Active clinical trials for "Acidosis"

Providing summarized information on the clinical and biochemical characteristics and types of renal tubular acidosis in children in Assiut University Childern Hospital.

Protection of brain development is a major aim in the Neonatal Intensive Care Unit. Neonatal encephalopathy (NE) occurs in 1.8 to 7.7 infants per 1000 births. Over the last six years, several randomized control trials have demonstrated that therapeutic hypothermia reduces the rate of death or disability at 18 months of age among infants who survived. However, the neurodevelopmental outcome in milder NE not treated with hypothermia remains unclear. A multicenter prospective observational study will be conducted to determine biological changes of mild neonatal encephalopathy who are not recruited for therapeutic hypothermia .

Alterations of acid-base equilibrium are very common in critically ill patients and understanding their pathophysiology can be important to improve clinical treatment.

This proposed study suggests that peripheral tissue acidosis sensed by the somatosensory system (sngceptin) would evoke the sng perception in the brain. This hypothesis is based on investigators preliminary data that the peripheral muscle acidosis will evoked the central sng perception. This proposed study also identify the detection of brain activation areas related to the peripheral muscle acidosis. Investigators will know specific brain areas related to sng perception evoked by the peripheral muscle acidosis and, accordingly, a novel mechanism and potential treatment for sng would be developed in this proposed study.

Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) denotes the use of high-flow humidified nasal oxygen system (for example Optiflow®) as an alternative ventilation modality for an anesthetized patient without spontaneous respiration. This method requires only basic airway management manoeuvres to keep the airway open and provides both stable longterm oxygenation as well as apneic ventialtion. We plan to evaluate this methods physiological performance under standardized conditions of airway management by frequent, repeated arterial blood gas analyses.

At this time, Saint Mary's Medical Center is currently in the process of implementing a standardized diabetic ketoacidosis (DKA) protocol. The first main goal of this project will be to evaluate patient outcomes to determine the effects of treating patients without a standardized protocol and to establish a baseline on how patients are being treating with DKA. The final goal of the project will be to compare outcomes of those patients not placed on the protocol to those that were treated using SMMC newly implemented DKA protocol. The overall goal of this project is to determine the benefit of an institutional DKA protocol.

The purpose of this study is to analyze the gene expression patterns associated with various microenvironmental stresses in tumors to understand their roles in tumor progression and treatment responses. To achieve this goal, we will perform gene expression analysis of the tumor samples collected from an IRB-approved study (IRB #: 4516-05-2R2) International Phase III Study of Chemoradiotherapy versus Chemoradiotherapy Plus Hyperthermia for Locally Advanced Cervical Cancer directed by Dr. Mark Dewhirst. We will correlate the gene expression signatures of different microenvironmental stresses with the measured physiological parameters to understand their role in tumor progression, treatment response and clinical outcomes.

Expanded access to DCA as continued treatment for congenital lactic acidosis.

The aim of this study is to define the incidence and nature of acidosis after major surgery using Figge's equations to directly measure acidosis. This study will also aim to compare the ability of indirect measures (base deficit, anion gap,corrected anion gap and lactate) to identify the presence of tissue acids in this population. The incidence of postoperative ketoacidosis as a contributor to tissue acidosis will be assessed through the use of point of care urinalysis.

The objective of the METINFO study is an observational single-center retrospective and descriptive study. The main objective is to estimate the real mortality rate associated to a Metformin overdose. Second objectives are to estimate the real hospitalization rate related to metformin overdose and to identify the risk factors of a metformin overdose and especially the potential correlation between metformin blood concentration and overdose severity.
