Examining evidence of lung cancer stigma among health-care trainees.

BACKGROUND: Innovations in lung cancer control and care have started to transform the landscape of lung cancer outcomes, but lung cancer stigma and biases have been implicated as a deterrent to realizing the promise of these innovations. Research has documented lung cancer stigma among the general public and lung cancer survivors (self-blame), as well as clinicians across many disciplines. However, studies have not explored lung cancer stigma in health-care trainees. These data seek to address that gap and inform efforts to prevent the emergence or mitigate the presence of lung cancer stigma among future clinicians. METHODS: Using clinical vignettes and a 2x2 factorial design, this investigation evaluated the impact of a history of smoking (yes vs no) and cancer diagnosis (lung vs colorectal) on perceptions of the described patient among 2 groups of preclinical health-care trainees (medical = 94 and nursing = 138). A charitable giving paradigm also asked participants to donate provided funds to 1 of 2 cancer advocacy organizations: one serving the lung cancer community and one serving the colorectal cancer community. RESULTS: In study 1, results revealed a consistent pattern of statistically significant and medium to large effect size differences regarding stigmatized perceptions (eg, higher stigmatizing behavior, increased pity, greater anger, and less helping) for individuals with a history of smoking but no reliable differences regarding cancer diagnosis. Analysis of data from nursing trainees in study 2 showed a similar pattern of statistically significant and medium to large effects pertaining to stigma behavior and perceptions of individuals who had a history of smoking depicted in the vignettes. The charitable giving paradigm did not identify any reliable difference between the groups in either study. CONCLUSIONS: Findings revealed a consistent pattern of health-care trainee perceptions that varied by smoking status but much less evidence that the cancer diagnosis contributed to different perceptions. This suggests that efforts to integrate consideration of stigma and biases in health-care training needs to adopt an approach that seeks to mitigate or eliminate stigmatizing perceptions and behaviors toward individuals with a history of smoking.

Pharmacological profiling of stretch activated channels in proprioceptive neurons.

Proprioception in mammals and invertebrates occurs through stretch activated ion channels (SACs) localized in sensory endings. In mammals, the primary organs for proprioception are the intrafusal muscle spindles embedded within extrafusal muscle. In invertebrates there are varied types of sensory organs, from chordotonal organs spanning joints to muscle receptor organs (MRO) which are analogous to the mammalian muscle spindles that monitor stretch of muscle fibers. A subset of SACs are the PIEZO channels. They are comprised of a distinct type of protein sequence and are similar among species, from mammals to invertebrates. We screened several new agents (YODA 1, JEDI 2, OB 1 and DOOKU) which have been identified to act on SACs of the PIEZO 1 subtype. JEDI 2 increased activity in the crayfish MRO but not the crab chordotonal organs. The SACs of the crustacean proprioceptors have not been satisfactorily pharmacologically classified, nor has their molecular makeup been identified. We screened these pharmacological agents on model sensory organs in crustaceans to learn more about their subtype classification and compare genomic profiles of related species.
