Partial nephrectomy has become the gold standard treatment for small renal masses. This study aimed to assess the impact of soft coagulation hemostasis on parenchymal volume reduction of the operated kidney after an open partial nephrectomy. We retrospectively reviewed 94 patients with small renal tumors who underwent open partial nephrectomy with soft-coagulation hemostasis at our institution.

The Complex Role of Matrix Metalloproteinase-2 (MMP-2) in Health and Disease.

Int J Mol Sci

December 2024

Pittsburgh Heart, Lung and Blood Vascular Medicine Institute (VMI), University of Pittsburgh School of Medicine, Pittsburgh, PA 15260, USA.

Matrix metalloproteinase-2 (MMP-2), a zinc-dependent enzyme, plays a critical role in the degradation and remodeling of the extracellular matrix (ECM). As a member of the gelatinase subgroup of matrix metalloproteinases, MMP-2 is involved in a variety of physiological processes, including tissue repair, wound healing, angiogenesis, and embryogenesis. It is primarily responsible for the degradation of type IV and V collagen, fibronectin, laminin, and elastin, which are essential components of the ECM.

Megakaryocyte in sepsis: the trinity of coagulation, inflammation and immunity.

Crit Care

December 2024

Medical Innovation Research Division and Fourth Medical Center of Chinese, PLA General Hospital, State Key Laboratory of Trauma and Chemical Poisoning, Beijing, 100853, China.

Background: Megakaryocytes are traditionally recognized as cells responsible for platelet production. However, beyond their role in thrombopoiesis, megakaryocytes also participate in inflammatory responses and regulate immune system functions. Sepsis, characterized by life-threatening organ dysfunction due to a dysregulated response to infection, prominently features coagulopathy, severe inflammation, and immune dysfunction as key pathophysiological aspects.

Background: Preeclampsia (PE) is a pregnancy complication characterized by hypertension, proteinuria, endothelial dysfunction, and complement dysregulation. Placenta-derived extracellular vesicles (EVs), necessary in maternal-fetal communication, might contribute to PE pathogenesis. Moreover, neutrophil extracellular traps (NETs) play a pathogenic role in other complement-mediated pathologies, and their contribution in PE remains unexplored.

Introduction: During hemodialysis (HD), the presence of clots in the dialyzer can diminish the effective surface area of the device. In severe cases, clot formation in the circuit can halt treatment and lead to blood loss in the system. Thus, ensuring proper anticoagulation during HD is crucial to prevent clotting in the circuit while safeguarding the patient from bleeding risks.
