El-Tarabany and Hagar F. Gouda* Animal Wealth Development Department, Faculty of Veterinary Medicine, Zagazig University, 44511, Egypt Abstract Logistic regression is one of the popular methods used in genetic data analysis. That is applied to predict a categorical binary dependent variable on basis of predictor variables, and to test the probability of getting a particular value of the dependent variable that is related to the explanatory variable. The objective of this study is to highlight the crucial role of biostatistical methods in increasing the accuracy of the results in veterinary and biological practices. Statistical analysis of previously published data in the National Research Center, Dokki, Giza, Cairo, Egypt was done using SPSS version, 24 to predict hepatocellular carcinoma metastasis by knowing the genotypes, age, and gender of the patients. The genotypes and gender displayed a significant effect on metastasis (P < 0.05) while age had no significant effect on metastasis (P > 0.05). There are other types of data (animal breeding and production) which were analyzed by repeated measures ANOVA and principal component analysis (PCA). The repeated measures ANOVA is equivalent to normalized ANOVA, but for related, not independent groups. Data of this test was obtained from a study aimed to measure body weight of three breeds of rabbits at 4 time points 4th, 6th, 8th and 10th weeks of the experiment. The main effect of breed types of rabbits was significant (P < 0.05), the time (weeks) was highly significant (P < 0.001) and their interaction was also highly significant (P < 0.001). Principal component analysis (PCA) is used to reduce a large set of variables to a small set that still contains most of the information in the large set. A reduced set is easier to analyze and interpret. Data with 6 variables reduced to only 2 variables where initial eigenvalues were > 1 for two variables and their values were (2.768 and 1.147).

ABSTRACT This study aims to compare the effectiveness of endotracheal intubation with mechanical ventilation and noninvasive ventilation as the most in common methods used in management of ICU chest trauma patients. Sixty-eight patients with chest trauma aged 20–70 years were participated in this study for 2 years. The patients attended to cardiothoracic surgery department, Zagazig University Hospital. The Patients enrolled in this study were divided into 2 groups: the first one received endotracheal intubation with mechanical ventilation (MV group) (Group 1, n = 34) and the other received noninvasive ventilation (NV group) (Group 2, n = 34). All enrolled patients were monitored with clinical criteria including RR, HR, MAP and SpO2. The software SPSS was used for the statistical analysis. P value < 0.05 was considered as statistically significant. The present study resulted that the mean HH, HR, pO2, pCO2 and P/F ratio were improved in the MV group as well as in the NV group but this improvement was not significant. The use of noninvasive ventilation reduces mortality, damages, and complications as well as the length of stay in intensive care (ICU), which leads to low cost.

Egyptian Journal of Anatomy (EJA): volume 41 (1), January 2018 ABSTRACT Background: Coarctation of the aorta accounts for 6·8% of congenital heart disease, with an incidence of one in 12 000 live births . Coarctation is a heterogeneous lesion with variability in the degree and site of obstruction. This anatomical variation has an embryological reflection. Up till now, there is no sufficient data regarding the effect of this anatomical component of coarctation of the aorta on the short and term-long prognosis after its treatment (surgical or percutaneous angioplasty). This relationship has to be clarified. Aim of the work: We aim to demonstrate the relationship between the anatomical features of the aortic arch in case of aortic coarctation and the prognosis on the short and long term after its surgical or percutaneous repair. Patients and methods: We conducted a retrospective study that continued prospectively till the end of the work. The children with aortic coarctation who were repaired surgically or percutaneously by catheter-based angioplasty or stenting in the period between 12/2014 and 06/2016 were enrolled. All the descriptive data about this coarctation was collected (echocardiography, CT scan, and/or MRI). An anatomical analysis of these data with their embryological background was done. We have then classified these patients according to their anatomical features of the aortic arch. Follow-up data on short and long-term post-treatment of each anatomical class was gathered. Statistical analysis of these data was held to find out the relationship between this anatomical variation and the follow-up results. Results Thirty cases were enrolled in this study. 15 cases were treated surgically. the other 15 cases were treated interventionally using a balloon or stent. The mean age ± SD was17±12.2 months, the mean systolic blood pressure ±SD pre-treatment was180 ±25 mmHg. 16 cases have hypoplastic aortic arch.13 cases have abnormal aortic arch anatomy (5 have a common trunk of innominate and left common carotid,2 cases have hypoplastic left displaced left subclavian artery, 3 cases have separate right common carotid trunk from the aortic arch, 3cases have a gothic arch with very close aortic arch branches. We found that all cases with hypoplastic aortic arch had recurrent coarctation 6-9m after management. Cases with abnormal arch anatomy had a worse prognosis regarding the persistence of hypertension. There was a negative correlation between the distance (left common carotid and left subclavian arteries) and the duration before coarctation. Conclusion: Arch anatomy may affect the clinical prognosis of coarctation. Abnormal arch anatomy has a worse prognosis. The less the distance between the left subclavian and left common carotid, the better the prognosis and less incidence of re-coarctation. The importance of anatomical characteristics of aortic arch in aortic coarctation for the prognosis after its treatment
