Cell-based passive immunization for protection against SARS-CoV-2 infection.

BACKGROUND: Immunologically impaired individuals respond poorly to vaccines, highlighting the need for additional strategies to protect these vulnerable populations from COVID-19. While monoclonal antibodies (mAbs) have emerged as promising tools to manage infectious diseases, the transient lifespan of neutralizing mAbs in patients limits their ability to confer lasting, passive prophylaxis from SARS-CoV-2. Here, we attempted to solve this problem by combining cell and mAb engineering in a way that provides durable immune protection against viral infection using safe and universal cell therapy. METHODS: Mouse embryonic stem cells equipped with our FailSafe™ and induced allogeneic cell tolerance technologies were engineered to express factors that potently neutralize SARS-CoV-2, which we call 'neutralizing biologics' (nBios). We subcutaneously transplanted the transgenic cells into mice and longitudinally assessed the ability of the cells to deliver nBios into circulation. To do so, we quantified plasma nBio concentrations and SARS-CoV-2 neutralizing activity over time in transplant recipients. Finally, using similar cell engineering strategies, we genetically modified FailSafe™ human-induced pluripotent stem cells to express SARS-CoV-2 nBios. RESULTS: Transgenic mouse embryonic stem cells engineered for safety and allogeneic-acceptance can secrete functional and potent SARS-CoV-2 nBios. As a dormant, subcutaneous tissue, the transgenic cells and their differentiated derivatives long-term deliver a supply of protective nBio titers in vivo. Moving toward clinical relevance, we also show that human-induced pluripotent stem cells, similarly engineered for safety, can secrete highly potent nBios. CONCLUSIONS: Together, these findings show the promise and potential of using 'off-the-shelf' cell products that secrete neutralizing antibodies for sustained protective immunity against current and future viral pathogens of public health significance.

Nursing Students' Knowledge and Attitude Toward Cancer Survivorship.

The number of cancer survivors is expected to rise to up to 20 million by 2026. It is of utmost importance that nurses who provide survivorship care enhance their knowledge and skills to meet the needs of cancer survivors. The purpose of this project is to propose a pilot evidence-based educational project to incorporate the concept and framework of the survivorship care plan for nursing students. We evaluated feedback from nursing students for their knowledge and attitude on cancer survivorship care. A pilot educational project was given to 38 undergraduate students and 17 graduate students. Pre- and post-test feedback were collected from these students. Content analysis was used to analyze the data. At least 60% of both undergraduate and graduate nursing students had experience in either adult or pediatric oncology units. Only 11% of undergraduate and 18% of graduate students reported awareness of survivorship care plans. However, all of the students believed the survivorship care plan will be helpful for cancer patients. We recommend that it is imperative to incorporate the concept of cancer survivorship in the early stage of nursing education.

Adolescent cancer survivors' experiences of supportive care needs: A qualitative content analysis.

Supportive care is an important strategy that can help cancer survivors manage changes and problems during their follow-up care. Identifying patients' care needs is one of the primary steps of the nursing process to plan effective nursing interventions. The aim of this study was to explore adolescent cancer survivors' supportive care needs. Purposeful sampling was adopted to select 49 participants from hospitals to participate in face-to-face, semistructured interviews. The qualitative content analysis method was conducted for data analysis. Ten subcategories and four main categories - empathetic care, information about survival period, instrumental support, and cooperation in care - were extracted from the data. These four categories formed a major theme, "supportive care", as the primary healthcare need. This study highlights that supportive care should be developed collaboratively by family and healthcare providers to meet the needs of adolescent cancer survivors. Survivors' strengths and limitations should be identified, and then supportive care can be provided, such as giving appropriate information, enabling survivors to access supportive networks, and improving survivors' confidence and autonomy with their self-management.

Experience of Adolescent Survivors of Childhood Cancer about Self-Care Needs: A Content Analysis.

OBJECTIVE: In cancer care management, patients or their family are usually responsible for continuing health care. Achieving this goal requires identification of their self-care needs. The purpose of this study is to explore the perception of self-care needs of adolescent cancer survivors. METHODS: This study was conducted by the qualitative content analysis method. Participants were 19 adolescent childhood cancer survivors and six parents, nurses, physicians, and charity institution staff from children teaching hospitals in Iran. Participants were selected through purposeful sampling, and individual semistructured interviews were used for data collection. Graneheim and Lundman stages of content analysis were employed for data analysis. Data were managed with the MAXQDA10 software. RESULTS: Content analysis revealed nine subcategories as follows: (1) nutritional protection, (2) prevention from infection, (3) prevention from physical damage, (4) control over cancer recurrence, (5) informational needs, (6) pain management, (7) releasing positive thoughts, (8) continuing routine life, and (9) family protection. The first six subthemes were related to protection against physical distress, and the final three ones were related to protection against psychological distress. These two categories form one theme: "protective self-care need" as an essential self-care need in adolescent cancer survivors. CONCLUSIONS: Pediatric and school health nurses can prepare strategies to meet these needs by providing effective informational and psychosocial supports, and healthcare providers are able to check periodically the status of survivors care to provide second or third level of care to prevent escalation and incidence of the adverse outcomes of the disease.

Cancer Illness Perception and Self-Management of Chinese Patients.

OBJECTIVE: The purpose of this article is to examine the relationships of illness perception, self-care, self-efficacy, and self-care strategies and their effects on Chinese cancer patients' quality of life (QOL). METHODS: Questionnaires include data on demographic characteristics, illness perception, symptom self-care activity, and QOL. A secondary analysis was conducted on a sample of ethnic Chinese breast-and-colon cancer patients (n = 159) to examine multivariate associations. Descriptive statistics, bivariate correlational analysis, and hierarchical regression analysis were used to analyze quantitative data. RESULTS: The hierarchical regression model explained 43% of variance in QOL. Perceived illness consequence, personal control, and performance functioning status were found to be significant predictors in the model. Comparisons between breast-and-colon cancer patients showed that colon cancer patients significantly perceived higher levels of chronicity and negativity toward cancer than breast cancer patients. Conversely, breast cancer patients had significantly higher level of QOL and efficacy in making decision. Stress and overwork were the common perceived causes of cancer reported by these patients. CONCLUSIONS: These findings suggest that improving self-care efficacy and positive personal control can improve Chinese cancer patients' QOL. Variation in illness perceptions of cancer by different types of cancer should be considered in cancer survivorship planning and patient education.

The Effectiveness of Support Groups in Asian Breast Cancer Patients: An Integrative Review.

Cancer support group has been studied as an intervention to improve patient psychosocial well-being. The effectiveness of support groups among Asian breast cancer (BC) patients has been unclear and received limited attention to the evidence of its effectiveness. The social-cognitive processing theory underlies the principles of support groups and advocates that a positive, supportive social environment can improve cognitive processing. The purpose of this paper is to present an integrative review of research evidence on the effectiveness of cancer support groups with Asian BC patients. Empirical studies related to support group among Asian and Asian American BC patients published between 1982 and April 2014 are reviewed. There are 15 studies selected (12 from the Asian-Pacific region and 3 from Western countries). The review includes 1 qualitative study, 3 descriptive studies, 1 mixed method design, and 10 experimental or quasi-experimental studies. The support group intervention activities include psycho-educational program such as health education, problem-solving, and stress management. These studies support the effectiveness of support group in alleviating psychological distress and supporting quality of life of Asian BC women. Overall, there is limited research on the use and effectiveness of support groups with Asians cancer patients in Asia and in Western countries. Without accounting for Asian immigrants overseas, the Asian population is expected to grow from 4.3 to 5.3 billion by 2050. As cancer patients become more diverse due to global emigration, more rigorous studies examining the effectiveness of psychosocial intervention among transcultural cancer patients are needed.

Challenges in Cancer Self-management of Patients with Limited English Proficiency.

OBJECTIVE: This paper summarizes the barriers and challenges in cancer care reported from a validation project of a self-management intervention handbook from Chinese-American cancer patients with limited English proficiency (LEP). METHODS: Seven health-care providers (HCPs) and 16 Chinese-American cancer survivors with LEP were invited to validate a self-management intervention handbook through networking sampling method. Bilingual versions were developed and validated using the repeated translation process. Online and paper-based survey and interview were conducted to collect information on the perception of barriers and experiences on cancer care. Data were analyzed by the content analysis method. RESULTS: The HCPs reported a bilingual self-management handbook which is useful and feasible for patient self-management. The challenges in giving cancer care to LEP patients included: patients do not engage in discussion, different cultural health beliefs, unable to speak to patients in their primary language, and patients are less likely to discuss emotional and social challenges during treatments. The common barriers and experiences during cancer care included: limited understanding about treatment/medication and side effects, language barriers such as unable to communicate to make the decision, unable to understand information related to resources and do not know what questions to ask, and do not know what to expect during their cancer treatment. CONCLUSIONS: The current findings highlight the need of cancer self-management support for culturally diverse LEP cancer patients. Further research can include applying the supportive intervention to all LEP cancer patients.

Crim1 has cell-autonomous and paracrine roles during embryonic heart development.

The epicardium has a critical role during embryonic development, contributing epicardium-derived lineages to the heart, as well as providing regulatory and trophic signals necessary for myocardial development. Crim1 is a unique trans-membrane protein expressed by epicardial and epicardially-derived cells but its role in cardiogenesis is unknown. Using knockout mouse models, we observe that loss of Crim1 leads to congenital heart defects including epicardial defects and hypoplastic ventricular compact myocardium. Epicardium-restricted deletion of Crim1 results in increased epithelial-to-mesenchymal transition and invasion of the myocardium in vivo, and an increased migration of primary epicardial cells. Furthermore, Crim1 appears to be necessary for the proliferation of epicardium-derived cells (EPDCs) and for their subsequent differentiation into cardiac fibroblasts. It is also required for normal levels of cardiomyocyte proliferation and apoptosis, consistent with a role in regulating epicardium-derived trophic factors that act on the myocardium. Mechanistically, Crim1 may also modulate key developmentally expressed growth factors such as TGFßs, as changes in the downstream effectors phospho-SMAD2 and phospho-ERK1/2 are observed in the absence of Crim1. Collectively, our data demonstrates that Crim1 is essential for cell-autonomous and paracrine aspects of heart development.

Timing and sustainability of an exercise intervention in women with breast cancer during and after cancer treatment.

PURPOSE/OBJECTIVES: To compare changes in frequency, duration, and intensity of exercise behaviors over time in women with breast cancer between those who started their exercise intervention at the beginning of chemotherapy (EE) and those who started at the completion of chemotherapy (CE). DESIGN: A secondary data analysis of a randomized, controlled trial for exercise intervention. SETTING: Five cancer centers in the San Francisco Bay Area in California. SAMPLE: 66 outpatient women with breast cancer who were receiving chemotherapy. METHODS: Piecewise linear mixed models analysis was used to study changes in exercise behaviors over time in the EE group during and after treatment. In addition, linear mixed models analysis was used to examine changes between the EE and CE groups after treatment. Participants were in the trial for various length of time (EE group: 19-86 weeks; CE group: 6-43 weeks). MAIN RESEARCH VARIABLES: Exercise frequency, intensity, and duration. FINDINGS: In the EE group, weekly exercise duration increased significantly during treatment (p = 0.02). In addition, weekly exercise intensity increased significantly during treatment (p = 0.02) and decreased significantly after treatment (p = 0.003). After treatment, initial weekly exercise duration was significantly lower in the CE group than in the EE group (p = 0.01). No significant differences existed in frequency and intensity over time between the EE and CE groups. CONCLUSIONS: Women with breast cancer can sustain exercise behaviors when they start an exercise intervention in the beginning of chemotherapy treatment. IMPLICATIONS FOR NURSING: Strategies to support patients in maintaining their exercise habit may be needed during the post-treatment period.

Development of a Spanish HIV/AIDS Symptom Management Guidebook.

PURPOSE: To provide culturally appropriate HIV/AIDS patient care, it is important to develop symptom management patient education materials for patients with different cultural backgrounds. The purpose of this study was to develop a Spanish version of the Symptom Management Guidebook: Strategies for People Living with HIV/AIDS guidelines and verify its content, perceived feasibility, and usefulness with HIV/AIDS care providers and people living with HIV/AIDS in Puerto Rico. DESIGN: The Symptom Management Guidebook includes self-care strategies to manage 14 common HIV-related symptoms. The Spanish version was developed by adopting and translating through forward and backward translation methods. Seven HIV/AID Shealth care providers from San Juan, Puerto Rico, were invited to review and revise the contents. Ten people living with HIV/AIDS from a community AIDS clinic in San Juan participated in a focus group to review the guidebook and discussed its usefulness and feasibility for managing their symptoms. FINDINGS/RESULTS: Participants expressed positive responses and considered an educational guidebook as a helpful tool for self-managing their symptoms. DISCUSSION/CONCLUSIONS: Results suggested that this guidebook may be useful as an intervention strategy for symptom management in HIV/AIDS patients. IMPLICATIONS: Future research can include testing self-managing intervention and its outcomes in culturally diverse HIV/AIDS patients.

Symptoms, self-care, and quality of life of Chinese American patients with cancer.

PURPOSE/OBJECTIVES: To explore the cancer symptom experience, self-care strategies, and quality of life (QOL) among Chinese Americans during outpatient chemotherapy. DESIGN: Descriptive, exploratory cohort study. SETTING: An outpatient infusion unit at a public urban county medical center. SAMPLE: 25 Chinese-speaking patients with cancer completed the study. Participants were first-generation immigrants with low levels of acculturation; 88% could not read English; 64% had an annual household income of less than $20,000. METHODS: Participants completed a basic demographics data sheet, the Suinn-Lew Acculturation Scale, the Memorial Symptom Assessment Scale and Self-Care Diary weekly for three weeks, and the Multidimensional QOL Scale-Cancer and Short-Form 36 Health Survey at the start and end of one chemotherapy cycle. Study instruments were translated into Chinese. MAIN RESEARCH VARIABLES: Symptoms, self-care, QOL, and acculturation. FINDINGS: Participants reported experiencing about 14 symptoms weekly. Lack of energy, hair loss, dry mouth, sleep difficulty, and loss of appetite were reported most frequently. On average, about two self-care strategies per symptom were reported and were low to moderate in effectiveness. About 20% of the sample listed Chinese medicine as part of their self-care strategies. A moderate level of QOL was reported. CONCLUSIONS: Using translated standardized questionnaires can be a feasible method of data collection in studies with non-English-speaking patients. However, having well-trained, bilingual data collectors is important. More attention to long-term cancer self-management in minority patients with cancer is needed. IMPLICATIONS FOR NURSING: Further research is needed with larger samples, more efficient community-based recruitment strategies, and the development and testing of culturally sensitive interventions.

HIV symptoms.

People with HIV/AIDS are a vulnerable group whose symptoms can seriously affect their quality of life. HIV/AIDS symptoms can result from the disease itself, from secondary complications of the disease, or from side-effects of highly active antiretroviral therapy (HAART) and other medications related to comorbidities. HIV symptoms are the single most important indicators for patients and practitioners. Symptoms prompt patients to seek medical attention and provide health care providers with essential clues about changes in health status and quality of life. Despite increased recognition of the importance of addressing symptoms among people with HIV/AIDS, few studies have examined the management of HIV symptoms. This chapter introduces HIV symptoms, reports on the methods of review, provides an overview of contextual issues including the literature on symptoms, issues related to symptom measures, theoretical foundations on symptom management, HIV-specific measures, non-HIV-specific measures, translation of findings into practice, and implications for future research and policy.

Self-care strategies and sources of information for HIV/AIDS symptom management.

BACKGROUND: Self-care is one of the challenges that people with HIV/AIDS face in the long-term symptom management of the disease. OBJECTIVE: To identify the category schemes of self-care strategies and sources of information for symptom management reported by HIV-positive individuals. METHODS: A secondary analysis was conducted in a large dataset of an HIV/AIDS symptom management study. Narrative data of symptom self-care management strategies and sources of information for symptom management were analyzed by a content analysis technique to identify category schemes. The 359 participants in the study reported 776 symptom self-care strategies and 526 sources of information for these strategies. RESULTS: The symptom self-care management strategies were summarized into eight categories: medications (23.45%), self-comforting (15.21%), complementary treatments (14.69%), daily thoughts and activities (12.89%), diet changing (10.95%), help seeking (9.28%), spiritual care (6.83%), and exercise (6.70%). There were four categories of information sources: self (34.41%), healthcare provider (27.95%), personal network (19.20%), and community (18.44%). The category schemes had moderate to high interrater reliability (Cohen's kappa:.49-1.00 for self-care strategy and .70-.87 for source of information). Most of the self-care strategies were perceived as helpful. Except for complementary treatments, self-care strategies were used differently among people with the six most frequently occurring symptoms (chi2 [5, n = 286] = 28.53-79.89). DISCUSSION: The eight categories of self-care strategies identified in this study showed that people with HIV/AIDS not only seek the help of medications, but also follow a wide array of other self-developed or self-taught nonpharmaceutical strategies to allay their symptoms.

Linking HIV/AIDS clients' self-care with outcomes.

The self-care practice of HIV/AIDS patients has become an important topic to help HIV/AIDS patients maintain their maximum level of well-being in chronic illness management. This article presents a self-care outcomes model that is applicable to HIV/AIDS nursing practice and research, and it identifies attributes and outcomes related to HIV/AIDS patients'self-care. The self-care outcomes model was developed based on the Outcomes Model for Health Care Research and literature review. Key variables related to HIV/AIDS self-care were summarized and discussed based on nine dimensions: client inputs, client processes, client outcomes, provider inputs, provider processes, provider outcomes, setting inputs, setting processes, and setting outcomes. This article reveals that self-care in HIV/AIDS is complex and may be influenced by many factors relating to individual, family, and health care system. More research with advanced multivariate statistical models and randomized controlled trial design will help determine the effectiveness of self-care strategies and interventions.

Testing a predictive model of the use of HIV/AIDS symptom self-care strategies.

Several types of self-care strategies have been reported by patients with HIV/AIDS to manage their HIV/AIDS related symptoms. However, little research has examined the factors influencing the use of different HIV symptom self-care strategies. This paper presents the results of testing a predictive model of the use of eight types of symptom self-care strategies: medications, complementary treatments, self-comforting, daily thoughts/activities, changing diet, help-seeking, exercise, and spiritual care. Logistic regression tests were used to examine the likelihood of using the eight types of symptom self-care strategies that were summarized and categorized from the questionnaires reported by patients with HIV/AIDS (n = 359). Sociodemographic variables (age, gender, race, education, injection drug use, insurance status, income status) and disease-related variables (taking antiretroviral medications, symptom intensity, symptom bothersomeness, impact of symptom on daily life) were selected as predictive variables. Logistic regression analysis demonstrated that race (white vs. non-white) was a significant predictor for the use of medications (odds ratio [OR] = 0.55, 95% confidence interval [CI] = 0.33-0.92), self-comforting (OR = 2.17, 95% CI = 1.24-3.79), help seeking (OR = 5.71, 95% CI = 2.57-12.70), and spiritual care (OR = 5.09, 95% CI = 1.81-14.30). In addition, symptom intensity significantly predicted the use of medications (OR = 1.22, 95% CI = 1.05-1.40) and gender significantly predicted the use of spiritual care (OR = 3.76, 95% CI = 1.71-8.25). Racial difference is the predominant predictor for the use of symptom self-care strategies. The cultural differences in the use of symptom self-care strategies should be considered in symptom management.

Self-care management of anxiety and fear in HIV disease.

The purpose of this study is to describe the frequency and correlates of self-reported anxiety and fear and the self-care behaviors used to manage these symptoms. Data were collected in a convenience sample (N = 422) of HIV-positive subjects. Demographic and disease-related variables were compared for those who did and did not report anxiety and fear. Anxiety and fear were the most frequently reported symptoms (17.3%, n = 73). There were significant differences on gender, level of education, and the use of antiretroviral medications. Self-care behaviors (n = 212) for anxiety and fear were grouped into seven categories: using activities for distraction = 25%, talking to others = 21%, using alternative/complementary therapies = 18%, taking prescribed medications = 10%, using self-talk = 9%, using substances = 9%, and using avoidance behaviors = 7%. Anxiety and fear are commonly experienced by people with HIV/AIDS. Self-care strategies are imperative in the management of these clinical manifestations.

Self-care for fatigue in patients With HIV.

PURPOSE/OBJECTIVES: To identify when fatigue is reported as a problem by people who are HIV positive, what the perception of fatigue is, and which self-care behaviors are used and with what efficacy. DESIGN: Multisite descriptive study. SETTING: University-based AIDS clinics, community-based organizations, and homecare agencies located in cities across the United States, in Norway, and through a university Web site. SAMPLE: Convenience sample of 422 self-identified people who are HIV positive. MAIN RESEARCH VARIABLES: Symptom description, symptom relief, symptom help, and self-care strategies. FINDINGS: The sixth most reported symptom in this study, fatigue, was treated with a variety of self-designed strategies. In only three instances was consultation with a healthcare provider (i.e., physician) or an injection (medication not defined) mentioned. The most frequently used interventions were supplements, vitamins, and nutrition followed by sleep and rest; exercise; adjusting activities, approaches, and thoughts; distraction; and complementary and alternative therapies. In addition to self-designed strategies, the media and friends and family were sources of information. CONCLUSIONS: Fatigue was reported less frequently in this study than in other HIV-, AIDS-, or cancer-related studies. This may be an artifact of the study design. The use of informal networks for assistance, let alone the prevalence of unrelieved fatigue, indicates the need for more attention to this problem among people with AIDS. IMPLICATIONS FOR NURSING: Careful assessment of the pattern of fatigue and its onset, duration, intervention, and resolution is required if the varied types of fatigue are to be identified and treated successfully.
