Trends in Varenicline Use for Tobacco Cessation, and Their Implications

BACKGROUND

Tobacco use remains a leading cause of death in the U.S. Varenicline is a preferred medication for tobacco cessation, and a prior report in the literature showed its use fell dramatically after the voluntary recall of Chantix (name-brand varenicline) in July 2021.

OBJECTIVES

Working with data on prescriptions for varenicline and nicotine-replacement therapy (NRT), we studied use from 2018 to 2023 to determine if varenicline use had recovered or if there had been a compensatory increase in NRT use.

METHODS

Data are yearly from state employees and their dependents who were aged >18 years and were health-insurance beneficiaries of the Washington Public Employees Benefits Board from July 2018 through June 2023. Data include numbers of tobacco users and numbers of prescriptions filled.

RESULTS

The 5-year prevalence of tobacco use among 224,816 beneficiaries was 4.6%. The percentage of tobacco users who filled a prescription for varenicline fell from highs of 9.5% and 9.6% in the 2018-2019 and 2019-2020 year to lows of 5.3% and 6.4% in the 2021-2022 and 2022-2023 years. For nicotine replacement therapy, prescriptions rose modestly over the 5 years, from 4.5% in 2018-2019 to 6.0% in 2022-2023.

DISCUSSION

Varenicline use dropped after the voluntary recall of Chantix by Pfizer in mid-2021 and has not returned to pre-recall levels.

CONCLUSION

Pharmacists and other clinicians should address this drop, in addition to addressing longer-term challenges to increasing varenicline use; these include the requirement for a prescription and the black-box warning by the Food and Drug Administration, rescinded in 2016.

An Antibody-Drug Conjugate Directed to Tissue Factor Shows Preclinical Antitumor Activity in Head and Neck Cancer as a Single Agent and in Combination with Chemoradiotherapy

Head and neck squamous cell carcinoma (HNSCC) is a solid tumor type that arises in the squamous epithelial cells lining the mucosal surfaces of the upper aerodigestive tract. Long-term survival of patients with advanced disease stage remains disappointing with current treatment options. We show that tissue factor is abundantly expressed on patient-derived HNSCC cell lines, xenograft tumor material, and tumor biopsies from patients with HNSCC. Tisotumab vedotin (TV) is an antibody-drug conjugate (ADC) directed to tissue factor, a protein expressed in many solid tumors. HNSCC cells and xenograft tumors were efficiently eliminated in vitro and in vivo with TV-monotherapy compared with treatment with a control antibody conjugated to monomethyl auristatin E (MMAE). Antitumor activity of TV was also tested in vivo in combination with chemoradiotherapy, standard of care for patients with advanced stage HNSCC tumors outside the oral cavity. Preclinical studies showed that by adding TV to chemoradiotherapy, survival was markedly improved, and TV, not radiotherapy or chemotherapy, was the main driver of antitumor activity. Interestingly, TV-induced cell death in xenograft tumors showed an influx of macrophages indicative of a potential immune-mediated mode-of-action. In conclusion, on the basis of these preclinical data, TV may be a novel treatment modality for patients suffering from head and neck cancer and is hypothesized to improve efficacy of chemoradiotherapy.

SIGNIFICANCE

This work shows preclinical in vitro and in vivo antitumor activity of the antibody-drug conjugate Tisotumab vedotin in head and neck cancer models, and enhanced activity in combination with chemoradiotherapy, supporting further clinical development for this cancer type.

Exploring the Impact of the COVID-19 Pandemic on Employees' Workplace Health Promotion Preferences

PURPOSE

The COVID-19 pandemic has led to profound changes in the workplace as well as increases in stress, missed preventive care, and other health concerns. There is limited research since the onset of the pandemic on employees' primary health concerns and their willingness to engage with workplace health promotion (WHP) programs to address these needs. We conducted this survey about employees' current health priorities as a first step to exploring whether WHP programs need to evolve to be responsive to employees' needs at this stage of the pandemic.

DESIGN

National cross-sectional survey.

SETTING

United States, April 29-May 5, 2022.

SUBJECTS

2053 Americans employed part or full time.

MEASURES

17-item online survey assessing demographics, health priorities, and impact of the pandemic on health.

ANALYSIS

Descriptive statistics, SPSS Version 19.

RESULTS

Employees' most common health concerns included work/life balance and stress (each cited by 55%). Nearly half (46%) said their health or well-being was affected by the pandemic; within this group, the most common concerns were stress (66%), anxiety (61%), sleep (49%), and depression (48%). Almost all (94%) indicated they would be open to receiving support from their employers.

CONCLUSION

This research is a first step in learning about employees' current health priorities and how they may have changed. WHP researchers and practitioners can determine how their programs align with current priorities. Our future research will explore employees' preferences, heath behaviors, and their current workplace environments in more depth.

Attention challenges in Kabuki syndrome

BACKGROUND

Understanding the specific neurobehavioural profile of rare genetic diseases enables clinicians to provide the best possible care for patients and families, including prognostic and treatment advisement. Previous studies suggested that a subset of individuals with Kabuki syndrome (KS), a genetic disorder causing intellectual disability and other neurodevelopmental phenotypes, have attentional deficits. However, these studies looked at relatively small numbers of molecularly confirmed cases and often used retrospective clinical data instead of standardised assessments.

METHODS

Fifty-five individuals or caregivers of individuals with molecularly confirmed KS completed assessments to investigate behaviour and adaptive function. Additionally, information was collected on 23 unaffected biological siblings as controls.

RESULTS

Attention Problems in children was the only behavioural category that, when averaged, was clinically significant, with the individual scores of nearly 50% of the children with KS falling in the problematic range. Children with KS scored significantly higher than their unaffected sibling on nearly all behavioural categories. A significant correlation was found between Attention Problems scores and adaptive function scores (P = 0.032), which was not explained by lower general cognitive ability.

CONCLUSIONS

We found that the rates of children with attentional deficits are much more elevated than would be expected in the general population, and that attention challenges are negatively correlated with adaptive function. When averaged across KS participants, none of the behavioural categories were in the clinically significant range except Attention Problems for children, which underscores the importance of clinicians screening for attention deficit hyperactivity disorder (ADHD) in children with KS.

Bridging Culture and Language: Encouraging Bilingual/Multicultural Individuals to Act as Information Navigators for Their Loved-Ones and Communities during the COVID-19 Pandemic

Linguistically diverse communities face barriers to receiving appropriate health information. COVID-19 exacerbated these health-communication inequities. University of Washington researchers surveyed bilingual staff, students, and medical interpreters - desiring training to become effective communicators of COVID-19 information to their social networks and language communities. In response, the COVID-19 Information Navigator Training was developed and pre-tested with professional networks and members of the target audience. The final training comprised three interactive modules and short quizzes. Evaluation surveys measured Information Navigators' confidence in providing COVID-19 information to their social networks. Surveys included questions on the participants' language or cultural community, the perceived value of the training, and their ability to communicate COVID-19 information. Among 393 participants who enrolled in the training, 284 completed the survey. Significant differences in confidence before and after the course were found in detecting COVID misinformation in the news and social media (pre-course mean: 3.83, post-course mean: 4.63; absolute mean difference was 0.82 points higher in the post-evaluation on the 5-point likert scale, 95% CI: 0.70-0.93, p < .01). Training multicultural volunteers to disseminate information to their social networks is a promising strategy for reaching linguistically diverse communities with up-to-date information during health emergencies.

Development and maturation of the occupational health services research field in the United States over the past 25 years: Challenges and opportunities for the future

Work is an important social determinant of health; unfortunately, work-related injuries remain prevalent, can have devastating impact on worker health, and can impose heavy economic burdens on workers and society. Occupational health services research (OHSR) underpins occupational health services policy and practice, focusing on health determinants, health services, healthcare delivery, and health systems affecting workers. The field of OHSR has undergone tremendous expansion in both definition and scope over the past 25 years. In this commentary, focusing on the US, we document the historical development and evolution of OHSR as a research field, describe current doctoral-level OHSR training, and discuss challenges and opportunities for the OHSR field. We also propose an updated definition for the OHSR field: Research and evaluation related to the determinants of worker health and well-being; to occupational injury and illness prevention and surveillance; to healthcare, health programs, and health policy affecting workers; and to the organization, access, quality, outcomes, and costs of occupational health services and related health systems. Researchers trained in OHSR are essential contributors to improvements in healthcare, health systems, and policy and programs to improve worker health and productivity, as well as equity and justice in job and employment conditions. We look forward to the continued growth of OHSR as a field and to the expansion of OHSR academic training opportunities.

Opportunities to Improve Tobacco Control for State Agency Employees

OBJECTIVE

The aim of the study is to explore tobacco-related knowledge and perceptions at Washington State (WA) agencies.

METHODS

The study used a cross-sectional employee survey and qualitative focus groups with managers/supervisors. We produced descriptive statistics to examine differences in awareness and perceptions of tobacco-control efforts among employees and conducted a rapid thematic analysis of focus group data.

RESULTS

Of employees, only 18% with a history of tobacco use had used their agency's cessation benefits. Employees who did not use tobacco and who had higher education had more favorable attitudes toward tobacco-control efforts. In the focus groups, manager/supervisors described limited tobacco cessation promotion at their agency, barriers to tobacco control implementation, and concerns about the perceived effectiveness of additional tobacco-control efforts.

CONCLUSIONS

State agencies should increase promotion of tobacco control policies and programs to increase awareness and reduce disparities in tobacco use.

Title: Age, sex, and survival following ventricular fibrillation cardiac arrest: a mechanistic evaluation of the ECG waveform: Short title: Age, sex, and survival via VF waveform in OHCA

BACKGROUND

Studies of outcome differences by sex in out-of-hospital cardiac arrest (OHCA) have produced mixed results that may depend on age, a potential surrogate for menopausal status.

OBJECTIVE

We used quantitative measures of ventricular fibrillation (VF) waveforms - indicators of the myocardium's physiology - to assess whether survival differences according to sex and age group may be mediated via a biologic mechanism.

METHODS

We conducted a cohort study of VF-OHCA in a metropolitan EMS system. We used multivariable logistic regression to assess the association of survival to hospital discharge with sex and age group (<55, ≥55 years). We determined the proportion of outcome difference mediated by VF waveform measures: VitalityScore and amplitude spectrum area (AMSA).

RESULTS

Among 1526 VF-OHCA patients, the average age was 62 years, and 29% were female. Overall, younger women were more likely to survive than younger men (survival 67% vs 54%, p=0.02), while survival among older women and older men did not differ (40% vs 44%, p=0.3). Adjusting for Utstein characteristics, women <55 compared to men <55 had greater odds of survival to hospital discharge (OR=1.93, 95% CI 1.23-3.09), an association not observed between the ≥55 groups. Waveform measures were more favorable among women and mediated some of the beneficial association between female sex and survival among those <55 years: 47% for VitalityScore and 25% for AMSA.

CONCLUSIONS

Women <55 years were more likely to survive than men <55 years following VF-OHCA. The biologic mechanism represented by VF waveform mediated some, though not all, of the outcome difference.

What happens in Vegas, stays in your lungs: an assessment of fine particulate matter in casinos that prohibit and allow smoking in Las Vegas, Nevada, USA

INTRODUCTION

Despite progress in adoption of smoke-free policies, smoking in casinos is allowed in some US states, including Nevada. In 2020, for the first time, a resort-style casino in Las Vegas prohibited smoking voluntarily. This study is the first to assess air quality in this casino and compare results with similar casinos that allow smoking.

METHODS

A real-time personal aerosol monitor evaluated particulate matter with a diameter <2.5 µm (PM2.5), a surrogate for secondhand smoke (SHS). PM2.5 was measured at eight Las Vegas casinos, including the smoke-free casino. Each casino was visited twice, and PM2.5 was assessed in smoking-permitted gaming areas and areas where smoking is otherwise prohibited.

RESULTS

Average PM2.5 levels were significantly higher in casinos that allow smoking, for both casino gaming areas and areas where smoking is otherwise prohibited (p<0.05). Mean PM2.5 in gaming areas was 164.9 µg/m3 in casinos that allow smoking and 30.5 µg/m3 in the smoke-free casino. Mean PM2.5 in areas where smoking is otherwise prohibited was 83.2 µg/m3 in casinos which allowed smoking in gaming areas, and 48.1 µg/m3 in the smoke-free casino.

CONCLUSION

Despite robust evidence about the harms of SHS, tens of thousands of casino employees and tens of millions of tourists are exposed to high levels of SHS in Las Vegas casinos annually, with PM2.5 levels 5.4 times higher in gaming areas when compared with a smoke-free casino. The only way to protect people from SHS exposure is to prohibit smoking in all indoor areas.

Systematic study of tissue factor expression in solid tumors

BACKGROUND

Elevated tissue factor (TF) expression, although restricted in normal tissue, has been reported in multiple solid cancers, and expression has been associated with poor prognosis. This manuscript compares TF expression across various solid tumor types via immunohistochemistry in a single study, which has not been performed previously.

AIMS

To increase insight in the prevalence and cellular localization of TF expression across solid cancer types, we performed a detailed and systematic analysis of TF expression in tumor tissue obtained from patients with ovarian, esophageal, bladder, cervical, endometrial, pancreatic, prostate, colon, breast, non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), and glioblastoma. The spatial and temporal variation of TF expression was analyzed over time and upon disease progression in patient-matched biopsies taken at different timepoints. In addition, TF expression in patient-matched primary tumor and metastatic lesions was also analyzed.

METHODS AND RESULTS

TF expression was detected via immunohistochemistry (IHC) using a validated TF-specific antibody. TF was expressed in all cancer types tested, with highest prevalence in pancreatic cancer, cervical cancer, colon cancer, glioblastoma, HNSCC, and NSCLC, and lowest in breast cancer. Staining was predominantly membranous in pancreatic, cervical, and HNSCC, and cytoplasmic in glioblastoma and bladder cancer. In general, expression was consistent between biopsies obtained from the same patient over time, although variability was observed for individual patients. NSCLC biopsies of primary tumor and matched lymph node metastases showed no clear difference in TF expression overall, although individual patient changes were observed.

CONCLUSION

This study shows that TF is expressed across a broad range of solid cancer types, and expression is present upon tumor dissemination and over the course of treatment.

Tisotumab vedotin in Japanese patients with recurrent/metastatic cervical cancer: results from the innovaTV 206 study

New treatments, particularly second‐line options, are needed to improve outcomes for patients with recurrent/metastatic cervical cancer (r/mCC). Tisotumab vedotin (TV) is an antibody–drug conjugate directed to tissue factor, a transmembrane protein commonly expressed in cancer cells, to deliver cytotoxic monomethyl auristatin E. This single‐arm, open‐label phase 1/2 trial evaluated the consistency of safety and efficacy outcomes of TV in Japanese patients with r/mCC to bridge the current findings with those reported in previous trials in non‐Japanese patients in the United States and Europe. In part 1 (dose escalation; N = 6), patients with advanced solid tumors received TV 1.5 or 2.0 mg/kg once every 3 weeks to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D). Part 2 (dose expansion; N = 17) evaluated the RP2D in r/mCC patients with 1–2 prior lines of therapy. In part 1, no dose‐limiting toxicities were observed, the MTD was not reached, and TV 2.0 mg/kg was established as the RP2D. In part 2, the most common treatment‐emergent adverse events were anemia (58.8%), nausea (58.8%), alopecia (47.1%), epistaxis (47.1%), and diarrhea (35.3%); adverse events of special interest were bleeding (76.5%), ocular events (35.3%), and peripheral neuropathy (17.6%), and were mostly grade 1/2. In part 2, confirmed objective response rate was 29.4%, median duration of response was 7.1 months, and median time to response was 1.2 months. In Japanese patients with r/mCC, TV demonstrated a manageable and tolerable safety, pharmacokinetics, and efficacy profile consistent with that observed in non‐Japanese patients.

Development and Feasibility Testing of the Clinical-Community Linkage Self-Assessment Survey for Community Organizations

Introduction

Clinical-community linkages (CCLs) can improve health, but few instruments exist to evaluate these partnerships. To address this gap, we develop and test the Clinical-Community Linkage Self-Assessment Survey (CCL Self-Assessment).

Materials and Methods

We built on an existing framework and conducted a literature review to guide the design of our survey, and obtained feedback from academic, clinical, and community-based experts. To pretest the instrument, we conducted 10 think-aloud interviews with community-based health-promotion organizations. We performed feasibility testing with 38 staff from 20 community organizations, followed by criterion-validity testing.

Results

The 15-item final instrument includes five domains: Nature of the Relationship, Communication, Referral Process, Feedback Loop, and Timeliness. Expert feedback included keeping the CCL Self-Assessment brief and actionable. Think-aloud interviews produced a range of revisions related to item wording, instructions, brevity, and formatting. Feasibility testing showed high response rate and ease of administration. Sites scoring high on the CCL Self-Assessment also scored high on the criterion measure.

Discussion

We demonstrate feasibility, as well as face, content, construct, and criterion validity. Initial results suggest the CCL Self-Assessment survey may be used by community organizations to identify strengths and weaknesses of their linkages. Next steps include additional statistical validation and testing to determine how the CCL Self-Assessment survey works in the field as well as providing specific tools to improve linkages.

Worksite tobacco control - a qualitative study on perspectives from employers and employees at small worksites

BACKGROUND

Evidence-based interventions (EBIs) for tobacco control can be implemented in worksite settings to reduce tobacco use. Small worksites are less likely to adopt tobacco control EBIs than large worksites. The purpose of this qualitative study was to 1) explore factors that impact small employers' decisions to offer tobacco control EBIs, and 2) understand employees' perceptions of tobacco control at small worksites.

METHODS

Working with staff from small worksites (20-250 employees), we analyzed data from 12 semi-structured interviews with employers (via key informants) and four focus groups with employees. We recruited employers and employees through a purchased business list and market research company, respectively. Interview and focus group topics included perceptions of worksite tobacco control; internal and external forces shaping worksite tobacco control implementation; and perceived worksite support for cessation. We conducted thematic data analysis.

RESULTS

Key themes from the employer interviews included: the local environment played an important role in implementation of tobacco control EBIs; tobacco control was perceived as important but not a priority; and tobacco control decisions were driven by worksite culture. Key themes from the employee focus groups included: perceived employer support for tobacco cessation was limited although there was interest from employees; employees who currently used tobacco were stigmatized for their behavior; and incentives and coaching were considered ideal tobacco control EBIs.

CONCLUSIONS

Tobacco control has not been prioritized at small worksites, despite employees welcoming additional cessation support. This study contributes important information on contextual factors and employee preferences that could be targeted to improve tobacco control EBI implementation. Worksites should implement comprehensive tobacco-free policies, minimize stigma when promoting cessation, establish equitable break policies, and involve employees in decision-making related to tobacco control.

Pathways to Employee Outcomes in a Workplace Health Promotion Program

PURPOSE

This study examined the relationship between employee outcomes and employer implementation of evidence-based interventions (EBIs) for chronic disease prevention.

DESIGN

Cross-sectional samples collected at 3 time points in a cluster-randomized, controlled trial of a workplace health promotion program to promote 12 EBIs.

SETTING

King County, WA.

SAMPLE

Employees of 63 small, low-wage workplaces.

MEASURES

Employer EBI implementation; 3 types of employee outcomes: perceived implementation of EBIs; perceived employer support for health; and health-related behaviors, perceived stress, depression risk, and presenteeism.

ANALYSIS

Intent-to-treat and correlation analyses using generalized estimating equations. We tested bivariate associations along potential paths from EBI implementation, through perceived EBI implementation and perceived support for health, to several employee health-related outcomes.

RESULTS

The intent-to-treat analysis found similar employee health-related behaviors in intervention and control workplaces at 15 and 24 months. Workplaces implemented varying combinations of EBIs, however, and bivariate associations were significant for 4 of the 6 indicators of physical activity and healthy eating, as well as perceived stress, depression risk, and presenteeism. We did not find significant positive associations for cancer screening and tobacco cessation.

CONCLUSION

Our findings support broader dissemination of EBIs for physical activity and healthy eating, as well as more focus on improving employer support for employee health. They also suggest we need better interventions for cancer screening and tobacco cessation.

Clinical-community linkages as a strategy for increasing evidence-based program reach: Results of the PT-REFER randomized controlled trial with older adults and YMCA associations

Background

Most older adults do not meet recommended guidelines for physical activity. Referrals from physical therapists (PTs) to community- and evidence-based physical-activity programs like Enhance®Fitness have potential to address this gap. We tested an intervention intended to increase referrals of older adults to Enhance®Fitness programs offered at YMCAs.

Materials and methods

We developed a capacity-building intervention that included a structured toolkit and technical-assistance calls. From April 2016 to September 2018, using stratified randomization, we conducted a trial with 20 YMCA Associations randomized into intervention and control arms. The primary outcome was the number of new Enhance®Fitness enrollees during the trial period. Using both quantitative and qualitative methods, we also conducted process and intermediate-outcome evaluations to assess intervention implementation and Association outreach activities, barriers, and facilitators.

Results

The intervention was implemented as intended, but PT outreach was similar for both intervention and control YMCA Associations. The intervention arm had similar enrollment (1695 new enrollees) to the control arm (1326 new enrollees; 95% confidence interval, −47%–199%, P = 0.61). Interviews revealed that barriers, including lack of staff and time for outreach, limited capacity for Enhance®Fitness program growth, and competing priorities, outweighed facilitators, including existing partnerships, presence of an outreach team, senior leadership support, and infrastructure for referrals.

Conclusions

YMCA Associations in the intervention arm were unable to increase their outreach to PTs and enrollment in Enhance®Fitness. Our evaluation findings indicate that community organizations that prioritize program growth, have support at all organizational levels, and allocate staff and time for outreach and partnership development may be more successful in creating sustainable linkages with clinical partners and increasing evidence-based-program reach.

•

Physical therapists (PTs) may help older adults increase their physical activity by referring them to physical-activity programs.

•

In a randomized trial, we helped YMCA Associations build capacity to increase referrals by PTs of older adults to YMCA Enhance®Fitness programs.

•

The YMCA Associations encountered barriers and were unable to increase PT outreach and Enhance®Fitness enrollment.

•

We did, however, identify facilitators that may help community organizations create linkages with clinical partners and increase program reach.

•

Facilitators include prioritizing program growth, having senior-leadership support, and setting aside staff and time for outreach.

By the Seat of Our Pants: the Experience of Small Businesses in the COVID-19 Pandemic, Washington State, March–October 2020

Introduction

Most US businesses are small, yet they employ almost half of the nation’s workforce. Literature is limited about how small employers (those with 20–250 employees) have made decisions about operating their businesses during the COVID-19 pandemic. We sought to learn how employers made these decisions, what information sources they used, what information they wanted, and to what extent they worked with or used information from their local health department.

Methods

We conducted qualitative, semistructured interviews with 26 employers in Washington State, from August through October 2020. Employers were recruited from 7 counties (4 urban and 3 rural) that were experiencing either higher or lower COVID-19 case rates than Washington State overall.

Results

Employers relied heavily on national government resources to make decisions about how to operate their businesses during the COVID-19 pandemic. Few employers had relationships with or turned to their local health departments for information or support. Employers wanted information about COVID-19 safety that was specific to their business operations and industry. Employers also described the emotional toll of COVID-19 and the challenge of trying to make high-stakes decisions with rapidly evolving information.

Conclusion

Small employers showed little awareness of their local health departments and the information and assistance they could provide. Local health departments could increase their visibility and build relationships with small employers by partnering with them on value-added services such as workplace health promotion. Establishing these relationships could support more rapid collaboration between local health departments and small employers during future public health crises.

Partnerships to expand worksite wellness programs - A qualitative analysis of state and local health department perspectives

Chronic diseases such as heart disease, cancer, and diabetes are the leading causes of death and disability in the U. S. Because the central mission of state and local health departments (HDs) is to protect, promote, and improve population health, these agencies are well-positioned to address risk behaviors for chronic disease. HD-employer partnerships could enhance worksite wellness programming, but few studies have explored this topic. Building upon previously published findings, the purpose of this qualitative study was to describe the context and environment for HDs' delivery of worksite wellness programs, including interest, barriers, facilitators, and decision-making processes. We conducted 12 interviews with directors of state chronic disease programs, 21 interviews with local directors, and three focus groups with local staff. We performed a thematic analysis of the data. Key themes include the following: (1) worksite wellness programs delivered by HDs were diverse in topic and scope and delivered both internally (at the HD for their agency) and externally (for other employers); (2) decisions made about chronic disease prevention were largely driven by funding priorities, with federal, state, and local entities playing roles in the decision-making process; and (3) HDs expressed potential interest in worksite wellness program delivery, dependent upon staff capacity, available funding, and employer buy-in. Our results suggest that funding should be increased for and reallocated towards chronic disease prevention, including worksite wellness. To overcome HD barriers to program delivery, key funders and stakeholders should prioritize and communicate the importance of worksite wellness.

Clinical diagnostic utility of ultrasound-guided fine needle aspiration biopsy in parotid masses

BACKGROUND

Fine needle aspiration (FNA) is a common diagnostic tool used in the initial evaluation of parotid masses. In the literature, variable diagnostic accuracy of FNA is reported. Therefore, when considering clinical management of these patients, the utility of FNA is unclear. The aim of this study was to determine the capability of ultrasound-guided FNA to differentiate between benign and malignant neoplasms. Further, the way in which FNA results affect clinical decision-making was assessed.

METHODS

Retrospective data were collected for all patients who underwent parotidectomy at a large Canadian tertiary care center between 2011 and 2016. Patient demographics, preoperative imaging reports, preoperative FNA results, and final pathological diagnosis were analyzed.

RESULTS

Of the 199 patients who underwent parotidectomy, 184 had preoperative ultrasound-guided FNA. There were a total of 13 non-diagnostic FNAs. In diagnosing malignancy, FNA had a sensitivity and specificity of 71.4% and 98.7%, respectively. The positive predictive value (PPV) was 83.3%. The negative predictive value was 97.5%. Of the non-diagnostic FNAs, 2 out of 13 (15.4%) were deemed malignant neoplasms on final pathology.

CONCLUSION

FNA is a useful adjunct in the work-up of parotid masses, but it should be used with caution. Due to limited sensitivity, it should not be relied upon as the sole determinant of a surgeon's management plan.

Local Health Departments' Capacity for Workplace Health Promotion Programs to Prevent Chronic Disease: Comparison of Rural, Micropolitan, and Urban Contexts

OBJECTIVE

To examine local health department (LHD) contexts, capacity for, and interest in partnering with employers on workplace health promotion programs (WHPPs) for chronic disease prevention.

DESIGN

Qualitative interviews with LHD directors.

SETTING

LHDs from 21 counties in 10 states.

PARTICIPANTS

Twenty-one LHD directors.

MAIN OUTCOME MEASURESS

Experiences and perceptions of existing partnerships, decision making, funding, data needs, and organizational capacity for WHPP partnerships with employers.

RESULTS

We identified 3 themes: (1) LHDs see the value of partnering with employers but lack the capacity to do so effectively; (2) while LHDs base priorities on community need, funding ultimately drives decision making; and (3) rural, micropolitan, and urban LHDs differ in their readiness and capacity to work with employers.

CONCLUSIONS

Understanding LHDs' partnership capacity and context is essential to the successful implementation of WHPP partnerships with employers. Expanding these partnerships may require additional financial investments, particularly among rural LHDs.

Development and Pilot Test of an Online Training to Engage Managers to Support Workplace Wellness

OBJECTIVE

To contribute to a broader understanding of effective implementation strategies to help managers engage employees in workplace wellness.

METHODS

We beta-tested an online training at four Washington state agencies (two test, two control). We administered a post-training evaluation, re-administered an online manager survey and conducted additional interviews with wellness leads.

RESULTS

Training participation rate was high. The two test agencies experienced a significant increase in the percentage of managers who: agreed that they received training on employee wellness; agreed their agency's culture supports employee wellness; and encouraged their employees to participate in wellness activities. Approximately 80% of managers who received the training agreed they could apply information learned to support employee wellness.

CONCLUSIONS

If proven effective, the training could be administered at a low cost and disseminated to improve employee health.

Local Health Jurisdiction Staff Deliver Health Promotion to Small Worksites, Washington

CONTEXT

Worksites can serve as community sites for local health jurisdictions (LHJs) to assist with implementation of evidence-based interventions (EBIs) to prevent and control chronic diseases.

OBJECTIVE

To assess the feasibility and effectiveness of using LHJ staff to disseminate Connect to Wellness (CtW), an effective dissemination package for increasing implementation of EBIs for chronic disease control by small worksites.

DESIGN

Single-arm, multisite intervention trial, with measurement at baseline, after 6 months of intervention, and after a maintenance period of 6 months.

SETTING

Six geographically dispersed counties in Washington State. Target worksites had 20 to 250 employees.

PARTICIPANTS

Nine staff members from 6 LHJs delivered CtW to 35 worksites.

INTERVENTION

Connect to Wellness seeks to increase worksites' implementation of 14 EBIs classified as communication, policy, or program approaches to increasing 4 behaviors: cancer screening, healthy eating, physical activity, and tobacco cessation.

MAIN OUTCOME MEASURE

Evidence-based intervention implementation measured on a scale from 0% to 100%.

RESULTS

Participating worksites showed a significant increase (P < .001, t test) in total mean implementation scores from baseline (33%) to 6-month follow-up (47%). Increases in implementation for communications, policy, healthy eating, and tobacco EBIs were statistically significant at 6 months and maintained at 12 months. Increased implementation at 6 months of a group physical activity program was not sustained after the program became unavailable, and total implementation scores at 12 months (38%) showed little change from baseline.

CONCLUSIONS

Local health jurisdiction-delivered CtW increased worksites' implementation of EBIs at 6 months, and increased implementation in communication, policy, healthy eating, and tobacco was maintained at 12 months. This package, delivered by LHJ staff working part-time on CtW, was nearly as successful as prior delivery by staff working full-time on CtW.

Relationship of depth of invasion to survival outcomes and patterns of recurrence for T3 oral tongue squamous cell carcinoma

INTRODUCTION

Current research is elucidating how the addition of depth of invasion (DOI) to the 8th edition of the American Joint Committee on Cancer (AJCC) TNM staging for oral cavity squamous cell carcinoma influences its prognostic accuracy. However, there is limited research on survival in pT3N0M0 oral tongue SCC (OTSCC) patients when stratifying by DOI.

OBJECTIVES

Determine 5-year overall survival (OS), and cancer-specific survival (CSS) for patients with pT3N0M0 oral OTSCC based on shallow DOI (<10 mm) and deep DOI (10-20 mm).

METHODS

Retrospective review involving three tertiary care cancer centers in North America. cT3N0M0 OTSCC patients receiving primary surgical treatment from 2004 to 2018 were identified. Inclusion: age > 18 years old and confirmation of pT3N0M0 OTSCC on surgical pathology. Exclusion: patients undergoing palliative treatment or previous head and neck surgery/radiotherapy. Analysis comprised two groups: shallow pT3 (tumor diameter > 4 cm, DOI < 10 mm) and deep pT3 (DOI 10 mm-20 mm).

RESULTS

One hundred and four patients with pT3N0M0 OTSCC were included. Mean age was 59.1 years (range: 18-80.74). Age, gender, and Charlson Comorbidity Index were similar between the two groups (p > 0.05). Recurrence, LVI, PNI, and positive margins were more common in deep T3 tumors (P < 0.05). 5-year OS (50% vs 26%, p = 0.006) and CSS (72% vs 24%, p = 0.005) were worse in deep pT3 tumors. Deep pT3 disease was an independent predictor of OS (p = 0.004) and CSS (p = 0.01) on Cox-Regression analysis.

CONCLUSION

DOI is an independent predictor of poor survival in pT3N0M0 OTSCC patients. Consideration should be given to escalating adjuvant therapy for deep pT3N0M0 OTSCC patients.

Using a Social Capital Framework to Explore a Broker's Role in Small Employer Wellness Program Uptake and Implementation

PURPOSE

Small employers, while motivated to implement wellness programs, often lack knowledge and resources to do so. As a result, these firms rely on external decision-making support from insurance brokers. The objective of this study was to analyze brokers' familiarity with wellness programs and to characterize their role and interactions with small employers.

DESIGN

Using a newly developed common interview guide (20 questions), protocol and analysis plan, 20 interviews were conducted with health insurance brokers in Illinois, Minnesota, North Carolina and Washington in 2016 and 2017. In addition to exploring patterns of broker interactions and familiarity by segment, we propose a framework to conceptualize the broker-client relationship using social capital theory and the RE-AIM model.

METHODS

Interviews were transcribed, summarized and a common codebook was established using DeDoose. Themes were identified following multi-rater coding and structured within the framework.

RESULTS

Participating brokers reported having a high to moderate familiarity with wellness programs (65%) and a majority (80%) indicated that they have previously advised their small business clients on the availability and features of them. Further, we find that brokers may help eliminate barriers to resources and act as a connector to wellness opportunities within their professional network.

CONCLUSION

New initiatives to promote small employer wellness programs can benefit from examining the influence of brokers on the decision-making process. When engaged and supported with resources, brokers may be effective champions for employer wellness programs.

The Workplace Support for Health Scale: Reliability and Validity of a Brief Scale to Measure Employee Perceptions of Wellness

PURPOSE

To examine the reliability and validity of a brief measure (the Workplace Support for Health [WSH] scale) to assess employees' perceived support for a healthy lifestyle.

DESIGN

Repeated cross-sectional surveys.

SETTING

We collected employer- and employee-level survey data from small, low-wage workplaces in King County, WA enrolled in a randomized controlled trial.

SAMPLE

We analyzed data from 68 workplaces that had 2,820 and 2,640 employees complete surveys at baseline and 15 months, respectively.

MEASURES

The WSH scale consisted of five items. To assess validity, we examined associations between the WSH scale and employer implementation of evidence-based interventions for health promotion, employee self-rated health, and job satisfaction.

ANALYSIS

We performed an exploratory factor analysis to assess the unidimensionality of the WSH scale items, and produced Cronbach's alpha coefficients to examine scale reliability. We ran regression models using generalized estimating equations to examine validity.

RESULTS

The factor analysis indicated one factor, which accounted for 59% of the total variance in the workplace support for health items. The scale had good reliability at baseline (α = 0.82) and 15 months (α = 0.83). Employer evidence-based intervention implementation was positively associated with WSH. WSH was also associated with higher self-rated health and job satisfaction. These associations indicate good concurrent validity.

CONCLUSION

The WSH scale is a reliable and valid measure of perceived workplace support for health. Employers can use the scale to identify gaps in support and create a plan for improvement.

Predictors of Improvement in Physical Function in Older Adults in an Evidence-Based Physical Activity Program (EnhanceFitness)

BACKGROUND AND PURPOSE

Declines in strength, flexibility, and balance in older adults can lead to injuries and loss of independence and are particularly common in those of greater age and in worse health. EnhanceFitness (EF) is a nationally disseminated, evidence-based group exercise program for older adults that has been shown to improve function through cardiovascular, strength, flexibility, and balance exercises. This article examines changes in, and predictors of, participant physical function from baseline through 2 program cycles of EF as measured by 3 physical function tests: arm curls, chair stands, and 8-foot up-and-go.

METHODS

We analyzed data on participants who attended at least 2 consecutive 16-week program cycles between January 2005 and June 2016. We ran 3 random-effects linear regression models, 1 for each physical function test, and accounted for missing data and clustering by class site. Independent variables included attendance, demographics, and health status.

RESULTS AND DISCUSSION

A total of 7483 participants completed baseline and 2 sets of follow-up physical function tests. For all 3 physical function tests, participants showed some degree of improved physical function at each follow-up, and greater program attendance predicted clinically significant improvements. Some participants had less improvement: females, those less active at baseline, older than 75 years, not married or partnered, or in fair or poor health, those who had experienced at least 1 fall, and those with a disability.

CONCLUSION

EnhanceFitness program providers may need to implement additional measures to support the participants who could benefit most from EF, such as targeting messaging, coordinating with referring providers to emphasize attendance and general activity in specific participants, and offering additional support to groups who show less improvement during classes. The evidence presented here may inform clinical decision making for older adult patients and increase health care provider confidence in EF and similar exercise programs, thereby providing a mechanism to maintain and continue functional gains made in clinical or rehabilitation settings.

Development of a Wellness Committee Implementation Index for Workplace Health Promotion Programs in Small Businesses

PURPOSE

To construct a wellness committee (WC) implementation index and determine whether this index was associated with evidence-based intervention implementation in a workplace health promotion program.

DESIGN

Secondary data analysis of the HealthLinks randomized controlled trial.

SETTING

Small businesses assigned to the HealthLinks plus WC study arm.

SAMPLE

Small businesses (20-200 employees, n = 23) from 6 low-wage industries in King County, Washington.

MEASURES

Wellness committee implementation index (0%-100%) and evidence-based intervention implementation (0%-100%).

ANALYSIS

We used descriptive and bivariate statistics to describe worksites' organizational characteristics. For the primary analyses, we used generalized estimating equations with robust standard errors to assess the association between WC implementation index and evidence-based intervention implementation over time.

RESULTS

Average WC implementation index scores were 60% at 15 months and 38% at 24 months. Evidence-based intervention scores among worksites with WCs were 27% points higher at 15 months (64% vs 37%, P < .001) and 36% points higher at 24 months (55% vs 18%, P < .001). Higher WC implementation index scores were positively associated with evidence-based intervention implementation scores over time (P < .001).

CONCLUSION

Wellness committees may play an essential role in supporting evidence-based intervention implementation among small businesses. Furthermore, the degree to which these WCs are engaged and have leadership support, a set plan or goals, and multilevel participation may influence evidence-based intervention implementation and maintenance over time.

Development of a Patient-Centered Functional Outcomes Questionnaire in Head and Neck Cancer

Importance

Incorporation of patient perspectives, or patient-reported outcomes, in functional outcome measures has been gaining prominence in the literature on reconstructive surgery.

Objective

To create and validate an instrument for measuring the main functional areas of concern for patients with head and neck cancer.

Design, Setting, and Participants

This 4-phase mixed-methods qualitative study was conducted from July 1, 2013, to June 30, 2016, in a quaternary head and neck oncology center in Edmonton, Alberta, Canada. Patients were recruited from 3 Head and Neck Research Network sites: University of Alberta (Edmonton, Canada), Mount Sinai Health Network (New York, New York), and University of Turku Hospital (Turku, Finland). The inclusion criteria included 18 years of age or older, diagnosis of squamous cell carcinoma involving the subsites of the head and neck (ie, oral cavity, oropharynx, hypopharynx, and larynx), and at least 1 year since treatment completion. Those patients who were undergoing additional active treatment or with evidence of disease recurrence were excluded. Data were analyzed from July 1, 2013, to June 30, 2016.

Main Outcomes and Measures

The primary outcome measures were the clinical correlation of the Edmonton-33 instrument scores with swallowing, speech, dry mouth, and chewing assessment outcomes.

Results

In total, 10 patients with head and neck cancer (mean age, 59.6 years; 6 men [60%]) were included in phase 1 of the study, 5 patients (mean age, 55.2 years) were included in phase 2, 10 patients were included in phase 3, and 25 patients with head and neck cancer (mean age, 62.6 years; 14 men [56%]) participated in the phase 4 validation. The Edmonton-33 instrument scores correlated strongly with the swallowing scores of the MD Anderson Dysphagia Inventory (r = 0.77; 95% CI, 0.49-1.0), the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Head and Neck 35 (EORTC QLQ-H&N35) (r = -0.73; 95% CI, -1.0 to -0.44), and the modified barium swallow test (r = -0.60; 95% CI, -0.94 to -0.25). The instrument scores were also strongly correlated with the Speech Handicap Index scores (r = -0.64; 95% CI, -0.97 to -0.31), word intelligibility scores (r = 0.61; 95% CI, 0.27-0.95), and sentence intelligibility scores (r = 0.55; 95% CI, 0.19-0.91). A moderate to strong correlation was observed between the Edmonton-33 instrument and the EORTC QLQ-H&N35 scores in the dry mouth (r = -0.54; 95% CI, -0.91 to -0.18) and chewing (r = -0.45; 95% CI, -0.84 to -0.06) domains. The factor loading values for the domains of swallowing, speech, dry mouth, and chewing were all greater than 0.3. The mean factor loading values for the items related to swallowing were 0.71 (95% CI, 0.62-0.80) and for the items related to speech were 0.76 (95% CI, 0.72-0.80). The mean factor loading values for the items related to dry mouth were 0.71 (95% CI, 0.59-0.83) and for those related to chewing were 0.77 (95% CI, 0.69-0.85).

Conclusions and Relevance

The Edmonton-33 appears to be a validated instrument that will allow patients with head and neck cancer to assess and report their own functional outcomes. It could serve as a single comprehensive measure for functional outcomes.

Washington's privatization of liquor: effects on household alcohol purchases from Initiative 1183

BACKGROUND AND AIMS

Washington Initiative 1183 (I-1183), a 2012 law that privatized liquor retail sales and distribution in Washington State, USA, has had two opposing effects on liquor purchases: it has increased access to liquor and imposed new fees on retailers and distributors. This study aimed to estimate the effect of I-1183 on monthly alcohol purchases during the post-I-1183 period (June 2012-December 2014) compared with the pre-I-1183 period (January 2010-May 2012).

DESIGN

DIFFERENCES-IN-DIFFERENCES STUDY: Setting and participants The study included households participating in the Nielsen Consumer Panel Dataset living in metropolitan and surrounding areas in Washington State and 10 control states. Measurements Outcomes were alcohol purchases by type (ounces of liquor, wine, beer and total alcohol or ethanol). Findings I-1183 was associated with a 6.34-ounce (P < 0.001) and a 2.01-ounce (P < 0.001) increase in monthly liquor and ethanol purchases, respectively, per household in the post-policy period spanning 31 months compared with monthly purchases in control states. In a longitudinal subgroup analysis, low and moderate alcohol purchasers increased monthly purchases of ethanol and high purchasers decreased purchases of ethanol. Conclusions Enacting 'Washington Initiative 1183', a law that privatized sale and distribution of liquor and imposed new fees on retailers and distributors, appears to have been associated with an approximate 82% increase in monthly liquor purchases and 26% increase in monthly ethanol purchases by households in metropolitan and surrounding areas in Washington State, USA.

Tisotumab Vedotin in Previously Treated Recurrent or Metastatic Cervical Cancer

PURPOSE

Tissue factor (TF) is a potential target in cervical cancer, as it is frequently highly expressed and associated with poor prognosis. Tisotumab vedotin, a first-in-class investigational antibody-drug conjugate targeting TF, has demonstrated encouraging activity in solid tumors. Here we report data from the cervical cancer cohort of innovaTV 201 phase I/II study (NCT02001623).

PATIENTS AND METHODS

Patients with recurrent or metastatic cervical cancer received tisotumab vedotin 2.0 mg/kg every 3 weeks until progressive disease, unacceptable toxicity, or consent withdrawal. The primary objective was safety and tolerability. Secondary objectives included antitumor activity.

RESULTS

Of the 55 patients, 51% had received ≥2 prior lines of treatment in the recurrent or metastatic setting; 67% had prior bevacizumab + doublet chemotherapy. Fifty-one percent of patients had squamous cell carcinoma. The most common grade 3/4 treatment-emergent adverse events (AEs) were anemia (11%), fatigue (9%), and vomiting (7%). No grade 5 treatment-related AEs occurred. Investigator-assessed confirmed objective response rate (ORR) was 24% [95% confidence interval (CI): 13%-37%]. Median duration of response (DOR) was 4.2 months (range: 1.0+-9.7); four patients responded for >8 months. The 6-month progression-free survival (PFS) rate was 29% (95% CI: 17%-43%). Independent review outcomes were comparable, with confirmed ORR of 22% (95% CI: 12%-35%), median DOR of 6.0 months (range: 1.0+-9.7), and 6-month PFS rate of 40% (95% CI: 24%-55%). Tissue factor expression was confirmed in most patients; no significant association with response was observed.

CONCLUSIONS

Tisotumab vedotin demonstrated a manageable safety profile and encouraging antitumor activity in patients with previously treated recurrent or metastatic cervical cancer.

Use of Cigarettes and E-Cigarettes and Dual Use Among Adult Employees in the US Workplace

Introduction

Evidence-based interventions for tobacco control in the US workplace can reach a large audience. The purpose of our study was to explore the prevalence and determinants of type of tobacco use (ie, cigarettes only, e-cigarettes only, or dual use) among adult employees in the United States and to examine type of use by state.

Methods

We used data from the 2017 Behavioral Risk Factor Surveillance System to examine the prevalence of cigarette use, e-cigarette use, dual use, and quit attempts. We used multinomial logistic regression to examine the relationships between sociodemographic characteristics and type of tobacco product used, and we estimated adjusted prevalence.

Results

Approximately 17% of respondents were current smokers, 5% were current e-cigarette users, and 2% were dual users. E-cigarette-only and dual use were generally highest among young (aged 18–24), male, and less-educated respondents and lower for respondents who identified as black, Asian/Native Hawaiian/Pacific Islander, or Hispanic than for white respondents. Cigarette-only and dual use were higher for respondents who did not have health care coverage. Prevalence by state of e-cigarette use only ranged from 1.2% (Vermont) to 3.9% (Arkansas), whereas the prevalence of dual use ranged from 0.6% (District of Columbia) to 4.0% (Oklahoma).

Conclusion

Prevalence of cigarette, e-cigarette, and dual use varied by sociodemographic characteristics and by state. These findings can support targeting of specific populations when designing and implementing evidence-based interventions for tobacco control in workplace settings.

Disseminating Evidence-Based Interventions in Small, Low-Wage Worksites: A Randomized Controlled Trial in King County, Washington (2014-2017)

Objectives. To determine whether (1) participating in HealthLinks, and (2) adding wellness committees to HealthLinks increases worksites' evidence-based intervention (EBI) implementation.Methods. We developed HealthLinks to disseminate EBIs to small, low-wage worksites. From 2014 to 2017, we conducted a site-randomized trial in King County, Washington, with 68 small worksites (20-200 employees). We assigned worksites to 1 of 3 arms: HealthLinks, HealthLinks plus wellness committee (HealthLinks+), or delayed control. At baseline, 15 months, and 24 months, we assessed worksites' EBI implementation on a 0% to 100% scale and employees' perceived support for their health behaviors.Results. Postintervention EBI scores in both intervention arms (HealthLinks and HealthLinks+) were significantly higher than in the control arm at 15 months (51%, 51%, and 23%, respectively) and at 24 months (33%, 37%, and 24%, respectively; P < .001). Employees in the intervention arms perceived greater support for their health at 15 and 24 months than did employees in control worksites.Conclusions. HealthLinks is an effective strategy for disseminating EBIs to small worksites in low-wage industries.Public Health Implications. Future research should focus on scaling up HealthLinks, improving EBI maintenance, and measuring impact of these on health behavior.

Abstract 221: Tisotumab vedotin induces anti-tumor activity through MMAE-mediated, Fc-mediated, and Fab-mediated effector functions in vitro

Tisotumab vedotin is an antibody-drug conjugate composed of a human IgG targeting tissue factor (TF), a valine citruline linker, and the microtubule disrupting agent monomethyl auristatin E (MMAE). TF is aberrantly expressed in solid tumors and is thought to contribute to tumor progression by enhancing tumor growth, neo-angiogenesis and metastatic potential through local activation of coagulation and protease-activated receptor-2 (PAR-2) signaling. Tisotumab vedotin was previously shown to induce cytotoxicity through MMAE- and Fc-dependent mechanisms. In addition, tisotumab vedotin inhibited PAR-2 signaling in TF-positive tumor cells. Here we aimed to elucidate additional effector mechanisms by assessing the capacity of tisotumab vedotin to induce immunogenic cell death (ICD), bystander cytotoxicity, and antibody-dependent cellular phagocytosis (ADCP) in vitro. ICD was assessed by incubating A431, MDA-MB-231, and HPAFII cells with tisotumab vedotin, and measuring ER stress by western blot, ATP secretion by reporter assay, and HMGB1 release by ELISA. Bystander cytotoxicity was assessed by incubating mixed cultures of TF+ (MDA-MB-231) and TF- (A549) tumor cells with tisotumab vedotin and quantifying viable cells by flow cytometry. To assess ADCP, PKH26-labeled BxPC-3 or A431 cells were incubated with human monocyte derived macrophages in presence of tisotumab vedotin. ADCP activity was analyzed by measuring the fraction of macrophages that double stained with PKH26 and anti-CD11c antibody using flow cytometry. Tisotumab vedotin induced key hallmarks of ICD including induction of ER stress, ATP secretion, and release of HMGB1, which have been shown to facilitate antitumor immunity. In co-cultures of TF+ and TF- tumor cells, tisotumab vedotin induced cytotoxicity in both cell types, even at a target-positive to target-negative cellular ratio of 1:15. This was mediated through bystander cytotoxicity, as demonstrated by the lack of cytotoxicity in monocultures of TF- cells. Finally, ADCP was observed with macrophages derived from multiple donors, with double-positive macrophages comprising up to 50% of total macrophages. In summary, ICD, bystander cytotoxicity, and ADCP were identified as novel effector mechanisms of tisotumab vedotin in vitro. Combining the present study with previous results, tisotumab vedotin induces TF-dependent anti-tumor activity through 1) MMAE-mediated effector mechanisms, including MMAE-mediated direct and bystander cytotoxicity, and induction of ICD; 2) Fc-mediated effector mechanisms, including ADCC and ADCP; and 3) Fab-mediated inhibition of PAR-2 dependent signaling. Tisotumab vedotin is currently being investigated in a variety of solid tumors (NCT03245736, NCT03485209, NCT03438396, NCT03657043).

Provider-Patient Communication and Involvement in Physical Activity Programs Among Patients Receiving Physical Therapy Services: A Qualitative Study

Objectives: To describe how physical therapy providers and their patients interact and communicate about physical activity (PA), and explore the barriers and facilitators to patient involvement in PA programs. Method: We conducted 39 direct observations of patient visits with physical therapy providers and 30 telephone interviews with physical therapists (PTs). We conducted a thematic analysis of observation field notes and interview transcripts. Results: PTs and patients engaged in several behaviors to build rapport, discussed PA type and frequency, and exchanged advice and information about PA. Barriers to patient participation in PA programs included low instrumental support, physical limitations, lack of motivation and confidence, and lack of knowledge about available programs. Facilitators included emotional support from friends, peers, and family, and encouragement and information-sharing from providers. Discussion: PTs play an important role in improving older adult PA and could be instrumental in reducing barriers to PA participation.

Is Maternal Income in Childhood Associated With Adolescent Health and Behavioral Outcomes?

Maternal income increases immediate investment in children for food, child care, and health care, but whether maternal income influences longer term health and behavioral outcomes is unknown. Using data from the NICHD Study of Early Child Care and Youth Development, we examine the association between maternal income in early and later childhood on body mass index percentile, problem behaviors, and self-reported health status at age 15 among a sample of children (N = 1,283) whose mothers were employed at at least one observation time point between birth and age 15 (1991-2005). When controlling for family income (minus maternal income) and maternal employment characteristics, higher maternal income during early childhood was significantly associated with fewer adolescent problem behaviors. Maternal income during early childhood may influence adolescent behavioral outcomes. These findings suggest that increased maternal income, a positive externality of maternal employment, may increase the net benefit of maternal employment for child behavior.

Building community-clinical linkages to increase older adult physical activity: The PT-REFER trial protocol and participant baseline characteristics

Background

Physical activity is important for maintaining older adult health, but a majority of older adults are not meeting recommended physical activity levels. This paper describes the protocol and participant baseline characteristics for a trial (named "PT-REFER") to test an intervention focused on developing community-clinical linkages to increase older adult referrals from physical therapy clinics to an evidence-based group exercise program (Enhance®Fitness) (EF) offered by YMCA associations.

Methods

We designed a two-arm cluster-randomized controlled trial with YMCA associations. We conducted formative research with YMCA staff and physical therapists to inform intervention format and content. The primary outcome is the number of new participants enrolled in EF over the course of 30 months. We also collect process information on cost and implementation though structured surveys and semi-structured qualitative interviews.

Results

The PT-REFER intervention creates a learning collaborative for YMCA associations, which are tasked with implementing a number of capacity- and partnership-building activities over the course of seven months, and participating in monthly group technical assistance calls. We recruited 20 YMCA associations from 13 states. At baseline, the average number of EF sites per association was 3.9 and the monthly average number of new EF participants was 3.7.

Conclusions

This study will test an approach to increasing the capacity of YMCAs for conducting outreach to physical therapy clinics, and evaluate the factors that may influence its implementation. As a result, it has the potential to contribute to our understanding of how to develop viable and sustainable community-clinical linkages for older adult health.

The association of Bcl-xL and p53 expression with survival outcomes in oropharyngeal cancer

BACKGROUND

The role of molecular biomarkers in oropharyngeal squamous cell carcinoma (OPSCC) has recently been increasingly recognized. There is conflicting evidence in the literature with regards to the prognostic value of p53 and Bcl-xL.

OBJECTIVE

The purpose of this study was to investigate the association between p53 and Bcl-xL expression profiles and survival outcomes in OPSCC.

METHODS

Patients diagnosed with OPSCC and treated with curative intent between 1998 and 2009 were included in the study. Patient demographics, disease, treatment, and oncologic outcomes were collected prospectively. A tissue microarray (TMA) from patients' biopsies or surgical specimens was retrospectively constructed. The expression levels of p53, Bcl-xL, and p16 were digitally quantified and correlated to patient survival outcomes.

RESULTS

One hundred and sixty-six patients were included (mean age 56.7 years; standard deviation (SD) ± 10.0; 78% male). High expression of Bcl-xL (p= 0.04) was significantly associated with nodal disease at presentation, and decreased overall survival (OS) (p= 0.04). Combined expression of low Bcl-xL and low p53 conferred a survival advantage in non-smokers (p= 0.04). Multivariate analysis supported smoking and p16 status as independent prognosticators for OS.

CONCLUSIONS

This study suggests that biomarker profiling using Bcl-xL and p53 levels may be of prognostic value in select patients with OPSCC.

Validation of a novel method for localization of parathyroid adenomas using SPECT/CT

Background

Accurate localization of parathyroid adenomas is of critical importance in surgical planning for minimally invasive parathyroidectomy. SPECT/CT is considered the investigation of choice but has limitations regarding localization of superior versus inferior adenomas. We proposed a novel method for localization using SPECT/CT by determining the anterior-posterior relationship of the adenoma to a horizontal line in the coronal plane through the tracheoesophageal groove. Our objective was to determine the accuracy, validity, and inter-rater reliability of this method.

Method

This was a retrospective review of patients who underwent parathyroidectomy for a single adenoma between 2010-2017. SPECT/CT images were reviewed by two staff Otolaryngologists, a Radiologist, an Otolaryngology fellow and Otolaryngology resident. Results were compared using intra-operative report as the gold standard.

Overall accuracy in determining superior/inferior and right/left adenomas was calculated, as well as Cohen's Kappa to determine agreement with operative report and inter-rater reliability. The performance was compared to that of the original radiology report.

Results

One hundred thirty patients met criteria and were included. Our method correctly identified the location of the adenoma in terms of both side and superior/inferior position in 80.4% [76 - 84%] of patients, which considerably outperformed the original radiology report at 48.5% [4-78%] accuracy. The agreement level between our method and operative report was high (Kappa=0.717 [0.691-0.743]), as was the inter-rater reliability (Kappa=0.706 [0.674-0.738]).

Conclusion

We report a novel method for localization of parathyroid adenomas using SPECT/CT which outperforms standard radiology reporting. This tool can be used by surgeons and radiologists to better inform and plan for minimally invasive parathyroidectomy.

Associations between birth size and later height from infancy through adulthood: An individual based pooled analysis of 28 twin cohorts participating in the CODATwins project

BACKGROUND

There is evidence that birth size is positively associated with height in later life, but it remains unclear whether this is explained by genetic factors or the intrauterine environment.

AIM

To analyze the associations of birth weight, length and ponderal index with height from infancy through adulthood within mono- and dizygotic twin pairs, which provides insights into the role of genetic and environmental individual-specific factors.

METHODS

This study is based on the data from 28 twin cohorts in 17 countries. The pooled data included 41,852 complete twin pairs (55% monozygotic and 45% same-sex dizygotic) with information on birth weight and a total of 112,409 paired height measurements at ages ranging from 1 to 69 years. Birth length was available for 19,881 complete twin pairs, with a total of 72,692 paired height measurements. The association between birth size and later height was analyzed at both the individual and within-pair level by linear regression analyses.

RESULTS

Within twin pairs, regression coefficients showed that a 1-kg increase in birth weight and a 1-cm increase in birth length were associated with 1.14-4.25 cm and 0.18-0.90 cm taller height, respectively. The magnitude of the associations was generally greater within dizygotic than within monozygotic twin pairs, and this difference between zygosities was more pronounced for birth length.

CONCLUSION

Both genetic and individual-specific environmental factors play a role in the association between birth size and later height from infancy to adulthood, with a larger role for genetics in the association with birth length than with birth weight.

Multi-dimensional analysis of oral cavity and oropharyngeal defects following cancer extirpation surgery, a cadaveric study

BACKGROUND

Defects following resection of tumors in the head and neck region are complex; more detailed and defect-specific reconstruction would likely result in better functional and cosmetic outcomes. The objectives of our study were: 1) to improve the understanding of the two- and three-dimensional nature of oral cavity and oropharyngeal defects following oncological resection and 2) to assess the geometric dimensions and the shapes of fasciocutaneous free flaps and locoregional tissue flaps required for reconstruction of these defects.

METHODS

This study was an anatomic cadaveric study which involved creating defects in the oral cavity and oropharynx in two cadaveric specimens. Specifically, partial and total glossectomies, floor of mouth excisions, and base of tongue excisions were carried out. These subsites were subsequently geometrically analyzed and their volumes measured. The two-dimensional (2D) assessment of these three-dimensional (3D) structures included measures of surface area and assessment of tissue contours and shapes.

RESULTS

The resected specimens all demonstrated unique dimensional geometry for the various anatomic sites. Using 2D analysis, hemiglossectomy defects revealed right triangle geometry, whereas total glossectomy geometry was a square. Finally, the base of tongue defects exhibited a trapezoid shape.

CONCLUSIONS

Customizing the geometry and dimensions of fasciocutaneous free flaps so that they are specific to the confronted head and neck defects will likely result in better functional and cosmetic outcomes.

Readiness to Change Over Time: Change Commitment and Change Efficacy in a Workplace Health-Promotion Trial

Introduction

Organizational readiness to change may be a key determinant of implementation success and a mediator of the effectiveness of implementation interventions. If organizational readiness can be reliably and validly assessed at the outset of a change initiative, it could be used to assess the effectiveness of implementation-support activities by measuring changes in readiness factors over time.

Methods

We analyzed two waves of readiness-to-change survey data collected as part of a three-arm, randomized controlled trial to implement evidence-based health promotion practices in small worksites in low-wage industries. We measured five readiness factors: context (favorable broader conditions); change valence (valuing health promotion); information assessment (demands and resources to implement health promotion); change commitment (an intention to implement health promotion); and change efficacy (a belief in shared ability to implement health promotion). We expected commitment and efficacy to increase at intervention sites along with their self-reported effort to implement health promotion practices, termed wellness-program effort. We compared means between baseline and 15 months, and between intervention and control sites. We used linear regression to test whether intervention and control sites differed in their change-readiness scores over time.

Results

Only context and change commitment met reliability thresholds. Change commitment declined significantly for both control (-0.39) and interventions sites (-0.29) from baseline to 15 months, while context did not change for either. Only wellness program effort at 15 months, but not at baseline, differed significantly between control and intervention sites (1.20 controls, 2.02 intervention). Regression analyses resulted in two significant differences between intervention and control sites in changes from baseline to 15 months: (1) intervention sites exhibited significantly smaller change in context scores relative to control sites over time and (2) intervention sites exhibited significantly higher changes in wellness program effort relative to control sites.

Discussion

Contrary to our hypothesis, change commitment declined significantly at both Healthlinks and control sites, even as wellness-program effort increased significantly at HealthLinks sites. Regression to the mean may explain the decline in change commitment. Future research needs to assess whether baseline commitment is an independent predictor of wellness-program effort or an effect modifier of the HealthLinks intervention.

Comparing Strategies for Recruiting Small, Low-Wage Worksites for Community-Based Health Promotion Research

BACKGROUND

HealthLinks is a workplace health promotion program developed in partnership with the American Cancer Society. It delivers a package of evidence-based interventions and implementation support to small worksites in low-wage industries. As part of a randomized, controlled trial of HealthLinks, we studied approaches to recruiting these worksites.

AIMS

This study aims to guide future recruitment for community-based worksite health promotion interventions by comparing three approaches, including leveraging relationships with community partners.

METHOD

We recruited 78 small, low-wage worksites in King County, Washington, to participate in the trial via three approaches: phone calls to companies on a purchased list ("cold"), phone calls to a list of eligible companies provided by a health insurer ("lukewarm"), and personal referrals from local health insurers and brokers ("warm"). Eligible and interested worksites received an in-person visit from researchers and completed additional steps to enroll.

RESULTS

Of the worksites screened and deemed eligible, 32% of the "cold" worksites enrolled in HealthLinks, as did 48% and 60%, respectively, of the "lukewarm" and "warm" worksites. Compared with "warm" worksites, "cold" worksites were twice as likely to be ineligible.

DISCUSSION

Two distinct factors help explain why "warmer" worksites were more likely to enroll in HealthLinks. First, eligibility was significantly higher among warmer referrals. Second, most of the warm-referred worksites eligible for the study agreed to meet in person with the project team to hear more about the project.

CONCLUSIONS

"Warmer" recruitment approaches yielded higher recruitment. Leveraging relationships with community partners can help researchers identify and successfully recruit small, low-wage worksites.

The Role of Managers in Employee Wellness Programs: A Mixed-Methods Study

Purpose:

The purpose of this study is to evaluate managers’ barriers and facilitators to supporting employee participation in the Washington State Wellness program.

Design:

Exploratory sequential mixed methods.

Setting:

Four Washington State agencies located in Olympia and Tumwater, Washington.

Participants:

State employees in management positions (executive, middle, and line), whose job includes supervision of subordinates and responsibility for the performance and conduct of a subunit or group.

Methods:

We interviewed 23 managers and then used the results to create a survey that was fielded to all managers at the 4 agencies. The survey response rate was 65% (n = 607/935).

Analysis:

We used qualitative coding techniques to analyze interview transcripts and descriptive statistics to summarize survey data. We used the Total Worker Health framework to organize our findings and conclusions.

Results:

Managers support the wellness program, but they also face challenges with accommodating employees’ participation due to workload, scheduling inflexibility, and self-efficacy to discuss wellness with direct reports. About half the managers receive support from the manager above them, and most have not received training on the wellness program.

Conclusion:

Our findings point to several strategies that can strengthen managers’ role in supporting the wellness program: the provision of training, targeted messages, formal expectations, and encouragement (from the manager above) to support employees’ participation.

Managers’ Support for Employee Wellness Programs: An Integrative Review

Objective:

The aim of this integrative literature review is to synthesize the existing evidence regarding managers’ support for employee wellness programs.

Data Source:

The search utilized multiple electronic databases and libraries.

Study Inclusion and Exclusion Criteria:

Inclusion criteria comprised peer-reviewed research published in English, between 1990 and 2016, and examining managers’ support in the context of a worksite intervention. The final sample included 21 articles for analysis.

Data Extraction:

Two researchers extracted and described results from each of the included articles using a content analysis.

Data Synthesis:

Two researchers independently rated the quality of the included articles. Researchers synthesized data into a summary table by study design, sample, data collected, key findings, and quality rating.

Results:

Factors that may influence managers’ support include their organization’s management structure, senior leadership support, their expected roles, training on health topics, and their beliefs and attitudes toward wellness programs and employee health. Managers’ support may influence the organizational culture, employees’ perception of support, and employees’ behaviors.

Conclusions:

When designing interventions, health promotion practitioners and researchers should consider strategies that target senior, middle, and line managers’ support. Interventions need to include explicit measures of managers’ support as part of the evaluation plan.

Comprehensive Protocol to Sample and Process Bone Marrow for Measuring Measurable Residual Disease and Leukemic Stem Cells in Acute Myeloid Leukemia

Response criteria in acute myeloid leukemia (AML) has recently been re-established, with morphologic examination utilized to determine whether patients have achieved complete remission (CR). Approximately half of the adult patients who entered CR will relapse within 12 months due to the outgrowth of residual AML cells in the bone marrow. The quantitation of these remaining leukemia cells, known as minimal or measurable residual disease (MRD), can be a robust biomarker for the prediction of these relapses. Moreover, retrospective analysis of several studies has shown that the presence of MRD in the bone marrow of AML patients correlates with poor survival. Not only is the total leukemic population, reflected by cells harboring a leukemia associated immune-phenotype (LAIP), associated with clinical outcome, but so is the immature low frequency subpopulation of leukemia stem cells (LSC), both of which can be monitored through flow cytometry MRD or MRD-like approaches. The availability of sensitive assays that enable detection of residual leukemia (stem) cells on the basis of disease-specific or disease-associated features (abnormal molecular markers or aberrant immunophenotypes) have drastically improved MRD assessment in AML. However, given the inherent heterogeneity and complexity of AML as a disease, methods for sampling bone marrow and performing MRD and LSC analysis should be harmonized when possible. In this manuscript we describe a detailed methodology for adequate bone marrow aspirate sampling, transport, sample processing for optimal multi-color flow cytometry assessment, and gating strategies to assess MRD and LSC to aid in therapeutic decision making for AML patients.

A High-Definition Video Teaching Module for Thyroidectomy Surgery

OBJECTIVE

With the changing landscape of postgraduate surgical education to competency-based curricula, there emerges a need for alternative forms of training. Video teaching modules have been shown to be effective tools in surgical education, complementing traditional postgraduate curricula. There is a lack of validated modules described in the literature, specifically for teaching thyroidectomy. The primary objective of this study was to develop and validate a high definition video-based teaching module instructing thyroidectomy surgery to Otolaryngology-Head and Neck Surgery trainees.

DESIGN

This prospective study included intermediate to senior Otolaryngology-Head and Neck Surgery residents. Each participant first performed a thyroid lobectomy, serving as the initial assessment. After a washout period of at least 3 weeks, each participant was given the teaching module. The 15-minute module was developed using a 3-camera system and detailed a step-by-step approach to the surgery. After exposure to the module, each trainee performed the same procedure. Recordings of both procedures were deidentified and reviewed by a blinded, independent evaluator. Scoring was done using the Observational Clinical Human Reliability Assessment (OCHRA) system.

SETTING

University of Alberta Hospital and Royal Alexandra Hospital, Edmonton, Alberta, Canada.

PARTICIPANTS

A total of 6 intermediate to senior Otolaryngology-Head and Neck Surgery residents entered and completed the study.

RESULTS

The mean error rate was 8.8 errors per procedure before module exposure and 4.5 errors per procedure after exposure, representing a 49% decrease in error occurrence (p < 0.05). The mean staff takeover event rate was 10.5 takeovers per procedure prior to module exposure and 5.0 takeovers per procedure after exposure, representing a 52% decrease in error occurrence (p < 0.05).

CONCLUSION

High-definition video teaching modules are a useful complement to traditional surgical training. In a climate where new innovations for teaching thyroid surgery are needed, properly constructed and validated video teaching modules can serve as important tools in supplementing traditional surgical training.

Bridging the Gap After Physical Therapy: Clinical-Community Linkages With Older Adult Physical Activity Programs

BACKGROUND AND OBJECTIVES

Many barriers exist to older adult participation in physical activity, despite known benefits. Referrals from physical therapists (PTs) through clinical-community linkages offer novel, promising opportunities to increase older adult engagement in appropriate community-based physical activity programs. We assessed the capacity of PTs to participate in such linkages.

RESEARCH DESIGN AND METHODS

We collected qualitative data using semistructured phone interviews (n = 30) with PTs across 14 states. We conducted thematic analysis using a priori themes based on the 2008 Bridging Model of Etz and colleagues: capacity to assess patient risk, ability to provide brief counseling, capacity and ability to refer, and awareness of community resources.

RESULTS

Risk assessment and counseling were already part of routine practice for our respondents, but counseling could be further facilitated if PTs had more skills to engage less-motivated patients. PTs expressed a desire to refer their patients to community programs; however, barriers to referrals included lack of knowledge of and trust in community programs, and limited infrastructure for communicating with potential partners.

DISCUSSION AND IMPLICATIONS

PTs have the capacity to develop patient referral linkages with community-based physical activity programs. PT session length and content facilitates patient risk assessment and behavioral counseling. Integrating motivational techniques can help PTs engage less-motivated patients in physical activity. Systemic improvements should include innovations in communication infrastructure, identifying clinic-level champions, and in-person outreach initiated by organizations that deliver community physical activity programs.

Calcium/calmodulin-dependent kinase kinase 2 regulates hematopoietic stem and progenitor cell regeneration

Hematopoietic stem and progenitor cells (HSPCs) are predominantly quiescent in adults, but proliferate in response to bone marrow (BM) injury. Here, we show that deletion of Ca²⁺/calmodulin (CaM)-dependent protein kinase kinase 2 (CaMKK2) promotes HSPC regeneration and hematopoietic recovery following radiation injury. Using Camkk2-enhanced green fluorescent protein (EGFP) reporter mice, we found that Camkk2 expression is developmentally regulated in HSPC. Deletion of Camkk2 in HSPC results in a significant downregulation of genes affiliated with the quiescent signature. Accordingly, HSPC from Camkk2 null mice have a high proliferative capability when stimulated in vitro in the presence of BM-derived endothelial cells. In addition, Camkk2 null mice are more resistant to radiation injury and show accelerated hematopoietic recovery, enhanced HSPC regeneration and ultimately a prolonged survival following sublethal or lethal total body irradiation. Mechanistically, we propose that CaMKK2 regulates the HSPC response to hematopoietic damage by coupling radiation signaling to activation of the anti-proliferative AMP-activated protein kinase. Finally, we demonstrated that systemic administration of the small molecule CaMKK2 inhibitor, STO-609, to irradiated mice enhanced HSPC recovery and improved survival. These findings identify CaMKK2 as an important regulator of HSPC regeneration and demonstrate CaMKK2 inhibition is a novel approach to promoting hematopoietic recovery after BM injury.

Functional and quality of life outcomes after partial glossectomy: a multi-institutional longitudinal study of the head and neck research network

BACKGROUND

While aggressive treatment for oral cancer may optimize survival, decrements in speech and swallowing function and quality of life often result. This exploratory study investigated how patients recover their communicative function, swallowing ability, and quality of life after primary surgery [with or without adjuvant (chemo)radiation therapy] for tongue cancer over the course of the first year post-operation.

METHODS

Patients treated for oral cancer at three institutions (University of Alberta Hospital, Mount Sinai Beth Israel Medical Center, and Turku University Hospital) were administered patient-reported outcomes assessing speech [Speech Handicap Index (SHI)], swallowing [(M.D. Anderson Dysphagia Inventory (MDADI)] and quality of life [European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Head and Neck Module (EORTC-H&N35)]. Outcome measures were completed pre-operatively and at 1-, 6-, and 12-months post-operatively.

RESULTS

One hundred and seventeen patients undergoing partial glossectomy with reconstruction participated in this study. Results indicated no significant differences in swallowing function (MDADI and EORTC-H&N35 subscales) between baseline and 6 months post-surgery and no significant differences in speech function (SHI subscales) between baseline and 1 year post-surgery. Most quality of life domains (EORTC-H&N35 subscales) returned to baseline levels by 1 year post-operation, while difficulties with dry mouth and sticky saliva persisted. A clear time trend of adjuvant (chemo)radiation therapy negatively affecting dry mouth scores over time was identified in this study, while negative independent effects of chemoradiation on MDADI swallowing, and EORTC-H&N35 swallowing, eating, and opening mouth subscales were found.

CONCLUSIONS

Assessment time influenced patient-reported speech, swallowing, and quality of life outcomes, while treatment (by time) effects were found for only swallowing and quality of life outcomes. Results of the present study will help guide clinical care and will be useful for patient counseling on expected short and long-term functional and quality of life outcomes of surgical and adjuvant treatment for oral cavity cancer.
