Filter by:Obsessive-compulsive disorder (OCD) has a lifetime prevalence of 2-3% and is a major cause of global disability. Deep brain stimulation (DBS) is an effective treatment for patients with severe, treatment-resistant forms, but access to and utilization of this therapy remains minimal despite FDA approval via HDE. The investigator's goal is to determine the neurophysiological basis of key symptom domains underlying OCD and derive individual-specific stimulation parameters to improve consistency of outcomes and facilitate outpatient therapy delivery. To do so, the investigators take advantage of key novel DBS device features, including imaging-based "inverse solutions" to determine optimal stimulation parameters, as well as on-device neural recordings that will guide therapy delivery. The investigators will recruit patients with OCD meeting established criteria for surgical evaluation. Each will be implanted with permanent DBS leads and temporary stereo-EEG (sEEG) electrodes. In the inpatient unit, the investigators will first demonstrate how these DBS leads anatomically engage these hub-like DBS target regions and physiologically affect pre-frontal networks. In the outpatient phase, the investigators implement the inverse solutions parameters in a double-blinded head-to-head trial to test whether these personalized parameter sets can reduce symptoms in the domain-specific manner in which the personalized parameters were designed. Doing so would be the first demonstration of data-derived, individual specific DBS programming. Demonstrating clinical outcomes comparable to those achieved by expert programmers but with software-generated stimulation parameters will help demystify the programming process and increase accessibility to this therapy. Finally, and critically, patients will provide chronic on-device recordings labeled with behavioral data from wearables and portables. These naturalistic data will transform the investigator's understanding of the physiological signatures of OCD and provide biomarkers of symptom severity, therapeutic response, and potentially side effects, which will guide future therapy.
Unfractioned heparin is usually given in a defined dosage during transfemoral TAVI. Activated Clotting Time (ACT) is usually used to measure the heparin effect. ACT-analysis is easy to perform at the bedside, but susceptible to interference effects. At the end of the procedure, protamine is given to reverse eventual residual heparin effect. An overdose of protamine can impair the coagulation itself. The investigators want to analyse the effect of a partial heparin reversal by ROTEM Analysis.
The research question for the current study is: Is loratadine more effective than placebo in preventing G-CSF-related bone pain during autologous hematopoetic stem cell transplant in patients with lymphoma or multiple myeloma? The hypothesis is that prophylaxis with loratadine will help prevent or reduce the severity of bone pain in this setting.
Comparison of esophagectomy with Two-field Versus Three-field lymphadenectomy in locally advanced ESCC patients after neoadjuvant therapy
This research will study natural course of dry AMD in Chinese population, screen fundus imaging indicators for patients with Chinese dry AMD, describe the clinical features of Chinese patients with dry AMD, and obtain a biological sample library of dry AMD mainly in China.
The clinical trial study is designed as a prospective, multicenter, single-group target value clinical study to evaluate the safety and efficacy of the clinical investigational product and to evaluate its performance using the above clinical trial primary endpoint and secondary endpoint indicators.
The purpose of this pilot study is to determine if azelaic acid shows potential to be an effective treatment for Central Centrifugal Cicatricial Alopecia (CCCA). In this study, the aim is to compare azelaic acid vs placebo since azelaic acid may increase anti-inflammatory effects that affect the hair growth cycle.
This is a prospective, single arm, phase II study to evaluate the efficacy and safety of Envafolimab in subjects with locally advanced/unresectable (Stage III) non-small cell lung cancer that has not progressed after prior concurrent/sequential chemoradiotherapy.
The purpose of this study is to determine whether ctDNA could help to evaluate whether to use drug adjuvant therapy after SBRT in patients with early lung cancer.
Have a comparison between pegylated recombinant human granulocyte colony stimulating factor (PEG-rhG-CSF) and recombinant human granulocyte-colony stimulating factor (rhG-CSF) for difference in efficacy of hematopoietic reconstruction after autologous peripheral blood stem cell mobilization (PBSCM) and autologous peripheral blood stem cell transplantation (APBSCT). Primary purpose: Compare the difference between PEG-rhG-CSF and G-CSF in PBSCM. Secondary purpose: Compare the difference between PEG-rhG-CSF and G-CSF in APBSCT.
