METHODS: A nationally representative probability-based cross-sectional survey of 1836 current or recently former adult smokers was completed in November 2011. Multivariate logistic regressions evaluated associations between alternative tobacco product use and smoking cessation behaviors. RESULTS: Of the smokers, 38% had tried an alternative tobacco product, most frequently e-cigarettes. Alternative tobacco product use was associated with having made a quit attempt, and those intending to quit were significantly more likely to have tried and to currently use the products than were smokers with no intentions to quit. Use was not associated with successful quit attempts. Interest in future use of alternative tobacco products was low, except for e-cigarettes. CONCLUSIONS: Alternative tobacco products are attractive to smokers who want to quit smoking, but these data did not indicate that alternative tobacco products promote cessation. Unsubstantiated overt and implied claims that alternative tobacco products aid smoking cessation should be prohibited.

The authors conducted this study to determine whether cigar and pipe smokers were at greater risk of experiencing tooth loss and alveolar bone loss than were nonsmokers. METHODS: The authors studied 690 dentate men who participate in the Veterans Affairs Dental Longitudinal Study. Subjects are not VA patients, and they receive medical and dental care in the private sector. A board-certified periodontist conducted clinical examinations triennially for 23 years. These examinations included the number of teeth remaining, number of decayed and filled surfaces per tooth, and indicator scores for plaque, calculus, pocket probing depth, gingival bleeding and tooth mobility. Alveolar bone loss was assessed at each examination on intraoral periapical radiographs using the Schei ruler method, which measures loss of bone height in 20 percent increments. Multivariate analyses of tooth-loss rates and alveolar bone loss controlled for demographic and oral hygiene measures. RESULTS: The relative risk, or RR, of tooth loss compared with that of nonsmokers was significantly elevated in cigar smokers (RR = 1.3, 95 percent confidence interval, or CI, = 1.2, 1.5), pipe smokers (RR = 1.6, 95 percent CI = 1.4, 1.9) and cigarette smokers (RR = 1.6, 95 percent CI = 1.5, 1.7). The percentages of mesial and distal sites with moderate-to-severe progression of alveolar bone loss (a change of 40 percent or more from baseline) were 8 +/- 1 percent (mean +/- standard error) in nonsmokers, 16 +/- 3 percent in cigar smokers (P < .05), 13 +/- 4 percent in pipe smokers (P = .17), and 16 +/- 3 percent in cigarette smokers (P < .001). Pipe and cigar smokers did not differ significantly from nonsmokers with respect to the percentage of sites at baseline with moderate-to-severe scores for calculus, pocket probing depth, gingival bleeding or tooth mobility. Pipe smokers had fewer sites with moderate-to-severe plaque accumulation than did nonsmokers (7 +/- 11 vs. 13 +/- 17, P < .05). CONCLUSIONS: The authors found that men who smoke cigars or pipes were at increased risk of experiencing tooth loss. Cigar smokers also were at increased risk of experiencing alveolar bone loss. These elevations in risk are similar in magnitude to those observed in cigarette smokers. CLINICAL IMPLICATIONS: The increases in risk related to cigar and pipe smoking provide a strong rationale for targeting smoking prevention and smoking cessation programs to smokers of all tobacco products.

We report the case of a 25-year-old man admitted for haemoptysis, with unfavourable outcome and acute respiratory failure. Various explorations concluded to acute respiratory distress syndrome secondary to diffuse alveolar haemorrhage. Etiological assessment was initially negative. Outcome was favourable during hospitalization, authorizing the discharge of our patient. Two days later, alveolar haemorrhage recur, with positive toxicological tests for cannabis and the patient admits smoking cannabis by plastic "bang". We illustrate, through this case, the severity of respiratory complications caused by new methods of using cannabis, particularly with plastic 'bang', hence the need to insist of the importance of supported withdrawal and to inform young people how these techniques are serious.ssss.

Ammonia-oxidizing bacteria in a chloraminated distribution sytem: Seasonal occurrence, distribution, and disinfection resistance	1990	Wolfe, R.L., Metropolitan Water District, La Verne, CA 91750, United States	Read more...

Pub Date Free Form 1990/ Volume 56 Issue 2 Start Page 451 Other Pages 462 Notes Place of Publication ISSN/ISBN 0099-2240 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Nutrification in chloraminated drinking water can have a number of adverse effects on water quality, including a loss of total chlorine and ammonia-N and an increase in the concentration of heterotrophic plate count bacteria and nitrite. To understand how nitrification develops, a study was conducted to examine the factors that influence the occurrence of ammonia-oxidizing bacteria (AOB) in a chloraminated distribution system. Samples were collected over an 18-month period from a raw-water source, a conventional treatment plant effluent, and two covered, finished-water reservoirs that previously experienced nitrification episodes. Sediment and biofilm samples were collected from the interior wall surfaces of two finished-water pipelines and one of the covered reservoirs. The AOB were enumerated by a most-probable-number technique, and isolates were isolated and identified. The resistance of naturally occurring AOB to chloramines and free chlorine was also examined. The results of the monitoring program indicated that the levels of AOB, identified as members of the genus Nitrosomonas, were seasonally dependent in both source and finished waters, with the highest levels observed in the warm summer months. The concentrations of AOB in the two reservoirs, both of which have floating covers made of synthetic rubber (Hypalon; E.I. du Pont de Nemours and Co., Inc., Wilmington, Del.), had most probable numbers that ranged from 300/ml and correlated significantly with temperature and levels of heterotrophic plate count bacteria. No AOB were detected in the chloraminated reservoirs when the water temperature was below 16 to 18Â°C. The study indicated that nitrifiers occur throughout the chloraminated distribution system. Higher concentrations of AOB were found in the reservoir and pipe sediment materials than in the pipe biofilm samples. The AOB were approximately 13 times more resistant to monochloramine than to free chlorine. After 33 min of exposure to 1.0 mg of monochloramine per liter (pH 8.2, 23Â°C), 99% of an AOB culture was inactivated. The amounts of this disinfectant that are currently used (1.5 mg/liter at a 3:1 ratio of chlorine to ammonia-N) may be inadequate to control the growth of these organisms in the distribution system.

Fast-growing families showed greater plasticity in allocating biomass to shoots at high nitrogen supply and to roots at low nitrogen supply than slow-growing families. Compared with the slow-growing families, short-term net ammonium uptake rate measured with an ion selective electrode was significantly greater in fast-growing families at high ammonium supply, but not at low supply. Net nitrate uptake showed the same trend, but differences among families were not significant. Results indicate that differences in seedling growth rate are partly a result of physiological differences in net nitrogen uptake efficiency and nitrogen productivity.

Epidemiology Pub Date Free Form 1991/ Volume 2 Issue 3 Start Page 224 Other Pages 229 Notes Place of Publication ISSN/ISBN 1044-3983 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Several epidemiologic studies have reported positive associations between electric distribution wiring configurations and cancer incidence, particularly among children. According to the investigators of these studies, the results indicate a possible link between cancer and exposure to 60-Hz magnetic fields, because residential magnetic fields are correlated with wiring configurations. I propose an alternate hypothesis to explain the epidemiologic observations, namely, that ground return currents in plumbing service lines are associated with electric wiring configuration, and cause the release of corrosion products in tap water, ingestion of which constitutes a risk factor for cancer. To corroborate this hypothesis, three conditions must be satisfied: (1) the magnitude of the ground return currents in water pipes is related to wiring configuration, with higher currents generally found associated with homes classified in the high-exposure categories; (2) corrosion on the internal surface of water pipe is related to alternating currents flowing on the pipe, with higher currents associated with higher rates of corrosion; and (3) ingestion of water from pipes undergoing alternating-current-related corrosive processes increases the probability of developing cancer.

The aim of this study was to evaluate strength of the bond between porcelain laminate veneers and tooth surfaces etched with acid and laser, separately and together. The teeth studied comprised 60 incisors extracted for periodontal reasons. These were divided into four groups according to etching method: group 1, acid etching alone; group 2, acid etching followed by laser etching; group 3, laser etching followed by acid etching; group 4, laser etching alone. The teeth were etched with 37% phosphoric acid and a Er,Cr:YSGG laser system. In addition, 60 IPS Empress II cylindrical blocks 2 mm in height and 5 mm in diameter were also prepared for the etched tooth surface. These blocks were bonded to the teeth with dual cured resin cement and shear tests were then performed. After the shear tests, Scanning electron microscopy images of the tooth surfaces were obtained at a magnification of x3,800. Etching with acid alone yielded the highest mean value of bond shear strength (15.4+/-3.8 MPa), while laser etching followed by acid etching gave the lowest mean value (11.5+/-4.6 MPa). The mean values of the bond shear strength for acid etching followed by laser etching and laser etching alone were 13.8+/-3.9 MPa and 12.8+/-4.6 MPa, respectively. Statistical analysis revealed no significant differences between the groups. The results suggest that laser etching is easy to apply and less time-consuming. They further suggest that the order in which the acid and laser are applied in combined treatments is important.

Since soil is a poor thermal conductor, a suitable arrangement of undersoil pipes is required in order to achieve a somewhat uniformly elevated soil temperature. Two dimensional steady temperature profiles in soil resulting from a warm water pipe having a wall temperature of 37.8C were computed for several pipe configurations and surface heat transfer coefficients of 1.36 and 136 cal.sec-1.m-2C-1. Values of heat transfer on the order of 5 cal.sec-1.sec-1.m-1 can be obtained. Calculations indicate that in order to apply this technique for the utilization of significant portions of reject heat, the system must be viewed in terms of an agricultural power plant complex encompassing large quantities of land.

The PANI film was directly electrodeposited on the platinum wire surface in sulfuric acid solution using cyclic voltammetry (CV) technique. The applicability of this coating was assessed employing a laboratory-made SPME device and gas chromatography with mass spectrometry (GC-MS) for the extraction of some PAHs from the headspace of aqueous samples. Application of wider potential range in CV led to a PANI with more stability against the temperature. The homogeneity and the porous surface structure of the film were examined by the scanning electron microscopy (SEM). The study revealed that this polymer is a suitable SPME fiber coating for extracting the selected PAHs. Important parameters influencing the extraction process were optimized and an extraction time of 40 min at 40 degrees C gave maximum peak area, when the aqueous sample was added with NaCl (20%, w/v). The synthesis of the PANI can be carried out conveniently and in a reproducible manner while it is rather inexpensive and stable against most of organic solvents. The film thickness of PANI can be precisely controlled by the number of CV cycles. The resulting thickness was roughly 20 microm after 20 cycles. At the optimum conditions, the relative standard deviation (RSD) for a double distilled water spiked with selected PAHs at ppb level were 8.80-16.8% (n = 3) and detection limits for the studied compounds were between 0.1-6 pg mL(-1). The performance of PANI was, also, compared with a commercial solid coated-based SPME fiber, carbowax/divinylbenzene (CW/DVB), under similar experimental conditions.
