Abstract
Waterpipe use among Iranian adolescents has become a matter for concern. A descriptive, cross-sectional community-based survey was performed in 2010 to determine the prevalence of waterpipe use and associated factors among Iranian adolescents in Tehran, Islamic Republic of Iran. After multi-stage, random cluster sampling 1201 adolescents aged 15-18 years old responded to a questionnaire based on the Youth Risk Behavior Surveillance. The prevalence of current waterpipe smoking (at least once in the previous 30 days) was 28.0%, significantly higher among males (34.8%) than females (21.4%). A total of 45.1% of adolescents reported lifetime use (ever use) of waterpipes and 34.2% had ever shared a waterpipe. In multivariate logistic regression analysis the significant correlates of current waterpipe use for both males and females were having smokers among friends and family members, while for males, older age and educational failure were also risk factors.

Abstract
OBJECTIVE: Globally, waterpipe (WP) smoking is becoming a more prevalent form of tobacco consumption. Whilst research so far has demonstrated a significant link between WP use and a number of health outcomes, little is known of its association with heart disease. We examine in this study the association of WP smoking with angiographically confirmed coronary artery disease (CAD). METHODS: A total of 1210 patients, aged 40 years and over and free from smoking-associated illnesses or history of cardiovascular procedures, admitted for coronary angiography at four major hospitals in Lebanon, were included. The extent of CAD was summarized in two ways, firstly as diseased (>/= 50% and >/= 70% occlusion in at least one main coronary artery) versus non-diseased (entirely normal coronaries), and secondly, as CAD cumulative score based on Duke CAD Prognostic Index. A score of WP-years, capturing intensity and lifetime duration of exposure, was estimated for each individual. RESULTS: Lifetime exposure exceeding 40 WP-years was associated with a threefold significant increase in the odds of having severe stenosis (>/= 70%) compared to non-smokers (OR = 2.94, 95% CI 1.04-8.33) as well as with the CAD Index (beta = 7.835, p-value = 0.027), net of the effect of socio-demographic characteristics, health behaviors and co-morbidity. A dose-response relationship between WP-years and percent stenosis was also established. WP smoking status (never, past and current) did not associate with CAD. CONCLUSIONS: Cumulative exposure to WP smoking is significantly associated with severe CAD. There is a need to monitor WP use among cardiac patients and include this information in their medical charts in the same manner cigarettes smoking is documented. This is likely to increase awareness of the hazards of WP smoking and prompt physicians to target WP tobacco control by providing advice to their patients on WP smoking cessation.

Abstract
OBJECTIVES: The purpose of this paper is to use data collected in the 2001 and 2005 Lebanon Global Youth Tobacco Survey (GYTS) to monitor articles in the WHO Framework Convention on Tobacco Control (WHO FCTC). This information is necessary to enhance the capacity of the Ministry of Health and relevant organizations to design, implement, and evaluate tobacco control and prevention programs in Lebanon, especially among adolescents. METHODS: The GYTS is a school-based survey which uses a two-stage sample design to produce representative, independent, cross-sectional estimates. The GYTS was conducted in 2001 and 2005 in Lebanon to produce representative national estimates. Data in this report are limited to students aged 13-15 years. In total, 5035 students from 50 schools participated in 2001; and 3341 students from 50 schools participated in 2005. RESULTS: The data in this report show that, in 2005, 8.6% of the students currently smoked cigarettes, but 33.9% currently smoked narguileh. Half of current smokers wanted to stop smoking and 6 in 10 have tried to stop during the past year but have failed. In 2005, exposure to SHS at home (78.4%) and in public places (74.4%) was very high; while 85.2% thought smoking should be banned in public places. Nearly 9 in 10 students who usually buy their cigarettes in stores were not refused purchase because of their age. Overall, only half of the students in Lebanon reported that during the past school year they had been taught about the dangers of smoking. CONCLUSIONS: Data in this report can be used as baseline measures for future evaluation of the tobacco control programs implemented by the Ministry of Health with particular attention to youth. The key for the Lebanese parliament is to develop, endorse, implement and enforce these new tobacco control laws and use the data from GYTS to monitor progress toward achieving the goals of the WHO FCTC. One key component of tobacco control needs to be the monitoring of Narguileh use among youth, a new emergency.

Abstract
OBJECTIVES: Indonesia has the fifth highest rate of annual cigarette consumption per person of all countries worldwide. The Global Youth Tobacco Survey (GYTS) was developed to provide data on youth tobacco use to countries for their development of youth-based tobacco control programs. Data in this report can be used as baseline measures for future evaluation of the tobacco control program implemented by Indonesia's Ministry of Health. METHODS: The 2006 Indonesia GYTS is a school-based survey that included separate samples for Java and Sumatera, representing more than 84% of the population of Indonesia. Each sample used a two-stage cluster sample design that produced representative samples of students in secondary grades 1-3, which are associated with ages 13-15 years. RESULTS: This report shows that more than 1 in 10 students (12.6%) currently smoked cigarettes, with the prevalence among boys (24.5%) significantly higher than among girls (2.3%). Of the students who currently smoked, more than 7 in 10 (75.9%) reported that they desired to stop smoking now. Regarding secondhand smoke exposure, more than 6 in 10 students (64.2%) reported that they were exposed to smoke from other people in their home during the week before the survey. More than 9 in 10 students (92.9%) had seen a lot of advertisements for cigarettes on billboards during the past month and more than 8 in 10 (82.8%) had seen a lot of advertisements for cigarettes in newspapers or in magazines. CONCLUSIONS: Tobacco control in Indonesia will likely not move forward until the government evaluates and strengthens existing laws, considers passing new strong laws, and develops protocols for enforcing all laws. The Indonesian government also should strongly consider accession to the World Health Organization Framework Convention on Tobacco Control.

Abstract
OBJECTIVE: This study assessed the effects of pictorial health warning labels (HWLs) and a linked media campaign in Mexico. METHODS: Cross-sectional data were collected from a population-based sample of 1756 adult smokers, aged 18-55 years, during the initial implementation of pictorial HWLs, which some smokers had seen on cigarette packages while others had seen only the text-based HWLs. Exposure to the campaign and pictorial HWLs was assessed with aided recall methods, and other questions addressed attention and cognitive impact of HWLs, knowledge related to HWL and campaign content, and quit-related thoughts and behaviours. Logistic and linear regression models were estimated to determine associations between key outcomes and intervention exposure. RESULTS: In bivariate and multivariate adjusted models, recall of pictorial HWLs and of the campaign were positively associated with greater attention to and cognitive impact of HWLs, whereas only pictorial HWL exposure was associated with having refrained from smoking due to HWLs. Both recall of pictorial HWLs and of the campaign were independently associated with greater knowledge of secondhand smoke harms and toxic tobacco constituents. Smokers who recalled only the pictorial HWLs were more likely to try to quit than smokers who recalled neither the pictorial HWLs nor the campaign (17% vs 6%, p

Abstract
Biofilms formed by Candida albicans bloodstream isolates on catheters are an important clinical problem. Devising chemotherapeutic strategies to treat these in situ is an attractive option. We report here that liposomal amphotericin effectively kills C. albicans biofilms rapidly (12 h) and effectively (>90%) in a dose-dependent manner, whereas caspofungin displays an inverse concentration-dependent effect. This study has implications for considering the effective doses of antifungal agents used for catheter lock therapy.

Abstract
Vaginal infections caused by Candida krusei are a problem of extreme complexity due to the intrinsic resistance to azole drugs. The species Syngonanthus nitens (Bong.) Ruhland is a plant of the Eriocaulaceae family that has demonstrated promising antifungal activity. In phyto-formulation research, liquid crystal precursor mucoadhesive systems (LCPM) stand out as drug delivery systems for vaginal administration because they increase the activity and overcome the problems associated with plant-based medicines. Therefore, the objective of this study was to evaluate the potential of the methanolic extract of scapes of S. nitens (S. nitens extract [SNE]) and an SNE-loaded LCPM against C. krusei as prophylaxis for vulvovaginal candidiasis. LCPM formulation developed consisted of oleic acid as the oil phase (50% w/w), polyoxypropylene (5) polyoxyethylene (20) cetyl alcohol (40% w/w) as the surfactant and a polymeric dispersion containing 2.5% Carbopol((R)) 974P and 2.5% polycarbophil (10% w/w) as the aqueous phase. LCPM formulation developed was characterized using polarized light microscopy, rheological analysis, and in vitro mucoadhesive studies. Different strains of C. krusei, including one standard strain (American Type Culture Collection 6258) and three clinically isolated strains from the vaginal region (CKV1, 2, and 3), were used to determine the minimum inhibitory concentration, inhibition of biofilms, and time kill. The in vivo prophylaxis assay was performed using the standard strain (American Type Culture Collection 6258). The analyses of F by polarized light microscopy and rheology showed isotropy; however, the addition of 100% artificial vaginal mucus (F100) made it more viscous and anisotropic. Moreover, the mucoadhesive strength was modified, which makes F an excellent formulation for vaginal applications. SNE was active against all strains studied, with minimum inhibitory concentration values ranging from 125 to 62.5 microg/mL; after incorporating SNE into F (FE), these values decreased to 62.5 to 31.2 microg/mL, demonstrating that incorporation into the formulation potentiated the action of SNE. Additionally, the time kill assays showed that both forms of SNE were capable of controlling growth, thereby suggesting a possible fungistatic mechanism. Unloaded SNE was not active against C. krusei biofilms, but FE was active against a clinical strain (CKV2). In vivo analysis showed that FE was able to prevent the development of infection following 10 days of administration. We concluded that the formulation developed in this study was an important vehicle for the delivery of SNE based on the improved antifungal activity in all in vitro and in vivo analyses. Furthermore, the extract incorporated into the system may serve as an important prophylactic agent against vaginal infections caused by C. krusei.

Abstract
OBJECTIVE: This study examines little cigar and cigarillo (LCC) adult user characteristics, perceived addictiveness, use and importance of flavors, intentions to continue use, and reasons for use to inform prevention efforts and regulatory policy. METHODS: Data come from the 2014 Tobacco Products and Risk Perceptions Survey of a national probability sample of 5717 US adults, conducted online, June-November, 2014. The analytic sample consisted of 141 current LCC users. RESULTS: Current LCC smokers were more likely to be male, younger, black or Hispanic, lower SES, current cigarette smokers, and to report poorer health than non-smokers. Perceived addictiveness was low overall, with 73.6% considering themselves "not at all" addicted, although female LCC users and dual users of cigarettes were more likely to consider themselves addicted to LCCs. Use of flavored LCCs was widespread. Flavors were cited as important reasons for use, especially among younger users, as were favorable comparisons with affordability and burn time of cigarettes. CONCLUSIONS: Most LCC users do not perceive themselves addicted to LCCs. Users report being influenced most by flavorings and affordability, indicating that appropriate regulations and education to improve health perceptions could help reduce use of these harmful products.

Abstract
Cassava beer, or chicha, is typically consumed daily by the indigenous Shuar people of the Ecuadorian Amazon. This traditional beverage made from cassava tuber (Manihot esculenta) is thought to improve nutritional quality and flavor while extending shelf life in a tropical climate. Bacteria responsible for chicha fermentation could be a source of microbes for the human microbiome, but little is known regarding the microbiology of chicha. We investigated bacterial community composition of chicha batches using Illumina high-throughput sequencing. Fermented chicha samples were collected from seven Shuar households in two neighboring villages in the Morona-Santiago region of Ecuador, and the composition of the bacterial communities within each chicha sample was determined by sequencing a region of the 16S ribosomal gene. Members of the genus Lactobacillus dominated all samples. Significantly greater phylogenetic similarity was observed among chicha samples taken within a village than those from different villages. Community composition varied among chicha samples, even those separated by short geographic distances, suggesting that ecological and/or evolutionary processes, including human-mediated factors, may be responsible for creating locally distinct ferments. Our results add to evidence from other fermentation systems suggesting that traditional fermentation may be a form of domestication, providing endemic beneficial inocula for consumers, but additional research is needed to identify the mechanisms and extent of microbial dispersal.
