Abstract
Objectives This research aims to provide concrete insight into cancer incidence, mortality, and survivorship dynamics among African women between 2016 and 2020. Methods The study computes the Mortality-to-Incidence Ratio (MIR) for 53 countries in Africa with available mortality and incidence data. It uses relevant Life Tables to obtain the 5-year Relative Survival rate for women in different age cohorts based on General Survival Rate and 5-year Cancer Prevalence data from the World Health Organization (WHO). The study performs an analysis of variance tests. Results The results of the initial data analysis show that women in the top economies in Africa have the highest cancer incidence and mortality. The study also finds that women in Northern and Southern African countries have higher relative survival rates and lower MIR than other African regions. ANOVA results confirm statistically significant differences in 5-year relative survival across the African regions. The relative survival at 5 years was an average of 45% across all age groups within the continent although relative survival is highest among females aged 5-19 and 80-84. The lowest relative survival rates are seen for infants (0-4), adolescents and young adults (25-29), and the very elderly (85+). Conclusion The study concludes that while cancer incidence in Africa is linked to affluence, survival is very challenging, especially for the least developed economies in Western, Eastern, and Central Africa. The results indicate the need for crucial intervention in the continent concerning awareness, research, and data collection methodology.

Abstract
Gastrointestinal malignancies, including colon adenocarcinoma (COAD) and liver hepatocellular carcinoma (LIHC), remain leading causes of cancer-related deaths worldwide. To better understand the underlying mechanisms of these cancers and identify potential therapeutic targets, we analyzed publicly accessible Cancer Genome Atlas datasets of COAD and LIHC. Our analysis revealed that differentially expressed genes (DEGs) during early tumorigenesis were associated with cell cycle regulation. Additionally, genes related to lipid metabolism were significantly enriched in both COAD and LIHC, suggesting a crucial role for dysregulated lipid metabolism in their development and progression. We also identified a subset of DEGs associated with mitochondrial function and structure, including upregulated genes involved in mitochondrial protein import and respiratory complex assembly. Further, we identified mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase (HMGCS2) as a crucial regulator of cancer cell metabolism. Using a genome-scale metabolic model, we demonstrated that HMGCS2 suppression increased glycolysis, lipid biosynthesis, and elongation while decreasing fatty acid oxidation in colon cancer cells. Our study highlights the potential contribution of dysregulated lipid metabolism, including ketogenesis, to COAD and LIHC development and progression and identifies potential therapeutic targets for these malignancies.

Salami AA, Kanmodi KK, Amzat J. The roles of chaplains in dispelling cancer myths in Nigeria: A narrative review. Health Sci Rep 2023; 6:e1502. [PMID: 37614282 PMCID: PMC10442495 DOI: 10.1002/hsr2.1502] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 08/25/2023] Open
Abstract
Background and Aims The epidemiological burden of cancer in Africa, and Nigeria in particular, has been increasing significantly over the past few decades due to exposure to numerous risk factors as well as belief in various myths and misconceptions. Chaplains can play crucial roles in dispelling these myths and misconceptions about cancer among people. Therefore, this study seeks to review the epidemiological burden, risk factors, and myths relating to cancer and the roles of chaplains in dispelling cancer myths in Nigeria. Methods This paper is a narrative review that relied on secondary sources obtained through a thorough literature search of relevant articles on multiple electronic databases including PubMed, Google Scholar, and Web of Science. Published books, journal articles, and other published materials that were written in English were consulted in line with the objectives of this study. Both theoretical and empirical papers were used for this review. Results Cancers are associated with risk factors including exposure to chemicals, ultraviolet radiation, harmful tobacco and alcohol use, exposure to human papillomavirus (HPV), and these factors may vary with age, cultural beliefs (myths and misconceptions), and socioeconomic factors among others. Chaplains, however, have crucial roles to play in dispelling cancer myths in Nigeria. These roles include counseling, advocacy, education, and psycho-social support which may be limited by challenges such as spiritual ambiguity, inadequate training of healthcare providers and limited time/resources. These challenges can be addressed by training healthcare providers and incorporating chaplain practice in Nigerian healthcare. Conclusion The role of chaplains in dispelling cancer myths in Nigeria is crucial despite the numerous challenges. Hence, an urgent address of these challenges will be instrumental in ensuring effective chaplain practice in Nigeria.

Abstract
Immune checkpoint inhibitors, including anti-PD-1 and anti-CTLA-4 therapies, are used to (re)activate the immune system to treat cancer. Despite promising results, a large group of patients does not respond to checkpoint inhibition. In the vulnerability-stress model of behavioral medicine, behavioral factors, such as stress, exercise and classical pharmacological conditioning, predict cancer incidence, recurrence and the efficacy of conventional cancer treatments. Given the important role of the immune system in these processes, certain behavior may be promising to complement immune checkpoint inhibition therapy. Here, we discuss the preliminary evidence and suitability of three behavioral mechanisms, i.e. stress modulation, exercise and classical pharmacological conditioning for the benefit of immunotherapy. It is crucial to study the potential beneficial effects of behavioral strategies that support immunotherapeutic anti-tumor effects with rigorous experimental evidence, to exploit behavioral mechanisms in improving checkpoint inhibition efficacy.

Abstract
PURPOSE Chronic diseases and cardiovascular diseases (CVD) have been independently linked to poorer cancer outcomes. This study investigated whether gastric cancer patients with hypertension, diabetes, or dyslipidemia have higher mortality if diagnosed with CVD in the past year before cancer diagnosis. MATERIALS AND METHODS Data were obtained from the National Health Insurance database for 2002 to 2019. The study population consisted of gastric cancer patients with hypertension, diabetes, or dyslipidemia. The outcome measure was 5-year mortality in relation to incident status of CVD within 1 year before cancer diagnosis. A survival analysis was conducted using the Cox proportional hazards model. Subgroup analysis was conducted according to age, economic status, and type of hospital first visited for cancer treatment. RESULTS Of a total of 6458 individuals, 2123 (32.7%) were diagnosed with CVDs in the past year before cancer diagnosis. Compared to participants without a history of CVD, those who were diagnosed with CVD showed a higher risk of 5-year mortality (hazard ratio 1.259, 95% confidence interval 1.138-1.394). The extent to which the mortality risk differed between those with and without CVD was greater for individuals of low economic status and in those receiving their initial cancer treatment in a general hospital. CONCLUSION Patients with gastric cancer and hypertension, diabetes, or dyslipidemia diagnosed with CVD within 1 year before their cancer diagnosis had a higher mortality risk, emphasizing the importance of managing cancer patients with chronic disease and subsequent incidence of CVDs.

Abstract
Although Japan has a well-established cancer screening program and has implemented several initiatives to increase screening rates, levels of cancer screening can be further improved. Based on a rational decision-making framework, this study examines the role of financial literacy and financial education, which measure peoples' knowledge about investment and savings, respectively, in improving cancer screening rates in Japan. The main data were extracted from Osaka University's Preference Parameters Study for 2011. The dependent variable was the number of cancer screenings while the two main independent variables were financial literacy and financial education. Ordered probit regression models were run to test the association between financial literacy, financial education, and the number of cancer screenings. The results showed a positive relationship between financial education and cancer screening behavior in Japan, while no significant association was observed between financial literacy and screening behavior. Furthermore, according to findings stratified by three age groups, the positive association between financial education and cancer screening behavior was particularly evident in 50- to 59-year-olds, while the effects of other demographic, socioeconomic, and risky health behavior variables were not consistent. It is imperative that implementation of more financial education programs is an effective intervention to encourage cancer screening behavior in Japanese populations.

Abstract
BACKGROUND There is limited research suggesting that women with Benign Breast Disease (BBD) experience psychological distress similar to breast cancer (BC) women. We aimed to examine hopelessness and its related factors in BC and BBD women. METHOD This was a cross-sectional study. The Beck Hopelessness Scale and the Beck Depression Inventory were administered to 51 BBD and 52 BC women. RESULTS BC women had higher hopelessness scores as compared to those with BBD (6.9 ± 4.8 vs. 4.9 ± 3.6; p = .018). After controlling for confounding variables, depression and suicidal ideation/behavior were significantly associated with hopelessness in the BBD group, while only a lower socioeconomic status was associated with higher hopelessness scores in the BC group. CONCLUSION We found that not only BC but also BBD lead to a psychological burden. Early detection and handling of hopeless feelings and thoughts that may arise in this population are recommended.

Abstract
This review article contains a concise consideration of genetic and environmental risk factors for colorectal cancer. Known risk factors associated with colorectal cancer include familial and hereditary factors and lifestyle-related and ecological factors. Lifestyle factors are significant because of the potential for improving our understanding of the disease. Physical inactivity, obesity, smoking and alcohol consumption can also be addressed through therapeutic interventions. We also made efforts to systematize available literature and data on epidemiology, diagnosis, type and nature of symptoms and disease stages. Further study of colorectal cancer and progress made globally is crucial to inform future strategies in controlling the disease's burden through population-based preventative initiatives.
