Coronavirus disease (COVID-19) is an infectious disease caused by SARS-CoV-2. Elderly people, people with immunodeficiency, autoimmune and malignant diseases, as well as people with chronic diseases have a higher risk of developing more severe forms of the disease. Pregnant women and children can becomesick, although more often they are only the carriers of the virus. Recent studies have indicated that infants can also be infected by SARS-CoV-2 and develop a severe form of the disease with a fatal outcome. Acute Respiratory Distress Syndrome (ARDS) ina pregnant woman can affect the supply of oxygen to the fetus and initiate the mechanism of metabolic disorders of the fetus and newborn caused by asphyxia. The initial metabolic response of the newborn to the lack of oxygen in the tissues is the activation of anaerobic glycolysis in the tissues and an increase in the concentration of lactate and ketones. Lipid peroxidation, especially in nerve cells, is catalyzed by iron released from hemoglobin, transferrin and ferritin, whose release is induced by tissue acidosis and free oxygen radicals. Ferroptosis-inducing factors can directly or indirectly affect glutathione peroxidase through various pathways, resulting in a decrease in the antioxidant capacity and accumulation of lipid reactive oxygen species (ROS) in the cells, ultimately leading to oxidative cell stress, and finally, death. Conclusion: damage to the mitochondria as a result of lipid peroxidation caused by the COVID-19 disease can cause the death of a newborn and pregnant women as well as short time and long-time sequelae.

Endothelial dysfunction (characterized by reduced vasodilation or vasoconstriction, oxidative stress, inflammation, and pro-thrombotic condition) is a critical factor in the pathophysiology of various cardiovascular conditions, and the application of anesthetics can affect this dysfunction. Patients undergoing major surgery, especially cardiovascular surgery, are at increased risk of endothelial dysfunction. The impact of anesthetics on endothelial function can vary depending on the specific agent, dosage, duration of exposure, comorbidities, etc. Certain anesthetics, especially at higher doses, may increase the production of reactive oxygen species (ROS), leading to oxidative stress and endothelial dysfunction through reduced nitric oxid (NO) availability. Some anesthetics can modulate inflammatory responses, either by suppressing or exacerbating inflammation, or may affect the permeability of the endothelium, potentially leading to pulmonary edema and disruption of the blood-brain barrier. Anesthetics can influence endothelial glycocalyx. Understanding anesthetics effects is crucial for optimizing anesthetic management, particularly in patients with pre-existing cardiovascular issues. Therefore, the aim of this review is to critically evaluate the effects of different classes of anesthetics on endothelial function and oxidative stress. Specifically, we address how anesthetics influence NO bioavailability, endothelial glycocalyx integrity, inflammatory and oxidative pathways, and clinical outcomes in surgical patients. By summarizing current evidence, we aim to highlight mechanistic insights and identify potential perioperative strategies to minimize endothelial dysfunction.

Background: Patients with acute pancreatitis develop numerous complications and organ damage due to increased intra-abdominal pressure (IAP). These extrapancreatic complications determine the clinical outcome of the disease. Materials and methods: A total of 100 patients with acute pancreatitis were included in the prospective cohort study. Observed patients were divided into two groups according to their mean values of IAP (normal IAP values and elevated IAP values), which were compared with examined variables. Patients with intra-abdominal hypertension (IAH) were divided into four groups by IAP values, and those groups of patients were also compared with the examined variables. Results: Differences between body mass index (BMI) (p = 0.001), lactates (p = 0.006), and the Sequential Organ Failure Assessment (SOFA) score (p = 0.001) were statistically significant within all examined IAH groups. Differences between the mean arterial pressure (MAP) (p = 0.012) and filtration gradient (FG) (p < 0.001) were statistically significant between the first and second IAH groups in relation to the fourth. Differences in diuresis per hour (p = 0.022) showed statistical significance in relation to the first and third groups of IAH patients. Conclusions: Changes in IAP values lead to changes in basic vital parameters MAP, APP, FG, diuresis per hour, and lactate levels in patients with acute pancreatitis. Early recognition of changes in the SOFA score accompanying an increase in the IAP value is essential.

Background: Sepsis remains a leading cause of morbidity and mortality in critically ill patients, often complicated by sepsis-induced myopathy (SIM), systemic inflammation, and multiorgan dysfunction. Glucagon-like peptide-1 receptor agonists (GLP-1RAs), initially developed for the treatment of type 2 diabetes, have demonstrated pleiotropic effects that may be beneficial in the septic context. Objective: This review aims to explore the significance of GLP-1 receptors in the sepsis mechanism, as well as the therapeutic potential of GLP-1RAs in sepsis treatment, with a particular emphasis on their role in modulating inflammation, improving metabolic and endothelial function, and mitigating systemic inflammatory response syndrome (SIRS). Methods: A comprehensive synthesis of preclinical and clinical studies was conducted, focusing on the cellular mechanisms and systemic outcomes of GLP-1RA therapy in various models of sepsis and critical illness. Results: GLP-1RAs attenuate inflammation by suppressing NF-κB and p38 MAPK pathways, reduce oxidative stress, enhance insulin sensitivity, and promote mitochondrial and endothelial stability. In skeletal muscle, they downregulate atrophy-associated genes (MuRF1, MAFbx) and upregulate myogenic factors (MyoD, MyoG), thereby improving perfusion and energy metabolism. Central GLP-1R signaling plays a crucial role in neuroimmune modulation and organ protection. Notably, these agents also increase adiponectin levels, which may further contribute to vascular integrity and anti-inflammatory effects during sepsis. Conclusion: GLP-1RAs represent a novel and multifaceted therapeutic strategy for sepsis and its complications. They show promise as adjunctive therapy in sepsis due to their anti-inflammatory, antioxidant, and endothelial-protective actions. Experimental and limited clinical data suggest improved organ function and survival, but further human studies are needed to confirm efficacy, safety, and optimal treatment strategies.

Background: Many European countries’ epidemiological data on burns were analyzed. This research aimed to analyze the key epidemiological characteristics of hospitalized burn patients in Serbia’s major burn unit over 10 years, as well as to create the very first national epidemiological dataset with the basic requirements for future epidemiological studies. Methods: A retrospective cross-sectional study was conducted, and demographic, clinical, and burn characteristics, as well as predictors of mortality, were analyzed. Results: A total of 996 patients were included. The mean age of the population was 54.65 ± 27.15 years. Regarding etiology, flame was the most common (49.0%). Patient comorbidities were noted on admission in 50.1% of cases. The mean % of total burn surface area (TBSA) was 16.89 ± 18.72%. Inhalation injury was confirmed in 7.5% of patients, and a total of 10.3% of patients required mechanical ventilation during hospitalization. The requirement for mechanical ventilation support was the strongest independent predictor of mortality, while other independent predictors of mortality were male gender, higher %TBSA, deep burns, mechanism of injury, an extended total length of stay (LOS), the occurrence of complications during hospitalization, and conservative treatment modalities. Conclusion: Burn injury mortality remains high, and %TBSA, burn depth, mechanical ventilation requirement, inhalation injury, and the presence of comorbidities on admission unfavorably influence mortality rates.
