Reliability of a decision-tree model in predicting occupational lead poisoning in a group of highly exposed workers

2016

Objective This study aimed to provide the toxicological profile of some lead-exposed workers and obtain a predictive model for lead poisoning. Methods Data regarding external and absorbed exposure were collected from 585 subjects employed in ten metallurgical production departments. Airborne lead concentration, blood lead level (BLL), cumulative blood lead index (CBLI), urine delta-aminolevulinic acid (DALA), age, workplace/section, exposure period, and whether reported lead poisoning as occupational disease were examined using ANOVA, and, post-ANOVA, Pearson correlation matrix, PCA (principal component analysis), decision-tree modeling, and logistic modeling. Results BLL was less sensitive…

The Association between Lead and Attention-Deficit/Hyperactivity Disorder: A Systematic Review.

2019

The etiology of Attention-Deficit/Hyperactivity Disorder (ADHD) is complex and multifactorial. Although the development of ADHD symptoms remains to be elucidated, in recent years, epigenetic processes have emerged as candidate mechanisms. Lead is one of the most dangerous environmental pollutants, and it is suspected to be associated with ADHD. The aim of the present study was to review the epidemiological literature currently available on the relation between lead exposure and the diagnosis of ADHD. The PubMed and EMBASE databases were searched from 1 July 2018 up to 31 July 2018. The authors included observational studies (cohort, case–control and cross-sectional studies) published in Eng…

Functional Data Analysis for ECG Recordings of Paroxysmal Atrial Fibrillation Patients Before and After Pulmonary Vein Isolation

2018

Pulmonary vein isolation is the cornestone of current ablation techniques for patients with paroxysmal atrial fibrillation in order avoid recurrences of the arrhythmia and maintain sinus rhythm. This study aimed to analyse the existence of significant variations in surface ECG after pulmonary vein isolation by means of functional data analysis. 12 consecutive unselected patients suffering from paroxysmal atrial fibrillation who underwent catheter ablation were included in the study. Each patient was monitored in sinus rhythm before and after catheter ablation. P-waves of bipolar lead II were delineated. Functional data were fitted from these segments and the first and second derivatives eva…

Stressing the Importance of Adult Immunization: Suggestions for How to Change the Paradigm

2019

From 24 to 26 May 2017, the European Interdisciplinary Council on Ageing (EICA) and the European Union Geriatric Medicine Society (EUGMS) brought together a group of key opinion leaders and stakeholders from the healthcare field, for a conference entitled “Changing the Paradigm: Stressing the Importance of Adult Immunization”. The specific objectives of this meeting were to review vaccine-preventable diseases (VPDs) and vaccine performance in older adults and analyse the impact of the adult vaccination campaigns currently being implemented in Europe. The meeting aimed to improve our understanding of the challenge that vaccine hesitancy or scepticism represents, and how existing barriers to …
