Tumour Virus Res 2024; 18:200289. [PMID: 38977263 DOI: 10.1016/j.tvr.2024.200289] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 07/02/2024] [Accepted: 07/03/2024] [Indexed: 07/10/2024] Open
Abstract
DNA viruses are common in the human population and act as aetiological agents of cancer on a large scale globally. They include the human papillomaviruses (HPV), Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpesvirus (KSHV), hepatitis viruses, and human polyomaviruses. Oncogenic viruses employ different mechanisms to induce cancer. Notably, cancer only develops in a minority of individuals who are infected, usually following protracted years of chronic infection. The human papillomaviruses (HPVs) are associated with the highest number of cancer cases, including cervical cancer and other epithelial malignancies. Hepatitis B virus (HBV) and the RNA virus hepatitis C (HCV) are significant contributors to hepatocellular cancer (HCC). Other oncoviruses include Epstein-Barr virus (EBV), Kaposi sarcoma-associated herpes virus (KSHV), human T-cell leukemia virus (HTLV-I), and Merkel cell polyomavirus (MCPyV). The identification of these infectious agents as aetiological agents for cancer has led to reductions in cancer incidence through preventive interventions such as HBV and HPV vaccination, HPV-DNA based cervical cancer screening, antiviral treatments for chronic HBV and HCV infections, and screening of blood for transfusion for HBV and HCV. Successful efforts to identify additional oncogenic viruses in human cancer may provide further understanding of the aetiology and development of cancer, and novel approaches for prevention and treatment. Cervical cancer, caused by HPV, is the leading gynaecological malignancy in LMICs, with high age-standardised incidence and mortality rates, HCC due to HBV is an important cause of cancer deaths, and the burden of other cancer attributable to infections continues to rise globally. Hence, cancers attributable to DNA viruses have become a significant global health challenge. These viruses hence warrant continued attention and interrogation as efforts to understand them further and device further preventive interventions are critical.

Abstract
The COVID-19 pandemic has highlighted how infodemics (defined as an overabundance of information, including misinformation and disinformation) pose a threat to public health and could hinder individuals from making informed health decisions. Although public health authorities and other stakeholders have implemented measures for managing infodemics, existing frameworks for infodemic management have been primarily focused on responding to acute health emergencies rather than integrated in routine service delivery. We review the evidence and propose a framework for infodemic management that encompasses upstream strategies and provides guidance on identifying different interventions, informed by the four levels of prevention in public health: primary, secondary, tertiary, and primordial prevention. On the basis of a narrative review of 54 documents (peer-reviewed and grey literature published from 1961 to 2023), we present examples of interventions that belong to each level of prevention. Adopting this framework requires proactive prevention and response through managing information ecosystems, beyond reacting to misinformation or disinformation.

Abstract
Cancer diagnosis and treatment can be physically arduous, disrupting patients' social and work lives. Understanding the extent of these problems is key to addressing patients' needs, but specific psychosocial challenges have not yet been well studied in resource-limited settings. A qualitative study was conducted in the capital and two regions of Ethiopia with the aim of exploring psychosocial challenges among cancer patients. A total of 14 in-depth interviews (IDIs) and 16 focus group discussions (FGDs) were done with cancer patients, health professionals, community representatives, and religious leaders. Four separate interview guides were used to facilitate the interviews and discussions. All transcribed documents, field notes, and reflexive memos were entered into NVivo 12 software, and deductive thematic analysis using the social-ecological model was applied to summarize the main findings. At an individual level, emotional distress, suicidal risk, denial, and refusal of treatment were identified immediately after diagnosis while hopelessness, feeling depressed, and fear of death were commonly reported psychosocial challenges during the course of treatment. Involvement of family members in major treatment decisions was recognized at an interpersonal level. Our result also revealed that cancer patients had strong social support from family members and close friends. In the community, traditional medicine and religious rituals were considered an alternative treatment for cancer. The findings indicate that counselling and psychoeducation are crucial for cancer patients, family members, and close friends. Awareness creation programmes should be delivered through collaboration with religious leaders and traditional healers.

Abstract
INTRODUCTION In an ageing society, older adults are the main users of healthcare services, and Chinese healthcare systems have been struggling to meet the care demand of older adults. Due to the illness, many older inpatients cannot finish daily activities independently and require healthcare from caregivers. Evaluating the care needs of older adults and exploring the factors affecting safe care at multiple levels are conducive to providing systematic care services for older inpatients. This study aims to examine which and how factors impact safe care for older inpatients and propose a safe care theory to provide directions on improving the safe care system in the hospital. METHODS AND ANALYSIS A mixed-methods study with three interrelated research streams will be designed. (1) A safe care concept model: we will conduct a scoping review to extract the facilitators and barriers influencing the safe care of older inpatients and construct a concept model based on the socio-ecological model and the Yorkshire Contributory Factors Framework. (2) A safe care theory model: we will conduct a qualitative study with thematic analysis (aimed at older inpatients, caregivers and nurses) to define the concept connotations and propose a theory model. (3) A safe care theory: we will use the scales related to the theory model to test the concepts and statements. We will revise the theory model and derive a safe care theory based on the mixed-methods study results. This study will start in October 2023 and end in October 2025. ETHICS AND DISSEMINATION This study was approved by the ethics committee (No. 20221598). All participants will be provided with consent forms prior to data collection. The study will be disseminated via peer-reviewed manuscripts and conferences. TRIAL REGISTRATION NUMBER ChiCTR2300067421.

Abstract
BACKGROUND Advocacy is an expectation of the nursing profession. Nursing curricula should include opportunities for advocacy skills building at multiple levels of potential effect. Analyses of student performances during these advocacy exercises provide insight into how well students understand the multifactorial nature of most public health issues. METHOD A socioecological model was used to evaluate nursing students' advocacy responses to food-insecurity scenarios during a guided online discussion activity aimed at advocacy skills building. RESULTS Student recommendations were categorized as individual, interpersonal, organizational, community, and policy interventions, with subcategories at each socioecological level. CONCLUSION Recommendations are given for future educational research specific to advocacy skills building. Implications for nursing education at each socioecological level also are discussed.

Abstract
Considerable progress has been made in cancer drug development in recent decades. However, for people in low- and middle-income countries, including Malaysia, many of these drugs are not readily available. During the 2nd Malaysian Association for Cancer Research (MACR) International Scientific Conference, a forum discussion was held to address these challenges and explore strategies to improve access to cancer medicines in the country. This paper presents the results of the said forum discussion. A few challenges to cancer drug access were highlighted, including lengthy approval and regulatory practices, cost of medicines, and manufacturing barriers. Besides, a few strategies for mitigating some of these challenges were proposed, such as mechanisms for cost reduction, uptake of biosimilars and generics, local manufacturing, public-private partnerships, strengthening the role of insurance companies, funding and regulation, and advocacy for fair pricing, by drawing examples from cancer medicines access initiatives in Malaysia and initiatives for different disease groups. Overall, this paper provides a comprehensive overview of the challenges and strategies for improving access to cancer medicines in Malaysia and provides valuable insights for policymakers, healthcare providers, the pharmaceutical industry, cancer patients, cancer support groups, and other stakeholders working on this important issue.

Abstract
Introduction At present, cancer remains a persistent public health challenge facing the whole world. Studies have found that PTPN21 is associated with the development of cancer. However, the prognostic potential of PTPN21 in pan-cancer remains unclear. In this work, we aimed to analyze the expression and prognostic value of PTPN21 in pan-cancer and to further study the relationship between PTPN21 and immune infiltration. Material and methods TCGA and GEO data were used for expression and survival analysis. Genetic alterations in PTPN21 from TCGA cancer were studied in cBioPortal. TIMER2 was used to evaluate the correlation between PTPN21 expression and immune infiltration. The R packages "ggplot2" and "clusterProfiler" were used for GO and KEGG analysis. Results PTPN21 was found to be a valuable diagnostic biomarker in multiple cancers, including bladder urothelial carcinoma (BLCA), kidney renal clear cell carcinoma (KIRC), kidney renal papillary cell carcinoma (KIRP), and lung squamous cell carcinoma (LUSC). In addition, we observed that PTPN21 expression was associated with a variety of tumor mutations. Our results indicated a correlation between PTPN21 expression and immune infiltration. Enrichment analysis showed that PTPN21 was mainly involved in the regulation of neuroactive ligand-receptor interaction. Conclusions Our study showed that PTPN21 expression is associated with clinical prognosis, mutation, and immune infiltration of tumors. PTPN21 may be a potential biomarker for many cancers, especially in KIRC.
