To date, no studies have tested Web-based brief alcohol intervention effectiveness over time by using a large number of measurements. OBJECTIVE: Testing whether the What Do You Drink (WDYD) Web-based brief alcohol intervention can sustain a reduction in alcohol use among heavy-drinking students aged 18-24 years at 1-, 3-, and 6-month follow-up intervals. METHODS: A purely Web-based, 2-arm, parallel-group randomized controlled trial applying an ecological momentary assessment approach with 30 weekly measurements was conducted in the Netherlands (2010-2011). Participants were recruited offline and online. A total of 907 participants were randomized into the experimental condition (n=456) including the single-session and fully automated WDYD intervention, or into the control condition (n=451) including assessment only. Weekly alcohol consumption and frequency of binge drinking were the self-assessed outcome measures. RESULTS: Attrition rates of the 907 participants were 110 (12.1%), 130 (14.3%), and 162 (17.9%) at 1-, 3-, and 6-month follow-up intervals, respectively. Latent growth curve analyses according to the intention-to-treat principle revealed that participants in the experimental condition had significantly lower weekly alcohol consumption compared to participants in the control condition that was sustained at 3-month follow-up (intercept=-2.60, P<.001 slope="0.16," p=".08)." additional="" linear="" regression="" analyses="" indicated="" that="" this="" intercept="" difference="" resulted="" from="" significantly="" higher="" levels="" of="" alcohol="" units="" per="" week="" for="" participants="" in="" the="" control="" condition="" compared="" to="" those="" experimental="" at="" se="" cohen="" d="0.20," and="" follow-up="" intervals.="" latent="" growth="" curve="" further="" had="" a="" lower="" frequency="" binge="" drinking="" was="" sustained="" outcome="" relative="" conclusions:="" wdyd="" intervention="" shown="" be="" effective="" preventing="" an="" increase="" weekly="" consumption="" directly="" after="" intervention.="" effect="" months="" trial="" registration:="" netherlands="" register="" ntr2665="" http:="" by="" webcite=""> Descriptors Links Book Title Database Publisher Data Source Authors Voogt,C., Kuntsche,E., Kleinjan,M., Poelen,E., Engels,R.

The experiment was performed with a non-aqueous binary two-phase solvent system composed of n-heptane and acetonitrile. The CCC column was first filled with the upper stationary phase, and then a large volume of water sample was pumped into the column while the CCC column was rotated at 1600 rpm. Finally, the trace amounts of PAHs extracted and enriched in the stationary phase were eluted out by the lower mobile phase and determined by gas chromatography-flame ionization detector (GC-FID) or gas chromatography-mass spectrometry (GC-MS). The enrichment and cleanup of PAHs can be fulfilled online by this method with high recoveries (84.1-103.2%) and good reproducibility (RSDs: 4.9-12.2%) for 16 EPA PAHs under the optimized CCC pretreatment conditions. This method has been successfully applied to determine PAHs in lake water where 8 PAHs were detected in the concentration of 40.9-89.9 ng/L. The present method is extremely suitable for the preparation of large volume of environmental water sample for the determination of trace amounts of organic pollutants including PAHs as studied in this paper.

The disease may show two clinical forms, i.e.: 1) the pneumonic form characterized by fever, pulmonary, neurologic and often hepatic and renal affections, severe evolution and high mortality rate; and 2) non-pneumonic form similar to influenza infection. Occurrence of the disease was mentioned almost all over the world its incidence in Europe reaching 1-3%. The infection sources are: warm water supply systems of hospitals, hotels etc.; water cooling towers, humidifier of air-conditioning systems, disperses for therapeutically applied aerosols, water sprinkling equipment, etc. Incubation period of the disease is 2-10 days. The factors favoring infection have to be looked for with all the conditions generating a decrease in activity of immunization system. Disease control steps through eliminating infection sources: water hyperchlorination, increase of water temperature in water supply systems at 60 degrees C for short periods, detachment of non-functional water pipes from the main trunk line. Occurrence of legionellosis is monitored by both active and passive means applied within the country and on an international level through the Reference Centres for Legionellosis.

The inspection of pipelines, especially those of non-man-entry size, is a particularly difficult job since the sections to be inspected extend usually over long distances and are typically laid underground. Technical installations such as photography or direct inspection with the aid of endoscopes or television cameras are in principal suitable for that purpose. Towards the end of 1987, the development of a novel television system especially well-suited for use in pressurized drinking water pipelines was completed in Germany in close cooperation with the Berliner Wasser-Betriebe. Since the summer of 1988, two camera dollies and two colour television cameras are at the disposal of the Berliner Wasser-Betriebe. The television camera is linked to a vehicle via a 200-m long cable, wound on a cable drum. The vehicle itself is fitted with several colour and monochrome monitors, a PC complete with printer, a videorecorder for recording, and holding fixtures for two reflex cameras. The monitor of the PC is, in addition, used on a leakage detector that operates in accordance with the correlation method and which is also located in the vehicle. The correlation device can, moreover, also be used as mobile equipment outside the vehicle for use on any desired location. A small portable black-and-white camera with monitor is also available for use outside the vehicle.

M. avium biofilm has recently been identified on sauna walls and in city water pipes and might have a role in the survival of virulent strains in the environment and in the host. To characterize the M. avium biofilm, an in vitro model was adapted wherein biofilm develops on a PVC surface. Biofilm was detected by staining with crystal violet and visualization by optical microscopy and quantified by A 570. M. avium strains MAC 101, MAC 100, MAC 104, MAC 109, MAC A5 and MAC 5501 (all isolated from the blood of AIDS patients) were used in the assays. Biofilm formation was dependent on the presence of Ca2+, Mg 2+ or Zn2+ ions in the water, with the maximal effect seen at a concentration of 1 Î¼M. The presence of 2% glucose and peptone as sources of carbon increased the formation of biofilm, while this was partially inhibited by humic acid. Since sliding motility has been associated with the amount of glycopeptidolipid (GPL), TLC was used to determine the presence of GPL. The supernatant of a biofilm-forming culture induced formation of a stable biofilm and amikacin blocked the establishment of biofilm by M. avium strains at subinhibitory concentrations. Bacteria in the biofilm were more resistant to chlorine as well as to exposure to potassium monopersulfate and chloroheximide acetate than were planktonic bacteria. Identification of M. avium genes involved in biofilm formation and further studies of the effect of antimicrobials on the establishment of biofilm may identify approaches for inhibiting M. avium biofilm formation and colonization.

Pub Date Free Form 1973/ Volume 24 Issue 3 Start Page 339 Other Pages 357 Notes Place of Publication ISSN/ISBN Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Among a sample of 1,252 persons from a total population of about 15,000 people of the Kpelleh tribe in the Bong Range area, 783 (63.2%) were carriers of microfilariae of O. volvulus. The infection was determined by a standardized skin biopsy technique (Walser punch). At the age of 16 to 18 yr more than 50% of the population had detectable larvae in the gluteal skin. Among the adult population the male sex showed a significant preponderance of positivity for microfilariae. The number of noninfected 'susceptibles' decreased annually by a factor of 0.92 to 0.925. About one half of a sample of adult subjects revealed microfilariae in the cephalic region. Findings of diminished vision (â‰¤ 6/60) were compared with the microfilarial density in the anterior segment and in the environment of the eyes. The rate of blindness of 1.18% found in the Bong Range was more than twice as high as in onchocerciasis free regions of Liberia. Blindness appeared to be related to onchocerciasis in the majority of cases. The average age of the completely blind was 54 yr, and the onset of blindness could be dated back to an average of 48 yr. In the unilaterally blind the average age was 40 yr. In this group blindness appeared to be less related to onchocerciasis. Among 1,131 subjects a bilaterally impaired vision was found in 8.3%. Together with the unilaterally blind, the total number of persons with visual damage besides the blind was 9.8% of the population sample at Bong Range.

The daily and annual cycles of biting densities, age composition and infection rates of the Simulium damnosum population have been studied for one or more years at 7 catching sites. Dissections of 67,758 females of S. damnosum revealed a mean annual parous rate of 10.9%; 17.2% of the parous flies carried developing filaria infections, 2.6% third stage larvae of O. volvulus, and 3.0% third stage larvae of other filaria species. An average of 900 O. volvulus larvae theoretically transmitted per man per year was calculated. This transmission potential was associated with a microfilariae carrier rate of 63% in the human population.

A temporary focus of savanna species of the Simulium damnosum complex in the forest zone of Liberia	1991	Bernhard Nocht Institute for Tropical Medicine, Bernhard-Nocht-Strasse 74, D-2000 Hamburg 36	Read more...

Pub Date Free Form 1991/ Volume 42 Issue 3 Start Page 181 Other Pages 187 Notes Place of Publication ISSN/ISBN 0177-2392 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Savanna species of the Simulium damnosum complex, the major vectors of the blinding savanna type of onchocerciasis, were considered to be rare in Liberia, until the dry season of 1988. In 1988 they became a serious nuisance, biting people at the Bong iron ore mine within the rain forest zone. S. damnosum s.str. and S. sirbanum were found breeding, in association with S. adersi a non man-biting savanna species, in a stream emerging from the mine's tailings pond. The local forest species were extremely rare in this stream. The water of the stream was characterized by an increased hardness and higher temperatures in comparison with those of natural watercourses in the area. The mass occurrence of flies was probably related to expansions of the tailings ponds, when rich nutrition was provided for the blackfly larvae by the decaying forests submerged by the rising water levels. The phenomenon did not recur in 1989 when only a few savanna flies were caught, and none were seen in the dry season of 1990 Although it is not known why the artificial environment of the tailings ponds was so attractive for the savanna species the events clearly demonstrated that savanna flies seasonally invading the area, possibly aided by the northeasterly harmattan winds, can become established in the rain forest zone if suitable conditions are met. No infections with Onchocerca volvulus were found in more than 1000 flies caught by vector collectors but, after experimental infection with the local forest strain, a few parasites developed to the infective stage. As yet there is no evidence that the occurrence of savanna flies in the rain forest zone of Liberia was of epidemiological significance.
