Intracameral phenylephrine for surgical mydriasis and intraoperative floppy-iris syndrome: systemic adverse effects and optimal dose.

Phenylephrine, a potent sympathomimetic, induces mydriasis via iris dilator muscle contraction. Intracameral (IC) phenylephrine has been successfully used in cataract surgery for initial mydriasis, maintaining mydriasis, and management of intraoperative floppy-iris syndrome. Serious systemic adverse events (mainly cardiovascular) have been described with topical phenylephrine drops, but we found very little evidence of such adverse events associated with IC phenylephrine use.

Medical student perspectives on substance misuse education in the medical undergraduate programme: a grounded theory approach.

Background: Substance misuse teaching within the undergraduate medical curriculum has been underrepresented compared to more traditional medical topics. In response several national curriculum reviews such as the most recent UK department of health initiative (DOH) have identified deficiencies in substance misuse education and have suggested curriculum interventions for local faculties to implement. The student perspective however has largely been muted during this process and this study aims to explore this using a constructivist grounded theory approach.

Cancer Research UK'S obesity campaign in 2018 and 2019: effective health promotion or perpetuating the stigmatisation of obesity?

In 2018 and 2019 Cancer Research UK (CRUK) launched a controversial advertising campaign to inform the British public of obesity being a preventable cause of cancer. On each occasion the advertisements used were emotive and provoked frustration among the British public which was widely vocalised on social media. As well serving to educate the public of this association, the advertisements also had the secondary effect of acting as health promotion through social marketing, a form of advertising designed to influence behavioural changes.
