    Three major components have been repeatedly implicated for the origin(s) of sudden infant death syndrome (SIDS): system, minor sickness and surroundings. All these factors also frame infant temperament, and therefore it seems logical to suppose that the babies who either succumb to or are at risk of SIDS may present with certain behavioral…

    Objective To assess risk factors for macrosomic infant birth among Latina women. Study Design Prospective study of Latina women recruited during pregnancy from prenatal clinic at San Francisco General Hospital. Information was obtained through a structured interview and review of medical records. Result A total of 11% of women delivered macrosomic infants (birth weight >4000 g). In unadjusted analyses, significant risk factors for macrosomia included older maternal age, increasing gravidity, previous history of macrosomic birth and pre-pregnancy overweight. After adjusting for confounders using multivariate analyses, older mothers (10-year increments) had an elevated risk of macrosomia (odds ratio (OR) 2.59; 95% confidence interval (CI) 1.28 to 5.24). Conclusion Efforts to reduce macrosomia in Latina women should focus on older mothers. PMID:18596709

    Full Text Available Abstract Background Child maltreatment and its consequences are a persistent problem throughout the world. Public health workers, human services officials, and others are interested in new and efficient ways to determine which geographic areas to target for intervention programs and resources. To improve assessment efforts, selected perinatal factors were examined, both individually and in various combinations, to determine if they are associated with increased risk of infant maltreatment. State of Georgia birth records and abuse and neglect data were analyzed using an area-based, ecological approach with the census tract as a surrogate for the community. Cartographic visualization suggested some correlation exists between risk factors and child maltreatment, so bivariate and multivariate regression were performed. The presence of spatial autocorrelation precluded the use of traditional ordinary least squares regression, therefore a spatial regression model coupled with maximum likelihood estimation was employed. Results Results indicate that all individual factors or their combinations are significantly associated with increased risk of infant maltreatment. The set of perinatal risk factors that best predicts infant maltreatment rates are: mother smoked during pregnancy, families with three or more siblings, maternal age less than 20 years, births to unmarried mothers, Medicaid beneficiaries, and inadequate prenatal care. Conclusion This model enables public health to take a proactive stance, to reasonably predict areas where poor outcomes are likely to occur, and to therefore more efficiently allocate resources. U.S. states that routinely collect the variables the National Center for Health Statistics (NCHS defines for birth certificates can easily identify areas that are at high risk for infant maltreatment. The authors recommend that agencies charged with reducing child maltreatment target communities that demonstrate the perinatal risks

    Full Text Available Abstract Infant sibling studies have been at the vanguard of autism spectrum disorders (ASD research over the past decade, providing important new knowledge about the earliest emerging signs of ASD and expanding our understanding of the developmental course of this complex disorder. Studies focused on siblings of children with ASD also have unrealized potential for contributing to ASD etiologic research. Moving targeted time of enrollment back from infancy toward conception creates tremendous opportunities for optimally studying risk factors and risk biomarkers during the pre-, peri- and neonatal periods. By doing so, a traditional sibling study, which already incorporates close developmental follow-up of at-risk infants through the third year of life, is essentially reconfigured as an enriched-risk pregnancy cohort study. This review considers the enriched-risk pregnancy cohort approach of studying infant siblings in the context of current thinking on ASD etiologic mechanisms. It then discusses the key features of this approach and provides a description of the design and implementation strategy of one major ASD enriched-risk pregnancy cohort study: the Early Autism Risk Longitudinal Investigation (EARLI.

    Cuba is a unique country, and despite limited economic development, has an excellent health system. However, the prevalence of asthma symptoms in children in Havana, Cuba, is unusually high. As early life exposures are critical to the aetiology of asthma, we have studied environmental influences on the risk of wheezing in Cuban infants. Cross-sectional study. A random sample of 2032 children aged 12-15 months living in Havana was selected for inclusion in the cohort. Data were collected using questionnaires administered by researchers. Of 2032 infants invited to participate, 1956 (96%) infants provided data. The prevalence of any wheeze was 45%, severe wheeze requiring use of emergency services was 30% and recurrent wheeze on three or more occasions was 20%. The largest adjusted risk factors for any wheeze were presence of eczema [odds ratio (OR) 2.09; 95% confidence interval (CI) 1.48-2.94], family history of asthma (OR 2.05; 95% CI 1.60-2.62), poor ventilation in the house (OR 1.99; 95% CI 1.48-2.67), attendance at nursery (OR 1.78; 95% CI 1.24-2.57), male sex (OR1.52; 95% CI 1.19-1.96) and the number of smokers in the house (P Cuba. As the prevalence of smoking in the house is high (51%), intervention studies are required to determine effective strategies to improve infant health.

    Infant developmental delays have been associated with several risk factors, such as familial environmental, individual and demographic characteristics. The goal of this study was to longitudinally investigate the effects of maternal knowledge and practices, home environment and biological factors on infant motor and cognitive outcomes. This was a prospective cohort study with a sample of 49 infants from Southern Brazil. The infants were assessed three times over 4 months using the Alberta Infant Motor Scale and the Bayley Scale of Infant Development (Mental Development Scale). Parents completed the Daily Activities Scale of Infants, the Affordances in The Home Environment for Motor Development - Infant Scale, the Knowledge of Infant Development Inventory and a demographic questionnaire. Generalized estimating equation with Bonferroni method as the follow-up test and Spearman correlation and multivariate linear backward regression were used. Cognitive and motor scores were strongly associated longitudinally and increased over time. Associations between the home affordances, parental practices and knowledge, and motor and cognitive development over time were observed. This relationship explained more variability in motor and cognitive scores compared with biological factors. Variability in motor and cognitive development is better explained by environment and parental knowledge and practice. The investigation of factors associated with infant development allows the identification of infants at risk and the implementation of educational programs and parental training to minimize the effects of developmental delay. © 2016 Japan Pediatric Society.

    Full Text Available Abstract Background The northern territory Nunavut has Canada’s largest jurisdictional land mass with 33,322 inhabitants, of which 85% self-identify as Inuit. Nunavut has rates of infant mortality, postneonatal mortality and hospitalisation of infants for respiratory infections that greatly exceed those for the rest of Canada. The infant mortality rate in Nunavut is 3 times the national average, and twice that of the neighbouring territory, the Northwest Territories. Nunavut has the largest Inuit population in Canada, a population which has been identified as having high rates of Sudden Infant Death Syndrome (SIDS and infant deaths due to infections. Methods To determine the causes and potential risk factors of infant mortality in Nunavut, we reviewed all infant deaths ( Results Sudden death in infancy (SIDS/SUDI; 48% and infection (21% were the leading causes of infant death, with rates significantly higher than for Canada (2003–2007. Of SIDS/SUDI cases with information on sleep position (n=42 and bed-sharing (n=47, 29 (69% were sleeping non-supine and 33 (70% were bed-sharing. Of those bed-sharing, 23 (70% had two or more additional risk factors present, usually non-supine sleep position. CPT1A P479L homozygosity, which has been previously associated with infant mortality in Alaska Native and British Columbia First Nations populations, was associated with unexpected infant death (SIDS/SUDI, infection throughout Nunavut (OR:3.43, 95% CI:1.30-11.47. Conclusion Unexpected infant deaths comprise the majority of infant deaths in Nunavut. Although the CPT1A P479L variant was associated with unexpected infant death in Nunavut as a whole, the association was less apparent when population stratification was considered. Strategies to promote safe sleep practices and further understand other potential risk factors for infant mortality (P479L variant, respiratory illness are underway with local partners.

    Diarrhea-associated deaths among US children increased from the mid-1980s through 2006, particularly among infants. Understanding risk factors for diarrhea-associated death could improve prevention strategies. Records of singleton infants with diarrhea listed anywhere on the death certificate were selected from the US Linked Birth/Infant Death data for the period, 2005 to 2007; characteristics of these infants were compared with those of infants who survived their first year. During 2005 to 2007, 1087 diarrhea-associated infant deaths were reported; 86% occurred among low birth weight (LBW, risk ratio: 91.9, 95% confidence interval: 77.4-109.0) and younger median age at death (7 versus 15 weeks, Pdiarrhea-associated death among LBW and NBW infants were sepsis (26%) and volume depletion (20%), respectively. Among LBW infants, 97% of diarrhea-associated deaths occurred in inpatient settings, whereas 27% of NBW infant deaths occurred in outpatient settings and 5.3% in the decedent's home. Male sex, black race, unmarried status and low 5-minute Apgar score (diarrhea-associated morality should focus on understanding and improving management of diarrhea in vulnerable LBW infants. For prevention of diarrhea-associated deaths in NBW infants, educating mothers who fit the high-risk profile regarding home hydration therapy and timely access to medical treatment is important.

    Urinary tract infection (UTI) frequently recurs and increases the risk of renal scarring even in infants with normal urinary tracts. Our study was aimed to find preventive measures for recurrent UTI in these infants. One-hundred ninety infants, who were diagnosed with their first febrile UTI and were proven to have normal urinary systems, were enrolled. We investigated the incidence of recurrent UTI during the following year and the following risk factors: gender, young age, phimosis, vaginal reflux, and acute pyelonephritis (APN) diagnosed by 99m-technetium dimercaptosuccinic acid ((99m)Tc-DMSA)(+) scintigraphy. The incidence of recurrent UTI was 21.1%. The difference in recurrence rate according to gender was not significant. The recurrence rate in infants less than 6 months of age was 25.8%, which was significantly higher than the 7.7% in older infants (P = 0.045). In male infants with persistent non-retractile prepuces, recurrent UTI developed in 34.0%, which was significantly higher than the 17.6% in male infants with retractile prepuces (P = 0.022). The presence of APN in male infants increased the likelihood of recurrent UTI when analyzed by multivariate logistic regression [odds ratio 4.6, 95% confidence interval (95% CI) 1.6-13.0, P = 0.003]. The presence of vaginal reflux and APN in female infants gave no significant difference to the incidence of recurrent UTI. In infants with normal urinary systems, age less than 6 months, non-retractile prepuces and APN in male infants, were the most important risk factors for recurrent UTIs. It is suggested that non-retractile prepuces should be adequately treated to become retractile in young male infants with APN.

    AIM: To assess the incidence of infantile colic and its association with variable predictors in infants born in a community maternity hospital, Tehran, Iran.METHODS: In this prospective cohort study, mothers who gave birth to live newborns between February 21 and March 20, 2003 at the hospital were invited to join to the study. For every infant-mother dyad data were collected on infant gender, type of delivery, gestational age at birth, birth weight, birth order, and mother'sreproductive history. Then mothers were given a diary to document the duration of crying/fussiness behav-iors of their infants for the next 12 wk. We scheduled home visits at the time the infants were 3 mo of age to collect the completed diaries and obtain additional information on infants' nutritional sources and identify if medications were used for colic relief. Cases of colic were identified by applying Wessel criteria to recordeddata. Chi-square and Mann-whitney U tests were usedto compare proportions for non-parametric and para-metric variables, respectively.RESULTS: From 413 infants, follow-up was completedfor 321 infants. In total, 65 infants (20.24%) satisfiedthe Wessel criteria for infantile colic. No statistical sig-nificance was found between colicky and non-colickyinfants according to gender, gestational age at birth,birth weight, type of delivery, and, infant's feedingpattern. However, firstborn infants had higher rate for developing colic (P = 0.03).CONCLUSION: Colic incidence was 20% in this popu-lation of Iranian infants. Except for birth order status,no other variable was significantly associated with in-fantile colic.

    Summary Objectives To determine risk factors for GBS colonisation in Gambian mothers and in their infants from birth to day 60–89 of age. Methods Swabs and breastmilk from mothers/infant pairs were collected and cultured on selective agar. Negative samples were analysed for GBS DNA via real-time PCR. Positive isolates were serotyped using multiplex PCR and gel-agarose electrophoresis. Results Seven hundred and fifty women/infant pairs were recruited. 253 women (33.7%) were GBS-colonised at delivery. The predominant serotypes were: V (55%), II (16%), III (10%), Ia (8%) and Ib (8%). 186 infants were colonised (24.8%) at birth, 181 (24.1%) at 6 days and 96 at day 60–89 (14%). Infants born before 34 weeks of gestation and to women with rectovaginal and breastmilk colonisation at delivery had increased odds of GBS colonisation at birth. Season of birth was associated with increased odds of persistent infant GBS colonisation (dry season vs. wet season AOR 2.9; 95% CI 1.6–5.2). Conclusion GBS colonisation is common in Gambian women at delivery and in their infants to day 60−89 and is dominated by serotype V. In addition to maternal colonisation, breastmilk and season of birth are important risk factors for infant GBS colonisation. PMID:26763186

    Parents' representations of their infants consist of parents' subjective experiences of how they perceive their infants. They provide important information about the quality of the parent-infant relationship and are closely related to parenting behavior and infant attachment. Previous studies have shown that parents' representations emerge during pregnancy. However, little is known about prenatal (risk) factors that are related to parents' representations. In a prospective study, 308 mothers and 243 fathers were followed during pregnancy and postpartum. Prenatal risk factors were assessed with an adapted version of the Dunedin Family Services Indicator (T.G. Egan et al., ; R.C. Muir et al., ). At 26 weeks' gestation and 6 months' postpartum, parents' representations of their children were assessed with the Working Model of the Child Interview (C.H. Zeanah, D. Benoit, L. Hirshberg, M.L. Barton, & C. Regan). Results showed stability between pre- and postnatal representations, with fathers having more disengaged representations than did mothers. In addition, prenatal risk factors of parenting problems were associated with the quality of parents' prenatal (only in mothers) and postnatal representations. This study provides valuable information concerning parents at risk of developing nonbalanced representations of their children. In clinical practice, these families could be monitored more intensively and may be supported in developing a more optimal parent-infant relationship. © 2015 Michigan Association for Infant Mental Health.

    Late-onset hyponatremia (LOH), hyponatremia occurring after two weeks of age with the achievement of full feeding, is the result of a negative sodium balance caused by inadequate salt intake or excessive salt loss due to immature renal or intestinal function in preterm infants. The aims of our study were to identify the risk factors for LOH and its influence on neonatal outcomes. This was a retrospective cohort analysis of 161 preterm infants born before 34 weeks of gestation between June 2009 and December 2010 at Seoul National University Hospital. LOH was defined as a sodium level ≤ 132 mEq/L or 133-135 mEq/L with oral sodium supplementation. LOH occurred in 49 (30.4%) of the studied infants. A lower gestational age, a shorter duration of parenteral nutrition, the presence of respiratory distress syndrome, the use of furosemide, and feeding with breast milk were significant risk factors for LOH. In terms of neonatal outcomes, the infants with LOH had longer hospital stays and higher risks of bronchopulmonary dysplasia and retinopathy of prematurity requiring surgery. LOH lasting at least 7 days significantly increased moderate to severe bronchopulmonary dysplasia, periventricular leukomalacia, and extra-uterine growth retardation. LOH is commonly observed in preterm infants; it may be a risk factor for bronchopulmonary dysplasia and retinopathy of prematurity or a marker of illness severity. PMID:25829814

    Full Text Available The risk factors for Sudden Infant Death Syndrome (SIDS parallel those associated with susceptibility to or severity of infectious diseases. There is no evidence that a single infectious agent is associated with SIDS; the common thread appears to be induction of inflammatory responses to infections. In this review, interactions between genetic and environmental risk factors for SIDS are assessed in relation to the hypothesis that many infant deaths result from dysregulation of inflammatory responses to minor infections. Risk factors are assessed in relation to three important stages of infection: 1 bacterial colonisation (frequency or density; 2 induction of temperature-dependent toxins; 3 induction or control of inflammatory responses.In this article we review the interactions among risk factors for SIDS for their effects on induction or control of inflammatory responses. The risk factors studied are genetic factors (sex, cytokine gene polymorphisms among ethnic groups at high or low risk of SID; developmental stage (changes in cortisol and testosterone levels associated with 2-4 month age range; environmental factors (virus infection, exposure to cigarette smoke. These interactions help to explain differences in the incidences of SIDS observed between ethnic groups prior to public health campaigns to reduce these infant deaths.

    Full Text Available We aim to determine risk factors and clinical outcomes for bowel perforation in premature infants with NEC. We analyzed clinical data of 57 cases of premature infants with NEC at our NICU between January 2010 and December 2012. Based on the presence of bowel perforation, we divided these infants into two groups: perforated NEC group (n=10 and nonperforated NEC group (n=47. We compared general information, clinical characteristics, and laboratory findings between groups. The perforated NEC group, compared to the nonperforated NEC group, had significantly lesser gestational age, lower birth weight, higher prevalence of apnea, mechanical ventilation, sepsis and shock, lower blood pH, higher levels of blood glucose, abnormal WBC count and thrombocytopenia, and elevated CRP (all P<0.05. Moreover, the perforated NEC group had significantly longer durations of fasting and TPN usage, higher incidences of EUGR and cholestasis, longer duration of antibiotics, higher frequency of advanced antibiotics use, and poorer prognosis than the nonperforated NEC group (all P<0.05. Bowel perforation in premature infants with NEC was associated with multiple risk factors. Early identification of some of these risk factors in premature infants with NEC may help implement early intervention to reduce the incidence of bowel perforation and thereby improve the prognosis.

All infants had chest X-ray at admission, and were treated due to RDS with nasal continuous positive airway pressure (CPAP, mechanical ventilation, or high frequency oscillatory ventilation. At admission we registered data regarding birth weight, gestational age, Apgar score, prenatally given steroids. Inclusion criteria were fulfilled by 417 infants. Data about timing, circumstances, side and treatment of pneumothorax were gathered from medical records.Results: Mean birth weight was 1,477 g, mean gestational age 29.6 weeks. We report 98 infants who did not survive. We also report incidence of pneumothorax in 5% of the infants with RDS. In this study pneumothorax and non-pneumothorax groups didn’t differ regarding sex, gestational age (median 29 and 30 nor birth weight (p = 0.818. Apgar score at the 1st and 5th minute of life had no influence in genesis of pulmonary air leak, neither prenatally given steroids (p = 0.639, nor surfactant administration. There was a low coverage of preterm infants with prenatal steroids (overall 28.29%. We found that FiO2 ≥ 0.4 in the first 12 hours of life, and need for mechanical ventilation are predicting factors for developing pneumothorax (p < 0.05.Conclusion: Together with mechanical ventilation, inspired fraction of oxygen higher than 40%, needed to provide adequate oxygenation in the first 12 hours of life in preterm infants, could be a predictive factor in selecting the highest risk babies for development of

    Congenital diaphragmatic hernia (CDH) is a rare congenital anomaly and remains among the most challenging ICU-managed disease. Beside severe pulmonary hypertension, lung hypoplasia and major abdominal surgery, infective complications remain major determinants of outcome. However, the specific incidence of sepsis as well as associated risk factors is unknown. This prospective, 4-year observational study took place in the pediatric intensive care and neonatal medicine department of the Paris South University Hospitals (Le Kremlin-Bicêtre, France), CDH national referral center and involved 62 neonates with CDH. During their ICU stay, 28 patients (45%) developed 38 sepsis episodes. Ventilator-associated pneumonia (VAP: 23/38; 31.9 VAP per 1000 days of mechanical ventilation) and central line-associated blood stream infections (CLABSI: 5/38; 5.5 per 1000 line days) were the most frequently encountered infections. Multivariate analysis showed that gestational age at birth and intra-thoracic position of liver were significantly associated with the occurrence of sepsis. Infected patients had longer duration of mechanical and noninvasive ventilation (16.2 and 5.8 days, respectively), longer delay to first feeding (1.2 days) and a longer length of stay in ICU (23 days), but there was no difference in mortality. Healthcare-associated infections, and more specifically VAP, are the main infective threat in children with CDH. Sepsis has a significant impact on the duration of ventilator support and ICU length of stay but does not impact mortality. Low gestational age and intra-thoracic localization of the liver are two independent risk factors associated with sepsis.

    Accelerated infant growth is associated with an altered, mostly adverse adult cardiometabolic risk profile. The importance of genetic and environmental factors to these associations is unclear. The objective was to examine the importance of genetic and environmental factors in the associations between infant growth and adult cardiometabolic risk factors (anthropometric characteristics, lipids, insulin sensitivity, leptin, blood pressure, and fibrinogen) in twins. Cardiometabolic risk factors were assessed in 240 twin pairs (aged 18-34 y) from the East Flanders Prospective Twin Survey. Infant growth was defined as change in weight z score. We regressed intrapair differences in growth during 4 growth windows (0-1, 1-6, 6-12, and 12-24 mo) against intrapair differences in the risk factors in monozygotic and dizygotic twins separately. Within monozygotic twin pairs only, associations between infant growth and most adult lipids, glucose, leptin, and blood pressure (eg, systolic blood pressure: b = 5.95 mm Hg per change in z score, P = 0.01 in monozygotic twins; b = -1.64, P = 0.82 in dizygotic twins from 12 to 24 mo) were found. Within dizygotic twin pairs only, associations between growth and triglycerides and fibrinogen (eg, fibrinogen: b = 0.07 ln mg/dL per change in z score, P = 0.31 in monozygotic twins; b = 0.79, P = 0.01 in dizygotic twins from 0 to 1 mo) were identified. Most associations showed a detrimental effect of accelerated growth, but beneficial associations were also identified (eg, total-to-high-density-lipoprotein cholesterol ratio: b = -0.22 per change in z score from 1 to 6 mo, P = 0.008 in monozygotic twins). Our data showed that environmental factors play a role in the associations between infant growth and most adult lipids, glucose, leptin, and blood pressure, whereas genetic factors are involved regarding triglycerides and fibrinogen.

Materials and methods: A total of 3,120 infants (aged 3 months who underwent hearing screening using a universal hearing screening program using automated otoacoustic emission test between November 1, 2010 and May 31, 2012 in Uttaradit Hospital, Buddhachinaraj Hospital, and Sawanpracharuk Hospital (tertiary hospitals located in Northern Thailand were included in this prospective cohort study. Results: Of the 3,120 infants, 135 (4.3% were confirmed to have hearing loss with the conventional otoacoustic emission test. Five of these 135 infants (3.7% with hearing loss showed test results consistent with auditory brainstem responses. From the univariable analysis, there were eleven potential risk factors associated with hearing deterioration. On multivariable analysis, the risk factors independently associated with hearing loss at 3 months were birth weight 1,500–2,500 g (risk ratio [RR] 1.6, 95% confidence interval [CI] 1.1–2.6, APGAR score <6 at 5 minutes (RR 2.2, 95% CI 1.1–4.4, craniofacial anomalies (RR 2.5, 95% CI 1.6–4.2, sepsis (RR 1.8, 95% CI 1.0–3.2, and ototoxic exposure (RR 4.1, 95% CI 1.9–8.6. Conclusion: This study concluded that low birth weight, APGAR score <6 at 5 minutes, craniofacial anomalies, sepsis, and ototoxic exposure are the risk factors for bilateral hearing loss in infants (aged 3 months and proper tests should be performed to identify these risk factors. As an outcome, under the present circumstances, it is suggested that infirmary/physicians/general practitioners/health action centers/polyclinics should carry out universal hearing screening in all

    HIV-exposed infants, including those who do not become infected, have higher morbidity and mortality rates than HIV unexposed infants. The underlying mechanisms of this difference are largely unknown. The objective of this study was to identify the risk factors for mortality among HIV-exposed (infected as well as uninfected) infants in a prevention of mother-to-child transmission (PMTCT) programme in Cameroon. We analysed the data from 319 mother-infant pairs included in a PMTCT programme at a rural and an urban hospital between 2004 and 2012. The programme offered free formula feeding, monthly follow-up visits and antiretroviral therapy (ART) according to national PMTCT guidelines. Mother-infant pairs were divided in three study groups, based on year of recruitment and study site: (I) rural hospital, 2004-07; (II) rural hospital, 2008-12; (III) urban hospital, 2008-12. Two hundred and eighty-five medical records were included in the final analysis. Infant mortality rates were 23.9%, 20.0% and 5.3% in group I, II and III, respectively (P = 0.02). Hazard ratios of infant mortality were 6.4 (P < 0.001) for prematurity, 4.6 (P = 0.04) for no maternal use of ARTs, 5.6 (P = 0.025) for mixed feeding, 2.7 for home deliveries (P = 0.087) and 0.4 (P = 0.138) for urban study group. In this programme, prematurity, no ART use, and the practice of mixed feeding were independent predictors of infant mortality. Mixed feeding and not using ART increased the hazard of death, probably through its increased risk of HIV infection. Although mortality rates were significantly higher in the rural area, rural setting was not a risk factor for infant mortality. These findings may contribute to the development of tailor-made programmes to reduce infant mortality rates among HIV-exposed infants. © 2014 John Wiley & Sons Ltd.

  14. Indoor Residential Chemical Exposures as Risk Factors for Asthmaand Allergy in Infants and Children: a Review

    Mendell, M.J.

    2006-03-01

    Most research into effects of residential indoor air exposures on asthma and allergies has focused on exposures to biologic allergens, moisture and mold, endotoxin, or combustion byproducts. This paper briefly reviews reported findings on associations of asthma or allergy in infants or children with risk factors related to indoor chemical emissions from residential materials or surface coatings. Associations, some strong (e.g., odds ratios up to 13), were reported. The most frequently identified risk factors were formaldehyde, aromatic organic compounds such as toluene and benzene, plastic materials and plasticizers, and recent painting. Exposures and consequent effects from indoor sources may be exacerbated by decreased ventilation. Identified risk factors may be proxies for correlated exposures. Findings suggest the frequent occurrence of important but preventable effects on asthma and allergy in infants and children worldwide from modern residential building materials and coatings.

    Hospitalized bronchiolitis imposes a significant burden among infants, particularly among Indigenous children. Traditional or known risk factors for severe disease are well described, but there are limited data on risks for prolonged hospitalization and persistent symptoms. Our aims were to determine factors (clinical and microbiological) associated with (i) prolonged length of stay (LOS); (ii) persistent respiratory symptoms at 3 weeks; (iii) bronchiectasis up to ∼24 months post-hospitalisation; and (iv) risk of respiratory readmissions within 6 months. Indigenous infants hospitalized with bronchiolitis were enrolled at Royal Darwin Hospital between 2008 and 2013. Standardized forms were used to record clinical data. A nasopharyngeal swab was collected at enrolment to identify respiratory viruses and bacteria. The median age of 232 infants was 5 months (interquartile range 3-9); 65% male. On multivariate regression, our 12 point severity score (including accessory muscle use) was the only factor associated with prolonged LOS but the effect was modest (+3.0 hr per point, 95%CI: 0.7, 5.1, P = 0.01). Presence of cough at 3 weeks increased the odds of bronchiectasis (OR 3.0, 95%CI: 1.1, 7.0, P = 0.03). Factors associated with respiratory readmissions were: previous respiratory hospitalization (OR 2.3, 95%CI: 1.0, 5.4, P = 0.05) and household smoke (OR 2.6, 95%CI: 1.0, 6.3, P = 0.04). Increased severity score is associated with prolonged LOS in Indigenous children hospitalized with bronchiolitis. As persistent symptoms at 3 weeks post-hospitalization are associated with future diagnosis of bronchiectasis, optimising clinical care beyond hospitalization is needed to improve long-term respiratory outcomes for infants at risk of respiratory disease.

    Full Text Available OBJECTIVE: To analyze the correlation of risk factors to the occurrence of urinary tract infection in full-term newborn infants. PATIENTS AND METHODS: Retrospective study (1997 including full-term infants having a positive urine culture by bag specimen. Urine collection was based on: fever, weight loss > 10% of birth weight, nonspecific symptoms (feeding intolerance, failure to thrive, hypoactivity, debilitate suction, irritability, or renal and urinary tract malformations. In these cases, another urine culture by suprapubic bladder aspiration was collected to confirm the diagnosis. To compare and validate the risk factors in each group, the selected cases were divided into two groups: Group I - positive urine culture by bag specimen collection and negative urine culture by suprapubic aspiration, and Group II - positive urine culture by bag specimen collection and positive urine culture by suprapubic aspiration . RESULTS: Sixty one infants were studied, Group I, n = 42 (68.9% and Group II, n = 19 (31.1%. The selected risk factors (associated infectious diseases, use of broad-spectrum antibiotics, renal and urinary tract malformations, mechanical ventilation, parenteral nutrition and intravascular catheter were more frequent in Group II (p<0.05. Through relative risk analysis, risk factors were, in decreasing importance: parenteral nutrition, intravascular catheter, associated infectious diseases, use of broad-spectrum antibiotics, mechanical ventilation, and renal and urinary tract malformations. CONCLUSION: The results showed that parenteral nutrition, intravascular catheter, and associated infectious diseases contributed to increase the frequency of neonatal urinary tract infection, and in the presence of more than one risk factor, the occurrence of urinary tract infection rose up to 11 times.

Material & Methods: In a retrospective case control clinical study files of all premature infants with birth weights less than 1500 grams admitted between April 2004 and Oct 2005 to the neonatal intensive care unit of Akbar Abadi hospital in Tehran were reviewed. 39 infants with IVH grade 3 and 4 were identified. A control group of 82 VLBW infants matched for gestational age and birth weight were selected. Prenatal data, delivery characteristics, neonatal course data and reports of cranial ultrasonography were carefully collected for both groups. Those variables that achieved significance (p<0.05 in univariate analysis entered to multivariate logistic regression analysis. Findings: A total of 325 VLBW infants were evaluated. Mortality rate was 21.5%. Of the remaining the incidence of high grade IVH was 15.5%. Multivariate logistic analysis showed that following factors are associated with greater risk of high grade IVH occurrence: Low gestational age (OR: 3.72; 95% CI: 1.65-8.38, low birth weight (OR: 3.42; 95% CI: 1.65-8.38, low Apgar score at 5 minute (OR:1.58; 95% CI:1.59-6.32, hyaline membrane disease (HMD, OR: 3.16; 95% CI: 1.42-7.45 and maternal tocolytic therapy with magnesium sulfate (OR: 4.40; 95% CI: 1.10-24.5. Conclusion: Our results showed that maternal tocolytic therapy, mechanical ventilation, low gestational age, low birth weight, apnea, and low 5 minute Apgar score increased the risk of major IVH.

    This study evaluated sepsis as a risk factor for neonatal morbidities and investigated the association between specific pathogens and neonatal morbidities. This was a nationwide Swedish prospective cohort study, consisting of the 497 extremely premature children, who were born before 27 weeks of gestation between 2004 and 2007 and survived their first year of life. Neonatal sepsis was evaluated as a risk factor for neonatal morbidity using multiple logistic linear regression analyses. We found that 326 (66%) of the infants had at least one sepsis episode and coagulase-negative staphylococci was the most common pathogen. Definite sepsis, with an odds ratio (OR) of 1.6, was associated with severe bronchopulmonary dysplasia, but not clinical sepsis (OR 1.1). Definite sepsis was also associated with a prolonged hospital stay (OR 1.6). Sepsis was not significantly associated with a higher risk of retinopathy of prematurity or intraventricular haemorrhage. Extremely preterm infants face a great risk of acquiring neonatal sepsis, with coagulase-negative staphylococci being the most common pathogen in this population. Definite sepsis seemed to be a risk factor for severe bronchopulmonary dysplasia and prolonged hospital stay, but the associations were weaker than in previous studies. ©2015 Foundation Acta Paediatrica.

    This article describes how a community coalition focusing on maternal and child health engages community participation through the use of geographic information systems (GIS) mapping, developing strategies that culminate in the implementation of a service delivery plan to improve birth outcomes. Vital statistics data from 2007 to 2009 was analyzed by zip code in Pinellas County Florida to produce choropleth thematic maps using ArcGIS for 3 year rolling average infant deaths and single year percentages for prematurity. The maps were presented at the organization's annual coalition meeting to discuss risk areas, changes over time in the selected indicators and solicit community feedback on how to best target issues addressing infant mortality and prematurity. The maps identified new zip codes of concern for prematurity in addition to known high risk zip codes for both infant mortality and prematurity. The community identified changes in demographic composition and changes in housing patterns, such as new mobile home areas, in the high risk areas. In response, the community assisted the Coalition in developing a holistic plan addressing risk factors affecting birth outcomes by expanding current services, hiring a nutritionist, and contracting a health navigator. When compared to tables and charts, a visual depiction of a neighborhood by recognizable zip codes is a useful tool to help community decision makers better visualize public health concerns and interpret trends based on local knowledge. Public health professionals should use this community knowledge to interpret research results and implement strategies to improve birth outcomes.

    We assessed risk factors for urinary tract infection in children with prenatal hydronephrosis We identified 376 infants with prenatal hydronephrosis in an institutional database. The occurrence of febrile urinary tract infection in the first 2 years of life was ascertained by chart review. Febrile urinary tract infection was defined as a positive culture from a catheterized urine specimen in a patient with a fever of 38.0C or greater. Multivariate logistic regression was used to assess gender, circumcision status, hydronephrosis grade, vesicoureteral reflux grade and antibiotic prophylaxis as predictors of the risk of urinary tract infection. Included in analysis were 277 males and 99 females. Hydronephrosis was high grade in 128 infants (34.0%) and vesicoureteral reflux was present in 79 (21.0%). Antibiotic prophylaxis was prescribed in 60.4% of patients, preferentially to females vs males (70.7% vs 56.7%), those with high vs low grade hydronephrosis (70.3% vs 55.2%) and those with vs without vesicoureteral reflux (96.2% vs 50.8%). On multivariate analysis there was an association between high grade hydronephrosis and an increased risk of urinary tract infection (adjusted OR 2.40, 95% CI 1.26-4.56). Females (adjusted OR 3.16, 95% CI 0.98-10.19) and uncircumcised males (adjusted OR 3.63, 95% CI 1.18-11.22) were also at higher risk than circumcised males. Antibiotic prophylaxis was not associated with a decreased risk of urinary tract infection (adjusted OR 0.93, 95% CI 0.45-1.94). High grade hydronephrosis, female gender and uncircumcised status in males are independent risk factors for febrile urinary tract infection in infants with prenatal hydronephrosis. Antibiotic prophylaxis did not reduce the risk of urinary tract infection in the study group. Copyright © 2014 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Mother HBV DNA or HBeAg positivity,neonate HBeAg positivity,mode of delivery, threatened abortion and threatened premature abor were processed with meta analysis.Criteria for selection of published studies for meta analysis were based on principle by Abdolmaleky HM[1].Odds ratio (OR) was calculated and summarized by fixed effect model or random-effects model using RevMan software. The heterogeneity of the group of Ors was assessed using an x2 test. The significance of he pooled OR was determined by the u-test. The strength of association was assessed using the OR.An OR>1. 0 indicated a positive association between the risk factor and neonate HBV infection. Results:After meta analysis of factors concerned, a significant association was found between the positivity of HBeAg in mother and neonate, of HBV DNA in other peripheral serum, and HBV mother-to-infant transmission, with a pooled OR equal to 19.43 (95% CI=8.77-43.06), 36.5 (95% CI=19.85-67.11),and 36.5 (95 % CI= 19.85-67.11) respectively. Mode of delivery, threatened abortion and threatened premature labor proved not to be of risk factors on the mother-to-infant transmission of HBV. Conclusion:Mother HBV DNA or HBeAg positivity and neonate HBeAg positivity were proved to be of risk factors affecting the transmission of HBV from mother to fetal.

    In Canada, sudden infant death syndrome (SIDS) remains the leading cause of postneonatal death. However, SIDS rates have been declining in many countries, including Canada. This decline has been largely attributed to recommendations to avoid placing infants to sleep in the prone position. We examined the postneonatal rate of mortality due to SIDS and to other causes in relation to the initial risk reduction campaign. The postneonatal mortality rate due to SIDS decreased from 0.97 to 0.54 per 1,000 neonatal survivors between 1985-1989 and 1994-1998 (relative risk [RR] = 0.56, 95% confidence interval [CI] 0.51-0.62). The rate of postneonatal mortality due to other causes also decreased during the same period, though to a smaller extent, from 1.19 to 0.86 (RR = 0.72, 95% CI 0.66-0.78). With the exception of seasonality, established risk factors for SIDS remained essentially unchanged between the two time periods. The observed reduction in postneonatal SIDS is consistent with a positive impact of the initial recommendations regarding risk reduction. However, the lack of reliable risk factor data limits the extent to which the decline can be attributed directly to the campaign.

    Low birth weight (LBW) and fetal anaemia (FA) are common in malaria endemic areas. To investigate the incidence of infectious morbidity in infants in rural Malawi in relation to birth weight and fetal anaemia, a cohort of babies was followed for a year on the basis of LBW (<2500) and FA (cord haemoglobin < 12.5 g/dl). A matched group of normal birth weight (NBW), non-anaemic (NFA) new-borns were enrolled as controls. Morbidity episodes were recorded at 4-weekly intervals and at each extra visit made to a health centre with any illness. Infants in the NBW NFA group experienced an average of 1.15 (95% C.I. 0.99, 1.31), 1.04 (0.89, 1.19), 0.92 (0.73, 1.11) episodes per year of malaria, respiratory infection and diarrhoea respectively. Corresponding values for the LBW FA group were 0.83 (0.5, 1.16), 0.82 (0.5, 1.16) and 0.76 (0.33, 1.19). FA was not associated with a higher incidence of morbidity, but was significantly associated with a shorter time to first illness episode (p = 0.014). LBW was not a significant risk factor for higher morbidity incidence. LBW and FA were not significant risk factors for incidence of illness episodes in infants.

    ABSTRACT OBJECTIVE To evaluate the association between recurrent wheezing and atopy, the Asthma Predictive Index, exposure to risk factors, and total serum IgE levels as potential factors to predict recurrent wheezing. METHODS A case-control study with infants aged 6-24 months treated at a specialized outpatient clinic from November 2011 to March 2013. Evaluations included sensitivity to inhalant and food antigens, positive Asthma Predictive Index, and other risk factors for recurrent wheezing (smoking during pregnancy, presence of indoor smoke, viral infections, and total serum IgE levels). RESULTS We evaluated 113 children: 65 infants with recurrent wheezing (63.0% male) with a mean age of 14.8 (SD = 5.2) months and 48 healthy infants (44.0% male) with a mean age of 15.2 (SD = 5.1) months. In the multiple analysis model, antigen sensitivity (OR = 12.45; 95%CI 1.28–19.11), positive Asthma Predictive Index (OR = 5.57; 95%CI 2.23–7.96), and exposure to environmental smoke (OR = 2.63; 95%CI 1.09–6.30) remained as risk factors for wheezing. Eosinophilia ≥ 4.0% e total IgE ≥ 100 UI/mL were more prevalent in the wheezing group, but failed to remain in the model. Smoking during pregnancy was identified in a small number of mothers, and secondhand smoke at home was higher in the control group. CONCLUSIONS Presence of atopy, positive Asthma Predictive Index and exposure to environmental smoke are associated to recurrent wheezing. Identifying these factors enables the adoption of preventive measures, especially for children susceptible to persistent wheezing and future asthma onset. PMID:27143615

    Full Text Available BACKGROUND: Tobacco smoking is a major cause of morbidity and mortality, including during pregnancy. Although effective ways of promoting smoking cessation during pregnancy exist, the impact of these interventions has not been studied at a national level. We estimated the prevalence of smoking throughout pregnancy in the Netherlands and quantified associations of maternal smoking throughout pregnancy with socioeconomic, behavioural, and neonatal risk factors for infant health and development. METHODOLOGY/PRINCIPAL FINDINGS: Data of five national surveys, containing records of 14,553 Dutch mothers and their offspring were analyzed. From 2001 to 2007, the overall rate of smoking throughout pregnancy fell by 42% (from 13.2% to 7.6% mainly as a result of a decrease among highly educated women. In the lowest-educated group, the overall rate of smoking throughout pregnancy was six times as high as in the highest-educated group (18.7% versus 3.2%. Prenatal tobacco smoke exposure was associated with increased risk of extremely preterm (infants (OR 3.08; 95% CI 2.66 to 3.57. Smoking-attributable risk percent in the population (based on adjusted risk ratios were estimated at 29% for extremely preterm births and at 17% for SGA outcomes. Infants of smokers were more likely to experience significant alcohol exposure in utero (OR 2.08; 95%CI 1.25 to 3.45 and formula feeding in early life (OR 1.91; 95% CI 1.69 to 2.16. CONCLUSIONS: The rates of maternal smoking throughout pregnancy decreased significantly in the Netherlands from 2001 to 2007. If pregnant women were to cease tobacco use completely, an estimated 29% of extremely preterm births and 17% of SGA infants may be avoided annually.

    Full Text Available Data were prospectively obtained from exclusively breast-fed healthy term neonates at birth and from healthy mothers with no obstetric complication to determine risk factors for excess weight loss and hypernatremia in exclusively breast-fed infants. Thirty-four neonates with a weight loss > or = 10% were diagnosed between April 2001 and January 2005. Six of 18 infants who were eligible for the study had hypernatremia. Breast conditions associated with breast-feeding difficulties (P < 0.05, primiparity (P < 0.005, less than four stools (P < 0.001, pink diaper (P < 0.001, delay at initiation of first breast giving (P < 0.01, birth by cesarean section (P < 0.05, extra heater usage (P < 0.005, extra heater usage among mothers who had appropriate conditions associated with breast-feeding (P < 0.001, mean weight loss in neonates with pink diaper (P < 0.05, mean uric acid concentration in neonates with pink diaper (P < 0.0001, fever in hypernatremic neonates (P < 0.02, and the correlation of weight loss with both serum sodium and uric acid concentrations (P < 0.02 were determined. Excessive weight loss occurs in exclusively breast-fed infants and can be complicated by hypernatremia and other morbidities. Prompt initiation of breast-feeding after delivery and prompt intervention if problems occur with breast-feeding, in particular poor breast attachment, breast engorgement, delayed breast milk "coming in", and nipple problems will help promote successful breast-feeding. Careful follow-up of breast-feeding dyads after discharge from hospital, especially regarding infant weight, is important to help detect inadequate breast-feeding. Environmental factors such as heaters may exacerbate infant dehydration.

    Assessment of the joint and independent relationships of gestational weight gain and prepregnancy body mass index (BMI) on risk of infant mortality was performed. This study used Pennsylvania linked birth-infant death records (2003-2011) from infants without anomalies born to mothers with prepregnancy BMI categorized as underweight (n = 58,973), normal weight (n = 610,118), overweight (n = 296,630), grade 1 obesity (n = 147,608), grade 2 obesity (n = 71,740), and grade 3 obesity (n = 47,277). Multivariable logistic regression models stratified by BMI category were used to estimate dose-response associations between z scores of gestational weight gain and infant death after confounder adjustment. Infant mortality risk was lowest among normal-weight women and increased with rising BMI category. For all BMI groups except for grade 3 obesity, there were U-shaped associations between gestational weight gain and risk of infant death. Weight loss and very low weight gain among women with grades 1 and 2 obesity were associated with high risks of infant mortality. However, even when gestational weight gain in women with obesity was optimized, the predicted risk of infant death remained higher than that of normal-weight women. Interventions aimed at substantially reducing preconception weight among women with obesity and avoiding very low or very high gestational weight gain may reduce risk of infant death. © 2015 The Obesity Society.

    Celiac disease (CD) is an immune-mediated enteropathy involving genetic and environmental factors whose interaction might influence disease risk. The aim of this study was to determine the effects of milk-feeding practices and the HLA-DQ genotype on intestinal colonization of Bacteroides species in infants at risk of CD development. This study included 75 full-term newborns with at least one first-degree relative suffering from CD. Infants were classified according to milk-feeding practice (breast-feeding or formula feeding) and HLA-DQ genotype (high or low genetic risk). Stools were analyzed at 7 days, 1 month, and 4 months by PCR and denaturing gradient gel electrophoresis (DGGE). The Bacteroides species diversity index was higher in formula-fed infants than in breast-fed infants. Breast-fed infants showed a higher prevalence of Bacteroides uniformis at 1 and 4 months of age, while formula-fed infants had a higher prevalence of B. intestinalis at all sampling times, of B. caccae at 7 days and 4 months, and of B. plebeius at 4 months. Infants with high genetic risk showed a higher prevalence of B. vulgatus, while those with low genetic risk showed a higher prevalence of B. ovatus, B. plebeius, and B. uniformis. Among breast-fed infants, the prevalence of B. uniformis was higher in those with low genetic risk than in those with high genetic risk. Among formula-fed infants, the prevalence of B. ovatus and B. plebeius was increased in those with low genetic risk, while the prevalence of B. vulgatus was higher in those with high genetic risk. The results indicate that both the type of milk feeding and the HLA-DQ genotype influence the colonization process of Bacteroides species, and possibly the disease risk. PMID:21642397

    Factors operating in the first year of life are critical in determining the onset and persistence of wheezing in preschool children. This study was designed to examine the prevalence and risk factors of wheeze in the first year of life in Dutch infants. This was a population-based survey of 13-month-old infants visiting well baby clinics for a scheduled immunization. Parents/caregivers completed a standardized validated questionnaire on respiratory symptoms in the first year of life and putative risk factors. The independent influence of these factors for wheeze was assessed by multiple logistic regression analysis. A total of 1,115 questionnaires were completed. Wheeze ever (with a prevalence in the first year of life of 28.5%) was independently associated with male gender, eczema, sibs with asthma, any allergic disease in the family, day care, damp housing, and asphyxia. Recurrent wheeze (prevalence 14.5%) showed independent associations with eczema, sibs with asthma, and day care. In addition to these factors, severe wheeze (prevalence 15.4%) was also associated with premature rupture of membranes during birth, and with damp housing. Wheeze is common during the first year of life, and places a major burden on families and the health care system. Factors associated with wheeze are mainly related to markers of atopic susceptibility, and to exposure to infections. The strongest modifiable risk factor for wheeze in the first year of life is home dampness. Interventions to reduce home dampness to reduce wheeze in infancy should be examined.

    Full Text Available Introduction  Sudden Infant Death Syndrome (SIDS is a disease which causes unexpected death of infants aged less than 1 year. Given the undeniable role of parents in the presence or absence of SIDS risk factors, the present study aimed to studythe prevalence and the relationship between characteristics and conditions of parent’s infants with SIDS risk factors. Materials and Methods  In this cross-sectional descriptive-analytic study, 1,021 infants aged 1 to 12 months in the health centers in Qom-Iran in 2014 were selected as the sample by stratified random sampling method. The required data were collected using an author-made questionnaire on SIDS risk factors. The obtained data were analyzed by descriptive and inferential statistics in SPSS 18 at a significance level of 95%. Results 4.5% of mothers were younger than 20 years, 92.3% infants had a co-sleeping with their parents, and 35.7% of infants had a bed-sharing with their parents. 19% of infants used Soft pillow. Study findings showed that there is no significant relationship between the age of mothers and using a shared bedroom (P>0.05, while such a relationship exists between education backgrounds of parents and sharing a bedroom (P

    There are significant delays in implementing vaccination among preterm infants. Description of the frequency and kinds of adverse events following immunization in preterms. Establishment of the group of preterms who will distinctively be susceptible to adverse events. Demographical, clinical data and the occurrence of adverse events after DTaP, HIB and pneumococcal vaccination among preterms during their initial hospitalization were prospectively collected with the use of an electronic data form between 1st June 2011 and 31st May 2015. The analysis was conducted on 138 patients. The groups were divided according to maturity (I: ≤ GA 28w n=73 and GA 29-36 w n=65). There were no statistically significant differences between the groups in the occurrence of adverse events. Out of the total group, following vaccination apnoea developed in 6 newborns (4%) and activity dysfunctions were observed in 13 newborns (10%). The occurrence of apnoea after vaccination positively correlated with the time of non-invasive ventilation and the occurrence of late infection. There were no statistically significant demographical or clinical risk factors for the development of activity dysfunctions following vaccination. Term vaccination in clinically stable preterm infants is a safe medical procedure. However, long-term non-invasive respiratory support and late infections are risk factors for apnea following vaccinations. In these patients vaccinations should be considered during hospitalization.

    To investigate the risk factors for recurrent wheezing in infants and young children suffering from dust mite allergy after their first wheezing. A total of 1 236 infants and young children who experienced a first wheezing episode and were hospitalized between August 2014 and February 2015 were enrolled, among whom 387 were allergic to dust mites. These infants and young children were followed up to 1 year after discharge. A total of 67 infants and young children who experienced 3 or more recurrent wheezing episodes within 1 year were enrolled as the recurrent wheezing group, while 84 infants and young children who did not experience recurrent wheezing during follow-up were enrolled as the control group. Univariate analysis and multivariate logistic stepwise regression analysis were performed to investigate the risk factors for recurrent wheezing in these patients. The univariate analysis showed that the age on admission, wheezing time before admission, Mycoplasma pneumoniae infection rate, and influenza virus infection rate were associated with recurrent wheezing. The multivariate logistic stepwise regression analysis showed that the older age on admission (OR=2.21, P=0.04) and Mycoplasma pneumoniae infection (OR=3.54, P=0.001) were independent risk factors for recurrent wheezing. Infants and young children who are allergic to dust mites, especially young children, have a significantly increased risk of recurrent wheezing if they are complicated by Mycoplasma pneumoniae infection during the first wheezing episode.

    Neonatal dysphagia, or abnormalities of swallowing, represent a major global problem, and consequences of dysfunctional feeding patterns carry over into infancy and toddler age groups. Growth, development, and independent feeding skills are all delayed among high-risk infants. Such a group comprises premature birth, low-birth-weight, congenital anomalies, perinatal asphyxia, postsurgical, and sepsis categories. The conflict between pathophysiologic and pragmatic feeding strategies remains a major conundrum and is largely due to a lack of validated diagnostic approaches amid heterogeneity of the patient phenotype. Thus, well-tested feeding management strategies that can be generalizable are lacking. Furthermore, the aerodigestive symptoms and signs, potential risk factors, and contributory etiologies remain nonspecific. This article presents mechanistic evidence related to the pathophysiologic basis of neonatal dysphagia as well as potential opportunities to improve feeding abilities and long-term development.

    Full Text Available Environmental exposures that occur in utero and during early life may contribute to the development of childhood asthma through alteration of the human microbiome. The objectives of this study were to estimate the cumulative effect and relative importance of environmental exposures on the risk of childhood asthma.We conducted a population-based birth cohort study of mother-child dyads who were born between 1995 and 2003 and were continuously enrolled in the PRIMA (Prevention of RSV: Impact on Morbidity and Asthma cohort. The individual and cumulative impact of maternal urinary tract infections (UTI during pregnancy, maternal colonization with group B streptococcus (GBS, mode of delivery, infant antibiotic use, and older siblings at home, on the risk of childhood asthma were estimated using logistic regression. Dose-response effect on childhood asthma risk was assessed for continuous risk factors: number of maternal UTIs during pregnancy, courses of infant antibiotics, and number of older siblings at home. We further assessed and compared the relative importance of these exposures on the asthma risk. In a subgroup of children for whom maternal antibiotic use during pregnancy information was available, the effect of maternal antibiotic use on the risk of childhood asthma was estimated.Among 136,098 singleton birth infants, 13.29% developed asthma. In both univariate and adjusted analyses, maternal UTI during pregnancy (odds ratio [OR] 1.2, 95% confidence interval [CI] 1.18, 1.25; adjusted OR [AOR] 1.04, 95%CI 1.02, 1.07 for every additional UTI and infant antibiotic use (OR 1.21, 95%CI 1.20, 1.22; AOR 1.16, 95%CI 1.15, 1.17 for every additional course were associated with an increased risk of childhood asthma, while having older siblings at home (OR 0.92, 95%CI 0.91, 0.93; AOR 0.85, 95%CI 0.84, 0.87 for each additional sibling was associated with a decreased risk of childhood asthma, in a dose-dependent manner.

    A population based case control study was conducted to examine alcohol consumption and maternal smoking during pregnancy and the risk of SIDS in an Irish population. Each SIDS case (n = 287) was compared with control infants (n = 832) matched for date and place of birth for infants born from 1994 to 2001. Conditional logistic regression was used to investigate differences between Cases and Controls establishing Odds Ratio\\'s (OR) and 95% Confidence Intervals (CI). Mothers who smoked were 3 times more likely to have a SIDS Case, and a dose response effect was apparent, with mothers smoking 1-10 cigarettes\\/day OR 2.93 (CI 1.50-5.71), and those smoking > 10 cigarettes\\/day OR 4.36 (CI 2.50-7.61). More Case mothers consumed alcohol during pregnancy than Control mothers and, within drinkers, the amount of alcohol consumed was also greater (p < 0.05). A dose response with frequency of drinking was apparent. The adjusted odds ratio for those consuming alcohol in all three trimesters was 3.59 (CI:1.40-9.20). Both of these risk factors are modifiable and need to be incorporated into antenatal education from a SIDS point of view.

    Subclinical mastitis, as diagnosed by an elevated sodium/potassium ratio in milk accompanied by an increased milk concentration of the inflammatory cytokine, interleukin-8 (IL8), was found to be common among breast feeding women in Bangladesh and Tanzania. Subclinical mastitis results in leakage of plasma constituents into milk, active recruitment of leukocytes into milk, and possible infant gut damage from inflammatory cytokines. Therefore, we wished to investigate whether subclinical mastitis was related to known risk factors for postnatal mother-to-child HIV transmission, that is, high milk viral load or increased infant gut permeability. HIV-infected South African women were recruited at the antenatal clinic of McCord's Hospital, Durban. Risks and benefits of different feeding strategies were explained to them and, if they chose to breast feed, they were encouraged to do so exclusively. Women and infants returned to the clinic at 1, 6 and 14 weeks postpartum for an interview about infant health and current feeding pattern, a lactulose/mannitol test of infant gut permeability, and milk sample collection from each breast separately for analysis of Na/K ratio, IL8 concentration and viral load in the cell-free aqueous phase. Only preliminary cross-sectional analyses from an incomplete database are available at this point. Moderately (0.6-1.0) or greatly (>1.0) raised Na/K ratio was common and was often unilateral, although as a group right and left breasts did not differ. Considering both breasts together, normal, moderately raised or greatly raised Na/K was found, respectively, in 51%, 28%, 21% of milk samples at 1 week (n=190); 69%, 20%, 11% at 6 weeks (n=167); and 72%, 16%, 12% at 14 weeks (n=122). IL8 concentration significantly correlated with both Na/K and viral load at all times. Na/K correlated with viral load at 1 and 14, but not 6 weeks. At 1 and 14 weeks, geometric mean viral loads in samples with Na/K > 1.0 were approximately 4 times those in samples

    Full Text Available Background One of the serious challenges facing neonatal medicine is meconium aspiration syndrome, delays in the treatment of which can lead to high mortality. Objectives This study was designed and conducted with the aim of determining the mortality rate and risk factors affecting this rate in newborn infants with meconium aspiration syndrome. Methods This study was conducted as a retrospective descriptive research on newborn infants with meconium aspiration syndrome hospitalized at the neonatal intensive care unit (NICU of Fatemieh and Be’sat hospitals in Hamadan city during a 10-year period from 2004 to 2014. Demographic information of the mother and the newborn, hospitalization course, the need for mechanical ventilation, and complications and outcomes of disease were extracted and were analyzed using the SPSS software version 22. Results Sixty-three newborn infants, diagnosed with meconium aspiration syndrome, were entered in this study, 40% of them were male, 85.7% wighed more than 2500 g, and 17.5% were post term, 25.3% had a five-minute Apgar Score (AS5min of less than seven, 39.6% were nonvigorous at birth, 31.8% needed to be placed on mechanical ventilation, and 14.3% died during the hospitalization course. There was a significant relationship between the need for mechanical ventilation, nonvigorous state at the birth, complications of disease and mortality rate. Conclusions Despite the progress made in medicine, meconium aspiration syndrome is still one of the causes of newborn infants’ mortality. The mortality and morbidity rates can be reduced by improvement in perinatal care, prevention of post term delivery, timely caesarean and effective neonatal resuscitation at birth.

    The aim of the study was to investigate the effect of infection on sudden infant death syndrome (SIDS) and to analyse whether modifiable risk factors of SIDS, prone sleeping, covered head and smoking act as effect modifiers. In a consecutive multicentre case-control study of SIDS in Denmark, Norway...... growth and toxin or cytokine production, and also adds further support to a possible association between infection and SIDS by loss of protective mechanisms, such as arousal. The risk of SIDS among infants with the combined presence of infectious symptoms and either of the other modifiable risk factors......, prone sleeping, head covered or parental smoking, was far greater than the sum of each individual factor. These risk factors thus modify the dangerousness of infection in infancy....

    The aim of the paper is to describe the knowledge of mothers in Durban, South Africa, regarding risk factors of hearing loss in infants and their awareness of audiology services, and to describe their cultural beliefs about the risk factors for hearing loss in infants. A descriptive survey design with quantitative methods of analysis were used. Conveniently sampled mothers (n=102) receiving postnatal care for their infants from eight provincial clinics within Durban consented to participate, yielding a response rate of 48%. A questionnaire was used to collect the data and the Cronbach α was calculated yielding a score of 0.835, indicating good internal consistency and reliability of the questionnaire. Sixty percent of the mothers were aware of risk factors, such as middle ear infections, ototoxic medication and consumption of alcohol during pregnancy. Seventy percent were unaware that NICU/mechanical ventilation for more than 5 days, prematurity, rubella and jaundice are considered risk factors for hearing loss, implying a need to create awareness amongst mothers regarding such risk factors. Sixty percent (n=62) believed that bewitchment and ancestral curses can cause hearing loss. Cultural beliefs were associated with hearing loss, therefore, health professionals need to demonstrate cultural competence when providing audiology services, especially in a culturally and linguistically diverse countries such as South Africa. Although the mothers had an average knowledge about risk factors, two thirds did not know which professional to seek help from. There is a need to create awareness amongst mothers regarding the risk factors of infant hearing loss as well as audiology services in order to facilitate early detection and intervention. There is a need for health professionals to demonstrate cultural competence when working with their patients. PMID:28890772

    Full Text Available Abstract Background During and shortly after birth, newborn infants are colonized with enterococci. This study analyzes predictors for early enterococcal colonization of infants in a neonatal intensive care unit and describes risk factors associated with multidrugresistant enterococci colonization and its seasonal patterns. Methods Over a 12-month period, we performed a prospective epidemiological study in 274 infants admitted to a neonatal intensive care unit. On the first day of life, we compared infants with enterococcal isolates detected in meconium or body cultures to those without. We then tested the association of enterococcal colonization with peripartal predictors/risk factors by using bivariate and multivariate statistical methods. Results Twenty-three percent of the infants were colonized with enterococci. The three most common enterococcal species were E. faecium (48% of isolates, E. casseliflavus (25% and E. faecalis (13%. Fifty-seven percent of the enterococci found were resistant to three of five antibiotic classes, but no vancomycin-resistant isolates were observed. During winter/spring months, the number of enterococci and multidrug-resistant enterococci were higher than in summer/fall months (p = 0.002 and p Conclusion In neonatal intensive care units, an infant's susceptibility to early colonization with enterococci in general, and his or her risk for colonization with multidrug-resistant enterococci in particular, is increased in preterm newborns, especially during the winter/spring months. The prepartal use of antibiotics with no known activity against enterococci appears to increase the risk for colonization with multidrug-resistant enterococci.

    Gastroduodenal pathology, functional disorders and inflammatory diseases of the biliary tract take leading position among the diseases of the digestive system in children. Precisely these clinical forms are more intensive then other nosology. Continuous screening questionnaire of 786 children aged 1.5 to 7 years was carried out to study the prevalence and risk factors for diseases of the digestive system in children. Based on retrieved data was determined that 47,1 +/- 3,5% of children had symptoms of gastro-intestinal tract and biliary system diseases. They met 2.3 times more often in children aged 4 to 7 years, than in children from 1.5 to 3 years old. Immerced examination revealed that the incidence of dyskinesia of the biliary tract was 33 +/- 3,3%, chronic gastritis (CG) and gastroduodenitis (GDD)--6,2 +/- 1,8%, chronic cholecystitis--4,2 +/- 1,4%, functional disorders of the stomach (FGD)--2,8 +/- 1,2% and duodenal ulcer (DU)--0,3 +/- 0,4% of cases. In the structure of digestive diseases in children from 1.5 to 7 years in the first place were DBT--70%, the second--CGD and CG--14.7%--the third chronic cholecystitis--8.9%, the fourth--FGD--5.9% and in fifth place--DU-0.5% of cases. At the care record in the pediatric clinic with diseases of the digestive system were registered only 7,9 +/- 1,9% of children, which is 5.9 times lower accordinig to data of active diagnostic.

    Full Text Available Abstract Background While the importance of the infant-parent relationship from the child’s perspective is acknowledged worldwide, there is still a lack of knowledge about predictors and long-term benefits or consequences of the quality of parent-infant relationships from the parent’s perspective. The purpose of this prospective study is to investigate the quality of parent-infant relationships from parents’ perspectives, both in the prenatal and postpartum period. This study therefore focuses on prenatal (risk factors that may influence the quality of pre- and postnatal bonding, the transition to parenthood, and bonding as a process within families with young children. In contrast to most research concerning pregnancy and infant development, not only the roles and experiences of mothers during pregnancy and the first two years of infants’ lives are studied, but also those of fathers. Methods/design The present study is a prospective longitudinal cohort study, in which pregnant women (N = 466 and their partners (N = 319 are followed from 15 weeks gestation until their child is 24 months old. During pregnancy, midwives register the presence of prenatal risk factors and provide obstetric information after the child’s birth. Parental characteristics are investigated using self-report questionnaires at 15, 26, and 36 weeks gestational age and at 4, 6, 12, and 24 months postpartum. At 26 weeks of pregnancy and at 6 months postpartum, parents are interviewed concerning their representations of the (unborn child. At 6 months postpartum, the mother-child interaction is observed in several situations within the home setting. When children are 4, 6, 12, and 24 months old, parents also completed questionnaires concerning the child’s (social-emotional development and the parent-child relationship. Additionally, at 12 months information about the child’s physical development and well-being during the first year of life is retrieved from

The Bayley Scale of Infant Development (second edition) at 12 months of corrected age was used. The outcomes were the results of the clinical/neurological evaluation and the scores of the psychomotor development index (PDI) and mental development index (MDI) of the Bayley Scale of Infant Development II. The association between neonatal sepsis and neuromotor development and between neonatal sepsis and cognitive development was verified by logistic regression analysis. mean birth weight was 1,119g (SD: 247) and mean gestational age was 29 weeks and 6 days (SD: 2). Approximately 44.3%(n=86) of the infants had neonatal sepsis and 40.7% (n=79) had abnormal neuromotor development and/or abnormal psychomotor development index (PDI < 85) at 12 months of corrected age. On the mental scale, 76 (39.1%) children presented abnormal cognitive development (MDI<85). Children with neonatal sepsis were 2.5 times more likely to develop changes in neuromotor development (OR: 2.50; CI: 1.23-5.10). There was no association between neonatal sepsis and cognitive development impairment. neonatal sepsis was an independent risk factor for neuromotor development impairment at 12 months of corrected age, but not for mental development impairment.

    Human herpesvirus (HHV) infections are common during infancy. Primary infections are frequently asymptomatic and best studied prospectively by using direct viral detection. Oropharyngeal swab specimens were collected weekly from Ugandan newborn infants, their mothers, and other children in the household. Blood specimens were collected every 4 months. Samples were tested for herpes simplex virus (HSV) types 1 and 2, Epstein-Barr virus (EBV), cytomegalovirus (CMV), HHV-6A, HHV-6B, and HHV-8, using quantitative polymerase chain reaction. Thirty-two infants, 32 mothers, and 49 other household children were followed for a median of 57 weeks. Seventeen mothers had human immunodeficiency virus type 1 (HIV) infection; no infants acquired HIV-1. The 12-month incidence of postnatal infection was 76% for HHV-6B, 59% for CMV, 47% for EBV, 8% for HSV-1, and 0% for HHV-8. The quantity of oropharyngeal shedding by contacts was associated with HHV-6A or HHV-6B transmission. Maternal HIV-1 infection was associated with EBV transmission, while breastfeeding and younger child contacts were associated with CMV transmission. Except for HSV-1, primary HHV infections were subclinical. By capturing exposures and acquisition events, we found that the incidence and risk factors of infection vary by HHV type. HSV-1 infection, unlike other HHV infections, caused acute clinical illness in these infants. © The Author 2016. Published by Oxford University Press for the Infectious Diseases Society of America.

    Abstract An epidemic of urinary tract stones was noted among infants in China, 2008. This event was believed to be associated with consumption melamine-contaminated powdered formula. The patients with symptoms and clinical manifests had already been analyzed in our previous studies. In this study, our aim is to investigate the risk factors of melamine-associated acute kidney injury (AKI) and the potential relationship toward children growth in our five years follow-up. A total of 619 infants with melamine-associated urolithiasis were admitted into 20 different hospitals in the Gansu province, China. All clinical data were divided into AKI and control groups according to the occurrence of AKI. Univariate and multivariate analyses were performed with a logistic regression model to assess the independent risk factors of AKI. Logistic regression analysis revealed that the odds ratio (OR) of AKI was 19.62 in the group of infants who consumed Sanlu® milk powdered infant milk formula. A higher prevalence of AKI was observed in infants age of 6-11 months (OR: 9.59, p melamine infant formula (Sanlu® milk powdered infant formula), age (6-17 months) and symptoms of URTI, diarrhea, dehydration or fever were risk factors of AKI in infants with melamine-associated urolithiasis.

Materials and Method: Infants with ≤32 weeks of gestational age and ≤1500 grams of birth weight were included in the study. Maternal demographic characteristics and pregnancy history, antenatal and postnatal follow-up problems, antenatal steroid treatment, modes of delivery (NVY, C/S, and the babies’ birth history were recorded. The duration of ventilation treatment and the number of transfusions applied before the diagnosis of NEC in premature infants were recorded. Patients with stage II and stage III NEC were included in the study.Results: Sixty one of 532 patients (11,4% were diagnosed as NEC and allocated in the study group. Sixty patients were enrolled as the control group. There were no differences between both groups with respect to demographic characteristics, APGAR score, need for resuscitation and antenatal steroid treatment. The duration of ventilation treatment (p=0.037 and the frequency of red blood cell transfusion (p=0.032 were considered to be higher in the NEC group. Antenatal steroid administration was higher in patients with stage 2 NEC (p=0.011, but the duration of ventilation treatment was higher in those with stage 3 (p=0.020. The mortality rate was 31.1% in the patients with NEC. It was observed that 83% of patients who died had stage 3 NEC and a lower birth weight and gestational age. Respiratory distress syndrome (RDS (p=0.02, togetherness of RDS and patent ductus arteriosus (PDA were higher in the NEC group (p=0.03, and more intracranial hemorrhage (ICH was detected at stage 3 NEC (p=0.034.

    There is a concern that allergic disease in childhood is higher than expected in Cuba. The aim of this study was to determine the risk factors for eczema of infants aged 12-15 months living in Havana. We used a cross-sectional epidemiological study design. Data on eczema symptoms and a wide range of lifestyle factors were collected by researcher administered questionnaires. Data were collected on 1956 children (96% response rate), of whom 672 (34%) were reported as having had eczema. Independent risk factors for eczema included young maternal age (adjusted odds ratio (OR) 0.98 per additional year of age; 95% confidence interval (CI) 0.97-0.99), child's weight (OR 1.13 per additional kg; 95% CI: 1.03-1.25), insect sting allergy (OR 2.11; 95% CI: 1.33-3.35), rodents in the home (OR 1.39; 95% CI: 1.10-1.76), attendance at childcare facilities (OR 1.34: 95% CI: 1.05-1.70) and self-reported mould in the home (OR 1.23; 95% CI: 1.07-1.41). Infant exposure to paracetamol was associated with an increased risk of eczema even after adjustment for wheeze (OR 1.22; 95% CI: 1.03-1.46). Despite a very different culture and environment, the consistency of these findings with those from more economically developed countries suggests potential causal associations. The association with paracetamol, even after adjustment for wheeze, suggests that intervention studies are required in young infants, to ascertain if this commonly used anti-pyretic medication increases allergic disease.

    Full Text Available BACKGROUND: Low birth weight followed by accelerated weight gain during early childhood has been associated with adverse metabolic and cardiovascular outcomes later in life. The aim of this study was to examine the impact of early infant weight gain on glucose metabolism and cardiovascular risk factors in adolescence and to study if the effect differed between adolescents born small for gestational age (SGA vs. appropriate for gestational age (AGA. METHODOLOGY/PRINCIPAL FINDINGS: Data from 30 SGA and 57 AGA healthy young Danish adolescents were analysed. They had a mean age of 17.6 years and all were born at term. Data on early infant weight gain from birth to three months as well as from birth to one year were available in the majority of subjects. In adolescence, glucose metabolism was assessed by a simplified intravenous glucose tolerance test and body composition was assessed by dual-energy X-ray absorptiometry. Blood pressures as well as plasma concentrations of triglycerides and cholesterol were measured. Early infant weight gain from birth to three months was positively associated with the fasting insulin concentration, HOMA-IR, basal lipid levels and systolic blood pressure at 17 years. There was a differential effect of postnatal weight gain on HOMA-IR in AGA and SGA participants (P for interaction = 0.03. No significant associations were seen between postnatal weight gain and body composition or parameters of glucose metabolism assessed by the simplified intravenous glucose tolerance test. In subgroup analysis, all associations with early infant weight gain were absent in the AGA group, but the associations with basal insulin and HOMA-IR were still present in the SGA group. CONCLUSION: This study suggests that accelerated growth during the first three months of life may confer an increased risk of later metabolic disturbances--particularly of glucose metabolism--in individuals born SGA.

    The objective of this study was to estimate the prevalence of hearing impairment in children in a public hospital in Belo Horizonte, Minas Gerais, Brazil, and to investigate the association with risk factors described in the literature. This study was cross-sectional and retrospective and analyzed 798 newborns and infants evaluated in the Universal Neonatal Hearing Screening Program from June 2002 to December 2003. The risk factors established by the Joint Committee on Infant Hearing in 1994 and Azevedo in 1996 were studied, besides prematurity. Prevalence of hearing impairment was 1.8% (15 cases). A multivariate logistic regression analysis was used to verify associations between risk factors and hearing impairment, showing a significant statistical association (p ototoxic drugs, and low birth weight. A significant prevalence of hearing impairment in neonates and infants was confirmed. Attention should thus be focused on risk factors for hearing impairment, using hearing programs that ensure prevention, early detection, and intervention.

MÉTODOS: Estudo retrospectivo de dados secundários de 22.452 fichas coletadas ao nascimento, de janeiro de 1998 a dezembro de 2001. A variável dependente foi o óbito pós-neonatal. As variáveis independentes foram: peso ao nascer OBJECTIVE: To assess, among the criteria adopted by the Program of Neonates at Risk of the Health Department of the Municipality of Santos, São Paulo, Brazil, the risk factors for post-neonatal infant mortality. METHODS: In a retrospective study, data from 22,452 newborn charts, from 1998 to 2001, were retrieved. Logistic regression was applied to detect risk factors for the dependent variable: death between 29 days and one year old. The independent variables were: birth weight <2,500g, congenital malformation, unwanted pregnancy, need of hospitalization after mother's discharge, unemployed house chief, siblings <2 years old and single mother. RESULTS: During the studied period, among the 22,452 children, there were 97 deaths of children between 29 days and one year old. In the bivariate analysis, the variables "birth weight <2,500g", "congenital malformations", "need of hospitalization after mother's discharge", "unemployed house chief", "siblings <2 years" and "single mother" were significantly associated to post-neonatal death. By logistic regression analysis, "birth weight <2.500g", "congenital malformations", "need of hospitalization after mother's discharge" and "siblings <2 years old" were significantly associated to post-neonatal mortality. CONCLUSIONS: The criteria adopted by the Program of Neonates at Risk were useful to identify infants at risk for death from 29 days to one year of life.

    Full Text Available Clinical course, prognosis and mechanisms of separate forms of heart rhythm disorders in children differ from those in adults. Especially, it refers to new-borns and infants whose conduction system differs by functional and morphologic immaturity. In connection with it, the assessment of natural history of heart rhythm disorders, occurred in a perinatal period, and determination of risk factors of arrhythmia appearance in infants are of some interest. 88 newborns took part in the study. The patients were involved by continuous sampling technique. Risk factors, occurred in a perinatal period and potentially influenced on development of heart rhythm disorders, were assessed. In our study we took biological, gynecologic and obstetric history, data of gestation and delivery course, early and late neonatal period, early infancy, Echo, neurosonography, Holter monitoring with determination of heart rhythm variability, and determined thyroid hormonal status. Maximum specific gravity had extrasystoles – 32.4% – in the structure of idiopathic arrhythmias in infants. Heart rhythm disorders with natural history were kept at six months of life only in 5,4% of children. Persistence of arrhythmias was marked during one year only for WPW syndrome. Heart rhythm disorders are often marked significantly in children whose mothers had acute respiratory disease during the pregnancy, or if the children were born from the first pregnancy, had the signs of central nervous system damage syndromes in an early perinatal period (arrest, intracranial hypertension, convulsive disorder. Disorders of autonomic imbalance of cardiac function and peculiarities of hemodynamics of pulmonary circulation contribute significantly into appearance and persistence of all types of arrhythmias. On the whole, the prognosis of heart rhythm disorders, occurred in the perinatal period, without organic and structural changes of myocardium is favorable. The exclusion can be made for

    This study examined short-term attachment stability and sought to identify predictors of stability and change within a sample characterized by fathers' alcoholism. Results suggest moderate stability of attachment classifications (60% for mothers, 53% for fathers) from 12 to 18 months. Higher paternal and maternal alcohol symptoms, maternal depression, and maternal antisocial behavior were found in families with stable insecure mother-infant attachment compared to those who were stable secure. Mother-infant stable insecurity was associated with higher levels of maternal negative affect expression during play. Father-infant stable insecurity was associated with lower levels of paternal positive affect expression and decreased sensitivity during play. Stable insecure children also had higher levels of negative affect during parent-infant interactions and higher negative emotionality during other episodes compared to stable secure children. Results indicate that infants who were insecure at both time points had the highest constellation of family risk characteristics.

    Full Text Available Introduction: It is known that the HLA genotype can explain about a 40% of the genetic risk of celiac disease (CD, thus, other genetic predisposing factors as well as factors that subtly modulate T cell activation and differentiation need to be studied. This includes environmental factors that are currently believed to impact on the immune system and gut microbiota development. Aim: To assess the associations between early environmental factors (EEF, lymphocyte subsets, and intestinal microbiota composition in infants at familial risk for CD. Study design: Prospective observational study. Subjects: Fifty-five 4 month-old infants with at least a first-degree relative suffering CD. Infants were classified according to type of delivery, mother's antibiotic intake during pregnancy and during labor, milk-feeding practices, early infections and antibiotic intake, rotavirus vaccine administration, and allergy incidence within the first 18 months of life. Methods: Lymphocyte subsets and gut microbiota composition were studied at the age of 4 months. Results: Formula feeding and infant's infections were associated with higher CD3+, CD4+, CD4+CD38+, CD4+CD28+ and CD3+CD4+CD45RO+ counts (P0.01. Infant s infections were also associated with higher CD4+CD25+, CD4+HLA-DR+ and NK cell counts (P0.01. Cesarean delivery and rotavirus vaccine administration were associated with lower percentage of CD4+CD25+ cells. Infant's antibiotic intake was associated and correlated with lower counts of Bifidobacterium longum and higher counts of Bacteroides fragilis group. Conclusions: Infant s infections and antibiotic intake in the first 4 months of life are the EEF more strongly and/or frequently associated to lymphocyte subpopulations and microbiota composition, respectively, in infants at risk of CD.

    The role of fathers in the development of obesity in their offspring remains poorly understood. We evaluated associations of missing paternal demographic information on birth certificates with perinatal risk factors for childhood obesity. Data were from the Linked CENTURY Study, a database linking birth certificate and well-child visit data for 200,258 Massachusetts children from 1980-2008. We categorized participants based on the availability of paternal age, education, or race/ethnicity and maternal marital status on the birth certificate: (1) pregnancies missing paternal data; (2) pregnancies involving unmarried women with paternal data; and (3) pregnancies involving married women with paternal data. Using linear and logistic regression, we compared differences in smoking during pregnancy, gestational diabetes, birthweight, breastfeeding initiation, and ever recording a weight for length (WFL) ≥ the 95th percentile or crossing upwards ≥2 WFL percentiles between 0-24 months among the study groups. 11,989 (6.0 %) birth certificates were missing paternal data; 31,323 (15.6 %) mothers were unmarried. In adjusted analyses, missing paternal data was associated with lower birthweight (β -0.07 kg; 95 % CI: -0.08, -0.05), smoking during pregnancy (AOR 4.40; 95 % CI: 3.97, 4.87), non-initiation of breastfeeding (AOR 0.39; 95 % CI: 0.36, 0.42), and with ever having a WFL ≥ 95th percentile (AOR 1.10; 95 % CI: 1.01, 1.20). Similar associations were noted for pregnancies involving unmarried women with paternal data, but differences were less pronounced. Missing paternal data on the birth certificate is associated with perinatal risk factors for childhood obesity. Efforts to understand and reduce obesity risk factors in early life may need to consider paternal factors.

    . PATIENT AND METHODS: This is a case-control study. The sample consisted of 212 infants under 24 months, hospitalized with acute diarrhea, at the "Instituto Materno-Infantil de Pernambuco", Recife, PE, Brazil. Cases were infants with persistent diarrhea and controls those with acute diarrhea. Cases and controls were compared to a series of socio-economic, biological and clinical variables, previous morbidities and therapeutic management prior to hospital admission. Unadjusted and adjusted odds ratio were used with the respective 95% confidence intervals. It was adopted the level of significance of 5%. Logistic regression analysis was conducted to control for potential confounding factors. RESULTS: The risk of persistent diarrhea was higher for infants with: dysentery, fever at the onset of diarrhea, fasting and taking antibiotics prior to hospital admission. The variables that showed the highest adjusted odds ratios for persistent diarrhea were infants living in households without refrigerator and perianal hyperemia at hospital admission. CONCLUSIONS: The improvement of environmental conditions and an adequate clinical management of diarrhea for hospitalized infants may contribute to the reduction of diarrhea morbidity.

    Iodine deficiency is responsible for a higher mortality and morbidity in neonates and infants. It has not yet disappeared in European countries, especially in Southern and Eastern Europe. The present study aimed at evaluating the status of iodine nutrition of infants living in the North department (France) and at studying risk factors for iodine deficiency. The study was conducted in primary health care centres in 160 healthy infants aged ten days to six years (mean +/- SD: 17.7 +/- 2.5 months). Data included: familial thyroid disease history, type of feeding at inclusion, timing of introduction of complementary foods, nutritional status (weight, height, head and arm circumference), as well as maternal education level and family socio-economical status. Iodine status was assessed by urinary iodine excretion. Urinary iodine concentration ranged from 4 to 1042 microg/l (median +/- SD: 195,5 +/- 21,6 microg/l). Thirty-eight (24%) of 160 children were iodine deficient (urinary iodine iodine deficiency (50-99 microg/l: 17%), moderate iodine deficiency (20-49 microg/l: 5%), severe iodine deficiency (iodine status and age, sex, geographic origin of the children, as well as social and occupational group of the parents. Breast-feeding did not prevent from iodine deficiency. Iodine status did not differ between the cow's milk fed group and the group that was not fed cow's milk. Formula feeding was associated with iodine deficiency (p = 0,02). Prevalence of severe iodine deficiency was very low in this population. However, iodine status was not optimal.

    Full Text Available Abstract Background Infant mortality is an important indicator of population health in a country. It is associated with several health determinants, such as maternal health, access to high-quality health care, socioeconomic conditions, and public health policy and practices. Methods A spatial-temporal analysis was performed to assess changes in infant mortality patterns between 1992-2007 and to identify factors associated with infant mortality risk in the Agincourt sub-district, rural northeast South Africa. Period, sex, refugee status, maternal and fertility-related factors, household mortality experience, distance to nearest primary health care facility, and socio-economic status were examined as possible risk factors. All-cause and cause-specific mortality maps were developed to identify high risk areas within the study site. The analysis was carried out by fitting Bayesian hierarchical geostatistical negative binomial autoregressive models using Markov chain Monte Carlo simulation. Simulation-based Bayesian kriging was used to produce maps of all-cause and cause-specific mortality risk. Results Infant mortality increased significantly over the study period, largely due to the impact of the HIV epidemic. There was a high burden of neonatal mortality (especially perinatal with several hot spots observed in close proximity to health facilities. Significant risk factors for all-cause infant mortality were mother's death in first year (most commonly due to HIV, death of previous sibling and increasing number of household deaths. Being born to a Mozambican mother posed a significant risk for infectious and parasitic deaths, particularly acute diarrhoea and malnutrition. Conclusions This study demonstrates the use of Bayesian geostatistical models in assessing risk factors and producing smooth maps of infant mortality risk in a health and socio-demographic surveillance system. Results showed marked geographical differences in mortality risk across

    Preterm birth and small for gestational age (SGA) are strong indicators of neonatal adverse outcomes. With the growing importance of preterm SGA infants, we aim to evaluate the prevalence and risk factors for preterm SGA in China. We analyzed the data of parents and infants from a population-based cohort research of the free National Pre-pregnancy Checkups Project (NPCP) in rural China. Only singleton live births that occurred between 24 weeks +0 days and 36 weeks +6 days of pregnancy were included in this study. SGA was defined as birth weight less than the 10th percentile of the reference birth-weight-for-gestational-age population. A multiple logistic regression model was built using the statistically significant variables from the 371 variables in the questionnaire. A total of 11,474 singleton, preterm, live-birth infants were included. Of the total infants, 317 (2.77%) were preterm SGA infants. A higher risk of preterm SGA infants was observed among mothers who were on oral contraceptives (OR: 8.162, 95% CI: 1.622-41.072), mothers who had syphilis (OR: 12.800, 95% CI: 1.250-131.041), and mothers with a high eosinophil percentage (OR: 13.292, 95% CI: 1.282-135.796). Maternal intake of folic acid at least 3 months before pregnancy (OR: 0.284, 95% CI:0.124-0.654) and paternal intake of egg and meat (OR: 0.097,95% CI:0.030-0.315) were protective factors. Compared with North China, the incidence of preterm SGA infants was higher in South China. Preterm SGA infants were associated with both maternal and paternal factors.

    Full Text Available Background: The association between birth outcomes and child maltreatment remains controversial. The purpose of this study is to test whether infants without congenital or chronic disease who are low birth weight (LBW, preterm, or small for gestational age (SGA are at an increased risk of being maltreated.Methods: A hospital-based case-control study of infants without congenital or chronic diseases who visited the National Center for Child Health and Development, Tokyo, between April 1, 2002 and March 31, 2005 was conducted. Cases (N = 35 and controls (N = 29 were compared on mean birth weight, gestational age, and z-score of birth weight.Results: SGA was significantly associated with infant maltreatment after adjusting for other risk factors (adjusted odds ratio: 4.45, 95% CI: 1.29–15.3. LBW and preterm births were not associated with infant maltreatment.Conclusion: Infants born as SGA are 4.5 times more at risk of maltreatment, even if they do not have a congenital or chronic disease. This may be because SGA infants tend to have poorer neurological development which leads them to be hard-to-soothe and places them at risk for maltreatment.

    Maternal prepregnancy obesity has been linked to the offspring's risk for subsequent asthma. We determined whether maternal obesity is associated with increased risk of wheezing phenotypes early in life. We used data on 1107 mother-child pairs from two birth cohorts from the INMA-INfancia y Medio Ambiente project. Maternal height was measured and prepregnancy weight self-reported at enrolment (on average at 13.7 ± 2 weeks of gestation). Maternal prepregnancy body mass index was categorised as underweight, normal, overweight and obese according to WHO recommendations. Information on child's wheezing was obtained through questionnaires up to the age of 14 (± 1) months. Wheezing was classified as infrequent (<4 reported wheezing episodes) or frequent (≥ 4 episodes). Weight and length of infants were measured by trained study staff at 14.6 (± 1) months of age and weight-for-length z-scores computed. Although maternal obesity did not increase the risk of the child to have any or infrequent wheezing, children of obese mothers were more likely to have frequent wheezing than children of normal-weight mothers (11.8% vs. 3.8%; P = 0.002). In fully adjusted multinomial logistic regression models, including infants' weight-for-length z-scores and other covariates, maternal prepregnancy obesity was associated with increased risk of frequent [adjusted relative risk (RR) 4.18, 95% confidence interval (CI) 1.55, 11.3] but not infrequent (RR 1.05 [95% CI 0.55, 2.01]) wheezing in their children. Maternal prepregnancy obesity is independently associated with an increased risk of frequent wheezing in the infant by the age of 14 months. These findings add evidence on the potential effects of in utero exposures on asthma-related phenotypes. © 2012 Blackwell Publishing Ltd.

    Conclusions: The rate of Type I ROP in this study is higher than that in previous studies due to the higher number of infants with BW <1000 g in our cohort and the treatment of more eyes with stage 2+ ROP. However, all the treated eyes had a favorable outcome. Gestational age at birth and number of ventilated days were independent risk factors for the development of Type I ROP.

    Full Text Available Results of observation of children from 2,5 months to 4 years old, treated in hospital with diagnosis chronic diarrhea are analyzed in this article. Diarrhea debuted in first year of living in most cases. The reason of onset of diarrhea often was alimentary factor. Hereditary predisposition, pathologic pregnancy, and diseases in women at the time of pregnancy played an important role in development of disease. Nutrition of children in early age was characterized by low duration of breast feeding and early conversion of children to the mixed and artificial feeding. Main food stuffs in children's nutrition on mixed and artificial feeding was adapted milk formulas, and rarely non adapted milk food (cow's and goat's milk, kefir.

    Violence against women may have an impact on infant and child mortality. We aimed to determine whether domestic violence is a risk factor for infant and child death. Eighty infant and child deaths (under 5 years of age) were identified from a central register of a comprehensive community health programme in rural southern India; controls were matched for age, gender and street of residence. Domestic violence during the lifetime (OR 2.63, 95% CI 1.39-4.99), which was severe (OR 4.00, 95% CI 2.02-7.94) and during pregnancy (OR 5.69, 95% CI 2.03-15. 93) and father's smoking status (OR 3.81, 95% CI 1.92-7.55) were significantly related to infant and child death while immunization being completed for age (OR 0.04, 95% CI 0.01-0.19) and having at least one boy child in the family (OR 0.29, 95% CI 0.14-0.59) were protective. These variables remained statistically significantly associated with outcome after adjusting for other determinants using conditional logistic regression. There is evidence for an association between domestic violence in mothers, and infant and child death. Copyright 2013, NMJI.

    Full Text Available Abstract Background The optimal treatment regimen or protocol for managing a persistent patent ductus arteriosus (PDA in extremely low birth weight (ELBW infants has not been well established. This study was aimed at evaluating the failure rate of a cyclooxygenase (COX inhibitor (COI for PDA closure and to determine the incidence of a PDA requiring ligation in ELBW infants. We examined the clinical characteristics and risk factors that may predict the clinical consequences of failure of PDA closure by COI. Methods Medical information on 138 infants with birth weight (BW 48 hours was retrieved. Clinical characteristics and outcomes of patients whose PDAs closed with COI were compared with those who did not close. Results Of the 138 patients, 112 survived to discharge. Eighty (71.4% of those who survived received 1-3 courses of COI treatment for a symptomatic PDA. A total of 32 (40% failed COI treatment and underwent PDA ligation. Multivariable logistic regression analysis suggests that the observed differences in the outcomes in infants with or without symptomatic PDA can be explained by the babies with symptomatic PDA being more immature and sicker. No significant difference was seen in the incidence of chronic lung disease (CLD in infants whose PDA was treated medically versus those who failed medical treatment and then underwent ligation. However, after adjusting for disease severity and other known risk factors, the odds ratio of developing CLD for surviving babies with a persistent PDA compared to those whose PDA was successfully closed with 1-2 courses of COI is 3.24 (1.07-9.81; p = 0.038. Conclusions When successfully treated, PDA in ELBW infants did not contribute significantly to the adverse outcomes such as CLD, retinopathy of prematurity (ROP and age at discharge. This suggests that it is beneficial for a hemodynamically significant PDA to be closed. The failure of a repeat course of COI to close a PDA is a major risk factor for

The main clinical outcomes were occurrence of any stage of ROP and in particular severe ROP. Perinatal variables considered were: birth weight, gestational age, gender, method of ventilation (nasal continuous airway pressure or intermittent mechanical ventilation, packed red blood cell and/or plasma transfusion, occurrence of sepsis, neonatal indirect hyperbilirubinemia, intraventricular hemorrhage, and patent ductus arteriosus. After obtaining informed consent from the parents, infants at risk were examined for ROP using indirect ophthalmoscopy, ie, RetCam II fundus photography.Results: The study included 152 infants of mean gestational age 31.02 weeks and mean birth weight 1.229 kg. Seventy-two cases (47.5% were male and 80 cases (52.5% were female. Of the cases screened, 100 (65.6% had no ROP, 52 had ROP of any stage (34.4%, and 27 (18% had stage 1, five (3.3% had stage 2, 17 (11.5% had stage 3, and three (1.6% had stage 4 disease. No infants had stage 5 ROP. Of all our cases with ROP, 15 (28.6% had prethreshold disease type 1 that required treatment, comprising 9.8% of all cases screened for ROP. Using stepwise logistic regression analysis, all risk factors studied were found to be significantly associated with the development of ROP, except for neonatal indirect hyperbilirubinemia. Severity of ROP was inversely proportional to birth weight and gestational age.Conclusion: ROP occurred in 34.4% of all infants screened in the neonatal intensive

    The infant mortality rate (IMR) among single and twin births from 1999 to 2008 was analyzed using Japanese Vital Statistics. The IMR was 5.3-fold higher in twins than in singletons in 1999 and decreased to 3.9-fold in 2008. The reduced risk of infant mortality in twins relative to singletons may be related, partially, to survival rates, which improved after fetoscopic laser photocoagulation for twin - twin transfusion syndrome. The proportion of neonatal deaths among total infant deaths was 54% for singletons and 74% for twins. Thus, intensive care of single and twin births may be very important during the first month of life to reduce the IMR. The IMR decreased as gestational age (GA) rose in singletons, whereas the IMR in twins decreased as GA rose until 37 weeks and increased thereafter. The IMR was significantly higher in twins than in singletons from the shortest GA (twins from 30 to 36 weeks. As for maternal age, the early neonatal and neonatal mortality rates as well as the IMR in singletons were significantly higher in the youngest maternal age group than in the oldest one, whereas the opposite result was obtained in twins. The lowest IMR in singletons was 1.1 per 1,000 live births for ≥38 weeks of gestation and heaviest birth weight (≥2,000 g), while the lowest IMR in twins was 1.8 at 37 weeks and ≥2,000 g.

    Full Text Available Asphyxia is a risk factor that is very often related to neuro-developmental issues in high risk infants and equally affects preterm and term infants, however its outcome on the developed brain differs from the outcome on the preterm brain.In preterm infants, asphyxia usually exerts a hemorrhagic or ischaemic event and periventricular leukomalacia.In term infants, asphyxia leads to cerebral edema and atrophy of the brain, which may later lead to hypoxic ischaemic encephalopathy (HIE.The number of term infants with HIE who have survived is lower than those of preterm infants, while the percentage of term infants with HIE who have neuro-developmental issues is higher. Preemies face more problems in their motor development as a result of the brain damage, while term infants suffer from encephalopathy and their cognitive abilities are more affected.We have conducted a study about the effects that asphyxia has on the developmental outcomes in high risk infants. In our study, we did a longitudinal developmental follow-up of 30 high risk infants and an evaluation of their developmental outcome using the Griffiths Mental Development Scales, from the 4th month of life until the end of the 36th month. First, we found that high risk infants had a much lower developmental outcome than the control group during the trial. Finally, we found that asphyxia makes a difference in the developmental outcome of preterm infants without asphyxia who have a very low birth weight, the preterm infants with asphyxia, and the term infants with HIE-II.

    Full Text Available Percutaneously inserted central catheters (PICCs are often used in neonatal medicine. Venous thrombosis (VT is one of the complications associated with PICC use. According to some reports, fresh frozen plasma (FFP may be a risk factor for VT. The purpose of this study was to determine whether FFP use is associated with VT in extremely low birth weight infants (ELBWIs. We performed a matched case-control study on risk factors for VT in ELBWIs born over a period of 5 years in the neonatal intensive care unit of a tertiary hospital. Controls were infants from the unit matched for gestational age and birth weight. We performed univariate analyses and created receiver operating characteristic (ROC curves for the cut-off values of continuous parameters such as FFP. We also conducted multivariate conditional logistic regression analysis and calculated adjusted odds ratios and their 95% confidence intervals. Thirteen VT cases and 34 matched controls were examined. Using an ROC curve, FFP by day 5>50mL/kg was selected as the cut-off value. In multivariate conditional logistic regression analysis, FFP by day 5>50mL/kg exhibited an adjusted odds ratio of 5.88 (95% confidence interval:1.12-41.81, p=0.036. FFP by day 5>50mL/kg may be a risk factor for VT in ELBWIs.

    Full Text Available Objectives: We explore the complex factors associated with infant feeding by analyzing what mother, infant, and household factors are associated with the types of food given to infants. We seek to quantify associations in order to inform public health policy about the importance of target populations for infant feeding programs. Methods: We used data from the Demographic Health Survey in 20 developing countries for multiple years to examine mother, infant, and household factors associated with six types of food given to infants (exclusive breastfeeding, non-exclusive breastfeeding, infant formula, milk liquids, non-milk liquids, and solid foods. We performed a seemingly unrelated regressions analysis with community-year fixed effects to account for correlation between food types and control for confounding factors associated with community resources, culture, time period, and geography in the pooled analysis.Results: We found that several mother, infant, and household characteristics were associated with each of the feeding types. Most notably, mother’s education, working status, and weight are significantly associated with the type of food given to infants. We provide quantified estimates of the association of each of these variables with six types of food given to infants. Conclusions: By identifying maternal characteristics associated with infant feeding and quantifying those associations, we help public health policymakers generate priorities for targeting infant feeding programs to specific populations that are at greatest risk. Higher educated, working mothers are best to target with exclusive breastfeeding programs for young infants. Mothers with lower education are best to target with complementary feeding programs in infants older than 1 year. Finally, while maternal weight is associated with higher levels of exclusive breastfeeding the association is too weak to merit targeting of breastfeeding programs to low-weight mothers.

    Full Text Available Background: Since its recognition two decades ago, HIV/AIDS remains a major global challenge. Infants contract the infection from their mother in the womb, during birth and breast feeding. In Ethiopia, limited information is available in relation to mother to child transmission (MCT. Objective: To determine the prevalence of HIV infection among infants born from HIV seropositive mothers and identify associated risk factors. Method: Hospital based retrospective record review was employed on 159 infants born from HIV seropositive mothers. Data was collected from the pediatric HIV log book using a structured questionnaire. Data was entered in to excel sheet, cleaned and then exported to STATA and analyzed using appropriate statistical tools. Result: The study revealed that 32.1% (51/159 of the infants born from HIV seropositive mothers were found to be HIV positive. Majority of the infants were born in health institutions and their birth was attended by health professionals. The rate of HIV transmission was about 3 times higher in those born at home and assisted by traditional birth attendants (TBA than those born at health institutions and assisted by health professionals (58.5% versus 22,9%; P 0.004. The data also revealed a significant association between HIV infection and feeding practice (p 0.004 which was 45.4% (25/55 in those who practice mixed feeding, 34% (18/53 in those practicing exclusive breast feeding and 15.7% (8/51 among those with replacement feeding. Conclusion: The vertical transmission rate of 32.1% observed in the present study is quite high and is within the estimated range for Sub saharan African countries.

  2. Factors that elevate the internal radionuclide and chemical retention, dose and health risks to infants and children in a radiological-nuclear emergency.

    2009-06-01

    The factors that influence the dose and risk to vulnerable population groups from exposure and internal uptake of chemicals are examined and, in particular, the radionuclides released in chemical, biological, radiological, nuclear and explosive events. The paper seeks to identify the areas that would benefit from further research. The intake and body burdens of carbon and calcium were assessed as surrogates for contaminants that either act like or bind to hydrocarbons (e.g. tritium and (14)C) or bone-seeking radionuclides (e.g. (90)Sr and (239)Pu). The shortest turnover times for such materials in the whole body were evaluated for the newborn: 11 d and 0.5 y for carbon and calcium, respectively. However, their biokinetic behaviour is complicated by a particularly high percentage of the gut-absorbed dietary intake of carbon (approximately 16%) and calcium (approximately 100%) that is incorporated into the soft tissue and skeleton of the growing neonate. The International Commission on Radiological Protection dose coefficients (Sv Bq(-1)) were examined for 14 radionuclides, including 9 of concern because of their potential use in radiological dispersal devices. The dose coefficients for a 3-month-old are greater than those for adults (2-56 times more for ingestion and 2-12 times for inhalation). The age-dependent dose and exposure assessment of contaminant intakes would improve by accounting for gender and growth where it is currently neglected. Health risk is evaluated as the product of the exposure and hazard factors, the latter being about 10-fold greater in infants than in adults. The exposure factor is also approximately 10-fold higher for ingestion by infants than by adults, and unity for inhalation varying with the contaminant. Qualitative and quantitative physiological and epidemiological evidence supports infants being more vulnerable to cancer and neurological deficit than older children.

    Intraventricular hemorrhage is a major risk factor for neurodevelopmental disabilities in preterm infants. However, few studies have investigated how pregnancy complications responsible for preterm delivery are related to intraventricular hemorrhage. We sought to investigate the association between the main causes of preterm delivery and intraventricular hemorrhage in very preterm infants born in France during 2011 between 22-31 weeks of gestation. The study included 3495 preterm infants from the national EPIPAGE 2 cohort study who were admitted to neonatal intensive care units and had at least 1 cranial ultrasound assessment. The primary outcome was grade I-IV intraventricular hemorrhage according to the Papile classification. Multinomial logistic regression models were used to study the relationship between risk of intraventricular hemorrhage and the leading causes of preterm delivery: vascular placental diseases, isolated intrauterine growth retardation, placental abruption, preterm labor, and premature rupture of membranes, with or without associated maternal inflammatory syndrome. The overall frequency of grade IV, III, II, and I intraventricular hemorrhage was 3.8% (95% confidence interval, 3.2-4.5), 3.3% (95% confidence interval, 2.7-3.9), 12.1% (95% confidence interval, 11.0-13.3), and 17.0% (95% confidence interval, 15.7-18.4), respectively. After adjustment for gestational age, antenatal magnesium sulfate therapy, level of care in the maternity unit, antenatal corticosteroids, and chest compressions, infants born after placental abruption had a higher risk of grade IV and III intraventricular hemorrhage compared to those born under placental vascular disease conditions, with adjusted odds ratios of 4.3 (95% confidence interval, 1.1-17.0) and 4.4 (95% confidence interval, 1.1-17.6), respectively. Similarly, preterm labor with concurrent inflammatory syndrome was associated with an increased risk of grade IV intraventricular hemorrhage (adjusted odds ratio

    Objective: Bed-sharing is associated with sudden infant death syndrome and accidental suffocation and strangulation in bed. The purpose of this study was to identify risk factors for newborn bed-sharing. Methods: Postpartum mothers from a university maternity service were contacted by phone to complete a survey. Demographic and environmental data were collected; newborn bed-sharing and sleep environment were self-reported. Results: A total of 1261 mothers completed surveys; bed-sharing was reported by 79 mothers (6.3%). Multivariate logistic regression identified referral to a nurse (odds ratio [OR] = 10; 95% confidence interval [CI] = 4.5-30) and sleep location “other” than a crib, bassinet, or Pack and Play (OR = 7.1; 95% CI = 1.9-25.9) as factors associated with an increased risk of bed-sharing; formula feeding (OR = 0.4; 95% CI = 0.20-0.77) and crib sleeping (OR = 0.49; 95% CI = 0.26-0.86) reduced this risk. Conclusion: Infants with no identifiable places to sleep, significant health issues, and who are breastfed are more likely to bed-share. Interventional studies should be directed at these factors.

METHODS: Neonates with gestational age <37wks and/ or birth weight ≤ 2500gms born over one year period were examined by indirect ophthalmoscopy between 2 to 4 weeks after birth, and followed up till retinal vascularization was complete. Maternal and neonatal risk factors were noted and data analyzed by statistical package SPSS-15. RESULTS: 100 babies were thus examined. The overall incidence of retinopathy of prematurity was 40%, 22%in babies’ ≤34wks of gestation and 52% in babies with a birth weight1500-2000g. Majority were in stage 2. Gestational age (<32weeks, Birth weight (<1500g, RDS, surfactant therapy, PDA were found to be risk factors. CONCLUSION: Meticulous fundus examination with indirect ophthalmoscopy in all preterm babies with gestational age<37weeks and birth weight ≤ 2500gms is essential noninvasive method for early detection of ROP and its progression. Screening should be intensified in the presence of factors like RDS, oxygen administration and presence of PDA

    Many infants with complex congenital heart disease (CHD) do not develop the skills to feed orally and are discharged home on gastrostomy tube or nasogastric feeds. We aimed to identify risk factors for failure to achieve full oral feeding and evaluate the efficacy of oral motor intervention for increasing the rate of discharge on full oral feeds by performing a prospective study in the neonatal and cardiac intensive care units of a tertiary children's hospital. 23 neonates born at ≥37weeks gestation and diagnosed with single-ventricle physiology requiring a surgical shunt were prospectively enrolled and received oral motor intervention therapy. 40 historical controls were identified. Mean length of stay was 53.7days for the control group and 40.9days for the study group (p=0.668). 13/23 patients who received oral motor intervention therapy (56.5%) and 18/40 (45.0%) controls were on full oral feeds at discharge, a difference of 11.5% (95% CI -13.9% to 37.0%, p=0.378). Diagnosis of hypoplastic left heart syndrome, longer intubation and duration of withholding enteral feeds, and presence of gastroesophageal reflux disease were predictors of poor oral feeding on univariate analysis. Although we did not detect a statistically significant impact of oral motor intervention, we found clinically meaningful differences in hospital length of stay and feeding tube requirement. Further research should be undertaken to evaluate methods for improving oral feeding in these at-risk infants.

    Objective To explore the risk factors of hyperbilirubinemia in late preterm infants. Methods Clinical data of 211 cases of late preterm infants with hyperbilirubinemia and 246 cases of late preterm infants without hyperbilirubinemia were retro-spectively analyzed between 2011 and 2012. The risk factors of hyperbilirubinemia were filtered. Results Twenty-seven cases of late premature infants with hyperbilirubinemia were severe. Hospital stay less than 3 days, birth asphyxia history, small for gestatio-nal age, head hematoma, delivery injury, hypoalbuminemia, polycythemia, infection, hemolytic disease, feeding intolerance, and fe-tal excretion delay were associated with hyperbilirubinemia (P<0.05). Rural origin, pregnancy-induced hypertension syndrome and premature rupture of membrane were also associated with hyperbilirubinemia (P<0.05). Multivariate logistic regression analysis showed the history of birth asphyxia , fetal excretion delay, hypoalbuminemia, pregnancy-induced hypertension syndrome were risk factors of hyperbilirubinemia in late preterm infants (OR=2.35-4.05). Pregnancy-induced hypertension syndrome and hemolytic dis-ease were risk factors of severe hyperbilirubinemia in late preterm infants (OR=5.74, 73.64). Conclusions Neonatal asphyxia, fetal excretion delay, hypoalbuminemia and pregnancy-induced hypertension syndrome are risk factors of hyperbilirubinemia in late pre-term infants. Strengthening the management of pregnancy-induced hypertension syndrome and the treatment of newborn hemolytic disease can reduce the occurrence of severe hyperbilirubinemia in late preterm infants.%目的:探讨晚期早产儿高胆红素血症的危险因素。方法回顾性分析2011年至2012年收治的211例高胆红素血症晚期早产儿和246例非高胆红素血症晚期早产儿的临床资料,分析可能造成晚期早产儿高胆红素血症的危险因素。结果211例高胆红素晚期早产儿中27例为重症,晚期早产儿高胆红素血症

    Macrosomia, defined as a birthweight at least 4000 g, is a public health problem because of its adverse influences on maternal and neonatal outcomes. Studies show that there is an increasing prevalence of macrosomia births in developing countries. However, information on the epidemiology of macrosomia is limited in China. This study aimed to determine the prevalence and geographic variability of macrosomia in China and risk factors that can be targeted for intervention. A hospital-based, cross-sectional survey was conducted in 14 provinces in China, covering a wide range of geographic areas. The medical records of 101,723 singleton term infants born in 39 hospitals during 2011 were reviewed. Multiple logistic regression analysis was used to examine the associations between demographic characteristics and the risk of macrosomia. The total prevalence of macrosomia was 7.3%. The prevalence varied between provinces, ranging from 4.1% to 13.4%. The prevalence of macrosomia in northern China (8.5%) was significantly higher than that in southern China (5.6%). Logistic regression analyses showed that risk of macrosomia was positively associated with maternal age, pre-pregnant body mass index (BMI), gravidity, parity, maternal height, gestational weight gain (GWG), gestational diabetes mellitus (GDM), and male fetal sex. Maternal BMI, gestational week, and GWG were the three risk factors most strongly associated with macrosomia. The prevalence of macrosomia varied dramatically between different areas of China. High pre-pregnancy BMI and GWG represent main modifiable risk factors for macrosomia and need more attention from health care providers. © 2014 John Wiley & Sons Ltd.

    Acute kidney injury (AKI) after pediatric cardiac surgery is associated with high morbidity and mortality. Modifiable risk factors for postoperative AKI including perioperative anesthesia-related parameters were assessed. The authors conducted a single-center, retrospective cohort study of 220 patients (aged 10 days to 19 years) who underwent congenital cardiac surgery between January and December 2012. The incidence of AKI within 7 days postoperatively was determined using the Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Ninety-two patients (41.8%) developed AKI and 18 (8.2%) required renal replacement therapy within the first postoperative week. Among patients who developed AKI, 57 patients (25.9%) were KDIGO stage 1, 27 patients (12.3%) were KDIGO stage 2, and eight patients (3.6%) were KDIGO stage 3. RACHS-1 (Risk-Adjusted classification for Congenital Heart Surgery) category, perioperative transfusion and fluid administration as well as fluid overload were compared between patients with and without AKI. Multivariable logistic regression analyses determined the risk factors for AKI. AKI was associated with longer hospital stay or ICU stay, and frequent sternal wound infections. Younger age (CPB) time (OR, 2.45; 95% CI, 1.24–4.84), and low preoperative hemoglobin (OR, 2.40; 95% CI, 1.07–5.40) were independent risk factors for AKI. Fluid overload was not a significant predictor for AKI. When a variable of hemoglobin concentration increase (>3 g/dl) from preoperative level on POD1 was entered into the multivariable analysis, it was independently associated with postoperative AKI (OR, 6.51; 95% CI, 2.23–19.03 compared with no increase). This association was significant after adjustment with patient demographics, medication history and RACHS-1 category (hemoglobin increase >3g/dl vs. no increase: adjusted OR, 6.94; 95% CI, 2.33–20.69), regardless of different age groups and cyanotic or non-cyanotic heart disease.

    Full Text Available Cryptosporidium epidemiology is poorly understood, but infection is suspected of contributing to childhood malnutrition and diarrhea-related mortality worldwide.A prospective cohort of 108 women and their infants in rural/semi-rural Tanzania were followed from delivery through six months. Cryptosporidium infection was determined in feces using modified Ziehl-Neelsen staining. Breastfeeding/infant feeding practices were queried and anthropometry measured. Maternal Cryptosporidium infection remained high throughout the study (monthly proportion = 44 to 63%. Infection did not differ during lactation or by HIV-serostatus, except that a greater proportion of HIV-positive mothers were infected at Month 1. Infant Cryptosporidium infection remained undetected until Month 2 and uncommon through Month 3 however, by Month 6, 33% of infants were infected. There were no differences in infant infection by HIV-exposure. Overall, exclusive breastfeeding (EBF was limited, but as the proportion of infants exclusively breastfed declined from 32% at Month 1 to 4% at Month 6, infant infection increased from 0% at Month 1 to 33% at Month 6. Maternal Cryptosporidium infection was associated with increased odds of infant infection (unadjusted OR = 3.18, 95% CI 1.01 to 9.99, while maternal hand washing prior to infant feeding was counterintuitively also associated with increased odds of infant infection (adjusted OR = 5.02, 95% CI = 1.11 to 22.78.Both mothers and infants living in this setting suffer a high burden of Cryptosporidium infection, and the timing of first infant infection coincides with changes in breastfeeding practices. It is unknown whether this is due to breastfeeding practices reducing pathogen exposure through avoidance of contaminated food/water consumption; and/or breast milk providing important protective immune factors. Without a Cryptosporidium vaccine, and facing considerable diagnostic challenges and ineffective treatment in

    Background Small for gestational age (SGA) infants are associated with a high rate of oligohydramnios, stillbirth and cesarean delivery. Among SGA patients there is a higher risk of neonatal complications, such as polycythemia, hyperbilirubinemia, and hypothermia. Additionally, the SGA infant is prone to suffer from major neurologic sequelae, as well as cardiovascular system disease, in later life. Proper monitoring and therapy during pregnancy are, therefore, of utmost importance. The present study aimed to investigate the influential and prognostic factors of SGA infants.Methods From January 2001 to June 2007, a total of 55 SGA neonatal infants were included in a study group. All were born at Peking Union Medical College Hospital, with regular formal antenatal examinations. In addition, a total of 122 cases of appropriate for gestational age (AGA) infants were bom at the same time and were registered into a control group. All cases were singleton pregnancies with detailed information of the maternal age, gravidity, parity, maternal height and weight, complications, uterine height and abdominal circumference, results from transabdominal ultrasonography between 32-38 gestational weeks, pregnancy duration, delivery manner, placenta, umbilical cord, and neonatal complications.Results Significant differences were observed in placenta weight and neonatal malformations between the study and control groups. Multivariate analysis revealed increased parity, maternal hyperthyroidism and hyperthyroidism history as risk factors. Fetal abdominal circumferences less than 30 and 32 cm at 32-38 gestational weeks respectively, as determined by ultrasonography, resulted in a Youden index of 0.62.Conclusions SGA infants were associated with a greater risk of smaller placentas and infant malformations. Increased parity, maternal hyperthyroidism, and a hyperthyroid history were risk factors for SGA infants. Fetal abdominal circumference less than 30 cm at 32 gestational weeks and less

    Environmental variables have been explored in studies of the development of young children with motor delays. Linking environmental variables to the International Classification of Functioning, Disability and Health - Children and Youth (ICF-CY), environmental factors (EFs) categories can provide a common language for documenting their contribution to developmental outcomes. This review of studies aimed to (1) link EFs for developmental outcomes in infants with or at risk for motor delays to ICF-CY categories and (2) synthesize the influences of EFs (with ICF-CY linkage) on developmental outcomes. A systematic literature search was performed of multiple databases. After applying selection criteria, environmental variables in 28 articles were linked to ICF-CY categories and underwent qualitative synthesis. Results indicated that physical environmental variables could be linked successfully to ICF-CY EFs categories, but not social environmental variables. Multiple environmental variables were associated with motor and other developmental outcomes. Difficulties in linking social factors to ICF-CY categories indicate that additional EFs codes may need to be considered in the ICF-CY revision processes. The review provides empirical data on relationships between EFs and developmental outcomes in children with or at risk for motor delay.

Two hundred and eighty-eight term infants served as the control group. Logistic regression analysis was used to identify risk factors associated with late preterm birth. The common complications in late preterm infants were investigated. Results Several significant risk factors for late preterm birth were identified by logistic regression analysis: twin pregnancy, gestational diabetes mellitus, eclampsia or preeclampsia, placenta previa, placental abruption and premature rupture of membranes. The duration of hospitalization in late preterm infants was longer than that in term infants. The complications were common in late preterm infants, with a high prevalence of anemia, aspiration pneumonia, hypoglycemia and intracranial hemorrhage. Conclusions The late preterm infants are much more likely to suffer various complications. It is important to reduce the incidence of late preterm births by decreasing perinatal risk factors above mentioned.%目的:探讨晚期早产儿(late preterm infant,LPI)早产相关危险因素及临床常见并发症.方法:对287例LPI临床资料进行回顾性分析,同时随机抽取288例同期住院的足月新生儿作对照,应用logistic回归分析的方法筛选LPI早产的危险因素,并分析其常见临床并发症的发生等情况.结果:Logistic回归显示双胎、妊娠期糖尿病、先兆子癎及子癎、前置胎盘、胎盘早剥及胎膜早破为LPI早产发生的危险因素.LPI住院时间明显长于足月儿,其各系统并发症发生率均较高,其中以贫血、吸人性肺炎、低血糖症、颅内出血等为主.结论:LPI生后易发生多种并发症,应注意密切观察,及时救治.避免围产期异常分娩因素的发生是降低LPI出生的关键.

    The role of bacteria in the causation of sudden infant death syndrome (SIDS) is gaining acceptance. Mainstream research favouring respiratory compromise has failed to provide a plausible pathogenetic mechanism despite many years of investigation and thousands of research papers. Bacterial colonisation of the colon of the human infant is influenced by many factors including age, mode of delivery, diet, environment, and antibiotic exposure. The gut microbiome influences development of the immune system. The gut microflora could be important in protection against the bacteria and/or their toxins purportedly involved in SIDS pathogenesis. The aim was to perform a preliminary investigation of the gut microflora in sudden infant death syndrome (SIDS) compared with live comparison babies. The intestinal contents from 52 SIDS, and 102 faecal samples from age-matched live comparison infants were screened by PCR to target 16s RNA genes of Clostridium innocuum, Cl. Perfringens, Cl. difficile, Bacteroides thetaiotaomicron and Staphylococcus aureus. Gut colonisation of the babies with these bacteria was analysed in relation to age, gender and type of feeding; and for SIDS babies sleeping position. Cl. difficile, Cl. innocuum and B. thetaiotaomicron were significantly associated with SIDS with 25%, 46% and 30% of cases PCR positive for these respective bacteria compared with only 6%, 23% and 8.8% respectively in the comparison group. SIDS babies had dual colonisation by both Cl. perfringens and Cl. difficile significantly more often than comparison babies and also with triple colonisation by Cl. perfringens, Cl. difficile and Cl. innocuum. SIDS babies were more often colonised by S. aureus than comparison babies. In addition, SIDS babies found prone were significantly more likely to be colonised by S. aureus than for other positions recorded (OR = ∞; CI = 2·04 - ∞). No significant differences between breast and bottle-fed SIDS babies was observed in regard to each

Logistic regression analysis: mother pregnancy infection,vaginal delivery,septicemia,mechanical ventilation were independent risk factors for hemorrhagic brain injury,while the birth weight was its protective factor. Mechanical ventilation,septicemia,low carbonated hematic disease were independent risk factors for ischemic cerebral injury,while the prenatal use of cortical hormone and birth weight were its protective factors. Conclusions Therefore premature infant brain injury is a complex outcome of multiple factor interaction. Intrauterine exposure including prenatal mothers suffered from infection, perinatal hypoxia and infection after birth are.risk factors for encephalopathy in premature infants.

    Objective To evaluate the risk factors for intracranial hemorrhage in premature infants. Methods Cochrane Library, PubMed, ScienceDirect, Chinese Academic Literature Main Database, Chinese Science and Technology Periodi-cal Database, Wanfang Periodicals and Dissertation Database were searched for articles published from January 2000 to December 2012 on the risk factors of intracranial hemorrhage in premature infants, with retrospective retrieval and manual retrieval as supplement. RavMan5.2 provided by Cochrane was used for meta-analysis. Fixed-or random-effects models were selected according to the results of heterogeneity test. Results Nine studies were conifrmed to be eligible. Odds ratio (OR) and 95%conifdence interval (CI) of the risk factors were as follows:gestation age≤32 weeks (OR=3.29, 95%CI=2.76-3.91), birth weight≤1 500g (OR=2.68, 95% CI=2.24-3.20), maternal complications (OR=1.59, 95% CI=1.23-2.06), intrauterine distress or birth asphyxia (OR=2.42, 95% CI=2.06-2.84), mechanical ventilation (OR=3.23, 95% CI=2.55-4.09), metabolic acidosis (OR=2.88, 95%CI=2.04-4.05), use of high concentration of oxygen (OR=2.98, 95%CI=1.63-5.44), prenatal use of dexametha-sone (OR=0.69, 95%CI=0.55-0.86), respiratory distress syndrome (OR=1.57, 95%CI=1.04-2.39). Those differences were all statistically signiifcant. There was no difference in caesarean section (OR=0.99, 95%CI=0.84-1.17), multiparity (OR=1.05, 95%CI=0.79-1.40) and gender (OR=1.25, 95%CI=0.97-1.59). Conclusions The risk factors for intracranial hemorrhage in premature infants are gestation age≤32 weeks, birth weight≤1 500 g, maternal complications, intrauterine distress or birth asphyxia, mechanical ventilation, metabolic acidosis, use of high concentration of oxygen, respiratory distress syndrome, but prenatal use of dexamethasone can reduce the incidence of intracranial hemorrhage in premature infants.%目的综合评价早产儿颅内出血的危险因素。方法检索Cochrane图书馆、PubMed

    Full Text Available Small for gestational age (SGA is not only a major indicator of perinatal mortality and morbidity, but also the morbidity risks in later in life. We aim to estimate the association between the birth of SGA infants and the risk factors and adverse perinatal outcomes among twenty-nine countries in Africa, Latin America, the Middle East and Asia in 359 health facilities in 2010-11.We analysed facility-based, cross-sectional data from the WHO Multi-country Survey on Maternal and Newborn Health. We constructed multilevel logistic regression models with random effects for facilities and countries to estimate the risk factors for SGA infants using country-specific birthweight reference standards in preterm and term delivery, and SGA's association with adverse perinatal outcomes. We compared the risks and adverse perinatal outcomes with appropriate for gestational age (AGA infants categorized by preterm and term delivery.A total of 295,829 singleton infants delivered were analysed. The overall prevalence of SGA was highest in Cambodia (18.8%, Nepal (17.9%, the Occupied Palestinian Territory (16.1%, and Japan (16.0%, while the lowest was observed in Afghanistan (4.8%, Uganda (6.6% and Thailand (9.7%. The risk of preterm SGA infants was significantly higher among nulliparous mothers and mothers with chronic hypertension and preeclampsia/eclampsia (aOR: 2.89; 95% CI: 2.55-3.28 compared with AGA infants. Higher risks of term SGA were observed among sociodemographic factors and women with preeclampsia/eclampsia, anaemia and other medical conditions. Multiparity (> = 3 (AOR: 0.88; 95% CI: 0.83-0.92 was a protective factor for term SGA. The risk of perinatal mortality was significantly higher in preterm SGA deliveries in low to high HDI countries.Preterm SGA is associated with medical conditions related to preeclampsia, but not with sociodemographic status. Term SGA is associated with sociodemographic status and various medical conditions.

    Objective To investigate the health states and related risk factors of the high - risk infants' parents ( HRI) , so as to provide the basis for early interventions. Methods Through cross - sectional investigation method, from 11 november,2010 to 31 decem-ber,subjects were selected from HRI hospital clinic in Cixi, Yuyao, Zhenhai, Jiangbei four counties and stratified at random by economic conditions. Informed consents were obtained from subjects. All subjects(299 parents) were 18 -45 years old, with normal intelligence, willing to cooperate with the appropriate psychological tests, with risk factors for perinatal brain injury in infants ( high - risk infants) . With no risk factors during the same period, single - child birth healthy infants' parents of 157 were collected as the normal control group. At 1 month postpartum, Physical Symptom Scale (PHQ - 15) , Depression Scale (PHQ -9) , and Generalized Anxiety Scale (GAD -7) and other related questions were investigated. Related risk factors of the health states of HRI were identified through single factor analysis and logistic regression analysis, etc. Results Positive rate of mother's health problem in HRI group was 40. 1% , in normal control group was 24. 8% . Positive rate of father's health problem in HRI group was 26. 4% , in normal control group was 12. 1% . The differences had statistical significance. By single factor analysis, the main factors of health problems in HRI mothers were related to 12 factors in eluding family type, mother's religious beliefs,mother's health status, father's health status, infant's gestational age, birth weight and. And 9 factors inoluding family type, mother's monthly income, paternal age were related to HRI fathers' health problem. By multivariate logistic regression analysis, family type, mother's religious beliefs, mother's long-term drug use, mother's history of pregnancy and delivery, father's health status, family relationship, infant's birth weight may be the main health

    Sudden infant death syndrome (SIDS) has been most recently defined as the sudden unexpected death of an infant less than one year of age, with onset of the fatal episode apparently occurring during sleep, that remains unexplained after a thorough investigation, including the performance of a complete autopsy and a review of the circumstances of death and clinical history. Despite the success of several prevention campaigns, SIDS remains a leading cause of infant mortality. In 1994, a 'triple risk model' for SIDS was proposed that described SIDS as an event that results from the intersection of three factors: a vulnerable infant; a critical development period in homeostatic control (age related); and an exogenous stressor. The association between pacifier (dummy) use and reduced incidence of SIDS has been shown in epidemiological studies since the early 1990s. Pacifier use, given its low cost, might be a cost-effective intervention for SIDS prevention if it is confirmed effective in randomised controlled trials. To determine whether the use of pacifiers during sleep versus no pacifier during sleep reduces the risk of SIDS. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 2), MEDLINE via PubMed, Embase, and CINAHL to 16 March 2016. We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. Published and unpublished controlled trials using random and quasi-random allocations of infants born at term and at preterm (less than 37 weeks' gestation) or with low birth weight (searches. We found no eligible studies. We identified no randomised controlled trials examining infant pacifiers for reduction in risk of SIDS. We found no randomised control trial evidence on which to support or refute the use of pacifiers for the prevention of SIDS.

    晚期早产儿又称近足月儿.该胎龄的早产儿外表接近成熟,由于器官发育不成熟,比足月儿存在更大发病风险,脑损伤与足月儿相比发病风险明显增加,脑性瘫痪的发病率增加3倍,生长发育/心理发育迟缓也有明显增多,这主要与晚期早产儿脑发育不成熟有关.晚期早产儿其他系统的常见病发生率也比较高,如窒息、低血糖、高胆红素血症、呼吸窘迫综合征、喂养困难等,这些疾病也可不同程度地影响脑发育,造成脑损伤.%Late preterm is labeled near term. As developmental immaturity, there was higher morbidity in late preterm infants compared with term infants. Especially brain injury, a 3-fold increased risk of cerebralpalsy and significantly higher rates of developmental delay and mental retardation for late preterm infants compared with term infants. In addition, a higher rates of neonatal complications had been documented on late preterm infants. These problems included apnea, hypoglycemia, hyperbilirubinemia, respiratory distress syndome, and poor feeding. It was known that long-term impact of these diseases will result in brain injury.

    The estimated HIV prevalence among pregnant women in Ethiopia is 1.2 percent and unfortunately one of every 3 children born to these women gets infected with HIV. Elimination of these mother-to-child transmissions (MTCT) of HIV is possible through HIV testing during pregnancy and taking antiretroviral medications. However, only 24 percent of the pregnant women living with HIV have yet received the medication needed to prevent the transmission of HIV. Hence, there exists a concern that the rate of HIV infection among infants born to HIV positive mothers is increasing. This study assessed the prevalence of HIV infection and associated factors among infants born to women living with HIV, in South Gondar zone, Amhara region, Ethiopia. Facility based document review was conducted upon 434 charts. The study participants were HIV exposed infants enrolled from January to December 2012. The data were reviewed from all the 17 health facilities which were providing PMTCT services in the zone. The study included 434 HIV exposed infants having an HIV Deoxyribonucleic Acid (DNA) Polymerase Chain Reaction (PCR) test result. The data were collected using structured data extraction tool. Binary logistic regression analysis was employed to assess the putative association of independent variables with the outcome variable. Significance was taken at a P valueinstrumental to curb the devastating consequences of HIV on pregnant women and their newborns.

    Full Text Available This descriptive-correlational study aimed to detect risks for child developmental problems in the first four years of age, to identify the protective resources in the familiar environment, and to verify the best predictive variables of the development at risk. The non-clinical sample was composed by 120 children registered in a Family Health Program. The assessment instruments for global development, expressive language and familiar environment were used. The logistic regression analysis indicated that the lower the father's educational level, the higher the risk for developmental problems. Both the history of low nutritional state at six months of age and the psychosocial risk in the family environment increased the chances of having expressive language problems. It is concluded that screening tests of risk for developmental problems and the analysis of the psychosocial factors in the familiar context should be considered as preventive intervention procedure in the Family Health Programs.El estudio descriptivo-correlacional objetiva detectar riesgos para problemas del desarrollo del niño en los cuatro primeros años, identificar recursos protectores en el ambiente familiar, verificar las mejores variables antedichas del desarrollo en riesgo, en una muestra no-clínica de 120 niños registrados en un Programa de Salud de la Familia. Fueron utilizados instrumentos de evaluación del desarrollo global, lenguaje expresivo del niño y ambiente familiar. El análisis de regresión logística indicó que cuanto menor escolaridad del padre, mayor chance de riesgo para problemas de desarrollo. El histórico del estado nutricional debajo de lo normal a los seis meses de edad y el riesgo psicosocial en el ambiente familiar aumentaba la probabilidad de problemas de lenguaje expresivo.

    A large social science and public health literature addresses infant sleep safety, with implications for infant mortality in the context of accidental deaths and Sudden Infant Death Syndrome (SIDS). As part of risk reduction campaigns in the USA, parents are encouraged to place infants supine and to alter infant bedding and elements of the sleep environment, and are discouraged from allowing infants to sleep unsupervised, from bed-sharing either at all or under specific circumstances, or from sofa-sharing. These recommendations are based on findings from large-scale epidemiological studies that generate odds ratios or relative risk statistics for various practices; however, detailed behavioural data on nighttime parenting and infant sleep environments are limited. To address this issue, this paper presents and discusses the implications of four case studies based on overnight observations conducted with first-time mothers and their four-month old infants. These case studies were collected at the Mother-Baby Behavioral Sleep Lab at the University of Notre Dame USA between September 2002 and June 2004. Each case study provides a detailed description based on video analysis of sleep-related risks observed while mother-infant dyads spent the night in a sleep lab. The case studies provide examples of mothers engaged in the strategic management of nighttime parenting for whom sleep-related risks to infants arose as a result of these strategies. Although risk reduction guidelines focus on eliminating potentially risky infant sleep practices as if the probability of death from each were equal, the majority of instances in which these occur are unlikely to result in infant mortality. Therefore, we hypothesise that mothers assess potential costs and benefits within margins of risk which are not acknowledged by risk-reduction campaigns. Exploring why mothers might choose to manage sleep and nighttime parenting in ways that appear to increase potential risks to infants may

    Childhood obesity is associated with a number of modifiable risk factors that can be identified during infancy or earlier. In the UK, health visitors advise parents about infant feeding, but little is known about their role in obesity prevention. The aim of this study was to investigate the beliefs and current practices of UK health visitors in relation to recognising and intervening with infants at risk of developing obesity. Thirty members of the health visiting team were interviewed. The interviews were audio-recorded and transcribed verbatim. Thematic analysis was applied using an interpretative, inductive approach. Health visitors were aware of some of the modifiable risk factors for childhood obesity such as infant feeding practices. They felt they had a role in advising parents about diet but did not formally identify and/or intervene with larger infants. Infant overweight was considered a sensitive issue that was difficult to raise with parents. They believed some parents preferred larger infants and were unaware that their feeding practices might be contributing to obesity risk. A need for training and guidance was identified together with strategies to overcome system barriers. Health visitors do not currently target parents of infants at risk of obesity largely because they do not perceive they have appropriate guidance and skills to enable them to do so. There is an urgent need for tools and training to enable all health care professionals to recognise and manage infants at risk of developing obesity without creating a sense of blame.

    Objective To explore the risk factors of early respiratory complications in late preterm infants. Methods A total of 112 late preterm infants diagnosed with early respiratory complications were collected as the re-search group. At the same time, 112 late preterm infants without early respiratory complications were selected as the con-trol group. The clinical data was analyzed between the two groups in order to identify the risk factors of early respiratory complications in late preterm infants. Results Single factor analysis showed that the related factors of early respiratory complications in late preterm infants included the pregnancy-induced hypertension syndrome, placenta previa, placental abruption, maternal fever during the late pregnancy, premature rupture of membranes, contamination of amniotic fluid, fetal intrauterine distress, asphyxia, small for gestational age infant, cesarean delivery, incidence of multiple pregnancy and neonatal sepsis (P<0.05). Multivariate logistic regression analysis of the above indexes revealed that maternal fever during the late pregnancy, premature rupture of membranes, fetal intrauterine distress, cesarean delivery, incidence of multiple pregnancy, asphysia, and neonatal sepsis were the risk factors for early respiratory complications in late preterm infants (P<0.05), which have early warning function. Conclusion It is important to focus the risk factors for effective monitoring and follow-up, which could provide timely reasonable intervention for neonates and reduce the incidence of early respiratory complications in late preterm infants and the neonatal mortality.%目的 探讨晚期早产儿发生近期呼吸系统并发症的危险因素.方法 选取2011年1月至2014年12月我院收治的112例发生了近期呼吸系统疾病的晚期早产儿为观察组,随机选取同期收治的112例未发生此类疾病的晚期早产儿为对照组,分别对两组患儿的临床资料进行分析,筛选出晚期早产儿发生

    of SGA was 13.1%. Even after adjusting for possible confounding variables, the odds ratio for SGA among those infants whose family income was ³10 minimum wage. An antenatal care of low quality was associated with an odds ratio of 3.28 (95% CI, 1.09-9.91 for SGA. Short maternal stature and maternal smoking during pregnancy were also associated with SGA births. CONCLUSIONS: Low socioeconomic status, maternal smoking during pregnancy, maternal height and an antenatal care of low quality are the main risk factors for SGA births.

    晚期早产儿,为胎龄介于34+ (0-7)至36 +(6-7)孕周出生的新生儿.虽然晚期早产儿的外观发育特点与足月儿相近,但因其各系统尚未完全发育成熟,导致其并发症发生率与病死率均高于足月儿.人们逐渐认识到,要降低晚期早产率必须研究其发生原因并进行本质干预.目前发现母亲孕期某些高危因素与晚期早产的发生有着密切联系,如妊娠期高血压、妊娠期贫血、胎膜早破等,并且这些母源性因素将对晚期早产儿出生后的生长发育有重要影响.%Late-preterm infants are the neonates whose gestational ages are from 34+(0-7) to 36+(67)weeks.Although they look like term infants,their organs are immature.So the incidence of complication and mortality in late-preterm infants are higher than those of term infants.Now people have gradually realized that we could reduce the incidence of late-premature birth by exploring the pathogenesis of late-premature birth and trying to intervene it.People also have found that some maternal risk factors during pregnancy lead to latepreterm birth easily,such as pregnancy hypertension,pregnancy anemia,premature rupture of membranes,etc.These factors have significant impacts on the growth and development of late-preterm infants after birth.This paper is to review the progress of some maternal factors of late-preterm infants and their short and long term risks.

    The authors hypothesized that among extremely preterm infants, elevated concentrations of inflammation-related proteins in neonatal blood are associated with cerebral palsy at 24 months. In 939 infants born before 28 weeks gestation, the authors measured blood concentrations of 25 proteins on postnatal days 1, 7, and 14 and evaluated associations between elevated protein concentrations and cerebral palsy diagnosis. Protein elevations within 3 days of birth were not associated with cerebral palsy. Elevations of tumor necrosis factor-α, tumor necrosis factor-α-receptor-1, interleukin-8, and intercellular adhesion molecule-1 on at least 2 days were associated with diparesis. Recurrent-persistent elevations of interleukin-6, E-selectin, or insulin-like growth factor binding protein-1 were associated with hemiparesis. Diparesis and hemiparesis were more likely among infants who had at least 4 of 9 protein elevations that previously have been associated with cognitive impairment and microcephaly. Repeated elevations of inflammation-related proteins during the first 2 postnatal weeks are associated with increased risk of cerebral palsy.

    Full Text Available BACKGROUND: Delivery of a small for gestational age (SGA infant has been associated with increased maternal risk of ischemic heart disease (IHD. It is uncertain whether giving birth to SGA infant is a specific determinant of later IHD, independent of other risk factors, or a marker of general poor health. The purpose of this study was to investigate the association between delivery of a SGA infant and maternal risk for IHD in relation to traditional IHD risk factors. METHODS AND FINDINGS: Risk of maternal IHD was evaluated in a population based cross-sectional study of 6,608 women with a prior live term birth who participated in the National Health and Nutrition Examination Survey (1999-2006, a probability sample of the U.S. population. Sequence of events was determined from age at last live birth and at diagnosis of IHD. Delivery of a SGA infant is strongly associated with greater maternal risk for IHD (age adjusted OR; 95% CI: 1.8; 1.2, 2.9; p = 0.012. The association was independent of the family history of IHD, stroke, hypertension and diabetes (family history-adjusted OR; 95% CI: 1.9; 1.2, 3.0; p = 0.011 as well as other risk factors for IHD (risk factor-adjusted OR; 95% CI: 1.7; 1.1, 2.7; p = 0.025. Delivery of a SGA infant was associated with earlier onset of IHD and preceded it by a median of 30 (interquartile range: 20, 36 years. CONCLUSIONS: Giving birth to a SGA infant is strongly and independently associated with IHD and a potential risk factor that precedes IHD by decades. A pregnancy that produces a SGA infant may induce long-term cardiovascular changes that increase risk for IHD.

  15. Infant feeding and obesity risk in the child.

    2012-07-01

    Early nutrition in infancy may influence later child health outcomes including overweight through 'programming'. Systematic reviews suggest that breastfeeding is associated with a modest reduction in the risk of later overweight and obesity. This commentary explores some of these mechanisms behind this association. Generally breastfed infants are leaner than artificially (formula)-fed infants and behavioural and hormonal mechanisms may explain this difference. The theory is that a high nutrient diet in infancy adversely programs the principal components of the metabolic syndrome in the child (body mass index, blood pressure and blood lipids) by promoting growth acceleration, whereas slower growth benefits later cardiovascular disease and its risk factors. Artificial-feeding stimulates a higher postnatal growth velocity with the adiposity rebound occurring earlier in those children who have greater fatness later, whereas breastfeeding has been shown to promote slower growth. The adverse long-term effects of early growth acceleration emerge as fundamental in later overweight and obesity. The higher protein content of artificial baby milk compared to the lower protein content in breastmilk is responsible for the increased growth rate and adiposity during the influential period of infancy of formula-fed infants. Breastfeeding, on the other hand, has a protective effect on child overweight and obesity by inducing lower plasma insulin levels, thereby decreasing fat storage and preventing excessive early adipocyte development. Plausible biological mechanisms underlying the protective effect of breastfeeding against obesity are based on the unique composition of human milk and the metabolic and physiological responses to human milk.

Rev. Hosp. Clín. Fac. Med. S. Paulo, 53(6): 303-310, 1998. The objective of this study was to verify the immunological behavior of the newborn infant in front of an infection. We studied 60 newborn infants that had risk factors for early onset sepsis (premature rupture membranes, clinic amnionitis or tract urinary infection) from de immunological and infection point of view. They were classified into three gestational age groups: or = 37 weeks. Sepsis diagnosis was done through clinical and laboratorial data and we also included the followings exams: Immunological types (IgG, IgM, IgA) and total complement (CH50) obtained from the newborn at birth and on the fifth day of life. We could verify that 15 newborns (25%) presented early sepsis. There was a statistical association between perinatal asfixia and infection in the group with gestational age < 34 weeks and this same group presented statistical association between infection and death. The serical levels of IgG and CH50 were directly related to the gestational age and there were significant statistical differences between levels of IgG, IgM and total Complement between infected and not infected newborns within the same group os gestional age. We observed that the infection was associated to low levels of IgG and CH50, at birth and on the fifth day, mainly in the group of infected newborns with gestional age < 34 weeks, being this group, therefore, the one that would mostly benefit from an immunological support in front of and infection.

    1998-02-01

    This study was carried out to determine whether bedding used by infants, who are at either high or low risk for sudden infant death syndrome (SIDS), differs in physical properties favoring rebreathing of exhaled gases. We compared softness and limitation of carbon dioxide dispersal by bedding, using a mechanical model. A questionnaire was used to describe sociodemographic risk factors and sleep practices; bedding was studied in homes with a model positioned where each infant was found sleeping that morning. The groups differed with respect to five sociodemographic risk factors (p values all < or = 0.0001). In addition, infants at higher risk were more likely to have been placed to sleep prone (46%, p = 0.02) by parents who were less likely to be aware of the risk associated with the prone position (62% aware, p = 0.005). Infants at higher risk had softer bedding (p < 0.0001, 54.1+/-17.2 cm2 vs 33.7+/-7.7 cm2 in contact with model), which caused more limitation of carbon dioxide dispersal (p = 0.008; CO2 retained, 0.60%+/-0.15% vs 0.34%+/-0.05%). A series of infants who are at high risk for SIDS because of sociodemographic factors more often sleep on bedding that has physical properties favoring rebreathing, and their parents are less often aware of the risk associated with prone sleeping.

    Full Text Available Objective: Infant mortality rate is one of the most expressive indicators of development in all countries. The aim of this study was to determine the cause of infant mortality and risk factors in rural areas of Birjand in Iran. Methods: This population based case-control study covered 156 infants who died when aged less than one-year in health houses of Birjand between January 2004 and December 2005. For each case, two controls were selected matching one-to-one to the case considering variables of residency and their date of birth. The data was collected through interview with mothers and reviewing infants files in health houses. Findings: 57.7 percent of deaths in under one year old infants happened during the first month of their lives. The most important causes of death in neonates were prematurity and low birth weight (44.4% later gastroenteritis (30.3%. In addition, the study showed that 9.6 percent of infants had died because of narcotic toxicosis. Moreover, the study showed a significant relationship between infant mortality and parents level of education, mothers addiction, age of mother in the first pregnancy, prematurity, low birth weight, type of delivery and exclusive breast feeding. Conclusion: Special attention to infantile period and special care for infants born to at-risk mothers, as well as providing special health education can cause a dramatic reduction in infants mortality rate.

    Full Text Available OBJECTIVE: To analyze whether previously identified risk factors for sudden death syndrome have a significant impact in a developing country. METHODS: Retrospective longitudinal case-control study carried out in Porto Alegre, Southern Brazil. Cases (N=39 were infants born between 1996 and 2000 who died suddenly and unexpectedly at home during sleep and were diagnosed with sudden death syndrome. Controls (N=117 were infants matched by age and sex who died in hospitals due to other conditions. Data were collected from postmortem examination records and questionnaires answers. A conditional logistic model was used to identify factors associated with the outcome. RESULTS: Mean age at death of cases was 3.2 months. The frequencies of infants regarding gestational age, breastfeeding and regular medical visits were similar in both groups. Sleeping position for most cases and controls was the lateral one. Supine sleeping position was found for few infants in both groups. Maternal variables, age below 20 years (OR=2, 95% CI: 1.1; 5.1 and smoking of more than 10 cigarettes per day during pregnancy (OR=3, 95% CI: 1.3; 6.4, significantly increased the risk for the syndrome. Socioeconomic characteristics were similar in both groups and did not affect risk. CONCLUSIONS: Infant-maternal and socioeconomic profiles of cases in a developing country closely resembled the profile described in the literature, and risk factors were similar as well. However, individual characteristics were identified as risks in the population studied, such as smoking during pregnancy and maternal age below 20 years.OBJETIVO: Analisar se fatores de risco previamente identificados para a síndrome da morte súbita do lactente têm impacto significativo em um país em desenvolvimento.

    Great progress has been made in understanding the pathogenesis, treatment, and transmission of HIV and the factors influencing the risk of mother-to-child transmission (MTCT). Many questions regarding the molecular evolution and genetic diversity of HIV in the context of MTCT remain unanswered. Further research to identify the selective factors governing which variants are transmitted, how the compartmentalization of HIV in different cells and tissues contributes to transmission, and the influence of host immunity, viral diversity, and recombination on MTCT may provide insight into new prevention strategies and the development of an effective HIV vaccine.

  15. Dietary factors and the risk for acute infant leukemia: evaluating the effects of cocoa-derived flavanols on DNA topoisomerase activity.

    There is cumulative strong evidence that diets rich in flavanols can provide certain positive health benefits, particularly with respect to the cardiovascular system. Consequently, it has been suggested that increasing one's dietary intake of flavanols may be of benefit. Complicating this idea, there are reports that high intakes of certain flavonoids during pregnancy are associated with an increased risk for acute infant leukemia due to a poison effect of select polyphenolic compounds on DNA topoisomerase (topo) II activity that promotes aberrant chromosomal translocations. In the current study, we characterized the effects of select flavanols (epicatechin and catechin monomers), and select flavanol dimers and longer oligomers, on topo II activity, and on cellular toxicity in vitro. In contrast to the chemotherapeutic drug etoposide (VP16) and the flavonol quercetin, which strongly inhibited topo II activity and increased the formation of cleavage complexes demonstrating a poison effect, the flavanols epicatechin and catechin had little effect on topo II enzyme activity. Accordingly, several fold greater concentrations of the flavanols were required to achieve cellular toxicity similar to that of quercetin and VP16 in cultures of myeloid and lymphoid cells. Low cellular toxicity and limited topo II inhibition were also observed with a procyanidin-rich cocoa extract. Of all the flavanols tested, the dimers (B2, B5 and a mix of both) exerted the greatest inhibition of topo II and inhibited cellular proliferation rates at concentrations similar to quercetin. However, in contrast to quercetin, the dimers did not function as topo II poisons. Collectively, our in vitro data show that cocoa-derived flavanols have limited effects on topo II activity and cellular proliferation in cancer cell lines. We predict that these compounds are likely to have limited leukemogenic potential at physiological concentrations.

In this study we present the main findings of these 15 subjects. In all infants multifactor antecedents were detected. The most frequent risk factors were prematurity and severe asphyxia; however placenta disorders, sepsis, and hyperbilirubinemia were also frequent. In all infants MRI direct or secondary features of periventricular leukomalacia were observed. Followup of all infants showed moderate to severe neurodevelopmental delay as well as cerebral palsy. It is concluded that prenatal and perinatal risk factors for brain damage are very important antecedents that should be taken into account to follow up those infants from an early age in order to detect and treat as early as possible an epileptic encephalopathy.

    1996-01-01

    Full Text Available A previously calculated predictive model for health risk selects infants who suffer 4-5 times more morbidity than their unselected peers. Preliminary results suggested that this risk is related to maternal neurotic symptomatology. To evaluate this hypothesis, 52 consecutive mothers whose infants had a positive predictive score (Group 1 and 52 in whom this was negative (Group 2 were evaluated by means of Goldberg's General Health Questionnaire (GHQ - 30. A total of 41.9% and 20.5% of the mothers in Groups 1 and 2, respectively, scored above 11 points in GHQ-30, established as the cut off point. It is concluded that among poor urban families in Santiago mothers of infants with high risk of persistent diarrhoea have increased frequency of detectable neurotic symptoms. New programs aimed at this type of infant should include psychological support for their mothers.

    In very low birth weight (VLBW) infants, obstructive bronchitis is a frequent cause of hospital re-admission. For VLBW infants, early vaccinations starting at 2 months after birth have been recommended. To analyze risk factors for bronchitis during the first year after discharge and the effects of in-hospital standard vaccination (hexavalent/pneumococci) and/or RSV immunoprophylaxis with palivizumab. A standardized questionnaire was sent to the parents of VLBW infants 7 month after discharge. The reported episodes of bronchitis were correlated with clinically recorded parameters including risk factors for pulmonary morbidity. The effects of in-hospital vaccination were assessed in a subgroup discharged after day 60. A sample of 1 967 responses of infants born 2009-2011 was analyzed. Risk factors for bronchitis were male gender and older siblings. 24% of the population had episodes of bronchitis. In the subgroup discharged after day 60, episodes of bronchitis were reported for 31% of infants who were not vaccinated in-hospital. A significant reduction of the bronchitis rate was found in infants who received palivizumab±standard vaccination (17% bronchitis, p=0.003). Interestingly, in-hospital standard vaccination without RSV immunoprophylaxis was protective (20% bronchitis; p=0.037) as well. Non-vaccinated male VLBW infants with older siblings are at increased risk for bronchitis during the first year after discharge. Vaccination according to schedule seems to have protective effects, while underlying mechanisms are unknown. The rate of timely vaccination in preterm infants should be increased. © Georg Thieme Verlag KG Stuttgart · New York.

    Previous breastfeeding experience has been associated with subsequent infant feeding practices. However, few longitudinal studies have investigated formula-only feeding patterns or the full range of potentially associated characteristics. This study aimed to determine the recurrence of infant feeding practices and maternal, birthing, and infant characteristics associated with recurrent formula-only feeding and changes between exclusive breastfeeding and formula-only feeding across subsequent births. We conducted a population-based record-linkage study of 317 027 mothers, with a term singleton live-birth in 2007-2011, New South Wales, Australia. Infant feeding patterns were described using sequential birth pairs. For mothers with a first and second birth, robust Poisson regression was used to investigate the association between maternal, birthing, and infant characteristics and infant feeding patterns. Combined relative risks (RRs) were calculated for selected maternal characteristics. Across 69 994 sequential birth pairs, the recurrence rate of formula-only feeding was 71%, and 92% for exclusive breastfeeding. Maternal characteristics breastfeeding to formula-only feeding (RR, 9.0; 95% CI, 7.4-10.7), and being less likely to change from formula-only feeding to exclusive breastfeeding (RR, 0.47; 95% CI, 0.38-0.59). Infant feeding practices were strongly recurrent, highlighting the importance of successful breastfeeding for first-time mothers. Additional support for young mothers from disadvantaged backgrounds accounting for infant feeding history, experiences, and common barriers could improve recurrent exclusive breastfeeding and positively affect infant and maternal health.

    Science.gov (United States)

    Wennergren, Göran

    The Swedish National Board of Health and Welfare has presented new advice to reduce the risk of Sudden Infant Death Syndrome, SIDS, supplemented with factual material for health personnel. The advice state: 1) The infant should sleep on its back, 2) parents should refrain from nicotine, 3) the infant’s face should be kept free, overheating avoided and movements not restrained, 4) the safest place to sleep for an infant under three months is in its own cot, 5) breast-feed if possible, and 6) pacifier (dummy) can be used when the infant is going to sleep. Apparent life-threatening events in the maternity ward are discussed. In early breast-feeding attempts, it should be checked that breathing is free to avoid suffocation accidents. The best hypothesis of SIDS pathogenesis seems to be offered by the triple risk model, suggesting that an interaction of different risk factors leads to SIDS: 1) a critical developmental period, 2) a vulnerable infant and 3) an exogenous stressor (extrinsic risk factor).

    [Objective] To investigate the relationship between perinatal risk factors and early neonatal death among very low birth weight (VLBW) infants. [Methods] A retrospective cohort of 143 VLBW infants admitted to NICU was studied. The dependent variable was the outcome, either survival or death at 7 days of life. The independent variables were assigned into three levels: distal, intermediate and proximal according to hierarchical model. All variables were subjected to univariate analysis and multivariate logistic regression. [Results] Early neonatal mortality was 13. 29% (19/143) in VLBW infants. After the adjustment of variables through multivariate Logistic regression it showed that infants born to mother with cord prolapse had higher risk exposure for early death than those of mother without cord prolapse in the distal level (AOR:8. 69;95%C/:1. 128~67. 002). At the intermediate level,infants with gestational age (GAX28 weeks and 5-min Apgar scores<7 had higher odds of early death than those of GA≥28 weeks and 5-min Apgar scores≥7 (AOR: 11. 47, 13. 55;95%CJ:2. 066~63. 712,3. 156 - 58. 221 respectively). At the proximal level, infants with intracranial hemorrhage (ICH) had higher risk of early death than those without ICH (AORS4. 56,95%C7:1. 088 - 19. 170). [Conclusions] The early neonatal mortality among VLBW infants is still high and continues to be a significant public health problem. Asphyxia at birth is the highest risk factor of early neonatal death. Reducing birth asphyxia through enhancing obstetric quality and strengthening cooperation between obstetric and neonatology department is still the key to decrease early neonatal death of VLBW infants.%[目的]探讨极低出生体重(very low birth weight,VLBW)儿早期死亡的围生期高危因素.

    The best screening method for developmental dysplasia of the hip is controversial. Ultrasonography is sensitive, but cost-effectiveness may limit its use. This study assessed whether ultrasound screening would increase in effectiveness if targeted toward infants with established risk factors for developmental dysplasia of the hip and normal findings on physical examination. All ultrasound scans performed at the authors' institution from January 2007 through January 2011 to screen for developmental dysplasia of the hip were reviewed. Infants with risk factors for developmental dysplasia of the hip and normal findings on physical examination by orthopedic faculty or a pediatrician were selected. Of the 530 cases that were reviewed, 217 had risk factors for developmental dysplasia of the hip and normal findings on physical examination. Mean age of the 217 selected patients was 6.9 weeks. Of the patients, 83% were female, 77% had breech presentation, 30% were firstborn children, 13% had intrauterine packaging abnormalities, and 3% had a family history of developmental dysplasia of the hip. Of the 217 infants, 44 had 1 risk factor, 121 had 2 risk factors, 46 had 3 risk factors, and 6 had 4 risk factors. Dynamic ultrasound evaluation showed instability in 17 patients, for a 7.8% incidence of developmental dysplasia of the hip. All 17 patients were treated with a Pavlik harness. The results suggested that selective ultrasound screening may be effective in infants with risk factors and normal findings on physical examination. Selective ultrasound screening changed treatment management in almost 8% of patients and clinical follow-up in 6.5%. Analysis of the cost-effectiveness of screening is needed.

    BACKGROUND AND AIM: Many preterm infants are not capable of exclusive breastfeeding from birth. To guide mothers in breastfeeding, it is important to know when preterm infants can initiate breastfeeding and progress. The aim was to analyse postmenstrual age (PMA) at breastfeeding milestones...... in different preterm gestational age (GA) groups, to describe rates of breastfeeding duration at pre-defined times, as well as analyse factors associated with PMA at the establishment of exclusive breastfeeding. METHODS: The study was part of a prospective survey of a national Danish cohort of preterm infants...... based on questionnaires and structured telephone interviews, including 1,221 mothers and their 1,488 preterm infants with GA of 24-36 weeks. RESULTS: Of the preterm infants, 99% initiated breastfeeding and 68% were discharged exclusively breastfed. Breastfeeding milestones were generally reached...

    In order to evaluate the surfactant maturation of the neonate, tracheal aspirates were analyzed in 84 newborn infants with 12h of birth. Using 2-dimensional thin-layer chromatography, 9 different phospholipids were identified. Dynamic surface tension measurements were performed with a modified Wilhelmy balance. Five different groups of infants with typical phospholipid patterns were characterized: i.e., 1. Normal term newborn. 2. RDS in the preterm infant. 3. Acceleration of lung maturity in preterm infants without RDS. 4. Retardation in term infants with RDS. 5. Therapeutic induction of pulmonary maturity in preterm infants following maternal glucocorticoid administration. Mature lung effluent contains high concentrations of phosphatidylcholine (PC) and phsophatidylglycerol (PG). In infants with RDS, PC is low and PG absent. Accelerated lung maturity was observed after chronic prenatal stress, such as prolonged rupture of the membranes, chronic vaginal bleeding, and maternal hepatitis or drug addiction. Retardation of pulmonary maturity was seen in infants with alpha-1-AT-deficiency, maternal diabetes and maternal hypothyroidism. Administration of methylprednisolone to the mother 24 h to 72h before birth induced both the synthesis of PC and PG in the preterm infants, resulting in an almost full-term phospholipid pattern as early as 31 weeks of gestation. The significance of these factors on the pathogenesis of RDS is discussed.

    Postnatal maternal depressive symptoms are consistently associated with impairments in maternal attunement (i.e., maternal responsiveness and bonding). There is a growing body of literature examining the impact of maternal cognitive factors (e.g., rumination) on maternal attunement and mood. However, little research has examined the role of infant temperament and maternal social support in this relationship. This study investigated the hypothesis that rumination would mediate (1) the relationship between depressive symptoms and attunement and (2) the relationship between social support and attunement. We further predicted that infant temperament would moderate these relationships, such that rumination would demonstrate mediating effects on attunement when infant difficult temperament was high, but not low. Two hundred and three mothers completed measures on rumination, depressive symptoms, attunement, perceived social support and infant temperament. Rumination mediated the effect of postnatal maternal depressive mood on maternal self-reported responsiveness to the infant when infants were low, but not high, in negative temperament. When infants had higher negative temperament, there were direct relationships between maternal depressive symptoms, social support and maternal self-reported responsiveness to the infant. This study is limited by its cross-sectional and correlational nature and the use of self-report measures to assess a mother's awareness of her infant needs and behaviours, rather than observational measures of maternal sensitivity. These findings suggest potentially different pathways to poor maternal responsiveness than those expected and provide new evidence about the contexts in which maternal cognitive factors, such as rumination, may impact on the mother-infant relationship.

    Full Text Available The risk of progression from exposure to the tuberculosis bacilli to the development of active disease is a two-stage process governed by both exogenous and endogenous risk factors. Exogenous factors play a key role in accentuating the progression from exposure to infection among which the bacillary load in the sputum and the proximity of an individual to an infectious TB case are key factors. Similarly endogenous factors lead in progression from infection to active TB disease. Along with well-established risk factors (such as human immunodeficiency virus (HIV, malnutrition, and young age, emerging variables such as diabetes, indoor air pollution, alcohol, use of immunosuppressive drugs, and tobacco smoke play a significant role at both the individual and population level. Socioeconomic and behavioral factors are also shown to increase the susceptibility to infection. Specific groups such as health care workers and indigenous population are also at an increased risk of TB infection and disease. This paper summarizes these factors along with health system issues such as the effects of delay in diagnosis of TB in the transmission of the bacilli.

    Full Text Available OBJECTIVE: To identify environment factors predicting sensory profile of infants between 4 and 18 months old. METHODS: This cross-sectional study evaluated 97 infants (40 females e 57 males, with a mean age of 1.05±0.32 years with the Test of Sensory Functions in Infants (TSFI and also asked 97 parents and 11 kindergarten teachers of seven daycare centers to answer the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS. The AHEMD-IS is a questionnaire that characterizes the opportunities in the home environment for infants between 3 and 18 months of age. We tested the association between affordances and the sensory profile of infants. Significant variables were entered into a regression model to determine predictors of sensory profile. RESULTS: The majority of infants (66% had a normal sensory profile and 34% were at risk or deficit. Affordances in the home were classified as adequate and they were good in the studied daycare centers. The results of the regression revealed that only daily hours in daycare center and daycare outside space influenced the sensory profile of infants, in particular the Ocular-Motor Control component. CONCLUSIONS: The sensory profile of infants was between normal and at risk. While the family home offered adequate affordances for motor development, the daycare centers of the infants involved demonstrated a good quantity and quality of affordances. Overall, we conclude that daily hours in the daycare center and daycare outside space were predictors of the sensory profile, particular on Ocular-Motor Control component.

    Full Text Available Introduction. Infants born between the 34[sup]th[/sup] – 36[sup]th[/sup] week of pregnancy account for 75% of all preterm infants. Their seemingly slight immaturity is related to serious health problems. Objective. The aim of the study was to analyse perinatal factors that influence the occurrence in infants of such problems as respiratory failure, metabolic problems and early onset sepsis (EOS. Materials and method. The material for the study included all mothers and their late preterm infants: 34+0 – 36+6 born in our hospital (a tertiary referral academic centre in 2010 and 2011. The course of pregnancy and delivery, the type of delivery, applied preventive measures and treatment, as well as demographic data and the clinical state of infants were all analysed. Data from individual documentation of each mother and infant were collected by 5 designated people and data reliability was independently monitored by a random control of the documentation conducted by the supervising person. Results. A statistically significant relationship between the occurrence of respiratory distress syndrome and infant immaturity, bad state after birth and sepsis in infants were confirmed. Sepsis was more common in the case of vaginal delivery, and coexisted with respiratory distress syndrome. The mother’s diseases during pregnancy, a perinatal preventive antibiotic therapy, and possible delivery complications did not influence the infection. Perinatal asphyxia in an infant positively correlated with a Caesarean section and respiratory distress syndrome after birth. Conclusions. It is necessary to thoroughly establish the type of delivery of a late preterm infant in order to prevent an infection in the newborn child. The improvement of diagnosis of intrauterine hypoxia may reduce the number of Caesarean sections. The decision about late preterm delivery should be based on indices of the mother’s state of health. Premature delivery is related to the

    The results of research on infants at high risk for schizophrenia (offspring of schizophrenic parents) are reviewed. The findings indicate that high-risk infants are not exposed to greater exogenous stress during the prenatal and perinatal periods, although subsequent caregiving provided by disturbed mothers may be nonoptimal. Several findings point to the existence of a constitutionally vulnerable subgroup of high-risk infants. Fetal and neonatal deaths, unrelated to obstetrical complications, may be more common among high-risk offspring, and neuromotor abnormalities are apparent in a subgroup of high-risk subjects across the life span. Moreover, there is evidence to suggest that offspring of schizophrenics are uniquely susceptible to obstetrical complications when they occur: Neuromotor deficits and other developmental deviations show a greater relationship with obstetrical complications among high-risk infants than controls. Taken together, the results lend support to the validity of interactional models of the etiology of schizophrenia and suggest that preventive intervention may be a realistic goal.

    ObjectiveTo investigate the correlated factors contributed to extrauterine growth restriction (EUGR) in preterm infants with the gestational age less than 34 weeks.MethodsA total of 694 preterm infants with the gestational ages less than 34 weeks were enrolled. They were classiifed into EUGR and non-EUGR groups by weight on discharge. The perinatal data, growth data, nutritional information and morbidities during hospitalization were compared between the two groups.ResultsEUGR on discharge occurred in 284 (40.9%) out of the 694 infants. The incidence of EUGR in intrauterine growth restriction (IUGR) infants was signiifcantly higher than in non-IUGR infants (P<0.01). The very low birth weight (VLBW) infants had a higher incidence of EUGR than non-VLBW infants (P<0.01). The incidence of EUGR increased with the decreases of gestational age at birth and birth weight (P<0.01). Compared with the non-EUGR group, the fasting time, the duration of parenteral nutrition, the time beginning to feed and the age to achieve full enteral feeds were signiifcantly greater in the EUGR group (P<0.01). The cumulative protein deifcit and cumulative caloric deifcit in the ifrst week of life in the EUGR group were higher than in the non-EUGR group (P<0.05). The incidences of respiratory distress syndrome, apnea, necrotizing enterocolitis and septicemia in the EUGR group were higher than in the non-EUGR group (P<0.05). The logistic regression analysis showed that birth weight, gestational age at birth and IUGR were the independent risk factors for EUGR.ConclusionsThe incidence of EUGR in infants with gestational age less than 34 weeks is high, especially in IUGR or VLBW infants. Early and aggressive nutritional strategy and prevention of apnea and septicemia may facilitate to reduce the occurrence of EUGR.%目的:研究34周以下早产儿宫外生长发育迟缓(EUGR)发生的相关因素。方法选取<34周早产儿694例,根据出院时体重分为EUGR组和非EUGR组,回顾

    This study investigates mothers' responses to infant communication among infants at heightened genetic risk (high risk) of autism spectrum disorder compared to infants with no such risk (low risk). A total of 26 infants, 12 of whom had an older sibling with autism spectrum disorder, were observed during naturalistic in-home interaction and semistructured play with their mothers at 13 and 18 months of age. Results indicate that overall, mothers of low-risk and high-risk infants were highly and similarly responsive to their infants' communicative behaviors. However, examination of infant vocal and gestural communication development together with maternal verbal responses and translations (i.e. verbally labeling a gesture referent) suggests that delays in early communication development observed among high-risk infants may alter the input that these infants receive; this in turn may have cascading effects on the subsequent development of communication and language. © The Author(s) 2013.

    Objective To analyse bronchopulmonary dysplasia (BPD) incidence and high risk factor in the small gestational age premature infants. Methods Retrospective analyse the materials of inpatient infants whose gestational age (GA) were =?2 weeks and survived over 28 days in our neonatal intensive care unite ( NICU). The 28 cases as BPD group met the new diagnostic criteria of BPD. The 56 cases as the control group were randomly selected from all the premature infant with no BPD. Results Total of 197 cases of premature infant were included in this study. The incidence of BPD is about 14.2%. There were statistical significance in each GA period group (x2 =32.269,/* =0.000). The incidence increased when the GA decreased; There were statistical significance in each birth weight group (x2 =30. 244, P =0. 000), the incidence increased when birth weight decreased. From the comparison of the 23 risk factors for BPD, we find thai 12 factors have statistical significance (P < 0. 05), those are GA, body weight, oxygen time, maximum oxygen treatment concentration, hospital days, tracheal intubation mechanical ventilation, replacement therapy with pulmonary surfactant, anemia, application of Meropenem, the ratio of tenth day body weight to birth weight, the first blood gas analysis scores after birth and oxygen index < 300. On the basis of Logistic regression analysis of GA, birth weight, the highest inhaled oxygen volume concentration, tracheal intubation mechanical ventilation, anemia, the ratio of tenth day body weight to birth weight, we find that body weight, the highest inhaled oxygen volume concentration, the ratio of tenth body weight to birth weight are high risk factors for BPD. By compared the 18 factors between mild BPD and moderate or severe BPD, we find that asphyxia, application of diuretic, oxygen time and first blood gas analysis scores after birth have statistical significance ( P < 0.05 ) . Conclusions The birth weight, the highest inhaled oxygen volume

    Low birthweight (LBW) is the main known determinant of infant mortality. In spite of the sharp decrease in infant mortality rates and of the rise in survival rates for children with LBW, no important decrease in LBW rates has been observed in Neuquen, Argentina. The purpose of this study was to try to understand the risk factors for LBW, the frequency of LBW in the population, and the role of prenatal care in its prevention, as well as to develop a risk factor scale that could be used to identify women at higher risk of giving birth to a child with LBW. With this in mind we performed a cross-sectional study based on 50% of the data entered into the Perinatal Information System for 1988-1995 by the 29 hospitals in Neuquen province (46,171 births). The distribution of birthweight and the frequency of potential risk factors for LBW were examined. The relationship between such factors and LBW was studied using a logistic regression model. On the basis of the results obtained, an additive scale was drawn up and validated with the remaining 50% of the data for registered births. The highest odds ratio (OR) was seen in women who had no prenatal care (OR = 8.78; 95%CI: 6.7 to 11.4). ORs for inadequate prenatal care, lateness in attending the first prenatal visit, preeclampsia or eclampsia, hemorrhage and anomalies of the placenta or placental membranes, and a history of a previous child with LBW were greater than 2.0. The risk of having children with LBW was also higher in women over the age of 40, women under 20, single women, smoking mothers, women with an intergenesic interval of less than 18 months, and women with a body mass index of less than 20. Finally, there was a direct linear relationship between points on the risk scale and the risk of having a LBW infant.

    Sudden infant death syndrome (SIDS) and sudden intrauterine unexpected death syndrome (SIUDS) are an unresolved teaser in the social-medical and health setting of modern medicine and are the result of multifactorial interactions. Recently, prenatal exposure to environmental contaminants has been associated with negative pregnancy outcomes, and verification of their presence in fetal and newborn tissues is of crucial importance. A gas chromatography-tandem mass spectrometry (MS/MS) method, using a triple quadrupole analyzer, is proposed to assess the presence of 20 organochlorine pesticides, two organophosphate pesticides, one carbamate (boscalid), and a phenol (bisphenol A) in human brain tissues. Samples were collected during autopsies of infants and fetuses that died suddenly without any evident cause. The method involves a liquid-solid extraction using n-hexane as the extraction solvent. The extracts were purified with Florisil cartridges prior to the final determination. Recovery experiments using lamb brain spiked at three different concentrations in the range of 1-50 ng g(-1) were performed, with recoveries ranging from 79 to 106%. Intraday and interday repeatability were evaluated, and relative standard deviations lower than 10% and 18%, respectively, were obtained. The selectivity and sensitivity achieved in multiple reaction monitoring mode allowed us to achieve quantification and confirmation in a real matrix at levels as low as 0.2-0.6 ng g(-1). Two MS/MS transitions were acquired for each analyte, using the Q/q ratio as the confirmatory parameter. This method was applied to the analysis of 14 cerebral cortex samples (ten SIUDS and four SIDS cases), and confirmed the presence of several selected compounds.

    The field of infant mental health promotion has rapidly developed in academia, health policy and practice. Although there are roots in earlier childhood health and welfare movements, recent developments in infant mental health promotion are distinct and different. This article examines the development and practice of infant mental health promotion in South Australia. A regional, intersectoral forum with a focus on families and young children was used as a case study. In-depth interviews with forum members were analysed using a governmentality lens. Participants identified a range of risks to the healthy development of the infant. The study suggests that the construction of risk acts as a technique of governing, providing the rationale for intervention for the child, the mother and the public's good. It places responsibility on parents to self-govern. Although the influence of broader social contexts is acknowledged, the problematisation of mothering as risk shifts the focus to individual capacity, rather than encompassing the systems and social conditions that support healthy relationships. This research suggests that the representations of risk are a pervasive and potent influence that can act to undermine health promotion efforts that seek to empower and enable people to have more control over their own health.

    In a multicentre case-control study of necrotising enterocolitis risk factors were found to vary with birthweight of cases. In very low birthweight cases the risk factors identified were those associated with prolonged or recurrent hypoxia (recurrent apnoea, respiratory distress, assisted ventilation, and umbilical artery catheterisation). In heavier birthweight infants the risk factors were, in contrast, related to hypoxia at birth (low 1 minute Apgar score and endotracheal intubation at bir...

    Life quality of the premature babies after rescuing successfully was gained more attention by perina-tal medical field and society with the more success rate of premature rescue. The brain injury is one of the main factors affecting the long term prognosis of the premature infants. The major risk factors of brain damage include gestational age and birth weight,intrauterine hypoxia and infection,the mode of delivery and whether the resuscitation and later treat-ment skills proper and skilled,and so on. So the key point of preventing the brain injury is avoiding premature delivery and extending the gestational age as much as possible. If the premature delivery could not evitable,the obstetrician should use adrenal cortex hormones before delivery to promote fetal lungs maturition,since the increasing application of cortical hormone prenatally and decreasing using that after birth have been shown good effects on long term prognosis of the nervous system in the preterm infants. It is also confirmed that application of magnesium sulfate prenatally could prevent the premature brain injury. There are still no agreements on the relationship between the delivery modes and the brain injury of extremely low birth weight infants. But prolonging the stage of labor is sure to increase the incidence of intracranial hemorrhage in the premature infants thereby affecting the long term prognosis. After birth,we should imple-ment the correct resuscitation processes by skilled and proper technical methods,in order to decrease the mortality and to improve the long term prognosis.%随着早产儿抢救成功率的日益提高,经抢救成活后的早产儿生命质量愈来愈受到围生医学界和社会的关注,其中脑损伤是影响早产儿远期愈后的主要因素之一。造成脑损伤的危险因素主要有出生时胎龄和体质量、宫内缺氧和感染、分娩方式的选择及后期复苏治疗技术方法是否恰当和熟练等。尽可能地避免早产和尽

    Full Text Available Breast cancer is the most frequently diagnosed neoplastic disease in women around menopause often leading to a significant reduction of these women’s ability to function normally in everyday life. The increased breast cancer incidence observed in epidemiological studies in a group of women actively participating in social and professional life implicates the necessity of conducting multidirectional studies in order to identify risk factors associated with the occurrence of this type of neoplasm. Taking the possibility of influencing the neoplastic transformation process in individuals as a criterion, all the risk factors initiating the process can be divided into two groups. The first group would include inherent factors such as age, sex, race, genetic makeup promoting familial occurrence of the neoplastic disease or the occurrence of benign proliferative lesions of the mammary gland. They all constitute independent parameters and do not undergo simple modification in the course of an individual’s life. The second group would include extrinsic factors conditioned by lifestyle, diet or long-term medical intervention such as using oral hormonal contraceptives or hormonal replacement therapy and their influence on the neoplastic process may be modified to a certain degree. Identification of modifiable factors may contribute to development of prevention strategies decreasing breast cancer incidence.

    Increasing globally, particularly in children, obesity is a serious public health issue and risk factor for overweight and metabolic disease in later life. Both in experimental animal and human studies, advances in gene sequencing technologies have yielded intriguing possibilities for the role of the gut microbiome in later development of overweight status. Before translating study findings into practice, we must first reconcile inconsistencies between animal experimentation, and human adult and infant studies. Recent evidence for associations with gut microbiota and infant weight gain or child weight status, implicate Bacteroides and Lactobacillus species. Dietary manipulation with human milk and pre/probiotic formulations holds promise for preventing obesity. PMID:25835047

    system (44.4%) and blood system(33.3%). Among 20 factors associated with pulmonary complications of MPP, age, feeding method (including artificial, mixing and milk three classification), season of onset, fever days, the titer of mycoplasma pneumonia (MP)-IgM, C-reaction protein, erythrocyte sedimentation rate and the initial time of using macrolides had significant differences between two groups (P<0.05). Multivariate Logistic regression analysis showed that age≥2 years, fever days≥7 d, titer of MP-IgM≥1∶160, increased C-reaction protein levels and accelerated erythrocyte sedimentation rate were the risk factors for pulmonary complications of infants MPP, while breastfeeding and using macrolides within 7 d were the protective factors. Conclusions The incidence rate of pulmonary complications in infants MPP is high, which can affect multiple systems. For children with older age, longer thermal process, higher titer of MP-IgM, and increased C-reaction protein , accelerated erythrocyte sedimentation rate and more past medical history, more attention should be paid for their higher pulmonary complications incidence.

    Risk of premature birth was evaluated retrospectively in 610 women in the first days after delivery using the prematurity risk score published by Thalhammer 1973. The calculated risk of premature birth was compared than prospectively to postpartal morbidity of the newborn infants as determined by duration of hospital stay, incidence of respiratory distress syndrome, need of artificial ventilation and mortality. A positive correlation could be found between risk of premature birth and postpartal morbidity of the newborn infants especially in small premature infants with birthweights of 2000 grams and less. The same correlation existed also in two groups of infants out of two different obstetric clinics which showed the same distribution of prenatal risks and the same prenatal care frequencies. It clearly becomes evident that infants with the same prenatal risks but good prenatal care during pregnancy had much lower hospital stays, lower respiratory distress frequencies and lower mortality rates than babies delivered from pregnancies badly cared for. These prenatal care related differences in postpartum morbidity again were much more evident in infants out of lower birth weight classes.

    It is unknown why some infants with perinatal stroke present clinical symptoms late during infancy and will be identified as infants with presumed perinatal stroke. The risk factors and clinical and radiological data of 42 infants with presumed perinatal stroke (69% with periventricular venous infarction and 31% with arterial ischemic stroke) from the Estonian Pediatric Stroke Database were reviewed. Children with presumed perinatal stroke were born at term in 95% of the cases and had had no risk factors during pregnancy in 43% of the cases. Children with periventricular venous infarction were born significantly more often (82%) vaginally (P = .0213) compared to children with arterial stroke (42%); nor did they require resuscitation (P = .0212) or had any neurological symptoms after birth (P = .0249). Periventricular venous infarction is the most common type of lesion among infants with the presumed perinatal stroke. Data suggest that the disease is of prenatal origin.

    2016-01-01

    Gallstone disease is one of the most common public health problems in the United States. Approximately 10%-20% of the national adult populations currently carry gallstones, and gallstone prevalence is rising. In addition, nearly 750,000 cholecystectomies are performed annually in the United States; direct and indirect costs of gallbladder surgery are estimated to be $6.5 billion. Cholelithiasis is also strongly associated with gallbladder, pancreatic, and colorectal cancer occurrence. Moreover, the National Institutes of Health estimates that almost 3,000 deaths (0.12% of all deaths) per year are attributed to complications of cholelithiasis and gallbladder disease. Although extensive research has tried to identify risk factors for cholelithiasis, several studies indicate that definitive findings still remain elusive. In this review, predisposing factors for cholelithiasis are identified, the pathophysiology of gallstone disease is described, and nonsurgical preventive options are discussed. Understanding the risk factors for cholelithiasis may not only be useful in assisting nurses to provide resources and education for patients who are diagnosed with gallstones, but also in developing novel preventive measures for the disease.

    Introducción: Es bien sabido que el genotipo HLA puede explicar un 40% del riesgo genético de enfermedad celíaca, por lo que otros factores de predisposición genéticos así como factores que sutilmente modulen la activación y diferenciación de células T necesitan ser estudiados. Esto incluye factores ambientales, de los que se cree actualmente que ejercen un efecto sobre el desarrollo del sistema inmune y la microbiota intestinal. Objetivo: Evaluar las asociaciones entre factores ambientales tempranos, las subpoblaciones de linfocitos y la composición de la microbiota intestinal en niños con riesgo familiar de enfermedad celíaca. Diseño del estudio: Estudio prospectivo observacional Sujetos: 55 niños de 4 meses de edad con al menos un familiar celíaco de primer grado. Los niños fueron clasificados de acuerdo al tipo de parto, ingesta materna de antibióticos durante el embarazo y durante el parto, tipo de lactancia, infecciones tempranas y toma de antibióticos, administración de la vacuna de rotavirus, y incidencia de alergias dentro de los 18 primeros meses de vida. Métodos: Las subpoblaciones de linfocitos y la composición de la microbiota intestinal fueron estudiadas a la edad de 4 meses. Resultados: La lactancia de fórmula y las infecciones tempranas se asociaron con un mayor número absoluto de células CD3+, CD4+, CD4+CD38+, CD4+CD28+ y CD3+CD4+CD45RO+ (P0.01). El parto por cesárea y la administración de la vacuna de rotavirus se asociaron a un menor porcentaje de células CD4+CD25+. La toma temprana de antibióticos se asoció y correlacionó con menor número de Bifidobacterium longum y mayor número de Bacteroides fragilis. Conclusiones: Las infecciones y la toma de antibióticos en los primeros 4 meses de edad son los factores ambientales tempranos más fuertemente y/o frecuentemente asociados a las subpoblaciones de linfocitos y la composición de la microbiota, respectivamente, en niños con riesgo de enfermedad celíaca.

O objetivo deste artigo é apresentar uma revisão bibliográfica acerca da depressão pós-parto. São abordados aspectos conceituais, epidemiológicos, fatores de risco associados a sua ocorrência e algumas repercussões da depressão pós-parto na relação materno-infantil e no desenvolvimento da criança. O conhecimento destes aspectos reveste-se de grande importância considerando as conseqüências prejudiciais às mães bem como ao desenvolvimento cognitivo, social e emocional de suas crianças.The post-partum depression is a condition that affects 10 to 15% of the women in the post-partum period. These symptoms begin at some moment during the first year after delivery, occurring more frequently between the fourth and eighth week after parturition. It is generally expressed through a complexity of symptoms where there is a presence of irritability, frequent crying, feelings of abandonment and hopelessness, lack of energy and motivation, lack of sexual interest, disturbances in sleep and eating patterns, anxiety, and feelings of not being able to cope with new demands. The objective of this paper is to present a bibliographical revision regarding the post-partum depression. Conceptual and epidemiological aspects, risk factors associated with their occurrence as well as a few repercussions of the post-partum depression in the mother-child relation, and the development of the infant will be broached.

    Background: exclusive breastfeeding has been shown to protect infants from contracting various diseases. The aims of this study were: to examine the relationships between infant feeding patterns and the risk of Acute Respiratory Infections (ARI, and to assess the importance of some factors that can increase such risk.

    Methods: a case-control study was carried out during the period between February 1st 2005 - May 1st 2005. The study included 137 infants who were hospitalized in the Children Welfare Teaching Hospital for ARIs during the period of study (a case definition of acute lower respiratory infection as given by the WHO (1995 was used. The Control group included 157 healthy infants who were randomly selected from two primary health care centers of the AI-Karkh sector of Baghdad for immunization. The risk of various factors thought to be associated to ARI were studied, these being: non-modifiable (age, gender, birth order, parent education, crowded residence, family history of asthma and history of ARIs in household members in previous 2 weeks and modifiable (short duration of breastfeeding, cigarette smoking in proximity to the infant, delayed immunization and malnutrition. Logistic regression was used to adjust for confounders and for calculating adjusted odds ratios.

    Results: formula fed infants had a 2.7 times higher risk (CI:1.6-4.68 for ARIs compared to breast fed infants. Infants who had undergone a short duration of breastfeeding (<3 months had a 1.4 times increased risk or ARI (CI: 0.89—2.23. Additional factors that were associated with higher ARIs were, female gender (OR= 2.0, CI:1.3-3.3, low educational level of mothers (OR= 6.4, CI:3.2-12.7 and fathers (OR=4.5, CI:2.27-8.78, crowded residence (OR= 4.5, CI: 2.6-7.8, positive history of ARIs in household members in the 2 weeks prior to the study (OR= 5.5, CI:3.3-9.3, family history of asthma (OR = 2.6, CI:1

    Object sharing abilities of infants at risk for autism (AR infants) and typically developing (TD) infants were compared from 9 to 15 months of age. Specifically, we examined the effects of infants’ locomotor abilities on their object sharing skills. 16 TD infants and 16 AR infants were observed during an “object sharing” paradigm at crawling and walking ages. Overall, AR walking infants demonstrated lower rates of object sharing with caregivers compared to TD walking infants. Specifically, AR walking infants had lower rates of giving and approaches toward caregivers compared to TD walking infants. AR walking infants also had lower step rates toward task-appropriate targets, i.e. caregivers and objects compared to TD walking infants. No group differences in object sharing were observed at crawling ages. Object sharing could be a valuable context for early identification of delays in infants at risk for developing ASD.

    Evidence suggests that children and adults diagnosed with autism spectrum disorders (ASD) exhibit difficulties with postural control. Retrospective video studies of infants later diagnosed with ASD indicate that infants who eventually receive an ASD diagnosis exhibit delays in postural development. This study investigates early posture development prospectively and longitudinally in 22 infants at heightened biological risk for ASD (HR) and 18 infants with no such risk (Low Risk; LR). Four HR infants received an autism diagnosis (AD infants) at 36 months. Infants were videotaped at home at 6, 9, 12, and 14 months during everyday activities and play. All infant postures were coded and classified as to whether or not they were infant-initiated. Relative to LR infants, HR infants were slower to develop skill in sitting and standing postures. AD infants exhibited substantial delays in the emergence of more advanced postures and initiated fewer posture changes. Because posture advances create opportunities for infants to interact with objects and people in new and progressively more sophisticated ways, postural delays may have cascading effects on opportunities for infant exploration and learning. These effects may be greater for infants with ASD, for whom posture delays are more significant.

    It is estimated that at least 80% of patients with cardiovascular disease (CVD) have conventional risk factors and optimization of these risk factors can reduce morbidity and mortality due to this disease considerably. Contemporary women have increased burden of some of these risk factors such as obesity, metabolic syndrome and smoking. Turkish women have a worse CV risk profile than Turkish men in some aspects. Risk stratification systems such as Framingham have a tendency of underestimating the risk in women. Coronary artery disease remains in vessel wall for a longer period of time in women; therefore obstructive disease appear later in their lifespan necessitating risk stratification systems for estimating their lifetime risk.

    Full Text Available The language difficulties often seen in individuals with autism might stem from an inability to integrate audiovisual information, a skill important for language development. We investigated whether 9-month-old siblings of older children with autism, who are at an increased risk of developing autism, are able to integrate audiovisual speech cues. We used an eye-tracker to record where infants looked when shown a screen displaying two faces of the same model, where one face is articulating/ba/and the other/ga/, with one face congruent with the syllable sound being presented simultaneously, the other face incongruent. This method was successful in showing that infants at low risk can integrate audiovisual speech: they looked for the same amount of time at the mouths in both the fusible visual/ga/- audio/ba/and the congruent visual/ba/- audio/ba/displays, indicating that the auditory and visual streams fuse into a McGurk-type of syllabic percept in the incongruent condition. It also showed that low-risk infants could perceive a mismatch between auditory and visual cues: they looked longer at the mouth in the mismatched, non-fusible visual/ba/- audio/ga/display compared with the congruent visual/ga/- audio/ga/display, demonstrating that they perceive an uncommon, and therefore interesting, speech-like percept when looking at the incongruent mouth (repeated ANOVA: displays x fusion/mismatch conditions interaction: F(1,16 = 17.153, p = 0.001. The looking behaviour of high-risk infants did not differ according to the type of display, suggesting difficulties in matching auditory and visual information (repeated ANOVA, displays x conditions interaction: F(1,25 = 0.09, p = 0.767, in contrast to low-risk infants (repeated ANOVA: displays x conditions x low/high-risk groups interaction: F(1,41 = 4.466, p = 0.041. In some cases this reduced ability might lead to the poor communication skills characteristic of autism.

    Background Inadequate maternal nutrition is regarded as one of the most important indicators of fetal growth. The aim of this study was to analyze the associated risk of having a small for gestational age (SGA) infant according to the mother's dairy intake during the first half of pregnancy. Methods A prospective cohort study was performed using 1175 healthy pregnant women selected from the catchment area of Virgen de las Nieves University Hospital, Granada (Spain). SGA was defined as neonates weighing less than the 10th percentile, adjusted for gestational age. Factors associated with SGA were analyzed using logistic regression models. Population attributable fractions of SGA according to dairy intake were estimated. Results Dairy intake among women who gave birth to SGA infants was 513.9, versus 590.3 g/day for women with appropriate size for gestational age infants (P = 0.003). An increased intake of dairy products by 100 g/day during the first half of pregnancy decreased the risk of having a SGA infant by 11.0 %, aOR = 0.89 (0.83, 0.96). A dose-response gradient between dairy intake and SGA was observed. Conclusions An inadequate intake of dairy products is associated with a higher risk of SGA. Our results suggest a possible causal relation between dairy intake during pregnancy and the weight of the newborn, although we cannot discard residual confounding. These results should be further supported by properly designed studies.

    Objective This study examined the role that easy infant temperament and cumulative environmental risk play in predicting cognitive, language and behavioral outcomes in 3 year-old children at high social risk. Methods Subjects were 412 mother-infant dyads, recruited at birth, participating in a longitudinal study examining the effects of prenatal methamphetamine (MA) on child development. This analysis includes a subsample (n=290) of the study with a completed 3 year visit. Temperament was assessed by the Infant Behavior Questionnaire at 12 mos. Factor analysis from well-validated measures generated “easy” and “difficult” temperament profiles, and a profile for high risk environment. Caretaker receptive vocabulary served as a proxy for IQ. Outcomes at 3 years included motor and mental development, behavior problems, and language. Linear regression and hierarchical linear modeling examined the effects of temperament, high risk environment and caregiver receptive language on outcomes adjusting for maternal drug use, demographic, and socioeconomic covariates. Results Internalizing and externalizing behaviors were lower in children with easy temperament and higher with increased environmental risk. Easy temperament attenuated behavioral problems only in the setting of lower environmental risk. Caregiver receptive language was associated with lower internalizing scores High risk environment and temperament factors were not related to cognitive or motor outcomes. Prenatal MA exposure was not associated with 3 year-old outcomes, nor did it alter the protective effects of an easier temperament on child behavior. Conclusions Children growing up in adverse social environments had increased behavioral problems and compromised language development. Conversely, an easy temperament acts as a protective factor for social-emotional development and could be related to resilience. PMID:21200329

Studied theoretical and methodological aspects of the risk classification of factoring operations in the part of the risk assessment factors. It is proposed to consider the risks factors as the risk that is acceptable controlled by accounting instruments and the risks that can not be taken into account in the accounting records. To minimize the risk factor, accounting-driven tools, a method of self-insurance, which is a factor in the creation of provision for factoring transactions designed to cover unexpected expenses and losses. Provision for factoring factor will establish more stable conditions of financial activity and avoid the fluctuations of profit factor in relation to the writing off of losses on factoring operatsіyam.Developed proposals allow for further research to improve the organizational and methodological basis of accounting and analysis of information as a basis for providing risk management factor, particularly in terms of improving the evaluation questions such risks and their qualitative and quantitative analysis.

    Full Text Available Background Atopic dermatitis is the first manifestation of allergic disease in early life. Early interventions may prevent the development of allergy disease. Allergy trace cards have been used to identify the level of allergic risk, based on family atopy scores. Because environmental factors may also influence the development of atopic dermatitis, the usefulness of the allergy trace card needs to be reevaluated. Objective To compare the incidence of atopic dermatitis in infants aged 0-4 months with total family atopy scores of > 0 to those with scores of 0. Methods We conducted this cohort study from June 1, 2012 to December 31, 2012 at Sanglah Hospital, Denpasar. Family atopy score was tabulated from all pregnant woman in the Obstetric Outpatient Clinic and the Maternity Room. Subjects were divided into two groups based on their total family atopy score: those with scores > 0 and those with scores of 0. The appearance of atopic dermatitis symptoms in the infants were evaluated until they reached 4 months of age. The incidence of atopic dermatitis in two groups was compared using Chi-square test. Results The incidence of atopic dermatitis in this study was 10.9%. The group with total family atopy scores of 0 had a significantly higher incidence of atopic dermatitis than the group with scores > 0 (adjusted RR 22.5; 95%CI 8.8 to 57.0; P = 0.001. Conclusion The incidence of atopic dermatitis is higher in infants with total family atopy score > 0 and this group has a 22.5 times higher risk of atopic dermatitis compared to infants with total family atopy score of 0. Allergy trace cards are relevant in differentiating the risk of atopy with regards to development of atopic dermatitis. We suggest that family atopy scores be evaluated during antenatal care in order to limit the development of atopic dermatitis in infants. [Paediatr Indones. 2014;54:330-7.].

    Full Text Available Elevated blood lead levels (BLL and malaria carry an important burden of disease in West Africa. Both diseases might cause anemia and they might entail long-term consequences for the development and the health status of the child. Albeit the significant impact of malaria on lead levels described in Nigeria, no evaluation of the effect of elevated BLL on malaria risk has been investigated so far.Between 2010 and 2012, blood lead levels of 203 Beninese infants from Allada, a semi-rural area 50km North from Cotonou, were assessed at 12 months of age. To assess lead levels, blood samples were analyzed by mass spectrometry. In parallel, clinical, microbiological and hematological data were collected. More precisely, hemoglobin, serum ferritin, CRP, vitamin B12, folate levels, and Plasmodium falciparum parasitemia were assessed and stool samples were also analyzed.At 12 months, the mean BLL of infants was 7.41 μg/dL (CI: 65.2; 83, and 128 infants (63% had elevated blood lead levels, defined by the CDC as BLL>5 μg/dL. Lead poisoning, defined as BLL>10 μg/dL, was found in 39 infants (19%. Twenty-five infants (12.5% had a positive blood smear at 12 months and 144 infants were anemic (71%, hemoglobin<110 g/L. Elevated blood lead levels were significantly associated with reduced risk of a positive blood smear (AOR = 0.38, P-value = 0.048 and P. falciparum parasite density (beta-estimate = -1.42, P-value = 0.03 in logistic and negative binomial regression multivariate models, respectively, adjusted on clinical and environmental indicators.Our study shows for the first time that BLL are negatively associated with malarial risk considering other risk factors. Malaria is one of the main causes of morbidity and mortality in infants under 5 years worldwide, and lead poisoning is the 6th most important contributor to the global burden of diseases measured in disability adjusted life years (DALYs according to the Institute of Health Metrics.

    To determine infant diaper dermatitis (DD) at pediatrics health center; its relation to socio-demographic factors and infant care. The study included 113 infants aged 0-24 mo. Data on infants' age, sex, weight, mothers' education, nutrition, diaper change frequency, cleaning methods and prophylactic cream use were recorded. Infants with minimum one time rash, were accepted to have DD. Seventy six (67.3 %) infants had DD [32 girls (42.1 %), 44 boys (57 %), mean age: 6.5 mo]. Infants with DD had significantly higher age than those without (p 0.001). DD frequency in infants ≥4.5 mo-old was 5.8(2.4-13.7) times more than in infants ≤4.5 mo. Cleaning material types did not affect DD frequency. No significant difference was observed in DD with diaper change of ≤3 times and ≥4 times. Significant difference in DD increase was observed with supplementary food intake vs. without it (p 0.000). DD frequency in infants with supplementary food intake was 6.4 times (2.4-17.1) more than in those without it. Human milk intake was statistically significant in causing less occurrence of DD as shown in univariate model (p food intake and lack of cream use seem to be accountable for DD whereas human milk intake lessened the occurrence of DD. Mothers should be informed on dermatitis care and encouraged for breastfeeding.

Materials and Methods: Distortion product OAEs (DPOAEs and brainstem evoked response audiometry (BERA recordings were obtained for 30 controls and 100 infants with one or more high risk factors, in a sound treated room and the results were interpreted. ABR peak latencies, amplitudes, and waveform morphology in high risk infants were compared with those in control group. DPOAE as screening test was evaluated in terms of various parameters with BERA/ABR taken as gold standard. Results: Absolute latencies of Wave I and Wave V and interpeak latency of I-V were significantly prolonged in high risk group as compared to control group. The most common causes to contribute significantly for hearing impairment were found to be hyperbilirubinemia, birth asphyxia, meningitis/septicemia. DPOAE when compared with ABR taken as gold standard showed that sensitivity of the test was 87.7% (74.5%-94.9% and specificity was 74.5% (60.0%-85.2%. Positive predictive value was 76.7% (63.2%-86.6% and negative predictive value of the test was 86% (71.9%-94.3%. Positive likelihood ratio was 0.29 (0.18-0.46 and negative likelihood ratio was 6.08 (2.82-13.09. Conclusion : ABR/BERA, though highly reliable, is a tedious and time consuming test. DPOAE is a simple and rapid test with relatively higher acceptability but low sensitivity and specificity; therefore, limits its role as independent screening test. DPOAE-ABR test series is an effective way to screen all the high risk infants at the earliest.

Preeclampsia may present at any gestation but is more commonly encountered in the third trimester. Multiple risk factors have been documented, including: family history, nulliparity, egg donation, diabetes, and obesity. Significant progress has been made in developing tests to predict risk of preeclampsia in pregnancy, but these remain confined to clinical trial settings and center around measuring angiogenic profiles, including placental growth factor or newer tests involving metabolomics. Less progress has been made in developing new treatments and therapeutic targets, and aspirin remains one of the few agents shown to consistently reduce the risk of developing preeclampsia. This review serves to discuss recent advances in risk factor identification, prediction techniques, and management of preeclampsia in antenatal, intrapartum, and postnatal patients.

    To analyze maternal and neonatal complications among late preterm birth cases and to investigate risk factors of late preterm birth. Methods This was a retrospective analysis of 258 late preterm cases (late preterm group) born in Peking University First Hospital from January 1, 2009 to December 31, 2010. Maternal comorbidity and complications, delivery modes, and neonatal complications of these 258 late preterm infants were compared with 308 term cases (term group) during the same period. Statistical analysis was performed usingχ2 test, Fisher's exact probability test, t test and logistic regression. Results In Peking University First Hospital, late preterm births accounted for 3.9%(258/6 695) of live births and 60.1%(258/429) of preterm births. The incidence of the following maternal complications among the late preterm group was higher than that among term group(all P<0.05): severe pre-eclampsia [7.4%(19/258) vs 1.0%(3/308), χ2=15.35]; preterm rupture of membrane [42.6%(110/258) vs 15.3%(47/308), χ2=52.49];cervical insufficiency [1.9%(5/258) vs 0.0%(0/308), Fisher's exact test];placenta previa[3.5%(9/258) vs 0.6%(2/308), Fisher's exact test] and placental abruption [2.7%(7/258) vs 0.3%(1/308), Fisher's exact test]. Severe pre-eclampsia was the major risk factor leading to late preterm birth. The incidence of the following neonatal complications among the late preterm group was higher than that among term group (all P<0.05):respiratory distress syndrome (NRDS) [11.6%(30/258) vs 1.6%(5/308), χ2=24.22]; hyperbilirubinemia [64.3%(166/258) vs 39.6%(122/308),χ2=34.36];electrolyte disturbance [12.8%(33/258) vs 1.6(95/308),χ2=27.96];hypothermia [7.0%(18/258) vs 2.9%(9/308),χ2=5.08];infectious pneumonia[13.6%(35/258) vs 3.2%(10/308), χ2=20.43]; leukoencephalopathy [3.1%(8/258) vs 0.3%(1/308), χ2=5.25]; low body temperature [18.6%(48/258) vs 3.6%(11/308),χ2=33.98] and neonatal asphyxia [6.2%(16/258) vs 1.0%(3/308),χ2=11.86].

    Objective: To investigate the association between breastfeeding and infant acquired infection of Hepatitis C Virus(HCV). Methods: To obtain studies eligible for META-analysis, China biological medicine discs(CBMD) and MEDLINE citations were surveyed. Criteria for enrollment of published studies for META-analysis were based on principle by Abdolmaleky HM[1]. Odd ratio(OR) was calculated and summarized by fixed effect model or random effects using RevMan software. The heterogeneity of ORs was assessed using an χ2 test of goodness of fit. The significance of the pooled OR was determined by the z-test. The strength of association was summarized usingOR. An OR>1.0 indicated a positive association between the risk factor and infants HCV infection. Results:After searching in Medline and CBMD, 120 articles were enrolled for further identification. Thirty-seven were of review on relative fields and were excluded. Abstracts of remaining articles were carefully read, and finally, only 6 articles met, the standards for enrollment criteria. After analysis of the factor concerned, no significant association was found between breastfeeding and infant HCV infection, with a pooled OR equal to 0.60(95%CI = 0.22-1.60), and proved not to be of risk factors on infant acquired infection of HCV. Conclusion: Breastfeeding dose not increase the risk of infant acquired infection of HCV.

    Risk factors play an important role in an individual's response to periodontal infection. Identification of these risk factors helps to target patients for prevention and treatment, with modification of risk factors critical to the control of periodontal disease. Shifts in our understanding of periodontal disease prevalence, and advances in scientific methodology and statistical analysis in the last few decades, have allowed identification of several major systemic risk factors for periodontal disease. The first change in our thinking was the understanding that periodontal disease is not universal, but that severe forms are found only in a portion of the adult population who show abnormal susceptibility. Analysis of risk factors and the ability to statistically adjust and stratify populations to eliminate the effects of confounding factors have allowed identification of independent risk factors. These independent but modifiable, risk factors for periodontal disease include lifestyle factors, such as smoking and alcohol consumption. They also include diseases and unhealthy conditions such as diabetes mellitus, obesity, metabolic syndrome, osteoporosis, and low dietary calcium and vitamin D. These risk factors are modifiable and their management is a major component of the contemporary care of many periodontal patients. Genetic factors also play a role in periodontal disease and allow one to target individuals for prevention and early detection. The role of genetic factors in aggressive periodontitis is clear. However, although genetic factors (i.e., specific genes) are strongly suspected to have an association with chronic adult periodontitis, there is as yet no clear evidence for this in the general population. It is important to pursue efforts to identify genetic factors associated with chronic periodontitis because such factors have potential in identifying patients who have a high susceptibility for development of this disease. Many of the systemic risk factors

    Full Text Available BACKGROUND Infant Mortality Rate (IMR is high in India. Identification of risk factors of mortality in neonatal illness is essential to reduce Neonatal Mortality Rate (NMR and ultimately the IMR. AIM To identify the risk factors of mortality in neonatal illness. SETTING AND DESIGN It was a nested case control study done at the sick neonatal unit of urban tertiary referral centre. METHODS AND MATERIALS After obtaining ethical committee approval, retrospective analysis of 150 out born neonatal case records of babies admitted during the period from October 2015 to December 2015 was done. Data such as demographic features, maternal details, referral details, perinatal events, clinical features, laboratory reports and outcome were recorded. STATISTICAL ANALYSIS These risk factors were subjected to univariate and multivariate logistic regression analysis and P value calculated for the same to find out significant risk factors of mortality in neonatal illness. RESULTS Neonatal mortality rate was 22%. Male-to-female ratio was 2:1, death occurred more commonly in female neonates (23.1%. Home deliveries carried more risk of mortality. Birth order 4 and above had 25% mortality. Neonates of mother who had primary education and below had higher mortality. Perinatal asphyxia and sepsis were the most common causes of neonatal mortality. By univariate analysis, preterms had 4.9 times increased risk of mortality than term babies. Apnoeic spells, chest retractions and shock had 8 times, 3 times and 3.6 times increased risk of mortality respectively. By multivariate analysis, birth weight below 2 kilograms (kg carried 11.8 times more risk of mortality with a p value 0.00 (95% C.I 3.2, 30.4 and poor maternal intake of iron and folic acid tablets was 3.9 times more risk p value 0.003 (95% C.I 1.6, 9.6, apnoeic spells were 5.8 times more risk of mortality with p value 0.02 (95% C.I 1.3, 26.2.

  7. Environmental risk factors for autism

    2011-04-01

    Full Text Available Autism is a devastating childhood condition that has emerged as an increasing social concern just as it has increased in prevalence in recent decades. Autism and the broader category of autism spectrum disorders are among the increasingly seen examples in which there is a fetal basis for later disease or disorder. Environmental, genetic, and epigenetic factors all play a role in determining the risk of autism and some of these effects appear to be transgenerational. Identification of the most critical windows of developmental vulnerability is paramount to understanding when and under what circumstances a child is at elevated risk for autism. No single environmental factor explains the increased prevalence of autism. While a handful of environmental risk factors have been suggested based on data from human studies and animal research, it is clear that many more, and perhaps the most significant risk factors, remain to be identified. The most promising risk factors identified to date fall within the categories of drugs, environmental chemicals, infectious agents, dietary factors, and other physical/psychological stressors. However, the rate at which environmental risk factors for autism have been identified via research and safety testing has not kept pace with the emerging health threat posed by this condition. For the way forward, it seems clear that additional focused research is needed. But more importantly, successful risk reduction strategies for autism will require more extensive and relevant developmental safety testing of drugs and chemicals.

  8. [Preeclampsia as cardiovascular risk factor].

    Heida, Karst Y; Franx, Arie; Bots, Michiel L

    2013-01-01

    Cardiovascular diseases (CVD) are the primary cause of death in women. Guidelines for identifying high-risk individuals have been developed, e.g. the Dutch Guideline on Cardiovascular Risk Management. In the most recent version of this guideline, diabetes mellitus (DM) and rheumatoid arthritis (RA) are cited as cardiovascular risk factors; therefore, individuals with these conditions are identified as being at high risk. As with DM and RA, there is strong evidence that the experience of having a hypertensive disorder during pregnancy is a cardiovascular risk factor. This is particularly the case for early preeclampsia, which constitutes a 7-fold increased risk of ischemic heart disease. However, in the Netherlands, there are no guidelines and there is no consensus on how to screen or treat these women. Trial evidence is therefore urgently needed to substantiate the value of cardiovascular risk management for those women with a history of hypertension during pregnancy.

    Infant mortality is one of the priority public health issues in developing countries like Nepal. The infant mortality rate (IMR) was 48 and 46 per 1000 live births for the year 2006 and 2011, respectively, a slight reduction during the 5 years' period. A comprehensive analysis that has identified and compared key factors associated with infant mortality is limited in Nepal, and, therefore, this study aims to fill the gap. Datasets from Nepal Demographic and Health Surveys (NDHS) 2006 and 2011 were used to identify and compare the major factors associated with infant mortality. Both surveys used multistage stratified cluster sampling techniques. A total of 8707 and 10,826 households were interviewed in 2006 and 2011, with more than 99% response rate in both studies. The survival information of singleton live-born infants born 5 years preceding the two surveys were extracted from the 'childbirth' dataset. Multiple logistic regression analysis using a hierarchical modelling approach with the backward elimination method was conducted. Complex Samples Analysis was used to adjust for unequal selection probability due to the multistage stratified cluster-sampling procedure used in both NDHS. Based on NDHS 2006, ecological region, succeeding birth interval, breastfeeding status and type of delivery assistance were found to be significant predictors of infant mortality. Infants born in hilly region (AOR = 0.43, p = 0.013) and with professional assistance (AOR = 0.27, p = 0.039) had a lower risk of mortality. On the other hand, infants with succeeding birth interval less than 24 months (AOR = 6.66, p = 0.001) and those who were never breastfed (AOR = 1.62, p = 0.044) had a higher risk of mortality. Based on NDHS 2011, birth interval (preceding and succeeding) and baby's size at birth were identified to be significantly associated with infant mortality. Infants born with preceding birth interval (AOR = 1.94, p = 0.022) or succeeding

    Physiological reactivity to repeated infant crying was examined as a predictor of risk for harsh discipline use with 12-month-olds in a longitudinal study with 48 low-income mother-infant dyads. Physiological reactivity was measured while mothers listened to three blocks of infant cry sounds in a standard cry paradigm when their infants were 3 months old. Signs of harsh discipline use were observed during two tasks during a home visit when the infants were 12 months old. Mothers showing signs of harsh discipline (n = 10) with their 12-month-olds were compared to mothers who did not (n = 38) on their sympathetic (skin conductance levels [SCL]) and parasympathetic (respiratory sinus arrhythmia) reactivity to the cry sounds. Results showed a significant interaction effect for sympathetic reactivity only. Mean SCL of harsh-risk mothers showed a significant different response pattern from baseline to crying and onward into the recovery, suggesting that mean SCL of mothers who showed signs of harsh discipline continued to rise across the repeated bouts of cry sounds while, after an initial increase, mean SCL level of the other mothers showed a steady decline. We suggest that harsh parenting is reflected in physiological overreactivity to negative infant signals and discuss our findings from a polyvagal perspective.

    The development of the neonatal gut microbiome is influenced by multiple factors, such as delivery mode, feeding, medication use, hospital environment, early life stress, and genetics. The dysbiosis of gut microbiota persists during infancy, especially in high-risk preterm infants who experience lengthy stays in the Neonatal intensive care unit (NICU). Infant microbiome evolutionary trajectory is essentially parallel with the host (infant) neurodevelopmental process and growth. The role of the gut microbiome, the brain-gut signaling system, and its interaction with the host genetics have been shown to be related to both short and long term infant health and bio-behavioral development. The investigation of potential dysbiosis patterns in early childhood is still lacking and few studies have addressed this host-microbiome co-developmental process. Further research spanning a variety of fields of study is needed to focus on the mechanisms of brain-gut-microbiota signaling system and the dynamic host-microbial interaction in the regulation of health, stress and development in human newborns.

Further research spanning a variety of fields of study is needed to focus on the mechanisms of brain-gut-microbiota signaling system and the dynamic host-microbial interaction in the regulation of health, stress and development in human newborns.

    Respiratory syncytial virus (RSV) is the most frequent cause of hospitalization and an important cause of death in infants in the developing world. The relative contribution of social, biologic, and clinical risk factors to RSV mortality in low-income regions is unclear. To determine the burden and risk factors for mortality due to RSV in a low-income population of 84,840 infants. This was a prospective, population-based, cross-sectional, multicenter study conducted between 2011 and 2013. Hospitalizations and deaths due to severe lower respiratory tract illness (LRTI) were recorded during the RSV season. All-cause hospital deaths and community deaths were monitored. Risk factors for respiratory failure (RF) and mortality due to RSV were assessed using a hierarchical, logistic regression model. A total of 2,588 (65.5%) infants with severe LRTI were infected with RSV. A total of 157 infants (148 postneonatal) experienced RF or died with RSV. RSV LRTI accounted for 57% fatal LRTI tested for the virus. A diagnosis of sepsis (odds ratio [OR], 17.03; 95% confidence interval [CI], 13.14-21.16 for RF) (OR, 119.39; 95% CI, 50.98-273.34 for death) and pneumothorax (OR, 17.15; 95% CI, 13.07-21.01 for RF) (OR, 65.49; 95% CI, 28.90-139.17 for death) were the main determinants of poor outcomes. RSV was the most frequent cause of mortality in low-income postneonatal infants. RF and death due to RSV LRTI, almost exclusively associated with prematurity and cardiopulmonary diseases in industrialized countries, primarily affect term infants in a developing world environment. Poor outcomes at hospitals are frequent and associated with the cooccurrence of bacterial sepsis and clinically significant pneumothoraxes.

    Infants are vulnerable to surrounding environment and they receive large influence from even a small change. As their body composition is not complete yet, infants receive huge impact from small pressure. Small change can cause disease or even death of infants. This paper designed and implemented a risk-detection system for infants. In addition to the fundamental function of safety management system, the risk-detection system implemented in this paper in corporate child-caring function by using a variety of sensors.

    There are two major nationwide birth cohort studies in Japan, namely, the Longitudinal Survey of Newborns in the 21st Century conducted by the Ministry of Health, Labor and Welfare (MHLW) and the Japan Environment and Children's Study (JECS) conducted by the Ministry of Environment. The former was a longitudinal questionnaire survey focusing on environmental and socioeconomic factors for descriptive epidemiology conducted every year since 2001 by mail. The latter was based on 15 unit centers nationwide with environmental measurements and collection of biological samples for environmental risk evaluation. Both are prospective birth cohort studies whose findings will be expected as the basis for establishing health policies. The data obtained in the former study can be used for research with permission from MHLW. To date, there have been more than ten published studies using those data. We have reviewed these studies and introduced our preliminary findings on factors affecting infant growth. Employment before delivery, educational background of parents, household income, and smoking habit of both parents have been suggested to affect infant growth. We will analyze the associations between socioeconomic factors and infant growth trajectory to elucidate the most adequate intervention for children.

Foram utilizadas informações de artigos publicados em revistas científicas, teses e publicações de organizações internacionais. O crescimento infantil se constitui em um dos melhores indicadores de saúde da criança e o retardo estatural representa atualmente, a característica antropométrica mais representativa do quadro epidemiológico da desnutrição no Brasil. Ressaltando a importância do fator genético no crescimento, a revisão abrange com maior ênfase a atuação dos fatores extrínsecos, sabendo-se que o processo de crescimento resulta da interação entre a carga genética e os fatores do meio ambiente, os quais premitirão a maior ou menor expressão do potencial genético. Face a comprovada natureza multicausal do crescimento infantil, vários estudos têm sido desenvolvidos, buscando relacionar variáveis biológicas, socioeconômicas, maternas, ambientais, culturais, demográficas, nutricionais, entre outras, com a sua etiologia, seu desenvolvimento e sua manutenção. A revisão apresentada reforça o interesse em investigações sobre o crescimento na primeira infância que devem ser permanentes, devido, principalmente, às repercussões a longo prazo sobre a saúde infantil.This review focuses on factors interfering with growth during the first years of life.

    2015-07-01

    This study evaluated the extent to which developmental change in coordination of social communication in early infancy differentiates children eventually diagnosed with ASD from those not likely to develop the disorder. A prospective longitudinal design was used to compare nine infants at heightened risk for ASD (HR) later diagnosed with ASD, to 13 HR infants with language delay, 28 HR infants with no diagnosis, and 30 low risk infants. Hierarchical linear modeling analyses revealed that ASD infants exhibited significantly slower growth in coordinations overall and in gestures coordinated with vocalizations, even relative to HR infants with language delay. Disruption in the development of gesture-vocalization coordinations may result in negative cascading effects that adversely impact later social and linguistic development.

    Epidemiological evidence for an effect of breastfeeding on asthma continues to be inconclusive. The present prospective study examined the relationship between breastfeeding and the risk of wheeze and asthma in Japanese infants. A birth cohort of 763 infants was followed. The first survey during pregnancy and the second survey between 2 and 9 months postpartum collected information on potential confounding factors. Data on breastfeeding, wheeze, and asthma were obtained from questionnaires in the third survey from 16 to 24 months postpartum. Adjustment was made for maternal age, maternal and paternal history of asthma, atopic eczema, and allergic rhinitis, indoor domestic pets (cats, dogs, birds, or hamsters), family income, maternal and paternal education, maternal smoking during pregnancy, baby's sex, baby's older siblings, household smoking in the same room as the infant, and time of delivery before the third survey. By the third survey, the cumulative incidence of wheeze and asthma was 22.1% and 4.3%, respectively. Neither exclusive breastfeeding for 4 months or more nor partial breastfeeding for 6 months or more were materially related to the risk of wheeze. No measurable association was observed between exclusive breastfeeding for 4 months or more and the risk of asthma. Partial breastfeeding for 6 months or more was inversely related to the risk of asthma although the adjusted odds ratio (OR) was not statistically significant. When infants were stratified according to whether there was a negative or positive allergic history in at least 1 parent, a nearly 40% and 60% decrease, respectively, in the ORs were found for exclusive and partial breastfeeding only in infants without a parental allergic history, although the ORs were not statistically significant. The present prospective study showed no statistically significant relationship between breastfeeding duration and the risk of wheeze or asthma in Japanese infants.

    ObjectiveTo study the risk factors for moderate and severe iron deifciency anemia (IDA) in infants aged 6-12 months, and to preliminarily investigate the effects of IDA on the neuromotor development and temperament characteristics of infants.MethodsA total of 326 infants aged 6-12 months with IDA were classiifed into three groups: mild IDA (n=176), moderate IDA (n=111), and severe IDA (n=39) according to the severity of anemia. The risk factors for moderate or severe IDA were investigated by multivariate logistic regression analysis. Three hundred and forty-six infants without IDA who showed matched age, sex, and other backgrounds were selected as the control group. The Gesell Development Diagnosis Scale was used to evaluate children’s mental development. The Temperament Scale for infants was used for evaluating children's temperament.ResultsThe univariate analysis showed that the severity of IDA was associated with sex, birth weight, gestational age, multiple birth, maternal anemia during pregnancy, and mother's lack of knowledge about IDA (P1;P1;P1,P1,P<0.05)。IDA组Gesell总发育商、大运动、适应行为、精细动作得分较对照组低(P<0.05)。IDA组难养型及中间偏难养型气质的比例较高(P<0.05)。IDA组活动水平、节律性、适应性、坚持性维度得分较对照组高(P<0.05)。结论早产、多胎、低出生体重、喂养方式、母亲孕期贫血及母亲缺乏IDA相关知识与6~12月龄婴儿IDA贫血程度相关。IDA患儿神经运动发育落后,消极气质类型居多,需加强对患儿心理行为问题的重视,指导家长选择恰当的喂养及教育方式。

    OBJECT Head trauma is the leading cause of death in abused children, particularly prior to the age of 2 years. An awareness of factors associated with this condition as well as with a higher risk of mortality is important to improve outcomes and prevent the occurrence of these events. The objective of this study was to evaluate outcomes and factors associated with poor outcomes in infants with diagnosed abusive head trauma (AHT). Patient characteristics, socioeconomic factors, and secondary conditions such as retinal bleeding, contusion, and fractures were considered. METHODS Data were obtained from the Healthcare Cost and Utilization Project of the Agency for Healthcare Research and Quality. From the Kids' Inpatient Database (KID) sample, the authors identified infants no older than 23 months who had been diagnosed with AHT in 2000, 2003, 2006, and 2009. All statistical analyses were conducted in SAS 9.2. Descriptive statistics were provided, and multivariate logistic regression models were applied to evaluate factors associated with mortality and nonroutine discharge. RESULTS A total of 5195 infants were analyzed in this study. Most infants (85.5%) had ages ranging between 0 and 11 months and were male (61.6%). Overall mortality was 10.8%, with a rate of 9.8% in the 0- to 11-month-old cohort and 16.5% in the 12- to 23-month-olds (p = 0.0003). The overall nonroutine discharge rate of 25.6% increased significantly from 23.3% to 39.0% with increasing age (0-11 vs 12-23 months of age, p older infants (12-23 vs 0-11 months, OR 1.81, 95% CI 1.18-2.77) with a secondary diagnosis of retinal bleeding (OR 2.85, 95% CI 2.02-4.00) or shaken baby syndrome (OR 2.09, 95% CI 1.48-2.94) had an increased risk of mortality; these factors were similarly associated with an increased odds of a nonroutine discharge. A higher income ($30,001-$35,000 vs $1-$24,999) was associated with a reduction in the odds of mortality (OR 0.46, 95% CI 0.29-0.72). In the subset of cases (1695 [32

    The discussions on noxious environmental factors concerning SIDS was a motive for systematically postmortal chemical-toxicological investigations on 54 SIDS-cases and 2 controlcases of the same age. Tissue levels of arsenic, lead, cadmium, mercury and pentachlorphenol as well as other organic noxes were measured in several organs. Furthermore COHb-concentrations were determined. Inspite of the wide scattering values the measured extreme levels as well as the arithmetic mean- and the median averages of As, Pb, Cd, Hg, PCP and COHb ranged in concentration sizes which - according to present knowledge - can't be supposed of toxic effects. It was observed that infants from an urban environment didn't show a higher degree of the examined noxes than infants from rural regions. Also there were neither differences between SIDS-cases and controls, nor correlations between often morphologically detected infections of the respiratory system, including laryngitis - and superior concentrations of these noxes in the organs of SIDS-cases.

Its detection are considered a key for the diagnostic as well as for the preventive and even curative strategies. For a long time, scientist considered those factors originated as a consecuence of large studies during the middle of the last century, with current validity up to our days. A simple classification spoke of them as traditionals. Further investigations described the so called new or emergents.factors that where joint together accordingly to their actions: coagulation factors, psicosocial, inflamatories and infectious. A recent classification, taking into account the type of impact, divided them into; causatives, predisposals and conditionals. Also, it was described a mechanism, the oxidative power, with consecuences over the endothelium, in the last part of the process. Before, another mechanism was described: the insulin resistance and the hiperinsulinism, bases for the Metabolic Syndrome, that includes a number of traditional risk factors.

    Background 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. Aim To investigate the relationship between psychosocial risks and communication delays in infants from underserved communities in South Africa. Setting Primary healthcare facilities in Tshwane district, South Africa. Methods 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. Results 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. Conclusion 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.

Anthropometric and socio-economic data were collected retrospectively from PMTCT registers (for HIV-EU infants), with HIV-U controls recruited at measles vaccination at public health facilities in Ethiopia. Growth was compared with regard to HIV exposure and socio-economic variables in multivariate regression analysis. The following growth measurements were found for 302 HIV-EU and 358 HIV-U infants at 9-12 months of age, respectively: mean weight-for-age z-score (WAZ) 0.04 and -0.21, p education (p education (p = 0.019). Lower LAZ was associated with male sex (p education (p education (p = 0.014). At 9-12 months of age, HIV-EU infants had non-inferior growth and higher mean WAZ than HIV-U controls. Poor growth development was associated with socio-economic factors. This suggests health benefits from PMTCT participation for infant growth. Similar interventions could be considered for Ethiopian infants, irrespective of HIV exposure, with a particular focus on children with poor socio-economic status.

    Full Text Available Background: We aimed to identify the risk factors for epilepsy in children. Materials and Methods: This case-control retrospective study was carried out in the pediatric neurology outpatient service of the Trivandrum Medical College. All children (1-12 years with epilepsy satisfying the selection criteria were included, after obtaining consent from parents. Those with single seizures or febrile seizures were excluded. Controls were children without epilepsy attending the same hospital. Parents were interviewed and clinical data were obtained from medical records. Statistical analysis included chi-square test, odds ratio (OR, and logistic regression. Results: There were 82 cases and 160 controls whose mean age was 6.9 + 3.6 and 5.2 + 3.1, years respectively. On univariate analysis, family history of epilepsy, prolonged labor, cyanosis at birth, delayed cry after birth, admission to newborn intensive care unit, presence of congenital malformations, neurocutaneous markers, incessant cry in the first week, delayed developmental milestones, meningitis, encephalitis, and head trauma were found to be significant. On logistic regression, family history of epilepsy (OR 4.7, newborn distress (OR 8.6, delayed developmental milestones (OR 12.6, and head trauma (OR 5.8 were found to be significant predictors. Infants who had history of newborn distress are likely to manifest epilepsy before 1 year if they are eventually going to have epilepsy (OR 3.4. Conclusion: Modifiable factors such as newborn distress and significant head trauma are significant risk factors for childhood epilepsy. Newborn distress is a risk factor for early-onset (<1 year age epilepsy.

    Background.  Database studies have identified that public health insurance status is associated with an increased risk of severe respiratory syncytial virus (RSV) disease in US infants. However, these studies did not adjust for the presence of other risk factors and did not evaluate the risk in preterm infants. Methods.  In this study, we evaluate the independent association between public insurance and severe RSV disease outcomes adjusting for other risk factors. The prospective, observational RSV Respiratory Events among Preterm Infants Outcomes and Risk Tracking (REPORT) study was conducted over 2 consecutive RSV seasons at 188 US clinical sites that enrolled preterm infants born at 32-35 wGA who had not received RSV immunoprophylaxis with palivizumab. Adjusted incidence rates per 100 infant-seasons of the RSV-associated endpoints of outpatient lower respiratory tract infection (LRI), emergency department (ED) visits, RSV hospitalizations (RSVHs), and intensive care unit admissions during peak RSV season (November-March) were compared for infants with private and public insurance. Results.  Of 1642 evaluable infants enrolled in the REPORT study, 50.1% had private insurance and 49.9% had public health insurance. Adjusted rates of RSV outpatient LRIs were similar; however, rates of ED visits (hazard ratio [HR], 2.04; 95% confidence interval [CI], 1.20-3.45) were higher for subjects with public insurance, with a similar but nonsignificant trend observed for hospitalization (HR, 1.61; 95% CI, .93-2.78). Conclusions.  Socioeconomic status, as evaluated by public versus private healthcare insurance, is a significant independent risk factor for ED use in US preterm infants and may contribute to increased RSVHs in this population.

METODOLOGÍA: Lactantes de ambos sexos em número de 788, fueron exhaustivamente estudiados en términos de: alimentación, crecimiento, ambiente físico y psicosocial. Se controlaron prospectivamente hasta los 12 meses de edad, momento en que se evaluó el desarrollo mental (MDI y motor (PDI a través de la escala de Bayley. A partir de las variables medidas se identificó 18 factores de riesgo, los que fueron dicotomizados (bajo y alto riesgo. RESULTADOS: Lactancia materna, temperamento del niño, inteligencia materna y estimulación en el hogar se asocian consistentemente con MDI y PDI. Luego de ajustar por covariables, la estimulación en el hogar persiste como factor significativo en la explicación de la variabilidad del MDI y PDI, en tanto que el sexo del niño se consolida como factor condicionante del desarrollo motor. El efecto acumulado de 7 o más factores de riesgo se asocia con una disminución significativa de los puntajes de desarrollo. La combinación de categorías de riesgo de temperamento infantil, inteligencia materna, rol del padre y estimulación en el hogar alcanza mejor predicción del desarrollo infantil que otras combinaciones puestas a prueba en este estudio.

    Background The risk of asthma, specifically in former late preterm infants, has not been well defined. Covariate imbalance and lack of controlling for this has led to inconsistent results in prior studies. Objective Determine the risk of asthma in former late preterm infants using a propensity score approach. Methods The study was a population-based birth cohort study. Study subjects were all children born in Rochester, Minnesota, between 1976 and 1982. Asthma status during the first seven years of life was assessed by applying predetermined criteria. The propensity score was formulated using 15 covariates by fitting a logistic regression model for late preterm birth versus term birth. We applied the propensity score method to match late preterm infants (34 0/7 to 36 6/7 weeks gestation) to term infants (37 0/7 to 40 6/7 weeks gestation) within a caliper of 0.2 standard deviation of logit of propensity score. Results Of the eligible 7,040 infants, 5,915 children had complete data. Before propensity score matching, late preterm infants had a higher risk of asthma (20 of 262, 7.6%) compared to full-term infants (272 of 5,653, 4.8%)(p=0.039). There was significant covariate imbalance between comparison groups. After matching with propensity scores, we found that former late preterm infants had a similar risk of asthma to the matched full-term infants (6.6% vs. 7.7%, respectively, p=0.61), and the result were consistent with covariate-adjustment, Cox regression models controlling for significant covariates (p=0.57). Conclusion A late preterm birth history is not independently associated with childhood asthma, as the reported risk of asthma among former late preterm infants appears to be due to covariate imbalance.

    Objective To investigate the risk factors of prognosis of neonatal respiratory failure in late preterm and full-term infants.Methods Sixty-eight neonates with respiratory failure hospitalized in neonatal intensive care unit (NICU) were divided into late preterm infants group (n =34) and full-term infants group (n =34),the general clinical characteristics,perinatal parameters,treatment process of respiratory failure,main disease diagnosis and prognosis evaluation were compared between these two groups.Besides,the clinical parameters and respiratory parameters were compared between favorable prognosis group and unfavorable prognosis group.Results The average birth weight in late preterm infants group was significantly lower than that in full-term infants group (P < 0.01),and the proportion of infants with low body weight in late preterm infants group was significantly higher than that in full-term infants group (P <0.05).However,there was no significant difference in the gender constituent ratio,age at NICU admission and proportion of infants small for gestational age between two groups (P > 0.05).There was no significant difference in the healthy status and other perinatal parameters between late preterm infants group and full-term infants group (P > 0.05).Apnea was only found in late preterm infants group,and NO inhalation treatment and high frequency ventilation were only adopted in full-term infants group,while there was no significant difference in the main disease diagnosis,respiratory treatment modality and prognosis between two groups (P > 0.05).The proportion of infants small for gestational age in favorable prognosis group was significantly lower than that in unfavorable prognosis group (P < 0.05),while the Caesarean section rate in favorable prognosis group was significantly higher than that in unfavorable prognosis group (P < 0.05).Conclusion Relationship between gestational age and body weight of neonates with respiratory failure and way of

  6. Risk factors for Down syndrome.

    Coppedè, Fabio

    2016-12-01

    Down syndrome (DS) originates, in most of the cases (95 %), from a full trisomy of chromosome 21. The remaining cases are due to either mosaicism for chromosome 21 or the inheritance of a structural rearrangement leading to partial trisomy of the majority of its content. Full trisomy 21 and mosaicism are not inherited, but originate from errors in cell divisions during the development of the egg, sperm or embryo. In addition, full trisomy for chromosome 21 should be further divided into cases of maternal origin, the majority, and cases of paternal origin, less than 10 %. Among cases of maternal origin, a further stratification should be performed into errors that have occurred or originated during the first meiotic division in the maternal grandmother's body and errors that occurred later in life during the second maternal meiotic division. This complex scenario suggests that our understanding of the risk factors for trisomy 21 should take into account the above stratification as it reflects different individuals and generations in which the first error has occurred. Unfortunately, most of the available literature is focused on maternal risk factors, and the only certain risk factors for the birth of a child with DS are advanced maternal age at conception and recombination errors, even though the molecular mechanisms leading to chromosome 21 nondisjunction are still a matter of debate. This article critically reviews the hypotheses and the risk factors which have been suggested to contribute to the birth of a child with DS, including folate metabolism, dietary, lifestyle, environmental, occupational, genetic and epigenetic factors, with focus on maternal and paternal risk factors, and taking into account the possible contribution of the maternal grandmother and that of the developing trisomic embryo, in a complex scenario depicting the birth of a child with DS as the result of complex gene-environment interactions and selection processes involving different

    Full Text Available Objective: to describe predictive factors for severity of neonataljaundice in newborn infants treated at the University Neonatal Clinic,highlighting maternal, obstetric and neonatal factors. Methods: Acohort retrospective study by means of review of medical charts todefine risk factors associated with moderate and severe jaundice.The cohort consisted of newborns diagnosed with indirect neonatalhyperbilirubinemia and submitted to phototherapy. Risk was classifiedas maternal, prenatal, obstetric and neonatal factors; risk estimationwas based on the odds ratio (95% confidence interval; a bi-variantmultivariate regression logistic analysis was applied to variables forp < 0.1. Results: Of 818 babies born during the studied period, 94(11% had jaundice prior to hospital discharge. Phototherapy was usedon 69 (73% patients. Predictive factors for severity were multiparity;prolonged rupture of membranes, dystocia, cephalohematoma, a lowApgar score, prematurity and small-for-date babies. Following birth,breastfeeding, sepsis, Rh incompatibility, and jaundice presentingbefore the third day of life were associated with an increased risk ofhyperbilirubinemia and the need for therapy. Conclusion: Other thanthose characteristics that are singly associated with phototherapy,we concluded that multiparity, presumed neonatal asphyxia, low birthweight and infection are the main predictive factors leading to moderateand severe jaundice in newborn infants in our neonatal unit.

    Full Text Available Substantial progress has been made in reducing childhood mortality worldwide from 1990-2015 (Millennium Development Goal, target 4. Achieving target goals on this however remains a challenge in Sub-Saharan Africa. Kenya's infant mortality rates are higher than the global average and are more pronounced in urban areas as compared to rural areas. Only limited knowledge exists about the differences in individual level risk factors for infant death among rural, non-slum urban, and slum areas in Kenya. Therefore, this paper aims at 1 assess individual and socio-ecological risk factors for infant death in Kenya, and at 2 identify whether living in rural, non-slum urban, or slum areas moderated individual or socio-ecological risk factors for infant death in Kenya.We used a cross-sectional study design based on the most recent Kenya Population and Housing Census of 2009 and extracted the records of all females who had their last child born in 12 months preceding the survey (N = 1,120,960. Multivariable regression analyses were used to identify risk factors that accounted for the risk of dying before the age of one at the individual level in Kenya. Place of residence (rural, non-slum urban, slum was used as an interaction term to account for moderating effects in individual and socio-ecological risk factors.Individual characteristics of mothers and children (older age, less previously born children that died, better education, girl infants and household contexts (better structural quality of housing, improved water and sanitation, married household head were associated with lower risk for infant death in Kenya. Living in non-slum urban areas was associated with significantly lower infant death as compared to living in rural or slum areas, when all predictors were held at their reference levels. Moreover, place of residence was significantly moderating individual level predictors: As compared to rural areas, living in urban areas was a protective factor

    Of 5,500 newborn infants whose family histories were screened, 900 were found to have anamnestic risk. Cord-blood IgE was evaluable in 4,677 of these newborns, of which 394 had levels > or = 1 IU/mL; 84 infants had both anamnestic risk and elevated cord-blood IgE levels. Parents of infants with anamnestic risk were informed of their child's risk of atopy. Additionally, for 391 infants at two of the three participating hospitals, a preventive diet was prescribed that recommended breastfeeding for the first 6 months of life, with maternal diet restricted to no more than 200 dL of cow milk per day, no more than one egg per week, and no tomato, fish, shellfish, nuts, or foods allergenic to the mother. Only soy formula was recommended, and introduction of solid foods was also carefully prescribed. Furthermore, doctors recommended against exposure to tobacco smoke, animal allergens, and early entrance into daycare. Evaluable infants whose parents complied with the prescribed diet were found to have a lower incidence of atopy during the first year of life (13.3%, n = 158) than infants whose parents had ignored the prescribed diet (54.7%, n = 86) or infants whose parents were offered no dietary recommendations (28.9%, n = 218). Differences between the compliant group and the two groups with unrestricted diets were significant, indicating that this prescribed diet may protect against or delay onset of food allergies during the first year of life.

    Full Text Available INTRODUCTION: Cerebral palsy (CP is a group of permanent movement disorders that appear in early childhood. Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance, and posture. Most often the problems occur during pregnancy; however, they may also occur during childbirth, or shortly after birth. Often the cause is unknown. AIM: To study the different antenatal maternal risk factors associated with cerebral palsy in the study group. MATERIA LS AND METHODS: Retrospective study was done to assess possible associated antenatal risk factors for cerebral palsy. Mothers of 100 cerebral palsy children were selected who are treated in Rani Chandramani Devi Hospital, a Government hospital in Visakhapa tn am, Andhra Pradesh State, India , from 2012 to 2014 and 100 controls, mothers of normal children were studied. Detailed antenatal history was obtained from the mothers of the children in both affected and control group. RESULTS: From the data, we conclude that the association of maternal anaemia with cerebral palsy is 7.3 times higher; association of maternal hypertension with cerebral palsy is 6.6 time higher, association with Pre - eclampsia is 6 times higher; association with Eclampsia is 8.6 times higher ; with antepartum haemorrhage, the association is 8.6 times higher and association of multiple pregnancy with cerebral palsy is 4.8 times higher than with controls. CONCLUSION: From this study of the role of antenatal risk factors, in the occurrence of cer ebral palsy in children it is concluded that the most common risk factor associated with cerebral palsy is the maternal anaemia and the other important risk factors associated being hypertension, pre eclampsia, eclampsia, antepartum haemorrhage and multipl e births.

    Full Text Available Background Retinopathy of prematurity (ROP is the main cause of visual impairment in premature infants. Due to advances in neonatal care, the increased survival of extremely low birth weight (ELBW infants in recent years has produced a population of infants at very high risk of ROP. Objective The aims of this study were to determine the prevalence and potential risk factors for ROP. Methods This retrospective study was conducted at the Neonatalogy Ward, Cipto Mangunkusumo Hospital, from January 2005 to August 2010. We included all premature infants of gestational age (GA < 37 weeks, body weight (BW not exceeding 2000 grams, as well as those who had eye examinations and complete medical records. Risk factors such as GA, BW, duration of oxygen (O2 therapy, sepsis, and red blood cell (RBC transfusion were analyzed using the Chi-square and logistic regression tests. Pediatric ophthalmologists had performed eye examinations on all infants. ROP was graded according to the International Classification of ROP. Results The prevalence of ROP and of stage 3 or greater ROP was 11.9% and 4.8% of all subjects, respectively. Body weight, GA, duration of O2 therapy, and sepsis were found to be associated with the development of ROP. However, stepwise logistic regression analysis revealed that only BW of ≤ 1000 g [odds ratio (OR 10.88; 95% CI 3.09 to 38.31; P < 0.000], O2 therapy ≥ 7 days (OR 5.56; 95% CI 1.86 to 16.58; P < 0.0001, and GA of ≤ 28 weeks (OR 4.26; 95% CI 1.15 to 15.81; P = 0.030 were statistically significant risk factors for ROP. The equation obtained was y = -4.092 + 2.388 (BW + 1.451 (GA + 1.716 (duration of O2 therapy. The model showed good calibration (a non-significant Hosmer-Llemeshow test; P = 0.816 and discriminative ability. The area under the curve (AUC value was 92.2% (95% CI 0.867 to 0.976; P < 0.0001.

    Full Text Available Purpose: The main object of the present study is to assess neuromotor development of high-risk infants by using three tests, and to determine inter-test concordance and the feasibility of these tests. Materials and Methods: One-hundred and nine patients aged between 0 and 6 months and identified as "high-risk infant" according to the Kliegman′s criteria were enrolled to the study. Three different tests were used to assess neuromotor development of the patients: Bayley scales of infant development-II (BSID-II, Alberta infant motor scale (AIMS, and Milani Comparetti Motor Development Screening Test (MCMDST. Results: Correlation analysis was performed between pure scores of BSID-II motor scale and total scores of AIMS. These two tests were highly correlated (r:0.92. Moderate concordance was found between BSID-II and AIMS (k:0.35. Slight concordance was found between BSID-II and MCMDST; and the concordance was slight again for AIMS and MCMDST (k:0.11 and k:0.16, respectively too. Conclusion: AIMS has a high correlation and consistency with BSID-II and can be used with routine neurological examination as it is based on observations, has few items, and requires less time to complete.

    Cranial MRI scans were performed in seventy-five infants determined to be at risk for neurological impairment in future. Thirty-four infants demonstrated a total of 51 lesions consistent with hypoxic ischemic encephalopathy (HIE), including periventricular leukomalacia with cysts (cystic PVL, n=4), PVL without cysts (linear PVL, n=15), intracerebral hemorrhage (ICH, n=7), intraventricular hemorrhage (IVH, n=4), and ventriculomegaly (n=21). Diagnoses by ultrasonography (US) were compared with those by MRI in all infants, respectively. US findings almost agreed with those of MRI except ventriculomegaly. PVL and IVH were seen most often in preterm infants, ICH occurred in full term infants. All infants of cystic PVL and 10 infants of linear PVL (67%) had developmental abnormalities. Thirty-nine infants had once or twice sequential MRI scans. In all infants with PVL, the findings of periventricular hyperintensity, volume loss of white matter and myelination delay were more evident at sequential MRI scans. These findings were correlated with the severity of developmental abnormalities. This study suggests that sequential MRI provides a more reliable prediction of neurological impairment. (author)

    Fibroblast growth factor-23 (FGF23), a phosphate(Phos)-regulating hormone, is abnormally elevated in hypophosphataemic syndromes and an elevated FGF23 is a predictor of mortality in kidney disease. Recent findings suggest iron deficiency as a potential mediator of FGF23 expression and murine studies have shown in utero effects of maternal iron deficiency on offspring FGF23 and phosphate metabolism. Our aim was to investigate the impact of maternal iron status on infant FGF23 and mineral metabolites over the first 2years of life. Infants born to mothers with normal (NIn=25,) and low (LIn=25) iron status during pregnancy, from a mother-infant trial (ISRCTN49285450) in rural Gambia, West Africa, had blood and plasma samples analysed at 12, 24, 52, 78 and 104weeks (wk) of age. Circulating intact-FGF23 (I-FGF23), Phos, total alkaline phosphatase (TALP) and haemoglobin (Hb) decreased and estimated glomerular filtration rate increased over time [all P≤0.0001)]. C-terminal-FGF23 (C-FGF23) and TALP were significantly higher in LI compared with NI, from 52wk for C-FGF23 [Beta coefficient (SE) 18.1 (0.04) %, P=0.04] and from 24wk for TALP [44.7 (29.6) U/L, P=0.04]. Infant Hb was the strongest negative predictor of C-FGF23 concentration [-21% (4%) RU/mL, P≤0.0001], Phos was the strongest positive predictor of I-FGF23 [32.0(3.9) pg/mL, P≤0.0001] and I-FGF23 did not predict C-FGF23 over time [-0.5% (0.5%), P=0.3]. In conclusion, this study suggests that poor maternal iron status is associated with a higher infant C-FGF23 and TALP but similar I-FGF23 concentrations in infants and young children. These findings further highlight the likely public health importance of preventing iron deficiency during pregnancy. Whether or not children who are born to iron deficient mothers have persistently high concentrations of these metabolites and are more likely to be at risk of impaired bone development and pre-disposed to rickets requires further research.

    Currently, there are no set standards or quantitative guidelines available in the U.S. for arsenic levels in rice cereal, one of the most common first solid foods for infants. The objective of this study was to evaluate whether the detected levels of inorganic arsenic (As(i)) in rice cereal in the U.S. market are safe for consumption by infants and toddlers. A risk assessment was conducted based on literature reviews of the reported As(i) in rice cereal from the U.S. Food and Drug Administration's (FDA) survey and the recommended daily intake of rice cereal by body weight, for infants and toddlers between four and 24 months old. As a part of risk management, a maximum contaminant level (MCL) for Asi in rice cereal was computed considering overall exposure sources including drinking water, infant formula, and other infant solid foods. Hazard quotients (HQs) for acute and chronic exposures were calculated based on the U.S. Agency for Toxic Substances and Disease Registry's (ATSDR) Minimal Risk Level (MRL)(acute) (5.0 × 10(-3) mg/kg/day) and MRL(chronic) (3.0 × 10(-4) mg/kg/day). A cancer slope or potency factor of 1.5 mg/kg/day was used to predict an incremental lifetime cancer risk (ILCR). Exposure assessment showed that the largest source of As(i) for infants and toddlers between four and 24 months old was rice cereal (55%), followed by other infant solid food (19%), and drinking water (18%). Infant formula was the smallest source of As(i) for babies (9%) at the 50th percentile based on Monte Carlo simulations. While HQ(acute) were consistently below 1.0, HQ(chronic) at the 50 and 75th percentiles exceeded 1.0 for both rice cereal and total sources. ILCR ranged from 10(-6) (50th) to 10(-5) (75th percentile). MCLs for As(i) in rice cereal ranged from 0.0 (chronic) to 0.4 mg/kg (acute exposures).

    Abusive head trauma (AHT) is an important cause of morbidity in infants. Identifying which well-appearing infants are at risk for AHT and need neuroimaging is challenging, and concern about radiation exposure limits the use of head CT. Availability of an MRI protocol that is highly sensitive for intracranial hemorrhage would allow for AHT screening of well-appearing infants without exposing them to radiation. To develop a screening MRI protocol to identify intracranial hemorrhage in well-appearing infants at risk for AHT. Infants enrolled in a parent study of well-appearing infants at increased risk for AHT were eligible for the current study if they underwent both head CT and conventional brain MRI. A derivation cohort of nine infants with AHT was used to identify sequences that provided the highest sensitivity for intracranial hemorrhage. A validation cohort of 78 infants including both controls with normal neuroimaging and cases with AHT was used to evaluate the accuracy of the selected sequences. Three pulse sequences - axial T2, axial gradient recalled echo (GRE) and coronal T1-W inversion recovery - were 100% sensitive for intracranial hemorrhage in the derivation cohort. The same sequences were 100% sensitive (25/25) and 83% specific (44/53) for intracranial hemorrhage in the validation cohort. A screening MRI protocol including axial T2, axial GRE and coronal T1-W inversion recovery sequences is highly sensitive for intracranial hemorrhage and may be useful as a screening tool to differentiate well-appearing infants at risk for AHT who should undergo head CT from those who can safely be discharged without head CT. Additional research is needed to evaluate the feasibility of this approach in clinical practice. (orig.)

    In the field of autism research, recent work has been devoted to studying both behavioral and neural markers that may aide in early identification of autism spectrum disorder (ASD). These studies have often tested infants who have a significant family history of autism spectrum disorder, given the increased prevalence observed among such infants. In the present study we tested infants at high- and low-risk for ASD (based on having an older sibling diagnosed with the disorder or not) at 6- and 12-months-of-age. We computed intrahemispheric linear coherence between anterior and posterior sites as a measure of neural functional connectivity derived from electroencephalography while the infants were listening to speech sounds. We found that by 12-months-of-age infants at risk for ASD showed reduced functional connectivity compared to low risk infants. Moreover, by 12-months-of-age infants later diagnosed with ASD showed reduced functional connectivity, compared to both infants at low risk for the disorder and infants at high risk who were not later diagnosed with ASD. Significant differences in functional connectivity were also found between low-risk infants and high-risk infants who did not go onto develop ASD. These results demonstrate that reduced functional connectivity appears to be related to genetic vulnerability for ASD. Moreover, they provide further evidence that ASD is broadly characterized by differences in neural integration that emerge during the first year of life.

  13. Neurodevelopmental risk factors in schizophrenia

    Lobato M.I.

    2001-01-01

    Full Text Available The authors review environmental and neurodevelopmental risk factors for schizophrenic disorders, with emphasis on minor physical anomalies, particularly craniofacial anomalies and dermatoglyphic variations. The high prevalence of these anomalies among schizophrenic subjects supports the neurodevelopmental theory of the etiology of schizophrenia, since they suggest either genetically or epigenetically controlled faulty embryonic development of structures of ectodermal origin like brain and skin. This may disturb neurodevelopment that in turn may cause these subjects to be at increased risk for the development of schizophrenia and related disorders. The precise confirmation of this theory, at least in some cases, will provide further understanding of these illnesses, allowing easy and inexpensive identification of subjects at risk and providing guidelines for the development of new pharmacological interventions for early treatment and even for primary prevention of the illness.

But too little is known about the association between disability and psychopathology. The aim of this article is to discuss developmental...... psychopathological models that conceptualize the connection between childhood disability and psychopathology. Empirical studies of psychopathology among children with a congenital hearing impairment and children with cerebral palsy will be reviewed, representing in-depth examples of association between disability...... and psychopathology. Both a congenital hearing impairment and cerebral palsy were found to be dominating risk factors for all types of psychopathology, but no relationship was identified between degree of disability and risk of psychopathology.

    2010-01-01

    Full Text Available Introduction. This article summarizes the contribution of epidemiology to the understanding of childhood asthma. The first task in epidemiology is to determine prevalence and incidence of any disease. Prevalence. Epidemiological investigations are aimed at evaluating hypotheses about causes of disease by defining demographic characteristics of a certain population as well as by determining possible effects of environmental factors. In spite of some limitations, data obtained by epidemiological investigations have been valuable in confirming both the increasing incidence of asthma and the differences in prevalence in certain population groups. The observance of this phenomenon has led to much speculation and a lot of attempts to identify the reasons behind the rising prevalence. Risk factors. Epidemiological studies have identified risk factors for the development of childhood asthma and provided insight into natural history of disease and prognosis. Factors ranging from increased numbers of immunizations to increased air pollution have been suggested, but subsequent analysis has failed to provide the supporting evidence to implicate most of these possibilities. The concept known as the hygiene hypothesis has gained some support from epidemiological studies. Conclusion. The development of asthma as well as its severity are affected by numerous factors and their interactions can be explained by the heterogeneous nature of this disease.

    Familial history risk factors in relation to autism were examined in a cohort of 164 autistic children referred to The Autism Center at New Jersey Medical School-University of Medicine and Dentistry of New Jersey, Newark, over a 2-year period (2001-2003). Information related to familial history was obtained from each family and reviewed by a clinician. It is shown that these families carry a higher overall burden of psychiatric and developmental illnesses compared to reported national levels. These families also carry a relatively high incidence of medical disorders, independently of developmental and psychiatric disorders. This work supports the underlying presence of genetic factors in the etiology of autism.

    Full Text Available Preterm birth is associated with increased risks of neurological and motor impairments such as cerebral palsy. The risks are highest in those born at the lowest gestations. Early identification of those most at risk is challenging meaning that a critical window of opportunity to improve outcomes through therapy-based interventions may be missed. Clinically, the assessment of spontaneous general movements is an important tool which can be used for the prediction of movement impairments in high risk infants.Movement recognition aims to capture and analyze relevant limb movements through computerized approaches focusing on continuous, objective, and quantitative assessment. Different methods of recording and analyzing infant movements have recently been explored in high risk infants. These range from camera-based solutions to body-worn miniaturized movement sensors used to record continuous time-series data that represent the dynamics of limb movements. Various machine learning methods have been developed and applied to the analysis of the recorded movement data. This analysis has focused on the detection and classification of atypical spontaneous general movements. This paper aims to identify recent translational studies using movement recognition technology as a method of assessing movement in high risk infants. The application of this technology within pediatric practice represents a growing area of inter-disciplinary collaboration which may lead to a greater understanding of the development of the nervous system in infants at high risk of motor impairment.

  18. Environmental risk factors for autism

    2011-01-01

    Autism is a devastating childhood condition that has emerged as an increasing social concern just as it has increased in prevalence in recent decades. Autism and the broader category of autism spectrum disorders are among the increasingly seen examples in which there is a fetal basis for later disease or disorder. Environmental, genetic, and epigenetic factors all play a role in determining the risk of autism and some of these effects appear to be transgenerational. Identification of the most...

    Risk factors of obstetrical brachial plexus palsy include: (1) large birth weight, (2) shoulder dystocia and prolonged second stage of labour, (3) instrumental vaginal delivery (forceps delivery, vacuum extraction), (4) diabetes mellitus and mother's obesity, (5) breech presentation, (6) delivery and infant with obstetrical brachial plexus palsy in antecedent delivery. The purpose was analysis of the classical risk factors for brachial plexus palsy based on our own clinical material. Clinical material consists of 83 children with obstetrical brachial plexus palsy treated at the Department of Trauma and Hand Surgery (surgically--54, conservatively--29). Control group consists of 56 healthy newborns. Data recorded included: birth weight, body length, head and chest circumference, Apgar test at 1 min., type of brachial palsy and side affected, type of birth, presentation, duration of delivery (II stage), age of mother, mother's diseases, parity. The infants treated surgically have had a significantly higher birth weight, body height, head and chest circumference, in compression with control group and group treated conservatively. The differences were statistically important. Shoulder dystocia occurred in 32.9% of all vaginal delivery. Instrumental vaginal delivery was observed in 11.3% and breech presentation in 4.9% cases. There were no incidences of obstetrical brachial plexus palsy recurrence. Diabetes mellitus and mother's obesity was found in 3 cases. (1) Fetal macrosomia is the important risk factor of the obstetrical brachial plexus palsy. (2) Obstetrical brachial plexus palsy may occur also in the absence of the classical risk factors.

    Full Text Available Background. A follow-up program for high risk infants was initiated in Alzahra Maternity Hospital in Tabriz city, Iran, in 2013. The aim of this paper is to give a brief report of the program. Material and Methods. Two groups of high risk neonates were studied. The first group comprising 509 infants received services in Alzahra Maternity Hospital implemented by the follow-up program. This included a full package for family to look after high risk infant and periodic clinical evaluation at two and four weeks after birth and then two, three, four, five, and six months later again. The second group including 131 infants in Taleqani Maternity Hospital received routine services after birth with no specific follow-up care. Results. Some anthropometric indices showed a significant improvement in the intervention hospital compared to control group. These included the following: head circumference at first and second months; weight in the first, fourth, fifth, and sixth months; and height in sixth month only. Clinical evaluation of infants showed an improvement for some of the medical conditions. Conclusion. Follow-up care program for a minimum of six months after discharge from maternity hospitals may help to avoid adverse and life threatening consequences in high risk infants.

    Infants' advances in locomotion relate to advances in communicative development. However, little is known about these relations in infants at risk for delays in these domains and whether they may extend to earlier achievements in gross motor development in infancy. We examined whether advances in sitting and prone locomotion are related to communicative development in infants who have an older sibling with autism spectrum disorder (ASD) and are at risk for motor and communication delays (heightened-risk; HR). We conducted a longitudinal study with 37 HR infants who did not receive an ASD diagnosis at 36 months. Infants were observed monthly between the ages of 5 and 14 months. We assessed gross motor development using the Alberta Infant Motor Scales (AIMS) and recorded ages of onset of verbal and nonverbal communicative behaviors. Results indicated increased presence of early gross motor delay from 5 to 10 months. In addition, there were positive relations between sitting and gesture and babble onset and between prone development and gesture onset. Thus, links between gross motor development and communication extend to at-risk development and provide a starting point for future research on potential cascading consequences of motor advances on communication development.

    Background Infant mortality has decreased in Brazil, but remains high as compared to that of other developing countries. In 2010, the Rio Grande do Sul state had the lowest infant mortality rate in Brazil. However, the municipality of Novo Hamburgo had the highest infant mortality rate in the Porto Alegre metropolitan region. Objective To describe the causes of infant mortality in the municipality of Novo Hamburgo from 2007 to 2010, identifying which causes were related to heart diseases and if they were diagnosed in the prenatal period, and to assess the access to healthcare services. Methods This study assessed infants of the municipality of Novo Hamburgo, who died, and whose data were collected from the infant death investigation records. Results Of the 157 deaths in that period, 35.3% were reducible through diagnosis and early treatment, 25% were reducible through partnership with other sectors, 19.2% were non-preventable, 11.5% were reducible by means of appropriate pregnancy monitoring, 5.1% were reducible through appropriate delivery care, and 3.8% were ill defined. The major cause of death related to heart disease (13.4%), which was significantly associated with the variables ‘age at death’, ‘gestational age’ and ‘birth weight’. Regarding access to healthcare services, 60.9% of the pregnant women had a maximum of six prenatal visits. Conclusion It is mandatory to enhance prenatal care and newborn care at hospitals and basic healthcare units to prevent infant mortality. PMID:25993588

    This study compared the expression of BDNF (proBDNF and rhBDNF forms) and its receptor TrkB, in the medulla of sudden infant death syndrome (SIDS) infants and infants who died from known causes (non-SIDS). This study also evaluated these markers in association with SIDS clinical risk factors including, sleep position, cigarette smoke exposure and gender. Brainstem tissue was immunohistochemically stained and quantitative analyses were made for eight nuclei of the caudal and rostral medulla. Compared to non-SIDS, SIDS infants had lower rhBDNF in the caudal nucleus of the solitary tract and higher TrkB in the caudal dorsal motor nucleus of the vagus. Within the SIDS cohort, prone sleep position was associated with lower rhBDNF in the caudal arcuate nucleus, and cigarette smoke exposure was associated with lower rhBDNF and TrkB in the inferior olivary nucleus. Abnormal expression of BDNF and TrkB suggests that neuroprotective functions of the BDNF/TrkB system may be reduced in respiratory-related nuclei of SIDS infants.

    Understanding of parent anxiety and its effect on infant postoperative pain is limited. We sought to identify psychological factors associated with preoperative anxiety for parents of infants and toddlers undergoing elective surgery and to determine whether parent anxiety is associated with child postoperative pain. This was a prospective cohort study of consecutively eligible patients aged ≤18 months undergoing craniofacial surgery and their parents. Preoperative parent assessment included anxiety, coping, parent health locus of control, and self-efficacy. Postoperative inpatient child pain scores and medication use were collected. Analyses included hierarchical multivariable logistic and linear regression models. Parents (n = 71, 90% female) of young children (mean age 6.6 months) undergoing cleft lip or palate (n = 59) or cranial vault repair (n = 13) were enrolled. Maladaptive coping (odds ratio 1.3; 95% confidence interval, 1.1-1.6), low parent self-efficacy (odds ratio 2.4; 95% confidence interval, 1.3-4.5), and external locus of control (odds ratio 1.74; 95% confidence interval, 1.1-2.9) were independently associated with high parental anxiety. The adjusted odds of moderate/severe parent anxiety was 3.6 (95% confidence interval, 1.5-9.1) higher with each SD increase in maladaptive coping. High parental anxiety was correlated with significantly higher hospital mean child pain scores (1.87 points on 0-10 scale; 95% confidence interval, 0.42-3.70; P = .045). Coping and self-efficacy are modifiable factors that contribute to parent anxiety before and during hospitalization and may be targets for intervention. Infants and toddlers undergoing elective craniofacial surgery with highly anxious parents may be at greater risk for higher postoperative pain.

    Full Text Available Background: Retinopathy of prematurity (ROP is a serious complication of prematurity treatment and can lead to blindness unless recognized and treated early. Objective: The objective was to estimate the prevalence of ROP in preterm infants in the Neonatal Intensive Care Unit (NICU, to identify the risk factors which predispose to ROP, and to assess the outcome of these cases. Materials and Methods: A ROP prospective screening survey was performed enrolling all prematures admitted to the NICU from January 2009 to December 2010, with a gestational age of 32 weeks or less at birth and a birth weight of 1500 g or less. Infants whose gestational age was >32 weeks or birth weight was >1500 g were included if they were exposed to oxygen therapy for more than 7 days. A total of 172 infants (84 males and 88 females had retinal evaluation by indirect ophthalmoscopy from the fourth postnatal week and followed up periodically. Perinatal risk factors for ROP were assessed using univariate and multivariate analysis. Infants who progressed to stage 3 ROP were given laser therapy. Results: Out of the studied 172 infants, 33 infants (19.2% developed ROP in one or both eyes; 18 (54.5% cases stage 1, 9 (27.3% cases stage 2, and 6 (18.2% cases stage 3. None of the studied neonates presented ROP at stages 4 or 5. The six cases diagnosed as ROP stage 3 underwent laser ablative therapy. Univariate analysis showed that there was a significant relationship between the occurrence of ROP and gestational age (P = 0.000, sepsis (P = 0.004, oxygen therapy (P = 0.018, and frequency of blood transfusions (P = 0.030. However, an insignificant relationship was found between the occurrence of ROP and sex, mode of delivery, birth weight, respiratory distress syndrome, patent ductus arteriosus, intraventricular hemorrhage, hypotension, phototherapy, duration of oxygen therapy, mechanical ventilation, and CPAP (all P > 0.05.

    Infant sleep safety is a primary concern of parents. Infant sleep locations vary around the world. This pilot study investigated the decision factors, fears, and safety strategies reported by parents internationally. participants (n=49) recruited online from 10 countries completed an anonymous Internet survey in English and submitted a picture of the infant's primary nighttime sleep location. Pictures were coded into 'shared' (29%) or 'separate' (71%) sleep surfaces. primary decision factors about infant sleep location were safety, comfort, family sleep quality, and overall ease. Parents maximized safety by providing a clear sleep surface, no blankets, no toys, sleep sack use, and a firm mattress. Different worries and fears emerged depending on the sleep surface. differences in the specific worries and strategies used by parents when deciding whether to share or not share a sleep surface with an infant may be used to tailor future interventions.

    Half of the 10 million children who die annually in the world are from Sub-Saharan Africa (SSA). The reasons are known, but lack of will and resources avoid the development of sustainable policies. Associated factors to the high infant mortality rate (IMR) in SSA have been investigated in this research. An ecological multi-group study was designed comparing rates within SSA. The dependent variable is the IMR and health services, economic and development indicators are the independent variables. Information and data sources were WHO, World Bank, UNICEF and UNDP (1997-2007). IMR mean value is 92.2 (per 1000 live births) and a relationship with several of the factors could be observed. In the bi-variate analysis direct relationship was observed with maternal mortality rate and an inverse relationship was observed with prenatal care coverage, births assisted by skilled health personnel, gross national income per capita, per capita government expenditure on health, social security expenditure, adult literacy rate, net primary school enrolment rate, population with access to safe drinking water (in urban and rural areas) and with population with access to basic sanitation in rural areas. In the multi-variate analysis IMR had an inverse relationship with children under 5 years with diarrhoea who receive oral re-hydration, with social security expenditure as percentage of general government expenditure on health and with per capita government expenditure on health. The situation in SSA would change if their inhabitants received education and information to demand more equitable polices and better investments from their governments.

  14. Disclosure Risk from Factor Scores

    Full Text Available Remote access can be a powerful tool for providing data access for external researchers. Since the microdata never leave the secure environment of the data-providing agency, alterations of the microdata can be kept to a minimum. Nevertheless, remote access is not free from risk. Many statistical analyses that do not seem to provide disclosive information at first sight can be used by sophisticated intruders to reveal sensitive information. For this reason the list of allowed queries is usually restricted in a remote setting. However, it is not always easy to identify problematic queries. We therefore strongly support the argument that has been made by other authors: that all queries should be monitored carefully and that any microlevel information should always be withheld. As an illustrative example, we use factor score analysis, for which the output of interest - the factor loading of the variables - seems to be unproblematic. However, as we show in the article, the individual factor scores that are usually returned as part of the output can be used to reveal sensitive information. Our empirical evaluations based on a German establishment survey emphasize that this risk is far from a purely theoretical problem.

    In a population‐based case‐control study in California of 228 infants, we investigated 75 genetic variants in 20 genes and risk of gastroschisis with regard to maternal age, race/ethnicity, vitamin use, and smoking exposure. We hypothesized that genes related to vascular compromise may interact with environmental factors to affect the risk of gastroschisis. Haplotypes were constructed for 75 gene variants using the HaploView program. Risk for gastroschisis associated with each gene variant was calculated for both the homozygotes and the heterozygotes, with the homozygous wildtypes as the referent. Risks were estimated as odds ratios (ORs) with 95% confidence intervals (CIs) by logistic regression. We found 11 gene variants with increased risk and four variants with decreased risk of gastroschisis for heterozygous (ORh) or homozygous variants (ORv) genotypes. These included NOS3 (rs1036145) ORh = 0.4 (95% CI: 0.2–0.7); NOS3 (rs10277237) ORv = 2.7 (95% CI: 1.3–6.0); ADD1 (rs12503220) ORh = 2.9 (95% CI: 1.6–5.4), GNB3 (rs5443) ORh = 0.2 (95% CI: 0.1–0.5), ORv = 0.4 (95% CI: 0.2–0.9); ICAM1 (rs281428) ORv = 6.9 (95% CI: 2.1–22.9), ICAM1 (rs3093030) ORv = 2.6 (95% CI: 1.2–5.6); ICAM4 (rs281438) ORv = 4.9 (95% CI: 1.4–16.6), ICAM5 (rs281417) ORh = 2.1 (95% CI: 1.1–4.1), ORv = 4.8 (95% CI: 1.7–13.6); ICAM5 (rs281440) ORh = 23.7 (95% CI: 5.5–102.5), ORv = 20.6 (95% CI: 3.4–124.3); ICAM5 (rs2075741) ORv = 2.2 (95% CI: 1.1–4.4); NAT1 ORv = 0.3 (95% CI: 0.1–0.9). There were additional associations between several gene variants and gastroschisis among women aged 20–24 and among mothers with and without vitamin use. NOS3, ADD1, ICAM1, ICAM4, and ICAM5 warrant further investigation in additional populations and with the interaction of additional environmental exposures. © 2016 Wiley Periodicals, Inc.

    Full Text Available Abstract Background The impact of outdoor air pollution on infant mortality has not been quantified. Methods Based on exposure-response functions from a U.S. cohort study, we assessed the attributable risk of postneonatal infant mortality in 23 U.S. metropolitan areas related to particulate matter 10 as a surrogate of total air pollution. Results The estimated proportion of all cause mortality, sudden infant death syndrome (normal birth weight infants only and respiratory disease mortality (normal birth weight attributable to PM10 above a chosen reference value of 12.0 μg/m3 PM10 was 6% (95% confidence interval 3–11%, 16% (95% confidence interval 9–23% and 24% (95% confidence interval 7–44%, respectively. The expected number of infant deaths per year in the selected areas was 106 (95% confidence interval 53–185, 79 (95% confidence interval 46–111 and 15 (95% confidence interval 5–27, respectively. Approximately 75% of cases were from areas where the current levels are at or below the new U.S. PM2.5 standard of 15 μg/m3 (equivalent to 25 μg/m3 PM10. In a country where infant mortality rates and air pollution levels are relatively low, ambient air pollution as measured by particulate matter contributes to a substantial fraction of infant death, especially for those due to sudden infant death syndrome and respiratory disease. Even if all counties would comply to the new PM2.5 standard, the majority of the estimated burden would remain. Conclusion Given the inherent limitations of risk assessments, further studies are needed to support and quantify the relationship between infant mortality and air pollution.

    The WHO (2001) recommends exclusive breast-feeding and delaying the introduction of solid foods to an infant\\'s diet until 6 months postpartum. However, in many countries, this recommendation is followed by few mothers, and earlier weaning onto solids is a commonly reported global practice. Therefore, this prospective, observational study aimed to assess compliance with the WHO recommendation and examine weaning practices, including the timing of weaning of infants, and to investigate the factors that predict weaning at ≤ 12 weeks. From an initial sample of 539 pregnant women recruited from the Coombe Women and Infants University Hospital, Dublin, 401 eligible mothers were followed up at 6 weeks and 6 months postpartum. Quantitative data were obtained on mothers\\' weaning practices using semi-structured questionnaires and a short dietary history of the infant\\'s usual diet at 6 months. Only one mother (0.2%) complied with the WHO recommendation to exclusively breastfeed up to 6 months. Ninety-one (22.6%) infants were prematurely weaned onto solids at ≤ 12 weeks with predictive factors after adjustment, including mothers\\' antenatal reporting that infants should be weaned onto solids at ≤ 12 weeks, formula feeding at 12 weeks and mothers\\' reporting of the maternal grandmother as the principal source of advice on infant feeding. Mothers who weaned their infants at ≤ 12 weeks were more likely to engage in other sub-optimal weaning practices, including the addition of non-recommended condiments to their infants\\' foods. Provision of professional advice and exploring antenatal maternal misperceptions are potential areas for targeted interventions to improve compliance with the recommended weaning practices.

    Full Text Available The objective of the article is to analyse and present the classification of risks actual to derivative securities. The analysis is based on classical and modern literature findings and analysis of newest statistical data. The analysis led to the conclusion, that the main risks typical for derivatives contracts and their traders are market risk, liquidity risk, credit and counterparty risk, legal risk and transactions risk. Pricing risk and systemic risk is also quite important. The analysis showed that market risk is the most important kind of risk that in many situations influences the level of remaining risks.

    Urinary tract infection (UTI) is the most frequent severe bacterial infection in infants. Up to 31% of infants with UTI have bacteremia. We retrospectively identified all infants aged 0-2 months who were managed in our hospital with UTI during a 1-year period. Those with bacteremia were compared with those without bacteremia, according to the following variables: ethnicity, age, gender, white blood cell and polymorphonuclear counts, C-reactive protein, urinalysis and blood creatinine values as related to age-appropriate norms, imaging and outcome. We identified 81 infants with 82 episodes of UTI. Most occurred in males (72.8%) and 35 (42.7%) were in infants of non-Jewish origin. In 14/81 (17.3%) of episodes, Escherichia coli was cultured from blood. In multivariate analysis, increased blood creatinine levels (P = 0.004) and non-Jewish origin (P = 0.006) were associated with bacteremia. Time to defervescence was significantly longer in bacteremic versus nonbacteremic children (P = 0.018). Duration of hospitalization was longer in bacteremic infants-10 (7-17) days in bacteremic versus 7 (1-14) days in nonbacteremic children (P < 0.001). In infants aged 0-2 months with UTI, increased blood creatinine value at admission was associated with bacteremia. This value provides an additional clue on admission, independent of personal judgment, to help identify infants at higher risk for bacteremia, prolonged hospitalization and possible complications.

    The relationship between various risk factors and lung cancer was evaluated in a case-control study. One hundred and forty-one cancer patients newly cytologically or pathologically diagnosed from May 1990 to July 1991 at Tri-Service General Hospital (TSGH) were recruited as cases. Two control groups were also studied: 282 hospital controls two-to-one matched with cases on sex, age, hospital of admission and insurance status were selected from the TSGH Ophthalmologic Department, and 282 neighborhood controls two-to-one matched on sex, age, and residence were randomly selected from eligible neighbors. A comparison of interview data between cases and hospital controls based on multiple conditional logistic regression revealed that cigarette smoking, keeping doves as pet, occupational exposure to cotton dust and working as a cook were risk factors for lung cancer. An inverse association between incense burning and lung cancer was noted. The comparison between cases and neighborhood controls showed lung cancer was significantly associated with cigarette smoking, keeping doves, prior chronic bronchitis, occupational exposure to cotton dust, asbestos and radiation, low frequency of burning incense, and low intake of vitamin A derived from vegetables and fruits. There was no association between lung cancer and working as a cook when cases were compared with neighborhood controls.

    Full Text Available OBJECTIVE: The aim of this study was to determine the prevalence and risk factors of posttransplant erythrocytosis (PTE. MATERIAL and METHODS: The study included 96 patients who received a renal allograft between 2005-2009 years. PTE was defined as an elevated hematocrit level greater than 51% after renal transplantation in patients receiving an allograft. RESULTS: Of the 96 adult kidney recipients, 15 (15,6% developed PTE. The mean time from transplantation to diagnosis was 7,3 ± 2,8 months ( range, 4,5-13 months . Mean serum creatinine was 1,12 ±0,3 mg/dl (0,8-1,99 mg/dl at the diagnosis of PTE. PTE was more frequent in male patients (p<0.05 and the patients with a long duration on dialysis prior to transplantation (p<0.05. There was no significant difference in patient age, donor source, donor age and immunosuppressive therapy on comparing the PTE group and non PTE groups. None of the patients with erythrocytosis experienced thromboembolic events during follow-up. CONCLUSION: PTE developed in the first year after transplantation. Male gender and a long duration on dialysis prior to transplantation are risk factors of PTE.

    2016-08-01

    Full Text Available Perinatal period may pose a great challenge for the clinical management and treatment of psychiatric disorders in women. In fact, several mental illnesses can arise during pregnancy and/or following childbirth. Suicide and infanticide have been considered relatively rare events during the perinatal period. However, in some mental disorders (i.e. postpartum depression, bipolar disorder, postpartum psychosis, etc. have been reported a higher risk of suicidal ideation, suicide attempt or suicide. Therefore, a complete screening of mothers’ mental health should also take into account thoughts of suicide and thoughts about harming infants as well. Clinicians should carefully monitor and early identify related clinical manifestations, potential risk factors and alarm symptoms related to suicide. The present paper aims at providing a focused review about epidemiological data, risk and protective factors and an overview about the main clinical correlates associated with the suicidal behaviour during the pregnancy and postpartum period.

    The aim of this study was to determine the incidence of neonatal deafness and how effective screening could be in a cohort of infants under the national health service in Mestre Venice. The criteria used in the screening of a population at risk were those established by the JCIH (1990). All the children born between September 1992 and August 1995 (4408 infants) were examined in an attempt to identify risk factors. The children presenting one or more risk factors and those admitted to neonatal intensive care for any reason were submitted to ABR testing. The results were considered negative if the wave V was perceived at an intensity 21 trisomia while it proved impossible to determine the cause of deafness in the remaining two. As indicated in other studies, application of a risk register makes it possible to identify congenital deafness in 50-60% of the cases. For this reason the authors consider mass screening through the use of oto-acoustic emissions to be quite useful.

  18. Association of surfactant protein A polymorphisms with otitis media in infants at risk for asthma

    2006-08-01

    Full Text Available Abstract Background Otitis media is one of the most common infections of early childhood. Surfactant protein A functions as part of the innate immune response, which plays an important role in preventing infections early in life. This prospective study utilized a candidate gene approach to evaluate the association between polymorphisms in loci encoding SP-A and risk of otitis media during the first year of life among a cohort of infants at risk for developing asthma. Methods Between September 1996 and December 1998, women were invited to participate if they had at least one other child with physician-diagnosed asthma. Each mother was given a standardized questionnaire within 4 months of her infant's birth. Infant respiratory symptoms were collected during quarterly telephone interviews at 6, 9 and 12 months of age. Genotyping was done on 355 infants for whom whole blood and complete otitis media data were available. Results Polymorphisms at codons 19, 62, and 133 in SP-A1, and 223 in SP-A2 were associated with race/ethnicity. In logistic regression models incorporating estimates of uncertainty in haplotype assignment, the 6A4/1A5haplotype was protective for otitis media among white infants in our study population (OR 0.23; 95% CI 0.07,0.73. Conclusion These results indicate that polymorphisms within SP-A loci may be associated with otitis media in white infants. Larger confirmatory studies in all ethnic groups are warranted.

  19. Maternal and infant factors associated with reasons for introducing solid foods.

    Brown, Amy; Rowan, Hannah

    2016-07-01

    The current UK Department of Health advice is to introduce solid foods to infants at around 6 months of age, when the infant is showing signs of developmental readiness for solid foods. However, many mothers introduce solid foods before this time, and for a wide variety of reasons, some of which may not promote healthy outcomes. The aim of the current study was to examine infant and maternal characteristics associated with different reasons for introducing solid foods. Seven hundred fifty-six mothers with an infant aged 6-12 months old completed a questionnaire describing their main reason for introducing solid foods alongside demographic questions, infant weight, gender, breast/formula feeding and timing of introduction to solid foods. The majority of mothers introduced solid foods for reasons explicitly stated in the Department of Health advice as not signs of readiness for solid foods. These reasons centred on perceived infant lack of sleep, hunger or unsettled behaviour. Maternal age, education and parity, infant weight and gender and breast/formula feeding choices were all associated with reasons for introduction. A particular association was found between breastfeeding and perceiving the infant to be hungrier or needing more than milk could offer. Male infants were perceived as hungry and needing more energy than female infants. Notably, signs of readiness may be misinterpreted with some stating this reason for infants weaned prior to 16 weeks. The findings are important for those working to support and educate new parents with the introduction of solid foods in understanding the factors that might influence them.

    1988-09-01

    To evaluate recent immunization against diphtheria, tetanus, and pertussis (DTP) as a possible risk factor for sudden infant death syndrome (SIDS), we studied the rates of SIDS after the administration of DTP vaccine in a cohort of 129,834 children who were born in four urban Tennessee counties during the period from 1974 through 1984. All the children received at least one DTP immunization in the first year of life at county health-department clinics or from Medicaid providers. Computerized immunization records from these sources were linked with Tennessee birth and death certificates to establish the cohort, ascertain the timing of immunization, and identify cases of SIDS. These children represented 42 percent of the births in the four counties. Among these children, 204 deaths occurred at the ages of 29 to 365 days; 109 deaths were classified as due to SIDS. We estimated the risk of SIDS according to the length of time, up to 30 days, since DTP immunization and compared it with the risk 31 days or more after immunization to calculate the relative risk. With control for age, the relative risk from 0 to 3 days after DTP immunization was 0.18 (95 percent confidence interval, 0.04 to 0.8); from 4 to 7 days, 0.17 (95 percent confidence interval, 0.04 to 0.7); from 8 to 14 days, 0.75 (95 percent confidence interval, 0.4 to 1.5); and from 15 to 30 days, 1.0 (95 percent confidence interval, 0.6 to 1.6). A multivariate analysis in which we controlled for age, sex, race, year, birth weight, and Medicaid enrollment, produced similar results. We conclude that in this large population of children there was no increase in the risk of SIDS after immunization with the DTP vaccine.

  2. Transient Hypothyroidism in Premature Infants After Short-term Topical Iodine Exposure: An Avoidable Risk?

    Jordan E. Pinsker

    2013-04-01

    Full Text Available Studies in preterm infants have shown that prolonged treatment with topical iodine (multiple doses, often over multiple days can transiently suppress thyroid function. However, it is uncertain if topical iodine exposure for very short periods of time can cause significant changes in thyroid function. We report two cases of transient hypothyroidism in preterm infants after short-term exposure to topical iodine during surgical preparation, and review their clinical and laboratory findings before and after iodine exposure. We conclude that premature infants are at risk of developing transient hypothyroidism in response to a single, short-term exposure to topical iodine, even in iodine-sufficient geographical areas. We advise monitoring of thyroid function in these infants after iodine exposure, as treatment with levothyroxine may be needed for a limited duration to prevent the sequelae of untreated hypothyroidism. Consideration of using alternative cleansing agents is also advised.

    The marked increase in infants born with microcephaly in Brazil after a 2015 outbreak of Zika virus (Zika virus) disease suggests an association between maternal Zika virus infection and congenital microcephaly. To project the timing of delivery of infants born to mothers infected during early pregnancy in 1 city in Bahia State, Brazil, we incorporated data on reported Zika virus disease cases and microcephaly cases into a graphical schematic of weekly birth cohorts. We projected that these births would occur through February 2016. Applying similar projections to a hypothetical location at which Zika virus transmission started in November, we projected that full-term infants at risk for Zika virus infection would be born during April-September 2016. We also developed a modifiable spreadsheet tool that public health officials and researchers can use for their countries to plan for deliveries of infants to women who were infected with Zika virus during different pregnancy trimesters.

    A prominent theoretical view is that the brain is inherently predictive [1, 2] and that prediction helps drive the engine of development [3, 4]. Although infants exhibit neural signatures of top-down sensory prediction [5, 6], in order to establish that prediction supports development, it must be established that deficits in early prediction abilities alter trajectories. We investigated prediction in infants born prematurely, a leading cause of neuro-cognitive impairment worldwide [7]. Prematurity, independent of medical complications, leads to developmental disturbances [8-12] and a broad range of developmental delays [13-17]. Is an alteration in early prediction abilities the common cause? Using functional near-infrared spectroscopy (fNIRS), we measured top-down sensory prediction in preterm infants (born identification of infants at risk and could guide early intervention regimens.

    Full Text Available Teenage pregnancy is a worldwide medical and social issue, associated with many physical, psychological and social consequences and can result in birth, miscarriage or abortion. Aim: The aim of the present study is to find those risk factors that contribute to teenage pregnancy. Results: In U.S.A., according to data from Unicef, the birth rate among teenagers touches the 52.1% and it is four times higher, than the corresponding rate recorded in the countries of Western Europe. The United Kingdom has the highest rate of teenage pregnancy in Europe and in contrast to the decline in the rate of teenage pregnancy, recorded in the remaining countries of Western Europe, this figure has remained relatively stable, especially in adolescents aged 16 years and below. In Greece, according to National Statistics Office, in 2007, we had 3.129 births by teenagers under 18, with 75 births by teenagers under 15. The main factors contributing to the incidence of teenage pregnancy are socioeconomic factors, the family, the education and the sexual behavior of teenagers. Conclusions.It is necessary the state, through the health services and the education programs, to provide modern sex education in schools, as well as programs of prevention and health education in primary health care. The cooperation of these authorities is essential, to better address the extent and consequences of teenage pregnancy.

    Full Text Available Introduction: Although the quality of parent-child relationships is known to be associated with the offspring's mental health, little is known about the prevalence of problematic relationships in this scenario. This cross-sectional study aims to investigate the prevalence and risk factors of different types of early parent-infant relationships in a Brazilian population group. Methods: During 1 year, all families (n = 230 from an urban community of Porto Alegre, southern Brazil, with 4-month-old infants born in public hospitals were identified, and 148 were fully investigated by two family therapists. This study describes data on the 116 infants with two-parent families. Demographic, obstetric, and relational variables were collected through questionnaires and scales (Parent-Infant Relationship Global Assessment Scale, Global Assessment of Relational Functioning, and Self-Report Questionnaire. Prevalence ratios were calculated, and Poisson regression with robust variance was performed to adjust for covariates. Results: Almost 10% of mothers and 12% of fathers showed at least a significantly perturbed relationship with their 4-month-old infants. Inadequate mother-infant bonding coincided with evidence of paternal mental disorder, poor maternal social network, and discontinuation of breastfeeding at 4 months. A problematic father-infant relationship was associated with a dysfunctional couple relationship and with low infant birth weight. Conclusions: There is a high prevalence of early parent-child relationship problems, suggesting a need for health system interventions. Parent-infant relational problems are prevalent very early in life and more associated with other relational problems than with socioeconomic burden.Introdução: Embora seja consenso que a qualidade das relações pais-filho influencie a saúde mental da prole, pouco se sabe sobre a prevalência de relações problemáticas nessa esfera.

    2017-02-03

    Stroke is a heterogeneous syndrome, and determining risk factors and treatment depends on the specific pathogenesis of stroke. Risk factors for stroke can be categorized as modifiable and nonmodifiable. Age, sex, and race/ethnicity are nonmodifiable risk factors for both ischemic and hemorrhagic stroke, while hypertension, smoking, diet, and physical inactivity are among some of the more commonly reported modifiable risk factors. More recently described risk factors and triggers of stroke include inflammatory disorders, infection, pollution, and cardiac atrial disorders independent of atrial fibrillation. Single-gene disorders may cause rare, hereditary disorders for which stroke is a primary manifestation. Recent research also suggests that common and rare genetic polymorphisms can influence risk of more common causes of stroke, due to both other risk factors and specific stroke mechanisms, such as atrial fibrillation. Genetic factors, particularly those with environmental interactions, may be more modifiable than previously recognized. Stroke prevention has generally focused on modifiable risk factors. Lifestyle and behavioral modification, such as dietary changes or smoking cessation, not only reduces stroke risk, but also reduces the risk of other cardiovascular diseases. Other prevention strategies include identifying and treating medical conditions, such as hypertension and diabetes, that increase stroke risk. Recent research into risk factors and genetics of stroke has not only identified those at risk for stroke but also identified ways to target at-risk populations for stroke prevention. © 2017 American Heart Association, Inc.

  9. Arousal responses in babies at risk of sudden infant death syndrome at different postnatal ages.

    LENUS (Irish Health Repository)

    Dunne, K P

    1992-03-01

    Hypercarbic and hypoxic arousal responses during sleep were measured in healthy term infants, infants where a previous sibling died from sudden infant death syndrome (SIDS) and infants suffering a clearly defined apparent life threatening event (ALTE) requiring vigorous or mouth to mouth resuscitation. Groups of infants were tested at approximately one, six and 13 weeks postnatally. Arousal was defined as gross body movement with eyes opening and moving or crying. Hypercarbic arousal was by step increases in F1 Co2 until arousal occurred or until endtidal (PETCO2) reached 8.7 KpA (65 mm Hg) Hypoxic arousal was by step decreases in FIO2 until arousal occurred or until an FIO2 of 0.15 had been maintained for 20 minutes. There was no difference in hypercaribic arousal threshold with age in any group. Hypercarbic arousal threshold was significantly higher in siblings (mean 53.4, 53.6, 54.7 mmHg. [7.12, 7.14, 7.29 KPA] at 0, 6, 13 postnatal weeks) compared to controls (mean 50.9, 52.3, 53.0mm Hg. [6.78, 6.97, 7.29 KPS respectively). ALTE infants differed only at 12 weeks having a significantly lower threshold (51.0mmHg. [6.80 KPA] V 53.0mm Hg. (7.06 KPA]) compared to controls. There was no difference in hypoxic arousal response with age in any group. An arousal response to hypoxia occurred in only 22% of ALTE infants and 40% of siblings compared to 67% of normal infants. Deficient sleep arousal, especially to hypoxia, is common in infants and especially those considered at increased risk from SIDS. This deficiency is present in the first postnatal week and did not vary overy the first three months of postnatal life.

    Background and Aim Many preterm infants are not capable of exclusive breastfeeding from birth. To guide mothers in breastfeeding, it is important to know when preterm infants can initiate breastfeeding and progress. The aim was to analyse postmenstrual age (PMA) at breastfeeding milestones in different preterm gestational age (GA) groups, to describe rates of breastfeeding duration at pre-defined times, as well as analyse factors associated with PMA at the establishment of exclusive breastfeeding. Methods The study was part of a prospective survey of a national Danish cohort of preterm infants based on questionnaires and structured telephone interviews, including 1,221 mothers and their 1,488 preterm infants with GA of 24–36 weeks. Results Of the preterm infants, 99% initiated breastfeeding and 68% were discharged exclusively breastfed. Breastfeeding milestones were generally reached at different PMAs for different GA groups, but preterm infants were able to initiate breastfeeding at early times, with some delay in infants less than GA 32 weeks. Very preterm infants had lowest mean PMA (35.5 weeks) at first complete breastfeed, and moderate preterm infants had lowest mean PMA at the establishment of exclusive breastfeeding (36.4 weeks). Admitting mothers to the NICU together with the infant and minimising the use of a pacifier during breastfeeding transition were associated with 1.6 (95% CI 0.4–2.8) and 1.2 days (95% CI 0.1–2.3) earlier establishment of exclusive breastfeeding respectively. Infants that were small for gestational age were associated with 5.6 days (95% CI 4.1–7.0) later establishment of exclusive breastfeeding. Conclusion Breastfeeding competence is not developed at a fixed PMA, but is influenced by multiple factors in infants, mothers and clinical practice. Admitting mothers together with their infants to the NICU and minimising the use of pacifiers may contribute to earlier establishment of exclusive breastfeeding. PMID:25251690

    .OBJECTIVE: To determine the incidence of bronchopulmonary dysplasia, its risk factors and resource utilization in a large South American population of very low birth weight infants. METHODS: Data were prospectively collected from infants weighing 500 to 1,500 g born at 16 NEOCOSUR Network centers from 10/2000 through 12/2003. Multivariate relative risk and 95% confidence intervals were estimated by Poisson regression with robust error variance to find factors that affected the risk of bronchopulmonary dysplasia. RESULTS: 1,825 very low birth weight infant survivors were analyzed. Mean birth weight and gestational age were 1085+279 g and 29+3 weeks respectively. Bronchopulmonary dysplasia incidence averaged 24.4% and survival without bronchopulmonary dysplasia augmented with increasing gestational age. Higher birth weight and gestational age and a female gender all decreased the risk for bronchopulmonary dysplasia. Factors that independently increased that risk were surfactant requirement, mechanical ventilation, air leak, patent ductus arteriosus, late onset sepsis and necrotizing enterocolitis. Bronchopulmonary dysplasia infants had more days of hospitalization (91±27 vs. 51±19, on mechanical ventilation (19±20 vs. 4±7 and oxygen therapy (72±30 vs. 8±14 in comparison with non BPD infants. CONCLUSIONS: Bronchopulmonary dysplasia incidence was 24.4% in a large South American population and is related to greater resource utilization. Risk factors for bronchopulmonary dysplasia in this study were: surfactant requirement, mechanical ventilation, air leak, patent ductus arteriosus, late onset sepsis and necrotizing enterocolitis. These studies may provide information useful to the design of effective preventive perinatal strategies.

    Schizophrenia (SZ) is a complex and strongly heritable mental disorder, which is also associated with developmental-environmental triggers. As opposed to most diagnosable diseases (yet similar to other mental disorders), SZ diagnosis is commonly based on psychiatric evaluations. Recently, large-scale genetic and epigenetic approaches have been applied to SZ research with the goal of potentially improving diagnosis. Increased computational analyses and applied statistical algorithms may shed some light on the complex genetic and epigenetic pathways contributing to SZ pathogenesis. This review discusses the latest advances in molecular risk factors and diagnostics for SZ. Approaches such as these may lead to a more accurate definition of SZ and assist in creating extended and reliable clinical diagnoses with the potential for personalized treatment.

    Full Text Available Objective: Retinopathy of prematurity (ROP is a disease of the eye caused by disorganized growth of retinal blood vessels resulting in scarring and retinal detachment. All preterm babies are at high risk for ROP, and very low birth weight is an additional risk factor. An increased incidence of ROP is expected in Iran because of improved survival of low birth weight and premature babies, and it is obvious that pediatricians and ophthalmologists are concerned about prevention and timely treatment of ROP in these children. To asses the real situation of ROP in our NICU we studied its prevalence and risk factors. Methods: This was a retrospective analysis of premature infants with birth weight of ≤1500 grams or gestational age of ≤32 weeks, admitted April 1, 2005 to March 28, 2006, to the Neonatal Intensive Care Unit of Qaem Hospital, Mashhad, Iran. The collected data of 47 cases in this cross-sectional study are analyzed by SPSS (Mann_Whitney, t-Student. Findings: Forty five infants were included in the study. Out of these, 4 (8.5% developed ROP (inclusive all stages. Our analysis revealed that low gestational age, sepsis and respiratory distress syndrome were independent predictors for the development of ROP. Conclusion:The frequency of ROP in our hospital was lower than the range reported in developed countries, and our risk factors were a little different.

  18. Formula and scale for body surface area estimation in high-risk infants.

    Advances in medical technology and the health sciences have lead to a rapid increase in the prevalence and morbidity of high-risk infants with chronic or permanent sequels such as the birth of early preterm infants. A suitable formula is therefore needed for body surface area (BSA) estimation for high-risk infants to more accurately devise therapeutic regimes in clinical practice. A cohort study involving 5014 high-risk infants was conducted to develop a suitable formula for estimating BSA using four of the existing formulas in the literature. BSA of high-risk infants was calculated using the four BSA equations (Boyd-BSA, Dubois-BSA, Meban-BSA, Mosteller-BSA), from which a new calculation, Mean-BSA, was arithmetically derived as a reference BSA measure. Multiple-regression was performed using nonlinear least squares curve fitting corresponding to the trend line and the new equation, Neo-BSA, developed using Excel and SPSS 17.0. The Neo-BSA equation was constructed as follows: Neo-BSA = 5.520 x W(0.5526) x L(0.300). With the assumption of the least square root relation between weight and length, a BSA scale using only weight was fabricated specifically for clinical applications where weight is more available in high-risk infant populations than is length. The validity of Neo-BSA was evaluated against Meban-BSA, the best of the four equations for high-risk infants, as there is a similarity of subjects in the two studies. The other formulas revealed substantial variances in BSA compared to Neo-BSA. This study developed a new surface area equation, Neo-BSA, as the most suitable formula for BSA measurement of high-risk infants in modern-day societies, where an emerging population of newborns with shorten gestational ages are becoming more prevalent as a result of new advances in the health sciences and new development of reproductive technologies. In particular, a scale for 400-7000 g body weight babies derived from the Neo-BSA equation has the clinical advantage of

    Full Text Available Abstract Background Increased survival of extremely low birth infants due to advances in antenatal and neonatal care has resulted in a population of infants at high risk of developing retinopathy of prematurity (ROP. Therapeutic interventions include the use of antenatal and postnatal steroids however, their effects on the severity of ROP is in dispute. In addition, it has not been investigated whether severe ROP is due to therapeutic interventions or due to the severity of illness. The aim of the present study was to assess the association between the incidence of severe retinopathy of prematurity (greater than stage 2 – International classification of ROP and mechanical ventilation, oxygen therapy, gestational age, antenatal and postnatal steroids in extremely low birth weight infants. Methods Neonates admitted to the neonatal intensive care unit in Lansing, Michigan, during 1993–2000 were followed to determine factors influencing the development of severe retinopathy of prematurity. Ophthalmologic examinations were started at 6 weeks and followed until resolution. We used logistic regression to estimate the relative risk (odds ratio associated with risk factors of ROP. Results Of the neonates with ≤ 1500 g birth weight, admitted to the neonatal intensive care unit, 85% (616/725 survived. Severe retinopathy of prematurity was detected in 7.8% of 576 neonates who had eye examinations. Neonates of lower gestational age (≤ 25 weeks and 26–28 weeks had an increased odds ratio of 8.49 and 3.19 for the development of severe retinopathy of prematurity, respectively, compared to those 29 weeks and older. Late postnatal steroid treatment starting after 3 weeks of life showed 2.9-fold increased odds ratio, in particular administration for two weeks and more (OR: 4.09, 95% CI: 1.52–11.03. With increasing antenatal steroids courses the risk of severe retinopathy of prematurity decreased, however, it was not significant. Lower gestational age

    Colorectal carcinoma constitutes the second, as for the rate, death cause due to a malignant disease both in the western countries and in Poland. Despite deep knowledge concerning morphogenesis and spread of colorectal carcinoma as well as vast achievements in surgery, chemo- and radiotherapy, the percentage of 5-year-survivals still reaches 40%. According to most authors there are 4 risk factor categories: epidemiological, intestinal, dietetic, and mixed. It is well-known that colorectal carcinoma, like neoplasms localized in other organs and systems, is a disease, in which genetic mutations of somatic cells are the molecular base/source of the disease. The inner innervation of the colon seems to play an important role in carcinoma pathogenesis and spread. At present, 80% of colorectal carcinomas are diagnosed in the advanced stage, with infiltration exceeding the intestinal wall or spreading to neighboring organs, which gives full clinical symptoms. The prognosis as to survival and disease progression is usually poor. Therefore, the ways of early diagnosis, monitoring, and the knowledge of etiological factors are so important in medical practice.

    OBJECTIVE Congenital hydrocephalus (CH) is one of the most frequent CNS congenital malformations, representing an entity with serious pathological consequences. Although several studies have previously assessed child-related risk factors associated with CH development, there is a gap of knowledge on maternal environmental risk factors related to CH. The authors have systematically assessed extrinsic factors in the maternal environment that potentially confer an increased risk of CH development. METHODS The Cochrane Library, MEDLINE, and EMBASE were systematically searched for works published between 1966 and December 2015 to identify all relevant articles published in English. Only studies that investigated environmental risk factors concerning the mother-either during gestation or pregestationally-were included. RESULTS In total, 13 studies (5 cohorts, 3 case series, 3 case-control studies, 1 meta-analysis, and 1 case report) meeting the inclusion criteria were identified. Maternal medication or alcohol use during gestation; lifestyle modifiable maternal pathologies such as obesity, diabetes, or hypertension; lack of prenatal care; and a low socioeconomic status were identified as significant maternal environmental risk factors for CH development. Maternal infections and trauma to the mother during pregnancy have also been highlighted as potential mother-related risk factors for CH. CONCLUSIONS Congenital hydrocephalus is an important cause of serious infant health disability that can lead to health inequalities among adults. The present study identified several maternal environmental risk factors for CH, thus yielding important scientific information relevant to prevention of some CH cases. However, further research is warranted to confirm the impact of the identified factors and examine their underlying behavioral and/or biological basis, leading to the generation of suitable prevention strategies.

    Despite recommendations against routine imaging, chest radiography (CXR) is frequently performed on infants hospitalized for bronchiolitis. We conducted a review of 811 infants hospitalized for bronchiolitis to identify clinical factors associated with imaging findings. CXR was performed on 553 (68%) infants either on presentation or during hospitalization; 466 readings (84%) were normal or consistent with viral illness. Clinical factors significantly associated with normal/viral imaging were normal temperature (odds ratio = 1.66; 95% CI = 1.03-2.67) and normal oxygen saturation (odds ratio = 1.77; 95% CI = 1.1-2.83) on presentation. Afebrile patients with normal oxygen saturations were nearly 3 times as likely to have a normal/viral CXR as patients with both fever and hypoxia. Our findings support the limited role of radiography in the evaluation of hospitalized infants with bronchiolitis, especially patients without fever or hypoxia.

    Prenatal psychosocial exposures can significantly affect infant health and development. Infants with higher temperamental negativity are theorized to be more susceptible to environmental exposures. We evaluated the interaction of prenatal maternal exposures and infant temperamental negativity to predict infant cortisol response to mildly challenging mother-infant interaction tasks. Participants included 322 Mexican American mother-infant dyads (mother age 18-42; 82% Spanish-speaking; modal family income $10,000-$15,000). Mothers reported depressive symptoms and social support prenatally and infant temperamental negativity at 6 weeks postpartum. Salivary cortisol was collected from infants before and after mother-infant interaction tasks at 12 weeks. Higher prenatal maternal depressive symptoms and lower social support predicted higher cortisol among infants with higher temperamental negativity. Higher infant temperamental negativity predicted an increase in maternal distress and a decrease in social support from prenatal to 12 weeks postpartum. Interactive influences of maternal social-contextual factors and infant temperament may influence the development of infant neurobiological regulation and promote or strain maternal and infant adaptation over time.

    AIM: To estimate the prevalence of inherited and acquired thrombophilic risk factors in patients with abdominal venous thrombosis and to compare the risk factor profiles between Budd-Chiari syndromes (BCS) and splanchnic vein thrombosis (SVT).METHODS: In this retrospective study, 36 patients with abdominal venous thrombosis were studied.The patients were divided into Budd-Chiari group (hepatic vein, IVC thrombosis) and splanchnic venous thrombosis group (portal, splenic, superior mesenteric veins) based on the veins involved. Hereditary and acquired thrombophilic risk factors were evaluated in all patients.RESULTS: Twenty patients had SVT, 14 had BCS,and 2 had mixed venous thrombosis. Ten patients (28%) had hereditary and 10 patients (28%) acquired thrombophilic risk factors. The acquired risk factors were significantly more common in the SVT group (SVT vs BCS:45% vs 7%,x2=5.7,P=0.02) while hereditary risk factors did not show significant differences between the two groups (SVT vs BCS: 25%vs 36%, x2=0.46,P=0.7). Multiple risk factors were present in one (7%) patient with BCS and in 3 patients (15%) with SVT. No risk factors were identified in 57% of patients with BCS and in 45% of patients with SVT.CONCLUSION: Hereditary and acquired risk factors play an important role in the etiopathogenesis of abdominal venous thrombosis. Acquired risk factors are significantly more common in SVT patients while hereditary factors are similar in both groups.

    Inadequate nutrition during the first two years of life may lead to childhood morbidity and mortality, as well as inadequate brain development. Infants are at increased risk of malnutrition by six months, when breast milk alone is no longer sufficient to meet their nutritional requirements. However the factors associated with nutritional status of infants after 6 months of age have received little attention in pastoralist communities of Ethiopia. Therefore this study aimed to identify the factors associated with nutritional status of infants and young children (6-23 months) in Filtu town, Somali Region, Ethiopia. A cross-sectional community-based study was conducted. Simple random sampling was employed to select 214 infants for the study. Univariable and multivariable logistic regressions models were used in the statistical analysis. The strength of association was measured by odds ratios with 95% confidence intervals. Both the crude (COR) and adjusted odds ratios (AOR) are reported. The prevalence of wasting, stunting and underweight among infants and young children were 17.5% (95% CI: 12.91-23.22), 22.9% (95% CI: 17.6-28.9) and 19.5% (95% CI: 14.58-25.3) respectively. The multivariable logistic regression model showed that breastfeeding was independently associated with reduced odds of wasting (AOR = 0.38(95% CI: 0.14-0.99)). Diarrhea in the past 15 days (AOR = 2.13 (95% CI: 1.55-4.69)) was also associated with increased odds for wasting. The independent predictors of reduced odds for stunting were dietary diversity score ≥ 4 (AOR = 0.45(95% CI: 0.21-0.95)) and introduction of complementary feeding at 6 months (AOR = 0.25 (95% CI: 0.09-0.66)). Bottle feeding was associated with increased odds of stunting (AOR = 3.83 (95% CI: 1.69-8.67)). Breastfeeding was associated with reduced odds of underweight (AOR = 0.24 (95% CI: 0.1-0.59)), while diarrheal disease in the past 15 days was associated with increased odds of underweight (AOR = 3.54 (95% CI: 1

    The majority of mothers in Ireland provide formula milk to their infants during the initial weeks postpartum; however, data are lacking on their formula feeding practices and support needs. This prospective Dublin-based observational study, which included 450 eligible mother-term infant pairs recruited and followed up to 6 months postpartum, aimed to advance our understanding of maternal formula feeding practices, their reasons for deciding to formula feed, sources of feeding information and perceived support needs; insights into infant formula milk consumption patterns in relation to current feeding guidelines are also provided. In summary, the vast majority of infants at 6 weeks were provided with formula milk (n = 368; 81.8%). Positive maternal perceptions of formula feeding were among the most frequently reported reasons underlying mothers’ decision to formula feed (e.g. convenience, 17.3%). Potential public health concerns over the large formula milk volumes consumed by infants (mean 205ml\\/kilogram\\/day) relative to infant feeding guidelines (150ml\\/kilogram\\/day) were raised from this study. Some mothers continue to add solid foods to infant bottle feeds at 6 weeks (3.8%) and 6 months (6%), a non-recommended feeding practice posing a choking risk for infants. Crucially, this study highlights the need to provide greater support and information to mothers who decide to formula feed postpartum including practical information on sterilisation and formula reconstitution. While breastfeeding promotion and research continues to be a public health priority in Ireland, addressing the support and information needs of mothers who formula feed, an underrepresented and understudied population in the literature, also needs to be considered to ensure optimal health and safety for their infants.

    Full Text Available In the last few years, there has been considerable interest in the effects of excessive weight gain during childhood, due to the fact that the development of fat tissue in this period is a determinant of adult body composition. The objective of this study was to investigate the prevalence of infant obesity, to identify possible etiological factors, and to highlight treatments that have been used to reduce and/or prevent child obesity. Results have shown that obesity has increased more than any other nutritional problem in both developed and developing countries over the last decade. Etiological factors linked to childhood obesity were early weaning, introduction of inadequate nutrition, and physical inactivity. The treatment of childhood obesity requires a multidisciplinary team consisting of a doctor, nutritionist, psychologist, and physical educator. There are also some general recommendations to be followed: a balanced diet for adequate growth and weight control, and controlled physical exercise together with individual and family emotional support. Parental cooperation is important for the best results. Schools also have a fundamental role in teaching children positive attitudes and behavior towards physical activity and nutrition.

    To assess the performance of the Yale Observation Scale (YOS) score and unstructured clinician suspicion to identify febrile infants ≤60 days of age with and without serious bacterial infections (SBIs). We performed a planned secondary analysis of a prospective cohort of non-critically ill, febrile, full-term infants ≤60 days of age presenting to 1 of 26 participating emergency departments in the Pediatric Emergency Care Applied Research Network. We defined SBIs as urinary tract infections, bacteremia, or bacterial meningitis, with the latter 2 considered invasive bacterial infections. Emergency department clinicians applied the YOS (range: 6-30; normal score: ≤10) and estimated the risk of SBI using unstructured clinician suspicion (50%). Of the 4591 eligible infants, 444 (9.7%) had SBIs and 97 (2.1%) had invasive bacterial infections. Of the 4058 infants with YOS scores of ≤10, 388 (9.6%) had SBIs (sensitivity: 51/439 [11.6%]; 95% confidence interval [CI]: 8.8%-15.0%; negative predictive value: 3670/4058 [90.4%]; 95% CI: 89.5%-91.3%) and 72 (1.8%) had invasive bacterial infections (sensitivity 23/95 [24.2%], 95% CI: 16.0%-34.1%; negative predictive value: 3983/4055 [98.2%], 95% CI: 97.8%-98.6%). Of the infants with clinician suspicion of <1%, 106 had SBIs (6.4%) and 16 (1.0%) had invasive bacterial infections. In this large prospective cohort of febrile infants ≤60 days of age, neither the YOS score nor unstructured clinician suspicion reliably identified those with invasive bacterial infections. More accurate clinical and laboratory predictors are needed to risk stratify febrile infants. Copyright © 2017 by the American Academy of Pediatrics.

    First, to systematically review the evidence on the effect of intervention applied during the first postnatal year in infants with or at very high risk of cerebral palsy (CP) on child and family outcome. Second, to assess whether type and dosing of intervention modify the effect of intervention. Relevant literature was identified by searching the PubMed, Embase, and CINAHL databases. Selection criteria included infants younger than 12 months corrected age with or at very high risk of CP. Methodological quality including risk of bias was scrutinized. Thirteen papers met the inclusion criteria. Seven studies with moderate to high methodological quality were analysed in detail; they evaluated neurodevelopmental treatment only (n=2), multisensory stimulation (n=1), developmental stimulation (n=2), and multifaceted interventions consisting of a mix of developmental stimulation, support of parent-infant interaction, and neurodevelopmental treatment (n=2). The heterogeneity precluded conclusions. Yet, two suggestions emerged: (1) dosing may be critical for effectiveness; (2) multifaceted intervention may offer best opportunities for child and family. The literature on early intervention in very high-risk infants with sufficient methodological quality is limited, heterogeneous, and provides weak evidence on the effect. More studies are urgently needed. Suggestions for future research are provided. © 2016 Mac Keith Press.

    The need for red cell transfusions is reduced but not eliminated by recombinant human erythropoietin (rhEPO) in very low birthweight (VLBW) infants. To detect factors associated with the decision to transfuse VLBW infants during rhEPO treatment and to explain rhEPO 'non-responders', the subgroup of those 120 VLBW infants who were treated with rhEPO 750 IU/kg per week in the second European Multicentre rhEPO Trial was evaluated. Sixty (50%) infants received at least one transfusion during erythropoietin treatment. Transfusion was frequent in infants with extremely low birthweight (79% for 750-999 g), low gestational age (70% for or = 1 ml/kg per day). The prognostic variables birthweight, initial haematocrit, and gestational age were found to be most predictive for transfusion. To improve rhEPO response in VLBW infants, there is a need to minimise diagnostic blood loss, to prevent iron deficiency, and to develop rational criteria for transfusion in preterm infants.

    There is increasing evidence that risk factors for vascular disease and stroke are associated with cognitive impairment and Alzheimer's disease. This paper reviews current knowledge on the relationship between risk factors for stroke and Alzheimer's disease. The focus will be on 'classical' risk factors, including age and gender, socioeconomic status, diabetes, cholesterol, prior cardiovascular disease, atrial fibrillation, cigarette smoking and alcohol use; as well as on factors that more recently have been recognized as putative risk factors, including APOE genotype, serum homocysteine concentration, relative abnormalities in the hemostatic and thrombotic systems, and inflammation.

    The likelihood of sustaining neurological, sensory or cognitive deficits is considerably greater for very low birthweight (VLBW) infants who require intensive care in early postnatal life than those without major neonatal illness. Identifying which, if any, medical events are responsible for an adverse outcome is most difficult in the face of multiple concurrent complications. In this research, a principal components analysis was performed in order to arrive at a set of orthogonal variables which succinctly described clinical involvement in the nursery. With this procedure, a single hypothetical factor depicting neonatal status (NS) was computed. Principal component scores were then generated for NS and assigned to 252 VLBW (less than 1500 g) infants. These subjects were followed prospectively from birth to 4 years of age. Standardized measures of neurological, sensory and intellectual function were regularly administered. Neonatal status was shown to be significantly correlated with the various test results and predictive of long-term development. When subjects were divided into quartiles with respect to NS, a specific subgroup was identified as "at high risk" for poor outcome. Those subjects falling into the lower quartile incurred more neurological abnormalities persisting beyond the first year. They also suffered a higher incidence of intracranial hemorrhage and sensori-neural hearing loss. In addition, the lower 25%, as a group, scored well below all others on traditional tests of mental ability. These differences were sustained throughout infancy and early childhood and could not be attributed to a number of demographic variables including sex, gestational age, birthweight, Apgar scores or parental educational level.

    Full Text Available Autism Spectrum Disorder (ASD is a neurodevelopmental disorder usually diagnosed after the second year of life. Early signs of ASD within the first year of life are still unclear. The main purpose of the present study was to compare object exploration skills between infants at-risk for ASD and typically developing (TD infants to determine early markers for autism within the first year of life. Sixteen at-risk infants and 16 TD infants were longitudinally followed from 6 to 15 months of age during an object exploration task involving three objects with distinct size, shape, and texture, i.e., a long rattle, a rigid circular ball, and a soft circular koosh ball. All sessions were videotaped for coding of manual, oral, and visual exploration. We also obtained follow-up outcomes using various developmental questionnaires at 18 months and email follow-up on developmental delays/ASD diagnoses after the infants’ second birthdays. Our results showed object-based differences in exploration patterns that extend across both groups. We also noticed group differences for various object exploration behaviors across objects and ages. Specifically, at 6 months, at-risk infants showed less grasping of the rigid ball as well as less mouthing and greater looking at the rattle compared to TD infants. At 9 and 12 months, at-risk infants demonstrated significantly lower levels of purposeful dropping of all objects. Lastly, at 15 months, at-risk infants looked longer at the rattle and showed persistent mouthing of the rigid ball and rattle compared to TD infants. In addition, 10 out of 16 at-risk infants developed various motor, social, and language delays or ASD diagnoses at follow-up. Taken together, early context-dependent delays/abnormalities in object exploration could be markers for future developmental delays in infants at-risk for autism. Moreover, promoting early object experiences through socially embedd
