Abstract
Hypertension is a common disorder of major clinical, public health and economic importance. It affects men and women of all ages, and the prevalence is increasing in most countries. Maintenance of blood pressure below 140/90 mm of Hg is recommended by most of the guideline available around the world. Various classes of drugs are being used in the treatment of hypertension. Losartan potassium and amlodipine are two different antihypertensive agents belonging to two different groups used commonly around the world in treating essential hypertension. Losartan potassium is non-peptide Angiotensin-II receptor antagonist. Amlodipine which is the third generation dihydropyridine group of calcium channel blocker. The aim of the study was to compare the efficacy and safety of amlodipine and losartan for the treatment of essential hypertensive patients (18-75 years). A non-randomized comparative observational study was conducted in the Department of Pharmacology and Therapeutics in collaboration with Department of Medicine, Sylhet, MAG Osmani Medical College, Sylhet, Bangladesh from July 2021 to June 2022. In this study non-randomization was in two groups. Group A received amlodipine 5mg daily at morning and Group B received losartan potassium 50mg daily at night. The study parameters were systolic blood pressure (SBP), diastolic blood pressure (DBP), ankle oedema, serum K+ level. The result of treatment outcome was compared between two groups. After treatment the reduction of SBP was 5.19±2.93mm of Hg versus 3.27±1.34mm of Hg (p<0.001); reduction of DBP was 1.7±0.70 mm of Hg versus 0.68 mm of Hg (p<0.001) and serum K+ level 4.22±0.27mmol/L versus 4.21±0.16mmol/L (p<0.719) in amlodipine and losartan group respectively. Amlodipine is more effective than losartan potassium in respect to treatment of essential hypertension. Regarding adverse events losartan potassium causes angioedema, hyperkalemia, headache, dizziness etc. The study concluded that amlodipine is superior to losartan potassium in treating essential hypertension.

Abstract
Evaluation of the in vitro antibacterial activity of Methanolic extracts isolated from Black pepper seeds (Piper nigrum L.) against two infection causing pathogens, Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. Between July 2022 and June 2023, this experimental study was conducted at the Mymensingh Medical College's Department of Pharmacology and Therapeutics in conjunction with the Department of Microbiology. Using the disc diffusion and broth dilution methods, the antibacterial activity of methanolic extract of black pepper seeds (MBPE) was evaluated at various doses. The solvents Methanol and 10.0% Di Methyl Sulfoxide (DMSO) were used to make the extract. Using the broth dilution procedure, the conventional antibiotic Ciprofloxacin was utilized and the outcome was contrasted with that of Methanol extracts. Methanolic extract of black pepper seeds (MBPE) at seven distinct concentrations (100, 80, 60, 40, 20, 10 and 5 mg/ml) were utilized, then later in chosen concentrations as needed to confirm the extracts' more precise margin of antimicrobial sensitivity. At 80 mg/ml and above doses of the MBPE, it had an inhibitory impact against the aforementioned microorganisms. For Staphylococcus aureus and Escherichia coli the MIC were 60 and 75 mg/ml in MBPE respectively. As of the MIC of Ciprofloxacin was 1μg/ml against Staphylococcus aureus and Escherichia coli. In comparison to MICs of MBPE for the test organisms, the MIC of Ciprofloxacin was the lowest. This study clearly shows that Staphylococcus aureus and Escherichia coli are sensitive to the methanolic extract of black pepper seeds' antibacterial properties.

Abstract
Globally, the emergence of multidrug-resistant strains of Mycobacterium tuberculosis is an increasing problem that adversely affects patient care and public health. This cross sectional descriptive study was carried out in the Department of Microbiology, Mymensingh Medical College from January 2010 to December 2010 to isolate M. tuberculosis from smear-positive sputum samples by Lowenstein-Jensen (L-J) media and investigate the drug resistance pattern. Among 101 smear-positive cases 80(79.20%) yielded growth of Mycobacteria, 5(4.95%) were contaminated and 16(15.84%) showed no growth. Among 80 isolates 76(95.0%) were M. tuberculosis and the remaining 4(5.0%) were Non-tuberculous Mycobacteria (NTM). Out of 76 M. tuberculosis 27(35.52%) were resistant to at least one drug, 4(5.26%) to Isoniazid (INH), 1(1.32%) to Rifampicin (RMP), 8(10.53%) to Streptomycin (SM) and 0(0.0%) to Ethambutol (EMB) and multi-drug resistant tuberculosis (MDR-TB) was 9(11.84%). The present study creates the impression that fairly high rate of anti-tuberculosis drug resistance among the tuberculosis cases and also high MDR-TB (Resistant to both Rifampicin and Isoniazide). The emergence of MDR-TB poses significant trouble to TB control activities throughout the world. The complexity of MDR-TB operation makes it essential to produce new skills to design, plan, application and monitor interventions for the management of MDR-TB. More surveillance and immediate remedial interventions should be performed to combat the trouble of MDR-TB to the general population.

Abstract
Burn injury causes a lot of suffering. The goal of burn management is to achieve rapid wound healing, pain relief, rehabilitation with minimum scars and optimal functional ability. Objective of this study was to compare the efficacy of collagen sheets and 1% silver sulfadiazine dressing (SSD) for superficial partial thickness burns. This prospective observational study was conducted among the patients of Department of Plastic surgery, Dhaka Medical College Hospital, and Sheikh Hasina National Institute of Burn and Plastic Surgery, Dhaka, from 1st April 2020 to 31st March 2021. Total 60 patients with superficial partial thickness burns by purposive sampling 30 patients of them were treated with collagen sheet dressing (Group A) and 30 patients with 1.0% silver sulfadiazine dressing (Group B). First case was selected by tossing a coin. Then every alternate patient was provided the same kind of dressing material (either collagen sheet or 1.0% silver sulfadiazine). Data were collected by semi structured data collection sheets. Pearson's chi-square test and student's 't' test were used for data analysis (p value was significant at <0.05). It was observed that a total of 18(60.0%) patients belonged to age <10 years in Group A and 17(56.7%) patients in Group B. The mean age was 14.9±14.2 years in Group A and 11.6±10.2 years in Group B. Good quality of healing was significantly higher in the collagen group compared to the SSD group (<0.05). The mean complete healing time in the collagen group was 10.47±2.21 days and in the 1.0% SSD group were 13.07±2.33 days. The mean healing time was significantly lower in the collagen group compared to the 1.0% SSD group (p<0.001). There was no significant difference in infection rate between the two groups (p>0.05). Considering the overall outcome, Collagen sheet dressing decreases pain, reduces the need for analgesics, aids in early healing as compared to the patients treated with 1% silver sulfadiazine.

Abstract
Severe acute malnutrition (SAM) is the most severe form of protein energy malnutrition (PEM). Few studies found serum electrolyte, serum calcium level changes as important factors of poor outcome. Hypoglycemia is already established as a risk factor for death in severe acute malnutrition. Edema, diarrhea and vomiting are commonly present in severe acute malnutrition which has impact on electrolyte balance and blood sugar level in healthy children. Their impact in severe acute malnutrition is not clearly established. This cross sectional descriptive study was conducted in Department of Pediatrics, MMCH from March 2018 to October 2019 to estimate serum electrolyte, serum calcium and random blood sugar level in severe acute malnutrition and their relationship with edema, vomiting and diarrhea. Forty-one (41) cases of SAM were enrolled in this study. Test samples were collected before starting the treatment. Case record form was used to collect information. Cases were divided into Group A and Group B based on the presence or absence of vomiting or diarrhea, respectively. Again, all cases were divided into Group C and Group D based on presence or absence of edema, respectively. Data were analyzed using IBM SPSS statistics version 23. Mean age was 9.71±10.4 months with 85.36% having age less than 1 year. Twenty-four (58.5%) were male and 17(41.5%) were female. Parents had low level of education with 48.8% mother and 51.2% father having primary education or no education. Higher number of serum electrolyte, serum calcium and blood sugar were found with hyperglycemia present in 29.3%, hypocalcemia in 22%, hypokalemia in 22% and hyponatremia in 19.5% cases. Hypokalemia was present more in SAM with vomiting or diarrhea (p=0.008). Other disturbances do not vary on presence or absence of edema and vomiting or diarrhea. Result of the present study shows hypokalemia is associated with SAM with vomiting/diarrhea. Hypocalcemia, hyperglycemia, hyponatremia and hypernatremia were also present in high number. These changes should be detected early and treated accordingly.

Abstract
Antimicrobial resistance mediated by extended-spectrum beta-lactamases (ESBL), AmpC beta-lactamase and metallo-beta-lactamase (MBL) producing Acinetobacter species is an emerging problem worldwide. In this cross-sectional study total 341 specimens were collected over a period of one year from January 2017 to January 2018. Specimens were collected from ICU and Surgery unit of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Specimens were collected from ICU and Surgery Unit of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Samples were processed for culture by standard conventional methods and susceptibility testing and determined by Kirby Bauer disc diffusion method. Antibiotic discs and their strength were according to the CLSI 2017 guideline. Molecular study was done to detect the species by OXA-51 gene and drug resistance genes (IMP, VIM, NDM, TEM, SHV, CTX, SPM, SIM and GIM). Species identification was done by OXA-51 gene which is intrinsic to Acinetobacter baumannii. Among the 46 isolates, 36(78.26%) were positive for Oxa-51 gene, 16(34.8%) for TEM gene, 9(19.6%) for VIM gene, 3(6.5%) for NDM gene and 1(2.2%) for IMP gene. This study gives an alarming sign towards high prevalence of cephalosporin and carbapenem resistance due to production of extended spectrum beta-lactamases and metallo-betalactamases, respectively. Early detection, proper antibiotic policies, and compliance towards infection control practices are the best defenses against these organisms.

Abstract
There is progressive increase of Hb levels is observed during course of intrauterine development of fetus but high concentrations found at birth. In preterm neonate normal Hb is characteristically deviated from term neonate. Breast milk is the only natural ideal food for both term and preterm babies from birth up to 6 months. Preterm milk was found to contain significantly higher concentrations nutrients particularly iron than term milk. Preterm human milk is more suitable for the premature infant than term human milk. As Hb concentration varies in term and preterm babies in different counties in different feeding practices. The purpose of this longitudinal descriptive study is to find out the pattern of changes in the Hb level among exclusively breastfed preterm and term infants during the first six months of life. This study was carried in the Neonatal Intensive Care Unit (NICU), Mymensingh Medical College Hospital (MMCH), Mymensingh from September 2016 to February 2018. One hundred fifty (150) neonates both term and preterm were included in this study and followed up to 6 months of age. After admission informed written consent was taken from parents, thorough history taking and clinical examination were done. Data were collected in a pre-designed case record form. All the babies of Group A provided 2mg/kg iron supplementation from 6 weeks for 2 months for universal recommendation. Hb level was measured of all exclusively breast feed babies at admission after birth then next follow-up at 6 weeks, 3 months and 6 months. All information regarding history, anthropometrics measurement, Hb level was recorded in structural questionnaire. Data analysis was done by SPSS version 20.0. Male were predominant in both groups. Most of the preterm (72.0%) and term babies (65.3%) were delivered by vaginal route. Mean Hb level was found significantly higher among preterm babies than term babies after birth were 16.55g/dl and 15.98g/dl respectively. Sharp fall of Hb concentration was observed after birth up to 6 weeks in both preterm and term babies but Hb level was found significantly lower in preterm in comparison to term babies (9.27gm/dl vs. 9.58gm/dl). In term babies, even after 6 weeks fall of Hb level continued to 3 months of age followed by gradual increase up to 6 months without iron supplementation. Hb level of in preterm babies gradually increased from 6 weeks up to 6 months with universal iron supplementation. Hb level fall sharply up to 6 weeks in both exclusively breastfed term and preterm babies but even after 6 weeks term babies experienced gradual fall of Hb levels up to 3 months. Hb level increases in exclusively breast-fed term babies without iron supplementation from 3 months of age. Hb level in exclusively breastfed preterm babies increase from 6 weeks onward might be effect of universal iron supplementation.

Abstract
Medical education is associated with a great psychological distress that affects many aspects of students' lives, including their academic performance and professional development. The objective of the study was to determine the level of depression, anxiety and stress and their academic performance among fifth year medical students. This was a cross-sectional descriptive study conducted in Dhaka Medical College, Mymensingh Medical College, Anwar Khan Modern Medical College and Community Based Medical College of Bangladesh. For this purpose, 359 students were taken as sample and self-administered semi-structured questionnaire was used to collect data. Depression, anxiety and stress were assessed by using short form DASS-21 BV score. The results showed that, the mean age of students was 22.74 years with female predominance 230(64.0%). Majority 319(88.9%) of the respondents' parents monthly income was ≤100000 taka and one third 126(35.1%) respondents' monthly study expenditure was in between 5001 to 10000 taka. Four fifth 317(88.0%) of the respondents came from nuclear type of family and two third 245(68.2%) lived in hostel. Half 178(50.0%) of the respondents were eldest in birth order. Majority 221(61.6%) of the students were admitted to medical college by their own motivation and interest. Symptoms of depression, anxiety and stress were present in 179(49.9%), 215(59.9%) and 161(44.8%) respectively. No significant association was found between academic performance with depression or anxiety or stress, except class attendance of Gynaecology and Obstetrics which was significantly associated with stress (p=0.016); the students who suffered from more stress, their class attendance were very poor. Students who reappeared in MBBS professional examination were significantly associated with depression (p=0.032) and stress (p=0.036). There was significant difference between students of public and private medical colleges in terms of anxiety (p=0.031) that is students of public medical colleges more suffered from depression, anxiety and stress in comparison to private medical colleges. Depression (p=0.001) and anxiety (p=0.010) were significantly associated with motivation to study MBBS. No significant difference of depression, anxiety or stress was found with sex difference. This study revealed that fifth year MBBS students suffered more from depression, anxiety and stress. The causes of depression, anxiety and stress should be identified and resolved to improve their mental health and academic performance.

Abstract
During last several years, Kuwait Institute for Scientific Research (KISR), Kuwait has been trying to develop a sustainable culture technique for silver pomfret (Pampus argenteus). This paper reports the recent research advances in the breeding and rearing of silver pomfret fry at KISR. The eggs collected from wild silver pomfret during spawning seasons of 2012 to 2015 were artificially fertilized under laboratory condition. The average hatching rates of artificially fertilized eggs collected from wild silver pomfrets were 25.6%, 44.8%, 76.7%, and 53.5.0% and average survival rates of metamorphosed fry produced from these eggs were 3.7%, 5.7%, 4.4% and 3.8% for the spawning seasons 2012, 2013, 2014, and 2015, respectively. For captive brood stocks, observation on the spawning time at hourly interval by collecting eggs from the nets set at out-flow of brood tanks showed that the spawning time for captive silver pomfret starts at the time of sunset. In 2012, two groups of captive silver pomfret broods spawned a total of 62x103 and 66x103 eggs, but the eggs were unfertilized. No captive spawning occurred during 2013 and 2014 spawning season. In 2015, captive silver pomfret broods in three tanks spawned about 653x103, 673x103 and 270x103 eggs, and in 2016, the broods in four tanks spawned about 669x103, 22x103, 3x103 and 366x103 eggs. However, from these eggs only 1,400 and 1,000 fertilized eggs were collected which produced 300 and 123 hatched larvae in July 2015 and June 2016, respectively. The larvae produced from the 2015 broods did not survive beyond 56 days of metamorphosed stage while larvae produced from 2016 captive broods survived for 9 days only. The mortality of the larvae from captive brood could be related to the poor egg or milt quality. However, efforts are continued to improve the eggs and sperm quality through proper brood management.

Abstract
Eosinophilic esophagitis (EoE) is a disease of modern era. It was first described 40 years back. Since then it has drawn an immense interest among the clinicians. It is diagnosed by the presence of eosinophils count ≥15/HPF on esophageal biopsied mucosa in patients with symptoms of esopohageal dysfunction. It is more prevalent among patients with gastroesophageal reflux disease. As its symptoms overlap with that of gastroesophageal reflux disease (GERD), it is frequently overlooked & misdiagnosed which increases patients' sufferings. No data is available in Bangladesh. The objective of the study was to find out the frequency of eosinophilic esophagitis among patients with gastroesophageal reflux symptoms. The study was conducted at the Outpatient department of the department of Gastroenterology of Dhaka Medical College Hospital, Dhaka, Bangladesh from September 2018 to April 2019. One hundred and thirty three (133) consecutive patients with symptoms suggestive of gastroesophageal reflux disease based on validated questionnaire underwent upper GI endoscopy. Biopsies were taken from proximal and distal esophagus as well as any other endoscopically abnormal esophageal mucosal lesion. Among 133 patients with gastroesophageal reflux symptoms, 7 patients (5.3%) were found to be positive for eosinophilic esophagitis. Mean age at diagnosis was 37.28±13.38 years. It was more common in younger age group. Female patients (56%) were more than male patients (44%). Heart burn was the major symptom followed by acid regurgitation. Nocturnal cough showed statistically significant relationship with eosinophilic esophagitis. Although the frequency is low, it may be considered as a differential diagnosis among patients with GERD.

Abstract
Urinary tract infection (UTI) is a common complication in nephrotic children and leads to most morbidity and mortality in developing countries like Bangladesh. This case control study was conducted in the Department of Pediatrics and Pediatric Nephrology ward of Dhaka Medical College Hospital, Dhaka from July 2016 to June 2018 to identify the risk factors of UTI in children with nephrotic syndrome. Total 90 patient of nephrotic children aged 2-12 years, who were fulfilling the inclusion and exclusion criteria were selected as Group I (case) and Group II (control) according to urine culture report. Group I was UTI positive and Group II was UTI negative. The mean age of Group I was 5.26±3.18 years and Group II was 6.03±2.85 years. There was male predominance in both groups. No significant difference has been found regarding age and sex (p>0.05). No significant difference was also observed regarding economic status and educational level of mother among both groups (p>0.05). Fever, dysuria, abdominal pain, anasarca, vomiting and pallor were found as common presentations in Group I. Children with dysuria and abdominal pain were significantly higher in Group I than Group II (p value <0.001). UTI was found more in relapsed cases than initial attack. E. coli was the most common etiologic agent (37.8%). Mean Hb (gm/dl), serum total protein, serum albumin and serum IgG level were found significantly lower and spot urine protein creatinine ratio was significantly higher in Group I, which implies that those biochemical factors were associated with development of UTI in nephrotic children. Younger age group (<6 years), Constipation and uncircumcised male were found as risk factors and has association with UTI in nephrotic children.

Abstract
Copper (Cu) pollution of agricultural land is a major threat to crop production. Exogenous chemical treatment is an easily accessible and rapid approach to remediate metal toxicity, including Cu toxicity in plants. We compared the effects of ascobin (ASC; ascorbic acid:citric acid at 2:1) and glutathione (GSH) in mitigation of Cu toxicity in rice. Plants subjected to Cu stress displayed growth inhibition and biomass reduction, which were connected to reduced levels of chlorophylls, RWC, total phenolic compounds, carotenoids and Mg2+ . Increased accumulation of ROS and malondialdehyde indicated oxidative stress in Cu-stressed plants. However, application of ASC or GSH minimized the inhibitory effects of Cu stress on rice plants by restricting Cu2+ uptake and improving mineral balance, chlorophyll content and RWC. Both ASC and GSH pretreatments reduced levels of ROS and malondialdehyde and improved activities of antioxidant enzymes, suggesting their roles in alleviating oxidative damage. A comparison on the effects of ASC and GSH under Cu stress revealed that ASC was more effective in restricting Cu2+ accumulation (69.5% by ASC and 57.1% by GSH), Ca2+ and Mg2+ homeostasis, protection of photosynthetic pigments and activation of antioxidant defence mechanisms [catalase (110.4%), ascorbate peroxidase (76.5%) and guaiacol peroxidase (39.0%) by ASC, and catalase (58.9%) and ascorbate peroxidase (59.9%) by GSH] in rice than GSH, eventually resulting in better protection of ASC-pretreated plants against Cu stress. In conclusion, although ASC and GSH differed in induction of stress protective mechanisms, both were effective in improving rice performance in response to Cu phytotoxicity.

Abstract
This cross-sectional analytical study was conducted in the department of Paediatrics, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from March 2017 to August 2018 to assess the pattern of serum iron profile and red cell indices in children with severe acute malnutrition. Seventy children having severe acute malnutrition were compared with 70 age matched children those had normal growth. Age range of the studied children was 6 months to 59 completed months. Male was found predominant (54.3%) in both study group and comparison group. Mean serum iron, serum ferritin, serum total iron binding capacity and transferrin saturation in severely malnourished children were 45.3±19.3μg/dl, 26.5±20.0ng/ml, 246.3±47.5μg/dl and 16.4±2.0% respectively which were significantly lower than that of healthy children (p<0.05). Mean Hb level in children with severe acute malnutrition was found 8.3±1.6gm/dl which was also found significantly lower than that of normal children (p<0.05). Anaemia was found in all (100%) severely malnourished children compared to 25.7% of children in comparison group. Mean MCV, MCH and MCHC in children with severe acute malnutrition was found 71.7±13.5fl, 24.0±5.8pg and 31.4±4.0gm/dl respectively which were significantly lower than that of comparison group (p<0.05). Serum iron profile and red cell indices should be routinely done in severely malnourished children for early intervention and management of iron deficiency anaemia.

Abstract
Undernutrition in children under five years remains a significant health problem in Bangladesh, despite substantial socio-economic progress and a decade of interventions aimed at improving it. Although Bangladesh has made rapid progress over the last decade in the field of health and nutrition, there has been very slow progress in improving the state of child nutrition. Studies aiming at determination of interrelationship between child undernutrition and maternal undernutrition are to be scientifically established if appropriate intervention policy is to be introduced. This study was undertaken to see whether this assumption has a statistically proven basis that maternal undernutrition influences child undernutrition. The objective of this cross sectional analytical study was to evaluate the association between child undernutrition and their maternal undernutrition in child-mother pair in a tertiary care hospital and was conducted from July 2017 to April 2018 in the department of General Paediatrics, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. The study subjects were 196 children between the ages of six months to five years who were admitted in BSMMU and their accompanying mothers. Children who had any known chronic diseases or clinically obvious syndrome were excluded. Before enrollment, parents of all the patients were informed about the study & its objectives. Anthropometric measurements of children and mothers were done by standard procedure. Demographic profile and relevant maternal information were collected by interviewing the mothers. Among the undernourished children, 17.3% were found underweight, 7.1% stunted, 16.3% wasted. Combined underweight & wasted were 34.7%, underweight & stunted 9.2%, stunted & wasted 5.1%, underweight, stunted and wasted 10.2%. Maternal undernutrition was more common (95.7%) in undernourished children group. Undernutrition was significantly higher in mothers of children with undernutrition (OR=40.75, p<0.001). Children having a better nutrition were born from mothers who were well nourished, educated, had good childcare knowledge and higher family income. This emphasized the need to provide the guideline for appropriate measure to be taken to reduce child undernutrition.

Abstract
Hemoprotozoans are important pathogens of animals and humans, among which some species have zoonotic significance. The prevalence of different hemoprotozoa and Anaplasma spp. in larger mammals have been reported from different regions of the world. But, very few studies have been conducted to estimate the prevalence of hemoprotozoa in rodents and shrews of South-East Asia. The study assessed the prevalence of hemoprotozoa and Anaplasma spp. in rodents and shrews of Bangladesh. Blood samples (n=451) were collected from rodents and shrews between June 2011 and June 2013 and July-December 2015 from 4 land gradients of Bangladesh. Giemsa-stained blood smears revealed that 13% of animals were harboring hemoprotozoa (4.7% Babesia spp., 0.67% Plasmodium spp.), and Anaplasma spp. (7.5%). The study may serve as a guide for future hemoparasitic research of rodents and shrews.

Abstract
This cross-sectional descriptive study was conducted at the neonatal intensive care unit (NICU) in the department of Neonatology, Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2017 to December 2017 to determine antimicrobial sensitivity pattern in neonatal sepsis. Ninety four neonates (0-28 days) who were admitted in NICU with suspected sepsis were included in this study by purposive sampling technique. After admission written informed consent from parents or guardians obtained and then septic screening along with blood culture and antimicrobial sensitivity was done. All data were compiled, tabulated and then analyzed by SPSS version 21.0. Among 94 cases, 68(72.3%) were preterm and 26(23.4%) were term. There was male predominance and male female ratio was 1.9:1. Most of the patient admitted within 72 hours of birth. Most (84%) had low birth weight (<2500gm). Pre-mature onset of labour, pre-mature rupture of membrane >18 hours, vaginal route of delivery, instrumental resuscitation, pre-lacteal feeding, bottle feeding were the major perinatal risk factors in this study. Early onset sepsis (76.6%) was most prevalent in this study. Blood culture yielded positive growth in 20(21.3%) cases. Among them, Klebsiella was found in 7(35%). E. coli in 6(30%), Acinetobacter was in 3(15%), Staphylococcus aureus in 2(10%) cases. Pseudomonas and Enterobacter were found in rest 2(10%) of the cases. Gram negative bacteria were found in 18(90%) cases. Klebsiella was sensitive to Imipenem (85.7%), Colistin (85.7%) and Ciprofloxacin (77.5%). Sensitivity of E. coli was Imipenem (100%), Colistin (100%), Amikacin (66.7%), Ciprofloxacin (66.7%), Netilmicin (66.7%) and Gentamicin (50%). Acinatobecter had sensitivity to Netilmicin, Colistin, Imipenem (100%). Staphylococcus was 100% sensitive to Imipenem, Netilmicin and Vancomycin. Pseudomonas was found sensitive to Imipenem (100%), Amikacin (100%), Netilmicin (100%) and Colistin (100%). Enterobacter was found highly sensitive to Ciprofloxacin, Colistin and Imipenem. Almost all organisms were resistant to Ampicillin, Gentamicin, Cefotaxime and Ceftazidime. Based on result it is concluded that Klebsiella pneumoniae and Escherichia coli are the leading cause of neonatal sepsis in this study and most of them resistant to multiple antibiotics. Organisms found more sensitive to Imipenem, Colistin, Ciprofloxacin and Netilmicin.

Abstract
Purpose
The gradual increase in geriatric issues and global imbalance of the ratio between patients and healthcare professionals have created a demand for intelligent systems with the least error-prone diagnosis results to be used by less medically trained persons and save clinical time. This paper aims at investigating the development of image-based colourimetric analysis. The purpose of recognising such tests is to support wider users to begin a colourimetric test to be used at homecare settings, telepathology and so on.
Design/methodology/approach
The concept of an automatic colourimetric assay detection is delivered by utilising two cases. Training deep learning (DL) models on thousands of images of these tests using transfer learning, this paper (1) classifies the type of the assay and (2) classifies the colourimetric results.
Findings
This paper demonstrated that the assay type can be recognised using DL techniques with 100% accuracy within a fraction of a second. Some of the advantages of the pre-trained model over the calibration-based approach are robustness, readiness and suitability to deploy for similar applications within a shorter period of time.
Originality/value
To the best of the authors’ knowledge, this is the first attempt to provide colourimetric assay type classification (CATC) using DL. Humans are capable to learn thousands of visual classifications in their life. Object recognition may be a trivial task for humans, due to photometric and geometric variabilities along with the high degree of intra-class variabilities, it can be a challenging task for machines. However, transforming visual knowledge into machines, as proposed, can support non-experts to better manage their health and reduce some of the burdens on experts.

Abstract
Acetabular fracture usually occurs as a result of high velocity injury and often affects the young and economically productive population. Previously, treatment of acetabular fracture was grossly inadequate and many patients were left with incapacitating pain, limitation of movement. Proper management should be given in our set-up to save lives and to minimize long term complications and related disabilities. This study was done to evaluate the outcome of open reduction and internal fixation of posterior wall fracture of acetabulum. This prospective observational study was carried out in Dhaka Medical College Hospital, Dhaka, Bangladesh from July 2016 to June 2018. Total twenty five cases were selected. Radiological and functional outcome were evaluated six months after surgery according to Matta radiographic criteria and Merle d Aubigne and Postel criteria respectively. Effect of age, gender, hip dislocation, displacement of fracture fragment, associated injury, reduction quality, trauma to surgery time, complication of operation on the functional outcome was evaluated. Age range was 18-60 years. The mean age was 38±11 years. Male 23 and female 2, male and female ratio was 11.5:1. Mean follow up 8.5±1.7 months, range 6-12 months. According to Matta radiographic criteria, 6 months after surgery, 10 patients had excellent, 10 patients had good, 3 patients had fair and 2 patients had poor radiological outcome. According to Merle d Aubigne and Postel criteria, 6 months after surgery, 11 patients had excellent, 10 patients had good, 3 patients had fair and 1 patient had poor functional outcome. Overall functional outcome of the study population revealed that 21 patients (84%) belonged to satisfactory (Excellent + Good) and 4 patients (16%) belonged to unsatisfactory (Fair + Poor) outcome. AVN (avascular necrosis) of femoral head had been occurred in two patients, post-operative wound infection had been occurred in two patients and myositis ossificans around hip joint had been occurred in two patients. Twenty (20) patients were achieved anatomic (0, 1mm) reduction, 3 patients were achieved imperfect (2, 3mm) reduction and 2 patients were achieved poor (>3mm) reduction. This study concludes that open reduction and internal fixation of posterior wall fracture of acetabulum is a satisfactory method of treatment.

Abstract
Acinetobacter species are important opportunistic and nosocomial pathogens capable of causing both community and health care-associated infections. The aim of this study was to determine the prevalence of Acinetobacter species and determination of the antibiotic susceptibility patterns of Acinetobacter. A total of 341 specimens were collected over a period of one year from January 2017 to January 2018 from ICU and Surgery unit of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Antimicrobial susceptibility testing of all Acinetobacter isolates was done using Kirby Bauer's disc diffusion technique as per recommendations of Clinical Laboratory Standards Institute (CLSI). MIC of commonly used Imipenem and newly introduced Tigecycline by agar dilution method was done and was compared it with disc diffusion method. From total 341 specimens, 119(34.8%) pathogen were isolated. Among 119 isolates total 46(38.6%) Acinetobacter were isolated. Maximum number of Acinetobacter was isolated from respiratory samples- endotracheal secretions. Regarding antimicrobial resistance, 42(91.3%), 33(71.7%), 20(43.5%), 28(60.9%) and 1(2.2%) were resistant to Piperacillin-Tazobactam, Doxycycline, Imipenem, Colistin and Tigecycline. Regarding, MIC of Imipenem, 41.3% was resistant, 32.6% was intermediate and 26.1% was sensitive. Regarding MIC of Tigecycline none was resistant, 39.1% was intermediate and 60.9% was sensitive. Acinetobacter species is emerging as a predominant healthcare associated multidrug resistant pathogen. The findings of this study will help our clinicians to apply appropriate antibiotics for treatment of patients.

Abstract
Spirulina platensis is one of the most promising microalgae for culture due to its high nutritional values. The main constraint to its production is the high cost of culture media. Therefore, an experiment was conducted to evaluate the growth performance of S. platensis with the aim of replacing sodium bicarbonate (NaHCO3) and mineral nutrients in Kosaric medium (KM) with banana leaf ash extract. KM was used as control medium in treatment T1. In treatments T2 to T5, 50% of NaHCO3 in KM was replaced with banana leaf ash extract (BLAE). In addition, micronutrients in KM were reduced to 75%, 50% and 25% in treatments T3 to T5, respectively. The values of different physical and chemical parameters (temperature, pH, dissolved oxygen and light intensity) of the culture media were within the suitable range for S. platensis culture. Optical density in treatments T2 and T3 were similar to that was in treatment T1. Maximum cell dry weight (0.65 gL-1) was observed in treatment T1 and it was similar to the treatments T2 and T3 where 50% of NaHCO3 in KM was replaced with banana leaf ash extract with 100% and 75% micronutrients supply, respectively. The similar trend was found in chlorophyll a content. It was evident that 50% of NaHCO3 in KM can be replaced with BLAE for the culture of S. platensis, in addition micronutrients in KM can be reduced to 75%.

Abstract
As rice is an important staple food globally, research for development and enhancement of its nutritional value it is an imperative task. Identification of nutrient enriched rice germplasm and exploiting them for breeding programme is the easiest way to develop better quality rice. In this study, we analyzed 113 aromatic rice germplasm in order to identify quantitative trait loci (QTL) underpinning nutrition components and determined by measuring the normal frequency distribution for Fe, Zn, amylose, and protein content in those rice germplasm. Comparatively, the germplasm Radhuni pagal, Kalobakri, Thakurbhog (26.6 ppm) and Hatisail exhibited the highest mean values for Fe (16.9 ppm), Zn (34.1 ppm), amylose (26.6 ppm) and protein content (11.0 ppm), respectively. Moreover, a significant linear relationship (R2 = 0.693) was observed between Fe and Zn contents. Cluster analysis based on Mahalanobis D2 distances revealed four major clusters of 113 rice germplasm, with cluster III containing a maximum 37 germplasm and a maximum inter-cluster distance between clusters III and IV. The 45 polymorphic SSRs and four trait associations exhibited eight significant quantitative trait loci (QTL) located on eight different chromosomes using composite interval mapping (CIM). The highly significant QTL (variance 7.89%, LOD 2.02) for protein content (QTL.pro.1) was observed on chromosome 1 at 94.9cM position. Also, four QTLs for amylose content were observed with the highly significant QTL.amy.8 located on chromosome 8 exhibiting 7.2% variance with LOD 1.83. Only one QTL (QTL.Fe.9) for Fe content was located on chromosome 9 (LOD 1.24), and two (QTL.Zn.4 and QTL.Zn.5) for Zn on chromosome 4 (LOD 1.71) and 5 (LOD 1.18), respectively. Overall, germplasm from clusters III and IV might offer higher heterotic response with the identified QTLs playing a significant role in any rice biofortification breeding program and released with development of new varieties.

Abstract
PurposePhishing attacks have evolved in recent years due to high-tech-enabled economic growth worldwide. The rise in all types of fraud loss in 2019 has been attributed to the increase in deception scams and impersonation, as well as to sophisticated online attacks such as phishing. The global impact of phishing attacks will continue to intensify, and thus, a more efficient phishing detection method is required to protect online user activities. To address this need, this study focussed on the design and development of a deep learning-based phishing detection solution that leveraged the universal resource locator and website content such as images, text and frames.Design/methodology/approachDeep learning techniques are efficient for natural language and image classification. In this study, the convolutional neural network (CNN) and the long short-term memory (LSTM) algorithm were used to build a hybrid classification model named the intelligent phishing detection system (IPDS). To build the proposed model, the CNN and LSTM classifier were trained by using 1m universal resource locators and over 10,000 images. Then, the sensitivity of the proposed model was determined by considering various factors such as the type of feature, number of misclassifications and split issues.FindingsAn extensive experimental analysis was conducted to evaluate and compare the effectiveness of the IPDS in detecting phishing web pages and phishing attacks when applied to large data sets. The results showed that the model achieved an accuracy rate of 93.28% and an average detection time of 25 s.Originality/valueThe hybrid approach using deep learning algorithm of both the CNN and LSTM methods was used in this research work. On the one hand, the combination of both CNN and LSTM was used to resolve the problem of a large data set and higher classifier prediction performance. Hence, combining the two methods leads to a better result with less training time for LSTM and CNN architecture, while using the image, frame and text features as a hybrid for our model detection. The hybrid features and IPDS classifier for phishing detection were the novelty of this study to the best of the authors' knowledge.

Abstract
OBJECTIVE: To compare the occurrence of unfavourable treatment and safety outcomes of double-dose rifampicin (RMP; 20 mg/kg/d, intervention) with standard dose (10 mg/kg/d, control) in a first-line tuberculosis (TB) treatment regimen for smear-positive TB patients in Bangladesh.DESIGN:
This was a randomised clinical trial. The primary efficacy and safety endpoints were the occurrence of an unfavourable treatment outcome (death, failure, relapse or loss to follow-up) and the occurrence of any serious drug-related adverse event (SAE).RESULTS: In primary efficacy
analysis, among 343 control and 347 intervention patients, respectively 15.5% and 11.8% had an unfavourable outcome. In safety analysis, among 349 intervention and 352 control patients, respectively 4.3% and 2.6% experienced an SAE. These differences were not significant. There was a significantly
lower occurrence of SAEs, explained by a lower occurrence of hepatic toxicity, in a RMP double-dosed but erroneously HZE (isoniazid+pyrazinamide+ethambutol) under-dosed subgroup.CONCLUSIONS: Our findings show that there is no statistically significant difference in terms of efficacy
and safety between standard and double-dose RMP. An accidental finding (related to dosage levels of the standard regimen) suggests that high-dose RMP is potentially a lesser cause of hepatotoxicity. Larger trials with more power, or trials with at least a triple-dose might be needed to clearly
see the effect of high-dose RMP on unfavourable outcomes.

Abstract
Pollution in rapidly urbanising cities and in delta systems is a serious problem that blights the lives and livelihoods of millions of people, damaging and restricting potable water supply and supplies to industry (Whitehead et al, 2015, 2018). Employing new technology based on luminescent molecular biosensors, the toxicity in the rivers around Dhaka in Bangladesh, namely the Turag, Tongi, Balu and Buriganga, has been assessed. Samples taken at 36 sites during medium and low flow conditions and during the Bishwa Ijtema Festival revealed high levels of cell toxicity, as well as high concentrations of metals, particularly aluminium, cadmium, chromium, iron, zinc, lithium, selenium and nickel. Chemical analysis also revealed low dissolved oxygen levels and anoxic conditions in the rivers at certain sites. The bacterial molecular biosensors were demonstrated to be fast, with results in 30 min, robust and a highly sensitive method for the assessment of water toxicity in the field. Furthermore, the biosensor toxicity analysis correlated with the metals data, and a multivariate regression relationship was developed relating toxicity to key metals, such a selenium, zinc and chromium. The resulting model has been validated against split samples and the Bishwa Ijtema Festival data. The combination of modelling and the molecular biosensor technology provides a new approach to detecting and managing pollution in urban river systems.

Abstract
Hypertension (HTN) is an important cause of cardiovascular mortality and the prevalence of hypertension is increasing particularly in middle- and low-income countries including Bangladesh. No data are available for the prevalence of hypertension among the government employees in Bangladesh. In this cross-sectional study, conducted from 30 October to 31 December 2016, 1219 government employees aging ≥18 years working in Rangpur city were evaluated for the presence of HTN and its risk factors. Socio-demographic and anthropometric data, data on the presence of various known risk factors of hypertension were collected. Hypertension was defined with systolic BP ≥140mmHg and/or diastolic BP ≥90mmHg or those getting treatment for hypertension. Statistical analysis was done by using SPSS version 23.0; odds of hypertension among subjects with risk factors were calculated and p ≤0.05 was considered to be statistically significant. The prevalence of hypertension was 38.3% among the study subjects. Significantly higher odds of having hypertension were observed in study subjects with the age groups of 35-49 (OR 2.12, 95% CI: 1.51-2.99, p<0.001) and ≥50 (OR: 4.96, 95% CI: 3.43-7.18, p<0.001) years than age group <35 years. Employees who were averagely satisfied and not satisfied for their jobs also had higher odds (OR: 1.38, 95% CI: 1.00-1.91, p=0.049 and OR: 1.48, 95% CI: 3.43-7.18, p=0.337) of having hypertension than fully satisfied ones. Having diabetes mellitus was found to increase the odds (OR 2.12, 95% CI: 1.51-2.99, p<0.001) of hypertension. Male gender, urban/suburban residence, not doing physical exercise, sedentary/light working habit, overweight/obesity also increased the odds of having hypertension though these were not statistically significant. There is a high burden of hypertension among the government employees in Rangpur city. Age, job satisfaction and diabetes were independent risk factors of hypertension.

Abstract
Acute post-streptococcal glomerulonephritis (APSGN) is the commonest cause of acute glomerulonephritis (AGN), which usually present with gross hematuria, mild edema, oliguria, hypertension and varying degree of renal insufficiency. It is more common among the population of school going age where poverty, overcrowding and poor hygienic conditions are prevailing. This cross sectional observational study was aimed to know the socio-demographic variables, clinical profile and immediate outcome of AGN in hospitalized children and was conducted in the Pediatric department of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from November 2014 to April 2015. A detailed history was taken from the parents in each case with a written questionnaire. A written consent was also taken from the guardian of the including patients and also permission was taken from the ethical committee of MMCH. Thorough clinical examination and available relevant investigations were done in all patients. Progresses of the patient were monitored by daily clinical examinations and also by investigations. Data were analyzed by statistical package for social science (SPSS) windows version 18. Results were verified by doing standard test for significance. Among total 60 cases male was 58.3% & female was 41.7%. The common age group of presentation was between 7-12 years (73%), peak age of incidence was 7-9 years. Most of them came from low socioeconomic status (83.3%), 63.3% from rural area with average 5-6 member's family size. Most of the parents were illiterate. History of (H/O) skin infection was present in 35(58.3%) patients, 15(25%) had H/O sore throat, 15% did not give any H/O infection before presentation. Average duration of gap between infection and appearance of clinical feature was 7-14 days in 73.40%and 15-21 days was in 45.7% in case of sore throat & skin infection respectively. Almost all (95%) patients presented with puffiness of face, others presented with scanty micturition, gross hematuria, respiratory distress, fever, convulsion and altered sensorium. Edema (75%), hypertension (88.3%), pallor (38%), tachypnea (25%), tachycardia (26.7%) were the important clinical findings. Microscopic hematuria was present among 96.66% patients; low complement level was found in 85% cases. There is significant association between low socioeconomic statuses with more hospital stay. Only one patient died due to heart failure and 98.3% patient had complete recovery. Results of this study conclude that most of the patients came from rural illiterate family with low socioeconomic background. Skin infection is the commonest cause of acute glomerulonephritis. Edema, scanty micturation, hematuria and hypertension are the common mode of presentation. Heart failure and hypertensive encephalopathy are the common complication of AGN. Immediate prognosis of AGN was excellent.

Distal humeral fractures are relatively rare injuries that constitute approximately 2% of all fractures which occur due to high energy trauma in young males. Because they involve the articular surface and usually cause an instable elbow, surgical treatment is necessary for the recovery of elbow functions in the majority of cases. The principles of absolute stabilization and early mobilization in the elbow are of more importance than in any other joint. As the AO classification, nonunion and implant loosening is more common in type C fractures of the distal humerus involving the joint surface. Aim of this prospective study was to evaluate the outcome of "Double Tension Band wiring" method for the treatment of intercondylar fractures of humerus and was conducted in a tertiary hospital of Bangladesh from July 2017 to June 2019. Twenty five patients, all presenting with fresh fractures of the distal humerus, treated with double tension band wiring. These patients were prospectively evaluated over a period of at least 6 months. Fractures were classified according to Jupiter classification and AO classification of distal humeral fractures. Due to AO classification, total fractures were C1 fractures. Average age of the patients was 56.20 years (32-70 years). There were 20 males and 5 females. Out of 25 cases treated with this method, rigid fixation and union was achieved in all of them. The average tourniquet time was 69 minutes range was minimum 50 minutes and maximum 120 minutes. Radiological union was achieved at an average of 14.2 weeks (10-18 weeks). Average range of motion was 112.8 degrees (107-116). Excellent to good results were seen in almost 86% of cases as per the Mayo Elbow performance score at 6-month follow-up. Wound infection had been occurred in 2(8%) cases, ulnar nerve neuropathy had been occurred in 1 case, delayed union of olecranon process of ulna had been occurred in 1(4%) case, implant failure had been occurred in 2(8%) cases, heterotrophic ossification had been occurred in 2(8%) cases, varus valgus instability had been occurred in 1(4%) case, gun stock deformity had been occurred in 2(8%) cases. Double tension band wiring is a reliable, less demanding and cost effective method of fixation of intercondylar fractures of humerus.

Abstract
NiO alloyed with aluminum, Ni1−xAlxO, is analyzed in terms of its stoichiometry, electronic and transport properties, as well as interfacial band alignment with Si to evaluate its potential use as a hole transport layer (HTL) in p–i–n type solar cells. The analysis is based on component material and slab structural simulations, as well as simulated and measured angle-resolved valence-band photoemission spectroscopy (PES) data, in order to reveal the best suitable stoichiometry. It is concluded that the ionization energy from the highest occupied states tends to increase with Al content as the simulated work function grows from 4.1 eV for pure NiO to 4.7 eV for heavily alloyed Al0.50Ni0.50O. The electronic structure as a function of the interface design between crystalline silicon and the transport layer is used to assess the band lineup and its correlation with the discontinuity of the affinities. The affinity rule is tested by evaluating the workfunctions of the component layers and justified best for a particular Ni-enriched interface design. Technology Computer-Aided Design (TCAD) device simulations show, that the band offset between oxide and crystalline silicon remains within the range of values to sustain a staggering alignment – a condition suitable for effective charge separation, similar to a situation in a tunneling diode. The self-energy of the hole carriers is estimated by contrasting simulated and measured photoemission data, which in the case of non-annealed Al-rich samples is shown to be an order of magnitude higher due to the disorder effects. The work functions derived from the measured PES data for the epitaxially grown oxide films with nearly identical alloy stoichiometry correlate well with the simulated values. The findings suggest that the optimal HTL is formed by starting with a pure Ni layer, followed by a graded doping AlxNi1−xO, with x high at contact/oxide interface and low at the oxide/semiconductor. NiO alloyed with aluminum, Ni1−xAlxO, is analyzed in terms of its stoichiometry, electronic and transport properties, as well as interfacial band alignment with Si to evaluate its potential use as a hole transport layer (HTL) in p–i–n type solar cells.![]()

Abstract
Heavy metal pollution from tanneries is a global problem in many rapidly developing economies. Effluent discharges into rivers cause serious problems for water quality, damaging ecology and threatening the livelihoods of people, especially in developing urban centres which often have a high concentration of factories. The industry intensive capital area of Bangladesh is impacted with high levels of metals pollution in rivers in the Greater Dhaka Watershed. Sampling and modelling studies have been undertaken to assess pollution in the Buriganga River System in Dhaka. The process based, dynamic model INCA (Integrated Catchments) model has been used to simulate metals along the Buriganga River System in Central Dhaka. Observed and simulated metals concentrations are high, and the model shows that the proposed transfer of the tannery industry upstream helps to reduce the pollution significantly downstream. However, moving the industry upstream may be counterproductive as it is discharged into the upper reaches of the river. This will create pollution upstream unless the newly constructed effluent treatment system can operate at a high level.

Abstract
Tuberculosis is a common cause of death in developing countries like Bangladesh. About 30% of pulmonary tubercular infected patients developed tubercular pleural effusion. Tubercular pleural effusion was diagnosed by cytological, biochemical and bacteriological methods. But these methods showed low sensitivity. In some cases pleural biopsy showed also negative results. Now a days molecular technique like Polymerase chain reaction (PCR) is promising method for diagnosis of pleural TB. PCR was done in 100 pleural fluid collected from suspected tubercular pleural effusion cases admitted in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2011 to January 2013. Among the 100 samples 3% were culture positive and PCR positive was 6%. Sensitivity and Specificity of PCR considering culture as a gold standard method was 100% and 96.71% respectively in this cross sectional study. Among them Adenosine deaminase (ADA) level is >40IU/L in all PCR positive sample. Where PCR is available, measurement of ADA activity as well as PCR can be done simultaneously.

Abstract
Although esthetic factors might limit by the presentation of materials used, all-metal complete cast crown should always be offered to patients requiring restoration of endodontically treated posterior tooth. The complete cast crown has the highest longevity of all fixed restorations. It could be used to rebuild a single tooth or a retainer for a fixed prosthesis. It involves all the axial walls as well as the occlusal surface of the tooth to be restored. All restorations are placed in the oral environment in contact with the gingival tissue. Thus clinicians must choose nontoxic or least toxic metal alloys, since any release of elements that might cause reactions. This study was designed to observe clinical responses of nickel chromium alloy and gold alloy cast crown and provide guidance to ascertain the best alloy for cast metal crown, which serves better functional restoration.

Abstract
Cardiofacial syndrome is associated with facial abnormality with congenital heart disease. Here, we report a case of cardiofacial syndrome having anotia and facial nerve palsy on the right side in combination with infundibular pulmonary stenosis and patent ductus arteriosus which is a rare presentation of cardiofacial syndrome. A 6 years old girl presented to department of Cardiac surgery of Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh with the complaints of shortness of breath on exertion since 2 years of age. Her physical examination revealed right sided anotia and facial nerve palsy associated harsh ejection systolic murmur in upper left parasternal area. Echocardiography showed critical infundibular pulmonary stenosis with a small patent ductus arteriosus. She underwent ligation of patent ductus arteriosus and excision of infundibular muscular bands and discharged to home without any complication. Any child presented with facial abnormality should be checked for any cardiac abnormality for early intervention and better management of the patient.

Abstract
Scrub typhus is a mite-borne rickettsial disease caused by Orientia tsutsugamushi, which is endemic in Asia Pacific region. In this study, infection rate and molecular epidemiologic traits of O. tsutsugamushi was investigated in Mymensingh, located in north-central Bangladesh. Among the blood samples from 453 febrile patients who visited Mymensingh medical college hospital in 2018, the 47 kDa protein gene of O. tsutsugamushi was detected in 78 samples (17.2%) by nested PCR. Phylogenetic analysis of the O. tsutsugamushi 56 kDa protein gene (18 samples) revealed a predominance of Karp-related genotype (89%), while the remaining belonged to Gilliam genotype. Samples of the Karp-related genotype mostly clustered with those of China, Taiwan, Thailand and India, etc., in emergent subgroups clades 2 and 4, which were distinct from clade 1, including prototype Karp strains. Among the 18 samples, three variable domains (VD) of 56 kDa type-specific antigen had different types of sequence diversity; VDI contained two or three repeats of eight amino acid units, while VDII and VDIII had amino acid substitution, deletion or insertion. The present study documented a potentially high prevalence of genetically diverse O. tsutsugamushi in north-central Bangladesh.

Abstract
Background:
B7-33 is a peptide derived from the B-chain of human relaxin, and is shown to elicit biased signaling at relaxin receptor 1 (RXFP1) in human cell lines. The influence of B7-33 on myocardial ischemia-reperfusion (IR) injury and associated cardiac adverse remodeling is unknown.
Methods and Results:
Primary cardiomyocytes and cardiac fibroblasts were isolated from adult CD1 mice and subjected to simulated ischemia-reoxygenation (SIRO). Myocytes were placed in 1% O
2
chamber for 40 min, followed by 1 h of reoxygenation with control (myocyte media) or B7-33 (10, 50 or 100 nM)-infused media. Trypan blue staining showed a significant decrease in cell death with B7-33 concentrations of 50 nM and 100 nM (
Fig. A
).Treating myocytes with B7-33 for 15 min exhibited a dose-dependent increase in Erk1/2 phosphorylation, which reached statistical significance at 100 nM (
Fig. B
). Fibroblasts subjected to 4 h of hypoxia and 15 h of reoxygenation had increased viability (MTT assay) with B7-33 at all concentrations (
Fig. C
).
In vivo
, CD1 mice were subjected to IR injury via coronary artery ligation for 30 min, followed by 24 h of reperfusion. Vehicle (saline) or B7-33 (10 μg/kg) was injected i.p. at the onset of reperfusion. After 24 h, B7-33-treated mice demonstrated decreased infarct size (TTC stain) (
Fig. D
) and preserved fractional shortening (M-mode echo,
Fig. E
) compared to vehicle-treated mice.
Conclusion:
Reperfusion therapy with B7-33 reduces infarct size post-MI, preserves cardiac function and protects cardiomyocytes and fibroblasts against SIRO. We propose that B7-33 might be effective against acute MI and a possible alternative to recombinant relaxin for clinical utility.

Abstract
In world wide cervical cancer is the fourth most common among women, with the majority of cases occurring in developing countries. Some HPV infections persist, and a subset of persistent infections may lead to development of cervical intraepithelial neoplasia (CIN) or invasive cancer. Because neoplastic change typically takes some years to occur and it depends on multiple factors among them age and parity play important role. The objective of the cross sectional observational study was detection of oncoprotein depending on age and parity by immunochromatographic test (OncoE6 cervical test). Informed consent was taken from patients and the protocol was approved by IRB, Mymensingh Medical College, Mymensingh, Bangladesh. From April 2016 to March 2017 following universal safety precautions a total of 280 endocervical swabs were collected from VIA outdoor and Colposcopy clinic of Obstetrics and Gynaecology department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh. Laboratory work was done in the department of Microbiology, Mymensingh Medical College. The E6 strip test is an immunochromatographic test based on the detection of HPV-E6 oncoprotein in cervical swab samples. In this study VIA and OncoE6 cervical test were done on 280 cases and among them 120 were VIA positive and sent for colposcopy. From 120 VIA positive cases 70 were positive for colposcopy test. Afterwards 50 cases were selected for histopathological examination and classified into different grades. The present study showed 21(7.5%) cases were OnE6 cervical test positive by OncoE6 cervical test and most of them were found in advance aged <50 (38.09%) and multi parity (women more than two, 32.5%). Based on the findings of the present study, it may be concluded that age and multi parity plays important factor to cause cervical cancer. Now for prevention of cervical cancer we need screening which is an early detection tool. This is a low cost device, easily performed which can detect this HRHPV (High Risk HPV) and it will be helpful to reduce over treatment and high predictability of the disease.

Abstract
Health is multifactorial and influenced by nutritional, biological, chemical and psychological factors. It is quite true that environment has direct impact on those diseases that are the outcome of man's maladjustments to his environment. Often man is responsible for pollution of environment through urbanization, industrialization and other human activities. Improvement of environmental condition is one of the best ways to prevent some of the diseases prevailing in our country. The study was designed to explore the environmental situation of rural area of Bangladesh. The descriptive cross sectional study was conducted in purposively selected six villages of Dewanganj Upazila of Jamalpur district, Bangladesh during the period of January 2018 to February 2018. A total of 227 purposively selected women having at least one under five children were interviewed face to face using a semi-structured questionnaire. Mean±SD age of the respondents was 27.31±6.4 years. About three fourth (167, 73.57%) of the respondents were literate while one fourth (60, 26.43%) of them were illiterate. On the other hand about two third (149, 65.64%) of husbands were literate and remaining (78, 34.36%) were illiterate. The most (215, 94.71%) of the respondents were housewives. Majority (143, 62.99%) of them had children of less than 3 and mean±SD age of children was 2.85±1.17 years. Majority (140, 61.67%) of the respondents belonged to nuclear family while 86 (37.89%) belonged to joint family. Mean±SD family member was 6.42±8.12 persons. The mean monthly family income was BDT 8066.52 with a standard deviation of BDT. 6767.12. Out of 277 respondents, almost half 110(48.46%) of them lived in mixed houses followed by 92(40.53%) and 25(11.01%) lived in Kantcha & Pucca houses respectively. The most (180, 79.30%) of the respondents were used separate kitchen in their houses. About two forth (171, 75.33%) of the respondents did not have any kitchen garden. All 227(100.0%) of the respondents were used tube well as source of drinking water. The most (211, 92.95%) of the respondents got supply water within their compounds. All of the respondents got water supply within 15 minute walking distance. Majority 149(65.64%) of the respondents used sanitary toilets & 40(17.62%) used pit latrines and rest 30(13.22%) of them practiced open air disposal. More than half (118, 51.99%) of the respondents' children were not using toilets for excreta disposal. Efforts are needed to increase environmental health related knowledge and awareness to maintain environment sanitation. People should use sanitary latrines and avoid practice of open air disposal of children's feces to prevent excreta borne diseases. Further wider scale details study is needed to formulate policy in regards to improve the environmental sanitation of Bangladesh.

Abstract
Here, we report a case of a right atrial myxoma attached to the lateral wall, which is seen in only 10% cases, impinging upon the tricuspid valve. A 57 year old male normotensive, non-diabetic, nonsmoker patient was presented to us on 5th of August 2018 with the complaints of cough, dyspnea and orthopnea for the last two years. This type of presentation is very rare. After excision of myxoma, there was a significant improvement in the signs and symptoms of the patient. In this report, we emphasize the rarity of myxoma in the Right Atrium, and its difficulty in diagnosis because of its uncommon location and atypical presentation, surgical management has shown to quickly alleviate the majority of symptom and expectant sequeale.

Abstract
Leptospiral 16S rRNA genes were detected in 13 blood samples from 74 febrile patients in north-central Bangladesh, and their sequences phylogenetically clustered with those of Leptospira interrogans or Leptospira wolffii. Genetic diversity in O-antigen polymerase (wzy) was found in an L. interrogans sample.

Abstract
Vitamin D is essential for the body to regulate calcium and phosphate levels and mineralization of bone. It is synthesized in the skin after ultraviolet radiation exposure or obtained in the diet to a less extent. Vitamin D deficiency is attracting attention due to higher prevalence in different populations. Physicians of Bangladesh are supposed to be vulnerable to low Vitamin D levels owing to long indoor work hours in both government and private settings. The study was conducted to evaluate Vitamin D status among physicians working in a tertiary level public hospital of Bangladesh. The cross sectional descriptive study was carried out at Mymensingh Medical College Hospital during the period of January 2018 to June 2018. Data were collected from purposively selected 102 doctors of different levels using a case record form. Interview, measurements and laboratory investigations were done accordingly. Vitamin D levels were categorized as deficient (<20.00ng/L), Insufficient (20.00-29.00ng/L), Sufficient (30.00-100.00ng/L) and Potential Toxicity (>100.00ng/L). Among 102 doctors 79(77.5%) were male and 23(22.5%) were female. Maximum (60.8%) were in the age group of 31 years to 50 years. Mean±SD age of the subjects was 49.9±3.61years. Vitamin D deficiency was found in 19(18.6%) subjects and insufficiency was in 49(48.0%) of the subjects. On the other hand 34(33.3%) subjects had sufficient Vitamin D levels. Potential Vitamin D toxicity was not found in any of the subjects. Vitamin D deficiency was found more in female (30.4%) than male (15.2%) but insufficiency was found more in male (50.6%) than female (39.1%). The study revealed that 66.6% physicians had either deficiency or insufficiency of Vitamin D. Exposure to sunlight, dietary intake and Vitamin D supplementation should be considered to increase the status of Vitamin D levels in Physicians of Bangladesh.

Abstract
Acute exacerbations of COPD is characterized by a change in the patients baseline dyspnoea, cough and/or sputum that is beyond normal day to day differences and guides to a change in standard medications in a patient with COPD. Vitamin D influences the innate & adaptive immune system, and exerts pleiotropic antimicrobial and anti-inflammatory responses. Vitamin D deficiency is frequent among COPD patients but its contributory role in disease exacerbations is widely debated. This study was aimed to assess relationship between reduced serum vitamin D (25-OHD) level with COPD severity and acute exacerbation. This observational cross-sectional study was carried out in the department of Respiratory Medicine, NIDCH, Mohakhali, Dhaka, Bangladesh from October 2016 to September 2017. Consecutive 80 hospital admitted patients with acute exacerbation of chronic obstructive pulmonary disease diagnosed on the basis of clinical history & pulmonary function tests and 78 age & sex matched controls were investigated for serum vitamin D (25-OHD) level. Among the COPD patients, 37% had Vitamin D deficiency (<20ng/ml) and 28.75% had Vitamin D insufficiency (20-29ng/ml). Mean vitamin D (25-OHD) level of COPD patients (25.82±10.62ngm/ml) was found to be significantly lower than healthy controls (32.57±11.32ngm/ml). Vitamin D deficiency was found, by Pearson correlation test, to be significantly associated with severity of COPD. Multivariate analysis showed that age (in years), FEV1 (percent predicted), frequent exacerbators (≥2 in the last year), and smoking (>40 pack year) were significantly associated with Vitamin D deficiency. Acute exacerbation of chronic obstructive pulmonary disease patients was found to have vitamin D deficiency and vitamin D deficiency was significantly associated with severity of COPD. Vitamin D deficiency was also associated with frequent disease exacerbation.

Abstract
A male patient about 45 years old came to my private clinic "The Dental Aid", Dhanmondi, Dhaka, Bangladesh last year (February 2016) with the complaint of pain at right palatal premolar region. On clinical examination we found the absence of upper left 2nd premolar from the series of dentition but on the right side premolars are present. The oral mucosa was intact and normal in color. There was no caries, dental pocket or any other pathology in the teeth of both jaws. On palpation we found soft area on the right palatal side at the premolar area. We took intraoral peri-apical radiograph and found impacted left 2nd premolar whose crown was encircled by radiolucent area at the palatal side. Here, we present a rare case of transmigrated and impacted left 2nd maxillary premolar associated with dentigerous cyst. The cyst was successfully treated under general anaesthesia by enucleation along with extraction of the involved maxillary transposed and impacted left second premolar.
