Fiscal Antibodies: How Public Health Expenditures Strengthen National Economic Vulnerability to Climate Change
(Multidisciplinary Digital Publishing Institute (MDPI), 2026-06-12) Abdelmoneim Bahyeldin Mohamed Metwally; Mai M. Yasser
This study investigates the relationship between public health expenditures and national climate vulnerability, measured by the Notre Dame Global Adaptation Initiative (ND-GAIN) Index, across 62 developed and developing countries from 2000 to 2023. Motivated by contradictory findings in the prior literature and a lack of large-scale panel econometric evidence, this research aims to determine whether health investments significantly increase climate vulnerability. Using a dynamic generalized method of moments (GMM), the findings show that public health expenditure per capita has a statistically significant positive impact on the ND-GAIN composite index. Findings show that public health expenditure per capita has a statistically significant positive impact on the ND-GAIN composite index—where higher ND-GAIN values indicate lower climate vulnerability and greater adaptive capacity—implying that increased public health spending is associated with reduced national climate vulnerability. In high-income countries, health spending may improve adaptive capacity by leveraging established infrastructure and governance. As a result, policymakers should make funding for public health a top priority in their plans for adapting to climate change. This is because investing in health alone is not enough; they also need to invest in infrastructure, governance, and adaptive capacity, especially in developing countries.
Drivers of Institutional Sustainability in Egyptian and Saudi Universities: A Comparative Mixed-Methods Analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2026-06-09) Abdulrahman Saleh Aldogiher; Yasser Tawfik Halim; Ahmed Mostafa Maree; Esmat Mostafa Kamel
Purpose: This study investigates the multifaceted dynamics of institutional sustainability (IS) within the higher education sectors of Saudi Arabia and Egypt. It examines the direct influence of cultural, technological, and economic factors, alongside change management techniques (CMT), on the sustainability of universities in these two nations. Methodology: Employing a comparative, mixed-methods approach, the research collected data from 427 university staff members across Saudi Arabia and Egypt. Structural Equation Modeling (PLS-SEM) was utilized for data analysis, complemented by Multiple Group Analysis (MGA) to explore variations across different demographics, including gender, geographical location, and institution type (public vs. private). Findings: The study reveals that Change Management Techniques (CMT), cultural norms, technological infrastructure, and economic factors all significantly and directly influence institutional sustainability. Effective CMT is crucial for successful technological integration and mitigating staff resistance. Cultural norms, particularly in high power distance and collectivist societies, profoundly impact the adoption of innovations. A robust technological infrastructure is foundational for operational efficiency and educational outcomes, while strategic economic planning and diversified funding streams are vital for long-term stability and growth. Originality: This research offers actionable insights for policymakers and academic leaders by providing a nuanced understanding of how to build resilient, sustainable, and technologically advanced educational institutions in the Middle East. It emphasizes the necessity of context-specific strategies that acknowledge the unique regional socio-cultural and economic realities of Saudi Arabia and Egypt, bridging the gap between global sustainability paradigms and local implementation challenges.
Understanding the governance–disclosure nexus: board attributes, ownership structure and carbon emission disclosure in Egypt
(Emerald Publishing, 2026-06-04) Mohamed Samy El-Deeb; Habiba Ezzat
Purpose: The aim of this research is to investigate the influence of board of directors' characteristics (BODC) on carbon emission disclosure (CED) and determine whether the relationship between BODC and CED is moderated by institutional ownership (IO) for Egyptian listed firms. This research particularly explores the effects of board size, independence, gender diversity and nationality diversity on CED. Design/methodology/approach: The empirical analysis is based on 51 EGX70-listed non-financial companies between 2019 and 2023, which provides 255 firm-year observations. The data were obtained through the board reports, ESG disclosures and audited financial statements. A system generalized approach of moments (GMM) is used to conquer endogeneity issues and this approach is supplemented by two-stage least squares (2SLS) estimator and hypothesis are then tested. Findings: The findings show that board size negatively affects CED, board independence positively affects CED and gender diversity also affects CED in a positive way. Diversity in board nationality is also found to have negative relationships with CED, which can be explained by the unfamiliarity with the culture and regulation. These relationships are also largely moderated by institutional ownership, which reduces the negative influence of board size and enhances the positive effect of board independence. The results indicate the importance of the board composition in promoting transparency of the environment of Egyptian listed firms. Practical implications: The study provides valuable insights to market regulators, corporate boards and investors in emerging markets. The study provides insights to market regulators such as the Financial Regulatory Authority (FRA) to improve ESG mandates as suggested by El-Deeb et al. (2023). The study provides insights to corporate boards to improve gender diversity and independence to improve environmental transparency. The study also provides insights to investors to improve market efficiency by leveraging ownership stakes to improve stakeholder interests as suggested by Siew et al. (2016). Originality/value: This study investigates the moderating role of institutional ownership in the relationship between board characteristics – size, independence, gender and nationality diversity – and carbon emission disclosure in Egypt. It provides novel evidence from an emerging market shaped by recent ESG reforms and COP27, showing that institutional investors enhance board effectiveness while nationality diversity may hinder transparency, extending legitimacy, stakeholder and resource-based perspectives.
Mechanistic evidence for PI3K/Akt-driven reactivation of Nrf2/HO-1 by dapagliflozin in acute cisplatin hepatotoxicity
(Oxford University Press, 2026-06-21) Doaa Abou El-ezz; Noha E Ibrahim; Marwan Khaled Fouad; Marwan A Abd El-Baset; Heba Shawky
Background: While nephrotoxicity remains the most recognized adverse effect of cisplatin, hepatotoxicity is increasingly acknowledged as a significant clinical concern. Objective: This study evaluated the hepatoprotective effect of dapagliflozin (DAPA), a selective sodium–glucose cotransporter-2 inhibitor, focusing on its modulation of the PI3K/Akt–Nrf2/HO-1 signaling pathway. Methods: Male Wistar albino rats received oral dapagliflozin (5 or 10 mg/kg/day) for 14 days, with a single intraperitoneal injection of cisplatin (7.5 mg/kg) administered on Day 7. Biochemical, molecular, and histopathological assessments were conducted. Results: Cisplatin induced marked hepatic injury, evidenced by body weight loss, hepatomegaly, hyperglycemia, impaired liver function, oxidative stress, inflammation, and apoptosis dysregulation. Dapagliflozin pretreatment significantly and dose-dependently mitigated these effects. It reduced lipid peroxidation and nitric oxide levels while enhancing antioxidant defenses, including Nrf2, heme oxygenase-1, and superoxide dismutase. Additionally, dapagliflozin restored PI3K/Akt signaling, suppressed NF-κB-mediated inflammatory responses, and normalized apoptotic balance. Histological findings corroborated biochemical results, showing preservation of hepatic architecture, particularly at the higher dose. Conclusions: Dapagliflozin exerts significant hepatoprotective effects against cisplatin-induced toxicity via antioxidant, anti-inflammatory, and cytoprotective mechanisms, supporting its potential as an adjunct to improve cisplatin safety.
Efficacy of High-Intensity Laser Therapy for Meralgia Paresthetica: A Randomized, Double-Blind, Sham-Controlled Trial
(Lippincott Williams and Wilkins Ltd., 2026-06-04) Mogahed, Hussein G.; ElMeligie, Mohamed M.; Radwan, Rafik E.; Elmahdy, Menan A.; Abdel-Aal, Nabil M.; Mohamed, Mahmoud H.
Objective: To evaluate High-Intensity Laser Therapy (HILT) versus sham for pain, function, and nerve conduction in Meralgia Paresthetica (MP). Design: Randomized, double-blind, sham-controlled trial. Methods: Patients with MP (n=62 randomized, n=54 analyzed) received 12 sessions of HILT (1064 nm, 12 W, 600 J/cm²) or identical sham over 4 weeks. Primary outcome: Numeric Pain Rating Scale (NPRS). Secondary outcomes: Lower Extremity Functional Scale (LEFS), lateral femoral cutaneous nerve sensory conduction velocity (SNCV), and SF-36, assessed at baseline, weeks 4, 8, and 12. Results: At week 12, HILT demonstrated significantly greater improvements versus sham in pain (NPRS, P=0.006), function (LEFS, P=0.043), and SNCV (P=0.027). SNCV showed small but significant between-group differences favoring HILT, though values remained within normal limits. Mild, transient adverse events occurred more frequently with HILT (16.1% vs. 0%, P=0.0525). Conclusion: HILT significantly improved pain, function, and nerve conduction velocity compared to sham in MP patients over 12 weeks. These findings support HILT as a non-invasive treatment option; neurophysiological changes were small and within normative limits, warranting cautious interpretation.
