SARS-CoV-2 introductions to the island of Ireland: a phylogenetic and geospatiotemporal study of infection dynamics.

Background: Ireland's COVID-19 response combined extensive SARS-CoV-2 testing to estimate incidence, with whole genome sequencing (WGS) for genome surveillance. As an island with two political jurisdictions-Northern Ireland (NI) and Republic of Ireland (RoI)-and access to detailed passenger travel data, Ireland provides a unique setting to study virus introductions and evaluate public health measures. Using a substantial Irish genomic dataset alongside global data from GISAID, this study aimed to trace the introduction and spread of SARS-CoV-2 across the island.

Integrating accelerometry, GPS, GIS and molecular data to investigate mechanistic pathways of the urban environmental exposome and cognitive outcomes in older adults: a longitudinal study protocol.

Introduction: Maintaining cognitive health in later life is a global priority. Encouraging individuals to make health behaviour changes, such as regular physical activity, and providing supportive urban environments can help maintain cognitive health, thereby preventing or delaying the progress of dementia and cognitive decline. However, the mechanistic pathways by which the urban environmental exposome influences cognitive health outcomes are poorly understood.

Increased Activity Level Following Total Ankle Replacement Results in Improved Patient Reported Outcomes.

While evidence highlights increased activity levels following total ankle replacement (TAR), the correlation between postoperative activity changes and ankle-surgery-specific patient-reported outcomes is unexplored. This retrospective cohort study investigates the effect of activity level changes on patient-reported outcomes, including the Manchester-Oxford Foot Questionnaire (MOXFQ) and patient satisfaction following TAR. Patient records from a single center performing TARs between January 2014 and February 2023 were reviewed alongside patient questionnaires completed preoperatively and at a mean follow-up of 44 ± 31 months postoperatively (range 6-134 months).

Sequential bilateral total ankle replacements: No difference in patient-reported outcomes between the first and second ankle.

Background: Total ankle replacement is an established treatment for end-stage arthritis. However, there is little data examining outcomes in sequential bilateral replacements. This study aimed to compare outcomes between first and second ankles in sequential replacement.
