    Background: Several biological factors such as bacterial infections and immunological status are implicated in predisposing individuals to bladder cancer. Bacterial infection of urinary tract has been related to increase the risk of bladder cancer. Patients and Methods: Resected tumors of a total of 73 patients were obtained under sterile surgical conditions. Biopsy processing samples and culture procedures of biopsy samples were mentioned in the text. Results: Bacterial growth was observed in 48 biopsy tissues of those patients represent (65.8%) while, 25(34.2%) yielded no growth (negative results). It is obvious that E. coli is the most predominant organisms followed by K. pneumoniae and Ps. Aeruginosa. The other uropathogens isolated more or less of equal distribution. Conclusion: High frequency and great variety of bacteria in cystectomy specimens removed from cancer of urinary bladder. They were often Gram-negative pathogens (primarily Enterobacteriaceae)

    BACKGROUND: A growing Muslim population in the UK suggests the need for healthcare professionals (HCPs) to gain a better understanding of how the Islamic faith influences health related perceptions and healthcare seeking behaviour. Although some researchers have explored the experiences of Muslim women as recipients of healthcare, little attention has been paid to the challenges HCPs face as service providers on a day-to-day basis whilst caring for Muslim women. The aim of this study was to investigate HPCs lived experiences of providing maternity care for Muslim women. METHOD: Data was collected through twelve semi-structured one-to-one qualitative interviews with HCPs in a large National Health Service (NHS) maternity unit located in the North West of England. Interview participants included Community and specialist clinic (e.g. clinic for non-English speakers), Midwives in a variety of specialist roles (7), Gynaecology Nurses (2), Breastfeeding Support Workers (2) and a Sonographer (1). The audio-recorded interviews were transcribed and analysed thematically. RESULTS: The majority of participants expressed an understanding of some religious values and practices related to Muslim women, such as fasting the month of Ramadhan and that pregnant and breastfeeding women are exempt from this. However, HCPs articulated the challenges they faced when dealing with certain religious values and practices, and how they tried to respond to Muslim women's specific needs. Emerging themes included: 1) HCPs perceptions about Muslim women; 2) HCPs understanding and awareness of religious practices; 3) HCPs approaches in addressing and supporting Muslim women's religious needs; 4) Importance of training in providing culturally and religiously appropriate woman-centred care. CONCLUSION: Through this study we gained insight into the day-to-day experiences of HCPs providing care provision for Muslim women. HCPs showed an understanding of the importance of religious and cultural practices in addressing the needs of Muslim women as part of their role as maternity care providers. However, they also identified a need to develop training programmes that focus on cultural and religious practices and their impact on women's health care needs. This will help support HCPs in overcoming the challenges faced when dealing with needs of women from different backgrounds

    Background Palestine is a low income country with scarce resources, which is seeking independence. This paper discusses the high levels of mental health need found amongst Palestinian people, and examines services, education and research in this area with particular attention paid to the West Bank. Methods CINAHL, PubMed, and Science Direct were used to search for materials. Results and conclusion Evidence from this review is that there is a necessity to increase the availability and quality of mental health care. Mental health policy and services in Palestine need development in order to better meet the needs of service users and professionals. It is essential to raise awareness of mental health and increase the integration of mental health services with other areas of health care. Civilians need their basic human needs met, including having freedom of movement and seeing an end to the occupation. There is a need to enhance the resilience and capacity of community mental health teams. There is a need to increase resources and offer more support, up-to-date training and supervision to mental health teams

    The politics and aesthetics of commemoration: national days in southern Africa

    Get PDF
    The contributions to the special section in this issue study recent independence celebrations and other national days in South Africa, Namibia, Zimbabwe, Madagascar and the Democratic Republic of Congo. They explore the role of national days in state-making and nation-building, and examine the performativity of nationalism and the role of performances in national festivities. Placing the case studies in a broader, comparative perspective, the introduction first discusses the role of the state in national celebrations, highlighting three themes: firstly, the political power-play and contested politics of memory involved in the creation of a country’s festive calendar; secondly, the relationship between state control of national days and civic or popular participation or contestation; and thirdly, the complex relationship between regional and ethnic loyalties and national identifications. It then turns to the role of performance and aesthetics in the making of nations in general, and in national celebrations in particular. Finally, we look at the different formats and meanings of national days in the region and address the question whether there is anything specific about national days in southern Africa as compared to other parts of the continent or national celebrations world-wide.Web of Scienc

    Human resources requirements for highly active antiretroviral therapy scale-up in Malawi

    <p>Abstract</p> <p>Background</p> <p>Twelve percent of the adult population in Malawi is estimated to be HIV infected. About 15% to 20% of these are in need of life saving antiretroviral therapy. The country has a public sector-led antiretroviral treatment program both in the private and public health sectors. Estimation of the clinical human resources needs is required to inform the planning and distribution of health professionals.</p> <p>Methods</p> <p>We obtained data on the total number of patients on highly active antiretroviral treatment program from the Malawi National AIDS Commission and Ministry of Health, HIV Unit, and the number of registered health professionals from the relevant regulatory bodies. We also estimated number of health professionals required to deliver highly active antiretroviral therapy (HAART) using estimates of human resources from the literature. We also obtained data from the Ministry of Health on the actual number of nurses, clinical officers and medical doctors providing services in HAART clinics. We then made comparisons between the human resources situation on the ground and the theoretical estimates based on explicit assumptions.</p> <p>Results</p> <p>There were 610 clinicians (396 clinical officers and 214 physicians), 44 pharmacists and 98 pharmacy technicians and 7264 nurses registered in Malawi. At the end of March 2007 there were 85 clinical officer and physician full-time equivalents (FTEs) and 91 nurse FTEs providing HAART to 95,674 patients. The human resources used for the delivery of HAART comprised 13.9% of all clinical officers and physicians and 1.1% of all nurses. Using the estimated numbers of health professionals from the literature required 15.7–31.4% of all physicians and clinical officers, 66.5–199.3% of all pharmacists and pharmacy technicians and 2.6 to 9.2% of all the available nurses. To provide HAART to all the 170,000 HIV infected persons estimated as clinically eligible would require 4.7% to 16.4% of the total number of nurses, 118.1% to 354.2% of all the available pharmacists and pharmacy technicians and 27.9% to 55.7% of all clinical officers and physicians. The actual number of health professionals working in the delivery of HAART in the clinics represented 44% to 88.8% (for clinical officers and medical doctors) and 13.6% and 47.6% (for nurses), of what would have been needed based on the literature estimation.</p> <p>Conclusion</p> <p>HAART provision is a labour intensive exercise. Although these data are insufficient to determine whether HAART scale-up has resulted in the weakening or strengthening of the health systems in Malawi, the human resources requirements for HAART scale-up are significant. Malawi is using far less human resources than would be estimated based on the literature from other settings. The impact of HAART scale-up on the overall delivery of health services should be assessed.</p

    Topoisomerase II-Mediated DNA Damage Is Differently Repaired during the Cell Cycle by Non-Homologous End Joining and Homologous Recombination

    Topoisomerase II (Top2) is a nuclear enzyme involved in several metabolic processes of DNA. Chemotherapy agents that poison Top2 are known to induce persistent protein-mediated DNA double strand breaks (DSB). In this report, by using knock down experiments, we demonstrated that Top2α was largely responsible for the induction of γH2AX and cytotoxicity by the Top2 poisons idarubicin and etoposide in normal human cells. As DSB resulting from Top2 poisons-mediated damage may be repaired by non-homologous end joining (NHEJ) or homologous recombination (HR), we aimed to analyze both DNA repair pathways. We found that DNA-PKcs was rapidly activated in human cells, as evidenced by autophosphorylation at serine 2056, following Top2-mediated DNA damage. The chemical inhibition of DNA-PKcs by wortmannin and vanillin resulted in an increased accumulation of DNA DSB, as evaluated by the comet assay. This was supported by a hypersensitive phenotype to Top2 poisons of Ku80- and DNA-PKcs- defective Chinese hamster cell lines. We also showed that Rad51 protein levels, Rad51 foci formation and sister chromatid exchanges were increased in human cells following Top2-mediated DNA damage. In support, BRCA2- and Rad51C- defective Chinese hamster cells displayed hypersensitivity to Top2 poisons. The analysis by immunofluorescence of the DNA DSB repair response in synchronized human cell cultures revealed activation of DNA-PKcs throughout the cell cycle and Rad51 foci formation in S and late S/G2 cells. Additionally, we found an increase of DNA-PKcs-mediated residual repair events, but not Rad51 residual foci, into micronucleated and apoptotic cells. Therefore, we conclude that in human cells both NHEJ and HR are required, with cell cycle stage specificity, for the repair of Top2-mediated reversible DNA damage. Moreover, NHEJ-mediated residual repair events are more frequently associated to irreversibly damaged cells

    Dietary phytochemicals, HDAC inhibition, and DNA damage/repair defects in cancer cells

    Get PDF
    Genomic instability is a common feature of cancer etiology. This provides an avenue for therapeutic intervention, since cancer cells are more susceptible than normal cells to DNA damaging agents. However, there is growing evidence that the epigenetic mechanisms that impact DNA methylation and histone status also contribute to genomic instability. The DNA damage response, for example, is modulated by the acetylation status of histone and non-histone proteins, and by the opposing activities of histone acetyltransferase and histone deacetylase (HDAC) enzymes. Many HDACs overexpressed in cancer cells have been implicated in protecting such cells from genotoxic insults. Thus, HDAC inhibitors, in addition to unsilencing tumor suppressor genes, also can silence DNA repair pathways, inactivate non-histone proteins that are required for DNA stability, and induce reactive oxygen species and DNA double-strand breaks. This review summarizes how dietary phytochemicals that affect the epigenome also can trigger DNA damage and repair mechanisms. Where such data is available, examples are cited from studies in vitro and in vivo of polyphenols, organosulfur/organoselenium compounds, indoles, sesquiterpene lactones, and miscellaneous agents such as anacardic acid. Finally, by virtue of their genetic and epigenetic mechanisms, cancer chemopreventive agents are being redefined as chemo- or radio-sensitizers. A sustained DNA damage response coupled with insufficient repair may be a pivotal mechanism for apoptosis induction in cancer cells exposed to dietary phytochemicals. Future research, including appropriate clinical investigation, should clarify these emerging concepts in the context of both genetic and epigenetic mechanisms dysregulated in cancer, and the pros and cons of specific dietary intervention strategies
