AI Article Synopsis
- The study compares the effects of the Trendelenburg position and passive leg raising (PLR) on the size of the right internal jugular vein (IJV) in mechanically ventilated ICU patients.
- Both positions resulted in a significant increase in IJV size compared to the supine position, with a 26% increase in the Trendelenburg position and a 23% increase in the PLR position.
- No significant difference was found between the increases in vein size from either position, suggesting both are effective for central vein catheterization.
Article Abstract
Central vein catheterization is a common procedure performed on patients under intensive care. The safe and successful placement of the central venous catheter depends on vein size. Although used for this purpose, the Trendelenburg position can be hazardous in some patients. The aim of this study was to compare the effects of the Trendelenburg and passive leg raising (PLR) positions on the size of the right internal jugular vein (IJV) in mechanically ventilated patients under intensive care. Seventy-eight mechanically ventilated patients under intensive care were included into the study. Sonographic images of the right IJV were recorded in supine (control), 10° Trendelenburg and 40° PLR positions. Anterior-posterior and transverse diameter, cross-sectional area (CSA), and depth were calculated from the recorded images. The size of the right IJV (CSA, transverse and vertical diameters) was significantly larger in the Trendelenburg and PLR positions than in supine position. An increase of 26% in the IJV CSA was obtained in the Trendelenburg position and 23% in the PLR position, compared to the supine position. There was no significant difference between the measurements obtained from the Trendelenburg and PLR positions. The study shows that the Trendelenburg and PLR positions increase the size of the IJV to a similar extent in mechanically ventilated patients under intensive care.

Background: The diagnosis of rare uterine leiomyosarcoma (uLMS) remains a challenge given the high incidence rates of benign uterine tumors such as leiomyoma (LM). In the last decade, several clinical scores and blood serum markers have been proposed. The aim of this study is to validate and update the pLMS clinical scoring system, evaluating the accuracy of the scoring system by Zhang et al.

Background: Coronary artery disease (CAD) comprises one of the leading causes of morbidity and mortality both in the European population and globally. All established clinical risk stratification scores and models require blood lipids and physical measurements. The latest reports of the European Commission suggest that attracting health professionals to collect these data can be challenging, both from a logistic and cost perspective, which limits the usefulness of established models and makes them unsuitable for population-wide screening in resource-limited settings, i.

Article Synopsis
- The study aimed to investigate how certain blood count-derived immune markers relate to the risk of developing epilepsy over time, using data from a large UK population cohort.
- Researchers analyzed blood cell ratios and counts in nearly 500,000 participants over a median follow-up of about 12 years, noting that a significant number developed epilepsy during this period.
- Key findings indicated that higher levels of specific markers like monocytes and certain ratios (NLR, PLR, SII) were linked to an increased risk of epilepsy, while higher lymphocyte counts and the lymphocyte-to-monocyte ratio (LMR) were associated with a decreased risk.

Background: Subarachnoid block is the most common anesthetic technique for patients having corrective hip surgeries. However, adequate positioning for a successful subarachnoid block is a major challenge in this particular population of patients, owing to the site of fracture. Regional anesthesia, in the form of nerve blocks, is an effective means of alleviating such constraints and gives an added benefit of prolonged postoperative analgesia.
