Active clinical trials for "Syndrome"

Evidence has been documented for the close relationship between the arrhythmia pathogenesis and the gene expression in renin-angiotensin system. However, it remains unclear for involvement of RAS in the pathogenesis of non-familial sick sinus syndrome. The researchers thus investigated the possible relationship between non-familial sick sinus syndrome and the polymorphism and haplotype of the AGT promoter.

In the investigators study, the investigators will focus on the screening of the related proteins and miRNA to IBS in order to reveal the possible clues or molecular mechanism for this disorder.

Traditional methodological clinical and instrumental diagnostics of the lacrimal gland for the study of glandular architecture and functions are limited and include analysis of tear constituents, evaluation of apparent diffusion coefficients in magnetic resonance imaging and histopathological evaluation of lacrimal gland biopsy specimens. Confocal microscopy is a new emerging technology which is useful as a supplementary diagnostic tool for in vivo assessment of anterior-segment disorders.The use of in vivo confocal microscopy in a comparative study of the microscopic morphology of the salivary/lacrimal glands have not been reported up to date. In this study, we employ laser scanning confocal microscopy to evaluate the morphological changes of the salivary/lacrimal glands in patients with primary Sjögren's syndrome and compare the results with those of healthy control subjects.

Background：Patellofemoral pain syndrome（PFPS） is a common knee disorder characterized by anterior or retropatellar pain associated with activities that load the patellofemoral joint. Previous studies reveal that the vastus medialis obliquus（VMO） is an important dynamic medial stabilizer of the patellar. Insufficiency of the VMO leads to lateral shift of the patella and the increases the patellofemoral contact force. An in vitro study conducted by Hubbard JK. et al. claimed that there were no significant relationship between several morphologic characteristics of the VMO and the extent of patellofemoral joint deterioration. We consider that the condition might be different in vivo, so we chose ultrasonogrphy as the measurement tool to examine the morphology of the VMO in PFPS patients and healthy controls. Purpose：To determine if there are significant differences in several morphologic parameters of the VMO between patients with PFPS and healthy controls under 50. Method：31 PFPS patients and 31 matched healthy adults under 50 were recruited for the study. The HDI 5000 ultrasonography machine was used to evaluate morphologic parameters of the VMO, including the percent of patella attachment, fiber angle, the volume attached to the patella, and the change of shape of the VMO.

OBJECTIVES: I. Determine whether Cushing's syndrome and stress-induced pseudo-Cushing's syndrome can be differentiated by evaluating endogenous corticotropin-releasing hormone activity.

Irritable bowel syndrome is a functional disorder of the gastrointestinal tract diagnosed with the Rome criteria. The Rome IV criteria are based on abdominal pain symptoms and stool habits including stool frequency and stool forms [1]. They define 3 main subtypes based on symptoms: 1) IBS with diarrhea; 2) IBS with constipation: and 3) mixed symptoms of constipation and diarrhea. The IBS with diarrhea (IBS-D) subtype has the highest prevalence. Currently, treatment of IBS-D includes antidiarrheals, bile acid sequestrants, antispasmodics, tricyclic antidepressants, and FODMAP diet. However, many patients are intolerant or unresponsive to the above treatments. Outside of IBS, chronic diarrhea affects about 5% of adults. We have described a syndrome in a subset of IBS patients presenting with post prandial diarrhea, flushing and dermatographia whose symptoms are prevented by pre-treatment with combined H1 and H2 antihistamines [2]. However, the prevalence of this syndrome among the IBS + D patients is not known nor have the clinical characteristics or predictors of antihistamine responsive IBS + D been defined.

Nursing homes are a recent occurrence in Guadeloupe, and little is known about the characteristics of their residents. In Guadeloupe, in the French West Indies, nearly 1200 dependent older people are cared for in nursing homes. The aim of the KArukera Study of Aging in Nursing Homes (KASEHPAD) is to study the care pathways of dependent elderly people in nursing homes in Guadeloupe over a year. The main objective will be to obtain the annual rate of hospitalisation in this setting. The secondary objectives will be to assess hospitalisations costs, the incidence of mortality, the prevalence of geriatric syndromes, as well as the quality of life of residents and professional caregiver burnout. Ultimately, these results will be compared to a similar study in nursing homes, the KASAF study (for Karukera Study of Aging in Foster Families).

The aim of the PVCFD trial is to predict vulnerable plaque confirmed by OCT using coronary CT angiography and computational fluid dynamics in patients with acute coronary syndrome.

Intratracheal surfactant treatment is applied in Respiratory Distress Syndrome (RDS) Continious Positive Airway Pressure(CPAP) treatment. In recent clinical studies, two similar methods have been studied with a thin catheter without endotracheal intubation in the application of surfactant. In our neonatal intensive care unit, respiratory support is given with nasal CPAP and Humidified Heated High Flow Nasal Cannula (HHHFNC) instead of classical invasive (intubated) mechanical ventilation methods. In CPAP method, heated and humidified air is given a certain pressure (6-8 cmH2O), while in HHHFNC method, heated humidified air is given at a certain flow rate (6-8 L / min). This study was planned to compare the results of infants who were given surfactant with MIST (Minimal Invazive Surfactant Treatment) method under CPAP or HHHFNC support in the treatment of respiratory distress syndrome in premature babies. During surfactant application, babies will be monitored (as in all babies in the NICU) saturation, peak heart rate, perfusion index (the ratio of nonpulsatile flow in the capillary bed) and t values will be recorded. For all these reasons, monitoring of PI (Perfusion Index), PVI (plethysmographic variability index) and continuous transcutaneous PCO2 and PO2 values are of great importance for the prevention of mortality and morbidity, as well as monitoring of oxygen saturation values with pulse oximetry in premature babies. In our hospital, it was planned to take a total of 40 patients born under 32 weeks and less than 1500 grams (20 patients being in the HHHNFC, 20 patients in the CPAP group). Patients will be consecutively distributed to two groups until they reach the specified number of patients. In this study, it was aimed to monitor continuous oxygen saturation, PI, PVI, transcutaneous PO2 and PCO2 measurements just before, during and after the surfactant application and to compare the results of babies who received nCPAP and HHHFNC support. At the end of the study, all data will be entered in an SPSS (Statistical Package for the Social Sciences) file and study statistics will be made. A database will be created using SPSS software. A p value of <0.05 was determined as the limit of significance.
