Background: The antioxidant properties of epigallocatechin-gallate (EGCG), a green tea compound, have been already studied in various diseases. Improving the bioavailability of EGCG by nanoformulation may contribute to a more effective treatment of diabetes mellitus (DM) metabolic consequences and vascular complications. The aim of this study was to test the comparative effect of liposomal EGCG with EGCG solution in experimental DM induced by streptozotocin (STZ) in rats. Method: 28 Wistar-Bratislava rats were randomly divided into four groups (7 animals/group): group 1—control group, with intraperitoneal (i.p.) administration of 1 mL saline solution (C); group 2—STZ administration by i.p. route (60 mg/100 g body weight, bw) (STZ); group 3—STZ administration as before + i.p. administration of EGCG solution (EGCG), 2.5 mg/100 g b.w. as pretreatment; group 4—STZ administration as before + i.p. administration of liposomal EGCG, 2.5 mg/100 g b.w. (L-EGCG). The comparative effects of EGCG and L-EGCG were studied on: (i) oxidative stress parameters such as malondialdehyde (MDA), indirect nitric oxide (NOx) synthesis, and total oxidative status (TOS); (ii) antioxidant status assessed by total antioxidant capacity of plasma (TAC), thiols, and catalase; (iii) matrix-metalloproteinase-2 (MMP-2) and -9 (MMP-9). Results: L-EGCG has a better efficiency regarding the improvement of oxidative stress parameters (highly statistically significant with p-values < 0.001 for MDA, NOx, and TOS) and for antioxidant capacity of plasma (highly significant p < 0.001 for thiols and significant for catalase and TAC with p < 0.05). MMP-2 and -9 were also significantly reduced in the L-EGCG-treated group compared with the EGCG group (p < 0.001). Conclusions: the liposomal nanoformulation of EGCG may serve as an adjuvant therapy in DM due to its unique modulatory effect on oxidative stress/antioxidant biomarkers and MMP-2 and -9.

Measuring patient satisfaction of healthcare service quality represents a significant element of a healthcare’s system (HS) overall evaluation. It is the starting point for creating policies in national healthcare. The purpose of this paper was to evaluate Romanian patients’ perception and satisfaction of the quality of the national HS as a whole and of its components. Exploratory and descriptive research was used. Data were collected through face-to-face interviews with Romanian patients, based on a questionnaire. Out of the 2305 respondents, 83% used the Romanian HS in the past 12 months and 58% of the respondents did not trust the system. The accommodation, food, and other facilities of Romanian hospitals were perceived as being at a low level. One third of the respondents were unsatisfied and very unsatisfied with respect to the overall impression of the Romanian HS. In addition, our research found a statistically significant relationship between confidence in the HS, age, and gender, and also between the overall impression on the HS, age and income.

Introduction: Inflammatory biomarkers, including Interleukin-6 (IL-6) and Tumor Necrosis Factor-alpha (TNF-alpha), play a significant role in influencing stroke outcomes, particularly in the progression of post-stroke disability. While numerous studies have suggested a correlation between elevated levels of these cytokines and poor functional recovery, further investigation is needed to understand their prognostic value in acute ischemic stroke. Materials and Methods: We conducted a prospective study on 56 patients diagnosed with acute ischemic stroke, evaluating IL-6 and TNF-alpha levels on days 1 and 7 post symptom onset. Stroke severity was assessed using the National Institutes of Health Stroke Scale (NIHSS) and functional outcomes were measured with the modified Rankin Scale (mRS). Statistical analyses were performed to evaluate the association between biomarker levels and stroke severity and recovery. Results: Our study demonstrated that elevated levels of IL-6 and TNF-alpha on both days 1 and 7 were significantly correlated with greater stroke severity and poorer functional outcomes, as indicated by higher NIHSS and mRS scores. These findings are consistent with broader research indicating strong associations between inflammatory cytokines and post-stroke disability, further reinforcing their relevance as prognostic indicators. Conclusions: IL-6 and TNF-alpha are promising biomarkers for predicting stroke severity and functional recovery in acute ischemic stroke. Monitoring these cytokines in the early stages of stroke could aid in identifying patients at higher risk for long-term disability, potentially guiding personalized therapeutic strategies. Further research into anti-inflammatory therapies targeting these cytokines may improve stroke rehabilitation and outcomes.

The prevalence of diabetes mellitus (DM) rises constantly each year worldwide. Because of that, the funds allocated for the DM treatment have increased over time. Regarding the number of DM cases, Romania is among the top ten countries in Europe. Based on the National Diabetes Programme (NDP), antidiabetic drugs and other expenditures (Self-monitoring blood glucose (SMBG) test, HbA1c, insulin pumps/insulin pumps supplies) are free of charge. This programme has undergone many changes in drugs supply, in the last two decades: re-organizing the NDP, authorization of new molecules with high prices (e.g., SGLT-2 inhibitors, etc.) or new devices (e.g., insulin pumps, etc.) The main purpose of this study is to identify and analyse the impact of the DM costs on the Romanian health budget and to highlight the evolution of these costs. A retrospective longitudinal research on the official data regarding the DM costs from 2000 to 2017 was performed. The DM funds (DMF) were adjusted with the inflation rate. In this period, the average share of DMF in the total funds allocated for health programmes was 21.3 ± 3.4%, and DMF average growth rate was 25.4% (r = 0.488, p = 0.047). On the other hand, the DMF increased more than 14 times, in spite of the patients’ number having increased only about 2.5 times. Referring to the structure of DMF, the mean value of the antidiabetic drugs cost was of 96,045 ± 67,889 thousand EUR while for other expenditures it was of 11,530 ± 7922 thousand EUR (r = 0.945, p < 0.001). Between 2008 and 2017, the total DMF was 181,252 ± 74,278 thousand EUR/year. Moreover, the average patients’ number was 667,384 ± 94,938 (r = 0.73, p = 0.016), and the cost of treatment was 215 ± 36 EUR/patient/year. Even if the cost is rising, the correct and optimal treatment is a main condition for the diabetic patient’s health and for the prevention of its complications, which have multiple socio-economic repercussions.

Background and Objectives: An increasing incidence of non-melanoma skin cancer (NMSC) is noted, as well as an increasing cost of the treatment, with NMSC becoming a public health problem. We aimed to investigate the prevalence and treatment costs of surgically treated NMSC from the Oral and Maxillofacial Surgery Department of Cluj-Napoca County Hospital. Materials and Methods: We retrospectively analyzed the clinical data and the charge data of hospitalization from the informatic system of Cluj-Napoca County Hospital. All patients benefited from standard surgical excision with the reconstruction of the post-excisional defect. A statistical analysis of the costs related to the patients’ features, period and conditions of hospitalization, materials, medication, and paraclinical investigations was performed. Results: Between 2015 and 2019, 133 patients with NMSC were addressed to our department, with basal cell carcinoma (BCC) being four-fold higher than squamous cell carcinoma (SCC). Most NMSC cases were diagnosed in stage I or II, and they benefited from local reconstruction. The treatment costs progressively increased in the last five years, reaching a total cost of EUR ~13.000 in 2019. The treatment cost per episode was higher for SCC compared to BCC, while the total cost of treatment in 5 years was higher for BCC. Low income, immunosuppression, comorbidities, flap reconstruction option, long-lasting surgery, and prolonged hospitalization were associated with an increased cost of the treatment. Conclusion: The prevalence and treatment cost of surgically treated NMSC of the head and neck region increased in the last five years, with high-cost drivers being related to patients and treatment options.

Background and Objectives: Stroke is a leading cause of mortality and morbidity worldwide. Treatment of this pathology is still under development and its risk factors remain to be determined. Therefore, we aim to determine the role of interleukin-1 beta in atherosclerotic lesions of the internal carotid artery as a risk factor for stroke and the role of this biomarker in stroke prognosis. Materials and Methods: This study enrolled 56 patients diagnosed with ischemic stroke in the anterior vascular territory (AVT) and posterior vascular territory (PVT). All the patients had venous blood collected at admission and 7 days after the onset of the cerebral ischemia in order to determine the plasma concentration of interleukin-1 beta. At the same time, an extracranial carotid ultrasound was performed. Results: The interleukin-1 beta collected at admission was positively correlated with the NIHSS at admission (Pearson index 0.424), and both measurements were correlated with carotid stenosis (Spearmen correlation index of 0.529 and 0.653, respectively). Conclusions: Interleukin-1 beta could be a reliable biomarker for stroke prognosis and the development of atherosclerotic lesions of the internal carotid.
