Houston, TX Paid Clinical Trials

Evaluate surgical treatment outcomes and identify best practice guidelines for complex adult spinal deformity (ASD) patients, including radiographic and clinical outcomes, surgical and postoperative complications, risk factors for and revision surgery rates, and the role of standard work to improve patient outcomes and reduce surgical and postoperative complications.

Enroll-HD is a longitudinal, observational, multinational study that integrates two former Huntington's disease (HD) registries-REGISTRY in Europe, and COHORT in North America and Australasia-while also expanding to include sites in Latin America. More than 30,000 participants have now enrolled into the study. With annual assessments and no end date, Enroll-HD has built a large and rich database of longitudinal clinical data and biospecimens that form the basis for studies developing tools and biomarkers for progression and prognosis, identifying clinically-relevant phenotypic characteristics, and establishing clearly defined endpoints for interventional studies. Periodic cuts of the database are now available to any interested researcher to use in their research - visit www.enroll-hd.org/for-researchers/access-data/ to learn more. Read Less

The objectives of this post market registry are to evaluate the safety and durability of treatment effect up to 3 years following cross-linking performed with Photrexa Viscous (riboflavin 5'- phosphate in 20% dextran ophthalmic solution), Photrexa (riboflavin 5'- phosphate ophthalmic solution), and the KXL System in patients with corneal ectasia following refractive surgery.

Cervical spine injuries (CSI) are serious, but rare events in children. Spinal precautions (rigid cervical collar and immobilization on a longboard) in the prehospital setting may be beneficial for children with CSI, but are poorly studied. In contrast, spinal precautions for pediatric trauma patients without CSI are common and may be associated with harm. Spinal precautions result in well-documented adverse physical and physiological sequelae. Of substantial concern is that the mere presence of prehospital spinal precautions may lead to a cascade of events that results in the increased use of inappropriate radiographic testing in the emergency department (ED) to evaluate children for CSI and thus an unnecessary, increased exposure to ionizing radiation and lifetime risk of cancer. Most children who receive spinal precautions and/or are imaged for potential CSI, and particularly those imaged with computed tomography (CT), are exposed to potential harm with no demonstrable benefit. Therefore, there is an urgent need to develop a Pediatric CSI Risk Assessment Tool that can be used in the prehospital and ED settings to reduce the number of children who receive prehospital spinal precautions inappropriately and are imaged unnecessarily while identifying all children who are truly at risk for CSI.

The goals of this study are to determine the feasibility and efficacy of a brief, single-session cognitive-behavioral intervention for reducing preoperative and postoperative anxiety and for determining satisfaction with the delivery process in pregnant women scheduled for Cesarean delivery due to complications with their pregnancy. This will be done through a combination of psychoeducation and exposure therapy, where the participants will be walked through the steps of a Cesarean delivery in an operating room that mimics where the patient would actually be delivering. Follow-up will occur during the immediate and extended postpartum periods to determine satisfaction and levels of anxiety. Read Less

The goal of this study is to evaluate the utility and efficacy of an artificial intelligence (AI) model at identifying structures and phases of surgery compared to traditional white light assessment by trained surgeons. Surgeons will perform the procedure in their standard practice, while the AI model analyzes data from the laparoscopic camera. Surgeons will be asked to audibly state when they identify structures and enter different phases of the surgical procedure. The AI will not alter the surgeon's view or be visible to the surgeon, and the surgeon will perform the procedure in the exact same fashion as they typically do. Read Less

An open label single-arm clinical trial to evaluate the safety, tolerability, PK, PD, and preliminary efficacy of HMPL-306 in subjects with advanced relapsed, refractory, or resistant hematological malignancies that harbor IDH mutations. Read Less

Background: Lymph node status is an important prognostic parameter in esophageal carcinoma and an independent predictor of survival. Distribution of metastatic lymph nodes may vary with tumor location, tumor histology, tumor invasion depth and neoadjuvant therapy. Surgical strategy depends on the distribution pattern of nodal metastases but consensus on the extent of lymphadenectomy differs worldwide. Especially for adenocarcinoma the distribution of lymph node metastases has not yet been described in large series. Aim of the present study is to evaluate the distribution of lymph node metastases in esophageal carcinoma specimens following transthoracic esophagectomy with at least a 2-field lymphadenectomy. Methods: The TIGER-study is a multinational observational cohort study. All patients with a resectable esophageal or gastro-esophageal junction carcinoma in whom a transthoracic esophagectomy with a 2- or 3-field lymphadenectomy is performed in participating centers will be included. All lymph node stations will be excised and separately sent for pathological examination. Cluster analysis will be performed to identify patterns of metastases in relation to tumor location, tumor histology, tumor invasion depth and neoadjuvant therapy. Conclusion: TIGER will provide a roadmap of the location of lymph node metastases in relation to tumor histology, tumor location, invasion depth, number of lymph nodes and lymph node metastases, pre-operative diagnostics, neo-adjuvant therapy and survival. Patient-tailored treatment can be developed on the basis of these results, such as the the optimal radiation field and extent of lymphadenectomy based on the primary tumor characteristics. Read Less

Urea cycle disorders (UCD) are a group of rare inherited metabolism disorders. Infants and children with UCD commonly experience episodes of vomiting, lethargy, and coma. The purpose of this study is to perform a long-term analysis of a large group of individuals with various UCDs. The study will focus on the natural history, disease progression, treatment, and outcome of individuals with UCD. Read Less

Some people who have what doctors currently call schizophrenia or bipolar disease may actually have a brain disease caused by auto-antibodies. Auto-antibodies are produced when the normal defense mechanism of the body goes wrong and begins to attack the body, similar to "friendly fire." Auto-antibodies attack brain receptors and then the person who has this problem begins to have hallucinations and other manifestations of schizophrenia, like feeling that people can see what they are thinking and also feeling that other people do not like them. If this disease is caused by auto-antibodies, typically the person is well until they are 15 years of age or older, but seldom older than 35 years. Then, in a matter of a few months they begin to have hallucinations and the other symptoms. Doctors still do not know whether some people with schizophrenia or bipolar disease have auto-antibodies attacking their brain. For this reason, in this study some of these patients will receive a treatment that suppresses the auto-antibodies and their symptoms after treatment will be compared with the symptoms of a group of similar patients who are given a preparation that looks like the real treatment, but it is not.
