RESUMO
Current treatment outcome of patients with glioblastoma (GBM) remains poor. Following standard therapy, recurrence is universal with limited survival. Tumors from 173 GBM patients are analysed for somatic mutations to generate a personalized peptide vaccine targeting tumor-specific neoantigens. All patients were treated within the scope of an individual healing attempt. Among all vaccinated patients, including 70 treated prior to progression (primary) and 103 treated after progression (recurrent), the median overall survival from first diagnosis is 31.9 months (95% CI: 25.0-36.5). Adverse events are infrequent and are predominantly grade 1 or 2. A vaccine-induced immune response to at least one of the vaccinated peptides is detected in blood samples of 87 of 97 (90%) monitored patients. Vaccine-specific T-cell responses are durable in most patients. Significantly prolonged survival is observed for patients with multiple vaccine-induced T-cell responses (53 months) compared to those with no/low induced responses (27 months; P = 0.03). Altogether, our results highlight that the application of personalized neoantigen-targeting peptide vaccine is feasible and represents a promising potential treatment option for GBM patients.

BACKGROUND: Interventions to foster resilience may promote mental health recovery after exposure to stressors. However, comprehensive systematic syntheses of such evidence in family members of pediatric cancer patients are lacking. OBJECTIVE: To systematically review and meta-analyze the evidence for the effects of psychological interventions at fostering resilience in family members of pediatric cancer patients. METHODS: PubMed, Cumulative Index to Nursing and Allied Health Literature, and 9 other databases were searched for articles published until March 2023. Empirical studies on psychological interventions to improve resilience in family members of pediatric cancer patients were included. Full-text and quality appraisals were performed independently by 2 reviewers. Pooled effect sizes were calculated using random-effects meta-analyses. RESULTS: Seventeen studies were included, of which 10 were included in the meta-analyses. There was a positive effect of interventions on resilience at postintervention time points, but no effects on depressive symptoms, stress, or well-being. The improvement in resilience was sustained in the short term (≤3 months) and medium term (>3 to ≤6 months), with delayed effects on depressive symptoms and stress. In the 6 studies that reported moderate effect sizes, the interventions comprised problem-solving skills, cognitive strategies, promotion of personal strength, and social resources. CONCLUSION: The findings indicated that psychological interventions targeting resilience have the potential to positively affect the resilience and mental health outcomes of family members, particularly parents. IMPLICATIONS FOR PRACTICE: Psychological interventions targeting resilience hold promise in improving the mental health of family members. Future interventions should clearly specify the characteristics of the intervention, such as mode of delivery, format, and duration.
RESUMO
BACKGROUND AND AIMS: Despite evidence that patients living with cancer who continue to smoke after diagnosis are at higher risk for all-cause mortality and reduced treatment efficacy, many cancer patients continue to smoke. This protocol is for a study to test the effectiveness of a self-determination theory-based intervention (quit immediately or progressively) plus instant messaging (WhatsApp or WeChat) to help smokers with cancer to quit smoking. DESIGN: This will be a multi-centre, two-arm (1:1), single-blind, pragmatic, individually randomized controlled trial. SETTING: Taking part will be specialist outpatient clinics in five major hospitals in different location-based clusters in Hong Kong. PARTICIPANTS: The sample will include 1448 Chinese smokers living with cancer attending medical follow-ups at outpatient clinics. INTERVENTIONS: The intervention group will receive brief advice (approximately 5-8 minutes) from research nurses in the outpatient clinics and then be invited to choose their own quit schedules (immediate or progressive). During the first 6-month follow-up period they will receive instant messaging with smoking cessation advice once per week for the first 3 months, and thereafter approximately once per month. They will also receive four videos, and those opting to quit progressively will receive a smoking reduction leaflet. The control group will also receive brief advice but be advised to quit immediately, and instant messaging with general health advice during the first 6-month follow-up period using the same schedule as the intervention group. Participants in both groups will receive smoking cessation leaflets. MEASUREMENTS: The primary outcome is biochemically validated smoking abstinence at 6 months, as confirmed by saliva cotinine level and carbon monoxide level in expired air. Secondary outcomes include biochemically validated smoking abstinence at 12 months, self-reported 7-day point prevalence of smoking abstinence at 6 and 12 months, self-reported ≥ 50% reduction of cigarette consumption at 6 and 12 months and quality of life at 6 and 12 months. All time-points for outcomes measures are set after randomization. COMMENTS: The results could inform research, policymaking and health-care professionals regarding smoking cessation for patients living with cancer, and therefore have important implications for clinical practice and health enhancement.

BACKGROUND: While text messaging has proven effective for smoking cessation (SC), engagement in the intervention remains suboptimal. OBJECTIVE: This study aims to evaluate whether using more interactive and adaptive instant messaging (IM) apps on smartphones, which enable personalization and chatting with SC advisors, can enhance SC outcomes beyond the provision of brief SC advice and active referral (AR) to SC services. METHODS: From December 2018 to November 2019, we proactively recruited 700 adult Chinese daily cigarette users in Hong Kong. Participants were randomized in a 1:1 ratio. At baseline, all participants received face-to-face brief advice on SC. Additionally, they were introduced to local SC services and assisted in selecting one. The intervention group received an additional 26 personalized regular messages and access to interactive chatting through IM apps for 3 months. The regular messages aimed to enhance self-efficacy, social support, and behavioral capacity for quitting, as well as to clarify outcome expectations related to cessation. We developed 3 sets of messages tailored to the planned quit date (within 30 days, 60 days, and undecided). Participants in the intervention group could initiate chatting with SC advisors on IM themselves or through prompts from regular messages or proactive inquiries from SC advisors. The control group received 26 SMS text messages focusing on general health. The primary outcomes were smoking abstinence validated by carbon monoxide levels of <4 parts per million at 6 and 12 months after the start of the intervention. RESULTS: Of the participants, 505/700 (72.1%) were male, and 450/648 (69.4%) were aged 40 or above. Planning to quit within 30 days was reported by 500/648 (77.2%) participants, with fewer intervention group members (124/332, 37.3%) reporting previous quit attempts compared with the control group (152/335, 45.4%; P=.04). At the 6- and 12-month follow-ups (with retention rates of 456/700, 65.1%, and 446/700, 63.7%, respectively), validated abstinence rates were comparable between the intervention (14/350, 4.0%, and 19/350, 5.4%) and control (11/350, 3.1% and 21/350, 6.0%) groups. Compared with the control group, the intervention group reported greater utilization of SC services at 12 months (RR 1.26, 95% CI 1.01-1.56). Within the intervention group, engaging in chat sessions with SC advisors predicted better validated abstinence at 6 months (RR 3.29, 95% CI 1.13-9.63) and any use of SC services (RR 1.66, 95% CI 1.14-2.43 at 6 months; RR 1.67, 95% CI 1.26-2.23 at 12 months). CONCLUSIONS: An IM-based intervention, providing support and assistance alongside brief SC advice and AR, did not yield further increases in quitting rates but did encourage the utilization of SC services. Future research could explore whether enhanced SC service utilization leads to improved long-term SC outcomes.

BACKGROUND: Studies have shown that caregivers of children with cancer experience challenges when caring for their children. To date, no studies have examined the experience of caregivers of children with cancer in Malawi, a low-income country in sub-Saharan Africa. Hence, this study aimed to explore the experiences of caregivers of Malawian children receiving cancer treatment. METHODS: This explorative qualitative study used semi-structured interviews to collect data from 22 caregivers of children receiving cancer treatment. The data were analysed using qualitative content analysis. RESULTS: Five themes emerged from the QCA. The caregivers perceived their children's cancer as a burden, a form of psychological torture and a disruptor of family routines and social lifestyles. They also reported self-isolation due to the stigma that they faced in the course of caring for their children and a need for informational, psychosocial, spiritual and financial support. CONCLUSION: Caregivers of Malawian children with cancer experience physical and psychosocial challenges as they are caring for their children with cancer. Developing appropriate interventions would enable nurses to offer optimal support to these caregivers in dealing with these challenges and meeting their needs effectively.

BACKGROUND: Limited treatment options exist for refractory Rhinitis Medicamentosa (RM). The role of surgery after failed medical management is not well defined. Mucosal contact points and restricted airflow often perpetuate decongestant use. This study assessed the long-term outcomes of nasal surgery in patients with refractory RM. METHODS: A prospective cohort study of refractory RM treated with nasal surgery was performed with ≥12 months follow-up. Refractory RM was defined as nasal decongestant use once per day continuously for ≥4 weeks despite medical therapy. Patients with concomitant sinus disease and nonrhinitis conditions were excluded. Sinonasal Outcome Test (SNOT22), Nasal Symptom Score (NSS), and nasal medication use were assessed. Patients who ceased decongestants were compared with ongoing users. RESULTS: A total of 56 patients (age 48.4 [5.0] years, 50% female) were assessed. Median follow-up was 3.4(1.6-6.2) years. Total cessation of decongestants was achieved in 91.1%, while 5.4% had intermittent use, and 3.6% reported daily use. Ongoing users had higher odds of concomitant asthma (40.0% vs. 3.9%; odds ratio [OR], 16.33 [1.7-159.75]; p = 0.036), reduced symptom improvement (ΔSNOT22, -4.6 [15.7] vs. 27.1 [17], p = 0.009 and ΔNSS, -1.0 [4.2] vs. -6.6 [5.1], p = 0.025), and greater ongoing use of nasal corticosteroid (60.0% vs. 5.9%; OR 24.0 [2.8-203.1]) and saline sprays (40% vs. 3.9%; OR 16.3 [1.7-159.8]) but showed no difference in allergy status (OR, 0.7[0.1-7.1]), previous surgery (OR, 1.0[0.1-10.2]), gastroesophageal reflux (OR 1.0[0.1-10.2], or underlying anxiety/depression (OR 6.1[0.8-45.9]) compared with those who ceased. CONCLUSION: Surgically re-establishing a nasal airway was associated with long-term decongestant cessation and symptom improvement in medically refractory RM.

INTRODUCTION: Exposure of pregnant women and newborns to secondhand smoke (SHS) can lead to adverse maternal and neonatal health outcomes. Among expectant and new fathers, who are the main source of SHS exposure for pregnant women, new mothers and babies, smoking rates remain high. A partner's pregnancy potentially constitutes a critical period where expectant and new fathers are motivated to quit smoking. However, there is no consensus on the optimal form and delivery of smoking cessation and relapse-prevention interventions. We present a systematic review and network meta-analysis protocol that aims to synthesise and evaluate the effectiveness of smoking cessation and relapse-prevention interventions tailored for this population. METHODS AND ANALYSIS: To identify relevant studies, we will conduct a comprehensive search, in English and Chinese, of 10 electronic databases. The review will include randomised and quasi-randomised controlled trials that compare behavioural interventions (tailored and non-tailored) with/without the addition of pharmacotherapy with usual care, a minimal or placebo control for assisting expectant and new fathers to quit smoking and prevent smoking relapse. The primary outcome of interest is the self-reported and/or biochemically verified smoking abstinence at ≥1-month follow-up. Two reviewers will independently screen, select and extract relevant studies, and perform a quality assessment. Disagreements will be resolved by a consensus or third-party adjudication. The Cochrane Risk of Bias tool V.2 will be used to assess the risk of bias in the included studies. We will obtain the results of the systematic review through pooled quantitative analyses using a network meta-analysis. Sensitivity and subgroup analyses will be performed. ETHICS AND DISSEMINATION: Ethical approval is not required for this systematic review of published data. The findings will be disseminated via peer-reviewed publication. PROSPERO REGISTRATION NUMBER: CRD42022340617.

PURPOSE: Psychoeducation interventions (PEIs) have been used as an adjunct treatment for negative psychological outcomes in caregivers of children with cancer. This systematic review and meta-analysis aimed to evaluate the evidence on the effectiveness of PEIs in reducing anxiety and depressive symptoms and improving health-related quality of life (HRQoL) and coping skills in caregivers of children with cancer. METHOD: Ten English databases were searched to identify studies on PEIs for caregivers of children with cancer. Studies inclusion criteria were as follows: (1) participants who were caregivers of children with cancer receiving treatment; (2) psychoeducational interventions assessing anxiety, depressive symptoms, HRQoL, and coping outcomes; and (3) usual care, waitlist, or active control as a control group. Meta-analysis and narrative synthesis were used to analyse data. RESULTS: Fourteen randomised control trials were included. PEIs have a beneficial effect on anxiety levels (SMD: -0.59, 95% CI [-0.92, -0.25], p = 0.0007), quality of life (SMD: -0.31, 95% CI [-0.00, -0.61], p = 0.05) and depressive symptoms (SMD: -1.18, 95% CI [-2.08, -0.28], p = 0.01) immediately post-intervention. The effect of PEIs was maintained at long-term follow-up on depressive symptoms (SMD: -0.52, 95% CI [-1.54, -0.36], p = 0.0004). Similarly, the synthesised data suggest that PEIs are effective in improving coping skills. CONCLUSION: The review provides evidence that PEIs effectively reduce negative psychological outcomes and improve coping skills in caregivers of children with cancer. However, due to methodological flaws and heterogeneity of the interventions evaluated, more research is needed to determine the most effective PEI design and improve the quality of evidence.
RESUMO
PURPOSE: Studies from different countries show that caregivers of children with haematological cancer receiving chemotherapy encounter substantial distress when witnessing their children's suffering from the illness and chemotherapy side effects, alongside experiencing psychosocial problems and financial difficulties. However, no studies for this are available from Ethiopia in its specific cultural background and health care system. Thus, this study aimed to explore and bring into light the experiences of Ethiopian family caregivers of children with haematological malignancies receiving chemotherapy. METHODS: A qualitative descriptive study was conducted using a maximum variation purposive sampling method among 20 caregivers. Semi-structured in-depth face-to-face interviews were conducted until no new themes discovered. The data were analysed through qualitative thematic analysis. RESULTS: Participants believed cancer comes from different reasons and chemotherapy is ineffective in curing cancer. They identified various chemotherapy-related side effects, and psychosocial problems. The lack of health insurance, loss of job or income, and high cost of treatments were the major financial challenges. Adhering to treatments, acceptance and reassurance, religious and spiritual therapies, traditional medicine, and a support system were the major coping strategies. They had needs for improved support in information and education, psychosocial support, and in the availability of medications. CONCLUSIONS: Systematic health assessment, provision of targeted information and education, psychosocial support, nursing care respecting the caregivers' positive coping strategies, improvement in chemotherapy medication availability, and facilitating connections with supporting organisations would help improve child outcomes and address caregiver needs.
RESUMO
Acute and chronic wounds involving deeper layers of the skin are often not adequately healed by dressings alone and require therapies such as skin grafting, skin substitutes, or growth factors. Here we report the development of an autologous heterogeneous skin construct (AHSC) that aids wound closure. AHSC is manufactured from a piece of healthy full-thickness skin. The manufacturing process creates multicellular segments, which contain endogenous skin cell populations present within hair follicles. These segments are physically optimized for engraftment within the wound bed. The ability of AHSC to facilitate closure of full thickness wounds of the skin was evaluated in a swine model and clinically in 4 patients with wounds of different etiologies. Transcriptional analysis demonstrated high concordance of gene expression between AHSC and native tissues for extracellular matrix and stem cell gene expression panels. Swine wounds demonstrated complete wound epithelialization and mature stable skin by 4 months, with hair follicle development in AHSC-treated wounds evident by 15 weeks. Biomechanical, histomorphological, and compositional analysis of the resultant swine and human skin wound biopsies demonstrated the presence of epidermal and dermal architecture with follicular and glandular structures that are similar to native skin. These data suggest that treatment with AHSC can facilitate wound closure.

Evidence shows that resilience is crucial to maintain psychological well-being and quality of life in the face of stress and adversity. However, the relationships between resilience and psychological well-being and factors associated with quality of life in Hong Kong Chinese parents of children with cancer are underexplored. This study aimed to examine the interrelationships among resilience, ways of coping, psychological well-being, and quality of life among Chinese parents of children with cancer, and identify factors associated with their quality of life. A cross-sectional study was conducted with 119 Chinese parents of children with cancer at the Hong Kong Children's Hospital between January 2020 and March 2022. Parents' resilience level, ways of coping, depressive symptoms, state anxiety scores, perceived social support, and quality of life were assessed. Participating parents (n = 119) included 98 mothers (82.4%) and 11 parents were from single-parent families (9.2%). Almost half (47.9%) of the parents were potentially at risk for depression. The results showed that participants from single-parent families reported statistically significantly lower levels of resilience (p < 0.001), more depressive symptoms (p < 0.001), and poorer quality of life (p < 0.001) than those who lived with their partners (married). In addition, parents who adopted problem-focused coping strategies reported statistically significantly higher levels of resilience (p < 0.001), fewer depressive symptoms (p < 0.001), and better quality of life (p < 0.001) than those who adopted emotion-focused coping strategies. A multiple regression analysis revealed that resilience (p < 0.001) was associated with quality of life among parents of children with cancer. This study provides further support that resilience is an important factor associated with quality of life in parents of children with cancer. Assessing resilience in parents is an important prerequisite for designing appropriate interventions to increase their resilience and enhance their quality of life.

Twenty-four dogs with OS underwent limb amputation. Serum, OS tumour, and normal bone were harvested at time of surgery. RNA was extracted and gene expression was performed using quantitative polymerase chain reaction (qPCR). Tissue and blood copper concentrations were also determined with spectrophotometry. Compared to bone, tumour samples had significantly higher expressions of antioxidant 1 copper chaperone (ATOX1, p = .0003). OS tumour copper levels were significantly higher than that of serum (p < .010) and bone (p = .038). Similar to our previous observations in mouse and human OS, dog OS demonstrates overexpression of genes that regulate copper metabolism (ATOX1), and subsequent copper levels. Dogs with OS may provide a robust comparative oncology platform for the further study of these factors, as well as potential pharmacologic interventions.

Continued smoking among patients with chronic diseases detrimentally affects their health and treatment outcomes. However, a majority of smokers with chronic diseases appear to have no intention to quit. Understanding the needs and concerns of this population is a crucial step in facilitating the design of an appropriate smoking cessation intervention. This study aimed to understand the risk perception, behaviours, attitudes, and experiences related to smoking and smoking cessation among patients with chronic diseases, including cardiovascular diseases, chronic respiratory diseases, and/or diabetes in Hong Kong. Individual semi-structured interviews with smokers with chronic diseases (n = 30) were conducted from May to July 2021. The methods and results are reported according to the COREQ. Four themes were generated: (1) perceptions of the association between chronic diseases and smoking/smoking cessation; (2) perceptions of the health/disease status; (3) quitting smoking is not the first priority; and (4) perceived barriers to quitting smoking. This study addressed a gap in the literature by gathering data concerning the perspectives of smokers with chronic diseases on smoking and smoking cessation. The deficit of knowledge among smokers with chronic diseases warrants the reinforcement of health education targeting this population. Our findings indicate the need for further efforts in designing appropriate smoking cessation interventions targeting smokers with chronic diseases, which will match the needs and concerns identified in this study.

BACKGROUND: Nausea and vomiting are distressing symptoms reported by pediatric oncology patients during cancer treatment. More than 40% of them experience these symptoms even after receiving antiemetics. OBJECTIVE: Given the limitations of pharmacological interventions, this systematic review synthesized the evidence for the effectiveness of complementary and alternative medicine in controlling nausea and vomiting among pediatric oncology patients. METHODS: Ten databases were searched to identify relevant randomized controlled trials. The risk of bias of selected studies was graded using the Cochrane risk-of-bias tool for randomized trials. The primary outcomes were nausea and vomiting. The secondary outcomes were intervention adherence and number of adverse events. RESULTS: Nineteen papers met the inclusion criteria and were included in the review. Sixteen studies showed high risk of bias. The tested interventions were acupuncture, acupressure, aromatherapy, hypnosis, massage, active cognitive distraction/relaxation techniques, creative arts therapy, psychoeducation, and combined massage and acupressure. Acupuncture, hypnosis, and massage interventions improved nausea and vomiting. Fifteen trials reported intervention adherence; only 7 monitored adverse events. The most common reason for dropout was refusal from patients and/or their guardians. A total of 34 adverse events were noted. CONCLUSIONS: There is insufficient evidence that complementary and alternative medicine is effective, feasible, or safe in controlling nausea and vomiting among pediatric oncology patients due to high risk of bias. IMPLICATIONS FOR PRACTICE: Acupuncture, hypnosis, and massage appear to have therapeutic benefits. However, more robust studies are needed to address the identified methodological issues and determine the real value of these 3 interventions.
RESUMO
Soft tissue sarcomas (STS) are rare malignant tumors often associated with poor outcomes and high local recurrence rates. Current tools for intraoperative and definitive margin assessment include intraoperative frozen section and permanent pathology, respectively. Indocyanine green dye (ICG) is a historically safe fluorophore dye that has demonstrated efficacy for intraoperative margin assessment in the surgical management of both breast and gastrointestinal cancers. The utility of ICG in the surgical management of sarcoma surgery has primarily been studied in pre-clinical mouse models and warrants further investigation as a potential adjunct to achieving negative margins. This study is a prospective, non-randomized clinical study conducted on patients with confirmed or suspected STS. Patients younger than 18 years, with a prior adverse reaction to iodine or fluorescein, or with renal disease were excluded from the study. Intravenous ICG was infused approximately three hours prior to surgery at a dosage of 2.0-2.5 mg/kg, and following tumor resection, the excised tumor and tumor bed were imaged for fluorescence intensity. When scanning the tumor bed, a threshold of 77% calibrated to the region of maximum intensity in the resected tumor was defined as a positive ICG margin, according to published protocols from the breast cancer literature. ICG results were then compared with the surgeon's clinical impression of margin status and permanent pathology results. Out of 26 subjects recruited for the original study, 18 soft tissue sarcomas (STS) were included for analysis. Three subjects were excluded for having bone sarcomas, and five subjects were excluded due to final pathology, which was ultimately inconsistent with sarcoma. The average age of patients was 64.1 years old (range: 28-83), with an average ICG dose of 201.8 mg. In 56% (10/18) of patients, ICG margins were consistent with the permanent pathology margins, with 89% specificity. The use of ICG as an intraoperative adjunct to obtaining negative margins in soft tissue sarcoma surgery is promising. However, studies with larger sample sizes are warranted to further delineate the accuracy, optimal dosage, timing, and types of sarcoma in which this diagnostic tool may be most useful.
RESUMO
This study analyzed archived data from a previous large-scale survey study on multiple health-risk behaviors among Chinese adults in Hong Kong between 21 June and 31 August 2021. In addition, this study examined participants' perceptions of the risks associated with their behaviors, their attitudes toward adopting healthy behaviors, and the impact of COVID-19 on their health-risk behaviors. A total of 4605 participants who had at least one health-risk behavior were included in the analysis. The results showed that about half of the participants were unaware that non-communicable diseases (NCDs) can be caused by health-risk behaviors such as tobacco use, harmful use of alcohol, physical inactivity, and an unhealthy diet. More than half of the participants did not have regular body checkups or monitor their physical health at home. Many participants paid more attention to their health due to the COVID-19 pandemic, but few made changes to their unhealthy habits or adopted a healthier lifestyle. Of the 704 smokers, 60.9% did not realize that smoking increases the risk of transmitting COVID-19 to others. Only 32.2% and 11.9% smokers had the intention to quit smoking and reduced their cigarette consumption, respectively. Additionally, 13.6% reported that their daily cigarette consumption had increased, and 78.8% changed their smoking behavior during the pandemic. Healthcare professionals must educate the public about the association between health-risk behaviors and NCDs and between COVID-19 and NCDs. The government should formulate a long-term plan to strengthen the primary healthcare system and address the challenges posed by the rising prevalence of NCDs.

BACKGROUND: A progressive approach to quitting smoking has been a popular strategy for motivating smokers who are reluctant to quit. However, whether this strategy can effectively achieve complete cessation or is as successful as quitting immediately remains unresolved. This study aimed to determine whether quitting immediately or progressively was more effective in achieving complete cessation among smokers in Hong Kong who presented at emergency departments. METHODS AND FINDINGS: A posteriori analysis of a single-blinded, multicenter, randomized controlled trial was performed. The original trials was conducted at emergency departments of four major acute hospitals in different districts of Hong Kong. In total, 1571 smokers 18 years or older who presented at 4 major emergency departments between July 4, 2015 and March 17, 2017 were randomized into an intervention group (n = 787) and a control group (n = 784). The intervention group received brief advice (about 1 minute) and could choose their own quit schedules (immediate or progressive, labeled QI and QP, respectively). The control group received a smoking cessation leaflet. Follow-ups were conducted at 1, 3, 6 and 12 months. The primary outcomes, by intention-to-treat, were biochemically validated abstinence between the QI subgroup and control group; between the QP subgroup and control group, and between the QI subgroup and QP subgroup at 6 months. After the propensity sore matching, the biochemically validated abstinence was statistically significantly higher in the QI subgroup than the control group at 6 months (12.1% vs 3.4%, P = 0.003; adjusted odds ratio [aOR] 4.34, 95% CI 1.63-11.52) and higher in the QP subgroup than the control group at 6 months (9.8% vs 3.4%, P = 0.02; aORs 2.95, 95% CI: 1.04-8.39). No statistically significant differences of biochemically validated abstinence at both 6 month (12.1% vs 9.8%, P = 0.49; aORs 1.50, 95% CI: 0.71-3.19) were found in the comparison between QI and QP subgroups. CONCLUSIONS: This study demonstrates that the strategy of quitting progressively is effective, especially for smokers who lack motivation or find it difficult to quit. If adopted routinely, such an approach can help achieve a greater level of smoking abstinence in the community. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02660957.

BACKGROUND: Childhood cancer negatively impacts a child's physical, mental, and behavioural health and significantly affects their health-related quality of life. The Pediatric Quality of Life Inventory 4.0 Generic Core Scale (PedsQL™ 4.0 GCS) is one of the most commonly used measures of the quality of life in children. However, the Amharic version of PedsQL™ 4.0 GCS has not been validated in a paediatric oncology population. This study aimed to translate and evaluate the psychometric properties of the Amharic PedsQL™ 4.0 GCS (PedsQL™ 4.0 GCS (A)) for Ethiopian children with cancer. METHODS: A descriptive cross-sectional study was conducted among children aged 8-18 years with any type of cancer across the cancer trajectory. Cronbach's alpha and intraclass correlation coefficient were computed to determine the internal consistency and test-retest reliability of the scale. The convergent validity was established by examining the correlation of the PedsQL™ 4.0 GCS (A) with the Amharic version of the Revised Child Anxiety and Depression Scale (RCADS-25(A)). Factorial validity was evaluated by conducting a confirmatory factor analysis. RESULTS: The study included 142 participants with childhood cancer. PedsQL™ 4.0 GCS (A) had good validity and reliability. It demonstrated high internal consistency with a Cronbach's alpha of 0.96 for the scale and 0.82-0.95 for the subscales. The intraclass correlation coefficient for the scale was 0.9 and that for the subscales was 0.76-0.90. The PedsQL™ 4.0 GCS (A) was highly correlated with RCADS-25 (A) (r = - 0.97, p < 0.001), supporting its convergent validity. The four-factor structure of the model fitted the data satisfactorily (χ2/df = 1.28; CFI = 0.97; TLI = 0.97; RMSEA = 0.05; SRMR = 0.05), supporting the factorial validity of the PedsQL™ 4.0 GCS (A). CONCLUSION: The PedsQL™ 4.0 GCS (A) demonstrates desirable psychometric properties for assessing quality of life among Ethiopian children with cancer. The scale can be used in clinical settings for assessing and evaluating quality of life in children with cancer. The use of parent-report versions and studies in those with different health conditions and healthy populations are necessary to further establish the psychometric properties of the PedsQL™ 4.0 GCS (A).
