A two-week summer program promoting physical activity: quality of life assessment in Italian children.

Physical activity (PA) can be associated with better health-related quality of life (HRQoL). This study aimed to assess HRQoL before and after a two-week summer program promoting PA in Italian school-aged children. Participants were recruited during the Giocampus summer2017 (Parma, Italy), from June to July. Before (T0) and after (T1) the program, children and one of their parents answered the Kindl questionnaire. For each domain, least-square mean changes (LSmc) at T1 were derived from linear regression models stratified by responder and adjusted for child gender, age group, time spent in PAs and HRQoL score of the responder at T0. 350 children (7-13 years, 52% males) and 342 parents answered the questionnaire at both T0 and T1. At T1, the HRQoL score of the children significantly improved in the emotional (LSmc 2.9, p<0.001), self-esteem (LSmc 3.3, p<0.001), family (LSmc 4.2, p<0.001) and friend (LSmc 3.1, p<0.001) domains. Parents reported significantly more improvement in self-esteem than children (LSmc 6.7 vs 3.3, p=0.012). Children spending more time in PA reported significantly more improvement in self-esteem than those doing less PA (LSmc 4.4 [p<0.001] vs 2.2 [p=0.181]). A short summer program promoting PA may improve HRQoL in the general population of school-aged children.

Giocampus school: a "learning through playing" approach to deliver nutritional education to children.

To improve nutritional knowledge of children, single-group educational interventions with pre/post knowledge assessment were performed in primary schools in Parma, Italy, participating to the Giocampus Program. A total of 8165 children (8-11 years old) of 3rd, 4th and 5th grades of primary school were involved in 3 hours per class nutritional lessons, with specifically designed games and activities for each school grade. To evaluate children learning, a questionnaire was administered before and after three months of educational intervention. A total of 16330 questionnaires were analysed. Children nutritional knowledge significantly increased (p< 0.001) in all school grades. The integrated "learning through playing" approach, including the educational figures, tools and games, was successful in improving children's nutritional knowledge. A stable integration of this method in primary school settings could prepare a new generation of citizens, better educated on health-promotion lifestyles.

Metabolic outcomes in young children with type 1 diabetes differ between treatment centers: the Hvidoere Study in Young Children 2009.

OBJECTIVE: To investigate whether center differences in glycemic control are present in prepubertal children <11 yr with type 1 diabetes mellitus. RESEARCH DESIGN AND METHODS: This cross-sectional study involved 18 pediatric centers worldwide. All children, <11 y with a diabetes duration ≥12 months were invited to participate. Case Record Forms included information on clinical characteristics, insulin regimens, diabetic ketoacidosis (DKA), severe hypoglycemia, language difficulties, and comorbidities. Hemoglobin A1c (HbA1c) was measured centrally by liquid chromatography (DCCT aligned, range: 4.4-6.3%; IFFC: 25-45 mmol/mol). RESULTS: A total of 1133 children participated (mean age: 8.0 ± 2.1 y; females: 47.5%, mean diabetes duration: 3.8 ± 2.1 y). HbA1c (overall mean: 8.0 ± 1.0%; range: 7.3-8.9%) and severe hypoglycemia frequency (mean 21.7 events per 100 patient-years), but not DKA, differed significantly between centers (p < 0.001 resp. p = 0.179). Language difficulties showed a negative relationship with HbA1c (8.3 ± 1.2% vs. 8.0 ± 1.0%; p = 0.036). Frequency of blood glucose monitoring demonstrated a significant but weak association with HbA1c (r = -0.17; p < 0.0001). Although significant different HbA1c levels were obtained with diverse insulin regimens (range: 7.3-8.5%; p < 0.001), center differences remained after adjusting for insulin regimen (p < 0.001). Differences between insulin regimens were no longer significant after adjusting for center effect (p = 0.199). CONCLUSIONS: Center differences in metabolic outcomes are present in children <11 yr, irrespective of diabetes duration, age, or gender. The incidence of severe hypoglycemia is lower than in adolescents despite achieving better glycemic control. Insulin regimens show a significant relationship with HbA1c but do not explain center differences. Each center's effectiveness in using specific treatment strategies remains the key factor for outcome.

Children with type 1-diabetes from ethnic minorities: vulnerable patients needing a tailored medical support.

BACKGROUND AND AIM: Newly diagnosed children with type 1 diabetes from ethnic minorities are a growing presence in outpatient pediatric clinics, and are reported as a group at risk of poor metabolic control. In the present study we investigated the barriers affecting chances of minority diabetic children to achieve the same metabolic targets of native peers with type 1 diabetes. MATERIALS AND METHODS: The study investigated 35 children from ethnic minorities (group 1) admitted to the Children University Hospital of Parma, Italy, from 1st January 2000 to December 31st, 2011, and data concerning current age, gender, ethnicity, age at diabetes onset, HbA1c, DKA severity degree at diagnosis, insulin therapy, annual number of out patient clinic visits, number of admissions for acute decompensation, and treatment cost. A short questionnaire on background, family situation, difficulties in diabetes monitoring, and outpatient clinic procedures completed the study. The results were compared with data collected from 30 matched native peers (group 2). RESULTS: Mean HbA1c level at admittance was higher in Group 1 (11.8 +/- 1.0%) than in Group 2 (9.0 +/- 2.2%; p=0.000). The differences were confirmed when HbAlc mean cumulative values (8.6 +/- 2.1 vs 7.6 +/- 1.1; p=0.022) were calculated. Group 1 children at admission showed poorer metabolic conditions and longer stay at hospital (16 +/- 3 days) than Group 2 patients (8 +/- 2 days; p=0.000). The total costs for DKA treatment and family education resulted higher in group 1 (+54%) than in group 2 patients. Discontinuous capillary blood glucose monitoring and outpatient clinic visits missed were more frequent in Group 1 than in group 2 patients. Thirteen patients in group 1 needed a re-admittance to hospital because of a hypoglycemia (5 cases) or a hyperglycemia (8 cases). The same episodes were not recorded in group 2 patients. Most of parents expressed the wish to be supported with educational material in their own language. CONCLUSIONS: Children with TDM belonging to an ethnic minority had poorer metabolic control compared with native patients. This results from several cultural, educational, economic deficiencies which influence their family life and probably reduced their chances to obtain a better control.

Sulfonylurea-responsive neonatal diabetes mellitus diagnosed through molecular genetics in two children and in one adult after a long period of insulin treatment.

A permanent neonatal diabetes mellitus has finally been diagnosed through molecular genetics in two children and one adult after 9 to 35 years of uninterrupted insulin treatment. These patients developed diabetes before 6 months of age and were autoantibody negative. In one boy, a mutation in the KCNJ11 gene was identified at 9 years of age. In the other two patients (daughter and father, 12.6 and 25 years old respectively) the new gene variant (ABCC8/L213P) was found. Switching from insulin to sulfonylurea treatment leads to the definitive discontinuance of insulin therapy, improving metabolic control as well as the amelioration of the associated neurodevelopmental disabilities in the young girl in which an intermediate Development Delay, Epilepsy, Neonatal Diabetes syndrome was diagnosed.

The PTPN22 C1858T gene variant is associated with proinsulin in new-onset type 1 diabetes.

BACKGROUND: The protein tyrosine phosphatase nonreceptor type 2 (PTPN22) has been established as a type 1 diabetes susceptibility gene. A recent study found the C1858T variant of this gene to be associated with lower residual fasting C-peptide levels and poorer glycemic control in patients with type 1 diabetes. We investigated the association of the C1858T variant with residual beta-cell function (as assessed by stimulated C-peptide, proinsulin and insulin dose-adjusted HbA1c), glycemic control, daily insulin requirements, diabetic ketoacidosis (DKA) and diabetes-related autoantibodies (IA-2A, GADA, ICA, ZnT8Ab) in children during the first year after diagnosis of type 1 diabetes. METHODS: The C1858T variant was genotyped in an international cohort of children (n = 257 patients) with newly diagnosed type 1 diabetes during 12 months after onset. We investigated the association of this variant with liquid-meal stimulated beta-cell function (proinsulin and C-peptide) and antibody status 1, 6 and 12 months after onset. In addition HbA1c and daily insulin requirements were determined 1, 3, 6, 9 and 12 months after diagnosis. DKA was defined at disease onset. RESULTS: A repeated measurement model of all time points showed the stimulated proinsulin level is significantly higher (22%, p = 0.03) for the T allele carriers the first year after onset. We also found a significant positive association between proinsulin and IA levels (est.: 1.12, p = 0.002), which did not influence the association between PTPN22 and proinsulin (est.: 1.28, p = 0.03). CONCLUSIONS: The T allele of the C1858T variant is positively associated with proinsulin levels during the first 12 months in newly diagnosed type 1 diabetes children.

Differences between ethnic minority and native children in breakfast habits.

Aim of this study was to investigate the breakfast habits in a cohort of school ethnic minority (EM) children admitted to a summer sport school (SSS) in order to evaluate the possible differences with their Italian peers (IP). One hundred-seventy-nine children aged 6-14 years were interviewed through a questionnaire about breakfast behaviors and nutrition habits. The results were compared with those obtained in a randomized sample of 179 Italian peers (IP) attending the same SSS. EM children skip breakfast more frequently than IP (15% vs 7%; p = 0.029). The omissions are attributed to the lack of time (45% vs 54%) and not being hungry upon waking (44% vs 38%). During weekends the percentage of breakfast skippers decreased of about 3 percentage points but persisted a significant difference between the two groups (p = 0.024). EM children who did not have breakfast show a mean BMI higher than breakfast consumers (p = 0.05). Bakery products and milk were the most frequently consumed food and drink in EM and IP children (68% vs 70% and 71% vs 76% respectively). EM children chose and prepared personally breakfast at home more frequently than IP (54% vs 22%). These EM children were more inclined to skip breakfast (p = 0.025) and to have an elevated BMI (p = 0.006) than IP. An educational program, for ethnic minority families, in different languages and according to their cultural, religious and socio-economic influences could be a possible means for changing their lifestyle and reducing their risk to become overweight.

Physical activity and sedentary lifestyle in children with type 1 diabetes: a multicentre Italian study.

BACKGROUND: Regular Physical Activity (RPA) is one of the cornerstones of Type 1 Diabetes (T1D) therapy, but conflicting results are reported in the literature. AIM: To compare (RPA) and Sedentary Lifestyle (SL) among children with type 1 diabetes (T1D) and healthy peers. SUBJECTS AND METHODS: Seven Italian paediatric diabetes centres enrolled 129 children with T1D and 214 healthy peers who were interviewed by a telephone questionnaire on physical activity level, sedentary lifestyle and clinical data. RESULTS: Compared to healthy peers, children with T1D: performed the same amount of RPA, were more frequently engaged in team sports (p = 0.018), described RPA as an enjoyable activity (p = 0.033), not boring (p = 0.035), a chance to spend time with peers (p = 0.033) and to meet new friends (p = 0.016). Children with T1D were finally used to consume less snacks during watching TV (p < 0.001) or after physical activity (p < 0.001 ). HbA1c values were not related with time spent in physical activity, in watching TV or in playing video-games. CONCLUSIONS: Most interviewed children with T1D are physically active and perform the same amount of exercise as their healthy peers. They demonstrate to consider RPA a source of enjoyment and sociality and not a therapeutic imposition. (www.actabiomedica.it)

Tips to avoid weak scientific English.

In the present issue of Acta Biomedica is published a contribution of Rago V on "Scientific writing like a native English-speaker: tips for Italian researchers". The Author, over the past years, has collaborated with Italian researchers and has generally noticed that their English  status is relatively weak. Therefore, he gives "tips or dritte that do not always refer to incorrect English, but rather to weak scientific English" (1). [...].

Celiac disease in children with type 1 diabetes: impact of gluten free diet on diabetes management.

UNLABELLED: Background and aim of the work the coexistence of Type 1 Diabetes (T1D) and celiac disease (CD) has been long established. METHODS: Between January 2000 and December 2009, biopsy-proven CD was diagnosed in 12 children with T1D, giving a prevalence of 4.8 % in our out-patient clinic population. For each patient with coexisting T1D and CD, two control subjects with T1D and without CD who matched for age, sex and duration of diabetes were chosen. Prospective study follow up lasted 24 months. At the enrolment time, and at 2-month intervals, time from diagnosis of T1D to diagnosis of CD, presence of gastrointestinal symptoms, HbA1c value, body mass index (BMI), Height and Weight SDS were collected by a single observer. Daily insulin requirements were also retained. RESULTS: In 3 children, CD predated the onset of T1D and these children were excluded from the analysis. The 9 children who subsequently developed CD became earlier diabetic than control group (p=0.002). Eight of these children had CD diagnosis within 1 year after T1D onset. Seven out of 9 children were positive for TTG antibodies and all were positive for EMA. A significant increase in insulin requirement was found in CD children after 1 year of GFD (p= 0.02). The mean HbAlc value in CD children was higher than in the control subjects (p<0.01).A significant increase in the insulin requirement after 1 year in the GFD compliant children was found. There was a significant improvement in height-SDS after institution of GFD in the GFD-compliant children. Families of children with both T1D and CD reported higher burden than those affected by T1D only (p=0.001). The health care providers perceived family burden to increase with CD appearance (p<0.05). CONCLUSION: Our study supports the importance of screening for CD in children with T1D 1. The early treatment with GFD of biopsy-confirmed CD children promotes a significant catch-up growth and prevents a growth failure during the follow-up.

WHO Declares COVID-19 a Pandemic.

The World Health Organization (WHO) on March 11, 2020, has declared the novel coronavirus (COVID-19) outbreak a global pandemic (1). At a news briefing , WHO Director-General, Dr. Tedros Adhanom Ghebreyesus, noted that over the past 2 weeks, the number of cases outside China increased 13-fold and the number of countries with cases increased threefold. Further increases are expected. He said that the WHO is "deeply concerned both by the alarming levels of spread and severity and by the alarming levels of inaction," and he called on countries to take action now to contain the virus. "We should double down," he said. "We should be more aggressive." [...].

Insulin resistance and secretion indexes in healthy Italian children and adolescents: a multicentre study.

BACKGROUND AND AIM: To establish normal values of insulin resistance, secretion and sensitivity using respectively HOMA-IR, HOMA-beta% and QUICKI indexes in healthy Italian children and adolescents, based on fasting samples. METHODS: We determined HOMA-IR, HOMA-beta% and QUICKI at baseline in 142 healthy subjects from Pediatric Centres, aged 2.7 to 19 years (10.6 +/- 3.8, Mean +/- SD), with different Tanner's pubertal Stages (TS). None had hypo/hyperglycemia (fasting plasma glucose ranging from 3.6 to 5.6 mmol/l), obesity (BMI (kg/m2) 17.9 +/- 2.4, M +/- SD), or family history for diabetes mellitus. RESULTS: The HOMA-IR index slightly increases with Tanner's stage. As regards HOMA-beta% and QUICKI, a weak variation throughout puberty was observed. No significant correlation was observed between HOMA-IR, HOM A-beta%, QUICKI and BMI-SDS or chronologic age. CONCLUSIONS: Normal values of HOMA-IR, HOMA-beta% and QUICKI are useful tools in the clinical and epidemiological practice for baseline screening and follow-up of subjects at risk for type 2 diabetes mellitus.

Haemolysis during diabetic ketoacidosis treatment in two girls with incomplete glucose-6-phosphate dehydrogenase deficiency.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency is a typical X-linked enzymopathy causing severe haemolytic anaemia in males, and mild to moderate anaemia in homozygous females. Haemolysis due to G6PD deficiency in patients with type 1 diabetes mellitus (T1DM) has been principally reported in males, but is uncommon. During the last 10 years 2 girls with an unknown incomplete G-6-PD deficiency showed haemolysis during the treatment of DKA at the onset of T1DM. We speculate that the patients here described showed haemolytic anaemia as a phenotypic expression of the lyonization process and/or an uncommon penetrance of the defective gene. Haemolysis occurred when blood glucose levels were returning to normal values. In normal red blood cells, G6PD provides a source of reducing power for maintaining sulphydryl groups (SH) and facilitating the detoxification of free radicals and peroxides. During insulin i.v. infusion the copious glucose available due to the hyperglycaemia progressively decreased and affected the old red blood cells to generate nicotinamide adenine dinucleotide (NADPH), a crucial source for energy-dependent functions. This NADPH loss could have enhanced the rate of all factors such as methaemoglobin generation, Heinz body formation, and lipid peroxidation, which occur in G6PD deficient cells in response to both endogenous and exogenous oxidants. The direct consequence of this phenomenon is an increased erytrocyte oxidant sensitivity and a loss of sulphydryl group availability causing premature red blood cell destruction.

Sedentary lifestyle in active children admitted to a summer sport school.

Aim of this study was to investigate the sedentary patterns of school-aged active children admitted to a summer sport school. One hundred-twelve children aged 9-11 years were interviewed through a questionnaire about sedentary behaviours and nutrition habits. Seventy-one per cent of children reported they watch TV seven days a week, girls less than boys (84 +/- 45 minutes vs. 110 +/- 75 minutes) (t = 2.056; p = 0.042). The habit of TV viewing during meals was widespread (38% breakfast, 31% lunch, 62% dinner, 18% every meal). The prevalence of overweight or obesity (58.5%) was significantly higher among boys watching TV at dinner compared to the boys viewing TV only in the afternoon (35%) (chi2 = 4.976; p = 0.026). Fifty-seven per cent of children (65% boys) were accustomed to nibble snacks during TV viewing, and this habit was widespread in overweight or obese boys (chi2 = 4.546; p = 0.033). The dietary patterns of children watching TV include more snack foods and fewer fruits than the dietary patterns of the same children exercising (chi2 = 4.199 p = 0.040). Also in active children the habit to watch television is widespread and, in spite of the tendency to physical activity, 46% of them were overweight or obese; in fact the time spent looking at a TV may be associated to overweight/obesity and this relationship could be explained by the amount of high-density foods consumption during inactivity. Playing video games, read a book and listening to music are sedentary lifestyle patterns but these seem not to represent a risk factor for an increased BMI.

Disturbed eating behavior in pre-teen and teenage girls and boys with type 1 diabetes.

AIM: To investigate Disturbed Eating Behavior (DEB) and eating patterns in the context of a teenage population with T1D. METHODS: DEB was investigated using Eating Disorder Examination (EDE) test by a psychologist. Questions regarding insulin dosage manipulation or omission to obtain decrease in weight were added. Specific behavioral items from the EDE were used to define DEB: Objective Binge-eating, Self-induced Vomiting for weight control; the use of Diuretics, Laxatives or Insulin Omission for weight loss. Some EDE items provided information about four composite subscales which assesse Restraint, Eating concern, Shape concern and Weight concern. RESULTS: Shape and Weight concern showed significantly higher scores than those observed in the other two subscales (p=0.021). Average scores of each subscale resulted significantly higher in girls than in boys as well as in teen than in pre-teen participants. Objective binge eating (20%) and insulin dosage omission or reduction (17.6%) were the most common DEB (p<0.03). Forty-one percent of participants reported to consume three, 25% four and 34% five meals daily. A significantly lower proportion of females than males resulted to consume breakfast and mid-afternoon snacks. CONCLUSIONS: Findings from this study suggest that caregivers working in pediatric diabetes units should be alert in order to discover some DEB such as medication omission and binge-eating, all indicative symptoms of dissatisfaction of the body and psychological distress in diabetes management.

Clinical utility of beta-hydroxybutyrate measurement in the management of physiological ketosis at home in children under 5.

AIM: To verify the possible advantages of 3- ß-hydroxybutyrate (3HB) measurement compared to urinary assay of ketones during an intercurrent disease managed at home. METHODS: Twelve Pediatricians were asked to enroll at least 4 patients aged 3 to 5 years, affected by an intercurrent illness and showing at least one of symptoms reliable to ketosis. Recruited patients were submitted to the simultaneous assay of 3HB in capillary blood and ketones in urine at 3 (T3) and 6 hours (T6) from the first measurement (T0). For urinary and blood ketone detection commercial tests were used. RESULTS: Thirty-eight children (4.36±2.60 years old; 25 boys) were enrolled into the study. At T0 all children showed 3HB levels (1.2-3.2 mmol/L), but only 10 of them (26.3%) associated also urinary ketone bodies (2 to 4+). In response to 3 hour treatment (T3) with a glucose solution, 3HB values decreased in 19 (0,8-1,8 mmol/L) and normalized in 13 children (<0.2 mmol/L); while ketonuria disappeared in only 2 patients, it was confirmed in 8 and appeared (4+) the first time in the remaining 28 children. At T6 3HB levels fell definitively within the normal range in all children, while ketonuria was still present (2+) in 9 patients (23%). The pediatricians reported two limitations about blood 3HB dosage compared to the urinary test: the invasiveness of capillary blood collection, and the cost of supplies for finger pricking, reagent strips and reflectance meter. CONCLUSIONS: 3HB monitor in capillary blood is more effective and clinically more useful in diagnosing and managing of an ongoing ketosis in children with a mild infective disease than ketones detection in the urine. These advantages are mitigated by the cost of 3HB measurement.

Available tools for primary ketoacidosis prevention at diabetes diagnosis in children and adolescents. "The Parma campaign".

Diabetic Ketoacidosis (DKA) is a leading cause of death and disability in children with type 1 diabetes (T1D) and it is generally related to a long duration of misdiagnosed hyperglycaemia-related symptoms. Shortening this latency period could be a winning preventive strategy. It is intuitively easy to achieve this goal when other members with T1D in a family exist, as well as during the follow-up of the relatives of patients with T1D positive for genetic, immunological or metabolic markers. An incidental blood glucose level over 100 mg/dl found in children without history for T1D has been reported as indicative of a progressive beta-cell dysfunction and so it may be recommended for DKA prevention at diabetes diagnosis. More encouraging results have been obtained with a campaign of information promoted in schools and in paediatricians' offices, centred on the earliest symptom of diabetes (nocturnal enuresis in a dry child) as reported by 89% of parents. During 8 years of this campaign, the cumulative frequency of DKA dropped from 78% to 12.5% and its long effects were still observed several years after it was promoted. The Parma campaign obtained a reduction in DKA incidence at diabetes diagnosis never found before. The key-success of this campaign may be attributed to the communication of a valuable and reliable message easy to understand and follow; information toward a large population through school and paediatric consultation; involvement of family paediatricians and Parents' Association; free access to experienced health providers in diabetes diagnosis.

Could infantile interactive drawing technique be useful to promote the communication between children with Type-1 diabetes and pediatric team?

AIM: to finding what young patients with type-1 diabetes (T1D) knows about their body and also on their illness in perspective to tailor educational interventions to their real ability to understand. METHODS: the present study involved 68 children with T1D , 5 to 14 years old with a duration of diabetes ranging from 2 to 6 years and a total HbA1c mean value of 7.96±0.87%. The sample was divided into two age Groups: 28 children 5 to 10 years old were gathered in the Group 1 and 40 teenagers aged from 11 to 14 years in the Group 2. These patients were invited to draw over a white paper using a black pencil "The human body as it is made inside". Subsequently they were asked to explain: "what is diabetes?" and "where does insulin go?". According to the methodology of the "interactive drawing", the interviewer interacted with the children while drawing, forcing them to verbalize the reasons for their choices, to justify their proceeding, to explain their plan and then to explicit their theories. Drawings and replies were classified as Correct, Correct-but-Incomplete and Incorrect. RESULTS: the overall production of correct/correct-but-incomplete drawings was 83.82% vs 16.20% of the incorrect ones. One-hundred of the children who have produced a correct drawing supplied also a correct verbal reply, whereas 100% of the children who have produced an incorrect drawing was unable to supply any information on diabetes or about insulin. Both younger and older subjects who produced a complete-but-incorrect drawing appeared to have misunderstood the action of insulin therapy (only 23% and 17% of correct replies). Children who produced incomplete drawings and provided incorrect replies to the questions about their disease showed also a HbA1c mean value higher (8.36±0.97%) compared to the children who drew and answered correctly (p=0.0023). CONCLUSIONS: the operative epistemic approach could represent a promising tool for a health professional team to verify the real understanding acquired by a child about T1D, and to provide pediatrician a guideline to directly communicate with his patient.
