Dental Students’ Temporomandibular Disorder‐Related Education, Knowledge, Attitudes, and Behavior, How Do Personal Experiences Matter?

Journal of Dental Education, EarlyView.
ABSTRACT Objectives Approximately, 5%–12% of adults in the United States are estimated to have temporomandibular disorders (TMD), making it crucial that dentists are optimally trained to diagnose and treat TMD. The objectives were to assess dental students’ TMD‐related education, knowledge, attitudes, and behavior and explore if personal TMD‐related ...

Mortality after broad‐ versus narrow‐spectrum antibiotic treatment for patients with nursing and healthcare‐associated pneumonia: A nationwide retrospective cohort study

Journal of Hospital Medicine, EarlyView.
Abstract Background Nursing and healthcare‐associated pneumonia (NHCAP) is defined as pneumonia occurring in individuals with frequent healthcare contact, such as residents of care facilities or patients with impaired activities of daily living. The effectiveness of broad‐spectrum antibiotics in treating NHCAP remains unclear.

T2‐Weighted T1 Mapping and Automated Segmentation of CSF: Assessment of Solute Gradients in the Healthy Brain

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebrospinal fluid (CSF) serves as a medium for nutrient delivery and waste clearance. The T1 relaxation rate, R1, can be used to measure the concentration of intrinsic solutes and extrinsic contrast agents. Purpose To implement a method for R1 mapping and segmentation of CSF and to use this method to explore how R1 of CSF relates ...

Association Between Gas‐Free Cerebrovascular Reactivity (CVR) and Cognitive Function in Older Adults With a High Risk for Vascular Dementia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia. Cerebrovascular reactivity (CVR) is a promising biomarker for VCID. However, CVR is not commonly measured in clinical practice due to logistical difficulties in applying a hypercapnia challenge during MR imaging. Purpose To investigate whether

Pulsatility Assessment of Cerebral Perforating Arteries Using Submillimeter‐Resolution Dual‐VENC Phase‐Contrast MRI at 3T

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Dysfunction of cerebral perforating arteries is a major contributor to cerebral small vessel disease. Developing a reliable MRI technique for assessing cerebral perforating arteries on widely accessible 3T systems would be advantageous.

Non‐Subtractive Arterial Spin Labeling‐Based (NSASL) Renal Magnetic Resonance Angiography (MRA): Development and Clinical Feasibility Evaluation

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.

Clinical Validation of a Fast MRI Method to Evaluate Brain Vascular and Parenchymal Abnormalities in Sturge‐Weber Syndrome

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Sturge‐Weber syndrome (SWS) is a rare neurocutaneous disorder associated with venous capillary malformations, atrophy, and calcifications. Longitudinal imaging is limited by risks of sedation and gadolinium exposure in children.

Enhancing Study Design and Analysis of MR Imaging Markers Through Measurement Error Modeling

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Measurement error in imaging reduces statistical power and potentially biases parameter estimation, compromising study reliability. Purpose To introduce a dual data collection design (reliability and main datasets) to quantify measurement error and apply regression calibration to correct error‐prone imaging markers, thereby ...
