RESUMO

BACKGROUND: Psychological distress is a prevalent unpleasant experience faced by many cancer patients. However, the psychological distress among gastrointestinal (GI) cancer patients is scarcely explored. Moreover, the association between psychological distress and quality of life in different genders has yet to be explored. AIMS: To explore the psychological distress among GI cancer patients and examine its association with quality of life among different genders. METHODS: This study was a cross-sectional study. A total of 237 gastrointestinal cancer patients completed the distress thermometer and the Functional Assessment of Chronic Illness Therapy-General. RESULTS: The mean score of psychological distress of the participants was 3.04 (SD = 2.90). A greater proportion of female gastrointestinal cancer patients (52.8%) had clinically relevant psychological distress compared to males (35.9%). The quality of life was negatively associated with their psychological distress (B = - 1.502, 95%CI: - 2.759 to - 0.245, p = 0.019) among gastrointestinal cancer patients. Such association was stronger among males compared to females in gastrointestinal cancer patients (Interaction term, B = - 1.713, 95%CI: - 3.123 to - 0.303, p = 0.017). CONCLUSIONS: These findings suggest that healthcare providers should attach their attention to gastrointestinal cancer patients' psychological distress, especially females. Longitudinal studies could adopted to track the changes in psychological distress and its association with quality of life over time among different genders. In future intervention studies, the focus of psychological interventions needs to be gender-specific.

RESUMO

Importance: Psychoeducational interventions (PEIs), which provide both information and emotional and psychosocial support, may address the unmet needs of the caregivers of adolescent and young adult patients with cancer. Objective: To explore the effects of an instant messaging-delivered PEI on anxiety, depression, quality of life (QOL), and coping and determine whether the intervention reduces caregivers' unmet needs. Design, Setting, and Participants: This randomized clinical trial using an intention-to-treat protocol was conducted from April 1 to September 14, 2022, in a tertiary cancer hospital in China and included caregivers of patients diagnosed with cancer at age 15 to 39 years recruited using convenience sampling. Intervention: Caregivers were allocated 1:1 using a randomized block scheme to the intervention or control group. The intervention group received a 5-week PEI and usual care, whereas the control group received only usual care. The PEI was delivered through articles and calls through an instant messaging application. Main Outcomes and Measures: The primary outcomes were changes in the levels of caregivers' anxiety and depression, measured using the 7-Item Generalized Anxiety Disorder Scale and the Patient Health Questionnaire 9, respectively. The secondary outcomes were changes in the levels of caregivers' QOL, coping, and unmet needs. Results: Of the 160 participants, 92 (57.5%) were male; mean (SD) age was 40.27 (8.33) years. Compared with the control group, the intervention group had significantly greater reduction in severity of anxiety (B = -3.231; 95% CI, -4.746 to -1.716; P < .001) and depression (B = -3.253; 95% CI, -5.052 to -1.454; P < .001), smaller reduction in QOL (B = 13.574; 95% CI, 0.488-26.661; P = .04), and greater reduction in unmet needs (B = -12.136; 95% CI, -18.307 to -5.965; P < .001) after the intervention. Twelve weeks after baseline, the intervention group demonstrated a significantly greater reduction only in severity of anxiety (B = -1.890; 95% CI, -3.382 to -0.397; P = .01). Conclusions and Relevance: In this randomized clinical trial of a mobile instant messaging-delivered PEI, caregivers' unmet needs, anxiety, and depression decreased significantly and QOL declined at a significantly slower rate immediately after the intervention in the intervention group compared with the control group. A sustained effect on anxiety was observed 12 weeks after baseline. Trial Registration: Chinese Clinical Trial Registry identifier: ChiCTR2200055951.

RESUMO

This qualitative study aimed to gain a deep understanding of the spiritual needs of patients with advanced cancer. A qualitative study using semi-structured interviews was conducted. The interviews were audio-recorded, transcribed verbatim, and subjected to thematic analysis. Two researchers coded the interviews independently in NVivo 12 plus and developed major themes and subthemes by inductive and constant comparison. This study was conducted in the inpatient ward of a tertiary cancer hospital in Hunan Province, Chinese Mainland. Eligible participants with advanced cancer were recruited using the purposive sampling method. The sample size was determined by data saturation. All interviews were conducted face-to-face individually from May 2021 to July 2021. A total of 13 patients with advanced cancer patients were interviewed. Six themes were identified, namely being treated as normal and independent individuals, receiving and giving love, seeking inner peace, connecting with spiritual sources, finding meaning and purpose, and preparing for death. Different categories of spiritual needs of patients with advanced cancer were identified in this study. Healthcare professionals need to develop interventions that aim to meet patients' spiritual needs.

RESUMO

Objective: While there are limited studies addressing palliative care quality in China, the availability of an effective set of care quality indicators is scarce. This study aimed to develop a comprehensive set of quality indicators for palliative care in China. Methods: Conducting a systematic literature search across databases and guideline websites from inception to October 2020, combined with qualitative interviews, we established a preliminary pool of indicators. Subsequently, two rounds of Delphi expert consultation surveys were administered to 19 multidisciplinary experts (specializing in clinical nursing/medicine, nursing/medicine management, and health care administration, as well as those engaged in teaching and research) from 12 provinces in Mainland China (three each from North, East, and South China, and four from Central China) via email from March to June 2021. The analytic hierarchy process was employed to determine indicator weights. Results: Both rounds of expert consultation yielded a 100% positive coefficient, with expert authority coefficient values of 0.91 and 0.93, respectively. Kendall coefficient of concordance values for the two rounds were 0.148 and 0.253 (P < 0.001), indicating consensus among experts. Consequently, 71 quality indicators deemed important in the Chinese palliative care setting were identified, comprising 22 structure indicators, 35 process indicators, and 14 outcome indicators. Conclusions: This study established an evidence-based set of quality indicators, addressing previously unmet needs and providing a novel approach to assessing and monitoring palliative care quality. Furthermore, ongoing refinement and integration with the evolving social context are warranted.

RESUMO

There is increasing interest in understanding exercise as a potential treatment for cancer-related fatigue (CRF); however, rarely research has been conducted on more aggressive cancers with short survival, such as liver cancer. The purpose of this study was to provide educational ideas for insufficient exercise and provide clues for the design of effective and safe exercise intervention programs with high compliance in patients of advanced liver cancer in the future. Participants were recruited from a tertiary cancer hospital using convenience sampling. All participants were asked to complete self-report questionnaires that assessed their medical and demographic variables, exercise habits and CRF during their hospitalization in the interventional department. Spearman's correlation analysis and Nonparametric test was used to explore correlations between exercise subgroups and CRF. The Baron and Kenny's Approach was used to investigate the mediating effect of exercise index between P-EX and CRF. 207 out of 255 participants were enrolled in this study, with an average age of 55.4 years. The CRF score was 33 (28, 36), and 93.2% had insufficient exercise. Exercise frequency (≥ 3 Times/week) (Z = 4.34, p = 0.037) and maintaining exercise trend (Z = 15.85, p = 0.001) had a positive effect on CRF. P-EX had a great impact on exercise index and affecting CRF directly. Participants in the study showed serious fatigue and insufficient exercise. Exercise education can be initiated earlier, particularly those without regular exercise experience. Sustained light exercise, compliant with exercise habits and interests, three times a week may be a practical way to reduce the risk of CRF in advanced liver cancer.

RESUMO

BACKGROUND: The purpose of this study was to assess willingness of advanced cancer patients to receive palliative care and its determinants at Cancer Care Centre in Kilimanjaro Christian Medical Centre Northern Tanzania. OBJECTIVE: The purpose of this study was to assess willingness of advanced cancer patients to receive palliative care and its determinants at Cancer Care Centre in Kilimanjaro Christian Medical Centre Northern Tanzania. METHODS: This was an institution-based cross-sectional study and the target population was all advanced cancer patients attending care at Cancer care Centre in Northern Tanzania. Data was collected using a structured questionnaire and analysed using Stata for windows 15. A descriptive analysis was conducted to summarize the data using mean standard deviation, while categorical data was summarized using frequency and percentages. Both bivariate and multivariate logistic regression analysis was used to determine the predictors associated with willingness to receive palliative care. RESULTS: The results showed that more than half of the respondents had willingness to accept palliative care. The degree of willingness PC among advanced cancer patients was high 60.6% (95%CI: 55.8-65.3). The predictors which remained significant associated with willingness to receive palliative care in multivariate analysis were the knowledgeable of palliative care [AOR: 2.86; 95%CI: 1.69-4.85] and high perceived benefits of palliative care [AOR: 3.58; 95%CI: 2.12-6.04]. CONCLUSION: Willingness to accept palliative care services was more than half of the patients just 60.6% among patients with advanced cancer from the study site. Advanced age of a patient, occupations, better knowledge, and perceived benefits for palliative care was the significant predictor for patients' willingness to accept palliative care.

RESUMO

Objective: Nurses play a crucial role in cancer control. Prior reviews presented the effectiveness of nursing interventions such as tobacco cessation counseling and cervical cancer screening but did not focus on low- and middle-income countries (LMICs). This scoping review addresses a gap in the literature by describing the roles and activities of nurses in cancer prevention and early detection in LMICs. Methods: Following Arksey and O'Malley's scoping review framework, we searched seven databases using subject headings and keywords from 1990 to January 2021 and updated in April 2022. The reference lists of relevant studies were also searched. Two reviewers independently screened the relevance of studies through Rayyan, assessed full text articles, and extracted data using a Google Form. Conflicts were resolved by a third reviewer. Results: A total of 180 studies were included, representing all six World Health Organization regions and 48 LMICs. The largest number of studies were from the African region (n â€‹= â€‹72), the Americas (n â€‹= â€‹49), and South-East Asia region (n â€‹= â€‹29). The main nursing roles featured were patient/community education (n â€‹= â€‹113), history taking and cancer risk assessment (n â€‹= â€‹63), performing screening exams (n â€‹= â€‹136), care coordination (n â€‹= â€‹57), and training other healthcare professionals (n â€‹= â€‹9). Conclusions: This scoping review provides a comprehensive picture of nurses' role in cancer prevention and early detection in LMICs, across all six World Health Organization regions. Additional cancer workforce data sources at the country level are needed to fully understand the activities of nurses in cancer prevention. Future research is also needed to measure the impact of nursing educational and other interventions in both primary and secondary cancer prevention.

RESUMO

In highly intensive greenhouse vegetable production, soil acidification was caused by excessive fertilization, increasing cadmium (Cd) concentrations in the vegetables, which bears environmental hazards and is a negative influence on vegetables and humans. Transglutaminases (TGases), a central mediator for certain physiological effects of polyamines (PAs) in the plant kingdom, play important roles in plant development and stress response. Despite increased research on the crucial role of TGase in protecting against environmental stresses, relatively little is known about the mechanisms of Cd tolerance. In this study, we found, TGase activity and transcript level, which was upregulated by Cd, and TGase-induced Cd tolerance related to endogenous bound PAs increase and formation of nitric oxide (NO). Plant growth of tgase mutants was hypersensitive to Cd, chemical complementation by putrescine, sodium nitroprusside (SNP, nitric oxide donor) or gain of function TGase experiments restore Cd tolerance. α-diflouromethylornithine (DFMO, a selective ODC inhibitor) and 2-4-carboxyphenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO, NO scavenger), were respectively found declined drastically endogenous bound PA and NO content in TGase overexpression plants. Likewise, we reported that TGase interacted with polyamine uptake protein 3 (Put3), and the silencing of Put3 largely reduced TGase-induced Cd tolerance and bound PAs formation. This salvage strategy depends on TGase-regulated synthesis of bound PAs and NO that is able to positively increase the concentration of thiol and phytochelatins, elevate Cd in the cell wall, as well as induce the levels of expression Cd uptake and transport genes. Collectively, these findings indicate that TGase-mediated enhanced levels of bound PA and NO acts as a vital mechanism to protect the plant from Cd-caused toxicity.

RESUMO

OBJECTIVES: Many factors are related to oncology nurses' professional values. However, the evidence on the relevance of professional values among oncology nurses in China remains sparse. This study aims to investigate the relationship between depression, self-efficacy, and professional values among Chinese oncology nurses and analyze the mediating effect of self-efficacy on this association. METHODS: It was a multicenter cross-sectional study designed with the STROBE guidelines. An anonymous online questionnaire recruited 2530 oncology nurses from 55 hospitals in six provinces of China between March and June 2021. Measures included self-designed sociodemographic and fully validated instruments. Pearson correlation analysis was employed to explore the associations between depression, self-efficacy, and professional values. Bootstrapping analysis by the PROCESS macro was used to examine the mediating effect of self-efficacy. RESULTS: The total scores of depression, self-efficacy, and professional values of Chinese oncology nurses were 52.75 ± 12.62, 28.39 ± 6.33, and 101.55 ± 20.43, respectively. About 55.2% of Chinese oncology nurses were depressed. Chinese oncology nurses' professional values were generally intermediate. Their professional values were negatively related to depression and positively correlated with self-efficacy, while depression was negatively related to self-efficacy. Moreover, self-efficacy partially mediated the relationship between depression and professional values, accounting for 24.8% of the total effect. CONCLUSIONS: Depression negatively predicts self-efficacy and professional values, and self-efficacy positively predicts professional values. Meanwhile, depression in Chinese oncology nurses has an indirect effect on their professional values through self-efficacy. Nursing managers and oncology nurses themselves should develop strategies aimed at relieving depression and improving self-efficacy to strengthen their positive professional values.

RESUMO

Background: The provision of sexual healthcare plays an integral role in the field of oncology nursing. However, limitations in the knowledge, attitude, and practice perspectives of oncology nurses require detailed study. Aim: In this study the authors sought to describe the knowledge, attitude, and practice of oncology nurses regarding sexual healthcare from a nationwide perspective and to explore the factors that influence them. Methods: This was a cross-sectional descriptive study using stratified random sampling of certified oncology nurses from 55 hospitals in 6 provinces in Central South China. In total, 2530 nurses participated and completed the Knowledge, Attitude and Practice questionnaire of Sexual Health Care (KAP of SHC), the Nurses Clinic Communication Competency Scale, the Nurses Professional Values Scale, and the General Self-efficacy Scale. Multivariate linear regression was used to explore influencing factors. Outcomes: The primary variable was the knowledge, attitude, and practice of sexual healthcare provision. Secondary variables included professional value, clinical communication competency, self-efficacy, and demographic factors. Results: The median KAP of SHC score was 139 (possible range 72 to 288). Attitude of SHC scored highest, followed by knowledge and practice scores. Professional values were positively associated with knowledge (odds ratio [OR] = 0.057; 95% CI: 0.023-0.091; P < .01) and attitude (OR = 0.319; 95% CI: 0.268-0.370, P < .01) of SHC. Clinical communication competency was only positively related to the attitude of SHC (OR = 3.960; 95% CI: 2.701-5.218, P < .01). Self-efficacy was positively related to KAP and the knowledge (OR = 0.616; 95% CI: 0.506-0.725, P < .01), attitude (OR = 0.187; 95% CI: 0.052-0.322, P < .01), and practice (OR = 0.840; 95% CI: 0.735-0.944, P < .01) of SHC. Clinical Implications: Knowledge assistance, attitude training, and practice coaching resources must be on the agenda to optimize professional practice for oncology nurses. Strengths and Limitations: This study provides data based on the Knowledge, Attitude, Belief and Practice (KABP) model in a nationwide sample of oncology nurses. In addition, the relationship between self-efficacy and KAP of SHC has been explored for the first time. The limitations are that this study may have some bias and did not take into account mediating relationships. Conclusions: Oncology nurses exhibit moderate levels of KAP of SHC. It is noteworthy that self-efficacy and position are the only 2 factors that influenced all aspects of KAP of SHC.

RESUMO

PURPOSE: Spiritual well-being is a critical element of individuals' quality of life and is overestimated by healthcare providers. A body of evidence is conducted on the spiritual well-being of cancer patients, but few on gastrointestinal (GI) cancer patients, which constitute a great proportion of the cancer burden. This study aimed to investigate the spiritual well-being of GI cancer patients and its association with hope and meaning in life. METHODS: A cross-sectional study was conducted. A total of 237 GI cancer patients were recruited in this study by convenience sampling in 2022. All the participants completed the sociodemographic and clinical characteristics, Functional Assessment of Chronic Illness Therapy-Spiritual Wellbeing, Herth Hope Index, and Meaning in Life Questionnaire. Multiple linear regression analysis was conducted to explore the associated factors with spiritual well-being. RESULTS: The GI cancer patients experience a relatively low level of spiritual well-being (mean = 31.54, SD = 9.84). The presence of meaning (B = 0.847, 95% CI [0.640, 1.054], p < 0.001), inner positive readiness and expectancy (B = 1.033, 95% CI [0.548, 1.518], p < 0.001), residence (B = 2.828, 95% CI [1.045, 4.612], p = 0.002), and search for meaning (B = 0.247, 95% CI [0.072, 0.422], p = 0.006) were associated with the spiritual well-being of GI cancer patients. These four associated variables accounted for 57.8% of the variance in spiritual well-being (F = 81.969, p < 0.001). CONCLUSION: The spiritual well-being of GI cancer patients was relatively low and associated with the presence of meaning, inner positive readiness and expectancy, residence, and search for meaning. Healthcare professionals may consider improving GI patients' spiritual well-being by enhancing their sense of meaning in life and inner positive readiness and expectancy.

RESUMO

BACKGROUND: Little is known about the psychoeducational interventions for caregivers of adolescent and young adult (AYA) cancer patients. OBJECTIVE: To evaluate the feasibility and acceptability of a needs-oriented psychoeducational intervention among caregivers of AYA cancer patients. METHODS: In this 2-arm (parallel-group), pilot randomized controlled trial, participants were randomized to the intervention or control group. Participants in the control group received usual care, whereas those in the intervention group received a needs-oriented psychoeducational intervention via WeChat as well as the usual care. Feasibility was evaluated on recruitment, attrition, and adherence rates and the data collection process. Acceptability was assessed based on participants' satisfaction with and perceived usefulness of the intervention, collected using a questionnaire. In addition, a semistructured interview was conducted to explore their experiences. RESULTS: Twenty-four caregivers of AYA cancer patients were recruited, with a consent rate of 61.5%. The attrition and response rates 5 weeks after baseline were 8.3% and 91.7%. Among the 12 participants in the intervention group, 10 (83.3%) completed all of the 5 weekly sessions. Most of the participants were satisfied with the program and perceived its usefulness. The semistructured interviews revealed 3 major categories: facilitators of participation, perception of the intervention, and perceived benefits. CONCLUSIONS: The needs-oriented psychoeducational intervention delivered through WeChat is feasible for and acceptable to caregivers of AYA cancer patients. A full-scale study is warranted to examine the effects of this intervention on caregivers' health outcomes. IMPLICATIONS FOR PRACTICE: The WeChat-based, needs-oriented psychoeducational intervention may be beneficial to improve caregivers' health outcomes.

RESUMO

Poly-ADP-ribose (PAR) is a natural type of polymer derived from enzymatic reactions catalyzed by cellular poly(ADP-ribose) polymerases (PARPs). Given its notable solubility and biocompatibility, the PAR polymer may function as effective carriers for therapeutics in addition to modulating biomolecular interactions in cells. To explore its therapeutic potential, we herein developed a PAR polymer-based bispecific antibody targeting both human epidermal growth factor receptor 2 (HER2) and T-cell CD3 antigens. This was accomplished by conjugating anti-HER2 and anti-CD3 monoclonal antibodies to azido-functionalized PAR polymers through click chemistry. The generated PAR polymer-anti-HER2/anti-CD3 antibody conjugate could not only bind specifically to both HER2- and CD3-expressing target cells but also display potent cytotoxicity against HER2-positive breast cancer cells in the presence of non-activated human peripheral blood mononuclear cells (PBMCs). Functionalized PAR polymers provide a new strategy for synthesizing bispecific antibodies and may enable generation of PAR polymer-based conjugates with unique pharmacological activities for biomedical applications.

RESUMO

Poly-ADP-ribose (PAR) is a naturally occurring form of polymers synthesized through enzymatic reactions catalyzed by poly(ADP-ribose) polymerases (PARPs). It is known for regulating various important cellular signaling pathways and processes. As a water soluble and biocompatible type of polymer, PAR may hold promise for safe and efficient delivery of therapeutics. To explore the therapeutic potential of PAR polymers, we herein generate PAR polymers conjugated with human granulocyte colony-stimulating factor (GCSF) protein by harnessing human PARP1-catalyzed auto-poly-ADP-ribosylation and a clickable analogue of nicotinamide adenine dinucleotide (NAD+). The resulting PAR polymer-based conjugate with multivalent GCSF ligands exhibits a potent cell proliferative activity. Notably, mice treated with a single dose of the PAR polymer-GCSF conjugate show sustained high levels of neutrophil in blood for 11 days, demonstrating excellent in vivo efficacy. Functionalized PAR polymers may provide new scaffolds for conjugating with therapeutic proteins or peptides toward improved pharmacological activities.

RESUMO

OBJECTIVE: The purpose of this study was to investigate death anxiety status among Chinese patients with cancer and identify factors that affect death anxiety. DESIGN: Cross-sectional study. SETTING: Changsha, Hunan Province, China. PARTICIPANTS: A total of 286 inpatients diagnosed with cancer were randomly recruited from a tertiary cancer centre and completed the questionnaires between January and June 2021. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was the status of death anxiety. The secondary outcomes were the factors that affect death anxiety among Chinese patients with cancer. METHODS: A total of 286 Chinese patients with cancer were recruited from a tertiary cancer hospital to complete the demographic and clinical characteristics questionnaire, Templer's Death Anxiety Scale, Acceptance and Action Questionnaire-second edition, and Meaning in Life Questionnaire from January to June 2021. Data were analysed using t-test, analysis of variance, Kruskal-Wallis H test, Pearson correlation analysis and multiple linear regression analysis. RESULTS: On average, patients with cancer scored 7.72±4.17 for death anxiety, 25.71±9.69 for experiential avoidance and 45.19±8.22 for meaning in life. Ultimately, the statistically significant factors influencing death anxiety were education levels, insurance, pain scores, experiential avoidance and meaning in life. These factors explained 40.6% of the difference in death anxiety. CONCLUSIONS: Patients with cancer in China experienced a high level of death anxiety. This study showed that experiential avoidance and meaning in life were important factors that affected death anxiety in patients with cancer. Further studies should be conducted to explore effective interventions to prevent experiential avoidance and increase meaning in life for patients with cancer. Attention should be paid to patients without insurance but with lower education levels and higher pain scores to ultimately relieve death anxiety and improve their quality of life.

RESUMO

Objective: Meaning in life (MIL) and family cohesion are important concerns for the palliative care population; however, evidence of the relationship between MIL and family cohesion is scarce. Therefore, this study aimed to examine the relationship between MIL and family cohesion and explore the factors that influence MIL among the palliative care population. Methods: In this cross-sectional study, 205 patients with advanced cancer were recruited from two palliative care units in China. Data were collected using the meaning in life scale (MiLS), the family cohesion subscale of the Family Adaptability and Cohesion Scale, second edition, Chinese version, and the Karnofsky Performance Status Scale (KPS). Multivariate linear regression models were used to examine the relationship between family cohesion and perceived MIL and identify the potential factors of participants' MiLS score. Results: The mean MiLS score was 100.90 (SD â€‹= â€‹9.17). The results showed that family cohesion (r â€‹= â€‹0.313, P â€‹< â€‹0.001) and KPS scores (r â€‹= â€‹0.311, P â€‹< â€‹0.001) were positively correlated with MiLS scores. Multivariate linear regression revealed that MIL was significantly influenced by family cohesion, KPS score, sex, religiosity, whether participants lived alone, and their medical insurance payment method (Adjust R 2 â€‹= â€‹28.4%, F â€‹= â€‹6.281, P â€‹= â€‹0.013). Conclusions: Our findings indicate a positive relationship between family cohesion and MIL, suggesting that clinicians should consider increasing patients' family cohesion as an approach to enhance perceived MIL.

RESUMO

Objective: To assess unmet needs, anxiety, depression, and quality of life of caregivers of adolescents and young adults with cancer and examine their associations. Methods: A total of 282 caregivers of adolescents and young adults with cancer were recruited by convenience sampling at a tertiary cancer hospital in Chinese Mainland. The participants' unmet needs, anxiety, depression, and quality of life were assessed using self-reported questionnaires. Hierarchical regression analyses were conducted to examine associations between unmet needs and health outcomes. Results: The five most prevalent high unmet needs were related to 'worries about future' and 'information', including dealing with not knowing what lies in the future (n â€‹= â€‹161, 57.1%), dealing with worry about the cancer getting worse (n â€‹= â€‹151, 53.5%), dealing with worry about the cancer coming back (n â€‹= â€‹147, 52.1%), finding information about complementary or alternative therapies (n â€‹= â€‹137, 48.6%), and finding information about the long-term side effects of treatments and medicines (n â€‹= â€‹126, 44.7%). Around 40% of the caregivers reported moderate to severe anxiety and depression. After adjusting for sociodemographic and clinical characteristics, personal and emotional needs, healthcare access and continuity, and financial needs remained significantly associated with anxiety, depression, or quality of life. Conclusions: Nurses need to be aware of the unmet needs of caregivers of adolescents and young adults with cancer. More effort is needed to identify services and interventions that address the unmet needs, particularly personal and emotional, healthcare access and continuity, and financial needs, to improve the caregivers' health outcomes.

RESUMO

Financial toxicity (FT) has been used to describe patients' whole economic experience that negatively impacts their well-being. FT's adverse effects on patients' health outcomes have been reported by reviews conducted in Western countries. However, these findings may not apply to patients in China. This review aimed to analyze existing data on the measures, prevalence, risk factors, and health-related consequences of FT in China. We searched 10 databases in May 2021 and again in January 2022 using Medical Subject Headings terms and free text. We also searched the reference lists of included articles. Two reviewers independently screened the studies, extracted the data, and assessed the quality of the included studies using the Joanna Briggs Institute Critical Appraisal Checklist. Thirty-one articles describing 30 studies were included in the analysis. Various FT measures were identified, but the number of validated measures was limited. The prevalence of material, psychological, and behavioral FT was 6%-78%, 61%-84%, and 10%-79%, respectively. We identified common risk factors and health-related consequences associated with FT similar to those reported in previous reviews. We also identified several potential risk factors (eg, increased length of hospital stay and larger household size) and consequences (patients' self-perceived burden) in a limited number of studies. Our findings show an urgent need for more data on the prevalence, risk factors, and health-related consequences associated with FT in Chinese cancer patients, and these data must be generated using validated measures.

RESUMO

Exosomes are cell-derived nanovesicles involved in regulating intercellular communications. In contrast to conventional nanomedicines, exosomes are characterized by unique advantages for therapeutic development. Despite their major successes in drug delivery, the full potential of exosomes for immunotherapy remains untapped. Herein we designed genetically engineered exosomes featured with surfaced-displayed antibody targeting groups and immunomodulatory proteins. Through genetic fusions with exosomal membrane proteins, Expi293F cell-derived exosomes were armed with monoclonal antibodies specific for human T-cell CD3 and epidermal growth factor receptor (EGFR) as well as immune checkpoint modulators, programmed death 1 (PD-1) and OX40 ligand (OX40L). The resulting genetically engineered multifunctional immune-modulating exosomes (GEMINI-Exos) can not only redirect and activate T cells toward killing EGFR-positive triple negative breast cancer (TNBC) cells but also elicit robust anti-cancer immunity, giving rise to highly potent inhibition against established TNBC tumors in mice. GEMINI-Exos represent candidate agents for immunotherapy and may offer a general strategy for generating exosome-based immunotherapeutics with desired functions and properties.

RESUMO

PURPOSE: Family caregivers of palliative cancer patients experience various supportive care needs. Appropriate self-reported instruments with robust psychological properties are required to identify these needs of family caregivers. Therefore, we conducted a systematic review to identify self-reported supportive care needs assessment instruments for family caregivers of palliative cancer patients and assess their contents, psychometric properties, and applicability. METHODS: Systematic searches were conducted in six English databases and four Chinese databases from inception to October 2020 and updated in June 2021. The instruments identified were evaluated using an 18-item checklist consisting of six domains: conceptual model, content validity, reliability, construct validity, scoring and interpretation, and respondent burden and presentation. RESULTS: Six articles, describing four self-reported needs assessment instruments, were included in the review. These instruments varied significantly in terms of contents, constructs, scoring methods, and applicability. Three of these instruments were developed to assess the comprehensive supportive care needs of family caregivers, while one was specifically developed to assess the spiritual needs of family caregivers. With respect to psychometric properties, none of the instruments identified met all the criteria. Three major shortcomings were identified, namely, lack of longitudinal validity, lack of a strategy for interpreting missing data, and lack of a description of the literacy level required to understand the questions. Additionally, the instrument development processes assessed in this study lacked qualitative elements. CONCLUSIONS: End-users need to consider contents, psychometric properties, and applicability when choosing an appropriate needs assessment instrument according to individual purpose and context. Further evaluation or development of needs assessment for the family caregivers of palliative cancer patients is needed, with a particular emphasis on caregivers' perspectives.
