Sensorimotor Block Dynamics and Hemidiaphragmatic Palsy: Selective Trunk Block vs Supraclavicular Brachial Plexus Block
Ultrasound guided supraclavicular brachial plexus block (BPB) has been extensively studied and recommended as a sole anesthetic for upper extremity surgeries. The efficacy of ultrasound-guided (USG) SeTB for surgical anesthesia of the entire upper extremity and cadaver anatomic study evaluating the spread of the injectate after a simulated SeTB is …
Application of 3D MR Neurogram for Intraparotid Facial Nerves Evaluation
Parotid neoplasm consists of a wide range of benign and malignant lesions, and parotidectomy has been the mainstay for management of these neoplasms. Within the parotid gland there are branches of the intra-parotid facial nerves, which are tiny in calibre and are prone to injury to injury during operation. It …
Modelling Tau Distribution From DTI With Generative Adversarial Network for Alzheimer's Disease Diagnosis
The most significant impact of this project is to propose for the first time a novel generative adversarial network (GAN), as one kind of deep learning architecture, to automatically generate synthetic PET images reflecting tau deposition, from brain DTI images. If successful, this framework will become the most state-of-the-art approach …
Quantitative T1rho Magnetic Resonance Imaging in Healthy Subjects
T1rho imaging is a new MRI technique that has strong potential in neuroimaging. This technique does not require exogenous contrast agents and has high spatial resolution. In this study we aim to characterise the normal appearance of T1rho in the brain parenchyma in healthy participants. T1rho values will be measured …
A Prospective Study of Factors Related to Exacerbation and Mortality of Non-cystic Fibrosis Bronchiectasis in Hong Kong
Bronchiectasis is associated with repeated exacerbations which occurs at rates of 1.5-6.5 per patients per year, and are associated with an increased risk of admission and readmission to hospital, and high health care costs. In a local study carried out more than 10 years ago, idiopathic disease dominates and patients …
GLP-1 Receptor Agonist for Reduction of Myocardial Injury After Non-cardiac Surgery
This is an investigator initiated, multi-center, open-labelled, superiority randomized controlled trial of 372 patients undergoing elective non-cardiac surgery. Recruited patients will be randomized in a 2:1 ratio to receive single subcutaneous dose of Glucagon-like Peptide-1 Receptor Agonist (GLP-1 RAs) 1 to 14 days prior to surgery or receive routine care. …
Cross-validating the iTBS-induced Hemodynamic Response From fNIRS and fMRI: a Concurrent iTBS-fMRI-fNIRS Study
Intermittent theta-burst stimulation (iTBS) targeting the left dorsolateral prefrontal cortex (DLPFC) is well established in treating patients with major depressive disorder (MDD). However, the iTBS-induced hemodynamic response during or immediately after a full session of stimulation has not been fully investigated. Although several concurrent iTBS/functional Near Infrared Spectroscopy (fNIRS) and …
Ambulatory Flexible URS for UTUC Surveillance
This is a a prospective single-arm pilot study to investigate the safety and feasibility of flexible ureteroscopy under local anaesthesia. All consecutive patients who have undergone kidney-sparing surgery for managing upper tract urothelial carcinoma will be screened for study eligibility. The primary outcome is the procedural technical success rate. Secondary …
Faricimab Quarterly Maintenance for Neovascular Age Related Macular Degeneration
We aimed to investigate the success rate of a planned quarterly (every 12-16 weeks) faricimab injection schedule, following a disease inactivity achieved after initial 2-4 loading doses of faricimab, for nAMD to achieve stability without recurrence at a tertiary eye centre.
A Clinical and Imaging Registry of Transcatheter Aortic Valve Implantation Using JenaValve System/ J-Valve System for Patients With Pure Aortic Regurgitation
Aortic regurgitation (AR) is not uncommon. Transcatheter aortic valve implantation (TAVI) for treating pure aortic regurgitation is a potential future treatment option for pure AR especially in patients having high risk for open heart surgery. TAVI using dedicated device for pure AR has a different anchor mechanism to TAVI for …
