This study aims to evaluate the diagnosis performance of several item used for the classification, the diagnosis and the prognostic of pSS (primary Sjogren syndrome)
The prevalence of metabolic syndrome (MetS) is a health concern among Asians. Growing evidence indicates that Korean Americans had higher MetS prevalence compared to non-Hispanic Whites, but a culturally and linguistically appropriate lifestyle intervention has not been developed for Korean American middle-aged and older women. Thus, the investigators propose to develop a 4-week lifestyle intervention (Women's Active Living for Koreans (WALK) Study) to increase physical activity (PA) and reduce sedentary behavior for Korean American women.
People with POTS, autoimmune autonomic neuropathy (AAN), pure autonomic failure (PAF), SFN and Ehlers Danlos Syndrome (EDS) do not only suffer from orthostatic symptoms such as dizziness, headache, neck pain, blurred vision or (pre-) syncope. They also experience deficits in attention and concentration (more precisely deficits in selective perspective, operating speed, executive functions and memory performance) mainly in upright position. Only few studies concerning cognitive impairment in autonomic neuropathies, their frequency, aetiology and therapy exist. Many patients concerned, especially with POTS, report attention deficits and "brain fog" with problems in their everyday life and work, predominantly in upright posture. Specific symptomatic or medical therapies do not exist. Medical treatment with Modafinil is discussed and part of a current study at Vanderbilt Autonomic Dysfunction Centre (1-5). The investigators want to investigate if problems of concentration, attention and/or cognitive dysfunction exist in people with POTS, AAN, SFN and EDS compared to healthy controls (HC). Thus the investigators use detailed clinical, autonomic and neuropsychological tests in different body positions (lying, sitting and standing) as also acute therapy (leg crossing).
Polycystic Ovary Syndrome (PCOS) is a complex hormonal and metabolic disorder that has been shown to affect women's fertility. It can also share many symptoms with pre-diabetes, and women with PCOS often have an increased risk for type 2 diabetes, heart attack and stroke. This study aims to assess the feasibility and acceptability of exercise intervention and increased lifestyle physical activity to improve cardiovascular disease risk factors in women with PCOS.
Obstructive sleep apnea (OSA) has been associated with cardiac repolarization abnormalities and implicated in sudden cardiac death. A biologically plausible mechanism by which OSA exerts this lethality is by QT interval prolongation, a known marker of ventricular tachyarrhythmias (VTA) leading to cardiac death. Congenital long QT syndrome (LQTS) is a familial arrhythmogenic disorder characterized by prolonged QT interval on the electrocardiogram and increased propensity for VTA. Preliminary data identify an association of the extent of severity of OSA and progressive prolongation of the corrected QT interval in LQTS.
Background: Children with Down syndrome (DS) present with hypotonia, impaired balance and poor gross motor proficiency which lead to difficulty learning new motor skills, decreased engagement in physical activity, and limited participation in home, school, and community activities. Bicycle riding is a popular childhood activity with multiple health benefits; however, children with DS often have difficulty learning to ride a standard two-wheel bike. Purpose: The purpose of this pilot study is to determine the effectiveness of the Strider "Learn to Ride" intervention when used to teach children with DS to ride a two-wheel balance bike. Additional purposes include examining the immediate effects of the five-day "Learn to Ride" intervention on the balance of children with DS and the long-term effects of completion of the intervention on the participation and physical activity levels of children with DS. Methods: An estimated 10 children between the ages of 5 and 17 years old will be recruited to participate in this pre- post-test group design study. The participants will complete the five-day Strider "Learn to Ride" intervention under the instruction of a pediatric physical therapist. The immediate effects of the intervention on distance cycled and balance, using the Pediatric Balance Scale (PBS), will be assessed. Participation and physical activity levels will be assessed at long term follow-up using the Participation and Environment Measure for Children and Youth (PEM-CY) and a PROMIS physical activity questionnaire.
This study is intended to determine if compression garments effectively reduce pain in the treatment of tibial stress syndrome (TSS) in the military population. The study will include diagnoses of shin splints, which is medically known as tibial stress syndrome and medial tibial stress syndrome, and compare a treatment group using compression garments to a control group using passive recovery. Both groups will engage in a progressive walk-to-run program. The outcomes will be measured by comparison in pain scales pre and post treatments. The ability to perform a two mile run without pain symptoms will be assessed at the conclusion of the study by participant's self-reported evaluation. The TSS screening questionnaire will be obtained at each medical encounter to include the initial visit and follow-up visits at the four and eight week (+/- 3 days) marks. The self-reported 2-mile run evaluation is included on the TSSS questionnaire.
Platelets play a key role in the athero-thrombotic process. However, the in vivo mechanism accounting for thrombus growth at site of coronary atherosclerotic lesion has not been fully elucidated. While platelet adhesion and aggregation on the thrombogenic core of atherosclerotic plaque is an established mechanism for thrombus growth, the role of systemic factors, which may contribute to thrombus via amplification and propagation of platelet aggregation, is still to be clarified. There is a growing body of evidence that lipopolysaccharides (LPS), are implicated in athero-thrombosis. Circulating levels of endotoxins have been associated with human atherosclerosis progression, particularly in smokers or in patients with infections. Furthermore, endotoxins seem to be implicated in the thrombotic process through several mechanisms including up-regulation of macrophage tissue factor expression and amplification of platelet response upon interaction with Toll-like receptor 4. The relationship between endotoxins and platelets may be relevant in the context of acute coronary syndromes as endotoxins could locally amplify platelet-derived thrombus growth but this issue is still unexplored. Previous studies demonstrated that low-grade endotoxemia is detectable in human circulation, likely as consequence of enhanced gut permeability, and may be responsible for leucocyte-platelet aggregate and eventually thrombosis. The investigators hypothesize that low-grade endotoxemia may be observed in patients with coronary heart disease and may favor, at site of coronary unstable plaque, thrombus growth. To explore this issue, Escherichia Coli (EC)-LPS concentration and biomarkers of platelet activation will be measured in coronary thrombus and intra-coronary blood of patients with STEMI and stable angina (SA), respectively, and in peripheral circulation of both patients and controls. EC DNA will be searched in serum of all patients by polymerase chain reaction (PCR). Furthermore, to substantiate that LPS could be biologically active, immune-histochemical analysis of thrombi and in vitro studies will be performed to assess the interplay between LPS and platelet activation.
To evaluate the role of neurotrophic factors (NGF, GDNF, TRPV-1), to quantity tight junction proteins (ZO-1, occludin, claudin) and cytokines (IL-8, TNF-a, IL-1b) in the colonic mucosa of IBS patients and also clarify sex differences in the pathophysiology of IBS.
