Supplemental Iron and Recombinant Erythropoietin for Anemia in Infants Born Very Preterm: A Survey of Clinical Practice in Europe.

OBJECTIVES: To survey practices of iron and recombinant human erythropoietin (rhEpo) administration to infants born preterm across Europe. STUDY DESIGN: Over a 3-month period, we conducted an online survey in 597 neonatal intensive care units (NICUs) of 18 European countries treating infants born with a gestational age of <32 weeks. RESULTS: We included 343 NICUs (response rate 56.3%) in the survey. Almost all NICUs (97.7%) routinely supplement enteral iron, and 74.3% of respondents to all infants born <32 weeks of gestation. We found that 65.3% of NICUs routinely evaluate erythropoiesis and iron parameters beyond day 28 after birth. Most NICUs initiate iron supplementation at postnatal age of 2 weeks and stop after 6 months (34.3%) or 12 months (34.3%). Routine use of rhEpo was reported in 22.2% of NICUs, and in individual cases in 6.9%. RhEpo was mostly administered subcutaneously (70.1%) and most frequently at a dose of 250 U/kg 3 times a week (44.3%), but the dose varied greatly between centers. CONCLUSIONS: This survey highlights wide heterogeneity in evaluating erythropoietic activity and iron deficiency in infants born preterm. Variation in iron supplementation during infancy likely reflects an inadequate evidence base. Current evidence on the efficacy and safety profile of rhEpo is only poorly translated into clinical practice. This survey demonstrates a need for standards to optimize patient blood management in anemia of prematurity.

Off-label and unlicensed medicine prescribing in university hospital paediatric wards in Finland: A prospective study.

AIMS: The aim of this research is to study the prevalence of prescribing medicines for off-label (OL) use and unlicensed (UL) medicines for children during hospitalization in 2021 and to assess changes compared with 2011. METHODS: The study included all patients aged <18 years who were treated in the neonatal intensive care unit (NICU) or general paediatric ward of Kuopio University Hospital (KUH), Finland, during 4 weeks in April and May 2021. Their background data and daily information on medicine prescriptions were collected from patient records. The prescriptions were classified as OL, UL or on-label/approved. The type of OL category was defined. RESULTS: Altogether, 165 children aged 0-17 years (median 3.2 years) were treated in the paediatric wards (46 in the NICU and 119 in the general ward). In total, 1402 prescriptions were made for 153 children (93%). The proportion of OL and UL prescriptions decreased significantly from 55% in 2011 to 45% (age-adjusted proportion) in 2021 (P < .001). The proportion of patients receiving at least 1 UL medicine prescription decreased from 53% in 2011 to 30% (age-adjusted proportion) in 2021 (P < .001). About 76% of hospitalized children were still prescribed either OL prescription or UL medicine in 2021. CONCLUSION: The prescriptions for OL use and UL medicines were less prevalent in 2021 than 2011, but still a majority of hospitalized children were prescribed either medicine for OL use or UL medicine in 2021. This indicates a persisting need for approved medicines in children suggesting that revision of EU Paediatric Regulation 2007 is necessary.

Longitudinal growth of children born with gastroschisis or omphalocele.

Normal childhood growth is an indicator of good health, but data addressing the growth of children born with abdominal wall defects (AWDs) are limited. The detailed growth phenotypes of children born with gastroschisis or omphalocele are described and compared to peers without AWDs from birth to adolescence. Data from 183 gastroschisis and 144 omphalocele patients born between 1993 and 2017 were gathered from Finnish nationwide registers and electronic health records. Weight (n = 3033), length/height (n = 2034), weight-for-length (0-24 months, n = 909), and body mass index measures (2-15 years, n = 423) were converted into sex- and age-specific Z-scores. Linear mixed models were used for comparisons. Intrauterine growth failure was common in infants with gastroschisis. Birth weight Z-scores in girls and boys were - 1.2 (0.2) and - 1.3 (0.2) and length Z-scores - 0.7 (0.2) and - 1.0 (0.2), respectively (p < 0.001 for all comparisons to infants without AWDs). During early infancy, growth failure increased in infants with gastroschisis, and thereafter, catch-up growth was prominent and faster in girls than in boys. Gastroschisis children gained weight and reached their peers' weights permanently at 5 to 10 years. By 15 years or older, 30% of gastroschisis patients were overweight. Infants with omphalocele were born with a normal birth size but grew shorter and weighing less than the reference population until the teen-age years. CONCLUSION: Children with gastroschisis and omphalocele have distinct growth patterns from fetal life onwards. These growth trajectories may also provide some opportunities to modulate adult health. WHAT IS KNOWN: • Intrauterine and postnatal growth failure can be seen frequently in gastroschisis and they often show significant catch-up growth later in infancy. It is assumed that part of the children with gastroschisis will become overweight during later childhood. WHAT IS NEW:  â€¢ The longitudinal growth of girls and boys with gastroschisis or omphalocele is described separately until the teenage years. The risk of gaining excessive weight in puberty was confirmed in girls with gastroschisis.

Shared responsibility for decision-making in NICU: A scoping review.

BACKGROUND: Shared responsibility is an essential part of family-centred care and it characterizes the relationship between parents and healthcare professionals. Despite this, little is known about their shared responsibility for decision-making in neonatal intensive care units. AIM: The aim of this scoping review was to identify previous studies on the subject and to summarize the knowledge that has been published so far. METHOD: The review was conducted using electronic searches in the CINAHL, PubMed, Scopus and PsycINFO databases and manual searches of the reference lists of the selected papers. The searches were limited to peer-reviewed papers that had been published in English from 2010 to September 2021. The data were selected based on inclusion and exclusion criteria and the findings were inductively summarized. We identified eight papers that met the inclusion criteria. ETHICAL CONSIDERATIONS: The scoping review was conducted according to good scientific practice by respecting authorship and reporting the study processes accurately, honestly and transparently. RESULTS: The results showed that shared responsibility for decision-making was based on the parents' intentions, but the degree to which they were willing to take responsibility varied. The facilitating and inhibiting factors for shared responsibility for decision-making were related to the communication between parents and professionals. The impact was related to the parents' emotions. CONCLUSION: It is essential that parents and professionals negotiate how both parties will contribute to their shared responsibility for decision-making. This will enable them to reach a mutual understanding of what is in the infants' best interests and to mitigate the emotional burden of decisions in neonatal intensive care units. More research is needed to clarify the concept of shared responsibility for decision-making in this intensive care context.

Pacifier use and breastfeeding in term and preterm newborns-a systematic review and meta-analysis.

The purpose of this study is to assess whether pacifier use is associated with breastfeeding success in term and preterm newborns and whether it influences hospitalization time in preterm newborns. Four databases were searched for randomized controlled trials (RCTs), and a systematic review and meta-analysis were conducted. The risk of bias and evidence quality, according to the GRADE methodology, were analyzed. Risk ratios with 95% confidence intervals (CI) for dichotomous outcomes and mean difference (MD) for continuous outcomes were used. The random effect model was used if heterogeneity was high (I2 over 40%). We screened 772 abstracts, assessed 44 full texts, and included 10 studies, of which 5 focused on term and 5 on preterm newborns. There were a few concerns about the risk of bias in 9 of the 10 studies. Breastfeeding rates were analyzed at 2, 3, 4, and 6 months, and the success rates were similar between the restricted and free pacifier use groups (evidence quality was moderate to high). In preterm neonates, the use of a pacifier shortened the duration of hospitalization by 7 days (MD 7.23, CI 3.98-10.48) and the time from gavage to total oral feeding by more than 3 days (MD 3.21 days, CI 1.19-5.24) (evidence quality was ranked as moderate).   Conclusions: Based on our meta-analysis, pacifier use should not be restricted in term newborns, as it is not associated with lower breastfeeding success rates. Furthermore, introducing pacifiers to preterm newborns should be considered, as it seems to shorten the time to discharge as well as the transition time from gavage to total oral feeding. What is Known: • Observational studies show that infants who use a pacifier are weaned from breastfeeding earlier. • Previous randomized studies have not presented such results, and there have been no differences in the successful breastfeeding rates regardless of the use of pacifier. What is New: • Term and preterm newborns do not have worse breastfeeding outcomes if a pacifier is introduced to them, and additionally preterm newborns have shorter hospitalization times. • The decision to offer a pacifier should depend on the caregivers instead of hospital policy or staff recommendation, as there is no evidence to support the prohibition or restriction.

Comparison of three risk stratification scores in gastroschisis neonates: gastroschisis prognostic score, gastroschisis risk stratification index and complex gastroschisis.

PURPOSE: The aim of the study was to compare and evaluate the utility of three different risk stratification scores for gastroschisis neonates; simple/complex gastroschisis, gastroschisis prognostic score and risk stratification index. METHODS: Data of neonates born with gastroschisis between the years 1993 and 2015 were collected. The national registers and patient records of four Finnish University Hospitals were retrospectively reviewed. Logistic and linear regression analysis were performed to identify independent predictors for adverse outcomes. The efficacy of these prognostic methods was further assessed using ROC-curves and DeLong (1988) test. RESULTS: Gastroschisis risk stratification index was an acceptable predictor of in-hospital mortality, AUC 0.70, 95% CI 0.48-0.91, p = 0.049. Complex gastroschisis and gastroschisis prognostic score were able to predict short bowel syndrome, AUC 0.80, 95% CI 0.58-1.00, p = 0.012 and AUC 0.80, 95% CI 0.59-1.00, p = 0.012, respectively. CONCLUSION: There are three easily obtainable risk stratification scores for outcome prediction in gastroschisis patients, however, their predictive ability did not have a statistical difference in the present study. The Gastroschisis risk stratification index seemed to perform moderately well in mortality prediction.

Psychiatric Symptoms, Posttraumatic Growth, and Life Satisfaction Among Parents of Seriously Ill Infants: A Prospective Case-Controlled Study.

We evaluated psychiatric symptoms, posttraumatic growth, and life satisfaction among the parents (n = 34) of newborns (n = 17) requiring therapeutic hypothermia or urgent surgery (interest group). Our control group included 60 parents of healthy newborns (n = 30). The first surveys were completed soon after diagnosis or delivery and the follow-up surveys 1 year later (participation rate 88% in the interest group and 70% in the control group). General stress was common in both groups but was more prevalent in the interest group as were depressive symptoms, too. Anxiety was more common in the interest group, although it showed a decrease from the baseline in both groups. Life satisfaction had an inverse correlation with all measures of psychiatric symptoms, and it was lower in the interest group in the early stage, but similar at 12 months due to the slight decline in the control group. Mothers in the interest group had more anxiety and depressive symptoms than fathers in the early stage. Mothers had more traumatic distress than fathers at both time points. Half of the parents experienced substantial posttraumatic growth at 12 months. In conclusion, the serious illness of an infant substantially affects the well-being of the parents in the early stages of illness and one year after the illness.

Sex-typical behavior in children born preterm at very low birth weight.

BACKGROUND: Perinatal events may alter psychosexual development. We aimed to assess whether a preterm birth at very low birth weight (VLBW; <1500 g) or antenatal synthetic glucocorticoids (sGC) given to the mother are associated with altered sex-typical behavior in childhood. METHODS: Sex-typical behavior was assessed using the Pre-school Activities Inventory (PSAI) at the mean age of 4.9 years (SD 1.6) in 879 children, of whom 143 were preterm with VLBW (PT <1500 g, all exposed to sGC), 282 were preterm with birth weight ≥1500 g (PT ≥1500 g, 171 exposed to sGC), and 454 were full term (FT, 166 exposed to sGC). RESULTS: Antenatal sGC was not associated with PSAI scores in either sex. PT <1500 g boys had less male-typical PSAI scores than other boys, even in multivariate model adjusting for age, maternal age, antenatal sGC, number of brothers and sisters, and motor or cognitive impairment. PT <1500 g girls had less female-typical PSAI scores than other girls in the multivariate model. The effect size was small (d = 0.03) for both sexes. CONCLUSIONS: Preterm birth with VLBW is associated with reduced sex-typical behavior in childhood, which is in line with the previous data indicating altered psychosexual development in adults born preterm. Mechanisms underlying these observations are not fully understood. IMPACT: Preterm birth is associated with reduced rates of marriage and reproduction in adulthood, but sex-typical behavior in children born preterm has not been studied before. The results of this study indicate that preterm birth with very low birth weight <1500 g is associated with reduced sex-typical behavior in childhood in both sexes. These observations are in line with the previous data indicating altered psychosexual development in adults born preterm. Mechanisms underlying these observations are not fully understood and require further studies.

Long-term hospital admissions and surgical treatment of children with congenital abdominal wall defects: a population-based study.

Congenital abdominal wall defects, namely, gastroschisis and omphalocele, are rare congenital malformations with significant morbidity. The long-term burden of these anomalies to families and health care providers has not previously been assessed. We aimed to determine the need for hospital admissions and the requirement for surgery after initial admission at birth. For our analyses, we identified all infants with either gastroschisis (n=178) or omphalocele (n=150) born between Jan 1, 1998, and Dec 31, 2014, in the Register of Congenital Malformations. The data on all hospital admissions and operations performed were acquired from the Finnish Hospital Discharge Register between Jan 1, 1998, and Dec 31, 2015, and compared to data on the whole Finnish pediatric population (0.9 million) live born 1993-2008. Patients with gastroschisis and particularly those with omphalocele required hospital admissions 1.8 to 5.7 times more than the general pediatric population (p<0.0001). Surgical interventions were more common among omphalocele than gastroschisis patients (p=0.013). At the mean follow-up of 8.9 (range 1.0-18.0) years, 29% (51/178) of gastroschisis and 30% (45/150) of omphalocele patients required further abdominal surgery after discharge from the neonatal admission.Conclusion: Patients with gastroschisis and especially those with omphalocele, are significantly more likely than the general pediatric population to require hospital care. Nevertheless, almost half of the patients can be treated without further surgery, and redo abdominal surgery is only required in a third of these children. What is Known: • Gastroschisis and omphalocele are congenital malformations with significant morbidity • There are no reports on the long-term need for hospital admissions and surgery in these children What is New: • Patients with abdominal wall defects are significantly more likely than the general pediatric population to require hospital care • Almost half of the patients can be treated without further surgery, and abdominal redo operations are only required in a third of these children.

The association of perinatal and clinical factors with outcomes in infants with gastroschisis-a retrospective multicenter study in Finland.

The aim of the present study was to assess the prognostic factors for the outcome of gastroschisis in Finland. A retrospective multicenter study of gastroschisis patients born between 1993 and 2015 in four Finnish university hospitals was undertaken, collecting perinatal, surgical, and clinical data of neonates for uni- and multifactorial modeling analysis. The aim of the present study was to identify risk factors for mortality and the composite adverse outcome (death and/or short bowel syndrome or hospital stay > 60 days). Of the 154 infants with gastroschisis, the overall survival rate was 90.9%. In Cox regression analysis, independent risk factors for mortality included liver herniation, pulmonary hypoplasia, relaparotomy for perforation or necrosis, abdominal compartment syndrome, and central line sepsis. Furthermore, a logistic regression analysis identified central line sepsis, abdominal compartment syndrome, complex gastroschisis, and a younger gestational age as independent predictors of the composite adverse outcome.Conclusion: The risk of death is increased in newborns with gastroschisis who have liver herniation, pulmonary hypoplasia, abdominal compartment syndrome, relaparotomy for perforation or necrosis, or central line-associated sepsis. Special care should be taken to minimize the risk of central line sepsis in the clinical setting. What is known: • Gastroschisis is a relatively rare congenital anomaly of the abdominal wall and its incidence is increasing. • Complex gastroschisis has been reported to increase risk of mortality and complications. What is new: • Central line sepsis was found to be independently associated with mortality in gastroschisis patients. • Liver herniation was also significantly associated with mortality.

High incidence of inguinal hernias among patients with congenital abdominal wall defects: a population-based case-control study.

The aim of this nationwide population-based case-control study was to assess the incidence of inguinal hernia (IH) among patients with congenital abdominal wall defects. All infants born with congenital abdominal wall defects between Jan 1, 1998, and Dec 31, 2014, were identified in the Finnish Register of Congenital Malformations. Six controls matched for gestational age, sex, and year of birth were selected for each case in the Medical Birth Register. The Finnish Hospital Discharge Register was searched for relevant diagnosis codes for IH, and hernia incidence was compared between cases and controls. We identified 178 infants with gastroschisis and 150 with omphalocele and selected randomly 1968 matched, healthy controls for comparison. Incidence of IH was significantly higher in gastroschisis girls than in matched controls, relative risk (RR) 7.20 (95% confidence interval [CI] 2.25-23.07). In boys with gastroschisis, no statistically significant difference was observed, RR 1.60 (95% CI 0.75-3.38). Omphalocele was associated with higher risk of IH compared to matched controls, RR 6.46 (95% CI 3.90-10.71), and the risk was equally elevated in male and female patients.Conclusion: Risk of IH is significantly higher among patients with congenital abdominal wall defects than in healthy controls supporting hypothesis that elevated intra-abdominal pressure could prevent natural closure of processus vaginalis. Parents should be informed of this elevated hernia risk to avoid delays in seeking care. We also recommend careful follow-up during the first months of life as most of these hernias are diagnosed early in life. What is Known: • Inguinal hernia is one of the most common disorders encountered by a pediatric surgeon. • Prematurity increases the risk of inguinal hernia. What is New: • Children with congenital abdominal wall defects have a significantly higher risk of inguinal hernia than general population. • Families should be informed of this elevated hernia risk to avoid delays in seeking care.

Screening of hydrocephalus in infants using either WHO or population-based head circumference reference charts.

AIM: The aim was to compare the performances of the World Health Organization (WHO) and population-based (PB) references in the screening for hydrocephalus in infants aged <2 years. METHODS: We collected 341 longitudinal head circumference (HC) measurements of hydrocephalic infants and 120 181 measurements of 15 145 healthy infants from primary care. The measurements were converted into z-scores, and a new screening parameter, change in HC standard deviation score (SDS) over time (ΔHC SDS), was calculated. Comparisons were made using receiver operating characteristics analysis and linear mixed models. RESULTS: The mean HC SDSWHO was 3.5 and the mean HC SDSPB was 2.9 in the hydrocephalic infants, and in healthy children, those numbers were 1.0 SDSWHO and 0 SDSPB , respectively. The best screening accuracy was obtained with the PB reference in combination with the ΔHC SDS parameter (AUC 0.89). The accuracy of the WHO standard could be improved to a similar level by customising the screening cut-offs of HC SDS according to the population and combining screening parameters. CONCLUSIONS: Auxology alone was not sufficient for the screening of hydrocephalus. The WHO standard should be validated in the population, and population-specific cut-offs for normality defined before its introduction.

Different strategies, equivalent treatment approaches in terms of mortality in four university hospitals: a retrospective multicenter study of gastroschisis in Finland.

PURPOSE: Optimal treatment of gastroschisis is not determined. The aim of the present study was to investigate treatment methods of gastroschisis in four university hospitals in Finland. METHODS: The data of neonates with gastroschisis born between 1993 and 2015 were collected. The primary outcomes were short and long-term mortality and the length of stay (LOS). Statistical analyses consisted of uni- and multivariate models. RESULTS: Total of 154 patients were included (range from 31 to 52 in each hospital). There were no statistically significant differences in mortality or LOS between centers. Significant differences were observed between the hospitals in the duration of mechanical ventilation (p = 0.046), time to full enteral nutrition (p = 0.043), delay until full defect closure (p = 0.003), central line sepsis (p = 0.025), abdominal compartment syndrome (p = 0.018), number of abdominal operations during initial hospitalization (p = 0.000) and follow-up (p = 0.000), and ventral hernia at follow-up (p = 0.000). In a Cox multivariate analysis, the treating hospital was not associated with mortality. CONCLUSION: There were no differences in short or long-term mortality between four university hospitals in Finland. However, some inter-hospital variation in postoperative outcomes was present. LEVEL OF EVIDENCE: Level III.

Congenital abdominal wall defects and cryptorchidism: a population-based study.

PURPOSE: Several studies have reported high prevalence of undescended testis (UDT) among boys with congenital abdominal wall defects (AWD). Due to rarity of AWDs, however, true prevalence of testicular maldescent among these boys is not known. We conducted a national register study to determine the prevalence of UDT among Finnish males with an AWD. METHODS: All male infants with either gastroschisis or omphalocele born between Jan 1, 1998 and Dec 31, 2015 were identified in the Register of Congenital Malformations. The data on all performed operations were acquired from the Care Register for Health Care. The register data were examined for relevant UDT diagnosis and operation codes. RESULTS: We identified 99 males with gastroschisis and 89 with omphalocele. UDT was diagnosed in 10 (10.1%) infants with gastroschisis and 22 (24.7%) with omphalocele. Majority of these required an operation; 8/99 (8.1%) gastroschisis and 19/89 (21.3%) omphalocele patients. UDT is more common among AWD patients than general population with the highest prevalence in omphalocele. CONCLUSIONS: Cryptorchidism is more common among boys with an AWD than general population. Furthermore, omphalocele carries significantly higher risk of UDT and need for orchidopexy than gastroschisis. Due to high prevalence testicular maldescent, careful follow-up for UDT is recommended.

Finnish Parents' Responsibilities for Their Infant's Care When They Stayed in a Single Family Room in a Neonatal Intensive Care Unit.

PURPOSE: To describe parents' perceptions of their responsibilities for their infant's care during admission to a single family room in a neonatal intensive care unit (NICU). DESIGN AND METHODS: A qualitative study with semi-structured individual interviews conducted at a family-centered level III Finnish NICU in late 2016 and early 2017. The participants were 10 mothers and nine fathers of infants aged from six days to eight months. The data were analyzed with inductive content analysis. RESULTS: The parents wanted to take responsibility for their infant's care during their stay in a single family room in the NICU, because it prepared them for their infant's discharge. The mothers and fathers reported that their responsibilities supported them as they grew into parenthood and enabled their infants' rights. On the other hand, the parents needed nurses to empower them to commit to, and take, responsibility for their infant's care and share decision making. The nurses also taught the parents caring skills. CONCLUSIONS: Empowering parents to take responsibility enabled their infant's rights during their stay in a single family room in the NICU. More research is needed about how nurses transfer these responsibilities to parents and how those are connected to the infant's rights and well-being. PRACTICE IMPLICATIONS: Organizations who provide single family rooms in NICUs need to develop guidelines that facilitate the responsibilities that parents and nurses have to care for the infants. Although parents are the infant's primary caregivers, they depend on nurses to ensure their infant is safely cared for.

Sexual dimorphism in postnatal gonadotrophin levels in infancy reflects diverse maturation of the ovarian and testicular hormone synthesis.

BACKGROUND: The postnatal gonadotrophin surge is sexually dimorphic: FSH levels predominate in girls and LH levels in boys. However, in preterm (PT) girls, both gonadotrophin levels are higher than in PT boys. OBJECTIVE: To evaluate how gonadal maturation contributes to the sex differences in FSH and LH. DESIGN: Monthly follow-up of 58 full-term (FT, 29 boys) and 67 PT (33 boys) infants from 1 week (D7) to 6 months of age (M1-M6). Analyses were also carried out according to postmenstrual (PM) age in PT infants. METHODS: Urinary LH, FSH, oestradiol (E2), testosterone (T) and serum inhibin B (InhB) levels. RESULTS: High gonadotrophin levels in PT girls abruptly decreased (P < .001) by M2, corresponding to a PM age of 38-42 weeks, and LH levels fell below the levels found in boys. This decrease was parallel to a steep increase in E2 levels (P < .001), and, from M4 to M6, LH and E2 correlated positively in PT girls (P < .01). T levels in PT boys increased earlier than E2 levels in PT girls. In addition, InhB levels were high in PT boys already at D7, in contrast to low InhB in PT girls. InhB and FSH correlated negatively in the whole group (P < .001). CONCLUSIONS: Ovarian hormone synthesis is immature and incapable of responding to gonadotrophin stimulus before 38-42 PM weeks in PT girls, which may explain their highly elevated FSH and LH levels. The higher InhB levels in boys compared to girls may explain sexual dimorphism in FSH levels.

Maturation of oxycodone pharmacokinetics in neonates and infants: Oxycodone and its metabolites in plasma and urine.

AIMS: This study aimed to characterize the pharmacokinetics of oxycodone and its major metabolites in infants and covered the age range between extremely preterm neonates and 2-year-old infants. METHODS: Seventy-nine infants (gestational age 23-42 weeks; postnatal age 0-650 days) received intravenous oxycodone hydrochloride trihydrate at a dose of 0.1 mg kg-1 during or after surgery. Three to seven blood samples were taken from each infant, and plasma concentrations of oxycodone, noroxycodone, oxymorphone, and noroxymorphone were quantified. The unconjugated forms of these compounds were determined in urine collected after up to 24 or 48 h from 25 infants. Pharmacokinetics was determined using noncompartmental analysis and reported for six clinically relevant age groups based on postmenstrual age. RESULTS: Oxycodone pharmacokinetics changed markedly with patient age. Preterm neonates were found to have the highest pharmacokinetic variability out of the study population. In extremely preterm neonates (n = 6) median of elimination half-life was 8.8 h (range 6.8-12.5), in preterm (n = 11) 7.4 h (4.2-11.6), and in older neonates (n = 22) 4.1 h (2.4-5.8), all of which were significantly longer than that in infants aged 6-24 months (n = 12) 2.0 h (1.7-2.6). Median renal clearance was fairly constant in all age groups, whereas non-renal clearance markedly increased with age. Noroxycodone was the major metabolite in plasma and urine. CONCLUSIONS: Oxycodone elimination is slower and pharmacokinetic variability more pronounced in neonates when compared to older infants. These findings highlight the importance of careful dose titration for neonates.

[Finland is a pioneer in childhood growth monitoring--Is is evidence-based?]. / Suomi on lasten kasvunseurannan edelläkävijä--onko hyödyistä näyttöä?

In Finland, growth monitoring is a fundamental part of preventive child health care, aiming at an early detection of childhood illnesses as well as weight gain or loss. However, evidence-based studies on growth monitoring are practically lacking. Updated growth curves must be representative of the monitored population. Screening of Turner syndrome and celiac disease with novel growth monitoring methods could facilitate early diagnosis. Electronic health records provide an alternative to develop an automated growth monitoring program, which was found to be distinctly better than the manually orientated one in primary care. Systematic growth monitoring seems to be beneficial, although true population- based evidence on effectiveness is scarce.
