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.

Aspirin Inhibits the In Vitro Adipogenic Differentiation of Human Adipose Tissue-Derived Stem Cells in a Dose-Dependent Manner.

Aspirin (ASA) is one of the most used medications worldwide and has shown various effects on cellular processes, including stem cell differentiation. However, the effect of ASA on adipogenesis of adipose tissue-derived stem cells (ASCs) remains largely unknown. Considering the potential application of ASCs in regenerative medicine and cell-based therapies, this study investigates the effects of ASA on adipogenic differentiation in human ASCs.

Ultrahypofractionated Versus Normofractionated Preoperative Radiotherapy for Soft Tissue Sarcoma: A Multicenter, Prospective Real-World-Time Phase 2 Clinical Trial.

The historically most commonly used preoperative radiotherapy regimen for soft tissue sarcomas (STSs) consists of 50 Gray (Gy) delivered in 25 fractions over 5 weeks, achieving excellent local control, but with significant challenges due to prolonged treatment duration and early side effects. Reducing therapy duration while maintaining optimal local and distant control would be highly beneficial for patients. We aimed to investigate the outcome of an ultrahypofractionated radiotherapy (uhRT) regimen which may represent a shorter and more patient-friendly alternative.

Enhancing Patient Experience in Sarcoma Core Biopsies: The Role of Communication, Anxiety Management, and Pain Control.

This study evaluates the effectiveness of communication strategies and pain management protocols to enhance patients' experiences during sarcoma core biopsies. Recognizing the complexity and anxiety associated with sarcoma diagnoses, this research aims to assess the utility of the Invasive Procedure Assessment (IPA) tool, focusing on its ability to identify areas for improvement through Patient-Reported Outcome Measures (PROMs) and Patient-Reported Experience Measures (PREMs). Conducted at two Integrated Practice Units (IPUs) within the Swiss Sarcoma Network, this study involved 282 consecutive patients who underwent core biopsies.

Dnmt3a-mediated methylation balances memory Th1 and Tfh cell plasticity and functionality.

Following acute viral infection, naïve CD4+ T cells differentiate into T follicular helper (Tfh) and T helper 1 (Th1) cells that generate long-lived memory cells. However, it is unclear how memory Tfh and Th1 cells maintain their lineage commitment. Here we demonstrate that Tfh and Th1 lineages acquire distinct DNA methylation programs that are preserved into memory.
