Kissidougou is one of the four Guinea prefectures (the others are Macenta, Gueckedou, and Conakry) where Ebola was first reported in West Africa in March 2014, and the mid-December increase was the largest documented by any prefecture in Guinea in a single week since the beginning of the epidemic. The Guinea Ministry of Health requested assistance from CDC and the World Health Organization to investigate the local outbreak, identify and isolate persons with suspected Ebola, assess transmission chains, and implement control measures. The investigation found that 85 confirmed Ebola cases were linked to one traditional funeral ceremony, including 62 (73%) cases reported during December 15-21. No additional cases related to this funeral ceremony were reported after January 10, 2015. After the outbreak was identified, rapid implementation of interventions limited additional Ebola virus transmission. Improved training for prompt reporting of cases, investigation, and contact tracing, and community acceptance of safe burial methods can reduce the risk for Ebola transmission in rural communities.

METHODS: Participants were young adults aged 18 to 25 who smoked at least one cigarette in the previous month (Study 1, N=1987 and Study 2, N=570) or smoked 3 or more days each week and used Facebook 4 or more days per week (Study 3, N=79). We examined both past-month e-cigarette use and ever use of e-cigarettes to quit conventional cigarettes. RESULTS: Prevalence of past-month use of e-cigarettes was higher in each subsequent study: Study 1 (6%), Study 2 (19%), and Study 3 (41%). In multivariate analyses, significant correlates of past-month e-cigarette use were identified for Study 1 (male sex OR=2.1, p=.03; past-year quit attempt OR=1.6, p=.03) and Study 2 (male sex, OR=1.7, p=.03; younger age OR=0.88, p=.05), but not Study 3. In multivariate analyses, significant correlates of ever use of e-cigarette to quit conventional cigarettes were identified for Study 1 (education, OR=1.2, p=.02; smoking within 30min of waking, OR=2.8, p=.02; past year quit attempt OR=4.1, p=.02), and Study 3 (desire to quit smoking, OR=1.3, p=.02), but not Study 2. CONCLUSIONS: E-cigarette use is increasingly common among young adults, particularly men. E-cigarette use for quitting conventional cigarettes appears more common among those more nicotine dependent and interested in quitting.

A solid-phase extraction (SPE) purification strategy, including three parallel procedures, was developed depending on sample type, and satisfactory purification performances were achieved for all selected CHMs. The limits of detection ranged from 0.12 to 1.08 mug kg(-1) for the analyzed PAHs. The average recoveries were in the range of 65.9 % to 100.8 %, except for naphthalene (43.8 %-75.9 %), and the relative standard deviations were =12.8 %. The proposed method was successfully applied to the analysis of PAHs in 24 CHMs including five roots, three stems, four flowers, two fruits, four seeds, three leaves, and three barks. In the samples analyzed, all 16 PAHs are present. Their sum ranges from 21.1 to 2236.3 mug kg(-1). The entire procedure was shown to be effective and conveniently fast, and may serve as an alternative screening protocol for the determination of PAHs in CHMs. Descriptors Links Book Title Database Publisher Data Source Authors Cui,Z., Ge,N., Zhang,A., Liu,Y., Zhang,J., Cao,Y.

This study evaluated the likely impact of nine GWLs proposed by the US Food and Drug Administration on (1) African American and (2) Hispanic smokers, who disproportionately bear the burden of tobacco-related illness, and (3) low education smokers, who have higher smoking rates. METHODS: Data were collected online from current smokers randomly assigned to see GWLs (treatment) or the current text-only warning labels (control). Participants were stratified by age (18-25; 26+) in each of four groups: general population (n = 1246), African Americans (n = 1200), Hispanics (n = 1200), and low education (n = 1790). We tested the effectiveness of GWLs compared to text-only warning labels using eight outcomes that are predictive of quitting intentions or behaviors including negative emotion, intentions to hold back from smoking, intentions to engage in avoidance behaviors, and intentions to quit. RESULTS: Across all outcomes, GWLs were significantly more effective than text-only warning labels more often than expected by chance. Results suggested that African Americans, Hispanics and smokers with low education did not differ from the general population of smokers in their reactions to any of the nine individual GWLs. CONCLUSIONS: The nine GWLs were similarly effective for disadvantaged sub-populations and the general population of smokers. Implementation of GWLs is therefore unlikely to reduce or exacerbate existing tobacco-related health disparities, but will most likely uniformly increase intentions and behaviors predictive of smoking cessation.

At first, OPPs were ultrasonically leached from soil samples by using methanol. After centrifugation, the separated methanol was diluted to 50 mL with double-distillated water and passed through the C18 SPE cartridge. OPPs were eluted with 1 mL acetonitrile. Thus, 1 mL acetonitrile extract (disperser solvent) and 10 microL 1-undecanol (extraction solvent) were added to 5 mL double-distilled water and a DSLLME technique was applied. The variables of interest in the USL-SPE-DSLLME method were optimized with the aid of chemometric approaches. First, in screening experiments, fractional factorial design (FFD) was used for selecting the variables which significantly affected the extraction procedure. Afterwards, the significant variables were optimized using response surface methodology (RSM) based on central composite design (CCD). Under the optimum conditions, the enrichment factors were 6890-8830. The linear range was 0.025-625 ng g(-1) and limits of detection (LODs) were between 0.012 and 0.2 ng g(-1). The relative standard deviations (RSDs) were in the range of 4.06-8.9% (n=6). The relative recoveries of OPPs from different soil samples were 85-98%.

This study examines the impact of this increase on a range of smoking behaviors among youth aged 12 to 17 and young adults aged 18 to 25. METHODS: Data from the 2002-2011 National Survey on Drug Use and Health (NSDUH) were used to estimate the impact of the tax increase on five smoking outcomes: (1) past year smoking initiation, (2) past-month smoking, (3) past year smoking cessation, (4) number of days cigarettes were smoked during the past month, and (5) average number of cigarettes smoked per day. Each model included individual and state-level covariates and other tobacco control policies that coincided with the tax increase. We examined the impact overall and by race and gender.

The hydrophobic DVB moieties were dedicated for extraction while the hydrophilic sulfonate groups were designed for dispersing the MNPs in aqueous sample solution. Thus, the specially designed material could ensure operational convenience and improve reproducibility during extraction. The application of the material was demonstrated by the extraction of polycyclic aromatic hydrocarbons (PAHs) from environmental water samples followed by gas chromatography-mass spectrometric analysis. The main factors influencing the extraction, including the type of the desorption solvent, the agitation mode, the amount of MNPs, extraction and desorption time and salt addition in sample solution, were investigated in detail. Under the optimized conditions, the proposed method showed satisfactory reproducibility with intra-day and inter-day relative standard deviations less than 16.5% and 21.2%, and low limits of detection of 1.1pgmL(-1), 0.8pgmL(-1), 1.1pgmL(-1), 1.4pgmL(-1), 0.6pgmL(-1), 2.1pgmL(-1) and 0.7pgmL(-1) for naphthalene, acenaphthene, fluorine, phenanthrene, anthracene, fluoranthene and pyrene, respectively. The developed method was also successfully used for determination of the PAHs in genuine lake and river environmental water samples by standard addition method. All the studied PAHs were detected in these waters with comparable results by the standard liquid-liquid extraction method. The developed MNPs with dual property of hydrophobicity and hydrophilicity were suitable for the treatment of water samples. The magnetic solid phase extraction based on this material was reliable and convenient. It has great potential in the preconcentration of trace analytes in complex matrix.

In contrast, smokeless tobacco use historically has been associated with certain sports, such as baseball (2). Athletes might be more likely to use certain tobacco products, such as smokeless tobacco, if they perceive them to be harmless (3); however, smokeless tobacco use is not safe and is associated with increased risk for pancreatic, esophageal, and oral cancers (4). Tobacco use among youth athletes is of particular concern, because most adult tobacco users first try tobacco before age 18 years (5). To examine prevalence and trends in current (>/=1 day during the past 30 days) use of combustible tobacco (cigarettes, cigars) and smokeless tobacco (chewing tobacco, snuff, or dip [moist snuff]) products among athlete and nonathlete high school students, CDC analyzed data from the 2001-2013 National Youth Risk Behavior Surveys. Current use of any tobacco (combustible or smokeless tobacco) significantly declined from 33.9% in 2001 to 22.4% in 2013; however, current smokeless tobacco use significantly increased from 10.0% to 11.1% among athletes, and did not change (5.9%) among nonathletes. Furthermore, in 2013, compared with nonathletes, athletes had significantly higher odds of being current smokeless tobacco users (adjusted odds ratio [AOR] = 1.77, p Descriptors Links Book Title Database Publisher Data Source Authors Agaku,I.T., Singh,T., Jones,S.E., King,B.A., Jamal,A., Neff,L., Caraballo,R.S.

The fabricated TiO2NS coating exhibits higher specific surface area and more active sites, it also provides an ideal nanostructure and a robust substrate for subsequent surface modification. These characteristics were useful for efficient extraction. The SPME performance of phenyl-functionalized TiO2NS-Ti (ph-TiO2NS-Ti) fiber was evaluated by using ultraviolet filters, polychlorinated biphenyls and polycyclic aromatic hydrocarbons (PAHs) as model compounds coupled to high performance liquid chromatography with UV detection (HPLC-UV). It was found that the ph-TiO2NS-Ti fiber exhibited high extraction capability, good selectivity and rapid mass transfer for PAHs. The main parameters affecting extraction performance were investigated and optimized. Under optimized conditions, the proposed fiber showed good extraction efficiency comparable to those of commercial polydimethylsiloxane and polyacrylate fibers toward PAHs. The calibration graphs were linear over the range of 0.05-300 microg L(-1). The limits of detection of the proposed method were 0.008-0.043 microg L(-1) (S/N=3). Single fiber repeatability varied from 3.51% to 5.23% and fiber-to-fiber reproducibility ranged from 4.43% to 7.65% for the extraction of water spiked with 25 microg L(-1) each analyte (n=5). The established SPME-HPLC-UV method was successfully applied to selective concentration and sensitive determination of target PAHs from real environmental water samples with recoveries from 86.2% to 112% at the spiking level of 10 microg L(-1) and 50 microg L(-1). The relative standard deviations were below 9.45%. Furthermore, the ph-TiO2NS-Ti fiber can be fabricated in a reproducible manner, and has high stability and long service lifetime.

Knowledge and perceptions of risks and benefits of tobacco products impact adolescents' decisions to use these products. However, little is known regarding adolescents' knowledge and perceptions of risks of e-cigarettes and marijuana nor how these perceptions are formed. This study uses qualitative techniques to assess and compare adolescents' perceptions of the risks and benefits of cigarettes, e-cigarettes, and marijuana. METHODS: Twenty-four adolescents (nine females and 15 males) from Northern California participated in six small-group discussions. Adolescents were asked what good or bad things might happen from using these products. To assess how perceptions and knowledge of risks and benefits were formed, participants were asked where and from whom they had learned about these products. RESULTS: Adolescents described negative consequences of cigarette use but were much less sure regarding risks of marijuana and e-cigarette use. Conversely, they described few benefits of cigarettes but described a number of benefits of e-cigarette and marijuana use. Adolescents described learning about these products from the media, from family and friends, and from the school environment. CONCLUSIONS: Adolescents have learned from multiple sources about risks of using cigarettes, but they receive much less and often incorrect information regarding marijuana and e-cigarettes, likely resulting in their positive and often ambivalent perceptions of marijuana and e-cigarettes.
