Recruitment

Male and female patients Undergoing laparoscopic bariatric surgeries will be subjected for lung recruitment at end of surgery before emergence from anesthesia by two different methods . to evaluate which might be safer and more effective

This platform trial aims to evaluate the effectiveness of different messaging strategies within a MyChart messaging program for research recruitment. MyChart is a patient portal system within the Electronic Medical Record (EMR), and messages can be sent directly to patients about research opportunities.

This study is a prospective, single-center, single-blind, randomized controlled clinical trial. Patients scheduled for laparoscopic bariatric surgery will be selected and randomly assigned to either the EIT-guided individualized PEEP group (Group P-eit) or the control group (Group P-8). Group P will be ventilated using the PEEP value determined by EIT, while Group C will be ventilated with a fixed PEEP value of 8 cmH2O.The primary outcome is the incidence of postoperative pulmonary complications (PPCs) within 72 hours after surgery.

Patients with obstructive sleep apnea syndrome are at higher risk for respiratory complications after surgery. Oxygen depletion and respiratory distress are common in patients with obstructive sleep apnea syndrome. In this study, the effectiveness of the recruitment maneuver applied in the postoperative period will be investigated via lung ultrasound. Recruitment is a technique performed to improve the oxygen levels of patients. Patients diagnosed with obstructive sleep apnea syndrome between the ages of 18-65 will be included in the study and anesthesia and surgical procedures will be followed. The aim of the study is to compare the pulmonary complication rates between patients who underwent recruitment and those who did not, and to examine the effects of factors such as age and gender on these complications via lung ultrasound.

There is a need to identify strategies that improve the conduct of clinical trials involving family members of intensive care unit (ICU) patients. The purpose of the present study is to evaluate recruitment and retention strategies for clinical trials involving family members of ICU patients. 4 strategies (2 recruitment and 2 retention) will be tested. Investigators will integrate the strategies into three existing studies that involve family members of ICU patients. Participants will be randomized using a 2x2 factorial design. The co-primary outcomes are recruitment percentage (participants enrolled/participants approached) and retention percentage (participants completing follow-up/participants enrolled).

This single-center observational study aims to assess the effects of continuous high-frequency oscillation (CHFO) and continuous positive expiratory pressure (CPEP) therapy on lung recruitment using electrical impedance tomography (EIT) in spontaneously breathing patients admitted to the intensive care unit.

During a vaccine clinical trial of Cytomegalovirus (CMV) vaccine, one of the participants' motivations was to prevent an infection responsible for malformations in a future child. Would their attitude towards a vaccine trial be the same in the context of a vaccine designed to protect them individually? By improving the knowledge of clinical research and determinants in women aged 18 to 40, this study could improve recruitment methods in this specific population for future vaccine trials within the CIC1408 infectious diseases and vaccinology area at Saint-Etienne University Hospital.
