Authors: EDAFE EMMANUEL AUCHI , Akpa Maclean Rumokere
Published: February 2024

Introduction: The majority of cases of stenosis or occlusion of central veins are the result of prolonged use of central catheters, neoplasms or traumas. Central vein occlusion is also common among patients with cardiac devices or chronic repeated thrombi. Central venous occlusion could be severe due to engorged neck veins, thrombosis, venous hypertension and edema of the extremities. The objective of this study is to discuss endovascular management of central venous occlusion in three Nigerian patients. Methods: This is a retrospective study of patients seen in cardiac catheterization laboratory and the Vascular C-Arm of the Bayelsa Specialist Hospital and Cardiocare Multispecialty Hospital over a period of 6 years from January 2018 to December 2023. The data were extrcated from the patients’ record and the data analyzed with SPSS version 25.0 for windos. Results: There were 31 patients in the 6-year of review. There were 19 males and 12 females. The average age of patients was 64.0 ± 9.8 years. The commonest symptoms were facial swelling, upper extremity swelling and pain. The commonest etiology was use of long indwelling venous catheters. Conclusion: Central vein stenosis and its risk factors are common in Nigeria. The endovascular treatment included use of balloon and stents.

Nordic Pioneers of Biodynamic and Organic Agriculture
Authors: Paull John , Tutturen Tord
Published: February 2024

Fifty Nordic pioneers of biodynamic (BD) agriculture, and hence of organic agriculture, are identified. These individuals, from Norway (n = 23), Sweden (n = 12), Denmark (n = 10), and Finland (n = 5), joined the Experimental Circle of Anthroposophical Farmers and Gardeners in the years 1924–1946. These pioneers comprised both men (n = 35) and women (n = 14), with one member of undetermined gender. The Experimental Circle was headquartered at the Goetheanum, Dornach, Switzerland. One of these pioneers (Anna Wager-Gunnarson) attended the foundational course of biodynamic and organic agriculture, presented by Dr Rudolf Steiner (1861–1925), in eight lectures at Koberwitz (now Kobierzyce, Poland) in June 1924. The core element of the course was that agriculture was properly a biological rather than a chemical pursuit. The ‘Agriculture Course’ was subsequently issued (in German from 1926) as a subscriber-only published book to members (of the Anthroposophical Society) who joined the Experimental Circle. Each Circle member signed a non-disclosure agreement (NDA) and committed to testing the ideas of the course. A milestone was the 1938 book by Ehrenfried Pfeiffer, ‘Bio-Dynamic Farming and Gardening,’ which arguably released Experimental Circle members from their NDA. Nordic members joined progressively over the two decades following the Koberwitz course, with new memberships peaking in 1932 (n = 7), and continuing through the years of World War II (WWII). Biodynamic agriculture is still practiced in the Nordic countries of these pioneers, with Denmark presently accounting for 2,998 hectares, Sweden 873 ha, Norway 548 ha, and Finland 384 ha. The Nordic countries have developed strong organic sectors, with Sweden accounting for 610,543 ha of certified organic agriculture (which is 20.2% of its agricultural land), Finland 315,112 ha (14.4%), Denmark 299,998 (11.4%), and Norway 45,181 ha (4.6%). Iceland has no identified BD pioneers, presently no BD hectares, and 6,440 ha of organic agriculture (0.4% of total agriculture land). The identification of the 50 Nordic pioneers of the present paper provides recognition as early-adopters and invites further research on their life, legacy, and role in founding BD and organic agriculture in the region.

Authors: Acar Seda , Aktağ Işıl
Published: February 2024

The aim of this study is to find out the anticipation times of fifth-to eighth-grade students who participate and those who do not participate in school sports in volleyball, handball, and basketball in secondary schools, and also to determine whether the anticipation time varies according to gender, different speeds and sports experience of students participating in school sports. A total of 267 athletes (150 girls and 117 boys) participated in volleyball, handball, and basketball from the 5th to 8th grades of secondary schools, and a total of 214 athletes (90 girls and 124 boys) who did not participate in school sports in these branches were studied. The “Basin Anticipation Timer” device measured the anticipation time. As a result of the analysis, it was found that female students participating in school sports have better anticipation time than that of male students. The anticipation times of students participating in school sports were determined at speeds of 5 m/s and 8 eight m/s with average constant, absolute, and variable errors of (0.018, 0.044, 0.059) and (0.017, 0.041, 0.055), respectively. Even though the 8 m/s error results seem better than the 5 m/s results, no statistically significant difference was found between them.

Published: February 2024

Este estudo apresenta um diagnóstico sobre o aprendizado dos estudantes de ensino fundamental no período de 2007 a 2021, sob a perspectiva da superação das desigualdades. Analisa a evolução do percentual de estudantes que atingiram o nível adequado de aprendizado no Sistema de Avaliação da Educação Básica (Saeb), considerando as regiões, unidades federativas, localização (urbana/rural) da escola e grupos de estudantes definidos por sexo, cor/raça e nível socioeconômico. Apresenta também uma análise descritiva de um conjunto de escolas que não participam do Saeb e, portanto, não têm informações sobre o desempenho dos alunos. Essas escolas não têm Indice de Desenvolvimento da Educação Básica (Ideb) calculado, ficando invisíveis no diagnóstico da qualidade. Os resultados indicam a persistência e a ampliação das desigualdades no aprendizado entre os estudantes no País. Mostram ainda semelhanças entre o perfil das escolas sem Ideb e as escolas com baixo percentual de estudantes que atingiram o nível adequado de aprendizado. Diante dessas evidências, o estudo recomenda que o novo Plano Nacional de Educação adote metas e estratégias mais eficazes para superar as desigualdades educacionais e sugere que o monitoramento da qualidade da educação básica utilize indicadores mais abrangentes para avaliar as escolas que não fazem parte da população-alvo do Saeb e, portanto, não têm Ideb calculado.

The composition and control principles of steering electro-hydraulic machines of a simple and follower type, intended for rudder shifting of small and high-speed vessels are considered. An analysis of the functioning of existing steering gears for the specified group of vessels was carried out. Deficiencies in the work associated with the element base and composition of the control and electric drive systems of the analyzed steering machines have been formed. The features of the operation of hydraulic systems with drive electric motors of pumps made on direct current, revealed as a result of experiments, are shown. Variants of technical solutions for improving the energy performance of the electric drive are proposed. A comparative analysis of the operation of steering machines with AC and DC drives has been carried out. An assessment of steering machines operation in normal and emergency modes is given. Structural diagrams of control systems of simple and follow-up action are proposed, taking into account the operating features identified during the analysis and the requirements of the Russian classification society. The possibility of implementing an SM electric drive built using a frequency converter – asynchronous motor system powered by an alternating current network and an emergency source has been shown. Options for the implementation of electric drives for pumps of hydraulic stations with a high-voltage battery are proposed. The possibility of creating domestic installations for steering and other ship mechanisms, according to the proposed structural diagrams of control systems for hydraulic stations for high-speed ships, is shown. Recommendations are given for the construction of steering gears for high-speed vessels with a total displacement of up to 100 tons using domestic electrical equipment.

Published: February 2024

The algorithm of a complex methodology for assessing the technical condition of the cylinder piston group of a marine propulsion system is being investigated. Wear is a continuous process characteristic of all working mechanisms. Studies aimed at identifying factors contributing to the degradation of system elements of devices provide the basis for the development of preventive measures to reduce their effects. Knowledge of the technical condition of marine engine components is important for the development of measures that increase the reliability of equipment and reduce the risks of emergency situations. Some of the main approaches to modeling and evaluating the state of the cylinder-piston system of marine diesel engines are presented. To solve the problems of assessing the technical condition of the cylinder piston group during operation, classical methods of statistical data analysis are considered, methods that artificially increase the size of the data sample are proposed, machine learning methods are analyzed and the most effective for use are determined. An integrated approach is being created to study the operation process of a cylinder-piston group of diesel marine engines based on a combination of statistical methods, machine learning methods and probabilistic forecasting. A diagram of the properties of the studied parameters is illustrated for constructing a model for analyzing a cylinder-piston group system. Machine learning algorithms used to study systems are presented. The proposed technique allows, using the results of indirect measurements (data from lubrication analyses), to determine the technical condition of the engine system, in particular the cylinder piston group.

Published: February 2024

There is a growing trend among elderly people to live alone and this trend is expected to increase in the future. Social isolation and limited support can have a negative impact on the physical and mental well-being of older adults. The increasing life expectancy and expanding geriatric population necessitate the development of innovative solutions to support their health, independence, and autonomy. This article addresses the key challenges and issues confronting the elderly and analyzes various IoT technologies and solutions proposed to enhance their lives. Smart home technologies improve the quality of life and enable older adults to live independently in their own homes while their adult children are at work. This article presents a smart home model for the elderly in Kazakhstan, based on their needs, concerns, and financial capabilities. The proposed prototype will be developed using an accessible, open-source intelligent system that includes health monitoring, medication adherence monitoring, alerting family members in case of falls or deteriorating health indicators, and video surveillance. Another advantage of this system is the automation of processes such as automatic lighting control, voice command functionality, home security, and climate control. Preliminary testing of the hardware model shows promising results, with plans for continuous improvement and evaluation as it is deployed. Key criteria for its implementation include affordability, accessibility, and feasibility. Based on Kazakhstan’s unique socio-cultural and economic context, this paper proposes a sophisticated smart home model tailored to the specific needs and financial capabilities of elderly Kazakhs.
Mango (Mangifera indica L) var Banganapalli: Impact of in-situ intervention on folic acid concentration and its changes in physicochemical property
Authors: Rani Mamatha , Velumani Pratheepa , Rangarajan Jaganmohan , Hema Vincent , Rajagopal Vidyalakshmi
Published: February 2024

Fruits are a source of vitamins. Mango is one of the abundantly nutritional fruits. Vitamin B9, or folic acid, is one of the important vital amines due to its role in preventing neural deficiency. Several beneficial micro-organisms are used for the synthesis of folic acid. In this study, Lactobacillus acidophilus, Leuconostoc mesenteroides, Streptococcus thermophilus, and Saccharomyces cerevisiae were used. Saccharomyces cerevisiae synthesized folic acid as compared to other organisms. There were five different concentrations of mango pulp that were analyzed for folic acid synthesis (5%, 10%, 15%, 20%, and 30%). The initial concentration of pulp was 133.37 mg kg−1, but after fermentation with four micro-organisms it got reduced. As compared to the other three organisms, Saccharomyces cerevisiae synthesizes 17.15 mg kg−1, 30.14 mg kg−1, 28.62 mg kg−1, 21.70 mg kg−1, and 21.78 mg kg−1, respectively, at different pulp concentrations of 5%, 10%, 15, 20%, and 30%. Vitamin C increased to 320 mg as compared to the control, and there was no significant difference between the four micro-organisms. Antioxidants also showed positive results at different concentrations of pulp. There was an increase in titratable acidity and a decrease in pH recorded for the 24 h fermentation period. In this variety, the color of mango pulp slightly changes to yellow shades due to the breakdown of pigments, so this effects the *b value in between the pulp concentrations. Data supports the enrichment of folic acid, which will further support the utilization of beneficial micro-organisms in food beverages.

Experimental investigation of SRS polarization pulling in depleted pump regime for various pump SOPs
Authors: Cybulski Robert K. , Perlicki Krzysztof
Published: February 2024

This article presents an experimental investigation of polarization pulling based on stimulated Raman scattering induced by a continuous, fully polarized pump wave in an optical fibre. By means of probe wave states of polarization aggregation, degree of polarization and gain analysis, an assessment of all-optical polarization control, repolarization and amplification in a standard single mode fibre in depleted pump regime is presented. Polarization pulling is proved to be dependent on fibre length, pump power, and pump state of polarization, with respect to pump depletion effect, acting oppositely to the polarization pulling effect. Authors evaluate results aiming to obtain a configuration of stimulated Raman scattering parameters, which allows for the most effective polarization pulling, with respect to statistical stability of the process measured by standard deviation of polarization degree and polarization-dependent gain of the probe wave. The highest polarization attraction efficiency was obtained for 15 km, 0.97 W and the horizontal polarization state of the pump wave.
Investigation of Trees' Sensitivity to Drought: A Case Study in the Opole Region, Poland
Authors: Benisiewicz Barbara , Pawełczyk Sławomira , Niccoli Francesco , Kabala Jerzy Piotr , Battipaglia Giovanna
Published: February 2024

Pinus sylvestris L. is the most common tree species growing in Poland. Trees of this species are considered to be resistant to difficult meteorological conditions; however, in the past decades, many of them have died and been cut down by foresters. The measurements of the annual tree ring width can provide information on how trees respond to drought events. This study aimed to investigate the potential differences between healthy and declining trees (identified as trees to be cut down by foresters). For this purpose, we collected samples of five trees from each group and analysed them using dendrochronological and quantitative wood anatomy approaches. We measured ring width index (RWI) chronologies for healthy and declining trees and compared them with climate data. Additionally, we compared some anatomical features of trees from both groups as cell wall thickness (CWT) and lumen area (LA). The conducted analyses showed significant differences between healthy and declining trees. In particular, declining trees were characterised by lower RWI, LA and CWT values, especially in the past 20 years, and showed greater sensitivity to changes in temperature and humidity than healthy trees.

Published: February 2024

Loess-paleosol sequences (LPS) are an exceptional source of palaeoclimate data constituting an indirect record of changing environmental and climatic conditions that prevailed during loess deposition and early diagenesis. The Zaprężyn LPS (17°11′52″E, 51°14′44″N) is situated in the southern morphological edge of the Trzebnica Hills. This sequence provides an opportunity to reconstruct past climate conditions in this part of SW Poland. In this work, we used two sets of optically stimulated luminescence (OSL) dating from the Gliwice and Bayreuth laboratory to establish a chronological framework for this profile. The results of 14C accelerator mass spectrometry (AMS) dating were also used. The dating results are accompanied by detailed analyses of grain-size distribution and colour. The applied methodology allowed us to distinguish four litho-pedotratigraphic units: modern soil S0, L1LL1 loess unit, L1LL2 loess unit and fossil S1 soil. The OSL dating results indicate an unconformity representing a time interval >30 ka between the L1LL1 and L1LL2 units. This unconformity explains the lack of a L1SS1 soil unit. In Zaprężyn LPS, the presence of the ice wedge pseudomorph in L1LL2 loess unit was recorded. Ice wedge pseudomorph approves the presens the permafrost conditions during the Lower Plenivistulian in Trzebnica Hills.

Published: February 2024

The use of ventricular assist devices as bridge-to-transplantation therapy has a critical role in the management of end-stage heart failure in pediatric patients without available compatible organ donors. The HeartMate 3 is an intracorporeal centrifugal flow pump with a fully magnetically levitated motor currently approved for the management of advanced refractory left ventricular failure in pediatric patients, with positive early outcomes. We report the case of a 17-year-old adolescent girl with end-stage heart failure secondary to dilated cardiomyopathy of idiopathic etiology, with multiple failed attempts of weaning from inotropic support (PEDIMACS 3 profile), who successfully received a HeartMate 3 left ventricular assist device as bridge-to-transplantation therapy with no significant adverse events during the early follow-up period. This paper presents the first case of pediatric ventricular assist device implantation in Romania.
A Rare Case of Pyopneumopericardium Diagnosed by Coronary Angiography in a Patient Presented as STEMI
Authors: Stoica Adrian , Udroiu Cristian Alexandru , Vinereanu Dragos
Published: February 2024

Pyopneumopericardium is a rare pathology with a poor prognosis. Accurate diagnosis may be difficult and, in very rare cases, can mimic ST-elevation myocardial infarction (STEMI). We present the case of a 44-year-old man, with clinical, ECG, and ultrasound criteria of inferior STEMI. Emergency coronary angiography excluded obstructive coronary artery disease. However, a hydroaeric level image in the pericardium drew our attention. The chest computed tomography scan and Gastrografin study confirmed the diagnosis of pyopneumopericardium. An exploratory thoracotomy was performed to drain the liquid from the pericardium, without highlighting a fistulous path. The etiology of the pyopneumopericardium was detected by performing an upper endoscopy, which revealed a complex lesion suggestive for a foreign body perforation, which was treated with a covered esophageal stent. The outcome of the patient was unfavorable despite the complex treatment, with cardiac arrest and death occurring on the 14th day of hospitalization.

Authors: Samson-Bręk Izabela , Gabryszewska Marta
Published: February 2024

The calculation aimed to verify the life cycle assessment (LCA) results of the bulky waste management technology by using sensitivity analysis. Different sensitivity analyses for LCA were carried out to point out which of the tested methods gave the most reliable LCA results. The main factor that helped to find the best-fitted method was CO2 emissions. The LCA analyses were performed by IOŚ-PIB using SimaPro software based on the technology data obtained during the Urbanrec project. The sensitivity analysis was conducted twofold: the LCA analysis was carried out for different time horizons in the frame of the ReCiPe method egalitarian (E), individual (I), and hierarchic (H). In the second step, the LCA results for the ReCiPe method were compared with the LCA results for methods: CML-IA, Impact 2002+, and the Greenhouse Gas Protocol (GGP). The results of the LCA for all endpoints are sensitive to changes in the time horizon, which is reflected in the change in impact assessment methods used in calculations. The biggest differences are visible between the egalitarian and individual perspectives. In the second case of the sensitivity analysis, differences in results between the individual analytical methods used for LCAs can be observed. The obtained results show a high sensitivity of LCA results from the adopted time horizon, as well as moderate sensitivity of the carbon footprint depending on the method of analysis used.
PM2.5 emission from the coal combustion in the Polish residential sector. State and outlooks
Authors: Zasina Damian , Kargulewicz Iwona
Published: February 2024

The paper presents obtaining the average PM2.5 emission factor from coal combustion in the residential sector using (statistical) Monte Carlo simulation combined with the model proposed by [Lorenz 1999] and [Radović 1997], also applied by [Stala–Szlugaj 2011]. According to the results of laboratory experiments [Czaplicka et al. 2019; Shen 2014], the estimated amount of PM2.5 released into the air from the individually heated residential sector might be underestimated. Simulated emission factor is used for estimation of the PM2.5 emission trend for the period 1990–2018 and compared with the data provided by the official Polish emission inventory [NCEM 2020]. Due to significant changes in officially applied data (share of coal consumption and emission factor) [MCAE 2023], and to ensure the data consistency with projected fuel demand [Stala–Szlugaj 2017], and PM2.5 emissions [MSA 2019], the older data is used [NCEM 2020] in the paper. In the near future, the next substantial changes in projected fuel use are expected due to the ongoing works on the update of the National Energy and Climate Plan.

Background

The aim of the study was to investigate the diagnostic value of imaging necrosis (Imnecrosis) in grading, predict the genotype and prognosis of gliomas, and further assess tumor necrosis by dynamic contrast-enhanced MR perfusion imaging (DCE-MRI).

Patients and methods

We retrospectively included 150 patients (104 males, mean age: 46 years old) pathologically proved as adult diffuse gliomas and all diagnosis was based on the 2021 WHO central nervous system (CNS) classification. The pathological necrosis (Panecrosis) and gene mutation information were collected. All patients underwent conventional and DCE-MRI examinations and had been followed until May 31, 2021. The Imnecrosis was determined by two experienced neuroradiologists. DCE-MRI derived metric maps have been post-processed, and the mean value of each metric in the tumor parenchyma, peritumoral and contralateral area were recorded.

Results

There was a strong degree of inter-observer agreement in defining Imnecrosis (Kappa = 0.668, p < 0.001) and a strong degree of agreement between Imnecrosis and Panecrosis (Kappa = 0.767, p < 0.001). Compared to low-grade gliomas, high-grade gliomas had more Imnecrosis (85.37%, p < 0.001), and Imnecrosis significantly increased with the grade of gliomas increasing. And Imnecrosis was significantly more identified in IDH-wildtype, 1p19q-non-codeletion, and CDKN2A/B-homozygous-deletion gliomas. Using multivariate Cox regression analysis, Imnecrosis was an independent and unfavorable prognosis factor (Hazard Ratio = 2.113, p = 0.046) in gliomas. Additionally, extravascular extracellular volume fraction (ve) in tumor parenchyma derived from DCE-MRI demonstrated the highest diagnostic efficiency in identifying Panecrosis and Imnecrosis with high specificity (83.3% and 91.9%, respectively).

Conclusions

Imnecrosis can provide supplementary evidence beyond Panecrosis in grading, predicting the genotype and prognosis of gliomas, and ve in tumor parenchyma can help to predict tumor necrosis with high specificity.
Insights Into Estimation of Sand Permeability: From Empirical Relations to Microstructure-based Methods
Authors: Bodak Bartłomiej , Sobótka Maciej
Published: February 2024

This study evaluates various methods for estimating soil permeability using microtomography-derived data and compares them to the conventional laboratory approaches. Different methods, including measurement in custom-designed permeameter at micro-CT-compatible scale, empirical equations, simulated sifting, semi-theoretical equations, pore-network modeling, and lattice-Boltzmann simulations, were applied to samples of sandy soils with distinct microstructural properties. The empirical equations showed varied results, highly dependent on the method chosen. The simulated sifting method was able to adequately estimate the granulometric properties of the soil, allowing the use of empirical permeability formulations for substantially small samples. Semi-theoretical equations based on the microstructural properties presented reasonable agreement for some samples. The pore-network modeling approach demonstrated computational efficiency but lacked accuracy. The lattice-Boltzmann method required significant computational resources but did not provide substantially closer alignment with the measured hydraulic properties of some samples. None of the simulations was able to properly determine the permeability of silty and organically contaminated sand. The study highlights the complexity of permeability estimation, emphasizing the need for choosing volumes of interest, resolution of micro-CT scans, and methods that match specific soil characteristics and available computational resources.
Diagnosis of cardiac amyloidosis with the use of modern ultrasound techniques
Authors: Trubina E. V. , Surgutskaya M. S.
Published: February 2024

Amyloidosis is a systemic disease caused by accumulation of insoluble amyloid proteins in the tissues. Cardiac amyloidosis (CA) lead to a severe heart failure, which is often therapy resistant. The severity of heart failure does not correspond to the degree of decrease in systolic function of the left ventricle, since diastolic function is more impairing. Early diagnosis of cardiac amyloidosis is important due to the presence of treatment regimens for this disease nowadays. The “gold standard” for cardiac amyloidosis diagnosis is myocardial biopsy, but non-invasive diagnostic methods are also of great importance. The aim of the article is a review of the ultrasound signs of cardiac amyloidosis, including the use of modern technologies, which helps to suspect CA to provide a further examination.

Published: February 2024

Timely preoperative diagnosis of endometrioic cyst (endometrioma), as well as deep endometriosis remains relevant. The aim of the study was to assess the diagnostic value of ultrasound in patients with endometriomas and assess the combination of them with other foci of external genital endometriosis. The study based on retrospective analysis of a date of 95 patients with ultrasound signs of ovarian endometriomas, who underwent examination in MedicoProfi LLC – Borisov Medical and Diagnostic Clinic (Krasnoyarsk) during the period from January 2019 to October 2023. All of patients underwent surgery , followed by morphological evaluation. In the vast majority of cases, it was possible to detect a combination of endometriomas with one or more foci of deep endometriosis. Superficial peritoneal endometriosis and adhesions were found on surgery in all cases when endometriomas appeared isolated on ultrasound. The results of the study showed: endometriomas combined with deep endometriosis in 96.8% of cases. Thus, ultrasound detection of endometrioma is a very reliable sign of deep endometriosis presence. The “kissing ovaries” symptom in bilateral endometriomas can be considered as an absolutely reliable sign of the uterosacral ligaments endometriosis with specificity of 100% and positive predictive value of 100%. The presence of the “kissing ovaries” sign should be depicted in the conclusion of the ultrasound protocol, since it highly suggestive to obliteration of the pouch of Douglas and involvement of adjacent organs (fallopian tubes, intestines, ureters, etc.) in the endometrioid infiltrates, which is extremely important for the surgery planning, as well as in patients with infertility. There is an obvious need to introduce the extended pelvic ultrasound protocol to the diagnostic algorithm for patients with suspected endometriosis, which will more accurately describe the disease extension.

A steady increase in average maternity age at the time of first childbirth lead to a higher risk of fetal chromosomal abnormalities. The Order No. 1130n of the Ministry of Health of the Russian Federation establish the screening protocol at 11–14 weeks of gestation with assessing the followed criteria of fetal chromosomal pathology: the nuchal translucency thickness, nasal bone measurement, ductus venosus pulsatility index, tricuspid regurgitation, and heart rate. The value of non-invasive prenatal testing (NIPT) in the early prenatal diagnosis of the most common chromosomal abnormalities, as the trisomies 21, 18, 13, and monosomy X is also increasing. Additionally, numerous other fetal karyotype abnormalities can also be suspected at 11–14 weeks of gestation by revealing a number of other ultrasound signs. The article presents the literature review on additional ultrasound signs of various, both more and less common, chromosomal abnormalities. Pathological signs, abnormalities of fetal anatomy and extrafetal structures in the first trimester, which could be used as additional ultrasound signs of chromosomal pathology of various organs and systems (central nervous system and head, heart and blood vessels, urinary system, abdominal organs, fetal skeleton, as well as the placenta, umbilical cord, amniotic membranes) are described in the article. Despite the use of NIPT, including its extended panels, there remains a need to use ultrasound to detect the signs of rarer, but no less significant chromosomal pathologies, such as triploidies, mosaic trisomies, rare autosomal trisomies, duplications, and deletions.
