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 We searched for trials, published or unpublished, in any language, and especially in regions where waterpipe use is widespread.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.

We systematically reviewed the literature, searching MEDLINE, EMBASE and Web of Science, for interventions targeting prevention and cessation of waterpipe tobacco smoking. We assessed the evidence quality using the Cochrane (randomised studies), GRADE (non-randomised studies) and CASP (qualitative studies) frameworks. Data were synthesised narratively due to heterogeneity. We included four individual-level, five group-level, and six legislative interventions. Of five randomised controlled studies, two showed significantly higher quit rates in intervention groups (bupropion/behavioural support versus placebo in Pakistan; 6 month abstinence relative risk (RR): 2.3, 95% CI 1.4-3.8); group behavioural support versus no intervention in Egypt, 12 month abstinence RR 3.3, 95% CI 1.4-8.9). Non-randomised studies showed mixed results for cessation, behavioural, and knowledge outcomes. One high quality modelling study from Lebanon calculated that a 10% increase in waterpipe tobacco taxation would reduce waterpipe tobacco demand by 14.5% (price elasticity of demand -1.45). In conclusion, there is a lack of evidence of effectiveness for most waterpipe interventions. While few show promising results, higher quality interventions are needed. Meanwhile, tobacco policies should place waterpipe on par with cigarettes. Descriptors Links Book Title Database Publisher Data Source Authors Jawad,M., Jawad,S., Waziry,R.K., Ballout,R.A., Akl,E.A.

Higher levels of adherence to these medications increase the likelihood of sustained smoking cessation, but many smokers use them at a lower dose and for less time than is optimal. It is therefore important to determine the effectiveness of interventions designed specifically to increase medication adherence. Such interventions may include further educating individuals about the value of taking medications and providing additional support to overcome problems with maintaining adherence. OBJECTIVES: The primary objective of this review was to assess the effectiveness of interventions to increase adherence to medications for smoking cessation, such as NRT, bupropion, nortriptyline and varenicline (and combination regimens). This was considered in comparison to a control group, typically representing standard care. Secondary objectives were to i) assess which intervention approaches are most effective; ii) determine the impact of interventions on potential precursors of adherence, such as understanding of the treatment and efficacy perceptions; and iii) evaluate key outcomes influenced by prior adherence, principally smoking cessation. SEARCH METHODS: We searched the following databases using keywords and medical subject headings: Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), MEDLINE (OVID SP) (1946 to July Week 3 2014), EMBASE (OVID SP) (1980 to Week 29 2014), and PsycINFO (OVID SP) (1806 to July Week 4 2014). The Cochrane Tobacco Addiction Group Specialized Register was searched on 9th July 2014. We conducted forward and backward citation searches. SELECTION CRITERIA: Randomised, cluster-randomised or quasi-randomised studies in which participants using active pharmacological treatment for smoking cessation are allocated to an intervention arm or a control arm. Eligible participants were adult (18+) smokers. Eligible interventions comprised any intervention that differed from standard care, and where the intervention content had a clear principal focus on increasing adherence to medications for tobacco dependence. Acceptable comparison groups were those that provided standard care, which depending on setting may comprise minimal support or varying degrees of behavioural support. Included studies used a measure of adherence behaviour that allowed some assessment of the degree of adherence. DATA COLLECTION AND ANALYSIS: Two review authors searched for studies and independently extracted data for included studies. Risk of bias was assessed according to the Cochrane Handbook guidance. For continuous outcome measures, we report effect sizes as standardised mean differences (SMDs). For dichotomous outcome measures, we report effect sizes as relative risks (RRs). We obtained pooled effect sizes with 95% confidence intervals (CIs) using the fixed effects model. MAIN RESULTS: Our search strategy retrieved 3165 unique references and we identified 31 studies as potentially eligible for inclusion. Of these, 23 studies were excluded at full-text screening stage or identified as studies awaiting classification subject to further information. We included eight studies involving 3336 randomised participants. The interventions were all additional to standard behavioural support and typically provided further information on the rationale for, and emphasised the importance of, adherence to medication, and supported the development of strategies to overcome problems with maintaining adherence.Five studies reported on whether or not participants achieved a specified satisfactory level of adherence to medication. There was evidence that adherence interventions led to modest improvements in adherence, with a relative risk (RR) of 1.14 (95% CI, 1.02 to 1.28, P = 0.02, n = 1630).

Possible approaches to reduce the exposure to toxins from smoking include reducing the amount of tobacco used, and using less toxic products. The interventions evaluated in controlled trials have predominantly attempted to reduce the number of cigarettes smoked. OBJECTIVES: To assess the effect of interventions intended to reduce the harm from smoking on the following: biomarkers of damage caused by tobacco, biomarkers of tobacco exposure, number of cigarettes smoked, quitting, and long-term health status. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Group Specialised Register using free text and MeSH terms for harm reduction, smoking reduction and cigarette reduction. The initial search was in March 2006, updated in March 2007. SELECTION CRITERIA: Randomized or quasi-randomized controlled trials of interventions in tobacco users to reduce amount smoked, or to reduce harm from smoking by means other than cessation. Outcomes were change in cigarette consumption, markers of cigarette exposure and any markers of damage or benefit to health, measured at least six months from the start of the intervention. DATA COLLECTION AND ANALYSIS: We pooled trials with similar interventions and outcomes using a fixed-effect model. Other studies were summarised narratively. MAIN RESULTS: The 13 included trials all evaluated interventions to help smokers cut down the amount smoked. Self-reported reduction in cigarettes per day (CPD) was validated by reduction in carbon monoxide (CO) levels. Most trials tested nicotine replacement therapy (NRT) to assist reduction. No eligible studies evaluated the use of potentially reduced-exposure products. In a pooled analysis of eight trials, NRT significantly increased the odds of reducing CPD by 50% or more for people using nicotine gum or inhaler or a choice of product compared to placebo (n=3273, odds ratio [OR] 2.02, 95% confidence interval [CI] 1.55 to 2.62). Where average changes from baseline were compared for different measures, CO and cotinine consistently showed smaller reductions than CPD. Whilst the effect for NRT was significant, small numbers of people in either treatment or control group successfully sustained a reduction of 50% or more. Use of NRT also significantly increased the odds of quitting (OR 1.90, 95% CI 1.46 to 2.47). One trial of bupropion failed to detect an effect on reduction or cessation. Four trials of different types of advice and instructions on reducing CPD did not provide clear evidence. AUTHORS' CONCLUSIONS: There is insufficient evidence about long-term benefit to give firm support the use of interventions intended to help smokers reduce but not quit tobacco use. Some people who do not wish to quit can be helped to cut down the number of cigarettes smoked and reduce their carbon monoxide levels by using nicotine gum or nicotine inhaler. Because the long-term health benefit of a reduction in smoking rate is unclear this application of NRT is more appropriately used as a precursor to quitting.

The diagnosis of Barrett's esophagus is based on finding of intestinal metaplasia of at least 3 cm of the distal esophagus. The diagnosis of intestinal metaplasia of less than 3 cm of the distal esophagus is controversial, regarding implications with GERD, adenocarcinoma, and Helicobacter pylori. The aims of the study were to determine the prevalence of intestinal metaplasia in the distal esophagus in patients with short segments of esophageal columnar-appearing mucosa (less than 3 cm), diagnosed endoscopically, in two groups of patients, with and without symptoms of GERD. In total, 97 patients were examined, with endoscopic finding of esophageal columnar-appearing mucosa less than 3 cm. From the total, 52 patients had symptoms of GERD and 45 patients were without these symptoms. These patients were subjected to distal esophageal biopsies obtained immediately below the epithelial transition. The biopsies were stained with hematoxylin-eosin and alcian blue at pH 2.5. Urease test for H. pylori detection in two fragments of gastric antrum was carried out. The presence of intestinal metaplasia in the distal esophagus was diagnosed in 16 (30.8%) patients in the GERD group and 12 (26.7%) patients without GERD symptoms. No statistical differences were observed (P = 0.82; 95% CI: 0.61-2.17). The variables sex, mean age and positivity for H. pylori did not show statistical differences. This study diagnosed high prevalence of intestinal metaplasia in the distal esophagus with columnar-appearing mucosa, less than 3 cm, with no statistical differences in the two groups studied with and without GERD symptoms.

Once thought to be the primary cause of decompression sickness (DCS), it has been demonstrated that, even in large quantities, their presence does not always result in injury. Normally, VGE are trapped in the site of gas exchange in the lungs and eliminated via diffusion. When VGE crossover takes place in arterial circulation, they have the potential to cause more harm as they are redistributed to the brain, spinal column, and other sensitive tissues. The patent foramen ovale (PFO) was once thought to be the only risk factor for an increase in arterialization; however, IPAVAs represent another pathway for this crossover to occur. The opening of IPAVAs is associated with exercise and hypoxic gas mixtures, both of which divers may encounter. The goal of this review is to describe how IPAVAs may impact diving physiology, specifically during decompression, and what this means for the individual diver as well as the future of commercial and recreational diving. Future research must continue on the relationship between IPAVAs and the environmental and physiological circumstances that lead to their opening and closing, as well as how they may contribute to diving injuries such as DCS.

This research investigates the degree to which bone collagen delta(13) C and delta(15) N values normally vary within the skeleton and examines the influence of several diseases common to ancient populations on these isotopic compositions. The samples derive from two medieval German cemeteries and one Swiss reference collection and include examples of metabolic disease (rickets/osteomalacia), degenerative joint disease (osteoarthritis), trauma (fracture), infection (osteomyelitis), and inflammation (periostitis). A separate subset of visibly nonpathological skeletal elements from the German collections established normal intraindividual variation. For each disease type, tests compared bone lesion samples to those near and distant to the lesions sites. Results show that normal (nonpathological) skeletons exhibit limited intraskeletal variation in carbon- and nitrogen-isotope ratios, suggesting that sampling of distinct elements is appropriate for paleodiet studies. In contrast, individuals with osteomyelitis, healed fractures, and osteoarthritis exhibit significant intraskeletal differences in isotope values, depending on whether one is comparing lesions to near or to distant sites. Skeletons with periostitis result in significant intraskeletal differences in nitrogen isotope values only, while those with rickets/osteomalacia do not exhibit significant intraskeletal differences. Based on these results, we suggest that paleodiet researchers avoid sampling collagen at or close to lesion sites because the isotope values may be reflecting both altered metabolic processes and differences in diet relative to others in the population.

The bacterial communities involved in production of koumiss play a crucial role in the fermentation cycle. To reveal bacterial biodiversity in koumiss and the dynamics of succession in bacterial populations during fermentation, 22 samples were collected from 5 sampling sites and the full length of the 16S ribosomal RNA genes sequenced using single molecule real-time sequencing technology. One hundred forty-eight species were identified from 82 bacterial genera and 8 phyla. These results suggested that the structural difference in the bacterial community could be attributed to geographical location. The most significant difference in bacterial composition occurred in samples from group D compared with other groups. The sampling location of group D was distant from the city and maintained the primitive local nomadic life. The dynamics of succession in bacterial communities showed that Lactobacillus helveticus increased in abundance from 0 to 9 h and reached its peak at 9 h and then decreased. In contrast, Enterococcus faecalis, Enterococcus durans, and Enterococcus casseliflavus increased gradually throughout the fermentation process, and reached a maximum after 24 h.
