Propranolol and landiolol inhibit cell proliferation enhanced by noradrenaline in human lung adenocarcinoma cells.

Previous clinical data have shown that perioperative β-blocker administration can improve lung cancer prognosis, possibly by blocking autonomic nervous system responses. This study aimed to investigate the anticancer mechanisms of the β-blockers propranolol and landiolol for human lung adenocarcinoma cells treated with noradrenaline. A549 human lung adenocarcinoma cells were exposed to each of the following alone or in combination for 2 h: medium only for naïve control; noradrenaline at a dose of 10 μmol/L; propranolol at 10 nmol/L; and landiolol at 1000 nmol/L.

"Anti-cancer" effect of ketamine in comparison with MK801 on neuroglioma and lung cancer cells.

Ketamine, a N-methyl-D-aspartate (NMDA) receptor antagonist, is commonly used to induce anaesthesia during cancer surgery and relieve neuropathic and cancer pain. This study was conducted to assess whether ketamine has any inhibiting effects on neuroglioma (H4) and lung cancer cells (A549) in vitro. The cultured H4 and A549 cells were treated with ketamine and MK801 (0.

The neutrophil to lymphocyte ratio and serum albumin as predictors of acute kidney injury after coronary artery bypass grafting.

Postoperative acute kidney injury (AKI) is a highly prevalent and serious complication after cardiac surgery. The aim of this study is to identify the predictors of AKI and the cut-off values after isolated off-pump coronary artery bypass grafting (OPCAB). A total of 329 adult patients, who underwent isolated OPCAB between December 2008 and February 2021, were retrospectively analyzed.

The differential cancer growth associated with anaesthetics in a cancer xenograft model of mice: mechanisms and implications of postoperative cancer recurrence.

Anaesthetics may modify colorectal cancer cell biology which potentially affects long-term survival. This study aims to compare propofol and sevoflurane regarding with the direct anaesthetic effects on cancer malignancy and the indirect effects on host immunity in a cancer xenograft mode of mice. Cultured colon cancer cell (Caco-2) was injected subcutaneously to nude mice (day 1).

Worse ECOG-PS Is Associated with Increased 30-Day Mortality among Adults Older than 90 Years Undergoing Non-Cardiac Surgery: A Single-Center Retrospective Study.

Background: A growing number of older patients are undergoing surgeries. However, reliable preoperative predictors of surgical mortality among older patients have not been identified. This study compared predictive factors for 30-day survival in patients older than 90 years after non-cardiac surgery.

Lung but not brain cancer cell malignancy inhibited by commonly used anesthetic propofol during surgery: Implication of reducing cancer recurrence risk.

Introduction: Intravenous anesthesia with propofol was reported to improve cancer surgical outcomes when compared with inhalational anesthesia. However, the underlying molecular mechanisms largely remain unknown.

Objectives: The anti-tumor effects of propofol and the possible underlying mechanism including altered metabolic and signaling pathways were studied in the current study.

Inhalational Anesthetics Inhibit Neuroglioma Cell Proliferation and Migration via miR-138, -210 and -335.

Inhalational anesthetics was previously reported to suppress glioma cell malignancy but underlying mechanisms remain unclear. The present study aims to investigate the effects of sevoflurane and desflurane on glioma cell malignancy changes via microRNA (miRNA) modulation. The cultured H4 cells were exposed to 3.

Anesthetics may modulate cancer surgical outcome: a possible role of miRNAs regulation.

Background: microRNAs (miRNAs) are single-stranded and noncoding RNA molecules that control post-transcriptional gene regulation. miRNAs can be tumor suppressors or oncogenes through various mechanism including cancer cell biology, cell-to-cell communication, and anti-cancer immunity.

Main Body: Anesthetics can affect cell biology through miRNA-mediated regulation of messenger RNA (mRNA).

Sevoflurane and Desflurane Exposure Enhanced Cell Proliferation and Migration in Ovarian Cancer Cells via miR-210 and miR-138 Downregulation.

Inhalational anaesthetics were previously reported to promote ovarian cancer malignancy, but underlying mechanisms remain unclear. The present study aims to investigate the role of sevoflurane- or desflurane-induced microRNA (miRNA) changes on ovarian cancer cell behaviour. The cultured SKOV3 cells were exposed to 3.

Inflammation Triggered by SARS-CoV-2 and ACE2 Augment Drives Multiple Organ Failure of Severe COVID-19: Molecular Mechanisms and Implications.

The widespread occurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to a pandemic of coronavirus disease 2019 (COVID-19). The S spike protein of SARS-CoV-2 binds with angiotensin-converting enzyme 2 (ACE2) as a functional "receptor" and then enters into host cells to replicate and damage host cells and organs. ACE2 plays a pivotal role in the inflammation, and its downregulation may aggravate COVID-19 via the renin-angiotensin system, including by promoting pathological changes in lung injury and involving inflammatory responses.

Anesthetic Considerations of Intraoperative Neuromonitoring in Thyroidectomy.

Background: Intraoperative neuromonitoring (IONM) might reduce the incidence of injury to the recurrent laryngeal nerve (RLN) during thyroidectomy. Although dislocation of endotracheal tube surface electrodes can lead to false-positive IONM results (loss of signal), the risk factors for dislocation and the effects of muscle relaxants are unclear. Therefore, to identify factors that affect IONM results, we examined the frequency and risk factors for tube dislocation after cervical extension before surgery, the effect of sugammadex administration, and the correlation between IONM results and postoperative RLN palsy.

Effect of Perioperative Lidocaine, Propofol and Steroids on Pulmonary Metastasis in a Murine Model of Breast Cancer Surgery.

Addressing the hypothesis that anaesthetic-analgesic technique during cancer surgery might influence recurrence or metastatic spread is a research priority. Propofol, which has anti-inflammatory properties in vitro, is clinically associated with reduced risk of cancer recurrence compared with sevoflurane anaesthesia in retrospective studies. Amide local anaesthetics, such as lidocaine, have cancer inhibiting effects in vitro.

Effect of Perioperative Lidocaine and Cisplatin on Metastasis in a Murine Model of Breast Cancer Surgery.

Background/aim: Mortality from breast cancer is usually attributable to metastasis. In vitro data suggest that amide local anaesthetics, e.g.

Volatile anaesthetics enhance the metastasis related cellular signalling including CXCR2 of ovarian cancer cells.

The majority of ovarian cancer patients relapse after surgical resection. Evidence is accumulating regarding the role of surgery in disseminating cancer cells; in particular anaesthesia may have an impact on cancer re-occurrence. Here, we have investigated the metastatic potential of volatile anaesthetics isoflurane, sevoflurane and desflurane on ovarian cancer cells.

Anesthesia, surgical stress, and "long-term" outcomes.

An increasing body of evidence shows that the choice of anesthetic can strongly influence more than simply the quality of anesthesia. Regional and general anesthesia have often been compared to ascertain whether one provides benefits through dampening the stress response or harms by accelerating cancer progression. Regional anesthesia offers considerable advantages, by suppressing cortisol and catecholamine levels and reducing muscle breakdown postoperatively.

Hypoxia-inducible factor-1: a possible link between inhalational anesthetics and tumor progression?

Cancer remains one of the major causes of death worldwide, and the global burden of the disease is rising continuously. Clinical retrospective data suggested that inhalational anesthetics might affect the prognosis of cancer patients, but the underlying molecular mechanism remained unknown. Hypoxia-inducible factor-1 (HIF-1) is a dimeric transcription factor and mediates various cellular responses to hypoxia, including metabolism, cell death and survival, angiogenesis, oxygen delivery, immune evasion, and genomic adaptation.
