Social determinants of unmet need for primary care: a systematic review.

Background: Despite primary care being largely free at the point of delivery, many Canadians experience challenges in accessing the services they need. A systematic review was conducted to summarize the evidence on the level of unmet need for primary care in Canada and its social determinants.

Methods: MEDLINE, Embase, Cochrane, and Web of Science databases were screened from inception to December 2023 using relevant search terms for primary care and unmet healthcare needs.

Transcriptomics of cumulus cells - a window into oocyte maturation in humans.

Background: Cumulus cells (CC) encapsulate growing oocytes and support their growth and development. Transcriptomic signatures of CC have the potential to serve as valuable non-invasive biomarkers for oocyte competency and potential. The present sibling cumulus-oocyte-complex (COC) cohort study aimed at defining functional variations between oocytes of different maturity exposed to the same stimulation conditions, by assessing the transcriptomic signatures of their corresponding CC.

Global distribution of large lunar craters: implications for resurfacing and impactor populations.

By using high-resolution altimetric measurements of the Moon, we produced a catalog of all impact craters ≥20 kilometers in diameter on the lunar surface and analyzed their distribution and population characteristics. The most-densely cratered portion of the highlands reached a state of saturation equilibrium. Large impact events, such as Orientale Basin, locally modified the prebasin crater population to ~2 basin radii from the basin center.
