Brucellosis is a zoonosis occurring worldwide, with economic and public health impacts. Its diagnosis remains a challenge in endemic countries and basically relies on serology. The present study was carried out on two dairy cattle farms allegedly free from brucellosis, but with sporadic cases of abortion. The aim of this study was to investigate the presence of Brucella (B.) spp. in uterine discharge of seronegative cows after abortion. In farm I, B. melitensis biovar (bv) 3 was cultured from two of five cows after abortion, while in farm II, B. abortus bv 1 was cultured from three of eleven cows after abortion. These cows had been intrauterinely infected but remained seronegative until abortion and seroconverted only thereafter. Shedding of brucellae in uterine discharge of culture positive/seronegative aborting cows is a serious problem resulting in maintenance and further spread of infection. Thus, serosurveys in endemic countries have to be accompanied by molecular detection and/or culture of aborted material to close the diagnostic window and to hinder uncontrolled spread.

Background: Emergency department is an integral unit in a hospital because it serve large number of people so triage is needed to decrease overcrowding of Emergency department. Triage is defined as the process of sorting a group of patient in a hospital. The study aimed toassess emergency staff nurses' knowledge and performance regarding triage. Design: A comparative descriptive design was used in carrying out the study. Setting: Emergency departments of Ain Shams University Specialized Hospital affiliated to university hospitals and Naser institute hospital affiliated to Ministry of health and population (MOHP). Subjects: 36 nurses from Ain shams university specialized hospital who worked in emergency department and 30 nurse from Naser institute hospital who worked in emergency department. Tool: the data collection forms consisted of observational checklist to assess performance of nurses regarding triage and questionnaire to assess knowledge of nurses regarding triage. Results: the results showed that above half of the studied nurse had unsatisfactory knowledge regarding triage and more than three quarter of them had inadequate performance regarding triage. Conclusion: the studied nurse had unsatisfactory knowledge and inadequate performance regarding triage. Recommendation: developed triage nurse roles and triage process in the curriculum of nursing schools, nursing institutes and faculties of nursing, development of standards, specifications and qualifications of triage nurse by the Ministry of Health and population, developed training programs to all emergency health team personnel to determine the triage nurse qualifications, role, and how to use triage process, developed the protocols and policies of emergency department to facilitate the triage system and triage nurse work.

Over the previous decade, cardiovascular disease fatalities worldwide have risen by around 20 percent, with the majority of deaths happening in poor and middle-income nations (nearly 70 percent of all cardiovascular disease deaths). The purpose of this study was to examine the relationship between local EFT, PCFT, and PCFD with the existence and severity of coronary artery disease. Methods: In an imaging facility, researchers conducted this crosssectional single-center study. Patients who were sent for MSCT coronary angiography had either known or suspected coronary artery disease and were evaluated noninvasively. Results: There was no significant difference in male and female distribution in the non-atherosclerosis group, where men were more abundant, with a P value of 0.45. Regarding the risk factors of the individuals evaluated in our research, Except for those with a family history of atherosclerosis, we found a statistically significant rise in the risk variables high blood pressure, diabetes mellitus, smoking, and hyperlipidemia in the non-atherosclerosis group. There was no statistically significant difference between individuals in terms of coronary artery disease impacted by the procedure. Prognostic imaging biomarker MSCT may help identify coronary artery disease at an early stage as well as estimate risk.
