Safety and Efficacy of Traditional Heart Failure Therapies in Patients With Cardiac Amyloidosis and Heart Failure.

Randomized controlled trials have demonstrated mortality benefits for several medication classes in patients with heart failure (HF), especially with reduced ejection fraction (EF). However, the benefit of these traditional HF therapies in patients with HF from cardiac amyloidosis is unclear. our study aimed to evaluate the safety and efficacy of traditional HF therapies in patients with cardiac amyloidosis and HF with reduced EF or HF with mid-range EF (HFmrEF).

Spatial Transcriptomics Identifies Expression Signatures Specific to Lacrimal Gland Adenoid Cystic Carcinoma Cells.

Although primary tumors of the lacrimal gland are rare, adenoid cystic carcinoma (ACC) is the most common and lethal epithelial lacrimal gland malignancy. Traditional management of lacrimal gland adenoid cystic carcinoma (LGACC) involves the removal of the eye and surrounding socket contents, followed by chemoradiation. Even with this radical treatment, the 10-year survival rate for LGACC is 20% given the propensity for recurrence and metastasis.

An Elderly Man with Atypical Multiple Evanescent White Dot Syndrome.

A rare occurrence of an atypical case of multiple evanescent white dot syndrome (MEWDS) in a 75-year-old man without viral prodrome or white dots on fundus that presented with acute, severe left eye visual loss, which returned to baseline without treatment in several weeks. Multimodal imaging, including fluorescein angiography (FA), fundus autofluorescence (FAF), indocyanine green angiography (ICG), and optical coherence tomography (OCT) demonstrated classical presentation of MEWDS with wreath-like lesions and inflammatory foci in the retinal pigment epithelium that correlated among modalities. Possible underlying systemic disorders were ruled out through extended work up.

Early Mechanisms of Chemoresistance in Retinoblastoma.

Retinoblastoma is the most common eye cancer in children and is fatal if left untreated. Over the past three decades, chemotherapy has become the mainstay of eye-sparing treatment. Nevertheless, chemoresistance continues to represent a major challenge leading to ocular and systemic toxicity, vision loss, and treatment failure.

Derivation and Characterization of Murine and Amphibian Müller Glia Cell Lines.

Purpose: Müller glia (MG) in the retina of Xenopus laevis (African clawed frog) reprogram to a transiently amplifying retinal progenitor state after an injury. These progenitors then give rise to new retinal neurons. In contrast, mammalian MG have a restricted neurogenic capacity and undergo reactive gliosis after injury.

A novel pathogenic variant at the C-terminal propeptide cleavage site of COL1A1, causing osteogenesis imperfecta with intrafamilial variability.

Osteogenesis imperfecta (OI) is a rare connective tissue disorder with clinical and genetic heterogeneity. The cardinal features of OI are bone fragility and low bone mineral density (BMD). Pathogenic variants in COL1A1 and COL1A2 genes, which encode the proα-1(I) and proα-2(I) chains of Type 1 collagen, are the most common causes of OI.

Effects of Mitomycin-C and 5-Fluorouracil on Ocular Adnexal Sebaceous Carcinoma Cells.

Purpose: To investigate the effects of mitomycin-C (MMC) and 5-fluorouracil (5-FU) on the viability, proliferation, and migratory capacity of cultured ocular adnexal sebaceous carcinoma (SC) cells.

Design: Laboratory investigation.

Methods: Human SC cell lines (Bascom Palmer 50 and 52 [BP50 and BP52]) and human limbal stem cells (LSCs) were treated with various concentrations of MMC and 5-FU.

Establishment and Characterization of a Novel Human Ocular Adnexal Sebaceous Carcinoma Cell Line.

Purpose: Sebaceous carcinoma (SC) is a malignant eyelid tumor of the ocular adnexa that is primarily treated via surgical excision. Few therapies exist in advanced cases, and medical therapy is limited because of our incomplete understanding of SC biology. Herein, we describe a technique to culture human ocular adnexal SC for use as an in vitro model.

Fedratinib-induced orbital inflammation.

A 69-year-old man with myelofibrosis presented with a two-day history of left periorbital swelling, blurred vision, and non-radiating dull orbital pain. On examination, there was restricted left-sided extraocular motility with conjunctival injection, chemosis, and periorbital edema. Magnetic resonance imaging demonstrated left-sided pre- and post-septal fat stranding concerning for orbital cellulitis.

Integrating Differential Gene Expression Analysis with Perturbagen-Response Signatures May Identify Novel Therapies for Thyroid-Associated Orbitopathy.

Purpose: To evaluate the efficacy of Library of Integrated Network-based Cellular Signatures (LINCS) perturbagen prediction software to identify small molecules that revert pathologic gene signature and alter disease phenotype in orbital adipose stem cells (OASCs) derived from patients with thyroid-associated orbitopathy (TAO).

Methods: Differentially expressed genes identified via RNA sequencing were inputted into LINCS L1000 Characteristic Direction Signature Search Engine (L1000CDS) to predict candidate small molecules to reverse pathologic gene expression. TAO OASC cell lines were treated in vitro with six identified small molecules (Torin-2, PX12, withaferin A, isoliquiritigenin, mitoxantrone, and MLN8054), and expression of key adipogenic and differentially expressed genes was measured with quantitative polymerase chain reaction after 7 days of treatment.
