Vitamin A supply in the eye and establishment of the visual cycle.

Animals perceiving light through visual pigments have evolved pathways for absorbing, transporting, and metabolizing the precursors essential for synthesis of their retinylidene chromophores. Over the past decades, our understanding of this metabolism has grown significantly. Through genetic manipulation, researchers gained insights into the metabolic complexity of the pathways mediating the flow of chromophore precursors throughout the body, and their enrichment within the eyes.

Hepatitis C Treatment in Kentucky Medicaid Recipients with Concurrent Opioid Use Disorder: A Cross-Sectional Study.

Background: Hepatitis C virus (HCV) infections and injection drug use have concurrently increased in the last decade. Evidence supports simultaneously treating chronic HCV and opioid use disorder (OUD) with medication. Kentucky is a hard-hit state for both conditions that has undertaken policy and practice efforts to increase access to both types of medications.

Implementation of carceral medicaid suspension and enrollment programs: perspectives of carceral and medicaid leaders.

Background: Medicaid expansion via the Affordable Care Act, more recent legislation and Medicaid 1115 waivers offer opportunity to increase health care access among individuals involved in the carceral system. Effective enrollment of new beneficiaries and temporary suspension and reactivation of existing Medicaid benefits upon release is key to the success of these efforts. This study aims to characterize how jails, prisons and Medicaid agencies are implementing Medicaid suspension and enrollment programs and identifies barriers and facilitators to implementation.

Use of isavuconazole in mucormycosis: a systematic review.

Background: Mucormycosis is an opportunistic fungal infection which is associated with poor prognosis. Only a few antifungals are available in the arsenal against mucormycosis. The global guidelines for diagnosing and managing mucormycosis recommend high doses of liposomal amphotericin B (LAmB) as the first-line treatment.

Epidemiological patterns and trends of paediatric snakebites in Sri Lanka.

Objectives: This study aimed to analyse the epidemiological patterns of paediatric snake bites in Sri Lanka over a 4-year period (2020-2024).

Methods: A multi-centre, retrospective observational study was conducted from June 2020 to June 2024 across nine governmental hospitals in seven provinces of Sri Lanka. Data were collected based on 757 children presenting with snake bites.
