Article Synopsis
  • Inflammation and oxidative stress contribute significantly to lung injury caused by cardiac ischemia, and CBD shows potential in protecting lung tissue through its antioxidant and anti-inflammatory properties.
  • The study involved 40 male rats divided into four groups, where researchers induced cardiac ischemia and subsequently analyzed lung tissues for various stress and injury indicators.
  • Results indicated significant lung damage in the ischemia group, but both preventive (p-CBD) and therapeutic (t-CBD) treatments with CBD effectively mitigated this damage, restoring normal levels in various tests.

Purpose: To investigate and implement semiautomated screening for meta-analyses (MA) in urology under consideration of class imbalance.

Methods: Machine learning algorithms were trained on data from three MA with detailed information of the screening process. Different methods to account for class imbalance (Sampling (up- and downsampling, weighting and cost-sensitive learning), thresholding) were implemented in different machine learning (ML) algorithms (Random Forest, Logistic Regression with Elastic Net Regularization, Support Vector Machines).

Unlabelled: The main tools used by an orthopaedic surgeon for managing distal radial fracture treatment are recent literature and treatment guidelines. The aim of the present study was to find which factors within the study design influence study outcomes the most. Trials in three major databases (PubMed, Scopus, Embase) comparing surgical and non-surgical treatment options for adolescent and adult distal radial fractures with their original data, between 2013 and 2021, were included.

Objectives: To evaluate the long-term efficacy of a surgeon-tailored single-incision mini-sling procedure (SIMS) for the surgical treatment of stress urinary incontinence (SUI) in terms of objective cure rates, quality of life, and cost-effectiveness.

Study Design: This retrospective study included 93 women with pure SUI who underwent surgeon-tailored SIMS. All patients were evaluated with a stress cough test and quality of life questionnaire (Incontinence Impact Questionnaire [IIQ-7]) at 1 month, 6 months, 1 year, and last follow-up visit (4-7 years).

Uterine manipulation is essential for moving the uterus and proper anatomical dissection without complications during total laparoscopic hysterectomy (TLH). Although many different uterine manipulators (UM) have been designed in the last few decades, there is still no "optimal UM" that is universally safe, efficient, and cost-effective. This study aimed to compare myoma screw (MS) and UM with regard to surgical outcomes and cost-effectiveness in patients who underwent TLH.

Background: To compare the surgical outcomes and costs of in-bag abdominal manual morcellation (AMM) and contained power morcellation (PM) in laparoscopic myomectomy.

Methods: A total of 61 patients were divided into two groups based on their myomectomy specimen extraction methods: AMM group (n = 33) and electromechanical contained PM group (n = 28). The surgical outcomes and cost were compared between groups.

Context: Multiple randomized controlled trials (RCTs) on the three approaches of radical cystectomy (robotic assisted [RARC], laparoscopic [LRC], and open [ORC]) have been published recently.

Objective: To perform a systematic review and network meta-analysis (NMA) of RCTs comparing RARC, LRC, and ORC, with the primary outcomes being overall survival (OS) and recurrence-free survival (RFS).

Evidence Acquisition: A search of the Cochrane Central Register of Controlled Trials, MEDLINE, and Web of Science (last search: 20/05/2022) was performed.

Introduction: The objective of this study is to compare the effects of conventional monopolar electrosurgery (CMES) and low-thermal plasma kinetic cautery (PKC) on complications such as bleeding, abnormal wound healing, pain, and drainage in patients who underwent on-pump coronary artery bypass grafting (CABG).

Methods: This retrospective clinical study included 258 patients undergoing CABG; the patients were randomized to PKC (PEAK PlasmaBlade, n=153) and CMES (n=105) groups. The patients' clinical data were examined retrospectively for biochemical variables, postoperative drainage, post-surgery erythrocyte suspension transfusion count, surgical site pain examined with visual analogue scale (VAS), and wound healing.

Technological advances in molecular profiling have enabled the comprehensive identification of common regions of gene amplification on chromosomes (amplicons) in muscle invasive bladder cancer (MIBC). One such region is 8q22.2, which is largely unexplored in MIBC and could harbor genes with potential for outcome prediction or targeted therapy.

Background: New-onset postoperative atrial fibrillation (POAF) is the most common arrhythmia following coronary artery bypass graft surgery (CABG) and is associated with prolonged hospitalization, stroke, and mortality. The frontal plane QRS-T [f(QRS-T)] angle, which is defined as the angle between the directions of ventricular depolarization (QRS-axis) and repolarization (T-axis), is a novel marker of ventricular repolarization heterogeneity. The f(QRS-T) angle is associated with adverse cardiac outcomes.

Background: Motorized articulating laparoscopic instruments (ALI) offer more degrees of freedom than conventional laparoscopic instruments (CLI). However, a difficult learning curve and complex instrument handling are still a problem of ALI. We compared the performance of new prototypes of motorized ALI with CLI in a series of standardized laparoscopic tasks performed by laparoscopic novices.

Introduction: Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic stroke and increased mortality. The CHA2DS2-VASc score is used to estimate thromboembolic risk in AF.

Purpose: Superficial venous insufficiency is a common problem associated with varicose veins. In addition to classical symptoms, it may result in skin changes, venous ulcers and has a great impact on patients' health-related quality of life. In the last decade, minimally invasive techniques such as endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) have been developed as alternatives to surgery in an attempt to reduce morbidity and improve efficiency.

Objective: To examine the effects of classical technique, electrocautery, and ultrasonic dissection on endothelial integrity, function, and preparation time for harvesting the radial artery (RA) during coronary artery bypass grafting (CABG).

Methods: Forty-five patients who underwent isolated CABG and whose RA was suitable for use were studied and divided into three groups: Group 1, classical method (using sharp dissection); Group 2, electrocautery; and Group 3, ultrasonic cautery. Levels of prostacyclin and nitric oxide derivatives were examined biochemically; vascular cell adhesion molecule 1 (VCAM-1) and endothelial nitric oxide synthetase (eNOS) values were assessed using immunohistochemical staining.
