Risk Factors of Malnutrition in Under-5 Children of Slum Area in Dhaka City.

Malnutrition is a serious public health problem that has been linked to increase risk of morbidity and mortality in slums of Dhaka city and where the prevalence of malnutrition is very high. This study was conducted to evaluate the risk factors of malnutrition among under-5 children of selective slum area in Dhaka City. This cross sectional study was conducted from January 2016 to December 2019, among 500 under-5 children selected by random sampling technique from Agargaon and Beribadh slums of Dhaka city. Anthropometric measurements were taken using standard methods those were weight, height, MUAC and age. A questionnaire was ready for data collection containing episode of diseases, breast feeding status, complementary feeding, family size, family income, maternal education status, housing, source of drinking water etc in under-5 children. Data were analyzed by using SPSS version 21.0. Among 500 children from slums area, malnutrition was present in 220(44%) cases. Out of them 115(23%) children were wasted, 205(41%) children were stunted and 175(35%) children were underweight. Malnutrition was found significantly high among non-breast feed babies, who breast feed only for 6 months, in whom colostrum was not given and also when complimentary feeding was not given properly (p<0.05). Malnourished children were found significantly higher among illiterate mothers and those who used Kancha house (p<0.05). Wasting, stunting and underweight were more with increasing family size. There were a decreased number of malnutrition cases when family income rises. Diarrhoea and ARI was significantly associated with malnutrition (p<0.05). Large number of children in slum areas of Dhaka city was suffering from malnutrition. Malnutrition was significantly higher among children who did not get colostrum; non-breast fed and got improper complimentary feeding. Maternal illiteracy, living in Kancha house, large family size, family income and associated disease condition were also contributed to malnutrition.

Gold Standard Cholera Diagnostics Are Tarnished by Lytic Bacteriophage and Antibiotics.

A fundamental, clinical, and scientific concern is how lytic bacteriophage, as well as antibiotics, impact diagnostic positivity. Cholera was chosen as a model disease to investigate this important question, because cholera outbreaks enable large enrollment, field methods are well established, and the predatory relationship between lytic bacteriophage and the etiologic agent Vibrio cholerae share commonalities across bacterial taxa. Patients with diarrheal disease were enrolled at two remote hospitals in Bangladesh. Diagnostic performance was assessed as a function of lytic bacteriophage detection and exposure to the first-line antibiotic azithromycin, detected in stool samples by mass spectrometry. Among diarrheal samples positive by nanoliter quantitative PCR (qPCR) for V. cholerae (n = 78/849), the odds that a rapid diagnostic test (RDT) or qPCR was positive was reduced by 89% (odds ratio [OR], 0.108; 95% confidence interval [CI], 0.002 to 0.872) and 87% (OR, 0.130; 95% CI, 0.022 to 0.649), respectively, when lytic bacteriophage were detected. The odds that an RDT or qPCR was positive was reduced by more than 99% (OR, 0.00; 95% CI, 0.00 to 0.28) and 89% (OR, 0.11; 95% CI, 0.03 to 0.44), respectively, when azithromycin was detected. Analysis of additional samples from South Sudan found similar phage effects on RDTs; antibiotics were not assayed. Cholera burden estimates may improve by accommodating for the negative effects of lytic bacteriophage and antibiotic exposure on diagnostic positivity. One accommodation is using bacteriophage detection as a proxy for pathogen detection. These findings have relevance for other diagnostic settings where bacterial pathogens are vulnerable to lytic bacteriophage predation.

New miRNAs network in human mesenchymal stem cells derived from skin and amniotic fluid.

Mesenchymal stem cells (MSCs), isolated from different adult sources, have great appeal for therapeutic applications due to their simple isolation, extensive expansion potential, and high differentiative potential.In our previous studies we isolated MSCs form amniotic fluid (AF-MSCs) and skin (S-MSCs) and characterized them according to their phenotype, pluripotency, and mRNA/microRNAs (miRNAs) profiling using Card A from Life Technologies.Here, we enlarge the profiling of AF-MCSs and S-MSCs to the more recently discovered miRNAs (Card B by Life Technologies) to identify the miRNAs putative target genes and the relative signaling pathways. Card B, in fact, contains miRNAs whose role and target are not yet elucidated.The expression of the analyzed miRNAs is changing between S-MSCs and AF-MSCs, indicating that these two types of MSCs show differences potentially related to their source. Interestingly, the pathways targeted by the miRNAS deriving from Card B are the same found during the analysis of miRNAs from Card A.This result confirms the key role played by WNT and TGF-ß pathways in stem cell fate, underlining as other miRNAs partially ignored up to now deserve to be reconsidered. In addition, this analysis allows including Adherens junction pathways among the mechanisms finely regulated in stem cell behavior.

Importance of acetylator phenotype in the identity of Asian populations.

The Marma, Tripura, and Chakma are tribal populations of South Asian countries such as Bangladesh. The populations are thought to be immigrants who started moving from their original home in the Far East toward the west and south. We randomly selected 80 Marma, 53 Tripura, and 43 Chakma to determine acetylation capacity and acetylator phenotype. The mean acetylation capacities were 63% in the Marma, 65% in the Tripura, and 70% in the Chakma. The acetylator phenotype was bimodally distributed as fast and slow acetylator. The frequencies of fast acetylator were 83% in the Marma, 89% in the Tripura, and 88% in the Chakma. According to acetylation capacity, the tribes are different from the founder nontribal populations of Bangladesh. They identify themselves as having a separate single population origin. The frequency of fast acetylator predicted served as the acetylator status of the Far East Asian population. The segregation of populations by acetylator phenotype on geographic longitude might be appropriate for geonational identification of Asian populations.

Oyster mushroom reduced blood glucose and cholesterol in diabetic subjects.

It has been postulated that mushroom has beneficial effect of lowering blood glucose and cholesterol in diabetic subjects. The literature so far searched and found that there was no published data in this regard. This study was undertaken to assess the effect of reducing blood glucose, cholesterol and triglycerides in diabetic patients. Additionally, this study addressed whether there was any hepatic and renal toxicity of mushroom. This clinical investigation was conducted in BIRDEM hospital from July 2005 to January 2006. Eighty-nine subjects were recruited. Baseline investigations included height, weight, blood pressure (SBP, DBP), plasma glucose for fasting (FPG) and 2-h after-breakfast (2hPG), total cholesterol (T-chol), triglycerides (TG) and high-density lipoprotein (HDL-c). Twenty- four days' study constitutes 7-days mushroom, 7-days no mushroom and then 7-days mushroom. Investigations were done at the start and each after every 7-days. Thirty subjects (M / F = 17 / 13) followed to ensure full compliance with the designed protocol for 24 days. The mean (SD) age of the participants was 46.3 (10) years. Mushroom significantly reduced systolic and diastolic blood pressure (SBP, p<0.01; DBP, p<0.05). It also lowered both plasma glucose significantly (FPG & 2-hPG, p<0.001). Mushroom also lowered total cholesterol and TG significantly; whereas, there was no significant change in weight and HDL-c. When mushroom was withdrawn, there were significant increases of DBP, FPG, 2hPG, T-cholesterol and TG, whereas, no significant change was observed in weight, SBP and HDL-c. Restarting mushroom there was again significant reduction of blood glucose, TG and cholesterol. We conclude that mushroom significantly reduced blood glucose, blood pressure, TG and cholesterol of diabetic subjects without any deleterious effect on liver and kidney. The effect of mushroom may be investigated in a large sample for a longer duration to evaluate its efficacy and toxicity.

Prevalence of diabetes and impaired fasting glucose in urban population of Bangladesh.

We investigated the prevalence of type 2 diabetes (T2DM) and impaired fasting glycemia (IFG) and their risk factors in the urban population of Bangladesh. The study was carried out in Dhaka City Corporation with a population of 99,12,908 in 20,89,336 households distributed in 95 wards. Using a multistage cluster sampling, we investigated 5265 eligible participants of 20 age years and above for height, weight, waist-girth, hip-girth, blood pressure and fasting blood glucose. Body mass index (BMI) and waist-to-hip ratio (WHR) were calculated. We used WHO diagnostic criteria of 1999. The overall prevalence of T2DM was 11.2% and IFG was 5.9%. The age-standardized prevalence of T2DM (95% CI) was 10.5% (9.37-11.13) and IFG was 5.2% (4.51-5.84). Compared with the slum dwellers, the non-slum dwellers had significantly higher prevalence of both T2DM (7.4 vs. 13.4%, p<0.001) and IFG (4.1 vs. 7.4%, p<0.001). Logistic regression analysis showed that family history of diabetes, higher family income, sedentary lifestyle and higher quartiles of age, BMI and WHR were significantly related to diabetes. The prevalence of diabetes in the urban population has increased alarmingly in recent years. Older age, obesity, higher income, family history of diabetes and reduced physical activity were proved to be the significant risk factors for diabetes and IFG.

Type 2 diabetes and impaired fasting blood glucose in rural Bangladesh: a population-based study.

BACKGROUND: Diabetes is a fast expanding global health problem but more so in the developing countries. Therefore, it is of particular interest to study the epidemiological transition of the state and to identify the risk factors in order to recognize the extent of the problem. METHODS: A random sample of 5000 rural individuals (age >/=20 years) were included in a cross-sectional study. Fasting capillary blood glucose levels were measured from 4757 individuals. Height, weight, waist, hips including blood pressure and demographic information was collected. RESULTS: The study population was lean [mean body mass index (BMI) 19.4] with a low prevalence of type 2 diabetes but relatively high impaired fasting glucose. No relationship between type 2 diabetes and BMI in men, but an overall relationship was observed for women (P = 0.04) (data not shown). Age, sex, and waist/hip ratio appeared to be important risk factors for the occurrence of type 2 diabetes in this population. CONCLUSIONS: Low prevalence of type 2 diabetes and relative high impaired fasting blood glucose was observed. The factors associated with the occurrence of diabetes in this population appeared to differ than its known relations with BMI. This may indicate that the risk factors for type 2 diabetes are likely to differ in different population. Our results are likely to be in line with the Indian data suggesting that a revised guideline for anthropometric measures in the South Asian population is called for, in order to classify people at risk.

Diabetes and hypertension in pregnancy in a rural community of Bangladesh: a population-based study.

AIMS: Gestational diabetes mellitus (GDM) is associated with increased infant mortality. Diabetes and infant mortality is higher in Bangladesh but the prevalence of diabetes and hypertension in pregnancy is not known. Thus, this study addressed the prevalence of diabetes and hypertension in pregnancy. METHODS: We selected 10 villages randomly in a union council of Nandail subdistrict. Following a population census (n = 14 382: male/female = 7476/6906) on demography and marital status, we interviewed 2205 married women (18-44 years) for detection of pregnancy. Of a total of 172 pregnancies, we investigated 147 with a gestational age of 24-28 weeks for obstetrical history, clinical examination and blood pressure (BP). Fasting (FBG) and 2-h blood glucose (2hBG) were assessed by Hemocue cuvette. WHO diagnostic criteria were used. RESULTS: The overall prevalence (95% CI) of diabetes was 6.8% (1.88-9.32) and 8.2% (3.74-12.64) according to FBG and 2hBG, respectively. The crude prevalence of systolic and diastolic hypertension was 6.8 and 5.4%, respectively. The median (interquartile range) values for age, BMI and FBG of the participants were 25.0 (21.0-30.0) years, 19.5 (18.2-21.2) and 3.9 (3.6-4.3), respectively. The history of abortion, neonatal death and stillbirth was found in 19.9, 11.4 and 9.6%, respectively. The prevalence of GDM was higher among those with the history of stillbirth (15.4 vs. 6.0%) and neonatal death (11.8 vs. 6.2%) than those without. CONCLUSION: The prevalence of GDM in rural Bangladesh is comparable with any other population with higher prevalence of GDM. Increased morbidity and mortality among mothers and newborns in Bangladesh may, in part, be because of increased prevalence of GDM.

Fasting cut-offs in determining the prevalence of diabetes and intermediate glucose abnormality in a non-obese population.

The study was undertaken to compare the effect of ADA and WHO criteria for screening of diabetes mellitus (DM) and intermediate glucose abnormality (Impaired fasting glucose/Impaired glucose tolerance-IFG/IGT) and to explore an acceptable fasting cut-off in a population-based study. Ten suburb villages with a population of 11,895 were selected purposively. Of the total 6235 eligible (> or = 20y) subjects, 4144 volunteered. We took height, weight, hip- and waist-girth, blood pressure and fasting blood glucose (FBG). All participants were classified into Group-1 (Gr-1: n=453) and Group-2 (Gr-2: n=3691), based on FBG above and below 5.4 mmol/l, respectively. All from Gr-1 and 610 randomized subjects from Gr-2 were investigated for oral glucose tolerance test (OGTT), HbA1c and lipids. The mean (SD) of age, body mass index (BMI) and FBG of all participants was 37.6 (15.2) y, 19.4 (2.9), and 4.7 (0.9) mmol/l, respectively. The prevalence of diabetes and IFG/IGT using American Diabetes Association (ADA) criteria were compared with WHO criteria separately in Gr-1 and Gr-2. For group-1, ADA criteria could diagnose 5.9% as diabetes and 2.1% as IFG, whereas, WHO criteria diagnosed 11.5% diabetes and 19% IGT. Likewise, in Gr-2, ADA detected much less than WHO criteria (DM: 0.3 vs. 2.3%; IFG/IGT 1.0 vs. 14.6%). We compared fasting and 2 hours post-load glucose (2-hBG) values according to percentiles. We found that 11.1 of 2-hBG corresponded with a fasting value that lies between 90 to 95th percentile, equivalent to 5.1-5.7 mmol/l. Using receiver operating characteristics (ROC) curve, we determined the cut-offs 4.6 - 5.4 mmol/l for IFG and > or = 5.5 for diabetes. Taking age and BMI into account the kappa agreements were better between the estimated cut-offs and the given 2-hBG values. The ADA cut-offs were found ineffective for screening. We proposed the modified fasting cut-offs for screening IFG and diabetes among the non-obese population.

Waist-to-height ratio is a better obesity index than body mass index and waist-to-hip ratio for predicting diabetes, hypertension and lipidemia.

Body mass index (BMI, kg/m.sq) and waist-to-hip ratio (WHR) are widely used as obesity indices for diabetes and cardiovascular risks. Lower adult height was related to diabetes and stroke. Waist-girth was proved important for visceral obesity. Incorporating waist-girth and height as waist-to-height ratio (WHtR), we reported earlier--"Waist-to-height ratio is an important predictor of hypertension and diabetes". We readdressed this index in a larger sample with two-sample OGTT and lipid profiles. In a cluster sampling of 16,818 rural inhabitants, considering age > or = 20 y, 5713 subjects were found eligible. Of them, 4923 (M/F=2321/2602) volunteered for height, weight, blood pressure, waist-girth and hip-girth. Fasting venous blood (5 ml) was drawn for plasma glucose, total cholesterol (T-chol), Triglycerides (TG) and high-density lipoprotien (HDL-c). Overall, 1565 participants were undertaken for OGTT. The mean (SD) values of BMI, WHR and WHtR for subjects with diabetes and hypertension were significantly higher in either sex. The level significance was highest for WHtR. The prevalence of diabetes and hypertension increased significantly with higher quintiles of BMI, WHR and WHtR (chi sq values were largest in WHtR for both events). Partial correlation coefficients, controlling for age and sex, showed that BMI, WHR and WHtR significantly correlated with systolic and diastolic BP, FBG, T-chol and TG. In the entire correlation matrix, the 'r' values were the highest for WHtR. Taking diabetes and hypertension as dependent variables, logistic regression also showed the highest odds ratio in higher WHtR than BMI and WHR. We conclude that WHtR was proved again a valuable obesity index for predicting diabetes, hypertension and lipidemia.

Prevalence of hypertension in Bangladesh: effect of socioeconomic risk factor on difference between rural and urban community.

Several studies reported that migrant Bangladeshis had greater risk for hypertension, diabetes and coronary heart disease compared with the Europeans and other migrant South Asians. So far, there has been no such study among the native population. This paper reports the hypertension prevalence and related risks among native Bangladeshis. A total of 2,361 subjects over 20 years of age were investigated. Overall prevalence rates of systolic and diastolic hypertension in the study population were 14.4 and 9.1 percent respectively. The prevalence of systolic hypertension was significantly higher in rural than in urban participants (P < 0.001). Compared with the poor the rich class had significantly higher prevalence of both systolic (P = 0.002) and diastolic (P = 0.041) hypertension. With increase of age, body mass index (BMI) and blood glucose level were significantly related to hypertension (P < 0.0001); whereas the trend for increasing waist-to-hip ratio (WHR), adjusting for social class, was not significant. Regression analysis showed that age, BMI, rural area and rich class were the strong predictors for hypertension. This study explored that hypertension prevalence in the native Bangladeshis is almost comparable to that of other Asian populations and South Asian migrants.

Genetic background of diabetic and nondiabetic sibs in young Bangladeshis.

The prevalence of diabetes mellitus in the young is higher in Bangladesh like other Asian developing nations. Albeit, undernutrition has been shown to be associated with diabetes in the young, not all such individuals are diabetic. Diabetes Mellitus is a multigenic disease. In IDDM, DR3/4 heterozygotes were shown to have a greatly increased risk of developing the disease, suggesting the concept of genetic factor(s) being involved in the development of diabetes. Therefore, this study was undertaken to determine the distribution of HLA class II alleles (DRB) and to identify the HLA associated risk for developing diabetes mellitus in the young Bangladeshis. A total of fifty individuals were investigated. Half of them (n=25) were diabetic patients, registered in BIRDEM and half the participants were their non-diabetic sibs. A genomic DNA PCR and Enzyme Linked Probe Hybridization Assay (ELPHA, Bio-test, Germany) was used to determine HLA class II alleles (DRB1, DRB 3, 4, 5) by in vitro amplification of DRB gene. Among all the sero-equivalent antigens found in the study subjects, the prevalence of DR15 (DR2) was overrepresented, both in the diabetic subjects and in their non-diabetic sibs. Moreover, compared with the non-diabetic group the diabetic patients showed higher frequency of DR15 alleles (39 and 25%) though the difference was not significant (chisq. 1.7, p>0.05). Next to DR15, DR4 was the most prevalent HLA-DRB gene found in the study population. Interestingly, the frequency of DR4 was higher in the diabetic than in the non-diabetic group (20 vs. 14%). The study showed that the DR15 and DR4 were the most prevalent in the study population. Moreover, DR7 though not very significant, was higher in non-diabetic compared to their diabetic sibs. Comparison between the diabetic and non-diabetic sibs could have been interesting and significant but we could not confirm our findings, possibly, due to small sample size. A study in a larger paired sample of unrelated population is also needed to substantiate our findings, and also to prove the susceptibility or resistant haplotype in the young diabetic subjects.

Blood pressure and coronary heart disease in NIDDM subjects at diagnosis: prevalence and risks in a Bangladeshi population.

Overall obesity and central fat distribution are frequently accompanied by hyperglycemia, hypertension (HTN) and coronary heart disease (CHD) observed in developed nations and in South Asian migrants. This study attempts to estimate the prevalence of CHD and HTN and to assess the related risks among the newly diagnosed diabetics in the developing communities. From a total of 3583 non-insulin-dependent diabetes mellitus (NIDDM) and impaired glucose tolerance (IGT) subjects, the authors investigated 693 (M = 295, F = 398) randomly selected non-smokers of age 30-60 years. WHO diagnostic criteria were used for NIDDM and IGT. Systolic and diastolic hypertension (sHTN and dHTN) were defined as systolic blood pressure (SBP) > or = 140 and diastolic (DBP) > or = 90 mmHg. Diagnosis of CHD was based on electrocardiogram either on rest or on stress or both when equivocal. The overall prevalence of CHD in the NIDDM subjects was 18.6%. The prevalence rates of sHTN and dHTN were 23.2 and 13.6%, respectively. CHD and HTN did not differ significantly between male and female and between urban and rural subjects. CHD prevalence was significantly higher in the higher tertiles of age, SBP and DBP (P < 0.001, for all cases). Logistic regression showed that only the increasing age, high waist-to-hip ratio (WHR) and high BP were the independent risks for CHD. For sHTN, the independent risks were increased age and high body mass index (BMI) (kg/m2). Regardless of sex and area, increased prevalence of CHD and HTN were found in the newly diagnosed diabetic subjects. Increased age, central obesity and HTN were the independent risks for CHD while advancing age and overall obesity was related to sHTN.

Prevalence of diabetes in a suburban population of Bangladesh.

To determine the prevalence of diabetes and hypertension, 6847 subjects of age 15 years or older, were investigated in a suburban population in Bangladesh. Fasting and post-prandial (capillary) blood glucose (2-hPG) was estimated. According to WHO criteria the crude prevalence of impaired glucose tolerance (IGT) was 7.5% and non-insulin-dependent diabetes mellitus (NIDDM) was 4.1%. The age standardized (30-64 years) prevalence of IGT was 7.7% with 95% confidence interval (CI) 6.96-8.44 and NIDDM was 4.5%, CI 3.94-5.12. Compared with the younger subjects the older subjects (< 40 vs. > or = 40 years) showed significant association with IGT (chi2, 65.9; P < 0.001) and NIDDM (chi2, 92.0; P < 0.001). Higher BMI (< or = 22.0 vs. > 22.1) was also significantly associated with IGT (chi2, 16.6; P < 0.001) and NIDDM (chi2, 83.9; P < 0.001). The higher BMI had stronger association with NIDDM than with IGT. Lower height showed significant association only with NIDDM. The logistic regression analyses also showed that increased age, higher BMI and short stature were independent risks for NIDDM. The study showed an increased prevalence of IGT and NIDDM among the suburban population of Bangladesh and the excess risk was observed with increased age, higher BMI and short stature.

Chemotherapy of acute myeloblastic leukaemia with DAM regimen.

32 patients of denovo-ANLL were treated with Doxorubicin, Ara-C and 6-Mercaptopurine (DAM) regimen. Remission induction was instituted with 1-3 cycles of DAM regimen and maintenance was given by 6-MP continuously with intermittent DA (1,5) regimen. In the remission induction, Doxorubicin 30 mg/m2 for 3 days, Ara-C 150 mg/m2 for 5 days and 6-Mp 100 mg/m2 daily was given. Complete remission (CR) was observed in 60% cases. The probability of 2 years disease-free survival of patients with complete remission is 56.73%.

Blood pressure and glycemic status in relation to body mass index in a rural population of Bangladesh.

A cluster sampling of five villages in Dohar thana were selected for screening of hypertension and diabetes in relation to age structure and body habitus. All the subjects over 15 years of age were enlisted for investigation. The response rate was more than 70%. Height, weight, blood pressure (BP) and capillary blood glucose (fasting and 2-hPG) were measured. Diagnostic criteria of international standard were used for hypertension and diabetes. Out of 1005 participants 106 subjects (10.5%) had systolic blood pressure (sBP) more than 140 mmHg and 9% of them had diastolic blood pressure (dBP) more than 90 mmHg. The prevalence of non-insulin-dependent diabetes mellitus (NIDDM) was 2.1% and impaired glucose tolerance (IGT) was 13.3%. The mean body mass index (BMI) of men was 20.39 (SD = 2.91) and that of women was 20.11 (SD = 2.92), having no significant difference between them. Increased age (> or = 50 yr), high BMI (> or = 23.0) and hyperglycemia (2-hPG > 7.8 mmol/L) were the risk factors for both systolic (sBP > 140 mmHg) and diastolic (dBP > 90 mmHg) hypertension. Likewise, increased age, high BMI and hypertension showed significant association with glucose intolerance. Moreover, significant correlations were observed between age and BP (sBP, r = 0.328 p < 0.001; dBP, r = 0.187 p < 0.001) BMI and BP (sBP, r = 0.193 p < 0.001; dBP, r = 0.192 p < 0.001) and 2-hPG and BP (sBP, r = 0.188 p < 0.001; dBP, r = 0.134 p < 0.001).
