Cigarette Smoking and Incident Stroke in Blacks of the Jackson Heart Study

Blacks are disproportionately affected by stroke compared with whites; however, less is known about the relationship between stroke and cigarette smoking in blacks. Therefore, we evaluated the relationship between cigarette smoking and all incident stroke in the JHS (Jackson Heart Study).. JHS participants without a history of stroke (n=4410) were classified by self‐reported baseline smoking status into current, past (smoked at least 400 cigarettes/life), or … Continue reading Cigarette Smoking and Incident Stroke in Blacks of the Jackson Heart Study

Dose-Response Association of Low-Intensity and Nondaily Smoking With Mortality in the United States

An increasing proportion of US smokers smoke at low intensity and not every day. Some nondaily smokers have always had this pattern, whereas others previously smoked daily. The effect of reducing the level of smoking from daily to nondaily smoking and the dose response at low smoking levels are poorly understood.. ..Among 505 500 participants (aged 18-103 years), approximately 47 000 deaths occurred. The median number of … Continue reading Dose-Response Association of Low-Intensity and Nondaily Smoking With Mortality in the United States

Cigarette #smoke exposure and inflammatory signaling increase the expression of the #SARS-CoV-2 receptor ACE2 in the respiratory tract

Abstract The factors mediating fatal SARS-CoV-2 infections are poorly understood. Here, we show that cigarette smoke causes a dose-dependent upregulation of Angiotensin Converting Enzyme 2 (ACE2), the SARS-CoV-2 receptor, in rodent and human lungs. Using single-cell sequencing data, we demonstrate that ACE2 is expressed in a subset of secretory cells in the respiratory tract. Chronic smoke exposure triggers the expansion of this cell population and … Continue reading Cigarette #smoke exposure and inflammatory signaling increase the expression of the #SARS-CoV-2 receptor ACE2 in the respiratory tract

Effects of changes in #smoking status on blood pressure among adult males and females in Indonesia: a 15-year population-based cohort study

The continuing rise of smoking behaviours will inevitably lead to a further increase in hypertension prevalence. However, limited research has examined the impacts of changes in smoking status on blood pressure (BP). We sought to assess correlations between increases or decreases of males’ and females’ cigarette consumption on systolic blood pressure (SBP), diastolic blood pressure (DBP) and pulse pressure (PP), and to investigate the relationship … Continue reading Effects of changes in #smoking status on blood pressure among adult males and females in Indonesia: a 15-year population-based cohort study

Association of #Cigarette Smoking With Antineutrophil Cytoplasmic Antibody–Associated #Vasculitis

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic small vessel vasculitis characterized by circulating ANCAs targeting proteinase 3 (PR3) or myeloperoxidase (MPO) and associated with excess morbidity and mortality. Myeloperoxidase-ANCA–positive AAV and PR3-ANCA–positive AAV are increasingly recognized to have differences in genetic risk, pathogenesis, and response to treatment. Risk factors for AAV, including cigarette smoking, are poorly understood.. ..Overall, 473 cases were matched with … Continue reading Association of #Cigarette Smoking With Antineutrophil Cytoplasmic Antibody–Associated #Vasculitis

Association of Healthy #Lifestyle With Years Lived Without Major Chronic Diseases

..Four baseline lifestyle factors (smoking, body mass index, physical activity, and alcohol consumption) were each allocated a score based on risk status: optimal (2 points), intermediate (1 point), or poor (0 points) resulting in an aggregated lifestyle score ranging from 0 (worst) to 8 (best). Sixteen lifestyle profiles were constructed from combinations of these risk factors. Main Outcomes and Measures The number of years between … Continue reading Association of Healthy #Lifestyle With Years Lived Without Major Chronic Diseases

Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study

There has been limited evidence for the association between chronic obstructive pulmonary disease (COPD) and the incidence of lung cancer among never smokers. We aimed to estimate the risk of lung cancer incidence in never smokers with COPD, and to compare it with the risk associated with smoking. This cohort study involved 338 548 subjects, 40 to 84 years of age with no history of lung … Continue reading Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study

Human transport of thirdhand tobacco #smoke: A prominent source of hazardous air pollutants into indoor nonsmoking environments

The contamination of indoor nonsmoking environments with thirdhand smoke (THS) is an important, poorly understood public health concern. Real-time THS off-gassing from smokers into a nonsmoking movie theater was observed with online and offline high-resolution mass spectrometry. Prominent emission events of THS tracers (e.g., 2,5-dimethylfuran, 2-methylfuran, and acetonitrile) and other tobacco-related volatile organic compounds (VOCs) coincided with the arrival of certain moviegoers and left residual … Continue reading Human transport of thirdhand tobacco #smoke: A prominent source of hazardous air pollutants into indoor nonsmoking environments

#Tobacco smoking and health-related quality of life among university students: Mediating effect of #depression

The aim of this study was to assess the association between cigarette smoking and health-related quality of life (HRQoL) among students in two different universities, and the potential mediating effect of depression. ..In both populations, after adjustment for socio-demographic, behavioral and health factors, smoking was associated with poorer Mental Composite Score (MCS) and Physical Composite Score (PCS)… After additional adjustment for BDI score, the observed … Continue reading #Tobacco smoking and health-related quality of life among university students: Mediating effect of #depression

Healthy #lifestyle and life #expectancy free of cancer, cardiovascular disease, and type 2 diabetes: prospective cohort study

..Five low risk lifestyle factors: never smoking, body mass index 18.5-24.9, moderate to vigorous physical activity (≥30 minutes/day), moderate alcohol intake (women: 5-15 g/day; men 5-30 g/day), and a higher diet quality score (upper 40%). .. The life expectancy free of diabetes, cardiovascular diseases, and cancer at age 50 was 23.7 years (95% confidence interval 22.6 to 24.7) for women who adopted no low risk … Continue reading Healthy #lifestyle and life #expectancy free of cancer, cardiovascular disease, and type 2 diabetes: prospective cohort study

Clustering of #lifestyle risk factors for non-communicable diseases in 304,779 #adolescents from 89 countries: A global perspective

The precursors of non-communicable diseases (NCDs) are often manifested during childhood and adolescence with little knowledge about co-occurrence of their related lifestyle risk factors. .. ..Adolescents aged 16–17 years, compared to those aged 11–13 years, had higher odds (OR 1.33; 95% CI 1.31–1.36) of reporting ≥3 risk factors. Risk factors clustered in multiple combinations and differed by sex. The clustering of physical inactivity and low … Continue reading Clustering of #lifestyle risk factors for non-communicable diseases in 304,779 #adolescents from 89 countries: A global perspective

Cardiovascular Effects of Switching From Tobacco #Cigarettes to Electronic Cigarettes

E-cigarette (EC) use is increasing exponentially worldwide. The early cardiovascular effects of switching from tobacco cigarettes (TC) to EC in chronic smokers is unknown. Meta-analysis of flow-mediated dilation (FMD) studies indicate 13% lower pooled, adjusted relative risks of cardiovascular events with every 1% improvement in FMD. ..The authors conducted a prospective, randomized control trial with a parallel nonrandomized preference cohort and blinded endpoint of smokers … Continue reading Cardiovascular Effects of Switching From Tobacco #Cigarettes to Electronic Cigarettes
