Purpose: We have recently demonstrated a significant association between osteoporosis (Op) and metabolic syndrome (MetS) in Caucasian women examined by Dual-energy X-ray absorptiometry (DXA) for suspected Op. This cross-sectional study was performed to evaluate the association between MetS and Op in Caucasian men enrolled in the same geographical area, with identical criteria and in the same time range., Methods: Among subjects enrolled in the SIMON study, we selected the medical records of all free-living men who performed a contextual evaluation of both bone mineral density (BMD) by DXA and MetS constitutive elements (arterial blood pressure, waist circumference, serum levels of triglycerides, high-density lipoprotein cholesterol, and fasting glucose). All enrolled subjects refer to "COMEGEN" general practitioners' cooperative operating in Naples, Southern Italy., Results: Overall, the medical records of 880 men were examined. No significant association between MetS and Op was observed. Among MetS constitutive elements, waist circumference was inversely related to Op risk., Conclusion: In Caucasian men examined by DXA for suspected Op, no significant association was observed between Op and MetS. The study results contrast to those observed in women enrolled in the same geographical area, with identical criteria and in the same time range and may be related to sexual dimorphism occurring in clinical expressiveness of both MetS and Op., (© 2021.

Purpose: Osteoporosis (Op) and metabolic syndrome (MetS) are two common disorders showing common pathogenic patterns. This cross-sectional study was performed to evaluate if MetS and its constitutive elements are associated to an increased risk of low bone mineral density (BMD) in free-living women examined by Dual-energy X-ray absorptiometry (DXA) for suspected Op., Methods: 13,182 free-living Caucasian women referring to "COMEGEN" general practitioners cooperative operating in Naples, Italy, performed a contextual evaluation of BMD by DXA and all MetS constitutive elements (systolic and diastolic blood pressure, waist circumference, serum levels of triglycerides, high-density lipoprotein cholesterol, and fasting glucose) between June 1st 2008 and May 31st 2018. Subjects aged less than 40 years or with signs or symptoms suggestive of secondary Op were excluded from the study., Results: MetS is associated to an increased risk of low BMD (Odds Ratio 1.19; 95% Confidence Interval 1.08-1.31). Among MetS constitutive elements, hypertension was associated to increased risk of low BMD, whereas high fasting glucose level/diabetes were associated to reduced risk of low BMD., Conclusions: The significant association between Op and MetS in free-living women examined by DXA for suspected Op suggests the advisability of a contextual evaluation of both disorders in this setting.

Objectives: Because it is involved in calcium homeostasis, vitamin D is a prohormone with many implications for health, especially bone health. Hypovitaminosis D is considered pandemic worldwide, with important health health consequences. The aim of our study was to evaluate vitamin D levels in children living in a southern region of Italy with high exposure to sunlight for at least 5 mo a year along with contributing factors., Methods: A total of 1484 children and adolescents (age 0.02-17.74 y) living in the Apulia region (Southern Italy) were studied. Serum 25-hydroxyvitamin D (25[OH]D) concentrations were assessed and vitamin status defined as follows: deficiency with serum 25(OH)D < 20 ng/mL, insufficiency from 20 to 29.9 ng/mL, and sufficiency with serum 25(OH)D from 30 to 100 ng/mL., Results: The median serum 25(OH)D levels were 20.2 ng/mL (interquartile range, 14.5-26.4 ng/mL): 48.9% of the overall population had 25(OH)D < 20 ng/mL and only 15% had sufficient 25(OH)D values. There was an inverse association between blood levels of 25(OH)D and age (P < 0.001, ρ: -0.113). Significant 25(OH)D variations were recorded according to the season in which blood samples were drawn, but even during summer only 32.6% of analyzed children had sufficient 25(OH)D levels., Conclusions: More than 80% of our population had 25(OH)D less than sufficiency cutoff levels. Results highlight a high prevalence of 25(OH)D deficiency in our area, even during summer. It is important to establish screening, supplementation guidelines, and pediatric cutoff levels to optimize vitamin D status in children, taking into account age, nutritional status, and seasonality., (Copyright © 2020 Elsevier Inc.

Osteoporosis and nephrolithiasis are common multifactorial disorders with high incidence and prevalence in the adult population worldwide. Both are associated with high morbidity and mortality if not correctly diagnosed and accurately treated. Nephrolithiasis is considered a risk factor for reduced bone mineral density. Aim of this retrospective longitudinal study was to evaluate if osteoporosis is a predictive factor for the nephrolithiasis occurrence. Free-living subjects referring to "COMEGEN" general practitioners cooperative operating in Naples, Southern Italy. Twelve thousand seven hundred ninety-four Caucasian subjects (12,165 female) who performed bone mineral density by dual-energy X-ray absorptiometry and have a negative personal history for nephrolithiasis. Subjects aged less than 40 years or with signs or symptoms suggestive of secondary osteoporosis were excluded from the study. In a mean lapse of time of 19.5 months, 516 subjects had an incident episode of nephrolithiasis. Subjects with osteoporosis had an increased risk of nephrolithiasis than subjects without osteoporosis (Hazard Ratio = 1.33, 95% Confidence Interval 1.01-1.74, p = 0.04). Free-living adult subjects over the age of 40 with idiopathic osteoporosis have an increased risk of incident nephrolithiasis, suggesting the advisability of appropriate investigation and treatment of the metabolic alterations predisposing to nephrolithiasis in patients with osteoporosis. The study protocol was approved by the ASL Napoli 1 Ethical Committee, protocol number 0018508/2018.

Purpose: The purpose of the study was to describe epileptologists' opinion on the increased use of remote systems implemented during the COVID-19 pandemic across clinics, education, and scientific meetings activities., Methods: Between April and May 2020, we conducted a cross-sectional, electronic survey on remote systems use before and during the COVID-19 pandemic through the European reference center for rare and complex epilepsies (EpiCARE) network, the International and the French Leagues Against Epilepsy, and the International and the French Child Neurology Associations. After descriptive statistical analysis, we compared the results of France, China, and Italy., Results: One hundred and seventy-two respondents from 35 countries completed the survey. Prior to the COVID-19 pandemic, 63.4% had experienced remote systems for clinical care. During the pandemic, the use of remote clinics, either institutional or personal, significantly increased (p < 10 -4 ). Eighty-three percent used remote systems with video, either institutional (75%) or personal (25%). During the pandemic, 84.6% of respondents involved in academic activities transformed their courses to online teaching. From February to July 2020, few scientific meetings relevant to epileptologists and routinely attended was adapted to virtual meeting (median: 1 [25th-75th percentile: 0-2]). Responders were quite satisfied with remote systems in all three activity domains. Interestingly, before the COVID-19 pandemic, remote systems were significantly more frequently used in China for clinical activity compared with France or Italy. This difference became less marked during the pandemic., Conclusion: The COVID-19 pandemic has dramatically altered how academic epileptologists carry out their core missions of clinical care, medical education, and scientific discovery and dissemination.

The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a Position Statement of Italian colorectal surgeons to address the surgical aspects of inflammatory bowel disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the general principles of surgical treatment of inflammatory bowel disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

Aim: To assess the relevance and generalizability across countries of concepts of the impact of Dravet syndrome beyond seizures, as recognized by families., Method: Caregivers of children with Dravet syndrome in four countries (Australia [n=8]; USA, UK, and Italy [all n=4]) participated in 1-hour qualitative telephone interviews, identifying key Dravet syndrome concepts. Interviews were recorded, transcribed, and, where necessary, translated into English for thematic analysis. Conceptual saturation was assessed and findings compared to the previously developed French conceptual disease model., Results: The most common seizure types reported by caregivers were tonic-clonic, absence, or focal-impaired awareness (localized/partial). Fever and physical activity were the most commonly reported triggers. Patient-relevant impacts included impairment in cognition, motor skills, communication, social skills, and behavioural functioning. Caregivers consistently reported negative social, physical, and family impacts. Concepts identified in the interviews showed similarity with the French conceptual model. Minor differences between countries are likely to reflect variations in health care systems., Interpretation: Findings in Italy, Australia, UK, and USA confirm that the key impacts of Dravet syndrome on children and caregivers identified in France are generalizable across countries. Key symptom and impact concepts relevant to children and parents should be targeted as critical outcomes in new therapy evaluations., What This Paper Adds: Relevance of the impact of Dravet syndrome on children and caregivers was confirmed across countries. Patient and caregiver-relevant Dravet syndrome impacts contribute to poorer health-related quality of life. Indirect seizure impacts were reported to be as important as direct impacts. Country-specific differences in concepts probably reflect differences in health care systems., (© 2019 Mac Keith Press.)

Background Steroid-sensitive nephrotic syndrome (SSNS) is a childhood disease with unclear pathophysiology and genetic architecture. We investigated the genomic basis of SSNS in children recruited in Europe and the biopsy-based North American NEPTUNE cohort. Methods We performed three ancestry-matched, genome-wide association studies (GWAS) in 273 children with NS (Children Cohort Nephrosis and Virus [NEPHROVIR] cohort: 132 European, 56 African, and 85 Maghrebian) followed by independent replication in 112 European children, transethnic meta-analysis, and conditional analysis. GWAS alleles were used to perform glomerular cis -expression quantitative trait loci studies in 39 children in the NEPTUNE cohort and epidemiologic studies in GWAS and NEPTUNE (97 children) cohorts. Results Transethnic meta-analysis identified one SSNS-associated single-nucleotide polymorphism (SNP) rs1063348 in the 3' untranslated region of HLA-DQB1 ( P =9.3×10 -23 ). Conditional analysis identified two additional independent risk alleles upstream of HLA-DRB1 (rs28366266, P =3.7×10 -11 ) and in the 3' untranslated region of BTNL2 (rs9348883, P =9.4×10 -7 ) within introns of HCG23 and LOC101929163 These three risk alleles were independent of the risk haplotype DRB1*07:01-DQA1*02:01-DQB1*02:02 identified in European patients. Increased burden of risk alleles across independent loci was associated with higher odds of SSNS. Increased burden of risk alleles across independent loci was associated with higher odds of SSNS, with younger age of onset across all cohorts, and with increased odds of complete remission across histologies in NEPTUNE children. rs1063348 associated with decreased glomerular expression of HLA-DRB1, HLA-DRB5, and HLA-DQB1. Conclusions Transethnic GWAS empowered discovery of three independent risk SNPs for pediatric SSNS. Characterization of these SNPs provide an entry for understanding immune dysregulation in NS and introducing a genomically defined classification., (Copyright © 2018 by the American Society of Nephrology.)

Context and Objective: Idiopathic central precocious puberty (iCPP) is defined as early activation of the hypothalamic-pituitary-gonadal axis in the absence of identifiable central lesions. Mutations of the makorin RING finger 3 (MKRN3) gene are associated with iCPP. We aimed to assess the frequency of MKRN3 mutations in iCPP and to compare the phenotypes of patients with and without MKRN3 mutations., Design: An observational study was carried out on patients recruited at pediatric hospitals in France and Italy. Forty-six index CPP cases were screened for mutations in the MKRN3 coding sequence: 28 index cases of familial cases and 18 cases did not report any familial history of CPP. The endocrine phenotype was compared between MKRN3 mutated and non-mutated patients., Results: MKRN3 mutations were identified in one sporadic and 13 familial cases. We identified five new heterozygous missense mutations predicted to be deleterious for protein function and two frameshift mutations, one new and the other recurrent, predicted to result in truncated proteins. Age at puberty onset varied very little among patients with MKRN3 mutations and puberty occurred earlier in these patients than in those without MKRN3 mutations (6.0 years (5.4-6.0) vs 7.0 years (6.0-7.0), P=0.01)., Conclusions: MKRN3 mutations are common in familial iCPP. MKRN3 is one of the gatekeepers of the postnatal activation of the gonadotropic axis., (© 2016 European Society of Endocrinology.)
