Deficiency Insufficient selenium intake may negatively affect the activity of several selenium-responsive enzymes, including glutathione peroxidases (specifically, GPx1 and GPx3), iodothyronine deiodinases, selenoprotein W, and methionine-R-sulfoxide reductase B1 (MsrB1)
1 Introduction Diabetic retinopathy (DR), a leading cause of vision impairment among working-age adults, affects approximately 146 million individuals globally, with projections estimating an increase to 180 million by 2030, driven by the rising prevalence of diabetes, particularly in low- and middle-income countries ( The pathophysiology of early DR involves a complex interplay of hyperglycemia-induced microvascular damage, inflammation, oxidative stress, and advanced glycation end product (AGE) accumulation ( Advances in diagnostic technologies, including ultra-widefield fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA), and artificial intelligence (AI)-based algorithms, have revolutionized early NPDR detection, achieving over 95% accuracy and enabling prediction of systemic risks ( This review synthesizes the molecular basis of early-stage DR, compares its pathophysiology between T1DM and T2DM, evaluates diagnostic innovations, and explores therapeutic advancements supported by recent clinical trials and real-world data
The Oral Alternative: Why NAC Wins on Evidence If your primary goal is raising intracellular glutathione, N-acetylcysteine (NAC) has stronger clinical evidence and has far more predictable pharmacokinetics than SubQ glutathione injection
PD affects 1% of the general population over the age of 60
