Glutathione (GSH), the most abundant intracellular antioxidant, plays a central role in maintaining redox homeostasis, regulating immune responses, and protecting cellular integrity. In chronic diseases such as type 2 diabetes mellitus (T2DM), GSH deficiency is a consistent hallmark, contributing to oxidative stress, mitochondrial dysfunction, inflammation, and progressive organ damage. This review critically examines the efficacy and safety of GSH supplementation and precursor strategies, synthesizing evidence across mechanistic studies, clinical trials, and translational research. In T2DM, GSH augmentation has been linked to improved insulin sensitivity, reduced oxidative damage, and better microvascular outcomes, although findings remain preliminary and heterogeneous. Safety profiles across populations are highly favorable, with gastrointestinal discomfort being the most reported adverse effect and serious toxicities rare. Importantly, both acute and chronic studies reinforce the compatibility of GSH and its precursors with standard antiretroviral and antidiabetic therapies. Despite this encouraging data, significant research gaps remain. Standardization of biomarkers, dose–response mapping, and long-term outcomes are urgently needed to move from proof-of-concept to clinical trials. Future directions include integrating mechanistic endpoints such as mitochondrial function and multi-omic profiling, exploring targeted delivery systems, and embedding implementation science to ensure real-world feasibility and equity. Collectively, the emerging evidence supports GSH-centered strategies as promising adjuncts for oxidative stress-driven chronic disease. Rigorous, well-designed trials are now required to define their definitive role in clinical care.

Glutathione (GSH), the most abundant intracellular non-protein thiol, is a central regulator F redox homeostasis, immune function, and mitochondrial integrity. In human immunodeficiency virus (HIV) infection, persistent oxidative stress and impaired precursor availability result in sustained glutathione deficiency, contributing to immune dysfunction, inflammation, and disease progression despite effective antiretroviral therapy. This redox imbalance is further exacerbated in HIV–tuberculosis co-infection, where compounded inflammatory and metabolic stress increases susceptibility to opportunistic infections and treatment-related complications. This review examines the efficacy and safety of glutathione supplementation and precursor-based strategies in HIV infection and HIV–tuberculosis co-infection. Evidence from mechanistic studies, clinical trials, and translational research suggests that glutathione repletion, achieved through direct supplementation or precursor approaches such as N-acetylcysteine, Glycine and N-acetylcysteine (GlyNAC), and cysteine-rich dietary interventions, can restore intracellular thiol balance, improve immune cell function, enhance mitochondrial performance, and reduce systemic oxidative stress. These interventions have shown consistent safety and tolerability across diverse populations, including individuals receiving complex antiretroviral and antitubercular regimens, with gastrointestinal discomfort being the most commonly reported adverse effect and serious toxicities remaining rare. Despite encouraging findings, translation into routine clinical practice remains limited by methodological heterogeneity, short study durations, and lack of standardized biomarkers and long-term outcome data. Future research should prioritize rigorously designed trials incorporating mechanistic endpoints, standardized redox measurements, and clinically meaningful outcomes. Collectively, the available evidence supports glutathione-centered strategies as promising adjuncts to existing HIV and tuberculosis treatment paradigms, warranting further investigation to define their role in improving immune resilience and long-term clinical outcomes.

Tuberculosis and coronavirus disease 2019, also known as COVID-19, remain major global health challenges that disproportionately affect individuals with metabolic disorders, chronic inflammation, and limited access to healthcare. Although these diseases are caused by different pathogens, they share important host-related determinants of severity, including immune dysfunction, oxidative stress, endothelial injury, and maladaptive inflammatory responses. Glutathione, the primary intracellular antioxidant and a key regulator of redox balance, has emerged as an important host factor connecting these processes across infectious diseases. This review integrates experimental, translational, and clinical evidence supporting the role of glutathione in regulating immune function, oxidative stress, and tissue damage in tuberculosis and COVID-19. In tuberculosis, glutathione deficiency compromises macrophage antimicrobial activity, disrupts granuloma structure, and alters T helper cell responses, leading to impaired immune containment and disease progression. In COVID-19, reduced glutathione levels are associated with redox imbalance, excessive cytokine signaling, endothelial dysfunction, and thromboinflammatory complications, especially in high-risk populations. In both diseases, glutathione depletion reduces host resilience and increases vulnerability to severe outcomes through shared immune and vascular pathways. By unifying disease-specific findings within a host-directed framework, this review highlights glutathione and redox signaling as common vulnerability pathways that help explain overlapping risk profiles for severe tuberculosis and COVID-19. It also places glutathione biology within the broader context of host-directed immunotherapy, emphasizing its potential role in prevention-focused and resilience-based strategies that complement pathogen-targeted treatments. Although current evidence does not support simple claims of disease prevention, it provides strong mechanistic justification for further investigation of glutathione as a modifiable host factor in high-risk populations.

Inguinal hernia represents a multifactorial condition driven by extracellular matrix (ECM) dysregulation, collagen imbalance, and oxidative stress. Across studies, a consistent reduction in the collagen I:III ratio, coupled with altered expression of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs), underpins weakened fascia and hernia susceptibility. Aging further impairs ECM remodeling through fibroblast senescence, cross-linking deficits, and elastic fiber attrition, while oxidative stress and inflammation amplify tissue degradation and impair repair mechanisms. Evidence from clinical and experimental studies underscores the interplay between surgical technique, mesh choice, redox balance, and recurrence risk. Understanding the combined impact of aging and oxidative stress provides a mechanistic framework for targeted therapeutic and surgical strategies aimed at preventing hernia development and recurrence.

Memory, the ability to store and recall information over time, is an imperative component of our everyday lives. At first glance, the process of memorization might only be tied to studying and/or learning, but in reality, memory recall impacts every aspect of our lives. Something as simple as knowing a friend’s name, requires memory recall. Hence, scientists have extensively studied memory and classified it into 3 major memory processes: encoding, retention, and recall. However, not much research has been done to determine whether the type of information that one is exposed to impacts memory recall. In this study, we investigated whether teenagers’ memory recall was stronger for narrative writing or informational writing. We hypothesized that healthy male and female teenagers ages 13–19 would recall more information from narrative writing than informational writing since narrative writing promotes an emotional response. We tested this hypothesis on a group of 30 participants who read one narrative and one informational piece in counterbalanced order. After each reading period, they were given a memory test to assess their memory recall. Our results supported our hypothesis; we found that on average the participants were able to recall more information from the piece of narrative writing than the informational one. These results are significant as they indicate that emotional response could contribute to improved memory recall.
