Worldwide, about 3.5 billion people are affected, and 450 million are ill as a result of these infections, among whom, the majority are children. The objective of this study was to assess prevalence of intestinal parasites infection and associated risk factors among school children in Dagi primary school, ANRS, Ethiopia. Methods: Institutional-based cross-sectional study was conducted by involving 399 school children from 24 September to 19 October, 2012. Structured questionnaires were used to identify environmental, socio-demographic and behavioral factors and stool specimens were collected and examined for parasites using direct smear and formal-ether concentration technique. Data analysis was done by using SPSS version 15 statistical soft ware. Results: Eight species of intestinal parasites were identified with an overall prevalence of 77.9%. Students were infected with one or more intestinal parasites and the predominant parasite was hook worm, 94 (23.6%) followed by G. lamblia 91 (22.8%), E. histoltica 86 (21.6%) and Strongyloides 6 (1.5%). The presence of mixed parasitic infection was 106 (34.1%), double and triple infections were 97 (91.5%) and 9 (8.5%) respectively. Intestinal parasitic infection was higher in children whose fathers’ occupational status were farmers, who had unclean finger nails and who did not have the habit of wearing shoes (p parasites infection was an important public health problem among Dagi primary school children. Therefore, the local health office and other governmental and non-governmental organizations need to give attention to this serious problem of intestinal parasitic infection of school children.展开更多

The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality.RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospital mortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients (OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients (OR = 1.347 vs non-transferred, P < 0.001), emergency admissions (OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region (OR = 1.449 vs West, P < 0.001) had significantly higher odds of in-hospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death (OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure (OR = 8.246), acute kidney failure (OR = 4.359), hepatic encephalopathy (OR = 2.217) and esophageal variceal bleeding (OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites (OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders (OR = 2.823), coagulopathy (OR = 2.016), and lymphoma (OR = 1.842).CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay has remained relatively constant. Specific patient ethnicity, location, transfer status, primary diagnosis and comorbidities correlate with increased odds of TIPS in-hospital death.展开更多
