Psychometric validation of the French version of two scales measuring general (HLS-Q12) and navigational (HLS-NAV) health literacy using the Rasch model.

Background: To examine the psychometrics properties of the French version of two scales measuring general (HLS-Q12) and navigational (HLS-NAV) health literacy (HL) using validation methods based on modern psychometric test theories: a Rasch model analysis.

Methods: The data on representative samples of the French adult population came from the Health Literacy Survey (N = 2 003), conducted in France in two waves (2020 and 2021), and from the third wave of SLAVACO study (N = 2 022), conducted in December 2021. A Rasch analysis was performed using a partial credit model with marginal maximum likelihood estimation adapted to polytomous data.

The French General Population's Perception of New Information and Communication Technologies for Medical Consultations: National Survey.

Background: The development of telehealth and telemedicine, in the form of increased teleconsultation and medical telemonitoring, accelerated during the COVID-19 health crisis in France to ensure continued access to care for the population. Since these new information and communication technologies (ICTs) are diverse and likely to transform how the health care system is organized, there is a need better to understand public attitudes toward them and their relationship with peoples' current experience of health care.

Objective: This study aimed to determine the French general population's perception of the usefulness of video recording/broadcasting (VRB) and mobile Health (mHealth) apps for medical consultations in France during the COVID-19 health crisis and the factors associated with this perception.

Reperfusion therapy for acute ischemic stroke in older people: An observational real-life study.

Background: While randomized clinical trials have shown the benefit of thrombolysis and endovascular thrombectomy (EVT) in patients with acute ischemic stroke (AIS), we aimed to describe in a real-life study the differences between older (>80 years old) and younger patients treated for AIS.

Methods: Thousand patients treated with thrombolysis and/or EVT were consecutively included in a prospective monocentric database (admitted from December 2015 to May 2019 in our comprehensive stroke center). Demographic data with detailed history, baseline physical examinations and treatments, laboratory and imaging data, prestroke functional status, and outcome 3 months after stroke were analyzed.

Early Acceptability of a Mobile App for Contact Tracing During the COVID-19 Pandemic in France: National Web-Based Survey.

Background: Several countries have implemented mobile apps in an attempt to trace close contacts of patients with COVID-19 and, in turn, reduce the spread of SARS-CoV-2. However, the effectiveness of this approach depends on the adherence of a large segment of the population.

Objective: The aims of this study were to evaluate the acceptability of a COVID-19 contact tracing mobile app among the French population and to investigate the barriers to its use.

Pre-procedural predictive factors of symptomatic intracranial hemorrhage after thrombectomy in stroke.

Objective: Symptomatic intracerebral hemorrhage (sICH) is a common complication of acute ischemic stroke (AIS) associated with limited treatments and poor outcomes. We aimed to identify predictive factors of sICH in patients with AIS following mechanical thrombectomy (MT) in a real-world setting.

Methods: Patients with large vessel occlusion of the anterior circulation treated with MT were consecutively included in a prospective monocentric cohort.

Cancer information overload: Association between a brief version of the CIO scale and multiple cancer risk management behaviours.

Objectives: To demonstrate the best psychometric properties of the revised 5-item Cancer Information Overload (CIO) scale over the 10- and 8-item versions, for both English and French native speakers, and to explore the relationships between CIO and several cancer risk management behaviours in a large sample of caregivers, cancer survivors and healthy subjects.

Methods: 2809 participants (2568 from France, 241 from Australia) from two cancer survivor networks answered a self-administered questionnaire. After assessing the psychometric properties we studied the impact of CIO on health behaviours using multivariate logistic regression.

Comparison of Pressure Reactivity Index and Mean Velocity Index to Evaluate Cerebrovascular Reactivity During Induced Arterial Blood Pressure Variations in Severe Brain Injury.

Objectives: To compare the assessment of cerebral autoregulation by cerebrovascular reactivity indices based on intracranial pressure (Pressure Reactivity Index, PRx) and on transcranial Doppler (Mean Velocity Index, Mx) during controlled variations of arterial blood pressure in severe brain injury. Primary outcome was the agreement between both cerebrovascular reactivity indices measured by the Bland-and-Altman method. Secondary outcomes were the association of cerebrovascular reactivity indices with arterial blood pressure variation, and the comparison of optimal cerebral perfusion pressures determined by both indices.
