Ask ChatGPT about the research

Prenatal detection of congenital heart disease is possible from the 16th week of pregnancy. the ideal time being the Midtrimester ,when the most cardiac abnormalities can be detected ,where all routine cross sectional views are easily obtainable. To evaluate the detection and accuracy of fetal echocardiography for congenital heart defects among high risk pregnancies.

Research summary
تتناول هذه الدراسة دور تخطيط صدى القلب الجنيني في تشخيص العيوب القلبية الولادية أثناء الحياة الرحمية. تم إجراء تصوير وتخطيط صدى القلب الجنيني بشكل استباقي عند 300 حامل في مستشفى الأطفال الجامعي بين مارس 2007 ومارس 2011، حيث تراوح العمر الحملي بين 20-38 أسبوعًا. أظهرت النتائج أن وجود قصة عائلية إيجابية لعيب قلبي ولادي شكل نحو نصف الحالات، بينما شكلت الحالات المحولة من الطبيب المولد نحو 36%. تم تشخيص العيوب القلبية الولادية في 15 حالة بنسبة 5%، وتم تأكيد التشخيص بعد الولادة. تم إنهاء الحمل في 5 حالات، وحدث موت عفوي للجنين في حالة واحدة، وحدثت الوفاة في حالتين بعد الولادة. تشير الدراسة إلى أن تخطيط صدى القلب الجنيني يمكن أن يكشف معظم العيوب القلبية الولادية واضطرابات النظم الجنينية، مما يوفر الفرصة لوضع استراتيجية مثالية للتدبير أثناء الحمل وبعد الولادة، خاصة في الحمول عالية الخطورة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة في مجال تشخيص العيوب القلبية الولادية أثناء الحياة الرحمية، حيث تقدم بيانات قيمة حول فعالية ودقة تخطيط صدى القلب الجنيني. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، العينة المستخدمة في الدراسة قد تكون محدودة من حيث الحجم والتنوع الجغرافي، مما قد يؤثر على تعميم النتائج. ثانياً، لم تتناول الدراسة بشكل كافٍ العوامل النفسية والاجتماعية التي قد تؤثر على قرار إنهاء الحمل أو استمراره بعد اكتشاف العيوب القلبية. وأخيراً، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت متابعة طويلة الأمد للأطفال الذين تم تشخيصهم بعيوب قلبية ولادية بعد الولادة، لتقييم تأثير التدخلات الطبية على جودة حياتهم.

Background: longitudinal and radial systolic function are weakened by cardiac diseases and longitudinal one is weakened first. Assessment of left ventricular LV systolic function is important in management and prognosis of cardiac diseases. Mitral annular displacement MAD is used to assess LV longitudinal and global systolic function. Objectives: To validate the accuracy of MAD assessed by Doppler tissue imaging DTI and m-mode echocardiography MME as a surrogate for determination of LV systolic function in pationts with ischemic heart disease and/or heart failure, and maybe easy and fast way instead of conventional echocardiography assessment of LV function. This way permits to study the function of LV longitudinal cardiac fibers function while the conventional ways of echocardiography assesses the circumferential shortening. Patients and methods: We studied a series of 96 patients (men and women) with (ischemic heart diseases,heart failure) divided into three age groups and compared with another 59 healthy age matched volunteers as a control group. We selected subjects from AL ASSAD hospital /LATAKIA over the year 2014. A medical history, whole medical examination, ECG, conventional echocardiography were made to each subject. Ejection fraction EF of LV, Doppler recording of the mitral inflow, MME and pulse wave Doppler tissue imaging PW DTI data (from each four sites of mitral annulus, anterior, septal, lateral and inferior) were obtained. Mean peak systolic velocity (S wave), mean annular early diastolic velocity (e') by PW DTI and mean mitral annular displacement (MAD) by MME were calculated by averaging of values measured at each annular site. Results: MAD correlate well with LV EF, mean MAD < 11.275 mm determined by MME has 85% sensitivity and 87.8% specificity and 85.8% accuracy for detection of LV EF < 50%, Mad was low in patients with infarctions and lower in pationts with heart failure. Conclusion: Mean MAD connect with a positive relationship with LV EF and can detect the abnormal systolic motion on the long axis. That means the ability to detect the ischemia in early stages.
Heart disease is the leading cause of death in the world over the past 10 years. Researchers have been using several data mining techniques to help health care professionals in the diagnosis of heart disease. Decision Tree is one of the successful d ata mining techniques used. However, most research has applied J4.8 Decision Tree, based on Gain Ratio and binary discretization. Gini Index and Information Gain are two other successful types of Decision Trees that are less used in the diagnosis of heart disease. Also other discretization techniques, voting method, and reduced error pruning are known to produce more accurate Decision Trees. This research investigates applying a range of techniques to different types of Decision Trees seeking better performance in heart disease diagnosis. A widely used benchmark data set is used in this research. To evaluate the performance of the alternative Decision Trees the sensitivity, specificity, and accuracy are calculated. The research proposes a model that outperforms J4.8 Decision Tree and Bagging algorithm in the diagnosis of heart disease patients.
We present here a simplified method to perform Bidirectional Glenn’s Cavo-Pulmonary Shunt (BDG) in which we use no cardiopulmonary bypass (CPB) nor an intra-operative temporary shunt, sometimes used on the belief that it lessens the developed intr a-venous congestion and pressure in the upper torso, intra-operatively. Our approach springs from the idea that acute intra-venous congestion, resulting from the application of vascular cross-clamp on the superior vena cava (SVC) during operation, is being vented through abundant and numerous anatomic venous anastomoses between the SVC system and the inferior vena cava (IVC) system. It also springs from the conception that the brain of patients with low arterial blood O2-saturation tolerates cerebral hypoxia better than the normally functioning brain. Such hypoxia may ensue from the transient low cerebral arterial blood flow, resulting in turn from the temporary intravenous cerebral congestion (and related raised pressure) following SVC clamping.
Aim of study: Evaluating the oral health status of children with congenital heart disease in comparison with the healthy children in Lattakia city. Materials and Methods: A total of 100 children aged between 5 and 12 years attending the pediatric clinic of AL-Assad Hospital-Lattakia were included. The study group was consisted of 50 children diagnosed with heart disease. The control group was consisted of 50 healthy children of the same age and gender. Dental caries, plaque, gingivitis and developmental enamel defects were assessed for each child in the two groups. Results: Mean dmft, gingivitis and plaque were significantly higher in the cardiac group as compared to the control group. Statistically, no significant differences were found in the comparison between the prevalence of developmental enamel defects and mean DMFT for the two groups. Conclusion: Children with congenital heart disease had a poor oral health compared to the healthy children, which increased the risk of susceptibility to bacteremia and development of infective endocarditis. Therefore, dental care for children with heart disease must be seriously considered at an early age when the first tooth erupts.
The present study aimed to early embryonic diagnose death in 46 bitchs. Blood samples were collected at the, 20th, 25th, 30th, 35th day after ovulation.
