Introduction: Sex estimates are generally based on the evaluation of qualitative and quantitative aspects of anatomic structures, however, the latter has better reproducibility and reliability. Objective: Aiming to evaluate the viscerocranium as a tool for sexual prediction and verify the possibility of creation of a logistic regression model for sexual prediction. Materials and Methods: 167 craniums - 100 male and 67 female between 22 and 85 years old from a Brazilian university´s Biobank - were evaluated. Results: It was observed that of the measures carried out were presented as sexually dimorphic, except for the measures of the right frontozygomatic point – right zygion; left frontozygomatic point – left zygion. Besides, it was possible to create a logistic regression model Sex = [logits/Sex = -24.5 + (0.20 * Nasion - Naso spine) + (0.18 * Right zygion - Naso spine)]. Conclusion: It was concluded that the measures of the viscerocranium present themselves as a factor of sexual dimorphism and the quantitative method developed was 81.4% accurate.

This study aims to use the logistic regression model to classify patients as infected and without cataracts. The independent variables were used to represent the gender, the age, the pressure in the right eye, the pressure in the left eye, HbA1C, and the anemia, representative variables for the study of Cataract disease affects the eyes, based on a random sample of (116) patients. The results proved that the used logistic regression model is an efficient and representative for data that shows through (Likelihood Ratio Test) and (Hosmer and Lemeshow test), and the study proved that the value of (R Square Nagelkerke=1) this means that 100% of the change in the occurred changes in the response variable explained through the Logistic regression model.

Considering authorship attribution as a classification problem we attempt to estimate the probability to find the right author for each text under study. In this paper using R we first improve the simple model for six Albanian texts, (I) increasing number of texts and number of independent variables and then compare the results taken with them of the multinomial logistic regression (II). The model was applied on a set of one hundred texts of ten different authors. For all the authors under study the average correct predicted probability is 0.918. Analyzing data from different Albanian texts, results that about 40% of their letters consist of vowels. As conclusion comparing results taken with them of (II) multinomial logistic regression model for Albanian texts has more advantages than logistic regression model.

Aim. Evaluation of the global systolic function of the right ventricle according to multislice computed tomography in patients with pulmonary embolism. Methods. 37 people aged 31 to 75 years (20 women and 17 men, mean age 55±12 years) were examined. The study group included 15 patients without clinical or instrumental signs of congenital heart disease and myocardial infarction of the left and right ventricles, with signs of pulmonary embolism according to multislice computed tomography. The control group included 22 patients. Tomographic analysis of end-diastolic volume, ejection fraction of the left and right ventricles was performed during noninvasive multislice computed tomography - coronary angiography, angiopulmonography. The study was conducted on a 64-helical computed tomography Aquillon 64 (Toshiba, Japan). Results. Analyzing group medians in patients with pulmonary embolism there was a decrease of the right ventricular ejection fraction and end-diastolic volume of the left ventricle (р

BACKGROUND In healthcare, information and knowledge needs of health care providers arise in the patient care process. However, the right information and knowledge at the right time and place to the right person is not reached so far yet. Thus, leads to miss diagnosis, wastage of medical resources and knowledge. OBJECTIVE The objective of this study was to assess knowledge sharing practice and associated factors among healthcare providers at University of Gondar comprehensive specialized hospital. METHODS Institutional based cross-sectional study design was conducted through stratified simple random sampling technique among 423 samples from February 24 up to March 27, 2020. Pretested, self administered questionnaire were used to collect the required data. Epi info version 7 and stata software version 15 were used for data entry, processing and analysis respectively. Descriptive statistics and multivariable logistic regression model were applied to describe the study objects and to assess knowledge sharing practice and its associated factors. P value ≤ 0.05 were considered as factors associated with knowledge sharing practice. RESULTS In this study, 423 respondents were participated. From those participants, the level of knowledge sharing practice among healthcare providers was 65.0% (95% CI: 60.46-69.56) with 100% response rate. In multivariable logistic regression model awareness AOR=2.44, 95% CI= [1.32-4.50], willingness AOR=1.96, 95% CI= [1.10-3.53], perceived loss of knowledge power AOR=0.192, 95% CI= [.12-.32], the availability of health information resource AOR=2.00, 95% CI= [1.56-5.38] and opportunity AOR=2.91, 95% CI= [1.71-4.95] were significantly associated with KSP. CONCLUSIONS Knowledge sharing practice of healthcare provider was 65.01% which is higher as compared with most studies conducted in Ethiopia. But, it needs further opportunity, resource allocation and supportive leadership to make it more beyond what exist right now.

Introduction: In recent years, COPD is observed as not an isolated, but an associated pathology, in particular, concurrent with metabolic syndrome. The aim of the research is to identify the differences in changes of the rheopulmonography parameters (RPG) depending on the presence of hypertrophy or atrophy of the right ventricular myocardium in patients with COPD concurrent with metabolic syndrome.. Materials and methods: We studied changes in rheopulmonography (RPG) in 145 patients with chronic obstructive pulmonary disease (COPD) concurrent with metabolic syndrome. Results: We detected precapillary hypertension of the pulmonary circulation in patients with right ventricular myocardial hypertrophy: anacrotism serration; flattened peak of the systolic wave; decreased Vcp; high placement of incisura; horizontal course of catacrotism; decreased amplitude of the systolic wave (in this case, due to a greater increase in the resistance of the blood flow in the pulmonary vessels than the decreased impact volume of the right ventricle); prolonged Q-a (in this group of patients, it depends more on hypertension of the pulmonary circulation than on the reduction of contractile function of the myocardium). In atrophy of the right ventricular myocardium, the following changes in the RPG were revealed: decreased systolic wave at its dramatic rise; prolonged Q-a (in this case, due to the weakened heart contraction); Vmax reduction (it reflects the reduction of myocardial contractility); in hypertrophy of the myocardium, Vcp., unlike RPG, does not decrease, which is explained by the decrease in the pressure of the pulmonary circulation. Conclusions: We believe that these changes in RPG allow differentiating hypertrophy and right ventricular myocardial atrophy along with established diagnostic criteria, and can be used as markers for the diagnosis and treatment of COPD concurrent with metabolic syndrome.
