Association of Client and Provider Race with Approaches Pursued by Social Workers for Reducing Firearm Access.

Social workers assess and intervene to prevent harm among clients at risk of harm to self (HTS) and harm to others (HTO) with a firearm. This study sought to assess the impact of client race on social workers' approaches to reduce firearm access when they weighed voluntary (e.g., store out-of-home) and involuntary (e.g., extreme risk protection order) removal methods. We considered the role of social workers' self-identified race as a moderator of this relationship, comparing white (single race) and Black, Indigenous, and People of Color (BIPOC) social workers. A survey was distributed to Washington state social workers (n = 9073) who were presented with two case vignettes, each randomized to view the client's race as Black or white. Logistic regression was used to assess the association between the client's race and the pursuit of voluntary or involuntary methods, stratified by social workers' race. Among the participants (n = 1306), 26% pursued at least one involuntary care plan option for the HTS client, and 59% for the HTO client. The Black client at risk of HTS had lower odds of an involuntary care plan option compared to the white client (OR = 0.69, 95% CI 0.54-0.88), while the Black client at risk of HTO had higher odds of an involuntary care plan options (OR = 1.13, 95% CI 1.07-1.66). These associations were not statistically significantly different between white (single race selected) and BIPOC social workers. This study contributes to the growing understanding of potential racial disparities in social workers' decision-making regarding firearm access reduction strategies.

Integration of extreme risk protection orders into the clinical workflow: Qualitative comparison of clinician perspectives.

Extreme risk protection orders (ERPO) seek to temporarily reduce access to firearms for individuals at imminent risk of harming themselves and/or others. Clinicians, including physicians, nurse practitioners, and social workers regularly assess circumstances related to patients' risk of firearm-related harm in the context of providing routine and acute clinical care. While clinicians cannot independently file ERPOs in most states, they can counsel patients or contact law enforcement about filing ERPOs. This study sought to understand clinicians' perspectives about integrating ERPO counseling and contacting law enforcement about ERPOs into their clinical workflow. We analyzed responses to open-ended questions from an online survey distributed May-July of 2021 to all licensed physicians (n = 23,051), nurse practitioners (n = 8,049), and social workers (n = 6,910) in Washington state. Of the 4,242 survey participants, 1,126 (26.5%) responded to at least one of ten open-ended questions. Two coders conducted content analysis. Clinicians identified barriers and facilitators to integrating ERPOs into the clinical workflow; these influenced their preferences on who should counsel or contact law enforcement about ERPOs. Barriers included perceptions of professional scope, knowledge gaps, institutional barriers, perceived ERPO effectiveness and constitutionality, concern for safety (clinician and patient), and potential for damaging provider-patient therapeutic relationship. Facilitators to address these barriers included trainings and resources, dedicated time for counseling and remuneration for time spent counseling, education on voluntary removal options, and ability to refer patients to another clinician. Participants who were hesitant to be the primary clinician to counsel patients or contact law enforcement about ERPOs requested the ability to refer patients to a specialist, such as social workers or a designated ERPO specialist. Results highlight the complex perspectives across clinician types regarding the integration of ERPO counseling into the clinical workflow. We highlight areas to be addressed for clinicians to engage with ERPOs.

Temperature-dependent conformational change affecting Tyr11 and sweetness loops of brazzein.

The sweet protein brazzein, a member of the Csßα fold family, contains four disulfide bonds that lend a high degree of thermal and pH stability to its structure. Nevertheless, a variable temperature study has revealed that the protein undergoes a local, reversible conformational change between 37 and 3°C with a midpoint about 27°C that changes the orientations and side-chain hydrogen bond partners of Tyr8 and Tyr11. To test the functional significance of this effect, we used NMR saturation transfer to investigate the interaction between brazzein and the amino terminal domain of the sweet receptor subunit T1R2; the results showed a stronger interaction at 7°C than at 37°C. Thus the low temperature conformation, which alters the orientations of two loops known to be critical for the sweetness of brazzein, may represent the bound state of brazzein in the complex with the human sweet receptor.
