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

open access: yesJournal 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 ...

Large Proportions of Surface Ozone and Premature Mortality Due to a Stratospheric Intrusion Event in North China

open access: yesInternational Journal of Climatology, EarlyView.
This study, by examining a typical stratospheric intrusion event that occurred in North China from 30 to 31 July 2021, found that the event led to a sharp increase in near‐surface ozone concentrations by 23 ppbv within 36 h, accounting for 40% of the total observed ozone levels, with localised peaks exceeding 30 ppbv.

Guidelines for nutrition in adults with head and neck cancer: The American Society for Parenteral and Enteral Nutrition

open access: yesJournal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Head and neck cancer represents the seventh most common cancer diagnosis globally. Maintaining sufficient nutrition is important for preventing malnutrition (undernutrition) and muscle wasting, which contribute to worse outcomes, although many patients are unable to maintain adequate oral intake throughout treatment.

Cost‐effectiveness and long‐term outcomes of periodontal regeneration versus dental implants: A retrospective study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Direct comparative data on periodontal regeneration (PR) versus extraction and implant placement remain limited. Tooth‐specific periodontal conditions such as furcation involvement and overall tooth prognosis may dictate success or failure of such treatment.
