Carmen Mesas Burgos Vikas S. Gupta Peter Conner Björn Frenckner Kevin P. Lally Ashley H. Ebanks Matthew T. Harting For The Congenital Diaphragmatic Hernia Study Group 《黑龙江环境通报》2023,43(10):1265-1273
Background
The aim of this study was to describe the incidence of Congenital Diaphragmatic Hernia, CDH, associated with known or clinically suspected syndromes, and the postnatal outcomes from a large database for CDH.Methods
Data from the multicenter, multinational database on infants with CDH (Congenital Diaphragmatic Hernia Study Group Registry) born from 1996 to 2020 were analyzed. Patients with known or suspected syndromes were grouped and outcome data were analyzed and compared to those without syndromic features.Results
A total of 12,553 patients were entered in the registry during the study period, and 421 had reported known syndromes, representing 3.4% of all CDH cases in the registry. A total of 50 different associated syndromes were reported. In addition to those with clinically suspected genetic conditions, a total rate of genetic syndromes with CDH was 8.2%. The overall survival to discharge for syndromic CDH was 34% and for non-syndromic CDH was 76.7%. The most common were syndromes Fryns syndrome (19.7% of all syndromes, 17% survival), trisomy 18 or Edward syndrome (17.5%, 9% survival), trisomy 21 or Down syndrome (9%, 47% survival), trisomy 13 or Patau syndrome (6.7%, 14% survival), Cornelia de Lange syndrome (6.4% of all syndromes, 22% survival) and Pallister-Killian syndrome (5.5% of all syndromes, 39.1% survival). In addition, 379 cases had reported chromosomal anomalies and 233 cases had clinically suspected syndromes, based on two more dysmorphic features or malformations in addition to CDH, but without molecular diagnosis. The syndromic CDH group had lower birth weight and gestational age at birth and increased incidence of bilateral CDH (2.9%) and rates of non-repair (53%). The length of hospital stay was longer, and larger number of patients needed O2 at 30 days. Extracorporeal life support was used only in 15% of the cases. Those who underwent surgical repair had survival to discharge rates of 73%.Conclusion
Syndromic CDH is rare and only 3.4% of the reported cases of CDH have a known syndrome or association, but, if including patients with two dysmorphic features malformations, in addition to CDH, altogether as many as 8.2% have a diagnosed or suspected genetic condition. These children have with lower survival rates. Given higher rates of non-repair and decreased extracorporeal life support use, along with a high early mortality, decision-making regarding goals of care clearly influences outcomes. Survival varies depending on the genetic cause. Early genetic diagnosis is important and may influence the decision-making. 相似文献53.

藻类生物技术在水环境保护中的应用前景探讨 总被引:2,自引:0,他引:2
简要综述了藻类生物技术在水污染生态毒理学和污水生物净化方面的研究成果及应用实例,同时对其研究前景进行了探讨。应用藻类生物检测技术对重金属、农药、有机污染物、有毒有害废弃物等的毒性评价结果证明,一些二价重金属阳离子对藻类的毒性顺序大致为Hg~(2+),Cd~(2+),Cu~(2+),Ni~(2+)和 Zn~(2+);酚类、酯类和芳烃类有机污染物对藻类生长的抑制作用十分显著;农药对藻类的毒害作用主要通过破坏藻类生物膜的结构和功能而抑制藻类的光合作用、呼吸作用和固氮作用。有关藻类污水处理的研究资料显示,阳光的强弱,污水在系统内的停留时间,藻类生物量的多寡是确保藻类污水处理效果的关键。 相似文献

Ellen Hollands Steffensen Anne Skakkebæk Kasper Gadsbøll Olav Bjørn Petersen Thomas Westover Heather Strange The NIPT-SCA-map Study Group Ida Vogel 《黑龙江环境通报》2023,43(2):144-155
Objective
To examine the extent to which sex chromosomes are included in current noninvasive prenatal testing (NIPT) and the reporting practices with respect to fetal chromosomal sex and sex chromosome aberrations (SCAs), in addition to an update on the general implementation of NIPT.Method
A questionnaire addressing the research objectives was distributed by email to fetal medicine and clinical genetics experts in Asia, Australia, Europe and the USA.Results
Guidelines on NIPT are available in the majority of the included countries. Not all existing guidelines address reporting of fetal chromosomal sex and SCAs. In most settings, NIPT frequently includes sex chromosomes (five Australian states, China, Hong Kong, Israel, Singapore, Thailand, USA and 23 of 31 European countries). This occurs most often by default or when parents wish to know fetal sex. In most settings, a potential SCA is reported by stating the risk hereof as “low” or “high” and/or by naming the SCA. Less than 50% of all pregnant women receive NIPT according to respondents from three Australian states, China, Israel, Singapore, Thailand and 24 of 31 European countries. However, this percentage, the genomic coverage of NIPT and its application as primary or secondary screening vary by setting.Conclusion
In most of the studied countries/states, NIPT commonly includes sex chromosomes. The reporting practices concerning fetal chromosomal sex and SCAs are diverse and most commonly not addressed by guidelines. In general, NIPT is variably implemented across countries/states. 相似文献57.
