Abstract
Abstract
Background
Noncommunicable diseases (NCDs) share key determinants like unhealthy diet, unhealthy 24h- movement behaviour (sleep, sedentary behaviour and physical activity), leading to other risks including overweight, obesity and raised blood pressure. Although the manifest of the NCDs in childhood is rare, risk behaviours, obesity, and raised blood pressure that accelerates their development begin during childhood. The current study aims to analyze the effectiveness of the intervention program based on the promotion of health literacy and lifestyles, on children’s health literacy, lifestyles (e.g. dietary intake, 24hmovement behaviour) and overweight and obesity.
Methods
478 children (6 schools) aged 6-12years old will participate in this cluster-randomized trial, having schools as the unit of randomization, assigned into intervention (239-3schools) and the control arm (239-3schools). This project is currently performing social listening (online and offline) and stakeholders’ involvement. Data collection includes sociodemographics, health literacy and infodemic resilience, dietary intake and children’s 24-h movement behaviour (e.g. accelerometry), anthropometry (e.g. weight, height and waist circumference) and blood pressure. It will occur at baseline and after the intervention (follow-up, 6 months after the beginning of the intervention).
Results
Expected outputs and outcomes include the 1-creation of a model for characterizing NCDs and health topics based on artificial intelligence techniques (e.g. deep learning, social network analysis methods).2- improved health literacy and infodemic resilience of children, families and teachers.3- enhanced children’s lifestyles. 4- reduce NCDs’ physical risk factors (e.g. overweight, raised blood pressure).
Conclusions
A feasible intervention program for school-aged children with vulnerabilities enhances tailored policies about health promotion and NCDs’ prevention, respecting the contextś singularities.
Key messages
• Health promotion and NCDs prevention are crucial for the well-being of our societies.
• Feasible intervention programs advocates for evidence-based policies that respect local singularities.

Abstract
BACKGROUND In Europe, pediatric transplantation accounts for only about 4% of all kidney transplantations performed. The aim of our work is to evaluate the evolution of pediatric renal transplantation in our department over time, but also to compare this special population with the adult one. METHODS We evaluated all pediatric renal transplantations performed in our department between January 1981 and December 2016. We performed the analysis of clinical, analytical, and surgical factors to look for predictive factors of graft loss or decrease of survival. In addition, we performed a comparative study of pediatric and adult populations and an evaluation of the evolution of pediatric renal transplantation in our department over time. RESULTS We evaluated 101 renal transplantations performed in patients younger than 18 years. Pediatric transplantations corresponded to 3.4% of all renal transplantations performed in our department. The rate of living donors was 12%. Donors of grafts for the pediatric population were significantly younger than in the adult population. The increase in donor age was associated with lower renal graft survival rates. Acute rejections were more frequent in the pediatric population. Eleven pediatric recipients (10.9%) died in the follow-up period. Renal graft survival in the pediatric population was 94.8%, 77.4%, and 66.5% at 1, 5, and 10 years, respectively. There was no significant difference in graft survival in the pediatric and adult population. The pediatric overall survival rate at 1, 5 and 10 years was 97.9%, 96.8%, and 91.9%, respectively. CONCLUSION Pediatric renal transplantation presents results identical to those identified in adults.

Abstract
OBJECTIVE To compare secondhand smoke exposure (SHSe) prevalence at home and inside the car between asthmatic and non-asthmatic Portuguese children. MATERIALS AND METHODS This is a cross-sectional study that assessed children's SHSe in a representative sample of nine Portuguese cities. A validated self-reported questionnaire was administered to a random sample of 4th grade students during the school year of 2010/2011. The asthma prevalence was defined by the answers to three questions regarding asthma symptoms, medication and inhaler use. We performed chi-square tests and analysed frequencies, contingency tables, confidence intervals, and odd-ratios. RESULTS The self-reported questionnaire was administered to 3187 students. Asthma prevalence was 14.8% (472 students). Results showed that 32.3% of non-asthmatic children and 32.4% of asthmatic children were exposed to secondhand smoke as at least one of their household members smoked at home. The prevalence of parental smoking, smoking among fathers and smoking among mothers at home was also similar in both groups (asthmatic and non-asthmatic children). SHSe inside the car was 18.6% among non-asthmatic children and 17.9% among asthmatic children. CONCLUSIONS Asthmatic and non-asthmatic children were equally exposed to secondhand smoke, because no significant differences were found between the two groups concerning the prevalence of SHSe at home and inside the car. These findings highlight the need to include SHSe brief advice in paediatric asthma management.

Abstract
INTRODUCTION According to the MPOWER approach adopted in 2008 by the WHO, monitoring smoking epidemics is necessary in order to assess the effectiveness of the preventive measures used in smoking control in adolescents and adults. OBJECTIVES To determine the prevalence of smoking in Portuguese school-aged adolescents by region. MATERIAL AND METHODS The sample is made up of 8764 students, 4060 boys and 4704 girls, and is representative of the Portuguese students in regular public education. The data was collected in the 2008/2009 academic year, through a quantitative self-report questionnaire. RESULTS In the total sample, 10.2% of boys and 9.1% of girls are regular smokers. Smoking increases with age. At 15 years old 12.3% of the boys and 8.6% of the girls are regular smokers and 6.1% of the boys and 4.0% of the girls are occasional smokers. Looking at prevalence by region, the highest prevalence of regular smoking is found in Alentejo (14.7%), followed by Azores (11.8%) and the lowest is found in Algarve (4.1%). CONCLUSIONS The prevalence of smokers among Portuguese school-aged adolescents varies within the several regions of the country, similar to what happens in the adult Portuguese population.

Abstract
Background In 2006, bronchiolitis due to adenovirus nosocomial infections resulted in the closure of a pediatric department in northern Portugal. Objectives To determine the etiology of bronchiolitis in northern Portugal. Study design It was a prospective multicenter study on the etiology of bronchiolitis during the respiratory syncytial virus (RSV) season (November–April). Children ≤24 months of age admitted for a first wheezing episode were included. Nasopharyngeal specimens were analyzed by an indirect immunofluorescent-antibody assay (IFA) for RSV, adenovirus (HAdV), parainfluenza (PIV) 1–3 and influenza (IV) A and B and by polymerase chain reaction (PCR) or reverse transcription-PCR for the same viruses and for human metapneumovirus (hMPV), bocavirus (HBoV), rhinovirus (HRV), coronaviruses (229/E; NL63; OC43; HKU1) and enterovirus. Results During this period, 253 children were included, 249 IFA analyses and 207 PCRs were performed. IFA detected RSV in 58.1%; PCR increased it to 66.7%. IFA detected HAdV in 3.2%, PCR 10.0%. PCR detected IV A in 5; IV B in 2; PIV 1 in 6, PIV 2 in 4 and PIV 3 in 11 cases. HBoV, as single agent in 2 cases, and HRV were positive in 8 samples and hMPV in 11. With this virus panel, 19.7% remained without etiology. Conclusions The most frequent agent was RSV, followed by HAdV. PCR can be cost-effective and more accurate than IFA, which is crucial for HAdV that may be associated with significant mortality (IFA alone did not detect 2/3 of the cases).

A 14-year-old previously healthy girl had unexplained pain in the left leg, as well as psychiatric disturbances. This was shortly followed by progressive cognitive impairment, ataxia and generalised choreoatethosis. Neuropsychological assessment revealed severe frontal and medial temporal dysfunction, the posterior cortices being spared. An electroencephalogram was normal. CSF 14.3.3 protein was slightly positive. Magnetic resonance imaging showed the "hockey stick sign" and hyperintensities in the periaquedutal grey matter and in the right parietal cortex, the last with restriction to water molecule movement. SPECT revealed perfusion defects in the left frontotemporal and right parietal regions. PRNP gene sequencing showed no mutations, the patient being homozygous to methionine in codon 129. Five months after onset, immunocytochemical and immunoblotting analysis confirmed deposition of prion protein and a PrP4t electrophoretic pattern. The patient never travelled outside Portugal or received blood transfusions. She had surgical herniorrhaphy in 1998 (when catgut was used) and 2003. This is the second case in Portugal in a 2-year period and 20 km apart from each other, with no known common exposure apart from ingestion of cow meat. We discuss these case peculiarities and underline its epidemiological significance.

Abstract
Developing B cells must pass a series of checkpoints that are regulated by membrane-bound Ig(mu) through the Igalpha-Igbeta signal transducers. To determine how Ig(mu) expression affects B cell development and Ab selection in humans we analyzed Ig gene rearrangements in pro-B cells from two patients who are unable to produce Ig(mu) proteins. We find that Ig(mu) expression does not affect V(H), D, or J(H) segment usage and is not required for human Igkappa and Iglambda recombination or expression. However, the heavy and light chains found in pro-B cells differed from those in peripheral B cells in that they showed unusually long CDR3s. In addition, the Igkappa repertoire in Ig(mu)-deficient pro-B cells was skewed to downstream Jkappas and upstream Vkappas, consistent with persistent secondary V(D)J rearrangements. Thus, Ig(mu) expression is not required for secondary V(D)J recombination in pro-B cells. However, B cell receptor expression shapes the Ab repertoire in humans and is essential for selection against Ab's with long CDR3s.

Abstract
AIM To find the prevalence of antibody to hepatitis A virus in the population of the North of Portugal. MATERIAL AND METHODS Ten General Practitioners were asked to provide blood samples from patients who would need blood tests for any reason other than acute hepatitis, during January and February 1996. In this way, 381 samples were obtained for assessment of anti hepatitis A virus antibodies using a commercial radioimmunassay ELISA. All subjects gave their informed consent and answered to a protocol regarding age, sex, geographic area, number of people per household and sewage systems. The statistics were performed using SPSS. RESULTS The 381 subjects were distributed into eight age groups: I (1-4 years)--57; II (5-9 years)--57; III (10-14 years)--26; IV (15-19 years)--41; V (20-29 years)--55; VI (30-39 years)--51; VII (40-49 years)--41; VIII--(equal or more than 50 years)--53. The prevalence of anti HAV antibodies per group-percentage (number), (confidence intervals), were: I--7.0% (4) (3-17%); II--15.8% (9), (9-27%); III--26.9% (7) (14-46%); IV--51.2% (21) (37-66%); V--85.5% (47) (74-92%); VI--72.5% (37) (59-83%); VII--87.8% (36) (75-95%); VIII--88.7% (47) (80-93%). CONCLUSION The comparison with previous data (Lecour et al.) shows improvement in sanitary conditions of population, with associated lower prevalence of anti hepatitis A virus antibody.

Abstract
BACKGROUND Posttransplant lymphoproliferative disease (PTLD) is a life-threatening condition the incidence of which in pediatric solid organ transplantation may be related to the immunosuppressive load. It has been suggested that tacrolimus, a new and potent immunosuppressor, causes an increased incidence of this syndrome. METHODS The incidence, early signs, and risk factors for lymphoproliferative disease were reviewed in a cohort of 89 pediatric liver transplant recipients treated with tacrolimus. RESULTS Eighteen patients (20%) developed a PTLD-16 concomitant to a primary Epstein-Barr virus (EBV) infection and 2 with previous immunity against EBV. Three additional patients had preliminary signs of PTLD concomitant to primary EBV infection, but did not develop individualized lymphoid masses. Six patients died (6.7% of all tacrolimus-treated patients). Mean tacrolimus blood level during the 3 months preceding EBV infection reached 11.8+/-1.8 ng/ml in PTLD patients versus 9.4+/-3.4 ng/ml in non-PTLD patients (0.05<P<0.1). Previous OKT3 or antithymocyte globulin treatment was also significantly associated to PTLD. There was no association with age, rejection episodes, steroid-resistant rejection, prior cytomegalovirus infection, HLA mismatch, living donor or cadaveric organ transplantation, United Network for Organ Sharing status at the time of orthotopic liver transplant, and primary or rescue tacrolimus treatment. A significant increase of total gamma-globulin level occurred in PTLD patients, and mono/oligoclonal production was significantly associated to PTLD. CONCLUSION In EBV-infected pediatric liver transplant recipients, use of OKT3 or antithymocyte globulin and high tacrolimus blood levels are risk factors for a significant increase in the incidence of PTLD. An increase in total gamma-globulin level and appearance of mono/oligoclonal immunoglobulin production are the major preliminary signs of the syndrome.
