ABSTRACT

The autonomic nervous system (ANS) regulates involuntary bodily functions such as blood pressure, heart rate, breathing, and digestion, in addition to controlling motivation and behavior. In older adults, the ANS is dysregulated, which changes the ability of the ANS to respond to physiological signals, regulate cardiovascular autonomic functionality, diminish gastric motility, and exacerbate sleep problems. For example, a decrease in heart rate variability, or the variation in the interval between heartbeats, is one of the most well-known alterations in the ANS associated with health issues, including cardiovascular diseases and cognitive decline. The inability to perform fundamental activities of daily living and compromising the physiological reactivity or motivational responses of older adults to moving toward or away from specific environmental stimuli are significant negative consequences of chronic and geriatric conditions that pose grave threats to autonomy, health, and well-being. The most updated research has investigated the associations between the action responsiveness of older adults and the maintenance of their physiological and physical health or the development of mental and physical health problems. Once autonomic dysfunction may significantly influence the development of different age-related diseases, including ischemic stroke, cardiovascular disease, and autoimmune diseases, this review aimed to assess the relationship between aging and autonomic functions. The review explored how motivational responses, physiological reactivity, cognitive processes, and lifelong developmental changes associated with aging impact the ANS and contribute to the emergence of health problems.

ABSTRACT

The term 'cancer' refers to >100 disorders that progressively manifest over time and are characterized by uncontrolled cell division. Although malignant growth can occur in virtually any human tissue, the underlying mechanisms underlying all forms of cancer are consistent. The International Agency for Research on Cancer's annual GLOBOCAN 2020 report provided an update on the global cancer incidence and mortality. Excluding non-melanoma skin cancer, the report predicts that there will be 19.3 million new cancer cases and >10 million cancer-related fatalities in 2023. Lung, prostate, and colon cancers are the most prevalent and lethal cancers in males. It was recognized that post-translational modifications (PTMs) of proteins are necessary for almost all cellular biological processes, as well as in cancer development and metastasis to other bodily organs. Thus, PTMs have a considerable impact on how proteins behave. Various PTMs may have harmful roles by affecting the hallmarks of cancer, metabolism and the regulation of the tumor microenvironment. PTMs and genetic changes/mutations are essential in carcinogenesis and cancer development. A pivotal PTM mechanism is protein ubiquitination. Of note, the rate-limiting stage of the protein ubiquitination cascade is hypothesized to be E3-ligase-mediated ubiquitination. Numerous studies revealed that the neural precursor cell expressed developmentally downregulated protein 4 (NEDD4) E3 ligase is among the E3 ubiquitin ligases that have essential roles in cellular processes. It regulates protein degradation and substrate ubiquitination. In addition, it has been shown that NEDD4 primarily functions as an oncogene in various malignancies but can also act as a tumor suppressor in certain types of tumor. In the present review, the roles of NEDD4 as an anticancer protein in various high-incidence male malignancies and the significance of NEDD4 as a potential cancer therapeutic target are discussed. In addition, the targeting of NEDD4 as a therapeutic strategy for the treatment of human malignancies is explored.

ABSTRACT

Brain tumors account for less than 2% of all malignancies. However, they are associated with the highest morbidity and mortality rates among all solid tumors. The most common malignant primary brain tumors are glioma or glioblastoma (GBM), which have a median survival time of about 14 months, often suffer from recurrence after a few months following treatment, and pose a therapeutic challenge. Despite recent therapeutic advances, the prognosis for glioma patients is poor when treated with modern therapies, including chemotherapy, surgery, radiation, or a combination of these. Therefore, discovering a new target to treat brain tumors, particularly glioma, might be advantageous in raising progression-free survival and overall survival (OS) rates. Statins, also known as competitive HMG-CoA reductase inhibitors, are effective medications for reducing cholesterol and cardiovascular risk. The use of statins prior to and during other cancer treatments appears to enhance patient outcomes according to preclinical studies. After surgical resection followed by concurrent radiation and treatment, OS for patients with GBM is only about a year. Statins have recently emerged as potential adjuvant medications for treating GBM due to their ability to inhibit cell growth, survival, migration, metastasis, inflammation, angiogenesis, and increase apoptosis in-vitro and in-vivo studies. Whether statins enhance clinical outcomes, such as patient survival in GBM, is still debatable. This study aimed to explore the effects of statin therapy in the context of cancer treatment, with a particular focus on GBM.

ABSTRACT

BACKGROUND: Australia has a large population of immigrant women from Arabic-speaking countries. The aim of this study was to examine breast cancer tumour and surgical treatment features for women born in Arabic-speaking countries and compare them to women born in Australia and other countries. Another aim was to consider how this information can inform clinical care for this multicultural population. METHODS: This is a retrospective audit of an institutional breast cancer database. Demographic, tumour and surgical treatment data were extracted for the Arab women and compared to Australian-born women (comparison 1) and to women born in all other countries (comparison 2); chi-squared analysis was performed to test for differences between groups. RESULTS: A total of 2086 cases with country of birth information were identified, of whom 139 women (6.7%) were born in Arabic-speaking countries, 894 (42.8%) were born in Australia and 1053 (50.4%) were born in other countries (71 nations). Arab women tended to be younger (P = 0.013), more disadvantaged (P < 0.001), were more likely to have symptomatic rather than screen-detected breast cancer (P < 0.001), had a higher rate of high grade (P = 0.021), HER2-positive (P = 0.025) breast cancer compared to Australian-born women or others. There was no difference in tumour (pT) stage, rate of breast conservation versus mastectomy, re-excision and contralateral prophylactic mastectomy between groups. Australian-born women were more likely to undergo breast reconstruction after mastectomy (P < 0.001); reconstruction rate was >29% in all groups. CONCLUSION: Women born in Arabic-speaking countries were younger, more disadvantaged and showed more aggressive tumour features. This has implications for supportive care during treatment and survivorship.
