Evaluation of Virtual Reality for Reducing Opioid Use After Cardiac and Thoracic Surgery
This clinical trial aims to evaluate the efficacy of virtual reality (VR) as an adjunctive therapeutic method to reduce opioid consumption during the postoperative period of cardiac and thoracic surgeries. It is a single-center, prospective, randomized trial that will include 60 patients aged 16 to 40 undergoing surgeries such as …
Methylene Blue for the Prevention of Hypotension During Hemodialysis
Hypotension is a common complication of intermittent renal replacement therapy. Methylene blue, an inhibitor of nitric oxide synthesis, has been suggested to improve hemodynamics during renal replacement therapy in ambulatory patients, but evidence is lacking for critically ill patients. This trial will assess whether methylene blue can improve hemodynamics and …
Acute Cardiovascular Responses to a Single Exercise Session in Patients With Post-COVID-19 Syndrome
The objective of the study is to compare the acute cardiorespiratory and perceptual responses to a physical exercise session in those infected by Covid-19 with and without persistent symptoms.
Effects of Transcutaneous Electrical Phrenic Nerve Stimulation and Transcutaneous Electrical Diaphragmatic Stimulation
Transcutaneous electrical phrenic nerve stimulation (TEPNS) and transcutaneous electrical diaphragm stimulation (TEDS) are modalities that use surface electrodes placed on the patients' skin to generate action potentials and contractions of the muscle fibers of the diaphragm. The primary objective will be to evaluate the efficacy of TEPNS and TEDS in …
Respiratory Mechanics Assessment at Different Head of the Bed Elevations in Mechanically Ventilated Patients
The effects of different degrees of head-of-bed elevation on respiratory mechanics are poorly explored in the literature, and no study has investigated such effects using electrical impedance tomography, esophageal and gastric balloons to identify the ideal angle for optimizing respiratory mechanics. The hypothesis is that there is a optimal degree …

This is a multicenter, single arm, open-label, extension study to evaluate the long-term safety, tolerability, and efficacy of iptacopan in participants with aHUS.
Adjuvant Chemotherapy in cfHPV-DNA Plasma Positive Patients: A Biomarker In Locally Advanced Cervical Cancer
This study hypothesizes that patients who persist with cell-free human papillomavirus deoxyribonucleic acid (cfHPV-DNA) plasma expression at the end of standard treatment, can derive the benefit of using adjuvant chemotherapy in locally advanced cervical cancer (CC). After standard treatment based on concomitant chemoradiotherapy regime, a qualitative and quantitative research of …
Use of Transcranial Magnetic Stimulation in the Post-Operative Cognitive Dysfunction in Elderly
Postoperative Cognitive Dysfunction (POCD) is a prevalent condition with significant clinical, social, and financial impacts on patients and healthcare services. The term POCD refers to any signs of new cognitive impairment that exceed the expected time for recovery from the acute effects of surgery and anesthesia. Mild Cognitive Impairment (MCI) …
