A Prospective Exploratory Clinical Study of Metronomic Capecitabine as Adjuvant Therapy in Locoregionally Advanced Hypopharyngeal Carcinoma
To explore whether the adjuvant therapy of metronomic capecitabine could improve the disease-free survival of locoregionally advanced hypopharyngeal carcinoma (stage IV：T4N0-1M0，anyTN2-3M0).
Detection of Peritoneal Metastasis of Gastric Cancer by Liquid Biopsy in Peripheral Blood: A Prospective Study
This study is a prospective, multi-omics, observational study aimed at detecting peritoneal metastasis of gastric cancer by combined assays for methylation of cell-free DNA (cfDNA) and other blood-based biomarkers. The study will enroll 384 participants with gastric cancer.
Evaluation of the Muscular FORCE in the Upper Limbs of Patients Presenting a Thoracic Outlet Syndrome
The thoracic outlet syndrome is a rare but debilitating pathology, responsible for upper limb pain. Its frequency is probably underestimated because of diagnostic difficulties. This syndrome encompasses several entities including compressions of neurological, venous or arterial origin. In addition to pain, the majority of patients report fatigability and loss of …
Pain in Pediatric Dentistry - a Grounded Theory Study on the Experiences of Dental Professionals and Students
This is a qualitative interview study, using Grounded Theory. The aim is to deepen our knowledge about how the dental team (dentists, dental hygienists, and dental assistants) and dental students perceive child patients' pain and how they perceive they are equipped to prevent and deal with child patients' pain and …
A Cross-Sectional Observational Study on Retained Drug Needle Fragments in People Who Use Intravenous Drugs
In addition to the well-known toxicological harms of intravenous drug (IVD) use, there can also be local tissue complications, including infections, venous sclerosis, tissue necrosis, and drug needle fragment retentions. Drug needle fragments in subcutaneous tissue may cause local symptoms (usually pain and infections), but they have also been identified …
Changes in Esophageal Distensibility With Proton Pump Inhibitors in Patients With Esophageal Eosinophilia: A Pilot Study
This pilot study will explore whether treatment of eosinophilic inflammation in the esophagus is associated with an improved distensibility of the esophagus. Furthermore, previous studies of the esophagus using EndoFlip only measured distensibility of the distal esophagus, specifically the distal esophagus and esophagogastric junction. Eosinophilia in EoE has been demonstrated …
Sonographic Parameters and Risk of Antepartum Hemorrhage in Asymptomatic Women With Placenta Previa: A Cohort Study
The aim of this study is to evaluate the effectiveness of ultrasonographic parameters (cervical length, placental thickness and distance placental edge from internal os of the cervix) in predicting the risk of antepartum hemorrhage and emergency cesarean delivery in asymptomatic women with placenta previa.
A Study to Explore the Role and Impact of Wearable Smart Devices in Perioperative NSCLC Patients
The trial was designed as a single-center non-interventional prospective observational study to explore the role and impact of wearable smart devices in perioperative NSCLC patients.
Histological Validation of dGEMRIC Indices as a Quantitative Biomarker for Cartilage Damage in the Hip Joint
In this study, the investigators seek to validate 3D model-based dGEMRIC (delayed gadolinium enhanced MRI of cartilage) values against histologic grading of cartilage quality, using osteochondral samples of the femoral head collected during hip replacement surgery.
Impact of Endometrial Compaction on Reproductive Outcomes After Cryotransfer of Euploid Embryos in a Natural Cycle
Multicenter prospective observational cohort study, comparing ongoing pregnancy rates in natural cycles for euploid embryo transfer in patients who present endometrial compaction at the time of the transfer versus those who have a stable or greater endometrial thickness with respect to the estrogenic phase.
