Resistencia antibiótica y aspectos clínicos de Neisseria gonorrhoeae anorrectal en un hospital de CABA, Argentina / Antimicrobial resistance and clinical aspects in anorectal Neisseria gonorrhoeae in a hospital in CABA, Argentina

La infección por Neisseria gonorrhoeae (NG) es considerada de alta prioridad en salud pública, por su capacidad para desarrollar resistencia a la mayoría de los antibióticos empleados para tratarla. La presentación anorrectal suele ser asintomática y frecuente en hombres que tienen sexo con hombres (HSH). En Argentina, se recomienda terapia antibiótica dual (ceftriaxona+azitromicina/doxiciclina) como primera línea empírica. Este estudio observacional y retrospectivo se realizó para evaluar el porcentaje de positividad de NG anorrectal, el perfil de sensibilidad a penicilina, tetraciclina, ciprofloxacina, ceftriaxona, cefixima y azitromicina, así como los aspectos clínicos-epidemiológicos de los pacientes atendidos entre 20/10/2015 y 20/03/2020 en consultorios coloproctológicos de un hospital público. Se detectaron 55/436 hisopados rectales positivos para NG (13%). El 95% era HSH y 71%, VIH+. En 18/55 NG fue la única infección. Las co-infecciones más frecuentes: HPV (38%) y C. trachomatis (35%). La sensibilidad a cefalosporinas de espectro extendido (CEE) y a azitromicina fueron 100% y 98%, respectivamente. Se observó la emergencia local de los primeros cinco aislamientos de NG anorrectal con sensibilidad reducida (SR) a CEE, el primer aislamiento con categoría no-sensible a azitromicina y otro con SR a azitromicina concomitantemente con SR a CEE. Aunque el uso de terapia empírica dual sigue siendo adecuado para nuestra institución, se observó la emergencia de aislamientos con SR y NS a las drogas de primera línea, evidenciando la importancia de la vigilancia epidemiológica a nivel local para definir los tratamientos empíricos.

Neisseria gonorrhoeae (NG) infection is considered a high public health priority because of its ability to develop resistance to most of the antibiotics used to treat it.The anorectal presentation is generally asymptomatic and frequent in men who have sex with men (MSM). In Argentina, dual therapy (ceftriaxone+azithromycin/doxycycline) is recommended as first line empiric therapy.This observational and retrospective study was conducted to evaluate the percentage of anorectal NG positivity, the susceptibility profile to penicillin, tetracycline, ciprofloxacin, ceftriaxone, cefixime and azithromycin, as well as the clinical-epidemiological aspects of patients attended between 20/10/2015 and 20/03/2020 in coloproctology of a public hospital.We detected 55/436 positive rectal swabs for NG (13%). 95% were MSM and 71% were PLHIV. In 18/55 NG was the only infection. The most frequent co-infections: HPV (38%) and C. trachomatis (35%).Susceptibility to extended-spectrum cephalosporins (ESCs) and azithromycin was 100% and 98%, respectively. Local emergence of the first five anorectal NG isolates with decreased susceptibility (DS) to ESCs, the first isolate with nonsusceptible category to azithromycin and another with DS to azithromycin concomitantly with DS to ESCs were observed.Although the use of dual empirical therapy continues to be adequate for our institution, the emergence of isolates with DS and NS to first-line drugs was observed, evidencing the importance of epidemiological surveillance at the local level to define empirical treatments

Genetic variations among the isolates of Bipolaris Maydis based on phenotypic and molecular markers

Abstract Maydis leaf blight, caused by Bipolaris maydis, is an important disease of maize crop in Khyber Pakhtunkhwa (KP) Pakistan. Fifteen isolates of the pathogen, collected across KP, were studied for variability based on phenotypic and molecular markers. Significant variability among the isolates was observed when assessed using phenotypic traits such as radial growth, spore concentration, fungicide sensitivity and virulence. The isolates were classified into six culture groups based on colour, texture and margins of the colony. Conidial morphology was also variable. These were either straight or slightly curved and light to dark brown in colour. Fungicide test showed significant variation in the degree of sensitivity against Carbendazim. Isolate Bm8 exhibited maximum radial growth on carbendazim spiked plates. Conversely, isolate Bm15 showed the lowest radial growth. Variations in virulence pattern of the isolates were evident when a susceptible maize variety Azam was inoculated with spores of B. maydis. Genetic variability amongst the isolates was also estimated by RAPD as well as sequencing of ITS region. The RAPD dendrogram grouped all the isolates into two major clusters. Average genetic distance ranged from 0.6% to 100%, indicating a diverse genetic gap among the isolates. Maximum genetic distance was found between isolates Bm9 and Bm10 as well as Bm2 and Bm8. Conversely, isolates Bm13 and Bm15 were at minimum genetic distance. Phylogenetic dendrogram based on sequencing of ITS region grouped all the isolates into a single major cluster. The clusters in both the dendrogram neither correlate to the geographical distribution nor to the morphological characteristics.

Resumo A ferrugem das folhas de maydis, causada por Bipolaris maydis, é uma doença importante da cultura do milho em Khyber Pakhtunkhwa (KP), Paquistão. Quinze isolados do patógeno, coletados em KP, foram estudados quanto à variabilidade com base em marcadores fenotípicos e moleculares. Variabilidade significativa entre os isolados foi observada quando avaliada por meio de características fenotípicas, como crescimento radial, concentração de esporos, sensibilidade a fungicida e virulência. Os isolados foram classificados em seis grupos de cultura com base na cor, textura e margens da colônia. A morfologia dos conídios também foi variável. Estes eram retos ou ligeiramente curvos e de cor marrom-claro a escuro. O teste de fungicida mostrou variação significativa no grau de sensibilidade ao carbendazim. O isolado Bm8 exibiu crescimento radial máximo em placas com adição de carbendazim. Por outro lado, o isolado Bm15 apresentou o menor crescimento radial. As variações no padrão de virulência dos isolados foram evidentes quando uma variedade de milho suscetível Azam foi inoculada com esporos de B. maydis. A variabilidade genética entre os isolados também foi estimada por RAPD, bem como sequenciamento da região ITS. O dendrograma RAPD agrupou todos os isolados em dois grupos principais. A distância genética média variou de 0,6% a 100%, indicando uma lacuna genética diversa entre os isolados. A distância genética máxima foi encontrada entre os isolados Bm9 e Bm10 e também entre Bm2 e Bm8. Por outro lado, os isolados Bm13 e Bm15 estavam a uma distância genética mínima. O dendrograma filogenético baseado no sequenciamento da região ITS agrupou todos os isolados em um único aglomerado principal. Os agrupamentos em ambos os dendrogramas não se correlacionam com a distribuição geográfica nem com as características morfológicas.

The Prevention and Treatment of Pulmonary Nodules “Nodule-cancer Transformation” Based on the View of “Disease with Latent Pathogen Induced by a New Pathogen” / 中医杂志

As one of the pathogenic mechanisms contained in The Inner Canon of Yellow Emperor （《黄帝内经》）， “disease with latent pathogen induced by a new pathogen” means that the induced new pathogen resulted to a combination of the latent previous pathogen and the new pathogen， which caused the disease. Based on this， it is believed that the change of “nodule-cancer transformation” of pulmonary nodules is actually based on the deficiency of original qi， and the new pathogen induces the latent pathogens like phlegm coagulation， qi stagnation， blood stasis， toxicity， so healthy qi can not drive the pathogens out， and the long-time detention generated into cancerous turbidity， and deve-loped into cancerous tumour at the end. Therefore， based on the three-stage treatment of unformed cancer， dense cancerous toxin， and developed cancer， the clinical practice applied six methods of clearing， expelling， dissipating， tonifying， harmonizing， and transforming， taking into account both the manifestation and root cause， moving the treatment window of pulmonary nodules forward， attacking the pathogens when the toxin was not yet overbearing， supporting the healthy qi before declining， delaying the process of nodules-cancer transformation， and providing ideas for the prevention and treatment of pulmonary nodules “nodule-cancer transformation” in traditional Chinese medicine.

Prevalencia de infección por Chlamydia trachomatis y relación con el perfil de conductas sexuales en adolescentes y mujeres jóvenes de la Provincia de Osorno, Chile

Introducción: La infección por Chlamydia trachomatis es la ITS bacteriana más frecuente del mundo. En el cervix se presenta mayormente de forma asintomática y afecta especialmente a mujeres jóvenes y adolescentes. Puede producir daño permanente en el tracto reproductor femenino, se asocia a parto prematuro, infecciones neonatales transmitidas vía vertical y mayor riesgo de adquirir otras ITS como VIH Y VPH. Por estos motivos se han establecido estrategias de tamizaje para detectar y tratar precozmente la infección asintomática por C. trachomatis en diferentes países. En nuestro país no contamos con un programa nacional de tamizaje. Objetivo: Determinar la prevalencia de infección asintomática por Chlamydia trachomatis en mujeres entre 12 y 21 años de la Provincia de Osorno, Región de Los Lagos, Chile. Pacientes y Métodos: Se desarrolló un estudio de diseño transversal con una cohorte única de mujeres adolescentes y jóvenes consultantes en el Policlínico de Alto Riesgo Obstétrico y de Ginecología Infantil y Adolescente, del Hospital Base de Osorno, entre enero de 2019 y enero 2020. Se determinó el estado de infección asintomática mediante RPC en tiempo real para C. trachomatis. Se realizó una encuesta a fin de determinar características demográficas, hábitos y conductas sexuales de las pacientes estudiadas. Resultados: Fueron reclutadas 124 mujeres entre 12 a 21 años de edad, de las cuales, 36 (29,3%) se encontraban embarazadas al momento del estudio. La prevalencia de infección asintomática por C. trachomatis fue de 14/124 (11,3%). En las mujeres gestantes se encontraron 6/36 (16,7%) casos positivos de infección por C. trachomatis y 8/88 (9,1%) en las no gestantes. Existe una mayor frecuencia de infección asintomática a menor edad de inicio de actividad sexual (33,3% en aquellas que inician entre 11-12 años vs. 16,2% en las que inician entre 1314 años, 7,4% entre 15-16 y 8% entre 17-21 años; p < 0,05). Esta tendencia no fue observada al comparar el estado de infección con el tiempo de vida sexual activa. Sólo 15,7% de las pacientes utilizó preservativo en todas sus relaciones sexuales. Discusión: La infección asintomática por C. trachomatis es frecuente en las mujeres adolescentes y jóvenes sexualmente activas. Las pacientes con inicio más temprano de la actividad sexual coital (bajo 13 años de edad) podrían estar en mayor riesgo. Se requiere con urgencia establecer la frecuencia nacional de infección para desarrollar una estrategia sanitaria para su pesquisa y manejo oportuno en nuestro país.

Background: Chlamydia trachomatis infection is the world most common bacterial STI. At uterine cervix it presents mostly asymptomatically and especially affects young women and adolescents. It can cause permanent damage to the female reproductive tract and is associated with premature birth, connatal infections and increased risk of acquiring other STIs such as HIV and HPV. For these reasons, other countries have established screening strategies to detect and treat asymptomatic C. trachomatis infection. Our country don't have a national screening program. Aim: To determine the prevalence of C. trachomatis asymptomatic infection in adolescent and young women in Osorno province, Los Lagos Region, Chile. Methods: A crosssectional study was performed in adolescent and young women who consult at Hospital Base Osorno in the MaternoFetal and PediatricAdolescent Gynecology ambulatory clinics, between January 2019 and January 2020. The status of asymptomatic infection was determined by PCR for C. trachomatis. A survey was carried out to determine the demographic characteristics, habits and sexual behaviors. Results: 124 women between 12 and 21 years of age were recruited, of which 36 (29,3%) were pregnant at the time of the study. The prevalence of asymptomatic infection by C. trachomatis was 11.3.%. In pregnant women, there were 6/36 (16.7%) positive cases for C. trachomatis and 8/88 (9.1%) in nonpregnant women. We found a higher frequency of asymptomatic infection at younger age of first sexual intercourse (33% in adolescents at 11-12 years old vs. 16.2% at 13-14, 7.4% at 15-16 and 8% at 17-21; p<0.05). Only 15.7% of the patients utilized condoms in all their intercourses. Discussion: Asymptomatic C. trachomatis infection is common in adolescent and young women, with a higher risk in those who onset sexual activity at an early age (less than 13 years old). It is urgently required to determine the national frequency of asymptomatic C. trachomatis infection to develop a national strategy for screening and timely treatment.

The molecular investigations on the subgenus Artemisia Less. of the genus Artemisia L. (Asteraceae) in Turkey / Investigações moleculares sobre o subgênero Artemisia Less. do gênero Artemisia L. (Asteraceae) na Turquia

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.

Diversity of Endophytes in Panax quinquefolium Root / 中国实验方剂学杂志

ObjectiveTo analyze the community structure of endophytes in Panax quinquefolium root and explore the dominant endophytic bacteria and fungi， to provide scientific basis for the establishment of endophytic microbial bank in P. quinquefolium root. MethodInternal Transcribed Spacer （ITS） sequencing and 16S sequencing were performed on six P. quinquefolium root samples collected from Wendeng， Shandong province on PacBio Sequel Ⅱ. ResultA total of 8 phyla， 11 classes， 23 orders， 27 families and 53 genera of endophytic bacteria were identified in P. quinquefolium root， among which an unidentified Burkholderiaceae and an unidentified Rhizobiaceae were dominant. A total of 9 phyla， 23 classes， 35 orders， 43 families and 48 genera of endophytic fungi were identified in P. quinquefolium root， among which an unclassified Helotiales and Pseudogymnoascus were dominant. The community structure of endophytic bacteria revealed that the roots were selectively enriched with nitrogen-fixing bacteria such as unidentified Rhizobiaceae， Bradyrhizobium and Herbaspirillum， which suggested that nitrogen is important for the growth of P. quinquefolium root. The community structure of endophytic fungi indicated that P. quinquefolium in Shandong province might be infected by unclassified Helotiales. ConclusionThere is a rich diversity of endophytic bacteria and fungi in P. quinquefolium root， which provides scientific basis for studying the interaction of the plant with endophytic microorganisms and screening the endophytes to promote the growth of P. quinquefolium root.

Distinguishing between Artemisia stolonifera and A. argyi by specific PCR of leaves and non-glandular trichomes / 中国中药杂志

Artemisia stolonifera is a relative of A. argyi. The two species are difficult to be distinguished due to the similarity in leaf shape and have even less distinctive features after processing. This study aims to establish a method to quickly distinguish between them. At the same time, we examined the reasonability and applicability of the specific polymerase chain reaction(PCR) method. The C/T single nucleotide polymorphism was detected at the position 202 of the sequence, based on which specific primers were designed to identify these two species. The PCR with the specific primer JNC-F and the universal primer ITS3R produced a specific band at 218 bp for A. argyi and no band for A. stolonifera, which can be used to detect at least 3% of A. argyi samples mixed in A. stolonifera samples. The PCR with the specific primer KY-F and the universal primer ITS3R produced a specific band at 218 bp for A. stolonifera and no band for A. argyi, which can be used to detect at least 5% of A. stolonifera samples mixed with A. argyi. The limit of detection of the established method was 5 ng DNA. The established PCR method can accurately distinguish between A. stolonifera and A. argyi, which provides an experimental basis for the quality control of A. stolonifera and determines whether the herbs are adulterated.

Introducción. Las infecciones de transmisión sexual (ITS) son y seguirán siendo un serio problema de salud pública en todo el mundo según los datos de la OMS, con el agravante que la mayoría de los casos son asintomáticos y, además, no existe otro reservorio distinto al humano. El diagnóstico se puede realizar con pruebas tradicionales y moleculares, estas últimas incluyen la reacción en cadena de la polimerasa (PCR), de las cuales existen varios tipos, entre ellas, la PCR múltiple que tiene la capacidad de detectar ITS polimicrobianas a partir de una sola muestra. El objetivo de este estudio fue establecer cuáles fueron las infecciones de transmisión sexual más frecuentes en diferentes grupos de pacientes, así como determinar la utilidad del uso de la técnica de PCR múltiple en el diagnóstico de las ITS. Metodología. Se trata de un estudio observacional de corte transversal realizado entre los años 2021 y 2022 con pacientes que acudieron al servicio de diagnóstico del Laboratorio Clínico VID por sospecha de ITS. Las muestras recolectadas fueron evaluadas utilizando una prueba comercial basada en la técnica de PCR múltiple e hibridación. Las muestras procesadas fueron: orina e hisopados de endocérvix, uretra, recto, faringe y úlceras. Resultados. Se estudiaron 1.027 pacientes, de estos, 228 (22,2 %) fueron positivos para diferentes agentes de trasmisión sexual, distribuidos así: 50 (21,9 %) mujeres, 129 (56,6 %) hombres heterosexuales y 49 (21,5 %) hombres que tenían sexo con hombres (HSH). La edad promedio de las mujeres fue 30 años, y la de ambos grupos de hombres fue 36 años. Los microorganismos más frecuentemente identificados en mujeres fueron: C. trachomatis (A-K) en 28,6 %, seguido de virus herpes simplex tipo 2 (VHS-2) en 26,8 % y N. gonorrhoeae en 17,9 %. En hombres heterosexuales fueron C. trachomatis (A-K) en 37,5 %, N. gonorrhoeae en 21,5 % y VHS-2 en 18,7 %. En HSH fueron C. trachomatis (L1-L3) en 32,7 %, seguido de N. gonorrhoeae en 27,6 %, y de C. trachomatis (A-K) y VHS-2, ambos en 13,8 %. En 11 hombres heterosexuales, 8 HSH y en 6 mujeres, se identificó infección polimicrobiana. Conclusiones. C. trachomatis (A-K) fue el microorganismo más prevalente causante de ITS, seguido de N. gonorrhoeae en ambos grupos de hombres, y de VHS-2 en las mujeres, muy similar a lo reportado a nivel mundial. La prueba de PCR múltiple permite la detección de infecciones polimicrobianas comúnmente asociadas a ITS y el diagnóstico es preciso y confiable, incluso en pacientes asintomáticos

Sexually transmitted infections (STIs) are and will continue to be a serious public health problem throughout the world according to WHO data, with the aggravating factor that most cases are asymptomatic and, furthermore, there is no other reservoir other than humans. The diagnosis can be made with traditional and molecular tests, the latter include the polymerase chain reaction (PCR), of which there are several types, among them, multiplex PCR that has the capacity to detect polymicrobial STIs from a single sample. The objective of this study was to establish which were the most frequent sexually transmitted infections in different groups of patients, as well as to determine the usefulness of the multiplex PCR technique in the diagnosis of STIs. Methodology. This is an observational, cross-sectional study carried out between 2021 and 2022 with patients who attended the VID Clinical Laboratory for suspected STIs. The collected samples were evaluated using a commercial test based on the multiplex PCR technique and hybridization. The samples processed were: urine and swabs from endocervix, urethra, rectum, pharynx, and ulcers. Results. The study included 1,027 patients, of these, 228 (22.2%) were positive for different sexually transmitted agents, distributed as follows: 50 (21.9%) women, 129 (56.6%) heterosexual men and 49 (21.5%) men who had sex with men (MSM). The average age of the women was 30 years, and that of both groups of men was 36 years. The microorganisms most frequently identified in women were: C. trachomatis (A-K) in 28.6%, followed by herpes simplex virus type 2 (HSV-2) in 26.8% and N. gonorrhoeae in 17.9%. In heterosexual men they were C. trachomatis (A-K) in 37.5%, N. gonorrhoeae in 21.5% and HSV-2 in 18.7%. In MSM they were C. trachomatis (L1-L3) in 32.7%, followed by N. gonorrhoeae in 27.6%, and C. trachomatis (A-K) and HSV-2, both in 13.8%. Polymicrobial infection was identified in 11 heterosexual men, 8 MSM, and 6 women. Conclusions. C. trachomatis (A-K) was the most prevalent STI-causing microorganism, followed by N. gonorrhoeae in both groups of men, and HSV-2 in women, very similar to that reported worldwide. The multiplex PCR test allows the detection of polymicrobial infections commonly associated with STIs and the diagnosis is accurate and reliable, even in asymptomatic patients

As inscrições foram realizadas através de um formulário Google, amplamente divulgado nas mídias sociais: Instagram e WhatsApp. O evento foi realizado no dia 5 de maio de 2022, de forma presencial na Universidade Paranaense (UNIPAR), Umuarama - PR. Foram conduzidas duas palestras, a primeira por uma médica ginecologista e a segunda por uma psicóloga. DISCUSSÃO: O público foi extremamente receptivo com o evento, demonstrando grande satisfação com a forma de abordagem utilizada pelas palestrantes, além da fala clara e bastante didática a respeito de como se deve abordar esse tema frente ao paciente e qual o comportamento mais adequado para o profissional da saúde. CONCLUSÃO: Os pacientes, muitas vezes, já fragilizados e com receio do estigma buscam o acolhimento e apoio dos profissionais da saúde. O evento proporcionou esse direcionamento e orientação da abordagem das IST's e sexualidade em consultório. Portanto, o assunto faz-se de extrema relevância e destaca a necessidade de capacitação desses profissionais por meio da promoção de demais atividades que compreendam a saúde sexual.

Ethics and Bioethics are basic principles that underlie the work of health professionals, considered extremely important in face of the dilemmas faced by this team during the approach to sexuality and Sexually Transmitted Infections (STIs). The event aimed to address the direction of a relationship of trust with the patient and the health professional, making them comfortable and safe when sharing personal and confidential information. Given the above, this report aims to describe the experiences of this event and highlight the importance of ethics, bioethics, and medical confidentiality for the exercise of the profession. REPORT: The activity "STIs and Sexuality: How to approach it in the doctor's office" was conceived during a meeting of the Sexual and Reproductive Rights Axis, and carried out with the collaboration of 8 (eight) coordinators. The registrations were made through a Google form, widely publicized on social media: Instagram and WhatsApp. The event was held on May 5, 2022, in person at the Universidade Paranaense (UNIPAR), Umuarama - PR. Two lectures were conducted, the first by a gynecologist and the second by a psychologist. DISCUSSION: The audience was extremely receptive to the event, showing great satisfaction with the approach used by the lecturers, besides the clear and very didactic speech on how this theme should be approached in front of the patient and what is the most appropriate behavior for the health professional. CONCLUSION: Patients, many times already weakened and afraid of the stigma, seek the welcoming and support from health professionals. The event provided this direction and orientation on how to approach STIs and sexuality in the doctor's office. Therefore, the subject is extremely relevant and highlights the need for training of these professionals through the promotion of other activities that understand sexual health.

Community structure of endophytic fungi in roots and leaves of Fagopyrum mill and Avena sativa in a Chinese northern cold region

In order to explore the endophytic fungi of Fagopyrum Mill and Avena sativa, Illumina Miseq high-throughput sequencing was used to analyze the community structure and diversity of endophytic fungi in leaves and roots of buckwheat and oat at the mature stage. The results of community structure showed that there were 205 operational taxonomic units (OTUs) in buckwheat roots and 181 OTUs in buckwheat leaves based on 97% sequence similarity level. There were 152 OTUs and 127 OTUs in the root and the leaf of oat, respectively. At the phylum level, Ascomycota and Basidiomycota were the dominant endophytic fungi in buckwheat roots and leaves, while Ascomycota was the dominant endophytic fungus in oat roots and leaves. Alpha diversity analysis showed that the Ace index, Chao index and Shannon index of buckwheat roots were higher than that of buckwheat leaves, and the three indices of oat roots were also higher than that of oat leaves, indicating that the richness and diversity of endophytic fungi community in roots were higher than that in leaves. Biomarkers were found by significant difference analysis in buckwheat and oat. The endophytic functional groups of buckwheat and oat were mainly distributed in Pathotroph and Saprotroph. The results of this study laid a foundation for fully exploiting the dominant endophytic fungal resources of buckwheat and oat and further developing microbial fertilizers.

The molecular investigations on the subgenus Artemisia Less. of the genus Artemisia L. (Asteraceae) in Turkey / Investigações moleculares sobre o subgênero Artemisia Less. do gênero Artemisia L. (Asteraceae) na Turquia

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.

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.

Dietary exposure assessment of deoxynivalenol in wheat flour and its products sold in Shanghai / 上海预防医学

ObjectiveTo investigate the pollution level of deoxynivalenol （DON） in wheat flour and its products sold in Shanghai， and to assess the health risks of DON exposure for residents in Shanghai who ingested DON from wheat flour and its products. MethodsRisk monitoring data of DON in wheat flour and its products sold in Shanghai from 2017 to 2021 were combined with the consumption data of wheat flour and its products by Shanghai residents. A probabilistic assessment method was used to assess dietary exposure of DON in wheat flour and its products. ResultsThe overall detection rate of DON in wheat flour and its products was 77.3% （1 041/1 347）， with a mean concentration of 226.3 μg·kg-1， P50 of 130.0 μg·kg-1 and a maximum value of 3 080.0 μg·kg-1. The mean daily exposure and 95th percentile daily exposure （by body weight） of DON from wheat flour and its products in Shanghai residents were 0.279 μg·kg-1 and 1.146 μg·kg， accounting for 27.9% and 114.6% of the daily tolerable intake of DON TDI， 1 μg·kg， respectively. The probability assessment results indicated that 6.1% of the whole population in Shanghai had DON exposure exceeding the TDI value. Among them， 12.8% of the population aged 6 years old and below， 16.4% of the population aged between 7 and 17 years old， 3.9% of the population aged between 18 and 59 years old and 3.2% of the population aged 60 years old and above exceeded the TDI value for daily DON exposure through wheat flour and its products. ConclusionCertain populations in Shanghai may face certain health risks from daily DON intake wheat flour and its products. Special attention should be paid to the health risk of daily DON exposure through wheat flour and its products for individuals age below 18 years old .

Analysis of the nail microbiome in patients with onychomycosis by high-throughput sequencing of 16S rDNA and internal transcribed spacer regions / 中华皮肤科杂志

Objective:To investigate differences in bacterial and fungal microbiome between infected nails and healthy nails among patients with onychomycosis.Methods:Nail scraping samples were collected from infected nails and healthy nails of 31 patients with onychomycosis, who visited Dalian Dermatosis Hospital from August 2020 to July 2021. The total DNA of nail microbiota was extracted, and the V3-V4 regions of the bacterial 16S rDNA gene and the fungal internal transcribed spacer (ITS) region were amplified and sequenced using Illumina technology. The USEARCH and mothur softwares were used for data cluster analysis to obtain the operational taxonomic units (OTUs) , Wilcoxon rank sum test was used to analyze α diversity, analysis of similarities (ANOSIM) was performed to analyze β diversity, linear discriminant analysis of effect size (LEfSe) was performed to evaluate the species difference.Results:Among the 31 patients with onychomycosis, 16 were males and 15 were females. According to the age, they were divided into young group (18 - 35 years old, 10 cases) , middle-aged group (36 - 60 years old, 11 cases) , and elderly group (over 60 years old, 10 cases) . As the α-diversity analysis revealed, the infected nail group showed significantly decreased Shannon index ( W = 290, P = 0.007) , but significantly increased Simpson index ( W = 663, P = 0.010) compared with the healthy nail group, suggesting that the diversity and evenness of bacterial communities were lower in the infected nail group than in the healthy nail group; however, there was no significant difference in the diversity of fungal communities between the infected nail group and healthy nail group. The β-diversity analysis based on the unweighted-UniFrac distance matrix showed no significant difference in the fungal or bacterial community composition between the infected nail group and healthy nail group (bacterial communities: R = 0.0052, P = 0.331; fungal communities: R = 0.0036, P = 0.337) ; the β-diversity analysis based on the weighted-UniFrac distance matrix showed significant differences in the abundance of bacterial and fungal communities between the two groups (both P = 0.001) . In terms of the species composition, the bacterial flora with significantly decreased abundance in the infected nail group compared with the healthy nail group included Bacteroidetes, Proteobacteria, Betaproteobacteria, Burkholderiales, Ralstonia, Sphingomonas and Streptococcus, while the abundance of Bacilli, Bacillales and Staphylococcus was significantly higher in the infected nail group than in the healthy nail group. Compared with the healthy nail group, the fungal flora with significantly increased abundance in the infected nail group included Eurotiomycetes, Onygenales, Leotiomycetes-ord-incertae-sedis, Arthrodermataceae, Periconia, Erysiphe, Tilletiopsis, Trichophyton, Erysiphe cruciferarum, Trichophyton rubrum, Malassezia sympodialis, while the abundance of Saccharomycetes, Saccharomycetales, Saccharomycetaceae, Dothioraceae, Candida and Alternaria was significantly lower in the infected nail group than in the healthy nail group. Conclusion:The diversity and abundance of bacterial communities significantly differed between infected nails and healthy nails among patients with onychomycosis, while only the abundance of fungal communities differed between the two groups, and perhaps there was correlations between some bacterial and fungal communities.

Colombian adolescents fail in knowledge regarding HIV and other sexually transmitted infections / Adolescentes colombianos fracasan en conocimientos sobre VIH y otras infecciones de transmisión sexual

Abstract Introduction/objective: Sexually transmitted infections (STIs) -HIV included- are a major problem in Latin America, mainly in Colombia. In 2021, 17647 cases were reported, which compared to the previous year showed an increase of 29.7%. The main aim of this study was to assess the knowledge regarding HIV and other STIs among the adolescent population in Colombia. Method: A total of 2012 Colombian adolescents between 12-19 years of age participated in this study. The HIV and Other Sexually Transmitted Infections Knowledge Scale (KSI), a self-report measure, was administered. Results: The results showed moderate to low general knowledge (M = 9.90, SD = 4.64) regarding HIV and other STIs. Adolescents did not know if a tongue-kiss led to an HIV infection (75%), or whether both the vaginal ring and the IUD were effective methods for preventing HIV/AIDS (82%). Results showed better scores in knowledge regarding HIV transmission (84%), HIV testing (66%), and condom use to prevent HIV infection (71%). Conclusions: Significant differences were observed in HIV/STIs knowledge between both sexes, but the effect magnitudes were small. Thus, these differences were neglected. This study contributes to understanding the state of knowledge and strengthening prevention strategies of professionals linked to the field of quality of life, education, and sexual healthcare in Colombia.

Resumen Introducción/objetivo: Las infecciones de transmisión sexual (ITS) y el VIH son un gran desafío en América Latina, principalmente en Colombia. Para el 2021 se reportaron 17 647 casos, que comparados con el 2019 muestran un incremento del 29.7 %. El objetivo principal de este artículo fue evaluar el conocimiento sobre el VIH y otras ITS en la población adolescente de Colombia. Método: En este estudio participaron un total de 2012 adolescentes colombianos con edades entre los 12 y los 19 años. Se administró la Escala de Conocimientos sobre el VIH y otras infecciones de transmisión sexual (KSI) y una medida de autoinforme. Resultados: Los resultados mostraron un conocimiento general de moderado a bajo (M = 9.90, SD = 4.64) sobre el VIH y otras ITS. Las adolescentes no sabían si un beso con lengua conducía a una infección por el VIH (75 %) o si tanto el anillo vaginal como el DIU eran métodos efectivos para prevenir el VIH/SIDA (82 %). Los resultados mostraron mejores puntuaciones en conocimientos sobre la transmisión del VIH (84 %), pruebas de detección del VIH (66 %) y uso de preservativos para prevenir la infección por el VIH (71 %). Conclusiones: Se observaron diferencias significativas en el conocimiento del VIH/ ITS entre ambos sexos, pero los tamaños del efecto fueron pequeños. Por tanto, estas diferencias fueron despreciadas. Este estudio contribuye a comprender el estado del conocimiento y a fortalecer las estrategias de prevención que realizan los profesionales vinculados al campo de la calidad de vida, la educación y la salud sexual en Colombia.

Distribución de virus de papiloma humano de alto riesgo oncogénico y otras infecciones de transmisión sexual en mujeres paraguayas con y sin virus de la inmunodeficiencia humana

El virus de papiloma humano de alto riesgo oncogénico (VPH-AR) es causa necesaria pero no suficiente para la ocurrencia de cáncer de cuello uterino (CCU). Mujeres portadoras del virus de inmunodeficiencia humana (VIH) presentan mayor riesgo de desarrollar lesiones precursoras del cáncer de cuello de útero, por ello, el objetivo del presente trabajo prospectivo de corte transversal fue determinar la frecuencia de VPH-AR y otras infecciones de transmisión sexual-ITS (condilomas, sífilis, virus del herpes simple, gonorrea, citomegalovirus, hepatitis B) en 218 mujeres con y sin VIH que acudieron al Programa Nacional de Lucha contra el SIDA (PRONASIDA) desde julio 2017 hasta marzo 2021. Se encontró que 16/54 (29,6%) mujeres VIH-positivas presentaron infección por VPH-AR en comparación a 41/164 (25%) mujeres VIH-negativas (p>0,05). En relación a la edad, mujeres VIH positivas presentaron una frecuencia comparable de infección por VPH-AR (30 años 30,2%), a diferencia de mujeres VIH negativas donde hubo una disminución significativa de la infección por VPH-AR luego de los 30 años (30 años 18,8%, p= 0,028). Esto podría explicarse por la inmunosupresión observada en mujeres VIH positivas que podría favorecer infecciones persistentes, sugiriendo que deben ser controladas más cercanamente. Además, se observó mayor frecuencia de otras ITS en mujeres VIH positivas (29,6% vs 15,8%, p=0,026), lo cual sugiere que aparte del monitoreo más cercano, es fundamental fortalecer la educación sobre factores de riesgo para la ITS sobre todo VPH y VIH, así como la realización de prevención primaria por vacunación contra el VPH.

High-risk human papillomavirus (HPV-HR) is a necessary but not sufficient cause for cervical cancer (CC). Women carriers of human immunodeficiency virus (HIV) present an increased risk for the development of cervical cancer precursor lesions, therefore, the objective of the present prospective cross-sectional study was to determine the frequency of HPV-HR and other sexually transmitted infections-STIs (condylomas, syphilis, herpes simplex virus, gonorrhoea, cytomegalovirus, hepatitis B) in 218 women with and without HIV who attended the Ministry of Health from July 2017 to March 2021. It was found that 16/54 (29.6%) HIV-positive women had HPV infection compared to 41/164 (25%) HIV-negative women (p>0.05). In relation to age, HIV-positive women had a comparable frequency of HPV infection (30 years 30.2%), unlike HIV-negative women whom above 30 years of age presented a significant decrease in HPV-AR infection (30 years 18.8%, p:0.028). This could be explained by the immunosuppression observed in HIV-positive women which could favour persistent infections, suggesting that they should be controlled more closely. In addition, other STIs were observed to be more frequent in HIV-positive women (29.6% vs 15.8%, p:0.026), which suggests that apart from closer monitoring, it is essential to strengthen education on risk factors for STIs, especially HPV and HIV, as well as the implementation of primary prevention by vaccination against HPV.
