Abstract
BACKGROUND The COVID-19 pandemic has imposed unprecedented suffering on social and individual levels worldwide. Vaccines against COVID-19 have been prioritized as a crucial strategy for ending the pandemic as well as minimizing its consequences. OBJECTIVES This study aimed to determine the uptake of COVID-19 vaccine among high-risk urban populations in Southern Thailand using the Capability, Opportunity, Motivation, and Behavior (COM-B) model. METHODS We conducted a web-based cross-sectional study in the Hat Yai district, Songkhla province in Southern Thailand, in September and October 2021. The questionnaire was composed of sections on sociodemographic characteristics, COVID-19 vaccination status, and COM-B constructs. We employed a multivariable logistic regression analysis to determine factors associated with the uptake of the COVID-19 vaccine. We set statistical significance at p < 0.05. RESULTS In this study, females constituted 54.7% of the total participants (n = 358), and nearly half of the participants (45.8%) were in the younger age group (18-29). Of all the participants, 59.5% (95%CI: 54.2%-64.6%) received at least one dose of the COVID-19 vaccine. Factors associated with the uptake of COVID-19 vaccine and their adjusted OR (95% CI) were being married: 3.59 (2.06-6.24), having a graduate degree: 2.34 (1.38-3.96), gainfully employed: 3.30 (1.91-5.67), having a high level of opportunity: 2.90 (1.48-5.66), and having a high level of motivation: 2.87 (1.17-17.08). CONCLUSION The uptake of COVID-19 vaccines was moderate in this population. Moreover, the results showed that the COM-B model is useful in predicting COVID-19 vaccine uptake. The findings of this study could be used to aid future public health interventions in any event of outbreaks similar to COVID-19 disease in Thailand and beyond.

Abstract
Paederia foetida is valued for its folk medicinal properties. This research aimed to assess the acute toxicity, hypoglycemic and anti-hemostasis properties of the methanolic extract of P. foetida leaves (PFLE). Acute toxicity of PFLE was performed on a mice model. Hypoglycemic and anti-hemostasis properties of PFLE were investigated on normal and streptozotocin-induced mice models. Deep learning, molecular docking, density functional theory, and molecular simulation techniques were employed to understand the underlying mechanisms through in silico study. Oral administration of PFLE at a dosage of 300 µg/kg body weight (BW) showed no signs of toxicity. Treatment with PFLE (300 µg/kg/BW) for 14 days resulted in a hypoglycemic condition and a 30.47% increase in body weight. Additionally, PFLE mixed with blood exhibited a 44.6% anti-hemostasis effect. Deep learning predicted the inhibitory concentration (pIC50, nM) of Cleomiscosins against SGLT2 and FXa to be 7.478 and 6.017, respectively. Molecular docking analysis revealed strong binding interactions of Cleomiscosins with crucial residues of the target proteins, exhibiting binding energies of -8.2 kcal/mol and -7.1 kcal/mol, respectively. ADME/Tox predictions indicated favorable pharmacokinetic properties of Cleomiscosins, and DFT calculations of frontier molecular orbitals analyzed the stability and reactivity of these compounds. Molecular simulation dynamics, principal component analysis and MM-PBSA calculation demonstrated the stable, compact, and rigid nature of the protein-ligand complexes. The methanolic PFLE exhibited significant hypoglycemic and anti-hemostasis properties. Cleomiscosin may have inhibitory properties for the development of novel drugs to manage diabetes and thrombophilia in the near future.

Abstract
BACKGROUND Over the past few decades, diabetes has become a serious public health concern worldwide, particularly in Bangladesh. The advancement of artificial intelligence can be reaped in the prediction of blood glucose levels for better health management. However, the practical validity of machine learning (ML) techniques for predicting health parameters using data from low- and middle-income countries, such as Bangladesh, is very low. Specifically, Bangladesh lacks research using ML techniques to predict blood glucose levels based on basic noninvasive clinical measurements and dietary and sociodemographic information. OBJECTIVE To formulate strategies for public health planning and the control of diabetes, this study aimed to develop a personalized ML model that predicts the blood glucose level of urban corporate workers in Bangladesh. METHODS Based on the basic noninvasive health checkup test results, dietary information, and sociodemographic characteristics of 271 employees of the Bangladeshi Grameen Bank complex, 5 well-known ML models, namely, linear regression, boosted decision tree regression, neural network, decision forest regression, and Bayesian linear regression, were used to predict blood glucose levels. Continuous blood glucose data were used in this study to train the model, which then used the trained data to predict new blood glucose values. RESULTS Boosted decision tree regression demonstrated the greatest predictive performance of all evaluated models (root mean squared error=2.30). This means that, on average, our model's predicted blood glucose level deviated from the actual blood glucose level by around 2.30 mg/dL. The mean blood glucose value of the population studied was 128.02 mg/dL (SD 56.92), indicating a borderline result for the majority of the samples (normal value: 140 mg/dL). This suggests that the individuals should be monitoring their blood glucose levels regularly. CONCLUSIONS This ML-enabled web application for blood glucose prediction helps individuals to self-monitor their health condition. The application was developed with communities in remote areas of low- and middle-income countries, such as Bangladesh, in mind. These areas typically lack health facilities and have an insufficient number of qualified doctors and nurses. The web-based application is a simple, practical, and effective solution that can be adopted by the community. Use of the web application can save money on medical expenses, time, and health management expenses. The created system also aids in achieving the Sustainable Development Goals, particularly in ensuring that everyone in the community enjoys good health and well-being and lowering total morbidity and mortality.

Abstract
Among other valvular heart disease Aortic stenosis (AS) is the most common in the developed world. Transcatheter Aortic Valve Replacement (TAVR) is most acceptable treatment option for patient with severely calcified aortic stenosis with high and intermediate risk group. Among several challenges, one of the main challenges is to deal with bicuspid aortic valve (BAV). Non-circular annulus, bulky leaflets leading to perivalvular leaks and risk for rupture and often very severe calcification may contribute to periprocedural strokes leading to poor clinical outcome. This case, a 68-year-old woman with a history of type 2 diabetes mellitus (DM), hypothyroidism, bicuspid aortic valve and severe aortic stenosis, bronchial asthma, who had repeatedly refused any suggestion for open heart surgery, was our volunteer candidate for TAVR. After successful TAVR the peak pressure gradient decreased from 100mmHg to 17mmHg. So, TAVR could be a viable option for highly selected patients with severe aortic stenosis and bicuspid aortic valve who have favourable anatomy.

Abstract
Background and aims The key interest of this research is to identify the causes of the ongoing increasing trends in caesarean section or C-section (CS) deliveries in both urban and rural areas of Bangladesh. Methods This study analyzed all Bangladesh Demographic and Health Survey (BDHS) datasets through Chi-square and z tests and the multivariable logistic regression model. Results CS deliveries were found to be more prevalent in urban than in rural areas of Bangladesh. Mothers above 19 years, above 16 years at first birth, overweight mothers, those with higher educational levels, those who received more than one antenatal care (ANC) visit, fathers having secondary/higher education degrees and employed as workers or in business, and mothers living in wealthy households in the cities of Dhaka, Khulna, Mymensingh, Rajshahi, and Rangpur divisions had a significantly higher likelihood of CS deliveries in urban areas. Contrastingly, mothers with ages between 20 and 39 years, above 20 years at first birth, normal weight/overweight mothers, those with primary to higher level of education, those in the business profession, fathers who also received primary to higher education, mothers who received more than one ANC visit, and those living in wealthy households in Dhaka, Khulna, Mymensingh, Rajshahi, and Rangpur divisions were more likely to have CS deliveries in rural areas. The 45-49 age group mothers had a five times higher likelihood of CS deliveries [odds ratio (OR): 5.39] in urban areas than in rural areas. Wealthy mothers were more likely to be CS-delivered in urban (OR: 4.84) than in rural areas (OR: 3.67). Conclusion The findings reveal a gradual upward alarming trend in CS deliveries with an unequal contribution of significant determinants in urban and rural areas of Bangladesh. Therefore, integrated community-level awareness programs are an urgent need in accordance with the findings on the risks of CS and the benefits of vaginal deliveries in this country.

Abstract
The presence of conduction defects complicating acute myocardial infarction (MI) is relatively frequent and is associated with increased short and long term mortality. Thrombolytic therapy has been established to reduce the mortality in acute MI, however its role in reducing the incidence of conduction defects is less clearly defined. Morbidity and mortality associated with conduction defects also remain unchanged. This study was aimed to assess the correlation between conduction defects and adverse in-hospital outcome of patients with acute ST segment elevation MI. This cross sectional descriptive type of observational study was conducted among 100 purposively selected patients with acute ST segment elevation MI in the coronary care unit (CCU) of Mymensingh Medical College Hospital, Bangladesh from June 2012 to March 2013. The patients were divided into two groups depending on the presence or absence of conduction defects namely Group A- 40 patients with conduction defects and Group B- 60 patients without conduction defects. Highest number of the patients (36.0%) was in the age group of 45-55 years. In case of inferior MI, age groups 45-55 years and 55-65 years had equal number of patients (30.4%). Only 2.0% patients were in age group of 75-85 years and this group had only inferior MI. Total number of female patients were 16(16.0%). Female patients had more inferior MI (17.4%) than anterior MI (15.9%). Number of MI patients was slightly more in inferior MI (46.0%) than anterior MI (44.0%). Group B had equal number of patients in both anterior and inferior MI. Conduction defects were more common in inferior MI (43.5%) than anterior MI (40.9%). Atrio-ventricular conduction defects were more common in inferior MI whereas intra-ventricular conduction defects were more common in anterior MI. Complete heart block (CHB) was more prevalent in inferior MI. Complications were more common in Group A (65.0%) than Group B (18.3%). In terms of complications the difference between two groups were significant (p<0.001). Group A showed higher rate of mortality (20.0%) than Group B (3.3%). In cases of anterior MI difference in mortality between Group A and Group B was highly significant (p<0.001). Conduction defects in the setting of acute MI are a common finding. Atrio-ventricular conduction defects occur more frequently in inferior MI whereas intra-ventricular conduction defects were more frequently encountered in anterior MI. Patients with conduction defects had more complications than those without conduction defects. Presence of conduction defects significantly increases the mortality of patients with anterior MI.

Abstract
To compare the outcome of the laparoscopic totally extra peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia. This study was conducted as a prospective comparative (Quasi experimental) study from January 2010 to December 2010 at Combined Military Hospital (CMH), Dhaka, Bangladesh. A total of 100 male patients aged 24 to 70 years who underwent laparoscopic totally extra-peritoneal (Lap TEP) and open Lichtenstein tension free mesh repair (OLMR) of inguinal hernia were included in this study. Data of operating time, intraoperative and short-term postoperative complications, postoperative pain, postoperative hospital stay and return to normal activity were recorded and analyzed with SPSS program. Mean age of the patients was 51.39±15.099 years in OLMR group (Group A) and 47.10±9.338 years in Lap TEP group (Group B). Mean operating time was longer in Laparoscopic TEP group (Group B, 57.67±6.915 minutes) then open Lichtenstein mesh repair group (Group A, 50.56±6.292 minutes). Patient in the Lap TEP group (Group B) experienced less post operative pain, less post operative complications, shorter hospital stay and early return to normal activity then OLMR group (Group A). One patient (3.33%) in group B needed conversion to open Lichtenstein method. Two (6.66%) patients developed pneumoperitoneum in Group B (Lap TEP repair). Superficial wound infection developed in five (7.14%) patients in OLMR group (Group A) and two (6.66%) patients in Lap TEP group (Group B). In Laparoscopic TEP group (Group B) and Lichtenstein group (Group A), patients return to normal activity within on an average 07 and 11 days respectively. Laparoscopic totally extra peritoneal (TEP) mesh repair technique was associated with less post operative pain, less post operative complications, shorter hospital stay, faster recovery with early return to normal activity compared with Lichtenstein tension free mesh repair of inguinal hernia.

Abstract
A study was undertaken to determine the contents of trace metals in 60 topsoils and 80 brinjal fruits samples from a famous brinjal-producing area of Bangladesh using atomic absorption spectrophotometer. The study also looked at soil pollution levels, dietary intake of nutritionally important trace elements, and human health risks from toxic metals induced by dermal soil exposure and consumption of brinjal. The content of Pb, Ni, Cd, Cu, Fe, Mn, and Zn in brinjal fruits harvested from farmer′s fields ranged from 0.204–0.729, 0.031–0.212, < 0.010–0.061, 1.819–2.668, 3.267–5.910, < 0.010–0.866 and 2.160–3.846 µg g-1, respectively, while the amount of Cr was negligible. The calculated enrichment factors showed that 70, 50, and 25% of soil sampling sites had values in the 2.00–5.00 range for Pb, Zn, and Cd, respectively, while 30% of sites had values > 5.00 for Cd, indicating moderate to significant enrichment of these metals in the soil. The study also revealed that brinjal consumption provides a tiny amount of nutritionally important trace elements required for an adult human. Regarding the computed incremental lifetime cancer risks (ILCR), the study revealed that the values for Pb and Ni in all samples and Cd in 40% of samples were several hundred times higher for males and females than the USEPA threshold level due to oral ingestion of brinjal fruits. In contrast, dermal exposures to soil trace elements were within an acceptable range. The PCA results revealed that the contents of Cd, Pb, Ni, and Cu in soils showed strong positive correlations with those elements present in brinjal. The current study suggests future traceability research, focusing on pinpointing potential entry routes for toxic elements into the vegetable food chain.

Abstract
Digital technologies are the need of today to predict, prevent and control emerging infectious diseases. Bangladesh is one of the world's poorest and most densely populated countries and faces a double burden of two deadly diseases, COVID-19 and dengue. In response to both these diseases, the absence of a digital healthcare system and insufficient preparedness, lack of public awareness pose unique challenges and a large threat to the population, resulting in epidemics of escalating severity. This paper suggests a digital health care and surveillance system based on the internet of things (IoT) and artificial intelligence (AI) for timely identification of COVID-19 and dengue cases and improving the prevention and control strategies in the country. Digital technologies enable smart healthcare solutions to sustain and improve health services. Bangladesh is vulnerable to both COVID-19 and dengue epidemics. Epidemic preparedness requires improved digital health policy by integrating AI-IoT based emerging technologies. Campaigning to raise awareness of COVID-19 and dengue infections is a public health urgency.

Abstract
Different studies worldwide showed that dyslipidaemia is involved in the pathogenesis of ischemic heart diseases (IHD). This cross sectional descriptive type of observational study was carried out at Mymensingh Medical College Hospital during the period of six months from January 2021 to September 2021 to estimate the lipid profile among patients admitted in the coronary care unit (CCU) with myocardial infarction (MI). Data were collected from purposively selected 343 patients with MI by face to face interview and laboratory investigations using a case record form. Informed written consent of participants was taken prior to interview. Data were analyzed by using SPSS version 21.0. The study results revealed that mean age of the patients with myocardial infarction was 53.16 years with a standard deviation of 11.68 years. Majority of them (284, 82.8%) were male and the remaining (59, 17.2%) were female. Proportion of risk factors for ischaemic heart disease (IHD) were estimated and found that 244(71.1%) patients were smoker; 150(43.7%) had hypertension and 110(32.2%) had family history of IHD. Ninety nine (28.9%) patents were obese with BMI ≥25kg/m². Eighty three (24.2%) patients had diabetes mellitus; 66(19.2%) lead sedentary life and 61(17.8%) patients with myocardial infarction had dyslipidaemia. Mean LDL of patients with myocardial infarction was 103.65±39.73mg/dl; mean total cholesterol (TC) was 189.44±45.41mg/dl; mean TG was 243.11±205.19mg/dl and mean HDL was 39.29±8.98mg/dl. LDL was increased in 10(2.9%) patients; total cholesterol was raised in 121 (35.3%) patients and TG was raised in 195(56.9%) patients. HDL was raised in 26(7.6%) patients and it was lowered in 57(16.6%) patients. Mean LDL, TC, TG and HDL of younger (≤45 years) and older (>45 years) patients were compared and t-test showed no significant difference (p>0.05). Similarly mean LDL, TC, TG and HDL of male and female were compared and again t-test showed no significant difference (p>0.05). Though the pattern of lipid profile was found similar in younger and older patients and in males and females, a significant number of patients (61, 17.8%) with MI had dyslipidaemia which should be address by dietary and lifestyle modification.

Abstract
The study was aimed to assess the psychological aspects and relevant factors of the health-care workers (HCWs) working in COVID 19 pandemic condition in Bangladesh. This online cross-sectional survey was conducted from different tertiary, secondary and primary hospitals in Bangladesh. Eligible 638 HCWs who were directly involved in the caring of confirmed or suspected COVID-19 patients were recruited in this study. The mental health was assessed by the Patient Health Questionnare-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7) and Athens Insomnia Scale (AIS). High frequency of depression 536(84.0%), anxiety 386(60.5%) and insomnia 302(47.3%) was found among the HCWs, which were significantly higher in physicians (p<0.001) than nurses. Moderate to severe depression was significantly higher in female, whereas minimal to mild depression was significant in male HCWs (p=0.014). Symptoms of depression (p<0.001), anxiety (p<0.001) and insomnia (p=0.004) were significantly higher among the HCWs of primary and secondary compared to the tertiary level. The HCWs developed psychological trauma due to family health (45.3%) and contagious disease property (66.6%). After adjusting confounders, multivariable logistic regression analysis showed that physicians and HCWs of secondary hospital had significant symptoms of severe depression (OR=2.95, 95% CI=0.50-17.24; p<0.001), anxiety (OR=2.64, 95% CI=0.80-8.72; p<0.001) and insomnia (OR=2.67, 95% CI=1.23-5.84; p=0.018); whereas female HCWs had more risk of developing symptoms of severe insomnia (OR= 1.84; 95% CI=1.23-2.75; p=0.003). High rate of depression, anxiety and insomnia was found among HCWs working in the COVID-19 pandemic condition in this survey.

Abstract
BACKGROUND : TB was the leading cause of death from a single infectious pathogen globally between 2014 and 2019. Fine-scale estimates of TB prevalence and case notifications can be combined to guide priority-setting for strengthening routine surveillance activities in high-burden countries. We produce policy-relevant estimates of the TB epidemic at the second administrative unit in Bangladesh. METHODS : We used a Bayesian spatial framework and the cross-sectional National TB Prevalence Survey from 2015–2016 in Bangladesh to estimate prevalence by district. We used case notifications to calculate prevalence-to-notification ratio, a key metric of under-diagnosis and under-reporting. RESULTS : TB prevalence rates were highest in the north-eastern districts and ranged from 160 cases per 100,000 (95% uncertainty interval [UI] 80–310) in Jashore to 840 (UI 690–1020) in Sunamganj. Despite moderate prevalence rates, the Rajshahi and Dhaka Divisions presented the highest prevalence-to-notification ratios due to low case notifications. Resolving subnational disparities in case detection could lead to 26,500 additional TB cases (UI 8,500–79,400) notified every year. CONCLUSION : This study is the first to produce and map subnational estimates of TB prevalence and prevalence-to-notification ratios, which are essential to target prevention and treatment efforts in high-burden settings. Reaching TB cases currently missing from care will be key to ending the TB epidemic.

Abstract
Coronary artery disease (CAD) is the leading cause of death in developed and developing countries. Associated co-morbidities like diabetes, hypertension and obesity are making the situation worse. WHO enlisted obesity as an epidemic which also affects a great number of young population. Some recent studies showed the presence of an apparent paradoxical relationship between obesity and cardiovascular prognosis in certain subsets of patents. As BMI is an established marker of obesity; an attempt has been made to assess relationship between BMI and angiographic severity of coronary artery disease in Acute Coronary Syndrome (ACS) patients of Bangladeshi origin. To assess the association between body mass index and angiographic severity of coronary artery disease in patients with acute coronary syndrome; this cross sectional analytical study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital (MMCH) and Bangabandhu Sheikh Mujib Medical University (BSMMU) from December 2016 to February 2018 among purposively selected 65 patients. Relevant ethical issues were taken into consideration. Coronary angiogram was done in the same index hospitalization period. After coronary angiogram performed patients were grouped into two groups according to their BMI. Patients with BMI <25kg/m² as Group I and those ≥25kg/m² as Group II. Angiographic severity of coronary artery disease was assessed by vessel score and Syntax score. Mean age of Group I was 54.45±10.42 years, while in Group II it was 50.76±8.89 years reflecting the early presentation of higher BMI patients. Male to female ratio was 12:1. Mean BMI of Group I and Group II was 22.56±1.59 and 28.67±2.64 respectively. In Group I, 10(25.0%) had single vessel lesion, 15(37.5%) had double vessel lesion and 14(35.0%) had triple vessel lesion, while in Group II, 6(24.0%) had single vessel lesion, 12(48.0%) had double vessel lesion and 5(20.0%) had triple vessel lesion. Mean Syntax score of Group I and Group II was 13.18±8.45 and 10.42±7.14 respectively. Patients in the increasing BMI class had a higher prevalence of diabetes, hypertension and dyslipidaemia. A negative correlation was observed between BMI and angiographic severity (Vessel score, Syntax score and HRCA e.g. LM disease) of CAD indicating that patients with higher BMI had a lower coronary artery disease (CAD) severity than their normal BMI counterparts. Patients with high BMI have a lower CAD severity than usually expected. After adjustment for co-morbidities, BMI was not found as an independent predictor of severity of coronary artery disease.

Abstract
Combining ability analysis provides useful information for the selection of parents, also information regarding the nature and magnitude of involved gene actions. Crops improvement involves strategies for enhancing yield potentiality and quality components. Targeting the improvement of respective characters in bitter gourd, combining ability and genetic parameters for 19 characters were estimated from a 6×6 full diallel analysis technique. The results revealed that the variances due to general combining ability (GCA) and specific combining ability (SCA) were highly significant for most of the important characters. It indicated the importance of both additive and non-additive gene actions. GCA variances were higher in magnitude than SCA variances for all the characters studied indicating the predominance of the additive gene effects in their inheritance. The parent P2 (BG 009) appeared as the best general combiner for earliness; P1 (BG 006) for number of fruits, average single fruit weight and fruit yield; P4 (BG 027) for node number of first female flower and days to seed fruit maturity; P3 (BG 011) for fruit length and thickness of the fruit flesh; P5 (BG 033) for 100-seed weight; and P6 for number of nodes per main vine. The SCA effect as well as reciprocal effect was also significant for most of the important characters in different crosses.

Abstract
Atherosclerosis is the pathognomic sign of ischaemic heart disease. Inflammation of the coronary artery contributes to the development of atherosclerosis. Neutrophil-to-lymphocyte ratio (NLR) has been reported to predict the risk of CAD and associated events in patients with ST-Segment elevation myocardial infarction (STEMI). This study was done to investigate the role of neutrophil-to-lymphocyte ratio (NLR) in predicting in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase (STK). This cross sectional descriptive type of study was conducted in the Department of Cardiology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from August, 2017 to October, 2018. The STEMI patients, thrombolysed with STK had blood samples at admission, analyzed for complete blood counts and NLR calculated. They were grouped into two, low and high NLR, taking 4.50 as cut-off value. Chi square test was used to compare rate of adverse events and death in hospital stay. Logistic regression analysis was used to estimate predictive ability of NLR for in-hospital cardiac events. A total of 87 (39.90%) patients had complications. Patients in high NLR group had higher rate of complications (48.3% vs. 22.5%, p<0.001) in hospital than those in low NLR group. Arrhythmias (21.1% vs. 9.9%, p<0.041), heart failure (27.9% vs. 14.1%, p=0.024), cardiogenic shock (16.3% vs. 4.2%, p<0.011), death (6.8% vs. 2.8%, p=0.227), re-infarction /post MI angina (4.1% vs. 0.0% p=0.084) occurred more in high NLR group. Mean NLR was significantly different between Group I and Group II (3.11±0.84 vs. 10.20±6.08, p<0.0001). Multivariate regression analysis showed NLR an independent predictor of in-hospital adverse cardiac events (p<0.0001). High on admission NLR is an independent predictor for in-hospital adverse cardiac events in patients with STEMI thrombolysed with streptokinase.

Abstract
BACKGROUND Bangladesh is a densely populated country with a substandard healthcare system and a mediocre economic framework. Due to the enormous number of people who have been unaware until now, the development of COVID-19's second-wave infection has become a severe threat. The present investigation aimed to characterize the clinical and socio-demographic characteristics of COVID-19 in Bangladesh. METHODS A cross-sectional analysis was carried out from all the other COVID-19 patients and confirmed by RT-PCR undergoing a specialized COVID-19 hospital. From March 1 to April 15, 2021, a total of 1326 samples were collected. Samples were only obtained from non-critical COVID-19 patients as critically ill patients required emergency intensive care medications. Then, from April 17 to May 03, 2021, SARS-CoV-2 infection and clinical assessment was performed based on interim guidelines from the WHO. The diagnosis was conducted through RT-PCR. Later, identifying the symptomatic and asymptomatic patient based on checking the Clinical Observation Form (COF). The patients filled the COF form. Finally, statistical analyses were done using the SPSS 20 statistical program. RESULTS In this investigation, a total of 326 patients were diagnosed as COVID-19 positive. Among them, approximately 19.02% (n = 62) were asymptomatic, and 80.98% (n = 264) were symptomatic. Here, the finding shows that the occurrence of this infection was varied depending on age, sex, residence, occupation, smoking habit, comorbidities, etc. However, Males (60.12%) were more affected than females (39.88%), and, surprisingly, this pandemic infected both urban and rural residents almost equally (urban = 50.92%; rural = 49.08%). Approximately 19% of the asymptomatic and 62% of symptomatic cases had at least one comorbid disorder. Interestingly, an unexpected result was exhibited in the case of smokers, where non-smokers were more affected than smokers. The study indicates community transmission of COVID 19, where people were highly infected at their occupations (35.58%), at houses (23.93%) and by traveling (12.88%). Noteworthy, according to this report, a large number (19.33%) of individuals did not know exactly how they were contaminated with SARS-CoV-2. Patients were most commonly treated by an antibiotic 95.09%, followed in second by corticosteroid 46.01%. Anti-viral drugs, remdesivir, and oxygenation are also needed for other patients. Among those, who were being treated, approximately 69.33% were isolated at home, 27.91% were being treated at dedicated COVID-19 hospitals. Finally, 96.63% were discharged without complications, and 0.03% has died. CONCLUSION This investigation concludes that males became more infected than females. Interestingly, both urban and rural people became nearly equally infected. It noticed community transmission of SARS-CoV-2, where people were highly infected at their workplaces. A higher rate of silent transmission indicates that more caution is needed to identify asymptomatic patients. Most of the infected people were isolated at home whereas nearly one-fourth were treated at hospitals. Clinically, antibiotics were the most widely used treatment. However, the majority of the patients were discharged without complications. The current investigation would be helpful to understand the clinical manifestations and socio-demographic situations during the second wave of the COVID-19 pandemic in Bangladesh.

Abstract
Complete assessment of obstructive jaundice requires the use of various imaging modalities that are required to detect the cause and level of obstruction thus helping in treatment planning. Magnetic Resonance Cholangio Pancreatography (MRCP) is a current available technology which is a non-invasive technique that visualizes the gallbladder, biliary tree and pancreatic duct and also provides information about surrounding structures. This study was done to correlate the MRCP findings with post-operative result and thereby demonstrate the specificity, sensitivity and efficacy of MRCP as an accurate investigatory tool for biliary obstruction. Total of fifty (50) patients of clinically diagnosed obstructive jaundice were studied from March 2017 to August 2017 in the Department of Radiology and Imaging, Combined Military Hospital, Dhaka, Bangladesh. In all these cases, USG was the initial screening investigation followed by MRCP. Cause and level of obstruction were evaluated using MRCP findings. MRCP results were correlated with surgical findings and few cases also with direct ERCP findings. Statistical analysis was done to see the sensitivity, specificity, accuracy, positive and negative predictive values of MRCP in diagnosis of biliary obstruction. In this study, USG detected level of obstruction in 56% (28 out of 50) cases. USG could detect causes of obstruction in 100% (02 out of 02) cases of choledocal cyst and 66.67% (02 out of 03) benign stricture, 60% (03 out of 05) cases of periampullary carcinoma, 57.70% (06 out of 14) cases of choledocholithiasis, and 42.86% (15 out of 26) cases of cholangiocarcinoma. On the other hand, MRCP detected level of obstruction in 98% (49 out of 50) cases. MRCP could detect causes of obstruction in 100% cases of cholangiocarcinoma, choledocholithiasis, benign stricture and choledocal cyst and 80% (04 out of 05) cases of periampullary carcinoma. In this study, ERCP could detect causes of obstruction in 32 cases of choledocholithiasis and benign stricture, but in case of cholangiocarcinoma ERCP was failed in 3 cases. In this study, for detection of cause of obstruction, ERCP had the highest sensitivity (97.79%); followed by MRCP (96.65%) and USG (60.25%). The overall diagnostic accuracy for detection of cause of obstruction was the highest for ERCP (95.50%); followed by MRCP (94.50%) and USG (64.50%). MRCP can be done in a short duration and is a noninvasive diagnostic modality compared to ERCP. MRCP needs to be advocated as a viable and non-invasive alternative with compararable sensitivity and specificity to ERCP.

Abstract
Climate change-induced salinity intrusion into agricultural soils is known to negatively impact crop production and food security. However, the effects of salinity increase on plant-herbivore-natural enemy systems and repercussions for pest suppression services are largely unknown. Here, we examine the effects of increased salinity on communities of rice (Oryza sativa), brown planthopper (BPH), Nilaparvata lugens, and green mirid bug (GMB), Cyrtorhinus lividipennis, under greenhouse conditions. We found that elevated salinity significantly suppressed the growth of two rice cultivars. Meanwhile, BPH population size also generally decreased due to poor host plant quality induced by elevated salinity. The highest BPH density occurred at 2.0 dS/m salinity and declined thereafter with increasing salinity, irrespective of rice cultivar. The highest population density of GMB also occurred under control conditions and decreased significantly with increasing salinity. Higher salinity directly affected the rice crop by reducing plant quality measured with reference to biomass production and plant height, whereas inducing population developmental asynchrony between BPH and GMB observed at 2 dS/m salinity and potentially uncoupling prey-predator dynamics. Our results suggest that increased salinity has harmful effects on plants, herbivores, natural enemies, as well as plant-pest-predator interactions. The effects measured here suggest that the bottom-up effects of predatory insects on rice pests will likely decline in rice produced in coastal areas where salinity intrusion is common. Our findings indicate that elevated salinity influences tritrophic interactions in rice production landscapes, and further research should address resilient rice insect pest management combining multipests and predators in a changing environment.

Abstract
BACKGROUND Bangladesh experienced its worst dengue fever (DF) outbreak in 2019. This study investigated the knowledge, attitudes and practices (KAP) among university students in Bangladesh and significant factors associated with their prevention practices related to climate change and DF. METHODS A social media-based (Facebook) cross-sectional KAP survey was conducted and secondary data of reported DF cases in 2019 extracted. Logistic regression and spatial analysis were run to examine the data. RESULTS Of 1500 respondents, 76% believed that climate change can affect DF transmission. However, participants reported good climate change knowledge (76.7%), attitudes (87.9%) and practices (39.1%). The corresponding figures for DF were knowledge (47.9%), attitudes (80.3%) and practices (25.9%). Good knowledge and attitudes were significantly associated with good climate change adaptation or mitigation practices (p<0.05). Good knowledge, attitudes and previous DF experiences were also found to be significantly associated with good DF prevention practices (p<0.001). There was no significant positive correlation between climate change and DF KAP scores and the number of DF cases. CONCLUSIONS Findings from this study provide baseline data that can be used to promote educational campaigns and intervention programs focusing on climate change adaptation and mitigation and effective DF prevention strategies among various communities in Bangladesh and similar dengue-endemic countries.

Abstract
BACKGROUND Dengue is linked with climate change in tropical and sub-tropical countries including the Lao People's Democratic Republic (Laos) and Thailand. Knowledge about these issues and preventive measures can affect the incidence and outbreak risk of dengue. Therefore, the present study was conducted to determine the knowledge, attitudes, and practices (KAP) among urban and rural communities and government officials about climate change and dengue in Laos and Thailand. METHODS A cross-sectional KAP survey about climate change and dengue were conducted in 360 households in Laos (180 urban and 180 rural), 359 households in Thailand (179 urban and 180 rural), and 20 government officials (10 in each country) using structured questionnaires. Data analysis was undertaken using descriptive methods, principal component analysis (PCA), Chi-square test or Fisher's exact test (as appropriate), and logistic regression. RESULTS Significant differences among the selected communities in both countries were found in terms of household participant's age, level of education, socioeconomic status, attitude level of climate change and KAP level of dengue (P < 0.05; 95% CI). Overall, participants' KAP about climate change and dengue were low except the attitude level for dengue in both countries. The level of awareness among government officials regarding the climatic relationship with dengue was also low. In Lao households, participants' knowledge about climate change and dengue was significantly associated with the level of education and socioeconomic status (SES) (P < 0.01). Their attitudes towards climate change and dengue were associated with educational level and internet use (P < 0.05). Householders' climate change related practices were associated with SES (P < 0.01) and dengue related practices were associated with educational level, SES, previous dengue experience and internet use (P < 0.01). In Thailand, participants' knowledge about climate change was associated with the level of education and SES (P < 0.01). Their attitudes towards climate change were associated with residence status (urban/rural) and internet use (P < 0.05); climate change related practices were associated with educational level and SES (P < 0.05). Dengue related knowledge of participants was associated with SES and previous dengue experience (P < 0.05); participants' dengue related attitudes and practices were associated with educational level (P < 0.01). CONCLUSION The findings call for urgently needed integrated awareness programs to increase KAP levels regarding climate change adaptation, mitigation and dengue prevention to improve the health and welfare of people in these two countries, and similar dengue-endemic countries.

Abstract
Myositis ossificans (MO) is a condition where calcification occurs in the soft tissue as well as around the bone following fracture, vigorous exercise or trauma. Although it is a radiological diagnosis, it often leads physician to an incorrect or missed diagnosis as recurrent fracture. Frequently, it follows haemorrhage into the muscle in the tissue space. We report a 45 years old house-wife presented with the complaints of weakness of right side of body and pain with restricted range of motion (ROM) in right lower limb. She was a diagnosed case of recurrent stroke with rheumatic valvular heart disease. After discharge, vigorous physical exercise was done at home by local physiotherapist without appropriate guidance from physiatrist. Gradually pain was so severe that she didn't allow moving her right lower limb. Over the course of time, she became incapacite and bed bound. She denied any positive family history. With the hip and lower limb problems she consulted with orthopedic surgeon and was referred to Physical Medicine and Rehabilitation department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh for further management & rehabilitation. This case is presented to focus on hazard of being unguided, over-exercised and non-surgical management approach of this rare condition.

Abstract
Patients with Diabetes Mellitus are at high risk of cardiovascular events because of abnormal lipid metabolism. Dyslipidemia is common in patients with Diabetes Mellitus (DM). However; in Bangladesh this issue is not yet properly addressed. The aim of this study is to determine the prevalence and patterns of dyslipidaemia in patients with DM in a divisional city Mymensingh. This cross-sectional study was conducted in randomly selected eligible patients from the indoor registry of the Department of Cardiology, Mymensingh Medical College Hospital (MMCH), Bangladesh from April 2012 to March 2013. A well structured questionnaire and blood investigation for lipid profile and blood sugar were the tools of data collection from 120 randomly selected DM patients registered in the department of cardiology, MMCH. Out of 120 enrolled participants the prevalence of dyslipidemia in DM patients was 86.0%, prevalence of dyslipidemia in males was 88.0% while in females was 85.0% but the difference was not significant (p=0.42). Regarding age group, BMI and duration of DM, there is no significant association exists with dyslipidemia. About half of the studied DM patients have high serum total cholesterol level (50.83%), while 22.5% had low serum HDL-C levels and 35.0% had high serum LDC-C level, most of patients had serum triglyceride levels above normal range (67.5%) and so the common patterns of dyslipidemia in this study were serum triglyceride level followed by total cholesterol. High prevalence of dyslipidemia among diabetes mellitus in Mymensingh city were observed and so the common patterns of dyslipidemia is triglyceride followed by total cholesterol. This study emphasizes the importance of screening of lipid profile as these abnormalities may lead to development of cardiovascular diseases.

Abstract
As other nations around the world, Bangladesh is facing enormous challenges with the novel coronavirus (COVID-19) epidemic. To design a prevention and control strategy for this new infectious disease, it is essential to first understand people's knowledge, attitudes, and practices (KAP) regarding COVID-19. This study sought to determine KAP among rural and urban residents as well as predictors of preventive practices associated with COVID-19 in Bangladesh. A social media-based (Facebook) cross-sectional survey was conducted to explore these variables among Bangladeshi adults. Of 1520 respondents who completed the questionnaire, low level of good or sufficient knowledge of COVID-19 (70.8%) and practices associated with COVID-19 (73.8%) were found. Despite the low level of knowledge and practices, respondents' attitude (78.9%) towards COVID-19 was relatively high. Results suggest that compared to urban, rural residents are at a particularly high risk of COVID-19 because they were found to have significantly lower knowledge (p = 0.001) and practice levels (p = 0.002) than were urban residents. Multivariable logistic regression analysis identified gender, education, knowledge of COVID-19 transmission, signs and symptoms, and sources of information as factors significantly associated with preventive practices against COVID-19. Further attention and effort should be directed toward increasing both knowledge and practices targeting the general population in Bangladesh, particularly the rural and less educated residents. Findings from this study provide baseline data that can be used to promote integrated awareness of and effective health education programs about COVID-19 prevention and control strategies in Bangladesh, and similar COVID-19 endemic countries.

Abstract
This study describes the molecular detection of human brucellosis among patients with pyrexia of unknown origin. It was a cross-sectional descriptive study and was carried out in the Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh. Non-probability purposive type of sampling technique was used. Blood samples were collected from 400 pyretic patients from September 2018 to August 2019. BCSP31 Brucella genus-specific TaqMan real-time PCR and SYBR Green real-time PCR were undertaken for molecular detection. Out of 400 samples, 22 (5.5%) samples found BCSP31 Brucella genus-specific real-time PCR positive. The study revealed that a considerable number of brucellosis is present in rural areas among risk as well as non-risk group study population having definite male predominancy, most prone to develop among >40-80 years age group. Brucella genus and species-specific real-time PCR might be performed for confirmation and also to avoid unjustified costs, drug toxicity, and un-masking of other potentially dangerous diseases.

Abstract
It has been widely reported that vitamin D deficiency is associated with Coronary heart disease (CHD), especially acute Myocardial infarction (MI). Many factors are responsible for reduced Left ventricular ejection fraction (LVEF) and acute Left ventricular fraction (LVF) after acute MI. This cross sectional descriptive type of study was conducted in the Cardiology department of Mymensingh Medical College Hospital from October 2017 to March 2019 to investigate the relationship of plasma vitamin D with LVEF in patients with first attack of acute MI. Total 185 patients of first attack of acute MI were included considering inclusion and exclusion criteria. Fasting blood samples were analyzed for plasma vitamin D level. Sample population were grouped at first into two, normal and low vitamin D level, taking 30ng/ml as cut-off value, low vitamin D level is further subdivided into insufficiency (21-29ng/ml), deficiency (10-20ng/ml) and severe deficiency (<10ng/ml). LVEF among the patients was observed. LVEF was found 49.88±8.58% patients having normal vitamin D level (>30ng/ml), 47.60±8.24% of patients having vitamin D insufficiency (21-29ng/ml), 44.38±8.12% of patients having vitamin D deficiency (10-20ng/ml) and 40.61±8.64% patients having severe vitamin D deficiency (<10ng/ml), which was statistically significant (p<0.05). So, low plasma vitamin D level is associated with reduced LVEF in patients hospitalized with first attack of acute MI.

Abstract
Objectives To provide an overview of the three major deadly coronaviruses and identify areas for improvement of future preparedness plans, as well as provide a critical assessment of the risk factors and actionable items for stopping their spread, utilizing lessons learned from the first two deadly coronavirus outbreaks, as well as initial reports from the current novel coronavirus (COVID-19) epidemic in Wuhan, China. Methods Utilizing the Centers for Disease Control and Prevention (CDC, USA) website, and a comprehensive review of PubMed literature, we obtained information regarding clinical signs and symptoms, treatment and diagnosis, transmission methods, protection methods and risk factors for Middle East Respiratory Syndrome (MERS), Severe Acute Respiratory Syndrome (SARS) and COVID-19. Comparisons between the viruses were made. Results Inadequate risk assessment regarding the urgency of the situation, and limited reporting on the virus within China has, in part, led to the rapid spread of COVID-19 throughout mainland China and into proximal and distant countries. Compared with SARS and MERS, COVID-19 has spread more rapidly, due in part to increased globalization and the focus of the epidemic. Wuhan, China is a large hub connecting the North, South, East and West of China via railways and a major international airport. The availability of connecting flights, the timing of the outbreak during the Chinese (Lunar) New Year, and the massive rail transit hub located in Wuhan has enabled the virus to perforate throughout China, and eventually, globally. Conclusions We conclude that we did not learn from the two prior epidemics of coronavirus and were ill-prepared to deal with the challenges the COVID-19 epidemic has posed. Future research should attempt to address the uses and implications of internet of things (IoT) technologies for mapping the spread of infection.

Abstract
Excessive body fat and the related dysmetabolic diseases affect both developed and developing countries. The aim of this study was to investigate the beneficial role of a bacterial culture supernatant (hereafter: BS) of Lactobacillus and Bifidobacterium and their potential mechanisms of action on white-fat browning and lipolysis. For selection of four candidates among 55 Lactic acid producing bacteria (LAB) from human infant faeces, we evaluated by Oil Red O staining and Ucp1 mRNA quantitation in 3T3-L1 preadipocytes. The expression of browning and lipolysis markers was examined along with in vitro assays. The possible mechanism was revealed by molecular and biological experiments including inhibitor and small interfering RNA (siRNA) assays. In a mouse model, physiological, histological, and biochemical parameters and expression of some thermogenesis-related genes were compared among six experimental groups fed a high-fat diet and one normal-diet control group. The results allow us to speculate that BS treatment promotes browning and lipolysis both in vitro and in vivo. Moreover, the BS may activate thermogenic programs via a mechanism involving PKA-CREB signaling in 3T3-L1 cells. According to our data, we can propose that two LAB strains, Bifidobacterium longum DS0956 and Lactobacillus rhamnosus DS0508, may be good candidates for a dietary supplement against obesity and metabolic diseases; however, further research is required for the development as dietary supplements or drugs.

Abstract
Acute occlusive thrombosis of the coronary artery is the principal cause of myocardial infarction where platelets play an important role. Large size platelets, easily measured by mean platelets volume (MPV) are thrombogenic and commonly seen after ST-segment elevation myocardial infarction (STEMI). ST segment resolution has been shown as a simple non-invasive marker that reflects both epicardial and myocardial reperfusion following thrombolysis. The present study intended to investigate whether MPV on admission correlated with ST segment resolution following thrombolysis in STEMI patient. This cross-sectional analytical study was conducted in the department of cardiology, Mymensingh Medical College and Hospital (MMCH), Mymensingh, Bangladesh from December, 2016 to June, 2018. Total 284 patients with first attack of STEMI were included after considering inclusion and exclusion criteria. Sample population was divided into two groups, Group I - Patients with successful ST segment resolution (≥50%). Group II - Patients with impaired ST segment resolution (<50%). MPV on admission was estimated during estimation of Complete Blood Count (CBC) by Automated Haematology Analyzer & compared between two groups. Successful ST segment resolution (≥50%) was seen in 67% of patients after thrombolysis. Admission MPV was higher in patients with impaired ST segment resolution (<50%) group than patients with ≥50% ST-segment resolution group (12.42±0.89fl vs.10.35±0.77fl respectively, p=0.001). Statistically significant strong negative correlation between MPV and ST segment resolution percentage (r = -0.742, p=0.001) suggesting that the higher the level of MPV, the lower the ST segment resolution percentage in first attack of STEMI patients. Multivariate regression analysis found MPV level on admission as an independent predictor of ST segment resolution. The study concluded that high MPV on admission correlate with impaired ST segment resolution following thrombolysis in STEMI patients.

Abstract
OBJECTIVES To provide an overview of the three major deadly coronaviruses and identify areas for improvement of future preparedness plans, as well as provide a critical assessment of the risk factors and actionable items for stopping their spread, utilizing lessons learned from the first two deadly coronavirus outbreaks, as well as initial reports from the current novel coronavirus (COVID-19) epidemic in Wuhan, China. METHODS Utilizing the Centers for Disease Control and Prevention (CDC, USA) website, and a comprehensive review of PubMed literature, we obtained information regarding clinical signs and symptoms, treatment and diagnosis, transmission methods, protection methods and risk factors for Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS) and COVID-19. Comparisons between the viruses were made. RESULTS Inadequate risk assessment regarding the urgency of the situation, and limited reporting on the virus within China has, in part, led to the rapid spread of COVID-19 throughout mainland China and into proximal and distant countries. Compared with SARS and MERS, COVID-19 has spread more rapidly, due in part to increased globalization and the focus of the epidemic. Wuhan, China is a large hub connecting the North, South, East and West of China via railways and a major international airport. The availability of connecting flights, the timing of the outbreak during the Chinese (Lunar) New Year, and the massive rail transit hub located in Wuhan has enabled the virus to perforate throughout China, and eventually, globally. CONCLUSIONS We conclude that we did not learn from the two prior epidemics of coronavirus and were ill-prepared to deal with the challenges the COVID-19 epidemic has posed. Future research should attempt to address the uses and implications of internet of things (IoT) technologies for mapping the spread of infection.

Abstract
•IoT within infectious disease epidemiology is an emerging field of research, however the ubiquitous availability of smart technologies, as well as increased risks of infectious disease spread through the globalization and interconnectedness of the world necessitates its use for predicting, preventing and controlling emerging infectious diseases.•Considering the present situation in China, IoT based smart disease surveillance systems have the potential to be a major breakthrough in efforts to control the current pandemic. With much of the infrastructure itself in place already (i.e. smartphones, wearable technologies, internet access) the role this technology can have in limiting the spread of the pandemic involves only the collection and analysis of data already gathered.•More research must be carried out for the development of automated and effective alert systems to provide early and timely detection of outbreaks of such diseases in order to reduce morbidity mortality and prevent global spread.

Abstract
Coronary heart disease (CHD) is the most common cause of heart disease and serious cause of early death in developed countries around the world. Stress hyper-glycaemia has a bad prognostic implication in hospital outcomes in acute ST elevated myocardial infarction patients. It serves as a marker of myocardial damage, provides information about complications of acute MI and bad prognosis. The aim of this cross-sectional descriptive study was to find out prognostic implications of Stress hyper-glycaemia in non diabetic patients with first attack of acute ST elevated myocardial infarction underwent thrombolysis and conducted in the department of Cardiology in Mymensingh Medical College Hospital, Mymensingh, Bangladesh from June 2017 to May 2018. Total 249 first attack of Acute STEMI patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group I: Patients with first attack of acute STEMI underwent thrombolysis with non diabetic stress hyper-glycaemia (Blood sugar >7.8mmol/L and HbA1c <6.5), Group II: Patients with first attack of acute STEMI underwent thrombolysis with non diabetic normo-glycaemia (Blood sugar <7.8mmol/L and HbA1c <6.5). In this study, in non diabetic Stress hyperglycemic patients' death was 5.7% and in non diabetic normo-glycemic patients death was 0.6%. It was statistically significant (p<0.05). In non diabetic stress hyperglycemic patients, heart failure was 78.31% patients and in non diabetic normo-glycemic patients, it was 21.6%. It was statistically significant (p<0.01). Echocardiography showed that patients with non diabetic Stress hyper-glycaemia had mean ejection fraction (LVEF) was 44.01±4.93 and patients with non diabetic normo-glycaemia had mean ejection fraction (LVEF) was 47.70±5.71. It was statistically significant (p<0.01). In this study, in non diabetic Stress hyperglycaemic patients, cardiogenic shock was 16.1% and in non diabetic normo-glycemic patients, it was 3.7%. It was statistically significant (p<0.05). Mean duration of hospital stay, in non diabetic Stress hyperglycaemic patients was 5.07±0.566 and in non diabetic normo-glycemic patients, it was 3.52±0.850. It was statistically significant (p<0.001). In conclusion, the incidence of death, heart failure, cardiogenic shock and hospital stay were higher in non diabetic Stress hyperglycaemic patients than non diabetic normo-glycemic patients who admitted with first attack of acute ST elevated myocardial infarction.

Abstract
In this article, we revisit random site and bond percolation in a square lattice, focusing primarily on the behavior of entropy and the order parameter. In the case of traditional site percolation, we find that both the quantities are zero at p=0, revealing that the system is in the perfectly ordered and in the disordered state at the same time. Moreover, we find that entropy with 1-p, which is the equivalent counterpart of temperature, first increases and then decreases again, but we know that entropy with temperature cannot decrease. However, bond percolation does not suffer from either of these two problems. To overcome this, we propose an alternative definition for site percolation where we occupy sites to connect bonds and we measure cluster size by the number of bonds connected by occupied sites. This resolves all the problems without affecting any of the existing known results.

Abstract
A cross sectional descriptive study was performed on 40 postmortem vermiform appendix (male 24 and female 16) to find out the diameter of lymphoid follicle of vermiform appendix of Bangladeshi people. The specimens were collected from autopsy laboratory of the Department of Forensic Medicine, Mymensingh Medical College, Mymensingh, Bangladesh by purposive sampling technique and were divided into four age groups. They were Group A (upto 20 years), Group B (21 to 40 years), Group C (41 to 60 years) and Group D (above 60 years). For this purpose, about 3mm long of whole thickness transverse section was taken from the middle of the vermiform appendix and thus the permanent slides were made for microscopic examination. To measure the diameter of the lymphoid follicle two measurements were taken. One was taken at the maximum diameter and another was perpendicular to it by ocular micrometer. Diameter of one largest and one smallest lymphoid follicles were measured and find out the mean diameter of lymphoid follicle between them. Diameter of lymphoid follicle = (Maximum transverse diameter + perpendicular diameter) /2. All data were recorded in the predesigned data sheet, analyzed by SPSS program (version 21, 2012) and compared with the findings of other national and international studies and standard text books. It was observed that diameter of lymphoid follicle of vermiform appendix gradually decreased as age advanced. The mean±SD diameter of lymphoid follicle was 580.31±37.07, 545.58±38.37, 485.68±40.20 and 428.12±68.41μm in Group A, B, C and D respectively. Statistical analysis shows that the mean differences of diameter of lymphoid follicle between A&B, C&D were statistically non significant at p= or >0.05 level, difference between Group B&C was statistically moderately significant at p<0.01 level and differences between Group A&C, B&D, A&D were statistically highly significant at p<0.001 level. Mean diameter of lymphoid follicle of vermiform appendix in male was higher (584.30±12.65μm in Group A, 549.42±38.36μm in Group B, 487.38±39.91μm in Group C, 430.68±70.30μm in Group D) than in female (576.31±53.77μm in Group A, 536.61±45.14μm in Group B, 483.14±46.68μm in Group C, 424.28±75.95μm in Group D) but mean difference between sexes in the different groups was statistically non significant at p=or >0.05 level. The present study will help to increase the information pool on the diameter of lymphoid follicle of vermiform appendix of Bangladeshi people.

Abstract
Depression is a common comorbidity of type 2 diabetes mellitus (T2DM) which adversely affects diabetes management and outcome. Identifying and treating comorbid depression may improve diabetes care. This cross-sectional study was conducted in several tertiary hospitals throughout Bangladesh from July 2017 to April 2018. Nine hundred (900) adult patients with T2DM aging ≥25 years having diabetes for at least 6 months and equal numbers of non-diabetic otherwise healthy controls were recruited from the outpatient departments of these centers. Depression was assessed in all consenting patients and controls by administering the Bangla (local language) version of the PRIME-MD Patient Health Questionnaire (PHQ-9); participants obtaining a score of 5 or more were labeled to have depression. Depression was present in 60.3% of T2DM patients and in 29.4% of controls. Statistically significant difference was found in age, marital status, occupation, body mass index (BMI), waist circumference, systolic blood pressure (BP), diastolic BP and PHQ-9 score between diabetic and non-diabetic subjects (<0.001). T2DM subjects had 4.71-fold higher odds of depression in comparison to the controls (95% CI: 3.76-5.90; p<0.001). Age ≥50 years, unmarried status, years of schooling ≤10 years, underweight, abdominal obesity, and hypertension appeared to be the significant predictors of depression in the study subjects. In T2DM subjects, diabetes in the family members, the presence of other comorbidities, diabetic complications, diabetes duration >5 years, insulin use, using insulin syringe for injection, albuminuria and CKD were the important predictors of depression. Our study found higher prevalence and risk of depression in T2DM patients than their non-diabetic counterparts. T2DM patients should be screened for depression in order to achieve and maintain the treatment goals.

Abstract
Nasolacrimal duct obstruction due to chronic dacryocystitis is the most common cause of epiphora. Dacryocystorhinostomy (DCR) is the treatment of choice for chronic dacryocystitis. This can be carried out by external, endoscopic and endolaser surgical approach. Though external DCR is still a gold standard and most popular method, the latest procedure of less traumatic DCR is transcanalicular approach. The study was done to evaluate the outcome of Transcanalicular Endolaser DCR regarding epiphora and surgery related complications by measuring anatomical success rate (patency assessed by irrigation), functional success rate (symptom free) and complication rate and to compare with External DCR (Ext-DCR). This prospective interventional study was conducted from October 2011 to September 2012 in Ophthalmology department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Total 62 patients included in the study as per inclusion and exclusion criteria of them 31 for TCEL-DCR and 31 for Ext-DCR. But during follow-up one patient was dropped from each group and finally outcome of 30 patients analyzed in each group. Mean age of the patients TCEL-DCR was 38.3±11.54 and of Ext-DCR was 38.4±14.01. In both groups females were the most sufferer (female: male = 1.5: 1). Functional and anatomical success rate of TCEL-DCR showed 93.3% and 83.3% after 3 months; 83.3% and 76.7% after 6 months respectively. Statistically non-significant difference was observed about success rate in comparison between groups. Per-operative complications were pain excessive bleeding. In TCEL-DCR pain complained 13.3% and excessive bleeding occurred in 3.3%. Where as in Ext-DCR pain complained 16.7% and excessive bleeding occurred in 20%; difference was statistically significant (p=0.001). Post-operative complications were bleeding and scar formation. Bleeding occurred in TCEL-DCR 6.67% and in Ext-DCR 10%. So, TCEL-DCR could be an alternative option for the treatment of chronic dacryocystitis especially for those patients who are conscious about scar formation and afraid about Ext-DCR technique.

Abstract
Mastitis is a multifactorial and infectious disease of the udder of dairy animals. Infected animals suffer from pain and fever and causing damage in udder and changes in milk. The aim of this work was to determine the prevalence of clinical and sub-clinical caprine mastitis associated with bacterial pathogens during the period from January to June, 2017. A total of 120 lactating goats were randomly selected from different villages of Dinajpur district and 240 milk samples from each udder half were aseptically collected. The udders were examined and screened for the evidence of clinical and subclinical mastitis by clinical examination of udders and examining milk samples. Subclinical mastitis was detected by California Mastitis Test (CMT). Milk samples of all clinical and subclinical mastitis goats were cultured in/on bacteriological media for isolation and characterization of responsible bacterial pathogens. The overall prevalence of clinical and subclinical mastitis in goats was found to be 11.67% and 38.75%, respectively. Bacteriological examination of mastitic milk samples of caprine revealed Staphylococcus spp. (32.5%) as the major pathogen followed by Escherichia coli (22.5%), Pseudomonas spp. (12.5%), Klebsiella spp. (12.5%) and Bacillus spp. (5%). Results of this study indicated that about 50% of caprine udder were infected with mastitis (38.75%), which may render lowering milk production and mortality of goats and kids. It needs to screen milk sample of lactating goats by CMT, identify mastitic goats with infected bacteria, evaluate antibiotic sensitivity and design control strategy accordingly.Progressive Agriculture 29 (2): 127-138, 2018

Abstract
Enterocutaneous fistulae are a major catastrophe to the patients and surgeons and it still has high incidence of morbidity and mortality and their management remains a big challenge. Enterocutaneous fistula presents the surgeon with challenges of metabolic disorders and extensive sepsis. Total management of an intestinal fistula requires skill in nutritional support, stoma therapy, elimination of sepsis, well timed and well carried out surgery. Postoperative enterocutaneous fistulae account for approximately 80% of enterocutaneous fistulae. The majority of the intestinal fistula (75-85%) is iatrogenic occurring in the postoperative period following anastomotic dehiscence. They arise following emergency abdominal surgery for intestinal obstruction, inflammatory bowel disease or cancers. Protein calorie malnutrition alters the patients immune response, inflammatory reactions and tissue regenerations, all of which are essential for wound repair. The present study is an effort to highlight the incidence of enterocutaneous fistula after emergency and elective resection and anastomosis of gut with discussion over recent trends and developments in its management and compare with other studies. Objectives of the study are to determine the various clinicopathological features and management protocol of enterocutaneous fistula. There are recent advances in nutritional support. This descriptive type of cross-sectional study was carried out in the Department of Surgery, Mymensingh Medical College and Hospital, Mymensingh, Bangladesh from October 2010 to September 2011. Total 42 cases of enterocutaneous fistulae were selected purposively. Enterocutaneous fistulae are more common in patients of low economic condition. Enterocutaneous fistulae are more common after emergency abdominal surgery. Spontaneous closure occurred in 17(40.48%) cases and surgery needed in 25(59.52%) cases. Of them 20(80.00%) were healed and 5(20.00%) were expired. In spite of improvement in the management protocol of enterocutaneous fistula, there is still high unacceptable morbidity and mortality rate. Total parenteral nutrition (TPN) is not available and very costly, and health care facilities are also limited in our country. Patients with enterocutaneous fistula require fluid, electrolytes and nutritional support. Anaemia, dehydration, electrolytes imbalance should be corrected prior to abdominal surgery if possible. Surgical treatment for enterocutaneous fistula should be performed only after failure of conservative treatment of more than 12 weeks.

Abstract
Eclampsia is a common problem in pregnancy in Bangladesh. It is a severe form of preeclampsia which affects 5 to 7% of pregnancies is a significant cause of maternal & neonatal morbidity & mortality. Pre-eclampsia when complicated with generalized tonic-clonic convulsions and/or coma is called eclampsia. The term eclampsia is derived from a Greek word, meaning "like a flash of lightening". It may occur quite abruptly, without any warning manifestations. Eclampsia is a major cause of maternal mortality & morbidity as well as foetal loss worldwide, particularly in the third world. Appropriate measures & effective treatment of eclamptic patient in proper time reduce maternal mortality & morbidity. The mainstay of treatment of eclampsia is delivery of the foetus. Two methods are usually applied for delivery of foetus in eclampsia i.e. vaginal delivery & caesarean delivery. This study was done in the department of Gynae & Obs and department of Anaesthesiology, Mymensingh Medical College Hospital from 1st January 2016 to 30th June 2016 to observe the incidence, complications (morbidity) & mortality of eclamptic patients & which method (vaginal delivery versus caesarean delivery by spinal anaesthesia) is safe, better for the eclamptic patients as well as foetal mortality. Successful vaginal delivery is dependant on complex interactions of three variables (3 P) that is power (uterine contraction), passenger (foetus) & passage (birth canal) but power is less effective in eclamptic patient than normal partuents. Vaginal delivery requires prolong times compared with cesarean delivery. Anaesthetic technique is also an important factor for maternal mortality & morbidity of caesarean delivery. Spinal anaesthesia is widely regarded as a reasonable anaesthetic option for caesarean delivery in eclamptic patients. Currently the safety of spinal anaesthesia is well established and it can provide better obstetrical outcome when chosen properly. In this observation caesarean delivery by spinal anesthesia is safer, less complications, less maternal & neonatal mortality than vaginal delivery in eclamptic patients.

Abstract
This study was done to know the real status of immune response to Hepatitis B vaccine among the pentavalent vaccinated children as per EPI schedule of Bangladesh. It was prospective observational study done in the EPI corner of Paediatric OPD of Dhaka National Medical College & Hospital (DNMCH), Dhaka from July 2015 to July 2016. Sixty (60) children ranging from 9 months to 2 years of age, who received pentavalent vaccination (Hepatitis B + DPT + Hib) according to EPI schedule, were included. The testing for anti-HBs titres were conducted in the Department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Out of 60 children, 9(15%) had anti-HBs titres <10 IU/L (non-protected) while 51(85%) had anti-HBs titres >10 IU/L (protected). Twenty seven (27) were male and of them 21(77.8%) protective and 6(22.2%) non-protective. Thirty three (33) were female, out of them 30(90.9%) protective while 3(9.1%) non-protective. The difference was not significant between male and female (p=0.156). Fifty (50) children received vaccination by EPI (Government) (pentavalent) out of which 9(18%) non-protective and 41(82%) protective level. However, 10 children received privately Hepatitis B vaccination of which all developed protective level. The difference was not significant between Government (EPI) and privately vaccine (p=0.145). Most of the children showed positive immune response after pentavalent vaccination.

Abstract
One hundred and forty-six cases of rupture of the uterus during labour are reported and obstetric practice is described in Eastern Libya, where these disasters took place. The incidence and the causes of uterine rupture in Libya differ greatly from those in developed countries; high multiparity is a frequent cause. Hysterectomy is very often the best treatment. More than three-quarters of the children were lost, but 92% of the mothers were saved.

Abstract
Incision and drainage is the management plan of any infected sebaceous cyst from old age. But in infected sebaceous cyst, we can treat it in a simple way.Under local or general anesthesia the infected tissue is excised along with a rim of healthy tissue and then closed by Prolene in the same sitting. Usually stitches are removed on 21st day in the back and 14th day in the limb. This cross sectional observational study was carried out in the Department of Surgery of 250 Bed District Hospital, Kishoreganj and local clinics of Kishoreganj, Bangladesh from January 2012 to March 2015. One hundred (100) cases were selected with clinical diagnosis of infected sebaceous cyst and the procedure was carefully explained to every patients. The overall results were analyzed and it was revealed that with this method patients got quick recovery and no need for frequent dressing which prevents cross infection. It is cost effective and saves time also.

Abstract
Upper gastrointestinal hemorrhage (UGIH) is one of the most common and life-threatening gastrointestinal emergency. There are several risk scores for risk stratification in UGIB patients. The Modified Blatchford score, which relies only on clinical and laboratory parameters, is practical in the emergency setting The Modified Blatchford scoring system also known as Glasgow Blatchford Scoring (GBS) have been developed to stratify risk of non variceal upper gastrointestinal hemorrhage or need of medical or surgical intervention, endoscopic therapy. Objective of this study is to see risk stratification by The Modified Blatchford score and short term hospital outcome in non variceal upper GI hemorrhage patients. The observational study was carried out over a period of 6 months from October, 2014 to March, 2015 in Department of Department of Medicine, Gastroenterology and Surgery Mymensingh Medical College Hospital, Mymensingh. A total of 120 patients with non variceal UGIH were taken for the study during study period. Categorical variables were reported as percentage and Means and proportions were carried out using the Chi-square test (X2-test) of different variables by SPSS software version-18.0. Patients related variables age, sex; and main outcome variables the Modified Blatchford scoring system, Risk stratification, and short term hospital outcome were observed. Age frequency among total cases were 66(55%) <60 years, 50(41.67%) from 60-79 years and 4(3.3%) 80 years or above and sex distribution were 84(70%) were male and 36(30%) were female patients. Blatchford score of patients 1(0.83%) had score 0, 1(0.83%) had score 1, 2(1.67%) had score 2, 2(1.67%) had score 3, 2(1.67%) had score 4, 3(2.5%) had score 5, 12(10%) had score 6; 15(12.5%) had score 7, 16(13.33%) had score 8, 17(14.17%) had score 9, 16(13.33%) had score 10, 15(12.5%) had score 11, 10(8.33%) had score 12, 4(3.33% ) had score 13, 1(0.83%) had score 14, 2(1.67%) had score 15 and 1(0.83%) had score 16. Risk stratification showed 54(45%) had low risk (Mean GBS score 6.19±1.79), 66(55%) had high risk (Mean GBS score 11.03±1.83) Outcome of the patients were observed that 1(0.83%) died, 54(45%) was discharged without any medical or surgical intervention, and 65(54.17%) patients' needs medical or surgical intervention such as blood transfusion and endoscopy. Among total 120 patients with upper GI hemorrhage I have found that GBS score of three or less than three is predictive of low risk of adverse outcomes and can be discharged without any intervention.

Abstract
Lateral epicondylitis or Tennis elbow is very common repetitive stress injury or cumulative trauma disorder among active professionals and tennis players. Local steroid injection can provide quick functional improvement as sought by most of the patients. Therapeutic ultrasound and eccentric exercises can also improve the function. This study was carried out to see the comparative efficacy of these two modalities of treatments in terms of quicker functional improvement and this randomized interventional clinical trial was carried out in a private rehabilitation hospital in Dhaka. Patients attended the authors private chamber from January 2013 to December 2013 with clinical diagnosis of tennis elbow were included. Eighty adult patients diagnosed as lateral epicondylitis or tennis elbow were randomly divided into two groups. Group A received local steroid injection (triamcinolone acetate) and group B received therapeutic ultrasound for two weeks. Both the groups received eccentric exercises and advised to avoid provocative activities like twisting and lifting activities. Pain, tenderness and functional improvements were measured in traditional methods like visual analogue scale (VAS) and tenderness grade 0 to 4. Data were analyzed by SPSS. Most of the patients were female. None of them were tennis player. Younger housewives were common sufferer. Almost all patients in group A had very little or no pain or tenderness and no difficulty in lifting object at one week and two weeks. VAS was 13.62±6.503 and 4.15±5.517 respectively. Group B patients had mild improvement of pain and function at one week and moderate improvement at two weeks. VAS was 52.57±7.80 and 25.57±5.392 respectively. Similarly tenderness' were markedly improved in Group A at one and two weeks. They were 0.68±0.616 and 0.02±0.405 respectively for Group A and 1.60±0.553 and 1.14±0.335 respectively for Group B. Results were statistically significant in both groups at the end of two weeks. Local corticosteroid injections at extensor origin in tennis elbow patients are found to have better relief of pain and tenderness and quicker functional improvement than therapeutic ultrasound treatment. None of the patients were followed up for long term efficacy in either group.

Abstract
Bio-accessibility and bioavailability of arsenic (As) in historically As-contaminated soils (cattle tick pesticide), and pristine soils were assessed using 3 different approaches. These approaches included human bio-accessibility using an extraction test replicating gastric conditions (in vitro physiologically-based extraction test); an operationally defined bioaccessibility extraction test - 1.0M HCl extraction; and a live organism bioaccumulation test using earthworms. A sequential extraction procedure revealed the soil As-pool that controls bio-accessibility and bioaccumulation of As. Findings show that As is strongly bound to historically contaminated soil with a lower degree of As bio-accessibility (<15%) and bioaccumulation (<9%) compared with freshly contaminated soil. Key to these lower degrees of bio-accessibility and bioaccumulation is the greater fraction of As associated with crystalline Fe/Al oxy-hydroxide and residual phases. The high bio-accessibility and bioaccumulation of freshly sorbed As in pristine soils were from the exchangeable and specifically sorbed As fractions. Arsenic bioaccumulation in earthworms correlates strongly with both the human bio-accessible, and the operationally defined bioavailable fractions. Hence, results suggest that indirect As bioavailability measures, such as accumulation by earthworm, can be used as complementary lines of evidence to reinforce site-wide trends in the bio-accessibility using in vitro physiologically-based extractions and/or operationally defined extraction test. Such detailed knowledge is useful for successful reclamation and management of the As contaminated soils.

Abstract
The literature on adrenal gland tumour in HIV-infected patients is scarce. We report a 46-year-old Malay man with HIV and Hepatitis C infection presenting with a large nonfunctioning adrenal tumour. Computed tomography showed a large right adrenal tumour with heterogeneous enhancement and central necrosis. A high index of suspicion of a malignant tumour or pheochromocytoma led us to surgical removal of the adrenal gland. In this case report, we highlight important features to look for during pre-op evaluation of a large adrenal mass. Appropriate action should be taken when there is a suspicion of a pheochromocytoma or malignancy.

Abstract
Historic arsenic contamination of soils occurs throughout the world from mining, industrial and agricultural activities. In Australia, the control of cattle ticks using arsenicals from the late 19th to mid 20th century has led to some 1600 contaminated sites in northern New South Wales. The effect of aging in As-mobility in two dip-site soil types, ferralitic and sandy soils, are investigated utilizing isotopic exchange techniques, and synchrotron X-ray adsorption spectroscopy (XAS). Findings show that historic soil arsenic is highly bound to the soils with >90% irreversibly bound. However, freshly added As (either added to historically loaded soils or pristine soils) has a significantly higher degree of As-accessibility. XAS data indicates that historic soil arsenic is dominated as Ca- (svenekite, & weilite), Al-(mansfieldite), and Fe- (scorodite) like mineral precipitates, whereas freshly added As is dominated by mineral adsorption surfaces, particularly the iron oxy-hydroxides (goethite and hematite), but also gibbsite and kaolin surfaces. SEM data further confirmed the presence of scorodite and mansfieldite formation in the historic contaminated soils. These data suggest that aging of historic soil-As has allowed neoformational mineral recrystallisation from surface sorption processes, which greatly reduces As-mobility and accessibility.

Abstract
A soluble poly (n-vinyl carbazole)–polypyrrole (PNVC–Ppy) copolymer was prepared through oxidative chemical polymerization wherein dodecyl benzene sulfonic acid (DBSA) was used as a dopant to facilitate polymer-organic solvent interaction and ammonium persulfate (APS) was used as an oxidant. Compared with undoped PNVC–Ppy, the DBSA-doped PNVC–Ppy copolymer showed higher solubility in some selected organic solvents. The composition and structural characteristics of the DBSA-doped PNVC–Ppy were determined by Fourier transform infrared, ultraviolet–visible, and X-ray diffraction spectroscopic methods. Field emission scanning electron microscopic method was employed to observe the morphology of the DBSA-doped PNVC–Ppy copolymer. The electrical conductivity of the DBSA-doped PNVC–Ppy copolymer was measured at room temperature. The conductivity increased with increasing concentration of APS oxidant, and the highest conductivity was recorded at 0.004 mol/dm3 APS at a polymerization temperature of −5 °C. The increased conductivity can be explained by the extended half-life of pyrrole free radical at a lower temperature and a gradual increase in chain length over a prolonged time due to the slow addition of APS. Furthermore, the obtained soluble copolymer exhibits unique optical and thermal properties different from those of PNVC and Ppy.

Abstract
The aim of this study is to assess the optimum rehabilitation and the functional outcome of open repaired Achilles tendon ruptures. This study was conducted for the 18 consecutive patients of complete ruptures at Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from 2012 to 2013. Two groups were considered during 6 to 18 months post-operative observation and each group consist 9 patients. In the Group I, modified Teuffer's and in Group II, Lindholm operative methods were employed for the open repair of Achille tendon. The post operative outcomes were assessed for both of the groups through the modified Thermann's scores. In this study the patients median age was seen 39 years with 72.2% male and 27.8% female. The Thompson test was found positive in pre-operative and negative in post-operative outcome. The results shown that Achilles tendon ruptures occurred in 4 to 6cm rupture site, where the rupture side was 61.1% left and 38.9% right. The subjective overall assessment of total Thermann's scores were found very good (91 to 96) in 4 cases and (90 to 98) in 3 cases for Group I and Group II, respectively. Both of the operative techniques were found accountable results for rehabilitation. Therefore, based on the further statistical evidence of higher correlations and errors it may be concluded that Achilles tendon ruptures can be treated by modified Teuffer's or Lindholm technique.
