Introduction Esophageal and esophago-gastric junction (EGJ) adenocarcinomas remain a major health problem worldwide with a worryingly increasing incidence. Recent trials indicate survivals benefit for preoperative or perioperative chemoradiotherapy compared to surgery alone. Beside standard chemoradiotherapy regimens, new therapeutic approaches with targeted therapies have been proposed for the treatment of resectable disease. However, clinical outcomes remain extremely poor due to drug resistance phenomena...

OBJECTIVES: The most important treatment strategy for obstructive nephropathy is to protect renal tissue from the deleterious effects of fibrosis. Therefore, we sought to investigate the renoprotective effects of darbepoetin alfa on unilateral ureteral obstructions. METHODS: We used 12 female and 12 male 3-monthold Wistar rats weighing between 250 and 350 g. The rats were divided equally into sham, darbepoetin and control groups. With the exception of the sham group, left unilateral obstructions were applied to all of the rats...

BACKGROUND: Perioperative chemotherapy significantly improves survival in patients with locally advanced oesophagogastric cancer (EGC). However, as approximately 60% of patients will die from their disease, new therapeutic agents such as molecular-targeted drugs are needed. PATIENTS AND METHODS: To evaluate the role of panitumumab with perioperative chemotherapy, previously untreated patients with locally advanced EGC received, in an open-label randomised phase II study (NEOPECX), standard epirubicin, cisplatin, capecitabine (ECX) chemotherapy with or without panitumumab...

Neuroimaging research has demonstrated definitive involvement of the central nervous system in the development, maintenance, and experience of chronic pain. Structural and functional neuroimaging has helped elucidate central nervous system contributors to chronic pain in humans. Neuroimaging of pain has provided a tool for increasing our understanding of how pharmacologic and psychologic therapies improve chronic pain. To date, findings from neuroimaging pain research have benefitted clinical practice by providing clinicians with an educational framework to discuss the biopsychosocial nature of pain with patients...

BACKGROUND: Preoperative blood-based inflammatory biomarkers have been suggested to improve staging and prognostication in patients with upper-tract urothelial carcinoma (UTUC). Neutrophil-to-lymphocyte ratio (NLR) is the most studied blood-based biomarker. NLR is an indicator of systemic inflammation and has been shown to be associated with a poor prognosis in various malignancies. The aim of this study was to analyze the current evidence regarding the prognostic significance of preoperative NLR in patients undergoing radical nephroureterectomy (RNU) for UTUC to assess its prognostic potential...

BACKGROUND: Early detection followed by prompt intervention is essential for the treatment of periprosthetic joint infection (PJI). D-dimer, a fibrin degradation product, characteristically changes rapidly during early postoperative period and has a short half-life. The aim of this prospective study was to measure postoperative change of D-dimer level after joint arthroplasty in conjunction with ESR and CRP. METHODS: ESR, CRP, and D-dimer levels were measured on the day before surgery, postoperative days 1, 2, 3, and 5 and weeks 2 and 6 in 65 patients who underwent elective primary total hip arthroplasty (38 hips in 38 patients) or total knee arthroplasty (27 knees in 27 patients)...

BACKGROUND: The development of sensitive myocardial-specific cardiac biomarkers allows for detection of very small amounts of myocardial injury or necrosis. Myocardial injury (MI) as a prelude of the serious perioperative complication myocardial infarction, should be paid more attention, especially in elderly susceptible patients. Myocardial injury after abdominal surgery in elderly patients has not been described yet. The objectives of this study were to identify the incidence, predictors, characteristics and the impact of MI on outcome in elderly patients underwent abdominal surgery...

Background: Acute kidney injury (AKI) following cardiac surgery leads to increased morbidity and mortality. Characterization and validation of early biomarkers of AKI may ultimately facilitate early therapeutic intervention. We have previously identified that elevated urinary hepcidin-25 is inversely and independently associated with the development of AKI in adult cardiac surgery patients. Hepcidin-25 is an antimicrobial peptide that sequesters iron intracellularly, and its elevation following human ischemia reperfusion injury may represent a renoprotective response to minimize renal injury...

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...
