Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) among adolescents with obesity results in significant weight loss; however, depot-specific changes have been understudied. OBJECTIVE We hypothesized that visceral adipose tissue (VAT) reduction in adolescents undergoing RYGB would be greater than other depots and associated with improvement in cardiometabolic risk factors. SETTING Three specialized treatment centers in Sweden. METHODS Fifty-nine adolescents underwent dual x-ray absorptiometry before surgery and at 1, 2, and 5 years after RYGB. Changes in body composition in multiple depots (total fat, lean body, gynoid fat, android fat, subcutaneous adipose tissue, and VAT) and cardiometabolic risk factors were assessed using multiple linear regression analysis and generalized estimating equations adjusting for age, sex, and baseline risk factor levels. Data are presented as percent change (95% CI) with regression models showing slopes and estimated P values. RESULTS At 1 year post-RYGB, a significant reduction was observed across all body composition measures (P < .001) with the greatest reduction observed in VAT (-65.1% [-68.7, -61.8]). From year 1 to 5 years post-RYGB, a regain was observed in all depots except lean body mass (1.2% [.3, 2.7], P = .105). A sex-specific difference in overall trajectories was only observed in lean body mass with males consistently having higher mean levels. Change in VAT at 1 year correlated with change in triglycerides (slope: .21 mg/dL/kg, P = .034) and fasting plasma insulin (slope: 44 pmol/L/kg, P = .027). CONCLUSIONS Adiposity measures all decreased after RYGB but poorly predicted change in cardiometabolic risk. Despite significant reductions at 1 year, a steady regain was observed out to 5 years, with values still well below baseline. Further research should consider control group comparison and extended follow-up.

Abstract
Several epidemiological studies have described childhood obesity as a risk factor for atopic disease, particularly asthma. At the same time, this association seems to be more conflicting for allergic rhinitis, atopic dermatitis, and chronic urticaria. This article aims to deepen the possibility of a relationship between childhood obesity and allergic diseases. As regards asthma, the mechanical and inflammatory effects of obesity can lead to its development. In addition, excess adiposity is associated with increased production of inflammatory cytokines and adipokines, leading to low-grade systemic inflammation and an increased risk of asthma exacerbations. Allergic rhinitis, atopic dermatitis, food allergies, and chronic urticaria also seem to be related to this state of chronic low-grade systemic inflammation typical of obese children. Vitamin D deficiency appears to play a role in allergic rhinitis, while dyslipidemia and skin barrier defects could explain the link between obesity and atopic dermatitis. Starting from this evidence, it becomes of fundamental importance to act on body weight control to achieve general and allergic health, disentangling the detrimental link between obesity allergic diseases and childhood obesity. Further studies on the association between adiposity and atopy are needed, confirming the biologically active role of fat tissue in the development of allergic diseases and exploring the possibility of new therapeutic strategies.

Abstract
Osteogenesis Imperfecta (OI) is a heterogeneous group of inherited skeletal dysplasias characterized by bone fragility. The study of bone metabolism, in these disease, is problematic in terms of clinical and genetic variability. The aims of our study were to evaluate the importance of Vitamin D levels in OI bone metabolism, reviewing studies performed on this topic and providing advice reflecting our experience using vitamin D supplementation. A comprehensive review on all English-language articles was conducted in order to analyze the influence of vitamin D in OI bone metabolism in pediatric patients. Reviewing the studies, contradictory data were found on the relationship between 25OH vitamin D levels and bone parameters in OI, and in several studies the baseline levels of 25OH D were below the threshold value of 75 nmol/L. In conclusion, according to the literature and to our experience, we highlight the importance of adequate vitamin D supplementation in children with OI.

Abstract
PURPOSE To assess the growth plates of the knee in a healthy population of young adults and adolescents using DTI, and to correlate the findings with chronological age and skeletal maturation. METHODS A prospective, cross-sectional study to assess the tibial and femoral growth plates with DTI in 155 healthy volunteers aged between 14.0 and 21 years old. Echo-planar DTI with 15 directions and b value of 0 and 600 s/mm2 was performed on a 3 T whole-body scanner. RESULTS A relationship was observed between chronological age and most DTI metrics (fractional anisotropy, mean diffusivity, and radial diffusivity), tract length and volume. (No significant relationship could be seen for axonal diffusivity and tract length.) Subdivision according to skeletal maturation showed the greatest tract lengths and volumes seen in stage 4b and not 4a. The intra-observer agreement was significant (P = 0.01) for all the measured variables, but agreement varied (femur 0.53 - 0.98; tibia 0.58 - 0.98). Spearman's correlation showed a significant correlation for age (P = 0.05; P = 0.01) as well as for the fractional anisotropy value within all variables in both femur and tibia. Tract number and volume had a similar correlation with most variables, especially the DTI metrics, and would seem to be interchangeable. CONCLUSION The current study indicates that DTI metrics could be a tool to assess the skeletal maturation process of the growth plate and its activity. Tractography seems promising to assess the activity of the growth plate in a younger population but must be used with caution in the more mature growth plate.

Abstract
BACKGROUND Growth hormone (GH) affects metabolism and regulates growth in childhood. The most prominent feature of GH deficiency (GHD) in children is diminished height velocity that eventually leads to short stature. In adult-onset GHD, lean body mass (LBM) is reduced, and visceral fat mass (FM) increased. Beneficial effects of GH treatment on body composition in adults with GHD, including an increase in muscle mass and a decrease in FM, are well established. Relatively few studies have investigated the effects of GH treatment on the body composition of pediatric patients with idiopathic or hypothalamic-pituitary disease-associated GH deficiency. This systematic review aimed to summarize available evidence relating to the effects of GH treatment on body composition in children with GHD. METHODS The PubMed, Science Direct, Cochrane Trials, and Embase databases, were searched with keywords including "GH", "body composition", "children", and "growth hormone" for English-language articles, published between January 1999 and March 2021. Two reviewers independently evaluated the search results and identified studies for inclusion based on the following criteria: participants had a confirmed diagnosis of GHD (as defined in each study); participants were pediatric patients who were receiving GH or had stopped GH treatment, regardless of whether they were pre- or post-pubertal; the intervention was recombinant human GH (rhGH; somatropin); and outcomes included changes in body composition during or after stopping GH therapy. Data extracted from each study included study quality, study sample characteristics, study interventions, and body composition. Data on fat-free mass and LBM were combined into a single category of LBM. RESULTS Sixteen studies reporting changes in body composition (i.e., FM and LBM) associated with GH treatment in children with GHD were identified and included in the review. Collectively, these studies demonstrated that FM decreased, and LBM increased in response to GH replacement therapy. CONCLUSION Despite study limitations (i.e., potential effects of diet and physical activity were not considered), we concluded that a periodic body composition assessment is required to ensure that a satisfactory body composition is achieved during GH replacement therapy in children with GHD.

Abstract
BACKGROUND To demonstrate extended protection against meningococcal serogroup B (MenB) disease after MenB-FHbp (bivalent rLP2086) vaccination, this study evaluated immunopersistence through 26 months following MenB-FHbp boosting after 2 or 3 primary doses in adolescents. STUDY DESIGN This phase 3, open-label study was an extension of 3 phase 2 studies with participants aged 11-18 years randomized to receive primary MenB-FHbp vaccination following 1 of 5 dosing schedules or control. A booster dose was administered 48 months after the primary series. Immunopersistence through 48 months after the last primary dose (persistence stage) and 26 months postbooster (booster stage) was determined by serum bactericidal assays using human complement (hSBAs) against 4 vaccine-heterologous test strains. Safety evaluations included adverse events (AEs) and local and systemic reactions. RESULTS Overall, 698 and 304 subjects enrolled in the persistence and booster stages, respectively. hSBA titers declined in all groups during 12 months postprimary vaccination, then remained stable through 48 months. One month postbooster, 93.4-100.0% of subjects achieved hSBA titers ≥ lower limit of quantitation against each test strain; percentages at 12 and 26 months postbooster were higher than at similar time points following primary vaccination. Primary and booster MenB-FHbp vaccinations were well tolerated, with ≤ 12.5% of subjects reporting AEs during each stage. The most common local (reported by 84.4-93.8% of subjects) and systemic (68.8-76.6%) reactions to the booster were injection site pain and fatigue and headache, respectively; ≤ 3.7% of subjects reported severe systemic events. CONCLUSION Protective hSBA titers initially declined but were retained by many subjects for 4 years irrespective of primary MenB-FHbp vaccination schedule. Boosting at 48 months after primary vaccination was safe, well tolerated, and induced immune responses indicative of immunological memory that persisted through 26 months. Booster vaccination during late adolescence may prolong protection against MenB disease.

Abstract
Background Growth development is traditionally evaluated with plain radiographs of the hand and wrist to visualize bone structures using ionizing radiation. Meanwhile, MRI visualizes bone and cartilaginous tissue without radiation exposure. Purpose To determine the state of growth plate closure of the knee in healthy adolescents and young adults and compare the reliability of staging using cartilage sequences and T1-weighted (T1W) sequence between pediatric and general radiologists. Material and Methods A prospective, cross-sectional study of MRI of the knee with both cartilage and T1W sequences was performed in 395 male and female healthy subjects aged between 14.0 and 21.5 years old. The growth plate of the femur and the tibia were graded using a modified staging scale by two pediatric and two general radiologists. Femur and tibia were graded separately with both sequences. Results The intraclass correlation was overall excellent. The inter- and intra-observer agreement for pediatric radiologists on T1W was 82% (κ = 0.73) and 77% (κ = 0.65) for the femur and 90% (κ = 0.82) and 87% (κ = 0.75) for the tibia. The inter-observer agreement for general radiologists on T1W was 69% (κ = 0.56) for the femur and 56% (κ = 0.34) for the tibia. Cohen’s kappa coefficient showed a higher inter- and intra-observer agreement for cartilage sequences than for T1W: 93% (κ = 0.86) and 89% (κ = 0.79) for the femur and 95% (κ = 0.90) and 91% (κ = 0.81) for the tibia. Conclusion Cartilage sequences are more reliable than T1W sequence in the assessment of the growth plate in adolescents and young adults. Pediatric radiology experience is preferable.

Abstract
BACKGROUND Bone age assessment (BAA) is used in numerous pediatric clinical settings as well as in legal settings when entities need an estimate of chronological age (CA) when valid documents are lacking. The latter case presents itself as critical as the law is harsher for adults and granted rights along with imputability changes drastically if the individual is a minor. Traditional BAA methods have drawbacks such as exposure of minors to radiation, they do not consider factors that might affect the bone age, and they mostly focus on a single region. Given the critical scenarios in which BAA can affect the lives of young individuals, it is important to focus on the drawbacks of the traditional methods and investigate the potential of estimating CA through BAA. OBJECTIVE This study aims to investigate CA estimation through BAA in young individuals aged 14-21 years with machine learning methods, addressing the drawbacks of research using magnetic resonance imaging (MRI), assessment of multiple regions of interest, and other factors that may affect the bone age. METHODS MRI examinations of the radius, distal tibia, proximal tibia, distal femur, and calcaneus were performed on 465 men and 473 women (aged 14-21 years). Measures of weight and height were taken from the subjects, and a questionnaire was given for additional information (self-assessed Tanner Scale, physical activity level, parents' origin, and type of residence during upbringing). Two pediatric radiologists independently assessed the MRI images to evaluate their stage of bone development (blinded to age, gender, and each other). All the gathered information was used in training machine learning models for CA estimation and minor versus adult classification (threshold of 18 years). Different machine learning methods were investigated. RESULTS The minor versus adult classification produced accuracies of 0.90 and 0.84 for male and female subjects, respectively, with high recalls for the classification of minors. The CA estimation for the 8 age groups (aged 14-21 years) achieved mean absolute errors of 0.95 years and 1.24 years for male and female subjects, respectively. However, for the latter, a lower error occurred only for the ages of 14 and 15 years. CONCLUSIONS This study investigates CA estimation through BAA using machine learning methods in 2 ways: minor versus adult classification and CA estimation in 8 age groups (aged 14-21 years), while addressing the drawbacks in the research on BAA. The first achieved good results; however, for the second case, the BAA was not precise enough for the classification.

Abstract
Maternal lifestyle during pregnancy, as well as early nutrition and the environment infants are raised in, are considered relevant factors for the prevention of childhood obesity. Several models are available for the prediction of childhood overweight and obesity, yet most have not been externally validated. Moreover, the factors considered in the models differ among studies as the outcomes manifest after birth and depend on maturation processes that vary between individuals. The current Review examines and interprets data on the early determinants of childhood obesity to provide relevant strategies for daily clinical work. We evaluate a selection of prenatal and postnatal factors associated with child adiposity. Actions to be considered for preventing childhood obesity include the promotion of healthy maternal nutrition and weight status at reproductive age and during pregnancy, as well as careful monitoring of infant growth to detect early excessive weight gain. Paediatricians and other health-care professionals should provide scientifically validated, individual nutritional advice to families to counteract excessive adiposity in children. Based on systematic reviews, original papers and scientific reports, we provide information to help with setting up public health strategies to prevent overweight and obesity in childhood.

Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is an effective obesity treatment in adults and has become established in adolescents. Lower adherence to supplementation in adolescents confers a risk for long-term nutritional deficiencies. OBJECTIVES To assess adherence to supplementation, micronutrient intake, and biochemistry in adolescents through 5 years after RYGB. SETTING University hospitals, multicenter study, Sweden. METHODS Micronutrient intake and adherence to supplementation were assessed by diet history interviews and biochemistry preoperatively, 1, 2, and 5 years after RYGB in 85 adolescents (67% females), aged 16.5 years (± 1.2) with a body mass index of 45.5 kg/m2 (± 6.0). Adherence was defined as taking prescribed supplements ≥3 times a week. Micronutrient intake and biochemistry were compared with matched controls at 5 years. RESULTS Over 75% completed the dietary assessments across 5 years after RYGB. Adherence ranged between 44-61% through 5 years. At 5 years, ferritin and hemoglobin decreased (P < .04) and 61% had iron deficiency (P ≤ .001). Among females with iron deficiency, most did not adhere to supplementation (P = .005), and 59% of these had anemia (P < .001). Vitamin D insufficiency continued after surgery and 80% of participants who did not adhere to supplementation had insufficiency (P = .002). Adolescents not adhering had lower levels of vitamin D, B12, and ferritin (females) compared with both adhering adolescents and the control group (all P < .04). CONCLUSIONS Half of adolescents after RYGB reported sufficient long-term adherence to supplementation. Adhering to supplements and reporting a higher micronutrient intake were associated with more favorable biochemistry. Results support the recommendations for monitoring micronutrient intake and biochemistry in all patients who have undergone RYGB surgery, and the recommendation of higher preventive supplementation of vitamin D and iron in both sexes. As hypothesized, adolescents not adhering had a higher prevalence of long-term micronutrient deficiencies.

Abstract
BACKGROUND The duration of protection provided by varicella vaccines is unclear. We assessed the 10-year vaccine efficacy of two doses of a combined measles-mumps-rubella-varicella vaccine (MMRV), one live attenuated varicella vaccine (V) dose given after one measles-mumps-rubella vaccine (MMR) dose (MMR + V), versus two MMR doses (control vaccine) for the prevention of confirmed varicella. METHODS This was a phase 3b follow-up of an observer-blinded, randomised, controlled trial. In phase a, children aged 12-22 months (at first vaccination) from Czech Republic (Czechia), Greece, Italy, Lithuania, Norway, Poland, Romania, Russia, Slovakia, and Sweden were randomly assigned by computer-generated randomisation list (3:3:1) to receive two doses of MMRV, one dose of MMR and one dose of varicella vaccine, or two doses of MMR, 42 days apart. Varicella cases were confirmed by detection of viral DNA, or epidemiological link and clinical assessment, by an independent data monitoring committee; disease severity was based on a modified Vázquez scale. Hazard ratios for MMRV and MMR + V versus MMR estimated in the per-protocol cohort using a Cox proportional hazards regression model were used to calculate vaccine efficacy and 95% CI. Serious adverse events were recorded throughout the study in all vaccinated children. Study objectives were secondary and descriptive. The trial is registered at ClinicalTrials.gov, number NCT00226499. FINDINGS Between Sept 1, 2005, and May 10, 2006, 5803 children (mean age 14·2 months, SD 2·5) were vaccinated. The per-protocol cohort included 2279 children from the MMRV group, 2266 from the MMR + V group, and 744 from the MMR group. From baseline to a median follow-up of 9·8 years, 76 (3%) children in the MMRV group, 469 (21%) in the MMR + V group, and 352 (47%) in the MMR group had varicella. Vaccine efficacy against all varicella was 95·4% (95% CI 94·0-96·4) for MMRV and 67·2% (62·3-71·5) for MMR + V; vaccine efficacy against moderate or severe varicella was 99·1% (97·9-99·6) for MMRV and 89·5% (86·1-92·1) for MMR + V. During phase b, serious adverse events were reported by 290 (15%) of 1961 children in the MMRV group, 317 (16%) of 1978 in the MMR + V group, and 93 (15%) of 641 in the MMR group. There were no treatment-related deaths. INTERPRETATION The 10-years vaccine efficacy observed, suggests that a two-dose schedule of varicella vaccine provided optimum long-term protection for the prevention of varicella by offering individual protection against all severities of disease and leading to a potential reduction in transmission, as observed in the US experience with universal mass vaccination.

Abstract
BACKGROUND Information is scarce on long-term changes in energy intake (EI), dietary energy density (DED), and body composition in adolescents undergoing laparoscopic Roux-en-Y gastric bypass (RYGB). OBJECTIVES To investigate long-term changes in EI, DED, and body composition in adolescents after LRYGB. SETTING University hospitals, multicenter study, Sweden. METHODS Eighty-five adolescents (67% girls; mean ± standard deviation, age 16.0 ± 1.2 yr, body mass index 45.5 ± 6.1 kg/m2) were assessed preoperatively (baseline) and 1, 2, and 5 years after LRYGB with diet history interviews and dual-energy x-ray absorptiometry. Matched obese adolescent controls receiving nonsurgical treatment were assessed only at 5 years. RESULTS Weight decreased 31%, 33%, and 28% at 1, 2, and 5 years after LRYGB (P < .001) while controls gained 13% over 5 years (P < .001). Dietary assessments were completed in 98%, 93%, 87%, and 75% at baseline and 1, 2, and 5 years, respectively, and in 65% of controls. Baseline EI (2558 kcal/d), decreased by 34%, 22%, and 10% after 1, 2, and 5 years (P < .05). DED decreased at 1 year (P = .03). Macronutrient distribution was not different from controls at 5 years, but EI and DED were 31% and 14% lower (P < .015). Fat, fat-free, and muscle mass decreased through 5 years after LRYGB (P < .001). Boys preserved muscle mass more than girls (P < .01). Adequate protein intake was associated with preservation of muscle mass (P = .003). CONCLUSIONS In adolescents undergoing LRYGB EI remained 10% lower 5 years after surgery. Decreased EI and DED, rather than macronutrient distribution, are important factors in weight loss after surgery. Higher protein intake may facilitate preservation of muscle mass.

Abstract
The impact of childhood obesity on the Swedish Health Care system is described. Childhood Obesity and Diabetes Type 2 is increasing for the last 10 years, but not Diabetes Type 1. Thus, prevention is needed. How to define prevention of obesity? Could treatment of childhood obesity be regarded as prevention of adult obesity? Of course it could, but we are lacking a long term follow-up from childhood to adulthood. However, we know that childhood obesity is a risk factor for adult disease. But we need long-lasting results in children to being able to state that we have prevented adult obesity. What about treatment of children with overweight, i.e. defined as the less severe level of an increased body weight as opposed to obesity? There are few if any studies restricting the treatment only to overweight children. Normally, obese children are treated, and some overweight children are added usually to increase the study sample. Then of course promotion of a healthy lifestyle could be of major interest. Finally, the traditional concept of primary prevention seems to be the only solution that is realistic according to many. However, there is no clear pattern when primary prevention works.

Abstract
BACKGROUND We have previously shown promising results 2 years after Roux-en-Y gastric bypass surgery, within the Adolescence Morbid Obesity Surgery study (AMOS). The aim of the current study was to describe the 2-year outcome in cardiorespiratory fitness, body composition, and functional capacity in the Stockholm subset of the AMOS study. METHODS Forty-one adolescents (10 male, 31 female, age 14-18 years, body mass index 35-69 kg·m-2) were included. In addition to anthropometric measurements, participants performed a submaximal bicycle test, 6-min walk test, dual-energy X-ray absorptiometry, and a short interview at baseline, 1 and 2 years after surgery. RESULTS Relative improvements in maximal oxygen consumption (VO2max) per kilogram body mass (+62 %) and per kilogram fat-free mass (+21 %), as well as walking distance (+13 %) were observed after 1 year, and persisted 2 years after surgery. Despite a reduction of fat-free mass (-15 %), absolute VO2max was maintained across the full group (+8 %, p = ns) and significantly increased in non-smokers. Body mass and fat mass were significantly decreased (-45.4 and -33.3 kg, respectively). Self-reported physical activity was significantly increased, and pain associated with movement was reduced. CONCLUSIONS In adolescents with obesity, Roux-en-Y gastric bypass improved VO2max more than could be explained by fat mass loss alone. In combination with improved functional capacity and body composition, these results suggest that surgery in adolescence might add specific benefits of importance for future health.

Abstract
BACKGROUND Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservatively treated adolescents and of adults undergoing Roux-en-Y gastric bypass, in the Adolescent Morbid Obesity Surgery (AMOS) study. METHODS We did a nationwide, prospective, non-randomised controlled study of adolescents (aged 13-18 years) with severe obesity undergoing Roux-en-Y gastric bypass at three specialised paediatric obesity treatment centres in Sweden. We compared clinical outcomes in adolescent surgical patients with those of matched adolescent controls undergoing conservative treatment and of adult controls undergoing Roux-en-Y gastric bypass. The primary outcome measure was change in BMI over 5 years. We used multilevel mixed-effect regression models to assess longitudinal changes. This trial is registered with ClinicalTrials.gov, number NCT00289705. FINDINGS Between April, 2006, and May, 2009, 100 adolescents were recruited to the study, of whom 81 underwent Roux-en-Y gastric bypass (mean age 16·5 years [SD 1·2], bodyweight 132·8 kg [22·1], and BMI 45·5 kg/m2 [SD 6·1]). 80 matched adolescent controls and 81 matched adult controls were enrolled for comparison of outcomes. The change in bodyweight in adolescent surgical patients over 5 years was -36·8 kg (95% CI -40·9 to -32·8), resulting in a reduction in BMI of -13·1 kg/m2 (95% CI -14·5 to -11·8), although weight loss less than 10% occurred in nine (11%). Mean BMI rose in adolescent controls (3·3 kg/m2, 95% CI 1·1-4·8) over the 5-year study period, whereas the BMI change in adult controls was similar to that in adolescent surgical patients (mean change -12·3 kg/m2, 95% CI -13·7 to -10·9). Comorbidities and cardiovascular risk factors in adolescent surgical patients showed improvement over 5 years and compared favourably with those in adolescent controls. 20 (25%) of 81 adolescent surgical patients underwent additional abdominal surgery for complications of surgery or rapid weight loss and 58 (72%) showed some type of nutritional deficiency; health-care consumption (hospital attendances and admissions) was higher in adolescent surgical patients compared with adolescent controls. 20 (25%) of 81 adolescent controls underwent bariatric surgery during the 5-year follow-up. INTERPRETATION Adolescents with severe obesity undergoing Roux-en-Y gastric bypass had substantial weight loss over 5 years, alongside improvements in comorbidities and risk factors. However, gastric bypass was associated with additional surgical interventions and nutritional deficiencies. Conventional non-surgical treatment was associated with weight gain and a quarter of patients had bariatric surgery within 5 years.

Abstract
BACKGROUND Neisseria meningitidis serogroup B (MnB) is a leading cause of invasive meningococcal disease in adolescents and young adults. A recombinant factor H binding protein (fHBP) vaccine (Trumenba(®); bivalent rLP2086) was recently approved in the United States in individuals aged 10-25 years. Immunogenicity and safety of 2- or 3-dose schedules of bivalent rLP2086 were assessed in adolescents. METHODS Healthy adolescents (11 to <19 years) were randomized to 1 of 5 bivalent rLP2086 dosing regimens (0,1,6-month; 0,2,6-month; 0,2-month; 0,4-month; 0,6-month). Immunogenicity was assessed by serum bactericidal antibody assay using human complement (hSBA). Safety assessments included local and systemic reactions and adverse events. RESULTS Bivalent rLP2086 was immunogenic when administered as 2 or 3 doses; the most robust hSBA responses occurred with 3 doses. The proportion of subjects with hSBA titers ≥1:8 after 3 doses ranged from 91.7% to 95.0%, 98.9% to 99.4%, 88.4% to 89.0%, and 86.1% to 88.5% for MnB test strains expressing vaccine--heterologous fHBP variants A22, A56, B24, and B44, respectively. After 2 doses, responses ranged from 90.8% to 93.5%, 98.4% to 100%, 69.1% to 81.1%, and 70.1% to 77.5%. Geometric mean titers (GMTs) were highest among subjects receiving 3 doses and similar between the 2- and 3-dose regimens. After 2 doses, GMTs trended numerically higher among subjects with longer intervals between the first and second dose (6 months vs 2 and 4 months). Bivalent rLP2086 was well tolerated. CONCLUSIONS Bivalent rLP2086 was immunogenic and well tolerated when administered in 2 or 3 doses. Three doses yielded the most robust hSBA response rates against MnB strains expressing vaccine-heterologous subfamily B fHBPs.

Abstract
BACKGROUND About 20% of adolescents experience substantial mental health problems after bariatric surgery. OBJECTIVES The aim of this study was to explore differences between adolescents with poor mental health (PMH) 2 years after surgery and those with average/good mental health. SETTING Three university hospitals in Sweden. METHODS Mental health and health-related quality of life were assessed in 82 of 88 adolescents (mean age: 16.8 yr, 67% female) at baseline and 1 and 2 years after laparoscopic gastric bypass. Possible associations among mental health, weight, and biochemical outcomes were explored. RESULTS Two years after surgery 16 (20%) adolescents were identified as having PMH. More symptoms of anxiety and depression and worse mental health at baseline significantly predicted PMH 2 years later. The decline in mental health for the PMH group happened mainly during the second year after surgery. Suicidal ideation was reported in 14% of the total sample 2 years postsurgery and was more frequent in the PMH group. Weight outcomes between groups were comparable at all time points, and physical health was equally improved 2 years after surgery. CONCLUSIONS Although adolescents with PMH after surgery lose as much weight and have similar improvements in physical health compared with other adolescents, special attention should be given to adolescents who report mental health problems at baseline and follow-up, especially during the second year after gastric bypass. The high prevalence of suicidal ideation in adolescents 2 years after bariatric surgery is another indication that longer follow-up is necessary.

Abstract
OBJECTIVE This study aimed to evaluate changes in mental health over 2 years in adolescents undergoing gastric bypass. METHODS Eighty-eight adolescents (65% girls) aged 13 to 18 years were assessed at baseline and 1 and 2 years after surgery. Generic and obesity-specific questionnaires were used to evaluate outcomes in mental health, also in relation to age- and gender-specific norms. RESULTS Symptoms of anxiety (P = 0.001), depression (P = 0.001), anger (P = 0.001), and disruptive behavior (P = 0.022) were significantly reduced at 2 years after surgery, as were obesity-related problems (P < 0.001). Self-esteem (P < 0.001), self-concept (P < 0.001), and overall mood (P = 0.025) improved significantly. Improvements were mainly observed during the first year after surgery. The second year was characterized by stabilization. Symptoms of anxiety, depression, anger, disruptive behavior, and self-concept were at normative levels after surgery. However, 19% of the adolescents had depressive symptoms in the clinical range. CONCLUSIONS A substantial improvement in mental health in adolescents over the first 2 years after gastric bypass was found. Most adolescents had a level of mental health and self-concept similar to norms, but a marked subgroup showed substantial depressive symptoms 2 years after surgery.

Abstract
The Child Feeding Questionnaire (CFQ) assesses parental feeding attitudes, beliefs and practices concerned with child feeding and obesity proneness. The questionnaire has been developed in the U.S., and validation studies in other countries are limited. The aim of this study was to examine the psychometric properties of the CFQ in Sweden and the associations between parenting practices and children's weight status. Based on records from the Swedish population register, all mothers of 4-year-olds (n = 3007) from the third largest city in Sweden, Malmö, were contacted by mail. Those who returned the CFQ together with a background questionnaire (n = 876) received the CFQ again to enable test-retest evaluation; 564 mothers completed the CFQ twice. We used confirmatory factor analysis to test whether the original 7-factor model was supported. Good fit (CFI = 0.94, TLI = 0.95, RMSEA = 0.04, SRMR = 0.05) was obtained after minor modifications such as dropping 2 items on restriction and adding 3 error covariances. The internal reliability and the 2-week test-retest reliability were good. The scores on restriction were the lowest ever reported. When the influence of parenting practices on child BMI (dependent variable) was examined in a structural equation model (SEM), child BMI had a positive association with restriction and a negative association with pressure to eat. Restriction was positively influenced by concern about child weight. The second SEM treated parenting practices as dependent variables. Parental foreign origin and child BMI had direct effects on restriction, while pressure to eat was also influenced by parental education. While the results of the study support the usefulness of the CFQ in Sweden, carefully designed cross-cultural comparisons are needed to explain why the levels of restrictive feeding in Swedish families are the lowest reported.

Abstract
In this paper, we address surgical aspects on bariatric surgery in adolescents from a nationwide Swedish study. Laparoscopic gastric bypass surgery was performed for 81 adolescents with morbid obesity (13-18 years), while 81 adolescents with obesity-matched by age, sex, and BMI received conventional care. Another comparison group was adults undergoing gastric bypass at the same institution during the same time period. This report addresses the 2-year clinical outcome and five-year surgical adverse event rate. Body weight decreased from 133 kg (SD = 22) at inclusion to 92 kg (SD = 17) after 1 year and was 89 (SD = 18) after 2 years (p < 0·001) representing a 32% (-35 to -30) weight loss after 2 years, corresponding to 76% (-81 to -71) excess weight loss. Weight loss was similar in the adult gastric bypass patients (-31%) while weight gain (+3%) was seen in the conventionally treated obese adolescents. Significant improvement in cardiovascular and metabolic risk factors and inflammation was seen after surgery. The treatment was generally well tolerated and quality of life improved significantly. The surgical adverse events included cholecystectomies (10%) and operations for internal hernia (9%) but no postoperative mortality. Adolescents undergoing laparoscopic gastric bypass surgery achieve similar weight loss to adults. Improvements in risk factors and quality of life were substantial. There were surgical complications similar to the adult group, which may be preventable.

Abstract
Introduction A new treatment plan was implemented at Skåne University Hospital, on economic grounds, for children requiring recombinant human growth hormone (rhGH) treatment. This involved switching patients from treatment with originator rhGHs to treatment with a biosimilar rhGH, somatropin (Omnitrope®), using a Dialogue Teamwork approach. The feasibility of using this approach to implement the switch of treatment was assessed, as well as the impact of the switch on treatment efficacy and cost of therapy. Methods As part of the Dialogue Teamwork approach, patients/parents received several opportunities for dialogue and sources of information, including discussions with the Head of Department, the responsible physician and a specialized endocrinology nurse. Height and height standard deviation score (HSDS) data were plotted for each individual patient (N = 98). A modeling approach was also used, to predict growth after switching to biosimilar rhGH; the predictions were then compared to the actual observed height after the switch. Costs to the clinic of rhGH therapy were calculated between May–August 2009 and May–August 2012. Results Of the 102 patients offered the switch, 98 accepted. Height and HSDS data indicated there was no negative impact on growth velocity after the switch to biosimilar rhGH. Modeling demonstrated that observed growth following the switch was consistent with predicted growth based on data before patients were switched. There were no reports of serious or unexpected adverse drug reactions following the switch to biosimilar rhGH. Following the switch, the cost to the clinic of rhGH treatment decreased from approximately 6 million SEK (May–August 2009) to approximately 4 million SEK (May–August 2012). This corresponds to an annual saving of 6 million SEK (€650,000). Conclusion Patients were successfully switched from originator to biosimilar rhGH (somatropin), with no negative impact on growth, and no serious or unexpected adverse drug reactions. The switch from originator to biosimilar rhGH is associated with substantial cost savings.

Abstract
Bariatric surgery is suggested as a treatment option for severely obese adolescents. Because adolescence is characterized by intense psychosocial adjustment and development, it is important to study the effect of this procedure on adolescents' psychological health. This study examined baseline status and short-term changes in anxiety, depression, anger, disruptive behavior, and self-concept in 37 adolescents (mean age 16.6 ± 1.3). Participants completed the Beck Youth Inventories (BYI) at inclusion and (on average) 4 months after undergoing Roux-en-Y gastric bypass (RYGB). Internalizing (anxiety and depression) and externalizing (anger and disruptive behavior) symptoms were higher at baseline than gender-specific norms. One fifth had a very low self-concept. Four months after surgery, the adolescents showed significantly fewer symptoms of anxiety and depression and significantly improved self-concept from baseline. Anger and disruptive behavior showed no significant changes. An analysis of clinically meaningful changes was conducted, and besides the overall positive outcome, 16% (n = 6) of the adolescents had deteriorated on two or more inventories in BYI shortly after surgery. This impaired group did not show any specific features at inclusion. The results indicate the importance of psychological monitoring immediately after bariatric surgery and the need for additional psychosocial support to be available for vulnerable sub-groups of adolescents. Further studies with larger samples are necessary to identify characteristics predictive of short-term adverse psychological outcomes in adolescents after bariatric surgery.

Abstract
The co-administration of the tetravalent meningococcal conjugate vaccine, MenACWY-TT, with a licensed hepatitis A and B vaccine, HepA/B (Twinrix(®)), was compared to their separate administration in this open, randomised, controlled study. Healthy subjects 11-17 years of age (n=611) were randomised (3:1:1) to receive both vaccines, MenACWY-TT alone or HepA/B alone. The co-administration of both vaccines was shown to be non-inferior to their individual administration. At seven months after the first vaccination, 99.4-100% of the subjects who received both vaccines co-administered showed seroprotection against all meningococcal serogroups and at least 99.1% of them were seropositive for hepatitis A and seroprotected against hepatitis B. This study suggests that MenACWY-TT vaccine could be co-administered with HepA/B without adversely impacting the immunogenicity, safety and reactogenicity of either of the vaccines.

Abstract
More than 15 percent of children in Europe are overweight; another 5 percent are obese. The high prevalence of obesity emphasizes the necessity of developing evidence-based treatment programs that are useful in a clinical setting. Management of childhood obesity is commonly based on lifestyle interventions where nutrition, physical activity, and behavior modification are the main targets. To incorporate lifestyle interventions, many childhood obesity treatment models use different psychological models, such as behavior modification or cognitive behavior therapy. This paper presents the key lessons from a research program on an empirically supported family-therapy-based treatment, Standardized Obesity Family Therapy (SOFT). SOFT is based on systemic and solution-focused theories and has shown positive effects on the child with respect to degree of obesity, physical fitness, self-esteem, and family functioning in several studies. The distinguishing features of SOFT are the focus on family interactions as an important source for implementing and maintaining lifestyle changes, the multidisciplinary team approach, and a limited number of sessions (three to four per year). The main aim of this paper is to provide tools for clinicians in the field of obesity who work with families, alone or in a multidisciplinary team.

Abstract
Aims: Although childhood obesity is becoming increasingly prevalent, treatment options are limited and the continued development of effective treatment strategies is necessary. It is equally important to explore involvement of other resources in society, such as sports associations. This study was designed to investigate the possibility of reducing the degree of obesity in obese children by focusing on physical activity as an intervention. Methods: Seventy-six children (40 boys) aged 8—12 years (mean age 10.5 years, mean body mass index (BMI) 28.9, standard deviation (SD) 3.0; mean BMI z-score 3.24, SD 0.49) were invited to participate in a one-week sports camp and six-month support system. After the camp a sports coach from a local sports club supported the child during participation in a chosen sport for six months. Weight, height, body composition (using dual energy x-ray absorptiometry and magnetic resonance imaging), and lifestyle (using a questionnaire) were measured at baseline and after 12 months. Data were pooled from two camps, one with a self-selected control group and one randomized controlled trial. Results: Twelve months after the camp the intervention group had a significant decrease in BMI z-score (baseline BMI z-score 3.22; follow up 3.10, p = 0.023). The control group also reduced their BMI z-score (baseline BMI z-score 3.27; follow up 3.18, p = 0.022). No differences were found in baseline values, follow-up values, or changes in BMI z-score between groups, nor between boys and girls. Conclusions: The focus on physical activity as an intervention had no effect on degree of obesity when compared with a waiting list control group.

Abstract
OBJECTIVE The aim was to evaluate the efficacy of a Family Weight School treatment based on family therapy in group meetings with adolescents with a high degree of obesity. METHODS Seventy-two obese adolescents aged 12-19 years old were referred to a childhood obesity center by pediatricians and school nurses and offered a Family Weight School therapy program in group meetings given by a multidisciplinary team. Intervention was compared with an untreated waiting list control group. Body mass index (BMI) and BMI z-scores were calculated before and after intervention. RESULTS Ninety percent of the intervention group completed the program (34 boys, 31 girls; baseline age = 14.8 +/- 1.8 years [mean +/- standard deviation, SD], BMI = 34 +/- 4.0, BMI z-score = 3.3 +/- 0.4). In the control group 10 boys and 13 girls (baseline age = 14.3 +/- 1.6, BMI = 34.1 +/- 4.8, BMI z-score = 3.2 +/- 0.4) participated in the 1-year follow-up. Adolescents in the intervention group with initial BMI z-score < 3.5 (n = 49 out of 65, baseline mean age = 14.8, mean BMI = 33.0, mean BMI z-score = 3.1), showed a significant decrease in BMI z-scores in both genders (-0.09 +/- 0.04, p = 0.039) compared with those in the control group with initial BMI z-score < 3.5 (n = 17 out of 23, mean baseline age = 14.1, mean baseline BMI = 31.6, mean baseline BMI z-score = 3.01). No difference was found in adolescents with BMI z-scores > 3.5. CONCLUSIONS Family Weight School treatment model might be suitable for adolescents with BMI z-score < 3.5 treated with a few sessions in a multidisciplinary program.

Abstract
A dramatic increase in prevalence of pediatric obesity has occurred in most countries over the past few decades. This is of particular significance given the fact that overweight children and adolescents are at increased risk for multiple medical co-morbidities, as well as psychosocial and behavioral difficulties. While considerable attention has recently been paid to identifying obesity and the importance of associated co-morbidities, there has been less focus on considerations related to effective interventions. Interventions aimed at childhood obesity include prevention and treatment. Both prevention and treatment need improvement to be useful in the clinical setting. Few investigators have demonstrated that treatment is effective. The aim of this review is to examine the effectiveness of family-based interventions in obese pediatric subjects and to explore what specific components of family-based programs are of particular significance when treating obese children. A literature search was performed and relevant studies are presented. A majority of the studies support the use of family-based treatment. Furthermore, to develop a fully interactive model, more focus is needed on the specific techniques used in evidence-based programs.

Abstract
AIMS To study the influence of low-intensity solution-focused family therapy with obese and extremely obese pediatric subjects on body mass index (BMI) z-scores and self-esteem. MATERIALS AND METHODS Fifty-four obese children, aged 6-17 years, were referred to an outpatient obesity clinic. The families received solution-focused family therapy provided by a multidisciplinary team. Height and weight were recorded; BMI and BMI z-scores were derived. Self-esteem was assessed with a validated questionnaire, "I Think I Am." Parents completed "The Family Climate Scale" assessing family dynamics. RESULTS Eighty-one percent of the children (n =44, mean age 11.9 years, mean BMI z-score 3.67, range 2.46-5.48) and their parents participated in the follow-up. Eleven children were treated for 6-12 months, and 33 for more than 12 months. On average, the families received 3.8 family therapy sessions. Intervention resulted in a mean decrease in BMI z-score of 0.12 (p =0.0001). Self-esteem on the global scale improved after intervention (p =0.002), and also on sub-scales, depicting physical characteristics (p <0.001), psychological well-being (p =0.026), and relations with others (p =0.046). The Family Climate Scale showed improvement in the sub-scales for Expressiveness (p = 0.002) and Chaos (p =0.002). CONCLUSIONS Solution-focused family therapy provided by a multidisciplinary team to obese and extremely obese children may prove useful in the clinical setting, with a positive impact on obesity and self-esteem.

Abstract
OBJECTIVE A refrigerator-stable formulation of ProQuad has been developed to expand the utility of ProQuad to areas in which maintenance of a frozen cold chain (-15 degrees C or colder) during storage and transport may not be feasible. The objective of this study was to demonstrate that the immunogenicity and safety profiles of a refrigerator-stable formulation of ProQuad are similar to the recently licensed frozen formulation. METHODS In this double-blind, randomized, multicenter study, healthy 12- to 23-month-old children with negative vaccination and clinical histories for measles, mumps, rubella, varicella, and zoster were vaccinated with either the refrigerator-stable formulation of ProQuad (N = 1006) or the frozen formulation of ProQuad (N = 513). Patients were followed for 42 days after vaccination for adverse experiences. Immunogenicity was evaluated 6 weeks after vaccination. RESULTS The refrigerator-stable formulation of ProQuad was generally well tolerated. The incidence of adverse experiences was similar between groups. No vaccine-related serious adverse experiences were reported. For both groups, the response rate was > or = 97.7% for measles, mumps, and rubella, and the percentage of patients with a varicella zoster virus antibody titer of > or = 5 U/mL glycoprotein antigen-based enzyme-linked immunosorbent assay after vaccination was > or = 88.8%. The geometric mean titers for all antigens were numerically slightly higher in patients who received the refrigerator-stable formulation. CONCLUSIONS The refrigerator-stable formulation of ProQuad is generally well tolerated, highly immunogenic, and noninferior in terms of postvaccination antibody responses. This refrigerator-stable formulation may improve ease of vaccine administration, increase use of the vaccine throughout the world because of its improved storage conditions, and replace the frozen formulation of ProQuad or any dose of M-M-RII and Varivax in routine practice.

Abstract
OBJECTIVE Firstly, is the negative psychological effect of obesity also present in the whole population of obese and overweight children? Secondly, what tools could be recommended to measure the psychological effects of obesity? DESIGN Review. METHODS Quality of life or self-esteem is often used in evaluating the psychological effects of obesity. Test instruments used have been instruments for measuring quality of life such as the pediatric quality of life inventory (PedsQL) or the KINDL instrument, and measurements of self-esteem, such as 'ITIA' ('I think I am) and the Self-Perception Profile for Children. RESULTS The obese child studied in community samples has better quality of life and self-esteem than obese children from clinical samples. CONCLUSION Psychosocial factors seem to be more important than the functional limitations of obesity itself. This means that we might help the obese child better by social support to a minor part of the population than to focus on the child's obesity as a cause of psychological problems. A happy obese child might have greater resources to cope with the problem than previously thought.

Abstract
BACKGROUND In the last 15 y there has been a tremendous increase in the number of studies on pediatric obesity looking at epidemiology, health-related risks, etiology, methodology and treatment. During the early 1990s, the European Childhood Obesity Group (ECOG) was born as a group of scientists' expert in the field of pediatric obesity. ECOG this year celebrates the approach to early maturity with an excited and omni-comprehensive program developing through eight different tracks. METHODS Comments on different 'key' papers in each of the eight tracks. RESULTS The eight tracks were (1) Nutrition requirements and food habits, (2) physical activity, (3) prevention and political actions/strategies, (4) diabetes, (5) metabolism, (6) psychology, (7) pathology, and (8) treatment with emphasis on drugs. CONCLUSION Looking at the overall picture of the ECOG workshop we could conclude that despite the fact that childhood obesity is a crisis facing worldwide youth, it is necessary that action to control it must be taken now. All the six relevant levels (ie, family, schools, health professionals, government, industry and media) could be involved in prevention of child and adolescent obesity.

Abstract
Obesity is increasing in childhood and has approximately doubled during the last 10 years. Nowadays, more politicians and researchers find it necessary to start treating childhood obesity. The reasons for this are the high costs of obesity and its complications later in life-complications that also appear when obesity starts in childhood. In the following article, I will give a review of the treatments available that have been evaluated in studies. There are no relevant studies regarding surgery and medication in children. Thus, I will not comment further on those treatments. The treatment of choice is thus a change in lifestyle. To be able to help patients do this, you have to be professional when you encounter the patient. The best way to be successful is to use psychological treatments as described in this paper.

Abstract
To reduce the number of injections needed to comply with paediatric vaccination requirements, a liquid, hexavalent vaccine (DTaP-IPV-PRP-T-HBs; Hexavac; Aventis Pasteur MSD) has been developed for primary and booster vaccination of infants and toddlers. In extensive clinical studies, Hexavac has been shown to be highly immunogenic. Seroconversion or seroprotective titres of antibodies against all antigens were achieved in the majority of infants following a primary series of three doses administered at 1-2-month intervals from 2 months of age. Hexavac also induced immunologic memory, as evidenced by the anamnestic response to booster vaccination at 12-18 months of age. These responses were comparable with those seen following concomitant administration of Pentavac (DTaP-IPV//PRP-T) and monovalent hepatitis B vaccine (H-B-Vax II), and were also within the ranges observed for other relevant licensed vaccines. Clinical studies comparing the immunogenicity of Hexavac administered at either 2, 3 and 4 months or 2, 4 and 6 months demonstrated that it can be used by either vaccination schedule. A further study also supported the use of primary doses of Hexavac at 3 and 5 months with a booster at 12 months of age. Hexavac demonstrated a good reactogenicity and tolerability profile. The most frequently reported adverse events after both primary and booster doses were local reactions of redness and swelling/induration and a systemic response of mild fever, irrespective of the vaccine used for priming. Hexavac provided immunity against six important childhood diseases with a single injection at each visit.

Abstract
By observing and analyzing the influence of the therapist on the family as well as interactions between family members, the encounter with a family in a medical setting can serve to improve the health of its members, by improving their ability to use their own resources. This method of focusing on the interaction between individuals in a family or other systems has been a valuable addition to medical treatment of chronic disease. Family therapy has been shown to effectively improve treatment of diabetes, asthma and obesity. A review of the literature is presented.

Abstract
AIM Schoolchildren aged 10-11 with a family history of premature coronary artery disease (CAD), were examined in order to identify children with genetically determined dyslipidemias and a combination of risk factors. METHODS A total of 4000 questionnaires were distributed by the school; 55% of the families answered and returned the questionnaire. Blood lipids, apolipoprotein B, and Lp(a) lipoprotein were analysed in high risk children and their parents. RESULTS A family history of premature CAD in parents or grandparents was identified in 208 families; 175 agreed to take part in a clinical examination and laboratory tests. Normal blood lipid tests were found in 89 children. Another 48 had an isolated increase of Lp(a) lipoprotein of minor clinical importance. Of the remaining 38 children, 23 had non-hereditary abnormalities of low (LDL) or high density lipoprotein (HDL) cholesterol or apolipoprotein B. Fifteen children were suspected to have genetically determined dyslipidemias or a combination of risk factors: in four, possible familial hypercholesterolaemia (FH); in five, possible familial combined hyperlipidaemia; in three, hereditary low HDL cholesterol; and in three a combination of high LDL cholesterol and Lp(a) lipoprotein concentrations. In addition, possible FH was detected in eight of the parents. CONCLUSION It is worthwhile asking parents about the occurrence of premature CAD among their child's closest relatives.

Abstract
BACKGROUND The purpose of this study was to evaluate the ultrasound technique for measuring subcutaneous adipose tissue in infants. METHODS Twenty infants were investigated at 3, 6, and 12 months of age. All measurements were made by the same investigator in triplicate on the left side of the body at the triceps and subscapular anatomic landmarks and at the abdomen and thigh. An ultrasound system equipped with a linear 7.0-MHz transducer was used. RESULTS The intraclass correlation coefficients were 0.88 to 0.99. Random errors ranged from 0.01 to 0.19 mm. For log-transformed values, the random error ranged from 2.4% to 5.7%. CONCLUSIONS Measurements of subcutaneous fat in infants using ultrasound are reproducible when performed by the same observer.

Abstract
OBJECTIVE The objective of this study was to evaluate whether a regular formula for premature infants supplemented with nucleotides has any influence on plasma lipids and erythrocyte membrane fatty acids. METHODS Preterm infants fed either human milk supplemented with human milk protein (HM, n = 14), nucleotide-supplemented preterm formula (NF, n = 13), or a regular preterm formula (F, n = 13) were included in the study. The NF was supplemented with 18.2 mg cytidine monophosphate/l (CMP), 7.0 mg uridine monophosphate/l (UMP), 6.4 mg adenosine monophosphate/l (AMP), 3.0 mg inosine monophosphate/l (IMP) and 3.0 mg guanosine monophosphate/l (GMP). RESULTS There were significantly higher concentrations of triglycerides (TG) in infants fed NF compared to those fed F (191.42 +/- 79.58 vs 108.21 +/- 43.73, p < 0.001, mean +/- SD lipid concentrations, mg/100 ml plasma). Infants fed F had significantly lower concentrations of total cholesterol (94.34 +/- 11.71 vs 115.69 +/- 39.29, p < 0.01) and TG in plasma (108.21 +/- 43.73 vs 172.27 +/- 68.19, p < 0.001, mean +/- SD lipid concentrations, mg/100 ml plasma) when compared to HM-fed infants. There were no significant differences in any of the erythrocyte membrane fatty acids and total long-chain polyunsaturated fatty acids (LC-PUFA) between NF and F during the study period (6 weeks). Furthermore, total LC-PUFA and docosahexaenoic acid (DHA) concentrations in red blood cell were not significantly different when infants fed NF were compared to those fed HM. In contrast, however, infants fed F had significantly lower concentrations of total n-3 LC-PUFA (p < 0.01) and DHA (p < 0.01) than those found in HM-fed infants. CONCLUSIONS These results do not suggest an effect of nucleotides on the red blood cell LC-PUFA profile in preterm infants. However, the nucleotides may increase the concentrations of triglycerides in plasma.
