Adapting a Brief Suicide Intervention for Pediatric Primary Care: Enhancing Uptake and Impact

Suicide Prevention

Suicide is a leading cause of death among adolescents in the United States and improving access to high quality just-in-time suicide interventions to reduce risk has important public health implications. Integrating such interventions into routinely accessed settings, such as pediatric primary care, holds promise; however, many clinicians in these settings fail to adequately screen or intervene in youth suicidal thoughts and behaviors, representing a key barrier to reducing suicide. The proposed study is a pre-post quasi-experimental pilot feasibility and preliminary efficacy trial of a suicide prevention intervention informed by evidence based interventions including the SAFETY-Acute suicide prevention intervention implemented in 3 pediatric primary care clinics.

Effect of Descemet Membrane Polishing in Fuchs Endothelial Corneal Dystrophy

Fuchs Endothelial Corneal Dystrophy

Fuchs endothelial corneal dystrophy (FECD) is the leading indication for corneal transplantation worldwide. It is characterized by the accumulation of guttae and progressive loss of corneal endothelial cells, leading to corneal edema and visual impairment. Endothelial keratoplasty remains the standard treatment; however, graft shortages have driven the development of cell-based therapies involving the injection of cultured endothelial cells. A key unresolved issue is whether removal of the pathological endothelium prior to injection improves cell adhesion. Clinical data are limited and sometimes contradictory, particularly regarding endothelial polishing. The actual effectiveness of this procedure in removing guttae and enhancing the survival of injected cells remains uncertain. Therefore, an in vivo clinical evaluation is required to assess its impact on guttae removal.

Video Versus Direct Laryngoscopy for Tracheal Intubation in Pediatric Surgery

Tracheal Intubation Videolaryngoscopy General Anesthesia Difficult Airway Intubation

Tracheal intubation in paediatric patients is a high-risk procedure in which failure to achieve successful intubation on the first attempt is associated with an increased risk of complications, including hypoxaemia and airway trauma. Videolaryngoscopes have been increasingly adopted in clinical practice because they improve glottic visualisation; however, evidence of their benefit in paediatric patients remains inconsistent. The VIDEOKIDS trial is a large, pragmatic, international, multicentre, randomised controlled trial designed to compare videolaryngoscopy with direct laryngoscopy as the initial technique for tracheal intubation in paediatric patients undergoing surgery under general anaesthesia. The primary objective is to determine whether videolaryngoscopy increases the rate of successful intubation on the first attempt compared with direct laryngoscopy.

Iparomlimab and Tuvonralimab Plus Chemotherapy Before Surgery for Stage III Lung Cancer

Carcinoma, Non-Small-Cell Lung (NSCLC) Neoplasm Staging Lymphatic Metastasis

Background: For patients with resectable stage III-N2b non-small cell lung cancer (NSCLC), optimal perioperative treatment strategies remain an area of active investigation. Iparomlimab and tuvonralimab (QL1706) is a novel bifunctional antibody combination targeting PD-1 and CTLA-4, designed to enhance anti-tumor immunity. Objective: This phase II, single-arm, multicenter study aims to evaluate the efficacy and safety of neoadjuvant iparomlimab and tuvonralimab (QL1706) in combination with platinum-based chemotherapy in patients with resectable stage III-N2b NSCLC. Study Design and Methods: A total of 28 patients will be enrolled across approximately 4 centers in China. Eligible patients (aged ≥18 years, ECOG PS 0-1) with histologically or cytologically confirmed, resectable stage III-N2b NSCLC (AJCC 9th edition) will receive three cycles of neoadjuvant therapy every three weeks. Patients with non-squamous carcinoma will receive iparomlimab and tuvonralimab (5 mg/kg) plus pemetrexed (500 mg/m²) and carboplatin (AUC 5). Patients with squamous carcinoma will receive iparomlimab and tuvonralimab (5 mg/kg) plus nab-paclitaxel (260 mg/m²) and carboplatin (AUC 5). Surgical resection will be performed within 6 weeks following completion of neoadjuvant therapy. Subsequent adjuvant treatment is at the discretion of the investigator. Key Eligibility Criteria: Key inclusion criteria include pathologically confirmed T\any\N2b disease with mediastinal nodal status confirmed by EBUS/EUS or mediastinoscopy, and the determination by multidisciplinary team (MDT) assessment that the tumor is completely resectable (R0). Key exclusion criteria include known EGFR or ALK positive mutations, prior anti-cancer therapy for current lung cancer, active autoimmune disease, or uncontrolled hepatitis B or C. Study Endpoints: The primary endpoint is the pathological complete response (pCR) rate. Secondary endpoints include major pathological response (MPR) rate, objective response rate (ORR), R0 resection rate, event-free survival (EFS), overall survival (OS), impact on surgical outcomes, and safety. Exploratory endpoints involve biomarker analysis including ctDNA. Sample Size Rationale: Assuming a null hypothesis pCR rate (P0) of 8.8% (based on historical data) and an expected pCR rate (P1) of 28%, with a two-sided α of 5% and 80% power, 24 patients are required. Factoring in a 15% inoperable rate, the total sample size is 28 patients. Statistical Analysis: The primary endpoint, pCR rate, and other binary endpoints will be summarized with frequencies, percentages, and their 95% confidence intervals calculated using the Clopper-Pearson method. Time-to-event endpoints (EFS, OS) will be analyzed using the Kaplan-Meier method. Safety data will be summarized descriptively. Clinical Trial Information: This study is sponsored by The Second Affiliated Hospital of Air Force Medical University, PLA. The Principal Investigator is Dr. Yan Xiaolong.

Efficacy and Safety of CDED With Anti-TNF-α Biologics in Crohn's Disease

Crohn Disease

Crohn's disease (CD) is a chronic inflammatory bowel disease with high recurrence and surgical rates. Mucosal healing is a key therapeutic goal, yet current anti-TNF-α biologics achieve only about 30% mucosal healing. Dietary intervention, particularly the Crohn's Disease Exclusion Diet (CDED), shows promise in CD management. Preliminary data suggest that combining CDED with anti-TNF-α biologics may significantly improve mucosal healing rates (42.9% vs 25%). This single-center, prospective, randomized, controlled trial will enroll 185 adult CD patients with active disease (SES-CD ≥3), randomly assigned 1:1 to receive either anti-TNF-α biologics plus CDED or anti-TNF-α biologics alone. The primary endpoint is mucosal healing rate at week 14 (SES-CD=0). Secondary endpoints include clinical remission, endoscopic response, transmural healing, and adverse events. This study aims to provide high-quality evidence for the efficacy and safety of this combined approach in Chinese CD patients.

An International Federated Model for Wearable-derived Remote Longitudinal Motor Monitoring in Young Children With Spinal Muscular Atrophy Compared With Healthy Controls: Active-NBS Study (UK)

Spinal Muscular Atrophy (SMA)

Active-NBS is a study to evaluate the muscle development of patients with spinal muscular atrophy (SMA) who are diagnosed at birth. Medicines have become available in the last decade, and many patients are treated very early. Treatments are most effective if used before the patient develops symptoms. However, some patients may show symptoms by the time they receive treatment. This means that even with early diagnosis, they might still develop muscle weakness despite treatment. The investigators want to see when the movements of patients diagnosed at birth differ from normal development. This information will help identify the best time to give additional medicines currently being developed to support the muscle. The investigators will track the progress of up to 60 patients over a maximum of 30 months using wearable technologies which are worn at home. The investigators aim to validate their outcomes for use in this age group. The wearable devices are called Syde and Motor Assessment of an Infant in a Jumpsuit (MAIJU). They will be worn at regular intervals during the study and will not involve extra hospital visits for patients. The study will also recruit up to 30 healthy control participants and follow them for up to 30 months. This will help define normal development with use of the Syde device. Active-NBS will be conducted in the UK and internationally using a federated data model. Collaborative sites will collect harmonised data in accordance with the Active-NBS protocol, with data integration and oversight managed by the University of Oxford. International sites may contact the Oxford study team to establish collaboration.
