Noradrenaline Versus Standard Blood Pressure Management for Perioperative Hypotension in Non-cardiac Surgery

The effect of noradrenaline infusion versus standard blood pressure management on perioperative HYPotension in NOn-caRdiac surgery. The study aims to determine whether perioperative noradrenaline infusion is superior to standard blood pressure management for the occurrence of perioperative hypotension.

Dry Weight Reduction Intervention Via Extra Ultrafiltration

Most patients who receive hemodialysis treatments have excess fluid in their body that has slowly built up over the course of kidney disease. This extra fluid is the main cause of high blood pressure in dialysis and leads to stress on the heart and lungs.that causes debilitating symptoms and frequent hospitalizations. This trial will test whether a focused program of 4 or 8 weeks of extra ultrafiltration treatments can remove most of this extra fluid. We believe that getting rid of large amounts of extra fluid will result in sustained improvements in blood pressure and symptoms. Ultrafiltration is a gentler type of dialysis that removes fluid but does not clean the blood.

Stratified Blood Pressure Management After Endovascular Treatment for Acute Ischemic Stroke

The RESCUE-BP is a multi-centered, prospective, randomized, open label, blinded endpoint (PROBE) phase III trial. In patients with acute ischemic stroke who have undergone endovascular treatment and achieved successful recanalization, the evaluation will compare a stratified blood pressure management strategy based on the collateral circulation status with the guideline-recommended conventional blood pressure management strategy. Within each stratum, participants will be randomized in a 1:1 ratio to either the stratified blood pressure management strategy group or the guideline-recommended conventional blood pressure management group. The goal is to determine whether this can improve good functional outcomes at 90 days (90-day Modified Rankin Scale \[mRS\] score 0-2). The study consists of four visits including the day of randomization, 24±4 hours after randomization, 7±1 days after randomization and 90±7 days after randomization. Demographic information, symptoms and signs, laboratory test, neuro-imaging assessment, neurological function rating scale will be recorded during the program. The primary outcome is the modified Rankin Scale (mRS) score of 0 to 2 at 90±7 days after randomization. The primary safety outcome is the incidence of sICH within 24±4 hours after randomization.

Impact of Resistance Training Intensity on Blood Pressure

The goal of the clinical trial is to understand the effect of two resistance training protocols employing different loading intensities (% of 1 repetition maximum; 1-RM), but with standardized effort intensity (2 repetitions in reserve; RIR) on post-exercise and ambulatory blood pressure in aging females. The main questions it aims to answer are: * to examine the acute effects of low (50% 1-RM) and high (80% 1-RM) load intensity resistance exercise with a standardized high effort intensity on post-exercise hypotension and ambulatory blood pressure responses in aging females; * deepen the understanding of the mechanisms underlying acute reductions in blood pressure in response to resistance exercise performed at different load intensities. To this end, autonomic activity will be estimated alongside the measurement of central arterial compliance (i.e., carotid artery), and serum biomarkers of endothelial function; * document the affective valence and enjoyment associated with low (50% 1-RM) and high (80% 1-RM) load intensity resistance exercise when performed at a high perceived effort. Researchers will compare the effect of: 1) a low load (LL-RE) intensity protocol consisting of 3 sets of each exercise at 50% 1-RM, performed until reaching a hard perceived effort intensity (i.e., RIR-2); 2) high load (HL-RE) intensity protocol consisting of 3 sets of each exercise at 80% of 1-RM, performed until reaching a hard perceived effort intensity (i.e., RIR-2); 3) and a control condition (CON) consisting of a standardized non-fatiguing cognitive task. Participants will participate in: * A preliminary assessment visit; * Two familiarization visits to validate the exercise prescriptions; * Three experimental visits (CON, LL-RE, HL-RE).

Intraoperative Blood Pressure Management and Dexamethasone in Lung Cancer Surgery

Surgery is the front-line therapy for non-small cell lung cancer (NSCLC) but postoperative complications remains high and patients' long-term outcome is still challenging. In addition to surgery, anesthetic management particularly intraoperative blood pressure management and use of dexamethasone may affect patients' early and long-term outcomes after surgery for NSCLC. This study aims to investigate the impact of intraoperative blood pressure management and dexamethasone administration on early and long-term outcomes in patients undergoing surgery for lung cancer.
