We developed and evaluated Cox proportional hazards models and translated them into web-based applications to predict incident cognitive impairment in cognitively normal older adults using clinical data, with optional biomarker inputs. Data were drawn from cognitively unimpaired participants in the Alzheimer's Disease Neuroimaging Initiative (ADNI). Models included demographic and neuropsychological variables, with optional genetic, neuroimaging, and fluid (plasma and CSF) biomarkers. Performance was assessed using the C-index, calibration slope, and decision curve analysis, with internal validation via bootstrap resampling. Key models were externally validated in the Harvard Aging Brain Study. The ADNI sample comprised 729 participants (median age 73 years; 45% male). A clinical model including age, education, Montreal Cognitive Assessment, and delayed word recall showed acceptable discrimination (C-index 0.721; CI 0.672-0.772) and strong calibration (slope 0.940). Adding biomarkers improved performance, with the highest discrimination observed for a model including FDG and florbetapir PET uptake (C-index 0.805; CI 0.759-0.886). Discrimination remained stable after internal and external validation, while calibration was weaker for most plasma biomarkers. Five web applications (CogStrat) were developed using clinical data alone or combined with hippocampal volume, CSF tau/Aβ42, plasma neurofilament light chain, or FDG and florbetapir PET. These tools provide individualized risk group classifications, 5-year risk estimates, and 10-year cumulative incidence curves.

Results indicate high feasibility with visit completion frequently exceeding 70% and high user satisfaction primarily due to reduced travel burden and costs. Clinical outcomes appear comparable to in-person care, yet evidence on efficiency remains inconclusive. Current literature suffers from methodological limitations, including small sample sizes, U.S. geographic bias, and a lack of standardized outcome taxonomies. Notably, we identify a recurring \"augmentation bias\" in comparative trial designs: experimental arms frequently receive more clinical attention than controls.

Furthermore, barriers regarding the digital divide and concerns about international privacy regulations (e.g., GDPR/HIPAA) remain unresolved.

Accumulating evidence indicates that the interplay between polygenic risk and childhood trauma influences not only the likelihood of psychosis onset but also the emergence of specific symptom dimensions during clinical high-risk states and early stages of illness. Yet, existing theoretical frameworks tend to consider genetic predisposition and environmental exposure as parallel or additive processes, offering limited insight into their developmental convergence.

To quantify the temporal relationships between oropharyngeal phases and breathing during water and jelly swallows, we retrospectively analyzed the electrokinesiographic study of swallowing (EKSS) from 38 patients with the parkinsonian variant of MSA (MSA-P), 16 patients with the cerebellar variant of MSA (MSA-C), 21 patients with PD, and 15 healthy controls.
