    International Nuclear Information System (INIS)

    Wiles, H.; Lacy, J.; LeBlanc, A.; Bricker, J.; Watson, E.; Stabin, M.


    Biodistribution and retention of tungsten-178 ( 178 W) were studied in adult and infant animals in order to extrapolate radiation dose estimates to human newborns and adults. Whole body retention and organ distribution of 178 W were determined at 0.5, 2, 8, 24 and 48 hours after blood-pool injection in infant and adult rats. Percent whole body retention and percent organ uptake per gram of tissue were higher in infant than adult rats at each time interval. When extrapolated to humans on the basis of percent injected activity kilogram per gram, most organs, except bone and kidney, showed higher uptake in newborns than adults. Total body radiation dose estimates for humans from 178 w based on these data were: 0.93 mGy/MBq (3.4 rad/mCi) for newborns and 0.024 mGy/MBq (0.089 rad/mCi) for adults. 13 refs.; 5 tabs

  2. Prevention of hemolytic disease of the fetus and newborn: what have we learned from animal models? (United States)

    Cruz-Leal, Yoelys; Marjoram, Danielle; Lazarus, Alan H


    This review aims to highlight recent advances in our understanding of how anti-red blood cell (RBC) antibodies prevent erythrocyte immunization with an emphasis on new murine models. New murine models with clinically relevant human erythrocyte antigens have been used to understand the alloimmunization process and its inhibition. The search to elucidate the mechanism of action of IgG-mediated inhibition of erythrocyte alloimmunization has provided new evidence in support of a potential role for epitope masking, immune deviation and/or antigen modulation in this process. In addition, recent evidence suggests that blends of monoclonal antibodies targeting nonoverlapping epitopes on the RBC surface can improve the efficacy of monoclonal antibodies approaching that of polyclonal IgG. Animal models with defined alloantigens have helped to identify important mechanistic components that lead to alloimmunization and its inhibition by IgG. A better understanding of the underlying mechanisms leading to hemolytic disease of the fetus and newborn is required to develop the most effective prevention strategies for future patients.

  4. Chronic stress in adulthood followed by intermittent stress impairs spatial memory and the survival of newborn hippocampal cells in aging animals: prevention by FGL, a peptide mimetic of neural cell adhesion molecule

    DEFF Research Database (Denmark)

    Borcel, Erika; Pérez-Alvarez, Laura; Herrero, Ana Isabel


    In this study, we examined whether chronic stress in adulthood can exert long-term effects on spatial-cognitive abilities and on the survival of newborn hippocampal cells in aging animals. Male Wistar rats were subjected to chronic unpredictable stress at midlife (12 months old) and then reexposed...... in the hippocampus. Interestingly, spatial-memory performance in the Morris water maze was positively correlated with the number of newborn cells that survived in the dentate gyrus: better spatial memory in the water maze was associated with more 5-bromo-2-deoxyuridine (BrdU)-labeled cells. Administration of FGL......, a peptide mimetic of neural cell adhesion molecule, during the 4 weeks of continuous stress not only prevented the deleterious effects of chronic stress on spatial memory, but also reduced the survival of the newly generated hippocampal cells in aging animals. FGL treatment did not, however, prevent...

    The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG)

    To study histophysiological changes in rat testis during hypogonadism development and after xenotransplantation (XT) of newborn pig testis organ culture as well as to analyze some results of XT application when treating the patients who took part in Chernobyl accident clean-up and have sexual function disturbance. During six months after the irradiation, the signs of spermatogenic epithelium destruction, reduction of spermatogenesis activity and that of Lyedig's cells accompanied by a low blood plasma testosterone level were observed. Organ culture xenotransplantation was performed 1 month after the irradiation and during the next 3 month it activated germinative and hormonal function in the rats. Statistically significant elevation of blood plasma testosterone level was observed in the men who took part in Chernobyl accident clean-up and had disturbances of copulative and germinative functions 1 and 3 months after XT. in 6 months it was considerably higher than before the treatment

    Kilduff, C. J.


    All infants have some degree of hypoxia and respiratory acidosis at birth, but these conditions are more profound in the asphyxiated newborn. The newborn infant is very susceptible to cooling and may require warming. Skin temperature should be maintained between 36-36.5°.2 Resuscitation of the asphyxiated newborn must include both ventilatory and metabolic correction. Newborn infants may have cardiorespiratory problems due to asphyxia, drugs given to the mother, intrathoracic disease, anemia, hypovolemia (due to antepartum hemorrhage), hypotension, etc. There is no substitute for oxygen which is the drug of choice in respiratory depression of the newborn. The use of stimulating drugs like Coramine, picrotoxin, alphalobectine, and Megamide has no place in the resuscitation of the asphyxiated newborn. Imagesp74-ap74-bp74-cp74-d PMID:20469196

  5. Newborn ankyloglossia and breastfeeding

    Directory of Open Access Journals (Sweden)

    Zlata Felc


    Full Text Available Background: Tongue-tie (ankyloglossia is a relatively common finding in the newborn population and represents a significant proportion of breastfeeding problems. Ankyloglossia may result in difficulty with suckling and can lead to poor weight gain, sore nipples, low milk supply, maternal fatigue and frustration.Conclusions: By recognizing ankyloglossia early, the health care team is able to treat breastfeeding problems promptly and proactively. The pediatrician, oral-maxillofacial surgeon, and parents should work together as a team from the time of birth to determine a coordinated plan of treatment. Careful assessment of lingual function is important in selecting the correct treatment. Frenulotomy is indicated in newborns with a short and/or thick frenulum and limited lingual mobility. In newborn infants with ankyloglossia this minimal surgical procedure is an effective therapy for breastfeeding difficulties.

    Full Text Available Galactosemia is a hereditary disease, the pathogenetic treatment of which is based on dietotherapy. Early diagnosing and the adequate choice of the diet improve the development forecasts for the ill child. The article describes a classical galactosemia case in a newborn. It is shown that despite diagnosing the disease on the second month of life, the adequate selection of etiopathogenetic dietotherapy and etiotropic therapy of the concurrent diseases helped compensate the inborn galactose metabolism defect and optimize the long-term forecast for the child.Key words: inborn metabolism dysfunctions, alactosemia, dietotherapy, newborn children.

    Gingival cyst of newborn is an oral mucosal lesion of transient nature. Although it is very common lesion within 3 to 6 weeks of birth, it is very rare to visualize the lesion thereafter. Presented here is a case report of gingival cyst, which was visible just after 15 days of birth. Clinical diagnoses of these conditions are important in order to avoid unnecessary therapeutic procedure and provide suitable information to parents about the nature of the lesion.

  11. Newborn screening for galactosaemia. (United States)

    Lak, Rohollah; Yazdizadeh, Bahareh; Davari, Majid; Nouhi, Mojtaba; Kelishadi, Roya


    Classical galactosaemia is an autosomal recessive inborn error of metabolism caused by a deficiency of the enzyme galactose-1-phosphate uridyltransferase. This is a rare and potentially lethal condition that classically presents in the first week of life once milk feeds have commenced. Affected babies may present with any or all of the following: cataracts; fulminant liver failure; prolonged jaundice; or Escherichia coli sepsis. Once the diagnosis is suspected, feeds containing galactose must be stopped immediately and replaced with a soya-based formula. The majority of babies will recover, however a number will not survive. There are long-term complications of galactosaemia, despite treatment, including learning disabilities and female infertility. It has been postulated that galactosaemia could be detected on newborn screening and this would prevent the immediate severe liver dysfunction and sepsis. To assess whether there is evidence that newborn screening for galactosaemia prevents or reduces mortality and morbidity and improves clinical outcomes in affected neonates and the quality of life in older children. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register comprising references identified from electronic database searches, handsearches of relevant journals and conference abstract books. We also searched online trials registries and the reference lists of relevant articles and reviews.Date of the most recent search of Cochrane Cystic Fibrosis Group's Trials Register: 18 December 2017.Date of the most recent search of additional resources: 11 October 2017. Randomised controlled studies and controlled clinical studies, published or unpublished comparing the use of any newborn screening test to diagnose infants with galactosaemia and presenting a comparison between a screened population versus a non-screened population.

  12. A newborn with multiple fractures

    International Nuclear Information System (INIS)

    Kantorova, E.; Kratky, L.; Nevsimal, I.; Marik, K.; Kozlowski, K.


    Sometimes newborns with multiple fractures are diagnosed as osteogenesis imperfecta in spite of absence of radiographic findings supporting this diagnosis. A newborn with multiple fractures was diagnosed as osteogenesis imperfecta. Analysis of the structure of the long bones, pattern of fractures and poorly developed muscles suggested the diagnosis of fetal akinesia deformation syndrome. This was confirmed by pregnancy history and clinical findings. Multiple fractures in a newborn may present with diagnostic radiographic features as in osteogenesis imperfecta, or as in lethal gracile bone dysplasias or achondrogenesis type IA. If those features are absent, other diseases should be considered. Radiographs should be compared with pregnancy history and clinical findings in the newborn. (authors)

  15. Radiation absorption of newborns at cholescintigraphy

    International Nuclear Information System (INIS)

    Hahn, K.; Lingenfelder, B.; Wolf, R.; Eissner, D.


    The cholescintigraphy with 99m Tc-IDA has become essential to diagnose the presence of biliary atresia early in its clinical course. With this wider clinical application it is essential to have data about the radiation dose of these substances. While the radiation dose of 99m Tc-IDA has been calculated for adults there are in the literature no radiation dose calculations for newborns and young children. In this work the cumulated activity of 99m Tc-diaethyl-IDA in the organs of young pigs was measured 15, 30, 45 and 60 min. and 24 hours after injection of the radiopharmaceutical. The radiation dose calculation for newborns and youngchildren was performed on these animal biokinetic data using a biological approach including the absorbed-fraction concept. The results show that the radiation dose absorbed by the gonads as well as by the critical organs (thyroid, gallbladder, liver, upper and lower large intestine) are significantlyl lower than those of the cholescintigraphy with J-131 rose bengal. Therefore 99m Tc-IDA can be safely applied to newborns and young children. (Author)

  16. Newborn hearing screening. (United States)

    Stewart, D L; Pearlman, A


    Congenital deafness is a relatively common problem with an incidence of 1/300 to 1/1000. Most states have no mass screening program for hearing loss, but the state of Kentucky compiles a High Risk Registry which is a historical survey of parents relating to risk factors for hearing loss. Unfortunately this survey can miss 50% of those who have a hearing deficit. If not detected prior to discharge, there is often a delay in diagnosis of deafness which prevents early intervention. We report 2 years' experience at Kosair Children's Hospital where 1,987 infants admitted to well baby, intermediate, or intensive care nurseries were screened using the ALGO-1 screener (Natus Medical Inc, Foster City, CA) which is a modified auditory brain stem evoked response (ABR). Our screening of this population led to an 11% incidence of referral for complete audiological evaluation. There were no significant complications. Forty-eight infants were found to have nonspecified, sensorineural, or conductive hearing loss. The positive predictive value of the test was 96%. Therefore, we feel that the use of the modified ABR in the newborn is a timely, cost efficient method of screening for hearing loss and should be used for mass screening of all newborns.

  18. Newborn Screening for Phenylketonuria

    Directory of Open Access Journals (Sweden)

    Gustavo J. C. Borrajo PhD


    Full Text Available Newborn screening (NBS for phenylketonuria in Latin America gave its first step in an organized way 3 decades ago when the first national NBS program was implemented in Cuba. From then onward, it experienced a slow but continuous growing, being currently possible to find from countries where no NBS activity is known to several countries with consolidated NBS programs. This complex scenario gave rise to a great diversity in the criteria used for sample collection, selection of analytical methods, and definition of cutoff values. Considering this context, a consensus meeting was held in order to unify such criteria, focusing the discussion in the following aspects—recommended blood specimens and sample collection time; influence of early discharge, fasting, parenteral nutrition, blood transfusions, extracorporeal life support, and antibiotics; main causes of transient hyperphenylalaninemias; required characteristics for methods used in phenylalanine measurement; and finally, criteria to define the more appropriate cutoff values.

  19. Newborn calf welfare: a review focusing on mortality rates. (United States)

    Uetake, Katsuji


    Calf mortality control is vitally important for farmers, not only to improve animal welfare, but also to increase productivity. High calf mortality rates can be related to larger numbers of calves in a herd, employee performance, severe weather, and the neonatal period covering the first 4 weeks of life. Although the basic premise of preventing newborn calf mortality is early detection and treatment of calves at risk for failure of passive transfer of immunoglobulins, calf mortality due to infectious diseases such as acute diarrhea increases in the presence of these physical and psychological stressors. This suggests that farmers should not ignore the effects of secondary environmental factors. For prevention rather than cure, the quality of the environment should be improved, which will improve not only animal welfare but also productivity. This paper presents a review of the literature on newborn calf mortality and discusses its productivity implications. © 2012 Japanese Society of Animal Science.

  5. Heart rate variability in newborns. (United States)

    Javorka, K; Lehotska, Z; Kozar, M; Uhrikova, Z; Kolarovszki, B; Javorka, M; Zibolen, M


    Heart rate (HR) and heart rate variability (HRV) in newborns is influenced by genetic determinants, gestational and postnatal age, and other variables. Premature infants have a reduced HRV. In neonatal HRV evaluated by spectral analysis, a dominant activity can be found in low frequency (LF) band (combined parasympathetic and sympathetic component). During the first postnatal days the activity in the high frequency (HF) band (parasympathetic component) rises, together with an increase in LF band and total HRV. Hypotrophy in newborn can cause less mature autonomic cardiac control with a higher contribution of sympathetic activity to HRV as demonstrated by sequence plot analysis. During quiet sleep (QS) in newborns HF oscillations increase - a phenomenon less expressed or missing in premature infants. In active sleep (AS), HRV is enhanced in contrast to reduced activity in HF band due to the rise of spectral activity in LF band. Comparison of the HR and HRV in newborns born by physiological vaginal delivery, without (VD) and with epidural anesthesia (EDA) and via sectio cesarea (SC) showed no significant differences in HR and in HRV time domain parameters. Analysis in the frequency domain revealed, that the lowest sympathetic activity in chronotropic cardiac chronotropic regulation is in the VD group. Different neonatal pathological states can be associated with a reduction of HRV and an improvement in the health conditions is followed by changes in HRV what can be use as a possible prognostic marker. Examination of heart rate variability in neonatology can provide information on the maturity of the cardiac chronotropic regulation in early postnatal life, on postnatal adaptation and in pathological conditions about the potential dysregulation of cardiac function in newborns, especially in preterm infants.

  6. Cooling for newborns with hypoxic ischaemic encephalopathy. (United States)

    Jacobs, Susan E; Berg, Marie; Hunt, Rod; Tarnow-Mordi, William O; Inder, Terrie E; Davis, Peter G


    Newborn animal studies and pilot studies in humans suggest that mild hypothermia following peripartum hypoxia-ischaemia in newborn infants may reduce neurological sequelae without adverse effects. To determine the effect of therapeutic hypothermia in encephalopathic asphyxiated newborn infants on mortality, long-term neurodevelopmental disability and clinically important side effects. We used the standard search strategy of the Cochrane Neonatal Review Group as outlined in The Cochrane Library (Issue 2, 2007). Randomised controlled trials evaluating therapeutic hypothermia in term and late preterm newborns with hypoxic ischaemic encephalopathy were identified by searching the Oxford Database of Perinatal Trials, the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, 2007, Issue 2), MEDLINE (1966 to June 2007), previous reviews including cross-references, abstracts, conferences, symposia proceedings, expert informants and journal handsearching. We updated this search in May 2012. We included randomised controlled trials comparing the use of therapeutic hypothermia with standard care in encephalopathic term or late preterm infants with evidence of peripartum asphyxia and without recognisable major congenital anomalies. The primary outcome measure was death or long-term major neurodevelopmental disability. Other outcomes included adverse effects of cooling and 'early' indicators of neurodevelopmental outcome. Four review authors independently selected, assessed the quality of and extracted data from the included studies. Study authors were contacted for further information. Meta-analyses were performed using risk ratios (RR) and risk differences (RD) for dichotomous data, and weighted mean difference for continuous data with 95% confidence intervals (CI). We included 11 randomised controlled trials in this updated review, comprising 1505 term and late preterm infants with moderate/severe encephalopathy and evidence of intrapartum asphyxia

  7. Absorption of cadmium in the newborn and juvenile guinea pig

    International Nuclear Information System (INIS)

    Sasser, L.B.; Jarboe, G.E.


    The accepted premise that absorption is enhanced in the newborn animal is based primarily on studies using the rat, which has a relatively immature gastrointestinal system at birth. This study was conducted to determine if enhanced absorption of cadmium also occurs in the guinea pig, a species that is more precocious at birth than the rat. Newborn guinea pigs were administered a single oral dose of 5 μCi of /sup 115m/Cd (0.25 mCi of /sup 115m/Cd per milligram of cadmium) between 8 and 24 hr of age and killed at intervals between 1 and 14 days after the dosing. Juvenile guinea pigs were similarly dosed with 20 μCi of /sup 115m/Cd and killed 1 to 5 days later. Guinea pigs dosed on the day of birth absorbed approximately 6% of the dose by 1 day after the dosing and nearly 25% of the dose by 11 days. This is a cumulative absorption five times that found in rats dosed at 24 hr and two times that of rats dosed at 2 hr. The residence time of cadmium in the gastrointestinal tract was longer in newborn guinea pigs than in juvenile guinea pigs but was still significantly less than that in the newborn rat. We concluded that the absorption of cadmium from the gastrointestinal tract was greater in newborn guinea pigs than in rats, even though the residence time of cadmium in the intestinal tract was less in guinea pigs than in rats and the maturity at birth of the guinea pig is greater than that of the rat. The bases of these differences were not readily apparent

  8. Market mechanisms for newborn health in Nepal. (United States)

    Lunze, Karsten; Dawkins, Rosie; Tapia, Abeezer; Anand, Sidharth; Chu, Michael; Bloom, David E


    In Nepal, hypothermia is a major risk factor for newborn survival, but the country's public health care sector has insufficient capacity to improve newborn survival given the burden imposed by distance to health facilities and cost. Low-cost technology to provide newborn thermal care in resource-limited environments exists, but lacks effective distribution channels. This study aims to develop a private sector distribution model for dedicated newborn thermal care technology to ensure equitable access to thermal protection and ultimately improve newborn health in Nepal. We conducted a document analysis of newborn health policy in Nepal and a scoping literature review of approaches to newborn hypothermia in the region, followed by qualitative interviews with key stakeholders of newborn health in Nepal. Current solutions addressing newborn hypothermia range from high-technology, high-cost incubators to low-cost behavioral interventions such as skin-to-skin care. However, none of these interventions  are currently implemented at scale. A distribution model that provides incentives for community health volunteers and existing public health services in Nepal can deliver existing low-cost infant warmers to disadvantaged mothers where and when needed. Newborn technology can serve as an adjunct to skin-to-skin care and potentially create demand for newborn care practices. Harnessing market forces could promote public health by raising awareness of newborn challenges, such as newborn hypothermia, and triggering demand for appropriate health technology and related health promotion behaviors. Market approaches to promoting public health have been somewhat neglected, especially in economically disadvantaged and vulnerable populations, and deserve greater attention in Nepal and other settings with limited public health service delivery capacity.

  9. Bone photon absorptiometry in newborn

    Mazzoni, R; Tosca, L; Bertoli, L; Ferliga, A; Pivi, M; Marini, A


    In oreder to achieve parameters to evaluate mineralization of premature infants, bone mineral content at the midshaft of the radius was measured in 173 normal newborns. Data were correlated with the following factors: gestional age, postnatal age, sex and weight at birth. In spite of the wide range of variation of individual values, there was a statistically significant correlation between gestational age, sex and BMC.

    Riboni, G.; Serantoni, S.; De Simoni, M.; Bascape', P.; Facchini, R.; Pirovano, G.


    The authors report the data relative to 1507 cases studied with clinical and US examinations, in the neonatal period, in order to exclude hip dysplasia dislocation. US examination was carried out according to Graf's technique and the newborns were classified according to US hip type, to clinical examination and to possible risk factors. The patients were included in a protocol including orthopedic and US controls. Seventeen treated infants were considered as pathologic. Ten of them had IIc or D hips ar birth; the other 7, with IIa hips at birth, presented a X-ray pathologic hip after the 4th months of life. At about one year of age all infants could normally walk, excpet for one who was being treated with herness. No statistically significant differences were observed between the number of pathologic infants in the risk group (1.7%) and that in the no-risk group (0.8%). Clinical examination of the newborn has low sensitivity in detecting pathologic hips. On the basis of their results, thw authors belive US examination of the newborn to be a valuable screening method to diagnose hip dysplasia/dislocation. Moreover, Graf's morphologic method is the best one for US screening of the hip in the neonatal period

  11. Infusing Sodium Bicarbonate Suppresses Hydrogen Peroxide Accumulation and Superoxide Dismutase Activity in Hypoxic-Reoxygenated Newborn Piglets

    Background The effectiveness of sodium bicarbonate (SB) has recently been questioned although it is often used to correct metabolic acidosis of neonates. The aim of the present study was to examine its effect on hemodynamic changes and hydrogen peroxide (H2O2) generation in the resuscitation of hypoxic newborn animals with severe acidosis. Methods Newborn piglets were block-randomized into a sham-operated control group without hypoxia (n = 6) and two hypoxia-reoxygenation groups (2 h normocap...

  12. Isolated penile torsion in newborns. (United States)

    Eroglu, Egemen; Gundogdu, Gokhan


    We reported on the incidence of isolated penile torsion among our healthy children and our approach to this anomaly. Between 2011 and 2014, newborn babies with penile torsion were classified according to the angle of torsion. Surgical correction (penile degloving and reattachment for moderate cases and dorsal dartos flap technique in case of resistance) after 6 months was advised to the babies with rotations more than 45°. Among 1000 newborn babies, 200 isolated penile torsions were found, and among these, 43 had torsions more than 45°, and 4 of these had angles greater than 90°. The mean angle of the rotations was found 30.45° (median: 20°). In total, 8 children with 60° torsions were previously circumcised. Surgery was performed on 19 patients, with a mean patient age of 12 ± 2 months. Of these 19, 13 babies were corrected with degloving and reattachment. This technique was not enough on the remaining 6 patients; therefore, derotational dorsal dartos flap was added to correct the torsion. After a mean of 15.6 ± 9.8 months, residual penile rotation, less than 15°, was found only in 2 children. The incidence of isolated penile torsion is 20% in newborns. However, rotation more than 45° angles are seen in 4.3% of male babies. Correction is not necessary in mild degrees, and penile degloving with reattachment is enough in most cases. If the initial correction is insufficient, dorsal dartos flap rotation is easy and effective. Prior circumcision neither disturbs the operative procedure nor affects the outcomes.

  13. Flooring choices for newborn ICUs. (United States)

    White, R D


    Floors are a major element of newborn intensive care unit (NICU) construction. They provide visual cues, sound control, and with certain materials, some degree of physical comfort for workers. Flooring materials may entail a significant cost for installation and upkeep and can have substantial ecological impact, both in the choice of the flooring itself, as well as the substances used to clean it. In this article the important aspects to consider for each factor are explored and recommendations are offered for appropriate choices in various NICU areas.

  14. Unusual osteopathy in a newborn

    A newborn baby presented with hyaline membrane disease, interstitial pneumonia, jaundice, hepatosplenomegaly, and unusual bone manifestations with lytic and sclerotic bone lesions and virtually absent periosteal reaction. He subsequently developed intracranial calcifications and mental retardation. The pneumonia and hepatosplenomegaly resolved. At the time of the delivery, a sibling was suffering from a severe undetermined viral infection. The clinical evolution of the disease and the radiologic findings led us to believe that this patient has a prenatal viral infection. The laboratory tests and the histologic picture of the bone biopsy supported the diagnosis.

  20. [Recent advances in newborn MRI]. (United States)

    Morel, B; Hornoy, P; Husson, B; Bloch, I; Adamsbaum, C


    The accurate morphological exploration of the brain is a major challenge in neonatology that advances in magnetic resonance imaging (MRI) can now provide. MRI is the gold standard if an hypoxic ischemic pathology is suspected in a full term neonate. In prematures, the specific role of MRI remains to be defined, secondary to US in any case. We present a state of the art of hardware and software technical developments in MRI. The increase in magnetic field strength (3 tesla) and the emergence of new MRI sequences provide access to new information. They both have positive and negative consequences on the daily clinical data acquisition use. The semiology of brain imaging in full term newborns and prematures is more extensive and complex and thereby more difficult to interpret. The segmentation of different brain structures in the newborn, even very premature, is now available. It is now possible to dissociate the cortex and basal ganglia from the cerebral white matter, to calculate the volume of anatomical structures, which improves the morphometric quantification and the understanding of the normal and abnormal brain development. MRI is a powerful tool to analyze the neonatal brain. The relevance of the diagnostic contribution requires an adaptation of the parameters of the sequences to acquire and of the image processing methods. Copyright © 2014 Elsevier Masson SAS.

  1. Traumatic brain lesions in newborns

    Directory of Open Access Journals (Sweden)

    Nícollas Nunes Rabelo

    Full Text Available ABSTRACT The neonatal period is a highly vulnerable time for an infant. The high neonatal morbidity and mortality rates attest to the fragility of life during this period. The incidence of birth trauma is 0.8%, varying from 0.2-2 per 1,000 births. The aim of this study is to describe brain traumas, and their mechanism, anatomy considerations, and physiopathology of the newborn traumatic brain injury. Methods A literature review using the PubMed data base, MEDLINE, EMBASE, Science Direct, The Cochrane Database, Google Scholar, and clinical trials. Selected papers from 1922 to 2016 were studied. We selected 109 papers, through key-words, with inclusion and exclusion criteria. Discussion This paper discusses the risk factors for birth trauma, the anatomy of the occipito-anterior and vertex presentation, and traumatic brain lesions. Conclusion Birth-related traumatic brain injury may cause serious complications in newborn infants. Its successful management includes special training, teamwork, and an individual approach.

  2. Pulmonary hypertension of the newborn. (United States)

    Stayer, Stephen A; Liu, Yang


    Pulmonary hypertension presenting in the neonatal period can be due to congenital heart malformations (most commonly associated with obstruction to pulmonary venous drainage), high output cardiac failure from large arteriovenous malformations and persistent pulmonary hypertension of the newborn (PPHN). Of these, the most common cause is PPHN. PPHN develops when pulmonary vascular resistance (PVR) remains elevated after birth, resulting in right-to-left shunting of blood through foetal circulatory pathways. The PVR may remain elevated due to pulmonary hypoplasia, like that seen with congenital diaphragmatic hernia; maldevelopment of the pulmonary arteries, seen in meconium aspiration syndrome; and maladaption of the pulmonary vascular bed as occurs with perinatal asphyxia. These newborn patients typically require mechanical ventilatory support and those with underlying lung disease may benefit from high-frequency oscillatory ventilation or extra-corporeal membrane oxygenation (ECMO). Direct pulmonary vasodilators, such as inhaled nitric oxide, have been shown to improve the outcome and reduce the need for ECMO. However, there is very limited experience with other pulmonary vasodilators. The goals for anaesthetic management are (1) to provide an adequate depth of anaesthesia to ablate the rise in PVR associated with surgical stimuli; (2) to maintain adequate ventilation and oxygenation; and (3) to be prepared to treat a pulmonary hypertensive crisis--an acute rise in PVR with associated cardiovascular collapse.

  3. Persistent pulmonary hypertension of the newborn (United States)

    Teng, Ru-Jeng; Wu, Tzong-Jin


    Persistent pulmonary hypertension of the newborn (PPHN) is a severe pulmonary disorder which occurs one in every 500 live births. About 10–50% of the victims will die of the problem and 7–20% of the survivors develop long term impairments such as hearing deficit, chronic lung disease, and intracranial bleed. Most of the adult survivors show evidence of augmented pulmonary vasoreactivity suggesting a phenotypical change. Several animal models have been used to study the pathophysiology and help to develop new therapeutic modality for PPHN. The etiology of PPHN can be classified into three groups: [A] abnormally constricted pulmonary vasculature due to parenchymal diseases; [B] hypoplastic pulmonary vasculature; [C] normal parenchyma with remodeled pulmonary vasculature. Impaired vasorelaxation of pulmonary artery and reduced blood vessel density in lungs are two characteristic findings in PPHN. Medical treatment includes sedation, oxygen, mechanical ventilation, vasorelaxants (inhaled nitric oxide, inhaled or intravenous prostacyclin, intravenous prostaglandin E1, magnesium sulfate), and inotropic agents. Phosphodiesterase inhibitor has recently been studied as another therapeutic agent for PPHN. Endothelin-1 (ET-1) inhibitor has been studied in animal and a case of premature infant with PPHN successfully treated with ET-I inhibitor has been reported in the literature. Surfactant has been reported as an adjunct treatment for PPHN as a complication of meconium aspiration syndrome. Even with the introduction of several new therapeutic modalities there has no significant change in survival rate. Extracorporeal membrane oxygenator is used when medical treatment fails and patient is considered to have a recoverable cause of PPHN. PMID:23537863

    Full Text Available The cardiovascular system in newborns with chronic hypoxia is affected in 40–70%. Aim. To investigate morphological state of aorta in the fetuses and newborns suffered from chronic intrauterine hypoxia. Methods and results. Aortic wall was investigated with modern morphological methods in 34 laboratory animals in order to identify the morphological features of the fetuses and newborns’ vessel affected by this pathogenic factor. It was established that chronic hypoxia leads to endothelial trophics deterioration, its flattening, dystrophic processes with following cells desquamation, density reduction of smooth muscle cells, thickening of the intima-media. Conclusion. It shows alterative-sclerotic changes in aorta in cases with chronic hypoxia influence.

  5. Enhanced insulin binding to blood-brain barrier in vivo and to brain microvessels in vitro in newborn rabbits

    International Nuclear Information System (INIS)

    Frank, H.J.; Jankovic-Vokes, T.; Pardridge, W.M.; Morris, W.L.


    Insulin is a known growth factor in nonneural tissue, and recent studies have shown that there are insulin receptors throughout the adult and fetal central nervous system. Since insulin has only limited access to the adult brain, this study was undertaken to determine if insulin has increased availability to the newborn brain where it may act as a neonatal brain growth promoter. In vivo brain uptake of 125 I-insulin after a single-pass carotid injection was measured in newborn, 3-wk-old and 11-wk-old (adult) rabbits. The brain uptake index (BUI) relative to a 3 HOH reference was 22.0 +/- 1.1% (mean +/- SEM) for newborn, 12.8 +/- 0.6% for 3-wk-old, and 6.5 +/- 0.1% for adults. Specific 125 I-insulin binding to isolated cerebral microvessels was similarly increased in the newborn compared with the 3-wk-old and adult animals. Scatchard analysis revealed that the difference was due to an increase in receptor number with only minimal changes in the affinity. The increased availability of circulating insulin to the newborn brain was further corroborated by elevated CSF/serum and brain/serum insulin ratios in the newborn versus adult. These results suggest that insulin has increased access to the newborn brain where it may function as a growth factor

    This article presents the ethical issues in animal research using a combined approach of ethical theory and analysis of scientific findings with bearing on the ethical analysis. The article opens with a general discussion of the moral acceptability of animal use in research. The use of animals...... in research is analyzed from the viewpoint of three distinct ethical approaches: contractarianism, utilitarianism, and animal rights view. On a contractarian view, research on animals is only an ethical issue to the extent that other humans as parties to the social contract care about how research animals...... are faring. From the utilitarian perspective, the use of sentient animals in research that may harm them is an ethical issue, but harm done to animals can be balanced by benefit generated for humans and other animals. The animal rights view, when thoroughgoing, is abolitionist as regards the use of animals...

  7. Immobility reaction at birth in newborn infant. (United States)

    Rousseau, Pierre Victor; Francotte, Jacques; Fabbricatore, Maria; Frischen, Caroline; Duchateau, Delphine; Perin, Marie; Gauthier, Jean-Marie; Lahaye, Willy


    To describe an immobility reaction (IR) that was not previously reported at or immediately after birth in human newborns. We analyzed 31 videos of normal term vaginal deliveries recorded from Time 0 of birth defined as the as the moment that lies between the birth of the thorax and the pelvis of the infant. We searched for perinatal factors associated with newborn's IR. IR at birth was observed in 8 of the 31 newborns. The main features of their behavior were immobilization, frozen face, shallow breathing and bradycardia. One of the 8 newborns had sudden collapse 2h after birth. We found significant relationships between maternal prenatal stress (PS) and IR (p=.037), and a close to significant one between infants' lividness at Time 0 and IR (p=.053). The first breath of the 31 newborns occurred before and was not associated with the first cry (psyndrome. This first report of an IR reaction at birth in human infants could open up new paths for improving early neonatal care. Further research is needed for maternal PS, stress hormones, umbilical cord blood pH measurements in IR newborns. The challenge of education and support for parents of IR newborns is outlined.

  8. Producing Newborn Synchronous Mammalian Cells (United States)

    Gonda, Steve R.; Helmstetter, Charles E.; Thornton, Maureen


    A method and bioreactor for the continuous production of synchronous (same age) population of mammalian cells have been invented. The invention involves the attachment and growth of cells on an adhesive-coated porous membrane immersed in a perfused liquid culture medium in a microgravity analog bioreactor. When cells attach to the surface divide, newborn cells are released into the flowing culture medium. The released cells, consisting of a uniform population of synchronous cells are then collected from the effluent culture medium. This invention could be of interest to researchers investigating the effects of the geneotoxic effects of the space environment (microgravity, radiation, chemicals, gases) and to pharmaceutical and biotechnology companies involved in research on aging and cancer, and in new drug development and testing.

    Jean, D.; Laverty, S.; Halley, J.; Hannigan, D.; Leveille, R.


    In a report describing life ending fractures (255 horses) from the Livestock Disease Diagnostic Center, Kentucky (1993 and 1994), 32 foals had rib fractures. The purpose of our study was to examine the incidence of rib fractures in newborn foals on a Thoroughbred studfarm by physical and radiographic examination, to determine factors which may contribute to the problem and to document any clinical consequences. All foals (263) included were examined within 3 days of birth. The thoracic cage was palpated externally for abnormalities and all foals were placed in dorsal recumbency to evaluate thoracic cage symmetry. Radiographs were used to diagnose foals with thoraciccage asymmetry (TCA) and rib fracture (RF). A diagnosis of costochondral dislocation (CD) was made when no radiographic evidence of fracture was present but there was severe TCA, Fifty-five foals (20.1%) had TCA (9 RF), One to 5 ribs were fractured on 9 of 40 radiographic studies. No consequences of the thoracic trauma was detected clinically, radiographically or ultrasonographically in this group of foals or at a 2- and 4-week follow-up examination. The percentage of foals with a history of abnormal parturition was higher in the TCA foals (15%) compared to the normal foals (6.8%). There weremore primiparous dams in the TCA group than in the normal foal group. Fillies (56.6%) had a higher incidence of birth trauma than colts (43.4%), Thisstudy demonstrates that thoracic trauma is often present in newborn foals and may not always be of clinical significance. Dystocia foals and foals from primiparous mares should be considered high risk for thoracic trauma

  10. Conjunctivitis in the newborn- A comparative study

    Directory of Open Access Journals (Sweden)

    Meenakshi Wadhwani


    Full Text Available Background: Conjunctivitis of the newborn is defined as hyperemia and eye discharge in the neonates and is a common infection occurring in the neonates in the first month of life. In the United States, the incidence of neonatal conjunctivitis ranges from 1-2%, in India, the prevalence is 0.5-33% and varies in the world from 0.9-21% depending on the socioeconomic status. Aim: To study the organisms causing conjunctivitis of the newborn and to correlate the etiology with the mode of delivery. Design: Single center, prospective, observational study. Materials and Methods: A total of 300 mothers and their newborns, born over a period of one year, were included in the study. Of these 200 newborns were delivered through vaginal route (Group A and 100 (Group B delivered by lower segment caesarean section (LSCS. At the time of labour, high vaginal swabs were taken from the mothers. Two conjunctival swabs each from both eyes of the newborn were collected at birth and transported to Microbiology department in a candle jar immediately. Results: Eight babies in Group A, developed conjunctivitis at birth. None of the babies in Group B developed conjunctivitis, this difference was statistically highly significant (P<0.000. The organisms found in the conjunctiva of the newborns in Group A were Coagulase negative Staphylococcus, α hemolytic Streptococcus, Escherichia coli and Pseudomonas spps. However, the commonest organism leading to conjunctivitis in the newborn in this study was Coagulase negative Staphylococcus. It was observed that the mothers of 5 out of 8 babies (60% developing conjunctivitis gave history of midwife interference and premature rupture of membranes so the presence of risk factors contribute to the occurrence of conjunctivitis in the newborn. Conclusions: It is inferred that the mode of delivery and the presence of risk factors is responsible for conjunctivitis in the newborn.

  11. Preventing herpes simplex virus in the newborn. (United States)

    Pinninti, Swetha G; Kimberlin, David W


    Genital herpes simplex virus (HSV) infections are very common worldwide. Approximately 22% of pregnant women are infected genitally with HSV, and most of them are unaware of this. The most devastating consequence of maternal genital herpes is HSV disease in the newborn. Although neonatal HSV infections remain uncommon, due to the significant morbidity and mortality associated with the infection, HSV infection in the newborn is often considered in the differential diagnosis of ill neonates. This review summarizes the epidemiology and management of neonatal HSV infections and discusses strategies to prevent HSV infection in the newborn. Copyright © 2014 Elsevier Inc.

  12. Effect of hematocrit and systolic blood pressure on cerebral blood flow in newborn infants

    International Nuclear Information System (INIS)

    Younkin, D.P.; Reivich, M.; Jaggi, J.L.; Obrist, W.D.; Delivoria-Papadopoulos, M.


    The effects of hematocrit and systolic blood pressure on cerebral blood flow were measured in 15 stable, low birth weight babies. CBF was measured with a modification of the xenon-133 ( 133 Xe) clearance technique, which uses an intravenous bolus of 133 Xe, an external chest detector to estimate arterial 133 Xe concentration, eight external cranial detectors to measure cephalic 133 Xe clearance curves, and a two-compartmental analysis of the cephalic 133 Xe clearance curves to estimate CBF. There was a significant inverse correlation between hematocrit and CBF, presumably due to alterations in arterial oxygen content and blood viscosity. Newborn CBF varied independently of systolic blood pressure between 60 and 84 mm Hg, suggesting an intact cerebrovascular autoregulatory mechanism. These results indicate that at least two of the factors that affect newborn animal CBF are operational in human newborns and may have important clinical implications

  13. Electrographic imaging of recognition memory in 34-38 week gestation intrauterine growth restricted newborns. (United States)

    Black, Linda S; deRegnier, Raye-Ann; Long, Jeffrey; Georgieff, Michael K; Nelson, Charles A


    Electrophysiological imaging of recognition memory using event-related potentials (ERPs) in intrauterine growth-restricted (IUGR) newborns allows assessment of recognition memory before the onset of multiple confounding variables. Animal models that reproduce the physiologic components associated with IUGR have demonstrated adverse effects on the hippocampus, a structure that is essential to normal memory processing. Previous electrophysiologic studies have demonstrated shortened auditory-evoked potential (AEP) and visual-evoked potential (VEP) latencies in IUGR infants suggesting accelerated neural maturation in response to the adverse in-utero environment. The hypothesis of the current study was that newborns with IUGR and head-sparing would demonstrate altered auditory recognition memory when compared to controls and that the configuration of the alteration would evidence advanced maturation but still be different from that of typically grown newborns. Twelve IUGR newborns born at 34-38 weeks gestation with head-sparing and 16 age-matched control newborns were tested with both a speech/nonspeech paradigm to assess auditory sensory processing and a novel (stranger's voice) and familiar (mother's voice) paradigm to assess recognition memory. In the recognition memory experiment, a three-way interaction of condition, lead, and group was identified for the lateral leads T4, CM3, and CM4 with the response to the mother being of much greater area in the IUGR cohort than in the controls. This ERP configuration has previously been reported for the midline leads in term newborns. The findings indicate that IUGR newborns with head-sparing have electrophysiologic evidence of accelerated maturation of cognitive processing suggesting an atypical process of maturation that may not support typical cognitive development.

  20. Newborns from deliveries with epidural anaesthesia

    Directory of Open Access Journals (Sweden)

    Avramović Lidija


    Full Text Available Introduction. The use of epidural anaesthesia in delivery with the purpose to reduce pain and fear in a pregnant woman has the influence on the physiological status of the woman in childbirth and the course of delivery. From the epidural space of the pregnant woman, one part of free anaesthetic comes in the foetal circulation through the mother's circulation and placenta and connects with the foetal proteins. A lower value of albumins and serum proteins in the foetal circulation give bigger free fraction of anaesthetic which is accumulated in the foetal liver, brain and heart full of blood. Objective. The aim of the study was to examine the influence of epidural anaesthesia on the newborn. Methods. Retrospective study of 6,398 documents of newborns was performed in our Clinic of Gynaecology and Obstetrics 'Narodni front' during 2006. The first group was made of 455 newborns from deliveries with epidural anaesthesia and the second was the control group of 5,943 remaining newborns. In both groups we analysed the following: sex, week of gestation, weight, Apgar score, measure of care and resuscitation, perinatal morbidity and then the obtained results were compared. Results. Most of deliveries were vaginal without obstetric intervention (86.6%. The number of deliveries finished with vacuum extractor (4.6% was statistically significantly bigger in the group with epidural anaesthesia than in the control group. Most of the newborns in the first group were born on time (96.5% in 39.0±1.0 week of gestation and with foetal weight 3448±412 grammes. There was no statistical significance in Apgar score between both groups. Epidural anaesthesia does not increase the degree of the newborn's injury. Lower pH of blood was found in the newborns from deliveries with vacuum extractor or operated on (the Ceasarean section. Conclusion. Application of epidural anaesthesia decreases duration of delivery and has no adverse effects on the newborn and hypoxic

  1. Animal Models of Zika Virus (United States)

    Bradley, Michael P; Nagamine, Claude M


    Zika virus has garnered great attention over the last several years, as outbreaks of the disease have emerged throughout the Western Hemisphere. Until quite recently Zika virus was considered a fairly benign virus, with limited clinical severity in both people and animals. The size and scope of the outbreak in the Western Hemisphere has allowed for the identification of severe clinical disease that is associated with Zika virus infection, most notably microcephaly among newborns, and an association with Guillian–Barré syndrome in adults. This recent association with severe clinical disease, of which further analysis strongly suggested causation by Zika virus, has resulted in a massive increase in the amount of both basic and applied research of this virus. Both small and large animal models are being used to uncover the pathogenesis of this emerging disease and to develop vaccine and therapeutic strategies. Here we review the animal-model–based Zika virus research that has been performed to date. PMID:28662753

    Head and face dimensions vary according to race and geographical zone. Hereditary factors also greatly affect the size and shape of the head. There are important medical applications of craniofacial data specific to different racial and ethnic groups. Various cranial and facial anthropometric parameters were assessed in singleton, healthy, full-term newborns of Sikkimese origin in a tertiary care hospital in Sikkim, India. The data were then analysed to determine statistically significant differences between sexes. Forty-five newborns were included in the study. Both male and female newborns were observed to be hyperbrachycephalic and hyperleptoprosopic. The only significant difference between the sexes was in commissural length, which was observed to be greater in male newborns. Craniofacial parameters in Sikkimese newborns vary in comparison with those of other newborns from around the world. Larger studies are needed in order to reveal sex-related variations. Similar studies on various racial groups in North-East India are needed to establish standards for populations with East Asian features.

    Yousaf, U.F.; Hayat, S.


    High risk deliveries are usually associated with increased neonatal mortality and morbidity. Neonatal resuscitation can appreciably affect the outcome in these types of deliveries. Presence of personnel trained in basic neonatal resuscitation at the time of delivery can play an important role in reducing perinatal complications in neonates at risk. The study was carried out to evaluate the effects of newborn resuscitation on neonatal outcome in high risk deliveries. Methods: This descriptive case series was carried out at the Department of Obstetrics and Gynecology, Jinnah Hospital, Lahore. Ninety consecutive high risk deliveries were included and attended by paediatricians trained in newborn resuscitation. Babies delivered by elective Caesarean section, normal spontaneous vaginal deliveries and still births were excluded. Neonatal resuscitation was performed in babies who failed to initiate breathing in the first minute after birth. Data was analyzed using SPSS-16.0. Results: A total of 90 high risk deliveries were included in the study. Emergency caesarean section was the mode of delivery in 94.4% (n=85) cases and spontaneous vaginal delivery in 5.6% (n=5). Preterm pregnancy was the major high risk factor. Newborn resuscitation was required in 37.8% (n=34) of all high risk deliveries (p=0.013). All the new-borns who required resuscitation survived. Conclusion: New-born resuscitation is required in high risk pregnancies and personnel trained in newborn resuscitation should be available at the time of delivery. (author)

    Laz, Alak; Cholakova, Tanya Stefanova; Vrablova, Sofia; Arshad, Naverawaheed


    Animal experimentation is a crucial part of medical science. One of the ways to define it is any scientific experiment conducted for research purposes that cause any kind of pain or suffering to animals. Over the years, the new discovered drugs or treatments are first applied on animals to test their positive outcomes to be later used by humans. There is a debate about violating ethical considerations by exploiting animals for human benefits. However, different ethical theories have been made...

  8. Attitudes toward newborn screening for cytomegalovirus infection. (United States)

    Din, Erica S; Brown, Cedric J; Grosse, Scott D; Wang, Chengbin; Bialek, Stephanie R; Ross, Danielle S; Cannon, Michael J


    Newborns are not routinely screened for cytomegalovirus (CMV), the leading infectious cause of developmental disability. Congenital CMV satisfies a number of criteria for inclusion in newborn screening, and screening potentially offers benefits. Screening could also introduce harms such as anxiety and unnecessary costs for the families of the substantial proportion of CMV-infected children who never develop CMV-related disabilities. Our objective was to assess attitudes toward newborn screening for CMV. We analyzed responses to 5 statements about CMV and newborn screening from 3922 participants in the 2009 HealthStyles survey, a national mail survey designed to include a group similar to the US population with respect to gender, age, race/ethnicity, income, and household size. Two-step cluster analysis was performed to identify clusters of parental attitudes. The majority of respondents strongly or somewhat agreed that they would want to have their newborn tested for CMV even if it was not performed routinely (84%), they had to pay $20 (87%), or CMV-related problems never developed (84%). Nearly half (47%) of them "would worry that the CMV test would lead to unneeded doctor visits and expenses," and 32% "think CMV problems are too rare to worry about." Three clusters of parent respondents were identified on the basis of their attitudes toward CMV screening: "strongly in favor" (31%), "moderately in favor" (49%), and "weakly opposed" (20%). Among most parents, costs, worry, and anxiety associated with newborn screening for CMV would be acceptable. Although attitudes were generally favorable, a minority of the parents were weakly opposed to newborn screening for CMV.

  9. Ethamsylate and lung permeability in ventilated immature newborn rabbits. (United States)

    Amato, M; Sun, B; Robertson, B


    The leakage of proteins in the immature neonatal lung can reduce the effect of exogenous surfactant. The effect of ethamsylate, a more specific prostaglandin inhibitor than indomethacin and aspirin-like drugs, on alveolar albumin leak was studied in a group of 27 immature newborn rabbits (gestational age 27 days). A pilot study was carried out using 4 animals and low-dose ethamsylate (10 mg/kg). A second group of animals (n = 12) received at birth, by intravenous injection, ethamsylate (50 mg/kg) and 10% human albumin (7 ml/kg). Animals not receiving ethamsylate (n = 11) served as control group. After 30 min of artificial ventilation with standard tidal volume (10 ml/kg) the lungs were lavaged and the amount of human albumin in lung lavage fluid was determined by immunodiffusion. No statistically significant differences were found in lung-thorax compliance and vascular to alveolar albumin leak between ethamsylate-treated animals and controls (p > 0.5). However, there was a statistically significant negative correlation between protein leak and lung compliance (r = -0.41; p ethamsylate administration on neonatal lung permeability in the immature neonate confirming that lung permeability is inversely related to compliance.

    Full Text Available Research Problem: What are the factors responsible for fungal colonization in newborns? Objective: To study the pattern of and predisposing fac­tors for the development of superficial candidiasis and fungal colonization in the newborns. Study Design: Prospective study. Setting: Neonatology unitof the Paediatrics department of a teaching hospital. Participants: Randomly selected pregnant mothers admit­ted to the maternity ward and the newborns delivered to them. Sample Size: 120 pregnant mothers and the newborns delivered. Study Variables: Candida, Site of colonization. Statistical Analysis: By tests of significance Results: Candida was isolated from 23 (19.16% infants on the first day increasing to 52 (43.33% infants on the sixth day. The most common site of colonization was oral cavity. Candida colonization was more common in prema­ture infants (p<0.05. Oral thrush was seen in 29 (24.17% infants during the study and a significant number of these infants showed colonization from the first day of life. Conclusions: Fungal colonization of the newborns due to Candida species is quite common, and in the first week of life predominantly occurred in the ora I cavity. Superficial clinical candidiasis, especially oral thrush is more common in those colonized on the first day of life.

    The mechanisms controlling pain in newborns during delivery are poorly understood. We explored the hypothesis that oxytocin, an essential hormone for labor and a powerful neuromodulator, exerts analgesic actions on newborns during delivery. Using a thermal tail-flick assay, we report that pain sensitivity is two-fold lower in rat pups immediately after birth than 2 days later. Oxytocin receptor antagonists strongly enhanced pain sensitivity in newborn, but not in 2-day-old rats, whereas oxytocin reduced pain at both ages suggesting an endogenous analgesia by oxytocin during delivery. Similar analgesic effects of oxytocin, measured as attenuation of pain-vocalization induced by electrical whisker pad stimulation, were also observed in decerebrated newborns. Oxytocin reduced GABA-evoked calcium responses and depolarizing GABA driving force in isolated neonatal trigeminal neurons suggesting that oxytocin effects are mediated by alterations of intracellular chloride. Unlike GABA signaling, oxytocin did not affect responses mediated by P2X3 and TRPV1 receptors. In keeping with a GABAergic mechanism, reduction of intracellular chloride by the diuretic NKCC1 chloride co-transporter antagonist bumetanide mimicked the analgesic actions of oxytocin and its effects on GABA responses in nociceptive neurons. Therefore, endogenous oxytocin exerts an analgesic action in newborn pups that involves a reduction of the depolarizing action of GABA on nociceptive neurons. Therefore, the same hormone that triggers delivery also acts as a natural pain killer revealing a novel facet of the protective actions of oxytocin in the fetus at birth. PMID:21519396

    Soubry Adelheid


    Full Text Available Abstract Background Data from epidemiological and animal model studies suggest that nutrition during pregnancy may affect the health status of subsequent generations. These transgenerational effects are now being explained by disruptions at the level of the epigenetic machinery. Besides in vitro environmental exposures, the possible impact on the reprogramming of methylation profiles at imprinted genes at a much earlier time point, such as during spermatogenesis or oogenesis, has not previously been considered. In this study, our aim was to determine associations between preconceptional obesity and DNA methylation profiles in the offspring, particularly at the differentially methylated regions (DMRs of the imprinted Insulin-like Growth Factor 2 (IGF2 gene. Methods We examined DNA from umbilical cord blood leukocytes from 79 newborns, born between July 2005 and November 2006 at Duke University Hospital, Durham, NC. Their mothers participated in the Newborn Epigenetics Study (NEST during pregnancy. Parental characteristics were obtained via standardized questionnaires and medical records. DNA methylation patterns at two DMRs were analyzed by bisulfite pyrosequencing; one DMR upstream of IGF2 (IGF2 DMR, and one DMR upstream of the neighboring H19 gene (H19 DMR. Multiple regression models were used to determine potential associations between the offspring's DNA methylation patterns and parental obesity before conception. Obesity was defined as body mass index (BMI ≥30 kg/m2. Results Hypomethylation at the IGF2 DMR was associated with paternal obesity. Even after adjusting for several maternal and newborn characteristics, we observed a persistent inverse association between DNA methylation in the offspring and paternal obesity (β-coefficient was -5.28, P = 0.003. At the H19 DMR, no significant associations were detected between methylation patterns and paternal obesity. Our data suggest an increase in DNA methylation at the IGF2 and H19 DMRs among

  14. Neurotransmitter properties of the newborn human retina

    International Nuclear Information System (INIS)

    Hollyfield, J.G.; Frederick, J.M.; Rayborn, M.E.


    Human retinal tissue from a newborn was examined autoradiographically for the presence of high-affinity uptake and localization of the following putative neurotransmitters: dopamine, glycine, GABA, aspartate, and glutamate. In addition, the dopamine content of this newborn retina was measured by high pressure liquid chromatography. Our study reveals that specific uptake mechanisms for 3 H-glycine, 3 H-dopamine, and 3 H-GABA are present at birth. However, the number and distribution of cells labeled with each of these 3 H-transmitters are not identical to those observed in adult human retinas. Furthermore, the amount of endogenous dopamine in the newborn retina is approximately 1/20 the adult level. Photoreceptor-specific uptake of 3 H-glutamate and 3 H-aspartate are not observed. These findings indicate that, while some neurotransmitter-specific properties are present at birth, significant maturation of neurotransmitter systems occurs postnatally

    To investigate the therapeutic effects of bronchoalveolar lavage (BAL) with either diluted surfactant (SBAL) or perfluorochemical liquid (PBAL), followed by either conventional mechanical ventilation (CMV) or partial liquid ventilation (PLV), on lung injury and proinflammatory cytokine production induced by meconium aspiration in newborn piglets. A prospective, randomized, experimental study. An animal research laboratory at a medical center. Anesthetized and mechanically ventilated newborn piglets (n = 27). The animals were instilled with 3-5 mL/kg 25% human meconium via an endotracheal tube to induce meconium aspiration syndrome (MAS). After stabilization, animals were randomly assigned to either CMV group (no BAL) or one of the treatment groups (SBAL-CMV, SBAL-PLV, PBAL-CMV, and PBAL-PLV). Cardiopulmonary variables were monitored, and interleukin-1beta and interleukin-6 content of the serum and lung tissue was measured. The animals without any treatment (CMV group) displayed the worst outcome; the animals in the PBAL-PLV group had the best gas exchange, lung compliance, and least pulmonary damage; and the SBAL-CMV, PBAL-CMV, and SBAL-PLV groups had intermediate effects. The serum interleukin-1beta concentration of the CMV group was significantly higher than all other groups over time (p CMV group and lowest in the PBAL-PLV group. Initial therapeutic BAL and therapeutic BAL followed by PLV with the same perfluorochemical liquid provided significant therapeutic effects in treating an animal model with severe MAS and therefore warrant consideration in cases that are intractable to other therapies.

  6. Immunological gap in the infectious animal model for biliary atresia. (United States)

    Czech-Schmidt, G; Verhagen, W; Szavay, P; Leonhardt, J; Petersen, C


    Extrahepatic biliary atresia (EHBA), the etiology of which still remains unclear, occurs exclusively in newborns and has recently been simulated in an animal model. It is possible to trigger an EHBA corresponding to the human disease by means of intraperitoneal infection of newborn Balb/c mice with rhesus rotavirus (RRV). The aim of the present study was to determine the conditions and circumstances for inducing biliary atresia in this model focusing on first-line immunological aspects. Newborn as well as pregnant Balb/c mice were intraperitoneally infected with RRV. The highest incidence of cholestasis (86%) was achieved by infection with 10(6) PFU/ml RRV within the first 12 h postpartum, resulting in EHBA with a lethality of 100%. However, the later the newborn mouse is infected, the less likelihood there is that EHBA is triggered. Additionally, the incidence of biliary atresia in this model depends on the quantity of the virus that is given intraperitoneally. However, the development of biliary atresia is not correlated to the virus in the liver. The antepartum infection of pregnant mice does not induce EHBA in the offspring. Female mice that are immunized against RRV protect their newborns from developing RRV-induced cholestasis and EHBA. This protection is transmitted transplacentally and not by breast milk. It is obvious that a temporary immunological gap is essential for virally induced EHBA. Further studies should focus on specific parameters of the immune system of newborn mice in this biliary atresia model. Copyright 2001 Academic Press.

  7. Animal experimentation. (United States)

    Kolar, Roman


    Millions of animals are used every year in often times extremely painful and distressing scientific procedures. Legislation of animal experimentation in modern societies is based on the supposition that this is ethically acceptable when certain more or less defined formal (e.g. logistical, technical) demands and ethical principles are met. The main parameters in this context correspond to the "3Rs" concept as defined by Russel and Burch in 1959, i.e. that all efforts to replace, reduce and refine experiments must be undertaken. The licensing of animal experiments normally requires an ethical evaluation process, often times undertaken by ethics committees. The serious problems in putting this idea into practice include inter alia unclear conditions and standards for ethical decisions, insufficient management of experiments undertaken for specific (e.g. regulatory) purposes, and conflicts of interest of ethics committees' members. There is an ongoing societal debate about ethical issues of animal use in science. Existing EU legislation on animal experimentation for cosmetics testing is an example of both the public will for setting clear limits to animal experiments and the need to further critically examine other fields and aspects of animal experimentation.

  12. Preventing newborn deaths due to prematurity. (United States)

    Azad, Kishwar; Mathews, Jiji


    Preterm births (PTBs), defined as births before 37 weeks of gestation account for the majority of deaths in the newborn period. Prediction and prevention of PTB is challenging. A history of preterm labour or second trimester losses and accurate measurement of cervical length help to identify women who would benefit from progesterone and cerclage. Fibronectin estimation in the cervicovaginal secretions of a symptomatic woman with an undilated cervix can predict PTB within 10 days of testing. Antibiotics should be given to women with preterm prelabour rupture of membranes but tocolysis has a limited role in the management of preterm labour. Antenatal corticosteroids to prevent complications in the neonate should be given only when gestational age assessment is accurate PTB is considered imminent, maternal infection and the preterm newborn can receive adequate care. Magnesium sulphate for fetal neuroprotection should be given when delivery is imminent. After birth, most babies respond to simple interventions essential newborn care, basic care for feeding support, infections and breathing difficulties. Newborns weighing 2000 g or less, benefit from KMC. Babies, who are clinically unstable or cannot be given KMC may be nursed in an incubator or under a radiant warmer. Treatment modalities include oxygen therapy, CPAP, surfactant and assisted ventilation. Copyright © 2016. Published by Elsevier Ltd.

  17. Diagnostic value of newborn foot length to predict gestational age

    Directory of Open Access Journals (Sweden)

    Mutia Farah Fawziah


    Full Text Available Background  Identification of gestational age, especially within 48 hours of birth, is crucial for newborns, as the earlier preterm status is detected, the earlier the child can receive optimal management. Newborn foot length is an anthropometric measurement which is easy to perform, inexpensive, and potentially efficient for predicting gestational age. Objective  To analyze the diagnostic value of newborn foot length in predicting gestational age. Methods  This diagnostic study was performed between October 2016 and February 2017 in the High Care Unit of Neonates at Dr. Moewardi General Hospital, Surakarta. A total of 152 newborns were consecutively selected and underwent right foot length measurements before 96 hours of age. The correlation between newborn foot length to classify as full term and gestational age was analyzed with Spearman’s correlation test because of non-normal data distribution. The cut-off point of newborn foot length was calculated by receiver operating characteristic (ROC curve and diagnostic values of newborn foot length were analyzed by 2 x 2 table with SPSS 21.0 software. Results There were no significant differences between male and female newborns in terms of gestational age, birth weight, choronological age, and newborn foot length (P>0.05. Newborn foot length and gestational age had a significant correlation (r=0.53; P=0.000. The optimal cut-off newborn foot length to predict full term status was 7.1 cm. Newborn foot length below 7.1 cm had sensitivity 75%, specificity 98%, positive predictive value 94.3%, negative predictive value 90.6%, positive likelihood ratio 40.5, negative likelihood ratio 0.25, and post-test probability 94.29%, to predict preterm status in newborns. Conclusion  Newborn foot length can be used to predict gestational age, especially for the purpose of differentiating between preterm and full term newborns.

  18. Diuretics for transient tachypnoea of the newborn. (United States)

    Kassab, Manal; Khriesat, Wadah M; Anabrees, Jasim


    Transient tachypnoea of the newborn (TTN) results from delayed clearance of lung liquid and is a common cause of admission of full-term infants to neonatal intensive care units. The condition is particularly common after elective caesarean section. Conventional treatment involves appropriate oxygen administration and continuous positive airway pressure in some cases. Most infants receive antibiotic therapy. Hastening the clearance of lung liquid may shorten the duration of the symptoms and reduce complications. To determine whether diuretic administration reduces the duration of oxygen therapy and respiratory symptoms and shortens hospital stay in term infants presenting with transient tachypnoea of the newborn. An updated search was carried out in September 2015 of the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library issue 9, 2015), MEDLINE via Ovid, EMBASE, PubMed, and CINAHL via OVID. We included randomised and quasi-randomised controlled trials that compared the effect of diuretics administration versus placebo or no treatment in infants of less than seven days of age, born at 37 or more weeks of gestation with the clinical picture of transient tachypnoea of the newborn. We extracted and analysed data according to the methods outlined in the latest Cochrane Handbook for Systematic Reviews of Interventions. Two review authors assessed trial quality in each potentially eligible manuscript and two review authors extracted data. Our previous systematic review included two trials enrolling a total of 100 infants with transient tachypnoea of the newborn (Wiswell 1985; Karabayir 2006). The updated search revealed no new trials. Wiswell 1985 randomised 50 infants to receive either oral furosemide (2 mg/kg body weight at time of diagnosis followed by a 1 mg/kg dose 12 hours later if the tachypnoea persisted) or placebo. Karabayir 2006 randomised 50 infants to receive either intravenous furosemide (2 mg/kg body

    Gillette, E.L.


    There are few trained veterinary radiation oncologists and the expense of facilities has limited the extent to which this modality is used. In recent years, a few cobalt teletherapy units and megavoltage x-ray units have been employed in larger veterinary institutions. In addition, some radiation oncologists of human medical institutions are interested and willing to cooperate with veterinarians in the treatment of animal tumors. Carefully designed studies of the response of animal tumors to new modalities serve two valuable purposes. First, these studies may lead to improved tumor control in companion animals. Second, these studies may have important implications to the improvement of therapy of human tumors. Much remains to be learned of animal tumor biology so that appropriate model systems can be described for such studies. Many of the latter studies can be sponsored by agencies interested in the improvement of cancer management

    Kasperbauer, Tyler Joshua


    Ethicists have tended to treat the psychology of attributing mental states to animals as an entirely separate issue from the moral importance of animals’ mental states. In this paper I bring these two issues together. I argue for two theses, one descriptive and one normative. The descriptive thesis...... holds that ordinary human agents use what are generally called phenomenal mental states (e.g., pain and other emotions) to assign moral considerability to animals. I examine recent empirical research on the attribution of phenomenal states and agential states (e.g., memory and intelligence) to argue...... that phenomenal mental states are the primary factor, psychologically, for judging an animal to be morally considerable. I further argue that, given the role of phenomenal states in assigning moral considerability, certain theories in animal ethics will meet significant psychological resistance. The normative...

  3. Newborn hearing screening protocol in tuscany region. (United States)

    Berrettini, Stefano; Ghirri, Paolo; Lazzerini, Francesco; Lenzi, Giovanni; Forli, Francesca


    Newborn hearing screening has to be considered the first step of a program for the identification, diagnosis, treatment and habilitation/rehabilitation of children with hearing impairment. In Tuscany Region of Italy, the universal newborn hearing screening is mandatory since november 2007. The first guidelines for the execution of the screening have been released in June 2008; then many other Italian regions partially or totally adopted these guidelines. On the basis of the experience from 2008 and according to the recent evidences in the scientific literature, a new screening protocol was released in Tuscany region. The new protocol is an evolution of the previous one. Some issues reported in the previous protocol and in the Joint Committee on Infant Hearing statement published in 2007 were revised, such as the risk factors for auditory neuropathy and for late onset, progressive or acquired hearing loss. The new updated guidelines were submitted to the Sanitary Regional Council and then they have been approved in August 2016. The updated screening protocol is mainly aimed to identify newborns with a congenital moderate-to-profound hearing loss, but it also provides indications for the audiological follow-up of children with risk's factor for progressive or late onset hearing loss; further it provides indications for the audiological surveillance of children at risk for acquired hearing impairment. Then, in the new guidelines the role of the family paediatrician in the newborn hearing screening and audiological follow-up and surveillance is underscored. Finally the new guidelines provide indications for the treatment with hearing aids and cochlear implant, in accordance with the recent Italian Health Technology Assessment (HTA) guidelines. In the paper we report the modality of execution of the universal newborn hearing screening in the Tuscany Region, according to the recently updated protocol. The main features of the protocol and the critical issues are

    Mutations in the human ABCA3 gene, encoding an ABC-transporter, are associated with respiratory failure in newborns and pediatric interstitial lung disease. In order to study disease mechanisms, a transgenic mouse model with a disrupted Abca3 gene was generated by targeting embryonic stem cells. While heterozygous animals developed normally and were fertile, individuals homozygous for the altered allele (Abca3-/-) died within one hour after birth from respiratory failure, ABCA3 protein being undetectable. Abca3-/- newborns showed atelectasis of the lung in comparison to a normal gas content in unaffected or heterozygous littermates. Electron microscopy demonstrated the absence of normal lamellar bodies in type II pneumocytes. Instead, condensed structures with apparent absence of lipid content were found. We conclude that ABCA3 is required for the formation of lamellar bodies and lung surfactant function. The phenotype of respiratory failure immediately after birth corresponds to the clinical course of severe ABCA3 mutations in human newborns

    Pneumothorax is a common emergency affecting extremely preterm. In adult studies, lung ultrasound has performed better than chest x-ray in the diagnosis of pneumothorax. The purpose of this study was to determine the efficacy of lung ultrasound (LUS) examination to detect pneumothorax using a preterm animal model. This was a prospective, observational study using newborn Border-Leicester lambs at gestational age = 126 days (equivalent to gestational age = 26 weeks in humans) receiving mechanical ventilation from birth to 2 h of life. At the conclusion of the experiment, LUS was performed, the lambs were then euthanised and a post-mortem exam was immediately performed. We used previously published ultrasound techniques to identify pneumothorax. Test characteristics of LUS to detect pneumothorax were calculated, using the post-mortem exam as the 'gold standard' test. Nine lambs (18 lungs) were examined. Four lambs had a unilateral pneumothorax, all of which were identified by LUS with no false positives. This was the first study to use post-mortem findings to test the efficacy of LUS to detect pneumothorax in a newborn animal model. Lung ultrasound accurately detected pneumothorax, verified by post-mortem exam, in premature, newborn lambs. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

  10. Maternal anti-M induced hemolytic disease of newborn followed by prolonged anemia in newborn twins. (United States)

    Arora, Satyam; Doda, Veena; Maria, Arti; Kotwal, Urvershi; Goyal, Saurabh


    Allo-anti-M often has an immunoglobulin G (IgG) component but is rarely clinically significant. We report a case of hemolytic disease of the fetus and newborn along with prolonged anemia in newborn twins that persisted for up to 70 days postbirth. The aim was to diagnose and successfully manage hemolytic disease of newborn (HDN) due to maternal alloimmunization. Direct antiglobulin test (DAT), antigen typing, irregular antibody screening and identification were done by polyspecific antihuman globulin cards and standard tube method. At presentation, the newborn twins (T1, T2) had HDN with resultant low reticulocyte count and prolonged anemia, which continued for up to 70 days of life. Blood group of the twins and the mother was O RhD positive. DAT of the both newborns at birth was negative. Anti-M was detected in mothers as well as newborns. Type of antibody in mother was IgG and IgM type whereas in twins it was IgG type only. M antigen negative blood was transfused thrice to twin-1 and twice to twin-2. Recurring reduction of the hematocrit along with low reticulocyte count and normal other cell line indicated a pure red cell aplastic state. Anti-M is capable of causing HDN as well as prolonged anemia (red cell aplasia) due to its ability to destroy the erythroid precursor cells. Newborns with anemia should be evaluated for all the possible causes to establish a diagnosis and its efficient management. Mother should be closely monitored for future pregnancies as well.

    The chapter evaluates results of toxicological studies on experimental animals to investigate health effects of air pollutants and examines the animal data have predicted the response to human subject. Data are presented on the comparative toxicity of sulfur dioxide and sulfuric acid. The animal data obtained by measurement of airway resistance in guinea pigs and of bronchial clearance of particles in donkeys predicted clearly that sulfuric acid was more irritant than sulfur dioxide. Data obtained on human subjects confirmed this prediction. These acute studies also correctly predicted the comparative toxicity of the two compounds in two year studies of monkeys. Such chronic studies are not possible in human subjects but it is a reasonable to assume that sulfuric acid would be more toxic than sulfur dioxide. Current findings in epidemiological studies certainly support this assumption.

  14. Mother and newborn baby: mutual regulation of physiology and behavior--a selective review. (United States)

    Winberg, Jan


    This article reviews 30 years of work demonstrating that interactions between mother and newborn infant in the period just after birth influence the physiology and behavior of both. Close body contact of the infant with his/her mother helps regulate the newborn's temperature, energy conservation, acid-base balance, adjustment of respiration, crying, and nursing behaviors. Similarly, the baby may regulate--i.e., increase--the mother's attention to his/her needs, the initiation and maintenance of breastfeeding, and the efficiency of her energy economy through vagus activation and a surge of gastrointestinal tract hormone release resulting in better exploitation of ingested calories. The effects of some of these changes can be detected months later. Parallels to animal research and possible mechanisms are discussed.

  15. [Newborn children under phototherapy: the mother's perception]. (United States)

    Campos, Antonia do Carmo Soares; Cardoso, Maria Vera Lúcia Moreira Leitão


    Since 1958, phototherapy has been used as a method to cure jaundice, which is still an important disease in newborn children. Supported by a phenomenological and qualitative approach, this study aims to investigate the mothers' perception of the phototherapy treatment their children are submitted to. Research subjects were ten mothers of newborns under phototherapy treatment at the Neonatological Hospitalization Unit of a public maternity in Fortaleza-CE, Brazil. Data were collected between May and July 2002. We used group meetings with the mothers as suggested by Carl Rogers. Discourse was organized into categories according to Bardin, which revealed themes that were analyzed in view of Paterson's and Zderad's humanistic nursing theory, as follows: mothers' knowledge on phototherapy and concerns about the treatment. We concluded that the analyzed mothers' major concern is related to the babies' vision.

  1. Diabetes mellitus in newborns and infants. (United States)

    Menon, P S; Khatwa, U A


    Diabetes mellitus is uncommon in infancy and newborn period. The two common forms seen are the transient and permanent forms of diabetes mellitus of the newborn. They have to be differentiated from the transient hyperglycemic states (Blood sugar > 125 mg/dl) seen in newborns who receive parenteral glucose infusions and in those with septicemia and CNS disorders. Transient diabetes mellitus of the newborn (TDNB) is defined as hyperglycemia occurring within the first month of life lasting at least 2 weeks and requiring insulin therapy. Most of these cases resolve spontaneously by 4 months. It has a reported incidence of 1 in 45,000 to 60,000 live births. The most likely etiology is a maturational delay of cAMP mediated insulin release. The clinical features include small for datedness, proneness for birth asphyxia, open-eye alert facies, dehydration, emaciation, polyuria and poydipsia. These children are prone to septicemia and urinary tract infections. They have hyperglycemia, glucosuria, absent or mild ketonuria, low basal insulin, C-peptide and IGF-1 levels. Treatment consists of hydration and judicious administration of insulin with close monitoring. Thirty percent of these children are likely to develop permanent neonatal diabetes. Compared to transient form, permanent diabetes mellitus is uncommon. It is usually due to pancreatic dysgenesis often associated with other malformations and rarely due to type 1 diabetes mellitus. The diagnosis is based on the demonstration of both exocrine and endocrine pancreatic dysfunction. These children are managed as type 1 diabetes mellitus. They are prone to develop the vascular complications of diabetes at an earlier date.

    Full Text Available This report details the management of a newborn with nesidioblastosis who underwent a 95% pancreatectomy under general anaesthesia. The baby presented with hypoglycemic convulsions, due to hyperinsulinism, and was treated with 12.5% dextrose infusions, glucagon and anticonvulsants. Intraoperatively and postoperatively the baby remained hyperglycemic. A postoperative osmotic diuresis necessitated the use of insulin for brief period. The infant remained euglycemic and convulsion free, following discontinuation of the dextrose infusions and starting of oral feeds. Recovery was uneventful.

  5. Body composition of term healthy Indian newborns. (United States)

    Jain, V; Kurpad, A V; Kumar, B; Devi, S; Sreenivas, V; Paul, V K


    Previous anthropometry-based studies have suggested that in Indian newborns fat mass is conserved at the expense of lean tissue. This study was undertaken to assess the body composition of Indian newborns and to evaluate its relation with parents' anthropometry, birth weight and early postnatal weight gain. Body composition of healthy term singleton newborns was assessed by the deuterium dilution method in the second week of life. Anthropometry was carried out at birth and on the day of study. Data from 127 babies were analyzed. Birth weight was 2969±383 g. Body composition was assessed at a mean age of 12.7±3.1 days. Fat and fat-free mass were 354±246 and 2764±402 g, respectively, and fat mass percentage (FM%) was 11.3±7.3%. Birth weight and fat-free mass were higher among boys, but no gender difference was noted in FM%. Birth weight was positively correlated with fat as well as fat-free mass but not FM%. FM% showed positive correlation with gain in weight from birth to the day of assessment. This is the first study from India to report body composition in newborns using deuterium dilution. FM% was comparable to that reported for Western populations for babies of similar age. Our results suggest that the percentage of fat and fat-free mass is relatively constant over the range of birth weights included in this study, and greater weight gain during early postnatal period results in greater increase in FM%.

    Acquired subglottic stenosis in a newborn is often associated with prolonged endotracheal intubation. This condition is generally diagnosed during operative endoscopy after airway injury has occurred. Unfortunately, endoscopy is unable to characterize the submucosal changes observed in such airway injuries. Other modalities, such as magnetic resonance imaging, computed tomography, and ultrasound, do not possess the necessary level of resolution to differentiate scar, neocartilage, and edema. Optical coherence tomography (OCT) is an imaging modality that produces high-resolution, cross-sectional images of living tissue (8 to 20 microm). We examined the ability of this noninvasive technique to characterize the newborn airway in a prospective clinical trial. Twelve newborn patients who required ventilatory support underwent OCT airway imaging. Comparative analysis of intubated and non-intubated states was performed. Imaging of the supraglottis, glottis, subglottis, and trachea was performed in 12 patients, revealing unique tissue characteristics as related to turbidity, signal backscattering, and architecture. Multiple structures were identified, including the vocal folds, cricoid cartilage, tracheal rings, ducts, glands, and vessels. Optical coherence tomography clearly identifies in vivo tissue layers and regional architecture while offering detailed information concerning tissue microstructures. The diagnostic potential of this technology makes OCT a promising modality in the study and surveillance of the neonatal airway.

    Full Text Available A biotecnologia animal tem fornecido novas ferramentas para os programas de melhoramento e, dessa forma, contribuído para melhorar a eficiência da produção dos produtos de origem animal. No entanto, os avanços têm sido mais lentos do que antecipados, especialmente em razão da dificuldade na identificação dos genes responsáveis pelas características fenotípicas de interesse zootécnico. Três estratégias principais têm sido utilizadas para identificar esses genes - mapeamento de QTL, genes candidatos e sequenciamento de DNA e mRNA - e cada uma tem suas vantagens e limitações. O mapeamento de QTL permite determinar as regiões genômicas que contêm genes, mas o intervalo de confiança do QTL pode ser grande e conter muitos genes. A estratégia de genes candidatos é limitada por causa do conhecimento ainda restrito das funções de todos os genes. Os sequenciamentos de genomas e de sequências expressas podem auxiliar na identificação da posição de genes e de vias metabólicas associadas à característica de interesse. A integração dessas estratégias por meio do desenvolvimento de programas de bioinformática permitirá a identificação de novos genes de interesse zootécnico. Assim, os programas de melhoramento genético se beneficiarão pela inclusão da informação obtida diretamente do DNA na avaliação do mérito genético dos plantéis disponíveis.Animal biotechnology is providing new tools for animal breeding and genetics and thus contributing to advances in production efficiency and quality of animal products.

    Full Text Available Neonatal encephalopathy following birth asphyxia is a major predictor of long-term neurological impairment. Therapeutic hypothermia is currently the standard of care to prevent brain injury in asphyxiated newborns but is not protective in all cases. More robust and versatile treatment options are needed. Angiogenesis is a demonstrated therapeutic target in adult stroke. However, no systematic study examines the expression of angiogenesis-related markers following birth asphyxia in human newborns.This study aimed to evaluate the expression of angiogenesis-related protein markers in asphyxiated newborns developing and not developing brain injury compared to healthy control newborns.Twelve asphyxiated newborns treated with hypothermia were prospectively enrolled; six developed eventual brain injury and six did not. Four healthy control newborns were also included. We used Rules-Based Medicine multi-analyte profiling and protein array technologies to study the plasma concentration of 49 angiogenesis-related proteins. Mean protein concentrations were compared between each group of newborns.Compared to healthy newborns, asphyxiated newborns not developing brain injury showed up-regulation of pro-angiogenic proteins, including fatty acid binding protein-4, glucose-6-phosphate isomerase, neuropilin-1, and receptor tyrosine-protein kinase erbB-3; this up-regulation was not evident in asphyxiated newborns eventually developing brain injury. Also, asphyxiated newborns developing brain injury showed a decreased expression of anti-angiogenic proteins, including insulin-growth factor binding proteins -1, -4, and -6, compared to healthy newborns.These findings suggest that angiogenesis pathways are dysregulated following birth asphyxia and are putatively involved in brain injury pathology and recovery.

  11. Monitoring of newborns at high risk for brain injury


    Pisani, Francesco; Spagnoli, Carlotta


    Due to the increasing number of surviving preterm newborns and to the recognition of therapeutic hypothermia as the current gold standard in newborns with hypoxic-ischaemic encephalopathy, there has been a growing interest in the implementation of brain monitoring tools in newborns at high risk for neurological disorders. Among the most frequent neurological conditions and presentations in the neonatal period, neonatal seizures and neonatal status epilepticus, paroxysmal non-epileptic motor p...

    Background Neonatal encephalopathy following birth asphyxia is a major predictor of long-term neurological impairment. Therapeutic hypothermia is currently the standard of care to prevent brain injury in asphyxiated newborns but is not protective in all cases. More robust and versatile treatment options are needed. Angiogenesis is a demonstrated therapeutic target in adult stroke. However, no systematic study examines the expression of angiogenesis-related markers following birth asphyxia in human newborns. Objective This study aimed to evaluate the expression of angiogenesis-related protein markers in asphyxiated newborns developing and not developing brain injury compared to healthy control newborns. Design/Methods Twelve asphyxiated newborns treated with hypothermia were prospectively enrolled; six developed eventual brain injury and six did not. Four healthy control newborns were also included. We used Rules-Based Medicine multi-analyte profiling and protein array technologies to study the plasma concentration of 49 angiogenesis-related proteins. Mean protein concentrations were compared between each group of newborns. Results Compared to healthy newborns, asphyxiated newborns not developing brain injury showed up-regulation of pro-angiogenic proteins, including fatty acid binding protein-4, glucose-6-phosphate isomerase, neuropilin-1, and receptor tyrosine-protein kinase erbB-3; this up-regulation was not evident in asphyxiated newborns eventually developing brain injury. Also, asphyxiated newborns developing brain injury showed a decreased expression of anti-angiogenic proteins, including insulin-growth factor binding proteins -1, -4, and -6, compared to healthy newborns.

    Li, Amanda M; Chau, Vann; Poskitt, Kenneth J; Sargent, Michael A; Lupton, Brian A; Hill, Alan; Roland, Elke; Miller, Steven P


    White matter injury (WMI) is the characteristic pattern of brain injury detected on magnetic resonance imaging in the premature newborn. Focal noncystic WMI is increasingly recognized in populations of term newborns. The aim of this study was to describe the occurrence of focal noncystic WMI in a cohort of 48 term newborns with encephalopathy studied with magnetic resonance imaging at 72 +/- 12 h of life, and to identify clinical risk factors for this pattern of injury. Eleven newborns (23%; 95% CI 11-35) were found to have WMI (four minimal, three moderate, and four severe). In 10 of the 11 newborns, the WMI was associated with restricted diffusion on apparent diffusion coefficient maps. An increasing severity of WMI was associated with lower gestational age at birth (p = 0.05), but not lower birth weight. Newborns with WMI had milder encephalopathy and fewer clinical seizures relative to other newborns in the cohort. Other brain injuries were seen in three of the 11 newborns: basal nuclei predominant pattern of injury in one and cortical strokes in two. These findings suggest that WMI in the term newborn is acquired near birth and that the state of brain maturation is an important determinant of this pattern of brain injury.

  17. Quality maternal and newborn care to ensure a healthy start for every newborn in the World Health Organization Western Pacific Region. (United States)

    Obara, H; Sobel, H


    In the World Health Organization Western Pacific Region, the high rates of births attended by skilled health personnel (SHP) do not equal access to quality maternal or newborn care. 'A healthy start for every newborn' for 23 million annual births in the region means that SHP and newborn care providers give quality intrapartum, postpartum and newborn care. WHO and the UNICEF Regional Action Plan for Healthy Newborn Infants provide a platform for countries to scale-up Early Essential Newborn Care (EENC). The plan emphasises the creation of an enabling environment for the practice of EENC; thereby, preventing 50,000 newborn deaths annually. © 2014 Royal College of Obstetricians and Gynaecologists.

    Full Text Available Background: Quality of services provided by health care provider, the closest health functionary to the community has impact on neonatal mortality. Aims: Study on quality of newborn care in rural areas.  Settings and Design: This is a prospective study in the field practice areas of J.N. Medical College and areas under primary health centre of public health care system in Wardha district.  Methods and Material: Modified quality check list on the basis of PHC MAP module guidelines for assessing the quality of service-module 6-user’s guide was prepared. Face to face interview with 205 (group-A/104 nos + group-B/101 nos mother of newborn was method to collected information in three postnatal visits.  Statistical analysis: Quality (verbal response of each service was quantified as acceptable, average and worst.  Quality of both the groups was compared by calculating P-value after utilizing Z-test.  Results: Over all acceptable quality of medical history was 30.03%, physical examination was 21.73%, preventive service was 91.17% and counseling was 24.83%. Significant difference between two groups were found on history taking for (cry, breathing and body movement of baby, recording weight and counseling regarding exclusive breast feeding for first 6 month of life. Worst quality in this study were observed in history for anything applying to eyes, umbilical cord stump and complication of baby for which appropriate management was taken. Except for weight recording and examination of head and fontanels all other variables under physical examination were not acceptable. Counseling regarding high risk condition of baby was only 13.66%. Conclusion: Existing newborn services except immunization is inadequate and needs to be strengthened especially physical examination and counseling services. 

  19. ABO incompatibility hemolytic disease following exchange transfusion 96 newborn

    Khatami S.F


    Full Text Available Background: ABO incompatibility hemolytic disease of the newborn is a common cause of clinical jaundice and causes two-thirds of the hemolytic disease in newborns. This study was undertaken to determine the frequency of ABO incompatibility hemolytic disease and its complications in newborns undergoing exchange transfusion.Methods: This prospective and descriptive study was performed in jaundiced newborn infants during a three-year period. Inclusion criteria were: maternal blood type O, newborn blood type A or B, rising indirect hyperbilirubinemia in the first two days of life, positive immunohematologic test for newborns and exchange transfusion. Exclusion criteria were: incomplete information, other accompanying diseases that induce hyperbilirubinemia. All newborn infants received phototherapy before and after exchange transfusion. We did not use intravenous immunoglobulin, hemoxygenase inhibitor drugs and blood products before exchange transfusion.Results: Double-volume exchange transfusion via umbilical cord catheter was performed in 96 patients, 19 (20% of whom suffered from ABO incompatibility. Of these 19 newborns, two-thirds (13 were preterm infants. The minimum level of serum bilirubin was 10 mg/dl and the maximum serum bilirubin level was 35 mg/dl. In six patients (32% serum bilirubin levels were >25mg/dl. The most common blood group was type A for newborns. Immunohematologic tests were positive in 84% of the mothers. ABO incompatibility hemolytic disease was the fourth and second most common reasons for blood exchange transfusion in preterm and term infants, respectively. Laboratory complications were more common than clinical complications. The etiology of 48% of the alloimmunization and 42% of the hemolytic disease in these newborns was ABO incompatibility.Conclusions: Mothers with blood group O and newborns with blood group A or B with positive immunohematologic tests in first hours of life are at high risk for hemolytic disease

  20. Animal models. (United States)

    Walker, Ellen A


    As clinical studies reveal that chemotherapeutic agents may impair several different cognitive domains in humans, the development of preclinical animal models is critical to assess the degree of chemotherapy-induced learning and memory deficits and to understand the underlying neural mechanisms. In this chapter, the effects of various cancer chemotherapeutic agents in rodents on sensory processing, conditioned taste aversion, conditioned emotional response, passive avoidance, spatial learning, cued memory, discrimination learning, delayed-matching-to-sample, novel-object recognition, electrophysiological recordings and autoshaping is reviewed. It appears at first glance that the effects of the cancer chemotherapy agents in these many different models are inconsistent. However, a literature is emerging that reveals subtle or unique changes in sensory processing, acquisition, consolidation and retrieval that are dose- and time-dependent. As more studies examine cancer chemotherapeutic agents alone and in combination during repeated treatment regimens, the animal models will become more predictive tools for the assessment of these impairments and the underlying neural mechanisms. The eventual goal is to collect enough data to enable physicians to make informed choices about therapeutic regimens for their patients and discover new avenues of alternative or complementary therapies that reduce or eliminate chemotherapy-induced cognitive deficits.

    Oswalt, G C; Montes, L F; Cassady, G


    Subcutaneous fat necrosis of the newborn (SFNN) developed in a 1-week-old black boy. His mother had received numerous medications for eclampsia. Birth was by Caesarean section and complicated by meconium aspiration. There were numerous nodules over the back, buttocks and extremities that yielded a caseous-like material. Microscopically, these nodules showed crystallization and necrosis of the fat. Hypoglycemia, pneumonia, oliguria, thrombocytopenia, seizures and urinary infection were associated with the cutaneous problem and led to a fatal outcome 2 weeks after birth.

    Widianto, Arif; Nurfitri, Intan; Mahatidana, Pradipta; Abuzairi, Tomy; Poespawati, N. R.; Purnamaningsih., Retno W.


    We proposed weight monitoring system using load cell sensor for newborn incubator application. The weight sensing system consists of a load cell, conditioning signal circuit, and microcontroller Arduino Uno R3. The performance of the sensor was investigated by using the various weight from 0 up to 3000 g. Experiment results showed that this system has a small error of 4.313% and 12.5 g of threshold and resolution value. Compared to the typical baby scale available in local market, the proposed system has a lower error value and hysteresis.

    Lewis, Michelle Huckaby; Scheurer, Michael E; Green, Robert C; McGuire, Amy L


    Retention and use, without explicit parental permission, of residual dried blood samples from newborn screening has generated public controversy over concerns about violations of family privacy rights and loss of parental autonomy. The public debate about this issue has included little discussion about the destruction of a potentially valuable public resource that can be used for research that may yield improvements in public health. The research community must advocate for policies and infrastructure that promote retention of residual dried blood samples and their use in biomedical research.

    Latika Nath Sinha


    Full Text Available Background: In India, the Home Based Postnatal Newborn Care programme by Accredited Social Health Activists (ASHAs under the National Rural Health Mission was initiated in 2011 to reduce neonatal mortality rates (NMRs. ASHAs get cash incentives for six postnatal home visits for newborn care. We studied newborn care practices among mothers in Mewat, Haryana, having a high NMR and determined risk factors for unsafe practices and described the knowledge and skills of ASHAs during home visits. Methods: A cross-sectional survey was conducted among mothers who had delivered a child during the previous seven months using cluster sampling. We interviewed mothers and ASHAs in the selected subcentres using semi–structured questionnaires on the six safe newborn care practices, namely safe breastfeeding, keeping cord and eyes clean, wrapping baby, kangaroo care, delayed bathing and hand washing. Results: We interviewed 320 mothers, 61 ASHAs and observed 19 home visits. Overall, 60% of mothers adopted less than three safe practices. Wrapping newborns (96% and delayed bathing (64% were better adopted than cord care (49%, safe breastfeeding (48%, hand washing (30%, kangaroo care (20% and eye care (9%. Cultural beliefs and traditional birth attendants influenced the mother’s practices. The lack of supervision by auxiliary nurse midwives (ANM, delayed referral and transportation were the other challenges. Conclusion: Knowledge–practice gaps existed among mothers counselled by ASHAs. Poor utilization of reproductive and child health services decreased opportunities for ASHA–mother dialogue on safe practices. Recommendations included training ANMs, training TBAs as ASHAs, innovative communication strategies for ASHAs and improved referral system.

  7. L-citrulline provides a novel strategy for treating chronic pulmonary hypertension in newborn infants (United States)

    Fike, Candice D.; Summar, Marshall; Aschner, Judy L.


    Effective therapies are urgently needed for infants with forms of pulmonary hypertension that develop or persist beyond the first week of life. The L-arginine nitric oxide (NO) precursor, L-citrulline, improves NO signalling and ameliorates pulmonary hypertension in newborn animal models. In vitro studies demonstrate that manipulating L-citrulline transport alters NO production. Conclusion Strategies that increase the supply and transport of L-citrulline merit pursuit as novel approaches to managing infants with chronic, progressive pulmonary hypertension. PMID:24862864

  8. Is newborn melatonin production influenced by magnetic fields produced by incubators? (United States)

    Bellieni, Carlo Valerio; Tei, Monica; Iacoponi, Francesca; Tataranno, Maria Luisa; Negro, Simona; Proietti, Fabrizio; Longini, Mariangela; Perrone, Serafina; Buonocore, Giuseppe


    During permanence in most incubators, newborns are very close to the electric engine, which represents a source of electromagnetic fields (EMF). Previous studies demonstrated a decrease in melatonin production in adults and animals exposed to EMF. To assess melatonin production in a group of newborns exposed to EMF, and to evaluate whether removing the babies from the source of MF can affect melatonin production. We have recruited 28 babies (study group), who had spent at least 48 h in incubator where we had previously assessed the presence of significant EMF. We have measured their mean 6-hydroxy-melatonin-sulfate (6OHMS) urine excretion at the end of their permanence in the incubators, and compared it with their mean 6OHMS excretion after having been put in cribs, where EMF are below the detectable limit (babies who were not exposed to EMF during both samples. Mean 6OHMS/cr values were respectively 5.34±4.6 and 7.68±5.1ng/mg (p=0.026) when babies were exposed to EMF in incubators, and after having been put in the crib. In the control group, mean 6OHMS/cr values in the first and in the second sample were respectively 5.91±5.41 vs 6.17±3.94ng/mg (p=0.679). The transitory increase in melatonin production soon after removing newborns from incubators demonstrates a possible influence of EMF on melatonin production in newborns. Further studies are needed to confirm these data. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Rencricca, N.J.; Howard, D.; Kubanek, B.; Stohlman, F.; Department of Biological Sciences, University of Lowell, Lowell, Massachusetts, USA)


    Erythroid regeneration was studied in lethally irradiated mice given transplants containing equivalent numbers of haemopoietic stem cells (i.e. CFU) from fetal liver, neonatal marrow or adult marrow. Adult marrow was taken from normal control mice, whose CFU for the most part were not in active cell cycle, as well as from phenylhydrazine-treated groups whose CFU were in similar state of proliferation (i.e. approximately 40-50% in DNA synthesis) as those derived from fetal liver and neonatal marrow. Splenic and femoral radioiron ( 59 Fe) incorporation were measured at intervals after transplantation and were found to begin earliest in mice given fetal liver, then in animals given neonatal marrow and latest in recipients of adult marrow. Peripheral reticulocytes showed a similar pattern of recovery. The data reported herein suggest that the differences in erythroid regeneration evoked by transplants of fetal liver, neonatal marrow or adult marrow, are not solely attributed to the degree of proliferation in the pluripotential stem cell compartment. These data may, however, suggest a shorter doubling time for cells comprising the fetal and newborn committed erythroid compartments. (author)

  19. Screening of the hearing of newborns - Update

    Directory of Open Access Journals (Sweden)

    von Voß, Hubertus


    Full Text Available Introduction: Permanent congenital bilateral hearing loss (CHL of moderate or greater degree (≥40 dB HL is a rare disease, with a prevalence of about 1 to 3 per 1000 births. However, it is one of the most frequent congenital diseases. Reliance on physician observation and parental recognition has not been successful in the past in detecting significant hearing loss in the first year of life. With this strategy significant hearing losses have been detected in the second year of life. With two objective technologies based on physiologic response to sound, otoacoustic emissions (OAE and auditory brainstem response (ABR hearing screening in the first days of life is made possible. Objectives: The objective of this health technology assessment report is to update the evaluation on clinical effectiveness and cost-effectiveness of newborn hearing screening programs. Universal newborn hearing screening (UHNS (i, selective screening of high risk newborns (ii, and the absence of a systematic screening program are compared for age at identification and age at hearing aid fitting of children with hearing loss. Secondly the potential benefits of early intervention are analysed. Costs and cost-effectiveness of newborn hearing screening programs are determined. This report is intended to make a contribution to the decision making whether and under which conditions a newborn hearing screening program should be reimbursed by the statutory sickness funds in Germany. Methods: This health technology assessment report updates a former health technology assessment (Kunze et al. 2004 [1]. A systematic review of the literature was conducted, based on a documented search and selection of the literature using predefined inclusion and exclusion criteria and a documented extraction and appraisal of the included studies. To assess the cost-effectiveness of the different screening strategies in Germany the decision analytic Markov state model which had been developed in

  20. The effects of alcohol in newborns

    Directory of Open Access Journals (Sweden)

    Maria dos Anjos Mesquita


    Full Text Available The purpose of this article was to present a review of the effects of alcohol consumption by pregnant mothers on their newborn. Definitions, prevalence, pathophysiology, clinical features, diagnostic criteria, follow-up, treatment and prevention were discussed. A search was performed in Medline, LILACS, and SciELO databases using the following terms: “fetus”, “newborn”, “pregnant woman”, “alcohol”, “alcoholism”, “fetal alcohol syndrome”, and “alcohol-related disorders”. Portuguese and English articles published from 2000 to 2009 were reviewed. The effects of alcohol consumed by pregnant women on newborns are extremely serious and occur frequently; it is a major issue in Public Health worldwide. Fetal alcohol spectrum disorders cause harm to individuals, their families, and the entire society. Nevertheless, diagnostic difficulties and inexperience of healthcare professionals result in such damage, being remembered rarely or even remaining uncovered. Alcohol-related injury to the fetus is fully avoidable; all it takes is for women not to drink alcoholic beverages during pregnancy. Therefore, detecting women who consume alcohol during pregnancy is paramount, as are specific programs to educate people about the consequences of alcohol use during pregnancy and breastfeeding.

  1. Late haemorrhagic disease of the newborn. (United States)

    Zengin, Emine; Sarper, Nazan; Türker, Gülcan; Corapçioğlu, Funda; Etuş, Volkan


    Late haemorrhagic disease of the newborn (HDN) can occur owing to a lack of vitamin K prophylaxis, as a manifestation of an underlying disorder or idiopatically from the 8th day to 12 weeks after birth. Eight infants admitted to Kocaeli University Hospital with nine episodes of late HDN between January 2002 and April 2005 were evaluated retrospectively from hospital records. The median age at presentation was 46 (26-111) days. All the infants were born at full-term to healthy mothers and were exclusively breast-fed. All had an uneventful perinatal history, except one who had meconium aspiration. Four patients had received no vitamin K prophylaxis and another three had uncertain histories. At presentation, six had intracranial bleeding and the remainder had bleeding either from the venepuncture site or the gastro-intestinal tract. The presenting signs and symptoms were irritability, vomiting, bulging or full fontanelle, convulsions and diminished or absent neonatal reflexes. Galactosaemia was detected in a 2-month-old infant with prolonged jaundice. There was no surgery-related mortality or complications but one survived for only 2 days on ventilatory support following surgery. Only one of the six survivors had severe neurological sequelae. Late HDN frequently presents with intracranial haemorrhage, leading to high morbidity and mortality. HDN can be the manifestation of an underlying metabolic disorder. Vitamin K prophylaxis of the newborn should be routine in developing countries.

    Юрій Анатолійович Коломійченко


    Full Text Available Aim of the work. To analyze indices of the different radiological methods and to compare it.Materials and methods. The newborns with spinal trauma (n=33 were analyzed, the children who have been excluded this diagnosis (n=27 formed the control group. All children underwent the radiography of cervical spine, the part of them – MRT and USG. There was carried out the visual assessment and analysis of metrical indices.Results. Patients were separated into groups of heaviness, 16 patients with slight degree, 10 with middle one and 7 with heavy degree of injury. At all methods the width of the Cruveilhier joint fissure in children with an injury of upper cervical spine reliably (р<0,001 differs from the one in the control group, and was detected the moderate correlation (r>0,4.When using radiology and MRT in children with traumatic injures the width of prevertebral soft tissues was reliably more and the degree of reliability was higher at radiology (р<0,001, than at MRT (р<0,01. The correlations between the width of soft tissues and the degree of heaviness were detected at all levels at radiography and only at the level C1 at MRT.Conclusions. An analysis demonstrated the different degree of importance of some indices for detecting injuries of the upper cervical spine in newborns. There was also proved that the metrical data of the different methods not reliably differ

  3. Surfactant secretion and clearance in the newborn

    International Nuclear Information System (INIS)

    Stevens, P.A.; Wright, J.R.; Clements, J.A.


    Pregnant rabbits (30 days) were injected intravenously with [3H]choline 8 h before delivery. The fetuses were delivered, and lung lavage and lamellar body phospholipids (PL) were analyzed. Some newborns also received radioactively labeled surfactant intratracheally on delivery and were permitted to breathe. With time, intratracheal label decreased in lavage and appeared in the lamellar body fraction, and intravenous label accumulated in both pools. Using a tracer analysis for non-steady state, we calculated surfactant secretion and clearance rates for the newborn period. Before birth, both rates rose slightly from 1.8 micrograms PL.g body wt-1.h-1 at 6 h before birth to 7.3 at birth. Immediately after birth, secretion rate rose to 37.7 micrograms PL.g body wt-1.h-1. Between 1.5 and 2 h after birth it fell to a minimum of 1.8 micrograms PL.g body wt-1.h-1 and then rose slowly to 6.0 at 12 h. After birth, clearance rate increased less than secretion rate (maximum 24.7 micrograms PL.g body wt-1.h-1 shortly after birth) then followed the same pattern but did not balance secretion rate in the 1st day

  4. Congenital abnormalities in newborns of consanguineous and nonconsanguineous parents. (United States)

    Naderi, S


    The aim of this study was to determine the types, patterns, and frequencies of congenital anomalies among newborns of both consanguineous and nonconsanguineous parents in southern Iran. From 9526 consecutive pregnancies observed, 9623 newborns resulted (9431 singleton and 95 sets of multiple gestation). There were 7261 newborns from nonconsanguineous parents and 2362 (24.5%) babies from consanguineous marriages. Of the total pregnancies, 1.54% resulted in malformed children (1.53% of singleton and 2.1% of multiple gestations). The incidence of congenital abnormalities in newborns of nonconsanguineous parents was 1.66% as compared to 4.02% for newborns of the consanguineous group. Major and multiple malformations were found to be slightly more common in the consanguinous group. Prematurity, prenatal mortality rate, and congenital abnormalities were more common in the consanguineous group. Probably the closer the familial relationship of the parents, the greater the chances of congenital abnormalities.

  6. Delivery factors for brachial plexus palsy by newborns

    Directory of Open Access Journals (Sweden)

    D. Balić


    Full Text Available Brachial plexus injuries represent a low percentage of delivery complications. Most newborns fully recover from the injury, very few retain a permanent neurological deficit whereas some remain unnoticed. An objective of this study was to establish delivery factors for brachial plexus palsy at the Clinic for Gynecology and Obstetrics and relation between the deficits with length of delivery, the length of delivery periods, induction of delivery and surgical interventions at delivery. The analysed group involved 90 newborn babies with an injury of brachial plexus made at the delivery in the period between 01.01.1996 and 31.12.2005. The controlled group included 90 newborns randomly selected. The comparison was made using an χ2 test. The incidence of injuries of plexus brachialis was 1.72 per 1,000 newborns. Analysing the length of delivery there was no difference found between the analysed and controlled group (p > 0.05. In the group of newborns with the injury of brachial plexus it was found that the second delivery period was significantly shorter (p < 0.01. In the analysed group 89 (98.8% newborn babies were delivered vaginally and one (1.2% was delivered by the cesarean section. 13 newborns (14.4% from the analysed group were delivered with application of vacuum extractor and in the controlled group it was the case with one (1.2% newborn baby (p < 0.01. The delivery of 98.8% newborns from the analysed group started spontaneously and two deliveries (1.2% were induced. Risk factors for injuries of plexus brachialis in newborns at the Clinic for Gynaecology and Obstetrics of the University Clinical Centre Tuzla include shortened second delivery period and completion of deliveries applying the vacuum extractor.

  7. Animal welfare: an animal science approach. (United States)

    Koknaroglu, H; Akunal, T


    Increasing world population and demand for animal-derived protein puts pressure on animal production to meet this demand. For this purpose animal breeding efforts were conducted to obtain the maximum yield that the genetic makeup of the animals permits. Under the influence of economics which is the driving force behind animal production, animal farming became more concentrated and controlled which resulted in rearing animals under confinement. Since more attention was given on economics and yield per animal, animal welfare and behavior were neglected. Animal welfare which can be defined as providing environmental conditions in which animals can display all their natural behaviors in nature started gaining importance in recent years. This does not necessarily mean that animals provided with good management practices would have better welfare conditions as some animals may be distressed even though they are in good environmental conditions. Consumers are willing to pay more for welfare-friendly products (e.g.: free range vs caged egg) and this will change the animal production practices in the future. Thus animal scientists will have to adapt themselves for the changing animal welfare rules and regulations that differ for farm animal species and countries. In this review paper, animal welfare is discussed from an animal science standpoint. Crown Copyright © 2013. Published by Elsevier Ltd. All rights reserved.

    To study the relationship of leptin quantity of placenta, amniotic fluid, umbilical blood, maternal blood and newborn's weight, leptin levels of placenta, amniotic fluid, umbilical blood and maternal blood of 59 pregnant women were detected by RIA. Results were: (1) leptin was be detected from placenta, amniotic fluid, umbilical blood and maternal blood; (2) there was an obvious difference between leptin quantities of placenta, amniotic fluid, umbilical blood and maternal blood (P < 0.01); (3) there was an obvious difference between leptin quantities of placenta, amniotic fluid, umbilical blood and maternal blood for normal pregnant women and pregnancy induced hypertension (P < 0.01); (4) there was an obvious difference between leptin quantities of maternal blood and placenta (P < 0.01). It may be of important significance to detect eh leptin quantity of amniotic fluid and maternal blood in pregnant women for predicting the weight and growth of newborns and treat pregnancy induced hypertension

  10. The host defense peptide beta-defensin 1 confers protection against Bordetella pertussis in newborn piglets. (United States)

    Elahi, Shokrollah; Buchanan, Rachelle M; Attah-Poku, Sam; Townsend, Hugh G G; Babiuk, Lorne A; Gerdts, Volker


    Innate immunity plays an important role in protection against respiratory infections in humans and animals. Host defense peptides such as beta-defensins represent major components of innate immunity. We recently developed a novel porcine model of pertussis, an important respiratory disease of young children and infants worldwide. Here, we investigated the role of porcine beta-defensin 1 (pBD-1), a porcine defensin homologue of human beta-defensin 2, in conferring protection against respiratory infection with Bordetella pertussis. In this model, newborn piglets were fully susceptible to infection and developed severe bronchopneumonia. In contrast, piglets older than 4 weeks of age were protected against infection with B. pertussis. Protection was associated with the expression of pBD-1 in the upper respiratory tract. In fact, pBD-1 expression was developmentally regulated, and the absence of pBD-1 was thought to contribute to the increased susceptibility of newborn piglets to infection with B. pertussis. Bronchoalveolar lavage specimens collected from older animals as well as chemically synthesized pBD-1 displayed strong antimicrobial activity against B. pertussis in vitro. Furthermore, in vivo treatment of newborn piglets with only 500 mug pBD-1 at the time of challenge conferred protection against infection with B. pertussis. Interestingly, pBD-1 displayed no bactericidal activity in vitro against Bordetella bronchiseptica, a closely related natural pathogen of pigs. Our results demonstrate that host defense peptides play an important role in protection against pertussis and are essential in modulating innate immune responses against respiratory infections.

  11. Relations of Nosological Factors and Energy Expenditure in Newborns

    Directory of Open Access Journals (Sweden)

    A. N. Shmakov


    Full Text Available Purpose. With the aid of indirect calorimetry, to evaluate whether the nosological factors affect energy exchange in severely ill newborns.Materials and methods. Indirect calorimetry was employed to determine the true energy expenditure in new borns under the mechanical ventilation because of intranatal postanoxia encephalopathy (n=19, severe sepsis (n=18, and urgent surgery (n=19. Energy expenditure at rest was estimated at the beginning of intensive therapy and in in 48 hours. Sedation in groups was similar.Results. At the first stage, the energy exchange in all newborns was characterized by hypometabolism. In cases of damage of the central nervous system the anaerobic metabolism was increased, and the principal used substrate was glucose; the most prolonged hypometabolism was revealed in newborns with sepsis, in which the utilization of lactate was decreased, and the main energetic substrate were lipids; in early postoperative period, the decrease in energy expenditure was not associated with preferential oxidation of glucose or lipids, and disappeared due to elimination of anesthetics.Conclusion. Energetic hypometabolism can be considered as a main reaction of the newborn organism to previous invasion. Acute posthypoxic brain damage in newborns is characterized by high activity of peroxidation associated with hypometabolism. For newborns with severe sepsis a slow recovery of aerobic metabolism and intensity of energy expenditure were evident. Early postoperative period in newborns was characterized by profound iatrogenic hypometabolism with fast normalization of energy expenditure.

  12. Managing hypertension in the newborn infants

    Directory of Open Access Journals (Sweden)

    Azar Nickavar


    Full Text Available Hypertension in newborn infants, particularly those requiring intensive care, is becoming increasingly recognized, with prevalence of 0.2-3%. Recent studies have established normative tables for blood pressure (BP in both term and pre-term infants based on the gestational age, postnatal age, gender, weight and height, identifying the neonates at increased risk for early-onset cardiovascular disease. Common causes of neonatal hypertension include thromboembolic complications secondary to umbilical artery catheterization, congenital renal structural malformation, renovascular disease, aortic coarctation, as well as acute kidney injury and certain medications. A careful diagnostic evaluation should lead to identification of the underlying cause of hypertension in most infants. Treatment options should be tailored to the severity; and underlying cause of hypertension, including intravenous and/or oral therapy. This review summarizes recent work in these areas, focusing on optimal BP measurement, definition, evaluation and management of hypertension as well as advances in drug therapy of neonatal hypertension.

  13. Persistent pulmonary hypertension of the newborn. (United States)

    Nair, P M C; Bataclan, Maria Flordeliz A


    This article attempts to define a complicated, yet not rare disease of the neonate, which presents with extreme hypoxemia due to increased pulmonary vascular resistance, resulting in diversion of the pulmonary venous blood through persistent fetal channels, namely ductus arteriosus and foramen ovale. Pathophysiology, diagnostic approach and the various modalities of management are analyzed. Persistent pulmonary hypertension of the newborn is multi-factorial, which is reflected in the management as well. These babies are extremely labile to hypoxia and should be stabilized with minimum handling. One hundred percent oxygen and ventilation are the mainstay of treatment. The role of hyperventilation, alkalinization, various non-specific vasodilators such as tolazoline, magnesium sulphate, selective vasodilators such as inhaled nitric oxide, adenosine and the role of high frequency oscillatory ventilation and extra corporeal membrane oxygenation are discussed. With the newer modalities of management, the outlook has improved with mortality of less than 20% and fewer long-term deficits.

  14. Jaundice in the full-term newborn. (United States)

    Cohen, Shannon Munro


    Jaundice is a common problem affecting over half of all full-term and most preterm infants. Jaundice describes the yellow orange hue of the skin caused by excessive circulating levels of bilirubin that accumulate in the skin. In most healthy full-term newborns, jaundice is noticed during the first week of life. Shortened hospital stays and inconsistent follow up, especially for first-time breastfeeding mothers, prompted the American Academy of Pediatrics (AAP) to update management guidelines. Health care providers need to be familiar with the diagnosis and management of jaundice to prevent brain, vision, and hearing damage. Treatment of choice for jaundice remains close observation and frequent feeding followed by phototherapy, and finally exchange transfusion for severe or refractory cases.

  15. Management of severe hypertension in the newborn. (United States)

    Dionne, Janis M; Flynn, Joseph T


    Blood pressure is considered a vital sign, as values too low or too high can be related with serious morbidity and mortality. In neonates, normal blood pressure values undergo rapid changes, especially in premature infants, making the recognition of abnormal blood pressures more challenging. Severe hypertension can occur in neonates and infants and is a medical emergency, often manifesting with congestive heart failure or other life-threatening complications. The cause or risk factors for the hypertension can usually be identified and may guide management. Most classes of antihypertensive medications have been used in the neonatal population. For severe hypertension, intravenous short-acting medications are preferred for a controlled reduction of blood pressure. In this article, we focus on identification, aetiology and management of severe hypertension in the newborn. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  16. Newborn exoplanet eyed for moons and rings (United States)

    Clery, Daniel


    Astronomers are staring at a nearby star in hopes of seeing a giant baby of a planet—perhaps accompanied by dust clouds, rings, or newborn moons—pass across its face. Last week, the newest and tiniest telescope joined the vigil, when the French-built PicSat rode into orbit on an Indian rocket. It will be able to continuously monitor the star, β Pictoris, until chances of seeing the once-in-20-year transit event diminish in a few months' time. Astronomers are fascinated by β Pictoris, a bright star just 63 light-years away, because it is a natural laboratory for how solar systems form given its age of only 24 million years—an infant in stellar terms.

  17. Intracranial hemorrhage of the mature newborn infant

    International Nuclear Information System (INIS)

    Takemine, Hisao


    Concerning four mature newborn infants with intracranial hemorrhage diagnosed by CT, the labour course, treatment, and prognoses were discussed. Of intracranial hemorrhage, 70.7% was small hemorrhage along the cerebellar tentorium and the falx cerebri, 12.2% subdural hemorrhage in the posterior cranial fossa, and 9.8% subdural hemorrhage in the fornex. Intraventricular or extradural hemorrhage was rarely found. The prognosis is determined by severeness of neurotic symptoms due to cerebral hypoxia. Subdural hemorrhage of the posterior cranial fossa resulted in cerebral palsy in one fifth of the cases, and in slight enlargement of the ventricle in three fifths. Subdural hematoma left porencephaly in one fourth of the patients, but the remaining recovered to normal. (Ueda, J.)

    Full Text Available Development of temperature regulation was investigated by determining the ability of newborn reindeer calves (Rangifer tarandus tarandus to maintain a normal body temperature when exposed to an incrementially decreasing ambient temperature. Newborn calves (1 day old can maintain their body temperature even at -15 °C. They can increase their metabolic rate five- to sixfold. Heat production is primarily stimulated by the sympathetic nervous system. The response to exogenous administration of noradrenaline and propranolol was investigated.Poronvasan låmmonsååtelyn syntymånjålkeinen kehittyminen.Abstract in Finnish / Yhteenveto: Vastasyntyneiden poronvasojen kylmansietoa ja lammonsaatelya tutkittiin toukokuussa 1981 Inarin Kaamasessa Paliskuntain yhdistyksen koetarhassa.

  20. Large number discrimination in newborn fish.

    Directory of Open Access Journals (Sweden)

    Laura Piffer

    Full Text Available Quantitative abilities have been reported in a wide range of species, including fish. Recent studies have shown that adult guppies (Poecilia reticulata can spontaneously select the larger number of conspecifics. In particular the evidence collected in literature suggest the existence of two distinct systems of number representation: a precise system up to 4 units, and an approximate system for larger numbers. Spontaneous numerical abilities, however, seem to be limited to 4 units at birth and it is currently unclear whether or not the large number system is absent during the first days of life. In the present study, we investigated whether newborn guppies can be trained to discriminate between large quantities. Subjects were required to discriminate between groups of dots with a 0.50 ratio (e.g., 7 vs. 14 in order to obtain a food reward. To dissociate the roles of number and continuous quantities that co-vary with numerical information (such as cumulative surface area, space and density, three different experiments were set up: in Exp. 1 number and continuous quantities were simultaneously available. In Exp. 2 we controlled for continuous quantities and only numerical information was available; in Exp. 3 numerical information was made irrelevant and only continuous quantities were available. Subjects successfully solved the tasks in Exp. 1 and 2, providing the first evidence of large number discrimination in newborn fish. No discrimination was found in experiment 3, meaning that number acuity is better than spatial acuity. A comparison with the onset of numerical abilities observed in shoal-choice tests suggests that training procedures can promote the development of numerical abilities in guppies.

  1. Prenatal ethanol exposure alters steroidogenic enzyme activity in newborn rat testes. (United States)

    Kelce, W R; Rudeen, P K; Ganjam, V K


    We have examined the in utero effects of ethanol exposure on testicular steroidogenesis in newborn male pups. Pregnant Sprague-Dawley rats were fed a liquid ethanol diet (35% ethanol-derived calories), a pair-fed isocaloric liquid diet, or a standard laboratory rat chow and water diet beginning on Day 12 of gestation and continuing through parturition. Although there were no significant differences in the enzymatic activity of 5-ene-3 beta-hydroxysteroid dehydrogenase/isomerase or C17,20-lyase, the enzymatic activity of 17 alpha-hydroxylase was significantly (p less than 0.01) reduced (i.e., approximately 36%) in the ethanol-exposed pups compared to those from the pair-fed and chow treatment groups. This lesion in testicular steroidogenic enzyme activity in newborn male pups exposed to alcohol in utero was transient as 17 alpha-hydroxylase activity from the ethanol-exposed animals returned to control levels by postnatal Day 20 and remained at control levels through adulthood (postnatal Day 60). These data suggest that the suppression of the perinatal testosterone surge in male rats exposed to alcohol in utero and the associated long term demasculinizing effects of prenatal ethanol exposure might be the result of reduced testicular steroidogenic enzyme activity in the perinatal animal.

    Dursun F, Gerenli N, Kırmızıbekmez H. Cholestasis and hypercalcemia secondary to panhypopituitarism in a newborn. Turk J Pediatr 2017; 59: 100-103. Cholestatic hepatitis and hypercalcemia are rare features of hypopituitarism in newborns. So diagnosis of hypopituitarism is frequently delayed. The most frequent symptoms of congenital hypopituitarism are hypoglycemia, prolonged jaundince and micropenis. A patient with congenital hypopituitarism associated with cholestasis and hypercalcemia is reported here. Newborns with hypercalcemia and cholestasis should alert pediatricians to the possibility of congenital hypopituitarism and prompt endocrinological investigation.

The authors state that the early diagnosis of the risk factors is an important step in the prevention of ateromatous plaques. Some people are now in the investigation of the normal levels of cholesterol and triglicerides in the blood of the umbilical cord. This values seems similar in different places all over the world and have served to establish the possible interrelation between the newborn hiperlipidemia and the coronary risk.

  2. Antibacterial-induced nephrotoxicity in the newborn. (United States)

    Fanos, V; Cataldi, L


    Antibacterials are the primary cause of drug-induced kidney disease in all age groups and these agents bring about renal damage by 2 main mechanisms, namely, direct and immunologically mediated. For some antibacterials (aminoglycosides and vancomycin) nephrotoxicity is very frequent but generally reversible upon discontinuation of the drug. However, the development of acute renal failure with these agents is possible and its incidence in the newborn seems to be increasing. Antibacterials are very often used in the neonatal period especially in very low birthweight neonates. The role of neonatal age in developing nephrotoxicity has still to be defined. Since the traditional laboratory parameters of nephrotoxicity are abnormal only in the presence of substantial renal damage, the identification of early non-invasive markers of the renal damage (urinary microglobulins, enzymes and growth factors) is of importance. Aminoglycosides and glycopeptides are still frequently used, either alone or in combination, despite their low therapeutic index. Numerous factors intervene in bringing about the kidney damage induced by these 2 classes of antibacterials, such as factors related to the antibacterial itself and others related to the associated pathology as well as pharmacological factors. Nephrotoxicity can be caused by the beta-lactams and related compounds. Their potential to cause nephrotoxicity decreases in the order: carbapenems > cephalosporins > penicillins > monobactams. Third generation cephalosporins are frequently used in neonates. However, they are well tolerated compounds at the renal level. The nephrotoxicity of other classes of antibacterials is not discussed either because they are only used in neonates in exceptional circumstances, for example, chloramphenicol and cotrimoxazole (trimethoprim-sulfamethoxazole) or are not associated with significant nephrotoxicity, for example macrolides, clindamicin, quinolones, rifampicin (rifampin) and metronidazole

  3. Enhanced learning of natural visual sequences in newborn chicks. (United States)

    Wood, Justin N; Prasad, Aditya; Goldman, Jason G; Wood, Samantha M W


    To what extent are newborn brains designed to operate over natural visual input? To address this question, we used a high-throughput controlled-rearing method to examine whether newborn chicks (Gallus gallus) show enhanced learning of natural visual sequences at the onset of vision. We took the same set of images and grouped them into either natural sequences (i.e., sequences showing different viewpoints of the same real-world object) or unnatural sequences (i.e., sequences showing different images of different real-world objects). When raised in virtual worlds containing natural sequences, newborn chicks developed the ability to recognize familiar images of objects. Conversely, when raised in virtual worlds containing unnatural sequences, newborn chicks' object recognition abilities were severely impaired. In fact, the majority of the chicks raised with the unnatural sequences failed to recognize familiar images of objects despite acquiring over 100 h of visual experience with those images. Thus, newborn chicks show enhanced learning of natural visual sequences at the onset of vision. These results indicate that newborn brains are designed to operate over natural visual input.

    Sobel, Howard L; Silvestre, Maria Asuncion A; Mantaring, Jacinto Blas V; Oliveros, Yolanda E; Nyunt-U, Soe


    Aim A deadly nosocomial outbreak in a Philippine hospital drew nationwide attention to neonatal sepsis. Together with specific infection control measures, interventions that protect newborns against infection-related mortality include drying, skin-to-skin contact, delayed cord clamping, breastfeeding initiation and delayed bathing. This evaluation characterized hospital care in the first hours of life with the intent to drive policy change, strategic planning and hospital reform. Methods Trained physicians observed 481 consecutive deliveries in 51 hospitals using a standardized tool to record practices and timing of immediate newborn care procedures. Results Drying, weighing, eye care and vitamin K injections were performed in more than 90% of newborns. Only 9.6% were allowed skin-to-skin contact. Interventions were inappropriately sequenced, e.g. immediate cord clamping (median 12 sec), delayed drying (96.5%) and early bathing (90.0%). While 68.2% were put to the breast, they were separated two minutes later. Unnecessary suctioning was performed in 94.9%. Doctors trained in neonatal resuscitation were 2.5 (1.1–5.7) times more likely to unnecessarily suction vigorous newborns. Two per cent died and 5.7% developed sepsis/pneumonia. Conclusions This minute-by-minute observational assessment revealed that performance and timing of immediate newborn care interventions are below WHO standards and deprive newborns of basic protections against infection and death.

  5. Hypothermia therapy for newborns with hypoxic ischemic encephalopathy. (United States)

    Silveira, Rita C; Procianoy, Renato S


    Therapeutic hypothermia reduces cerebral injury and improves the neurological outcome secondary to hypoxic ischemic encephalopathy in newborns. It has been indicated for asphyxiated full-term or near-term newborn infants with clinical signs of hypoxic-ischemic encephalopathy (HIE). A search was performed for articles on therapeutic hypothermia in newborns with perinatal asphyxia in PubMed; the authors chose those considered most significant. There are two therapeutic hypothermia methods: selective head cooling and total body cooling. The target body temperature is 34.5 °C for selective head cooling and 33.5 °C for total body cooling. Temperatures lower than 32 °C are less neuroprotective, and temperatures below 30 °C are very dangerous, with severe complications. Therapeutic hypothermia must start within the first 6h after birth, as studies have shown that this represents the therapeutic window for the hypoxic-ischemic event. Therapy must be maintained for 72 h, with very strict control of the newborn's body temperature. It has been shown that therapeutic hypothermia is effective in reducing neurologic impairment, especially in full-term or near-term newborns with moderate hypoxic-ischemic encephalopathy. Therapeutic hypothermia is a neuroprotective technique indicated for newborn infants with perinatal asphyxia and hypoxic-ischemic encephalopathy. Copyright © 2015 Sociedade Brasileira de Pediatria.

  6. Inborn Errors of Intermediary Metabolism in Critically Ill Mexican Newborns

    Directory of Open Access Journals (Sweden)

    Ibarra-González Isabel MSc


    Full Text Available Inborn errors of intermediary metabolism (IEiM are complex diseases with high clinical heterogeneity, and some patients who have severe enzyme deficiencies or are subjected to stress (catabolism/infections actually decompensate in the neonatal period. In this study, we performed metabolic tests on 2025 newborns in Mexico admitted to 35 neonatal intensive care units or emergency wards (NICUs/EWs over a 6-year period, in whom a metabolic disorder was clinically suspected. Of these 2025 newborns with sickness, 11 had IEiM, revealing a prevalence of 1:184. Clinical characteristics and outcomes of the newborns with confirmed IEiM are shown. Of these 11 patients, 4 had isolated methylmalonic acidemia, 3 had maple syrup urine disease, 2 had urea cycle disorders, 1 had 3-hydroxy-3-methylglutaric acidemia, and 1 had isovaleric acidemia. During the first week of life (average 3 days, all of these newborns presented with impaired alertness, hypotonia, feeding difficulties, and vomiting along with metabolic acidosis and hyperammonemia. Of the 11 newborns with IEiM, 7 died, leading to a mortality rate of 64%. In conclusion, the differential diagnosis of newborns admitted to the NICU/EW must include IEiM, requiring systematic screening of this population.

  7. In utero exposure to dioxins and dioxin-like compounds and anogenital distance in newborns and infants. (United States)

    Vafeiadi, Marina; Agramunt, Silvia; Papadopoulou, Eleni; Besselink, Harrie; Mathianaki, Kleopatra; Karakosta, Polyxeni; Spanaki, Ariana; Koutis, Antonis; Chatzi, Leda; Vrijheid, Martine; Kogevinas, Manolis


    Anogenital distance in animals is used as a measure of fetal androgen action. Prenatal exposure to dioxins and dioxin-like compounds in rodents causes reproductive changes in male offspring and decreases anogenital distance. We assessed whether in utero exposure to dioxins and dioxin-like compounds adversely influences anogenital distance in newborns and young children (median age, 16 months; range, 1-31 months). We measured anogenital distance among participants of the "Rhea" mother-child cohort study in Crete and the Hospital del Mar (HMAR) cohort in Barcelona. Anogenital distance (AGD; anus to upper penis), anoscrotal distance (ASD; anus to scrotum), and penis width (PW) were measured in 119 newborn and 239 young boys; anoclitoral (ACD; anus to clitoris) and anofourchetal distance (AFD; anus to fourchette) were measured in 118 newborn and 223 young girls. We estimated plasma dioxin-like activity in maternal blood samples collected at delivery with the Dioxin-Responsive Chemically Activated LUciferase eXpression (DR CALUX®) bioassay. Anogenital distances were sexually dimorphic, being longer in males than females. Plasma dioxin-like activity was negatively associated with AGD in male newborns. The estimated change in AGD per 10 pg CALUX®-toxic equivalent/g lipid increase was -0.44 mm (95% CI: -0.80, -0.08) after adjusting for confounders. Negative but smaller and nonsignificant associations were observed for AGD in young boys. No associations were found in girls. Male infants may be susceptible to endocrine-disrupting effects of dioxins. Our findings are consistent with the experimental animal evidence used by the Food and Agriculture Organization/World Health Organization to set recommendations for human dioxin intake.

  8. State of newborn health in India. (United States)

    Sankar, M J; Neogi, S B; Sharma, J; Chauhan, M; Srivastava, R; Prabhakar, P K; Khera, A; Kumar, R; Zodpey, S; Paul, V K


    About 0.75 million neonates die every year in India, the highest for any country in the world. The neonatal mortality rate (NMR) declined from 52 per 1000 live births in 1990 to 28 per 1000 live births in 2013, but the rate of decline has been slow and lags behind that of infant and under-five child mortality rates. The slower decline has led to increasing contribution of neonatal mortality to infant and under-five mortality. Among neonatal deaths, the rate of decline in early neonatal mortality rate (ENMR) is much lower than that of late NMR. The high level and slow decline in early NMR are also reflected in a high and stagnant perinatal mortality rate. The rate of decline in NMR, and to an extent ENMR, has accelerated with the introduction of National Rural Health Mission in mid-2005. Almost all states have witnessed this phenomenon, but there is still a huge disparity in NMR between and even within the states. The disparity is further compounded by rural-urban, poor-rich and gender differentials. There is an interplay of different demographic, educational, socioeconomic, biological and care-seeking factors, which are responsible for the differentials and the high burden of neonatal mortality. Addressing inequity in India is an important cross-cutting action that will reduce newborn mortality.

  9. Radio transients from newborn black holes (United States)

    Kashiyama, Kazumi; Hotokezaka, Kenta; Murase, Kohta


    We consider radio emission from a newborn black hole (BH), which is accompanied by a mini-disk with a mass of ≲ M⊙. Such a disk can be formed from an outer edge of the progenitor's envelope, especially for metal-poor massive stars and/or massive stars in close binaries. The disk accretion rate is typically super-Eddington and an ultrafast outflow with a velocity of ˜0.1-0.3 c will be launched into the circumstellar medium. The outflow forms a collisionless shock, and electrons are accelerated and emit synchrotron emission in radio bands with a flux of ˜ 10^{26-30} erg s^{-1} Hz^{-1} days to decades after the BH formation. The model predicts not only a fast UV/optical transient but also quasi-simultaneous inverse-Compton X-ray emission ˜ a few days after the BH formation, and the discovery of the radio counterpart with coordinated searches will enable us to identify this type of transients. The occurrence rate can be 0.1 - 10 % of the core-collapse supernova rate, which makes them a promising target of dedicated radio observations such as the Jansky VLA Sky Survey.

  10. Echocardiographic Diagnostics of Myocardial Infarction in Newborns

    Directory of Open Access Journals (Sweden)

    G. V. Revunenkov


    Full Text Available Early and correct diagnostics of myocardial infarction in newborns is impossible without modern instrumental methods, among which echocardiography is the leading one. Hypokinesia, akinesia or dyskinesia of local segments of the heart ventricular wall is determined with echocardiography. We examined a 3-days-old baby with circulatory failure requiring cardiotonic support. On auscultation there was a heart murmur. It was an intracardiac conduction disoder and infarction-like changes on ECG, however, a convincing evidence to interpret the patient’s condition as myocardial infarction has not been received. Therefore, it was decided to conduct echocardiography. According to the results of echocardiography the presence of hyperechogenic diskinetic locus in the apical segment of the right ventricle (post-infarction scar, a local pericardial effusion in the same projection, hyperechogenic movable mass (thrombus in the apical segment of the right ventricle were determined that together with the results of the ECG allowed us to set diagnosis myocardial infarction. Transthoracic echocardiography is one of highly informative methods; the data obtained allowed to correctly interpret the clinical picture of heart failure and to reveal the cause of the patien’st dependance on cardiotonic support.

  11. Health Literacy Among Parents of Newborn Infants (United States)

    Mackley, Amy; Winter, Michael; Guillen, Ursula; Paul, David A.; Locke, Robert


    BACKGROUND Health Literacy is the ability to obtain, process, and understand health information to make knowledgeable health decisions. PURPOSE To determine baseline health literacy of NICU parents at a tertiary care hospital during periods of crucial information exchange. METHODS Health Literacy of English speaking NICU parents was assessed using the Newest vital Sign (NVS) on admission (n=121) and discharge (n=59). A quasi-control group of well newborn (WBN) parents (n=24) and prenatal obstetric clinic (PRE) parents (n=18) were included. A single, Likert-style question measured nurse’s assessment of parental comprehension with discharge teaching. Suspected limited health literacy (SLHL) was defined as NVS score of ≤3. FINDINGS / RESULTS Forty-three percent of parents on NICU admission and 32% at NICU discharge had SLHL (pNICU parents and 25% of WBN parents with SLHL at time of admission/infant birth had a college education. Nurse subjective measurement of parental comprehension of discharge instructions was not correlated to the objective measurement of health literacy (p=0.26). IMPLICATIONS FOR PRACTICE SLHL is common during peak time periods of complex health discussion in the NICU, WBN, and PRE settings. NICU providers may not accurately gauge parent’s literacy status. IMPLICATIONS FOR RESEARCH Methods for improving health communication are needed. Studies should evaluate SLHL in a larger NICU population and across different languages and cultures. PMID:27391562

  12. Sonographic templates of newborn perforator stroke. (United States)

    Abels, Lyanne; Lequin, Maarten; Govaert, Paul


    Many paediatric strokes occur in the perinatal period. Improvement in neuroimaging has increased detection in newborns with neurological symptoms. To define sonographic templates of neonatal stroke in the territory of perforators of the anterior choroidal artery (AChA) and the anterior (ACA), middle (MCA) and posterior (PCA) cerebral arteries. In 24 neonates with perforator stroke, we retrospectively studied antenatal and perinatal events. Brain sonography was performed with an 8.5-MHz probe. Only hyperechoic lesions in the thalamus and/or striatum and/or centrum semiovale were included. MRI was obtained using a 1.5-T machine. We detected 28 perforator strokes in 24 infants (6 preterm): 5 MCA medial striate, 8 MCA lateral striate, 3 MCA centrum semiovale, 4 ACA Heubner's, 5 PCA thalamic arteries, 1 AChA, and 2 hypothalamic perforators. We attributed clinical seizures to stroke in two infants only. Catheter-related embolism (certain in three, possible in six others) and birth trauma (two) were probable causes. Specific conditions were found in six others. Only one infant (in nine evaluated) had an increased prothrombotic risk (fII mutation). In describing the lesions, we focused on the templates of infarction as seen in a parasagittal US sweep. Infarcts were confirmed by MRI in 21 patients. Our study showed that infarct topography can be evaluated reliably with brain sonography. This is important given the asymptomatic character of most lesions.

  13. Newborn bloodspot screening policy framework for Australia

    Directory of Open Access Journals (Sweden)

    Peter O'Leary


    Full Text Available Background The aim of newborn bloodspot screening (NBS is to identify rare genetic and non-genetic conditions in children soon after birth in order to commence therapies that prevent the development of progressive, serious, and irreversible disabilities. Universal NBS programmes have been implemented in most countries, with minor adaptations to target conditions most relevant to the local healthcare environment. Aims In this article, we describe the initiatives of international and Australian governments to develop policies to address the expansion of NBS in their healthcare systems. Methods We have reviewed published public policies and literature to formulate recommendations based on clinical, social, legal, and ethical principles to inform a national governance and policy framework for Australia. Results Australian policy makers have been slow to develop a coordinated plan. While the experience from other governments can guide our national policy, there are specific areas that require further consideration by Australian health experts. Key reforms involve the separation of policy and operational activities, multidisciplinary decision-making and oversight by the Australian Health Ministers’ Advisory Council for policy direction. Conclusion A formal national policy framework will guide the coordination of NBS services that can adapt to the needs of Australian children and families.

  14. Expanded newborn screening: social and ethical issues. (United States)

    Dhondt, Jean-Louis


    Newborn screening and genetic testing have expanded rapidly in the last decade with the advent of multiplex (e.g., tandem mass spectrometry) and/or DNA technologies. However, screening panels include a large number of disorders, which may not meet all of the traditional screening criteria, established in late 1960s, and used for years to justify screening programs. After a period of expansion driven by technological advances, many reports have reconsidered the justification of expanded programs. Many factors have contributed to test-panel discrepancies between countries. The test-panel review methodology, the way health benefits are weighed against harms, and the socioeconomic-political environment all play a role. Expansion of screening also requires reconsideration of the infrastructure (ideally, in the context of national plans for rare diseases) to support testing, counselling, education, treatment, and follow-up. Consequently, economic aspects cannot be ignored and can be a limitation for expansion. New ethical questions have emerged: risks of discrimination or stigmatization, respect of the autonomy of persons to make decisions, parental anxiety resulting from a false positive test (especially when reporting to parents screening results for untreatable conditions identified as by-products of screening), etc. For disorders where there is not yet confirmation of benefit, it may be prudent to recommend pilot screening and to have a mechanism that can be used to adapt or even to stop a program.

  15. Dissociated cultures of newborn mouse brain

    International Nuclear Information System (INIS)

    Wiesmann, U.N.; Hofmann, K.; Burkhart, T.; Herschkowitz, N.


    The metabolism of 35 SO 4 -sulfated lipids and mucopolysaccharides was studied in dissociated brain cell cultures from newborn albino mouse brains. The cultures were maintained under an atmosphere of 40% O 2 and 5% CO 2 in apparent good health up to 30 days. Early morphological examination of the dissociated cells demonstrated an initial partial reaggregation of the cells, which later settled and became confluent bilayered cultures. Cell proliferation measured by DNA and protein determination, morphological differentiation and biochemical differentiation took place in the dissociated brain cell cultures analogous in some respects to the in vivo situation. A timed increase in the synthesis of a myelin precursor, cerebroside 35 SO 4 , was observed after 6 to 8 days in culture (DIC). A peak of cerebroside sulfate was evident at 17 DIC. No stable sulfatide was observed at any time. Protein-bound macromolecular 35 SO 4 -MPS was synthetized and secreted from the cells into the culture medium. Maximal synthesis and secretion occurred at 8 DIC. This culture system proves to be a useful model for studying some aspects of differentiation of brain cells under external conditions. (author)

  16. Guidelines for procedural pain in the newborn (United States)

    Lago, Paola; Garetti, Elisabetta; Merazzi, Daniele; Pieragostini, Luisa; Ancora, Gina; Pirelli, Anna; Bellieni, Carlo Valerio


    Despite accumulating evidence that procedural pain experienced by newborn infants may have acute and even long-term detrimental effects on their subsequent behaviour and neurological outcome, pain control and prevention remain controversial issues. Our aim was to develop guidelines based on evidence and clinical practice for preventing and controlling neonatal procedural pain in the light of the evidence-based recommendations contained in the SIGN classification. A panel of expert neonatologists used systematic review, data synthesis and open discussion to reach a consensus on the level of evidence supported by the literature or customs in clinical practice and to describe a global analgesic management, considering pharmacological, non-pharmacological, behavioural and environmental measures for each invasive procedure. There is strong evidence to support some analgesic measures, e.g. sucrose or breast milk for minor invasive procedures, and combinations of drugs for tracheal intubation. Many other pain control measures used during chest tube placement and removal, screening and treatment for ROP, or for postoperative pain, are still based not on evidence, but on good practice or expert opinions. Conclusion: These guidelines should help improving the health care professional's awareness of the need to adequately manage procedural pain in neonates, based on the strongest evidence currently available.

  17. [Animal experimentation, animal welfare and scientific research]. (United States)

    Tal, H


    Hundreds of thousands of laboratory animals are being used every year for scientific experiments held in Israel, mostly mice, rats, rabbits, guinea pigs, and a few sheep, cattle, pigs, cats, dogs, and even a few dozen monkeys. In addition to the animals sacrificed to promote scientific research, millions of animals slain every year for other purposes such as meat and fine leather fashion industries. While opening a front against all is an impossible and perhaps an unjustified task, the state of Israel enacted the Animal Welfare (Animal Experimentation) Law (1994). The law aims to regulate scientific animal experiments and to find the appropriate balance between the need to continue to perform animal experiments for the advancement of research and medicine, and at the same time to avoid unnecessary trials and minimize animal suffering. Among other issues the law deals with the phylogenetic scale according to which experimental animals should be selected, experiments for teaching and practicing, and experiments for the cosmetic industry. This article discusses bioethics considerations in animal experiments as well as the criticism on the scientific validity of such experiments. It further deals with the vitality of animal studies and the moral and legal obligation to prevent suffering from laboratory animals.

  18. Vitamin D Deficiency among Newborns in Amman, Jordan (United States)

    Khuri-Bulos, Najwa; Lang, Ryan D.; Blevins, Meridith; Kudyba, Katherine; Lawrence, Lindsey; Davidson, Mario; Faouri, Samir; Halasa, Natasha B.


    Objective: Vitamin D deficiency is well recognized in selected Middle Eastern countries, but neonatal vitamin D status is not well studied in Jordan and other nearby countries. The aim of this study is to determine the prevalence of vitamin D deficiency in Jordanian newborns and risk factors associated with low levels. Methods: This is a prospective cohort study of newborn infants who were delivered at the Al Bashir Government Hospital in Amman, Jordan, from January 31, 2010, to January 27, 2011. Heel stick blood samples for 25-hydroxyvitamin D [25(OH)D] levels were obtained within 96 hours of birth. Maternal dress pattern, vitamin supplementation, smoke exposure during pregnancy, mode of delivery, gestational age, and birth weight were documented. Results: Samples were obtained from 3,731 newborns. Median gestational age was 39 weeks, median birth weight was 3.1 kilograms, median maternal age was 27 years, and median newborn 25(OH)D level was 8.6nmol/L. A total of 3,512 newborns (94.1%) in this study were vitamin D deficient (< 50 nmol/L). Lower gestational age, maternal smoke exposure, and birth during winter months were associated with lower infant vitamin D levels, while vitamin D supplementation and time spent outside during pregnancy were associated with higher vitamin D levels. Conclusions: The prevalence of severely low vitamin D levels in newborn infants in Amman, Jordan, is substantial, even in newborns born during the spring and summer months. Vitamin D supplementation is needed in this population. PMID:24373276

    STUDY QUESTION Is first trimester phthalate exposure associated with anogenital distance (AGD), a biomarker of prenatal androgen exposure, in newborns? SUMMARY ANSWER Concentrations of diethylhexyl phthalate (DEHP) metabolites in first trimester maternal urine samples are inversely associated with AGD in male, but not female, newborns. WHAT IS KNOWN ALREADY AGD is a sexually dimorphic measure reflecting prenatal androgen exposure. Prenatal phthalate exposure has been associated with shorter male AGD in multiple animal studies. Prior human studies, which have been limited by small sample size and imprecise timing of exposure and/or outcome, have reported conflicting results. STUDY DESIGN, SIZE, DURATION The Infant Development and the Environment Study (TIDES) is a prospective cohort study of pregnant women recruited in prenatal clinics in San Francisco, CA, Minneapolis, MN, Rochester, NY and Seattle, WA in 2010–2012. Participants delivered 787 infants; 753 with complete data are included in this analysis. PARTICIPANTS/MATERIALS, SETTING, METHODS Any woman over 18 years old who was able to read and write English (or Spanish in CA), who was <13 weeks pregnant, whose pregnancy was not medically threatened and who planned to deliver in a study hospital was eligible to participate. Analyses include all infants whose mothers provided a first trimester urine sample and who were examined at or shortly after birth. Specific gravity (SpG) adjusted concentrations of phthalate metabolites in first trimester urine samples were examined in relation to genital measurements. In boys (N = 366), we obtained two measures of anogenital distance (AGD) (anoscrotal distance, or AGDAS and anopenile distance, AGDAP) as well as penile width (PW). In girls (N = 373), we measured anofourchette distance (AGDAF) and anoclitoral distance (AGDAC). We used multivariable regression models that adjusted for the infant's age at exam, gestational age, weight-for-length Z-score, time of day of urine

  20. Morphology of the dorsal lingual papillae in the newborn panther and Asian black bear. (United States)

    Emura, S; Hayakawa, D; Chen, H; Shoumura, S


    The dorsal lingual surfaces of a newborn panther (Panthera pardus) and two newborn asian black bears (Selenarctos thibetanus) were examined by scanning electron microscopy (SEM). The tongues of the panther and asian black bear were about 40 mm in length and about 20 mm in width. Filiform, fungiform and vallate papillae were found. The filiform papillae were distributed over the entire dorsal surface of the tongue. In the panther, the filiform papillae on margin of the lingual apex were divided into two shapes which were horny or club-shaped papillae. The filiform papillae on the midportion were larger than those on the lateral region in size. The fungiform papillae also were divided into two shapes which were hemispherical or club-shaped papillae. In the asian black bear, the filiform papillae on the margin of the lingual apex were larger than those on margin of the panther tongue. The vallate papillae in the animals of two species were located on both sides of the posterior end of the lingual body. Each papilla was surrounded by a groove and crescent pad.

  1. Maternal-pup interaction disturbances induce long-lasting changes in the newborn rat pulmonary vasculature. (United States)

    Shifrin, Yulia; Sadeghi, Sina; Pan, Jingyi; Jain, Amish; Fajardo, Andres F; McNamara, Patrick J; Belik, Jaques


    The factors accounting for the pathological maintenance of a high pulmonary vascular (PV) resistance postnatally remain elusive, but neonatal stressors may play a role in this process. Cross-fostering in the immediate neonatal period is associated with adult-onset vascular and behavioral changes, likely triggered by early-in-life stressors. In hypothesizing that fostering newborn rats induces long-lasting PV changes, we evaluated them at 14 days of age during adulthood and compared the findings with animals raised by their biological mothers. Fostering resulted in reduced maternal-pup contact time when compared with control newborns. At 2 wk of age, fostered rats exhibited reduced pulmonary arterial endothelium-dependent relaxation secondary to downregulation of tissue endothelial nitric oxide synthase expression and tetrahydrobiopterin deficiency-induced uncoupling. These changes were associated with neonatal onset-increased ANG II receptor type 1 expression, PV remodeling, and right ventricular hypertrophy that persisted into adulthood. The pulmonary arteries of adult-fostered rats exhibited a higher contraction dose response to ANG II and thromboxane A2, the latter of which was abrogated by the oxidant scavenger Tempol. In conclusion, fostering-induced neonatal stress induces long-standing PV changes modulated via the renin-angiotensin system. Copyright © 2015 the American Physiological Society.

  2. Influence of antepartum administration of immunopotentiators on reproductive efficacy of buffalo and viability of their newborn

    Directory of Open Access Journals (Sweden)

    Atef M. Badr


    Full Text Available The authors determine the efficacy of prepartum immunopotentiators administered during late gestation on postpartum fertility, IgG levels and calf viability. Fifty buffalo were divided into five groups (10 animals in each group. Group I was the control group. Each animal in Group II received 30 ml intramuscularly of viteselen (1.7 mg sodium selenium and 150 mg vitamin E/ml. Each animal in Group III received a subcutaneous injection of bacillus Calmette-Guérin (BCG at 0.5 ml. In Group IV, each animal received 12.5 ml of levamisole hydrochloride intramuscularly, while those in Group V received 10 ml of ultra-corn subcutaneously. The immunopotentiators were administered according to each group 60 days prior to the anticipated date of parturition. Postpartum fertility was assessed by close observation and rectal examination after parturition. Colostrum from the dams and sera from the newborn were collected to estimate the level of immunoglobulin (IgG. Body weight, growth rate and viability of the calves were recorded after parturition. Prepartum treatment with viteselen reduced the period of foetal membrane expulsion by 2 h compared to the other groups. Concomitantly, the uterine involution period was significantly shorter in animals treated with viteselen and ultra-corn than in the other groups. Injection of viteselen, BCG or ultra-corn significantly reduced the calving to the first oestrus interval and length of postpartum service period (by 57, 54, 48 days and 67, 57, 44 days, respectively than the levamisole group. The IgG level was significantly higher in both the colostrum of the dam and in newborn serum after administration of immunopotentiating agents. Furthermore, the viteselen injection resulted in a significantly higher level of IgG in both dam colostrum (at parturition and calf serum in comparison to the other groups. The calves from viteselen and ultra-corn treated dams showed a higher growth rate and better health condition than the

  8. Off-label drug in the newborn

    Directory of Open Access Journals (Sweden)

    Laura Cuzzolin


    Full Text Available The lack of specific drugs and labelling recommendations for the neonatal population is a long-standing problem throughout the world. With the introduction of the Paediatric Regulation in 2007, in Europe tangible steps have been made to increase clinical research in children, but only a limited number of clinical trials included neonates that remain therapeutic orphans. This leads to a widespread use of medicines outside the terms indicated in the product license (off-label as regards dose, route of administration, indication, age group or in an unlicensed manner (formulations modified, extemporaneous preparations, imported medicines, chemicals used as drugs. This use, often made on the basis of a consolidated clinical experience in absence of other authorized options, does not imply that a drug is contraindicated or disapproved, but simply means that insufficient data are available to grant approval status and the risks and benefits of using a drug in a particular situation have not been examined. Given the importance that neonatal population not be denied of drugs that are clearly beneficial, an updated overview of the worldwide situation of off-label and unlicensed drug use in the newborn will be presented, by analyzing also the impact of recent legislative initiatives and the well recognized problems (increased risk of ineffective or toxic treatments, adverse drug reactions and medication errors. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

  9. Continuous Glucose Monitoring in Newborn Infants (United States)

    Thomas, Felicity; Signal, Mathew; Harris, Deborah L.; Weston, Philip J.; Harding, Jane E.; Shaw, Geoffrey M.


    Neonatal hypoglycemia is common and can cause serious brain injury. Continuous glucose monitoring (CGM) could improve hypoglycemia detection, while reducing blood glucose (BG) measurements. Calibration algorithms use BG measurements to convert sensor signals into CGM data. Thus, inaccuracies in calibration BG measurements directly affect CGM values and any metrics calculated from them. The aim was to quantify the effect of timing delays and calibration BG measurement errors on hypoglycemia metrics in newborn infants. Data from 155 babies were used. Two timing and 3 BG meter error models (Abbott Optium Xceed, Roche Accu-Chek Inform II, Nova Statstrip) were created using empirical data. Monte-Carlo methods were employed, and each simulation was run 1000 times. Each set of patient data in each simulation had randomly selected timing and/or measurement error added to BG measurements before CGM data were calibrated. The number of hypoglycemic events, duration of hypoglycemia, and hypoglycemic index were then calculated using the CGM data and compared to baseline values. Timing error alone had little effect on hypoglycemia metrics, but measurement error caused substantial variation. Abbott results underreported the number of hypoglycemic events by up to 8 and Roche overreported by up to 4 where the original number reported was 2. Nova results were closest to baseline. Similar trends were observed in the other hypoglycemia metrics. Errors in blood glucose concentration measurements used for calibration of CGM devices can have a clinically important impact on detection of hypoglycemia. If CGM devices are going to be used for assessing hypoglycemia it is important to understand of the impact of these errors on CGM data. PMID:24876618

  10. [2,3 diphosphoglycerate in preterm newborns]. (United States)

    Scopesi, F; Canini, S; Mazzella, M; Arioni, C; Lantieri, P; Serra, G


    It has been largely shown that during the first month of life, in the preterm neonate Hb levels and Hct percentages rapidly decrease, high HbF concentration persists and a high oxygen affinity occurs. Data are needed to establish the level at which 2,3 dyphosphoglycerate (2,3 DPG) interacts with the regulation of oxygen affinity. 24 samples, from eight uncomplicated preterm newborns (34.1 +/- 1.83 GW, 1869 +/- +/- 291 BW) obtained at the same time as those required for the clinical management of the infants, were collected on the 2nd, 7th and 14th day of life. Blood gases, total hemoglobin and hematocrit were obtained from 0.3 ml arterialised capillary blood. Assays of 2,3 DPG were made separately on 0.4 ml venous blood. As expected tHb concentration and Hct percentages significantly decreased from day 2 to day 14 in all eight cases. On the contrary 2,3 DPG and p50 values remained stable. Subsequently throughout the study period all neonates had an increased 2,3 DPG/Hb ratio that was significantly related with p50 at standard conditions (p < 0.05). Stable 2,3 DPG concentrations during all study period have been detected. The subsequent significant increased 2.3 DPG/Hb, ratio related to increased p50 values, could have a key role in a physiological mechanism aimed to ensure adequate oxygen delivery to the tissues and to counteract the higher oxygen affinity of fetal hemoglobin. A wider sample is needed to validate this hypothesis.

  11. Sonographic findings of normal newborn spinal cord

    International Nuclear Information System (INIS)

    Park, Chan Sup; Kim, Dong Gyu


    The authors performed spinal cord ultrasonography of 21 healthy newborn infants in Gyeongsang National University Hospital. Normal spinal cord revealed low echogenecity at that of cerebrospinal fluid and was demarcated by intense reflections from its dorsal and ventral surfaces. The central canal was routinely seen as a thin linear reflection in the center of the cord. The nerve roots making up the cauda equina formed a poorly defined collection of intense linear echoes extending from the conus. On real time image, the normal spinal cord exhibited rather slow and rhythmical anteroposterior movement within the subarachnoid fluid. A distinct and rapid vascular pulsation of the spinal cord was usually recognizable. The approximate level of vertebral bodies was determined as follows; most ventrally located vertebral body was thought to be L5 and S1 was seen slightly posterior to the L5 directed inferoposteriorly. According to the above criteria terminal portions of spinal cord were seen around the L2 body in 5 MHz and pointed termination of conus medullaris was clearly seen at L2-3 junction and in upper body of L3 by 7.5 MHz. So it would be better to examine by 5 MHz for spatial orientation and then by 7.5 MHz for more accurate examination. High-resolution, real-time ultrasonography was a safe, rapid screening technique for evaluation of the spinal cord in infants. Additional applications of spinal sonography may be possible in the evaluation of neonatal syringohydromyelia and meningocele as well as intraspinal cyst localization for possible percutaneous puncture by ultrasound guidance

    Full Text Available Objective: This study aimed to compare newborns anthropometric indices of housewives and employed women.Materials and Methods: This case control study compared newborns’ anthropometric indices (weight, length, head circumference and first minute APGAR between working women and housewives. Two hundred consecutive term pregnant women during active phase of labor without any pregnancy complications were evaluated. For each participant a questionnaire was filled by the researcher. Employed women according to their standing position during work time were divided into three groups: heavy, light and moderate jobs.   Results: The mean weight, length and head circumference of the newborns were higher in employed women (p=0.018, p<0.001, p=0.010, respectively. After eliminating effect of the interfering variables by using a general linear model, it was observed that the mother’s job has a direct influence on newborn's length and head circumference. But infant's weight was similar in two groups (p=0.340. The newborn's anthropometric indices and first minute APGAR had not significant difference in subgroups of job difficulty.Conclusion: Maternal job has a direct positive influence on newborn's length and head circumference. But infant's weight is not related to maternal job.

  14. Hemoglobinopathies in newborns from Salvador, Bahia, Northeast Brazil

    Directory of Open Access Journals (Sweden)

    Adorno Elisângela Vitória


    Full Text Available Hemoglobinopathies are hereditary disorders of the hemoglobin molecule with a high prevalence worldwide. Brazil has a prevalence of 0.1 to 0.3% of newborns with sickle cell anemia and 20.0 to 25.0% of heterozygous alpha2 thalassemia among African Brazilians. In the present study, we investigated the presence of variant hemoglobins and alpha2(3.7 Kb and alpha2(4.2 Kb thalassemia in newborns from Salvador, Bahia, Brazil. Samples of umbilical cord blood from a total of 590 newborns were analyzed, of which 57 (9.8% were FAS; 36 (6.5% FAC; one (0.2% SF; and five (0.9% FSC. One hundred fourteen (22.2% newborns had alpha2(3.7 Kb thalassemia, of whom 101 (19.7% were heterozygous and 13 (2.5% homozygous, showing statistical significance for hematological data between newborns with normal alpha genes and alpha2(3.7 Kb thalassemia carriers. The alpha2(4.2 Kb thalassemia was not found. Frequencies found in the present study confirm that hemoglobinopathies are a public health problem in Brazil, emphasizing the need for neonatal screening and genetic counseling programs.

  15. Current Issues and Challenges in the Use of Aerosolized Surfactant for Respiratory Distress Syndrome in the Newborns

    Directory of Open Access Journals (Sweden)

    Dion Darius Samsudin


    Full Text Available BACKGROUND: Surfactant replacement therapy is a recognized treatment for respiratory distress syndrome (RDS in the newborns. Over the past 30 years, human and animal trials have been performed regarding administration of aerosolized surfactant to the injured lung, however the result has been unsatisfactory when compared with instilled surfactant delivery via endotracheal tube (ETT. This review aims to investigate the current issues, challenges and future recommendation of aerosolized surfactant therapy. CONTENT: Five randomized clinical trials in humans and 13 animal trials met the inclusion criteria and were reviewed. Most animal trials agree that this method of treatment is feasible. However, human trials presented conflicting results, and generally showed it to be ineffective. When compared with surfactant delivery via ETT, aerosolized surfactant is less effective in improving respiratory function. SUMMARY: The current data from human trials does not support the implementation of aerosolized surfactant therapy to treat newborns with RDS. Further research is necessary to improve nebulization, delivery, distribution and deposition in the lung, to investigate aerosolized surfactant delivery via ETT and to determine the appropriate dose. KEYWORDS: surfactant, aerosol, prematurity, respiratory distress syndrome.

  16. Seeing the animal

    DEFF Research Database (Denmark)

    Harfeld, Jes Lynning; Cornou, Cecile; Kornum, Anna


    This article discusses the notion that the invisibility of the animalness of the animal constitutes a fundamental obstacle to change within current production systems. It is discussed whether housing animals in environments that resemble natural habitats could lead to a re-animalization...... of the animals, a higher appreciation of their moral significance, and thereby higher standards of animal welfare. The basic claim is that experiencing the animals in their evolutionary and environmental context would make it harder to objectify animals as mere bioreactors and production systems. It is argued...... that the historic objectification of animals within intensive animal production can only be reversed if animals are given the chance to express themselves as they are and not as we see them through the tunnel visions of economy and quantifiable welfare assessment parameters....

  17. Animal rights, animal minds, and human mindreading. (United States)

    Mameli, M; Bortolotti, L


    Do non-human animals have rights? The answer to this question depends on whether animals have morally relevant mental properties. Mindreading is the human activity of ascribing mental states to other organisms. Current knowledge about the evolution and cognitive structure of mindreading indicates that human ascriptions of mental states to non-human animals are very inaccurate. The accuracy of human mindreading can be improved with the help of scientific studies of animal minds. However, the scientific studies do not by themselves solve the problem of how to map psychological similarities (and differences) between humans and animals onto a distinction between morally relevant and morally irrelevant mental properties. The current limitations of human mindreading-whether scientifically aided or not-have practical consequences for the rational justification of claims about which rights (if any) non-human animals should be accorded.

  18. Growth hormone in intra-uterine growth retarded newborns. (United States)

    Setia, Sajita; Sridhar, M G; Bhat, Vishnu; Chaturvedula, Latha


    To study growth hormone levels in IUGR and healthy controls and its association with birth weight and ponderal index. We studied 50 Intra uterine growth retarded (IUGR) and 50 healthy newborns born at term by vaginal delivery in JIPMER, Pondicherry, India. Cord blood was collected at the time of delivery for measurement of growth hormone. When compared with healthy newborns, IUGR newborns had higher growth hormone levels (mean +/- SD, 23.5 +/- 15.6 vs 16.2 +/- 7.61 ngm/ml, P = 0.019). A negative correlation was identified between growth hormone levels and birth weight (r2 = - 0.22, P = 0.03) and ponderal index (r2 = - 0.36, P = 0.008). Correlation of growth hormone levels was much more confident with ponderal index than with birth weight. At birth IUGR infants display increased growth hormone levels which correlate with ponderal index much more confidently than with birth weight.

  19. Newborn screening for proximal urea cycle disorders: Current evidence supporting recommendations for newborn screening. (United States)

    Merritt, J Lawrence; Brody, Linnea L; Pino, Gisele; Rinaldo, Piero


    Current newborn screening (NBS) for urea cycle disorders (UCD) is incomplete as only distal UCDs are included in most NBS programs by measuring elevated amino acid concentrations. NBS for the proximal UCDs involves the detection in NBS spots of low citrulline values, a finding which is often overlooked because it is considered to be inadequate. We retrospectively analyzed NBS blood spots from known UCD patients comparing the utility of the Region 4 Stork (R4S) interpretive tools to conventional cutoff based interpretation. This study shows the utility of R4S tools in detecting all UCDs, and provides evidence to support the nomination to add proximal UCDs to the recommended uniform screening panel.

  20. Hemolytic disease of the fetus and newborn: managing the mother, fetus, and newborn. (United States)

    Delaney, Meghan; Matthews, Dana C


    Hemolytic disease of the fetus and newborn (HDFN) affects 3/100 000 to 80/100 000 patients per year. It is due to maternal blood group antibodies that cause fetal red cell destruction and in some cases, marrow suppression. This process leads to fetal anemia, and in severe cases can progress to edema, ascites, heart failure, and death. Infants affected with HDFN can have hyperbilirubinemia in the acute phase and hyporegenerative anemia for weeks to months after birth. The diagnosis and management of pregnant women with HDFN is based on laboratory and radiographic monitoring. Fetuses with marked anemia may require intervention with intrauterine transfusion. HDFN due to RhD can be prevented by RhIg administration. Prevention for other causal blood group specificities is less studied. © 2015 by The American Society of Hematology. All rights reserved.

  1. Neuroprotective intervention after hypoxia-ischemia may change intracerebral metabolic measures in a newborn piglet model

    DEFF Research Database (Denmark)

    Andelius, Ted Carl; Bøgh, Nikolaj; Pedersen, Mette Vestergaard

    Introduction Hypoxic-Ischemic Neonatal Encephalopathy (HIE) is a major contributor to neurological impairment and death in children. Due to the similarity with the human brain, newborn piglets are often used in studies of new treatments for HIE. Cell death after hypoxia ischemia (HI) occurs...... measured intracranial pressure (ICP), flow, temperature, and oxygen tension. By microdialysis we measured lactate, glucose, glycerol, and pyruvate. A NIRS-probe was placed on the right side of the head and aEEG electrodes were placed on each side. After 24 hours of stabilisation, HI was induced for 45....... Lactate/pyruvate ratio and ICP showed a parabolic pattern in the HI piglet. Conclusion We present a novel take on an already well-established animal model for HIE. We expect to provide basic knowledge of how interventions may affect intracerebral metabolic measures, pressure and gas...

  2. Piperidine alkaloids: human and food animal teratogens. (United States)

    Green, Benedict T; Lee, Stephen T; Panter, Kip E; Brown, David R


    Piperidine alkaloids are acutely toxic to adult livestock species and produce musculoskeletal deformities in neonatal animals. These teratogenic effects include multiple congenital contracture (MCC) deformities and cleft palate in cattle, pigs, sheep, and goats. Poisonous plants containing teratogenic piperidine alkaloids include poison hemlock (Conium maculatum), lupine (Lupinus spp.), and tobacco (Nicotiana tabacum) [including wild tree tobacco (Nicotiana glauca)]. There is abundant epidemiological evidence in humans that link maternal tobacco use with a high incidence of oral clefting in newborns; this association may be partly attributable to the presence of piperidine alkaloids in tobacco products. In this review, we summarize the evidence for piperidine alkaloids that act as teratogens in livestock, piperidine alkaloid structure-activity relationships and their potential implications for human health.

  3. Analysis of MicroRNA Expression in Newborns with Differential Birth Weight Using Newborn Screening Cards

    Directory of Open Access Journals (Sweden)

    Patricia Rodil-Garcia


    Full Text Available Birth weight is an early predictor for metabolic diseases and microRNAs (miRNAs are proposed as fetal programming participants. To evaluate the use of dried blood spots (DBS on newborn screening cards (NSC as a source of analyzable miRNAs, we optimized a commercial protocol to recover total miRNA from normal birth weight (NBW, n = 17–20, low birth weight (LBW, n = 17–20 and high birth weight (macrosomia, n = 17–20 newborns and analyzed the relative expression of selected miRNAs by stem-loop RT-qPCR. The possible role of miRNAs on the fetal programming of metabolic diseases was explored by bioinformatic tools. The optimized extraction of RNA resulted in a 1.2-fold enrichment of miRNAs respect to the commercial kit. miR-33b and miR-375 were overexpressed in macrosomia 9.8-fold (p < 0.001 and 1.7-fold, (p < 0.05, respectively and miR-454-3p was overexpressed in both LBW and macrosomia (19.7-fold, p < 0.001 and 10.8-fold, p < 0.001, respectively, as compared to NBW. Potential target genes for these miRNAs are associated to cyclic-guanosine monophosphate (cGMP-dependent protein kinase (PKG, mitogen-activated protein kinase (MAPK, type 2 diabetes, transforming growth factor-β (TGF-βand Forkhead box O protein (FoxO pathways. In summary, we improved a protocol for analyzing miRNAs from NSC and provide the first evidence that birth weight modifies the expression of miRNAs associated to adult metabolic dysfunctions. Our work suggests archived NSC are an invaluable resource in the search for fetal programming biomarkers.

  4. Evidence on Adrenaline Use in Resuscitation and Its Relevance to Newborn Infants: A Non-Systematic Review. (United States)

    Pinto, Merlin; Solevåg, Anne Lee; OʼReilly, Megan; Aziz, Khalid; Cheung, Po-Yin; Schmölzer, Georg M


    Guidelines for newborn resuscitation state that if the heart rate does not increase despite adequate ventilation and chest compressions, adrenaline administration should be considered. However, controversy exists around the safety and effectiveness of adrenaline in newborn resuscitation. The aim of this review was to summarise a selection of the current knowledge about adrenaline during resuscitation and evaluate its relevance to newborn infants. A search in PubMed, Embase, and Google Scholar until September 1, 2015, using search terms including adrenaline/epinephrine, cardiopulmonary resuscitation, death, severe brain injury, necrotizing enterocolitis, bronchopulmonary dysplasia, and adrenaline versus vasopressin/placebo. Adult data indicate that adrenaline improves the return of spontaneous circulation (ROSC) but not survival to hospital discharge. Newborn animal studies reported that adrenaline might be needed to achieve ROSC. Intravenous administration (10-30 μg/kg) is recommended; however, if there is no intravenous access, a higher endotracheal dose (50-100 μg/kg) is needed. The safety and effectiveness of intraosseous adrenaline remain undetermined. Early and frequent dosing does not seem to be beneficial. In fact, negative hemodynamic effects have been observed, especially with doses ≥30 μg/kg intravenously. Little is known about adrenaline in birth asphyxia and in preterm infants, but observations indicate that hemodynamics and neurological outcomes may be impaired by adrenaline administration in these conditions. However, a causal relationship between adrenaline administration and outcomes cannot be established from the few available retrospective studies. Alternative vasoconstrictors have been investigated, but the evidence is scarce. More research is needed on the benefits and risks of adrenaline in asphyxia-induced bradycardia or cardiac arrest during perinatal transition. © 2016 S. Karger AG, Basel.

  5. Midwives' Experiences, Education, and Support Needs Regarding Basic Newborn Resuscitation in Jordan. (United States)

    Kassab, Manal; Alnuaimi, Karimeh; Mohammad, Khitam; Creedy, Debra; Hamadneh, Shereen


    Newborns who are compromised at birth require rapid attention to stabilize their respiration attempts. Lack of knowledge regarding basic newborn resuscitation is a contributing factor to poor newborn health outcomes and increased mortality. The purpose of this study was to explore Jordanian midwives' experiences, education, and support needs to competently perform basic newborn resuscitation. Qualitative descriptive methodology was used to analyze a convenience sample of 20 midwives. A thematic approach was used to analyze the data. Participants discussed their experiences of basic newborn resuscitation including knowledge, skills, and barriers and suggested solutions to improve practice. Four themes were revealed: lack of knowledge and skills in newborn resuscitation, organizational constraints, inadequate teamwork, and educational needs. The midwives perceived that their ability to perform newborn resuscitation was hindered by lack of knowledge and skills in newborn resuscitation, organizational constraints (such as lack of equipment), and poor co-ordination and communication among team members. © The Author(s) 2015.

  6. The effect of maternal anemia on anthropometric measurements of newborns

    International Nuclear Information System (INIS)

    Telatar, Berrin; Comert, Serdar; Vitrinel, Ayca; Akin, Yasemin; Erginoz, Ethem


    To evaluate the relation between maternal prenatal hemoglobin concentration and neonatal anthropometric measurements. All pregnant women who gave birth at the Obstetrics Department of Dr. LK Kartal Training and Research Hospital, Istanbul, Turkey, from January 1, 2005 to December 31, 2006, and their newborns were included in this prospective, cross-sectional study. The newborns weight, height, head, and chest circumference were recorded. Mothers with hemoglobin concentration less than 11g/dl were evaluated as anemic. The anemic mothers were then grouped into 3 categories according to the corresponding hemoglobin concentration: mild (10.9-9.0g/dl), moderate (8.9-7.0 g/dl), and severe anemic (less than 7 g/dl). The anthropometric measurements of newborns from non-anemic and anemic mother groups were compared. Of the 3688 pregnant women, 1588 (43%) were found to be anemic. Among the anemic mothers, 1245 had mild (78.5%), 311 had moderate (19.5%), and 32 (2%) had severe anemia. The anthropometric measurements (height, weight, head and chest circumference) of newborns of anemic and non-anemic mother groups showed a statistically significant difference (p=0.036, p=0.044, p=0.013, and p=0.0002). There was a statistically significant difference in height, weight, and chest circumference of newborns of severe anemic and mild anemic mothers (p=0.017, p=0.008 and p=0.02). The height (1.1 cm), weight (260 g), head (0.42 cm), and chest (1 cm) circumference of neonates in the severe anemic group is less than the mild anemic group. Anemia during pregnancy affect the anthropometric measurements of a newborn. Severe anemia had significant negative effect on neonatal anthropometric measurements. (author)

  7. [Maternal autoimmune thyroid disease: relevance for the newborn]. (United States)

    Temboury Molina, M Carmen; Rivero Martín, M José; de Juan Ruiz, Jesús; Ares Segura, Susana


    Autoimmune thyroid disease is amongst the most frequent endocrine disorders during pregnancy. It is associated with an increase in perinatal morbidity, congenital defects, neurological damage, fetal and neonatal thyroid dysfunction. Maternal thyroid hormones play a key role in child neurodevelopment. We aimed to evaluate the thyroid function and the clinical course of neonates born from mothers with autoimmune thyroid disease during the first months of life in order to define the follow-up. We monitored thyroid function and clinical status during the first months in 81 newborns of mothers with autoimmune thyroid disease; 16 had Graves disease and 65 autoimmune thyroiditis. A percentage of 4.93 newborns had congenital defects, and 8.64% neonates showed an increase in thyrotropin (TSH) (>9.5 μUI/mL 2 times) and required thyroxin within the first month of life. A 85.7% of these showed a negative newborn screening (due to a later increase of TSH). A higher TSH value in the newborn was related to an older age of the mother, higher levels of thyroid peroxidase (TPO) antibody during pregnancy and lower birth weight. A higher free thyroxine (FT4) value in the newborn was related to fewer days of life and mothers with Graves disease. We recommend the evaluation of TSH, T4 and TPO antibodies before 10 weeks in all pregnant women with follow-up if maternal thyroid autoimmunity or disorders is detected. It is also recommended to test children's serum TSH and FT4 at 48 h of life in newborns of mothers with autoimmune thyroid disease and repeat them between the 2nd and 4th week in children with TSH>6 μUI/mL. Careful endocrine follow-up is advised in pregnant women and children if hyperthyroidism is detected. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

  8. Reducing radiation exposure in newborns with birth head trauma

    Directory of Open Access Journals (Sweden)

    Irina A. Kriukova


    Full Text Available Background. Birth head trauma causing intracranial injury is one of the most common causes of neonatal mortality and morbidity. In case of suspected cranial fractures and intracranial hematomas, diagnostic methods involving radiation, such as x-ray radiography and computed tomography, are recommended. Recently, an increasing number of studies have highlighted the risk of cancer complications associated with computed tomography in infants. Therefore, diagnostic methods that reduce radiation exposure in neonates are important. One such method is ultrasonography (US. Aim. We evaluated US as a non-ionizing radiation method for diagnosis of cranial bone fractures and epidural hematomas in newborns with cephalohematomas or other birth head traumas. Material and methods. The study group included 449 newborns with the most common variant of birth head trauma: cephalohematomas. All newborns underwent transcranial-transfontanelle US for detection of intracranial changes and cranial US for visualization of bone structure in the cephalohematoma region. Children with ultrasonic signs of cranial fractures and epidural hematomas were further examined at a children’s hospital by x-ray radiography and/or computed tomography. Results and discussion. We found that cranial US for diagnosis of cranial fractures and transcranial-transfontanelle US for diagnosis of epidural hematomas in newborns were highly effective. In newborns with parietal cephalohematomas (444 children, 17 (3.8% had US signs of linear fracture of the parietal bone, and 5 (1.1% had signs of ipsilateral epidural hematoma. Epidural hematomas were visualized only when US was performed through the temporal bone and not by using the transfontanelle approach. Sixteen cases of linear fractures and all epidural hematomas were confirmed by computed tomography. Conclusion. The use of US diagnostic methods reduced radiation exposure in newborns with birth head trauma. US methods (transcranial

  9. Weaning newborn infants from mechanical ventilation

    Directory of Open Access Journals (Sweden)

    Paolo Biban


    Full Text Available Invasive mechanical ventilation is a life-saving procedure which is largely used in neonatal intensive care units, particularly in very premature newborn infants. However, this essential treatment may increase mortality and cause substantial morbidity, including lung or airway injuries, unplanned extubations, adverse hemodynamic effects, analgosedative dependency and severe infectious complications, such as ventilator-associated pneumonia. Therefore, limiting the duration of airway intubation and mechanical ventilator support is crucial for the neonatologist, who should aim to a shorter process of discontinuing mechanical ventilation as well as an earlier appreciation of readiness for spontaneous breathing trials. Unfortunately, there is scarce information about the best ways to perform an effective weaning process in infants undergoing mechanical ventilation, thus in most cases the weaning course is still based upon the individual judgment of the attending clinician. Nonetheless, some evidence indicate that volume targeted ventilation modes are more effective in reducing the duration of mechanical ventilation than traditional pressure limited ventilation modes, particularly in very preterm babies. Weaning and extubation directly from high frequency ventilation could be another option, even though its effectiveness, when compared to switching and subsequent weaning and extubating from conventional ventilation, is yet to be adequately investigated. Some data suggest the use of weaning protocols could reduce the weaning time and duration of mechanical ventilation, but better designed prospective studies are still needed to confirm these preliminary observations. Finally, the implementation of short spontaneous breathing tests in preterm infants has been shown to be beneficial in some centres, favoring an earlier extubation at higher ventilatory settings compared with historical controls, without worsening the extubation failure rate.

  16. Carotenoids in Marine Animals (United States)

    Maoka, Takashi


    Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

    Yin-Hsiu Chien


    Conclusion: Newborn screening to measure the number of TREC copies successfully identifies newborns with T-cell lymphopenia, 22q11.2 microdeletion syndrome, and other high-risk conditions. Taken together, the incidence of T-cell lymphopenia in apparently healthy newborns is more than 1 in 11,821, and further attention to their immune functions is warranted.

    Cardoso, Sandra Maria Schefer; Kozlowski, Lorena de Cássia; Lacerda, Adriana Bender Moreira de; Marques, Jair Mendes; Ribas, Angela


    The incorporation of technologies in the care of infants has contributed to increased survival; however, this has turned neonatal unit into a noisy environment. To evaluate the physiological and functional effects resulting from the exposure to noise on low-weight newborns in incubators in a neonatal unit. Prospective, observational, quantitative, exploratory, descriptive study. The adopted statistical method included tables of frequency, descriptive statistics, and Student's t-test, with a 0.05 level of significance. As data collection tools, the environmental noise and the noise inside of the incubator were evaluated, and the Assessment of Preterm Infant Behavior scale was used to assess premature newborn behavior and projected specifically to document the neurobehavioral functioning of preterm infants. The data collection occurred from September of 2012 to April of 2013; 61 low-weight newborns admitted in the neonatal unit and in incubators were observed. Significant differences in the variables heart rate and oxygen saturation were noted when newborns were exposed to noise. Low-weight neonates in incubators present physiological alterations when facing discomfort caused by environmental noise in neonatal units.

    Procaccini, Diane; Curley, Ann L Cupp; Goldman, Martha


    It is accepted that newborns lose weight in the first few days of life. Baby-Friendly practices that support breastfeeding may affect newborn weight loss. The objective of this study were: 1) To determine whether Baby-Friendly practices are associated with term newborn weight loss day 0-2 in three feeding categories (exclusively breastfed, mixed formula fed and breastfed, and formula fed). 2) To determine whether Baby-Friendly practices increase exclusive breast feeding rates in different ethnic populations. This was a retrospective case-control study. Term newborn birth weight, neonatal weights days 0-2, feeding type, type of birth, and demographic information were collected for 1,000 births for the year before Baby-Friendly designation (2010) and 1,000 in 2013 (after designation). Ultimately 683 in the first group and 518 in the second met the inclusion criteria. Mean weight loss decreased day 0-2 for infants in all feeding types after the initiation of Baby-Friendly practices. There was a statistically significant effect of Baby-Friendly designation on weight loss for day 0-2 in exclusively breastfed infants (p Baby-Friendly practices were put in place. There was a decrease in mean weight loss day 0-2 regardless of feeding type after Baby-Friendly designation. Exclusive breast feeding increased in the presence of Baby-Friendly practices.

    Andrezza Braga Soares da Silva


    Full Text Available The neonatology science is, in Veterinary Medicine, studying the post-birth to the development of certain characteristics of resistance, which for canines occurs until the second week of life. The newborn requires a precise approach given the particularities of their physiology and immunology extremely immature. The histological study elucidates problems morphological and functional abnormalities, as it provides a reliable and microscopic analysis. Aimed to analyze trachea and lung of newborn dogs through techniques of basic histology. We used five neonates that died postpartum. These were weighed, measured and dissected. Proceeded to the extraction of the trachea, bronchus and lung for submitting these samples to histological routine. The tracheal tissue presents a pseudostratified columnar ciliated epithelium with globet cells, a small amount of glands in the lamina propria and hyaline cartilage not fully developed. As regards the bronchial tissue may be observed well defined layers, pulmonary pseudostratified columnar ciliated epithelium with goblet cells in the lamina propria several bundles of smooth muscle and thick vascularized tissue. Likewise, the signs of bronchial cartilage present under development. The bronchioles also feature the common pulmonary epithelium and lamina propria also normal pens without smooth muscle. The bags alveolar lung cells showed typical. The lung tissues of newborn dogs present is still in development stage. It is possible to understand patterns of histogenesis and morphogenesis in newborn dogs.

  15. Fuzzy object models for newborn brain MR image segmentation (United States)

    Kobashi, Syoji; Udupa, Jayaram K.


    Newborn brain MR image segmentation is a challenging problem because of variety of size, shape and MR signal although it is the fundamental study for quantitative radiology in brain MR images. Because of the large difference between the adult brain and the newborn brain, it is difficult to directly apply the conventional methods for the newborn brain. Inspired by the original fuzzy object model introduced by Udupa et al. at SPIE Medical Imaging 2011, called fuzzy shape object model (FSOM) here, this paper introduces fuzzy intensity object model (FIOM), and proposes a new image segmentation method which combines the FSOM and FIOM into fuzzy connected (FC) image segmentation. The fuzzy object models are built from training datasets in which the cerebral parenchyma is delineated by experts. After registering FSOM with the evaluating image, the proposed method roughly recognizes the cerebral parenchyma region based on a prior knowledge of location, shape, and the MR signal given by the registered FSOM and FIOM. Then, FC image segmentation delineates the cerebral parenchyma using the fuzzy object models. The proposed method has been evaluated using 9 newborn brain MR images using the leave-one-out strategy. The revised age was between -1 and 2 months. Quantitative evaluation using false positive volume fraction (FPVF) and false negative volume fraction (FNVF) has been conducted. Using the evaluation data, a FPVF of 0.75% and FNVF of 3.75% were achieved. More data collection and testing are underway.

    Objective: To determine the prevalence and etiology of respiratory distress in the newborns delivered over the period of one year from 1st January 2008 to 31st Dec 2008. Study Design: A descriptive study Place and Duration of Study: The study was conducted in Armed Forces Hospital Sharurah Kingdom of Saudi Arabia over a period of one year from January 2008 to Dec 2008 Patients and methods: All live newborns delivered at Armed Forces Hospital Sharurah during the study period were included and observed for development of respiratory distress. Results: All newborns (n=659), delivered at this hospital over the period of 12 months, were observed for respiratory distress. The overall prevalence of respiratory distress (RD) was 4.24%. Prevalence was 19.7% in preterm and 2.3% in full term. Transient tachypnea of newborn(TTN) was found to be the commonest 35.7% cause of Respiratory Distress (RD) followed by Hyaline membrane disease (HMD) 25%, meconium aspiration syndrome (MAS) 17.9%, congenital pneumonia 7.1% and other congenital anomalies 14.3%. TTN was found to be common among both term and preterm babies, while hyaline membrane disease was seen among preterm, and meconium aspiration syndrome among term and post term babies. Conclusion: Respiratory distress is a common neonatal problem with significant morbidity and mortality. Majority of cases are due to TTN followed by hyaline membrane disease and meconium aspiration syndrome. (author)

  20. Financing state newborn screening programs: sources and uses of funds. (United States)

    Johnson, Kay; Lloyd-Puryear, Michele A; Mann, Marie Y; Ramos, Lauren Raskin; Therrell, Bradford L


    Financing for newborn screening is different from virtually all other public health programs. All except 5 screening programs collect fees as the primary source of program funding. A fee-based approach to financing newborn screening has been adopted by most states, to ensure consistent funding for this critical public health activity. Two types of data are reported here, ie, primary data from a survey of 37 state public health agencies and findings from exploratory case studies from 7 states. Most of the programs that participated in this survey (73%) reported that their newborn screening funding increased between 2002 and 2005, typically through increased fees and to a lesser extent through Medicaid, Title V Maternal and Child Health Services Block Grant, and state general revenue funding. All of the responding states that collect fees (n = 31) use such funds to support laboratory expenses, and most (70%) finance short-term follow-up services and program management. Nearly one half (47%) finance longer-term follow-up services, case management, or family support beyond diagnosis. Other states (43%) finance genetic or nutritional counseling and formula foods or treatment. Regardless of the source of funds, the available evidence indicates that states are committed to maintaining their programs and securing the necessary financing for the initial screening through diagnosis. Use of federal funding is currently limited; however, pressure to provide dedicated federal funding would likely increase if national recommendations for a uniform newborn screening panel were issued.

    Gentil Gomes da Fonseca Filho


    Full Text Available Objective: To evaluate thermal and cardiorespiratory adaptation during hot tub bath and shower in healthy newborns in the first hours of life. Study design: This is a randomized blind controlled trial, registered in ReBEC (No. RBR-4z26f3 with 184 newborns divided into hot tub group (n=84 and shower (n=100. Newborns from intervention group were immersed in a hot tub with warm water up to the neck, without exposure to air flow, and control group received traditional shower. Heart rate, respiratory rate and temperature were measured before and immediately after bath by an investigator blinded to the type of bath. Results: Groups were similar in gender, gestational age, birth weight, Apgar score at 5th minute and hours of life, p => 0.05. To analyze thermal and cardiorespiratory adjustments, difference between post-bath variables and pre-bath was calculated. In this analysis, it was found statistically significant difference between two types of bath regarding heart rate, respiratory rate and temperature. Hot tub bath decreases heart and respiratory rates and increases temperature, whereas shower provides the opposite effect (0.0001. Conclusion: This study demonstrates that hot tub baths and shower, in healthy newborns, promote thermal and cardiorespiratory adaptations, reflecting thermal, cardiac and respiratory positive reactions after hot tub bath.

    To develop a consensus definition of growth restriction in the newborn that can be used clinically to identify newborn infants at risk and in research to harmonize reporting and definition in the current absence of a gold standard. An international panel of pediatric leaders in the field of neonatal growth were invited to participate in an electronic Delphi procedure using standardized methods and predefined consensus rules. Responses were fed back at group-level and the list of participants was provided. Nonresponders were excluded from subsequent rounds. In the first round, variables were scored on a 5-point Likert scale; in subsequent rounds, inclusion of variables and cut-offs were determined with a 70% level of agreement. In the final round participants selected the ultimate algorithm. In total, 57 experts participated in the first round; 79% completed the procedure. Consensus was reached on the following definition: birth weight less than the third percentile, or 3 out of the following: birth weight definition for growth restriction in the newborn. This definition recognizes that infants with birth weights 10th percentile can be growth restricted. This definition can be adopted in clinical practice and in clinical trials to better focus on newborns at risk, and is complementary to the previously determined definition of fetal growth restriction.

  17. Sucrose and warmth for analgesia in healthy newborns: an RCT. (United States)

    Gray, Larry; Garza, Elizabeth; Zageris, Danielle; Heilman, Keri J; Porges, Stephen W


    Increasing data suggest that neonatal pain has long-term consequences. Nonpharmacologic techniques (sucrose taste, pacifier suckling, breastfeeding) are effective and now widely used to combat minor neonatal pain. This study examined the analgesic effect of sucrose combined with radiant warmth compared with the taste of sucrose alone during a painful procedure in healthy full-term newborns. A randomized, controlled trial included 29 healthy, full-term newborns born at the University of Chicago Hospital. Both groups of infants were given 1.0 mL of 25% sucrose solution 2 minutes before the vaccination, and 1 group additionally was given radiant warmth from an infant warmer before the vaccination. We assessed pain by comparing differences in cry, grimace, heart rate variability (ie, respiratory sinus arrhythmia), and heart rate between the groups. The sucrose plus warmer group cried and grimaced for 50% less time after the vaccination than the sucrose alone group (P < .05, respectively). The sucrose plus warmer group had lower heart rate and heart rate variability (ie, respiratory sinus arrhythmia) responses compared with the sucrose alone group (P < .01), reflecting a greater ability to physiologically regulate in response to the painful vaccination. The combination of sucrose and radiant warmth is an effective analgesic in newborns and reduces pain better than sucrose alone. The ready availability of this practical nonpharmacologic technique has the potential to reduce the burden of newborn pain. Copyright © 2015 by the American Academy of Pediatrics.

    The objective of this study was to observe possible interactions between the renin-angiotensin and nitrergic systems in chronic hypoxia-induced pulmonary hypertension in newborn piglets. Thirteen chronically instrumented newborn piglets (6.3 ± 0.9 days; 2369 ± 491 g) were randomly assigned to receive saline (placebo, P) or the AT{sub 1} receptor (AT{sub 1}-R) blocker L-158,809 (L) during 6 days of hypoxia (FiO{sub 2} = 0.12). During hypoxia, pulmonary arterial pressure (Ppa; P < 0.0001), pulmonary vascular resistance (PVR; P < 0.02) and the pulmonary to systemic vascular resistance ratio (PVR/SVR; P < 0.05) were significantly attenuated in the L (N = 7) group compared to the P group (N = 6). Western blot analysis of lung proteins showed a significant decrease of endothelial NOS (eNOS) in both P and L animals, and of AT{sub 1}-R in P animals during hypoxia compared to normoxic animals (C group, N = 5; P < 0.01 for all groups). AT{sub 1}-R tended to decrease in L animals. Inducible NOS (iNOS) did not differ among P, L, and C animals and iNOS immunohistochemical staining in macrophages was significantly more intense in L than in P animals (P < 0.01). The vascular endothelium showed moderate or strong eNOS and AT{sub 1}-R staining. Macrophages and pneumocytes showed moderate or strong iNOS and AT{sub 1}-R staining, but C animals showed weak iNOS and AT{sub 1}-R staining. Macrophages of L and P animals showed moderate and weak AT{sub 2}-R staining, respectively, but the endothelium of all groups only showed weak staining. In conclusion, pulmonary hypertension induced by chronic hypoxia in newborn piglets is partially attenuated by AT{sub 1}-R blockade. We suggest that AT{sub 1}-R blockade might act through AT{sub 2}-R and/or Mas receptors and the nitrergic system in the lungs of hypoxemic newborn piglets.

    The Uganda Newborn Study (UNEST) was a two-arm cluster Randomized Control Trial to study the effect of pregnancy and postnatal home visits by local community health workers called 'Village Health Teams' (VHT) coupled with health systems strengthening. To inform programme planning and decision making, additional economic and financial costs of community and facility components were estimated from the perspective of the provider using the Excel-based Cost of Integrating Newborn Care Tool. Additional costs excluded costs already paid by the government for the routine health system and covered design, set-up, and 1-year implementation phases. Improved efficiency was modelled by reducing the number of VHT per village from two to one and varying the number of home visits/mother, the programme's financial cost at scale was projected (population of 100 000). 92% of expectant mothers (n = 1584) in the intervention area were attended by VHTs who performed an average of three home visits per mother. The annualized additional financial cost of the programme was $83 360 of which 4% ($3266) was for design, 24% ($20 026) for set-up and 72% ($60 068) for implementation. 56% ($47 030) went towards health facility strengthening, whereas 44% ($36 330) was spent at the community level. The average cost/mother for the community programme, excluding one-off design costs, amounted to $22.70 and the average cost per home visit was $7.50. The additional cost of the preventive home visit programme staffed by volunteer VHTs represents $1.04 per capita, 1.8% of Uganda's public health expenditure per capita ($59.00). If VHTs were to spend an average of 6 h a week on the programme, costs per mother would drop to $13.00 and cost per home visit to $3.20, in a population of 100 000 at 95% coverage. Additional resources are needed to rollout the government's VHT strategy nationally, maintaining high quality and linkages to quality facility-based care. © The Author 2017. Published by Oxford

  4. Neurodevelopment in newborns: a sample entropy analysis of electroencephalogram

    International Nuclear Information System (INIS)

    Zhang, Dandan; Ding, Haiyan; Liu, Yunfeng; Ding, Haishu; Zhou, Congle; Ye, Datian


    The present paper investigates the neural ontogeny of newborns in view of electroencephalogram (EEG) complexity during active sleep (AS) and quiet sleep (QS). Sample entropy (SampEn) is applied to EEG recordings from 168 newborns with postmenstrual age (PMA) ranging from 25 to 60 weeks. The relationship between neurodevelopment and PMA is then explored according to the statistical analysis of the median and interquartile range of SampEn curves. It is found that SampEn of EEG during AS is higher than that during QS. SampEn increases during both AS and QS before about 42 weeks in PMA while it ceases its increase in QS and even decreases in AS after newborns reaching term age. A distinct decrease in the interquartile range of SampEn is found with increasing PMA (from 25 to about 50 weeks), followed by maintenance of low fluctuation in SampEn curves. The study in this paper sets the stage for exhaustive investigation of the SampEn of EEG during brain maturation in newborns. And it could be hoped that SampEn in sleep EEG might be a useful parameter against which delays and aberrations in brain maturation might be tested. The SampEn changes during brain maturation also offer functional clues about neurodevelopment, based on which further explorations could be done. The significance of this paper is the discovery of the decrease in EEG complexity after newborns reaching term. Although some potential neurophysiologic reasons are given, this new discovery might require more study to investigate. In addition, the fluctuation of EEG complexity is analyzed for the first time, which helps to understand the EEG maturation in neurodevelopment

  5. Fragile X protein in newborn dried blood spots. (United States)

    Adayev, Tatyana; LaFauci, Giuseppe; Dobkin, Carl; Caggana, Michele; Wiley, Veronica; Field, Michael; Wotton, Tiffany; Kascsak, Richard; Nolin, Sarah L; Glicksman, Anne; Hosmer, Nicole; Brown, W Ted


    The fragile X syndrome (FXS) results from mutation of the FMR1 gene that prevents expression of its gene product, FMRP. We previously characterized 215 dried blood spots (DBS) representing different FMR1 genotypes and ages with a Luminex-based immunoassay (qFMRP). We found variable FMRP levels in the normal samples and identified affected males by the drastic reduction of FMRP. Here, to establish the variability of expression of FMRP in a larger random population we quantified FMRP in 2,000 anonymous fresh newborn DBS. We also evaluated the effect of long term storage on qFMRP by retrospectively assaying 74 aged newborn DBS that had been stored for 7-84 months that included normal and full mutation individuals. These analyses were performed on 3 mm DBS disks. To identify the alleles associated with the lowest FMRP levels in the fresh DBS, we analyzed the DNA in the samples that were more than two standard deviations below the mean. Analysis of the fresh newborn DBS revealed a broad distribution of FMRP with a mean approximately 7-fold higher than that we previously reported for fresh DBS in normal adults and no samples whose FMRP level indicated FXS. DNA analysis of the lowest FMRP DBS showed that this was the low extreme of the normal range and included a female carrying a 165 CGG repeat premutation. In the retrospective study of aged newborn DBS, the FMRP mean of the normal samples was less than 30% of the mean of the fresh DBS. Despite the degraded signal from these aged DBS, qFMRP identified the FXS individuals. The assay showed that newborn DBS contain high levels of FMRP that will allow identification of males and potentially females, affected by FXS. The assay is also an effective screening tool for aged DBS stored for up to four years.

    Full Text Available Animism is often described as the imputation of life to inert objects. Such imputation is more typical of people in western societies who dream of finding life on other planets than of indigenous peoples to whom the label of animism has classically been applied. These peoples are united not in their beliefs but in a way of being that is alive and open to a world in continuous birth. In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

  9. Occupational Animal Allergy. (United States)

    Stave, Gregg M


    This review explores animal allergen exposure in research laboratories and other work settings, focusing on causes and prevention. (1) Consistent with the hygiene hypothesis, there is new evidence that early childhood exposure to pets produces changes in the gut microbiome that likely lead to a lower risk of allergy. (2) Anaphylaxis from laboratory animal bites occurs more frequently than suggested by prior literature. (3) Animal allergens represent an occupational hazard in a wide variety of work settings ranging from fields that work with animals to public settings like schools and public transportation where allergens are brought into or are present in the workplace. Exposure to animal allergens can result in allergy, asthma, and anaphylaxis. Animal allergy has been most studied in the research laboratory setting, where exposure reduction can prevent the development of allergy. Similar prevention approaches need to be considered for other animal work environments and in all settings where animal allergens are present.

  14. Permissive hypercapnia for the prevention of morbidity and mortality in mechanically ventilated newborn infants. (United States)

    Woodgate, P G; Davies, M W


    Experimental animal data and uncontrolled, observational studies in human infants have suggested that hyperventilation and hypocapnia may be associated with increased pulmonary and neurodevelopmental morbidity. Protective ventilatory strategies allowing higher levels of arterial CO2 (permissive hypercapnia) are now widely used in adult critical care. The aggressive pursuit of normocapnia in ventilated newborn infants may contribute to the already present burden of lung disease. However, the safe or ideal range for PCO2 in this vulnerable population has not been established. To assess whether, in mechanically ventilated neonates, a strategy of permissive hypercapnia improves short and long term outcomes (esp. mortality, duration of respiratory support, incidence of chronic lung disease and neurodevelopmental outcome). Standard strategies of the Cochrane Neonatal Review Group were used. Searches were made of the Oxford Database of Perinatal Trials, MEDLINE, CINAHL, and Current Contents. Searches were also made of previous reviews including cross-referencing, abstracts, and conference and symposia proceedings published in Pediatric Research. All randomised controlled trials in which a strategy of permissive hypercapnia was compared with conventional strategies aimed at achieving normocapnia (or lower levels of hypercapnia) in newborn infants who are mechanically ventilated were eligible. Standard methods of the Cochrane Neonatal Review Group were used. Trials identified by the search strategy were independently reviewed by each author and assessed for eligibility and trial quality. Data were extracted separately. Differences were compared and resolved. Additional information was requested from trial authors. Only published data were available for review. Results are expressed as relative risk and risk difference for dichotomous outcomes, and weighted mean difference for continuous variables. Two trials involving 269 newborn infants were included.

  15. Effects of hyperbaric, normobaric and hypobaric oxygen supplementation on retinal vessels in newborn rats: a preliminary study. (United States)

    Ricci, B


    An experimental study was conducted on eight litters of newborn rats to evaluate the effects of supplemental oxygen administration on the retinal vasculature. The animals and their mothers were kept inside a pressure chamber and treated for the first 5 days of life. On the sixth day, they were removed and kept for five more days under room air and normobaric conditions. Three litters received continuous flow oxygen at 80% at a compression pressure of +81 kPa, one litter oxygen at 80% at a pressure of -39.5 kPa atms and three other litters received oxygen at 80% under normobaric conditions. The eighth litter was treated with room air oxygen at a compression pressure of +81 kPa. A severe retinopathy with marked retinal neovascularization was seen only in the newborn animals of the litters that received oxygen supplementation under normobaric or hypobaric conditions. Retinal vessels showed no pathological changes in the litters treated with hyperbaric normoxia or hyperoxia. It is possible to hypothesize that the prolonged period of oxygen supplementation failed to produce harmful effects on the retinal vasculature because the moderate hyperbarism caused mild retinal and choroidal vasoconstriction thus preventing excessive oxygen transport to the inner retina from the choroid during hyperoxia without inducing structural damage to the retinal tissue.

  17. Recommendations for newborn screening for galactokinase deficiency: A systematic review and evaluation of Dutch newborn screening data. (United States)

    Stroek, Kevin; Bouva, Marelle J; Schielen, Peter C J I; Vaz, Frédéric M; Heijboer, Annemieke C; de Jonge, Robert; Boelen, Anita; Bosch, Annet M


    Galactokinase (GALK) deficiency causes cataract leading to severe developmental consequences unless treated early. Because of the easy prevention and rapid reversibility of cataract with treatment, the Dutch Health Council advised to include GALK deficiency in the Dutch newborn screening program. The aim of this study is to establish the optimal screening method and cut-off value (COV) for GALK deficiency screening by performing a systematic review of the literature of screening strategies and total galactose (TGAL) values and by evaluating TGAL values in the first week of life in a cohort of screened newborns in the Netherlands. Systematic literature search strategies in OVID MEDLINE and OVID EMBASE were developed and study selection, data collection and analyses were performed by two independent investigators. A range of TGAL values measured by the Quantase Neonatal Total Galactose screening assay in a cohort of Dutch newborns in 2007 was evaluated. Eight publications were included in the systematic review. All four studies describing screening strategies used TGAL as the primary screening marker combined with galactose-1-phosphate uridyltransferase (GALT) measurement that is used for classical galactosemia screening. TGAL COVs of 2200 μmol/L, 1665 μmol/L and 1110 μmol/L blood resulted in positive predictive values (PPV) of 100%, 82% and 10% respectively. TGAL values measured in the newborn period were reported for 39 GALK deficiency patients with individual values ranging from 3963 to 8159 μmol/L blood and 2 group values with mean 8892 μmol/L blood (SD ± 5243) and 4856 μmol/L blood (SD ± 461). Dutch newborn screening data of 72,786 newborns from 2007 provided a median TGAL value of 110 μmol/L blood with a range of 30-2431 μmol/L blood. Based on TGAL values measured in GALK deficiency patients reported in the literature and TGAL measurements in the Dutch cohort by newborn screening we suggest to perform the GALK screening with

  18. Screening for congenital hypothyroidism (CH) among Filipino newborn infants. Philippine Newborn Screening Study Group. (United States)

    Fagela-Domingo, C; Padilla, C D; Cutiongco, E M


    From June 1996 to June 1998 a total of 62.841 newborn infants were screened for congenital hypothyroidism with thyroid stimulating hormone assay as a primary test. The method used was an immunofluorescent assay using the DELFIA TSH Kit on dried blood specimens collected by heelprick on filter paper. All infants with TSH values greater than 20 microU/ml were retested. If the results remained abnormally high, confirmatory testing was done by radioimmunoassay. All infants who were confirmed to be hypothyroid were referred to pediatric endocrinologists for initial management. The overall weighted incidence of congenital hypothyroidism obtained in this study was 0.000277 (95% CI; 0.000122 - 0.000432) or 1:3,610 which may be higher than that reported by most screening programs worldwide. The recall rate was 0.16%. The higher recall rate may be explained by early testing in a number of cases and by the possibility of iodine deficiency in some of the mothers. On the basis of the results of this study, we would recommend (1) screening on a greater number of infants to verify the incidence of CH and (2) establishing normal TSH values at different hours of life to improve our recall rate.

  19. Automated respiratory support in newborn infants. (United States)

    Claure, Nelson; Bancalari, Eduardo


    A considerable proportion of premature infants requires mechanical ventilatory support and supplemental oxygen. Due to their immaturity, exposure to these forms of respiratory support contributes to the development of lung injury, oxidative stress and abnormal retinal development. These conditions are associated with poor long-term respiratory and neurological outcome. Mechanically ventilated preterm infants present with frequent fluctuations in ventilation and gas exchange. Currently available ventilatory modes and manual adjustment to the ventilator or supplemental oxygen cannot effectively adapt to these recurrent fluctuations. Moreover, the respiratory support often exceeds the infant's real needs. Techniques that adapt the mechanical ventilatory support and supplemental oxygen to the changing needs of preterm infants are being developed in order to improve stability of gas exchange, to minimise respiratory support and to reduce personnel workload. This article describes the preliminary evidence on the application of these new techniques in preterm infants and animal models.

  4. Pharmacology of milrinone in neonates with persistent pulmonary hypertension of the newborn and suboptimal response to inhaled nitric oxide. (United States)

    McNamara, Patrick J; Shivananda, Sandesh P; Sahni, Mohit; Freeman, David; Taddio, Anna


    Persistent pulmonary hypertension of the newborn is a common problem with significant morbidity and mortality. Inhaled nitric oxide is the standard care, but up to 40% of neonates are nonresponders. Milrinone is a phosphodiesterase III inhibitor which increases the bioavailability of cyclic adenosine monophosphate and has been shown to improve pulmonary hemodynamics in animal experimental models. The primary objective was to investigate the pharmacological profile of milrinone in persistent pulmonary hypertension of the newborn. Secondary objectives were to delineate short-term outcomes and safety profile. An open label study of milrinone in neonates with persistent pulmonary hypertension of the newborn was conducted. Patients received an intravenous loading dose of milrinone (50 μg/kg) over 60 mins followed by a maintenance infusion (0.33-0.99 μg/kg/min) for 24-72 hrs. Physiologic indices of cardiorespiratory stability and details of cointerventions were recorded. Serial blood milrinone levels were collected after the bolus, following initiation of the maintenance infusion to determine steady state levels, and following discontinuation of the drug to determine clearance. Echocardiography was performed before and after (1, 12 hrs) milrinone initiation. Milrinone. Eleven neonates with a diagnosis of persistent pulmonary hypertension of the newborn who met eligibility criteria were studied. The median (SD) gestational age and weight at birth were 39.2 ± 1.3 wks and 3481 ± 603 g. The mean (± sd) half-life, total body clearance, volume of distribution, and steady state concentration of milrinone were 4.1 ± 1.1 hrs, 0.11 ± 0.01 L/kg/hr, 0.56 ± 0.19 L/kg, and 290.9 ± 77.7 ng/mL. The initiation of milrinone led to an improvement in PaO2 (p = 0.002) and a sustained reduction in FIO2 (p milrinone treatment. The pharmacokinetics of milrinone in persistent pulmonary hypertension of the newborn is consistent with published data. The administration of intravenous

  6. The increase of Lactobacillus species in the gut flora of newborn broiler chicks and ducks is associated with weight gain.

    Directory of Open Access Journals (Sweden)

    Emmanouil Angelakis

    Full Text Available BACKGROUND: A bacterial role in the obesity pandemic has been suspected based on the ingestion of probiotics that can modify the gut flora. The objective of our study was to determine if increased Lactobacillus sp. in the gut flora of newborn broiler chicks and ducks could result in weight gain increase. METHODOLOGY: Female broiler chicks (Gallus gallus domesticus and ducks (Anas platyrhynchos domestica were separated into one control and two experimental groups, and inoculated once or twice with 4x10(10Lactobacillus spp. per animal in PBS, or with PBS alone. Fecal samples were collected before and at 24 hours, 2, 4, 8, 16 and 30 days after the inoculation. DNA was extracted from the stools, and qPCR assays were performed on a MX3000 system for the detection and quantification of Lactobacillus sp., Bacteroidetes and Firmicutes, using a quantification plasmid. Animals were measured and sacrificed 60 days after the beginning of the experiment, and livers were collected and measured. PRINCIPAL FINDINGS: Chicks inoculated once and twice with Lactobacillus weighed 10.2% (p = 0.0162 and 13.5% (p = 0.0064 more than the control group animals, respectively. Similarly, ducks inoculated once and twice weighed 7.7% (p = 0.05 and 14% (p = 0.035 more than those in the control group, respectively. Liver mass was also significantly higher in inoculated animals compared to the control group. Inoculation with Lactobacillus sp. increased the DNA copies of Lactobacillus spp. and Firmicutes in the stools. Bacteroidetes remained stable, and only the second Lactobacillus sp. inoculation significantly decreased its population in chicks. The ratio of DNA copies of Firmicutes to those of Bacteroidetes increased to as much as 6,4 in chicks and 8,3 in ducks. CONCLUSIONS: Differences in the intestinal microbiota may precede weight increase, as we found that an increase of Lactobacillus sp. in newborn ducks and chicks preceded the development of weight gain.

  7. Platelet-activating factor synthesis and receptor-mediated signaling are downregulated in ovine newborn lungs: relevance in postnatal pulmonary adaptation and persistent pulmonary hypertension of the newborn. (United States)

    Renteria, L S; Cruz, E; Ibe, B O


    Platelet-activating factor (PAF) is a phospholipid with a wide range of biological activities. We studied PAF metabolism and PAF receptor (PAFR) signaling in perinatal ovine lungs to understand PAF's role in transition of the perinatal pulmonary hemodynamics and pathophysiology of persistent pulmonary hypertension of the newborn. We hypothesized that downregulation of PAF synthesis with upregulation of PAF catabolism by acetylhydrolase (PAF-Ah) in the newborn lung is needed for fetus-to-newborn pulmonary adaptation. Studies were conducted on fetal and newborn lamb pulmonary arteries (PA), veins (PV) and smooth muscle cells (SMC). PAF metabolism, PAFR binding and cell proliferation were studied by cell culture; gene expression was studied by qPCR. Fetal lungs synthesized 60% more PAF than newborn lungs. Compared with the fetal PVs and SMCs, PAF-Ah activity in newborn was 40-60% greater. PAF-Ah mRNA expression in newborn vessels was different from the expression by fetal PA. PAF-Ah gene clone activity confirmed deletion of hypoxia-sensitive site. PAFR mRNA expression by the PVs and SMC-PV of the fetus and newborn was greater than by corresponding PAs and SMC-PA. Q-PCR study of PAFR expression by the SMC-PV of both groups was greater than SMC-PA. Fetal SMCs bound more PAF than the newborn SMCs. PAFR antagonist, CV-3988, inhibited PAFR binding and DNA synthesis by the fetal SMCs, but augmented binding and DNA synthesis by newborn cells. We show different PAF-PAFR mediated effects in perinatal lungs, suggesting both transcriptional and translational regulation of PAF-Ah and PAFR expression in the perinatal lamb lungs. These indicate that the downregulation of PAF-mediated effects postnatally protects against persistent pulmonary hypertension of the newborn.

    Sandøe, Peter; Gamborg, Christian


    aimed at dealing with wild animals. McCulloch and Reiss argue that this could be remedied by means of a “mandatory application of formal and systematic Animal Welfare Impact Assessment (AWIA)”. Optimistically, they consider that an AWIA could help to resolve controversies involving wild animals. The aim...... is a welfare issue. Furthermore, we argue that AWIA is unlikely to prevent serious moral disagreements over how to weigh concerns about wild animals against priorities in human health, the health of domestic and farm animals, and biodiversity, but that it may nonetheless serve to limit harms imposed......Control of wild animals may give rise to controversy, as is seen in the case of badger control to manage TB in cattle in the UK. However, it is striking that concerns about the potential suffering of the affected animals themselves are often given little attention or completely ignored in policies...

    Pastorino, Giancarlo; Sergi, Paola; Mastrangelo, Massimo; Ravazzani, Paolo; Tognola, Gabriella; Parazzini, Marta; Mosca, Fabio; Pugni, Lorenza; Grandori, Ferdinando


    Since 1997 a newborn hearing screening programme has been implemented by the U.O. Neurologia-Neurofisiopatologia and Dipartimento di Neonatologia of the Istituti Clinici di Perfezionamento ICP in Milan for both babies with no risk and those at risk of hearing impairment. This programme was named the Milan Project. The protocol for no-risk babies consisted of three stages: in the first two stages, newborns were tested with transient click-evoked otoacoustic emissions (TEOAE), in the third one with conventional auditory brainstem responses (ABR). The first TEOAE test was performed by 36 h of age, before discharge, the second one after 15-30 d in case of referral, and the third one, by ABR, for those babies who failed the second TEOAE stage. Newborns at audiological risk were submitted to conventional ABR before the third month of corrected age. Some of this latter population was also submitted to the TEOAE test. The entire tested population (no-risk babies and newborns at audiological risk) consisted of 19 777 babies: 19 290 without risk ("no risk") and 487 at risk ("at risk"). During the course of the Milan Project, hearing impairment (ABR threshold equal to or greater than 40 dB nHL) was identified in 63 newborns (19 from the no-risk and 44 from the at-risk population), with a prevalence of 0.32%. Bilateral hearing impairment (BHI) was found in 33 newborns (10 from the no-risk and 23 from the at-risk population), corresponding to 0.17%. Among infants with bilateral hearing impairment, 30.3% had no risk factors. The prevalence of hearing impairment was determined on days 15-30 after birth. The results show that the implementation of a hospital-based, universal neonatal hearing screening programme for babies with and without audiological risk is feasible and effective. The effectiveness of the programme has increased as a function of the years since its inception, with a strong decrease in the referral rate. Further improvement is obtained if the TEOAE measurements

  10. Comparison of devices for newborn ventilation in the delivery room. (United States)

    Szyld, Edgardo; Aguilar, Adriana; Musante, Gabriel A; Vain, Nestor; Prudent, Luis; Fabres, Jorge; Carlo, Waldemar A


    To evaluate the effectiveness and safety of a T-piece resuscitator compared with a self-inflating bag for providing mask ventilation to newborns at birth. Newborns at ≥26 weeks gestational age receiving positive-pressure ventilation at birth were included in this multicenter cluster-randomized 2-period crossover trial. Positive-pressure ventilation was provided with either a self-inflating bag (self-inflating bag group) with or without a positive end-expiratory pressure valve or a T-piece with a positive end-expiratory pressure valve (T-piece group). Delivery room management followed American Academy of Pediatrics and International Liaison Committee on Resuscitation guidelines. The primary outcome was the proportion of newborns with heart rate (HR)≥100 bpm at 2 minutes after birth. A total of 1027 newborns were included. There was no statistically significant difference in the incidence of HR≥100 bpm at 2 minutes after birth between the T-piece and self-inflating bag groups: 94% (479 of 511) and 90% (466 of 516), respectively (OR, 0.65; 95% CI, 0.41-1.05; P=.08). A total of 86 newborns (17%) in the T-piece group and 134 newborns (26%) in the self-inflating bag group were intubated in the delivery room (OR, 0.58; 95% CI, 0.4-0.8; P=.002). The mean±SD maximum positive inspiratory pressure was 26±2 cm H2O in the T-piece group vs 28±5 cm H2O in the self-inflating bag group (P<.001). Air leaks, use of drugs/chest compressions, mortality, and days on mechanical ventilation did not differ significantly between groups. There was no difference between the T-piece resuscitator and a self-inflating bag in achieving an HR of ≥100 bpm at 2 minutes in newborns≥26 weeks gestational age resuscitated at birth. However, use of the T-piece decreased the intubation rate and the maximum pressures applied. Copyright © 2014 Elsevier Inc. All rights reserved.

  11. Thermal Dynamics in Newborn and Juvenile Models Cooled by Total Liquid Ventilation. (United States)

    Nadeau, Mathieu; Sage, Michael; Kohlhauer, Matthias; Vandamme, Jonathan; Mousseau, Julien; Robert, Raymond; Tissier, Renaud; Praud, Jean-Paul; Walti, Herve; Micheau, Philippe


    Total liquid ventilation (TLV) consists in filling the lungs with a perfluorocarbon (PFC) and using a liquid ventilator to ensure a tidal volume of oxygenated, CO 2 -free and temperature-controlled PFC. Having a much higher thermal capacity than air, liquid PFCs assume that the filled lungs become an efficient heat exchanger with pulmonary circulation. The objective of the present study was the development and validation of a parametric lumped thermal model of a subject in TLV. The lungs were modeled as one compartment in which the control volume varied as a function of the tidal volume. The heat transfer in the body was modeled as seven parallel compartments representing organs and tissues. The thermal model of the lungs and body was validated with two groups of lambs of different ages and weights (newborn and juvenile) undergoing an ultrafast mild therapeutic hypothermia induction by TLV. The model error on all animals yielded a small mean error of -0.1 ±0.4  (°)C for the femoral artery and 0.0 ±0.1   (°)C for the pulmonary artery. The resulting experimental validation attests that the model provided an accurate estimation of the systemic arterial temperature and the venous return temperature. This comprehensive thermal model of the lungs and body has the advantage of closely modeling the rapid thermal dynamics in TLV. The model can explain how the time to achieve mild hypothermia between newborn and juvenile lambs remained similar despite of highly different physiological and ventilatory parameters. The strength of the model is its strong relationship with the physiological parameters of the subjects, which suggests its suitability for projection to humans.

  12. Parents are interested in newborn genomic testing during the early postpartum period. (United States)

    Waisbren, Susan E; Bäck, Danielle K; Liu, Christina; Kalia, Sarah S; Ringer, Steven A; Holm, Ingrid A; Green, Robert C


    We surveyed parents to ascertain interest in newborn genomic testing and determine whether these queries would provoke refusal of conventional state-mandated newborn screening. After a brief genetics orientation, parents rated their interest in receiving genomic testing for their healthy newborn on a 5-point Likert scale and answered questions about demographics and health history. We used logistic regression to explore factors associated with interest in genomic testing and tracked any subsequent rejection of newborn screening. We queried 514 parents within 48 hours after birth while still in hospital (mean age (SD) 32.7 (6.4) years, 65.2% female, 61.2% white, 79.3% married). Parents reported being not at all (6.4%), a little (10.9%), somewhat (36.6%), very (28.0%), or extremely (18.1%) interested in genomic testing for their newborns. None refused state-mandated newborn screening. Married participants and those with health concerns about their infant were less interested in newborn genomic testing (P = 0.012 and P = 0.030, respectively). Degree of interest for mothers and fathers was discordant (at least two categories different) for 24.4% of couples. Interest in newborn genomic testing was high among parents of healthy newborns, and the majority of couples had similar levels of interest. Surveying parents about genomic sequencing did not prompt rejection of newborn screening.Genet Med 17 6, 501-504.

  13. Congenital Infantile Fibrosarcoma Causing Intestinal Perforation in a Newborn

    Directory of Open Access Journals (Sweden)

    Margarita Kaiser


    Full Text Available Congenital infantile fibrosarcoma (CIF is a rare malignant mesenchymal tumor and only 14 cases have been reported with gastrointestinal manifestation. We report about a female newborn delivered per emergency cesarean section at 34 weeks of gestation. Postnatally, she rapidly developed an acute abdomen and sonographic evidence of intestinal perforation requiring laparotomy on the first day of life. A perforated 2 × 3 cm sized spherical tumorous structure of the jejunum was identified. Due to unknown histopathology at this point and unclear resectional margins, she received a temporary ileostomy, which was closed two months later. Histopathology revealed a congenital intestinal fibrosarcoma without the characteristic ETV6-NTRK3 fusion transcript. In conclusion, this rare tumor must be considered as differential diagnosis of intestinal perforations in newborns.

  14. Measurements and monitoring of phototherapy in newborn jaundice

    International Nuclear Information System (INIS)

    Sisson, T.R.


    Hyperbilirubinemia in the newborn (neonatal jaundice) may cause irreversible brain damage if plasma concentrations of bilirubin exceed the number of binding sites on albumin and other blood components. Phototherapy or exchange transfusions to prevent the excessive rise in concentration of the pigment should be instituted in appropriate clinical situations. In phototherapy, the jaundiced infant is exposed to visible light containing the wavelength (about 450 nm) bilirubin will absorb. Because bilirubin is quite photolabile and will readily isomerize in vivo, it is rapidly converted to excretable forms. The effectiveness of this therapy, however, depends upon the maintenance of adequate radiant flux in the required wavelength. Energy output and spectral distributions of phototherapy lamps must be measured. The long-term effects of irradiation of newborn infants over several days are not yet known

    Majeed, R.; Memon, Y.; Majeed, F.


    To observe the clinical presentation of late haemorrhagic disease of the newborn (LHDNB), and clinical improvement after the administration of vitamin K/sub 1/. This is a prospective descriptive study. All the children older than seven days who presented with bleeding were admitted in pediatrics ward of Isra University Hyderabad from April 2006 to April 2007 were included. Data collection was done by means of detailed proforma. Analysis was done on SPSS version 11. Thirty five cases were included. Commonest site of bleeding was subcutaneous followed by oral and injection site. Mean age of late haemorrhagic disease of newborn was 109 days and minimum age of presentation was 28 days. Common clinical presentations were irritability, convulsions, poor reflexes and poor feeding. Mostly recovery was within 24 hours after vit K. Late HDN results in severe hemorrhage especially hemorrhage in the central nervous system. Administration of Vitamin K (1mg, 1M) at birth can present these severe complications. (author)

  16. Eye disorders in newborn infants (excluding retinopathy of prematurity). (United States)

    Wan, Michael J; VanderVeen, Deborah K


    A screening eye examination is an essential part of the newborn assessment. The detection of many ocular disorders in newborn infants can be achieved through careful observation of the infant's visual behaviour and the use of a direct ophthalmoscope to assess the ocular structures and check the red reflex. Early diagnosis and subspecialty referral can have a critical impact on the prognosis for many ocular conditions, including potentially blinding but treatable conditions such as congenital cataracts, life-threatening malignancies such as retinoblastoma and harbingers of disease elsewhere such as sporadic aniridia and its association with the development of Wilms tumour.

  17. [Prevalence of ankyloglossia in newborns in Asturias (Spain)]. (United States)

    González Jiménez, D; Costa Romero, M; Riaño Galán, I; González Martínez, M T; Rodríguez Pando, M C; Lobete Prieto, C


    The prevalence of ankyloglossia has been estimated at around 4% of live births. Its prevalence at national level is unknown. Multicenter, prospective observational study. Six hospitals in Asturias took part. All newborns were examined on Sundays, Tuesdays and Thursdays for 3 months. Coryllos and Hazelbaker criteria were used to diagnose ankyloglossia. The prevalence in the 667 newborns examined was 12.11% (95% CI: 9.58 to 14.64), of whom 62% were male. One in 4 children with ankyloglossia had a family history. According to Coryllos' classification, type II was the most common (54%). The prevalence of ankyloglossia in Asturias was 2 to t3 times higher than expected. The diagnostic criteria for ankyloglossia needs to be unified, and further studies are required to determine the association with breastfeeding difficulties and other health problems.

  18. A newborn with duodenal atresia and a gastric perforation

    Directory of Open Access Journals (Sweden)

    Akcora Bulent


    Full Text Available Congenital duodenal atresia complicated by gastric perforation (GP is a very rare and a very mortal condition. Only three newborns could be cured in the reported 13 cases. We report a successfully treated newborn with this complicated disease. A 2-day-old male was hospitalized with prediagnosis of duodenal obstruction. Twelve hours later, significant abdominal distention occurred promptly. At laparotomy, GP and preampullary duodenal atresia were detected. Gastrorrhaphy and duodenoduodenostomy were performed in the same operation. The patient was discharged on the 15th postoperative day. This complicated disease can be treated by early diagnosis and surgical intervention. We choose one-stage operation because of the clean peritoneal cavity. However, generalized peritonitis may require two-stage operation in delayed cases.

  19. The newborn oxygram: automated processing of transcutaneous oxygen data. (United States)

    Horbar, J D; Clark, J T; Lucey, J F


    Hypoxemic and hyperoxemic episodes are common in newborns with respiratory disorders. We have developed a microprocessor-based data system for use with transcutaneous oxygen (TcPO2) monitors in an attempt to quantitate these episodes. The amount of time spent by an infant in each of ten preset TcPO2 ranges can be automatically recorded. These data are referred to as the oxygram. Fourteen newborn infants were monitored for a total of 552 hours using this system. They spent a mean of 2.96% of the time with a TcPO2 less than or equal to 40 torr and 0.26% of the time with a TcPO2 greater than 100 torr. Representative oxygrams are presented. Clinical and research applications of the data system are discussed.

  20. Population newborn screening for inherited metabolic disease: current UK perspectives. (United States)

    Green, A; Pollitt, R J


    Some of the generally accepted criteria for screening programmes are inappropriate for newborn metabolic screening as they ignore the family dimension and the importance of timely genetic information. Uncritical application of such criteria creates special difficulties for screening by tandem mass spectrometry, which can detect a range diseases with widely different natural histories and responsiveness to treatment. Further difficulties arise from increasing demands for direct proof of the effects of screening on long-term morbidity and mortality. The randomized controlled trial is held to be the gold standard, but for ethical and practical reasons it will be impossible to achieve for such relatively rare diseases. This approach also oversimplifies the complex matrix of costs and benefits of newborn metabolic screening. A more workable approach could involve Bayesian synthesis, combining quantitative performance data from carefully designed prospective pilot studies of screening with existing experience of the natural history, diagnosis, and management of the individual disorders concerned.

  1. A laboratory cage for foster nursing newborn mice

    Directory of Open Access Journals (Sweden)

    S. Marques-de-Araújo


    Full Text Available We describe a cage to be used for foster nursing in order to guarantee that original mother's colostrum is not ingested by the newborn mice. A common (30.5 cm x 19.5 cm x 12.0 cm mouse cage was fitted with a wire net tray with a mesh (1 cm x 1 cm, which divides the cage into an upper and a lower compartment. Mice born to females placed in the upper compartment pass through the mesh and fall into the lower compartment, where another lactating female with one or two of its own pups are. Of a total of 28 newborn mice of C3H/He and Swiss strains, 23 were successfully fostered. Important observations are presented to show that this is a valuable alternative for foster studies without great suffering on the part of the female.

  2. Severe persistent pulmonary hypertension of the newborn and dysmorphic features in neonate with a deletion involving TWIST1 and PHF14: a case report. (United States)

    Schinagl, Carina; Melum, Guro Reinholt; Rødningen, Olaug Kristin; Bjørgo, Kathrine; Andresen, Jannicke Hanne


    Persistent pulmonary hypertension is a well-known disease of the newborn that in most cases responds well to treatment with nitric oxide and treatment of any underlying causes. Genetic causes of persistent pulmonary hypertension of the newborn are rare. The TWIST1 gene is involved in morphogenetics, and deletions are known to cause Saethre-Chotzen syndrome. Deletions of PHF14 have never been reported in neonates, but animal studies have shown a link between severe defects in lung development and deletions of this gene. There have not, to the best of our knowledge, been any publications of a link between the genes TWIST1 and PHF14 and persistent pulmonary hypertension of the newborn, making this a novel finding. We describe a white male neonate born at term to non-consanguineous white parents; he presented with dysmorphic features and a therapy-refractory persistent pulmonary hypertension. Array-based comparative genomic hybridization revealed the presence of a 14.7 Mb interstitial deletion on chromosome 7, encompassing the genes TWIST1 and PHF14. The TWIST1 gene can explain our patient's dysmorphic features. His severe persistent pulmonary hypertension has, however, not been described before in conjunction with the TWIST1 gene, but could be explained by involvement of PHF14, consistent with findings in animal experiments showing lethal respiratory failure with depletion of PHF14. These findings are novel and of importance for the clinical management and diagnostic workup of neonates with severe persistent pulmonary hypertension of the newborn and dysmorphic features.

  3. Screening for seemingly healthy newborns with congenital cytomegalovirus infection by quantitative real-time polymerase chain reaction using newborn urine: an observational study. (United States)

    Yamaguchi, Akira; Oh-Ishi, Tsutomu; Arai, Takashi; Sakata, Hideaki; Adachi, Nodoka; Asanuma, Satoshi; Oguma, Eiji; Kimoto, Hirofumi; Matsumoto, Jiro; Fujita, Hidetoshi; Uesato, Tadashi; Fujita, Jutaro; Shirato, Ken; Ohno, Hideki; Kizaki, Takako


    Approximately 8-10% of newborns with asymptomatic congenital cytomegalovirus (cCMV) infection develop sensorineural hearing loss (SNHL). However, the relationship between CMV load, SNHL and central nervous system (CNS) damage in cCMV infection remains unclear. This study aimed to examine the relationship between urinary CMV load, SNHL and CNS damage in newborns with cCMV infection. The study included 23 368 newborns from two maternity hospitals in Saitama Prefecture, Japan. Urine screening for cCMV infection (quantitative real-time PCR) and newborn hearing screening (automated auditory brainstem response (AABR) testing) were conducted within 5 days of birth to examine the incidence of cCMV infection and SNHL, respectively. CNS damage was assessed by MRI of cCMV-infected newborns. The incidence of cCMV infection was 60/23 368 (0.257%; 95% CI 0.192% to 0.322%). The geometric mean urinary CMV DNA copy number in newborns with cCMV was 1.79×10 6 copies/mL (95% CI 7.97×10 5 to 4.02×10 6 ). AABR testing revealed abnormalities in 171 of the 22 229 (0.769%) newborns whose parents approved hearing screening. Of these 171 newborns, 22 had SNHL (12.9%), and 5 of these 22 were infected with cCMV (22.7%). Newborns with both cCMV and SNHL had a higher urinary CMV DNA copy number than newborns with cCMV without SNHL (p=0.036). MRI revealed CNS damage, including white matter abnormalities, in 83.0% of newborns with cCMV. Moreover, newborns with CNS damage had a significantly greater urinary CMV load than newborns without CNS damage (p=0.013). We determined the incidence of cCMV infection and urinary CMV DNA copy number in seemingly healthy newborns from two hospitals in Saitama Prefecture. SNHL and CNS damage were associated with urinary CMV DNA copy number. Quantification of urinary CMV load may effectively predict the incidence of late-onset SNHL and neurodevelopmental disorders.

  4. Extremely high concentration of folates in premature newborns. (United States)

    Zikavska, T; Brucknerova, I


    Extremely high concentration of folates in premature newborns: case reports. Folates are a group of water soluble compounds, which are important for metabolic processes in human body. These are important during periods of rapid cell growth. The most accurate indicator of long-term folate level status in the body is the determination of red blood cell (RBC) folate concentrations. The optimal level of RBC folate is not known in neonatal period. Authors discuss the reasons for extremely high level of RBC folate concentrations. In our work we present the cases of two premature newborns with extremely high level of RBC folate concentrations, which were analyzed immunochemically on the first day of life and after six weeks of life. In both cases we measured RBC folate concentrations on the 1st day of life. After 6 weeks we found extremely high RBC folate concentration level (5516.67 ng/ml) in the first case after RBC transfusions. In second case after two months of life the RBC folate concentration level was doubled (2335.1 ng/ml) until 24 hours after RBC transfusion compared to levels after birth. The normal range of RBC folate values vary in newborns. The upper limit of daily dose of folic acid in pregnancy and neonatal period is not known. On the other hand it is an easily excreted water-soluble vitamin but in premature newborn it can lead to the disruption of metabolic balance and slow its degradation. Some factors can have an impact on RBC folate concentration. Blood transfusion can be one of the main influences on RBC folate concentration. To clarify these mechanisms further studies are required (Ref. 29).

  5. A clinical prediction rule for histological chorioamnionitis in preterm newborns.

    Directory of Open Access Journals (Sweden)

    Jasper V Been

    Full Text Available BACKGROUND: Histological chorioamnionitis (HC is an intrauterine inflammatory process highly associated with preterm birth and adverse neonatal outcome. HC is often clinically silent and diagnosed postnatally by placental histology. Earlier identification could facilitate treatment individualisation to improve outcome in preterm newborns. AIM: Develop a clinical prediction rule at birth for HC and HC with fetal involvement (HCF in preterm newborns. METHODS: Clinical data and placental pathology were obtained from singleton preterm newborns (gestational age ≤ 32.0 weeks born at Erasmus UMC Rotterdam from 2001 to 2003 (derivation cohort; n = 216 or Máxima MC Veldhoven from 2009 to 2010 (validation cohort; n = 206. HC and HCF prediction rules were developed with preference for high sensitivity using clinical variables available at birth. RESULTS: HC and HCF were present in 39% and 24% in the derivation cohort and in 44% and 22% in the validation cohort, respectively. HC was predicted with 87% accuracy, yielding an area under ROC curve of 0.95 (95%CI = 0.92-0.98, a positive predictive value of 80% (95%CI = 74-84%, and a negative predictive value of 93% (95%CI = 88-96%. Corresponding figures for HCF were: accuracy 83%, area under ROC curve 0.92 (95%CI = 0.88-0.96, positive predictive value 59% (95%CI = 52-62%, and negative predictive value 97% (95%CI = 93-99%. External validation expectedly resulted in some loss of test performance, preferentially affecting positive predictive rather than negative predictive values. CONCLUSION: Using a clinical prediction rule composed of clinical variables available at birth, HC and HCF could be predicted with good test characteristics in preterm newborns. Further studies should evaluate the clinical value of these rules to guide early treatment individualisation.

  6. Postpartum follow-up: can psychosocial support reduce newborn readmissions? (United States)

    Barilla, Dora; Marshak, Helen Hopp; Anderson, S Eric; Hopp, Joyce W


    To determine whether there was a relationship between postpartum psychosocial support from healthcare providers and the rate of normal newborn readmissions (NNRs), and whether there was a cost benefit to justify an intervention. Data were abstracted for all normal newborn births from 1999 to 2006 (N = 14,786) at a community hospital in southern California at three different time periods: (1) at baseline prior to any intervention (1999-2000), (2) the 4 years during the comprehensive psychosocial support intervention (2001-2004), and (3) the 2 years during a limited psychosocial support intervention (2004-2006). A cost-benefit analysis was performed to analyze whether the financial benefits from the intervention matched or exceeded the costs for NNRs. There was a significantly lower readmission rate of 1.0% (p = < .001) during the comprehensive intervention time period compared to baseline (2.3%) or to the limited intervention time period (2.3%). Although there was no significant difference in the average cost per newborn readmitted across the three study time periods, during the comprehensive intervention time period the average costs of a NNR were significantly lower ($4,180, p = .041) for the intervention group compared to those who received no intervention ($5,338). There was a cost benefit of 513,540 dollars due to fewer readmissions during the comprehensive time period, but it did not exceed the cost of the intervention. Providing comprehensive follow-up for new mothers in the postpartum period can reduce NNRs, thus lowering the average newborn readmission costs for those who receive psychosocial support. Followup for new mothers should be an accepted norm rather than the exception in postpartum care, but NNRs should not be considered the sole outcome in such programs.

  7. Newborn Screening in the Era of Precision Medicine. (United States)

    Yang, Lan; Chen, Jiajia; Shen, Bairong


    As newborn screening success stories gained general confirmation during the past 50 years, scientists quickly discovered diagnostic tests for a host of genetic disorders that could be treated at birth. Outstanding progress in sequencing technologies over the last two decades has made it possible to comprehensively profile newborn screening (NBS) and identify clinically relevant genomic alterations. With the rapid developments in whole-genome sequencing (WGS) and whole-exome sequencing (WES) recently, we can detect newborns at the genomic level and be able to direct the appropriate diagnosis to the different individuals at the appropriate time, which is also encompassed in the concept of precision medicine. Besides, we can develop novel interventions directed at the molecular characteristics of genetic diseases in newborns. The implementation of genomics in NBS programs would provide an effective premise for the identification of the majority of genetic aberrations and primarily help in accurate guidance in treatment and better prediction. However, there are some debate correlated with the widespread application of genome sequencing in NBS due to some major concerns such as clinical analysis, result interpretation, storage of sequencing data, and communication of clinically relevant mutations to pediatricians and parents, along with the ethical, legal, and social implications (so-called ELSI). This review is focused on these critical issues and concerns about the expanding role of genomics in NBS for precision medicine. If WGS or WES is to be incorporated into NBS practice, considerations about these challenges should be carefully regarded and tackled properly to adapt the requirement of genome sequencing in the era of precision medicine.

  8. Aortic mass in a newborn infant with respiratory distress

    Directory of Open Access Journals (Sweden)

    Michelle J. Vaz


    Full Text Available Thrombotic disease is rare in neonates. Many of the cases reported in literature are attributed to the placement of central catheters. We report on a case of aortic thrombosis in a newborn infant with significant respiratory distress due to meconium aspiration, necessitating intubation and placement of central catheters. Due to the location and size of the thrombus in our case, various subspecialties were involved, which ultimately guided therapy to anti-coagulate the patient.

  9. Hemolytic disease of the newborn- anti c antibody induced hemolysis. (United States)

    Murki, Srinivas; Kandraju, Hemasree; Devi, Surekha A


    Hemolytic disease in the newborn, as a cause of early jaundice, is not uncommon. This is mostly due to Rh (D), ABO incompatibility and rarely due to other minor blood group incompatibility. The authors report two cases of Rh anti c isoimmunization presenting as significant early neonatal jaundice within the 20 h of life. Both the babies were treated with intensive phototherapy. One baby underwent exchange transfusion and the other required packed cell transfusion for anemia.

    Maternal antibody-mediated fetal red blood cell destruction secondary to non-D Rhesus (Rh) antibodies is a significant cause of hemolytic disease of the newborn (HDN). Here, we report a rare case of severe HDN associated with maternal antibody to Rh e. In addition to severe anemia, the infant developed thrombocytopenia, conjugated hyperbilirubinemia and cholelithiasis. Resolution of the infant's cholelithiasis occurred following treatment with ursodeoxycholic acid.

  11. Positive pressure ventilation and cranial volume in newborn infants.


    Milligan, D W


    The relationship between changes in airways pressure, pleural pressure, and cranial volume was studied in a group of sick newborn infants requiring ventilatory assistance. Cranial volume increased appreciably only when lung compliance was such that more than 20% of the applied airways pressure was transmitted to the pleural space, or if the absolute pleural pressure was greater than 4 cmH2O above atmospheric pressure. The findings stress the need for more-critical monitoring during periods of...

    Introduction The population of children born prematurely has increased in line with improving the quality of perinatal care. It is essential to ensure to these children a healthy development. Objective We evaluate the neuromotor development of a group of preterm infants regularly assisted by a physiotherapy service in comparison to full-term newborns, checking, so the impact of the service. Materials and methods We randomly assigned preterm and full-term infants that formed two distinct group...

  14. Bilateral scrotal abscesses caused by Klebsiella pneumoniae in a newborn. (United States)

    Di Renzo, Dacia; Pappalepore, Nicola; Colangelo, Maurizia; Chiesa, Pierluigi Lelli


    The management of acute scrotal swelling can be challenging in neonatal age, with scrotal infections being great mimickers of testicular torsion. Only a few unilateral cases of scrotal abscess have been previously reported, mostly caused by Staphylococcus and Salmonella. We describe the case of a newborn who developed bilateral scrotal abscesses caused by Klebsiella pneumoniae and discuss the rarity of the case, regarding both the bilaterality and the pathogen, never reported before.

    Establishing the correct diagnosis in newborns presenting with blisters and erosions is not always a straightforward process. Many different disease entities including acquired (i.e., infectious, immunobullous, traumatic) and inherited disorders have to be taken into consideration. Similarities in clinical appearance, colonization and/or superinfections of preexisting skin lesions, as well as the absence of late changes in the neonate often pose significant diagnostic challenges. In this pape...

  16. Selective nontreatment of handicapped newborns: a critical essay. (United States)

    Kohrman, A F


    The neonatal intensive care unit is the site of some of the most dramatic technology, complex decision-making and costly activity in the current range of medical institutions. Thus, the decisions made there are particularly visible, and of concern to a society which has increasingly scrutinized and challenged medical practices. Questions of marginal utility and cost-benefit relationships are becoming increasingly prominent. These concerns are heightened by the social and political tensions over issues of the time of initiation of life, quality of life, and assurances of equity for those less well off or handicapped from birth. Robert Weir's book, Selective Nontreatment of Handicapped Newborns, successfully summarizes the current dilemmas and identifies areas of uncertainty and lack of knowledge which cloud the decision-making processes. The book reviews the positions of the major protagonists of the last several years; inevitably, their positions will undergo continuous evolution in response to new data and vigorous political and public policy activity. Weir appropriately identifies the difficulty in arriving at an accurate prognosis as an important and prominent problem in decision-making about defective newborns. The population of surviving, compromised newborns is relatively unfamiliar and their problems remain largely unstudied. Weir's discussion of the desirability of the establishment of Infant Care Review Committees in those institutions which care for defective and handicapped newborns thoughtfully concludes that such committees are, on the balance, desirable. As experience accumulates with Infant Care Review Committees, they should serve the positive purpose of generating open discussion of legitimate disagreements. These committees will provide a forum in which decision-makers can disclose uncertainty, consider alternatives, and receive counsel.(ABSTRACT TRUNCATED AT 250 WORDS)

    Sensory receptors are distributed throughout the oral cavity, pharynx, and larynx. Laryngeal sensitivity is crucial for maintaining safe swallowing, thus avoiding silent aspiration. Morphologic description of different receptor types present in larynx vary because of the study of many different species, from mouse to humans. The most commonly sensory structures described in laryngeal mucosa are free nerve endings, taste buds, muscle spindles, glomerular and corpuscular receptors. This study aimed at describing the morphology and the distribution of nerve endings in premature newborn glottic region. Transversal serial frozen sections of the whole vocal folds of three newborns were analyzed using an immuno-histochemical process with a pan-neuronal marker anti-protein gene product 9.5 (PGP 9.5). Imaging was done using a confocal laser microscope. Nerve fiber density in vocal cord was calculated using panoramic images in software Morphometric Analysis System v1.0. Some sensory structures, i.e. glomerular endings and intraepithelial free nerve endings were found in the vocal cord mucosa. Muscle spindles, complex nerve endings (Meissner-like, spherical, rectangular and growing) spiral-wharves nerve structures were identified in larynx intrinsic muscles. Nervous total mean density in vocal cord was similar in the three newborns, although they had different gestational age. The mean nerve fiber density was higher in the posterior region than anterior region of vocal cord. The present results demonstrate the occurrence of different morphotypes of sensory corpuscles and nerve endings premature newborn glottic region and provide information on their sensory systems.

  18. Animals as disgust elicitors

    DEFF Research Database (Denmark)

    Kasperbauer, Tyler Joshua


    This paper attempts to explain how and why nonhuman animals elicit disgust in human beings. I argue that animals elicit disgust in two ways. One is by triggering disease–protection mechanisms, and the other is by eliciting mortality salience, or thoughts of death. I discuss how these two types...... of disgust operate and defend their conceptual and theoretical coherence against common objections. I also outline an explanatory challenge for disgust researchers. Both types of disgust indicate that a wide variety of animals produce aversive and avoidant reactions in human beings. This seems somewhat odd......, given the prominence of animals in human lives. The challenge, then, is explaining how humans cope with the presence of animals. I propose, as a hypothesis for further exploration, that we cope with animals, and our disgust responses to them, by attributing mental states that mark them as inferior...

  19. Draught animals and welfare. (United States)

    Ramaswamy, N S


    In fifty developing countries, which contain half of the total human population of the world, there is a heavy dependence on draught animals as an energy source. These animals are used for agriculture operations in 52% of cultivated areas of the world, as well as for hauling 25 million carts. This situation is likely to continue for at least another fifty years. The work performed annually by these draught animals would require 20 million tons of petroleum, valued at US$6 billion, if it were performed by motorized vehicles. The poor working conditions of these animals often adversely affect their productivity. The application of improved technology and better management (i.e. through better feed and health services, and improved design of agricultural implements and carts) could considerably improve the welfare of these animals. Improved systems would generate sufficient benefits for the economy to justify the required investment. High priority should therefore be given to draught animal power in the economic development agenda.

  20. Umbilical cord blood glucose levels in full-term newborns

    Directory of Open Access Journals (Sweden)

    A. L. Karpova


    Full Text Available The purpose of the investigation was to determine the umbilical cord venous blood level of glucose in full-term newborns and its relationship to the mode of delivery. The investigation included 102 full-term newborn infants, including 33 and 69 babies born via cesar-ean and vaginal delivery, respectively. Umbilical cord serum glucose levels were determined by the glucose oxidase test using a Sap-phire-400 biochemical analyzer. In healthy full-term newborns, the mean umbilical cord blood glucose levels were 4,29±0,88 mmol/1 (minimum, 2,9 mmol/1 and maximum, 5,9 mmol/1. In the babies born via cesarean delivery, the umbilical cord blood concentration of glucose was ascertained to be significantly lower than in those born vaginally (3,84+0,71 mmol/1 versus 4,51+0,87 mmol/1; /><0,0001. Abdominal delivery can be apparently considered to be a risk factor for hypoglycemia in neonatal infants.

  1. Holocarboxylase synthetase deficiency pre and post newborn screening

    Directory of Open Access Journals (Sweden)

    Taraka R. Donti


    Full Text Available Holocarboxylase synthetase deficiency is an autosomal recessive disorder of biotin metabolism resulting in multiple carboxylase deficiency. The typical presentation described in the medical literature is of neonatal onset within hours to weeks of birth with emesis, hypotonia, lethargy, seizures, metabolic ketolactic acidosis, hyperammonemia, developmental delay, skin rash and alopecia. The condition is screened for by newborn screening (NBS tandem mass spectroscopy by elevated hydroxypentanoylcarnitine on dried blood spots. Urine organic acid profile may demonstrate elevated lactic, 3-OH isovaleric, 3-OH propionic, 3-MCC, methylcitric acids, and tiglylglycine consistent with loss of function of the above carboxylases. Here we describe a cohort of patients, 2 diagnosed pre-NBS and 3 post-NBS with broad differences in initial presentation and phenotype. In addition, prior to the advent of NBS, there are isolated reports of late-onset holocarboxylase synthetase deficiency in the medical literature, which describe patients diagnosed between 1 and 8 years of life, however to our knowledge there are no reports of late-onset HCLS being missed by NBS. Also we report two cases, each with novel pathogenic variants HCLS, diagnosed at age 3 years and 21 months respectively. The first patient had a normal newborn screen whilst the second had an abnormal newborn screen but was misdiagnosed as 3-methylcrotonylcarboxylase (3-MCC deficiency and subsequently lost to follow-up until they presented again with severe metabolic acidosis.

  2. Therapeutic touch: influence on vital signs of newborns. (United States)

    Ramada, Nadia Christina Oliveira; Almeida, Fabiane de Amorim; Cunha, Mariana Lucas da Rocha


    To compare vital signs before and after the therapeutic touch observed in hospitalized newborns in neonatal intensive care unit. This was a quasi-experimental study performed at a neonatal intensive care unit of a municipal hospital, in the city of São Paulo (SP), Brazil. The sample included 40 newborns submitted to the therapeutic touch after a painful procedure. We evaluated the vital signs, such as heart and respiratory rates, temperature and pain intensity, before and after the therapeutic touch. The majority of newborns were male (n=28; 70%), pre-term (n=19; 52%) and born from vaginal delivery (n=27; 67%). Respiratory distress was the main reason for hospital admission (n=16; 40%). There was a drop in all vital signs after therapeutic touch, particularly in pain score, which had a considerable reduction in the mean values, from 3.37 (SD=1.31) to 0 (SD=0.0). All differences found were statistically significant by the Wilcoxon test (ptouch promotes relaxation of the baby, favoring reduction in vital signs and, consequently in the basal metabolism rate.

  3. The art, science and philosophy of newborn care. (United States)

    Singh, Meharban


    Neonates truly constitute the foundation of a nation and no sensible government can afford to neglect their needs and rights. In the last 50 y, technology has revolutionized neonatology and we have moved from an exceedingly passive or "hands-off" philosophy to an extremely aggressive or mechanistic approach. Deaths during first 28 d of life account for over 60 % of all infant deaths and 40 % of all deaths of under-5 children. If we have to further reduce infant mortality rate in our country we must focus our strategies to improve health and survival of newborn babies. There should be equitable distribution of resources for the care of mothers and babies in the community and establishment of high-tech newborn care facilities. In 21st century, we must delink and sever our dependence on traditional birth attendants or dais and develop necessary infrastructure and facilities to ensure that every pregnant woman is provided with essential antenatal care and all deliveries take place at health care facilities and they are conducted by trained health care professionals. In the best pediatric tradition, there is a need for greater focus on preventive rather than curative health care strategies because a large number of neonatal deaths occur due to potentially preventable disorders like birth asphyxia, hypothermia, hypoglycemia and infections. The art and science of neonatology should be integrated and we should follow a "middle path" and strike a balance between art and technology in the care of newborns.

    Directory of Open Access Journals (Sweden)

    Hüseyin Altunhan


    Full Text Available Classical galactosemia is a rarely seen carbohydrate metabolismdisorder. The frequency of sepsis significantlyincreases in patients with galactosemia. The most commonagent causing sepsis is E. coli. Sepsis due to fungusin patients with galactosemia is rarely reported. Candidais an important cause of sepsis in newborn intensive careunits especially in newborns with underlying risk factorssuch as prematurity and low birth weight. Although themost common etiologic agent of sepsis is E. coli in caseswith galactosemia, it should be kept in mind that candidamay also be causative agent of sepsis and meningitis inthese patients even though there is no underlying risk factor.Also the clinical and laboratory findings of candidiasismay be obscure. For this reason, especially in newborncandida meningitis, the index of suspicion should be kepthigh for early diagnosis and treatment. In such patientscerebrospinal fluid analysis, culture and brain imagingshould be done necessarily, because early diagnosis andtreatment will be life saving. In this article we reported agalactosemia case with the diagnosis of meningitis andCandida albicans grown in his blood culture derived onthe fourth day of admission to clinic.Key words: Candida albicans, galactosemia, meningitis,newborn, sepsis

  6. Prevalence of exclusive breastfeeding in the healthy newborn. (United States)

    Mazo-Tomé, Pedro Luis Del; Suárez-Rodríguez, Marta


    The best nourishment for infants during the first 6 months of life is exclusive breastfeeding. It is recommended along with other food to complement the diet until the child is 2 years old, as long as the mother and the child are willing to continue with it. The objectives of this study were to determine he exclusive breastfeeding rate in full term newborns at hospital discharge and 15 days later and to analyze the factors that positively affect the exclusive breastfeeding. A prospective study was conducted in which a sample of postpartum women with full term newborns was recruited during hospital admission. Different variables were compiled and two interviews were made to determine the kind of feeding they were giving their children and if it was maintained at 15 days of birth. Exclusive breastfeeding rate at hospital discharge is much lower than recommended. It significantly decreases at 15 days of birth, increasing artificial feeding. It seems that having a vaginal birth, no complications giving birth, providing early breastfeeding and skin-to-skin contact in the delivery room are predisposing factors necessary to establish a good breastfeeding at hospital discharge. Despite the efforts of professionals, the percentage of newborns with exclusive breastfeeding at birth is not enough for the current recommendations. Copyright: © 2018 Permanyer.

  7. Suction is kid's play: extremely fast suction in newborn seahorses (United States)

    Van Wassenbergh, Sam; Roos, Gert; Genbrugge, Annelies; Leysen, Heleen; Aerts, Peter; Adriaens, Dominique; Herrel, Anthony


    Ongoing anatomical development typically results in a gradual maturation of the feeding movements from larval to adult fishes. Adult seahorses are known to capture prey by rotating their long-snouted head extremely quickly towards prey, followed by powerful suction. This type of suction is powered by elastic recoil and requires very precise coordination of the movements of the associated feeding structures, making it an all-or-none phenomenon. Here, we show that newborn Hippocampus reidi are able to successfully feed using an extremely rapid and powerful snout rotation combined with a high-volume suction, surpassing that observed in adult seahorses. An inverse dynamic analysis shows that an elastic recoil mechanism is also used to power head rotation in newborn H. reidi. This illustrates how extreme levels of performance in highly complex musculoskeletal systems can be present at birth given a delayed birth and rapid development of functionally important structures. The fact that the head skeleton of newborn seahorses is still largely cartilaginous may not be problematic because the hydrodynamic stress on the rotating snout appeared considerably lower than in adult syngnathids.

  8. Antibiotic Therapy for Very Low Birth Weigh Newborns in NICU (United States)

    Afjeh, Seyyed-Abolfazl; Sabzehei, Mohammad-Kazem; Fahimzad, Seyyed-Ali-Reza; Shiva, Farideh; Shamshiri, Ahmad-Reza; Esmaili, Fatemeh


    Background Prolonged empiric antibiotics therapy in neonates results in several adverse consequences including widespread antibiotic resistance, late onset sepsis (LOS), necrotizing enterocolitis (NEC), prolonged hospital course (HC) and increase in mortality rates. Objectives To assess the risk factors and the outcome of prolonged empiric antibiotic therapy in very low birth weight (VLBW) newborns. Materials and Methods Prospective study in VLBW neonates admitted to NICU and survived > 2 W, from July 2011 - June 2012. All relevant perinatal and postnatal data including duration of antibiotics therapy (Group I 2W) and outcome up to the time of discharge or death were documented and compared. Results Out of 145 newborns included in the study, 62 were in group I, and 83 in Group II. Average duration of antibiotic therapy was 14 days (range 3 - 62 days); duration in Group I and Group II was 10 ± 2.3 vs 25.5 ± 10.5 days. Hospital stay was 22.3 ± 11.5 vs 44.3 ± 14.7 days, respectively. Multiple regression analysis revealed following risk factors as significant for prolonged empiric antibiotic therapy: VLBW especially stage II, 12 (8.3%) newborns died. Infant mortality alone and with LOS/NEC was higher in group II as compared to group I (P < 0.002 and < 0.001 respectively). Conclusions Prolonged empiric antibiotic therapy caused increasing rates of LOS, NEC, HC and infant mortality. PMID:27307961

  9. Oxidative stress in resuscitation and in ventilation of newborns. (United States)

    Gitto, E; Pellegrino, S; D'Arrigo, S; Barberi, I; Reiter, R J


    The lungs of newborns are especially prone to oxidative damage induced by both reactive oxygen and reactive nitrogen species. Yet, these infants are often 1) exposed to high oxygen concentrations, 2) have infections or inflammation, 3) have reduced antioxidant defense, and 4) have high free iron levels which enhance toxic radical generation. Oxidative stress has been postulated to be implicated in several newborn conditions with the phrase "oxygen radical diseases of neonatology" having been coined. There is, however, reason to believe that oxidative stress is increased more when resuscitation is performed with pure oxygen compared with ambient air and that the most effective ventilatory strategy is the avoidance of mechanical ventilation with the use of nasopharyngeal continuous positive airway pressure whenever possible. Multiple ventilation strategies have been attempted to reduce injury and improve outcomes in newborn infants. In this review, the authors summarise the scientific evidence concerning oxidative stress as it relates to resuscitation in the delivery room and to the various modalities of ventilation.

  10. Genetic contribution to patent ductus arteriosus in the premature newborn. (United States)

    Bhandari, Vineet; Zhou, Gongfu; Bizzarro, Matthew J; Buhimschi, Catalin; Hussain, Naveed; Gruen, Jeffrey R; Zhang, Heping


    The most common congenital heart disease in the newborn population, patent ductus arteriosus, accounts for significant morbidity in preterm newborns. In addition to prematurity and environmental factors, we hypothesized that genetic factors play a significant role in this condition. The objective of this study was to quantify the contribution of genetic factors to the variance in liability for patent ductus arteriosus in premature newborns. A retrospective study (1991-2006) from 2 centers was performed by using zygosity data from premature twins born at Patent ductus arteriosus was diagnosed by echocardiography at each center. Mixed-effects logistic regression was used to assess the effect of specific covariates. Latent variable probit modeling was then performed to estimate the heritability of patent ductus arteriosus, and mixed-effects probit modeling was used to quantify the genetic component. We obtained data from 333 dizygotic twin pairs and 99 monozygotic twin pairs from 2 centers (Yale University and University of Connecticut). Data on chorioamnionitis, antenatal steroids, gestational age, body weight, gender, respiratory distress syndrome, patent ductus arteriosus, necrotizing enterocolitis, oxygen supplementation, and bronchopulmonary dysplasia were comparable between monozygotic and dizygotic twins. We found that gestational age, respiratory distress syndrome, and institution were significant covariates for patent ductus arteriosus. After controlling for specific covariates, genetic factors or the shared environment accounted for 76.1% of the variance in liability for patent ductus arteriosus. Preterm patent ductus arteriosus is highly familial (contributed to by genetic and environmental factors), with the effect being mainly environmental, after controlling for known confounders.

  11. [Aftercare of newborn infants in a patient hotel]. (United States)

    Lindgren, C


    Postnatal care of the healthy term newborn and the mother has, in modern times, taken place in the hospital setting. As a result of tightened hospital budgets as well as maternal preferences the duration of hospital stay has successively been shortened. Most women in Scandinavia today leave the hospital within four days after delivery. Postnatal care in a hotel like setting has emerged as an alternative to the well-baby nursery unless medical conditions makes this option inappropriate. To evaluate the safety of postnatal care a study was undertaken to investigate whether correct criteria were being used for referral of the newborn to the hotel. We also wanted to document the duration of stay, unexpected medical complications, and weight development of the infants. Data from 865 infants were used for analysis. Ten (1.1%) newborns had to be readmitted to the hospital due to medical complications. 488 (56%) of the mothers went home within 96 hours, and only 23 (2.6%) stayed more than 120 hours. The weight of the infants reached a nadir on the fourth day post partum (-5.2% of birth weight). The patient hotel is a medically safe alternative to the traditional well-baby nursery, provided that appropriate criteria for referral are used.

  12. Advanced neuroimaging techniques for the term newborn with encephalopathy. (United States)

    Chau, Vann; Poskitt, Kenneth John; Miller, Steven Paul


    Neonatal encephalopathy is associated with a high risk of morbidity and mortality in the neonatal period and of long-term neurodevelopmental disability in survivors. Advanced magnetic resonance techniques now play a major role in the clinical care of newborns with encephalopathy and in research addressing this important condition. From conventional magnetic resonance imaging, typical patterns of injury have been defined in neonatal encephalopathy. When applied in contemporary cohorts of newborns with encephalopathy, the patterns of brain injury on magnetic resonance imaging distinguish risk factors, clinical presentation, and risk of abnormal outcome. Advanced magnetic resonance techniques such as magnetic resonance spectroscopy, diffusion-weighted imaging, and diffusion tensor imaging provide novel perspectives on neonatal brain metabolism, microstructure, and connectivity. With the application of these imaging tools, it is increasingly apparent that brain injury commonly occurs at or near the time of birth and evolves over the first weeks of life. These observations have complemented findings from trials of emerging strategies of brain protection, such as hypothermia. Application of these advanced magnetic resonance techniques may enable the earliest possible identification of newborns at risk of neurodevelopmental impairment, thereby ensuring appropriate follow-up with rehabilitation and psychoeducational resources.

  13. [Early discharge of newborns: what problems should we anticipate?]. (United States)

    Straczek, H; Vieux, R; Hubert, C; Miton, A; Hascoet, J-M


    Following Nordic and Anglo-Saxon countries, France is directing towards an early discharge policy from maternity hospitals. French National Authority for Health has published recommendations focusing on the importance to highlight the dangers of such a policy so as to be able to anticipate them. To describe the complications diagnosed in the newborn infants from day 2 to the current hospital's discharge (noteworthy, if infants are discharged early, these complications may occur at home) to determine predictive factors and to validate those proposed by the French National Authority for Health. Prospective study conducted in the maternity ward of Nancy's level III facility, from January 6th to May 6th 2005. Nine hundred and three newborn infants were included. Forty-two (4.6%) presented with complications diagnosed from day 2 to hospital's discharge, among which 4 required urgent neonatal care. The most frequent complication was hyperbilirubinemia: 23 newborns were treated with phototherapy between day 2 and day 10. Statistically significant risk factors of hyperbilirubinemia after day 2 in multivariate analysis were instrumental vaginal delivery (OR=2.94; CI 95% [1.04-8.34]) and jaundice before day 2 (OR=7.39; CI 95% [2.66-20.55]). According to the French National Authority for Health's policy, 33 among 42 infants presenting with a complication would have been withdrawn from an early discharge program. In our population, French National Authority for Health's recommendations were relevant to guide an early discharge project.

  14. [The newborn infant of a mother with tuberculosis]. (United States)

    Pedicino, R; Bressan, K; Bedetta, M


    TBC is a major infectious emergency in the world. OMS suggest that there are 8 millions of affected every year and 2 millions of deaths. Italy is considered a country with low prevalence, but the increase of the immigration from Africa Asia and Est Europa (country with high risk) imposes attention to the problem. The delivery is a critical moment to investigate people at risk of disease. The infection of the newborn can happen intrauterine or in the expulsive period, but is possible also at home, from somebody affected by an active pulmonary disease. Diagnosis in the newborn is not easy for the aspecificity of clinical signs and for the frequent initial negativeness of Mantoux test. Culture of placenta, gastric aspirate, tracheal secretions, urine would be requested, cerebrospinal fluid if necessary. Neonatal disease needs therapy with isoniazide, rifampicine, pirazinamide and, or ethambutol, or streptomycin. Profilaxis of a newborn from a woman affected by an active form of tuberculosis or living with people affected by an active pulmonary form consists in giving isoniazide until diagnostic tests are negative and in removing the sicks (only with pulmonary disease). New dangerous kinds of pharmacological multiresistent tuberculosis are appeared in the last years in the world and, with the coinfection HIV-TBC and the reorganization of the surveillance system, represents the major obligation for the next years.

    Anna Tarko


    Full Text Available Introduction. Zonulin (ZO, a new diagnostic biomarker of intestinal permeability, was tested in newborns presenting symptoms of infection and/or inflammation of the gut or being at risk of intestinal pathology. Material and Methods. Serum ZO was assessed in 81 newborns diagnosed with sepsis, necrotizing enterocolitis (NEC, rotavirus infection, and gastroschisis, also in extremely low gestational age babies, and in controls (healthy newborns. ZO concentration was compared to C-reactive protein (CRP and procalcitonin (PCT values, leucocyte and platelet count, basic demographic data, and the value of the Neonatal Therapeutic Intervention Scoring System (NTISS. Results. Median values of ZO were markedly higher in groups with rotavirus infection and gastroschisis (36.0 (1-3Q: 26.0–43.2 and 20.3 (1-3Q: 17.7–28.2 ng/ml, resp. versus controls (3.5 (1-3Q: 2.7–4.8 ng/ml. Its concentration in the NEC group was twice as high as in controls but did not reach statistical significance. ZO levels were not related to NTISS, CRP, and PCT. Conclusions. Zonulin is a promising biomarker of intestinal condition, markedly elevated in rotavirus infections. Its role in defining the severity of necrotizing enterocolitis and the risk for perforation is not well described and needs further evaluation. An increase in zonulin may not be parallel to the release of inflammatory markers, and low CRP should not exclude an injury to neonatal intestine.

  17. Use of the information from experiment by animal

    International Nuclear Information System (INIS)

    Inaba, Jiro


    In order to calculate the radiation dose to various parts of human body tissue from internally deposited radionuclides, we need to know their pattern of uptake and retention within the human body. In the case that appropriate data for man are not available it is commonly necessary to use data collected from experimental animals. Since animal experiment can offer analytical approaches to the subject, the information from the experiment is considered to be rather essential for biologically logical description of the metabolism of the radionuclides. The animal experiment can be divided into three categories by the purpose; i.e., construction of a quantitative metabolic model, evaluation of the factors affecting the parameters used in the model and understanding the mechanisms of the metabolism. Extrapolation of animal data to man are subject to considerable criticism, and probably justifiably so because of the variations among species. An example of species variability is the difference of the whole-body retention rate of radiocesium between newborn of rat and human. Until adequate experimental data are collected from human subjects, we have no choice to rely mainly on information from experimental animals. As our knowledge is insufficient to provide a strong theoretical basis for the extraporation from animal to human, we should be very careful at the practice of the extrapolation, moreover, we should promote the study to establish a good interspecies correlation which will provide a better basis for the extrapolation.

  18. Lightning safety of animals. (United States)

    Gomes, Chandima


    This paper addresses a concurrent multidisciplinary problem: animal safety against lightning hazards. In regions where lightning is prevalent, either seasonally or throughout the year, a considerable number of wild, captive and tame animals are injured due to lightning generated effects. The paper discusses all possible injury mechanisms, focusing mainly on animals with commercial value. A large number of cases from several countries have been analyzed. Economically and practically viable engineering solutions are proposed to address the issues related to the lightning threats discussed.

  19. Our love for animals. (United States)

    Scruton, Roger


    Love does not necessarily benefit its object, and cost-free love may damage both object and subject. Our love of animals mobilises several distinct human concerns and should not be considered always as a virtue or always as a benefit to the animals themselves. We need to place this love in its full psychological, cultural, and moral context in order to assess what form it ought to take if animals are to benefit from it.



    Czerw, Monika


    The benefits of relations between humans and animals have encouraged both scientists and members of other communities to popularize the knowledge in the field of animal-assisted therapy. Currently, animal-assisted therapy has been used not only in therapy, but also in resocialization. The increasing popularity of this form of supporting maladjusted people who are isolated from society or people with disabilities encouraged both practitioners and researchers to organize knowledge, thus reducin...

    Neogi, S B; Sharma, J; Chauhan, M; Khanna, R; Chokshi, M; Srivastava, R; Prabhakar, P K; Khera, A; Kumar, R; Zodpey, S; Paul, V K


    India has contributed immensely toward generating evidence on two key domains of newborn care: Home Based Newborn Care (HBNC) and community mobilization. In a model developed in Gadchiroli (Maharashtra) in the 1990s, a package of Interventions delivered by community health workers during home visits led to a marked decline in neonatal deaths. On the basis of this experience, the national HBNC program centered around Accredited Social Health Activists (ASHAs) was introduced in 2011, and is now the main community-level program in newborn health. Earlier in 2004, the Integrated Management of Neonatal and Childhood Illnesses (IMNCI) program was rolled out with inclusion of home visits by Anganwadi Worker as an integral component. IMNCI has been implemented in 505 districts in 27 states and 4 union territories. A mix of Anganwadi Workers, ASHAs, auxiliary nursing midwives (ANMs) was trained. The rapid roll out of IMNCI program resulted in improving quality of newborn care at the ground field. However, since 2012 the Ministry of Health and Family Welfare decided to limit the IMNCI program to ANMs only and leaving the Anganwadi component to the stewardship of the Integrated Child Development Services. ASHAs, the frontline workers for HBNC, receive four rounds of training using two modules. There are a total of over 900 000 ASHAs per link workers in the country, out of which, only 14% have completed the fourth round of training. The pace of uptake of the HBNC program has been slow. Of the annual rural birth cohort of over 17 million, about 4 million newborns have been visited by ASHA during the financial year 2013-2014 and out of this 120 000 neonates have been identified as sick and referred to health facilities for higher level of neonatal care. Supportive supervision remains a challenge, the role of ANMs in supervision needs more clarity and there are issues surrounding quality of training and the supply of HBNC kits. The program has low visibility in many states

  4. [Care of mothers of newborns in intensive care units: experiences, feelings and expectations of the mothers]. (United States)

    Belli, M A


    The purpose of the study was to examine the experiences, feelings and expectation of mothers of high risk newborns. The population was a group of 20 mothers of high risk newborns of three hospitals in the City of São Paulo. Interview with the mothers was the method of data collection containing opened and structured questions. It was verified that most of the mothers had none or only a little interaction with the newborn after delivery; the eye contact was the most referred during the staying of the newborn in the Intensive Care Unity; all of them demonstrated interest in participating in the care of the newborn and expressed the need of information concerning to the health status of the newborn, the Intensive Care Unity environment and the hospital team. Several were the feelings expressed and the motives that indicated the needs of the mothers.

    Muller, William J.; Jones, Cheryl A.; Koelle, David M.


    Immunologic “immaturity” is often blamed for the increased susceptibility of newborn humans to infection, but the precise mechanisms and details of immunologic development remain somewhat obscure. Herpes simplex virus (HSV) and cytomegalovirus (CMV) are two of the more common severe infectious agents of the fetal and newborn periods. HSV infection in the newborn most commonly occurs after exposure to the virus during delivery, and can lead to a spectrum of clinical disease ranging from isolat...

    Management of newborn infants fell in-hospital is especially challenging given the limited signs and symptoms of intracranial hemorrhage in this age group. We present a case of a four day old well appearing newborn infant found to have a severe epidural hemorrhage requiring emergent surgical drainage. Development of imaging protocols for newborn infants suffering in-hospital falls need to consider the potential consequences of missing actionable intracranial hemorrhage when relying on clinical observation as a management strategy.

  7. A rare cause of hematemesis in newborn: fibrocystic breast disease of mother. (United States)

    Aksoy, Hatice Tatar; Eras, Zeynep; Erdeve, Omer; Dilmen, Ugur


    Hematemesis in a healthy newborn is most often caused by swallowed maternal blood. Maternal blood due to fibrocystic breast disease in human milk has not previously been reported in the literature. We report here a newborn case with hematemesis in which the mother had fibrocystic breast disease, and we want to emphasize this rare entity. Physicians should be aware of this rare condition, and fibrocystic breast disease of the mother should be included in the differential diagnosis of newborns with hematemesis.

  2. Indian draught animals power

    Directory of Open Access Journals (Sweden)

    K. L. Phaniraja

    Full Text Available With the modernization of agriculture, the use of mechanical power in agriculture has increased but draught animal power (DAP continues to be used on Indian farms due to small holdings and hill agriculture. More than 55% of the total cultivated area is still being managed by using draught animals as against about 20% by tractors. India possessed the finest breeds of draught animals. Bullocks, buffaloes and camels are the major draught animals for field operations. Horses, mules, donkeys, yak and mithun are the pack animals for transport. The quality of work from the draught animals depends upon the power developed by them. The design of traditional implements is based on long experience and these have served the purpose of the farmers. However there is plenty of scope to improve the design based on animal-machine-environment interaction so as to have more output and increased efficiency without jeopardizing animal health.

  5. Is animal experimentation fundamental? (United States)

    d'Acampora, Armando José; Rossi, Lucas Félix; Ely, Jorge Bins; de Vasconcellos, Zulmar Acciolli


    The understanding about the utilization of experimental animals in scientific research and in teaching is many times a complex issue. Special attention needs to be paid to attain the understanding by the general public of the importance of animal experimentation in experimental research and in undergraduate medical teaching. Experimental teaching and research based on the availability of animals for experimentation is important and necessary for the personal and scientific development of the physician-to-be. The technological arsenal which intends to mimic experimentation animals and thus fully replace their use many times does not prove to be compatible with the reality of the living animal. The purpose of this paper is to discuss aspects concerning this topic, bringing up an issue which is complex and likely to arouse in-depth reflections.

  7. Principles of animal extrapolation

    Energy Technology Data Exchange (ETDEWEB)

    Calabrese, E.J.


    Animal Extrapolation presents a comprehensive examination of the scientific issues involved in extrapolating results of animal experiments to human response. This text attempts to present a comprehensive synthesis and analysis of the host of biomedical and toxicological studies of interspecies extrapolation. Calabrese's work presents not only the conceptual basis of interspecies extrapolation, but also illustrates how these principles may be better used in selection of animal experimentation models and in the interpretation of animal experimental results. The book's theme centers around four types of extrapolation: (1) from average animal model to the average human; (2) from small animals to large ones; (3) from high-risk animal to the high risk human; and (4) from high doses of exposure to lower, more realistic, doses. Calabrese attacks the issues of interspecies extrapolation by dealing individually with the factors which contribute to interspecies variability: differences in absorption, intestinal flora, tissue distribution, metabolism, repair mechanisms, and excretion. From this foundation, Calabrese then discusses the heterogeneticity of these same factors in the human population in an attempt to evaluate the representativeness of various animal models in light of interindividual variations. In addition to discussing the question of suitable animal models for specific high-risk groups and specific toxicological endpoints, the author also examines extrapolation questions related to the use of short-term tests to predict long-term human carcinogenicity and birth defects. The book is comprehensive in scope and specific in detail; for those environmental health professions seeking to understand the toxicological models which underlay health risk assessments, Animal Extrapolation is a valuable information source.

  8. Newborn care in Indonesia, Lao People's Democratic Republic and the Philippines: a comprehensive needs assessment. (United States)

    Duysburgh, Els; Kerstens, Birgit; Diaz, Melissa; Fardhdiani, Vini; Reyes, Katherine Ann V; Phommachanh, Khamphong; Temmerman, Marleen; Rodriques, Basil; Zaka, Nabila


    Between 1990 and 2011, global neonatal mortality decline was slower than that of under-five mortality. As a result, the proportion of under-five deaths due to neonatal mortality increased. This increase is primarily a consequence of decreasing post-neonatal and child under-five mortality as a result of the typical focus of child survival programmes of the past two decades on diseases affecting children over four weeks of age. Newborns are lagging behind in improved child health outcomes. The aim of this study was to conduct a comprehensive, equity-focussed newborn care assessment and to explore options to improve newborn survival in Indonesia, Lao People's Democratic Republic (PDR) and the Philippines. We assessed newborn health policies, services and care in the three countries through document review, interviews and health facility visits. Findings were triangulated to describe newborns' health status, the health policy and the health system context for newborn care and the equity situation regarding newborn survival. (1) In the three countries, decline of neonatal mortality is lagging behind compared to that of under-five mortality. (2) Comprehensive newborn policies in line with international standards exist, although implementation remains poor. An important factor hampering implementation is decentralisation of the health sector, which created confusion regarding roles and responsibilities. Management capacity and skills at decentralised level were often found to be limited. (3) Quality of newborn care provided at primary healthcare and referral level is generally substandard. Limited knowledge and skills among providers of newborn care are contributing to poor quality of care. (4) Socio-economic and geographic inequities in newborn care are considerable. Similar important challenges for newborn care have been identified in Indonesia, Lao PDR and the Philippines. There is an urgent need to address weak leadership and governance regarding newborn care, quality

  9. Newborn Care in the Home and Health Facility: Formative Findings for Intervention Research in Cambodia

    Directory of Open Access Journals (Sweden)

    Alessandra N. Bazzano


    Full Text Available Global coverage and scale up of interventions to reduce newborn mortality remains low, though progress has been achieved in improving newborn survival in many low-income settings. An important factor in the success of newborn health interventions, and moving to scale, is appropriate design of community-based programs and strategies for local implementation. We report the results of formative research undertaken to inform the design of a newborn health intervention in Cambodia. Information was gathered on newborn care practices over a period of three months using multiple qualitative methods of data collection in the primary health facility and home setting. Analysis of the data indicated important gaps, both at home and facility level, between recommended newborn care practices and those typical in the study area. The results of this formative research have informed strategies for behavior change and improving referral of sick infants in the subsequent implementation study. Collection and dissemination of data on newborn care practices from settings such as these can contribute to efforts to advance survival, growth and development of newborns for intervention research, and for future newborn health programming.

  10. Age-dependent effects of milrinone and levosimendan on ventricular function and haemodynamics in newborn and mature pigs. (United States)

    Hyldebrandt, Janus A; Larsen, Signe H; Schmidt, Michael R; Hjortdal, Vibeke E; Ravn, Hanne B


    Inodilators are used in the treatment of low cardiac output, mainly after cardiac surgery. At present, there is little knowledge of the effect of inodilators in the newborn heart. Immediately after birth and in the neonatal period, the metabolism and physiology of the heart undergo major changes. We hypothesised that effects of the inodilators milrinone and levosimendan on myocardial contractility and haemodynamics under normal physiological conditions were age dependent. Animal studies were conducted on 48 pigs using a closed-chest biventricular conductance catheter method. Pigs in two age groups, that is, 5-6 days and 5-6 weeks, were assigned to milrinone, levosimendan, or a control group. We observed that both milrinone - 19.2% with a p value of 0.05 - and levosimendan - 25.7% with a p value of 0.03 compared with the control group increased cardiac output, as well as myocardial contractility with a maximum pressure development over time: milrinone 28.2%, p = 0.01 and levosimendan 19.4%, p = 0.05. Milrinone improved diastolic performance (p milrinone 34.6%, p milrinone nor levosimendan was able to increase cardiac output in the newborn heart.

  11. Sildenafil prevents the increase of extravascular lung water and pulmonary hypertension after meconium aspiration in newborn piglets. (United States)

    Silvera, F E; Blasina, M F; Vaamonde, L; Tellechea, S; Godoy, C; Zabala, S; Mañana, G; Martell, M; Olivera, W


    Meconium aspiration syndrome causes respiratory failure after birth and in vivo monitoring of pulmonary edema is difficult. The objective of the present study was to assess hemodynamic changes and edema measured by transcardiopulmonary thermodilution in low weight newborn piglets. Additionally, the effect of early administration of sildenafil (2 mg/kg vo, 30 min after meconium aspiration) on this critical parameter was determined in the meconium aspiration syndrome model. Thirty-eight mechanically ventilated anesthetized male piglets (Sus scrofa domestica) aged 12 to 72 h (1660 ± 192 g) received diluted fresh human meconium in the airway in order to evoke pulmonary hypertension (PHT). Extravascular lung water was measured in vivo with a PiCCO monitor and ex vivo by the gravimetric method, resulting in an overestimate of 3.5 ± 2.3 mL compared to the first measurement. A significant PHT of 15 Torr above basal pressure was observed, similar to that of severely affected humans, leading to an increase in ventilatory support. The vascular permeability index increased 57%, suggesting altered alveolocapillary membrane permeability. Histology revealed tissue vessel congestion and nonspecific chemical pneumonitis. A group of animals received sildenafil, which prevented the development of PHT and lung edema, as evaluated by in vivo monitoring. In summary, the transcardiopulmonary thermodilution method is a reliable tool for monitoring critical newborn changes, offering the opportunity to experimentally explore putative therapeutics in vivo. Sildenafil could be employed to prevent PHT and edema if used in the first stages of development of the disease.

  12. 'As soon as the umbilical cord gets off, the child ceases to be called a newborn': sociocultural beliefs and newborn referral in rural Uganda. (United States)

    Nalwadda, Christine K; Waiswa, Peter; Guwatudde, David; Kerber, Kate; Peterson, Stefan; Kiguli, Juliet


    The first week of life is the time of greatest risk of death and disability, and is also associated with many traditional beliefs and practices. Identifying sick newborns in the community and referring them to health facilities is a key strategy to reduce deaths. Although a growing area of interest, there remains a lack of data on the role of sociocultural norms and practices on newborn healthcare-seeking in sub-Saharan Africa and the extent to which these norms can be modified. This study aimed to understand the community's perspective of potential sociocultural barriers and facilitators to compliance with newborn referral. In this qualitative study, focus group discussions (n=12) were conducted with mothers and fathers of babies aged less than 3 months. In addition, in-depth interviews (n=11) were also held with traditional birth attendants and mothers who had been referred by community health workers to seek health-facility-based care. Participants were purposively selected from peri-urban and rural communities in two districts in eastern Uganda. Data were analysed using latent content analysis. The community definition of a newborn varied, but this was most commonly defined by the period between birth and the umbilical cord stump falling off. During this period, newborns are perceived to be vulnerable to the environment and many mothers and their babies are kept in seclusion, although this practice may be changing. Sociocultural factors that influence compliance with newborn referrals to seek care emerged along three sub-themes: community understanding of the newborn period and cultural expectations; the role of community health actors; and caretaker knowledge, experience, and decision-making autonomy. In this setting, there is discrepancy between biomedical and community definitions of the newborn period. There were a number of sociocultural factors that could potentially affect compliance to newborn referral. The widely practised cultural seclusion period

    Chett, Boxley; McKelvie, Jessica


    A method of making an animal litter that includes geopolymerized ash, wherein, the animal litter is made from a quantity of a pozzolanic ash mixed with a sufficient quantity of water and an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. After the geopolymerized ash is formed, it is dried, broken into particulates, and sieved to a desired size. These geopolymerized ash particulates are used to make a non-clumping or clumping animal litter. Odor control may be accomplished with the addition of a urease inhibitor, pH buffer, an odor eliminating agent, and/or fragrance.

  15. Global Liver Proteome Analysis Using iTRAQ Reveals AMPK-mTOR-Autophagy Signaling Is Altered by Intrauterine Growth Restriction in Newborn Piglets. (United States)

    Long, Baisheng; Yin, Cong; Fan, Qiwen; Yan, Guokai; Wang, Zhichang; Li, Xiuzhi; Chen, Changqing; Yang, Xingya; Liu, Lu; Zheng, Zilong; Shi, Min; Yan, Xianghua


    Intrauterine growth restriction (IUGR) impairs fetal growth and development, perturbs nutrient metabolism, and increases the risk of developing diseases in postnatal life. However, the underlying mechanisms by which IUGR affects fetal liver development and metabolism remain incompletely understood. Here, we applied a high-throughput proteomics approach and biochemical analysis to investigate the impact of IUGR on the liver of newborn piglets. As a result, we identified 78 differentially expressed proteins in the three biological replicates, including 31 significantly up-regulated proteins and 47 significantly down-regulated proteins. Among them, a majority of differentially expressed proteins were related to nutrient metabolism and mitochondrial function. Additionally, many significantly down-regulated proteins participated in the mTOR signaling pathway and the phagosome maturation signaling pathway. Further analysis suggested that glucose concentration and hepatic glycogen storage were both reduced in IUGR newborn piglets, which may contribute to AMPK activation and mTORC1 inhibition. However, AMPK activation and mTORC1 inhibition failed to induce autophagy in the liver of IUGR neonatal pigs. A possible reason is that PP2Ac, a potential candidate in autophagy regulation, is significantly down-regulated in the liver of IUGR newborn piglets. These findings may provide implications for preventing and treating IUGR in human beings and domestic animals.

  16. Vaginal delivery to reduce the risk of hypothermia to newborn (United States)

    Zulala, Nuli Nuryanti; Sitaresmi, Mei Neni; Sulistyaningsih


    The prevalence of hypothermia in the world is in the range of 8.5% to 52%, while in Indonesia it is around 47%. Hypothermia has caused 6.3% of neonatal deaths. The method in the process of giving birth determines the way to take care of the newborn. This study aims to observe the effect of the method of delivery on the hypothermia in newborn. This research has obtained an approval from the Ethics Committee of Aisyiyah University, Yogyakarta. This prospective cohort study was conducted to 74 newborns in November 2016. The research subjects were divided into the group of Caesarian section (n = 28) and the group of vaginal delivery (n = 46). Axillary temperature was measured using a digital thermometer at 1st minute, 30th minute, 60th minute, 6th hour, 12th hour and 24th hour. The average temperature difference between the caesarian section group and vaginal delivery group at the 1st minute was at 36°C vs. 36.4° C, at 30th minute at 35.7°C vs. 36.5°C, at 60th minute at 36°C vs. 36.5°C), at 6th hour at 36.2 °C vs. 36.6°C), 12th hour at 36.4°C vs. 36.7°C, and at 24th hour at 36.7°C vs. 36.8°C. The results of the study showed that vaginal delivery could reduce the risk of hypothermia by 1.5 times compared to caesarian section (ρ-value 0.004 CI 95% 1.154 to 1.880)

  17. Screening of newborns for congenital hypothyroidism. Guidance for developing programmes

    International Nuclear Information System (INIS)


    Congenital hypothyroidism is a condition that, if left untreated, can cause lifelong human suffering as a result of severe mental retardation and deficiency of growth. With the involvement of the IAEA, screening programmes to detect congenital hypothyroidism in newborn infants have been introduced successfully in a large number of countries. The cornerstone of these programmes is accurate and reliable screening methods involving isotope techniques and simple medical treatment. The suffering - and heavy social and economic burden - caused by congenital hypothyroidism prompted many countries to institute a formalized screening programme directed at newborns, just as a vaccination programme has become an integral part of child health care. In many other countries however, this type of formalized service has not yet been established. For these countries, the implementation of a neonatal screening programme will bring about a considerable improvement in child health care. It is hoped that the guidance in this publication will be especially useful to the signatories of the United Nations Convention on the Rights of the Child. Several factors that prevail in a country - the climate, political environment, economic development, level of health care and the transportation system - have an influence on the overall operational systems, design and implementation of a screening programme. As such, the design of such a programme will differ greatly from country to country. Nevertheless, neonatal screening programmes have many elements in common. This book draws on the IAEA's experience in this area over more than a decade, and on the results of a regional technical cooperation programme on neonatal screening for congenital hypothyroidism in East Asia (IAEA Project RAS6032). This publication provides guidance aimed specifically at implementing and sustaining programmes for the screening of newborn infants

An inception cohort of premature neonates was followed up from birth until discharge or death to determine if outcome was related to cord blood serum antioxidant capacity, as determined by a manual assay measuring the relative inhibition of oxidation of 2,2'-azino-di-(3-ethylbenzthiazoline)-6 sulfonic acid (ABTS). Possible correlations between antioxidant capacity and various perinatal factors were also tested. Level 3 newborn intensive care unit. All inborn very low-birth-weight neonates from whom cord blood was available and for whom maternal consent was obtained were included. Newborns who died in the first week of life or who had major congenital malformations were excluded. A convenience sample of newborns weighing more than 1500 g was used to perfect assay and explore confounders. Significant ORDP was defined as the presence of intraventricular hemorrhage greater than grade 2, retinopathy of prematurity greater than stage 1, bronchopulmonary dysplasia at the postconceptional age of 36 weeks, or necrotizing enterocolitis with the hypothesis that neonates with ORDP will have lower antioxidant capacity in cord blood serum. Serum antioxidant capacity at birth correlated with gestational age for the entire sample of 41 neonates and for the 26 neonates born before 32 weeks' gestation. After correction for gestational age, cord serum antioxidant capacity did not correlate with maternal smoking, preeclampsia, chorioamnionitis, cord pH Apgar scores, or any of the ORDP studied. Cord serum antioxidant capacity correlates with gestational age but does not predict ORDP risk.

    Savitri, Ary I; Amelia, Dwirani; Painter, Rebecca C; Baharuddin, Mohammad; Roseboom, Tessa J; Grobbee, Diederick E; Uiterwaal, Cuno S P M


    Previous studies suggest that Ramadan exposure during pregnancy might affect the health of women and their babies, particularly through the effect of fasting. This study aimed to evaluate the association between Ramadan exposure and fasting during pregnancy on the birth weight of newborns. This study concerned 1351 pregnant women from a prospective cohort in Jakarta, Indonesia. Ramadan exposure was based on the actual overlap between Ramadan and pregnancy. Women's fasting behaviour was recorded among 139 women who came for antenatal care between 10 July 2013 and 7 August 2013, and those who had fasted for at least 1 d ( n 110) were classified as exposed to Ramadan fasting. Furthermore, a 24 h dietary recall was performed and repeated 1 month later. Birth weight of newborns who were exposed to Ramadan during pregnancy did not significantly differ from those who were not, both in the total and trimester-specific analysis. Maternal fasting did not seem to affect the birth weight of newborns (-72 (95 % CI -258, 114) g; P = 0·44), although there was a non-significant trend towards lower birth weight with fasting in the second and third trimester. Women who fasted had significantly lower total energy, macronutrient and water intake as compared with women who did not. Women's intake was also lower during Ramadan (regardless of their fasting behaviour) as compared with 1 month later. Lifestyle changes that occur with Ramadan and fasting during pregnancy are associated with lower reported energy intake. We cannot conclude on the effect of fasting on birth weight due to low statistical power.

  20. Cerebral microcalcifications in a newborn with congenital tuberculosis. (United States)

    Cifuentes, Yolanda; Murcia, Martha Isabel; Piar, Jorge; Pardo, Patricia


    Tuberculosis is a serious public health problem worldwide. In 2012, the World Health Organization estimated 8.6 million new cases and 1.3 million deaths due to the disease. In 2011, the incidence in Colombia was 24 cases per 100,000 inhabitants. There is little information about tuberculosis in pregnant women, and congenital infection is considered a rare disease that is difficult to diagnose, leads to high mortality, and may be confused with tuberculosis acquired after birth. In addition, it has been associated with HIV infection in mothers and infants. Moreover, there is increasing incidence of congenital syphilis in the world. In Colombia, the prevalence is 2.5 cases per 1,000 births and its frequency in the Instituto Materno Infantil-Hospital La Victoria is one case per 57 births. We report the case of a newborn under treatment for congenital syphilis and in whom microcalcifications were found in a transfontanelar ultrasound. This finding warned about the existence of another infectious agent. PCR was negative for cytomegalovirus, and IgM titers for toxoplasma, rubella and herpes I and II were also negative. After learning about a history of incomplete treatment for tuberculosis in the mother, we suspected the presence of an infection by the tubercle bacillus in the newborn. No acid-fast bacilli were demonstrated in three gastric juice samples. The IS6110 PCR assay was found positive in cerebrospinal fluid and urine, but not in blood. The newborn was treated with crystalline penicillin for 10 days along with isoniazid, rifampicin, pyrazinamide and streptomycin. The patient is currently under clinical monitoring.

    Full Text Available Background & objectives: Weight loss and hypernatremic dehydration is a common problem in infants with inadequate nutrition. Determination of risk factors and clinical characteristics of these neonates may help to prevent or early detection of hypernatremia. This study designed to determine the prevalence of clinical signs and risk factors for hypernatremic dehydration. Methods: This study is a sectional descriptive study that conducted on 418 newborns during 1385 to 1393 AHS that referred to Ghaem hospital in Mashhad. The hypernatremic group consisted of 197 neonates with serum sodium level higher than 150 mg/dl and 221 isonatremic newborns with sodium level less than 150 mmol/L were included as controls. Both groups were compared in terms of clinical symptoms of dehydration and maternal risk factors. All data were recorded and coded. Data analysis performed using paired T test and chi square tests by SPSS 16 software. Results: In the present study, 2.8% of infants were hypernatremic. The most common symptoms were neonatal jaundice (62.2%, hyperthermia (25.8%, lethargy (23.6%, agitation (20.8 % and mucous membranes dryness (17.2%. Problems in pregnancy (p=0.002, inappropriate feeding techniques (p=0.000, the first lactation duration (p=0.022 and frequency per day (p=0.000 had statistically significant difference between case and control groups. Conclusion: Prevalence of hypernatremic dehydrationis considerable in our study and identifying the risk factors may help to reduce its incidence or exacerbation. Weight loss, especially in newborns having jaundice, hyperthermia and irritability, may be helpful in the early diagnosis of hypernatremic dehydration

    Objective: To explore routine magnetic resonance imaging characteristics of newborn bilirubin encephalopathy (NBE). Methods: MRI features and clinical data of 17 patients with Newborn bilirubin encephalopathy were retrospectively analyzed, globus pallidus (GP)and subthalamic signal intensity was evaluated. The increase of GP signal intensity and serum total bilirubin peak value were analyzed using pearson correlation analysis. Serum total bilirubin peak value between patients with high signal in the subthalamic nuclei on T 1 WI and patients without high signal in the subthalamic nuclei were compared statistically. Results: The main MRI presentation in the NBE group was abnormally increased signal intensity in the GP on T 1 WI, which was not apparent on T 2 WI. One patient showed abnormal high signal intensity in the posteromedial part of GP. Nine patients had high signal in the subthalamic nuclei on T 1 WI and normal signal on T 2 WI. Four patients showed high signal in the brainstem with sparing of dorsal pontine. The increase in value of GP signal intensity was 249.0-423.8 in 12 patients and their serum total bilirubin peak values were 366.0-983.3 μmol/L. A positive correlation was found between increase of GP signal intensity and serum total bilirubin peak value. The serum total bilirubin level of abnormal subthalamic group and normal subthalamic group were 660.7±192.4 μmol/L and 513.3±107.51 μmol/L respectively. The difference between the two groups was not statistically significant (t=1.914, P>0.05). Conclusion: The routine MRI has some characteristics and is useful in the diagnosis of newborn bilirubin encephalopathy. (authors)

  3. Paracetamol (acetaminophen) efficacy and safety in the newborn. (United States)

    Cuzzolin, Laura; Antonucci, Roberto; Fanos, Vassilios


    Neonates can perceive pain, therefore an adequate analgesic therapy is a major issue not only from an ethical perspective but also to improve short- and long-term outcome. Fever during the neonatal period requires hospitalization and needs a treatment with an antipyretic agent because of the high risk of severe complications. Paracetamol (acetaminophen), the most commonly prescribed drug in paediatric patients for its analgesic and antipyretic effects, is the only agent recommended for use as an antipyretic in the newborn and has been recently proposed as a supplement therapy to opioids for postoperative analgesia. This article aims to give an updated overview on the use of paracetamol in newborns by presenting its pharmacological profile (mechanism of action, pharmacokinetics), recommendations for dosing regimens (oral or rectal administration: 25-30 mg/kg/day in preterm neonates of 30 weeks' gestation, 45 mg/kg/day in preterm neonates of 34 weeks' gestation, 60 mg/kg/day in term neonates; i.v. administration: indicatively 20-40 mg/kg/day depending on gestational age, with some differences among various guidelines) and clinical uses (more commonly as analgesic/antipyretic by oral or rectal route, but also i.v. in anaesthesia for postoperative analgesia and painful procedures in Neonatal Intensive Care Units). Moreover, drug tolerability is discussed in the light of its potential hepatotoxicity and the unique characteristics of the newborn patient. By analyzing the available literature and the dosing guidelines, a mismatch exists between the current clinical use of paracetamol and the recommendations, suggesting a cautious approach particularly in extremely preterm neonates.

  4. Association Between Newborn Metabolic Profiles and Pediatric Kidney Disease

    Manish M. Sood


    Full Text Available Introduction: Metabolomics offers considerable promise in early disease detection. We set out to test the hypothesis that routine newborn metabolic profiles at birth, obtained through screening for inborn errors of metabolism, would be associated with kidney disease and add incremental information to known clinical risk factors. Methods: We conducted a population-level cohort study in Ontario, Canada, using metabolic profiles from 1,288,905 newborns from 2006 to 2015. The primary outcome was chronic kidney disease (CKD or dialysis. Individual metabolites and their ratio combinations were examined by logistic regression after adjustment for established risk factors for kidney disease and incremental risk prediction measured. Results: CKD occurred in 2086 (0.16%, median time 612 days and dialysis in 641 (0.05%, median time 99 days infants and children. Individual metabolites consisted of amino acids, acylcarnitines, markers of fatty acid oxidation, and others. Base models incorporating clinical risk factors only provided c-statistics of 0.61 for CKD and 0.70 for dialysis. The addition of identified metabolites to risk prediciton models resulted in significant incremental improvement in the performance of both models (CKD model: c-statistic 0.66 NRI 0.36 IDI 0.04, dialysis model: c-statistic 0.77 NRI 0.57 IDI 0.09. This was consistent after internal validation using bootstrapping and a sensitivity analysis excluding outcomes within the first 30 days. Conclusion: Routinely collected screening metabolites at birth are associated with CKD and the need for dialytic therapies in infants and children, and add incremental information to traditional clinical risk factors.

  5. Reporting Newborn Audiologic Results to State EHDI Programs. (United States)

    Chung, Winnie; Beauchaine, Kathryn L; Grimes, Alison; O'Hollearn, Tammy; Mason, Craig; Ringwalt, Sharon

    All US states and territories have an Early Hearing Detection and Intervention (EHDI) program to facilitate early hearing evaluation and intervention for infants who are deaf or hard of hearing. To ensure efficient coordination of care, the state EHDI programs rely heavily on audiologists' prompt reporting of a newborn's hearing status. Several states have regulations requiring mandatory reporting of a newborn's hearing status. This is an important public health responsibility of pediatric audiologists. Reasons for failing to report vary. The Early Hearing Detection and Intervention-Pediatric Audiology Links to Services (EHDI) facility survey was used to inform reporting compliance of audiology facilities throughout the United States. The survey was disseminated via articles, newsletters, and call-to-action notices to audiologists. Among 1024 facilities surveyed, 88 (8.6%) reported that they did not report newborn's hearing findings to their state EHDI program. Not knowing how to report to the state EHDI program was the most frequently chosen reason (60%). However, among the 936 facilities that were compliant with the reporting requirements, 51 estimated that they reported less than two-third of all hearing evaluation results (5.4%). Some facilities did not report a normal-hearing result and some failed to report because they assumed another facility would report the hearing results. Survey results indicated that audiologists were compliant reporting hearing results to the state EHDI programs. However, there is room for improvement. Regular provider outreach and training by the state EHDI program is necessary to ensure those who are not reporting will comply and to clarify reporting requirements for those who are already compliant.

  6. Small renal size in newborns with spina bifida: possible causes. (United States)

    Montaldo, Paolo; Montaldo, Luisa; Iossa, Azzurra Concetta; Cennamo, Marina; Caredda, Elisabetta; Del Gado, Roberto


    Previous studies reported that children with neural tube defects, but without any history of intrinsic renal diseases, have small kidneys when compared with age-matched standard renal growth. The aim of this study was to investigate the possible causes of small renal size in children with spina bifida by comparing growth hormone deficiency, physical limitations and hyperhomocysteinemia. The sample included 187 newborns with spina bifida. Renal sizes in the patients were assessed by using maximum measurement of renal length and the measurements were compared by using the Sutherland monogram. According to the results, the sample was divided into two groups--a group of 120 patients with small kidneys (under the third percentile) and a control group of 67 newborns with normal kidney size. Plasma total homocysteine was investigated in mothers and in their children. Serum insulin-like growth factor-1 (IGF-1) levels were measured. Serum IGF-1 levels were normal in both groups. Children and mothers with homocysteine levels >10 μmol/l were more than twice as likely to have small kidneys and to give to birth children with small kidneys, respectively, compared with newborns and mothers with homocysteine levels <10 μmol/l. An inverse correlation was also found between the homocysteine levels of mothers and kidney sizes of children (r = - 0.6109 P ≤ 0.01). It is highly important for mothers with hyperhomocysteinemia to be educated about benefits of folate supplementation in order to reduce the risk of small renal size and lower renal function in children.

  7. The Effect of Swaddling on Pain, Vital Signs, and Crying Duration during Heel Lance in Newborns. (United States)

    Erkut, Zeynep; Yildiz, Suzan


    To determine the effect of swaddling on pain, vital signs, and crying duration during heel lance in the newborn. This was a randomized controlled study of 74 (control: 37, experiment: 37) newborns born between December 2013 and February 2014 at the Ministry of Health Bagcılar Training and Research Hospital. An information form, observation form, and Neonatal Infant Pain Scale were used as data collection tools. Data from the pain scores, peak heart rates, oxygen saturation, total crying time, and duration of the procedure were collected using a video camera. Newborns in the control group underwent routine heel lance, whereas newborns in the experimental group underwent routine heel lance while being swaddled by the researcher. The newborns' pain scores, peak heart rates, oxygen saturation values, and crying durations were evaluated using video recordings made before, during, and 1, 2, and 3 minutes after the procedure. Pain was assessed by a nurse and the researcher. No statistically significant difference was found in the characteristics of the two groups (p > .05). The mean pain scores of swaddled newborns during and after the procedure were lower than the nonswaddled newborns (p  .05). Although there was no significant difference in oxygen saturation values before and during the procedure (p > .05), oxygen saturation values of swaddled newborns were higher afterward (p < .05). For this study sample, swaddling was an effective nonpharmacologic method to help reduce pain and crying in an effort to soothe newborns. Although pharmacologic pain management is the gold standard, swaddling can be recommended as a complementary therapy for newborns during painful procedures. Swaddling is a quick and simple nonpharmacologic method that can be used by nurses to help reduce heel stick pain in newborns. Copyright © 2017 American Society for Pain Management Nursing.

    Some applications of the use of radioisotopes and radiation in animal health and production research are reviewed. These include various techniques associated with both the qualitative localization and quantitative measurements of isotopes in animals; comparator studies in which measurement of the radioactivity in one part of a system will allow computation of the mass or volume in another part; in vivo and in vitro applications of isotope dilution studies; and the use of isotopes in dynamic systems analyses. The use of stable isotopes in mass spectrometry, activation analysis and nuclear magnetic resonance in animal research is also briefly reviewed. Finally some of the successful uses of radiation produced by radioactive sources or various types of generators of electromagnetic radiations in animal production and health studies are described.

  17. Animal transportation networks (United States)

    Perna, Andrea; Latty, Tanya


    Many group-living animals construct transportation networks of trails, galleries and burrows by modifying the environment to facilitate faster, safer or more efficient movement. Animal transportation networks can have direct influences on the fitness of individuals, whereas the shape and structure of transportation networks can influence community dynamics by facilitating contacts between different individuals and species. In this review, we discuss three key areas in the study of animal transportation networks: the topological properties of networks, network morphogenesis and growth, and the behaviour of network users. We present a brief primer on elements of network theory, and then discuss the different ways in which animal groups deal with the fundamental trade-off between the competing network properties of travel efficiency, robustness and infrastructure cost. We consider how the behaviour of network users can impact network efficiency, and call for studies that integrate both network topology and user behaviour. We finish with a prospectus for future research. PMID:25165598

  19. [Alternatives to animal testing]. (United States)

    Fabre, Isabelle


    The use of alternative methods to animal testing are an integral part of the 3Rs concept (refine, reduce, replace) defined by Russel & Burch in 1959. These approaches include in silico methods (databases and computer models), in vitro physicochemical analysis, biological methods using bacteria or isolated cells, reconstructed enzyme systems, and reconstructed tissues. Emerging "omic" methods used in integrated approaches further help to reduce animal use, while stem cells offer promising approaches to toxicologic and pathophysiologic studies, along with organotypic cultures and bio-artificial organs. Only a few alternative methods can so far be used in stand-alone tests as substitutes for animal testing. The best way to use these methods is to integrate them in tiered testing strategies (ITS), in which animals are only used as a last resort.

  20. Hybrid computational phantoms of the male and female newborn patient: NURBS-based whole-body models

    International Nuclear Information System (INIS)

    Lee, Choonsik; Lodwick, Daniel; Hasenauer, Deanna; Williams, Jonathan L; Lee, Choonik; Bolch, Wesley E


    Anthropomorphic computational phantoms are computer models of the human body for use in the evaluation of dose distributions resulting from either internal or external radiation sources. Currently, two classes of computational phantoms have been developed and widely utilized for organ dose assessment: (1) stylized phantoms and (2) voxel phantoms which describe the human anatomy via mathematical surface equations or 3D voxel matrices, respectively. Although stylized phantoms based on mathematical equations can be very flexible in regard to making changes in organ position and geometrical shape, they are limited in their ability to fully capture the anatomic complexities of human internal anatomy. In turn, voxel phantoms have been developed through image-based segmentation and correspondingly provide much better anatomical realism in comparison to simpler stylized phantoms. However, they themselves are limited in defining organs presented in low contrast within either magnetic resonance or computed tomography images-the two major sources in voxel phantom construction. By definition, voxel phantoms are typically constructed via segmentation of transaxial images, and thus while fine anatomic features are seen in this viewing plane, slice-to-slice discontinuities become apparent in viewing the anatomy of voxel phantoms in the sagittal or coronal planes. This study introduces the concept of a hybrid computational newborn phantom that takes full advantage of the best features of both its stylized and voxel counterparts: flexibility in phantom alterations and anatomic realism. Non-uniform rational B-spline (NURBS) surfaces, a mathematical modeling tool traditionally applied to graphical animation studies, was adopted to replace the limited mathematical surface equations of stylized phantoms. A previously developed whole-body voxel phantom of the newborn female was utilized as a realistic anatomical framework for hybrid phantom construction. The construction of a hybrid

    Ujeno, Y.; Takimoto, K.


    The compartment models of transplacental transfer of tritiated water injected into pregnant females, to foetuses and of lacteal transfer of tritiated water injected into nursing females, to sackling newborn mice were presented, respectively. There are many assumptions in the models and they do not fit the experimental data well. However, some of the differences between the models and experimental data can be qualitatively explained by physiological reasoning. The changes in the kidney functions of pregnant women are also the important factors which have to be considered to analyze the dynamics. The present dynamics analyses with mice can contribute to the understanding of the dynamics of tritiated water in humans. (Namekawa, K.)

  2. Neutropenia in infants with hemolytic disease of the newborn. (United States)

    Blanco, Esther; Johnston, Donna L


    This study examined the incidence, outcome and risk factors of neutropenia in infants with hemolytic disease of the newborn (HDN). A retrospective chart review was performed on infants with HDN. Of 69 evaluable infants, 45% developed neutropenia. Only one infectious complication was recorded. In most instances the neutropenia resolved spontaneously, but in seven infants it persisted for a median of 397 days. Males were at higher risk for developing neutropenia, but severity of HDN, antibody specificity, or therapy were not significant risk factors. Neutropenia is a common feature of HDN, regardless of severity of disease, treatment received, or antibody specificity. Copyright © 2011 Wiley Periodicals, Inc.

  3. A Case of Rhizomelic Chondrodysplasia Punctata in Newborn

    Directory of Open Access Journals (Sweden)

    Nalan Karabayır


    Full Text Available Rhizomelic chondrodysplasia punctate (RCDP is a rare autosomal recessive peroxisomal disease. The main features of the disease are shortening of the proximal long bones, punctate calcifications located in the epiphyses of long bones and in soft tissues around joints and vertebral column, vertebral clefting, dysmorphic face, and severe growth retardation, whereas cervical spinal stenosis may also rarely be present. Imaging of the brain and spinal cord in patients with this disorder may aid prognosis and guide management decisions. We report the newborn diagnosed as CDP with cervical stenosis. Our aim is to discuss current knowledge on etiopathogenesis as well as radiological and clinical symptoms of diseases associated with CDP.

    Full Text Available Urinary Ascites in the newborn is a very rare condition. It is commonly secondary to posterior urethral valves (PUV which are membranous folds extending from proximal urethra leading to obstruction to urine flow. Here we report a two days old male neonate delivered full term in a hospital who presented with gross, uniform tense distension of abdomen with massive scrotal oedema, secondary to massive urinary ascites as a result of rupture of renal calyces. In addition there was a peri-renal urinoma.

    In this paper we study the cerebrovascular dynamics in newborn rats using the wavelet-based multifractal formalism in order to reveal effective markers of early pathological changes in the macro- and microcirculation at the hidden stage of the development of intracranial hemorrhage (ICH). We demonstrate that the singularity spectrum estimated with the wavelet-transform modulus maxima (WTMM) technique allows clear characterization of a reduced complexity of blood flow dynamics and changes of the correlation properties at the transformation of normal physiological processes into pathological dynamics that are essentially different at the level of large and small blood vessels

  9. Timing of Excessive Weight Gain During Pregnancy Modulates Newborn Anthropometry. (United States)

    Ruchat, Stephanie-May; Allard, Catherine; Doyon, Myriam; Lacroix, Marilyn; Guillemette, Laetitia; Patenaude, Julie; Battista, Marie-Claude; Ardilouze, Jean-Luc; Perron, Patrice; Bouchard, Luigi; Hivert, Marie-France


    Excessive gestational weight gain (GWG) is associated with increased birth weight and neonatal adiposity. However, timing of excessive GWG may have a differential impact on birth outcomes. The objective of this study was to compare the effect of early and mid/late excessive GWG on newborn anthropometry in the context of the Canadian clinical recommendations that are specific for first trimester and for second/third trimesters based on maternal pre-pregnancy BMI. We included 607 glucose-tolerant women in our main analyses, after excluding women who had less than the recommended total GWG. Maternal body weight was measured in early pregnancy, mid-pregnancy, and late pregnancy. Maternal and fetal clinical outcomes were collected, including newborn anthropometry. Women were divided into four groups according to the Canadian guidelines for GWG in the first and in the second/third trimesters: (1) "overall non-excessive" (reference group); (2) "early excessive GWG"; (3) "mid/late excessive GWG"; and (4) "overall excessive GWG." Differences in newborn anthropometry were tested across GWG categories. Women had a mean (±SD) pre-pregnancy BMI of 24.7 ± 5.2 kg/m(2) and total GWG of 15.3 ± 4.4 kg. Women with mid/late excessive GWG gave birth to heavier babies (gestational age-adjusted birth weight z-score 0.33 ± 0.91) compared with women in the reference group (0.00 ± 0.77, P = 0.007), whereas women with early excessive GWG gave birth to babies of similar weight (gestational age-adjusted z-score 0.01 ± 0.86) to the reference group (0.00 ± 0.77, P = 0.84). When we stratified our analyses and investigated women who gained within the recommendations for total GWG, mid/late excessive GWG specifically was associated with greater newborn size, similar to our main analyses. Excessive GWG in mid/late pregnancy in women who did not gain weight excessively in early pregnancy is associated with increased birth size, even in those who gained within the Canadian recommendations

  10. Severe Bloch—Sulzberger syndrome in a newborn baby

    Directory of Open Access Journals (Sweden)

    T. I. Chernikova


    Full Text Available The diagnosis of neonatal skin diseases is often a complicated interdisciplinary problem. The authors present the data available in the literature data and their clinical observation of a newborn baby with Bloch—Sulzberger syndrome, a rare genetic dermatosis. The specific feature of the observation is the development of the disease immediately after birth and its complex differential diagnosis. Central nervous system involvement as epilepsy syndrome determines the severity of the patient's condition and seriously affects the prognosis of the disease. The issues of in-depth studies using molecular genetic technologies that enhance the value of medical genetic counseling to the family are discussed.

    Full Text Available BACKGROUND: The influence of multiple maternal and pregnancy characteristics on offspring cardiometabolic traits at birth is not well understood and was evaluated in this study. METHODS AND FINDINGS: The Family Atherosclerosis Monitoring In earLY life (FAMILY Study prospectively evaluated 11 cardiometabolic traits in 901 babies born to 857 mothers. The influence of maternal age, health (pre-pregnancy weight, blood pressure, glycemic status, lipids, health behaviors (diet, activity, smoking and pregnancy characteristics (gestational age at birth, gestational weight gain and placental-fetal ratio were examined. Greater gestational age influenced multiple newborn cardiometabolic traits including cord blood lipids, glucose and insulin, body fat and blood pressure. In a subset of 442 singleton mother/infant pairs, principal component analysis grouped 11 newborn cardiometabolic traits into 5 components (anthropometry/insulin, 2 lipid components, blood pressure and glycemia, accounting for 74% of the variance of the 11 outcome variables. Determinants of these components, corrected for sex and gestational age, were examined. Baby anthropometry/insulin was independently predicted by higher maternal pre-pregnancy weight (standardized estimate 0.30 and gestational weight gain (0.30; both p<0.0001 and was inversely related to smoking during pregnancy (-0.144; p = 0.01 and maternal polyunsaturated to saturated fat intake (-0.135;p = 0.01. Component 2 (HDL-C/Apo Apolipoprotein1 was inversely associated with maternal age. Component 3 (blood pressure was not clustered with any other newborn cardiometabolic trait and no associations with maternal pregnancy characteristics were identified. Component 4 (triglycerides was positively associated with maternal hypertension and triglycerides, and inversely associated with maternal HDL and age. Component 5 (glycemia was inversely associated with placental/fetal ratio (-0.141; p = 0.005. LDL-C was a bridging

  14. Modelling Farm Animal Welfare (United States)

    Collins, Lisa M.; Part, Chérie E.


    Simple Summary In this review paper we discuss the different modeling techniques that have been used in animal welfare research to date. We look at what questions they have been used to answer, the advantages and pitfalls of the methods, and how future research can best use these approaches to answer some of the most important upcoming questions in farm animal welfare. Abstract The use of models in the life sciences has greatly expanded in scope and advanced in technique in recent decades. However, the range, type and complexity of models used in farm animal welfare is comparatively poor, despite the great scope for use of modeling in this field of research. In this paper, we review the different modeling approaches used in farm animal welfare science to date, discussing the types of questions they have been used to answer, the merits and problems associated with the method, and possible future applications of each technique. We find that the most frequently published types of model used in farm animal welfare are conceptual and assessment models; two types of model that are frequently (though not exclusively) based on expert opinion. Simulation, optimization, scenario, and systems modeling approaches are rarer in animal welfare, despite being commonly used in other related fields. Finally, common issues such as a lack of quantitative data to parameterize models, and model selection and validation are discussed throughout the review, with possible solutions and alternative approaches suggested.

  15. Animal and human influenzas. (United States)

    Peiris, M; Yen, H-L


    Influenza type A viruses affect humans and other animals and cause significant morbidity, mortality and economic impact. Influenza A viruses are well adapted to cross species barriers and evade host immunity. Viruses that cause no clinical signs in wild aquatic birds may adapt in domestic poultry to become highly pathogenic avian influenza viruses which decimate poultry flocks. Viruses that cause asymptomatic infection in poultry (e.g. the recently emerged A/H7N9 virus) may cause severe zoonotic disease and pose a major pandemic threat. Pandemic influenza arises at unpredictable intervals from animal viruses and, in its global spread, outpaces current technologies for making vaccines against such novel viruses. Confronting the threat of influenza in humans and other animals is an excellent example of a task that requires a One Health approach. Changes in travel, trade in livestock and pets, changes in animal husbandry practices, wet markets and complex marketing chains all contribute to an increased risk of the emergence of novel influenza viruses with the ability to cross species barriers, leading to epizootics or pandemics. Coordinated surveillance at the animal- human interface for pandemic preparedness, risk assessment, risk reduction and prevention at source requires coordinated action among practitioners in human and animal health and the environmental sciences. Implementation of One Health in the field can be challenging because of divergent short-term objectives. Successful implementation requires effort, mutual trust, respect and understanding to ensure that long-term goals are achieved without adverse impacts on agricultural production and food security.

    The importance of prebiotics consumption is increasing all over the world due to their beneficial effects on health. Production of better prebiotics from endemic plants raises possibilities to enhance nutritional effects in vulnerable population groups. Fructans derived from Agave Plant have demonstrated their safety and efficacy as prebiotics in animal models. Recently, the safety in humans of two fructans obtained from Agave tequilana (Metlin(®) and Metlos(®)) was demonstrated. This study aimed to demonstrate the efficacy as prebiotics of Metlin(®) and Metlos(®) in newborns of a randomized, double blind, controlled trial with a pilot study design. Biological samples were taken at 20 ± 7 days, and three months of age from healthy babies. Outcomes of efficacy include impact on immune response, serum ferritin, C-reactive protein, bone metabolism, and gut bacteria changes. There were differences statistically significant for the groups of infants fed only with infant formula and with formula enriched with Metlin(®) and Metlos(®). Our results support the efficacy of Metlin(®) and Metlos(®) as prebiotics in humans, and stand the bases to recommend their consumption., NCT 01251783.

    Full Text Available Hypogalactia has a relative high frequency in women having delivered preterm infants, who often have difficulties in maintaining a sufficient production of milk for their infants’ needs over prolonged periods of time. Recent studies have shown a potential galactogogue effect of silymarin on milk production in animal models (cows and rats and in humans (mothers of term newborns; nonetheless, none of the studies conducted on humans consisted of double-blind randomized clinical trials and no data are available concerning mothers who delivered preterm infants. The aim of our study was to assess the efficacy of silymarin (BIO-C® as galactogogue and its tolerability in mothers who delivered preterm infants. We enrolled 50 mothers at 10±1 days post-partum who had delivered infants at ® and placebo arms. No adverse events were observed in the 2 arms among mothers and infants, and silymarin and its metabolites were not detectable in the analyzed human milk samples. Further investigation on specific patient groups affected by hypogalactia, defined according to stricter criteria, should be planned to assess the efficacy of the product in increasing milk production.

  4. Perinatal upregulation of intestinal transport of carnitine (C) in newborn pigs

    International Nuclear Information System (INIS)

    Li, B.U.K.; Murray, R.D.; Heitlinger, L.A.; McClung, H.J.; Hughes, A.M.; O'Dorisio, T.M.; Sloan, H.R.


    Since C facilitates the perinatal transition from carbohydrate to lipid-derived energy, the authors examined the contribution of intestinal transport of dietary C to this process by determining [C]'s in sow's milk, pig jejunum and liver, and C flux across the jejunum (J m-s ) as a function of postnatal age. The authors measured portal venous glucagon [G] and insulin [l] as potential regulatory signals and attempted to alter intestinal transport of C by infusing G. Pigs at days 1-7 (NB-newborn), 14-16 (SU-suckling) and 33-35 (WN-weanling) were studied. [C]'s in sow milk, piglet jejunum, and liver were determined. Fluxes were measured in an Ussing chamber and in an in situ recirculating jejunal perfusion. The effect of an IV infusion of G on [ 3 H]C absorption was evaluated in a single animal; an adjacent jejunal segment received saline. Sow's milk and liver [C]'s, and jejunal C transport were highest following birth and declined towards weaning. Plasma [G] and the G:I ratio demonstrated a parallel temporal pattern. The G-stimulated jejunal segment removed 53% of the C and the non-stimulated control segment, 8%. It was concluded that during the perinatal metabolic transition, enhanced intestinal nutrient assimilation promotes the transfer of dietary C to the liver where it could facilitate fatty acid oxidation. This pattern of upregulated intestinal transport immediately after birth may be mediated by pancreatic G and I secretion

  5. Correlation among cytokines, bronchopulmonary dysplasia and modality of ventilation in preterm newborns: improvement with melatonin treatment. (United States)

    Gitto, Eloisa; Reiter, Russel J; Sabatino, Giuseppe; Buonocore, Giuseppe; Romeo, Carmelo; Gitto, Placido; Buggé, Concetta; Trimarchi, Giuseppe; Barberi, Ignazio


    Improved survival because of advances in neonatal care has resulted in an increased number of infants at risk for chronic lung disease. Even though the etiology of lung injury is multifactorial, recent animal and clinical data indicate that pulmonary damage depends in large part on the ventilatory strategies used. Ventilator-associated lung injury was believed to result from the use of high pressure, thus, the term barotraumas. This trauma is believed to involve free-radical damage. Oxidant injury is a serious cause of lung injury. In the present study, 110 newborns with respiratory distress syndrome were studied; 55 were treated with melatonin and the other 55 with placebo. All the subjects were mechanically ventilated with or without guaranteed volume. Proinflammatory cytokines [interleukin (IL)-6, IL-8 and tumor necrosis factor (TNF)-alpha] were measured in tracheobronchial aspirate and the clinical outcome was evaluated. Melatonin treatment reduced the proinflammatory cytokines and improved the clinical outcome. The beneficial action of melatonin presumably related to its antioxidative actions.

  6. Hypothermia reduces cerebral metabolic rate and cerebral blood flow in newborn pigs

    International Nuclear Information System (INIS)

    Busija, D.W.; Leffler, C.W.


    The authors examined effects of hypothermia on cerebral metabolic rate and cerebral blood flow in anesthetized, newborn pigs (1-4 days old). Cerebral blood flow (CBF) was determined with 15-μm radioactive microspheres. Regional CBF ranged from 44 to 66 ml·min -1 ·100 g -1 , and cerebral metabolic rate was 1.94 ± 0.23 ml O 2 ·100 g -1 ·min -1 during normothermia (39 degree C). Reduction of rectal temperature to 34-35 degree C decreased CBF and cerebral metabolic rate 40-50%. In another group of piglets, they examined responsiveness of the cerebral circulation to arterial hypercapnia during hypothermia. Although absolute values for normocapnic and hypercapnic CBF were reduced by hypothermia and absolute values for normocapnic and hypercapnic cerebrovascular resistance were increased, the percentage changes from control in these variables during hypercapnia were similar during normothermia and hypothermia. In another group of animals that were maintained normothermic and exposed to two episodes of hypercapnia, there was no attenuation of cerebrovascular dilation during the second episode. They conclude that hypothermia reduces CBF secondarily to a decrease in cerebral metabolic rate and that percent dilator responsiveness to arterial hypercapnia is unaltered when body temperature is reduced

  7. The gastrointestinal absorption and retention of niobium in adult and newborn guinea pigs

    International Nuclear Information System (INIS)

    Harrison, J.D.; Haines, J.W.; Popplewell, D.S.


    The gastrointestinal absorption of 95 Nb ingested in milk by adult guinea pigs on a milk-supplemented diet was estimated as 0.8±0.2% (SEM; n=4) and a value of 1.4±0.2% obtained for guinea pigs fasted for 24 h before and 2 h after oral administration of 95 Nb in a citrate solution. The absorption in 2-day-old animals given the 95 Nb-citrate solution was estimated as 1.5±0.2% (SEM; n=3). These results support the values currently used for radiological protection purposes to calculate doses from the ingestion of niobium isotopes; these are 1% for adults and 2% for infants in the first year of life. Intestinal retention of niobium in newborn guinea pigs was low, unlike retention in other species, but consistent with observations of the retention of other elements in guinea pigs. It is considered that retention in human neonates is likely to be most similar to that in guinea pigs. (author)

  9. Data integration and warehousing: coordination between newborn screening and related public health programs. (United States)

    Therrell, Bradford L


    At birth, patient demographic and health information begin to accumulate in varied databases. There are often multiple sources of the same or similar data. New public health programs are often created without considering data linkages. Recently, newborn hearing screening (NHS) programs and immunization programs have virtually ignored the existence of newborn dried blood spot (DBS) newborn screening databases containing similar demographic data, creating data duplication in their 'new' systems. Some progressive public health departments are developing data warehouses of basic, recurrent patient information, and linking these databases to other health program databases where programs and services can benefit from such linkages. Demographic data warehousing saves time (and money) by eliminating duplicative data entry and reducing the chances of data errors. While newborn screening data are usually the first data available, they should not be the only data source considered for early data linkage or for populating a data warehouse. Birth certificate information should also be considered along with other data sources for infants that may not have received newborn screening or who may have been born outside of the jurisdiction and not have birth certificate information locally available. This newborn screening serial number provides a convenient identification number for use in the DBS program and for linking with other systems. As a minimum, data linkages should exist between newborn dried blood spot screening, newborn hearing screening, immunizations, birth certificates and birth defect registries.

    To report the birth prevalence, risk factors, characteristics, and location of fundus hemorrhages (FHs) of the retina and optic nerve present in newborns at birth. Prospective cohort study at Stanford University School of Medicine. All infants who were 37 weeks postmenstrual age or older and stable were eligible for screening. Infants with known or suspected infectious conjunctivitis were excluded. Infants born at Lucile Packard Children's Hospital (LPCH) from July 25, 2013, through July 25, 2014, were offered universal newborn screening via wide-angle digital retinal photography in the Newborn Eye Screen Test study. Maternal, obstetric, and neonatal factors were obtained from hospital records. The location, retinal layer, and laterality of FH were recorded by 1 pediatric vitreoretinal specialist. Birth prevalence of FH. Secondary outcomes included rate of adverse events, risk factors for FH, hemorrhage characteristics, and adverse events. The birth prevalence of FH in this study was 20.3% (41/202 infants). Ninety-five percent of FHs involved the periphery, 83% involved the macula, and 71% involved multiple layers of the retina. The fovea was involved in 15% of FH cases (birth prevalence, 3.0%). No cases of bilateral foveal hemorrhage were found. Fundus hemorrhages were more common in the left eye than the right. Fundus hemorrhages were most commonly optic nerve flame hemorrhages (48%) and white-centered retinal hemorrhages (30%). Retinal hemorrhages were found most frequently in all 4 quadrants (35%) and more often were multiple than solitary. Macular hemorrhages most often were intraretinal (40%). Among the risk factors examined in this study, vaginal delivery compared with cesarean section (odds ratio [OR], 9.34; 95% confidence interval [CI], 2.57-33.97) showed the greatest level of association with FH. Self-identified ethnicity as Hispanic or Latino showed a protective effect (OR, 0.43; 95% CI, 0.20-0.94). Other study factors were not significant. Fundus

  19. Competition from newborn granule cells does not drive axonal retraction of silenced old granule cells in the adult hippocampus

    Directory of Open Access Journals (Sweden)

    Carla M Lopez


    Full Text Available In the developing nervous system synaptic refinement, typified by the neuromuscular junction where supernumerary connections are eliminated by axon retraction leaving the postsynaptic target innervated by a single dominant input, critically regulates neuronal circuit formation. Whether such competition based pruning continues in established circuits of mature animals remains unknown. This question is particularly relevant in the context of adult neurogenesis where newborn cells must integrate into preexisting circuits, and thus, potentially compete with functionally mature synapses to gain access to their postsynaptic targets. The hippocampus plays an important role in memory formation/retrieval and the dentate gyrus subfield (DG exhibits continued neurogenesis into adulthood. Therefore, this region contains both mature granule cells (old GCs and immature recently born GCs that are generated throughout adult life (young GCs, providing a neurogenic niche model to examine the role of competition in synaptic refinement. Recent work from an independent group in developing animals indicated that embryonically/early postnatal generated GCs placed at a competitive disadvantage by selective expression of tetanus toxin (TeTX to prevent synaptic release rapidly retracted their axons, and that this retraction was driven by competition from newborn GCs lacking TeTX. In contrast, following 3-6 months of selective TeTX expression in old GCs of adult mice we did not observe any evidence of axon retraction. Indeed ultrastructural analyses indicated that the terminals of silenced GCs even maintained synaptic contact with their postsynaptic targets. Furthermore, we did not detect any significant differences in the electrophysiological properties between old GCs in control and TeTX conditions. Thus, our data demonstrate a remarkable stability in the face of a relatively prolonged period of altered synaptic competition between two populations of neurons within the

  20. Mobile Health in Maternal and Newborn Care: Fuzzy Logic

    Directory of Open Access Journals (Sweden)

    Shahirose Premji


    Full Text Available Whether mHealth improves maternal and newborn health outcomes remains uncertain as the response is perhaps not true or false but lies somewhere in between when considering unintended harmful consequences. Fuzzy logic, a mathematical approach to computing, extends the traditional binary “true or false” (one or zero to exemplify this notion of partial truths that lies between completely true and false. The commentary explores health, socio-ecological and environmental consequences–positive, neutral or negative. Of particular significance is the negative influence of mHealth on maternal care-behaviors, which can increase stress reactivity and vulnerability to stress-induced illness across the lifespan of the child and establish pathways for intergenerational transmission of behaviors. A mHealth “fingerprinting” approach is essential to monitor psychosocial, economic, cultural, environmental and physical impact of mHealth intervention and make evidence-informed decision(s about use of mHealth in maternal and newborn care.
