Cerebral Blood Flow in Neonates During Major Cardiac Surgery.
Rationale: During cardiac surgery, neonates are at high risk of cerebral damage: 36-78% will have new cerebral lesions after surgery. Adequate cerebral perfusion (CBF) is mandatory to prevent postoperative brain damage and neurobehavioral outcomes. For CBF, the systemic blood pressure should be managed above the brain's critical closing pressure (CrCP), …
Tracheal Tube and Swallowing After Head and Neck Surgery
The present study was designed as a cross-sectional observational study providing the enrollment of tracheostomized patients undergoing major oncological surgery for head-neck cancer. Aims to provide objective data on the bolus transit during swallowing in tracheostomized patients with tracheal tube and without tracheal tube closing directly the tracheal stoma with …
Glucose Homeostasis, Metabolomics and Pregnancy Outcomes After Bariatric Surgery
The aim of the GLORIA study is to determine whether an altered glucose metabolism (with more hypoglycaemia and glycaemic variability) and altered metabolomics during pregnancy after bariatric surgery contribute to the increased risk for adverse pregnancy outcomes such as small-for-gestational age infants. In addition, the investigators also aim to evaluate …
Multimodal Imaging in Vitreo-retinal Surgery and Macular Dystrophies
The aim of the study is to identify morphological and functional biomarkers of post-operative recovery after vitreoretinal surgery, using decisional support systems (DSS), based on multimodal big-data analysis by means of machine learning techniques in daily clinical practice
Impact of Sinus Surgery on Individuals With Cystic Fibrosis
This study will be a prospective, observational study of patients who undergo endoscopic sinus surgery for cystic fibrosis-related chronic rhinosinusitis (CRS). Individuals who do not undergo surgery but are treated medically for CRS will also be enrolled to serve as a control group. Outcomes analyzed will include pulmonary, quality of …
Scleroderma Registry & Repository at the Hospital for Special Surgery
The overall objective of the Scleroderma Registry is to support and promote the basic science and clinical research of this complex rheumatic disease at the Hospital for Special Surgery (HSS). The registry facilitates our understanding of the clinical features, pathobiology, genetics of Scleroderma. This will ultimately lead to a potential …
Comprehensive Computed Tomography Guidance of Coronary Bypass Graft Surgery
Apply CT angiography, CT perfusion imaging and advanced image processing techniques to improve revascularization decision-making and surgical strategies in patients undergoing coronary artery bypass graft surgery.
OSA as a Remote Ischemic Preconditioning in Vascular Surgery
Ischemia and reperfusion (I/R) injury during abdominal aortic aneurysm (AAA) repair is inevitable and may lead to postoperative multi-organ failure. Remote ischemic preconditioning (short periods of ischemia in anticipation of longer period of ischemia) may act protectively against ischemia. Studies of ischemic preconditioning in patients with AAA are conflicting. Obstructive …
The Pattern of Dry Eye Disease After Cataract Surgery
This study is designed to explore dry eye disease (DED) pattern: ocular surface, corneal morphological changes, patients' subjective assessment of DED and their correlations with ocular surface inflammation, pain biomarkers after cataract surgery according to ocular surface lubrication with artificial tears during long-term follow-up.
Intra-operative Detection of Positive Margins in Breast Surgery
In this project, we will develop a unique OCT-Raman system based on a selective sampling approach optimised for high-resolution analysis of whole lumpectomy specimens. The aim of using OCT is not to detect the cancer but to identify the adipose tissue, such that the large adipose tissue regions are excluded …
