This is a single-arm study to evaluate safety and tolerability of oral IW-6463 in adults diagnosed with MELAS.
The investigators conducted a randomized controlled trial (parallel group study with 1:1 randomisation) comparing early cord clamping (ECC, at 60 seconds) and delayed cord clamping (DCC, at 180 seconds) in 90 cases of 'normal', two-step vaginal deliveries. DCC may result in a higher blood volume in the newborn, facilitating the maternal-placental-fetal exchange of circulating compounds, without potentially detrimental acidosis.
Evaluate the Long Term Effectiveness & Safety of the use of Carglumic Acid (Carbaglu®) in Patients with Propionic Acidemia (PA) or Methylmalonic Acidemia (MMA).
Study Title: The Impact of the pH on cardiac function in the critically ill patient Sponsor: King's College Hospital NHS Foundation Trust Chief Investigator: Dr Sancho Rodríguez-Villar IRAS Number: 227870 Hypothesis: Titration studies in animals with normal cardiac function show that a reduction in blood pH (and presumably that of the intracellular and interstitial compartments) from the normal level of 7.40 to 7.20 is associated with a rise in cardiac output. However, when blood pH is less than 7.20, cardiac output is reduced. Similar studies in humans with or without normal cardiac function have not been done, and yet blood pH at which aggressive treatment is recommended has been set at 7.20 based solely on animal experiments. The investigators hypothesize that a change in blood pH in humans will also affect cardiac function, but the level of blood pH at which this is observed might be similar or different in humans. In addition, the presence or absence of underlying cardiac disease and the type of acid-base abnormality present might modify the response of the heart to changes in blood pH. Primary Objectives: 1. Assess whether there are significant changes in cardiac function associated with changes in blood pH. 2. Relate the changes in cardiac function to the presence or absence of underlying cardiac disease. Study Design: A prospective multicenter observational study in 6 ICU´s (between two Trusts). During a year study period, a minimum of 300 patients will be recruited.
Metabolism is controlled by macro- and micronutrients. Protein-rich diets should lead to latent acidosis at tissue level with further negative implications. Food supplements with alkaline salts are available and popular pretending to prevent these changes. Within a randomized double-blind placebo-controlled trial, the investigators tested the hypotheses 1) that a 4-week protein-rich diet induces a latent tissue acidosis and 2) an alkaline supplement can compensate this. Acid-base balance and important metabolic parameters were determined before and after 4 weeks of supplementation by peripheral blood samples, indirect calorimetry and muscle microdialysis before and after a protein-rich test meal.
This is a prospective mixed-design study focused on the long-term management of propionic aciduria (PA) and methylmalonic aciduria (MMA) with N-carbamylglutamate (NCG) maintenance therapy. Treatment characteristics, clinical outcomes, and healthcare utilization data of patients diagnosed PA or MMA treated >6 months therapy with NCG are collected at baseline, 12 months, 18 months, 36 months and 54 months. Qualitative interviews with adult patients and caregivers are conducted >6 months after study enrollment to gain a better understanding of the disease burden and the treatment burden of patients and their families.
This First-in-Human (FIH) Phase 1/2 study is designed to characterize the safety, tolerability, and pharmacological activity (as assessed by biomarker measurements) and to determine the optimal dose of mRNA-3927 in participants with genetically confirmed propionic acidemia (PA). After establishing a dose with acceptable safety and pharmacodynamic (PD) response in a Dose Optimization Group (Part 1) in participants ≥1 year of age, additional participants will be enrolled into the study in a Dose Expansion Group (Part 2) to allow for further characterization of the efficacy, safety, and PD of mRNA-3927. Part 3 will evaluate the safety, efficacy and PD response of mRNA-3927 in infants (<1 year of age).
This study compares a volume targeted pressure support non-invasive ventilation with an automatic PEP regulation (AVAPS-AE mode) to a pressure support non-invasive ventilation (S/T mode) in patients with acute hypercapnic respiratory failure with acidosis. This study focuses on patients at risk of obstructive apneas or obesity-hypoventilation syndrom (BMI≥30 kg/m²). Half of participants (33 patients) will receive non invasive ventilation with AVAPS-AE mode, the other half will receive non-invasive ventilation with S/T mode.
This study will evaluate respiratory function in people with fibromyalgia and whether or not breathing patterns in this patient group can be explained by stress, emotional or biomechanical variables. In addition, examine the relationship between physical ability and lactate values.
