Physician Awareness of Developmental Screening and Referral in the State of Kuwait.

PubMed

Hix-Small, Hollie; Alkherainej, Khaled

In the State of Kuwait, family physicians and pediatricians are responsible for identifying and referring children at risk of disability. The aims of this study were to better understand physician (1) use of developmental screening instruments, (2) referral practices for children at risk of developmental disability, (3) interpretation of screening results, and (4) anticipatory guidance topics prioritized over child screening. A nonprobability volunteer, self-selection sample of family physicians, general practitioners, and pediatricians (n = 398) completed a 60-item paper questionnaire. Items assessed included: (1) practitioner familiarity with, belief in, and use of screening instruments; (2) familiarity with early childhood intervention services; (3) perceived barriers to screening implementation; and (4) anticipatory topics prioritized over screening. Logistic regression was used to test a priori hypotheses. In general, family doctors and pediatricians practicing in public hospitals and primary health care centers in the State of Kuwait do not use or know how to use a developmental screening instrument, while over half prioritized immunization counseling over child screening. Screening confidence and training on using screening instruments increased the likelihood of tool use. Staff shortages, time constraints, and a perceived lack of Arabic screening instruments were barriers to tool use. Raising health care providers' awareness of standardized developmental screening instruments and establishment of an early identification system in the State of Kuwait are needed. Standardization and adaptation of technically sound Arabic-language screening tools for use in the State of Kuwait and physician training programs on screening are recommended.

A low-intensity armed conflict has been occurring for nearly a decade in southernmost region of Thailand. However, its impact on child health has not yet been investigated. This study aimed to estimate the prevalence of delayed child growth and development in the affected areas and to determine the association between the violence and health among children aged 1-5 years. A total of 498 children aged 1-5 years were recruited. Intensity of conflict for each sub-district was calculated as the 6-year average number of incidents per 100,000 population per year and classified into quartiles. Growth indices were weight-for-age, height-for-age, and weight-for-height, while development was measured by the Denver Development Screening Test II (Thai version). Food insecurity, child-rearing practice, health service accessibility, household sanitation, and depression among the caregivers were assessed using screening scales and questionnaires. Contextual information such as average income and numbers of violent events in each sub-district was obtained from external sources. Growth retardation was highly prevalent in the area as reported by rates of underweight, stunting, and wasting at 19.3%, 27.6% and 7.4%, respectively. The prevalence of developmental delay was also substantially high (37.1%). Multi-level analysis found no evidence of association between insurgency and health outcomes. However, children in areas with higher intensity of violence had a lower risk of delay in personal-social development (OR = 0.4; 95% CI = 0.2 - 0.9; p-value = 0.05). Unlike war refugees and internally-displaced persons in camp-like settings, the relationship between level of armed conflict and growth and developmental delay among children aged 1-5 years could not be demonstrated in the community setting of this study where food supply had been minimally perturbed.

2015-10-01

Sickle cell disease (SCD), a genetic disorder often reported late, can be identified early in life, and hot-spot areas may be identified to conduct genetic epidemiology studies. This study was undertaken to estimate prevalence and to identify hot spot area for SCD in Kalahandi district, by screening cord blood of neonates delivered at the district hospital as first-hand information. Kalahandi District Hospital selected for the study is predominated by tribal population with higher prevalence of SCD as compared to other parts of Odisha. Cord blood screening of SCD was carried out on 761 newborn samples of which 13 were screened to be homozygous for SCD. Information on area of parent's residence was also collected. Madanpur Rampur area was found to be with the highest prevalence of SCD (10.52 %) and the gene distribution did not follow Hardy-Weinberg Equation indicating un-natural selection. The approach of conducting neonatal screening in a district hospital for identification of SCD is feasible and appropriate for prioritizing area for the implementation of large-scale screening and planning control measures thereof.

School-based BMI and body composition screening and parent notification in California: methods and messages.

PubMed

Madsen, Kristine A; Linchey, Jennifer

2012-06-01

School-based body mass index (BMI) or body composition screening is increasing, but little is known about the process of parent notification. Since 2001, California has required annual screening of body composition via the FITNESSGRAM, with optional notification. This study sought to identify the prevalence of parental notification when screening is required but notification is optional, and the methods and messages used. Researchers conducted phone interviews with 851 school districts (89%) in California and reviewed notification materials from 54 districts. As of 2008, 53% of California districts notified parents of screening results. Many districts (24%) did not know the reason for their notification policy. Most districts notified parents via a letter mailed home (70%) or sent home with the child (18%). Whereas 79% of sample letters provided students' BMI, only 12% provided an explanation of BMI, and only half provided tips on what parents should do if concerned about their child's results. In California, where body composition screening is required but parent notification is not, approximately half of school districts elect to notify parents of results, most commonly via letter. Most letters do not explain BMI or percent body fat scores, nor do they suggest what parents should do for a child identified as at-risk. Further research to identify interpretable and actionable notification messages for parents will be critical if school-based BMI and body composition screening and notification is to reduce childhood obesity.

A plea for developmental motor screening in Canadian infants.

PubMed

Harris, Susan R

2016-04-01

Motor delays during infancy may be the first observable sign of a specific neurodevelopmental disability or of more global developmental delays. The earlier such disorders are identified, the sooner these infants can be referred for early intervention services. Although developmental motor screening is strongly recommended in other Western countries, Canada has yet to provide a developmental surveillance and screening program. Ideally, screening for motor disabilities should occur as part of the 12-month well-baby visit. In advance of that visit, parents can be provided with a parent-screening questionnaire that they can complete and bring with them to their 12-month office visit. Interpretation of the parent-completed questionnaire takes only 2 min to 3 min of the health care professional's time and, based on the results, can either reassure parents that their infant is developing typically, or lead to a referral for standardized motor screening or assessment by a paediatric physical or occupational therapist.

Nair, M K C; Radhakrishnan, S Rekha

2004-03-01

Poverty, the root cause of the existence of slums or settlement colonies in urban areas has a great impact on almost all aspects of life of the urban poor, especially the all-round development of children. Examples from countries, across the globe provide evidence of improved early child development, made possible through integrated slum improvement programs, are few in numbers. The observed 2.5% prevalence of developmental delay in the less than 2 year olds of deprived urban settlements, the presence of risk factors for developmental delay like low birth weight, birth asphyxia, coupled with poor environment of home and alternate child care services, highlights the need for simple cost effective community model for promoting early child development. This review on early child development focuses on the developmental status of children in the deprived urban settlements, who are yet to be on the priority list of Governments and international agencies working for the welfare of children, the contributory nature-nurture factors and replicable working models like infant stimulation, early detection of developmental delay in infancy itself, developmental screening of toddlers, skill assessment for preschool children, school readiness programs, identification of mental sub-normality and primary education enhancement program for primary school children. Further, the review probes feasible intervention strategies through community owned early child care and development facilities, utilizing existing programs like ICDS, Urban Basic Services and by initiating services like Development Friendly Well Baby Clinics, Community Extension services, Child Development Referral Units at district hospitals and involving trained manpower like anganwadi/creche workers, public health nurses and developmental therapists. With the decentralization process the local self-government at municipalities and city corporations are financially equipped to be the prime movers to initiate, monitor and promote early child development programs, to emerge as a part and parcel of community owned sustainable development process.

Moore, Jessica A.; Welch, Therese R.; Halterman, Jill S.; Hyman, Susan L.

2016-01-01

BACKGROUND AND OBJECTIVES: Refugee children are at high developmental risk due to dislocation and deprivation. Standardized developmental screening in this diverse population is challenging. We used the Health Belief Model to guide key-informant interviews and focus groups with medical interpreters, health care providers, community collaborators, and refugee parents to explore key elements needed for developmental screening. Cultural and community-specific values and practices related to child development and barriers and facilitators to screening were examined. METHODS: We conducted 19 interviews and 2 focus groups involving 16 Bhutanese-Nepali, Burmese, Iraqi, and Somali participants, 7 community collaborators, and 6 providers from the Center for Refugee Health in Rochester, New York. Subjects were identified through purposive sampling until data saturation. Interviews were recorded, coded, and analyzed using a qualitative framework technique. RESULTS: Twenty-one themes in 4 domains were identified: values/beliefs about development/disability, practices around development/disability, the refugee experience, and feedback specific to the Parents’ Evaluation of Developmental Status screen. Most participants denied a word for “development” in their primary language and reported limited awareness of developmental milestones. Concern was unlikely unless speech or behavior problems were present. Physical disabilities were recognized but not seen as problematic. Perceived barriers to identification of delays included limited education, poor healthcare knowledge, language, and traditional healing practices. Facilitators included community navigators, trust in health care providers, in-person interpretation, visual supports, and education about child development. CONCLUSIONS: Refugee perspectives on child development may influence a parent’s recognition of and response to developmental concerns. Despite challenges, standardized screening was supported.

The goal of this statement was to review the available literature on surveillance, screening, evaluation, and management strategies and put forward a scientific statement that would comprehensively review the literature and create recommendations to optimize neurodevelopmental outcome in the pediatric congenital heart disease (CHD) population. A writing group appointed by the American Heart Association and American Academy of Pediatrics reviewed the available literature addressing developmental disorder and disability and developmental delay in the CHD population, with specific attention given to surveillance, screening, evaluation, and management strategies. MEDLINE and Google Scholar database searches from 1966 to 2011 were performed for English-language articles cross-referencing CHD with pertinent search terms. The reference lists of identified articles were also searched. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. A management algorithm was devised that stratified children with CHD on the basis of established risk factors. For those deemed to be at high risk for developmental disorder or disabilities or for developmental delay, formal, periodic developmental and medical evaluations are recommended. A CHD algorithm for surveillance, screening, evaluation, reevaluation, and management of developmental disorder or disability has been constructed to serve as a supplement to the 2006 American Academy of Pediatrics statement on developmental surveillance and screening. The proposed algorithm is designed to be carried out within the context of the medical home. This scientific statement is meant for medical providers within the medical home who care for patients with CHD. Children with CHD are at increased risk of developmental disorder or disabilities or developmental delay. Periodic developmental surveillance, screening, evaluation, and reevaluation throughout childhood may enhance identification of significant deficits, allowing for appropriate therapies and education to enhance later academic, behavioral, psychosocial, and adaptive functioning.

2013-09-01

Latino-white disparities in age at autism spectrum disorder (ASD) diagnosis may be modified by primary care pediatrician (PCP) practices and beliefs. The objectives of this study were to assess ASD and developmental screening practices, attitudes toward ASD identification in Latino children, and barriers to ASD identification for Latino children, in a sample of 267 California PCPs. In mail-based PCP survey, we assessed rates of bilingual general developmental and ASD screening, perceptions of parent ASD knowledge in Latino and white families, reports of difficulty assessing for ASDs in Latino and white children, and perceptions of barriers to early ASD identification for Latinos. Although 81% of PCPs offered some form of developmental screening, 29% of PCPs offered Spanish ASD screening per American Academy of Pediatrics guidelines, and only 10% offered both Spanish general developmental and Spanish ASD screening per American Academy of Pediatrics guidelines. Most PCPs thought that Latino (English and Spanish primary family language) parents were less knowledgeable about ASDs than white parents. PCPs had more difficulty assessing ASD risk for Latino children with Spanish primary family language than for white children, even when the PCP conducted recommended ASD screening or had >25% Latino patients. The most frequent barrier to ASD identification in Latinos was access to developmental specialists. Multiple factors in the primary care setting may contribute to delayed ASD identification for Latinos. Promoting language-appropriate screening, disseminating culturally appropriate ASD materials to Latino families, improving the specialist workforce, and providing PCP support in screening and referral of Latino children may be important ways to reduce racial and ethnic differences in care.

Maternal well-being and its association to risk of developmental problems in children at school entry

PubMed Central

2010-01-01

Background Children at highest risk of developmental problems benefit from early identification and intervention. Investigating factors affecting child development at the time of transition to school may reveal opportunities to tailor early intervention programs for the greatest effectiveness, social benefit and economic gain. The primary objective of this study was to identify child and maternal factors associated with children who screened at risk of developmental problems at school entry. Methods An existing cohort of 791 mothers who had been followed since early pregnancy was mailed a questionnaire when the children were aged four to six years. The questionnaire included a screening tool for developmental problems, an assessment of the child's social competence, health care utilization and referrals, and maternal factors, including physical health, mental health, social support, parenting morale and sense of competence, and parenting support/resources. Results Of the 491 mothers (62%) who responded, 15% had children who were screened at high risk of developmental problems. Based on a logistic regression model, independent predictors of screening at high risk for developmental problems at age 5 were male gender (OR: 2.3; 95% CI: 1.3, 4.1), maternal history of abuse at pregnancy (OR: 2.4; 95% CI: 1.3, 4.4), and poor parenting morale when the child was 3 years old (OR: 3.9; 95% CI: 2.1, 7.3). A child with all of these risk factors had a 35% predicted probability of screening at high risk of developmental problems, which was reduced to 13% if maternal factors were favourable. Conclusions Risk factors for developmental problems at school entry are related to maternal well being and history of abuse, which can be identified in the prenatal period or when children are preschool age.

For early detection of autism, it is difficult to maintain an efficient level of sensitivity and specificity based on observational data from a single screening. The Extraction and Refinement (E&R) Strategy utilizes a public children's health surveillance program to produce maximum efficacy in early detection of autism. In the extraction stage, all cases at risk of childhood problems, including developmental abnormality, are identified; in the refinement stage, cases without problems are excluded, leaving only cases with conclusive diagnoses. The city of Yokohama, Japan, conducts a routine child health surveillance program for children at 18 months in which specialized public health nurses administer YACHT-18 (Young Autism and other developmental disorders CHeckup Tool), a screening instrument to identify children at risk for developmental disorders. Children who screen positive undergo further observation, and those without disorders are subsequently excluded. To study the efficacy of early detection procedures for developmental disorders, including autism, 2,814 children born in 1988, examined at 18 months of age, and not already receiving treatment for diseases or disorders were selected. In the extraction stage, 402 (14.3%) children were identified for follow-up. In the refinement stage, 19 (.7%) of these were referred to the Yokohama Rehabilitation Center and diagnosed with developmental disorders. The extraction stage produced four false negatives, bringing total diagnoses of developmental disorders to 23 (.8%) - including 5 with autistic disorder and 9 with pervasive developmental disorder - not otherwise specified (PDDNOS). Sensitivity was 60% for autistic disorder and 82.6% for developmental disorders. Specificity for developmental disorders rose to 100% with the E&R Strategy. Picture cards used in YACHT-18 provided a finer screen that excluded some false positive cases. An extraction and refinement methodology utilizing child health surveillance programs achieve high efficacy for early detection of autism.

Midlands Province started implementing the Isoniazid (INH) preventive therapy (IPT) program in January 2013. Shurugwi and Gokwe North were the piloting district hospitals. In May 2014, four more districts hospitals (Gokwe South, Gweru, Kwekwe and Zvishavane) started implementing IPT. Shurugwi District decentralized the program to its rural health facilities in January 2014. A review of the Shurugwi IPT program, 2013 data, indicated that the majority of eligible clients were not started on IPT. None out of the 400 eligible clients were started on IPT in November against the 100% target according to the World Health Organization and the National Tuberculosis (TB) Program. We conducted a study to evaluate the IPT program in Shurugwi District from January 2013 to August 2014. The logical framework approach was used to evaluate inputs, processes, outputs and outcomes of the IPT program. An interviewer administered questionnaire was used to collect data from key informants. Checklists were used to collect data from IPT program records. Sixteen health facilities were implementing IPT in Shurugwi District. All the facilities had TB screening tools and three did not have TB screening algorithms. The district experienced medicine stock outs in 2013. One formal training at district level and on job trainings in implementing health facilities were done. From January 2013 to August 2014, Shurugwi District screened 6794 antiretroviral (ART) clients for TB. Out of those screened, 5255 were eligible for IPT and 2831 (54%) were started on IPT. A total of 700 clients had completed the IPT 6 month's course by August 2014. The dropout rate due to INH toxicity and TB was 0.6% (n = 18) and 0.3% (n = 8) respectively. Fifty-three advocacy and community sensitization meetings were done. The program had no Information Education and Communication (IEC) materials. The IPT program in Shurugwi District achieved half its target. This could be due to inadequate formally trained staff, lack of IEC materials, inadequate advocacy and community sensitization, non-availability of the INH 300 mg single dose and inadequate INH 100 mg dose tablets in 2013. To improve the IPT program, there is need for routine advocacy, communication and social mobilization.

Rates of detection of developmental problems at the 18-month well-baby visit by family physicians' using four evidence-based screening tools compared to usual care: a randomized controlled trial.

Early and regular developmental screening can improve children's development through early intervention but is insufficiently used. Most developmental problems are readily evident at the 18-month well-baby visit. This trial's purpose is to: (1) compare identification rates of developmental problems by GPs/family physicians using four evidence-based tools with non-evidence based screening, and (2) ascertain whether the four tools can be completed in 10-min pre-visit on a computer. We compared two approaches to early identification via random assignment of 54 families to either: 'usual care' (informal judgment including ad-hoc milestones, n = 25); or (2) 'Evidence-based' care (use of four validated, accurate screening tools, n = 29), including: the Parents' Evaluation of Developmental Status (PEDS), the PEDS-Developmental Milestones (PEDS-DM), the Modified Checklist for Autism in Toddlers (M-CHAT) and PHQ9 (maternal depression). In the 'usual care' group four (16%) and in the evidence-based tools group 18 (62%) were identified as having a possible developmental problem. In the evidence-based tools group three infants were to be recalled at 24 months for language checks (no specialist referrals made). In the 'usual care' group four problems were identified: one child was referred for speech therapy, two to return to check language at 24 months and a mother to discuss depression. All forms were completed on-line within 10 min. Despite higher early detection rates in the evidence-based care group, there were no differences in referral rates between evidence-based and usual-care groups. This suggests that clinicians: (1) override evidence-based screening results with informal judgment; and/or (2) need assistance understanding test results and making referrals. Possible solutions are improve the quality of information obtained from the screening process, improved training of physicians, improved support for individual practices and acceptance by the regional health authority for overall responsibility for screening and creation of a comprehensive network. © 2016 John Wiley & Sons Ltd.

Giorgi, Roch; Reynaud, Julie; Wait, Suzanne; Seradour, Brigitte

2005-11-01

The purpose is to measure the costs of the new national breast cancer screening programme in France and to compare these with those of the previous programme in the Bouches-du-Rhône district. Direct screening costs and costs related to diagnosis and assessment were collected. Costs are presented by screening period, by organisms involved in the screening program and by corresponding phase within the screening process. The total cost of the screening program total cost has increased from 5587487 euros to 9345469 euros between the two campaigns. The main reasons are the investment costs in the new screening program, the increase in the target population and the increased fee for programs. This study presents a first estimate of the costs related to the new national breast cancer screening program. Results of this study may help to guide future decisions on the further development of breast cancer screening in France.

2016-01-01

The Modified Checklist for Autism in Toddlers Revised-Albanian screener (M-CHAT-R/-A) was used to screen 2,594 toddlers, aged 16-30 months, at well-child visits. Two hundred fifty three (9.75%) screened positive; follow up on failed items were conducted by phone with 127 (50%); the remainder were lost to follow-up. Twenty-six toddlers (21%) continued to screen positive; 19 received full evaluations, which assessed for ASD with the Autism Diagnostic Observation Schedule and developmental delays with the Parents Assessment of Developmental Status – Developmental Milestones. All evaluated children had significant delays; 17 of the 19 met criteria for Autism/ASD. Removal of three items improved performance. Although Albania and the US are quite different in culture and language, key features of autism appeared very similar. PMID:27491423

Maseko, Fresier C; Chirwa, Maureen L; Muula, Adamson S

2015-01-01

Cervical cancer remains the leading cause of cancer death among women in sub-Saharan Africa. In Malawi, very few women have undergone screening and the incidence of cervical cancer is on the increase as is the case in most developing countries. We aimed at exploring and documenting health system gaps responsible for the poor performance of the cervical cancer prevention program in Malawi. The study was carried out in 14 randomly selected districts of the 29 districts of Malawi. All cervical cancer service providers in these districts were invited to participate. Two semi-structured questionnaires were used, one for the district cervical cancer coordinators and the other for the service providers. The themes of both questionnaires were based on World Health Organization (WHO) health system frameworks. A checklist was also developed to audit medical supplies and equipment in the cervical cancer screening facilities. The two questionnaires together with the medical supplies and equipment checklist were piloted in Chikwawa district before being used as data collection tools in the study. Quantitative data were analyzed using STATA and qualitative in NVIVO. Forty-one service providers from 21 health facilities and 9 district coordinators participated in the study. Our findings show numerous health system challenges mainly in areas of health workforce and essential medical products and technologies. Seven out of the 21 health facilities provided both screening and treatment. RESULTS showed challenges in the management of the cervical cancer program at district level; inadequate service providers who are poorly supervised; lack of basic equipment and stock-outs of basic medical supplies in some health facilities; and inadequate funding of the program. In most of the health facilities, services providers were not aware of the policy which govern their work and that they did not have standards and guidelines for cervical cancer screening and treatment. Numerous health system challenges are prevailing in the cervical cancer prevention program in Malawi. These challenges need to be addressed if the health system is to improve on the coverage of cervical cancer screening and treatment.

To Screen or Not to Screen? A Decision Analysis of the Utility of Screening for Developmental Dysplasia of the Hip

PubMed Central

Mahan, Susan T.; Katz, Jeffrey N.; Kim, Young-Jo

2009-01-01

Background: The United States Preventive Services Task Force recently determined that they could not recommend any screening strategies for developmental dysplasia of the hip. Disparate findings in the literature and treatment-related problems have led to confusion about whether or not to screen for this disorder. The purpose of the present study was to determine, with use of expected-value decision analysis, which of the following three strategies leads to the best chance of having a non-arthritic hip by the age of sixty years: (1) no screening for developmental dysplasia of the hip, (2) universal screening of newborns with both physical examination and ultrasonography, or (3) universal screening with physical examination but only selective use of ultrasonography for neonates considered to be at high risk. Methods: Developmental dysplasia of the hip, avascular necrosis, and the treatment algorithm were carefully defined. The outcome was determined as the probability of any neonate having a non-arthritic hip through the age of sixty years. A decision tree was then built with decision nodes as described above, and chance node probabilities were determined from a thorough review of the literature. Foldback analysis and sensitivity analyses were performed. Results: The expected value of a favorable hip outcome was 0.9590 for the strategy of screening all neonates with physical examination and selective use of ultrasonography, 0.9586 for screening all neonates with physical examination and ultrasonography, and 0.9578 for no screening. A lower expected value implies a greater risk for the development of osteoarthritis as a result of developmental dysplasia of the hip or avascular necrosis; thus, the optimum strategy was selective screening. This model was robust to sensitivity analysis, except when the rate of missed dysplasia rose as high as 4/1000 or the rate of treated hip subluxation/dislocation was the same; then, the optimum strategy was to screen all neonates with both physical examination and ultrasonography. Conclusions: Our decision analytic model indicated that the optimum strategy, associated with the highest probability of having a non-arthritic hip at the age of sixty years, was to screen all neonates for hip dysplasia with a physical examination and to use ultrasonography selectively for infants who are at high risk. Additional data on the costs and cost-effectiveness of these screening policies are needed to guide policy recommendations. Level of Evidence: Economic and decision analysis Level II. See Instructions to Authors for a complete description of levels of evidence. PMID:19571094

Coverage of neonatal screening: failure of coverage or failure of information system

PubMed Central

Ades, A; Walker, J; Jones, R; Smith, I

2001-01-01

OBJECTIVES—To evaluate neonatal screening coverage using data routinely collected on the laboratory computer.
SUBJECTS—90 850 births in 14 North East Thames community provider districts over a 21 month period.
METHODS—Births notified to local child health computers are electronically copied to the neonatal laboratory computer system, and incoming Guthrie cards are matched against these birth records before testing. The computer records for the study period were processed to estimate the coverage of the screening programme.
RESULTS—Out of an estimated 90 850 births notified to child health computers, all but 746 (0.82%) appeared to have been screened or could be otherwise accounted for (0.14% in non-metropolitan districts, 0.39% in suburban districts, and 1.68% in inner city districts). A further 893 resident infants had been tested, but could not be matched to the list of notified resident births. The calculated programme coverage already exceeds the 99.5% National Audit Programme standard in 7/14 districts. Elsewhere it is not clear whether it is coverage or recording of coverage that is low.
CONCLUSION—Previous reports of low coverage may have been exaggerated. High coverage can be shown using routine information systems. Design of information systems that deliver accurate measures of coverage would be more useful than comparison of inadequately measured coverage with a national standard. The new NHS number project will create an opportunity to achieve this.

School district resources and identification of children with autistic disorder.

PubMed

Palmer, Raymond F; Blanchard, Stephen; Jean, Carlos R; Mandell, David S

2005-01-01

We estimated the effect of community and school district resources on the identification of children with autistic disorder. Latent growth curve regression models were applied to school district-level data from one large state. The rate of identification of autistic disorder increased on average by 1.0 child per 10000 per year (P<.001), with statistically significant district variation. After adjustment for district and community characteristics, each increase in decile of school revenue was associated with an increase of 0.16 per 10000 children identified with autistic disorder. The proportion of economically disadvantaged children per district was inversely associated with autistic disorder cases. District revenue was associated with higher proportions of children identified with autistic disorder at baseline and increasing rates of identification when measured longitudinally. Economically disadvantaged communities may need assistance to identify children with autistic spectrum disorders and other developmental delays that require attention.

Kusiluka, L. J. M.; Karimuribo, E. D.; Mdegela, R. H.; Luoga, E. J.; Munishi, P. K. T.; Mlozi, M. R. S.; Kambarage, D. M.

A study on the prevalence of water-borne zoonotic pathogens in water, cattle and humans was conducted in six villages in Dodoma Rural (5) and Bagamoyo (1) districts, Tanzania. Water sources were screened for faecal coliform organisms, thermophilic Campylobacter, Salmonella, Cryptosporidium and Giardia. Faecal samples from cattle and humans were also analysed for the above specific pathogens. Results indicate that 70.8% ( n = 48) of the water sources screened were contaminated with faecal coliform organisms. Water sources in two villages, one each in Dodoma Rural and Bagamoyo districts were also contaminated with Giardia lamblia. The overall prevalence of Campylobacter jejuni in cattle in the two study areas was 2.3% ( n = 942) and at least one animal in each village was infected with C. jejuni. Cryptosporidium parvum was detected in 0.5% ( n = 942) of the cattle examined in three villages in Dodoma district. Salmonella spp. was demonstrated in only 1.4% ( n = 144) of the cattle in Chalinze village in Dodoma Rural district while G. lamblia was only detected in 1.5% ( n = 202) of the animals examined in Chamakweza village in Bagamoyo district. Nine (1.9%) of the people screened at three heath centres in the study areas were infected with C. jejuni while 3.7% ( n = 484) of the people had C. parvum oocysts. G. lamblia was detected in 2.5% of the 202 people screened at the Chalinze health centre in Bagamoyo district. Analysis of the secondary data revealed that clinical complaints related to enteric diseases were prevalent in humans in the two areas throughout the year and the prevalence varied from about 1% to 25% in both <5 years and ⩾5 years patients. In conclusion, this study has highlighted the possible public health risks, which may be associated with keeping of animals and sharing of water sources between humans and animals.

Value of parents' estimates of children's developmental ages.

PubMed

Glascoe, F P; Sandler, H

1995-11-01

To determine whether parents' estimates of children's developmental ages can function as a prescreening technique. Parents of 234 children from birth to 77 months of age seeking well-child care in pediatric offices were queried in two separate studies. In the first study, parents were asked to give an estimate of their child's overall developmental age and, in the second study, to estimate ages in each of six developmental domains. Children were administered a range of screening measures of intelligence, speech-language, and adoptive behavior. The overall age-estimate, if less than chronologic age, was 75% sensitive to likely developmental problems and, if equal to or greater than chronologic age, was 90% specific in identifying children likely to have typical development. Age estimates for each developmental domain were 81% sensitive to likely developmental problems if less than chronologic age in the domains of fine motor, language, grass motor, or behavior, and 62% specific if equal to or greater than chronologic age. Estimates at or below chronologic age in receptive language or personal-social domains were 90% sensitive and 43% specific in identifying likely behavior problems. There were no differences in the accuracy of parents estimates on the basis of children's age, gender, race, parents' level of education, or parenting experience. Parents' overall age-estimates provided a sensitive and specific indicator of global developmental status, but insufficient information about strengths and weaknesses to enable focused referrals for services. In contrast, discrete patterns of age estimates in each developmental domain sensitively discriminated children with developmental versus behavioral problems, although specificity was limited. Age estimates appear to be a potentially helpful method for identifying a subset of children in need of thorough screening, although further research is needed on a larger sample given diagnostic rather than screening tests.

2015-09-01

To determine the associations between autism developmental profiles and cooperation with an oral health screening among preschool children with autism spectrum disorders (ASDs). A random sample of Special Child Care Centres registered with the Government Social Welfare Department in Hong Kong was selected (19 out of 37 Centres). All preschool children with ASDs were invited to participate in the oral health survey and 347 children agreed to participate (among 515 invited). A checklist of autism developmental profiles: (1) level of cognitive functioning, (2) social skills development, (3) communication skills development, (4) reading skills and (5) challenging behaviours was ascertained. Feasibility of conducting oral health screening in preschool children with ASDs was associated with their cognitive functioning (p = 0.001), social skills development (p = 0.002), communication skills development (p < 0.001), reading skills (p < 0.001) and challenging behaviours (p = 0.06). In regression analyses accounting for age (in months) and gender, inability to cooperate with an oral health screening was associated with high level of challenging behaviours (OR 10.50, 95 % CI 2.89-38.08, p < 0.001) and reduced cognitive functioning (OR 5.29, 95 % CI 1.14-24.61, p = 0.034). Age (in months) was positively associated with likelihood of cooperative behaviour with an oral health screening (OR 1.06, 95 % CI 1.03, 1.08, p < 0.001). Feasibility of conducting population-wide oral health screening among preschool children with ASDs is associated with their developmental profiles; and in particular levels of cognitive functioning, and challenging behaviours.

Significant prevalence rates of adolescent scoliosis in China were suggested in previous studies. However, school screenings for adolescent scoliosis have been suspended due to low rates of positive detection under the past screening system in China. The present study was undertaken to screen for adolescent scoliosis in middle school students under a modern assessment system in a district of Shanghai. We performed a population-based, cross-sectional study of a middle school scoliosis screening program in the Jingan district. In 2015, schoolchildren were initially screened by visual inspection of clinical signs and the forward-bending test. Suspected cases were referred for radiography in hospital for scoliosis diagnosis. A total of 5327 middle school students (grades 6-8) were screened with 520 (9.76%) positives (the positive rates of girls and boys at 15.28% and 4.59%, respectively) and no statistically significant difference among grades. Only 301 positives (57.9%) followed the referral for hospital radiography. There were 102 cases (33.9%) that were diagnosed with scoliosis by radiography criteria (Cobb angle ≥10°) including mild scoliosis (Cobb 10-25) for 94 cases and moderate scoliosis (Cobb 25-40) for 8 cases, and false-positives (Cobb 0) for 39 cases. The putative prevalence rate was estimated as 1.9% from the referred students. Under an accurate and modern assessment system, school screenings can detect scoliosis at a significant rate, but awareness of scoliosis risks is needed for residents in China to take up referrals for hospital diagnosis after school screenings.

To describe CDC Kerala experience of establishing an at-risk baby clinic and the comparison of different developmental screening tools at 12 mo against the gold standard Developmental Assessment Scale for Indian Infants (DASII). At risk baby clinic of CDC, Kerala was established as a facility for follow up of NICU graduates from Sree Avittam Thirunal Hospital at 2, 4, 6, 8 and 12 mo corrected age and during each visit the mother is taught the CDC model early stimulation by developmental therapists and encouraged to continue to do the same at home. At 12 mo, assessment results of four simple developmental tools were compared with the gold standard DASII administered by a senior developmental therapist. Out of a total of 800 babies, outcome measurements at 12 mo were available for 604 infants. The prevalence of developmental delay using the screening tools, CDC grading for standing, Amiel Tison angles and DDST II (Denver II) gross motor were 24.8, 24 and 24.3% respectively and using DASII, a diagnostic tool (13.3%). Also the combination of Amiel Tison angles, CDC standing grading and DDST gross motor against DASII motor DQ had high specificity (94.15%) and negative predictive value (NPV) (70.18%) but with a very low sensitivity of 14.58% and low positive predictive value (PPV) of 53.85%. It was observed that a significant odds ratio for DASII mental deviation quotient (DQ) was seen for neonatal seizures (2.34) and low birth weight (1.49). The prevalence of developmental delay using the screening tools, CDC grading for standing, Amiel Tison angles and DDST II (Denver II) gross motor were 24.8, 24 and 24.3% respectively and together they had a high specificity, NPV and accuracy against DASII motor DQ as gold standard at one year assessment.

Objectives. We estimated the effect of community and school district resources on the identification of children with autistic disorder. Methods. Latent growth curve regression models were applied to school district–level data from one large state. Results. The rate of identification of autistic disorder increased on average by 1.0 child per 10000 per year (P<.001), with statistically significant district variation. After adjustment for district and community characteristics, each increase in decile of school revenue was associated with an increase of 0.16 per 10000 children identified with autistic disorder. The proportion of economically disadvantaged children per district was inversely associated with autistic disorder cases. Conclusions. District revenue was associated with higher proportions of children identified with autistic disorder at baseline and increasing rates of identification when measured longitudinally. Economically disadvantaged communities may need assistance to identify children with autistic spectrum disorders and other developmental delays that require attention. PMID:15623872

An epidemiological survey of Theileria annulata infection was undertaken in a cattle population in Rajshahi Division, Bangladesh. The local cattle breeds from the area (North Bengal Gray and Deshi) and crosses between the local breeds and Holstein cattle were predominantly screened. In total, 192 cattle serum samples were collected in two areas of Rajshahi Division, the Rajshahi District (n=147) and Natore District (n=45). The samples were screened with an enzyme-linked immunosorbent assay using T. annulata surface protein (TaSP) as the antigen. The seroprevalence was 80.0% (36/45) in Natore and 20.4% (30/147) in Rajshahi. A logistic regression analysis showed that the sampling location was significantly associated with seropositivity, whereas age, sex and breed were not. Although the logistic regression analysis did not show a linear dependence on age, we considered age-specific seroprevalence separately in the two districts. Seroprevalence did not differ significantly among age categories in the Natore District. In contrast, all the cattle <1 year old in the Rajshahi District were seronegative (11/11). Seroprevalence in the 1- and 2-year-old cattle was significantly lower in the Rajshahi District than in the Natore District. In the older age categories (3, 4 and >5 years), seroprevalence did not differ significantly between the Natore and Rajshahi Districts. These results suggest that the cattle in the Rajshahi District were sporadically exposed to T. annulata, whereas most cattle in the Natore District became infected during an early phase of life.

2015-01-01

Background Cervical cancer screening is a critical health service that is often unavailable to women in under-resourced settings. In order to expand access to this and other reproductive and primary health care services, a South African non-governmental organization established a van-based mobile clinic in two rural districts in South Africa. To inform policy and budgeting, we conducted a cost evaluation of this service delivery model. Methods The evaluation was retrospective (October 2012–September 2013 for one district and April–September 2013 for the second district) and conducted from a provider cost perspective. Services evaluated included cervical cancer screening, HIV counselling and testing, syndromic management of sexually transmitted infections (STIs), breast exams, provision of condoms, contraceptives, and general health education. Fixed costs, including vehicle purchase and conversion, equipment, operating costs and mobile clinic staffing, were collected from program records and public sector pricing information. The number of women accessing different services was multiplied by ingredients-based variable costs, reflecting the consumables required. All costs are reported in 2013 USD. Results Fixed costs accounted for most of the total annual costs of the mobile clinics (85% and 94% for the two districts); the largest contributor to annual fixed costs was staff salaries. Average costs per patient were driven by the total number of patients seen, at $46.09 and $76.03 for the two districts. Variable costs for Pap smears were higher than for other services provided, and some services, such as breast exams and STI and tuberculosis symptoms screening, had no marginal cost. Conclusions Staffing costs are the largest component of providing mobile health services to rural communities. Yet, in remote areas where patient volumes do not exceed nursing staff capacity, incorporating multiple services within a cervical cancer screening program is an approach to potentially expand access to health care without added costs.

Pregnancy and alcohol use: evidence and recommendations for prenatal care.

PubMed

Bailey, Beth A; Sokol, Robert J

2008-06-01

Pregnancy alcohol consumption has been linked to poor birth outcomes and long-term developmental problems. Despite this, a significant number of women drink during pregnancy. Although most prenatal care providers are asking women about alcohol use, validated screening tools are infrequently employed. Research has demonstrated that currently available screening methods and intervention techniques are effective in identifying and reducing pregnancy drinking. Implementing universal screening and appropriate intervention for pregnancy alcohol use should be a priority for prenatal care providers, as these efforts could substantially improve pregnancy, birth, and longer term developmental outcomes for those affected.

2018-01-01

Introduction In low-income and middle-income countries, it is estimated that one in every three preschool-age children are failing to meet cognitive or socioemotional developmental milestones. Thailand has implemented a universal national developmental screening programme (DSPM) for young children to enable detection of developmental disorders and early intervention that can improve child health outcomes. DSPM implementation is being hampered by low attendance at follow-up appointments when children fail the initial screening. Methods Action research, using qualitative methods was conducted with 19 caregivers, 5 health workers and 1 chief at two Health Promotion Hospitals to explore the factors affecting attendance at follow-up appointments. Transcripts and notes were analysed using descriptive content analysis. Findings were then discussed with 48 health workers, managers, researchers and policymakers. Results The high workload of health workers during busy vaccination clinics, and inadequate materials prevented clear communication with caregivers about the screening, how to stimulate child development and the screening result. Caregivers, particularly grandparents, had a lack of understanding about how to stimulate child development, and did not fully understand failed screening results. Caregivers felt blamed for not stimulating their child’s development, and were either worried that their child was severely disabled, or they did not believe the screening result and therefore questioned its usefulness. This led to a lack of attendance at follow-up appointments. Conclusion Task-sharing, mobile health (mhealth), community outreach and targeted interventions for grandparent caregivers might increase awareness about child development and screening, and allow health workers more time to communicate effectively. Sharing best practices, communication training and mentoring of DSPM workers coupled with mhealth job aids could also improve caregiver attendance at follow-up. Engagement of caregivers in understanding the barriers to attendance at follow-up and engagement of stakeholders in the design and implementation of interventions is important to ensure their effectiveness.

To document the experiences of the intervention given to children who attended the developmental therapy clinic of Child Development Centre (CDC) Kerala, a specialized clinic for providing developmental intervention/therapy for babies less than two years with developmental delay/disability. All the babies referred to this speciality clinic from developmental screening/evaluation clinics of CDC were registered in the clinic and re-evaluation was done using CDC grading for head holding, sitting, standing, Amiel Tison passive angles, and Trivandrum Developmental Screening Chart (TDSC) 0-2 y. Out of a total of 600 consecutive babies below 2 y with developmental delay/disability referred to developmental therapy clinic, on comparing the test results at enrollment and after 6 mo of intervention, a statistically significant reduction was observed (i) in the 2-4 mo age group with regard to abnormal TDSC (25.5%), (ii) in the 4-8 mo age group with regard to abnormal head holding grade (87.1%) and abnormal TDSC (19.4%), (iii) in the 8-12 mo age group, with regard to abnormal sitting grade (71.7%) and (iv) in the above 12 mo age group with regard to abnormal sitting grade (35.3%) and abnormal standing grade (78.8%). The experience of organizing the developmental intervention/therapy clinic at CDC Kerala has shown that therapy services by developmental therapists in a centre and supportive therapy by mother at home is useful in improving the developmental status of children with developmental delay.

Risk factor assessment to anticipate performance in the National Developmental Screening Test in children from a disadvantaged area.

Identifying children at risk of failing the National Developmental Screening Test by combining prevalences of children suspected of having inapparent developmental disorders (IDDs) and associated risk factors (RFs) would allow to save resources. 1. To estimate the prevalence of children suspected of having IDDs. 2. To identify associated RFs. 3. To assess three methods developed based on observed RFs and propose a pre-screening procedure. The National Developmental Screening Test was administered to 60 randomly selected children aged between 2 and 4 years old from a socioeconomically disadvantaged area from Puerto Madryn. Twenty-four biological and socioenvironmental outcome measures were assessed in order to identify potential RFs using bivariate and multivariate analyses. The likelihood of failing the screening test was estimated as follows: 1. a multivariate logistic regression model was developed; 2. a relationship was established between the number of RFs present in each child and the percentage of children who failed the test; 3. these two methods were combined. The prevalence of children suspected of having IDDs was 55.0% (95% confidence interval: 42.4%-67.6%). Six RFs were initially identified using the bivariate approach. Three of them (maternal education, number of health checkups and Z scores for height-for-age, and maternal age) were included in the logistic regression model, which has a greater explanatory power. The third method included in the assessment showed greater sensitivity and specificity (85% and 79%, respectively). The estimated prevalence of children suspected of having IDDs was four times higher than the national standards. Seven RFs were identified. Combining the analysis of risk factor accumulation and a multivariate model provides a firm basis for developing a sensitive, specific and practical pre-screening procedure for socioeconomically disadvantaged areas.

An examination of social interaction profiles based on the factors measured by the screen for social interaction.

Mahoney, Emery B; Breitborde, Nicholas J K; Leone, Sarah L; Ghuman, Jaswinder Kaur

2014-10-01

Deficits in the capacity to engage in social interactions are a core deficit associated with Autistic Disorder (AD) and Pervasive Developmental Disorder-Not Otherwise Specified (PDD-NOS). These deficits emerge at a young age, making screening for social interaction deficits and interventions targeted at improving capacity in this area important for early identification and intervention. Screening and early intervention efforts are particularly important given the poor short and long term outcomes for children with Autism Spectrum Disorders (ASDs) who experience social interaction deficits. The Screen for Social Interaction (SSI) is a well-validated screening measure that examines a child's capacity for social interaction using a developmental approach. The present study identified four underlying factors measured by the SSI, namely, Connection with Caregiver, Interaction/Imagination, Social Approach/Interest, and Agreeable Nature. The resulting factors were utilized to compare social interaction profiles across groups of children with AD, PDD-NOS, children with non-ASD developmental and/or psychiatric conditions and typically developing children. The results indicate that children with AD and those with PDD-NOS had similar social interaction profiles, but were able to be distinguished from typically developing children on every factor and were able to be distinguished from children with non-ASD psychiatric conditions on every factor except the Connection with Caregiver factor. In addition, children with non-ASD developmental and/or psychiatric conditions could be distinguished from typically developing children on the Connection with Caregiver factor and the Social Approach/Interest factor. These findings have implications for screening and intervention for children with ASDs and non-ASD psychiatric conditions. Copyright © 2014 Elsevier Ltd. All rights reserved.

Exploring barriers to the delivery of cervical cancer screening and early treatment services in Malawi: some views from service providers

Background Cervical cancer is the most common reproductive health cancer in Malawi. In most cases, women report to health facilities when the disease is in its advanced stage. In this study, we investigate service providers’ perceptions about barriers for women to access cervical cancer screening and early treatment services in Malawi. Methods We conducted in-depth interviews with 13 district coordinators and 40 service providers of cervical cancer screening and early treatment services in 13 districts in Malawi. The study was conducted in 2012. The district coordinators helped the research team identify the health facilities which were providing cervical cancer screening and early treatment services. Results Almost all informants reported that cervical cancer was a major public health problem in their districts and that prevention efforts for this disease were being implemented. They were aware of the test and treat approach using visual inspection with acetic acid (VIA). They, however, said that the delivery of cervical cancer screening and early treatment services was compromised because of factors such as gross shortage of staff, lack of equipment and supplies, the lack of supportive supervision, and the use of male service providers. Informants added that the lack of awareness about the disease among community members, long distances to health facilities, the lack of involvement of husbands, and prevailing misperceptions about the disease (eg, that it is caused by the exposure to the VIA process) affect the uptake of these services. Conclusion While progress has been made in the provision of cervical cancer screening and early treatment services in Malawi, a number of factors affect service delivery and uptake. There is a need to continue creating awareness among community members including husbands and also addressing identified barriers such as shortage of staff and supplies in order to improve uptake of services.

The incidence of language delay in Chinese preschool children was studied by a stratified proportional sampling of all 3 year olds in Hong Kong. The Developmental Language Screening Scale (DLSS) devised for use with Cantonese speaking children was used to identify children with language delay. Of 855 children sampled in the stage I screening procedure, 4%, 2.8% and 3.3% were identified as having delay in verbal comprehension, expression or both respectively. The stage II clinical diagnostic study included a randomly selected group of children screened in stage I with or without any associated behavioural problem. Among these, 3.4% were identified as having a language delay using the Reynell Language Developmental Scale (RDLS) with a criterion of language age of less than or equal to two-thirds of the chronological age; 3% had specific language delay using the criteria of language age less than or equal to two-thirds the chronological age and developmental age more than or equal to two-thirds the chronological age. More boys were found to have language delay, although this was not statistically significant.

Care for women with developmental disabilities requires special consideration for unique needs related to their cognitive and physical abilities. These women and their caregivers require more support and guidance during reproductive health care. We review the literature and provide expert opinion surrounding gynecological issues for women with developmental disabilities to support healthcare providers better understand and care for this population. Women with developmental disabilities are more vulnerable to abuse and experience poorer gynecological healthcare outcomes. Many women with developmental disabilities are fertile and participate in sexual activity without adequate knowledge. They are at higher risk of pregnancy and birth complications. They are less likely to receive appropriate preventive screening. The review highlights important issues and practice suggestions related to the reproductive health care of women with developmental disabilities. Topics include clinic visits, menstruation, sexuality, sexual abuse, sexual health education, contraception, sexually transmitted infections, pregnancy, labor and delivery, and cancer screening/prevention. We emphasize the need for an individualized, comprehensive approach for these patients and review perceived and actual barriers to care. More education is needed on the aforementioned topics for women with developmental disabilities, their caregivers, and their providers.

Are overreferrals on developmental screening tests really a problem?

PubMed

Glascoe, F P

2001-01-01

Developmental screening tests, even those meeting standards for screening test accuracy, produce numerous false-positive results for 15% to 30% of children. This is thought to produce unnecessary referrals for diagnostic testing or special services and increase the cost of screening programs. To explore whether children who pass screening tests differ in important ways from those who do not and to determine whether children overreferred for testing benefit from the scrutiny of diagnostic testing and treatment planning. Subjects were a national sample of 512 parents and their children (age range of the children, 7 months to 8 years) who participated in validation studies of various screening tests. Psychological examiners adhering to standardized directions obtained informed consent and administered at least 2 developmental screening measures (the Brigance Screens, the Battelle Developmental Inventory Screening Test, the Denver-II, and the Parents' Evaluations of Developmental Status) and a concurrent battery of diagnostic measures, including tests of intelligence, language, and academic achievement (for children aged 2(1/2) years and older). The performance on diagnostic measures of children who failed screening but were not found to have a disability (false positives) was compared with that of children who passed screening and did not have a disability on diagnostic testing (true negatives). Children with false-positive scores performed significantly (P<.001) lower on diagnostic measures than did children with true-negative scores. The false-positive group had scores in adaptive behavior, language, intelligence, and academic achievement that were 9 to 14 points lower than the scores of those in the true-negative group. When viewing the likelihood of scoring below the 25th percentile on diagnostic measures, children with false-positive scores had a relative risk of 2.6 in adaptive behavior (95% confidence interval [CI], 1.67-4.21), 3.1 in language skills (95% CI, 1.90-5.20), 6.7 on intelligence tests (95% CI, 3.28-13.50), and 4.9 on academic measures (95% CI, 2.61-9.28). Overall, 151 (70%) of the children with false-positive results scored below the 25th percentile on 1 or more diagnostic measures (the point at which most children have difficulty benefiting from typical classroom instruction) in contrast with 64 (29%) of the children with true-negative scores (odds ratio, 5.6; 95% CI, 3.73-8.49). Children with false-positive scores were also more likely to be nonwhite and to have parents who had not graduated from high school. Performance differences between children with true-negative scores and children with false-positive scores continued to be significant (P<.001) even after adjusting for sociodemographic differences between groups. Children overreferred for diagnostic testing by developmental screens perform substantially lower than children with true-negative scores on measures of intelligence, language, and academic achievement-the 3 best predictors of school success. These children also carry more psychosocial risk factors, such as limited parental education and minority status. Thus, children with false-positive screening results are an at-risk group for whom diagnostic testing may not be an unnecessary expense but rather a beneficial and needed service that can help focus intervention efforts. Although such testing will not indicate a need for special education placement, it can be useful in identifying children's needs for other programs known to improve language, cognitive, and academic skills, such as Head Start, Title I services, tutoring, private speech-language therapy, and quality day care.

Examining role forces and resources available to new teachers is crucial to understanding how teachers use and expand cultural, social, and symbolic resources and how they engage teaching for social justice and caring in urban science education. This critical narrative inquiry explores three levels of story. First, the narratives explore my role as a district science staff developer and my efforts to leverage district resources to improve students' opportunities to learn science. Second, the narratives explore the ways in which a novice science teacher, Tina, navigated role forces and the aesthetic|authentic caring dialectic in a high poverty, urban school. A third level of narrative draws on sociological theories of human interaction to explore role forces and how they shaped Tina's developmental trajectory. I describe how Tina expanded cultural, social, and symbolic resources to enact her teaching role.

Hearing-impaired children who are identified early and appropriately managed have improved outcomes in speech, language, cognitive and social development. Enhanced parental awareness of their child's hearing disability, behavioral, developmental and psychosocial limitations is essential to sustaining timely detection and appropriate intervention. Additionally, availability of services for diagnosis, treatment and habilitation would improve the demand for pedaudiological care in this community. To describe level of parental awareness of childhood HI and the pattern of access to and utilization of ambulatory care services. Thirty-three parents of lower primary school-going children who failed audiometric screening from sampled schools in Kisumu district, western Kenya. First person to detect HI, age of child at first suspicion of HI, source of ambulatory health care and use of the health care facilities. The prevalence of HI was 2.48%. Most parents/guardians (69.7%) were aware of their child's hearing impairment. Of these, 63.6% were first to detect HI in the pupils, while 30.3% were detected by screen. Most children (57.2%) were first recognized with (HI) after age 2 years. The mean age at identification was 5.5 years. The median travel distance to the preferred health care facility was 2 km (IQR 1-2.5). Parents seldom sought or lacked help for their hearing-impaired children. Of 27.3% who asked for hearing assessment, 9.1% received some counsel on HI and 12.1% received medication, one (3%) was referred for audiological assessment and none used a hearing aid. Use of health facilities for maternal care was (65.7%) and immunization (62.9%). Despite adequate parental awareness of chronic childhood disability, health facilities were underutilized. This indicates the need to further stimulate and maintain a desirable level of uptake of services for diagnosis, treatment and habilitation of childhood HI, while sustaining delivery of effective and acceptable high quality paediatric care.

To develop and validate a simple screening tool for identifying developmental delay among children of 0-6 y of age in the community. The 51-items of Trivandrum Development Screening Chart for children of 0-6 y [TDSC (0-6 y)], were carefully prepared from the norms in various existing developmental charts/scales, by experts keeping in mind the face validity and content validity. The criterion validity was assessed in a community sample of 1,183 children of 0-6 y with a mean age of 35.38 mo (SD of 19.25) including 597 (50.46%) boys and 586 (49.54%) girls. TDSC (0-6 y) was validated against Denver Developmental Screening Test (DDST) as the 'Reference Standard'. When one item delay in TDSC (0-6 y) was considered as 'TDSC delay' (test positive), the sensitivity and specificity of TDSC (0-6 y) was found to be 84.62% (95% CI: 71.92-93.12) and 90.8% (95% CI: 88.97-92.43) respectively with a Negative Predictive Value of 99.23% (95% CI: 98.48-99.67) and LR (negative) of 0.17(95% CI: 0.09-0.32). The test-retest and inter-rater reliability [an interclass correlation (ICC) of 0.77 for test-retest and ICC of 0.97 for inter-rater] were good and acceptable. TDSC (0-6 y) is a simple, reliable and valid screening tool for use in the community to identify children between 0 and 6 y with developmental delay, enabling early intervention practices.

Objective: To evaluate the reliability and validity of warning signs checklist developed by the National Health and Family Planning Commission of the People's Republic of China (NHFPC), so as to determine the screening effectiveness of warning signs on developmental problems of early childhood. Method: Stratified random sampling method was used to assess the reliability and validity of checklist of warning sign and 2 110 children 0 to 6 years of age(1 513 low-risk subjects and 597 high-risk subjects) were recruited from 11 provinces of China. The reliability evaluation for the warning signs included the test-retest reliability and interrater reliability. With the use of Age and Stage Questionnaire (ASQ) and Gesell Development Diagnosis Scale (GESELL) as the criterion scales, criterion validity was assessed by determining the correlation and consistency between the screening results of warning signs and the criterion scales. Result: In terms of the warning signs, the screening positive rates at different ages ranged from 10.8%(21/141) to 26.2%(51/137). The median (interquartile) testing time for each subject was 1(0.6) minute. Both the test-retest reliability and interrater reliability of warning signs reached 0.7 or above, indicating that the stability was good. In terms of validity assessment, there was remarkable consistency between ASQ and warning signs, with the Kappa value of 0.63. With the use of GESELL as criterion, it was determined that the sensitivity of warning signs in children with suspected developmental delay was 82.2%, and the specificity was 77.7%. The overall Youden index was 0.6. Conclusion: The reliability and validity of warning signs checklist for screening early childhood developmental problems have met the basic requirements of psychological screening scales, with the characteristics of short testing time and easy operation. Thus, this warning signs checklist can be used for screening psychological and behavioral problems of early childhood, especially in community settings.

To investigate the usefulness of MacArthur-Bates Communicative Development Inventories-Korean (M-B CDI-K) short form as a screening test in children with language developmental delay. From April 2010 to May 2012, a total of 87 patients visited the department of physical medicine and rehabilitation of National Health Insurance Service Ilsan Hospital with the complaint of language developmental delay and were enrolled in this study. All patients took M-B CDI-K short form and Sequenced Language Scale for Infants (SELSI) or Preschool Receptive-Expressive Language Scale (PRES) according to their age. The study group consisted of 58 male patients and 29 female patients and the mean age was 25.9 months. The diagnosis are global developmental delay in 26 patients, selective language impairment in 31 patients, articulation disorder in 7 patients, cerebral palsy in 8 patients, autism spectrum disorder in 4 patients, motor developmental delay in 4 patients, and others in 7 patients. Seventy-one patients are diagnosed with language developmental delay in SELSI or PRES and of them showed 69 patients a high risk in the M-B CDI-K short form. Sixteen patients are normal in SELSI or PRES and of them showed 14 patients non-high risk in the M-B CDI-K short form. The M-B CDI-K short form has 97.2% sensitivity, 87.5% specificity, a positive predictive value of 0.97, and a negative predictive value of 0.88. The M-B CDI-K short form has a high sensitivity and specificity so it is considered as an useful screening tool in children with language developmental delay. Additional researches targeting normal children will be continued to supply the specificity of the M-B CDI-K short form.

Lyimo, Frida S; Beran, Tanya N

Cervical cancer is an important public health problem worldwide, which comprises approximately 12% of all cancers in women. In Tanzania, the estimated incidence rate is 30 to 40 per 100,000 women, indicating a high disease burden. Cervical cancer screening is acknowledged as currently the most effective approach for cervical cancer control, and it is associated with reduced incidence and mortality from the disease. The aim of the study was to identify the most important factors related to the uptake of cervical cancer screening among women in a rural district of Tanzania. A cross sectional study was conducted with a sample of 354 women aged 18 to 69 years residing in Moshi Rural District. A multistage sampling technique was used to randomly select eligible women. A one-hour interview was conducted with each woman in her home. The 17 questions were modified from similar questions used in previous research. Less than one quarter (22.6%) of the participants had obtained cervical cancer screening. The following characteristics, when examined separately in relation to the uptake of cervical cancer screening service, were significant: husband approval of cervical cancer screening, women's level of education, women's knowledge of cervical cancer and its prevention, women's concerns about embarrassment and pain of screening, women's preference for the sex of health provider, and women's awareness of and distance to cervical cancer screening services. When examined simultaneously in a logistic regression, we found that only knowledge of cervical cancer and its prevention (OR = 8.90, 95%CI = 2.14-16.03) and distance to the facility which provides cervical cancer screening (OR = 3.98, 95%CI = 0.18-5.10) were significantly associated with screening uptake. Based on the study findings, three recommendations are made. First, information about cervical cancer must be presented to women. Second, public education of the disease must include specific information on how to prevent it as well as screening services available. Third, it is important to provide cervical cancer screening services within 5 km of where women reside.

Infant socioemotional development is often held under informal surveillance, but a formal screening program is needed to ensure systematic identification of developmental risk. Even when screening programs exist, they are often ineffective because health care professionals do not adhere to screening guidelines, resulting in low screening prevalence rates. To examine feasibility and acceptability of implementing universal screening for infant socioemotional problems with the Alarm Distress Baby Scale in primary care. The following questions were addressed: Is it possible to obtain acceptable screening prevalence rates within a 1-year period? How do the primary care workers (in this case, health visitors) experience using the instrument? Are attitudes toward using the instrument related to screening prevalence rates? A longitudinal mixed-method study (surveys, data from the health visitors' digital filing system, and qualitative coding of answers to open-ended questions) was undertaken. Health visitors in three of five districts of the City of Copenhagen, Denmark (N=79). We describe and evaluate the implementation process from the date the health visitors started the training on how to use the Alarm Distress Baby Scale to one year after they began using the instrument in practice. To monitor screening prevalence rates and adherence to guidelines, we used three data extractions (6, 9, and 12 months post-implementation) from the electronic filing system. Surveys including both quantitative and open-ended questions (pre- and post-implementation) were used to examine experiences with and attitudes towards the instrument. Descriptive and inferential statistical and qualitative content analyses were used. Screening prevalence rates increased during the first year: Six months after implementation 47% (n=405) of the children had been screened; 12 months after implementation 79% (n=789) of the children were screened (the same child was not counted more than once). Most (92%) of the health visitors reported that the instrument made a positive contribution to their work. The majority (81%) also reported that it posed a challenge in their daily work at least to some degree. The health visitors' attitudes (positive and negative) toward the Alarm Distress Baby Scale, measured 7 months post-implementation, significantly predicted screening prevalence rates 12 months post-implementation. Adding the Alarm Distress Baby Scale to an established surveillance program is feasible and accepTable Screening prevalence rates may be related to the primary care worker's attitude toward the instrument, i.e. successful implementation relies on an instrument that adds value to the work of the screener.

To determine the accuracy of various predictors of school problems, we conducted a 3-year prospective study of 1999 children who began school in the Niagara region of Ontario in 1980. During the year before school entry the parents gave a health, developmental and behavioural history during an interview with a community health nurse, and the children underwent vision and hearing screening tests and the Denver Developmental Screening Test (DDST). At the end of the 1980-81 school year the kindergarten teachers rated the children's learning problems. At the end of the 1982-83 school year the presence of school problems was ascertained, and the predictive accuracy of items from the preschool history and examination and of the kindergarten teachers' ratings was calculated. The health, developmental and behavioural history with or without the DDST was found to predict later school problems with acceptable accuracy. The kindergarten teachers' ratings gave slightly more accurate predictions. We conclude that in communities where prompt diagnostic evaluation and effective therapeutic or preventive help can be provided to children identified as being at high risk, health professionals may play a useful role in screening for future school problems.

Developmental delay and intellectual disability are significant medical and social problems which concern 1-3% of population. The etiology remains unknown in over half of the cases. To evaluate the efficiency of MLPA (Multiplex Ligation-dependent Probe Amplification) as a screening test in diagnosis of patients with developmental delay and/or intellectual disability. 313 MLPA tests were performed in 256 patients with developmental delay and/ or intellectual disability with unknown etiology. MLPA test was made after exclusion of genetic disorders possible to diagnose by dysmorphological examination or using specifi c genetic tests. Positive results were confirmed by FISH analysis with appropriate probes. Chromosomal microaberrations were identifi ed in 15 patients (4,8%): deletions of 1p36 in 4 cases, in one case deletion of 22q11.21, 22q13.33, SNRPN1, 4ptel, 6qtel, 7q11.23, 16ptel, 18qtel as well as one ca se of deletion 3ptel/duplication 15qtel; deletion 18qtel/duplication Xqtel, and also duplication 7q11.23. Detail clinical analysis was performed in patients with diagnosed microaberrations in MLPA test. The molecular MLPA test, screening for chromosomal microaberration syndromes, should be performed in each patient with developmental delay and/or intellectual disability of unknown etiology and normal cytogenetic analysis, even if congenital defects and positive familial history do not exist.

To describe benefits and problems with screening and addressing developmental and behavioral problems in primary care and using an online clinical process support system as a solution. Screening has been found to have various implementation barriers including time costs, accuracy, workflow and knowledge of tools. In addition, training of clinicians in dealing with identified issues is lacking. Patients disclose more to and prefer computerized screening. An online clinical process support system (CHADIS) shows promise in addressing these issues. Use of a comprehensive panel of online pre-visit screens; linked decision support to provide moment-of-care training; and post-visit activities and resources for patient-specific education, monitoring and care coordination is an efficient way to make the entire process of screening and follow up care feasible in primary care. CHADIS fulfills these requirements and provides Maintenance of Certification credit to physicians as well as added income for screening efforts.

The prevalence of Enterobius vermicularis infection among preschool children was reported to be low based on a 5-year screening program in Taipei City, Taiwan. The Taipei City government intended to terminate the E. vermicularis screening program among preschool children. Thus, we were entrusted with confirming whether pinworm infections among preschool children in Taipei City had truly declined. From each of 12 administrative districts 2-3 kindergartens were randomly selected for investigation. In total, 4,349 children were examined, of which 2,537 were boys and 1,812 were girls. The cellophane tape adhered to a glass slide was used, and all examinations were done by certified medical technologists. Results indicated that the overall prevalence rate of pinworm infections was 0.62% (27/4,349). Although the infection rate was higher among boys (0.67%, 17/2,537) than in girls (0.55%, 10/1,812), no significant difference was found (χ2 = 0.399, P = 0.62). According to the administrative district, the infection rate ranged from no positive cases of E. vermicularis infection in the Xinyi, Zhongzhen, and Wanhua Districts (0%; 0/299, 0/165, and 0/358, respectively), to 0.26% (1/131) in Songshan District, with the highest rate of 1.88% (7/373) in Wenshan District. Because the overall infection rate (0.62%, 27/4,349) in the present study was unchanged compared to that (0.40%, 197/49,541) previously reported in 2005, we propose that regular pinworm screening and treatment programs should be continued in some parts of Taipei City.

We evaluated 2-year neurodevelopmental outcomes in children with gastroschisis. We reviewed the records of children with gastroschisis treated between August 2001 and July 2008. Children discharged from the neonatal intensive care unit were referred to the state-sponsored Developmental Tracking Infant Progress Statewide (TIPS) program. We reviewed TIPS assessments performed before age 2 years. School districts evaluated children referred by TIPS and determined their eligibility for early intervention services. Poor outcomes were defined as scores of "failure" or "moderate/high risk" on the screening assessment or enrollment in early intervention services by 2 years. Children with gastroschisis were compared with case-matched nonsurgical, nonsyndromic children of similar gestational age and birth weight. One hundred five children were born with gastroschisis, and 46 were followed up with TIPS. There was no statistically significant difference in performance on screening assessments or in the rate of enrollment in early intervention services between the gastroschisis children and controls. Children born with gastroschisis have similar 2-year neurodevelopmental outcomes as nonsurgical, nonsyndromic neonatal intensive care unit children of similar gestational age and birth weight. Both groups of children have a higher rate of enrollment in early intervention than their healthy peers. These data suggest that neurodevelopmental outcomes in gastroschisis children are delayed secondary to prematurity rather than the presence of the surgical disease. Copyright © 2012 Elsevier Inc.

Cholangiocarcinoma (CCA) is a serious problem in Thailand, particularly in the northeastern and northern regions. Database of population at risk are need required for monitoring, surveillance, home health care, and home visit. Therefore, this study aimed to develop a geographic information system (GIS) database and Google map of the population at risk of CCA in Mueang Yang district, Nakhon Ratchasima province, northeastern Thailand during June to October 2015. Populations at risk were screened using the Korat CCA verbal screening test (KCVST). Software included Microsoft Excel, ArcGIS, and Google Maps. The secondary data included the point of villages, sub-district boundaries, district boundaries, point of hospital in Mueang Yang district, used for created the spatial databese. The populations at risk for CCA and opisthorchiasis were used to create an arttribute database. Data were tranfered to WGS84 UTM ZONE 48. After the conversion, all of the data were imported into Google Earth using online web pages www.earthpoint.us. Some 222 from a 4,800 population at risk for CCA constituted a high risk group. Geo-visual display available at following www.google.com/maps/d/u/0/ edit?mid=zPxtcHv_iDLo.kvPpxl5mAs90 and hl=th. Geo-visual display 5 layers including: layer 1, village location and number of the population at risk for CCA; layer 2, sub-district health promotion hospital in Mueang Yang district and number of opisthorchiasis; layer 3, sub-district district and the number of population at risk for CCA; layer 4, district hospital and the number of population at risk for CCA and number of opisthorchiasis; and layer 5, district and the number of population at risk for CCA and number of opisthorchiasis. This GIS database and Google map production process is suitable for further monitoring, surveillance, and home health care for CCA sufferers.

Few areas of medicine demonstrate such international divergence as child development screening and surveillance. Many countries have nationally mandated surveillance policies, but the content of programmes and mechanisms for delivery vary enormously. The cost of programmes is substantial but no economic evaluations have been carried out. We have critically examined the history, underlying philosophy, content and delivery of programmes for child development assessment in five countries with comprehensive publicly funded health services (Denmark, Finland, Norway, Scotland and Sweden). The specific focus of this article is on motor, social, emotional, behavioural and global cognitive functioning including language. Variations in developmental surveillance programmes are substantially explained by historical factors and gradual evolution although Scotland has undergone radical changes in approach. No elements of universal developmental assessment programmes meet World Health Organization screening criteria, although some assessments are configured as screening activities. The roles of doctors and nurses vary greatly by country as do the timing, content and likely costs of programmes. Inter-professional communication presents challenges to all the studied health services. No programme has evidence for improved health outcomes or cost effectiveness. Developmental surveillance programmes vary greatly and their structure appears to be driven by historical factors as much as by evidence. Consensus should be reached about which surveillance activities constitute screening, and the predictive validity of these components needs to be established and judged against World Health Organization screening criteria. Costs and consequences of specific programmes should be assessed, and the issue of inter-professional communication about children at remediable developmental risk should be prioritised.

Large-scale mutagenesis screens in the zebrafish employing the mutagen ENU have isolated several hundred mutant loci that represent putative developmental control genes. In order to realize the potential of such screens, systematic genetic mapping of the mutations is necessary. Here we report on a large-scale effort to map the mutations generated in mutagenesis screening at the Max Planck Institute for Developmental Biology by genome scanning with microsatellite markers. We have selected a set of microsatellite markers and developed methods and scoring criteria suitable for efficient, high-throughput genome scanning. We have used these methods to successfully obtain a rough map position for 319 mutant loci from the Tübingen I mutagenesis screen and subsequent screening of the mutant collection. For 277 of these the corresponding gene is not yet identified. Mapping was successful for 80 % of the tested loci. By comparing 21 mutation and gene positions of cloned mutations we have validated the correctness of our linkage group assignments and estimated the standard error of our map positions to be approximately 6 cM. By obtaining rough map positions for over 300 zebrafish loci with developmental phenotypes, we have generated a dataset that will be useful not only for cloning of the affected genes, but also to suggest allelism of mutations with similar phenotypes that will be identified in future screens. Furthermore this work validates the usefulness of our methodology for rapid, systematic and inexpensive microsatellite mapping of zebrafish mutations.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a common enzymatic disorder of the erythrocytes that affects 400 million people worldwide. We developed a PCR-reverse dot blot (RDB) assay to screen twenty genotypes of seventeen Chinese G6PD mutations and investigate the spectrum of G6PD deficiency mutations in Dongguan District, Guangdong Province, in southern China. The PCR-RDB assay consists of multiplex PCR amplification of seven fragments in the G6PD target sequence of wild-type and mutant genomic DNA samples followed by hybridization to a test strip containing allele-specific oligonucleotide probes. A total of 16,464 individuals were analyzed by a combination of phenotypic screening and genotypic detection using the PCR-RDB assay and DNA sequence analysis. The PCR-RDB assay had a detection rate of 98.1%, which was validated by direct sequencing in a blind study with 100% concordance. The G6PD deficiency incidence rate in Dongguan District is 4.08%. Thirty-two genotypes from 469 individuals were found. The two most common variants were c.1376G>T and c.1388G>A, followed by c.95A>G, c.871G>A, c.392G>T, and c.1024 C>T. In addition, two rare mutations (c.703C>A and c.406C>T) were detected by DNA sequencing analysis. In our study, 65 cases harbored the C1311T/IVS polymorphism and 67 cases were homozygote. The PCR-RDB assay we established is a reliable and effective method for screening G6PD mutations in the Chinese population. Data on the spectrum of mutations in the Dongguan District is beneficial to the clinical diagnosis and prevention of G6PD deficiency.

Screening is an important issue in medicine and is used to early identify unrecognised diseases in persons who are apparently in good health. Screening strongly relies on the concept of "normal values". Normal values are defined as values that are frequently observed in a population and usually range within certain statistical limits. Screening for obesity should start early as the prevalence of obesity consolidates already at early school age. Though widely practiced, measuring BMI is not the ultimate solution for detecting obesity. Children with high BMI may be "robust" in skeletal dimensions. Assessing skeletal robustness and in particularly assessing developmental tempo in adolescents are also important issues in health screening. Yet, in spite of the necessity of screening investigations, appropriate reference values are often missing. Meanwhile, new concepts of growth diagrams have been developed. Stage line diagrams are useful for tracking developmental processes over time. Functional data analyses have efficiently been used for analysing longitudinal growth in height and assessing the tempo of maturation. Convenient low-cost statistics have also been developed for generating synthetic national references.

Translations of Developmental Screening Instruments: An Evidence Map of Available Research.

2015-01-01

Children whose parents do not speak English experience significant disparities in the identification of developmental delays and disorders; however, little is known about the availability and validity of translations of developmental screeners. The goal was to create a map of the scientific evidence regarding translations of the 9 Academy of Pediatrics-recommended screening instruments into languages other than English. The authors conducted a systematic search of Medline and PsycINFO, references of identified articles, publishers' Web sites, and official manuals. Through evidence mapping, a new methodology supported by AHRQ and the Cochrane Collaboration, the authors documented the extent and distribution of published evidence supporting translations of developmental screeners. Data extraction focused on 3 steps of the translation and validation process: (1) translation methods used, (2) collection of normative data in the target language, and (3) evidence for reliability and validity. The authors identified 63 distinct translations among the 9 screeners, of which 44 had supporting evidence published in peer-reviewed sources. Of the 63 translations, 35 had at least some published evidence regarding translation methods used, 28 involving normative data, and 32 regarding reliability and/or construct validity. One-third of the translations found were of the Denver Developmental Screening Test. Specific methods used varied greatly across screeners, as did the level of detail with which results were reported. Few developmental screeners have been translated into many languages. Evidence map of the authors demonstrates considerable variation in both the amount and the comprehensiveness of information available about translated instruments. Informal guidelines exist for conducting translation of psychometric instruments but not for documentation of this process. The authors propose that uniform guidelines be established for reporting translation research in peer-reviewed journals, similar to those for clinical trials and studies of diagnostic accuracy.

Parental perceptions of technology and technology-focused parenting: Associations with youth screen time

Sanders, Wesley; Parent, Justin; Forehand, Rex; Sullivan, Alexandra D.W.; Jones, Deborah J.

2016-01-01

In the present study we propose a model linking parental perceptions of technology to technology-related parenting strategies to youth screen time, and, finally, to internalizing and externalizing problem behaviors. Participants were 615 parents drawn from three community samples of families with children across three developmental stages: young childhood, middle childhood, and adolescence. The model was tested at each stage with the strongest support emerging in the young childhood sample. One component of parental perceptions of technology, perceived efficacy, was related to technology-related parenting strategies across developmental stages. However, the association of these strategies to child screen time and, in turn, problem behaviors, diminished as children increased in age. Implications for intervention are considered.

2016-04-23

Transfusion-transmitted malaria (TTM) is a risk of transfusion that has not been well described in malaria endemic regions. The risk of the recipient getting malaria is related to the prevalence of malaria in the blood donors. There is however little information on the prevalence of malaria among donors in Akatsi district of Ghana. Further, the knowledge and practices of healthcare workers to TTM is unknown. The study was undertaken to determine the prevalence of malaria parasite infection among blood donors and to evaluate the knowledge and practices of healthcare workers to TTM in the Akatsi district of Ghana. The study was conducted at Akatsi South District Hospital between May and August 2014. To screen for Plasmodium falciparum, 5 µl of capillary blood was obtained by finger prick from 200 participants (100 donors and 100 healthy controls). Plasmodium falciparum screening was done using CareStart™ Malaria Antigen kit. To obtain information regarding TTM knowledge and practices, questionnaires were completed by 100 health workers including nurses, doctors and laboratory staff. The prevalence of P. falciparum was the same (10 %) in both donors and controls. All those who were malaria RDT positive were aged 15-25 years. Out of the 100 healthcare workers (31 males and 69 females) surveyed, 45 % of respondents (45/100) had never heard of transfusion-transmitted malaria. Almost all respondents (91 %) had not attended any lecture/seminar/workshop on blood transfusion in the past 12 months. There were 44 respondents (44 %) who wrongly said malaria was being screened for prior to transfusion in their hospital. However, 98.2 % (54/55) of those who had heard about TTM rightly stated that TTM can be prevented. The prevalence of P. falciparum parasitaemia is 10 % in healthy blood donors in the Akatsi district and represents a risk for TTM though the extent of this risk is unclear. Knowledge about TTM in healthcare workers in the district is low. Continuous education and in-service training may be a means to improve TTM knowledge and preventive practices by the health workers in the district.

Beginning school is an important milestone for children. Children's readiness for school involves cognitive, physical, and emotional development. Certain school programs allow children to start first grade after 66 months of age, together with 72 month-old children. In order to estimate school readiness, we screened children before starting first grade and compared their school performance according to their age and socio-demographic characteristics. Marmara School Readiness, Denver II developmental screening, and language assessment tests were applied. Language delays were more frequent and school readiness test scores were lower in the younger group compared to older children. However, school achievement did not differ between the two age groups. Preschool education, parental income and education affected performance in most tests. Preschool screening seems effective in detecting children with lower than average developmental skills, and the school system may provide a practical opportunity for providing support to those children.

Youth Screen Time and Behavioral Health Problems: The Role of Sleep Duration and Disturbances.

2016-05-01

The purpose of this study was to examine the indirect effect of youth screen time (e.g., television, computers, smartphones, video games, and tablets) on behavioral health problems (i.e., internalizing, externalizing, and peer problems) through sleep duration and disturbances. The authors assessed a community sample of parents with a child in one of the following three developmental stages: young childhood (3-7 yrs; N = 209), middle childhood (8-12 yrs; N = 202), and adolescence (13-17 yrs; N = 210). Path analysis was used to test the hypothesized indirect effect model. Findings indicated that, regardless of the developmental stage of the youth, higher levels of youth screen time were associated with more sleep disturbances, which, in turn, were linked to higher levels of youth behavioral health problems. Children who have increased screen time are more likely to have poor sleep quality and problem behaviors.

Evolutionary thinking continues to challenge our views on health and disease. Yet, there is a communication gap between evolutionary biologists and toxicologists in recognizing the connections among developmental pathways, high-throughput screening, and birth defects in humans. To increase our capability in identifying potential developmental toxicants in humans, we propose to apply evolutionary genetics to improve the experimental design and data interpretation with various in vitro and whole-organism models. We review five molecular systems of stress response and update 18 consensual cell-cell signaling pathways that are the hallmark for early development, organogenesis, and differentiation; and revisit the principles of teratology in light of recent advances in high-throughput screening, big data techniques, and systems toxicology. Multiscale systems modeling plays an integral role in the evolutionary approach to cross-species extrapolation. Phylogenetic analysis and comparative bioinformatics are both valuable tools in identifying and validating the molecular initiating events that account for adverse developmental outcomes in humans. The discordance of susceptibility between test species and humans (ontogeny) reflects their differences in evolutionary history (phylogeny). This synthesis not only can lead to novel applications in developmental toxicity and risk assessment, but also can pave the way for applying an evo-devo perspective to the study of developmental origins of health and disease.

2008-04-01

We examined the effectiveness of a teacher-based rating scale called the teacher estimation of activity form (TEAF) to screen for developmental coordination disorder (DCD) in children. A random selection of 15 of 75 schools from the District School Board of Niagara in Ontario, Canada was chosen for this study. Every consented child in Grade 4 (n=502) was evaluated for probable DCD (pDCD) in school using the short form Bruininks-Oseretsky test of motor proficiency (BOTMP-SF). Each student also completed the children's self perceptions of adequacy in and predilection toward physical activity (CSAPPA) scale, participation questionnaire, and Léger 20-meter shuttle run, and had their height and weight measured. The 27 children (5.1%) who scored below the 5th percentile on BOTMP-SF were designated as pDCD cases and the 475 children who scored above the 5th percentile served as controls. Results showed that mean TEAF scores were significantly lower for pDCD children than controls (p<.001). Total TEAF scores ranging from 28 to 32 were preferred in maintaining good sensitivity (.74, 95% CI=.55-.87 to .85, 95% CI=.68-.94). The area under the ROC curve was .77 (95% CI, .68-.86) for the TEAF total score, and some individual items performed approximately as well as the full scale. The TEAF was positively correlated with measures of physical activity and fitness. The TEAF appears to be an effective tool in screening for DCD, particularly in a population setting. Considering the brevity of the TEAF and the discriminative power of individual items, this instrument would be effective in an abbreviated version.

Healthy social-emotional development in early childhood is important as an indicator of general well-being and for positive outcome in later childhood. Therefore, screening for potential social emotional problems is valuable. Accurate, usable, and affordable screening tools have been especially difficult to develop. The cross cultural validity of a screening instrument should be assessed. The aim of the current study was to investigate the reliability and validity of the Greenspan social-emotional growth chart (GSEGC) in Israeli children of three diagnostic groups: (1) Autistic spectrum disorder (ASD) (2) Developmental language disorder (DLD) and (3) Developmental motor delay (DMD). An internal reliability of alpha of 0.95 for the GSEGC standardized for age score and of 0.78 for the sensory processing sub scores was found. A confirmatory factor analysis (CFA) using a 5-factor model confirmed an acceptable fit. Positive (62.86%) and negative (94.73%) predictive values also support the clinical usefulness of the GSEGC in identifying children at low risk for ASD. The GSEGC appears to be a promising tool for the screening of social emotional problems in early childhood. Further studies in different cultures are warranted. Copyright © 2016 Elsevier Ltd.

Urease pretreatment-gas chromatography-mass spectrometry (UP-GC-MS) has become a valuable tool in the field of metabolome research, including analysis of inborn errors of metabolism (IEMs) and acquired metabolic disturbances secondary to nutrition or drugs. This research aims to screen IEMs in Chinese patients and to explore the cause of neural tube defects (NTDs), a congenital malformation very common in North China. Urine samples from 618 patients at high risk of IEMs in China were collected, and UP-GC-MS was performed in the selective screening. Urinary methylmalonate (MMA) levels in pregnancy with and without NTDs fetus, respectively, at Luliang district, a countryside region with NTDs incidence 227/10,000, Shanxi Province, North China, were analyzed by GC-MS-selective ion monitoring, and compared with that from control region. Among the 618 patients, 22 kinds and 59 cases of IEM were found. Methylmalonic aciduria (MMAuria) is on top of the list, followed by neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD), phenylketonuria (PKU), multiple carboxylase deficiency (MCD), etc. Satisfactory therapeutic effects have been achieved in patients such as NICCD, MCD, and galactosemia. At Luliang district, urinary MMA levels in pregnancy, no matter NTDs-affected or unaffected, are both significantly (P<0.01) higher than that in normal control, while serum B(12) levels in NTDs-affected pregnancy are significantly lower than that both in NTDs-unaffected group (P<0.01) and in normal control (P<0.01). Furthermore, B(12) <52.5 pmol/L is associated with a 7.78-fold increased NTDs risk (P<0.01) at Luliang district. Selective screening for IEMs by UP-GC-MS provides valuable evidences for the diagnosis of IEMs. MMAuria secondary to B(12) deficiency is quite common at Luliang district, suggesting B(12) deficiency is involved in the development of NTDs in the specific population. This metabolome research by UP-GC-MS provides valuable epidemiological information that helps to understand the prevalence and the possible intervention strategy of NTDs and IEMs, especially in Chinese population.

Psychiatric diagnostic screening of social maladaptive behaviour in children with mild intellectual disability: differentiating disordered attachment and pervasive developmental disorder behaviour.

PubMed

Giltaij, H P; Sterkenburg, P S; Schuengel, C

2015-02-01

Children with intellectual disability (ID) are at risk for maladaptive development of social relatedness. Controversy exists whether Pervasive Developmental Disorder (PDD) takes precedence over disordered attachment for describing maladaptive social behaviour. The aim of this study was to assess the prevalence of disordered attachment symptoms in children with ID referred for mental health diagnosis, and to study the potential diagnostic overlap between symptoms of disordered attachment and PDD symptoms. Children (n = 102) in the age of 5-11 with IDs (borderline or mild; IQ 50-85) referred for psychiatric consultation were recruited. Parents were administered a screening interview for disturbances of attachment and teachers were administered a screening questionnaire for PDD. Behavioural symptoms of disordered attachment were reported for 42%* of the children, with 16%* showing symptoms of inhibited and 37%* showing symptoms of disinhibited attachment disorder. In 11% both types of symptoms were noted. Attachment disorder symptoms were not significantly associated with gender, ethnic background or age. Positive screening for PDD occurred for 27%. Positive screening for PDD was not significantly associated with symptoms of attachment disorder. Among children with ID referred for psychiatric consultation, Reactive Attachment Disorder (RAD) and PDD symptoms were both highly prevalent. RAD and PDD symptoms appear as distinct, but sometimes comorbid, forms of aberrant social relatedness.

Havercamp, Susan M; Scandlin, Donna; Roth, Marcia

2004-01-01

The purposes of this study were (1) to identify disparities between adults with developmental disabilities and non-disabled adults in health and medical care, and (2) to compare this pattern of disparities to the pattern of disparities between adults with other disabilities and adults without disabilities. The authors compared data on health status, health risk behaviors, chronic health conditions, and utilization of medical care across three groups of adults: No Disability, Disability, and Developmental Disability. Data sources were the 2001 North Carolina Behavioral Risk Factor Surveillance System and the North Carolina National Core Indicators survey. Adults with developmental disabilities were more likely to lead sedentary lifestyles and seven times as likely to report inadequate emotional support, compared with adults without disabilities. Adults with disabilities and developmental disabilities were significantly more likely to report being in fair or poor health than adults without disabilities. Similar rates of tobacco use and overweight/obesity were reported. Adults with developmental disabilities had a similar or greater risk of having four of five chronic health conditions compared with non-disabled adults. Significant medical care utilization disparities were found for breast and cervical cancer screening as well as for oral health care. Adults with developmental disabilities presented a unique risk for inadequate emotional support and low utilization of breast and cervical cancer screenings. Significant disparities in health and medical care utilization were found for adults with developmental disabilities relative to non-disabled adults. The National Core Indicators protocol offers a sound methodology to gather much-needed surveillance information on the health status, health risk behaviors, and medical care utilization of adults with developmental disabilities. Health promotion efforts must be specifically designed for this population.

A review is presented of the use of developmental toxicity testing in the United States and international regulatory assessment of human health risks associated with exposures to pharmaceuticals (human and veterinary), chemicals (agricultural, industrial, and environmental), food additives, cosmetics, and consumer products. Developmental toxicology data are used for prioritization and screening of pharmaceuticals and chemicals, for evaluating and labeling of pharmaceuticals, and for characterizing hazards and risk of exposures to industrial and environmental chemicals. The in vivo study designs utilized in hazard characterization and dose-response assessment for developmental outcomes have not changed substantially over the past 30 years and have served the process well. Now there are opportunities to incorporate new technologies and approaches to testing into the existing assessment paradigm, or to apply innovative approaches to various aspects of risk assessment. Developmental toxicology testing can be enhanced by the refinement or replacement of traditional in vivo protocols, including through the use of in vitro assays, studies conducted in alternative nonmammalian species, the application of new technologies, and the use of in silico models. Potential benefits to the current regulatory process include the ability to screen large numbers of chemicals quickly, with the commitment of fewer resources than traditional toxicology studies, and to refine the risk assessment process through an enhanced understanding of the mechanisms of developmental toxicity and their relevance to potential human risk. As the testing paradigm evolves, the ability to use developmental toxicology data to meet diverse critical regulatory needs must be retained. © 2011 Wiley Periodicals, Inc.

The Gilliam Autism Rating Scale-Second Edition (GARS-2) is a widely used screening instrument that assists in the identification and diagnosis of autism. The purpose of this study was to examine the factor structure, internal consistency, and screening sensitivity of the GARS-2 using ratings from special education teaching staff for a sample of 240 individuals with autism or other significant developmental disabilities. Exploratory factor analysis yielded a correlated three-factor solution similar to that found in 2005 by Lecavalier for the original GARS. Though the three factors appeared to be reasonably consistent with the intended constructs of the three GARS-2 subscales, the analysis indicated that more than a third of the GARS-2 items were assigned to the wrong subscale. Internal consistency estimates met or exceeded standards for screening and were generally higher than those in previous studies. Screening sensitivity was .65 and specificity was .81 for the Autism Index using a cut score of 85. Based on these findings, recommendations are made for instrument revision. PMID:26981279

Hearing impairment is one of the most critical sensory impairments with significant social and psychological consequences. Evidence-based, standardized national guidelines are needed for professionals to screen for hearing impairment during the neonatal period. The meeting on formulation of national consensus guidelines on developmental disorders was organized by Indian Academy of Pediatrics in Mumbai, on 18th and 19th December, 2015. The invited experts included Pediatricians, Developmental Pediatricians, Pediatric Neurologists and Clinical Psychologists. The participants framed guidelines after extensive discussions. To provide guidelines on newborn hearing screening in India. The first screening should be conducted before the neonate's discharge from the hospital - if it 'fails', then it should be repeated after four weeks, or at first immunization visit. If it 'fails' again, then Auditory Brainstem Response (ABR) audiometry should be conducted. All babies admitted to intensive care unit should be screened via ABR. All babies with abnormal ABR should undergo detailed evaluation, hearing aid fitting and auditory rehabilitation, before six months of age. The goal is to screen newborn babies before one month of age, diagnose hearing loss before three months of age and start intervention before six months of age.

Functional Conservation of the Glide/Gcm Regulatory Network Controlling Glia, Hemocyte, and Tendon Cell Differentiation in Drosophila

High-throughput screens allow us to understand how transcription factors trigger developmental processes, including cell specification. A major challenge is identification of their binding sites because feedback loops and homeostatic interactions may mask the direct impact of those factors in transcriptome analyses. Moreover, this approach dissects the downstream signaling cascades and facilitates identification of conserved transcriptional programs. Here we show the results and the validation of a DNA adenine methyltransferase identification (DamID) genome-wide screen that identifies the direct targets of Glide/Gcm, a potent transcription factor that controls glia, hemocyte, and tendon cell differentiation in Drosophila. The screen identifies many genes that had not been previously associated with Glide/Gcm and highlights three major signaling pathways interacting with Glide/Gcm: Notch, Hedgehog, and JAK/STAT, which all involve feedback loops. Furthermore, the screen identifies effector molecules that are necessary for cell-cell interactions during late developmental processes and/or in ontogeny. Typically, immunoglobulin (Ig) domain–containing proteins control cell adhesion and axonal navigation. This shows that early and transiently expressed fate determinants not only control other transcription factors that, in turn, implement a specific developmental program but also directly affect late developmental events and cell function. Finally, while the mammalian genome contains two orthologous Gcm genes, their function has been demonstrated in vertebrate-specific tissues, placenta, and parathyroid glands, begging questions on the evolutionary conservation of the Gcm cascade in higher organisms. Here we provide the first evidence for the conservation of Gcm direct targets in humans. In sum, this work uncovers novel aspects of cell specification and sets the basis for further understanding of the role of conserved Gcm gene regulatory cascades. PMID:26567182

Background Identifying disability early in life confers long-term benefits for children. The Taipei City Child Development Screening tool, second version (Taipei II) provides checklists for 13 child age groups from 4 months to 6 years. However, the usability of a text-based screening tool largely depends on the literacy level and logical reasoning ability of the caregivers, as well as language barriers caused by increasing numbers of immigrants. Objective The objectives of this study were to (1) design and develop a Web-based multimedia version of the current Taipei II developmental screening tool, and (2) investigate the measurement equivalence of this multimedia version to the original paper-based version. Methods To develop the multimedia version of Taipei II, a team of experts created illustrations, translations, and dubbing of the original checklists. The developmental screening test was administered to a total of 390 primary caregivers of children aged between 4 months and 6 years. Results Psychometric testing revealed excellent agreement between the paper and multimedia versions of Taipei II. Good to excellent reliabilities were demonstrated for all age groups for both the cross-mode similarity (mode intraclass correlation range 0.85-0.96) and the test-retest reliability (r=.93). Regarding the usability, the mean score was 4.80 (SD 0.03), indicating that users were satisfied with their multimedia website experience. Conclusions The multimedia tool produced essentially equivalent results to the paper-based tool. In addition, it had numerous advantages, such as it can facilitate active participation and promote early screening of target populations.

OBJECTIVE--To see if there were differences in referral rates and abnormalities detected from two areas that were operating different preschool vision screening programmes. DESIGN--Cohort study using case notes of referrals. SETTING--Community based secondary referral centres in the county of Avon. PATIENTS--263 referrals from a child population of 7105 in Southmead district, an area that used orthoptists as primary vision screeners; 111 referrals from a child population of 2977 in Weston-super-Mare, an area that used clinical medical officers for screening. MAIN OUTCOME MEASURES--Amblyopia and squint detection rates, together with false positive referral rates. RESULTS--The amblyopia detection rate in Southmead district was significantly higher than in Weston-super-Mare (11/1000 children v 5/1000), as was the detection rate of squint (11/1000 v 3/1000). However, the false positive referral rate from Southmead was significantly lower than that from Weston-super-Mare (9/1000 v 23/1000). CONCLUSION--Preschool vision screening using orthoptists as primary screeners offers a more effective method of detecting visual abnormalities than using clinical medical officers. PMID:1747671

A programme on supplementary health education of medical staff from city polyclinics in the prevention and treatment of arterial hypertension was launched in one of the Moscow districts for 3 years. Another district was used as a comparison subject. Representative samples of residents aged 35-64 years from the two districts were screened before and after implementation of the programme. The WHO International MONICA programme was used to evaluate the efficiency of the programme proposed by the authors. The intervention district showed an improvement of hypertensives' awareness of the disease and a double increase in the number of patients with a high compliance. In the comparison district, these parameters remained unchanged. According to the criteria developed in the MONICA programme, there was a downward tendency in the incidence of myocardial infarction and stroke and these diseases-related deaths in the intervention district, whereas this was not observed in the district under comparison.

This study investigates the possibility of introducing depression and developmental screening tools into the National Programme on Immunization (NPI) in southeast Nigeria. The specific objectives were to determine the prevalence of postpartum depression (PPD) among mothers attending immunization clinics and to assess the association of maternal PPD and infant growth in relation to World Health Organization (WHO) recommendations. Four hundred and eight (408) mothers completed the sociodemographic questionnaire and the self-report Edinburgh Postnatal Depression Scale (EPDS). The weights, lengths and head circumferences of their infants were recorded, while the WHO recommended equivalents at 50th percentiles were also recorded for each child. The mothers were then interviewed with the major depressive episode module of Mini International Neuropsychiatric Interview (M.I.N.I.) to make diagnosis of depression. About 24.8% and 15.2% of the mothers were found to be depressed using EPDS and major depressive episode module of M.I.N.I., respectively. It was found that maternal PPD is significantly associated with the growth parameters of weights and lengths of the infants studied but not their head circumference. NPI may provide appropriate forum for early screening of mothers for PPD and interventions in Nigeria. The NPI would also serve a useful avenue of screening for developmental concerns in Nigerian children. © 2014.

This study identified whether children who had screened positive for either developmental language disorder (DLD) or autism spectrum disorder (ASD) at the age of 2.5 years had neurodevelopmental assessments five years later. Our study cohort were 288 children born from 1 July 2008 to 20 June 2009 who screened positive for DLD and, or, ASD at 2.5 years. Of these, 237 children were referred to, and assessed, at the Paediatric Speech and Language Pathology clinic (n = 176) or the Child Neuropsychiatry Clinic (n = 61) at the Queen Silvia Children's Hospital, Gothenburg, Sweden. Clinical registers covering all relevant outpatient clinics were reviewed five years later with regard to established diagnoses. When the 237 were followed up five years later, 96 (40%) had established neurodevelopmental disorders or problems, often beyond DLD and ASD. Co-existing problems were common in this cohort and multidisciplinary assessments were indicated. The other 60% did not appear in subsequent clinic records. It is likely that this 40% was a minimum rate and that more children will be referred for developmental problems later. Five years after they had been screened positive for DLD and, or autism at 2.5 years, 40% of our cohort had remaining or other developmental problems. ©2018 Foundation Acta Paediatrica.

Cervical cancer is a global leading cause of morbidity and mortality, attributable to the death of approximately 266,000 women every year. Majority (87%) of cervical cancer deaths occur in developing countries including Tanzania. Though knowledge of cervical cancer is an important determinant of women's participation in prevention and screening for cervical cancer, little is known about this topic in Tanzania. This study aimed to determine the knowledge of cervical cancer prevention services and screening practices among women who attended Reproductive Child Health clinic at a district hospital in Lake Zone, Tanzania. This information is important to help designing appropriate interventions and scaling up cervical cancer control programs, hence accelerate the achievement towards Sustainable Development Goals. A cross-sectional study was conducted from March to June 2017, involving 307 women attending reproductive and child health clinic at Magu district hospital. A questionnaire adopted from the validated Cervical Cancer Awareness Measure was used to collect data from the study participants. Data was analysed using SPSS version 20. Descriptive statistics were summarized using frequencies and percentages for categorical variables while mean and standard deviation was used for continuous variables. Multivariable logistic regressions model was used to estimate Adjusted Odds ratio with 95% CI for factors associated with knowledge. Knowledge of cervical cancer was low, where 82.7% of the women scored less than 50%. Majority (82.4%) were aware about cervical cancer. Secondary education or higher (OR = 7.77, 95% CI: 1.70-35.48) and "knowing someone who has ever had cervical cancer" (OR = 2.19, 95% CI: 1.16-4.13) were significantly associated with higher knowledge. Only 14.3% of participants practiced cervical cancer screening. Majority of women lack comprehensive knowledge of cervical cancer and only few utilize screening services. Strategies for awareness creation about cervical cancer may help to improve knowledge and utilization of cancer screening practices.

Knowledge and practices of general practitioners at district hospitals towards cervical cancer prevention in Burundi, 2015: a cross-sectional study.

Well-organized screening and treatment programmes are effective to prevent Invasive Cervical Cancer (ICC) in LMICs. To achieve this, the World Health Organization (WHO) recommends the involvement of existing health personnel in casu doctors, nurses, midwives in ICC prevention. A necessary precondition is that health personnel have appropriate knowledge about ICC. Therefore, to inform policy makers and training institutions in Burundi, we documented the knowledge and practices of general practitioners (GPs) at district hospital level towards ICC control. A descriptive cross-sectional survey was conducted from February to April, 2015 among all GPs working in government district hospitals. A structured questionnaire and a scoring system were used to assess knowledge and practices of GPs. The participation rate was 58.2%. Majority of GPs (76.3%) had appropriate knowledge (score > 70%) on cervical cancer disease; but some risk factors were less well known as smoking and the 2 most important oncogenic HPV. Only 8.4% of the participants had appropriate knowledge on ICC prevention: 55% of the participants were aware that HPV vaccination exists and 48.1% knew cryotherapy as a treatment method for CIN. Further, 15.3% was aware of VIA as a screening method. The majority of the participants (87%) never or rarely propose screening tests to their clients. Only 2 participants (1.5%) have already performed VIA/VILI. Wrong thoughts were also reported: 39.7% thought that CIN could be treated with radiotherapy; 3.1% thought that X-ray is a screening method. In this comprehensive assessment, we observed that Burundian GPs have a very low knowledge level about ICC prevention, screening and treatment. Suboptimal practices and wrong thoughts related to ICC screening and treatments have also been documented. We therefore recommend an adequate pre- and in-service training of GPs and most probably nurses on ICC control before setting up any public health intervention on ICC control.

Historically the western sahelian dry regions of Mali are known to be highly endemic for cutaneous leishmaniasis (CL) caused by Leishmania major, while cases are rarely reported from the Southern savanna forest of the country. Here, we report baseline prevalence of CL infection in 3 ecologically distinct districts of Mali (dry sahelian, north savanna and southern savanna forest areas). We screened 195 to 250 subjects from 50 to 60 randomly selected households in each of the 6 villages (four from the western sahelian district of Diema in Kayes region, one from the central district of Kolokani and one from the southern savanna district of Kolodieba, region of Sikasso). The screening consisted of: 1] A Leishmanin Skin Test (LST) for detection of exposure to Leishmania parasites; 2] clinical examination of suspected lesions, followed by validation with PCR and 3] finger prick blood sample to determine antibody levels to sand fly saliva. LST positivity was higher in the western district of Diema (49.9%) than in Kolokani (24.9%) and was much lower in Kolondieba (2.6%). LST positivity increased with age rising from 13.8% to 88% in Diema for age groups 2-5 years and 41-65 years, respectively. All eight PCR-confirmed L. major CL cases were diagnosed in subjects below 18 years of age and all were residents of the district of Diema. Exposure to sand fly bites, measured by anti-saliva antibody titers, was comparable in individuals living in all three districts. However, antibody titers were significantly higher in LST positive individuals (P<0.0001). In conclusion, CL transmission remains active in the western region of Mali where lesions were mainly prevalent among children under 18 years old. LST positivity correlated to higher levels of antibodies to sand fly salivary proteins, suggesting their potential as a risk marker for CL acquisition in Mali.

Inborn errors of metabolism (IEM) are genetic conditions that are sometimes associated with intellectual developmental disorders (IDD). The aim of this study is to contribute to the metabolic characterization of IDD of unknown etiology in Mexico. Metabolic screening using tandem mass spectrometry and fluorometry will be performed to rule out IEM. In addition, target metabolomic analysis will be done to characterize the metabolomic profile of patients with IDD. Identification of new metabolomic profiles associated with IDD of unknown etiology and comorbidities will contribute to the development of novel diagnostic and therapeutic schemes for the prevention and treatment of IDD in Mexico.

Parents' evaluation of developmental status: how well do parents' concerns identify children with behavioral and emotional problems?

PubMed

Glascoe, Frances Page

2003-03-01

This study was undertaken to determine which parental concerns are most associated with significant behavioral/emotional problems and the extent to which parents' concerns can be depended on in the detection of mental health problems. An additional goal is to view how well a recently published screening test relying on parents' concerns, Parents' Evaluation of Developmental Status (PEDS), detects behavioral and emotional problems. Subjects were a national sample of 472 parents and their children (21 months to 8 years old) who were participants in 1 of 2 test standardization and validation studies. Sites included various pediatric settings, public schools, and Head Start programs in 5 diverse geographic locations. Subjects were representative of U.S. demographics in terms of ethnicity, parental level of education, gender, and socioeconomic status. At each site, psychological examiners, educational diagnosticians, or school psychologists recruited families, and obtained informed consent. Examiners disseminated a demographics questionnaire (in English or Spanish) and a developmental screening test that relies on parents' concerns (PEDS). Examiners were blinded to PEDS' scoring and interpretation administered either by interview or in writing, the Eyberg Child Behavior Inventory (ECBI) or the Possible Problems Checklist (PPC), a subtest of the Child Development Inventory that includes items measuring emotional well-being and behavioral self-control. PEDS was used to sort children into risk for developmental disabilities according to various types of parental concern. Those identified as having high or moderate risk were nominated for diagnostic testing or screening followed by developmental and mental health services when indicated. Because their emotional and behavioral needs would have been identified and addressed, these groups were removed from the analysis (N = 177). Of the 295 children who would not have been nominated for further scrutiny on PEDS due to their low risk of developmental problems, 102 had parents with concerns not predictive of developmental disabilities (e.g., behavior, social skills, self-help skills) and 193 had no concerns at all. Of the 295 children, 12% had scores on either the ECBI or the PPC indicative of mental health problems. Two parental concerns were identified through logistic regression as predictive of mental health status: behavior (OR = 4.74, CI = 1.69-13.30); and social skills (OR = 5.76, CI = 2.46-13.50). If one or more of these concerns was present, children had 8.5 times the risk of mental health problems (CI = 3.69-19.71) In children 434 years of age and older, one or both concerns was 87% sensitive and 79% specific to mental health status, figures keeping with standards for screening test accuracy. In young children, the presence of one or both concerns was 68% sensitive and 66% specific to mental health status. The findings suggest that certain parental concerns, if carefully elicited, can be depended on to detect mental health problems when children are 41 years and older and at low risk of developmental problems. For younger children, clinicians should counsel parents in disciplinary techniques, follow up, and if suggestions were not effective, administer a behavioral-emotional screening test such as the Pediatric Symptoms Checklist or the ECBI before making a referral decision.

Effect of Fee on Cervical Cancer Screening Attendance--ScreenFee, a Swedish Population-Based Randomised Trial.

2016-01-01

Attendance in the cervical cancer screening programme is one of the most important factors to lower the risk of contracting the disease. Attendance rates are often low in areas with low socioeconomic status. Charging a fee for screening might possibly decrease attendance in this population. Screening programme coverage is low in low socio-economic status areas in Gothenburg, Sweden, but has increased slightly after multiple interventions in recent years. For many years, women in the region have paid a fee for screening. We studied the effect of abolishing this fee in a trial emanating from the regular cervical cancer screening programme. Individually randomised controlled trial. All 3 124 women in three low-resource areas in Gothenburg, due for screening during the study period, were randomised to receive an offer of a free test or the standard invitation stating the regular fee of 100 SEK (≈11 €). The study was conducted during the first six months of 2013. Attendance was defined as a registered Pap smear within 90 days from the date the invitation was sent out. Attendance did not differ significantly between women who were charged and those offered free screening (RR 0.93; CI 0.85-1.02). No differences were found within the districts or as an effect of age, attendance after the most recent previous invitation or previous experience of smear taking. Abolishment of a modest screening fee in socially disadvantaged urban districts with low coverage, after previous multiple systematic interventions, does not increase attendance in the short term. Other interventions might be more important for increasing attendance in low socio-economic status areas. ClinicalTrials.gov NCT02378324.

Toddler Developmental Delays After Extensive Hospitalization: Primary Care Practitioner Guidelines.

PubMed

Lehner, Dana C; Sadler, Lois S

2015-01-01

This review investigated developmental delays toddlers may encounter after a lengthy pediatric hospitalization (30 days or greater). Physical, motor, cognitive, and psychosocial development of children aged 1 to 3 years was reviewed to raise awareness of factors associated with developmental delay after extensive hospitalization. Findings from the literature suggest that neonatal and pediatric intensive care unit (NICU/PICU) graduates are most at risk for developmental delays, but even non-critical hospital stays interrupt development to some extent. Primary care practitioners (PCPs) may be able to minimize risk for delays through the use of formal developmental screening tests and parent report surveys. References and resources are described for developmental assessment to help clinicians recognize delays and to educate families about optimal toddler development interventions. Pediatric PCPs play a leading role in coordinating health and developmental services for the young child following an extensive hospital stay.

Moving beyond the mother-child dyad: women's education, child immunization, and the importance of context in rural India.

PubMed

Parashar, Sangeeta

2005-09-01

The argument that maternal education is critical for child health is commonplace in academic and policy discourse, although significant facets of the relationship remain empirically and theoretically challenged. While individual-level analyses consistently suggest that maternal education enhances child health outcomes, another body of literature argues that the observed causality at the individual-level may, in fact, be spurious. This study contributes to the debate by examining the contextual effects of women's education on children's immunization in rural districts of India. Multilevel analyses of data from the 1994 Human Development Profile Index and the 1991 district-level Indian Census demonstrate that a positive and significant relationship exists between the proportion of literate females in a district and a child's complete immunization status within that district, above and beyond the child's own mother's education as well as district-level socioeconomic development and healthcare amenities. However, results also indicate that the effect of maternal education cannot be downplayed. Thus, increasing women's literacy at the community level, in addition to mother's access to higher education-such as matriculation and beyond-at the individual-level, emerge as effective developmental tools.

Risks associated with communication delays in infants from underserved South African communities.

For optimal development young children need warm, responsive, enriched and communicative environments for learning social, language, and other skills. Infants and toddlers exposed to psychosocial risk lack enriched environments and may present with communication delays. To investigate the relationship between psychosocial risks and communication delays in infants from underserved communities in South Africa. Primary healthcare facilities in Tshwane district, South Africa. A parent interview and Rossetti Infant Toddler Language Scales were used to collect data from caregivers of 201 infants aged 6–12 months, selected through convenience sampling. Associations between communication delays and risks were determined (Chi-square and Fisher's exact tests). A log-linear model analysis was used to model the simultaneous effect of significant risks on the probability of having communication delays. Communication delays were present in 13% of infants. Infants with two or more siblings, born from mothers aged 18–29 years who own their house, had a 39% chance of presenting with communication delays. Developmental screening and early intervention is important in primary healthcare contexts in South Africa, as a clear relationship has been established between three risk factors and communication delays in infants.

To enable selection of novel chemicals for new processes, there is a recognized need for alternative toxicity screening assays to assess potential risks to man and the environment. For human health hazard assessment these screening assays need to be translational to humans, have high throughput capability, and from an animal welfare perspective be harmonized with the principles of the 3Rs (Reduction, Refinement, Replacement). In the area of toxicology a number of cell culture systems are available but while these have some predictive value, they are not ideally suited for the prediction of developmental and reproductive toxicology (DART). This is because they often lack biotransformation capacity, multicellular or multi- organ complexity, for example, the hypothalamus pituitary gonad (HPG) axis and the complete life cycle of whole organisms. To try to overcome some of these limitations in this study, we have used Caenorhabditis elegans (nematode) and Danio rerio embryos (zebrafish) as alternative assays for DART hazard assessment of some candidate chemicals being considered for a new commercial application. Nematodes exposed to Piperazine and one of the analogs tested showed a slight delay in development compared to untreated animals but only at high concentrations and with Piperazine as the most sensitive compound. Total brood size of the nematodes was also reduced primarily by Piperazine and one of the analogs. In zebrafish Piperazine and analogs showed developmental delays. Malformations and mortality in individual fish were also scored. Significant malformations were most sensitively identified with Piperazine, significant mortality was only observed in Piperazine and only at the higest dose. Thus, Piperazine seemed the most toxic compound for both nematodes and zebrafish. The results of the nematode and zebrafish studies were in alignment with data obtained from conventional mammalian toxicity studies indicating that these have potential as developmental toxicity screening systems. The results of these studies also provided reassurance that none of the Piperazines tested are likely to have any significant developmental and/or reproductive toxicity issues to humans when used in their commercial applications.

A voluntary screening of uterus cervix cancer took place in Kossodo health district from February 1st 2001 to April 30th 2002. It involved the age-group women of 25 to 59 years. This study included 239 women given a participation rate of 6.8%. We had sampled young women in three categories with average age of 38 years: a) doing a remunerated job (64.9%); b) mostly educated (85.3%); and c) married (86.2%). The visual inspection was the method used after the application of 4% acetic acid followed by that of lugol. In all 74 biopsies have been undertaken. Furthermore, we have noticed a 4.2% prevalence of pre-cancerous injuries. The cancerous lesions represented 2.5% of the sampling and the inflammatory lesions 13.4%. VPH infection was found on 2.5% samples and condylomatous injuries in 5% cases. This experience would deserve to be carried out always and a cervix cancer screening campaign held at national level.

To explore how growth measurements and attainment of developmental milestones in early childhood reflect the need for full-time special education (SE). After stratification in this population-based study, 900 pupils in full-time SE groups (age-range 7-16 years, mean 12 years 8 months) at three levels and 301 pupils in mainstream education (age-range 7-16, mean 12 years 9 months) provided data on height and weight from birth to age 7 years and head circumference to age 1 year. Developmental screening was evaluated from age 1 month to 48 months. Statistical methods included a general linear model (growth measurements), binary logistic regression analysis (odds ratios for growth), and multinomial logistic regression analysis (odds ratios for developmental milestones). At 1 year, a 1 standard deviation score (SDS) decrease in height raised the probability of SE placement by 40%, and a 1 SDS decrease in head size by 28%. In developmental screening, during the first months of life the gross motor milestones, especially head support, differentiated the children at levels 0-3. Thereafter, the fine motor milestones and those related to speech and social skills became more important. Children whose growth is mildly impaired, though in the normal range, and who fail to attain certain developmental milestones have an increased probability for SE and thus a need for special attention when toddlers age. Similar to the growth curves, these children seem to have consistent developmental curves (patterns).

To determine the prevalence of anaemia during pregnancy in Anuradhapura district and evaluate present screening methods for anaemia. Modified WHO 30 cluster sampling method with increased precision was used to estimate the prevalence of anaemia in the Anuradhapura district, Sri Lanka. Serum haemoglobin was measured using methemoglobin method. Clinical examination was carried out to evaluate the conjunctival method in anaemia screening. Values recorded from haemoglobin colour scale method used in the field antenatal clinics were collected. A total of 990 pregnant women participated in the study. In the first, second and third trimesters, prevalence of anaemia was 7.6%, 19.7% and 19.3% respectively. Gestational age adjusted anaemia prevalence among pregnant women in this study population was 14.1% (95% CI 12.0-16.4%). Mean and median haemoglobin concentration of the study sample was 11.8g/dL (SD 1.02g/dl and IQR 11.2-12.5g/dl). Among anaemic pregnant women, average values for Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), and Mean Corpuscular Haemoglobin Concentration (MCHC) were, 82.9 fl (SD 11.5), 27.6 (SD-3.6) pg/cell and 32.9g/dl (SD 1.8) respectively. Sensitivity and specificity of haemoglobin colour scale method was 50% (95% CI 29.0-71.0%) and 76.3% (95% CI 66.9-83.7%) respectively. Sensitivity and specificity of conjunctival method in detecting anaemia during pregnancy was 18.8% (95% CI 11.9-28.4) and 69.3% (95% CI 58.2- 78.6%). Prevalence of anaemia in the district of Anuradhapura was less than 50% of the estimated prevalence for Sri Lanka. Both haemoglobin colour scale and conjunctival method were having low validity in detecting anaemia in pregnancy.

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.

We here present a report of population screening programs (January 2012-December 2015) conducted by the Thalassemia Control Unit, Imambara Sadar Hospital, Chinsurah, Hooghly in the Hooghly District of West Bengal, India for prevention of thalassemia. We screened β-thalassemia (β-thal) heterozygotes and homozygotes, and Hb E (HBB: c.79G > A)-β-thal compound heterozygotes. Among 21 137 cases, we found 1968 heterozygotes and 192 homozygotes or compound heterozygotes. Results were evaluated with standard hematological analyses including red cell indices, hemoglobin (Hb) typing and quantification. The participants of the screening program were divided into six groups (children, pre-marriage cases, post-marital cases, family members of affected individuals, family members of carriers and pregnant women). While considering the average frequency of carriers, many reports recorded both related individuals (family members of trait and affected individuals) as well as unrelated individuals such as school children and pregnant women. These would have to be considered separately and only the unrelated individuals taken to estimate carrier frequencies in this article that would give more realistic data on carrier frequency of unrelated individuals.

Universal screening increases the representation of low-income and minority students in gifted education.

PubMed

Card, David; Giuliano, Laura

2016-11-29

Low-income and minority students are substantially underrepresented in gifted education programs. The disparities persist despite efforts by many states and school districts to broaden participation through changes in their eligibility criteria. One explanation for the persistent gap is that standard processes for identifying gifted students, which are based largely on the referrals of parents and teachers, tend to miss qualified students from underrepresented groups. We study this hypothesis using the experiences of a large urban school district following the introduction of a universal screening program for second graders. Without any changes in the standards for gifted eligibility, the screening program led to large increases in the fractions of economically disadvantaged and minority students placed in gifted programs. Comparisons of the newly identified gifted students with those who would have been placed in the absence of screening show that Blacks and Hispanics, free/reduced price lunch participants, English language learners, and girls were all systematically "underreferred" in the traditional parent/teacher referral system. Our findings suggest that parents and teachers often fail to recognize the potential of poor and minority students and those with limited English proficiency.

To evaluate the effects of a 26-week, high-intensity, parent-implemented Early Start Denver Model (P-ESDM) intervention on developmental outcomes, severity of autism spectrum disorder (ASD), and parental stress of ASD toddlers in China. Subjects in P-ESDM group (n = 23) were recruited from 1.5- to 2.5-year-old toddlers who were screened positive in Xuhui and Minhang Districts and were diagnosed with ASD. A community (comparison) group of age-matched toddlers with ASD (n = 20) was recruited from other areas. Subjects of the P-ESDM group attended 1.5-hr parent coaching per week for 26 weeks, and those in the community group received interventions available from communities. Assessments were conducted at baseline (T1) and 26 weeks later (T2). After adjusting for baseline differences between the two groups, P-ESDM group demonstrated greater improvement than the community group in general development, especially in Language domain. Neither group demonstrated significant change in ASD severity, but the P-ESDM group showed greater improvement in social affect, parent-reported social communication and symbolic play than community group did. Finally, parents in P-ESDM group experienced decreased parenting stress while those in community group showed an opposite trend, though the differences did not reach significant association with the P-ESDM intervention. Chinese toddlers with ASD receiving 26 weeks of P-ESDM via regular coaching sessions showed significant greater improvement than those receiving community interventions in multiple aspects of development including social communications. These findings add support to the importance of providing early screening, diagnosis, and immediate referral for evidence-based interventions to improve outcome of young children with ASD.

The development of early screening and diagnosis of autism spectrum disorder (ASD) in China has highlighted the importance of early intervention for young children with ASD. Our current study demonstrated that parent-implemented Early Start Denver Model (P-ESDM) via coaching from professionals improved developmental outcomes, especially in the language domain, and social communicational behaviors of Chinese toddlers with ASD. P-ESDM may help parents in China provide effective early intervention to their children with ASD via improving their skills when they are still at a waiting list for services or lack access to intervention, and has the potential to alleviate their parenting stress. © 2017 International Society for Autism Research, Wiley Periodicals, Inc.

Evaluation and Referral for Developmental Dysplasia of the Hip in Infants.

PubMed

Shaw, Brian A; Segal, Lee S

2016-12-01

Developmental dysplasia of the hip (DDH) encompasses a wide spectrum of clinical severity, from mild developmental abnormalities to frank dislocation. Clinical hip instability occurs in 1% to 2% of full-term infants, and up to 15% have hip instability or hip immaturity detectable by imaging studies. Hip dysplasia is the most common cause of hip arthritis in women younger than 40 years and accounts for 5% to 10% of all total hip replacements in the United States. Newborn and periodic screening have been practiced for decades, because DDH is clinically silent during the first year of life, can be treated more effectively if detected early, and can have severe consequences if left untreated. However, screening programs and techniques are not uniform, and there is little evidence-based literature to support current practice, leading to controversy. Recent literature shows that many mild forms of DDH resolve without treatment, and there is a lack of agreement on ultrasonographic diagnostic criteria for DDH as a disease versus developmental variations. The American Academy of Pediatrics has not published any policy statements on DDH since its 2000 clinical practice guideline and accompanying technical report. Developments since then include a controversial US Preventive Services Task Force "inconclusive" determination regarding usefulness of DDH screening, several prospective studies supporting observation over treatment of minor ultrasonographic hip variations, and a recent evidence-based clinical practice guideline from the American Academy of Orthopaedic Surgeons on the detection and management of DDH in infants 0 to 6 months of age. The purpose of this clinical report was to provide literature-based updated direction for the clinician in screening and referral for DDH, with the primary goal of preventing and/or detecting a dislocated hip by 6 to 12 months of age in an otherwise healthy child, understanding that no screening program has eliminated late development or presentation of a dislocated hip and that the diagnosis and treatment of milder forms of hip dysplasia remain controversial.

Cholangiocarcinoma (CCA), a major problem of health in Thailand, particularly in Northeastern and Northern regions, is generally incurable and rapidly lethal because of presentation in stage 3 or 4. Early diagnosis of stage 1 and 2 could allow better survival. Therefore, this study aimed to provide a distribution map of populations at risk for CCA in BuaYai district of Nakhon Ratchasima province, Northeast Thailand. A cross-sectional survey was carried out in 10 sub-districts and 122 villages, during June and November 2015. The populations at risk for CCA were screened using the Korat CCA verbal screening test (KCVST) and then risk areas were displayed by using Google map (GM). A total of 11,435 individuals from a 26,198 population completed the KCVST. The majority had a low score of risk for CCA (1-4 points; 93.3%). High scores with 6, 7 and 8 points accounted for 1.20%, 0.13% and 0.02%. The population at risk was found frequently in sub-district municipalities, followed by sub-district administrative organization and town municipalities, (F=396.220, P-value=0.000). Distribution mapping comprised 11 layers: 1, district; 2, local administrative organization; 3, hospital; 4, KCVST opisthorchiasis; 5, KCVST praziquantel used; 6, KCVST cholelithiasis; 7, KCVST raw fish consumption; 8, KCVST alcohol consumption; 9, KCVST pesticide used; 10, KCVST relative family with CCA; and 11, KCVST naive northeastern people. Geovisual display is now available online. This study indicated that the population at high risk of CCA in Bua Yai district is low, therefore setting a zero model project is possible. Key success factors for disease prevention and control need further study. GM production is suitable for further CCA surveillance and monitoring of the population with a high risk score in this area.

SUMMARY Phenotypic variation is a prerequisite for evolution by natural selection, yet the processes that give rise to the novel morphologies upon which selection acts are poorly understood. We employed a chemical genetic screen to identify developmental changes capable of generating ecologically relevant morphological variation as observed among extant species. Specifically, we assayed for exogenously applied small molecules capable of transforming the ancestral larval foregut of the herbivorous Xenopus laevis to resemble the derived larval foregut of the carnivorous Lepidobatrachus laevis. Appropriately, the small molecules that demonstrate this capacity modulate conserved morphogenetic pathways involved in gut development, including downregulation of retinoic acid (RA) signaling. Identical manipulation of RA signaling in a species that is more closely related to Lepidobatrachus, Ceratophrys cranwelli, yielded even more similar transformations, corroborating the relevance of RA signaling variation in interspecific morphological change. Finally, we were able to recover the ancestral gut phenotype in Lepidobatrachus by performing a reverse chemical manipulation to upregulate RA signaling, providing strong evidence that modifications to this specific pathway promoted the emergence of a lineage-specific phenotypic novelty. Interestingly, our screen also revealed pathways that have not yet been implicated in early gut morphogenesis, such as thyroid hormone signaling. In general, the chemical genetic screen may be a valuable tool for identifying developmental mechanisms that underlie ecologically and evolutionarily relevant phenotypic variation. PMID:23607305

This review article aims to introduce the screening and referral network of genetic evaluation for children with developmental delay in Taiwan. For these children, integrated systems provide services from the medical, educational, and social welfare sectors. All cities and counties in Taiwan have established a network for screening, detection, referral, evaluation, and intervention services. Increased awareness improves early detection and intervention. There remains a gap between supply and demand, especially with regard to financial resources and professional manpower. Genetic etiology has a major role in prenatal causes of developmental delay. A summary of reports on some related genetic disorders in the Taiwanese population is included in this review. Genetic diagnosis allows counseling with regard to recurrence risk and prevention. Networking with neonatal screening, laboratory diagnosis, genetic counseling, and orphan drugs logistics systems can provide effective treatment for patients. In Taiwan, several laboratories provide genetic tests for clinical diagnosis. Accessibility to advanced expensive tests such as gene chips or whole exome sequencing is limited because of funding problems; however, the service system in Taiwan can still operate in a relatively cost-effective manner. This experience in Taiwan may serve as a reference for other countries. Copyright © 2014. Published by Elsevier B.V.

Developmental screening tools: feasibility of use at primary healthcare level in low- and middle-income settings.

Fischer, Vinicius Jobim; Morris, Jodi; Martines, José

2014-06-01

An estimated 150 million children have a disability. Early identification of developmental disabilities is a high priority for the World Health Organization to allow action to reduce impairments through Gap Action Program on mental health. The study identified the feasibility of using the developmental screening and monitoring tools for children aged 0-3 year(s) by non-specialist primary healthcare providers in low-resource settings. A systematic review of the literature was conducted to identify the tools, assess their psychometric properties, and feasibility of use in low- and middle-income countries (LMICs). Key indicators to examine feasibility in LMICs were derived from a consultation with 23 international experts. We identified 426 studies from which 14 tools used in LMICs were extracted for further examination. Three tools reported adequate psychometric properties and met most of the feasibility criteria. Three tools appear promising for use in identifying and monitoring young children with disabilities at primary healthcare level in LMICs. Further research and development are needed to optimize these tools.

Organ-specific in vitro toxicity assays are often highly sensitive, but they lack specificity. We evaluated here examples of assay features that can affect test specificity, and some general procedures are suggested on how positive hits in complex biological assays may be defined. Differentiating human LUHMES cells were used as potential model for developmental neurotoxicity testing. Forty candidate toxicants were screened, and several hits were obtained and confirmed. Although the cells had a definitive neuronal phenotype, the use of a general cell death endpoint in these cultures did not allow specific identification of neurotoxicants. As alternative approach, neurite growth was measured as an organ-specific functional endpoint. We found that neurite extension of developing LUHMES was specifically inhibited by diverse compounds such as colchicine, vincristine, narciclasine, rotenone, cycloheximide, or diquat. These compounds reduced neurite growth at concentrations that did not compromise cell viability, and neurite growth was affected more potently than the integrity of developed neurites of mature neurons. A ratio of the EC50 values of neurite growth inhibition and cell death of >4 provided a robust classifier for compounds associated with a developmental neurotoxic hazard. Screening of unspecific toxicants in the test system always yielded ratios <4. The assay identified also compounds that accelerated neurite growth, such as the rho kinase pathway modifiers blebbistatin or thiazovivin. The negative effects of colchicine or rotenone were completely inhibited by a rho kinase inhibitor. In summary, we suggest that assays using functional endpoints (neurite growth) can specifically identify and characterize (developmental) neurotoxicants.

Screen time and young children: Promoting health and development in a digital world.

2017-11-01

The digital landscape is evolving more quickly than research on the effects of screen media on the development, learning and family life of young children. This statement examines the potential benefits and risks of screen media in children younger than 5 years, focusing on developmental, psychosocial and physical health. Evidence-based guidance to optimize and support children's early media experiences involves four principles: minimizing, mitigating, mindfully using and modelling healthy use of screens. Knowing how young children learn and develop informs best practice strategies for health care providers.

Koraput, a predominantly tribe-inhabited and one of the highly endemic districts of Odisha State that contributes a substantial number of malaria cases to the India's total. Control of malaria in such districts would contribute to change the national scenario on malaria situation. Hence, a study was carried out to measure the magnitude of malaria prevalence in the district to strengthen the malaria control activities. Prevalence of malaria was assessed through a sample blood survey (SBS) in seven randomly selected community health centres (CHCs). Individuals of all age groups in the villages selected (one in each subcentre) were screened for malaria infection. Both thick and thin smears were prepared from blood samples collected by finger prick, stained and examined for malaria parasites searching 100 fields in each smear. The results of a blood survey (n = 10,733) carried out, as a part of another study, during 1986-87 covering a population of 17,722 spread in 37 villages of Koraput district were compared with the current survey results. Software SPSS version 16.0 was used for data analysis. During the current study, blood survey was done in 135 villages screening 12,045 individuals (16.1% of the total population) and among them, 1,983 (16.5%) were found positive for malaria parasites. Plasmodium falciparum was the major malaria parasite species accounted for 89.1% (1,767) of the total positives; Plasmodium vivax and Plasmodium malariae accounted for 9.3% (184) and 0.2% (5), respectively. Gametocytes were found in 7.7% (n = 152) of the positive cases. The majority of parasite carriers (78.9%) were afebrile. The 1986-87 blood survey showed that of 10,733 people screened, 833 (7.8%) were positive for malaria parasites, 714 (85.7%) with P. falciparum, 86 (10.3%) with P. vivax, 12 (1.4%) with P. malariae and 21 (2.5%) with mixed infections. The results of the current study indicated a rising trend in transmission of malaria in Koraput district compared to the situation during 1986-87 and indicated the necessity for a focused and reinforced approach for the control of the disease by improving people's access to diagnosis and treatment and ensuring implementation of the intervention measures with adequate coverage and compliance.

Impact of expanded newborn screening--United States, 2006.

PubMed

2008-09-19

Universal newborn screening for selected metabolic, endocrine, hematologic, and functional disorders is a well-established practice of state public health programs. Recent developments in tandem mass spectrometry (MS/MS), which is now capable of multi-analyte analysis in a high throughput capacity, has enabled newborn screening to include many more disorders detectable from a newborn blood spot. In 2006, to address the substantial variation that existed from state to state in the number of disorders included in newborn screening panels, the American College of Medical Genetics (ACMG), under guidance from the Health Resources and Services Administration, recommended a uniform panel of 29 disorders, which was subsequently endorsed by the federal Advisory Committee on Heritable Disorders in Newborns and Children. After 2006, most states began to expand their panels to include all 29 disorders; currently, 21 states and the District of Columbia have fully implemented the ACMG panel. To estimate the burden to state newborn screening programs resulting from this expansion, CDC used 2001-2006 data from those states with well-established MS/MS screening programs to estimate the number of children in the United States who would have been identified with disorders in 2006 if all 50 states and the District of Columbia had been using the ACMG panel. This report describes the results of that analysis, which indicated that, although such an expansion would have increased the number of children identified by only 32% (from 4,370 to 6,439), these children would have had many rare disorders that require local or regional capacity to deliver expertise in screening, diagnosis, and management. The findings underscore the need for public health and health-care delivery systems to build or expand the programs required to manage the rare disorders detected through expanded newborn screening, while also continuing programs to address more common disorders.

To eliminate blinding trachoma, the World Health Organization emphasizes implementing the SAFE strategy, which includes annual mass drug administration (MDA) with azithromycin to the whole population of endemic districts. Prevalence surveys to assess impact at the district level are recommended after at least 3 years of intervention. The decision to stop MDA is based on a prevalence of trachomatous inflammation follicular (TF) among children aged 1-9 years below 5% at the sub-district level, as determined by an additional round of surveys limited within districts where TF prevalence is below 10%. We conducted impact surveys powered to estimate prevalence simultaneously at the sub-district and district in two zones of Amhara, Ethiopia to determine whether MDA could be stopped. Seventy-two separate population-based, sub-district surveys were conducted in 25 districts. In each survey all residents from 10 randomly selected clusters were screened for clinical signs of trachoma. Data were weighted according to selection probabilities and adjusted for correlation due to clustering. Overall, 89,735 residents were registered from 21,327 households of whom 72,452 people (80.7%) were examined. The prevalence of TF in children aged 1-9 years was below 5% in six sub-districts and two districts. Sub-district level prevalence of TF in children aged 1-9 years ranged from 0.9-76.9% and district-level from 0.9-67.0%. In only one district was the prevalence of trichiasis below 0.1%. The experience from these zones in Ethiopia demonstrates that impact assessments designed to give a prevalence estimate of TF at sub-district level are possible, although the scale of the work was challenging. Given the assessed district-level prevalence of TF, sub-district-level surveys would have been warranted in only five districts. Interpretation was not as simple as stopping MDA in sub-districts below 5% given programmatic challenges of exempting sub-districts from a highly regarded program and the proximity of hyper-endemic sub-districts.

In 2005 through 2009, the Centers for Disease Control and Prevention (CDC) funded 5 sites to implement a colorectal cancer screening program for uninsured, low-income populations. These 5 sites composed a demonstration project intended to explore the feasibility of establishing a national colorectal cancer screening program through various service delivery models. A longitudinal, multiple case study was conducted to understand and document program implementation processes. Using metaphor as a qualitative analytic technique, evaluators identified stages of maturation across the programmatic life cycle. Analysis rendered a working theory of program development during screening implementation. In early stages, program staff built relationships with CDC and local partners around screening readiness, faced real-world challenges putting program policies into practice, revised initial program designs, and developed new professional skills. Midterm implementation was defined by establishing program cohesiveness and expanding programmatic reach. In later stages of implementation, staff focused on sustainability and formal program closeout, which prompted reflection about personal and programmatic accomplishments. Demonstration sites evolved through common developmental stages during screening implementation. Findings elucidate ways to target technical assistance to more efficiently move programs along their maturation trajectory. In practical terms, the time and cost associated with guiding a program to maturity may be potentially shortened to maximize return on investment for both organizations and clients receiving service benefits. © 2013 American Cancer Society.

A study of dental manpower distribution was made in Shanghai Pudong new district in order to analyze the needs and demands for dental services in Shanghai Pudong new district, to forecast the developmental trends of dental demand in the future and to provide basis for regional programs of dental manpower in the urban areas of China. An analysis was made in 601 subjects taken from all age groups in Shanghai Pudong new district by stratified and cluster random sampling and in 83 medical institutions of stomatology in Shanghai Pudong new district by mass examination. The amount of dental manpower need and demand was computed and forecasted by means of health care need and demand and proportional analogy methods. The total amounts needed were 755-834 dentists. The total amounts demanded were 285-314 dentists. It was forecasted that the figures would be 392-1041 in the year of 2010. The prevalence of oral disease was 90.18%, but only 37.66% of subjects visited dentist in a year. The ratio of dentists to the population was 1:9375. The unbalance between demand for and supply of dental manpower was mainly due to negative awareness of people, the irrationalness of demand levels, problems from service provider and the irrationalness of dental manpower levels.

The Ten Questions tool was developed in 1984 as a low-cost, simple screen for childhood disability and referral for diagnosis in low-resource settings, and its use in Nepal has not been previously evaluated. Preterm birth and intrauterine growth restriction are potential risk factors for child disability and loss of developmental potential, but there are few studies examining this relationship from developing settings.   To examine the associations of small for gestational age and preterm birth as predictors of Ten Questions Plus positivity. The Ten Questions Plus questionnaire was administered to caregivers of 680 children between 2 and 5 years of age from August 2007 to March 2008 in rural Sarlahi, southern Nepal. Participants had previously been enrolled in a randomized trial of chlorhexidine cleansing at birth. At 1 month of age, children were then enrolled into a randomized 2 × 2 factorial trial of daily iron and zinc supplementation between October 2001 and January 2006. None. Positive screen on the Ten Questions Plus tool defined as a positive response to one or more questions. Of preterm children, 37 (33.6%) had a positive response to at least one question on the Ten Questions Plus and were considered at risk for disability. One hundred and seventy term children (29.8%) were at risk for disability. The Ten Questions Plus tool can be used in this rural Nepali setting to identify children at increased risk for mental and physical disability to be targeted for further examination. The prevalence of parent-reported disabilities is high in this population (almost one-third of children); children who are both preterm and small-for-gestational age are at increased risk for motor milestone delay, reported learning difficulty, speech and behavioural problems. Intrauterine growth restriction may affect child development and result in disabilities later in childhood. © 2011 Blackwell Publishing Ltd.

Choueiri, Roula; Wagner, Sheldon

2015-08-01

To develop a clinically valid interactive level 2 screening assessment for autism spectrum disorders (ASD) in toddlers that is brief, easily administered, and scored by clinicians. We describe the development, training, standardization, and validation of the Rapid Interactive Screening Test for Autism in Toddlers (RITA-T) with ASD-specific diagnostic instruments. The RITA-T can be administered and scored in 10 minutes. We studied the validity of the RITA-T to distinguish between toddlers with ASD from toddlers with developmental delay (DD)/non-ASD in an early childhood clinic. We also evaluated the test's performance in toddlers with no developmental concerns. We identified a cutoff score based on sensitivity, specificity, and positive predictive value of the RITA-T that best differentiates between ASD and DD/non-ASD. A total of 61 toddlers were enrolled. RITA-T scores were correlated with ASD-specific diagnostic tools (r = 0.79; P < .01) and ASD clinical diagnoses (r = 0.77; P < .01). Mean scores were significantly different in subjects with ASD, those with DD/non-ASD, and those with no developmental concerns (20.8 vs 13 vs 10.6, respectively; P < .0001). At a cutoff score of >14 , the RITA-T had a sensitivity of 1.00, specificity of 0.84, and positive predictive value of 0.88 for identifying ASD risk in a high-risk group. The RITA-T is a promising new level 2 interactive screening tool for improving the early identification of ASD in toddlers in general pediatric and early intervention settings and allowing access to treatment.

Our objective is to study the seroprevalence of toxoplasmosis in the voluntary blood donors of Puducherry and surrounding districts of Tamil Nadu. A total of 275 healthy blood donors were screened for the presence of IgM and IgG antibodies to Toxoplasma gondii by ELISA test. Donor samples positive for IgM and/or IgG antibodies to T. gondii were subjected to IgG avidity ELISA. While, 54 out of 275 donors had IgG antibodies (19.66%), only one donor had IgM (0.36%) along with IgG. Among 54 IgG positive donors, only two had low avidity (3.7%), indicating recent exposure to the protozoa. Feasibility and cost effectiveness studies should be conducted throughout India to decide regarding screening of blood donors for toxoplasmosis.

The study was undertaken in South Andaman district, comprising three tehsils, viz. Port Blair, Ferrargunj and Little Andaman Tehsils, respectively. Intensive pupal infestation surveys were carried out along the National Highway (NH 223), the main passenger and trade route, referred to as Great Andaman Trunk Road. Sampling locations at every 3 km were geo-referenced with global positioning system unit. A total of 17314 water collections were examined from 29 locations across the South Andaman district, among which 1021 (5.9%) were colonized by immature stages of Aedes albopictus, Aedes aegypti and other mosquito species. Ae. aegypti were found in 12 locations, showing higher infestation in the densely built Aberdeen Bazaar. Breeding populations of Ae. albopictus were observed in 27 sampling locations. Both the species were not recorded in two Northern localities. In the areas where both the species are present, they were often found in the same developmental sites, suggesting convergent habitat selection. The most frequently encountered man-made, artificial and natural developmental sites were fixed cement tanks, plastic drums, plastic cans, metal drums, metal pots, discarded tires, coconut shells, leaf axils and tree holes. Ae. aegypti and Ae. albopictus were observed in varying proportions in Port Blair and Ferrargunj Tehsils, while the former species appeared to be absent in Little Andaman. This study elucidates the spatial distribution of Ae. aegypti and Ae. albopictus with preponderance of the latter species, pointing towards arboviral transmission and assumes public health importance in South Andaman district, endemic for dengue.

2007-09-01

Genome-wide array comparative genomic hybridization screening is uncovering pathogenic submicroscopic chromosomal imbalances in patients with developmental disorders. In those patients, imbalances appear now to be scattered across the whole genome, and most patients carry different chromosomal anomalies. Screening patients with developmental disorders can be considered a forward functional genome screen. The imbalances pinpoint the location of genes that are involved in human development. Because most imbalances encompass regions harboring multiple genes, the challenge is to (1) identify those genes responsible for the specific phenotype and (2) disentangle the role of the different genes located in an imbalanced region. In this review, we discuss novel tools and relevant databases that have recently been developed to aid this gene discovery process. Identification of the functional relevance of genes will not only deepen our understanding of human development but will, in addition, aid in the data interpretation and improve genetic counseling.

Phenotypic screening for developmental neurotoxicity ...

EPA Pesticide Factsheets

There are large numbers of environmental chemicals with little or no available information on their toxicity, including developmental neurotoxicity. Because of the resource-intensive nature of traditional animal tests, high-throughput (HTP) methods that can rapidly evaluate chemicals for the potential to affect the developing brain are being explored. Typically, HTP screening uses biochemical and molecular assays to detect the interaction of a chemical with a known target or molecular initiating event (e.g., the mechanism of action). For developmental neurotoxicity, however, the mechanism(s) is often unknown. Thus, we have developed assays for detecting chemical effects on the key events of neurodevelopment at the cellular level (e.g., proliferation, differentiation, neurite growth, synaptogenesis, network formation). Cell-based assays provide a test system at a level of biological complexity that encompasses many potential neurotoxic mechanisms. For example, phenotypic assessment of neurite outgrowth at the cellular level can detect chemicals that target kinases, ion channels, or esterases at the molecular level. The results from cell-based assays can be placed in a conceptual framework using an Adverse Outcome Pathway (AOP) which links molecular, cellular, and organ level effects with apical measures of developmental neurotoxicity. Testing a wide range of concentrations allows for the distinction between selective effects on neurodevelopmental and non-specific

[The Battelle developmental inventory screening test for early detection of developmental disorders in cerebral palsy].

PubMed

Moraleda-Barreno, E; Romero-López, M; Cayetano-Menéndez, M J

2011-12-01

Cerebral palsy is usually associated with motor, cognitive, and language deficits, and with other disorders that cause disability in daily living skills, personal independence, social interaction and academic activities. Early detection of these deficits in the clinical setting is essential to anticipate and provide the child with the necessary support for adapting to the environment in all possible areas. The main objective of this study is to demonstrate that these deficits can be detected at an early age and comprehensively through the use of a brief development scale. We studied 100 children between 4 and 70 months old, half of them with cerebral palsy and the other half without any disorder. All subjects were evaluated using the Battelle Developmental Inventory screening test. We compared the developmental quotients in both groups and between the subjects with different motor impairments, using a simple prospective ex post facto design. The test detected statistically significant differences between the clinical group and the control group at all age levels. Statistically significant differences were also found between tetraplegia and other motor disorders. There were no differences by gender. The deficit in development associated with cerebral palsy can be quantified at early ages through the use of a brief development scale, thus we propose that the systematic implementation of protocols with this screening tool would be helpful for treatment and early intervention. This would also help in anticipating and establishing the means for the multidisciplinary actions required, and could provide guidance to other health professionals, to provide adequate school, social, and family support,.

This paper focuses on the National Action Alliance for Suicide Prevention's Research Prioritization Task Force's Aspirational Goal 2 (screening for suicide risk) as it pertains specifically to children, adolescents, and young adults. Two assumptions are forwarded: (1) strategies for screening youth for suicide risk need to be tailored developmentally; and (2) we must use instruments that were created and tested specifically for suicide risk detection and developed specifically for youth. Recommendations for shifting the current paradigm include universal suicide screening for youth in medical settings with validated instruments. Published by Elsevier Inc.

Developmental dyslexia is a lifelong impairment affecting 5% to 10% of the population. In French-speaking countries, although a number of standardized tests for dyslexia in children are available, tools suitable to screen for dyslexia in adults are lacking. In this study, we administered the "Alouette" reading test to a normative sample…

Phenotypic variation is a prerequisite for evolution by natural selection, yet the processes that give rise to the novel morphologies upon which selection acts are poorly understood. We employed a chemical genetic screen to identify developmental changes capable of generating ecologically relevant morphological variation as observed among extant species. Specifically, we assayed for exogenously applied small molecules capable of transforming the ancestral larval foregut of the herbivorous Xenopus laevis to resemble the derived larval foregut of the carnivorous Lepidobatrachus laevis. Appropriately, the small molecules that demonstrate this capacity modulate conserved morphogenetic pathways involved in gut development, including downregulation of retinoic acid (RA) signaling. Identical manipulation of RA signaling in a species that is more closely related to Lepidobatrachus, Ceratophrys cranwelli, yielded even more similar transformations, corroborating the relevance of RA signaling variation in interspecific morphological change. Finally, we were able to recover the ancestral gut phenotype in Lepidobatrachus by performing a reverse chemical manipulation to upregulate RA signaling, providing strong evidence that modifications to this specific pathway promoted the emergence of a lineage-specific phenotypic novelty. Interestingly, our screen also revealed pathways that have not yet been implicated in early gut morphogenesis, such as thyroid hormone signaling. In general, the chemical genetic screen may be a valuable tool for identifying developmental mechanisms that underlie ecologically and evolutionarily relevant phenotypic variation. © 2013 Wiley Periodicals, Inc.

Effects of medicinal compounds on the differentiation of the eukaryotic microorganism dictyostelium discoideum: can this model be used as a screening test for reproductive toxicity in humans?

Dictyostelium discoideum is a single-cell, eukaryotic microorganism that can undergo multicellular development in order to produce dormant spores. We investigated the capacity of D. discoideum to be used as a rapid screening system for potential developmental toxicity of compounds under development as pharmaceuticals. We used a set of four transgenic D. discoideum strains that expressed a reporter gene under the control of promoters that are active at certain time periods and in distinct cell types during D. discoideum development. We found that teratogens such as valproic acid, tretinoin, or thalidomide interfered to various extents with D. discoideum development, and had different effects on prestalk and prespore cell-specific reporter gene expression. Phenytoin was inactive in this assay, which may point to limitations in metabolization of the compound in Dictyostelium required to exert developmental toxicity. D. discoideum cell culture is cheap and easy to handle compared to mammalian cell cultures or animal teratogenicity models. Although the Dictyostelium-based assay described in this report may not securely predict the teratogenic potential of these drugs in humans, this organism may be qualified for rapid large-scale screenings of synthetic compounds under development as new pharmaceuticals for their potential to interfere with developmental processes and thus help to reduce the amount of teratogenicity tests in animal models.

New findings on object permanence: A developmental difference between two types of occlusion

PubMed Central

Moore, M. Keith; Meltzoff, Andrew N.

2013-01-01

Manual search for totally occluded objects was investigated in 10-, 12- and 14-month-old infants. Infants responded to two types of total hiding in different ways, supporting the inference that object permanence is not a once-and-for-all attainment. Occlusion of an object by movement of a screen over it was solved at an earlier age than occlusion in which an object was carried under the screen. This dissociation was not explained by motivation, motor skill or means–ends coordination, because for both tasks the same object was hidden in the same place under the same screen and required the same uncovering response. This dissociation generalized across an experimentally manipulated change in recovery means—infants removed cloths while seated at a table in Expt 1 and were required to crawl through 3-D space to displace semi-rigid pillows in Expt 2. Further analysis revealed that emotional response varied as a function of hiding, suggesting an affective correlate of infant cognition. There are four empirical findings to account for: developmental change, task dissociation, generalization of the effects across recovery means, and emotional reactions. An identity-development theory is proposed explaining these findings in terms of infants’ understanding of object identity and the developmental relationship between object identity and object permanence. Object identity is seen as a necessary precursor to the development of object permanence. PMID:25364086

Ecological conditions and developmental senescence significantly affect the physiological metabolism of plants, yet relatively little is known about the influence of geographical location on dynamic changes in plant leaves during growth. Pseudotargeted gas chromatography-selected ion monitoring-mass spectrometry and capillary electrophoresis-mass spectrometry were used to investigate a time course of the metabolic responses of tobacco leaves to geographical location. Principal component analysis revealed obvious metabolic discrimination between growing districts relative to cultivars. A complex carbon and nitrogen metabolic network was modulated by environmental factors during growth. When the Xuchang and Dali Districts in China were compared, the results indicated that higher rates of photosynthesis, photorespiration and respiration were utilized in Xuchang District to generate the energy and carbon skeletons needed for the biosynthesis of nitrogen-containing metabolites. The increased abundance of defense-associated metabolites generated from the shikimate-phenylpropanoid pathway in Xuchang relative to Dali was implicated in protection against stress. PMID:26549189

Since 2006, the Peruvian National TB program (NTP) recommends voluntary counseling and testing (VCT) for all tuberculosis (TB) patients. Responding to the differential burden of both diseases in Peru, TB is managed in peripheral health facilities while HIV is managed in referral centers. This study aims to determine the coverage of HIV screening among TB patients and the characteristics of persons not screened. From March 2010 to December 2011 we enrolled new smear-positive pulmonary TB adults in 34 health facilities in a district in Lima. NTP staff offered VCT to all TB patients. Patients with an HIV positive result were referred for confirmation tests and management. We interviewed patients to collect their demographic and clinical characteristics and registered if patients opted in or out of the screening. Of the 1295 enrolled TB patients, nine had a known HIV diagnosis. Of the remaining, 76.1% (979) were screened for HIV. Among the 23.9% (307) not screened, 38.4% (118) opted out of the screening. TB patients at one of the health care facilities of the higher areas of the district (OR = 3.38, CI 95% 2.17-5.28 for the highest area and OR = 2.82, CI 95% 1.78-4.49 for the high area) as well as those reporting illegal drug consumption (OR = 1.65, CI 95% 1.15-2.37) were more likely not to be screened. Twenty-four were HIV positive (1.9% of all patients 1295, or 2.4% of those screened). Of 15 patients diagnosed with HIV during the TB episode, ten were enrolled in an HIV program. The median time between the result of the HIV screening and the first consultation at the HIV program was 82 days (IQR, 32-414). The median time between the result of the HIV screening and antiretroviral initiation was 148.5 days (IQR 32-500). An acceptable proportion of TB patients were screened for HIV in Lima. Referral systems of HIV positive patients should be strengthened for timely ART initiation.

Because retinoblastoma typically arises at a very young age, children are particularly vulnerable to vision impairment, associated developmental delays, and functional limitations. Limited information is available describing developmental delay and functional limitations in this population, necessitating supportive services including rehabilitation. The aims of this study were to describe the participation of children with newly diagnosed retinoblastoma in an occupational therapy program that identifies children in need of rehabilitation services. We also identify indications for referral to rehabilitation services among children with newly diagnosed retinoblastoma and enumerate the likelihood of these children receiving the recommended services. Twenty-two children participated in longitudinal occupational therapy assessments during the first year after diagnosis. We recommended 1 or more types of rehabilitation services for 16 of 22 (72.7%) participants. Twelve of 16 (75%) received services. The results of this pilot study indicate that implementing a prospective occupational therapy-screening program is feasible and results in identification and initiation of therapy services in some children with retinoblastoma. Developmental screenings and follow-up of children with retinoblastoma is strongly recommended.

Pre-school children with suspected autism spectrum disorders: do girls and boys have the same profiles?

Andersson, Gunilla Westman; Gillberg, Christopher; Miniscalco, Carmela

2013-01-01

The male to female ratio is raised in autism spectrum disorders (ASD). Previous studies have suggested that girls with ASD have more problems with communication than boys, but boys show more repetitive behaviours than girls. In this study, 20 girls, 1.8-3.9 years of age were matched for chronological and developmental age with 20 boys with suspected ASD. All the children were recruited after population screening and referral by Child Health Care Services to a specialised neuropsychiatry clinic, where they underwent comprehensive neuropsychiatric assessments. Comparisons were made with regard to diagnosis, developmental profiles and global disability. No significant gender differences were found. There were strong correlations between results obtained in different developmental areas. The results suggest that either (1) previous studies finding clear gender differences may have overrated discrepancies between girls and boys in ASD, or that (2) there may be girls, who will not be identified in the early years with our current screening instruments. More research with a much larger population representative study samples is required. Copyright © 2012 Elsevier Ltd. All rights reserved.

Objective We assessed the prevalence of autism spectrum disorders (ASD) and screening test characteristics in children with Down syndrome. Method Eligible children born in a defined geographic area between January 1, 1996, and December 31, 2003, were recruited through a population-based birth defects registry and community outreach, then screened with the modified checklist for autism in toddlers or social communication questionnaire, as appropriate. Screen-positive children and a random sample of screen-negative children underwent developmental evaluation. Results We screened 123 children (27.8% of the birth cohort). Mean age was 73.4 months (range, 31–142). Compared to screen-negative children, screen-positive children had similar sociodemo-graphic characteristics but a lower mean developmental quotient (mean difference: 11.0; 95% confidence interval: 4.8–17.3). Weighted prevalences of autistic disorder and total ASD were 6.4% (95% confidence interval [CI]: 2.6%–11.6%) and 18.2% (95% CI: 9.7%–26.8%), respectively. The estimated minimum ASD prevalence, accounting for unscreened children, is 5.1% (95% CI: 3.3%–7.4%). ASD prevalence increased with greater cognitive impairment. Screening test sensitivity was 87.5% (95% CI: 66.6%–97.7%); specificity was 49.9% (95% CI: 37.0%–61.4%). Conclusion The prevalence of ASD among children with Down syndrome aged 2 to 11 years is substantially higher than in the general population. The modified checklist for autism in toddlers and social communication questionnaire were highly sensitive in children with Down syndrome but could result in many false positive tests if universal screening were implemented using current algorithms. Research needs include development of specific ASD screening algorithms and improved diagnostic discrimination in children with Down syndrome. Timely identification of these co-occurring diagnoses is essential so appropriate interventions can be provided. PMID:20375732

Cereal crops can suffer substantial damage if frosts occur at heading. Identification of post-head-emergence frost (PHEF) resistance in cereals poses a number of unique and difficult challenges. Many decades of research have failed to identify genotypes with PHEF resistance that could offer economically significant benefit to growers. Research and breeding gains have been limited by the available screening systems. Using traditional frost screening systems, genotypes that escape frost injury in trials due to spatial temperature differences and/or small differences in phenology can be misidentified as resistant. We believe that by improving techniques to minimize frost escapes, such 'false-positive' results can be confidently identified and eliminated. Artificial freezing chambers or manipulated natural frost treatments offer many potential advantages but are not yet at the stage where they can be reliably used for frost screening in breeding programmes. Here we describe the development of a novel photoperiod gradient method (PGM) that facilitates screening of genotypes of different phenology under natural field frosts at matched developmental stages. By identifying frost escapes and increasing the efficiency of field screening, the PGM ensures that research effort can be focused on finding genotypes with improved PHEF resistance. To maximize the likelihood of identifying PHEF resistance, we propose that the PGM form part of an integrated strategy to (i) source germplasm;(ii) facilitate high throughput screening; and (iii) permit detailed validation. PGM may also be useful in other studies where either a range of developmental stages and/or synchronized development are desired.

Sensitivity and Specificity of 2 Autism Screeners Among Referred Children Between 16 and 48 Months of Age.

Autism screening is recommended by the American Academy of Pediatrics and the Centers for Disease Control and Prevention at ages 18 and 24 months. Popular screening tests have been validated for the age range of 16 to 30 months. However, only a minority of children with autism spectrum disorder (ASD) are identified by age 3 years, and many are not identified until after they enter school. Thus, we aimed to measure the sensitivity and specificity of 2 available screening tests for ASDs in children older than 30 months. We assessed the sensitivity and specificity of 2 ASD screening tools administered to parents of children who were referred to a developmental clinic between the ages of 16 and 48 months: the Modified Checklist for Autism in Toddlers (M-CHAT) and the Parent's Observations of Social Interactions (POSI), which is a component of a comprehensive screening instrument called, the Survey of Well-being of Young Children. Both the M-CHAT and the POSI had acceptable sensitivity (≥75%) among children across the age range studied. Their specificity was limited by the fact that the study was conducted in a developmental referral clinic. Two readily available screening tools, the POSI and the M-CHAT, have acceptable sensitivity in evaluating risk for autism in children at least to age 48 months. Further research should investigate their sensitivity and specificity when used in primary care settings.

Refractive error is one of the major causes of blindness and visual impairment in children; but community based studies are scarce especially in rural parts of Ethiopia. So, this study aims to assess the prevalence of refractive error and its magnitude as a cause of visual impairment among school-age children of rural community. This community-based cross-sectional descriptive study was conducted from March 1 to April 30, 2009 in rural villages of Goro district of Gurage Zone, found south west of Addis Ababa, the capital of Ethiopia. A multistage cluster sampling method was used with simple random selection of representative villages in the district. Chi-Square and t-tests were used in the data analysis. A total of 570 school-age children (age 7-15) were evaluated, 54% boys and 46% girls. The prevalence of refractive error was 3.5% (myopia 2.6% and hyperopia 0.9%). Refractive error was the major cause of visual impairment accounting for 54% of all causes in the study group. No child was found wearing corrective spectacles during the study period. Refractive error was the commonest cause of visual impairment in children of the district, but no measures were taken to reduce the burden in the community. So, large scale community level screening for refractive error should be conducted and integrated with regular school eye screening programs. Effective strategies need to be devised to provide low cost corrective spectacles in the rural community.

Purpose/Objectives To explore perceptions of colorectal cancer (CRC) and self-reported CRC screening behaviors among ethnic subgroups of U.S. blacks. Design Descriptive, cross-sectional, exploratory, developmental pilot. Setting Medically underserved areas in Hillsborough County, FL. Sample 62 men and women aged 50 years or older. Ethnic subgroup distribution included 22 African American, 20 English-speaking Caribbean-born, and 20 Haitian-born respondents. Methods Community-based participatory research methods were used to conduct face-to-face individual interviews in the community. Main Research Variables Ethnic subgroup, health access, perceptions of CRC (e.g., awareness of screening tests, perceived risk, perceived barriers to screening), healthcare provider recommendation, and self-reported CRC screening. Findings Awareness of CRC screening tests, risk perception, healthcare provider recommendation, and self-reported use of screening were low across all subgroups. However, only 55% of Haitian-born participants had heard about the fecal occult blood test compared to 84% for English-speaking Caribbean-born participants and 91% for African Americans. Similarly, only 15% of Haitian-born respondents had had a colonoscopy compared to 50% for the English-speaking Caribbean and African American subgroups. Conclusions This exploratory, developmental pilot study identified lack of awareness, low risk perception, and distinct barriers to screening. The findings support the need for a larger community-based study to elucidate and address disparities among subgroups. Implications for Nursing Nurses play a major role in reducing cancer health disparities through research, education, and quality care. Recognition of the cultural diversity of the U.S. black population can help nurses address health disparities and contribute to the health of the community. PMID:20797950

This descriptive cross-sectional study identified resources and programs that are available nationwide on the Internet to support individuals and families with intellectual and developmental disabilities (I/DD), with a focus on intellectual disability. This evaluation included easily identifiable information on specific resources and highlighted unique programs found in individual states that were linked from e-government websites. Researchers documented the ease of access and available information for all 50 states and the District of Columbia. A number of disparities and areas for improvement were recorded for states and I/DD websites. The researchers conclude that a number of additional health and support services will be needed to address the growing needs of this vulnerable population.

There is a lack of high quality evidence available to guide clinical practice in the treatment and management of developmental dysplasia of the hip (DDH). Evidence has been limited by persistent confusion on diagnostic and classification terminology, variability in surgeon decision making and a reliance on single centre, retrospective studies with small patient numbers. To address gaps in knowledge regarding screening, diagnosis and management of DDH, the International Hip Dysplasia Institute began a multicentre, international prospective study on infants with hips dislocated at rest. This review discusses the current state of screening, diagnostic and management practices in DDH and addresses important unanswered questions that will be critical in identifying best practices and optimising patient outcomes. There is insufficient evidence to support universal ultrasound screening; instead, selective screening should be performed by 6-8 weeks of age on infants with risk factors of breech presentation, family history, or history of clinical hip instability. Follow-up of infants with risk factors and normal initial screening should be considered to at least 6 months of age. Brace treatment is a sensible first-line treatment for management of dislocated hips at rest in infants < 6 months of age. Early operative reduction may be considered as there is insufficient evidence to support a protective role for the ossific nucleus in the development of avascular necrosis.

RNAi screening of developmental toolkit genes: a search for novel wing genes in the red flour beetle, Tribolium castaneum.

PubMed

Linz, David M; Tomoyasu, Yoshinori

2015-01-01

The amazing array of diversity among insect wings offers a powerful opportunity to study the mechanisms guiding morphological evolution. Studies in Drosophila (the fruit fly) have identified dozens of genes important for wing development. These genes are often called candidate genes, serving as an ideal starting point to study wing development in other insects. However, we also need to explore beyond the candidate genes to gain a more comprehensive view of insect wing evolution. As a first step away from the traditional candidate genes, we utilized Tribolium (the red flour beetle) as a model and assessed the potential involvement of a group of developmental toolkit genes (embryonic patterning genes) in beetle wing development. We hypothesized that the highly pleiotropic nature of these developmental genes would increase the likelihood of finding novel wing genes in Tribolium. Through the RNA interference screening, we found that Tc-cactus has a less characterized (but potentially evolutionarily conserved) role in wing development. We also found that the odd-skipped family genes are essential for the formation of the thoracic pleural plates, including the recently discovered wing serial homologs in Tribolium. In addition, we obtained several novel insights into the function of these developmental genes, such as the involvement of mille-pattes and Tc-odd-paired in metamorphosis. Despite these findings, no gene we examined was found to have novel wing-related roles unique in Tribolium. These results suggest a relatively conserved nature of developmental toolkit genes and highlight the limited degree to which these genes are co-opted during insect wing evolution.

We present the methodology of a population-based Randomised Controlled Trial, comparing an intensive programme of primary preschool vision screening by orthoptists with the usual non-specialist screening. The aims of the trial are to compare the effectiveness and costs of intensive orthoptic screening with non-specialist measures. The orthoptic screening programme will be evaluated both as a composite package and in terms of the screening value of the individual tests at specific ages. This trial is nested within a large population-based longitudinal study. Additional demographic and developmental data on the children in the trial are therefore available. The results of the trial will be used to help clarify which methods of preschool ophthalmic population screening are best in terms of disease detection and cost efficiency.

Introduction Atrial fibrillation (AF), the world’s most common arrhythmia, often goes undetected and untreated in low-resource communities, including India, where AF epidemiology is undefined. AF is an important risk factor for stroke, which plagues an estimated 1.6 million Indians annually. As such, early detection of AF and management of high-risk patients is critically important to decrease stroke burden in individuals with AF. This study aims to describe the epidemiology of AF in Anand District, Gujarat, India, characterise the clinical profile of individuals who are diagnosed with AF and determine the performance of two mobile technologies for community-based AF screening. Methods This observational study builds on findings from a previous feasibility study and leverages two novel technologies as well as an existing community health programme to perform door-to-door AF screening for 2000 people from 60 villages of Anand District, Gujarat, India using local health workers. A single-lead ECG and a pulse-based application is used to screen each individual for AF three times over a period of 5 days. Participants with suspected arrhythmias are followed up by study cardiologist who makes final diagnoses. Participants diagnosed with AF are initiated on treatment based on current anticoagulation guidelines and clinical reasoning.

This article describes the implementation of the Developmental Pathways Screening Program (DPSP) and an evaluation of program feasibility, acceptability, and yield. Using the Mood and Feelings Questionnaire (MFQ) and externalizing questions from the Youth Self Report (YSR; Achenbach, 2001), universal classroom-based emotional health screening was implemented with students as they began middle school. Of all sixth graders enrolled in four participating Seattle schools, 861 (83%) were screened. Students who screened positive for emotional distress (15% of students screened) received onsite structured clinical evaluations with children's mental health professionals. Seventy-one percent of students who were evaluated were found to be experiencing significant emotional distress, with 59% warranting referral to academic tutoring, school counselor, and/or community mental health services. Successful implementation of in-class screening was facilitated by strong collaboration between DPSP and school staff. Limitations of emotional health screening and the DPSP are discussed, and future steps are outlined. PMID:21430789

Objective Screening for psychosocial and behavioral risks, such as depression, intimate partner violence and smoking, during pregnancy is considered state-of-the-art in prenatal care. This prospective longitudinal analysis examines the added benefit of repeated screening over a one-time screen in identifying such risks during pregnancy. Design Data were collected as part of a randomized controlled trial to address intimate partner violence, depression, smoking and environmental tobacco smoke exposure in African-Americans women. Setting PNC sites in the District of Columbia serving mainly minority women Population 1044 African-American pregnant women in the District of Columbia Methods Mothers were classified by their initial response (acknowledgement of risks) and updated during pregnancy. Risks were considered new if they were not previously reported. Standard hypothesis tests and logistic regression were used to predict acknowledgment of any new risk(s) during pregnancy. Main Outcome Measures New risks; psychosocial variables to understand what factors might help identify acknowledgement of additional risk(s). Results Repeated screening identified more mothers acknowledging risk over time. Reported smoking increased by 11%, environmental tobacco smoke exposure by 19%, intimate partner violence by 9%, and depression by 20%. The psychosocial variables collected at the baseline that were entered into the logistic regression model included relationship status, education, Medicaid, illicit drug use, and alcohol use during pregnancy. Among these, only education less than high school was associated in acknowledgement of new risk in the bivariate analyses and significantly predicted identification of new risks (OR=1.39, 95%CI, 1.01-1.90). Conclusions It is difficult early on to predict who will acknowledge new risks over the course of pregnancy, thus all women should be screened repeatedly to allow identification and intervention during prenatal care.

This study examines whether parental report of social-communicative and repetitive behaviors at 12 months can be helpful in identifying autism spectrum disorder (ASD) in younger siblings of children with ASD [high-risk (HR)-siblings]. Parents of HR-siblings and infants without a family history of ASD completed the First Year Inventory at 12 months. Developmental outcomes were based on 24- or 36-month assessments. HR-siblings later diagnosed with ASD showed greater impairments in social communication than those with other developmental outcomes based on parental and clinician ratings. Parental report of decline in play and communication and impaired vocal imitation correctly classified a majority of ASD cases with high specificity. These preliminary findings have important implications for the development of early screening instruments for ASD in HR-siblings. PMID:25149178

Accurate and efficient developmental screening measures are critical for early identification of developmental problems; however, few reliable and valid tests are available in Korea as well as other countries outside the USA. The Ages and Stages Questionnaires (ASQ) was chosen for study with young children in Korea. The ASQ was translated into Korean and necessary cross-cultural adaptations were made. The translated version was then distributed and completed by 3220 parents of young children between the ages of 4 months and 5 years. Reliability was studied including domain correlations, internal consistency, and performance of identification cut-off scores for the Korean population. Rasch analyses including tests of Differential Item Functioning, contrasting Korean and US samples were also performed. In general, internal consistency of the Korean ASQ was high, with overall correlations 0.75 for communication, 0.85 for gross motor, 0.74 for fine motor, 0.72 for problem solving, and 0.65 for personal-social. Validity, including concurrent validity, also had strong evidence. Mean scores of children on the Korean translation of the ASQ and the US normative sample were generally similar. Rasch analyses indicated the majority of items functioned similarly across the Korean sample. In general, the ASQ was translated with cultural appropriateness in mind and functioned as a valid and reliable parent-completed screening test to assist in early identification of young children with developmental delays. Further research is needed to confirm these results with a larger and more diverse Korean sample.

There is no evidence on the effect of universal ultrasound screening on developmental dysplasia of the hip. We examined the impact of adding an ultrasound examination to a one examiner clinical screening strategy on treatment, follow-up rates and the number of cases detected late in a low-prevalence population. All eligible babies born at Kongsberg Hospital, Norway, from 1998 to 2006 (n = 4245) underwent both clinical and ultrasound hip examinations within three days of life. Indications for immediate treatment were positive Barlow or Ortolani manoeuvres and, or, sonographic dysplasia. Sonographic immature hips were followed until normalisation. Treatment rates and rates from the 1989 to 1997 prestudy period (n = 3594), including late diagnoses, were collected from hospital records. Treatment was initiated in 90 (2.1%) infants (74 girls), 63 (70%) from birth, compared to 33 (0.9%) during the prestudy period. The follow-up rate did not change (11%). There were two (0.5/1000) and four (1.0/1000) cases detected late, respectively. No one underwent surgery during the first year of life and no avascular necrosis was seen. Adding universal ultrasound to clinical screening performed by the same, experienced paediatrician doubled the treatment rate, without influencing the already low numbers of late cases. ©2017 Foundation Acta Paediatrica.

To describe the last 5 years' experience of Child Development Centre (CDC), Kerala Developmental Evaluation Clinic II for children between 2 and 10 y, referred for suspicion of developmental lag in the preschool years and scholastic difficulty in the primary classes with specific focus on developmental profile and the experience of the home based intervention package taught to the mothers. A team of evaluators including developmental therapist, preschool teacher with special training in clinical child development, speech therapist, special educator, clinical psychologist and developmental pediatrician assessed all the children referred to CDC Kerala. Denver Developmental Screening Test (DDST-II), Vineland Social Maturity Scale (VSMS) and Intelligent Quotient (IQ) tests were administered to all children below 6 y and those above 6 with apparent developmental delay. Speech/delay (35.9%), behavior problem (15.4%), global delay/ intellectual disability (15.4%), learning problem (10.9%), pervasive developmental disorders (7.7%), seizure disorder (1.7%), hearing impairment (0.7%), and visual impairment (0.7%) were the clinical diagnosis by a developmental pediatrician. Each child with developmental problem was offered a home based intervention package consisting of developmental therapy and special education items, appropriate to the clinical diagnosis of the individual child and the same was taught to the mother. The experience of conducting the developmental evaluation clinic for children between 2 and 10 y has shown that a team consisting of developmental therapist, speech therapist, preschool teacher, special educator, clinical child psychologist and developmental pediatrician, using appropriate test results of the child could make a clinical diagnosis good enough for providing early intervention therapy using a home based intervention package.

To study prevalence and risk factors for neurological disorders--epilepsy, global developmental delay, and motor, vision, and hearing defects--in children aged 6 months to 2 years in northern India. A two-stage community survey for neurological disorders was conducted in rural and urban areas of Lucknow. After initial screening with a new instrument, the Lucknow Neurodevelopment Screen, screen positives and a random proportion of screen negatives were validated using predefined criteria. Prevalence was calculated by weighted estimates. Demographic, socio-economic, and medical risk factors were compared between validated children who were positive and negative for neurological disorders by univariate and logistic regression analysis. Of 4801 children screened (mean age [SD] 15.32mo [5.96]; 2542 males, 2259 females), 196 were positive; 190 screen positives and 269 screen negatives were validated. Prevalence of neurological disorders was 27.92 per 1000 (weighted 95% confidence interval 12.24-43.60). Significant risk factors (p≤0.01) for neurological disorders were higher age in months (p=0.010), lower mean number of appliances in the household (p=0.001), consanguineous marriage of parents (p=0.010), family history of neurological disorder (p=0.001), and infants born exceptionally small (parental description; p=0.009). On logistic regression, the final model included age (p=0.0193), number of appliances (p=0.0161), delayed cry at birth (p=0.0270), postneonatal meningoencephalitis (p=0.0549), and consanguinity (p=0.0801). Perinatal factors, lower socio-economic status, and consanguinity emerged as predictors of neurological disorders. These factors are largely modifiable. © The Authors.

Telehealth Measures Screening for Developmental Language Disorders in Spanish-Speaking Toddlers

PubMed Central

2016-01-01

Abstract Background: This is the second of two studies that described the use of telehealth language screening measures for use with young Spanish-speaking children. Introduction: The purpose of this study was to describe the classification accuracy of individual telehealth language screening measures as well as the accuracy of combinations of measures used with Spanish-speaking toddler-age children from rural and underserved areas of the country. Materials and Methods: This study applied an asynchronous hybrid telehealth approach that implemented parent-structured play activities with a standard set of stimuli, and interaction with a My First Words e-book. These interactions were recorded with a mini camcorder. In addition, a traditional pen and paper parent questionnaire measure was collected. Sixty-two mostly Spanish-speaking preschool-age children and their parents participated. Twenty-two children had developmental language disorders (DLDs) and 40 had typical language development. Results: Although several of the individual measures were significantly and strongly associated with standardized language scores, only reported vocabulary had classification accuracy values that were desirable for screening for DLDs. An improvement was observed when reported vocabulary was combined with a number of different words children produced during interactions with parents. Conclusions: This research provides additional evidence showing the effectiveness of a hybrid telehealth model in screening the language development of Spanish-speaking children. More specifically, reported vocabulary combined with number of different words produced by a child can provide informative and accurate diagnostic information when screening Spanish-speaking toddler-age children for DLDs. These findings replicate the first study in showing that hybrid telehealth approaches that combine the use of video technology and traditional pen and paper surveys yield strong results, and may be a viable screening alternative when face-to-face access to a bilingual provider is not possible.

Wilson, D; Ratekin, C

1990-03-01

This article is intended to familiarize the ambulatory care provider with possible uses of children's drawings as assessment tools. Drawings can be a useful adjunct in detecting perceptual-motor difficulties and developmental delay, and can provide clues to self-image and family dynamics. Piaget's theory of cognitive development provides a framework to evaluate the child's intellectual development as reflected in drawings. The developmental scales of Koppitz are presented as a practical screening tool. The Koppitz scales include both developmental norms and items that might indicate emotional problems. Observing the child's drawing of the family provides clues to family dynamics. Becoming highly skilled in the evaluation of children's drawings requires a familiarity with neurophysiology, education, psychology, and psychoanalytic and developmental theory, along with intuition and practice. This article presents an introduction to evaluating children's drawings.

The mangrove killifish, Kryptolebias marmoratus, is unique among vertebrates due to its self-fertilizing mode of reproduction involving an ovotestis. As a result, it constitutes a simplistic and desirable vertebrate model for developmental genetics as it is easily maintained, reaches sexual maturity in about 100 days, and provides a manageable number of relatively clear embryos. After the establishment and characterization of an initial mutagenesis pilot screen using N-ethyl-N-nitrosourea, a three-generation genetic screen was performed to confirm zygotic mutant allele heritability and simultaneously score for homozygous recessive mutant sterile F2 fish. From a total of 307 F2 fish screened, 10 were found to be 1° males, 16 were sterile, 92 wild-type, and the remaining 189, carriers of zygotic recessive alleles. These carriers produced 25% progeny exhibiting several zygotic phenotypes similar to those previously described in zebrafish and in the aforementioned pilot screen, as expected. Interestingly, new phenotypes such as golden yolk, no trunk, and short tail were observed. The siblings of sterile F2 mutants were used to produce an F3 generation in order to confirm familial sterility. Out of the 284 F3 fish belonging to 10 previously identified sterile families, 12 were found to be 1° males, 69 were wild-type, 83 sterile, and 120 were classified as */+ (either wild-type or carriers) with undefined genotypes. This screen provides proof of principle that K. marmoratus is a powerful vertebrate model for developmental genetics and can be used to identify mutations affecting fertility. PMID:26801648

PURPOSE/BACKGROUND/INTRODUCTION: The aim of this study was to retrospectively evaluate the impact of neonatal sonographic hip screening using Graf's method for the management and outcome of orthopaedic treatment of decentered hip joints with developmental dysplasia of the hip (DDH), using three decades (1978-2007) of clinical information compiled in a medical database. Three representative cohorts of consecutive cases of decentered hip joints were selected according to different search criteria and inclusion and exclusion parameters: (1) cohort 1 (1978-1982; n = 80), without sonographic screening; (2) cohort 2.1 (1994-1996; n = 91), with nationwide established general sonographic screening according to the Graf-method; (3) cohort 2.2 (2003-2005; n = 91), with sonographic screening including referred cases for open reduction from non-screened populations. These three cohorts were compared for the following parameters: age at initial treatment, successful closed reduction, necessary overhead traction, necessary adductor-tenotomy, rate of open reduction, rate of avascular necrosis (AVN) and rate of secondary acetabuloplasty. The age at initial treatment was reduced from 5.5 months in the first cohort to 2 months in the two subsequent two cohorts and the rate of successful closed reduction increased from 88.7 to 98.9 and 95.6%, respectively. There was a statistically significant improvement in six out of seven parameters with sonographic hip screening; only the rate of secondary acetabuloplasty did not improve significantly. Compared to the era before the institution of a sonographic hip screening programme according to the Graf-method in Austria in 1992, ultrasound screening based-treatment of decentered hip joints has become safer, shorter and simpler: "safer" means lower rate of AVN, "shorter" means less treatment time due to earlier onset and "simpler" means that the devices are now less invasive and highly standardized.

Human pluripotent stem cells: an emerging model in developmental biology.

Zhu, Zengrong; Huangfu, Danwei

2013-02-01

Developmental biology has long benefited from studies of classic model organisms. Recently, human pluripotent stem cells (hPSCs), including human embryonic stem cells and human induced pluripotent stem cells, have emerged as a new model system that offers unique advantages for developmental studies. Here, we discuss how studies of hPSCs can complement classic approaches using model organisms, and how hPSCs can be used to recapitulate aspects of human embryonic development 'in a dish'. We also summarize some of the recently developed genetic tools that greatly facilitate the interrogation of gene function during hPSC differentiation. With the development of high-throughput screening technologies, hPSCs have the potential to revolutionize gene discovery in mammalian development.

SYNOPSIS: The question of how tissues and organs are shaped during development is crucial for understanding human birth defects. Data from high-throughput screening assays on human stem cells may be utilized predict developmental toxicity with reasonable accuracy. Other types of models are necessary, however, for mechanism-specific analysis because embryogenesis requires precise timing and control. Agent-based modeling and simulation (ABMS) is an approach to virtually reconstruct these dynamics, cell-by-cell and interaction-by-interaction. Using ABMS, HTS lesions from ToxCast can be integrated with patterning systems heuristically to propagate key events This presentation to FDA-CFSAN will update progress on the applications of in silico modeling tools and approaches for assessing developmental toxicity.

Use of Developmental Milestones in Pediatric Residency Training and Practice: Time to Rethink the Meaning of the Mean

Sices, Laura

2009-01-01

Objective Pediatricians frequently report the use of developmental milestones in monitoring young children’s development, despite evidence that use of screening tools improves detection of developmental delays. Methods Core texts in the field of pediatrics and developmental-behavioral pediatrics were reviewed for content and presentation on child development. Most texts included and many focused on developmental milestones, many with an emphasis on 50th percentile milestone data. Problems and limitations in the use of 50th percentile milestones to monitor young children’s development and to identify children whose development is suspicious for delay, include questionable utility in clinical decision making and the potential to increase parental anxiety. Results The recommendation is made to reconsider a focus on 50th percentile milestone data in pediatric training and practice, in favor of measures that have better clinical utility and are more psychometrically sound. Conclusion A conceptual approach to the presentation of developmental milestones differentiates the use of the 10th, 50th, and 90th percentiles of age of achievement of skills, based on the clinical purpose of surveillance.

Global developmental delay in guanidionacetate methyltransferase deficiency: differences in formal testing and clinical observation.

Guanidinoacetate N-methyltransferase (GAMT) deficiency is a defect in the biosynthesis of creatine (Cr). So far, reports have not focused on the description of developmental abilities in this disorder. Here, we present the result of formal testing of developmental abilities in a GAMT-deficient patient. Our patient, a 3-year-old boy with GAMT deficiency, presented clinically with a severe language production delay and nearly normal nonverbal development. Treatment with oral Cr supplementation led to partial restoration of the cerebral Cr concentration and a clinically remarkable acceleration of language production development. In contrast to clinical observation, formal testing showed a rather harmonic developmental delay before therapy and a general improvement, but no specific acceleration of language development after therapy. From our case, we conclude that in GAMT deficiency language delay is not always more prominent than delays in other developmental areas. The discrepancy between the clinical impression and formal testing underscores the importance of applying standardized tests in children with developmental delays. Screening for Cr deficiency by metabolite analysis of body fluids or proton magnetic resonance spectroscopy of the brain deficiency should be considered in any child with global developmental delay/mental retardation lacking clues for an alternative etiology.

This study, conducted in 2012 in two districts of the Congo (Bétou and Enyellé), screened for yaws (endemic treponemiasis) that could be treated by a single dose of azithromycin. The screening involved a clinical history, followed by a clinical examination of the children reporting dermatological problems. A rapid diagnostic test for treponema was performed on the children with suspicious lesions. Of 6215 children screened, 485 (7.8%) had such lesions; 480 (99.0%) of them had a rapid diagnostic test, and it was positive for 183 (38.1%). This so-called Morges strategy is aimed at eradicating yaws in endemic areas.

2016-01-01

To evaluate a child development surveillance tool proposal to be used in primary care, with simultaneous use of the Denver II scale. This was a cross-sectional study of 282 infants aged up to 36 months, enrolled in a public daycare in a countryside community in Rio Grande do Sul/Brazil. Child development was assessed using the surveillance tool and the Denver II scale. The prevalence of probable developmental delay was 53%; most of these cases were in the alert group and 24% had normal development, but with risk factors. At the Denver scale, the prevalence of suspected developmental delay was 32%. When risk factors and sociodemographic variables were assessed, no significant difference was observed. The evaluation of this surveillance tool resulted in objective and comparable data, which were adequate for a screening test. It is easily applicable as a screening tool, even though it was originally designed as a surveillance tool. The inclusion of risk factors to the scoring system is an innovation that allows for the identification of children with suspected delay in addition to developmental milestones, although the definition of parameters and choice of indicators should be thoroughly studied.

Evaluation of the Affymetrix CytoScan® Dx Assay for Developmental Delay

PubMed Central

Webb, Bryn D.; Scharf, Rebecca J.; Spear, Emily A.; Edelmann, Lisa J.; Stroustrup, Annemarie

2015-01-01

The goal of molecular cytogenetic testing for children presenting with developmental delay is to identify or exclude genetic abnormalities that are associated with cognitive, behavioral, and/or motor symptoms. Until 2010, chromosome analysis was the standard first-line genetic screening test for evaluation of patients with developmental delay when a specific syndrome was not suspected. In 2010, The American College of Medical Genetics and several other groups recommended chromosomal microarray (CMA) as the first-line test in children with developmental delays, multiple congenital anomalies, and/or autism. This test is able to detect regions of genomic imbalances at a much finer resolution than G-banded karyotyping. Until recently, no CMA testing had been approved by the United States Food and Drug Administration (FDA). This review will focus on the use of the Affymetrix CytoScan® Dx Assay, the first CMA to receive FDA approval for the genetic evaluation of individuals with developmental delay. PMID:25350348

The role of UK district nurses in providing care for adult patients with a terminal diagnosis: a meta-ethnography.

Offen, John

2015-03-01

To explore the role of UK district nurses in providing care for adult patients with a terminal diagnosis by reviewing qualitative research. Meta-ethnography was used to conduct the synthesis. CINAHL, MEDLINE and British Nursing Index (BNI) were searched comprehensively for primary research relating to the role of UK district nurses in palliative care. The abstracts and titles of 700 papers were screened against inclusion criteria, of these 97 full papers were appraised. Some 24 studies reported in 25 papers were selected for inclusion in the synthesis. In total, five key themes were identified: valuing the role; practical role; relationships with patients and families; providing psychological support; and role uncertainty. Further synthesis yielded two 'lines of argument'. The concept of the 'expert friend' argues that the atypical relationship district nurses cultivate with patients underpins district nurses' provision of palliative care and profoundly influences the nature of psychological support given. Secondly, the concept of 'threat and opportunity' encapsulates the threat district nurses can feel to their traditional role in palliative care through changing health and social policy, while recognising the benefits that access to specialist knowledge and better training can bring. The findings have implications for understanding the motivators and barriers experienced by district nurses delivering palliative care in a time of unprecedented change to community health services.

To investigate the visual abilities of students with severe developmental delay (DD) age 6-8 starting in special needs education. Between 1 January 2000 and 31 December 2008, we screened all students with severe DD starting in special needs schools in Northern Jutland, Denmark for vision. All students with visual acuities ≤6/12 were refractioned and examined by an ophthalmologist. Of 502 students, 56 (11%) had visual impairment (VI) [visual acuity (VA) ≤ 6/18], of which 21 had been previously undiagnosed. Legal blindness was found in 15 students (3%), of whom three had previously been undiagnosed. Students tested with preferential looking systems (N = 78) had significantly lower visual acuities [VA (decimal) = 0.55] than students tested with ortho types [VA (decimal) = 0.91] and had problems participating in the colour and form tests, possibly due to cerebral VI. The number of students with decreased vision identified by screening decreased significantly during the study period (r = 0.724, p = 0.028). The number of students needed to be screened to find one student with VI was 24 and to identify legal blindness 181 needed to be screened. Visual impairment is a common condition in students with severe DD. Despite increased awareness of VI in the school and health care system, we continued to find a considerable number of students with hitherto undiagnosed decreased vision. © 2011 The Authors.

In 2000, the first chemical screen using living zebrafish in a multi-well plate was reported. Since then, more than 60 additional screens have been published describing whole-organism drug and pathway discovery projects in zebrafish. To investigate the scope of the work reported in the last 14 years and to identify trends in the field, we analyzed the discovery strategies of 64 primary research articles from the literature. We found that zebrafish screens have expanded beyond the use of developmental phenotypes to include behavioral, cardiac, metabolic, proliferative and regenerative endpoints. Additionally, many creative strategies have been used to uncover the mechanisms of action of new small molecules including chemical phenocopy, genetic phenocopy, mutant rescue, and spatial localization strategies.

2012-06-01

Prior research has shown ultrasound (US) screening for developmental dysplasia of the hip (DDH) in preventive child health care to be more effective than the current screening method. In the present study, 3-month-old infants were screened for DDH with US. The objective of this study was to examine parental satisfaction with the screening and determinants that affect satisfaction. Parental satisfaction was measured using a questionnaire. Independent variables included socio-demographic determinants, structure, process and outcome-related determinants and the meeting of expectations. Satisfaction with the screening was high. Parents who perceived the screener as competent, had enough time to ask questions, perceived the proceeding as fluent, perceived a low burden on their infant and whose expectations were met, were more likely to be satisfied. Satisfaction was influenced by process-related factors and not by factors related to the structure and the outcome of the screening. Good information provision before the screening and communication during the screening are means by which parental satisfaction can be influenced positively.

High rates of tuberculosis (TB) and TB/HIV co-infection is often linked with mental health issues such as post-traumatic stress disorder (PTSD) symptoms, which is further associated with poor health outcomes. In a country such as South Africa where rates of these infectious diseases are high, it is concerning that there is limited/no data on prevalence rates of mental disorders such as PTSD and its associated factors. Therefore, the aim of this study was to establish the prevalence of PTSD symptoms and associated factors in TB, TB retreatment and/or TB-HIV co-infected primary public health-care patients in three districts in South Africa. Brief screening self-report tools were used to measure: PTSD symptoms, psychological distress (anxiety and depression) and alcohol misuse. Other relevant measures, such as adherence to medication, stressful life events and sexual risk-taking behaviours, were obtained through structured questions. A total of 4900 public primary care adult patients from clinics in high TB burden districts from three provinces in South Africa participated. All the patients screened positive for TB (either new or retreatment cases). The prevalence of PTSD symptoms was 29.6%. Patients who screened positive for PTSD symptoms and psychological distress were more likely to be on antidepressant medication. Factors that predicted PTSD symptoms were poverty, residing in an urban area, psychological distress, suicide attempt, alcohol and/or drug use before sex, unprotected sex, TB-HIV co-infected and the number of other chronic conditions. Health-care systems should be strengthened to improve delivery of mental health care, by focusing on existing programmes and activities, such as those which address the prevention and treatment of TB and HIV.

Screening for colorectal cancer with FOBT, virtual colonoscopy and optical colonoscopy: study protocol for a randomized controlled trial in the Florence district (SAVE study)

PubMed Central

2013-01-01

Background Colorectal cancer (CRC) is the most frequent cancer in Europe. Randomized clinical trials demonstrated that screening with fecal occult blood test (FOBT) reduces mortality from CRC. Accordingly, the European Community currently recommends population-based screening with FOBT. Other screening tests, such as computed tomography colonography (CTC) and optical colonoscopy (OC), are highly accurate for examining the entire colon for adenomas and CRC. Acceptability represents a critical determinant of the impact of a screening program. We designed a randomized controlled trial to compare participation rate and diagnostic yield of FOBT, CTC with computer-aided diagnosis, and OC as primary tests for population-based screening. Methods/Design A total of 14,000 subjects aged 55 to 64 years, living in the Florence district and never screened for CRC, will be randomized in three arms: group 1 (5,000 persons) invited to undergo CTC (divided into: subgroup 1A with reduced cathartic preparation and subgroup 1B with standard bowel preparation); group 2 (8,000 persons) invited to undergo a biannual FOBT for three rounds; and group 3 (1,000 persons) invited to undergo OC. Subjects of each group will be invited by mail to undergo the selected test. All subjects with a positive FOBT or CTC test (that is, mass or at least one polyp ≥6 mm) will be invited to undergo a second-level OC. Primary objectives of the study are to compare the participation rate to FOBT, CTC and OC; to compare the detection rate for cancer or advanced adenomas of CTC versus three rounds of biannual FOBT; to evaluate referral rate for OC induced by primary CTC versus three rounds of FOBT; and to estimate costs of the three screening strategies. A secondary objective of the study is to create a biological bank of blood and stool specimens from subjects undergoing CTC and OC. Discussion This study will provide information about participation/acceptability, diagnostic yield and costs of screening with CTC in comparison with the recommended test (FOBT) and OC.

A categorical structure-activity relationship analysis of the developmental toxicity of antithyroid drugs.

PubMed

Cunningham, Albert R; Carrasquer, C Alex; Mattison, Donald R

2009-01-01

The choice of therapeutic strategies for hyperthyroidism during pregnancy is limited. Surgery and radioiodine are typically avoided, leaving propylthiouracil and methimazole in the US. Carbimazole, a metabolic precursor of methimazole, is available in some countries outside of the US. In the US propylthiouracil is recommended because of concern about developmental toxicity from methimazole and carbimazole. Despite this recommendation, the data on developmental toxicity of all three agents are extremely limited and insufficient to support a policy given the broad use of methimazole and carbimazole around the world. In the absence of new human or animal data we describe the development of a new structure-activity relationship (SAR) model for developmental toxicity using the cat-SAR expert system. The SAR model was developed from data for 323 compounds evaluated for human developmental toxicity with 130 categorized as developmental toxicants and 193 as nontoxicants. Model cross-validation yielded a concordance between observed and predicted results between 79% to 81%. Based on this model, propylthiouracil, methimazole, and carbimazole were observed to share some structural features relating to human developmental toxicity. Thus given the need to treat women with Graves's disease during pregnancy, new molecules with minimized risk for developmental toxicity are needed. To help meet this challenge, the cat-SAR method would be a useful in screening new drug candidates for developmental toxicity as well as for investigating their mechanism of action.

Caenorhabditis elegans: An Emerging Model in Biomedical and Environmental Toxicology

Leung, Maxwell C. K.; Williams, Phillip L.; Benedetto, Alexandre; Au, Catherine; Helmcke, Kirsten J.; Aschner, Michael; Meyer, Joel N.

2008-01-01

The nematode Caenorhabditis elegans has emerged as an important animal model in various fields including neurobiology, developmental biology, and genetics. Characteristics of this animal model that have contributed to its success include its genetic manipulability, invariant and fully described developmental program, well-characterized genome, ease of maintenance, short and prolific life cycle, and small body size. These same features have led to an increasing use of C. elegans in toxicology, both for mechanistic studies and high-throughput screening approaches. We describe some of the research that has been carried out in the areas of neurotoxicology, genetic toxicology, and environmental toxicology, as well as high-throughput experiments with C. elegans including genome-wide screening for molecular targets of toxicity and rapid toxicity assessment for new chemicals. We argue for an increased role for C. elegans in complementing other model systems in toxicological research. PMID:18566021

A major hurdle in using complex systems for drug screening is the difficulty of defining the mechanistic targets of small molecules. The zebrafish provides an excellent model system for juxtaposing developmental phenotypes with mechanism discovery using organism genetics. We carried out a phenotype-based screen of uncharacterized small molecules in zebrafish that produced a variety of chemically induced phenotypes with potential genetic parallels. Specifically, kalihinol F caused an undulated notochord, defects in pigment formation, hematopoiesis, and neural development. These phenotypes were strikingly similar to the zebrafish mutant, calamity, an established model of copper deficiency. Further studies into the mechanism of action of kalihinol F revealed a copper-chelating activity. Our data support this mechanism of action for kalihinol F and the utility of zebrafish as an effective system for identifying therapeutic and target pathways. Copyright © 2013 Elsevier Ltd.

2012-08-01

Poor handwriting has been shown to be associated with developmental disorders such as Developmental Coordination Disorder, Attention Deficit Hyperactivity Disorder, autism, and learning disorders. Handwriting difficulties could lead to academic underachievement and poor self-esteem. Therapeutic intervention has been shown to be effective in treating children with poor handwriting, making early identification critical. The SOS test (Systematic Screening for Handwriting Difficulties) has been developed for this purpose. A child copies a sample of writing within 5 min. Handwriting quality is evaluated using six criteria and writing speed is measured. The Dutch SOS test was administered to 860 Flemish children (7-12 years). Inter- and intrarater reliability was excellent. Test-retest reliability was moderate. A correlation coefficient of 0.70 between SOS and "Concise Assessment Methods of Children Handwriting" test (Dutch version) confirmed convergent validity. The SOS allowed discrimination between typically developing children and children in special education, males and females, and different age groups.

A new selective developmental deficit: Impaired object recognition with normal face recognition.

PubMed

Germine, Laura; Cashdollar, Nathan; Düzel, Emrah; Duchaine, Bradley

2011-05-01

Studies of developmental deficits in face recognition, or developmental prosopagnosia, have shown that individuals who have not suffered brain damage can show face recognition impairments coupled with normal object recognition (Duchaine and Nakayama, 2005; Duchaine et al., 2006; Nunn et al., 2001). However, no developmental cases with the opposite dissociation - normal face recognition with impaired object recognition - have been reported. The existence of a case of non-face developmental visual agnosia would indicate that the development of normal face recognition mechanisms does not rely on the development of normal object recognition mechanisms. To see whether a developmental variant of non-face visual object agnosia exists, we conducted a series of web-based object and face recognition tests to screen for individuals showing object recognition memory impairments but not face recognition impairments. Through this screening process, we identified AW, an otherwise normal 19-year-old female, who was then tested in the lab on face and object recognition tests. AW's performance was impaired in within-class visual recognition memory across six different visual categories (guns, horses, scenes, tools, doors, and cars). In contrast, she scored normally on seven tests of face recognition, tests of memory for two other object categories (houses and glasses), and tests of recall memory for visual shapes. Testing confirmed that her impairment was not related to a general deficit in lower-level perception, object perception, basic-level recognition, or memory. AW's results provide the first neuropsychological evidence that recognition memory for non-face visual object categories can be selectively impaired in individuals without brain damage or other memory impairment. These results indicate that the development of recognition memory for faces does not depend on intact object recognition memory and provide further evidence for category-specific dissociations in visual recognition.

Steinbach, Rosemary J.; Allyse, Megan; Michie, Marsha; Liu, Emily Y.; Cho, Mildred K.

2016-01-01

Recently, new noninvasive prenatal genetic screening technologies for Down syndrome and other genetic conditions have become commercially available. Unique characteristics of these screening tests have reignited long-standing concerns about prenatal testing for intellectual and developmental disabilities. We conducted a web-based survey of a sample of the US public to examine how attitudes towards disability inform views of prenatal testing in the context of these rapidly advancing prenatal genetic screening technologies. Regardless of opinion toward disability, the majority of respondents supported both the availability of screening and the decision to continue a pregnancy positive for aneuploidy. Individuals rationalized their support with various conceptions of disability; complications of the expressivist argument and other concerns from the disability literature were manifested in many responses analyzed.

A cross-sectional pilot study of the Scottish early development instrument: a tool for addressing inequality

PubMed Central

2013-01-01

Background Early childhood is recognised as a key developmental phase with implications for social, academic, health and wellbeing outcomes in later childhood and indeed throughout the adult lifespan. Community level data on inequalities in early child development are therefore required to establish the impact of government early years’ policies and programmes on children’s strengths and vulnerabilities at local and national level. This would allow local leaders to target tailored interventions according to community needs to improve children’s readiness for the transition to school. The challenge is collecting valid data on sufficient samples of children entering school to derive robust inferences about each local birth cohort’s developmental status. This information needs to be presented in a way that allows community stakeholders to understand the results, expediting the improvement of preschool programming to improve future cohorts’ development in the early years. The aim of the study was to carry out a pilot to test the feasibility and ease of use in Scotland of the 104-item teacher-administered Early Development Instrument, an internationally validated measure of children’s global development at school entry developed in Canada. Methods Phase 1 was piloted in an education district with 14 Primary 1 teachers assessing a cohort of 154 children, following which the instrument was adapted for the Scottish context (Scottish Early Development Instrument: SEDI). Phase 2 was then carried out using the SEDI. Data were analysed from a larger sample of 1090 participants, comprising all Primary 1 children within this school district, evaluated by 68 teachers. Results The SEDI displayed adequate psychometric and discriminatory properties and is appropriate for use across Scotland without any further modifications. Children in the lowest socioeconomic status quintiles were 2–3 times more likely than children in the most affluent quintile to score low in at least one developmental domain. Even in the most affluent quintile though, 17% of children were ‘developmentally vulnerable’, suggesting that those in need cannot be identified by socioeconomic status alone. Conclusions The SEDI offers a feasible means of providing communities with a holistic overview of school readiness for targeting early years’ interventions. PMID:24341526

Developmental coordination disorder (DCD) is a motor disorder of unclear etiology that severely interferes with a child's ability to perform daily motor tasks. As a useful alternative to a time-consuming motor test and specialist evaluation, parents or teachers can complete motor questionnaires. A tool used worldwide to screen motor performance in 4- to 14-year-old children is the Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07). To describe how we translated the Developmental Coordination Disorder Questionnaire 2007 (DCDQ'07) and adapted it to the Italian population and to test its preliminary psychometric properties in Italian children. Parents of a clinical group of 26 children (5-11 years old) with a diagnosis of DCD and 52 matched controls completed the DCDQ translated into Italian and adapted for cross-cultural purposes according to current guidelines. Twenty-four parents of typically developing children randomly selected completed the questionnaire twice to examine test-retest reliability. The internal consistency value (Cronbach alpha) for the Italian DCDQ was 0.94. The Italian DCDQ achieved moderate-to-high test-retest reliability (ICC) for 14/15 items and a good diagnostic performance for identifying children with DCD (sensitivity 88% and specificity 96%). The Italian DCDQ is a valid screening tool for assessing motor performance in 5- to 11-year-old children that merits research in a larger sample.

An Investigation to Validate the Grammar and Phonology Screening (GAPS) Test to Identify Children with Specific Language Impairment

PubMed Central

van der Lely, Heather K. J.; Payne, Elisabeth; McClelland, Alastair

2011-01-01

Background The extraordinarily high incidence of grammatical language impairments in developmental disorders suggests that this uniquely human cognitive function is “fragile”. Yet our understanding of the neurobiology of grammatical impairments is limited. Furthermore, there is no “gold-standard” to identify grammatical impairments and routine screening is not undertaken. An accurate screening test to identify grammatical abilities would serve the research, health and education communities, further our understanding of developmental disorders, and identify children who need remediation, many of whom are currently un-diagnosed. A potential realistic screening tool that could be widely administered is the Grammar and Phonology Screening (GAPS) test – a 10 minute test that can be administered by professionals and non-professionals alike. Here we provide a further step in evaluating the validity and accuracy (sensitivity and specificity) of the GAPS test in identifying children who have Specific Language Impairment (SLI). Methods and Findings We tested three groups of children; two groups aged 3;6–6:6, a typically developing (n = 30) group, and a group diagnosed with SLI: (n = 11) (Young (Y)-SLI), and a further group aged 6;9–8;11 with SLI (Older (O)-SLI) (n = 10) who were above the test age norms. We employed a battery of language assessments including the GAPS test to assess the children's language abilities. For Y-SLI children, analyses revealed a sensitivity and specificity at the 5th and 10th percentile of 1.00 and 0.98, respectively, and for O-SLI children at the 10th and 15th percentile .83 and .90, respectively. Conclusions The findings reveal that the GAPS is highly accurate in identifying impaired vs. non-impaired children up to 6;8 years, and has moderate-to-high accuracy up to 9 years. The results indicate that GAPS is a realistic tool for the early identification of grammatical abilities and impairment in young children. A larger investigation is warranted in children with SLI and other developmental disorders. PMID:21829461

The purpose of this study was to compare developmental defects of enamel (DDE) in the primary and permanent dentitions of children from a low-fluoride district. A total of 517 healthy schoolchildren were examined using the modified DDE criteria. The prevalence of DDE in the primary and permanent dentition was 25% and 58%, respectively (P<.001). The mean number of teeth with enamel opacity per subject was approximately threefold compared to that affected by enamel hypoplasia (3.1±3.8 vs 0.8±1.4, P<.001 in the primary dentition and 3.6±4.7 vs 1.2±2.2, P<.001 in the permanent dentition). Demarcated opacities (83%) were predominant compared to diffuse opacities (17%), while missing enamel was the most common type of enamel hypoplasia (50%), followed by grooves (31%) and enamel pits (19%) (P=.04). In the permanent dentition, diffuse and demarcated opacities were equally frequent, while enamel grooves were the commonest type of hypoplasia (52%), followed by missing enamel (35%) and enamel pits (5%; P<.001). In a low-fluoride community, developmental defects of enamel were twice as common in the permanent dentition vs the primary dentition. In the primary dentition, the predominant defects were demarcated opacities and missing enamel, while in the permanent dentition, the defects were more variable.

We conducted a pilot study to assess the feasibility using the Electoral Register to carry out a cervical cancer screening programme on a Health District basis. A random sample of 500 names and addresses were drawn from a computerised list of the Electoral Register from three Electoral Wards in Oxford. A pilot study showed that the Electoral Register could be used successfully in this way and that the proportion of women aged 35-64 years who had a cervical smear examination as a result of the screening initiative was increased by a quarter, from 64% to 79%. The numbers of women involved at each step of the screening process were determined, and these may provide a useful guide to others considering implementing similar schemes.

Screening for Developmental Neurotoxicity Using PC12 Cells: Comparisons of Organophosphates with a Carbamate, an Organochlorine, and Divalent Nickel

Slotkin, Theodore A.; MacKillop, Emiko A.; Ryde, Ian T.; Tate, Charlotte A.; Seidler, Frederic J.

2007-01-01

Background In light of the large number of chemicals that are potential developmental neurotoxicants, there is a need to develop rapid screening techniques. Objectives We exposed undifferentiated and differentiating neuronotypic PC12 cells to different organophosphates (chlorpyrifos, diazinon, parathion), a carbamate (physostigmine), an organochlorine (dieldrin), and a metal (divalent nickel; Ni2+) and examined indices of cell replication and differentiation for both short- and long-term exposures. Results In undifferentiated cells, all the agents inhibited DNA synthesis, with the greatest effect for diazinon, but physostigmine eventually produced the largest deficits in the total number of cells after prolonged exposure. The onset of differentiation intensified the adverse effects on DNA synthesis and changed the rank order in keeping with a shift away from noncholinergic mechanisms and toward cholinergic mechanisms. Differentiation also worsened the effects of each agent on cell number after prolonged exposure, whereas cell growth was not suppressed, nor were there any effects on viability as assessed with trypan blue. Nevertheless, differentiating cells displayed signs of oxidative stress from all of the test compounds except Ni2+, as evidenced by measurements of lipid peroxidation. Finally, all of the toxicants shifted the transmitter fate of the cells away from the cholinergic phenotype and toward the catecholaminergic phenotype. Conclusions These studies point out the feasibility of developing cell-based screening methods that enable the detection of multiple end points that may relate to mechanisms associated with developmental neurotoxicity, revealing some common targets for disparate agents.

2013-01-01

Developmental biology has long benefited from studies of classic model organisms. Recently, human pluripotent stem cells (hPSCs), including human embryonic stem cells and human induced pluripotent stem cells, have emerged as a new model system that offers unique advantages for developmental studies. Here, we discuss how studies of hPSCs can complement classic approaches using model organisms, and how hPSCs can be used to recapitulate aspects of human embryonic development ‘in a dish’. We also summarize some of the recently developed genetic tools that greatly facilitate the interrogation of gene function during hPSC differentiation. With the development of high-throughput screening technologies, hPSCs have the potential to revolutionize gene discovery in mammalian development. PMID:23362344

With aging, there is a parallel increase in the prevalence of dementia worldwide. The aim of this work is to determine the prevalence of dementia among the population of Al Kharga District, New Valley, Egypt. Screening of all subjects aged ≥50 years (n = 8,173 out of 62,583 inhabitants) was done through a door-to-door survey by 3 neurologists, using a short standardized Arabic screening test and a modified Mini-Mental State Examination. Suspected cases were subjected to full clinical examination, psychometric assessment using the Cognitive Abilities Screening Instrument, Instrumental Activities of Daily Living Scale, Geriatric Depression Scale, Hachinski Ischemic Score, DSM-IV-TR diagnostic criteria, neuroimaging, and laboratory investigations, when indicated. The prevalence rate of dementia was 2.26% for the population aged ≥50 years. It increased steeply with age to a maximum of 18.48% for those aged ≥80 years. Alzheimer's disease (51.2%) was the most common subtype, followed by vascular dementia (28.7%), dementia due to general medical conditions (12.8%), and lastly dementia due to multiple etiologies (7.3%). Mild dementia was the commonest (53.7%). Dementia is prevalent in Egypt as elsewhere. Detection through a door-to-door survey is the best method in developing countries for early detection of mild cases. Copyright © 2012 S. Karger AG, Basel.

A cross-sectional study was conducted from May 2016 to January 2017 in Rubavu and Nyabihu districts, Western Rwanda, aiming at estimating the prevalence of subclinical mastitis (SCM) and identifying its causative bacteria. Management practices and milking procedures were recorded through a questionnaire. 123 crossbreed milking cows from 13 dairy farms were randomly selected and screened for SCM using California Mastitis Test (CMT). Composite CMT positive milk samples were processed for bacterial isolation and identification. The overall SCM prevalence at cow level was 50.4%. 68 bacterial isolates were identified by morphological and biochemical characteristics. They included, Coagulase Negative Staphylococci (51.5%), Staphylococcus aureus (20.6%), Streptococcus species (10.3%), Bacillus species (10.3%), Streptococcus agalactiae (5.8%), and Escherichia coli (1.5%). About 67.1% of the farmers checked for mastitis; of these, 58.9% relied on clinical signs and only 6.8% screened with CMT. Only 5.5% and 2.7% of the farmers tried to control mastitis using dry cow therapy and teat dips, respectively. Thus, to reduce the prevalence of SCM, farmers in the study area need to be trained on good milking practices, including regular use of teat dips, application of dry cow therapy, and SCM screening. This will improve their sales and their financial status. PMID:28798952

At present there is no data available on reduced vision and refractive errors in school children of far western Nepal. So, school screening records were used to obtain data useful for planning of refractive services. Data are provided from school screening conducted by Geta Eye Hospital during February/March 2008. The cases with complete data sets on visual acuity, refractive error and age were included and analyzed using computer software. Of 1165 children (mean age 11.6 ± 2.5 years) examined, 98.8% (n = 1151) had uncorrected visual acuity of 6/9 and better in at least one eye whereas 1.2% (n = 14) had acuity 6/12 and worse in both eyes. Among them, either eye of 9 children improved to 6/9 and better with correction. However, visual acuity was 6/12 and worse in both eyes of 5 children even after correction. There were 24 children with refractive errors (myopia, 1.54%; n = 18 and hypermetropia, 0.51%; n = 6) in at least one eye. The spherical equivalent refraction was not significantly different with age and gender. The incidence of reduced vision and refractive errors among school children of this semi rural district were low.

2016-12-01

To investigate whether standardized motor development screening and assessment tools that are used to evaluate motor abilities of children aged 0 to 2 years are valid in cultures other than those in which the normative sample was established. This was a systematic review in which six databases were searched. Studies were selected based on inclusion/exclusion criteria and appraised for evidence level and quality. Study variables were extracted. Twenty-three studies representing six motor development screening and assessment tools in 16 cultural contexts met the inclusion criteria: Alberta Infant Motor Scale (n=7), Ages and Stages Questionnaire, 3rd edition (n=2), Bayley Scales of Infant and Toddler Development, 3rd edition (n=8), Denver Developmental Screening Test, 2nd edition (n=4), Harris Infant Neuromotor Test (n=1), and Peabody Developmental Motor Scales, 2nd edition (n=1). Thirteen studies found significant differences between the cultural context and normative sample. Two studies established reliability and/or validity of standardized motor development assessments in high-risk infants from different cultural contexts. Five studies established new population norms. Eight studies described the cross-cultural adaptation of a standardized motor development assessment. Standardized motor development assessments have limited validity in cultures other than that in which the normative sample was established. Their use can result in under- or over-referral for services. © 2016 Mac Keith Press.

Factors Accounting for a Missed Diagnosis of Cystic Fibrosis After Newborn Screening

Rock, Michael J.; Levy, Hara; Zaleski, Christina; Farrell, Philip M.

2015-01-01

Summary Newborn screening is a public health policy program involving the centralized testing laboratory, infant and their family, primary care provider, and subspecialist for confirmatory testing and follow-up of abnormal results. Cystic fibrosis (CF) newborn screening has now been enacted in all 50 states and the District of Columbia and throughout many countries in the world. Although CF neonatal screening will identify the vast majority of infants with CF, there are many factors in the newborn screening system that can lead to a missed diagnosis of CF. To inform clinicians, this article summarizes the CF newborn screening system and highlights 14 factors that can account for a missed diagnosis of CF. Care providers should maintain a high suspicion for CF if there are compatible symptoms, regardless of the results of the newborn screening test. These factors in newborn screening programs leading to a missed diagnosis of CF present opportunities for quality improvement in specimen collection, laboratory analysis of immunoreactive tryspinogen (IRT) and CF mutation testing, communication, and sweat testing.

Early identification of autism spectrum disorder, intellectual developmental disorder, attention-deficit/hyperactivity disorder, and other neurodevelopmental disorders/problems is crucial, yet diagnosis is often delayed for years under the often misguided "wait-and-see" paradigm. The early symptomatic syndromes eliciting neurodevelopmental clinical examinations-questionnaire (ESSENCE-Q) is a brief (12-item) screening questionnaire developed specifically for the purpose of speeding up the identification process of a wide variety of neurodevelopmental problems. The aims were to 1) estimate the reliability of the ESSENCE-Q, 2) evaluate the clinical cutoff levels suggested by the author of the ESSENCE-Q, and 3) propose optimal cutoff levels based on receiver operating characteristic analysis. The ESSENCE-Q was used for 1 year by a psychiatrist in Kochi, Japan, assessing children under the age of 6 years referred for developmental problems. The children were also clinically assessed with regard to whether or not they met criteria for a developmental disorder (diagnosis positive and diagnosis negative groups). We contrasted the results of the ESSENCE-Q and those of clinical diagnostic assessments in 130 cases. Cronbach's alpha was 0.82, sensitivity was 0.94 (95% confidence interval [CI]: [0.88, 0.98]), and specificity 0.53 (95% CI: [0.28, 0.77]), which are reasonable psychometrics for a first-step screening tool. Based on receiver operating characteristic analysis, we recommended an optimal cutoff level of yes ≥2 or maybe/a little ≥3 on the ESSENCE-Q (0.87 (95% CI: [0.79, 0.92]) sensitivity and 0.77 (95% CI: [0.50, 0.93]) specificity). The ESSENCE-Q can be a good instrument for use as a screening tool for aiding in the process of early identification of neurodevelopmental disorders in clinical settings. To establish the broader validity and reliability of the ESSENCE-Q, case-control studies and general population studies of children in different age groups are needed.

Studies show that ADHD, conduct disorders, and anxiety disorders are clinical disorders mostly diagnosed in schoolstarters. The preschool medical examination in Bremen was therefore extended by behavioral screenings. Based on their screening results from the SEU (health examination for school entry) 2011 in Bremen, 67 preschoolers were tested for behavioral disorders. Subsequently, children with behavioral or emotional symptoms (N = 56) were compared to symptomfree controls (N = 52) for their cognitive, motoric, linguistic, and social-emotional development. Psychosocial health was obtained through external assessment by the parents and kindergarten teachers. Results of the WPPSI-III, M-ABC-2, and ET 6-6 were included in the analysis. 32 children met the criteria for behavioral disorders. Children with behavioral or emotional symptoms showed significant lower scores on tests measuring cognitive, motoric, linguistic and emotional development compared to controls. Results suggest that there is necessity to screen all preschoolers for behavioral disorders before entering school. Because children with clinical or subclinical behavioral disorders showed major developmental deficits compared to children without behavioral symptoms, it is essential to conduct a multiple assessment on children with suspected behavioral disorders to ensure early developmental support and adequate interventional programs.

The Ages and Stages Questionnaires (ASQ) are parent-report screening tools to identify infants at risk of developmental difficulties. The purpose of this study was to examine validity and internal reliability of the fine motor developmental area of the ASQ, 2nd edition (ASQ2-FM) for screening 12-month-old infants following major surgery. The ASQ2-FM was completed by caregivers of 74 infants who had cardiac surgery in the first 90 days of life, 104 infants who had noncardiac surgery in the first 90 days of life, and a control group of 154 infants. The Rasch item response analysis revealed that the ASQ2-FM had poor ability to discriminate among levels of fine motor ability. Sensitivity was poor (20%) and specificity was good (98%) when compared with the scores for the fine motor subscale of the Bayley Scales of Infant and Toddler Development. The ASQ2-FM under-identified infants at risk for fine motor delay; internal reliability and construct validity do not support use as a screening tool of fine motor development of infants aged 12 months who have undergone major surgery.

We have screened for zygotic embryonic lethal mutations affecting cuticular morphology in Nasonia vitripennis (Hymenoptera; Chalcidoidea). Our broad goal was to investigate the use of Nasonia for genetically surveying conservation and change in regulatory gene systems, as a means to understand the diversity of developmental strategies that have arisen during the course of evolution. Specifically, we aim to compare anteroposterior patterning gene functions in two long germ band insects, Nasonia and Drosophila. In Nasonia, unfertilized eggs develop as haploid males while fertilized eggs develop as diploid females, so the entire genome can be screened for recessive zygotic mutations by examining the progeny of F1 females. We describe 74 of >100 lines with embryonic cuticular mutant phenotypes, including representatives of coordinate, gap, pair-rule, segment polarity, homeotic, and Polycomb group functions, as well as mutants with novel phenotypes not directly comparable to those of known Drosophila genes. We conclude that Nasonia is a tractable experimental organism for comparative developmental genetic study. The mutants isolated here have begun to outline the extent of conservation and change in the genetic programs controlling embryonic patterning in Nasonia and Drosophila. PMID:10866651

From 2011 to 2013 in the area of the Naples 3 public health district (ASL-NA3), a colorectal cancer screening program (CCSP) was developed. In order to stress the need of quality assurance procedures for surgery and pathology, a third level oncologic pathway was added and set up at a referral colorectal cancer center (RC). Lymph nodal (LN) harvesting, as a process indicator, and nodal positivity were adopted for an interim analysis. The program was implemented by a series of audit meetings and a double type of multidisciplinary team (MDT): "horizontal" and "vertical." Three hundred and forty colorectal cancer (CRC) patients underwent surgery: 119 chose to be operated at the RC (Gr In), 65 were operated at 22 district hospitals (DH) (Gr Out), and 156 symptomatic not screened patients were operated at the RC (Gr Sym). Statistical analysis revealed differences between Gr In and Gr Out colon groups both for LN harvesting (median of 26 and 11, respectively, P = 0.0001), and for nodal positivity after the first screening round (34.78 and 19.45%, respectively, P = 0.0169). Results were all the more significant in a subset analysis on early T stage colon subgroups (In vs Out) both for LN harvesting (P < 0.0001) and nodal positivity (P < 0.0001). xSignificant differences between RC and DHs were found, particularly for early-stage CRC patients. LN harvesting should be considered as a surrogate marker of quality assurance for at least screening hospitals for "minimum best" standard of care. This should lead to set up a third level in any CCSP.

Assessing the Developmental Neurotoxicity of 27 Organophosphorus Pesticides Using a Zebrafish Behavioral Assay, Waalkes, M., Hunter, D.L., Jarema, K., Mundy, W., and S. Padilla. The U.S. Environmental Protection Agency is evaluating methods to screen and prioritize organophosphorus pesticides for developmental neurotoxicity. As such, we are exploring a behavioral testing paradigm that can assess the effects of sublethal and subteratogenic concentrations of developmental neurotoxicants on zebrafish (Danio rerio). This in vivo assay quantifies the locomotor response to light stimuli under tandem light and dark conditions in a 96-well plate using a video tracking system on 6 day post fertilization zebrafish larvae. Each of twenty-seven organophosphorus pesticides was tested for their developmental neurotoxic potential by exposing zebrafish embryos/larvae to the pesticide at several concentrations (≤ 100 μM nominal concentration) during the first five days of development, followed by 24 hours of depuration and then behavioral testing. Approximately 22% of the chemicals (Acephate, Dichlorvos, Diazoxon, Bensulide,Tribufos, Tebupirimfos) did not produce any behavioral changes after developmental exposure, while many (Malaoxon Fosthiazate, Dimethoate, Dicrotophos, Ethoprop, Malathion, Naled, Diazinon, Methamidophos, Terbufos, Trichlorfon, Phorate, Pirimiphos-methyl, Profenofos, Z-Tetrachlorvinphos, Chlorpyrifos, Coumaphos, Phosmet, Omethoate) produced changes in swi

Atrial fibrillation (AF), the world's most common arrhythmia, often goes undetected and untreated in low-resource communities, including India, where AF epidemiology is undefined. AF is an important risk factor for stroke, which plagues an estimated 1.6 million Indians annually. As such, early detection of AF and management of high-risk patients is critically important to decrease stroke burden in individuals with AF. This study aims to describe the epidemiology of AF in Anand District, Gujarat, India, characterise the clinical profile of individuals who are diagnosed with AF and determine the performance of two mobile technologies for community-based AF screening. This observational study builds on findings from a previous feasibility study and leverages two novel technologies as well as an existing community health programme to perform door-to-door AF screening for 2000 people from 60 villages of Anand District, Gujarat, India using local health workers. A single-lead ECG and a pulse-based application is used to screen each individual for AF three times over a period of 5 days. Participants with suspected arrhythmias are followed up by study cardiologist who makes final diagnoses. Participants diagnosed with AF are initiated on treatment based on current anticoagulation guidelines and clinical reasoning. Age-stratified and sex-stratified prevalence of AF in the Anand District will be calculated for sample and estimated for Anand distribution using survey design weights. Sociodemographic and clinical factors associated with AF will be evaluated using multivariable regression methods. Performance of each mobile technology in detecting AF will be evaluated using a 12-lead ECG interpretation as the gold standard. This protocol was approved separately by the Institutional Review Board of University of Massachusetts Medical School and the Human Research Ethics Committee at Charutar Arogya Mandal. The findings of this study will be disseminated through peer-reviewed journals and scientific conferences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

With the incidence of malaria in Sri Lanka declining, intensive parasitological surveillance has been identified as a key strategy to achieve elimination by end 2014. Tropical and Environmental Diseases and Health Associates Private Limited (TEDHA) in collaboration with the Anti-Malaria Campaign established 43 malaria diagnostic laboratories (MDL) in four post-conflict districts of the Northern and Eastern Provinces. This study assesses the patterns of referral of patients with fever for malaria diagnosis by health care providers (HCPs) in four government hospitals in one of the districts of the Northern Province, and patient satisfaction with the laboratory services offered. In this prospective descriptive study, data was collected on the proportion of fever patients being referred by the HCP in hospitals for malaria screening, and the proportion thereof who underwent screening. An interviewer-administered questionnaire was also used to assess patient satisfaction among those attending MDL, which was graded on a scale of 0-4. Of patients presenting to the hospitals with fever, only 44.3% were referred for malaria screening; 81.7% of them underwent screening. Referral depended largely on the presence of a permanent staff HCP. Satisfaction levels were high, with 86.55% giving an overall rating of 4. Comfort within the laboratory was rated satisfactory in three of the four hospitals. This study demonstrates the success of a public-private partnership in the malaria control programme in Sri Lanka. Malaria is considered low on the differential diagnosis in patients with fever even in previously malaria-endemic areas, due to the declining incidence of malaria and the increase in other febrile illnesses in these areas during the recent past. Private sector run malaria diagnostic services provided free of charge within government hospitals are viable and effective, and had good patient satisfaction ratings. In a country on the brink of eliminating malaria, there should be further emphasis on ensuring that HCPs refer patients for malaria diagnosis, in order to prevent a resurgence of the disease.

The Applied Research Group for Kids (TARGet Kids!) is an ongoing open longitudinal cohort study enrolling healthy children (from birth to 5 years of age) and following them into adolescence. The aim of the TARGet Kids! cohort is to link early life exposures to health problems including obesity, micronutrient deficiencies and developmental problems. The overarching goal is to improve the health of Canadians by optimizing growth and developmental trajectories through preventive interventions in early childhood. TARGet Kids!, the only child health research network embedded in primary care practices in Canada, leverages the unique relationship between children and families and their trusted primary care practitioners, with whom they have at least seven health supervision visits in the first 5 years of life. Children are enrolled during regularly scheduled well-child visits. To date, we have enrolled 5062 children. In addition to demographic information, we collect physical measurements (e.g. height, weight), lifestyle factors (nutrition, screen time and physical activity), child behaviour and developmental screening and a blood sample (providing measures of cardiometabolic, iron and vitamin D status, and trace metals). All data are collected at each well-child visit: twice a year until age 2 and every year until age 10. Information can be found at: http://www.targetkids.ca/contact-us/. PMID:24982016

The present study was devoted to test the validity of the Italian adaptation of the Motor Observation Questionnaire for Teachers (MOQ-T, Schoemaker, Flapper, Reinders-Messelink, & De Kloet, 2008) as a fast screening instrument, based on teachers' ratings, for detecting developmental coordination disorders symptoms and to study its relationship with praxic and visuospatial working memory deficits. In a first study on a large sample of children, we assessed the reliability and structure of the Italian adaptation of the MOQ-T. Results showed a good reliability of the questionnaire and a hierarchical structure with two first-order factors (reflecting motor and handwriting skills), which are influenced by a second-order factor (general motor function) at the top. In a second study, we looked at the external validity of the MOQ-T and found that children with symptoms of Developmental Coordination Disorder (children with high scores on the MOQ-T) also had difficulty reproducing gestures, either imitating others or in response to verbal prompts. Our results also showed that children with high MOQ-T scores had visuospatial WM impairments. The theoretical and clinical implications of these findings are discussed. Copyright © 2014 Elsevier Ltd.

Members of the Teratology Society (established in 1960) were involved in the first governmental developmental and reproductive toxicity testing guidelines (1966) by FDA following the thalidomide epidemic, followed by other national and international governmental testing guidelines. The Segment II (developmental toxicity) study design, described in rodents and rabbits, has evolved with additional enhanced endpoints and better descriptions, mechanistic insights, range-finding studies, and toxico/pharmacokinetic ADME information (especially for pharmaceuticals). Society members were also involved in the development of the current screening assays and tests for endocrine disruptors (beginning in 1996) and are now involved with developing new testing guidelines (e.g., the extended one-generation protocol), and evaluating the current test guidelines and new initiatives under ILSI/HESI sponsorship. New initiatives include ToxCast from the U.S. EPA to screen, prioritize, and predict toxic chemicals by high throughput and high-content in vitro assays, bioinformation, and modeling to reduce (or eliminate) in vivo whole animal studies. Our Society and its journal have played vital roles in the scientific and regulatory accomplishments in birth defects research over the past 50 years and will continue to do so in the future.

To investigate the frequency of developmental defects of enamel (DDE) in children with intellectual disability. Children aged 5-18 years (72 children with intellectual disabilities and 72 controls) were included in the study. All the teeth were screened for developmental defects of enamel using the modified Developmental defects of enamel (mDDE) index. Out of the 72 children with intellectual disabilities in this study, 20 (27.78%) presented dental defects of enamel, compared with 8 (11.11%) of those in the control group, which was considered statistically significant (p = 0.021). The majority of children in both groups had white demarcated opacities. Children in both groups were more likely to have maxillary teeth affected than the mandibular teeth and the asymmetrical demarcated enamel defects were more common than the symmetric ones. Majority of opacities in children in both groups were on the maxillary incisors. Children with intellectual disabilities have more developmental defects of enamel than children in the control group. Enamel defects increase caries risk and cause reduction in enamel mechanical properties leading to restoration failures.

Research over the past two decades has consistently documented the high rates of young children entering the child protective services/child welfare system with developmental and mental health problems. There is an emerging evidence base for the role of early intervention services in improving outcomes for children with developmental and mental health problems in the general population that heavily relies on accurate and appropriate screening and assessment practices. The Child Welfare League of America, the American Academy of Pediatrics, and the American Academy of Child and Adolescent Psychiatry have all published guidelines concerning the importance of comprehensive assessments and appropriate referral to early intervention services for children entering out-of-home care. Recent federal legislation (P.L. 108–36) calls for increased collaboration between child welfare and public agencies to address the developmental and mental health needs of young children in foster care. This paper provides a framework for health, developmental, and mental health professionals seeking to partner with child welfare to develop and implement programs addressing these critical issues.

Delivering eye health services to people in rural areas, especially in fragile, post-conflict countries, is a major challenge. This article reports on the implementation and evaluation of an innovative district-based outreach service. The main project partners were the Timor-Leste Ministry of Health and an international non-government organization, with assistance from a local non-government organization. An eye care nurse in Covalima District, a remote location 178 km from Timor-Leste's capital, Dili, was provided with a motor-bike for transport and regular support for outreach eye services to sub-district facilities. Data collected over the first year of operation were examined and included: services provided, spectacles dispensed, health promotion activities conducted and the cost of providing these. The project was also evaluated for its relevance, effectiveness, efficiency, impact and sustainability. In the first 12 months, 55 outreach visits were conducted across the district's seven sub-districts during which 1405 people received vision screening, and 777 spectacles were dispensed. In addition to meeting the five evaluation criteria, compared with the hospital-based eye clinic the outreach service resulted in significantly greater gender equity among eye health service beneficiaries. This pilot project demonstrates what can be achieved when a Ministry of Health (central and district level) and non-government organizations (international and local) work in partnership to support a dedicated health care provider.

Numeric Estimates of Teratogenic Severity from Embryo-Fetal Developmental Toxicity Studies.

PubMed

Wise, L David

2016-02-01

A developing organism exposed to a toxicant will have a response that ranges from none to severe (i.e., death or malformation). The response at a given dosage may be termed teratogenic (or developmental toxic) severity and is dependent on exposure conditions. Prenatal/embryo-fetal developmental (EFD) toxicity studies in rodents and rabbits are the most consistent and definitive assessments of teratogenic severity, and teratogenesis screening assays are best validated against their results. A formula is presented that estimates teratogenic severity for each group, including control, within an EFD study. The developmental components include embryonic/fetal death, malformations, variations, and mean fetal weight. The contribution of maternal toxicity is included with multiplication factors to adjust for the extent of mortality, maternal body weight change, and other parameters deemed important. The derivation of the formula to calculate teratogenic severity is described. Various EFD data sets from the literature are presented to highlight considerations to the calculation of the various components of the formula. Each score is compared to the concurrent control group to obtain a relative teratogenic severity. The limited studies presented suggest relative scores of two- to

Lower organisms show promise for the screening of neurotoxicants that might target mammalian brain development. Sea urchins use neurotransmitters as embryonic growth regulatory signals, so that adverse effects on neural substrates for mammalian brain development can be studied in this simple organism. We compared the effects of the organophosphate insecticide, chlorpyrifos in sea urchin embryos with those of the monoamine depleter, reserpine, so as to investigate multiple neurotransmitter mechanisms involved in developmental toxicity and to evaluate different therapeutic interventions corresponding to each neurotransmitter system. Whereas reserpine interfered with all stages of embryonic development, the effects of chlorpyrifos did not emerge until the mid-blastula stage. After that point, the effects of the two agents were similar. Treatment with membrane permeable analogs of the monoamine neurotransmitters, serotonin and dopamine, prevented the adverse effects of either chlorpyrifos or reserpine, despite the fact that chlorpyrifos works simultaneously through actions on acetylcholine, monoamines and other neurotransmitter pathways. This suggests that different neurotransmitters, converging on the same downstream signaling events, could work together or in parallel to offset the developmental disruption caused by exposure to disparate agents. We tested this hypothesis by evaluating membrane permeable analogs of acetylcholine and cannabinoids, both of which proved effective against chlorpyrifos- or reserpine-induced teratogenesis. Invertebrate test systems can provide both a screening procedure for mammalian neuroteratogenesis and may uncover novel mechanisms underlying developmental vulnerability as well as possible therapeutic approaches to prevent teratogenesis.

This study compared behavioral presentation of toddlers with autistic spectrum disorders (ASD) and toddlers with global developmental delay (DD) or developmental language disorder (DLD) who display some characteristics of ASD using the diagnostic algorithm items from the Autism Diagnostic Observation Schedule, Generic (ADOS), the Childhood Autism Rating Scale (CARS), and Modified Checklist for Autism in Toddlers (M-CHAT). To date, 195 children have failed the M-CHAT and have been diagnosed with ASD, DD or DLD. Children with ASD had prominent and consistent impairments in socialization skills, especially joint attention skills and were more impaired in some aspects of communication, play, and sensory processing. Children with ASD and children with DD/DLD shared common features, but certain behavioral markers differentiated the two groups.

Well-designed screening assessment instruments that can evaluate child development in public daycare centers represent an important resource to help improve the quality of these programs, as an early detection method for early developmental delay. The Ages and Stages Questionnaire, 3rd edition (ASQ-3), comprises a series of 21 questionnaires designed to screen developmental performance in the domains of communication, gross motor skills, fine motor skills, problem solving, and personal-social ability in children aged 2 to 66 months. The purpose of the present work was to translate and adapt all of the ASQ-3 questionnaires for use in Brazilian public child daycare centers and to explore their psychometric characteristics with both Classical Test Theory and Rating Scale analyses from the Rasch model family. A total of 18 Ages & Stages Questionnaires - Brazilian translation (ASQ-BR) questionnaires administered at intervals from 6 to 60 months of age were analyzed based on primary caregiver evaluations of 45,640 children distributed in 468 public daycare centers in the city of Rio de Janeiro. The results indicated that most of the ASQ-BR questionnaires had adequate internal consistency. Exploratory factor analyses yielded a one-factor solution for each domain of all of the ASQ-BR questionnaires. The only exception was the personal-social domain in some of the questionnaires. Item Response Theory based on Rating Scale analysis (infit and outfit mean squares statistics) indicated that only 44 of 540 items showed misfit problems. In summary, the ASQ-BR questionnaires are psychometrically sound developmental screening instruments that can be easily administered by primary caregivers. Copyright © 2013 Elsevier Ltd.

2016-01-01

Background: After the Great East Japan Earthquake and Tsunami in March 2011, radioactive elements were released from the Fukushima Daiichi Nuclear Power Plant. Based on prior knowledge, concern emerged about whether an increased incidence of thyroid cancer among exposed residents would occur as a result. Methods: After the release, Fukushima Prefecture performed ultrasound thyroid screening on all residents ages ≤18 years. The first round of screening included 298,577 examinees, and a second round began in April 2014. We analyzed the prefecture results from the first and second round up to December 31, 2014, in comparison with the Japanese annual incidence and the incidence within a reference area in Fukushima Prefecture. Results: The highest incidence rate ratio, using a latency period of 4 years, was observed in the central middle district of the prefecture compared with the Japanese annual incidence (incidence rate ratio = 50; 95% confidence interval [CI] = 25, 90). The prevalence of thyroid cancer was 605 per million examinees (95% CI = 302, 1,082) and the prevalence odds ratio compared with the reference district in Fukushima Prefecture was 2.6 (95% CI = 0.99, 7.0). In the second screening round, even under the assumption that the rest of examinees were disease free, an incidence rate ratio of 12 has already been observed (95% CI = 5.1, 23). Conclusions: An excess of thyroid cancer has been detected by ultrasound among children and adolescents in Fukushima Prefecture within 4 years of the release, and is unlikely to be explained by a screening surge.

In special circumstances, establishing public private partnerships for malaria elimination may achieve targets faster than the state sector acting by itself. Following the end of the separatist war in Sri Lanka in 2009, the Anti Malaria Campaign (AMC) of Sri Lanka intensified malaria surveillance jointly with a private sector partner, Tropical and Environmental Diseases and Health Associates Private Limited (TEDHA) with a view to achieving malaria elimination targets by 2014. This is a case study on how public private partnerships can be effectively utilized to achieve malaria elimination goals. TEDHA established 50 Malaria Diagnostic Laboratories and 17 entomology surveillance sentinel sites in consultation with the AMC in areas difficult to access by government officials (five districts in two provinces affected by war). TEDHA screened 994,448 individuals for malaria, of which 243,867 were screened at mobile malaria clinics as compared to 1,102,054 screened by the AMC. Nine malaria positives were diagnosed by TEDHA, while the AMC diagnosed 103 malaria cases in the same districts in parallel. Over 13,000 entomological activity days were completed. Relevant information was shared with AMC and the data recorded in the health information system. A successful public-private partnership model for malaria elimination was initiated at a time when the health system was in disarray in war ravaged areas of Sri Lanka. This ensured a high annual blood examination rate and screening of vulnerable people in receptive areas. These were important for certification of malaria-free status which Sri Lanka eventually received in 2016.

To identify the efficacy of the Bayley Scales of Infant and Toddler Development, Third Edition (BSID-III), Screening Test-Gross Motor Subtest (GMS) in identifying infants who are accepted for early intervention services. This retrospective study included 93 infants with a neonatal intensive care experience who participated in a 6-month developmental assessment follow-up visit. All infants were examined using the BSID-III Screening Test-GMS and the Alberta Infant Motor Scale. A binary logical regression analysis was used to determine the best predictors of acceptance status in this sample. The BSID-III Screening Test-GMS accounted for a significant portion of the variance in acceptance status. The results suggest that the BSID-III Screening Test-GMS has great applicability for transdisciplinary/interdisciplinary teams as it effectively identified children who were eligible for early intervention.

New US Preventive Services Task Force (USPSTF) recommendation on screening for autism spectrum disorder (ASD) in young children. The USPSTF reviewed the evidence on the accuracy, benefits, and potential harms of brief, formal screening instruments for ASD administered during routine primary care visits and the benefits and potential harms of early behavioral treatment for young children identified with ASD through screening. This recommendation applies to children aged 18 to 30 months who have not been diagnosed with ASD or developmental delay and for whom no concerns of ASD have been raised by parents, other caregivers, or health care professionals. The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for ASD in young children for whom no concerns of ASD have been raised by their parents or a clinician.

To investigate the effects of touch-screen tablet use on the fine motor development of preschool children without developmental delay. 40 children who used a touch-screen tablet more 60 minutes per week for at least 1 month received a 24-week home fine motor activity program using a touch-screen-tablet. 40 children matched for age (mean = 61.0 months) and sex who did not meet the criteria for previous tablet use received a 24-week program consisting of manual play activities. Motor performance was measured using the Bruininks-Oseretsky Test of Motor Proficiency. The two-factor mixed design ANOVA was used to compare performance of the touch-screen tablet and non-touch-screen tablet groups. Pretest analysis showed no group differences in motor performance and pinch strength. At posttest, children in the nontouch-screen-tablet group made significantly greater changes in fine motor precision (p < 0.001), fine motor integration (p = 0.008), and manual dexterity (p = 0.003). Using a touch screen tablet extensively might be disadvantageous for the fine motor development of preschool children.

Pediatric HIV is poised to become a major public health problem in India with the rising trend of HIV infection in pregnant women (Department of AIDS Control, Ministry of Health and Family Welfare, http://www.naco.gov.in). There is lack of information on the epidemiology of pediatric HIV infection in India. Existing surveillance systems tend to underestimate the Pediatric burden. The overall aim of the present study is to estimate the disease burden of pediatric HIV among children in Belgaum district in the state of Karnataka in Southern India. An innovative multipronged epidemiological approach to comb the district is proposed. The primary objectives of the study would be attained under three strategies. A prospective cohort design for objective (i) to determine the incidence rate of HIV by early case detection in infants and toddlers (0-18 months) born to HIV infected pregnant women; and cross sectional design for objectives (ii) to determine the prevalence of HIV infection in children (0-14 years) of HIV infected parents and (iii) to determine the prevalence of HIV in sick children (0-14 years) presenting with suspected signs and symptoms using age specific criteria for screening. Burden of pediatric HIV will be calculated as a product of cases detected in each strategy multiplied by a net inflation factor for each strategy. Study participants (i) (ii) (iii): HIV infected pregnant women and their live born children (ii) Any HIV-infected man/woman, of age 18-49 years, having a biological child of age 0-14 years (iii) Sick children of age 0-14 years presenting with suspected signs and symptoms and satisfying age-specific criteria for screening. Setting and conduct: Belgaum district which is a Category 'A' district (with more than 1 % antenatal prevalence in the district over the last 3 years before the study). Age-appropriate testing is used to detect HIV infection. There is a need to strengthen existing pediatric HIV estimation methods in India and other developing countries. We hope that the novel methodology emanating from this study would be applicable for estimating the burden of HIV in other settings and it would be adaptable for estimating the burden of other infectious/chronic diseases. Findings from this study will give future direction to the national program for prevention and control of HIV in India and other developing countries.

To evaluate the frequency of developmental dental anomalies in the Indian population. This prospective study was conducted over a period of 1 year and comprised both clinical and radiographic examinations in oral medicine and radiology outpatient department. Adult patients were screened for the presence of dental anomalies with appropriate radiographs. A comprehensive clinical examination was performed to detect hyperdontia, talon cusp, fused teeth, gemination, concrescence, hypodontia, dens invaginatus, dens evaginatus, macro- and microdontia and taurodontism. Patients with syndromes were not included in the study. Of the 20,182 patients screened, 350 had dental anomalies. Of these, 57.43% of anomalies occurred in male patients and 42.57% occurred in females. Hyperdontia, root dilaceration, peg-shaped laterals (microdontia), and hypodontia were more frequent compared to other dental anomalies of size and shape. Dental anomalies are clinically evident abnormalities. They may be the cause of various dental problems. Careful observation and appropriate investigations are required to diagnose the condition and institute treatment.

Creatine transporter deficiency (CTD) is an example of X-linked intellectual disability syndromes, caused by mutations in SLC6A8 on Xq28. Although this is the second most frequent genetic cause of intellectual disabilities in Europe or America after Fragile X syndrome, information on the morbidity of this disease is limited in Japan. Using the HPLC screening method we have established recently, we examined samples of urine of 105 patients (73 males and 32 females) with developmental disabilities at our medical center. And we have found a family with three ID boys with a novel missense mutation in SLC6A8. This is the second report of a Japanese family case of CTD. A systematic diagnostic system of this syndrome should be established in Japan to enable us to estimate its frequency and treatment. Copyright © 2013 The Japanese Society of Child Neurology.

Making Waves: New Developments in Toxicology With the Zebrafish.

PubMed

Horzmann, Katharine A; Freeman, Jennifer L

2018-05-01

The laboratory zebrafish (Danio rerio) is now an accepted model in toxicologic research. The zebrafish model fills a niche between in vitro models and mammalian biomedical models. The developmental characteristics of the small fish are strategically being used by scientists to study topics ranging from high-throughput toxicity screens to toxicity in multi- and transgenerational studies. High-throughput technology has increased the utility of zebrafish embryonic toxicity assays in screening of chemicals and drugs for toxicity or effect. Additionally, advances in behavioral characterization and experimental methodology allow for observation of recognizable phenotypic changes after xenobiotic exposure. Future directions in zebrafish research are predicted to take advantage of CRISPR-Cas9 genome editing methods in creating models of disease and interrogating mechanisms of action with fluorescent reporters or tagged proteins. Zebrafish can also model developmental origins of health and disease and multi- and transgenerational toxicity. The zebrafish has many advantages as a toxicologic model and new methodologies and areas of study continue to expand the usefulness and application of the zebrafish.

Objective To evaluate the construct validity of the Behavioral Health Checklist (BHCL) for children aged from 4 to 12 years from diverse backgrounds. Method The parents of 4–12-year-old children completed the BHCL in urban and suburban primary care practices affiliated with a tertiary-care children’s hospital. Across practices, 1,702 were eligible and 1,406 (82.6%) provided consent. Children of participating parents were primarily non-Hispanic black/African American and white/Caucasian from low- to middle-income groups. Confirmatory factor analyses examined model fit for the total sample and subsamples defined by demographic characteristics. Results The findings supported the hypothesized 3-factor structure: Internalizing Problems, Externalizing Problems, and Inattention/Hyperactivity. The model demonstrated adequate to good fit across age-groups, gender, races, income groups, and suburban versus urban practices. Conclusion The findings provide strong evidence of the construct validity, developmental appropriateness, and cultural sensitivity of the BHCL when used for screening in primary care.

Background: Understanding health risks to embryonic development from exposure to environmental chemicals is a significant challenge given the diverse chemical landscape and paucity of data for most of these compounds. High-throughput screening (HTS) in the U.S. Environmental Protection Agency (EPA) ToxCast™ project provides vast data on an expanding chemical library currently consisting of > 1,000 unique compounds across > 500 in vitro assays in phase I (complete) and Phase II (under way). This public data set can be used to evaluate concentration-dependent effects on many diverse biological targets and build predictive models of prototypical toxicity pathways that can aid decision making for assessments of human developmental health and disease. Objective: We mined the ToxCast phase I data set to identify signatures for potential chemical disruption of blood vessel formation and remodeling. Methods: ToxCast phase I screened 309 chemicals using 467 HTS assays across nine assay technology platforms. The assays measured direct interactions between chemicals and molecular targets (receptors, enzymes), as well as downstream effects on reporter gene activity or cellular consequences. We ranked the chemicals according to individual vascular bioactivity score and visualized the ranking using ToxPi (Toxicological Priority Index) profiles. Results: Targets in inflammatory chemokine signaling, the vascular endothelial growth factor pathway, and the plasminogen-activating system were strongly perturbed by some chemicals, and we found positive correlations with developmental effects from the U.S. EPA ToxRefDB (Toxicological Reference Database) in vivo database containing prenatal rat and rabbit guideline studies. We observed distinctly different correlative patterns for chemicals with effects in rabbits versus rats, despite derivation of in vitro signatures based on human cells and cell-free biochemical targets, implying conservation but potentially differential contributions of developmental pathways among species. Follow-up analysis with antiangiogenic thalidomide analogs and additional in vitro vascular targets showed in vitro activity consistent with the most active environmental chemicals tested here. Conclusions: We predicted that blood vessel development is a target for environmental chemicals acting as putative vascular disruptor compounds (pVDCs) and identified potential species differences in sensitive vascular developmental pathways.

Critical congenital heart disease (CCHD) is endorsed by the US Secretary of Health and Human Services as part of the recommended uniform screening panel for newborns. Although initial recommendations for implementation exist, as states and hospitals have moved forward with implementation of screening, new challenges and areas for additional focus have been identified. The objective of this study was to develop recommendations to address current challenges and areas of focus surrounding CCHD newborn screening. A workgroup of experts and stakeholders was convened in Washington, District of Columbia, for a 1-day meeting in February 2012. At the beginning of the meeting, the stakeholders held a brainstorming session to identify areas of main priority based on their experience. After this, stakeholders broke into small groups to refine recommendations, which were then finalized by consensus. Recommendations to address selection of screening equipment, standards for reporting of screening outcomes to stakeholders, training of health care providers and educating families, future research priorities, payment for screening, follow-up diagnostic testing, and public health oversight, and advocacy to facilitate effective and comprehensive screening were proposed. Suggestions for future work were developed. Screening for CCHD presents novel challenges and opportunities; however, addressing these will strengthen newborn screening and newborn care networks, and ultimately improve health outcomes.

Visceral leishmaniasis (VL) is a major vector-borne disease caused by Leishmania donovani, after replication of the parasites in macrophages, mononuclear phagocytic system. VL is endemic in 12 districts of central and eastern Terai lowlands of Nepal bordering North Bihar, India with an estimated 8 million population at risk. In addition, VL endemicity is also extending to new endemic regions like Dharan from its classical rural foci. Hence, we aimed to detect the evidence of Leishmania donovani infection in the blood samples received from blood donors of Sunsari district, Dharan, (eastern Nepal), a region endemic for human VL. Sera from 507 asymptomatic blood donors were subjected to serological screening for anti-Leishmania donovani antibodies. Direct agglutination test (DAT) was performed on the sera. Out of 507 donors, majority (78.50 %) were male. Among the donors, 472 (93.10 %) belonged to age group 18-45 years where as 35 (6.90 %) to age group >45 years. Circulating anti-Leishmania antibodies were detected in 5 (1 %) out of 507 healthy, Human Immunodeficiency Virus types 1 and 2 (HIV 1and 2), Hepatitis B Surface Antigen (HBsAg), anti- Hepatitis C Virus (anti-HCV)-negative, and Syphillis non-reactive donors. All the seropositive cases were male and belonged to the age group 18-45 years. The result suggests that there is an immediate need of screening asymptomatic blood donors for leishmania seropositivity especially in endemic areas.

Goats are the Pakistan's fastest growing ruminants, and Pakistan is the third largest goat producer in the world after India and China. Goat meat preference is the main reason for its increased demand. In the country, there are 25 goat breeds and two wild relatives such as Mark and Goats. At present, Pakistan has 53.8 million goats, according to the 2006 GOP report, and their population growth rate was more than 3% per year (37, 23, 22, and 18% of the goat population in Punjab, Sindh, Balochistan, and NWFP, respectively). Peste des petits ruminants virus (PPRV) belongs to the family Paramyxoviridae and is considered to be one of the major constraints on increasing the productivity of goats and sheep in the areas where they exist and become local. It is closely related to cattle and buffalo rinderpest virus, dogs and other wild predator distemper virus, human measles virus, and marine mammalian measles virus. The present study aimed to determine the screening of the PPRV, Capra Hircus Lin. population, in the Khairpur Mirs District, Sindh, Pakistan. We selected 290 goats for serum sample collection and analysis using competitive ELISA kits according to the manufacturer's instructions. Our results showed that 59 (64%) of the 92 clinical cases were positive and 33 (36%) were seronegative. The study concluded that PPR might be more prevalent in the Khairpur District. Furthermore, it is highly recommended to use homologous PPR-attenuated vaccines to prevent lethal virus attacks that control PPR in the country.

Individuals with autism put a heavy demand on medical services, and prevalence estimates are needed for the planning of such services. Screening for autism in children has important implications for individuals and policy makers. This study aimed to estimate prevalence of suspected autism in children in Longhua District, Shenzhen, and to investigate risk factors for autism. A cross-sectional study was conducted in Longhua District, Shenzhen in October 2014. A total of 141 kindergartens were approached and consented to participate in the current study. All children who met the inclusion criteria were screened for autism by using the Autism Behavior Checklist (ABC). 15,200 children in total completed the survey and were included in the final analysis. 2.6 % (95 % CI 2.3-2.9) respondents had a high probability of autism, while 4.0 % (95 % CI 3.7-4.3) respondents had questionable autism. Male children were more likely to develop autism when compared with their female counterparts (P < 0.001). Children of mothers with a lower education level and younger age tended to develop autism (P < 0.001). Our study shows a high prevalence rate of suspected autism in children which suggests an urgent need of early detection of autism with ABC across the Shenzhen city, or even around China. Further studies with diagnostic procedure are warranted. Maternal age and education level, and gender of children are possible factors related to autism.

Objectives This study aimed to estimate the percentages of attention deficit and hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in Taiwanese aboriginal preschool children. Child development level was compared between the two groups. Methods Teachers completed screening questionnaires for ADHD, ASD, and development level for 36- to 72-month-old children in kindergartens in Taiwan. The questionnaire results were compared between the aboriginal and nonaboriginal children. One child psychiatrist then interviewed the aboriginal preschool children to determine if they had ADHD and/or ASD. Results We collected 93 questionnaires from the aboriginal group and 60 from the nonaboriginal group. In the aboriginal group, 5.37% of the children were identified to have ADHD, while 1.08% were identified to have ASD. Significantly fewer aboriginal children had developmental delays for situation comprehension and personal–social development (P=0.012 and 0.002, respectively) than nonaboriginal children. Conclusion Aboriginal children in Taiwan had typical percentages of ADHD and ASD compared to those published in the literature. Aboriginal children showed relative strengths in situation comprehension and personal–social skills. Further studies are required to understand the learning styles of the aboriginal children and to develop effective screening and intervention strategies for ADHD and ASD. PMID:27785028

Hydraulic-fracturing fluids and wastewater from unconventional oil and natural gas development contain hundreds of substances with the potential to contaminate drinking water. Challenges to conducting well-designed human exposure and health studies include limited information about likely etiologic agents. We systematically evaluated 1021 chemicals identified in hydraulic-fracturing fluids (n=925), wastewater (n=132), or both (n=36) for potential reproductive and developmental toxicity to triage those with potential for human health impact. We searched the REPROTOX database using Chemical Abstract Service registry numbers for chemicals with available data and evaluated the evidence for adverse reproductive and developmental effects. Next, we determined which chemicals linked to reproductive or developmental toxicity had water quality standards or guidelines. Toxicity information was lacking for 781 (76%) chemicals. Of the remaining 240 substances, evidence suggested reproductive toxicity for 103 (43%), developmental toxicity for 95 (40%), and both for 41 (17%). Of these 157 chemicals, 67 had or were proposed for a federal water quality standard or guideline. Our systematic screening approach identified a list of 67 hydraulic fracturing-related candidate analytes based on known or suspected toxicity. Incorporation of data on potency, physicochemical properties, and environmental concentrations could further prioritize these substances for future drinking water exposure assessments or reproductive and developmental health studies.

A Large-Scale Genetic Screen in Arabidopsis to Identify Genes Involved in Pollen Exine Production1[C][W][OA

Exine, the outer plant pollen wall, has elaborate species-specific patterns, provides a protective barrier for male gametophytes, and serves as a mediator of strong and species-specific pollen-stigma adhesion. Exine is made of sporopollenin, a material remarkable for its strength, elasticity, and chemical durability. The chemical nature of sporopollenin, as well as the developmental mechanisms that govern its assembly into diverse patterns in different species, are poorly understood. Here, we describe a simple yet effective genetic screen in Arabidopsis (Arabidopsis thaliana) that was undertaken to advance our understanding of sporopollenin synthesis and exine assembly. This screen led to the recovery of mutants with a variety of defects in exine structure, including multiple mutants with novel phenotypes. Fifty-six mutants were selected for further characterization and are reported here. In 14 cases, we have mapped defects to specific genes, including four with previously demonstrated or suggested roles in exine development (MALE STERILITY2, CYP703A2, ANTHER-SPECIFIC PROTEIN6, TETRAKETIDE α-PYRONE REDUCTASE/DIHYDROFLAVONOL-4-REDUCTASE-LIKE1), and a number of genes that have not been implicated in exine production prior to this screen (among them, fatty acid ω-hydroxylase CYP704B1, putative glycosyl transferases At1g27600 and At1g33430, 4-coumarate-coenzyme A ligase 4CL3, polygalacturonase QUARTET3, novel gene At5g58100, and nucleotide-sugar transporter At5g65000). Our study illustrates that morphological screens of pollen can be extremely fruitful in identifying previously unknown exine genes and lays the foundation for biochemical, developmental, and evolutionary studies of exine production.

Background Living organisms are continuously confronted with perturbations, such as environmental changes that include fluctuations in temperature and nutrient availability, or genetic changes such as mutations. While some developmental systems are affected by such challenges and display variation in phenotypic traits, others continue consistently to produce invariable phenotypes despite perturbation. This ability of a living system to maintain an invariable phenotype in the face of perturbations is termed developmental robustness. Biological robustness is a phenomenon observed across phyla, and studying its mechanisms is central to deciphering the genotype–phenotype relationship. Recent work in yeast, animals and plants has shown that robustness is genetically controlled and has started to reveal the underlying mechinisms behind it. Scope and Conclusions Studying biological robustness involves focusing on an important property of developmental traits, which is the phenotypic distribution within a population. This is often neglected because the vast majority of developmental biology studies instead focus on population aggregates, such as trait averages. By drawing on findings in animals and yeast, this Viewpoint considers how studies on plant developmental robustness may benefit from strict definitions of what is the developmental system of choice and what is the relevant perturbation, and also from clear distinctions between gene effects on the trait mean and the trait variance. Recent advances in quantitative developmental biology and high-throughput phenotyping now allow the design of targeted genetic screens to identify genes that amplify or restrict developmental trait variance and to study how variation propagates across different phenotypic levels in biological systems. The molecular characterization of more quantitative trait loci affecting trait variance will provide further insights into the evolution of genes modulating developmental robustness. The study of robustness mechanisms in closely related species will address whether mechanisms of robustness are evolutionarily conserved. PMID:26292993
