Active clinical trials for "Syndrome"

Polycystic ovary syndrome (PCOS) affects 10% of all women, and it usually co-exists with high levels of sex hormones called androgens, such as testosterone. Women with PCOS are at increased risk of metabolic complications such as diabetes, non-alcoholic fatty liver disease, high blood pressure and heart disease. However, very little is understood about how androgen excess may drive the metabolic complications observed in women with PCOS. Skeletal muscle is an important site of energy metabolism; increasingly, it is suspected that skeletal muscle energy balance is adversely impacted by androgens, thereby driving metabolic complications. To take this theory forward, we want to investigate the effects of androgens on muscle energy metabolism. We will perform detailed metabolic testing (including blood tests and muscle biopsies) in women with PCOS before and after taking tablets that block the action of testosterone for 28 days. In addition, we will be using a gold standard technique to see how women with PCOS metabolise fat and other nutrients by measuring markers in blood and breath samples after a breakfast test meal. This clinical research will increase our understanding of the complex relationships between hormonal abnormalities and metabolic disease in women with PCOS.

Wheat is the most important staple food consumed in the Western world and provides beneficial health effects and functional properties. Nevertheless, an increasing proportion of the general population is avoiding or reducing its consumption of wheat products due to self-reported gastrointestinal (GI) symptoms, such as patients with non-coeliac wheat sensitivity (NCWS) and/or irritable bowel syndrome (IBS). There is increasing evidence that the amylase trypsin inhibitors (ATIs), accounting for up to 15% of wheat proteins, play a role in the symptom generation in NCWS and IBS. In vitro studies showed ATIs can induce an innate immune response via direct interaction with the toll-like receptor 4 (TLR4), activating the TLR4-MD2-CD14 complex with subsequent release of pro-inflammatory cytokines. These results were confirmed in mice. Furthermore, in mice ATIs triggered intestinal epithelial lymphocytosis and barrier dysfunction, and modified microbiota composition and metabolism. Thus far, there have been no placebo-controlled studies investigating these effects of isolated ATIs in human subjects. Understanding the role of ATIs in symptom generation in NCWS and IBS patients is important to provide these patients with appropriate dietary advice, improving their quality of life and decreasing their risk of nutritional deficiencies. The investigators aim to perform a proof-of-concept study to assess the effect of ATIs on the intestinal barrier and immune function in healthy volunteers. The investigators hypothesise that the ATIs either directly affect the intestinal barrier function, or indirectly by activating an immune response via TLR4. The study conforms a randomized, double-blind, placebo-controlled, cross-over design, using healthy human volunteers (male and female), 18-65 years old. Volunteers will each undergo two test days, separated by a wash-out period of at least 4 weeks. At the test day, volunteers receive either isolated ATIs or placebo (physiological saline), ingested using a nasogastric intraduodenal feeding catheter.

High velocity nasal insufflation (HVNI), a form of HFNC that utilizes a small bore nasal cannula to generate higher velocities of gas delivery than HFNC which uses large bore cannula, has the ability to accomplish complete purge of extra thoracic dead space at flow rates of 35 litres/min and may be able to provide ventilatory support in patients with respiratory failure in addition to oxygenation support in patients with overlap syndrome. This study aims to evaluate the effectiveness of HVNI compared to NIMV in management of respiratory failure in patients with obesity hypoventilation syndrome and overlap syndrome.

Femoroacetabular impingement syndrome (FAIS) is a condition caused by an abnormal bone structure that causes the bones on either side of the hip joint to impinge on each other during certain movements, thus causing pain. This condition can be surgically treated with hip arthroscopy. For patients undergoing hip arthroscopy, there are currently two protocols related to how they may bear their weight after surgery: 1) Delayed Weightbearing: Patients use crutches and put very little weight on the surgical side. After 6 weeks, they are able to bear weight, 2) Immediate Weightbearing: Patients bear weight on the affected side, as tolerated, immediately after surgery with crutches for additional support. They are then permitted to stop using the crutches in the weeks after surgery as they feel comfortable and are stable on the operative leg. The purpose of this study is to determine whether immediate or delayed weightbearing protocols following hip arthroscopy impact patient outcomes and complication rates. Participants will be randomly allocated into one of the two aforementioned groups, and followed up for 2 years to assess function and patient-reported outcomes.

Tourette syndrome (TS) is a disabling neurodevelopmental disorder characterized by motor and phonic tics. The studies proposed in this application will explore the endocrine mechanisms underlying two of the least well-understood biological characteristics of TS, namely its marked male predominance and stress susceptibility. In particular, our exploratory studies will characterize the steroid profile in TS-affected boys and girls to identify novel potential biomarkers and therapeutic targets for this disorder.

This study aims to evaluate the effectiveness of educational innovative gamified cards about nephrotic syndrome for school age children on their outcomes and caregivers' practices

In adult patients with acute respiratory distress syndrome (ARDS), the beneficial effects of prone position (PP) have been well investigated and explored; it reduces intrapulmonary shunt (Qs/Qt) and enhances lung recruitment, modifying both lung ventilation (VA) and lung perfusion (Q) distribution, finally generating an improvement in VA/Q matching and reversing oxygenation impairment;it reduces right ventricular afterload, increase cardiac index in subjects with preload reserve and reverse acute cor pulmonale in severe ARDS patients, but in infants and children there is still a lack of clear evidence. Taken together, these effects explain why PP improves oxygenation, limits the occurrence of ventilator-induced lung injury and improves survival. Prone position is simple to perform in infants and in some neonatal and pediatric intensive care units is already commonly accomplished. However, a detailed analysis of the respective effects of high PEEP and prone position is lacking in infants/children with ARDS, while these two tools may interfere and/or act coherently. A recent multicenter, retrospective analysis of patients with pediatric acute respiratory distress syndrome (PARDS) describes how patients managed with lower PEEP relative to FIO2 than recommended by the ARDSNet model had higher mortality, suggesting that future clinical trials targeting PEEP management in PARDS are needed. We designed a physiological study to investigate the physiological effects of prone positioning on lung recruitability in infants/children with acute respiratory distress syndrome.

Objective: This study will be conducted to evaluate the effect of stress ball on symptom severity, quality of life, depression, anxiety and stress in patients with irritable bowel syndrome (IBS). Material and Method: The research will be carried out with 60 IBS patients diagnosed according to the Rome IV criteria, coming to the gastroenterology outpatient clinic of Erzurum City Hospital. Patients will be distributed to the experimental and control groups according to the randomization list prepared with the Random Allocation Software program. The patients in the experimental group will squeeze the stress ball for 10-15 minutes every day for 1 month. Stress ball application will not be applied to the patients in the control group. Patient information form, Irritable Bowel Syndrome Symptom Severity Score, Irritable Bowel Syndrome Quality of Life Scale and Depression-Anxiety-Stress Scale will be used to collect data. Chi-square test will be used in comparison of patient characteristics according to groups, t test will be used in independent groups for those with normal distribution, and Mann Whitney U test will be used for those without normal distribution. In the comparison of normally distributed data between groups, t-test will be used in independent groups and Mann-Whitney U test will be used in those that do not show normal distribution. In the comparison of normally distributed data within groups, the t-test will be used in dependent groups, and the Wilcoxon test will be used in data that do not show normal distribution.

A 12-week clinical study to evaluate the safety and efficacy of T92 in pediatric patients with Tourette Syndrome.

Irritable bowel syndrome is a functional bowel disorder that affects many Canadians. The syndrome involves abdominal pain and change in frequency or form of bowel movements, and these symptoms can lead to a decreased quality of life for patients. Primary care physicians are dissatisfied with current referral processes, and patients may wait a long time to receive the correct diagnosis. Diet is known to exacerbate symptoms of IBS. In Canada, accessing dietary treatment for IBS is a challenge due to lack of resources. Some patients lack access to dietary interventions, and others are given advice that is not evidenced based. Use of eHealth technology, such as virtual education delivered by a dietician, may allow for more widespread access to dietary interventions for IBS. Virtual education can include one on one dietary education, online group-based education, and the use of apps. Currently, there is a gap in knowledge whether dietary intervention for IBS, delivered virtually by a dietician, is effective in treating IBS.
