The study aimed to determine the epidemiological, clinical characteristics, and etiology of adults aged ≥20 years presented with prolonged acute diarrhea (≥7 days). A total of 18,210 adults aged ≥20 years were enrolled in the Diarrheal Disease Surveillance System of icddr,b between 1993-2012 and included into the analysis. Of these, 17,631 (97%) had duration of diarrhea ≤6 days, 418 (2%) diarrhea presented with a duration of 7 - 13 days and rest 161 (1%) had history of diarrhea ≥14 days. A higher proportion of adult individuals who had duration of diarrhea ≥14 days (70% vs. 56%;p male. At least 73% of all patients used oral rehydration solution;but proportion was lower among prolonged acute diarrhea groups. Use of antimicrobials was higher among those with duration 7 - 13 days (81%) and ≥14 days (81%). Diarrhea lasting ≥14 days, 47% were suffering from chronic energy deficiency and 30% had history of smoking. Individuals with diarrhea ≥7 days less frequently presented with vomiting, watery stool, frequency of stool >10 times/24 hours, drowsy or lethargy, fast breathing, some or severe dehydration, received intravenous saline for initial corrections of dehydration and stayed for longer duration in hospital (≥24 hours) but more often presented with abdominal pain. Stool microscopic examination showed less frequent presence of red blood cells (36% vs. 44%;p = 0.043) and fecal leucocytes (50% vs. 59%;p = 0.029) among individuals with diarrhea ≥14 days compared to those with ≤6 days. None was infected with Vibrio cholerae (≥14 days) (3% for 7 - 13 days);however, isolation rate of Aeromonas was higher among adults with duration for ≥14 days (11%). Only 15% with ≥14 days were positive for Shigella contrary to 19% (7 - 13 days) and 56% (≤6 days). Differences in sociodemographic, clinical presentation and etiology varied with duration of diarrhea among adults.

There is scarcity of evidence-based information about socio-demographic as well as ailment factors associated with foster children in Bangladesh. Thus the aim of the present study was to determine the socio-economic, health and nutritional status of young foster children in urban Dhaka. A total of 208 (1%;n = 208/28,948) under-5 foster children were enrolled in the Diarrheal Disease Surveillance System of icddr,b between 1993-2012. Randomly selected under-5 children (n = 624) with a ratio of 1:3 were extracted and constituted as comparison group. Forty-three percent (n = 90) foster children were male. Lack of formal schooling of mother was higher among foster children compared to non-foster children (52% vs. 35%;p < 0.001). Higher proportion of foster children suffered from some or severe dehy-dration (60% vs. 47%;p = 0.001) and often received intravenous saline (12% vs. 5%;p = 0.002) in comparison to non-foster children. Significantly lower proportion of foster children had rotavirus diarrhea (26% vs. 43%;p < 0.001). In multivariate analysis, foster children were 2 times (95% CI: 1.31-4.32) more likely to be stunted and 194 times (95% CI: 82.25-457.76) more likely to be non-breastfed. Infants aged 6-11 months were 8 times (95% CI: 3.70-15.50) more likely to be foster compared to older children and probability of fostering was 7 times (95% CI: 3.96-13.33) higher among mothers with a median age of 25 years. The findings of our study clearly demonstrate the existing health and nutritional problems of foster children. Therefore, appropriate health and nutrition interventions are critical for foster children in Bangladesh.

Medicinal plants have been used by marginal communities to treat various ailments. However, the potential of endophytes within these bio-prospective medicinal plants remains unknown. The present study elucidates the endophytic diversity of medicinal plants（Caralluma acutangula, Rhazya stricta, and Moringa peregrina） and the endophyte role in seed growth and oxidative stress. Various organs of medicinal plants yielded ten endophytes, which were identified as Phoma sp.（6 isolates）, Alternaria sp.（2）, Bipolaris sp.（1）, and Cladosporium sp.（1） based on 18 S rD NA sequencing and phylogenetic analysis. The culture filtrates（CFs; 25%, 50%, and 100% concentrations） from these endophytes were tested against the growth of normal and dwarf mutant rice lines. Endophytic CF exhibited dose-dependent growth stimulation and suppression effects. CF（100%） of Phoma sp. significantly increased rice seed germination and growth compared to controls and other endophytes. This growth-promoting effect was due to the presence of indole acetic acid in endophytic CF. The gas chromatography/mass spectrometry（GC/MS） analysis showed the highest indole acetic acid content（（54.31±0.21） μmol/L） in Bipolaris sp. In addition, the isolate of Bipolaris sp. exhibited significantly higher radical scavenging and anti-lipid peroxidation activity than the other isolates. Bipolaris sp. and Phoma sp. also exhibited significantly higher flavonoid and phenolic contents. The medicinal plants exhibited the presence of bio-prospective endophytic strains, which could be used for the improvement of crop growth and the mitigation of oxidative stresses.

There is a scarcity of information examining the prevalence of overweight and obesity in the general population of Bangladesh. Thus, the present study aimed to estimate the changing trends and socio-demographic characteristics of overweight and obese individuals among an urban population inDhaka,Bangladesh. The present study included data from 49,532 patients enrolled in the Diarrheal Disease Surveillance System (DDSS) at theDhakaHospitalfrom 1993-2011. Overweight and obese was categorized among under-5 children (n = 508), 5 19 years (n = 96), and >19 years (n = 1330). Data was compared with normal weight and malnourished individuals of respective age strata. The proportion of overweight and obese increased from 0.64% 5.15% among children 0.001), 0.80% 6.70% among 5 19 years (p 0.001), and 3.66% 16.94% (p 0.001) among >19 years. Among those under-5, males [OR = 1.31 (95%CI 1.08, 1.57)] those with higher socio-economic status [1.99 (1.02, 3.82)], higher monthly mean family income [3.76 (2.41, 5.86)], non-slum residence [2.01 (0.74, 5.51)], high maternal literacy rate [3.66 (2.31, 5.79)], and using sanitary toilet [1.47 (1.07, 2.01)] were at higher risk of being overweight and obese compared to well-nourished and malnourished children. Among individuals 5 19 years, those with higher socioeconomic status and use of sanitary toilet were at higher risk of being overweight and obese. Among those >19 years, additionally males were less likely to be overweight and obese [0.59 (0.49, 0.68)]. Over the last two decades the prevalence of overweight and obesity in Dhaka city has increased at least five folds and it was much higher among those with better socioeconomic status.

Indian mustard (Brassica juncea L.) germplasm consisting 167 accessions including one check cultivar was evaluated for qualitative and quantitative traits. The present study was conducted to investigate genetic diversity and correlation among studied genotypes of B. juncea L. based on agro-morphological at NARC, Islamabad, Pakistan. To investigate the genetic diversity based on morphological characters, data was recorded on 20 quantitative and 12 qualitative traits. The calculated data was analyzed through two complementary methods, i.e. PCA (Principal Component Analysis) and cluster analysis. Among all the studied cultivars, significant diversity was recorded for different agro-morphological characters. Among all the parameters, maximum variance was recorded for pod shattering (427.2) followed by plant height (345.6), days to 100% flowering (336.2) and main raceme length (210.0). Among all the characters, the greatest and highly significant association (0.99) was found between days to maturity 50% and days to maturity 100% followed by correlation (0.86) among days to flowering 50% and days to flowering 100%, correlation value (0.71) was calculated among leaf length and leaf width. Using cluster analysis all the genotypes were divided into five major groups. It was observed that 7 out of 20 principal components with an Eigen value of ≥1.0 calculated for 73.92% of the total diversity observed between 167 accessions of Indian mustard (B. juncea L.). The contribution of first three PCs in the total PCs was 23.25, 12.87 and 11.24, respectively. Among all the investigated accessions two genotypes 26,813 and 26,817 showed great potential for seeds/silique, 1000-seed weight and seed yield/plant, respectively, so these genotypes are recommended for future breeding programs for achieving promising results.
