Tracking the course of depressive and anxiety symptoms across adolescence (the CATS study): a population-based cohort study in Australia.

Background: Adolescent mental health appears to be in crisis, yet few studies have comprehensively charted the course of common mental disorders (CMDs; depression and anxiety) across this key life stage. We aimed to describe the course of CMD symptoms in adolescence by summarising annual prevalence, cumulative incidence, and course for depression and anxiety, both separately and as comorbid CMDs, by sex assigned at birth in a contemporary Australian cohort.

Methods: The Child to Adult Transition Study (CATS) was established in 2012 to form a representative cohort of adolescents in Melbourne, VIC, Australia.

Causal inference in multi-cohort studies using the target trial framework to identify and minimize sources of bias.

Longitudinal cohort studies, which follow a group of individuals over time, provide the opportunity to examine causal effects of complex exposures on long-term health outcomes. Utilizing data from multiple cohorts has the potential to add further benefit by improving precision of estimates through data pooling and by allowing examination of effect heterogeneity through replication of analyses across cohorts. However, the interpretation of findings can be complicated by biases that may be compounded when pooling data, or, contribute to discrepant findings when analyses are replicated.

Bacterial cross-feeding can promote gene retention by lowering gene expression costs.

Gene loss is expected in microbial communities when the benefit of obtaining a biosynthetic precursor from a neighbor via cross-feeding outweighs the cost of retaining a biosynthetic gene. However, gene cost primarily comes from expression, and many biosynthetic genes are only expressed when needed. Thus, one can conversely expect cross-feeding to repress biosynthetic gene expression and promote gene retention by lowering gene cost.

Prescribers and patients drive maintenance therapy patterns in a community oncology practice: National guidelines versus the real-world experience.

Objective: Previous studies have shown that first-line (1L) maintenance therapy (MT) with poly(ADP-ribose) polymerase inhibitors and/or bevacizumab improves outcomes among patients with advanced ovarian cancer (OC); however, these treatments are underutilized. This study aimed to provide a real-world understanding of MTs among patients with advanced OC who received 1L platinum-based chemotherapy (PBC).

Methods: A retrospective chart review using iKnowMed electronic health records to identify patients aged ≥18 years with advanced OC who initiated 1L PBC between January 1, 2018-December 31, 2020.
