A study of the efficacy and safety of probiotics in immunotherapy of urothelial carcinoma.

Introduction. Reflex vaso-vagal syncope (VVS) is the most frequent cause of transient loss of consciousness and it's treatment remains a challenge. Cardioneuroablation (CNA) is a relatively new and promising method, however, the optimal technique for performing CNA has not been established. Aim. To compare effectiveness of CNA performed in the right atrium (RA) versus left atrium (LA) in achieving total vagal denervation and in preventing syncope recurrences. Methods. Study group. Consecutive patients with recurrent cardioinhibitory or mixed VVS, undergoing CNA between January 2022 and February 2024 will be randomized to the RA or LA groups. CNA is performed under general anesthesia with muscle relaxation using a 3.5 mm irrigated tip contact force catheter and ablation index.The whole procedure is performed under intracardiac echocardiography (ICE) guidance. Efficacy of vagal denervation is assessed using extracardiac vagal stimulation (ECVS). Before starting RF delivery baseline electrophysiological parameters are measured. Next, baseline ECVS from the left and right jugular veins is performed. In the LA group, after gaining transseptal access under ICE guidance, an electroanatomical map of the LA is created and anatomically-based ablation of GP from the LA is performed. Firstly, septal GP are ablated and if total vagal denervation is not achieved, GP located close to left pulmonary veins are ablated. If ECVS still shows vagal response, additional RF applications are delivered in the RA. Then, final ECVS is performed and procedure is finished. In the RA group, GP located in this chamber are ablated and if ECVS shows persistent vagal response, transseptal puncture is performed and ablation in the LA is performed. Afterwards, final ECVS is performed. Duration of follow-up is two years. Patients will attend check-up visits at 3, 12 and 24 months with standard ECG, 24hr ambulatory ECG and QoL assessment. Primary endpoint is complete vagal denervation measured by ECVS (no sinus arrest and no AVB after CNA) using LA approach only versus RA approach only Secondary endpoints include final ECVS results and follow-up data - syncope/presyncope recurrences and QoL.

In patients with suspected acute stroke due to large vessel occlusion with indication for endovascular treatment, radial access is just as safe, fast, and effective as femoral access, and it improves the entire stroke treatment process.

Cancer-related fatigue (CRF) and insomnia are prevalent among cancer patients and have been linked to de-creases in quality of life and poorer overall survivorship. Currently, the mechanisms underlying CRF are not well understood, which has led to treatments that are only moderately effective. In addition, when compared to CBT-I in the general population, the treatment outcomes in CBT-I with cancer patients are subpar and, as such, this study will evaluate whether dose of CBT-I is effective in ameliorating CRF.

Alcohol use disorder (AUD) is a major health concern amongst Veterans as it causes poor health, lost days at work, impaired psychosocial functioning, and decreased quality of life. Current treatment options for AUD show limited effectiveness, which is exemplified by high relapse rates. Chronic heavy drinking results in psychological and physical distress during abstinence, including anxiety, irritability, and general discomfort, which increases the urge to drink to relieve these symptoms. The hypothesis of this study is that noninvasive vagal nerve stimulation (nVNS) can modify the perception of such inner bodily sensations of distress, and consequently reduces the drive to drink for relief. The aim of this study is to establish feasibility and acceptability of applying nVNS as a rehabilitative treatment for AUD in Veterans. The study will also evaluate the effect of nVNS on functional outcomes, quality of life, distress, and craving, and if nVNS alters neural activation patterns in brain regions involved in the perception and awareness of distress and pain.

The purpose of this study is to assess late gastro-intestinal side-effects comparing proton therapy to photon therapy in high-risk prostate cancer patients receiving whole pelvic irradiation.

The current study will evaluate the microbiome-derived therapeutic vaccine EO2040 in combination with nivolumab in patients with circulating tumor DNA-defined Minimal Residual Disease (MRD) of colorectal cancer stage II, III, or IV after completion of standard curative therapy.

Maxillo-mandibular osteotomy is a painful surgery which requires mostly opioïds use. Recent studies on maxillary and mandibular nerve blocks have suggested benefit in maxillo-facial surgery but have been poorly investigated in orthognathic surgery. This study is designed to evaluate analgesic effectiveness, through opioïds consumption, of a bilateral double ultra-sound guided nerve blocks (maxillar and mandibular nerve) in maxillo-mandibular osteotomy.

A multicenter, prospective, randomized, open-label, controlled trial to evaluate the efficacy and safety of genotype-guided targeted agents plus rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP-X) versus rituximab-cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in patients with diffuse large B-cell lymphoma

This is a two-part, randomized, double-blind, placebo-controlled, single center study to investigate the safety and tolerability of XBI-302 administered orally in healthy volunteers. The hypothesis of this study is that XBI-302 is safe and well tolerated with the proposed dosing regimens.
