Download or read book Reducing Birth Defects written by Institute of Medicine and published by National Academies Press. This book was released on 2003-10-27 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year more than 4 million children are born with birth defects. This book highlights the unprecedented opportunity to improve the lives of children and families in developing countries by preventing some birth defects and reducing the consequences of others. A number of developing countries with more comprehensive health care systems are making significant progress in the prevention and care of birth defects. In many other developing countries, however, policymakers have limited knowledge of the negative impact of birth defects and are largely unaware of the affordable and effective interventions available to reduce the impact of certain conditions. Reducing Birth Defects: Meeting the Challenge in the Developing World includes descriptions of successful programs and presents a plan of action to address critical gaps in the understanding, prevention, and treatment of birth defects in developing countries. This study also recommends capacity building, priority research, and institutional and global efforts to reduce the incidence and impact of birth defects in developing countries.

Download or read book Technologies for Prenatal Diagnosis and Assessment of Genetic Disorders written by Fan Jin and published by Frontiers Media SA. This book was released on 2020-06-22 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birth defects are one of the major public health concerns in the world, as they cause approximately 20% of infant deaths. Genetic disorders, including chromosome abnormalities and single gene disorders, are the most common causes of birth defects for which there is no efficient treatment. Prenatal genetic screening and diagnosis allow early identification of affected conceptuses and facilitates reproduction planning or counseling. Molecular technologies have developed rapidly in recent years and have been widely used in screening and diagnosis of genetic disorders at all stages of prenatal development (e.g. pre-implantation, embryonic and fetal). However, their performance still needs to be validated and assessed as the balance between their advantages and disadvantages need to be discussed. With the ability to detect copy number variations (CNVs), polyploidy, uniparental disomy and maternal cell contamination, SNP-based chromosomal microarray analysis (CMA) is showing the unique importance in diagnosing chromosomal abnormalities. The interpretation of CNVs remains a challenge; however, ultrasound and biochemical screening improve the diagnosis of fetal chromosomal abnormalities. Whole exome sequencing (WES) and whole genome sequencing (WGS) play increasingly significant roles in prenatal and carrier screening for genetic disorders. NGS-based non-invasive prenatal screening (NIPS) is now widely used for detecting common autosomal aneuploidies and has shown the potential of detecting microdeletions and microduplications. However, further investigations of the sensitivity and accuracy are required and large-scale data is necessary to evaluate the performance and clinical applications of current and new methods. Recently, reports of application of newer technologies in prenatal setting became available. Examples include third generation sequencing (reading the nucleotide sequences at the single molecule level), digital PCR (used for direct quantification of DNA) and cell-based NIPT. In the followed listed papers, the authors showed their successful experiences in identifying novel mutation, detecting low-level mosaicism or de novo mutations limited in germline cells, investigating the association of the CNVs with specific phenotypic alterations by using WES, CMA, digital PCR and some other new-developed molecular techniques. More interesting, the authors also presented a report about the evaluation of diagnostic yield in fetal WES, which suggested a new tendency to apply WES or WGS directly for prenatal diagnosis. We believed that the efficiency of scanning causative mutations and prenatal or preimplantion genetic diagnosis for genetic disorders will further improved based on the technologies of whole genomic sequencing with further improved output and resolution. New techniques, such as quick-WES for the newborn in intensive care unit, direct-WGS for prenatal diagnosis and non-invasive test for fetal monogenic disorders, will become available in the near future.
Download or read book Genetic Disorders Syndromology and Prenatal Diagnosis written by T.V.N. Persaud and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birth defects have assumed an importance even greater now than in the past because infant mortality rates attributed to congenital anomalies have declined far less than those for other causes of death, such as infectious and nutritional diseases. As many as 50 % of all pregnancies terminate as miscarriages, and in the majority of cases this is the result of faulty intrauterine development. Major congenital malformations are present in at least 2 % of all liveborn infants, and 22 % of all stillbirths and infant deaths are associated with severe congenital anomalies. Not surprisingly, there has been a great proliferation of research into the problems of developmental abnormalities over the past few decades. This series, Advances in the Study of Birth Defects, was conceived in order to provide a comprehensive focal source of up-to-date information for physi cians concerned with the health of the unborn child and for research workers in the fields of fetal medicine and birth defects. The first four volumes featured recent experimental work on selected areas of high priority and intensive investigation, including mechanisms of teratogenesis, teratological evaluation, molecular and cellular aspects of abnormal development, and neural and behavioural teratology. It seems logical and timely that the clinical aspects should now be presented. Accordingly, leading experts were invited to review a broad range of common problems from the standpoint of embryology, aetiology, clinical manifestations, diagnosis and management. This volume deals with genetic disorders and prenatal diagnosis.

Download or read book Gardner and Sutherland s Chromosome Abnormalities and Genetic Counseling written by R.J. McKinlay Gardner and published by Oxford University Press. This book was released on 2018-02-06 with total page 729 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even as classic cytogenetics has given way to molecular karyotyping, and as new deletion and duplication syndromes are identified almost every day, the fundamental role of the genetics clinic remains mostly unchanged. Genetic counselors and medical geneticists explain the "unexplainable," helping families understand why abnormalities occur and whether they're likely to occur again. Chromosome Abnormalities and Genetic Counseling is the genetics professional's definitive guide to navigating both chromosome disorders and the clinical questions of the families they impact. Combining a primer on these disorders with the most current approach to their best clinical approaches, this classic text is more than just a reference; it is a guide to how to think about these disorders, even as our technical understanding of them continues to evolve. Completely updated and still infused with the warmth and voice that have made it essential reading for professionals across medical genetics, this edition of Chromosome Abnormalities and Genetic Counseling represents a leap forward in clinical understanding and communication. It is, as ever, essential reading for the field.
Download or read book Genetic Disorders and the Fetus written by Aubrey Milunsky and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: Technological advances continue to expand the number of genetic disorders that can be diagnosed in utero. Utilization of this new technology has de manded special expertise available in relatively few academic centers. As these new applications have become more widespread so have the realities of the medicolegal implications. Notwithstanding the laboratory challenges, most legal action, at least in the United States, has arisen from the physician's failure to inform a patient about the risks of a genetic disorder or the oppor tunities presented by prenatal diagnosis. Hence an extensive thorough reex amination of the subject seems appropriate and timely. The steady escalation in the number of prenatal genetic studies now being done in the western world makes it imperative for the physician to have a thorough comprehension of the subject in its entirety. I am, therefore, fortu nate in having colleagues who as acknowledged experts have shared their knowledge and experience in order to make this volume a major critical repository of facts and guidance about prenatal genetic diagnosis. The subject matter ranges from a consideration of required genetic counseling through the intricacies of establishing prenatal diagnoses. Special attention is focused on new advances using ultrasound, a-fetoprotein, fetoscopy, and first trimester diagnosis. Both ethical and legal implications are discussed in detail, as is the development of public policy.
Download or read book Pathology of the Human Embryo and Previable Fetus written by Dagmar K. Kalousek and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed primarily for anatomic pathologists to facilitate their task of accurately diagnosing embryos and fetuses. A detailed examination of the products of spontaneous and induced abortions is necessary for accurate genetic counseling and for establishing the risk for specific abnormalities or another spontaneous pregnancy loss in the future. The growing interest in the defects of early development reflects the profound change in general life-style. In the past, spontaneous abortions were considered a common, usually sporadic event in a patient's reproductive history. Only reassurance and encour agement were given to the patient and scant attention was paid to the detailed pathology of the abortus. Nowadays, however, as a result of reliable methods of contraception and of the availability of reliable prenatal diagnosis for chromosome abnormalities more frequent in advanced maternal age, significant numbers of parents plan to have pregnan cies later in their reproductive life. Consequently, in a case of spontaneous abortion, the question of "cause" and of "future risk" of recurrence of abortion or an abnormal infant is particularly important. In the era of more elaborate and accurate prenatal diagnostic tests, the pathologist examining products of conception has a primary responsibility to detect, in both spontaneous and induced abortions, any developmental abnormality that would indicate an increased risk of multifactorial, chromosomal, and single gene disorders in a subsequent child.
Download or read book Congenital Anomalies written by Stefania Tudorache and published by BoD – Books on Demand. This book was released on 2018-05-02 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, nobody can imagine practicing obstetrics without using obstetrical ultrasound. Working in the prenatal diagnosis field requires dedication, patience, skills, experience, caution, and empathy. The concept of this book was guided by the desire to provide some help to the ultrasound operators. On a daily basis, they are confronted with the challenging task of ruling out or suspecting/confirming the diagnosis of fetal anomalies, either structural or chromosomal. The chapters of this book contain objective and exhaustive updated reviews of the pertinent literature, so that the reader would have a wide reference basis on each subject. Yet, many authors scan the fetus themselves or are directly involved with managing pregnancies with structural malformations or chromosomal anomalies. They kindly shared their personal experience and lessons learned over the years. This book is beneficial for all the professionals working in the prenatal diagnosis.
Download or read book Scientific Frontiers in Developmental Toxicology and Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 2000-12-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Download or read book Conception to Birth written by Jennie Kline and published by Oxford University Press, USA. This book was released on 1989 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first systematic and in-depth epidemiological treatment of prenatal development, from fertilization to birth. It lays the groundwork for causal thinking about prenatal development by discussing criteria for evaluating observed associations between teratogens and developmental outcomes. The authors map development epidemiologically, dealing with the probabilities of conception and early loss, the relation between miscarriage and chromosome abnormalities, and the questions of recurrence and environmental influences on pregnancy loss. The discussion of fetal growth distinguishes between preterm delivery, retarded growth, and immaturity. Indices for measuring growth are analyzed. The predominant maternal and environmental influences on prenatal growth and birth weight are reconciled with the genetic contribution to postnatal growth. Finally, the book examines the major issues of maternal age and parity, and addresses the public health challenge of monitoring and surveillance. As a unique synthesis of epidemiological knowledge, this volume perfectly complements the more well-known work being done in prenatal development in the fields of biology, physiology, and genetics.
Download or read book Exploring the Biological Contributions to Human Health written by Institute of Medicine and published by National Academies Press. This book was released on 2001-07-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
Download or read book Chromosome Abnormalities and Genetic Counseling written by R. J. McKinlay Gardner and published by Oxford University Press. This book was released on 2003-08-28 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromosomal abnormalities can cause disability in children, and reproductive difficulty in parents. Many parents and couples seek genetic counseling in order to learn why they, or a relative, may have had a child with a particular collection of medical problems and/or intellectual disability. There may have been a history of multiple miscarriage, or infertility. They may want to know the outlook for a pregnancy, and what the risks might be. These and other questions concerning chromosome abnormalities are addressed in this standard text, which will be of interest to genetic counselors, medical geneticists, pediatricians and obstetricians, infertility specialists, and laboratory cytogeneticists. This third edition has been thorougly updated, and is richly illustrated and fully referenced. New chapters have been written on preimplantation diagnosis and on reproductive risks due to environmental agents. The practical applications of recent advances in molecular cytogentics are noted. The book will give counselors the information that will enable them to help concerned parents accommodate to their particular "chromosomal situation", and to determine what may be, for them, the best course of action.
