BACKGROUND: Matrix Gla protein (MGP) is an extrahepatic protein that is dependent on glutamate carboxylation, a vitamin K-dependent process. Its dysfunctional form, desphospho-uncarboxylated-MGP, has been associated with increased arterial calcification and stiffness. The aim of this study was to measure the degree of postoperative carboxylation of MGP and two other Gla proteins in patients scheduled for abdominal or orthopaedic surgery. METHODS: Forty patients undergoing abdominal or orthopaedic surgery were included...

Gastric cancer is one of the most frequent malignancies worldwide. Despite improvements in diagnosis and therapy, the overall prognosis remains poor. In the last decade, several anti-angiogenic drugs for cancer treatment have been approved and lately also introduced to gastric cancer treatment. While the initial trials focused only on unresectable or metastatic cancer, anti-angiogenic treatment is now also investigated in the perioperative and neoadjuvant setting. In this review, an overview of the role of angiogenesis and angiogenic factors in gastric cancer as well as anti-angiogenic treatment of gastric cancer is provided...

Acute kidney injury is a prevalent but underdiagnosed complication that is associated with increased in-hospital morbidity and mortality. The importance of this complication is being increasingly recognized. The lack of timely diagnostic methods and effective preemptive and therapeutic strategies make its perioperative management challenging. To reduce the incidence of acute kidney injury, it is crucial to focus the resources on high-risk patients who can be identified by clinical scoring systems with a high predictive value and newly developed renal biomarkers...

BACKGROUND: Soluble signaling molecules may play an important role in malignant pathogenesis. We hypothesize that perioperative cytokine levels are associated with outcomes in patients with pancreatic adenocarcinoma (PDAC) undergoing surgical resection. METHODS: One hundered and eighteen patients with benign or malignant pancreatic disease were enrolled in a prospective study through a protocol for banking biologic samples. Peripheral blood was drawn at time of operation, and a multiplex cytokine assay was performed...

OBJECTIVE: Numerous studies in animals and humans have demonstrated that inflammatory mediators such as tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-8 play a role in cardiopulmonary bypass (CPB), which might affect surgical outcomes. Plasma mitochondrial DNA (mtDNA), a recently discovered pro-inflammatory agent, is released by cells upon insult. This study aimed to detect changes in plasma mtDNA levels at different time points after infantile CPB and explore its potential association with inflammatory mediators...

Surgical resection remains the mainstay of treatment for patients with glioma of any grade. Maximal resection of the tumour is central to achieving long-term disease control; however, the relationship between the extent of glioma resection and actual clinical benefit for the patient is predicated on the balance between cytoreduction and neurological morbidity. For the neurosurgical oncologist, the clinical rationale for undertaking increasingly extensive resections has gained traction. In parallel, novel surgical techniques and technologies have been developed that help improve patient outcomes...

PURPOSE: To determine the time point at which thrombocytopenia after TAVI procedure is an indicator of the worst prognosis, with special consideration of perioperative platelet and coagulation activation as its potential causes. METHODS: Thirty two patients (mean age 78.5±7.9years, 62% females) qualified for TAVI procedure were prospectively evaluated. Platelet counts were assessed at baseline and for the next three postoperative (POD) days. Platelet activation was evaluated by P-selectin (PS, serum, ELISA) and platelet factor 4 (PF-4, CTAD plasma), and blood coagulation activation by prothrombin fragments 1+2 (F1+2, plasma, ELISA)...

The perioperative inflammatory response is associated with outcome after complex aortic repair. Macrophage migration inhibitory factor (MIF) shows protective effects in ischemia-reperfusion (IR), but also adverse pro-inflammatory effects in acute inflammation, potentially leading to adverse outcome, which should be investigated in this trial. This prospective study enrolled 52 patients, of whom 29 (55.7%) underwent open repair (OR) and 23 (44.3%) underwent endovascular repair (ER) between 2014 and 2015. MIF serum levels were measured until 72 h post-operatively...

The high-risk surgical patient is a growing challenge to modern health care. This cohort, although comprising only 10-15% of surgical procedures, accounts for approximately 80% of postoperative deaths and suffers a high rate of postoperative morbidity. Developing robust systems to help identify and better manage this patient group should be a priority. Risk stratification has become a valuable clinical tool for shared decision-making and the development of individualized care plans. Methods for stratifying individual risk include assessment tools, measures of functional capacity and plasma biomarker assays...
