The current condition of waste management in Dhaka is a clear manifestation of poor sanitation in less developed nations. The city has been experiencing waste dumping on a daily basis. The aim of this research is to minimize waste, eliminate water contamination as well as greenhouse gas (GHG) emission by producing electricity from waste. An experiment was performed on a collection of wastewater samples and it was found that high level of water contamination is brought by extensive waste water contamination. The study found that wastewater from Dhaka city contained a diverse array of chemicals including toxic and non-toxic heavy metals, nitrates, phosphates, sodium (Na+), potassium (K+), sodium sulphate (SO42-), Calcium (Ca2+), chloride (Cl-) and harmful polyaromatic hydrocarbons. A multivariate analysis was applied and the level of contamination was detected to exceed the World Health Organization (WHO) permissible limit in all areas. Software simulation was also used in data analysis. The study found that 90% waste collection rate and High tech solid waste incinerator plan could produce 262.125 MW electricity per day and potentially reduce 2.375 million tons GHG emission in total per year.

Background: There is a dearth of published literature that demonstrates the impact and effectiveness of school-based oral health education (OHE) program in Bangladesh and it is one of the most neglected activities in the field of public health. Keeping this in mind, the objectives of this study were to assess the effectiveness of OHE program in: 1) increasing oral health knowledge, attitude, and practices and 2) decreasing the prevalence of untreated dental caries among 6-8 grade school students in Bangladesh. Methods: This intervention study was conducted in Araihazar Thana, Narayanganj district, Bangladesh during April 2012 to March 2013. The total participants were 944 students from three local schools. At baseline, students were assessed for oral health knowledge, attitude and practices using a self-administered structured questionnaire and untreated dental caries was assessed using clinical examination. Follow up study was done after 6 months from baseline. McNemar's chi-square analysis was used to evaluate the impact of OHE program on four recurrent themes of oral health between the baseline and follow-up. Multiple logistic regression analyses were used to determine the impact of the intervention group on our outcome variables. Results: Significant improvement was observed regarding school aged adolescents' self-reported higher knowledge, attitude and practices scores (p < 0.001) at follow-up compared with baseline. The prevalence of untreated dental caries of the study population after the OHE program was significantly (p < 0.01) reduced to 42.5 %. Multiple logistic regression analyses showed that the OHE intervention remained a significant predictor in reducing the risk of untreated dental caries (adjusted odds ratio [AOR] =0.51; 95 % confidence interval [CI] = 0.37, 0.81). In the follow-up period participants were 2.21 times (95 % CI = 1.87, 3.45) more likely to have higher level of knowledge regarding oral health compared to baseline. Compared with baseline participants in the follow-up were 1.89 times (95 % CI = 1.44-2.87) more likely to have higher attitude towards oral health. In addition, OHE intervention was found to be significantly associated with higher level of practices toward oral health (AOR = 1.64; 95 % CI = 1.12, 3.38). Conclusions: This study indicated that OHE intervention was effective in increasing i) knowledge, ii) attitude, and iii) practices towards oral health; it also significantly reduced the prevalence of untreated dental caries among school aged adolescents from grade 6-8 in a deprived rural area of Bangladesh.

Abstract: The present study aims to determine the quality of life (QOL) and general mental health of leprosy patients compared with the general population, and evaluate contributing factors such as socio-economic characteristics and perceived stigma. A total of 189 patients (160 outpatients, 29 inpatients) and 200 controls without leprosy or other chronic diseases were selected from Dhaka district, Bangladesh, using stratified random sampling. A Bangladeshi version of a structured questionnaire including socio-demographic characteristics—the Bangla version of the World Health Organization Quality of Life Assessment BREF (WHOQOL-BREF)—was used to assess QOL; a Self-Reporting Questionnaire (SRQ) was used to evaluate general mental health; the Barthel Index to control activities of daily living (ADL); and the authors’ Perceived Stigma Questionnaire was used to assess perceived stigma of patients with leprosy. Medical records were examined to evaluate disability grades and impairment. QOL and general mental health scores of leprosy patients were worse than those of the general population. Multiple regression analysis revealed that factors potentially contributing to the deteriorated QOL of leprosy patients were the presence of perceived stigma, fewer years of education, the presence of deformities, and a lower annual income. Perceived stigma showed the greatest association with adverse QOL. We conclude that there is an urgent need for interventions sensitive to the effects of perceived stigma, gender, and medical conditions to improve the QOL and mental health of Bangladeshi leprosy patients.

Abstract: This study aims to clarify the quality of life (QOL), mental health, and nutritional status of adolescents in Dhaka city, Bangladesh by comparing non-slum areas and slums, and to find the factors associated with their mental health problems. A sample of 187 boys and 137 girls from non-slum areas, and 157 boys and 121 girls from slums, between 11–18 years old were interviewed with a questionnaire consisting of a Bangla translation of the World Health Organization Quality of Life Assessment Instrument (WHOQOL-BREF), Self Reporting Questionnaire (SRQ), Youth Self-Report (YSR) and other questions. The height and weight of the respondents were measured. All significant differences in demographic characteristics, anthropometric measures, and WHOQOL-BREF were found to reflect worse conditions in slum than in non-slum areas. Contrarily, all differences in SRQ and YSR were worse in non-slum areas for both genders, except that the “conduct problems” score for YSR was worse for slum boys. Mental states were mainly associated with school enrolment and working status. Worse physical environment and QOL were found in slums, along with gender and area specific mental health difficulties. The results suggest gender specific needs and a requirement for area sensitive countermeasures. [Copyright &y& Elsevier]

The objectives of this study were to develop the Bangladesh version of the Youth Self-Report (YSR), and assess its reliability and validity in an adolescent population in Dhaka city, Bangladesh. One-hundred-and-eighty-seven boys (mean age: 14.6 years, SD: 2.1) and 137 girls (mean age: 15.2 years, SD: 2.0) from residential areas, and 27 boys (mean age: 17.0, SD: 1 .4) and 14 girls (mean age: 15.4, SD: 2.8) from a psychiatric hospital, all within the range of 11-18 years, were interviewed using a questionnaire that consisted of the Bangla translation of the YSR and other questions. Thirty-eight randomly selected adolescents were administered the same questionnaire one week after the first administration. All the core scores and most of the subscales showed high internal consistency other than small item-number subscales, and satisfactory test-retest reliability. Good discriminant validity was shown for most of the scale scores. This study showed that the Bangla translation of the YSR had sufficient reliability and validity for use in Bangladesh. The cutoff scores of the scales were higher for the Bangla version than for the original English version, and further studies exploring this point would be an asset. [ABSTRACT FROM AUTHOR]

The objectives of this study were to develop a Bangla version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF), and assess its reliability and validity on an adolescent population in Bangladesh. In total, 187 boys (mean age 14.6 years +/- SD 2.1) and 137 girls (15.2 +/- SD 2.0) from residential areas, and 157 boys (13.8 +/- SD 2.1) and 121 girls (13.4 +/- SD 2.1) from slums in Dhaka were interviewed using a questionnaire, which included a Bangla translation of the WHOQOL-BREF. Thirty-eight randomly selected adolescents from the original interviewed group were re-administered the same questionnaire 1 week later. On the whole, the Bangla version of WHOQOL-BREF showed good internal consistency and test-retest reliability. In comparisons between residential and slum areas, discriminant validities were observed in the total and environmental domain of both genders and in the social relationship domain of males. Furthermore, discriminant validities of physical and psychological domains were observed in gender comparisons. These results suggest that the Bangla version of WHOQOL-BREF is valid and reliable in assessing the quality of life of adolescents in Bangladesh. [ABSTRACT FROM AUTHOR]

The Paleoproterozoic (1.7 Ga) basement rocks from Maddhapara, Bangladesh show a large range of chemical variations (e.g. SiO 2 = 50.7–74.7%) and include diorite, quartz diorite, monzodiorite, quartz monzonite and granite. The pluton overall displays metaluminous, calc-alkaline orogenic suite; mostly I-type suites formed within subduction-related magmatism. The observed major elements show general trends for fractional crystallization. Trace element contents also indicate the possibility of a fractionation or assimilation; explain the entire variation from diorite to monzonite, even granite. The pluton may have evolved the unique chemical features by a process that included partial melting of calc-alkaline lithologies and mixing of mantle-derived magmas, followed by fractional crystallization, and by assimilation of country rocks. The pluton shows evidence of crystal fractionation involving largely plagioclase, amphibole and possibly biotite. Some of the fractionated magmas may have mixed with more potassic melts from distinct parts of the continental lithosphere to produce granites and/or pegmatites. New geochronological results of granitic pegmatite (1722 ± 10 Ma) are indisputably consistent with diorite and tonalite and those data showing credible geochronological sequence (i.e., diorite – tonalite – granitic pegmatite). Identical Paleoproterozoic age (1.7 Ga) with distinctive magmatism of the Maddhapara basement rocks have agreeable relationship with the CITZ, India. The consistent magmatism is also common in the Transamazonian of South America, Trans-Hudson orogeny in North America, Bohemian Massif and the Svecofennian, Poland, have identified the sequential growth of the continent through the amalgamation of juvenile terrains, succeeded by a major collisional orogeny. Such Paleoproterozoic subduction-related orogens in Australia have similar counterparts in Antarctica and other part of the world. These types of Paleoproterozoic magmatism dominantly contributed to assemble, amalgamation and breakup of the enormous Columbia supercontinent. [ABSTRACT FROM AUTHOR]

The aim of the present study was to evaluate the validity and reliability of the Bangla version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF) in an adult population in Bangladesh. Approximately 200 adults in the Dhaka district were interviewed using a questionnaire containing the Bangla version of the WHOQOL-BREF, as well as questions related to sociodemographic data. To assess the reliability of WHOQOL-BREF, Cronbach's alpha was calculated, and test-retest reliability was evaluated using intraclass correlation coefficient (ICC) of the first and second administrations. For comparison, approximately 200 leprosy patients were also interviewed with the questionnaire to examine the discriminant validity between groups. On the whole, sufficient validity was observed, and the Bangla version of the WHOQOL-BREF was deemed to be valid and reliable in assessing the quality of life of an adult population in Bangladesh.

Stigmatization by the general population and their negative attitudes towards leprosy negatively impacts on patients' mental health, and so too does patients' perception of that stigma. The objective of this present study is to assess the depressive status of leprosy patients, the patient perception of that stigma, and its association with their depressive status in Dhaka, Bangladesh. Subjects were 140 patients, and a selected comparison group of 135 local people without any chronic diseases. To evaluate depressive status, the Center for Epidemiologic Studies Depression scale (CES-D) Bengali version was applied. The patient group's depressive status was significantly more severe than that of the comparison group. Depressive status of those who answered affirmatively was significantly more severe than that of those who answered negatively for three responses to questions: 1) 'I have been physically attacked by people', 2) 'I feel people regard me as strange' and 3) 'I have been refused the purchase of something by a shopkeeper'. The results showed that the depressive status in leprosy patients was greater than that of the general public. Further, actual experiences of discrimination based on stigma associated with the depressive status of leprosy patients. Mental health care for patients, regulation of discriminatory action and education that would decrease social stigma among the general population, especially people who might often have contact with patients, seem necessary to improve the mental health of Bangladeshi leprosy patients.
