Abstract
BACKGROUND: Occupational and environmental exposure to petroleum refinery products poses a great threat to human health. This study aimed to assess the lung function and Fractional Exhaled Nitric Oxide (FeNO) among petroleum refinery workers. METHODS: In this cross-sectional study, 112 participants (56 petroleum refinery workers with mean age 35.20 +/- 1.62 years, and 56 age, weight, height, ethnicity and socioeconomically matched control subjects with mean age 30.02 +/- 1.76 years) were recruited. A comprehensive clinical history and examination was conducted to decide whether to include in the study or not. Ventilatory lung function test parameters were recorded by using a Spirometer and Fractional Exhaled Nitric Oxide (FeNO) was measured by Niox Mino. RESULTS: A significant decline in lung function parameters FEV1 (p = 0.0001), FEV1/FVC Ratio (p = 0.01), PEF (p = 0.0001), FEF 25 % (p = 0.0001), FEF-50 % (p = 0.012) was observed among oil refinery workers compared to their matched controls. However, there was no difference in the mean values of FeNO between the groups. CONCLUSION: Subjects working in the petroleum refinery have significantly impaired lung functions. However, there was no change in the values of FENO between the groups. The lung function impairment pattern provide evidence in the favor of an obstructive lung disease.

Abstract
INTRODUCTION: The prevalence of electronic cigarette (e-cigarette) use is increasing markedly in the general population. Yet, remarkably little research exists to examine these ongoing trends in at-risk populations, and nothing is known about the prevalence of e-cigarette use among military personnel. The purpose of the current study is to provide recent (2013-2014) data on the prevalence of regular e-cigarette use in a population of recruits prior to their entry into the U.S. military. METHODS: The study utilized a cross-sectional assessment of e-cigarette and other tobacco and nicotine-containing product (TNCP) use in 2013-2014 among 10,043 U.S. Air Force (USAF) recruits in Technical Training. Chi-square tests, the Cochran-Armitage test for trend, and logistic regression models tested differences and trends across time for e-cigarette use. RESULTS: The rate of e-cigarette use among recruits was 5.2%, which doubled (3% to 6.5%, p

Abstract
BACKGROUND: There is a dearth of studies regarding the influence of cigarette smoking on periodontal inflammatory conditions among patients with type 2 diabetes mellitus (T2DM). The aim of the present study is to assess periodontal inflammatory conditions among smokers and never-smokers with and without T2DM. METHODS: One hundred individuals (50 patients with T2DM [25 smokers and 25 never-smokers] and 50 controls [25 smokers and 25 never-smokers]) were included. Information regarding age, sex, duration and daily frequency of smoking, duration and treatment of diabetes, and oral hygiene was recorded using a questionnaire. Periodontal parameters (plaque index [PI], bleeding on probing [BOP], probing depth [PD], clinical attachment loss [AL], and marginal bone loss [MBL]) were measured. Hemoglobin A1c (HbA1c) levels were also recorded. RESULTS: Mean age, monthly income status, and education levels were comparable among smokers and never-smokers with and without T2DM. Mean HbA1c levels were significantly higher among patients with T2DM (8.2% +/- 0.1%) compared with controls (4.4% +/- 0.3%) (P /=4 mm [P

Abstract
Of increasing concern is pollution by volatile organic compounds, with particular reference to five aromatic hydrocarbons (benzene, toluene, ethyl benzene and two isomeric xylenes; BTEX). These pollutants are classified as hazardous air pollutants. Due to the potential health risks associated with these pollutants, BTEX concentrations were monitored at a bus diesel-refueling bay, in Johannesburg, South Africa, using gas chromatography, coupled with a photo-ionization detector. Results indicate that o-xylene (29-50%) and benzene (13-33%) were found to be the most abundant species of total BTEX at the site. Benzene was within South African occupational limits, but above international occupational exposure limits. On the other hand, occupational concentrations of toluene, ethyl-benzene and xylenes were within national and international occupational limits throughout the monitoring period, based on 8-hour workday weighted averages. Ethyl-benzene and p-xylene concentrations, during winter, correspond to activity at the site, and thus idling of buses during refueling may elevate results. Overall, occupational air quality at the refueling bay is a matter of health concern, especially with regards to benzene exposure, and future reduction strategies are crucial. Discrepancies between national and international limit values merit further investigation to determine whether South African guidelines for benzene are sufficiently precautionary.

Abstract
We measured the reproduction number before and after interventions were implemented to reduce Ebola transmission in 9 outbreaks in Liberia during 2014. We evaluated risk factors for secondary cases and the association between patient admission to an Ebola treatment unit (ETU) and survival. The reproduction number declined 94% from 1.7 (95% CI 1.1-2.6) to 0.1 (95% CI 0.02-0.6) after interventions began. The risk for secondary infections was 90% lower for patients admitted to an ETU (risk ratio 0.1, 95% CI 0.04-0.3) than for those who died in the community. The case-fatality rate was 68% (95% CI 60-74), and ETU admission was associated with a 50% reduction in death (hazard ratio 0.5, 95% CI 0.4-0.8). Isolation and treatment of Ebola patients had the dual benefit of interrupting community transmission and improving survival.

Abstract
Russian traditional fermented dairy foods have been consumed for thousands of years. However, little research has focused on exploiting lactic acid bacteria (LAB) resources and analyzing the LAB composition of Russian traditional fermented dairy foods. In the present study, we cultured LAB isolated from fermented mare and cow milks, sour cream, and cheese collected from Kalmykiya, Buryats, and Tuva regions of Russia. Seven lactobacillus species and the Bifidobacterium genus were quantified by quantitative PCR. The LAB counts in these samples ranged from 3.18 to 9.77 log cfu/mL (or per gram). In total, 599 LAB strains were obtained from these samples using de Man, Rogosa, and Sharpe agar and M17 agar. The identified LAB belonged to 7 genera and 30 species by 16S rRNA and murE gene sequencing and multiplex PCR assay. The predominant LAB isolates were Lactobacillus helveticus (176 strains) and Lactobacillus plantarum (63 strains), which represented 39.9% of all isolates. The quantitative PCR results revealed that counts of 7 lactobacilli species and Bifidobacterium spp. of 30 fermented cow milk samples ranged from 1.19+/-0.34 (Lactobacillus helveticus in Tuva) to 8.09+/-0.71 (Lactobacillus acidophilus in Kalmykiya) log cfu/mL of fermented cow milk (mean +/- standard error). The numbers of Bifidobacterium spp., Lb. plantarum, Lb. helveticus, and Lb. acidophilus revealed no significant difference between the 3 regions; nevertheless, Lactobacillus paracasei, Lactobacillus fermentum, Lactobacillus sakei, and Lactobacillus delbrueckii ssp. bulgaricus exhibited different degrees of variation across 3 regions. The results demonstrate that traditional fermented dairy products from different regions of Russia have complex compositions of LAB species. The diversity of LAB might be related to the type of fermented dairy product, geographical origin, and manufacturing process.

Abstract
BACKGROUND: The increasing awareness of the health risks associated with tobacco use has led many countries to enact tobacco control legislation to protect citizens from the harmful effects of tobacco use. Young people are important stakeholders in many aspects of tobacco control legislation. OBJECTIVE: This study.aims to assess the awareness of existing tobacco control laws among young people, their attitudes towards these laws and the factors associated with youth awareness and support for tobacco control legislation in Nigeria. METHODS: A descriptive cross-sectional survey was carried out among 950 students enrolled in six randomly selected public and private schools in the, Mushin local government area of Lagos state using a multi stage sampling method. The respondents completed a pre-tested self-administered questionnaire eliciting information on their awareness and support for tobacco control laws in selected thematicareas Data was analysed using SPSS 17.0 and presented as frequency tables and cross tabulations. RESULTS: Most of the participants were between 14-18 years of age (55.8%) with a mean age of 14.1 +/- 2.2 years. There were slightly more male than female respondents. About two-thirds of the respondents were aware that laws exist to regulate tobacco use in Nigeria. Specifically, more than 60% of the students knew that tobacco smoking was outlawed in schools, medical establishment, public vehicles and offices. Many were aware of the advert bans on tobacco products on television, newspapers, radio, magazines and cinemas. The respondents were however less informed of the penalties for violating tobacco restriction laws. Majority supported the law prohibiting cigarette smoking in health facilities (84.3%), schools (83.7%), public transportation (79.5%) and cinemas (76.3%). Relatively fewer (49.6%) respondents felt that smoking should be prohibited in bars, restaurants and nightclubs. A significant proportion believed that young people in Nigeria should not be allowed to buy (76.4%) or sell (76.1%) cigarettes. Few (13.7%) respondents did not support the law banning cigarette advertisement on mass forms of media. Similarly, 12.2% did not support the law allowing cigarette sponsorship and promotions by cigarette companies. Majority (83.7%) of the respondents agreed with the law banning the sale of cigarettes arouhd school premises while 66.2% supported the ban on sales of cigarettes in single sticks. Majority of the students (78.3%) agreed that health warnings should be placed on all cigarette packages while 62.5% agreed that the prices of cigarettes should be increased to discourage buyers. Up to 69.2% agreed that cigarette scenes should be prohibited in movies for kids. In general, majority (94.3%) of the respondents expressed a high level of support for tobacco related legislation. A bi-variate analysis showed students who received pocket money were found to have significantly higher levels of awareness compared with those who did not receive pocket money. (p=0.003). We also found that females were generally less supportive of tobacco control legislation compared to their male counterparts. CONCLUSION: School based education programs should be carried out to inform and educate students about existing tobacco.laws in Nigeria. Policy makers should leverage on the support of key stakeholders like young-people for-thd passage and effective implementation of tobacco control laws.

Abstract
PURPOSE: The aim of this study was to examine the prevalence, attitudes, and risk factors associated with electronic cigarette (e-cigarette) use among high school students in tobacco growing state. METHODS: A 47-item e-cigarette questionnaire modeled after Monitoring the Future with additional information about demographics, adolescent and family nicotine use, and school and health care interventions was designed, piloted, and administered to public high school students (N = 3,298) in May 2013, in an urban county in North Carolina. RESULTS: Completers (2,769/3,298) were aged 16.4 years (standard deviation +/- 1.4) with 48.9% males and 43.9% African-American, 38% white, and 4.6% Hispanics. The majority (77.3%) knew about e-cigarettes; 15.2% reported that they had tried an e-cigarette, and 60% reported that e-cigarettes were safe or had minimal health hazards. Only 5.4% reported that schools had offered information about e-cigarette use. One quarter (24.9%) reported ever cigarette smoking, and 13.3% reported ever using smokeless tobacco. E-cigarette use was positively associated with older age, tobacco use, male gender, Caucasian race, mother's e-cigarette use, biological parents' tobacco use, and lower academic performance, whereas negatively associated with having a mother who never used e-cigarettes, not knowing any e-cigarette users, and living with mother (p

Abstract
Aim of this study was to determine the prevalence and correlates of energy-drink (ED) consumption among 10th grade students in Istanbul/Turkey. Cross-sectional online self-report survey conducted in 45 schools from the 15 districts in Istanbul. The questionnaire included sections about demographic data, self-destructive behavior and use of substances including tobacco, alcohol and drugs. Also Psychological Screening Test for Adolescents (PSTA) was used. The analyses were conducted based on the 4957 subjects. Rate of those reported a ED consumption once within last year was 62.0% (n=3072), whereas rate of those reported ED consumption at least once in a month was 31.1%. There were consistent, statistically significant associations between genders, lifetime substance use (tobacco, alcohol and drug use), measures of sensation seeking, psychological problems (depression, anxiety, anger, impulsivity) and self-destructive behavior (self-harming behavior and suicidal thoughts) with ED consumption. In logistic regression models male gender, sensation seeking, life-time tobacco, alcohol and drug use predicted all frequencies of ED consumption. In addition to these predictors, anger and self-harming behavior also predicted ED consumption at least once in a month. There were no interactions between the associations of lifetime tobacco, alcohol and drug use with ED consumption. The findings suggest that the ED consumption of male students is related with three clusters of substances (tobacco, alcohol and drug) through sensation seeking and these relationships do not interact with each other.

Abstract
A simple method has been developed for the simultaneous determination of 16 polycyclic aromatic hydrocarbons (PAHs) in mainstream cigarette smoke. The procedure is based on employing a homemade graphene-coated solid-phase microextraction (SPME) fiber for extraction prior to GC/MS. In comparison to commercial 100-mum poly(dimethyl siloxane) (PDMS) fiber, the graphene-coated SPME fiber exhibits advantageous cleanup and preconcentration efficiencies. By collecting the particulate phase 5 cigarettes, the LODs and LOQs of 16 target PAHs were 0.02-0.07 and 0.07-0.22 ng/cigarette, respectively, and all of the linear correlation efficiencies were larger than 0.995. The validation results also indicate that the method has good repeatability (RSD between 4.2% and 9.5%) and accuracy (spiked recoveries between 80% and 110%). The developed method was applied to analyze two Kentucky reference cigarettes (1R5F and 3R4F) and six Chinese brands of cigarettes. In addition, the PAH concentrations in the particulate phase of the smoke from the 1R5F Kentucky cigarettes were in good agreement with recently reported results. Due to easy operation and good validation results, this SPME-GC/MS method may be an excellent alternative for trace analysis of PAHs in cigarette smoke.
