Aligning Science Across Parkinson's (ASAP) Collaborative Research Network, Chevy Chase, MD, 20815, USA.

Gastrointestinal (GI) involvement in Lewy body diseases (LBDs) has been observed since the initial descriptions of patients by James Parkinson. Recent experimental and human observational studies raise the possibility that pathogenic alpha-synuclein (⍺-syn) might develop in the GI tract and subsequently spread to susceptible brain regions. The cellular and mechanistic origins of ⍺-syn propagation in disease are under intense investigation.

Early-stage and metastatic breast cancers (MBC) can exhibit genomic heterogeneity, even within the same individual. Response to therapy in metastatic breast cancer patients with multiple metastases can also be heterogeneous, with different degrees of responsiveness to the same drug(s) across metastatic sites, termed "mixed response," within the same patient. Whether this treatment response variability is influenced by factors such as intrinsic tumor characteristics of metastatic lesions and/or the microenvironment is unknown.

Re-examining the pathobiological basis of gait dysfunction in Parkinson's disease.

Trends Neurosci

January 2025

Department of Neurosurgery, Department of Surgery, University of Toronto, Toronto, Ontario, Canada; Krembil Brain Institute, Toronto Western Hospital, Toronto, Ontario, Canada; Center for Advancing Neurotechnological Innovation to Application (CRANIA), Toronto, Ontario, Canada.

Parkinson's disease (PD) is a significant source of morbidity, especially with an aging population. Gait problems, particularly freezing of gait (FOG), remain a persistent issue, causing falls and reduced quality of life without consistent responses to therapies. PD and related symptoms have classically been attributed to dopamine deficiency secondary to substantia nigra degeneration from Lewy body (LB) and Lewy neurite (LN) infiltration.

Background: Collaborative research consortia provide an efficient method to increase sample size, enabling evaluation of subgroup heterogeneity and rare outcomes. In addition to missing data challenges faced by all cohort studies like nonresponse and attrition, collaborative studies have missing data due to differences in study design and measurement of the contributing studies.

Methods: We extend ROSETTA, a latent variable method that creates common measures across datasets collecting the same latent constructs with only partial overlap in measures, to define a common measure of socioeconomic status (SES) across cohorts with varying indicators in the Environmental influences on Child Health Outcomes Cohort, a consortium of pregnancy and pediatric cohorts.

Managing conflicts of interest (COIs) in scientific decision-making is important for minimizing bias and fostering public trust in science. Proper management of COIs has added significance when scientists are making decisions that impact public policy, such as assessing substances for carcinogenicity. The International Agency for Research on Cancer (IARC) organizes expert working groups to identify putative carcinogens and determine whether or not the hazard is likely to present significant potential harm to humans.

We investigated the effect of anticipation on the proactive and reactive neuromechanical responses of the distal leg muscles in 20 young adults to anticipated and unanticipated rapid anterior or posterior treadmill-induced balance perturbations applied during walking. We quantified local medial gastrocnemius (MG) and tibialis anterior (TA) neuromechanics using cine B-mode ultrasound and surface electromyography before, during, and after the perturbation. Our findings partially supported the hypothesis that anticipated perturbations would elicit greater proactive agonist muscle adjustments than unanticipated perturbations.
