Effects of immersive virtual reality for alleviating anxiety, nausea and vomiting among patients with paediatric cancer receiving their first chemotherapy: protocol for a randomised controlled trial.

INTRODUCTION: Anxiety, nausea and vomiting are common side effects suffered by paediatric patients receiving chemotherapy. Emerging evidence supports the efficacy of immersive virtual reality (IVR) on improving anxiety and distress symptoms including nausea and vomiting in this vulnerable group. This trial aims to evaluate the effects of IVR intervention on anxiety, chemotherapy-induced nausea and vomiting and anticipatory nausea and vomiting in patients with paediatric cancer receiving first chemotherapy. METHOD AND ANALYSIS: An assessor-blinded, randomised controlled trial with a mixed methods evaluation approach. On the basis of our pilot results, 128 chemotherapy-naive patients with paediatric cancer scheduled to receive their first intravenous chemotherapy will be recruited from a public hospital and randomly allocated to intervention (n=64) or control groups (n=64). The intervention group will receive the IVR intervention for three sessions: 2 hours before the first chemotherapy, 5 min before and during their first chemotherapy and 5 min before and during their second chemotherapy, respectively. The control group will receive standard care only. A subsample of 30 participants in the intervention group will be invited for a qualitative interview. Study instruments are: (1) short form of the Chinese version of the State Anxiety Scale for Children, (2) visual analogue scale for anticipatory nausea and vomiting, (3) Chinese version of the Multinational Association of Supportive Care in Cancer Antiemesis Tool and (4) individual face-to-face semistructured interviews to explore intervention participants' perceptions of the IVR intervention. ETHICS AND DISSEMINATION: This study has been approved by the Hong Kong Children's Hospital Research Ethics Committee (HKCH-REC-2021-009). The findings will be disseminated in peer-reviewed journals and through local or interventional conference presentations. TRIAL REGISTRATION NUMBER: ChiCTR2100048732.

Feasibility and acceptability of a culturally-adapted Women's Wellness After Cancer Programme for Chinese women treated for gynaecological cancer: A pilot randomised controlled trial.

Objective: To assess the feasibility and acceptability of a culturally-adapted Women's Wellness After Cancer Programme (WWACPHK) for improving health-related quality of life, anxiety and depressive symptoms and enhancing self-efficacy in engaging in healthy lifestyles among Chinese women treated for gynaecological cancer. Methods: This pilot randomised controlled trial was conducted from May to December 2018. Twenty-six women aged 18 or above who had completed treatment for gynaecological cancer were recruited from a gynaecology outpatient clinic of a public hospital in Hong Kong. They were randomised into intervention (n = 15) or control (n = 11) groups. All data collectors were blinded to the group allocation. Intervention participants were given access to the WWACPHK website and an online discussion forum facilitated by a trained research nurse for 12 weeks, while control participants received standard care. Trial feasibility was assessed by recruitment, consent, and retention rates and website use. Acceptability was explored through semi-structured interviews. Additionally, we trialed the data collection procedure and collected preliminary data on health-related quality of life, anxiety and depressive symptoms, dietary and exercise self-efficacy. Results: Of the 26 participants (Median age = 53.5 years) randomised, three participants dropped out of the study. Recruitment, consent and retention of participants and website use were satisfactory. No posting was made on the discussion forum. The intervention participants (n = 13) exhibited significantly greater improvement than the controls (n = 10) in perceived self-efficacy in adhering to an exercise routine at post-intervention (Cohen's d effect size(d) = 1.06, 95% confidence interval (CI): 0.18, 1.92) and 12-weeks after completion (d = 1.24, 95% CI: 0.32, 2.13). All participants were satisfied with the intervention. Conclusions: The WWACPHK is feasible and acceptable to Chinese women treated for gynaecological cancer and may improve their exercise self-efficacy. A larger-scale study is required to confirm its effects. Trial registrationhttps://www.isrctn.com identifier: ISRCTN12149499.

Cultural Adaptation of the Younger Women's Wellness After Cancer Program for Younger Chinese Women With Breast Cancer: A Pilot Randomized Controlled Trial.

BACKGROUND: The incidence of breast cancer in younger women, that is, aged 50 years or younger, in Hong Kong is increasing. The Internet-based Younger Women's Wellness After Cancer Program (YWWACP) is a whole-lifestyle intervention that can help young women to manage their health and risks of chronic diseases. OBJECTIVES: The study aimed to test the acceptability and feasibility of the culturally adapted YWWACP in Hong Kong (YWWACPHK) and to evaluate its preliminary effects in improving health-related quality of life, distress, sexual function, menopausal symptoms, dietary intake, physical activity, and sleep among younger Chinese women with breast cancer. INTERVENTION/METHODS: Women aged 18 to 50 years with breast cancer were recruited from an oncology outpatient department. The participants in the intervention group received the 12-week YWWACPHK, whereas the control group received standard care. RESULTS: Sixty women consented to participate. At 12 weeks after intervention completion, the intervention group showed a significant increase in the pain subscale scores of sexual function and more improvement in the level of physical activity than the control group, with Hedge g effect sizes 0.66 and 0.65, respectively. Nineteen intervention group participants reported that they were satisfied with the program and suggestions for improvement were provided. CONCLUSION: The implementation of YWWACPHK is feasible. The preliminary findings suggest that YWWACPHK could increase the level of physical activity among the participants. IMPLICATIONS FOR PRACTICE: Nurses could utilize YWWACPHK to support younger Chinese patients with breast cancer to maintain a healthy lifestyle, subject to wider confirmation of these results through a larger study.

Effects of immersive virtual reality for managing anxiety, nausea and vomiting among paediatric cancer patients receiving their first chemotherapy: An exploratory randomised controlled trial.

PURPOSE: To assess the feasibility and acceptability of immersive virtual reality for managing anxiety, nausea and vomiting amongst paediatric patients with cancer receiving their first chemotherapy. METHODS: An exploratory randomised control trial supplemented with qualitative interviews was conducted to enrol Chinese paediatric patients receiving their first intravenous chemotherapy. Participants were randomly assigned to intervention (three immersive virtual reality sessions) or control (standard care) groups. The main outcome measures included (1) feasibility parameters; (2) anxiety, nausea and vomiting; and (3) satisfaction with the chemotherapy procedures. Qualitative data were collected by semi-structured individual interviews with patients, parents and nurses. RESULTS: A total of 19 patients, 19 accompanying parents and 9 nurses were recruited. Results suggested that the intervention was feasible as evidenced by the high consent rate, low withdrawal rate and attrition rate. The intervention group showed significantly better improvement in anxiety at T2 [Hedges' effect size, ES = 1.25, 95% confidence interval (CI): 0.22-2.17)] and T4 [ES = 1.87, 95% CI: 0.72-2.85], as well as greater reduction in acute nausea at T4 [ES = 0.97, 95% CI: 0.02-1.87] than the control group. Qualitative data yielded three categories including positive experiences and perceived benefits of the intervention, and suggested improvements. CONCLUSIONS: This study demonstrated the potential effectiveness, feasibility and acceptability of immersive virtual reality for managing anxiety and acute nausea amongst paediatric patients with cancer receiving their first chemotherapy.

Experiences and perception of character strengths among patients with breast cancer in China: a qualitative study.

OBJECTIVE: To explore the patients' experiences on character strengths that Chinese patients experience after the diagnosis of breast cancer. DESIGN: A qualitative, exploratory study using semistructured interviews based on the patients' lived experience after being diagnosed with breast cancer. Ethics approval was granted. Interviews were audiorecorded and transcribed verbatim. Values in Action Classification of Strengths provided conceptual framework for analysing strengths. Directed content analysis based on the classification of strengths and framework analysis were used to analyse transcribed data. The Standards for Reporting Qualitative Research guideline was followed. SETTING: The Second Affiliated Hospital of Zhengzhou University and Henan Provincial Cancer Hospital in China. PARTICIPANTS: Adult patients over 18 years, diagnosed with breast cancer between October 2019 and December 2020 were recruited. We used purposive sample method to collected data from 24 participants diagnosed with breast cancer. RESULTS: Six themes (virtues) emerged from our analysis. In addition, two new subthemes (character strengths) emerged in this study, selflessness and pragmatism, respectively. Patients with breast cancer described a large repertoire of character strengths they used or wished for during survivorship, including gratitude, hope, humility, kindness, humour, honesty and forgiveness. Cultural values (eg, collectivism, familyism, Confucianism and Buddhist beliefs) helped structure the experiences of Chinese patients' character strengths. Patients wanted their character strengths to be more noticed, appreciated and encouraged by others and reported their psychological trajectory of using personal strengths. CONCLUSION: The findings indicated that patients with breast cancer believing character strengths are important to them. Medical staff should pay more attention to motivating and cultivating character strengths of patients with breast cancer. Attention to make strength-based practices workable in clinical health promotion programmes is necessary. The healthcare system should develop tailored individualised psychological services that specifically address patients' needs for the application of personalised character strengths.

Association between genetic polymorphisms in cytochrome P450 enzymes and survivals in women with breast cancer receiving adjuvant endocrine therapy: a systematic review and meta-analysis.

Tamoxifen is commonly prescribed for preventing recurrence in patients with breast cancer. However, the responses of the patients on tamoxifen treatment are variable. Cytochrome P450 genetic variants have been reported to have a significant impact on the clinical outcomes of tamoxifen treatment but no tangible conclusion can be made up till now. The present review attempts to provide a comprehensive review on the associative relationship between genetic polymorphisms in cytochrome P450 enzymes and survival in breast cancer patients on adjuvant tamoxifen therapy. The literature search was conducted using five databases, resulting in the inclusion of 58 studies in the review. An appraisal of the reporting quality of the included studies was conducted using the assessment tool from the Effective Public Health Practice Project (EPHPP). Meta-analyses were performed on CYP2D6 studies using Review Manager 5.3 software. For other studies, descriptive analyses were performed. The results of meta-analyses demonstrated that shorter overall survival, disease-free survival and relapse-free survival were found in the patients with decreased metabolisers when compared to normal metabolisers. The findings also showed that varying and conflicting results were reported by the included studies. The possible explanations for the variable results are discussed in this review.

Effects of immersive virtual reality for preventing and managing anxiety, nausea and vomiting among paediatric cancer patients receiving their first chemotherapy: A study protocol for an exploratory trial.

BACKGROUND: Anxiety, nausea and vomiting are common side effects suffered by paediatric patients receiving chemotherapy. Emerging evidence supports the efficacy of immersive virtual reality (IVR) on improving anxiety and distress symptoms including nausea and vomiting among this vulnerable group. This trial aims to assess the feasibility and acceptability of IVR for preventing and managing anxiety, nausea and vomiting among paediatric cancer patients receiving their first chemotherapy. METHOD AND ANALYSIS: An exploratory trial supplemented by qualitative methods will be conducted. We will recruit 20 paediatric patients who are aged between 6 and 12 years, chemotherapy naïve, scheduled to receive their first intravenous chemotherapy and able to understand Chinese. Participants will be randomly allocated to intervention or control groups. The intervention group will receive the IVR intervention for three sessions as follows: 4 hours before chemotherapy, 5 minutes before and during their first course chemotherapy and 5 minutes before and during their second course chemotherapy. The control group will receive standard care only. Main outcome measures included (1) key parameters for the design of a definitive trial (i.e. screening, eligibility, consent and withdrawal rates); (2) anxiety, anticipatory and acute chemotherapy-induced nausea and vomiting for collection of preliminary data; (3) feasibility and acceptability of the intervention. Semi-structured interviews will be conducted with patients, parents and oncology nurses. Generalized estimating equations model will be used to compare each of the outcome measures across the time points between the two groups. Qualitative data will be analysed by conventional content analysis. EXPECTED RESULTS: The results of this exploratory trial will inform the design and conduct of future definitive trial.

A practice model of sexuality nursing care: a concept mapping approach.

PURPOSE: The aim of this study is to develop a practice model to enhance the provision of sexuality nursing care for patients with gynaecological cancers. METHODS: A concept mapping approach with three phases was adopted, with phase I involving individual interviews, phase II producing a concept map, and phase III evaluating the applicability of the concept map to clinical practice. A sample of 80 participants, consisting of patients with gynaecological cancers, their spouses/partners, and registered nurses and physicians, was recruited from the gynaecological oncology unit of two acute hospitals in Hong Kong. The participants were involved in all three phases. RESULT: In phase I, 50 statements were generated from the interviews. In phase II, we applied statistical techniques to produce a concept map illustrating the relationships and clustering between the statements. The map depicted seven clusters of statements in descending level of importance: discussion about sexual impact of treatment, organisational support, information-giving, attitude towards sexuality care, personnel involved in sexuality care delivery, timing of sexuality care delivery, and mode of sexuality care delivery. Finally, in phase III, the concept map was used to inform the development of a practice model which is adapted from the extended PLISSIT model. The feedback from participants supported the acceptability and appropriateness of the newly developed practice model to guide the delivery of sexuality care in the local clinical context. CONCLUSION: The newly developed practice model could serve as a reference point for other countries with Chinese populations in matters concerning sexuality care.

Tamoxifen-related endocrine symptoms in Chinese patients with breast cancer: Study protocol clinical trial (SPIRIT Compliant).

BACKGROUND: Breast cancer is the most prevalent cancer in females and disease recurrence remains a significant problem. To prevent recurrence, tamoxifen is prescribed for at least 5 years. However, among patients who receive tamoxifen, individual responses are highly variable. These responses are affected by the type, frequency, and severity of endocrine symptoms, as well as adherence rates. Polymorphisms in genes involved in the metabolism of tamoxifen (ie, CYP3A4, CYP2D6) may influence responses to tamoxifen. In this study, the inter-relationships among endocrine symptoms, drug adherence, and genetic polymorphisms in Chinese breast cancer patients receiving tamoxifen therapy will be examined. We hypothesize that patients with more severe endocrine symptoms will be less likely to adhere to tamoxifen treatment. In addition, we hypothesize that a relationship will exist between the severity of tamoxifen-induced symptoms and allelic variations in tamoxifen metabolism-related genes. Although many association studies have determined that select genotypes influence the efficacy of tamoxifen, very few studies have investigated for associations between tamoxifen-induced endocrine symptoms and these polymorphisms. OBJECTIVES: The aim of this study was to characterize genetic polymorphisms in tamoxifen metabolism-associated genes in Chinese women with breast cancer and to explore the inter-relationships between genetic polymorphisms, endocrine symptoms, and adherence to tamoxifen. METHOD: We will conduct a prospective cohort study that follows 200 Chinese women over 18 months and assess treatment-related symptoms and genetic variations. Endocrine symptoms and drug adherence will be determined through interview-administered standardized questionnaires. Polymorphisms in drug metabolism genes will be determined using real-time polymerase chain reaction based genotyping method. Data will be analyzed to determine associations between allelic variations, endocrine symptoms, and adherence. DISCUSSION: The proposed study will evaluate for polymorphisms in gene(s) that are associated with tamoxifen-related endocrine symptoms and adherence with tamoxifen. We will explore the relationships between genotypes, endocrine symptoms, and drug adherence in Chinese breast cancer patients. Findings from this study may assist clinicians to identify patients at higher risk for a worse symptom experience and lower adherence rates and enable them to initiate appropriate interventions. In the long term, the findings from this study may be used to develop and test tailored symptom management interventions for these patients.

Trimethylamine-N-oxide as One Hypothetical Link for the Relationship between Intestinal Microbiota and Cancer - Where We Are and Where Shall We Go?

Previous epidemiological studies had provided evidence for a link between the microbial dysbiosis and cancer, particularly colorectal cancer (CRC), yet the molecular basis of this link remains elusive. Recently, the association between plasma levels of trimethylamine-N-oxide (TMAO), an oxidised form of trimethylamine (TMA), and risks of various cancers was demonstrated. The discovery could potentially provide an alternative explanation for the aforementioned link, as TMA production is attributed to intestinal bacteria. Current evidence suggests that inflammation could be a potential molecular mechanism to explain the link between TMAO and cancer, although other mechanisms such as oxidative stress, DNA damage and disruption in protein folding might also play a role. This mini-review article first provides an overview of the current evidence for the association between TMAO and certain cancer types, and the potential mechanisms that could explain their association. Thereafter, the direction of further research on the connection between the intestinal microbiota, TMAO and cancer is suggested.

Genomics education in nursing in Hong Kong, Taiwan and Mainland China.

AIM: To identify issues and challenges of genomics education in Hong Kong, Taiwan and Mainland China. BACKGROUND: The use of genetics/genomics in health care, such as genetic testing, pharmacogenomics and tumour profiling in the context of cancer, is increasing. The rapid application of genetics/genomics in clinical practice requires healthcare providers to be competent to practise genetics-related patient care. SOURCES OF EVIDENCE: We reviewed current practices in genomics education in nursing in Hong Kong, Taiwan and Mainland China, including the opportunities for nurses to advance their knowledge and recommendations to incorporate genomics education in the nursing curriculum in these regions. FINDINGS: While many citizens and health professionals recognize the importance of new and exciting research areas of genomics/genetics, there are still many gaps in the translation of genetic/genomic medicine into clinical practice. There is also a similar lack of genetics professionals in China. CONCLUSION: Hong Kong, Taiwan and Mainland China face challenges in promoting genetic education in nursing. A strategic approach in a coordinated effort ineffectively translating genomic knowledge into healthcare practice should be established in these three regions. IMPLICATIONS FOR NURSING AND POLICY: Nursing educators in Hong Kong, Taiwan and Mainland China should link with the international nursing community (e.g. Global Genomics Nursing Alliance) and form closer networks to improve education in the area of genetics and genomics. From a policy level, genomics education is suggested to be incorporated in nursing curriculum to enhance nurses' competency in incorporating genetics/genomics service into patient care.

Regulation of TLR4 in silica-induced inflammation: An underlying mechanism of silicosis.

Silicosis is an incurable lung disease affecting millions of workers in hazardous occupations. It is caused by chronic exposure to the dust that contains free crystalline silica. Silica-induced lung damage occurs by several main mechanisms including cell death by apoptosis, fibrosis and production of cytokines. However, the signal pathways involved in these mechanisms are not fully characterized. In this study, the toll-like receptor 4 (TLR4)-related signal pathway was examined in silica-treated U937-differentiated macrophages. The expression level of TLR4 was measured by both quantitative PCR and Western blot. Confirmation of the involvement of MyD88/TIRAP and NFκB p65 cascade was performed by Western blot. The secretion of cytokines IL-1ß, IL-6, IL-10 and TNFα was measured by enzyme-linked immunosorbent assay. Our results showed that TLR4 and related MyD88/TIRAP pathway was associated with silica-exposure in U937-differentiated macrophages. Protein expression of TLR4, MyD88 and TIRAP was upregulated when the U937-differentiated macrophages were exposed to silica. However, the upregulation was attenuated when TLR4 inhibitor, TAK-242 was present. At different incubation times of silica exposure, it was found that NFκB p65 cascade was activated at 10-60 minutes. Release of cytokines IL-1ß, IL-6, IL-10 and TNFα was induced by silica exposure and the induction of IL-1ß, IL-6 and TNFα was suppressed by the addition of TAK-242. In conclusion, our study demonstrated that TLR4 and related MyD88/TIRAP pathway was involved in silica-induced inflammation in U937-differentiated macrophages. Downstream NFκB p65 cascade was activated within 1 hour when the U937-differentiated macrophages were exposed to silica. The better understanding of early stage of silica-induced inflammatory process may help to develop earlier diagnosis of silicosis.

Sexual function, psychosocial adjustment to illness, and quality of life among Chinese gynaecological cancer survivors.

BACKGROUND: Disrupted sexual function is a prevalent and sustained side effect of gynaecological cancer and its related treatment. This problem may pose challenges to the survivors in the process of illness adjustment, leading to elevated psychological distress and impaired quality of life. However, care and interventions in this area have been neglected in most countries. OBJECTIVES: To investigate sexual function, psychosocial adjustment to illness, and quality of life among Chinese gynaecological cancer survivors in Hong Kong and to explore their associations. METHODS: A cross-sectional design was adopted. Gynaecological cancer survivors were recruited from a gynaecological oncology outpatient clinic at a regional hospital in Hong Kong. RESULTS: A total of 225 Chinese gynaecological cancer survivors were recruited. Their sexual function was found to be impaired. They had satisfactory performance in psychosocial adjustment to illness, but the worst domain was sexual relationships. Their quality of life was fair, with physical and social functioning performing best. Path analysis demonstrated that psychosocial adjustment to illness played a significant mediating role in the relationship between sexual function and quality of life among those who were married or had a regular sex partner. CONCLUSIONS: Impaired sexual function was prevalent among Chinese gynaecological cancer survivors, and psychosocial adjustment to illness mediates the relationship between sexual function and quality of life. In Chinese clinical settings without routine sexuality assessments, early sexual function and psychosocial adjustment assessment should be integrated into routine nursing practice. In addition, a culturally appropriate practice model should be developed to guide sexuality care delivery.

Comparison Study of Uptake of Colorectal Cancer Testing between Ethnic Minorities and the General Population in Hong Kong.

BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers. This study aimed to compare the uptake of CRC testing in the general public and in ethnic minorities in Hong Kong. MATERIALS AND METHODS: This cross-sectional survey covered 2,327 South Asian and Chinese adults aged over 50, recruited from two separate studies. A structured questionnaires were administered by research staff over the telephone or in face- to-face interviews. RESULTS: The uptake rate of CRC testing among South Asians was significantly lower than that of the general population in Hong Kong. Factors associated with the uptake rate were health professional's recommendation, perception of regular visits to doctor, use of complementary therapy, ethnicity, perceived susceptibility to cancer, presence of chronic illness, and education level. In addition, a significant interaction (p<0.05) between ethnicity and health professionals' recommendations was found, after adjustment for the main independent factors identified. CONCLUSIONS: Older people with lower educational attainment, without chronic illness and those have lower perceived susceptibility to cancer may be targeted for CRC testing promotion in the society. In addition, health professionals can play a highly influential role in promoting such testing, particularly among ethnic minorities.
