Article Abstract
Purpose: We evaluated racial/ethnic differences in primary open-angle glaucoma (POAG) defined by machine-learning-derived regional visual field (VF) loss patterns.
Methods: Participants (N = 209,036) from the Nurses' Health Study (NHS; 1980-2018), Nurses' Health Study II (NHS2; 1989-2019), and Health Professionals Follow-Up Study (HPFS; 1986-2018) who were ≥40 years of age and free of glaucoma were followed biennially. Incident POAG cases (n = 1946) with reproducible VF loss were confirmed with medical records. Total deviation information from the earliest reliable glaucomatous VF for each POAG eye (n = 2564) was extracted, and machine learning analyses were used to identify optimal solutions ("archetypes") for regional VF loss patterns. Each POAG eye was assigned a VF archetype based on the highest weighting coefficient. Multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using per-eye Cox proportional hazards models.
Results: We identified 14 archetypes: four representing advanced loss patterns, nine of early loss, and one of no VF loss. Compared to non-Hispanic whites, black participants had higher risk of early VF loss archetypes (HR = 1.98; 95% CI, 1.48-2.66) and even higher risk for advanced loss archetypes (HR = 6.17; 95% CI, 3.69-10.32; P-contrast = 0.0002); no differences were observed for Asians or Hispanic whites. Hispanic white participants had significantly higher risks of POAG with paracentral defects and advanced superior loss; black participants had significantly higher risks of all advanced loss archetypes and three early loss patterns, including paracentral defects.
Conclusions: Blacks, compared to non-Hispanic whites, had higher risks of POAG with early central and advanced VF loss.
Translational Relevance: In POAG, risks of VF loss regional patterns derived from machine learning algorithms showed racial differences.

Background: Sedentary behavior (SB) and the absence of physical activity (PA) have become increasingly prevalent in modern societies due to changes in physical and social-environmental conditions, particularly in university students. This cross-sectional study aimed to describe and identify the prevalence and correlates of self-reported and accelerometer-determined SB and PA of German university students.
Methods: A convenience sample of 532 students participated in a questionnaire survey during the lecture period in the summer term 2018.

Cell death in multiple sclerosis.

Multiple sclerosis (MS) is a chronic autoimmune disorder of the central nervous system (CNS) characterized by inflammatory demyelination and progressive neurodegeneration. Although current disease-modifying therapies modulate peripheral autoimmune responses, they are insufficient to fully prevent tissue specific neuroinflammation and long-term neuronal and oligodendrocyte loss. Growing evidence implicates various regulated cell death (RCD) pathways, including apoptosis, necroptosis, pyroptosis, and ferroptosis, not only as downstream consequences of chronic inflammation, but also as active drivers of demyelination, axonal injury, and glial dysfunction in MS.

Background: Cancer screening nonadherence persists among adults who are deaf, deafblind, and hard of hearing (DDBHH). These barriers span individual, clinician, and health care system levels, contributing to difficulties understanding cancer information, accessing screening services, and following treatment directives. Critical communication barriers include ineffective patient-physician communication, limited access to American Sign Language (ASL) cancer information, misconceptions about medical procedures, insurance navigation difficulties, and intersectional barriers for multiply marginalized individuals.

The pyrolysis of flue-cured tobacco stalks (TS) faces challenges such as low bio-oil value and utilization efficiency. Existing studies have overlooked the anatomical heterogeneity of tobacco stalks, thereby limiting the directional regulation of high-value components, such as nicotine and phenolic compounds. This study divides TS into the husk (TSH), xylem (TSX), and pith (TSP), and investigates their physicochemical properties, pyrolysis behavior (through TGA and fixed-bed pyrolysis experiments), and interactions.
