Abstract: Eva B Ostenfeld1, Rune Erichsen1, Lene H Iversen1,2, Per Gandrup3, Mette N rgaard1, Jacob Jacobsen11Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus, Denmark; 2Department of Surgery P, Aarhus University Hospital, Aarhus, Denmark; 3Department of Surgery A, Aarhus University Hospital, Aalborg, DenmarkObjective: The prognosis for colon and rectal cancer has improved in Denmark over the past decades but is still poor compared with that in our neighboring countries. We conducted this population-based study to monitor recent trends in colon and rectal cancer survival in the central and northern regions of Denmark.Material and methods: Using the Danish National Registry of Patients, we identified 9412 patients with an incident diagnosis of colon cancer and 5685 patients diagnosed with rectal cancer between 1998 and 2009. We determined survival, and used Cox proportional hazard regression analysis to compare mortality over time, adjusting for age and gender. Among surgically treated patients, we computed 30-day mortality and corresponding mortality rate ratios (MRRs).Results: The annual numbers of colon and rectal cancer increased from 1998 through 2009. For colon cancer, 1-year survival improved from 65% to 70%, and 5-year survival improved from 37% to 43%. For rectal cancer, 1-year survival improved from 73% to 78%, and 5-year survival improved from 39% to 47%. Men aged 80+ showed most pronounced improvements. The 1- and 5-year adjusted MRRs decreased: for colon cancer 0.83 (95% confidence interval CI: 0.76–0.92) and 0.84 (95% CI: 0.78–0.90) respectively; for rectal cancer 0.79 (95% CI: 0.68–0.91) and 0.81 (95% CI: 0.73–0.89) respectively. The 30-day postoperative mortality after resection also declined over the study period. Compared with 1998–2000 the 30-day MRRs in 2007–2009 were 0.68 (95% CI: 0.53–0.87) for colon cancer and 0.59 (95% CI: 0.37–0.96) for rectal cancer.Conclusion: The survival after colon and rectal cancer has improved in central and northern Denmark during the 1998–2009 period, as well as the 30-day postoperative mortality.Keywords: neoplasms, survival, epidemiology, colorectal cancer

Post-conflict development in Liberia: Governance, security, capacity building and a developmental approach
EB Gariba
African Journal on Conflict Resolution , 2011,
Abstract: This article examines the causes of the Liberian Civil War of 1989–2003, and proposes policy alternatives that the current government can pursue to ensure durable peace and development. The paper argues that bad governance accounted for the conflict. Therefore, if peace, security and development are to be attained, there is a need for the current government to adopt and implement four policy options: good governance, security sector reform, a long-term development approach, and capacity building at the national and local levels. Although the new President of Liberia has taken some critical steps towards implementing some of these policies, more work needs to be done to address

Left ventricular hypertrophy in renal failure review
EB Arodiwe
Nigerian Journal of Clinical Practice , 2007,
Abstract: Renal failure is becoming increasingly common in our enironment. Advances in management like availability of dialysis and transplantation is prolonging the live of patients. As a consequence complication are increasingly being encountered. Cardiovascular complication is one of the commonest; and left ventricular hypertrophy is one of the major cardiovascular complications of end stage renal failure. It is an independent predictor of survival in patients with chronic renal failure and is present in a large number of patients entering maintenance haemodialysis. This review summarizes the occurrences of left ventricular hypertrophy, its pathomechhanism, clinical significance, evaluation and interventional strategies. This information is useful to us as we grapple with this problem.
"A Simple and Large Scale Performing Protocol for the Detection of Sarcocystis in Muscles of Some Small Mammals"
EB Kia
Iranian Journal of Public Health , 2003,
Abstract: A simple special protocol using Semichon’s acetic carmine stain was applied for examination of muscles of some small mammals, naturally infected with Sarcocystis spp. using this method, infected muscles fibers with Sarcocystis could easily be differentiated from muscle tissues. This method can be applied for screening of infected muscles with Sarcocystis cysts on large number of samples for epidemiological studies, and in slaughterhouses on frozen samples and formalin preserved samples as well as fresh tissues.
Manual correction of semi-automatic three-dimensional echocardiography is needed for right ventricular assessment in adults; validation with cardiac magnetic resonance

Abstract: 62 non-selected patients were examined with 3DE (Sonos 7500 and iE33) and with CMR (1.5T). Endocardial RV contours of 3DE-images were semi-automatically assessed and manually corrected in all patients. End-diastolic (EDV), end-systolic (ESV) volumes, stroke volume (SV) and ejection fraction (EF) were computed.53 patients (85%) had 3DE-images feasible for examination. Correlation coefficients and Bland Altman biases between 3DE with manual correction and CMR were r = 0.78, -22 ± 27 mL for EDV, r = 0.83, -7 ± 16 mL for ESV, r = 0.60, -12 ± 18 mL for SV and r = 0.60, -2 ± 8% for EF (p < 0.001 for all r-values). Without manual correction r-values were 0.77, 0.77, 0.70 and 0.49 for EDV, ESV, SV and EF, respectively (p < 0.001 for all r-values) and biases were larger for EDV, SV and EF (-32 ± 26 mL, -21 ± 15 mL and - 6 ± 9%, p ≤ 0.01 for all) compared to manual correction.Manual correction of the 3DE semi-automatic RV delineation decreases the bias and is needed for acceptable clinical accuracy. 3DE is highly feasible for visualizing the RV in an adult clinical setting.Assessment of the right ventricular volumes and function is of great importance in the diagnosis of various heart diseases e.g. pulmonary hypertension and congenital heart disease [1-3], for the choice of therapeutical strategies [4] and not least of prognostic value [5-7].Two-dimensional echocardiography (2DE) is the most commonly used clinical imaging modality in the evaluation of the right ventricle (RV). The complex geometrical structure of the RV with both a crescent shape and an outspread inflow and outflow tract requires a combination of several different scan planes for estimation of size and function with 2DE. M-Mode and tissue Doppler imaging of the free lateral wall of the RV are measurements in one point and are used as surrogates for the RV function. Hence, current echocardiographic techniques are not suitable for calculating right ventricular volumes and function accurately with a simple algor
Are there particular social determinants of health for the world’s poorest countries?
EB Eshetu, SA Woldesenbet
African Health Sciences , 2011,
Abstract: Background: The task of improving Social and Economic Determinants of Health (SEDH) imposes a significant challenge to health policy makers in both rich and poor countries. In recent years, while there has been increasing research interest and evidence on the workings of SEDHs, the vast majority of studies on this issue are from developed countries and emphasizes specific concerns of the developed nations of the world. Importantly, they may not fully explain the underlying causal factors and pathways of health inequality in the world’s poorest countries. Objective: To explore whether there are specific social determinants of health in the world’s poorest countries, and if so, how they could be better identified and researched in Africa in order to promote and support the effort that is currently being made for realizing a better health for all. Methods: Extensive literature review of existing papers on the social and economic determinants of health. Conclusion: Most of the existing studies on the social and economic determinants of health studies may not well provide adequate explanation on the historical and contemporary realties of SEDHs in the world’s poorest countries. As these factors vary from one country to another, it becomes necessary to understand country-specific conditions and design appropriate policies that take due cognisance of these country-specific circumstances. Therefore, to support the global effort to close gaps in health disparities, further research is needed in the world’s poorest countries, especially on African social determinants of health
HIV/AIDS-Related Knowledge And Attitudes Of Pregnant Women In Delta State, Nigeria
VO Awusi, EB Anyanwu
Benin Journal of Postgraduate Medicine , 2009,
Abstract: HIV/AIDS has become a global health challenge and, with no cure presently, prevention is the only available option in combating it. The aim of the study was to determine the knowledge and attitudes of pregnant women towards HIV/AIDS. A total of 200 consecutive women coming for antenatal care had a structured interview about the risk factors for HIV/AIDS. While most of the women (91%) were aware of HIV/AIDS, and that it could be transmitted sexually (95.6%) and through infected blood (57.7%), knowledge of its transmission through breast milk (36.8%) and mother-to-child (27.5%) was poor. Overall, 95.6% of the women would not want to stay in the same house with an AIDS patient and, 92.3% would not care for a relative with AIDS. It is suggested that health talks, such as during antenatal visits, should focus on all the modes of transmission, prevention and treatment of HIV/AIDS.
