ABSTRACT

Abstract The genus Artemisia L. of the family Asteraceae is systematically very complex. The aim of this study was to evaluate taxonomic positions of taxa of the subgenus Artemisia belonging to the genus Artemisia in Turkey using some molecular techniques. In this molecular study, 44 individuals belong to 14 species of the subgenus Artemisia were examined. Analyses were performed on the combined dataset using maximum parsimony, maximum likelihood and Bayesian inference and Molecular parameters obtained from co-evaluations of sequences of the psbA-trnH, ITS and ETS regions of examined individuals were used in the phylogenetic tree drawing. According to the results of this study, two molecular groups have been formed based on the DNA sequence similarity of the species, but there are no obvious morphological characters corresponding to two molecular groups. There is no also agreement between the two molecular groups and the two morphological groups formed according to the hairiness condition of the receptacle of species. Due to the lack of molecular significance of their receptacles with or without hair, dividing of the subgenus Artemisia species into new subgenera or sections was not considered appropriate. Likewise, it has been found that with or without hair on the corolla lobes of the central hermaphrodite disc flowers have no molecular significance. It was found that there were no gene flow and hybridization between the 14 species of the subgenus Artemisia and these 14 species were found completed their speciation. This study is important as it is the first molecular based study relating with belong to subgenus Artemisia species growing naturally in Turkey. In addition, new haplotypes related to the populations of Turkey belonging to the subgenus Artemisia taxa were reported by us for the first time and added to the GenBank database.


Resumo O gênero Artemisia L. da família Asteraceae é sistematicamente muito complexo. O objetivo deste estudo foi avaliar as posições taxonômicas de táxons do subgênero Artemisia pertencentes ao gênero Artemisia na Turquia usando algumas técnicas moleculares. Neste estudo molecular, 44 indivíduos pertencentes a 14 espécies do subgênero Artemisia foram examinados. As análises foram realizadas no conjunto de dados combinado usando máxima parcimônia, máxima verossimilhança e inferência bayesiana e parâmetros moleculares obtidos a partir de coavaliações de sequências das regiões psbA-trnH, ITS e ETS de indivíduos examinados foram usados ​​no desenho da árvore filogenética. De acordo com os resultados deste estudo, dois grupos moleculares foram formados com base na similaridade da sequência de DNA das espécies, mas não há caracteres morfológicos óbvios correspondentes a dois grupos moleculares. Também não há concordância entre os dois grupos moleculares e os dois grupos morfológicos formados de acordo com a condição de pilosidade do receptáculo da espécie. Devido à falta de significado molecular de seus receptáculos com ou sem cabelo, a divisão das espécies do subgênero Artemisia em novos subgêneros ou seções não foi considerada apropriada. Da mesma forma, verificou-se que com ou sem cabelo nos lobos da corola das flores do disco hermafrodita central não tem significado molecular. Constatou-se que não houve fluxo gênico e hibridização entre as 14 espécies do subgênero Artemisia e essas 14 espécies concluíram sua especiação. Este estudo é importante porque é o primeiro estudo de base molecular relacionado com espécies pertencentes ao subgênero Artemisia crescendo naturalmente na Turquia. Além disso, novos haplótipos relacionados às populações da Turquia pertencentes ao subgênero Artemisia taxa foram relatados por nós pela primeira vez e adicionados ao banco de dados do GenBank.

ABSTRACT

Abstract Since water is one of the essentials for life, the presence and quality of water in the habitat is extremely important. Therefore, water quality change and management of Lake Aygır was investigated in this study. For this, water samples collected from the lake and the irrigation pool between May 2015 and May 2016 were analyzed monthly. Spectrophotometric, titrimetric and microbiological methods were used to determine the water quality. According to some water quality regulations, HCO3, NH4, Cu, Mo, Br, fecal coliform and total suspended solid (TSS) values were found above the limit values. The other 29 parameters comply with Turkish national and international legislations. Lake Aygır was negatively affected by the surrounding settlements and agricultural activities. It is thought that the water resource should be monitored periodically and remedial studies should be done to prevent parameters exceeding the limits. However, Lake Aygır was generally suitable for drinking, use, fishing and irrigation.


Resumo Como a água é um dos elementos essenciais para a vida, a presença e a qualidade da água no habitat são extremamente importantes. Portanto, a mudança da qualidade da água e a gestão do lago Aygır foram investigadas neste estudo. Para isso, amostras de água coletadas no lago e na piscina de irrigação entre maio de 2015 e maio de 2016 foram analisadas mensalmente. Métodos espectrofotométricos, titulométricos e microbiológicos foram usados para determinar a qualidade da água. De acordo com alguns regulamentos de qualidade da água, os valores de HCO3, NH4, Cu, Mo, Br, coliformes fecais e total sólido suspenso (TSS) foram encontrados acima dos valores limite. Os outros 29 parâmetros estão em conformidade com as legislações nacionais e internacionais turcas. O lago Aygır foi afetado negativamente pelos assentamentos e atividades agrícolas ao redor. Pensa-se que o recurso hídrico deve ser monitorado periodicamente e estudos corretivos devem ser feitos para evitar que os parâmetros ultrapassem os limites. No entanto, o lago Aygır era geralmente adequado para beber, usar, pescar e irrigar.

ABSTRACT

Abstract The aim of the present study was to determine and compare the fatty acids, lipid soluble vitamins, sterols, phenolics, and antioxidant capacities of three endemic Salvia L. taxa (S. euphratica var. Montbret & Aucher ex Bentham leiocalycina (Rech. Fil.) Hedge, S. euphratica var. Montbret & Aucher ex Bentham euphratica (Rech. Fil.) Hedge and S. pseudoeuphratica Rech.Fil.) and to evaluate these results systematically. The fatty acid compositions were determined by using gas chromatography, while the lipid soluble vitamins, sterols, and phenolics were determined by using HPLC. Also, the antioxidant capacities of three Salvia taxa were measured in vitro. Palmitic acid was found as major saturated fatty acid while oleic acid, linoleic acid, α-linolenic acid, and erucic acid were found as major unsaturated fatty acids in the present study. It was found that S. euphratica var. euphratica had lower palmitic acid (8.94 ± 0.71%), total saturated fatty acid (19.16 ± 0.15%), and higher unsaturated fatty acid content (82.08 ± 0.52%) than other studied taxa. Furthermore, it was shown that S. euphratica var. euphratica had different 18.3/18:2 (0.36) unsaturated/saturated fatty acid (4.28) ratios. However, this study demonstrated that Salvia taxa had low lipid soluble vitamins, sterol contents. On the other hand, it was shown that Salvia taxa had similar catechin (509.2 ± 4.21 µg/g and 552.2 ± 9.21 µg/g) and vanillic acid amounts (351.2 ± 2.17 µg/g and 396.8 ± 4.1 µg/g) in this study. And also, it was found that Salvia taxa had high rosmarinic acid content while S. euphratica var. leiocalycina had the highest rosmarinic acid content (1480 ± 7.57 µg/g). On the other hand, it was shown that the two ferulic acid contents of S. euphratica varieties were higher (1175 ±/5.21 µgmg-1740.2 ± 4.82 µg/mg) than the ferulic acid content of S. pseudoeuphratica of which was the lowest (19.2 ± 0.97 µg/mg). The present results suggested that the biochemical results guided the morphological studies, and Salvia taxa have a potent antioxidant capacity.


Resumo O objetivo do presente estudo foi determinar e comparar os ácidos graxos, vitaminas lipossolúveis, esteróis, fenóis e capacidades antioxidantes de três espécies endêmicas de Salvia L. (S. euphratica var. Montbret & Aucher ex Bentham leiocalycina (Rech. Fil.) Hedge, S. euphratica var. Montbret & Aucher ex Bentham euphratica (Rech. Fil.) Hedge e S. pseudoeuphratica Rech.Fil.) e avaliar esses resultados sistematicamente. As composições de ácidos graxos foram determinadas por cromatografia gasosa, enquanto as vitaminas lipossolúveis, esteróis e fenóis foram determinadas por HPLC. Além disso, as capacidades antioxidantes das três espécies de Salvia foram medidas in vitro. O ácido palmítico foi encontrado como ácido graxo saturado principal, enquanto o ácido oleico, ácido linoleico, ácido α-linolênico e ácido erúcico foram encontrados como principais ácidos graxos insaturados no presente estudo. Verificou-se que S. euphratica var. euphratica tem menor teor de ácido palmítico (8.94 ± 0.71%) e ácido graxo saturado total (19.16 ± 0.15%) e maior teor de ácidos graxos insaturados (82.08 ± 0.52%) do que as outras espécies estudadas. Além disso, foi demonstrado que a S. euphratica var. euphratica apresentou diferentes proporções 18:3/18:2 (0.36) de ácidos graxos insaturados/saturados (4.28). No entanto, este estudo demonstrou que o gênero Salvia tinha baixo teor de vitaminas lipossolúveis e baixo conteúdo de esteróis. Por outro lado, foi demonstrado que as espécies do gênero Salvia contém quantidades de catequinas (509.2 ± 4,21 µg/mg-552.2 ± 9.21 µg/mg) e ácido vanílico semelhantes (351.2 ± 2.17 µg/mg 396,8 ± 4,1 µg/mg). Descobriu-se também que o gênero Salvia tinha alto conteúdo de ácido rosmarínico enquanto a espécie S. euphratica var. leiocalycina apresentou o maior teor desse ácido (1.480 ± 7.57 µg/g). Por outro lado, foi demonstrado que os teores de ácido ferúlico da espécie S. eupratica foram maiores (1.175 ± 5.21 µg/mg-1740.2 ± 4.82 µg/mg) do que o conteúdo de ácido ferúlico da espécie S. pseudoeuphratica dos quais foi o mais baixo (19.2 ± 0.97 µg/mg). Os resultados atuais sugerem que os resultados bioquímicos orientaram os estudos morfológicos e as espécies de Salvia têm uma potente capacidade antioxidante.

ABSTRACT

Abstract Today, most of the world's population faces water scarcity, while global warming, urbanization, industrialization and population increases continue to increase the severity of the pressure on water resources. Management of water resources plays a key role in the sustainability of agricultural production. The water footprint (WF) is different in comparison to other water statistics because it takes direct and indirect water consumption into account, and helps in the management of water resources. Within this context, the WF of Van province, which is Turkey's most easterly located arid region, was calculated from 2004 to 2019. The study area covers lake Van, which is Turkey's largest lake, and the Van basin with an area of 23.334 km2 and a population of 1.136.757 (2019). In the calculations, crop (WFcrop), livestock (WFlivestock), and domestic and industrial water footprints (WFdomestic+industrial) were evaluated separately, and blue and green water footprints (WFblue and WFgreen) were analyzed in detail. According to the results, the average WF of Van province was found to be 8.73 billion m3 year-1. Throughout the province, 87.6% of the WF is composed of WFcrop, 4.9% is WFlivestock and 7.5% is WFdomestic+industrial. Of the WFcrop, 62.5% depends on WFblue, i.e., freshwater. Most of the WFlivestock consisted of dairy cattle (49%) and sheep (38%). The average WFdomestic+industrial for 2004 to 2019 was 0.64 billion m3 year-1. The average per capita water footprint of Van province was found to be 889.9 m3 year-1 capita-1. In addition, the province is classified as severe water scarcity (257%). This study is one of the first province-based calculations of WF in Turkey and is the first study to bring a different aspect to published literature by including residual soil moisture from the winter months. As a result of this study, the WFblue of the WFcrop is above the worldwide average and should be reduced by changing the crop pattern or synchronizing the planting and harvest dates of the crops to a period that benefits from precipitation. In addition, this study is expected to contribute to new studies for calculating the provincial scale WF and will have positive effects on agricultural planning, water allocation and the sustainability of water resources.


Resumo Hoje, a maior parte da população mundial enfrenta a escassez de água, enquanto o aquecimento global, a urbanização, a industrialização e o crescimento da população continuam a aumentar a gravidade da pressão sobre os recursos hídricos. A gestão dos recursos hídricos desempenha papel fundamental na sustentabilidade da produção agrícola. A pegada hídrica (WF) é diferente em comparação com outras estatísticas hídricas porque leva em consideração o consumo direto e indireto de água e auxilia na gestão dos recursos hídricos. Nesse contexto, o WF da província de Van, que é a região árida localizada mais a leste da Turquia, foi calculado de 2004 a 2019. A área de estudo cobre o lago Van, que é o maior lago da Turquia, e a bacia de Van, com uma área de 23,334 km2 e uma população de 1.136.757 (2019). Nos cálculos, as pegadas hídricas de safra (WFcrop), pecuária (WFlivestock) e doméstica e industrial (WFdomestic+industrial) foram avaliadas separadamente, e as pegadas hídricas azul e verde (WFblue e WFgreen) foram analisadas em detalhes. De acordo com os resultados, o WF médio da província de Van foi encontrado em 8,73 bilhões de m3 ano-1. Em toda a província, 87,6% do WF são compostos por WFcrop, 4,9% são WFlivestock e 7,5% são WFdomestic+industrial. Do WFcrop, 62,5% dependem do WFblue, ou seja, de água doce. A maior parte do gado WFlivestock era composto por gado leiteiro (49%) e ovelhas (38%). O WFdomestic+industrial médio de 2004 a 2019 foi de 0,64 bilhão de m3 ano-1. A pegada hídrica per capita média da província de Van foi encontrada em 889,9 m3 ano-1 capita-1. Além disso, a região é classificada como grave escassez de água (257%). Este estudo é um dos primeiros cálculos de WF baseados em províncias na Turquia e é o primeiro estudo a trazer um aspecto diferente para a literatura publicada, incluindo a umidade residual do solo dos meses de inverno. Como resultado deste estudo, o WFblue do WFcrop está acima da média mundial e deve ser reduzido alterando o padrão de cultivo ou sincronizando as datas de plantio e colheita das safras para um período que se beneficie da precipitação. Além disso, espera-se que este estudo contribua para novos estudos para o cálculo da escala provincial WF e terá efeitos positivos no planejamento agrícola, alocação de água e a sustentabilidade dos recursos hídricos.

ABSTRACT

Abstract Artemisia is one of the biggest genera in the family Asteraceae, with around 500-600 taxa at specific and sub-specific levels and organised in 5 subgenera. Due to the high number of taxa, a lot taxonomists are trying to solve the problem of its classification and phylogeny but its natural classification still hasn't been achieved. In this research, 60 individuals belonging to 4 taxa of the subgenus Dracunculus of Artemisia L. in Turkey were examined. For all the examined individuals from both the same and different populations belonging to the taxa of the subgenus Dracunculus, the sequences of the regions both psbA-trnH of chloroplast DNA and ITS of nuclear DNA were determined. Also, the gene regions obtained were recorded in the NCBI GenBank database and an accession number was taken. It was found that there was no gene flow and hybridization between the four studied taxa of the subgenus Dracunculus, and these 4 taxa also completed their speciation. According to the results of this molecular study, A. campestris var. campestris, A. campestris var. marschalliana and A. campestris var. araratica were proposed to be raised from the variety level to the species level. This research is important as it is the first molecular based study relating with the subgenus Dracunculus growing in Turkey.


Resumo Artemisia é um dos maiores gêneros da família Asteraceae, com cerca de 500 a 600 táxons em níveis específicos e subespecíficos e organizados em cinco subgêneros. Em razão do grande número de táxons, muitos taxonomistas estão tentando resolver o problema de sua classificação e filogenia, mas sua classificação natural ainda não foi alcançada. Nesta pesquisa, 60 indivíduos pertencentes a quatro táxons do subgênero Dracunculus de Artemisia L. na Turquia foram examinados. Para todos os indivíduos examinados de populações iguais e diferentes pertencentes aos táxons do subgênero Dracunculus, foram determinadas as sequências das regiões psbA-trnH do DNA do cloroplasto e ITS do DNA nuclear. Além disso, as regiões gênicas obtidas foram registradas no banco de dados do NCBI GenBank e um número de acesso foi obtido. Foi constatado que não houve fluxo gênico nem hibridização entre os quatro táxons estudados do subgênero Dracunculus, os quais também completaram sua especiação. De acordo com os resultados deste estudo molecular, A. campestris var. campestris, A. campestris var. marschalliana e A. campestris var. araratica foram propostos para ser elevados do nível de variedade para o nível de espécie. Esta pesquisa é importante porque é o primeiro estudo de base molecular relacionado com o subgênero Dracunculus em crescimento na Turquia.

ABSTRACT

The research was conducted to determine forage yield and some quality characteristics of Hungarian vetch + triticale mixture, sowed in five different times under rainfed conditions of Central Anatolia, Turkey. The mixture was sowed in the second, third and fourth week of October, and the first and the second week of November in 2017 and 2018. Depending on the sowing times, plant height (PH) of Hungarian vetch and triticale was between 46.7 and 59.4 cm, and 85.9 and 93.4 cm, respectively. Green forage yield (GFY) was between 1746.2 and 2059.4 kg da-1, dry matter yield (DMY) was between 541.0 and 707.6 kg da-1, crude protein yield (CPY) was between 80.4 and 110.3 kg da-1, digestible dry matter yield (DDMY) was between 340.8 and 453.9 kg da-1, acid detergent fiber (ADF) ratio was between 31.8 and 33.7%, neutral detergent fiber (NDF) ratio was between 44.7 and 49.5%, total digestible nutrient (TDN) was between 57.9 and 60.4% and relative feed value (RFV) was between 118.6 and 133.8. Sowing time had a significant effect (P < 0.05) on PH of triticale, while it has a very significant effect (P < 0.01) on GFY, DMY, CPY, DDMY, NDF ratios and RFV. Delaying the sowing time caused a decrease in the GFY, DMY and quality of the mixture. Results revealed that the first week of October is the most appropriate sowing time to obtain high dry matter yield with high quality under continental climate conditions of the Central Anatolia.


A pesquisa foi conduzida para determinar a produção de forragem e algumas características de qualidade da mistura de ervilhaca húngara + triticale, semeada em cinco épocas diferentes em regime de sequeiro na região Central da Anatólia, Turquia. A mistura foi semeada na segunda, terceira e quarta semanas de outubro, e na primeira e segunda semanas de novembro de 2017 e 2018. Dependendo da época de semeadura, a altura da planta (PH) da ervilhaca e triticale húngara foi entre 46,7 e 59,4 cm e 85,9 e 93,4 cm, respectivamente. O rendimento de forragem verde (GFY) ficou entre 1746,2 e 2059,4 kg da-1, o rendimento de matéria seca (DMY) foi entre 541,0 e 707,6 kg da-1, o rendimento de proteína bruta (CPY) foi entre 80,4 e 110,3 kg da-1, digestível seco o rendimento de matéria (DDMY) estava entre 340,8 e 453,9 kg da-1, a proporção da fibra em detergente ácido (FDA) estava entre 31,8 e 33,7%, a proporção da fibra em detergente neutro (FDN) estava entre 44,7 e 49,5%, o nutriente digestível total (NDT) era entre 57,9 e 60,4% e o valor relativo da alimentação (RFV) foi entre 118,6 e 133,8. A época de semeadura teve um efeito significativo (P < 0,05) no PH do triticale, enquanto teve um efeito muito significativo (P < 0,01) nas relações GFY, DMY, CPY, DDMY, FDN e RFV. O atraso na semeadura ocasionou diminuição no GFY, DMY e na qualidade da mistura. Os resultados revelaram que a primeira semana de outubro é a época de semeadura mais adequada para a obtenção de alta produtividade de matéria seca com alta qualidade nas condições climáticas continentais da Anatólia Central.

ABSTRACT

Abstract Medicinal plants have a significant role in preventing and curing several diseases, and Tanacetum L. is one of these plants. The aim of the present study is to determine the fatty acid, lipid-soluble vitamin, sterol, phenolic content, and antioxidant capacity of Tanacetum densum subsp. laxum and Tanacetum densum subsp. amani, to compare the effect of altitude on the biochemical content and to compare systematically by using fatty acids and phenolics. This study showed that palmitic acid (C16:0) and stearic acid (C18:0) are major sources of saturated fatty acid and oleic acid (C18:1 n9), and linoleic acid (18:2 n6c) and a-linolenic acid (C18:3 n3) are the principal unsaturated fatty acids in the two endemic Tanacetum densum taxa. Also, this study found that the unsaturated fatty acid content (60.11±1.61%) of Tanacetum densum subsp. laxum was higher than the unsaturated fatty acid content (44.13±1.28%) of Tanacetum densum subsp. amani. And also, the ω6/ω3 ratio of Tanacetum densum subsp. laxum (1.74) and Tanacetum densum subsp. amani (1.60) was found to be similar. However, this study determined that the lipid soluble vitamin and sterol content of two endemic Tanacetum taxa are low except for stigmasterol. Present study showed that catechin is principal phenolic in the Tanacetum densum taxa. This study also found that Tanacetum densum subsp. laxum and Tanacetum densum subsp. amani had the highest levels of catechin, vanillic acid, and caffeic acid content though the phenolic amounts, particularly catechin and quercetin, were dissimilar in the T. densum taxa. This study suggested that ecological conditions such as altitude may affect the biochemical content of two endemic Tanacetum densum taxa. Furthermore, the current study determined that two endemic Tanacetum L. taxa had potent radical scavenging capacities and found a correlation between total phenolics and antioxidant activity.


Resumo As plantas medicinais têm um papel significativo na prevenção e cura de várias doenças, e Tanacetum L. é uma dessas plantas. O objetivo do presente estudo é determinar o conteúdo de ácido graxo, vitamina lipossolúvel, esterol, estrutura fenólica e capacidade antioxidante de Tanacetum densum subsp. laxum e Tanacetum densum subsp. amani, comparar o efeito da altitude sobre o conteúdo bioquímico e realizar uma comparação sistemática usando ácidos graxos e fenólicos. Esta pesquisa mostrou que o ácido palmítico (C16:0) e o ácido esteárico (C18:0) são as principais fontes de ácido graxo saturado e que o ácido oleico (C18:1 n9), o ácido linoleico (18:2 n6c) e o ácido a-linolênico (C18: 3 n3) são os principais ácidos graxos insaturados nos dois táxons endêmicos de Tanacetum densum. Além disso, este estudo descobriu que o conteúdo de ácidos graxos insaturados (60,11±1,61%) de Tanacetum densum subsp. laxum foi superior ao conteúdo de ácidos graxos insaturados (44,13±1,28%) de Tanacetum densum subsp. amani, e também que a razão ω6/ω3 de Tanacetum densum subsp. laxum (1,74) e Tanacetum densum subsp. amani (1,60) foi semelhante. No entanto, este trabalho determinou que o conteúdo de vitamina lipossolúvel e esterol de dois táxons endêmicos de Tanacetum é baixo, exceto o estigmasterol, além de descobrir que Tanacetum densum subsp. laxum e Tanacetum densum subsp. amani apresentaram os mais altos níveis de conteúdo de catequina, ácido vanílico e ácido cafeico, embora as quantidades fenólicas, especialmente catequina e quercetina, sejam diferentes nos táxons de T. densum. Este estudo sugere que condições ecológicas, como a altitude, podem afetar o conteúdo bioquímico de dois táxons endêmicos de Tanacetum densum. Ainda, esta pesquisa determinou que dois táxons de Tanacetum L. endêmicos possuíam potentes capacidades de sequestro de radicais e que houve correlação entre fenólicos totais e atividade antioxidante.

ABSTRACT

In this study, milk yield, reproductive yield, and type traits of 533 Holstein cows in the first lactation raised in 54 farms were examined. In the three-year study, phenotypic (rP) and genetic (rG) correlations between type traits and milk yield were estimated based on the variance elements and heritability of the type traits of Holstein cows in the first lactation. Linear identification and scoring systems have been applied to classify the cows according to type traits. Heritability and correlations were estimated with ASREML models. The type traits included stature, angularity, rump width, hocks, rear udder height, central ligament, teat length, body capacity, feet and legs, udder composite and final score for genetic correlations with 305-day milk yield were estimated as -0.49, -0.14, -0.93, 0.35, 0.40, 0.11, -0.65, 0.70, 0.31, 0.54, and 0.70, for phenotypic correlations were estimated as 0.28, 0.28, 0.30, 0.21, 0.35, 0.39, -0.06, 0.46, 0.48, 0.56, and 0.58 respectively. Among the phenotypic correlations between the type traits, especially the phenotypic correlations between the final score and various type traits were found to be high and significant. The fact that these traits are in high correlation with other traits and milk yield may enable these to be used as indirect selection criteria in the selection for milk yield.(AU)


Neste estudo, foram examinadas a produção de leite, a produção reprodutiva e as características de tipo de 533 vacas Holstein na primeira lactação criadas em 54 fazendas. No estudo trienal, as correlações fenotípicas (rP) e genéticas (rG) entre características de tipo e produção de leite foram estimadas com base nos elementos de variação e hereditariedade das características de tipo das vacas Holstein na primeira lactação. Sistemas de identificação linear e de pontuação foram aplicados para classificar as vacas de acordo com os traços de tipo. A hereditariedade e correlações foram estimadas com os modelos ASREML. Os traços de tipo incluíam estatura, angularidade, largura da alcatra, jarretes, altura do úbere traseiro, ligamento central, comprimento das tetas, capacidade corporal, pés e patas, composição do úbere e pontuação final para correlações genéticas com a produção de leite de 305 dias foram estimados como -0. 49, -0,14, -0,93, 0,35, 0,40, 0,11, -0,65, 0,70, 0,31, 0,54, e 0,70, para correlações fenotípicas foram estimadas como 0,28, 0,28, 0,30, 0,21, 0,35, 0,39, -0,06, 0,46, 0,48, 0,56, e 0,58 respectivamente. Dentre as correlações fenotípicas entre os traços de tipo, especialmente as correlações fenotípicas entre a pontuação final e vários traços de tipo foram encontradas como altas e significativas. O fato destes traços estarem em alta correlação com outros traços e a produção de leite pode permitir que sejam usados como critérios de seleção indiretos na seleção para a produção de leite.(AU)

Abstract Objective To investigate depression and sexual function among pregnant and nonpregnant women throughout the COVID-19 pandemic. Methods A total of 188 women, 96 pregnant and 92 non-pregnant were included. The Beck Depression Inventory (BDI) and the Arizona Sexual Experience Scale (ASEX) were applied to the participants after obtaining sociodemographic data. Results The depression scores of pregnant and non-pregnant women were similar (p = 0.846). We found that the depression scores were significantly higher among the group of participants who have lower economic status (p = 0.046). Moreover, the depression score was significantly higher among women who lost their income during the pandemic (p = 0.027). The score on the ASEX was significantly higher, and sexual dysfunction was more prevalent among women who have lower levels of schooling and income (p < 0.05). Likewise, the ASEX scores were significantly higher (p = 0.019) among the group who experienced greater income loss throughout the pandemic. Upon comparing the pregnant and non-pregnant groups, we detected that sexual dysfunction had a significantly higher rate among pregnant women (p < 0.001). Conclusion In times of global crisis, such as the current pandemic, low-income families have an increased risk of experiencing depression and sexual dysfunction. When we compared pregnant women with non-pregnant women, depression scores were similar, but pregnant women were at a 6.2 times higher risk of developing sexual dysfunction.


Resumo Objetivo Investigar a depressão e as funções sexuais de mulheres grávidas e não grávidas durante a pandemia de Covid-19. Métodos Um total de 188 mulheres, 96 grávidas e 92 não grávidas, foram incluídas. O Inventário de Depressão de Beck (Beck Depression Inventory, BDI, em inglês) e a Escala de Experiências Sexuais do Arizona (Arizona Sexual Experience Scale, ASEX, em inglês) foram aplicados aos participantes após a obtenção dos dados sociodemográficos. Resultados As pontuações de depressão de mulheres grávidas e não grávidas foram semelhantes (p = 0,846). Verificou-se que as pontuações de depressão foram significativamente maiores no grupo de participantes de menor nível econômico (p = 0,046). Além disso, a pontuação de depressão foi significativamente maior em mulheres que perderam sua renda durante a pandemia (p = 0,027). A pontuação na ASEX foi significativamente maior, e a disfunção sexual foi mais prevalente em pessoas com menores escolaridade e nível de renda (p < 0,05). Da mesma forma, as pontuações na ASEX foram significativamente mais altas (p = 0,019) no grupo que experimentou maior perda de renda durante a pandemia. Ao comparar os grupos de gestantes e não gestantes, detectou-se que a disfunção sexual apresentava índice significativamente Conclusão Em tempos de crise global, como a atual pandemia, famílias de baixa renda têm um risco maior de sofrer depressão e disfunção sexual. Quando comparamos mulheres grávidas e mulheres não grávidas, as pontuações de depressão foram semelhantes, mas as mulheres grávidas apresentaram um risco 6,2 vezes maior de desenvolver disfunção sexual.

ABSTRACT

The purpose of this study was to model the factors affecting the 305-day milk yield of dairy cows by using Automatic Linear Modeling Technique (ALM). The data set of this study consisted of eight different cow breeds grown in eight province of Turkey. Results of ALM showed that the accuracy of the model was 64.2 % means that 64.2% of the variation in the 305-day milk yield could be explained by the constructed model. Created model was consisted of four factors namely the Breed, Lactation Length, Parity, and Province. Therefore, those selected factors were more efficient than the others in predicting the 305-day milk yield.(AU)


O objetivo deste estudo foi modelar os fatores que afetam a produção de leite das vacas leiteiras em 305 dias, utilizando a Técnica de Modelagem Linear Automática (ALM). O conjunto de dados deste estudo consistia em oito raças diferentes de vacas cultivadas em oito províncias da Turquia. Os resultados da ALM mostraram que a precisão do modelo era de 64,2% significa que 64,2% da variação na produção de leite de 305 dias poderia ser explicada pelo modelo construído. O modelo criado consistia de quatro fatores: Raça, Comprimento da Lactação, Paridade e Província. Portanto, esses fatores selecionados foram mais eficientes do que os outros na previsão da produção de leite de 305 dias.(AU)

ABSTRACT

ABSTRACT BACKGROUND: In July 2012, the Japan Gastroenterological Endoscopy Society updated their guidelines for gastroenterological endoscopy in patients receiving antithrombotic therapy. Colonoscopic polypectomy procedures are associated with a high risk of bleeding. OBJECTIVES: The present study evaluated the safety of colonoscopic polypectomy procedures in terms of bleeding, among patients receiving antithrombotic therapy. DESIGN AND SETTING: Prospective observational study conducted in a tertiary-level public cardiovascular hospital in Istanbul, Turkey. METHODS: Colonoscopic polypectomies carried out in a single endoscopy unit between July 2018 and July 2019 were evaluated prospectively. The patients' data, including age, gender, comorbidities, whether antithrombotic drug use was ceased or whether patients were switched to bridging therapy, polyp size, polyp type, polyp location, histopathology, resection methods (hot snare, cold snare or forceps) and complications relating to the procedures were recorded. RESULTS: The study was completed with 94 patients who underwent a total of 167 polypectomy procedures. As per the advice of the physicians who prescribed antithrombotic medications, 108 polypectomy procedures were performed on 60 patients without discontinuing medication and 59 polypectomy procedures were performed on 34 patients after discontinuing medication. The age, gender distribution and rate of bleeding did not differ significantly between the patients whose medication was discontinued and those whose medication was continued (P > 0.05). CONCLUSION: This study found that the colonoscopic polypectomy procedure without discontinuation of antithrombotic medication did not increase the risk of bleeding. This procedure can be safely performed by experienced endoscopists in patients with an international normalized ratio (INR) below 2.5.

ABSTRACT

ABSTRACT BACKGROUND: Vitamin D has relationships with pathogenesis and inflammation pathways in many diseases. Its deficiency may make clinicians think not only of supplementation but also of presence of other diseases. OBJECTIVE: To investigate the relationship between vitamin D levels and deep vein thrombosis (DVT), given that reduced levels are related to increased risk of cardiovascular diseases. DESIGN AND SETTING: Case-control study conducted in the cardiovascular surgery and family medicine departments of a hospital in Turkey. METHODS: A total of 280 participants were included: 140 each in the DVT and control groups. Basic clinical characteristics, comorbidities and serum 25-hydroxyvitamin D (25(OH)D) levels were recorded and then compared between the groups. Serum 25(OH)D levels were also evaluated separately in three subgroups (sufficient, insufficient and deficient). RESULTS: Serum 25(OH)D levels were significantly lower in the DVT group than in the controls (P < 0.001). Females in the DVT group had lower 25(OH)D levels than those in the control group (P = 0.002). Nonetheless, the median 25(OH)D level (16.41 ng/ml) of the control group was still below the reference value. Logistic regression analysis showed that 25(OH)D was a significant predictor of DVT. Weight, height and body mass index, which all presented interaction, were significant in the logistic regression analysis but not in individual analyses. CONCLUSION: The serum vitamin D levels of DVT patients were lower than those of controls. If the results obtained from our study are supported by further large-scale randomized controlled trials, vitamin D replacement may be brought into the agenda for protection against DVT.

ABSTRACT

ABSTRACT BACKGROUND: Coronavirus disease 2019 (COVID-19) causes negative life changes brought about through lockdowns, in addition to severe complications and death. Among these changes, asplenism or hyposplenism has been reported in patients with celiac disease. It has been reported that the risk of pneumococcal sepsis is higher in celiac patients with hyposplenism. Moreover, celiac patients present high risk of admission to hospital due to influenza. OBJECTIVE: To determine the degree of awareness of COVID-19 among parents of children with celiac disease and examine the measures that they take. DESIGN AND SETTING: Cross-sectional study at a university hospital in the Middle Anatolian region of Turkey. METHODS: The diagnosis of celiac disease was confirmed through a survey conducted online among 73 parents between May and July 2020. RESULTS: The mean age was 37.57 ± 6.56 years for the mothers, 41.15 ± 5.56 years for the fathers and 11.36 ± 4.36 years for the children. 90.4% of the parents reported that COVID-19 was transmitted through "speaking, coughing, sneezing and infection of the face after contact with virus-infected surfaces". Moreover, 78.1% indicated that they did not have any difficulty in finding gluten-free foods. CONCLUSION: These parents of children with celiac disease believed that their children's risk of developing COVID-19 did not differ from that of healthy children. It was also observed that appetite and states of nervousness were higher among these children with celiac disease during lockdowns and that their sleep patterns were affected.

ABSTRACT

ABSTRACT BACKGROUND: Healthcare institutions are confronted with large numbers of patient admissions during large-scale or long-term public health emergencies like pandemics. Appropriate and effective triage is needed for effective resource use. OBJECTIVES: To evaluate the effectiveness of the Pandemic Medical Early Warning Score (PMEWS), Simple Triage Scoring System (STSS) and Confusion, Uremia, Respiratory rate, Blood pressure and age ≥ 65 years (CURB-65) score in an emergency department (ED) triage setting. DESIGN AND SETTING: Retrospective study in the ED of a tertiary-care university hospital in Düzce, Turkey. METHODS: PMEWS, STSS and CURB-65 scores of patients diagnosed with COVID-19 pneumonia were calculated. Thirty-day mortality, intensive care unit (ICU) admission, mechanical ventilation (MV) need and outcomes were recorded. The predictive accuracy of the scores was assessed using receiver operating characteristic curve analysis. RESULTS: One hundred patients with COVID-19 pneumonia were included. The 30-day mortality was 6%. PMEWS, STSS and CURB-65 showed high performance for predicting 30-day mortality (area under the curve: 0.968, 0.962 and 0.942, respectively). Age > 65 years, respiratory rate > 20/minute, oxygen saturation (SpO2) < 90% and ED length of stay > 4 hours showed associations with 30-day mortality (P < 0.05). CONCLUSIONS: CURB-65, STSS and PMEWS scores are useful for predicting mortality, ICU admission and MV need among patients diagnosed with COVID-19 pneumonia. Advanced age, increased respiratory rate, low SpO2 and prolonged ED length of stay may increase mortality. Further studies are needed for developing the triage scoring systems, to ensure effective long-term use of healthcare service capacity during pandemics.

ABSTRACT

Introducción. Los pediatras, cirujanos y subespecialistas, como urólogos y nefrólogos pediátricos, participan en el diagnóstico y tratamiento de la nefrolitiasis pediátrica. El objetivo fue determinar los enfoques de distintas disciplinas y evaluar las diferencias en sus protocolos de diagnóstico y tratamiento habituales.Población y métodos. Cuestionario administrado a participantes de sesiones sobre nefrolitiasis en congresos nacionales en 2017 para evaluar las rutinas de diagnóstico y tratamiento de la nefrolitiasis entre distintas especialidades (cirujanos y pediatras) y subespecialidades (nefrólogos pediátricos y urólogos pediátricos).Resultados. Se analizaron 324 cuestionarios de 88 pediatras, 121 urólogos, 23 cirujanos pediátricos, 54 nefrólogos pediátricos y 38 urólogos pediátricos. Ambos grupos coincidieron en la necesidad de una evaluación metabólica. Para los cálculos ureterales distales ≥6 mm, los cirujanos preferían una ureteroscopía; los pediatras, una litotricia por ondas de choque (LOC) (p < 0,001); y los subespecialistas, una ureteroscopía (p = 0,636). Para los cálculos en la parte inferior de los cálices renales < 1 cm, los cirujanos y los subespecialistas preferían la LOC y los pediatras, la hidratación (p < 0,001; p = 0,371). Para los cálculos de entre 1,1 cm y 2 cm, los cirujanos preferían la cirugía retrógrada intrarrenal (CRIR) y la LOC, y los pediatras, la LOC (p = 0,001). Para los cálculos más grandes, los cirujanos y subespecialistas preferían la nefrolitotomía percutánea (NLP) y los pediatras, la LOC (p = 0,458; p = 0,001).Conclusión. Existen diferencias entre las disciplinas que participan activamente en el diagnóstico y tratamiento de la nefrolitiasis


Introduction. Pediatricians, surgeons and subspecialties as pediatric urology and nephrology are involved in the diagnosis and treatment of pediatric renal stone disease (RSD). The aim of this study was to determine diagnostic and treatment approaches, of different disciplines, and to assess differences in their routine diagnostic and treatment protocols.Population and methods. A questionnaire was designed and administered to the participants of the RSD sessions in national congresses of all disciplines in 2017 to evaluate the diagnostic and treatment routines of specialties (surgeons and pediatricians) and subspecialties (pediatric nephrologists and pediatric urologists) for RSD. Results. A total, of 324 questionnaires were analyzed, from 88 pediatricians (27 %), 121 urologists (37 %), 23 pediatric surgeons (7 %), 54 pediatric nephrologists (17 %), and 38 pediatric urologists (12 %). Both groups agreed on the necessity of metabolic evaluation. For distal ureter stones that were ≥ 6 mm; surgeons preferred ureteroscopy (URS), pediatricians preferred shock wave lithotripsy (SWL) (p < 0.001) and subspecialties preferred URS for the treatment (p = 0.636). For lower calix stones less than 1 cm surgeons and subspecialists preferred SWL, while pediatricians preferred hydration (p < 0.001, p = 0.371). For the stone between 1.1 and 2 cm, surgeons preferred intrarenal surgery (RIRS) and SWL, pediatricians preferred SWL (p = 0.001). For larger stones, surgeons and subspecialists preferred percutaneous nephrolithotomy (PCNL), and pediatricians preferred SWL (p = 0.458 p = 0.001). Pediatric urologist chose low-dose computerized tomography as a diagnostic radiologic evaluation (p = 0.029).Conclusion. There are differences between the disciplines who take an active role in diagnosis and treatment of RSD.

ABSTRACT

Introducción. En estudios anteriores, el uso excesivo o la exposición temprana a pantallas se asoció con atención deficiente, falta de control de la conducta, retraso del lenguaje y déficit en la función ejecutiva. El objetivo de este estudio fue investigar la relación entre el tiempo de uso de pantallas y la regulación emocional, que afecta las relaciones sociales de los niños de 2 a 5 años.Población y métodos. Estudio descriptivo transversal en un hospital universitario del 1.º de enero al 1.º de marzo de 2018. Se incluyó a madres de niños sanos de 2 a 5 años con un uso de pantallas inferior a 1 hora o superior a 4 horas. A quienes aceptaron participar se les administró una encuesta estructurada y la Emotion Regulation Checklist para padres.Resultados. De los 240 niños participantes, 98 (el 40,8 %) tenían un uso de pantallas ≥ 4 horas. Ser cuidado por la madre, tener 12 meses o más durante la primera exposición y no estar acompañado por los padres al usarlas se asociaron con ≥ 4 horas de uso de pantallas (p = 0,002; p = 0,002; p = 0,012, respectivamente). La proporción de participantes con una puntuación alta de labilidad/negatividad (L/N) fue significativamente mayor entre los niños con ≥ 4 horas de uso de pantallas y que no estaban acompañados por sus padres al usarlas (p = 0,004; p = 0,033, respectivamente).Conclusiones. Este estudio determinó que un uso excesivo de pantallas se asocia con labilidad emocional durante esta etapa temprana de la infancia.


Introduction. Previous studies have found that excessive screen time or early screen exposure is associated with poor attention, lack of behavioral control, delayed language and deficit in executive functions. The aim of this study was to investigate the relationship between screen time and emotion regulation skills, which is one of the important life components affecting the social relations of children aged 2 to 5 years.Population and methods.This cross-sectional descriptive study was carried out in a university hospital between January 1, 2018 and March 1, 2018. Mothers of healthy children aged 2-5 years with a daily screen time of less than 1 hour or over 4 hours were included in the study. A structured survey and the Emotion Regulation Checklist for parents were applied to the mothers who agreed to participate.Results. Of 240 children participating in the study, 98 (40.8 %) had ≥4 hours of screen time. Caring by mother, age at first screen exposure 12 months and older, not co-viewing with parents were found to be associated with ≥ 4 hours of screen time (p = 0.002, p = 0.002, p = 0.012, respectively). The ratio of participants with high-lability/negativity (L/N) score was significantly higher in children with screen time of ≥ 4 hours and not co-viewing with parents (p = 0.004, p = 0.033, respectively).Conclusions. This study investigating the relationship between the emotion regulation skill and screen time revealed that excessive screen time is associated with emotional lability in this early childhood period.

ABSTRACT

Introducción. La obesidad infantil puede causar hiperlipidemia y esteatosis hepática y complicaciones crónicas. Nuestro objetivo fue evaluar la relación entre el espesor de la grasa subcutánea abdominal (GSA) y la esteatosis hepática, las transaminasas y los lípidos séricos en niños obesos.Población y métodos. Estudio retrospectivo en niños (4-18 años) que acudieron a los consultorios externos. Se evaluaron las asociaciones entre el espesor de la GSA mediante ecografía y la esteatosis hepática, alanina aminotransferasa (ALT), aspartato aminotransferasa (AST) y el perfil lipídico sérico.Resultados. Se identificaron 95 niños con esteatosis hepática; el grado 1 fue el más frecuente (73,6 %, n: 70), seguido del grado 2 (21,1 %) y del 3 (5,3 %). El espesor medio (en mm) de la GSA de línea media y flancos fue 38,48 ± 11,53 y 20,91 ± 8,00 en grado 1; 41,23 ± 10,03 y 19,84 ± 6,75 en grado 2, y 63,12 ± 12,08 y 23,22 ± 5,92 en grado 3, respectivamente. El espesor de la GSA de línea media y flancos se correlacionó positivamente con triglicéridos en grado 3; el espesor de la GSA de línea media se correlacionó con el índice de masa corporal, colesterol total, colesterol LDL y AST (r: 0,9; p: 0,037; r: 0,648; p: 0,001; r: 0,387; p: 0,001; r: 0,406; p: 0,001; r: 0,463; p: 0,001; respectivamente) en grado 1.Conclusión. El espesor de la GSA mediante ecografía puede predecir hiperlipidemia en niños obesos con esteatosis hepática de grado 3 e hipercolesterolemia en grado 1.


Introduction. Childhood obesity can cause hyperlipidemia and hepatic steatosis at early age and chronic disease complications in adult life. We aimed to evaluate the relationship between abdominal subcutaneous fat thickness (ASFT) and hepatic steatosis, serum lipid and transaminase levels in obese children.Population and methods. A retrospective study was conducted with children (aged 4-18 years) who presented to outpatient clinic due to obesity. Associations between ASFT as assessed by ultrasonography (US) and hepatic steatosis, alanine transaminase (ALT), aspartate transaminase (AST) and serum lipid profile were evaluated.Results. We identified 95 children, all of which were diagnosed as having hepatic steatosis; the most common type was grade 1 (73.6 %, n: 70), followed by grade 2 (21.1 %) and grade 3 (5.3 %). The mean values of midline and flank ASFT were measured as 38.48 ± 11.53 mm and 20.91 ± 8.00 mm in grade 1; 41.23 ± 10.03 and 19.84 ± 6.75 in grade 2 and 63.12 ± 12.08 and 23.22 ± 5.92 in grade 3 hepatic steatosis, respectively. Midline and flank ASFT correlated positively with triglycerides in grade 3 steatosis, while midline ASFT correlated with body mass index, total cholesterol, low-density lipoprotein cholesterol, and AST (r: 0.9; p: 0.037; r: 0.648, p: 0.001; r: 0.387, p: 0.001; r: 0.406, p: 0.001, r: 0.463, p: 0.001; respectively) in grade 1 steatosis.Conclusion. ASFT as assessed by US may be of predictive value for hyperlipidemia in grade 3 and for hypercholesterolemia in grade 1 hepatic steatosis in obese children.

ABSTRACT

La gripe se asocia al aparato respiratorio, especialmente en invierno, y puede causar complicaciones neurológicas. Se evaluó a pacientes pediátricos con manifestaciones neurológicas graves por gripe desde septiembre de 2018 hasta febrero de 2019 para determinar características clínicas, neuroimagenología, tratamiento y resultados. El objetivo fue evaluar la encefalitis asociada a la gripe y destacar diferentes manifestaciones neurológicas y cambios de neuroimagenología. El estudio incluyó a 13 pacientes. Los síntomas neurológicos ocurrieron tras los síntomas típicos de la gripe. Los cambios de neuroimagenología incluyen alteraciones de señal de la sustancia blanca cortical y subcortical, edema localizado o generalizado y lesiones multifocales simétricas bilaterales en el tálamo y la médula del cerebelo. Las opciones terapéuticas incluyen metilprednisolona en inyección intravenosa, inmunoglobulina intravenosa, plasmaféresis y oseltamivir. Es fundamental considerar la encefalitis asociada a la gripe en pacientes con convulsiones, la encefalopatía con hallazgos radiológicos compatibles, e iniciar el tratamiento lo antes posible


Influenza is mostly associated with the respiratory tract system, especially in the winter season. Various neurological complications could occur due to influenza infection. Pediatric patients who had severe neurological manifestations due to influenza infection from September 2018 to February 2019 were evaluated for clinical characteristics, neuroimaging studies, treatment, and outcome. We aimed to assess Influenza-associated encephalitis in children, emphasize different neurological manifestations and neuroimaging changes. Thirteen patients were included in the study. Neurological symptoms occurred after flu-like symptoms. Neuroimaging changes of influenza-associated encephalitis/encephalopathy include cortical and subcortical white matter signal alterations, localized or generalized edema, and bilateral symmetrical multifocal lesions on the thalamus and cerebellar medulla. Pulse methylprednisolone, intravenous immunoglobulin, plasma exchange, and oseltamivir are the therapy choices. It is essential to consider influenza-associated encephalitis in patients with seizures, encephalopathy with supporting radiological findings, especially during the influenza season and starting treatment as fast as possible for better outcomes.

ABSTRACT

In this study, fish's morphologic and anatomic lesions caused by motile aeromonad septicemia (MAS) depending on environmental stress in carp, Cyprinus carpio population living in Lake Tödürge were identified. Various morphological and anatomical deformations and lesions were observed in the body of approximately 17% (252 fish specimens) of a total of 1488 carp samples. Bacteria are grown from all wipe samples. Bacterial colonies have a gray-white appearance with round, convex and smooth edges. 15-20 cfu colonies were observed in each aerop culture. As a result of analysis of wet wipe samples from infected fish's skin, gill, kidney and liver, it is determined that the bacteria which causes septicemia is Aeromonas sobria from the Aeromonadaceae family (with 99.2% confidence value). No bacteria were grown in cultures except A. sobria. Some symptoms of the infection are inflammation on different parts of the fish bodies, eruption on skin and scales, dermal necrosis, degeneration at soft rays of the fins, exophthalmos, and purulent liquid accumulation in the abdominal cavity, etc. Infected fish were most commonly encountered in July and August (water temperature above 20ºC), the lowest in October and November (water temperature below 10ºC).(AU)


Neste estudo, foram identificadas lesões morfológicas e anatômicas causadas por septicemia móvel por aeromônios (MPA), dependendo do estresse ambiental da carpa, a população de Cyprinus carpio que vive no lago Tödürge foi identificada. Várias deformações e lesões morfológicas e anatômicas foram observadas no corpo de aproximadamente 17% (252 amostras de peixes) de um total de 1488 amostras de carpa. As bactérias são cultivadas a partir de todas as amostras de limpeza. As colônias bacterianas têm uma aparência branco-acinzentada, com bordas arredondadas, convexas e lisas. Foram observadas 15-20 colônias de UFC em cada cultura de aerop. Como resultado da análise de amostras de lenços umedecidos da pele, brânquias, rins e fígado de peixes infectados, é determinado que a bactéria que causa a septicemia é a Aeromonas sobria, da família Aeromonadaceae (com valor de confiança de 99,2%). Nenhuma bactéria foi cultivada em culturas, exceto A. sobria. Alguns sintomas da infecção são inflamação em diferentes partes dos corpos dos peixes, erupção na pele e escamas, necrose dérmica, degeneração aos raios moles das barbatanas, exoftalmia e acúmulo de líquido purulento na cavidade abdominal, entre outros. Os peixes infectados eram encontrados com maior frequência em julho e agosto (temperatura da água acima de 20ºC), e eram menos comumente encontrados em outubro e novembro (temperatura da água abaixo de 10ºC).(AU)

ABSTRACT

INTRODUCTION: The Coronavirus disease 2019 (COVID-19) pandemic and its consequences have created anxiety in various segments of society. In particular, the transition to online education brought by this process has made the education process of university students difficult. Therefore, in the COVID-19 pandemic, it is important to examine the anxiety levels of university students and their relationship with somatic symptoms. OBJECTIVE: To examine the level of generalised anxiety disorder and to reveal the relationship between somatic symptoms and the generalised anxiety disorder level of Turkish university students. METHODS: Empirical research. Participants in the research constituted a total of 605 students studying at a private university in Istanbul. The Generalised Anxiety Disorder Scale (GAD-7) was used to collect data. Data were analysed using the chi-square test and Pearson correlation analysis. RESULTS: It was found that, among the participants, 193 (31.90%) of the students had mild anxiety, 149 (24.63%) had moderate anxiety and 121 (20.00%) had severe anxiety. The study revealed that there is a significant positive relationship between the number of somatic symptoms and generalised anxiety disorder scores of university students. CONCLUSION: Most of the university students are affected by anxiety during the COVID-19 pandemic and this effect is correlated with the frequency of somatic symptoms. In this context, it would be beneficial for universities to plan for acute and long-term psychological services and to cooperate with the government to provide timely crisis-oriented psychological services.
