Going from an idea to an international clinical-trial and beyond: near-infrared diffuse optics to evaluate microvascular health in COVID-19 patients
Turgut Durduran, On behalf of HEMOCOVID-19 & VASCOVID consortia
ICFO-The Institute of Photonic Sciences, Spain
Endothelial dysfunction (ED) plays an important role in COVID-19 but ED cannot be evaluated at the intensive care unit (ICU). HEMOCOVID-19 (13 partners, 6 countries) consortium developed a protocol using near-infrarede spectroscopy and vascular-occlusion-test to evaluate ED. I will present the first batch of results demonstrating that ED is present in COVID-19 patients and is associated with the disease severity. I will then put this in the context of a new Horizon 2020 project, VASCOVID, where a dedicated, advanced platform is being built to ensure the clinical translation of these methods.
Two-Photon Microscopy offers high-resolution, low photobleaching and deep tissue penetration for intravital Imaging. Although inherently a non-linear 3D Imaging technique, beam scanners typically limit the acquisition speeds to allow only 2D imaging for dynamic scenes. Here I present SLIDE, a new technique for high speed Two-Photon Microscopy at >1000 frames/s, employing spectro-temporal scanning for up to MHz inertia-free line-scan rates. This allows in vivo 3D imaging at typical 2D imaging speeds (video-rate 3D imaging) or high-throughput Imaging flow cytometry of cells suspended in whole blood at >1000 cells/s.

We demonstrate the use of a compact mobile microscope for fast/instant pathology during intra-operative procedures. By using harmonic-signals generated by femtosecond near-IR pulses, pathology quality microscope images are obtained without any preparation of biopsy samples.

Micro-endoscopes based on multimode fibers (MMF) have shown great potential for minimally invasive imaging deep within tissue . Here, we show excitation polarization resolved second harmonic generation imaging (SHGIM) through a MMF. This permits the label-free identification of non-centrosymmetric structural proteins, e.g. myosin and collagen, and imaging is demonstrated in mouse tail tendon and cardiac tissue.
