Microdissection of Distinct Morphological Regions Within Uveal Melanomas Identifies Novel Drug Targets.

: Uveal melanomas (UMs) are rare but often deadly malignancies that urgently require viable treatment options. UMs often exhibit tumour heterogeneity, with macroscopic and microscopic differences in morphology between different regions of the same tumour. However, to date, the clinical significance of this and how it may help guide personalised therapy have not been realised.

Visual Outcomes after Spontaneous and Surgical Closure of Small Idiopathic Macular Holes: A Comparative Study.

Introduction: Small full-thickness macular holes (FTMHs) are classically treated surgically but can also occasionally close spontaneously. Long-term visual outcomes of spontaneously closed FTMHs are not well described. We compared best-corrected visual acuity (BCVA) after surgical and spontaneous closure of idiopathic FTMH (IMHs) and assessed the effect of IMH size on BCVA.

Benefit of Optical Coherence Tomography-Angiography in Patients Undergoing Transsphenoidal Pituitary Adenoma Surgery: A Prospective Controlled Study.

Background: Although visual field (VF) defects are common in compressive pituitary adenoma (CPA), their pathophysiology has not been fully elucidated. The mechanical theory (i.e.

A rationally designed antigen elicits protective antibodies against multiple nosocomial Gram-positive pathogens.

ESKAPE pathogens are responsible for complicated nosocomial infections worldwide and are often resistant to commonly used antibiotics in clinical settings. Among ESKAPE, vancomycin-resistant Enterococcus faecium (VREfm) and methicillin-resistant Staphylococcus aureus (MRSA) are two important Gram-positive pathogens for which non-antibiotic alternatives are urgently needed. We previously showed that the lipoprotein AdcA of E.

Maternal immune factors involved in the prevention or facilitation of neonatal bacterial infections.

Newborns, whether born prematurely or at term, have a fully formed but naive immune system that must adapt to the extra-uterine environment to prevent infections. Maternal immunity, transmitted through the placenta and breast milk, protects newborns against infections, primarily via immunoglobulins (IgG and IgA) and certain maternal immune cells also known as microchimeric cells. Recently, it also appeared that the maternal gut microbiota played a vital role in neonatal immune maturation via microbial compounds impacting immune development and the establishment of immune tolerance.

Gut microbiota in SLE: from animal models to clinical evidence and pharmacological perspectives.

Systemic lupus erythematosus (SLE) is a multifactorial autoimmune disease driven by complex interactions between genetics and environmental factors. SLE is characterised by breaking self-immune tolerance and autoantibody production that triggers inflammation and damage of multiple organs. Given the highly heterogeneous nature of SLE, the treatments currently used are still not satisfactory with considerable side effects, and the development of new therapies is a major health issue for better patient management.

Gut microbiota in systemic lupus erythematosus patients and lupus mouse model: a cross species comparative analysis for biomarker discovery.

An increasing number of studies have provided strong evidence that gut microbiota interact with the immune system and stimulate various mechanisms involved in the pathogenesis of auto-immune diseases such as Systemic Lupus Erythematosus (SLE). Indeed, gut microbiota could be a source of diagnostic and prognostic biomarkers but also hold the promise to discover novel therapeutic strategies. Thus far, specific SLE microbial signatures have not yet been clearly identified with alteration patterns that may vary between human and animal studies.

Human Stool Preservation Impacts Taxonomic Profiles in 16S Metagenomics Studies.

Microbiotas play critical roles in human health, yet in most cases scientists lack standardized and reproducible methods from collection and preservation of samples, as well as the choice of omic analysis, up to the data processing. To date, stool sample preservation remains a source of technological bias in metagenomic sequencing, despite newly developed storage solutions. Here, we conducted a comparative study of 10 storage methods for human stool over a 14-day period of storage at fluctuating temperatures.

OCT-angiography for the diagnosis of radiation maculopathy in patients treated with proton beam therapy: A 2-year prospective study.

Purpose: Radiation maculopathy (RM) is the leading cause of visual acuity (VA) loss after proton beam therapy (PBT) of choroidal melanoma. The aim of this study was to assess the value of optical coherence tomography-angiography (OCT-A) for the diagnosis of RM in patients with choroidal melanoma treated with PBT.

Materials & Methods: This 2-year prospective, descriptive, single-center study included patients treated with PBT for choroidal melanoma.

Biopsy for molecular risk stratification in uveal melanoma: Yields and molecular characteristics in 119 patients.

Background: Prognostic cytological and molecular features of uveal melanoma have been well researched and are essential in management. Samples can be obtained in vivo through fine needle aspirate biopsy, vitrector cutter, forceps or post-enucleation for off-site testing. This study aims to examine cytological and chromosome microarray yields of these samples.

Development of new therapeutic options for the treatment of uveal melanoma.

Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. Important cytogenetic and genetic risk factors for the development of UM include chromosome 3 monosomy, mutations in the guanine nucleotide-binding proteins GNAQ/GNA11, and loss of the BRACA1-associated protein 1 (BAP 1). Most primary UMs are treated conservatively with radiotherapy, but enucleation is necessary for large tumours.

[Orbital mantle cell lymphoma succesfully treated by Bcl-2 inhibitor: Report of a case].

Lymphoma is the most common orbital malignancy in adults. Among the types of lymphoma, mantle cell lymphoma is a particularly aggressive form, often discovered through systemic involvement, with a dismal prognosis due to frequent recurrences. It is secondary to a t (11 ; 14) (q13; q32) chromosomal translocation resulting in an anti-apoptotic signal via overexpression of Bcl-2.

[Anatomical description of the retro-caruncular approach and its application in oculoplastics: A cadaveric study].

Purpose: To describe the anatomical landmarks of the retro-caruncular approach and its clinical applications based on a cadaveric study.

Patients And Method: A dissection of 8 orbits providing from 4 fresh cadavers was carried out at the anatomical laboratory of the University Hospital of Nice, France between October 2018 and January 2019.

Results: Main anatomical relationships encountered are anteriorly the Duverney-Horner muscle and the lacrimal sac, posteriorly the anterior and posterior ethmoidal arteries, superiorly the pulley of the superior oblique muscle, inferiorly the lacrimonasal duct and the tendon of the inferior oblique muscle.
