Short- and mid- term impact of tobacco smoking on donor renal function following living kidney donation at a tertiary referral hospital

Background: The negative impact of tobacco smoking on renal function has been widely studied. However, there is limited knowledge about the effect of smoking on pre-operative and post-operative renal function in living kidney donors. Objective: The objective of the study was to evaluate the short- and mid-term impact of smoking on donor renal function. Methods: This is a retrospective study of 308 patients who underwent living donor nephrectomy (LDN) at a tertiary referral hospital. We compared baseline characteristics as well as functional outcomes following LDN according to history of tobacco smoking. Estimated glomerular filtration rate (eGFR) was calculated with the modification of diet in renal disease equation in 6 time periods: pre-operative, 1 week, 1 month, 6 months, 12 months, and 24 months after surgery. We performed a Kaplan-Meier analysis for chronic kidney disease (CKD) outcome and binary logistic regression analysis to identify risk factors associated with CKD at 24 months of follow-up. Results: Among donors, 106 (34.4%) reported a smoking history before nephrectomy. Smoking donors had worse pre-operative eGFR than non-smokers (90 ± 26.3 mL/min/1.73m2 vs. 96 ± 27 mL/min/1.73 m2, respectively; p = 0.02) and lower eGFR at 1 week (p = 0.01), 1 month (p ≤ 0.01), 6 months (p = 0.01), and 12 months (p = 0.01) after LDN. Tobacco smoking (OR 3.35, p ≤ 0.01) and age ≥ 40 years at donation (OR 6.59, p ≤ 0.01) were associated with post-operative development of CKD at 24 months after LDN. Conclusions: Living kidney donors with a tobacco smoking history had an increased risk of developing chronic kidney disease following nephrectomy. Smoking-cessation strategies should be implemented.

Adolescer Saudável: screening and follow-up of risk at school / Adolescer Saudável: rastreio e seguimento do risco na escola

ABSTRACT Objective To characterize adolescents referred to medical consultation based on the screening tool "Perfil de Saúde do Utente Adolescente", and to compare to information gathered from a questionnaire and data assessed during the visit. Methods A retrospective and descriptive study, with analysis of the questionnaires filled out by adolescents and their respective medical records, in the period from January 2013 to June 2016.

Smoking and comorbidities are associated with COVID-19 severity and mortality in 565 patients treated in Turkey: a retrospective observational study

SUMMARY OBJECTIVE: We aimed to explore the prevalence of smoking rates and comorbidities and evaluate the relationship between them and disease severity and mortality in inpatients with COVID-19. METHODS: COVID-19 patients were divided into the following groups: clinic group, intensive care unit (ICU) group, survivors, and non-survivors. Non-COVID-19 patients were included as a control group. The groups were compared. RESULTS: There was no difference between patients with and without COVID-19 in terms of smoking, asthma, diabetes, dementia, coronary artery disease (CAD), hypertension, chronic renal failure and arrhythmia (p>0.05). Older age (Odds ratio (OR), 1.061; 95% confidence interval (CI): 1.041-1.082; p< 0.0001), chronic obstructive pulmonary disease (COPD) (OR, 2.775; 95% CI: 1.128-6.829; p=0.026) and CAD (OR, 2.696; 95% CI: 1.216-5.974; p=0.015) were significantly associated with ICU admission. Current smoking (OR, 5.101; 95% CI: 2.382-10.927; p<0.0001) and former smoking (OR, 3.789; 95% CI: 1.845-7.780; p<0.0001) were risk factors for ICU admission. Older age (OR; 1.082; 95% CI: 1.056-1.109; p<0.0001), COPD (OR, 3.213; 95% CI: 1.224-8.431; p=0.018), CAD (OR, 6.252; 95% CI: 2.171-18.004; p=0.001) and congestive heart failure (CHF) (OR, 5.917; 95% CI 1.069-32.258; p=0.042), were significantly associated with mortality. Current smoking (OR, 13.014; 95% CI: 5.058-33.480; p<0.0001) and former smoking (OR, 6.507; 95% CI 2.731-15.501; p<0.0001) were also risk factors for mortality. CONCLUSION: Smoking, older age, COPD, and CAD were risk factors for ICU admission and mortality in patients with COVID-19. CHF was not a risk factor for ICU admission; however, it was a risk factor for mortality.

RESUMO OBJETIVO: Buscamos explorar as taxas de prevalência de tabagismo e de comorbidades e avaliar a relação entre elas e a severidade e mortalidade da doença em pacientes hospitalizados com COVID-19. MÉTODOS: Pacientes com COVID-19 foram divididos nos seguintes grupos: grupo clínico, grupo da unidade de terapia intensiva (UTI), grupo de sobreviventes e não-sobreviventes. Pacientes sem COVID-19 foram incluídos em um grupo de controle. Os grupos foram comparados. RESULTADOS: Não houve diferença entre os pacientes com e sem COVID-19 em termos de tabagismo, asma, diabetes, demência, doença arterial coronariana (DAC), hipertensão arterial, insuficiência renal crônica e arritmia (p>0,05). Idade mais avançada (odds ratio (OR), 1,061; 95% de intervalo de confiança (IC): 1,041-1,082; p< 0,0001), doença pulmonar obstrutiva crônica (DPOC) (OR, 2,775; 95% IC: 1,128-6,829; p=0,026) e DAC (OR, 2,696; 95% IC: 1,216-5,974; p=0,015) estavam significativamente associados com a admissão na UTI. O tabagismo atual (OR, 5,101; 95% IC: 2,382-10,927; p < 0,0001) e tabagismo prévio (OR, 3,789; 95% IC: 1,845-7,780; p< 0,0001) foram fatores de risco para admissão na UTI. Idade mais avançada (OR; 1,082; 95% IC: 1,056-1,109;< 0,0001), DPOC (OR, 3,213; 95% IC: 1,224-8,431; p=0,018), DAC (OR, 6,252; 95% IC: 2,171-18,004; p=0,001) e insuficiência cardíaca congestiva (ICC) (OR, 5,917; 95% IC 1,069-32,258; p=0,042) estavam significativamente associados com mortalidade. O tabagismo atual (OR, 13,014; 95% IC: 5,058-33,480; p<0,0001) e o tabagismo prévio (OR, 6,507; 95% IC 2,731-15,501; p<0,0001) também foram fatores de risco para mortalidade. CONCLUSÃO: O tabagismo, a idade avançada, DPOC e DAC foram fatores de risco para admissão na UTI e mortalidade em pacientes com COVID-19. ICC não foi um fator de risco para admissão na UTI; no entanto, foi um fator de risco para mortalidade.

ERICA: smoking is associated with more severe asthma in Brazilian adolescents / ERICA: tabagismo está associado a asma mais grave em adolescentes brasileiros

Abstract Objective: To investigate the association between smoking and asthma, and possible associated factors in Brazilian adolescents. Methods: A cross-sectional, national, school-based study with adolescents aged 12-17 years, participants in the Study of Cardiovascular Risks in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes - ERICA). A total of 66,394 participants answered a self-administered questionnaire with questions about asthma, smoking, lifestyle and sociodemographic variables. Bivariate analysis between Current Asthma (CA) and Severe Asthma (SA) and the other study variables were performed using Chi-squared. Then, the crude and adjusted Prevalence Ratios (PR), and respective 95% Confidence Intervals (95% CI) of current asthma/severe asthma and smoking variables, corrected for sociodemographic and lifestyle variables, were estimated using generalized linear models with Poisson regression, logit link, and robust variance. Results: The prevalence of current asthma and severe asthma were significantly higher in adolescents who were exposed to: experimentation (current asthma: PR = 1.78, 95% CI: 1.51-2.09; severe asthma: PR = 2.01; 95% CI: 1.35-2.98); current smoking (current asthma: PR = 2.08, 95% CI: 1.65-2.64; severe asthma: PR = 2.29; 95% CI: 1.38-3.82); regular smoking (current asthma: PR = 2.25, 95% CI: 1.64-3.07; severe asthma: PR: 2.41; 95% CI: 1.23-4.73); and passive smoking (current asthma: PR = 1.47, 95% CI: 1.27-1.67; severe asthma: PR = 1.66; 95% CI: 1.19-2.32); these associations remained significant after adjustment. Conclusions: Asthma and smoking were significantly associated in Brazilian adolescents, regardless of the sociodemographic and lifestyle factors, notably in those with more severe disease.

Resumo: Objetivo: Investigar a associação entre asma, tabagismo e possíveis fatores associados em adolescentes brasileiros. Métodos: Estudo transversal, nacional, de base escolar, envolveu adolescentes com 12 a 17 anos, participantes do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA). Os 66.394 participantes responderam questionários autopreenchíveis com questões sobre asma, tabagismo, estilo de vida e dados sociodemográficos. Foram realizadas análises bivariadas entre asma ativa e asma grave e demais variáveis do estudo, com o uso de χ2. Em seguida, foram estimadas as razões de prevalência (RP) brutas e ajustadas e seus respectivos intervalos de confiança de 95% (IC 95%), entre asma ativa/asma grave e variáveis de tabagismo, corrigidas pelas variáveis sociodemográficas e de estilo de vida, através de modelos lineares generalizados com regressão de Poisson, função de ligação logarítmica e variância robusta. Resultados: A prevalência de asma ativa e asma grave foi significativamente mais elevada naqueles expostos a experimentação (asma ativa: RP = 1,78; IC 95%: 1,51-2,09; asma grave: RP = 2,01; IC 95%: 1,35-2,98); tabagismo atual (asma ativa: RP = 2,08; IC 95%: 1,65-2,64; asma grave: RP = 2,29; IC 95%: 1,38-3,82); tabagismo frequente (asma ativa: RP = 2,25; IC 95%: 1,64-3,07; AG = 2,41; IC 95%: 1,23-4,73) e tabagismo passivo (asma ativa: RP = 1,47; IC 95%: 1,27-1,67; asma grave: RP = 1,66; IC 95%: 1,19-2,32). As associações permaneceram significativas após ajuste. Conclusão: A asma e o tabagismo se associaram de modo significativo em adolescentes brasileiros independente de fatores sociodemográficos e estilo de vida, especialmente naqueles com doença mais grave.

Cervical arterial dissection: clinical characteristics in a neurology service in São Paulo, Brazil / Dissecção arterial cervical: características clínicas em um serviço de neurologia de São Paulo, Brasil

ABSTRACT Cervical arterial dissection accounts for only a small proportion of ischemic stroke but arouses scientific interest due to its wide clinical variability. Objective: This study aimed to evaluate its risk factors, outline its clinical characteristics, compare treatment with antiaggregation or anticoagulation, and explore the prognosis of patients with cervical arterial dissection. Methods: An observational, retrospective study using data from medical records on patients with cervical arterial dissection between January 2010 and August 2015. Results: The total number of patients was 41. The patients' ages ranged from 19 to 75 years, with an average of 44.5 years. The most common risk factor was smoking. Antiaggregation was used in the majority of patients (65.5%); 43% of all patients recanalized in six months, more frequently in patients who had received anticoagulation (p = 0.04). Conclusion: The presence of atherosclerotic disease is considered rare in patients with cervical arterial dissection; however, our study found a high frequency of hypertension, smoking and dyslipidemia. The choice of antithrombotic remains controversial and will depend on the judgment of the medical professional; the clinical results with anticoagulation or antiaggregation were similar but there was more recanalization in the group treated with anticoagulation; its course was favorable in both situations. The recurrence of cervical arterial dissection and stroke is considered a rare event and its course is favorable.

RESUMO As dissecções arterais cervicais correspondem somente a uma pequena proporção dos casos de acidente vascular cerebral (AVC) isquêmico, mas despertam interesse científico devido à sua alta variabilidade clínica. Objetivos: Este estudo destina-se a avaliar os fatores de risco, desfechos clínicos, comparar o tratamento com anticoagulação e antiagregação, e avaliar o prognóstico desses pacientes. Métodos: Estudo observacional, retrospectivo utilizando dados de prontuários de pacientes com dissecção arterial cervical entre os períodos de janeiro de 2010 e agosto de 2015. Resultados: O número de pacientes foi 41. A idade foi de 19 a 75 anos, com idade média de 44,5 anos. O fator de risco mais comum encontrado foi o tabagismo. Antiagregação foi utilizada na maioria dos pacientes (65,5%); 43% dos pacientes apresentaram recanalização em seis meses, sendo esta mais frequentemente observada nos pacientes que receberam anticoagulação (p = 0,04). Conclusão: A presença de doença aterosclerótica é considerada rara em pacientes com dissecção arterial cervical. Entretanto, nosso estudo encontrou alta frequência de hipertensão arterial, tabagismo e dislipidemia. A escolha pela terapia antitrombótica permanece controversa e dependerá do julgamento clínico do médico; os resultados clínicos com anticoagulação ou antiagregação foram similares, mas houve maior taxa de recanalização no grupo tratado com anticoagulação. A recorrência de dissecação arterial cervical e AVC foi considerada rara e o curso, favorável.

¿Existe asociación entre asma y adiposidad en la población adulta chilena? / Association between adiposity and asthma

Background: In people with asthma, adiposity is associated with more symptoms and less control of the disease whereas on those without asthma adiposity is associated with a higher risk of developing the disease. Aim: To investigate the association between asthma and adiposity markers in Chilean adults. Material and Methods: Data from 5,499 adults older than 15-years-old from the Chilean National Health Survey 20162017 were analyzed. Quintiles of body-mass index (BMI) and waist circumference (WC) were used as a proxy of adiposity. The association between asthma and quintiles of BMI and WC was determined by logistic regression. Results: A higher BMI and WC was associated with a higher odds for asthma. This trend remained significant even after adjusting the models for socio-demographic factors, physical activity and smoking (Odds Ratio [OR] BMI: 1.13 [95% confidence intervals (CI): 1.04; 1.22], p < 0.01 and OR WC: 1.15 [95% IC: 1.06; 1.25], p < 0.01). Conclusions: A higher BMI and WC were positively associated with asthma.

Resistant and refractory hypertension: two sides of the same disease? / Hipertensão resistente e refratária: duas faces de uma mesma doença?

Abstract Refractory hypertension (RfH) is an extreme phenotype of resistant hypertension (RH), being considered an uncontrolled blood pressure besides the use of 5 or more antihypertensive medications, including a long-acting thiazide diuretic and a mineralocorticoid antagonist. RH is common, with 10-20% of the general hypertensives, and its associated with renin angiotensin aldosterone system hyperactivity and excess fluid retention. RfH comprises 5-8% of the RH and seems to be influenced by increased sympathetic activity. RH patients are older and more obese than general hypertensives. It is strongly associated with diabetes, obstructive sleep apnea, and hyperaldosteronism status. RfH is more frequent in women, younger patients and Afro-americans compared to RFs. Both are associated with increased albuminuria, left ventricular hypertrophy, chronic kidney diseases, stroke, and cardiovascular diseases. The magnitude of the white-coat effect seems to be higher among RH patients. Intensification of diuretic therapy is indicated in RH, while in RfH, therapy failure imposes new treatment alternatives such as the use of sympatholytic therapies. In conclusion, both RH and RfH constitute challenges in clinical practice and should be addressed as distinct clinical entities by trained professionals who are capable to identify comorbidities and provide specific, diversified, and individualized treatment.

Resumo A Hipertensão Arterial Refratária (HARf) representa um fenótipo extremo da hipertensão arterial resistente (HAR), sendo considerada a falência ao tratamento apesar do uso de 5 ou mais classes de anti-hipertensivos, incluindo um diurético tiazídico de longa ação e um antagonista mineralocorticoide. A HAR é comum (10-20%) entre os hipertensos em geral, sendo decorrente de hiperatividade do Sistema Renina Angiotensina Aldosterona e retenção hidrossalina. Aqueles com HARf correspondem a 5-8% dos resistentes e parecem sofrer maior influência catecolaminérgica. Os resistentes tendem a ter maior idade, ao sobrepeso e à obesidade. Comorbidades incluem diabetes, apneia obstrutiva do sono e status de hiperaldosteronismo. Refratários são afro-americanos em maior proporção, mais jovens e, predominantemente, mulheres. Ambos são fortemente associados à elevada albuminúria, HVE, doenças cardio e cerebrovasculares, além da doença renal crônica. O fenômeno do jaleco branco parece ser mais evidente nos resistentes. Quanto ao tratamento, a intensificação da terapia diurética está indicada nos resistentes, enquanto na HARf, a falência à terapia impôs novas alternativas de tratamento ("simpaticolíticas"). Em conclusão, tanto a HAR quanto a HARf constituem-se desafios na prática clínica e devem ser abordadas como entidades clínicas distintas por profissionais especialistas que identifiquem comorbidades e venham a prover um tratamento específico, diversificado e individualizado.

Role of genetic susceptibility in nicotine addiction and chronic obstructive pulmonary disease

Abstract Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in developed countries. Although cigarette smoking is the major risk factor, only 10-20% of smokers develop COPD. The extent of cigarette smoking (pack-years and smoking duration) accounts for only 15% of the variation in lung function, indicating that differences in susceptibility to COPD must exist. We provide an overview of the complexity of nicotine addiction and COPD, with special attention to the involvement of genetic factors. The following aspects are discussed in the present article: (1) epidemiology in Mexico and (2) a review of the published literature on genetic association studies using the National Center for Biotechnology Information database of the United States as a search tool. COPD is unique among complex genetic diseases where an environmental risk factor is known and the level of exposure can be documented with some precision. The high morbidity and mortality associated with COPD and its chronic and progressive nature has prompted the use of molecular genetic studies to identify susceptibility factors for the disease. Biomedical research has a remarkable set of tools to aid in the discovery of genes and polymorphisms. We present a review of the most relevant genetic associations in nicotine addiction and COPD.

Small airway disease in COPD associated to biomass exposure

Abstract Chronic obstructive pulmonary disease (COPD) is a complex and heterogeneous entity that may result from different causative agents and risk factors and may follow diverse clinical courses, including COPD secondary to biomass smoke exposure. At present, this phenotype is becoming more important for two reasons: first, because at least almost half of the world's population is exposed to biomass smoke, and second, because the possibility of it being diagnosed is increasing. Biomass smoke exposure COPD affects primarily women and is related with insults to the airways occurred during early life. Although constituents of biomass smoke and tobacco smoke are similar, the physiopathological changes they induce differ depending not only on the chemical composition (related with the type of fuel used) but also on the particle size and the inhalation pattern. Evidence has shown that biomass smoke exposure affects the airway, predominantly the small airways causing anthracofibrosis and peribronchiolar fibrosis changes that will clinically translate into chronic bronchitis symptoms, with a high impact on the quality of life. In this review, we focus especially on the main epidemiological and clinical differences between COPD secondary to biomass exposure and COPD caused by tobacco exposure.

Prevalence and co-occurrence of modifiable risk factors in adults and older people / Prevalência e coocorrência de fatores de risco modificáveis em adultos e idosos

ABSTRACT OBJECTIVE To estimate the co-occurrence of the major risk factors for chronic diseases in adults (18-59 years old) and older people (≥ 60 years old) living in Brazilian state capitals and the Federal District. METHODS Cross-sectional study with population-based data from 35,448 adults and 18,726 older people collected in the Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (System of Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Survey - Vigitel) in 2015. The prevalence of each of the five risk factors (smoking, overweight, physical inactivity, alcohol and unhealthy diet) was estimated, as well as their co-occurrence for the different possible combinations, according to socioeconomic and health self-assessment variables. The independent associations were verified via multinomial logistic regression to obtain the estimates of the odds ratio (OR) and corresponding 95% confidence intervals. RESULTS At least two risk factors were present in 38.5% of the adults and 37.0% of the older participants. The male adults and older participants who did not have private health insurance and classified their health as average or poor/very poor were more likely to have two or more concurrent risk behaviors. The greater chance of co-occurrence of smoking and alcohol abuse in adults (adjusted OR = 3.52) and older people (adjusted OR = 2.94) stands out. CONCLUSIONS The subgroups with increased risk of developing multiple unhealthy behaviors and the most prevalent behaviors were identified. These findings are expected to contribute to the better targeting of health promotion and preventive care. It is worth noting that, for the adoption of healthy lifestyle habits, macro-social and inter-sectoral policies are more effective.

RESUMO OBJETIVO Estimar a coocorrência dos principais fatores de risco para doenças crônicas não transmissíveis em adultos (18 a 59 anos) e idosos (≥ 60 anos) residentes nas capitais dos estados brasileiros e Distrito Federal. MÉTODOS Estudo transversal de base populacional com dados de 35.448 adultos e 18.726 idosos coletados no Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel) em 2015. Estimaram-se as prevalências de cada um dos cinco fatores de risco (tabagismo, excesso de peso, inatividade física, uso de álcool e alimentação não saudável), assim como sua coocorrência para as diferentes combinações possíveis, segundo variáveis socioeconômicas e autoavaliação da saúde. As associações independentes foram verificadas por meio de regressão logística multinomial para obter as estimativas do odds ratio (OR) e respectivos intervalos de confiança de 95%. RESULTADOS Ao menos dois fatores de risco estavam presentes em 38,5% dos adultos e 37,0% dos idosos. Adultos e idosos do sexo masculino, que não possuíam plano de saúde privado e que avaliaram sua saúde como regular ou ruim/muito ruim apresentaram maiores chances de ter dois ou mais comportamentos de risco simultâneos. Destaca-se a maior chance de coocorrência de tabagismo e uso abusivo de álcool em adultos (OR ajustado = 3,52) e idosos (OR ajustado = 2,94). CONCLUSÕES Foram identificados subgrupos com maior risco de desenvolver múltiplos comportamentos não saudáveis e os comportamentos mais prevalentes. Almeja-se que esses resultados contribuam para o melhor direcionamento de ações de promoção de saúde e assistência preventiva. Destaca-se que, para a adoção de hábitos de vida saudáveis, as políticas macrossociais e intersetoriais são mais efetivas.

Prevalence of smoking and reasons for continuing to smoke: a population-based study / Prevalência de tabagismo e motivos para continuar a fumar: estudo de base populacional

ABSTRACT Objective: To investigate the prevalence of smoking and the reasons for continuing to smoke among adults in Brazil. Methods: This was a cross-sectional, population-based study including 1,054 individuals ≥ 40 years of age, residents of the city of Florianopolis, Brazil, of whom 183 were smokers. All of the smokers completed the University of São Paulo Reasons for Smoking Scale (USP-RSS). Depressive symptoms were evaluated with the Hospital Anxiety and Depression Scale, and spirometry was performed to screen for COPD. Results: Of the 183 smokers, 105 (57.4%) were female, 138 (75.4%) were White, and 125 (63.8%) were in a low economic class. The mean level of education among the smokers was 9.6 ± 6.1 years. The mean smoking history was 29 ± 15 pack-years, 59% of the men having a ≥ 30 pack-year smoking history. Approximately 20% of the smokers had COPD, and 29% had depressive symptoms, which were more common in the women. The USP-RSS scores were highest for the pleasure of smoking (PS), tension reduction (TR), and physical dependence (PD) domains (3.9 ± 1.1, 3.6 ± 1.2, and 3.5 ± 1.3, respectively). Scores for the PS, TR, and weight control (WC) domains were significantly higher in women. Smokers with a > 20 pack-year smoking history scored significantly higher on the PD, PS, automatism, and close association (CA) domains. Smoking history was associated with the PD, PS, TR, and CA domains. Depressive symptoms were associated with the PD, social smoking, and CA domains (p = 0.001; p = 0.01; p = 0.09, respectively). Female gender and a low level of education were associated with the PS domain (p = 0.04) and TR domain (p < 0.001). Conclusions: The prevalence of smoking in our sample was relatively high (17.4%). The USP-RSS domains PS, TR, and WC explain why individuals continue smoking, as do depressive symptoms.

Métodos: Estudo transversal de base populacional com 1.054 indivíduos com idade ≥ 40 anos residentes em Florianópolis (SC), dos quais 183 eram tabagistas. Todos os fumantes preencheram a Escala Razões para Fumar da Universidade de São Paulo (ERF-USP). Os sintomas de depressão foram avaliados por meio da Hospital Anxiety and Depression Scale, e a presença ou ausência de DPOC foi determinada por meio de espirometria. Resultados: Dos 183 fumantes, 105 (57,4%) eram do sexo feminino, 138 (75,4%) eram brancos e 125 (63,8%) pertenciam a uma classe econômica baixa. A média de escolaridade entre os fumantes foi de 9,6 ± 6,1 anos. A média de carga tabágica foi de 29 ± 15 anos-maço, e 59% dos homens apresentavam carga tabágica ≥ 30 anos-maço. Aproximadamente 20% dos fumantes apresentavam DPOC, e 29% apresentavam sintomas de depressão, mais comuns entre as mulheres. A pontuação obtida na ERF-USP foi maior nos domínios prazer de fumar (PF), redução da tensão (RT) e dependência física (DF): 3,9 ± 1,1; 3,6 ± 1,2 e 3,5 ± 1,3, respectivamente. A pontuação obtida nos domínios PF, RT e controle de peso (CP) foi significativamente maior entre as mulheres. Fumantes com carga tabágica > 20 anos-maço obtiveram pontuação significativamente maior nos domínios DF, PF, automatismo e associação estreita (AE). A carga tabágica relacionou-se com os domínios DF, PF, RT e AE. Sintomas de depressão relacionaram-se com os domínios DF, tabagismo social e AE (p = 0,001; p = 0,01; p = 0,09, respectivamente). Sexo feminino e baixa escolaridade relacionaram-se com os domínios PF (p = 0,04) e RT (p < 0,001). Conclusões: A prevalência de tabagismo em nossa amostra foi relativamente alta (17,4%). Os domínios PF, RT e CP da ERF-USP, bem como os sintomas de depressão, explicam por que os indivíduos continuam a fumar.

Agregação dos fatores de risco cardiovascular: álcool, fumo, excesso de peso e sono de curta duração em adolescentes do estudo ERICA / Aggregation of cardiovascular risk factors: alcohol, smoking, excess weight, and short sleep duration in adolescents in the ERICA study / Agregación de los factores de riesgo cardiovascular: alcohol, tabaco, exceso de peso y sueño de corta duración en adolescentes del estudio ERICA

Resumo: O objetivo foi analisar a agregação do consumo de álcool, tabaco, excesso de peso e sono curto em adolescentes brasileiros. Trata-se de estudo transversal, multicêntrico realizado com base em adolescentes participantes do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA). A amostra foi composta por adolescentes que responderam completamente aos questionários sobre sono, tabaco e uso de bebidas alcoólicas, além de terem realizado antropometria com medidas de peso e estatura aferidas. A agregação foi analisada comparando a prevalência observada com a esperada dos fatores de risco em todas as possibilidades de agrupamento, e seus intervalos de 95% de confiança. As análises foram realizadas no programa estatístico Stata 14, mediante uso do comando svy (survey) para dados de amostra complexa. São 73.624 adolescentes, 25,5% dos estudantes apresentam excesso de peso e 24,2% fazem uso de bebida alcoólica. A agregação dos quatro fatores de risco foi de O/E = 5,6. A prevalência de agregação dos três fatores foi maior naqueles com 15 a 17 anos (P = 4,8). Na análise de ORP (odds ratio de prevalência) da combinação de dois fatores de risco, observou-se que os fumantes têm 11,80 vezes mais chances de também beber quando comparados àqueles que não fumam e vice-versa, nas escolas privadas. Em relação à idade, adolescentes com 12 e 14 anos que fumam têm 15,46 vezes mais chances de também beber e vice-versa. Adolescentes estudados apresentam a presença dos quatro fatores de forma agregada e há relação significativa entre o tabaco e o consumo de álcool.

Abstract: This study aimed to analyze the aggregation of alcohol consumption, smoking, excess weight, and short sleep in Brazilian adolescents. This was a cross-sectional multicenter study conducted with teens participating in the Study of Cardiovascular Risk Factors in Adolescents (ERICA in Portuguese). The sample consisted of adolescents that answered the complete questionnaires on sleep, tobacco, and alcoholic beverages, in addition to having their weight and height measured. Aggregation was analyzed by comparing the observed and expected prevalence of risk factors in all possible groupings, with the respective 95% confidence intervals. Analyses were performed in Stata 14 using the svy (survey) command for complex sample data. The sample included 73,624 adolescents, of whom 25.5% had excess weight and 24.2% consumed alcoholic beverages. Aggregation of the four risk factors was O/E = 5.6. Aggregation of three factors was more prevalent in those 15 to 17 years of age (P = 4.8). In the POR (prevalence odds ratio) analysis of the combination of two risk factors, those that smoked showed 11.80 higher odds of also consuming alcohol, compared to those that did not smoke, and vice versa, in private schools. In relation to age, adolescents 12 to 14 years of age that smoked showed 15.46 times higher odds of also drinking, and vice and versa. Adolescents in the sample presented the aggregate presence of four risk factors, and there was a significant relationship between tobacco and alcohol consumption.

Resumen: El objetivo fue analizar la agregación del consumo de alcohol, tabaco, exceso de peso y sueño corto en adolescentes brasileños.

Occurrence and predictors of gingivitis and supragingival calculus in a population of Brazilian adults

Abstract: The aim of this study was to determine the occurrence of gingivitis and calculus and their predictors in a population of adults in Brazil. A representative sample of 758 adults from 35 to 59 years of age from Porto Alegre city was examined. A structured questionnaire was applied. The Gingival Bleeding Index and the presence of calculus were measured at 4 sites/tooth. Multivariable logistic models were fitted to determine the predictors for gingival bleeding at >20% of sites. Overall, 96.5% (95% confidence interval [CI]=95.1-98.0) of individuals had ≥ 1 bleeding site. The mean percentages of sites with gingivitis and calculus were 26.1% and 44.6%, respectively. The odds of gingivitis decreased by ∼45% for individuals ≥40 years old compared to younger adults. Individuals that never performed interproximal cleaning and non-whites had an approximately two times higher chance of gingivitis. Smokers had lower chances of gingivitis than never-smokers (odds ratio=0.40; 95% CI=0.24-0.68). Higher numbers of missing teeth were associated with higher chances of gingivitis. The percentage of calculus was significantly associated with skin color, education, proximal cleaning, smoking exposure, dental visits, and tooth loss. It can be concluded that the occurrence of gingivitis and calculus was high in this Brazilian population, and it was associated with age, skin color, education, self-reported proximal cleaning, smoking, dental care, and tooth loss.

Smoking and pulmonary tuberculosis treatment failure: a case-control study / Tabaquismo y fracaso del tratamiento de la tuberculosis pulmonar. Un estudio de casos y controles

ABSTRACT Objective: To determine the association between smoking and pulmonary tuberculosis treatment failure. Methods: This was a case-control study conducted at the Brazilian Institute for Tuberculosis Research in the city of Salvador, Brazil, between 2007 and 2015. We evaluated 284 patients treated for pulmonary tuberculosis, comparing 50 cases of treatment failure with 234 control cases in which the final outcome was cure. Results: Treatment failure was attributed to smoking and age rather than to gender, income, level of education, alcohol consumption, or marital status. Therefore, even after adjustment for age, the risk of treatment failure was 2.1 times (95% CI: 1.1-4.1) higher among the patients with a history of smoking. In addition, being over 50 years of age was found to increase the likelihood of treatment failure by 2.8 times (95% CI: 1.4-6.0). Conclusions: Smoking and aging are both associated with pulmonary tuberculosis treatment failure. Therefore, as part of a tuberculosis control program, health personnel should be prepared to offer strategies to promote smoking cessation and should be more careful with older patients.

RESUMEN Objetivo: Determinar la asociación entre el tabaquismo y el fracaso del tratamiento de la tuberculosis pulmonar. Metodología: Este es un estudio caso - control, realizado en el Instituto Brasilero para la Investigación de la Tuberculosis en Salvador, Brasil entre 2007 y 2015. Se compararon 50 casos de fracaso en el tratamiento con 234 controles de pacientes con diagnóstico de tuberculosis pulmonar y con resultado final de cura. Resultados: Se atribuyó el fracaso del tratamiento al tabaquismo y a la edad, y no al sexo, salario, escolaridad, consumo de alcohol o estado civil. Así, aun después del ajuste por edad, los pacientes con antecedentes de tabaquismo tienen 2,1 (IC95% 1,1-4,1) veces más chance de fracaso en el tratamiento de la tuberculosis. Además, tener una edad mayor de 50 años mostró que la posibilidad de fracaso aumenta 2,8 (IC95% 1,4-6,0) veces más. Conclusiones: El tabaquismo está relacionado con el fracaso del tratamiento de la tuberculosis pulmonar, así como también el envejecimiento. Por tal motivo, como parte del control de la tuberculosis, el personal de salud debe estar preparado para ofrecer estrategias que promuevan la cesación tabáquica y tener un mayor cuidado con pacientes de grupos etarios superiores.

Prevalência de fatores de risco cardiovascular na população de Vitória segundo dados do VIGITEL e da Pesquisa Nacional de Saúde de 2013 / Prevalence of cardiovascular risk factors in the population of Vitória according to data from VIGITEL and the National Health Interview Survey of 2013

RESUMO: Objetivo: Comparar a prevalência de fatores de risco cardiovascular na população de Vitória (ES) em pesquisa autorreferida por contato telefônico (VIGITEL) ou por exames clínicos e laboratoriais realizados na Pesquisa Nacional de Saúde (PNS). Método: Os inquéritos foram realizados na população adulta de Vitória (≥18anos). No VIGITEL foram entrevistados 1996 indivíduos (homens = 38%). Na PNS foi feita visita domiciliar seguida de exames clínicos e laboratoriais em 318 indivíduos (homens = 48%) selecionados em 20setores censitários da cidade. Nos dois inquéritos, as prevalências foram ajustadas para a estrutura populacional estimada para o ano de 2013. Os dados são fornecidos como porcentagens e intervalo de confiança de 95% (IC95%). Resultados: Foram encontradas prevalências similares no VIGITEL e na PNS, respectivamente, para tabagismo (8,2%; IC95% 6,7 - 9,7% versus 10,0; IC95% 6,4 - 13,6%) e hipertensão (24,8%; IC95% 22,6- 27,0% versus 27,2%; IC95% 21,8 - 32,5%). Houve diferença estatística (p < 0,01) entre o VIGITEL e a PNS, respectivamente, para as prevalências de obesidade (16,8%; IC95% 14,1 - 18,1% versus 25,7%; IC95% 20,4- 30,9%) e colesterol elevado (≥ 200mg/dL) no sangue (20,6%; IC95% 18,6 - 22,6% versus 42,3%; IC95% 36,9- 47,7%). A prevalência de diabetes também foi maior (p < 0,05) na PNS (6,7 versus 10,7%). Conclusão: A prevalência populacional de hipertensão e tabagismo foi estimada adequadamente no VIGITEL. Isso não ocorreu com a obesidade por provável viés de informação do peso corporal no VIGITEL. Os dados mostram a necessidade de melhorar a cobertura diagnóstica das dislipidemias em vista da importância do controle desse fator de risco na prevenção primária das doenças cardiovasculares.

ABSTRACT: Objective: To compare the prevalence of cardiovascular risk factors in the adult population of Vitória, Espírito Santo, Brazil, in two surveys conducted by telephone interview (VIGITEL) or by clinic and laboratory exams during the National Health Interview Survey (NHIS). Method: Data were collected from adults (≥ 18 years). In VIGITEL, 1,996 subjects (males = 38%) were interviewed. In NHIS, home visit followed by clinical and laboratory tests was made with 318 individuals (males = 48%) selected in 20 census tracts of the city. The prevalence of risk factors was adjusted to the estimated population of the city in 2013. Data are shown as prevalence and 95% confidence interval (95%CI). Results: Similar values of prevalence were found in VIGITEL and NHIS, respectively, for smoking (8.2%; 95%CI 6.7-9.7% vs 10.0; 95%CI 6.4 - 13.6%) and hypertension (24.8%; 95%CI 22.6 - 27.0% vs 27.2%; 95%CI 21.8 - 32.5%). Statistical differences between surveys (p < 0.01) were found for diabetes (6.7%; 95%CI 5.6 - 7.9% vs 10.7%; 95%CI 7.1 - 14.5%), obesity (16.8%; 95%CI 14.1 - 18.1% vs 25.7%; 95%CI 20.4 - 30.9%) and high cholesterol (≥ 200mg/dL) (20.6%; 95%CI 18.6- 22.6% vs 42.3%; 95%CI 36.9 - 47.7%). The prevalence of diabetes was also higher (p < 0.01) in NHIS (6.7 vs 10.7%). Conclusion: Prevalence of smoking and hypertension, but not obesity, was adequately detected in VIGITEL, because there might have been information bias related to body weight during telephone interviews. Datashow the necessity to improve the diagnosis of dyslipidemias in primary care services, as the control of this risk factor is of utmost importance to prevent cardiovascular diseases.

Impact of smoking on gingival inflammation in representative samples of three South American cities

Abstract The aim of this study was to investigate the impact of smoking on gingival inflammation in a representative sample of 1,650 adults from Santiago (Chile), Porto Alegre (Brazil), and Tucumán (Argentina). A questionnaire was administered to participants to gather demographic and behavioral characteristics, including smoking habits. The participants were clinically examined to obtain gingival index (GI), gingival bleeding index (GBI), visible plaque index (VPI), and calculus presence values. Gingival inflammation was defined as a mean GI > 0.5. Heavy smokers presented significantly lower levels of gingival inflammation, as reflected by both GI and GBI, than both light and moderate smokers, despite their having increased amounts of plaque and calculus. Being 50 years old or older [odds ratio (OR), 1.93], a VPI ≥ 30% (OR, 28.1), and self-reported diabetes (OR, 2.79) were positively associated with detection of gingival inflammation. In conclusion, the occurrence of clinically detectable gingival inflammation was lower in heavy smokers than light and moderate smokers. Older age, diabetes, and visible plaque emerged as risk indicators of gingivitis. Plaque and gingival indices are significantly associated regardless of the smoking status.

Update on the approach to smoking in patients with respiratory diseases / Atualização na abordagem do tabagismo em pacientes com doenças respiratórias

ABSTRACT Smoking is the leading cause of respiratory disease (RD). The harmful effects of smoking on the respiratory system begin in utero and influence immune responses throughout childhood and adult life. In comparison with "healthy" smokers, smokers with RD have peculiarities that can impede smoking cessation, such as a higher level of nicotine dependence; nicotine withdrawal; higher levels of exhaled carbon monoxide; low motivation and low self-efficacy; greater concern about weight gain; and a high prevalence of anxiety and depression. In addition, they require more intensive, prolonged treatment. It is always necessary to educate such individuals about the fact that quitting smoking is the only measure that will reduce the progression of RD and improve their quality of life, regardless of the duration and severity of the disease. Physicians should always offer smoking cessation treatment. Outpatient or inpatient smoking cessation treatment should be multidisciplinary, based on behavioral interventions and pharmacotherapy. It will thus be more effective and cost-effective, doubling the chances of success.

RESUMO O tabagismo é o maior responsável pelas doenças respiratórias (DR). Os efeitos nocivos do tabaco sobre o aparelho respiratório se iniciam ainda intraútero e influenciam as respostas imunológicas ao longo da infância e vida adulta. Os tabagistas com DR possuem peculiaridades que podem dificultar a cessação tabágica, tais como maior grau de dependência e de abstinência de nicotina; níveis mais elevados de monóxido de carbono exalado; motivação e autoeficácia baixas; maior preocupação com ganho ponderal; e elevada prevalência de ansiedade e depressão. Além disso, requerem tratamento mais intensivo e prolongado. É necessário esclarecer sempre o paciente sobre o fato de que parar de fumar será a única medida que irá reduzir a progressão das DR e melhorar sua qualidade de vida, independentemente do tempo e da gravidade da doença. Os médicos devem sempre oferecer o tratamento de cessação tabágica. O tratamento ambulatorial ou hospitalar deve ser multidisciplinar, baseado em intervenções comportamentais e farmacoterapia, sendo eficaz e custo-efetivo, dobrando as chances de sucesso.
