Review
The incidence of tumors in the human digestive system is relatively high, including esophageal cancer, liver cancer, pancreatic cancer, gastric cancer and colorectal cancer. These malignancies arise from a complex interplay of environmental and genetic factors. Among them, long non‑coding RNAs (lncRNAs), which cannot be translated into proteins, serve an important role in the development, progression, migration and prognosis of tumors. Small nucleolar RNA host gene 16 (SNHG16) is a typical lncRNA, and its relationship with digestive system tumors has been widely explored. The prevailing hypothesis suggests that the principal molecular mechanism of SNHG16 in digestive system tumors involves it functioning as a competitive endogenous RNA that interacts with other proteins, regulates various genes and influences a downstream target molecule. The present review summarizes recent research on the relationship between SNHG16 and numerous types of digestive system cancer, encompassing its biological functions, underlying mechanisms and potential clinical implications. Furthermore, it outlines the association between SNHG16 expression and pertinent risk factors, such as smoking, infection and diet. The present review indicated the promise of SNHG16 as a potential biomarker and therapeutic target in human digestive system cancer.

INTRODUCTION AND OBJECTIVE
Smoking-free policies protect non-smokers from the negative effects of smoking, but many young adults still use products containing nicotine. The aim of this article is to analyze the factors that influence young people's attitudes towards the ban on smoking in public places.
MATERIAL AND METHODS
Data were obtained from a representative sample of young adults aged 13-15 from the Global Youth Tobacco Survey (GYTS) conducted in the Czech Republic, Lithuania, Romania, Slovakia and Slovenia. Logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs).
RESULTS
At least a quarter of the adolescents were exposed to cigarette smoking, about 40% have parents who smoke and over 50% declared that they have peers who smoke. A higher proportion of adolescents have knowledge about the harmful effects of second-hand smoking (62.6-71.9%), but at least one-fifth of young people are still exposed to the marketing of tobacco products. Compared with current smoking, those with never smoked were significantly associated with positive attitude toward to restricting smoking in all five analyzed countries, with an AOR= 4.74 (95% CI: 3.61-6.23), AOR=4.33 (95% CI: 2.32-8.07), AOR=2.85 (95% CI: 2.19-3.70) and AOR=2.45 (95% CI: 1.65-3.64), respectively. Gender, age, smoking, exposure to second-hand smoke, knowledge about the harmful effects of smoking, anti-smoking education, seeing people using tobacco and exposure to tobacco marketing, were significantly associated with the attitudes of young people towards restricting smoking in public places.
CONCLUSIONS
The study provides useful information on factors that should be taken into account when planning anti-smoking strategies so that young people are able to resist the pressure to use tobacco products.

Review
Endothelial cell dysfunction is a complex process involving various causes, early and late events, and subsequent consequences. This review provides an overview of each aspect and outlines therapeutic interventions targeting these stages. Causes of endothelial dysfunction encompass a spectrum of risk factors including hypertension, diabetes, smoking, obesity, inflammation, oxidative stress, and genetic predispositions. Early events such as endothelial activation, inflammatory response, and dysregulated vasomotor tone precede late events like oxidative stress, endothelial apoptosis, and microvascular rarefaction. The consequences include endothelial remodelling, neovascularization, organ dysfunction, and clinical manifestations, highlighting the diverse impacts across multiple systems. While depicted linearly, the progression of endothelial dysfunction is dynamic, influenced by various factors such as the underlying cause and affected vascular bed. Understanding these dynamics is crucial for tailoring therapeutic interventions, ranging from lifestyle modifications to targeted therapies, to address the underlying causes and effects effectively. Here we provide comprehensive understanding of endothelial cell dysfunction that is essential for developing strategies to mitigate the impact of this dysregulation on health and cardiovascular diseases progression.

JACC. Advances Jan 2024Post-traumatic stress disorder (PTSD) is associated with increased rates of incident ischemic heart disease (IHD) in women.
BACKGROUND
Post-traumatic stress disorder (PTSD) is associated with increased rates of incident ischemic heart disease (IHD) in women.
OBJECTIVES
The purpose of this study was to determine mechanisms of the PTSD-IHD association in women.
METHODS
In this retrospective longitudinal cohort study, data were obtained from electronic health records of all U.S. women veterans who were enrolled in Veterans Health Administration care from January 1, 2000 to December 31, 2017. Propensity score matching was used to match women with PTSD to women without PTSD on age, number of prior Veterans Health Administration visits, and presence of various traditional and nontraditional cardiovascular risk factors at index visit. Cox regression was used to model time until incident IHD diagnosis (ie, coronary artery disease, angina, or myocardial infarction) as a function of PTSD and potential mediating risk factors. Diagnoses of IHD, PTSD, and risk factors were defined by International Classification of Diseases-9th or -10th Revision, and/or Current Procedural Terminology codes.
RESULTS
PTSD was associated with elevated rates of developing each risk factor. Traditional risk factors (hypertension, hyperlipidemia, smoking, diabetes) accounted for 24.2% of the PTSD-IHD association, psychiatric risk factors (eg, depression, anxiety, substance use disorders) accounted for 33.8% of the association, and all 13 risk factors accounted for 48.5% of the association.
CONCLUSIONS
Traditional IHD risk factors explained a quarter of the PTSD-IHD association in women veterans, and over half of the risk of IHD associated with PTSD remained unexplained even when adjusting for a wide range of risk factors. To be actionable, factors underlying the remaining PTSD-IHD association warrant timely investigation.

Health Care Science Aug 2023We aimed to explore the associations of adherence to an overall healthy lifestyle with cardiometabolic diseases (CMDs) among schoolteachers in China.
BACKGROUND
We aimed to explore the associations of adherence to an overall healthy lifestyle with cardiometabolic diseases (CMDs) among schoolteachers in China.
METHODS
We conducted a cross-sectional analysis among 2983 teachers (aged 39.8 ± 9.3 years, 73.8% women) in Zhejiang Province, China. A healthy lifestyle score (0-7) was constructed based on seven low-risk factors: healthy diet, noncurrent smoking, noncurrent drinking, regular exercise, normal body mass index (BMI), adequate sleep duration, and limited sedentary behavior. CMDs included self-reported hyperlipidemia, hypertension, diabetes, coronary heart disease, and stroke. Multivariable-adjusted logistic regression models were used to evaluate the associations between healthy lifestyle and CMD.
RESULTS
A total of 493 (16.5%) participants had at least one CMD, with hyperlipidemia, hypertension, and diabetes being the three leading CMDs. Each point increment in a healthy lifestyle score was associated with 20% lower odds of having CMD (-trend < 0.001). Compared with 0-3 low-risk factors, the odds ratios (s) and 95% confidence intervals (s) were 0.66 (0.50-0.88) for 4 low-risk factors and 0.51 (0.39-0.67) for 5-7 low-risk factors. We observed independent associations for normal BMI ( = 0.50, 95% = 0.40-0.63), noncurrent drinking ( = 0.53, 95% = 0.36-0.77), and limited sedentary behavior ( = 0.77, 95% = 0.62-0.96) in relation to CMD. Healthy diet ( = 0.75, 95% = 0.55-1.01) exhibited marginally significant association with CMD.
CONCLUSIONS
Our findings suggest that adherence to an overall healthy lifestyle is associated with lower odds of CMD among schoolteachers.

Review
Cardiovascular disease (CVD) is the leading cause of morbidity and mortality worldwide. Over the past 50 years, there has been a substantial decline in the incidence of CVD and related mortality in high-income countries, largely due to the mitigation of modifiable risk factors such as smoking, hypertension, and diabetes. However, a significant burden of CVD remains in low- to middle-income countries, despite their lower prevalence of traditional risk factors; other environmental factors, particularly pollution, play a significant role in this attributable risk. Mounting evidence underscores a strong association between pollution and adverse health effects, including CVD. This article is part 1 of a 2-part state-of-the-art review and discusses air pollution and its adverse effects on CVD, highlighting pathophysiological mechanisms and methods to reduce air pollution and exposure to these pollutants.

Frontiers in Oncology 2024To evaluate the effectiveness of MRI-based radiomics models in distinguishing between Warthin tumors (WT) and misdiagnosed or ambiguous pleomorphic adenoma (PA).
PURPOSE
To evaluate the effectiveness of MRI-based radiomics models in distinguishing between Warthin tumors (WT) and misdiagnosed or ambiguous pleomorphic adenoma (PA).
METHODS
Data of patients with PA and WT from two centers were collected. MR images were used to extract radiomic features. The optimal radiomics model was found by running nine machine learning algorithms after feature reduction and selection. To create a clinical model, univariate logistic regression (LR) analysis and multivariate LR were used. The independent clinical predictors and radiomics were combined to create a nomogram. Two integrated models were constructed by the ensemble and stacking algorithms respectively based on the clinical model and the optimal radiomics model. The models' performance was evaluated using the area under the curve (AUC).
RESULTS
There were 149 patients included in all. Gender, age, and smoking of patients were independent clinical predictors. With the greatest average AUC (0.896) and accuracy (0.839) in validation groups, the LR model was the optimal radiomics model. In the average validation group, the radiomics model based on LR did not have a higher AUC (0.795) than the clinical model (AUC = 0.909). The nomogram (AUC = 0.953) outperformed the radiomics model in terms of discrimination performance. The nomogram in the average validation group had a highest AUC than the stacking model (0.914) or ensemble model (0.798).
CONCLUSION
Misdiagnosed or ambiguous PA and WT can be non-invasively distinguished using MRI-based radiomics models. The nomogram exhibited excellent and stable diagnostic performance. In daily work, it is necessary to combine with clinical parameters for distinguishing between PA and WT.

Background/aims Most countries have gone through lockdowns to varying degrees during the COVID-19 pandemic to reduce the spread of the disease. The successive pandemic waves have impacted the health system, imposing restrictions set by the government. This changed people's daily life routines and they felt more socially isolated, which in turn had an impact on their mental health. Some factors were linked to the severity and outcome of COVID-19 on patients. One of these factors was smoking. This study was carried out to investigate the prevalence and impact of lockdown on smoking habits, as well as the changes in attitudes, behavior, and the rate of consumption before and after the government restrictions in the general population of Saudi Arabia. Materials and methods The present cross-sectional study was conducted on a sample of 921 participants from the general population of Saudi Arabia. Data were collected via an online questionnaire. A structured self-response questionnaire was given to the participants after institutional research ethical approval was obtained for the study. Results A total of 921 participants from the smoker population of Saudi Arabia were included in the study. The majority of participants were male (72.9%), and more than half were aged between 18 and 34 years (53.7%). Single individuals had a higher prevalence of increased smoking and a lower rate of quitting compared to married individuals. Participants with higher education levels were more likely to continue smoking at the same rate. While 40.5% of participants reported no change in their smoking rate during the pandemic, 15.4% reported a decrease, 39.0% reported an increase, and 5.1% reported quitting smoking. Participants who reported feeling more stressed during the pandemic had a higher prevalence of increased smoking. The majority of participants believed that smoking increased the risk of COVID-19 infection. Conclusion The study highlights the need for targeted smoking cessation interventions and support services during the pandemic, considering demographic factors, living arrangements, and psychological impact. Efforts should be made to raise awareness about the negative health consequences of smoking during the pandemic and provide resources for stress management and alternative coping strategies. These findings have important implications for public health interventions and policies in Saudi Arabia.

Review
Heated tobacco products represent a novel category of tobacco products in which a tobacco consumable is heated to a temperature that releases nicotine from the tobacco leaf but not to a temperature sufficient to cause combustion. Heated tobacco products may therefore have the potential to be a less harmful alternative for adult smokers who would otherwise continue to smoke cigarettes, as their use should result in exposure to substantially fewer and lower levels of toxicants. This update represents a two-year extension to our previous narrative review, which covered peer-reviewed journal articles published up to August 31, 2021. The scientific evidence published between 2021 and 2023 continues to indicate that aerosols produced from heated tobacco products contain fewer and substantially lower levels of harmful and potentially harmful constituents and that these observed reductions consistently translate to reduced biological effects in both and toxicological studies. Biomarker and clinical data from studies in which product use is controlled within a clinical setting continue to suggest changes in levels of biomarkers of exposure, biomarkers of potential harm, and clinical endpoints indicating the potential for reduced harm with switching to exclusive use of heated tobacco products in adult smokers. Overall, the available peer-reviewed scientific evidence continues to indicate that heated tobacco products offer promise as a potentially less harmful alternative to cigarettes, and as such, the conclusions of our original narrative review remain valid.
