Evaluation of basic life support interventions for foreign body airway obstructions: A population-based cohort study.

Aim: To quantify the associations of foreign body airway obstruction (FBAO) basic life support (BLS) interventions with FBAO relief and survival to discharge.

Methods: We identified prehospital FBAO patient encounters in Alberta, Canada between Jan 1, 2018 and Dec 31,2021 using the provincial emergency medical services' medical records, deterministically linked to hospital data. Two physicians reviewed encounters to determine cases and extract data.

Prediction of major postoperative events after non-cardiac surgery for people with kidney failure: derivation and internal validation of risk models.

Background: People with kidney failure often require surgery and experience worse postoperative outcomes compared to the general population, but existing risk prediction tools have excluded those with kidney failure during development or exhibit poor performance. Our objective was to derive, internally validate, and estimate the clinical utility of risk prediction models for people with kidney failure undergoing non-cardiac surgery.

Design, Setting, Participants, And Measures: This study involved derivation and internal validation of prognostic risk prediction models using a retrospective, population-based cohort.

Preferences of Patients With Chronic Kidney Disease for Invasive Versus Conservative Treatment of Acute Coronary Syndrome: A Discrete Choice Experiment.

Background Patients with chronic kidney disease (CKD) can experience acute coronary syndromes (ACS) with high morbidity and mortality. Early invasive management of ACS is recommended for most high-risk patients; however, choosing between an early invasive versus conservative management approach may be influenced by the unique risk of kidney failure for patients with CKD. Methods and Results This discrete choice experiment measured the preferences of patients with CKD for future cardiovascular events versus acute kidney injury and kidney failure following invasive heart procedures for ACS.

Using the Revised Cardiac Risk Index to Predict Major Postoperative Events for People With Kidney Failure: An External Validation and Update.

Background: People with kidney failure have high risk of postoperative morbidity and mortality. Although the revised cardiac risk index (RCRI) is used to estimate the risk of major postoperative events, it has not been validated in this population. We aimed to externally validate the RCRI and determine whether updating the model improved predictions for people with kidney failure.

Reconstructive Surgeons as Essential Operative Consultants: Quantifying the True Value of Plastic Surgeons to an Academic Medical Center.

Background: The revenue generated by plastic surgeons assisting other surgical services is poorly captured by hospital accounting systems, which categorize solely by attending physician of record. The financial impact of reconstructive surgery is thus systematically underestimated. The authors sought to quantify the overlooked value of plastic surgeons as consultants who facilitate complex and profitable operations.

Derivation and External Validation of a Risk Index for Predicting Acute Kidney Injury Requiring Kidney Replacement Therapy After Noncardiac Surgery.

Importance: Severe acute kidney injury (AKI) is a serious postoperative complication. A tool for predicting the risk of AKI requiring kidney replacement therapy (KRT) after major noncardiac surgery might assist with patient counseling and targeted use of measures to reduce this risk.

Objective: To derive and validate a predictive model for AKI requiring KRT after major noncardiac surgery.

Routine Prophylactic Endoscopic Clipping Is Not Efficacious in the Prevention of Delayed Post-Polypectomy Bleeding: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Background And Aims: Colorectal cancer (CRC) can be prevented through colonoscopic polypectomy, but this exposes patients to risks, including delayed post-polypectomy bleeding (DPPB). Endoscopists increasingly use clips prophylactically with the aim of preventing DPPB. However, clips are costly, and data to support their efficacy in this context are inconsistent.

The financial value of vascular surgeons as operative consultants to other surgical specialties.

Objective: Vascular surgeons provide assistance to other surgical specialties through planned and unplanned joint operative cases. The financial impact to the hospital of vascular surgeons as consultants in this context has yet to be quantified. We sought to quantify the financial value of services provided by consulting vascular surgeons in the performance of joint operative procedures, both planned and unplanned.

Long-term risk of cardiovascular mortality in lymphoma survivors: A systematic review and meta-analysis.

Cardiovascular disease has been identified as one of the late complications of cancer therapy. The purpose of this study was to quantify the long-term risk of cardiovascular mortality among lymphoma survivors relative to that of the general population. A systematic review and meta-analysis were conducted.

Dose-dependent interferon-gamma release in dairy calves experimentally infected with Mycobacterium avium subspecies paratuberculosis.

The interferon-gamma (IFN-γ) release assay is considered useful for diagnosis of subclinical paratuberculosis. However, interpretation can be subjective and complex; therefore, additional information regarding the course of the cellular immune response and effects of age and dose at infection would be helpful. Thirty-three calves were randomly allocated to 10 challenge groups and a negative control group.
