The size of local recurrence influences outcomes in chondrosarcoma: Significant impact observed in grade 2 tumours.

Background: Chondrosarcoma is the second most common bone malignancy. Chondrosarcoma is considered a surgical disease, and the role of surgical margin is important since local recurrence is known to decrease survival. The aim of this study was to investigate the timing of local recurrence and the size of local recurrence in post local recurrence survival in chondrosarcoma.

Addressing Known hypertensive disOrders of pregnancy in woMen of African descent in Canada (AKOMA): protocol for a mixed method study.

Background: Hypertensive disorders of pregnancy (HDP) predispose a woman to maternity-related cardiovascular morbidity and mortality. However, there is limited literature on HDP among women of African descent in Canada.

Methods And Design: A convergent mixed-method study will be used to investigate the intersection of self-reported HDP risks in women of African descent in Canada with a history of a HDP (quantitative, cross-sectional survey) and explore the perception and experiences of women of African descent living in Canada with a history of a HDP in relation to the intersection of risk factors (critical qualitative inquiry, interviews).

Estimating the risk of SARS-CoV-2 infection in New Zealand border arrivals.

Background: Travel restrictions and border controls were used extensively during the COVID-19 pandemic. However, the processes for making robust evidence-based risk assessments of source countries to inform border control policies was in many cases very limited.

Methods: Between April 2020 and February 2022, all international arrivals to New Zealand were required to spend 14 days in government-managed quarantine facilities and were tested at least twice.

Enhancing surgical margins: A key to survival in pelvic chondrosarcoma.

Introduction: Pelvic chondrosarcoma, originating in the cartilaginous tissue of the pelvis, presents unique surgical challenges due to its proximity to critical neurovascular structures and essential organs. The aim of this study was to explore the effect of changes in practice and improvements in understanding on the outcomes for patients undergoing surgery for pelvic chondrosarcoma.

Material And Methods: The study comprised a retrospective analysis of 216 patients making up 2 patient cohorts drawn from a single centre over 2 time periods (2003-2012 and 2013-2022).

Viral-mediated increased hippocampal neurogranin modulate synapses at one month in a rat model of controlled cortical impact.

Reductions of neurogranin (Ng), a calcium-sensitive calmodulin-binding protein, result in significant impairment across various hippocampal-dependent learning and memory tasks. Conversely, increasing levels of Ng facilitates synaptic plasticity, increases synaptogenesis and boosts cognitive abilities. Controlled cortical impact (CCI), an experimental traumatic brain injury (TBI) model, results in significantly reduced hippocampal Ng protein expression up to 4 weeks post-injury, supporting a strategy to increase Ng to improve function.
