Patent foramen ovale (PFO) is a prevalent cause of ischemic stroke and transient ischemic attack (TIA) in young patients. Its role as a cause of cerebrovascular events in the older population is more controversial because of other competing causes are more frequent in the elderly. Recent randomized controlled trials (RCTs) have shown that PFO closure is associated with a 59% relative risk reduction in the risk of recurrent ischemic stroke. As such, the number of PFO closure procedures are expected to increase substantially in the upcoming years. Real world data (RWD) informing on the medical management, the risk of stroke recurrence, incident atrial fibrillation, and other outcomes in stroke patients with PFO, with and without PFO closure, will become crucial for understanding how results from RCTs are translated into clinical practice globally. The IMPROVE (International Multicenter Patent foRamen OVale & strokE) Registry is an observational, multicenter, international registry of men and women with an ischemic stroke or TIA. The aim is to enroll 8,800 patient-years at ≥50 sites in ≥20 countries. The IMPROVE Registry will provide important information about the management and related outcomes of patients with ischemic stroke or TIA and PFO throughout different regions of the world and across a wide spectrum of healthcare systems.
Self-injurious thoughts and behaviors (SITBs), including suicide, thinking about suicide, and self-injury without intent to die, are major public health crises, with variably effective, and sometimes long and expensive, interventions. SITBs are particularly common in borderline personality disorder (BPD). Moreover, people with BPD often cannot access SITB treatment, drop out of them, and may lose their improvements after them. Reducing SITBs in BPD requires innovative interventions that have greater impact and are faster to deliver. SITBs are particularly influenced by emotion dysregulation (i.e., intense, negative emotion and difficulties changing it) and intimate relationship dysfunction, but leading evidence-based SITB interventions typically focus on the former, while neglecting the latter. For other mental health problems, couple treatments result in comparable or better individual outcomes relative to individually-delivered treatments, with added benefits of enhanced intimate relationship functioning. SITB treatment outcomes in BPD could likely be expedited and optimized with a couple intervention that targets emotion dysregulation in a relational context and intimate relationship dysfunction. This project aims to develop, refine, and test a brief SITB intervention delivered conjointly to individuals with BPD and SITBs (i.e., "patients") and their intimate partners (i.e., "partners")- Sage (formerly known as COMPASS (Connecting, Overcoming, and Moving Past Suicide and Self- injury))- that targets both emotion dysregulation and intimate relationship dysfunction to reduce SITBs and BPD symptoms in the short- and long-term. Prior to formal testing in an uncontrolled trial, it is important to solicit preliminary data regarding the clarity, accessibility, safety, tolerability, and efficacy of Sage. This project involves 3 Phases: translating Sage outlines into a manual (Phase 1); refining Sage (Phase 2); and an uncontrolled pilot trial of Sage (Phase 3). In Phase 1, the three stages of Sage will be manualized to focus on (1) developing a conjoint safety plan to reduce SITB risk, (2) reducing emotion dysregulation and intimate relationship dysfunction, and (3) changing patterns that maintain SITBs. In Phase 2, Sage will be delivered to 5-10 patients with BPD and SITBs and their partners (i.e., 5-10 couples) who will provide feedback about whether Sage is clear, helpful, and useable. This feedback will be used to refine the Sage manual. In Phase 3, the investigators will test whether Sage is safe, initially efficacious, and feasible by administering it to 15-20 patients with BPD and SITB and their partners (i.e., 15-20 couples). The investigators will examine whether Sage results in changes in SITBs and BPD symptoms in patients with BPD and SITBs, and SITB risk factors (e.g., emotion dysregulation and intimate relationship dysfunction) in both patients and partners. These outcomes will be measured multiple times per day during treatment using participant's smartphones (i.e., ecological momentary assessment), and interviews/questionnaires administered at the beginning, middle, end, and at 3 months after the intervention. The investigators predict that Sage will reduce SITBs and BPD symptoms in the patient with BPD and SITBs and improve emotion dysregulation and intimate relationship dysfunction in both patients with BPD and SITBs and their partners. This study offers a novel SITB and BPD treatment that directly targets SITBs, BPD symptoms, and the factors that drive them. Its short duration broadens the accessibility of BPD and SITB interventions with the potential to contribute to reducing SITBs and BPD symptoms on a large scale. During this period of social distancing due to COVID-19, Sage will be delivered remotely via secure videoconferencing (Zoom Healthcare). As social distancing restrictions lift, Sage will be delivered in the laboratory.
The goal of this study is to evaluate the efficacy and safety of pembrolizumab plus belzutifan plus lenvatinib or pembrolizumab/quavonlimab plus lenvatinib versus pembrolizumab plus lenvatinib as first-line treatment in participants with advanced clear cell renal cell carcinoma (ccRCC). The primary hypotheses are (1) pembrolizumab plus belzutifan plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to progression-free survival (PFS) and overall survival (OS), in advanced ccRCC participants; and (2) pembrolizumab/quavonlimab plus lenvatinib is superior to pembrolizumab plus lenvatinib with respect to PFS and OS, in advanced ccRCC participants.

This is a two-part (Phase 2/Phase 3) study of MK-5475, an inhaled soluble guanylate cyclase stimulator, in participants with pulmonary arterial hypertension (PAH). The first part (Phase 2) will assess three different doses of MK-5475 compared to placebo in a base period of 12 weeks, followed by comparison of three different doses of MK-5475 during an optional 24 month extension period. The treatment dose with the best efficacy and safety profile in the phase 2 cohort base period will be selected for use in the second part (Phase 3) of the study. The primary hypothesis of Phase 2 is that at least one MK-5475 dose is superior to placebo in reducing pulmonary vascular resistance (PVR) from baseline at week 12. The purpose of the second part (Phase 3) of the study is to confirm the efficacy, safety, and tolerability of MK-5475 at the selected dose compared to placebo during a 12 week base period followed by an extension period of up to 5 years. The primary hypothesis of Phase 3 is that MK-5475 is superior to placebo in increasing 6-minute walk distance (6MWD) from baseline at week 12.
The objective of this study is to assess the efficacy and safety of the combination of alpelisib and olaparib compared with single agent cytotoxic chemotherapy in patients with platinum resistant or refractory high-grade serous ovarian cancer, with no germline BRCA mutation detected.
The usual treatment for stuck rings includes a variety of techniques including use of ice to reduce swelling, use of lubricants, and sometimes the use of string or ring cutters. The success rate of these techniques is variable and cutting the ring is usually reserved as a last resort. Sometimes removal of a ring can take time, and can cause some small injury to the patient. Because of this, it is important to consider other methods for ring removal. This study is looking at using a device that uses compression to reduce swelling of the finger causing the ring to be stuck. This device has been approved for use in Canada. The purpose of this study is to evaluate how effective a compression device is at removing stuck rings. The study question is: how effective is a compression device at removing stuck rings? A Compression Device (CD) is a device that uses circumferential compression to reduce swelling around a stuck ring. The device is used by placing it near, but not over-top, the offending ring, and then is inflated compressing the finger. The device is applied, and the hand elevated, for approximately five minutes. The device is then removed, and with a small amount of lubricant, the ring is removed. All patients requiring ring removal at the QEII emergency department, if a compression device can be used safely, will be asked if they would like to be included in the study and have their ring removal attempted by a compression device. Following removal attempt, the clinician will document information about the ring removal. This will include some questions regarding the patient's experience with the removal. No identifying information or personal health information will be recorded. The investigators plan to collect information about use of the compression device for a period of one year. Following this time, the data will be analyzed to determine how effective the compression device is at removing rings including statements regarding patient experience. This information will be documented in a manuscript intended for publication and may be presented at academic conferences or other continuing education events. The investigators will be measuring the success rate of ring removal with the compression device. In addition, the investigators will record information on any side effects of use of the compression device, as well as patient experience including pain and satisfaction.
