Risk stratification to improve Pediatric Early Warning Systems: it is all about the context

Early recognition of critically ill patients is of paramount importance to reduce pediatric mortality and morbidity. We created a risk stratification system combining vital parameters and predefined risk factors aimed at reducing the risk of unrecognized clinical deterioration compared with conventional Pediatric Early Warning Systems (PEWS). This single-center retrospective case cohort study included infants (gestational age ≥ 37 weeks) to adolescents (aged <18 years) with unplanned pediatric intensive care unit (PICU) admission between April 01, 2014, and February 28, 2018. The sensitivity in the 24 h prior to endpoint of the Pediatric Risk Evaluation and Stratification System (PRESS) was compared with that of the conventional PEWS and calculated as the proportion of study patients who received a high-risk score. Seventy-four PICU admissions were included. PRESS and PEWS sensitivities at 2 h prior to endpoint were 0.70 (95%CI 0.59 to 0.80) and 0.30 (95%CI 0.20 to 0.42) respectively (p < 0.001). Excluding patients with seizures, PRESS sensitivity increased to 0.75 (95%CI 0.64 to 0.85). Forty-nine patients (66%) scored positive on at least one high-risk factor, and “worried sign” was scored in 31 patients (42%).

Conclusion: Risk stratification seems advantageous for a faster detection of clinical deterioration, providing opportunity for earlier intervention.

An exploratory survey on the state of training in adolescent medicine and health in 36 European countries

The development of adolescent health and medicine as a medical discipline lags behind in Europe compared with other regions of the world. This study aims to evaluate the structure and content of adolescent medicine and health training curricula for medical students, paediatricians, and other primary care physicians in the European region. A questionnaire survey was sent by e-mail to experts in the field from 36 European countries, addressing the content of adolescent health issues. Data was obtained from all 36 countries. At the undergraduate level, seven countries reported some mandatory stand-alone teaching (sessions dealing specifically with adolescents), while seven countries reported optional stand-alone teaching. In only 7 out of 36 countries were issues critical to adolescents covered as stand-alone sessions. At the postgraduate level, 15 countries delivered stand-alone mandatory training sessions to primary, secondary, or tertiary care paediatricians, covering most of the five critical areas listed in the questionnaire. In another 13 countries, such sessions were not mandatory and were inexistent in eight of them. The coverage among school physicians was similar but was much lower among general practitioners.

Conclusion: Paediatric associations and academic institutions should advocate for a better coverage of adolescent health and medicine in the training curricula of health care providers.

Can intussusceptions of small bowel and colon be transient? A prospective study

We performed a prospective study to explore a diagnosis and treatment protocol of transient intussusception in children (TIC). Totally, 143 children with intussusception who met the inclusion criteria were firstly divided into intussusception involving only the small bowel and intussusception involving the colon group. And in each group, they were further divided into short-segment (≤ 3.0 cm) and long-segment (> 3.0 cm) groups according to the length of intussusception. After a period of conservative treatment, the incidence of TIC, the incidence of surgery, and recurrence were collected and analyzed. Finally, we found that the incidence of TIC in the short-segment group of small bowel intussusception (96.29%) was significantly higher than that in other groups (P ≤ 0.001). Besides, the incidence of surgery and recurrence in this group was relatively low too. Therefore, we summarized the inclusion criteria and treatments to the short-segment group of small bowel intussusception as the suggested protocol to TIC.

Conclusion: For cases of small bowel intussusception with no identified pathologic lead point, a short duration of symptoms, a length of ≤ 3.0 cm, a relatively abundant vascular flow signal, and a stable general condition, the spontaneous reduction could be expected and a period of conservative treatment with careful monitoring is recommended.

Parental and child factors associated with inhalant and food allergy in a population-based prospective cohort study: the Generation R Study

The prevalence of allergic diseases in children is markedly increasing to epidemic proportions. The aim of this study is to describe the presence and examine associated parental and child characteristics of allergic sensitization and physician-diagnosed allergy in Dutch children at age 10 years. This study among 5471 children was performed in a population-based prospective cohort from fetal life onwards. Allergic sensitization was measured by skin prick tests. Physician-diagnosed allergy and parental and child characteristics were collected by questionnaires. In children aged 10 years, inhalant and food allergic sensitization was present in 32.2% and 7.1%, and physician-diagnosed inhalant and food allergy in 12.4% and 2.3%. Maternal and paternal history of allergy, eczema or asthma was associated with increased risks of physician-diagnosed inhalant allergy (aOR (95% CI) 1.44 (1.23–1.70) and 1.59 (1.30–1.94), respectively), but not with food allergy. Asthma and eczema ever at age 10 years were associated with increased risks of physician-diagnosed inhalant allergy (4.60 (3.55–5.96) and 2.42 (1.94–3.03), respectively). Eczema ever at age 10 years was associated with an increased risk of physician-diagnosed food allergy (5.78, 3.04–9.52), with the highest risk of cashew (7.36, 3.20–16.94) and peanut (5.58, 3.08–10.10) food allergy.

Conclusions: We found strong effects of parental history of allergy, eczema or asthma on the presence of physician-diagnosed inhalant allergy in children at age 10 years. Eczema ever at age 10 years was a strong risk factor for the development of physician-diagnosed inhalant and food allergy.

Genotype phenotype correlation in a pediatric population with antithrombin deficiency

Inherited antithrombin (AT) deficiency is a rare autosomal dominant disorder, caused by mutations in the AT gene (SERPINC1). Considering that the genotype phenotype relationship in AT deficiency patients remains unclear, especially in pediatric patients, the aim of our study was to evaluate genotype phenotype correlation in a Serbian pediatric population. A retrospective cohort study included 19 children younger than 18 years, from 15 Serbian families, with newly diagnosed AT deficiency. In 21% of the recruited families, mutations affecting exon 4, 5, and 6 of the SERPINC1 gene that causes type I AT deficiency were detected. In the remaining families, the mutation in exon 2 causing type II HBS (AT Budapest 3) was found. Thrombosis events were observed in 1 (33%) of those with type I, 11 (85%) of those with AT Budapest 3 in the homozygous respectively, and 1(33%) in the heterozygous form. Recurrent thrombosis was observed only in AT Budapest 3 in the homozygous form, in 27% during initial treatment of the first thrombotic event. Abdominal venous thrombosis and arterial ischemic stroke, observed in almost half of the children from the group with AT Budapest 3 in the homozygous form, were unprovoked in all cases.

Conclusion: Type II HBS (AT Budapest 3) in the homozygous form is a strong risk factor for arterial and venous thrombosis in pediatric patients.

Cord blood interleukin-10 levels are increased in preterm newborns

Cell-mediated immunosuppression due to interleukin (IL)-10 may contribute to normal pregnancy. By contrast, delivery is associated with a predominance of T-helper-1 (Th1) cytokines (IL-12, interferon-γ) and might be regarded as a graft rejection process. The aim of the study was to assess IL-10 and IL-12 levels in cord blood samples from newborns and their normal mothers in relation to the gestational age and type of delivery. Cord blood and serum samples were obtained from 31 term newborns (gestational age 38–42 weeks) and 40 preterm newborns (mean gestational age 32 weeks). Serum samples were obtained from 26 mothers of term newborns at birth. There were 18 term and preterm infants born by caesarean section. Measurements of IL-10 and IL-12 levels by ELISA were repeated in mothers 15 days after delivery and in 11 preterm infants (median 14 days of age). Cord blood IL-10 levels were significantly higher in preterm than in term newborns (median 17.0 versus 3.2 pg/ml, P = 0.0001), but were similar to term newborns and paired mothers (2.2 versus 1.0 pg/ml). Term and preterm newborns also showed similar cord blood IL-12 levels (median 349 versus 320 pg/ml), and these levels were significantly higher when compared to their paired mothers (median 14.5 pg/ml, P = 0.0003). Cord blood IL-10 levels showed a significant inverse correlation with gestational age (P = 0.0001). When preterm infants, at several weeks post-delivery, were compared to gestational age matched newborns, their IL-10 levels were similar (median 8.3 pg/ml) whereas IL-12 levels were clearly lower(147 pg/ml; P = 0.0007). The type of delivery (vaginal versus caesarean) did not influence cord blood IL-10 and IL-12 results. Conclusion Cord blood IL-10 levels are increased in preterm newborns and may be due to the immunosuppression occurring during pregnancy and to fetal immaturity because these levels are inversely correlated with gestational age.

Neonates presenting with temperature symptoms: Role in the diagnosis of early onset sepsis

Background: In this study, we aimed to evaluate the role of fever, hypothermia, and temperature instability in term and preterm newborns during the first 3 days of life and to identify risk factors for early onset sepsis (EOS) among newborns presenting with these temperature symptoms. Methods: In this retrospective cohort study set in our level III neonatal intensive care unit, we included all newborns hospitalized within the first 24 h of life from 2004 to 2007. Results: Of 851 newborns, 127 presented with temperature symptoms during the first 3 days of life (15%): 69 had fever, 69 had hypothermia, and 55 had temperature instability (8%, 8%, and 6%, respectively). Of 127 newborns presenting with temperature symptoms, 14 had culture‐proven EOS/pneumonia (33% of all 42 newborns with culture‐proven EOS/pneumonia), 67 had clinical EOS (30% of all 209 newborns with clinical EOS) and 46 were EOS‐negative (8% of all 600 EOS‐negatives). Factors associated with culture‐proven EOS/pneumonia in newborns presenting with temperature symptoms were maternal fever (P= 0.009), chorioamnionitis (P < 0.001), antibiotic therapy of the mother (P= 0.04), poor skin color (P= 0.001) and syndrome of persistent fetal circulation (P= 0.01). Conclusions: Every seventh newborn hospitalized at our neonatal intensive care unit developed fever, hypothermia and/or temperature instability during the first 3 days of life. Two‐thirds of them had culture‐proven or clinical sepsis. Temperature symptoms were rarely observed in EOS‐negative newborns (8%) but despite low sensitivity, were highly specific for bacterial infection in preterm and term newborns.     

Exploring the olfactory environment of premature newborns: a French survey of health care and cleaning products used in neonatal units

Aim: To assess the main determinants of the newborn’s nosocomial olfactory environment. Methods: An electronic questionnaire was sent to 99 neonatal units in France. Senior nurses and/or physicians described the nature and use of skin care products (e.g. umbilical cord and skin disinfectants, adhesive removers), lubrications used for tubes positioning, disinfectants used to clean materials, hand hygiene products (e.g. alcohol‐based hand rubs, soaps) and newborns’ bath. Results: Nine groups of products and 76 distinct commercial preparations were identified. Depending on their level of respiratory support, preterm newborns were estimated to be exposed to nosocomial odours (NO) an average of 1320–1800 times during their first month of life. During their whole hospital stay, newborns of 28 and 32 weeks of gestational age could be exposed to NOs products an average of 3448 and 2024 times, respectively. The use of these products varied among medical centres. Newborns were most frequently exposed to the odour of aqueous alcoholic solutions. Conclusions: Vulnerable preterm infants are daily exposed to multiple NOs most of them be considered as irritant for the nose. Minimizing infants’ exposure to them would be beneficial. Future studies should describe the exact olfactory properties of the products considered essential for infant care and should assess their effects on the infant’s well‐being and development.     

Natural killer cell cytotoxicity is deficient in newborns with sepsis and recurrent infections

 We investigated natural killer (NK) cell cytotoxicity in healthy preterm and full-term newborns in comparison to adults, to elucidate the possible role of delivery mode in influencing the NK activity and to evaluate the NK activity in severe neonatal pathological conditions such as bacterial sepsis and recurrent infections. NK cell cytotoxicity was investigated using a 4 h ⁵¹Cr release assay with K562 cells as targets expressed as percentage kill in the following study groups: full-term normal spontaneous vaginal delivery (n=55), full-term caesarean section (n=51), preterm normal spontaneous vaginal delivery (n=34), preterm caesarean section (n=28), bacterial sepsis (n=15), recurrent neonatal infections (n=8) and healthy adults aged between 22–42 years (n=89). NK activity for the normal newborns was determined in paired cord and 2–4 day-old neonate blood. The NK cell cytotoxicity in healthy newborns was significantly lower than in adults (P < 0.01). Prematurity was associated with a significant decrease in NK cell activity compared to full-term neonates (P < 0.05). The mode of delivery did not influence the NK cytotoxicity. In sepsis and recurrent infections, a dramatic decrease in NK cell cytotoxicity was seen related to healthy newborns (P < 0.01). Conclusion Natural killer cell cytotoxicity is deficient in both neonatal sepsis and recurrent infections. Received: 30 August 2000 and in revised form: 9 January 2001 / Accepted: 22 March 2001

Randomized trial with soaps - what happens to a newborn baby's skin?

ObjectiveEvaluate the effectiveness of a children's soap with physiological pH in maintaining cutaneous pH and moisture of the newborn (NB)’s skin after the first bath.MethodsRandomized, controlled and double-blind clinical trial in a rooming-in of a tertiary maternity hospital in southern Brazil with 204 newborns > 34 gestational weeks. Gestational and obstetric history was evaluated, and newborns were randomized into two groups according to the product applied in the bath: the control group (CG), which used common liquid soap with pH 7.0 and experimental group (EG), which used children's liquid soap with pH 5.8. Evaluation was made immediately before and after bath with skin pH measurement, corneometry and clinical parameters (erythema, scaling and moisture), on the forehead, abdomen and thigh.ResultsThere was no difference between groups regarding gestational, obstetric and family history (p > 0.05). In CG, skin pH increased in the abdomen and thigh (p < 0.05). In EG there was an improvement in clinical parameters after bathing with: increased moisture, less erythema and less scaling (p < 0.05). On the forehead, there was a significant increase in pH after bathing (p < 0.001) similar in both groups, although no use of soap. There was no difference in corneometry between groups after bathing.ConclusionChildren's liquid soap with physiological pH maintained the acidic skin pH and moisture of the newborn's skin after the first bath, which reinforces the importance of using products with physiological pH in the hygiene of newborns.

Conjoined twins

Conjoined twins occur 1 in 200 000 live births with females predominating 3:1. The twins are classified according to their most prominent site of union together with the suffix ‘pagus’. The diagnosis can be suspected on prenatal scan as early as 12 weeks gestation. A recent advance is the use of 3-D MRI imaging to provide accurate anatomical details prenatally.Management can be divided into four phases:

• •prenatal counselling with termination recommended in cases with cardiac fusion;
• •non-operative treatment in the presence of complex cardiac or neural fusion;
• •emergency separation when one twin is dead or threatening the survival of the other or when there is a life-threatening surgically correctable congenital abnormality present;
• •planned separation usually around 3 months if the infants condition is stable.

     

Evolución del peso del prematuro con alta precoz y atención domiciliaria de enfermería

IntroductionIn-Home nursing care of the preterm newborn helps to bring the family situation to normal, promotes breastfeeding and development of the newborn, and enables the reorganization of health care resources. The purpose of this paper is to demonstrate that in-home nursing care of the preterm newborn leads to an increase in weight and a similar morbidity.Patients and methodologyA total of 65 cases and 65 controls (matched by weight, age and sex) were studied, all of them preterm newborns born in hospital and weighing less than 2100 g at discharge. In-home nursing care was carried out by a pediatrician neonatologist, as well as two nurses specialized in neonatology who made several visits to the home. Weight gain was calculated as g/day and g/Kg/day, comparing the first week of the study with the week prior to the beginning of the study.ResultsThe groups were comparable. Weight gain in the group with home nursing care was 38 g per day, significantly higher than the weight gain in the control group (31 g/day). The independent predictive variables of the increase in g/Kg/day during the study were in-home nursing care, male gender, breastfeeding less, and not having suffered from a peri-intraventricular hemorrhage. Neonatal morbidity was similar in both groups.ConclusionsIn-home care was associated with a greater weight gain of the newborn at home than during their stay in the hospital, and can be considered safe because neonatal morbidity was not increased     

Neonatal skin care

The relative importance of neonatal health and neonatal skin care has been highlighted in recent years as infant mortality rates have decreased while death rates during the neonatal period remain unacceptably high in many areas of the world. During the neonatal period, many newborns develop preventable, clinically apparent skin problems, and many more, especially preterm neonates, experience morbidity caused by compromised skin barrier integrity. Several strategies are available for protecting the integrity and promoting the hygiene of the skin and augmenting its function as a barrier to TEWL and heat loss and the entrance of infectious or toxic agents. Research defining optimal applications of many of these strategies, however, and the development of new approaches in skin care is one of the greatest challenges in pediatric dermatology and holds promise for improving neonatal outcome in the future. The ability to modulate epidermal barrier function and integrity relies largely on the topical use of protective materials and substances and manipulation of the external environment. As understanding of epidermal barrier development advances, perhaps pharmacologic manipulation of barrier development, as now practiced for augmentation of neonatal lung maturity, will become a reality. In the meantime, greater awareness among neonatal health care practitioners of state-of-the-art strategies for optimizing skin integrity in neonates is an important step toward improving neonatal health.

Serum phenylalanine in preterm newborns fed different diets of human milk

ObjectiveTo evaluate phenylalanine plasma profile in preterm newborns fed different human milk diets.MethodsTwenty-four very-low weight preterm newborns were distributed randomly in three groups with different feeding types: Group I: banked human milk plus 5% commercial fortifier with bovine protein, Group II: banked human milk plus evaporated fortifier derived from modified human milk, Group III: banked human milk plus lyophilized fortifier derived from modified human milk. The newborns received the group diet when full diet was attained at 15 ± 2 days. Plasma amino acid analysis was performedon the first and last day of feeding. Comparison among groups was performed by statistical tests: one way ANOVA with Tukey's post-test using SPSS software, version 20.0 (IBM Corp, NY, USA), considering a significance level of 5%.ResultsPhenylalanine levels in the first and second analysis were, respectively, in Group I: 11.9 ± 1.22 and 29.72 ± 0.73; in Group II: 11.72 ± 1.04 and 13.44 ± 0.61; and in Group III: 11.3 ± 1.18 and 15.42 ± 0.83 μmol/L.ConclusionThe observed results demonstrated that human milk with fortifiers derived from human milk acted as a good substratum for preterm infant feeding both in the evaporated or the lyophilized form, without significant increases in plasma phenylalanine levels in comparison to human milk with commercial fortifier.     

The Evolving Practice of Developmental Care in the Neonatal Unit: A Systematic Review

ABSTRACT

Many neonatal intensive care units (NICUs) are experiencing changes in their approaches to preterm infant care as they consider and incorporate the philosophy of individualized developmental care. The aim of this systematic review is to research current literature documenting the short-term effects of developmental care and the Newborn Individualized Developmental Care and Assessment Program (NIDCAP). The following databases were reviewed: PubMED, CINAHL, and PsychINFO by using the keywords developmental care, individualized care, preterm infant, early intervention, and NIDCAP. Fifty-four articles were found with a total of 15 matching the selection criteria. All 15 articles were assessed using a research design developed by the American Academy for Cerebral Palsy and Developmental Medicine (AACPDM). Twelve of the 15 articles contained strong Levels of Evidence (I or II). Our findings suggest evidence supporting developmental care and NIDCAP, however, further research documenting outcomes for preterm infants receiving developmental care and/or NIDCAP is needed.     

Development and Validation of Equations to Link Pediatric Evaluation of Disability Inventory (PEDI) Functional Skills Scores to PEDI-Computer Adaptive Test Scores for Youth with Cerebral Palsy

Abstract

Aim: The Pediatric Evaluation of Disability Inventory (PEDI) was revised to the PEDI-Computer Adaptive Test (PEDI-CAT). The PEDI has been used for over two decades to track function in youth, so it is important that follow-up data are not lost with this transition. The purpose of this study was to develop and validate equations for linking PEDI scores to PEDI-CAT scores.

Methods: Caregivers of 101 youth 6.1 to 19.8?years of age with cerebral palsy (CP) and classified at Gross Motor Classification System (GMFCS) Levels I-V completed the PEDI and PEDI-CAT. Scaled score data from this sample were used to develop and validate linking equations using least squares regression and bootstrap cross-validation techniques. Next, equations were tested in an independent sample of 35 children with developmental disabilities.

Results: The equations to predict PEDI-CAT scores exhibited excellent model fit. PEDI Self-care, Mobility, and Social Function explained 92%, 84%, and 85% of the variation in PEDI-CAT Daily Activities, Mobility, and Social/Cognitive domains, respectively. No differences were detected between actual and predicted PEDI-CAT scores across all domains and by GMFCS level for the equation development sample and for an equation validation independent sample.

Conclusions: The model fit was excellent; however, equations should be used cautiously when evaluating changes in function for individual children with ceiling level PEDI scores. Valid score prediction equations for youth with CP will assist with transitioning from the PEDI to the PEDI-CAT.     

Temperature monitoring in newborns using thermospot

Objective: Hypothermia is a common problem in newborns. This is more so in community environment especially in lowbirth weight and preterm babies.Methods: A simple liquid crystal temperature monitoring device was used in 20 infants on a continuous basis to monitor for hypothermia. This was compared with the measurement of rectal temperature using a rectal thermometer.The colour changes and measures to be taken when hypothermia occurs was explained to the mothers and was well understood by all.Results : The Thermo Spot was in agreement with the rectal temperature in 310 out of 313 measurements. This includes 299 times when temperature was normal; and 11 times when the temperature was hypothermic. It underestimated the temperature of three infants, falsely indicating hypothermia in a normothermic child with normal body temperature. It correctly identified hypothermia in every case.Conclusion: ThermoSpot device is a simple accurate device allowing continuous thermal monitoring of low birth weight infants, especially in resource poor setting.
