Authors: Alansari Ekhlas Nasraldeen , Alomary Ahmed Yousif
Published: December 2022

Iraq has multiple water resources, so it urgently needs legislation to develop its river bank and benefit from its water resources. The purpose of this study is to investigate the shortcomings in the lack of development of the urban landscape of riverfronts in Iraqi cities by reviewing the legislative aspect of the laws regulating them, which are supposed to improve the quality of life for its citizens and achieve better environmental, social, economic and urban exploitation. This research was carried out using a qualitative approach, by analyzing the content of legislation and guidelines for urban landscapes for waterfronts in regional countries, finding urban design principles in them, and comparing them with the current Iraqi laws through the checklist. The results show that there are shortcomings in the Iraqi legislation for riverfronts and that it does not keep pace with the changes taking place in the world. The results were used to present proposals for the development of urban landscape legislation for the riverfront in Iraqi cities, in line with their social, economic and environmental conditions.

Authors: Kurniawan Surya , Rosjanuardi Rizky , Aswin Aswin
Published: December 2022

Justification is a set of responses or responses that a person gives when asked to provide mathematical reasons for the results he makes. Justification can be used as a social process in which mathematical knowledge is explained, and systematically verified based on ideas, definitions, and properties that apply in mathematics such as representations used to display concepts. Research on justification in mathematics education has been carried out for a long time. This study aims to evaluate mathematics justification studies from articles published after 2016 and before April 2022 from ERIC and Google Scholar Databases. The key questions in this study are how these articles are distributed based on year publication, country, participant, mathematics subject, method, and how to support mathematical justification. This study used a Systematic Literature Review (SLR) by Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines including inclusion and exclusion criteria and then the data were extracted, resulting in 30 studies to be reviewed. The result shows that by year of publication the articles fluctuation distributed, based on country no data from Africa and Australia was found in the databases, the participant is mostly preservice mathematics teachers, whereas only one publication studied in high school students, geometry is the most mathematics subject used in research since every grade contain this material, the method is frequently given by qualitative research with various approach, how to supporting mathematical justification is also discussed.

Published: December 2022

E-commerce is a new, rising phenomenon in Southeast Asian countries, and online payment methods are becoming increasingly popular on e-commerce platforms. Despite increasing investments in e-commerce platforms' online payment systems, Vietnamese consumers are still doubtful about this innovative payment alternative. This research applied the Technology Acceptance Model (TAM) to analyze the variables affecting customers' intention to make online payments on e-commerce platforms in Vietnam, a potential Southeast Asian market. In addition, the research group expanded on the primary study by adding the variables of Subjective Norms, Trust, and Risk to validate the findings of the original work in the new context. A new factor suitable for Vietnamese conditions, Payment Intermediary, was included by the authors to better explain the consumers’ attitudes and intentions toward online payments. The surveys were carried out using two methods of basic random sampling: an offline approach at offices and schools, and an online approach using social media. 521 questionnaires were collected, and 448 were considered valid and met the requirements that were initially set. SPSS 26 was used to assess the consistency and validity of all variables and test the hypotheses using a regression model. The hypothesis model was verified. The results showed that the correlation between independent and dependent variables, namely Attitude toward Use and Intention to Use, is very clear. In consumers' use of e-commerce platforms, Payment Intermediary plays a crucial role in developing their online payment attitudes and intentions.

Published: December 2022

The article is devoted to the problem of theoretical consideration of the best neuropsychological technologies for maintaining, strengthening and developing the occupational health of a specialist, particularly from the risk group of occupational diseases, nervous exhaustion, stress, neurosis and emotional burnout. Important criteria of occupational (psychological) health are considered. The concept of occupational health in the neuropsychological context is clarified. The criteria of occupational health and scientific approaches to consideration of neuropsychological technologies of occupational health development by foreign and domestic researchers are generalized. Occupational well-being is identified as the main criterion of occupational health. The role of neuropsychological prevention of burnout is indicated. Neuropsychological recommendations have been developed to ensure and maintain occupational health of specialists in the process of their professional development, in particular in the professional system “human – human”. Neuropsychological factors of occupational health are specified. It is noted that the state of occupational health may be associated with functional asymmetry of the brain, which requires development and implementation of neuropsychological programs to restore occupational health of professionals from a risk group.

Published: December 2022

The paper presents results of studying mechanical properties and shock-absorbing characteristics of the highly porous aluminum alloys and aluminum alloy cellular structures with the initial average density from 190 to 2250 kg/m3. The study is based on data from foreign publications and experimental results obtained by the authors. Diagrams of deformation are provided illustrating characteristic stages of the deformation process and compaction of the highly porous alloys and cellular structures made of the aluminum alloys. Highly porous alloys are identified, which deformation is close to the idealized. Based on the analysis of experimental data, presence of two groups of materials is shown: the first with deformation diagram without hardening at the compaction stage and the second with hardening. Basics for calculating specific and effective impact absorption energy are provided. Analogue shock absorbers are shown for characteristic stages of the deformation diagrams. Introduction of the effective impact absorption energy is proposed as a criterion to compare the shock absorbers with each other. The results obtained could be used in the development of the single shock absorbers.

A proposta se constitui em problematizar espaços sociais que encarnam e reproduzem o lugar socialmente construído da mulher atrelado às concepções de subalternização e subordinação. Diante disso, buscamos compreender como esses elementos, simultaneamente, tecem práticas e discursos desiguais, opressores e violentos, ao passo que tencionam multiplas formas de resistências cotidianas. Estes processos entrecruzam eixos estruturantes da sociedade brasileira, a saber: raça, gênero e classe social. Diante disso, apresentamos pesquisas que visam a reprodução da vida social na sociabilidade do capitalismo contemporâneo trazendo como ponto de partida produções culturais e políticas na realidade que atravessam relações de gênero. A partir das análises críticas, debatemos a construção de múltiplas resistências situadas nas trajetórias sociais de mulheres, pobres, negras e periféricas, inseridas em contextos específicos marcados pela vulnerabilidade social e diversas desigualdades.
STATUS QUO OPERANTE DO SISTEMA PENAL: um exemplo do (des) caso brasileiro na suspensão da implementação do juiz de garantias no processo penal
Authors: Salmen Ygor Nasser Salah , Souza André Peixoto de
Published: December 2022

O presente artigo aborda a questão da implementação do juiz de garantias no processo penal brasileiro que acabou sendo suspensa logo após seu advento legal por decisão do Supremo Tribunal Federal. O trabalho aborda a noção de sistema processual como base para melhor se compreender o instituto, o qual é justificado como medida que efetiva com maior ênfase a imparcialidade como princípio do processo penal. Apresenta-se e se enfrentam as razões apresentadas na decisão judicial que suspendeu a implementação da figura do juiz de garantias, concluindo-se que não foi com acerto que o Supremo Tribunal Federal decidiu nesse caso, fator esse que corrobora para a constatação de que o sistema penal opera em seu status quo, pois é dinâmico e ao mesmo tempo estático, cujo aparente paradoxo é intencional ao considerar a sua efetiva finalidade. O objetivo da pesquisa foi o de analisar a figura do juiz de garantias e as razões de sua suspensão por determinação judicial, tendo como problema o questionamento no sentido de se a inovação legislativa do juiz de garantias permite auferir que a regulamentação do instituto representa um avanço positivo do sistema penal, concluindo-se que não ocorreu tal avanço esperado justamente diante da decisão dada pelo Supremo Tribunal Federal que estagnou a implementação do instituto. A metodologia empregada foi a revisão bibliográfica com abordagem de estrutura de dados que se classifica como qualitativa. No que tange a modalidade da pesquisa, classifica-se como teórica/descritiva.

Authors: Donmez Gamze Sengul , Basak Tulay
Published: December 2022

In this descriptive study, the presence of any association between risk factors and quality of life (QOL) in patients with lower extremity varicose veins was determined using a disease-specific scale. This study included 200 patients admitted to the cardiovascular surgery polyclinic of a hospital between January and December 2018 with chronic venous insufficiency and lower extremity varicose veins. The data collection form was applied to the patients who accepted the study after appropriate information was given about the research by a face-to-face interview method. The QOL was found to be higher in the 51â€“70 age group, with a fixed standing time of less than 7 hours a day, without constipation and with one or more chronic diseases other than varicose veins. About 83.5% of the patients had used compression stockings (CS) and 40.5% of the patients had previously used complementary treatment methods. The QOL scores of the patients with lower extremity varices were found to be low. Causes of dissatisfaction of the patients when using CS include swelling of the feet and fingers, pain and numbness, itching of the wrist, firmness, wrinkles, keeping warm, gliding down the leg and not being cosmetic.

A multimodal approach to reading language-image-text combinations
Authors: Leibrandt Isabella
Published: December 2022

The project presented here is an experience report carried out in a university C1 German course and based on the reading of F.C. Delius' novel The Walk from Rostock to Syracuse. This article aims to provide suggestions for the practical application and the linking types of language-image texts. The students re-live the protagonist's escape on a sailing boat across the Baltic Sea from Eastern Germany during Germany’s separation from the West to fulfill his dream of a journey through Italy. This text lends itself to be explored in a multimodal way, as it presupposes implicit knowledge that includes certain historical and cultural contextual references. Therefore, information and extra-textual images are necessary to visualise and understand the narrative. Both the reading process and the results of the multimodal project are recorded in a reading blog. This offers a variety of possibilities for linguistic expression and acquisition as the multimodal approach provides varied resources for activity-based reading and communicative learning among peers.

Published: December 2022

Chronic suppurative otitis media (CSOM) is an infection of the middle ear cavity both partially and totally. It is characterized by ear discharge through a tympanic membrane perforation for over a period of 2 to 6 weeks. Hearing loss is the most common complication of CSOM. One of the degrees of hearing loss in tympanic membrane perforation is depending on the site of perforation, but this premise is still debatable because of pros and contras by some researchers. This study aimed to assess the degree of hearing loss in relation to the site of tympanic membrane perforation. A cross-sectional prospective study design was performed involving 43 patients of safe type CSOM who came to the Department of Otolaryngology Head and Neck Surgery from the period January 2016 to November 2018. All subjects were divided into 4 groups based on the site of perforation. There was a perforation in the posteroinferior, the posterosuperior, the anteroinferior, and the anterosuperior. A statistical analysis using Anova along with multivariate analysis was conducted. Our result showed that the most common site of tympanic membrane perforation was at the anteroinferior (30 samples, 59.8%). The highest hearing threshold was seen at posteroinferior with a mean hearing level of 37.7±2.0 dB, anteroinferior with a mean hearing level of 31.7±0.7 dB, anterosuperior with a mean hearing level 30.7±1.4 dB, and posterosuperior mean hearing level 28.9±1.5 dB. The difference was found significant with p=0.004. Posteroinferior tympanic membrane perforation had a higher number of hearing loss compared to the other sites. In conclusion, the tympanic membrane perforation site has an important role in the hearing level of conductive hearing loss in CSOM.

Background. To improve maternal and child health, it is essential to adhere to health-promoting and preventive measures. However, reliable information as well as effective tools are not easy to identify in this field. Our cross-sectional study investigated the needs and expectations of expectant and new mothers and fathers -primary users of an app supporting the first 1000 days of life. Methods. Between May and August 2022, we recruited expectant and new parents by administering a 71-item 5-point Likert scale questionnaire related to content, functionalities, and technical features of a hypothetical app. We stratified responses by sociodemographic characteristics and then performed ward hierarchical clustering. Results. The 94 women and 69 men involved in our study generally agreed with the proposed content, but expressed low interest in certain app functionalities, especially those related to interaction mechanism and interactivity. Women were generally more demanding than men, and family income declined as the needs and expectations increased. Conclusions. Our findings, resulting from the engagement of end-users, may be useful for designers and technology providers to implement mHealth solutions that, in addition to conveying reliable information, are tailored to the needs and preferences of end-users in the first 1000 days of life.
A Novel Phase-Field Based Formulation of Interface Evolution during Mechanical Compaction of Sedimentary Basins
Authors: Bhagat Kunal , Jin Zirou , Rudraraju Shiva
Published: December 2022

A novel phase-field method based numerical approach to modeling the compaction process of sedi- ments is presented. Water-logged rock or soil sediments are deposited on the water basins over time and the increasing volume of the sediment compacts under its own weight and external pressure. Coupled evolution of mass conservation, Darcy flow, and the viscoelastic constitutive response, in conjunction with the evolution of porosity and permeability, make this problem highly non-linear and involve moving boundaries. We adopt a phase-field approach to represent the moving sediment interface, and the underlying multiphasic model permits for studying compaction in dynamically evolving sediments. This approach does not necessitate a change of domain sizes as is the case of existing traditional models of sedimentation but rather treats sedimentation growth as a problem of interface motion. We first model a classical compaction problem in 1D to compare with existing results in the literature, and then extend the framework to 2D to model the compaction process taking place under the influence of gravity. The model is then extensively applied to understand the effect of the sediment initial state and the sediment material properties on the compaction process and its spatiotemporal evolution. Lastly, a strong validation of our phase-field treatment results against predictions from traditional methods of solving open boundary sediment compaction problems, and a good agreement between the conventional understanding and the numerical predictions of porosity dependence on the fluid pore pressure for various cases of geological interest, are used to demonstrate the applicability and scalability of this novel numerical framework to model more advanced sediment compaction problems and geometries.

Published: December 2022

This paper compares the effectiveness of different projections for different 360-degree videos and codecs, including AV1, HEVC, VP9, and AV. Content for 360 video is especially challenging because using codecs on reprojections magnifies video-stream errors. For this reason, we tested different projections to determine their stability over different encodings. Our results came from performance measurements using end-to-end metrics such as PSNR, SSIM and VMAF as well as subjective assessment of static viewports.
Combining contrastive and supervised learning for video super-resolution detection
Authors: Meshchaninov Viacheslav Pavlovich , Molodetskikh Ivan Andreevich , Vatolin Dmitriy Sergeevich , Voloboy Alexey Gennadievich
Published: December 2022

Upscaled video detection is a helpful tool in multimedia forensics, but it’s a challenging task that involves various upscaling and compression algorithms. There are many resolution-enhancement methods, including interpolation and deep-learning based super-resolution, and they leave unique traces. This paper proposes a new upscaled-resolution-detection method based on learning of visual representations using contrastive and cross-entropy losses. To explain how the method detects videos, the major components of our framework are systematically reviewed — in particular, it is shown that most data-augmentation approaches hinder the learning of the method. Through extensive experiments on various datasets, our method has been shown to effectively detects upscaling even in compressed videos and outperforms the state-of-theart alternatives. The code and models are publicly available at https://github.com/msu-video-group/SRDM.
The Peculiarities of Six-Minute Walk Test in Patients with Chronic Obstructive Pulmonary Disease, Some with Normal Weight and Some Overweight
Authors: Ovsyannikov Evgeniy , Budnevsky Andrey , Titova Lilia , Ivanova Anastasia , Kachur Anastasia
Published: December 2022

Background: The combination of chronic obstructive pulmonary disease (COPD) and overweight/obesity is a common clinical situation in modern healthcare. The objective of this study was to conduct a comparative analysis of exercise tolerance in normal body weight (NBW) and overweight patients with COPD in the 6MWT using the original device for cardiorespiratory analysis and a method for assessing the cardiorespiratory condition. Methods and Results: The study included 194 patients with COPD. The patients were divided into two groups. Group 1 consisted of 96 COPD patients with NBW: 77(80.21%) men and 19(19.79%) women aged 41 to 73 years (mean age of 63.33 ± 8.44 years). Group 2 consisted of 98 overweight COPD patients: 74(75.51%) men and 24(24.49%) women aged 55 to 71 (mean age of 64.84 ± 5.46 years). To assess tolerance to physical activity and to objectify the functional status of patients, the 6MWT was used and carried out according to generally accepted principles. The distance covered in 6 minutes (6MWD) was measured in meters and compared with the proper 6MWD(i). The developed device for cardiorespiratory analysis was used to obtain the most accurate 6MWT result. All patients in the study groups underwent an analysis of the composition of the body by the bioelectrical impedance method using a fat mass analyzer BC-555 (Tanita Corporation, Tokyo, Japan). The percentages of fat, water, muscle mass (MM), and bone mass were evaluated. The average value of the 6MWD/6MWD(i) ratio in COPD patients with NBW was significantly lower than in COPD patients with overweight (P=0.0121). Before the test, the study groups did not differ in the level of SpO2. However, according to the results of comparative analysis, this parameter was significantly lower in patients with NBW immediately after the 6MWT (P=0.0000), which, along with a lower value of the distance traveled as a percentage of the proper value in Group 1 patients, may indicate a lower tolerance to physical activity in COPD patients with NBW than in patients with overweight. In COPD patients with NBW, the percentage of fat and MM were significantly lower than in COPD patients with overweight (P=0.0000 in both cases). There was a direct correlation between 6MWD and body mass index (r=0.56, P=0.003) and between 6MWD and MM percentage (r=0.59, P=0.016). Conclusion: Higher exercise tolerance is found in overweight COPD patients than in COPD patients with NBW. This phenomenon can be explained to some extent by the compositional components of the body, in particular, by a significantly lower percentage of lean MM in patients with NBW.

Published: December 2022

The goal of this research was to evaluate the oral health of the children of the Roma, Ashkali, and Egyptian (RAE) community in relation to toothbrushing frequency. Methods and Results: A total of 201 children (93 boys and 108 girls) participated in this research. The decayed, missing, and filled teeth (DMFT) index of deciduous teeth and the simplified oral hygiene index (OHI-S) developed by Greene and Vermillion were evaluated in relation to toothbrushing frequency. Our research revealed an important and significant difference in toothbrushing frequency between the variables for F=3.7839 and P=0.0244. Children who brushed their teeth twice a day had a markedly lower DMFT index (3.15±3.29) than children who brushed their teeth less than once a day (4.86±3.81). Also, this group of children for P=0.02 had a markedly lower DMFT index (3.15±3.29) than children who brushed their teeth once a day (4.86±3.81). An important and significant difference was found between plaque index (PI) and toothbrushing frequency (H=7.86, P=0.02). Conclusion: Difficult economic circumstances and poor oral hygiene are the main factors causing poor oral health in this group of children.

Published: December 2022

Background: The minimum physiological need for sodium is estimated to be 200-500 mg/day (about 0.5-1.25 g of salt per day) (WHO, 2012). Many studies have shown that salt consumption is the main factor in increasing blood pressure (BP) and cardiovascular disease cases. Methods and Results: This transversal cross-sectional study was performed in Kosovo in 2019. The study included 219 people of both sexes (49.9% men and 50.2% women) aged 20–59 years. Urine was collected within 24 hours in accordance with the written instructions, and an oral explanation was provided to each research participant. Na and K in urine were analyzed using SmartLyte® autoanalyzer (Diamond Diagnostics, Holliston, Massachusetts, USA). Our results showed that the average urinary Na excretion over 24 hours in the Kosovo population was 9.52 g/day, which corresponds to a daily salt intake of 23.8 g/day. The average amount of urinary Na excreted in 24 hours was significantly higher in men (11.60 g/24h) than in women (7.46 g/24h) (P<0.001). Thus, the average amount of salt consumed by participants was 29.46g/day for men and 18.94 g/day for women. The average urinary K excretion over 24 hours in men was 2.02 g/day, while that in women was 1.61 g/day (P=0.000). The Na/K ratio was significantly higher in men (6.58) than in women (5.27) (P<0.05). Conclusion: the citizens of Kosovo consume a large amount of salt, greater than 5g/day. In Kosovo, there has yet to be a comprehensive strategy for reducing salt consumption.

Background: Acinetobacter baumannii is a pleomorphic aerobic Gram-negative bacillus that is notorious for having multidrug resistance traits. Carbapenem-resistant Acinetobacter baumannii (CRAB) is a global concern due to its ability to retain and disseminate resistance genes, which poses a threat to the spread of resistance among bacterial communities in hospital settings. The aim of our study was to evaluate the existence of the blaVIM-2 gene in carbapenem-resistant Acinetobacter baumannii clinical isolates from Sudanese hospitals. Methods and Results: Forty clinical isolates of Acinetobacter baumannii were collected from June 2021 to April 2022. All isolates of Acinetobacter baumannii were identified via BioMérieux's Vitek-2 automated system (Marcy l'Étoile, France) and evaluated for phenotypic resistance to carbapenem, using imipenem and meropenem. The enzymatic mode of resistance was assessed by the Modified Hodge test (MHT). A real-time PCR was used to detect the presence of the blaVIM-2 gene. Of 40 isolates, 32(80%) were resistant to imipenem, 4(10%) were moderately resistant, and 4(10%) were susceptible to imipenem; 24(60%) were resistant to meropenem, 10(25%) were moderately resistant, and 6(15%) were susceptible to meropenem. MHT was 70% positive with imipenem use and 55% positive with meropenem use. Real-time PCR revealed that only 30% of the samples were positive for the blaVIM-2 gene. All blaVIM-2-positive isolates were resistant to both imipenem and meropenem. Conclusion: Resistance to carbapenem poses a serious threat, denying patients treatment options. It is essential to make continuous surveillance of these strains to prevent the development of resistant strains.

The purpose of this study was to evaluate the safety of an injectable heparin-conjugated fibrin (HCF) hydrogel containing human synovium-derived mesenchymal stem cells (SDMSCs), TGF-β1, and BMP-4 after implantation into articular cartilage defect in patients with osteoarthritis (OA). The study included 15 OA patients with a mean age of 44.2±18.0 years. The median articular cartilage defect size was 4.9±2.0 cm. HCF hydrogel, containing SDMSCs and growth factors (TGF-β1 and BMP-4), was implanted into the cartilage defect using DUPLOJECT two-syringe device connected with the DUPLOTIP dual lumen cannula. Clinical and radiological outcomes were evaluated with VAS, WOMAC, KOOS, and MOCART. The clinical study results showed that implantation of HCF hydrogel with autologous SDMSCs, TGF-β1, and BMP-4 appeared to be safe and did not show severe adverse events in OA patients. The assessment of clinical outcomes after 6 months showed improvement in VAS, WOMAC, and KOOS scores in all patients. The MOCART evaluation demonstrated an enhancement of cartilage tissue repair in 73.3% of OA patients at 6 months after surgery. Thus, implantation of HCF hydrogel with SDMSCs, TGF-β1, and BMP-4 was safe and demonstrated signs of improvement in articular cartilage repair. The evaluation of the long-term safety and therapeutic efficacy of HCF hydrogel is required in a further clinical study using a larger number of OA patients.

Regeneration of damaged articular cartilage remains one of the most complex and unresolved problems in traumatology and orthopedics. In this study, we investigated whether intra-articular injection of synovium-derived mesenchymal stem cells (SD-MSCs) with low molecular weight hyaluronic acid (LMWHA) could promote the regeneration of damaged cartilage in rabbits. To answer this question, rabbits' SD-MSCs were harvested, expanded in culture, and characterized by CFU assay and a multilineage differentiation test. For in vivo study, we created a defect within the cartilage layer without destroying subchondral bone. Two weeks after the cartilage defect, SD-MSCs (2×106 cells) were suspended in 0.5% LMWHA and injected into the left knee, and hyaluronic acid (HA) solution alone was placed into the right knee. Cartilage regeneration in experimental and control groups was evaluated macroscopically and histologically at Days 30, 60, and 90. The results of the study showed an early process of cartilage regeneration in the defect area on Day 30 after intra-articular MSCs-HA injection. Histological studies revealed that cartilage defect was covered by a thin layer of spindle-shaped undifferentiated cells and proliferated chondroblasts, in contrast to a single HA injection, which did not induce cartilage regeneration. On Day 60, we observed that the size of the cartilage defect after MSCs-HA injection significantly decreased, compared to one after HA injection. On Day 90, the cartilage defect in a knee treated with MSCs-HA was fully regenerated and was similar to intact cartilage. Thus, the combined application of the MSCs, HA, and chondroinductive proteins have a high therapeutic effect on cartilage defect regeneration in rabbits.

Background: The world has changed radically because of the worldwide COVID-19 pandemic. SARS-CoV-2, a unique strain of large, enveloped single-stranded RNA viruses, that has spread around the world. The primary objective of this research was to assess the fetal growth velocity in pregnancies complicated by SARS-CoV-2 infection and those that were not. The secondary objective was to determine if SARS-CoV-2 infection may affect maternal and fetal Doppler readings. Methods and Results: A total of 250 pregnant women diagnosed with SARS-CoV-2 (Case group) were compared to 300 healthy pregnant women (Control group) in a prospective case-control study in Mosul from February 20 to October 20, 2021. Infections during pregnancy were detected and verified using the real-time reverse transcriptase-polymerase chain reaction (RT-PCR). All ultrasound exams were done from 24 to 40 weeks. Measuring parameters using Doppler ultrasonography included plasticity and resistive indices (PI, RI), as well as cerebroplacental ratio computed according to gestational age. Fetal development in utero was assessed by measuring biometric markers, such as parietal diameter, head size, belly circumference, leg length, and estimated fetal weight every four weeks. The US scans in the second and third trimester of pregnancy showed no evidence of congenital abnormalities (P=0.7047). There was a significant incidence of cesarean delivery (P=0.0000) and lower fetal activity at birth (P=0.0000) in the Case group, compared to the Control group. Anticoagulant treatment during pregnancy was not associated with an increased risk of postpartum hemorrhage in women of the Case group. Also, there were no significant differences in fetal biparietal diameter and femur length between groups in the second and third trimesters, and both fetal and maternal Doppler studies throughout the second and third (35-37 weeks) trimesters of pregnancy yielded no significant differences in the PI and RI indices.
