The aim of our monocentric prospective in intention-to-treat study is to evaluate the feasibility of outpatient appendectomy for non complicated acute appendicitis.

Background: \- LIFE-Moms (Lifestyle Interventions for Expectant Moms) is a national project that is studying pregnant women who are overweight or obese. It is looking at ways they can manage their weight gain in pregnancy and how this may affect them and their babies health at b…

The present project aims to determine the underlying mechanisms for the switch from failure to thrive to excessive weight gain and hyperphagia with impaired satiety in PWS. The primary objective is to describe the evolution of circulating hormones involved in feeding and appetite…

The purpose of this study is to evaluate the impact of a bariatric surgery (gastric banding, bypass, sleeve gastrectomy) on several parameters (quality of sperm and others biological parameters, lifestyle, quality of life) involved in fertility of obese adult men.

The primary purpose of the study is to evaluate a standardized method of screening for platelet signalling defects in patients with constitutional disorders of platelet function of unknown origin. We hypothesize that such defects are under-diagnosed in patients, due to heavy work…

Suicide is known to be frequent in depression, and in most of the psychiatric diseases. But as it can occur in patients with no psychiatric illness and doesn't occur in every patients with psychiatric illness, it has to be considered henceforth as a specific vulnerability. This …

The main objective of this study is to compare the data of Hystérosalpingo-MRI with intra cavitary injection of diluted gadolinium salts with the classic hysterography, which allows to realize at once with no irradiating examination, a complete assessment of the female infertilit…

The aim of this study is to evaluate the clinical and biological behavior of full coverage restorations on teeth prepared without finish line in a prospective clinical study.

Obesity during adolescence, a critical time for bone development, may impair mineral accrual and reduce bone strength, leading to greater fracture risk during adolescence and later in life. This study seeks to determine the effect of obesity and accompanying metabolic changes (in…

The Metabolism, Infection and Immunity (MINI) Study is a longitudinal natural history study at the National Institutes of Health (NIH) that aims to define the relationship between infection, immunity and clinical decline in individuals with mitochondrial disease. Mitochondrial di…

Background: \- White blood cells called granulocytes help the body fight infection. People who have had chemotherapy or bone marrow transplants may have very low numbers of these cells. Transfusions of these cells can help improve the body's ability to fight infection. However, …

The investigators propose an innovative new model of care in which patients identified to be at high risk of hospitalization are offered care by a physician who will direct their care both in the hospital and in clinic but is able to do so because they see patients only at high r…

Researchers at Arkansas Children's Hospital Research Institute are conducting a study about mitochondrial function in children. The study involves up to 5 visits to Arkansas Children's Hospital with fasting blood draws, behavioral assessments, and/or questionnaires. This study i…

This research trial studies metabolomic and other molecular profiling to identify predictive biomarkers for radiation toxicity and survival in patients with lung or brain cancers receiving radiation therapy. Studying samples of blood, urine, and tissue from patients with lung or …

Observational, non randomized study aimed at measuring the effect of chemotherapy in the urinary concentrations of physiological modified nucleosides in 30 patients with metastatic colorectal cancer.

This post market clinical follow-up study is designed to confirm safety and performance of the Sidus Stem-Free Shoulder when used in hemi or total shoulder arthroplasty. The safety of the implant will be evaluated by monitoring the frequency and incidence of all kinds of adverse…

Breast cancers are among the cancers that metastasize the most to the skeleton. The appearance of bone metastasis, whether they are initials or during a relapse, is a turning point of the disease, due to the additional morbidity they imply (pain, pathologic fractures, hypercalcae…

Type 1 Diabetes is a multifactorial disease, with a strong genetic contribution of HLA genes, and minor contributions of many additional genes. The investigators hypothesis is that in addition to multifactorial inheritance, there are subtypes of diabetes that are caused by defect…

Dr. Rafael E de la Hoz and colleagues have performed standardized and computer-assisted readings of all chest CT scans received by WTC workers and volunteers at the Mount Sinai Medical Center between 2003 and 2016. The clinical team sought to assess all findings suggestive of air…
