Filter by:Cancer patients with very difficult to control symptoms at the Abbotsford (AC) and Fraser Valley (FVC) Cancer Centers are referred and admitted to the Tertiary Palliative Care Units at the Abbotsford Regional Hospital and Cancer Center(ARHCC). For symptom management, patients are sometimes given midazolam continuously through a needle placed underneath the skin. While effective in symptom management, midazolam can be sedating, leaving patients unable to interact with loved ones in their last days. This study is a pilot project. Before proceeding to a full-scale study, a "pilot study" or "feasibility study" is often carried out first to test the design of a study, the likelihood of successful recruitment or the acceptability of the intervention to potential subjects. The basic idea is to find out whether it will be practical to proceed to a larger study that will include more subjects. This type of study involves only a small number of subjects and therefore the results can only be used as a guide for further larger studies. The investigators also will determine whether palliative care cancer patients taking a medication called dexmedetomidine would have improved rousability (more easily and fully awakened) and symptom control (pain, shortness of breath, nausea or confusion) compared with those taking standard of care which is receiving the medication midazolam. The use of dexmedetomidine in other clinical situations (in the Operating Room or Intensive Care Unit where the patient can still respond to the doctor) has been shown to be effective in symptom control and to provide a better degree of rousability to patients but has not been well studied in the palliative care environment.
RATIONALE: Losartan potassium may be effective in treating pulmonary fibrosis caused by radiation therapy in patients with non-small cell lung cancer. PURPOSE: This clinical trial is studying losartan to see how well it works in treating pulmonary fibrosis caused by radiation therapy in patients with stage I, stage II, or stage III non-small cell lung cancer.
Heart failure (HF) is a disease that is caused by a reduced heart muscle function. Reduced heart muscle function can occur as a consequence of reduced pumping activity from a weak heart muscle or because of a stiff heart muscle. This study is looking at the effectiveness of Natrecor (nesiritide) in patients that require hospitalization due to worsening heart failure as a result of a stiff or thickened heart muscle. Natrecor is a man-made version of a protein that my body makes on its own and has been approved for the treatment of patients requiring hospital admission for heart failure and have shortness of breath at rest or with minimal activity. Natrecor has shown to lower the pressures in the heart and decreases the congestion in the lungs. This study is being done to see if the addition of a Natrecor to standard medical therapy for HF will improve symptoms faster or more completely than giving only the standard treatment for CHF.
This study will last for approximately 8 weeks and will involve 4 visits. The study is being carried out to validate a shortness of breath questionnaire
