Abstract
This study aims to develop an exact analytical solution for steady-state thermo-mechanical stress in a functionally graded (FG) thick-walled cylindrical vessel. The cylinder is subjected to combined rotational speed and internal pressures while the thermal load is with convective and radiative boundary conditions. The dimensionless governing equations and boundary conditions, represented as a quartic equation, are derived and solved using Ferrari's method. The temperature, displacement, and stress fields across the thick-walled cylindrical vessel are calculated by finding the roots of the quartic equation. In order to investigate the accuracy of the exact analytical solution, a numerical model is constructed based on a standard Galerkin discretization approach of the finite element method (FEM). The analytical solutions and the results obtained through FEM show a high level of agreement. Furthermore, the study analyzes the effects of material parameters on temperature, displacement, and stress fields. Displacement, temperature, and stress fields are presented in the form of dimensionless graphs along the radial direction. For the considered parametric studies, results revealed that parabolic grading is beneficial than conventional grading. This study reveals that for the thermal loading, the maximum temperature, displacement, and tangential stress decrease for the parabolic grading. A similar but lower value of temperature, displacement, and tangential stress is also observed in the case of thermomechanical loading. This study is expected to assist in the assessment of the reliability of load calculations and contribute to the overall durability of pressure vessels. The results obtained from this study can provide valuable insights into thermo-elasticity and the thermo-mechanical behavior of thick-walled cylindrical vessels and can aid in the design and optimization of such systems.

Abstract
Background and Aim Bovine subclinical mastitis (SCM) is highly prevalent among dairy cattle. A cross-sectional study was conducted in Bangladesh to evaluate the performance of electric conductivity (EC) and total dissolved solids (TDS) tests for the detection of SCM. Materials and Methods We randomly selected 108 milk samples from cows of different breeds in the primary milk-producing region of Pabna and Sirajgonj districts of Bangladesh. Samples were subjected to the California mastitis test (CMT), white side test (WST), electric conductivity (EC), TDS, and culture. A cow was considered positive for SCM if it tested positive in CMT, WST, and culture, whereas a cow was considered negative for SCM if it tested negative in all three methods. These gold standards have been used to evaluate the performance of the EC and TDS tests. The optimal EC and TDS cutoff values for the detection of SCM were determined using the "optimal cutoff" function in R version 4.3.1. Results The optimal EC cutoff value for SCM detection was found to be 6159 μS/cm or 6.16 mS/cm. A positive likelihood ratio (LR+) of 31.2 and an area under the curve (AUC) of 0.905 were obtained for this cutoff value. The optimal cutoff value for TDS was 3100 mg/L of milk, which resulted in a positive LR+ of 45.5 and an AUC of 0.924. Conclusion To the best of our knowledge, this is the first study to evaluate the performance of EC and TDS tests in detecting SCM in Bangladesh. These results suggest that EC and TDS tests, which are inexpensive, rapid, and easy to conduct, can effectively detect SCM at the farm level.

Abstract
Covid-19 has become a pandemic since its emergence in Wuhan, China. It involves Gastro intestinal (GI) system and diarrhea is recognized as an important symptom. Diarrhea is also associated with disease severity. This study was conducted to see the prevalence of diarrhea in Covid-19 positive patient and its relation with disease severity. Prospective observational study done among consecutive Covid-19 positive patient of both sex admitted in Mugda Medical College Hospital in Dhaka from February 2021 to April 2021. Informations were collected by face to face interview and severity was assessed on bedside. Among 166 Covid-19 positive patient 40.0% developed diarrhea. Mean age of the diarrheal patients was 44.21±14.40. Women affected more than men (51.0% versus 49.0%). In majority patient (62.0%) diarrhea persist for 3-7 days and majority had frequency of bowel movement 3-5 times per day. Regarding Bristol stool type 47.0% had stool type 6 followed by stool type 7(43.0%) and stool type 5(10.0%). Half of the diarrheal patient (48.0%) had severe pneumonia. Severe pneumonia is significantly more common in non-diarrheal patients (65.0%) than in diarrheal patient (35.0%) (p=0.007). This study reflects that a large number of Covid-19 positive patients developed diarrhea. Half of the diarrheal patients had severe pneumonia. But severe pneumonia is significantly common in non-diarrheal patient than diarrheal patients.

Abstract
Cerebrovascular disease is the third most familiar cause of mortality worldwide and in Bangladesh. The reported prevalence of stroke in Bangladesh is 0.3%. Age, high serum glucose, elevated admission blood pressure, fever, large infarction size, and hyperhomocysteinemia has been reported to be risk factor for early post-stroke neurological deterioration. Early serum homocysteine level estimation can predict the early prognosis of ischemic stroke. In a developing country like Bangladesh, an earlier stroke outcome prediction for guiding therapeutic approach is essential. This study aimed to specify the role of estimating serum homocysteine during the early phase of acute ischemic stroke to assume an early prognosis that would guide- a management plan, the need to stay in the hospital and the need for intervention. This cross-sectional descriptive study was performed at the Department of Medicine, Mymensingh Medical College Hospital, Bangladesh from October 2021 to April 2022. Radiologically confirmed all ischemic stroke patients admitted at the Department of Medicine, Mymensingh Medical College Hospital, during the study period fulfilling the inclusion and exclusion criteria were included in this study. Non-probability purposive sampling technique was used. Data was collected using a pre-designed case record form. Quantitative data were represented as mean and standard deviation and qualitative data as frequency and percentage. The comparison was made by Chi-square test and independent samples t-test using SPSS (version 26.0). During the study period, among 716 stroke patients, 59 ischemic stroke patients were included in this study. The mean age of the patients was 64.0±11.72 years. After 72 hours of supportive treatment, early neurological outcomes were observed using NIHSS scoring. Out of 59 patients, the condition of 45(76.0%) patients improved or remained stable (END-) and the state of 14(24.0%) patients worsened (END+). Elderly age-raised temperature and elevated blood glucose level are known to increase infarction size, but only elevated temperature (p value 0.009) has statistical significance in this study. The mean homocysteine level ±SD was 20.22±6.95μmol/L, which is above the normal (<15μmol/L). The level was above average for both outcome groups. Serum homocysteine level was significantly higher in END(+) group (31.59±2.98μmol/L) than END(-) group (16.69±2.66μmol/L) and p value was <0.001.

Abstract
The conventional technique of harvesting free non-vascularized fibular grafting is associated with different scale of morbidity and usually a long scar. We follow a technique that causes minimum interference to the surrounding soft tissues to harvest the desired length of fibula. This prospective study was performed at Department of Orthopaedics, Dhaka Medical College Hospital from January 2018 to December 2018. Thirty patients of average age 10.5 years (range 8 to 14 years) were taken up for the study. The fibula was harvested by two separate incisions, 1 cm each at proximal and distal extent of proposed length of graft after elevating the periosteum circumferentially using a periosteum elevator. Compression bandage and above knee plaster immobilization was applied that help to reduce hematoma formation. The mean follow up is 12 months. The patients were evaluated clinically and by radiology. Twenty nine patients showed good results. One patient had delayed wound healing resulting in fair result. This modified approach of harvesting fibula reduces donor site morbidity and is safer and easier than conventional approach.

Abstract
Brachial plexus injury is not uncommon in our country like Bangladesh and it causes functional damage and physical disability of the upper limbs. Most of the cases were caused by motor vehicle accident. We have conducted a prospective study for the operative treatment of 105 adult traumatic brachial plexus injury cases in Hand unit in the department of Orthopaedics, Bangabandhu Sheikh Mujib Medial University (BSMMU) during January 2012 to July 2019. The main surgical options for brachial plexus injury include primary reconstructive surgery such as neurolysis, direct repair, nerve graft, nerve transfer (neurotization) and possibly free functioning (gracilis) muscle transfer and secondary reconstructive procedure such as tendon transfer, arthrodesis, FFMT and bony procedure. Each of these procedures is used either alone or in combination for particular clinical scenarios. Aims and objectives of this study was to restoration of shoulder abduction and external rotation, elbow flexion and hand function are goal of treatment of adult traumatic brachial plexus injury. Age range was from 14 years to 55 years (mean age 26 years). Male were 95 and female were 10 cases. Time from trauma to surgery was valid 3 months to 9 months. Motor cycle accident was most common mechanism of injury. Upper plexus (C5, C6) injury was 52 cases, extended upper plexus (C5, C6 & C7) injury was 19 cases and global brachial plexus injury was 34 cases. When there is high suspicion of root avulsions, early exploration and reconstruction is indicated. Operate these patients 2-3 months after their injury. In other patients without high suspicion of root avulsion, we routinely perform exploration between 3 to 6 months after injury when no adequate sign of recovery are present. Common reconstructive options are any injury with neuroma in continuity with conductive nerve action potential (NAP): only neurolysis or any injury with nerve rupture or postganglionic neuroma not conducting nerve Action potential (NAP) and good proximal nerve: Direct repair or repair with nerve graft or nerve transfer if possible. Follow up period from 6 months to 6 years. The best results were obtained in C5, C6 and C5, C6 & C7 brachial plexus injury cases. SAN to SSN, Oberlin II and long head triceps motor branch to anterior division of axillary nerve transfer for C5 & C6 injury or upper plexus injury and in addition intercostals nerve to anterior division of axillary nerve and AIN branch of median nerve to ECRB for C5, C6 & C7 (extended upper plexus injury). Extra-plexus and intra-plexus neurotization was done in global brachial plexus injury cases and 5 cases by contra-lateral C7 to median nerve by vascularised ulnar nerve graft and only 2 cases contra-lateral C7 to lower trunk through pre spinal or pre tracheal route were done and only one case by FFMT. Few cases gain shoulder abduction and elbow flexion but no improvement of hand function and most cases even by FFMT still in follow up. Results of surgical treatment of upper and extended upper brachial plexus injury cases were satisfactory on the other hand recovery of shoulder abduction and elbow flexion was acceptable and comparable to other study in global brachial plexus injury and recovery of hand function were poor.

Abstract
Congenital coronary ostial stenosis or atresia (COSA) is a spectrum of rare developmental conditions with different pathophysiologic mechanisms and clinical implications. Although COSA includes various entities, these entities have two features in common. First the defect is congenital, although it may progress during pre-natal and post natal life. Second the developmental defect may cause ostial or proximal coronary obstruction (that is stenosis or atresia). Coronary ostial stenosis or atresia affects the left coronary (L-COSA) more frequently than it does the right coronary artery. Systemic Lupus Erythematosus (SLE) is not an uncommon disease in young female, but combination of congenital coronary ostial stenosis with systemic lupus erythematosus make the case very rarer. Here we presented A 17 years old girl got admitted to Bangabandhu Sheikh Mujib Medical University, Bangladesh for evaluation of on and off chest pain of CCS-III to CCS-IV for 1 day on 17 September 2019.

Abstract
A prostate gland biopsy is a test to remove small sample of prostate tissue to be examined under a microscope. A biopsy may be done when a blood test shows a high level of prostate-specific antigen (PSA) or after a digital rectal examination finds an abnormal prostate or a lump. Transrectal ultrasound (TRUS) guided biopsy is a commonly performed procedure for the detection of prostate cancer. It is associated with serious complication like urosepsis. Although the incidence of post-TRUS urosepsis is low, when it occurs it is typically serious and leads to hospitalization. Antibiotics are used prior, during and after the procedure to prevent infections as a result of TRUS biopsy. Ciprofloxacin is being used as antibiotic of choice for a long time. Antibiotic prophylaxis may prevent such complications. This cross-sectional descriptive type of observational study was taken place in Dhaka Medical College Hospital, Dhaka, Bangladesh from January 2010 to December 2011 among purposively selected 70 patients with an aim to determine the urosepsis and bacteriuria after TRUS guided prostate biopsy. Patients attending the Urology OPD in DMCH having of LUTS and other non-specific symptoms were evaluated by history, physical examination including digital rectal examination (DRE) and necessary investigations like serum PSA to identify the potential candidates. Patients with abnormal DRE findings and increased PSA level were included in this study and those who had any painful anal and rectal condition, bleeding diathesis, anticoagulant therapy and any known allergy to lidocaine, previously undergone prostrate biopsy and those who refused to give the informed consent were excluded from this study. Data were collected on variables of interest using a structured case record form. Data were processed and analyzed using Statistical package for social science (SPSS), version 17.0. Frequency of bacteriuria and urosepsis was measured according to urine and blood culture report. Sensitivity pattern was also seen. According to this study, the frequency of bacteriuria and urosepsis was 17.1% and 5.7% respectively. Most common uropathogen was E coli both in urine and blood culture. Organisms (100.0%) were found resistant to ciprofloxacin and amoxicillin. Most of the pathogens were sensitive to tobramycin, gentamycin and cefipime. A potentially dangerous ciprofloxacin resistant organism (ESBL producing E. coli) was found positive in 25.0% of culture positive patients.

Abstract
Core body temperature (CBT) regulation is crucial for mammalian wellbeing and survival. Cattle pant to dissipate excess heat to regulate CBT when ambient conditions exceed thermoneutral zones. However, to date, neither the variability in cattle heat response, the lagged response of CBT to thermal indices, nor the diurnal patterns of thermal indices, CBT and panting have been reported in the literature. We decomposed thermal indices, CBT and panting time-series data for 99 feedlot heifers across three discrete heat events into diurnal, trend and residual components. Both raw and decomposed data were analysed to explore the lagged CBT and panting responses and the association between series. We show ambient thermal conditions impact CBT with a 1-h lag despite a lag of between 1.5 to 3 h from raw data. Average individual panting scores were used to identify heat-susceptible and heat-tolerant cattle. Heat-susceptible cattle showed greater CBT (P < 0.01) between 8:00 and 23:00 and greater panting duration (P < 0.05) between 10:00 and 18:00 than heat-tolerant cattle under the same thermal conditions and these variations followed a similar pattern despite differences in cattle breed. This new information enables targeted amelioration and selection of individuals against heat susceptibility.

Abstract
The objective of this study was to figure out the prevalence and probable causes of repeat breeding (RB) in dairy cows. Hence, a cross-sectional study was conducted on randomly selected 265 dairy farms in Sirajganj, Bogura, Rangpur, Satkhira, and Munshiganj districts of Bangladesh from December 2018 to February 2019. Data were collected through a direct interview method using a survey questionnaire. The reproductive organs of repeat breeder cows were examined for pathological, infectious, and functional reasons, and genital tract abnormalities. Additionally, the influence of nutrition, season, and age on the frequency of RB was recorded. The prevalence of RB was 28% among the 3824 cows investigated. Among the total repeat breeder cases, 72.54% of RB cases were found in Holstein-Friesian crossbred, 23.90% in Jersey crossbred, 1.50% in Sahiwal crossbred, and 2.06% in indigenous cows. The prevalence of RB was significantly highest (P < 0.01) in Satkhira (44.35%) and lowest in the Munshiganj district (15.87%). Data indicated that a major proportion of cows significantly (P < 0.05) faced RB problems due to functional causes (34.18%), followed by pathological causes (28.01%), genital tract abnormalities (21.32%), and infectious causes (16.49%). Furthermore, the cows were remarkably (P < 0.001) affected in RB during the summer season and nutritional deficient diseases like milk fever (70%). Age (3-7 years) had a significant (P < 0.001) effect on the RB occurrence (90%) in crossbred cows. However, particular focus should be given to systematic breeding, balanced nutrition, artificial inseminator efficiency, and hygienic inseminating tools to reduce RB incidence in high-yielding crossbred cows.

Abstract
Thermoluminescence (TL) materials have a broad variety of uses in various fields, such as clinical research, individual dosimetry, and environmental dosimetry, amongst others. However, the use of individual neutron dosimetry has been developing more aggressively lately. In this regard, present study establishes a relationship between the neutron dosage and the optical property changes of graphite-rich materials caused by high doses of neutron radiation. This has been done with the intention of developing a novel, graphite-based radiation dosimeter. Herein, the TL yield of commercially graphite-rich materials (i.e. graphite sheet, 2B and HB grade pencils) irradiated by neutron radiation with doses ranging from 250 Gy to 1500 Gy has been investigated. The samples were bombarded with thermal neutrons as well as a negligible amount of gamma rays, from the nuclear reactor TRIGA-II installed at the Bangladesh Atomic Energy Commission. The shape of the glow curves was observed to be independent of the given dosage, with the predominant TL dosimetric peak maintained within the region of 163 °C-168 °C for each sample. By studying the glow curves of the irradiated samples, some of the most well theoretical models and techniques were used to compute the kinetic parameters such as the order of kinetics (b), activation energy (E) or trap depth, frequency factor (s) or escape probability, and trap lifetime (τ). All of the samples were found to have a good linear response over the whole dosage range, with 2B grade of polymer pencil lead graphite (PPLGs) demonstrating a higher level of sensitivity than both HB grade and graphite sheet (GS) samples. Additionally, the level of sensitivity shown by each of them is highest at the lowest dosage that was given, and it decreases as the dose increases. Importantly, the phenomenon of dose-dependent structural modifications and internal annealing of defects has been observed by assessing the area of deconvoluted micro-Raman spectra of graphite-rich materials in high-frequency areas. This trend is consistent with the cyclical pattern reported in the intensity ratio of defect and graphite modes in previously investigated carbon-rich media. Such recurrent occurrences suggest the idea of employing Raman microspectroscopy as a radiation damage study tool for carbonaceous materials. The excellent responses of the key TL properties of the 2B grade pencil demonstrate its usefulness as a passive radiation dosimeter. As a consequence, the findings suggest that graphite-rich materials have the potential to be useful as a low-cost passive radiation dosimeter, with applications in radiotherapy and manufacturing.

Abstract
Hearing loss can be congenital or acquired. Most of the time congenital hearing loss means profound sensorineural hearing loss. The invention of cochlear implantation has already an established role in improving the hearing capability in congenital sensorineural hearing loss. To speak properly after cochlear implant, one needs to go for speech therapy or audio-verbal therapy. Speech therapy has become an integral part of the cochlear implantation program. In Bangladesh cochlear implantation (CI) programs started around 15 years ago, which was limited to Bangabandhu Sheikh Mujib Medical University (BSMMU) and Combined Military Hospital (CMH). Our government takes initiative to provide this service to poor and lower income people. National Institute of ENT (NIENT) was the first government hospital where CI started in 2018 and the project is now ongoing. After CI auditory, verbal therapy (AVT) was given at the same institute. No study has not been done to find out the outcome of AVT. NIENT has taken steps to find out the functional and speech outcome of cochlear implanted children considering the two standard criteria: CAP and SIR score. This retrospective study was done to find out the auditory verbal outcome of unilaterally CI children in different ages and conducted at department of Audiology, National Institute of ENT, Tejgaon, Dhaka, Bangladesh from January 2021 to June 2021. The children who underwent cochlear implants and took the auditory verbal therapy were included in this study. Though it is a retrospective study, a written informed consent has been taken from the patient's parents as the cases are minor in age. From the record review, CAP and SIR scores were recorded four times: before implantation 1 time, after cochlear implantation 3 times (At the end of 3, 6 and 12 months after starting of AVT of Cochlear implantees). From the study it has been observed that out of 50 implantees, 48.0% of children's age range was in between >3 to ≤5 years. Most of the implantees were from rural areas and also from lower income group. The study showed significant association with CAP and SIR score at the end of one year of AVT. No significant association was found in different age groups with scores of CAP and SIR. But the parent's education showed significant association with CAP score at the end one year of AVT. Though the age of the recipient is not significantly associated with the AVT outcome but maternal education plays an important role in improving CAP and SIR score. So, maternal education or understanding along with professional speech therapy is vital for better AVT outcome.

Abstract
Well established and common practice in conservative management of omphalocele major is escharotics therapy with different topical agents. Among them mercurochrome, alcohol, silver salts, povidone iodine, acacia nilotca paste are commonly used. It is a comparative study between application of acacia nilotica paste and povidone iodine solution as a primary non surgical treatment of omphalocele major regarding efficacy and safety of these two topical agents. A double blind randomized controlled study was conducted at the department of Paediatric Surgery, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from July 2016 to June 2019. In this study 20 cases of omphalocele major and randomly divided into two equal groups. Group A and Group B treated with acacia nilotica paste and povidone iodine solution respectively. Gastroschisis, ruptured-omphalocele major or omphalocele minor excluded in this study. The size of the fascial defect in cm, time required for full oral feeding tolerance and duration of hospital stay were evaluating parameters. Patients with Group A tolerated full oral feeding earlier, shorter total hospital stay duration and low mortality rate than those from Group B. Application of acacia nilotica is a safe and effective treatment of omphalocele major regarding rapid full oral feeding tolerance, shorter hospital stay and low mortality rate.

Abstract
The correct approach to treat low-risk intra thyroidal papillary thyroid carcinoma (PTC) is still controversial. The traditional paradigm of treating all patients with thyroid cancer with total thyroidectomy, radioactive iodine and suppressive thyroid hormone therapy is no longer suitable. Many authors advocate unilateral thyroidectomy to minimize perioperative morbidity. The purpose of this study was to determine an effective treatment strategy for patients with small unilateral papillary thyroid carcinoma in a low risk group. This is a prospective study of 300 patients who were diagnosed as papillary thyroid carcinoma by preoperative FNAC or postoperative histopathology. The age of the patients' was ranged between 15 to 45 years. The criteria were: tumor ≤4cm, unilateral involvement, cytological non-aggressive subtype, absence of lymph node (LN) involvement and extra thyroidal extension (ETE) on ultrasonography (USG) and absence of clinical distant metastases. Duration of the study period was 30 years from 1989 to 2019. The study was conducted in tertiary care hospital in Bangladesh. All patients had undergone hemi thyroidectomy and followed up by a median period of 25 months (range, 6 to 166 months). Following hemithyroidectomy, among 300 patients, 267 patients (89.0%) did not show any recurrence of disease. Thirty three (33) patients (11.0%) came with locoregional recurrence of disease in clinical and USG findings without any distant metastasis. Maximum patients were between the ages 31-40 year followed by 21-30 years. Female was out number male in the ratio. Though further large scale study should require to determine the optimal treatment option for low risk PTC, but this study can lead to a result that hemi thyroidectomy is now-a-days a better surgical option for PTC even up to tumor size of ≤4cm.

Abstract
Among all mandibular fracture 25.0 to 40.0% fractures are regarded as condylar and subcondylar fracture. Commonly, reduction of subcondylar fracture is done under general anaesthesia. Different approaches were found for the surgical treatment of condylar fractures besides intraoral approaches such as the pre-auricular, submandibular, rhytidectomy, retromandibular. This is a prospective observational study which was performed to find out the outcome of retromandibular approach for subcondylar fracture treatment of mandible i.e. to find out correction of occlusion and establishment of jaw function, infection, hematoma, salivary fistula, facial nerve damage, haematoma etc complication. Surgical treatment of subcondylar fractures of 15 patients was done in Dhaka Dental College and Hospital and different private centres in Dhaka and Mymensingh, Bangladesh from January 2019 to December 2021 in retromandibular transparortid approach. The patients were evaluated for hematoma, infection, Frey's syndrome, salivary fistula, facial nerve damage, occlusion, fracture site stability, chronic pain in the fracture site and temporomandibular joint movements in the post operative period. Facial nerve injury was not observed. Postoperative swelling of parotid region developed in first two patients. Single patient developed paresis in zygomatic branch of facial nerve causing left upper eyelid muscle weak and after two weeks of physiotherapy it became normal. Salivary fistula developed in three patients which resolved spontaneously. Outcome of this approach like good anatomy and function was found in all cases. Good articular function was obtained in all the cases. By this retromandibular approach condylar fracture reduction; fixation and healing were managed comfortably. However, direct vision of facial nerve fibres has limited the risk of facial nerve injury.

Abstract
Though cervical cancer is a preventable disease it is the most progressive and devastating diseases posing a threat of mortality for women of developing countries. Majority of the cases present to hospital at advanced stage when treatment is less feasible. Objective is to determine the factors associated with the advanced stage presentation to the hospital, socio-demographic factor, patterns of complications and histological types among patients with carcinoma cervix. This was an observational descriptive type of cross-sectional study carried out in the department of Obstetrics and Gynecology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from 15 January to 27 September 2017. Women who were newly confirmed to have cervical cancer by histology were enrolled. Stages IIB and above was considered as advanced disease. The patients were interviewed face to face by the researcher for the purpose of collection of data. Then the patients were examined by the researcher for certain sings and those would be recorded in the check-list. Histopathological report was noted in data collection sheet. In this study data analysis was done by SPSS version 22.0. Total 66 clinically and histologically confirmed advanced ca-cervixes were taken up during this study. Most common stage was stage III, 49(74.2%) out of 66 population. Majority of female were found 34(51.5%) in age group 51-60. More than half of population 54(81.8%) were living with their husband and 12(18.1%) were widow at the time of study. High level of illiteracy among women and their problematic health seeking behavior for gynecological symptoms are responsible for advanced diagnosis of cervical cancer.

Abstract
Background
The study was aimed to estimate the true prevalence of human tuberculosis (TB); identify risk factors and clinical symptoms of TB; and detect rifampicin (RIF) sensitivity in three study areas of Bangladesh.
Methods
The cross-sectional study was conducted in three Bangladesh districts during 2018. Potential risk factors, clinical symptoms, and comorbidities were collected from 684 TB suspects. Sputum specimens were examined by LED microscopy. TB hierarchical true prevalence, risk factors and clinical symptoms were estimated and identified using a Bayesian analysis framework. Rifampicin sensitivity of M. tuberculosis (MTB) was detected by GeneXpert MTB/RIF assay.
Results
The median TB true prevalence was 14.2% (3.8; 34.5). Although overall clustering of prevalence was not found, several DOTS centers were identified with high prevalence (22.3% to 43.7%). Risk factors for TB identified (odds ratio) were age (> 25 to 45 years 2.67 (1.09; 6.99), > 45 to 60 years 3.43 (1.38; 9.19) and individuals in families/neighborhoods where a TB patient(s) has (ve) already been present (12.31 (6.79; 22.60)). Fatigue, night sweat, fever and hemoptysis were identified as important clinical symptoms. Seven of the GeneXpert MTB/RIF positive sputum specimens (65) were resistant to rifampicin.
Conclusions
About one in every seven TB suspects was affected with TB. A number of the TB patients carry multi drug resistant MTB. Hierarchical true prevalence estimation allowed identifying DOTS centers with high TB burden. Insights from this study will enable more efficient use of DOTScenters-based TB surveillance to end the TB epidemic in Bangladesh by 2035.

Abstract
The tendo achilles is one of most important tendon in human body which often injured through direct trauma or indirect stress on a weakened tendon. Longer the duration after injury the injured parts likely to move apart, fibrosis and degeneration leading to difficulty in repair or reconstruction. Usually a phase of 4 weeks or more without specific treatment is regarded as chronic or neglected rupture. Different authors described many management protocols about the tendo achilles rupture but there is no procedure of choice for neglected rupture with long gap. Prospective case series of 21 patients of neglected tendo achilles rupture with long gap treated with flexor hallucis longus tendon (FHLT) transfer was taken for study from January 2019 to December 2020 in Mymensingh Medical College Hospital, Bangladesh. Average age of patients was 39.47 years with range 22-65 years. Fifteen (15) cases of traumatic rupture in this study with average age 32.66 years and pathologic 6 cases with average age 56.5 years were recorded. We grafted FHLT from channel by incising Henry's knot. Krackow et al.'s technique was followed for tendon mobilization and bone fixation. We made procedure simpler and cheaper; instead of using interference screw the sutured tendon pulled through the heel and anchored over rubber tube or button by Cole method. Post-operative complications were less with one patient with superficial infection which eventually recovered 3 cases of mild pain and 2 cases of numbness. Questionnaire for surgical outcome measure are satisfactory in 19 patients (90.47%). Final follow up AOFAS score at 6 month (91.61±5.41) was highly significant (p<0.001) in comparison to preoperative score (38.71±9.78). These are comparable to other study. Above mentioned scores indicate the reliability of the surgical system. But our study is a prospective case series with minimum cases. To establish the best procedure for neglected tendo achilles rupture with long gap we recommend further study with larger group and Randomized Controlled Trial (RCT) study among different procedure.

Abstract
This research work focuses on the magnetic properties, nature of the magnetic phase transition, magnetocaloric effect, and critical scaling of magnetization of various Co1−xCrxFe2O4 (x = 0, 0.125, 0.25, 0.375, and 0.5). The tunability of the magnetic moment, exchange interactions, magnetocrystalline anisotropy constant, and microwave frequency using Cr3+ content has been found. The nature of the magnetic phase transitions for all the Cr3+ concentrations exhibits as second order which has been confirmed from the analysis of critical scaling, universal curve scaling, and scaling analysis of the magnetocaloric effect. The critical exponent analysis for all samples was performed from the modified Arrott-, and Kouvel–Fisher-plots. These critical analyses suggest that x = 0.125, 0.250, and 0.375 samples show reliable results in the magnetocaloric effect with relative cooling power (RCP) values in the range of 128–145 J kg−1. On the other hand, x = 0.00, and 0.500 samples exhibit inconsistent RCP values. The universal curve scaling also confirms the reliability of the magnetocaloric effect of the investigated samples. Magnetic entropy change as a function of temperature for various Co1−xCrxFe2O4 at an applied magnetic field of 5 T.![]()

Abstract
Coronary artery disease is one of the most prevalent causes of increasing mortalitiy in current time. Early detection of such dreadful condition by a non-invasive test like exercise treadmill test, is a much-required option to prevent future complications like myocardial infarction. The aim of this study was to find out how different the predictability of simple treadmill score in comparison to other treadmill scores namely the well-known Duke treadmill score and Cleveland clinic score. In a cross-sectional analytical study of total 130 individuals with stable angina were included according to criteria set before the study. The treadmill scores of these patients were calculated and compared to coronary angiogram findings where coronary artery angiograms were done according to clinical need. Simple treadmill test had similar predictability for coronary artery disease when we compared it with much-applied Duke Treadmill Test and Cleveland Clinic Score- which is currently used for mortality prediction. Receiver Operator Characteristics (ROC) Curve showd all scores had around 0.7 area under the curve (AUC) which is highly statistically significant (p<0.0001) though simple treadmill score in females has higher sensitivity (92.3%). Simple treadmill score can be considered to exclude female patients from undergoing invasive investigation as it has higher sensitivity than other currently practiced treadmill scores i.e., Duke treadmill score.

Abstract
BACKGROUND The use of antihypertensive medications is critical for controlling high blood pressure. We aimed to investigate associations between socio-demographic factors and antihypertensive medications use, and antihypertensive medications use with different types of drugs use with levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP). METHODS For the present report we derived data from the baseline measurements of a cluster randomised control trial on 307 participants with previously diagnosed hypertension from the rural district of Narial in Bangladesh. We measured the participant's current blood pressure levels and recorded antihypertensive medications uses. Associated factors included socio-economic status, diabetes, antihypertensive medications use, and types of drugs and doses used for controlling blood pressure. We applied analysis of variance and logistic regression techniques to identify factors associated with blood pressure. RESULTS Of the total participants, 144 (46.9%) were on antihypertensive medications. After multivariate adjustment, binary logistic regression revealed that employees (odds ratio, (95% confidence interval (CI)) (OR 3.58, 95%CI 1.38-9.28) compared to farmers, and people with diabetes (OR 2.43, 95%CI 1.13-5.26) compared to people without diabetes were associated with a higher proportion of antihypertensive medications use. Of 144 participants on antihypertensive medications, 7 (5%) had taken two doses, 114 (79%) had taken one dose per day and the rest were irregular in medication use. The mean (standard deviation) [min, max] SBP and DBP were 149 (19) mmHg [114, 217] and 90 (10) mmHg [75, 126], respectively. Overall, there was no significant difference in SBP (p = 0.10) or DBP (p = 0.67) between participants with or without antihypertensive medications or using any type of medications (p = 0.54 for SBP and 0.76 for DBP). There was no significant association between antihypertensive medications use and elevated BP levels SBP/DBP≥140/90 mmHg (p = 0.42) CONCLUSION: Less than half of the people with hypertension were on medication. Irrespective of the antihypertensive medications use, most of the participant's blood pressure was high. Further study is needed with a large sample to understand the factors and aetiology of unmanaged hypertension in rural areas of Bangladesh where the prevalence of hypertension is very high.

Abstract
Hepatitis B virus infection is an important cause of liver disease. Hepatitis B Virus may present with varying degree of severity. In older children, 5-10% cases leading to chronic liver disease, cirrhosis and hepatocellular carcinoma. This descriptive cross sectional study was done to assess the prevalence of Hepatitis B Virus infection among hospitalized children with liver disease in pediatric department of Mymensingh Medical College Hospital, Bangladesh from December 2015 to October 2016. All the children of both sexes having age between six months to twelve years admitted in the pediatric ward with acute or chronic liver disease were included in this study by purposive sampling. A written consent was obtained from legal guardian of children before inclusion. Ethical clearance was obtained from competent authority. A detailed history was taken from parents in each case according to pre-designed questionnaire about demography of the patients and the risk factors of the liver disease. A thorough clinical examination and available relevant investigations like serological testing for HBV infection was done in all patients. We had figure out the seropositivity of HBV among patients having liver disease by doing HBsAg and Anti-HBc IgM. Progress of the patient was monitored by daily clinical examinations and by investigating HBsAg and Anti-HBc IgM. Finally data analysis was done by SPSS version 21.0. Among total 100 patients most (44%) patients were in 7-10 years old and most (62%) of the participants were male. Acute liver disease was 58% cases and chronic liver disease was 42% cases. HBsAg was positive in 1 case among acute liver disease and 5 cases among chronic cases. Total 6 (six) patients were found positive for HBsAg. Anti HBc IgM was positive in 4 patients among acute liver disease. Among these Anti HBc IgM positive (4) patients only one had both HBsAg and Anti HBc IgM positive. So, four patients were confirming suffered from acute viral hepatitis because they had anti HBc IgM positive. On the contrary 5 patients suffered from chronic hepatitis by hepatitis B because they were only HBsAg positive. So, in this study 9 patients (9%) were confirming suffered from HBV infection. Possible transmission factors of hepatitis B were history of (H/O) blood transfusion/trauma/parenteral injection, H/O umbilical sepsis, H/O maternal illness/infection during pregnancy. HBV still is a major cause of morbidity. All the children with liver disease should be routinely tested for HBV.

Abstract
BACKGROUND High blood pressure is an independent risk factor of cardiovascular disease (CVD) and is a major cause of disability and death. Managing a healthy lifestyle has been shown to reduce blood pressure and improve health outcomes. We aim to investigate the effectiveness of a lifestyle modification intervention program for lowering blood pressure in a rural area of Bangladesh. METHODS A single-center cluster randomized controlled trial (RCT). The study will be conducted for 6 months, a total of 300 participants of age 30 to 75 years with 150 adults in each of the intervention and the control arms. The intervention arm will involve the delivery of a blended learning education program on lifestyle changes for the management of high blood pressure. The education program comprises evidence-based information with pictures, fact sheets, and published literature about the effects of high blood pressure on CVD development, increased physical activity, and the role of a healthy diet in blood pressure management. The control group involves providing information booklets and general advice at the baseline data collection point. The primary outcome will be the absolute difference in clinic SBP and DBP. Secondary outcomes include the difference in the percentage of people adopting regular exercise habits, cessation of smoking and reducing sodium chloride intake, health literacy of all participants, and the perceived barriers and enablers to adopt behavior changes by collecting qualitative data. Analyses will include analysis of covariance to report the mean difference in blood pressure between the control and the intervention group and the difference in change in blood pressure due to the intervention. DISCUSSION The study will assess the effects of physical activity and lifestyle modification in controlling high blood pressure. This study will develop new evidence as to whether a simple lifestyle program implemented in a rural region of a low- and middle-income country will improve blood pressure parameters for people with different chronic diseases by engaging community people. TRIAL REGISTRATION ClinicalTrials.gov NCT04505150 . Registered on 7 August 2020.

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
Among the various types of decorative materials used in Bangladeshi dwellings, the marble/marble stone is one of the most common ones that used largely for enhancing the beauty and/or aristocracy of the dwelling environment. In this study, the most commonly used, six types of marble stones, have been analyzed for retrospective accident dosimetry. With the interest of characterizing several key thermoluminescence properties to examine their potentiality for dosimetry, annealing - irradiation - readout steps have been done chronologically which comprises the analysis of glow curves, relative sensitivity, dose dependence, repeatability and fading. Considering the various TL parameters, marble 'Carrara' imported from Italy present relatively better capability for reconstruction of radiation dose in the dose range of 10-50 Gy. From fading result, it is clear that for reconstruction of absorbed dose up to four weeks of post exposure, the marble 'Carrara' is found to be the most reliable media among the studied marble types. The Zeff values for the various marble samples are found to be in the range of 13.65-19.12, comparing favorably in replace of TLD-200 (Zeff = 16.3) which can be used for low-level environmental radiation dosimetry. Present work constitutes the first study to investigate the potentials of marble stone for reconstruction of absorbed dose in the range of 10-50 Gy dose.

Abstract
BACKGROUND The green synthesis strategy of metallic nanoparticles (NPs) has become popular due to being environmentally friendly. Stable silver nanoparticles (AgNPs) have been synthesized by natural products such as starch, soy protein, various extract of leaves, barks, and roots functioning both as reducing and stabilizing agents. Likewise, silk sericin (SS) is a globular protein discarded in the silk factory might be used for NP synthesis. In this research, we focus on the green synthesis and stabilization of AgNPs by SS as well as assessment of their antibacterial activities against some drug-resistant pathogen. RESULTS SS was extracted from Bombyx mori silkworm cocoons in an aqueous medium. 17 w/w% of dry sericin powder with respect to the cocoon's weight was obtained by freeze-drying. Furthermore, AgNPs conjugated to sericin, i.e., SS-capped silver nanoparticles (SS-AgNPs) were synthesized by easy, cost-effective, and environment-friendly methods. The synthesized SS-AgNPs were characterized by UV-visible spectroscopy, Fourier-transform infrared-attenuated total reflection (FTIR-ATR) spectroscopy, transmission electron microscopy (TEM), and X-ray diffraction measurement. It has been found from the absorbance of UV-visible spectroscopy that a higher percent of SS-AgNPs was obtained at a higher concentration of silver nitrate solution. FTIR-ATR spectra showed that the carboxylate groups obtained from silk sericin act as a reducing agent for the synthesis of silver nanoparticles, while NH2+ and COO- act as a stabilizer of AgNPs. The X-ray diffractogram of SS-AgNPs was quite different from AgNO3 and sericin due to a change in the crystal structure. The diameter of AgNPs was around 20-70 nm observed using TEM. The synthesized SS-AgNPs exhibited strong antibacterial activity against multidrug-resistant pathogens, Escherichia coli and Pseudomonas aeruginosa. Minimal inhibitory/bactericidal concentrations against E. coli and P. aeruginosa were 20μg/mL. CONCLUSIONS This study encourages the use of Bombyx mori for the ecofriendly synthesis of SS-AgNPs to control multidrug-resistant microorganisms.

Abstract
Cellular death of bone due to impairment of the blood supply leading to collapse resulting in pain, and loss of joint function is known as avascular necrosis (AVN). The head of femur is the most common bone affected by avascular necrosis followed by talus and scaphoid. We evaluate the results of core decompression with non-vascularized fibular graft in avascular necrosis of femoral head. This quasi experimental study was done at Mymensingh Medical College Hospital, Dhaka Medical College Hospital and some other private hospitals of Bangladesh. The study includes patients who underwent core decompression and non-vascularized fibular grafting in avascular necrosis of femoral head from January 2017 to December 2018. In this study we evaluated total 20 patients and majority of the patients belongs to the group of 20-30 years. Out of 20 patients, 8 of them were unilaterally involved rest 12 had bilateral involvement. Out of 24 hips of bilateral involvement 4 were grade III and IV (Ficat and Arlet classification) therefore not included in the study. So, we study 28 hips only. The average success rate was 90% after core decompression and non-vascularized fibular bone grafting. Harris hip score of 60 on presentation had poorer outcome. Patients with less than 80 degrees of flexion had poorer outcome.

Abstract
The cross sectional descriptive type of observational study was aimed to evaluate the association of serum free testosterone in 59 patients of carotid atherosclerotic male {<50% stenosis (n=26); >50% stenosis (n=33) } from March 2015 to February 2016 in the Department of Radiology & Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU) & National Institute of Neurosciences (NINS), Dhaka, Bangladesh. Twenty seven patients who had normal carotid doppler findings were taken as control. Serum total testosterone and sex hormone binding globulin was measured by chemiluminescence micro particle immunoassay and free testosterone was done by using Vermeulen formula. Concentration of free testosterone differed significantly among groups (p=0.004) and it was significantly lower in <50% stenosed group. Logistic regression analysis revealed that low free testosterone (free testosterone ≤0.24 nmol/L) was independently associated with development of carotid atherosclerosis (p=0.04, OR 3.07, 95% CI 1.14-9.30). In conclusion low serum free testosterone was associated with carotid atherosclerosis in male.

Abstract
Low back pain (LBP) is a common problem and is an important public health issue. A major proportion of LBP is concomitant with prolong and repetitive awkward postures, related with occupation like miners, health workers and professional drivers. Physicians are exposed to a wide range of occupational risk factors which results in LBP. A variety of occupational and personal factors are responsible for increased risk of low back pain among physicians. This cross sectional descriptive study was carried out at Mymensingh Medical College Hospital during the period of January 2018 to June 2018, to estimate the proportion of LBP among physicians. Data were collected from purposively selected 102 physicians of different levels by face to face interview using a case record form. Informed written consent of participants was taken prior to interview. Data were analyzed by using SPSS version 20.0. The study results revealed that majority (60.8%) of the physicians were in the age group of 31-50 years. Mean age of the physicians was 49.9 years with a standard deviation (SD) of 3.61 years. More than three fourth (79, 77.5%) of the physicians were male and 23(22.5%) were female. Out of 102 physicians more than two third (70, 68.6%) had LBP while 32(31.4%) did not have any LBP. Proportion of low back pain among physician was 68.6%. Low back pain was found in all age group. Among the physicians having low back pain, 55(78.6%) were male and 15(21.4%) were female. Among 102 physicians, 45(44.1%) had different types of comorbidities while 57(55.9%) did not have any comorbidities. Among the co-morbidities HTN, DM, Dyslipidemia, CHD and asthma were common. Results of the study concluded that 68.6% physicians had low back pain. Physicians of age group 31-60 years (88.5%) and male (78.6%) experienced LBP more. Further multi-centric large scale case control study is recommended to determine the risk factors of LBP among physicians of Bangladesh.

Abstract
Background: The World Health Organization (WHO) and the International League Against Rheumatism (ILAR) initiated the Community-Oriented Program for the Control of Rheumatic Diseases (COPCORD) project in 1981. The aim of this study was to translate the revised WHO-ILAR COPCORD questionnaire into Bengali and to test if the Bengali version could be reliably used for the identifying rheumatic diseases in Bangladeshi people.Methods: This was an observational study conducted in rheumatology wing, department of medicine, BSMMU from April to October, 2011. It was implemented in two stages: Translation and cross-cultural adaptation of questionnaire and testing of questionnaire. For translation into Bengali and cross-cultural adaptation, the recommendation by Beaton’s procedure was followed. Respondents were enrolled from rheumatology outpatient departments of medicine, BSMMU, household members and healthy patient’s attendants. Data were collected and analyzed using SPSS windows v16.Results: Thirty subjects completed the preliminary version of the questionnaire. Fifteen males (50%) and fifteen (50%) females were interviewed. Mean age of the respondents were 31.97±10.15 with age range 16-55 years. Test-retest reliability of the Bengali version of the questionnaire was tested by interviewing 70 subjects. To evaluate agreement between two measurement qualitative questions were analyzed using kappa test and quantitative question were tested by spearman’s correlation. Most of the questions (88.2%) showed high or good agreement (kappa agreement >0.6) and one (5.88%) question showed moderate agreement (0.4-0.6). In case of quantitative questions responses in test and re-test were found to have 50% good correlation and remainder poor correlation in Spearman’s correlation.Conclusions: Pretest and reliability has shown the questionnaire clear in wording and culturally appropriate. Process of translation and adaptation using Beaton’s procedure was user friendly, comprehensive and appears an essential method for translation of the questionnaire.

Abstract
In the current study, the Asinex and ChEBI databases were virtually screened for the identification of potential Lyn protein inhibitors. Therefore, a multi-steps molecular docking study was carried out using the VSW utility tool embedded in Maestro user interface of the Schrödinger suite. On initial screening, molecules having a higher XP-docking score and binding free energy compared to Staurosporin were considered for further assessment. Based on in silico pharmacokinetic analysis and a common-feature pharmacophore mapping model developed from the Staurosporin, four molecules were proposed as promising Lyn inhibitors. The binding interactions of all proposed Lyn inhibitors revealed strong ligand efficiency in terms of energy score obtained in molecular modelling analyses. Furthermore, the dynamic behaviour of each molecule in association with the Lyn protein-bound state was assessed through an all-atoms molecular dynamics (MD) simulation study. MD simulation analyses were confirmed with notable intermolecular interactions and consistent stability for the Lyn protein-ligand complexes throughout the simulation. High negative binding free energy of identified four compounds calculated through MM-PBSA approach demonstrated a strong binding affinity towards the Lyn protein. Hence, the proposed compounds might be taken forward as potential next-generation Lyn kinase inhibitors for managing numerous Lyn associated diseases or health complications after experimental validation.

Abstract
Standard mitral valve replacement in patients with chronic mitral valve regurgitation and mitral valve stenosis consistently results in a decrease in early postoperative left ventricular ejection performance. Some studies showed that preservation of mitral valve leaflet and subvalvular apparatus can reduce postoperative left ventricular dysfunction. On the basis of the concept, this randomized clinical trial comparing mitral valve replacement with preservation of mitral subvalvular apparatus and conventional mitral valve replacement performed in National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh, in the period of July 2010 to December 2011. We included 60 patients of mitral regurgitation and mitral stenosis, among them 30 patients underwent mitral valve replacement with preservation of mitral subvalvular apparatus (Group A) and 30 patients underwent conventional mitral valve replacement (Group B). There was no significant difference between two groups in terms of peri-operative variables. But there was significant higher incidence of Low cardiac output (LOS) syndrome [36.7% vs. 6.9% (p<0.05)] and congestive heart failure in Group B than Group A. The duration of ICU stay was also significantly higher in conventional mitral valve replacement group [113.23±11.30 hours vs. 96.23±20.02 (p=0.001)]. Additionally, there was significantly less fall of left ventricular ejection fraction in preservation of mitral subvalvular apparatus group [preop 65.27±5.45, at discharge 54.31±3.78, after 3 months 58.28±5.20 (p<0.0001)] than conventional group [preop 66.43±4.58, at discharge 46.43±3.87, after 3 months 46.55±3.63 (p<0.0001)]. In this study left ventricular ejection fraction was used as measure of left ventricular function. We postulate that, this relative preservation of left ventricular ejection fraction was likely the result of preservation of mitral subvalvular apparatus.

Abstract
The timing of eating, relative to when feed is offered, is affected by the social rank of feedlot cattle due to limited feed bunk space. As cattle can select feed based on dietary preference, the timing of eating for cattle in feedlot may be associated with the ingested diet composition. Our objectives were to determine the nutritive value and timing of feed ingested by 100 feedlot cattle during transition and the association of timing of eating with feeding behaviours and average daily gain (ADG). Cattle behaviour and timing of eating were determined on 100 feedlot cattle using accelerometer-based ear tag sensors from days 3 to 6 post feedlot induction (observation period), and the ongoing impact of this period on ADG was determined for the full feed period (75 days). To determine eating patterns at the time of feed offer, cattle were grouped according to the number of days they were recorded as eating within 1 h of feed being offered across 4 observation days, G0: not present across 4 days, G1: present for 1 day, G2: 2 days, G3: 3 days and G4: present for each of the 4 days. Total mixed ration (TMR) samples were collected for nutritive value analysis from four locations along the feed bunk from the time feed was offered and at hourly intervals thereafter for 7 h each day during the observation period. The composition of feed in the bunk changed across the 7 h of measurement (P < 0.05). The DM and CP of feed increased from 65 to 70% and 15 to 16%, respectively, and the NDF decreased from 36 to 32%. Thus, the preferred TMR feed component was the fibrous dietary fraction. However, the overall composition of the ingested diet for 7 h post feeding was similar between groups. Cattle in G0 had reduced eating time (0.7 vs 4.8%; P < 0.001), rumination time (4.5 vs 19.5%; P < 0.001) and ADG (1.0 vs 1.3 kg/d; P < 0.05) across the study, as compared with cattle in G4. Offering a more fibrous ration during feedlot transition, and customised cattle segregation and/or customised feeding regimes based on sensor derived feeding behaviour profiles during acclimation to feedlot can optimise ADG, animal welfare and feedlot profit.

Abstract
This study evaluates essential and toxic element contents in dragon (Hylocereus undatus (Haworth) Britton and Rose) and pomegranate (Punica granatum L.) and possible health risks through the consumption of these fruits. Total concentrations of 15 chemical elements (Al, Br, Ca, Cd, Cl, Cr, Cu, Fe, Hg, K, Mn, Na, Ni, Pb, and Zn) were determined by instrumental neutron activation analysis (INAA) and atomic absorption spectrometry (AAS) techniques. This study indicates that these fruits are a vital source of essential elements for human health. It is observed that Pb concentrations were higher in both fruits whereas Cd concentrations were slightly higher than WHO/FAO tolerable levels only in pomegranate. The estimated daily intake (EDI) of the chemical elements was within the maximum tolerable daily intake (MTDI) values. Furthermore, target hazard quotient (THQ) values were also within the safe level (THQ < 1). However, the calculated target carcinogenic risk (TCR) values of Cd for pomegranate and Cr for dragon fruit were higher than the maximum limit (1.0 × 10-4) for children. Finally, this study will create public awareness about micronutrient contents as well as metal contaminations of the studied fruits.

Abstract
INTRODUCTION Currently, there are several attempts to find an effective antiviral drugs against the COVID-19. Although majority of the COVID-19 patients have mild to moderate clinical events, up to 5-10% may have severe, life threatening events that urgently require effective drugs. The purpose of this systematic review is to evaluate the effectiveness of antiviral therapies in the treatment of COVID-19. METHODS An extensive search was performed in PubMed, EMBASE, Cochrane Library for randomised controlled trials (RCTs), prospective case series studies that evaluated therapies COVID-19. The outcomes searched for were mortality, recovery rate, length of hospital stay and clinical improvement from January to May 15, 2020. Independent reviewers searched, identified, screened, and related studies were included. RESULTS Total of five RCTs on 439 patients and seventeen case series involving 1656 patients were found in the specified review period that reported the use of Lopinavir, Ritonavir, Remdesivir. Oseltamivir, Ribavirin in patients with COVID-19; but none of which showed efficacy of antiviral therapy. Such current findings impede researchers from recommending an appropriate and effective antiviral therapy against COVID-19, making it a serious concern for the global community. DISCUSSION In the present pandemic and any future epidemics, all the related authorities should pursue many more RCTs, cohort and case series for a prospective outcome in the management and treatment guidelines.

Abstract
Femoral fractures are frequent in the pediatric population. Treatment options are based on the patient's age, fracture pattern, type of trauma and associated soft tissue injury. The traditional treatment method for pediatric femoral shaft fracture has been traction and spica casting. The immediate spica cast is safe and effective for children up to 6 years of age with isolated femoral fracture and acceptable reduction. Patients between 6 and 10 years of age can also be treated with spica casting with or without traction. This prospective study was done in the department of Orthopaedics, Mymensingh Medical College Hospital, Mymensingh, Bangladesh form from July 2015 to June 2019 to evaluate the outcome of closed reduction and internal fixation by titanium elastic nailing for fracture shaft of femur. Twenty patients, all presenting with fresh diaphyseal fractures of femur, treated with closed reduction and internal fixation by titanium elastic nailing. These patients were prospectively evaluated over a period of at least 18 months. Fractures were classified according to Association of Orthopaedics (AO) classification of shaft of femur fractures. According to AO classification, all were A1, A2, A3 fractures. Average age of the patients was 11±2.7 years; range was 6 to 16 years. There were 15 males and 5 females. Out of 20 cases treated with this method, stable fixation and union was achieved in all of them. Radiological union was achieved at an average of 10±2.3 weeks (8-15 weeks). The results were excellent in twelve patients (60%), successful in five (25%) and poor in three patients (15%) as per the scoring criteria for TEN. The effective treatment of diaphyseal fractures of the femur is intramedullary fixation by titanium elastic nailing in patients of the 6-16 years age group.

Abstract
More than 120,000 anterior cruciate ligament (ACL) injuries occur every year in the United States, mostly during the high school and college years. The incidence of these injuries is slowly increasing, especially in females. This is likely caused by their increasing participation in high school and other organized sports. In addition, several studies have shown that female athletes are at an increased risk of ACL injury in sex comparable sports. The goal of this study was to evaluate the functional outcome of Arthroscopic anterior cruciate ligament reconstruction using Bone-Patellar tendon- Bone autograft. 25 patients with chronic ACL deficient knee presenting to Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from January 2018 to December 2019 were included in the study. The patients with severe osteoarthritis (OA) knee, local active infection and systemic disease, intraarticular fracture of knee that might influence the study results were excluded from the study. Bone patellar tendon bone graft was harvested from ipsilateral knee. The patient was followed till 6 months with specified program of rehabilitation. Results were evaluated by an independent examiner using radiography, subjective and objective evaluation. Assessment using Lysholm's score was 50 (42-63) preoperatively and 90.8 (63-97) at the latest follow up (p<0.005). No patient complained of instability at latest follow up. The quadriceps muscle showed atrophy at final follow-up. Five Patients complained of anterior knee pain. We found no graft displacement on follow up radiographs. Osteo-integration occurred in all cases. ACLR with a BPTB graft can stabilize the knee without loss of motion by closely mimicking the native ACL without any hazards and additional complications. It is useful in high demand patients and cost effective option with high patient satisfaction rate for reconstruction of ACL.

Abstract
The Sundarbans is the only mangrove habitat in the world to support tigers Panthera tigris, whose persistence there is believed to be dependent on a very limited number of prey species. Conservation managers therefore need to understand how tigers utilise available prey species on a spatial scale in order to formulate a prey-based protection strategy for this global-priority tiger landscape. A total of 512 scat samples were collected during a survey of 1984 km2 of forest across 4 sample blocks in the 6017 km2 of the Bangladesh Sundarbans. Analysis of scat composition and prey remains reliably identified 5 major prey species, of which spotted deer Axis axis and wild pig Sus scrofa contributed a cumulative biomass of 89% to tiger diet. Tiger preference for prey species was highly skewed towards spotted deer and wild pig, but the relative contribution of these 2 species differed significantly across the 4 study areas, which spanned the Sundarbans, demonstrating important spatial patterns of tiger prey preference across the Sundarbans landscape. Given the comparatively limited number of prey species available to support the dwindling tiger population, different strategies are needed in different parts of the Sundarbans to support tiger populations and to protect spotted deer and wild pig populations from unabated poaching.

Abstract
The physical, psychological and financial burden of skin disease in low- to middle-income countries, where access to skincare is limited, is poorly understood. A group that we know very little about in this regard are refugees. There are limited data on the range of skin diseases and skincare needs of this group. To better understand the skincare needs of the displaced Rohingya population residing in the Kutupalong refugee camp, Bangladesh, we collected data on demographics, living conditions and range of dermatoses. In the 380 patients assessed, fungal skin infections, predominantly dermatophytes, were by far the most common skin disease seen (n = 215), followed by dermatitis (n = 81). Skin disease can be the presenting feature in many systemic conditions and may cause significant secondary complications itself. Developing a better understanding of the skincare needs of the refugee population is essential for future healthcare planning for this vulnerable group.

Abstract
The sudden outbreak of a novel coronavirus in 2019 in Wuhan, China, that rapidly provoked a global concern, marked as the third attack of corona virus in the human society that affected the global healthcare system as well as the global economy. Until and unless an effective vaccine is discovered against the virus, the pharmacological intervention by different antivirals is in the run for remedy. The aim of this systematic review was to evaluate the role of favipiravir along with its safety and efficacy for the patients who are suffering from severe acute respiratory distress syndrome due to CoronaVirus-2 (SARS-CoV-2) as re-purposeful use. We searched PubMed, EMBASE for randomized controlled trials (RCTs), cilicaltrial.com for registered on going trails to evaluate the pros and cons of using favipiravir in COVID-19. After vigorous searching, screening and sorting of 314 articles for completed and published scientific evidences in electronic database, there were only 2 completed and published randomized control trials (RCT) and 17 ongoing or unpublished trials found until June 2020. The main outcome measures were viral clearance, clinical improvement and adverse events reported and published on 147 patients infected with SARS-CoV2. The 2 completed RCTs showed significantly better treatment effects on disease progression, viral clearance, improved the latency to relief for pyrexia and cough on favipiravir treated patients. Adverse effects caused Favipiravir are mild and manageable. Although 9 more RCTs and cohort studies are supposed to be completed by this time that may unveil some evidence for use of anti-RNA-viral drug favipiravir against influenza or Ebola to re-purposing against COVID-19 as adopted in different treatment guidelines.

Abstract
Variety of conditions may be responsible for low back pain but lumber spinal canal stenosis is an important cause of low back pain. Lumber spinal canal stenosis usually presents with low backache with neurogenic claudication and shortness of walking distance in adult patient. Surgical management of lumbar spinal canal stenosis by decompression surgery is effective method. This prospective interventional study was performed in patient with clinical features like low back pain with radicular pain, neurogenic claudication, signs of root compression, positive MRI findings attending in department of Orthopaedic Surgery Mymensingh Medical College Hospital and Private Hospital from July 2016 to June 2019. Thirty patients were evaluated among those 20(66.6%) were 50 years and above. The mean age was 47.5±1.6 years. Male to female ratio was roughly 8:1. Almost all of the patients had low backache with radiation to the back of the thigh and leg with motor weakness (60%). About 66.6% of the patients had sensory deficit and 83.3% had neurogenic claudication. Majority (80.0%) of the patients at presentation had a suffering of 12 or >12 months. The mean duration of suffering was 14.7±5.1 months. About 55% of the patients were able to perform heel-walking and 36.0% tip-toe walking. Nearly 57% of the patients had sensory deficit along the distribution of 1st sacral nerve and 53.3% along the distribution of lumber 5 nerves. Diagnosis shows that 16.6% of patients had L4 lesion, 50% L5, 10.0% patients had L4 & L5 and 46.6% S1. Laminectomy was done in 26.6% of patients, laminectomy and disectomy in 33.3% and laminectomy, discectomy & foraminal decompression in 40.0% of patients. Twenty five (83.5%) of patients was free from symptoms. Eighty percent (80.0%) of patients shows minimal disability and 20.0% moderate disability on the basis of Oswestry Disability Index, while by MacNab criteria, most (80%) of patients was excellent, 10% good and another 10% fair. Repeated measure ANOVA statistics showed that mean Oswestry score decreased significantly from 54.5% at baseline to 22% at the end of 1 year (p<0.001).

Abstract
Chronic Obstructive Pulmonary disease (COPD) is a heterogenous respiratory disease characterized by a progressive, not fully reversible airflow limitation associated with an abnormal inflammatory response of the lung to noxious stimuli. It is a disease presenting with pulmonary inflammation as well as a systemic one. Measurement of inflammatory marker is difficult but platelet count estimation is easy and less costly. This descriptive, cross-sectional study was carried out at Department of Medicine, Mymensingh Medical college Hospital, Mymensingh, Bangladesh for a period of twelve months among fifty-nine COPD patients. Data were collected through interview, physical examination and laboratory investigations. Statistical analysis was performed using SPSS version 22.0 for consistency and completeness. Age range of the patients was 40 to 49 years with a mean of 56.3±10.9 years. Age group 40-49 years contained the highest number (19; 32.3%) of patients. Majority 57(96.6%) of the respondents were male. Thirty seven (62.7%) of patients were illiterate. Majority 56(94.9%) of patients resided in rural area, of them most 38(64.4%) were farmers. According to Spirometric measurement among 59 respondents of COPD patient, 3(5.1%) were in GOLD stage-I, 9(15.3%) in GOLD stage-II, 27(45.8%) in GOLD stage-III and 20(33.9%) in GOLD stage IV group. Mean platelet count (10³/μl), 241.6±86.5 was found in mild, whereas 315.0±47.7 in moderate, 337.2±76.3 in severe, and 412.4±67.5 in very severe group of COPD patients. So increase in platelet count is statistically significant in severity of COPD. In conclusion, platelet count measurement is less costly to categorize COPD and may be a diagnostic marker.

Abstract
Protocols for assessing the welfare of dairy cows in large scale intensive dairy systems in the developed world have been used extensively. Little attention has been paid to the use of similar welfare assessment protocols for small dairy enterprises in developing countries. We modified part of the standard assessment protocol and used it to assess aspects of the welfare of dairy cows in a field survey of 70 small farms in the Sirajgonj district of Bangladesh. Welfare indicators selected were mainly those of health and economic importance, such as lameness, lesions on the body and limbs, cleanliness levels, milk yield, and body condition. The study included physical examination of 700 cows and use of a structured questionnaire to collect data on health and management practices and farmers' perspectives about animal welfare. Mean milk yield, averaged across farms, was 10.3 L/d (range 6.3-14.2) and body condition assessment indicated that cows were, on average, thin. Hygiene management was often poor, with soiling of body parts with faeces. The prevalence of lameness, at 4.3%, was less than has commonly been observed in larger, more intensive dairy farms, but body injuries were commonly detected at the carpal and hock joints (56 and 51% of cows, respectively). This suggests that floors and/or bedding to lie on were inadequate. Many farmers did not follow routine vaccination and deworming schedules (63% and 31%, respectively) and farmers were not generally aware of the concept of animal welfare. The study demonstrates some similar welfare issues to those that have been commonly identified in large, intensive units, but also some differences, in particular a failure to provide good floors, bedding, and basic health care.

Abstract
BACKGROUND: The study was conducted in BRAC-administered areas of the Bangladesh National Tuberculosis (TB) Programme (42 of 64 districts). According to the 2013-2017 financial support scheme, direct costs due to TB diagnosis were reimbursed among economically disadvantaged people with presumptive smear-negative pulmonary (PTB) and extrapulmonary TB (EPTB).OBJECTIVE: To describe the implementation of the scheme and associated changes in case notification.DESIGN: This was a descriptive study involving programme data.RESULTS: Between 2013 and 2017, persons reimbursed reduced from 125 680 to 88 763, and the case detection ratio increased from 18% to 24%. The number of patients with presumptive EPTB who were reimbursed decreased from 5024 to 3484. More than 95% were reimbursed for chest radiograph, fine-needle aspiration cytology and biopsy. However, large numbers of ancillary investigations were also reimbursed. During 2013-2017, the observed national quarterly new smear-negative PTB case notification rates (CNRs) were significantly higher than the forecasted CNRs (based on CNR trends during 2008-2012). New EPTB and all form TB CNRs increased but not significantly.CONCLUSION: Implementation of the financial support scheme was accompanied by a significant improvement in new, smear-negative PTB notification. The absence of a comparison arm was a key limitation, but comparison was not possible as the scheme was implemented in all districts.

Abstract
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
Bone marrow is a source of osteoprogenitor cells which are the most important factor of bone formation and healing of fracture. The aim of the study is to evaluate the outcome of bone marrow injection in the management of delayed union and non-union. This prospective study was performed in the department of Orthopaedics, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2017 to June 2019. In this study 21 patients with delayed union and non-union were treated by bone marrow injection. Bone marrow were aspirated from the anterior or posterior iliac crests then injected percutaneously into the fracture site. Full union was achieved in 15 cases, while failed in the others. No major complications were seen during or after the procedure. It is a safe, easy and a minimally invasive procedure compared to usual open bone graft especially for cases with high risk of anesthesia or risk of infection.

Abstract
Pregnancy is accompanied by changes in the maternal lipoprotein metabolism that may serve to satisfy the nutritional demands of the fetus in addition to the energy requirements of the mother. Early pregnancy is considered the anabolic phase, characterized by increased hepatic production of triglycerides and enhanced removal of triglycerides from the circulation, resulting in an increased deposition of fat in maternal adipose tissue. Late pregnancy is referred to as the catabolic phase, the release of free fatty acids from adipocytes is enhanced due to both relative insulin resistance and stimulation of hormones. Although it is known that cholesterol rises in pregnancy, at present it is not routinely measured or treated. However, a growing body of evidence from animal and human studies suggests adverse consequences of high cholesterol levels in pregnancy. High lipid profile, a major factor behind atherosclerosis may leads to unconsciousness. To avoid such problems during pregnancy this longitudinal study was carried out in the department of Biochemistry, Mymensingh Medical College in co-operation with the Department of Obstetrics and Gynecology, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh from July 2011 to December 2012 to compare the changes in high density lipoprotein cholesterol level during 2nd and 3rd trimester of pregnancy. A total of one hundred subjects were participated in this study comprising of second and third trimester of pregnancy. All subjects were made to fast overnight at least for a minimum of 8 hours. Blood samples were taken and analyzed by enzymatic colorimetric kit method. Pregnancy has been found to be associated with changes in lipid profile and this differs with each trimester. The average results were analyzed with respect to each pregnancy for the whole group. The study proves that serum High Density Lipoprotein (HDL) cholesterol increases in second trimester (48.71±7.61mg/dl) than third trimester (47.01±7.45mg/dl) of Pregnancy. So, Lipid profile estimation and monitoring should be made as a part of routine investigation during antenatal period.

Abstract
Pervasive salinity in soil and water is affecting agricultural yield and the health of millions of delta dwellers in Asia. This is also being exacerbated by climate change through increases in sea level and tropical storm surges. One consequence of this has been a widespread introduction of salt water shrimp farming. Here, we show, using field data and modeling, how changes in climate and land use are likely to result in increased salinization of shallow groundwater in SE Asian mega-deltas. We also explore possible adaptation options. We find that possible future increase of episodic inundation events, combined with salt water shrimp farming, will cause rapid salinization of groundwater in the region making it less suitable for drinking water and irrigation. However, modified land use and water management practices can mitigate the impacts on groundwater, as well as the overlying soil, from future salinization. The study therefore provides guidance for adaptation planning to reduce future salinization in Asian deltas.

Abstract
The objective of the study was to find out the prevalence of gallbladder carcinoma in patients having cholelithiasis. For this purpose a prospective study was carried out on 15 patients of both sexes in Shaheed Ziaur Rahman Medical College Hospital, Bogura. Their mean age was 56 ±8 years (range 30 to 70 years) having gall bladder mass. Gall bladder mass and stone were detected by history, Physical examination, ultrasonography and computed tomography of the abdomen. Carcinoma was confirmed by histopathological examination of specimens removed by operation. All gallbladder masses removed by operation showed malignat tumor on histopathological examination. Among them adenocarcinoma and squamous cell carcinoma were present in 94 and 6 percent respectively. Stones were present within gallbladder mass in 94 percent of cases. In 80 percent of cases the disease was in advanced stage. The results of the present study suggested that the patient having cholelithiasis are prone to develop malignancy in the gallbladder. However as the sample size is small further studies are needed by taking large number of sample to validate this statement
