The goal of this observational study is to learn about heart function and high lung blood pressure in patients with heart failure. The main question\[s\] it aims to answer are whether we can improve the ability to predict patients who will have complications after they receive treatment including heart transplant and left ventricular assist devices.

An investigation to find out if Newborn Infant Parasympathetic Evaluation (NIPE) index predicts postsurgical pain in children, since NIPE is thought to may be of guide to the appropriate therapy in a timely and objective manner, thereby improving patient safety, parental satisfaction, and reducing healthcare costs. We think that, validating the utility of NIPE in children under 3 years of age will allow the implementation of a novel pain assessment tool to our current practice of anesthetic care. This will improve the perioperative pain management, in particular for patients who are unable to communicate pain, with the potential to reduce detrimental consequences of postoperative pain. And also determining the relationship between the NIPE scores and validated FLACC scale for post-operative pain and PAED scale during the recovery from anesthesia and also to determine whether NIPE values at extubation correlates with the incidence of moderate and/or severe pain in PACU.

This study aims to develop and validate a test for diagnosing ovarian and endometrial cancers early. It relies on detecting somatic mutations that are associated with these cancers in a biofluids sample taken from the cervix and the uterine cavity.

A phase IIR cmRCT trial companion to PERa registry, investigating the merit of SABR consolidation in men with metastatic prostate cancer. 80 patients will be randomly selected to be offered experimental SABR based on PSMA-PET detected disease after maximal systemic response. The primary endpoint is the rate of FFS at 1 year. Patients will be stratified according to hormone sensitive vs resistant disease prior to randomisation.

The purpose of this study is to identify pharmacogenetic profiles associated with selective serotonin reuptake inhibitors (SSRI)-induced behavioral disinhibition in children with Major depressive disorder (MDD), anxiety disorders and/or obsessive-compulsive disorder (OCD) that could be used clinically to reduce the incidence of this adverse event and improve health outcomes.

Hypospadias is one of the most common congenital malformations of the genitalia in boys, and is typically managed by surgical intervention. During pediatric urological surgery, caudal anesthesia is one of the most common regional anesthetic techniques used. Also known as caudal block, it has been shown to be a safe and effective anesthetic technique in children with a low incidence of anesthesia-related complications.While the reported incidence of complications directly associated with caudal block is low, there is scarce and inconclusive evidence on the impact of caudal anesthesia on the incidence of surgical complications. As a result, the objective of this superiority, randomized controlled trial is to assess whether the use of caudal anesthesia, when compared to dorsal penile block, is associated with a higher rate of urethrocutaneous fistulas and glans dehiscence post hypospadias repair.

The study wishes to examine whether "extended" antipsychotic treatment, in this case, antipsychotic treatment every other day, is as effective as daily treatment. It is also evaluating whether there may be differences in terms of side effects. Participants will be randomly assigned to either the treatment as usual group (i.e., taking antipsychotic daily) or the extended dosing group (i.e., taking antipsychotic one day on, one day off). That means, like flipping a coin, there is a 50/50 chance that participants will continue on daily dosing of your antipsychotic or have it switched to every other day dosing. This study will last for 1 year. Participants will be evaluated at the beginning and every two weeks during the first 6 months, with visits once every 4 weeks for the final 6 months. In total, participants will make 22 visits over 52 weeks to the investigator's office. The investigators hypothesize that with ED, there will be no change in symptom severity but improvement in the frequency and severity of side effects, wellbeing, and functioning.

Patients with stroke have a 25x higher risk of cardiovascular complications within the first 30 days of the event compared to individuals without stroke. The mechanisms behind these complications are not well understood. Evidence suggests that inflammation plays a central role. With the present proof-of-concept prospective cohort study, the investigators aim to demonstrate that patients develop cardiac inflammation after stroke by performing positron emission tomography (PET) magnetic resonance imaging (MRI) of the heart within 15 days after stroke. As a secondary aim, the investigators will evaluate whether post-stroke cardiac inflammation persists at 3 months after stroke. The control group will be comprised of age- and sex-matched individuals without stroke.

This is a prospective, observational, multi-center cohort study of pediatric cardiac arrests. The purpose of the study is to determine the association between chest compression mechanics (rate, depth, flow fraction, compression release) and patient outcomes. In addition, the investigators will determine the association of post cardiac arrest care with patient outcomes.

Owing to the rarity, severity, speed of progression and fatal prognosis of infantile and juvenile GM1, there is a limited understanding of overall disease progression and meaningful outcome measures. This study aims to build a natural history data set through collection of a number of clinical, imaging, and laboratory assessments that may be specific predictors of GM1 disease progression and clinical outcome. Having a GM1 natural history data set can inform potential efficacy endpoints and biomarkers for future clinical trials. This natural history study will follow up to 40 subjects diagnosed with GM1 gangliosidosis (up to 20 infantile (Type 1) and 20 late infantile/juvenile (Type 2)) for up to 3 years. Visits will be conducted every 6 months, during which several procedures will be performed and the data recorded in order to learn about the natural course of the disease, including changes in clinical and neurological assessments and electrophysiologic, imaging and biofluid biomarkers. Study procedures include: physical \& neurological exam, blood \& urine sample collection, questionnaires \& assessments of development, seizure diary, ECHO, ECG, x-ray and ultrasound (if MRI not performed), EEG and genetic testing (if not already done). The following procedures are subject to local/institutional policies and the medical discretion of the Study Physician: MRI, lumbar puncture (spinal tap) and General anesthesia/sedation (for MRI and LP).
