There is growing concern among US-based clinicians, patients, policy makers, and in the media about the personal and community health risks associated with opioids. Perceptions about the efficacy and appropriateness of opioids for the management of chronic non-cancer pain (CNCP) have dramatically transformed in recent decades. Yet, there is very little social scientific research identifying the factors that have informed this transformation from the perspectives of prescribing clinicians. As part of an on-going ethnographic study of CNCP management among clinicians and their patients with co-occurring substance use, we interviewed 23 primary care clinicians who practice in safety-net clinical settings. In this paper, we describe the clinical and social influences informing three historic periods: (1) the escalation of opioid prescriptions for CNCP; (2) an interim period in which the efficacy of and risks associated with opioids were re-assessed; and (3) the current period of “opioid pharmacovigilance,” characterized by the increased surveillance of opioid prescriptions. Clinicians reported that interpretations of the evidence-base in favor of and opposing opioid prescribing for CNCP evolved within a larger clinical-social context. Historically, pharmaceutical marketing efforts and clinicians’ concerns about racialized healthcare disparities in pain treatment influenced opioid prescription decision-making. Clinicians emphasized how patients’ medical complexity (e.g. multiple chronic health conditions) and structural vulnerability (e.g. poverty, community violence) impacted access to opioids within resource-limited healthcare settings. This clinical-social history of opioid prescribing practices helps to elucidate the ongoing challenges of CNCP treatment in the US healthcare safety net and lends needed specificity to the broader, nationwide conversation about opioids.

Two-dimensional gel electrophoresis is a major technique in global analysis at the protein level. This paper presents an examination of spot volume data from three gel sets with radioactively labeled yeast Saccharomyces cerevisiae proteins. A strong variance versus mean dependence in data was found to be stabilized by applying a shifted logarithmic transformation. However, transformed data showed a remaining substantial variance heterogeneity for different proteins. Furthermore, examination of studentized residuals revealed that transformed data were approximately normally distributed and that there were spatial correlations among the measurement errors in the gel.

Background-Patients with a history of substance use are more likely than those without substance use to experience chronic noncancer pain (CNCP), to be prescribed opioids, and to experience opioid misuse or overdose. Primary care practitioners (PCPs) in safety-net settings care for low-income patients with CNCP and substance use, usually without specialist consultation. To inform communication related to opioid risk, we explored PCPs' and patients' perceptions of the risks of chronic opioid therapy.

Introduction California implemented multiple strategies, such as a Tobacco 21 law and compliance checks, to reduce high rates of youth e-cigarette use. However, the prevalence of use among underage youth and young adults continues rising. Little is known about how underage individuals obtain e-cigarettes. Methods We conducted structured qualitative interviews with 61 young adult (18-25 years old) vapers in the Los Angeles, CA area between June 2018 and June 2019. Interviews were comprehensive and designed to elicit information on participants’ thoughts, feelings, and experiences related to vaping. We queried participants on where and how they obtained vaping products, and participants discussed their experiences accessing products while under the legal age for sale. Directed content analysis was used to analyze interviews. Results Four concepts emerged: (1) Early experimentation of e-cigarettes with peers often occurred in a school setting, (2) Continued use of e-cigarettes commonly obtained through peer sales, (3) Inconsistent implementation of age restrictions at in-person retailers and (4) at online retailers. Participants had peers purchase products on their behalf and frequented in-person and online retailers with few to no age verification processes. Few participants faced challenges when purchasing products from retailers. Conclusions The current study’s findings offer insight into where and how underage individuals obtain vaping products despite restrictions to prevent them from doing so. Participant accounts of mixed ease of underage purchasing in person and online suggest retailer education is needed, along with additional research to inform more effective policies to reduce underage access to vaping products. Implications Despite legal age restrictions, e-cigarettes remain accessible to underage individuals, but specific strategies that underage youth utilize to evade legal age restrictions are largely unknown. We found that participants often accessed vaping products for the first time at school. Sales between peers were common, and participants also reported frequenting in-person retailers that inconsistently enforced age restrictions. Many participants reported little to no age verification online, though some believed online age verification measures were increasingly difficult to surpass. Knowledge of strategies underage youth utilize to access e-cigarettes can inform enforcement efforts.

This study sought to understand clinicians' and patients' experience managing chronic noncancer pain (CNCP) and opioids in safety-net primary care settings. This article explores the time requirements of safer opioid prescribing for medically and socially complex patients in the context of safety-net primary care. Methods: We qualitatively interviewed 23 primary care clinicians and 46 of their patients with concurrent CNCP and substance use disorder (past or current). We also conducted observations of clinical interactions between the clinicians and patients. We transcribed, coded, and analyzed interview and clinical observation recordings using grounded theory methodology. Results: Clinicians reported not having enough time to assess patients' CNCP, functional status, and risks for opioid misuse. Inadequate assessment of CNCP contributed to tension and conflicts during visits. Clinicians described pain conversations consuming a substantial portion of primary care visits despite patients' other serious health concerns. System-level constraints (eg, changing insurance policies, limited access to specialty and integrative care) added to the perceived time burden of CNCP management. Clinicians described repeated visits with little progress in patients' pain or functional status due to these barriers. Patients acknowledged clinical time constraints and reported devoting significant time to following new opioid management protocols for CNCP. Conclusions: Time pressure was identified as a major barrier to safer opioid prescribing. Efforts, including changes to reimbursement structures, are needed to relieve time stress on primary care clinicians treating medically and socially complex patients with CNCP in safety-net settings.
