Abstract
INTRODUCTION Organ donation rate in Malaysia is amongst the lowest in the World. Healthcare professionals (HCPs) working in critical care areas play an important role in the deceased organ donation (DOD) process. This study seeks to identify the demographics of HCPs working in the critical care areas and their knowledge and attitudes toward the DOD process. METHOD A cross-sectional survey on the demographics, knowledge and attitudes of the doctors and nurses working in critical care areas was undertaken by the random sampling method, using a validated, structured questionnaire. HCP's knowledge and attitudes towards brain death (BD), DOD, organ transplantation (OT), and possession of organ donor card were compared against their demographics. RESULTS Four hundred and twelve (72.9%) out of the total 565 HCPs in critical care areas responded of whom 163 (39.6%) were doctors and 249 (60.4%) were nurses. After adjusting for other factors, department of work and profession were highly correlated with the overall knowledge score (p<0.001 and p=0.003 respectively) and knowledge about BD (p<0.001 and p=0.013 respectively). HCPs from the neurosurgical intensive care unit (p<0.001) and doctors (p<0.001) had higher mean knowledge scores compared to their counterparts. Profession was most significantly correlated with having a positive attitude towards BD (p<0.001) and OT (p<0.001). CONCLUSION Department, profession and ethnicity were the demographic characteristics that correlated with knowledge and attitudes of HCPs on organ donation. Efforts to improve DOD rates in Malaysia should include targeted interventions to address the knowledge and attitudes of HCPs working in critical care areas.

Abstract
Palonosetron is a new, potent and long-acting 5HT3-receptorsantagonist that had been approved by the FDA for use in postoperative nausea and vomiting (PONV) prophylaxis. The objective of this study was to investigate and compare the prophylactic effects of intravenously administered palonosetron, ondansetron and granisetron on prevention of postoperative nausea and vomiting after general anesthesia. This randomized double blind prospective clinical study was carried out in the Department of Anaesthesia, DMCH, Dhaka, Bangladesh from January 2014 to December 2015. A total of 102 patients who underwent laparoscopic cholecystectomy under general anesthesia, out of which patients who received Palonosetron were in Group A (n=34), patients who received Ondansetron were in group B (n=34) and patients who received Granisetron were in group C (n=34) and also the patients were selected randomly by lottery method. Statistical analyses of the results were obtained by using window based computer software devised with Statistical Packages for Social Sciences (SPSS-22). Nausea was found 3(8.8%) in group A, 8(23.5%) in group B and 6(17.6%) in group C. Vomiting was found 3(8.8%) in group A, 10(29.4%) in group B and 7(20.6%) in group C. Vomiting was significantly higher in group B compare with group A. For group B rescue anti-emetic injection motilon (metoclopramide hydrochloride) 5mg IV slowly was given. Palonosetron is effective prophylaxis against post operative nausea and vomiting.

Abstract
In this paper, the implementations of two reinforcement learnings namely, Q learning and deep Q network (DQN) on the Gazebo model of a self balancing robot have been discussed. The goal of the experiments is to make the robot model learn the best actions for staying balanced in an environment. The more time it can remain within a specified limit, the more reward it accumulates and hence more balanced it is. We did various tests with many hyperparameters and demonstrated the performance curves.

Abstract
End-of-life (EOL) ships contribute significantly to the flow of recycled industrial Fe and non-Fe metal materials in resource-poor developing countries. The ship scrapping (breaking) and recycling industry (SBRI) recycles 90-95% of the total weight of EOL ships and is currently concentrated in Bangladesh, India, Pakistan, Turkey, and China, due to the high demand for recyclable and reusable materials there, an abundance of low-cost labor, and lenient environmental regulations. However, the SBRI has long been criticized for non-compliance with standards relating to occupational health, labor safety, and to the management of hazardous materials. Among the different EOL recycling options, Bangladesh, India, and Pakistan use open beaching, a technique that exposes all spheres of the environment to the release of hazardous materials from EOL ships. This article summarizes the current state of knowledge on the environmental exposure of hazardous materials from SBRI, to judge the risks associated with the dismantling of EOL ships on open beaches. Our work includes an overview of the industry and its recent growth, compares available ship-breaking methods, provides an inventory of hazardous releases from EOL ships, and reviews their movement into different spheres of the environment. The economic dynamics behind open beaching, and apportionment of responsibility for hazards related to it, are discussed, in order to generate policy and legal recommendations to mitigate the environmental harm stemming from this industry.

Abstract
AIMS The aim of this study was to evaluate the antagonistic activity of halotolerant bacteria against rice brown stripe pathogen Acidovorax oryzae. METHODS AND RESULTS Fifteen of 136 isolates of halotolerant bacteria exhibited strong in vitro and in vivo antagonistic activity against both strains of A. oryzae. The 15 antagonistic isolates were identified as 'operational group Bacillus amyloliquefaciens' based on physiological and biochemical features, fatty acid profiles as well as sequence analysis of 16S rRNA, gyrA and rpoB genes. Furthermore, this result indicated that the most effective antagonistic isolates K5-3 and PPB6 could produce siderophore in iron-limiting medium, and four kinds of secondary metabolites based on MALDI-TOF analysis. In addition, the culture filtrates of isolates K5-3 and PPB6 caused the damage of cell membrane evidenced by the TEM images, and resulted in 73-80% reduction in cell numbers, 55-65% reduction in biofilm formation, and 42-50% reduction in swimming ability of both strains of A. oryzae. CONCLUSIONS These isolates in particular K5-3 and PPB6 of halotolerant bacteria markedly inhibited the growth of A. oryzae. SIGNIFICANCE AND IMPACT OF THE STUDY To our knowledge, this is the first report on biological control of halotolerant bacteria against bacterial brown stripe of rice.

Abstract
Two experiments were conducted to determine the effect of replacing soybean meal (SBM) with a high-protein sunflower meal (HiSFM) without or with multi-enzyme mixtures on growth performance, nutrient utilization, jejunal digesta viscosity, and excreta moisture in broiler chickens. In experiment 1, 400 chicks were divided into 40 replicates of 10 birds and fed for 35 d a corn-soybean meal (CSBM) control diet or CSBM with 25 (HiSFM25), 50 (HiSFM50), 75 (HiSFM75), or 100% (HiSFM100) of total SBM replaced by HiSFM. During d 0 to 35, increasing HiSFM content in diets linearly reduced (P < 0.0001) BW, FI, and BW gain (BWG). Feeding HiSFM25 or HiSFM50 resulted in similar growth performance as CSBM (P > 0.05). In experiment 2, 120 chicks were divided into 24 replicates of 5 birds and fed CSBM or HiSFM75 diet without or with enzyme A (supplying 4,000, 500, and 8,000 U/kg of xylanase, alpha-amylase, and protease, respectively) or enzyme B (supplying 1,700, 1,100, 240, 30, 1,200, 360, 1,500, and 120 U/kg of cellulase, pectinase, mannanase, galactanase, xylanase, glucanase, amylase, and protease, respectively) for 21 days. Excreta moisture content was determined weekly, and birds were euthanized on d 22 to collect jejunal and ileal digesta for viscosity and apparent ileal digestibility (AID) measurements, respectively. Compared with CSBM, feeding HiSFM75 reduced (P < 0.05) BWG and G: F, enzymes A and D alleviated BWG and G: F reduction (P < 0.05), and enzyme A reduced (P = 0.037) the excreta moisture content, whereas the treatments did not influence AID or jejunal digesta viscosity measurements. In conclusion, experiment 1 results show that HiSFM can replace up to 50% of SBM without depressing growth performance in either the starter or finisher phase, whereas experiment 2 shows that enzymes A and B supplementation can alleviate the growth depression associated with feeding HiSFM75. These results suggest that enzyme supplementation can enhance HiSFM inclusion in broiler diets without affecting productivity or barn hygiene management.

Abstract
Zinc (Zn) is an essential micronutrient for the growth and development of plants. However, Zn deficiency is a common abiotic stress causing yield loss in crop plants. This study elucidates the mechanisms of Zn deficiency tolerance in maize through physiological and molecular techniques. Maize lines tolerant (PAC) and sensitive (DAC) to Zn deficiency were examined physiologically and by atomic absorption spectrometry (AAS). Proteins, H2 O2 , SOD, POD, membrane permeability and gene expression (using real-time PCR) of roots and shoots of both maize lines were assessed. Zn deficiency had no significant effect on root parameters compared with control plants in PAC and DAC but showed a substantial reduction in shoot parameters in DAC. AAS showed a significant decrease in Zn concentrations in both roots and shoots of DAC but not PAC under Zn deficiency, implying that Zn deficiency tolerance mechanisms exist in PAC. Consistently, total protein and membrane permeability were significantly reduced in DAC but not PAC in both roots and shoots under Zn deficiency in comparison with Zn-sufficient plants. Real-time PCR showed that expression of ZmZIP1, ZmZIP4 and ZmIRT1 transporter genes significantly increased in roots of PAC, but not in DAC due to Zn deficiency compared with controls. The H2 O2 concentration dramatically increased in roots of DAC but not PAC. Moreover, tolerant PAC showed a significant increase in POD and SOD activity due to Zn deficiency, suggesting that POD- and SOD-mediated antioxidant defence might provide tolerance, at least in part, under Zn deficiency in PAC. This study provides an essential background for improving Zn biofortification of maize.

Abstract
The umbilical cord and placental have been considered to significantly contribute to the perinatal outcome. Long or short cord can lead to intrauterine fetal demise. So this type of study in placenta and umbilical cord can yield information for immediate and later management of newborn. This information may also be essential for protecting the attending physician in the event of a fetal outcome. This Cross sectional descriptive study would provide information about the length of umbilical cord in different gestational age groups in Bangladesh. To fulfill this aim the study was performed on 60 human placentas and umbilical cords and Gestational age (in weeks) categorized as Group A (28-32), Group B (33-37), and Group C 38 weeks and above. These samples were collected from normal pregnancy in Gynecology and Obstetrics Department of Mymensingh Medical College Hospital from July 2009 to June 2010. After preservation in 10% normal saline, study was done in the department of Anatomy of Mymensingh Medical College. In this present study the mean±SD length of umbilical cord was found in different gestational age groups in Group A 63.00±5.40, Group B 63.69±8.80 and Group C 67.03±10.64cm and also observed that the mean length of umbilical cord increased with gestational age. The mean length of umbilical cord was maximum in Group C (67.03cm) and was minimum in Group A (63.00cm). The mean difference of length of umbilical cord among different groups was statistically not significant. Observed findings of this study were compared with those of western and Bangladeshi researches.

Abstract
Abstract
Background: The miR-17-92 is an oncogenic miRNA cluster that generate six mature miRNAs: miR-17, miR-18a, miR-19a, miR-20a, miR-19b-1, and miR-92-1. Accumulating evidences indicate the oncogenic role of the miR-17-92 cluster in human cancers. Amplification of 13q31-q32, which is the locus of the miR-17-92 cluster, have been reported in haematopoietic malignancies, such as B cell lymphoma. In contrast, MIR17HG was deleted in 21.9% of breast cancers and loss of heterozygosity at 13q12-q13 was associated with poor prognosis in breast cancer. This oncogenic miRNA cluster is deferentially expressed in various cancer. Since, miR-17-92 cluster shows differential expression among the cancers types, it is hypothesized that biological function may also vary depending on the context. Indeed, this cluster has been shown to act a tumour suppressor in some cancers. However, the functional role of this cluster in the subtypes of breast cancer remains largely unknown.
Methods: The oncomine datasets were analysed for expression of MIR17HG in breast cancer at parameters p-value threshold of 0.01 with minimum 2-fold change. We generated stable sub-clones of MCF7, T47D, SKBR3 and MDA-MB231 cells overexpressing miR-17-92 cluster by transducing with lentivirus expressing miR-17-92. Proliferation was assessed by MTS assay and colony forming assay. Cell migration was tested using scratch method. Invasion potentiality was monitored by using matrigel Boyden chamber invasion assay. For drug response analysis, control and microRNA overexpressing sub-clones were exposed to different chemotherapeutic agents at different concentrations followed by MTS assay at different time intervals. Association of miRNAs belonging to miR-17-92 with outcome in breast cancer was determined by Kaplan-Meier analysis on METABRIC dataset.
Results: We observed that expression of MIR17HG was increased in tissues and cell lines from triple negative breast cancer (TNBC) but decreased in the tissues and cell lines from the estrogen receptor (ER)-positive breast cancer. Our results showed that ectopic expression of miR-17-92 cluster significantly suppressed cell proliferation, colony formation, migration and invasion of ER-positive (MCF7, T47D) and HER2-enriched (SKBR3) cells whereas it enhanced cell proliferation, colony formation, migration and invasion in (TNBC) MDA-MB 231 cells. Further, we found that expression of miR-17-92 cluster sensitized MCF7 cells whereas it rendered SKBR3 cells resistant to chemotherapeutic compounds. Higher expression of five miRNAs of this cluster was associated with better relapse free survival (RFS) in (miR-17, miR-19a, miR-20a, miR-19b and miR-92) Luminal A subtype whereas three miRNAs of this cluster were associated with poor RFS in (miR-17, miR-18a and miR-92) HER2-enriched and (miR-17, miR-19b and miR-92) TNBC subtypes.
Conclusions: Taken together our results suggest that miR-17-92 cluster acts as a tumour suppressor in ER-positive and HER2-enriched breast cancer cells but shows oncogenic role in TNBC. Our observations underscore the functional complexity of miR-17-92 in a context-dependent and cell type-dependent manner, and more investigations are warranted to fully explore the functional complexity of miR-17-92 in subtypes of breast cancer.

Abstract
Here we present a Bangladeshi family where out of four family members two (mother and son) inherited both haemoglobin (HbS) S and haemoglobin (HbE) E gene confirming the diagnosis of double heterozygous state for HbS and HbE, presented in the Armed Forces Institute of Pathology (AFIP), Dhaka Cantonment, Dhaka, Bangladesh on the month of July 2016. Among other two members, one (daughter) inherited HbS and other (father) HbE. Double heterozygous state for HbS and HbE is a rare condition in this subcontinent especially in Bangladesh. HbS is rare but HbE is prevalent in Bangladesh. Co-inheritance of both HbS and HbE is therefore uncommon in this country in comparison to HbE/β - thalassaemia. Though the double heterozygous state for HbS and HbE is rare and the patients are usually asymptomatic but their documentation is important for genetic counseling and to determine the reproductive risk of the family.

Abstract
To study the effects of diet complexity and multicarbohydrase (MC) supplementation, 144 piglets (6.70 ± 0.81 kg of BW) weaned at 21 ± 2 d of age (1:1 male to female ratio) were assigned to 1 of 6 dietary treatments in a 3 × 2 factorial arrangement based on diet complexity (complex1, complex2, and simple) and MC addition (0 vs. 0.1% of MC). Diets were provided in a 2-phase feeding program with phase I (d 1 to 14) and phase II diets (d 15 to 28). Complex1 was formulated to mimic a conventional weaner diet with blood plasma, fish meal, dried whey, and skim milk powder, whereas complex2 partially or totally replaced these ingredients with various plant-based ingredients. The simple diet primarily comprised corn, wheat, and soybean meal. No interactions were found between diet complexity and MC supplementation ( > 0.10), except for apparent total tract digestibility (ATTD) of ash and globulin concentration on d 28 ( < 0.05). Pigs fed the complex1 diet had greater ( < 0.01) ADG, ADFI, and G:F than those fed the other diets during the first week after weaning. However, no differences in ADG or ADFI were observed for pigs fed the complex1 and simple diets throughout the 28-d experimental period ( > 0.10), whereas the complex2 diet led to lower ADG and ADFI compared with the complex1 diet ( < 0.05). Overall, G:F was greater for pigs fed the simple diet compared with those fed the complex1 diet ( < 0.01). Pigs fed the simple diet showed ATTD of DM, OM, GE, and ash comparable to those fed the complex1 diet on d 14 ( > 0.10). In contrast, greater ATTD of DM, OM, NDF, GE, and ash was observed ( < 0.05) in pigs fed the complex1 diet than in those fed the complex2 diet or the simple diet on d 28. The simple diet increased the lymphocyte proportion in serum compared with the complex1 diet ( < 0.01) on d 14. Pigs fed the complex1 diet had a greater ( < 0.05) ratio of villus height (VH) to crypt depth (CD) in the ileum compared with the other diets. The complex2 diet decreased ( < 0.05) the fecal score during 3 wk of the postweaning period compared with the complex1 diet. Dietary MC supplementation increased ( < 0.05) G:F during the overall experimental period, VH in the ileum, VH:CD ratio in the duodenum, and ATTD of DM and GE but it reduced fecal score ( < 0.05). In conclusion, feeding a simple diet resulted in BW comparable to feeding the complex1 diet, but it led to inferior intestinal morphology and ATTD of nutrients on d 28. Also, MC supplementation could be beneficial regardless of diet complexity.

Abstract
Determination of age is one of the most important and vital demand in legal affairs, court and young sports, especially from 7-21 years. There is no established age determination table in our county. So we are dependent upon Galstaun, Bashu & Bashu and other European tables, which sometimes provide misinterpretation and variation of opinion. We should have our own table suitable for our nation. So, this prospective study was carried out in the Department of Radiology and Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2010 to June 2014 (five years) to assess the general skeletal maturity. Three hundred boys and girls of known date of birth were selected on random basis from Dhaka. Ages were limited within 7 to 21 year. Every 20 person for each age group, of them 10 were male and 10 were female. To observe the bony maturity, radiographs were taken at the end of their age belongs to. Thus a growth table is to be prepared for further evaluation.

Abstract
Post operative complications after pituitary tumour surgery vary according to procedure. There are several surgical procedures being done such as transcranial, transsphenoidal microsurgical and transsphenoidal endoscopic approaches. One of the commonest complications is diabetes insipidus (DI). Our main objective was to find out the incidence of diabetes insipidus in post operative period among patients undergoing surgical intervention for pituitary tumour in our institute. The presence of diabetes insipidus in the postoperative period was established by measuring serum Na+ concentration, hourly urine output and urinary specific gravity to find out the incidence of diabetes insipidus in postoperative period in relation to age, gender, tumour diameter, function of tumour (i.e., either hormone secreting or not) and operative procedure used for surgical resection of pituitary tumor. As it is the most common postoperative complication so, in this study we tried to find out how many of the patients develop diabetes insipidus in postoperative period following surgical resection of pituitary tumour. This cross sectional type of observational study was carried out in the department of Neurosurgery, BSMMU from May 2014 to October 2015 on 33 consecutive patients who underwent surgical intervention for pituitary tumour for the first time. Data was collected by using a data collection sheet. The incidence of diabetes insipidus was found 23.1% of patients in <30 year age group, 38.5% of patients in 31-40 year age group and 38.5% of patients in ≥40 year age group (p=0.764). In case of distribution of patients according to gender 38.5% of male and 61.5% of female developed diabetes insipidus (p=0.073). Regarding tumour size 30.8% and 69.2% of patients developed diabetes insipidus having tumour diameter <30mm and ≥30mm respectively (p=0.590). In case of operative procedure 69.2% of patients developed diabetes insipidus who was operated by transsphenoidal endoscopic approach, 23.1% and 7.7% of patients developed diabetes insipidus who underwent pituitary tumour resection through transsphenoidal microscopic approach and transcranial microscopic approach respectively (p=0.432). 17.6% of patients develop DI having functioning pituitary macroadenoma and 62.5% of patients develop DI having nonfunctioning pituitary macroadenoma. This observational study has been performed to find out the incidence of diabetes insipidus. Incidence of postoperative DI is more at or around the age of 40 years. It is slightly predominant in female. Most of the patients manifest DI in the first 24 hours of surgical intervention. Incidence of DI is low among patients having functioning pituitary macroadenoma.

Abstract
Breast cancer is the most common malignancy in women and the second most common cause of cancer-related mortality. The distinction by physical examination of physiologic nodularity from abnormal masses can be difficult, while the clinical differentiation of a malignant mass from a benign one is difficult; the medical as well as potential legal consequences of missing a palpable carcinoma are high. There are significant number of reported cases of false-negative findings on mammography and the great desire not to miss a malignant lesion in the early stage of disease lead to aggressive biopsy, but the biopsy rate for cancer is only 10.0% to 30.0%. This means that 70.0% to 90.0% of breast biopsies are performed for benign diseases, which induce unnecessary patients discomfort and anxiety in addition to increasing costs to the patient. Clearly, there is a great need for development of additional reliable methods to complement the existing diagnostic procedures to avoid unnecessary biopsy. This cross sectional study was carried out on 43 patients having palpable breast mass, attended in the Department of Radiology and Imaging Mymensingh Medical College Hospital, Mymensingh from 1st January 2012 to 31st December 2013 for the period of two year. These patients were evaluated by USG at the Department of Radiology and Imaging and histopathological examination at the Department of Pathology of the same College to confirm the diagnosis. In diagnosis of malignant mass by USG, 9(20.9%) cases were diagnosed as malignant and 34(79.1%) cases as other than malignant. Eight out of 9 were sonographically diagnosed as malignant lesions also proved as malignant lesion by histopathology and 1 other than malignant. Out of 34 sonographically diagnosed cases of other than malignant lesions 32 were proved histopathologically and 2 did not match with sonographic findings. USG, in diagnosis of malignant lesion, sensitivity was 80.0%, specificity 96.97%, positive predictive value (PPV) (88.89%), negative predictive value 94.12% and accuracy was 93.02% and comparable to other study. In diagnosis of benign lesion by USG, sensitivity was 96.97%, specificity 80.0%, positive predictive value (PPV) (94.12%), negative predictive value 88.89% and accuracy was 93.02%. So, USG is an appropriate imaging method for diagnosis & differential diagnosis of palpable breast mass.

Abstract
Currently there is no effective approach for monitoring early β-cell loss during islet graft rejection following human islet transplantation (HIT). Due to ethical and technical constraints, it is difficult to directly study biomarkers of islet destruction in humans. Here, we established a humanized mouse model with induced human β-cell death using adoptive lymphocyte transfer (ALT). Human islet grafts of ALT-treated mice had perigraft lymphocyte infiltration, fewer insulin+ β cells, and increased β-cell apoptosis. Islet-specific miR-375 was used to validate our model, and expression of miR-375 was significantly decreased in the grafts and increased in the circulation of ALT-treated mice before hyperglycemia. A NanoString expression assay was further used to profile 800 human miRNAs in the human islet grafts, and the results were validated using quantitative real-time polymerase chain reaction. We found that miR-4454 and miR-199a-5p were decreased in the human islet grafts following ALT and increased in the circulation prior to hyperglycemia. These data demonstrate that our in vivo model of induced human β-cell destruction is a robust method for identifying and characterizing circulating biomarkers, and suggest that miR-4454 and miR-199a-5p can serve as novel biomarkers associated with early human β-cell loss following HIT.

Abstract
To evaluate the biochemical parameters of metabolic syndrome in case of acute myocardial infarction (AMI) patients this case control study was carried out in the department of Biochemistry, Mymensingh Medical College in collaboration with Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2012 to June 2013. To assess of serum total cholesterol, triacylglycerol, HDL-cholesterol, LDL-cholesterol, to estimate of serum glucose and to establish the association of age, sex, BMI, waist circumference, waist hip ratio and blood pressure of myocardial infarction patients. A total of 120 subjects were included in the study. Among them 60 were subjects of AMI cases and another 60 subjects of non AMI patients as controls. Serum total cholesterol, serum triacylglycerol, serum LDL-Cholesterol & serum HDL-Cholesterol were estimated in each sample. All values were expressed as Mean±SD. Statistical significance of difference between case and control were evaluated by using student's unpaired 't' test. All statistical analysis was done by using SPSS windows package. Past history of diabetes Mellitus and hypertension were more common in cases compared to those in control (p<0.001) which was statistically highly significant. There was no significant difference in the history of smoking between case and control. Statistical mean values of serum triacylglycerol, serum FBS, serum total cholesterol were highly significant in AMI patients in comparison to control (p<0.001). Statistical mean value of HDL-C was significantly decreased in AMI patients in contrast to control (p<0.001). In this study systolic blood pressure and diastolic blood pressure were significantly increased in AMI patients in comparison to control (p<0.05). Waist circumference was highly significant in AMI patients in comparison to control (p<0.001). Analyzing the findings of the present study there were significant alteration in lipid profile, blood pressure, fasting blood sugar & WC. These findings reaffirm the clinical importance of the metabolic syndrome as a significant risk factor for AMI. So it may be recommended that estimation of these parameters may help pivotal for better management of AMI.

Abstract
AIMS The present study aims to study the prevalence of depression in patients with uncomplicated type II diabetes mellitus and to find its association with various socio-demographic factors in the same. MATERIALS AND METHODS A cross-sectional, single interview study was performed in an outpatient department of an endocrinology institute. Total 80 type II DM patients without any associated complications of diabetes were included in this study. To diagnose Depressive Episode, structured clinical interview for DSM V was applied. Severity of depression was assessed by Hamilton Rating Scale for Depression (HAM-D). To assess socio-demographic characteristics of the patients, all of them were evaluated with a semi-structured socio-demographic performa. RESULTS 38.75% patients (N=31) were found to be suffering from depression. Among them 48.38% were moderately depressed and none were suffering from very severe depression. Significant association was not found between depression and socio-demographic factors of age (p=0.920), gender (p=0.251), economic profile (p=0.583), local background of the patient (p=0.646), educational qualification (p=0.935) and marital status (p=0.644). Similarly no association was found with duration of diabetes, HbA1c and BMI. CONCLUSION Exclusion of complicated cases didn't seem to influence overall prevalence of depression, although reduction in severity was apparent. Thus even in those diabetic patients who are leading a complication free life, a detailed psychiatric analysis to rule out depression is mandatory.
