RESUMO

BACKGROUND: Cancer screening is a pivotal method for reducing mortality from disease, but the screening coverage is still lower than expected. Telehealth interventions demonstrated significant benefits in cancer care, yet there is currently no consensus on their impact on facilitating cancer screening or on the most effective remote technology. DESIGN: A network meta-analysis was conducted to detect the impact of telehealth interventions on cancer screening and to identify the most effective teletechnologies. METHODS: Six English databases were searched from inception until July 2023 to yield relevant randomized controlled trials (RCTs). Two individual authors completed the literature selection, data extraction, and methodological evaluations using the Cochrane Risk of Bias tool. Traditional pairwise analysis and network meta-analysis were performed to identify the overall effects and compare different teletechnologies. RESULTS: Thirty-four eligible RCTs involving 131,644 participants were enrolled. Overall, telehealth interventions showed statistically significant effects on the improvement of cancer screening. Subgroup analyses revealed that telehealth interventions were most effective for breast and cervical cancer screening, and rural populations also experienced benefits, but there was no improvement in screening for older adults. The network meta-analysis indicated that mobile applications, video plus telephone, and text message plus telephone were associated with more obvious improvements in screening than other teletechnologies. CONCLUSION: Our study identified that telehealth interventions were effective for the completion of cancer screening and clarified the exact impact of telehealth on different cancer types, ages, and rural populations. Mobile applications, video plus telephone, and text message plus telephone are the three forms of teletechnologies most likely to improve cancer screening. More well-designed RCTs involving direct comparisons of different teletechnologies are needed in the future. CLINICAL RELEVANCE: Telehealth interventions should be encouraged to facilitate cancer screening, and the selection of the optimal teletechnology based on the characteristics of the population is also necessary.

RESUMO

AIMS AND OBJECTIVES: To assess the effectiveness of different nonpharmacological treatments for severe radiation-induced oral mucositis in patients with head and neck cancer. BACKGROUND: Radiation-induced oral mucositis is highly prevalent in patients with head and neck cancer. Current medications for radiation-induced oral mucositis are limited in effectiveness and susceptible to side effects, and while there is an increasing adoption of nonpharmacological interventions, the optimal one remains unclear. DESIGN: Systematic review and network meta-analysis based on the PRISMA-NMA guidelines. METHODS: Six databases were searched. Two authors independently performed the literature screening, data extraction and methodological quality assessment of the included studies. Traditional pairwise meta-analysis was performed by R Studio. A network meta-analysis was then conducted to assess the effects of nonpharmacological interventions for severe radiation-induced oral mucositis in patients with head and neck cancer. RESULTS: Fifty-two studies involving seven types of nonpharmacological interventions were enrolled. The network meta-analysis indicated that natural plant-based therapies might be the most effective, health education interventions might be the second most effective, and honey might be the third most effective interventions for reducing the incidence of severe radiation-induced oral mucositis. For reducing the incidence of severe oral mucositis-related pain, the pairwise meta-analysis showed that only natural plant-based therapies and health education interventions were effective. CONCLUSIONS: Nonpharmacological interventions are effective in the management of severe radiation-induced oral mucositis among patients with head and neck cancer. RELEVANCE TO CLINICAL PRACTICE: Nonpharmacological interventions are a category of safe and effective adjunctive therapies that should be encouraged in clinical practice. TRIAL REGISTRATION DETAILS: CRD42023400745.

RESUMO

PURPOSE: To identify factors influencing the quality of life of family caregivers with terminal cancer in Chinese palliative wards and to test whether social support mediates the relationship between caregiver burden and caregiver quality of life. METHODS: A cross-sectional study design was used. Sociodemographic data were collected and the Quality of Life Scale, the Caregiver Burden Scale, and the Social Support Rating Scale were administered to Chinese family caregivers from December 2021 to December 2022. The factors influencing quality of life and caregiver burden were examined using the Mann‒Whitney U test and the Kruskal‒Wallis H test. The mediating role of social support was assessed using the bootstrap method. RESULTS: Family caregivers' quality of life in Chinese terminal cancer palliative units was related to caregivers' daily care time, the caregiver-patient relationship, and patient age. Caregiver quality of life was negatively associated with caregiver burden and positively associated with social support. In addition, social support mediated the relationship between caregiver burden and caregiver quality of life. CONCLUSION: Social support mediated the impact of caregiver burden on caregiver quality of life. Family, society, and palliative care institutions should be integrated to take actions to reduce family caregiver burden, increase social support, and transfer the positive aspects of specific cultural contexts to the culture of palliative care in general to collaboratively cope with various problems related to end-stage cancer.

RESUMO

BACKGROUND: Timely and proper suppression of inflammation can effectively reduce myocardial injury and promote the postmyocardial infarction (post-MI) wound-healing process. We have previously found that cardiac conduction regulatory RNA (CCRR), a long noncoding RNA (lncRNA) transcribed by the gene located on chromosome 9, with abundant expression in the heart, elicits antiarrhythmic effects in heart failure, and this is a continuing study on the role of CCRR in MI. METHODS: CCRR was overexpressed in CCRR transgenic mice or after injection of adeno-associated virus-9 (AAV-9). MI surgery was performed, and cardiac function was assessed in vivo by echocardiography, followed by histologic analyses. Western blot analysis and qRT-PCR were performed to investigate the effects of CCRR on macrophages, cardiomyocytes, and cardiomyocytes cocultured with macrophages. Through microarray analysis and RNA-binding protein immunoprecipitation (RIP) and other related techniques were also employed to study the effects of CCRR on Toll-like receptor (TLR)2 and TLR4. RESULTS: We found that CCRR level was significantly decreased with increases in proinflammatory cytokines and activation of the TLR signalling pathway in the heart of the 3-day MI mice. CCRR overexpression downregulated TLR2 and TLR4 in MI and effectively inhibited the inflammatory responses in primary cardiomyocytes and macrophages cultured under hypoxic conditions. Downregulation of CCRR induced excessive inflammatory responses by activating the TLR signalling pathway. CCRR acted by suppressing TLR2 and TLR4 to inhibit the secretion of proinflammatory factors to reduce infarct size, thereby improving cardiac function. CONCLUSIONS: CCRR protected cardiomyocytes against MI injury by suppressing inflammatory response through targeting the TLR signalling pathway.

RESUMO

BACKGROUND: With the development of spinal endoscopic techniques, on the basis of our previous experience in treating various types of cervical disc herniation with this endoscopic technique, we took the lead in applying the percutaneous fully endoscopic anterior transcorporeal procedure to be utilized in the treatment of the isolated cervical ossification of the posterior longitudinal ligament (OPLL). CASE PRESENTATION: A 66-year-old male patient who weighed 57 kg, with a height of 169 cm was admitted to the hospital on September 16, 2021 because of recurrent pain and numbness in the neck, shoulder, and right arm for 2 years, which as aggravated for the last 2 weeks. Two years ago, the patient developed neck and shoulder pain accompanied by right arm pain without obvious predisposing factors, and numbness in the first web space of the right hand. In the last 2 weeks, he had difficulty moving the right arm, but no pain or numbness in the contralateral arm. MRI and CT scans demonstrated that the ossified posterior longitudinal ligament of the cervical 5/6 vertebrae with spinal canal stenosis and seriously compressed the spinal cord patient was treated with a percutaneous fully endoscopic anterior transcorporeal procedure. CONCLUSION: Our percutaneous fully endoscopic anterior transcorporeal procedure is a feasible, minimally invasive surgery for treating isolated ossification of the posterior longitudinal ligament in the cervical spine.

RESUMO

PURPOSE: To investigate the symptom clusters of Chinese patients with lung cancer, and explore their impact on quality of life (QoL) and each of its functioning. METHOD: A cross-sectional study was conducted between October 2022 and April 2023 among 219 lung cancer patients at a general hospital in Sichuan Province. Data were collected using a general information questionnaire, the MD Anderson Symptom Inventory, and the EORTC QLQ-C30. R within the RStudio platform was used to conduct descriptive statistics, exploratory factor analysis and multiple regression analysis. RESULTS: Psychoneurological, respiratory, gastrointestinal and fatigue-related symptom clusters were identified, each of which was significantly negatively correlated with overall QoL, global health status/QoL and each functioning. The respiratory (ß = -0.60, P = 0.02) and fatigue-related symptom cluster (ß = -0.86, P = 0.02) were predictors of global health status/QoL; the fatigue-related symptom cluster predicted physical (ß = -1.68, P < 0.01), role (ß = -1.63, P < 0.01) and cognitive functioning (ß = -1.45, P < 0.01); the psychoneurological symptom cluster was a predictor of patients' emotional functioning (ß = -1.26, P < 0.01); and the psychoneurological (ß = -0.81, P < 0.01) and gastrointestinal symptom cluster (ß = -0.60, P = 0.05) predicted social functioning. CONCLUSIONS: Respiratory and fatigue-related symptom clusters were strong predictors of global health status/QoL; fatigue-related, psychoneurological and gastrointestinal symptom clusters had a negative impact on patients' functioning. Nurse practitioners should pay more attention to monitoring respiratory and fatigue-related symptom clusters to identify high-risk populations in time, and tailored interventions based on symptom clusters are needed to synergistically reduce the symptom burden, thereby improving patients' QoL.

RESUMO

Cell proliferation and function require nutrients, energy, and biosynthesis activity to duplicate repertoires for each daughter. It is therefore not surprising that tumor microenvironment (TME) metabolic reprogramming primarily orchestrates the interaction between tumor and immune cells. Tumor metabolic reprogramming affords bioenergetic, signaling intermediates, and biosynthesis requirements for both malignant and immune cells. Different immune cell subsets are recruited into the TME, and these manifestations have distinct effects on tumor progression and therapeutic outcomes, especially the mutual contribution of glycolysis and cholesterol metabolism. In particularly, glycolysis-cholesterol metabolic axis interconnection plays a critical role in the TME modulation, and their changes in tumor metabolism appear to be a double-edged sword in regulating various immune cell responses and immunotherapy efficacy. Hence, we discussed the signature manifestation of the glycolysis-cholesterol metabolic axis and its pivotal role in tumor immune regulation. We also highlight how hypothetical combinations of immunotherapy and glycolysis/cholesterol-related metabolic interventions unleash the potential of anti-tumor immunotherapies, as well as developing more effective personalized treatment strategies.

RESUMO

Background: The nuanced relationship between inflammatory bowel disease (IBD) and pancreatic cancer is noticed in recent years. However, the underlying causal effects of these two diseases are still unclear. Methods: The two-sample mendelian randomization (MR) was conducted to explore the causal effect of IBD condition on pancreatic cancer. Methods of Wald ratio, inverse variance weighted (IVW), MR-Egger, weighted median, and weighted mode were used to investigate the causal relationship between IBD and pancreatic cancer. Besides, Cochrane's Q test, MR-Egger, and leave-one-out method were further conducted to detect heterogeneity, stability, and pleiotropy of MR results. Results: In the MR analysis, we found Crohn's disease had a significant causal effect on pancreatic cancer. Specifically, Crohn's disease would increase 11.1% the risk of pancreatic cancer by the IVW method (p= 0.022), 33.8% by MR Egger (p= 0.015), by 35.3% by the Weighted model (p= 0.005). Regarding ulcerative colitis, there was no statistically significant causal effect observed on pancreatic cancer (p>0.05). Additionally, the pleiotropic test and Leave-one-out analysis both proved the validity and reliability of the present two-sample MR analyses. Conclusion: This study indicates that IBD, particularly Crohn's disease, is causality associated with increased risk of pancreatic cancer. Our results may help public health managers to make better follow-up surveillance of IBD patients.

RESUMO

BACKGROUND: Mucosal healing has become the primary treatment target for patients with Crohn's disease (CD). We aimed to develop a noninvasive and convenient tool to evaluate the endoscopic activity in patients with ileocolic CD. METHODS: A retrospective multicenter study including 300 CD patients (training, 210 patients; test, 90 patients) was conducted at two tertiary referral centers. Independent risk factors associated with endoscopic activity were explored, which were then combined into a comprehensive index. The predictive performance was evaluated with the area under receiver operating characteristic curve (ROC). Cohen's Kappa was adopted to examine the consistency between each indicator and endoscopic activity. RESULTS: A total of 210 CD patients were recruited in the training cohort. We found that Crohn's Disease Activity Index (CDAI), C-reactive protein (CRP) and platelet-to-lymphocyte percentage ratio (PLpR) were independently associated with endoscopic activity. Additionally, the comprehensive index generated from the above three indices achieved good discrimination and performed better than CDAI in AUC (0.849 vs. 0.769, P < 0.05). This was further well demonstrated by the external test cohort, which showed good discrimination (AUC: 0.84, 95% CI: 0.744-0.936). Intra-individual comparison revealed the comprehensive index to be superior in the prediction of endoscopic activity. In the subgroup analysis, the AUC of comprehensive index was significantly higher than CDAI especially in inflammatory phenotype (0.824 vs. 0.751, P < 0.05). CONCLUSION: Combining CDAI, CRP and PLpR significantly improved the accuracy for predicting endoscopic activity in ileocolic CD, which can help better monitor an endoscopic flare.

RESUMO

Liquid‒liquid phase separation (LLPS) is a phenomenon driven by weak interactions between biomolecules, such as proteins and nucleic acids, that leads to the formation of distinct liquid-like condensates. Through LLPS, membraneless condensates are formed, selectively concentrating specific proteins while excluding other molecules to maintain normal cellular functions. Emerging evidence shows that cancer-related mutations cause aberrant condensate assembly, resulting in disrupted signal transduction, impaired DNA repair, and abnormal chromatin organization and eventually contributing to tumorigenesis. The objective of this review is to summarize recent advancements in understanding the potential implications of LLPS in the contexts of cancer progression and therapeutic interventions. By interfering with LLPS, it may be possible to restore normal cellular processes and inhibit tumor progression. The underlying mechanisms and potential drug targets associated with LLPS in cancer are discussed, shedding light on promising opportunities for novel therapeutic interventions.

RESUMO

AIM: To examine the multidimensional properties of caregiver burden among family caregivers of patients with advanced cancer in a palliative context. DESIGN: A sequential, explanatory, mixed-method study was performed. METHODS: Family caregivers of patients diagnosed with advanced cancer were recruited from a palliative care department of a third-level hospital in Sichuan Province, China. The Caregiver Burden Inventory, Social Support Rating Scale and Connor-Davidson Resilience Scale were used to collect quantitative data, and a total of 150 caregivers were recruited from January 2022 to September 2022. Qualitative data were collected through semi-structured interviews, and a total of 22 caregivers were interviewed from October 2022 to November 2022. Survey data were analysed using descriptive statistics, and the factors of caregiver burden were identified using the Mann-Whitney U test, Kruskal-Wallis H test and Spearman correlations. Interpretative phenomenological analysis was performed to analyse the interview data to initially explore the multidimensions of caregiver burden. The following-a-thread method and convergence coding matrix were used for triangulation to examine the multidimensional properties of caregiver burden. RESULTS: The participants experienced a moderate level of caregiver burden (32.97 ± 13.09). Through triangulation, six meta-themes and nine meta-subthemes were identified as multidimensional properties of caregiver burden, including physical (too many caring tasks and poor health condition), emotional (strong negative emotions resulting from patients' suffering and insufficient and ineffective family communication), social (less social interaction and social role conflict) and economic burdens, factors that aggravate burden (prevention and control of COVID-19 and spousal relationship with patients) and factors that mitigate burden (social support). CONCLUSION: Multiple dimensions of caregiver burden were experienced by family caregivers of patients with advanced cancer in the palliative context. Family-centred palliative care must be further developed. IMPLICATIONS FOR THE PROFESSION: It is important to develop family-centred palliative care. Therefore, the focus must be on developing a rational understanding of palliative care in public and a culture-oriented death education in palliative units. IMPACT: This study adopted a mixed-method approach to comprehensively understand the phenomenon of and factors in caregiver burden in the Chinese palliative oncology context. Our findings suggest that family caregivers in palliative oncology experience a moderate level of caregiver burden, with dimensions including physical, emotional, social and economic burdens, among which emotional burden is the most prominent. The findings of this study provide policy makers and nurse practitioners with targets to be addressed in family-centred care in Chinese palliative units. REPORTING METHOD: The results of this study are reported based on the guidelines of the Mixed-Methods Article Reporting Standards. PATIENT OR PUBLIC CONTRIBUTION: Eligible caregivers were invited to participate in the study and semi-structured interviews. Nurse managers of the palliative unit helped us access the patient-management system.

RESUMO

OBJECTIVE: To explore the effectiveness of ePRO-based symptom management interventions on symptom burden, quality of life, and overall survival among patients with cancer for the first time and to explore the effects of different types of these interventions. BACKGROUND: Since advances in screening and treatment have transformed cancer into a chronic illness rather than a fatal disease, symptom management has become increasingly critical in oncology nursing. In recent decades, ePROs have been increasingly used in the symptom management of cancer patients to improve their symptom burden, quality of life and overall survival, but the existing findings are still inconsistent and equivocal. METHODS: A literature search was conducted in PubMed, Web-of-Science, CENTRAL, and CINAHL-Plus-with-Full-Text from inception to January 31, 2023. The quality of methodology and evidence were evaluated by the revised Cochrane risk-of-bias tool and the Grading of Recommendations, Assessment, Development, and Evaluation framework. All data were analyzed using R within the RStudio platform, and the effects of interventions were determined by calculating SMD, HR and 95 %CI. Subgroup analysis, sensitivity analysis and cumulative meta-analysis were performed, and statistical heterogeneity was examined by I2 statistic, P value, and Egger's or arcsine test. Statistical significance was defined as a two-tailed P value <0.05. RESULTS: A total of 23 randomized controlled trials with 7231 patients were included. The results indicated that ePRO-based symptom management interventions could improve the symptom burden (SMD = -0.19, 95 % CI [-0.33, -0.05], P < 0.01), quality of life (SMD = 0.16, 95 % CI [0.06, 0.25], P < 0.01) and overall survival (HR = 0.84, 95 % CI [0.73, 0.97], P = 0.02) of cancer patients. Subgroup analysis showed that targeted interventions for patients undergoing specific treatments were effective in relieving the symptom burden and enhancing quality of life. Short-term (≤3 months) interventions or reporting via telephone call contributed to alleviating the symptom burden, while quality of life improved when the intervention was more than three months in duration or not reported by telephone call. The pooled results of symptom burden and quality of life were stable, and the beneficial trends of all three outcomes were steady. The overall quality of methodology and evidence was moderate. CONCLUSIONS: We found that ePRO-based symptom management interventions are conducive to improving symptom burden, quality of life, and overall survival of cancer patients. In addition to encouraging the integration of ePRO-based interventions into routine oncology care, interventions with tailored plans, proper intensity and multidimensional supports need to be developed in the future to optimize the symptom management of cancer patients.

RESUMO

We report small molecular PROTAC compounds targeting the androgen receptor N-terminal domain (AR-NTD), which were obtained by tethering AR-NTD antagonists and different classes of E3 ligase ligands through chemical linkers. A representative compound, BWA-522, effectively induces degradation of both AR-FL and AR-V7 and is more potent than the corresponding antagonist against prostate cancer (PC) cells in vitro. We have shown that the degradation of AR-FL and AR-V7 proteins by BWA-522 can suppress the expression of AR downstream proteins and induce PC cell apoptosis. BWA-522 achieves 40.5% oral bioavailability in mice and 69.3% in beagle dogs. In a LNCaP xenograft model study, BWA-522 was also proved to be an efficacious PROTAC degrader, resulting in 76% tumor growth inhibition after oral administration of a dose of 60 mg/kg. This study indicates that BWA-522 is a promising AR-NTD PROTAC for the treatment of AR-FL- and AR-V7-dependent tumors.

RESUMO

PURPOSE: In this study, exercise interventions were evaluated for their effects on cancer-related fatigue (CRF) and quality of life (QoL) among cancer patients. DESIGN: A meta-analysis was performed. METHODS: We systematically searched the PubMed/Medline, Web of Science, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PsycINFO, and CINAHL databases, and gray literature sources including the Virginia Henderson International Nursing Library and Google Scholar. This study only included randomized controlled trials (RCTs) examining how exercise interventions affect CRF and QoL among cancer patients. Based on the Cochrane Risk-of-Bias Assessment Tool, version 2 (RoB 2) and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, the methodological quality of the included studies was evaluated. In addition, standardized mean differences (SMDs) and 95% confidence intervals (CIs) were applied to assess the intervention effect with respect to CRF and QoL. Data analysis was performed using Review Manager (version 5.4). RESULTS: There were a total of 1573 participants in the 28 included articles. According to the meta-analysis, CRF (SMD = -0.35, 95% CI: -0.63 to -0.07, p = 0.01) and QoL (SMD = 0.36, 95% CI: 0.20 to 0.53, p < 0.01) were positively affected by exercise interventions. Subgroup analyses revealed considerable improvements in CRF (SMD = -0.54, 95% CI: -1.00 to -0.09, p = 0.02) and QoL (SMD = 0.38, 95% CI: 0.16 to 0.59, p < 0.01) from aerobic exercise. An intervention duration less than 12 weeks had a better effect on CRF (SMD = -0.80, 95% CI: -1.43 to -0.17, p = 0.01) and QoL (SMD = 0.53, 95% CI: 0.21 to 0.85, p < 0.01), and three times per week was the most effective frequency in improving QoL (SMD = 0.69, 95% CI: 0.28 to 1.11, p < 0.01). Exercise intervention was more successful in improving CRF (SMD = -0.66, 95% CI: -1.10 to -0.21, p < 0.01) and QoL (SMD=-0.50, 95% CI: 0.23 to 0.78, p < 0.01) in female cancer patients. Sensitivity analyses showed that the pooled outcomes were reliable and stable. CONCLUSION: Exercise interventions are a workable approach to improve CRF and QoL among cancer patients. An aerobic exercise intervention of less than 12 weeks might be most effective in improving CRF and QoL, and three times per week might be the most appropriate frequency. Exercise might have a more positive effect on improving CRF and QoL in female cancer patients. Additionally, a larger number of high-quality RCTs should be conducted to further confirm the efficacy of exercise interventions on CRF and QoL among cancer patients.

RESUMO

Background: Statin use for cancer prevention has raised wide attention but the conclusions are still controversial. Whether statins use have exact causal effects on cancer prevention remains unclear. Methods: Based on the Genome-Wide Association Studies (GWAS) datasets from the large prospective UK Biobank and other consortium databases, two-sample mendelian randomization (MR) analysis was conducted to explore the causal effects of statins use on varied site-specific cancer risks. Five MR methods were applied to investigate the causality. The stability, heterogeneity, and pleiotropy of MR results were also evaluated. Results: The atorvastatin use could increase the risk of colorectal cancer (odd ratio (OR) = 1.041, p = 0.035 by fixed-effects inverse variance weighted (IVW) method (IVWFE), OR = 1.086, p = 0.005 by weighted median; OR = 1.101, p = 0.048 by weighted mode, respectively). According to the weighted median and weighted mode, atorvastatin could modestly decrease the risk of liver cell cancer (OR = 0.989, p = 0.049, and OR = 0.984, p = 0.004, respectively) and head and neck cancer (OR = 0.972, p = 0.020). Besides, rosuvastatin use could reduce the bile duct cancer risk by 5.2% via IVWEF method (OR = 0.948, p = 0.031). No significant causality was determined in simvastatin use and pan-cancers via the IVWFE or multiplicative random-effects IVW (IVWMRE) method if applicable (p > 0.05). There was no horizontal pleiotropy observed in the MR analysis and the leave-one-out analysis proved the stability of the results. Conclusion: The causalities between statin use and cancer risk were only observed in colorectal cancer and bile duct cancer in the European ancestry population. Future works are warranted to provide more robust evidence for supporting statin repurposing for cancer prevention.

RESUMO

BACKGROUND: Current studies have revealed that acceptance and commitment therapy (ACT) can alleviate the adverse effects of cancer; however, its effectiveness on the psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer remains unclear. AIMS: The aims of this study were to identify the effectiveness of ACT on psychological flexibility, fatigue, sleep disturbance, and quality of life of patients with cancer, and to explore moderators. METHODS: PubMed, Embase, Web of Science, CENTRAL, PsycINFO, CINAHL, CNKI, VIP, and Wanfang electronic databases were searched from inception to September 29, 2022. The Cochrane Collaboration's risk-of-bias assessment tool II and the Grading of Recommendations Assessment, Development, and Evaluation approach were used to evaluate evidence certainty. The data were analyzed using R Studio. The study protocol was registered with PROSPERO (CRD42022361185). RESULTS: The study included 19 relevant studies (1643 patients) published between 2012 and 2022. The pooled results showed that ACT significantly improved psychological flexibility (mean difference [MD] = -4.22, 95% CI [-7.86, -0.58], p = .02) and quality of life (Hedges' g = 0.94, 95% CI [0.59, 1.29], Z = 5.31, p < .01) but did not significantly improve fatigue (Hedges' g = -0.03, 95% CI [-0.24, 0.18], p = .75) or sleep disturbance (Hedges' g = -0.26, 95% CI [-0.82, 0.30], p = .37) in patients with cancer. Additional analyses revealed a 3-month sustainable effect on psychological flexibility (MD = -4.36, 95% CI [-8.67, -0.05], p < .05), and moderation analysis showed that intervention duration (ß = -1.39, p < .01) and age (ß = 0.15, p = .04) moderated the effects of ACT on psychological flexibility and sleep disturbance, respectively. LINKING EVIDENCE TO ACTION: Acceptance and commitment therapy demonstrates effectiveness for psychological flexibility and quality of life of patients with cancer, but there is a lack of evidence regarding its effects on fatigue and sleep disturbance. In clinical practice, ACT should be designed in more detail and rounded to achieve better results.

RESUMO

PURPOSE: To evaluate the incidence and identify the risk factors for radiotherapy-induced oral mucositis among patients with nasopharyngeal carcinoma. METHODS: A meta-analysis was conducted. Eight electronic databases (Medline, Embase, Cochrane Library, CINAHL Plus with Full Text, Web of Science, China National Knowledge Infrastructure, Wanfang Database, and Chinese Scientific Journals Database) were systematically searched from inception to 4 March 2023 for relevant studies. Study selection and data extraction were conducted by two independent authors. The Newcastle‒Ottawa scale was used for quality assessment among the included studies. Data synthesis and analyses were performed in R software package version 4.1.3 and Review Manager Software 5.4. The pooled incidence was calculated using proportions with 95% confidence intervals (CIs), and the risk factors were evaluated using the odds ratio (OR) with 95% CIs. Sensitivity analysis and predesigned subgroup analyses were also conducted. RESULTS: A total of 22 studies published from 2005 to 2023 were included. The results of the meta-analysis showed that the incidence of radiotherapy-induced oral mucositis was 99.0% among nasopharyngeal carcinoma patients, and the incidence of severe radiotherapy-induced oral mucositis was 52.0%. Poor oral hygiene, overweight before radiotherapy, oral pH < 7.0, the use of oral mucosal protective agents, smoking, drinking, combined chemotherapy, and the use of antibiotics at early treatment stage are risk factors for severe radiotherapy-induced oral mucositis. Sensitivity analysis and subgroup analyses also revealed that our results are stable and reliable. CONCLUSIONS: Almost all patients with nasopharyngeal carcinoma have suffered from radiotherapy-induced oral mucositis, and more than half of patients have experienced severe oral mucositis. Facilitating oral health might be the key focus of reducing the incidence and severity of radiotherapy-induced oral mucositis among nasopharyngeal carcinoma patients.

RESUMO

The evidence for chronic hepatitis B virus (HBV) infection and hepatocellular carcinoma (HCC) occurrence is well established. The hepatocyte epithelium carcinogenesis caused by HBV has been investigated and reviewed in depth. Nevertheless, recent findings from preclinical and observational studies suggested that chronic HBV infection is equally important in extrahepatic cancer occurrence and survival, specifically gastrointestinal system-derived cancers. Immune microenvironment changes (immune-suppressive cytokine infiltration), epigenetic modification (N6-methyladenosine), molecular signaling pathways (PI3K-Akt and Wnt), and serum biomarkers such as hepatitis B virus X (HBx) protein are potential underlying mechanisms in chronic HBV infection-induced extrahepatic cancers. This narrative review aimed to comprehensively summarize the most recent advances in evaluating the association between chronic HBV infection and extrahepatic cancer risk and explore the potential underlying molecular mechanisms in the carcinogenesis induction of extrahepatic cancers in chronic HBV conditions.

RESUMO

Androgen deprivation in cases of castration-resistant prostate cancer (CRPC) leads to adverse effects, including loss of muscle and bone mass and gain of subcutaneous fat. The tumor-specific suppression of androgen receptor (AR) signaling, while not global, may reduce side effects. We present a class of small-molecular conjugates consisting of an AR antagonist linked to a heat shock protein 90 (Hsp90) inhibitor. We demonstrate that the high accumulation of Hsp90 on the surface of CRPC cells allows uptake of conjugates and increases the enrichment of drugs in the tumor cells. After penetrating prostate cancer cells, the conjugates not only inhibit AR function by the antagonist component but also bind to Hsp90 and suppress the AR protein level. Compared to AR antagonists, these conjugates showed improved tumor-targeting ability and enhanced potency against Enzalutamide-resistant 22Rv1 cells.

RESUMO

OBJECTIVES: To identify the factors associated with caregiver burden in Chinese lung cancer families and to detect whether family resilience mediates the effect of perceived social support on caregiver burden. DATA SOURCES: From October 2021 to March 2022, a total of 213 family caregivers of patients with lung cancer from a public hospital in Sichuan Province, China, completed the Zarit Burden Interview (ZBI), the Perceived Social Support Scale (PSSS), and the Family Resilience Assessment Scale (FRAS). The Mann-Whitney U test and the Kruskal-Wallis H test were used to identify the influencing factors of family caregiver burden, and the bootstrapping method was conducted to detect the mediating role of family resilience. CONCLUSION: In this study, family caregiver burden could be influenced by caregiver age, caregivers' relationships with patients, and patients' self-care degree; family resilience was found to mediate the relationship between caregivers' perceived social support and caregiver burden. IMPLICATION FOR NURSING PRACTICE: Our study manifested that factor from both the patients' and caregivers' sides could influence caregiver burden of lung cancer family caregivers. The results provide further evidence that lung cancer care should be family-centered, and relevant family-supportive systems should be further developed in this field.
