Early Doppler-Assisted Mobilization in Adults After Acute Ischemic Stroke

Post-stroke mobilization remains a subject of ongoing debate. While early mobilization-particularly the first out-of-bed mobilization-has been associated with reduced systemic complications and earlier rehabilitation, it also carries potential risks, such as neurological deterioration in the presence of hemodynamic instability. In this study, the primary aim is to investigate whether early mobilization, guided by hemodynamic evaluation after acute ischemic stroke offers superior outcomes compared to standard clinical care.

Effect of a Structured Physical Exercise Program on Arteriovenous Fistula Maturation for Hemodialysis in Chronic Kidney Disease Patients

For patients living with Chronic Kidney Disease who are preparing to start hemodialysis, having a well-functioning arteriovenous fistula (AVF) is essential. Although the AVF is considered the best type of vascular access, its maturation process does not always go as expected-studies show that in 28% to 53% of cases, the fistula does not mature properly, making effective dialysis more difficult. There is growing interest in using physical exercise as a way to support AVF maturation. International guidelines even recommend arm exercises for this purpose. However, there is still no clear agreement on what type of exercise, how often, or how intense it should be. This study aims to evaluate whether a structured exercise program focused on the AVF arm can help improve the fistula's development and overall function.

Immunomodulation During Pregnancy

The goal of this observational study is to learn about the effects of low dose aspirin in immunity Pregnant women taking aspirin for other reasons (preeclampsia prevention) will be studied. The main question it aims to answer is: evaluate the effect of LDA on the modulation of innate immunity cells (NK cells, monocytes, γδ T cells) and/or acquired immunity (B and T lymphocytes, Treg cells, Th cells). Participants already taking intervention A as part of their regular medical care for RA will answer online survey questions about their joint pain for 5 years.

Remote Monitoring To Identify Worsening Heart Failure The REMOTI-HF Randomized Clinical Trial

Heart failure, characterized by high mortality and morbidity rates, frequent hospital admissions, and prolonged stays in cardiology wards, significantly impacts patients' quality of life. The REMOTI-HF is a single-center randomized controlled trial designed to assess the impact of remote monitoring, utilizing the HeartLogic and TriageHF algorithms, in patients with heart failure with implantable cardioverter defibrillator or cardiac resynchronization therapy. The primary endpoints include mortality, hospital admissions related to heart failure, and visits for worsening heart failure. Moreover, we will explore the full capabilities of these algorithms, by analysing the association of physical activity, measured by the devices, with the same key outcomes. Additionally, the research will explore the relationship between the absolute values provided by the algorithms and NT-proBNP values.
