The Association between Point-of-Sale Advertising Bans and Youth Experimental Smoking: Findings from the Global Youth Tobacco Survey (GYTS)

Background and Objectives: while existing research has demonstrated a positive association between exposure to point-of-sale (POS) tobacco advertising and youth smoking, there is limited evidence on the relationship between POS advertising restrictions and experimental smoking among youth. This study aims to fill this research gap by analyzing the association between POS advertising bans and youths'' experimental smoking. Methods: Global Youth Tobacco Surveys from 130 countries during 2007–2011 were linked to the WHO “MPOWER” tobacco control policy measures to analyze the association between POS advertising bans (a dichotomous measure of the existence of such bans) and experimental smoking using weighted logistic regressions. All analyses were clustered at the country level and controlled for age, parents'' smoking status, GDP per capita, and country-level tobacco control scores in monitoring tobacco use, protecting people from smoke, offering help to quit, warning about the dangers of tobacco, enforcing promotion/advertising bans, and raising taxes on tobacco. Results: The results suggest that a POS advertising ban is significantly associated with reduced experimental smoking among youth (OR = 0.63, p < 0.01), and that this association is seen for both genders (boys OR = 0.74, p < 0.1; girls OR = 0.52, p < 0.001). Conclusions: POS advertising bans are significantly associated with reduced experimental smoking among youth. Adopting POS advertising bans has the potential to reduce tobacco use among their youth in countries currently without such bans.

Therapeutic effects of bone marrow-derived mesenchymal stem cells on pulmonary impact injury complicated with endotoxemia in rats

Previous studies have demonstrated that acute lung injury (ALI) is associated with significant mortality and so far no effective pharmacotherapy is shown to reverse the natural progression. This study aims to investigate whether the transplantation of bone marrow derived mesenchymal stem cells (MSCs) might restore damaged pulmonary function and tissue structure in ALI. By using a sublethal chest impact injury plus endotoxemia model, MSCs were intravenously transplanted into the injured rats 2 h after trauma. The blood samples were obtained for determination of blood gas. Bronchoalveolar lavage fluid (BALF) was collected for analysis of inflammatory cell count and cytokine (TNF-α, IL-1β, IL-6 and IL-10) levels. The left lower lobes of the lungs, nearby the impact zone, were collected for SRY gene analysis and histological examination and scoring. After engraftment of MSCs, the number of inflammatory cells in BALF was decreased. Meanwhile, the secretions of pro-inflammatory TNF-α and IL-6 were alleviated, while the secretion of anti-inflammatory IL-10 was elevated. Engraftment of MSCs improved the pulmonary gas exchanges, alleviated the lung injury, and reduced the rats' mortality. These results suggested that the MSCs based measures might be a promising strategy in trauma and endotoxemia induced ALI treatment.
