Abstract
AIM: Identification of the predominant lactic acid bacteria (LAB) involved in spontaneous fermentations of Almagro eggplants, and evaluation of the biodiversity by molecular typing. METHODS AND RESULTS: Almagro eggplant fermentations in three factories (A, B and C) enjoying Protected Designation of Origin (PDO) status were monitored by chemical and microbiological analysis of brines. LAB isolates from brines were identified by phenotypic analysis and by species-specific PCR reactions and typed by randomly amplified polymorphic DNA (RAPD)-PCR. All isolates from factories A and C belonged to the genus Lactobacillus (Lact.), whereas isolates from factory B belonged to Lactobacillus (50%), Leuconostoc (Ln.) (25%) and Lactococcus (Lc.) (25%); 1.9% of this microbiota was considered cosmopolitan. The genera Leuconostoc and Lactococcus and the species Lact. acidophilus and Lact. paracasei had never previously been reported in Almagro eggplant fermentations. CONCLUSION: Considerable differences in the composition of the lactic acid microbiota participating in the Almagro eggplant fermentations exist. Brine NaCl concentration has a notable influence both in number and in the species participating. SIGNIFICANCE AND IMPACT OF THE STUDY: The original aspect of this work consists of an ecological study of the LAB taking part in spontaneous Almagro eggplant fermentations from different factories. Participation of Leuconostoc and Lactococcus species and of Lact. acidophilus and Lact. paracasei, which had never before been described for this pickle, and the evidence that a lactic fermentation does not always take place, were the most relevant results.

Abstract
BACKGROUND: Waterpipe smoking is a traditional method of tobacco use, especially in the Eastern Mediterranean Region, but its use is now spreading throughout Europe and North America. It is smoked socially, often being shared between friends or family at home, or in dedicated bars and cafes that provide waterpipes to patrons. Because the smoke passes through a reservoir of water, waterpipe tobacco smoking is perceived as being less lethal than other methods of tobacco use. At least in some cultures, women and girls are more likely to use a waterpipe than to use other forms of tobacco, and it is popular among younger smokers. Accumulating evidence suggests that waterpipe smoking may be as addictive as other forms of tobacco use, and may carry similar or greater risks to health. OBJECTIVES: To evaluate the effectiveness of tobacco cessation interventions for waterpipe users. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Review Group specialized register, in June 2007. We also searched MEDLINE, EMBASE, CINAHL and PsycINFO, using variant terms and spellings ('waterpipe' or 'narghile' or 'arghile' or 'shisha' or 'goza' or 'narkeela' or 'hookah' or 'hubble bubble'). We searched for trials, published or unpublished, in any language, and especially in regions where waterpipe use is widespread. We have also used our own existing bibliography, compiled from conducting an earlier exhaustive review of the literature on waterpipe smoking. SELECTION CRITERIA: We sought randomized, quasi-randomized or cluster-randomized controlled trials of smoking cessation interventions for waterpipe smokers of any age or gender. The primary outcome of interest was abstinence from tobacco use, preferably sustained and biochemically verified, for at least six months from the start of the intervention. DATA COLLECTION AND ANALYSIS: Each author intended to extract data and assess trial quality independently by standard Cochrane Collaboration methodologies, but no eligible trials were identified. MAIN RESULTS: We found no completed intervention trials targeting waterpipe smokers. A pilot randomized controlled trial by the authors of this review is underway, and will be reported in future updates. AUTHORS' CONCLUSIONS: Epidemiological and observational evidence suggests that waterpipe use is growing in popularity worldwide. It is widely and erroneously perceived to be less lethal than other forms of tobacco use. Women, girls, and young people are more likely to take up waterpipe smoking, especially in the Eastern Mediterranean Region. More research is needed on its addictive properties, and on the associated health risks, both for users and exposed non-smokers. Evidence-based information about waterpipe's addictive and harmful properties should be developed and disseminated in order to deglamourise and denormalise its use. High quality randomized trials are needed to guide treatment of waterpipe smoking.

Abstract
Most tobacco control efforts in western countries focus on the factory-made, mass-produced (FM) cigarette, whereas other tobacco products receive relatively little attention. Noncombusted tobacco products (i.e., referred to as smokeless tobacco), particularly Swedish-style snus, carry lower disease risks, compared with combusted tobacco products such as cigarettes. In this context, it is important to know what tobacco users believe about the relative harmfulness of various types of tobacco products. Data for this study came from random-digit-dialed telephone surveys of current smokers aged 18 or older in Australia, Canada, the United Kingdom, and the United States. Three waves of data, totaling 13,322 individuals, were assessed. Items assessed use of and beliefs about the relative harms of cigars, pipes, smokeless tobacco, and FM and roll-your-own cigarettes, as well as sociodemographics and smoking behaviors. Cigars (2.8%-12.7%) were the other tobacco products most commonly used by current cigarette smokers, followed by pipes (0.3%-2.1%) and smokeless tobacco (0.0%-2.3%). A significant minority of smokers (12%-21%) used roll-your-own cigarettes at least some of the time. About one-quarter of smokers believed that pipes, cigars, or roll-your-own cigarettes were safer than FM cigarettes, whereas only about 13% responded correctly that smokeless tobacco was less hazardous than cigarettes. Multivariate analyses showed that use of other tobacco products was most strongly related to beliefs about the reduced harm of these other products. Use of other tobacco products was low but may be growing among smokers in the four countries studied. Smokers are confused about the relative harms of tobacco products. Health education efforts are needed to correct smoker misperceptions.

Abstract
The activities of voriconazole, posaconazole, caspofungin, and anidulafungin against Candida albicans and Candida parapsilosis biofilms were evaluated. In contrast to planktonic cells, the MICs for voriconazole and posaconazole for the biofilms of the two species were high (>or=256 and >64 mg/liter, respectively) but relatively low for the echinocandins caspofungin and anidulafungin (<or=1 and <or=2 mg/liter, respectively).

Abstract
BACKGROUND AND AIM OF THE WORK: Among hospital facilities the dental unit is an environment that is at major risk of Legionella due to equipment such as the air/water syringe, the turbine, the micromotor and the scaler which generate potentially harmful aerosols that may to be a source of exposure to Legionella spp. particularly in immunodeficient patients, and those affected by chronic diseases, and also in dental personnel. Therefore, an examination of the extent of Legionella spp. contamination in the dental chairs waterlines and the incoming water supply of some public dental units is the subject of the present study. METHODS: From February 2002 to March 2004, a total of 208 water samples were collected: 160 samples from the water supply of 4 dental chair and 48 samples from the cold incoming tap water of 2 units. RESULTS: Legionella spp. was detected in 46 samples (22.1% ): 19 of them (41.3% of Legionella spp.; 9.1% of the total) were Legionella pneumophila; Pseudomonas aeruginosa was detected in 86 samples (41.4%) and both microorganisms were detected in 2 samples (0.96%). CONCLUSIONS: Our results show a microbiological condition in dental settings, that is not at all satisfactory due to the presence of Legionella in concentrations that are considered to be a health hazard (> or = 10(3)) in certain cases. Given the extent of the health risk in these surroundings, the difficulty in its assessment, and also considering the wide diffusion of general dental care, our investigation has confirmed the need to regularly monitor the microbiological condition of water in dental units.

Abstract
Surveillance of Legionella spp. in hospital water systems was performed in forty-four inpatient healthcare facilities in Spain during 2005-2006. A total of 2,341 samples were collected: 470 from cooling systems (cooling towers) and 1,871 from potable water systems. The latter included 211 from cold-water tanks and 260 from hot-water tanks, totalling 471 from central water reservoirs 136 from showers, 1,172 from unfiltered taps and 92 from filtered taps, totalling 1,400 from peripheral points. Temperature, chlorine levels and the presence of Legionella spp. were determined. In all, 373 (15.9%) samples yielded Legionella spp. Significantly higher isolation rates were obtained from cooling towers (23.8%) versus cold- and hot-water tanks (approximately 4.7%), due to the significantly higher number of samples positive for serogroup 1 (19.4 vs 0.9-3.5%). In potable water systems, no differences were found between central water tanks and showers, but significant differences in isolation rates between central water tanks and unfiltered taps were observed (4.7 vs 19.6%) due to differences in non-serogroup 1 L. pneumophila. Filters significantly decreased isolation rates of these serotypes (11 vs 0%). Some seasonal differences were noted, with higher isolation rates in summer for legionella serogroup 1 in cooling systems and for L. pneumophila serogroups 2-14 in potable water systems. In regression models, higher temperatures were associated with colonisation in cooling systems, while lower chlorine levels were associated with colonisation in potable water systems.

Abstract
Asthma disproportionately affects inner-city, minority children in the U.S. Outdoor pollutant concentrations, including particulate matter (PM), are higher in inner-cities and contribute to childhood asthma morbidity. Although children spend the majority of time indoors, indoor PM exposures have been less extensively characterized. There is a public health imperative to characterize indoor sources of PM within this vulnerable population to enable effective intervention strategies. In the present study, we sought to identify determinants of indoor PM in homes of Baltimore inner-city pre-school children. Children ages 2-6 (n=300) who were predominantly African-American (90%) and from lower socioeconomic backgrounds were enrolled. Integrated PM(2.5) and PM(10) air sampling was conducted over a 3-day period in the children's bedrooms and at a central monitoring site while caregivers completed daily activity diaries. Homes of pre-school children in inner-city Baltimore had indoor PM concentrations that were twice as high as simultaneous outdoor concentrations. The mean indoor PM(2.5) and PM(10) concentrations were 39.5+/-34.5 and 56.2+/-44.8 microg/m(3), compared to the simultaneously measured ambient PM(2.5) and PM(10) (15.6+/-6.9 and 21.8+/-9.53 microg/m(3), respectively). Common modifiable household activities, especially smoking and sweeping, contributed significantly to higher indoor PM, as did ambient PM concentrations. Open windows were associated with significantly lower indoor PM. Further investigation of the health effects of indoor PM exposure is warranted, as are studies to evaluate the efficacy of PM reduction strategies on asthma health of inner-city children.

Abstract
OBJECTIVE: There have been few studies investigating the level of cigarette smoke pollution to which people in several public and private places are exposed. The purpose of this study was to quantify the level of air pollution produced by cigarette smoking in workplaces and leisure settings. METHODS: The study was carried out in Braga, Portugal, in 2005. Nicotine content in indoor air was measured using passive monitors containing a 37-mm diameter filter inside treated with sodium bisulphate. The monitors were installed in predefined public workplaces and leisure settings. Median nicotine content was estimated for each place studied. RESULTS: Nicotine was detected in 85% of the samples. Extremely high air contamination levels were found in discos with a median of 82.26 microg/m3, ranging between 5.79 and 106.31 microg/m3. Workplaces of public administration and university buildings showed the lowest nicotine content. CONCLUSIONS: The study findings confirm the need to promote the implementation of smoke-free policies in workplaces and leisure settings to protect workers' health and as a reinforcing measure of an environment which facilitates smokers to quit smoking.

Abstract
Previous studies using traditional biochemical identification methods to study the ecology of commercial sauerkraut fermentations revealed that four species of lactic acid bacteria, Leuconostoc mesenteroides, Lactobacillus plantarum, Pediococcus pentosaceus, and Lactobacillus brevis, were the primary microorganisms in these fermentations. In this study, 686 isolates were collected from four commercial fermentations and analyzed by DNA fingerprinting. The results indicate that the species of lactic acid bacteria present in sauerkraut fermentations are more diverse than previously reported and include Leuconostoc citreum, Leuconostoc argentinum, Lactobacillus paraplantarum, Lactobacillus coryniformis, and Weissella sp. The newly identified species Leuconostoc fallax was also found. Unexpectedly, only two isolates of P. pentosaceus and 15 isolates of L. brevis were recovered during this study. A better understanding of the microbiota may aid in the development of low-salt fermentations, which may have altered microflora and altered sensory characteristics.

Abstract
A monitoring campaign of BTEX (benzene, toluene, ethylbenzene, o- m- and p-xylene) was carried out nearby two tunnel portals in the urban area of Naples with the aim to verify air quality in this kind of urban sites. Sampling was carried out using the active adsorption technique. Sampling time was 1 h. Ambient temperature and traffic flow measurements were carried out during each sampling operation. The results indicate that average benzene concentrations at both sites exceed the limit value of 10 microg/Nm3 established by the European Community (EC) (Dir. 2000/69). Concentration levels of other BTEX are relatively high as well. A correlation between BTEX concentration and two wheeler vehicle flow was observed.
