Early-onset depressive disorders predict the use of addictive substances in adolescence: a prospective study of adolescent Finnish twins

2008

Aims  To explore the developmental relationships between early-onset depressive disorders and later use of addictive substances. Design, setting and participants  A sample of 1545 adolescent twins was drawn from a prospective, longitudinal study of Finnish adolescent twins with baseline assessments at age 14 years and follow-up at age 17.5 years. Measurements  At baseline, DSM-IV diagnoses were assessed with a professionally administered adolescent version of Semi-Structured Assessment for Genetics of Alcoholism (C-SSAGA-A). At follow-up, substance use outcomes were assessed via self-reported questionnaire. Findings  Early-onset depressive disorders predicted daily smoking [odds ratio (OR) …

Smoking Status and Severity of Ischemic Stroke. A Population-Based Study

2013

We aimed to investigate the impact of smoking status on clinical severity in patients with ischemic stroke event (IS). Patients were prospectively identified among residents of the city of Dijon, France (ca. 151,000 inhabitants), using a population-based registry, between 2006 and 2011. Demographic and clinical data were recorded. The initial clinical severity was quantified by the means of the National Institutes of Health Stroke Scale (NIHSS). Multivariable ordinal logistic regression was used to assess the effect of smoking status on severity. Among the 1,056 recorded patients with IS, data about smoking status were available for 973 (92.1%), of whom 658 (67.3%) were non-smokers, 187 (19…

Second-hand smoke exposure in 4-year-old children in Spain: Sources, associated factors and urinary cotinine

2016

Introduction Second-hand smoke exposure (SHS) in children remains as a major pollution problem, with important consequences for children's health. This study aimed to identify the sources of exposure to SHS among 4-year-old children, comparing self-reports to a urinary biomarker of exposure, and characterize the most important variables related to SHS exposure in this population. Methods 4-year-old children's exposure to SHS was assessed by a parental-reported questionnaire and by urinary cotinine (UC) measurements in 1757 participants from 4 different areas of the Spanish INMA (INfancia y Medio Ambiente – Environment and Childhood) Project. The questionnaire about SHS included information …

Permanence of Modifications in Oral Microcirculation in Ex-Smokers.

2019

Background: The aim of this study was to assess the long-term effects of smoking and to investigate the permanence of this damage to the oral microcirculation. Material/Methods: We recruited 75 patients and divided them into 3 groups: group 1 was composed of 25 healthy non-smokers, group 2 was composed of 25 healthy current smokers, and group 3 was composed of 25 healthy ex-smokers. Video-capillaroscopic examination was performed on all patients. The video-capillaroscopic investigation was performed on patients in sitting position, always with the same light source, at the same room temperature (23°C), in the morning, with the same operator (GAS), and was repeated many times for every area …

Electrochemical Quantification of H2O2 Released by Airway Cells Growing in Different Culture Media

2022

Quantification of oxidative stress is a challenging task that can help in monitoring chronic inflammatory respiratory airway diseases. Different studies can be found in the literature regarding the development of electrochemical sensors for H2O2 in cell culture medium to quantify oxidative stress. However, there are very limited data regarding the impact of the cell culture medium on the electrochemical quantification of H2O2. In this work, we studied the effect of different media (RPMI, MEM, DMEM, Ham’s F12 and BEGM/DMEM) on the electrochemical quantification of H2O2. The used electrode is based on reduced graphene oxide (rGO) and gold nanoparticles (AuNPs) and was obtained by co-electrode…

Microbial communities and novel taxa in « Continental Smokers » of northern Greece

2017

Analogously to the ocean-bottom black/white smokers, “continental smokers” have recently been defined as sites of mantle degassing through continental crust. The goal of this research, carried out within the Deep Carbon Observatory Community, is to investigate the role of deeplysourced fluids in niche ecosystem differentiation in European continental smokers. A 16S rRNA gene survey of microbial communities was carried out on 11 geothermal manifestations of northern Greece, all showing a distinct contribution of mantle fluids (R/Ra up to 1.2) that allow to classify them as continental smokers. The selected sites cover a wide range of temperatures (15-77 °C), pH (6.11-8.46), Eh (-289 – 40 mV)…

Neuropathological Alterations after Smoke Inhalation Injury, with and without Skin Burn

2020

More than 23,000 smoke inhalation injuries are reported in the United States each year. While the pathophysiology of smoke inhalation-induced lung injury is well studied, little is known about the acute effects of smoke inhalation on the central nervous system (CNS). Tragic events, such as those of the nightclub fire in Brazil in 2013, suggest that neurological complications occur following smoke inhalation injury, with the most commonly reported symptoms being a persistent headache, memory loss, and paresthesia. Additionally, one case report described that smoke inhalation alone was associated with progressive cognitive and psychiatric impairments, lasting for years after the initial injur…

Fumador, exfumador y COVID-19: la nicotina no protege contra el SARS-CoV-2

2021

Queremos agradecer a Moril et al.1 el interés en nuestro trabajo, pues nos permite reflexionar sobre el tema. La proteína Spike del SARS-CoV-2 es la responsable de facilitar su entrada a las células humanas, requiriendo cebado por la proteasa TMPRSS2 que permite la fusión de las membranas viral y celular2. El receptor utilizado por la proteína Spike es la enzima convertidora de angiotensina 2 (ACE2)2, que se expresa en diferentes estirpes celulares, además de en el pulmón; existiendo, a nivel pulmonar, un gradiente de expresión de ACE2 (mayor expresión en vías respiratorias superiores [epitelio nasal] y menor en los neumocitos alveolares)2. Se sugiere que una mayor expresión de ACE2 podría …
