Prevalence of anemia among children aged 6-59 months in the Ntele camp for internally displaced persons (Cabo Delgado, Mozambique): a preliminary study.

In July 2022, we conducted a pilot cross-sectional study, within a project funded by the United Nations International Children's Emergency Fund, to investigate the prevalence and predictors of anemia in children aged 6-59 months living in the Ntele camp (Mozambique), created for internally displaced persons (IDPs). We analyzed blood samples for hemoglobin (Hb) and Plasmodium antigens; stool and urine for parasites. Associations between variables were assessed by performing univariate and multivariate logistic regressions. Based on the World Health Organization's Hb cut-offs, we defined anemia (Hb < 110 g/L) as mild (Hb = 100-109 g/L), moderate (Hb = 70-99 g/L), and severe (Hb < 70 g/L). We included 245 children, 212 (83%) were anemic, with 30 (12%) being severely anemic, and 95 (39%) suffered from malaria. Children with moderate-severe anemia were younger than others (mean age = 25.3 and 29.5 months, respectively; p = 0.02). Malaria was positively correlated with moderate to severe anemia (crude OR [95%CI] = 2.5 [1.5-4.5]; sex and age-adjusted OR [95%CI] = 3.1 [1.7-5.6]). Anemia in children under 5 years of age represents an urgent public health threat in the IDPs camp of Ntele, with malaria potentially making them much more susceptible to moderate-severe anemia and other diseases.

Iron Supply of Multivitamins-Multiminerals Commercialized Online by Amazon in Western and Southern Europe: A Labeling Analysis.

Background. In high-income countries, shopping for non-prescription multivitamin-multimineral supplements has tremendously increased. Objective and Methods. The purpose of this labeling analysis is to inform on the daily elemental iron (with or without vitamin C) supply provided by multivitamin-multimineral supplements sold online by Amazon in Western and Southern Europe (amazon.es®, amazon.de®, amazon.it®, and amazon.fr®). Results. We identified 298 iron-containing multivitamin-multimineral preparations sold by Amazon marketplaces: 153 preparations sourced from amazon.de®, 68 from amazon.fr®, 54 from amazon.it®, and 23 from amazon.es®. The daily iron dose provided by these preparations was 14 [5-14] mg (median and interquartile range), with no differences among the marketplaces. Approximately 90% (n = 265) of the preparations contained ferrous iron. Moreover, 85% (n = 253) of the preparations were fortified with vitamin C in a dose of 80 [40-100] mg daily. Conclusions. The median supply of iron (about 14 mg) and vitamin C (80 mg) in iron-containing multivitamin-multimineral preparations offered on Amazon platforms in Western and Southern Europe falls below that currently recommended for iron deficiency in review articles, namely 100 mg of iron and 500 mg of vitamin C per day. The iron supply of iron-containing multivitamin-multimineral preparations falls also below the dose of 30-60 mg advocated to prevent iron deficiency in menstruating women.

Enhancing human milk studies: Introducing a less invasive human milk collection technique for the measurement of fatty acids.

OBJECTIVES: The fatty acid supply of human milk (HM) contributes to health outcomes. Sampling fresh human milk to analyze its fatty acid content is challenging because of its ever-changing nature. Also, obtaining samples from lactating mothers is challenging. Facilitating HM collection and analysis is therefore an advantage. METHODS: We have conducted a study to validate a new method for obtaining HM samples for fatty acid analysis, using biological fluid sample collection pretreated sheets to adsorb drops of milk (Whatman 903 BHT-pretreated biological fluid collection sheet) as an alternative approach to collecting expressed milk. The study population included lactating mothers, enrolled between 24 and 96 h after delivery. RESULTS: A total of 124 breastmilk samples were analyzed using the two distinct approaches. The results of the free milk analysis were comparable to the analysis of adsorbed milk samples. The fatty acid families saturated fatty acids (SFA), monounsaturated fatty acids (MUFA), polyunsaturated fatty acids (PUFA), omega-3, and omega-6 had r2 values of 0.93, 0.91, 0.91, 0.86, and 0.90, respectively. Bland-Altman plots showed a high agreement between fresh and adsorbed milk samples for SFA, MUFA, PUFA, omega-3, and omega-6 with a mean bias <2% and 95% limits of agreement within -5% and +5%. CONCLUSIONS: The results show no significant differences in fatty acid composition between fresh and adsorbed milk samples, suggesting the new method is equally effective in collecting representative samples for analysis.

Ultra-processed foods, allergy outcomes and underlying mechanisms in children: An EAACI task force report.

BACKGROUND: Consumption of ultra-processed foods [UPFs] may be associated with negative health outcomes. Limited data exist regarding the potential role of UPFs in the occurrence of allergic diseases. The underlying mechanisms underpinning any such associations are also poorly elucidated. METHODS: We performed a systematic review and narrative evidence synthesis of the available literature to assess associations between UPF consumption and pediatric allergy outcomes (n = 26 papers), including data on the association seen with the gut microbiome (n = 16 papers) or immune system (n = 3 papers) structure and function following PRISMA guidelines. RESULTS: Dietary exposure to fructose, carbonated soft drinks, and sugar intake was associated with an increased risk of asthma, allergic rhinitis, and food allergies in children. Commercial baby food intake was associated with childhood food allergy. Childhood intake of fructose, fruit juices, sugar-sweetened beverages, high carbohydrate UPFs, monosodium glutamate, UPFs, and advanced glycated end-products (AGEs) was associated with the occurrence of allergic diseases. Exposure to UPFs and common ingredients in UPFs seem to be associated with increased occurrence of allergic diseases such as asthma, wheezing, food allergies, atopic dermatitis, and allergic rhinitis, in many, but not all studies. CONCLUSION: More preclinical and clinical studies are required to better define the link between UPF consumption and the risk of allergies and asthma. These observational studies ideally require supporting data with clearly defined UPF consumption, validated dietary measures, and mechanistic assessments to definitively link UPFs with the risk of allergies and asthma.

The overlapping of phenotypes in Wiedemann-Steiner, Kleefstra and Coffin-Siris syndromes: a study of eleven patients.

BACKGROUND: Some chromatinopathies may present with common clinical findings (intellectual disability, brain and limb malformation, facial dysmorphism). Furthermore, one of their cardinal shared features is growth dysregulation.We aimed to assess and deepen this resemblance in three specific conditions, namely Wiedemann-Steiner (WDSTS), Kleefstra (KLEFS1) and Coffin-Siris syndrome (CSS1), with a particular focus on possible metabolic roots. METHODS: Eleven patients were enrolled, three with WDSTS, five with KLEFS1 and three with CSS1, referring to Fondazione IRCCS Ca' Granda Ospedale Maggiore, Milan, Italy. We performed both a physical examination with detailed anthropometric measurements and an evaluation of the patients' REE (rest energy expenditure) by indirect calorimetry, comparing the results with age- and sex-matched healthy controls. RESULTS: We observed new clinical features and overlap between these conditions suggesting that different disturbances of epigenetic machinery genes can converge on a common effect, leading to overlapping clinical phenotypes.The REE was not distinguishable between the three conditions and healthy controls. CONCLUSIONS: Epigenetic machinery plays an essential role both in growth regulation and in neurodevelopment; we recommend evaluating skeletal [craniovertebral junction abnormalities (CVJ) polydactyly], otolaryngological [obstructive sleep apnea syndrome (OSAs), recurrent otitis media], dental [tooth agenesis, talon cusps], and central nervous system (CNS) [olfactory bulbs and cerebellum anomalies] features. These features could be included in monitoring guidelines. Further studies are needed to deepen the knowledge about energy metabolism.

Ultrasound-detected tenosynovitis in ankles with clinical arthritis and short-term outcome of patients with new-onset juvenile idiopathic arthritis.

OBJECTIVES: To determine features and frequency of ultrasound (US)-detected tenosynovitis in ankles with clinically active disease and to investigate whether its detection may affect the achievement of inactive disease in patients with new-onset juvenile idiopathic arthritis (JIA). METHODS: The study included children with new-onset JIA and clinically active disease of the ankle. Based on US, patients were stratified as having isolated arthritis or as having tenosynovitis irrespective of the presence of concomitant arthritis in the ankle. Estimation of patients who were able to achieve clinically inactive disease 6 months after starting treatment was assessed by the Kaplan-Meier method. Cox model was used to calculate hazard ratio (HR) and 95% confidence interval (CI). Reliability of US was tested using kappa statistic. RESULTS: Forty-five patients were recruited. On US, tenosynovitis of the ankle was detected in 28 patients (62.2%); isolated arthritis was found in 17 patients (37.8%). The medial and lateral tendon compartments were the tendon sites most frequently inflamed. Patients with tenosynovitis had similar likelihood of those without tenosynovitis to achieve clinically inactive disease (60.7% and 58.8%, respectively; HR 1.12, 95%CI:0.51-2.45). In the subanalysis excluding patients who were given biologics, the probability of experiencing inactive disease was slightly higher for patients with tenosynovitis compared to those without (64.7% and 54.5%, respectively; HR 1.56, 95%CI: 0.58-4.24). The rate of US reliability was high. CONCLUSIONS: US-detected tenosynovitis is frequent in ankles with clinical arthritis at JIA onset but does not impair the chance of achieving clinically inactive disease in the early disease phase.

Factors behind Antibiotic Therapy: A Survey of Primary Care Pediatricians in Lombardy.

BACKGROUND: Antimicrobial resistance represents one of the most significant future health challenges in terms of both clinical and economic impacts on healthcare systems. The reason behind this issue is the misuse of antibiotics for the treatment of non-bacterial pathologies. The objective of this study is to investigate the factors underlying antibiotic prescription in pediatricians in the Lombardy region. METHODS: The study was conducted by means of a 32-item questionnaire that investigated both pediatricians' knowledge of antimicrobial resistance and the factors determining the choice to prescribe antibiotic therapy. RESULTS: A total of 253 pediatricians participated in the survey. Most participants (71.6%) reported as highly relevant the need for a national plan against AMR. However, approximately half of the respondents declared the phenomenon of AMR as uncommon in pediatric settings. Among the identified associated factors, diagnostic uncertainty was associated with a stronger fear of legal repercussions and the influence of parental pressure when prescribing antibiotics. CONCLUSIONS: The inability to diagnose the bacterial origin of an infection might be the primary driver of prescribing choices, rather than other non-clinical factors, such as parental demands or a fear of lawsuits.

The Role of Breastfeeding in Acute Respiratory Infections in Infancy.

BACKGROUND: Acute respiratory infections (ARIs) affect the respiratory tract, are often caused by viruses such as respiratory syncytial virus and rhinovirus, and present symptoms such as coughing, fever, respiratory distress, and breathing difficulty. The global adherence to exclusive breastfeeding (BF) for the first 6 months of life has reached 44%, supported by the World Health Organization and United Nations International Children's Emergency Fund efforts. BF provides vital nutrients and contributes to infant immune system development, protecting against infections. The role of BF in preventing and reducing complications of ARIs in infants is gaining attention, prompting a review of current data and future research needs. This review aims to summarize the evidence on the role of BF in reducing the risk and severity of ARIs in infants, elucidate the adaptations in breast milk composition during infections, and identify relevant research needs. METHODS AND RESULTS: Human milk (HM) is rich in immunoglobulins, antimicrobial peptides, and immunomodulatory factors that protect against various pathogens, including respiratory viruses. Several studies have demonstrated that BF is associated with a significant reduction in hospitalization, oxygen requirements, and mortality in infants with ARIs. The effectiveness of BF varies according to the specific respiratory virus, and a longer duration of exclusive BF appears to enhance its protective effect. It is documented that the composition of HM adjusts dynamically in response to infections, fortifying the infant's immune defenses. Specific immunological components of HM, including leukocytes and immunoglobulins, increase in response to infection in the infant, contributing to the enhancement of the immune defense in infants. Immune-boosting microRNAs enhance immune transfer to the infants and promote early gut maturation, and the HM microbiome along with other factors modifies the infant's gut microbiome and immune system. CONCLUSIONS: BF defends infants from respiratory infections, and the investigation of the microRNAs in HM offers new insights into its antiviral properties. The promotion of BF, especially in vulnerable communities, is of paramount importance in alleviating the global burden of ARIs in infancy.

Omega-3 polyunsatured fatty acids and physical performance across the lifespan: a narrative review.

Background and Aims: Physical performance is a major contributor of mobility and independence during older life. Despite a progressive decline in musculoskeletal function starts from middle age, several factors acting during the life-course can negatively influence musculoskeletal functional capacities. Lifestyle interventions incorporating nutrition and physical exercise can help maximizing the muscle functional capacities in early life as well as preserving them later in life. Among various dietary compounds, omega-3 polyunsaturated fatty acids (PUFAs) are gaining growing attention for their potential effects on muscle membrane composition and muscle function. Indeed, several pathways are enhanced, such as an attenuation of pro-inflammatory oxidative stress, mitochondrial function, activation of the mammalian target of rapamycin (mTOR) signaling and reduction of insulin resistance. Methods: We performed a narrative review to explore the existing literature on the relationship between omega-3 PUFAs and physical performance across the life-course. Results: Growing evidence from randomized controlled trials (RCTs) suggests beneficial effects of omega-3 PUFAs on muscle function, including physical performance parameters in mid to later life. On the other hand, despite a direct association in early life is not available in literature, some mechanisms by which omega-3 PUFAs may contribute to improved adult physical performance could be hypothesized. Conclusion: Omega-3 PUFAs are gaining growing attention for their positive effect on muscle function parameters. The integration of physical function measures in future studies would be of great interest to explore whether omega-3 PUFAs could contribute to improved muscle function, starting from early life and extending throughout the lifespan. However, larger and high-quality RCTs are needed to fully elucidate the beneficial effects of omega-3 PUFAs supplementation on muscle mass and function.

Malnutrition management in children with chronic kidney disease.

Chronic kidney disease (CKD) encompasses diverse conditions such as congenital anomalies, glomerulonephritis, and hereditary nephropathies, necessitating individualized nutritional interventions. Early detection is pivotal due to the heightened risk of adverse outcomes, including compromised growth and increased healthcare costs. The nutritional assessment in pediatric CKD employs a comprehensive, multidisciplinary approach, considering disease-specific factors, growth metrics, and dietary habits. The prevalence of malnutrition, as identified through diverse tools and guidelines, underscores the necessity for regular and vigilant monitoring. Nutritional management strategies seek equilibrium in calorie intake, protein requirements, and electrolyte considerations. Maintaining a well-balanced nutritional intake is crucial for preventing systemic complications and preserving the remaining kidney function. The nuanced landscape of enteral nutrition, inclusive of gastrostomy placement, warrants consideration in scenarios requiring prolonged support, with an emphasis on minimizing risks for optimized outcomes. In conclusion, the ongoing challenge of managing nutrition in pediatric CKD necessitates continuous assessment and adaptation. This review underscores the significance of tailored dietary approaches, not only to foster growth and prevent complications but also to enhance the overall quality of life for children grappling with CKD.

What should I eat today? Evidence, guidelines, dietary patterns and consumer's behavior.

Over the past century, dietary recommendations emphasizing food patterns as means to deliver essential nutrients have garnered widespread acceptance. The necessity for foods supplying vital nutrients and energy throughout various life stages requires the involvement of local resources and cultural practices to prevent nutrient deficiency diseases. Since the 1980s, dietary guidelines aimed at adverting chronic diseases have relied on epidemiological research to predict which dietary patterns correlate with reduced risk of chronic disease or links to health outcomes. Dietary guidelines have been broad, typically recommending avoiding excess or deficiency of single nutrients. Efforts to fine-tune these recommendations face challenges due to a scarcity of robust scientific data supporting more specific guidance across the life cycle. Consumers have become skeptical of dietary guidelines, because media coverage of new studies is often in conflict with accepted nutrition dogma. Indications to align individual and planet's health have been issued supporting the concept of sustainable dietary patterns. Whether we really have a science-based databank to support dietary guidelines is still a matter of ongoing debate, as presented in this paper.

A systematic review and meta-analysis of nutritional and dietary interventions in randomized controlled trials for skin symptoms in children with atopic dermatitis and without food allergy: An EAACI task force report.

This systematic review and meta-analysis aimed to consolidate evidence on dietary interventions for atopic eczema/dermatitis (AD) skin symptoms in children without food allergies, following PRISMA 2020 guidelines. Systematic review updates were conducted in May 2022 and June 2023, focusing on randomized placebo-controlled trials (RCTs) involving children with AD but without food allergies. Specific diets or supplements, such as vitamins, minerals, probiotics, prebiotics, symbiotics, or postbiotics, were explored in these trials. Exclusions comprised descriptive studies, systematic reviews, meta-analyses, letters, case reports, studies involving elimination diets, and those reporting on food allergens in children and adolescents. Additionally, studies assessing exacerbation of AD due to food allergy/sensitization and those evaluating elimination diets' effects on AD were excluded. Nutritional supplementation studies were eligible regardless of sensitization profile. Evaluation of their impact on AD clinical expression was performed using SCORAD scores, and a meta-analysis of SCORAD outcomes was conducted using random-effect models (CRD42022328702). The review encompassed 27 RCTs examining prebiotics, Vitamin D, evening primrose oil, and substituting cow's milk formula with partially hydrolyzed whey milk formula. A meta-analysis of 20 RCTs assessing probiotics, alone or combined with prebiotics, revealed a significant reduction in SCORAD scores, suggesting a consistent trend in alleviating AD symptoms in children without food allergies. Nonetheless, evidence for other dietary interventions remains limited, underscoring the necessity for well-designed intervention studies targeting multiple factors to understand etiological interactions and propose reliable manipulation strategies.

The non-clinical burden of febrile seizures: a systematic review.

Febrile seizures (FS) can be frightening for parents, even though they are usually harmless. Various questionnaires have been used to assess parental reactions and awareness about FS, revealing insufficient knowledge. Studies have shown that educational interventions significantly reduce parental concerns, improve knowledge, and promote better first-aid measures. Providing clear information and emotional support to parents is important to reduce their concerns and improve FS management. Healthcare providers should give comprehensive information about FS, including the risk of recurrence, and provide clear instructions on their management. The economic impact of FS includes direct and indirect costs. Studies have shown a decrease of hospitalizations and associated costs due to improved clinical adherence to guidelines, which also reduces the inappropriate use of healthcare resources. This systematic review provides a comprehensive overview of the existing literature on parental anxiety and education about FS, as well as their economic impact, aiming at identifying areas for improvement in the management of FS and providing valuable insights for healthcare providers and policymakers to better address the non-clinical burden of this condition.

Febrile Seizures: A Systematic Review of Different Guidelines.

BACKGROUND: Febrile seizures (FS) are the most common neurological disorder in pediatric age. FS affect 2% to 12% of children and result from a complex interplay of genetic and environmental factors. Effective management and unambiguous recommendations are crucial for allocating health care resources efficiently and ensuring cost-effectiveness in treating FS. METHODS: This systematic review compares existing guidelines to provide insights into FS management. Seven guidelines published between 1991 and 2021, from Japan, United Kingdom, United States, Mexico, India, and Italy, were included. Data extraction covered definitions, diagnostic criteria, hospital admission criteria, diagnostic tests, management, and prophylaxis recommendations. RESULTS: Hospital admission criteria varied but typically included age <18 months and complex FS. Neuroimaging and lumbar puncture recommendations varied, with most guidelines suggesting limited use. Pharmacologic prophylaxis was generally discouraged for simple FS but considered only for high-risk cases, due to the benign nature of FS and the potential side effects of antiseizure medications. CONCLUSIONS: Guidelines on FS exhibit similarities and differences, highlighting the need for standardized management and improved parental education to enhance clinical outcomes and reduce economic and social costs associated with FS. Future research should focus on creating updated international guidelines and ensuring their practical implementation.

Cardiovascular risk and inflammation in a population with autoimmune diseases: a narrative review.

Juvenile Systemic Connective Tissue Diseases (JSCTD) are a heterogeneous group of chronic autoimmune diseases, associated with dyslipidemia and increased cardiovascular risk are related. Studies from the last 10 years, from 2013 to 2022, on lipid profiles in JSCTD were collected. Different studies on lipid profiles in children affected by JSCTD were selected, because the aim is to analyze the cardiovascular risk and the possibility of atherosclerosis in these patients in whom, sometimes, corticosteroid therapies and immunosuppressants increase the state of dyslipidemia. Several studies have shown that autoimmune diseases with an inflammatory substrate also share abnormalities in lipid profile and increased cardiovascular risk. Specifically, associations have been found between Juvenile Systemic Connective Tissue Diseases and elevated triglycerides, TC-C (Total Cholesterol), LDL-C (Low-Density Lipoprotein), low HDL-C (High-Density Lipoprotein), and increased risk of developing diseases such as myocardial infarction, peripheral vascular disease, pulmonary and arterial hypertension, and atrial fibrillation. Supplementation with alpha-linolenic acid (ALA) on the other hand has also been analyzed with positive results in reducing inflammatory parameters, such as IL-6 (Interleukin-6), CRP (C-reactive protein), and fasting glucose, in subjects with dyslipidemia. These observations suggest that supplementation with ALA, an omega-3 precursor, may positively modulate both the inflammatory status and dyslipidemic conditions in patients with autoimmune disorders.

Salivary fatty acids in humans: a comprehensive literature review.

Fatty acids (FAs) exert diverse biological functions in humans, influencing physiological responses and, ultimately, health and disease risk. The analysis of FAs in human samples has significant implications and attracts interest in diagnostics and research. The standard method for assessing FA profiles involves the collection of blood samples, which can be inconvenient, invasive, and potentially painful, particularly for young individuals outside hospital settings. Saliva emerged as a promising alternative for evaluating FA profiles in both clinical and research settings. However, to the best of our knowledge, an updated synthesis of the related evidence is unavailable. This comprehensive review aims to summarize data on FA analysis and highlight the potential of the use of salivary FAs as a biomarker in health and disease. Over the past decade, there has been a growing interest in studying salivary FAs in chronic diseases, and more recently, researchers have explored the prognostic value of FAs in acute conditions to check the availability of a non-invasive sampling methodology. A deeper understanding of salivary FAs could have relevant implications both for healthy individuals and patients, particularly in elucidating the correlation between the dietary lipidic content and salivary FA level, Finally, it is crucial to address the standardization of the methods as the sampling, processing, and analysis of saliva are heterogeneous among studies, and limited correlation between blood FAs and salivary FAs is available.
