    This article aimed to identify the determinants of tobacco consumption and illegal drug use (IDU) as well as to examine the association between these two variables using a representative sample of 3,771 Bangladeshi males aged 15 to 54 years. Data were collected through Bangladesh Demographic and Health Survey 2007. To identify the determinants, the patterns of tobacco consumption and IDU were analyzed by age, education and occupation, residence, mass media, premarital sex, wealth, and sexually transmitted infections (STIs). Prevalence of smoking cigarette and bidi was roughly 60%. However, the prevalence of IDU was 3.4%, and this proportion is statistically significant (Z = 11.32, p = .000). After bivariate analysis, almost all variables except STIs were significantly associated with tobacco consumption. Similarly, all variables except residence and mass media were associated with IDU. Based on multivariable adjusted logistic regression analysis, the likelihood of using IDU was approximately twofold (odds ratio [OR] = 1.8, 95% confidence interval [CI] = 1.23-2.53) among bidi smokers and fourfold (OR = 3.8, 95% CI = 2.62-5.56) among cigarette smokers as compared with nonsmokers.

    Adolescent tobacco use (ATU) is on the rise worldwide and the problem is particularly severe in developing countries. Based on nationally representative data, this study aims to investigate the association between ATU and its possible correlates for Bangladesh, where the prevalence rate of ATU is high. The data set is extracted from the Global Youth Tobacco Survey for Bangladesh conducted in 2007. The survey collected information from a total of 3113 students from 52 schools, with a response rate of 100% at the school level, while a response rate of 88.9% was achieved from the students. Students covered in the survey were in grades 7, 8, 9, and 10, with age ranging from 11 to 17 years. The prevalence rate of ATU at the time of the survey was 8.4%, while 35.6% of the students had used at least a type of tobacco products before. Logistic regressions were used to obtain the odds ratios (ORs) in favor of ATU for each of the possible determinants and the confidence intervals (CIs) of these ratios. Use of tobacco among friends (OR = 3.46; CI = 2.37-5.05), the experience of seeing others smoking at home (OR = 2.10; CI = 1.36-3.22) or other places (OR = 1.6; CI = 1.02-2.57), receiving pocket money (OR = 7.6; CI = 4.59-13.28), receiving free tobacco from vendors (OR = 2.3; CI = 1.44-3.78), and exposure to advertisements and promotions of tobacco products (OR = 1.83; CI = 1.23-2.79) were associated with a higher likelihood of ATU. Increased awareness of health hazards of tobacco use through education in schools helped mitigate the problem of ATU. The findings of this study have ramifications for tobacco control prevention strategies in Bangladesh.

    This study examines the safe delivery practices of Bangladeshi women using data on 4905 ever-married women aged 15 to 49 years from the 2007 Bangladesh Demographic and Health Survey. Variables that included age, region of origin, education level of respondent and spouse, residence, working status, religion, involvement in NGOs, mass media exposure, and wealth index were analyzed to find correlates of safe delivery practices. More than 80% of the deliveries took place at home, and only 18% were under safe and hygienic conditions. The likelihood of safe deliveries was significantly lower among younger and older mothers than middle-aged mothers and higher among educated mothers and those living in urban areas. Economically better-off mothers and those with greater exposure to mass media had a significantly higher incidence of safe delivery practices. A significant association with religion and safe delivery practices was revealed. Demographic, socioeconomic, cultural, and programmatic factors that are strongly associated with safe delivery practices should be considered in the formulation of reproductive health policy.

    The present study was conducted to elucidate the genetic divergence and the phylogenetic relationships in the F. limnocharis complex from Bangladesh and other Asian countries such as Sri Lanka, Thailand, Malaysia, Taiwan and Japan by allozyme analyses. We used a total of 95 frogs of the F. limnocharis complex from these countries and F. cancrivora from the Philippines as an outgroup. Based on body size, the F. limnocharis complex from Bangladesh was divided into three distinct groups: large, medium and small types. Allozyme analyses were carried out with 28 loci encoding 20 enzymes and two blood proteins by horizontal starch-gel electrophoresis. When genetic distance was calculated, distinct divergence was found among the three types: mean genetic distance was 0.782 between the small and medium types, 1.458 between the large and medium types, and 1.520 between the large and small types. Phylogenetic trees based on genetic distance showed that all populations of Bangladesh small type strongly formed a cluster and were found to be most closely related to the Sri Lanka population; that all populations of Bangladesh large type formed a very strong cluster and were grouped with several populations from Thailand, Malaysia, Japan, and Taiwan; and that the medium type was segregated from all other groups. This may imply that each of the three types is a different species, and that the medium type is possibly an undescribed taxon.

    PURPOSE: To study the association of smoking with poor oral hygiene status and halitosis in a comparative cross-sectional study.

    MATERIALS AND METHODS: 100 smokers and 100 nonsmokers ages 18-50 years were recruited for this study in Kota Bharu, Malaysia. Oral hygiene (good/fair vs poor) was determined using the Simplified Oral Hygiene Index, and the halitosis level was measured using a Halimeter. Subjects were instructed to refrain from consuming foods containing garlic, onions, strong spices, alcohol and using mouthwashes 48 h prior to the examination. The halitosis levels were quantified by recording volatile sulphur compounds (VSCs) three times at 3-min intervals, resulting in a mean halitosis score. Various statistical analyses were performed, ranging from simple frequency analysis to multivariable modelling.

    RESULTS: The proportions of subjects with poor oral hygiene and high halitosis were 24.0% and 41.5%, respectively. According to bivariate analyses, both problems were significantly less frequent among younger adults (halitosis), females, subjects with higher education, those with adequate habits to maintain good oral hygiene, those who had recent dental visits and those self-reporting fewer health problems. The percentages of poor oral hygiene and high halitosis were significantly higher in smokers (p < 0.001). However, almost all these variables failed to show significance in the multivariate analyses, with the exceptions of smoking for both poor oral hygiene and halitosis, education for poor oral hygiene, and age, self-reported health problems and time since the previous dental visit for halitosis.

    CONCLUSION: These findings demonstrate a significantly higher level of halitosis and poorer oral hygiene in smokers than nonsmokers.

    Microbial fuel cells (MFCs) are considered as promising technology to achieve simultaneous wastewater treatment and electricity generation. However, operational and technological developments are still required to make it as a sustainable technology. In the present study, response surface methodology (RSM) was used to evaluate the effects of substrate concentration, co-culture composition, pH and time on the performance of co-culture (Klebsiella variicola and Pseudomonas aeruginosa) inoculated double chamber MFC. From the statistical analysis, it can be seen that the performance of MFC was not influenced by the interaction between the initial COD and time, pH and time, pH and initial COD, time and initial COD. However, the interaction between the inoculum composition and time, pH and the inoculum composition, initial COD and inoculum composition significantly influenced the performance of MFC. Based on the RSM results, best performance (power density and COD removal efficiency) was obtained when the inoculum composition, initial COD, pH and time were about 1:1, 26.690 mg/L, 7.21 and 15.50 days, respectively. The predictions from the model were in close agreement with the experimental results suggesting that the proposed model could adequately represent the actual relationships between the independent variables generating electricity and the COD removal efficiency.

    Environmental quality indicators are crucial for responsive and cost-effective policies. The objective of the study is to examine the relationship between environmental quality indicators and financial development in Malaysia. For this purpose, the number of environmental quality indicators has been used, i.e., air pollution measured by carbon dioxide emissions, population density per square kilometer of land area, agricultural production measured by cereal production and livestock production, and energy resources considered by energy use and fossil fuel energy consumption, which placed an impact on the financial development of the country. The study used four main financial indicators, i.e., broad money supply (M2), domestic credit provided by the financial sector (DCFS), domestic credit to the private sector (DCPC), and inflation (CPI), which each financial indicator separately estimated with the environmental quality indicators, over a period of 1975-2013. The study used the generalized method of moments (GMM) technique to minimize the simultaneity from the model. The results show that carbon dioxide emissions exert the positive correlation with the M2, DCFC, and DCPC, while there is a negative correlation with the CPI. However, these results have been evaporated from the GMM estimates, where carbon emissions have no significant relationship with any of the four financial indicators in Malaysia. The GMM results show that population density has a negative relationship with the all four financial indicators; however, in case of M2, this relationship is insignificant to explain their result. Cereal production has a positive relationship with the DCPC, while there is a negative relationship with the CPI. Livestock production exerts the positive relationship with the all four financial indicators; however, this relationship with the CPI has a more elastic relationship, while the remaining relationship is less elastic with the three financial indicators in a country. Energy resources comprise energy use and fossil fuel energy consumption, both have distinct results with the financial indicators, as energy demand have a positive and significant relationship with the DCFC, DCPC, and CPI, while fossil fuel energy consumption have a negative relationship with these three financial indicators. The results of the study are of value to both environmentalists and policy makers.

    To elucidate genetic divergence and evolutionary relationship in Fejervarya cancrivora from Indonesia and other Asian countries, allozyme and molecular analyses were carried out using 131 frogs collected from 24 populations in Indonesia, Thailand, Bangladesh, Malaysia, and the Philippines. In the allozymic survey, seventeen enzymatic loci were examined for 92 frogs from eight representative localities. The results showed that F. cancrivora is subdivided into two main groups, the mangrove type and the large- plus Pelabuhan ratu types. The average Nel's genetic distance between the two groups was 0.535. Molecular phylogenetic trees based on nucleotide sequences of the 16S rRNA and Cyt b genes and constructed with the ML, MP, NJ, and BI methods also showed that the individuals of F. cancrivora analyzed comprised two clades, the mangrove type and the large plus Pelabuhan ratu / Sulawesi types, the latter further split into two subclades, the large type and the Pelabuhan ratu / Sulawesi type. The geographical distribution of individuals of the three F. cancrivora types was examined. Ten Individuals from Bangladesh, Thailand, and the Philippines represented the mangrove type; 34 Individuals from Malaysia and Indonesia represented the large type; and 11 individuals from Indonesia represented the Pelabuhan ratu / Sulawesi type. Average sequence divergences among the three types were 5.78-10.22% for the 16S and 12.88-16.38% for Cyt b. Our results suggest that each of the three types can be regarded as a distinct species.

    STATEMENT OF PROBLEM: Prosthetic techniques commonly employed for the rehabilitation of edentulous patients might not be adequate in the treatment of patients with microstomia.

    PURPOSE: The purpose of this paper is to systematically review all the prosthetic techniques that have been used in the oral rehabilitation of patients with microstomia.

    MATERIALS AND METHODS: Data sources, including PubMed, Google Scholar, SCOPUS and Web of Science, were searched for case reports and case series published through September 2017. Three investigators reviewed and verified the extracted data. Only case reports and case series on prosthetic rehabilitation in microstomia patients published in the English language were considered eligible.

    RESULTS: A total of 212 records were identified from the database search. Forty duplicate records were removed. The remaining 172 articles were assessed for eligibility, and 139 articles were removed because they did not satisfy the inclusion criteria. A total of 34 cases (including 32 case reports and 1 case series) were finally included in the qualitative analysis. The review revealed the use of a modified impression technique with flexible and sectional trays to record impressions in patients with microstomia. Modified forms of oral prostheses ranging from sectional, flexible, collapsible and hinged dentures to implant-supported prosthesis were fabricated to overcome the limited mouth opening. The success of the prosthetic technique primarily depended on the extent of the microstomia and the nature of the cause of the microstomia.

    CONCLUSION: Even though the patient acceptance of the prosthetic techniques summarized in the systematic review were high, long-term success rates for each option could not be assessed because of the short follow-up time in most of the included case reports and series.

    There is a scarcity of research on suicidal phenomena in the Muslim world. Therefore, this study aimed at investigating the self-reported prevalence of suicidal thoughts, attempts and motives in 12 Muslim countries. A total of 8417 (54.4% women) university students were surveyed by means of a self-report questionnaire. Overall, 22% of the participants reported suicidal ideation and 8.6% reported attempting suicide. The odds of suicidal thoughts were elevated in Azerbaijan, Indonesia and Saudi Arabia, while reduced ORs were recorded in Egypt, Jordan, Lebanon and Malaysia. While odds of suicide attempts were high in Azerbaijan, Palestine and Saudi Arabia reduced odds ratios (OR) were detected in Indonesia, Iran, Jordan, Lebanon, Malaysia and Tunisia. Taking drugs and using a sharp instrument were the two most frequently used methods to attempt suicide. Only 32.7% of attempts required medical attention. Escape motives were endorsed more than social motives by participants who attempted suicide. Suicidal behaviors were more frequent in women than in men. Compered to men, fewer attempts by women required medical attention. Moreover, our results show that making suicide illegal does not reduce the frequency of suicidal behavior. Results from this comparative study show that suicidal thoughts and attempts are frequent events in young adults in countries where religious scripture explicitly prohibit suicide and the frequencies of nonfatal suicidal behavior show large variation in nations adhering to the same religion.
