Authors: Grodt Jonas Adriel dos Santos , Piccinin Yvelise Giacomello , Souza Adriano Mendonça , Degenhart Larissa
Published: January 2023

Esta pesquisa objetivou verificar o agrupamento dos indicadores em três dimensões: divulgação ESG (Ambiental, Social e Governança), características da empresa e do país, por meio da análise de cluster dos cinco países europeus mais poluentes da OCDE, conforme o ranking da Global Carbon Atlas. Para tanto, utilizou-se de uma metodologia com caráter descritivo, documental e quantitativo. A amostra do estudo correspondeu a 241 empresas dos países da Alemanha, Reino Unido, Itália, França e Polônia, no período de 2010 a 2019. Para a análise dos dados, utilizou-se análise de cluster e uma análise adicional de regressão com efeitos robustos que busca avaliar os efeitos do ESG no desempenho e os impactos da moderação da alavancagem financeira nesta relação em cada país. Os resultados demonstraram que os indicadores, na análise de cluster, apresentam comportamentos diversos em cada agrupamento. Assim, verifica-se a heterogeneidade do comportamento em cada país analisado. Quanto à análise de regressão, percebe-se que a divulgação ESG afeta positivamente o retorno sobre os ativos (ROA) e o Market-to-book dos países. Além disso, o ROA acaba sendo reduzido em empresas que, embora divulguem ESG, estejam alavancadas financeiramente. Estes resultados apresentam implicações importantes para gestores e conselhos de administração das empresas, para desenvolver e divulgar iniciativas e políticas RSC/ESG adotadas pelas organizações, visto os impactos positivos no desempenho empresarial, beneficiando assim, as partes interessadas a empresa, sociedade e meio ambiente.

Published: January 2023

Back pain (BP) is a major public health problem worldwide with high prevalence and disability. In most cases are associated with degenerative spinal disease (degenerative disc disease, DDD), myofascial syndrome, facet joint syndrome, spinal spondylosis, scoliotic deformation, sacroilial joint dysfunction, lumbar stenosis and other causes. The article describes the basics of the doctor’s approach to the diagnosis of back pain, describes the main strategies of patients routing. The algorithm proposed here includes detection of dangerous conditions, verification of inflammatory rhythm of BP according to criteria ASAS 2009, revealing of persistent phenotype of the lower back pain, stratifying patients for the risk of chronic lower back pain StarT Back in mechanical rhythm; multidisciplinary approach with inclusion of the rheumatologist in specialists team, and after initial consultation the therapist gives direction to the rheumatologist, if necessary. A therapist who treats a patient with persistent BS and a high risk of chronization without symptoms of “red flags” should prescribe an magnetic resonance imaging of the spine. The detection of total lesion of the vertebral motor segments in the case of severe back pain is the basis for the diagnosis of spinal osteoarthritis and subsequent prescription of non-medicamentous and pharmacological therapy, including SYSADOA, in particular Alflutop. The developed algorithm allows to quickly diagnose spinal osteoarthritis at a young age and to suspect axial spondylitis. Presented triad of MR-traits associated with persistent phenotype pain, which will help the therapist to establish the diagnosis of spinal osteoarthritis. The algorithm clearly describes the routing of patients to related specialists (rheumatologist, neurologist, etc.) according to the identified data.
Parental Stress and Bringing up a Child with Cerebral Palsy: A Foreign Studies Review
Authors: Kim K.A. , Kadirov R.V.
Published: January 2023

Raising a child with cerebral palsy contains difficult stress, which negatively affects everyone who is involved in this process. In native psychology, this problem is described by I.U. Levchenko, V.V. Tkacheva, V.A. Vishnevsky, T.N. Volkovskaya. However, there is a lack of research on stress for people, who are raising a child with cerebral palsy. The purpose of this review is to learn about foreign studies on stress for people, who are raising children with cerebral palsy. The article describes R. Abidin's current leading model for parental stress. The connection between raising a child with cerebral palsy and parental stress is considered based on R. Abidin's model. Particularly, the results of studies describe specific aspects of parental stress: lack of knowledge on special child care, not an equal assignment for parental responsibilities, separation anxiety, parent's health problems, social isolation, and guilt. Based on the analysis, we can conclude that raising a child with cerebral palsy is associated with a higher level of stress than raising children without disabilities. This information can be used both in similar studies for a domestic sample and in active programs to reduce parental stress.
Background factors of crisis distance learning perception
Authors: Valger O. A. , Vezner I. A. , Sklyomina O. A.
Published: January 2023

Introduction. Crisis distance learning was an emergency response of higher education systems to the COVID-19 pandemic, and its elements still remain active in world universities. Literature review demonstrates that improvement of quality of offered courses does not demonstrate a stable correlation with improvement of students’ feedback.

Aim. This study aims to explore the influence of background factors on students’ per­ception of this format of education and identify and analyse the factors that predetermine the polarisation of students’ satisfaction levels as extremely high or extremely low.

Methodology and research methods. The research frame combined qualitative and quan­titative methods and included a series of semi-structured interviews with volunteers from the student which then served as a basis for an in-depth questionnaire with the sample of 115 respondents in the general population sample of 558 students. The Likert scale and qualitative content-analysis were employed to assess the level of satisfaction with the period under study and to build the tree of concepts perceived as its advantages and disadvantages. To identify the major factors that influenced the student perception, the multiple-choice questions that ad­dressed the students’ background conditions were weighed in comparison with the satisfaction level response in the general sample with the application of one-way analysis of variance (the Kruskal-Wallis criterion).

Results. The results show that there is polarisation in the student body. While the majority adapted to crisis distance education, there are two distinct minorities who consider it successful or unbearable. The background factors that influence the student perception sig­nificantly are the year of their programme, their commute patterns, their living conditions, and their employment status.

Scientific novelty. Overall perception of crisis distance learning by bachelor students re­flects the struggles that the students face outside the classroom and distinct groups of students have their reactions determined by these factors to a degree where improvement of teaching methods cannot assist. The distribution of satisfaction levels in the sample proves that crisis distance learning highlights economic inequality.

Practical significance. Administering higher education in this pandemic and the follow­ing pandemics to come should include a complex of measures aimed at compensating the back­ground factors that predetermine students’ low satisfaction levels in crisis distance education.

Rapid distribution of bacteria in wound infection and their appropriate treatment with antibiotics are crucial for health care providers. Bangladesh is vulnerable to multi-drug-registrant antibiotics due to extensive antibiotic misuse and other factors. The purpose of the present study was to see the frequency and distribution of bacteria isolated from pus and sensitivity patterns among hospitalized patients.

A cross-sectional study was carried out from June 2020 to July 2021. The pus samples were collected from the patients who visited BIHS General Hospital, Dhaka. Isolation and Identification of bacteria were made by culture and biochemical test and antibiotic susceptibility test was done by disc diffusion method.

The most common isolates were . Gram-positive bacteria were mostly resistant to Penicillin, Cefoxitin, Ampicillin, Azithromycin, Cotrimoxazole, Cefuroxime, and Cepradine antibiotics. 57.1% of and (100%) of was Methicillin-resistant, AMPC β-Lactamase producing bacteria (52.2%), and ESBL are (13.0%).

Due to the abuse of antibiotics, Methicillin-resistant AMPC β-Lactamase, ESBL are increasing day by day. Our study found that MDR bacteria is increasing rapidly and which is a major problem. Therefore, Antibiotic susceptibility pattern testing is required before the use of antibiotics, and continuous monitoring of antibiotic sensitivity is needed to minimize resistance.

Effectiveness of experiential learning in teaching Vietnamese language in primary schools: Perspectives of teachers and administrators
Authors: Le Lan-Anh Thi , Tran Trang Quynh
Published: January 2023

Experiential learning is an important component of both teaching and learning during the curriculum reform that is implemented in the new general teaching curriculum. Combining theoretical study with experiential learning allows students to maximize their knowledge and skills, which is beneficial to education in general and the teaching of the Vietnamese language in particular. The purpose of this study was to investigate the viewpoints held by educators and administrators regarding the efficiency of experiential learning in the context of the Vietnamese language classroom. One hundred fifty classroom instructors and nine principals from elementary schools around the country volunteered their time to participate in the survey. In the study, quantitative approaches were used with descriptive analysis to examine the collected data. According to the findings, the majority of educators and administrators were in complete agreement that providing students with opportunities for experiential learning helped them feel more comfortable and engaged in studying Vietnamese language. Even while there were some educators and school administrators who did not believe that experiential learning helped students become more responsible for themselves, others, and the community as a whole, the consensus was that it did. Experiential learning has been shown to be an effective method for teaching pupils the Vietnamese language, as demonstrated by the evidence presented in the current study. When designing a curriculum for a classroom, encouraging students to participate in experiential activities and programs should be a priority.
The Relationship between Students’ Sense of Belonging, Grit and Anxiety during Pandemic Times
Authors: Lattke Lynda S. , De Lorenzo Aurelia , Rabaglietti Emanuela
Published: January 2023

Covid-19 restrictions in Italy have significantly reduced the ‘in-presence’ time spent with classmates and teachers. As a result, this new way of relating to one another has challenged many students by increasing anxiety and depression. In such reality, protective factors such as sense of belonging (SB) and Grit (GR) can reduce anxiety (ANX).  Considering the pandemic context,  the scope of this study is to explore the relationship between SB/GR and ANX, as a risk factor and to understand whether the relationship between these variables changes based on students’ grade level (GL): middle school (MS) versus high school (HS). For this purpose, a total of 451 students from North/Central Italy, 71% F (M=15.07, ±2.46), of which 266 from HS, answered an online questionnaire in Spring 2021. Data was analyzed by doing a correlation analysis, difference between groups based on GL and hierarchical regression with SPSS 27. Results for the correlation analysis confirm that SB and GR are positively related; when controlling for differences in GL via t-test analysis, SB and GR are higher for MS. When measuring the SB/GR (Panorama Education, 2016) and its impact on the state of ANX (Spielberger et al., 1983) via the hierarchical regression, SB/GR decrease while ANX increases in particular for HS students.  These results highlight that anxiety has had a greater impact specially on HS students. For these reasons we encourage schools to create environments in which they find  strategies, as a community, to assist students in developing a sense of belonging and grit.
Recent Production and Marketing Scenarios of Water Chestnut (Trapa spp.) in India: A Review
Authors: Jana B.R.
Published: January 2023

Water chestnut (Trapa spp.) is an important annual, floated but rooted aquatic plant of temperate and tropical freshwater wetlands of India. The water chestnut is native to Europe, Asia and Africa and has been widely cultivated for a long time for food in Asia. It thrives best in nutrient-rich water with a pH range of 6.7 to 8.2. The plant Trapa spp. has also been recognized as analgesic, anti-inflammatory, anti-diabetic and anti-microbial. The kernels of water chestnut act as a diuretic, aphrodisiac, nutrient, appetizer, astringent, coolant, anti-diarrheal and tonic. It is an excellent source of minerals such as K, Ca and Mg, as well as carbohydrates and protein. In the creation of mixed products, many food products derived from the chestnut kernel and its flour are used. The yield per hectare is approximately 4-4.5 tones of fresh fruit and 1-1.5 tones of dry nuts. As fresh, canned fruit, dry nuts and flour, it has a very promising market in India and internationally. Fresh fruits are extremely delicious. TSS values varied from 7.0 to 9.00B. It is a very lovely and low-cost nutritious food that has the potential to manipulate the food market by making available various water chestnut mix flour items that might play an essential role in addressing malnutrition in India. This study of enumerated areas, production and marketing potential may be of immense value and great interest to researchers and academicians.

M a t e r i a l s a n d m e t h o d s . Medical and sociological research was conducted among students of one of the Institutes of the Russian State University named after A. N. Kosygin (Technology. Design. Art). The continuous sample of students was 505 people. During the study, clinical, socio-hygienic, statistical, analytical methods were used. R e s u l t s . The proportion of persons from the continuous sample (n=505) with normal body mass index was 64.8%, the proportion with underweight indicators was 23.1%, with excess body weight indicators – 12.1%, respectively. The largest proportion of persons with indicators of body weight deficiency was observed in the age group of 18–19 years – 23.5%, the smallest – in the age group of 22–23 years – 12.1% (Р˂0.05). However, the reverse trend is observed in the number of overweight people – with age, their proportion in the respective groups increases: from 9.3% in the age group of 18–19 years old to 18.2% in the group of 22–23 years old (Р˂0.05). F i n d i n g s . As a result of the study, it was found that the majority of students have normal body mass index, their share is 64.8%; the proportion of people with deviations in physical development is high – 35.2%, and almost every fourth student has a lack of body weight (their share in the sample is 23.1%,), one in eight is overweight (their share in the sample is 12, one%); the average value of BMI among the contingent of students (median) corresponding to the standard value was revealed, however, its high scatter was determined, amounting to 23.01, which indicates the need to use more accurate methods for analyzing the assessment of physical development indicators, for example, the method using regression scales.

The prevalence and increase in morbidity of the atopic dermatitis make possible to consider it to become actual and relevant in nearest future. The pilot study analyzed using the Delphi method allowed identifying the most significant areas for further detailed research and development of programs reducing the disease burden of atopic dermatitis in the country. The study showed that the Cumulative Life Course Impairment associated with this disease is mediated by its systemic nature and a complex of concomitant diseases. The social burden of the disease is primarily associated with missed opportunities of patients even after the onset of spontaneous remission due to education and socialization issues from the period of schooling. Almost all adult patients report a decrease in the quality of life and experiencing problems with communication and sports. The economic burden of the disease is associated with household spending on medicines and a decrease in income as a result of changing or losing work, primarily in families with sick children in addition to healthcare system expenditures. The COVID‑19 pandemic has led to a decrease in the volume of medical care for atopic dermatitis adult patients and also there is a possibility of developing previously unknown complications in patients with atopic dermatitis.

Influence of electron‑beam surfacing modes on thickness and uniformity of single‑layer coating when restoring parts made of titanium alloys
Authors: Pobol A. I. , Zaleski V. G.
Published: January 2023

The influence of the beam current, the distance between the beads of the clad material and the wire feeding intensity during electron‑beam (EB) surfacing of titanium alloy VT9 on the thickness and uniformity of the resulting restoring coating was investigated. As the beam current strength increases, the width of the deposited layer increases and the height decreases. The optimal distance between the beads should be considered an offset that does not exceed the width of the bead. It is possible to control the height of the deposited layer in a wide range by precise dosing of the wire feed intensity. The uniformity of surfacing is ensured by a balanced energy impact. Chemical composition of the clad layer meets the requirements of normative documents on the content of impurity gases for products from medical materials, obtained by additive technologies. The results of the study are used in the restoration of the surface of the landing gear element of aviation equipment.

On modification of eutectic cast iron graphite
Authors: Marukovich E. I. , Stetsenko V. Yu. , Stetsenko A. V.
Published: January 2023

It has been shown that elementary crystalline cells of graphite and basic products of iron modification do not correspond to the principle of structural and dimensional correspondence of Dankov –Konobeevsky. Modifying elements Al, Ca, Mg, Ba, Ce increase the phase tension melt‑graphite by binding surface‑active oxygen and sulfur. Modifying cast iron eutectic graphite is a nanostructured process in which modifying elements refine elemental graphite nanocrystals from adsorbed oxygen and sulfur atoms. This contributes to an increase in the concentration of graphite nuclei upon solidification of the cast iron melt. The modification reduces the concentration of dissolved hydrogen, which increases the effectiveness of the modifying effect. Reduced concentrations of demodifying surface‑active elements, melt degassing, increased heat removal contribute to increasing the degree of branching and compactness of graphite dendrites during iron crystallization. The strongest modifying element of eutectic cast iron graphite is magnesium.
Spatial and Temporal Distributions of Live Salt-Marsh Foraminifera in Southern New Jersey: Implications for Sea-Level Studies
Authors: Walker Jennifer S. , Khan Nicole S. , Shaw Timothy A. , Barber Donald C. , Switzer Adam D. , Horton Benjamin P.
Published: January 2023

Geological reconstructions of relative sea-level change have been greatly enhanced by continuous high-resolution records with the use of salt-marsh foraminifera due to their relationship with tidal level in modern environments and subsequent preservation of tests in sediments. A detailed understanding of how live foraminifera assemblages compare to dead or total (live + dead) assemblages and the influence of environmental variables on foraminiferal distributions is essential for their use as a proxy to reconstruct sea level. Here, we evaluated small-scale spatial and temporal (seasonal and interannual) variability of live foraminifera assemblages from four high marsh monitoring stations along a salinity gradient in southern New Jersey over three years. In addition, we measured porewater and sedimentary variables and stable carbon isotopes during each sampling period every three months. In the 184 samples, we identified 11 live agglutinated foraminifera species and four distinct clusters of live foraminifera that correspond to the stations from which they were sampled and to the dead and total assemblages. We found no clear correlation over time between variability in live assemblages and measured environmental variables; however, elevation was the primary controlling factor influencing foraminiferal distributions, with secondary influences from salinity and substrate. The consistency of foraminiferal assemblages on spatial and temporal scales and among live, dead, and total assemblages further reinforces the value of salt-marsh foraminifera as reliable sea-level indicators.
Review of Integrity Loss Detection and Quantification Due to Cracking in Cemented Wells
Authors: Alberdi-Pagola P. , Fischer G.
Published: January 2023

The loss of well integrity in oil and gas and CO2 injection wells provokes leaks that potentially pollute underground water reservoirs and the surrounding environment. The present publication reviews the existing literature investigating the loss of well integrity due to damage development in the cement sheath, focusing on qualitative and mainly quantitative information regarding cracks, effective permeability, and leak flows. Methods applied for leak detection on-site are reviewed, and the difficulties of these methods in providing quantitative results are highlighted. The outputs of laboratory experiments and computer simulations, considered essential to complement on-site measurements, are also reported. The review of the existing literature shows that for most of the damaged cement sheaths the observed crack widths range between 1 and 500 µm, the permeability ranges from 10−17 to 10−12 m2, and the leak rates range between 10 and 10 000 mL/min for gas leaks and between 1 and 1000 mL/min for oil leaks.

This paper describes the study of dissolution and mineralogical alteration caused by saline carbonated water injection (CWI) and its effects on the petrophysical properties (porosity and permeability) of limestone samples from the Mupe Member, composed of lacustrine microbialites from the Upper Jurassic, part of the Purbeck Group lower portion. These limestones are a partial analog of the Brazilian presalt Aptian carbonates, the most important oil reservoir in Brazil. These reservoirs present large amounts of CO2 that are reinjected into the formation, which given the high reactivity of carbonate rocks in the presence of carbonic acid generated by the reaction between CO2 and water, can cause damage to the rock’s pore space. To achieve the proposed objectives, four laminated/massive samples with very low permeability (<5 md) and two vuggy/microbial samples with very high permeability (>1,700 md) underwent laboratory tests carried out before, during, and after CWI, including gas porosity and permeability measurement, nuclear magnetic resonance (NMR), microcomputed tomography (micro-CT), and ion chromatography. X-ray diffraction (XRD) analysis and petrographic thin-section observations were also performed. The experimental results showed that samples with high permeability showed a small decrease in permeability, possibly indicating formation damage, while low-permeability samples presented a significant increase in permeability with little change in porosity, indicating feasibility for carbon capture and storage (CCS) in similar samples in likewise experimental conditions (20°C and 500 psi). For samples with more pore volumes injected, the pressure stabilization seems to have favored dissolution in the later injection stages, indicated by the highest output of calcium ions. In all samples occurred salt precipitation during injection, especially in the more heterogeneous rocks, presenting a possible issue.
New Formulas for the Trigonometry of Isosceles Triangles
Authors: King Noah
Published: January 2023

This paper discusses a new formula to solve for the angle of isosceles triangles given proportion of differentiated unequivalent edge length versus the always-equivalent edges. The equation is equal to the arcsine of (X/2) multiplied by two. This formula is to be called ‘isn^-1(x)’, short for inverse isosceles sine equivalent. Also discussed is the non-inverse ‘isn(x)’ which is the cyclic function which is determined to correspond as the equivalent of the classic sine formula to isosceles triangles. The formula set is clearly superior and powerful at calculating the angle and measure of any given obtuse or acute triangle of an unclassified type, as well as unifying a simplest-fit formula across all types of triangle. Also discussed are two transform approximation formulas, which help to analyze graphs and samples. Finally, other methods your author has obtained to calculate angles are discussed and disproven in their effectiveness against this article’s formulas at focus, as with any other known angle formulas.

Recently, machine learning has been applied into different major areas such as text classification, machine translation, and spam detection. The great performance of machine learning algorithms into several fields provided the humans with opportunities to tackle some of their hard jobs to be handled by machine learning systems. These tasks seem effortless for machines, and need less time as the amount of texts or spams need to be classified is huge. Hence, in his paper, we propose three different models for the task of emails spam detection. The three models are trained and validated on a public spam dataset. Experimentally, the models performed differently and it was seen that the Naïve Bayes outperformed the other machine learning algorithms in terms of accuracy and other evaluation metrics.
A novel approach to CSF pressure measurement via lumbar puncture that shortens the clinical measurement time with a high level of accuracy

Published: January 2023

Intracranial pressure (ICP) is an important parameter in clinical management and diagnosis of several neurological diseases. ICP is indirectly measured via lumbar puncture (LP) using a spinal manometer in clinical practice. In routine measurements of cerebrospinal fluid pressure (PCSF) from lumbar region, prolonged measurement times and low accuracy are of great concern. This measurement system consists of a spinal needle used for LP and a spinal manometer to measure PCSF. In this study, the spinal needle-spinal manometer combination was modelled with a first-order differential equation and a time constant (τ ) was defined as the product of the resistance to flow of the needle with the bore area of the manometer divided by the dynamic viscosity of CSF, i.e. τ = RA/ρCSF. Each needle/manometer combination had a unique constant as a predictor of the equilibrium pressure. The fluid pressure in the manometer rose in an exponential manner which was tested in a simulated environment using 22G spinal needles namely Braun-Spinocan, Pajunk-Sprotte and M.Schilling. Curve fitting of the manometer readings were obtained with regression coefficients of R2 ≥ 0,99 to determine measurement time constants. The residual differences between predicted and true values were less than 1,18 cmH2O. For a given needle/manometer combination, time required to reach equilibrium pressure was identical for all pressure levels. PCSF measured at reduced times can easily be interpolated to their equilibrium level allowing clinicians to obtain PCSF values with high accuracy within seconds. This method can be used as an indirect estimation of ICP in routine clinical practice.

Published: January 2023

Background
Mounting evidence indicates that the gut microbiome (GMB) plays an essential role in kidney stone (KS) formation. In this study, we conducted a systematic review and meta-analysis to compare the composition of gut microbiota in kidney stone patients and healthy individuals, and further understand the role of gut microbiota in nephrolithiasis;
Results
Six databases were searched to find taxonomy-based comparison studies on the GMB until September 2022. Meta-analyses were performed using RevMan 5.3 to estimate the overall relative abundance of gut microbiota in KS patients and healthy subjects. Qualitatively summarized the altered diversity, genetic functions and detection capability of gut microbiota in stone patients; Eight studies were included with 356 nephrolithiasis patients and 347 healthy subjects. The meta-analysis suggested that KS patients had a higher abundance of Bacteroides (34.95% vs 21.18%) and Escherichia (4.39% vs 1.78%, P < 0.05), and a lower abundance of Prevotella (8.51% vs 10.4%); Beta-diversity was different between the two groups in four out of the eight studies (P < 0.05). Three studies reported that ten taxa (Bacteroides, Phascolarctobacterium, Faecalibacterium, Flavobacterium, Akkermansia, Lactobacillus, P. aeruginosa, Escherichia coli, Rhodobacter and Gordonia) helped the detection of kidney stones P < 0.05). Four studies reported genes or protein families of the GMB involved in oxalate degradation, glycan synthesis, and energy metabolism were altered in patients (P < 0.05).
Conclusions
There is a characteristic gut microbiota dysbiosis in kidney stone patients. Individualized therapies like microbial supplementation, probiotic or synbiotic preparations and adjusted diet patterns based on individual gut microbial characteristics of patients may be more effective in preventing stone formation and recurrence.
Uterine Lipoleiomyoma in a Perimenopausal Woman
Authors: Santamonkunrot Pornchanit , Kantathavorn Nuttavut , Nakpalat Katanyuta
Published: January 2023

Background

Uterine lipoleiomyoma is a rare tumor of uterus. The authors reported a case of submucosal uterine lipoleiomyoma that presented with vaginal spotting. The clinical presentation, ultrasound imaging, hysteroscopy, and histopathological findings are documented in this report.

Case presentation

A 53-year-old perimenopausal woman presented to our gynecology clinic with vaginal spotting that did not correlate with her menstruation. She had experienced vaginal spotting almost every day for 2 months, but her normal menstruation had occurred 3 months previously. Pelvic examination was unremarkable. Transvaginal ultrasound showed a retroverted uterus with irregularities in the endometrial lining that were suspicious for endometrial polyps as well as an approximately 37- × 39-mm hyperechoic mass with hypoechoic borders at the anterior wall of the uterus. Both ovaries were unremarkable. Endometrial polyps and uterine leiomyoma were suspected. Endometrial sampling revealed endometrial polyps. Hysteroscopy showed a submucosal uterine mass; tissue was sent for pathology, and lipoleiomyoma was confirmed.

Conclusion

Uterine lipoleiomyoma is a rare variant of uterine leiomyoma. No previous reports have described malignant transformation. Therefore, conservative treatment is acceptable if asymptomatic. After the procedure, our patient went into a menopausal transition period and had no symptoms.
