Abstract
Head and neck cancers are highly prevalent in south-east Asia, primarily due to betel nut chewing. Arecoline, the primary alkaloid is highly carcinogenic; however its role in promoting tumorigenesis by disrupting junctional complexes and increasing risk of metastasis is not well delineated. Subsequently, the effects of low and high concentrations of arecoline on the stability of tight junctions and EMT induction were studied. A microarray analysis confirmed involvement of a MAPK component, JunD, in regulating tight junction-associated genes, specifically ZO-1. Results established that although arecoline-induced phosphorylation of JunD downregulated expression of ZO-1, JunD itself was modulated by the lncRNA-NEAT1 in presence of arecoline. Increased NEAT1 in tissues of HNSCC patients significantly correlated with poor disease prognosis. Here we show that NEAT1-JunD complex interacted with ZO-1 promoter in the nuclear compartment, downregulated expression of ZO-1 and destabilized tight junction assembly. Consequently, silencing NEAT1 in arecoline-exposed cells not only downregulated the expression of JunD and stabilized expression of ZO-1, but also reduced expression of the EMT markers, Slug and Snail, indicating its direct regulatory role in arecoline-mediated TJ disruption and disease progression.

Singh PK, Yadav A, Singh L, Mazumdar S, Sinha DN, Straif K, Singh S. Areca nut consumption with and without tobacco among the adult population: a nationally representative study from India. BMJ Open 2021; 11:e043987. [PMID: 34130957 PMCID: PMC8208015 DOI: 10.1136/bmjopen-2020-043987] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2020] [Accepted: 04/19/2021] [Indexed: 11/03/2022] Open
Abstract
OBJECTIVE Areca nut is one of the most widely consumed substances globally, after nicotine, ethanol and caffeine and classified as carcinogenic to humans. This study examines the disparity and determinants of areca nut consumption with and without tobacco in India. DESIGN Nationally representative cross-sectional study. PARTICIPANTS We used the nationally representative Global Adult Tobacco Survey 2016-2017. The analytical sample size was 74 037 individual's aged 15 years and above with a response rate of 92.9%. MEASURES Current consumption of areca nut without tobacco and with tobacco. METHOD We examined determinants of areca nut consumption (without tobacco and with tobacco) using multinomial logistic regression, accounting for the survey design. RESULTS About 23.9% (95% CI 23.1 to 24.8) of the adult population consume areca nut, that is, approximately 223.79 million people in India; majority of users (14.2%-95% CI 13.5 to 14.9) consumed areca nut with tobacco. When compared with women, men were more likely to consume areca nut (with tobacco relative risk (RR)=2.02; 95% CI 1.85 to 2.21 and without tobacco RR=1.13; 95% CI 1.07 to 1.20). Age, marital status, education, occupation, caste, religion and region were significantly associated with areca nut consumption. However, the direction and magnitude of association differ with respect to the areca nut consumption with and without tobacco. CONCLUSION The ongoing tobacco control efforts would not address the majority of areca nut users until greater attention to areca nut consumption with and without tobacco is reflected in health policies in India.

Abstract
BACKGROUND Betel quid is more widely consumed than tobacco in Myanmar. It brings adverse health effects regardless of whether it contains tobacco; however, Myanmar has no clear prevention strategy. This study aims to show a broader picture of the prevalence of betel quid chewing and the observable characteristics of its consumers in Myanmar by comparing it to tobacco usage. METHODS This study used the 2015-2016 Myanmar Demographic and Health Survey data. First, we identified characteristics of betel quid consumers by a logit model. Next, we focused on exploring who would be likely to become heavy users, conditioned on being a betel quid consumer by controlling for possible sample selection bias. RESULTS We found differences in characteristics for betel chewers and tobacco smokers, and for betel quid users and heavy users. CONCLUSION These results suggest that betel quid consumption should be regulated by a specific prevention strategy rather than by Myanmar's existing tobacco prevention strategy.

Abstract
BACKGROUND Video gaming (VG) has since the 1980s become increasingly ubiquitous entertainment among the adolescents and young adults. Many young people expe-rienced dizzy spells, but not vertiginous episodes, after playing VG. OBJECTIVES This study performed ocular vestibular-evoked myogenic potential (oVEMP) and cervical VEMP (cVEMP) tests in subjects before and after engaging on VG to investigate the effect of VG on the otolithic reflex system. METHODS Twenty subjects who frequently played VG (>3 days per week) for more than 10 years were assigned to the long-term group. Another 20 subjects with engaging on VG <3 days per week or <10 years were assigned to the short-term group. Each subject underwent baseline oVEMP and cVEMP tests first, followed by playing VG for 1 h. Then, all subjects underwent the same paradigm. The "VG-year" is defined as frequency of VG playing within 1 week (day/week) multiplied by total length of VG engagement (year). RESULTS Engagement on VG rarely affected the oVEMP responses for either short- or long-term players. In contrast, the response rates of cVEMP significantly declined from pre-VG period (80%) to post-VG period (58%) in the short-term group, but not in the long-term group. The cutoff value for predicting absent cVEMP in VG engagement is 21 VG-year. CONCLUSION Short-term engagement on VG may result in temporary cVEMP loss, while permanent cVEMP loss could be identified in long-term VG players. The cutoff value for predicting absent cVEMP in VG engagement is 21 VG-year, indicating that damage to the sacculo-collic reflex system could be anticipated in a subject who has played VG at least 1 h per session, 7 days weekly for 3 years.

Abstract
INTRODUCTION The youth are a vulnerable population-group for tobacco-related harms. Schools are an excellent setting for health promotion; yet there is a dearth of school-based cessation interventions, rarely evaluated for their impact. Here, we assess the impact of the LifeFirst program: an ongoing tobacco and supari (areca nut) cessation intervention delivered to students from corporation schools in Mumbai city. METHODS We used a prospective quasi-experimental design with an intervention and a control arm embedded within an ongoing LifeFirst program in select schools. We used a difference-in-difference analysis with baseline and end-line surveys to assess the program's impact on students' knowledge about harms, students' refusal skills, and prevalence of tobacco/supari use. We report our work using the TREND statement checklist. RESULTS A total of 959 students registered in the LifeFirst program. In our analysis, we included 827 students who completed both the baseline and end-line surveys. Postintervention, we found both tobacco and supari use reduced substantially among the intervention group while tobacco use increased among the control group. The difference-in-difference estimates show a statistically significant reduction of 17.9 and 38.1 percentage points in the intervention group for tobacco and supari use respectively, beyond the reduction in the control group. CONCLUSIONS The LifeFirst program was successful in reducing tobacco and supari use among the study participants and protected students in the intervention group against new uptake of tobacco. It helped improve knowledge score and refusal skills among students. Implementation and evaluation of similar school-based programs should be considered as part of a multi-strategy approach to reducing tobacco use among young people.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18084020. [PMID: 33921213 PMCID: PMC8069503 DOI: 10.3390/ijerph18084020] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/08/2021] [Revised: 04/06/2021] [Accepted: 04/08/2021] [Indexed: 01/08/2023]
Abstract
Objectives: Increased triglyceride glucose (TyG) index appears to be linked to carotid and coronary atherosclerosis and calcifications and possesses an elevated future risk of developing cardiovascular disease. Corrected QT (QTc) interval prolongation is associated with ventricular arrhythmias and sudden cardiac death, and a high prevalence of prolonged QTc interval was previously reported in blue-collar workers. The purpose of this study was to find the possible causal inter-relationship between TyG index and QTc interval in a large population of Chinese male steelworkers. Methods: A total of 3189 male workers from two steel plants were enrolled. They responded to a cross-sectional questionnaire on basic attributes and lifestyle, including sleep patterns. All workers in the two plants underwent periodic health checkups, including twelve-lead electrocardiography. Structural equation modeling (SEM) was used to assess the direct and indirect effects of TyG index on QTc interval. Results: With increasing TyG index tertile, the male steelworkers had an increased QTc interval. Applying multivariate analysis, TyG index was associated independently with the odds of QTc prolongation (adjusted odds ratio = 2.73, 95% confidence interval = 1.39–5.24, p = 0.004). SEM revealed that TyG index, hypertension, obesity, lifestyle, white blood cell (WBC) count, and liver function had statistically significant direct effects on QTc interval. Furthermore, TyG index also had an indirect effect on QTc interval through hypertension, obesity, WBC count, and liver function. Moreover, lifestyle had an indirect effect on QTc interval through TyG index. The final model explained 14% of the variability in QTc interval. Conclusions: An increased TyG index was associated with QTc interval prolongation in this study, and SEM delineated possible causal pathways and inter-relationships of the risk factors contributing to the occurrence of QTc prolongation among Chinese male steelworkers.

Abstract
INTRODUCTION Areca nut, commonly known as supari, is widely used in India. In addition to tobacco and alcohol, it has been identified as one of the contributory factors for high rates of oral cancer in the country. METHODS This qualitative study explored perceptions and practices around the use of areca nut by conducting in-depth interviews and focus group discussions with 61 school-going adolescents in the city of Mumbai, India. RESULTS Respondents used low-priced sachets of sweetened, flavored areca nut called supari. They perceived supari as harmless because it was sweet, it had a fresh after-taste as compared to bitter-tasting smokeless tobacco products. How can something sweet be harmful was a common argument offered by respondents. Respondents invariably compared and contrasted areca nut to more harmful and addictive tobacco products; perceiving supari to have milder or inconsequential health effects. Supari use was initiated with friends, a sibling, or a cousin. It was almost always used with friends. Respondents also reported difficulty in refusal to use when offered supari by friends. Parental response to finding out about the child's supari use was often muted in comparison to extreme reactions associated with the child's tobacco use. CONCLUSIONS Perceptions of low risk or relative harmlessness of the product, social influence, and the features of the product itself influence adolescents' use of areca nut. Although more research on perceptions of risk, with larger samples, is required, these findings are useful for school-based tobacco prevention and cessation programs and health policy-makers. IMPLICATIONS The study findings have implications for prevention and cessation programs, and policymakers. School-based health education programs should allocate special sessions on areca nut use. Focused mass media communication campaigns describing its harms and association with oral cancer are required for the larger community. As was done for tobacco, Indian policymakers will have to evaluate the marketing, commerce, and distribution of areca nut and create appropriate laws. More research, with larger nationwide samples, is required to examine perceptions of areca nut.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most common diseases. It mainly causes the stomach contents to flow back to the esophagus, thereby stimulating the esophagus and causing discomfort. From the results of our research, we intend to provide the general public with information related to preventing gastroesophageal reflux disease and medical personnel with information on the treatment and care of patients with gastroesophageal reflux disease. This study aimed to investigate the association of lifestyle habits and perceived symptoms on GERD in patients who underwent routine health check-ups. This study was conducted as a retrospective cross-sectional design to collect GERD cases from the medical records containing the health questionnaires and the report of endoscopic findings on the day of the health check-up. A total of 5653 patients were enrolled between 1 January 2016, and 31 December 2018. About 60.2% (n = 3404) of patients with GERD were diagnosed based on endoscopic findings. Descriptive and multivariate logistic regression analyses were performed to identify the risk factors of the development of GERD. The results of the multivariate logistic regression analysis showed that age, sex, waist circumference, Areca catechu chewing habit, sleep disorders, otolaryngology symptoms, and hepatobiliary and gastrointestinal symptoms were significantly associated with GERD. In this study, our results can be used as a reference for public health care and clinicians. Because most GERD cases can be controlled and prevented by lifestyle modifications, health professionals should always obtain a detailed history regarding symptoms and lifestyle habits associated with GERD.

Abstract
Although several studies have reported the multiple systemic effects of betel nut (BN) chewing, analyses performed on the colonic system have been few. To analyze the association between BN chewing and diverticulosis, we conducted a cross-sectional study of 5,586 eligible participants who underwent colonoscopy at a medical center in Taiwan from 2010 to 2016. BN chewing was recorded based on an assessment of personal history. Diverticulosis was categorized based on whether colonoscopies had been performed during health examinations by trained physicians at Tri-Service General Hospital. The association between different exposures, including cigarette, alcohol, BN, and diverticulosis, was also analyzed. Our study included 3,161 males and 2,425 females, and males have significantly higher prevalence rates of BN chewing than females (11.1% versus 0.3%, respectively). In the male group, BN chewing had an adjusted odd ratio (OR): 1.65(95% confident interval (CI): 1.12–2.44) with the presence of diverticulosis. Among the combination of exposures of cigarette, alcohol, and BN, the group with BN chewing combined with smoking and drinking showed significant association between diverticulosis with adjusted OR: 1.909 (95% CI, 1.188–3.065). Further subgroup analysis displayed adjusted OR: 2.310 (95% CI, 1.245–4.287) in obesity and OR: 2.406 (95% CI, 1.205–4.803) in elderly male. Thus, BN chewing is independently associated with diverticulosis in male.

Which Factors, Smoking, Drinking Alcohol, Betel Quid Chewing, or Underlying Diseases, Are More Likely to Influence the Severity of COVID-19? Front Physiol 2021; 11:623498. [PMID: 33536941 PMCID: PMC7849623 DOI: 10.3389/fphys.2020.623498] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Accepted: 12/22/2020] [Indexed: 01/08/2023] Open
Abstract
The global outbreak of the coronavirus disease 2019 (COVID-19) pandemic occurred in late 2019 and early 2020. The factors that influence disease severity should be of clinical concern. Existing findings on the effects of smoking on COVID-19 are also controversial and need to be confirmed by further research. In addition, the effects of alcohol consumption and betel quid (BQ) chewing on COVID-19 are unclear. The aim of this study was to examine the demographic characteristics of COVID-19 patients and the effects of smoking, drinking, BQ chewing, and underlying diseases on the severity of COVID-19. A retrospective study was conducted on 91 patients with confirmed cases of COVID-19 hospitalized in Yueyang, Hunan Province, China from 21 January to 8 March, 2020. Patient demographic data, and information on smoking, drinking and BQ chewing, and underlying diseases were extracted from the patient electronic medical records (EMR) and telephone interviews. The chi-square test was used to conduct a univariate analysis of the factors influencing the severity of COVID-19, and ordinal logistic regression analysis was used to identify the factors related to the severity of COVID-19. The results showed that the rates of smoking, drinking and BQ chewing were 15.4, 26.4, and 7.1%, respectively, there was no significant relationship between these lifestyle factors and the severity of COVID-19 (P > 0.05). However, underlying diseases such as diabetes [odds ratio (OR) = 7.740, 95% confidence interval (CI):1.000-60.740, P = 0.050], source of infection (OR = 0.180, 95% CI: 0.030-0.980, P = 0.049), and employment status (retired/unemployed vs. employed: OR = 29.430, 95% CI, 1.050 - 822.330, P = 0.047) were significant independent predictors of severe COVID-19 infection. These individuals should be informed of methods to increase personal protection, and doctors should prevent these individuals from developing serious diseases. It is important to pay attention to the source of infection and timely medical treatment. This study showed that the clinical classification of COVID-19 was associated with patients with diabetes, source of infection, and retired/unemployed. Therefore in the clinical practice of COVID-19 should be more concern these factors. Although no statistical significance was found in smoking, drinking alcohol, BQ chewing, and severity of COVID-19 patients, more studies have confirmed that are harmful and risk factors for underlying diseases in the population. Health authorities should formulate policies to publicize the harmful effects of smoking, drinking, and betel nut chewing and promote a healthy lifestyle.

Abstract
This study aimed to increase workers' awareness of betel quid cessation. Methods: Using community and workplace resources, a workplace health promotion program was developed in accordance with the five action areas of the Ottawa Charter. Questionnaires were administered to examine the changes in the knowledge and attitudes of 714 workers in different occupations before and three months after the intervention. Results: Regardless of subjects' pre-intervention chewing status, their knowledge and attitude scores relating to betel quid cessation increased significantly after the intervention. The effect of occupation was significant on the post-intervention knowledge and attitude scores among chewers. Furthermore, 16 (11.6%) of the 138 study subjects who chewed betel quid before the intervention and had no willingness to quit, did quit betel quid chewing following the intervention. The factors contributing to an unwillingness to quit among chewers with no intention to quit before the intervention were examined. Workers in the electronic material manufacturing industry had a greater willingness to quit compared to those in the metal, machinery, and related trades (odds ratio [OR] = 0.15; 95% confidence interval [CI] = 0.02-0.94). Travel attendants, tour guides, cleaners, and helpers were the least willing to quit (OR = 21.29; 95% CI = 2.51-180.81). Conclusions: This study promoted workers' awareness of betel quid cessation by adopting the five action areas of the Ottawa Charter framework, the effectiveness of the intervention varied in different occupations. Workers with a high-income and better education level had a higher awareness of betel quid cessation.

Subst Use Misuse 2021; 56:2017-2025. [PMID: 34396897 DOI: 10.1080/10826084.2021.1963990] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 10/20/2022]
Abstract
Areca-nut (AN) and added smokeless-tobacco (SLT) are considered agents that may cause addiction to betel-quid (BQ). However, the primary addictive substance in AN is not clearly understood. Objective: The present review evaluates possible addictive chemicals in AN with their mechanisms of action for progression to BQ dependence, as it is essential to overcome barriers in BQ cessation. It also identifies innovative treatment modalities in BQ cessation including the scope for research on pharmacotherapy using Monoamine-oxidase Inhibitors, Selective Serotonin Re-uptake Inhibitors and Norepinephrine Dopamine Reuptake Inhibitors. Methods: This is a narrative review on addictive properties of BQ and trials undertaken to promote cessation of SLT or AN use. Results: Twenty interventional studies, three by behavioral therapy and seventeen using pharmacotherapy were reviewed. There was heterogeneity in reported follow up times, most studies reporting data at 12 weeks with abstinence rates of 45-55% for SLT cessation and at 8 weeks with abstinence rates around 35% for AN cessation. Conclusion: Even though literature reveals a few cessation programs through behavioral support for BQ addiction, its success has been limited in certain instances mainly due to addictive properties of AN, resulting in withdrawal and relapse. Hence, in line with pharmacotherapy in tobacco smoking cessation, potential pharmacological agents to assist in cessation of SLT and AN require more attention. Several clinical trials for SLT cessation have been carried out with varying levels of success using Nicotine Replacement Therapy and Varenicline while trials on antidepressants for SLT and AN cessation are also emerging.

Abstract
Areca nut (AN) is consumed by more than 600 million of individuals, particularly in some regions of South Asia, East Africa, and tropical Pacific, being classified as carcinogenic to humans. The most popular way of exposure consists of chewing a mixture of AN with betel leaf, slaked lime, and other ingredients that may also contain tobacco named betel quid (BQ). Arecoline is the principal active compound of AN, and, therefore, has been systematically studied over the years in several in vitro and in vivo genotoxicity endpoints. However, much of this information is dispersed, justifying the interest of an updated and comprehensive review article on this topic. In this sense, it is thus pertinent to describe and integrate the genetic toxicology data available as well as to address key toxicokinetics aspects of arecoline. This review also provides information on the effects induced by arecoline metabolites and related compounds, including other major AN alkaloids and nitrosation derivatives. The complexity of the chemicals involved renders this issue a challenge in genetic toxicology. Overall, positive results in several endpoints have been reported, some of them suggesting a key role for arecoline metabolites. Nevertheless, some negative genotoxicity findings for this alkaloid in short-term assays have also been reported in the literature. Finally, this article also collates information on the potential mechanisms of arecoline-induced genotoxicity, and suggests further approaches to tackle this important toxicological issue.

Betel-Quid Chewing, Heart Failure, and Premature Ventricular Contractions in Patients with Cardiopulmonary Symptoms. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17207472. [PMID: 33066687 PMCID: PMC7602392 DOI: 10.3390/ijerph17207472] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 10/03/2020] [Accepted: 10/12/2020] [Indexed: 11/17/2022]
Abstract
Betel-quid (BQ) is a commonly used psychoactive substance that renders a specific cardiotoxicity. The purpose of this study was to investigate the association between BQ chewing and premature ventricular contractions (PVC) in patients with cardiopulmonary symptoms, and examine the potential influences of cardiovascular and chronic diseases on such relationship. Participants were 146 patients with cardiopulmonary symptoms who participated in 24-h Holter electrocardiogram monitoring during 2012–2018 in a hospital serving residents that lived in a BQ high prevalence area. Data on substance uses and medical histories for cardiovascular and chronic diseases were collected. Baron–Kenny method was employed to evaluate possible mediation. In patients with cardiopulmonary symptoms, 36.3% were BQ users and 63.7% were nonusers. Adjusting for covariates, BQ chewing was significantly associated with heart failure and diabetes mellitus (adjusted odds ratio (aOR) = 3.4 and 2.3, respectively), but only heart failure was significantly correlated with a low and high level of PVC. Additionally controlling for the effect of heart failure, the risk of high PVC for BQ users reduced from 3.60 to 2.88; however, the risk for BQ chewers remained significant (95% CI: 1.06–7.84). Heart failure was found to explain 27.7% of the excessive effect of BQ use on high PVC. In conclusion, BQ use is directly associated with an elevated risk of high PVC in patients with cardiopulmonary symptoms. The higher risk might be elevated among patients who suffered heart failure. Given several research limitations, the findings from this study offer future opportunities for validation.

Abstract
Sexual enhancers increase sexual potency, sexual pleasure, or libido. Substances increasing libido alter the concentrations of specific neurotransmitters or sex hormones in the central nervous system. Interestingly, the same pathways are involved in the mechanisms underlying many psychiatric and neurological disorders, and adverse reactions associated with the use of aphrodisiacs are strongly expected. However, sexual enhancers of plant origin have gained popularity over recent years, as natural substances are often regarded as a safer alternative to modern medications and are easily acquired without prescription. We reviewed the psychiatric and neurological adverse effects associated with the consumption of herbal aphrodisiacs Areca catechu L., Argemone Mexicana L., Citrus aurantium L., Eurycoma longifolia Jack., Lepidium meyenii Walp., Mitragyna speciosa Korth., Panax ginseng C. A. Mey, Panax quinquefolius L., Pausinystalia johimbe (K. Schum.) Pierre ex Beille, Piper methysticum G. Forst., Ptychopetalum olacoides Benth., Sceletium tortuosum (L.) N. E. Brown, Turnera diffusa Willd. ex. Schult., Voacanga africana Stapf ex Scott-Elliot, and Withania somnifera (L.) Dunal. A literature search was conducted on the PubMed, Scopus, and Web of Science databases with the aim of identifying all the relevant articles published on the issue up to June 2020. Most of the selected sexual enhancers appeared to be safe at therapeutic doses, although mild to severe adverse effects may occur in cases of overdosing or self-medication with unstandardized products. Drug interactions are more concerning, considering that herbal aphrodisiacs are likely used together with other plant extracts and/or pharmaceuticals. However, few data are available on the side effects of several plants included in this review, and more clinical studies with controlled administrations should be conducted to address this issue.

Betel Quid Health Risks of Insulin Resistance Diseases in Poor Young South Asian Native and Immigrant Populations.

Abstract
Betel quid, traditionally prepared with areca nut, betel leaf, and slaked lime, has been consumed for thousands of years, mainly in the form of chewing. Originally used for cultural, medicinal, and ceremonial purposes mainly in South Asian countries, its use has recently spread across the globe due to its psychoactive, euphoric, and aphrodisiac properties. Now it is widely used as a social lubricant and source of financial profit. Unfortunately, the profit motive has led to high rates of habitual consumption with eventual conversion to addiction among young girls and boys. Moreover, the worrisome practice of including tobacco in quid preparations has grown, particularly among pregnant women. Major health concerns include increased rates of malignancy, oral pathology, and cardiovascular, hepatic, fertility, metabolic, and neuropsychiatric disorders. Metabolic disorders and insulin resistance disease states such as type 2 diabetes, obesity, and metabolic syndrome contribute to cognitive decline and neurodegeneration. Mechanistically, the constituents of areca nut/betel quid are metabolized to N-nitroso compounds, i.e., nitrosamines, which are carcinogenic at high doses and cause insulin resistance following chronic low-level exposures. From an epidemiological perspective, the rising tide of insulin resistance diseases including obesity, diabetes, and dementias that now disproportionately burden poor countries has been propagated by rapid commercialization and enhanced access to betel quid. Public health measures are needed to impose socially and ethically responsible barriers to yet another cause of global health disparity.

Abstract
OBJECTIVES Arecoline is the main bioactive substance extracted from Areca catechu L, which has cell, neural and genetic toxicity. The function of arecoline in reproductive system has not been well explored. MATERIALS AND METHODS To investigate the toxic effects of arecoline on oocyte development, immunofluorescence staining, qPCR, Western blotting, sperm binding assays and in vitro fertilization were performed to evaluate oocyte meiosis competence and embryo development. RESULTS Our data revealed that arecoline exposure disrupts actin filament dynamics, spindle assembly and kinetochore-microtubule attachment stability in mouse oocytes, leading to aneuploidy and oocyte meiosis arrest. In addition, arecoline treatment disturbs the distribution of mitochondria, reduces ATP production and increases the level of oxidative stress, which ultimately induces oocyte apoptosis. Supplementation with metformin, a medicine for type 2 diabetes in the clinic, partially alleviates these damages. CONCLUSIONS Metformin has a protective effect on arecoline-induced mouse oocytes apoptosis.

Abstract
Background Bougainville, an autonomous region of Papua New Guinea (PNG) is slowly improving services and infrastructure destroyed 20 years ago during the ten year civil war. However, the region still faces significant constraints to economic growth and human development and remains under-developed compared to PNG and close Pacific neighbours. PNG's 2017 Human Development Category (HDC) was one of the lowest at 0.544. The Bougainville Strategic Development Plan 2018–2022 noted significant gaps in health services and infrastructure, had inadequate water and waste disposal and experienced weak markets and cocoa quality. This research examines domestic conditions and the extent to which they impact on livelihoods. Method A cross-sectional livelihood survey was administered to cocoa growing households in 33 Village Assemblies (VAs) with 11 VAs in each of the three regions. Results Data was collected from 5172 individuals. A significant majority of households reported multiple health issues, rudimentary housing, unimproved sanitation and unimproved water. Over two-thirds of cocoa growers did not sell any cocoa bags in 2014–2016 resulting in low incomes and greater food insecurity compared to families selling cocoa. Families that produced no saleable cocoa were more likely to have rudimentary housing, unimproved toilet facilities and unsafe water, factors that increase the likelihood of chronic disease and exacerbate malnutrition and poor labour productivity. Conclusion This study provides key information about the health and livelihood status of cocoa growers in Bougainville. If productivity is to increase, farmer health needs to improve including improving water and sanitation practices and diets. Building a responsive health system for the community is a challenge when a majority of the population live in small villages with difficult access to health centres. Establishing and integrating outreach village health clinics will enable health care to be more accessible to these remote communities. Cocoa productivity in Bougainville remains low. There are major constraints improved livelihoods for cocoa farmers. Many households are food insecure with unimproved water and sanitation. An accumulation of conditions may limit capacity to sell cocoa. A One Health approach can identify and address many factors impacting cocoa farmers livelihoods.

Glutathione S-transferasesP1 AA (105Ile) allele increases oral cancer risk, interacts strongly with c-Jun Kinase and weakly detoxifies areca-nut metabolites. Sci Rep 2020; 10:6032. [PMID: 32265484 PMCID: PMC7138809 DOI: 10.1038/s41598-020-63034-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 03/19/2020] [Indexed: 11/21/2022] Open
Abstract
The Glutathione S-transferases (GSTs) protects cellular DNA against oxidative damage. The role of GSTP1 polymorphism (A313G; Ile105Val) as a susceptibility factor in oral cancer was evaluated in a hospital-based case-control study in North-East India, because the habit of chewing raw areca-nut (RAN) with/without tobacco is common in this region. Genetic polymorphism was investigated by genotyping 445 cases and 444 controls. Individuals with the GSTP1 AA-genotype showed association with the oral cancer (OR = 3.1, 95% CI = 2.4–4.2, p = 0.0002). Even after adjusting for age, sex and habit the AA-genotype is found to be significantly associated with oral cancer (OR = 2.4, 95% CI = 1.7–3.2, p = 0.0001). A protein-protein docking analysis demonstrated that in the GG-genotype the binding geometry between c-Jun Kinase and GSTP1 was disrupted. It was validated by immunohistochemistry in human samples, showing lower c-Jun-phosphorylation and down-regulation of pro-apoptotic genes in normal oral epithelial cells with the AA-genotype. In silico docking revealed that AA-genotype weakly detoxifies the RAN/tobacco metabolites. In addition, experiments revealed a higher level of 8-Oxo-2′-deoxyguanosine induction in tumor samples with the AA-genotype. Thus, habit of using RAN/tobacco and GSTP1 AA-genotype together play a significant role in predisposition to oral cancer risk by showing higher DNA-lesions and lower c-Jun phosphorylation that may inhibit apoptosis.

Abstract
The family Arecaceae includes 181 genera and 2,600 species with a high diversity in physical characteristics. Areca plants, commonly palms, which are able to grow in nearly every type of habitat, prefer tropical and subtropical climates. The most studied species Areca catechu L. contains phytochemicals as phenolics and alkaloids with biological properties. The phenolics are mainly distributed in roots followed by fresh unripe fruits, leaves, spikes, and veins, while the contents of alkaloids are in the order of roots, fresh unripe fruits, spikes, leaves, and veins. This species has been reputed to provide health effects on the cardiovascular, respiratory, nervous, metabolic, gastrointestinal, and reproductive systems. However, in many developing countries, quid from this species has been associated with side effects, which include the destruction of the teeth, impairment of oral hygiene, bronchial asthma, or oral cancer. Despite these side effects, which are also mentioned in this work, the present review collects the main results of biological properties of the phytochemicals in A. catechu. This study emphasizes the in vitro and in vivo antioxidant, antimicrobial, anticancer, and clinical effectiveness in humans. In this sense, A. catechu have demonstrated effectiveness in several reports through in vitro and in vivo experiments on disorders such as antimicrobial, antioxidant, or anticancer. Moreover, our findings demonstrate that this species presents clinical effectiveness on neurological disorders. Hence, A. catechu extracts could be used as a bioactive ingredient for functional food, nutraceuticals, or cosmeceuticals. However, further studies, especially extensive and comprehensive clinical trials, are recommended for the use of Areca in the treatment of diseases.

[PMID: 32154430 PMCID: PMC7052403 DOI: 10.1016/j.conctc.2020.100544] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2019] [Revised: 01/28/2020] [Accepted: 02/16/2020] [Indexed: 11/29/2022] Open
Abstract
Background Areca nut (AN) is the seed endosperm of the Areca catechu L. palm and a Group 1 carcinogen chewed by 10–20% of the world population. AN is often chewed with Piper betle L. leaf, slaked lime, and tobacco to form a betel quid (BQ). The negative health effects associated with AN/BQ consumption warrant the need for an evidence-based cessation program. However, systematic research on AN/BQ cessation is rare. Methods/design The Betel Nut Intervention Trial (BENIT; trial #NCT02942745) is a randomized controlled trial designed to test the efficacy of an intensive AN/BQ cessation program. The trial is ongoing in Guam and Saipan with adult chewers who include tobacco in their BQ. Enrolled participants are assessed for their primary (chewing status) and secondary (saliva bio-verification) outcome at baseline, 22 days, and 6 months. Participants randomized into the control arm receive an educational booklet while those randomized into the intervention arm receive the educational booklet and a 22-day cessation program modeled after a smoking cessation program and led by trained facilitators. Information on chewing behavior (history, reasons for chewing, and AN/BQ composition and dependency) are collected. The intervention effectiveness is assessed using the logistic mixed model to compare cessation status between randomization groups. Discussion AN/BQ chewing affects a large population of people, many of whom live in low and moderate income countries in the Asia-Pacific region. Although the BENIT focuses on chewers in Guam and Saipan, it has the potential for greater regional and global importance.

Abstract
Oral Submucous fibrosis (OSMF) has traditionally been described as "a chronic, insidious, scarring disease of the oral cavity, often with involvement of the pharynx and the upper esophagus". Millions of individuals are affected, especially in South and South East Asian countries. The main risk factor is areca nut chewing. Due to its high morbidity and high malignant transformation rate, constant efforts have been made to develop effective management. Despite this, there have been no significant improvements in prognosis for decades. This expert opinion paper updates the literature and provides a critique of diagnostic and therapeutic pitfalls common in developing countries and of deficiencies in management. An inter-professional model is proposed to avoid these pitfalls and to reduce these deficiencies.

Abstract
Background: Betel nut chewing is a public health concern in the Asia-Pacific region and is an emerging issue in Vanuatu. Despite the significant health risks associated with betel nut chewing, few interventions have been undertaken to reduce its harm. Objectives: To investigate betel nut use in Vanuatu and to identify opportunities to reduce its harm and possible interventions, framing the responses using the World Health Organization's MPOWER tobacco control model. Method: Qualitative research design, in the form of semi-structured interviews with ten participants with expertise in health, agriculture, education or non-communicable disease in Port Vila, Vanuatu during June 2017. Recorded interviews were transcribed verbatim, and a general inductive approach was used to identify key themes. Results: Participants reported a recent increase in betel nut use in Vanuatu due to the influence from Papua New Guinea and the Solomon Islands. To reduce the harm of betel nut use in Vanuatu, participants suggested policies and strategies that aligned with the MPOWER framework that could be adopted for betel nut control, including restricting cultivation and sale of betel nut in Vanuatu and using radio and existing community networks to reach people with messages about the dangers of betel nut use. Conclusion: Betel nut use may be growing in popularity in Vanuatu, where there are potential policy options to minimize harm. The MPOWER model for tobacco control may be a useful framework to help the Vanuatu government to deliver a comprehensive approach to reducing harm from betel nut use.

Abstract
Background: Betel nut is used by an estimated 600 million people globally and is the 4th most widely used psychoactive substance in the world. Its use has been shown to cause oral and esophageal cancers. Therefore, cessation programs are needed in which an effective biomarker can be employed. Objectives: Buccal cells are highly exposed to the betel nut during its use and are also easy to collect. However, it is unknown if there are significant changes to these cells upon exposure or how long any changes may last as the turnover of buccal cells is relatively fast. We sought to determine if optical changes could be detected on buccal cells after exposure to betel nut and if detected, how long these changes were sustained. Methods: Flow cytometry was employed to determine whether fluorescence intensities differ between buccal cells exposed to betel nut and naïve cells. We further characterized the optical signature of buccal cells exposed to betel nut and other polyphenol-rich substances using lambda scans performed on a laser scanning confocal microscope. Results: We demonstrate that the fluorescence of betel nut exposed cells is greater than that of cells exposed to other optically active compounds such as polyphenol-rich foods. We also demonstrate that the fluorescence spectra of betel nut quid exposed cells are distinct from that of cells exposed to other polyphenol-rich substances. Conclusions: We conclude that detecting the altered fluorescence of buccal cells following exposure to betel nut quid may serve as a candidate biomarker for betel nut quid use.

Abstract
Background: While the patterns of consumption of areca nut and its by-products (ANBP) vary across South Asia and the rest of the world, all users share the probable severe outcome of oral submucous fibrosis (OSMF), and this is well reported. The role of psychosocial drivers of habit initiation and addiction is reported less. Objective: To reveal the burden of ANBP abuse, exploring the psychosocial relationship between sex, age at first exposure (AFE), the reason for initiation (RFI) with the type of habit (TOH). Methodology: Data came from the prospective hospital-based study conducted at K.M. Shah Dental College and Hospital covering years 2017 and 2018. Patients with oral lesions were assessed with complete history recording demographics, TOH, AFE, RFI, duration of habit, and clinical diagnosis of any oral and systemic diseases. Patients with a history of scleroderma, facial burns, and oral malignancy were excluded. Results: Of the 13,874 patients, 9.89% reported ANBP. We included 1000 OSMF patients. The mean age of the study cohort was 38.97 ± 14.29 years, with a range of 17-75 years. Males constituted the majority (80.1%). The most common TOH reported was regular use of gutkha (60.1%) followed by mawa (31.4%) with tension and stress (30.3%) being the most common RFI among the cohort. TOH was notably different in relation to AFE. Interestingly, mawa chewing (38.69%) was observed more in females. Importance: This study reveals the burden of ANBP abuse and reports the complex psychosocial relationships between sex, AFE, and RFI with TOH in OSMF patients in this high incidence population.

Abstract
Background: Betel nut use is a public health issue in the Asia-Pacific region that is often neglected. To control betel nut use, understanding of the adverse effects of betel nut use and evidence-based policies and strategies is necessary. Objectives: This narrative review aims to characterize the current situation on betel nut use at a global level regarding the epidemiology, pharmacology and toxicology, health effects, treatment options, policies and strategies. Methods: We found 139 existing literature published between 1970-2019 on the Web of Science database and other technical documents to collate the most relevant information on betel nut use. Data were categorized into appropriate themes. Results: The literature demonstrates that there is a lack of up to date statistics on betel nut use. There is limited research on the effect of policies and strategies to control betel nut use. Conclusion: Betel nut-chewing countries should focus on understanding which populations chew betel nut and implement appropriate policies, educational and cessation programs to help control betel nut use.

Abstract
Background: Research suggests that young working students are at higher risk for substance use. However, most studies have focused on students from middle-class families, with few investigations conducted on substance use by students from low-income families. Objective: To examine the associations between work experience and betel nut, alcohol, or tobacco (BAT) use among Taiwanese students from low-income families. Methods: The data for this cross-sectional study were derived from the fourth wave of the Taiwan Panel Study of Children and Youth survey which provides primary data on low-income families. A total of 3,350 low-income students aged 12-25 years old from middle school to university participated. The χ2 test was performed to examine differences in sociodemographic characteristics and BAT use between employed and unemployed students. Multivariate logistic regression was used to examine the associations between work status, work intensity, monthly income, occupation, and BAT use. Results: Employed students displayed higher BAT use than those who were unemployed. Increased BAT use was also associated with higher work intensity (except for betel nut use), higher monthly income, and specific occupations (such as service or manual work). Conclusions: Employment is independently associated with a higher risk of BAT use among low-income Taiwanese students. Work intensity and specific occupational fields may offer insights into formulating relevant preventive measures for these students.

Abstract
Human behavior can be controlled by physical or psychological dependencies associated with addiction. One of the most insidious addictions in our society is the use of tobacco products which contain nicotine. This addiction can be associated with specific receptors in the brain that respond to the natural neurotransmitter acetylcholine. These nicotinic acetylcholine receptors (nAChR) are ligand-gated ion channels formed by the assembly of one or multiple types of nAChR receptor subunits. In this paper, we review the structure and diversity of nAChR subunits and our understanding for how different nAChR subtypes play specific roles in the phenomenon of nicotine addiction. We focus on receptors containing β2 and/or α6 subunits and the special significance of α5-containing receptors. These subtypes all have roles in regulating dopamine-mediated neurotransmission in the mesolimbic reward pathways of the brain. We also discuss the unique roles of homomeric α7 nAChR in behavioral responses to nicotine and how our knowledge of nAChR functional diversity may help guide pharmacotherapeutic approaches for treating nicotine addiction. While nicotine addiction is a truly global problem, the use of areca nut (betel) products is also a serious addiction associated with public health issues across most of South Asia, impacting as many as 600 million people. We discuss how cholinergic receptors of the brain are also involved with areca addiction and the unique challenges for dealing with addiction to this substance.

Abstract
Background: Few traditions in South Asia have the antiquity and universal acceptance of betel quid and areca nut chewing. Its popularity dates back to ancient times in the South-Asian community with a foundation based on four factors, i.e. social acceptability, religious beliefs, perceived health benefits and addiction. We aim to provide an overview of its use in the South Asian region. Methods: We performed an electronic search on Medline, Embase and Google Scholar to identify the origins of the various betel quid and areca nut practices pertaining to the South Asian region along with their social and cultural influences. We also studied the prevalence across the region and the health effects, especially carcinogenic, along with the impact of diverse immigration today. Results: Other than the debate of where it originates, there is a diverse plethora of terms and methods of use of areca nut and betel quid in the region. Although established as a known carcinogen, the incidence is high, especially in the Indian subcontinent, with very few studies focusing on its use alone (without tobacco). The effect of globalization and increased movement of Asians across borders is resulting in changes in the patterns of diseases as well due to wider dissemination of areca nut and betel quid use. Conclusions: There is a huge loss of lives due to the addiction that areca nut causes. Governments need to tightly regulate the laws and set up tailored programs to tackle this specific issue in this region.

Abstract
Background: Areca nut (AN) is a carcinogenic substance consumed by roughly 600 million individuals worldwide with increasing popularity in Guam. In response, a cessation program was developed and implemented in Guam and Saipan. However, to improve its delivery, it is necessary to understand the reasons influencing recruitment and participation, such as why a chewer may not want to quit or join a cessation program. Objective: To explore barriers inhibiting chewers from quitting AN chewing and from participating in a cessation program. Methods: Nine individual and group discussions were facilitated with a convenience sample of 17 chewers and nonchewers in Guam in 2017. The mean age of the participants was 36.4 years. Recurring themes relating to reasons for not quitting and not joining a cessation program were extracted. Results: Results produced three general categories-Sociocultural, Behavioral, and Accessible. Each category encompasses different attributes concerning reasons not to quit chewing (e.g. addiction, enabling community, or belief that AN is harmless), and reasons influencing lack of participation in a cessation program (e.g. time, transportation, or relatability). Conclusions: Current findings suggest chewers are unaware of the harmful effects of AN. Also, they may not comprehend the purpose of a cessation program. In addition, the likelihood of chewers participating in a cessation program is influenced by their level of comfort with the program and personnel, and whether a program addresses their time and transportation limitations.

Abstract
Background: Areca nut (AN) and betel quid (BQ) are classified as Group 1 carcinogens. There are approximately 600 million AN/BQ users globally; the majority of users live in the Asia-Pacific region which, correspondingly, has the highest rates of oral cancer. Despite significant disease burden associated with AN/BQ use, there have been no systematic reviews of interventions to reduce product use. Objectives: To analyze interventions that prevent use of AN/BQ, present a basis for a future systematic review on the topic, and provide decision makers with examples of strategies that have demonstrated reduced AN/BQ use. Methods: To identify publications, we searched the literature using terms for AN/BQ and related synonyms in three databases: PubMed, Embase, and Scopus. Interventions that prevent AN/BQ use, that are published in English and that provide original data analysis, were included in this review. Interventions focused primarily on disease outcomes e.g. oral cancers (secondary prevention) were excluded. Results: Our search revealed 21 interventions targeting AN/BQ use between 1990 and 2018. Strategies include product bans, media campaigns, education, cessation, and taxation at individual and population levels, with varying evidence of impact. While these studies yielded some novel and promising findings, particularly regarding the impact of product bans, mass media campaigns, and cessation interventions, research on interventions specific to AN/BQ use remains limited. Conclusions: We have assessed published interventions that reduce AN/BQ use and identified future research priorities. These findings can be used to develop evidence-based interventions and help guide policymakers in implementing evidence-based policy to regulate these products.

Abstract
Background: Indonesia has the third largest population of smokers in the world, however, little is known about the use of chewing tobacco/betel quid in Indonesia. This paper describes the characteristics of chewing tobacco/betel quid users in Indonesia, to understand the user population and inform future research. Methods: The 2011 Indonesia GATS included 8,176 adults ages 15 and older. These data are weighted to be nationally representative. Weighted descriptive statistics and multivariate logistic regression were run using SAS 9.4. Results: Estimated national prevalence for exclusive chewing tobacco/betel quid use was 0.9%, for exclusive smoked tobacco use was 33.9% and for dual use was 0.8%. Multivariate logistic regression analyses showed that exclusive chewing tobacco/betel quid users were significantly more likely to be female, and to be older adults (45-64); while smokers are more likely to be male and younger (25-44). Conclusions/Importance: These results provide information on the different characteristics of users by product type, and show that users' demographics vary by their product of choice. This study helps to inform researchers and practitioners of the burden of chewing tobacco/betel quid use in Indonesia. These data, especially specific data on chewing tobacco/betel quid use patterns, are limited in this context, and this knowledge can help to identify populations who need quit tobacco interventions.

Abstract
Background: Betel quid chewing is a deep-rooted practice in India and neighboring countries, which has migrated to other parts of the world. Betel leaf acts as a carrier for areca nut and most often, smokeless tobacco, both of which are carcinogenic, making betel quid a harmful product. Objectives: The first objective was to compare the prevalence of "use of betel quid with tobacco" from GATS-1 to GATS-2. The second was to study the association of "use of betel quid with and without tobacco" with different socio-economic groups (wealth quintiles) according to select background characteristics. Methods: This study used data from the Global Adult Tobacco Surveys (GATS), 2009-10 and 2016-17. Logistic regression with adjustment of co-variates (age, gender, residence and education) was used to study association of use of betel quid with different socio-economic groups. Results: Highest reduction (40 percent) was seen in "use of betel quid with tobacco" among male youth (15-24 years) over the two rounds of GATS. No change was seen in this form of use among females. The odds of "use of betel quid with tobacco" had a positive gradient with decreasing wealth quintiles. "Use of betel quid without tobacco" showed highest odds among participants with moderate levels of education. Conclusion: Health promotion interventions around harmful effects of "betel quid with and without tobacco" are needed for all genders from poorer populations with low education. Stress needs to be laid on universal population-level public health awareness campaigns about the carcinogenic properties of areca nut in betel quid.

Abstract
Objective and method: Betel (areca) nut has recently received interest from researchers and policy makers for its role as a psychoactive substance. It was historically limited to Asia-pacific region, but with the advent of globalization, it has become an equally challenging public health problem across the globe. Previously published literature can give us valuable insights in terms of historical interest and understanding related to betel nut. With the expansion of biomedical research a huge number of articles have been published on the same. In terms of understanding the impact of an article, citations are considered a proxy estimate measure. Thus we decided to analyze the top 100 cited articles (till November 2018) related to betel nut. The search in Google scholar database was done with the help of freely available software, Publish or Perish. Results: Overall we found that most articles were published from the fields of dentistry and oncology, with relatively minimal contribution from the field of Addiction Psychiatry. Hence, most articles have addressed the issue of epidemiology and mechanism with lesser share of treatment related publications. Various important information related to these articles have been discussed including the institutions, countries, journals and impactful authors in the field. Subsequently, original research articles are further classified into descriptive/epidemiology, mechanism, management, scale/measurement, imaging and medical psychiatry. Importance: This citation analysis provides valuable information with regards to the emphasis of researchers in the field, and areas where more emphasis is required from contemporary world.

Abstract
Background: Betel nut (areca) is the world's fourth most commonly used addictive substance. Arecoline, a muscarinic agonist in areca, is also a partial agonist for the addiction-related high-affinity brain nicotine receptors. In many countries, smokeless tobacco is commonly mixed with areca. Objective: We sought to evaluate the knowledge of self-harm, and addiction associated betel quid use in an unban population. Methods: We conducted a survey study of 200 betel quid users in Yangon, Myanmar, and a survey of betel quid vendors to determine the relative amounts of areca and tobacco in the available quids. Results: The data determined that a large majority of the survey subjects (84%) used tobacco with their areca. Users had a general awareness that betel chewing was "a bad habit" (85%) and 80% were aware of the cancer risks. Understanding areca addiction remains a challenge since, aside from the strong muscarinic activity of arecoline stimulating salivation, overt neurologic effects are difficult for even the users to identify. Fifty eight percent of the respondents indicated that chewing betel quid had effects like drinking coffee, and 55.5% indicated that it had effects like drinking alcohol. Data obtained from the quid vendors indicated that 75% added tobacco in equal amounts to areca. Conclusion: The concomitant use of nicotine and areca indicates that betel quid addiction includes a significant component of nicotine dependence. However, the additional activities of areca, including the muscarinic effects of arecoline, indicate that potential cessation therapies should optimally address other factors as well.

Abstract
Areca Nut (AN), the seed of tropical palm tree Areca catechu, is a widely chewed natural product with estimated 600 million users across the world. Various AN products, thriving in the market, portray 'Areca nut' or 'Supari' as mouth freshener and safe alternative to smokeless tobacco. Unfortunately, AN is identified as a Group 1 human carcinogen by International Agency for Research on Cancer (IARC). Wide variation in the level of alkaloids, broadly ranging from 2 to 10 mg/gm dry weight, is observed in diverse variety of AN sold worldwide. For the first time, various factors influencing the formation of carcinogenic alkaloids in AN at various stages, including during the growth, processing, and storage of the nut, are discussed. Current review illustrates the mechanism of cancer induction by areca alkaloids in humans and also compiles dose-dependent pharmacology and toxicology data of arecoline, the most potent carcinogenic alkaloid in AN. Careful monitoring of the arecoline content in AN can potentially be used as a tool in product surveillance studies to identify the variations in characteristics of various AN sample sold worldwide. The article will help to generate public awareness and sensitize the government bodies to initiate campaigns against AN use and addiction.

Abstract
BACKGROUND Metformin, a widely used anti-diabetic drug has gained enormous attention as an anticancer agent. This study seeks to investigate the efficacy of metformin in ameliorating aqueous extract of betel-nut (AEBN) and arecoline induced carcinogenesis in a murine model. METHODS Swiss albino mice were exposed to AEBN (2 mg ml-1) and arecoline (10 μg ml-1) in drinking water for 16 weeks followed by co-administration of metformin (75 mg kg-1 or 150 mg kg-1) for 4 or 8 weeks. Histological changes and oxidative stress were assessed by haematoxylin and eosin staining, TBARS assay and protein carbonylation assay respectively. Lipid profile was determined using an automated analyzer. Expression of total and phosphorylated AMPK, ACC and p53 were determined by immunoblotting. RESULTS AEBN and arecoline induced dyslipidemia by downregulating AMPK (Thr-172) and activating ACC (Ser-79); they also downregulated tumor suppressor p53 (Ser-15). Metformin treatment induced AMPK-dependent alleviation of dyslipidemia in a dose and time dependent manner, upregulated p53 (Ser-15), restored tissue architecture and reduced oxidative stress in tissues of AEBN and arecoline treated mice. CONCLUSION This study establishes that betel nut induces dyslipidemia through its alkaloid, arecoline by inhibition of AMPK (Thr-172) and activation of ACC (Ser-79) and highlights the therapeutic potential of metformin for treatment of betel-nut induced carcinogenesis, indicating the repurposing of the old drug in a new avenue.

Abstract
BACKGROUND Smokeless tobacco (SLT) usage contributes about 40% of the total tobacco used in India. Among the 28 known carcinogens in SLT, tobacco-specific nitrosamines are considered to be the most potent. This has challenged the metabolic condition leading to a rise in the inflammatory status, hepatic injury, and apoptosis of the liver and thyroid tissues. Therefore, the present study was undertaken to evaluate the adverse effects of SLT on the liver and thyroid and establish a correlation between them in Jharkhand population. MATERIALS AND METHODS A total of 100 individuals (50 SLT users and 50 healthy individuals) were selected for the study. A complete history was obtained, and clinical examination was done to evaluate any oral mucosal changes. Venous blood samples were taken to analyze the liver function test and thyroid profile. RESULTS Significant changes were observed in the liver enzyme levels and thyroid profile in SLT users when compared to healthy controls. All the parameters of liver function test had a positive correlation with the form of SLT, whereas thyroid profile had a negative correlation. CONCLUSION This study might be helpful in creating awareness on the hazards of using SLT among the Indian population as a despicable substitute to smoking tobacco. It also acts as a diagnostic tool and warning alarm in chronic tobacco users.

Does adding a psychosocial cessation intervention to an existing life-skills and tobacco-prevention program influence the use of tobacco and supari among secondary school students?: Findings from a quasi-experimental trial in Mumbai, India. Tob Prev Cessat 2019; 5:45. [PMID: 32411907 PMCID: PMC7205047 DOI: 10.18332/tpc/113355] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Revised: 10/09/2019] [Accepted: 10/24/2019] [Indexed: 11/07/2022]
Abstract
INTRODUCTION This study aimed to test whether school-going adolescents who self-report tobacco and/or supari use are more likely to quit if a school-based psychosocial cessation intervention is added to an existing life-skills and tobacco-prevention program. METHODS A quasi-experimental trial with pre-test and post-test 20 weeks after the intervention was conducted with students from low-income families in 12 schools in Mumbai; six schools were randomly assigned to the intervention and the remaining to the comparison condition. Participants were students from grades 7, 8 and 9 who self-reported tobacco and/or supari use. Intervention schools received six sessions of LifeFirst, a psychosocial group-based tobacco cessation intervention program, in addition to SuperArmy, a school-wide life-skills and tobacco-prevention program. Trained counselors facilitated the cessation intervention, which spanned five months. All students in comparison schools received only SuperArmy. The outcome measures were self-reported use of tobacco-only, supari-only, and tobacco plus supari in the past 30 days. RESULTS The number of all users decreased by 19.1% in the intervention and 18.7% in the comparison schools at post-test. Although this reduction was significant (p<0.001) within each group, the difference between intervention and comparison schools was not significant. Further segregation by type of product used showed that for tobacco-only users there was a non-significant increase of 1.7% in intervention schools, and a significant 26.2% increase (p<0.001) in the comparison group. Tobacco plus supari use declined in both groups; however, supari-only use fell by 14.8% in the intervention and 32.7% in the comparison schools (p<0.01). CONCLUSIONS The combination of a cessation intervention along with the life-skills and tobacco-prevention program appear to have halted tobacco-only use in the intervention group. Future research needs to determine whether students are substituting supari for tobacco and to understand the psychological mechanisms underlying the cessation intervention and the interaction between cessation and prevention-only interventions.

Abstract
Problem Areca nut (AN) chewing is common among Southeast Asian population. Use of AN products (with or without tobacco) have a multifaceted effect on physical health, especially on cardiovascular, nervous, gastrointestinal, metabolic, respiratory, and reproductive systems. AN is a known group 1 carcinogen and carries addictive potential. Varying degrees of AN-related substance use disorder (SUD) have been reported among AN chewers. There is a lacuna in awareness of the health risk of AN use, prevention, and cessation programs among AN users, particularly in those who have developed SUD. Existing Lacunae The dynamic interaction of factors that promote AN use and later the risk of developing SUD at individual and community level has not been studied in depth. Understanding of the bio-psycho-socio-economic-cultural factors is necessary to identify the factors that prelude, promote, and reinforce AN usage. For managing AN-related conditions, including the several systemic disorders, there is a knowledge lacunae, among health care providers with respect to the pathophysiology of AN-related health issues, SUD, and nonavailability of structured, evidence-based cessation protocols. Solutions/Recommendations This manuscript presents a model-map to study the dynamics of AN use and the impact of AN on health and health care system at individual as well as community level. The model proposed can help the health policymakers to create evidence-based awareness and cessation protocols for AN.

Abstract
Betel quid is one of the most widely used psychoactive substances, and is consumed by approximately 10% of the world’s population. In addition to its carcinogenicity, betel quid has also been reported to affect many organs, including the brain, heart, lungs, gastrointestinal tract, and reproductive organs. As betel quid contains several neurotoxic ingredients, we hypothesize that it also possesses ototoxicity and may lead to sensorineural hearing impairment (SNHI). In this study, we investigated the contribution of betel quid consumption to SNHI in a large clinical cohort, and validated the pathogenetic mechanisms in ex vivo tissue explants. We enrolled a total of 2364 volunteers, and determined their audiologic results based on Z-scores converted from their original frequency-specific hearing thresholds. Using generalized linear regression, we identified a positive correlation between betel quid consumption and the Z-scores across different frequencies. Subsequently, we explored the toxicity of arecoline, the main neuroactive component of betel quid, on tissue explants from murine cochleae. Arecoline reduced cell activity in the explant cultures and induced apoptosis in the hair cells, probably through the effects of oxidative stress. These findings have expanded the potential hazards of betel quid to common neurological disorders, and provide insights into preventive strategies against SNHI caused by neurotoxic substances.

Abstract
OBJECTIVES Tobacco and areca nut are two of the most widely used psychoactive plant substances worldwide, yet the biocultural factors that account for variation in use patterns are not well understood. Here we attempt to understand the high prevalence of, and variation in, tobacco and areca nut use among reproductive-aged women. METHODS Research was carried out in Mysore, Karnataka, India. First, we conducted a qualitative investigation where participants engaged in semistructured interviews and focus group discussions to uncover cultural norms of women's tobacco use. Findings informed the second stage of research which quantitatively tested three models of tobacco and areca nut use (N = 74). RESULTS The qualitative study found that women were more likely to chew "natural" forms of tobacco and areca nut products (kaddipudi and paan). Quantitative tests of our hypotheses revealed that kaddipudi and combined tobacco use were best explained by the self-medication model, with somatic and environmental stress as strong indicators of use. The presence of cotinine, our biological indicator of tobacco use, was best modeled by gender inequality. We also found that men and women reported approximately equal tobacco use, even though their preferred types of tobacco and areca nut products differed. CONCLUSIONS Findings did not support the protection hypothesis as it relates to plant toxins. Instead, this study suggests that women might exploit neurotoxins such as nicotine and arecoline to offset the cognitive and energetic costs associated with iron deficiency in stressful environments.

Abstract
Arecoline is a naturally occurring psychoactive alkaloid from areca (betel) nuts of the areca palm ( Areca catechu) endemic to South and Southeast Asia. A partial agonist of nicotinic and muscarinic acetylcholine receptors, arecoline evokes multiple effects on the central nervous system (CNS), including stimulation, alertness, elation, and anxiolysis. Like nicotine, arecoline also evokes addiction and withdrawal symptoms (upon discontinuation). The abuse of areca nuts is widespread, with over 600 million users globally. The importance of arecoline is further supported by its being the world's fourth most commonly used human psychoactive substance (after alcohol, nicotine, and caffeine). Here, we discuss neuropharmacology, pharmacokinetics, and metabolism of arecoline, as well as social and historical aspects of its use and abuse. Paralleling clinical findings, we also evaluate its effects in animal models and outline future clinical and preclinical CNS research in this field.

Arecoline Promotes Migration of A549 Lung Cancer Cells through Activating the EGFR/Src/FAK Pathway. Toxins (Basel) 2019; 11:toxins11040185. [PMID: 30925742 PMCID: PMC6521018 DOI: 10.3390/toxins11040185] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2019] [Revised: 03/25/2019] [Accepted: 03/26/2019] [Indexed: 12/13/2022] Open
Abstract
Arecoline is the primary alkaloid in betel nuts, which are known as a risk factor for oral submucosal fibrosis and oral cancer. Lung cancer is a severe type of carcinoma with high cell motility that is difficult to treat. However, the detailed mechanisms of the correlation between Arecoline and lung cancer are not fully understood. Here, we investigated the effect of Arecoline on migration in lung cancer cell lines and its potential mechanism through the muscarinic acetylcholine receptor 3 (mAChR3)-triggered EGFR/Src/FAK pathway. Our results indicate that different concentrations of Arecoline treatment (10 µM, 20 µM, and 40 µM) significantly increased the cell migration ability in A549 and CL1-0 cells and promoted the formation of the filamentous actin (F-actin) cytoskeleton, which is a crucial element for cell migration. However, migration of H460, CL1-5, and H520 cell lines, which have a higher migration ability, was not affected by Arecoline treatment. The EGFR/c-Src/Fak pathway, which is responsible for cell migration, was activated by Arecoline treatment, and a decreased expression level of E-cadherin, which is an epithelial marker, was observed in Arecoline-treated cell lines. Blockade of the EGFR/c-Src/Fak pathway with the inhibitors of EGFR (Gefitinib) or c-Src (Dasatinib) significantly prevented Arecoline-promoted migration in A549 cells. Gefitinib or Dasatinib treatment significantly disrupted the Arecoline-induced localization of phospho-Y576-Fak during focal adhesion in A549 cells. Interestingly, Arecoline-promoted migration in A549 cells was blocked by a specific mAChR3 inhibitor (4-DAMP) or a neutralizing antibody of matrix metalloproteinase (MMP7 or Matrilysin). Taken together, our findings suggest that mAChR3 might play an essential role in Arecoline-promoted EGFR/c-Src/Fak activation and migration in an A549 lung cancer cell line.

Point-of-care, smartphone-based, dual-modality, dual-view, oral cancer screening device with neural network classification for low-resource communities. PLoS One 2018; 13:e0207493. [PMID: 30517120 PMCID: PMC6281283 DOI: 10.1371/journal.pone.0207493] [Citation(s) in RCA: 70] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Accepted: 10/30/2018] [Indexed: 01/17/2023] Open
Abstract
Oral cancer is a growing health issue in a number of low- and middle-income countries (LMIC), particularly in South and Southeast Asia. The described dual-modality, dual-view, point-of-care oral cancer screening device, developed for high-risk populations in remote regions with limited infrastructure, implements autofluorescence imaging (AFI) and white light imaging (WLI) on a smartphone platform, enabling early detection of pre-cancerous and cancerous lesions in the oral cavity with the potential to reduce morbidity, mortality, and overall healthcare costs. Using a custom Android application, this device synchronizes external light-emitting diode (LED) illumination and image capture for AFI and WLI. Data is uploaded to a cloud server for diagnosis by a remote specialist through a web app, with the ability to transmit triage instructions back to the device and patient. Finally, with the on-site specialist's diagnosis as the gold-standard, the remote specialist and a convolutional neural network (CNN) were able to classify 170 image pairs into 'suspicious' and 'not suspicious' with sensitivities, specificities, positive predictive values, and negative predictive values ranging from 81.25% to 94.94%.

Abstract
The toxicological assessment of plant products and pharmaceutical chemicals is a necessary requirement to ensure that all compounds are safe to be exposed to humans. Many countries are trying to reduce the use of animals; thus, alternative techniques, such as ex vivo tests, in vitro assays, and ex uteri embryos, are used. Toxicological assays using zebrafish embryos are an advantageous technique because they are transparent, have rapid embryonic development, and do not require invasive techniques. This paper comprehensively reviews how toxicity testing with plant products is conducted in zebrafish embryos. The search terms zebra fish, Danio rerio, zebrafish, zebra danio, Brachydanio rerio, zebrafish, and embryos were used to search for English-language articles in PUBMED, SCOPUS, and WEB OF SCIENCE. Twelve articles on plant product toxicity studies using zebrafish were selected for reading and analysis. After analyzing the articles and comparing with results in mammals, it was possible to prove the similarity among the results and thus corroborate the further development of zebrafish as a valid tool in toxicity tests.

Abstract
In the present study geraniol at the final concentration of 10, 20, 30, and 40 µM was mixed in the diet along with 80 µM of arecoline and the third instar larvae of transgenic Drosophila melanogaster (hsp70-lacZ) Bg9 were allowed to feed on it for 24 hrs. After the exposure of 24 hrs the larvae were subjected to ONPG, X-gal, trypan blue exclusion test, oxidative stress markers and apoptotic and comet assays. The exposure of larvae to geraniol showed a dose dependent decrease in the activity of β-galactosidase, tissue damage and oxidative stress markers. A dose dependent decrease in apoptosis and DNA damage was also observed. Molecular docking studies also support the protective role of geraniol against the arecoline induced toxicity. The results suggest that geraniol is potent in reducing the toxicity induced by arecoline in the third instar larvae of transgenic Drosophila melanogaster (hsp70-lacZ) Bg9.

A qualitative study of attitudes to and perceptions of betel quid consumption and its oral health implications in Taiwan. Community Dent Oral Epidemiol 2018; 47:58-64. [PMID: 30238494 DOI: 10.1111/cdoe.12422] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2017] [Revised: 07/09/2018] [Accepted: 08/15/2018] [Indexed: 10/28/2022]
Abstract
OBJECTIVES Betel quid (BQ) chewing is extremely prominent in South and Southeast Asia because it considered by users to be of social, cultural and religious importance. BQ chewing has been recognized as a risk factor for oral premalignant lesions and oral cancer. Because BQ chewing has become a severe health risk in Taiwan, the development of prevention and cessation programmes is essential. The purpose of this study was to explore the attitudes and perceptions associated with BQ consumption and its oral health implications in an attempt to inform the development of health promotion initiatives and BQ cessation efforts in Taiwan, where the dental profession could have a pivotal role in preventing and controlling BQ use among persons at risk. METHODS This qualitative study used data gathered from focus groups and individual interviews. A convenience sample of 41 adults from Jhushan and Lugu Townships (Nantou County) and Taichung City, Taiwan, participated in this study (27 men, 14 women; 31 Han, 10 aboriginals from the Paiwan tribe; mean age 40.3, SD 9.2 years). RESULTS Among the seven themes that emerged from the original study, five (Initiation, Health Risk Perception, Health Consequences, Withdrawal Symptoms and Help from Healthcare Providers) had oral/dental implications. CONCLUSIONS Our study highlights research areas relevant to further investigation, such as incorporating brief BQ prevention and cessation counselling when early oral and dental signs associated with BQ consumption are detected. Undertaking behavioural interventions in dental settings might help to reduce the prevalence of BQ chewing in Taiwan.
