ABSTRACT
Malnutrition is recognized to be a serious and common complication of chronic kidney disease (CKD) and is associated with increased morbidity and mortality in children. Early identification and swift intervention is the key in the management of malnutrition in CKD. The objective of the study was to determine the prevalence of malnutrition in children with CKD, to see the prevalence of malnutrition according to different anthropometric indices, to see the prevalence of malnutrition in different stages of CKD, to compare the nutritional status of children with CKD according to chronological age and height age. This analytical cross sectional study was done in the Department of Pediatric Nephrology of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from March 2014 to May 2015. Thirty children were enrolled in the study by purposive sampling. Nutritional assessment was done from dietary assessment by 72 hours recall and anthropometric measurements. Anthropometric indices were expressed in Z-scores and percentiles according to both chronological age and height age. Numeric data was analyzed by ANOVA and categorical data was tested by chi-square test. Difference between proportions was tested by Z-test of proportion. P value (<0.05) was considered significant. Data shows that the mean age of the studied population was 10.99±3.5 years with a male predominance. Eighteen (60.0%) children were on hemodialysis and rests on conservative management. Average calorie intake was 74.31±9.34% of estimated energy requirement (EER). The prevalence of malnutrition was 70.0% (95% CI: 53.6-86.4) according to height Z-score (HAZ), 66.7% (95% CI: 45.8-80.2) for weight Z-score (WAZ) and mid upper arm circumference (MUAC) Z-score, according to BMI percentile it was 56.7% (95% CI: 39-74.4), for mid arm muscle circumference (MAMC) the prevalence was 53.3% (95% CI: 35.5-71.1), according to arm muscle area (AMA) and arm fat area (AFA) the prevalence was 50.0% (95% CI: 38.1-67.9) and for triceps skin fold thickness (TST) it was 43.3% (95% CI: 25.5-61). Height was the most affected parameter and triceps skin fold thickness was the least affected parameter. When anthropometric indices were adjusted for height age, the prevalence was 36.7% according to BMI and TST, 30.0% according to AFA, 13.3% according to MUAC, 10.0% each for MAMC and AMA and 3.3% for WAZ. The difference in the prevalence of malnutrition according to this two approach was statistically significant in all parameters accept BMI, TST and AFA. Malnutrition was more associated with advanced stage of CKD. Low calorie intake was associated with low BMI and low serum albumin level. Serum albumin level was low in the present study population. In conclusion, prevalence of malnutrition is very high in children with CKD.

This study is aimed to assess the heavy metals contamination and health risk in Shrimp (Macrobrachium rosenbergii and Penaeus monodon) collected from Khulna-Satkhira region in Bangladesh. The results showed that the Pb concentrations (0.52-1.16 mg/kg) in all shrimp samples of farms were higher than the recommended limit. The Cd levels (0.05-0.13 mg/kg) in all samples and Cr levels in all farms except tissue content at Satkhira farm were higher than the permissible limits. The individual concentration of Pb, Cd, and Cr between shrimp tissue and shell in all rivers and farms were not statistically significant (P > 0.05). Target hazard quotient (THQ) and hazard index (HI) were estimated to assess the non-carcinogenic health risks. Shrimp samples from all locations under the current study were found to be safe for consumption, the possibility of health risk associated with non-carcinogenic effect is very low for continuous consumption for 30 years.
ABSTRACT
Regulation of stomatal aperture is crucial in terrestrial plants for controlling water loss and gaseous exchange with environment. While much is known of signaling for stomatal opening induced by blue light and the role of hormones, little is known about the regulation of stomatal closing in darkness. The present study was aimed to verify their role in stomatal regulation in darkness. Epidermal peelings from the leaves of Commelina benghalensis were incubated in a defined medium in darkness for 1 h followed by a 1 h incubation in different test solutions [H2O2, propyl gallate, ethrel (ethylene), AgNO3, sodium orthovanadate, tetraethyl ammonium chloride, CaCl2, LaCl3, separately and in combination] before stomatal apertures were measured under the microscope. In the dark stomata remained closed under treatments with ethylene and propyl gallate but opened widely in the presence of H2O2 and AgNO3. The opening effect was largely unaffected by supplementing the treatment with Na-vanadate (PM H+ ATPase inhibitor) and tetraethyl ammonium chloride (K(+)-channel inhibitor) except that opening was significantly inhibited by the latter in presence of H2O2. On the other hand, H2O2 could not override the closing effect of ethylene at any concentrations while a marginal opening of stomata was found when Ag NO3 treatment was given together with propyl gallate. CaCl2 treatment opened stomata in the darkness while LaCl3 maintained stomata closed. A combination of LaCl3 and propyl gallate strongly promoted stomatal opening. A probable action of ethylene in closing stomata of Commelina benghalensis in dark has been proposed.

In order to find out the fluctuation of pain by weather change, a descriptive cross-sectional study was conducted among 138 individuals having musculoskeletal disorders (MSDs) attending the out patient department (OPD) of Physical Medicine and Rehabilitation, Bangabandhu Sheikh Mujib Medical University (BSMMU) Hospital, Dhaka, during March 2004 to June 2004. Data were collected by face to face interview employing a pre-tested interview schedule containing structured questions. Among 138 respondents, male were predominant (52.2%). Mean age of the respondents was 39.42±10.79 years, while the most common age group was found as '31 to 40 years'. By occupation, majority were housewives (40.58%), followed by businessmen (29.71%), service holder (15.22%), laborer (7.97%), and students (6.52%). The primary sites of pain were back and low back (38.4%), knee (24.6%), leg (8.7%), ankle and heel (8.0%), hand and wrist (6.5%), neck (5.8%), shoulder (5.8%), and elbow (2.2%). Highest number (47.8%) patients reported aching pain, while one fifth (20.3%) of them experienced burning pain. About 36.2 percent respondents mentioned 'prolonged standing' as the main cause of pain aggravation, while almost half (48.6%) of the patients perceived that 'application of heat' was the key relieving factor of their pain. About two third (63%) of the respondents were sensitive to weather change; among them 56.3 percent reported that their pain increased during cold weather. Moreover, more than two third (67.4%) study-patients experienced deterioration of pain due to seasonal variation; of them 59.1 percent reported that their pain was exacerbated in winter season. Of all respondents, less than one third (30.4%) experienced aggravation of pain due to lunar change; of them majority (85.7%) experienced increased pain during dark fortnights. Our study concluded that weather change might have an important role in fluctuation of pain among individuals having musculoskeletal disorders.

The mRNAs for acute-phase proteins and kininogens were found to be increased in the submandibular gland (SMG) and extraorbital and intraorbital lacrimal gland (ELG and ILG) in response to experimentally induced inflammation in rats; i.e., 24 hours after subcutaneous injection of turpentine oil, mRNAs for C-reactive protein (CRP), serum amyloid P component (SAP), and H- and T-kininogens were induced in the SMG, ELG, and ILG of rats, whereas these mRNAs were not detected in the same tissues of normal control rats. The induction of mRNAs for these inflammatory proteins by turpentine oil was preceded by a transient increase in the level of mRNA for tumor necrosis factor-alpha (TNF-alpha) at 6 hours after subcutaneous injection of the oil. This was confirmed by injection of another inflammation inducer, lipopolysaccharide (LPS), which induced the TNF-alpha mRNA in the same way at 6 hours as turpentine oil did. The up-regulation of acute-phase proteins including kininogens in the SMG, ELG, and ILG suggest the existence of a strict defense system in the exocrine glands.

We have assessed the effectiveness of using an osmotic sachet for safe rehydration of therapeutic milk from contaminated water supplies in a poor urban area of Bangladesh. 35 women were given sachets to hydrate in their homes and comparison of the hydration water and the reconstituted milk showed that the high bacterial contamination reported in the domestic water supply was removed by use of the sachet. The mean rehydration time was 4.5 h (range 3.4-5.5). This rehydration method could have a role in the preparation of therapeutic feeds where microbiological contamination of the environment is a serious problem and availability of adequate water is not a limiting factor.
