BACKGROUND: The aesthetics and strength of anterior porcelain layered zirconia (PLZ) crowns are mainly affected by the zirconia (Zr) coping design. There is a need for a modified design to enhance aesthetics with strength. OBJECTIVES: The purpose of this study was to compare the fracture resistance of anterior PLZ crowns having modified CAD-CAM Zr coping designs (in terms of thickness and marginal collar designs) with standard Zr copings. METHODS: Fifty PLZ crowns were fabricated and divided into two groups: Gr 1: Standard Zr Coping (SZC) (control gr) with 0.5 mm thickness (Facial-F, Mesial-M, Distal-D, incisal-I, and Palatal-P) without a collar; Gr 2: Collar Zr Coping (CZC) (test gr) with 2.5 mm collar height on M, D, P and 0.2 mm F and variable facial wall thickness. Subgroups: Gr 2a: (CZC-0.5 mm) facial wall thickness 0.5 mm; Gr 2b: (CZC-0.4 mm) facial wall thickness 0.4 mm; Gr 2c: (CZC-0.3 mm) facial wall thickness 0.3 mm; Gr 2d: (CZC-0.2 mm) facial wall thickness 0.2 mm. The fracture load was determined and analysed using One-way ANOVA and Dunnet test. RESULTS: The minimum fracture load was 927.36 ± 127.80 N observed for Gr 2c (CZC at 0.3 mm) while the maximum fracture load was 1373.61 ± 146.54 N observed for Gr 2a (CZC at 0.5 mm). A highly significant difference in mean fracture load among various Zr coping groups (p< 0.001) was determined. CONCLUSIONS: Novel Zr coping design for anterior PLZ crowns can provide better aesthetics with strength. Reducing the thickness of Zr coping in the aesthetic zone to 0.2 mm and providing a modified collar design (2.5 mm collar height on M, D, P, and 0.2 mm F) would provide strength without jeopardizing aesthetics.

Background: The aim of this correlational study was to investigate the multiple relationships between anxiety sensitivity, social support, and perception of pain with life expectancy. Methods: The statistical population consisted of all older adults in Isfahan (males and females) in spring 2016, of whom 250 individuals were selected by convenience sampling method from different places. In order to measure the variables, Hope Based on Islamic Sources, Perceived Social Support, Anxiety Sensitivity, and the Perception of Pain questionnaires were used. Data analysis was conducted by Pearson correlation and simultaneous multiple regression analysis. Results: The results indicated that there was a significant positive relationship between anxiety sensitivity, social support, and the perception of pain with life expectancy (P<0.01). Conclusion: This result implies that social protection enhancement, not only increases hope but also affects the fear of one’s anxiety observed by others, the perception of pain, and the fear of lack of cognitive control.

Background: Psychological well-being is a multidimensional concept that is typically defined as a mixture of positive affective states, such as satisfaction and functioning with optimum life efficiency. The aim of this study was to examine the relationship between weight efficacy lifestyle dimensions and perceived parental styles dimensions with psychological well-being among university students. Methods: The statistical population of this correlational study was all undergraduate and master students of Azarbaijan Shahid Madani University in the academic year 2016-2017, of whom 180 students were selected through multi-stage random cluster sampling. They were assessed by Clark’s Weight Efficacy Life Style (WEL), Grolnick’s Perceptions of Parents Scales (POPS), and Keyes & Magyar-Moe’s Psychological Well-being questionnaires. In addition, the demographic questionnaire was completed. Data were analyzed by SPSS V. 24 using descriptive statistics and simultaneous regression. Results: According to the findings of the study, there was a positive and significant relationship between weight efficacy lifestyle and its two subscales of negative emotions and physical discomfort with psychological well-being, and there was a negative and significant relationship between perceived parenting style and all its subscales with psychological well-being. However, 36% of changes in psychological well-being were predicted by physical discomfort, mother’s autonomy support, and mother’s warmth. Conclusion: Overall, the findings of this study support the role of weight efficacy lifestyle and perceived parenting styles variables in student psychological well-being.

Background: Marital adjustment has a positive effect on the physical and mental health of family members. The purpose of this study was to explain the process of marital adjustment in Iranian women. Methods: This research is based on qualitative data analysis using the grounded theory method. Theoretical and purposeful sampling was used for data collection. Sampling continued until theoretical saturation. A total of 15 women from Ahvaz participated in the semi-structured interview. Interviews were analyzed using the Strauss and Corbin comparative method. Results: By open coding, 17 primary codes, and axial coding, 9 major themes, related to marital adjustment were obtained. Marital adjustment: An incentive to maintain marital life were extracted as the central category influenced by contextual, causal, and confounding conditions. Contextual conditions include emotional bonding with parents and spouse. Causal conditions are an emphasis on self and relationship with another and how to express self in the relationship. Interfering conditions include a relationship with the main family, spouse, and social comparison. Strategies include defense mechanisms and empathy. The consequences of marital adjustment were also the sense of security and comfort. Conclusion: Marital adjustment can be considered in curing marital maladjustment and conflicts and help therapists to have a better understanding of marital dynamics.

Objective: This study aims to identify the challenges for public participation in health legislation in Iran. Materials & Methods: This is an exploratory and qualitative study. The study data were collected by using semi-structured interviews. The participants were experts in the field of health law with at least ten years of work experience. They had both experience and enough knowledge about the country’s health system. All interviews were transcribed verbatim after recording and then analyzed using thematic analysis. Results: We identified five main categories (themes) and 26 subcategories related to challenges. The main themes included legal barriers, infrastructure barriers, sociocultural barriers, people’s barriers, and legislators’ barriers. The legal barriers had three subcategories of parliament’s structure, legal requirements for participation, and facilitating laws. The infrastructure barriers had seven subcategories of the existence of mass media and communication networks, informing, ability to access to/meet the legislators, ability to categorize opinions, the possibility of electronic participation, financial resources, and structural facilities. The sociocultural barriers had three subcategories of people’s desire to participate, belief in teamwork, and social capital. Barriers related to people included eight subcategories of access to information, access to legislators, getting answers or feedback from legislators, feeling safe after participation, people’s awareness of their rights, education, ability to exchange views, and the existence of a highly-skilled expert team. Barriers related to legislators had nine subcategories of the desire to use others’ opinions, capacity to accept different opinions, party-related factors, regional factors, administrative health, education, opportunity, priorities, and motivational factors. Conclusion: Iranian citizens have several challenges to participate in health legislation. Regarding legal challenges, it is necessary to determine the participation right of citizens in the legal system. Besides, members of parliament should be educated to use the capacity of public participation. On the other hand, people should speak freely with the legislators and gain health knowledge as well.
Short-Term Association between the Introduction of 2020 Low Traffic Neighbourhoods and Street Crime, in London, UK
Authors: Goodman Anna , Laverty Anthony A. , Aldred Rachel
Published: May 2021

Between March and September 2020, 72 ‘Low Traffic Neighbourhoods’ (LTNs) were rapidly rolled out in London under emergency legislation. We examined the association between LTN implementation and street crime in October 2020 - February 2021 (‘post’), as compared to the same months in the previous two years (‘pre’). Overall crime trends in and around LTNs were more favourable than the background trend in Outer London, and similar to or slightly more favourable than the trend in Inner London. This pattern was also seen for numbers of direct attacks against the person - and this may underestimate the benefit per pedestrian, given evidence that LTN introduction is associated with increased walking.
A Vérfű-hangyaboglárka, Maculinea teleius (Lepidoptera: Lycaenidae) mátrai állományának vizsgálata és a megmentésére irányuló kísérlet

Published: May 2021

A vérfű-hangyaboglárka, Maculinea teleius (Bergsträsser, 1779) szórványosan fordul elő a Bükki Nemzeti Park Igazgatóság működési területén. Ezen belül a Mátra térségében mindössze két, egymáshoz közeli élőhelyfoltban maradt fenn a faj, Sirok határában. Ezen a két területen végeztünk jelölés-visszafogásos vizsgálatot, illetve felmértük a petézésre alkalmas őszi vérfű, Sanguisorba officinalis L. virágzatok számát. A kutatásainkat a lepkefaj repülési idejének második felében kezdtük el, miután szembesültünk az itt fennálló élőhelykezelési problémával. A két területen folyó gazdálkodás meglehetősen rapszodikus, évenként nagyon eltérő. Az utóbbi években a kisebb rétet júliusban kaszálták le, ami a vérfű-hangyaboglárka számára kedvezőtlen. Ennek következtében kritikusan lecsökkent az ottani populáció egyedszáma, a 2017-es felmérés során mindössze 6 egyedet jelöltünk meg. Ugyanebben az évben viszont kedvező időpontban történt a kaszálás, így a lepkék repülési idejében sok virágzó vérfű volt a területen (915 virág). A nagyobb élőhelyfoltban ennek éppen az ellenkezője történt, a 2017 előtti években a megfelelő időpontban történő kaszálások következtében stabil állománya volt a lep- kének, így a felmérés során 31 egyedet jelöltünk meg. 2017-ben viszont július elején kaszálták le a gyepet, így a lepkék szaporodási idejében alig volt petézésre alkalmas virágzó vérfű a területen (mindössze 76 virág). A faj mátrai állományának megőrzése érdekében lepke-áttelepítést végeztük. A virágzó vérfüvet alig tartalmazó élőhelyről vittünk át egyedeket az ebben bővelkedő rétre. Így tudtunk szaporodási lehetőséget biztosítani a lepkék számára. 2018-ban megismételtük a vizsgálatainkat, hogy meggyőződhessünk a sikerességünkről. A kisebb élőhelyen 22 egyed került meg jelölésre, tehát jelentősen emelkedett a populáció egyedszáma. A tápnövény virágfejeinek száma is növekedett: az előbbi területen 1198 db, az utóbbin 7018 db-ot számoltunk össze.

En diciembre del 2019, una serie de neumonías atípicas comenzaron a aparecer en Wuhan, China. Rápidamente se decidió tipificar el agente etiológico, el cual resultó ser una nueva cepa de coronavirus, el cual fue llamado 2019-nCoV, posteriormente sería renombrado a SARS-CoV-2, debido a su gran homología genética al SARS-CoV, virus causal del síndrome de estrés respiratorio agudo y una alta mortalidad durante las epidemias de 2002 y 2003. La enfermedad causada por este virus se denominó COVID-19 (Coronavirus disease 19). En marzo de 2020, la Organización Mundial de la Salud (OMS) declaró el estado de pandemia a esta emergencia sanitaria. El SARS-CoV-2 afecta primordialmente el sistema respiratorio, pero afecta a casi todos los órganos y sistemas del individuo. De igual manera, aunque los síntomas respiratorios son los más notorios, no se deben subestimar las manifestaciones extrapulmonares, ya que pueden comprometer la vida del paciente. En esta revisión se abordará principalmente la fisiopatología del SARS-CoV-2, así como la respuesta inmune conocida hasta el momento.

Sin tratamiento oportuno, las lesiones cutáneas por Streptococcus pueden poner en peligro la vida de una persona. En el caso de México hay factores para que se den estas infecciones por el incremento en el número de enfermos con diabetes mellitus tipo 2, que produce un estado de inmunosupresión en el organismo. Las vías de entrada para la bacteria pueden ser desde una tiña de los pies, un mal rasurado, hasta traumatismos graves. En el caso de S. pyogenes puede manifestarse desde una erisipela o una celulitis hasta una fascitis necrotizante o síndrome de shock tóxico estreptocóccico. Estas lesiones están relacionadas con los factores de virulencia de la bacteria que le permiten adherirse a la epidemis (fibronectin-binding, proteína M), evadir el sistema inmune (Mac-1, Mac-2, EndoS, SpeB, la cápsula, ScrpA) y comenzar un proceso de patogénesis (estreptolisina O, estreptolisina S, hialuronidasa, estreptocinasa, superantígenos). El objetivo de este trabajo es mostrar la fisiopatología de los principales factores de virulencia del Streptococo pyogenes que generan lesiones cutáneas.

Authors: Salim Muhammad Nur
Published: May 2021

ABSTRACT One of the developments in film in Indonesia is the musical genre film. This genre film experienced a post-reform high point when Sherina's Adventure Film came. This point then became the beginning of the development of musical genre films that were born in the 2000s period. One of the interesting musical films is the Javanese Opera Film by Garin Nugroho. Opera Jawa is interesting because first, Opera Jawa has received various awards and nominations at both national and international levels. Second, because this film bases its musical work on Javanese gamelan or gamelan media. This second reason is the focus of this research. The research "Rahayu Suanggah's Creativity in Garin Nugroho's Javanese Opera Film" is an attempt to reveal one of the film music creation methodologies based on her creative process with Javanese karawitan media (gamelan music). The musical concepts of the musical that were carried by Rahayu Supanggah as the music director was revealed through Rahayu Supanggah's conceptual approach in Bothekan Karawitan Garap's book (2007). The results of this study; Rahayu Supanggah uses Javanese musical nuances in composing Javanese Opera music by involving songs that are composed in various variations such as; 1) single tembang, 2) pathetan, 3) nothing, 4) palaran, and 5) arrangement of traditional pieces while the illustration music consists of 1) New Composition, 2) Illustration of Traditional Music, 3) Exploration Music. Keywords: Creativity, Music, Javanese Opera, Rahayu Supanggah  ABSTRAK Perkembangan film di Indonesia salah satunya pernah diwarnai oleh film genre musikal.

Hasil penelitian ini; Rahayu Supanggah menggunakan nuansa karawitan Jawa dalam menggarap musik Opera Jawa dengan melibatkan tembang yang digarap dalam berbagai variasi seperti; 1) tembang tunggal, 2) pathetan, 3) ada-ada, 4) palaran dan 5) aransemen gendhing tradisi sedangkan musik ilustrasi terdiri dari 1) Komposisi Baru, 2) Ilustrasi Gending Tradisi, 3) Musik Eksplorasi.Kata Kunci: Kreativitas, Musik, Opera Jawa, Rahayu Supanggah
Attualità in nefrologia pediatrica: le conoscenze di rilievo per il nefrologo dell’adulto
Authors: Edefonti Alberto , Vergori Antonio , Montini Giovanni , Emma Francesco
Published: May 2021

Examples of innovative research in pediatric nephrology include: a) the typically pediatric field of Congenital Anomalies of the Kidney and Urinary Tract (CAKUT), which has benefited from the discovery of numerous gene mutations responsible for the various malformations and the demonstration of the congenital origin of most of the renal damage, resulting in a decrease of invasive imaging, antibiotic prophylaxis and surgery;

b) the approach to glomerular diseases that appear in childhood, like idiopathic nephrotic syndrome (INS), IgA nephropathy (IgAN) and C3 glomerulopathies (C3G).

B and T lymphocyte disregulations and molecular podocyte alterations of immunological and genetic origin have been described in INS as main determinants of proteinuria. In IgAN, the discovery of an abnormal IgA glycosilation in the mucosal B cells has driven to new trials with Budesonide and Sparsentan and to innovative therapies, like atacicept. A new classification of C3G has been proposed after the description of genetic mutations of factors inhibiting activation of the alternative complement pathway, and monoclonal anti-C5 antibody Eculizumab has consequently entered the therapeutic armamentarium;

c) the initial attempts at gene therapy, with promising results obtained in Alport syndrome, nephropathic cystinosis and Dent syndrome.

Moreover, a clear example of precision medicine is represented by the refinement of the dosage of Eculizumab in the treatment of atypical HUS, while slow-medicine recommendations exist for common clinical conditions, like urinary tract infections, microscopic hematuria and proteinuria.

The aim of the study was to evaluate the effect of self-etching silane primer on long-term bonding strength on feldspathic ceramic. Ceramic blocks (IPS Empress CAD, Ivoclar Vivadent) were cut with a low-speed diamond disk (Isomet 1000, Buehler) into 40 blocks of 12x7x6mm, under water cooling, and randomly divided into two groups (n=20), according to the surface conditioning: hydrofluoric acid (HF) (Condac, FGM) or self-etching silane primer (MEP) (Monobond Etch and Prime, Ivoclar Vivadent). After the blocks were bonded to composite resin blocks (12 x 7 x 3mm) (Liss, FGM) with a light cured cement (Variolink Esthetic LC, Ivoclar Vivadent) and LED photoactivation (Radii Cal, SDI) for 40 s on each luting interface line. The sets were cut in sticks with 1-mm2 cross-section composed of ceramic/cement/composite and tested after 24h (baseline) and 90 days aging by stored in distilled water at 37ºC. Microtensile bond strength testing (mTBS) was performed using a universal machine (DL-1000, EMIC) submitted to traction with speed of 0.5mm/ min until rupture of adhesion. Fracture of specimens were examined under stereomicroscopy to determine the failure pattern. Bond strength (MPa) was calculated, and the failure pattern and interface topography were assessed using scanning electron microscopy (SEM). No significant different mTBS was observed between groups HF and MEP (p>0.05). Storage time of the samples did not affect the mTBS from the groups.  Surface etching pattern with HF produced higher surface alterations than a self-etching primer. Application of MEP may be considered an alternative for silanization for feldspathic ceramic.

The increase in energy consumption in Brazil and in the world generates an increasing need to seek renewable and non-polluting energy, such as biofuels. Safflower (Carthamus tinctorius L.) is a plant with a great oil production capacity and potential for biodiesel production that presents high productivity and easy edaphoclimatic adaptation. It can be an economic culture option in crop rotation practiced by farmers, however it is still necessary to obtain more technical information about its cultivation and about the adapted and improved cultivars. Thus, the estimate of genetic divergence from morphological characters using multivariate techniques has become a common alternative among breeders. In this sense, the objective of this research was to carry out an analysis of the genetic divergence among the 49 safflower genotypes from the germplasm bank of the Instituto Mato Grossense do Algodão (IMA-MT), based on 13 morphological descriptors recommended by the International Board for Plant Genetic Resources - IBPGR (1983) and Ministério da Agricultura, Pecuária e Abastecimento - MAPA (2013).  The divergence analysis was performed by means of the dissimilarity matrix based on multi-categorical variables and to identify the most similar genotypes, Tocher's optimization grouping methods and the hierarchical average grouping method between groups were used. The estimates of the dissimilarity coefficients ranged from 0.00 to 0.46, indicating the presence of genetic diversity among the evaluated genotypes. The highest dissimilarity value was between genotypes 29 and 9, 42 and 1, 42 and 32, 47 and 9, which are the most genetically divergent and thus promising materials for future genetic crosses. The UPGMA dendrogram and tocher grouping were partially consistent and effective in grouping safflower genotypes.

Tooth bleaching has become the first clinical option in reversing chromatic changes. This study evaluated the efficiency of four different approaches for home-based chemically induced tooth whitening. 32 patients were randomly distributed into four groups (n=8), according to the bleaching technique performed: G1: control group – at-home dental bleaching with 10% carbamide peroxide (Whiteness Perfect/FGM) delivered in a customized tray, G2: teeth whitening pen containing hydrogen peroxide (Walgreens), G3: night-time whitening gel (CVS) containing hydrogen peroxide and G4: whitening strips (3D White Oral B) containing 10% hydrogen peroxide. Chromatic changes (ΔE) were collected at baseline and at the middle and end of the treatment, using a digital spectrophotometer (EasyShade – Vita). Tooth sensitivity, gingival irritation, and degree of satisfaction were also recorded. The comparison between the average ΔE means, considering the final and initial values, revealed a statistically significant difference between the results obtained by G1 (ΔE2=11.65) and the other groups (ΔE2 of G2=4.38, G3=4.83 and G4 = 8.32). No significant difference was observed in the occurrence of tooth sensitivity and gingival irritation. The patients from G1 and G4 were more satisfied with the treatment outcome.

As complicações anestésicas parecem relativamente raras, em contraponto trabalhos recentes sugerem que há maior prevalência em gatos do que em cães. As particularidades anestésicas observadas em felinos podem estar diretamente relacionadas às maiores taxas de complicações observadas nestes animais. Aspectos importantes nesta espécie, tais como, ansiedade e estresse perianestésicos são exemplos peculiares, outras causas que podem ser elencadas como coadjuvante na ocorrência de complicações anestésicas é o monitoramento perianestésico, o papel desempenhado por doenças subjacentes assim como o uso correto de equipamentos de anestesia e da anestesia total injetável que por vezes são negligenciados pelos anestesistas. Diante disso, o trabalho objetivou revisar e discutir as principais particularidades anestésicas em felinos, possibilitando ao veterinário compreender os aspectos mais importantes da anestesia destes pacientes, evitando complicações perioperatórias associadas a doenças pré-existentes, agentes anestésicos, controle das vias aéreas, manejo e monitoramento. Esses dados podem ajudar os veterinários a cuidar do paciente sob anestesia e direcionar maior atenção à avaliação e tratamento do paciente antes, durante e após o procedimento.

Published: May 2021

Compreender o que pensam os alunos e professores de cursos superiores de Química sobre a Ciência e sobre o trabalho científico é significativo, tanto no aspecto de diagnóstico quanto para elaborar reflexões sobre a formação de futuros cientistas. Uma discussão pouco explorada na literatura é a importância dos congressos no processo de formação acadêmica na opinião de membros dessa comunidade. Esta pesquisa é do tipo qualitativa, na qual foram analisadas as respostas de um grupo de sujeitos (alunos de pós-graduação e professores) dadas às perguntas: Você costuma ir em congressos científicos? Qual a importância dos congressos científicos na formação científica?. As análises foram feitas utilizando a Análise Textual Discursiva e foi possível concluir que a preferência maior desses sujeitos é a de frequentar congressos específicos da área, dos quais a maioria participa pelo menos uma vez ao ano, principalmente com o objetivo de se atualizar sobre as novidades na pesquisa e interagir com outros pesquisadores.

As condutas desviantes praticada pelos jovens, consideras comportamentos que desafiam as normas e a ordem social, ainda é uma realidade bastante grave observada em diversos países, seja a partir das pesquisas dos especialistas, seja nas estatísticas. O presente texto tem como objetivo aferir a validade empírica da estrutura fatorial da Escala de Condutas Antissociais e Delitivas em distintos países; trata-se de uma medida de avaliação das condutas desviantes que tem sido bastante utilizada com diferentes amostras e que pode ser compreendida como condutas que interferem nos direitos e nos deveres das pessoas, ameaçando o seu bem-estar social e individual. Participaram do estudo, 411 adolescentes, os quais, 137 eram distribuídos em cada país, com idades compreendidas entre os 13 e os 18 anos (M = 15.71 DP = 1,65; Mo = 15). Os resultados indicam que a estrutura fatorial da ECAD foi consistente, bem como, corroborou a organização bi-fatorial desta medida observada nos estudos brasileiros. Foi destaque também, a sua invariância fatorial nas amostras dos distintos países pesquisado, verificando a diferença no CFI entre as amostras. Esta condição revela que a ECAD tem muita qualidade, bem como, permite afirmar que tal fenômeno pouco se diferencia para respondentes em distintos contextos sociais e políticos, quanto ao seu construto. Com isso, pode-se afirmar que ECAD é confiável e segura quando se pretender avaliar as condutas desviantes em jovens.

Diatom aggregates can play an important role in the formation of marine oil snow and the transport of oil from the sea surface to the benthos, yet their molecular response to oil has not been characterized. Here we use RNA-seq to analyze the transcriptome-wide responses of aggregates of the common Gulf of Mexico diatom Odontella aurita exposed to the water accommodated fraction of 2 different types of oil, Macondo surrogate and Refugio Beach oil. We identify a common set of 353 genes that are differentially expressed in response to both Macondo and Refugio oil exposure, relative to controls. Genes related to photosynthesis, and nuclear and ribosomal processes were all down-regulated in oil treatments, while genes related to repairing membrane damage, cellular stress, and the production of exopolymeric substances were up-regulated. Differential expression of genes was often greater in magnitude in the Refugio than the Macondo oil treatment, which may be due to differences in oil concentration in the treatments or to the physiochemical characteristics of the oils. Exposure to Refugio oil induced more severe nucleolar stress and more damage to chloroplasts than the lighter Macondo oil, which triggered an up-regulation of a more diverse suite of stress-response genes.

Sleep is essential component of life. Even though the research in this field develops constantly, there are still many aspects of this rather complex process that remains to be fully clarified. One of these aspects, reason why we actually sleep, is perhaps the most crucial. In this mini review we aim to address this question and discuss potential functions of sleep. Many recent scientific papers are currently available that covers similar topic. We tried to summarize these recent findings. There are certainly many ways how to approach this rather complex issue. Our article will specifically focus on role of sleep in neuronal development, synaptic plasticity, memory consolidation or mental health in general. Its role in immune system functioning will also be mentioned. Moreover, we will also consider more general functions of sleep, such as well-being of the organisms or securing survival of the individual. In conclusion, we will highlight possible main function of sleep.

The association between gene variant rs7635818 located on chromosome 3p12.3 and abdominal aortic aneurysm (AAA) was not unambiguously determined by the results of genome-wide association studies. The aim of our study was to examine this possible association in the Slovak population, with respect to the presence and severity of AAA. A cross-sectional study was conducted between August 2016 and March 2020. The study included 329 participans, 166 AAA patients and a control group of 163 subjects without confirmed AAA with comparable distribution of genders. The anteroposterior diameter of the abdominal aorta was determined by duplex ultrasonography. AAA was defined as subrenal aortic diameter ≥ 30 mm. DNA samples were genotyped using real-time polymerase chain reaction and subsequent high-resolution melting analysis in presence of unlabelled probe. Genetic models studying the possible association were adjusted to age, sex, smoking, arterial hypertension, diabetes mellitus, creatinine and body mass index (BMI) in multivariate analysis. In the additive model, presence of each C-allele of rs7635818 polymorphism was associated with an almost 50 % increase in probability of developing AAA (OR 1.49; 95 % CI 1.06‒2.08; p=0.020). Compared to GG homozygotes, CC homozygotes had more than two times higher risk of developing AAA (OR 2.23; 95 % CI 1.14‒4.39; p=0.020). The risk of AAA was also in the recessive model higher for
CC homozygotes compared to G-allele carriers (GC/GG) (OR 1.79; 95 %CI 1.01‒3.19; p=0.047). The abdominal aortic diameter in CC homozygotes of the rs7635818 polymorphism was 7.66 mm greater compared to GG homozygotes (42.5±22.0 mm vs 34.8±21.3 mm; p=0.022) and 5.88 mm greater compared to G-allele carriers (GC/GG) (42.5±22.0 mm vs 36.6±21.0 mm; p=0.04) in univariate analysis. C-allele variant in rs7635818 G>C polymorphism is associated with a higher probability of developing AAA in the Slovak population.
