Effect of electrodeposition time on physical characteristics and antibacterial activity of copper-incorporated TiO nanotubes.

The current work outlines the preparation of a TiO nanotube (NT) layer electrochemically formed on the surface of a clinically-relevant titanium alloy anodisation. This NT layer was subsequently modified alternating current electrodeposition to incorporate copper micro- and nanoparticles on top of and within the NTs. Physical characterisation of the NT layer and the copper-incorporated NTs was carried out through analysis of the surface morphology, elemental composition, crystallinity, and stability SEM, EDX, XRD, and ICP-OES, respectively.

Foveal avascular zone enlargement correlates with visual acuity decline in patients with diabetic retinopathy.

Purpose: The foveal avascular zone (FAZ) area has been explored as a measure of macular ischemia in diabetic retinopathy (DR) but is limited by its wide variability even in healthy individuals. We hypothesized that FAZ enlargement, which we defined as the difference between the functional FAZ (on optical coherence tomography angiography; OCTA) and structural FAZ (en face OCT), may be a more accurate metric of macular ischemia. In this study, we test the hypothesis that FAZ enlargement is associated with decreased best-corrected visual acuity (BCVA) and low luminance visual acuity (LLVA) and performs better than the functional FAZ as a marker of vision loss.

Anaemia during pregnancy: could riboflavin deficiency be implicated?

Anaemia affects more than 36 % of all pregnancies globally and is associated with significant maternal and neonatal morbidity and mortality. Iron deficiency is widely recognised as the most common nutritional cause of anaemia but other nutrient deficiencies are also implicated, including the B vitamin riboflavin, albeit its role is largely under-investigated and thus typically overlooked. Riboflavin, in its co-factor forms flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), is required for numerous oxidation-reduction reactions, antioxidant function and in the metabolism of other B vitamins and iron.

Characteristics of Fatalities Among Sexual- and Gender-Diverse Youth in the United States: 2015-2020.

Objectives: Sexual- and gender-diverse youth face unique stressors that negatively impact their health. The objective of this study was to use National Fatality Review-Case Reporting System data to epidemiologically describe fatalities among identified sexual- and gender-diverse youth to inform future prevention efforts.

Methods: We used 2015 to 2020 data from the National Fatality Review-Case Reporting System to identify deaths among sexual- and gender-diverse youth and compare their characteristics to a matched sample of youth from these same data who were not known to be sexual- and gender-diverse.
