Filter by:The main purpose of this study is to review the resource utilization of severe adult H1N1 pneumonia undergoing antiviral and oxygen therapy, mechanical ventilation and support with pulmonary rescue therapies ( nitric oxide, ECMO, HFO) in critically ill patients in Winnipeg. Secondary objectives include, comparison of resource utilization to other similar disorders (viral pneumonia, bacterial pneumonia, septic shock, ARDS). The investigators will also look at the percentage of patients that required ICU care as compared to those who could be cared for on medical wards. The investigators will determine the resources used by both groups and compare. Finally the investigators will record the frequency of chronic comorbidities in hospitalized adult H1N1 patients.
Nutrient deficiency and immune dysfunction in older persons result in high prevalence of acute respiratory infection,which can lead to impaired nutritional status. The study objective was to determine the effect of multi micro-nutrient supplementation on nutritional and upper respiratory infection among apparently healthy community-dwelling elderly. The main hypothesis was whether daily multi micro-nutrient supplementation could reduce the incidence and prevalence of upper respiratory infection among apparently healthy community-dwelling older persons. Inclusion criteria were apparently independent healthy male and female older persons aged 60 years and over, not taking multi micro-nutrient supplementation over the last month. The study design was a community-based double-blind controlled trial involving 296 community-dwelling older persons aged 60 and above, in the Mampang Prapatan district, South Jakarta. Participants were randomized to receive either 40 mg elemental zinc (as gluconate), 120 mg ascorbic acid, 6 mg B-carotene, 15 mg alpha tocopherol (as d-alpha-tocopheryl acid succinate) and 400 micrograms folic acid (intervention group) or 400 mg calcium carbonate (control group). Supplements were taken daily for six months, from August 2008 to March 2009. Nutritional and health status were measured before and after supplementation. Poisson regression analysis was used to evaluate the effects of daily multi micro-nutrient supplementation on the incidence and prevalence of upper respiratory infection.
The aim of the study is to investigate whether the early introduction of maintenance bronchodilator therapy during an acute symptomatic episode of the disease shows benefits on the recovery of symptoms. It also represents an opportunity to identify COPD patients earlier in their disease state and start maintenance therapy, if appropriate.
Upper respiratory tract infections are a major source of morbidity throughout the world. Extracts of Korean red ginseng have been found to have the potential to modulate both natural and acquired immune responses. The investigators sought to examine the efficacy of an extract of Korean red ginseng in preventing colds. Therefore, the efficacy and safety of Korean red ginseng will be investigated in healthy subjects during the influenza season.
This study is addressed to patients suffering from an acute febrile upper respiratory tract infection suspected to be of viral origin. The purpose of this study is to determine the antipyretic efficacy (reduction of fever by lowering the body temperature from a raised state) of Aspirin in doses of 500 and 1000 mg (study medication) compared to the one of Paracetamol in doses of 500 and 1000 mg (comparator medication) as well as the one of Placebo (comparator medication without an active substance). Despite of its common use for fever treatment, the scientific data in adults which support the antipyretic efficacy of Aspirin are sparse. Therefore, the purpose of this study is to collect such data.
Bacteria resistant to antibiotic therapy are a major public health problem. The evolution of multi-drug resistant pathogens may be encouraged by provider prescribing behavior. Inappropriate use of antibiotics for nonbacterial infections and overuse of broad spectrum antibiotics can lead to the development of resistant strains. Though providers are adequately trained to know when antibiotics are and are not comparatively effective, this has not been sufficient to affect critical provider practices. The intent of this study is to apply behavioral economic theory to reduce the rate of antibiotic prescriptions for acute respiratory diagnoses for which guidelines do not call for antibiotics. Specifically targeted are infections that are likely to be viral. The objective of this study is to improve provider decisions around treatment of acute respiratory infections. The participants are practicing attending physicians or advanced practice nurses (i.e. providers) at participating clinics who see acute respiratory infection patients. A maximum of 550 participants will be recruited for this study. Providers consenting to participate will fill out a baseline questionnaire online. Subsequent to baseline data collection and enrollment, participating clinic sites will be randomized to the study arms, as described below. There will be a control arm, with clinic sites randomized in a multifactorial design to up to three interventions that leverage the electronic medical record: Order Sets that are triggered by EHR workflow containing exclusively guideline concordant choices (SA, for Suggested Alternatives); Accountable Justification (AJ) triggered by discordant prescriptions that populate the note with provider's rationale for guideline exceptions ; and performance feedback that benchmarks providers' own performance to that of their peers (PC, for Peer Comparison). The outcomes of interest are antibiotic prescribing patterns, including prescribing rates and changes in prescribing rates over time. The intervention period will be over one year, with a one-year follow up period to measure persistence of the effect after EHR features are returned to the original state and providers no longer receive email alerts.

The study is a clinical evaluation of an over the counter (OTC) combination product containing paracetamol (500 mg), dimethindene maleate (1 mg), phenylephrine hydrochloride (10 mg) compared to paracetamol (500 mg) alone in the treatment of nasal congestion, rhinorrhea, sneezing and other symptoms due to upper respiratory tract infection (URTI).
This study aims to answer the question whether oral vitamin D supplementation can decrease lung complications in children and adolescents with sickle cell disease. Lung complications are the leading causes of morbidity and of death in sickle cell disease. Infections and increased inflammation play important roles in the development of the lung problems in sickle cell disease. Emerging evidence shows that vitamin D helps the immune system to fight infection and to control inflammation and could potentially help prevent respiratory complications in patients with sickle cell disease. The investigators hypothesize that oral vitamin D3, 100,000 IU (2.5 mg), given once a month to a group of children and adolescents with sickle cell disease, will reduce the rate of respiratory events (infection, asthma exacerbation and acute chest syndrome) compared to the rate in a group given standard dose oral vitamin D3, 12,000 IU (0.3 mg) given once a month.

For many patients with blood cancers, stem cell transplantation from a family member or from an unrelated donor remains the only potentially curative option. Unfortunately, up to 40% of patients develop chronic lung disease after the transplant, which substantially increases the risk of death in the long-term. Currently, patients with transplant-related lung disease are treated with some combination of steroids and other immunosuppressant drugs, but only about 1 out of 5 improve. The importance of our study is that the investigators aim to prevent the development of transplant-related chronic lung disease in the first place. Because a strong risk factor for such chronic lung disease is a prior viral respiratory tract infection, the investigators think there is a window of opportunity to intervene. As soon as "cold and flu" symptoms start, the investigators will treat patients with a combination of drugs aimed at eliminating damaging immune responses triggered by the virus. In the absence of such treatment, the investigators believe these lung-damaging immune responses would persist even after the virus disappears. Our hope is that preventive treatment might avoid the development of chronic lung disease, and this would substantially increase long-term survival in our transplant patients. This is a pilot study. Once feasibility is established, the investigators will seek to expand this study into a definitive clinical trial.
