Abstract
Hypovitaminosis D has been recognized as a worldwide pandemic, but there are disagreements regarding its diagnosis and treatment. This study aimed to evaluate the knowledge and practice of European pediatricians concerning vitamin D (VD) and hypovitaminosis D and their adherence to relevant guidelines. A cross-sectional study was conducted through an anonymous survey via SurveyMonkey on 304 European pediatricians. Most of the participants were general pediatricians, followed by endocrinologists and neonatologists. ESPGHAN's and the national guidelines were the most frequently used. VD testing was mostly performed in patients with skeletal, chronic kidney, and autoimmune diseases. Participants predominantly answered the questions regarding the definition of hypovitaminosis D and VD supplementation correctly, especially in children younger than 12 months. They showed the least knowledge regarding the cut off-point for the initiation of the therapy and therapeutic doses used to treat confirmed hypovitaminosis D. Participants' conflicting answers could be related to the differences between the guidelines. We consider that experts in this field should create uniform guidelines, and that those guidelines should also be promoted by national or local pediatric associations.

Lipid Nanomaterials for Targeted Delivery of Dermocosmetic Ingredients: Advances in Photoprotection and Skin Anti-Aging. NANOMATERIALS 2022; 12:nano12030377.

Abstract
Despite the health benefits of the sun, overexposure to solar radiation without proper precautions can cause irreversible damage to exposed skin. In the search for balance between the risks and benefits of exposure to solar radiation in human health, a technological alternative was found, the incorporation of photoprotective products in lipid nanoparticulate systems for topical application. These nanometric systems have demonstrated several advantages when used as adjuvants in photoprotection compared to chemical and/or physical sunscreens alone. The increase in the sun protection factor (SPF), photostability and UV action spectrum are parameters that have benefited from the application of these systems in order to increase the effectiveness and safety of photoprotective formulations containing organic and/or inorganic sunscreens.

An internet based approach to improve general practitioners' knowledge and practices: the development and pilot testing of the "ABC's of vitamin D" program. Int J Med Inform 2015; 84:413-22. [PMID: 25795505 DOI: 10.1016/j.ijmedinf.2015.01.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2014] [Revised: 01/11/2015] [Accepted: 01/12/2015] [Indexed: 11/23/2022]
Abstract
BACKGROUND Online continuing medical education (CME) offers a number of advantages for physicians including flexibility with regards to location and timing of use. In order to effect physician practices and improve patient outcomes, it is important that the development of online CME is theory and evidence-based. OBJECTIVES This paper aims to describe the development of an online CME program for practising general practitioners (GPs) on vitamin D and sun health called "The ABC's of Vitamin D for GPs" using elements of design principles for physician-education web sites as a framework. The paper will also report the program's usability and acceptability pilot test results. METHODS The ABC's of Vitamin D program was developed following nine principles: needs assessment; evidence-based content development; multimodal program and modularisation; clinical cases; tailoring and interactivity; audit and feedback; credibility of the web site host; patient education materials; ease of use and navigation. Among the 20 GPs invited, acceptability and useability was tested with 12 GPs (60%) who agreed to participate and were interviewed following use of the program. The study was conducted between 2011 and 2013. RESULTS An online CME program consisting of eight modules was constructed. Of the 12 participating GPs, most (n=11) reported that the program was clear and easy to understand, logical, easy to navigate, and took a reasonable amount of time (estimated between 1 and 3h) to complete. Eleven of 12 participants said they would use the program as an accredited CME activity and all participants indicated that the program was 'very or somewhat' likely to lead to changes in the advice patients are given. CONCLUSION This study found that a theory and evidence based approach for the development of an online CME program for GPs was acceptable to users. Further research is needed to examine whether the online CME program is effective at changing GP practices and improving patient outcomes.

Abstract
This study aimed to assess the attitudes, practices and knowledge of general practitioners (GPs) with regards to vitamin D. A cross-sectional survey of a random sample of GPs stratified by location of practice (rural/remote or metropolitan) and employment status (full-time or part-time) in New South Wales (NSW), Australia was conducted. Of 500 respondents, 58.1% (95% CI 53.8-62.4) reported that up to 39% of their tested patients showed vitamin D deficiency or insufficiency and a further 37.7% (95% CI 33.5-41.9) of respondents said that over 40% of their patients were vitamin D insufficient. Vitamin D supplementation and advice to receive more natural sunlight were the most common ways vitamin D insufficiency was managed (97.1%; 95% CI 95.6-98.6 and 82%, 95% CI 78.6-85.4, respectively). Some gaps in knowledge were identified. Most respondents (64%; 95% CI 59.8-68.2) believed that a person of average sun sensitivity required 10 min of direct sun exposure during summer in peak UV time and a further 21.6% (95% CI 18.0-25.2) believed that people required 30 min of direct sun. A third of respondents (33.1%; 95% CI 29.0-37.2) advised their patients to use sun protection at all times during winter. In general, the attitude items showed that respondents expressed greater concern about vitamin D deficiency than skin cancer. The results reveal some confusion in general practice regarding vitamin D, sun exposure, sun protection and skin cancer risk. Some of the advice that GPs are offering may needlessly increase their patients' risk for vitamin D insufficiency or skin cancer.

Abstract
Mismatches between skin pigmentation and modern lifestyle continue to challenge our naked skin. One of our responses to these challenges is the development and use of sunscreens. The management of sunscreens has to balance their protective effect against erythema, photocarcinogenesis and photoageing owing to the potential toxicity of the ultraviolet (UV) filters for humans and the environment. The protection against UV radiation offered by sunscreens was recently standardized in the European Union (EU) based on international harmonization of measurement techniques. Four different categories of sun protection have been implemented along with recommendations on how to use sunscreen products in order to obtain the labelled protection. The UV filters in sunscreens have long been authorized for use by the EU authority on the basis of data from studies on acute toxicity, subchronic and chronic toxicity, reproductive toxicity, genotoxicity, photogenotoxicity, carcinogenicity, irritation, sensitization, phototoxicity and photosensitization as well as on environmental aspects. New challenges with respect to the safety of UV filters have arisen from the banning of animal experiments for the development of cosmetics. Future debates on sunscreens are likely to focus on nanoparticles and environmental issues, along with motivation campaigns to persuade consumers to protect their skin. However, more efficient sunscreen use will also continue to raise questions on the benefit in preventing vitamin D synthesis in the skin induced by sunlight.

Abstract
Solar ultraviolet radiation (UVR) is a human carcinogen. The UK and the worldwide incidence of cutaneous (skin) melanoma are rising. It is now the second most common cancer in 15-34 year-olds in the UK, increasing by 49% in 1991—2000. The UK government prioritized skin cancer in 1992 in their public health strategy The Health of the Nation, and set the target for reducing the yearly rise in skin cancer incidence by 2005. In 1998 in the Saving Lives: Our Healthier Nation strategy, targets were set to reduce the death rate from cancer, including skin cancer, by 20% by 2010. As a consequence of these targets, since the mid-1990s public health campaigns to reduce sun exposure and skin cancer incidence in the UK have used specific interventions for at-risk groups and the mass media to reach the general population. Evidence indicates a shift in knowledge, with further work required to increase change in behaviour and attitudes. An associate health problem is vitamin D deficiency, which is prevalent across certain UK population groups. The main childhood health problem associated with vitamin D deficiency is the development of rickets, with evidence indicating those at high risk are exclusively breastfed dark-skinned infants, the elderly, those with dark skin pigmentation, and certain cultural groups that cover their bodies in clothing. Adolescents are the group with the highest incidence of low vitamin D status in the UK, with children of Asian descent at higher risk than Caucasian children. Increasing the outdoor activity levels of children in winter and during the cooler hours in summer is one way of increasing safe sun exposure. It is imperative to educate the general public on the risk of vitamin D deficiency, and offer advice on safe sun exposure, dietary sources of vitamin D, and dietary supplements. More research is required on recommendations for daily vitamin D supplements to determine optimal vitamin D levels in different population groups. There also needs to be reliable and accessible evidence on the links between vitamin D deficiency and lack of sun exposure, with sun safe messages adjusted accordingly.

Abstract
Solar radiation is the main cause of skin cancers. However, it also is a main source of vitamin D for humans. Because the optimal status of vitamin D protects against internal cancers and a number of other diseases, a controversy exists: Will increased sun exposure lead to net health benefits or risks? We calculated the relative yield of vitamin D photosynthesis as a function of latitude with a radiative transfer model and cylinder geometry for the human skin surface. The annual yield of vitamin D is 3.4 and 4.8 times larger below the equator than in the U.K. and Scandinavia, respectively. In populations with similar skin types, there are clear latitude gradients of all major forms of skin cancer, indicating a north-south gradient in real sun exposure. Surprisingly, the incidence rates of major internal cancers also increase from north to south. However, the survival prognosis also improves significantly from north to south. Reasons for these findings are discussed in view of the role of vitamin D. In Norway, melanoma rates increased by a factor of 6 from 1960 to 1990, while the prognosis improved in the same period. After 1990, melanoma rates have remained constant or even decreased in age groups <50 years, whereas the prognosis has not improved further. These data, together with those for internal cancers and the beneficial effects of an optimal vitamin D status, indicate that increased sun exposure may lead to improved cancer prognosis and, possibly, give more positive than adverse health effects.

Abstract
OBJECTIVE This study used latent class analysis (LCA) to identify homogeneous subgroups of individuals at risk for skin cancer on the basis of their risk factors and sun protection habits to understand patterns of sun exposure and sun protection behaviors. METHOD Adults (n = 725), screened to be at risk for skin cancer, were recruited through primary care physicians and completed the mailed baseline survey as part of a skin cancer prevention trial. LCA was used to identify homogeneous subgroups, on the basis of skin cancer risk and usual sun habits, by sex. LCA solutions were then validated by assessing if class predicted differences in sun exposure, recent sunburn, outdoor activities, attitudes toward tanning, and demographics. RESULTS Females and males were divided into four and three classes, respectively, that reflected the level of sun protection habits and showed that these habits were greater for those with higher constitutional risk for skin cancer. The classes seemed to represent a continuum of sun protection efforts rather than distinct patterns of protection behaviors. Females were distinguished on their use of all habits assessed whereas males, who reported less use of sun protection overall, only differed in their use of sunscreen. Females using more protection reported less sunburn whereas males using less protection reported less sunburn. However, all subgroups reported significant annual prevalence of sunburn (including mild) of 48% to 83%. CONCLUSION LCA can distinguish subgroups of at-risk adults that are relevant and valid. This technique is recommended for targeting intervention efforts when individual tailoring is not feasible.
