Objective To assess how easily minors can purchase cigarettes online and online cigarette vendors’ compliance with federal age/ID verification and shipping regulations, North Carolina’s 2013 tobacco age verification law, and federal prohibitions on the sale of non-menthol flavoured cigarettes or those labelled or advertised as light’. Methods In early 2014, 10 minors aged 14–17 attempted to purchase cigarettes by credit card and electronic check from 68 popular internet vendors. Results Minors received cigarettes from 32.4% of purchase attempts, all delivered by the US Postal Service (USPS) from overseas sellers. None failed due to age/ID verification. All failures were due to payment processing problems. USPS left 63.6% of delivered orders at the door with the remainder handed to minors with no age verification. 70.6% of vendors advertised light cigarettes and 60.3% flavoured, with 23.5% and 11.8%, respectively, delivered to the teens. Study credit cards were exposed to an estimated $7000 of fraudulent charges. Conclusions Despite years of regulations restricting internet cigarette sales, poor vendor compliance and lack of shipper and federal enforcement leaves minors still able to obtain cigarettes (including light’ and flavoured) online. The internet cigarette marketplace has shifted overseas, exposing buyers to widespread credit card fraud. Federal agencies should rigorously enforce existing internet cigarette sales laws to prevent illegal shipments from reaching US consumers, shut down non-compliant and fraudulent websites, and stop the theft and fraudulent use of credit card information provided online. Future studies should assess whether these agencies begin adequately enforcing the existing laws.
BackgroundLa Sal del Rey ("the King's Salt") is one of several naturally-occurring salt lakes in Hidalgo County, Texas and is part of the Lower Rio Grande Valley National Wildlife Refuge. The research objective was to isolate and characterize halophilic microorganisms from La Sal del Rey. Water samples were collected from the lake and a small creek that feeds into the lake. Soil samples were collected from land adjacent to the water sample locations. Sample salinity was determined using a refractometer. Samples were diluted and cultured on a synthetic saline medium to grow halophilic bacteria. The density of halophiles was estimated by viable plate counts. A collection of isolates was selected, gram-stained, tested for catalase, and characterized using API 20E® test strips. Isolates were putatively identified by sequencing the 16S rDNA. Carbon source utilization by the microbial community from each sample site was examined using EcoPlate™ assays and the carbon utilization total activity of the community was determined.ResultsResults showed that salinity ranged from 4 parts per thousand (ppt) at the lake water source to 420 ppt in water samples taken just along the lake shore. The density of halophilic bacteria in water samples ranged from 1.2 × 102 - 5.2 × 103 colony forming units per ml (cfu ml-1) whereas the density in soil samples ranged from 4.0 × 105 - 2.5 × 106 colony forming units per gram (cfu g-1). In general, as salinity increased the density of the bacterial community decreased. Microbial communities from water and soil samples were able to utilize 12 - 31 carbon substrates. The greatest number of substrates utilized was by water-borne communities compared to soil-based communities, especially at lower salinities. The majority of bacteria isolated were gram-negative, catalase-positive, rods. Biochemical profiles constructed from API 20E® test strips showed that bacterial isolates from low-salinity water samples (4 ppt) showed the greatest phenotypic diversity with regards to the types and number of positive tests from the strip. Isolates taken from water samples at the highest salinity (420 ppt) tended to be less diverse and have only a limited number of positive tests. Sequencing of 16S DNA displayed the presence of members of bacterial genera Bacillus, Halomonas, Pseudomonas, Exiguobacterium and others. The genus Bacillus was most commonly identified. None of the isolates were members of the Archaea probably due to dilution of salts in the samples.ConclusionsThe La Sal del Rey ecosystem supports a robust and diverse bacterial community despite the high salinity of the lake and soil. However, salinity does appear to a limiting factor with regards to the density and diversity of the bacterial communities that inhabit the lake and surrounding area.
Fibromyalgia (FM) is a chronic pain condition characterized by tenderness, fatigue, stiffness, joint pain, and physical and emotional distress. Depression is common, as well, and stress may be perceived as more severe. The current study examines perceived stress in adults ages 50 and older with and without FM. It was hypothesized that individuals with FM and/or depression would subjectively rate stressors as more severe compared to those without. Ninety-four participants (53% with FM, 78% female) aged 50 to 93 (M = 67.72, SD = 9.26) were administered an updated version of the Social Readjustment Rating Scale (SRRS) to assess amount of stress experienced in the past year. The difference between the SRRS pre-determined values and participants’ subjective ratings was calculated. Lower difference scores indicated that self-reported severity exceeded standardized values. Hierarchical linear regression analyses revealed that older adults and men were less likely to report exaggerated stressor severity (p < .05). Controlling for age and gender, individuals with FM were significantly more likely to report stressor severity far above standardized severity scores (p < .05). Results also revealed that both depression and chronic pain impact stress ratings, but impact is significantly greater for depression (p < .001). When controlling for depression, FM impact is no longer significant, suggesting that depression is a stronger predictor of subjective stress. The findings emphasize the importance of stress management and lifestyle changes to reduce the likelihood of depression and stress perception in individuals experiencing chronic pain.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
