More details:

The Apel-COVID project aims to establish links between SARS; inflammation & pulmonary hyperpermeability; and the apelinergic system (which is involved in cardiopulmonary homeostasis).
The biological elements will be compared and analyzed in their `phenodynamics` and their possible links with the clinical, ventilatory and organ functional data, and the outcome of the condition.
Principal investigator: Dr Olivier Lesur

GXT - GeneXpert or chest x-ray or tuberculin skin test for home contact assessment: a cluster randomized trial. The objectives of the GXT study are to compare the results resulting from three different strategies for the management of HIV-uninfected people aged 5 to 50 years who are HH contacts of microbiologically confirmed and newly diagnosed active pulmonary TB.
The study plans to recruit nearly 1,500 participants from Benin and Brazil and will start in 2020.

It has been estimated that approximately one quarter of the entire world’s population carry latent tuberculosis infection (LTBI). Of these, approximately 10% will develop disease, meaning that about 200 million persons will develop active disease out of the current vast pool with latent infection.
The primary objective of the study is to Compare completion of three different regimens of daily self-administered oral Rifampin.

The IT application developed by the LTB allows users from 6 centers in Canada, Indonesia and Vietnam to collect information through a secure web portal, about adults and children aged 10 and over, who will be randomized to one of the three study arms. The study will start at the end of 2019 and provides for a 2-year follow-up.

The LongVentKids Study is an international point prevalence study conducted in the Pediatric Intensive Care Unit (PICU). The purpose of the LongventKids study is to reveal and describe the prevalence of demographic background and care provided to patients with prolonged mechanical ventilation (PMV) in PICUs. The study involves 269 centers in 42 countries and measures several data on patients included. Patients are 18 years of age or younger and are under mechanical ventilation for more than 6 hours per day, based on invasive ventilation and NIV, on the day of the study.

CAPP is a pilot project that aims to better understand how the pessary works in the prevention of prematurity. It will inform public authorities in decision-making on the use of pessary for the purpose of prolonging pregnancy and improving the health of newborns.

Col-debout is a project of Dr. Jean-Charles Pasquier, obstetrician-gynecologist at the CHUS, which aims to detect the risk of prematurity by measuring the angle of the cervix upright. Col-debout brings together centers in Canada and Europe such as the Sherbrooke CHUS, the Laval University Hospital, the Montreal Jewish General Hospital and the University Hospitals of Geneva (Switzerland) and Toulouse (France).

RESP is a database containing information on adult patients with asthma or COPD, treated in the pneumology clinics of the HSCM and CHUS. To be included and invited to be part of the database, patients must be 18 years of age or older and have a diagnosis of asthma or COPD confirmed by an HSCM or CHUS respirologist. RESP is a project under the supervision of Dr. Lucie Blais of the HSCM.

The main objective of the ARIA research project is to build a clinical database of adults suffering from severe asthma treated at the CIUSSS external respiratory clinic of Estrie-CHUS. The project is led by Dr. Pierre Larivée, pulmologist and professor at the Faculty of Medicine and Health Sciences of the Université de Sherbrooke.

The RSR Biobank uses a computer application called BTRSR. This allows the pooling of samples while maintaining the uniqueness of each participating center. This method of operation proposes a virtual bank composed of the information related to the samples which are pooled on a central server while the samples are kept in each of the centers. This allows researchers to benefit from the full reach of a network of banks operating in common according to established criteria and to increase the possibility of obtaining fewer samples in certain fields of research thanks to the participation of several centers.

The main objective of PARDIE is to better understand the implications of the new definition of pediatric ARDS from the new Pediatric Acute Pulmonary Trauma Conference (PALICC) on the incidence and epidemiology of pediatric ARDS. PARDIE has 169 centers in the United States, Canada and the rest of the world.

INOX. Chronic obstructive pulmonary disease (COPD) is a major health problem in Canada. Among Canadians aged 55 and over, the prevalence rate is about 6%. Approximately 750,000 Canadians suffer from the disease. COPD is the fourth leading cause of death for men aged 65 years and over and seventh for women aged 65 and over. Continuous oxygen therapy is one of the few components of COPD management that improves survival. The clinical benefits of nocturnal oxygen therapy have not yet been confirmed. The study "International Nocturnal Oxygen" (INOX) will try to answer this question.

CanCOLD is a prospective, multi-center, cohort study conducted across Canada dedicated to understanding and managing Chronic Obstructive Pulmonary Disease (COPD) to reduce its impact. This cohort, which will track a population of COPD patients over time, is the first of its kind in Canada and is expected to end in 2023. The LTB participates in the CanCOLD study by creating the computer application that will support the collection of information.

PICFlu is a multicenter study on the genetic epidemiology of patients with Influenza in pediatric intensive care units of the PALISI network. Influenza A and B viruses are responsible each year for the deaths of hundreds of thousands of people around the world and cause billions of dollars in costs. Elderly people, children, and some people with special health conditions such as asthma or immune deficiency, are at high risk of a complication due to the Influenza virus.

Pangea is an international prospective study of point prevalence with follow-up of findings to investigate the epidemiology of critical acute neurological disease in children. It involves more than 84 centers in 14 countries.
