The paper presents the influence of impression methods, polymer materials, and implant angulation on the accuracy of the definitive working model for the production of implant-supported dental restorations, based on the analysis of results obtained using different impression methods, materials, and parallel and angulated implants. The study findings indicate that all aforementioned factors impact the accuracy of the definitive working model. Specifically, 20° implant angulation in relation to the vertical plane has a greater impact on the impression accuracy compared to parallel implants. The open and splint method in combination with addition silicone, as well as the splint method and polyether combination yielded more accurate results when using implants under 20° angulation compared to other method and material combinations. The splint method in combination with addition silicone resulted in the smallest mean deviations from the center of the parallel implant base compared to other combinations of methods and materials. Analysis results further revealed statistically significant differences in the measured indicators across impression methods, implants, and polymer materials.

Purpose: This study aimed to compare different treatment modalities to correct ill-fitted maxillary complete denture either by the conventional relining method or by scanning the relining impression and digitally construct a new denture regarding patient satisfaction, denture retention, and adaptation.

Materials And Methods: Twelve edentulous patients suffering from loose maxillary complete dentures were selected, dentures' borders and fitting surfaces were prepared, and relining impressions were taken, the impressions were scanned and the STL files were used for CAD/CAM milling ( computer aided designing/ computer aided manufacturing) of new maxillary dentures (Group A), then the relining impression went through the conventional laboratory steps to fabricate (Group B) maxillary dentures. Both groups were evaluated regarding patient satisfaction by a specially designed questionnaire, retention values were measured by a digital force gauge at denture insertion appointment and two weeks later, geomagic software was used to evaluate dentures adaptation to oral tissues.

A cross-sectional study assessing barriers and facilitators to the sustainability of physical activity and nutrition interventions in early childhood education and care settings.

Int J Behav Nutr Phys Act

Global Centre for Preventive Health and Nutrition, Institute for Health Transformation, School of Health and Social Development, Faculty of Health, Deakin University, Burwood, VIC, 3125, Australia.

Background: Effective evidence-based physical activity and nutrition interventions to prevent overweight and obesity and support healthy child development need to be sustained within Early Childhood Education and Care (ECEC) services. Despite this, little is known about factors that influence sustainability of these programs in ECEC settings. Therefore, the aim of this study was to describe the factors related to sustainability of physical activity and nutrition interventions in ECEC settings and examine their association with ECEC service characteristics.

Latent fingerprints (LFPs) are invisible impressions that need to be developed before being used for criminal investigation; however, existing fingerprint visualization techniques face challenges, such as complex preparation and poor contrast. To advance practical fingerprint detection, green-emissive micron-sized curcumin/kaolin composites were synthesized a facile and cost-effective one-step physical cross-linking method, which exhibited unprecedented performance in developing diversified marks, including LFPs, knuckle prints, palm prints, and footprints, with clear three-level details on various substrates. Notably, the powders successfully developed LFPs that were aged for 30 days and even up to 100 days, meeting the stringent requirements for comprehensive forensic application.

Background: Due to the shortage of healthcare professionals with expertise in diagnosis and treatment of Alzheimer disease and related dementias, there are long wait times to be evaluated in dementia specialty clinics and no clear guidance about how to allocate limited resources. The purpose of this study was to examine utility of cognitive screening measures administered by clinic staff to determine level of cognitive impairment to aid in decisions about which patients may benefit from full diagnostic services.

Methods: Participants were 169 older adults who completed an intake interview, including a brief cognitive screening test, conducted by a neuropsychologist at a dementia specialty clinic.

BrainCheck, Austin, TX, USA.

Article Synopsis
  • The study validated BrainCheck Assess (BC-Assess) against the MoCA, a well-regarded paper-based cognitive test, to determine their correlation and equivalent cut-off scores for identifying cognitive impairment levels.
  • Using data from 55 participants aged 54-94, a strong correlation (0.77) was found between MoCA and BC-Assess scores, indicating that MoCA's cut-off scores correspond closely with BC-Assess cut-offs (89.6 for MCI and 68.5 for dementia).
  • Both assessments showed significant agreement in determining cognitive status, with overall agreement percentages of 70.9% for differentiating dementia from MCI/normal cognition and 83.6% for overall
