Exploring the Experiential Journey of Women with PCOS Across the Lifespan: A Qualitative Inquiry.

Introduction: Peri-postmenopausal women with the chronic condition polycystic ovary syndrome (PCOS) remain at cardiometabolic risk and/or subsist with established comorbidity while continuing to manage persistent PCOS signs and symptoms, such as hirsutism. Thus, PCOS transcends the reproductive years, yet there is sparse scientific literature on the peri-postmenopausal years of women with PCOS. Purpose: To explore how peri-postmenopausal women's perceptions about PCOS have changed over the lifespan since their PCOS diagnosis. Methods: A cross-sectional survey with one qualitative question was conducted via Research Electronic Data Capture (REDCap) among women with PCOS aged ≥43 years, who were all recruited from PCOS-specific Facebook pages. Of the 107 women completing the survey, 72 substantively answered the qualitative question. The qualitative responses were analyzed using the steps of reflexive thematic analysis. Themes were interpreted and discussed through the lens of the bioecological conceptual model. Results: Respondents were 47.6 (±4.1) years of age, primarily White (87.5%), employed full time (65.3%), and married (75%) with children (68%). Four overall themes were identified: 1) dismissal 2) information desert, 3) PCOS experience over the lifespan, and 4) mindset. Conclusion: The study findings illustrated the unique healthcare needs among peri-postmenopausal women with PCOS. Further research is needed to further explore their healthcare concerns and psychosocial needs followed by studies that develop and assess interventions that promote symptom and adaptive coping strategies across their lifespan.

Exploratory factor and confirmatory analyses of the polycystic ovary syndrome health-related quality of life questionnaire (PCOSQ-50).

BACKGROUND: A condition-specific instrument is necessary to measure the health-related quality of life among those with polycystic ovary syndrome (PCOS), the most common chronic endocrinopathy among women. The first instrument was developed in 1988, followed by several revisions. However, further recommendations from all versions include additional application and measurement among different cultural populations of women with PCOS and psychometric testing based on use among larger samples of women with PCOS. Thus, the purpose of this study was to explore the factor structure of the Polycystic Ovary Syndrome Questionnaire (PCOSQ-50) using an international cross-sectional survey data from women with PCOS aged 18-42 years. METHODS: Using data from the largest known international cross-sectional study of women with PCOS aged 18-42 years (n = 935) to date, exploratory factor and confirmatory analyses were conducted for the PCOSQ-50, followed by factor labeling using a thematic analysis approach. RESULTS: Respondents were 31.0 ± 5.8 years of age, mostly White (72%), well-educated (56% had a college degree), married (69%), and employed full-time (65%). Three-quarters (74%) of the sample had one or more chronic conditions in addition to PCOS. Approximately 20% of the respondents originated from countries such as the United Kingdom, Australia, South Africa, etc. The PCOSQ-50 demonstrated good reliability but may be best described using a 7-factor model. The 7-factor model revealed goodness-of-fit. Thematic analysis suggested the following labels of those seven factors: hirsutism, fertility, isolation/trepidation, sexual function, self-esteem, emotional, and obesity. CONCLUSION: More research is needed to adapt the current PCOSQ-50, as well as to create an age-appropriate PCOS-specific HRQoL instrument for peri-postmenopausal women with PCOS.

Next generation nurse scientists: A systems approach to engaging undergraduate students in research.

BACKGROUND: Nursing Doctor of Philosophy program enrollment has declined. Undergraduate nursing student (UGS) research engagement is associated with future graduate education, an essential element for building the nursing faculty pipeline. PURPOSE: (a) To describe the infrastructure and culture-enhancing resources and strategies associated with building UGS research engagement and (b) to evaluate UGS research engagement. METHODS: Guided by a socioecological systems model university and college documents, databases, and college of nursing survey results were used to identify approaches to, and outcomes of, engaging UGS in research. Descriptive statistics were calculated to illustrate 5-year UGS research engagement trends. FINDINGS: Resources and strategies included grant funding, research assistant funding, student research showcases, and faculty mentorship. UGS research 5-year engagement trends included (a) a 75% increase in the number of students mentored, (b) a 30% rise in funded research proposals, and (c) a 54% increase in paid research assistantships. DISCUSSION: Purposefully using existing resources, growing the college of nursing infrastructure, and cultivating a culture recognizing faculty contributions were approaches associated with increased UGS research engagement.

Perceptions of COVID-19 and the Use of Health Information Technology Among People Who Are Uninsured: Multimethod Survey Study.

BACKGROUND: As of May 2023, the novel SARS-CoV-2 has claimed nearly 7 million lives globally and >1.1 million lives in the United States. Low-income populations are often disproportionately affected by risk factors such as lifestyle, employment, and limited health literacy. These populations may lack the knowledge of appropriate infection precautions or have reduced access to care during illness, particularly in countries without universal health care. OBJECTIVE: We aimed to explore the perceptions and experiences of COVID-19, including symptoms and risk factors among uninsured individuals seeking care at a free medical clinic, and to obtain respondents' perceptions of and suggestions for adapting a mobile health (mHealth) app to an uninsured population known to have low health literacy. METHODS: We conducted a prospective multimethod survey study with a convenience sample of uninsured adults seeking care at 3 free clinics in the United States. Respondents were questioned about their risk for and awareness of COVID-19 symptoms, COVID-19 testing, current technology use, and the use of technology to facilitate their health regarding COVID-19. Data were analyzed using descriptive statistics (eg, frequencies and mean differences). In addition, a small subset of respondents from one of the clinics (n=10) participated in interviews to provide feedback about the design of a COVID-19 web-based smartphone (mHealth) app. RESULTS: The survey respondents (N=240) were 53.8% (n=129) female, were primarily White (n=113, 47.1%), and had a mean age of 50.0 (SD 11.67; range 19-72) years. Most respondents (162/222, 73%) did not think that they were at risk for COVID-19. Although respondents reported only moderate confidence in their knowledge of the short- and long-term symptoms of COVID-19, their knowledge of the symptoms aligned well with reports published by the Centers for Disease Control and Prevention of the most common acute (590/610, 96.7%) and long-term (217/271, 80.1%) symptoms. Most respondents (159/224, 71%) reported an interest in using the mHealth app to gain additional information regarding COVID-19 and available community resources. Respondents who were interviewed provided suggestions to improve the mHealth app but had overall positive perceptions about the potential usefulness and usability of the app. CONCLUSIONS: It was encouraging that the knowledge of COVID-19 symptoms aligned well with the reports published by the Centers for Disease Control and Prevention and that respondents were enthusiastic about using an mHealth app to monitor symptoms. However, it was concerning that most respondents did not think they were at a risk of contracting COVID-19.

Barriers and Facilitators of Diet, Physical Activity Levels, and Sleep Among Nursing Undergraduates and Early-Career Nurses: A Qualitative Descriptive Study.

PURPOSE: Mechanisms leading to burnout, associated with high turnover in nursing, may start as early as in nursing school. Given health habits (e.g., diet, physical activity, and sleep) can exacerbate or lessen the impact of burnout, this study examined current barriers and facilitators to healthy diet, physical activity levels, and sleep among nursing undergraduates (UGs) and early-career nurses (ECNs). RESEARCH DESIGN: Qualitative descriptive study. SAMPLE: 25 nursing UGs and 25 ECNs (within 3 years of graduation) from a Southeastern college of nursing. DATA COLLECTION AND ANALYSIS: After development of theory-informed interview guides, participants conducted interviews either in-person or by phone, which were audio-recorded and transcribed. Braun and Clarke's six-step thematic analysis was used to analyze the transcripts. RESULTS: All but one (aged 54) UG was in their early 20s and ECNs were in their early to mid-20s. Most participants were white, females. Time and stress were the strongest barriers among UGs and ECNs for adherence to healthy diet, physical activity, although stress did act as a facilitator for physical activity in a subset of both UGs and ECNs. Shiftwork was a common barrier to healthy behaviors among ECNs. CONCLUSION: The fact that the more common and stronger barriers to healthier behaviors among UGs and ECNs were the same give credence to the idea that processes associated with burnout begin during or before nursing education and are persistent.

Hepatitis B immunity among undergraduate nursing students: A brief report.

BACKGROUND: Health sciences students who report low/equivocal hepatitis B titers may be required to repeat the immunization series, even though the result may not indicate non-immunity. METHOD: To describe hepatitis B immunity patterns, this retrospective, descriptive study utilized de-identified vaccination records and anti-HBs titers of three cohorts of sophomore nursing students entering clinical rotations in 2018-2019. RESULTS: Only 33% of students had initial anti-HBs quantitative serum titer ≥10 mIU/ml, demonstrating immunity. After students with low/equivocal titers (n = 191, 64%) were re-immunized per institution protocol, only 2% (n = 7) were identified as non-responders. Cumulative costs incurred by students for revaccination and repeat titer exceeded $20,000, with a process time of up to 8 months. CONCLUSION: While rates of exposure to hepatitis B in acute care settings have steadily declined in the United States, students who go on to practice in community and public health settings have increased risk of exposure. Following best practices in demonstrating hepatitis B immunity, which include a single challenge dose followed by titer 4 weeks later, would decrease per student costs, wait time, and administrative burden associated with documentation and student counseling.

A systematic approach to developing NP-led student health services clinic on a regional university campus.

BACKGROUND: Universities are communities with specific health care needs, and rural campuses often do not have access to student health services (SHS). PROBLEM: Lack of basic services can increase health risks for students and the greater community. METHODS: A theory-informed quality improvement project utilizing an organizational assessment, study survey, and proof-of-concept intervention designed to demonstrate feasibility and acceptability of a SHS clinic. INTERVENTION: An NP-directed influenza immunization clinic was conducted on a small rural college campus in southeastern United States. RESULTS: Seventy-eight students received influenza vaccinations, demonstrating to local stakeholders the feasibility and acceptability of SHS for primary preventative services. Ninety-seven percent of these students expressed a high likelihood that they would obtain the vaccine again. CONCLUSIONS: Results of this study can be used as an exemplar to guide health care initiatives focused on college students in rural communities.

Foods and Beverages Available to Nurses in Hospital Cafeterias, Vending Machines, and Gift Shops.

PURPOSE: Hospitals are important workplaces for nurses with many perceived barriers to healthy eating, but objective assessments are lacking. This study evaluated the healthfulness of hospital consumer food environments. DESIGN: Cross-sectional observational; Setting: South Carolina; Subjects: Cafeterias, vending machines (VM), and gift shops (GS) in hospitals of varying size, urbanization, and region. MEASURES: Using the Hospital Nutrition Environment Scan (HNES), primary outcomes of interest included availability, access, prices, and location of healthy foods in relation to nursing units. ANALYSIS: Descriptive and inferential statistics by independent samples t-test, ANOVA, Mann-Whitney U, χ2, or Fisher's exact test as appropriate. RESULTS: Thirty-one hospitals were observed from December 2019 to February 2020. Average composite HNES score (n = 28) was 46.3 ± 14.9 (-45 to 173 range), indicating sub-optimal food environments. Cafeterias (n = 31) scored an average of 30.9 ± 10.5 (-33 to 86 range). Average VM (n = 31) and GS (n = 28) scores were 11.6 ± 6.0 (-6 to 55 range) and 2.9 ± 4.0 (-6 to 32 range), respectively. Small hospitals (≤100 beds) had lower average cafeteria score (22.4 ± 10.3) than extra-large hospitals (≥500 beds; 42 ± 5.2, P < .01). Small hospitals also had lower composite HNES scores (34.4 ± 17.1) compared to extra-large hospitals (61.0 ± 14.4, P = .02). Data regarding availability, access, prices, and location were also reported. CONCLUSION: Due to abundant availability of unhealthy foods and beverages, hospital consumer food environments scored low on observations using the HNES, highlighting the opportunity to improve the healthfulness of facility offerings.

Experiences of African Americans Living With Sickle Cell Disease.

INTRODUCTION: About 100,000 individuals in the United States live with sickle cell disease (SCD). Palliative care (PC) can improve symptom management for these individuals. The purpose of the study was to explore (a) the experiences of people living with SCD, and (b) their knowledge and perceptions of PC. METHOD: Using a qualitative, descriptive design, adults with SCD were recruited from a foundation in the southeastern United States. Data included social and SCD-related demographics and audio-recorded, semi-structured focus groups. Analysis took a thematic analysis approach. RESULTS: Participants: There were 16 African Americans who participated in the study, 75% of whom were females, and aged 22 to 71 years. Five themes were identified: unique and unpredictable impact of SCD on daily life, the changing experience of SCD over time, stigmatization/marginalization in health care interactions, perceptions of support in managing SCD symptoms/crises, and PC: "What is it?" DISCUSSION: Participants lacked PC knowledge. PC should be offered to individuals with SCD as part of comprehensive SCD management.

"I don't think I have a chance to get it": International university student HPV knowledge and preventive behaviors.

Objective: Half of new human papilloma virus ( (HPV)) infections occur between the ages of 15 and 24. As preventive measures are underutilized globally; international university students are at particular risk for HPV infection and sequelae. The study aim was to explore HPV knowledge and preventive behaviors in this population. Participants: Eighty-one undergraduate and graduate international university students (49 females, 32 males) at a southeastern university. Methods: Exploratory sequential mixed methods guided by the Health Belief Model. Results: Integrated qualitative/quantitative data revealed four themes mapped to relevant HBM constructs: Perceived susceptibility to HPV; Perceived benefits/Perceived barriers to HPV prevention; Cues to Action; and Likelihood of Engaging in Health-Promoting Behavior. Over half believed they were not at risk for HPV/sequelae. Only a quarter had received HPV vaccination. Conclusions: International university students represent an important catch-up population for HPV screening/vaccination. Results can be used to design and tailor interventions for this vulnerable population.

The impact of exercise perceptions and depressive symptoms on polycystic ovary syndrome-specific health-related quality of life.

BACKGROUND: Studies indicate that women with polycystic ovary syndrome have high depressive symptom scores and more perceived barriers than benefits to exercise, factors that may affect health-related quality-of-life. The purpose of this cross-sectional study was to explore the impact of perceived exercise benefits and barriers, exercise outcome expectations, and depressive symptoms on polycystic ovary syndrome-specific health-related quality-of-life. METHODS: A survey link was posted on polycystic ovary syndrome Facebook groups. Women with polycystic ovary syndrome (n = 935) answered questionnaires about demographics, polycystic ovary syndrome-specific health-related quality-of-life, exercise benefits and barriers, exercise outcome expectations, and depressive symptoms. Data were collected using Qualtrics, transferred to SPSS, and statistically analyzed using regression analyses. Mean responses were reported for the questionnaires, with exercise benefits and barriers means divided for a ratio. RESULTS: Respondents were 32 ± 10.6 years of age, mostly White (72%), and employed full-time (65%). The total mean scores were health-related quality-of-life, 2.7 ± 0.1; exercise outcome expectation, 2.4 ± 0.8; and depressive symptoms, 12.4 ± 5.8. The benefit/barrier ratio was 0.9. HRQoL increased 0.32 points for every additional perceived exercise benefit and 0.61 points for every additional exercise outcome expectation (EOE). HRQoL was reduced by 1.19 points for every additional perceived exercise barrier and 2.82 points for every additional one-point increase of the depressive symptoms score. CONCLUSIONS: Respondents reported low health-related quality-of-life, greater exercise barriers than benefits, neutral exercise outcome expectations, and high depressive symptoms. These results suggest that promoting exercise benefits, overcoming exercise barriers, and addressing management of depressive symptoms are important foci of future efforts to improve health-related quality-of-life among women with polycystic ovary syndrome.

Resistance Training as Therapeutic Management in Women with PCOS: What is the Evidence?

Polycystic ovary syndrome (PCOS), the most common chronic endocrinopathy and the leading cause of infertility in women, has significant clinical consequences, including cardiovascular, endocrinological, oncological, and psychological co-morbidities. Endocrine Society Clinical Practice Guidelines on the Diagnosis and Treatment of PCOS recommend exercise and physical activity as first-line treatment to combat chronic disease risk. However, details about what type of exercise are not provided. Given the known beneficial effects of resistance training on the management of other chronic diseases, the purpose of this scoping review was to evaluate the scientific evidence about the physical and psychosocial effects of resistance training among women with PCOS. Studies were identified through a systematic search of PubMed, SPORTDiscus, and CINAHL databases. Peer-reviewed research studies published between January 2011 and January 2021 that evaluated a resistance training intervention for premenopausal women with PCOS were included. Studies that offered multi-component programs were excluded. Nine articles met the inclusion criteria of which seven were sub-studies of one larger clinical trial. One article reported findings from a small randomized controlled trial and the last article reported feasibility study findings. Each intervention yielded positive results across a wide range of outcome variables; however, the studies had small sample sizes and assessed different outcome variables. Evidence regarding the effects of resistance training on health outcomes for women with PCOS is positive but preliminary. Adequately powered clinical trials are required to confirm health benefits, answer research questions as to therapeutic dose, and discover behavioral strategies to promote resistance training for therapeutic management.

"I FELT THE CONNECTION": A QUALITATIVE EXPLORATION OF STANDARDIZED PATIENTS' EXPERIENCES IN A DELIVERING BAD NEWS SCENARIO.

BACKGROUND: Little research has examined standardized patient experiences in stressful simulation scenarios. METHODS: Qualitative, secondary data analysis. RESULTS: Emergent themes included: "Those kinds of things are important": The incorporation of personal experiences enhances communication accommodation experiential learning; "She was trying to buffer the bad news": How SPs recognize and address problematic divergent behaviors; and "The emotions come up": Interactions with excellent communication accommodation behaviors can lead to SP emotional and physical distress. CONCLUSION: Standardized patient expertise enhances scenario realism and communication skills evaluation. To minimize distress, simulation educators should tailor safety measures specifically for the individual standardized patient and the scenario.

Free Food at Work: A Concept Analysis.

BACKGROUND: Employees who spend substantial amounts of time in a workplace away from home are likely to acquire and consume food during work hours. Reportedly, free food at work is a common occurrence in various workplace settings such as business offices and hospitals. Little is known about the nutritional quality, prevalence, or health impact of free food at work. Furthermore, free food at work as a theoretical concept has not been previously analyzed or defined, but it is necessary to differentiate free food from other food sources in the workplace. METHODS: A concept analysis of free food at work was conducted using the 8-step Walker and Avant framework. A literature review in June and July 2020 provided the basis to delineate the concept and identify its defining attributes including antecedents, consequences, and empirical referents. FINDINGS: Free food at work is defined as food that is available for consumption in the workplace at no financial cost to employees. Critical attributes of free food at work include nutritional value, quantity, frequency, and location within the workplace. Antecedents are sources and reasons for free food provision. Consequences include influence on consumption, behaviors, attitudes, emotions, and health outcomes. Additional measurable aspects of the concept and implications are discussed. CONCLUSION/APPLICATION TO PROFESSIONAL PRACTICE: The concept of free food at work was analyzed; defining attributes and empirical referents were discussed and presented in a conceptual model to encourage further study and theory development. Identifying the health impact of free food at work is an issue requiring consideration for workplace health-promoting programs.

Development of the Prostate Cancer Treatment Decision Framework: A Context-Specific Expansion of the Risk-as-Feelings Hypothesis.

BACKGROUND: Over the past 2 decades, numerous decision-making interventions have been developed to guide the prostate cancer (PrCA) treatment choices of patients and families. These interventions are often supported by economic decision frameworks, which do not account for the role of emotions in treatment decisions. In some instances, emotion-driven decisions can override an individual's cognitive evaluation of a decision, leading to unfavorable outcomes such as decision regret. OBJECTIVES: To produce a Prostate Cancer Treatment Decision Framework based on the Risk-as-Feelings Hypothesis. METHODS: The authors reviewed seminal research in emotion and decision-making in an effort to create a context-specific decision framework. RESULTS: Five variables, not germane to the Risk-as-Feelings Hypothesis, play prominent roles in PrCA decision-making including age, spirituality, family support, healthcare provider communication, and perception of treatment outcomes. While family support only affects decision outcomes by influencing emotion and cognitive evaluation of a PrCA decision, age, spirituality, and healthcare provider communication can have direct effects on an individual's perception of treatment outcomes. CONCLUSIONS: The Prostate Cancer Treatment Decision Framework combines new variables with older models to explain the PrCA treatment decision-making process and elucidate relationships affecting treatment outcomes and survivors' perceptions of these outcomes. The core premise of this model can be applied to other high-risk health decisions. IMPLICATIONS FOR PRACTICE: Healthcare providers have the greatest influence on PrCA treatment decision-making. Using a shared decision-making approach, providers should take into account a patient's personal characteristics and values, in addition to clinical presentation, to help patients with treatment decisions.

The Experience of Chemotherapy Teaching and Readability of Chemotherapy Educational Materials for Women with Breast Cancer.

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.

A Patient-Centered Asthma Management Communication Intervention for Rural Latino Children: Protocol for a Waiting-List Randomized Controlled Trial.

BACKGROUND: Rural Latino children with asthma suffer high rates of uncontrolled asthma symptoms, emergency department visits, and repeat hospitalizations. This vulnerable population must negotiate micro- and macrolevel challenges that impact asthma management, including language barriers, primary care access, parental time off from work, insurance coverage, distance from specialty sites, and documentation status. There are few proven interventions that address asthma management embedded within this unique context. OBJECTIVE: Using a bio-ecological approach, we will determine the feasibility of a patient-centered collaborative program between rural Latino children with asthma and their families, school-based nursing programs, and primary care providers, facilitated by the use of a smartphone-based mobile app with a Spanish-language interface. We hypothesize that improving communication through a collaborative, patient-centered intervention will improve asthma management, empower the patient and family, decrease outcome disparities, and decrease direct and indirect costs. METHODS: The specific aims of this study include the following: (1) Aim 1: produce and validate a Spanish translation of an existing asthma management app and evaluate its usability with Latino parents of children with asthma, (2) Aim 2: develop and evaluate a triadic, patient-centered asthma intervention preliminary protocol, facilitated by the bilingual mobile app validated in Aim 1, and (3) Aim 3: investigate the feasibility of the patient-centered asthma intervention from Aim 2 using a waiting-list randomized controlled trial (RCT) to investigate the effects of the intervention on school days missed and medication adherence. RESULTS: Mobile app translation, initial usability testing, and app software refinement were completed in 2019. Analysis is in progress. Preliminary protocol testing is underway; we anticipate that the waiting-list RCT, using the refined protocol developed in Aim 2, will commence in fall 2020. CONCLUSIONS: Tailored, technology-based solutions have the potential to successfully address issues affecting asthma management, including communication barriers, accessibility issues, medication adherence, and suboptimal technological interventions. TRIAL REGISTRATION: ClinicalTrials.gov NCT04633018; https://www.clinicaltrials.gov/ct2/show/NCT04633018. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/18977.

Dithered depth imaging.

Single-photon lidar (SPL) is a promising technology for depth measurement at long range or from weak reflectors because of the sensitivity to extremely low light levels. However, constraints on the timing resolution of existing arrays of single-photon avalanche diode (SPAD) detectors limit the precision of resulting depth estimates. In this work, we describe an implementation of subtractively-dithered SPL that can recover high-resolution depth estimates despite the coarse resolution of the detector. Subtractively-dithered measurement is achieved by adding programmable delays into the photon timing circuitry that introduce relative time shifts between the illumination and detection that are shorter than the time bin duration. Careful modeling of the temporal instrument response function leads to an estimator that outperforms the sample mean and results in depth estimates with up to 13 times lower root mean-squared error than if dither were not used. The simple implementation and estimation suggest that globally dithered SPAD arrays could be used for high spatial- and temporal-resolution depth sensing.

Seeing around corners with edge-resolved transient imaging.

Non-line-of-sight (NLOS) imaging is a rapidly growing field seeking to form images of objects outside the field of view, with potential applications in autonomous navigation, reconnaissance, and even medical imaging. The critical challenge of NLOS imaging is that diffuse reflections scatter light in all directions, resulting in weak signals and a loss of directional information. To address this problem, we propose a method for seeing around corners that derives angular resolution from vertical edges and longitudinal resolution from the temporal response to a pulsed light source. We introduce an acquisition strategy, scene response model, and reconstruction algorithm that enable the formation of 2.5-dimensional representations-a plan view plus heights-and a 180∘ field of view for large-scale scenes. Our experiments demonstrate accurate reconstructions of hidden rooms up to 3 meters in each dimension despite a small scan aperture (1.5-centimeter radius) and only 45 measurement locations.

Factors influencing chemotherapy knowledge in women with breast cancer.

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.
