NCT ID: NCT04814147 Recruiting - Clinical trials for Obesity-Associated Insulin Resistance

Role NLRP3 Inflammasome in Weight Loss Following Sleeve Gastrectomy in Morbidly Obese Patients

Start date: March 16, 2021
Study type: Observational

Epidemiological studies show a very rapid increase in the epidemic of obesity in the Caribbean population. 6 out of 10 adults are overweight and 1 out of 4 is obese. Most are women. Consequences : harm to health and possible reduction in life expectancy due to the association with many cardiovascular comorbidities. Adverse effects of obesity on the cardiovascular and endocrine systems are attributed a chronic low-grade inflammatory state in obese patients. Visceral adipose tissue is largely responsible for the inflammatory syndrome. Obesity can also induce the formation of multi-protein platforms called inflammasomes also activated by mitochondrial production. Morbid obesity treatment with sleeve gastrectomy is an effective long term therapeutic for weight loss but also beneficial in terms of insulin resistance and cardiovascular complications. Some patients nevertheless remain resistant to the beneficial cardio-metabolic effects of bariatric surgery. However, the mechanisms that regulate the extent of weight loss and its stabilization after bariatric surgery are still poorly understood. Our study aims to describe the evolution of postoperative weight loss and the place of preoperative inflammation in its amplitude. The hypothesis is that the level of inflammation in visceral fat before surgery determines the extent of postoperative weight loss in obese women who have undergone sleeve gastrectomy.

NCT ID: NCT04768153 Recruiting - Cancer Clinical Trials

Prioritising Prevention of COVID-19 in Persons With Cancer in the French West Indies

Start date: June 29, 2020
Study type: Observational

The public health council (Haut Conseil de Santé Publique) published a statement on 14 March 2020 relating to the management of patients with severe forms of COVID-19, stipulating specific recommendations for patients with cancer. The statement notes that patients with cancer at much higher risk (four to five times higher) of several respiratory complications, which develop very rapidly, especially if they had recently undergone surgery or chemotherapy in the previous few weeks, and that this risk could be life-threatening, on top of the cancer-related risk. In addition, the statement noted that: - COVID-19 appears to be more frequent in patients with cancer than among the general population (1% vs 0.29%) - Among those infected, the risk of severe respiratory complications requiring admission to the intensive care unit (ICU) is higher in patients with cancer than among those without (39% vs 8%, P=0.0003). - A history of chemotherapy or surgery in the previous months is an important prognostic factor for the development of severe respiratory complications (odds ratio (OR) = 5.34, P= 0.0026). - Deterioration of respiratory function occurs more quickly in patients with cancer (13 vs 43 days, hazard ratio (HR) 3.56, 95% confidence interval (CI) [1.65-7.69]). In addition, COVID-19 may lead to a change in the diagnostic and therapeutic management of patients with cancer, with potential consequences such as use of oral treatments at home, discontinuation of anticancer therapy depending on the context, or prioritization of management according to curative/palliative treatment type, age, and line of therapy. International studies previously reported the psychological repercussions of major epidemics on the emotional state. The impact of COVID-19 on patients with cancer therefore warrants evaluation, among cancer patients in the French West Indies, in the current situation of nationwide lockdown.

NCT ID: NCT04707235 Recruiting - Sickle Cell Disease Clinical Trials

ESCORT-HU Extension: European Sickle Cell Disease Cohort - Hydroxyurea - Extension Study

Start date: August 21, 2020
Study type: Observational

As safety information pertaining to the long-term use of HU remains incomplete in spite of the first safety study (ESCORT-HU), an extension of the latter is proposed. ESCORT-HU Extension study aims at evaluating the long-term safety of Siklos® focusing on some questions regarding its safety when used in current practice in adults and paediatric patients treated with Siklos® and followed for up to 5 years. The study will focus on the following concerns : occurrence and incidence of malignancies, leg ulcers, male fertility impairment and serious unexpected AEs causally related to Siklos®.

NCT ID: NCT04605250 Completed - Clinical trials for Postoperative Pulmonary Complications

Respiratory Variability for Respiratory Monitoring During the Postoperative Recovery Period

Start date: May 21, 2019
Phase: N/A
Study type: Interventional

The research consist of measuring respiratory variability of several variables of the respiratory pattern at rest and during exercise using a thoracic movement measuring technique. The objective is to confirm the ability of this technique to measure the respiratory variability in healthy subjects comparing to flow measurements by a pneumotachograph. In a second step, the thoracic movement technique is applied to measure respiratory variability before and after surgery in patients after abdominal surgery with laparotomy. The objective is to observe a decrease of variability in subjects developing or at risk to develop a postoperative pulmonary complication.

NCT ID: NCT04533152 Not yet recruiting - Diabetic Foot Ulcer Clinical Trials

Prognostic Determinants in Patients With Diabetic Foot Ulcer.

Start date: January 2021
Study type: Observational

The worse prognosis observed in patients with Diabetic Foot Ulcer (DFU) has not been fully understood. Poor prognosis may be related to other conditions (inflammation, infectious disease, cancers) further to cardiovascular disease. The aim of the study is to conduct the first prospective, observational and multi-centre cohort of patients with DFU in France, in order to evaluate the 5-years mortality rate, its causes and relevant prognostic determinants.

NCT ID: NCT04479670 Recruiting - Clinical trials for Psychological Trauma

Psychometric and Patholinguistic Assessment of Psychotrauma Related to Natural Hazards in the Commune of "Le Prêcheur"

Start date: March 26, 2021
Study type: Observational

The project is to study the evolution of mental health in a little town of the French Martinique (Le Prêcheur) by using an innovative method of analysis that combines patholinguistic and psychometric indications for patients who risk of developing psychotrauma due to a natural hazard. Investigators will gather precise and factual data concerning the psychic and mental state of the population, by collecting patients' feelings and sentiments through individual interviews and audio recordings that will be then transcribed, and analyzed, and repeated, according to a quantitative, qualitative, and prospective methodology. This research is launched in order to meet the needs expressed both by the French authorities and the population towards an optimization of crisis management.

NCT ID: NCT04470232 Recruiting - Clinical trials for Coxofemoral Pathologies

Transcultural and Psychometric Validation of SUSHI and HOOS-12 Scores in Patients With Coxofemoral Pathologies

Start date: September 11, 2020
Study type: Observational

The management of coxofemoral pathologies is constantly increasing. In addition to degenerative hip pathology, the orthopedic surgeon is now confronted with pathologies such as femoro-acetabular conflict, pathologies of the gluteus medius and pathologies of the labrum whose early management limits arthritis degeneration. These pathologies are mainly encountered in young subjects (<60 years). Self-questionnaires play an important role in understanding patients' point of view on the impact of their coxofemoral pathologies and also allow an assessment of their condition after treatment. For the evaluation of coxofemoral pathologies in the young subject (<60 years) the Super Simple Hip score (SUSHI-score) was developed and validated. In the elderly subject with hip osteoarthritis, the HOOS score has the advantage of specifically measuring pain, symptoms, function and quality of life, but is made up of 40 items and is often considered rather heavy to submit. However, it has recently been simplified and the HOOS-12 (HOOS score with 12 items) has been developed and validated. These two scores are useful in current clinical practice but they are only validated in English.

NCT ID: NCT04459169 Recruiting - Cardiac Amyloidosis Clinical Trials

Cardiac Amyloidosis : Diagnostic Using Red Flag Signals

TEAM Red Flags
Start date: September 30, 2020
Study type: Observational

Cardiac amyloidosis is an increasingly contributor of degenerative cardiac diseases. However, its frequency remains underestimated, and diagnosis is often realized at late stages of the disease. A larger use of clinical and echographic Red Flag signals during routine echocardiographic examination may enhance the identification of early stage of the disease.

NCT ID: NCT04432337 Not yet recruiting - Type 2 Diabetes Clinical Trials

Role of Type 2 Diabetes in Potentiating the Inflammatory Response Post Extracorporeal Circulation After Cardiac Surgery

Start date: April 20, 2021
Phase: N/A
Study type: Interventional

Adult cardiac surgery ensures the surgical treatment of valvular and coronary pathologies and of heart failure with the placement of ventricular assistance. Extracorporeal circulation (ECC) is one of the major technical advances associated with cardiac surgery to replace cardiac and pulmonary functions during surgery. ECC can nevertheless lead to postoperative complications, the origin of which is linked to the patient's initial contact with the circuit and membranes of the ECC. This contact triggers a series of humoral and cellular reactions that occur in the first few hours after the ECC and the inflammatory syndrome post ECC fades on its own and usually disappears between the 4th and 6th postoperative day. If the inflammatory response post ECC is most often transient, certain conditions will maintain and intensify this response at the origin of postoperative complications, possibly leading to the patient's death. Among these situations, the investigators find the notion of emergency cardiac surgery, a patient's age over 75 years and a preoperative history of decompensated heart failure, renal failure or type 2 diabetes (T2D). The inflammasome family of receptors of the nucleotide oligomerization domain (NOD) type, pyrin domain containing 3, NLRP3, is a multi-protein platform of recent discovery which plays a major role in the signaling pathways of the innate inflammatory response. The role of the activation of the NLRP3 inflammasome in cardiovascular pathologies is now well established and its metabolic priming by hyperglycemia could explain the greater seriousness of these pathologies in T2D patients due to an exacerbated inflammatory response. What is the effect of T2D status on the inflammatory response post ECC, mediated by the NLRP3 inflammasome, in patients after cardiac surgery?

NCT ID: NCT04418245 Active, not recruiting - Covid-19 Clinical Trials

CT Biomarkers Identification by Artificial Intelligence for COVID-19 Prognosis

Start date: March 1, 2020
Study type: Observational

The study hypothesis is that low-dose computed tomography (LDCT) coupled with artificial intelligence by deep learning would generate imaging biomarkers linked to the patient's short- and medium-term prognosis. The purpose of this study is to rapidly make available an early decision-making tool (from the first hospital consultation of the patient with symptoms related to SARS-CoV-2) based on the integration of several biomarkers (clinical, biological, imaging by thoracic scanner) allowing both personalized medicine and better anticipation of the patient's evolution in terms of care organization.
