Prospective Multi-Site Validation of AI to Detect Tuberculosis and Chest X-Ray Abnormalities.

Background: Using artificial intelligence (AI) to interpret chest X-rays (CXRs) could support accessible triage tests for active pulmonary tuberculosis (TB) in resource-constrained settings.

Methods: The performance of two cloud-based CXR AI systems - one to detect TB and the other to detect CXR abnormalities - in a population with a high TB and human immunodeficiency virus (HIV) burden was evaluated. We recruited 1978 adults who had TB symptoms, were close contacts of known TB patients, or were newly diagnosed with HIV at three clinical sites.

In vivo 9.4 Tesla MRI of a patient with drug-resistant epilepsy: Technical report.

Purpose: In resective epilepsy surgery for drug-resistant focal epilepsy (DRE), good seizure outcome is strongly associated with visualization of an epileptogenic lesion on MRI. Standard clinical MRI (≤ 3 Tesla (T)) may fail to detect subtle lesions. 7T MRI enhances detection and delineation, the potential benefits of increasing field strength to 9.

Circulating Adenoid Cystic Carcinoma associated MYB transcripts enable rapid and sensitive detection of metastatic disease in blood liquid biopsies.

Adenoid cystic carcinoma (ACC) is a rare and lethal malignancy that originates in secretory glands of the head and neck. A prominent molecular feature of ACC is the overexpression of the proto-oncogene MYB. ACC has a poor long-term survival due to its high propensity for recurrence and protracted metastasis.

Adult and pediatric orbital rhabdomyosarcoma: comparison of characteristics and outcomes.

Introduction: Rhabdomyosarcoma (RMS) is a common pediatric orbital malignancy but is extremely rare in adults. This study assesses clinical and radiographic features, management, and outcomes in adult orbital RMS patients with comparison to pediatric patients.

Methods: A retrospective chart review from 2000-2023 at Bascom Palmer Eye Institute was conducted evaluating patients aged 0 to 100-years-old with biopsy-confirmed orbital RMS.

A journey towards a trauma informed and responsive Justice system: the perspectives and experiences of senior Justice workers.

There is a risk of re-traumatisation for survivors of trauma who engage with the Justice system, given their high propensity to encounter situations that trigger traumatic responses. While a growing body of research has explored the experience of trauma informed practice (TIP) from service user perspectives, little research has incorporated the views and experiences of practitioners working in the Justice system in terms of the implementation of TIP in their service setting. An exploratory, qualitative research design based on semi-structured, in-depth interviews.

Methods: Twenty mice underwent sonication-inducted traumatic optic neuropathy. Afterward, 10 mice were placed on a warming pad set to 36°C, and 10 mice were placed on a table.

Thrombospondin 1 Mediates Autophagy Upon Inhibition of the Rho-Associated Protein Kinase Inhibitor.

Age-related macular degeneration (AMD) is a degenerative eye disease leading to central vision loss and is characterized by dysregulated autophagy of the retinal pigment epithelium (RPE) layer. Recent studies have suggested that rho-associated protein kinase (ROCK) inhibitors may enhance autophagy in neurodegenerative diseases and promote the survival of RPE cells. This study investigated the effect of ROCK inhibitors on autophagy gene expression and autophagic vacuole formation in a human RPE (ARPE-19) cell line.

Circulating Adenoid Cystic Carcinoma associated MYB transcripts enable rapid and sensitive detection of metastatic disease in blood liquid biopsies.

Adenoid cystic carcinoma (ACC) is a rare and lethal malignancy that originates in secretory glands of the head and neck. A prominent molecular feature of ACC is the overexpression of the proto-oncogene MYB. ACC has a poor long-term survival due to its high propensity for recurrence and protracted metastasis.

Competence of Senior Otolaryngology Residents with the Bedside Head Impulse Test-Has There Been Improvement After 5 Years of Competency By Design?

Background: The bedside head impulse test (bHIT) is a clinical method of assessing the vestibulo-ocular reflex. It is a critical component of the bedside assessment of dizzy patients and helps differentiate acute stroke from vestibular neuritis. A previous study on senior Otolaryngology residents showed poor competence in performing and interpreting the bHIT and called for specific evaluations in the Competency By Design (CBD) curriculum to remedy this.

People who share encounters with racism are silenced online by humans and machines, but a guideline-reframing intervention holds promise.

Are members of marginalized communities silenced on social media when they share personal experiences of racism? Here, we investigate the role of algorithms, humans, and platform guidelines in suppressing disclosures of racial discrimination. In a field study of actual posts from a neighborhood-based social media platform, we find that when users talk about their experiences as targets of racism, their posts are disproportionately flagged for removal as toxic by five widely used moderation algorithms from major online platforms, including the most recent large language models. We show that human users disproportionately flag these disclosures for removal as well.

Capturing Successful Aging in Daily Life: Exploring the Intensive Longitudinal Findings From a U.S. National Sample.

Background And Objectives: Thus far, successful aging has been conceptualized and operationalized as a relatively static construct. Investigating daily successful aging provides a dynamic approach highlighting how successful aging can be achieved through everyday actions, giving older adults a stronger sense of control over their lives.

Research Design And Methods: We used 8-day diary data from Midlife in the United States 2's U.

Periocular granulomatous inflammatory lesions mimicking conjunctival melanoma recurrence in the setting of systemic nivolumab treatment.

Purpose: Conjunctival melanoma is a rare neoplasm with high rates of recurrence and metastasis. Traditional management includes surgical excision and cryotherapy, followed by adjuvant therapy as needed. Immune checkpoint inhibitors, including nivolumab, are a targeted treatment option with improved survival rates.

Misremembering Solitude: The Role of Personality and Cultural Self-Concepts in Shaping Discrepancies Between Recalled and Concurrent Affect in Solitude.

Background: Affect recall is key to psychological assessment and decision-making. However, self-concepts (self-beliefs) may bias retrospective affect reports such that they deviate from lived experiences. Does this experience-memory gap apply to solitude experiences? We hypothesized that individuals misremember how they feel overall and when in solitude, in line with self-concepts of introversion, self-determined/not-self-determined solitude motivations, and independent/interdependent self-construal.

Optic Nerve Amyloid Deposition Disguised as Optic Nerve Sheath Meningioma.

Localized orbital amyloidosis is a rare clinical entity. Periocular and orbital amyloid deposits are mainly located at the lacrimal apparatus, eyelid, conjunctiva, ocular adnexa, extraocular muscles, and levator palpebrae muscle. In this article, the authors report an unusual case of optic nerve amyloid deposition in an 82-year-old African American woman who presented with vertical diplopia.

Study Objective: Identify high-risk clinical characteristics for a serious cause of vertigo in patients presenting to the emergency department (ED).

Methods: Multicentre prospective cohort study over 3 years at three university-affiliated tertiary care EDs. Participants were patients presenting with vertigo, dizziness or imbalance.

A high-resolution 7 Tesla resting-state fMRI dataset optimized for studying the subcortex.

To achieve a comprehensive understanding of spontaneous brain dynamics in humans, acquisition of intrinsic activity across both cortical and subcortical regions is necessary. Here we present advanced whole-brain, resting-state functional magnetic resonance imaging (rs-fMRI) data acquired at 7 Tesla with 1.5 mm isotropic voxel resolution.

Cultural Differences in Daily Coupling of Subjective Views of Aging and Negative Affect.

Objectives: The established link between subjective views of aging (VoA) and well-being shows variations across different cultures. Although VoA show daily fluctuations, little is known about cultural differences in such fluctuations and the daily coupling of VoA and well-being. We compared Israeli Arabs to Israeli Jews in the daily coupling of VoA and negative affect (NA).

Reducing discrepancies between actual and ideal affect across adulthood: the roles of activity flow conduciveness, pleasantness, and familiarity.

Previous findings demonstrate that people often do not feel how they want to feel, supporting the distinction between "actual affect" and "ideal affect." But are there certain activities that reduce the discrepancy between actual and ideal affect? Based on flow theory and socioemotional selectivity theory, we examined whether the discrepancy between people's actual and ideal positive affect would be smaller during activities that were more conducive to flow (a state of intense absorption and concentration), pleasant, and familiar. In Study 1, U.

Combination effect of optical defocus and low dose atropine in myopia control: Study protocol for a randomized clinical trial.

Background: Myopia, characterized by excessive axial elongation of the eyeball, increases risks of having sight-threatening diseases and impose a financial burden to healthcare system. Although myopic control interventions showed their effectiveness in slowing progression, the efficacy varies between individuals and does not completely halt progression. The study aims to investigate the efficacy of combining 0.

Strategies to address inequity of uncorrected refractive error in the Western Pacific: A modified Delphi process.

Purpose: Uncorrected refractive error is the leading cause of vision impairment globally; however, little attention has been given to equity and access to services. This study aimed to identify and prioritise: (1) strategies to address inequity of access to refractive error services and (2) population groups to target with these strategies in five sub-regions within the Western Pacific.

Methods: We invited eye care professionals to complete a two-round online prioritisation process.

Coenzyme Q10 eyedrops conjugated with vitamin E TPGS alleviate neurodegeneration and mitochondrial dysfunction in the diabetic mouse retina.

Diabetic retinopathy (DR) is a leading cause of blindness and vision impairment worldwide and represents one of the most common complications among diabetic patients. Current treatment modalities for DR, including laser photocoagulation, intravitreal injection of corticosteroid, and anti-vascular endothelial growth factor (VEGF) agents, target primarily vascular lesions. However, these approaches are invasive and have several limitations, such as potential loss of visual function, retinal scars and cataract formation, and increased risk of ocular hypertension, vitreous hemorrhage, retinal detachment, and intraocular inflammation.
