Development and validation of an EHR-based risk prediction model for geriatric patients undergoing urgent and emergency surgery.

Background: Clinical determination of patients at high risk of poor surgical outcomes is complex and may be supported by clinical tools to summarize the patient's own personalized electronic health record (EHR) history and vitals data through predictive risk models. Since prior models were not readily available for EHR-integration, our objective was to develop and validate a risk stratification tool, named the Assessment of Geriatric Emergency Surgery (AGES) score, predicting risk of 30-day major postoperative complications in geriatric patients under consideration for urgent and emergency surgery using pre-surgical existing electronic health record (EHR) data.

Methods: Patients 65-years and older undergoing urgent or emergency non-cardiac surgery within 21 hospitals 2017-2021 were used to develop the model (randomly split: 80% training, 20% test).

Simultaneous transcatheter aortic valve implantation and femoral osteosynthesis: a case report.

Background: Simultaneous cardiac and non-cardiac surgeries can be beneficial for patients, but there are still few reports on this approach.

Case Presentation: A 90-year-old woman was diagnosed with a femoral trochanteric fracture and severe aortic stenosis. A heart team conference decided to perform transcatheter aortic valve implantation (TAVI) and femoral osteosynthesis under general anesthesia on the same day.

Distinct relative abundances in pathogens detected in mechanically ventilated patients with suspected pneumonia in the intensive care unit at King Abdulaziz University Hospital.

In this study, we present for the first time the landscape of the lung microbiota in patients with ventilator-associated pneumonia in Intensive Care Units in Saudi Arabia. DNA from 83 deep endotracheal aspirate lung samples was subjected to PacBio sequencing to identify pathogens in comparison with conventional diagnostic techniques. Patients on ventilation with pneumonia presented with similar lung flora to those of patients on ventilation without pneumonia.

Preoperative Cardiac Assessment for Coronary Artery Disease: From Symptoms to Angiography.

Although cardiovascular anesthesiologists play a role in the multidisciplinary heart team, they are generally not involved prior to the diagnosis of coronary artery disease. This work was designed to broadly cover the factors influencing decision-making when proceeding with coronary angiography in a patient with suspected coronary artery disease. The authors cover the principles, rationale, benefits, and downsides of common tests involved.

Practice Advisory for Postoperative Pain Management of Thoracic Surgical Patients: Executive Summary: A Report by Society of Cardiovascular Anesthesiologists.

Patients after thoracic surgery experience significant pain that can disrupt normal respiratory mechanics, increase the risk of respiratory complications, and impair recovery. Poorly controlled postoperative pain can develop into persistent postoperative pain. In addition, using opioids for pain control in the thoracic surgical population makes them more susceptible to opioid-related side effects due to their pre-existing comorbidities.

Pain in adults with cystic fibrosis - Are we painfully unaware?

Background: A previous Australia-wide pilot study identified pain as a significant burden in people with CF (pwCF). However, the prevalence, frequency and severity have not been evaluated using validated tools.

Methods: Australian adults, pwCF and healthy controls (HC) were invited to complete an online questionnaire from July 2023 - February 2024, consisting of four validated tools: Brief Pain Inventory, Pain Catastrophising Scale, PAGI-SYM and PAC-SYM.

Faculty Perceptions on the Roles of Mentoring, Advising, and Coaching in an Anesthesiology Residency Program: Mixed Methods Study.

Background: Mentoring, advising, and coaching are essential components of resident education and professional development. Despite their importance, there is limited literature exploring how anesthesiology faculty perceive these practices and their role in supporting residents.

Objective: This study aims to investigate anesthesiology faculty perspectives on the significance, implantation strategies, and challenges associated with mentorship, advising, and coaching in resident education.

JAK/STAT3 signaling promotes pain and depression-like behaviors in rats with bone cancer pain by regulating Th17 cell differentiation.

Background: Pain and depression are common complications in patients with advanced cancer, which significantly affects their quality of life and survival. Dysregulation of the JAK/STAT3 pathway in the central nervous system is associated with pain and brain inflammatory disorders, but its role in bone cancer pain (BCP) remains unclear. This study aimed to investigate the specific role of the JAK/STAT3 pathway in the amygdala in BCP.

Intraoperative electrophysiological balloon test occlusion (BTO): A novel Solution to an inconclusive conventional BTO.

Parent Artery Occlusion (PAO) is a valid treatment choice in giant internal carotid artery (ICA) aneurysms of the cavernous segment when the preoperative balloon test occlusion (BTO) demonstrates an adequate cross circulation from the contralateral side. A high flow arterial bypass is, however, mandatory if the result suggests otherwise or is indeterminate. We present here a case of a 72-year lady where the BTO results were inconclusive.

The Receptor for Advanced Glycation End-products in the Mouse Anterior Cingulate Cortex is Involved in Neuron‒Astrocyte Coupling in Chronic Inflammatory Pain and Anxiety Comorbidity.

Previous studies have shown that astrocyte activation in the anterior cingulate cortex (ACC), accompanied by upregulation of the astrocyte marker S100 calcium binding protein B (S100B), contributes to comorbid anxiety in chronic inflammatory pain (CIP), but the exact downstream mechanism is still being explored. The receptor for advanced glycation end-products (RAGE) plays an important role in chronic pain and psychosis by recognizing ligands, including S100B. Therefore, we speculate that RAGE may be involved in astrocyte regulation of the comorbidity between CIP and anxiety by recognizing S100B.
