Identification of Predictive Factors for Failure of Cholangioscopy-assisted Lithotripsy in the Management of Complex Bile Duct Stones: a Retrospective Study
This study aims to optimize the management of complex biliary stones by identifying predictive factors for SpyGlass lithotripsy failure.
VisR Ultrasound for Noninvasively Interrogating Stromal Collagen Organization in Women as a Breast Cancer Biomarker: Evaluation of Anisotropy in Cancer Patients
Purpose: This study will evaluate how measurements of tissue stiffness, viscosity, and anisotropy using non-invasive ultrasound imaging correlate with breast tumor malignancy and response to chemotherapy. Participants: Up to 200 women with benign or malignant breast tumors for arm 1 and up to 50 women undergoing neoadjuvant chemotherapy in the …
A COMPARISON OF LEFT VENTRICULAR FUNCTION IN THE APICAL 4 CHAMBER AND SUBCOSTAL 4 CHAMBER TTE VIEWS IN THE PERIOPERATIVE SETTING
This study aims to examine the correlation and agreement of regional and global measurements of ventricular function in the apical 4 chamber and subcostal 4 chamber view. Additionally, we will explore limitations of the technology and explore the effect of left lateral positioning.
The Role of Toll-like Receptor-4 in Periodontitis Patients With End-stage Renal Disease in a Sample of Egyptian Population
Chronic kidney disease (CKD) is a significant public health issue in Egypt, leading to end-stage renal disease (ESRD). ESRD patients often suffer from oral abnormalities due to the disease and medications. Periodontitis is linked to systemic diseases, including renal disease, with inflammation playing a key role. TLR4 genetic variations may …
A Translational Study to Describe Clinical Characteristics, Biomarkers and to Identify Phenotypes and Endotypes Associated With Differential Outcomes in Chinese Population
A Translational Study to Describe Asthma Patient Clinical Characteristics, Treatment Patterns, Biomarkers and to Identify Phenotypes and Endotypes associated with Differential Outcomes that may Support Future Development of Personalised Treatment Strategies in Chinese Population
A Worldwide Pregnancy Safety Study to Assess Maternal, Fetal, and Infant Outcomes Following Exposure to Efgartigimod During Pregnancy and/or Breastfeeding.
This is a multi-country, prospective safety study of pregnant women exposed to efgartigimod any time within 25 days prior to conception or any time during pregnancy. Women exposed to efgartigimod only during breastfeeding will also be eligible to enroll. Background rates of major congenital malformations (MCMs) will be obtained from …
Prognosis of Cirrhotic Patients Admitted to the General Intensive Care Unit Between 2014 and 2024: a Regional Retrospective Multicentre Cohort Study
Ten years after our team's publication, practices have changed considerably in the management of severe cirrhotic patients. This study will analyse these practices in primary care hospitals and in a tertiary centre, and assess the impact of these changes on the prognosis of these patients. The following hypotheses will be …
Accuracy of EEG Slow Wave Activity in Predicting Favourable Outcome in Patients With Hypoxic Brain Injury - A Substudy of STEPCARE Trial
This is an observational substudy embedded in the STEPCARE Trial. The study involves EEG analysis, covered by the ethics approval of STEPCARE Trial. The investigators aim to compare the accuracy of a continuously measured algorithm-based EEG index, C-Trend Index, with retrospective visual analysis of continuous EEG in predicting favorable functional …
Non-Invasive Measurements of Changes in Pulmonary Artery Pressure in Intensive Care Unit Patients Using Electrical Impedance Tomography - A Feasibility Study
To assess whether changes in electrical impedance - measured using an electrical impedance tomography (EIT) chest belt - can be used to derive changes in pulmonary artery pressure (PAP) in critically ill patients when compared to invasive gold-standard PAP measured using pulmonary artery catheter (PAC).
Negative HPV Test Results on Infinity/GeneXpert® With the Presence of a Late Amplification Signal: What Does This Mean ? (PaPCR)
The aim of this retrospective, single-center, observational study is to improve the diagnosis and interpretation of cervical cancer by better detection of epithelial lesions in the case of a late HPV PCR amplification signal rendered negative by routine laboratory testing using GeneXpert® technology. The various evaluation criteria are : Presence …
