Introduction: A caesarean delivery is a major surgery with risks of severe bleeding, scarring, infections, reactions to anesthesia and long-lasting pain. The aim of the study was to determine the predictors of caesarean delivery at hospitals in Rajshahi city, Bangladesh. Methods: Data was collected from 194 women who delivered at three private and one public hospital maternity wards in Rajshahi city between January and March 2013. A questionnaire was used to collect socio-demographic background of the mothers. Body mass index was computed to determine overweight and underweight status of the women. Results: The prevalence of caesarean delivery at the hospitals studied was 77.3%. Socio-demographic factors and nutrition status that were significantly associated with the type of birth delivery were considered as independent variables in a logistic regression model. Multiple logistic regression analysis showed that older women (age z 25 year) were more likely to undergo caesarean delivery than younger women. Women with higher education were more likely to have caesarean delivery as compared to women without formal schooling. Overweight women had a higher likelihood of caesarean delivery than women with normal weight and underweight. Conclusion: The study recorded a high prevalence of caesarean deliveries at the hospitals in Rajshahi city. Age, educational level and BMI status of the women were associated with caesarian deliveries.

INTRODUCTIONCephalic index (CI), the ratio of head breadth to head length, is widely used to categorise human populations. The aim of this study was to access the impact of anthropometric measurements on the CI of male Japanese university students.

METHODSThis study included 1,215 male university students from Tokyo and Kyoto, selected using convenient sampling. Multiple regression analysis was used to determine the effect of anthropometric measurements on CI.

RESULTSThe variance inflation factor (VIF) showed no evidence of a multicollinearity problem among independent variables. The coefficients of the regression line demonstrated a significant positive relationship between CI and minimum frontal breadth (p < 0.01), bizygomatic breadth (p < 0.01) and head height (p < 0.05), and a negative relationship between CI and morphological facial height (p < 0.01) and head circumference (p < 0.01). Moreover, the coefficient and odds ratio of logistic regression analysis showed a greater likelihood for minimum frontal breadth (p < 0.01) and bizygomatic breadth (p < 0.01) to predict round-headedness, and morphological facial height (p < 0.05) and head circumference (p < 0.01) to predict long-headedness. Stepwise regression analysis revealed bizygomatic breadth, head circumference, minimum frontal breadth, head height and morphological facial height to be the best predictor craniofacial measurements with respect to CI.

CONCLUSIONThe results suggest that most of the variables considered in this study appear to influence the CI of adult male Japanese students.

Introduction: The culture of Nile tilapia (Oreochromis niloticus) has become wide spread because of its high productivity over a short period of time. Its production partially fulfills the demand for food in rural people in Bangladesh. However, the accumulation of toxic heavy metals in the human body through consumption of fish contaminated by it causes various diseases. The aim of this study was to evaluate the bioaccumulation of five heavy metals, namely, cadmium (Cd), chromium (Cr), lead (Pb), nickel (Ni) and copper (Cu) in cultured Nile tilapia in the Noakhali region of Bangladesh. Methods: Fish were collected from three different fish farms in the Noakhali region and samples of gill, muscles and liver of tilapia were assayed for Cd, Cr, Pb, Ni and Cu using atomic absorption spectroscopy. Proximate composition of the tilapia was also determined. Results: Metal accumulation in different tissues was as follows: liver > gill > muscle. The accumulation of metals in the muscle, gill and liver was Ni > Pb > Cr > Cu > Cd, Pb > Ni > Cu > Cr > Cd and Pb > Cu > Ni > Cr > Cd, respectively. The bioaccumulation of lead was significantly increased in liver and gill while muscle showed the lowest value. Conclusion: It can be concluded that bioaccumulation of Pb, Cr and Ni in Nile tilapia in this study exceeds the permissible limits set for heavy metals by Food and Agriculture Organization (FAO) and International Atomic Energy Agency (IAEA)-407. This is potentially risky for consumers.

Objective: To analyze in-vitro antimicrobial activities of some ethno-pharmacologically significant medicinal plants (methanol extract) against the pathogenic microorganisms (Escherichia coli, Salmonella spp., Bacillus cereus, Staphylococcus aureus, Aspergillus niger and Candida albicans). Methods: The disc diffusion method was applied for antibacterial test and the poisoned food technique was applied for antifungal test. Results: The methanol extract of Terminalia chebula (bark), Phyllanthus acidus (fruits), Sarcochlamys pulcherrima (leaves) and Abelmoschus esculentus (fruits) had significant in vitro antibacterial activity angainst the entire test samples in comparison to standard drug ciprofloxacin. Most of the plant extracts showed low activity against Gram negative bacteria while potential activity against Gram positive bacteria. The antifungal activities of methanol extracts of these plants and standard drug griseofulvin were determined against two pathogenic fungi, and Polygonum lapathifolium (leaves) and Cinnamomum tamala (leaves) showed maximum activity, while Erioglossum rubiginosum (leaves) showed no antifungal activity. Conclusions: Further chemical and pharmacological investigations are required to identify and isolate chemical constituents responsible for these potential bioactivities and thus to determine their full spectrum of efficacy.
