Notes

Incidence regarding tobacco smoking and also association with various other poor lifestyle risks in the general population regarding Greece: Is caused by your EMENO review.
esearch should examine how differences in sociodemographic and smoking-related variables impact intervention outcomes and explore the role of sociocultural factors (e.g., acculturation and familism) as determinants of cessation.Alkali-extractable mycelial polysaccharide (Al-MPS) is a natural macromolecular polymer that has shown anti-hyperlipidemic and antitumor abilities. This study investigates the mechanism by which Al-MPS inhibits lipid metabolism and epithelial-mesenchymal transition (EMT) in breast cancer (BC). BC cells (MCF-7 and MDA-MB-231) were transfected and/or treated with Al-MPS. CCK-8, Transwell, and scratch assays were used to evaluate the tumorigenic behaviors of BC cells. The expression levels of SREBP1, E-cadherin, N-cadherin, Snail, vimentin, FASN, ACLY, and ACECS1 in BC cells were detected by Western blotting. Dual-luciferase reporter and RNA pull-down assays were performed to verify the binding between miR-215-5p and SREBP1 mRNA. Nude mice were injected with MDA-MB-231 cells and treated with Al-MPS. The changes in tumor volume and protein expression were monitored. miR-215-5p was downregulated and SREBP1 was upregulated in BC. Al-MPS increased miR-215-5p expression and inhibited SREBP1 expression, lipid metabolism, and EMT in BC. Inhibition of miR-215-5p or overexpression of SREBP1 promoted the tumorigenic behaviors of BC cells by stimulating lipid metabolism and counteracted the antitumor effect of Al-MPS. SREBP1 was a downstream target of miR-215-5p. In conclusion, Al-MPS inhibits lipid metabolism and EMT in BC via the miR-215-5p/SREBP1 axis. This study supports the application of polysaccharides in cancer treatment and the molecules regulated by Al-MPS may be used as biomarkers or therapeutic targets for BC.
Various risk factors have been associated with the risk of thyroid cancer in observational studies. However, the causality of the risk factors is not clear given the susceptibility of confounding and reverse causation.

A 2-sample Mendelian randomization approach was used to estimate the effect of potential risk factors on thyroid cancer risk.

Genetic instruments to proxy 55 risk factors were identified by genome-wide association studies (GWAS). Associations of these genetic variants with thyroid cancer risk were estimated in GWAS of the FinnGen Study (989 cases and 217 803 controls). A Bonferroni-corrected threshold of P = 9.09 × 10-4 was considered significant, and P < 0.05 was considered to be suggestive of an association.

Telomere length was significantly associated with increased thyroid cancer risk after correction for multiple testing (OR 4.68; 95% CI, 2.35-9.31; P = 1.12 × 10-5). Suggestive associations with increased risk were noted for waist-to-hip ratio (OR 1.85; 95% CI, 1.02-3.35; P = 0.042) and diastolic blood pressure (OR 1.60; 95% CI, 1.08-2.38; P = 0.019). Suggestive associations were noted between hemoglobin A1c (HbA1c) (OR 0.20; 95% CI, 0.05-0.82; P = 0.025) and decreased risk of thyroid cancer. Risk of thyroid cancer was not associated with sex hormones and reproduction, developmental and growth, lipids, diet and lifestyle, or inflammatory factors (All P > 0.05).

Our study identified several potential targets for primary prevention of thyroid cancer, including central obesity, diastolic blood pressure, HbA1c, and telomere length, which should inform public health policy.

Under healthy physiological conditions, this process is tightly coordinated and essential to maintain whole-body homeostasis. Selleckchem Tetrahydropiperine Not surprisingly, dysregulated mTOR signaling underpins several diseases with increasing incidence worldwide, including obesity, diabetes, and cancer. Consequently, there is significant clinical interest in developing therapeutic strategies that effectively target this pathway. The transition of mTOR inhibitors from the bench to bedside, however, has largely been marked with challenges and shortcomings, such as the development of therapy resistance and adverse side effects in patients. In this review, we discuss the current status of first-, second-, and third-generation mTOR inhibitors as a cancer therapy in both preclinical and clinical settings, with a particular emphasis on the mechanisms of drug resistance. We focus especially on the emerging role of diet as an important environmental determinant of therapy response, and posit a conceptual framework that links nutrient availability and whole-body metabolic states such as obesity with many of the previously defined processes that drive resistance to mTOR-targeted therapies. Given the role of mTOR as a central integrator of cell metabolism and function, we propose that modulating nutrient inputs through dietary interventions may influence the signaling dynamics of this pathway and compensatory nodes. In doing so, new opportunities for exploiting diet/drug synergies are highlighted that may unlock the therapeutic potential of mTOR inhibitors as a cancer treatment.
There remains inconclusive evidence on potential changes in smoking status and behaviours during the COVID-9 pandemic, especially in developing countries. This study explores the direction of changes in smoking status and behaviours after ten months of the COVID-19 pandemic in Indonesia as well as examining the association between economic shocks and changes in smoking behaviours.

Primary data were gathered through a phone survey targeting productive-age mobile-phone users in Indonesia (n=1,082). Descriptive analysis was employed to determine changes in smoking status and behaviours ten month into the pandemic, while logistic regression analysis was used to investigate how employment shocks, financial strain, COVID-19 related indicators, and demographic characteristics were associated with smoking behaviours of people who continue smoking.

Respondents experiencing changes in smoking status were dominated by people who persistently smoked during the pandemic, while those who quit, relapsed, and started sdeveloping countries, specifically Indonesia. The discovered patterns on smokers' reaction to an exogenous shock may provide evidence to support tobacco control policies in Indonesia.
This study is the first to determine the direction and analyse the factors of changes in smoking during the COVID-19 pandemic in Indonesia. This new understanding should help improve predicting the trends in smoking in future crises or pandemics in developing countries, specifically Indonesia. The discovered patterns on smokers' reaction to an exogenous shock may provide evidence to support tobacco control policies in Indonesia.
Race and geographic differences in the prevalence and predictors of hypertension in stroke survivors have been reported, but apparent treatment-resistant hypertension (aTRH) among stroke survivors by race (African ancestry vs. non-Hispanic Caucasians) and by geography (continental Africa vs. the United States) are under studied.

This is a cross-sectional study using ethically approved stroke registries from the University of Florida and the Kwame Nkrumah University of Science and Technology, Kumasi, Ghana. Univariate and multivariate regression was used to evaluate for differences in prevalence of aTRH and associations with clinical covariates.

Harmonized data were available for 3,365 stroke survivors of which 943 (28.0%) were indigenous Africans, 558 (16.6%) African Americans, and 1,864 (55.4%) non-Hispanic Caucasians with median ages (interquartile range) of 59 (49-68), 61 (55-72), and 70 (62-78) years, P < 0.0001. The overall frequency of aTRH was 18.5% (95% confidence interval [CI] 17.2%-19.8%) with 42.7% (95% CI 39.6%-46.0%) among indigenous Africans, 16.1% (95% CI 13.2%-19.5%) among African Americans, and 6.9% (95% CI 5.8%-8.2%) among non-Hispanic Caucasians, P < 0.0001. Five factors associated with aTRH age, adjusted odds ratio (95% CI) of 0.99 (0.98-0.99), female sex 0.70 (0.56-0.87), cigarette smoking 1.98 (1.36-2.90), intracerebral hemorrhage 1.98 (1.57-2.48), and Black race namely indigenous Africans 4.42 (3.41-5.73) and African Americans 2.44 (1.81-3.29).

Future studies are needed to investigate the contribution of socioeconomic disparities in the prevalence aTRH in those with African Ancestry to explore the long-term impact, and evaluate effective therapeutic interventions in this subpopulation.

We examined the relationship between current tobacco use and functionally-important respiratory symptoms.

Longitudinal cohort study of 16,295 US adults without COPD in Waves 2-3 (W2-3, 2014-16) of the Population Assessment of Tobacco and Health Study. Exposure─Ten mutually-exclusive categories of tobacco use including single product, multiple product, former, and never use (reference). Outcome─Seven questions assessing wheezing/cough were summed to create a respiratory symptom index; cut-offs of ≥2 and ≥3 were associated with functional limitations and poorer health. Multivariable regressions examined both cut-offs cross-sectionally and change over approximately 12 months, adjusting for confounders.

All tobacco use categories featuring cigarettes (>2/3's of users) were associated with higher risk (vs. never users) for functionally-important respiratory symptoms at W2; e.g., at symptom severity ≥3, risk ratio for exclusive cigarette use was 2.34 [95% CI, 1.92-2.85] and for worsening symptoms at W3 wasory symptoms and worsening of symptoms, regardless of other products used with them.Exclusive use of other tobacco products (e-cigarettes, cigars, smokeless, hookah) was largely not associated with functionally-important respiratory symptoms and risks associated with their use was significantly lower than for cigarettes. The association for e-cigarettes was greatly attenuated by adjustment for cigarette pack-years and sensitive to how symptoms were defined.
In response to SARS-CoV2 (COVID-19), school districts incorporated remote learning as a mitigation strategy. This study examines the association between classroom setting (i.e., on-campus versus remote) and e-cigarette susceptibility or ever use among a sample of Texas public middle school students.

Data from n=985 students enrolled in the CATCH My Breath E-Cigarette Prevention Program trial were collected in Spring 2021. Participants were 6 th grade students in urban Texas. E-cigarette use was examined using the "at-risk" definition described by FDA, indicating either (1) susceptible never user; or (2) experimental ever use. A multi-level, logistic regression models examined the association between classroom setting and e-cigarette susceptibility/ever use. Covariates included sex, race/ethnicity, academic achievement, household e-cigarette use, perceived school connectedness, and school-level economic status. Models account for nesting within school district. Analyses stratified by race/ethnicity were also conducted.
