Abstract
This research is a case study of a 34-year-old patient that presented with a right breast lump measuring 1.9cm found to have invasive mammary carcinoma. Diagnostic mammogram and ultrasound were followed by ultrasound guided breast biopsy to make the diagnosis.
Breast cancer is the leading cause of cancer-related death in women between the ages of 15-39 inthe United States. Annual mammograms are recommended to begin at age 40, therefore younger women often do not have mammograms or breast ultrasounds unless they have symptoms. As a result, younger women are often diagnosed with breast cancer at a later stage with a poor prognosis. In many cases, the diagnosis an invasive breast cancer. Invasive breast cancer is a term that is used to describe a cancer that has invaded or infiltrated the surrounding healthy tissue. Patients with this diagnosis undergo more aggressive treatments to improve outcomes. Invasive mammary carcinoma is breast cancer that has features of both ductal carcinoma and lobular carcinoma; thus is considered a mixed tumor. Invasive mammary carcinoma typically begins as a ductal carcinoma that has spread to the surrounding lobules of the breast.

Reasons for Low Pandemic H1N1 2009 Vaccine Acceptance within a College Sample
This study examined health beliefs associated with novel influenza A (H1N1) immunization among US college undergraduates during the 2009-2010 pandemic. Undergraduates (ages 18–24 years) from a large Midwestern University were invited to complete an online survey during March, 2010, five months after H1N1 vaccines became available. Survey items measured H1N1 vaccine history and H1N1-related attitudes based on the health belief literature. Logistic regression was used to identify attitudes associated with having received an H1N1 vaccine, and thematic analysis of student comments was conducted to further understand influences on vaccine decisions. Among the 296 students who participated in the survey, 15.2% reported having received an H1N1 vaccine. In regression analysis, H1N1 immunization was associated with seasonal flu vaccine history, perceived vaccine effectiveness, perceived obstacles to vaccination, and vaccine safety concerns. Qualitative results illustrate the relationship of beliefs to vaccine decisions, particularly in demonstrating that students often held concerns that vaccine could cause H1N1 or side effects. Vaccine safety, efficacy, and obstacles to immunization were major considerations in deciding whether to accept the H1N1 pandemic vaccine. Therefore, focusing on those aspects might be especially useful in future vaccine efforts within the college population
Research in brief : using mobile phones to collect daily experience data from college undergraduates
This research brief describes our recent efforts collecting daily experience data from college undergraduates at a large midwestern U.S. university through mobile phone text messaging. By daily experience data, we mean data that are collected at multiple points from individuals within their natural context, over a period of time. This approach to data collection provides a way to study phenomena under the conditions in which they naturally occur and to examine how those phenomena progress over time or across contexts (Bolger, Davis, & Rafaeli, 2003).--Page 343

Forgone injury treatment among young adult skateboarders
Adolescents and young adults have high levels of forgone healthcare relative to other age groups, placing those who participate in action sports at particularly high risk for untreated injuries. Because skateboard injury data typically involves treated injuries, research to understand unmet health needs in non-clinical samples is needed. This exploratory study used qualitative content analysis of survey and structured interviews with young adult skateboarders (n = 26, mean age = 22.9 years) recruited at skate parks in a small U.S. city to examine the degree, type, and reported reasons for untreated skateboard injuries in that population. Participants completed a paper survey followed by a structured interview regarding their untreated skateboard injuries and reasons for avoiding medical treatment. A majority of respondents (80.8%) described at least one skateboarding injury that they did not have medically treated but now believe they should have done so. Injury types were deep soft tissue injuries (50.0% of respondents), bone fractures (15.4%), concussions (11.5%), and superficial soft tissue injuries (3.8%). Of respondents who avoided treatment, 76.2% considered treatment unnecessary at the time, 38.1% cited avoiding treatment due to cost, and 23.8% cited lack of knowledge. Findings suggest a need to address forgone injury care among young adult skateboarders through increased support and knowledge regarding when and how to seek affordable medical treatment
Young Adults' COVID-19 Testing Intentions: The Role of Health Beliefs and Anticipated Regret
This article is made available for unrestricted research re-use and secondary analysis in any form or by any means with acknowledgement of the original source. These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemic.Purpose
Young adults are at high risk for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and transmission due to their social behaviors. The purpose of this study was to determine their attitudes toward coronavirus disease 2019 (COVID-19) testing, an important approach for minimizing infection and transmission.
Methods
One hundred seventy eight US individuals aged 19–25 years completed an online survey measuring COVID-19 health beliefs and testing intentions. Multivariable logistic regression evaluated the association of heath belief measures (perceived COVID-19 susceptibility, COVID-19 severity, barriers and benefits to testing, and social concerns) with testing intentions.
Results
Most respondents (86.0%) intended to accept a COVID-19 test if recommended by a health professional. High social concern and low perceived obstacles were associated with intent to get tested.
Conclusions
In this sample, most young adults intended to accept COVID-19 testing. Health beliefs predicted testing intention and point to possible intervention approaches to increase willingness to accept COVID-19 testing
The Association between sensation seeking and well-being among college-attending emerging adults
Sensation seeking is a known risk factor for unsafe and reckless behavior among college students, but its association with well-being is unknown. Given that exploration plays an important psychosocial role during the transition to adulthood, we examined the possibility that sensation seeking is also associated with psychological wellbeing. In a large multisite US college sample (N = 8,020), scores on the Arnett Inventory of Sensation Seeking were positively associated with risk behavior, psychological well-being, and eudaimonic well-being. When sensation seeking dimensions were examined separately, well-being was found to be associated with high novelty seeking but with low intensity seeking
Cannabinoid CB2 Receptors in a Mouse Model of A beta Amyloidosis: Immunohistochemical Analysis and Suitability as a PET Biomarker of Neuroinflammation
In Alzheimer\u27s disease (AD), one of the early responses to A beta amyloidosis is recruitment of microglia to areas of new plaque. Microglial receptors such as cannabinoid receptor 2 (CB2) might be a suitable target for development of PET radiotracers that could serve as imaging biomarkers of A beta-induced neuroinflammation. Mouse models of amyloidosis (J20APPswe/ind and APPswe/PS1 Delta E9) were used to investigate the cellular distribution of CB2 receptors. Specificity of CB2 antibody (H60) was confirmed using J20APPswe/ind mice lacking CB2 receptors. APPswe/PS1 Delta E9 mice were used in small animal PET with a CB2-targeting radiotracer, [C-11]A836339. These studies revealed increased binding of [C-11]A836339 in amyloid-bearing mice. Specificity of the PET signal was confirmed in a blockade study with a specific CB2 antagonist, AM630. Confocal microscopy revealed that CB2-receptor immunoreactivity was associated with astroglial (GFAP) and, predominantly, microglial (CD68) markers. CB2 receptors were observed, in particular, in microglial processes forming engulfment synapses with A beta plaques. In contrast to glial cells, neuron (NeuN)-derived CB2 signal was equal between amyloid-bearing and control mice. The pattern of neuronal CB2 staining in amyloid-bearing mice was similar to that in human cases of AD. The data collected in this study indicate that A beta amyloidosis without concomitant tau pathology is sufficient to activate CB2 receptors that are suitable as an imaging biomarker of neuroinflammation. The main source of enhanced CB2 PET binding in amyloid-bearing mice is increased CB2 immunoreactivity in activated microglia. The presence of CB2 immunoreactivity in neurons does not likely contribute to the enhanced CB2 PET signal in amyloid-bearing mice due to a lack of significant neuronal loss in this model. However, significant loss of neurons as seen at late stages of AD might decrease the CB2 PET signal due to loss of neuronally-derived CB2. Thus this study in mouse models of AD indicates that a CB2-specific radiotracer can be used as a biomarker of neuroinflammation in the early preclinical stages of AD, when no significant neuronal loss has yet developed
Learning theories and tools for the assessment of core nursing competencies in simulation: A theoretical review
Aim: To identify the theories used to explain learning in simulation and to examine
how these theories guided the assessment of learning outcomes related to core
competencies in undergraduate nursing students.
Background: Nurse educators face the challenge of making explicit the outcomes of
competency-based education, especially when competencies are conceptualized as
holistic and context dependent.
Design: Theoretical review.
Data Sources: Research papers (N = 182) published between 1999–2015 describing
simulation in nursing education.
Review Methods: Two members of the research team extracted data from the
papers, including theories used to explain how simulation could engender learning
and tools used to assess simulation outcomes. Contingency tables were created to
examine the associations between theories, outcomes and tools.
Results: Some papers (N = 79) did not provide an explicit theory. The 103 remaining
papers identified one or more learning or teaching theories; the most frequent
were the National League for Nursing/Jeffries Simulation Framework, Kolb’s theory
of experiential learning and Bandura’s social cognitive theory and concept of selfefficacy.
Students’ perceptions of simulation, knowledge and self-confidence were
the most frequently assessed, mainly via scales designed for the study where they
were used. Core competencies were mostly assessed with an observational
approach.
Conclusion: This review highlighted the fact that few studies examined the use of
simulation in nursing education through learning theories and via assessment of core
competencies. It also identified observational tools used to assess competencies in
action, as holistic and context-dependent constructs
Dopamine transporters are markedly reduced in Lesch-Nyhan disease in vivo.
Dopamine (DA) deficiency has been implicated in Lesch-Nyhan disease (LND), a genetic disorder that is characterized by hyperuricemia, choreoathetosis, dystonia, and compulsive self-injury. To establish that DA deficiency is present in LND, the ligand WIN-35,428, which binds to DA transporters, was used to estimate the density of DA-containing neurons in the caudate and putamen of six patients with classic LND. Comparisons were made with 10 control subjects and 3 patients with Rett syndrome. Three methods were used to quantify the binding of the DA transporter so that its density could be estimated by a single dynamic positron emission tomography study. These approaches included the caudate- or putamen-to-cerebellum ratio of ligand at 80-90 min postinjection, kinetic analysis of the binding potential [Bmax/(Kd x Vd)] using the assumption of equal partition coefficients in the striatum and the cerebellum, and graphical analysis of the binding potential. Depending on the method of analysis, a 50-63% reduction of the binding to DA transporters in the caudate, and a 64-75% reduction in the putamen of the LND patients was observed compared to the normal control group. When LND patients were compared to Rett syndrome patients, similar reductions were found in the caudate (53-61%) and putamen (67-72%) in LND patients. Transporter binding in Rett syndrome patients was not significantly different from the normal controls. Finally, volumetric magnetic resonance imaging studies detected a 30% reduction in the caudate volume of LND patients. To ensure that a reduction in the caudate volume would not confound the results, a rigorous partial volume correction of the caudate time activity curve was performed. This correction resulted in an even greater decrease in the caudate-cerebellar ratio in LND patients when contrasted to controls. To our knowledge, these findings provide the first in vivo documentation of a dopaminergic reduction in LND and illustrate the role of positron emission tomography imaging in investigating neurodevelopmental disorders
