Water pipe smoking and stroke: A systematic review and meta-analysis.

Despite the damaging effects of water pipe on physical health, there is little information about the potential harmful effects of this tobacco on stroke. This study aims to investigate the relationship between water pipe smoking and stroke. A systematic review was conducted including Ovid SP, Embase, Pubmed, Web of Science, Scopus, and Google Scholar databases with focus on cohort, case-control, and cross-sectional studies. We reviewed all studies reporting on water pipe smoking and stroke. The funnel plot and the Egger regression test were used to assess publication bias. In the four eligible studies, there were a total of 2759 participants that 555 patients had at least once experienced stroke. Meta-analysis revealed positive association between water pipe smoking and stroke with pooled adjusted OR 2.79 (95%CI: 1.74-3.84; ) and the funnel plot shows asymmetry publication bias. We found a higher effect of water pipe smoking on stroke compared to cigarette smoking and concluded that water pipe increases the risk of stroke by 2.79. Hence, because most of the water pipe consumer society is young, especially women, policies and decisions need to be taken to control the supply of this tobacco to the market and more provide education on the health problem of water pipe smoking. This study provides a higher effect of water pipe smoking on stroke. Physicians and researchers who intend to study in the field of stroke should better examine the effects of water pipe (including time of use, dose-response, long-term effects, and risk factors) on stroke.

Impact of waterpipe smoking on the salivary microbiome.

While oral mirobial dysbiosis due to tobacco smoking has been studied thoroughly, there is limited data on the effect of waterpipe smoking on the oral microbiome. This study aims to compare the salivary microbiome between waterpipe smokers and non-smokers. Unstimulated saliva samples were collected from 60 participants, 30 smokers and 30 non-smokers in Kuala Lumpur and Klang Valley, Malaysia. DNA extraction was performed using the Qiagen DNA mini kit, and the 16S rRNA bacterial gene was amplified and sequenced using the Illumina MiSeq platform. Sequencing reads were processed using DADA2, and the alpha and beta diversity of the bacterial community was assessed. Significantly differentiated taxa were identified using LEfSe analysis, while differentially expressed pathways were identified using MaAsLin2. A significant compositional change (beta diversity) was detected between the two groups (PERMANOVA P < 0.05). Specifically, the levels of phylum Firmicutes and genus Streptococcus were elevated in smokers, whereas phylum Proteobacteria and genus Haemophilus were depleted compared to non-smokers. At the species level, Streptococcus oralis, Streptococcus salivarius, and Streptococcus gingivalis were enriched in smokers. We observed significant differences in the abundance of thirty-seven microbial metabolic pathways between waterpipe smokers and non-smokers. The microbial pathways enriched in smokers were those implicated in polymer degradation and amino acid metabolism. The taxonomic and metabolic profile of the salivary microbiome in waterpipe smokers compared to healthy controls exhibited a paradigm shift, thus, implying an alteration in the homeostatic balance of the oral cavity posing unique challenges for oral health.

Reproductive outcomes of water pipe smoking: A scoping review

Objective: To present an overview of the adverse effects of water pipe smoking on various aspects of reproduction and perinatal complications, covering all the most relevant studies, from descriptive findings to clinical trials. Methods: We reviewed the literature and included full publications in English provided by international biomedical databases, including PubMed, Science Direct, EBSCO, Scopus, and Google Scholar, and Cochrane Library over the last 38 years (May 1985 to June 2023). Search terms (Water pipe, Narghile, Shisha, Dokha, etc., and Reproduction, Fertility, etc.) were adopted from Medical Subheading (MeSH) and Boolean operators were utilized to improve sensitivity. Results: 133 Papers were identified in the initial search, of which 29 were excluded due to duplication. Eliminating search overlap and irrelevant records by reviewing titles and abstracts reduced 42 papers. 62 Full-publication articles met the inclusion criteria. We summarized the effects of waterpipe smoke exposure on reproductive health based on three main categories: male and female fertility, fetal and neonatal outcomes, and pregnancy complications. Conclusions: Water pipe smoking has potential adverse effects on different aspects of human reproductive health, including semen parameters, male and female fertility, and fetal and neonatal health, and contributes to many maternal complications and morbidities.

Predicting thrombotic cardiovascular outcomes induced by waterpipe-associated chemicals using comparative toxicogenomic database: Genes, phenotypes, and pathways

Hookah, or waterpipe, is a tobacco smoking device that has gained popularity in the United States. A growing body of evidence demonstrates that waterpipe smoke (WPS) is associated with various adverse effects on human health, including infectious diseases, cancer, and cardiovascular diseases (CVDs), particularly thrombotic events. However, the molecular mechanisms through which WPS contributes to disease development remain unclear. In this study, we utilized an analytical approach based on the Comparative Toxicogenomics Database (CTD) to integrate chemical, gene, phenotype, and disease data to predict potential molecular mechanisms underlying the effects of WPS, based on its chemical and toxicant profile. Our analysis revealed that CVDs were among the top disease categories with regard to the number of curated interactions with WPS chemicals. We identified 5674 genes common between those modulated by WPS chemicals and traditional tobacco smoking. The CVDs with the most curated interactions with WPS chemicals were hypertension, atherosclerosis, and myocardial infarction, whereas “particulate matter”, “heavy metals”, and “nicotine” showed the highest number of curated interactions with CVDs. Our analysis predicted that the potential mechanisms underlying WPS-induced thrombotic diseases involve common phenotypes, such as inflammation, apoptosis, and cell proliferation, which are shared across all thrombotic diseases and the three aforementioned chemicals. In terms of enriched signaling pathways, we identified several, including chemokine and MAPK signaling, with particulate matter exhibiting the most statistically significant association with all 12 significant signaling pathways related to WPS chemicals. Collectively, our predictive comprehensive analysis provides evidence that WPS negatively impacts health and offers insights into the potential mechanisms through which it exerts these effects. This information should guide further research to explore and better understand the WPS and other tobacco product-related health consequences.

Abstract 223: Chronic exposure to waterpipe smoke elicits immunomodulatory and carcinogenic effects in the lung

Abstract Effects of waterpipe smoking on lung pathobiology and carcinogenesis remain sparse despite the worldwide emergence of this tobacco vector as a socially acceptable form of smoking, particularly among the youth. To address this gap, we investigated the effects of chronic waterpipe smoke (WPS) exposure on lung pathobiology, host immunity, and tumorigenesis using both an experimental animal model and an exploratory observational analysis of human waterpipe smokers and non-smokers. Mice exposed to increasing doses of WPS (once or five times per week for 20 weeks), through an exclusively devised exposure system for this study, were more prone to develop lung tumors compared to control-air exposed littermates. This effect was accompanied by various pro-tumor immune phenotypes, including increased IL-17A+ levels in T/B cells as well as elevated expression of the immune checkpoint PD-L1 and the pro-inflammatory cytokine IL-1β in myeloid cells. While flow cytometry analysis revealed increased CD4 and CD8 T cell infiltration in WPS-exposed mice, gene signatures of cytotoxic and expanded immune response were, conversely, decreased in animals exposed to heavy WPS relative to control air. Interestingly, mice heavily exposed to WPS exhibited increased expression of Tmprss4, Cd55, and Ace2, cell receptors and mediators of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) entry and, thus, COVID-19 pathogenesis. We also perform RNA-sequencing analysis of bronchial airway epithelial brushings of cancer-free waterpipe smokers and non-smokers undergoing diagnostic bronchoscopy. Transcriptomes of normal airway cells in waterpipe smokers, relative to waterpipe non-smokers, harbored gene programs that were associated with poor clinical outcomes in lung adenocarcinoma (LUAD) patients, alluding to a WPS-associated molecular injury, like that established in response to cigarette smoking. Overall, our analyses demonstrate immunomodulatory and carcinogenic effects of WPS on the murine and human lung. Our study also shows that WPS exposure leads to a field of injury that may be associated with increased risk for lung cancer. This study is unique for interrogating carcinogenic effects of chronic exposure to WPS with the longest, to our knowledge, follow-up time in vivo. Our findings accentuate the need for additional studies that can guide evidence-based policies to counteract shortfalls in public health control of waterpipe smoking.

Water Pipe Tobacco Smoking and Risk of Coronary Artery Disease: A Systematic Review and Meta-Analysis

Waterpipe smoking has become a vitally important public health issue in the world with a false assumption that it has a less harmful effect. The aim of this study was to systematically review the association between waterpipe tobacco smoking and the risk of coronary artery disease (CAD). Up to September 25, 2018, we electronically searched the PubMed, Embase, and ISI Web of Science with no time restriction. We included observational studies and excluded conference abstracts, editorials, case reports, case series, and reviews. With the fixed model effect, we conducted a meta-analysis to evaluate the association between waterpipe smoking and coronary artery disease. Heterogeneity among studies was assessed by the I2 square test. Publication bias was assessed by Egger test. P<0.05 was set as significant level. Among 248 paper records identified through a database search, 52 full texts were eligible for full text assessment whereas 49 papers were excluded. Additionally, three studies were eligible for meta-analysis, which involved 58,960 adults with 1334 in the water pipe smoker group. Risk of CAD was increased in water pipe smokers compared to individuals who had never smoked water pipe but the result did not reach a statistical significance (OR=1.18, 95% CI: 0.98-1.38, p=0.06). We found that heavy water pipe smoking (40 to 50 sessions of waterpipe smoking/year) was associated with CAD compared to lower smokers defined as less than 40 to 50 water pipe/year (OR=2.001, 95% CI: 1.13-2.87). Heavy Water pipe smoking was associated with coronary artery disease based on clinical findings. It seems very crucial to increase public awareness on adverse effects of water pipe smoking and its cessation in clinical setting.

Effect of Water-Pipe Smoking on the Normal Development of Zebrafish.

Background: Among all types of tobacco consumption, Water-Pipe Smoking (WPS) is the most widely used in the Middle East and second-most in several other countries. The effect of WPS on normal development is not yet fully understood, thus the aim of this study is to explore the acute toxicity effects of WPS extract on zebrafish larvae. Methods: In this study, we compared the effects of WPS smoke condensates at concentrations varying from 50 to 200 µg/mL on developmental, cardiac, and behavioural (neurotoxicity) functions. Gene expression patterns of cardiac biomarkers were also evaluated by RT-qPCR. Results: Exposing zebrafish embryos to 50, 100, 150 and 200 µg/mL WPS for three days did not affect the normal morphology of Zebrafish embryos, as the tail flicking, behavioural and locomotion assays did not show any change. However, WPS deregulated cardiac markers including atrial natriuretic peptide (ANP/NPPA) and brain natriuretic peptide (BNP/NPPB). Furthermore, it induced apoptosis in a dose-dependent manner. Conclusion: Our data demonstrate that WPS can significantly affect specific cardiac parameters during the normal development of zebrafish. Further investigations are necessary to elucidate the pathogenic outcome of WPS on different aspects of human life, including pregnancy.

Вредное влияние курения кальяна на сердечно-сосудистую систему

Курение кальяна является относительно новой, но актуальной проблемой медицины, поскольку в Украине, как и во всем мире, отмечается катастрофический рост его употребления. В структуре табакокурения, которое остается основным модифицируемым фактором сердечно-сосудистого риска, в последние годы произошли изменения с увеличением доли альтернативных табачных продуктов, среди которых кальян занимает второе место по частоте. Потребители воспринимают кальян как вид социальной активности и интересного времяпрепровождения, но недооценивают его вред для здоровья и способность вызывать зависимость. А общество более толерантно относится к употреблению альтернативных табачных продуктов, чем традиционных сигарет, в том числе молодежью. Хотя на сегодня существуют данные относительно связи курения кальяна с развитием артериальной гипертензии, ишемической болезни сердца, инфаркта миокарда, сердечной недостаточности и смертностью от этих причин. Целью данного обзора является оценка факторов, способствующих распространению курения кальяна, его эффектов на сердечно-сосудистую систему и возможностей прекращения курения.

A CURIOUS CASE OF GRANULOMATOUS INFLAMMATION OF THE LUNG

SESSION TITLE: Medical Student/Resident Tobacco Cessation and Prevention Posters SESSION TYPE: Med Student/Res Case Rep Postr PRESENTED ON: October 18-21, 2020 INTRODUCTION: Young patients may have a multitude of causes for incidental lung lesions. Granulomatous lung lesions are frequently associated with infections, less common causes such as toxin mediated and vasculitis should be ruled out. We present the case of a patient who presented with granulomatous nodules due to water pipe smoking (WPS). CASE PRESENTATION: 21 year-old female presented with chest pain and dyspnea. She reported a 3-year history of tobacco use in the form of WPS and a remote history of vaping. Chest x-ray revealed a right middle lobe infiltrate concerning for pneumonia which was treated with antibiotics. CT chest further characterized the lesion as a 4 cm mass with additional clusters of irregular sub-centimetre nodules with subcarinal and mediastinal lymphadenopathy (Fig 1). Bronchoscopy showed large endobronchial lesions and histology showed necrotizing granulomas with negative stains and cultures for fungal or tuberculosis or evidence of malignancy. lymph node biopsy tissue samples demonstrated necrotizing granulomas. The patient was subsequently discharged from the hospital for outpatient management with a brief course of corticosteroids and was lost to follow up thereafter. DISCUSSION: Our patient who presented with an incidental lung lesion on her radiographs was found to have granulomatous lung nodules on histology. Workup remained negative for common causes such as Fungal infections, Tuberculosis or malignancy and she was eventually presumed to have WPS induced granulomatous lung disease given her prolonged and recent exposure. WPS as a trend has been silently picking up among certain young adult populations in the West with some studies indicating usage rates as high as 46.4% among college students. Contents in water pipe smoke such as ultrafine particulate matter (PM), carcinogenic particles and heavy metals have been implicated in a host of lung pathologies ranging from emphysema to infections and even lung cancers. Granulomatous inflammation however remains an infrequent complication and the mechanism underlying this pathology has yet to be elucidated. Such a finding has only been reported once before by Dyal et al who described the case of a young female with bilateral granulomatous secondary to WPS who was treated successfully with steroids, suggesting a component of underlying inflammation. CONCLUSIONS: Detailed and updated review could help strengthen evidence for the truly disastrous effects of WPS on long term health of our young adults, and potentially support litigation for the ban on sale and use of these products, as was accomplished recently in case of E-cigarettes or vaping.

Water-Pipe Smoking Exposure Deregulates a Set of Genes Associated with Human Head and Neck Cancer Development and Prognosis.

Water-pipe smoking (WPS) is becoming the most popular form of tobacco use among the youth, especially in the Middle East, replacing cigarettes rapidly and becoming a major risk of tobacco addiction worldwide. Smoke from WPS contains similar toxins as those present in cigarette smoke and is linked directly with different types of cancers including lung and head and neck (HN) carcinomas. However, the underlying molecular pathways and/or target genes responsible for the carcinogenic process are still unknown. In this study, human normal oral epithelial (HNOE) cells, NanoString PanCancer Pathways panel of 770 gene transcripts and quantitative real-time polymerase chain reaction (qRT-PCR) analysis were applied to discover differentially expressed genes (DEG) modulated by WPS. In silico analysis was performed to analyze the impact of these genes in HN cancer patient’s biology and outcome. We found that WPS can induce the epithelial–mesenchymal transition (EMT: hallmark of cancer progression) of HNOE cells. More significantly, our analysis of NanoString revealed 23 genes deregulated under the effect of WPS, responsible for the modulation of cell cycle, proliferation, migration/invasion, apoptosis, signal transduction, and inflammatory response. Further analysis was performed using qRT-PCR of HNOE WPS-exposed and unexposed cells supported the reliability of our NanoString data. Moreover, we demonstrate those DEG to be upregulated in cancer compared with normal tissue. Using the Kaplan–Meier analysis, we observed a significant association between WPS-deregulated genes and relapse-free survival/overall survival in HN cancer patients. Our findings imply that WPS can modulate EMT as well as a set of genes that are directly involved in human HN carcinogenesis, thereby affecting HN cancer patients’ survival.

Effects of Waterpipe Tobacco Smoking on the Spirometric Profile of University Students in Palestine: A Cross-Sectional Study.

Background Waterpipe smoking in young individuals is increasing with limited studies addressing its respiratory health effects. The aim of the study was to determine the effect of waterpipe smoking on young adults' lung functions. Spirometric parameters were compared between waterpipe smokers and nonsmokers. Methods A comparative cross-sectional study of university students, including males and females, was conducted. An interviewer-administered questionnaire was used to record students' characteristics. The spirometry test was performed to assess students' lung functions; we recorded the forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, peak expiratory flow (PEF), and forced expiratory flow between 25 and 75% of FVC (FEF25–75%). Results A total of 300 apparently healthy students (150 waterpipe smokers and 150 nonsmokers) were included in the study. Waterpipe smokers showed significantly lower values in FEV1, FEV1/FVC ratio, PEF, and FEF25–75% compared to the nonsmoker group (P < 0.05 to P < 0.001). The subgroup analysis on female students (50 WP smokers and 50 nonsmokers) showed a significant decrease in FEV1/FVC ratio, PEF, and FEF25–75% parameters (P < 0.001). Conclusion Waterpipe smoking is associated with reduced spirometric parameters in healthy young adults with relatively limited smoking years.

Ameliorative Effect of Gum Acacia on Water Pipe Smoke ‐ Induced Testicular Impairment in Mice

We investigated some effects of water pipe smoke (WPS) exposure (30 min/day, for 30 days) in male mice, and the possible ameliorative of gum acacia (GA) coadministration thereon. Controls were exposed to air‐only (AE). Twenty‐four hours post last exposure, the levels of some plasma reproductive hormones, biochemical markers of inflammation, oxidative and nitrosative stress and testicular histopathology were assessed. The concentration of cotinine, the predominant metabolite of nicotine, was also measured in urine. WPS exposure induced a significant decreases in testosterone, estradiol, luteinizing hormone, and androgen binding protein. Inhibin B concentration was significantly increased. Plasma alkaline phosphatase, lipopolysaccharide binding protein, uric acid, and lactate dehydrogenase were all significantly increased following WPS exposure. In testicular homogenate, NF‐κB p65, Nrf2, interleukin‐1β, interleukin‐6, tumor necrosis factor –α, and transforming growth factor‐β1 were all significantly elevated after WPS exposure. WPS exposure decreased nitrite and total nitrite, glutathione reductase activity, and increased lipid peroxidation, cytochrome C, and 8‐Oxo‐2′‐deoxyguanosine. Histopathologically, there was slight reduction in the diameter of the seminiferous tubules with disorganized spermatogenesis. Cotinine concentration was significantly increased in the WPS‐exposed group compared with the control group. GA co‐administration mitigated the adverse actions of WPS measured. We conclude that daily exposure to WPS at the above dose induced damaging effects to the reproductive system in male mice, and that GA co‐administration mitigated the adverse actions of WPS measured.Support or Funding InformationSupported by a joint grant from Sultan Qaboos University and United Arab Emirates University (CL/SQU ‐ UAEU/18/01).

Water Pipe Smoking Affects Young Females and Males Differently with Some Effects on Immune System Cells, but None for C-reactive Protein, Thyroid Hormones, and Vitamin D.

Introduction:Water pipe smoking (WPS) is a major health threat leading to higher mortality, morbidity, and incidence of many diseases, such as inflammatory, respiratory and cardiovascular diseases; and cancers. This study aimed to determine the differences in the effects of WPS on the immune system, inflammatory markers, lipids, vitamin D, and thyroid hormones in female and male WP smokers, and compared to nonsmokers of both sexes. No other studies showed the differences between female and male WP smokers for the parameters investigated here, with the exception of the lipid profile.Methodology:The study was carried on 76 randomly chosen subjects (17 female and 17 male WP smokers, 21 female and 21 male nonsmokers) living in Saudi Arabia with an age range of 20–35 years. Blood samples were collected to determine the differential complete blood counts; lipid profiles; and C-reactive protein, triiodothyronine, thyroxine, and vitamin D concentrations.Results:Results showed no significant differences between female smokers and nonsmokers for all parameters. Male smokers had a significantly lower mean monocytes count and a significantly higher mean red blood cell count and hemoglobin concentration compared to male nonsmokers. Comparing females and males among smokers and nonsmokers separately, the only significant difference in the parameters that was not found in both comparisons was a significantly lower mean basophil count in female nonsmokers compared to male nonsmokers.Conclusion:It may be concluded that the effects of WPS were limited to males with immune cells and hematology minimally affected, and that females and males were affected differently by WPS.

Acute and long-term effects of water pipe smoking on the respiratory system: A narrative review

Tobacco use has become a global major health problem and a leading global cause of preventable death. Water pipe smoking epidemic is on the rise and is replacing cigarettes as the most popular method of tobacco use in many countries. In this narrative review, we aimed to summarize the acute and long-term effects of water pipe smoking on the respiratory system. A comprehensive literature search addressing these effects was conducted without date restrictions. Among the serious acute respiratory effects of water pipe smoking on the respiratory system that have been reported in in literature are acute eosinophilic pneumonia, acute carbon monoxide poisoning, increase in respiratory rate, transmission of infection, and acute deterioration in lung function. Among the long-term effects are the increased risk of lung cancer, chronic obstructive lung disease, asthma and asthma exacerbations, and long-term effects on lung function. The impact of water pipe smoking on the respiratory system and on human health in general deserves more attention from researchers and health policy makers.

Testicular Toxicity of Water Pipe Smoke Exposure in Mice and the Effect of Treatment with Nootkatone Thereon

There is a worldwide increase in the popularity of water pipe (shisha) tobacco smoking including in Europe and North America. However, little is known about the effects of water pipe smoke (WPS) exposure on male reproductivity. We have recently demonstrated that WPS exposure in mice induces testicular toxicity including inflammation and oxidative stress. Nootkatone, a sesquiterpenoid found in grapefruit, has antioxidant and anti-inflammatory effects. However, the possible protective effect of nootkatone on WPS-induced testicular toxicity has not been reported before. Here, we tested the effects of treatment of mice with nootkatone on WPS-induced testicular toxicity. Mice were exposed to normal air or WPS (30 minutes/day, for 30 days). Nootkatone (90 mg/kg) was given orally to mice by gavage, 1 h before WPS or air exposure. Nootkatone treatment significantly ameliorated the WPS-induced increase in plasma levels of inhibin, uric acid, and lactate dehydrogenase activity. Nootkatone also significantly mitigated the decrease in testosterone, androgen-binding protein, and estradiol concentrations in the plasma induced by WPS. In testicular homogenates, WPS exposure caused a decrease in the total nitric oxide level and an increase in the proinflammatory cytokine interleukin-1β level and oxidative stress markers including malondialdehyde, cytochrome C, and 8-Oxo-2′-deoxyguanosine. All the latter effects were significantly alleviated by nootkatone treatment. Moreover, in testicular homogenate, nootkatone inhibited the expression of nuclear factor-kappaB induced by WPS. Likewise, histological examination of mouse testes showed that nootkatone treatment ameliorated the deterioration of spermatogenesis induced by WPS exposure. We conclude that nootkatone ameliorated the WPS-induced testicular inflammation and oxidative stress and hormonal and spermatogenesis alterations.

Water‐pipe Smoke Negatively Distress Cardiovascular Biomarkers in Mice

Tobacco use is one of the main risk factors to cardiovascular diseases (CVDs) and atherosclerosis in particular. It was mis‐considered that water‐pipe smoking (WPS) is less harmful than cigarette smoking due to its flavor. Studies had shown that more than 100 million people smoke waterpipe daily. WPS contains several toxic materials such as: nicotine, carcinogens, tar, carbon monoxide and heavy metals. Thus, WPS is considered to be as one of the toxic environmental factors that should be investigated intensively. The aim of this study is to investigate the effect of WPS on several cardiovascular biological markers that may cause atherosclerosis in mice. The study also conducted to study the temporal effects of WPS on the atherosclerotic biomarkers upon short (2 weeks) and long‐term (8 weeks) exposures. Mice were exposed to WPS and heart homogenates were analyzed to elucidate the effects of WPS on matrix metalloproteinase (MMPs), endothelin‐1 (ET‐1) and, myeloperoxidase (MPO). Following protein estimation, enzyme‐linked immunosorbent assays were done to measure the levels of MMPs (isoforms 1, 3, and 9), MPO, and ET‐1 protein. Our data showed that acute exposure to WPS significantly enhances the levels of MMP‐3, MMP‐9, and MPO expressions (p&lt;0.05) compared to their corresponding control. However, the body was capable to compromise the levels for such parameters following continuous exposure for 8 weeks (p&gt;0.05). Additionally, we showed that the level of ET‐1 was significantly higher upon chronic exposure to WPS compared to both control and acute exposure groups (p&lt;0.05). In conclusion, WPS has a significant negative effect on cardiac health and the enhancement of the atherosclerotic biomarkers (MMP‐3 and 9, MPO, and ET‐1) might represent an early scavenger of compensatory efforts to maintain cardiac function after WP exposure.Support or Funding InformationThis project was supported by a grant from the Deanship of Research at Jordan University of Science and Technology (grant number 2015/249 to AR).This abstract is from the Experimental Biology 2019 Meeting.

The Effect of Waterpipe Smoking on DNA Integrity Among Youth in Jordan

Waterpipes have been used to smoke tobacco and other substances by the indigenous people of Africa and Asia for at least four centuries. Waterpipe smoking causes different genotoxic effects. The evaluation of chromosome aberrations (CAs) is one of the standard methods used for assessing the DNA damage in human subjects. The aim of this study was to determine whether waterpipe smoking increases the frequency of different types of CAs in the peripheral blood lymphocytes of young waterpipe smokers ( $$n=25$$ ) compared with non-smokers ( $$n=25$$ ) in Jordan. Twenty-five metaphases were scored and evaluated for chromosome breakage, fragment and gap for each individual. Chromosomal breakage ratios were detected to be $$2.53\pm 1$$ and $$0.576\pm 0.64$$ in the waterpipe smokers and non-smokers groups, respectively. The fragments ratios were $$2.19\pm 0.9$$ and $$0.72 \pm 0.05$$ , and the gaps ratios were $$2.15\pm 0.67$$ and $$0.6\pm 0.5$$ in the waterpipe smokers and non-smokers groups ( $$p <0.0001$$ ), respectively. The results of the study revealed a significant increase in the frequencies of different types of CAs in waterpipe smokers compered to non-smokers, suggesting that smoking a waterpipe may cause genotoxic effects.

Waterpipe tobacco smoke distresses cardiovascular biomarkers in mice: alterations in protein expression of metalloproteinases, endothelin and myeloperoxidase

Introduction: Tobacco use is a major risk factor of cardiovascular diseases (CVD) and atherosclerosis in particular. The use of waterpipe smoking (WPS) is increasing due to the misperception that it is less harmful than cigarette smoking due to its flavor and the use of water as a filter. Thus, research that investigates toxic effects of WPS is essential. The aim of this study was to investigate the effect of WPS on major cardiovascular biomarkers that may develop atherosclerosis in mice.Methods: BALB/c mice were exposed to WPS for either two weeks (acute exposure) or eight weeks (chronic exposure). Then, the heart tissue homogenates were analyzed to elucidate the effects of WPS on matrix metalloproteinase (MMPs: isoforms 1, 3, and 9), metallopeptidase inhibitor (TIMP1), endothelin-1 (ET-1) and myeloperoxidase (MPO) using ELISA technique.Results: Current data showed that acute exposure to WPS significantly enhanced the levels of MMP-3, MMP-9, and MPO (p < 0.05) compared to their corresponding control. However, the body was capable to restore the increased levels of these parameters following chronic exposure to WPS for 8 weeks (p > 0.05). Additionally, the levels of ET-1 were significantly higher upon chronic exposure to WPS compared to both control and acute exposure groups (p < 0.05).Conclusions: Waterpipe exposure has a significant negative effect on the cardiovascular system. The enhancement of the atherosclerotic biomarkers (MMP-3, MMP-9, MPO, and ET-1) might represent an early scavenger of compensatory efforts to maintain cardiovascular function after WPS exposure.
