The Effect of Administration of Rosella Flower (Hibiscus Sabdariffa) Extract Gel on The Expression Of TNF-α And Caspase-3 Expression in An In Vivo Study of Wistar Strain Rats Exposed to Ultraviolet B-Lights

UV rays are oxidative because they can produce Reactive Oxygen Species and free radical compounds. The dangers of sun exposure can cause skin disorders such as aging at an early age (photoaging). Rosella flower petals can be used in medicine, jams, and natural food coloring because they contain flavonoids as antioxidants or free radical scavengers. The research aimed to determine the effect of administering Rosella (Hibiscus sabdariffa L.) flower extract gel on TNF-α expression and Caspase-3 expression in an in vivo study of Wistar mice exposed to UVB. This research is an experimental study. The sample for each treatment group consisted of 6 individuals, so the total research sample was 24. Data analysis used descriptive, normality, and homogeneity tests with data analysis processing using SPSS 25.0 for Windows. The study found that administration of rosella flower extract gel with a concentration of 15% effectively reduced the expression of TNF-α and Caspase-3 in mice exposed to UVB light and produced filled and dense collagen. So, it can be concluded that rosella flower extract gel can act as an antioxidant that inhibits the growth of TNF-α and Caspase-3 expression.

Analysis of Skin Protection from the Dangers of Sun Exposure Using Color Variations and Types of Cotton Fabrics

Cotton fabric is a comfortable clothing material to wear in tropical climates. In addition to the comfort aspect, cotton cloth is expected to be able to protect the skin from the dangers of sun exposure. This research was conducted with the aim of knowing the optimum amount of protection produced by cotton cloth, determining the type and color of cotton cloth that is most effectively used as a protector, and knowing the SPF (sun protection factor) value category based on the type and color of cotton cloth. This study used three types of cotton cloth, each consisting of four colors, as well as a Digital Environment Multimeter which was used to measure the intensity of sunlight in units of lux. The protection value is obtained by comparing the intensity of sunlight without a cotton cloth protector (lux) with the intensity of sunlight using a cotton cloth protector (lux). The results obtained show that the most optimum protection value is found in black toyobo cotton cloth with an SPF value of 54.4 and a transmittance of 1.8%. The cotton fabrics that provided the most effective protection based on type and color were black and blue toyobo, medina and Japanese cotton fabrics. Based on the SPF value obtained, it can be seen that black and blue toyobo cotton fabrics, and black madinah cotton fabrics have a very good protection category. The black and blue Japanese cotton fabrics, as well as the blue medina type, have a good protection category, while the orange Toyobo cotton fabrics have a sufficient protection category.

Synthesis and Test of C-Phenylcolics [4] Resorcinilate Octabenzoat Sunblock Activity

Research on the discovery of organic sunblock today continues to be intensively conducted because cases of skin cancer caused by sun exposure continue to increase from year to year. Recently, what is used to protect the skin from the dangers of sun exposure is a sunblock lotion product. This research aims to synthesize and test the new organic C-phenylcolics [4] resorcinaryl octabenzoat compound. This research is pure experimental research by testing sunblock activity using Ultraviolet-Visible Spectrophotometry. The C-phenylcallic [4] resorcinaryl octabenzoate compound was synthesized by the C-phenylcalcid [4] resorcinarene method with benzoyl chloride using a catalyst and pyridine solvent. Characterization of reaction products used infra-red spectrometers and proton-NMR. Meanwhile, testing sunblock activity was conducted in vitro using the ultraviolet spectrometry method. The synthesis results showed that C-phenylcalcid [4] resorcinyl octabenzoat was in the form of a dark yellow solid, melting point of 238-240 oC and yield of 74.10%. The in vitro test results showed that C-methylcolics [4] resorcinyl octabenzoat has a broad spectrum because it can absorb UV B and UV C rays with an SPF value of 30. This compound has the potential to be developed as a sunblock.

Prevalent skin and dermatoses care in older adults treated at a private clinic and its relationship with comorbidities

Abstract Objectives : To identify and assess the prevalence of skin changes in the older adults surveyed, as well as to detect skin phototype according to the Fitzpatrick classification and to assess whether there was an association between the changes identified and predisposing factors (smoking, diabetes mellitus and hypertension). Additionally, evaluate the level of knowledge of the subjects regarding skin care. Method : A cross-sectional study was conducted in April to August 2018, based on a convenience sample of 80 older adults attending a private clinic. A questionnaire was applied among the subjects to identify their skin care and an answer sheet was completed by the researcher with information about the physical examination of the skin. Data were analyzed by the chi square or Fisher’s exact method. Poisson regression was used to determine the independent effect of the exploratory variables on the response variable. Results : The sampled population had a low level of education and was low-income and did not take proper care of their skin, while 70% were skin phototype 4. Most (73%) were aware of what skin cancer is and a significant portion 50% did not use sunscreen or moisturizer. There was no significant difference between the sexes (p>0.05). About half of the older adults reported having been instructed about skin care. Seventy two percent knew about the dangers of sun exposure. The most common skin alteration was melanosis and an association was found between diabetes and keratosis. Conclusions : The study population was low income, with a low level of education. They were exposed to the sun and did not make proper use of sunscreen or moisturizers, but sought health information from their doctor and knew what skin cancer was.

Association of serum vitamin D concentrations with dietary patterns in children and adolescents

BackgroundBecause children have been advised on the dangers of sun exposure, diet is an important contributor of serum 25 hydroxyvitamin D [25(OH)D] concentrations. Aim of this study was to determine whether serum 25(OH)D concentrations were associated with any specific dietary patterns in US children.MethodsData from 2 cycles of National Health and Nutrition Examination Survey (NHANES) 2003–2004 and 2005–2006 for individuals aged 2 to ≤19 y, were used to study relation between dietary patterns and serum 25(OH)D. We derived 2 major dietary patterns based on the food frequency questionnaire data. These were labeled as High-Fat-Low-Vegetable Dietary (HFLVD) pattern and Prudent Dietary (PD) pattern.ResultsIn multivariate adjusted analysis, there was no significant relationship between serum 25(OH)D concentrations and tertiles of HFLVD and PD dietary pattern scores in all subjects, boys, and girls. When dietary patterns scores were used as a continuous variable in adjusted analysis, children (all) with higher PD contribution scores to overall diet showed a significant positive relation with serum 25(OH)D (β = 59.1, P = 0.017). When data were stratified by sex, a significant positive relation was observed in girls between serum 25(OH)D concentration and PD pattern scores (β = 82.1, P = 0.015). A significant negative relation was observed in girls between serum 25(OH)D and HFLVD pattern scores (β = − 88.5, P = 0.016).ConclusionOverall, serum 25(OH)D were associated with PD pattern but not with HFLVD pattern in US children. In public health perspective, it is important to encourage children, especially girls who are consuming HFLVD pattern to shift to healthier diet.

Outdoor work as a risk factor for high-grade cutaneous squamous cell carcinoma of the head and neck.

IntroductionWhile it is clear that individuals with outdoor occupations are at a significantly greater risk of developing cutaneous squamous cell carcinoma (cSCC), no previous studies have investigated the potential association between the tumour grade and occupation in this patient population.AimTo assess occupation as a risk factor for the development of high-grade cSCC. Secondarily, to determine the association between the tumour grade and other clinical characteristics.Material and methodsRetrospective analysis of 256 patients treated for head and neck cSCC at our institution in 2007–2016. The following patient characteristics and variables were assessed: age; sex; tumour location and grade; profession; and education level. A univariate analysis was performed to assess the association between each study variable and grade 3 tumour differentiation.ResultsThe following variables were significantly associated (p < 0.05) with grade 3 (G3) cSCC tumours: outdoor work vs. indoor work; primary school vs. high school education; and age. Additionally, patients with low-grade (G1) tumours were significantly younger (mean age: 72) than patients with high-grade (G3) tumours (mean age: 79) (p = 0.046).ConclusionsTo our knowledge, this is the first study to assess the variables associated with the tumour grade among outdoor workers. These findings suggest that outdoor workers who develop cSCC are at a greater risk of developing more aggressive cancers. These findings provide additional support for classifying cSCC as an occupational disease. Early education about the dangers of sun exposure during the first years of school is essential to minimize the risks of developing high-grade skin cancer.

Perceptions and Practices of the Iranian Population regarding Skin Cancers: A Literature Review.

Despite being preventable, more than 15% of all cancer cases in Iran occur in the skin, making them the most commonly diagnosed malignancy in the country. The purpose of this study is to gain an insight into the current skin cancer related knowledge, attitudes, beliefs, and practices among the Iranian population. A systematic computer based literature search was conducted using databases for articles published through April 2017. Research studies included those that measured skin cancer or sun protection related knowledge, attitudes, beliefs, and behaviors in different Iranian population groups. Exclusion criteria for the articles included (1) irrelevant topics to the review article's aim, (2) articles that focused on the treatment of skin cancers instead of prevention practices, and (3) similar studies conducted on populations not indigenous to Iran. A total of 25 articles that met the eligibility criteria were included in the review. Predominant data were collected via questionnaires. Skin cancer related knowledge varied from low to high across the studies. Moreover, there was a pattern of low perceived skin cancer susceptibility and severity. Overall, there was low usage of sun protection methods among the Iranian population. The findings of this study show that efforts to prevent skin cancer are needed. Education concerning the dangers of sun exposure as well as strategies used to prevent or lower the risk of developing skin cancer should be stressed.

Immediate and long-term effects of ultraviolet radiation on the skin

The potential dangers of sun exposure to skin health, as well as the need for adequate sun protection, are well-documented in the literature. Sun protection has traditionally been seen as the application of chemical or physical sunscreens to the skin; however, a better understanding of skincare, and particularly photoprotective topicals, is affecting expert opinions on the best products to apply to protect against ultraviolet exposure. This paper is an update of a previous paper published by the author in 2013. It discusses the dermal effects of sun exposure and explores ways in which aesthetic nurses can support patients who wish to achieve a healthy glow.

Understanding the dermal effects of heightened exposure to the sun

The potential dangers of sun exposure to skin health, as well as a need for sun protection, are well documented in both the lay and professional press. However, there are variations between UK, EU and US regulations and guidelines, different interpretations of the term ‘sun protection’, and ongoing debate between advisory bodies on the level and frequency of application of sun protection factor (SPF) necessary to offer adequate protection. This article reviews the effects of exposure to ultraviolet radiation, the relevant regulations (including the imminent regulatory changes in the USA), and new ingredients that are making an impact on cosmeceutical sun protection and damage repair.

Behavioral factors of patients before and after diagnosis with melanoma: a cohort study – are sun-protection measures being implemented?

Melanoma is the deadliest form of all skin cancers and is highly linked to sun-related behavior in patients. However, sun-protection behavior to prevent melanoma in this population has been shown to be inadequate to date. The objective of this study was to compare changes in sun protection habit before and after patients' diagnosis with malignant melanoma. The study also seeks patients' advice on how to improve public education on melanoma prevention. A retrospective survey study was conducted on 68 respondents of patients diagnosed with melanoma from six different dermatologic practices in various boroughs of New York and Long Island in the state of New York by telephone interviews. There was a significant positive change in patients' sun-protection behavior after they were diagnosed with melanoma. Various methods of sun protection, such as avoiding sun exposure, applying and reapplying sunscreen, and wearing protective clothing were practiced more frequently after diagnosis. In addition, the frequency of sunbathing decreased drastically. Most patients were aware about the dangers of sun exposure before their diagnosis. They, however, did not feel the need to adopt sun-protection measures before their diagnosis. Respondents advised that education on dangers to excess sun exposure should be provided at an early age through multiple venues. The study reflected that 71% of diagnosed patients who completed the survey were informed about sun protection before their diagnosis. Many patients did not follow strict guidelines to prevent sun damage as shown by their behaviors before diagnosis. Diagnosis of the disease was apparently the main motivating factor to initiate challenging behavioral changes.

Malignant melanoma

There is an increasing public awareness of the dangers of sun exposure and possibility of developing malignant melanoma. Thinning of the ozone layer, global warming and constant media reminders of the risks of exposure to the sun are bringing patients to the surgery at the first sign of a mole or blemish on the skin.

Photoprotection: where do we stand?

Ultraviolet sun radiation can cause several deleterious effects on the skin, including photoaging and carcinogenesis. Physical protection and sunscreens are currently the two main types of photoprotection. Overall, people seem informed about the dangers of sun exposure, but sometimes they are not willing to implement the right sun-protection measures. Sunscreens are reported to be the most frequently used method worldwide, but they cannot substitute physical protection and a proportion of people do not apply them correctly. Public campaigns, together with fashion and the right role models, can still offer a lot in persuading people to change their habits towards a more sun-protected life.

Tanning and sunburn: knowledge, attitudes and behaviour of people in Great Britain

A representative sample of the British population was interviewed to identify the factors associated with sunburn and intention to tan, and the source from which people obtained their information about the risks of sun exposure. As part of its rolling Omnibus survey, the Office for National Statistics interviewed a randomly selected representative sample of 1858 adults (aged 16 or over) in Great Britain in October 1996. The analysis and interpretation of the resulting data form the basis of this study. The response rate was just below 70 per cent. Forty-three per cent of men and 35 per cent of women reported sunburning in the 12 months to October 1996. Factors associated with sunburn were: being male, having a skin that tans with difficulty and being younger. Concerning 'intention to tan', 34 per cent of men and 39 per cent of women admitted trying. There were associations with having a skin that tans easily, and, less strongly, with being younger. There was a clear association between trying to tan and severity of sunburn. Most people identified television as their main source of information about the dangers of sun exposure, and the majority had seen the sunburn forecasts on weather reports. Comparison with a previous Omnibus sunburn survey from 1993 shows little change in the proportion of the population becoming sunburnt, but some increase in the proportion of men intending to tan. The data allow an insight into current sun-related behaviour and whether there has been a change since 1993. Health promotion campaigns warning about the risk from the sun may have increased awareness, but have thus far failed to reduce the proportion becoming sunburnt. It is time to re-evaluate the thinking behind such programmes.

Implications of an Educational Intervention Program Designed to Increase Young Adolescents' Awareness of Hats for Sun Protection

This research examined the content and outcome of an educational intervention program designed to foster sun protective awareness and behaviors among young adolescents. Awareness of sun protection qualities, as well as preferences and stated intention to wear protective clothing, were measured based on young adolescents' responses to selected hat styles both before and after the educational interventions. The educational intervention was well received by this age group (ages 10-12), and a comparison of matched pre- and post-tests (397 girls and boys) indicated an increase in knowledge of sun protective factors in clothing. However, familiarity and past experience with hat styles helped to determine both preference and intent to wear. This finding points to the need to incorporate adolescents' preferences in design and modifications of hats for protection, and to take further measures to encourage protective behaviors in young adolescents' clothing selection. Implementing a standardized sun protection rating system for hats and other types of clothing like those used with sunscreen lotion would begin to familiarize people of all ages with the dangers of sun exposure and the benefits of wearing sun protective clothing.

Trends in sun exposure knowledge, attitudes, and behaviors: 1986 to 1996\\

Background: The American Academy of Dermatology’s national program Melanoma/Skin Cancer Detection and Prevention, developed in response to the rising incidence of invasive melanoma in the United States, has annually during the past decade produced extensive print, radio, and television coverage about the dangers of sun exposure and benefits of sun protection. Objective: We measured the progress achieved in increasing the awareness and knowledge of skin cancer and changing the attitudes, beliefs, and behaviors that affect skin cancer risk. We also describe current sun-related behavior including sunburning, assess the likelihood of practicing sun protection strategies, and provide a baseline against which future changes in sun protection behavior may be evaluated. Methods: A 1996 telephone survey repeated questions used in 1986 to evaluate change and used classifying questions to better define attitudes and behaviors. Results: From 1986 to 1996, the knowledge of the perceived harmful effects of the sun significantly broadened, but the UV exposure behavior as measured by sunburning (30% to 39%) and regular use of a tanning booth (2% to 6%) also increased. There was a decline in the attitude that having a tan was healthy; however, in 1996 having a tan was still considered to enhance appearance, particularly by men. Sunscreen use increased (35% to 53%). Women, younger persons, persons residing in areas with fewer sunny days, and whites were more likely to tan intentionally, but men who lived in the South were more likely to sunburn. Conclusion: During the past decade, the early process of change involving cognitive and emotional activities began. With this study, high-risk population subsets performing specific adverse behavior were identified. In the future, they can be targeted with messages that promote attitudinal and behavioral change.

Summer Sun Exposure: Knowledge, Attitudes, and Behaviors of Midwest Adolescents

Background.Extensive print, radio, and television coverage about the dangers of sun exposure and benefits of sun protection occurred over the past decade. Illinois teen knowledge and attitudes about sun exposure/protection, sun-exposure/protection behavior, and information sources were determined by a summer telephone survey.Methods.Telephone interviews with 658 teenagers between ages 11 and 19 included African-American, Asian, Hispanic, Native American, and white teenagers.Results.Teens knew that too much sun was harmful as it caused skin cancer and sunburn. Sunburn was mentioned more often by those with skin types that burned easily and tanned poorly (I,II) (P< 0.001), was better known to girls than to boys (P< 0.001), and was recognized more by those with higher socioeconomic status (P< 0.001) but was not associated with age. Widely held sun exposure attitudes were socializing with friends and feeling better when outdoors. On weekdays, boys averaged 5.3 hr (SD, 1.65 hr) outside compared with 3.9 hr (SD, 0.75 hr) for girls (P< 0.001). Teenage boys were more likely to obtain occupational sun exposure, and girls sunbathed. Subjects with skin types I and II reported an average of 3.3 sunburns in the past year. During unprotected sun exposure, extensive numbers of teens with moderate-risk skin type experienced at least 1 sunburn per year. Indoor tanning use was more prevalent among older girls and those with skin types I and II. Sunscreen use was associated with water recreational activities (swimming, water sports, and going to the beach) by girls slightly more than by boys (P< 0.001). Hat-wearing was more common among boys than among girls.Conclusions.Teen knowledge that excessive sun exposure causes skin cancer and sunburns and that wearing sunscreens and hats were sun-protective methods did not enable sun protection that prevented burning. This is particularly troublesome because severe sunburns in youth are associated with an increased risk of melanoma. Existing teen sunscreen use could be broadened by educating teens to use adequate quantities of sunscreen prior to daily sun exposure to prevent painful burns. Messages to teens that emphasize the short-term consequences of painful sunburns because of inadequate protection during outdoor occupational and non-water-related recreational exposure would increase the relevance of the message and may enable behavioral change. Parents and physicians need to be included in messages that are directed to teens and to become part of their education. Parents could ensure an adequate sunscreen supply for daily use by the family, encourage teens not to deliberately tan, and serve as role models for the use of protective clothing.

Nonmelanoma skin cancer.

Preview Heightened awareness and early diagnosis of skin cancer are vital for timely treatment. Primary care physicians who can recognize malignant and premalignant lesions of the skin have an important role in improving cure rates, limiting morbidity, and decreasing healthcare costs. The authors discuss management of basal cell and squamous cell carcinomas, emphasizing risk factors and patient education.

Childhood melanoma in Australia.

Data from a population-based registry, the Australian Paediatric Cancer Registry, were used to determine the incidence of malignant melanoma in children under 15 years of age in Australia. Over a 17-year period, 217 cases were identified. For the period 1977-89 inclusive, the annual age incidence was 0.34 per 100,000. There was some variation in incidence between the different states with Queensland recording the highest incidence at 0.97 per 100,000, the highest reported incidence in the world for childhood melanoma. Most of the cases occurred in children aged 13 or 14 years old with girls affected slightly more often, the sex ratio being 0.92. There was a statistically significant seasonal variation with fewer cases being diagnosed during the winter months. The commonest site was the trunk. Two of the cases were second neoplasms. This series demonstrates the need for increased education of children living in tropical and subtropical regions about the dangers of sun exposure and of methods of reducing exposure. Children who have undergone chemotherapy appear to be at particular risk.
