Cancer league actions against sunbed use for skin cancer prevention

The incidence of non‐melanoma and melanoma skin cancer has been rising in Europe. Although the World Health Organization's International Agency for Research on Cancer has since 2009 classified sunbeds as a Group 1 carcinogen, sunbed use, especially by those under the age of 18, continues to be a concern. As the only platform for cancer leagues in Europe, the Association of European Cancer Leagues decided to explore interest and actions by its member leagues at the national level against sunbed use, to share experiences and to provide background information on possible future collective actions at the EU level.     

E‐cadherin and p120ctn protein expression are lost in hidradenitis suppurativa lesions

Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disease affecting the pilosebaceous units in the axilla, groin and buttocks. While the pathogenesis of HS is not clear, mechanical stress exacerbates HS. In this study, we aimed to determine whether intracellular adhesive junctions may be aberrant in HS patient skin. Strikingly, we observed loss of E‐cadherin and p120ctn protein expression, two key adherens junction proteins, in ~85% of HS severe skin lesions. Moreover, loss of protein expression was apparent in non‐lesional skin from HS patients and the degree of loss positively correlated with HS Hurley Stage of disease. E‐cadherin expression was unaltered in other inflammatory skin conditions including chronic wound epithelium, atopic dermatitis, and acne vulgaris compared with healthy skin suggesting that its loss may be uniquely relevant to HS pathogenesis. A complete loss of α‐catenin, β‐catenin and ZO‐1 was not observed; however, some cytoplasmic staining of the catenins was noted in HS epithelium. We also demonstrated diminished desmosome size in HS lesional skin. Overall, our data suggested that loss of adherens junction proteins and diminished desmosome size in HS skin contributes to the skin's inability to withstand mechanical stress and provides rationale as to why mechanical stress exacerbates HS symptoms.

A retrospective cohort study comparing non-fatal self-harm emergency department visits between Canadian veterans living in Ontario and matched civilians

Abstract

This was a retrospective cohort study linking provincial administrative databases to compare rates of non-fatal self-harm between CAF and RCMP veterans living in Ontario and age-matched civilians. This study included male veterans who registered for provincial health insurance between 2002 and 2013. A civilian comparator group was matched 4:1 on age and sex. Self-harm emergency department (ED) visits were identified from provincial ED admission records until death or December 31, 2015. Multivariable Poisson regression compared the risk of self-harm. Analyses adjusted for age, geography, income, rurality, and major physical and mental comorbidities. In total, 9514 male veterans and 38,042 age- and sex-matched civilians were included. Overall, 0.55% of veterans had at least one non-fatal self-harm ED visit, compared with 0.81% of civilians. The rate of ED self-harm visits was 40% lower in the veteran population, compared to the civilian population (RR?=?0.60; 95% CI?=?0.41–0.87). In both groups, psychosocial and physical comorbidities, and death by suicide were more common in those who self-harmed than those who did not. A better understanding of why veterans have a lower rate of self-harm emergency department visits and how it is related to the number of completed suicides is an important area for future consideration.
