[Diabetic retinopathy and pregnancy].

This article reviews the critical issue of diabetic retinopathy (DR) in pregnant women with diabetes mellitus (DM), and describes the current understanding of the features of DM progression during pregnancy, as well as its pathogenic mechanisms, risk factors, and preventive measures for manifestation and progression of DR during gestation.

[Risk factors associated with myopic maculopathy in acquired myopia].

Purpose: This study aimed to identify factors associated with the development of myopic maculopathy (MM) in patients with acquired myopia.

Material And Methods: The study included a total of 135 patients (41 men, 94 women; 135 eyes) over 30 years old with acquired myopia and axial length (AL) of 26 mm. Forty-six patients had MM, while 89 (66%) had no macular changes.

Genetic Evidence for Distinct Biological Mechanisms That Link Adiposity to Type 2 Diabetes: Toward Precision Medicine.

We aimed to unravel the mechanisms connecting adiposity to type 2 diabetes. We used MR-Clust to cluster independent genetic variants associated with body fat percentage (388 variants) and BMI (540 variants) based on their impact on type 2 diabetes. We identified five clusters of adiposity-increasing alleles associated with higher type 2 diabetes risk (unfavorable adiposity) and three clusters associated with lower risk (favorable adiposity).

Precision MRI phenotyping of muscle volume and quality at a population scale.

Magnetic resonance imaging (MRI) enables direct measurements of muscle volume and quality, allowing for an in-depth understanding of their associations with anthropometric traits, and health conditions. However, it is unclear which muscle volume measurements: total muscle volume, regional measurements, measurements of muscle quality: intermuscular adipose tissue (IMAT) or proton density fat fraction (PDFF), are most informative and associate with relevant health conditions such as dynapenia and frailty. We have measured image-derived phenotypes (IDPs) including total and regional muscle volumes and measures of muscle quality, derived from the neck-to-knee Dixon images in 44,520 UK Biobank participants.
