Article Abstract
Introduction: Accurate positioning of central venous catheter (CVC) tips is essential to minimize complications such as arrhythmias, thrombosis, or cardiac tamponade.
Methods: This study evaluated the reliability of the Peres formula, which estimates CVC tip placement based on patient height, within an Iranian population. A cross-sectional analysis of 100 patients undergoing cardiac surgery revealed that the Peres formula often resulted in incorrect CVC positioning, necessitating radiographic confirmation and post-insertion adjustments.
Results: The mean deviation of CVC tip placement from the ideal position near the carina was 5.13±0.78 cm. Correlation analysis highlighted significant associations between the deviation and demographic factors, including height and body mass index (BMI), suggesting the need for population-specific adjustments to the Peres formula.
Conclusion: These findings underscore the importance of tailored approaches to CVC placement to account for anatomical and physiological differences, emphasizing the need for modified guidelines for the Iranian population to enhance safety and accuracy in clinical practice due to the fact that Peres formula is not suitable for Iranian population.

Objectives: Preventive efforts and early diagnosis of erosive tooth wear (ETW) are essential to minimize damage to dental hard tissues. In addition to controlling etiological factors, the synergistic action of specific agents can help maintain oral health. This study aimed to evaluate the ability of bioactive varnishes to prevent and/or control the progression of ETW on enamel.

The potential of insects as alternative ingredients in animal feeds is well-established. However, limited information is available on the use of insect oils as alternative lipid sources in aquafeeds. To address this, a study was conducted on gilthead seabream (Sparus aurata) juveniles to evaluate the effects of including black soldier fly (Hermetia illucens) larvae oil (HIO).

Hermetia illucens larvae oil (HIO) is a promising new ingredient that can potentially be an alternative lipid source in aquafeeds. To assess its viability in gilthead seabream juvenile diets, a 10-week feeding trial was performed, and the effects on antioxidant, immune, and inflammatory responses were evaluated. Four diets were formulated to include HIO at increasing levels: 0, 4, 7.
