Unlabelled: The aim of the study was to decrease the risk of ischemia and myocardial infarction (MI) in intraoperative and early postoperative period after carotid endarterectomy (CEA).
Material And Methods: 295 patients underwent CEA from 2001 till May 2005 in the Clinics of faculty surgery, Samarsky state medical university. Besides clinical investigation, patients underwent Doppler ultrasonography of brachiocephalic arteries, transcranial Doppler, brain CT (if appropriate), echocardiography, repeated ECG and intraoperative ECG monitoring.
Results: Patients were divided into 3 groups. The first group (n=78, 26.4%) did not receive any special preoperative cardiological care. Among them MI developed in 8 patients (10.2%) on the first postoperative day. The second group (n=131, 44.4%) received nitrates, desaggregants, calcium antagonists, ACE and metabolic drugs preoperatively. In this group there were 6 cases (4.6%) of MI in early postoperative period. The third group (n=86, 29.2%) received cardioselective lipophilic beta-blockers (Atenolol, Metoprolol), in addition to drugs that were given for the second group. No cases of MI in early postoperative period were registered in the third group. Differences were statistically significant (p<0.05).
Conclusion: Inclusion of beta-blockers into preoperative medical care before CEA procedure significantly decreases the risk of myocardial ischemia and infarction in early postoperative period (24 hours).

Decreasing Postanesthesia Care Unit Length of Stay for Carpal Tunnel Release Patients: A Quality Improvement Initiative.

Medical University of South Carolina, Charleston, SC. Electronic address:
Purpose: The purpose of the project was to reduce the occurrence of nonclinical delays resulting in increased postanesthesia care unit length of stay for carpal tunnel release patients in an ambulatory orthopedic surgery center through the implementation of new workflow processes in both the preoperative and postoperative phases of care.
Design: Pre-post design, with data being analyzed both before and after implementation of evidence-based quality improvement measures to assess for effectiveness of project interventions.
Methods: At the ambulatory orthopedic surgery center, preintervention data were gathered for 6 months on carpal tunnel release patients (n = 185) to determine the root causes of discharge delays (January to June 2023).
Metabolomic and Lipidomic Profiling for Pre-Transplant Assessment of Delayed Graft Function Risk Using Chemical Biopsy with Microextraction Probes.

Organ shortage remains a significant challenge in transplantology, prompting efforts to maximize the use of available organs and expand the donor pool, including through extended criteria donors (ECDs). However, ECD kidney recipients often face poorer outcomes, including a higher incidence of delayed graft function (DGF), which is linked to worse graft performance, reduced long-term survival, and an increased need for interventions like dialysis. This underscores the urgent need for strategies to improve early DGF risk assessment and optimize post-transplant management for high-risk patients.

Varicocele repair in men with non-obstructive azoospermia (NOA) remains a subject of debate due to inconsistent outcomes. This study aimed to evaluate the impact of microsurgical varicocelectomy on sperm recovery rates in men with NOA and to assess the role of varicocele grade and testicular histopathology in predicting postoperative outcomes. A retrospective cohort study was conducted of 78 men diagnosed with NOA and clinical varicocele who underwent microsurgical subinguinal varicocelectomy with simultaneous diagnostic and therapeutic testicular biopsy at the Department of Urology of the University of Ioannina between September 2013 and December 2021.

Multimodal analgesia has been shown to be effective in facilitating early postoperative gastrointestinal function and rehabilitation in patients undergoing open gastrectomy. We conducted a clinical trial to investigate the effectiveness of bilateral rectus sheath block (RSB) with continuous bupivacaine infusion in comparison with placebo following elective open gastrectomy. Patients indicated for elective open gastrectomy were screened, enrolled, and randomised between October 2021 and September 2023.
