Abstract
Sunscreens and photoprotection tools along with consumer habits and behaviors, can mitigate the skin damage caused by excessive solar radiation. For example, protecting oneself in the shade, avoiding inadequate sun exposure at times of higher incidence of UVB radiation (between 10:00 a.m. and 4:00 p.m.), wearing clothes with sun protection factors, applying sunscreens at the correct amounts and intervals, and wearing glasses with anti-UVA and UVB lenses are effective measures for protecting an individual. Therefore, the objective of this review was to highlight the importance of photoprotection for all skin phototypes, as skin cancer is a worldwide public health problem. In this review of the scientific literature on the Scopus platform between 2015 and 2022, we addressed the most common behaviors among different individuals and their phototypes, the importance of clarifying population habits against solar radiation, and the use of sunscreens and photoprotection tools to provide advice on healthy and safe sun exposure.

Abstract
Within solar ultraviolet (UV) light, the longest UVA1 wavelengths, with significant and relatively constant levels all year round and large penetration properties, produce effects in all cutaneous layers. Their effects, mediated by numerous endogenous chromophores, primarily involve the generation of reactive oxygen species (ROS). The resulting oxidative stress is the major mode of action of UVA1, responsible for lipid peroxidation, protein carbonylation, DNA lesions and subsequent intracellular signaling cascades. These molecular changes lead to mutations, apoptosis, dermis remodeling, inflammatory reactions and abnormal immune responses. The altered biological functions contribute to clinical consequences such as hyperpigmentation, inflammation, photoimmunosuppression, sun allergies, photoaging and photocancers. Such harmful impacts have also been reported after the use of UVA1 phototherapy or tanning beds. Furthermore, other external aggressors, such as pollutants and visible light (Vis), were shown to induce independent, cumulative and synergistic effects with UVA1 rays. In this review, we synthetize the biological and clinical effects of UVA1 and the complementary effects of UVA1 with pollutants or Vis. The identified deleterious biological impact of UVA1 contributing to clinical consequences, combined with the predominance of UVA1 rays in solar UV radiation, constitute a solid rational for the need for a broad photoprotection, including UVA1 up to 400 nm.

Abstract
BACKGROUND Cutaneous melanoma is strongly associated with tanning bed use. OBJECTIVE To describe local residents' knowledge, attitudes, and behavior regarding skin cancer and tanning bed use and to estimate prevalence of high risk for melanoma. MATERIALS AND METHODS A survey was mailed to 886 local residents (549, aged 18-39 years; 337, aged ≥40 years). Logistic and linear regression and univariate and multivariable analysis were used to assess perceived risk and skin cancer knowledge. RESULTS The response rate was 21%; 55% of the younger group and 37% of the older group had used indoor tanning, and prevalence of high risk for melanoma according to a skin cancer risk calculator was 18% in the younger group and 33% in the older group. Individuals with high risk scores were more likely to correctly perceive that they were at high risk for skin cancer. Most participants with high risk scores and those who previously used tanning beds reported low likelihood of future indoor tanning. CONCLUSION Female sex, high risk score, and previous indoor tanning were associated with participants' views of higher skin cancer risk. No specific knowledge gaps were identified. Understanding community residents' attitudes about skin cancer and indoor tanning can help guide interventions.

To ban or not to ban tanning bed use for minors: A cost-effectiveness analysis from multiple US perspectives for invasive melanoma. Cancer 2021; 127:2333-2341. [PMID: 33844296 DOI: 10.1002/cncr.33499] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 12/13/2020] [Accepted: 01/29/2021] [Indexed: 11/05/2022]
Abstract
BACKGROUND Tanning bed use is common among US adolescents, but is associated with increased melanoma risk. The decision to ban tanning bed use by adolescents should be made in consideration of the potential health benefits and costs. METHODS The US population aged 14 to 17 years was modeled by microsimulation, which compared ban versus no ban strategies. Lifetime quality-adjusted life years (QALYs) and costs were estimated from a health care sector perspective and two societal perspectives: with and without the costs of policy enforcement and the economic losses of the indoor-tanning bed industry. RESULTS Full adherence to the ban prevented 15,102 melanoma cases and 3299 recurrences among 17.1 million minors, saving $61in formal and informal health care costs per minor and providing an increase of 0.0002 QALYs. Despite the intervention costs of the ban and the economic losses to the indoor-tanning industry, banning was still the dominant strategy, with a savings of $12 per minor and $205.4 million among 17.1 million minors. Findings were robust against varying inspection costs and ban compliance, but were sensitive to lower excess risk of melanoma with early exposure to tanning beds. CONCLUSIONS A ban on tanning beds for minors potentially lowers costs and increases cost effectiveness. Even after accounting for the costs of implementing a ban, it may be considered cost effective. Even after accounting for the costs of implementing a ban and economic losses in the indoor-tanning industry, a tanning bed ban for US minors may be considered cost effective. A ban has the potential to reduce the number of melanoma cases while decreasing health care costs. LAY SUMMARY Previous meta-analyses have linked tanning bed use with an increased risk of melanoma, particularly with initial use at a young age. Yet, it remains unclear whether a ban of adolescents would be cost effective. Overall, a ban has the potential to reduce the number of melanoma cases while promoting a decrease in health care costs. Even after accounting for the costs of implementing a ban and the economic losses incurred by the indoor-tanning industry, a ban would be cost effective.

The Lipoxin Receptor/FPR2 Agonist BML-111 Protects Mouse Skin Against Ultraviolet B Radiation. Molecules 2020; 25:molecules25122953.

Abstract
Excessive exposure to UV, especially UVB, is the most important risk factor for skin cancer and premature skin aging. The identification of the specialized pro-resolving lipid mediators (SPMs) challenged the preexisting paradigm of how inflammation ends. Rather than a passive process, the resolution of inflammation relies on the active production of SPMs, such as Lipoxins (Lx), Maresins, protectins, and Resolvins. LXA4 is an SPM that exerts its action through ALX/FPR2 receptor. Stable ALX/FPR2 agonists are required because SPMs can be quickly metabolized within tissues near the site of formation. BML-111 is a commercially available synthetic ALX/FPR2 receptor agonist with analgesic, antioxidant, and anti-inflammatory properties. Based on that, we aimed to determine the effect of BML-111 in a model of UVB-induced skin inflammation in hairless mice. We demonstrated that BML-111 ameliorates the signs of UVB-induced skin inflammation by reducing neutrophil recruitment and mast cell activation. Reduction of these cells by BML-111 led to lower number of sunburn cells formation, decrease in epidermal thickness, collagen degradation, cytokine production (TNF-α, IL-1β, IL-6, TGF, and IL-10), and oxidative stress (observed by an increase in total antioxidant capacity and Nrf2 signaling pathway), indicating that BML-111 might be a promising drug to treat skin disorders.

Abstract
Evidence of the dangers of indoor tanning and its popularity, including among youth, led the Government of Ontario to pass the Skin Cancer Prevention Act (Tanning Beds) (SCPA) in 2014. This legislation includes prohibiting the sale of indoor tanning services to individuals under 18, requiring warning signs be posted, and other safety regulations. We collected information from Ontario Public Health Units to conduct a process evaluation of the SCPA to: understand legislation implementation; assess available evidence about compliance, inspection, and enforcement; and, note barriers and facilitators related to inspection and enforcement. Data was collected March-April 2018. All 36 Ontario Public Health Units were invited to participate in an online questionnaire about the SCPA. Questions covered complaints, inspection, and enforcement, and used both close- and open-ended questions. Participants from 20 Public Health Units responded to the questionnaire; a response rate of 56%. These agencies reported 485 facilities offer indoor tanning. Since 2014, there have been 242 infractions by tanning facility owner/operators related to the SCPA, with most being uncovered during non-mandatory routine inspections (n = 234, 97%), rather than mandatory complaint-based inspections (n = 8, 3%). Most infractions were related to warning signs (n = 201, 83%). No charges were issued for any infractions. Instead, providing education (n = 90, 62%) and issuing warnings (n = 33, 23%) were the most common enforcement strategies. SCPA amendments are needed, including mandatory, routinely scheduled inspections. In addition to providing education, fines may improve compliance. More resources are required for inspection and enforcement of the SCPA.

Abstract
Importance Melanoma is one of the most common cancers worldwide, typically diagnosed in older adults. There is an increasing incidence in the younger population (age ≤40 years) in America. In addition, approximately 1 in 5 cases of melanoma affect the head and neck. However, there are limited data on the incidence of head and neck melanoma in the pediatric, adolescent, and young adult population in North America (United States and Canada). Objective To assess 20-year demographic and incidence changes associated with head and neck melanoma in the pediatric, adolescent, and young adult population in North America. Design, Setting, and Participants A descriptive analysis of retrospective data on head and neck melanoma from the North American Association of Central Cancer Registries' Cancer in North America public use data set from 1995 to 2014 was conducted. The data set currently includes 93% of the United States and 64% of the Canadian populations. Eligible data were from 12 462 pediatric, adolescent, and young adult patients (aged 0-39 years) with a confirmed diagnosis of melanoma (International Classification of Diseases-Oncology 3 histologic types 8720-8790) in primary head and neck sites: skin of lip, not otherwise specified (C44.0); eyelid (C44.1); external ear (C44.2); skin of other/unspecified parts of face (C44.3); and skin of scalp and neck (C44.4). The study was conducted from January 26 to July 21, 2019. Main Outcomes and Measures Log-linear regression was used to estimate annual percentage change in age-adjusted incidence rates (AAIRs) of head and neck melanoma. Results Of the 12 462 patients with head and neck melanoma included in the study, 6810 were male (54.6%). The AAIR was 0.51 per 100 000 persons (95% CI, 0.50-0.52 per 100 000 persons). In North America, the incidence of head and neck melanoma increased by 51.1% from 1995 to 2014. The rate was higher in the United States (AAIR, 0.52; 95% CI, 0.51-0.53 per 100 000 person-years) than Canada (AAIR, 0.43; 95% CI, 0.40-0.45 per 100 000 persons). In the United States, the incidence increased 4.68% yearly from 1995 to 2000 and 1.15% yearly from 2000 to 2014. In Canada, the incidence increased 2.18% yearly from 1995 to 2014. Male sex (AAIR, 0.55; 95% CI, 0.54-0.57 per 100 000 persons), older age (AAIR, 0.79; 95% CI, 0.79-0.80 per 100 000 persons), and non-Hispanic white race/ethnicity (AAIR, 0.79; 95% CI, 0.77-0.80 per 100 000 persons) were associated with an increased incidence of head and neck melanoma. Conclusions and Relevance The incidence of pediatric, adolescent, and young adult head and neck melanoma in North America appears to have increased by 51.1% in the past 2 decades, with males aged 15 to 39 years the main cohort associated with the increase.

Abstract
UV-induced DNA damage plays a key role in the initiation phase of skin cancer. When left unrepaired or when damaged cells are not eliminated by apoptosis, DNA lesions express their mutagneic properties, leading to the activation of proto-oncogene or the inactivation of tumor suppression genes. The chemical nature and the amount of DNA damage strongly depend on the wavelength of the incident photons. The most energetic part of the solar spectrum at the Earth's surface (UVB, 280-320 nm) leads to the formation of cyclobutane pyrimidine dimers (CPDs) and pyrimidine (6-4) pyrimidone photoproducts (64PPs). Less energetic but 20-times more intense UVA (320-400 nm) also induces the formation of CPDs together with a wide variety of oxidatively generated lesions such as single strand breaks and oxidized bases. Among those, 8-oxo-7,8-dihydroguanine (8-oxoGua) is the most frequent since it can be produced by several mechanisms. Data available on the respective yield of DNA photoproducts in cells and skin show that exposure to sunlight mostly induces pyrimidine dimers, which explains the mutational signature found in skin tumors, with lower amounts of 8-oxoGua and strand breaks. The present review aims at describing the basic photochemistry of DNA and discussing the quantitative formation of the different UV-induced DNA lesions reported in the literature. Additional information on mutagenesis, repair and photoprotection is briefly provided.

Abstract
Men continue to develop nonmelanoma skin cancer (NMSC) at higher rates than women, but the epidemiologic pattern of NMSC development is evolving. We present a selective, narrative review of the literature showing that there is a trend toward a development of basal cell carcinomas in women at younger ages, and highlight potential causes of this trend. We review evidence that indoor tanning is associated with the development of NMSC and show that young women use indoor tanning more than any other age-sex group. We discuss societal factors that relate to the tanning behavior of young women. Finally, we argue that facial NMSCs may have more of a negative impact on quality of life in women than in men.

Proportion and number of cancer cases and deaths attributable to potentially modifiable risk factors in the United States. CA Cancer J Clin 2018; 68:31-54.

Abstract
Contemporary information on the fraction of cancers that potentially could be prevented is useful for priority setting in cancer prevention and control. Herein, the authors estimate the proportion and number of invasive cancer cases and deaths, overall (excluding nonmelanoma skin cancers) and for 26 cancer types, in adults aged 30 years and older in the United States in 2014, that were attributable to major, potentially modifiable exposures (cigarette smoking; secondhand smoke; excess body weight; alcohol intake; consumption of red and processed meat; low consumption of fruits/vegetables, dietary fiber, and dietary calcium; physical inactivity; ultraviolet radiation; and 6 cancer-associated infections). The numbers of cancer cases were obtained from the Centers for Disease Control and Prevention (CDC) and the National Cancer Institute; the numbers of deaths were obtained from the CDC; risk factor prevalence estimates were obtained from nationally representative surveys; and associated relative risks of cancer were obtained from published, large-scale pooled analyses or meta-analyses. In the United States in 2014, an estimated 42.0% of all incident cancers (659,640 of 1570,975 cancers, excluding nonmelanoma skin cancers) and 45.1% of cancer deaths (265,150 of 587,521 deaths) were attributable to evaluated risk factors. Cigarette smoking accounted for the highest proportion of cancer cases (19.0%; 298,970 cases) and deaths (28.8%; 169,180 deaths), followed by excess body weight (7.8% and 6.5%, respectively) and alcohol intake (5.6% and 4.0%, respectively). Lung cancer had the highest number of cancers (184,970 cases) and deaths (132,960 deaths) attributable to evaluated risk factors, followed by colorectal cancer (76,910 cases and 28,290 deaths). These results, however, may underestimate the overall proportion of cancers attributable to modifiable factors, because the impact of all established risk factors could not be quantified, and many likely modifiable risk factors are not yet firmly established as causal. Nevertheless, these findings underscore the vast potential for reducing cancer morbidity and mortality through broad and equitable implementation of known preventive measures.

Abstract
Despite well-established links between exposure to ultraviolet radiation (UVR) and skin cancer, UVR-based tanning behaviors persist among college students. Understanding tanning motivations, perceptions, barriers, and demographic characteristics of this population is critical to modifying these behaviors, but is limited by variability in study design, sample size, and outcomes measured in the current literature. To help clarify the tanning behaviors of this population and provide a concise reference for future studies, this review examines existing reports to determine the comparability of tanning behaviors across multiple U.S. college populations. A systematic review of the literature was performed in July 2016 to identify studies investigating tanning behaviors among U.S. college students. Twenty-three studies met inclusion criteria. High rates of indoor tanning (IT) and outdoor tanning (OT) were found among college students. Key motivators included appearance, emotion, health perceptions, and the influence of parents, peers, and the media. Misconceptions regarding skin protection, low rates of sun protective behaviors, and tanning dependence were barriers against safe UVR exposure. Understudied demographic factors may account for variance in observed tanning behaviors, emphasizing the need for standardization efforts to consistently identify trends associated with geographical region, age, year in college, and sex. The findings presented in this review reaffirm that college students are at high risk for tanning-associated skin cancer, emphasizing the critical need for effective, targeted interventions. Improved interventions will reduce the burden of skin cancer within this group, ultimately contributing to longer, healthier lives.

Abstract
Melanocytes, a neural crest cell derivative, produce pigment to protect keratinocytes from ultraviolet radiation (UVR). Although melanocytic lesions such as nevi and cutaneous malignant melanomas are known to be associated with sun exposure, the role of UVR in oncogenesis is complex and has yet to be clearly elucidated. UVR appears to have a direct mutational role in inducing or promoting melanoma formation as well as an indirect role through microenvironmental changes. Recent advances in the modeling of human melanoma in animals have built platforms upon which prospective studies can begin to investigate these questions. This review will focus exclusively on genetically engineered mouse models of UVR-induced melanoma. The role that UVR has in mouse models depends on multiple factors, including the waveband, timing, and dose of UVR, as well as the nature of the oncogenic agent(s) driving melanomagenesis in the model. Work in the field has examined the role of neonatal and adult UVR, interactions between UVR and common melanoma oncogenes, the role of sunscreen in preventing melanoma, and the effect of UVR on immune function within the skin. Here we describe relevant mouse models and discuss how these models can best be translated to the study of human skin and cutaneous melanoma.
