Birth Defects Res 2023; 115:967-979. [PMID: 37078627 DOI: 10.1002/bdr2.2180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 03/09/2023] [Accepted: 04/08/2023] [Indexed: 04/21/2023]
Abstract
Areca nut (AN) and smokeless tobacco (SLT) are indiscriminately consumed among the populations of Southeast and South Asian countries, even by women during the gestational period. This study aimed to investigate the genotoxic and cytotoxic potentials of AN and Sadagura (SG), a unique homemade SLT preparation, alone and in combination in early chick embryos. Fertile white leghorn chicken eggs were randomly divided into five treatment groups: vehicle control, positive control (Mitomycin C, 20 μg/egg), AN, SG, and AN+SG. AN, SG, and AN+SG were given at dosages of 0.125, 0.25, and 0.5 mg/egg. The hen's egg test for micronucleus induction (HET-MN) was performed in chick embryos to evaluate the genotoxic potential of the test agents. Furthermore, the cytotoxic potential was assessed by studying erythroblast cell populations and the polychromatic erythrocytes (PCEs) to normochromatic erythrocytes (NCEs) ratio. Our results indicated a significant increase (p < .001) in MN frequency and other nuclear abnormalities, suggesting the potential of AN and SG to cause genotoxicity. Also, AN and SG exposure alone and in combination considerably altered the erythroblast cell population (%) and the PCE to NCE ratio in all the treatment periods. Our findings established the genotoxic and cytotoxic potential of both AN and SG alone and in combination during early embryonic development in the chick embryo.

Potential benefits versus hazards of herbal therapy during pregnancy; a systematic review of available literature. Phytother Res 2022; 36:824-841. [PMID: 35023227 DOI: 10.1002/ptr.7363] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 11/03/2021] [Accepted: 12/10/2021] [Indexed: 11/07/2022]
Abstract
The use of herbal medicine has considerably grown worldwide in the past two decades. Studies have shown that the prevalence of herbal diet therapy in pregnancy ranged from 1% to 60% in different societies. Many clinical reports have shown that some herbal medicines may have toxic effects on pregnant women and their fetuses because active ingredients of some medicinal plants can readily pass through the biological barriers (e.g., placental barrier). In the present study, we aimed to systematically review the literature to discover potential benefits versus the hazards of herbal therapy during pregnancy. For this purpose, a comprehensive literature review was performed, and after the literature search and selection of the appropriate documents, the desired data were extracted and reported. From 35 articles with a total of 39,950 study population, the results showed that some medicinal plants could cause severe toxicity on mothers and fetuses, in addition to abortion during pregnancy. It was also shown that some plants may lead to developmental abnormalities or fetal death. Findings of this survey showed that some herbal medicines have toxic, teratogenic, and abortive potential, particularly in the first trimester of pregnancy because active ingredients of some medicinal plants are able to pass through the placental barrier and reach the fetus.

Abstract
Areca nut (AN) was identified as carcinogenic to humans. Around 600 million people globally use AN in some form, yet no effective therapeutic drug is available to overcome AN addiction. This preclinical study examines the effects of antidepressants on AN use with animal models. We produced AN powder and dissolved it into drinking water, training 55 C57BL/6 mice in free self-selection to drink AN water or normal water. Then, the mice were randomly divided into four groups. Selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs), and tricyclic antidepressants (TCAs) were given as three treatment groups and one placebo group for four weeks. In the follow-up period, the preference and amount of free selection of AN and normal water, and oral pathological change were evaluated. There was a significant decrease in preference for AN drinking during the first four weeks, and the 36th week after drug withdrawal in the MAOI and SSRI groups (all p < 0.05). The drug-reducing effect of AN water in the 1–4-week period was significant in the MAOI group (p < 0.0001) and was also significant in the 3–4-week period in the SSRI group (p = 0.03). The TCA group did not show a decrease effect. At the endpoint (60 weeks), oral mucosal fibrosis (OSF) levels and risk in the SSRI (p = 0.0081) and MAOI (p = 0.01) groups were significantly lower than those in the control group. Antidepressant drugs MAOIs and SSRIs could reduce the amount of AN use and decrease the early stage of oral fibrosis in mice, but SSRIs may need to be boosted again.

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.

Betel Quid Health Risks of Insulin Resistance Diseases in Poor Young South Asian Native and Immigrant Populations. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17186690. [PMID: 32937888 PMCID: PMC7558723 DOI: 10.3390/ijerph17186690] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Revised: 09/02/2020] [Accepted: 09/03/2020] [Indexed: 01/30/2023]
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
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.

Abstract
Gestational risk factors such as birth weight, gestational age and parity have been repeatedly found to be related to pediatric cancers, but few reports have emerged from Asian countries. Here we report on demographic and gestational factors in a Taiwanese cohort. Our study included all children born in Taiwan 2004-2014 for whom there was a birth record (n = 2,079,037), of which 1900 children had been diagnosed with cancer prior to age 12. We conducted multivariable hazard regression to examine associations between demographic and gestational factors with cancer. Greater parity (family with 2+ older children) was related to acute myeloid leukemia [Hazard ratio (HR) = 2.15, 95% confidence interval (CI): 1.31, 3.55), central nervous system tumors (HR = 1.67, CI: 1.13, 2.48) and neuroblastoma (HR = 1.67, CI: 1.07, 2.63). Hepatoblastoma cases had a higher risk of low birth weight (<2,500 g; HR = 3.01, CI: 1.85, 4.91), very preterm birth (<33 weeks gestation; HR = 13.71, CI: 7.45, 25.23), plural pregnancies (HR = 2.37, CI: 1.10, 5.14) and both small (HR = 2.13, CI: 1.23, 3.67) and large (HR = 1.83, CI: 1.01, 3.32) for gestational age. Germ cell tumors were more common among children born in rural areas (HR = 1.63, CI: 1.02, 2.60). Despite that Taiwan has lower rates of both high and low birthweight compared to other developed nations, we observed several similar associations to those reported in Western Countries. Further research should examine unique exposures in Taiwan that may be contributing to higher incidence of certain cancer types.

Abstract
All individuals are exposed to certain chemical, physical, biological, environmental as well as occupational factors. The data pertaining to role of these factors on female reproduction are scanty as compared to male. The available data suggest the adverse effects of certain toxicants, viz., metals such as lead, cadmium and mercury, pesticides such as bis(4-chlorophenyl)-1,1,1-trichloroethane and organic solvent such as benzene, toluene and ionizing radiation on the female reproductive system affecting directly the organ system or impacting in directly through hormonal impairments, molecular alterations, oxidative stress and DNA methylation impairing fertility as well as pregnancy and its outcomes. Thus, there is a need for awareness and prevention programme about the adverse effects of these factors and deterioration of female reproductive health, pregnancy outcome and offspring development as some of these chemicals might affect the developing foetus at very low doses by endocrine disruptive mechanism.

OBJECTIVE Oral cancers caused by chewing betel nuts have a poor prognosis. Using a lay health advisor (LHA) can increase access to health care among underprivileged populations. This study evaluated a health belief model (HBM) intervention using LHAs for oral cancer screening (OCS) and mouth self-examination (MSE) in remote aboriginal communities. METHODS The participants were randomly assigned to intervention (IG; n = 171) and control groups (CG; n = 176). In the IG, participants received a three-chapter one-on-one teaching course from LHAs, whereas those in the CG received only a leaflet. RESULTS The IG participants were 2.04 times more likely to conduct a monthly MSE than those in the CG (95% confidence interval: 1.31-3.17) and showed significantly higher self-efficacy levels toward OSC and MSE (β = 0.53 and 0.44, effect size = 0.33 and 0.25, respectively) and a lower barrier level for OSC (β = -1.81, effect size = -0.24). CONCLUSION The LHA intervention had a significantly positive effect on MSE, strengthening self-efficacy and reducing barriers to OCS among aboriginal populations. PRACTICE IMPLICATIONS The effectiveness of the clinical treatment of underprivileged group can be improved through early diagnosis, which can be achieved using LHAs to reduce barriers to OSC.

Abstract
BACKGROUND Betel nut is the fourth most commonly abused substance worldwide and has been associated with significant adverse health outcomes. Little is known about its effects on the fetus. OBJECTIVE To perform a systematic review of studies investigating prenatal betel nut use and adverse perinatal outcomes. SEARCH STRATEGY Pubmed, Embase, and Cochrane databases were searched from inception until July 2018 using the terms areca, betel nut, pregnancy, pregnancy complications, and infection. SELECTION CRITERIA Eligible studies included case-control, cohort, and randomized control studies involving pregnant women. DATA COLLECTION AND ANALYSIS Where appropriate, bivariate meta-analysis was performed, and odds ratios (ORs) and 95% confidence intervals (CIs) were calculated. MAIN RESULTS In total, 28 studies were screened and eight studies (including 15 270 women) were included in the review and meta-analysis. Preterm birth, low birthweight, and anemia were most commonly investigated. Meta-analysis revealed a significant association between betel nut use and low birthweight, with a pooled OR of 1.75 (95% CI, 1.35-2.27). CONCLUSIONS The review identified only eight eligible studies, all based in the Asia-Pacific region. There was a significant association between low birthweight and betel nut exposure in pregnancy. Further prospective studies are needed to confirm this association.

Abstract
Introduction Although other studies have found evidence for perinatal health disparities among Pacific Islanders in other regions, no studies have evaluated racial/ethnic disparities in adverse perinatal health outcomes in the small US island territory of the Commonwealth of the Northern Mariana Islands (CNMI). Methods We used retrospective cohort data on 8,427 singleton births from 2007 to 2014 at the Commonwealth Healthcare Corporation (CHCC), the only hospital in the CNMI. We used multivariate logistic regression to estimate risk for preterm birth (<37 weeks) and macrosomia (>4,000 g) among the racial/ethnic groups in the CNMI. Results Indigenous CNMI mothers (Chamorros and Carolinians, hereinafter Chamorro/Carolinian) and other Pacific Islander mothers were significantly more likely to have a preterm birth than Chinese mothers (adjusted odds ratio [AOR] = 2.7; 95% confidence interval [CI], 2.0–3.6 for Chamorro/Carolinians and AOR = 2.9; 95% CI, 2.1–4.1 for other Pacific Islanders). Additionally, Chamorro/Carolinian mothers and other Pacific Islander mothers were also significantly more likely to deliver babies with macrosomia (AOR = 2.4; 95% CI, 1.7–3.5 and 2.3; 95% CI 1.4–3.6 respectively) than Filipino mothers. Conclusion Although underlying causes for these disparities are still unknown, these findings add to the limited knowledge on maternal and neonatal health among Pacific Islanders and provide support for further research and intervention development to aid in reducing racial/ethnic disparities of perinatal health in the CNMI.

Abstract
Global reports estimate 600 million betel quid (BQ) chewers. BQ chewing has been demonstrated not only to be a risk factor for cancers of the oral cavity and pharynx and oral potentially malignant disorders (OPMD) but also to cause other cancers and adverse health effects. Herein, we summarized the international comparison data to aid in the understanding of the close relationship between the prevalence of BQ chewing, the occurrence of oral and pharyngeal cancers, and adverse health effects. Potential biomarkers of BQ carcinogens, such as areca nut, alkaloids, and 3-methylnitrosaminopropionitrile (MNPN), are closely associated with human health toxicology. Molecular mechanisms or pathways involving autophagy, hypoxia, COX-2, NF-κB activity, and stemness are known to be induced by BQ ingredients and are very closely related to the carcinogenesis of cancers of oral and pharynx. BQ abuse-related monoamine oxidase (MAO) gene was associated with the occurrence and progress of oral and pharyngeal cancers. In summary, our review article provides important insights into the potential roles of environmental BQ (specific alkaloid biomarkers and nitrosamine products MNPN) and genetic factors (MAO) and offers a basis for studies aiming to reduce or eliminate BQ-related OPMD and oral/pharyngeal cancer incidences in the future.

Abstract
AIM We present a systematic review of substance use disorder (SUD) to Areca catechu nut (AN) and AN containing betel quid (ANcBQ) with emphasis on dependence resulting from chewing of tobacco-free ANcBQ. We examined pharmacology of intoxication and addiction, and factors influencing quitting strategies. METHODS Epidemiological publications of SUD were included according to PRISMA criteria. Pharmacological publications were retrieved from the PUBMED database and websites of the WHO, United Nations, and Sigma-Aldrich. RESULTS Nine epidemiological studies show clear evidence of abuse and dependence in tobacco-free ANcBQ and/or ANcBQ+Tobacco chewers. Dependency is greater if ANcBQ contains tobacco. In both groups higher dependency scores were positively correlated with higher frequency of chewing. Dependency on AN+Lime is associated with altered brain morphology, resting state brain activity, neurochemistry and deterioration of working spatial memory. ANcBQ contains a complex mixture of neuroactive compounds that have the potential to act directly upon all major cerebral neurotransmitter systems. Of these compounds, only arecoline (muscarinic agonist) has been the focus of limited pharmacological investigation. In animal studies, arecoline increases dopamine transmission in the mesocorticolimbic circuit and this action may be one factor contributing to ANcBQ dependency in humans. Societal and familial acceptance of ANcBQ consumption is paramount for commencement and persistence of chewing. CONCLUSIONS ANcBQ SUD remains an orphan disease. The limited understanding of pharmacological basis of intoxication and SUD determines there are no pharmacological replacement therapies for ANcBQ SUD. The addictive properties of ANcBQ coupled with social acceptance of ANcBQ chewing limits the effectiveness of counseling-based quitting programs.

Abstract
The small Pacific Island nation of Palau has alarmingly high rates of betel nut with tobacco use and obesity among the entire population including pregnant women. This study aimed to determine the effects of betel nut with tobacco use and pre-pregnancy obesity on adverse birth outcomes. This study used retrospective cohort data on 1171 Palauan women who gave birth in Belau National Hospital in Meyuns, Republic of Palau between 2007 and 2013. The exposures of interest were pre-pregnancy obesity and reported betel nut with tobacco use during pregnancy. The primary outcomes measured were preterm birth and low birth weight among full-term infants. A significantly increased risk for low birth weight among full-term infants was demonstrated among those women who chewed betel nut with tobacco during pregnancy when other known risk factors were controlled for. Additionally, pre-pregnancy obesity was associated with a significantly increased risk for preterm birth when other known risk factors were controlled for. Both betel nut with tobacco use and pre-pregnancy obesity were associated with higher risks for adverse birth outcomes. These findings should be used to drive public health efforts in Palau, as well as in other Pacific Island nations where these studies are currently lacking.

Abstract
Background Chewing areca nut (AN), also known as betel nut, is common in Asia and the South Pacific and the habit has been linked to a number of serious health problems including oral cancer. Use of AN in pregnancy has been associated with a reduction in mean birthweight in some studies, but this association and the relationship between AN chewing and other adverse pregnancy outcomes remain poorly understood. Methods We assessed the impact of AN chewing on adverse outcomes including stillbirth, low birthweight (LBW, <2,500 g) and anaemia at delivery (haemoglobin <11.0 g/dL) in a longitudinal cohort of 2,700 pregnant women residing in rural lowland Papua New Guinea (PNG) from November 2009 until February 2013. Chewing habits and participant characteristics were evaluated at first antenatal visit and women were followed until delivery. Results 83.3 % [2249/2700] of pregnant women used AN, and most chewed on a daily basis (86.2 % [1939/2249]. Smoking and alcohol use was reported by 18.9 % (511/2700) and 5.0 % (135/2688) of women, respectively. AN use was not associated with pregnancy loss or congenital abnormalities amongst women with a known pregnancy outcome (n = 2215). Analysis of 1769 birthweights did not demonstrate an association between AN and LBW (chewers: 13.7 % [200/1459] vs. non-chewers: 14.5 % [45/310], P = 0.87) or reduced mean birthweight (2957 g vs. 2966 g; P = 0.76). Women using AN were more likely to be anaemic (haemoglobin <11 g/dL) at delivery (75.2 % [998/1314] vs. 63.9 % [182/285], adjusted odds ratio [95 % CI]: 1.67 [1.27, 2.20], P < 0.001). Chewers more commonly had male babies than non-chewers (46.1 % [670/1455] vs. 39.8 % [123/309], P = 0.045). Conclusions AN chewing may contribute to anaemia. Although not associated with other adverse pregnancy outcome in this cohort gestational AN use should be discouraged, given the potential adverse effects on haemoglobin and well-established long-term health risk including oral cancer. Future research evaluating the potential association of AN use and anaemia may be warranted. Trial registration ClinicalTrials.gov NCT01136850 (06 April 2010).

Abstract
Betel quid chewing is associated with various oral cancers and other health concerns, including reproductive health issues. Nevertheless, the practice is widespread in Myanmar, especially among men. This qualitative study elucidates the gendered aspects of betel quid chewing by examining how it links with masculine ideology among male betel quid chewers in Mandalay, Myanmar. Data were collected through in-depth interviews, focus-group discussions, key-informant interviews and participant observation. The thematic content analysis was guided by Connell's concept of hegemonic masculinity and Butler's notion of gender performativity. The findings indicated that young Mandalay men were drawn to betel quid chewing by the value they gave to satisfying their curiosity, power competition, risk-taking and a display of manliness. Thus, the practice of betel quid chewing, as defined by our participants, was perceived as manly, trendy, stylish and sexually attractive. For adult men, betel quid chewing was a social lubricant that assisted them in talking with clients and co-workers, thus enhancing their economic opportunities with other men. It also helped working-class men to work harder. Betel quid chewing harm-reduction programmes therefore need to be mindful of masculinity issues as well as the economic aspects of betel quid chewing.

Abstract
The areca nut-chewing habit is common in Southeast Asia, India, and Taiwan, and arecoline is the most abundant and potent component in the areca nut. The effects of arecoline on birth defects have been explored in many species, including chicken, mice, and zebrafish. The effects of arecoline on embryos after long-term exposure are well established; however, the effects of short-term embryo exposure to arecoline are not understood. Using zebrafish, we study the effects of short-term exposure of arecoline on embryos to model the human habit of areca nut-chewing during early pregnancy. Arecoline, at concentrations from 0.001% to 0.04%, was administered to zebrafish embryos from 4 to 24 hours post fertilization. The morphological changes, survival rates, body length, and skeletal muscle fiber structure were then investigated by immunohistochemistry, confocal microscopy, and conventional electron microscopy. With exposure of embryos to increasing arecoline concentrations, we observed a significant decline in the hatching and survival rates, general growth retardation, lower locomotor activity, and swimming ability impairment. Immunofluorescent staining demonstrated a loose arrangement of myosin heavy chains, and ultrastructural observations revealed altered myofibril arrangement and swelling of the mitochondria. In addition, the results of flow-cytometry and JC-1 staining to assay mitochondria activity, as well as reverse transcription-polymerase chain reaction analyses of functional gene expression, revealed mitochondrial dysfunctions after exposure to arecoline. We confirmed that short-term arecoline exposure resulted in retarded embryonic development and decreased locomotor activity due to defective somitic skeletal muscle development and mitochondrial dysfunction.

Abstract
This cross-sectional study aims to examine the prevalence and correlates of harmful alcohol use among aboriginal people in southern Taiwan and to examine the associations between harmful alcohol use and adverse drinking effects. Four hundred forty-nine aboriginal adults were recruited from two townships in southern Taiwan to complete the questionnaires. Among the aborigines, 59.7% scored an 8 or above on the Alcohol Use Disorders Identification Test, including 26.7% who were found to be hazardous drinkers (AUDIT level II), 18.5% who were harmful drinkers (level III), and 14.5% who were with likely dependence (level IV). Male aborigines who participated less in religious activities, had stressful life events, were cigarette smokers, or were betel quid chewers were more likely to have harmful alcohol use. Harmful alcohol use was also associated with an inability to work and with arguments with other people. Our study suggests that aboriginal people in southern Taiwan experience alcohol-related risks at rates as high as other worldwide populations for which AUDIT results are available. Individuals with AUDIT scores at levels II and III are generally candidates for brief interventions delivered in generalist health settings. Individuals with AUDIT scores at level IV should be referred for an addiction specialty evaluation and possible treatment as well as lower-risk individuals (those with AUDIT levels II-III) if they have concurrent physical or psychiatric disorders.

Abstract
Background Arecoline, a major alkaloid in Areca nut has the ability to induce oxidative stress. The effect of Areca nut, arecoline on reducing sperm quality and quantity were documented previously using several animal models. Junction disruption by down-regulation of the junction-adhesive protein via oxidative stress is an important route mediating abnormal spermatogenesis. Therefore, in this present study, we investigated the functional role of arecoline on junctional proteins. Results To analyze direct effects of arecoline on testis cells, confluent mouse testicular Sertoli cell line TM4 was exposed to arecoline. Arecoline decreased insoluble zonula occludens-1 (ZO-1) protein expression in TM4 cells, however, arecoline treatment increased TNF-alpha production in both TM4 and monocytic THP1 cells. In addition, ERK1/2 inhibitor PD98059 reversed arecoline effects on TNF-alpha and ZO-1. Conclusions Arecoline increases the production of TNF-alpha and induces protein redistribution of ZO-1. All these results explain the role of arecoline in male reproductive dysfunction, besides its cytotoxic induction.

Betel-quid dependence domains and syndrome associated with betel-quid ingredients among chewers: an Asian multi-country evidence. Addiction 2014; 109:1194-204.

Abstract
AIMS Betel-quid (BQ) contains biologically psychoactive ingredients; however, data are limited concerning the symptoms and syndrome of BQ dependence among chewers. The aims of this study were to evaluate the ingredients-associated BQ dependence syndrome and country-specific chewing features and behaviour for BQ dependence among chewers from six Asian communities. DESIGN An intercountry Asian Betel-quid Consortium study. SETTING Six Asian general communities in Taiwan, Mainland China, Indonesia, Malaysia, Sri Lanka and Nepal. PARTICIPANTS Six multi-stage random samples of BQ chewers in the Asian Betel-quid Consortium study (n = 2078). MEASUREMENTS All chewers were evaluated for BQ dependence using the DSM-IV and ICD-10 criteria. FINDINGS The 12-month BQ dependence rate was 12.5-92.6% and 47.9-99.3% (P = 0.023) among tobacco-free and tobacco-added BQ chewers across the six Asian communities, with a higher dependence rate in chewers who used tobacco-free BQ with lime added than without (23.3-95.6% versus 4.0%, P ≤ 0.001). Taiwanese and Hunanese BQ chewers both notably endorsed the dependency domain of 'time spent chewing'. 'Tolerance' and 'withdrawal' were the major dependence domains associated with the Nepalese and Indonesian chewers, with high BQ dependence rates. Malaysian and Sri Lankan chewers formed a BQ dependence cluster linked closely to 'craving'. In Sri Lanka, the quantity consumed explained 90.5% (P < 0.001) of the excess dependence risk for tobacco-added use, and could be a mediator between tobacco-derived psychoactive effect and BQ dependence development. CONCLUSIONS DSM-IV criteria for dependence apply to a significant proportion of betel quid users in Asian communities, more so if they use it with tobacco or lime.

Abstract
In this study, we provided an empirical examination of the interaction between people's health risk perception and betel chewing. We hypothesized that a better knowledge of possible health risks would reduce both the number of individuals who currently chew betel and the likelihood of those who do not yet chew betel to begin the habit. We constructed a simultaneous equation model with Bayesian two-stage approach to control the endogeneity between betel chewing and risk perception. Using a national survey of 26,684 observations in Taiwan, our study results indicated that better health knowledge reduced the possibility that people would become betel chewers. We also found that, in general, betel chewers have a poorer health risk perception than other population. Overall, the empirical evidence suggested that health authorities could reduce the odds of people becoming betel chewers by improving their knowledge of betel-chewing's harmful effects.

Abstract
Eight manuscripts have specifically examined the effects of areca (betel) nut use in pregnant women, seven of which have documented adverse effects on birth weight, newborn neurological status, gender ratio and pregnancy outcomes such as anaemia and miscarriage following areca nut use during pregnancy. A retrospective cohort analysis of migrant and refugee pregnant women attending antenatal clinics along the Thai–Myanmar border (July 1997 to November 2006) was conducted to examine the adverse effects of areca nut use routinely recorded on enrolment. Of 7685 women, 2284 (29.7%) never used areca or smoked (cheroots), 2484 (32.3%) only used areca, 438 (5.7%) only smoked cheroots and 2479 (32.3%) used both areca and cheroots. Pieces of ripe areca nut in a leaf with lime, without tobacco, were used particularly among older multigravid women. Adverse pregnancy effects were not observed in areca nut users compared with non-users. Smoking, but not areca nut use, had a dose-related effect on miscarriage. Areca nut use in conjunction with smoking reduced the adverse effects of smoking on birth weight, further supporting a lack of effect of areca nut. Areca (betel) nut-related adverse pregnancy outcomes were not observed in this population, whereas smoking was clearly harmful. Differences from previous reports may result from the amount or types of areca nut, or quid content, consumed between countries. Smoking, but not areca nut, reduction is likely to improve pregnancy outcomes on the Thai–Myanmar border.

Abstract
In the Western Pacific Region, rural women use loose tobacco in betel quid chewing and pipe smoking. We examined the relation between maternal use of tobacco and infant mortality (IM) in a national sample of 24 296 birth outcomes in adult women (n = 6013) in Cambodia. We found that (1) age-adjusted odds of IM were higher for maternal use of any tobacco (odds ratio [OR] = 1.69; 95% confidence interval [CI] = 1.27-2.26); (2) age-adjusted odds of IM were higher for cigarette use (OR = 2.54; 95% CI = 1.54- 4.1), use of pipes (OR = 3.09; [95% CI = 1.86-5.11]), and betel quid chewing (OR = 1.55; 95% CI = 1.10-2.17); and (3) these associations remained after multivariable adjustment for environmental tobacco smoke, malnutrition, ethnicity, religion, marital status, education, income, occupation, and urban/rural dwelling. In addition to finding the established association with cigarettes, we also found that maternal use of smokeless tobacco and pipes was associated with higher rates of infant death in Cambodia.

Abstract
Although current trends indicate that the rate of cigarette smoking tends to be low among women in the Western Pacific Region (<10%), recent epidemiologic data from South Asia (India, Bangladesh) and Southeast Asia (Cambodia, Vietnam, Indonesia, Malaysia) identify that a large proportion of women of reproductive age and older chew tobacco—often as part of a betel quid mixture that includes other potentially harmful ingredients (eg, areca nut). Our findings from currently pregnant women identified during a nationwide survey of adult tobacco use in Cambodia indicate that 13.0% (95% confidence interval [CI] = 8% to 17%) were current users of smoked or smokeless (in the form of a betel quid) tobacco. Most pregnant women who used tobacco indicated that their habit was either initiated (29.1%; 95% CI = 16.3-46.3) or increased (33.7%; 95% CI = 18.3-53.5) during pregnancy. Pregnancy-related symptoms such as morning sickness were reported as the reason for more than half (54.9%; 95% CI = 34.8-73.4) of the currently pregnant users to have started a tobacco habit during their lifetime. Among those pregnant women who did not use tobacco, we found strong associations (odds ratios from 2 to 14) with beliefs about the harmful effects of tobacco on adult health, faith-based beliefs in addictive substances, and beliefs that influential members of the community, health professionals, and children should not use tobacco. Our findings indicate that tobacco cessation and prevention programs in Cambodia should specifically target pregnant and reproductive-age women.

Abstract
The secondary sex ratio (SSR) has been suggested to decrease with adverse physical and psychological environments. Previous studies have focused on reduced SSR under adverse conditions, such as war, terrorism attack and earthquake, but few studies have investigated fluctuations in SSR in moderately adverse environments. This study analysed municipality-level vital statistics records in Japan collected between 1998 and 2002 to identify high-SSR clusters and low-SSR clusters with spatial-scan statistics. In 999 runs of simulation, high- and low-SSR clusters were detected but fewer than 950 times, indicating that SSR was not geographically clustered in Japan if type I error of 5% was adopted. Explorative analyses comparing demographic attributes between high-SSR clusters and low-SSR clusters that were detected more than 500 times in 999 runs of simulation, showed that rate of spontaneous abortion, rate of artificial abortion and divorce rate were higher in low-SSR clusters, while male life expectancy, female life expectancy and total fertility rate were higher in a high-SSR cluster.

Abstract
ABSTRACT
The habit of chewing areca is a habit of great antiquity. The word ‘areca’ is derived from the Malay word adakka (areca nut) or from adakeya, the Indian equivalent. Arecoline, the principal alkaloid in areca nut, acts as an agonist primarily at muscarinic acetylcholine receptors and stimulates the central and autonomic nervous system. This leads to subjective effects of increased well-being, alertness and stamina. It is known to improve concentration and relaxation, with other reported effects including lifting of mood, cariostatic property and also exerts a direct antimicrobial effect against bacteria. Arecaidine may have anxiolytic properties through inhibition of gamma-amino butyric acid (GABA) reuptake.
Despite these general effects, the adverse effects have outweighed them. Betal quid chewing is one of the major risk factors of hepatocarcinoma, oropharyngeal and esophagus cancers. Arecoline, the main areca alkaloid of the betel nut, is reported to have cytotoxic, genotoxic and mutagenic effects in various cells. It shows strong correlation to the incidence of oral submucosal fibrosis, leukoplakia and oral cancer, and has also been found to impose toxic manifestations in immune, hepatic and other defense systems of the recipient.

Abstract
BACKGROUND Despite gradual understanding of the multidimensional health consequences of betel-quid chewing, information on the effects of dependent use is scant. AIMS To investigate the 12-month prevalence patterns of betel-quid dependence in six Asian populations and the impact of this dependence on oral potentially malignant disorders (OPMD). METHOD A multistage random sample of 8922 participants was recruited from Taiwan, mainland China, Indonesia, Malaysia, Sri Lanka and Nepal. Participants were evaluated for betel-quid dependency using DSM-IV and ICD-10 criteria and assessed clinically for oral mucosal lesions. RESULTS The 12-month prevalence of dependence was 2.8-39.2% across the six Asian samples, and 20.9-99.6% of those who chewed betel-quid were betel-quid dependent. Men dominated the prevalence among the east Asian samples and women dominated the prevalence in south-east Asian samples. 'Time spent chewing' and 'craving' were the central dependence domains endorsed by the Chinese and southern/south-east Asian samples respectively, whereas the Nepalese samples endorsed 'tolerance' and 'withdrawal'. Dependency was linked to age, gender, schooling years, drinking, smoking, tobacco-added betel-quid use and environmental accessibility of betel-quid. Compared with non-users, those with betel-quid dependency had higher pre-neoplastic risks (adjusted odds ratios 8.0-51.3) than people with non-dependent betel-quid use (adjusted odds ratio 4.5-5.9) in the six Asian populations. CONCLUSIONS By elucidating differences in domain-level symptoms of betel-quid dependency and individual and environmental factors, this study draws attention to the population-level psychiatric problems of betel-quid chewing that undermine health consequences for OPMD in six Asian communities.

Abstract
Betel quid chewing is associated with cytotoxicity, genotoxicity and carcinogenicity in diseases such as oral cancer, liver cirrhosis, hepatocellular carcinoma and diabetes mellitus. Arecoline and arecaidine, which are the main alkaloids in the areca nut, are potential exposure biomarkers in habitual betel quid users. This study developed a method of detecting arecoline- and arecaidine-protein adducts by mass spectrometry (MS). First, bovine serum albumin was used to predict and confirm the binding sites of proteins modified by arecoline or arecaidine. Cells were then treated with arecoline to identify new protein adducts after cellular metabolic processing. Finally, human plasma was used to model long-term exposure to arecoline and arecaidine. Following isolation proteins were tryspin digested. The peptides afforded were separated and analyzed by nano-scale liquid chromatography with MS using an LTQ Orbitrap mass spectrometer. The experimental findings showed that cysteine is the predominant amino acid in protein adduct formation. The goal of this study was to establish a screening platform for identifying novel protein adducts that form covalent bonds with arecoline or arecaidine. Use of this strategy to survey new protein-toxic adducts may help to identify novel biomarkers of betel nut exposure.

Abstract
An improved high-performance liquid chromatography (HPLC) method was established to rapidly and simultaneously determine 3 main alkaloids (arecoline, arecaidine, and guvacine) in areca (betel) nuts (AN), and 12 AN samples from the main betel palm growing areas on the Chinese Mainland were collected and determined. Semen samples from acceptable volunteers were treated in vitro with different concentrations of the 3 alkaloids to evaluate the effects on sperm motility (SM). Highly motile spermatozoa were selected from the samples and divided into 5 equal fractions. Various concentrations of each alkaloid were added to 4 of the 5 fractions, and 1 fraction was used as a control. All fractions were incubated for 4 h. A computer-aided sperm analysis system was used to measure 5 SM parameters, motility, average path velocity, straight-line velocity, curvilinear velocity, linearity, and amplitude of lateral head displacement. The results showed that the contents of the amount of alkaloids in AN differed markedly in different places in China and were higher in the kernel than in the husk, and higher in dried AN than in fresh AN. Arecoline had the strongest reduction effect on human SM and the effect was strongly dose dependent. Arecaidine had a much weaker reduction effect than arecoline, and guvacine had the least reduction effect. These findings also demonstrate that betel quid could have adverse effects on the gonadal functions of betel quid consumers.

Abstract
Areca nut (Areca catechu) is chewed regularly as a medical and psychoactive food by about 10% of the world population, in countries including India, Taiwan and parts of Southern Asia. Areca nut chewing during pregnancy has been associated with both lower birth weight and premature birth. Animals of low birth weights showed retardation of muscle development. Our previous study showed that arecoline, the major areca alkaloid, decreased the number of implanted embryos. Here we sought to determine the effects of arecoline in myogenic differentiation by in vitro assays using C2C12 myoblast cells. The results showed that arecoline higher than 0.4mM significantly increased apoptosis and decreased viability of C2C12 cells. Morphometric measurements of myotube formation and analyses of myogenic markers, myosin heavy chain and myogenin, revealed that myogenic differentiation was inhibited by 0.04-0.08 mM arecoline. Moreover, phosphorylated but not total STAT3 was significantly inhibited by arecoline during myotube formation. These results indicate that arecoline inhibits the myogenic differentiation of C2C12 cells by reducing the activation of STAT3, an upstream regulator of myogenesis. Improved understanding of the effects of arecoline during myogenic differentiation may help to establish public health policies and to develop potential treatments for such patients.

Abstract
Few studies have investigated whether genetic abnormalities predispose individuals to heavy betel quid (BQ) use. One of the major ingredients of BQ, arecoline, is known to affect the expression of monoamine oxidase A (MAO-A). We investigated the extent to which arecoline inhibits MAO-A expression and the role of MAO-A polymorphisms in BQ use in Taiwanese aborigines. Cytotoxicity assays, microarrays and quantitative reverse transcriptase-polymerase chain reaction were used to examine the effects of arecoline and areca nut extract (ANE) on cell viability and MAO-A expression in neuroblastoma SH-SY5Y cells. After identifying the effective concentrations of arecoline and ANE in vitro, we examined the in vivo effects of these compounds using a rat model system. Our results indicate that arecoline and ANE inhibit MAO-A expression both in vitro and in vivo. In addition, we examined the correlation between plasma MAO-A activity and cumulative exposure to BQ in humans. We recruited 1307 aborigines from a large-scale community-based survey to determine whether MAO-A variants were associated with high BQ use and a preference for use with smoking or alcohol and whether gender bias existed. MAO-A expression was significantly downregulated by arecoline and ANE at 100-200 µg/ml and in rat whole brains on days 30 and 45. MAO-A activity levels in human plasma were positively correlated with the extent of BQ exposure, and individuals with at-risk alleles exhibited lower activity, although this result did not reach statistical significance. We found two single nucleotide polymorphism (SNPs) in aboriginal males [rs2283725, odds ratio (OR) = 2.04; rs5953210, OR = 2.03] and females (rs2283725, OR = 1.54; rs5953210, OR = 1.59) that were associated with heavy BQ use. Those individuals carrying at-risk alleles who drank alcohol were twice as likely to be heavy BQ users. However, the effects of these SNPs on BQ use were significant even after controlling for alcohol use. Our results suggest that two specific loci may confer a susceptibility to BQ abuse and affect MAO-A enzymatic activity.

EFFECTS OF AGE, ETHNICITY AND HEALTH BEHAVIOURS ON THE PREVALENCE OF ADVERSE BIRTH OUTCOMES IN TAIWAN. J Biosoc Sci 2012; 44:513-24.

Abstract
SummaryThis study sampled 8432 singleton first live births from Taiwan's 2005 Birth Registration Database to determine if there were more pre-term or low birth weight deliveries among aboriginal women than there were among Han Chinese women, and if the ‘weathering’ hypothesis applied to aboriginal women in Taiwan. Although the aboriginal women were socially disadvantaged and engaged in more unhealthy behaviours, including smoking, drinking, chewing betel quid and exposure to second-hand smoke, the evidence did not support the hypothesis that these teenaged minority women would have better birth outcomes, as has been demonstrated among teenage African-American women in the United States. Behaviours and not ethnicity were risk factors for teenage aboriginal mothers, who started deleterious health behaviours earlier than did their older counterparts. Teenage mothers had more adverse outcomes regardless of ethnicity and aboriginal mothers had more risky behaviours in all age groups. The prevalence of detrimental health behaviour among teenage mothers in Taiwan is of concern, particularly for aboriginal teenage mothers.

Abstract
BACKGROUND The development of betel-quid (BQ) processing industry in Hunan has increased the usage of this substance and may produce significant health consequences. However, the update data for the prevalence of BQ chewing and its effect on oral submucous fibrosis (OSF) are limited. METHODS A population-based survey was conducted to investigate the prevalence of BQ chewing and OSF in Hunan. A questionnaire interview and an oral examination were conducted. A multivariate logistic regression model was used to study the effect of socio-demographic characteristics on area-specific behaviors of BQ chewing. RESULTS A total of 2356 subjects participated in this survey, with a 78.5% of response rate. The lifetime prevalence of BQ chewing was 16.2% (2.9% for ex-chewers and 13.3% for current-chewers). The findings from multivariate logistic regression model showed that a higher prevalence of this habit was among individuals who were males, urban residents, 15-49 years old, educated for 9-12 years, smokers, and drinkers. Male chewers occupied a fairly higher percentage of the combined use of tobacco and/or alcohol (86.1-87.5%) than the non-chewers (50.6-56.7%). The overall prevalence of OSF was 1.0%. Compared with the subjects without OSF (1.7-23.2%), a significantly higher proportion of OSF patients were a current-chewer (62.3% in men and 100.0% in women). CONCLUSIONS BQ chewing is a vital risk factor for OSF in Hunan. A high prevalence of BQ chewing found among the younger cohort (15-49 years old) is an urgent warning for this oral premalignant disorder.

Abstract
To examine the rates and factors associated with alcohol consumption after the recognition of pregnancy among indigenous pregnant women, as well as the rates and factors associated with continuing alcohol consumption after the recognition of pregnancy among indigenous pregnant women who drank alcohol before the recognition of pregnancy in 10 hospitals in southern and eastern Taiwan. A total of 806 indigenous women who had just given birth in 10 hospitals in southern and eastern Taiwan were recruited. They were interviewed to collect their substance use information, demographic characteristics, psychological health status, history of physical abuse, and pregnancy history. The rates of alcohol consumption after the recognition of pregnancy in all indigenous pregnant women and the rates of continuing alcohol consumption after the recognition of pregnancy among those who drank alcohol before the recognition of pregnancy were calculated. The factors relating to alcohol consumption and continuing alcohol consumption after the recognition of pregnancy were examined using logistic regression analyses. The results of this study found that 26.6% of indigenous pregnant women drank alcohol at any stage after the recognition of pregnancy, and 52.5% of indigenous pregnant women who drank alcohol before the recognition of pregnancy persisted in drinking alcohol after the recognition of pregnancy. Multiple parities, smoking or chewing betel quid after the recognition of pregnancy, and a higher frequency of drinking alcohol before the recognition of pregnancy were significantly associated with alcohol consumption and continuing alcohol consumption after the recognition of pregnancy. Meanwhile, being single or divorced, and intimate partner violence after the recognition of pregnancy were significantly associated with alcohol consumption after the recognition of pregnancy. High prevalence rates of alcohol consumption and continuing alcohol consumption after the recognition of pregnancy were found among indigenous pregnant women in Taiwan. Early detection of alcohol consumption and effective intervention for alcohol consumption during pregnancy are needed.

Abstract
More than 100 studies have examined whether environmental or occupational exposures of parents affect the sex ratio of their offspring at birth. For this review, we searched Medline and Web of Science using the terms ‘sex ratio at birth’ and ‘sex ratio and exposure’ for all dates, and reviewed bibliographies of relevant studies to find additional articles. This review focuses on exposures that have been the subject of at least four studies including polychlorinated biphenyls (PCBs), dioxins, pesticides, lead and other metals, radiation, boron, and g-forces. For paternal exposures, only dioxins and PCBs were consistently associated with sex ratios higher or lower than the expected 1.06. Dioxins were associated with a decreased proportion of male births, whereas PCBs were associated with an increased proportion of male births. There was limited evidence for a decrease in the proportion of male births after paternal exposure to DBCP, lead, methylmercury, non-ionizing radiation, ionizing radiation treatment for childhood cancer, boron, or g-forces. Few studies have found higher or lower sex ratios associated with maternal exposures. Studies in humans and animals have found a reduction in the number of male births associated with lower male fertility, but the mechanism by which environmental hazards might change the sex ratio has not yet been established.

Abstract
AIM The adverse effects of areca nut (AN) chewing habit on oral health have been reported. However, the hazards related to the habit are not restricted to the oral cavity but they can also jeopardise the systemic health. Since no review reporting the harmful effects of AN chewing on systemic health is yet available, the aim of the present study was to review the systemic conditions associated with AN usage. METHODS To address the focused question ''What are the deleterious effects of AN usage on systemic health?'', the MEDLINE PubMed databases were explored from 1966 up to and including May 2010. The eligibility criteria included: human studies, individuals using AN, use of controls, and articles published in English. Hand-searching was also performed. Unpublished data was excluded. RESULTS The review included 28 articles. Seven studies associated AN chewing with cardiovascular disorders and three studies related the habit with cerebrovascular disorders. Eight studies related AN chewing with obesity, hyperglycaemia, metabolic syndrome, and type 2 diabetes mellitus. Five studies related AN chewing with the development of hepatic disorders. Two studies associated the chewing habit with oesophageal inflammation and fibrosis. Three studies associated AN chewing with respiratory discomfort. Renal disorders were related with the chewing abuse in two studies. Two studies showed an adverse effect of AN chewing on birth outcome. CONCLUSIONS AN chewing adversely affects systemic health by damaging the vital organs.

Abstract
Background Approximately 600 million people chew Betel nut, making this practice the fourth most popular oral habit in the world. Arecoline, the major alkaloid present in betel nut is one of the causative agents for precancerous lesions and several cancers of mouth among those who chew betel nut. Arecoline can be detected in the human embryonic tissue and is correlated to low birth weight of newborns whose mothers chew betel nut during pregnancy, suggesting that arecoline can induce many systemic effects. However, few reports exist as to the effects of arecoline in human tissues other than oral cancer cell lines. Furthermore, in any system, virtually nothing is known about the cellular effects of arecoline treatment on membrane associated signaling components of human cancer cells. Results Using the human Ishikawa endometrial cancer cell line, we investigated the effects of arecoline on expression, localization and functional connections between the ZO-1 tight junction protein and the HER2 EGF receptor family member. Treatment of Ishikawa cells with arecoline coordinately down-regulated expression of both ZO-1 and HER2 protein and transcripts in a dose dependent manner. Biochemical fractionation of cells as well as indirect immunofluorescence revealed that arecoline disrupted the localization of ZO-1 to the junctional complex at the cell periphery. Compared to control transfected cells, ectopic expression of exogenous HER2 prevented the arecoline mediated down-regulation of ZO-1 expression and restored the localization of ZO-1 to the cell periphery. Furthermore, treatment with dexamethasone, a synthetic glucocorticoid reported to up-regulate expression of HER2 in Ishikawa cells, precluded arecoline from down-regulating ZO-1 expression and disrupting ZO-1 localization. Conclusion Arecoline is known to induce precancerous lesions and cancer in the oral cavity of betel nut users. The arecoline down-regulation of ZO-1 expression and subcellular distribution suggests that arecoline potentially disrupts cell-cell interactions mediated by ZO-1, which may play a role in arecoline-mediated carcinogenesis. Furthermore, our study has uncovered the dependency of ZO-1 localization and expression on HER2 expression, which has therefore established a new cellular link between HER2 mediated signaling and apical junction formation involving ZO-1.

Abstract
In the present study, areca nut extracts (ANE) administered to male rats by gavage at a dose of 100mg/kg/day for a period of 15, 30, or 45 days resulted in signs of reproductive toxicity. ANE administration resulted in a significant decline (30-57% in epididymal sperm count and 27-61% in sperm motility) as well as substantial abnormalities in sperm morphology. Significant variances in activities of antioxidant enzymes were also observed. Malondialdehyde (MDA) levels, which represent the level of lipid peroxidation, increased by 16-188% and levels of sialic acid decreased by 2-46% compared with that in controls. These results indicate that ANE induced spermatogenic damage, as indicated by a decrease in sperm counts and sperm motility as well as the activity of antioxidant enzymes, an increase in sperm abnormalities, and alterations in sialic acid and MDA levels. Such effects reflect that ANE administration resulted in reactive oxygen species (ROS)-induced oxidative stress in the testis, cauda epididymis, and sperm of male rats.

Abstract
INTRODUCTION In Papua New Guinea, betel nut chewing is very common in the general population and in pregnant women. It has similarities in terms of use and complications of use to chewing tobacco (=smokeless tobacco), as its active agent, arecoline is similar to nicotine. The present study investigates the habits of betel nut chewing and possible impact on pregnancy. METHODS In a cross-sectional survey 310 pregnant women attending Alexishafen Health Centre (Madang Province) were interviewed with a survey measuring: detailed demographic data, betel nut chewing habits, other potential addictions (smoking, alcohol and drug use) and a medical examination (weight, height, blood pressure and hemoglobin level were recorded). Their babies have been assessed for birth weight and signs of prematurity. RESULTS Among pregnant women, 94% regularly chew betel nut, 9% smoke and 1% used alcohol. 31% are heavy chewers (>10 nuts/day). The principal reasons for pregnant women to chew are: to prevent morning sickness (28%), to prevent having a smelly mouth (26%), the habit of chewing (20%), being addicted (10%). Primigravidity, betel nut chewing and low BMI had a statistically significant impact on birth weight reduction of 467 g (p<0.001), 238 g (p=0.02) and 175 g (p=0.005) respectively. 80% of the women thought that chewing would not have any effect on the fetus. DISCUSSION Given the high use of "pure" betel nut among pregnant women, a significant impact on birth weight reduction and a poor knowledge about the adverse health effects of this substance, prevention programs in pregnant women should include betel nut chewing as a risk factor for poor pregnancy outcome.

Abstract
OBJECTIVE To identify the demographic characteristics of current tobacco users in Cambodia, particularly women, and to explore the reasons for current tobacco use in demographic subgroups of the Cambodian population. METHODS We used a stratified three-stage cluster sample of 13,988 adults aged 18 years and older from all provinces in 2005-2006. Participants completed an interviewer-administered survey that contained items on all forms of tobacco use and on health and lifestyle variables. Multivariable regression analysis was performed to identify demographic predictors of tobacco use. FINDINGS Cigarette smoking occurred among 48.0% of men and 3.6% of women. We estimated that 560,482 women (95% confidence interval, CI: 504,783 to 616 180) currently chewed tobacco (typically as a component of betel quid) and that the prevalence more than doubles with each decade of adulthood up to the point that about half of all older women chew tobacco. Both men and women cited the influence of older relatives as their primary reason for starting to use tobacco. About one out of five rural women who used chewing tobacco started their habit for relief from morning sickness. The highest prevalence of chewing tobacco among women was seen among midwives (67.9%) and traditional healers (47.2%). High rates (66.8%) of cigarette and pipe tobacco use occurred among ethnic minorities who represent hill tribes found throughout south-east Asia. CONCLUSION The tobacco epidemic in Cambodia extends far beyond cigarette smoking in men. Tobacco control that focuses only on cigarettes will not address the health burden from smokeless tobacco use in women that may be an integral part of cultural, familial, and traditional medicine practices.
