K. Nihr Cancer ; Nutrition, Collaboration

Earlier diagnosis and more effective treatments mean that the estimated number of cancer survivors in the United Kingdom is expected to reach 4 million by 2030. However, there is an increasing realisation that excess body fatness (EBF) is likely to influence the quality of cancer survivorship and disease-free survival. For decades, the discussion of weight management in patients with cancer has been dominated by concerns about unintentional weight loss, low body weight and interventions to [...]

K. Nihr Cancer ; Nutrition, Collaboration

Growing data from epidemiological studies highlight the association between excess body fat and cancer incidence, but good indicative evidence demonstrates that intentional weight loss, as well as increasing physical activity, offers much promise as a cost-effective approach for reducing the cancer burden. However, clear gaps remain in our understanding of how changes in body fat or levels of physical activity are mechanistically linked to cancer, and the magnitude of their impact on cancer [...]

Menée aux Etats-Unis à partir des données d'une enquête réalisée en 3 vagues sur la période 2013-2016 et portant sur 1 096 jeunes fumeurs de cigarettes (âge : 18-24 ans), cette étude analyse l'association entre une utilisation de la cigarette électronique et les changements dans la fréquence ou l'intensité du tabagisme

The prevalence of electronic nicotine delivery systems (ENDS) use, including e-cigarettes, among US young adults (YAs) has raised questions about how these products may affect future tobacco and nicotine use among YAs. Given this prevalence and that young adulthood is a critical period for the establishment of tobacco and nicotine use, it is important to consider the association between ENDS use and cigarette smoking specifically in this age group.To examine whether ENDS use frequency or [...]

Electronic Nicotine Delivery Systems Use and Cigarette Smoking Frequency and Intensity Among Young Adult Smokers

Meghea, Cristian I.

The increased consumption of electronic nicotine delivery systems (ENDS), including e-cigarettes, among young adults in recent years raises the question of how ENDS may affect cigarette smoking and nicotine use among young adults. The study by Pearson et al investigates the association between ENDS use and changes in the frequency or intensity of cigarette smoking among US young adult ever smokers during a 1-year period. The study uses 3 yearly waves of Population Assessment of Tobacco and [...]

Anti-Tumor Effect of Vitamin D Combined with Calcium on Lung Cancer: A Systematic Review and Meta-Analysis

Sun, Kang ; Zuo, Minghao ; Zhang, Qin ; Wang, Keyi ; Huang, Dongdong ; Zhang, Honghe

Although many studies have demonstrated the impact of vitamin D and calcium on lung cancer, it remains the discrepancy for the effect of vitamin D and calcium on lung cancer. In this study, we aimed to verify the roles of vitamin D and calcium in the incidence and prognosis of lung cancer. A systematic literature search was performed by February 29, 2020. The relative risks (RRs) and hazard ratio (HRs) were pooled to evaluate the risk for the incidence and mortality of lung cancer. A total of [...]

Vitamin D and Lung Cancer; Association, Prevention, and Treatment

Wang, Weijie ; Hu, Wentao ; Xue, Shihang ; Chen, Qi ; Jiang, Yongsheng ; Zhang, Haina ; Zuo, Wei

Lung cancer is one of the common types of malignant disorders and the most prevalent cause of cancer-related mortality in the world. Although a wide range of approaches has been examined, strategies in prevention and treatment of lung cancer are still inadequate. Studies show that Vitamin D (VitD) is involved in various biological pathways and has been associated with the etiopathogenesis of several diseases, like cancers. In Vitro and In Vivo experiments have disclosed that VitD plays [...]
