Article Abstract
Objective: The past decade has seen a rapid increase in the publication of studies using trajectory analysis to describe the course of osteoarthritis (OA) symptoms. The aim of this systematic review was to describe the distinct trajectories for OA outcomes and the predictors of these trajectories.
Methods: Medline and PsycInfo databases were searched for relevant studies. Selection criteria were 1) patients ≥18 years of age, 2) patients at high risk of or diagnosed with knee or hip OA, 3) studies aiming to identify homogeneous subgroups with distinct trajectories of clinical outcomes, and 4) methodology and analysis designed to identify trajectories (longitudinal design and repeated measures). The search was limited to publications in English or French.
Results: Of the 5,177 abstracts retrieved, 44 studies met the inclusion criteria; 21 described the disease progression before surgery. The most frequent outcomes were pain and physical function. Up to 6 trajectories of pain were found for hip and knee OA. For function, between 1 and 5 trajectories were identified for knee OA. Low educational level, high body mass index, and high number of comorbidities were the most reported predictors of bad evolution.
Conclusion: Although studies were heterogeneous (outcome, subgroup number, and composition), they revealed stable OA trajectories over time. This finding suggests that OA is a chronic disease that does not inevitably worsen in terms of patient-reported symptoms.

Background: Breastfeeding is the optimal source of nutrition for infants and young children, essential for their healthy growth and development. However, a gap in cohort studies tracking breastfeeding up to six months postpartum may lead caregivers to miss critical intervention opportunities.
Methods: This study conducted a three-wave prospective cohort analysis to examine maternal breastfeeding trajectories within the first six months postpartum and to develop risk prediction models for each period using advanced machine learning algorithms.
Study of mechanisms by which antibodies recognize different viral strains is necessary for the development of new drugs and vaccines to treat COVID-19 and other infections. Here, we report 2.5 Å cryo-EM structure of the SARS-CoV-2 Delta trimeric S-protein in complex with Fab of the recombinant analog of REGN10987 neutralizing antibody.
Objective: Excess cholesterol loading on arterial macrophages is linked to foam cell formation, atherosclerosis and cardiovascular risk in rheumatoid arthritis (RA). However, the effect of changes in cholesterol loading on coronary plaque trajectory and the impact of RA therapies on this relationship are unknown. We investigated the association between variations in cholesterol loading capacity (CLC) over time and atherosclerosis progression.
The corpus callosum (CC) is the largest white matter fiber bundle connecting the two hemispheres, facilitating interhemispheric integration and hemispheric specialization. Neuroimaging studies have identified the CC as a marker for aging and various neuropsychiatric disorders. However, high-resolution imaging and detailed lifespan characterizations of CC morphology and connectivity remain limited.
Context: Targeted and directed rehabilitation with a healthcare provider can be an effective approach in the treatment of concussion, particularly for patients with protracted recovery, high symptom reporting, cervicogenic dysfunction, musculoskeletal involvement, and/or vestibular/oculomotor dysfunction. While many environmental and intrinsic medical history factors may influence concussion recovery, little is known about whether an individual's recovery trajectory can be influenced by the amount of time taken to receive rehabilitation. The purpose of this study was to evaluate recovery trajectories of concussion patients requiring targeted multimodal rehabilitation after a specialty concussion clinic visit within ≤3 days, 4 to 7 days, and >7 days.
