Significance: Vaping both nicotine and cannabis in the past 30 days (co-vaping) is common among young adults. It is unclear which co-vaping patterns may increase substance use and dependence. We examined day-level associations between vaping patterns with vaping quantity.

Article Synopsis
  • Breast cancer is a common illness among women in the Caribbean, but not much is known about how their reproductive patterns affect when they get diagnosed.
  • A study was done to look at changes in these reproductive patterns and the age at which Caribbean women are diagnosed with breast cancer.
  • The study included over 1,000 women from various Caribbean countries, finding that younger women are more likely to start their periods earlier compared to older women.

Background: Most schwannomas are isolated tumours occurring in otherwise healthy people. However, bilateral vestibular schwannomas (BVS) or multiple non-vestibular schwannomas indicate an underlying genetic predisposition. This is most commonly -related schwannomatosis (SWN), but when BVS are absent, this can also indicate -related or -related SWN.

Article Synopsis
  • * A photoemission and density-functional theory study was conducted on three compounds to explore how different intercalant elements affect their electronic structures at both the bulk and surface levels.
  • * Findings reveal that as the atomic number of the intercalant increases, there’s greater hybridization with NbS-derived conduction states, resulting in the formation of new electronic states at the Fermi level, which explains previously observed anomalous states and sheds light on tuning magnetic interactions.

Article Synopsis
  • New diagnostic criteria for NF2-related schwannomatosis were established in 2022, leading to an updated prevalence study in the UK, which focused on the rate of de novo NF2 cases.
  • A total of 1,084 living NF2 patients were identified, indicating a prevalence of 1 in 61,332, with a striking 72% of cases being de novo, many of which were mosaic.
  • The findings also revealed that nonsense variants were most common (24.8%), while missense variants had a higher familial association (56%), emphasizing the importance of patient databases for accurate genetic counseling.
