Sebaceous carcinoma epidemiology, associated malignancies and Lynch/Muir-Torre syndrome screening in England from 2008 to 2018

BACKGROUND

Sebaceous carcinomas (SC) may be associated with the cancer predisposition syndrome Muir-Torre/Lynch syndrome (MTS/LS), identifiable by SC mismatch repair (MMR) screening; however, there is limited data on MMR status of SC.

OBJECTIVE

To describe the epidemiology of SC, copresentation of other cancers, and population level frequency of MMR screening in SC.

METHODS

A population-based retrospective cohort study of SC patients in the National Cancer Registration and Analysis Service in England.

RESULTS

This study included 1077 SC cases (739 extraocular, 338 periocular). Age-standardized incidence rates (ASIR) were higher in men compared with women, 2.74 (95% CI, 2.52-9.69) per 1,000,000 person-years for men versus 1.47 person-years (95% CI, 1.4-1.62) for women. Of the patients, 19% (210/1077) developed at least one MTS/LS-associated malignancy. MMR immunohistochemical screening was performed in only 20% (220/1077) of SC tumors; of these, 32% (70/219) of tumors were MMR deficient.

LIMITATIONS

Retrospective design.

CONCLUSIONS

Incorporation of MMR screening into clinical practice guidelines for the management of SC will increase the opportunity for MTS/LS diagnoses, with implications for cancer surveillance, chemoprevention with aspirin, and immunotherapy treatment targeted to MTS/LS cancers.

A Social Media-Based Public Health Campaign to Reduce Indoor Tanning in High-Risk Populations

Introduction

Indoor tanning beds cause more than 450,000 new skin cancers each year, yet their use remains common, with a global indoor tanning prevalence of 10.4%. Social media provides an opportunity for cost-effective, targeted public health messaging. We sought to direct Instagram users at high risk of indoor tanning to accurate health information about the risks of indoor tanning and to reduce indoor tanning bed use.

Methods

We disseminated a public health campaign on Instagram on April 6-27, 2022 with 34 video and still-image advertisements. We had 2 target audiences at high risk of indoor tanning: women aged 18-30 years in Kentucky, Nebraska, Ohio, or Tennessee interested in indoor tanning and men aged 18-45 years in California interested in indoor tanning. To evaluate the impact of the campaign, we tracked online metrics, including website visits, and conducted an interrupted time-series analysis of foot traffic data in our target states for all tanning salons documented on SafeGraph from January 1, 2018 to 3 months after the campaign.

Results

Our indoor tanning health information advertisements appeared on Instagram feeds 9.1 million times, reaching 1.06 million individuals. We received 7,004 views of our indoor tanning health information landing page (Average Time on Page of 56 seconds). We did not identify a significant impact on foot traffic data on tanning salons.

Conclusions

We show the successful use of social media advertising to direct high-risk groups to online health information about indoor tanning. Future research quantifying tanning visits before and after indoor tanning interventions is needed to guide future public health efforts.

Patient Perspectives of Health System Barriers to Accessing Care for Hidradenitis Suppurativa: A Qualitative Study

Importance

Patient-perceived barriers to hidradenitis suppurativa (HS) care are poorly understood. Understanding health care barriers is a critical first step toward improving care for this population.

Objective

To characterize the health care experiences of people living with HS, including perceived barriers and facilitators to health care access, and to elucidate potential associations among these barriers and facilitators, health care access, and disease activity.

Design, Setting, and Participants

In this qualitative study, an inductive thematic analysis was conducted on 45 in-depth, 60- to 90-minute semistructured interviews of 45 people with HS from diverse sociodemographic backgrounds that took place between March and April 2020. Individuals were eligible if they could speak English, were 18 years or older, and were diagnosed with HS. A diagnosis of HS was confirmed through physician diagnosis or through self-reported, affirmative response to the validated screening question, "Do you experience boils in your armpits or groin that recur at least every six months?"

Main Outcomes and Measures

Interviews were audio recorded and transcribed verbatim. A modified grounded theory approach was used to develop the codebook, which investigators used for inductive thematic analysis.

Results

Among the 45 participants included, the median (IQR) age was 37 (16) years, 33 (73%) were female, and 22 (49%) were White. There were 6 interrelated themes associated with participant-perceived barriers to accessing HS care: (1) bidirectional associations of disease activity and employment, (2) association of employment with health care coverage, (3) association of health care coverage with costs and perceived access to care, (4) association of costs with access to patient-centered care, (5) health care professional attitudes and knowledge influence patient-centered care and perceived access to care and disease activity, and (6) health system characteristics influence patient-centered care and associated costs, perceived access to care, and disease activity.

Conclusions and Relevance

This qualitative study highlights themes that generate a conceptual model for understanding barriers that may act synergistically to limit health care access and influence disease activity. The disease activity of HS may be reduced when cycle elements are optimized. This study also highlights areas for future investigations and potential systems-level changes to improve access to patient-centered HS care.

The perspectives of 606 US dermatologists on active surveillance for low-risk basal cell carcinoma

In this survey study of over 600 US dermatologists, identical clinical scenarios (10mm primary asymptomatic BCC) were presented except for randomly varied patient characteristics including age, life expectancy, and tumor location. Most dermatologists (62%) recommended active surveillance for patients with advanced age (91 years) and a 1-year life expectancy. The odds ratio for choosing active surveillance was 20.31 (95% CI 14.10-35.30) comparing a patient with a 1-year life expectancy to a healthy patient.

Qualitative exploration of melanoma awareness in black people in the USA

OBJECTIVE

Although black patients are more likely to have advanced melanomas at diagnosis, with a 5-year survival rate among black patients of 70% compared with 92% for white patients, black people are generally not the focus of melanoma public health campaigns. We sought to explore awareness and perspectives of melanoma among black people to inform the development of relevant and valued public health messages to promote early detection of melanoma.

DESIGN

Inductive thematic analysis of in-depth semistructured interviews.

SETTING

Interviews were conducted with participants via video software or telephone in the USA.

PARTICIPANTS

Participants were adults from the USA who self-identified as African American or black. Recruitment flyers were posted around the San Francisco Bay Area and shared on our team Facebook page, with further participants identified through snowball sampling.

RESULTS

We interviewed 26 participants from 10 different states. Overall, 12 were men and 14 were women, with a mean age of 43 years (range 18-85). We identified five key themes regarding melanoma awareness in black people: (1) lack of understanding of term 'melanoma' and features of skin cancer; (2) do not feel at risk of melanoma skin cancer; (3) surprise that melanoma can occur on palms, soles and nails; (4) skin cancer awareness messages do not apply to or include black people; and (5) Importance of relationship with healthcare and habits of utilisation.

CONCLUSIONS

Analysis of these in-depth semistructured interviews illuminate the pressing need for health information on melanoma designed specifically for black people. We highlight two key points for focused public health messaging: (1) melanoma skin cancer does occur in black people and (2) high-risk sites for melanoma in black people include the palms, soles and nail beds. Therefore, public health messages for black people and their healthcare providers may involve productively checking these body surface areas.

Social Media for Public Health: Framework for Social Media-Based Public Health Campaigns

The pervasiveness of social media is irrefutable, with 72% of adults reporting using at least one social media platform and an average daily usage of 2 hours. Social media has been shown to influence health-related behaviors, and it offers a powerful tool through which we can rapidly reach large segments of the population with tailored health messaging. However, despite increasing interest in using social media for dissemination of public health messaging and research exploring the dangers of misinformation on social media, the specifics of how public health practitioners can effectively use social media for health promotion are not well described. In this viewpoint, we propose a novel framework with the following 5 key principles to guide the use of social media for public health campaigns: (1) tailoring messages and targeting them to specific populations-this may include targeting messages to specific populations based on age, sex, or language spoken; interests; or geotargeting messages at state, city, or zip code level; (2) including members of the target population in message development-messages should be designed with and approved by members of the community they are designed to reach, to ensure cultural sensitivity and trust-building; (3) identifying and addressing misinformation-public health practitioners can directly address misinformation through myth-busting messages, in which false claims are highlighted and explained and accurate information reiterated; (4) leveraging information sharing-when designing messages for social media, it is crucial to consider their "shareability," and consider partnering with social media influencers who are trusted messengers among their online followers; and (5) evaluating impact by measuring real-world outcomes, for example measuring foot traffic data. Leveraging social media to deliver public health campaigns enables us to capitalize on sophisticated for-profit advertising techniques to disseminate tailored messaging directly to communities that need it most, with a precision far beyond the reaches of conventional mass media. We call for the Centers for Disease Control and Prevention as well as state and local public health agencies to continue to optimize and rigorously evaluate the use of social media for health promotion.

A Social Media‒Based Public Health Campaign Encouraging COVID-19 Vaccination Across the United States

Tailored public health messaging encouraging COVID-19 vaccination may help increase vaccination rates and decrease the burden of COVID-19. We conducted a three-part COVID-19 vaccine uptake public health campaign disseminated on Facebook between April and June 2021. Our first campaign focused on reaching Black and Latinx communities; our second campaign focused on addressing vaccine access and scheduling in Latinx communities; and our third campaign focused on religious communities. Overall, we reached 25 million individuals with 171 million views across the United States. (Am J Public Health. 2022;112(9):1253-1256. https://doi.org/10.2105/AJPH.2022.306934).

"Is this the GVHD?" A qualitative exploration of quality of life issues in individuals with graft-versus-host disease following allogeneic stem cell transplant and their experiences of a specialist multidisciplinary bone marrow transplant service

BACKGROUND

Graft-versus-host disease (GVHD) is a significant cause of morbidity and mortality following allogeneic stem cell transplantation. These patients face unique challenges due to the complexity of GVHD which can affect multiple organ systems, and the toxicity of treatments. Despite the known impact on quality of life (QOL), qualitative data within the bone marrow transplantation (BMT) literature is rare, and there has been no qualitative work exploring patient experience of specialist healthcare provision for GVHD in the United Kingdom.

METHODS

We conducted a primary explorative qualitative study of the experience of QOL issues and multidisciplinary care in patients with chronic GVHD following allogeneic stem cell transplantation. Eight patients were identified using convenience sampling from specialist BMT outpatient clinics. Following consent, patients were interviewed individually via telephone. Transcripts of interviews were analyzed using an inductive thematic approach.

RESULTS

Mean participant age was 61-years-old (range 45-68), with a mean time post-transplant of 3 years at time of interview (range 3 months-15 years). Five key QOL themes were identified: (1) 'Restricted as to what I can do'; (2) Troubling symptoms-'you can sort of get GVHD anywhere'; (3) Confusion/uncertainty over GVHD symptoms-'Is this the GVHD?'; (4) Unpredictable course and uncertainty about the future; and (5) Adapting to the sick role. In addition, four themes related to experience of service provision were identified: (1) personal care and close relationship with BMT nurses; (2) efficiency versus long waits-'On the case straight away'; (3) information provision-'went into it with a bit of a rosy view'; and (4) the role of support groups.

CONCLUSIONS

These qualitative data reflect the heterogeneity of experiences of the GVHD patient population, reflecting the need for a flexible and nuanced approach to patient care with emphasis on comprehensive information provision. We have identified the key role that BMT specialist nurses within the multidisciplinary team play in supporting patients. We advocate future research should focus on ways to meet the complex needs of this patient group and ensure that the personal care and close relationships are not lost in service redesigns embracing remote consultations.
