Identification of Cannabis Product Characteristics and Pricing on Dark Web Markets.

Growing cannabis use has made it the most widely cultivated and trafficked illicit drug globally according to the World Health Organization, with 147 million people consuming cannabis-derived products (CDPs) in various product forms and constituency. Despite restrictions in certain countries, unregulated access can still be found on the dark web which specializes in trafficking of illicit goods. The objective was to systematically collect data from multiple marketplaces to identify types of cannabis products offered for sale.

Surgical frequency analysis of patients clustered according to postoperative pain trajectory: a retrospective study.

Oropharyngeal and orthognathic surgeries cause more postoperative pain than simple dental procedures. The lack of detailed pain pattern analysis after dental surgeries makes pain management challenging. We assessed postoperative pain patterns in patients undergoing various dental surgeries, categorized based on changing pain levels, and identified the most frequent surgical procedures within each pain pattern cluster.

Videolaryngoscopy is associated with a lower rate of double-lumen endotracheal tube malposition in thoracic surgery procedures, retrospective single-center study.

Abstarct: BACKGROUND: The optimal positioned double-lumen endotracheal tubes (DLT) is crucial in thoracic surgery requiring lung isolation. This study aims to compare the accuracy and complication rates of DLT placement using videolaryngoscopy (VL) versus conventional direct laryngoscopy (DL).

Methods: This retrospective single-center study included 89 patients who underwent thoracic surgery with DLT placement between July 2023 and May 2024.

Heparin rebound in patients undergoing off-pump coronary artery bypass grafting surgery: a single-center retrospective study.

Background: Heparin, an anticoagulant used in cardiac surgery, can result in heparin rebound (HR), where it returns postoperatively despite being neutralized with protamine. This study was designed to investigate the prevalence of HR in patients undergoing off-pump coronary artery bypass grafting (OPCAB) and evaluate the impact of HR on their short-term outcomes.

Methods: HR was defined by a 10% increase in activated coagulation time (ACT) following two hours of heparin neutralization with protamine, bleeding over 200 mL/h, and abnormal laboratory coagulation examination results.

Economic impact of prolonged tracheal extubation times on operating room time overall and for subgroups of surgeons: a historical cohort study.

Background: Prolonged tracheal extubation time is defined as an interval ≥ 15 min from the end of surgery to extubation. An earlier study showed that prolonged extubations had a mean 12.4 min longer time from the end of surgery to operating room (OR) exit.

Oxygenation targets for endovascular therapy in acute ischemic stroke patients (Oxy-TARGET): protocol for a single-centre, open-label randomised controlled trial.

Introduction: Preclinical studies have shown that oxygen therapy can improve ischaemic brain tissue oxygen tension, reduce reperfusion injury after revascularisation, promote neuroregeneration and inhibit inflammatory responses potentially exerting a beneficial effect after endovascular treatment (EVT) in patients with acute ischaemic stroke (AIS). However, the optimal fraction of inspired oxygen (FiO) during EVT under general anaesthesia is currently unknown. Therefore, we are conducting a randomised controlled trial (RCT) to evaluate the impact of high-concentration oxygen vs low-concentration normobaric oxygen on early neurological function after EVT.

Altered thrombin generation with prothrombin complex concentrate is not detected by viscoelastic testing: an in vitro study.

Background: Bleeding guidelines currently recommend use of viscoelastic testing (VET) to direct haemostatic resuscitation in severe haemorrhage. However, VET-derived parameters of clot initiation, such as clotting time (CT) and activated clotting time (ACT), might not adequately reflect a clinically relevant interaction of procoagulant and anticoagulant activity, as revealed by thrombin generation assays. The aim of this study was to evaluate the ability of CT and ACT to indicate thrombin generation activity.

Inhibition of HDAC6 elicits anticancer effects on head and neck cancer cells through Sp1/SOD3/MKP1 signaling axis to downregulate ERK phosphorylation.

Oxidative stress caused by reactive oxygen species (ROS) and superoxides is linked to various cancer-related biological events. Extracellular superoxide dismutase (SOD3), an antioxidant enzyme that removes superoxides, contributes to redox homeostasis and has the potential to regulate tumorigenesis. Histone deacetylase 6 (HDAC6), a major HDAC isoform responsible for mediating the deacetylation of non-histone protein substrates, also plays a role in cancer progression.

Esketamine alleviates LPS-induced depression-like behavior by activating Nrf2-mediated anti-inflammatory response in adolescent mice.

Background: The mechanisms underlying esketamine's therapeutic effects remain elusive. The study aimed to explore the impact of single esketamine treatment on LPS-induced adolescent depressive-like behaviors and the role of Nrf2 regulated neuroinflammatory response in esketamine-produced rapid antidepressant efficacy.

Methods: Adolescent male C57BL/6J mice were randomly assigned to three groups: control, LPS, and LPS + esketamine (15 mg/kg, i.

Targeted mitochondrial function for cardiac fibrosis: An epigenetic perspective.

Mitochondria, commonly referred to as "energy factories"of cells, play a crucial role in the function and survival of cardiomyocytes. However, as research on cardiac fibrosis has advanced, mitochondrial dysfunction(including changes in energy metabolism, calcium ion imbalance, increased oxidative stress, and apoptosis)is now recognized as a significant pathophysiological pathway involved in cardiac remodeling and progression, which also negatively affects the function and structure of the heart. In recent years, research focusing on targeting mitochondria has gained significant attention, offering new approaches for treating cardiac fibrosis.

Ethylene glycol toxicosis in 39 sport horses following ingestion of contaminated water: a case report.

Ethylene glycol toxicosis is a common occurrence in dogs and cats but has been reported in other species as well. Up to date, only one case of ethylene glycol toxicosis has been described in horses, and specific guidelines for treating ethylene glycol intoxication in this species are not available. Here we describe the case of 39 sport horses that ingested water contaminated with ethylene glycol.

The impact of race, ethnicity, and socioeconomic status on early adolescent sleep disturbances for youth exposed to adverse childhood experiences.

Background: Adverse childhood experiences (ACEs) may increase the risk for adolescent sleep disturbances, though the impact of race, ethnicity, and socioeconomic status (SES) remains unclear.

Objective: We sought to determine the direct and moderating impact of race, ethnicity, family SES, and community SES on sleep disturbances across early adolescence for ACE-exposed youth.

Participants And Setting: This secondary analysis used longitudinal Adolescent Brain Cognitive Development Study® data (2016-2022) from youth who experienced ≥1 ACE by age 9-10 years.

Effectiveness of tramadol or topic lidocaine compared to epidural or opioid analgesia on postoperative analgesia in laparoscopic colorectal tumor resection.

Background: Chronic postoperative pain is the most common postoperative complication that impairs quality of life. Postoperative pain gradually develops into neuropathic pain. Multimodal analgesia targets multiple points in the pain pathway and influences the mechanisms of pain chronification.

Ethical Use of Cadaveric Images in Anatomical Textbooks, Atlases, and Journals: A Consensus Response From Authors and Editors.

Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose.

Impact of neutrophil percentage-to-albumin ratio on mortality in iron-deficiency anemia patients: a retrospective study using MIMIC-IV database.

Background: In the intensive care unit (ICU), the incidence of iron-deficiency anemia (IDA) is relatively high and is associated with various adverse clinical outcomes. Therefore, it is crucial to identify simple and practical indicators to assess the mortality risk in ICU patients with IDA. This study aims to investigate the relationship between the Neutrophil Percentage-to-Albumin Ratio (NPAR) levels in patients with IDA in the ICU and their all-cause mortality at 30 and 365 days.
