Background: A new surgical technique to define intra-operatively segmental and subsegmental areas of the liver using ultrasound-guided bimanual liver compression has been recently described. However, this technique does not allow disclosure of the subsegmental ventral (S8v) and dorsal (S8d) portions of segment 8 (S8). Another technique that overcomes these limitations is described.
Methods: Six patients with hepatoma, cirrhosis and no evidence of portal vein thrombosis were submitted to the procedure. Demarcation of the resection area was achieved using ultrasound-guided finger compression of the S8 subsegmental portal branches (P8v and P8d).
Results: The procedure was feasible in all patients and demarcation was always obtained within 1 min of bimanual ultrasound-guided compression. In one patient, the entire S8 was resected. In the remaining five patients, the dorsal (four patients) or the ventral (one patient) portion was removed, respectively. There was no mortality or morbidity and no blood transfusions were administered.
Conclusions: Disclosure of the subsegmental portions of S8 using the ultrasound-guided compression technique was feasible, safe and effective, and represents the completion of the ultrasound-guided compression technique for performing segmental and subsegmental anatomical resection of the liver.

Recently, 3-D porous architecture of the composites play a key role in cell proliferation, bone regeneration, and anticancer activities. The osteoinductive and osteoconductive properties of β-TCP allow for the complete repair of numerous bone defects. Herein, β-TCP was synthesized by wet chemical precipitation route, and their 3-D porous composites with HBO and Cu nanoparticles were prepared by the solid-state reaction method with improved mechanical and biological performances.

Pocket hematoma is a common and serious complication following cardiac implantable electronic device (CIED) implantation, contributing to significant morbidity and mortality. This study aimed to evaluate the efficacy of a novel pocket compression device in reducing pocket hematoma occurrence. We enrolled 242 patients undergoing CIED implantation, randomly assigning them to receive either the novel compression vest with a pressure cuff or conventional sandbag compression.

Background: Nonocclusive mesenteric ischemia (NOMI), a subtype of acute mesenteric ischemia, is primarily caused by mesenteric arterial vasoconstriction and decreased vascular resistance, leading to impaired intestinal perfusion.Commonly observed after cardiac surgery, NOMI affects older patients with cardiovascular or systemic diseases, accounting for 20-30% of acute mesenteric ischemia cases with a mortality rate of ∼50%. This review explores NOMI's pathophysiology, clinical implications in aortic dissection, and the unmet needs in diagnosis and management, emphasizing its prognostic significance.

Objective: One of the most severe endocrine side effects of immune checkpoint inhibitors (ICI) is hypophysitis leading to adrenal insufficiency. Recovery is rare, although it has been reported after high-dose glucocorticoid treatment. This is the first randomised study to evaluate whether hormonal recovery differs in patients treated with high-dose glucocorticoids versus glucocorticoid replacement therapy.

Acoustical properties are essential for understanding the molecular interactions in fluids, as they influence the physicochemical behavior of liquids and determine their suitability for diverse applications. This study investigated the acoustical parameters of silver nanoparticles (Ag NPs), reduced graphene oxide (rGO), and Ag/rGO nanocomposite nanofluids at varying concentrations. Ag NPs and Ag/rGO nanocomposites were synthesized via a Bos taurus indicus (BTI) metabolic waste-assisted method and characterized using advanced techniques, including XRD, TEM, Raman, DLS, zeta potential, and XPS.
