"Readiness to Change" Predicts Efficacy of Reduction among Smokers with Severe Mental Illness.

2018

<b><i>Aims:</i></b> Smoking cessation in subjects with a severe mental illness (SMI) is a challenging but attainable goal. Furthermore, the identification of variables involved in the quitting process is a highly relevant factor in clinical practice. This study aimed to analyze the influence of smokers’ motivation in smoking reduction and cessation and select the most suitable way of measuring motivation. <b><i>Methods:</i></b> This is a secondary analysis of a 9-month, multicenter trial examining a Multicomponent Smoking Cessation Program in 82 adult outpatients with SMI. At the end of the preparation stage, the smokers’ motivational level wa…

Cigarette Smoking Status at Diagnosis and Recurrence in Intermediate-risk Nonemuscle-invasive Bladder Carcinoma

2013

Objective To study the effect of smoking status at diagnosis on recurrence in intermediate-risk non–muscle-invasive bladder carcinoma treated by transurethral resection (TUR) of the bladder and early intravesical chemotherapy. Methods Tumor characteristics and smoking status were recorded in 395 patients entered in a randomized multicenter trial comparing 2 different schedules of early intravesical chemotherapy. All patients received intravesical epirubicin (80 mg/50 mL) within 6 hours after TUR, followed by 5 more weekly instillations with (arm B) or without (arm A) monthly instillations for 1 year. Smoking habit was investigated at diagnosis through a structured questionnaire. Multivariat…

Blue-yellow deficiencies in young moderate smokers.

2021

Purpose To evaluate whether tobacco affects color vision in young moderate smokers. Methods Chromatic mechanisms of 13 moderate smokers (10–20 cigarettes/day and at least 5 years smoking) and 17 non-smokers in the 18–35 age range were assessed with the Farnsworth-Munsell 100-hue (FM100h) test and short wavelength automated perimetry (SWAP). Results FM100h Total Error Scores (TES) were higher for smokers, and although differences were not significant (p = 0.14), a linear model with principal component analysis was able to explain 95% of the variance in TES and red-green partial error scores, though not in blue-yellow partial error scores (p = 0.07), using the number of years as smokers and t…

ERYTHROCYTE CATALASE ACTIVITY IN EVER-SMOKERS AND NO-SMOKERS HEALTHY SUBJECTS: INFLUENCE OF FLAVONOIDS (QUERCETIN AND LUTEOLIN)

2013

ERYTHROCYTE CATALASE ACTIVITY IN EVER-SMOKERS AND NO-SMOKERS HEALTHY SUBJECTS: INFLUENCE OF FLAVONOIDS(QUERCETIN AND LUTEOLIN) Background. Oxygen free radicals are highly reactive species that can cause cell damage including lipid peroxidation, enzyme inactivation and DNA damage. Inactivation and removal of highly reactive species depend by the antioxidant defence systems. The catalase (CAT) belongs to the primary antioxidant defence system of the cell which catalyses the decomposition of hydrogen peroxide to water and molecular oxygen. Flavonoids are a group of polyphenolic compounds with different chemical structure and properties. They are widely distributed in fruits, vegetables, nuts, …

Innate immunity but not NLRP3 inflammasome activation correlates with severity of stable COPD.

2014

Background In models of COPD, environmental stressors induce innate immune responses, inflammasome activation and inflammation. However, the interaction between these responses and their role in driving pulmonary inflammation in stable COPD is unknown. Objectives To investigate the activation of innate immunity and inflammasome pathways in the bronchial mucosa and bronchoalveolar lavage (BAL) of patients with stable COPD of different severity and control healthy smokers and non-smokers. Methods Innate immune mediators (interleukin (IL)-6, IL-7, IL-10, IL-27, IL-37, thymic stromal lymphopoietin (TSLP), interferon γ and their receptors, STAT1 and pSTAT1) and inflammasome components (NLRP3, NA…

Extracorporeal Shock Waves Increase Markers of Cellular Proliferation in Bronchial Epithelium and in Primary Bronchial Fibroblasts of COPD Patients

2020

Chronic obstructive pulmonary disease (COPD) is due to structural changes and narrowing of small airways and parenchymal destruction (loss of the alveolar attachment as a result of pulmonary emphysema), which all lead to airflow limitation. Extracorporeal shock waves (ESW) increase cell proliferation and differentiation of connective tissue fibroblasts. To date no studies are available on ESW treatment of human bronchial fibroblasts and epithelial cells from COPD and control subjects. We obtained primary bronchial fibroblasts from bronchial biopsies of 3 patients with mild/moderate COPD and 3 control smokers with normal lung function. 16HBE cells were also studied. Cells were treated with a…

COVID-19 Y SU REPERCUSIÓN EN LAS ADICCIONES

2021

espanolObjetivo. Indagar acerca de la literatura cientifica emergente a nivel internacional sobre la repercusion de la pandemia por COVID-19 en las adicciones. Metodologia. La base de datos Web of Science se utilizo para analizar la literatura cientifica sobre la pandemia por COVID-19 y la influencia que esta pueda tener en el ambito de las adicciones. Resultados. Se identificaron 320 documentos, de los cuales 38 cumplieron los criterios de inclusion. Sobresalieron tres problematicas: el consumo de tabaco, opioides y alcohol. Segun la literatura incipiente, entre los consumidores de opiaceos existe el riesgo de aumento de las sobredosis, asi como un empeoramiento del binomio estres-alcohol …

Catastrophic health expenditure: A comparative analysis of smoking and non-smoking households in China.

2020

Introduction Smoking is hazardous to health and places a heavy economic burden on individuals and their families. Clearly, smoking in China is prevalent since China is the largest consumer of tobacco in the world. Chinese smoking and nonsmoking households were compared in terms of the incidence and intensity of Catastrophic Health Expenditures (CHEs). The factors associated with catastrophic health expenditures were analyzed. Methods Data for this study were collected from two waves of panel data in 2011 and 2013 from the national China Health and Retirement Longitudinal Study (CHARLS). A total of 8073 households with at least one member aged above 45 were identified each year. Catastrophic…

Sociodemographic and behavioural correlates of lifetime number of sexual partners: findings from the English Longitudinal Study of Ageing.

2018

BackgroundNo current data are available on correlates of lifetime sexual partners at older ages. This study aimed to explore correlates of the lifetime number of sexual partners in a sample of older adults.MethodData were from 3054 men and 3867 women aged ≥50 years participating in the English Longitudinal Study of Ageing. Participants reported their lifetime number of sexual partners and a range of sociodemographic characteristics and health behaviours. Multivariable multinomial logistic regression was used to examine correlates of lifetime number of sexual partners, with analyses performed separately for men and women and weighted for non-response.ResultsYounger age, being separated/divor…
