Fox Insight at 5 years - a cohort of 54,000 participants contributing longitudinal patient-reported outcome, genetic, and microbiome data relating to Parkinson's disease.

Fox Insight is an online, longitudinal study of over 54,000 people with and without Parkinson's disease, facilitating discovery, validation, and reproducibility in Parkinson's disease research. The study administers routine longitudinal assessments, one-time questionnaires on an array of topics such as environmental exposure or COVID-19, plus genetic and microbiome data collection. Researchers can explore and download patient-reported outcomes data and Parkinson's disease related genetic variants upon completing a Data Use Agreement.

American Football Play and Parkinson Disease Among Men.

Importance: Parkinsonism and Parkinson disease (PD) are known to result from repetitive head impacts from boxing. Repetitive head impacts from American football may also be associated with increased risk of neurodegenerative pathologies that cause parkinsonism, yet in vivo research on the association between football play and PD is scarce and limited by small samples and equivocal findings.

Objective: To evaluate the association between football participation and self-reported parkinsonism or PD diagnosis.

Design of a virtual longitudinal observational study in Parkinson's disease (AT-HOME PD).

Objective: The expanding power and accessibility of personal technology provide an opportunity to reduce burdens and costs of traditional clinical site-centric therapeutic trials in Parkinson's disease and generate novel insights. The value of this approach has never been more evident than during the current COVID-19 pandemic. We sought to (1) establish and implement the infrastructure for longitudinal, virtual follow-up of clinical trial participants, (2) compare changes in smartphone-based assessments, online patient-reported outcomes, and remote expert assessments, and (3) explore novel digital markers of Parkinson's disease disability and progression.

N-glycosylation status of beta-haptoglobin in sera of patients with prostate cancer vs. benign prostate diseases.

N-glycosylation status of purified beta-haptoglobin separated from sera of patients with prostate cancer was studied in comparison to that of sera from patients with benign prostate diseases, or normal subjects. Two different approaches, as summarized below, one based on binding of lectins and antibodies to beta-haptoglobin, the other on mass spectrometry of released N-linked glycans from beta-haptoglobin, were performed. Some of the results were useful for distinction of prostate cancer vs.
