Filter by:The intent of this clinical study is to answer the questions: 1. Is the proposed treatment safe 2. Is treatment effective in improving the health of patients with human frailty syndrome.
The propose of this study is to determine whether N-acetylcysteine is effective in reversing the changes in thyroid hormones seen in critical illness, known as the low T3 syndrome.
The purpose of this study is to determine if testing patients for endothelial dysfunction will help identify which patients are more likely at risk to have another heart attack in the future. Study participants will undergo mental stress testing while at the same time being connected to a device that measures endothelial function via the Endopat device. These same participants will also undergo a sleep study via the Watchpat device.
Background: Congenital Central Hypoventilation Syndrome (CCHS) is a rare disorder of automatic control of breathing. This disease can manifest as early as birth. Patients with this disease have a fundamental lack of central drive breathing. They do not mount any responses to hypoxia or hypercapnia during sleep or wakefulness. This places them at risk of injury or death whenever they are not consciously breathing. They require lifelong assisted ventilation while sleeping, and some while awake. Progesterone is a known respiratory stimulant in normal individuals, and it has been shown in one study of 2 patients that this drug may improve CO2 responsiveness in patients with CCHS. However, this observation requires confirmation. Hypothesis: Exogenous progesterone (in oral contraception pills) will improve CO2 responsivity by hyperoxic hypercapnic ventilatory response testing, hypoxic responsivity using 5-breath nitrogen breathing, hyperoxic ventilatory response while breathing 100% oxygen, and improve spontaneous ventilation during sleep in CCHS females >15-years of age. The progesterone will also depress ventilatory response using a hyperoxia test. Study Methodology: Baseline measures of CO2 and oxygen responsivity, and spontaneous ventilation during sleep, will be performed at baseline and after 3-weeks of taking a progesterone containing oral contraceptive agent. CO2 responsivity will be measured using a hyperoxic hypercapnic ventilatory response test. Hypoxic responsivity will be measured using a 5-breath 100% nitrogen breathing test. Hyperoxic responsivity will be measured by having subjects breathe 100% oxygen for 2-minutes. Subjects will perform an overnight polysomnogram to assess adequacy of gas exchange during spontaneous breathing while asleep. A progesterone containing oral contraception pill will then be given for 3-weeks, and the above measures repeated. Serum progesterone will be measured at baseline and at the time of study.
This is a Phase 2, multicenter, open-label, single-arm, optimal dose, long-term follow-up study of monotherapy administration of rotigotine transdermal patch in adolescents with Restless Legs Syndrome (RLS). This study will assess the long-term safety and tolerability of Rotigotine treatment in adolescents with RLS.
Purpose: - identification of factors predisposing for Post-Infectious Irritable Bowel Syndrome (PI-IBS) development after an episode of traveler's diarrhea - identification of systemic (serum) and local (biopsy) changes in infectious and immunological activity during infection and correlation with Irritable Bowel Syndrome (IBS) symptoms, persisting after traveler's diarrhea Design: - 4 study visits: before traveling, 2 weeks after traveling, 6 months after traveling, 12 months after traveling - at each study visit following investigations: blood collection, stool collection, questionnaires, rectal biopsy
Respiratory distress syndrome (RDS) is common in preterm infants born at less than 32 weeks gestation; surfactant and mechanical ventilation have been the standard treatment. However, despite advances in neonatal respiratory care, a considerable number of preterm infants develop chronic lung disease, termed bronchopulmonary dysplasia (BPD), which is associated with neonatal death, prolonged neonatal intensive care stay, and impaired neurodevelopment. High-frequency oscillatory ventilation (HFOV) was developed as a new ventilation technique in the late 1970s. It was expected to result in less BPD and death as a primary model of ventilation compared to conventional ventilation (CV) in the treatment of RDS. However, there is disagreement concerning the advantage of HFOV over CV in the treatment of RDS in preterm infants regarding the prevention of death, BPD, intraventricular hemorrhage, and periventricular leucomalacia in the short term. The purpose of this study was to compare the efficacy and safety of HFOV and CV in preterm infants with severe RDS.
This is a Phase 1 study during which patients with low or intermediate-1 risk myelodysplastic syndromes (MDS) will receive investigational study drug ARRY-614. This study has 2 parts. In the first part, patients will receive increasing doses of study drug in order to achieve the highest dose of the study drug possible that will not cause unacceptable side effects. Approximately 50 patients from the US will be enrolled in Part 1 (Completed). In the second part of the study, patients will receive the best dose of study drug determined from the first part of the study and will be followed to see what side effects and effectiveness the study drug has, if any, in treating the cancer. Approximately 30 patients from the US will be enrolled in Part 2 (Completed).
This was a multicenter, open-label, dose-escalation, Phase 2A study with multiple administrations of the rotigotine transdermal system. The study was conducted in adolescent subjects (13 to <18 years of age) with idiopathic Restless Legs Syndrome (RLS).
Tyrosine is a non essential amino acid that is the precursor of the neurotransmitter, dopamine. Tyrosine is converted into Levodihydrophenylalanine (L-Dopa) and L-Dopa is subsequently and avidly converted into dopamine. It is well known that dopamine deficiency leads to the manifestations of restless legs syndrome (RLS). Studies have shown dopamine agonists and L-dopa to be effective in controlling symptoms. No studies to date have been done to determine the role of tyrosine in RLS. This open-label pilot study aims to determine the efficacy and tolerability of tyrosine in RLS, as current agents have limitations in treating RLS in addition to adding another possible agent to the investigators arsenal of treating RLS that maybe more cost efficient. In this pilot study, the dose of tyrosine will be escalated from 750 mg once daily by mouth (PO) up to 3000 mg once daily PO, as tolerated, in increments of 750 mg every week in patients who meet the inclusion criteria for RLS. Patients' symptoms will be monitored on a weekly basis for six weeks.
