A rare case of invasive melanoma likely arising from passenger melanocytes of a basal cell carcinoma.

Neoplasms consisting of different cell lineages within a single skin specimen are rare, yet well documented in the literature. However, to date, there appears to be no report of invasive melanoma arising directly from the passenger melanocytes of a basal cell carcinoma (BCC). We present a case of a 91-year-old male with a suspicious lesion on the ear.

Exploring Social Media Group Use Among Breastfeeding Mothers: Qualitative Analysis.

Background: Breastfeeding is well known as the optimal source of nutrition for the first year of life. However, suboptimal exclusively breastfeeding rates in the United States are still prevalent. Given the extent of social media use and the accessibility of this type of peer-to-peer support, the role of social networking sites in enabling and supporting breastfeeding mothers needs to be further explored.

Utilization of online focus groups to include mothers: A use-case design, reflection, and recommendations.

Advances in technology over the past decade have allowed unique methodologies to emerge, enabling the engagement of hard-to-reach populations on sensitive topics in a way that was before thought not possible with traditional face-to-face modalities. This study aimed to use online focus group discussions (FGDs) to explore breastfeeding mothers' use of social media. Results indicate participants had a positive experience with online FGDs, and almost all preferred this method to traditional face-to-face focus groups.

A Physician's Recommendation for Human Papillomavirus Vaccination: What Makes African-American Mothers Compliant?

Background: Improving human papillomavirus (HPV) vaccination among African-American (AA) female adolescents to reduce the cervical cancer burden is important and cost-effective. The study objective is to identify factors most influential to AA mothers' likelihood to comply with a physician's recommendation to get their daughters the HPV vaccine.

Methods: We conducted a cross-sectional survey.

Development of a Theory-based, Sociocultural Instrument to Assess Black Maternal Intentions to Vaccinate Their Daughters Aged 9 to 12 Against HPV.

The human papillomavirus (HPV) vaccine could assist in reducing the cervical cancer disparity existing between Black and White women. Understanding factors influencing Black maternal intentions to vaccinate their daughter is essential in improving vaccination uptake. However, existing instruments do not comprehensively assess factors (e.

Social modeling influences and alcohol consumption during the first semester of college: a natural history study.

The authors examine both the alcohol consumption pattern of freshmen students during their first semester and the degree to which social modeling of peer behavior impacts consumption. A total of 534 students, residing on campus, were prospectively examined at four 30-day intervals. Data were evaluated on the basis of age, gender, and the effects of time using generalized estimating equations (GEEs).

Challenges and recommendations to enforcement of alcohol policies on college campuses: an administrator's perspective.

Objective: The purpose of this study was to examine challenges and recommendations (identified by college administrators) to enforcing alcohol policies implemented at colleges in the southeastern United States.

Methods: Telephone interviews were conducted with 71 individuals at 21 institutions.

Results: Common challenges included inconsistent enforcement, mixed messages received by students, and students' attitudes toward alcohol use.

Validation of the Drinking Context Scale (DCS-9) for use with non-adjudicated first-year college students.

The Drinking Context Scale (DCS-9) has been used to measure the impact of drinking during social, emotional, and situational contexts. Psychometric properties remain unevaluated in a population of non-adjudicated first-year college students in the southeast. Liseral 8.

Brief report: Aggressive challenging behaviour in adults with intellectual disability following community resettlement.

Background: Aggressive challenging behaviour is common in adults with intellectual disability (ID) in long-term care facilities. The government's commitment to the closure of all facilities in England has led to concerns over how to manage this behaviour in the community. The aim of this study was to assess changes in aggressive challenging behaviour and psychotropic drug use in adults with ID following resettlement using a person-centred approach.

Validation of the College Alcohol Problem Scale-revised (CAPS-r) for use with non-adjudicated first-year students.

First-year students in transition to college are at increased risk for consuming greater amounts of alcohol and are subject to subsequent alcohol-related problems. The 8-item College Alcohol Problem Scale-revised (CAPS-r) has been used to measure alcohol-related problems in adjudicated undergraduates and psychology majors. However, structural validity of the CAPS-r has not been examined in a general first-year student population.

A Solitary Neck Nodule as Late Evidence of Recurrent Lobular Breast Carcinoma.

Recurrent lobular breast carcinoma manifesting as a cutaneous neck nodule in a woman, 14 years after successful chemotherapy, illustrates the importance of following at-risk patients with a high level of clinical suspicion. This case emphasizes the value of combining clinical findings with appropriate histopathologic and immunohistochemical analysis when evaluating a cutaneous lesion in such a patient.

Drinking likelihood, alcohol problems, and peer influence among first-year college students.

Excessive alcohol consumption is a predominant health concern on college campuses in the United States. A stepwise multiple regression analysis was used to examine the predictive values of demographic factors in relation to alcohol subscales (Drinking Context Scale, College Alcohol Problems Scale-revised, and Social Modeling Scale) with the outcome of number of drinking days in the past 30 days among a sample (n = 224) of first-year college students. The final model predicted 37.

Role of biomarkers in incisional hernias.

Incisional hernias represent one of the most common complications of laparotomies. Previous investigations have suggested that a disorder in collagen fiber structure and production level may be an important pathologic cause of abdominal wall hernias. We hypothesized that a cross-examination of multiple extracellular matrix biomarkers might identify underlying defects contributing to the development of hernias.

A randomized study of four cards designed to prevent problems during college students' 21st birthday celebrations.

Objective: The purpose of this study was to examine the efficacy of sending cards designed to prevent alcohol-related problems during 21st birthday celebrations.

Method: College students were randomly assigned to receive cards with one of the following messages: (1) a neutral birthday greeting; (2) harm reduction information; (3) messages designed by the Be Responsible About Drinking (B.R.

Reversal by green light of blue light-stimulated stomatal opening in intact, attached leaves of Arabidopsis operates only in the potassium-dependent, morning phase of movement.

Green light reversal of blue light-stimulated stomatal opening was discovered in isolated stomata. The present study shows that the response also occurs in stomata from intact leaves. Arabidopsis thaliana plants were grown in a growth chamber under blue, red and green light.

TRUCE for advocacy and peer education in tobacco prevention.

In response to aggressive marketing of tobacco to college students, Florida's legislature allocated multi-settlement agreement dollars to fund tobacco prevention programming at state institutions of higher learning. The Student Tobacco Reform Initiative: Knowledge for Eternity (STRIKE) was one such program. Its purpose was to increase awareness and support college student advocacy for prevention.

Drinking locations prior to impaired driving among college students: implications for prevention.

Drinking and driving is perhaps the most serious problem associated with heavy drinking among college students in the United States. In this study, the authors examined drinking locations prior to impaired driving in a college student sample. They administered the Impaired Driving Assessment to 91 college students identified as high risk for drinking and driving.

The blue light-specific response of Vicia faba stomata acclimates to growth environment.

Stomata in epidermal strips from growth chamber-grown Vicia faba leaves opened less in response to white light than did stomata from greenhouse-grown leaves. Chlorophyll-mediated, red light-stimulated opening was similar in stomata from the two growth conditions, but stomata from the growth chamber environment had a severely reduced response to blue light. Transfer of plants between the two growth conditions resulted in an acclimation of the stomatal blue light response.

Improving nurse staffing measures: discharge day measurement in "adjusted patient days of care".

Previous research cannot account for the discrepancy between registered nurse (RN) reports of understaffing and studies showing slight improvement. One reason may be that "adjusted patient days of care" (APDC) underestimates patient load. Using data from all Pennsylvania acute care general hospitals for the years 1994 through 1997, we found that APDC is underestimated by two hours.

Blue light and phytochrome-mediated stomatal opening in the npq1 and phot1 phot2 mutants of Arabidopsis.

Recent studies have shown that blue light-specific stomatal opening is reversed by green light and that far-red light can be used to probe phytochrome-dependent stomatal movements. Here, blue-green reversibility and far-red light were used to probe the stomatal responses of the npq1 mutant and the phot1 phot2 double mutant of Arabidopsis. In plants grown at 50 micromol m-2 s-1, red light (photosynthetic)-mediated opening in isolated stomata from wild type (WT) and both mutants saturated at 100 micromol m-2 s-1.

Relative humidity is a key factor in the acclimation of the stomatal response to CO(2).

Previous work has shown that stomata of growth chamber-grown Vicia faba leaves have an enhanced CO2 response when compared with stomata of greenhouse-grown plants. This guard cell response to CO2 acclimatizes to the environmental conditions on the transfer of plants between the two environments. In the present study, air relative humidity is identified as a key environmental factor mediating the changes in stomatal sensitivity to CO2.
