Development of a Clinical Risk Score to Risk Stratify for a Serious Cause of Vertigo in Patients Presenting to the Emergency Department.

Study Objective: Identify high-risk clinical characteristics for a serious cause of vertigo in patients presenting to the emergency department (ED).

Methods: Multicentre prospective cohort study over 3 years at three university-affiliated tertiary care EDs. Participants were patients presenting with vertigo, dizziness or imbalance.

Circulating Blood Biomarkers and Risk of Venous Thromboembolism in Cancer Patients: A Systematic Review and Meta-Analysis.

Background:  Cancer patients have an increased risk of venous thromboembolism (VTE). Currently, the availability of highly discriminatory prediction models for VTE in cancer patients is limited. The implementation of biomarkers in prediction models might lead to refined VTE risk prediction.

Benefits of First Pass Recanalization in Basilar Strokes Based on Initial Clinical Severity.

Purpose: Randomized trials demonstrating the benefits of thrombectomy for basilar artery occlusions have enrolled an insufficient number of patients with a National Institutes for Health Stroke Scale (NIHSS) score < 10 and shown discrepant results for patients with an NIHSS > 20. Achieving a first pass recanalization (FPR) improves clinical outcomes in stroke. We aimed to evaluate the effect of the FPR on outcomes among basilar artery occlusion patients, characterized by prethrombectomy initial NIHSS score.

Inherited thrombophilia gene mutations and risk of venous thromboembolism in patients with cancer: A systematic review and meta-analysis.

In the general population, individuals with an inherited thrombophilia have a higher risk of thrombosis, but the effect of inherited thrombophilia on the risk of cancer-associated venous thromboembolism (VTE) remains controversial. Our objective was to determine the risk of VTE in cancer patients with inherited thrombophilia. We conducted a systematic review and meta-analysis of studies reporting on VTE after a cancer diagnosis in adult patients who were tested for inherited thrombophilia.

Dual Antiplatelet Therapy in Minor Stroke/Transient Ischemic Attack - An Updated Network Meta-Analysis.

We previously analyzed five trials on ticagrelor/aspirin versus clopidogrel/aspirin in patients with minor stroke/ TIA in a network meta-analysis. We updated our search and identified 311 new citations with one study for inclusion: CHANCE2 enrolled patients with CYP2C19 loss-of-function alleles and randomized them to ticagrelor/aspirin or clopidogrel/aspirin. Pooling of CHANCE2 with the original studies could not be completed due to violation of NMA assumptions, due to significant inconsistency.

Thrombophilia gene mutations predict venous thromboembolism in ambulatory cancer patients receiving chemotherapy.

Background: Inherited thrombophilia and cancer both independently increase the risk of venous thromboembolism (VTE). However, whether the increased VTE risk associated with inherited thrombophilia exists in cancer patients is less clear.

Objectives: Our objective was to determine the influence of inherited thrombophilia on VTE and bleeding risk in moderate-to-high-risk ambulatory cancer patients receiving chemotherapy.

Effect modification of age and hypertension on cancer and prevalence of self-reported stroke - A cross-sectional study.

The objective of this study was to examine the effect modification of age on the relationship between cancer and prevalence of self-reported stroke. We used cross-sectional data from the 2015-2016 iteration of the Canadian Community Health Survey. A multivariable logistic regression model was used to assess the association between cancer and self-reported stroke.

Pharmacologic Interventions to Prevent Delirium in Trauma Patients: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials.

Unlabelled: To compare the relative efficacy of pharmacologic interventions in the prevention of delirium in ICU trauma patients.

Data Sources: We searched Medical Literature Analysis and Retrieval System Online, Embase, and Cochrane Registry of Clinical Trials from database inception until June 7, 2022. We included randomized controlled trials comparing pharmacologic interventions in critically ill trauma patients.

Incidence of stroke in the first year after diagnosis of cancer-A systematic review and meta-analysis.

Background: Patients newly diagnosed with cancer represent a population at highest risk for stroke. The objective of this systematic review and meta-analysis was to estimate the incidence of stroke in the first year following a new diagnosis of cancer.

Methods: We searched MEDLINE and EMBASE from January 1980 to June 2021 for observational studies that enrolled adults with a new diagnosis of all cancers excluding non-melanoma skin cancer, and that reported the incidence of stroke at 1 year.

Growth Differentiation Factor-15, High-Sensitivity Cardiac Troponin T, and N-Terminal pro-B-type Natriuretic Peptide for Predicting Risk of Venous Thromboembolism in Ambulatory Cancer Patients Receiving Chemotherapy.

Growth differentiation factor-15 (GDF-15), high-sensitivity cardiac troponin T (hs-TnT), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) are associated with increased risk of venous thromboembolism (VTE) in noncancer patients. However, the performance of these biomarkers in cancer patients is unknown. Our objective was to assess performance of these biomarkers in predicting VTE in cancer patients at intermediate to high risk for VTE (Khorana Score ≥ 2).

Comparison of Ticagrelor vs Clopidogrel in Addition to Aspirin in Patients With Minor Ischemic Stroke and Transient Ischemic Attack: A Network Meta-analysis.

Importance: Dual antiplatelet therapy (DAPT) with clopidogrel and aspirin is effective in preventing recurrent strokes after minor ischemic stroke or transient ischemic attack (TIA). However, there is emerging evidence for the use of ticagrelor and aspirin, and the 2 DAPT regimens have not been compared directly.

Objective: To compare ticagrelor and aspirin with clopidogrel and aspirin in patients with acute minor ischemic stroke or TIA in the prevention of recurrent strokes or death.

Life dissatisfaction in Canadians aged 40 and above with cancer and mental health disorders: A cross-sectional study using the Canadian Community Health Survey.

Background: Life dissatisfaction varies with different factors--particularly in the presence of chronic conditions, such as cancer. The combination of cancer and mental health disorders may increase life dissatisfaction due to lowered resilience against stress. We sought to determine if life dissatisfaction is higher in Canadians aged 40 and above with cancer compared to the cancer-free population and if there is a synergistic effect between cancer and mental health disorder on life dissatisfaction.

Incidence of stroke in the first year after diagnosis of cancer-A protocol for systematic review and meta-analysis.

Introduction: There is an increased risk of stroke in patients with cancer-this risk is particularly heightened around the time of cancer diagnosis, although no studies have systematically quantified this risk in the literature. Patients newly diagnosed with cancer without prior stroke represent a highly susceptible population in whom there is a window of opportunity to study and implement primary prevention strategies. Therefore, the objective of this systematic review and meta-analysis is to identify the cumulative incidence of ischemic and hemorrhagic strokes during the first year after a diagnosis of cancer.

Ticagrelor vs Clopidogrel in addition to Aspirin in minor ischemic stroke/ transient ischemic attack-Protocol for a systematic review and network meta-analysis.

Introduction: Patients with minor ischemic stroke or transient ischemic attack represent a high-risk population for recurrent stroke. No direct comparison exists comparing dual antiplatelet therapy regimens-namely, Ticagrelor and Aspirin versus Clopidogrel and Aspirin. This systematic review and network meta-analysis (NMA) will examine the efficacy of these two different antiplatelet regimens in preventing recurrent stroke and mortality up to 30 days.

Reversal of cocaine-induced planarian behavior by parthenolide and related sesquiterpene lactones.

Here we report the prevention and reversal of cocaine-induced behaviors in planarian worms by parthenolide and two related cyclic sesquiterpene lactones (SL), costunolide and santonin. Using established protocols, we studied two cocaine-induced behavioral effects in planaria; the induction of motility decrease and the induction of C-like hyperkinesia. Cocaine, parthenolide, costunolide, santonin, and a lactone-less cyclic sesquiterpene, beta-eudesmol, decreased planarian motility in a concentration-dependent manner.

Formation and fate of haloacetic acids (HAAs) within the water treatment plant.

Most research on the occurrence of chlorinated disinfection by-products (DBPs) in drinking water has focused on trihalomethane (THM) formation and evolution, in particular within distribution systems. In this research, we investigated the variability of the occurrence of haloacetic acids (HAAs) during the treatment process in two facilities where surface water is pre-chlorinated before being treated by conventional physico-chemical processes. The investigation focused on both seasonal and point-to-point fluctuations of HAAs.

[Nursing practice in family medicine groups and its interdisciplinary context].

Nursing practice in family medicine groups (FMGs) is a major issue in the implementation of this new healthcare organization model in Quebec. Using a constructivist qualitative research approach, a case study of a FMG in a region of Quebec looked at how the partners involved in the project defined nursing practice, and highlighted the similarities and differences in their views. The results of this study show that nursing practice as a concept is perceived in two different ways: independent practice, associated with the recognition of nurses' potential, and interdisciplinary collaborative practice.
