Compromiso inmunológico en pacientes con síndrome de Down. Serie de casos / Immune compromise in patients with Down syndrome. A case series

El síndrome de Down, o trisomía 21, tiene una mortalidad mayor que la población general, debido principalmente a infecciones respiratorias. El objetivo de este trabajo es describir el compromiso inmunológico en una serie de casos de pacientes con síndrome de Down derivados a Inmunología por infecciones recurrentes o por hallazgo patológico de laboratorio, entre el 1 de junio de 2016 y el 31 de mayo de 2022. Se describe el compromiso de la inmunidad en 24 pacientes. Doce pacientes presentaron falla de respuesta a polisacáridos y recibieron quimioprofilaxis antibiótica y/o gammaglobulina sustitutiva. En 3 pacientes, se observó agammaglobulinemia con linfocitos B presentes y se indicó gammaglobulina sustitutiva. En 9 pacientes, se observó linfopenia T y en 1 paciente, compromiso inmune combinado.

Down syndrome, or trisomy 21, has a higher mortality than the general population, mainly due to respiratory tract infections. The objective of this study was to describe immune compromise in a series of cases of patients with Down syndrome referred to the Pediatric Immunology Section due to recurrent infections or pathological laboratory findings between 6/1/2016 and 5/31/2022. Here we describe immune compromise in 24 patients. Twelve patients failed to develop a polysaccharide response and received antibiotic chemoprophylaxis, or gamma globulin replacement therapy. Three patientsdeveloped agammaglobulinemia with presence of B cells and gamma globulin replacement therapy was indicated. Nine patients had T-cell lymphopenia and 1 patient, combined immune compromise.

Clinical application of non-invasive prenatal testing for twin pregnancies / 中华医学遗传学杂志

OBJECTIVE@#To evaluate the feasibility of non-invasive prenatal testing (NIPT) for the screening of fetal chromosome aneuploidies in twin pregnancies.@*METHODS@#A total of 2 745 women with twin-pregnancies were subjected for NIPT screening. Chromosomal karyotyping and chromosomal microarray analysis (CMA) were carried out on amniotic fluid samples from those with a high risk for fetal chromosome aneuploidies, and the diagnosis and pregnancy outcome were followed up. The sensitivity, specificity, positive predictive value and false positive rate of the NIPT were calculated.@*RESULTS@#Compared with other chromosomal abnormalities, NIPT had a higher efficacy for trisomy 21 and sex chromosomal aneuploidy (SCA) in twin pregnancies (with sensitivity being 100%, 100%, and specificity being 99.93%, 99.9%, respectively). It is difficult to evaluate the efficacy for trisomies 18 and 13 due to the limited data. For chromosome microdeletions and microduplications spanning 15 ~ 21 Mb, NIPT also had a certain detection rate. Compared with women with natural conception, NIPT had a higher detection rate for those with twin pregnancies by assisted reproduction (P < 0.05).@*CONCLUSION@#It is feasible to use NIPT for the detection of chromosome aneuploidies in women with twin pregnancies.

Prenatal diagnosis and outcome of pregnancy for women with high risks by screening of fetal free DNA from peripheral blood samples / 中华医学遗传学杂志

OBJECTIVE@#To analyze the results of prenatal diagnosis and outcome of pregnancy for women with a high risk for fetal aneuploidies.@*METHODS@#A total of 747 cases of prenatal diagnosis by amniocentesis due to high risks by non-invasive prenatal testing (NIPT) were selected from January 2015 to March 2022 in the Drum Tower Hospital Affiliated to Nanjing University Medical School. The amniotic fluid samples were subjected to chromosomal karyotyping and/or chromosomal microarray analysis. All cases were followed up by searching the birth information or telephone calls, and the results were recorded. 2 test or F test were used for comparing the difference between the groups.@*RESULTS@#Among the 747 pregnant women with a high risk by NIPT, 387 were true positives, and the overall positive predictive value (PPV) was 51.81%. The PPVs for trisomy 21 (T21), trisomy 18 (T18), trisomy 13 (T13) and sex chromosome aneuploidies (SCA) were 80.24% (199/248), 60% (48/80), 14% (7/50) and 38.97% (106/272), respectively. The PPV for T21 was significantly higher than T18 and T13 (χ2 = 85.216, P < 0.0001). The PPV for other chromosomal aneuploidies and copy number variations (CNVs) were 11.11% (5/45) and 40.74% (22/52), respectively. The PPV for increased X chromosomes was significantly higher than X chromosome decreases (64.29% vs. 22.22%, χ2 = 5.530, P < 0.05). The overall PPV for elder women (≥ 35 years old) was significantly higher than younger women (69.35% vs. 42.39%, χ2 = 49.440, P < 0.0001). For T21 and T18, the PPV of Z ≥ 10 group was significantly higher than that for 3 ≤ Z < 5 group or 5 ≤ Z < 10 group (P < 0.05). Among 52 cases with a high risk for CNVs, the PPV for the ≤ 5 Mb group was significantly higher than the 5 Mb < CNVs < 10 Mb or > 10 Mb groups (60% vs. 30%60% vs. 23.53%, P < 0.05). Among the 387 true positive cases, 322 had opted for induced labor, 53 had delivered with no abnormal growth and development, and 12 were lost during the follow-up.@*CONCLUSION@#The PPVs for common chromosomal aneuploidies are related to the age and Z value of the pregnant women, which were higher in the elder group and higher Z value group. In addition, the PPV is associated with high risk types. The PPV for T21 was higher than T18 and T13, and that for 45,X was lower than 47,XXX, 47,XYY or 47,XXY syndrome. NIPT therefore has relatively high PPVs for the identification of chromosomal CNVs.

Para ajustar la búsqueda al objeto de estudio, se estableció una serie de criterios de inclusión: i) cualquier tipo de documento científico relacionado con la temática; ii) manuscritos que indiquen, en el cuerpo del texto, al menos una descripción de los alumnos con SD de una longitud mínima de 50 palabras; iii) documentos realizados en inglés, español y/o portugués; y, iv) manuscritos que permitan obtener el texto completo; se obtuvo un total de 9 documentos. Los resultados mostraron una escasez de documentos en relación con el ámbito de estudio, como consecuencia de ser una temática muy específica. Asimismo, los manuscritos incluidos en esta revisión reportan que los beneficios que podrían obtenerse de la danza para el alumnado con SD están relacionados con la conciencia y el control postural, la mejora de aspectos sociales y mejoras a nivel cognitivo y emocional, así como el disfrute. Por ello, se recomienda ampliar el número de investigaciones futuras relacionadas con la danza en el sistema educativo y, concretamente, en la etapa de educación infantil, debido a los múltiples beneficios que aporta al alumnado con discapacidad.

Abstract Dance is a physical/sports and artistic activity appropriate to the comprehensive development of students, and can be considered as a means to promote inclusion. Thus, the objective of this study was to carry out a narrative review related to the benefits of dance in students with Down Syndrome (DS) in the child education stage. In order to carry out the search of documents, the keywords "Child Education", "Dance", and "Down Syndrome" were used. Manuscripts were searched in the Web of Science, Scopus, SPORTDiscus and PubMed data bases, up to January, 2023. In order to adjust the search of the object of study, a series of inclusion criteria was established: i) any type of scientific document relating to the topic; ii) manuscripts indicating, within the text body, at least one description of the students with DS that is at least 50 words in length; iii) documents written in English, Spanish and/or Portuguese; and iv) manuscripts that allow to obtain the full text. A total 9 documents were obtained. The results showed a scarcity of documents concerning the domain of study, as a result of this being a very specific topic. Similarly, the manuscripts included in this review report that the benefits that could derive from dance for students with DS have to do with posture awareness and control, the improvement of social aspects and improvements of a cognitive and emotional nature, as well as enjoyment. Therefore, it is recommended to expand the number of future research projects related to dance in the educational system, and concretely in the child education stage, due to the multiple benefits this brings to students with disabilities.

Purpose: to verify if the age of children with Trisomy 21 and the time of use per day of the stimulating palatal plate influence the child's adaptation to the plate, the orofacial myofunctional changes perceived by the parents, and the family's satisfaction, after four months of treatment. Methods: 14 parents or legal guardians of children with Trisomy 21, aged between 3 and 20 months, participated in the study. Treatment with the stimulating palatal plate was carried out for four months. The child's adaptation to the plate, the orofacial myofunctional changes perceived by the parents, and the families' satisfaction with the treatment were investigated through a questionnaire prepared by the research authors and answered by the mothers after four months of treatment. Results: The mean age of the children who participated in the study was 10 months and the standard deviation was 4.9 months. The results of the questionnaire indicated an association between age and lip posture, reported by parents, during the use of the stimulating palatal plate, and all children under 10 months maintained lip closure, according to the parents, during the use of the plate. Age was also associated with satisfaction with the service, as the mothers of younger children were more satisfied. Conclusion: The study results indicate an association between age and lip posture, reported by the parents, during the use of the plate, and between age and satisfaction with the service. Thus, it suggests that early treatment with the stimulating palatal plate benefits children with Trisomy 21. (AU)

Avaliação e intervenção responsiva e integrativa na criança com distúrbio alimentar pediátrico com Trissomia do 21: Relato de caso / Responsive and integrative assessment and intervention in children with pediatric feeding disorder with Trisomy 21: A case report / Evaluación e intervención receptiva e integradora en un niño con trastorno alimentario pediátrico con Trisomía 21: Reporte de caso

Na criança com Trissomia do 21 a dificuldade alimentar pode estar presente. Alguns sinais são as alterações na habilidade motora-oral, no processamento sensorial, tempo elevado das refeições, recusa alimentar prolongada e falta de autonomia. Ainda pouco se discute sobre as dificuldades alimentares e seu processo terapêutico nesta população. O objetivo deste estudo foi descrever a avaliação e intervenção fonoaudiológica e da terapia ocupacional na dificuldade alimentar de uma criança com Trissomia do 21 com o uso de estratégias de alimentação responsiva e integrativa. Criança 3 anos e 2 meses, sexo masculino. Avaliação fonoaudiológica demonstrou criança com distúrbio alimentar pediátrico, caracterizado por atraso na habilidade motora-oral, baixa percepção intraoral e comportamento alimentar altamente seletivo. Na avaliação da terapia ocupacional verificou-se perfil sensorial alterado. Na fonoterapia foram trabalhados aspectos como a percepção do alimento, ritmo e o tempo de alimentação. Na terapia ocupacional, o objetivo foi adequar nível de alerta, favorecer a independência e o desenvolvimento psicomotor. Após a intervenção, a reavaliação fonoaudiológica demonstrou que houve ampliação do cardápio, melhora da percepção, da habilidade motora intraoral, aceitação de diferentes utensílios e modos de apresentação do alimento, autonomia e prazer nas refeições. A reavaliação da terapia ocupacional mostrou um nível de alerta e atenção mais adequado, uso das mãos e dedos de maneira mais funcional para se alimentar. Foram observadas evoluções positivas em relação à intervenção fonoaudiológica e da terapia ocupacional na dificuldade alimentar de uma criança com Trissomia do 21 com o uso de estratégias de alimentação responsiva e integrativa. (AU)

In children with Trisomy 21 feeding difficulty can be observed, such as changes in oral motor skills, sensory processing, longer mealtimes, food refusal, lack of autonomy and others. However, there is little discussion about feeding difficulties and rehabilitation process in this population. This study aimed to describe speech-language and occupational therapy assessment and intervention in feeding difficulties in a 3-year and 2-month-old male child with a diagnosis of Trisomy 21. Speech-language pathology assessment found that the child had feeding difficulties, delay in oral motor skills, low intraoral perception and acceptance, while the occupational therapy assessment showed an altered sensory profile. The speech-language pathology sessions included aspects such as food perception, rhythm and feeding time. In turn, occupational therapy sessions aimed to adjust the alertness level, promote independence and psychomotor development. After the intervention, the speech-language pathology reassessment showed that there was an expansion of the menu for the ingestion, improvement in perception and intraoral motor skills, acceptance of different utensils and food presentation modes, autonomy and pleasure in meals. The reassessment of occupational therapy showed a better level of alertness and attention, more functional use of hands and fingers to eat. Therefore, a positive progress was observed in the feeding difficulty of a child with Trisomy 21 after a speech-language pathology and occupational therapy intervention with the use of responsive and integrative feeding strategies.

Comunicação do Diagnóstico da Síndrome de Down: Experiências de Mães e Médicos / Communication of Down Syndrome Diagnosis: Experiences of Mothers and Doctors / Comunicación del Diagnóstico del Síndrome de Down: Experiencias de Madres y Médicos

O estudo teve como objetivo conhecer as experiências de mães e médicos em relação ao comunicado do diagnóstico da síndrome de Down (SD). Trata-se de uma pesquisa exploratória e transversal, com delineamento qualitativo. Participaram 9 mães e 7 médicos. Foram realizadas 16 entrevistas semiestruturadas individuais. Os dados foram transcritos e submetidos à análise de conteúdo temática. Constatou-se que, para mães e médicos, é uma experiência complexa e difícil, permeada por sentimentos ambivalentes. Nas mães, predominam a tristeza, medo e angústia. A maioria delas sentiram-se insatisfeitas na maneira como receberam o diagnóstico, isso foi atribuído por elas e pelos médicos à falta de preparo durante a formação profissional. Conclui-se que algumas sugestões podem nortear a comunicação do diagnóstico, no intuito de favorecer a elaboração do mesmo, a saber: respeitar o tempo para a mãe observar e conhecer o bebê antes de receber o diagnóstico, comunicar a mãe com sensibilidade e empatia, preferencialmente na presença do outro genitor e de um psicólogo, procurar dar ênfase aos aspectos positivos da saúde do bebê.

The study aimed to know the experiences of mothers and doctors in relation to the statement of the Down syndrome (DS) diagnosis. This is a exploratory and transversal research, with a qualitative design. 9 mothers and 7 doctors participated. 16 individual semi-structured interviews were carried out. The data were transcribed and submitted to thematic content analysis. It was found that for mothers and doctors, it is a complex and difficult experience, permeated by ambivalent feelings. In mothers, sadness, fear and anguish predominate. Most of them felt dissatisfied in the way as they received the diagnosis, this was attributed by them and the doctors to the lack of preparation during vocational training. It is concluded that, some suggestions can guide the communication of the diagnosis, in order to favor its elaboration, namely: respect the time for the mother to observe and get to know the baby before receiving the diagnosis, communicate it to the mother with sensitivity and empathy, preferably in the presence of the other parent and a psychologist, try to emphasize the positive aspects of the baby's health.

Impacto do diagnóstico de Síndrome de Down na perspectiva materna / Impact of the diagnosis of down syndrome in the maternal perspective / Impacto del diagnóstico del síndrome de down desde la perspectiva materna

Objetivo: compreender as percepções maternas acerca do diagnóstico de Síndrome de Down (SD) de seus filhos quando crianças. Método: estudo exploratório-descritivo com abordagem qualitativa realizado com 9 mães de crianças com SD em um hospital público de nível terciário no município de São Paulo. A coleta dos dados ocorreu por meio de entrevistas individuais e semiestruturadas, guiadas por roteiro de tópicos. Os dados foram analisados por meio da análise temática de conteúdo e à luz dos princípios de ancoragem e objetivação da Teoria das Representações Sociais. Resultados: Os dados foram analisados e emergiram duas categorias principais: 1) as percepções maternas em relação à comunicação do diagnóstico de SD do filho; e 2) as percepções maternas acerca do impacto do diagnóstico de SD do filho, com subcategorias interligadas. Conclusão: constatou-se manejo predominantemente inadequado dos profissionais ao comunicarem o diagnóstico de SD, o que potencializou as reações emocionais de sofrimento, que não se restringiram ao momento da notícia. As reações podem ser amenizadas ou potencializadas com a vivência da maternagem e com interações familiares, sociais e com profissionais de saúde.(AU)

Objective: to understand maternal perceptions about the diagnosis of Down Syndrome (DS) of their children as children. Method: Exploratory-descriptive study with a qualitative approach carried out with 9 mothers of children with DS in a tertiary public hospital in the city of São Paulo. Data collection took place through individual and semi-structured interviews, guided by a script of topics. Data were analyzed using thematic content analysis and considering the principles of anchoring and objectification of the Theory of Social Representations. Results: data were analyzed, and two main categories emerged: 1) maternal perceptions regarding communication of the child's DS diagnosis; and 2) maternal perceptions about the impact of the child's DS diagnosis, with interconnected subcategories. Conclusion: There was predominantly inadequate management by professionals when communicating the diagnosis of DS, which potentiated the emotional reactions of suffering, which were not restricted to the moment of the news. Reactions can be mitigated or enhanced with the experience of motherhood and with family and social interactions and with health professionals.(AU)

Método: estudio exploratorio-descriptivo con enfoque cualitativo, realizado con madres de niños con SD, en un hospital público de tercer nivel, en el municipio de São Paulo. La recolección se realizó a través de entrevistas individuales y semiestructuradas, regidas por un guión de temas. Los datos fueron analizados mediante análisis temático de contenido y a la luz de los principios de anclaje y objetivación de la Teoría de las Representaciones Sociales. Resultados: participaron 9 madres de niños con SD. Los datos se analizaron y surgieron dos categorías principales: 1) Percepciones maternas sobre la comunicación del diagnóstico de SD del hijo, y 2) Percepciones maternas sobre el impacto del diagnóstico de SD del hijo, con subcategorías interconectadas. Conclusión: se constató manejo predominantemente inadecuado de los profesionales en la comunicación del diagnóstico de SD, lo que potenció las reacciones emocionales de sufrimiento, que no se restringieron al momento de la noticia. Las reacciones se pueden mitigar o mejorar con la experiencia de la maternidad, las interacciones con los miembros de la familia, los profesionales de la salud y sociales.(AU)

The influence of siblings with typical development on the burden and quality of life of parents of adolescents with Down syndrome / A influência de irmãos com desenvolvimento típico na sobrecarga e qualidade de vida de pais de adolescentes com síndrome de Down

Objective: The objective of this study was to evaluate the influence of the presence of siblings with normal development on the burden and quality of life of parents of adolescents with Down syndrome. Methods: Cross sectional and correlational study with 25 caregivers divided in two groups: parents who had only children with Down syndrome and parents with other children with normal development. The caregivers were selected from a convenient sample and answered the World Health Organization Quality of Life, Zarit Burden Interview and Brazil's Economic Classification Criteria. Results: It was found that both groups experienced moderate burden and regular quality of life for most families, with no significant difference. Conclusion: It was concluded that the presence of siblings with normal development was not a factor influencing the burden and quality of life of parents of adolescents with Down syndrome.

Objetivo: O objetivo deste estudo foi avaliar a influência da presença de irmãos com desenvolvimento típico na sobrecarga e na qualidade de vida de pais de adolescentes com síndrome de Down. Métodos: Foi realizado um estudo transversal e correlacional, com 25 cuidadores divididos em dois grupos: pais com filhos únicos com síndrome de Down e pais com outros filhos com desenvolvimento típico. Os cuidadores foram selecionados a partir de uma amostragem de conveniência e responderam ao World Health Organization Quality of Life, ao Zarit Burden Interview e ao Critério de Classificação Econômica Brasil. Resultados: Verificou-se que ambos os grupos apresentaram sobrecarga moderada e qualidade de vida regular para a maioria das famílias, não havendo diferença significativa. Conclusão: Conclui-se que a presença de irmãos com desenvolvimento típico não foi fator de influência na sobrecarga e na qualidade de vida de pais de adolescentes com síndrome de Down.

Educação sexual: dificuldades dos pais de jovens com síndrome de down / Sex education: difficulties for parents of young people with down syndrome / Educación sexual: dificultades para los padres de jóvenes con síndrome de down

Com este estudo buscou-se conhecer as dificuldades e barreiras de pais na educação sexual de jovens com Síndrome de Down, a partir de uma pesquisa descritiva e de natureza qualitativa, utilizando-se o conceito das representações sociais como referencial teórico-metodológico. O estudo foi conduzido em uma Organização Não Governamental (ONG), localizada em Recife (PE), após aprovação do Comitê de Ética e Pesquisa, sob parecer consubstanciado 3.558.587. A amostra do estudo envolveu 11 pais de jovens com Síndrome de Down com idades entre 15 e 24 anos. A coleta de dados foi realizada por meio de entrevistas semiestruturadas. A abordagem escolhida para a interpretação desses dados foi a análise de conteúdo proposta por Bardin. Pode-se elencar como principais dificuldades enfrentadas pelos pais ao conversarem com seus filhos sobre sexualidade: a infantilização do jovem com Síndrome de Down, julgando-o incapaz de experienciar tais fenômenos e compreender a orientação que pudesse ser repassada; o medo em ultrapassar etapas e, de repente, "estimular" o filho a viver sua sexualidade de maneira "precoce"; e o fato de os pais também terem recebido pouca ou nenhuma orientação sexual por parte de suas famílias. Diante das narrativas dos pais, é possível perceber que ainda são muitos os mitos, tabus e preconceitos que permeiam a sexualidade dos jovens com Síndrome de Down, demonstrando que os responsáveis estão despreparados para dar as devidas orientações.(AU)

This study sought to know the difficulties and barriers of parents in the sexual education of young people with Down Syndrome, from a descriptive, qualitative study, using the concept of social representations as a theoretical-methodological framework. The study was conducted in a Non-Governmental Organization (NGO), located in Recife (PE) after approval by the Ethics and Research Committee, under substantiated opinion 3,558,587. The study sample involved 11 parents of young people with Down Syndrome aged between 15 and 24 years. The data collection was carried out by using semi-structured interviews. The approach chosen for interpretation of these data was the content analysis proposed by Bardin. The main difficulties faced by parents in talking with their children about sexuality can be listed as: the infantilization of young persons with Down Syndrome, deeming them incapable of experiencing such phenomena and understanding the guidance that could be given; the fear of overshooting the stages and, suddenly, "stimulating" the child to live their sexuality in an "early" way; and the facts of the parents also having received little or no sexual guidance from their families. Given the parents' narratives, it is possible to realize that there are still many myths, taboos, and prejudices that permeate the sexuality of young people with Down Syndrome, demonstrating that parents were unprepared to provide the right guidance.(AU)

Non-Invasive Prenatal Testing:Results in 3733 Cases of Twin Pregnancy and Association With Factors Such as Age / 中国医学科学院学报

Objective To explore the clinical significance of non-invasive prenatal testing(NIPT)for fetal chromosomal abnormalities in the cases of twin pregnancy and its relationship with age and other related factors.Methods A total of 3733 women with twin pregnancy of 12-26+6 weeks who voluntarily underwent NIPT in the Ningbo Women and Children's Hospital from January 2018 to December 2022 were selected.The results of NIPT and amniocentesis were compared and all the participants were followed up.The detection rate of chromosomal abnormalities by NIPT was calculated,and its correlations with age,gestational weeks,chorionicity,and pregnancy type were analyzed.Results Among the 3733 cases,71 cases of fetal chromosome abnormality were indicated by NIPT,including 13 cases of trisomy 21,19 cases of trisomy 18,5 cases of trisomy 13,18 cases of sex chromosome abnormality,and 16 cases of chromosome microdeletion/duplication(excluding 21,18,13,and sex chromosomes),among which 34 cases were true positive and 37 cases were false positive.The overall sensitivity,specificity,and positive predictive value(PPV)of NIPT for chromosomal abnormalities in the cases of twin pregnancy were 100%,98.99%,and 47.89%(34/71),respectively.NIPT showed the sensitivity,specificity,and PPV of 100%,99.78%,and 78.38%(29/37)for trisomy 21,18,and 13,100%,99.56%,and 16.67%(3/18)for sex chromosome abnormalities,and 100%,99.62%,and 12.5%(2/16)for chromosome microdeletion/duplication,respectively.In the age group of ≥40 years,the NIPT for chromosomal abnormalities showed the PPV of 66.67%,the sensitivity of 100%,and the misdiagnosis rate of 30%。However,the NIPT for trisomy 21,18,and 13 showed the PPV of 100%,the misdiagnosis rate of 0,and the sensitivity and specificity of 100%.In terms of grouping based on gestational weeks,the NIPT for chromosomal abnormalities showed the highest PPV(51.28%)in the women with twin pregnancy for 14-17+6 weeks,followed by that(50.00%)in the women with twin pregnancy for 22-26+6 weeks;the NIPT for trisomy 21,18,and 13 showed the highest PPV of 94.74% in the gestation group of 14-17+6 weeks,followed by that(83.33%)in the gestation group of 18-21+6 weeks.The rate of dichorionic diamniotic twins was higher in assisted pregnancies than in natural pregnancies,and NIPT showed the same detection efficiency for dichorionic diamniotic twins and monochorionic diamniotic twins and the same detection efficiency for different pregnancy types.Conclusions NIPT has high accuracy in the diagnosis of twin pregnancy and high sensitivity and high specificity for different ages and gestational weeks,especially for trisomy 21,18,and 13.NIPT is suitable for assisted pregnancy and natural pregnancy,and it is of high value in clinical application.However,extensive application needs a large population-based study.

Retrospective analysis of cell-free fetal DNA prenatal testing of maternal peripheral blood / 中华医学遗传学杂志

OBJECTIVE@#To assess the value of non-invasive prenatal testing (NIPT) for trisomy 21 (T21), trisomy 18 (T18), trisomy 13 (T13), sex chromosome aneuploidies, chromosomal microdeletions and microduplications using cell-free fetal DNA from peripheral blood samples of pregnant women.@*METHODS@#A total of 15 237 pregnant women who had undergone NIPT testing at the Maternity and Child Health Care Hospital of Zaozhuang from February 2015 to December 2021 were enrolled in this study. For those with a high risk by NIPT, amniotic fluid samples were collected for G-banding chromosomal karyotyping analysis and chromosomal microarray analysis to verify the consistency of NIPT with results of prenatal diagnosis. All of the women were followed up by telephone for pregnancy outcomes.@*RESULTS@#Among the 15 237 pregnant women, 266 (1.75%) were detected with a high risk for fetal chromosomal abnormality were detected. Among these, 79 (29.7%) were at a high risk for T21, 26 (9.77%) were at a high risk for T18, 9 (3.38%) were at a high risk for T13, 74 (27.82%) were at a high risk for sex chromosome aneuploidies, 12 (4.51%) were at a high risk for other autosomal aneuploidies, and 66 (24.81%) were at a high risk for chromosomal microdeletions or microduplications. 217 women had accepted invasive prenatal diagnosis and respectively 50, 13, 1, 25, 1 and 18 were confirmed with T21, T18, T13, sex chromosome aneuploidies, autosomal aneuploidies and microdeletions/microduplications, and the positive predictive values were 75.76%, 68.42%, 11.11%, 40.32%, 10% and 35.29%, respectively. For 13 042 women (85.59%), the outcome of pregnancy were successfully followed up. During the follow-up, one false negative case of T21 was discovered. No false positive cases for T13 and T18 were found.@*CONCLUSION@#NIPT has a sound performance for screening T13, T18 and T21, and is also valuable for screening other autosomal aneuploidies, sex chromosome aneuploidies and chromosomal microdeletions/microduplications.

Prenatal diagnosis of two fetuses with Xp22.31 microdeletion syndrome indicated by non-invasive prenatal testing / 中华医学遗传学杂志

OBJECTIVE@#To assess the value of non-invasive prenatal testing (NIPT) for detecting fetal chromosomal microdeletion/microduplication syndromes by carrying out prenatal diagnoses for two fetuses with Xp22.31 microdeletion indicated by NIPT.@*METHODS@#Two pregnant women suspected for fetal Xp22.31 microdeletion syndrome who presented at Zaozhuang Maternal and Child Health Care Hospital on December 5, 2017 and October 15, 2020 were selected as the study subjects. Clinical data of the two women were collected, and peripheral venous blood samples were collected for NIPT testing. Amniotic fluid samples were taken for G-banding chromosomal karyotyping analysis and copy number variation sequencing (CNV-seq) for fetus 1, while G-banding chromosomal karyotyping and single nucleotide polymorphism microarray analysis (SNP array) were carried out for fetus 2. Peripheral venous blood samples of couple 1 were collected for CNV-seq to verify the origin of copy number variation .@*RESULTS@#NIPT indicated that fetus 1 had harbored a 1.3 Mb deletion in the Xp22.31 region, while G-banding chromosomal karyotyping had found no abnormality. CNV-seq analysis verified the fetus to be seg[GRCh37]del(X)(p22.31)chrX:g.6800001_7940000del, with a 1.14 Mb deletion at Xp22.31, which was derived from its mother. NIPT indicated that fetus 2 had harbored a 1.54 Mb deletion in the Xp22.31 region, while G-banding chromosomal karyotyping had found no abnormality. SNP array analysis indicated arr[GRCh37]Xp22.31(6458940_8003247)×0, with a 1.54 Mb deletion in Xp22.31 region.@*CONCLUSION@#NIPT not only has a good performance for detecting fetal trisomies 21, 18 and 13, but also has the potential for detecting chromosomal microdeletion/microduplications. For high risk fetuses indicated by NIPT, prenatal diagnosis needs to be carry out to verify the chromosomal abnormalities.

Gingivitis in children with down syndrome: Review of local and systemic factors

Objective@#To describe various local and systemic factors as the cause of gingivitis and to find out the main etiological factors of gingivitis in children with DS.@*Methods@#We searched PubMed and Google Scholar for Indonesian and English references either in the form of textbook, research results, reviews, and internet articles on the topic. We screened and selected the relevant articles for inclusion into the review. @*Results@#In children with DS, apart from poor oral hygiene, the increasing incidence of gingivitis is caused by changes in other local factors related to systemic factors, such as oral dysfunction, dental and gingival abnormalities, changes in the oral microbial profile, and salivary characteristics. Furthermore, systemic immunodeficiency, changes in inflammatory mediators and proteolytic enzymes, and intellectual subnormality are considered as systemic factors.@*Conclusion@#There is no main etiological factor of gingivitis in children with DS since various local and systemic factors are interrelated with each other causing gingivitis. The severity of gingivitis in children with DS presumably were caused by the systemic factors. Furthermore, good oral hygiene habits and the dentist's intervention in periodontal health can significantly reduce gingivitis in DS patients.

Analysis for trends in disease burden of congenital birth defects among children under 5 years old in China / 中南大学学报(医学版)

OBJECTIVES@#Congenital birth defects are the main source of disease burden among children under 5 years old in China. This study aims to compare the trends in disease burden of different congenital birth defects among Chinese children under 5 years old from 1990 to 2019, and to provide a scientific basis for strengthening the comprehensive prevention and control of birth defects.@*METHODS@#Based on data from the Global Burden Disease (GBD) in 2019, the incidence mortality rate, and disability-adjusted life years (DALYs) rate of congenital birth defects among Chinese children under 5 years old from 1990 to 2019 were selected as evaluation indicators. The Joinpoint regression model was used to analyze the trends in disease burden of different types with congenital birth defects over three decades. The study also compared the differences in disease burden of congenital birth defects among children under 5 years old by gender.@*RESULTS@#Compared to 1990, the DALYs rates of congenital heart anomalies (1 931.91/100 000), digestive congenital anomalies (364.63/100 000), neural tube defects (277.20/100 000), congenital musculoskeletal and limb anomalies (133.33/100 000), and Down syndrome (128.22/100 000) in children under 5 years old in China in 2019 were decreased 70.78%, 71.61%, 86.21%, 36.84% and 73.65%, respectively. From 1990 to 2019, the mortality rates and DALYs rates of different congenital birth defects showed an overall downward trend, but the incidence of digestive congenital anomalies and Down syndrome showed an upward trend after 2005 and 2001, respectively. Except for congenital musculoskeletal and limb anomalies, incidence of the remaining categories of birth defects were higher in boys than that in girls.@*CONCLUSIONS@#The disease burden of congenital birth defects in children under 5 years old in China is decreased substantially from 1990 to 2019, but the burden of congenital heart anomalies is still serious and the incidence of some birth defect diseases is on the rise, and it is still crucial to strengthen the prevention and treatment for birth defects in children and propose targeted measures according to their gender characteristics.
