Abstract

INTRODUCTION Obesity is the most common nutritional disorder in children from western or westernized countries, with a relevant impact on public health. Obese children have a high chance (40-80%) of [...], BACKGROUND/OBJECTIVES: Little is known on the relationship between obesity and hydration levels in children. This study assessed whether and by which mechanisms hydration status differs between obese and non-obese children. SUBJECTS/METHODS: Hydration levels of 86 obese and 89 normal weight children (age: 7-11 years) were compared. Hydration was measured as the average free water reserve (FWR = urine output/24 h minus the obligatory urine output [total 24 h excreted solutes/97th percentile of urine osmolality of children with adequate water intake, that is, 830 mOsm/kg]) over 2 days. Three days of weighed dietary and fluid intakes were recorded. Non-parametric tests were used to compare variables that were skewed and to assess which variables correlated with hydration. Variables mediating the different hydration levels of obese and normal weight children were assessed by co-variance analysis. RESULTS: Obese children were less hydrated than normal weight peers [FWR= median (IQR): 0.80 (-0.80-2.80) hg/day vs 2.10 (0.10-4.45) hg/day, P < 0.02;32% of obese children vs 20% of non-obese peers had negative FWR, P < 0.001]. Body mass index (BMI) z-score (z-BMI) and water intake from fluids correlated with FWR (ρ = - 0.18 and 0.45, respectively, both P < 0.05). Water intake from fluids completely explained the different hydration between obese and normal weight children [FWR adjusted for water from fluids and z-BMI = 2.44 (0.44) hg vs 2.10 (0.50) hg, P = NS;B coefficient of co-variation between FWR (hg/day) and water intake from fluids (hg/day) = 0.47, P < 0.001]. CONCLUSIONS: Obese children were less hydrated than normal weight ones because, taking into account their z-BMI, they drank less. Future prospective studies are needed to explore possible causal relationships between hydration and obesity.

Abstract

Background There are no Italian data regarding the strategies for preventing neonatal group B streptococcal (GBS) infection. We conducted a national survey in order to explore obstetrical, neonatal and microbiological practices for the GBS prevention. Methods Three distinct questionnaires were sent to obstetricians, neonatologists and microbiologists. Questionnaires included data on prenatal GBS screening, maternal risk factors, intrapartum antibiotic prophylaxis, microbiological information concerning specimen processing and GBS antimicrobial susceptibility. Results All respondent obstetrical units used the culture-based screening approach to identify women who should receive intrapartum antibiotic prophylaxis, and more than half of the microbiological laboratories (58%) reported using specimen processing consistent with CDC guidelines. Most neonatal units (89 out of 107, 82%) reported using protocols for preventing GBS early-onset sepsis consistent with CDC guidelines. Conclusions The screening-based strategy is largely prevalent in Italy, and most protocols for preventing GBS early-onset sepsis are consistent with CDC guidelines. However, we found discrepancies in practices among centers that may reflect the lack of Italian guidelines issued by public health organizations.

Abstract

Summary13 male New Zealand rabbits were injected with two different doses (25 μg/Kg and 100 μg/Kg) of human platelet factor 4 antigen (PF4). The disappearance of the protein was extremely fast with an half-life for the fast component of 1.07 ± 0.16 and 1.76 ± 0.11 min respectively. The half-life for the slow component, detectable only with the highest dosage, was 18.8 min.The administration of 2500 I.U. of heparin 30 min after PF4 administration induced a partial release of the injected protein and its clearance from plasma was slow, with half-life of 23.3 ± 5.9 min and 30.9 ± 2.19 min respectively.

Abstract

Twelve male New Zealand rabbits were injected with 21 micrograms/kg of human platelet factor 4 antigen (PF4). The decay of the protein followed a monoexponential curve for the first 5 mins, with a half-life (t 1/2) of 1.94 mins and a calculated concentration at 0 time (CO) of 79.4 ng/ml. Five rabbits were pre-treated with heparin (2.500 I.U. i.v.) and 3 mins later were injected with the same amount of PF4. PF4 decay followed a monoexponential curve with a t 1/2 of 25.3 mins, and with CO of 380.8 ng/ml. This value is not greatly different from the one calculated assuming an immediate and uniform distribution in plasma (482.7 ng/ml for a plasma volume of 43.5 ml/kg). The 12 rabbits injected with PF4 were divided in 3 groups, in which heparin was given at 10', 30' or 60' after PF4, respectively. After heparin the peak levels of PF4 were 139.9 ng/ml, 65.3 ng/ml and 52.7 ng/ml, respectively. The following monoexponential PF4 decay had t 1/2 of 20.7, 25.6 and 26.0 mins, respectively. In a separate group of 4 animals, we studied heparin decay after an intravenous bolus of 2.500 I.U. Heparin decay could not be described by a monoexponential equation and was different from the decay of PF4 injected after heparin. On the basis of the present data we suggest the presence of an immediate component of PF4 decay, most likely due to uptake by the tissues. Heparin pretreatment may avoid this uptake process.

Abstract

Background and Aims: The monitoring of yearly distributions of HbA 2 measured has been indicated as a reliable indicator of worldwide standardization., Materials and Methods: Measurements/year of HbA 2 have been collected over three consecutive years in 15 Italian laboratories each using the same analytical method over three years period. HbA 2 distributions, cleaned of replicated measurements, were compared by the overlapping area of the raw probability density functions expressed by coefficient eta (η), and by comparing the reference intervals for the central part of each distribution estimated by the indirect method refineR using the R package "refineR"., Results: According to the overlapping areas analysis the distributions/year of the data provided by 4 centers able to perform at least 1000 measurements/year were similar in 2 consecutive years. Moreover, the reference intervals provided by 2 centers using the same analytical methods in two separate locations over the three consecutive years, were very similar. The highest overlap (99.7 %) was observed in one center over two consecutive years. The overlapping areas were very high (93.6-95.7%) in 8 out of 9 inter-comparisons., Conclusion: Despite the limitations of this study the yearly distribution of the HbA 2 measured in various centers appears a reliable tool to test HbA 2 standardization over different centers using different analytical methods., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Background/aim: The antibody titer of vaccine-preventable diseases in pediatric patients who underwent chemotherapy was assessed in order to evaluate the seroprotection after treatment and the feasibility and the efficacy of a policy of revaccination., Methods: Serum antibody titers of 55 patients for hepatitis B (HBV), rubella, varicella-zoster (VZV), measles, mumps, polio viruses, Clostridium tetani ( C. tetani ) and Streptococcus pneumoniae ( S. pneumoniae ) were analysed.Results: After chemotherapy, a lack of protective antibody titers against HBV, rubella, VZV, measles, mumps, polio viruses, C. tetani , and S. pneumoniae was found in 53%, 45%, 46%, 46%, 43%, 21-26%, 88% and 55% of patients, respectively. In 49 of 55 patients who were tested both before and after chemotherapy for at least a pathogen, the loss of immunity for HBV, rubella, VZV, measles, mumps, polio viruses and C. tetani was respectively 39%, 43%, 38%, 42%, 32%, 33%, and 80%. A low number of B-lymphocytes was associated with the loss of immunity against measles (p=0.04) whereas a high number of CD8+ T-lymphocytes was associated with the loss of immunity against VZV (p=0.03). A single booster of vaccine dose resulted in a seroprotection for HBV, rubella, VZV, measles, mumps, polio viruses, C. tetani and S. pneumoniae in 67%, 83%, 80%, 67%, 33%, 100%, 88% and 67% of patients, respectively., Conclusions: We confirm that seroprotection for vaccine-preventable diseases is affected by treatment for pediatric malignancy. A single booster dose of vaccine might be a practical way to restore vaccine immunity in patients after chemotherapy., Competing Interests: Competing interests: The authors declare no conflict of Interest.

Abstract

Background & Aims: Celiac disease is one of the most common diseases worldwide, with an apparent trend of increasing prevalence. We investigated the prevalence of celiac disease in children in Italy in 2015-2016 and compared that with data from 25 years ago., Methods: We screened 4570 children (5-11 years old, 80.1% of the eligible population) from metropolitan areas of Ancona and Verona for HLA genes associated with increased risk of celiac disease, and for total serum levels of IgA and IgA class anti-tissue transglutaminase in HLA positives. Diagnoses of celiac disease were confirmed by detection of anti-endomysial antibody and analysis of intestinal biopsies. The prevalence of celiac autoimmunity and celiac disease were calculated and compared with values from the same geographical area during the years 1993-1995, after adjustment for the different diagnostic algorithm., Results: We identified 1960 children with celiac disease-associated haplotypes (43% of children screened; 95% CI, 40.8%-45.2%). The prevalence of celiac disease autoimmunity in the HLA-positive subjects was 96/1706 (5.62%; 95% CI, 4.53%-6.71%) and 54 of these children satisfied the diagnostic criteria for celiac disease. In the eligible population there were other 23 known cases of celiac disease. The overall estimated prevalence of celiac disease was 1.58% (95% CI, 1.26%-1.90%); this value is significantly higher than the 1993-1995 adjusted prevalence (0.88%; 95% CI, 0.74%-1.02%)., Conclusions: We found the prevalence of celiac disease in children in Italy to be greater than 1.5%; this value has increased significantly over the past 25 years. Studies are needed to determine the causes of this large increase., (Copyright © 2020 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Abstract

Strongyloides stercoralis is a soil-transmitted helminth widely diffused in tropical and subtropical regions of the world. Autochthonous cases have been also diagnosed sporadically in areas of temperate climate. We aimed at defining the epidemiology of strongyloidiasis in immigrants and Italians living in three northern Italian Regions. Screening for S. stercoralis infection was done with serology, confirmation tests were a second serological method or stool agar culture. A case-control approach was adopted and patients with a peripheral eosinophil count ≥ 500/mcL were classified as cases. Of 2,701 individuals enrolled here 1,351 were cases and 1,350 controls; 86% were Italians, 48% women. Italians testing positive were in 8% (97/1,137) cases and 1% (13/1,178) controls (adjusted odds ratio (aOR) 8.2; 95% confidence interval (CI): 4.5-14.8), while positive immigrants were in 17% (36/214) cases and in 2% (3/172) controls (aOR 9.6; 95% CI: 2.9-32.4). Factors associated with a higher risk of infection for all study participants were eosinophilia (p < 0.001) and immigration (p = 0.001). Overall, strongyloidiasis was nine-times more frequent in individuals with eosinophilia than in those with normal eosinophil count., Competing Interests: Conflicts of Interest: None declared., (This article is copyright of The Authors, 2016.)

Abstract

Objective: This multicenter study aims to evaluate HE4, CA125 and risk of ovarian malignancy algorithm (ROMA) performance in the differential diagnosis of epithelial ovarian cancer (EOC)., Methods: A total of 405 patients referred to gynecological oncologist with suspicious pelvic mass requiring a surgery for identification of EOC were consecutively enrolled; 387 patients satisfied inclusion criteria: 290 benign diseases; 15 borderline neoplasia and 82 tumors (73 EOC)., Results: Good diagnostic performance in discriminating benign from EOC patients was obtained for CA125, HE4 and ROMA when calculating optimal cut-off values: premenopause, specificity (SP) >86.6, sensitivity (SN) >82.6, area under the curves (AUC)≥0.894; postmenopause, SP>93.2, SN>82, AUC≥0.928. Fixing SP at 98%, performance indicators obtained for benign vs EOC patients were: premenopause, SN:65.2%, positive predictive value (+PV): 75%, positive likelihood ratio (+LR): 26.4 for CA125; SN:69.6%, +PV:76.2%, +LR:28.1 for HE4; SN:69.6%, +PV: 80%; +LR:35.1 for ROMA; postmenopause, SN:88%, +PV: 95.7%, +LR:38.7 for CA125; SN:78%, +PV:95.1%, +LR:34.3 for HE4; SN:88%, +PV:97.8%, +LR:77.4 for ROMA. When using routine cut-off thresholds, ROMA showed better well-balanced values of both SP and SN (premenopause, SN:87%, SP:86.1%; postmenopause, SN:90%; SP:94.3%)., Conclusions: Overall, ROMA showed well balanced diagnostic performance to differentiate EOC from benign diseases. Meaningful differences of +PVs and +LRs between HE4 and CA125 suggest that the two markers may play at least in part different roles in EOC diagnosis, with HE4 seeming to be more efficient than CA125 in ruling in EOC patients in the disease group, also in early stages tumors, both in pre and postmenopause., (Copyright © 2016.

Abstract

To simplify collection and transport of blood for HbA1c measuring, we have studied the use of a special paper that absorbs a defined volume of capillary blood and quickly dries it (dried blood-spot, DBS). The DBS can be sent to a central laboratory using regular postal service and without temperature control. This system differs greatly from other proposed DBS methods for HbA1c because it overcomes the haemoglobin alterations during the drying and storing processes, that otherwise make this analysis unreliable. We have developed a special treatment of the paper before collection that stabilises the HbA1c molecule excellently in dried blood samples, allowing accurate HPLC analysis even two weeks after collection. This method has been applied in a "blind" study in which HbA1c values determined in 97 DBS coming from an hospital diabetes care centre were compared with those obtained from parallel venous blood samples.

Abstract

A commercial heparin preparation, a heparin fraction with a molecular weight of 12,000 Daltons, heparan sulfate, dermatan sulfate obtained from hog mucosa, and mesoglycan, an heparinoid obtained from calf aortic intima were investigated. Commercial mucous heparin had a stimulatory effect on platelet aggregation induced by ADP, while the others failed to do so. Dermatan sulfate had a dose dependent inhibition and commercial mucosal heparin, a dose dependent stimulation, on serotonin release induced by ADP. Both the commercial mucosal heparin and dermatan sulfate showed an inhibition and the other glycosaminoglycans (GAGs) a negligible effect on collagen induced platelet aggregation. The collagen induced serotonin release was clearly reduced by all GAGs; heparan sulfate had this activity only at the highest doses used. Commercial mucosal heparin produced the highest activity on clotting systems as measured by activated partial thromboplastin time, while mesoglycan had the strongest anti-factor Xa specific activity as measured by a clotting assay. Dermatan sulfate was the weakest on both assays. When we injected intravenously an equivalent amount (about 60 mg) of heparin fraction, heparan sulfate, dermatan sulfate and mesoglycan in three different volunteers with an interval of 20 days after each injection, we had an immediate platelet factor 4 (PF4) release only with heparin fraction, heparan sulfate and mesoglycan. Heparin fraction and mesoglycan, in spite of having a wide discrepancy in anticoagulant effect, caused almost the same PF4 release. GAGs which can neutralize PF4 and which can also have specific anti-factor Xa activity could represent a great advantage in thrombosis prophylaxis.

Abstract

Beta-thromboglobulin and platelet factor 4 are the two best characterized platelet-specific proteins. They are stored in the platelet alpha-granules and released during platelet activation. Their physiological function is unknown. PF4 has high anti-heparin activity, whilst beta-TG does not. Certain factors can affect the plasma level of one or both of these two proteins and these must be borne in mind whenever the evaluation of beta-TG and PF4 are thought to represent true in vivo platelet activation: their artificial release due to sample collection and processing, the in vivo release of PF4 induced by heparin, and the elevation of beta-TG due to renal failure. What really represents an abnormal level of beta-TG and PF4 is unknown, since we do not know their pathophysiology. At present, however, the platelet-specific proteins, even if they are considered as 'markers' of platelet activation, do not necessarily reflect the severity of the cardiovascular disorders nor do they signal thrombus formation, as thrombosis is a consequence of several interacting factors.

Abstract

A new patient with factor VII Padua abnormality is presented. The propositus is a 70 old man who showed a mild bleeding tendency characterized by occasional epistaxis and a laboratory pattern of prolonged prothrombin time corrected by normal serum, normal partial thromboplastin time and normal Thrombotest. Factor VII activity was 7% using rabbit brain thromboplastin and 105% of normal using ox-brain thromboplastin. Intermediate levels were found by using thromboplastin of human origin. Factor VII cross-reacting material was normal. Parents were not consanguineous but both came from the same area. Two children of the propositus were found, as expected, to be homozygous for the abnormality. No relationship could be traced between the propositus and the other homozygous patients already reported. However, the patient came from the same geographic area, namely the Piave river valley in northeastern Italy. The discovery of the present patient, the fifth in four years, indicates that the defect might be more frequent than originally assumed.

Abstract

Several investigators have reported an altered platelet function in diabetes mellitus as measured by elevated levels of platelet specific proteins platelet factor 4 (PF4) and B-thromboglobulin (BTG). We studied 20 insulin dependent (IDD), 20 non insulin dependent (NIDD) diabetic males without overt clinical symptoms of cardiovascular disorders and 30 normal controls. We evaluated PF4, BTG and heparin released platelet factor 4 (HR-PF4) as measured 2.5 minutes after a bolus injection of 5,000 I.U. of a commercial mucous heparin. The patients showed normal levels of both PF4 and BTG. Furthermore HR-PF4 failed to show statistically significant variation between patients and controls. However when the diabetics were divided on the basis of the duration of the disease, the IDD had an increased HR-PF4 mean level and the trend became statistically significant when diabetes existed more than 17 years (patients HR-PF4 149.1 ng/ml, range 17.3-194; controls HR-PF4 110.9 ng/ml range 50-160, less than p less than 0.05). NIDD failed to reveal the same pattern. Although the significance of HR-PF4 is unknown, insulin dependent diabetes mellitus after many years could cause a potentially dangerous, silent vascular damage with enhanced platelet vessel wall interaction as measured by an elevated HR-PF4.

Abstract

When heparin is injected intravenously, it can induce an immediate release of platelet factor 4 PF4), probably from the non-platelet pool of endothelial cells. We evaluated this release in a group of normal subjects and patients with cardiovascular disorders or thrombocytosis after an intravenous injection of a bolus of 5,000 I.U. of a commercial mucous heparin. The mean level in normals was 102 +/- 32 (range 50-160) ng/ml and no correlation was found before and after heparin injection between PF4 and heparin level, body weight or platelet count. Only three cardiovascular patients had an elevated level of PF4 released by heparin (HR-PF4) that could be the expression of an increased platelet turnover, whereas all the patients with thrombocytosis had an extremely elevated level of HR-PF4. These patients have much more PF4 available for the binding sites of endothelial cells since only a small percentage of potential binding sites are normally occupied "in vivo". Although no correlation could be found between platelet count and HR-PF4 in subjects with a normal platelet count or in patients with thrombocytosis there was a positive correlation, however, when all the cases were considered together. The other proteins with heparin affinity, B-thromboglobulin, antithrombin III and fibronectin were not influenced by a bolus of heparin and did not correlate in normals as well in patients with HR-PF4.
