Effects of COVID-19-targeted non-pharmaceutical interventions on pediatric hospital admissions in North Italian hospitals, 2017 to 2022: a quasi-experimental study interrupted time-series analysis.

Background: The use of Non-Pharmaceutical Interventions (NPIs), such as lockdowns, social distancing and school closures, against the COVID-19 epidemic is debated, particularly for the possible negative effects on vulnerable populations, including children and adolescents. This study therefore aimed to quantify the impact of NPIs on the trend of pediatric hospitalizations during 2 years of pandemic compared to the previous 3 years, also considering two pandemic phases according to the type of adopted NPIs. Methods: This is a multicenter, quasi-experimental before-after study conducted in 12 hospitals of the Emilia-Romagna Region, Northern Italy, with NPI implementation as the intervention event. The 3 years preceding the beginning of NPI implementation (in March 2020) constituted the pre-pandemic phase. The subsequent 2 years were further subdivided into a school closure phase (up to September 2020) and a subsequent mitigation measures phase with less stringent restrictions. School closure was chosen as delimitation as it particularly concerns young people. Interrupted Time Series (ITS) regression analysis was applied to calculate Hospitalization Rate Ratios (HRR) on the diagnostic categories exhibiting the greatest variation. ITS allows the estimation of changes attributable to an intervention, both in terms of immediate (level change) and sustained (slope change) effects, while accounting for pre-intervention secular trends. Results: Overall, in the 60 months of the study there were 84,368 cases. Compared to the pre-pandemic years, statistically significant 35 and 19% decreases in hospitalizations were observed during school closure and in the following mitigation measures phase, respectively. The greatest reduction was recorded for "Respiratory Diseases," whereas the "Mental Disorders" category exhibited a significant increase during mitigation measures. ITS analysis confirms a high reduction of level change during school closure for Respiratory Diseases (HRR 0.19, 95%CI 0.08-0.47) and a similar but smaller significant reduction when mitigation measures were enacted. Level change for Mental Disorders significantly decreased during school closure (HRR 0.50, 95%CI 0.30-0.82) but increased during mitigation measures by 28% (HRR 1.28, 95%CI 0.98-1.69). Conclusion: Our findings provide information on the impact of COVID-19 NPIs which may inform public health policies in future health crises, plan effective control and preventative interventions and target resources where needed.

Depressive Symptoms in Fathers during the First Postpartum Year: The Influence of Severity of Preterm Birth, Parenting Stress and Partners' Depression.

Although preterm birth constitutes a risk factor for postpartum depressive symptomatology, perinatal depression (PND) has not been investigated extensively in fathers of very low (VLBW) and extremely low birth weight (ELBW) infants. This study explored paternal depression levels at 3, 9, and 12 months of infant corrected age, investigating also the predictive role played by the severity of prematurity, maternal and paternal PND levels, and parenting stress. We recruited 153 fathers of 33 ELBW, 42 VLBW, and 78 full-term (FT) infants, respectively. Depression was investigated by the Edinburgh Postnatal Depression Scale (EPDS) and distress by the Parenting Stress Index-Short Form-PSI-SF (Total and subscales: Parental Distress, Parent-Child Dysfunctional Interaction, and Difficult Child). ELBW fathers showed a significant decrease (improvement) in EPDS, total PSI-SF, and Parental Distress mean scores after 3 months. Paternal EPDS scores at 12 months were significantly predicted by VLBW and FT infants' birth weight categories, fathers' EPDS scores at 3 and 9 months, Parent-Child Dysfunctional Interaction subscale at 3 months, and Difficult Child subscale at 9 months. This study strengthens the relevance of including early routine screening and parenting support for fathers in perinatal health services, with particular attention to fathers who might be more vulnerable to mental health difficulties due to severely preterm birth.

Parental Distress and Affective Perception of Hospital Environment after a Pictorial Intervention in a Neonatal Intensive Care Unit.

Pictorial humanization is a useful intervention for the improvement of hospitalized patients' affective states. Despite benefits in many hospital wards having been well documented, so far, no attention was paid to the Neonatal Intensive Care Unit (NICU). The aim of the present study was to evaluate the levels of distress and the affective perception of the environment experienced by parents of infants hospitalized in a NICU after the implementation of an intervention of pictorial humanization. A sample of 48 parents was recruited, 25 before the intervention was performed (Control Group), and 23 after its implementation (Pictorial Humanization Group). All parents completed the "Rapid Stress Assessment Scale" and "Scales of the Affective Quality Attributed to Place" questionnaires. Despite results showing no significant differences on parental distress, after implementation of pictorial intervention parents reported a perception of the NICU as significantly more pleasant, exciting, and arousing, and less distressing, unpleasant, gloomy, and sleepy. A higher level of distress and a perception of the environment as less relaxing was predicted for the Control Group condition. The present study suggests that the pictorial intervention represents a useful technique to create more welcoming hospital environments and to reduce the negative effects associated with infant hospitalization.

Increase of Parkin and ATG5 plasmatic levels following perinatal hypoxic-ischemic encephalopathy.

Brain injury at birth is an important cause of neurological and behavioral disorders. Hypoxic-ischemic encephalopathy (HIE) is a critical cerebral event occurring acutely or chronically at birth with high mortality and morbidity in newborns. Therapeutic strategies for the prevention of brain damage are still unknown, and the only medical intervention for newborns with moderate-to-severe HIE is therapeutic hypothermia (TH). Although the neurological outcome depends on the severity of the initial insult, emerging evidence suggests that infants with mild HIE who are not treated with TH have an increased risk for neurodevelopmental impairment; in the current clinical setting, there are no specific or validated biomarkers that can be used to both correlate the severity of the hypoxic insult at birth and monitor the trend in the insult over time. The aim of this work was to examine the presence of autophagic and mitophagic proteins in bodily fluids, to increase knowledge of what, early at birth, can inform therapeutic strategies in the first hours of life. This is a prospective multicentric study carried out from April 2019 to April 2020 in eight third-level neonatal intensive care units. All participants have been subjected to the plasma levels quantification of both Parkin (a protein involved in mitophagy) and ATG5 (involved in autophagy). These findings show that Parkin and ATG5 levels are related to hypoxic-ischemic insult and are reliable also at birth. These observations suggest a great potential diagnostic value for Parkin evaluation in the first 6 h of life.

Severity of preterm birth and perinatal depressive symptoms in mothers and fathers: Trajectories over the first postpartum year.

BACKGROUND: Preterm birth has been recognized as a risk factor for perinatal depression (PND), with consequences for parenting and child development; however, the impact of severity of prematurity on parental PND course has not been studied extensively. Exploring the PND trajectory across postpartum period, investigating whether it changed according to birth weight and parental role, can help developing effective interventions. METHODS: At 3 (T1), 9 (T2) and 12 (T3) months postpartum, the Edinburgh Postnatal Depression Scale (EPDS) was administered to 177 parental couples, differentiated in 38 parents of extremely low birth weight (ELBW), 56 of very low birth weight (VLBW) and 83 of full-term (FT) infants. Trajectories were modeled by Growth Curve Models. RESULTS: As a function of time, results revealed a general decrease in PND across the year. Considering birth weight, ELBW parents showed higher PND levels at T1 and a higher reduction of symptoms over time than VLBW and FT ones. Given also parental role, ELBW mothers showed higher PND levels at T1 and a higher decrease of symptoms over time than VLBW and FT mothers and fathers. LIMITATIONS: Limitations included modest sample size, self-report measures, and unmeasured potential confounders. CONCLUSION: Findings suggest that premature birth in relation to its severity may lead to different affective reactions in mothers and fathers; particularly mothers, in case of more serious preterm condition, are at higher risk for PND in the first trimester, however showing improvement over time. Interventions should be promoted, and tailored, according to the risk connected to severity of prematurity.

Parental Book-Reading to Preterm Born Infants in NICU: The Effects on Language Development in the First Two Years.

BACKGROUND: After preterm birth, infants are at high risk for delays in language development. A promising intervention to reduce this risk is represented by the exposure to parental voices through book-reading in Neonatal Intensive Care Units (NICU). This study investigated the possible advantages of book-reading to preterm neonates during their NICU stay on their subsequent language development. METHODS: 100 families of preterm infants were recruited. The parents of 55 preterm infants (Reading Group) received a colored picture-book on NICU admission and were supported to read to their neonate as often as possible and to continue after hospital discharge. Forty-five infants (Control Group) were recruited before the beginning of the intervention. Infant language development was assessed with the Hearing and Language quotients of the Griffith Mental Development Scale at the corrected ages of 3, 6, 9, 12, 18 and 24 months. RESULTS: Regardless of group membership, Hearing and Language mean quotients decreased between 9 and 18 months; nevertheless, this decrease was considerably reduced in the Reading group, compared to the Control Group. CONCLUSIONS: Reading in NICUs represents a suitable intervention that could positively influence language development and parent-infant relationships in preterm children. The study findings support its implementation as a preventive measure.

Neuroprem 2: An Italian Study of Neurodevelopmental Outcomes of Very Low Birth Weight Infants.

Background: Despite the increased survival of preterm newborns worldwide, the risk of neurodevelopmental disabilities remains high. Analyzing the outcomes of the preterm population can identify risk factors and enable specific early interventions. Aims: Neuroprem is a prospective cohort study of very low birth weight (VLBW) infants that aims to evaluate the neurodevelopmental outcomes and risk factors for severe functional disability at 2 years of corrected age. Methods: Nine Italian neonatal intensive care units participated in the network. The Griffiths Mental Developmental Scales (GMDS-R) or the Bayley Scales of Infant and Toddler Development (BSDI III) and a neuro-functional evaluation (according to the International Classification of Disability and Health and Neuro-Functional Assessment, or NFA ICF-CY) were administered to VLBW infants at 24 months of corrected age. The primary outcome measure was severe functional disability, defined as cerebral palsy, bilateral blindness, deafness, an NFA ICF-CY of >2, a BSDI III cognitive composite score of <2 SD, or a GMDS-R global quotient score of <2 SD. Perinatal risk factors for severe functional disability were assessed through multivariate logistic regression analysis. Results: Among 502 VLBW survivors who completed the 24-month follow-up, 48 (9.6%) presented severe functional disability, of whom 27 had cerebral palsy (5.4%). Rates of severe functional disability and cerebral palsy were higher in neonates with a lower gestational age (p < 0.001). Overall, 147 infants (29.3%) were referred to neuromotor intervention. In the multivariate regression model, gestational age at birth OR 0.79; 95% CI 0.67-0.90; p = 0.001) and periventricular-intraventricular hemorrhage (OR 2.51; 95% CI 1.19-5.26; p = 0.015) were significantly associated with severe functional disability. Conclusion: Neuroprem 2 provides updated information on the neurodevelopmental outcomes of VLBW infants in a large Italian cohort. The overall rate of neurodevelopmental disabilities was quite lower than reported in the previous literature. These data indicate the need for structured follow-up programs from a national neonatal network perspective.

Reciprocal Influence of Depressive Symptoms Between Mothers and Fathers During the First Postpartum Year: A Comparison Among Full-Term, Very Low, and Extremely Low Birth Weight Infants.

Background: Perinatal depression (PND) in mothers and fathers of very low and extremely low birth weight (VLBW and ELBW) infants has not been studied extensively. In particular, no studies investigated the reciprocal influence of depressive symptoms during the first 12 months postpartum. This study aimed at exploring the impact of the severity of prematurity on maternal and paternal PND during the first postpartum year; specifically, we used an Actor-Partner Interdependence Model (APIM) to test the interdependence of both partners on depressive symptoms. Methods: A total of 177 mothers and 177 fathers were recruited, divided into 38 couples with ELBW infants, 56 with VLBW, and 83 of full-term (FT) infants. PND was evaluated by the Edinburgh Postnatal Depression Scale (EPDS) at 3, 9, and 12 months postpartum (corrected age for preterm infants). Results: Maternal depressive symptoms at 3 months were positively related to those at 9 and 12 months in the 3 groups. Conversely, paternal depressive symptoms assessed at 3 months were positively related to those measured at 9 months for the ELBW group, 12 months for the VLBW group, 9 and 12 months for FT condition. Furthermore, a significantly positive partner effect was observed regarding the influence of 3 month maternal depressive symptoms on paternal depressive symptoms at 9 months, but only in the case of the VLBW group. Conclusion: Prematurity represents a very specific scenario in the transition to parenthood, leading to specific reactions in mothers and fathers, especially in high-risk conditions. Results should be deepened given the relevance of their clinical implications.

Home Management of Children With COVID-19 in the Emilia-Romagna Region, Italy.

In most children, coronavirus disease 2019 (COVID-19) is a mild or moderate disease. Moreover, in a relevant number of cases, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection remains totally asymptomatic. All these findings seem to suggest that otherwise healthy children with suspected COVID-19 might be managed in the community in most cases, thus avoiding hospital admission and closely related medical, social and economic problems, including overwhelming hospitals. Unfortunately, home management of children with suspected COVID-19 rarely occurs, and many children with suspected or laboratory-confirmed SARS-CoV-2 infection are frequently hospitalized irrespective of the severity of disease. To evaluate the role of community health houses (CHHs) in the management of children with COVID-19, 1,009 children with suspected SARS-CoV-2 infection were studied in Emilia-Romagna Region, Italy. Among them, 194 (19.2%) resulted positive for SARS-CoV-2. The majority (583, 58%) were tested at home by CHHs, while 426 (42%) were brought to the hospital for testing. The patients who were managed in the hospital had a significantly lower median age than those who were managed at home (2 vs. 12 years, p < 0.001). Exposure to SARS-CoV-2 cases within the family was significantly more frequent among those who were managed at home (82 vs. 46%, p < 0.05). The clinical findings were similar between the children who were managed at home and those who were managed in the hospital. Only one of the children managed at home (0.7%) required hospitalization; in comparison, 26 (48%) of those whose swab samples were taken at the hospital were hospitalized. Our research shows for the first time the importance of CHHs in the management of COVID-19 in children; because of the high frequency of mild to moderate cases, management by CHHs can reduce the care load in hospitals, providing enormous advantages on the familial, medical, social, and economic levels. These findings could be useful for suggesting a territorial rather than hospital-based strategy in pediatrics in the case of a new wave of the epidemic.

Developmental Dimensions in Preterm Infants During the 1st Year of Life: The Influence of Severity of Prematurity and Maternal Generalized Anxiety.

BACKGROUND: The literature has recognized premature birth as a risk factor for infant development and maternal anxiety. This study investigated the impact of the severity of birth weight, as well as of maternal anxiety at 3 months of infants' corrected age, on infants' outcomes during the 1st year postpartum. Moreover, it described the longitudinal trajectories of developmental outcomes, additionally exploring the impact of anxiety. METHODS: The study compared 147 mothers and their 147 newborns, differentiated in 25 Extremely Low Birth Weight (ELBW), 41 Very Low Birth Weight (VLBW), and 81 Full-Term (FT) infants. At 3, 9, and 12 months (corrected age in the case of preterm infants) the level of infants' development was investigated according to the 5 quotients (Locomotor, Personal and Social, Hearing and Language, Eye-hand Co-ordination and Performance) of the Griffiths Mental Development Scales (GMDS-R). During the assessment of 3 months, mothers fulfilled Penn State Worry Questionnaire (PSWQ) to evaluate the presence of generalized anxiety. RESULTS: Among the 5 GMDS-R quotients, significant effect of severity of birth weight emerged only for Performance quotient: preterm infants (ELBW at 3 months; VLBW at 12 months) showed lower scores than FT ones. Moreover, this quotient decreased from 3 to 9 and to 12 months for VLBW and FT infants, while it was stable for ELBW ones. A significant interaction between severity of birth weight and maternal anxiety emerged for Hearing and Language and Locomotor quotients. In the first case, scores for ELBW infants, independently from maternal anxiety, decreased from 9 to 12 months. The same results emerged for VLBW infants, in the case of non-anxious mothers. Regarding Locomotor quotient, mean scores decreased from 3 to 9 and to 12 months for all groups in the case of non-anxious mothers. Conversely, when mothers were anxious, this decrease emerged only for VLBW infants. Lastly, ELBW, VLBW and FT showed difference in the growth and slope of the trajectories of different quotients. CONCLUSION: The severity of birth weight for preterm infants, also in interaction with maternal anxiety, had significant and specific impact on different dimensions of infants' development. Clinical implications of these results underline the need for individualized interventions.

Neuroprem: the Neuro-developmental outcome of very low birth weight infants in an Italian region.

INTRODUCTION: The survival of preterm babies has increased worldwide, but the risk of neuro-developmental disabilities remains high, which is of concern to both the public and professionals. The early identification of children at risk of neuro-developmental disabilities may increase access to intervention, potentially influencing the outcome. AIMS: Neuroprem is an area-based prospective cohort study on the neuro-developmental outcome of very low birth weight (VLBW) infants that aims to define severe functional disability at 2 years of age. METHODS: Surviving VLBW infants from an Italian network of 7 neonatal intensive care units (NICUs) were assessed for 24 months through the Griffiths Mental Developmental Scales (GMDS-R) or the Bayley Scales of Infant and Toddler Development (BSDI III) and neuro-functional evaluation according to the International Classification of Disability and Health (ICF-CY). The primary outcome measure was severe functional disability at 2 years of age, defined as cerebral palsy, a BSDI III cognitive composite score < 2 standard deviation (SD) or a GMDS-R global quotients score < 2 SD, bilateral blindness or deafness. RESULTS: Among 211 surviving VLBW infants, 153 completed follow-up at 24 months (72.5%). Thirteen patients (8.5%) developed a severe functional disability, of whom 7 presented with cerebral palsy (overall rate of 4.5%). Patients with cerebral palsy were all classified with ICF-CY scores of 3 or 4. BSDI III composite scores and GMDS-R subscales were significantly correlated with ICF-CY scores (p < 0.01). CONCLUSION: Neuroprem represents an Italian network of NICUs aiming to work together to ensure preterm neuro-developmental assessment. This study updates information on VLBW outcomes in an Italian region, showing a rate of cerebral palsy and major developmental disabilities in line with or even lower than those of similar international studies. Therefore, Neuroprem provides encouraging data on VLBW neurological outcomes and supports the implementation of a preterm follow-up programme from a national network perspective.

Early appendectomy vs. conservative management in complicated acute appendicitis in children: A meta-analysis.

BACKGROUND: No consensus exists among surgeons regarding the optimal treatment of complicated acute appendicitis in children (CAA). Existing studies present heterogeneity of data and only few studies analyzed free perforated appendicitis (FPA) separately from appendicular abscess (AAb) and appendicular phlegmon (AP). METHOD: Studies which have been judged eligible for this systematic review and consequent meta-analysis are those comparing non-operative management (NOM) with operative management (OM) in children with CAA. Studies were subgrouped between those analyzing mixed patients with CAA, those focusing on patients with AAb/AP and those focusing on patients with FPA. RESULTS: Fourteen studies fulfilled the inclusion criteria and were included in the meta-analysis with a total of 1288 patients. In the fixed-effects model the complication rate was significantly favorable to the initial NOM arm for the AAb/AP subgroup (RR = 0.07, 95%CI = 0.02-0.27) and to the OM arm for the FPA subgroup (RR = 1.86, 95%CI = 1.20-2.87); the re-admission rate was significantly favorable to the initial NOM arm for the AAb/AP subgroup (RR = 0.35, 95%CI = 0.13-0.93) and to the OM arm for the FPA subgroup (RR = 1.49, 95%CI = 1.49-7.44). There was no statistical heterogeneity for the two subgroups of patients. The costs weren't significantly different between NOM and OM. The length of stay was favorable to OM. The pooled proportion rate of NOM success was 90%, the pooled relapse rate of appendicitis was 15.4%. CONCLUSIONS: Children with AAb/AP reported better results in terms of complication rate and re-admission rate if treated with NOM. Conversely children with FPA showed lower complication rate and re-admission rate if treated with OM. LEVEL OF EVIDENCE: II.

Strategies of Increased Protein Intake in ELBW Infants Fed by Human Milk Lead to Long Term Benefits.

Objective: The aim of this observational study was to evaluate the effects of two different protein intake regimes on feeding tolerance, in-hospital growth, anthropometric data and psychomotor outcome up to 24 months corrected age (CA) in extremely low birth-weight (ELBW; birth weight <1000 g) infants. Methods: During the period 2008-2013, 52 ELBW infants admitted at birth to two Neonatal Intensive Care Units of Emilia Romagna (Italy) were fed according to different protocols of protein fortification of human milk: an estimated protein intakes at maximum fortification levels of 3.5 gr/kg/day in the Standard Nutrition Population-SNP group (n = 26) and 4.8 g/kg/day in the Aggressive Nutrition Population-ANP group (n = 26). During hospitalization, infants' growth, biochemical indices of nutritional status, enteral intake, feeding tolerance, clinical history and morbidity were evaluated. After discharge, anthropometric data and psychomotor outcome, evaluated by Revised Griffiths Mental Development Scales (GMDS-R) 0-2 years, were assessed up to 24 months CA. Results: During hospitalization, the ANP group showed significantly higher weight (18.87 vs. 15.20 g/kg/day) and head circumference (0.70 vs. 0.52 cm/week) growth rates compared to SNP, less days of parenteral nutrition (7.36 ± 2.7 vs. 37.75 ± 29.6) and of hospitalization (60.0 ± 13.3 vs. 78.08 ± 21.32). After discharge, ANP infants had a greater head circumference compared to SNP (45.64 ± 0.29; 46.80 ± 0.31). Furthermore, the General Quotient of GMDS-R mean scores in the SNP group significantly decreased from 12 to 24 months CA, while no difference was seen in the ANP group. Conclusions: Increased protein intake may provide short and long term benefits in terms of growth and neurodevelopment in human milk-fed ELBW infants.

High protein intake in human/maternal milk fortification for ≤1250 gr infants: intrahospital growth and neurodevelopmental outcome at two years.

BACKGROUND AND AIM OF THE STUDY: Extrauterine growth restriction and failure to thrive remain a major problem in Extremely Low Birth Weight infants. Nutritional support in preterm babies has the objective to improve the achieve rate of growth similar to those of the fetus in utero at the equivalent gestational age. The aim of the study was to evaluate feeding tolerance, intrahospital growth, neurological outcome and anthropometric data until 24 months of corrected age (mca) from different protein intake assumed by preterm babies <1250 g during their stay in NICU. METHODS: The study evaluates auxological/neurodevelopmental outcomes until 24 months of corrected age (mca) in preterm infants with different protein intake (control group-CG: 3,5g Kg‾¹ perday; intervention group-PSG: 4,8g Kg‾¹ per day). RESULTS: PSG group showed a significant higher length growth at 9 mca (p 0,04) and hearing/language score of Griffiths Mental Development Score (GMDS) at 12 (p 0,03) and 18 mca  (p<0,05) comparing with CG. PSG-ELBW preterms showed an higher intrahospital head circumference (p 0,02) and length growth rate (p 0,04), greater Performance (p 0,04) and Hearing/Language (p 0,03) scores of GMDS at 3 and 12 mca. PSG-SGA preterms showed significantly higher scores in GMDS scores at 18 and 24 mca except for the locomotor domain. CONCLUSIONS: Supplemental enteral proteins lead to benefits of reduced postnatal growth restriction and better neurological outcome in preterm infants <1000 g and in those SGA <1250 g.

Intensive care of children with burn injuries and the role of the multidisciplinary team.

Trauma from burns and scalds in children is more common and more damaging than in adults, and may indicate abuse. The main goal of intensive care of an acute burn is to limit the extent of the systemic insult. Effective treatment of such acute physiological changes requires experienced monitoring by multidisciplinary teams, following appropriate emergency protocols at specialised burn centres in cases of major trauma. First aid involves maintaining a patent airway, supporting circulation and respiration, arresting the burning, managing pain and distress, reducing infection and considering transfer to specialist care. Advances in techniques and treatment have increased survival rates and ultimate quality of life, but education and prevention programmes are still required at all levels to reduce the incidence of burns among children.

Establishment, operation and development of a donor human milk bank.

Human milk is very valuable in premature infant nutrition. The collection, screening, processing and distribution of donor human milk are described in this report. These activities take place in the Donor Human Milk Bank (DHMB) of the Large Romagna Area (LRA) in Italy, the development of which is also described here. Over the years, the activities of this bank, which is located in Cesena Hospital, in the center of the LRA, have developed from an informal and domestic-level activity to become a multistep controlled process designed to prevent the possibility of disease transmission. This little food-supply industry, run by a multi-disciplinary team with strict rules and diverse responsibilities, complies with the Hazards Analysis and Critical Control Points (HACCP) system.

Growth and neurological outcome in ELBW preterms fed with human milk and extra-protein supplementation as routine practice: do we need further evidence?

Extremely-low-birth-weight infants (ELBW) should be given nutrients to enable them to grow at the same rate as foetuses of the same gestational age, and lean body components, particularly the brain, are dependent on protein intake. Fortified human milk remains the best food for these preterms. Two groups of preterm infants weighing 580-1250 g and with a gestational age of 23-32 weeks were fed with different protein intakes in fortified human/maternal milk (3.5 g kg(-1) per day and 4.8 g kg(-1) per day in the control and extra-protein groups, respectively). The tolerance, intrahospital growth, neurological outcome and anthropometric data until 9 months corrected age were evaluated. The extra-protein regime showed an intrahospital growth advantage (mostly in growth of head circumference, p 0.02, and length, p 0.04) only in the preterms weighing 580-980 g and aged 23-30 weeks. In the same preterms, the Griffith Development Mental Score at 3 months corrected age showed higher scores than in the control group (p 0.04). Growth during the post-discharge period for the experimental group at 9 months corrected age showed mean z-score values for length higher than those in the control group (p 0.04).

Neonatal arterial iliac thrombosis in type-I protein C deficiency: a case report.

A male infant born by caesarean section at 38 weeks of gestational age (B.W. 4055 g; Apgar 9-10), in the first two hours of life his right leg became hypo-vascularized. Normal values of leukocytes, red cells, haematocrit, hemoglobin, platelets. C-Reactive Protein negative. Electrolytes and coagulation tests were normal. Normal vitamin K coagulation proteins levels. Serological tests for TORCH (IgM) and Parvovirus (IgG and IgM) were negative. Sonography showed a reduced blood flow in the iliac artery and reported a 1 cm long vessel thrombosis. From 8 hours of life we administered an intravenous infusion of unfractionated heparin (UFH) 75 UI/Kg for the first 10 minutes then 28 UI/Kg/h.On the 2nd day tests were performed to assess absence of inhibiting-clot factors. The dosage of homocysteine, protein S and antithrombin was normal. FV Leiden and antiphospholipid antibodies were negative. The mapping of G20210A prothrombin's gene resulted normal, whereas the concentration of Protein C was lower than normal: activity 46% (68-150%), antigen 35% (70-150%).The same deficiency was also found in the father. The mother showed normal concentrations. No episodes of thrombosis events were documented in the family. The intravenous unfractionated heparin (UFH) therapy was replaced after 64 hours by subcutaneous nadroparin 600 UI twice/day, which was stopped 5 days later when the vessel sonographic images were completely normal. During the hospitalization the infant didn't show bleeding. The child was followed-up yearly until 4 years of age: he was well and had a normal body and mental development.The final diagnosis is likely to be of a permanent protein C deficiency in heterozygous form. Our case is interesting because the first manifestation was an important thrombosis of large vessel that occurred within a few hours of life in absence of perinatal risk factors, as if it was a homozygous disease, but the patient had a heterozygotic form. In literature few cases are reported of heterozygous forms that became symptomatic, but only in old age.After a severe first manifestation, a normal and asymptomatic development is uncommon without new thrombotic episodes. In our patient the neonatal thrombosis was the sole event in his life.

Mode of delivery in the preterm gestation and maternal and neonatal outcome.

OBJECTIVE: To determine if the mode of delivery in preterm gestations is associated with changes in maternal and neonatal outcome. METHODS: A retrospective cohort study that included all singleton deliveries occurring after spontaneous onset of labour between 25+0 and 32+6 weeks of gestation. Cases of early preterm delivery were identified from clinical records and classified according to the mode of delivery. The following outcomes were derived for each case and compared between caesarean and vaginal deliveries: perinatal death, cranial findings compatible with haemorrhage or white matter disease in the neonate, new-onset of maternal severe anaemia or pyrexia. RESULT: From 1990 to 2007, 109 cases of spontaneous preterm labour were retrospectively selected, including 50 (45.8%) caesarean sections and 59 (54.2%) vaginal deliveries. Perinatal death occurred in 10 infants (9.1%), whereas among survivors abnormal cerebral findings were detected in 20, including 6 cases with haemorrhage, 12 with white matter findings and 2 with both. At multiple logistic regression, a birthweight lower than 1100 g was the only predictor of all adverse outcomes, whereas male sex increased the risk of white matter findings. Caesarean section compared to vaginal delivery conferred a higher risk of maternal complications (23/50 or 46% vs. 6/59 or 10.2%; OR: 11.9, CI 95%: 4.2-333; p<0.0005). CONCLUSIONS: In severely premature infants born after spontaneous onset of labour, the risk of adverse perinatal outcome does not seem to depend upon the mode of delivery, whereas the risk of maternal complications is significantly increased after Caesarean section.
