    Birth defects are an urgent global health priority. They affect millions of births worldwide. But their prevalence and impact are largely under-ascertained, particularly in middle- and low-income countries. Fortunately, a large proportion of birth defects can be prevented. This review examines the global prevalence and primary prevention methods for major preventable birth defects: congenital rubella syndrome, folic acid-preventable spina bifida and anencephaly, fetal alcohol syndrome, Down syndrome, rhesus hemolytic disease of the fetus and the newborn; and those associated with maternal diabetes, and maternal exposure to valproic acid or iodine deficiency during pregnancy. Challenges to prevention efforts are reviewed. The aim of this review is to bring to the forefront the urgency of birth defects prevention, surveillance, and prenatal screening and counseling; and to help public health practitioners develop population-based birth defects surveillance and prevention programs, and policy-makers to develop and implement science-based public health policies.

    2014-07-01

    Full Text Available Birth defects refer to a group of diverse congenital conditions, which are responsible for stillbirths, neonatal deaths, chronic medical conditions and disability. Due to their low prevalence and high mortality, birth defects are not considered to be a significant health problem in India. Various data however identify that India may harbour a significant burden of birth defects, and that these conditions may be responsible for a considerable proportion of neonatal deaths in India. Although it is widely assumed that survival of patients with birth defects is low, data suggests that in 2002, there were nearly six million Indians living with impairments arising at birth. These data urge the need for implementation of a national birth defects programme in India, with a strong component of prevention. The need for significant research investments to understand the epidemiology and public health impact of birth defects in India is identified. Translation research, transcending the disciplines of medicine, public health and genetics is required to develop a low cost birth defects service as a component of the existing maternal and child health programme.

    In order to translate research findings into effective prevention strategies, it is important to understand people's beliefs about the causes of poor health outcomes. However, with the exception of knowledge and beliefs about folic acid supplementation, little is known regarding women's causal attributions women regarding birth defects. We employed Attribution Theory constructs to analyze open-text interview responses from 2,672 control mothers in the National Birth Defects Prevention Study who gave birth in 1997-2005. Common themes included use of alcohol, tobacco, illicit drugs, and medications during pregnancy. Stress and emotional upset were also suggested as possible causes of birth defects. Genetic- and heredity-related responses were more likely to be mentioned by Asian/Pacific Islander women compared to non-Hispanic Whites. Hispanic women were less likely to suggest several specific possible teratogens, such as paint, pesticides, or other chemicals, but were more likely to suggest events occurring during childbirth. Differences also emerged among ethnic groups for theoretical constructs, although most responses were categorized as controllable, changeable over time, and with an internal locus of causality.

    Full Text Available Periconceptional use of folic acid alone or in multivitamin supplements is effective for the primary prevention of neural-tube defects. The Hungarian randomized and two-cohort controlled trials showed that periconceptional multivitamin supplementation can reduce the occurrence of some other structural birth defects, i.e. congenital abnormalities. These findings were supported by many, but not all observational studies. Recently there have been two main debated questions. The first one is whether the use of folic acid alone or folic acid-containing multivitamins is better. The second one is connected with the dilemma of whether high dose of folic acid (e.g. 5 mg might be better than a daily multivitamin with 0.4 – 0.8 mg of folic acid. Comparison of the pooled data of two Hungarian trials using a multivitamin containing 0.8 mg folic acid and the data of the Hungarian Case-Control Surveillance of Congenital Abnormalities using high dose of folic acid seemed to be appropriate to answer these questions. Multivitamins containing 0.4 – 0.8 mg of folic acid were more effective for the reduction of neural-tube defects than high dose of folic acid. Both multivitamins and folic acid can prevent some part of congenital cardiovascular malformations. Only multivitamins were able to reduce the prevalence at birth of obstructive defects of urinary tract, limb deficiencies and congenital pyloric stenosis. However, folic acid was effective in preventing some part of rectal/anal stenosis/atresia, and high dose of folic acid had effect in preventing some orofacial clefts. The findings are consistent that periconceptional multivitamin and folic acid supplementation reduce the overall occurrence of congenital abnormalities in addition to the demonstrated effect on neural-tube defects.

    Birth defects (BDs) are an important public health problem, due to their overall incidence, occurring in 2-3% of live births in European Union. Neural tube defects (NTDs) are among major NTDs, due to their severity and relatively high incidence; in the meanwhile NTDs are also the most effectively preventable BDs to date. In particular, an adequate folic acid (FA) intake reduces both the occurrence and the recurrence of NTDs; FA is the synthetic form of folates, naturally occurring vitamins in a number of foods, especially vegetables. The daily intake of 0.4 mg of FA should be recommended to all women of childbearing age who plan to become pregnant. The Italian Network for Primary Prevention of BDs through FA Promotion has achieved a significant improvement in FA awareness and use in the periconceptional period. Nevertheless, primary prevention of BDs needs to make further progress; the Italian National Centre for Rare Diseases participates in european sureveillance of congenital anomalies (EUROCAT) Joint Action as coordinator of activities on the effectiveness of BDs prevention. Mandatory food fortification with FA has not been introduced in any European country. The health benefits of FA in reducing the risk of NTDs are undisputed; however mechanistic and animal studies suggest a relationship between high FA intakes and increased cancer promotion, while human studies are still inconsistent and inconclusive. A Working Group organized by the European Food Safety Authority pointed out significant uncertainties about fortification safety and the need for more studies; currently, FA intake from fortified foods and supplements should not exceed 1 mg/day in adults. In conclusion, based on up-to-date scientific evidence, the Italian Network strategy pivots on periconceptional supplementation integrated with promotion of healthy eating habits, support to health education, enhancing the role of women in managing life choices about their health and pregnancy and increasing

    Incidence of anencephaly in the State of Zulia, and specifically in the Eastern Coast of Lake Maracaibo, an oil exploitation area, has been declared high since the beginning of the 80's, coincident with the generalized use of ultrasound as a diagnostic tool for fetal evaluation. Through the Birth Defects Preventive Program, established at the Hospital Chiquinquira in Maracaibo, we have developed a fourfold strategy for the study of birth defects: i) analysis of more than 32,332 ultrasound evaluations within the Ultrasound Service, between 1993 and 1996, ii) a case-control malformation registry beginning in 1995, iii) a study of malformed stillbirths at the Pathology Service, observed after 4232 deliveries within this hospital, and iv) a registry of over 638 mothers with high risk pregnancy for fetal defects detected at the prenatal clinic and carried out at the Perinatal Medical Genetics Service. As a reference population we study 345 medical histories obtained from the Medical Genetics and Prenatal Diagnostic Service at Hospital Coromoto, and oil companies related medical facility. This approach has led us to conclude that the incidence of anencephaly in the State of Zulia is 0.75/1000, significantly similar to that expected for most populations

Samples were obtained from 737 NTD case-parent triads included in the National Birth Defects Prevention Study during 1999-2007. Log-linear models were used to evaluate maternal and offspring genetic effects. After application of the false discovery rate, there were 5 significant maternal genetic effects. The less common alleles at the 4 FTO single nucleotide polymorphisms showed a reduction of NTD risk (for rs1421085, relative risk (RR) = 0.73 (95% confidence interval (CI): 0.62, 0.87); for rs8050136, RR = 0.79 (95% CI: 0.67, 0.93); for rs9939609, RR = 0.79 (95% CI: 0.67, 0.94); and for rs17187449, RR = 0.80 (95% CI: 0.68, 0.95)). Additionally, maternal LEP rs2071045 (RR = 1.31, 95% CI: 1.08, 1.60) and offspring UCP2 rs660339 (RR = 1.32, 95% CI: 1.06, 1.64) were associated with NTD risk. Furthermore, the maternal genotype for TCF7L2 rs3814573 suggested an increased NTD risk among obese women. These findings indicate that maternal genetic variants associated with glucose homeostasis may modify the risk of having an NTD-affected pregnancy. PMID:23132673

    This study further examined the association between selected maternal occupations and a variety of birth defects identified from prior analysis and explored the effect of work hours and number of jobs held and potential interaction between folic acid and occupation. Data from a population-based, multi-center case-control study was used. Analyses included 45 major defects and specific sub-occupations under five occupational groups: healthcare workers, cleaners, scientists, teachers and personal service workers. Both logistic regression and Bayesian models (to minimize type-1 errors) were used, adjusted for potential confounders. Effect modification by folic acid was also assessed. More than any other occupation, nine different defects were positively associated with maids or janitors [odds ratio (OR) range: 1.72-3.99]. Positive associations were also seen between the following maternal occupations and defects in their children (OR range: 1.35-3.48): chemists/conotruncal heart and neural tube defects (NTDs), engineers/conotruncal defects, preschool teachers/cataracts and cleft lip with/without cleft palate (CL/P), entertainers/athletes/gastroschisis, and nurses/hydrocephalus and left ventricular outflow tract heart defects. Non-preschool teachers had significantly lower odds of oral clefts and gastroschisis in their offspring (OR range: 0.53-0.76). There was a suggestion that maternal folic acid use modified the effects with occupations including lowering the risk of NTDs and CL/P. No consistent patterns were found between maternal work hours or multiple jobs by occupation and the risk of birth defects. Overall, mothers working as maids, janitors, biologists, chemists, engineers, nurses, entertainers, child care workers and preschool teachers had increased risks of several malformations and non-preschool teachers had a lower risk of some defects. Maternal folic acid use reduced the odds of NTDs and CL/P among those with certain occupations. This hypothesis

    The risk of certain birth defects can be modified by maternal diet. A high-fat maternal mouse diet has recently been reported to substantially increase the penetrance of birth defects known to be associated with a deficiency of transcription factor Cited2 as well as induce cleft palate. These effects were associated with a more than twofold reduction in embryonic expression of Pitx2c. This investigation suggests the need to further explore this provocative gene-diet interaction in human studies.

  16. Prevention of preterm birth.

    LENUS (Irish Health Repository)

    Flood, Karen

    2012-02-01

    Preterm birth (delivery before 37 completed weeks of gestation) is common and rates are increasing. In the past, medical efforts focused on ameliorating the consequences of prematurity rather than preventing its occurrence. This approach resulted in improved neonatal outcomes, but it remains costly in terms of both the suffering of infants and their families and the economic burden on society. Increased understanding of the pathophysiology of preterm labor has altered the approach to this problem, with increased focus on preventive strategies. Primary prevention is a limited strategy which involves public education, smoking cessation, improved nutritional status and avoidance of late preterm births. Secondary prevention focuses on recurrent preterm birth which is the most recognisable risk factor. Widely accepted strategies include cervical cerclage, progesterone and dedicated clinics. However, more research is needed to explore the role of antibiotics and anti-inflammatory treatments in the prevention of this complex problem.

    Full Text Available Background: Some congenital defects can be prevented in the pregestational stage. However, many health professionals are not prepared to provide counselling to couples regarding the same. Objective: This study aimed to assess the performance of doctors and nurses from a primary health-care unit in Florianopolis, Brazil, in preventing birth defects in the preconception period based on the recommendations of the Control Center of Disease Prevention. Materials and Methods: This descriptive cross sectional study was performed at a tertiary referral center. In this study, a semi-structured questionnaire was provided to 160 health professionals comprising doctors and nurses who were actively involved in providing primary health care in family health programs. The non-parametric Chi-square (χ2 test was used to analyse the data obtained through multiple choice questions. Results: Our results showed that although 81.9% of health professionals provided health-care assistance based on protocols, and only 46.2% professionals were aware of the presence of the topic in the protocol. Of the recommendations provided by the Control Center of Disease Prevention, the use of folic acid was the most prescribed. However, this prescription was not statistically different between nurses and doctors (P=0.85. Conclusion: This study identified the fragile nature in these professional’s knowledge about the prevention of birth defects in pre-conception period, as evidenced by the inconsistency in their responses.

    2016-06-01

    Agricultural compounds have been detected in drinking water, some of which are teratogens in animal models. The most commonly detected agricultural compounds in drinking water include nitrate, atrazine, and desethylatrazine. Arsenic can also be an agricultural contaminant, although arsenic often originates from geologic sources. Nitrate has been the most studied agricultural compound in relation to prenatal exposure and birth defects. In several case-control studies published since 2000, women giving birth to babies with neural tube defects, oral clefts, and limb deficiencies were more likely than control mothers to be exposed to higher concentrations of drinking water nitrate during pregnancy. Higher concentrations of atrazine in drinking water have been associated with abdominal defects, gastroschisis, and other defects. Elevated arsenic in drinking water has also been associated with birth defects. Since these compounds often occur as mixtures, it is suggested that future research focus on the impact of mixtures, such as nitrate and atrazine, on birth defects. PMID:27007730

  9. Tritium releases, birth defects and infant deaths

    International Nuclear Information System (INIS)

    The AECB has published a report 'Tritium releases from the Pickering Nuclear Generating Station and Birth Defects and Infant Mortality in Nearby Communities 1971-1988' (report number INFO-0401). This presents the results of a detailed analysis of deaths and birth defects occurring in infants born to mothers living in the area (25 Km radius) of the Pickering nuclear power plant, over an 18-year period. The analysis looked at the frequency of these defects and deaths in comparison to the general rate for Ontario, and also in relation to airborne and waterborne releases of tritium from the power plant. The overall conclusion was that the rates of infant death and birth defects were generally not higher in the study population than in all of Ontario. There was no prevalent relationship between these deaths and defects and tritium releases measured either at the power plant or by ground monitoring stations t some distance from the facility

    Birth defects are a global problem, but their impact is particularly severe in low and middle income countries, where the conditions for prevention, treatment, and rehabilitation are more critical. The epidemiological transition in the infant mortality causes, and the concern of the community and the mass media about the teratogenic risk of environmental pollutants, has made health authorities aware of the importance of birth defects in Argentina. The objective of this paper is to outline those actions specifically taken in Argentina aimed at the prevention of birth defects at a national level. Firstly, we focus on birth defects in Argentina on a general basis, and then we present different laws and actions taken in terms of surveillance and public health programs, primary, secondary, and tertiary prevention. Finally, we present the Teratology Information Service "Fetal Health Line", and the genetic services organization and health professionals training by the National Center of Medical Genetics and the National Program of Genetics Network. In conclusion, in the country, several programs focus on different approaches to the problem, and the challenge is to coordinate the teamwork between them. Finally, we list tips to address birth defects from the public health perspective. PMID:25564015

    BACKGROUND Although associations between maternal parity and birth defects have been observed previously, few studies have focused on the possibility that parity is an independent risk factor for birth defects. We investigated the relation between levels of parity and a range of birth defects, adjusting each defect group for the same covariates. METHODS We included infants who had an estimated delivery date between 1997 and 2007 and participated in the National Birth Defects Prevention Study, a multisite case-control study. Cases included infants or fetuses belonging to 38 phenotypes of birth defects (n = 17,908), and controls included infants who were unaffected by a major birth defect (n = 7173). Odds ratios (ORs) were adjusted for 12 covariates using logistic regression. RESULTS Compared with primiparous mothers, nulliparous mothers were more likely to have infants with amniotic band sequence, hydrocephaly, esophageal atresia, hypospadias, limb reduction deficiencies, diaphragmatic hernia, omphalocele, gastroschisis, tetralogy of Fallot, and septal cardiac defects, with significant ORs (1.2 to 2.3). Compared with primiparous mothers, multiparous mothers had a significantly increased risk of omphalocele, with an OR of 1.5, but had significantly decreased risk of hypospadias and limb reduction deficiencies, with ORs of 0.77 and 0.77. CONCLUSIONS Nulliparity was associated with an increased risk of specific phenotypes of birth defects. Most of the phenotypes associated with nulliparity in this study were consistent with those identified by previous studies. Research into biologic or environmental factors that are associated with nulliparity may be helpful in explaining some or all of these associations. PMID:22371332

    Birth defects are one of the most common adverse birth outcomes, which create a heavy economic burden to the country, society and family. And they are also one of the biggest problems facing public health today. Polycyclic aromatic hydrocarbons (PAHs) are a group of toxic pollutants existing in the environment widely, resulting from incomplete organic matter combustion, and can be taken into the body through various ways including the digestive tract, respiratory tract and so on. Recent researches suggest that the exposure of PAHs may be associated with various birth defects, while the special mechanism isn't very clear. This paper is a review of the relationship between PAHs and birth defects from the aspects of epidemiological data, experimental evidence on animals, which indicates that exposure of PAHs during pregnancy may be associated with birth defects including congenital heart defects, neural tube defects and cleft lip/plate. Furthermore, we explored the possible mechanism, including oxidative stress, oxidative damage and the changes of signal transduction pathway in order to provide some recommendations and suggestions on the future work.

    Birth defects (structural, functional and metabolic disorder present from birth, may be diagnosed later) rising up as an important cause of infant mortality even in developing countries where infant mortality has been reduced to much extent. Seventy percent of birth defects are preventable through the application of various cost effective community genetic services. Indian people are living in the midst of risk factors for birth defects, e.g., universality of marriage, high fertility, large number of unplanned pregnancies, poor coverage of antenatal care, poor maternal nutritional status, high consanguineous marriages rate, and high carrier rate for hemoglobinopathies. India being the second most populous country with a large number infant born annually with birth defects should focus its attention on strategies for control of birth defects. Many population based strategies such as iodization, double fortification of salt, flour fortification with multivitamins, folic acid supplementation, periconceptional care, carrier screening and prenatal screening are some of proven strategies for control of birth defects. Strategies such as iodization of salt in spite of being initiated for a long time in the past do have a very little impact on its consumption (only 50% were using iodized salt). Community genetic services for control of birth defects can be easily flourished and integrated with primary health care in India because of its well established infrastructure and personnel in the field of maternal and child health care. As there is wide variation for infant mortality rate (IMR) in different states in India, so there is a need of deferential approach to implement community genetic services in states those had already achieved national goal of IMR. On the other hand, states those have not achieved the national goal on IMR priority should be given to management of other causes of infant mortality. PMID:24019610

    Background The wide range and complex combinations of factors that cause birth defects impede the development of primary prevention strategies targeted at high-risk subpopulations. Methods Latent class analysis (LCA) was conducted to identify mutually exclusive profiles of factors associated with birth defects among women between 15 and 49 years of age using data from a large, population-based, cross-sectional study conducted in Shaanxi Province, western China, between August and October, 2013. The odds ratios (ORs) and 95% confidence intervals (CIs) of associated factors and the latent profiles of indicators of birth defects and congenital heart defects were computed using a logistic regression model. Results Five discrete subpopulations of participants were identified as follows: No folic acid supplementation in the periconceptional period (reference class, 21.37%); low maternal education level + unhealthy lifestyle (class 2, 39.75%); low maternal education level + unhealthy lifestyle + disease (class 3, 23.71%); unhealthy maternal lifestyle + advanced age (class 4, 4.71%); and multi-risk factor exposure (class 5, 10.45%). Compared with the reference subgroup, the other subgroups consistently had a significantly increased risk of birth defects (ORs and 95% CIs: class 2, 1.75 and 1.21–2.54; class 3, 3.13 and 2.17–4.52; class 4, 5.02 and 3.20–7.88; and class 5, 12.25 and 8.61–17.42, respectively). For congenital heart defects, the ORs and 95% CIs were all higher, and the magnitude of OR differences ranged from 1.59 to 16.15. Conclusions A comprehensive intervention strategy targeting maternal exposure to multiple risk factors is expected to show the strongest results in preventing birth defects. PMID:27183231

  17. Birth defects in pregestational diabetes: Defect range, glycemic threshold and pathogenesis.

    Currently, 60 million women of reproductive age (18-44 years old) worldwide, and approximately 3 million American women have diabetes mellitus, and it has been estimated that this number will double by 2030. Pregestational diabetes mellitus (PGD) is a significant public health problem that increases the risk for structural birth defects affecting both maternal and neonatal pregnancy outcome. The most common types of human structural birth defects associated with PGD are congenital heart defects and central nervous system defects. However, diabetes can induce birth defects in any other fetal organ. In general, the rate of birth defects increases linearly with the degree of maternal hyperglycemia, which is the major factor that mediates teratogenicity of PGD. Stringent prenatal care and glycemic control are effective means to reduce birth defects in PGD pregnancies, but cannot reduce the incidence of birth defects to the rate of that is seen in the nondiabetic population. Studies in animal models have revealed that PGD induces oxidative stress, which activates cellular stress signalling leading to dysregulation of gene expression and excess apoptosis in the target organs, including the neural tube and embryonic heart. Activation of the apoptosis signal-regulating kinase 1 (ASK1)-forkhead transcription factor 3a (FoxO3a)-caspase 8 pathway causes apoptosis in the developing neural tube leading to neural tube defects (NTDs). ASK1 activates the c-Jun-N-Terminal kinase 1/2 (JNK1/2), which leads to activation of the unfolded protein response and endoplasmic reticulum (ER) stress. Deletion of the ASK1 gene, the JNK1 gene, or the JNK2 gene, or inhibition of ER stress by 4-Phenylbutyric acid abrogates diabetes-induced apoptosis and reduces the formation of NTDs. Antioxidants, such as thioredoxin, which inhibits the ASK1-FoxO3a-caspase 8 pathway or ER stress inhibitors, may prevent PGD-induced birth defects. PMID:25897357

    Birth defects are one of the leading causes of paediatric disability and mortality in developed and developing countries. Data on birth defects from population-based studies originating from developing countries are lacking. One of the objectives of this study was to determine the epidemiology of major birth defects in births during the perinatal period in Kinta district, Perak, Malaysia over a 14-month period, using a population-based birth defect register. There were 253 babies with major birth defects in 17,720 births, giving an incidence of 14.3/1000 births, a birth prevalence of 1 in 70. There were 80 babies with multiple birth defects and 173 with isolated birth defects. The exact syndromic diagnosis of the babies with multiple birth defects could not be identified in 18 (22.5%) babies. The main organ systems involved in the isolated birth defects were cardiovascular (13.8%), cleft lip and palate (11.9%), clubfeet (9.1%), central nervous system (CNS) (including neural tube defects) (7.9%), musculoskeletal (5.5%) and gastrointestinal systems (4.7%), and hydrops fetalis (4.3%). The babies with major birth defects were associated with lower birth weights, premature deliveries, higher Caesarean section rates, prolonged hospitalization and increased specialist care. Among the cohort of babies with major birth defects, the mortality rate was 25.2% during the perinatal period. Mothers with affected babies were associated with advanced maternal age, birth defects themselves or their relatives but not in their other offspring, and significantly higher rates of previous abortions. The consanguinity rate of 2.4% was twice that of the control population. It is concluded that a birth defects register is needed to monitor these developments and future interventional trials are needed to reduce birth defects in Malaysia. PMID:16096215

    Full Text Available 94% of all birth defects (BD and 95% of deaths due to the BD occur in low and middle income countries, many of which are preventable. In Tanzania, there is currently a paucity of BD data necessary to develop data informed prevention activities. Methods A cross-sectional analysis was conducted of deliveries identified with BD in the labor ward registers at four Dar es Salaam hospitals between October, 2011 and February, 2012. The birth prevalence of structural BD, case fatality proportion, and the distribution of structural defects associated deaths within total deaths were calculated. A total of 28 217 resident births were encountered during the study period. Overall birth prevalence of selected defects was 28.3/10 000 live births. Neural tube defects and indeterminate sex were the most and least common defects at birth (9.9 and 1.1/10 000 live births respectively. Among stillbirths (66.7% and deaths that occurred within less than 5 days of an affected live birth (18.5%, neural tube defects were the most frequently associated structural defect. Structural BD is common and contributes to perinatal mortality in Dar es Salaam. More than half of perinatal deaths encountered among the studied selected external structural BD are associated with neural tube defects, a birth defect with well–established evidence based prevention interventions. By establishing a population–based BD surveillance program, Tanzania would have the information about neural tube defects and other major structural BD needed to develop and monitor prevention activities.

    2007-01-01

    There are many surveillance systems of congenital defects all over the world; several of them have developed specific approaches to generate and test selected hypotheses regarding human teratogens. However, to the best of our knowledge, none of them have a permanent and systematised programme for the study of the risk and safety of drugs. The aim of this article is to describe the research programme on the potential effects of drugs in pregnancy followed by the Spanish Collaborative Study of Congenital Malformations (ECEMC), which is a permanent ongoing case-control study and surveillance system. The programme to analyse drugs includes a continuous and systematic study on the potential effects of medicines used during pregnancy. This programme has several characteristics that make it different from other current systems: (i) the collection of numerous datapoints (up to 312 per infant) in a case-control design; (ii) the use of a versatile and specific coding of birth defects; (iii) a specific programme for the continuous analysis of the potential effects of each type of drugs used during pregnancy that has been developed specifically for the ECEMC methodology, including its dysmorphological coding system. The description of the ECEMC's approach to surveillance of the effects of drug use during pregnancy may help researches in this area, particularly those using data from birth defects registries.

In this dissertation the plausibility of using data on all birth defects, available from birth defects registries, as a surrogate for the spatial distribution of all live births in the analysis of clusters is assessed. Three spatial statistics that have been applied in epidemiologic investigations of clusters, nearest neighbor distance, average interpoint distance, and average distance to a fixed point, were evaluated by computer simulation for their properties in a unit square, and in a zip code region. Comparison of spatial distributions of live births and birth defects was performed by drawing samples of live births and birth defects from Santa Clara County, determining the street address at birth, geocoding this address and evaluating the resultant maps using various statistical techniques. The proposed method was then demonstrated on a previously confirmed cluster of oral cleft cases. All live births for the neighborhood were geocoded, as were all birth defects. Evaluation of this cluster using the nearest neighbor and average interpoint distance statistics was performed using randomization techniques with both the live births population and the birth defect population as comparison groups. 113 refs., 36 figs., 16 tabs.

    Earlier studies by our group suggested the possibility that offspring of pesticide appliers might have increased risks of birth anomalies. To evaluate this hypothesis, 935 births to 34,772 state-licensed, private pesticide appliers in Minnesota occurring between 1989 and 1992 were linked to the Minnesota state birth registry containing 210,723 live births in this timeframe. The birth defect rate for all birth anomalies was significantly increased in children born to private appliers. Specific...

  1. Links between environmental geochemistry and rate of birth defects: Shanxi Province, China

    International Nuclear Information System (INIS)

    The rate of birth defects in Shanxi Province is among the highest worldwide. In order to identify the impacts of geochemical and environmental factors on birth defect risk, samples of soil, water and food were collected from an area with an unusually high rate of birth defects (study area) and an area with a low rate of birth defects (control area) in Shanxi Province, China. Element contents were determined by ICP-OES, and the results were analyzed using a non-parametric test and stepwise regression. Differences in the level and distribution of 14 geochemical elements, namely arsenic (As), selenium (Se), molybdenum (Mo), zinc (Zn), strontium (Sr), iron (Fe), tin (Sn), magnesium (Mg), vanadium (V), calcium (Ca), copper (Cu), aluminum (Al), potassium (K) and sulfur (S) were thus compared between the study and control areas. The results reveal that the geochemical element contents in soil, water and food show a significant difference between the study area and control area, and suggest that the study area was characterized by higher S and lower Sr and Al contents. These findings, based on statistical analysis, may be useful in directing further epidemiological investigations identifying the leading causes of birth defects. - Research Highlights: → Environmental geochemistry has an significant impact on birth defects in the regions with an unusually high rate of birth defects. → An excess of S and deficiency of Sr and Al are the distinctive environmental features associated with the high rate of birth defects in the Shanxi Province of China. → Geochemical anomalies is a non-medical basis for effective prevention and cure of birth defects.

    2010-12-01

    Full Text Available Since 2003, congenital malformations have increased to account for 15% of all births in Fallujah, Iraq. Congenital heart defects have the highest incidence, followed by neural tube defects. Similar birth defects were reported in other populations exposed to war contaminants. While the causes of increased prevalence of birth defects are under investigation, we opted to release this communication to contribute to exploration of these issues. By using a questionnaire, containing residential history and activities that may have led to exposure to war contaminants, retrospective reproductive history of four polygamous Fallujah families were documented. Our findings point to sporadic, untargeted events, with different phenotypes in each family and increased recurrence. The prevalence of familial birth defects after 2003 highlights the relevance of epigenetic mechanisms and offers insights to focus research, with the aim of reducing further damage to people’s health.

    Full Text Available Neural tube defects (NTDs, serious birth defects of the brain and spine usually resulting in death or paralysis, affect an estimated 300,000 births each year worldwide. Although the majority of NTDs are preventable with adequate folic acid consumption during the preconception period and throughout the first few weeks of gestation, many populations, in particular those in low and middle resource settings, do not have access to fortified foods or vitamin supplements containing folic acid. Further, accurate birth defects surveillance data, which could help inform mandatory fortification and other NTD prevention initiatives, are lacking in many of these settings. The burden of birth defects in South East Asia is among the highest in the world. Expanding global neural tube defects prevention initiatives can support the achievement of the United Nations Millennium Development Goal 4 to reduce child mortality, a goal which many countries in South East Asia are currently not poised to reach, and the 63rd World Health Assembly Resolution on birth defects. More work is needed to develop and implement mandatory folic acid fortification policies, as well as supplementation programs in countries where the reach of fortification is limited.

    Full Text Available Objective. Preterm birth (PTB remains a major cause of neonatal morbidity and mortality. The association between PTB and infection is clear. The purpose of this report is to present a focused review of information on the use of antibiotics to prevent PTB. Methods. We performed a search of the PubMed database restricted to clinical trials or meta-analyses published in English from 1990 through May 2011 using keywords “antibiotics or antimicrobials” and “preterm.” Results. The search yielded 67 abstracts for review. We selected 31 clinical trials (n=26 or meta-analysis (n=5 for further full-text review. Discussion of each eligible clinical trial, its specific inclusion criteria, antibiotic regimen used, and study results are presented. Overall, trials evaluating antibiotic treatment to prevent preterm birth have yielded mixed results regarding any benefit. Conclusion. Routine antibiotic prophylaxis is not recommended for prevention of preterm birth.

    Since more and more women in developed countries are delaying childbearing to an older age, it is important to find out whether birth defects, other than those resulting from chromosomal anomalies, are related to maternal age. We have studied all 26,859 children with birth defects of unknown aetiology identified among 576,815 consecutive livebirths in British Columbia. All these cases' records were linked with provincial birth records to allow determination of maternal age at birth. We excluded children with chromosomal anomalies and those with other birth defects of known aetiology. Only 3 of the 43 birth defect categories studied showed significant maternal-age-specific trends: there were decreasing linear trends with maternal age for patent ductus arteriosus (chi 2 = 36.65, 1 df, p less than 0.01) and hypertrophic pyloric stenosis (chi 2 = 4.90, 1 df, p less than 0.05) and a bell-shaped curve (risk increasing to maternal age 30 then falling) for congenital dislocatable hip/hip click. The findings from this population-based analysis of no association between the incidence of birth defects of unknown aetiology and advancing maternal age should be reassuring to healthy women who opt to delay childbearing.

    Full Text Available Birth defects or congenital anomalies are one of the major causes of disability in developed and developing countries. Data on birth defects from population-based studies originating from developing countries are lacking. Increasingly there is a shift to genetic testing and genomics study of birth defects. However the translation from bench findings to bedside medicine has been muted. There is a need to address this imbalance where congenital anomalies remained the top aetiology for neonatal mortality in developing countries. To build capacity in low resource countries, there is a need for accurate collection and ascertainment of birth defects in developing countries. The systematic collection and analysis of data on major birth defects using birth defects registries (BDR are an integral part of all clinical genetic services. Healthcare planners in developing countries must be aware of the advantages and limitations of BDRs. Despite the advent of the genomics era, BDRs are essential to the planning and developing care and prevention services at local and national levels, particularly in low resource or developing countries.

  13. Zika virus and birth defects: an obstetric issue

    Full Text Available Zika virus is an emerging mosquito-borne virus that is relatively unknown, unstudied and under-diagnosed, but has potentials to spread to new geographical areas that favour survival of Aedes mosquitoes. It is associated with an alarming rise in babies with microcephaly that require much care and support with a lot of financial assistance. This is a review article on Zika virus and birth defects; a worrisome issue in today's obstetric and medical practices. Since Zika's discovery in Uganda, the virus was known to occur within a narrow equatorial belt from Africa to Asia with no or mild symptoms. It has emerged as a global public health threat over the last decade with accelerated geographic spread of the virus in the last nine years. The risk of Zika virus to the fetus is poorly understood, difficult to quantify and problematic. The causal link between Zika virus and microcephaly was initially speculative, strongly suspected and scientifically unproven. However, on 13th April, 2016, it was concluded that Zika virus is the cause of microcephaly and other severe fetal brain defects. The Center for Disease Control and Prevention (CDC authors reviewed and weighed evidences using established scientific criteria to conclude after a careful review of the report published in the New England Journal of Medicine. There is no prophylaxis, treatment or vaccine to protect against Zika virus infection. However, preventive personal measures are highly recommended to avoid mosquito bites.

    2014-03-01

    Full Text Available Objective: To assess the prevalence of congenital defects and to investigate their maternal and perinatal associated aspects by reviewing Birth Certificates. Methods: Among all born alive infants from January 2003 to December 2007 in Maternidade da Santa Casa de Misericórdia of São Carlos, Southeast Brazil (12,199 infants, cases were identified as the newborns whose Birth Certificates registered any congenital defect. The same sex neonate born immediately after the case was chosen as a control. In total, 13 variables were analyzed: six were maternal related, three represented labor and delivery conditions and four were linked to fetal status. The chi-square and Fisher's exact tests were used to compare the variables, being significant p<0.05. Results: The prevalence of congenital defects was 0.38% and the association of two or more defects represented 32% of all cases. The number of mothers whose education level was equal or less than eight years was significantly higher among the group with birth defects (p=0.047. A higher frequency of prematurity (p<0.001 and cesarean delivery (p=0.004 was observed among children with birth defects. This group also showed lower birth weight and Apgar scores in the 1st and the 5th minute (p<0.001. Conclusions: The prevalence of congenital defect of 0.38% is possibly due to underreporting. The defects notified in the Birth Certificates were only the most visible ones, regardless of their severity. There is a need of adequate epidemiological monitoring of birth defects in order to create and expand prevention and treatment programs.

    This study assessed the reliability of birth certificate data related to birth defects in Brazil's Live Birth Information System (SINASC). We selected 24 maternity hospitals in the Unified National Health System (SUS) and compared the reports of birth defects from birth certificates with medical records of mothers and live born infants in the city of Rio de Janeiro for the year 2004. After transposing the data to a specific form, the birth defects were coded by types and organ systems and compared to the SINASC data. The most commonly affected organs involved the central nervous and musculoskeletal systems. Agreement was more than 50% for the digestive, genitourinary, and musculoskeletal systems and chromosomal anomalies. Prevalence-adjusted kappa varied according to 2 or 3-digit ICD-10 analysis, with better results for the musculoskeletal, digestive, and genitourinary systems and congenital anomalies, and worse for the central nervous and cardio-circulatory systems, eye, neck, and ear malformations, and cleft lip and palate. The results were unsatisfactory, suggesting the need for more investments to train the persons responsible for completing birth certificates in maternity hospitals and develop a model for coding birth defects on these documents.

    Birth defects surveillance systems collect population-based birth defects data from multiple sources to track trends in prevalence, identify risk factors, refer affected families to services, and evaluate prevention efforts. Strong state and federal public health and legal mandates are in place to govern the collection and use of these data. Despite the prima facie appeal of "opt-in" and similar strategies to those who view data collection as a threat to privacy, the use of these strategies in lieu of population-based surveillance can severely limit the ability of public health agencies to accurately access the health status of a group within a defined geographical area. With the need for population-based data central to their mission, birth defects programs around the country take their data stewardship role seriously, recognizing both moral and legal obligations to protect the data by employing numerous safeguards. Birth defects surveillance systems are shaped by the needs of the community they are designed to serve, with the goal of preventing birth defects or alleviating the burdens associated with them.

    Indian people are living in the midst of risk factors for birth defects, e.g., universality of marriage, high fertility, large number of unplanned pregnancies, poor coverage of antenatal care, poor maternal nutritional status, high consanguineous marriages rate, and high carrier rate for hemoglobinopathies. India being the second most populous country with a large number infant born annually with birth defects should focus its attention on strategies for control of birth defects. Many population based strategies such as iodization, double fortification of salt, flour fortification with multivitamins, folic acid supplementation, periconceptional care, carrier screening and prenatal screening are some of proven strategies for control of birth defects. Strategies such as iodization of salt in spite of being initiated for a long time in the past do have a very little impact on its consumption (only 50% were using iodized salt. Community genetic services for control of birth defects can be easily flourished and integrated with primary health care in India because of its well established infrastructure and personnel in the field of maternal and child health care. As there is wide variation for infant mortality rate (IMR in different states in India, so there is a need of deferential approach to implement community genetic services in states those had already achieved national goal of IMR. On the other hand, states those have not achieved the national goal on IMR priority should be given to management of other causes of infant mortality.

    Objective To investigate the association between birth defects and dietary nutrient intake in a high risk area of China.Methods A dietary survey was performed and serum folic acid was measured in women whose pregnancy was affected by neural tube defects(NTDs)or unaffected by any birth defects(BDs)in Zhongyang and Jiaokou Counties in Shanxi Province of China.Results The local average censureption of foods including dark green vegetables,fluits,fat and meat,and nutrient intake(e.g.energy,protein,retinol,riboflavin,vitamin E,and selenium)were lower than the national average level.In women of childbearing age,these regions,the intake of nutrients was much lower than the recommended nutrient intake(9%-77%)The case-centrel dietary nutrition smdv of women whose pregnancy was affected bv BDs(including MTDs and congenital heart defects)demonstrated that,in early pregnancy,adequate nutrition(I.e.eating meat,fresh vegetables,fruit more than once a week)was a protective factor,while eating germinated potatoes was a risk factor.The geometrical mean(p5-p95)of serum folic acid in women with NTD birth defects was 9.6 nmol/L(3.6,23.03),which was significantly lower than that in normal women(14.03 nmol/L). Conclusion Wemen of childbearing age in the two counties of Shanxi Province,Chim,have a marked insufficient intake of some nutrients,especially folic acid,zinc,vitamins A and B12.This nutrient deficiency may be an important risk factor for the high prevalence of birth defects in these regions.Therefore,adequate dietary nutrition in early pregnancy can prevent BDs.

    OBJECTIVE The purpose of this study was to examine the risk of birth defects in relation to diabetes mellitus and the lack of use of periconceptional vitamins or supplements that contain folic acid. STUDY DESIGN The National Birth Defects Prevention Study (1997-2004) is a multicenter, population-based case-control study of birth defects (14,721 cases and 5437 control infants). Cases were categorized into 18 types of heart defects and 26 noncardiac birth defects. We estimated odds ratios for independent and joint effects of preexisting diabetes mellitus and a lack of periconceptional use of vitamins or supplements that contain folic acid. RESULTS The pattern of odds ratios suggested an increased risk of defects that are associated with diabetes mellitus in the absence vs the presence of the periconceptional use of vitamins or supplements that contain folic acid. CONCLUSION The lack of periconceptional use of vitamins or supplements that contain folic acid may be associated with an excess risk for birth defects due to diabetes mellitus. PMID:22284962

    Structural birth defects in the kidney and urinary tract are observed in 0.5% of live births and are a major cause of end-stage renal disease, but their genetic aetiology is not well understood. Here we analyse 135 lines of mice identified in large-scale mouse mutagenesis screen and show that 29% of mutations causing congenital heart disease (CHD) also cause renal anomalies. The renal anomalies included duplex and multiplex kidneys, renal agenesis, hydronephrosis and cystic kidney disease. To assess the clinical relevance of these findings, we examined patients with CHD and observed a 30% co-occurrence of renal anomalies of a similar spectrum. Together, these findings demonstrate a common shared genetic aetiology for CHD and renal anomalies, indicating that CHD patients are at increased risk for complications from renal anomalies. This collection of mutant mouse models provides a resource for further studies to elucidate the developmental link between renal anomalies and CHD. PMID:27002738

    1993-01-01

    Despite years of research, the etiology of most birth defects remains largely unknown. Interview instruments have been the major tools in the search for environmental causes of birth defects. Because of respondents' problems with recognition and recall, interviews are limited in their capacity to measure certain exposures. Laboratory scientists can have a major impact on defining markers of environmental exposure and genetic susceptibility. The Centers for Disease Control is starting a case-control study of serious birth defects on the basis of a population-based surveillance system for birth defects diagnosed during the first year of life in metropolitan Atlanta, Each year, 300 infants with selected birth defects (case subjects) and 100 population-based control subjects (infants without birth defects) will be enrolled in an ongoing study that will supplement surveillance. In addition to conducting extensive maternal interviews, we will collect blood and urine specimens from case and control subjects and their mothers for laboratory testing. Eventually, some environmental sampling may be incorporated. Particular areas of emphasis are (1) nutritional factors, specifically measuring maternal folic acid levels and other micronutrients (e.g., zinc) to explore their role in the etiology of neural tube defects, (2) substance use, specifically measuring cocaine metabolites in the blood and urine to explore their role for specific vascular disruption defects, and (3) environmental factors such as pesticides and aflatoxins, to explore their potential relationships with specific defects. In addition, a DNA bank will be maintained to evaluate the role of specific candidate genes in the etiology of birth defects. The development and testing of these methods could be useful to assess the interaction between environmental exposures and genetic susceptibility in the etiology of birth defects. 15 refs., 1 fig., 1 tab.

    Preterm birth is the most important cause of neonatal mortality and morbidity worldwide. In this review, we review potential risk factors associated with preterm birth and the subsequent management to prevent preterm birth in low and high risk women with a singleton or multiple pregnancy. A history of preterm birth is considered the most important risk factor for preterm birth in subsequent pregnancy. General risk factors with a much lower impact include ethnicity, low socio-economic status, maternal weight, smoking, and periodontal status. Pregnancy-related characteristics, including bacterial vaginosis and asymptomatic bacteriuria, appear to be of limited value in the prediction of preterm birth. By contrast, a mid-pregnancy cervical length measurement is independently associated with preterm birth and could be used to identify women at risk of a premature delivery. A fetal fibronectin test may be of additional value in the prediction of preterm birth. The most effective methods to prevent preterm birth depend on the obstetric history, which makes the identification of women at risk of preterm birth an important task for clinical care providers.

    Full Text Available OBJECTIVES: 1 To understand the current prevalence and main types of birth defects, 2 assess the periconceptional exposure of factors associated with birth defects in Shaanxi Province, and 3 provide scientific evidence for local governments to formulate services for the primary prevention of birth defects. METHODS: We sampled 16,541 households from 128 townships in 16 counties/districts in Shaanxi province using a multi-stage random sampling method. Among them, 10,544 women who had live born or stillborn infants with gestational age ≥ 28 weeks between 2008 and 2009 were interviewed using a structured questionnaire designed to collect information about periconceptional risk factor exposure, health care service utilization, and micronutrient supplements. Logistic regression was performed to assess the risk factors associated with birth defects and adjustments were made for imbalanced social-demographic characteristics between case and control groups. RESULTS: The prevalence of congenital birth defect in Shaanxi province was 14.3/1000 births. The environment risk factors associated with birth defects include unhealthy lifestyle (Alcohol, odds ratio (OR: 3.60, 95% confidence interval (CI 1.64-7.91; Smoking, OR: 1.32, 95% CI: 0.99-1.75; Drink strong tea, OR: 1.81, 95% CI: 1.27-2.59, exposure to heavy pollution (OR: 1.53, 95% CI: 1.01-2.30, maternal diseases (OR: 1.77, 95% CI: 1.35-2.33, drug use (OR: 2.11, 95% CI: 1.51-2.95, maternal chemical pesticide exposure (OR: 2.30, 95% CI: 1.16-4.57, and adverse pregnancy history (OR: 10.10, 95% CI: 7.55-13.53.

  11. An exploratory analysis of the relationship between ambient ozone and particulate matter concentrations during early pregnancy and selected birth defects in Texas

    International Nuclear Information System (INIS)

    We performed an exploratory analysis of ozone (O3) and fine particulate matter (PM2.5) concentrations during early pregnancy and multiple types of birth defects. Data on births were obtained from the Texas Birth Defects Registry (TBDR) and the National Birth Defects Prevention Study (NBDPS) in Texas. Air pollution concentrations were previously determined by combining modeled air pollution concentrations with air monitoring data. The analysis generated hypotheses for future, confirmatory studies; although many of the observed associations were null. The hypotheses are provided by an observed association between O3 and craniosynostosis and inverse associations between PM2.5 and septal and obstructive heart defects in the TBDR. Associations with PM2.5 for septal heart defects and ventricular outflow tract obstructions were null using the NBDPS. Both the TBDR and the NBPDS had inverse associations between O3 and septal heart defects. Further research to confirm the observed associations is warranted. - Highlights: • Air pollution concentrations combined modeled air data and air monitoring data. • No associations were observed between the majority of birth defects and PM2.5 and O3. • Estimated associations between PM2.5 and certain heart defects varied by dataset. • Results were suggestive of an inverse association between O3 and septal heart defects. • Higher O3 concentrations may be associated with increased odds of craniosynostosis. - Although most observed associations between ozone and fine particulate matter concentrations and birth defects were null, some were present and warrant further consideration

    Purpose Early detection of hearing loss in all newborns and timely intervention are critical to children's cognitive, verbal, behavioral, and social development. The initiation of appropriate early intervention services before 6 months of age can prevent or reduce negative developmental consequences. The purpose of this study was to assess, using large, population-based registries, the effect of co-occurring birth defects (CBDs) on the timing and overall rate of hearing screening and diagnosis. Method The authors linked statewide data from newborn hearing screenings, a birth defects registry, and birth certificates to assess the timeliness of newborn hearing screening and diagnosis of hearing loss (HL) for infants with and without CBDs in 485 children with confirmed HL. Results Nearly one third (31.5%) of children with HL had 1 or more CBDs. The presence of CBDs prolonged the time of the initial infant hearing screening, which contributed to further delays in the subsequent diagnosis of HL. Conclusions Better coordination of HL assessment into treatment plans for children with CBDs may enable earlier diagnosis of HL and provide opportunities for intervention that will affect long-term developmental outcomes for these children.

    Full Text Available Diet, particularly vitamin deficiency, is associated with the risk of birth defects. The aim of this review paper is to show the characteristics of common and severe neural-tube defects together with congenital heart defects (CHD as vitamin deficiencies play a role in their origin. The findings of the Hungarian intervention (randomized double-blind and cohort controlled trials indicated that periconceptional folic acid (FA-containing multivitamin supplementation prevented the major proportion (about 90% of neural-tube defects (NTD as well as a certain proportion (about 40% of congenital heart defects. Finally the benefits and drawbacks of three main practical applications of folic acid/multivitamin treatment such as (i dietary intake; (ii periconceptional supplementation; and (iii flour fortification are discussed. The conclusion arrived at is indeed confirmation of Benjamin Franklin’s statement: “An ounce of prevention is better than a pound of care”.

    The objective of the study is to determine the proportion and different types of birth defects among the children born in Hospital Kuala Lumpur. A cross-sectional study was conducted for a period of 18 months where all consecutively born infants, dead or alive were included. There were total of 34,109 births recorded during this period. The proportion of birth defects in Hospital Kuala Lumpur was 3.1% (n = 1056). The commonest involved were the hematology system, (157.7 per 10,000 births), the central nervous system, genitourinary system and chromosomal anomalies. The proportion was significantly higher in males and in the Chinese (p defect is common and ranked second after G6PD deficiency. There is a need for a birth defect registry to assess the extent of the problem in Malaysia. PMID:16570708

    Full Text Available Abstract Background South Africa is one of the major users of pesticides on the African continent. The Eastern Cape is the second largest province in South Africa. There has been growing concern about the occurrence of certain birth defects which seemed to have increased in the past few years. In this paper we investigate associations between exposure to agricultural chemicals and certain birth defects. Few such studies have been undertaken in the developing world previously. Methods Between September 2000 and March 2001 a case – control study was conducted among rural women in the area of the Eastern cape to investigate the association between women's exposure to pesticides and the occurrence of birth defects. Information on birth defects was obtained from the register of the Paediatrics Department at the Cecilia Makiwane Hospital in Mdantsane, one of the largest referral hospitals in the province. The cases were children who were diagnosed with selected birth defects. The controls were children born in the same areas as the cases. Exposure information on the mothers was obtained by interview concerning from their activities in gardens and fields. Data were analysed using conditional logistic regression. Results A total of 89 case mothers and 178 control mothers was interviewed. Babies with birth defects were seven times more likely to be born to women exposed to chemicals used in gardens and fields compared to no reported exposure (Odds Ratio 7.18, 95% CI 3.99, 13.25; and were almost twice as likely to be born to women who were involved in dipping livestock used to prevent ticks (OR 1.92, 95% CI 1.15, 3.14. They were also 6.5 times more likely to be born to women who were using plastic containers for fetching water (OR 6.5, 95% CI 2.2, 27.9. Some of these containers had previously contained pesticides (OR 1.87, 95% CI 1.06, 3.31. Conclusions These findings suggest a link between exposure to pesticides and certain birth defects among the

    1988-01-01

    Ergotamine exposure during pregnancy has been suggested to cause birth defects which have a vascular disruptive aetiology. The present case provides additional support for the possible adverse fetal effects of exposure to ergotamine, caffeine, and propranolol during the first four months of pregnancy. At birth the infant showed evidence of early arrested cerebral maturation and paraplegia. The nature of these defects suggests a primary vascular disruptive aetiology. We hypothesise that ergota...

  12. Defect Prevention Based on 5 Dimensions of Defect Origin

    Directory of Open Access Journals (Sweden)

    Sakthi Kumaresh

    2012-08-01

    Full Text Available “Discovering the unexpected is more important than confirming the known [7]. In software development,the “unexpected” one relates to defects. These defects when unattended would cause failure to the productand risk to the users. The increasing dependency of society on software and the crucial consequences that afailure can cause requires the need to find out the defects at the origin itself. Based on the lessons learntfrom the earlier set of projects, a defect framework highlighting the 5 Dimensions (Ds of defect origin isproposed in this work. The defect framework is based on analyzing the defects that had emerged fromvarious stages of software development like Requirements, Design, Coding, Testing and Timeline (defectsdue to lack of time during development. This study is not limited to just identifying the origin of defects atvarious phases of software development but also finds out the reasons for such defects, and defectpreventive (DP measures are proposed for each type of defect. This work can help practitioners chooseeffective defect avoidance measures.In addition to arriving at defect framework, this work also proposes a defect injection metric based onseverity of the defect rather than just defect count, which gives the number of adjusted defects produced bya project at various phases. The defect injection metric value, once calculated, serves as a yardstick tomake a comparison in the improvements made in the software process development between similar set ofprojects

    Researchers analyzed data on 66,743 births which occurred between 1985-1989 in the Styria region in southern Austria to determine whether radioactive fallout from the meltdown of the nuclear reaction at Chernobyl in the Ukraine, USSR in may 1986 affected the birth defect and abortion rates in this area of Austria. There were 1695 birth defect cases. Of the birth defects which occurred during embryogenesis, most occurred 14-49 days postconception (group 2; n=630). The researchers did not note a short-term effect of the fallout in group 2 or the other groups (relative risk= 0.75, 0.73 for group 1, and 0.93 for group 2). Baseline birth defect rates (per 1000 births) for groups 1, 2, and 3 were 2.5, 8.5, and 1,8 respectively. The only sizable increase occurred in group 2 at years 2 and 3 (10.6 and 10.3, respectively). More reported minor congenital defect cases accounted for this increase due to the newly established data base in the Department of Pediatric Cardiology at the University of Graz. Thus the increase was an artifact and not a true increase. Abortion rates varied from 10% to 14% and did not increase significantly after Chernobyl. Counseling frequency at abortion clinics fluctuated greatly (117-205) both before and after Chernobyl and the changes were not significant. These results indicated that the low dosage of radiation did not have a detectable biologic effect in terms of birth defects and abortions. The researchers addressed the difficulties with measuring teratologic potential of low dose radiation. They also highlighted the need for accurate categorizing of birth defects, adequate baseline data, and very reliable registries. Future research on possible environmental disasters which affect Austria can use these data as baseline data. PMID:1415387

    Our aim was to provide a descriptive overview of how the birth defects surveillance and folic acid fortification programs were implemented in Costa Rica-through the establishment of the Registry Center for Congenital Anomalies (Centro de Registro de Enfermedades Congénitas-CREC), and fortification legislation mandates. We estimated the overall prevalence of neural tube defects (i.e., spina bifida, anencephaly and encephalocele) before and after fortification captured by CREC. Prevalence was calculated by dividing the total number of infants born with neural tube defects by the total number of live births in the country (1987-2012).A total of 1,170 newborns with neural tube defects were identified from 1987 to 2012 (1992-1995 data excluded); 628 were identified during the baseline pre-fortification period (1987-1991; 1996-1998); 191 during the fortification period (1999-2002); and 351 during the post-fortification time period (2003-2012). The overall prevalence of neural tube defects decreased from 9.8 per 10,000 live-births (95 % CI 9.1-10.5) for the pre-fortification period to 4.8 per 10,000 live births (95 % CI 4.3-5.3) for the post-fortification period. Results indicate a statistically significant (P < 0.05) decrease of 51 % in the prevalence of neural tube defects from the pre-fortification period to the post-fortification period. Folic acid fortification via several basic food sources has shown to be a successful public health intervention for Costa Rica. Costa Rica's experience can serve as an example for other countries seeking to develop and strengthen both their birth defects surveillance and fortification programs. PMID:24952876

    Since the protective effect of folic acid (FA) on birth defects is well known, it is reasonable to assume intrauterine exposure to FA antagonists increases the risk on these defects.

    The purpose of this study was to examine whether dichorionic twins conceived by assisted reproductive technology (ART; intracytoplasmic sperm injection [ICSI], in vitro fertilization [IVF], gamete-intrafallopian tube transfer [GIFT]) have a higher risk of birth defects compared to dichorionic twins conceived naturally. We reviewed the medical records of 406 mothers with dichorionic twin pregnancies, who received continuous antenatal care from or = 24 weeks of gestation in our institute. Birth defects were diagnosed at the time of hospital discharge according to the International Classification of Diseases, 10th Revision. Occurrence of birth defects was compared between twins conceived by ART and those conceived naturally using logistic regression analysis. Overall, 51 of 812 infants (51/812 = 6.2%) had birth defects. The incidence of birth defects in ART-conceived twins was significantly higher than that of naturally conceived twins with an odds ratio of 6.9 (95% confidence interval [CI] 2.1, 22.5), 3.7 (95% CI 1.2, 12.0), and 4.3 (95% CI 1.4, 14.3) for ICSI, IVF, and GIFT, respectively. The higher frequency of birth defects in ART-conceived twins was still significant after adjusting for higher maternal age in the ART group, with an adjusted odds ratio of 6.7 (95% CI 2.1, 21.9), 3.6 (95% CI 1.1, 11.5), and 3.7 (95% CI 1.2-11.8) for ICSI, IVF, and GIFT, respectively. Dichorionic twins conceived by ART, compared to dichorionic twins conceived naturally, had a much higher risk for birth defects diagnosed at hospital discharge. PMID:15193165

    Full Text Available Abstract Background Birth Defects are a series of diseases that seriously affect children's health. Birth defects are generally caused by several interrelated factors. The aims of the article is to estimate the prevalence rate and types of birth defects in Inner Mongolia, China, to compare socio-demographic characteristics among the children with birth defects and to analyze the association between risk factors and birth defects. Methods Data used in this study were obtained through baseline survey of Inner Mongolia Birth Defects Program, a population-based survey conducted from 2005 to 2008. The survey used cluster sampling method in all 12 administrative districts of Inner Mongolia. Sampling size is calculated according to local population size at a certain percentage. All live births, stillbirths and abortions born from October 2005 to September 2008, whose families lived in Inner Mongolia at least one year, were included. The cases of birth defects were diagnosed by the clinical doctors according to their experiences with further laboratory tests if needed. The inclusion criteria of the cases that had already dead were decided according to death records available at local cites. We calculated prevalence rate and 95% confidence intervals of different groups. Outcome variable was the occurrence of birth defects and associations between risk factors and birth defects were analyzed by using Poisson regression analysis. Results 976 children with birth defects were diagnosed. The prevalence rate of birth defects was 156.1 per 10000 births (95%CI: 146.3-165.8.

  1. Association between risk of birth defects occurring level and arsenic concentrations in soils of Lvliang, Shanxi province of China

    International Nuclear Information System (INIS)

    The risk of birth defects is generally accredited with genetic factors, environmental causes, but the contribution of environmental factors to birth defects is still inconclusive. With the hypothesis of associations of geochemical features distribution and birth defects risk, we collected birth records and measured the chemical components in soil samples from a high prevalence area of birth defects in Shanxi province, China. The relative risk levels among villages were estimated with conditional spatial autoregressive model and the relationships between the risk levels of the villages and the 15 types of chemical elements concentration in the cropland and woodland soils were explored. The results revealed that the arsenic levels in cropland soil showed a significant association with birth defects occurring risk in this area, which is consistent with existing evidences of arsenic as a teratogen and warrants further investigation on arsenic exposure routine to birth defect occurring risk. - Highlights: • Association between soil geochemical components and birth defects risk was proposed. • The relative risk difference among villages were estimated with CAR model. • Arsenic levels in cropland showed a significant association to birth defect risk. • The finding warrants further investigation on arsenic as a teratogen. - The difference of risk levels estimate by spatial statistics to birth defect significantly associated with arsenic levels in cropland soils warrants further investigation

    Full Text Available Abstract An increased prevalence of birth defects was allegedly reported in Iraq in the post 1991 Gulf War period, which was largely attributed to exposure to depleted uranium used in the war. This has encouraged further research on this particular topic. This paper reviews the published literature and provided evidence concerning birth defects in Iraq to elucidate possible environmental exposure. In addition to published research, this review used some direct observation of birth defects data from Al-Ramadi Maternity and Paediatric Hospital in Al-Anbar Governorate in Iraq from1st July 2000 through 30th June 2002. In addition to depleted uranium other war-related environmental factors have been studied and linked directly or indirectly with the increasing prevalence of birth defects. However, the reviewed studies and the available research evidence do not provide a clear increase in birth defects and a clear indication of a possible environmental exposure including depleted uranium although the country has been facing several environmental challenges since 1980.

    Effective prevention of preterm birth is one of the unsolved problems in modern medicine. In the Thuringia campaign 2000 based on a simple screening with intravaginal pH self-measurements, adequate medical diagnosis and immediate antimicrobial therapy of genital infection, the rate of newborns methods, do we really have to wait even more decades to come for a prospectively randomized double-blinded almost impracticable study to convince the latest skeptical scientist that we have plenty of evidence-based means to reduce the incidence of premature birth, now, by decreasing infectious morbidity in pregnancy and by the same action childbed fever as well? Insisting scholastically on nothing but the 100 % pure evidence sometimes can hamper innovations and potential benefit. Would a similar caution ever had allowed us for instance to introduce handwashing according to Semmelweis? Good news, the Government of the State of Thuringia has decided this year to reestablish a pH selfcare screening programme. PMID:27146862

    A case-control study was conductedin 36 hospitals of the urban and suburban areas of Shanghai about the relationships between birth defects and drug use and chemieal exposures during pregnancy in the period of July 1987-December 1990. The case group was composed of 1.609 subjects, and the control group 3,218 cases. On statistical analysis, it was found that a correlation existed between birth defects and the intake of APC and diazepam, and the exposure to pesticides, organic soh, ents, benzene, synthetic resin and physical factors (noises) on the part of the mother, and the exposure to harmful chemicals and physical factors and the smoking of 20 or more cigarettes a day on the part of the father. It is also found that the familial hereditary history of the parents and muhigravidio,, malnutrition, common colds, hepatitis and diarrhea during pregnancy may also be related to the birth defects.

    Cardiac surgery in neonates with congenital heart disease has progressed dramatically in the past three decades. However, low-birth-weight neonates with congenital heart disease continue to challenge the intellectual and technical skills of healthcare professionals. We present a case of a low-birth-weight neonate with pulmonary atresia and a ventricular septal defect, in whom palliation was achieved with a right ventricular outflow tract stent using a hybrid procedure.

    Full Text Available Defects are most detrimental entities which deter the smooth operation and deployment of the software system and can arise in any part of the life cycle, they are most feared, but still Defect Prevention is mostly discounted field of software quality. Unattended defects cause a lot of rework and waste of effort. Hence only finding the defects is not important, finding the root cause of the defect is also important which is quite difficult due to levels of abstraction in terms of people, process, complexity, environment and other factors. Through this study various techniques of Defect classification, prevention and root cause analysis are analysed. The intent of this paper is to demonstrate the structured process showing defect prevention flow and inferring three T's (Tracking, Technique and Training after analysis.

    Full Text Available Most of the software projects fail to meet the desired level of quality and standards due to different types of defects introduced during the course of requirement solicitation, designing and development. These defects inexorably hinder the secure deployment or smooth operations of the software systems. One of the key reasons for this misfortune is the lack of proper defect prevention planning while formulating the software architecture. Defect prevention needs to be a thorough and critical phase because it has a direct impact on quality of the product which cannot be compromised. This paper looks into different defect prevention techniques and analyses them critically. The scope of this study is restricted to the identification of the modern trends in defect prevention

    International Nuclear Information System (INIS)

    Objective: To understand the status of birth defects among the perinatal infants in the areas contiguous to Hongyanhe nuclear power plant before its normal operation, so as to provide background information for the evaluation of the impact of nuclear power plant on birth defects. Methods: From 1 October 1995 to 30 September 2009 the midwifery units at second class and above of Wafangdian City were asked to be in charge of recording the birth defects among the perinatal infants born during this period within the range of 50 km around the Hongyanhe nuclear power plant. Results: The total number of birth defects was 697, and the maternal number Was 83779. The average defect rate Was 83.20/104. There were significant differences in the birth defect rate among different years (χ2=39.54, P<0.05), however, without linear trend therein,and among the survey areas (χ2=15.36, P<0.05) as well. The top five birth defects were congenital heart disease (148 cases), cleft lip with cleft palate (67 cases), congenital hydrocephalus (63 cases), and spina bifida (37 cases) and cleft lip (36 cases). Conclusions: The birth defect rate within the range of 50 km around the Hongyanhe nuclear power plant is lower than that of the region of Liaoning Province and the national rate of birth defects.

    Exposures to particulate matter with diameter of 2.5µm or less (PM2.5) may influence risk of birth defects. We estimated associations between maternal exposure to prenatal traffic-related air pollution and risk of cardiac, orofacial, and neural tube defects among Massachusetts births conceived 2001 through 2008. Our analyses included 2729 cardiac, 255 neural tube, and 729 orofacial defects. We used satellite remote sensing, meteorological and land use data to assess PM2.5 and traffic-related exposures (distance to roads and traffic density) at geocoded birth addresses. We calculated adjusted odds ratios (OR) and confidence intervals (CI) using logistic regression models. Generalized additive models were used to assess spatial patterns of birth defect risk. There were positive but non-significant associations for a 10µg/m(3) increase in PM2.5 and perimembranous ventricular septal defects (OR=1.34, 95% CI: 0.98, 1.83), patent foramen ovale (OR=1.19, 95% CI: 0.92, 1.54) and patent ductus arteriosus (OR=1.20, 95% CI: 0.95, 1.62). There was a non-significant inverse association between PM2.5 and cleft lip with or without palate (OR=0.76, 95% CI: 0.50, 1.10), cleft palate only (OR=0.89, 95% CI: 0.54, 1.46) and neural tube defects (OR=0.77, 95% CI: 0.46, 1.05). Results for traffic related exposure were similar. Only ostium secundum atrial septal defects displayed significant spatial variation after accounting for known risk factors. PMID:26705853

    Our population-based case-control study of air quality and birth defects in Texas relied on the geocoding of maternal residence from vital records for the assignment of air pollution exposures during early pregnancy. We attempted to geocode the maternal addresses for 5,338 birth defect cases and 4,574 frequency-matched controls using an automated procedure with standard matching criteria in ArcGIS 8.2 and 8.3. Initially, we matched 7,266 observations (73%). To increase the proportion of successful matches, we used an interactive procedure for the 2,646 addresses that were initially not geocoded by the software. This yielded an additional 985 matches (37%). Using the same 2,646 initially unmatched addresses, we compared the results of this interactive procedure to those of an automated procedure using lower standards. The automated procedure with lower standards yielded more matches (n=1,559, 59%) but with questionable accuracy. We included the interactively geocoded observations in our final data set. Their inclusion did not affect the estimates of air pollution exposure but increased our statistical power to detect associations between air quality and risk of selected birth defects. The geocoded and not geocoded populations differed in the distribution of Latino ethnicity (51% vs 59%) and ethnicity was independently associated with air pollution exposures (Pbirth defects; Latina women appeared to have a slightly lower risk of birth defects than non-Latina women in the geocoded population and to have a slightly higher risk in the not geocoded population. Incomplete geocoding may have resulted in a selection bias because of the under-representation of Latinas in our study population. PMID:16483563

    In 1992, the U.S. Public Health Service recommended that all women capable of becoming pregnant consume 400 µg of folic acid daily to prevent neural tube defects (NTDs). NTDs are major birth defects of the brain and spine that occur early in pregnancy as a result of improper closure of the embryonic neural tube, which can lead to death or varying degrees of disability. The two most common NTDs are anencephaly and spina bifida. Beginning in 1998, the United States mandated fortification of enriched cereal grain products with 140 µg of folic acid per 100 g. Immediately after mandatory fortification, the birth prevalence of NTD cases declined. Fortification was estimated to avert approximately 1,000 NTD-affected pregnancies annually. To provide updated estimates of the birth prevalence of NTDs in the period after introduction of mandatory folic acid fortification (i.e., the post-fortification period), data from 19 population-based birth defects surveillance programs in the United States, covering the years 1999-2011, were examined. After the initial decrease, NTD birth prevalence during the post-fortification period has remained relatively stable. The number of births occurring annually without NTDs that would otherwise have been affected is approximately 1,326 (95% confidence interval = 1,122-1,531). Mandatory folic acid fortification remains an effective public health intervention. There remain opportunities for prevention among women with lower folic acid intakes, especially among Hispanic women, to further reduce the prevalence of NTDs in the United States. PMID:25590678

    目的 探讨出生缺陷的状况及其影响因素,为降低出生缺陷干预措施的制定提供依据.方法 回顾性监测分析我院2001年1月至2010年12月10年间分娩的围产儿出生缺陷状况.结果 10年监测17 365例围产儿,其中出生缺陷儿205例,平均出生缺陷发生率为11.81‰,总体出生缺陷的年度发生率间无显著性差异(χ2=4.303,P=0.890>0.05),但2006年至2010年与2001年至2005年相比,神经管畸形的构成比明显下降(17.09%vs29.55%,χ2=4.474,P=0.034 0.05 ). But compared with the period of 2001-2005, the constituent ratio of neural tube defect at the period of 2006-2010 decreased significantly ( 17.09% vs 29. 55% ,χ2 = 4. 474,P = 0.034 <0.05,OR =0. 492 ). The first 5 types of birth defect were neural tube defect, polysyndactyly, cheilopalatognathus, urinary tract defect and congenital cardiopathy in turn, and the incidence rates of them were 2. 66 , 2.49 , 1. 22 , 1. 10 and 0. 98 , respectively. The sum of incidence of the first three types occupied 52. 69% of overall birth defect rate. The age of puerperants (x = 14. 946,P =0.000 <0. 05,OR = 1.712 ) and the gender of perinatal infants (χ2 = 6.488 ,P = 0. 011 <0. 05, OR = 1.440 ) were closely related with birth defect. There were 52. 20% of birth defect diagnosed before birth, and B-ultrasound was the main method for diagnosing ( 57. 07% ). Conclusion The incidence rate of birth defect in the area needs to be cut down, especially the types of neural tube defects, polysyndactyly and cheilopalatognathus. Low-dose of folic acid has significant effect in preventing neural tube defects.

    Full Text Available We examined the association of occupational exposure to handling cytotoxic drugs at work with risk of birth defects among a cohort of female veterinarians. This study is a follow up survey of 321 female participants (633 pregnancies who participated in the Health Risks of Australian Veterinarian project. Data on pregnancies and exposure during each pregnancy was obtained by self-administered mailed questionnaire. Female veterinarians handling cytotoxic drugs during their pregnancy had a two-fold increased risk of birth defects in their offspring (RR = 2.08, 95% CI (1.05–4.15. Results were consistent in subgroup analysis of those who graduated during the period of 1961 to 1980 (RR = 5.04, 95% CI (1.81, 14.03 and in those working specifically in small and large animal practice. There was no increased risk in the subgroup that graduated after 1980. Women with unplanned pregnancies were more likely to handle cytotoxic drugs on a daily basis (RR = 1.86, 95% CI, 1.00–3.48 and had a higher increased risk of birth defects than those who planned their pregnancies in recent graduates and in those who worked specifically in small animal practice (RR = 2.53, 95% CI, 1.18–5.42. This study suggests that the adverse effects of handling cytotoxic drugs in pregnant women may include an increased risk of birth defects. Pregnancy intention status is an important health behavior and should be considered in prenatal programs.

  13. Birth defects risk associated with maternal sport fish consumption: potential effect modification by sex of offspring

    International Nuclear Information System (INIS)

    Contaminated sport fish consumption may result in exposure to various reproductive and developmental toxicants, including pesticides and other suspected endocrine disruptors. We investigated the relation between maternal sport fish meals and risk of major birth defects among infants born to members of the New York State (NYS) Angler Cohort between 1986 and 1991 (n=2237 births). Birth defects (n=125 cases) were ascertained from both newborn medical records and the NYS Congenital Malformations Registry. For sport fish meals eaten during pregnancy, the odds ratio (OR) for all major malformations combined was slightly elevated for ≤1 meal/month (OR=1.26, 95% confidence interval (CI): 0.84, 1.89) and ≥2 meals/month (OR=1.51, CI=0.74, 3.09), with no meals during pregnancy as the reference category. Higher ORs were consistently observed among male offspring compared with females. For ≥2 meals/month, the risk for males was significantly elevated (males: OR=3.01, CI: 1.2, 7.5; females: OR=0.73, CI: 0.2, 2.4). Exposure during pregnancy and effect modification by infants sex could be important considerations for future studies of birth outcomes associated with endocrine disruptors

    Full Text Available BACKGROUND: Antiretroviral therapy (ART has major benefits during pregnancy, both for maternal health and to prevent mother-to-child transmission of HIV. Safety issues, including teratogenic risk, need to be evaluated. We estimated the prevalence of birth defects in children born to HIV-infected women receiving ART during pregnancy, and assessed the independent association of birth defects with each antiretroviral (ARV drug used. METHODS AND FINDINGS: The French Perinatal Cohort prospectively enrolls HIV-infected women delivering in 90 centers throughout France. Children are followed by pediatricians until 2 y of age according to national guidelines. We included 13,124 live births between 1994 and 2010, among which, 42% (n = 5,388 were exposed to ART in the first trimester of pregnancy. Birth defects were studied using both European Surveillance of Congenital Anomalies (EUROCAT and Metropolitan Atlanta Congenital Defects Program (MACDP classifications; associations with ART were evaluated using univariate and multivariate logistic regressions. Correction for multiple comparisons was not performed because the analyses were based on hypotheses emanating from previous findings in the literature and the robustness of the findings of the current study.

    Full Text Available Jodie M Dodd, Caroline A CrowtherDiscipline of Obstetrics and Gynaecology, The University of Adelaide, Adelaide, South Australia, AustraliaAbstract: Preterm birth continues to provide an enormous challenge in the delivery of perinatal health care, and is associated with considerable short and long-term health consequences for surviving infants. Progesterone has a role in maintaining pregnancy, by suppression of the calcium–calmodulin–myosin light chain kinase system. Additionally, progesterone has recognized anti-inflammatory properties, raising a possible link between inflammatory processes, alterations in progesterone receptor expression and the onset of preterm labor. Systematic reviews of randomized controlled trials evaluating the use of intramuscular and vaginal progesterone in women considered to be at increased risk of preterm birth have been published, with primary outcomes of perinatal death, preterm birth <34 weeks, and neurodevelopmental handicap in childhood. Eleven randomized controlled trials were included in the systematic review, involving 2714 women and 3452 infants, with results presented according to the reason women were considered to be at increased risk of preterm birth. While there is a potential beneficial effect in the use of progesterone for some women considered to be at increased risk of preterm birth, primarily in the reduction in the risk of preterm birth before 34 weeks gestation, it remains unclear if the observed prolongation of pregnancy translates into improved health outcomes for the infant.Keywords: progesterone, preterm birth, systematic review, randomized trial

    Full Text Available In the last two decades, India has witnessed a substantial decrease in infant mortality attributed to infectious disease and malnutrition. However, the mortality attributed to birth defects remains constant. Studies on the prevalence of birth defects such as neural tube defects and orofacial clefts in India have reported inconsistent results. Therefore, we conducted a systematic review of observational studies to document the birth prevalence of neural tube defects and orofacial clefts.A comprehensive literature search for observational studies was conducted in MEDLINE and EMBASE databases using key MeSH terms (neural tube defects OR cleft lip OR cleft palate AND Prevalence AND India. Two reviewers independently reviewed the retrieved studies, and studies satisfying the eligibility were included. The quality of included studies was assessed using selected criteria from STROBE statement.The overall pooled birth prevalence (random effect of neural tube defects in India is 4.5 per 1000 total births (95% CI 4.2 to 4.9. The overall pooled birth prevalence (random effect of orofacial clefts is 1.3 per 1000 total births (95% CI 1.1 to 1.5. Subgroup analyses were performed by region, time period, consanguinity, and gender of newborn.The overall prevalence of neural tube defects from India is high compared to other regions of the world, while that of orofacial clefts is similar to other countries. The majority of studies included in the review were hospital based. The quality of these studies ranged from low to moderate. Further well-designed, high quality community-based observational studies are needed to accurately estimate the burden of neural tube defects and orofacial clefts in India.

    Several epidemiological studies link pesticide exposure to reproductive and developmental toxicity. However, additional studies have shown little or no evidence to support such relationship. On the other hand, experimental data show that some pesticides may indeed alter the reproductive function or produce birth defects (as evidenced by intrauterine death, in utero growth retardation, visceral and skeletal malformations or functional deficits) in laboratory animals. This review is a critical analysis of the epidemiological and experimental evidence available to date, that links pesticide exposure with induction of reproductive or developmental defects. Factors that must be considered when establishing a cause-effect relationship are also discussed, including the shape of the dose-response curve, exposure to pesticides in chemical mixtures and the influence of genetic background.

    The software industry is successful, if it can draw the complete attention of the customers towards it. This is achievable if the organization can produce a high quality product. To identify a product to be of high quality, it should be free of defects, should be capable of producing expected results. It should be delivered in an estimated cost, time and be maintainable with minimum effort. Defect Prevention is the most critical but often neglected component of the software quality assurance in any project. If applied at all stages of software development, it can reduce the time, cost and resources required to engineer a high quality product.

  13. Epidemiology of birth defects, perinatal mortality and thyroid cancer before and after the Chernobyl catastrophe

    International Nuclear Information System (INIS)

    Spatial and temporal trends of birth defects and perinatal mortality in Germany and Europe as well as in least and most contaminated regions have been compared and investigated by trends. In numerous data sets, especially from northern and eastern Europe, positive and significant trend variations with upward 'disturbances' in temporal relation associated with the Chernobyl accident 1986 have been identified and spatial associations with regional fallout have been found. A surprisingly consistent picture evolves of significantly raised stillbirth rates after Chernobyl of ca. 5 % in Poland, ca. 10 % in parts of Germany and Sweden, ca. 20 % in Denmark and Finland, and up to ca. 30% in Iceland and Hungary. Low as compared to higher contaminated regions show weaker or stronger effects, respectively. The additional relative risks for birth defects are in the same order of magnitude as the additional relative risks for stillbirth, namely 0,5%-20 %/kBq·m2. Using well-known conversion coefficients, the excess relative risk of 1 %/kBq·m2 translates theoretically to a preliminary relative risk of 1,6/mSv/a. The incidence of thyroid carcinoma among children affected by Chernobyl fallout has increased dramatically in certain parts of Europe. Less evidence exists for a similar effect among adolescents and adults. The cancer registry of the Czech Republic provides an opportunity to study various determinants of the occurrence of thyroid cancer. After the Chernobyl accident, the thyroid cancer incidence of the Czech Republic reveals an additional annual increase of up to 5% depending on age and gender. The additional increases of thyroid cancer in the whole population of the Czech Republic are consistent with reports from other countries. To investigate trends in the sex distribution of newborns before and after the Chernobyl accident, gender-specific annual birth statistics were obtained from the Czech Republic, Denmark, Finland, Germany, Hungary, Norway, Poland, and Sweden

    While the preterm neonate continues to benefit from improved perinatal care, the rate of preterm birth in the United States remains significant. An increasing body of scientific literature has demonstrated the benefits of maternal progesterone administration in reducing primary and recurrent preterm birth. Intramuscular hydroxyprogesterone caproate is indicated in singleton pregnancies in women with a prior spontaneous preterm birth, while vaginal progesterone demonstrates similar efficacy in prolonging pregnancy in women with asymptomatic cervical shortening in the midtrimester. Given these favorable benefits, the use of progesterone has been expanded to other clinical situations at risk for preterm birth with less rigorous scientific evidence. This review highlights the current evidence-based clinical applications of progesterone for prevention of preterm birth. PMID:26788788

    In most of population dynamics, increases in population due to birth are assumed to be time-dependent, but many species reproduce only during a single period of the year. In this paper, we propose an epidemic model with density-dependent birth pulses and seasonal prevention. Using the discrete dynamical system determined by stroboscopic map, we obtain the local or global stability, numerical simulation shows there is a characteristic sequence of bifurcations, leading to chaotic dynamics, which implies that the dynamical behaviors of the epidemic model with birth pulses and seasonal prevention are very complex, including small amplitude oscillations, large-amplitude multi-annual cycles and chaos. This suggests that birth pulse, in effect, provides a natural period or cyclicity that may lead a period-doubling route to chaos.

  19. Research on prevention of defects in electron beam welding

    International Nuclear Information System (INIS)

    As for electron beam welding, the application to superthick walled structures such as reactor pressure vessels has been investigated, to utilize the characteristics of deep penetration and small deformation. In this research, the method of preventing welding defects which are apt to be formed when the deep penetration characteristics are utilized was examined in both aspects of welding parameter control and the addition of alloy elements using filler materials. Concerning the method by welding parameter control, the prevention of defects at penetration root, the improvement of back bead and the prevention of swelling at the middle of penetration accompanied by cracks and blowholes were examined. Concerning the method of adding filler materials, the method of dispersing added elements uniformly in weld metal was investigated. On the basis of these results, the addition of filler materials to the welded part of high carbon steel for preventing the hardening and cracking was attempted, and its effectiveness was examined. As the result, by controlling the amount of addition of filler materials and posterior heat treatment, the welded parts corresponding to the conditions of use were obtained, and it was confirmed that the addition of filler materials was able to be utilized effectively.

    Maternal diabetes mellitus is a significant risk factor for structural birth defects, including congenital heart defects and neural tube defects. With the rising prevalence of type 2 diabetes mellitus and obesity in women of childbearing age, diabetes mellitus-induced birth defects have become an increasingly significant public health problem. Maternal diabetes mellitus in vivo and high glucose in vitro induce yolk sac injuries by damaging the morphologic condition of cells and altering the dynamics of organelles. The yolk sac vascular system is the first system to develop during embryogenesis; therefore, it is the most sensitive to hyperglycemia. The consequences of yolk sac injuries include impairment of nutrient transportation because of vasculopathy. Although the functional relationship between yolk sac vasculopathy and structural birth defects has not yet been established, a recent study reveals that the quality of yolk sac vasculature is related inversely to embryonic malformation rates. Studies in animal models have uncovered key molecular intermediates of diabetic yolk sac vasculopathy, which include hypoxia-inducible factor-1α, apoptosis signal-regulating kinase 1, and its inhibitor thioredoxin-1, c-Jun-N-terminal kinases, nitric oxide, and nitric oxide synthase. Yolk sac vasculopathy is also associated with abnormalities in arachidonic acid and myo-inositol. Dietary supplementation with fatty acids that restore lipid levels in the yolk sac lead to a reduction in diabetes mellitus-induced malformations. Although the role of the human yolk in embryogenesis is less extensive than in rodents, nevertheless, human embryonic vasculogenesis is affected negatively by maternal diabetes mellitus. Mechanistic studies have identified potential therapeutic targets for future intervention against yolk sac vasculopathy, birth defects, and other complications associated with diabetic pregnancies.

    Full Text Available O impacto dos defeitos congênitos no Brasil vem aumentando progressivamente, tendo passado da quinta para a segunda causa dos óbitos em menores de um ano entre 1980 e 2000, apontando para a necessidade de estratégias específicas na política de saúde. Foram localizadas, no Brasil, direcionadas aos defeitos congênitos, ações governamentais e não-governamentais. Estas envolvem serviços de informação sobre agentes teratogênicos na gravidez e sobre doenças metabólicas geneticamente determinadas, monitorização de defeitos congênitos, programa de triagem neonatal e tratamento de algumas doenças genéticas, imunização contra rubéola, além da fortificação de farinhas com ácido fólico como ação preventiva de certos defeitos congênitos. Apesar da importância de tais iniciativas, é pouco provável que seja possível atender à questão dos defeitos congênitos de forma integrada. Para a efetivação de um sistema de atenção voltado aos defeitos congênitos, deverá ser formulada política específica, de âmbito nacional, com a participação ativa do Ministério da Saúde, utilizando, como espinha dorsal, os serviços de genética existentes. Só assim, será possível a estruturação de uma rede regionalizada, hierarquizada e funcional voltada à atenção aos defeitos congênitos no Brasil.Birth defects have increased progressively in Brazil, shifting from the fifth to the second cause of infant mortality from 1980 to 2000, thus highlighting the need for specific health policy strategies.

    2006-11-30

    Software for automated test equipment can be tedious and monotonous making it just as error-prone as other software. Active defect prevention and detection are also important for test applications. Incomplete or unclear requirements, a cryptic syntax used for some test applications—especially script-based test sets, variability in syntax or structure, and changing requirements are among the problems encountered in one tester. Such problems are common to all software but can be particularly problematic in test equipment software intended to test another product. Each of these issues increases the probability of error injection during test application development. This report describes a test application development tool designed to address these issues and others for a particular piece of test equipment. By addressing these problems in the development environment, the tool has powerful built-in defect prevention and detection capabilities. Regular expressions are widely used in the development tool as a means of formally defining test equipment requirements for the test application and verifying conformance to those requirements. A novel means of using regular expressions to perform range checking was developed. A reduction in rework and increased productivity are the results. These capabilities are described along with lessons learned and their applicability to other test equipment software. The test application development tool, or “application builder”, is known as the PT3800 AM Creation, Revision and Archiving Tool (PACRAT).

    Full Text Available Abstract Background 15% of multiple pregnancies ends in a preterm delivery, which can lead to mortality and severe long term neonatal morbidity. At present, no generally accepted strategy for the prevention of preterm birth in multiple pregnancies exists. Prophylactic administration of 17-alpha hydroxyprogesterone caproate (17OHPC has proven to be effective in the prevention of preterm birth in women with singleton pregnancies with a previous preterm delivery. At present, there are no data on the effectiveness of progesterone in the prevention of preterm birth in multiple pregnancies. Methods/Design We aim to investigate the hypothesis that 17OHPC will reduce the incidence of the composite neonatal morbidity of neonates by reducing the early preterm birth rate in multiple pregnancies. Women with a multiple pregnancy at a gestational age between 15 and 20 weeks of gestation will be entered in a placebo-controlled, double blinded randomised study comparing weekly 250 mg 17OHPC intramuscular injections from 16–20 weeks up to 36 weeks of gestation versus placebo. At study entry, cervical length will be measured. The primary outcome is composite bad neonatal condition (perinatal death or severe morbidity. Secondary outcome measures are time to delivery, preterm birth rate before 32 and 37 weeks, days of admission in neonatal intensive care unit, maternal morbidity, maternal admission days for preterm labour and costs. We need to include 660 women to indicate a reduction in bad neonatal outcome from 15% to 8%. Analysis will be by intention to treat. We will also analyse whether the treatment effect is dependent on cervical length. Discussion This trial will provide evidence as to whether or not 17OHPC-treatment is an effective means of preventing bad neonatal outcome due to preterm birth in multiple pregnancies.

  13. Exposure to non-steroidal anti-inflammatory drugs during pregnancy and the risk of selected birth defects: a prospective cohort study.

    Directory of Open Access Journals (Sweden)

    Marleen M H J van Gelder

    Full Text Available BACKGROUND: Since use of non-steroidal anti-inflammatory drugs (NSAIDs during pregnancy is common, small increases in the risk of birth defects may have significant implications for public health. Results of human studies on the teratogenic risks of NSAIDs are inconsistent. Therefore, we evaluated the risk of selected birth defects after prenatal exposure to prescribed and over-the-counter NSAIDs. METHODS AND FINDINGS: We used data on 69,929 women enrolled in the Norwegian Mother and Child Cohort Study between 1999 and 2006. Data on NSAID exposure were available from a self-administered questionnaire completed around gestational week 17. Information on pregnancy outcome was obtained from the Medical Birth Registry of Norway. Only birth defects suspected to be associated with NSAID exposure based upon proposed teratogenic mechanisms and previous studies were included in the multivariable logistic regression analyses. A total of 3,023 women used NSAIDs in gestational weeks 0-12 and 64,074 women did not report NSAID use in early pregnancy. No associations were observed between overall exposure to NSAIDs during pregnancy and the selected birth defects separately or as a group (adjusted odds ratio 0.7, 95% confidence interval 0.4-1.1. Associations between maternal use of specific types of NSAIDs and the selected birth defects were not found either, although an increased risk was seen for septal defects and exposure to multiple NSAIDs based on small numbers (2 exposed cases; crude odds ratio 3.9, 95% confidence interval 0.9-15.7. CONCLUSIONS: Exposure to NSAIDs during the first 12 weeks of gestation does not seem to be associated with an increased risk of the selected birth defects. However, due to the small numbers of NSAID-exposed infants for the individual birth defect categories, increases in the risks of specific birth defects could not be excluded.

  17. Tritium releases from the Pickering Nuclear Generating Station and birth defects and infant mortality in nearby communities 1971-1988

    International Nuclear Information System (INIS)

    This study was commissioned to examine whether there were elevated rates of stillbirth, birth defects, or death in the first year of life between 1971 and 1988 among offspring of residents of communities within a 25-kilometre radius of the Pickering Nuclear Generating Station. The study was also to investigate whether there were any statistical associations between the monthly airborne or waterborne tritium emissions from the Pickering Nuclear Generating Station and the rates of these reproductive outcomes. Overall analysis did not support a hypothesis of increased rates of stillbirths, neonatal mortality or infant mortality near the Pickering Nuclear Generating Station, or a hypothesis of increased birth prevalence of birth defects for 21 of 22 diagnostic categories. The prevalence of Down Syndrome was elevated in both Pickering and Ajax; however, there was no consistent pattern between tritium release levels and Down Syndrome prevalence, chance could not be ruled out for the associations between Down Syndrome and tritium releases or ground-monitored concentrations, the association was detected in an analysis where multiple testing was done which may turn up significant associations by change, and maternal residence at birth and early in pregnancy needs to be verified. The association between Down Syndrome and low-level radiation remains indeterminate when existing evidence from epidemiological studies is summed. The estimated radiation exposure from the nuclear plant for residents of Pickering and Ajax is lower by a factor of 100 than the normal natural background radiation. Further study is recommended.

    Full Text Available Introduction: The shift in epidemic trends in recent years in Romania shows new problems in regard of HIV vertical transmission, firstly in intravenous drug user's mothers co-infected with hepatitis viruses and with social problems, and secondly the children of young mothers with an old HIV infection and long antiretroviral therapy history. Materials and Methods: We studied all HIV perinatal exposed children routinely followed up in the Paediatric Department of the National Institute of Infectious Diseases, since January 1st 2006 till December 31st 2012. The analyses consisted of describing the birth defects and association with certain risk factors: gender, mother's age at birth and exposure to antiretrovirals in the first trimester of pregnancy. Results: We analyzed 244 children born to HIV-infected mothers. The incidence of HIV infection was 16.39%. The rate of birth defects was 39.34% (96/244 cases. The most frequent findings were cardiac malformations (47/96, followed by musculoskeletal defects (24/96, neurologic defects (20/96, urogenital malformations (13/96, digestive tract defects (3/93, metabolic disorders (2/96 and genetic disorders (2/96. We found nine cases of severe congenital anomalies: complex heart defect, total congenital aganglionic megacolon, anal imperforation, Dandy-Walker syndrome, gangliosidosis, Niemann-Pick syndrome, Down syndrome, true hermaphroditism and cleft palate. Two children died during first year of life due to severe malformations. 9% of cases had associated malformations. The gender rate was in favour of males in group with birth defects (58/38 and with no birth defects (82/66. The median age at birth in mothers was 22 years, similar in both groups. The highest mean age at birth was in offspring's mothers with neurologic congenital defects 25, 15 years old, but is not statistically significant (p=0.1. In the studied period the highest number of birth defects were found in 2012, 37 children, compared with less

    Objective To understand the incidence of birth defect in 0-1 years old baby in some regions of Jieyang, then to determine the focus groups for prevention. So that it can provide a foundation for birth defect prevention, pre-pregnancy and pregnancy care. Methods Those babies, who were born in Jiedong County, Puning City and Rongcheng District from March 3, 2011 to May 2, 2012 were surveyed by general investigation. Birth defect based on clinical diagnosis, its entity and statistical standard referred to the regulations of International Centre on Birth Defects and Prematurity. Results 238 cases of birth defect babies were found out of 10 773 cases of monitored new babies. The top five diseases of baby birth defects were congenital heart disease, talipes equinovarus, polydactyly, cleft lip and palate and fetal-edematous-syndrome. Some babies had higher incidence of birth defects, such as baby boy, low birth weight baby, and those babies whose mother did not take folic acid, vitamin and trace elements during pregnancy and whose family members smoking and excessive drinking (P < 0.05). Conclusion The incidence rate of birth defects in 0-1 years old baby is 220.92 per ten thousand in some regions of Jieyang City. It is slightly higher than the national average, so it needs attention from each side.

    Mutations in fibroblast growth factor receptors (FGFRs) cause human birth defect syndromes and are associated with a variety of cancers. Although forced expression of mutant activated FGFRs has been shown to oncogenically transform some immortal cell types, their activity in primary cells remains unclear. Here, we show that birth defect and cancer-associated FGFR2 mutants promote DNA-damage signaling and p53-dependent senescence in primary mouse and human cells. Senescence promoted by FGFR mu...

    Based on the 5782 cases of patients from the Attached of Obstetrical and Gynecological Hospital of Zhejiang University , the paper analyzes the impacts of pregnant age and birth order on the fetal defect rate as well as impacts of the fetal defect on the population quality at the policy of two-children for all families. It is found that the pregnant age lower than 19 and older than 35 can cause the increase of fetal defect rate , while the birth order impact the birth defect rate in different ways , the higher the birth order is , for those mothers younger than 24 , the higher rate of birth defect and for the mothers aged 25-44 there is no increase of birth defect rate for their second and third child birth but with a relatively higher birth defects for their fourth child birth. It seems that the birth defect rate of second child have no negative impacts on population quality even after the permit of second child birth for all families in future.%本研究通过抽取浙江大学医学院附属妇产科医院某病区5782个病例(736例患病),从出生缺陷的角度,通过对妇女怀孕年龄及胎次与胎儿畸形患病率的关系对开放二胎政策之后的人口质量的影响进行分析,发现孕妇年龄过低(19岁以下)与过高(35岁以上)均会导致出生缺陷率提高;而胎次的影响比较复杂,对于24岁以下的年龄段来说,胎次越高,患病率越高,而对于25-44岁的孕妇来说,除了第4胎及以上的患病率较高,第2、3胎的患病率没有明显的差别。因此,放开二胎将不会对人口质量产生显著影响。

    2004-10-01

    Promotion of folic acid to prevent neural Tube Defects (NTD) has been ongoing for ten years in Ireland, without a concomitant reduction in the total birth prevalence of NTD. The effectiveness of folic acid promotion as the sole means of primary prevention of NTD is therefore questionable. We examined trends in folic acid knowledge and peri-conceptional use from 1996-2002 with the aim of assessing the value of this approach. From 1996-2002, 300 women attending ante-natal clinics in Dublin hospitals annually were surveyed regarding their knowledge and use of folic acid. During the period the proportion who had heard of folic acid rose from 54% to 94% between 1996 and 2002 (c2 test for trend: p<0.001). Knowledge that folic acid can prevent NTD also rose from 21% to 66% (c2 test for trend: p<0.001). Although the proportion who took folic acid during pregnancy increased from 14% to 83% from 1996 to 2002 (c2 test for trend: p<0.001), peri-conceptional intake did not rise above 24% in any year. There is a high awareness of folic acid and its relation to NTD, which is not matched by peri-conceptional uptake. The main barrier to peri-conceptional uptake is the lack of pregnancy planning. To date promotional campaigns appear to have been ineffective in reducing the prevalence of NTD in Ireland. Consequently, fortification of staple foodstuffs is the only practical and reliable means of primary prevention of NTD.

Previous studies have identified a prior early spontaneous preterm birth as the risk factor with the highest predictive value for recurrence. Two recent double blind randomized placebo controlled trials reported lower preterm birth rate with the use of either intramuscular 17 alpha-hydroxyprogesterone caproate (IM 17OHP-C or intravaginal micronized progesterone suppositories in women at risk for preterm delivery. However, it is still unclear which high-risk women would truly benefit from this treatment in a general clinical setting and whether socio-cultural, racial and genetic differences play a role in patient’s response to supplemental progesterone. In addition the patient’s acceptance of such recommendation is also in question. More research is still required on identification of at risk group, the optimal gestational age at initiation, mode of administration, dose of progesterone and long-term safety.Keywords: preterm birth prevention, 17-alpha-hydroxyprogesterone caproate

    Full Text Available Neural tube defects, in particular spina bifida and anencephaly, are serious and relatively common congenital abnormalities worldwide. They also occur in South Africa and affect all population groups to varying degrees. The overall incidence in South Africa is approximately 1-2 per 1000 newborns. Higher incidences, up to 6 per 1000 newborns have been recorded in certain parts, especially in some rural areas of the country. In total as many as 1500 newborns could be affected by a neural tube defect each year. The precise aetiology of neural tube defects is still unknown.

  12. Prevention of neural tube defects with folic acid: The Chinese experience.

    Neural tube defects (NTDs) are a group of congenital malformations of the central nervous system that are caused by the closure failure of the embryonic neural tube by the 28(th) day of conception. Anencephaly and spina bifida are the two major subtypes. Fetuses with anencephaly are often stillborn or electively aborted due to prenatal diagnosis, or they die shortly after birth. Most infants with spina bifida are live-born and, with proper surgical treatment, can survive into adulthood. However, these children often have life-long physical disabilities. China has one of the highest prevalence of NTDs in the world. Inadequate dietary folate intake is believed to be the main cause of the cluster. Unlike many other countries that use staple fortification with folic acid as the public health strategy to prevent NTDs, the Chinese government provides all women who have a rural household registration and who plan to become pregnant with folic acid supplements, free of charge, through a nation-wide program started in 2009. Two to three years after the initiation of the program, the folic acid supplementation rate increased to 85% in the areas of the highest NTD prevalence. The mean plasma folate level of women during early and mid-pregnancy doubled the level before the program was introduced. However, most women began taking folic acid supplements when they knew that they were pregnant. This is too late for the protection of the embryonic neural tube. In a post-program survey of the women who reported folic acid supplementation, less than a quarter of the women began taking supplements prior to pregnancy, indicating that the remaining three quarters of the fetuses remained unprotected during the time of neural tube formation. Therefore, staple food fortification with folic acid should be considered as a priority in the prevention of NTDs. PMID:26261765

    Defect prevention is the most vital but habitually neglected facet of software quality assurance in any project. If functional at all stages of software development, it can condense the time, overheads and wherewithal entailed to engineer a high quality product. The key challenge of an IT industry is to engineer a software product with minimum post deployment defects. This effort is an analysis based on data obtained for five selected projects from leading software companies of varying software production competence. The main aim of this paper is to provide information on various methods and practices supporting defect detection and prevention leading to thriving software generation. The defect prevention technique unearths 99% of defects. Inspection is found to be an essential technique in generating ideal software generation in factories through enhanced methodologies of abetted and unaided inspection schedules.

    Full Text Available This study was undertaken in Gaza, Palestine, in a cohort of babies born in 2011. Hair samples of newborns were analyzed for metal load by DRC-ICP-MS. We report specific level of contamination by teratogen/toxicants metals of newborn babies, environmentally unexposed, according to their phenotypes at birth: normal full term babies, birth defects or developmentally premature. The occurrence of birth defects was previously shown to be correlated in this cohort to documented exposure of parents to weapons containing metal contaminants, during attacks in 2009. We detect, in significantly higher amounts than in normal babies, different specific teratogen or toxicant elements, known weapons’ components, characteristic for each of birth defect or premature babies. This is the first attempt to our knowledge to directly link a phenotype at birth with the in utero presence of specific teratogen and/or toxicant metals in a cohort with known episodes of acute exposure of parents to environmental contamination by these same metals, in this case delivered by weaponry The babies were conceived 20–25 months after the major known parental exposure; the specific link of newborn phenotypes to war-remnant metal contaminants, suggests that mothers’ contamination persists in time, and that the exposure may have a long term effect.

    Objective To understand the incidence of birth defects in hospitals in Haidian District during recent years so as to provide management clue for supervision in the future. Methods From October 1 of 2006 to September 30 of 2010, fetus and newborns between 13 gestational weeks and 7d after delivery were supervised for birth defects in hospitals of Haidian district, and the supervision results were analyzed in terms of rate and cis position. Results There were 3 776 defected cases including 2 861 cases in perinatal period ( the incidence rate of birth defects in perinatal period was 17. 98‰ ) and 906 cases induced to abortion in second trimester. In floating population the incidence rate of birth defects showed a rising trend in perinatal period during these years( x2 =52. 250, P = 0. 000 ). The first five highest rates of birth defects were congenital heart disease, deformity of external ear, multi finger ( toe ), merged finger ( toe ) and hypospadias in order. The trend of neural tube defects rate was stable and the incidence of cleft lip dropped obviously. But the incidence of Trisomy 21 rose gradually, and there was no significant difference (x2 =6. 906, P =0. 075 ). Conclusion The incidence rate of birth defects is 17. 98‰ in hospitals of Haidian district, and the trend of birth defects rate is rising during 2006-2010 year especially in floating population.

    2014-04-01

    Defect turbulence described by the one-dimensional complex Ginzburg-Landau equation is investigated and analyzed via a birth-death process of the local structures composed of defects, holes, and modulated amplitude waves (MAWs). All the number statistics of each local structure, in its stationary state, are subjected to Poisson statistics. In addition, the probability density functions of interarrival times of defects, lifetimes of holes, and MAWs show the existence of long-memory and some characteristic time scales caused by zigzag motions of oscillating traveling holes. The corresponding stochastic process for these observations is fully described by a non-Markovian master equation.

  8. Drugs to block cytokine signaling for the prevention and treatment of inflammation induced preterm birth

    Directory of Open Access Journals (Sweden)

    Pearl Y Ng

    2015-04-01

    Full Text Available Preterm birth (PTB at less than 37 weeks of gestation is the leading cause of neonatal morbidity and mortality. Intrauterine infection (IUI due to microbial invasion of the amniotic cavity is the leading cause of early PTB (<32 weeks. Commensal genital tract Ureaplasma and Mycoplasma species, as well as Gram-positive and Gram-negative bacteria, have been associated with IUI-induced PTB. Bacterial activation of toll-like receptors (TLRs and other pattern recognition receptors initiates a cascade of inflammatory signaling via the NF-κB and p38 MAPK signaling pathways, prematurely activating parturition. Antenatal antibiotic treatment has had limited success in preventing PTB or fetal inflammation. Administration of anti-inflammatory drugs with antibiotics could be a viable therapeutic option to prevent PTB and fetal complications in women at risk of IUI and inflammation. In this mini-review we will discuss the potential for anti-inflammatory drugs in obstetric care, focusing on the class of drugs termed ‘cytokine suppressive anti-inflammatory drugs’ or CSAIDs. These inhibitors work by specifically targeting the NF-κB and p38 MAPK inflammatory signaling pathways. Several CSAIDs are discussed, together with clinical and toxicological considerations associated with the administration of anti-inflammatory agents in pregnancy.

  9. Etiology, pathogenesis and prevention of neural tube defects.

    Science.gov (United States)

    Padmanabhan, Rengasamy

    2006-06-01

    Spina bifida, anencephaly, and encephalocele are commonly grouped together and termed neural tube defects (NTD). Failure of closure of the neural tube during development results in anencephaly or spina bifida aperta but encephaloceles are possibly post-closure defects. NTD are associated with a number of other central nervous system (CNS) and non-neural malformations. Racial, geographic and seasonal variations seem to affect their incidence. Etiology of NTD is unknown. Most of the non-syndromic NTD are of multifactorial origin. Recent in vitro and in vivo studies have highlighted the molecular mechanisms of neurulation in vertebrates but the morphologic development of human neural tube is poorly understood. A multisite closure theory, extrapolated directly from mouse experiments highlighted the clinical relevance of closure mechanisms to human NTD. Animal models, such as circle tail, curly tail, loop tail, shrm and numerous knockouts provide some insight into the mechanisms of NTD. Also available in the literature are a plethora of chemically induced preclosure and a few post-closure models of NTD, which highlight the fact that CNS malformations are of hetergeneitic nature. No Mendelian pattern of inheritance has been reported. Association with single gene defects, enhanced recurrence risk among siblings, and a higher frequency in twins than in singletons indicate the presence of a strong genetic contribution to the etiology of NTD. Non-availability of families with a significant number of NTD cases makes research into genetic causation of NTD difficult. Case reports and epidemiologic studies have implicated a number of chemicals, widely differing therapeutic drugs, environmental contaminants, pollutants, infectious agents, and solvents. Maternal hyperthermia, use of valproate by epileptic women during pregnancy, deficiency and excess of certain nutrients and chronic maternal diseases (e.g. diabetes mellitus) are reported to cause a manifold increase in the

    Defect Prevention is the most critical but most neglected component of the software quality assurance in any project. If applied at all stages of software development, it can reduce the time, cost and resources required to engineer a high quality product. Software inspection has proved to be the most effective and efficient technique enabling defect detection and prevention. Inspections carried at all phases of software life cycle have proved to be most beneficial and value added to the attributes of the software. Work is an analysis based on the data collected for three different projects from a leading product based company.

    Full Text Available OBJECTIVE: Congenital anomalies or Birth Defects are a global problem. It is the most common cause of disability in developed and developing countries. This study aims to evaluate the overall prevalence of clinically detectable congenital anomalies in newborns along with the different forms of congenital anomalies and associated risk factors if any over a period of one year. MATERIALS AND METHOD S: I t’s an observational analytical cross sectional type of study. Seven thousand seven hundred and ninety eight babies born during the period from 1 st Nov, 2013 to 31 st Oct, 2014 were analyzed. Details of cases were recorded after parent’s interviews, clinical, radiological and laboratory evaluations. RESULTS: In our study, we have found that out of the total no. of 7798 babies born during the said period, the total number of congenital anomalies found were 53 0.7%. Cleft lip and palate was the most common anomaly followed by clubfoot. System wise, congenital anomaly of the musculoskeletal system was the highest (45.3%. A male preponderance is seen with M:F = 4:3. Maximum number of anomalies was found in the 20 - 25 y rs of age group. Moreover, anomalies were found more in primi gravida. Various risk factors were associated in 9 numbers of cases out of 53. CONCLUSIONS: Prevalence of congenital anomaly was found to be 0.7% and therefore awareness about preventable risk f actors should be created and early prenatal diagnosis and management of anomalies is recommended.

    Full Text Available Nigeria is second in the world for the number of people with HIV and has a high rate of mother-to-child transmission (MTCT. Over 60% of births in Nigeria occur outside of health care facilities, and because of this, Traditional Birth Attendants (TBAs play a significant role in maternal and child health. It is important that TBAs be knowledgeable about HIV prevention. The purpose of this study was to determine the impact of HIV testing and counseling (HTC knowledge on the HIV prevention practices among TBAs in Nigeria. Five hundred TBAs were surveyed. Chi-square and logistic regression were used to assess differences in HIV prevention practices between TBAs with and without HTC knowledge. TBAs with HTC knowledge are significantly more likely to engage in HIV prevention practices than TBAs without HTC. Prevention practices included: wearing gloves during delivery (p < 0.01, sterilization of delivery equipment (p < 0.01, participation in blood safety training (p < 0.01, and disposal of sharps (p < 0.01. As long as a high percent of births occur outside health care facilities in Nigeria, there will be a need for TBAs. Providing TBAs with HTC training increases HIV prevention practices and can be a key to improve maternal and child health.

    2012-02-03

    BACKGROUND\\/AIM: The pathogenesis of visual field loss associated with macular hole surgery is uncertain but a number of explanations have been proposed, the most convincing of which is the effect of peeling of the posterior hyaloid, causing either direct damage to the nerve fibre layer or to its blood supply at the optic nerve head. The purpose of this preliminary prospective study was to determine the incidence of visual field defects following macular hole surgery in cases in which peeling of the posterior hyaloid was confined only to the area of the macula. METHODS: 102 consecutive eyes that had macular hole surgery had preoperative and postoperative visual field examination using a Humphrey\\'s perimeter. A comparison was made between two groups: I, those treated with vitrectomy with complete posterior cortical vitreous peeling; and II, those treated with a vitrectomy with peeling of the posterior hyaloid in the area of the macula but without attempting a complete posterior vitreous detachment. Specifically, no attempt was made to separate the posterior hyaloid from the optic nerve head. Eyes with stage II or III macular holes were operated. Autologous platelet concentrate and non-expansile gas tamponade was used. Patients were postured prone for 1 week. RESULTS: In group I, 22% of patients were found to have visual field defects. In group II, it was possible to separate the posterior hyaloid from the macula without stripping it from the optic nerve head and in these eyes no pattern of postoperative visual field loss emerged. There were no significant vision threatening complications in this group. The difference in the incidence of visual field loss between group I and group II was significant (p=0.02). The anatomical and visual success rates were comparable between both groups. CONCLUSION: The results from this preliminary study suggest that the complication of visual field loss after macular surgery may be reduced if peeling of the posterior hyaloid is

    Neural tube defects (NTDs) such as spina bifida, anencephaly, and encephalocele are serious birth defects of the brain and spine that occur during the first month of pregnancy when the neural tube fails to close completely. Randomized controlled trials and observational studies have shown that adequate daily consumption of folic acid before and during early pregnancy considerably reduces the risk for NTDs. The U.S. Public Health Service recommends that women capable of becoming pregnant consume 400 µg of folic acid daily for NTD prevention. Furthermore, fortification of staple foods (e.g., wheat flour) with folic acid has decreased folate-sensitive NTD prevalence in multiple settings and is a highly cost-effective intervention.

    Full Text Available Abstract Background Although the connection between ascending infection and preterm birth is undisputed, research focused on finding effective treatments has been disappointing. However evidence that eradication of Candida in pregnancy may reduce the risk of preterm birth is emerging. We conducted a pilot study to assess the feasibility of conducting a large randomized controlled trial to determine whether treatment of asymptomatic candidiasis in early pregnancy reduces the incidence of preterm birth. Methods We used a prospective, randomized, open-label, blinded-endpoint (PROBE study design. Pregnant women presenting at Candida were randomized to 6-days of clotrimazole vaginal pessaries (100mg or usual care (screening result is not revealed, no treatment. The primary outcomes were the rate of asymptomatic vaginal candidiasis, participation and follow-up. The proposed primary trial outcome of spontaneous preterm birth Results Of 779 women approached, 500 (64% participated in candidiasis screening, and 98 (19.6% had asymptomatic vaginal candidiasis and were randomized to clotrimazole or usual care. Women were not inconvenienced by participation in the study, laboratory testing and medication dispensing were problem-free, and the follow-up rate was 99%. There was a tendency towards a reduction in spontaneous preterm birth among women with asymptomatic candidiasis who were treated with clotrimazole RR = 0.33, 95%CI 0.04-3.03.

    Objective: To explore the possibility of repairing long segmental bone defects and preventing infection with cefazolin loaded bone matrix gelatin (C-BMG). Methods: C-BMG was made from putting cefazolin into BMG by vacuum absorption and lyophilization techniques. The sustaining period of effective drug concentration in vitro and in vivo was detected. The time of inhibiting bacteria, and the drug concentration in local tissues ( bone and muscle) and plasma after implantation of C-BMG were examined by high performance liquid chromatography.Results: The effective inhibition time to staphylococcus aureus of C-BMG was 22 days in vitro; while 14 days in vivo. The cefazolin concentration in local tissues was higher in early stage, and later it kept a stable and low drug release. C-BMG showed an excellent ability to repair segmental long bone defects.Conclusions: C-BMG can gradually release cefazolin with effective drug concentration and has excellent ability to repair segmental bone defects. It can be used to repair segmental long bone defects and prevent infection after operation.

    Preterm birth is the main cause of neonatal morbidity and mortality. This review provides an overview of antepartum and intrapartum management of threatened preterm birth. The most effective method to identify women at high risk of delivering within seven days is the combination of cervical length and fetal fibronectin test. Antenatal corticosteroids administered for 48 h improve neonatal outcome. Although tocolysis has been shown to prolong pregnancy, there is no evidence that tocolytic therapy improves neonatal outcomes. Intrapartum administration of magnesium sulfate improves neurologic outcomes, such as cerebral palsy and gross motor function. In women with preterm premature rupture of membranes, prophylactic antibiotic treatment with erythromycin improves short-term neonatal outcomes, but proof of long-term benefit is lacking. In threatened preterm birth with intact membranes, prophylactic antibiotic treatment is thought to be harmful. Critical appraisal of the long-term benefits and harms of all these treatments questions their use. PMID:26875954

    Full Text Available Abstract Background Preterm birth is the principal factor contributing to adverse outcomes in multiple pregnancies. Randomized controlled trials of progestogens to prevent preterm birth in twin pregnancies have shown no clear benefits. However, individual studies have not had sufficient power to evaluate potential benefits in women at particular high risk of early delivery (for example, women with a previous preterm birth or short cervix or to determine adverse effects for rare outcomes such as intrauterine death. Methods/design We propose an individual participant data meta-analysis of high quality randomized, double-blind, placebo-controlled trials of progestogen treatment in women with a twin pregnancy. The primary outcome will be adverse perinatal outcome (a composite measure of perinatal mortality and significant neonatal morbidity. Missing data will be imputed within each original study, before data of the individual studies are pooled. The effects of 17-hydroxyprogesterone caproate or vaginal progesterone treatment in women with twin pregnancies will be estimated by means of a random effects log-binomial model. Analyses will be adjusted for variables used in stratified randomization as appropriate. Pre-specified subgroup analysis will be performed to explore the effect of progestogen treatment in high-risk groups. Discussion Combining individual patient data from different randomized trials has potential to provide valuable, clinically useful information regarding the benefits and potential harms of progestogens in women with twin pregnancy overall and in relevant subgroups.

    Although outcomes of neonatal cardiac surgery have dramatically improved in the last two decades, low body weight still constitutes an important risk factor for morbidity and mortality. In particular, cardiac surgery in neonates with very low birth weight (≤1.5 kg) is carried out with greater risk because most organ systems are immature. We report here on a successful case of early one-stage total repair of coarctation of the aorta and a ventricular septal defect in a 1,480 gram neonate.

    Full Text Available Abstract Background Prevention of preterm birth remains one of the most important challenges in maternity care. We propose a randomised trial with: a simple Candida testing protocol that can be easily incorporated into usual antenatal care; a simple, well accepted, treatment intervention; and assessment of outcomes from validated, routinely-collected, computerised databases. Methods/Design Using a prospective, randomised, open-label, blinded-endpoint (PROBE study design, we aim to evaluate whether treating women with asymptomatic vaginal candidiasis early in pregnancy is effective in preventing spontaneous preterm birth. Pregnant women presenting for antenatal care The study protocol draws on the usual antenatal care schedule, has been pilot-tested and the intervention involves only a minor modification of current practice. Women who agree to participate will self-collect a vaginal swab and those who are culture positive for Candida will be randomised (central, telephone to open-label treatment or usual care (screening result is not revealed, no treatment, routine antenatal care. Outcomes will be obtained from population databases. A sample size of 3,208 women with Candida colonisation (1,604 per arm is required to detect a 40% reduction in the spontaneous preterm birth rate among women with asymptomatic candidiasis from 5.0% in the control group to 3.0% in women treated with clotrimazole (significance 0.05, power 0.8. Analyses will be by intention to treat. Discussion For our hypothesis, a placebo-controlled trial had major disadvantages: a placebo arm would not represent current clinical practice; knowledge of vaginal colonisation with Candida may change participants' behaviour; and a placebo with an alcohol preservative may have an independent affect on vaginal flora. These disadvantages can be overcome by the PROBE study design. This trial will provide definitive evidence on whether screening for and treating asymptomatic candidiasis in

    Epidemiologic studies of the neural tube defects (NTDs), anencephalus and spina bifida, have for the most part been based on single sources of case ascertainment in past studies. The present investigation attempts total ascertainment of NTD cases in the newborn population of Los Angeles County residents for the period 1966 to 1972. Design of the study, sources of data, and estimates of prevalence rates based on single and multiple sources of case ascertainment are here discussed. Anencephalus cases totaled 448, spina bifida 442, and encephalocele 72, giving prevalence rates of 0.52, 0.51, and 0.08 per 1000 total births, respectively, for these neural tube defects - rates considered to be low. The Los Angeles County prevalence rates are compared with those of other recent North American studies and support is provided for earlier suggestions of low rates on the West Coast.

  10. Intraurethral knot in a very-low-birth-weight infant: radiological recognition, surgical management and prevention

    International Nuclear Information System (INIS)

    We report a case where a knot developed in a urinary catheter and became lodged within the urethra of a very-low-birth-weight (VLBW) preterm infant. The catheter was removed with the assistance of a urologist. We recommend using caution when placing urinary catheters in VLBW infants and question the appropriateness of feeding tubes as catheters. Recognition on radiographs of malpositioned bladder catheters is vital to the care of these patients. All staff involved in the insertion, maintenance or removal of these catheters should be suitably trained to minimize the risk of knots and related complications. (orig.)

    Sever, L.E.

    1982-01-01

    Epidemiologic characteristics of neural tube defect (NTD) births occurring in Los Angeles County, California, residents during the period 1966-1972 are presented. The prevalence at birth was 0.52/1000 births for anencephalus, 0.51/1000 for spina bifida, and 0.08/1000 for encephalocele, rates considered to be low for a predominantly white population. We hypothesized that environmental (nongenetic) factors are of less etiologic importance in a low-prevalence population than in areas or time periods with high prevalence. We tested that hypothesis by examining epidemiologic characteristics of NTDs in Los Angeles County and comparing them with high-prevalence populations. The data did not support a major etiologic role for environmental factors: (1) no significant differences between rates by month of birth or conception; (2) no significant association with maternal age or parity for anencephalus; for spina bifida a significant maternal age effect (P < 0.01) and for encephalocele a parity effect (P < 0.02); and (3) no significant relationship with father's occupational class for either anencephalus or encephalocele but a marginally significant (P < 0.05) inverse association for spina bifida when a statistic based on ordinal relationships was used. Findings supporting the importance of genetic factors in etiology included: (1) a high percentage of males; (2) a higher twin concordance rate than in high-prevalence populations; and (3) an anencephalus rate among blacks comparable with rates for blacks in other United States populations. Our findings in conjunction with those from other areas and times of low prevalence suggest environmental factors play a relatively insignificant role in the etiology of NTDs in such populations.

  15. Prevention of alcohol abuse-related birth effects--II. Targeting and pricing.

    Science.gov (United States)

    Abel, E L

    1998-01-01

    Current public health measures to reduce the occurrence of fetal alcohol abuse syndrome (FAAS) and alcohol abuse-related birth effects (AARBEs) have been ineffective, because they target alcohol consumption, rather than alcohol abuse. The present discussion contends that the most effective public health strategy for reducing FAAS and AARBEs is a combination of more specific public health messages that target alcohol abuse, coupled with higher taxes on alcohol beverages. Although alcohol consumption by alcohol abusers has been thought to be inelastic to price changes, recent studies have found that both heavy drinking and binge drinking are sensitive to alcohol price changes, and price elasticities are relatively high for heavy drinkers who are aware of the consequences of their drinking. Although price increases may have a disproportionate impact on lower socioeconomic groups, this article concludes that they are justifiable from both a utilitarian and a categorical imperative perspective.

    Iraq is suffering from depleted uranium (DU) pollution in many regions and the effects of this may harm public health through poisoning and increased incidence of various cancers and birth defects. DU is a known carcinogenic agent. About 1200 tonnes of ammunition were dropped on Iraq during the Gulf Wars of 1991 and 2003. As a result, contamination occurred in more than 350 sites in Iraq. Currently, Iraqis are facing about 140,000 cases of cancer, with 7000 to 8000 new ones registered each year. In Baghdad cancer incidences per 100,000 population have increased, just as they have also increased in Basra. The overall incidence of breast and lung cancer, Leukaemia and Lymphoma, has doubled even tripled. The situation in Mosul city is similar to other regions. Before the Gulf Wars Mosul had a higher rate of cancer, but the rate of cancer has further increased since the Gulf Wars. PMID:23729095

    In Norway, external doses of radiation resulting from fallout from the Chernobyl nuclear accident were estimated from detailed measurements, including soil deposition patterns. Internal doses were estimated from measurements of radioactive cesium in meat and milk supplies. The doses were calculated as average monthly doses for each of 454 municipalities during 36 consecutive months after the accident in spring 1986. Prospectively collected data on all newborns listed in the Medical Birth Registry of Norway who were conceived in the period May 1983-April 1989 were used to assess possible dose-response relations between estimated external and food-based exposures and congenital malformations and some other conditions. A positive association was observed between total radiation dose (external plus food-based) and hydrocephaly, while a negative association was observed for Down's syndrome. However, an important conclusion of the study was that no associations were found for conditions previously reported to be associated with radiation, i.e., small head circumference, congenital cataracts, anencephaly, spina bifida, and low birth weight. Potential sources of bias, including exposure misclassification and incomplete ascertainment of cases, are discussed.

    Full Text Available Down syndrome (DS leads to complex phenotypes and is the main genetic cause of birth defects and heart diseases. The Ts65Dn DS mouse model is trisomic for the distal part of mouse chromosome 16 and displays similar features with post-natal lethality and cardiovascular defects. In order to better understand these defects, we defined electrocardiogram (ECG with a precordial set-up, and we found conduction defects and modifications in wave shape, amplitudes, and durations in Ts65Dn mice. By using a genetic approach consisting of crossing Ts65Dn mice with Ms5Yah mice monosomic for the App-Runx1 genetic interval, we showed that the Ts65Dn viability and ECG were improved by this reduction of gene copy number. Whole-genome expression studies confirmed gene dosage effect in Ts65Dn, Ms5Yah, and Ts65Dn/Ms5Yah hearts and showed an overall perturbation of pathways connected to post-natal lethality (Coq7, Dyrk1a, F5, Gabpa, Hmgn1, Pde10a, Morc3, Slc5a3, and Vwf and heart function (Tfb1m, Adam19, Slc8a1/Ncx1, and Rcan1. In addition cardiac connexins (Cx40, Cx43 and sodium channel sub-units (Scn5a, Scn1b, Scn10a were found down-regulated in Ts65Dn atria with additional down-regulation of Cx40 in Ts65Dn ventricles and were likely contributing to conduction defects. All these data pinpoint new cardiac phenotypes in the Ts65Dn, mimicking aspects of human DS features and pathways altered in the mouse model. In addition they highlight the role of the App-Runx1 interval, including Sod1 and Tiam1, in the induction of post-natal lethality and of the cardiac conduction defects in Ts65Dn. These results might lead to new therapeutic strategies to improve the care of DS people.

    Altered development of the human cerebral cortex can cause severe malformations with often intractable focal epileptic seizures and may participate in common pathologies, notably epilepsy. This raises important conceptual and therapeutic issues. Two missense mutations in the sushi repeat-containing protein SRPX2 had been previously identified in epileptic disorders with or without structural developmental alteration of the speech cortex. In the present study, we aimed to decipher the precise developmental role of SRPX2, to have a better knowledge on the consequences of its mutations, and to start addressing therapeutic issues through the design of an appropriate animal model. Using an in utero Srpx2 silencing approach, we show that SRPX2 influences neuronal migration in the developing rat cerebral cortex. Wild-type, but not the mutant human SRPX2 proteins, rescued the neuronal migration phenotype caused by Srpx2 silencing in utero, and increased alpha-tubulin acetylation. Following in utero Srpx2 silencing, spontaneous epileptiform activity was recorded post-natally. The neuronal migration defects and the post-natal epileptic consequences were prevented early in embryos by maternal administration of tubulin deacetylase inhibitor tubacin. Hence epileptiform manifestations of developmental origin could be prevented in utero, using a transient and drug-based therapeutic protocol. PMID:23831613

    In 2008, planned folic acid fortification for the prevention of Neural Tube Defects (NTD) was postponed. Concurrently, the economic recession may have affected dietary folic acid intake, placing increased emphasis on supplement use. This study examined folic acid supplement use in 2009. A cross-sectional survey of 300 ante-natal women was undertaken to assess folic acid knowledge and use. Associations between demographic, obstetric variables and folic acid knowledge and use were examined. A majority, 284\\/297 (96%), had heard of folic acid, and 178\\/297 (60%) knew that it could prevent NTD. Most, 270\\/297 (91%) had taken it during their pregnancy, but only 107\\/297 (36%) had used it periconceptionally. Being older, married, planned pregnancy and better socioeconomic status were associated with periconceptional use. Periconceptional folic acid use in 2009 was very low, little changed from economic status were associated with periconceptional use. Periconceptional folic acid use in 2009 was very low, little changed from earlier years. Continuous promotion efforts are necessary. Close monitoring of folic acid intake and NTD rates is essential, particularly in the absence of fortification.

  14. BQ-123 prevents LPS-induced preterm birth in mice via the induction of uterine and placental IL-10

    International Nuclear Information System (INIS)

    Preterm birth (PTB), defined as any delivery occurring prior to the completion of 37 weeks' gestation, currently accounts for 11–12% of all births in the United States. Maternal genito-urinary infections account for up to 40% of all PTBS and induce a pro-inflammatory state in the host. The potent vasoconstrictor Endothelin-1 (ET-1) is known to be upregulated in the setting of infection, and elicits its effect by binding to the ETA receptor. We have previously shown that antagonism of the ETA receptor with BQ-123 is capable of preventing LPS-induced PTB in mice. We hypothesize that the administration of BQ-123 post LPS exposure will dismantle a positive feedback loop observed with pro-inflammatory cytokines upstream of ET-1. On GD 15.5, pregnant C57BL/6 mice were injected with PBS, LPS, BQ-123, or LPS + BQ-123. Changes at both the level of transcription and translation were observed in uterus and placenta in the ET-1 axis and in pro- and anti-inflammatory cytokines over the course of 12 h. We discovered that BQ-123, when administered 10 h post LPS, is capable of increasing production of uterine and placental Interleukin-10, causing a shift away from the pro-inflammatory state. We also observed that antagonism of the ETA receptor decreased IL-1β and TNFα in the placenta while also decreasing transcription of ET-1 in the uterus. Our results reinforce the role of ET-1 at the maternal fetal interface and highlight the potential benefit of ETA receptor blockade via the suppression of ET-1, and induction of a Th2 cytokine dominant state. - Highlights: • The pro-inflammatory response to LPS in the uterus and placenta is ET-1 dependent. • ETA blockade triggers up-regulation of IL-10 in uterus and placenta. • A positive feedback loop drives ET-1 expression in gestational tissue

    The purpose of this study was to evaluate the efficacy of omega-3 supplementation for the prevention of recurrent preterm birth (PTB) in asymptomatic singleton gestations with previous PTB. We searched fish oil, long chain polyunsaturated fatty acids, pregnancy, and omega-3 in MEDLINE, OVID, Scopus, ClinicalTrials.gov, the PROSPERO International Prospective Register of Systematic Reviews, EMBASE, and the Cochrane Central Register of Controlled Trials from inception of each database to December 2014 with no limit for language. In addition the reference lists of all identified articles were examined to identify studies that were not captured by electronic searches. We performed a metaanalysis of randomized controlled trials of asymptomatic singleton gestations with previous PTB who were assigned randomly to prophylactic omega-3 supplementation vs control (either placebo or no treatment). The primary outcome was predefined as PTB at trials that included 1080 women were analyzed. The mean gestational age at randomization was approximately 134 days in both groups (mean difference, 0.01 days; 95% CI, -0.13 to 0.14). Women who received omega-3 had similar rates of PTB at <37 weeks of gestation (34.5% vs 39.8%; RR, 0.81; 95% CI, 0.59-1.12) and PTB at <34 weeks of gestation (12.0% vs 15.4%; RR, 0.62; 95% CI, 0.26-1.46) compared with control subjects. The omega-3 groups had a statistically significantly longer latency (mean difference, 2.10 days; 95% CI, 1.98-2.22) and higher birthweight (mean difference, 102.52 g; 95% CI, 20.09-184.95) compared with control subjects; the other secondary outcomes (which included gestational age at delivery, spontaneous PTB at <37 and 34 weeks of gestation, admission to the intensive care unit, intraventricular hemorrhage, necrotizing enterocolitis, sepsis, and perinatal death) were similar. Omega-3 supplementation during pregnancy does not prevent recurrent PTB in asymptomatic singleton gestations with previous PTB. The benefits in longer

    This article is part of the EuroSTEC project, which aims at developing tissue engineering-based treatments for structural disorders present at birth. EuroSTEC is positioned at the intersection of three areas with their own ethical issues: (1) regenerative medicine, (2) research with pregnant women and fetuses, and (3) research with neonates. Because of the overlap of these three areas in this project, we can expect to be confronted with new ethical challenges. To be able to respond adequately and timely to current and possible future ethical issues, a prospective and anticipatory ethical analysis is essential. To obtain a first survey of ethical issues that might arise during the different phases of the project, the Delphi method was used. The professionals directly involved in the EuroSTEC project were questioned about their views on possible ethical issues. The first round yielded 27 ethical issues, which the respondents were asked to prioritize in the second round. For the fundamental research phase, issues deemed most important were privacy and informed consent of the tissue donor. For the animal experimentation phase, three issues were mentioned (in order of decreasing priority): the suffering of animals, the use of animals as means to an end, and the limited adequacy of the animal models. Issues that were deemed most important during the clinical (trial) phase pertained to the problem of weighing risks and benefits for the fetus/child and the pregnant woman. PMID:20163208

    Melatonin, an endogenous neurohormone secreted by the pineal gland, has a variety of physiological functions and neuroprotective effects. However, its protective role on the neural tube defects (NTDs) was not very clear. The aim of this study was to investigate the effects of melatonin on the incidence of NTDs (including anencephaly, encephalocele, and spina bifida) of offspring from diabetic pregnant mice as well as its underlying mechanisms. Pregnant mice were given 10 mg/kg melatonin by daily i.p. injection from embryonic day (E) 0.5 until being killed on E11.5. Here, we showed that melatonin decreased the NTDs (especially exencephaly) rate of embryos exposed to maternal diabetes. Melatonin stimulated proliferation of neural stem cells (NSCs) under hyperglycemic condition through the extracellular regulated protein kinases (ERK) pathway. Furthermore, as a direct free radical scavenger, melatonin decreased apoptosis of NSCs exposed to hyperglycemia. In the light of these findings, it suggests that melatonin supplementation may play an important role in the prevention of neural malformations in diabetic pregnancy. PMID:26475080

    The replication and segregation of multi-copy mitochondrial DNA (mtDNA) are not under strict control of the nuclear DNA. Within-cell selection may thus favour variants with an intracellular selective advantage but a detrimental effect on cell fitness. High relatedness among the mtDNA variants of an individual is predicted to disfavour such deleterious selfish genetic elements, but experimental evidence for this hypothesis is scarce. We studied the effect of mtDNA relatedness on the opportunities for suppressive mtDNA variants in the fungus Neurospora carrying the mitochondrial mutator plasmid pKALILO. During growth, this plasmid integrates into the mitochondrial genome, generating suppressive mtDNA variants. These mtDNA variants gradually replace the wild-type mtDNA, ultimately culminating in growth arrest and death. We show that regular sequestration of mtDNA variation is required for effective selection against suppressive mtDNA variants. First, bottlenecks in the number of mtDNA copies from which a 'Kalilo' culture started significantly increased the maximum lifespan and variation in lifespan among cultures. Second, restrictions to somatic fusion among fungal individuals, either by using anastomosis-deficient mutants or by generating allotype diversity, prevented the accumulation of suppressive mtDNA variants. We discuss the implications of these results for the somatic accumulation of mitochondrial defects during ageing. PMID:24864316

    The previously reported hypothesis of an etiologic association of heart and blood abnormalities was further investigated in a population based study of congenital cardiovascular malformations (CCVM). Three presumed genetic risk factors (CCVM in parents and siblings, heritable blood disorders and maternal mitral valve prolapse) were found to occur significantly more often in cases than in normal controls, irrespective of the presence in the proband of chromosomal or Mendelian lesions. This suggests a specific etiologic origin of the CCVM; the excess of maternal risk components raises the possibility of X-linked inheritance. Observed constellations of heart, blood, and connective tissue disorders within members of a nuclear family may indicate variability of phenotypic expression of a similar biosynthetic defect. A schematic model of abnormal cardiogenesis is presented which supports the above observations with the results of biochemical studies on endothelium, platelets and collagen disorders. It is suggested that teratogenesis results from subtle interactions of genetic sequelae with extrinsic metabolic and xenobiotic effects. This conclusion harmonizes with those derived from experimental animal studies. PMID:2937867

    Preterm birth (PTB), defined as any delivery occurring prior to the completion of 37 weeks' gestation, currently accounts for 11–12% of all births in the United States. Maternal genito-urinary infections account for up to 40% of all PTBS and induce a pro-inflammatory state in the host. The potent vasoconstrictor Endothelin-1 (ET-1) is known to be upregulated in the setting of infection, and elicits its effect by binding to the ET{sub A} receptor. We have previously shown that antagonism of the ET{sub A} receptor with BQ-123 is capable of preventing LPS-induced PTB in mice. We hypothesize that the administration of BQ-123 post LPS exposure will dismantle a positive feedback loop observed with pro-inflammatory cytokines upstream of ET-1. On GD 15.5, pregnant C57BL/6 mice were injected with PBS, LPS, BQ-123, or LPS + BQ-123. Changes at both the level of transcription and translation were observed in uterus and placenta in the ET-1 axis and in pro- and anti-inflammatory cytokines over the course of 12 h. We discovered that BQ-123, when administered 10 h post LPS, is capable of increasing production of uterine and placental Interleukin-10, causing a shift away from the pro-inflammatory state. We also observed that antagonism of the ET{sub A} receptor decreased IL-1β and TNFα in the placenta while also decreasing transcription of ET-1 in the uterus. Our results reinforce the role of ET-1 at the maternal fetal interface and highlight the potential benefit of ET{sub A} receptor blockade via the suppression of ET-1, and induction of a Th2 cytokine dominant state. - Highlights: • The pro-inflammatory response to LPS in the uterus and placenta is ET-1 dependent. • ET{sub A} blockade triggers up-regulation of IL-10 in uterus and placenta. • A positive feedback loop drives ET-1 expression in gestational tissue.

    Full Text Available In developing countries, it would be advisable to give priority to human immunodeficiency virus (HIV prevention strategies, because of the high mortality caused by the rapid spread of the pandemic. Furthermore, HIV prevention could contribute to the mitigation of tuberculosis (TB propagation, which is tightly correlated to acquired immune deficiency syndrome (AIDS. As demonstrated, male circumcision (MC confers protection against HIV and sexually transmitted diseases (STD. The suggested strategy considers the neonatal MC advantageous, since it is safer, feasible, culturally more acceptable and less costly than adult MC. This approach is based on the assumption that, if newborn males are circumcised, within the next 15-20 years the sexually active population will be almost entirely circumcised and, consequently, the HIV transmission will be reduced. The employment of retrained traditional birth attendants is considered in order to implement the MC after the child birth and to facilitate its acceptance in those contexts where it is not traditionally performed.

    The categories of low birth weigth infants, social vs. racial factors, factors increasing the risk of low birth weight, prevention of low birth weight, social factors in the development of low birth weight children, the influence of social factors vs. other variables, and implications for management are reviewed. In 1948 the World Health Assembly designated children who were born weighing 2500 g or less as "immature" and further stated that a liveborn infant with a period of gestation of less than 37 weeks or specified as "premature" may be considered as the equivalent of an immature event. In 1961 it was recommended that babies weighing 2500 g or less should no longer be referred to as being "premature" and that the concept of "prematurity" in the definition should give way to that of "low birth weight." Intrauterine growth curves for liveborn males and females were devised from data on birth weight and gestational age. Infants born prior to 37 completed weeks of gestation whose weight lies between the 10th and 90th percentiles on such curves may be called preterm with a weight appropriate for gestational age (AGA), whereas infants born after any length of gestation whose birth weight is at or below the 10th percentile may be named hypotrophic or small for gestational age (SGA). On a worldwide scale it has been estimated that about 22 million low birth weight babies, representing roughly 1/6 of all births, are born alive each day. Only about 1 million of them (mostly preterm) are born in developed countries; of the 21 million born in developing areas, roughly 16 million are SGA full-term and not preterm babies. Socioeconomic status appears as 1 of the most important dterminants of the ultimate level of brain function in children of low birth weight, and this is true with respect to neurologic, psychologic, and educational outcome. Social class also has an indirect effect through birth weight, frequency of perinatal brain injury, and other biological variables as

    In this contribution, we study using first principles the co-adsorption and catalytic behaviors of CO and O2 on a single gold atom deposited at defective magnesium oxide surfaces. Using cluster models and point charge embedding within a density functional theory framework, we simulate the CO oxidation reaction for Au1 on differently charged oxygen vacancies of MgO(001) to rationalize its experimentally observed lack of catalytic activity. Our results show that: (1) co-adsorption is weakly supported at F(0) and F(2+) defects but not at F(1+) sites, (2) electron redistribution from the F(0) vacancy via the Au1 cluster to the adsorbed molecular oxygen weakens the O2 bond, as required for a sustainable catalytic cycle, (3) a metastable carbonate intermediate can form on defects of the F(0) type, (4) only a small activation barrier exists for the highly favorable dissociation of CO2 from F(0), and (5) the moderate adsorption energy of the gold atom on the F(0) defect cannot prevent insertion of molecular oxygen inside the defect. Due to the lack of protection of the color centers, the surface becomes invariably repaired by the surrounding oxygen and the catalytic cycle is irreversibly broken in the first oxidation step.

  18. Can the season of birth risk factor for schizophrenia be prevented by bright light treatment for the second trimester mother around the winter solstice?

    Schwartz, Paul J

    2014-12-01

    The season of birth risk factor for schizophrenia exerts a pervasive effect on the global population, particularly at northerly latitudes. The winter infection hypothesis and the low vitamin D hypothesis are both compelling but lack conclusive clinical data. The present work develops a maternal-fetal chronobiological hypothesis for this season of birth risk factor and its prevention by maternal bright light treatment. Around the winter solstice, due to decreased sunlight, the chronobiological apparatus of the at-risk second trimester mother is characterized by a reduced amplitude circadian pacemaker, and a reduced maximum of her nocturnal plasma melatonin concentrations (MTmax) and an increased minimum of her nocturnal core body temperatures (Tmin)--both of which exert adverse effects on the fetal hippocampus and dorsal striatum. The consequences for the fetus include reduced volume and increased excitability of the hippocampus, ventral striatal dysfunction, increased presynaptic nigrostriatal dopamine transmission, and increased propensity for pathological nigrostriatal neuronal phasic firing. Thus, the maternal-fetal chronobiological hypothesis fully accounts for the fetal precursors of the major pathognomonic abnormalities in adults with schizophrenia. Bright light treatment for the second trimester mother around the winter solstice, by increasing maternal circadian amplitude, could possibly prevent the fetal hippocampal and striatal abnormalities and eliminate the season of birth risk factor for schizophrenia.

    We have been developing an amorphous selenium (a-Se) avalanche multiplication photoconductive film, named HARP (high-gain avalanche rushing amorphous photoconductor), for the purpose of making a high-sensitivity video camera useful for broadcasting, x-ray medical diagnosis, etc. The HARP film used for the red channel in a colour camera is doped with tellurium (Te) to improve its red-light sensitivity. However, doping a-Se with Te generates impurity levels that trap electrons, and the built-in-field formed by these trapped electrons causes image defects. We devised a heat treatment to prevent the occurrence of these defects. We suppose that the thermal energy of the heat treatment releases the originally trapped electrons, and that the energy makes it difficult for moving electrons to be trapped during operation.

    Full Text Available Abstract Background Periconceptional use of vitamin supplements containing folic acid reduces the risk of a neural tube defect (NTD. In November 1998, food fortification with folic acid was mandated in Canada, as a public health strategy to increase the folic acid intake of all women of childbearing age. We undertook a comprehensive population based study in Newfoundland to assess the benefits and possible adverse effects of this intervention. Methods This study was carried out in women aged 19–44 years and in seniors from November 1997 to March 1998, and from November 2000 to March 2001. The evaluation was comprised of four components: I Determination of rates of NTDs; II Dietary assessment; III Blood analysis; IV Assessment of knowledge and use of folic acid supplements. Results The annual rates of NTDs in Newfoundland varied greatly between 1976 and 1997, with a mean rate of 3.40 per 1,000 births. There was no significant change in the average rates between 1991–93 and 1994–97 (relative risk [RR] 1.01, 95% confidence interval [CI] 0.76–1.34. The rates of NTDs fell by 78% (95% CI 65%–86% after the implementation of folic acid fortification, from an average of 4.36 per 1,000 births during 1991–1997 to 0.96 per 1,000 births during 1998–2001 (RR 0.22, 95% CI 0.14–0.35. The average dietary intake of folic acid due to fortification was 70 μg/day in women aged 19–44 years and 74 μg/day in seniors. There were significant increases in serum and RBC folate levels for women and seniors after mandatory fortification. Among seniors, there were no significant changes in indices typical of vitamin B12 deficiencies, and no evidence of improved folate status masking haematological manifestations of vitamin B12 deficiency. The proportion of women aged 19–44 years taking a vitamin supplement containing folic acid increased from 17% to 28%. Conclusions Based on these findings, mandatory food fortification in Canada should continue at the

    Neural tube defects (NTDs), including anencephaly and spina bifida, arise from the failure of neurulation during early embryonic development. Neural tube defects are common birth defects with a heterogenous and multifactorial etiology with interacting genetic and environmental risk factors. Although the mechanisms resulting in failure of neural tube closure are unknown, up to 70% of NTDs can be prevented by maternal folic acid supplementation. However, the metabolic mechanisms underlying the ...

    Full Text Available Abstract Background Azithromycin reduces the severity of illness in patients with inflammatory lung disease such as cystic fibrosis and diffuse panbronchiolitis. Bronchopulmonary dysplasia (BPD is a pulmonary disorder which causes significant morbidity and mortality in premature infants. BPD is pathologically characterized by inflammation, fibrosis and impaired alveolar development. The purpose of this study was to obtain pilot data on the effectiveness and safety of prophylactic azithromycin in reducing the incidence and severity of BPD in an extremely low birth weight (≤ 1000 grams population. Methods Infants ≤ 1000 g birth weight admitted to the University of Kentucky Neonatal Intensive Care Unit (level III, regional referral center from 9/1/02-6/30/03 were eligible for this pilot study. The pilot study was double-blinded, randomized, and placebo-controlled. Infants were randomized to treatment or placebo within 12 hours of beginning mechanical ventilation (IMV and within 72 hours of birth. The treatment group received azithromycin 10 mg/kg/day for 7 days followed by 5 mg/kg/day for the duration of the study. Azithromycin or placebo was continued until the infant no longer required IMV or supplemental oxygen, to a maximum of 6 weeks. Primary endpoints were incidence of BPD as defined by oxygen requirement at 36 weeks gestation, post-natal steroid use, days of IMV, and mortality. Data was analyzed by intention to treat using Chi-square and ANOVA. Results A total of 43 extremely premature infants were enrolled in this pilot study. Mean gestational age and birth weight were similar between groups. Mortality, incidence of BPD, days of IMV, and other morbidities were not significantly different between groups. Post-natal steroid use was significantly less in the treatment group [31% (6/19] vs. placebo group [62% (10/16] (p = 0.05. Duration of mechanical ventilation was significantly less in treatment survivors, with a median of 13 days (1–47

    developed. The main goal of such a policy should be the organization of a functional integrated genetics network, in addition to rational use of resources and enhanced coverage. In order to formalize a national laboratory network, sample shipping and billing mechanisms must be created. Birth defect prevention, education for the medical community and general population, and solid epidemiological data collection are strongly recommended as complementary measures. If such recommendations are implemented, it could be possible to organize a network for management of birth defects in Brazil that is regionalized, hierarchical, functional, and democratic as well.

    Vitamin D receptor (VDR) deficiency (knockout, KO) results in a failure of mice to generate an airway hyper-reactivity (AHR) response on both the Balb/c and C57BL/6 background. The cause of the failed AHR response is the defective population of iNKT cells in the VDR KO mice since wildtype (WT) iNKT cells rescued the AHR response. VDR KO mice had significantly fewer iNKT cells and normal numbers of T cells in the spleen compared to WT mice. In Balb/c VDR KO mice the reduced frequencies of iNKT...

    2015-12-01

    Full Text Available Introduction: There is new emphasis on identifying and treating HIV in the first days of life and also an appreciation that low birth weight (LBW and preterm delivery (PTD frequently accompany HIV-related pregnancy. Even in the absence of HIV, PTD and LBW contribute substantially to neonatal and infant mortality. HIV-exposed and -infected infants with these characteristics have received little attention thus far. As HIV programs expand to meet the 90-90-90 target for ending the HIV pandemic, attention should focus on newborn infants, including those delivered preterm or of LBW. Discussion: In high prevalence settings, infant diagnosis of HIV is usually undertaken after the neonatal period. However, as in utero infection may be diagnosed at birth, earlier initiation of therapy may limit viral replication and prevent early damage. Globally, there is growing awareness that preterm and LBW infants constitute a substantial proportion of births each year. Preterm infants are at high risk for vertical transmission. Feeding difficulties, apnoea of prematurity and vulnerability to sepsis occur commonly. Feeding intolerance, a frequent occurrence, may compromise oral administration of medications. Although there is growing experience with post-exposure prophylaxis for HIV-exposed term newborn infants, there is less experience with preterm and LBW infants. For treatment, there are even fewer options for preterm infants. Only zidovudine has adequate dosing recommendations for treating term and preterm infants and has an intravenous formulation, essential if feeding intolerance occurs. Nevirapine dosing for prevention, but not treatment, is well established for both term and preterm infants.HIV diagnosis at birth is likely to be extremely stressful for new parents, more so if caring for preterm or LBW infants. Programs need to adapt to support the medical and emotional needs of young infants and their parents, where interventions may be lifesaving

    2014-06-01

    Full Text Available Open fractures are at risk of serious infection and, if infected, require several surgical interventions and courses of systemic antibiotics. We investigated a new injectable formulation that simultaneously hardens in vivo to form a porous scaffold for bone repair and delivers antibiotics at high concentrations to the local site of infection. Duration of antimicrobial activity against Staphylococcus aureus was determined using the serial plate transfer test. Ultimate compressive strength and porosity of the material was measured with and without antibiotics. The material was evaluated in vivo in an ovine medial femoral condyle defect model contaminated with S. aureus. Sheep were sacrificed at either 2 or 13 weeks and the defect and surrounding bone assessed using micro-computed tomography and histology. Antimicrobial activity in vitro persisted for 19-21 days. Sheep with antibiotic-free material and bacteria became infected, while those with antibiotic-containing material and bacteria did not. Similarly, new bone growth was seen in uninoculated animals with plain polymer, and in those with antibiotic polymer with bacteria, but not in sheep with plain polymer and bacteria. The antibiotic-impregnated scaffolds were effective in preventing S. aureus infections whilst supporting bone growth and repair. If translated into clinical practice, this approach might reduce the need for systemic antibiotics.

    Somatic cell nuclear transfer has established that the oocyte contains maternal factors with epigenetic reprogramming capacity. Yet the identity and function of these maternal factors during the gamete to embryo transition remains poorly understood. In C. elegans, LSD1/KDM1A enables this transition by removing H3K4me2 and preventing the transgenerational inheritance of transcription patterns. Here we show that loss of maternal LSD1/KDM1A in mice results in embryonic arrest at the 1-2 cell stage, with arrested embryos failing to undergo the maternal-to-zygotic transition. This suggests that LSD1/KDM1A maternal reprogramming is conserved. Moreover, partial loss of maternal LSD1/KDM1A results in striking phenotypes weeks after fertilization; including perinatal lethality and abnormal behavior in surviving adults. These maternal effect hypomorphic phenotypes are associated with alterations in DNA methylation and expression at imprinted genes. These results establish a novel mammalian paradigm where defects in early epigenetic reprogramming can lead to defects that manifest later in development. PMID:26814574

  4. Supplemental vitamin A prevents the acute radiation-induced defect in wound healing

    International Nuclear Information System (INIS)

    Acute radiation injury leads to thymic involution, adrenal enlargement, leukopenia, thrombocytopenia, gastrointestinal ulceration, and impaired wound healing. The authors hypothesized that supplemental vitamin A would mitigate these adverse effects in rats exposed to acute whole-body radiation. To test their hypothesis, dorsal skin incisions and subcutaneous implantation of polyvinyl alcohol sponges were performed in anesthetized Sprague-Dawley rats at varying times following sham radiation or varying doses of whole-body radiation (175-850 rad). In each experiment, the control diet [which contains about 18,000 IU vit. A/kg chow (3 X the NRC RDA for normal rats)] was supplemented with 150,000 IU vit. A/kg diet beginning at, before, or after sham radiation and wounding or radiation and wounding. The supplemental vitamin A prevented the impaired wound healing and lessened the weight loss, leukopenia, thrombocytopenia, thymic involution, adrenal enlargement, decrease in splenic weight, and gastric ulceration of the radiated (750-850 rad) wounded rats. This was true whether the supplemental vitamin A was begun before (2 or 4 days) or after (1-2 hours to 4 days) radiation and wounding; the supplemental vitamin A was more effective when started before or up to 2 days after radiation and wounding. The authors believe that prevention of the impaired wound healing following radiation by supplemental vitamin A is due to its enhancing the early inflammatory reaction to wounding, including increasing the number of monocytes and macrophages at the wound site; possible effect on modulating collagenase activity; effect on epithelial cell (and possible mesenchymal cell) differentiation; stimulation of immune responsiveness; and lessening of the adverse effects of radiation

    Intrauterine growth restriction and preterm birth (PTB) account for a large share of global child mortality, morbidity and developmental loss. Of the numerous risk factors for these conditions, maternal infections have been most consistently identified. Our aim was to study if presumptive antibiotic treatment of pregnant women before any signs of the onset of labor would promote fetal growth and reduce the incidence of PTB or low birthweight (LBW). In a systematic literature search, we identified 14 clinical trials of sufficient quality. Eight trials concluded that there was a positive effect on one or both of the conditions, and others found no such association. The trials reporting an effect were typically conducted in Sub-Saharan Africa (6 trials) and with broadest spectrum antibiotics, whereas data from India (2) suggested no intervention effect and trials in the US (5) or Europe (1) yielded both positive and negative findings. We conclude that appropriately chosen presumptive antimicrobial treatment of pregnant women, targeting infections in the reproductive tract but also other maternal infections such as malaria, other parasitic diseases, skin infections, and periodontitis, can in selected contexts promote fetal growth and reduce the incidence of PTB and LBW.

    Almost 15 years ago it was hypothesized that polymorphisms of genes encoding enzymes involved in folate metabolism could lead to aberrant methylation of peri-centromeric regions of chromosome 21, favoring its abnormal segregation during maternal meiosis. Subsequently, more than 50 small case-control studies investigated whether or not maternal polymorphisms of folate pathway genes could be risk factors for the birth of a child with Down syndrome (DS), yielding conflicting and inconclusive res...

  10. Defect-mediated relaxation in the random tiling phase of a binary mixture: Birth, death and mobility of an atomic zipper

    International Nuclear Information System (INIS)

    This paper describes the mechanism of defect-mediated relaxation in a dodecagonal square-triangle random tiling phase exhibited by a simulated binary mixture of soft discs in 2D. We examine the internal transitions within the elementary mobile defect (christened the “zipper”) that allow it to move, as well as the mechanisms by which the zipper is created and annihilated. The structural relaxation of the random tiling phase is quantified and we show that this relaxation is well described by a model based on the distribution of waiting times for each atom to be visited by the diffusing zipper. This system, representing one of the few instances where a well defined mobile defect is capable of structural relaxation, can provide a valuable test case for general theories of relaxation in complex and disordered materials

    Full Text Available Increasing numbers of female patients survive cancer, but succumb to primary ovarian insufficiency after chemotherapy. We tested the hypothesis that Bortezomib (Bort protects ovaries from doxorubicin (DXR chemotherapy by treating female mice with Bort 1 hour prior to DXR. By preventing DXR accumulation in the ovary, Bort attenuated DXR-induced DNA damage in all ovarian cell types, subsequent γH2AFX phosphorylation, and resulting apoptosis in preantral follicles. Bort pretreatment extended the number of litters per mouse, improved litter size and increased pup weight following DXR treatment, thus increasing the duration of post-chemotherapy fertility and improving pup health. As a promising prophylactic ovoprotective agent, Bort does not interfere with cancer treatment, and is currently used as a chemotherapy adjuvant. Bort-based chemoprotection may preserve ovarian function in a non-invasive manner that avoids surgical ovarian preservation, thus diminishing the health complications of premature menopause following cancer treatment.

    Full Text Available Objective: The present study was done to know and compare the incidence of congenital malformations in singleton and multiple births in our hospital & compare with other studies. Methods: A retrospective study done by collecting the data from parturition register from Jan 2008 to Dec 2011 (4yrs from Cheluvamba Hospital attached to Mysore Medical College and Research Institute. Total number of the live births, still births, and abortions> 20 wks were collected. Details of multiple births such as maternal age, gestational age, sex & birth weight of the babies, U/S reports and congenital anomalies (CA were noted. Results: The total number of singleton births were 48700 and number of babies who had congenital malformations were 235 (48.25/10,000 births.Total number of multiple births were 579 including 10 triplets and number of babies who had CA were 11 (189.98/10,000 births, P<0.0001. In the present study sex of the babies were noted in all multiple births and zygosity could not be recorded. Among 579 multiple births 404 were of the Same Sex (SS and 165 were of Opposite Sex (OS in twins and 6 were of the same sex and 4 were of opposite sex in triplets. According to Weinberg formula 50% of same sex (SS twins are monozygotic and 50% are dizygotic twins. Among the 11 babies with CA, 4 monozygotic twins had anomalies related to twinning such as Acardia with TRAP sequence (3 twins, and Thoracophagus (1 twin.5 babies had CNS anomalies, 1 with cystic hygroma, 1 baby with multiple system affected. Conclusion: The incidence of birth defects is more in multiple births and especially in monozygotic twins. In the present days increase in twinning rate due to advanced maternal age, hereditary factors and use of ovulation inducing drugs, which results in premature and low birth wt babies associated with poor lung maturity.

  16. Triple-negative breast cancer risk in women is defined by the defect of estrogen signaling: preventive and therapeutic implications

    Full Text Available Zsuzsanna Suba National Institute of Oncology, Surgical and Molecular Tumor Pathology Centre, Budapest, Hungary Abstract: Epidemiologic studies strongly support that triple-negative breast cancers (TNBCs may be distinct entities as compared with estrogen receptor (ER+ tumors, suggesting that the etiologic factors, clinical characteristics, and therapeutic possibilities may vary by molecular subtypes. Many investigations propose that reproductive factors and exogenous hormone use differently or even quite inversely affect the risk of TNBCs and ER+ cancers. Controversies concerning the exact role of even the same risk factor in TNBC development justify that the biological mechanisms behind the initiation of both TNBCs and non-TNBCs are completely obscure. To arrive at a comprehensive understanding of the etiology of different breast cancer subtypes, we should also reconsider our traditional concepts and beliefs regarding cancer risk factors. Malignancies are multicausal, but the disturbance of proper estrogen signaling seems to be a crucial risk factor for the development of mammary cancers. The grade of defect in metabolic and hormonal equilibrium is directly associated with TNBC risk for women during their whole life. Inverse impact of menopausal status or parity on the development of ER+ and ER- breast cancers may not be possible; these controversial results derive from the misinterpretation of percentage-based statistical evaluations. Exogenous or parity-associated excessive estrogen supply is suppressive against breast cancer, though the lower the ER expression of tumors, the weaker the anticancer capacity. In women, the most important preventive strategy against breast cancers – included TNBCs – is the strict control and maintenance of hormonal equilibrium from early adolescence through the whole lifetime, particularly during the periods of great hormonal changes.

    Many of us are in the business of improving birth. Some of us are decades into our journeys of midwifery, whilst others are fresh students aspiring to give our best in this new profession. This article looks at ways to redeem birth from two aspects: for the mother; and for the midwife. I work in an international community in a developing country, in a privatised system. Although different from the UK, birth is birth. Women, their families and midwives will be able to relate to similar experiences. Ultimately my goals are likely to be the same as those in other parts of the world. I address issues of the workplaces in which we operate, the role of midwives in redeeming birth outcomes, and how we may better serve women and each other. PMID:27295755

Labor that occurs before 37 weeks of gestation (the period during which a baby develops in its mother) is defined as a preterm birth. In industrialized countries, 5%–10% of all births are preterm. Figures for preterm births are harder to obtain for low-income countries because of uncertainties about gestational dates but, in both rich and poor countries, preterm birth is a major cause of infant death and illness around the time...

    2012-08-01

    Full Text Available Abstract Background Patient safety is fundamental in high quality healthcare systems but despite an excellent record of perinatal care in Sweden some children still suffer from substandard care and unnecessary birth injuries. Sustainable patient safety improvements assume changes in key actors’ mental models, norms and culture as well as in the tools, design and organisation of work. Interventions positively affecting team mental models on safety issues are a first step to enhancing change. Our purpose was to study a national intervention programme for the prevention of birth injuries with the aim to elucidate how the main interventions of self-assessment, peer review, feedback and written agreement for change affected the teams and their mental model of patient safety, and thereby their readiness for change. Knowledge of relevant considerations before implementing this type of patient safety intervention series could thereby be increased. Methods Eighty participants in twenty-seven maternity units were interviewed after the first intervention sequence of the programme. A content analysis using a priori coding was performed in order to relate results to the anticipated outcomes of three basic interventions: self-assessment, peer review and written feedback, and agreement for change. Results The self-assessment procedure was valuable and served as a useful tool for elucidating strengths and weaknesses and identifying areas for improvement for a safer delivery in maternity units. The peer-review intervention was appreciated, despite it being of less value when considering the contribution to explicit outcome effects (i.e. new input to team mental models and new suggestions for actions. The feedback report and the mutual agreement on measures for improvements reached when signing the contract seemed exert positive pressures for change. Conclusions Our findings are in line with several studies stressing the importance of self-evaluation by

    Human chorionic gonadotropin (hCG) is implicated in the maintenance of uterine quiescence by down-regulating myometrial gap junctions during pregnancy, and it was considered as a strategy to prevent preterm birth after the occurrence of preterm labor. However, the effect of hCG on innate and adaptive immune cells implicated in parturition is poorly understood. Herein, we investigated the immune effects of hCG at the maternal-fetal interface during late gestation, and whether this hormone can safely prevent endotoxin-induced preterm birth. Using immunophenotyping, we demonstrated that hCG has immune effects at the maternal-fetal interface (decidual tissues) by: 1) increasing the proportion of regulatory T cells; 2) reducing the proportion of macrophages and neutrophils; 3) inducing an M1 → M2 macrophage polarization; and 4) increasing the proportion of T helper 17 cells. Next, ELISAs were used to determine whether the local immune changes were associated with systemic concentrations of progesterone, estradiol, and/or cytokines (IFNgamma, IL1beta, IL2, IL4, IL5, IL6, IL10, IL12p70, KC/GRO, and TNFalpha). Plasma concentrations of IL1beta, but not progesterone, estradiol, or any other cytokine, were increased following hCG administration. Pretreatment with hCG prevented endotoxin-induced preterm birth by 44%, proving the effectiveness of this hormone as an anti-inflammatory agent. However, hCG administration alone caused dystocia and fetal compromise, as proven by Doppler ultrasound. These results provide insight into the mechanisms whereby hCG induces an anti-inflammatory microenvironment at the maternal-fetal interface during late gestation, and demonstrate its effectiveness in preventing preterm labor/birth. However, the deleterious effects of this hormone on mothers and fetuses warrant caution. PMID:27146032

    As the first tributary of the River Oulujoki, the River Sanginjoki is one of the most important recreational areas in the Oulu region. It is also the closest potential reproduction area for salmon and trout using the Merikoski fishway. During flood peaks, occasional low pH values reduce the recreational and ecological value of the River Sanginjoki. The origin of low pH values was located as part of the 'City and Water - Improving the recreational value and ecological restoration of River Sanginjoki -project', during the years 2008-2011. This project involved largescale monitoring of the River Sanginjoki area for pH changes, while methods for preventing and reducing low pH values were tested. Based on the project's results, guidelines were drawn up for controlling problems associated with low pH values. The report also contains general information on the River Sanginjoki and its watershed, the river's ecological state and the development of its water quality. The results demonstrated a connection between low pH values and high discharges, but the lowest pH values were measured during summer and autumn rain floods in particular. A water sample analysis with other information showed that low pH values mainly originate in soil, land use and vegetation. The origin of acid runoff mainly lies in organic acids from peatlands and moss, but local factors such as acid sulphate soils and black shales may also contribute. Due to acidic peatlands, the water of the River Sanginjoki has naturally been slightly acidic, but ditch drainage of peat- and forestland has probably increased this effect. The effect of the restoration and water protection methods used in the project varied. Some methods proved effective and can be suggested for practical use at the Sanginjoki watershed, as well as other watersheds suffering from the same problems. Development of these methods should be continued, to improve their effectiveness and durability. Although defects due to

Data are reported for the Philadelphia Collaborative Preterm Prevention Project (PCPPP, a large RCT targeting risk factors for repeat preterm births among women who previously delivered premature ( Methods Design of the PCPPP incorporated strategies to maximize recruitment and retention. These included an advanced database system tracking follow-up status and assessment completion rates; cultural sensitivity training for staff; communication to the community and eligible women of the benefits of participation; financial incentives; assistance with transportation and supervised childcare services; and reminder calls for convenient, flexibly scheduled appointments. Analyses reported here: 1 compare recruitment projections to actual enrollment 2 explore recruitment bias; 3 validate the randomization process 4 document the extent to which contact was maintained and complete assessments achieved 5 determine if follow-up was conditioned upon socio-economic status, race/ethnicity, or other factors.

    infection with good immune response 28%. Women who were anti-HBe positive were a low-risk group, and their babies were most likely to remain free of HBV infection (occult or overt) and had good immune response to the vaccine. Maternal HBeAg-positive status and negativity for anti-HBe predicted not only overt but also any infection (both overt and occult) in babies. In addition, high maternal HBV DNA and treatment with vaccine alone were significant factors for overt HBV infection in babies. The current practice of administration of vaccine with HBIG at birth to babies born of HBsAg-positive mothers is not effective in preventing occult HBV infection in babies, which may be up to 40%. Because the most important risk factors for mother-to-baby transmission of HBV infection are the replicative status and high HBV DNA level in mothers; it will be worthwhile investigating the role of antivirals and HBIG administration during pregnancy to prevent mother-to-child transmission of HBV infection.

    Advocacy for homebirth is based on the strong assumption that birthing is a physiological process and does not require medical interventions unless things turn "wrong." Let us assume that something might always go wrong, for instance during Clara's birth when the placenta was still retained after three hours. What needs to be done? The moment the midwife entered the house she was endowed with a responsibility for any problem caused by her failure to give proper guidance. With this weight on her shoulder, and according to her training and experience, there was no other way for her than to suggest an intervention regarding the placenta. The two midwives, B, and C., might not agree on risk estimations, the nature of the intervention, whether it should be performed at home or in a hospital. The estimation of abnormalities, evaluation of risks and the procedures with which to handle them are the main practical difference between classic obstetrics and non-interventionist midwifery--by analogy, between allopathy and naturopathy. The rest (positive thinking) is basically literature. A delivery will not remain normal just because we decide it "must" be physiological. Dr. Barua, a professor of obstetrics in Pondicherry, pointed out that normal deliveries are rare--fewer than 10 percent in South India. What we have instead is either pathological or "natural" deliveries in which regenerative processes take care of abnormal situations. Unless she has developed sensitive hands, a birth assistant or midwife must rely on monitoring procedures to evaluate deviations from the normal process. Even with the greatest care, these procedures are intrusive in that they disconnect the parturient from her own sensations. While successful unattended homebirth stories emphasise the extraordinary power and sensitivity of a birthing woman, the whole dream seems to collapse in abnormal or pathological cases. It would have collapsed for Sonia as well, had she not discarded negative suggestions

    2011-10-01

    Full Text Available Abstract Background Women with a short cervical length in mid-trimester pregnancy have a higher risk of preterm birth and therefore a higher rate of neonatal mortality and morbidity. Progesterone can potentially decrease the number of preterm births and lower neonatal mortality and morbidity. Previous studies showed good results of progesterone in women with either a history of preterm birth or a short cervix. However, it is unknown whether screening for a short cervix and subsequent treatment in mid trimester pregnancy is effective in low risk women. Methods/Design We plan a combined screen and treat study among women with a singleton pregnancy without a previous preterm birth. In these women, we will measure cervical length at the standard anomaly scan performed between 18 and 22 weeks. Women with cervical length ≤ 30 mm at two independent measurements will be randomly allocated to receive either vaginal progesterone tablets or placebo between 22 and 34 weeks. The primary outcome of this trial is adverse neonatal condition, defined as a composite outcome of neonatal mortality and severe morbidity. Secondary outcomes are time to delivery, preterm birth rate before 32, 34 and 37 weeks, days of admission in neonatal intensive care unit, maternal morbidity, maternal admission days for preterm labour and costs. We will assess growth, physical condition and neurodevelopmental outcome of the children at two years of age. Discussion This study will provide evidence for the usefulness and cost-effectiveness of screening for short cervical length at the 18-22 weeks and subsequent progesterone treatment among low risk women.

    Fiber lasers have been receiving considerable attention because of their advantages of high power, high beam quality and high efficiency, and are expected as one of the desirable heat sources for high-speed and deep-penetration welding. In our researches, therefore, the effects of laser powers and their densities on the weld penetration and the formation of sound welds were investigated in welding of Type 304 austenitic stainless steel, A5052 aluminum alloy or high strength steel plates with four laser beams of about 0.12 to 1 mm in focused spot diameter, and their welding phenomena were observed with high-speed video cameras and X-ray transmission real-time imaging system. It was found that the laser power density exerted a remarkable effect on the increase in weld penetration at higher welding speeds, but on the other hand at low welding speeds deeper-penetration welds could be produced at higher power. Laser-induced plume behavior and its effect on weld penetration, and the mechanisms of spattering, underfilling, porosity and humping were elucidated, sound welds without welding defects could be produced under the improved welding conditions. In addition, importance of the development of focusing optics and the removal of a plume during remote welding will be emphasized in terms of the stable production of constant deep-penetration welds and the reduction in welding defects in high power laser welding.

  3. The mitochondrial quality control protein Yme1 is necessary to prevent defective mitophagy in a yeast model of Barth syndrome.

    Gaspard, Gerard J; McMaster, Christopher R

    2015-04-01

    The Saccharomyces cerevisiae TAZ1 gene is an orthologue of human TAZ; both encode the protein tafazzin. Tafazzin is a transacylase that transfers acyl chains with unsaturated fatty acids from phospholipids to monolysocardiolipin to generate cardiolipin with unsaturated fatty acids. Mutations in human TAZ cause Barth syndrome, a fatal childhood cardiomyopathy biochemically characterized by reduced cardiolipin mass and increased monolysocardiolipin levels. To uncover cellular processes that require tafazzin to maintain cell health, we performed a synthetic genetic array screen using taz1Δ yeast cells to identify genes whose deletion aggravated its fitness. The synthetic genetic array screen uncovered several mitochondrial cellular processes that require tafazzin. Focusing on the i-AAA protease Yme1, a mitochondrial quality control protein that degrades misfolded proteins, we determined that in cells lacking both Yme1 and Taz1 function, there were substantive mitochondrial ultrastructural defects, ineffective superoxide scavenging, and a severe defect in mitophagy. We identify an important role for the mitochondrial protease Yme1 in the ability of cells that lack tafazzin function to maintain mitochondrial structural integrity and mitochondrial quality control and to undergo mitophagy.

    Full Text Available Abstract Background Our objective was to estimate the effect of various childbirth care packages on neonatal mortality due to intrapartum-related events (“birth asphyxia” in term babies for use in the Lives Saved Tool (LiST. Methods We conducted a systematic literature review to identify studies or reviews of childbirth care packages as defined by United Nations norms (basic and comprehensive emergency obstetric care, skilled care at birth. We also reviewed Traditional Birth Attendant (TBA training. Data were abstracted into standard tables and quality assessed by adapted GRADE criteria. For interventions with low quality evidence, but strong GRADE recommendation for implementation, an expert Delphi consensus process was conducted to estimate cause-specific mortality effects. Results We identified evidence for the effect on perinatal/neonatal mortality of emergency obstetric care packages: 9 studies (8 observational, 1 quasi-experimental, and for skilled childbirth care: 10 studies (8 observational, 2 quasi-experimental. Studies were of low quality, but the GRADE recommendation for implementation is strong. Our Delphi process included 21 experts representing all WHO regions and achieved consensus on the reduction of intrapartum-related neonatal deaths by comprehensive emergency obstetric care (85%, basic emergency obstetric care (40%, and skilled birth care (25%. For TBA training we identified 2 meta-analyses and 9 studies reporting mortality effects (3 cRCT, 1 quasi-experimental, 5 observational. There was substantial between-study heterogeneity and the overall quality of evidence was low. Because the GRADE recommendation for TBA training is conditional on the context and region, the effect was not estimated through a Delphi or included in the LiST tool. Conclusion Evidence quality is rated low, partly because of challenges in undertaking RCTs for obstetric interventions, which are considered standard of care. Additional challenges for

  7. Primary prevention of Down's syndrome

    Directory of Open Access Journals (Sweden)

    2005-07-01

    Full Text Available Background: Antenatal screening has the capacity to detect more than 90% of Down's syndrome pregnancies leading to therapeutic abortion. Successes in recent years with such so-called 'secondary' prevention have not been matched with progress in primary prevention. Despite considerable research over many decades the principle cause of the disorder is unknown. Methods: This paper considers three potential primary prevention strategies, (1 avoiding reproduction at advanced maternal age, (2 pre-implantation genetic diagnosis for couples who are at high risk of Down's syndrome, and (3 folic acid supplementation. The principle aetiological hypotheses are also reviewed. Interpretation: A strategy of completing the family before a maternal age of 30 could more than halve the birth prevalence of this disorder. Women with a high a priori risk should have access to pre-implantation genetic diagnosis, which can lead to a reasonably high pregnancy rate with an extremely low risk of a Down's syndrome. The evidence suggesting an aetiological role for defective folate and methyl metabolism is not sufficient to justify an active preventative strategy of folic acid supplementation without performing a large clinical trial. Current supplementation policies designed to prevent neural tube defects may incidentally prevent Down's syndrome, provided a sufficiently high dose of folic acid is used. Further progress in primary prevention is hampered by limited aetiological knowledge and there is an urgent need to refocus research in that direction.

  8. Prevention of bone growth defects, increased bone resorption and marrow adiposity with folinic acid in rats receiving long-term methotrexate.

    Directory of Open Access Journals (Sweden)

    Chia-Ming Fan

    Full Text Available The underlying pathophysiology for bone growth defects in paediatric cancer patients receiving high dose methotrexate chemotherapy remains unclear and currently there are no standardized preventative treatments for patients and survivors. Using a model in young rats, we investigated damaging effects of long-term treatment with methotrexate on growth plate and metaphyseal bone, and the potential protective effects of antidote folinic acid. This study demonstrated that chronic folinic acid supplementation can prevent methotrexate-induced chondrocyte apoptosis and preserve chondrocyte columnar arrangement and number in the growth plate. In the metaphysis, folinic acid supplementation can preserve primary spongiosa heights and secondary spongiosa trabecular volume by preventing osteoblasts from undergoing apoptosis and suppressing methotrexate-induced marrow adiposity and osteoclast formation. Systemically, plasma of folinic acid supplemented rats, in comparison to plasma from rats treated with MTX alone, contained a significantly lower level of IL-1β and suppressed osteoclast formation in vitro in normal bone marrow cells. The importance of IL-1β in supporting plasma-induced osteoclast formation was confirmed as the presence of an anti-IL-1β neutralizing antibody attenuated the ability of the plasma (from MTX-treated rats in inducing osteoclast formation. Findings from this study suggest that folinic acid supplementation during chronic methotrexate treatment can alleviate growth plate and metaphyseal damages and therefore may be potentially useful in paediatric patients who are at risk of skeletal growth suppression due to chronic methotrexate chemotherapy.

    The curly tail mouse provides a model for neural tube defects (spina bifida and exencephaly) that are resistant to prevention by folic acid. The major ct gene, responsible for spina bifida, corresponds to a hypomorphic allele of grainyhead-like 3 (Grhl3) but the frequency of NTDs is strongly influenced by modifiers in the genetic background. Moreover, exencephaly in the curly tail strain is not prevented by reinstatement of Grhl3 expression. In the current study we found that expression of Mthfd1L, encoding a key component of mitochondrial folate one-carbon metabolism (FOCM), is significantly reduced in ct/ct embryos compared to a partially congenic wild-type strain. This expression change is not attributable to regulation by Grhl3 or the genetic background at the Mthfd1L locus. Mitochondrial FOCM provides one-carbon units as formate for FOCM reactions in the cytosol. We found that maternal supplementation with formate prevented NTDs in curly tail embryos and also resulted in increased litter size. Analysis of the folate profile of neurulation-stage embryos showed that formate supplementation resulted in an increased proportion of formyl-THF and THF but a reduction in proportion of 5-methyl THF. In contrast, THF decreased and 5-methyl THF was relatively more abundant in the liver of supplemented dams than in controls. In embryos cultured through the period of spinal neurulation, incorporation of labelled thymidine and adenine into genomic DNA was suppressed by supplemental formate, suggesting that de novo folate-dependent biosynthesis of nucleotides (thymidylate and purines) was enhanced. We hypothesise that reduced Mthfd1L expression may contribute to susceptibility to NTDs in the curly tail strain and that formate acts as a one-carbon donor to prevent NTDs. PMID:26924399

    Full Text Available Periconceptional folic acid use can often prevent neural tube defects (NTDs. Variants of genes involved in folate metabolism in mothers and children have been associated with occurrence of NTDs. We identified Irish families with individuals affected by neural tube defects. In these families, we observed that neural tube defects and birth defects overall occurred at a higher rate in the maternal lineage compared with the paternal lineage. The goal of this study was to look for evidence for genetic effects that could explain the discrepancy in the occurrence of these birth defects in the maternal vs. paternal lineage. We genotyped blood samples from 322 individuals from NTD-affected Irish families, identified through their membership in spina bifida associations. We looked for differences in distribution in maternal vs. paternal lineages of five genetic polymorphisms: the DHFR 19bp deletion, MTHFD1 1958G>A, MTHFR 1298A>C, MTHFR 677C>T, and SLC19A1 80A>G. In addition to looking at genotypes individually, we determined the number of genotypes associated with decreased folate metabolism in each relative (risk genotypes and compared the distribution of these genotypes in maternal vs. paternal relatives. Overall, maternal relatives had a higher number of genotypes associated with lower folate metabolism than paternal relatives (p=0.017. We expected that relatives would share the same risk genotype as the individuals with NTDs and/or their mothers. However, we observed that maternal relatives had an over-abundance of any risk genotype, rather than one specific genotype. The observed genetic effects suggest an epigenetic mechanism in which decreased folate metabolism results in epigenetic alterations related to the increased rate of NTDs and other birth defects seen in the maternal lineage. Future studies on the etiology of NTDs and other birth defects could benefit from including multigenerational extended families, in order to explore potential

    Objective:To describe the prevalence rates of neural tube defects (NTD) and yearly trends (1993-2000) in China. Methods: All the data were obtained from the Birth Defects Surveillance System in thirty counties/cities of China. The calculation of NTD prevalence rates and time trend analyses were based on the data for live (L) and stillbirths (S) only, the denominator used was total births (L+S). Linear regression analysis of the prevalence rate over years has been used to measure time trends. Results: In the period of 1993-2000, there were 1 264 neural tube defects among 1 189 126 total births in 30 counties/cities in China. The overall neural tube defects rate was 10.63 per 10000 births, and rates were higher (18.99 per 10 000 births) in the year 1993, lower (6.05 per 10 000 births) in 1998. The prevalence rates of anencephaly, spina bifida and encephalocele were 4.71,4.39 and 1.53 per 10 000 births respectively. Of all index NTD cases, anencephaly and spina bifida were most frequent, making up 44.3% and 41.3%, and encephalocele represented 14.4%. The stillbirth proportion was 69.3% over all index NTD cases, 95.4% in anencephaly cases, 43.7% in spina bifida, and 62.6% in encephalocele cases. Linear trend analysis indicated a significant decline for NTD rate (F=11.818, β=-0.814,P=0.014). Analysis by specific defect showed significant declines for the rates of anencephaly (P=0.004) and spina bifida (P=0.026), but no significant annual variation of encephalocele (P=0.227). Results of comparing with data reported from other surveillance systems (1994-1999) showed that the highest NTD rate (9.41 per 10000 births) was seen in China, nearly7 times the lowest rate (1.44 per 10000 births) in England and Wales. Conclusion: The overall neural tube defects rate in 30 counties/cities of China presented a significant downward trend between 1993 and 2000, and China still had the higher neural tube defects prevalence. %目的:描述中国30个县(市)1993

    The standards of health and health care for a sample of 1265 Christchurch children during the period birth to three years were examined. There was a systematic tendency for levels of health care and morbidity to vary with the child's birth placement: in general adopted children had the best standard of health care and the lowest rates of morbidity; children who entered single parent families at birth had the poorest standards of health care and the highest rates of morbidity. Statistical control for family social background including maternal age, education, ethnic status, family size and changes of residence tended to reduce the size of the observed differences. However, even when the results were controlled for these factors children in single parent families still has depressed levels of preventive health care and higher rates of hospital admission. Possible explanations of the differences are discussed. PMID:6944632

    Exposure to multimodal sensory stressors is an everyday occurrence and sometimes becomes very intense, such as during rave parties or other recreational events. A growing body of evidence suggests that strong environmental stressors might cause neuronal dysfunction on their own in addition to their synergistic action with illicit drugs. Mice were exposed to a combination of physical and sensory stressors that are reminiscent of those encountered in a rave party. However, this is not a model of rave because it lacks the rewarding properties of rave. A 14-h exposure to environmental stressors caused an impairment of hippocampal long-term potentiation (LTP) and spatial memory, and an enhanced phosphorylation of tau protein in the CA1 and CA3 regions. These effects were transient and critically depended on the activation of 5-HT2C serotonin receptors, which are highly expressed in the CA1 region. Acute systemic injection of the selective 5-HT2C antagonist, RS-102,221 (2 mg/kg, i.p., 2 min prior the onset of stress), prevented tau hyperphosphorylation and also corrected the defects in hippocampal LTP and spatial memory. These findings suggest that passive exposure to a combination of physical and sensory stressors causes a reversible hippocampal dysfunction, which might compromise mechanisms of synaptic plasticity and spatial memory for a few days. Drugs that block 5-HT2C receptors might protect the hippocampus against the detrimental effect of environmental stressors. PMID:26145279

    Full Text Available AbstractObjectiveNeural tube defects including anencephaly, encephalocele, and spina bifida are major congenital malformations with multifactorial etiology, and with a great variation in their prevalence in different populations. The study on the prevalence of these malformations may be helpful in planning strategies for their prevention. The aim of this epidemiologic descriptive study was to determine the prevalence of neural tube defects and to describe their birth characteristics in Motahhari hospital, Urmia, West Azerbaijan.Materials and MethodsA cross-section observational study was carried on the hospital-based charts of consecutive 13997 live-births and 124 stillbirths during the period January 2001 through June 2005. The defects categorized based on the domains of anencephaly, spina bifida, and encephalocele according to standard definitions.ResultsDuring this period, 117 cases were detected with neural tube defects, giving an overall  prevalence of 8.29/1000. Of 117 cases, 81 (69.23% cases were seen among stillbirths and 36 (30.77% cases among live-births, that is, the prevalence of neural tube defects for stillbirths and live-births were 653.2/1000 and 2.57/1000 respectively. The yearly prevalence varies between 6.99/1000 and 9.82/1000 over the 4.5-year period. The major lesion was  anencephaly with prevalence of 5.52/1000 (66.67% of all neural tube defects. Approximately, two-thirds (66.09% of cases were found in females. Weights of 73.36% of anencephalic cases wereless than 1000 grams.ConclusionIn this study, the prevalence of neural tube defects is among the highest reported rates. There was a significance difference in the prevalence of anencephaly, as the most prevalent NTD, between live-births and stillbirths. These findings may necessitate an intensive approach to periconceptional folic acid supplementation as a possible strategy to reduce the prevalence of these defects.

    Full Text Available Some of the most practical questions of perinatal medicine are regarding couples who have had pregnancy problems in the past, and their risk of having such problems in future pregnancies. For example, if a couple has a child with a birth defect, what are their chances that their next child will have a defect? The key to answering such questions is the availability of linked data such as those provided by the Medical Birth Registry of Norway. Such linked data provide a unique resource for addressing a broad range of questions in perinatal epidemiology. The Medical Birth Registry of Norway has been a pioneer in answering such questions.

    Full Text Available Abstract Background Folic acid supplementation reduces the risk of neural tube defects and congenital heart defects. The biological mechanisms through which folate prevents birth defects are not well understood. We explore the use of zebrafish as a model system to investigate the role of folate metabolism during development. Results We first identified zebrafish orthologs of 12 human folate metabolic genes. RT-PCR and in situ analysis indicated maternal transcripts supply the embryo with mRNA so that the embryo has an intact folate pathway. To perturb folate metabolism we exposed zebrafish embryos to methotrexate (MTX, a potent inhibitor of dihydrofolate reductase (Dhfr an essential enzyme in the folate metabolic pathway. Embryos exposed to high doses of MTX exhibited developmental arrest prior to early segmentation. Lower doses of MTX resulted in embryos with a shortened anterior-posterior axis and cardiac defects: linear heart tubes or incomplete cardiac looping. Inhibition of dhfr mRNA with antisense morpholino oligonucleotides resulted in embryonic lethality. One function of the folate pathway is to provide essential one-carbon units for dTMP synthesis, a rate-limiting step of DNA synthesis. After 24 hours of exposure to high levels of MTX, mutant embryos continue to incorporate the thymidine analog BrdU. However, additional experiments indicate that these embryos have fewer mitotic cells, as assayed with phospho-histone H3 antibodies, and that treated embryos have perturbed cell cycles. Conclusions Our studies demonstrate that human and zebrafish utilize similar one-carbon pathways. Our data indicate that folate metabolism is essential for early zebrafish development. Zebrafish studies of the folate pathway and its deficiencies could provide insight into the underlying etiology of human birth defects and the natural role of folate in development.

    Objective To observe the efficacy and adverse reactions of iron supplementation for preventing iron deficiency anemia of mild low birth weight infants at different ages, to provide reference for the prevention of iron deficiency anemia in low birth weight infant. Methods Totally 207 mild low birth weight infants were divided into 3 experimental groups (groupⅠ:starting iron supplement from the age of 2 weeks;groupⅡ:starting iron sup-plement from the age of 4 weeks; groupⅢ: starting iron supplement from the age of 2 months) and one control group (groupⅣ:without iron supplement) basing on the principle of parent informed consent. The iron supplement was 2 mg·kg-1·d-1 for subjects in the three experimental groups. Performed blood cell analysis of all subjects respec-tively at the beginning, age of 3 months and 6 months, compared the HGB, MCV, MCH, MCHC and anemia incidence rate of each group. Occurrence of adverse reaction were monitored at the same time. Results The hemoglobin levels of groupⅠ,ⅡandⅢwere higher than that of groupⅣ, and the incidence rates of groupⅠ,ⅡandⅢwere lower than that of the groupⅣ. The differences were statistically significant (P0.05);there were no statistically significant differences between the hemoglobin levels and anemia incidence rates of groupⅠand groupⅡ(P>0.05);GroupⅠshowed most adverse reactions. Conclusion It would be better to start iron sup-plementation at the age of 4 weeks so as to prevent iron deficiency anemia in mild low birth weight infants. Earlier iron supplementation will increase the incidence of adverse reaction, while later iron supplementation will increase the incidence of anemia.%目的:观察不同时期开始补铁以预防轻度低出生体重儿缺铁性贫血的疗效及不良反应发生情况,为预防低出生体重儿缺铁性贫血提供参考。方法将207例轻度低出生体重儿按家长知情同意原则分为三个实验组(Ⅰ组从2周龄

    2016-03-01

    We use ab initio calculations to estimate the formation energies of cation (transition-metal) antisite defects at oxide interfaces and to understand the basic physical effects that drive or suppress the formation of these defects. Antisite defects are found to be favored in systems with substantial charge transfer across the interface, while Jahn-Teller distortions and itinerant ferromagnetism can prevent antisite defects and help stabilize atomically sharp interfaces. Our results enable identification of classes of systems that may be more and less susceptible to the formation of antisite defects, and they motivate experimental studies and further theoretical calculations to elucidate the local structure and stability of oxide interface systems.

    2014-06-01

    Full Text Available The study aimed to describe the experiences of a group of nurse-midwives from the city of Campinas, SP, Brasil, regarding the transition process from attending institutionalized births to attending home births, in the period 2011 – 2013. The study is of the experience report type; the reflections, perceptions and challenges experienced in this process were collected using the technique of brainstorming. Content analysis, as proposed by Bardin, was used, which yielded four thematic categories: a the hospital experience; b living with obstetric violence; c returning home and d the challenges of home care. It is concluded that attending home births offers greater satisfaction to the nurses, even in the face of various obstacles, as it is possible to offer a care to the woman and new-born which covers both the concept of comprehensiveness and the current scientific recommendations.

    Objective: To analyze the reasons for quality defects of nursing occurring in the department of ob-stetrics and gynecology and advance the preventive strategies. Methods: All 59 cases of nursing accidents relevant to quality defects in our hospital were investigated by the method of retrospective study to figure out the relations be-tween quality defects of nursing and the factors like the nurses' educational background, professional titles and work-ing periods and advance the corresponding strategies to prevent the accident. Results: The main reasons for the acci-dents were related to nurses' not strictly following the checking system and their lacking the sense of responsibilities and the occurrence of the quality defects accidents was closely connected to the working periods of the nurse, in oth-er words, the nurses working lesser years were more prone to the accident of quality defects. Conclusion: Increasing the professional knowledge and skills of nurses and enhancing their senses of responsibilities are the effective path-way for reducing the nursing quality defects.%目的:探讨妇产科护理质量缺陷的原因,并提出相应防范对策。方法:采用回顾性研究方法,对本院妇产科发生的59例护理质量缺陷事件进行调查,分析护理质量缺陷与护理人员学历、职称、工作年限等的关系,提出相应防范对策。结果:护理人员未严格执行查对制度和责任心不强是造成护理质量缺陷的主要原因,护理质量缺陷的发生与护理人员工作年限存在密切联系,低年资护士更易发生护理质量缺陷事件。结论:加强护理人员的业务知识学习与技能训练、提高护理人员责任心是减少护理质量缺陷的有效途径。

    Objective: To investigate the effect of bed double check system on preventing clinical nursing defects. Methods:Establishment of bed double check system. Investigate the incidence rate of clinical nursing defects of nurs-es with different professional titles half a year before and after the implementation and incidence rate of inpatients’ nursing defects before and after the implementation, and evaluate the difference of nursing defects of nurses with differ-ent professional titles and the effect of bed double check system on prevention of nursing defects respectively. Results:The accidence rate of nursing defects of nurse practitioner and nursing staff inferior to nurse practitioner was higher than that of nurse in charge and its superiors and the difference had statistical significance(P<0.05);The accidence rate of clinical nursing defect reduced after the implementation of bed double check system, which had statistical signif-icance(P<0.05). Conclusion: As nurse practitioners and nurses with inferior professional titles easily have nursing defects, they are the important training objects in the management of patients’safety;the implementation of bed double check system can reduce the accidence rate of nursing defects, which is helpful for the management of patients’safety, thus it is worth popularizing.%目的:探讨实施床边双人核对制对预防临床护理缺陷的效果.方法:建立床边双人核对制.调查实施床边双人核对制前后各半年时间内不同职称护理人员护理缺陷发生率,以及实施床边双人核对制前后住院病人护理缺陷发生率,分别评估不同职称护士发生护理缺陷的差异和实施床边双人核对制预防护理缺陷的效果.结果:护师及以下职称护理人员发生护理缺陷的比例高于主管护师及以上职称的护士,差异有统计学意义(P<0.05);实施床边双人核对制后临床护理缺陷发生率降低,与实施前相比,

  11. Micronutrient deficiencies in pregnancy worldwide: health effects and prevention.

    2016-05-01

    Micronutrients, vitamins and minerals accessible from the diet, are essential for biologic activity. Micronutrient status varies widely throughout pregnancy and across populations. Women in low-income countries often enter pregnancy malnourished, and the demands of gestation can exacerbate micronutrient deficiencies with health consequences for the fetus. Examples of efficacious single micronutrient interventions include folic acid to prevent neural tube defects, iodine to prevent cretinism, zinc to reduce risk of preterm birth, and iron to reduce the risk of low birth weight. Folic acid and vitamin D might also increase birth weight. While extensive mechanistic and association research links multiple antenatal micronutrients with plausible materno-fetal health advantages, hypothesized benefits have often been absent, minimal or unexpected in trials. These findings suggest a role for population context in determining health responses and filling extensive gaps in knowledge. Multiple micronutrient supplements reduce the risks of being born with low birth weight, small for gestational age or stillborn in undernourished settings, and justify micronutrient interventions with antenatal care. Measurable health effects of gestational micronutrient exposure might persist into childhood but few data exists on potential long-term benefits. In this Review, we discuss micronutrient intake recommendations, risks and consequences of deficiencies, and the effects of interventions with a particular emphasis on offspring. PMID:27032981

    Full Text Available Introduction: It is known that mother/child deaths can be prevented by having safe births and taking routine postnatal home care. The aim of this study is to evaluate safety of births and postnatal home care visits of mothers having 0-11 month babies in the Center of Aydin. Methods: A cross-sectional design was used to study a group of 806 mothers. Multistage sampling method was used. Health stations was taken as cluster units. One rural-one urban health station from ten health-centers was selected by random sampling method. Safety of births, type of births, complications after births, home visits by health personel at postpartum period were asked. Results: Unsafe births was 6,0% in Aydin. It was found that family income, mother?s age/occupation/educational level, social security, number of children, father?s occupation/educational level and household size, effects the safety of births. 59,9% of women were visited by widwives at the postpartum period and mean number of visits were 2,0 ±1,7. At this period 9,4% of women had complications, and these complications were two times greater at unsafe births. Conclusion: Although Aydin is in the west part of Turkey, unsafe births and inadequate postpartum home visits are seen. In order to prevent these problems, health centers must take more active role.

  9. Prevalence at birth of congenital malformations in communities near the Hanford site

    International Nuclear Information System (INIS)

    The authors examined the prevalence of congenital malformations among births in Benton and Franklin counties, in southeastern Washington State, from 1968 through 1980. The Hanford Site is in this area and serves as a major employer. In addition, various agriculturally and chemically related activities are in the area. Hospital and vital records were used to identify 454 malformation cases among 23,319 births; this yielded a malformation rate of 19.6 per 1000 births, a rate similar to those reported in other studies. The rates of specific malformations ascertained during the first year of life were compared with combined rates from the states of Washington, Oregon, and Idaho from the Birth Defects Monitoring Program. Among defects that would be expected to be comparably ascertained, a statistically significant elevated rate of neural tube defects was observed (1.72 per 1000 births vs. 0.99 per 1000). Rates of cleft lip were significantly lower in Benton and Franklin counties than in the Birth Defects Monitoring Program (0.59 per 1,000 vs. 1.17 per 1000). For congenital heart defects, pyloric stenosis, and Down syndrome, which are often not diagnosed in the newborn period, Birth Defects Monitoring Program data did not offer appropriate comparisons. The rates of these defects did not appear to be elevated in relation to rates found in other relevant populations. When rates of neural tube defects were compared with those in populations other than the Birth Defects Monitoring Program, the Benton and Franklin county rates were still considered to be elevated. The increased bicounty rate cannot be explained by employment of the parents at Hanford or by the impact of plant emissions on the local population

    Objective Evidence for optimal timing of delivery for some pregnancy complications at late preterm gestation is limited. The purpose of this study was to identify center variation of indicated late preterm births. Study design We performed an analysis of singleton late preterm and term births from a large U.S. retrospective obstetrical cohort. Births associated with spontaneous preterm labor, major congenital anomalies, chorioamnionitis, and emergency cesarean were excluded. We used modified Poisson fixed effects logistic regression with interaction terms to assess center variation of indicated late preterm births associated with four medical/obstetric comorbidities after adjusting for socio-demographics, comorbidities, and hospital/provider characteristics. Results We identified 150,055 births from 16 hospitals; 9,218 were indicated late preterm births. We found wide variation of indicated late preterm births across hospitals. The extent of center variation was greater for births associated with preterm premature rupture of membranes (risk ratio [RR] across sites: 0.45-3.05), hypertensive disorders of pregnancy (RR across sites: 0.36-1.27), and placenta previa/abruption (RR across sites: 0.48-1.82). We found less center variation for births associated with diabetes (RR across sites: 0.65-1.39). Conclusion Practice variation in the management of indicated late preterm deliveries might be a source of preventable late preterm birth. PMID:27120474

    Congenital cardiac defects are anatomic conditions present at birth. Few references to such conditions in goats are available in the current scientific literature. This report describes, for the first time, a congenital cardiac disease clinically characterized by polypnea from birth and exercise intolerance in a 2-month-old pygmy goat. An atrioventricular dysplasia known as Ebstein's anomaly, an atrial septal defect, and a mild subaortic stenosis were ultrasonographically diagnosed.

  13. Defect Management in Agile Software Development

    Directory of Open Access Journals (Sweden)

    Rida Noor

    2014-03-01

    Full Text Available Agile development reduces the risk of developing low quality software in the first place by minimizing defects. In agile software development formal defect management processes help to build quality software. The core purpose of defect management is to make the software more effective and efficient in order to increase its quality. There are several methods for handling defects like defect prevention, defect discovery and resolution which are used by software developers and testers. Refactoring keeps the system clean by identifying and removing quality defects. To gain the full confidence of the customer defect management should be involved at every stage of development. Agile methodologies focus on delivering the software in form of short iterations. Thus each iteration helps to overcome defects and leads better development and end user satisfaction. This study paints the picture of handling the software defects using agile based Software Development Process.

    2010-01-01

    We give an introduction to the valuation theoretical phenomenon of "defect", also known as "ramification deficiency". We describe the role it plays in deep open problems in positive characteristic: local uniformization (the local form of resolution of singularities), the model theory of valued fields, the structure theory of valued function fields. We give several examples of algebraic extensions with non-trivial defect. We indicate why Artin-Schreier defect extensions play a central role and describe a way to classify them. Further, we give an overview of various results about the defect that help to tame or avoid it, in particular "stability" theorems and theorems on "henselian rationality", and show how they are applied. Finally, we include a list of open problems.

    Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth. These include, but are not limited to, nonmodifiable factors (eg, fetal sex, weight, plurality), potentially modifiable antepartum and intrapartum factors (eg, location of delivery, intent to intervene by cesarean delivery or induction for delivery, administration of antenatal corticosteroids and magnesium sulfate), and postnatal management (eg, starting or withholding and continuing or withdrawing intensive care after birth). Antepartum and intrapartum management options vary depending upon the specific circumstances but may include short-term tocolytic therapy for preterm labor to allow time for administration of antenatal steroids, antibiotics to prolong latency after preterm premature rupture of membranes or for intrapartum group B streptococci prophylaxis, and delivery, including cesarean delivery, for concern regarding fetal well-being or fetal malpresentation. Whenever possible, periviable births for which maternal or neonatal intervention is planned should occur in centers that offer expertise in maternal and neonatal care and the needed infrastructure, including intensive care units, to support such services.

    Full Text Available Background: The aim of this study was to investigate the maternal, foetal and obstetric parameters surrounding twin pregnancies. An attempt was made to find out the perinatal mortality and morbidity rates of twin births and to determine the underlying factors responsible for the increase in these rates. Methods: A one year observational study was done at Daga hospital Nagpur, which is a referral maternity hospital receiving a large number of antenatal patients daily. Perinatal mortality and morbidity rates, gestational age at delivery, birth weight, route of delivery, and caesarean section rates were analysed. Results: The commonest presentation in our study vertex/vertex presentation (62%. A large percentage of twins in our study had a normal delivery. 37% women had caesarean section. In our study nearly 17% of the neonates had birth weights <1.5 kg. In 51 % women the first baby had more birth weight than the second twin. Among the 95 twin births (190 twins studied, we had one discordant twins and one conjoined twins. Conclusions: Twin pregnancies are high risk pregnancies with more obstetrical complications compared to singleton pregnancies. Twin pregnancies have higher perinatal mortality and morbidity rates especially before 34 weeks of gestation. Hence deliveries should be performed in referral centres with competent NICUs.

  20. Preterm birth: Transition to adulthood.

    Science.gov (United States)

    Allen, Marilee C; Cristofalo, Elizabeth; Kim, Christina

    2010-01-01

    Preterm birth is associated with greater difficulty with transitions from childhood to adolescence to adulthood. Adolescents and young adults born preterm have higher rates of cerebral palsy, intellectual disability, cognitive impairment, learning disability, executive dysfunction, attention deficit disorder, and social-emotional difficulties than their peers born fullterm. Compared to individuals born fullterm, more preterm survivors have major neurodevelopmental or psychiatric disability and need financial supports and societal resources. Neuroimaging studies of adolescents and adults born preterm report higher rates of brain injury, differences in regional brain structure, and different brain circuits than in those born fullterm. Making the transition to adulthood is more difficult for young adults who were born preterm than their peers born fullterm, in that fewer complete high school and higher education, find and keep meaningful employment, and live independently from their parents. As a group, they do not tend to be risk-takers, and they have lower rates of alcohol abuse, use of illicit drugs, and criminal offenses than do their peers. Despite their many challenges, the majority of adults born preterm function well, form personal relationships, integrate well into their community, and are as satisfied with their quality of life as are their peers. Concerns regarding current preterm infants, with more extremely preterm survivors, overwhelming our medical, educational, and societal resources should serve as an impetus for research on prevention of preterm births and brain injury, as well as how to support and promote their ongoing neuromaturation and recovery from injury.
