Identification and Estimation of Causal Effects Using a Negative Control Exposure in Time-series Studies with Applications to Environmental Epidemiology.
Abstract The initial aim of environmental epidemiology is to estimate the causal effects of environmental exposures on health outcomes. However, due to lack of enough covariates in most environmental datasets, current methods without enough adjustments for confounders inevitably lead to residual confounding. We propose a Negative Control Exposure based on Time-series Studies (NCE-TS) model to effectively eliminate unobserved confounders using a post-outcome exposure as a negative control exposure. We show that the causal effect is identifiable and can be estimated by the NCE-TS for continuous and categorical outco...

Cardiotoxicity of Use of Sequential Aromatase Inhibitors in Women With Breast Cancer
AbstractThe association between use of aromatase inhibitors (AIs) and cardiovascular outcomes is controversial. While some observational studies have assessed the cardiovascular safety of AIs as upfront treatments, their cardiotoxicity as sequential treatments with tamoxifen remains unknown. Thus, we conducted a population-based cohort study using data from the United Kingdom Clinical Practice Research Datalink linked to the Hospital Episode Statistics and Office for National Statistics databases. We employed a prevalent new-user design to propensity-score match, in a 1:2 ratio, patients switching from tamoxifen to AIs wit...

Vital Signs: Estimated Proportion of Adult Health Problems Attributable to Adverse Childhood Experiences and Implications for Prevention - 25 States, 2015-2017.
CONCLUSIONS AND IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Efforts that prevent adverse childhood experiences could also potentially prevent adult chronic conditions, depression, health risk behaviors, and negative socioeconomic outcomes. States can use comprehensive public health approaches derived from the best available evidence to prevent childhood adversity before it begins. By creating the conditions for healthy communities and focusing on primary prevention, it is possible to reduce risk for adverse childhood experiences while also mitigating consequences for those already affected by these experiences.

Potentially Excess Deaths from the Five Leading Causes of Death in Metropolitan and Nonmetropolitan Counties - United States, 2010-2017.
This report enhances the geographic detail by using the six levels of the 2013 National Center for Health Statistics (NCHS) urban-rural classification scheme for counties and extending estimates of potentially excess deaths by annual percent change (APC) and for additional years (2010-2017). Trends were tested both with linear and quadratic terms. PERIOD COVERED: 2010-2017. DESCRIPTION OF SYSTEM: Mortality data for U.S. residents from the National Vital Statistics System were used to calculate potentially excess deaths from the five leading causes of death among persons aged <80 years. CDC's NCHS urban-rural c...

Workplace Secondhand Tobacco Smoke Exposure Among U.S. Nonsmoking Workers, 2015.
Abstract Secondhand tobacco smoke (SHS) exposure contributes to ill health and disease, including heart disease, lung cancer, and stroke (1). Although cigarette smoking has declined among U.S. workers, workplace exposure to SHS remains high, particularly among workers in certain industries, such as construction (2,3). Implementation of smoke-free laws has proven to be beneficial in reducing SHS exposure in general (1). CDC analyzed data from the 2015 National Health Interview Survey (NHIS) Occupational Health Supplement to assess the prevalence of self-reported workplace SHS exposure among nonsmoking workers by sm...

Cancer Survivorship and Subclinical Myocardial Damage.
Abstract The rate of cardiovascular disease among cancer survivors is higher than in the general population. This difference is due to traditional CVD risk factors and also to the cardiotoxicity of cancer treatment. In a population-based cohort study of 3,512 men and women who were free of CVD at visit 5, Florido et al. evaluated the association of cancer survivorship with subclinical myocardial damage, as assessed by elevated high-sensitivity cardiac Troponin T (hs-cTnT). Cancer survivors had significantly higher odds of elevated hs-cTnT (odds ratio [OR] = 1.26, 95% confidence interval [CI] 1.03, 1.53). Results w...

Quantification of biological age as a determinant of age-related diseases in the Rotterdam Study: a structural equation modeling approach
AbstractChronological age alone is not a sufficient measure of the true physiological state of the body. The aims of the present study were to: (1) quantify biological age based on a physiological biomarker composite model; (2) and evaluate its association with death and age-related disease onset in the setting of an elderly population. Using structural equation modeling we computed biological age for 1699 individuals recruited from the first and second waves of the Rotterdam study. The algorithm included nine physiological parameters (c-reactive protein, creatinine, albumin, total cholesterol, cytomegalovirus optical dens...

Exposure to Secondhand Smoke Among Nonsmokers - United States, 1988-2014.
Abstract Exposure to secondhand smoke from burning tobacco products can cause sudden infant death syndrome, respiratory infections, ear infections, and asthma attacks in infants and children, and coronary heart disease, stroke, and lung cancer in adult nonsmokers (1). There is no risk-free level of secondhand smoke exposure (2). CDC analyzed questionnaire and laboratory data from the National Health and Nutrition Examination Survey (NHANES) to assess patterns of secondhand smoke exposure among U.S. nonsmokers. The prevalence of secondhand smoke exposure among U.S. nonsmokers declined substantially during 1988-2014...

Multimorbidity and Comorbidity are now separate MESH headings
Nicholson et  al. in a commentary point out that confusion continues within clinical epidemiology articles and elsewhere as to how to reliably distinguish between ‘comorbidity’ and ‘multimorbidity’. Although differentiated in a paper by van der Akker (AK was an author) [1], only now in January 2018 has MeSH designated definitions and a different classification term for multimorbidity, distinct from comorbidity. Nicholson et al. re-emphasize that this is more than a semantic difference. While both terms focus on the occurrence of multiple chronic conditions within the same individual, the term ‘ ‘comorbidityâ€...

Tobacco Product Use Among Adults - United States, 2017.
Abstract Cigarette smoking harms nearly every organ of the body and causes adverse health consequences, including heart disease, stroke, and multiple types of cancer (1). Although cigarette smoking among U.S. adults has declined considerably, tobacco products have evolved in recent years to include various combustible, noncombustible, and electronic products (1,2). To assess recent national estimates of tobacco product use among U.S. adults aged ≥18 years, CDC, the Food and Drug Administration (FDA), and the National Institutes of Health's National Cancer Institute analyzed data from the 2017 National Health Int...
