Background: Background : Patients with non-rheumatic atrial fibrillation have high risk of thromboembolism especially ischemic stroke usually arising from left atrial appendage .Transoesophageal echocardiography provides useful information for risk stratification in these patients as it detects thrombus in the left atrial or left atrial appendage. Objective : This study was conducted at Al-Kadhimiya Teaching Hospital to assess the prevalence of left atrial chamber thrombi in patients with chronic non-rheumatic atrial fibrillation using transoesophageal echocardiography and its clinical significance as well as to verify the superiority of transoesophageal over transthoracic echocardiography in the detection of these abnormalities. Type of the study: Cross sectional study.Patients and Methods : Forty (40) consecutive patients (11 female and 29 male), at a mean age of 46 ± 9 years (range 28–60) with chronic non-rheumatic Atrial fibrillation were enrolled to this prospective study between March 2006 and December 2006. Tansthoracic and transesophageal two dimensional , M- mode , Doppler, and color- flow echocardiography were obtained with a kretz diagnostic ultrasound system. Results : The prevalence of Left atrium thrombus was 12.5%, 5 patients from the total number which was 40 patients. All of them seen bytransoesophagealechocardiography and non are detected byTansthoracic echocardiography . All the left atrial thrombi were confined to the left atrial appendage (100%). Left atrial spontaneous echo contrast was detected in 10 patients 25% by transoesophageal echocardiography, but was not observed in patient bytransthoracic echocardiography. All the 5 thrombi were found in left atria were significantly associated with spontaneous echo contrast 100% (P-value <0.001), reduced left ventricle ejection fraction (p-value <0.05) , large left atrium diameter ( p-value <0.05) and low LAAV <20 cm/s (p-value <0.001) compared to those without thrombus . Conclusions : The study showed that the prevalence of left atrial thrombus and appendage is not uncommon in patients with non-rheumatic atrial fibrillation and is exclusively seen in patients with left atrial SEC. Low Left ventricle ejection fraction , large Left atrium diameter , and low Left atrial appendages velocity are significantly associated with subsequent thrombus formation , and is more sensitive in the detection of these abnormalities compared with transthoracic echocardiography
Community detection is an important and interesting topic for better understanding and analyzing complex network structures. Detecting hidden partitions in complex networks is proven to be an NP-hard problem that may not be accurately resolved using traditional methods. So it is solved using evolutionary computation methods and modeled in the literature as an optimization problem. In recent years, many researchers have directed their research efforts toward addressing the problem of community structure detection by developing different algorithms and making use of single-objective optimization methods. In this study, we have continued that research line by improving the Particle Swarm Optimization (PSO) algorithm using a

On the other side , this policy is a major obstacle to many developing countries and the reason is due to the nature of the economies of those countries because they rely mostly on one or a few economic resources, which makes them rely mostly on exports to that resource while they import most of the needs of their local market Which makes them in a spiral of underdevelopment , dependence and economic exposure, which requires them to break that cycle and the launch of economic development Perhaps one of the most important means to a

Interleukin-35 is a brand-new cytokine that belongs to the immunosuppressive and anti-inflammatory IL-12 family. β -herpesvirus that produces inflammation and stays dormant in its host for life is the human cytomegalovirus. Human herpesvirus (HCMV) has been at the core of several RA-related theories. Objective The current study looked at the association between RA and serum IL-35 levels as well as the association between RA and CMV. Patients and methods Blood samples were taken in the Baghdad Teaching Hospital and Typical Rheumatology Unit from January 2022 to Mars 2022 for the curre

Objectives: To assess nurses' attitude toward end of life phase. To find out relationships between nurses attitude and socio demographic data (age, gender, level of education, years of experience).
Methodology: A descriptive cross-sectional study design is carried out to assess the attitude on nurses concerning patient at the end of life phase at critical care units, from the period of (1nd November 2021) to (1th February 2022). A probability sample random sampling technique used. Then, the number of participants in Baquba Teaching Hospital and general al khalis hospital were determined by using rando

Show MoreThis study was conducted to detect the concentration of lead and cadmium in baby foods, (18) samples were examined, which are the most available from various local markets in the city of Baghdad (at a rate of (9) samples of baby food consisting of cereals and (9) samples of baby foods consisting of vegetables). All samples were examined using an atomic flame absorptiometry (AAS-7000), all results showed the presence of lead and cadmium and the highest concentration value of lead in baby foods consisting of cereals (1.0986) and cadmium in baby foods consisting of vegetables (0.0015) ppm. Lead exceeded 100% limitations and cadmium did not exceed that. The results reported on the risks of contamination, as the mean daily intake (g/kg/d) for

Evolutionary algorithms (EAs), as global search methods, are proven in the literature to be more successful than greedy methods in detecting protein complexes. However, the design of most of these EA-based approaches relies on the topological information of the proteins in the PPIN. Biological information, as a key resource for molecular profiles, on the other hand, acquired a little interest in the design of the components in these EA-based methods. The main aim of this paper is to redesign two operators in the EA based on the functional domain rather than the graph topological domain. The perturb

Infection with Toxoplasma may associate with miscarriage in many pregnant women due to infection. In this study, the level of lutetropic hormone (LTH), folliclestimulating hormone (FSH) and luteinizing hormone (LH) was measured in pregnant women suffering from toxoplasmosis using mini-VIDAS®technique. Results showed that pregnant women have high concentration of both LTH and FSH hormone(10.80 ± 6.53) ng/ml and (9.51 ± 2.40) μIU/ml respectively, while the concentration of LH hormone was lower than normal(4.49 ± 0.56) μIU/ml. Such finding is to suggest that infection with T. gondii is interfering with these hormones in pregnant women.
