BackgroundHypertension is the leading cause of death in developed countries and reduction of salt intake is recommended as a key preventive measure.ObjectiveTo assess the dietary sodium and potassium intakes in a national sample of Italian children and adolescents and to examine their relationships with BMI and blood pressure (BP) in the framework of the MINISAL survey, a program supported by the Italian Ministry of Health.Population and MethodsThe study population included 1424 healthy subjects (766 boys, 658 girls) aged 6-18 years (mean age: 10.1±2.9) who were consecutively recruited in participating National Health Service centers in 10 Italian regions. Electrolyte intake was estimated from 24 hour urine collections tested for completeness by the concomitant measurement of creatinine content. Anthropometric indices and BP were measured with standardized procedures.ResultsThe average estimated sodium intake was 129 mmol (7.4 g of salt) per day among boys and 117 mmol (6.7 g of salt) among girls. Ninety-three percent of the boys and 89% of the girls had a consumption higher than the recommended age-specific standard dietary target. The estimated average daily potassium intakes were 39 mmol (1.53 g) and 36 mmol (1.40 g), respectively, over 96% of the boys and 98% of the girls having a potassium intake lower than the recommended adequate intake. The mean sodium/potassium ratio was similar among boys and girls (3.5 and 3.4, respectively) and over 3-fold greater than the desirable level. Sodium intake was directly related to age, body mass and BP in the whole population.ConclusionsThe Italian pediatric population is characterized by excessive sodium and deficient potassium intake. These data suggest that future campaigns should focus on children and adolescents as a major target in the framework of a population strategy of cardiovascular prevention.
L. salivarius LS01 seems to be able to improve the quality of life of children affected by AD and, as a consequence, it may have promising clinical and research implications.
Background Iodine is an essential micronutrient for intellectual development in children. Information on iodine intakes based on 24-h urinary iodine excretion (UIE) is scant, because iodine status is only assessed by the measurement of urinary iodine concentration (UIC) in spot urine samples. Objectives The aim of our study was to evaluate the iodine intake of school-age children and adolescents, using UIE measurement in 24-h urine collections. Methods The study population included 1270 healthy subjects (677 boys, 593 girls) aged 6–18 y (mean age ± SD: 10.3 ± 2.9) from 10 Italian regions. Daily iodine intake was estimated as UIE/0.92, based on the notion that $\sim$92% of the dietary iodine intake is absorbed. The adequacy of intakes was assessed according to the Dietary Reference Values for iodine of the European Food Safety Authority (EFSA). Body mass index (BMI) and UIC were also measured for each subject. Results Based on the scientific opinion of EFSA, 600 of 1270 subjects (47.2%) had a lower than adequate iodine intake, with a higher prevalence among girls (54.6%) compared with boys (40.2%) (P < 0.001). Although UIE and 24-h urinary volumes increased with age (P < 0.001), a progressive decrease in the percentage of subjects with iodine excretion <100 µg/24 h (P < 0.001) was observed, without any significant difference in the percentage of subjects with UIC <100 µg/L. No significant association was detected between BMI z-score and UIE (P = 0.603) or UIC (P = 0.869). Conclusions A sizable proportion of our population, especially girls, appeared to be at risk of iodine inadequacy. The simple measurement of UIC could lead to underestimation of the occurrence of iodine deficiency in younger children, because of the age-related smaller urine volumes producing spuriously higher iodine concentrations.
Introduction: The spread of Covid-19 has worsened the prognosis of oncology patients, interrupting or delaying life-saving therapies and contextually increasing the risk of severe SARS-CoV-2 infections. Acute lymphoblastic leukemia (ALL) is the most frequent cancer in pediatric age and the management of this disease with concomitant SARS-COV-2 infection represents a challenging situation.Case presentation: We present the case of a 6-year-old female newly diagnosed with ALL during a documented SARS-CoV-2 infection. Our patient was admitted 20 days after SARS-CoV-2 detection for evening-rise fever. Laboratory testing showed severe neutropenia while chest x-ray detected moderate pulmonary involvement. Acute lymphoblastic leukemia diagnosis was made through morphological and molecular analysis on bone marrow aspirate. Given the stability of the blood count and clinical conditions, antiviral therapy with Remdesivir and Convalescent Plasma was started before antileukemic treatment, obtaining a rapid resolution of the infection.Conclusion: In our experience, the treatment with Remdesivir and Convalescent Plasma led to a rapid resolution of Sars-Cov-2 infection. Our case did not present any adverse event to the therapy. Thus, this treatment could be considered in patients with malignancies, in order to accelerate the resolution of the infection and begin immunosuppressive treatment safely. Further studies are required to confirm this hypothesis.
It is now well established that the CD30 glycoprotein is a surface antigen expressed by activated T cells producing T-helper (Th)-2-type lymphokines. Mounting laboratory evidence, however, suggests that CD30 expression is not confined to a functionally restricted subset of T cells, but also identifies activated cells with a Th-1 and Th-0 pattern of cytokine secretion. CD30-bearing T lymphocytes release a soluble form of the molecule (sCD30), which can be detected both in vitro and in vivo. In the present study, very high levels of sCD30 were found in colostrum from 20 puerperal women, but not in autologous and heterologous (nonpregnant women) blood samples. These data strongly support an involvement of CD30+ T cells in the immune processes which take place at the level of the mammary gland during pregnancy and lactation. Passively transferred immune components such as immunoglobulins, cytokines, macrophages, natural killer cells, granulocytes and memory/activated T cells, all of which may help the baby to fight off infections, have been revealed in human breast milk. However, how Th-2-type cytokine-secreting T cells or other T-cell types help to endow the congenitally immunocompromised newborn infant with extrinsic immunological support remains an open question.
