The growing market for caffeinated energy drinks (CEDs) has caused concern about excessive caffeine intake and potential adverse effects, particularly among young people. The current study examined patterns of CED consumption among youth and young adults in Canada, using data from a national online survey conducted in October 2014. Data from a non-probability sample of 2040 respondents aged 12-24 from a consumer panel was weighted to national proportions; measures of CED consumption were estimated, including prevalence, excessive daily consumption, and context for use (locations and reasons)...

Traditional underground coalmine monitoring systems are mainly based on the use of wired transmission. However, when cables are damaged during an accident, it is difficult to obtain relevant data on environmental parameters and the emergency situation underground. To address this problem, the use of wireless sensor networks (WSNs) has been proposed. However, the shape of coalmine tunnels is not conducive to the deployment of WSNs as they are long and narrow. Therefore, issues with the network arise, such as extremely large energy consumption, very weak connectivity, long time delays, and a short lifetime...

Peak oxygen consumption (V̇O2peak) strongly predicts morbidity and mortality better than other established risk factors, yet mechanisms associated with its age-associated decline are unknown. Our lab has shown that V̇O2peak first begins to decrease at the same age of 19-20 weeks old in both sedentary and wheel-running, female Wistar rats (Toedebusch et al., Physiol Genomics. 48:101-15, 2016). Here, we employed a total systemic approach using unsupervised interrogation of mRNA with RNA-sequencing. The purpose of our study was to analyze transcriptomic profiles from both sedentary (SED) and wheel-running (RUN) conditions as a strategy to identify pathways in the left ventricle that may contribute to the initial reductions in V̇O2peak occurring between 19 and 27 weeks of age...

Inorganic and organic forms of arsenic (As), as well as omega-3 fatty acids were measured in 578 fish/seafood samples that belong to 15 species of commonly consumed seafood in Kuwait. Arsenic speciation data, with the toxicological profile of inorganic arsenic (iAs) and fish consumption rates were applied in a probabilistic risk assessment to estimate the risk from exposure to iAs. The nutritional benefits of omega-3-fatty acid levels in various species of fish were taken into consideration. Results showed that the mean daily intake of iAs through fish consumption among the Kuwaiti population was 0...

BACKGROUND: Problem drinking that predates enlistment into military service may contribute to the overall burden of alcohol misuse in the Armed Forces; however, evidence bearing on this issue is limited. This study examines prevalence and correlates of alcohol misuse among new U.S. Army soldiers. METHODS: Cross-sectional survey data were collected from soldiers reporting for basic combat training. The survey retrospectively assessed lifetime alcohol consumption and substance abuse/dependence, enabling estimation of the prevalence of lifetime binge drinking and heavy drinking in a sample of 30,583 soldiers and of probable alcohol use disorder (AUD) among 26,754 soldiers with no/minimal lifetime use of other drugs...

BACKGROUND AND AIMS: Adolescents with Intellectual Disability (ID) are at risk for tobacco and alcohol use, yet little or no prevention programs are available for this group. 'Prepared on time' is an e-learning program based on the attitude - social influence - efficacy model originally developed for fifth and sixth grades of mainstream primary schools. The goals of this study were (1) to examine the lifetime use of tobacco and alcohol among this target group and (2) to gain a first impression of the efficacy of 'Prepared on time' among 12-16-year old students with moderate or mild ID (MMID)...

Alcohol-induced hippocampal atrophy has been well documented in many studies and is known to affect various subfields. Given the functional heterogeneity of these subfields, we investigated the precise effects of alcohol-induced damage in these areas. Twenty-six male patients with alcohol dependence (alcohol group) and twenty-six age-matched male healthy social drinkers were recruited from a mental health hospital and the community respectively, with the aim of comparing the hippocampal subfields between groups...

In this paper, a novel routing strategy to cater the energy consumption and delay sensitivity issues in deep underwater wireless sensor networks is proposed. This strategy is named as ESDR: Event Segregation based Delay sensitive Routing. In this strategy sensed events are segregated on the basis of their criticality and, are forwarded to their respective destinations based on forwarding functions. These functions depend on different routing metrics like: Signal Quality Index, Localization free Signal to Noise Ratio, Energy Cost Function and Depth Dependent Function...

Motivational models have been shown to usefully describe reasons for engaging in addictive behaviors including gambling disorder. Although most scales designed to measure motives have been derived statistically, self-generated open-ended responses have also shown utility for identifying unique motives for gambling. While the motivational structure for gambling disorder has been extensively explored, there has been a paucity of research examining motives for choosing not to gamble. This is not the case for other addictive behaviors such as alcohol use where motives for abstaining from drinking have been well defined...

Emotional dysregulation in alcoholism (ALC) may result from disturbed inhibitory mechanisms. We therefore tested emotion and alcohol cue reactivity and inhibitory processes using negative priming. To test the neural correlates of cue reactivity and negative priming, 26 ALC and 26 age-matched controls underwent functional MRI performing a Stroop color match-to-sample task. In cue reactivity trials, task-irrelevant emotion and alcohol-related pictures were interspersed between color samples and color words. In negative priming trials, pictures primed the semantic content of an alcohol or emotion Stroop word...

BACKGROUND: Inconsistent associations between modifiable risk factors and chronic back pain (CBP) may be due to the inability of traditional epidemiologic study designs to properly account for an array of potential genetic and environmental confounding factors. The co-twin control research design, comparing modifiable risk factors in twins discordant for CBP, offers a unique way to remove numerous confounding factors. PURPOSE: The study aimed to examine the association of modifiable lifestyle and psychological factors with lifetime CBP...

A biomonitoring study was conducted to evaluate levels of eleven polycyclic aromatic hydrocarbons (PAHs) in water, sediment and wild Nile tilapia (Oreochromis niloticus) samples collected up- and downstream of Cairo sector of the River Nile, Egypt. The scaled mass index (SMI), as a fish body mass-length relationship, performed better in indicating the ecosystem and fish conditions. The total PAHs in water samples had a range of 0.0156-0.0269 mg/L, while that in sediment samples ranged from 0.723 to 1.078 mg/kg dry weight and that in fish muscles ranged from 4...

BACKGROUND: Previous epidemiological studies suggest that patients diagnosed with nonalcoholic fatty liver disease (NAFLD) who drink light to moderate amounts of alcohol (up to ~30 g per day) have less severe histological lesions compared with nondrinkers. However, while the cross-sectional nature of current evidence precludes assessment of causality, cumulative lifetime-exposure of moderate alcohol consumption on histological outcomes has never been evaluated. AIM: To overcome these limitations, a Mendelian randomisation study was performed using a validated genetic variant (rs1229984 A;G) in the alcohol dehydrogenase (ADH1B) gene as a proxy of long-term alcohol exposure...
