Abstract
Drug abuse is considered a global health problem with serious social impact. In recent decades, changes in drug consumption patterns have shown a clear rising trend in the use of multiple drugs. Although the buccal micronucleus cytome (BMCyt) assay has evaluated cytotoxicity in drug abuse, there has not been an approach that takes into account this pattern of multiple drug use. Therefore, in this study, we evaluate for the first time the cytogenotoxic effects in multidrug users, and its correlation with the amount consumed and years of abuse. This study was conducted on 166 individuals by the BMCyt assay. A total of 83 individuals with a history of multiple licit (alcohol and tobacco) and at least one illicit drug abuse (marijuana, methamphetamines, cocaine, and/or inhalants), and 83 healthy individuals, non-drug abusers were analyzed. The results showed that drug abusers had higher frequencies of nuclear abnormalities nuclear buds, binucleated cells, pyknotic nuclei (PNs), karyorrhexis (KX), and abnormally condensed chromatin when compared with healthy controls. Moreover, results suggests that the use of licit and illicit drugs is related to cytogenotoxic damage, as was shown by an upward trend in the frequency of nuclear abnormalities identified in groups 1 (alcohol + tobacco + at least one illicit drug) and 2 (tobacco + at least one illicit drug). Furthermore, a positive correlation was found in the different groups, between the years and the amount of consumption of some drugs (alcohol, methamphetamine, and tobacco) with cytotoxicity markers such as KL, KX, and PNs.

Abstract
OBJECTIVE The study examines the outcomes of pregnancies conceived at advanced maternal age (AMA) and maternal complications after childbirth among Meitei women of Northeast India. METHOD A total of 760 women participants were included in this study and compared among women aged ≥35 years, with a reference group of women aged 20-34 years. Data on obstetric characteristics were collected after obtaining consent. The data were compared using chi-square analysis, and the results were adjusted using a logistic regression model. Decision trees were developed to predict the potential variables associated with preterm delivery and postpartum complication. RESULTS In the study, 18.95% of AMA women experienced one or more adverse pregnancy outcomes (APOs). Women with AMA are at significantly increased risk of placenta previa (adjusted odds ratio [AOR] = 4.89, 95% confidence interval [CI]: 2.78-8.57), induction of labor (AOR = 3.69, 95%CI: 2.48-5.50), and caesarean section (AOR = 3.42, 95%CI: 2.28-5.12). Moreover, AMA women have a 1.86-2.76 AOR for developing gestational diabetes, pregnancy-induced hypertension, urinary tract infections, preterm delivery, and postpartum complications. Decision tree analysis revealed that AMA and urban residence independently predict preterm delivery and postpartum complications. CONCLUSION The study's findings confirm the adverse impact of AMA on pregnancy outcomes and postpartum complications. Such issues should be addressed, and counseling on the risk of AMA should be provided, particularly for those in the high-risk group. Further prospective studies are needed to understand other potential risk factors of APOs and the impact of AMA complications to prevent the associated burden.

Abstract
BACKGROUND India accounts for over 67% of chewing tobacco users globally and more than 50 million women in India chew tobacco. Chewing tobacco is documented to have negative effects on health of mother and foetus. This research was conducted to study the trends in chewing tobacco use among pregnant women in India, and identify factors associated with chewing tobacco use among pregnant women. METHODS We analyzed micro-data from two representative national surveys i.e., National Family Health Survey (NFHS)-4 (2015-16) & NFHS-5 (2019-21). A sample of 32,428 & 28,408 pregnant women were extracted from NFHS-4 & NFHS-5 respectively. Weighted prevalence and 95% confidence levels of chewing tobacco use were computed. State wide comparisons in chewing tobacco use were made. Employing binary logistic regression, adjusted odds ratios (AOR) were computed to identify factors associated with chewing tobacco use. RESULTS From NFHS-4 to 5 the prevalence of chewing tobacco use among pregnant women decreased from 4.0%(95% CI = 3.9-4.0) to 2.3%(95% CI = 2.2-2.4) respectively indicating a relative reduction of 42.5%. The highest prevalence remains to be in north-eastern India at 13.0%. Belonging to north-eastern region AOR = 7.0(95 %CI = 6.2-7.9), no-education AOR = 13.2(95 %CI = 10.5-16.5), poorest wealth index AOR = 6.7(95 %CI = 5.6-8.0) and belonging to scheduled tribe AOR = 2.6(95 %CI = 2.4-2.9) was significantly associated with chewing tobacco use among pregnant women. CONCLUSION From NFHS-4 to 5, chewing tobacco use during pregnancy has shifted more towards socio-economically vulnerable population. Targeted approaches with accessible and affordable tobacco cessation advice integrated to primary healthcare system are needed.

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.

Abstract
Introduction It is likely that a pregnant woman is more motivated and receptive to accepting healthy habits and practices if talked about the benefits to the fetus. When explained about the harmful effects of tobacco on the health of the baby, the mother can be encouraged to modify her tobacco consumption habits and work toward quitting tobacco. Aim Our aim was to study the effectiveness of brief counseling (5As)-Antenatal Tobacco Cessation Support Program among pregnant women availing antenatal care (ANC). Methodology A quasi-randomized study design was used to conduct the study. The participants were identified by screening during ANC visits, and women consuming tobacco were subjected to detailed history taking and very brief counseling with the help of 5A's framework. Results We found that Mishri was the commonest form of tobacco consumed by these women. Around 93.33% of the women consume Mishri, followed by 6.66% of women consuming chewing tobacco. The method of brief counseling made an impact in the cessation of tobacco consumption in 13.37% of the study subjects. Conclusion We conclude that the use of brief counseling and motivational interviewing is feasible in most settings without inhibiting the other important aspects of ANC or disrupting the patient flow.

Abstract
Smokeless tobacco use can lead to impairments of ovarian function, morphology, oocyte quality and hormonal regulation. Use of smokeless tobacco during pregnancy has adverse health effects on both the mother and fetus. Exposure to smokeless tobacco in utero has long term health consequences on offspring.
The habitual consumption of tobacco in its various form is widespread and a serious public health issue globally. In particular, the use of smokeless tobacco has increased substantially due to its easy availability and misconception that it is relatively harmless compared to smoking. Tobacco use has been well established from numerous studies as a causative agent of devastating illnesses such as cancer, insulin resistance, hypertension, acute respiratory disease, osteoporosis, etc. Limited but growing evidence have also suggested its role in adversely affecting reproductive capabilities and outcomes in women of reproductive age and during pregnancy. This paper provides an updated review on available literature regarding the negative effects of smokeless tobacco use on female reproductive health, during pregnancy and its adverse consequences on the offspring. Existing data suggests the association between chronic smokeless tobacco use and impairment of ovarian morphology and function, oocyte quality, hormonal perturbations, fetal development and long-term health effects on the fetus. Improved understanding of these issues can contribute to better awareness of the dangers of smokeless tobacco products.

Abstract
The presence of micronuclei in oral epithelial cells is considered a marker of genotoxicity, which can be identified using exfoliative cytology. The aim of this study was to investigate cytotoxic damage through the evaluation of micronuclei in the oral mucosa of smokers and e-cigarette users compared to nonsmokers. We obtained smears from the buccal mucosa of 68 participants divided in 3 groups (smokers, e-cigarette users and nonsmokers), which were further processed with Papanicolaou stain. The frequencies of micronuclei and micronucleated cells were recorded and statistically analyzed at a level of significance of p < 0.05. The mean micronuclei values per 1000 cells were 3.6 ± 1.08 for smokers, 3.21 ± 1.12 for e-cigarette users and 1.95 ± 1.05 for nonsmokers. The mean values of micronucleated cells per 1000 cells were 2.48 ± 0.91 for smokers, 2.39 ± 1.07 for e-cigarette users and 1.4 ± 0.68 for nonsmokers. Smokers and e-cigarette users had significantly higher values of micronuclei and micronucleated cells compared to nonsmokers, but there were no significant differences between smokers and e-cigarette users. We concluded that the micronuclei count can be used as an early indicator for alterations of oral mucosa and exfoliative cytology represents an accessible tool which could be applied for mass screening.

Abstract
Environmental tobacco smoke (ETS) has been recognized as a major health hazard by environmental and public health authorities worldwide. In Portugal, smoke-free laws are in force for some years, banning smoking in most indoor public spaces. However, in hospitality venues such as restaurants and bars, owners can still choose between a total smoke-free policy or a partial smoking restriction with designated smoking areas, if adequate reinforced ventilation systems are implemented. Despite that, a previous study showed that workers remained continuously exposed to higher ETS pollution in Lisbon restaurants and bars where smoking was still allowed, comparatively to total smoke-free venues. This was assessed by measurements of indoor PM2.5 and urinary cotinine, a biomarkers of tobacco smoke exposure, demonstrating that partial smoking restrictions do not effectively protect workers from ETS. The aim of the present work was to characterize effect and susceptibility biomarkers in non-smokers from those hospitality venues occupationally exposed to ETS comparatively to non-exposed ones. A group of smokers was also included for comparison. The sister chromatid exchange (SCE), micronucleus (MN) and comet assays in whole peripheral blood lymphocytes (PBLs) and the micronucleus assay in exfoliated buccal cells, were used as biomarkers of genotoxicity. Furthermore, a comet assay after ex vivo challenge of leukocytes with an alkylating agent, ethyl methanesulfonate (EMS), was used to analyze the repair capacity of those cells. Genetic polymorphisms in genes associated with metabolism and DNA repair were also included. The results showed no clear association between occupational exposure to ETS and the induction of genotoxicity. Interestingly, the leukocytes from non-smoking ETS-exposed individuals displayed lower DNA damage levels in response to the ex vivo EMS challenge, in comparison to those from non-exposed workers, suggesting a possible adaptive response. The contribution of individual susceptibility to the effect biomarkers studied was unclear, deserving further investigation.
