High bleeding risk (HBR) patients, comprising up to 50% of those presenting with acute coronary syndrome (ACS), are a high-risk group that is increasing in size due to an aging population. The optimal selection of the potency and duration of antiplatelet therapy to reduce the risk of recurrent ischemic and bleeding events in HBR patients is still a matter of debate. Multiple strategies to reduce bleeding during secondary prevention, such as reducing the duration of dual antiplatelet therapy, using single antiplatelet therapy with a P2Y12 inhibitor, or de-escalating to a lower potency or lower-dose P2Y12 inhibitor, have been proposed. De-escalation to a lower potency or lower-dose P2Y12 inhibitor is particularly attractive because it maintains efficient pharmacological inhibition of multiple platelet pathways while potentially reducing bleeding through less aggressive activity. Yet, there has been no study comparing the effects of different de-escalation strategies with the standard potent P2Y12 inhibitors in HBR patients. The aim of the DESC-HBR study is to assess the impact of de-escalating P2Y12 inhibitor to clopidogrel 75mg, prasugrel 5mg or ticagrelor 60mg bid in HBR patients, in comparison with full-dose potent P2Y12 inhibitors, on the proportion of patients with optimal platelet reactivity (OPR). Secondary objectives involve exploring the effect of de-escalation on clinical events and patients' quality of life.

Study to evaluate the safety and tolerability of intravenous ICVB-1042

The purpose of this study is to investigate the effectiveness of a programme based on inspiratory and expiratory muscle training to improve respiratory muscle strength, functional capacity and avoid pulmonary complications in adults with cervical or high dorsal spinal cord injury (C5-D5) in acute phase.

This is a Phase 1 study investigating the safety and efficacy of Danvatirsen as a monotherapy followed by combination with Venetoclax in patients with relapsed/refractory myelodysplastic syndromes (MDS) or acute myeloid leukemia (AML). [(FDA OOPD)]

The purpose of this study is twofold: 1) Develop norms for measures of inner ear function and psychological health, and 2) Examine the feasibility of using the MINDGAPS system (a remote monitoring system) to track progress during physical therapy or rehabilitation for inner ear problems following a concussion or mild Traumatic Brain Injury.

Pulmonary vein isolation (PVI) is very effective for rhythm control in patients with paroxysmal atrial fibrillation (AF), but less successful in patients with persistent AF. Adding posterior wall ablation (PWA) to PVI is among the most promising ablation strategies to improve arrhythmiafree outcome in patients with persistent AF. Patients with left atrial posterior wall scar may benefit most from adding PWA to PVI. With previous ablation technology, posterior wall isolation (PWI) was difficult to achieve and increased the risk of procedural complications. With pulsed-field ablation (PFA), a technology is now available which is both very effective and safe for complete ablation of the posterior wall. The aim of this trial therefore is to compare the efficacy and procedural safety of two ablation strategies for the treatment of persistent AF using PFA: PVI only versus PVI with added PWA. The endpoint of atrial arrhythmia recurrence within 12 months will be assessed by an implantable cardiac monitor (ICM) with remote monitoring capabilities.

Mental illness is often chronic, severe, and difficult to treat. Though there has been significant progress towards establishing effective and efficient interventions for psychological health problems, many individuals do not gain lasting benefits from these treatments. The Memory Support Intervention (MSI) was developed utilizing existing findings from the cognitive science literature to improve treatment outcomes. In this study, the investigators aim to conduct an open trial that includes individuals 50 years and older to assess if a novel version of the Memory Support Intervention improves sleep and circadian functioning, reduces functional impairment, and improves patient memory for treatment.

The language outcome of children receiving cochlear implantation to address bilateral sensorineural hearing loss is more variable than that of typical hearing children. The research is focused upon development of neural predictive models based upon brain imaging to forecast language after cochlear implantation on the individual child level. The long-term goal is improving children's language by using predictive models to enable a custom "predict to prescribe" approach to intervene with more effective behavioral therapy for children at risk to develop poorer language. The investigators previously developed models for short term language outcome of English-learning implanted children. The aims of this study are to 1. Develop models able to predict long term outcome for English- learning and Spanish-learning children; and 2. To evaluate whether English-learning children predicted to achieve lower language based on the investigators' previously constructed models can demonstrate significant gains from Parent Implemented Communication Treatment (PICT). PICT is an intensive parent education program about strategies to improve children's communication.

Aim of the study: To investigate changes in the levels of Interleukin 34 (IL-34) in the Gingival crevicular fluid(GCF) of patients with stage II periodontitis patients before and after nonsurgical periodontal therapy and compare it with healthy individuals To correlate changes in Gingival crevicular fluid level of Interleukin 34 with changes in periodontal parameters after nonsurgical periodontal therapy

Parkinson's disease (PD) is a chronic neurodegenerative disease clinically characterized by bradykinesia, hypokinesia, rigidity, resting tremor, and postural instability. These motor manifestations are attributed to the degeneration and selective loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc), leading to a dopamine (DA) deficiency in the striatum. The environmental factors are the most common risk factor for Parkinson's disease, while hereditary determinants have minor role for disease. Furthermore, the clinical diagnosis of PD rests on the identification of characteristics related to dopamine deficiency. However, nondopaminergic and nonmotor symptoms, including cognitive dysfunction and depression, which is one of the most common and persistent symptoms, are sometimes present at an earlier disease stage and, almost inevitably, emerge with the disease progression. Neuroinflammation is considered one of the most important factors contributing critically to pathophysiology of PD . Recently, high mobility group box-1 (HMGB1) protein has been encoded as a potential inflammatory biomarker in PD. HMGB1 mediates immune response mostly through endothelial cells and macrophage activation via targeting two vital cell receptors; Toll-like receptor 4 (TLR4) and advanced glycation end products (RAGE). HMGB1 leads to a sequential cascade of inflammatory response through enhanced release of tumor necrosis factor-alpha (TNF-α) and interleukins (ILs), prominently IL-1β and IL-6. HMGB1 mediated also up-regulation of nuclear factor kappa-β (NF-κB) with subsequent flared pro-inflammatory storm.
