Widefield Swept-Source OCTA Findings in HELLP Syndrome: Choroidal Infarcts.

Purpose: Pre-eclampsia, eclampsia, and hemolysis, elevated liver enzymes, and low platelets (HELLP) syndrome have been previously implicated with ophthalmic complications including serous retinal detachments and disorders of the choroidal vasculature. Herein, we report a case of macular serous detachment associated with HELLP syndrome in which wide field swept-source optical coherence tomography angiography (WF SS-OCTA) was used.

Methods: Retrospective case report of a patient who developed HELLP syndrome.

Age-associated clonal B cells drive B cell lymphoma in mice.

Although cancer is an age-related disease, how the processes of aging contribute to cancer progression is not well understood. In this study, we uncovered how mouse B cell lymphoma develops as a consequence of a naturally aged system. We show here that this malignancy is associated with an age-associated clonal B cell (ACBC) population that likely originates from age-associated B cells.

Lasmiditan ameliorates serotonergic itch in mice: Possible involvement of 5-HT1F receptors.

Previously, some allergic conditions involving pruritus have been linked to migraine, raising the possibility that migraine and itching may be governed by similar underlying mechanisms. We aimed to investigate the efficacy of Lasmiditan, a highly selective agonist of the 5-hydroxytryptamine 1F (5-HT1F) receptor and a recently approved medication for the treatment of migraine headaches, in ameliorating serotonergic itching. Forty animals were employed in the present study (n = 40).

Phenotype Distinctions in Mice Deficient in the Neuron-Specific α3 Subunit of Na,K-ATPase: 3 and .

is a Na,K-ATPase gene expressed specifically in neurons in the brain. Human mutations are dominant and produce an unusually wide spectrum of neurological phenotypes, most notably rapid-onset dystonia parkinsonism (RDP) and alternating hemiplegia of childhood (AHC). Here we compared heterozygotes of two mouse lines, a line with little or no expression (3) and a knock-in expressing p.

Systematic data analysis pipeline for quantitative morphological cell phenotyping.

Quantitative morphological phenotyping (QMP) is an image-based method used to capture morphological features at both the cellular and population level. Its interdisciplinary nature, spanning from data collection to result analysis and interpretation, can lead to uncertainties, particularly among those new to this actively growing field. High analytical specificity for a typical QMP is achieved through sophisticated approaches that can leverage subtle cellular morphological changes.

Camera-based near-infrared autofluorescence versus visual identification in total thyroidectomy for parathyroid function preservation: Systematic review and meta-analysis of randomized clinical trials.

Background: Hypocalcemia is the most common postoperative complication of total thyroidectomy. Near-infrared autofluorescence (NIRAF) technology is a surgical adjunct that has been increasingly utilized with the aim of preventing postoperative hypocalcemia, but its clinical benefits have not yet been firmly established. The aim of this study was to assess the clinical benefit of utilizing NIRAF technology in patients undergoing total thyroidectomy.

Purinergic agonists increase [Ca] in rat conjunctival goblet cells through ryanodine receptor type 3.

ATP and benzoylbenzoyl-ATP (BzATP) increase free cytosolic Ca concentration ([Ca]) in conjunctival goblet cells (CGCs) resulting in mucin secretion. The purpose of this study was to investigate the source of the Ca mobilized by ATP and BzATP. First-passage cultured rat CGCs were incubated with Fura-2/AM, and [Ca] was measured under several conditions with ATP and BzATP stimulation.

The INMSG Survey on the Loss of Signal Management on the First Side During Planned Bilateral Thyroid Surgery.

Background: The aim of this study is to describe the management and associated follow-up strategies adopted by thyroid surgeons with different surgical volumes when loss of signal (LOS) occurred on the first side of planned bilateral thyroid surgery, and to further define the consensus on intraoperative neuromonitoring (IONM) applications.

Methods: The International Neural Monitoring Study Group (INMSG) web-based survey was sent to 950 thyroid surgeons worldwide. The survey included information on the participants, IONM team/equipment/procedure, intraoperative/postoperative management of LOS, and management of LOS on the first side of thyroidectomy for benign and malignant disease.

An enhancer-AAV toolbox to target and manipulate distinct interneuron subtypes.

In recent years, we and others have identified a number of enhancers that, when incorporated into rAAV vectors, can restrict the transgene expression to particular neuronal populations. Yet, viral tools to access and manipulate fine neuronal subtypes are still limited. Here, we performed systematic analysis of single cell genomic data to identify enhancer candidates for each of the cortical interneuron subtypes.

A novel artificial intelligence model for diagnosing Acanthamoeba keratitis through confocal microscopy.

Purpose: To develop an artificial intelligence (AI) model to diagnose Acanthamoeba keratitis (AK) based on in vivo confocal microscopy (IVCM) images extracted from the Heidelberg Retinal Tomograph 3 (HRT 3).

Methods: This retrospective cohort study utilized HRT 3 IVCM images from patients who had received a culture-confirmed diagnosis of AK between 2013 and 2021 at Massachusetts Eye and Ear. Two cornea specialists independently labeled the images as AK or nonspecific finding (NSF) in a blind manner.

Cytokines in PD-1 immune checkpoint inhibitor adverse events and implications for the treatment of uveitis.

Immune checkpoint inhibitors (ICI) such as Programmed cell Death 1 (PD-1) inhibitors have improved cancer treatment by enhancing the immune system's ability to target malignant cells. Their use is associated with immune-related adverse events (irAEs), including uveitis. The profile of pro-inflammatory cytokines underlying Anti-PD-1-induced uveitis shares significant overlap with that of non-infectious uveitis.

Common Practice Patterns in the Diagnosis and Management of Acute Retinal Necrosis: A Survey Study of Uveitis Specialists.

Purpose: Due to lack of large randomized clinical trials to determine best practices in treating acute retinal necrosis (ARN), there is not a clear consensus amongst ophthalmologists on how to best manage this potentially blinding condition. The aim of this study is to survey common practice patterns and analyze the factors that affect ophthalmologists' management of ARN.

Methods: An anonymous survey was distributed to uveitis and retina specialists who are members of the American Uveitis Society (AUS) via email to query practice patterns regarding ARN.

The Influence of Impedance on the Efficacy of Radiofrequency Ablation for Benign Thyroid Nodules.

Objective: Radiofrequency ablation (RFA) uses the heat generated by a high-frequency alternating electric current, and according to Ohm's and Joule's law, the delivered current is inversely proportional to the circuit impedance. The primary objective of this study was to investigate whether tissue impedance during radiofrequency ablation (RFA) for benign thyroid nodules is related to the degree of volume reduction.

Methods: This observational study included consecutive patients treated with RFA for benign thyroid nodules from February 2020 to August 2023.
