Filter by:Greater efforts are needed to bring affordable, clean stoves and adaptive behavioral strategies to the millions of households worldwide that continue to burn solid cooking fuels using inefficient stoves. Two of the leading causes of infant mortality, preterm birth and pneumonia, are associated with high exposures to household air pollution during pregnancy and early infancy. The proposed study will assess the feasibility and acceptability of an introduced liquid petroleum gas stove, complemented by two alternative approaches to delivering tailored behavioral change interventions, among pregnant women and their neonates.
Introduction: Acute Heart Failure is frequently decompensated by pulmonary infection, but the diagnosis of pulmonary infection sometimes is difficult in these patients due to similar signals and clinical symptoms in both pathologies. Furthermore, when it is possible the diagnosis of pulmonary infection, physicians may have difficult to determine etiology and delaying antibiotic therapy. Procalcitonin (PCT) have been used like a biomarker to determine the period of use of antibiotics in patients with acute respiratory infections. It is specific for bacterial infections and it have showed as a marker of severity infection and may help to determine interruption period of antibiotic therapy in a safety way for the patient. Aim: Evaluate levels of PCT related to interruption of antibiotics in patients with decompensated acute heart failure (DAHF) with suspected bacterial pulmonary infection. Methods: In this pilot project will be included around 100 patients, randomized in two groups: group A (PCT levels may guide the interruption of antibiotic at day 5) or group B (antibiotic period will be determined by the physician without the knowledge of PCT levels). Will be collected laboratorial and clinical data at days 0,3 and 5. Both groups will be compared to evaluate PCT levels and total period of antibiotic therapy, hospitalization and readmission in 30 days. This study will determine the sensibility/specificity of PCT in patients with DAHF.
This clinical study will collect fresh samples and perform laboratory testing on fresh and archived samples as described in the protocol.
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 study will evaluate the change in gastrointestinal (GI) flora following probiotic supplementation, and expected to lead to an increase in the intestinal epithelial integrity and to improvement in its health. Concurrently with the reduction in the amount of toxins in the GI tract following an intensive exercise, a lower incidence of symptoms of discomfort will improve the quality of the training sessions which will be exhibited by an improvement in endurance capacity and in physiological responses to rigorous exercise. Half of the participants will receive probiotic supplement while the other half will receive a placebo.
Delayed prescriptions have been shown to lower antibiotic use for upper respiratory tract infections (which are mostly viral). This trial will test the hypothesis that if the clinician post-dates the delayed prescription by 2 days, rather than dating it on the day the patient is seen, there will be a further drop in the rate of antibiotic use.
The purpose of the study is to assess the short term efficacy of the Theraflu Night powder for oral solution in the Russian population in "Short term relief of the symptoms of colds, chills and influenza, including mild to moderate pain, fever and nasal congestion".
Social network targeting strategies can be used to improve the delivery and uptake of health interventions. We will enroll approximately 30,000 individuals into a randomized controlled trial of different targeting algorithms in order to explore how social network dynamics affect the uptake, diffusion, and group-level normative reinforcement of key neonatal and infant health behaviors and attitudes in 176 rural villages in the Copan region of Honduras. Our goal is to develop methods by which global health practitioners can exploit face-to-face social network interactions in order to maximize uptake of neonatal and infant health interventions. The villages will be randomly assigned to 16 cells of 11 villages each in a 2 x 8 factorial design of different targeting algorithms.
This is an open-label, randomized, single-center, 2-period, 2-sequence, single-dose crossover design study in adult male and female healthy participants. Eligible participants will receive either treatment A (reference): Fluimucil® Acetylcysteine 2% oral solution, 200 mg N- acetylcysteine (NAC) in 10 mL dose, or treatment B (test): Acetylcysteine 2% oral solution, 200 mg NAC in 10 mL dose. Blood sampling will be collected pre-dose and up to 48 hours in each period. After completion of the second study period (i.e. last pharmacokinetic (PK) sample on Day 3 of Period 2) participants will be discharged from the clinic.
Probiotics are microorganisms that are believed to provide health benefits when consumed. The term probiotic is currently used to name ingested microorganisms associated with beneficial effects to humans and animals. Probiotics are popularized in the lay literature for many different clinical problems. They have been studied in infants and children as a preventive or treatment for a variety of infections. Studies on the medical benefits of probiotics have yet to reveal a cause-effect relationship, and their medical effectiveness has yet to be conclusively proven for most of the studies conducted thus far. The putative benefit of probiotics in the prevention of infection relates to potential benefits to the innate and adaptive immune systems of infants. The goals of this investigation are to study immune system cell function and microbiome in children who are taking probiotics. To accomplish this goal, we propose a pilot study for which we will obtain blood and nasopharyngeal and stool samples prior to and post probiotic use in children greater than 12 months-36 months over a 27-38 day period
