In survey-weighted fully adjusted models, high screen exposure was associated with increased odds of type 2 diabetes (OR 3.47, 95% CI 2.74–4.36). Sleep duration was not independently associated with type 2 diabetes, while diagnosed sleep disorders were associ…
In a case-control study, prolonged nighttime device use (>4 h), high blue-light display patterns, and use of nightlights during sleep were significantly associated with depressive symptoms in adolescents, independent of demographic and sleep-related factors; …
This narrative review reports that prolonged and inappropriate mobile phone use, especially in the evening/pre-bedtime period, is associated with circadian rhythm disruption (described as blue light–induced melatonin suppression) and with delayed sleep onset,…
In a cross-sectional survey of 463 undergraduates in the UAE, 35.4% reported a diagnosed eye disorder and common symptoms included headaches (43.8%), neck/back pain (38.2%), eye strain (37.6%), and dry eyes (37.1%). Symptom scores were higher among females an…
Blue light at 405, 420, and 450 nm produced wavelength- and dose-dependent inactivation of multiple food-related bacteria. At the same dose, lower wavelengths achieved greater reductions; 405 nm showed the highest inactivation overall (e.g., ~7.5 log CFU/mL r…
Embryos incubated under different light spectra showed a significant increase in telomere length across early development independent of spectrum. Red light and darkness were described as potent stressors (proteotoxic stress and energy imbalance), while green…
Primary human gingival fibroblasts showed minor reductions in viability after 457 nm blue light across 3–90 J/cm2, while keratinocyte proliferation and metabolic activity were enhanced. Violet light (415 nm) produced significant cytotoxic effects. Blue light …
In 61 participants (32 with T2D; 29 without), dynamic structural equation modelling identified 18 significant within-person associations between smartphone-derived sleep/movement behaviours and subsequent daily mood; 17 associations indicated a positive effec…
In a within-subjects comparison of short breaks with smartphone use versus sitting quietly, there were no significant differences in mind wandering during breaks, subsequent 2-back task performance, or mind wandering during the subsequent task. Participants r…
Among 408 adolescents (204 males, 204 females), postural assessment showed head anteriorization and pelvic misalignment, with females having greater head and pelvic angular deviations. No significant associations were found between cell phone use and cervical…
In 21 adults using Dexcom G6/G7 or FreeStyle Libre 2/3, median MARD comparing CGM readings during REN ON vs OFF was 1.61% (IQR 0.84–2.44%), significantly below a prespecified 5% threshold (p < 0.001), and all participants had MARD < 5%. No technical interfere…
In 51 patients (153 total assessments), intraobserver agreement between smartphone and PACS review was substantial for fracture classification (k=0.72), general treatment (k=0.79), and specific treatment (k=0.76). Image quality rated poor/unacceptable did not…
In a blue light-induced retinal damage mouse model, Abelmoschus manihot flower extract (AME) pretreatment preserved photoreceptor layer structure, maintained outer segment and synaptic ribbon architecture, and reduced 8-OHdG accumulation. In 661W photorecepto…
