Abstract
Young women breast cancer survivors face unique challenges in navigating diagnosis and treatment information while also navigating their own life demands (i.e., fertility, childcare, careers). Special consideration to printed and online cancer educational materials distributed to young women should be evaluated for their suitability, but few studies have investigated the educational preferences and needs of young women cancer survivors. We sought to explore young women breast cancer survivors' needs and preferences regarding cancer educational material from diagnosis to survivorship. We used a qualitative design with convenience sampling of young women breast cancer survivors who completed active treatment at a medical center within the last 5 years to participate in semi-structured online focus groups from November 2020 to May 2021. Thirty-three young women (75.8% White, 12.1% Black, 12.1% other) participated in one of seven online focus groups, each lasting approximately 2 h. Four dominant themes emerged from the data: (1) initial interaction with online materials; (2) reasons for seeking printed and online materials; (3) disconnection of visuals; and (4) recommendations. Our findings revealed that young women were initially hesitant to seek online information, but later sought printed and online information after specific endorsement of materials. Current breast cancer materials lack content specific to young women's needs (i.e., reconstruction options), and graphics have little age and racial diversity. Oncology nurses may consider novel methods of education delivery, such as short videos to be shared easily on social media for specific content like scarring results and reconstruction options.

Abstract
Young women (18-45 years of age) with breast cancer often view the end of active treatment as a significant milestone. While completing treatment is largely celebrated, little is known about the immediate time after completing active treatment. The purpose of this qualitative, descriptive study was to explore the needs of young women survivors transitioning out of active breast cancer treatment and into survivorship. We used a qualitative design with convenience sampling of young women who completed active breast cancer treatment within the last 5 years to participate in semi-structured online focus groups from November 2020 to May 2021. Thematic analysis was used to reveal the needs as women transitioned out of active treatment and into survivorship. Thirty-three young women breast cancer survivors (75.8% White, 12.1% Black, 12.1% other) participated in 7 online focus groups each lasting approximately 90 min. Three dominant themes with accompanying subthemes emerged from the data: (1) "feeling like a different kind of woman" (physical [cognitive, weight, sexual] changes, emotional changes [defining normal, loss of purpose]); (2) lingering emotional trauma (active treatment, survivorship); and (3) recommendations (services needed, content needed). Participants in this study did not feel prepared for the physical and emotional changes associated with the transition from active treatment and into survivorship as identified in our 2 main themes of "feeling like a different kind of woman" and lingering emotional trauma. Participants recommended more thorough communication about expectations in survivorship focusing on physical aspects like cognitive, weight, and sexual changes as well emotional challenges like loss of identity in survivorship. More communication specific to young women could assist in the transition to survivorship.

Abstract
Educational print materials for young women breast cancer survivors (YBCS) are supplemental tools used in patient teaching. However, the readability of the text coupled with how well YBCS understand or act upon the material are rarely explored. The purpose of this study was to assess the readability, understandability, and actionability of commonly distributed breast cancer survivorship print materials. We used an environmental scan approach to obtain a sample of breast cancer survivorship print materials available in outpatient oncology clinics in the central region of a largely rural Southern state. The readability analyses were completed using the Flesch-Kincaid (F-K), Fry Graph Readability Formula (Fry), and Simple Measure of Gobbledygook (SMOG). Understandability and actionability were analyzed using Patient Education Materials Assessment Tool for Printable Materials (PEMAT-P). The environmental scan resulted in a final sample of 14 materials. The mean readability of the majority of survivorship materials was "difficult," but the majority scored above the recommended 70% in both understandability and actionability. The importance of understandability and actionability may outweigh readability results in cancer education survivorship material. While reading grade level cannot be dismissed all together, we surmise that patient behavior may hinge more on other factors such as understandability and actionability. Personalized teaching accompanying print material may help YBCS comprehend key messages and promote acting upon specific tasks.

Abstract
BACKGROUND Occurring in up to 40% of all patients with cancer, the incidence of brain tumors has caused limited survival, a high psychosocial burden, and an increase in the loss of decision-making capability for the unique population. Although specific symptoms depend on the type of brain tumor, a clinical team of physicians, nurses, and other individuals commonly assist patients and their caregivers with how to tackle the upcoming challenges of their diagnosis. Despite the support from clinical team members, many patients and caregivers may still seek outside support through social media to process their emotions and seek comfort outside of the clinical setting. Specifically, online resources such as Reddit are used where users are provided with the anonymity they need to show their true behavior without fear of judgment. In this study, we aimed to examine trends from Reddit discussion threads on brain tumors to identify areas of need in patient care. OBJECTIVE Our primary aims were to determine the type of Reddit user posting, classify the specific brain tumors that were the subject of the posts, and examine the content of the original posts. METHODS We used a qualitative descriptive design to understand patients' and caregivers' unmet and met needs. We selected posts from the top-rated 100 posts from the r/braincancer subreddit from February 2017 to June 2020 to identify common themes using content analysis. RESULTS The qualitative content analysis revealed how Reddit users primarily used the forum as a method to understand and process the emotions surrounding a brain tumor diagnosis. Three major topic areas from content analysis emerged as prominent themes, including (1) harnessing hope, (2) moving through the grief process, and (3) expressing gratitude toward other Reddit users. Most of the authors of the posts were patients with brain tumors (32/88, 36%) who used Reddit as a reflective journaling tool to process the associated emotions of a challenging diagnosis. CONCLUSIONS This study shows the potential of Reddit to serve as a unique group therapy platform for patients affected by brain tumors. Our results highlight the support provided by the Reddit community members as a unique mechanism to assist cancer survivors and caregivers with the emotional processing of living with brain tumors. Additionally, the results highlight the importance of recommending Reddit as a therapeutic virtual community and the need for implementing online resources as a part of a health care professional's repertoire to understand the level of support they can give their patients.

Abstract
BACKGROUND The COVID-19 pandemic spurred an increase in online information regarding disease spread and symptomatology. OBJECTIVE Our purpose is to systematically assess the quality and readability of articles resulting from frequently Google-searched COVID-19 terms in the United States. METHODS We used Google Trends to determine the 25 most commonly searched health-related phrases between February 29 and April 30, 2020. The first 30 search results for each term were collected, and articles were analyzed using the Quality Evaluation Scoring Tool (QUEST). Three raters scored each article in authorship, attribution, conflict of interest, currency, complementarity, and tone. A readability analysis was conducted. RESULTS Exactly 709 articles were screened, and 195 fulfilled inclusion criteria. The mean article score was 18.4 (SD 2.6) of 28, with 7% (14/189) scoring in the top quartile. National news outlets published the largest share (70/189, 36%) of articles. Peer-reviewed journals attained the highest average QUEST score compared to national/regional news outlets, national/state government sites, and global health organizations (all P<.05). The average reading level was 11.7 (SD 1.9, range 5.4-16.9). Only 3 (1.6%) articles were written at the recommended sixth grade level. CONCLUSIONS COVID-19-related articles are vastly varied in their attributes and levels of bias, and would benefit from revisions for increased readability.

Abstract
Chemotherapy is one of the most common forms of treatment for women with breast cancer. While chemotherapy is often effective, managing side effects can be challenging. Chemotherapy education is critical in assisting patients to manage side effects and to improve the treatment experience. However, materials are often not thoroughly assessed for readability and format which could be problematic for patients learning self-care while in treatment. We used a mixed-method design to illuminate chemotherapy teaching and focused on readability and format of education materials. We scored the materials using three readability assessments: (1) Flesch Reading Ease (FRE), (2) Flesch-Kincaid (F-K), and (3) a Simple Measure of Gobbledygook (SMOG). We evaluated the format of the materials using Suitability Assessment of Materials (SAM) guidelines. Lastly, we used thematic analysis to describe the experience of 37 women with breast cancer undergoing chemotherapy education. The mean readability of the materials ranged from "difficult" to "fairly difficult" based on the FRE scoring, and the material was written on a 9th- to 13th-grade reading level. Most of the materials scored as "adequate" using SAM guidelines but lacked incorporation of graphics or illustrations. The thematic analysis revealed three major findings: (1) finding control in learning, (2) receiving unexpected support, and (3) learning in unforeseen ways. Nurses need to supplement chemotherapy education materials with individualized teaching to ensure comprehension. Additionally, nurses and website developers may want to consider implementing culturally appropriate information and use videos to combat challenging readability.

Abstract
BACKGROUND Chemotherapy knowledge is linked to managing side effects, reducing exposure to potential infection, and adjusting lifestyle behaviors while going through treatment. However, no research exists regarding the influence of patients' personal attributes on chemotherapy knowledge. Aim The aim of this study was to describe the relationships of health literacy and demographics on chemotherapy knowledge among women with breast cancer undergoing treatment. METHOD We used a descriptive, exploratory design with convenience sampling of women with breast cancer receiving intravenous chemotherapy who completed one mandatory education session. Participants completed a demographic questionnaire and three instruments: 1) Rapid Estimate of Adult Literacy - Short Form (REALM-SF); 2) Shortened Test of Functional Health Literacy in Adults (S-TOFHLA); and 3) Leuven Questionnaire on Patient Knowledge of Chemotherapy (L-PaKC). We used univariate linear regression and ANOVA to identify how health literacy and demographics influenced chemotherapy knowledge. RESULTS The REALM-SF (p = .022) and S-TOFHLA (p = .023) scores were significantly associated with chemotherapy knowledge. Chemotherapy knowledge scores were affected by marital status (p = .018) and income (p < .001) where married women had significantly higher chemotherapy knowledge scores (M = 92.6, SD = 6.6) than women who were divorced (M = 83.3, SD = 16.7) with a knowledge score difference of -9.3 between the groups (p = .02). Comparisons showed significant differences of chemotherapy knowledge between women with differing income levels. CONCLUSIONS This study highlights the relevance of considering patients' health literacy and personal attributes such as marital status and income when teaching about chemotherapy.

Abstract
Background Mobile health (mHealth) apps are dramatically changing how patients and providers manage and monitor chronic health conditions, especially in the area of self-monitoring. African Americans have higher mortality rates from heart failure than other racial groups in the United States. Therefore, self-management of heart failure may improve health outcomes for African American patients. Objective The aim of the present study was to determine the feasibility of using an mHealth app, and explore the outcomes of quality of life, including self-care maintenance, management, and confidence, among African American patients managing their condition after discharge with a diagnosis of heart failure. Methods Prior to development of the app, we conducted qualitative interviews with 7 African American patients diagnosed with heart failure, 3 African American patients diagnosed with cardiovascular disease, and 6 health care providers (cardiologists, nurse practitioners, and a geriatrician) who worked with heart failure patients. In addition, we asked 6 hospital chaplains to provide positive spiritual messages for the patients, since spirituality is an important coping method for many African Americans. These formative data were then used for creating a prototype of the app, named Healthy Heart. Specifically, the Healthy Heart app incorporated the following evidence-based features to promote self-management: one-way messages, journaling (ie, weight and symptoms), graphical display of data, and customized feedback (ie, clinical decision support) based on daily or weekly weight. The educational messages about heart failure self-management were derived from the teaching materials provided to the patients diagnosed with heart failure, and included information on diet, sleep, stress, and medication adherence. The information was condensed and simplified to be appropriate for text messages and to meet health literacy standards. Other messages were derived from interviews conducted during the formative stage of app development, including interviews with African American chaplains. Usability testing was conducted over a series of meetings between nurses, social workers, and computer engineers. A pilot one-group pretest-posttest design was employed with participants using the mHealth app for 4 weeks. Descriptive statistics were computed for each of the demographic variables, overall and subscales for Health Related Quality of Life Scale 14 (HQOL14) and subscales for the Self-Care of Heart Failure Index (SCHFI) Version 6 using frequencies for categorical measures and means with standard deviations for continuous measures. Baseline and postintervention comparisons were computed using the Fisher exact test for overall health and paired t tests for HQOL14 and SCHFI questionnaire subscales. Results A total of 12 African American participants (7 men, 5 women; aged 51-69 years) diagnosed with heart failure were recruited for the study. There was no significant increase in quality of life (P=.15), but clinically relevant changes in self-care maintenance, management, and confidence were observed. Conclusions An mHealth app to assist with the self-management of heart failure is feasible in patients with low literacy, low health literacy, and limited smartphone experience. Based on the clinically relevant changes observed in this feasibility study of the Healthy Heart app, further research should explore effectiveness in this vulnerable population.

Abstract
PURPOSE Adherence to endocrine therapy for hormone positive breast cancer is a significant problem, especially in minority populations. Further, endocrine therapy reduces recurrence and thus mortality. However, little data are available on interventions to improve adherence. The authors conducted a systematic review to examine the impact of interventions, strategies, or approaches aimed to improve endocrine therapy adherence among women with breast cancer. A secondary aim was to determine if interventions had any cultural modifications. METHODS Two of the authors examined articles published between 2006 and 2017 from a wide variety of databases using Covidence systematic review platform. RESULTS In total, 16 eligible studies met criteria for review including 4 randomized controlled trials, 4 retrospective studies, and 8 with various observational designs. Eligible studies used a broad range of definitions for adherence and measured adherence by self-report, medical records, claims data, and combinations of these. All used 80% medication possession ratio as a standard for adherence. Patient information/education was the most frequent intervention strategy but did not demonstrate a significant effect except in one study. Significant results were noted when education was combined with communication strategies. CONCLUSIONS Researchers need a standard definition for adherence and a reliable measure that is feasible to use in a variety of studies. While education may be a necessary component of an intervention, when used alone, it is not a sufficient approach to change behavior.

Abstract
BACKGROUND Chemotherapy is commonly used in combination with other treatments for breast cancer. However, low adherence to chemotherapy is a growing concern, particularly among breast cancer patients. Side effects such as nausea and vomiting, fatigue, and arthralgia can contribute to reduced adherence. Other factors such as provider communication and limited insurance coverage can affect adherence. Studies have shown that as much as 28% of patients with breast cancer did not continue with their prescribed dose of chemotherapy. Research suggests that chemotherapy education materials can be critical to addressing problems with non-adherence, and may include written materials, verbal instruction, and multimedia programs. Despite this wide variety, the effectiveness and benefit of chemotherapy education hinges on the patients' health literacy. Breast cancer patients with low health literacy may be unclear about chemotherapy or face difficulty adhering to treatment if they do not understand the information provided to them. Thus, this scoping review summarizes the existing research on how health literacy principles are incorporated into breast cancer chemotherapy education materials. METHODS Using a combination of keywords (e.g. chemotherapy, education) and Medical subject headings (MeSH) terms (e.g., drug therapy, antineoplastic agents), we searched five databases (1977-2017): CINAHL, PubMed, PsycINFO, Cochrane Library, and Web of Science. RESULTS Eight of 4,624 articles met the inclusion criteria. Five articles incorporated health literacy principles (e.g., plain language, maintaining an active voice, using white space) into the development of written materials. Few articles used a theoretical framework to guide education material development (n = 3). Of the three articles that described pilot-testing of educational materials, two used post-tests only and one used a pre/post-test design. CONCLUSIONS Findings indicated that limited research exists regarding the use of health literacy principles in chemotherapy education materials. Much of the development of chemotherapy education is not grounded in theory and the application of health literacy principles is limited. Implementing health literacy principles may improve overall comprehension of education thereby increasing adherence.

Abstract
The Large Underground Xenon (LUX) experiment is a dual-phase xenon time-projection chamber operating at the Sanford Underground Research Facility (Lead, South Dakota). The LUX cryostat was filled for the first time in the underground laboratory in February 2013. We report results of the first WIMP search data set, taken during the period from April to August 2013, presenting the analysis of 85.3 live days of data with a fiducial volume of 118 kg. A profile-likelihood analysis technique shows our data to be consistent with the background-only hypothesis, allowing 90% confidence limits to be set on spin-independent WIMP-nucleon elastic scattering with a minimum upper limit on the cross section of 7.6 × 10(-46) cm(2) at a WIMP mass of 33 GeV/c(2). We find that the LUX data are in disagreement with low-mass WIMP signal interpretations of the results from several recent direct detection experiments.

Abstract
The quantitative consistency of nucleon transfer reactions as a probe of the occupancy of valence orbits in nuclei is tested. Neutron-adding, neutron-removal, and proton-adding transfer reactions were measured on the four stable even Ni isotopes, with particular attention to the cross section determinations. The data were analyzed consistently in terms of the distorted wave Born approximation to yield spectroscopic factors. Valence-orbit occupancies were extracted, utilizing the Macfarlane-French sum rules. The deduced occupancies are consistent with the changing number of valence neutrons, as are the vacancies for protons, both at the level of <5%. While there has been some debate regarding the true "observability" of spectroscopic factors, the present results indicate that empirically they yield self-consistent results.

Abstract
The possibility of observing neutrinoless double beta decay offers the opportunity of determining the effective neutrino mass if the nuclear matrix element were known. Theoretical calculations are uncertain, and measurements of the occupations of valence orbits by nucleons active in the decay can be important. The occupation of valence neutron orbits in the ground states of 76Ge (a candidate for such decay) and 76Se (the daughter nucleus) were determined by precisely measuring cross sections for both neutron-adding and removing transfer reactions. Our results indicate that the Fermi surface is much more diffuse than in theoretical calculations. We find that the populations of at least three orbits change significantly between these two ground states while in the calculations, the changes are confined primarily to one orbit.

Abstract
The difference in the energies of the lowest states corresponding to the two nodeless single-particle orbitals outside the Z=50 closed proton shell, h(11/2) and g(7/2), increases with neutron excess. We have measured the Sn(alpha,t) reaction for all seven stable even Sn isotopes and found that the spectroscopic factors are constant for these two states, confirming their characterization as single-particle states. The trend in energies is consistent with a decrease in the nuclear spin-orbit interaction. A similar trend, also suggesting a decreasing spin-orbit splitting, is seen in the energies of the neutron single-particle states outside the N=82 core, i(13/2) and h(9/2).

Abstract
The 21Na(p,gamma)22Mg reaction is expected to play an important role in the nucleosynthesis of 22Na in oxygen-neon novae. The decay of 22Na leads to the emission of a characteristic 1.275 MeV gamma-ray line. This report provides the first direct measurement of the rate of this reaction using a radioactive 21Na beam, and discusses its astrophysical implications. The energy of the important state was measured to be E(c.m.)=205.7+/-0.5 keV with a resonance strength omegagamma=1.03+/-0.16(stat)+/-0.14(sys) meV.

Abstract
Production of the radioisotope 18F in novae is severely constrained by the rate of the 18F(p,alpha)15O reaction. A resonance at E(c.m.)=330 keV may strongly enhance the 18F(p,alpha)15O reaction rate, but its strength has been very uncertain. We have determined the strength of this important resonance by measuring the 18F(p,alpha)15O cross section on and off resonance using a radioactive 18F beam at the ORNL Holifield Radioactive Ion Beam Facility. We find that its resonance strength is 1.48+/-0.46 eV, and that it dominates the 18F(p,alpha)15O reaction rate over a significant range of temperatures characteristic of ONeMg novae.

Abstract
Premenstrual syndrome is characterized by an array of somatic, cognitive, affective and behavioral disturbances that recur in cyclic fashion during the luteal phase of the menstrual cycle. The goal of management is to control symptoms well enough that the patient can function appropriately at all stages of the menstrual cycle. Both the patient and the physician must acknowledge that premenstrual syndrome is a complex reproductive disorder with a large number of possible manifestations; therefore, they must be willing to consider more than one strategy, and they must allow sufficient time to seek out successful therapeutic options. The patient must play an active role in all stages of management. Although no specific cure for premenstrual syndrome currently exists, most patients experience significant reduction of symptoms and improvement of quality of life when a rational individualized approach is used. Management may involve pharmacologic, nutritional and psychosocial interventions.
