The abdominal compartment is separated from the thoracic compartment by the diaphragm. Under normal circumstances, a large portion of the venous return crosses the splanchnic and nonsplanchnic abdominal regions before entering the thorax and the right side of the heart. Mechanical ventilation may affect abdominal venous return independent of its interactions at the thoracic level. Changes in pressure in the intra-abdominal compartment may have important implications for organ function within the thorax, particularly if there is a sustained rise in intra-abdominal pressure. It is important to understand the consequences of abdominal pressure changes on respiratory and circulatory physiology. This article elucidates important abdominal-respiratory-circulatory interactions and their clinical effects.

Regeneration of Vascular Endothelium in Different Large Vessels.
Int J Mol Sci
January 2025
Department of Cell Biology, IFOM ETS-The AIRC Institute of Molecular Oncology, Via Adamello, 16, 20139 Milan, Italy.
The regeneration of endothelial cells (ECs) lining arteries, veins, and large lymphatic vessels plays an important role in vascular pathology. To understand the mechanisms of atherogenesis, it is important to determine what happens during endothelial regeneration. A comparison of these processes in the above-mentioned vessels reveals both similarities and some significant differences.

UK Health Security Agency, London E14 4PU, UK.
Background: Patients in critical care units (CCUs) are at an increased risk of bloodstream infections (BSIs), which can be associated with central vascular catheters (CVCs). This study describes BSIs, CVC-BSIs, organism distribution, percentage of antimicrobial resistant (AMR) organisms, and case fatality rates (CFRs) over the first six years of a voluntary national CCU surveillance programme in England.
Methods: Surveillance data on BSIs, CVCs, and bed-days between 04/2017 and 03/2023 for adult CCUs were linked to mortality and AMR data, and crude rates were calculated.
Hope for the best, but prepare for the worst - Diagnostic accuracy of the American College of Surgeons National Surgical Quality Improvement Program - Risk model for patients undergoing abdominoplasty after massive weight loss - Results from a Retrospective Cohort Study.
JPRAS Open
March 2025
Department of Orthopaedic, Trauma and Plastic Surgery, University Hospital Leipzig, 04103 Leipzig, Germany.
Background: This study aimed to validate the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) risk calculator for predicting outcomes in patients undergoing abdominoplasty after massive weight loss.
Methods: Patients' characteristics, pre-existing comorbidities and adverse outcomes in our department from 2013 to 2023 were collected retrospectively. Adverse events were defined according to ACS-NSQIP standards and predicted risks were calculated manually using the ACS-NSQIP risk calculator.
An interactive simulator to deepen the understanding of Guyton's venous return curve.
J Physiol Sci

Department of Hematology, Kitasato University School of Medicine, 1-15-1 Kitasato, Minami-Ku, 252-0374, Sagamihara, Kanagawa, Japan.
Mean circulatory filling pressure, venous return curve, and Guyton's graphical analysis are basic concepts in cardiovascular physiology. However, some medical students may not know how to view and interpret or understand them adequately. To deepen students' understanding of the graphical analysis, in place of having to perform live animal experiments, we developed an interactive cardiovascular simulator, as a self-learning tool, as a web application.

Division of Pediatric Cardiology, UT Southwestern, Children's Medical Center, Dallas, TX, USA.
Total anomalous pulmonary venous return (TAPVR) is a high risk and rare cardiac malformation with a low prenatal detection rate and predicting obstruction in these cases is difficult. We sought to investigate fetal echocardiographic parameters associated with postnatal pulmonary venous obstruction (PPVO). We performed a retrospective review of 26 patients with TAPVR who had a fetal echocardiogram from 2010 to 2021.
