AI Article Synopsis
- This study aims to compare the effectiveness of electrical impedance tomography (EIT)-guided PEEP titration versus the ARDS network's low PEEP/FiO strategy in reducing mortality and improving outcomes in ARDS patients.
- The trial includes a multicenter, randomized setup in China, with patients divided into two groups: one receiving EIT-guided PEEP and the other following a standard low PEEP protocol.
- The primary focus is on 28-day survival, with results to be analyzed using established statistical methods and published in peer-reviewed journals.
Article Abstract
Introduction: Previous studies suggested that electrical impedance tomography (EIT) has the potential to guide positive end-expiratory pressure (PEEP) titration via quantifying the alveolar collapse and overdistension. The aim of this trial is to compare the effect of EIT-guided PEEP and acute respiratory distress syndrome (ARDS) network low PEEP/fraction of inspired oxygen (FiO) table strategy on mortality and other clinical outcomes in patients with ARDS.
Methods: This is a parallel, two-arm, multicentre, randomised, controlled trial, conducted in China. All patients with ARDS under mechanical ventilation admitted to the intensive care unit will be screened for eligibility. The enrolled patients are stratified by the aetiology (pulmonary/extrapulmonary) and partial pressure of arterial oxygen/FiO (≥150 mm Hg or <150 mm Hg) and randomised into the intervention group or the control group. The intervention group will receive recruitment manoeuvre and EIT-guided PEEP titration. The EIT-guided PEEP will be set for at least 12 hours after titration. The control group will not receive recruitment manoeuvre routinely and the PEEP will be set according to the lower PEEP/FiO table proposed by the ARDS Network. The primary outcome is 28-day survival.
Analysis: Qualitative data will be analysed using the χ test or Fisher's exact test, quantitative data will be analysed using independent samples t-test or Mann-Whitney U test. Kaplan-Meier analysis with log-rank test will be used to evaluate the 28-day survival rate between two groups. All outcomes will be analysed based on the intention-to-treat principle.
Ethics And Dissemination: The trial is approved by the Institutional Research and Ethics Committee of the Peking Union Medical College Hospital. Data will be published in peer-reviewed journals.
Trial Registration Number: NCT05307913.

Background: The potential of telehealth psychotherapy (ie, the online delivery of treatment via a video web-based platform) is gaining increased attention. However, there is skepticism about its acceptance, safety, and efficacy for patients with high emotional and behavioral dysregulation.
Objective: This study aims to provide initial effect size estimates of symptom change from pre- to post treatment, and the acceptance and safety of telehealth dialectical behavior therapy (DBT) for individuals diagnosed with borderline personality disorder (BPD).

Background: Traditional nursing care often fails to meet the complex needs of hypertensive cerebral hemorrhage patients. Limited evidence exists on the efficacy of structured nursing frameworks such as the Omaha System in postoperative care for these patients.
Objective: This study aims to evaluate the efficacy of Omaha-based extended nursing care in improving patients' outcomes.

Purpose: Early interdisciplinary supportive care (ESC), including psychological interventions, can improve the survival of patients with metastatic esophagogastric cancer (EGC). The purpose of the study was to evaluate the association between psychological factors and survival in patients with metastatic EGC.
Methods: A secondary analysis was conducted for an open-label randomized controlled trial of ESC, in which 246 patients with EGC completed a distress measure (the distress thermometer) and a depression symptom measure (the Patient Health Questionnaire-9 [PHQ-9]) at baseline before cancer treatments.
