Problem: Postoperative wound infection following various spinal surgeries is a serious complication. The incidence of post-surgical wounds in spine surgery is high, and various researchers have reported different infection rates. In addition, increased healthcare costs, prolonged lengths of stay in hospital, and reduced quality of life as a result of surgical site infections (SSI) are also major concerns. Several methods for avoiding SSI, such as betadine irrigation, vacuum-assisted closure, and intra-wound vancomycin powder, have been used to reduce the rate of wound infection in spine surgery. Use of local vancomycin has been popular because of its protective effects and lower cost. According to some reports, prophylactic administration of intra-wound vancomycin powder before wound closure is an effective method for decreasing postoperative wound infection rates; however, other studies have revealed a non-significant effect of intra-wound vancomycin use for decreasing the postsurgical wound infection rate. Solution: Therefore, the investigators will prospectively randomize all various types of spinal surgeries to patients who will receive intrawound vancomycin powder and control group who will not receive the powder and to see it's effect in reducing the post-surgical infection.
The objective of this study is to investigate if the addition of a 12-week program of home-based high intensity interval training to a standard educational program aiming at preventing hypoglycemia episodes will restore hypoglycemia awareness in people living with type 1 diabetes and impaired awareness of hypoglycemia to a further extent than a standard educational program alone. Participants will be randomized for 12 weeks to the standard educational program with or without high intensity interval training. The Gold method will be used to identify people with impaired awareness of hypoglycemia. The educational program will consist of two education sessions on avoidance of hypoglycemia, causes of hypoglycemia, treatment (e.g. glucagon) of hypoglycemia, how to better recognize hypoglycemia symptoms, understand how to use a CGM/Flash-GM and understand CGM/Flash-GM reports to adjust insulin doses. Participants randomized to the training program will be asked to train three times per week for 12 weeks following the home-based program that will be provided to them. Participants will be asked to perform at least 2 training sessions per week (ideally all 3 sessions) with the exercise specialist on a virtual platform.
This project will assess the efficacy of an 8-week virtual exercise program on physical function offered to those with a breast cancer diagnosis currently receiving endocrine therapy. The intervention includes twice-weekly virtual group exercise classes. Participants also complete one to three independent home exercise sessions per week throughout the intervention. Testing will occur virtually at baseline, 8-weeks (at end of program) and follow-up evaluations will be performed at 16-weeks and 12- months after baseline testing. Questionnaires will be administered through REDCap. Exercise sessions and testing will be administered virtually via Zoom.
The goal of this multi-centre phase I/II open-label, single-arm study is to determine the feasibility, optimal dose, and preliminary efficacy of dexmedetomidine to manage agitated delirium among patients near the end of life followed by a palliative care provider in a non-monitored setting. Fifty patients will receive dexmedetomidine (0.4 mcg/kg/hour, titrated up to 1.0 mcg/kg/hour) subcutaneously. Feasibility (recruitment rate, cost), safety (rate of adverse events), dosing, and preliminary efficacy (agitation, delirium severity) will be measured.
This is a phase 3, multicenter, randomized, double-blind, placebo-controlled trial designed to compare the efficacy and safety of the humanized monoclonal anti CD19 antibody tafasitamab plus lenalidomide in addition to R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) versus R-CHOP in previously untreated, high-intermediate and high-risk patients with newly-diagnosed DLBCL
Estrogen Receptor (ER) is a crucial prognostic factor and treatment target in breast cancer patients. Knowledge of its status greatly influences the choice of the optimal course of treatment. Pathological evaluations of primary tumor, axillary nodes, and metastases are the only confirmatory approach to ER status determination and are limited to known and accessible sites. However, it is known that many advanced breast cancer patients harbor diseases presenting inter-tumor or temporal ER heterogeneity, as ER expression can vary between tumor foci and can evolve during treatment and at time of recurrence, hence the need for whole-body, non-invasive assessment of ER status. In the last decades, 16α-[18F]fluoroestradiol (FES) was developed and evaluated as an ER-targeting positron emission tomography (PET) tracer. FES correlated with ER expression, and recently was shown to be able to predict hormone therapy response. Our Center designed and evaluated 4-fluoro-11β-methoxy-16α-[18F]fluoroestradiol (4FMFES), a successor PET tracer for ER imaging. Paired comparison during a phase II clinical trial showed that 4FMFES produced images of better quality, with less overall non-specific signal than FES. It resulted in a significantly improved tumor contrast and tumor detectability using 4FMFES-PET leading to increased diagnosis confidence in early-stage breast cancer compared to FES-PET. Those results demonstrated that, as of now, 4FMFES-PET is the best imaging modality worldwide for whole-body ER status determination, but further validations are necessary to position this method as a standard and essential tool for breast cancer management. Like what was observed for FES-PET, preliminary data suggest that 4FMFES-PET combined with FDG-PET will yield very high sensibility for breast tumor detection, each method being complementary. In continuity with previous work, we seek to expand our clinical knowledge of this high-potential diagnostic imaging through the following main objective: Launch a phase II clinical trial to explore the full potential and benefit of 4FMFES-PET in combination with FDG-PET for advanced ER+ breast cancer patients to demonstrate it is an essential tool for cancer management. This proposed project will focus on 3 specific aims: 1. Compare and complement 4FMFES-PET with FDG-PET and conventional imaging modalities, and evaluate how they improved prognosis and staging of ER+ advanced breast cancer patients; 2. Correlate 4FMFES/FDG uptake and staging with pathological data (histology, receptor status, grade), including distal biopsy metastases sampling; 3. Correlate 4FMFES/FDG uptake and staging with longitudinal outcomes (treatment response, progression-free survival, time-to-relapse) to determine which cohort of patient benefit most from 4FMFES.
CCI-001 is a novel colchicine derivative that is being developed by PharmaMatrix Holdings Ltd. (PharmaMatrix). The drug binds to tubulin, a component of the microtubule polymers which are required for a wide range of cellular processes, perhaps most importantly, cell division and mitosis. CCI-001 has been shown to bind more strongly to β-III tubulin, a tubulin subtype which is overexpressed in many cancers. This trial is being undertaken as a first-in-human, Phase I trial in patients with recurrent and/or metastatic solid tumours. Primary Objectives are to examine the compound's safety profile, and to determine the recommended dose. Secondary Objectives are to determine the compound's pharmacokinetic parameters and to evaluate the clinical response rate and survival. Expansion cohorts in in tumour types known to be sensitive to other approved agents with similar mechanism of action will be treated at the recommended dose: transitional cell bladder cancer, pancreaticobiliary adenocarcinomas, gynecologic cancers (ovarian, cervical, endometrial), and lung adenocarcinoma.
SOCRATES is part of Boston Scientific's (BSC) Post-market surveillance system. The implementation of such systems is mandatory per local regulations such as the Regulation '(EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices' or short Medical Device Regulation (MDR). The SOCRATES design is therefore based on the BSC's commitment as well as external regulatory requirements to proactively and systematically gather, record and analyze relevant data on the quality, performance and safety of devices throughout their entire lifetime.
Brain photobiomodulation (PBM) therapy is an innovative modality for the stimulation of neural activity in order to improve brain function and is currently under investigation as a treatment for several diverse neurological disorders. Our emphasis on this study is to review the use of PBM as a treatment modality for concussions and the use of ImPACT® (Immediate Post-Concussion Assessment and Cognitive Testing) test to assess improvement in cognition and symptomatology in patients with post-concussion syndrome (PCS) treated with PBM.
Could sympathomimetics and sympatholytics drugs safe for the management of Type 2 Diabetes (T2D)? Based on recent evidence, we propose that pharmacological stimulation of Beta-3 adrenergic receptor (ADBR3) at higher doses of Mirabegron may be required to elicit changes in glycemia, but should be combined with Beta-1 adrenergic receptor (ADRB1) antagonists to suppress the unwanted effects on the cardiovascular system. Together, several results establish a previously unappreciated cross-talk between Gs-coupled ADRB1 and ADRB3 in adipose tissue for the control of glucose homeostasis. Moreover, these data suggest that antagonizing ADRB1 may be a good way to significantly lower the dose of ADRB3 agonist required for glucose control. Therefore, we believe that there are therapeutic opportunities in targeting adrenergic receptors for the treatment of T2D at least in young/middle aged people.
