14%/year vs. -3.71%/year, P = 0.008). Moreover, lower baseline VD in the DCP was significantly associated with faster VD reduction in POAG with high myopia eyes (P < 0.001). Conversely, the VD reduction rate in the SCP, FAZ area, and FAZ circularity in both the SCP and DCP were similar in both groups (all Ps > 0.05).

VD in DCP reduced significantly more quickly in POAG eyes with high myopia over time. Density in the DCP reduced more quickly when baseline VD was low.

Thyroid eye disease (TED) is a condition that causes the tissue behind the eye to become inflamed and can result in excessive fatty tissue accumulation in the orbit. Two subpopulations of fibroblasts reside in the orbit those that highly express Thy1 (Thy1+) and those with little or no Thy1 (Thy1-). Thy1- orbital fibroblasts (OFs) are more prone to lipid accumulation than Thy1+ OFs. The purpose of this study was to investigate the mechanisms whereby Thy1- OFs more readily accumulate lipid.

We screened Thy1+ and Thy1- OFs for differences in microRNA (miRNA) expression. selleckchem The effects of increasing miR-130a levels in OFs was investigated by measuring lipid accumulation and visualizing lipid deposits. To determine if adenosine monophosphate-activated protein kinase (AMPK) is important for lipid accumulation, we performed small interfering RNA (siRNA)-mediated knockdown of AMPKβ1. We measured AMPK expression and activity using immunoblotting for AMPK and AMPK target proteins.

We determined that miR-130a was upregulated in Thy1- OFs and that miR-130a targets two subunits of AMPK. Increasing miR-130a levels enhanced lipid accumulation and reduced expression of AMPKα and AMPKβ in OFs. Depletion of AMPK also increased lipid accumulation. Activation of AMPK using AICAR attenuated lipid accumulation and increased phosphorylation of acetyl-CoA carboxylase (ACC) in OFs.

These data suggest that when Thy1- OFs accumulate in TED, miR-130a levels increase, leading to a decrease in AMPK activity. Decreased AMPK activity promotes lipid accumulation in TED OFs, leading to excessive fatty tissue accumulation in the orbit.

There is currently no guidance on how to approach surveillance mammography for older breast cancer survivors, particularly when life expectancy is limited.

To develop expert consensus guidelines that facilitate tailored decision-making for routine surveillance mammography for breast cancer survivors 75 years or older.

After a literature review of the risk of ipsilateral and contralateral breast cancer events among breast cancer survivors and the harms and benefits associated with mammography, a multidisciplinary expert panel was convened to develop consensus guidelines on surveillance mammography for breast cancer survivors 75 years or older. Using an iterative consensus-based approach, input from clinician focus groups, and critical review by the International Society for Geriatric Oncology, the guidelines were refined and finalized.

The literature review established a low risk for ipsilateral and contralateral breast cancer events in most older breast cancer survivors and summarized the benefits andhat these expert guidelines will enhance clinical practice by providing a framework for individualized discussions, facilitating shared decision-making regarding surveillance mammography for breast cancer survivors 75 years or older.

Patients with laryngeal injury after endotracheal intubation often present long after initial injury with mature fibrosis compromising cricoarytenoid joint mobility and glottic function.

To compare functional outcomes between early and late intervention for intubation-related laryngeal injury.

This retrospective cohort study involved 29 patients with laryngeal injury resulting from endotracheal intubation who were evaluated at a tertiary care center between May 1, 2014, and June 1, 2018. Ten patients with intubation injury to the posterior glottis who received early treatment were compared with 19 patients presenting with posterior glottic stenosis who received late treatment. Statistical analysis was performed from May 1 to July 1, 2019.

Early intervention, defined as a procedure performed 45 days or less after intubation, and late treatment, defined as an intervention performed greater than 45 days after intubation.

Patient-specific and intervention-specific covariates were compared between the 2 . These findings may bear relevance to the management of patients requiring extended durations of endotracheal intubation during recovery for critical illness related to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
Many common inherited retinal diseases are not easily treated with gene therapy. Gene editing with base editors may allow the targeted repair of single-nucleotide transition variants in DNA and RNA. It is unknown how many patients have pathogenic variants that are correctable with a base editing strategy.

To assess the prevalence and spectrum of pathogenic single-nucleotide variants amenable to base editing in common large recessively inherited genes that are associated with inherited retinal degeneration.

In this retrospective cross-sectional study, nonidentifiable records of patients with biallelic pathogenic variants of genes associated with inherited retinal degeneration between July 2013 and December 2019 were analyzed using data from the Oxford University Hospitals Medical Genetics Laboratories, the Leiden Open Variation Database, and previously published studies. Six candidate genes (ABCA4, CDH23, CEP290, EYS, MYO7A, and USH2A), which were determined to be the most common recessive genes with coding sequences not deliverable in a single adeno-associated viral vector, were examined.
