Biological Age in Children With GH Deficiency Undergoing Hormone Replacement Therapy
The primary objective of the study is to evaluate the epigenetic age in children with GH deficiency, before and after 6 months of treatment with growth hormone replacement therapy. The secondary objective is to correlate the epigenetic age with the auxometric and biochemical parameters used in the clinical-endocrinological practice. The …
Selected Immunological Indicators and Microbiota in Patients With Premature Birth and Preeclampsia
The goal is to demonstrate the relationship of the circulating pool of T-regulatory lymphocytes in the mother's peripheral blood with populations in the placentas and to compare with controls, what is the difference in the expression of individual regulatory molecules of T-regulatory lymphocytes according to new paradigms. The proportional and …
Stool Sample Collection Study
The primary objective of this study is to obtain de-identified stool specimens from participants with colonoscopic biopsy-based histopathologic diagnosis of colorectal cancer (CRC) and/or a ≥1 cm colorectal polyp/adenoma/mass found during pre-enrollment colonoscopy that is of sufficient size to require surgical excision or complex colonoscopic polypectomy. The samples will be …
PET Imaging of Fibroblast Activation in Atherosclerosis
Fibroblast activation protein (FAP) is a fibroblast-specific marker expressed in atherosclerosis, associated with endothelial-to-mesenchymal transition and a rupture-prone plaque phenotype. This study aims to evaluate in-vivo fibroblast activation in carotid and coronary atherosclerotic diseases with FAPI PET and its correlation with histological vulnerability and clinical outcome.
Drainage Fluid Biomarkers and Postoperative Gastrointestinal Dysfunction in Laparoscopic Colorectal Surgery
Postoperative gastrointestinal dysfunction (POGD), often referred to as postoperative ileus (POI) after colorectal surgery, is characterized by symptoms such as nausea, vomiting, abdominal distension, and delayed bowel movements. The incidence of this issue varies among medical institutions, impacting patient nutrition, prolonging hospital stays, and increasing healthcare costs. The complex pathogenesis …
Fluid Responsiveness Evaluation by a Non-invasive Method in Children, Extended to PREterm Infants - FRENCH-PREMA
In this study, the investigators aim to validate a non-invasive marker of fluid-responsiveness in preterm infants (term below 37 gestational week) with acute circulatory failure based on standardized abdominal compression. This would allow physicians to identify which patient could benefit from a fluid expansion, thus avoiding a potentially useless or …
ICG Anastomotic Control in Digestive System Surgery
This was a parallel single-center retrospective cohort study conducted at Linglong Yingcheng Hospital, Shandong, China. The purpose of this study was to investigate the effect of indocyanine green (ICG) on patients undergoing digestive system surgery (subtotal gastrectomy, partial hepatectomy, transverse colectomy, left colectomy, including sigmoid resection, and splenic colic resection). …
Physical Activity Monitoring in Myasthenia Gravis
The goal of this observational study is to evaluate the feasibility of using wearable sensor and digital technologies to measure motor and speech function in adults with autoimmune Myasthenia Gravis (MG). The main question[s] it aims to answer are: To measure the correlation of sensor-based measures of motor function with …
An Organoid-based Functional Precision Medicine Trial in Osteosarcoma
The purpose of this study is to examine if we can predict sensitivity of osteosarcoma to different chemotherapy agents using tissue cultures in the laboratory. We know that different chemotherapy agents can be used in the treatment, but not every sarcoma responds to them equally. It is important to understand …
The Effects of Bariatric Surgery on Kidney Oxygenation in Obese Adults With Type 2 Diabetes and Hyperfiltration
In this study the investigators will examine the effects of VAT reduction by bariatric surgery on kidney hypoxia and compare kidney oxygenation before- and after surgery in both sexes using BOLD-MRI and measures of kidney hemodynamic function. Furthermore, the investigators will assess whether kidney oxygenation is reduced in obese T2D …
