Perioperative Immunosuppressive Factors during Cancer Surgery: An Updated Review.

Surgical excision of the primary tumor represents the most frequent and curative procedure for solid malignancies. Compelling evidence suggests that, despite its beneficial effects, surgery may impair immunosurveillance by triggering an immunosuppressive inflammatory stress response and favor recurrence by stimulating minimal residual disease. In addition, many factors interfere with the immune effectors before and after cancer procedures, such as malnutrition, anemia, or subsequent transfusion.

Anesthetics and Long Term Cancer Outcomes: May Epigenetics Be the Key for Pancreatic Cancer?

Knowledge shows a divergence of results between preclinical and clinical studies regarding anesthesia and postoperative progression of cancer. While laboratory and animal data from then 2000s onwards raised much enthusiasm in this field of research leading to several clinical investigations worldwide, data from randomized trials seem to have killed off hope for many scientists. However several aspects of the actual knowledge should be reevaluated and there is space for new strategies of investigation.

Metoclopramide and Propofol to Prevent Nausea and Vomiting during Cesarean Section under Spinal Anesthesia: A Randomized, Placebo-Controlled, Double-Blind Trial.

Background: Intra-operative nausea, vomiting and retching (NVR) are frequently associated with subarachnoid anesthesia (SA) in women undergoing cesarean section (CS). In this study performed in women undergoing CS under SA with a risk factor control strategy, we compared saline (placebo), propofol, metoclopramide and both drugs to prevent NVR.

Methods: We recorded NVR events in 110 women undergoing CS who were randomized after umbilical cord clamping to receive saline (S; = 27), metoclopramide 10 mg (M; = 28), propofol 1 mg/kg/h (P; = 27) or both drugs (PM; = 28).

Recurrence Kinetics after Laparoscopic Versus Open Surgery in Colon Cancer. A Meta-Analysis.

Background: Colorectal cancer (CRC) is a leading cause of mortality worldwide and in the UK. Surgical resection is the main curative treatment modality available and using a laparoscopic vs. an open approach may have a direct influence on the inflammatory response, influencing cancer biology and potentially the recurrence kinetics by promoting cancer growth.

Drug Repurposing, an Attractive Strategy in Pancreatic Cancer Treatment: Preclinical and Clinical Updates.

Pancreatic cancer (PC) is one of the deadliest malignancies worldwide, since patients rarely display symptoms until an advanced and unresectable stage of the disease. Current chemotherapy options are unsatisfactory and there is an urgent need for more effective and less toxic drugs to improve the dismal PC therapy. Repurposing of non-oncology drugs in PC treatment represents a very promising therapeutic option and different compounds are currently being considered as candidates for repurposing in the treatment of this tumor.

How Anesthetic, Analgesic and Other Non-Surgical Techniques During Cancer Surgery Might Affect Postoperative Oncologic Outcomes: A Summary of Current State of Evidence.

The question of whether anesthetic, analgesic or other perioperative intervention during cancer resection surgery might influence long-term oncologic outcomes has generated much attention over the past 13 years. A wealth of experimental and observational clinical data have been published, but the results of prospective, randomized clinical trials are awaited. The European Union supports a pan-European network of researchers, clinicians and industry partners engaged in this question (COST Action 15204: Euro-Periscope).

Pain control with ultrasound-guided inguinal field block compared with spinal anesthesia after hernia surgery: a randomized trial.

Background: Inguinal field block (IFB) is a recommended technique for pain control after inguinal hernia repair but is also underused by surgeons. Currently, there is no decisive evidence on which technique, IFB or spinal anesthesia block (SAB), provides better pain control during the first day after hernia repair. In this study, we compared ultrasound-guided IFB performed by anesthesiologists and SAB for pain control during the first day after hernia repair.

Analysis of gene copy number variations using a method based on lab-on-a-chip technology.

Aims And Background: Copy number variations (CNVs) contribute to genome variability and their pathogenic role is becoming evident in an increasing number of human disorders. Commercial assays for routine diagnosis of CNVs are available only for a fraction of known genomic rearrangements. Thus, it is important to develop flexible and cost-effective methods that can be adapted to the detection of CNVs of interest, both in research and clinical settings.

Molecular pathology of oxidative stress in diabetic angiopathy: role of mitochondrial and cellular pathways.

Diabetes mellitus is characterized by chronic hyperglycaemia and a significant risk of developing micro- and macrovascular complications. Growing evidence suggests that increased oxidative stress, induced by several hyperglycaemia-activated pathways, is a key factor in the pathogenesis of endothelial dysfunction and vascular disease. Reactive oxidant molecules, which are produced at a high rate in the diabetic milieu, can cause oxidative damage of many cellular components and activate several pathways linked with inflammation and apoptosis.

The molecular basis of diabetic microangiopathy.

Diabetes mellitus is a chronic disease characterized by hyperglycaemia and carbohydrate, fat and protein metabolism abnormalities, all due to an impairment in insulin homeostasis and a diffuse microangiopathy most involving retina, kidney and nerves. Several mechanisms are altered at a molecular level and interplay to develop the slow but devastating clinical impairments related to microangiopathy. Polyol pathway, advanced glycation endproducts, protein kinase C, hexosamine pathway and oxidative stress are among those mechanisms.
