Introduction Discovery of novel drugs, treatments, and testing of consumer products in the field of dermatology is a multi-billion dollar business. Due to the distressing nature of many dermatological diseases, and the enormous consumer demand for products to reverse the effects of skin photodamage, aging, and hair loss, this is a very active field. Areas covered In this paper, we will cover the use of animal models that have been reported to recapitulate to a greater or lesser extent the features of human dermatological disease. There has been a remarkable increase in the number and variety of transgenic mouse models in recent years, and the basic strategy for constructing them is outlined. Expert opinion Inflammatory and autoimmune skin diseases are all represented by a range of mouse models both transgenic and normal. Skin cancer is mainly studied in mice and fish. Wound healing is studied in a wider range of animal species, and skin infections such as acne and leprosy also have been studied in animal models. Moving to the more consumer-oriented area of dermatology, there are models for studying the harmful effect of sunlight on the skin, and testing of sunscreens, and several different animal models of hair loss or alopecia.
This study examined the association between sex, study risks and willingness to participate in research among a community sample of African Americans. We hypothesized that African American males would be more willing to participate in studies involving both minimal and greater-than-minimal risk. The study sample was recruited through a community engagement program (HealthStreet). Interviewers obtained information on socio-demographic variables and willingness to participate in various research types. We categorized research types into minimal risk and greater-than-minimal risk based on the IRB classification. The study sample comprised 6544 African-Americans; 58.4% were females. About 92.6% of the participants were willing to participate in surveys and 58.1% in research requiring medication use. More males would participate in minimal risk studies requiring review of medical records (males 87.0% vs. females 84.2%, p = 0.0021) and studies involving giving a blood sample (males 84.2% vs. females 81.7%, p = 0.0083). Also, more males would participate in greater than minimal risk studies involving the use of medication (60.5% v. 56.3% p = 0.0007). More males were willing to participate in minimal risk studies (studies involving the review of medical records and giving blood samples) and greater-than-minimal risk study involving the use of medication.
Introduction Older adults, including racial and ethnic minorities, are underrepresented in research. As the US population ages, the number of older racial and ethnic minority individuals will increase. Including these individuals in research is an important step towards reducing health disparities. Methods We used data from HealthStreet, a University of Florida community engagement program which uses community health workers to assess the health of the community, to assess willingness to participate in different types of health research by race/ethnicity. Descriptive statistics and logistic regression models were used to assess willingness to participate among adults aged 50 and older, by race/ethnicity (n = 4694). Results Our sample was 42.0% non-Hispanic White, 52.8% non-Hispanic Black, and 5.2% Hispanic. Non-Hispanic White participants reported more past research participation than non-Hispanic Black and Hispanic participants (28.7% vs. 19.0% and 19.2%, respectively). Compared with non-Hispanic White participants, non-Hispanic Black participants were less willing to participate in most types of studies, while Hispanic participants were less willing to participate in studies that might be seen as invasive (required blood sample, genetic sample, or participants to take medicine, or use of medical equipment). Conclusions Our study provides investigators with a general profile of research preferences by race/ethnicity; compared with non-Hispanic White individuals, non-Hispanic Black individuals are less willing to participate in most studies, while Hispanic individuals are less willing to participate in studies that may be seen as invasive or demanding. It is imperative to include diverse older adults in health research. By tailoring research based on preferences we can improve recruitment in underrepresented populations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
