Changes in the Microcirculation and Physiologic Perfusion Dynamics of Free DIEP Flaps in the First 72 h After Breast Reconstruction.

The autologous reconstruction of the female breast using a microsurgical DIEP flap is a reliable and safe method. To detect impairments early and preserve the microvascular flap through timely revision, a better understanding of physiologic perfusion dynamics is necessary. This exploratory study examines changes in microcirculation in free DIEP flaps within the first 72 h after vascular anastomosis using laser Doppler flowmetry and white-light spectrophotometry.

Diversity, connectivity and negative interactions define robust microbiome networks across land, stream, and sea.

In this era of rapid global change, factors influencing the stability of ecosystems and their functions have come into the spotlight. For decades the relationship between stability and complexity has been investigated in modeled and empirical systems, yet results remain largely context dependent. To overcome this we leverage a multiscale inventory of fungi and bacteria ranging from single sites along an environmental gradient, to habitats inclusive of land, sea and stream, to an entire watershed.

Impact of Synchronized Radiofrequency and High-Intensity Facial Electrical Stimulation on Facial Muscles and the Superficial Fascial System in the Midface.

Background: Midfacial aging involves skeletal changes, muscle weakening, and fat redistribution, resulting in volume loss, skin sagging, and deepened nasolabial folds. High-Intensity Facial Electrical Stimulation (HIFES) combined with Radiofrequency (RF) is a novel non-invasive method to address these changes by enhancing muscle mass and remodeling subcutaneous tissue.

Objectives: To assess the efficacy of HIFES and Synchronized RF in improving midfacial aesthetics, specifically muscle thickness, skin displacement, and facial volume.

Left of sternum compressions are associated with higher systolic blood pressure than lower half of sternum compressions in cardiac arrest.

Introduction: Limited evidence supports guidelines to perform chest compressions at the lower half of the sternum. Imaging studies suggest this location may obstruct blood flow. Our primary aim was to compare the highest arterial line systolic blood pressure (SBP) during lower-half-of-sternum chest compressions (CC) versus those left-of-sternum, where the left ventricle is more likely located.

Vertex Augmentation With Hyaluronic Acid Filler: A Novel Technique for Height Enhancement and Cephalic Contouring.

Height augmentation and cephalic contouring using hyaluronic acid (HA) fillers represent an innovative approach in minimally invasive aesthetic medicine. This study introduces a novel technique for vertex augmentation, leveraging cross-linked HA fillers to achieve subtle height enhancement and cephalic contouring. A 42-year-old male patient seeking non-surgical height augmentation underwent vertex injections with 15 ml of HA filler (e.
