Intravenous lidocaine improves postoperative cognition in patients undergoing laparoscopic colorectal surgery: a randomized, double-blind, controlled study.

Background: The risk of postoperative cognitive dysfunction(POCD) in laparoscopic surgery should not be overlooked. Intravenous lidocaine can reduce perioperative inflammatory response in patients undergoing laparoscopic surgery, while the effect of intraoperative intravenous lidocaine on postoperative cognitive function in patients undergoing laparoscopic colorectal cancer surgery has not been well studied. We investigated whether intraoperative lidocaine improves postoperative cognitive function after laparoscopic radical resection for colorectal cancer.

Effect of sulfide on the nitrogen removal performance and microbial community of low-substrate Anammox process.

Anammox is one of the most innovative nitrogen removal technologies, while its functional bacteria-anaerobic ammonia-oxidizing bacteria (AAOB) is sensitive to the impurities in the wastewater. In this study, the long-term effects of sulfide at different concentrations (0, 5, 10, 20, 30, 50, 25 mg L) on low substrate Anammox process were studied. The results showed that when the sulfide was 25-30 mg L, AAOB was well coupled with sulfide-denitrifying bacteria and the total nitrogen removal efficiency (TNRE) reached a maximum of 91.

A meta-analysis of the association between preoperative magnetic resonance imaging and surgical outcomes in newly diagnosed breast cancer.

Introduction: The use of preoperative magnetic resonance imaging (MRI) in newly diagnosed breast cancer has been increasing. However, the value of MRI applied to women with newly diagnosed breast cancer remains controversial. Therefore, this study focused on the association between preoperative MRI and surgical outcomes, which include mastectomy rate, breast conservation rate, and re-excision rate.

Cyclin-dependent kinase 4/6 inhibitor in combination with endocrine therapy versus endocrine therapy only for advanced breast cancer: a systematic review and meta-analysis.

Background: The resistance to endocrine therapy poses a significant challenge to the management of advanced breast cancer with hormone receptor (HR) positive and human epidermal growth factor receptor 2 (Her-2) negative. The purpose of this study was to further examine the efficacy and safety of cyclin-dependent kinase 4/6 inhibitors (CDK4/6Is) in combination with endocrine therapy as a recovery treatment for advanced breast cancer patients.

Methods: The risk of bias for each included study was assessed using the Cochrane Risk of Bias Tool.

Preoperative Antihypertensive Medication in Relation to Postoperative Atrial Fibrillation in Patients Undergoing Cardiac Surgery: A Meta-Analysis.

. We undertake a systematic review and meta-analysis to evaluate the effect of preoperative hypertension and preoperative antihypertensive medication to postoperative atrial fibrillation (POAF) in patients undergoing cardiac surgery. .

Comparison of Postoperative Events between Spinal Anesthesia and General Anesthesia in Laparoscopic Cholecystectomy: A Systemic Review and Meta-Analysis of Randomized Controlled Trials.

Background. Laparoscopic cholecystectomy is usually carried out under general anesthesia. There were a few studies which have found spinal anesthesia as a safe alternative.
