Germline testing for prostate cancer is on the increase, with clinical implications risk assessment, treatment, and management. Regardless of family history, NCCN recommends germline patients metastatic, regional, very-high-risk localized, high-risk localized cancer. Although African ancestry a significant factor aggressive cancer, due to lack available data no criteria have been established ethnic minorities.Through deep sequencing, we interrogated 20 most common panel genes in 113 Black...

African ancestry is a significant risk factor for prostate cancer and advanced disease. Yet, genetic studies have largely been conducted outside the context of Sub-Saharan Africa, identifying 278 common variants contributing to multiethnic polygenic score, with rare focused on panel roughly 20 pathogenic genes. Based this knowledge, we are unable determine or differentiate status interrogating whole genome data 113 Black South men. To further assess potentially functional variant...

Abstract Prostate cancer (PCa) is highly heritable, with men of African ancestry at greatest risk and associated lethality. Lack representation in genomic data means germline testing guidelines exclude for Africans. Established that structural variations (SVs) are major contributors to human disease prostate tumourigenesis, their role under-appreciated familial therapeutic testing. Utilising clinico-methodologically matched deep-sequenced whole-genome 113 versus 57 European PCa patients, we...

Discrimination in education is commonly associated with face-to-face interactions between teachers and students. However, e-learning environments can also foster discrimination. Despite existing research on discrimination traditional education, limited studies address this issue virtual particularly nursing education. This study aimed to explore the factors contributing perceived among midwifery students, focusing underlying causes conditions that shape these experiences. A qualitative...

Prostate cancer shows significant racial disparity, with men of African ancestry disproportionately impacted. While prostate health disparity studies focus on elucidating the contributing socioeconomic, lifestyle, environmental, biological and underlying genetic factors, genome sequencing is helping to reduce burden through disease stratification treatment. Sub-Saharan Africa has, till now, been excluded from these benefits. The new Cancer Precision Health Africa1K Equity Research Outcomes...

Prostate cancer (PCa) is a significant health burden in Sub-Saharan Africa, with mortality rates loosely linked to African ancestry. Yet studies aimed at identifying contributing risk factors are lacking within the continent and as such exclude for ancestral diversity.

Background Although survival from colorectal cancer (CRC) has improved substantially in recent decades, people with advanced age still have a high likelihood of mortality this disease. Nonetheless, few studies investigated how stage, subsite and comorbidities contribute collectively to poor prognosis older CRC. Here, we decided explore the association measures other variables influenced association. Methods Using linkage several administrative datasets, risk death among CRC cases during...

Abstract Background Advanced age is associated with decreased likelihood of colorectal cancer treatment. Here, we investigated the extent to which comorbidities are accountable for this lesser Methods Using population‐based datasets, pattern care among CRC cases in South Australia during 2004–2013 was investigated.
