Meibomian Gland Dysfunction and Dropout in Diabetic Patients with Non-Proliferative Diabetic Retinopathy.

This study aims to compare meibomian gland (MG) dropout and MG dysfunction (MGD) between patients with diabetes mellitus (DM) with moderate-severe non-proliferative diabetic retinopathy (NPDR) and patients with no diabetes (NDM). This prospective, transversal, age, and gender-matched case-control study included 98 DM and 106 NDM eyes. Dry eye disease (DED) and MGD evaluations were performed, including meibography (Keratograph 5M).

Proliferative vitreoretinopathy and its relationship with inflammatory serum biomarkers.

Aim: To analyze if a relationship between levels of inflammatory serum biomarkers and severity of primary proliferative vitreoretinopathy (PVR) exists.

Methods: A retrospective case-control study. The healthy adult patients with rhegmatogenous retinal detachment and primary PVR were included in the PVR group.

Corneal and Ocular Surface Contributions From Mexico: A Bibliometric Analysis From 1913 to 2022.

Objective: This study aimed to investigate all recorded corneal and ocular surface research by Mexican authors.

Methods: The output data was extracted from SCOPUS to account for all publications regarding the corneal or ocular surface by Mexican authors. Data screening, extraction, and critical revision were performed by two of the authors to avoid duplication and ensure the authenticity of all papers.

Gene Copy Number Quantification of , , and for the Detection of Sex Chromosome Aneuploidies in Neonates.

To explore the feasibility of detecting sex chromosome aneuploidies (SCAs) by means of gene copy number quantification of short stature homeobox (), vesicle-associated membrane protein 7 (), and in newborns. Gene doses of , , and were determined by quantitative polymerase chain reaction (qPCR) using DNA obtained from dried blood samples from newborns. Relative quantification values were obtained.
