خلفية البحث: مع دخول جائحة COVID-19 عامه الثالث ، من الواضح أن آثاره تمتد إلى ما بعد الجهاز التنفسي وهي مهمة سريريًا. قد يكون لهذه العواقب أيضًا تأثير على الصحة ونوعية الحياة. ربما يكون ثلث النساء قد عانين من تغيرات عابرة في أنماط الدورة الشهرية نتيجة للضغوط المرتبطة بوباء COVID-19. وقد يكون هذا التغيير ناتجًا عن التوتر والقلق. يمكن أن يكون عدم انتظام الدورة الشهرية أو غيابها مؤشرًا على انخفاض الخصوبة ، والذي يمكن أن يرتبط بحد ذاته بعدد من الحالات المزمنة ،و قد يتسبب النزيف الحاد في الإصابة بفقر الدم وله تأثير سلبي كبير على نوعية الحياة ويشكل عبئًا اجتماعيًا واقتصاديًا ضخمًا على النساء وأسرهن والخدمات الصحية والمجتمع. الاهداف : ان الهدف من هذه الدراسة هو النظر في تأثير عدوى فيروس كورونا على مستوى الهرمونات للمرأة (استراديول (E2) ، البرولاكتين (PRL) ، الهرمون المنبه للجريب (FSH) ، والهرمون اللوتيني (LH)) ، وكذلك الحالات النزيف الغزير الذي يحدث عند النساء العراقيات قبل انقطاع الطمث المصابات بفيروس كورونا لمدة شهرين إلى ستة أشهر على الأقل. المرضى وطرق العمل/ المواد وطرق العمل: اجريت هذه الدراسة البحثية في مدينة بغداد الطبية (العيادة الاستشارية) ، من تشرين الثاني (نوفمبر) 2021 إلى نيسان (أبريل) 2022. وشملت الدراسة 100 امرأة متزوجة في سن الإنجاب تتراوح أعمارهن بين 18 و 40 سنة. تم تقسيم عينة الدراسة إلى مجموعتين ، المجموعة الاولى 50 امرأة في سن الإنجاب مصابات بالنزيف الحاد بعد الإصابة بـ COVID-19 م لمدة أربعة أشهر على الأقل ، و 50 امرأة غير مصابات بالفيروس التاجي. النتائج: أظهرت نتائج هذه الدراسة ، بمقارنة متوسط ± SD للمجموعتين ، أن مستويات LH كانت ذات دلالة إحصائية عالية لدى النساء اللواتي عانين من نزيف حاد بعد عدوى COVID-19 مقارنة بالنساء غير المصابات بـ COVID-19 ، مع قيمة p 0.000. لم تكن هناك فروق ذات دلالة إحصائية في مستويات FSH بين المجموعتين. كانت مستويات PRL أعلى من الناحية الإحصائية بالنسبة للنساء اللائي عانين من نزيف كبير بعد الإصابة بـ COVID-19 مقارنة بالنساء غير المصابات بـ COVID-19 ، بقيمة p 0.003. كان E2 ذو دلالة إحصائية عالية مقارنة بالنساء اللائي عانين من نزيف مفرط بعد عدوى COVID-19 مقارنة بالنساء غير المصابات. الاستنتاجات: تشير نتائج هذه الدراسة إلى أن النساء بعد الاصابة بـ COVID-19 قد يكون لهن تأثير على أنماط الدورة الشهرية ، ولكن هذا التأثير كان مؤقتًا ويمكن أن يكون بسبب التوتر والقلق الذي يؤثر على HPA ومبايض النساء. قد يؤدي ذلك إلى اضطراب وظائف الجهاز التناسلي الأنثوي ، حيث تظهر مستويات مرتفعة من هرمونات الغدد التناسلية مثل LH و PRL و E2 وأحيانًا تؤدي إلى حالة نزيف حاد بعد الإصابة بفيروس كورونا.
Geomorphology is concerned with the topographic units that make up the Earth's surface. These take many forms, such as mountains and rivers, and include many dangers such as landslides, landslides and erosion. Many studies appeared in this field to analyze its effects and risks resulting from it, including urban studies, to determine the trends of optimal urban expansion and its geomorphological interactions. The results showed that the city of Kut originated and expanded near the course of the Tigris River and its branches, and it suffers from unbalanced urban expansion, due to the high rate of population growth, and overcrowding in housing units with the growth of urban land uses in it, which prompted the city to extend horizontally and v
... Show MoreBackground: Eucalyptus extracts and derivatives are natural substances with potent antimicrobial properties. This study investigated the in- vitro effects of non-nutritive sweeteners on the antifungal activity of alcoholic and aqueous Eucalyptus extracts against Candida albicans, a common oral pathogen. Materials and Method: Ten isolates of Candida albicans were isolated from dental students’ salivary samples. The alcoholic and aqueous extracts were prepared from fresh Eucalyptus leaves using maceration. The sensitivity of Candida albicans isolates to various concentrations of Eucalyptus extracts ranging from 50 to 250 (mg/mL) was evaluated via agar well diffusion method, while the agar streaking method was used to assess the minimum

Show MoreThis research deals with leverage and its impact on the profitability of Islamic banks in Iraq for the years (2015-2018), the research variables of leverage have been analyzed and measured as an independent variable, profitability as a dependent variable, and the research is based on a main hypothesis: there is a moral relationship of statistical significance. Between leverage and profitability at The Islamic Cooperation Bank for the period (2015-2018). The results of the research showed that there are moral (exorcist) relationships between the ratio of leverage and profitability indicators, as the higher the leverage ratio, the higher the profitability indicators. In addition, The Islamic Cooperation Bank has adopted a conservative poli

... Show MoreIn this work, two graphene oxide (GO) samples were prepared using the Hummers method with graphite (g) and KMnO4 (g) ratios of 1:3 (GO3) and 1:6 (GO6). The effect of oxidation degree on the structural, electrical, and dielectric properties of the GO samples was investigated. The structures of the GO samples were studied using various techniques, including X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDXS). XRD analysis revealed an increase in the interlayer spacing and a decrease in the number of layers of the samples with increasing oxidant content. The two GO samples have giant permittivity values of ~105 in the low-frequency

... Show MoreIraqi EFL college instructors, who supervise the teaching practice of EFL student teachers, commonly experience the inefficient teaching performance of prospective teachers. This inefficiency is usually due to their inability to make connections between the practical experience and the theoretical knowledge of TEFL. One of the reasons behind this inability may be the employment of traditional ways of training and instructing student teachers. Moreover, it is usually noticed that many Iraqi EFL student teachers have a negative attitude toward the teaching profession. They explicitly state that they would join the teaching force only if they fail to work in any other field.
