Active clinical trials for "Syndrome"

The investigators will conduct genetic comparisons between Turner Syndrome (TS) patients with and without Bicuspid Aortic Valve (BAV) to identify causative agents of BAV in people with TS. The investigators will correlate the patterns and prevalence of structural heart defects in TS women with emerging molecular data to identify patients who are at high risk for cardiovascular complications

The most pervasive sensory manifestation of TS is sensory over-responsivity (SOR). SOR is defined as excessive behavioral response to commonplace environmental stimuli. SOR is an integral but poorly understood facet of the TS phenotype, one intertwined with core elements of the disorder and worse QOL. This proposal seeks to clarify the mechanistic bases of SOR in TS. Adults with with TS will be recruited 1) to complete a standardized clinical symptom assessment battery and 2) to undergo electroencephalogram (EEG), autonomic, and audio-visual monitoring during tactile and auditory stimuli paradigms, as well as at rest.

To determine the values and limitations of ECGI in guiding ablation and risk stratification in patients with BrS and Early Repolarization.

Venovenous extracorporeal membrane oxygenation (VV-ECMO) is widely used in the salvage treatment of critical acute respiratory distress syndrome (ARDS). However, reducing lung injury, accelerating lung recovery, shortening VV-ECMO support time, and decreasing complications during the treatment need further study. By changing the body position of ARDS patients, the prone position can increase the lung's dorsal ventilation and improve the lung's ventilation/blood flow ratio to improve oxygenation. Previous multicenter studies have proved that the prone position can significantly reduce the mortality of patients with moderate and severe ARDS. However, patients with severe ARDS rescue by VV-ECMO rarely combine with a prone position.On the one hand, with the support of ECMO, the patient's oxygenation will be significantly improved, and they will no longer need the assistance of a prone position. In addition, the ECMO cannula brings some challenges to implementing a prone position. Only a few cohort studies have reported that VV-ECMO combined with a prone position could improve the oxygenation index and respiratory system compliance during the late treatment period. The initial reason for PP in ARDS patients was to alleviate severe hypoxemia, as it was an efficient means to improve oxygenation in most patients. However, some patients were categorized as non-responders in the PP regarding oxygenation, which caused VV-ECMO therapy to be initiated. Should we decide to perform PP after VV-ECMO therapy no longer? This study evaluates whether early use of PP during VV-ECMO would increase the proportion of patients successfully weaned from VV-ECMO support compared with supine positioning in severe ARDS patients who received PP before ECMO.

The objective of this prospective, observational study is to determine the association between the composition of the gut microbiota and the severity and persistence of Complex Regional Pain Syndrome symptoms (Study A). The objective of Study B, a longitudinal study of microbiota biomarkers of patients with newly diagnosed CRPS is to determine if the researchers can predict which patients are more likely to recover compared to those who do not. A secondary objective of both studies is to examine cognitive flexibility in relation to outcomes (study A and B).

The measurement of the transcutaneous oxygen partial pressure (TCPO2) at exercise is, to our knowledge, the only method to estimate during the exercise the importance of ischemia segment of limb by segment of limb bilaterally and carry on. The diagnosis of thoracic outlet syndrome causing remains difficult and dependent operator in ultrasound because of the risk of false positive (loss of signal) or false negative (insufficient effort, inappropriate movement). Our main hypothesis is the existence of significant measurable ischemia in the forearm by transcutaneous oximetry during the maneuvering of the "candlestick". In the event of failure of this maneuver, the other maneuvers such as those of Wright, Roos, Tinel and Adson will be realized. In this study we want to evaluate the possibility of using dynamic transcutaneous Oximetry as a tool for evaluating ischemia in case of suspicion of thoracic outlet syndrome causing.

IRFARPC is a multicenter national registry designed to study the diagnosis and predisposing factors of subjects with an inherited increased risk for pancreatic cancer.

The study aims to investigate organ dysfunction and biomarkers in patients with suspected or verified COVID-19 during intensive care at Uppsala University Hospital.

The RASopathies are a group of developmental disorders caused by genetic changes in the genes that compose the Ras/mitogen activated protein kinase (MAPK) pathway. New RASopathies are being diagnosed frequently. This pathway is essential in the regulation of the cell cycle and the determination of cell function. Thus, appropriate function of this pathway is critical to normal development. Each syndrome in this group of disorders has unique phenotypic features, but there are many overlapping features including facial features, heart defects, cutaneous abnormalities, cognitive delays, and a predisposition to malignancies. This research study proposes to collect and store human bio-specimens from patients with suspected or diagnosed RASopathies. Once obtained, blood and/or tissue samples will be processed for: metabolic function studies, biomarkers, genetic studies, and/or the establishment of immortalized cell lines. In addition, data from the medical record (including neuropsychological evaluations) and surveys will be stored to create a longitudinal database for research conducted at CCHMC or at other research institutions.

The aim of this study is to investigate diagnostic accuracy of median nerve strain and applied pressure measurement . Idiopathic carpal tunnel syndrome patients and healthy controls will be evaluated by ultrasound. Median nerve strain, pressure applied to the skin will be measured at the proximal part of the carpal tunnel. The parameters will be compared between patients and controls, and before and after the open carpal tunnel release in the patients.
