The Mutual Interplay between Bone, Glucose and Lipid Metabolism: The Role of Vitamin D and PTH.

Background: We sought to investigate the mutual interplay between bone, glucose and lipid metabolism in a wide cohort of community-based subjects.

Methods: We studied 1240 blood donors (F/M ratio 1/3.2, mean age 41.

Defective Leukocyte β2 Integrin Expression and Reactive Oxygen Species Production in Neonates.

Neonates are highly susceptible to bacterial infections, which represent a major source of mortality and morbidity in this age category. It is recognized that β2 integrins play a critical role in innate immunity by mediating leukocyte vascular adhesion, transmigration and bacterial phagocytosis. Therefore, we aimed to assess if the impaired immune functions seen in newborns may derive, in part, from a transient insufficient β2 integrin expression.

Mineral metabolism abnormalities in patients with prostate cancer: a systematic case controlled study.

Purpose: Prostate cancer is the most common tumor in men. To the best of our knowledge a systematic assessment of bone and mineral abnormalities has not been performed in prostatic cancer patients consecutively enrolled.

Methods: This study was therefore carried out to investigate changes of skeletal and mineral metabolism in patients with prostate cancer (n  = 69).

Etiology, clinical outcome, and laboratory features in children with neutropenia: analysis of 104 cases.

Background: Neutropenia is not uncommon in childhood. The aim of our study was to analyze the underlying causes of neutropenia and to evaluate its clinical significance in a series of children referred to our center.

Methods: One hundred and four consecutive children with neutropenia were enrolled in this study.

Increased levels of acute-phase inflammatory proteins in plasma of patients with sporadic CJD.

Objective: Screening plasma samples from patients with sporadic Creutzfeldt-Jakob disease (CJD) to discover diagnostic biomarkers.

Methods: Plasma samples were collected from 17 patients with sporadic CJD, 17 patients with Alzheimer disease (AD), and 20 healthy subjects. A 2-phase screening was carried out using quantitative protein mass spectrometry.

Maternal C-reactive protein at hospital admission is a simple predictor of funisitis in preterm premature rupture of membranes.

Aim: To analyze the prognostic value of maternal serum C-reactive protein (CRP) in predicting funisitis in patients with preterm premature rupture of membranes (pPROM).

Methods: 66 patients (gestational age 24-33 weeks) hospitalized 1-12 h after pPROM were enrolled. White blood cell count (WBC), platelet count (PLT) and plasma concentration of CRP were assessed every 3 days.

C reactive protein and procalcitonin: reference intervals for preterm and term newborns during the early neonatal period.

Background: There is still no study evaluating the influence of gestational age (GA) per se on C reactive protein (CRP) and procalcitonin (PCT) reference intervals. We therefore investigated how length of gestation, age (hours), and prenatal and perinatal variables might influence the levels of CRP and PCT. We also determined 95% age-specific reference intervals for CRP and PCT in healthy preterm and term babies during the early neonatal period.

Functional and morphological vascular changes in pediatric nonalcoholic fatty liver disease.

Unlabelled: Nonalcoholic fatty liver disease (NAFLD) has been consistently found to be associated with features of the metabolic syndrome (MS), a condition carrying a high risk of cardiovascular events. The present study aimed to determine whether, in children and adolescents, NAFLD is atherogenic beyond its association with MS and its components. We assessed both flow-mediated dilation of the brachial artery (FMD) and carotid intima-media thickness (cIMT), along with lipid profile, glucose, insulin, insulin resistance, and high-sensitivity C-reactive protein (CRPHS), in 250 obese children, 100 with and 150 without NAFLD, and 150 healthy normal-weight children.

Strong intra- and inter-continental differentiation revealed by Y chromosome SNPs M269, U106 and U152.

More than 2700 unrelated individuals from Europe, northern Africa and western Asia were analyzed for the marker M269, which defines the Y chromosome haplogroup R1b1b2. A total of 593 subjects belonging to this haplogroup were identified and further analyzed for two SNPs, U106 and U152, which define haplogroups R1b1b2g and R1b1b2h, respectively. These haplogroups showed quite different frequency distribution patterns within Europe, with frequency peaks in northern Europe (R1b1b2g) and northern Italy/France (R1b1b2h).

Serum uric acid and its association with metabolic syndrome and carotid atherosclerosis in obese children.

Objective: The association between hyperuricemia, metabolic syndrome (MS), and atherosclerotic vascular disease has been reported in adults, but very little is known about this association in children. The aims of our study were to ascertain the correlates of uric acid (UA) in a sample of obese children, and to investigate whether UA is associated with carotid intima-media thickness (IMT) independently from classical risk factors including MS.

Methods: We analyzed carotid IMT along with serum triglycerides, total and high-density lipoprotein cholesterol, glucose, insulin, insulin resistance index (as homeostasis model assessment of insulin resistance), alanine aminotransferase, gamma-glutamyltransferase, creatinine, and UA in 120 obese children and 50 healthy control children.

Tracing past human male movements in northern/eastern Africa and western Eurasia: new clues from Y-chromosomal haplogroups E-M78 and J-M12.

Detailed population data were obtained on the distribution of novel biallelic markers that finely dissect the human Y-chromosome haplogroup E-M78. Among 6,501 Y chromosomes sampled in 81 human populations worldwide, we found 517 E-M78 chromosomes and assigned them to 10 subhaplogroups. Eleven microsatellite loci were used to further evaluate subhaplogroup internal diversification.

Phylogeographic analysis of haplogroup E3b (E-M215) y chromosomes reveals multiple migratory events within and out of Africa.

We explored the phylogeography of human Y-chromosomal haplogroup E3b by analyzing 3401 individuals from five continents. Our data refine the phylogeny of the entire haplogroup, which appears as a collection of lineages with very different evolutionary histories, and reveal signatures of several distinct processes of migrations and/or recurrent gene flow that occurred in Africa and western Eurasia over the past 25000 years. In Europe, the overall frequency pattern of haplogroup E-M78 does not support the hypothesis of a uniform spread of people from a single parental Near Eastern population.
