Item A pilot survey of breast cancer survivors' reporting of palpitations to healthcare providers(Sage, 2024) Carpenter, Janet S.; Sheng, Ying; Snyder, Morgan; Fagan, Rileigh; Ekanayake, Vindhya; Elkins, Gary R.; School of NursingBackground: Breast cancer survivors (BCS) may experience cardiotoxicities from chemotherapy and oral endocrine therapy. Although a few studies have documented that palpitations are prevalent and associated with poorer outcomes, there is limited to no information on BCS' reporting of palpitations to healthcare providers. Objectives: To compare BCS who did and did not report their palpitations to a healthcare provider and describe how those who did report palpitations recalled their provider responding. Design: This was a cross-sectional, national, electronic, pilot survey of BCS enrolled in the Love Army of Women registry. Methods: Participants (n = 52 with palpitations) completed standardized and investigator-designed questionnaires. Data were analyzed using frequency and descriptive statistics, chi-square tests, and Mann-Whitney tests. Responses to one open-ended question were analyzed using frequency counts and standard content analysis. Results: Compared to BCS who reported palpitations to a provider (n = 34), BCS who did not report their palpitations (n = 18) were significantly more anxious (p = 0.002) and more likely to feel palpitations as an irregular heartbeat (70.6% versus 38.9%, p = 0.027). Among the 34 BCS who reported palpitations to a provider, 32 completed the open-ended question. Of these 32 BCS, a majority (n = 27, 84%) indicated their provider recommended cardiac testing and/or referral to a cardiologist. Most (n = 24) reported completing testing. Test results included diagnosis of a new arrhythmia or other cardiac abnormality (n = 11, 46%), receipt of a new prescription (n = 5, 21%), or normal results (n = 5, 21%). Five (16%) of the 32 BCS did not receive recommendations for testing or referral and felt their provider normalized or dismissed their symptoms. Conclusion: Palpitations are a salient topic for further research and clinical practice recommendations to address cardiac health in BCS.Item Anxiogenic CO2 Stimulus Elicits Exacerbated Hot Flash-like Responses in a Rat Menopause Model and Hot Flashes in Menopausal Women(Lippincott, Williams & Wilkins, 2016-11) Federici, Lauren M.; Roth, Sarah Dorsey; Krier, Connie; Fitz, Stephanie D.; Skaar, Todd C.; Shekhar, Anantha; Carpenter, Janet S.; Johnson, Philip L.; Anatomy and Cell Biology, School of MedicineObjective Since longitudinal studies determined that anxiety is a strong risk factor for hot flashes, we hypothesized that an anxiogenic stimulus that signals air hunger (hypercapnic, normoxic gas) would trigger an exacerbated hot flash-associated increase in tail skin temperature (TST) in a rat ovariectomy (OVEX) model of surgical menopause and hot flashes in symptomatic menopausal women. We also assessed TST responses in OVEX serotonin transporter (SERT)+/− rats that models a common polymorphism that is associated with increased climacteric symptoms in menopausal women and increases in anxiety traits. Methods OVEX and sham-OVEX rats (initial experiment) and wildtype and SERT+/− OVEX rats (subsequent experiment) were exposed to a 5 min infusion of 20%CO2 normoxic gas while measuring TST. Menopausal women were given brief 20% and 35%CO2 challenges, and hot flashes were self-reported and objectively verified. Results Compared to controls, OVEX rats had exacerbated increases in TST, and SERT+/− OVEX rats had prolonged TST increases following CO2. Most women reported mild/moderate hot flashes after CO2 challenges, and the hot flash severity to CO2 was positively correlated with daily hot flash frequency. Conclusions The studies demonstrate that this anxiogenic stimulus is capable of inducing cutaneous vasomotor responses in OVEX rats, and eliciting hot flashes in menopausal women. In rats, the severity of the response was mediated by loss of ovarian function and increased anxiety traits (SERT+/−), and, in women, by daily hot flash frequency. These findings may provide insights into anxiety related triggers and genetic risk factors for hot flashes in thermoneutral environments.Item An Arts-Based Educational Exhibit on Menopausal Hot Flashes(Wolters Kluwer, 2019) Carpenter, Janet S.; Kesling, Mark; Schmidt, Karen K.; School of NursingObjective: The aim of this study was to describe the development process, science, and symbolism of an arts-based educational exhibit designed to address myths, misinformation, negative imagery, and use of unproven treatments related to menopausal hot flashes. Methods: The development process included iterative and informal feedback from a variety of individuals, a partnership with an experienced exhibit designer, and collaborations between artists and scientists. Results: The resulting exhibit creates an environment where the public is immersed in accurate information about hot flashes. Although based on an iterative process, the resulting exhibit content reflects an estimated 500+ scientific studies, including those referenced in The North American Menopause Society position statements on hormone and nonhormone management of hot flashes. The seven main exhibit pieces convey scientific information and symbolize various aspects of women's experiences. Conclusions: This innovative exhibit has high potential to be a disruptive innovation to address the preponderance of myths, misinformation, and negative imagery surrounding menopausal hot flashes and potentially decrease the use of unproven therapies.Item Associations Between Dysmenorrhea Symptom-Based Phenotypes and Vaginal Microbiome: A Pilot Study(Wolters Kluwer, 2021) Chen, Chen X.; Carpenter, Janet S.; Gao, Xiang; Toh, Evelyn; Dong, Qunfeng; Nelson, David E.; Mitchell, Caroline; Fortenberry, J. DennisBACKGROUND: Dysmenorrhea is highly prevalent; it places women at risk for other chronic pain conditions. There is a high degree of individual variability in menstrual pain severity, the number of painful sites, and co-occurring gastrointestinal symptoms. Distinct dysmenorrhea symptom-based phenotypes were previously identified, but the biological underpinnings of these phenotypes are less known. One underexplored contributor is the vaginal microbiome. The vaginal microbiota differs significantly among reproductive-age women and may modulate as well as amplify reproductive tract inflammation, which may contribute to dysmenorrhea symptoms. OBJECTIVES: The objective of this study was to examine associations between dysmenorrhea symptom-based phenotypes and vaginal microbiome compositions on- and off-menses. METHODS: We conducted a prospective, longitudinal, pilot study of 20 women (aged 15-24 years) grouped into three dysmenorrhea symptom-based phenotypes: "mild localized pain," "severe localized pain," and "severe multiple pain and gastrointestinal symptoms." Over one menstrual cycle, participants provided vaginal swabs when they were on- and off-menses. We assayed the vaginal microbiome using 16S rRNA gene sequencing. Permutational multivariate analysis of variance tests were used to compare microbiome compositions across phenotypes, with heat maps generated to visualize the relative abundance of bacterial taxa. RESULTS: The vaginal microbiome compositions (n = 40) were different across the three phenotypes. After separating the on-menses (n = 20) and off-menses (n = 20) specimens, the statistically significant difference was seen on-menses, but not off-menses. Compared to the "mild localized pain" phenotype, participants in the "multiple severe symptoms" phenotype had a lower lactobacilli level and a higher abundance of Prevotella, Atopobium, and Gardnerella when on-menses. We also observed trends of differences across phenotypes in vaginal microbiome change from off- to on-menses. DISCUSSION: The study provides proof-of-concept data to support larger studies on associations between dysmenorrhea symptom-based phenotypes and vaginal microbiome that might lead to new intervention targets and/or biomarkers for dysmenorrhea. This line of research has the potential to inform precision dysmenorrhea treatment that can improve women's quality of life.Item Big Data and Dysmenorrhea: What Questions Do Women and Men Ask About Menstrual Pain?(Liebert, 2018-10) Chen, Chen X.; Groves, Doyle; Miller, Wendy R.; Carpenter, Janet S.; School of NursingBackground: Menstrual pain is highly prevalent among women of reproductive age. As the general public increasingly obtains health information online, Big Data from online platforms provide novel sources to understand the public's perspectives and information needs about menstrual pain. The study's purpose was to describe salient queries about dysmenorrhea using Big Data from a question and answer platform. Materials and Methods: We performed text-mining of 1.9 billion queries from ChaCha, a United States-based question and answer platform. Dysmenorrhea-related queries were identified by using keyword searching. Each relevant query was split into token words (i.e., meaningful words or phrases) and stop words (i.e., not meaningful functional words). Word Adjacency Graph (WAG) modeling was used to detect clusters of queries and visualize the range of dysmenorrhea-related topics. We constructed two WAG models respectively from queries by women of reproductive age and bymen. Salient themes were identified through inspecting clusters of WAG models. Results: We identified two subsets of queries: Subset 1 contained 507,327 queries from women aged 13–50 years. Subset 2 contained 113,888 queries from men aged 13 or above. WAG modeling revealed topic clusters for each subset. Between female and male subsets, topic clusters overlapped on dysmenorrhea symptoms and management. Among female queries, there were distinctive topics on approaching menstrual pain at school and menstrual pain-related conditions; while among male queries, there was a distinctive cluster of queries on menstrual pain from male's perspectives. Conclusions: Big Data mining of the ChaCha® question and answer service revealed a series of information needs among women and men on menstrual pain. Findings may be useful in structuring the content and informing the delivery platform for educational interventions.Item Big Data and Dysmenorrhea: What Questions Do Women and Men Ask About Menstrual Pain?(Mary Ann Liebert, 2018-10) Chen, Chen X.; Groves, Doyle; Miller, Wendy R.; Carpenter, Janet S.; School of NursingBACKGROUND: Menstrual pain is highly prevalent among women of reproductive age.

While hot flashes occur at random and are difficult to study, there is a method of testing panic attacks. A Carbon Dioxide (CO2) Challenge is a validated method that has been used to induce panic attacks in a laboratory setting. The aim of this study is to test whether a CO2 Challenge using inhalations of 20% and 35% CO2 can provoke a hot flash in menopausal women. We hypothesize that women who have many hot flashes each day (4+) will have a hot flash when exposed to the increased concentration of CO2 using this challenge. Six healthy women attended a study session lasting ninety minutes. In this placebo controlled, cross-over study, women inhale room air, 20% CO2 for 40 seconds, rest for 15 minutes, and 35% CO2 using a double-breath vital capacity inhalation. Anxiety was measured on a numeric rating scale (NRS) and a State Trait Anxiety Inventory (STAI). Most participants have reported a hot flash within minutes of the CO2Challenge. There have been no significant changes in anxiety during the study. Findings provide evidence of the proposed link between hot flashes and panic.Item Career Decision-Making in Diverse Nursing Students: Choosing a Career in Nursing(2024-04) McCord, Geoffrey Aaron; Otte, Julie L.; Ellis, Rebecca; Carpenter, Janet S.; Schall, Carly E.The nursing profession lacks diversity that reflects the population it serves. The population of LPN/LVN and ADN students are known to be more diverse than BSN students. Little is known about the differences between the students in the three levels of nursing programs (LPN/LVN, ADN, BSN), including reasons for choosing nursing, and barriers and facilitators. The McCord Nursing Career and Educational Decision Pathway Conceptual Framework guided this study. A quantitative survey was conducted of current nursing students in the US. The study asked demographic information as well as motivating factors, barriers, and facilitators for choosing nursing and their program type (LPN/LVN, ADN, BSN). Responses from 741 nursing students in LPN/LVN, ADN, and BSN programs from 26 states. The study found significant differences between the students in the three educational pathways. There are significant racial and financial differences and differences in reasons for choosing nursing, educational background, commitments outside of school, and barriers to goal achievement. LPN/LVN students were more likely to be Black and ADN students were more likely to be Hispanic. There was greater racial diversity in the LPN/LVN and ADN groups. LPN/LVN students are more likely to identify nursing as their first career choice and most want to be an RN. LPN/LVN and ADN students were more worried than BSN students about their family commitments, financial obligations, and their ability to succeed in nursing school. Some of the lack of diversity in BSN programs reflects the challenges that racial minorities face in goal achievement. Identified barriers include outside financial commitments, the cost vii of nursing programs, and the length of time of the programs. The goal to increase diversity in nursing should consider the entire population of those who want to become nurses.Item Communication Between Registered Nurses and Family Members of Intensive Care Unit Patients(AACN, 2022-12-01) Dees, Mandy L.; Carpenter, Janet S.; Hoffman-Longtin, Krista; School of NursingBackground Effective communication between intensive care unit patients and their families and nurses promotes relationship-centered care and improves nurses’ ability to meet patient and family needs. However, communication with these patients is challenging because of their critical illness. Families often become surrogate decision makers for adult intensive care unit patients. Objective To systematically assess available evidence on communication between adult intensive care unit patients and their families and nurses as the initial step in developing nursing strategies to strengthen communication skills. Methods In this integrative review, the method of Whittemore and Knafl was used to synthesize findings from qualitative and quantitative (descriptive and experimental) research. Results The review revealed a variety of research designs, measurement tools, and types of interventions. The qualitative findings suggest that nurses can strengthen relationship-centered care by regularly updating patients’ families and providing information that can assist with decision-making. The quantitative findings suggest that nurses should be mindful of family members’ needs for assurance, comfort, and support. Providing information on patient status can help alleviate family concerns. Conclusions Improved communication between patients and families and intensive care unit nurses is essential to strengthen relationship-centered care. Additional research is needed to better understand the communication needs of adult patients and their families in the intensive care unit.Item Confirmatory factor analysis of the Insomnia Severity Index (ISI) and invariance across race: a pooled analysis of MsFLASH data(Wolters Kluwer, 2019-08-01) Otte, Julie L.; Bakoyannis, Giorgos; Rand, Kevin L.; Ensrud, Kristine E.; Guthrie, Katherine A.; Joffe, Hadine; McCurry, Susan M.; Newton, Kathrine M.; Carpenter, Janet S.; School of NursingObjective: Women's sleep at menopause is widely reported to be problematic. The Insomnia Severity Index is a commonly used tool for quantifying sleep problems in clinical and research settings, but psychometric properties in menopausal women have not been reported. Our study aim was to examine the factor structure of the Insomnia Severity Index in a large and diverse sample of midlife women with hot flashes. Methods: Baseline data were from 899 women enrolled in one of the three clinical trials using similar entry criteria conducted by the Menopause Strategies Finding Lasting Answers to Symptoms and Health (MsFLASH) research network. We conducted confirmatory factor analyses for the total sample and within strata defined by race/ethnicity (Black and White women). Results: The Insomnia Severity Index had two factors in the total sample. The 2-factor structure was consistent across Black and White women, with the exception of one item “Difficulty falling asleep”. Conclusions: The Insomnia Severity Index in midlife women with hot flashes is composed of two factors that capture dimensions of the insomnia severity and daytime impact. The instrument is a psychometrically sound scale appropriate for use in research and clinical practice to capture the severity and daytime impact of insomnia symptoms in diverse samples of midlife women with hot flashes. An abbreviated screening of two items could be considered to determine if further evaluation is needed of sleep complaints.
