Göç ve Çevre Yönetiminin Kamu Politikaları ve Bütçesine Etkileri: Avrupa Birliği ve Üye Ülke Sayıştay Raporlarından Kanıtlar
Yoğunlaşan göç hareketleri ve iklim kriziyle ön plana çıkan sürdürülebilirlik hedefleri, AB ülkelerinde kamu maliyesi üzerinde yeni baskılar yaratarak bütçe denetiminin kapsam ve niteliğini derinlemesine etkilemektedir. Bu çalışma, Avrupa Birliği Sayıştayı ile üye ülkelerin Sayıştay raporları üzerinden, göç ve çevre unsurlarının kamu bütçesi üzerindeki yansımalarını analiz etmektedir. Göçün sosyal hizmetler, sağlık, eğitim ve altyapı harcamaları üzerindeki etkisi ile çevresel politikaların maliyeti, denetim süreçlerinde çok boyutlu değerlendirme gerekliliğini ortaya koymaktadır. Çalışmada, ulaşılan bulgular; göç ve çevre odaklı denetimlerin artış gösterdiğini, bu alanların mali disiplinin yanında sosyal ve ekolojik hedeflerin izlenmesinde de kritik işlev üstlendiğini ortaya koymuştur. Ayrıca raporlar, denetim süreçlerinde entegrasyonun hangi düzeyde gerçekleştiğini ve hangi alanlarda kurumsal kapasite eksikliklerinin bulunduğunu göstermektedir. Bu bağlamda makaledeki analiz, kamu kaynaklarının daha sürdürülebilir, hesap verebilir ve bütüncül biçimde yönetilmesi için AB’de Sayıştay denetim kapasitesinin göç ve çevre unsurlarını kapsar şekilde geliştirilmesinin önemine ve faydasına yönelik somut öneriler sunmaktadır.Intensifying migration flows and climate-driven sustainability goals have placed increasing pressure on public finances in EU countries, reshaping the scope and priorities of budget auditing. This study examines how migration and environmental factors are reflected in public budget audits by analyzing reports from the European Court of Auditors and member states’ supreme audit institutions. The financial implications of migration -particularly in social services, healthcare, education, and infrastructure- along with the rising costs of environmental policies, underscore the need for multidimensional and adaptive auditing frameworks. Through qualitative content analysis, the study finds that audits focusing on migration and environmental issues are growing in number and importance. These audits now serve not only to ensure fiscal discipline but also to track broader social and ecological goals. The reports also expose varying levels of institutional integration and capacity gaps. Accordingly, the article provides concrete policy recommendations to strengthen audit capacities for more sustainable, accountable, and holistic public resource management
Preventive Effect of Er,Cr:YSGG Laser and APF Gel on Enamel Demineralization: An In Vitro Microcomputerized Tomography Study
Identifying the influence of climate policy uncertainty and oil prices on modern renewable energies: novel evidence from the United States
Abstract: The policy uncertainty surrounding climate change can intensify the urgency of implementing climate policies and influence investment decisions, thereby serving as a catalyst for policy transformation. In this context, given its withdrawal from and subsequent re-commitment to the Paris Agreement, the United States (US) may experience policy uncertainty over climate change. Given this backdrop, it is of paramount importance to explore how the uncertainties caused by shifts in climate policy affect clean energy. This study delves into the impact of climate policy uncertainty and oil prices on modern renewable energy sources, such as solar, wind, geothermal, and biofuels. The most recent monthly data from 1989 to 2023 are used by conducting the Residual Augmented Least Squares (RALS) methodology. The empirical findings show that the uncertainty surrounding climate policy is leading to a shift in the US energy composition, with a focus on solar energy, wind energy, and biofuels. Moreover, the fluctuation in oil prices has a significant effect on the deployment of wind and biofuels, but no discernible effect on solar power. These findings provide significant insights for aligning climate policy in the US with Sustainable Development Goal (SDG) 7, highlighting the crucial importance of encouraging investments in solar energy, wind energy, and biofuels.

Post-injection sciatic neuropathy: Effects of intramuscular and intraneural administration of thiocolchicoside in mice
We aimed to investigate whether neuropathic pain post-gluteal injections in mice occurs due to sciatic nerve damage by injector or neurotoxicity of thiocolchicoside (Thio) itself. Acute pain till 48 h post-gluteal injection was analyzed with rot-a-rod, tail-flick, cold-plate, Von-Frey, and paw-grip-endurance tests in no-injection-received control group and intramuscular (IM) and intraneural (IN) Thio or vehicle injection-received mice. Histopathological examination was performed with hematoxylin-eosin staining. Behavioral tests showed that nociceptive parameters and motor functions of mice in IN-injected groups were significantly lower than in IM-injected ones and control group. Behavioral tests performed post-24-h showed no significant difference between control and IM-injected groups. However, IN-injected groups showed marked and consistent differences until 48-h compared to control. The difference between IM-vehicle and IM-Thio groups at early time points revealed partial, temporary neurotoxic effect of Thio. The histopathologic analyses measured degeneration severity and revealed that IN-Thio injections caused the most severe degeneration which aligned with the behavioral tests. We observed mild, temporary pathologic effect of Thio by diffusion on sciatic nerve. IN-injections caused insistent and severe sciatic nerve damage due to mechanical impact. Our results suggest that the prevention of injection-triggered neuropathy requires appropriate injection methods/agents performed by experienced medical personnel
Association of Heart Rate Recovery Assessed by Cardiopulmonary Exercise Testing With Periprocedural Myocardial Infarction After an Elective Percutaneous Coronary Intervention
Aim/Background: Periprocedural myocardial infarction (PMI) remains a significant complication of elective percutaneous coronary intervention (PCI) procedures and is linked to increased morbidity and mortality. Heart rate recovery (HRR), reflecting autonomic function and parasympathetic reactivation, has been established to predict adverse cardiovascular outcomes. This study investigates the association between HRR, assessed through cardiopulmonary exercise testing (CPET), and the occurrence of PMI in patients undergoing elective PCI. Materials and Methods: This retrospective observational study included 401 patients who underwent elective PCI between January 2022 and September 2024. HRR was measured at 1- and 3-min intervals following CPET. Baseline demographic, clinical, and laboratory data were analyzed alongside procedural variables. PMI was defined based on the Fourth Universal Definition of Myocardial Infarction. Statistical analyses, including multivariate logistic regression and receiver operating characteristics (ROC) curve analysis, were performed to assess the predictive value of HRR. Results: Patients with PMI exhibited significantly lower HRR at both 1 min (11.12 ± 3.25 vs. 14.21 ± 4.22, p < 0.001) and 3 min (42.99 ± 13.17 vs. 48.36 ± 9.72, p < 0.001) after peak exercise compared to those without PMI. ROC analysis revealed HRR as a reliable predictor of PMI, with AUCs of 0.723 (1 min) and 0.616 (3 min). Multivariate analysis confirmed HRR at 1 min (OR: 0.744, 95% CI: 0.617–0.897, p = 0.002) and 3 min (OR: 0.950, 95% CI: 0.905–0.999, p = 0.044) as independent predictors of PMI. Conclusion: HRR measured by CPET independently predicts PMI in patients undergoing elective PCI. Incorporating HRR into preoperative risk assessments could enhance clinical decision-making and improve procedural outcomes. Future studies are needed to explore its integration into standard PCI protocols for better risk stratification
