Smoking Fewer Than 5 Cigarettes a Day Damages Your Lungs Almost as Much as Smoking a Whole Pack, Study Says

Health officials have long argued there’s no safe amount of smoking—but, even still, many people assume a cigarette here and there doesn’t hurt. A new study published in the Lancet Respiratory Medicine puts that notion to rest: It found smoking just a handful of cigarettes per day causes lung damage similar to smoking more than a pack per day. The study examined the smoking habits and health of more than 25,000 Americans ages 17 to 93. At baseline, each person told the researchers how much they smoked (as well as general information about their health, demographics and lifestyle) and had a spirometry exam, which assesses lung function by measuring how much air can be exhaled in a second, as well as how much air the lungs can push out in total after taking a deep breath. Participants were then tracked for up to 20 years, during which time they had at least one more spirometry test to assess changes in lung health. Lung function naturally declines with age, but smoking is known to accelerate the process, putting smokers at risk of chronic obstructive pulmonary disease and other respiratory conditions. And as the researchers demonstrate in the new study, nearly any amount of smoking seems to kickstart that effect. When the study began, about 10,000 of the study participants had never smoked, while 7,000 had quit; 5,800 had vacillated between quitting and smoking; and 2,500 currently smoked. Over time, the researchers found that both former and current smokers...

Abstract Introduction: Few investigations have related objective assessments of indoor air pollutants to respiratory health in farmers, in spite of the many rural environmental hazards to which they are exposed. Chemical air pollution has been particularly neglected. Objective: We investigated the relationships of indoor exposure to particulate matter (PM) and volatile organic compounds (VOCs) to respiratory health in farmers. Methods: Nineteen VOCs (5 families) and PM (from ultrafine to total suspended particles (TSP)) were objectively assessed in dwellings and workplaces in 109 French farmers du...

Authors: Kaszuba M, Śliwka A, Piliński R, Kościelniak J, Maga P, Bochenek G, Nowobilski R Abstract The comorbidity of peripheral arterial disease (PAD) and chronic obstructive pulmonary disease (COPD) is obvious from a clinical point of view, especially as smoking is an important risk factor for both. Another factor connecting these two clinical conditions is chronic inflammation, which plays a crucial role in their pathophysiology. The aim of this study was to present the prevalence of COPD in patients with PAD, as well as the prevalence of PAD in COPD patients confirmed in all patients by two reliable methods:...

Authors: Okada Y, Hashimoto N, Iwano S, Kawaguchi K, Fukui T, Sakamoto K, Wakai K, Yokoi K, Hasegawa Y Abstract Although the lower limit of normal (LLN) of FEV1/FVC detects at-risk patients for postoperative outcomes among Japanese chronic obstructive pulmonary disease (COPD) patients with resected lung cancer, there was a lack of a Japanese reference equation to calculate the LLN of FEV1/FVC. Renewed Japanese spirometric reference variables might enable us to verify clinical impact of the LLN of FEV1/FVC among the Japanese population. To evaluate the clinical impact of the LLN of FEV1/FVC by using this renewed ref...

Conclusion: This case highlights the need to include paradoxical response to SABAs in the differential of a patient with poorly controlled asthma. It also provides an example of successful treatment of a pediatric patient with a class of medications previously reserved for adults with chronic obstructive pulmonary disease.

Franssen, Horst Olschewski, Mitja Lainscak, Michael Böhm, Luigi Tavazzi, Stephan RosenkranzAbstractHeart failure (HF) and chronic obstructive pulmonary disease (COPD) coincide in a significant number of patients. Recent population-based registries suggest that spirometry is largely underused in patients with HF to diagnose comorbid COPD and that patients with COPD frequently do not receive the recommended beta-blocker (BB) treatment. This state-of-the-art review summarizes: 1) current challenges in the impl...

Abstract BACKGROUND: Prediction of future lung function will enable the identification of individuals at high risk of developing chronic obstructive pulmonary disease (COPD), but the trajectory of lung function decline greatly varies among individuals. We developed and validated an individualized prediction model of lung function trajectory and risk of airflow limitation in the general population. METHODS: Data were obtained from the Framingham Offspring Cohort, which included 4,167 participants ≥20 years of age and had ≥2 valid spirometry assessments. The primary outcome was pre-bronchodilator forced e...

Normal spirometry is often used to preclude airway disease in individuals with unspecific respiratory symptoms. We tested the hypothesis that chronic respiratory symptoms are associated with respiratory hospitalisations and death in individuals with normal spirometry without known airway disease. We included 108 246 randomly chosen individuals aged 20–100 years from a Danish population-based cohort study. Normal spirometry was defined as a pre-bronchodilator forced expiratory volume in 1 s/forced vital capacity ratio ≥0.70. Chronic respiratory symptoms included dyspnoea, chronic mucus hypersecretion, whe...

Conclusions/Implications for Practice: Our findings confirmed a deterioration in pulmonary function in smokers who did not perform moderate or vigorous PA. The level of PA performed was positively related to pulmonary function in smokers, whereas in nonsmokers, improvements were only significant in LA–CA.
