Prosecuting cases of abusive head trauma in Switzerland: a descriptive study of the impact of medical documentation and delay of reporting on judicial outcome.

Abusive head trauma (AHT) is a criminal offence that is prosecuted ex officio, following report to the police from physicians or child protection services. The aim of this study was to assess whether the judicial outcome (dismissal vs indictment) was influenced by the quality of the medical documentation and/or the time span between AHT diagnosis and reporting child abuse to the police. The cohort was divided in two groups: 13/23 dismissals (57%) and 10/23 indictments (43%). The diagnostic probability of the AHT cases was certain for both groups. Nonetheless, in fraction of dismissed cases, alternative explanations for the observed lesions seemed plausible to the public prosecutor. Legal files of only 3/12 dismissed cases had a forensic report, while 6/10 cases that were indicted included a forensic report. Further, the legal file of several dismissed cases entirely lacked medical documentation (3/12), which was not the cases for indicted cases. The period between AHT diagnosis and reporting to the police was not different for dismissals (29 ± 19 days) and indictments (7 ± 4 days) (p = 0.32). Physicians filed reports more rapidly (6 ± 1 days) compared to childhood protection service (70 ± 46 days) (p = 0.01) and that may increase the rate of indictments (9/18) compared to reporting via the childhood protection service (1/5). Despite diagnostic certainty, other causes for the lesions were considered as plausible alternative explanations to judicial professionals in several dismissed cases. These seemed to have less medical documentation and forensic evaluations. In addition, more rapid reporting to the police by physicians seems to increase the likelihood of indictments.

Incidence and Management of Neonatal Pneumothorax in a 10-Hospital Regional Perinatal Network in Switzerland: A Retrospective Observational Study.

OBJECTIVE: Pneumothorax (PTX) is a potentially life-threatening condition that affects neonates, with an incidence of 0.05 to 2%. Its management includes conservative treatment, chest tube (CT) drainage, and needle aspiration (NA). Aims were to evaluate the incidence of PTX in a 10-hospital perinatal network, its clinical characteristics and risk factors, and to compare the different treatment options. STUDY DESIGN: All neonates diagnosed with PTX and hospitalized in the network were included in this retrospective observational trial over a period of 30 months. Primary outcome was the incidence of PTX. Secondary outcomes were the treatment modality, the length of stay (LOS), and the number of chest X-rays. RESULTS: Among the 173 neonates included, the overall incidence of PTX was 0.56 per 100 births with a large range among the hospitals (0.12-1.24). Thirty-nine percent of pneumothoraces were treated conservatively, 41% by CT drainage, 13% by NA, and 7% by combined treatment. Failure rate was higher for NA (37%) than for CT drainage (9%). However, the number of X-rays was lower for patients treated by NA, with a median of 6 (interquartile range [IQR] 4-6.25), than by CT drainage, with a median of 9 (IQR 7-12). LOS was shorter for NA than for CT drainage, with a median of 2 (IQR 1-4.25) and 6 days (IQR 3-15), respectively. Complications, including apnea and urinary retention, occurred in 28% of patients managed with CT drainage, whereas none was observed with NA. CONCLUSION: High variability of PTX incidence was observed among the hospitals within the network, but these values correspond to the literature. NA showed to reduce the number of X-rays, the LOS, and complications compared with CT drainage, but it carries a high failure rate. This study helped provide a new decisional management algorithm to harmonize and improve PTX treatment within our network. KEY POINTS: · Neonatal PTX is a frequent pathology with a high incidence requiring urgent management.. · We report a large variability of PTX incidence between different hospitals of the same network.. · Needle aspiration carries higher failure rate, shorter hospital stay duration without complications reported..

Maternal childbirth-related posttraumatic stress symptoms, bonding, and infant development: a prospective study.

BACKGROUND: Childbirth-related posttraumatic stress symptoms (CB-PTSS) including general symptoms (GS, i.e., mainly negative cognitions and mood and hyperarousal symptoms) and birth-related symptoms (BRS, i.e., mostly re-experiencing and avoidance symptoms) may disrupt mother-infant bonding and infant development. This study investigated prospective and cross-sectional associations between maternal CB-PTSS and mother-infant bonding or infant development (language, motor, and cognitive). METHOD: We analysed secondary data of the control group of a randomised control trial (NCT03576586) with full-term French-speaking mother-infant dyads (n = 55). Maternal CB-PTSS and mother-infant bonding were assessed via questionnaires at six weeks (T1) and six months (T2) postpartum: PTSD Checklist for DSM-5 (PCL-5) and Mother-Infant Bonding Scale (MIBS). Infant development was assessed with the Bayley Scales of Infant Development at T2. Sociodemographic and medical data were collected from questionnaires and medical records. Bivariate and multivariate regression were used. RESULTS: Maternal total CB-PTSS score at T1 was associated with poorer bonding at T2 in the unadjusted model (B = 0.064, p = 0.043). In the adjusted model, cross-sectional associations were found at T1 between a higher total CB-PTSS score and poorer bonding (B = 0.134, p = 0.017) and between higher GS and poorer bonding (B = 0.306, p = 0.002). Higher BRS at T1 was associated with better infant cognitive development at T2 in the unadjusted model (B = 0.748, p = 0.026). CONCLUSIONS: Results suggest that CB-PTSS were associated with mother-infant bonding difficulties, while CB-PTSS were not significantly associated with infant development. Additional studies are needed to increase our understanding of the intergenerational consequences of perinatal trauma.

[Access to donor human milk in Switzerland and CHUV's first human milk bank in Romandy : issues and perspectives]. / Pédiatrie - Accès au lait de donneuses en Suisse et création de la première banque de lait maternel romande au CHUV : enjeux et perspectives.

Mother's own milk (MOM) is ideal for infant growth and health. When MOM is unavailable, donor human milk (DHM), rather than infant formula, is recommended for at-risk, preterm or sick neonates (NN), in view of its protective effects. Human milk banks (HMB) collect, secure, process and distribute DHM. In Switzerland, there is insufficient and unequal access to DHM in the absence of a national policy framework. With the support of the State of Vaud, the CHUV and the Interregional Blood Transfusion of the Swiss Red Cross will open the first HMB in Romandy in 2022. This HMB offers an innovative system in Switzerland, based on complementary expertise, in order to guarantee the quality and safety of DHM and to support the promotion of breastfeeding and human milk donation.

Le lait maternel (LM) est idéal pour la croissance et la santé des nourrissons. En l'absence de LM, le lait de donneuses (LD) est préférable au lait artificiel pour les nouveau-nés (NN) à risques, prématurés ou présentant certaines pathologies, au vu de ses effets protecteurs. Les banques de lait (BL) collectent, sécurisent, traitent et distribuent le LD. Il existe en Suisse une insuffisance et une inégalité d'accès au LD, faute de cadre national. Avec le soutien de l'État de Vaud, le CHUV et la Transfusion interrégionale de la Croix-Rouge suisse ouvriront en 2022 la première BL romande. Cette BL propose un système novateur en Suisse, fondé sur une complémentarité d'expertises, afin d'optimiser la qualité et la sécurité du LD et de soutenir la promotion de l'allaitement et du don.

A population pharmacokinetic model for escitalopram and its major metabolite in depressive patients during the perinatal period: Prediction of infant drug exposure through breast milk.

BACKGROUND AND OBJECTIVES: Escitalopram (SCIT) is frequently prescribed to breastfeeding women. Available information on SCIT excretion into breast milk is based on heterogeneous and incomplete data. A population pharmacokinetic model that aimed to better characterize maternal and infant exposure to SCIT and its metabolite was developed. METHODS: The study population was composed of women treated by SCIT or racemic citalopram and enrolled in the multicenter prospective cohort study SSRI-Breast Milk study (ClinicalTrial.gov NCT01796132). A joint structural model was first built for SCIT and S-desmethylcitalopram (SDCIT) in plasma using NONMEM and the milk-to-plasma ratio (MPR) was estimated by adding the drug breast milk concentrations. The effect of different influential covariates was tested and the average drug exposure with variability through breastfeeding was predicted under various conditions by simulation. RESULTS: The study enrolled 33 patients treated with SCIT or racemic citalopram who provided 80 blood and 104 milk samples. Mean MPR for both parent drug and metabolite was 1.9. Increased milk fat content was significantly associated with an increased drug transfer into breast milk (+28% for SCIT and +18% for SDCIT when fat amount doubles from 3.1 to 6.2 g/100 mL). Simulations suggested that an exclusively breastfed infant would ingest daily through breast milk 3.3% of the weight-adjusted maternal SCIT dose on average. CONCLUSION: The moderate between-subject variability in milk concentration of SCIT and the limited exposure to escitalopram through breast milk observed provide reassurance for treated mothers of breastfed healthy infants.

Incident reports versus direct observation to identify medication errors and risk factors in hospitalised newborns.

Newborns are often exposed to medication errors in hospitals. Identification and understanding the causes and risk factors associated with medication errors will help to improve the effectiveness of medication. We sought to compare voluntary incident reports and direct observation in the identification of medication errors. We also identified corresponding risk factors in order to establish measures to prevent medication errors. Medication errors identified by a clinical pharmacist and those recorded in our incident reporting system by caregivers were analysed. Main outcomes were rates, type and severity of medication error, and other variables related to medication errors. Ultimately, 383 medication errors were identified by the clinical pharmacist, and two medication errors were declared by caregivers. Prescription errors accounted for 38.4%, preparation errors for 16.2%, and administration errors for 45.4%. The two variables significantly related to the occurrence of medication errors were gestational age < 32.0 weeks (p = 0.04) and the number of drugs prescribed (p < 0.01).Conclusion: Caregivers underreported the true rate of medication errors. Most medication errors were caused by inattention and could have been limited by simplifying the medication process. Risk of medication errors is increased in newborns < 32.0 weeks and increases with the number of drugs prescribed to each patient. What is Known: • Newborns in hospitals are particularly susceptible to medication errors. • Identification and understanding the reasons for medication errors should help us to establish preventive measures to reduce the occurrence of such errors. What is New: • Direct observation of the medication process, though time consuming, is essential to accurately assess the frequency of medication errors, which are underreported by caregivers. Most medication errors are caused by inattention and could be limited by simplifying the medication process. • The risk of medication errors was significantly increased in very preterm newborns (< 32 weeks) and when the number of prescription per patient increased.

Impact of Early Nutritional Intake on Preterm Brain: A Magnetic Resonance Imaging Study.

OBJECTIVES: To investigate the association between early nutritional intake and brain development assessed by magnetic resonance imaging (MRI). STUDY DESIGN: A cohort of neonates born at ≤30 weeks gestational age underwent MRI at term equivalent age. Brain maturation and injury were assessed using the Kidokoro score. Two groups were defined by severity of the scores. The associations between macronutrients intake during the first 2 weeks of life, clinical factors, and imaging scores were analyzed using logistic regression. RESULTS: MRI scores from group 1 patients (n = 27) were normal to mildly abnormal (0-5). Group 2 (n = 15) had more abnormal scores (6-12). The median gestational ages (IQR) were 27.4 (1.9) weeks in group 1 and 27.0 (2.9) weeks in group 2, with birth weights of 900 (318) g (group 1) and 844 (293) g (group 2). In group 2, energy, lipid, and carbohydrate intake were significantly lower than in group 1. Group 2 also showed higher rates of sepsis and clinical risk scores than group 1. After adjustments in bivariate models, higher energy and lipid intake remained significantly associated with improved scores on MRI. This association was stronger for the gray matter component of the score. CONCLUSIONS: Higher energy and lipid intake during the first 2 weeks after birth was associated with a lower incidence of brain lesions and dysmaturation at term equivalent age in preterm neonates.

[Novelties 2016 in pediatrics]. / Pédiatrie.

Nutrition is central in pediatric care : essential for growth and development, it plays also a role in the prevention of many diseases.Even if breastfeeding is highly recommended, its implementation may be difficult in particular for premature and ill newborns. The creation of a specific unit for breastfeeding support in neonatology allows to help mothers willing to nurse and to improve the rate of breastfeeding for these vulnerable infants.Eating disorders represent an important challenge for patient care. Early detection and rapid management of anorexia is essential for the prognosis. This article describes the challenges and the practical process underlying the development of a practical guideline to manage children and adolescents hospitalized for anorexia.

La nutrition est un thème central en pédiatrie : essentielle pour la croissance et le développement de l'enfant, elle joue également un rôle dans la prévention de nombreuses maladies.Bien que fortement recommandée, la mise en place de l'allaitement peut être difficile en particulier chez les nouveau-nés prématurés ou malades. La création d'une unité de soutien à l'allaitement en néonatologie a permis d'offrir un soutien aux mères souhaitant allaiter et d'améliorer le taux de lactation. Les troubles du comportement alimentaire représentent un important challenge de prise en charge. Une détection et une prise en charge rapide de l'anorexie sont essentielles pour le pronostic. Cet article décrit les enjeux et le processus parcouru pour élaborer un guide de prise en charge des enfants et adolescent(e)s hospitalisé(e)s pour une anorexie.

A bundle with a preformatted medical order sheet and an introductory course to reduce prescription errors in neonates.

The objective of this study was to assess whether the introduction of a new preformatted medical order sheet coupled with an introductory course affected prescription quality and the frequency of errors during the prescription stage in a neonatal intensive care unit (NICU). Two-phase observational study consisting of two consecutive 4-month phases: pre-intervention (phase 0) and post-intervention (phase I) conducted in an 11-bed NICU in a Swiss university hospital. Interventions consisted of the introduction of a new preformatted medical order sheet with explicit information supplied, coupled with a staff introductory course on appropriate prescription and medication errors. The main outcomes measured were formal aspects of prescription and frequency and nature of prescription errors. Eighty-three and 81 patients were included in phase 0 and phase I, respectively. A total of 505 handwritten prescriptions in phase 0 and 525 in phase I were analysed. The rate of prescription errors decreased significantly from 28.9% in phase 0 to 13.5% in phase I (p < 0.05). Compared with phase 0, dose errors, name confusion and errors in frequency and rate of drug administration decreased in phase I, from 5.4 to 2.7% (p < 0.05), 5.9 to 0.2% (p < 0.05), 3.6 to 0.2% (p < 0.05), and 4.7 to 2.1% (p < 0.05), respectively. The rate of incomplete and ambiguous prescriptions decreased from 44.2 to 25.7 and 8.5 to 3.2% (p < 0.05), respectively. CONCLUSION: Inexpensive and simple interventions can improve the intelligibility of prescriptions and reduce medication errors. WHAT IS KNOWN: Medication errors are frequent in NICUs and prescription is one of the most critical steps. CPOE reduce prescription errors, but their implementation is not available everywhere. WHAT IS NEW: Preformatted medical order sheet coupled with an introductory course decrease medication errors in a NICU. Preformatted medical order sheet is an inexpensive and readily implemented alternative to CPOE.

Improving Maternal Mental Health Following Preterm Birth Using an Expressive Writing Intervention: A Randomized Controlled Trial.

Evaluations of evidence-based, easily accessible, psychological interventions to improve maternal mental health following very preterm birth are scarce. This study investigated the efficacy and acceptability of the expressive writing paradigm for mothers of very preterm infants. The level of maternal posttraumatic stress and depressive symptoms was the primary outcome. Participants were 67 mothers of very preterm babies who were randomly allocated into the intervention (expressive writing; n = 33) or control group (treatment-as-usual; n = 32) when their infant was aged 3 months (corrected age, CA). Measurements were taken at 3 months (pre-intervention), 4 months (post-intervention), and 6 months CA (follow-up). Results showed reduced maternal posttraumatic stress (d = 0.42), depressive symptoms (d = 0.67), and an improved mental health status (d = 1.20) in the intervention group, which were maintained at follow-up. Expressive writing is a brief, cost-effective, and acceptable therapeutic approach that could be offered as part of the NICU care.

[SSRI antidepressant use during pregnancy and the assessment of the risk-benefit ratio]. / Bon usage des antidépresseurs ISRS durant la grossesse--le défi de l'évaluation de la balance bénéfice-risque.

Studies report that between 6 and 13% of women experience symptoms of depression during pregnancy and the postpartum period. The abundant data available make selective serotonin reuptake inhibitors (SSRIs) the first line treatment in pregnancy when a pharmacological treatment is required. Risks associated with the use of SSRIs during pregnancy are limited (moderate effect size) and are often not distinguishable from those inherent to the mother's disease. Yet, several questions regarding the SSRI safety profile for the unborn child are still under debate or require additional epidemiological data. The decision of SSRI use during pregnancy needs an individual evaluation of the risk-benefit balance.

Fetal sex and the relative reactivity of human umbilical vein and arteries are key determinants in potential beneficial effects of phosphodiesterase inhibitors.

Intrauterine growth restriction (IUGR) is a common complication of pregnancy. We previously demonstrated that IUGR is associated with an impaired nitric oxide (NO)-induced relaxation in the human umbilical vein (HUV) of growth-restricted females compared to appropriate for gestational age (AGA) newborns. We found that phosphodiesterase (PDE) inhibition improved NO-induced relaxation in HUV, suggesting that PDEs could represent promising targets for therapeutic intervention. This study aimed to investigate the effects of PDE inhibition on human umbilical arteries (HUAs) compared to HUV. Umbilical vessels were collected in IUGR and AGA term newborns. NO-induced relaxation was studied using isolated vessel tension experiments in the presence or absence of the nonspecific PDE inhibitor 3-isobutyl-1-methylxanthine (IBMX). PDE1B, PDE1C, PDE3A, PDE4B, and PDE5A were investigated by Western blot. NO-induced vasodilation was similar between IUGR and AGA HUAs. In HUAs precontracted with serotonin, IBMX enhanced NO-induced relaxation only in IUGR females, whereas in HUV IBMX increased NO-induced relaxation in all groups except IUGR males. In umbilical vessels preconstricted with the thromboxane A2 analog U46619, IBMX improved NO-induced relaxation in all groups to a greater extent in HUV than HUAs. However, the PDE protein content was higher in HUAs than HUV in all study groups. Therefore, the effects of PDE inhibition depend on the presence of IUGR, fetal sex, vessel type, and vasoconstrictors implicated. Despite a higher PDE protein content, HUAs are less sensitive to IBMX than HUV, which could lead to adverse effects of PDE inhibition in vivo by impairment of the fetoplacental hemodynamics.NEW & NOTEWORTHY The effects of phosphodiesterase inhibition on the umbilical circulation depend on the presence of intrauterine growth restriction, the fetal sex, vessel type, and vasoconstrictors implicated. The human umbilical vascular tone regulation is complex and depends on the amount and activity of specific proteins but also probably on the subcellular organization mediating protein interactions. Therefore, therapeutic interventions using phosphodiesterase inhibitors to improve the placental-fetal circulation should consider fetal sex and both umbilical vein and artery reactivity.

Joint observation in NICU (JOIN): A randomized controlled trial testing an early, one-session intervention during preterm care to improve perceived maternal self-efficacy and other mental health outcomes.

BACKGROUND: Parents of preterm infants in the Neonatal Intensive Care Unit (NICU) environment may experience psychological distress, decreased perceived self-efficacy, and/or difficulties in establishing an adaptive parent-infant relationship. Early developmental care interventions to support the parental role and infant development are essential and their impact can be assessed by an improvement of parental self-efficacy perception. The aims were to assess the effects of an early intervention provided in the NICU (the Joint Observation) on maternal perceived self-efficacy compared to controls (primary outcome) and to compare maternal mental health measures (perceived stress, anxiety, and depression), perception of the parent-infant relationship, and maternal responsiveness (secondary outcomes). METHODS: This study was a monocentric randomized controlled trial registered in clinicatrials.gov (NCT02736136), which aimed at testing a behavioural intervention compared with treatment-as-usual. Mothers of preterm neonates born 28 to 32 6/7 weeks gestation were randomly allocated to either the intervention or the control groups. Outcome measures consisted of self-report questionnaires completed by the mothers at 1 and 6 months after enrollment and assessing perceived self-efficacy, mental health, perception of the parent-infant relationship and responsiveness, as well as satisfaction with the intervention. RESULTS: No statistically significant group effects were observed for perceived maternal self-efficacy or the secondary outcomes. Over time, perceived maternal self-efficacy increased for mothers in both groups, while anxiety and depression symptoms decreased. High satisfaction with the intervention was reported. CONCLUSIONS: The joint observation was not associated with improved perceived maternal self-efficacy or other mental health outcomes, but may constitute an additional supportive measure offered to parents in a vulnerable situation during the NICU stay.

Phthalates in the NICU: is it safe?

AIMS: As growing concerns exist regarding phthalate exposure, which could be teratogenic, carcinogenic or induce reproductive toxicity, we aimed to review the evidence of the risks due to the use of medical devices containing di(2-ethylhexyl)phthalate in hospitalized neonates. METHODS: We reviewed the literature, searching through medical literature databases (Pubmed, MEDLINE, EBM reviews, Cochrane database, Embase and Google Scholar) using the following keywords: phthalate, di(2-ethylhexyl)phthalate, newborn and neonate. RESULTS: We identified several associations with short and long term health dangers, mainly subfertility, broncho-pulmonary dysplasia, necrotising enterocolitis, parenteral nutrition associated cholestasis and neuro-developmental disorders. These data are based mainly on animal or observational human studies. CONCLUSION: Clinicians must be aware of the potential risks due to phthalate exposure in the NICU. Di(2-ethylhexyl)phthalate containing materials should be identified and alternative devices should be considered. There is a need to improve knowledge in this area.

Fetal programming of pulmonary vascular dysfunction in mice: role of epigenetic mechanisms.

Insults during the fetal period predispose the offspring to systemic cardiovascular disease, but little is known about the pulmonary circulation and the underlying mechanisms. Maternal undernutrition during pregnancy may represent a model to investigate underlying mechanisms, because it is associated with systemic vascular dysfunction in the offspring in animals and humans. In rats, restrictive diet during pregnancy (RDP) increases oxidative stress in the placenta. Oxygen species are known to induce epigenetic alterations and may cross the placental barrier. We hypothesized that RDP in mice induces pulmonary vascular dysfunction in the offspring that is related to an epigenetic mechanism. To test this hypothesis, we assessed pulmonary vascular function and lung DNA methylation in offspring of RDP and in control mice at the end of a 2-wk exposure to hypoxia. We found that endothelium-dependent pulmonary artery vasodilation in vitro was impaired and hypoxia-induced pulmonary hypertension and right ventricular hypertrophy in vivo were exaggerated in offspring of RDP. This pulmonary vascular dysfunction was associated with altered lung DNA methylation. Administration of the histone deacetylase inhibitors butyrate and trichostatin A to offspring of RDP normalized pulmonary DNA methylation and vascular function. Finally, administration of the nitroxide Tempol to the mother during RDP prevented vascular dysfunction and dysmethylation in the offspring. These findings demonstrate that in mice undernutrition during gestation induces pulmonary vascular dysfunction in the offspring by an epigenetic mechanism. A similar mechanism may be involved in the fetal programming of vascular dysfunction in humans.

Perinatal hypoxia enhances cyclic adenosine monophosphate-mediated BKCa channel activation in adult murine pulmonary artery.

Exposure to perinatal hypoxia results in alteration of the adult pulmonary circulation, which is linked among others to alterations in K(+) channels in pulmonary artery (PA) smooth muscle cells. In particular, large conductance Ca(2+)-activated K(+) (BK(Ca)) channels protein expression and activity were increased in adult PA from mice born in hypoxia compared with controls. We evaluated long-term effects of perinatal hypoxia on the cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) pathway-mediated activation of BK(Ca) channels, using isoproterenol, forskolin, and dibutyryl-cAMP. Whole-cell outward current was higher in pulmonary artery smooth muscle cells from mice born in hypoxia compared with controls. Spontaneous transient outward currents, representative of BK(Ca) activity, were present in a greater proportion in pulmonary artery smooth muscle cells of mice born in hypoxia than in controls. Agonists induced a greater relaxation in PA of mice born in hypoxia compared with controls, and BK(Ca) channels contributed more to the cAMP/PKA-mediated relaxation in case of perinatal hypoxia. In summary, perinatal hypoxia enhanced cAMP-mediated BK(Ca) channels activation in adult murine PA, suggesting that this pathway could be a potential target for modulating adult pulmonary vascular tone after perinatal hypoxia.

Vitamins and carotenoids in human milk delivering preterm and term infants: Implications for preterm nutrient requirements and human milk fortification strategies.

Differences in vitamin and carotenoids content of human milk (HM) produced for infants born at term and preterm is poorly understood. In this study, HM was collected weekly for four and two months post-partum for preterm and term groups, respectively. Nutrients of interest, from single full breast expressions were measured by liquid chromatography coupled with mass spectrometry. Microbiological assay was employed for vitamin B12. When compared at equivalent post-partum age, vitamins B1, B2, B6, and B9 were significantly higher in preterm than in term HM, but only during the first two weeks. No significant differences were observed for A, E, B3 and B12 between groups. Lycopene was the only carotenoid exhibiting a significant higher concentration in term than in preterm HM between weeks 1 and 4 post-partum. When compared at equivalent post-menstrual age, preterm milk was significantly higher for vitamins B1, B2, B3, B6 and B9 and lower levels of vitamins A, E, ß-carotene, ß-cryptoxanthin, lutein, zeaxanthin and lycopene compared to their term counterparts. These results suggest that preterm breastfed infants at term equivalent age may receive lower amounts of these micronutrients than breast-fed term neonates, possibly highlighting the need to supplement or fortify their nutritional intake with vitamins and carotenoids.

Intrauterine growth restriction is associated with sex-specific alterations in the nitric oxide/cyclic GMP relaxing pathway in the human umbilical vein.

INTRODUCTION: Intrauterine growth restriction (IUGR) is a leading cause of perinatal mortality and morbidity, and is linked to an increased risk to develop chronic diseases in adulthood. We previously demonstrated that IUGR is associated, in female neonates, with a decreased nitric oxide (NO)-induced relaxation of the umbilical vein (UV). The present study aimed to investigate the contribution of the smooth muscle components of the NO/cyclic GMP (cGMP) pathway to this alteration. METHODS: UVs were collected in growth-restricted or appropriate for gestational age (AGA) human term newborns. Soluble guanylyl cyclase (sGC) and cGMP-dependent protein kinase (PKG) were studied by Western blot, cGMP production by ELISA and cyclic nucleotide phosphodiesterases (PDEs) activity using a colorimetric assay. Contribution of PDEs was evaluated using the non-specific PDEs inhibitor 3-isobutyl-1-methylxanthine (IBMX) in isolated vessel tension studies. RESULTS: NO-induced relaxation was reduced in IUGR females despite increased sGC protein and activity, and some increase in PKG protein compared to AGA. In males, no significant difference was observed between both groups. In the presence of IBMX, NO-stimulated cGMP production was significantly higher in IUGR than AGA females. Pre-incubation with IBMX significantly improved NO-induced relaxation in all groups and abolished the difference between IUGR and AGA females. CONCLUSION: IUGR is associated with sex-specific alterations in the UV's smooth muscle. The impaired NO-induced relaxation observed in growth-restricted females is linked to an imbalance in the NO/cGMP pathway. The beneficial effects of IBMX suggest that PDEs are implicated in such alteration and they could represent promising targets for therapeutic intervention.

Early neurological impairment and severe anemia in a newborn with Pearson syndrome.

BACKGROUND: Pearson marrow-pancreas syndrome (PS) is usually a fatal mitochondrial disease, mostly diagnosed during infancy or postmortem. PS is caused by the deletions or duplications of mitochondrial DNA (mtDNA). The tissue distribution and relative proportions of expressed abnormal mtDNA determine the phenotype and the clinical course. MATERIALS AND METHODS: We describe the case of a term baby boy who was diagnosed with PS early in the neonatal period due to severe aregenerative anemia and persistent lactic acidosis. RESULTS: His neurological examination was abnormal since birth. Brain magnetic resonance imaging (MRI) at term was abnormal, indicating that mitochondrial encephalopathy in PS can be already manifested in the neonatal period. To our knowledge, neonatal encephalopathy in PS has not been previously described. CONCLUSION: PS is a rare condition diagnosed in the newborn. It should be suspected in the presence of severe anemia and persistent lactic acidosis, and may manifest with early encephalopathy.

Joint observation in NICU (JOIN): study protocol of a clinical randomised controlled trial examining an early intervention during preterm care.

INTRODUCTION: Preterm birth may generate significant distress among the parents, who often present with difficulties in appropriating their parental role. Parental stress and low perceived parental self-efficacy may interfere with the infant's socioemotional and cognitive development, particularly through disrupted parent-infant interactions. Perceived parental self-efficacy represents the belief of efficacy in caring for one's own infant and successful incarnation of the parental role, as well as the perception of one's own abilities to complete a specified task. Interventions to support parental role, as well as infant development, are needed, and parental self-efficacy represents a useful indicator to measure the effects of such early interventions. METHODS AND ANALYSIS: This study protocol describes a randomised controlled trial that will test an early intervention in the neonatal intensive care unit (NICU) (JOIN: Joint Observation In Neonatology) carried out by an interdisciplinary staff team. Mothers of preterm neonates born between 28 and 32 6/7 weeks of gestational age are eligible for the study. The intervention consists of a videotaped observation by a clinical child psychologist or child psychiatrist and a study nurse of a period of care delivered to the neonate by the mother and a NICU nurse. The care procedure is followed by an interactive video guidance intended to demonstrate the neonate's abilities and resources to his parents. The primary outcome will be the difference in the perceived maternal self-efficacy between the intervention and control groups assessed by self-report questionnaires. Secondary outcomes will be maternal mental health, the perception of the parent- infant relationship, maternal responsiveness and the neurodevelopment of the infant at 6 months corrected age. ETHICS AND DISSEMINATION: Ethical approval was granted by the Human Research Ethics Committee of the Canton de Vaud (study number 496/12). Results from this study will be disseminated at national and international conferences, and in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT02736136, Pre-results.
