Management of Malignant Bowel Obstruction (MBO) in Patients with Advanced Gynecological Cancers

Introduction: Second Generation Antipsychotics (SGAs) are widely used in the pediatric population. It is currently established that SGAs may induce undesirable metabolic adverse events (AEs) such as weight gain, metabolic changes in blood lipids or glucose with risk of potential cardiovascular morbidity and mortality. The Canadian Alliance for Monitoring Effectiveness and Safety of Antipsychotics in children (CAMESA) has published recommendations for monitoring the metabolic AEs of SGAs in the pediatric population. Factors that may be associated with the onset of SGA's metabolic AEs and long term consequences are less studied in the literature. The objectives of our research are to evaluate some factors that can influence the development of the SGA's metabolic AEs, and to study clinical adherence to CAMESA guidelines. Methods and analysis: The MEMAS study (Monitoring des Effets Métaboliques des Antipsychotiques de Seconde Génération) design is a multicenter, prospective, longitudinal observational study with repeated measures of metabolic monitoring up to 24 months of follow-up. Two recruiting centers have been selected for patients under 18 years of age, previously naïve of antipsychotics, starting an SGA or who have started an SGA for less than 4 weeks regardless of the diagnosis that motivated the prescription. Assessments are performed at inclusion and during follow-up for anthropometric measures (AM), blood pressure (BP) and blood tests (BT) at baseline and 1, 2, 3, 6, 9, 12 and 24 months of follow-up. Ethics and dissemination: The study protocol was approved by the Centre Hospitalier Universitaire (CHU) Sainte-Justine's Research Ethics Board (MP-21-2016-1201) in 2016 and obtained institutional suitability for the "Centre Intégré Universitaire de Santé et de Services Sociaux du Nord-de-l'Île-de-Montréal" (CIUSSS NIM) Research Center in May 2018. For all participants, written consent will be obtained from parents/caregivers as well as the participant's assent in order to enable their participation in this research project. The results of this research will be published.

This study will enroll participants with idiopathic REM sleep behavior disorder (RBD) and healthy controls for the purpose of preparing for a clinical trial of neuroprotective treatments against synucleinopathies.

This study is open to patients with a type of cancer called melanoma. Patients can join the study if their tumor cannot be removed by surgery or has spread to other organs, and are planned to receive immunotherapy as treatment for their cancer. This study is looking at whether taking calcium pantothenate supplement (a type of Vitamin B5) can increase its levels in the blood and have an effect in the immune system, when its used in combination with the immunotherapy.

Dexamethasone will be used as an adjunct to local anesthetics (bupivacaine) to prolong the duration of laparoscopically-placed transversus-abdominis plane blocks in elective colorectal resection.

The primary objective of this study is to evaluate the efficacy of tofersen in presymptomatic adult carriers of a superoxide dismutase 1 (SOD1) mutation with elevated neurofilament (NF). The secondary objectives of this study are to evaluate the safety and tolerability tofersen and to evaluate the effect of tofersen on pharmacodynamics (PD)/treatment response biomarkers when initiated prior to versus at the time of emergence of clinically manifest amyotrophic lateral sclerosis (ALS).

This screening study is intended for men and women ≥ 18 to ≤ 75 years of age who have advanced solid or hematologic malignancy. The study will assess a subject's human leukocyte antigen (HLA) subtype and tumor antigen expression profile. Based on the results, it will be determined if a subject is eligible to be considered for Adaptimmune sponsored clinical trials testing the safety and efficacy of genetically changed T cells targeting specific tumor antigens. No treatment intervention will occur as part of this screening study. Upon enrollment, subjects will be required to provide a blood sample for HLA subtype analysis. If the results of the analysis match the HLA-A subtypes noted in the inclusion criteria and do not express the HLA subtypes that are exclusionary for the available interventional clinical trial(s), then the subject will be required to provide either an archival tumor specimen or fresh tumor tissue biopsy. The tumor specimen will be screened at a central laboratory for the expression (protein or gene) of multiple antigens which may include, but are not limited to MAGE-A4. Based upon the results of these diagnostic analyses, if eligible, subjects will be referred to an appropriate available interventional clinical trial(s) at the discretion of the Investigator. Following screening, tumor samples will be retained by Adaptimmune for the purpose of developing and validating in vitro diagnostic (IVD) assay(s) for antigen expression profiling which is required for regulatory approval of a new therapeutic product indication.

Researchers are looking to further our knowledge on disease biology and treatment selection for gastroesophageal adenocarcinoma. The purpose of this study is to see how useful it is to look for changes and characteristics in your genes (molecules that contain instructions for the development and functioning of the cells) and the genes within the tumour. These characteristics may be useful in choosing treatments for patients for the future.

This study aims to develop and validate a sensitive and non-invasive eye-tracking software application. This study will obtain participant responses to brief cognitive tests designed to evaluate several key functions known to be affected by MS and non-invasive eye movement measurements in response to visually presented stimuli during specifically designed eye-tracking tests. The study data will be used to develop machine learning algorithms and validate a software application intended to track the progressive component of multiple sclerosis and associated cognitive changes.

The overarching aim of the study is to determine the role of insulin signaling on the neurobiological substrates subserving anhedonia within individuals with mood disorders (i.e., Bipolar Disorder (BD) and Major Depressive Disorder (MDD)). Specific aims include: 1. Molecular: Assessment of components of the insulin cascade, as well as of anhedonia and reward-related processes, using a proteomics and gene expression approach; 2. Physiology: Measurement of peripheral sensitivity to insulin and metabolic correlates, including body mass index and dyslipidemia; 3. Neural Circuits: Evaluation of the insulin sensitivity of prefrontal (e.g. prefrontal cortex) and striatal (e.g. nucleus accumbens, ventral tegmental area) networks in the resting-state and during an effort-based decision making test, using acutely administered intranasal insulin and functional magnetic resonance imaging (fMRI); 4. Behavioral: Measurement of willingness to make effort for rewards, as well as of other components of reward response and anhedonia, using validated behavioral tasks and clinical scales (e.g. Snaith-Hamilton Pleasure Scale - SHPS). This initiative represents a proof-of-concept study that insulin is important to anhedonia, neurocognitive functioning, and behavioural deficits in MDD, representing a novel and safe therapeutic avenue.
