Perspectives on the use of decellularized/devitalized and lyophilized human perinatal tissues for bone repair: Advantages and remaining challenges.

Human amniotic membrane (hAM) has been extensively used for several decades as a bioactive scaffold for regenerative medicine. In its cryopreserved form-one of the main storage formats-the presence of viable cells has often been questioned. Furthermore, there is little published evidence of the role of endogenous amniotic cells from cryopreserved hAM in tissue repair.

Validity evidence of a new virtual reality simulator for phacoemulsification training in cataract surgery.

This study aims to assess validity evidence of the new phacoemulsification module of the HelpMeSee [HMS] virtual reality simulator. Conducted at the Ophthalmology Department of Strasbourg University Hospital and Gepromed Education Department, Strasbourg, France, this cross-sectional study divided 20 surgeons into two groups based on their experience over or under 300 cataract surgeries. Surgeons filled out a background survey covering their phacoemulsification experience and prior simulator use before undergoing single-session simulations on the EyeSi [EYS] and HMS simulators.

Retinal microvascular changes in unilateral functional amblyopia detected by oct-angiography and follow-up during treatment.

Objective: To evaluate the macular microvascular changes using optical coherence tomographic angiography (OCT-A) in children with unilateral amblyopia and their reversibility during treatment.

Methods: Patients with unilateral strabismic or anisometropic amblyopia or residual amblyopia from early congenital cataract surgery, examined between October 2019 and March 2021, were included. Vessel density and perfusion density in the superficial capillary plexus and area, perimeter and circularity of the foveal avascular zone (FAZ) were analysed using OCT-A in amblyopic eyes, contralateral eyes and control group healthy eyes.

Questions about Residual Cell Viability in Cryopreserved Human Amniotic Membrane and Its Impact on Clinical Applications.

We questioned the relevance of evaluating residual cell viability in human amniotic membrane (hAM) after its cryopreservation since cell survival is controversial and its ability to act as a matrix (including the presence of growth factors and cytokines) appears to be most important for tissue regeneration purposes. We also discussed the usefulness of osteodifferentiating amniotic cells in whole hAM for bone repair applications. We have evidence that determining residual cell viability after cryopreservation and hAM osteodifferentiation is not justified.

Predictive factors for exudation of quiescent choroidal neovessels detected by OCT angiography in the fellow eyes of eyes treated for a neovascular age-related macular degeneration.

Background: To identify predictive factors for exudation for quiescent choroidal neovessels (qCNV) in the fellow eyes of eyes treated for a neovascular age-related macular degeneration (AMD).

Methods: Prospective observational study. One hundred and forty-four contralateral eyes of 144 patients treated for wet AMD were analysed.

Assessment of the type of farmers' low back pain.

Background: Spinal overload among blue-collar workers occurs most frequently in the lumbar spine. Long-lasting spinal overload results in pain syndromes leading to limitations in everyday and professional life.
