Exposure to ultraviolet radiation (UV-R), from both natural and artificial tanning, heightens the risk of skin cancer by inducing molecular changes in cells and tissues. Despite established transcriptional alterations at a molecular level due to UV-R exposure, uncertainties persist regarding UV radiation characterization and subsequent genomic changes. Our study aimed to mechanistically explore dose- and time-dependent gene expression changes, that may drive short-term (e.g., sunburn) and long-term actinic (e...

The contact state of a seamless internal threaded copper tube and an aluminium foil fin not only affects the heat transfer efficiency of a tube-fin heat exchanger but also seriously affects its service life. In this study, hydraulic expansion technology was used to connect the copper tube with an internal thread with a 7 mm diameter to the fin of the heat exchanger. The influence of the expansion pressure and pressure holding time on the contact state was analysed through experiments and finite element simulation, and the variation law of the two on the contact state was obtained...

Within the framework of the Latin America and Caribbean region (LAC) Code Against Cancer 1st edition, the current work presents recommendations to reduce exposure to environmental and occupational carcinogenic agents relevant for LAC. Using the methodology established by the International Agency for Research on Cancer (IARC) in the World Code Against Cancer Framework and experience from developing the European Code Against Cancer 4th edition, a working group of LAC cancer-prevention experts reviewed the list of Group I IARC carcinogenic agents, identified prevalent environmental and occupational exposures in the region, and proposed evidence-based cancer prevention recommendations suited to the epidemiological, socioeconomic, and cultural conditions of LAC countries...

Artificial ultraviolet radiation from tanning beds has been classified as carcinogenic by the International Agency for Research on Cancer in 2009. Several countries have subsequently introduced comprehensive legislation regulating commercial indoor tanning. Specific aspects of these regulations address tanning bed advertising and information requirements for tanning bed customers, which have been previously neglected in international comparisons of indoor tanning regulations. We performed a systematic search regarding legislation on these aspects in 131 legislative units across three continents (North America, Australia/New Zealand, Europe)...

The use of tanning devices in Spain is regulated by the Royal Decree 1002/2002, which is based on the European standard EN60335-2-27. The European standard establishes that the total unweighted irradiance between 200 and 280 nm must not exceed 0.003 Wm-2 , a requirement that the Spanish regulation modified to 0.03 Wm-2 from 250 to 295 nm. With these differences, the compliance consideration of an artificial tanning device can vary. Spectral irradiance measurements of 41 tanning devices performed with a high-resolution spectroradiometer were analyzed...

BACKGROUND: Genetic factors have been found to be associated with the efficacy and adverse reactions of antiseizure medications. BCL11A is an important regulator of the development of neuronal networks. However, the role of BCL11A in epilepsy remains unclear. This study aimed to evaluate the genetic association of BCL11A with the susceptibility to develop epileptic seizures and therapeutic response of patients with epilepsy in Han Chinese. METHODS: We matched 450 epilepsy cases with 550 healthy controls and 131 drug-resistant epilepsy patients with 319 drug-responsive epilepsy patients from two different centers...

Indoor tanning (sunbeds, solarium) uses artificial ultraviolet radiation (UVR) to stimulate cosmetic tanning of the skin. Indoor tanning has been officially classified as a human carcinogen in 2009 by the International Agency for Research on Cancer of the World Health Organization (WHO). The differences in the prevalence of sunbed use across countries and over the years highlight underlying legislative, climatic, and cultural differences. Indoor tanning-seeking behaviors may be driven by motivations for an appealing appearance, largely influenced by gender and age, and several misconceptions that a prevacation tan safeguards the skin, that sunbeds can be used to treat acne or to increase vitamin D, or that tanning is a healthy habit...

Outdoor and indoor tanning are considered as risk factors for the development of skin cancer. The aims of this nationwide representative study were to quantify both behaviors in a sample with a wide age range, to identify those showing both behaviors and to explore and compare determinants of both behaviors. We used data from the fifth wave (2019) of the National Cancer Aid Monitoring (NCAM). We surveyed the representative sample including 4000 individuals, aged 16-65 years, living in Germany. Data were collected through telephone interviews...

Cutaneous melanoma incidence in European-origin populations has risen steeply, however, mortality has not, as 73 years of Danish cancer data strikingly show. It has been suggested that such divergent trends in the US are due to overdiagnosis from increasing diagnostic scrutiny and lowering diagnostic threshold. Alternatively, the increase in melanoma incidence may be largely due to increased sun exposure, which would imply that most of these new, sun-caused, melanomas are non-lethal. Consistent with this hypothesis, Icelandic data show an increase in melanoma incidence, predominantly in young women (<50 years), which paralleled increasing sunbed use that remitted after a campaign against sunbeds...

Drawing on the changing representations of sunbed consumers within everyday entertainment media and national newspapers from the late 1980s to early 1990s, this article will demonstrate how sunbed use was framed, at first, as an 'immoral' working-class activity, and later as a growing addictive threat to white adolescent women. Medical experts had finally confirmed that sunbeds increased the risk of developing skin cancer, and the media had taken this 'public health' matter into their own hands. As this occurred during a backlash against Thatcherism, their anti-sunbed coverage became entangled with moralised concerns about class, women and consumerism...

PURPOSE: Despite the established causal links to skin cancer, skin ageing and eye inflammation, people continue to use indoor tanning devices (hereafter 'sunbeds'). Understanding the reasons underlying the use of sunbeds is essential for developing effective interventions. The purpose of this study was to collate all existing evidence from qualitative papers published to date that had assessed motivations for using sunbeds. METHODS: Six databases were searched from inception to February 2020 for qualitative studies that explored adults' experiences of using sunbeds...

Tanning beds have been classified as carcinogenic to humans. As a result, many countries have enacted laws regulating the use of commercial tanning beds, including bans for minors. However, there is no international overview of the current legal status of access restrictions for minors that provides details on their specific design regarding age limits and possible exceptions to the statutory regulation. Therefore, we performed a comprehensive web search of current tanning bed legislation for minors on the three continents North America, Australia, and Europe...

Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis, are chronic, relapsing intestinal inflammatory disorders. Although the molecular mechanisms governing the pathogenesis of IBD are not completely clear, the main factors are presumed to be a complex interaction between genetic predisposition, host immune response and environmental exposure, especially the intestinal microbiome. Currently, most studies have focused on the role of gut bacteria in the onset and development of IBD, whereas little attention has been paid to the enteroviruses...

The aim of this study was to examine the association between indoor tanning use and the risk of overall and early-onset (age < 50) melanoma and non-melanoma skin cancer (NMSC). To evaluate the association between indoor tanning and skin cancer, a systematic review of the literature published until July 2021 was performed using PubMed, EMBASE, and MEDLINE. Summary relative risk (RR) from 18 studies with 10,406 NMSC cases and 36 studies with 14,583 melanoma cases showed significant association between skin cancer and indoor tanning (melanoma, RR= 1...

Indoor tanning is associated with an increased risk of skin cancer. Nonetheless, its use is still widespread. We aimed to investigate the socio-demographic and clinical characteristics of sunbed users in a group of participants in the skin cancer prevention campaign organized by the Italian Cancer League (LILT). During almost 2 years, 4409 individuals were screened in 18 centers. Participants reported having used sunbeds before the age of 15 years in 2.2% of cases, while after age 15 the prevalence of use was 22...

BACKGROUND: Melanotan II (MT II) is a synthetic analogue of α-melanocyte-stimulating hormone that, via interaction with the melanocortin 1 receptor, induces skin hyperpigmentation. The unregulated acquisition of MT II injections via the internet and other outlets has become popular over the last decades in order to exploit its properties for use as a tanning agent. Due to the covert nature of MT II use, it is difficult to assess the extent of its use among the general population and to characterise any associated side effects...

Patients with acne are increasingly using sunbeds as a self-treatment despite harmful effects. Little is known about sunbed use in adult acne patients under dermatology care. This questionnaire study explored prevalence and behaviours surrounding sunbed use in acne patients at a UK dermatology centre. 26% of respondents used sunbeds and were more likely to be older, female, have a longer duration of acne diagnosis and have previously been offered blue light therapy by their doctor (p<0.05 for all). 72% tanned at least weekly...
