Tapentadol is a unique opioid analgesic due to its dual mechanism of action. Compared to other opioids with a classical mechanism of action, its analgesic potential is not far behind them, and its advantages are: a better safety profile in terms of a lower potential for drug-drug interactions and a lower potential for causing adverse events, and it is safe to use in sensitive populations. Tapentadol in the form of a immediate release formulation is an adequate drug of choice for achieving a pharmacotherapeutic analgesic response in acute pain conditions, while in the form of a extended release formulation it is an adequate pharmacotherapeutic analgesic solution for chronic pain syndromes of various etiology.

The incorporation of bevacizumab, a monoclonal antibody targeting vascular endothelial growth factor (VEGF), has redefined therapeutic strategies for advanced ovarian cancer. This study evaluates the efficacy of bevacizumab combined with standard chemotherapy by comparing progression-free survival (PFS) and overall survival (OS) outcomes with a historical cohort of patients treated with standard chemotherapy alone. We conducted an analysis of 71 patients with advanced epithelial ovarian cancer treated at the University Clinical Center in Niš, Serbia, from April 2017 to March 2023.

Article Synopsis
  • Tryptase is a key biomarker for diagnosing severe allergic reactions like anaphylaxis and is also important in assessing other mast cell-related conditions.
  • The paper highlights two clinical cases to demonstrate the significance of timely measuring serum tryptase during hypersensitivity reactions and emphasizes its broader clinical uses.
  • A detailed literature review identified crucial guidelines for interpreting serum tryptase levels, suggesting that elevated levels indicate a higher risk for severe reactions and necessitate further investigation and management.

Background: Post-operative atrial fibrillation (POAF) is a frequent complication after cardiac surgery. It is associated with prolonged hospital stay, increased morbidity, mortality rate and economic costs. The aim of the study was to determine the association between the values of Galectin3 and N-terminal pro-B-type natriuretic peptide (NTproBNP) with POAF after cardiac surgery.

Article Synopsis
  • - The study compared the prevalence of potentially inappropriate drug prescriptions between hemodialysis patients and those with chronic kidney disease not requiring renal replacement therapy, using the 2015 AGS Beers criteria to determine appropriateness.
  • - Conducted in Serbia, the research included 218 patients aged 65 and older, finding that about one-third in both groups had potentially inappropriate prescriptions, with no significant difference between the two groups (32.5% vs. 32.6%).
  • - Key factors contributing to inappropriate prescribing included the number of medications and comorbidities; for hemodialysis patients, both factors were important, while only the number of drugs influenced patients without renal replacement therapy.

Background: In the present study, two structurally similar alkaloids from trees of Cinchona genus, chloroquine and cinchonine, were examined for their vasorelaxant effects in a model of phenylephrine-induced smooth muscle contractions.

Methods: Potential mechanisms of action associated with endothelial vasorelaxant compounds, voltage-gated Ca2+ channels (LTCCs), and inositol triphosphate receptors were examined in isolated rat aortic rings. Also, an in silico approach was used to predict the activity of the two test compounds.

Article Synopsis
  • Catalase and glutathione peroxidase (GPx) are key antioxidant enzymes that help control hydrogen peroxide levels in cells, and their dysfunction can lead to oxidative stress.
  • Research indicates that patients with schizophrenia have impaired activity of these enzymes, with conflicting findings on their levels in various studies.
  • This study measured the activity of catalase and GPx in 68 schizophrenia inpatients compared to 59 healthy controls, revealing significantly lower levels in patients, with some dependence on the severity and duration of symptoms.

: Women with cervical cancer may experience depression or anxiety, influencing their quality of life and even their adherence to cancer treatments. This study aimed to explore and measure the levels of anxiety and depression in patients suffering from cervical cancer and to identify the possible predictors among known risk factors such as age, cancer stage, smoking status, number of partners, use of contraceptives, and annual gynecological visits. : In total, 59 patients with cervical cancer were included.

Introduction: Antioxidants such as lycopene (LCP) and caffeic acid phenethyl ester (CAPE) represent ideal molecules for the treatment of different reactive oxygen species (ROS) associated disorders. Cisplatin is a chemotherapeutic agent, causing an increase in ROS and DNA damage, with numerous side effects, which include lung toxicity. In the presents study, we evaluated and mutually compared the potential of LCP and CAPE in preventing cisplatin-induced rat lung damage.

Aim: Carbon tetrachloride (CCl4) is an organic chemical that produces different tissue‑damaging effects when ingested or inhaled. Present study aims to determine whether the application of exogenous melatonin, a neurohormone with numerous biological properties, can prevent disturbances in lung tissue antioxidative capacities and arginine metabolism, tissue inflammation and oxidative damage induced by exposure to CCl4 in rats.

Methods: The effects of melatonin on the changes occurring in rat lung tissue after an acute exposure to CCl4 were studied by monitoring alterations in antioxidant capacities, inflammatory parameters, parameters of arginine metabolism, and lipid and protein oxidative damage.

Up to this date, there has been an ongoing debate about the mode of action of general anesthetics, which have postulated many biological sites as targets for their action. However, postoperative nausea and vomiting are common problems in which inhalational agents may have a role in their development. When a mode of action is unknown, QSAR modelling is essential in drug development.
