Postural Tachycardia Syndrome (POTS) is a disabling disorder that typically affects women of childbearing age. The hallmark feature is that there is an excessive increase in heart rate on standing, and this is associated with numerous symptoms when upright that get better when lying down. We do not understand WHY people get POTS, but there is a suggestion that autoantibodies (AAb; antibodies within us that target our own body) may play a role. Specifically, we are interested in AAb that may target different types of adrenalin receptors. In this study, we seek to characterize the physiology of POTS with formal cardiovascular autonomic reflex testing, blood draws to characterize the POTS and to look for autoantibodies, and inflammatory markers, and then give small amounts of short-acting medications that target different adrenalin receptors to see the effect on heart rates and blood pressures. This may help us to better understand the cause of POTS in some people, and come up with better ways of treating this disorder.

The objectives of this group project is to collect synovial fluid (SF) and paired sera and carry out preclinical studies to evaluate, alone or by combination testings, the potential of novel biomarkers for their prevalence and diagnostic/prognostic values in patients with arthritis, and to determine how therapeutic intervention regulate their levels.

The working hypotheses are as follows: #1 The processing of performance signals by automated lognormal segmentation and the extraction of the parameters of interest will make it possible to distinguish groups of patients from healthy elderly subjects. #2 The three instrumental approaches will not have the same degree of reliability as a predictive biomarker of clinical diagnosis established by consensus.

By 2050, one in six people in the world will be over 65, leading to an increase in the number of people with neurocognitive disorders (NCD), such as Alzheimer's disease. The number of cases will rise from 57 million to 153 million by 2050. This presents challenges for healthcare systems, as NCDs affect not only mental health but also the physical health, psychological well-being, and social relationships of patients, as well as their caregivers (PCA). In Quebec, primary care is often inadequate for people living with NCDs due to delays in accessing resources, incomplete coverage of needs, and the COVID-19 pandemic, which has exacerbated these challenges. This situation can lead to a deterioration in patients' health, affecting their quality of life as well as that of their PCAs, while also increasing healthcare costs. Many elderly people wish to age at home, but cognitive and functional decline complicates this desire. PCAs, generally family members or close friends, play an essential role in the daily support of these individuals. Their role, as defined in the Act to support caregivers in Quebec, includes non-professional and voluntary assistance to improve the quality of life of the person being cared for. However, the support provided by PCAs can lead to significant stress, especially if public services are insufficient. The exhaustion of PCAs is often correlated with the severity of the care recipient's loss of autonomy. This exhaustion impacts the mental and physical health of PCAs, leading to isolation, depression, and anxiety, as well as reduced productivity and an increase in sick leave. It is therefore urgent to find support solutions to prevent PCA burnout. Telehealth, which involves remote consultations through information and communication technologies (ICT), appears to be a promising solution to improve access to care for people with NCDs, especially in underserved areas. By enabling remote monitoring, telehealth facilitates aging in place while stimulating the remaining capacities of patients, such as responsiveness to sensory stimuli. Artificial intelligence (AI) is also a promising tool for tracking the health of older adults in real-time, detecting early signs of diseases, and providing personalized recommendations. Virtual assistants or avatars, like "Talk-to-Jo," can interact with patients to reduce their sense of loneliness. However, the effectiveness of these technologies depends on their accessibility and adaptability to the needs of patients, particularly in cases of sensory impairments. "Talk-to-Jo" is a digital avatar designed for older adults with NCDs and their PCAs. It asks questions about memory and depression and provides tailored recommendations to prevent or stabilize detected disorders. A first version of this tool is currently available on a tablet. With the growing number of people living with NCDs, it is essential to develop support solutions based on telemedicine and AI. It is important to assess the usability and acceptability of these technologies by patients and their PCAs to ensure their effectiveness.

The goal of this randomized controlled trial is to investigate the impact of routine bladder catheterization in uncomplicated cesarean sections on hospitalization time (readiness to discharge), time to ambulation, urinary retention, development of urinary tract infections, prevention of bladder injury, operating time, and patient satisfaction.

Claustrophobia is an irrational fear of restriction and suffocation. It is a specific phobia, according to DSM 5. Claustrophobic patients may fear that restriction of their limbs will hinder their ability to move quickly towards safety. MRI may trigger claustrophobia, because this diagnostic procedure involves a patient laying in a narrow tube. Premedication before MRI scan may occasionally reduce claustrophobia. Prospective observational crossover study of claustrophobic patients who are undergoing MRI scan. At alternate MRI scan sessions, each patient receives rotational premedication using Lorazepam 1mg; or Clonidine tablet 0.2mg; or combined Clonidine 0.2mg + Lorazepam 1mg. Patient will use Claustrophobia Questionnaire, a validated tool, to collect data on the days before and after each MRI scan. CLQ is a patient-administered tool used to assess claustrophobia. In addition, patient will use General Anxiety Disorder Questionnaire, a validated tool, to collect data on the days before and after each MRI scan. GAD-7 is a patient-administered tool that is used to assess anxiety.

The purpose of this randomized controlled pilot trial is to test the effectiveness of a six-week tailored physical activity program with and without peer mentoring on the psychological constructs and exercise behaviour of inactive undergraduate women. The objectives are to: * Quantify the degree to which a peer-mentorship intervention affects exercise motivation determined through three basic psychological needs (i.e., autonomy, competence, and relatedness). * Examine general psychological distress and exercise engagement throughout the study. * Qualitatively explore participants' experiences following the completion of the program using an open-ended survey to gain a better understanding of its impact. Researchers will compare the parallel arm conditions to see how the inclusion of social support impacts exercise engagement. Participants will be asked to engage in exercise three times a week at the campus gym; those in the intervention condition will have an assigned peer-mentor who will join them for one weekly session and virtually communicate with them between sessions.

While undergoing chest wall resection, a surgeon's major concern is obtaining an appropriate surgical margin. Difficulty or failure to do so can result in prolonged operative time, need for re-operation due to a positive resection margin, or need for complex chest wall reconstruction due to unnecessarily wide resection. Over the last decades, surgical navigation systems have been developed to improve operative precision in various surgical fields. This is achieved by integrating patient images with intraoperative findings.

The Study To Understand Tilt Tests versus Extended Recordings (STUTTER, POST 10) will test the hypothesis that first performing a diagnostic HUT in older patients with syncope of unknown cause will provide earlier and more diagnoses than inserting an ICM.

This is a Phase III, randomised, open-label, sponsor-blinded, 3-arm, multicentre, global study assessing the efficacy and safety of rilvegostomig in combination with bevacizumab with or without tremelimumab compared to atezolizumab in combination with bevacizumab. This study will be conducted in participants with advanced HCC who are not amenable to curative therapy or locoregional therapy
