation is the final endpoint of the investigation.

NCT ID: NCT02971878 Completed - Human Clinical Trials

Comparisons of Human Embryonic Development Using Single Medium With and Without the Addition of Antioxidants

Start date: November 2016

Superiority study Primary Endpoint: Good Quality Blastocysts on day 5 per allocated normally fertilized oocyte. Patients: Comparative embryo sibling study with 128 patients included.

NCT ID: NCT01640327 Completed - Influenza Clinical Trials

Safety and Immunogenicity of One Dose of Seasonal Trivalent Influenza Virus Vaccine (TIVf, Purified Surface Antigen, Inactivated, Egg Derived) in Adults Aged 18 Years and Above

Start date: July 2012
Phase: Phase 3
Study type: Interventional

This protocol was designed to evaluate the safety, clinical tolerability and immunogenicity of the Trivalent Influenza Virus Vaccine (TIVf, purified surface antigen, inactivated, egg derived), Northern Hemisphere formulation 2012/2013. The principal aim was to provide safety and immunogenicity data, in compliance to current EU Guidelines, with the intent of obtaining marketing approval of the vaccine formulation intended for use prior to the next influenza season in the Northern Hemisphere. The antibody response to each influenza vaccine antigen, was measured by hemagglutination inhibition (HI) and single radial hemolysis (SRH) at approximately 21 days postimmunization in adult and elderly subjects. The safety and immunogenicity of a single intramuscular (IM) injection of the vaccine was evaluated in compliance with the requirements of the current EU recommendations for clinical trials related to yearly licensing of influenza vaccines (CPMP/BWP/214/96).

NCT ID: NCT01455753 Completed - Influenza Clinical Trials

The Effect of Proximity on Flu-Shot Participation

Start date: October 2011
Phase: N/A
Study type: Observational

Using desk location information and employees' building entry/exit swipe card data from a company that offered a free 2-day worksite influenza vaccination clinic, we separately identify the vaccination effects of base proximity—the inverse of walking distance between one's desk and the clinic—and functional proximity—the likelihood of passing near the clinic during the course of a normal work day (ie, days when the clinic is not open).
