Minimizing central nervous system (CNS) injury from preterm birth depends upon understanding the critical pathways that underlie essential neurodevelopmental and CNS pathophysiology. Signaling by chemokine (C-X-C motif) ligand 1 (CXCL1) through its cognate receptor, CXCR2 [(C-X-C motif) receptor 2] is essential for neurodevelopment. Increased CXCR2 signaling, however, is implicated in a variety of uterine and neuropathologies, and their role in the CNS injury associated with perinatal brain injury is poorly defined.

Preclinical studies show that ClC-1 inhibition enhances muscle excitability, improving muscle contractility and strength. We describe the first-in-human, randomized, double-blind, placebo-controlled study, which evaluated the safety, pharmacokinetics, and pharmacodynamics of single and multiple doses of NMD670 in healthy male and female subjects.

Materials And Methods: Data from adults aged 17-79 years were extracted from the Hong Kong Territory-Wide Physical Fitness Survey conducted in 2011-2012 and 2021-2022. Moderate to vigorous physical activity (MVPA) patterns were collected through questionnaires and categorized as inactive (no MVPA ≥10 min), insufficiently active (<150 min MVPA/week), weekend warriors (≥150 min MVPA/week from 1 to 2 days) and regularly active (≥150 min MVPA/week from ≥3 days).
Cyclic guanosine monophosphate (GMP)-adenosine monophosphate (AMP) synthase (cGAS) is an enzyme sensor of double-stranded DNA (dsDNA) that serves to trigger activation of the cGAS-stimulator of interferon genes (STING) pathway. Excessive activation of this pathway has been demonstrated to contribute to various forms of inflammatory disease. As such, cGAS has arisen as a potential therapeutic target with broad potential applications.

The presentation of vitamin A deficiency (VAD)-induced ocular complications can be challenging to diagnose in elderly patients, particularly due to the overlap with age-related macular degeneration (AMD) symptoms. This case report details the presentation, diagnosis, and management of an 88-year-old female with vision loss, highlighting the ocular manifestations of presumed VAD. Despite vitamin A levels being at the lower end of the normal range, the patient's symptoms and spectral domain optical coherence tomography (SD-OCT) findings suggested insufficient levels, leading to thinning of the outer nuclear layer.
