Accuracy of cephalometric landmark and cephalometric analysis from lateral facial photograph by using CNN-based algorithm.
Sci Rep
December 2024
Department of Orthodontics, Tokyo Dental College, 2-9-18, Kandamisaki-Cho, Chiyoda- Ku, Tokyo, 101-006, Japan.
Cephalometric analysis is the primary diagnosis method in orthodontics. In our previous study, the algorithm was developed to estimate cephalometric landmarks from lateral facial photographs of patients with normal occlusion. This study evaluates the estimation accuracy by the algorithm trained on a dataset of 2320 patients with added malocclusion patients and the analysis values.

Division of Orthodontics, University Clinics of Dental Medicine, University of Geneva, 1 rue Michel-Servet, 1205 Geneva, Switzerland.
Objectives: To evaluate whether unilateral functional posterior crossbite in growing children creates an asymmetry in masseter muscle thickness and whether this asymmetry is normalized after crossbite correction.
Materials And Methods: Two groups of growing individuals were studied prospectively: (i) a treatment group: children with unilateral functional posterior crossbite, undergoing crossbite correction with maxillary expansion; and (ii) a control group: children without transversal malocclusions and orthodontic treatment. The thickness of the masseter muscles was measured bilaterally using ultrasonographic recordings at three time points: pre-treatment (T0); 9 months after (T1); and 30 months after posterior crossbite correction (T2); and at equivalent time points in the control group.
Prognostic Relevance of Relative Ellipsoid Zone Reflectivity for Ellipsoid Zone Loss in Macular Telangiectasia Type 2.
Invest Ophthalmol Vis Sci
December 2024
Department of Ophthalmology, University of Bonn, Bonn, Germany.
Purpose: The relative ellipsoid zone reflectivity (rEZR) is an innovative biomarker for photoreceptor alterations and showed association with disease staging in macular telangiectasia type 2 (MacTel). However, its prognostic relevance for the ellipsoid zone (EZ) loss is unclear.
Methods: Longitudinal spectral-domain optical coherence tomography (SD-OCT) imaging of patients with MacTel from an observational natural history study was used for en face determination of manifest EZ loss.
Lost and found: dynamics of relationship and employment status over time in people with affective and psychotic spectrum disorders.

Department of Psychiatry and Psychotherapy, LMU University Hospital, LMU Munich, Germany.
Background: Employment and relationship are crucial for social integration. However, individuals with major psychiatric disorders often face challenges in these domains.
Aims: We investigated employment and relationship status changes among patients across the affective and psychotic spectrum - in comparison with healthy controls, examining whether diagnostic groups or functional levels influence these transitions.
Long-term associations between ambient air pollution and self-perceived health status: Results from the population-based KORA-Fit study.

Institute of Epidemiology, Helmholtz Zentrum München - German Research Center for Environmental Health, Neuherberg, Germany.
Background: Little is known about the association between air pollution and self-perceived health (including both health-related quality of life [HRQoL] and self-rated health [SRH]). The aim of this study was therefore to explore whether long-term air pollution exposure is associated with worse self-perceived health, as measured by different tools.
Methods: We used a land-use regression model to determine the annual average levels of particulate matter with a diameter <10 μm (PM), coarse particles (PM), fine particles (PM), fine particle absorbances (PM), particle number concentration (PNC), ozone (O), nitrogen dioxide (NO), and nitrogen oxide (NO) for geocoded residential addresses (2014-2015).
