International journal of molecular sciences. 2023;(6)
Abstract
Sleep-disordered breathing (SDB) comprises different diseases characterized by abnormal respiratory patterns during sleep including obstructive sleep apnea. SDB prevalence and impact in patients with chronic respiratory infections have been only marginally studied. The purpose of this narrative review is to report the prevalence and impact of SDB in chronic respiratory infections, including cystic fibrosis (CF), bronchiectasis and mycobacterial infections, and explore the possible pathophysiological mechanisms. Common pathophysiological mechanisms, underlying SDB onset in all chronic respiratory infections, include inflammation, which plays a central role, chronic nocturnal cough and pain, excessive production of mucous plugs, presence of obstructive and/or restrictive ventilatory impairment, upper airways involvement, and comorbidities, such as alteration of nutritional status. SDB may affect about 50% of patients with bronchiectasis. The severity of the disease, e.g., patients colonized with P. aeruginosa and frequent exacerbators, as well as comorbidities, such as chronic obstructive pulmonary disease and primary ciliary dyskinesia, may impact SDB onset. SDB may also frequently complicate the clinical course of both children and adults with CF, impacting the quality of life and disease prognosis, suggesting that their routine assessment should be incorporated into the clinical evaluation of patients from the first stages of the disease regardless of suggestive symptoms, in order to avoid late diagnosis. Finally, although the prevalence of SDB in patients with mycobacterial infections is uncertain, extrapulmonary manifestations, particularly nasopharyngeal locations, and concomitant symptoms, such as body pain and depression, may act as atypical predisposing factors for their development.

Abstract
The measurement of sodium intake may be important for the management of hypertension. Dietary surveys and 24-h urinary collection are often unreliable and/or impractical. We hypothesized that urinary sodium excretion can be accurately estimated through multiple spot urine samples from different days. All enrolled subjects were children of the coauthors of the study. Fifty-two 24-h urinary collections (4 per subject) for measuring sodium excretion and the 297 related urinary samples (1 per voiding) were collected for calculating the urinary sodium/urinary creatinine ratio in 13 children. The mean of 4 measured sodium excretions served as the individual "gold standard". Twenty-four urinary collections were used to generate the equation predicting the mean measured sodium excretion from the mean of 4 urinary sodium/urinary creatinine [= 0.016 × urinary sodium (mmol/L) / urinary creatinine (mmol/L) ratio + 3.3)]; the remaining 28 urinary collections and 153 urinary samples were used for the external validation. All subjects underwent an additional validation procedure involving 12 urinary samples randomly collected on different days 6 months apart. The performance of sodium excretion calculated from a total of over 22,000 possible means of 4 out of all the available urinary samples, randomly taken on different days, was analyzed as to precision (by means of the coefficient of variation) and as to accuracy (by means of the P30). The coefficients of variations of measured vs. calculated sodium excretion were 25.3% vs. 25.8%, and the P30 of calculated sodium excretion was 100%. The excellent performance of calculated sodium excretion was confirmed both by external validation and by samples collected 6 months apart with mean P30s, all between 86 and 100%.Conclusion: In the described experimental conditions, urinary sodium excretion was estimated with equal precision and more accurately (and practically) by the mean of 4 urinary sodium/urinary creatinine ratios from random samples from different days than by a single urinary collection. In real life, with several errors systematically affecting urinary collection, the superiority of calculated sodium excretion is likely to be even greater. What is Known: • The measurement of sodium intake with the current standards of care (dietary survey or 24-h urinary collection) is laborious and can be inaccurate. What is New: • The study provides evidence that sodium intake can be estimated equally precisely, more accurately and more practically with the urinary sodium-to-urinary creatinine ratio from 4 urine samples taken on different days than with a single urinary collection.

Abstract
Breakfast skipping increases with age, and an association with a high risk of being overweight (OW) and of obesity (OB), cardiometabolic risk, and unhealthy diet regimen has been demonstrated in observational studies with children and adults. Short-term intervention trials in adults reported conflicting results. The purpose of this systematic review was to summarize the association of breakfast skipping with body weight, metabolic features, and nutrition quality in the groups of young people that underwent randomized controlled (RCT) or intervention longitudinal trials lasting more than two months. We searched relevant databases (2000-2021) and identified 584 articles, of which 16 were suitable for inclusion. Overall, 50,066 children and adolescents were included. No studies analyzed cardiometabolic features. Interventions were efficacious in reducing breakfast skipping prevalence when multi-level approaches were used. Two longitudinal studies reported a high prevalence of OW/OB in breakfast skippers, whereas RCTs had negligible effects. Ten studies reported a lower-quality dietary intake in breakfast skippers. This review provides insight into the fact that breakfast skipping is a modifiable marker of the risk of OW/OB and unhealthy nutritional habits in children and adolescents. Further long-term multi-level intervention studies are needed to investigate the relationship between breakfast, nutrition quality, chronotypes, and cardiometabolic risk in youths.

Genoni, G, Conio, A, Binotti, M, Manzoni, P, Castagno, M, Rabbone, I, Monzani, A
American journal of perinatology. 2020;(S 02):S46-S53
Abstract
OBJECTIVE We aimed at reviewing the currently available guidelines and scientific recommendations regarding the neonatal in-hospital management and feeding in the light of the coronavirus disease 2019 (COVID-19) pandemic. STUDY DESIGN We systematically searched the guideline databases, Medline, Embase, and nationale/international neonatal societies websites as of June 19, 2020, for guidelines on neonatal management and feeding during the COVID-19 pandemic, at the same time assessing the methodological quality using the Appraisal of Guidelines for Research and Evaluation II tool. RESULTS Eleven guidelines were included. The Chinese and American recommendations suggest separation of the mother and her neonate, whereas in French, Italian, UK, Canadian, and World Health Organization consensus documents the rooming-in is suggested, with Centers for Disease Control and Prevention guidelines suggesting to decide on a case-by-case basis. All the guidelines recommend breastfeeding or feeding with expressed maternal milk; the only exception is the Chinese recommendations, these last suggesting to avoid breastfeeding. CONCLUSION This review may provide a useful tool for clinicians and organizers, highlighting differences and similarities of the existing guidelines on the management and feeding strategies in the light of the COVID-19 pandemic. KEY POINTS · This study compares guidelines on management and nutrition of a newborn born to a mother with SARS-CoV-2 infection.. · Existing guidelines on neonatal management and nutrition during the SARS-CoV-2 pandemic show many differences.. · The majority of recommendations are mainly based on experts' opinion and are not evidence-based..

Plain language summary
Childhood obesity is a major public health issue across the world. The incidence of skipping breakfast among children and adolescent is rising. Numerous studies have shown a positive relationship between skipping breakfast and overweight or obesity. The aim of the study was to analyse the association of skipping breakfast with body weight and metabolic outcomes in the paediatric population. The study is a systemic review focusing on studies published in the last ten years. 39 articles were included for analysis and data from a total of 286,804 children and adolescents were reported. The systemic review demonstrates that children and adolescents who skip breakfast are at higher risk to be or become overweight or obese. Authors conclude that skipping breakfast may be a potential marker of lifestyle behaviours in children and adolescents that promote overweight or obesity and metabolic diseases.
Abstract
The incidence of skipping breakfast in pediatric subjects is rising, and a relationship with overweight (OW) and obesity (OB) has been shown. Associations with cardiovascular outcomes and skipping breakfast in adults have been reported. The purpose of this systematic review was to summarize the association of skipping breakfast with body weight and metabolic outcomes in the pediatric population. We searched relevant databases (2008⁻2018) and identified 56 articles, of which 39 were suitable to be included, basing on inclusion criteria (observational; defined breakfast skipping; weight and/or metabolic outcomes). Overall, 286,804 children and adolescents living in 33 countries were included. The definitions of OW/OB, skipping breakfast, and the nutrient assessment were highly heterogeneous. Confounding factors were reported infrequently. The prevalence of skipping breakfast ranged 10⁻30%, with an increasing trend in adolescents, mainly in girls. Skipping breakfast was associated with OW/OB in the 94.7% of the subjects. The lack of association was shown mainly in infants. Moreover, 16,130 subjects were investigated for cardiometabolic outcomes. Skipping breakfast was associated with a worse lipid profile, blood pressure levels, insulin-resistance, and metabolic syndrome. Five studies reported a lower quality dietary intake in breakfast skippers. This review supports skipping breakfast as an easy marker of the risk of OW/OB and metabolic diseases, whether or not it is directly involved in causality. We encourage intervention studies using standardized and generalizable indicators. Data on confounders, time of fasting, chronotypes, and nutrition quality are needed to establish the best practice for using it as a tool for assessing obesity risk.

Abstract
BACKGROUND Impairment in orexigenic/anorexigenic hormone balance may be key in the pathogenesis of protein energy wasting in children with chronic kidney disease (CKD). Measurement of ghrelin and obestatin concentrations in children with CKD would help assess the potential contribution of these hormones to uremic protein energy wasting. METHODS This was a cross-sectional case-control study. Acylated and unacylated ghrelin and obestatin were measured in 42 children on conservative treatment (CT), 20 children on hemodialysis, 48 pediatric renal transplant (RTx) recipients and 43 controls (CTR) (mean age 11.9, range 5-20 years). Weight, height and bicipital, tricipital, subscapular and suprailiac folds were measured, and the body mass index-standard deviation score (BMI-SDS), percentage of fat mass and fat-free mass were calculated. Urea and creatinine were measured and the glomerular filtration rate (GFR) calculated. RESULTS Unacylated ghrelin level was higher in patients than controls (p = 0.0001), with the highest levels found in hemodialysis patients (p = 0.001 vs. CKD-CT, p = 0.0001 vs. RTx, p < 0.0001 vs. CTR). Obestatin level was significantly higher in patients on hemodialysis than those on conservative treatment, RTx recipients and controls (p < 0.0001 in each case). Unacylated ghrelin negatively correlated with weight-SDS (p < 0.0001), BMI-SDS (p = 0.0005) and percentage fat mass (p = 0.004) and positively correlated with percentage fat-free mass (p = 0.004). Obestatin concentration negatively correlated with weight-SDS (p = 0.007). Unacylated ghrelin and obestatin concentrations positively correlated with creatinine and urea and inversely with eGFR, even after adjustments for gender, age, puberty and BMI-SDS (p < 0.0001 for each model). CONCLUSIONS Unacylated ghrelin and obestatin, negatively related to renal function, seem to be promising inverse indicators of nutritional status in children with CKD. Potential therapeutic implications in terms of optimization of their removal in patients on hemodialysis could be hypothesized.

Acta paediatrica (Oslo, Norway : 1992). 2017;(10):1589-1595
Abstract
AIM: This study evaluated whether an early aggressive nutrition (EAN) strategy could limit extrauterine growth restriction (EUGR) in a cohort of preterm infants. METHODS This prospective nonrandomised interventional study was carried out in the neonatal intensive care unit of an Italian hospital from January 2013 to December 2015. The prevalence of EUGR was assessed in 100 infants with a gestational age of ≤34 weeks, 50 after the introduction of an EAN regimen in October 2014 and 50 before. RESULTS The prevalence of EUGR at discharge was significantly lower after the introduction of EAN than before for weight (34% vs. 66%), head circumference (22% vs. 42%) and length at discharge (20% vs. 48%). The Z-scores for all measurements were significantly higher after the introduction of EAN. In the EAN group, weight velocity was significantly higher and maximum weight loss and negative changes in the Z-scores from birth to discharge for weight were lower than in the pre-intervention controls. In extremely low birthweight subjects, the weight Z-score and weight velocity were significantly higher in the EAN group than the control group. CONCLUSION The use of EAN at a very early age reduced EUGR and improved auxological outcomes in preterm infants.

Hemolytic uremic syndrome in children.
Talarico, V, Aloe, M, Monzani, A, Miniero, R, Bona, G
Minerva pediatrica. 2016;(6):441-455
Abstract
Hemolytic uremic syndrome (HUS) is a thrombotic microangiopathy defined by thrombocytopenia, non-immune microangiopathic hemolytic anemia and acute renal failure. HUS is typically classified into two primary types: 1) HUS due to infections, often associated with diarrhea (D+HUS, Shiga toxin-producing Escherichia Coli-HUS), with the rare exception of HUS due to a severe disseminated infection caused by Streptococcus; 2) HUS related to complement, such HUS is also known as "atypical HUS" and is not diarrhea associated (D-HUS, aHUS); but recent studies have shown other forms of HUS, that can occur in the course of systemic diseases or physiopathological conditions such as pregnancy, after transplantation or after drug assumption. Moreover, new studies have shown that the complement system is an important factor also in the typical HUS, in which the infection could highlight an underlying dysregulation of complement factors. Clinical signs and symptoms may overlap among the different forms of HUS. Shiga toxin-producing Escherichia Coli (STEC) infection cause a spectrum of clinical sings ranging from asymptomatic carriage to non-bloody diarrhea, hemorrhagic colitis, HUS and death. The average interval between ingestion of STEC and illness manifestation is approximately 3 days, although this can vary between 2 and 12 days. Patients with pneumococcal HUS usually have a severe clinical picture with microangiopathic hemolytic anemia, respiratory distress, neurological involvement. The atypical HUS, in contrast to STEC-HUS which tends to occur as a single event, is a chronic condition and involves a poorer prognosis. Early diagnosis and identification of underlying pathogenic mechanism allow instating specific support measures and therapies. Typical management of STEC-HUS patients relies on supportive care of electrolyte and water imbalance, anemia, hypertension and renal failure. For the aHUS the initial management is supportive and similar to the approach for STEC-HUS; currently we have moved from the historic plasma therapy to new therapeutic approaches, first of all eculizumab, a monoclonal antibody that blocks the C5 cascade. This drug has shown an improvement in platelet count, cessation of hemolysis, improvement of renal function within a few days after the treatment. In patients with end-stage renal disease (ESRD) renal transplantation from a non-related donor and prophylactic administration of eculizumab to prevent recurrent disease in the allograft could be considered.

Prodam, F, Monzani, A, Ricotti, R, Marolda, A, Bellone, S, Aimaretti, G, Roccio, M, Bona, G
The Journal of clinical endocrinology and metabolism. 2014;(5):1556-68
Abstract
OBJECTIVE Food intake and energy balance are regulated during the lifespan with critical changes in each specific period (infancy, adulthood, aging). Some of ghrelin's changes may contribute to the regulation of food intake and weight in children. We aimed to analyze the ghrelin response to feeding in lean or obese subjects from birth to adolescence. METHODS We searched PubMed, Scopus, Google Scholar, Cochrane, and EMBASE (December 1999 to February 2013) and identified 62 relevant articles, of which 29 were suitable to be included. RESULTS AND CONCLUSIONS Total ghrelin response to meals is particular, with refractoriness in neonates and lean children and an inhibition that starts from puberty. Total ghrelin levels are decreased after meals, irrespective of pubertal stages in obese children and adolescents. Conversely, total ghrelin is decreased after an oral glucose tolerance test in all ages, with the exception of neonates. Data on unacylated ghrelin response are scant but resemble those of total ghrelin. The acylated ghrelin response to meals or oral glucose tolerance test is discordant, although a precocious inhibition followed by a rise back is present in both lean and obese children. The post-feeding profile in children with Prader-Willi syndrome is also peculiar, with a conserved and deeper inhibition of all ghrelin forms.

Abstract
AIM: To evaluate if nutritional intakes and lipid profile fulfill international guidelines and recommendations before and after a structured dietician training to a Mediterranean- style diet in an Italian pediatric population with Type 1 diabetes. METHODS A 6-month prospective cohort study. Baseline and after-intervention nutritional intakes, lipid profile, glycated hemoglobin (HbA(1c)), and clinical parameters of 96 children and adolescents with Type 1 diabetes were assessed. A comparative computerized system which was approved and validated by the Italian Diabetologist Association was used to define the amounts of nutrients. RESULTS At baseline mean daily dietary intakes of carbohydrates, proteins, and lipids were respectively (mean ± SEM) 51.8 ± 0.5, 15.9 ± 0.2, 33.8 ± 0.6%, with a contribution of cholesterol of 248.7 ± 12.5 mg/day. Fiber assumption was 18.0 ± 0.4 g/day. The 64.5% and 29.1% (p<0.0001) of subjects had at least one lipid parameter higher than 75(th) and 95(th) percentiles, respectively, of selected cut points (American Diabetes Association guidelines for total and LDL-cholesterol and American Academy of Pediatrics standards for HDL-cholesterol and triglycerides). Six months after the dietician intervention, dietary lipids and cholesterol decreased (p<0.0001) while fibers (p<0.0001) increased. LDL-cholesterol, non-HDL-cholesterol, and total cholesterol:HDL-cholesterol ratios significantly decreased (p<0.001) with a reduction of rate of subjects with at least one pathological lipid parameter (p<0.01) independently by weight and glucose control. CONCLUSIONS Italian pediatric subjects with Type 1 diabetes present a balanced diet with exception of lipids intake and a suboptimal lipid profile. A structured dietician training to a Mediterranean-style diet improves the quality of nutrient intakes being followed by a reduction of LDL-cholesterol, non- HDL-cholesterol, and total cholesterol:HDL-cholesterol ratios.
