A printed fringe pattern is imaged by a CCD camera, whereas a phase object is placed in the ray path for imaging. The ray deflections distort the image of the pattern and are measured by evaluation of the image with the Fourier transform method.

Circadian Misalignment Impacts Cardiac Autonomic Modulation in Adolescence.
Sleep
January 2025
Sleep Research & Treatment Center, Department of Psychiatry & Behavioral Health, Penn State University, College of Medicine, Hershey PA, USA.
Study Objectives: Although heart rate variability (HRV), a marker of cardiac autonomic modulation (CAM), is known to predict cardiovascular morbidity, the circadian timing of sleep (CTS) is also involved in autonomic modulation. We examined whether circadian misalignment is associated with blunted HRV in adolescents as a function of entrainment to school or on-breaks.
Methods: We evaluated 360 subjects from the Penn State Child Cohort (median 16y) who had at least 3-night at-home actigraphy (ACT), in-lab 9-h polysomnography (PSG) and 24-h Holter-monitoring heart rate variability (HRV) data.
DELTO Study: Delphi Consensus on Long-Term Textbook Outcome After Metabolic Bariatric Surgery.
Obes Surg
January 2025
Ziekenhuis Groep Twente, Almelo, Netherlands.
Background: This study aimed to create a comprehensive Core Outcome Set (COS) for assessing the long-term outcome (≥ 5 years) after Metabolic Bariatric Surgery (MBS), through the use of the Delphi method.
Methods: The study utilized a three-phase approach. In Phase 1, a long list of items was identified through a literature review and expert input, forming the basis for an online Delphi survey.
A New Instrument to Define Parental Fear Regarding Feeding Their Children: A Reliability and Validity Study.
Dysphagia
January 2025
Faculty of Physical Therapy and Rehabilitation, Hacettepe University, Ankara, Turkey.
This study aimed to develop the 'Fear of Feeding My Child- A Parental Report (FF-PR)', which measures the parental fear of feeding their children, and to determine its reliability and validity. The study consists of the developmental phase and reported the content validity, internal consistency, test-retest reliability, construct, criterion, and discriminant validity. The study included two groups; 'Group I (N = 90)' who had a neurological disorder and their parents, and 'Group II (N = 60)' who were typically developing children without any feeding and swallowing problems and their parents.

Anal Chem
January 2025
State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences, Wuhan 430074, PR China.
The elemental imaging of laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) provides spatial information on elements and therefore can further investigate the growth or evolution processes of an analyte. However, the accurate determination of spatial information is limited by the decoupling between the elemental distribution and mass spectrometry signals. This phenomenon, which is more distinct when high-diffusion ablation cells are used, arises from the overlap of ablation and the transport dispersion of aerosols.

J Crohns Colitis
January 2025
Division of Gastroenterology, Massachusetts General Hospital and Harvard Medical School, Boston, USA.
Background: Extraintestinal Manifestations (EIMs) of Inflammatory Bowel Disease (IBD) are frequently experienced by patients and may lead to severe symptoms and fatigue. However, the reporting patterns of these outcomes in IBD randomized controlled trials (RCTs) is not clear.
Methods: We searched placebo controlled phase 3 RCTs of advanced therapies in IBD and assessed the frequency and means of reporting EIM and fatigue data in these studies.
