Worksite Cancer Prevention Activities in the National Comprehensive Cancer Control Program.

Workplaces are one setting for cancer control planners to reach adults at risk for cancer and other chronic diseases. However, the extent to which Centers for Disease Control and Prevention-funded National Comprehensive Cancer Control Programs (NCCCP) implement interventions in the workplace setting is not well characterized. We conducted a qualitative content analysis of program action plans submitted by NCCCP grantees from 2013 to 2015 to identify and describe cancer prevention objectives and interventions in the workplace setting. Nearly half of NCCCP action reports contained at least one cancer prevention objective or intervention in the workplace setting. Common interventions included education about secondhand smoke exposure in the workplace, and the importance of obtaining colorectal cancer screening. Workplace interventions were relatively common among NCCCP action plans, and serve as one way to address low percentages of CRC screening, and reduce risk for obesity- and tobacco-related cancers.

Melatonin and its metabolites ameliorate ultraviolet B-induced damage in human epidermal keratinocytes.

We investigated the protective effects of melatonin and its metabolites: 6-hydroxymelatonin (6-OHM), N1-acetyl-N2-formyl-5-methoxykynuramine (AFMK), N-acetylserotonin (NAS), and 5-methoxytryptamine (5-MT) in human keratinocytes against a range of doses (25, 50, and 75 mJ/cm2) of ultraviolet B (UVB) radiation. There was significant reduction in the generation of reactive oxygen species (50-60%) when UVB-exposed keratinocytes were treated with melatonin or its derivatives. Similarly, melatonin and its metabolites reduced the nitrite and hydrogen peroxide levels that were induced by UVB as early as 30 min after the exposure. Moreover, melatonin and its metabolites enhanced levels of reduced glutathione in keratinocytes within 1 hr after UVB exposure in comparison with control cells. Using proliferation assay, we observed a dose-dependent increase in viability of UVB-irradiated keratinocytes that were treated with melatonin or its derivatives after 48 hr. Using the dot-blot technique and immunofluorescent staining we also observed that melatonin and its metabolites enhanced the DNA repair capacity of UVB-induced pyrimidine photoproducts (6-4)or cyclobutane pyrimidine dimers generation in human keratinocytes. Additional evidence for induction of DNA repair in cells exposed to UVB and treated with the indole compounds was shown using the Comet assay. Finally, melatonin and its metabolites further enhanced expression of p53 phosphorylated at Ser-15 but not at Ser-46 or its nonphosphorylated form. In conclusion, melatonin, its precursor NAS, and its metabolites 6-OHM, AFMK, 5-MT, which are endogenously produced in keratinocytes, protect these cells against UVB-induced oxidative stress and DNA damage.

Analysis of patient preferences on patient-provider interactions through the OpenNotes online portal in dermatology.

Background: Many medical centers are beginning to use OpenNotes (ON) to empower patients. However, there is a lack of literature reviewing the ON system in dermatology and any differences in attitudes between men and women. If so, it is uncertain what concerns are more important to female patients. Given the complex lexicon of notes in dermatology, the outpatient setting of dermatology practices, and the often-complex nature of treatment regimens, investigation was merited. Objective: This paper aimed to evaluate a survey of dermatologic patients on their attitudes toward the ON system. Methods: From July through October 2015, 333 dermatologic patients at the Beth Israel Deaconess Medical Center completed an anonymous, voluntary, 25-question survey of the ON system while in the waiting room. Approximately 60% of respondents were female and 40% were male. Respondents were older, with 27% age >65 years, 21% between 56 and 65 years, 16% between 46 and 55 years, 17% between 36 and 45 years, 14% between 26 and 35 years, and 4% between 18 and 25 years. Eighty-five percent of respondents were white, and 73% had, at minimum, graduated from college. Results: Patient response to ON was positive, with 93% agreeing ON is a good idea. Of the patients who accessed their own notes (69% of respondents), 99.6% desired continued access. In addition, 85.6% of patients felt ON allowed them to control their own health, and 70% reported increased confidence in their dermatologist. Nineteen percent of respondents thought ON presented a privacy concern. Conclusion: The results showed that female patients strongly desire access to their medical records, but concerns about privacy and security exist. Preliminary analysis by a statistician did not find any statistically significant variations between men and women within the results of the survey. Due to the wide agreement in responses, it is unlikely that there are significant differences in opinion on ON between men and women.

The dermatological aspects of hEDS in women.

Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders that may present with a wide range of multisystemic symptoms. Hypermobile EDS, one of 13 identified subtypes of EDS, is the only variant without a known associated genetic mutation. A review of the literature suggests the five primary dermatological changes associated with hypermobile EDS are soft skin, atrophic cutaneous scars, piezogenic papules, hyperextensive stretchability, and hematomas. Our paper will address these cutaneous manifestations and delve into how they affect patients (primarily women). Possible consequences and treatment options for these different dermatological changes, as well as other skin manifestations such as livedo reticularis and elastosis perforans serpiginosa, will also be further explored.

Dermacentor variabilis: regulation of fibroblast migration by tick salivary gland extract and saliva.

We examined the effects of tick SGx and saliva on basal- and platelet-derived growth factor (PDGF)-stimulated cell migration and extracellular signal-regulated kinase (ERK) signaling in fibroblasts. Repair of injured monolayers was delayed by SGx pretreatment and was not associated with reductions in cell number. In migration assays, SGx suppressed both basal- and PDGF-stimulated fibroblast movement. Furthermore, SGx and saliva reduced PDGF-stimulated ERK activity. Thus, the delayed repair of monolayer injuries resulted from SGx inhibiting fibroblast migratory responses to chemotactic signals. SGx also suppressed injury- and growth factor-induced ERK activation in renal epithelial OK cells. Our data suggest that maintenance of the tick feeding lesion results, in part, from suppressing ERK signaling and fibroblast migration, events playing integral roles in the wound healing response. The effects of SGx on cells not involved in wound healing suggest that a constituent(s) in tick saliva has global effects on the ERK signaling pathway.

Immunomodulating Agents as Antipruritics.

Chronic pruritus, or itch lasting greater than 6 weeks, is an increasingly common and debilitating medical problem. Recent studies have unveiled previously unrecognized neuroimmune axes whereby inflammatory cytokines act directly on the nervous system to promote itch. Thus, the emergence of newer targeted biologic therapies has generated the possibility of novel treatment strategies for chronic itch disorders. This article reviews the pathophysiology of multiple chronic itch disorders, including atopic dermatitis, chronic idiopathic pruritus, chronic urticaria, and prurigo nodularis. Furthermore, new and emerging immunomodulatory therapies that will likely alter current treatment paradigms are discussed.
