A Computational Fluid Dynamics Approach for Personalized Stroke Risk Assessment in Atrial Fibrillation.

Atrial fibrillation increases the risk of cerebrovascular events, being responsible of 15-18% of all strokes. The morphological and functional remodelling of the left atrium caused by atrial fibrillation favours blood stasis and, consequently, stroke risk. Several studies suggest that haemodynamic information on the left atrium and the left atrial appendage may help to better characterize stroke risk. The aim of this study was to develop a personalized computational fluid dynamics model of the left atrium w...

Functional relevance of Computational Fluid Dynamics in the field of nasal obstruction: a literature review.

Nasal airway obstruction (nasal obstruction) is a common symptom affecting the quality of life of patients. It can be estimated by patient perception or physical measurements. Computational fluid dynamics (CFD) can be used to analyze nasal ventilation modalities. There is a lack of comparative studies investigating the correlations between CFD variables and patient perception or physical measurements.

Correlations between Computational Fluid Dynamics and clinical evaluation of nasal airway obstruction due to septal deviation: an observational study.

The primary objective of this study was to determine how Computational Fluid Dynamics (CFD) could be correlated to clinical evaluation of Nasal Airway Obstruction (NAO) in a population of patients with symptomatic septal deviation (SD). The secondary objective was to determine whether CFD could define which side was the more obstructed.

Computational fluid dynamics analysis of surgical approaches to bilateral vocal fold immobility.

Bilateral vocal fold immobility (BVFI) is a rare and life-threatening condition in which both vocal folds are fixed, resulting in airway obstruction associated with life-threatening respiratory compromise. Treatment of BVFI is largely surgical and remains an unsatisfactory compromise between voice, breathing, and swallowing. No comparisons between currently employed techniques currently exist. We sought to employ computational fluid dynamics (CFD) modeling to delineate the optimal surgical approach for BVFI...

Risk Estimation, Anxiety and Breast Cancer Worry in Women at Risk for Breast Cancer: A Single-Arm Trial of Personalized Risk Communication.

Elevated anxiety and breast cancer worry can impede mammographic screening and early breast cancer detection. Genetic advances and risk models make personalized breast cancer risk assessment and communication feasible, but it is unknown whether such communication of risk affects anxiety and disease-specific worry. We studied the effect of a personalized breast cancer screening intervention on risk perception, anxiety and breast cancer worry.

Computational fluid dynamics simulation to compare large volume irrigation and continuous spraying during nasal irrigation.

Nasal irrigation is now widely recognized as a treatment for chronic rhinosinusitis and during the postoperative period. However, there are no guidelines for performing irrigation. This study used computational fluid dynamics (CFD) simulation objective physical parameters to optimize and increase the efficiency of nasal irrigation and to compare large-volume, manual, and gravity pressure irrigation vs small-volume continuous spraying.

An update on risk assessment for familial and hereditary colorectal cancer.

Family history risk assessment can identify individuals at increased risk of colorectal cancer (CRC) who would benefit from earlier or more frequent CRC screening. Clinicians should evaluate the patient's family history as well as personal history to identify red flags and patterns that may suggest predisposition to CRC and then use that information to stratify risk into average, increased, and high risk categories to inform genetic counseling recommendations and personalized management.

Plasma total-tau as a biomarker of stroke risk in the community.

Higher plasma total-tau level is associated with incident dementia but its relationship with stroke risk is unknown. In this prospective community-based study, we evaluated plasma total-tau level as a biomarker of stroke risk in 2794 Framingham Heart Study participants. Persons with plasma total-tau levels in the top quintile, versus the bottom four, had an increased risk of incident stroke over a mean follow-up of 8.3 years (Hazard Ratio, 2.01; 95% Confidence Interval, 1.32-3.08) following adjustments for ...

A personalized approach to treatment with patients being matched to the best-fit treatment has been proposed as one possible solution to the currently modest treatment response rates for adolescent depression. Personalized treatment involves identifying and characterizing subgroups likely to respond differently to different treatments. We investigated the feasibility of this approach, by focusing on two key risk factors that are the purported treatment targets of cognitive behavioral therapy (CBT) and inter...

SURF (stroke with underlying risk of atrial fibrillation): Proposals for a definition.

Diagnosis of occult atrial fibrillation (AF) in stroke patients remains challenging. Several scores predictive of occult AF in stroke patients have been proposed, all based on the positive predictive value of clinical, biological, and radiological parameters, but they failed to modify the management of AF detection after stroke. The aim of this study was to identify a group of Stroke patients with Underlying Risk of Atrial Fibrillation (SURF) excluding stroke patients with low risk of AF.
