Objective: Since the federal Canadian government legalized cannabis in 2018, cannabis use in the general population has slightly increased. However, little is known about the impact of cannabis legalization on pattens of cannabis use in psychiatric populations.

Method: We studied changes in daily/almost daily and average 30-day cannabis use amongst individuals currently using cannabis who reported past 12-month experiences of specific mental health disorders and among those without past 12-month experiences of any mental health disorder before and after Canadian legalization of recreational cannabis use ( = 13,527).

This study examined differences in quit attempts, 1-month quit success, and vaping status at follow-up among a cohort of 3709 daily smokers with and without depression, anxiety, and regular alcohol use who participated in both the 2018 and 2020 International Tobacco Control Four Country Smoking and Vaping (ITC 4CV) Surveys. At baseline, a survey with validated screening tools was used to classify respondents as having no, or one or more of the following: 1) depression, 2) anxiety, and 3) regular alcohol use. Multivariable adjusted regression analyses were used to examine whether baseline (2018) self-report conditions were associated with quit attempts; quit success; and vaping status by follow-up (2020).

In myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) with TP53 aberrations, dissecting the interaction amongst patient, disease and treatment factors are important for therapeutic decisions and prognostication. This retrospective analysis included patients with newly diagnosed MDS (>5% blasts) and AML with TP53 mutation(s) treated at MD Anderson Cancer Center. We factored patient age, TP53 aberration burden, therapy intensity and use of venetoclax in the AML subgroup, and allogeneic hematopoietic stem cell transplantation (HSCT) to interrogate outcomes.

Article Synopsis
  • Fat grafting is widely used in aesthetic and reconstructive surgery but can experience complications like fat necrosis, which is influenced by factors such as fat aspiration and graft size.
  • The study explored how the expression of vascular endothelial growth factor A (VEGF) and various cytokines by adipose-derived stromal cells (ADSCs) and differentiated adipocytes affects fat graft survival and angiogenesis.
  • Results showed that many ADSCs have high VEGF levels, promoting tissue survival post-transfer, but differentiation into adipocytes can take time and may not provide immediate support for angiogenesis.

The age-associated mutational state of clonal haematopoiesis (CH) is linked to multiple adverse health outcomes. As higher risk CH can lead to progressive neoplastic or vascular disease, there is interest in developing clinical trials to mitigate risk associated with CH. Given the high prevalence of CH, data from clinical trials could have broad public health implications for screening and therapy.

Objective: Online and lab-based experiments examining the impact of alcohol labels typically test a one-time exposure to labels and assess short-term, non-behavioural outcomes. These studies do not simulate a real-world label dose or assess actual alcohol use. This pilot aimed to develop a new protocol for testing alcohol labels that better reflects real-world exposure by presenting labels on consumers' own alcohol products over time and assessing effects on several outcomes, including alcohol use.
