RESUMO
OBJECTIVES: Pediatric autoimmune pancreatitis (P-AIP) is an uncommon disease whose diagnosis requires strong clinical suspicion. Late diagnosis increases morbidity. We aimed to compare the usefulness of the 2011 International Consensus Diagnostic Criteria (ICDC) for Autoimmune Pancreatitis with the 2018 INSPPIRE (INternational Study Group of Pediatric Pancreatitis: In search for a cuRE) criteria. METHODS: We retrospectively analyzed demographics and clinical, laboratory, radiological, and histological findings at diagnosis and during long-term follow-up in children diagnosed with AIP in 2 tertiary hospitals between 2008 and 2021. RESULTS: We included 11 patients [6 girls; median age at diagnosis, 12.5 (range 2.8-15.7) years]. The most common symptom was abdominal pain. Pancreatic enzymes were elevated in 10 patients, and serum immunoglobulin G4 was elevated in 1. Magnetic resonance imaging showed enlargement of the pancreatic head in 10 patients and general pancreatic enlargement in 1. Pancreatic and papilla tissue were obtained from 9 patients. All patients received corticosteroids (prednisolone), and 4 also received azathioprine. According to the ICDC, all patients were classified as probable or non-otherwise specified AIP. According to INSPPIRE criteria, all patients were classified as AIP. Using the INSPPIRE criteria would have avoided biopsies in 6 patients who responded well to corticosteroids. CONCLUSIONS: The INSPPIRE criteria are useful. Using the ICDC in pediatric patients can delay diagnosis and result in unnecessary invasive tests.

OBJECTIVE: The high burden associated with respiratory syncytial virus (RSV) has made the development of RSV vaccine(s) a global health high priority. This review summarizes the journey to an RSV vaccine, the different strategies and challenges associated with the development of preventive strategies for RSV, and the diverse products that are undergoing clinical testing. DATA SOURCES: Studies on RSV biology, immunology, epidemiology, and monoclonal antibodies (mAbs) and vaccines were searched using MEDLINE. We also searched PATH.org and ClinicalTrials.gov for updated information regarding the status of RSV vaccines and mAbs undergoing clinical trials. STUDY SELECTIONS: We selected relevant studies conducted in infants and young children, pregnant women, and elderly population for the prevention of RSV infection. RESULTS: Identification of a safe and immunogenic vaccine has been an important but elusive initiative for more than 60 years for different reasons, including the legacy of formalin-inactivated vaccine, our limited understanding of the immune response to RSV and how it relates to clinical disease severity, or the need for different end points according to the different vaccine platforms. Nevertheless, there are currently 39 vaccines and mAbs under development and 19 undergoing clinical trials. CONCLUSION: Over the past decade, there have been significant advances in our knowledge of RSV molecular and structural biology and in understanding the human immune response to RSV. Despite the barriers, there are several promising mAbs and RSV vaccines undergoing clinical trials that hope to offer protection to the most vulnerable populations.

This paper analyzes data from 1666 Spanish industrial firms to test how some human resource (HR) flexibility dimensions mediate the relationship between research and development (R&D) efforts and the absorptive capacity of knowledge (AC). The results show that external R&D experts and core employee training partially mediate the relationship between R&D effort and AC, whereas temporary employment does not mediate that relationship. These findings seem to suggest that HR flexibility dimensions that are more knowledge-intensive are more influential on the development of absorptive capabilities. Another finding is that the mediator effects of HR and AC are positively related to innovation performance, suggesting that firms may combine them more effectively with R&D efforts to enhance innovation.
RESUMO
Seagrasses are globally declining and often their loss is due to synergies among stressors. We investigated the interactive effects of eutrophication and burial on the Mediterranean seagrass, Posidonia oceanica. A field experiment was conducted to estimate whether shoot survival depends on the interactive effects of three levels of intensity of both stressors and to identify early changes in plants (i.e., morphological, physiological and biochemical, and expression of stress-related genes) that may serve to detect signals of imminent shoot density collapse. Sediment burial and nutrient enrichment produced interactive effects on P. oceanica shoot survival, as high nutrient levels had the potential to accelerate the regression of the seagrass exposed to high burial (HB). After 11 weeks, HB in combination with either high or medium nutrient enrichment caused a shoot loss of about 60%. Changes in morphology were poor predictors of the seagrass decline. Likewise, few biochemical variables were associated with P. oceanica survival (the phenolics, ORAC and leaf δ34S). In contrast, the expression of target genes had the highest correlation with plant survival: photosynthetic genes (ATPa, psbD and psbA) were up-regulated in response to high burial, while carbon metabolism genes (CA-chl, PGK and GADPH) were down-regulated. Therefore, die-offs due to high sedimentation rate in eutrophic areas can only be anticipated by altered expression of stress-related genes that may warn the imminent seagrass collapse. Management of local stressors, such as nutrient pollution, may enhance seagrass resilience in the face of the intensification of extreme climate events, such as floods.

Predicting where state-changing thresholds lie can be inherently complex in ecosystems characterized by nonlinear dynamics. Unpacking the mechanisms underlying these transitions can help considerably reduce this unpredictability. We used empirical observations, field and laboratory experiments, and mathematical models to examine how differences in nutrient regimes mediate the capacity of macrophyte communities to sustain sea urchin grazing. In relatively nutrient-rich conditions, macrophyte systems were more resilient to grazing, shifting to barrens beyond 1 800 g m-2 (urchin biomass), more than twice the threshold of nutrient-poor conditions. The mechanisms driving these differences are linked to how nutrients mediate urchin foraging and algal growth: controlled experiments showed that low-nutrient regimes trigger compensatory feeding and reduce plant growth, mechanisms supported by our consumer-resource model. These mechanisms act together to halve macrophyte community resilience. Our study demonstrates that by mediating the underlying drivers, inherent conditions can strongly influence the buffer capacity of nonlinear systems.

RATIONALE: Rhinoviruses (RVs) are a major cause of symptomatic respiratory tract infection in all age groups. However, RVs can frequently be detected in asymptomatic individuals. OBJECTIVES: To evaluate the ability of host transcriptional profiling to differentiate between symptomatic RV infection and incidental detection in children. METHODS: Previously healthy children younger than 2 years old (n = 151) were enrolled at four study sites and classified into four clinical groups: RV- healthy control subjects (n = 37), RV+ asymptomatic subjects (n = 14), RV+ outpatients (n = 30), and RV+ inpatients (n = 70). Host responses were analyzed using whole-blood RNA transcriptional profiles. MEASUREMENTS AND MAIN RESULTS: RV infection induced a robust transcriptional signature, which was validated in three independent cohorts and by quantitative real-time polymerase chain reaction with high prediction accuracy. The immune profile of symptomatic RV infection was characterized by overexpression of innate immunity and underexpression of adaptive immunity genes, whereas negligible changes were observed in asymptomatic RV+ subjects. Unsupervised hierarchical clustering identified two main clusters of subjects. The first included 93% of healthy control subjects and 100% of asymptomatic RV+ subjects, and the second comprised 98% of RV+ inpatients and 88% of RV+ outpatients. Genomic scores of healthy control subjects and asymptomatic RV+ children were similar and significantly lower than those of RV+ inpatients and outpatients (P < 0.0001). CONCLUSIONS: Symptomatic RV infection induced a robust and reproducible transcriptional signature, whereas identification of RV in asymptomatic children was not associated with significant systemic transcriptional immune responses. Transcriptional profiling represents a useful tool to discriminate between active infection and incidental virus detection.

Genetic diversity in clonal organisms includes two distinct components, (i) the diversity of genotypes or clones (i.e. genotypic richness) in a population and (ii) that of the alleles (i.e. allelic and gene diversity within populations, and differentiation between populations). We investigated how population differentiation and genotypic components are associated across a gradient of eutrophication in a clonal marine plant. To that end, we combined direct measurements of sexual allocation (i.e. flower and seed counts) and genotypic analyses, which are used as an estimator of effective sexual reproduction across multiple generations. Genetic differentiation across sites was also modelled according to a hypothesis here defined as isolation-by-demography, in which we use population-specific factors, genotypic richness and eutrophication that are hypothesized to affect the source-sink dynamics and thus influence the genetic differentiation between a pair of populations. Eutrophic populations exhibited lower genotypic richness, in agreement with lower direct measurements of sexual allocation and contemporaneous gene flow. Genetic differentiation, while not explained by distance, was best predicted by genotypic richness and habitat quality. A multiple regression model using these two predictors was considered the best model (R(2) = 0.43). In this study, the relationship between environment and effective sexual-asexual balance is not simply (linearly) predicted by direct measurements of sexual allocation. Our results indicate that population-specific factors and the isolation-by-demography model should be used more often to understand genetic differentiation.

Background: Children and adolescents with chronic pain are a vulnerable population who often lack the resources to manage their condition. Due to high personal, social, and economic consequences, proper management in its early stages is key to reducing disability. The aim of this project is to co-develop a digital intervention for pediatric chronic pain (Digital SPA) with end-users and to evaluate its effectiveness and implementation outcomes in Spain. Methods: (Phase 1) Focus groups with patients, parents, and clinicians (n = 5-6 each) will inform about unmet pain care needs and provide a starting point for co-designing the intervention. (Phase 2) Content creation and usability testing will be based on the results of Phase 1, and the theory-driven development will follow the latest available evidence. The intervention will use validated psychological techniques focused on improving functioning by teaching pain coping skills. (Phase 3) Hybrid effectiveness-implementation trial. Participants (n = 195) will be adolescents aged 12-17 years old with chronic pain and one of their parents. Assessments include physical function, pain, sleep, anxiety, mood, satisfaction and adherence to the treatment, and number of visits to the emergency room. A qualitative framework analysis will be conducted with data from Phase 1. Effects of the intervention will be evaluated using linear multilevel modeling. The Consolidated Framework for Implementation Research (CFIR) and Behavioral Interventions Using Technology (BIT) frameworks will be used to evaluate implementation. Discussion: This study is expected to produce a co-created evidence-based digital intervention for pediatric chronic pain and a roadmap for successful implementation. Trial registration number TRN and date of registration: ClinicalTrials.gov (registered on 26 June 2023: https://clinicaltrials.gov/study/NCT05917626). Contributions to the literature The implementation of digital health interventions has two major gaps: (1) adherence to treatment is suboptimal, and (2) the process of making the interventions available to the end-user in a sustainable way is often unsuccessful.In this study, we expect that assessing users' needs and co-designing an intervention with them will improve adherence.Documenting the implementation process from the project inception and integrating the results into an implementation framework will allow for replication and extension in different contexts.This study will increase the knowledge about implementation in a vulnerable population: adolescents with chronic pain without access to in-person multidisciplinary pain care.
RESUMO
Respiratory syncytial virus (RSV) is associated with major morbidity in infants, although most cases result in mild disease. The pathogenesis of the disease is incompletely understood, especially the determining factors of disease severity. A better characterization of these factors may help with development of RSV vaccines and antivirals. Hence, identification of a "safe and protective" immunoprofile induced by natural RSV infection could be used as a as a surrogate of ideal vaccine-elicited responses in future clinical trials. In this study, we integrated blood transcriptional and cell immune profiling, RSV loads, and clinical data to identify factors associated with a mild disease phenotype in a cohort of 190 children <2 years of age. Children with mild disease (outpatients) showed higher RSV loads, greater induction of interferon (IFN) and plasma cell genes, and decreased expression of inflammation and neutrophil genes versus children with severe disease (inpatients). Additionally, only infants with severe disease had increased numbers of HLA-DRlow monocytes, not present in outpatients. Multivariable analyses confirmed that IFN overexpression was associated with decreased odds of hospitalization, whereas increased numbers of HLA-DRlow monocytes were associated with increased risk of hospitalization. These findings suggest that robust innate immune responses are associated with mild RSV infection in infants.

Sea urchins may deeply shape the structure of macrophyte-dominated communities and require the implementation of sustainable management strategies. In the Mediterranean, the identification of the major recruitment determinants of the keystone sea urchin species Paracentrotus lividus is required, so that source areas of the populations can be identified and exploitation or programmed harvesting can be spatially managed. In this study a collection of eight possible determinants, these encompassing both the biotic (larvae, adult sea urchins, fish, encrusting coralline algae, habitat type and spatial arrangement of habitats) and abiotic (substrate complexity and nutritional status) realms was considered at different spatial scales (site, area, transect and quadrat). Data from a survey including sites subject to different levels of human influence (i.e. from urbanized to protected areas), but all corresponding to an oligotrophic and low-populated region were fitted by means of a generalized linear mixed model. Despite the extensive sampling effort of benthic quadrats, an overall paucity of recruits was found, recruits being aggregated in a very small number of quadrats and in few areas. The analysis of data detected substrate complexity, and adult sea urchin and predatory fish abundances as the momentous determinants of Paracentrotus lividus recruitment. Possible mechanisms of influence are discussed beyond the implications of conservation management.

Habitat structure plays an important mediating role in predator-prey interactions. However the effects are strongly dependent on regional predator pools, which can drive predation risk in habitats with very similar structure in opposite directions. In the Mediterranean Sea predation on juvenile sea urchins is commonly known to be regulated by seagrass structure. In this study we test whether the possibility for juvenile Paracentrotus lividus to be predated changes in relation to the fragmentation of the seagrass Posidonia oceanica (four habitat classes: continuous, low-fragmentation, high-fragmentation and rocks), and to the spatial arrangement of such habitat classes at a landscape scale. Sea urchin predation risk was measured in a 20-day field experiment on tethered individuals placed in three square areas 35×35 m2 in size. Variability of both landscape and habitat structural attributes was assessed at the sampling grain 5×5 m2. Predation risk changed among landscapes, as it was lower where more 'rocks', and thus less seagrass, were present. The higher risk was found in the 'continuous' P. oceanica rather than in the low-fragmentation, high-fragmentation and rock habitats (p-values = 0.0149, 0.00008, and 0.0001, respectively). Therefore, the expectation that juvenile P. lividus survival would have been higher in the 'continuous' seagrass habitat, which would have served as shelter from high fish predation pressure, was not met. Predation risk changed across habitats due to different success between attack types: benthic attacks (mostly from whelks) were overall much more effective than those due to fish activity, the former type being associated with the 'continuous' seagrass habitat. Fish predation on juvenile sea urchins on rocks and 'high-fragmentation' habitat was less likely than benthic predation in the 'continuous' seagrass, with the low seagrass patch complexity increasing benthic activity. Future research should be aimed at investigating, derived from the complex indirect interactions among species, how top-down control in marine reserves can modify seagrass habitat effects.

Very rare cases of hypersensitivity reactions to various constituents of parenteral nutrition (PN) have been reported in children. Adverse effects associated with PN administration have centered on metabolic, infectious, and mechanical complications. Here we describe three cases of hypersensitivity to components of PN. Case 1 is a 1-mo-old breastfed baby with a diagnosis of acute gastroenteritis associated with an infection with cytomegalovirus. On the second day of PN, 60 min after the initiation of the infusion, the patient had an allergic reaction with an overall diffused rash. On day 4 of PN, the multivitamin solution and the trace element mix were excluded, showing a good tolerance. Case 2 is a 4-y-old girl with a background of stage III neuroblastoma. On day 3 of PN, 15 min after the initiation of the infusion, the patient showed sudden facial edema. On day 5, suspecting the amino acid solution to be the etiology of her reaction, PN was infused with another amino acid preparation, and the patient showed good tolerance. Case 3 is a 10-y-old boy with a diagnosis of an acute peritonitis. Two h after the initiation of the infusion, the patient showed a general wheal rash. He referred a background of fish allergy. Considering that the lipid emulsion used had components from fish oil (SMOF Lipid), a new PN was infused on day 2. The new PN contained a lipid emulsion containing vegetable oil (ClinOleic). The patient showed good tolerance. In conclusion, we consider that, although the hypersensitivity to PN components is infrequent, there is an increase in reports of pediatric cases describing this allergic pathology.
