Active clinical trials for "Syndrome"

The purpose of this study is to understand the experience of living with polycystic ovary syndrome (PCOS) as an active duty Service Woman. As part of a budding research program, this proposed study will lay the groundwork for future intervention studies targeting the management of PCOS in a military population.

The PaO2/FiO2 (P/F) ratio is same for all the Positive End Expiratory Pressure (PEEP) ≥ to 5. This P/F ratio misleads the severity of disease without the knowledge of set PEEP. The Oxygenation status is actually worse when the patient is using high PEEP. P/F Ratio doesn't include PEEP in the calculation.The P/F ratio doesn't show the severity of the disease appropriate for the set PEEP. PaO2/(FiO2 X PEEP) P/FP Ratio is a new Formula which addresses this gap to appropriately calculate the severity of the disease by including PEEP in the formula. This formula is used to predict mortality for different severities of ARDS.

The investigators hypothesize that the white matter of patients with obstetric antiphospholipid syndrome deteriorates over time

Obesity is associated with general low grade inflammation and, consequently, of oxidative stress that affects properties and functionality of lipoproteins. Metabolic syndrome exacerbate low grade inflammation. The intentional weight loss of at least 5% of the initial weight can modulate the pro-inflammatory state and reduce the oxidative stress related to the metabolic syndrome, thus diminishing the cardiovascular risk.

Background: A person s dental health depends on many factors. Some are social, economic, or behavioral. Some are environmental. People with Sj(SqrRoot)(Delta)gren s Syndrome have a change in the amount and quality of saliva. This may affect dental health. Researchers want to study the dental health needs of people with this and other salivary gland problems. They will compare these findings with healthy volunteers. This will help them improve health care for these groups of people. Objectives: To study dental health needs of people with salivary gland problems and healthy volunteers. To study the disparities in dental health between these groups. Eligibility: Adults 18 and older who were in a Sj(SqrRoot)(Delta)gren s Syndrome study Healthy volunteers the same age Design: Participants will take an online survey. It should take less than 30 minutes. They can skip any questions. They will be asked about dental health, general health, and well-being. Information in the survey will be kept secure.

The overall purpose of this project is to advance understanding of the neurophysiological features of Rett syndrome (RTT), MECP2 Duplication (MECP2 Dup) and RTT-related disorders (CDKL5, FOXG1) to gain insight into disease pathogenesis, with an emphasis on identifying biomarkers of disease evolution and severity. This specific study is intertwined to the core study Natural History of Rett Syndrome and Related Disorders (RTT5211), which characterizes range of clinical involvement and genotype-phenotype correlations and will provide phenotypical data for determining the clinical relevance of the neurophysiologic parameters; study subjects here are co- and primarily enrolled in RTT5211. The proposed studies will serve as basis of future translational investigations, including further refinement of biomarkers, development of outcome measures, and clinical trials per se.

Ticagrelor 90 mg twice daily treatment is recommended for 12 months in patients with acute coronary syndrome (ACS) and in patients undergoing coronary revascularization and conservative strategies. Recent data from the PEGASUS-TIMI 541 trial have shown that long-term treatment with ticagrelor reduced the risk of major cardiovascular adverse events (MACE) in stable ambulatory patients with a history of myocardial infarction. Based on these data, prolongation over 12 months of ticagrelor therapy could be indicated in selected patients; even if with such a prolongation some adverse effects on the treatment could be observed. In the PLATO2 trial, where median duration of exposure to the study drug was 277 days, the suspension of ticagrelor therapy was 7.4% in ticagrelor versus 6% in patients receiving clopidogrel ( P <0.001). Ticagrelor treatment interruption was mainly driven by non-serious adverse events occurring mainly shortly after randomization. For patients after the first year of treatment, the subsequent rate of interruption was low. These data demonstrate that adverse events considered "not serious" by traditional trial criteria may have an effect on quality of life and, therefore, can cause treatment interruption; The phenomenon emphasizes at the same time the importance of patient education and advice on timing and the nature of adverse effects in order to improve adherence. Patients in the real world may show a premature suspension rate of the drug even higher than in clinical trials. However, data from real-world patients is scarce.

Participants will be presented with a hypothetical scenario of carpal tunnel and asked to make a decision for that case.

The purpose of this protocol is to compare standard of care lung protective ventilation settings with an automated ventilator setting, called Adaptive Support Ventilation (ASV), in patients with acute respiratory distress syndrome (ARDS). This study will compare measurements (i.e. tidal volumes, driving pressure, respiratory rate (RR), compliance, peak airway pressures, plateau pressures, PEEP) with each ventilator technique, and will measure esophageal pressures to compare transpulmonary and respiratory system mechanics.

This study wants to determine the relationship between spontaneous hand gestures, stuttering and intelligibility in individuals with Down syndrome. One third of these individuals has fluency problems, such as stuttering. Gesture use appears to be a strength in individuals with Down syndrome. While they are able to compensate for their language problems, it is not clear if they also use gestures to compensate for their speech problems. Therefore, this study will observe the impact of their gesture use on the stuttering frequency/severity and on the intelligibility of children with Down syndrome. This study has three research questions. The first question is: Is there a difference in gesture use between individuals with Down syndrome who stutter and individuals with Down syndrome who do not stutter? The hypothesis is that the children who stutter will make more gestures to compensate for the fluency problems. The kind of spontaneous hand gestures will also be considered. These results will be compared to those of typical developing individuals. The second research question is: Are stuttering events that are accompanied by a gesture more intelligible than stuttering moments that are not accompanied by a gesture? Research showed that the use of signs has an positive impact on the speech intelligibility of individuals with Down syndrome. Here it is investigated if this is also true for spontaneous hand gestures. In case of better speech intelligibility it is investigated if the gain in intelligibility is caused by how recognizable the gesture is or by the effect of the gestures on speech itself. The effect of different types on the speech intelligibility of the stuttering events will also be investigated. Typically developing individuals who stutter will function as control group. The third research question is: 'Does gestural priming have an influence on the fluency of children with Down syndrome? Gestural priming is a secondary speech signal that gives feedback to the first speech signal by simultaneously mimicking the first speech signal. In this research a hand puppet will imitate the mouth movements of the participants. Next to that, the speech will be simultaneously be accompanied by beat gestures, meaningless up and downward movements. The hypothesis is that due to mirror neurons, the participants will become more fluent. Mirror neurons are neurons in the brain that can produce a neural basis for fluency by the perception of the second speech signal.
