Periodontal disease, progressing from gingivitis to periodontitis, affects the majority of the world population. Its pathogenesis is related to a complex interaction between environmental, microbial, genetic and other host factors, tobacco smoking being the most important environmental risk factor. Conflicting results are reported in the literature regarding the effects of smoking habits on cytogenetic damage in exfoliated oral cells. We report herein the results of a study evaluating, for the first time, the frequency of micronucleated and binucleated cells in the gingival epithelium. There was no significant elevation of these cytogenetic end-points in 43 subjects as related to smoking habits (never-smokers, ex-smokers, and current smokers) and periodontal disease (mild, moderate, or severe forms of gingivitis and periodontitis). Therefore, the overall data emerging from the present study do not support the evidence for an association between smoking habits, periodontal disease and genotoxic damage in gingival epithelial cells.

Marginal ulcers are a common complication following Roux-en-Y bypass surgeries with an approximate incidence of 4.6%. The pathophysiology is complex and risk factors include smoking, nonsteroidal anti-inflammatory drugs (NSAIDs) use, Helicobacter pylori infection, and a larger pouch size.

China has implemented the "tiered medical services" policy since 2015, while there is a paucity of data evaluating the the current status of chronic obstructive pulmonary disease (COPD) management under the system. Characteristics and treatments from 11,905 COPD patients in 88 hospitals across different tiers in China were included and analyzed. We assessed the statistical significance of differences by one way analysis of variance (ANOVA) for continuous variables and with the chi-squared test for categorical variables.

We sought to determine whether clinical, imaging or laboratory features in patients hospitalized for CAP in whom PCR is positive for a respiratory virus enable exclusion of bacterial coinfection so that antibiotics can be withheld.
Methods: For this prospective study, we selected patients in whom an etiologic diagnosis was likely to be reached, namely those who provided a high-quality sputum sample at or shortly after admission, and in whom PCR was done to test for a respiratory virus.

Experiencing a traumatic event may lead to Posttraumatic Stress Disorder (PTSD), including symptoms such as flashbacks and hyperarousal. Individuals suffering from PTSD are at increased risk of cardiovascular disease (CVD), but it is unclear why. This study assesses shared genetic liability and potential causal pathways between PTSD and CVD.

Background: Tobacco advertisements or promotions (TAPs) can increase smoking susceptibility, especially among adolescents.China has made great progress in reducing TAPs, but has not yet achieved a total ban.This study estimated exposure to TAPs and smoking susceptibility and their changes from 2013-14 to 2021 among Chinese adolescents and examined their association.
