MD3F: Multivariate Distance Drift Diffusion Framework for High-Dimensional Datasets.

High-dimensional biomedical datasets have become easier to collect in the last two decades with the advent of multi-omic and single-cell experiments. These can generate over 1000 measurements per sample or per cell. More recently, focus has been drawn toward the need for longitudinal datasets, with the appreciation that important dynamic changes occur along transitions between health and disease.

A Pilot Study Exploring Caregivers' Experiences Related to the Use of a Smart Toothbrush by Children with Autism Spectrum Disorder.

Background: Research on caregivers for children with intellectual disabilities, particularly those with autism spectrum disorder (ASD), has highlighted several obstacles to achieving better oral health. These include challenges with tolerating oral care, sensory processing differences, uncooperative behaviors, and communication impairments. There is limited understanding of what caregivers would consider "successful assistance" in improving oral health for these children.

Oral Health Outcomes In An HIV Cohort With Comorbidities- Implementation Roadmap For A Longitudinal Prospective Observational Study.

Long-term antiretroviral therapy (ART) perpetually suppresses HIV load and has dramatically altered the prognosis of HIV infection, such that HIV is now regarded as a chronic disease. Side effects of ART in Patients With HIV (PWH), has introduced new challenges including "metabolic" (systemic) and oral complications. Furthermore, inflammation persists despite great viral load suppression and normal levels of CD4 cell count.
