Authors: KORAP Levent 
Published: January 2020

Döviz kurlarının uzun dönemli gelişim süreçlerinin tahmin edilmesi hem gelişmiş hem de gelişmekte ekonomilerde uygulanan politikaların etkinlik koşulları açısından belirleyici bir işleve sahip olacaktır. Bu makalede bir döviz kuru belirlenme modeli kapsamında TL / ABD doları 2005Q4-2018Q3 gözlem dönemi için incelenmeye çalışılmaktadır. Kuramsal bir yaklaşım izlenerek parasal model döviz kuru belirlenme mekanizması ortaya konmuş ve ARDL sınır testi eşbütünleşim yöntemi ile tahmin edilmiştir. Bulgular parasal döviz kurunun iktisat kuramının belirttiği temeller ile tutarlı bir şekilde eşbütünleşik bir ilişkiye sahip olduğunu belirtmektedir. Parasal döviz kuru göreceli para arzı ile pozitif bir etkileşim içerisindeyken göreceli reel gelir düzeyindeki bir artış ulusal para biriminin ABD doları karşısında değer kazanması ile sonuçlanmaktadır. Ayrıca, önsel olarak varsayıldığı gibi, parasal döviz kuruyla göreceli faiz oranı arasında negatif ve göreceli beklenen enflasyon oranı arasında pozitif bir ilişki bulunmuştur.

Published: January 2020

Aim: to characterize the function of the reproductive system in women after organ-preserving surgery for uterine myoma: hysteroresectoscopic (HRS) myomectomy and laparoscopic (LS) myomectomy.Materials and methods. Forty one patients were examined and divided into 2 groups: Group 1 – 18 patients after HRS myomectomy and Group 2 – 23 patients after LS myomectomy. The control group included 20 healthy women of reproductive age.Results. The HRS operation led to a significant decrease in the production of anti-Mullerian hormone (AMH), estradiol and progesterone, while the levels of luteinizing (LH) and follicle-stimulating (FSH) hormones increased. After myomectomy performed by the laparoscopic access, the levels of estradiol, progesterone, and AMH decreased but the levels of both LH and FSH increased so that the ratio LH/FSH remained unchanged. Almost all indices of gonadotropic and steroid hormone production became normalized over 6 months of the postoperative period.Conclusion. The main factors of unfavorable prognosis in patients with ovarian tecoma are tumor necrosis, degree of malignancy and mitotic activity.

Aim: to identify new prognostic criteria of potential preeclampsia (PE) in pregnant women after assisted reproductive technologies (ART) for timely PE prophylaxis.Materials and methods. A prospective study of 85 patients who entered the program of ART was conducted. All patients were examined for possible hemostatic abnormalities (genetic thrombophilia and chronic hypercoagulation) and also for granulocytemacrophage colony-stimulating factor (GM-CSF) in the serum during the most critical periods (4–6, 12–14, 22–24 и and 30–32 weeks) of the fetoplacental complex formation.Results. The lowest level of GM-CSF was observed in patients with hemostatic disorders. Thus, in pregnant women who later developed PE, there was a decrease in GM-CSF level below the physiological: in those diagnosed with genetic thrombophilia – by 79.4 %, and those with hypercoagulation – by 63.6 %.Conclusion. The determination of serum GM-CSF and identification of hemostatic abnormalities in pregnant women after ART has a prognostic importance for potential PE. This result is significant for the understanding of the pathogenesis of PE and also has a practical value: it allows the doctor to attribute the patient to a high risk group from the first trimester of her pregnancy and start preventive therapy rather early.
Pathogenesis of chorionic detachment and intrauterine hematomas in early pregnancy: a literature review
Authors: Sultangadzhieva Kh. G. 
Published: January 2020

Aim: to systematize scientific data on the frequency and pathogenesis of retrochorial and retroroamniotic hematomas in early pregnancy, including the recently published data.Materials and methods. We used sources from the electronic databases PubMed, Embase, eLibrary and articles in peerreviewed open access journals. The search was conducted using the keywords in Russian and English: retrochorial hematoma, retrochorial hemorrhage, subamniotic hematoma, pregnancy outcomes in subamniotic haematoma, pregnancy outcomes in subchorial haematoma, angiogenesis, embryogenesis, placentogenesis. The analysis included sources from the recent 30 years. We excluded publications on multiple pregnancies, ectopic pregnancy, and other sources that did not focus on the pathogenesis of chorionic detachment.Results. The following factors play a role in the occurrence of chorionic detachment: intrauterine malformations, bacterial/viral infection, chronic endometritis, immunological factors, maternal coagulation disorders (hemorrhagic diathesis, genetic thrombophilia, antiphospholipid syndrome, chronic forms of DIC), severe arterial hypertension, and habitual miscarriages.Conclusion. Knowledge of the pathogenetic mechanisms of chorionic detachment is necessary for a differential diagnosis and subsequent successful preservation of pregnancy.

Published: January 2020

Introduction. Most pelvic tumors originate from reproductive organs. Even using the up-to-date imaging techniques, radiologists experience difficulties in determining the source of the lesion since a wide range of tumors look similar to each other on the distorted backdrop of pelvic anatomy, large invasive formations, and an active inflammatory reaction of the pelvic peritoneum.Aim: to evaluate “pitfalls” in the preoperative noninvasive diagnosis of female pelvic tumors by applying the clinical diagnostic tools.Materials and methods. Four rare clinical cases were analyzed; all of them posed difficulties in interpreting the diagnostic examination due to their atypical characteristics. There were 2 cases of ovarian cancer, initially identified by an experienced team of radiologists as benign pelvic pathology. Also, there were fibroids with degeneration, marked proliferative activity, and a massive inflammatory reaction of the peritoneum – that was diagnosed as a malignant ovarian tumor. Tumor biopsies were examined using morphological and immunohistochemical methods (with the р16, Ki-67, p53, CD 117, S 100, CD 34 markers). Immunohistochemical (IHC) studies were performed with formalin-fixed paraffin materials using the avidin-biotin-peroxidase method. Antibodies to estrogen receptor (ER), progesterone receptor (PR), cytokeratin 7 (CK7), cytokeratin 20 (CK20) and Wilms tumor protein 1 (WT1) were also used.Results. A thorough analysis of the clinical picture and a joint multidisciplinary discussion (gynecologist, oncologist, radiologist, etc.) made it possible to avoid diagnostic errors.Conclusion. These observations demonstrate the difficulties of differential diagnosis between ovarian metastases of uterine cancer and primary multiple ovarian and uterine cancer, as well between leiomyosarcoma and uterine myoma with high mitotic activity. Obviously, the change in diagnosis calls for a change in the treatment strategy.

Aim. To evaluate the neuropsychological parameters from the main cognitive domains (neurodynamic functions, attention and short-term memory) and the brain electrical activity in patients with non-valve atrial fibrillation (AF).Methods. 21 patients with the mean age of 61 [56; 67] years with non-valve AF who were admitted to the Department of Interventional Diagnosis and Treatment at the Research Institute for Complex Issues of Cardiovascular Disease were included in the study. The control group consisted of 17 healthy individuals with the mean age of 55 [49; 62] years. All patients underwent neuropsychological screening and computerized testing of neurodynamic functions, attention and short-term memory along with electroencephalographic studies. Statistical analysis was performed using the STATISTICA 10.0 software package.Results. Mild cognitive impairment was observed in 43% of patients with non-valve AF accompanied by ischemic brain matter changes according to the findings of magnetic resonance imaging. Patients with AF had slower complex sensorimotor reaction, more errors, worse directed attention, memorization of words and meaningless syllables in comparison with healthy individuals. In addition, patients with AF and healthy subjects had differences in the fronto-occipital gradient of theta-2 rhythm. The worst neurodynamic parameters were associated with a greater power of theta rhythms predominantly in the posterior parts of the brain only in patients with AF.Conclusion. Patients with non-valve AF had cognitive deficit with impaired executive control, attention and short-term memory as well as the slowing of cortical electrical activity in comparison to healthy individuals. The data obtained in our study are beneficial for developing an individual approach to prevent the development and progression of cognitive impairment in patients with AF.

Aim. To find out the problems in children health in long-time postoperative period after cardiosurgery using the comprehensive method for creating rehabilitation program.Methods. A prospective investigation of group of children was done before (n = 88) and in a year (n = 115), in 2 years (n = 90) and in 3 years (n = 58) after the surgical correction of congenital heart defects on the base of Kuzbass cardiological center. The anamnesis, clinical and hemodynamic aspects were studied as well as the postoperative period, residual problems after the correction, social status of the family and the comprehensive assessment was done in the both groups.Results. Before the correction the most part of children had low and very low levels of physical functioning, but there was a positive dynamic right after the surgery: the most part of children had high and middle levels (13% and 44% in a year), while the amount of children with low and very low data were reduced. Nevertheless, in 3 years after the surgery the amount of children with low and very low data was increased while the hemodynamic became better. Such tendency was mentioned with all aspects of the health.Conclusion. Despite of hemodynamic normalization the quality of life with all aspects still suffers. It predicts dangers in development and quality of life in general.

Published: January 2020

Aim. Evaluation of short- and mid-term (up to one year) results of aт atrial fibrillation thoracoscopic radiofrequency ablation (TRFA) combined with left atrial appendage resection.Methods. 10 patients with persistent AF were included in the study. In 5 cases surgical ablation was performed as the primary intervention and in 5 cases surgery were preceded by two unsuccessful catheter procedures. Age of the patients was 54.4 (41; 63) years, duration of arrhythmic anamnesis – 5.6 (4.8; 6.8) years, anteroposterior size of the left atrium – 4.7 (45; 51 mm), LV ejection fraction – 63 (58; 68) %. TRFA included an isolation of right and left pulmonary veins, ablation lines along the roof and base of posterior wall of the left atrium, left atrial appendage resection.Results. In all cases of TRFA exit-block from the pulmonary veins was achieved. Among 10 procedures, a stable sinus rhythm was documented in 6 patients. In the remaining 4 patients AF was observed only in one case, and the other three demonstrated atypical atrial flutter, that given us a reason to repeat catheter procedures. In three cases of left atrial flutter, catheter ablation led to sinus rhythm restoration, and in case of AF and total sclerosis of left atrium a decision to refuse RF ablation was made. Complications were presented by a single case of bilateral phrenic nerve palsy, which required plication of the diaphragm, and two spontaneously resolved pulmonary atelectasis.Conclusion. The efficacy of atrial fibrillation thoracoscopic radiofrequency ablation during the follow-up period of one year was 90% regarding selective hybrid approach (thoracoscopic + catheter procedure). Procedure safety of TRFA was much lower than that of catheter ablation: the total number of small and big complications was 30%.

Primary outcomes included 90-day modified Rankin scale (mRS) score, first pass effect (FPE) and recanalization rate (TICI score), the combined incidence of postintervention hemorrhages and mortality at 90 days.Results. Among 12 patients (66.7% male, age 59.5 [57.5; 66.5] years) hypertension were in 100%, 61.5% had an ischemic heart disease, 53.8% was current smoking and atrial fibrillation. Median of the NIHSS scale was 13 points, mRS≥4 was in 75% of patients. In 33.3% was a tandem lesion (internal carotid artery terminus and middle cerebral artery) and 25% required stenting of the carotid artery. Good clinical outcomes (mRS≤2 at 90 days) were achieved in 77.8% (7/9) among surviving patients. The 90-day NIHSS score – 4 [1; 5]. The first pass effect and recanalization rate (TICI Scores 2b-3/3) was achieved in 50% and 91.7% of patients. The combined incidence of postintervention hemorrhages and mortality at 90 days was 33.3% and 25% respectively.Conclusion. Despite the small sample size, stent retriever mechanical thrombectomy in AIS provides satisfactory clinical results.

Background: The objective of this study was to evaluate the early and mid-term outcome of total correction of tetralogy of Fallot (TOF) done through transatrial approach avoiding ventriculotomy with or without transannular patching.Methods: Of 210 patients undergoing total correction for TOF between January 2016 and January 2019, 180 patients were operated via transatrial approach. The ventricular septal defect closure, infundibular resection and pulmonary valvotomy were performed through the right atrium. Age ranged from 12 months to 44 years (mean, 2.6 years), 104 patients were male and 76 patients were females.Results: Three patients (1.67%) died in early post-operative period. Pulmonary complications were seen in 8 (4.44%), septicemia in 1 (0.55%), low output syndrome in 2 (1.10%) and temporary arrhythmias in 6 (3.33%) patients. Reintubation was needed in 3 (1.67%) patients. Early reoperation was needed in 3 (1.67%) patients in view of post-operative bleeding. There were no mediastinal or deep sternal wound infections. None of our patient had complete heart block. There were no late deaths or late reoperations. Echocardiography before discharge did not reveal significant residual VSD in any patient. The mean right ventricular outflow tract pressure gradient was 28 mmHg (range of 20 to 44 mmHg) which decreased on follow-up echocardiography to 16 mmHg (range of 14 to 24 mmHg) at mean follow up of 23 months. None of our patient had severe pulmonary or tricuspid regurgitation or severe right ventricular dysfunction on follow up.Conclusions: Transatrial repair of TOF is associated with remarkably low morbidity and mortality in our early experience.

Published: January 2020

A decrease in groundwater level, especially shallow groundwater, occurred in the residential areas, and Padjadjaran University of Jatinangor part of Manglayang slope, a volcanic region at West Java Indonesia. This is due to an imbalance between groundwater input and extraction. This research aims to compile data on physical characteristics of rock lithology containing groundwater, and identifying various layers of groundwater carriers. Groundwater samples were taken in the aquifer system at the study area of the Manglayang volcanic region, and analyses using the composition diagram method and chemical analysis were conducted. The old volcanic deposit was found based on geological mapping, hydrogeology, electrical sounding measure, and boring in the area at the distal and media regime. The tuff deposit with pale soil, young deposit product is dominant in the area where there are lava and lava dome that reached the peak. There are also three types of lava, which is basalt augite, basalt, and andesite. Springwater was found at the 650 - 800 mdpl elevation. It has the facies Ca, Mg HCO3 (Calcium, Magnesium bicarbonate), and facies Mg HCO3 (Magnesium bicarbonate). The area has a local groundwater flow system above the elevation of 900 MSL and an intermediate groundwater flow system below elevation 900 MSL. The study found water catchment area is located in two places, which are zone in the elevation 900 to 1100 m with local flow patterns and 1379 m to 1697 m system intermediate. From these results, a zoning map can be developed based on the distribution of rocks and the sequences of rock formation. The study can also be utilized to determine the conservation zones' location based on the forms of delivery from each layer of rock.
Predicting Students’ Course Performance Based on Learners’ Characteristics via Fuzzy Modelling Approach

Published: January 2020

Frequent assessment allows instructors to ensure students have met the course learning objectives. Due to lack of instructor-student interaction, most of the assessment feedbacks and early interventions are not carried out in the large class size. This study is to proposes a new way of assessing student course performance using a fuzzy modeling approach. The typical steps in designing a fuzzy expert system include specifying the problem, determining linguistic variables, defining fuzzy sets as well as obtaining and constructing fuzzy rules is deployed. An educational expert is interviewed to define the relationship between the factors and student course performance. These steps help to determine the range of fuzzy sets and fuzzy rules in fuzzy reasoning. After the fuzzy assessing system has been built, it is used to compute the course performances of the students. The subject expert is asked to validate and verify system performance. Findings show that the developed system provides a faster and more effective way for instructors to assess the course performances of students in large class sizes. However, in this study, the system is developed based on 150 historical student data and only a total of six factors related to course performance are considered. It is expected that considering more historical student data and adding more factors as the variables help to increase the accuracy of the system.
