Prevalence at Birth of Cleft Lip With or Without Cleft Palate: Data From the International Perinatal Database of Typical Oral Clefts (IPDTOC).
As part of a collaborative project on the epidemiology of craniofacial anomalies, funded by the National Institutes for Dental and Craniofacial Research and channeled through the Human Genetics Programme of the World Health Organization, the International Perinatal Database of Typical Orofacial Clefts (IPDTOC) was established in 2003. IPDTOC is collecting case-by-case information on cleft lip with or without cleft palate and on cleft palate alone from birth defects registries contributing to at least one of three collaborative organizations: European Surveillance Systems of Congenital Anomalies (EUROCAT) in Europe, National Birth Defects Prevention Network (NBDPN) in the United States, and International Clearinghouse for Birth Defects Surveillance and Research (ICBDSR) worldwide. Analysis of the collected information is performed centrally at the ICBDSR Centre in Rome, Italy, to maximize the comparability of results. The present paper, the first of a series, reports data on the prevalence of cleft lip with or without cleft palate from 54 registries in 30 countries over at least 1 complete year during the period 2000 to 2005. Thus, the denominator comprises more than 7.5 million births. A total of 7704 cases of cleft lip with or without cleft palate (7141 livebirths, 237 stillbirths, 301 terminations of pregnancy, and 25 with pregnancy outcome unknown) were available. The overall prevalence of cleft lip with or without cleft palate was 9.92 per 10,000. The prevalence of cleft lip was 3.28 per 10,000, and that of cleft lip and palate was 6.64 per 10,000. There were 5918 cases (76.8%) that were isolated, 1224 (15.9%) had malformations in other systems, and 562 (7.3%) occurred as part of recognized syndromes. Cases with greater dysmorphological severity of cleft lip with or without cleft palate were more likely to include malformations of other systems
Atrioventricular septal defects among infants in Europe: a population-based study of prevalence, associated anomalies, and survival
OBJECTIVE: To describe the epidemiology of chromosomal and non-chromosomal cases of atrioventricular septal defects in Europe. METHODS: Data were obtained from EUROCAT, a European network of population-based registries collecting data on congenital anomalies. Data from 13 registries for the period 2000-2008 were included. RESULTS: There was a total of 993 cases of atrioventricular septal defects, with a total prevalence of 5.3 per 10,000 births (95% confidence interval 4.1 to 6.5). Of the total cases, 250 were isolated cardiac lesions, 583 were chromosomal cases, 79 had multiple anomalies, 58 had heterotaxia sequence, and 23 had a monogenic syndrome. The total prevalence of chromosomal cases was 3.1 per 10,000 (95% confidence interval 1.9 to 4.3), with a large variation between registers. Of the 993 cases, 639 cases were live births, 45 were stillbirths, and 309 were terminations of pregnancy owing to foetal anomaly. Among the groups, additional associated cardiac anomalies were most frequent in heterotaxia cases (38%) and least frequent in chromosomal cases (8%). Coarctation of the aorta was the most common associated cardiac defect. The 1-week survival rate for live births was 94%. CONCLUSION: Of all cases, three-quarters were associated with other anomalies, both chromosomal and non-chromosomal. For infants with atrioventricular septal defects and no chromosomal anomalies, cardiac defects were often more complex compared with infants with atrioventricular septal defects and a chromosomal anomaly. Clinical outcomes for atrioventricular septal defects varied between regions. The proportion of termination of pregnancy for foetal anomaly was higher for cases with multiple anomalies, chromosomal anomalies, and heterotaxia sequence
Der Anteil pränatal erfasster Fälle von ausgewählten Fehlbildungen in der EUROCAT-Studie. Ergebnisse im Kanton Zürich von 1988 bis 1997
In the context of the EUROCAT study, data on selected congenital malformations and chromosome aberrations were collected from the Canton of Zurich (1988-1997). It was found that the major proportion of severe and early malformations, such as anencephalus and holoprosencephaly, were detected prenatally; for oral clefts and meningomyeloceles this was not the case, at any rate in regard to isolated (non-syndromic) malformations. However, if these defects occur in combination with a chromosome aberration, the likelihood of such a case being registered is higher. For the same reason, i.e. due to abnormal ultrasound findings and intrauterine growth retardation, trisomies 13 and 18 were more often detected prenatally than trisomy 21
Quantitative sequence analysis of FBN1 premature termination codons provides evidence for incomplete NMD in leukocytes
We improved, evaluated, and used Sanger sequencing for quantification of single nucleotide polymorphism (SNP) variants in transcripts and gDNA samples. This improved assay resulted in highly reproducible relative allele frequencies (e.g., for a heterozygous gDNA 50.0+/-1.4%, and for a missense mutation-bearing transcript 46.9+/-3.7%) with a lower detection limit of 3-9%. It provided excellent accuracy and linear correlation between expected and observed relative allele frequencies. This sequencing assay, which can also be used for the quantification of copy number variations (CNVs), methylations, mosaicisms, and DNA pools, enabled us to analyze transcripts of the FBN1 gene in fibroblasts and blood samples of patients with suspected Marfan syndrome not only qualitatively but also quantitatively. We report a total of 18 novel and 19 known FBN1 sequence variants leading to a premature termination codon (PTC), 26 of which we analyzed by quantitative sequencing both at gDNA and cDNA levels. The relative amounts of PTC-containing FBN1 transcripts in fresh and PAXgene-stabilized blood samples were significantly higher (33.0+/-3.9% to 80.0+/-7.2%) than those detected in affected fibroblasts with inhibition of nonsense-mediated mRNA decay (NMD) (11.0+/-2.1% to 25.0+/-1.8%), whereas in fibroblasts without NMD inhibition no mutant alleles could be detected. These results provide evidence for incomplete NMD in leukocytes and have particular importance for RNA-based analyses not only in FBN1 but also in other genes
Analisando o programa de apoio as incubadoras de cooperativas populares no contexto do debate sobre as políticas sociais no Brasil
This dissertation aims to analyse the National Program of Incubators of Popular Cooperatives (Proninc, in the portuguese abbreviation) since the debates, in the general and in Brazil, about social policies. For that, we carry out a course seeking to place the patterns of State intervention in the social field and how they vary in the history. The contextualization in the brazilian case is fundamental to recognize the specific chateristics that these initiatives from the public power acquired in that country. Being the program somehow a product of the organization of the political purpose from the social movement of ‘solidarity economy’, it has been necessary also to approach the insertion of the theme in the brazilian State, for better comprehension of the studied object. The author has part of the staff that did the ‘Proninc Evaluation 2017’ what has allowed an experience in seminars and in the field that has contributed in the process of making of this dissertation. In that way, we used the methodologies of sistematization of experiences described by Jara Holliday (2012) and also tried to get closer of the ‘grounded theory’ proposal developed by Flick (2004).Na presente dissertação pretendemos analisar o Programa Nacional de Incubadoras de Cooperativas Populares (PRONINC) a partir dos debates, no geral e no Brasil, sobre as políticas sociais. Para tanto, realizamos um percurso buscando situar os padrões de intervenção estatal no campo social e como elas variariam na história. A contextualização no caso brasileiro é fundamental para reconhecer as características específicas que essas iniciativas do poder público adquiriram aqui. Sendo o programa fruto da organização da proposta política do movimento de economia solidária, se fez necessário também abordar o tema e suas especificidades, bem como a inserção do tema no aparelho estatal brasileiro, para melhor compreensão do objeto estudado. O autor fez parte da equipe que realizou a Avaliação Proninc 2017 o que permitiu uma vivência em seminários e em campo que contribuiu na consecução dessa dissertação. Desse modo, utilizamos as metodologias de sistematização de experiências descrita por Jara Holliday (2012) e também tentamos nos aproximar da proposta de grounded theory desenvolvida por Flick (2004)
Prenatal diagnosis and epidemiology of multicystic kidney dysplasia in Europe
ObjectivesThe aim of this study is to describe the prenatal diagnosis and epidemiology of multicystic kidney dysplasia (MCKD). MethodsThe study is based on routinely collected data from a European database of major congenital anomalies including 13 registries with cases born in 1997-2006 and covering 1458552 births. ResultsThere were 601 MCKD cases giving an overall prevalence of 4.12 per 10000 births with regional variation. In live births, 87% of cases had an isolated renal anomaly and 13% had associated major nonrenal anomalies (chromosomal, syndrome or other major anomalies). For the cases with isolated renal anomalies, 51/386 (11%) and 7/386 (2%) choose to terminate the pregnancy or resulted in an intrauterine fetal death, respectively. The prenatal detection rate was 88% in both unilateral and bilateral cases. Birth outcome differed with 92% of unilateral MCKD cases being liveborn compared with 33% of bilateral MCKD cases. For unilateral MCKD cases, 84% had an isolated renal anomaly compared with 51% of bilateral MCKD cases (p ConclusionsCases with unilateral MCKD are mainly liveborn, and only 16% have associated major malformations or a syndrome. Cases with bilateral MCKD are often associated with nonrenal major congenital anomalies or part of a syndrome, and only one third of bilateral MCKD cases in this study were liveborn. Prenatal detection rate of MCKD was high for both unilateral and bilateral cases. (c) 2014 John Wiley & Sons, Ltd
