Accurate diagnosis of corneal pathology and morphological identification of different corneal layers require clear delineation of corneal three-dimensional structures and en face or cross-sectional imaging of palisade of Vogt (POV), neovascularization (NV) or corneal nerves. Here we report a prototype of full-field optical coherence tomography (FF-OCT) system with isotropic sub-micron spatial resolution in the en face and cross-sectional views. It can also provide three-dimensional reconstructed images and a large field of view (FOV) by stitching tomograms side by side. We validated the imaging power of this prototype in in vivo rat and rabbit eyes, and quantified anatomical characteristics such as corneal layer thickness, endothelial cell density and the intensity profile of different layers. This FF-OCT delineated the ridge-like structure of POV, corneal nerve bundles, and conjunctival vessels in rat eyes. It also clearly identified the vessel walls and red blood cells in rabbit model of corneal NV. The findings provided by this FF-OCT are expected to facilitate corneal disease diagnosis and treatment.

Background: High maternal morbidity and mortality rates globally, especially in low-income and lower-middle-income countries, highlight the critical role of skilled health care providers (HCPs) in preventing pregnancy-related complications among disadvantaged populations. Lebanon, hosting over 1.5 million refugees, is no exception.

Objective: To describe the sociodemographic and clinical characteristics of individuals exposed to smoking or biomass smoke and followed at primary health care (PHC) centers across three states in Brazil.
Methods: This was a cross-sectional multicenter study including patients followed at any of four PHC centers in Brazil. Patients ≥ 35 years of age who were smokers or former smokers, or were exposed to biomass smoke were included, the exception being those with physical/mental disabilities and those who were pregnant.

Purpose: The study aimed to assess the interconnection of quality of life (QoL) variables and identify key areas for which interventions could improve QoL among men who have sex with men (MSM) living with HIV on antiretroviral therapy (ART).
Methods: A cross-sectional study was conducted in Jinan of Shandong Province, between October to December 2020. Undirected network analyses were conducted to examine and visualize the interconnections between QoL variables among MSM living with HIV.

Objective: There is a lack of research on how illness representations as represented in the Common Sense Self-Regulation Model (CS-SRM) emerge and develop. We aimed to describe the evolution of COVID-19 illness representations over time, and to explore associations with sociodemographic characteristics and protective behaviours.
Methods And Measures: This study (June 2020 release from lockdown to February 2021 after vaccine roll-out) used 17 independently recruited cross-sectional cohorts.

Background: The success of disease registry systems (DRSs) depends on developing software that aligns with the registry's specific needs.
Objective: This study focuses on localising the Checklist with Items for Patient Registry sOftware Systems (CIPROS) to facilitate the DRS assessment.
Method: This applied and cross-sectional study was carried out in 2023 in six phases.
