Abstract
Self- rated health (SRH) is a valuable screening-level measure of a community's health status. A better understanding of the factors that influence SRH is time-demanding and challenging. This study aims to examine the determinants of SRH by investigating health morbidities, demographic and socio-economic factors in Bangladesh perspective. This cross-sectional study was conducted among 908 adults (aged 18 years and above) in Manikganj district of central Bangladesh from 2nd January to 13th January 2017. Chi-square test was performed to test the association and binary logistic regression was performed to predict the relationship of SRH with all potential variables. The present study reveals the balance of bad health versus good health which was 27.2% and 72.8% respectively. Participants had at least one or more chronic diseases reported 3.40 times (p<0.001) bad health compared to those who did not have any chronic illness. In contrast, acute morbidity was not a significant determinant for SRH (OR=1.379, p=0.063). Older population aged 60 years and above had 3.96 times (p<0.001) higher chance of having self-reported bad health than the younger population. In addition, depression was also found a significant contributor (OR=2.05, p<0.001) to bad health. Chronic morbidity, older age and depression are the significant predictors of SRH. If SRH is used as a screening-level measure for the rural communities then the chronic disease status of rural Bangladesh will be identified quickly and easily.

Abstract
The level of thyroid hormones is often changed in uncontrolled diabetic patients. Screening for Thyroid dysfunction (TD) among patients with Type 2 Diabetes mellitus (T2DM) should be performed considering the increased prevalence of thyroid disorders. This cross-sectional comparative study was conducted in outpatient department of Endocrinology and Medicine, Mymensingh Medical College Hospital, Mymensingh (MMCH) from 1st March 2020 to 30th August 2021. One hundred (100) patients with type 2 diabetes along with 100 (hundred) non-diabetic controls of same age group were enrolled in the study. After taking clinical data, patients were investigated to estimate Fasting plasma glucose (FPG), serum free tri-iodothyronine (FT3), free thyroxin (FT4) and thyroid stimulating hormone (TSH) level to see thyroid dysfunction. Patients were selected with purposive sampling. Thyroid dysfunction was found to be more in T2DM (15.0%) in comparison with non-diabetic controls (5.0%) and this difference was statistically significant (p=0.018). In both diabetic and non-diabetic groups, subclinical hypothyroidism and hypothyroidism were the most common thyroid dysfunction. Thyroid dysfunction was found more in 40-60 years that suggests the prevalence of thyroid dysfunction are increasing in diabetic patients with advancing age. Thyroid dysfunction was found more among overweight and obese patient in both groups. Mean BMI was found higher among diabetic patient with thyroid dysfunction. Logistic regression showed significant association of Thyroid dysfunction with age >50 years and high FPG level. We found thyroid dysfunction was more prevalent in patients with T2DM than non-diabetics. So, screening for thyroid dysfunction among type 2 diabetic patients by estimating Serum TSH, FT4 level should be performed.

Abstract
Previously, we have developed DynamicMC for modeling relative movement of Oak Ridge National Laboratory phantom in a radiation field for the Monte Carlo N-Particle package (Health Physics. 2023,124(4):301-309). Using this software, three-dimensional dose distributions in a phantom irradiated by a certain mono-energetic (Mono E) source can be deduced through its graphical user interface. In this study, we extended DynamicMC to be used in combination with the Particle and Heavy Ion Transport code System (PHITS) by providing it with a higher flexibility for dynamic movement for an anthropomorphic phantom. For this purpose, we implemented four new functions into the software, which are (1) to generate not only Mono E sources but also those having an energy spectrum of an arbitrary radioisotope (2) to calculate the absorbed doses for several radiologically important organs (3) to automatically average the calculated absorbed doses along the path of the phantom and (4) to generate user-defined slab shielding materials. The first and third items utilize the PHITS-specific modalities named radioisotope-source and sumtally functions, respectively. The computational cost and complexity can be dramatically reduced with these features. We anticipate that the present work and the developed open-source tools will be in the interest of nuclear radiation physics community for research and teaching purposes.

Abstract
Background and Aim Campylobacter infections in sheep may be asymptomatic or cause enteritis, ileitis, infertility, and abortion. Thus, this study aimed to estimate the prevalence of Campylobacter spp. in farming sheep and to detect risk factors, molecular patterns, and antimicrobial susceptibility status of these pathogens. Materials and Methods Four hundred and eight fecal samples were collected from 12 flocks in the Mymensingh and Sherpur districts. Samples were tested by both basic (culture and biochemical tests) and molecular (initially 16S rRNA and later hipO gene-based polymerase chain reaction). Furthermore, the antimicrobial susceptibility status of Campylobacter jejuni was confirmed using disk diffusion. Flock- and animal-level data were captured using semi-structured interviews with farm owners under bivariate and multivariate logistic regression analyses to confirm the risk factors for Campylobacter-positive status. Results The prevalence of C. jejuni staining at the animal and flock levels was 8.82% (36/408) and 66.70% (8/12), respectively. The age of sheep was identified as an important risk factor. Up to 1 year of age, sheep were 3.78 times more likely to be infected with C. jejuni (95% confidence interval: 1.0736-13.3146, p = 0.038). Of the 36 isolates of C. jejuni, all were found to be fully susceptible (100%) to gentamicin and ciprofloxacin. In this study, three antimicrobial agents, oxytetracycline, azithromycin, and ceftriaxone, were fully resistant (100%). The majority of isolates were resistant to a combination of 4-6 antimicrobial agents. Conclusion The present study highlights the predominant maintenance of zoonotic Campylobacter species in sheep, and their burden on human health is enormous. Therefore, environmental, animal, and human health needs to be focused under a One Health lens to mitigate the occurrence of Campylobacter in farm settings and to prevent further introduction to animals and humans.

Abstract
SARS COV 2 raised immense agony to everyone. As health care workers remains direct contact with patients, they are vulnerable to mental health disorder. The study was done to identify mental health status of health care providers of Bangladesh. It was a cross sectional web based survey among health care providers of bangladesh. A structured web based questionnaire was prepared both in Bangla and English version for better understanding. Total 2594 health care workers responded to online survey. Male were 1303(50.2%) and female were 1291(49.8%). Occupational demography shows 98.5% were physicians. Mean value of patient health questionnaire 9 (PHQ9) and generalized anxiety disorder (GAD) were 8.43±6.082 and 8.27±5.234 respectively among healthcare providers. To overcome anxiety and depression, 93.4% of HCW didn't receive any psychological material and 85.6% HCW didn't find physiological resources even through media. Despite many lacking, healthcare workers were resilient in our study.

Abstract
The experiment was conducted at the research field, Department of Agronomy, Hajee Mohammad Danesh Science and Technology University, Dinajpur from December 2017 to May 2018 to find out the best treatment of foliar application of urea on the growth and yield of boro rice cv. BRRI dhan28. The experiment consisted of 10 treatments, laid out in a randomized complete block design in triplicate. The recommended doses (RD) of urea, TSP, MOP, gypsum, ZnSO4, and borax were applied during land preparation except for urea at 250, 75, 100, 75, 7, and 5 kg ha-1, respectively, where urea was applied as per treatment specification. The results revealed that the application of N fertilizer as foliage along with soil significantly influenced the growth, plant characteristics, and yield of BRRI dhan28. There was no significant difference between T8 (70% in soil and 10% as foliage) and T9 (100% in soil) treatment regarding the maximum panicle length (21.43 and 20.71 cm), fertile grains (117.40 and 113.30), total grains (134.40 and 130.97), 1000-grain weight (24.56 and 23.56 g), grain yield (5.91 and 5.74 t ha-1), straw yield (7.83 and 7.92 t ha-1), biological yield (13.74 and 13.66 t ha-1), and harvest index (43.01 and 42.02%), respectively, in this study. These results indicated that N fertilization as direct soil application (70%) and as foliage application (10%), i.e., 80% N fertilization, produced the highest grain yield and major yield traits which we received by 100% N fertilization as soil that was practiced traditionally by the farmers. The effect of overfertilization (T10) was not positive, producing the highest number of noneffective tillers and sterile grains (nonfilled grains). Therefore, it is possible to achieve an equivalent or more yield by saving 20% urea by the combination of soil (70%) and foliage (10%) application as compared to the traditional method of fertilizer application (100% in soil).

Abstract
This study was conducted to develop a cell culture based PPR virus vaccine candidate using recent Bangladeshi strain of peste des petits ruminant's (PPR) virus. PPR virus was isolated from field outbreaks, confirmed by RT-PCR and used as viral inoculum for serial passaging in Vero cells for adaptation and attenuation. 60th serial passage had completed and RT-PCR and real time RT-PCR were done in every 5 passages for confirmation of PPR virus in tissue culture fluid (TCF). To assess the adaptation and attenuation cytopathology, virus titration, sequencing of both F and N genes and live animal experimentation were done. Different cellular alterations produced by PPR virus in infected Vero cells including syncytia formation, development of both intranuclear and intra cytoplasmic inclusion bodies and finally cell degradation are the indications of adaptation. The virus titre was found 2.5, 3.31, 3.55, 4.44, 4.71 and 6.5 Log10 TCID50/ml at 10th, 20th, 30th, 40th, 50th and 60th passages level respectively. In F gene sequence analysis it has been observed that few nucleotide (nt) and mino acid (aa) has been substituted as the effects of serial passaging of PPR virus in Vero cells. TCF at 60th passage level was found effective to produced protective antibody (Ab) titre in live animal experimentation. It is concluded that serially passaged and Vero cells adapted PPR virus TCF could be used as a vaccine candidate for further use to develop a potent & effective vaccine against PPR diseases.

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
OBJECTIVES We aimed to determine: (1) the prevalence and socio-economic distribution of undiagnosed, untreated, and uncontrolled diabetes mellitus (DM); (2) the relationship between socio-economic status (SES) and undiagnosed, untreated, and uncontrolled DM; and (3) if this relationship is mediated by gender. STUDY DESIGN Cross-sectional nationally representative household-based survey. METHODS We used data from the Bangladesh Demographic Health Survey from 2017 to 18. Our findings were based on the responses of 12,144 individuals aged 18 years and older. As a measure of SES, we focused on standard of living (hereinafter referred to as wealth). The study's outcome variables were prevalence of total (diagnosed + undiagnosed), undiagnosed, untreated, and uncontrolled DM. We used three regression-based approaches-adjusted odds ratio, relative inequality index, and slope inequality index-to assess different aspects of SES differences in the prevalence of total, undiagnosed, untreated, and uncontrolled DM. We used logistic regression analysis to look at the adjusted association between SES and the outcomes after gender stratification to see whether gender status moderates the association between SES and the targeted outcomes. RESULTS In our sample analysis, the age-adjusted prevalence of total, undiagnosed, untreated, and uncontrolled DM was 9.1%, 61.4%, 64.7%, and 72.1%, respectively. Females had a higher prevalence of DM and undiagnosed, untreated, and uncontrolled DM than males. When compared to people in the poor SES group, people in the rich and middle SES groups had 2.60 times (95% confidence interval [CI] 2.05-3.29) and 1.47 times (95% CI 1.18-1.83) higher chance of developing DM. When compared to individuals in the poor SES group, those in the rich SES groups were 0.50 (95% CI 0.33-0.77) and 0.55 times (95% CI 0.36-0.85) less likely to have undiagnosed and untreated DM. CONCLUSIONS In Bangladesh, rich SES groups were more likely than poor SES groups to have DM, whereas poor SES groups with DM were less likely than rich SES groups to be aware of their disease and obtain treatment. The government and other concerned parties are urged by this study to pay more attention to developing suitable policy measures to reduce the risk of DM, particularly among rich SES groups, as well as targeted efforts to screen for and diagnose DM in socio-economically disadvantaged groups.

Abstract
In Bangladesh most agronomic biomass (straw, husk, dried dung) is burnt for domestic cooking use. Consequently, the soil is continuously stripped of mineral nutrients and carbon (C) substrate. Here we investigate if recycling of household ash (ash) as fertilizer can sustainably improve soil fertility as well as minimise accumulation of toxic elements (As, Cd) in rice grain. Large scale field trials across two geographic regions (Barind, Madhupur) and two seasons (wet, dry) and with application of 3 fertiliser treatments (NPKS, ash, NPKS + ash) were conducted. At the end of each season, the impact of region*season*treatment on soil microbial comunities, rice yield, and grain quality (As, Cd, nutrient elements) was assessed. When compared to conventional field application rates of NPKS (control), application of ash boosted rice yield by circa. 20% in both regions during wet and dry season, with no effect on rice grain carcinogenic inorganic arsenic (iAs), dimethylarsonic acid (DMA) or cadmium (Cd), but with potential to increase zinc (Zn). For soil microbial communities, a significant region and season effect as well as correlation with elements in rice grain was observed, amongst these Cd, Zn, iAs and DMA. This study illustrates that application of ash can reduce the requirement for expensive chemical fertiliser, whilst at the same time increasing rice yield and maintaining grain quality, making farming in Bangladesh more sustainable and productive. The study also implies that the combined impact of region, season, and soil microbes determines accumulation of elements in rice grain.

Abstract
Acute myocardial infarction (AMI) patients characterize a large proportion of admissions in coronary care unit and their management and risk stratification is of immense importance. Hypomagnesemia is a long-term risk factor for incident of both myocardial infarction and arrhythmia. We assessed whether serum magnesium levels at admission is associated with arrhythmias and in-hospital mortality in patients with acute myocardial infarction (AMI). The aim of the study was to evaluate the prognostic implications of serum magnesium level in patients with acute myocardial infarction. This cross-sectional observational study was conducted in the department of cardiology in Mymensingh Medical College Hospital from October 2017 to March 2019. Total 259 acute myocardial infarction patients were included considering inclusion and exclusion criteria. The sample population was divided into two groups: Group-I: Patients with acute myocardial infarction with serum magnesium ≥1.82mg/dl. Group-II: Patients with acute myocardial infarction with serum magnesium <1.82mg/dl. Serum magnesium level was measured on admission, and the incidence of in-hospital major cardiac events was assessed. In this study mean serum magnesium level of Group-I, Group-II were 2.21±0.14mg/dl, 1.60±0.15mg/dl respectively. It was statistically significant (p<0.05). In-hospital outcomes of the study group revealed that low risk group patients were uneventful outcome during hospitalization period, they had no any complication. In Group-I patient, 9(4.8%) were developed arrhythmias, 26(13.9%) were developed heart failure, 9(4.8%) were developed cardiogenic shock and 3(1.6%) were died and in Group-II patient, 44(61.10%) developed arrhythmias, 9(12.50%) were developed heart failure, 7(9.7%) were developed cardiogenic shock and 12(16.7%) were died out of them which was statistically significant (p<0.05). Mean duration of hospital stay of the study population according serum magnesium level was in Group-I, 4.27±0.68 days, in Group-II, 5.84±1.05 days which was statistically significant (p<0.05). In conclusion patient with serum magnesium level less than 1.82mg/dl increased the risk of in-hospital arrhythmia and death.

Abstract
The present work introduced a framework to investigate the effectiveness of proton boron fusion therapy (PBFT) at the cellular level. The framework consisted of a cell array generator program coupled with PHITS Monte Carlo package with a dedicated terminal-based code editor that was developed in this work. The framework enabled users to model large cell arrays with normal, all boron, and random boron filled cytoplasm, to investigate the underlying mechanism of PBFT. It was found that alpha particles and neutrons could be produced in absence of boron mainly because of nuclear reaction induced by proton interaction with 16O, 12C and 14N nuclei. The effectiveness of PBFT is highly dependent on the incident proton energy, source size, cell array size, buffer medium thickness layer, concentration and distribution of boron in the cell array. To quantitatively assess the effectiveness of PBFT, of the total energy deposition by alpha particle for different cases were determined. The number of alpha particle hits in cell cytoplasm and nucleus for normal and 100 ppm boron were determined. The obtained results and the developed tools would be useful for future development of PBFT to objectively determine the effectiveness of this treatment modality.

Abstract
Increase platelet count can accompany various cancers including lung cancer. This finding has recently been suggested to indicate poor prognosis. In patients with malignancies, thrombocytosis has previously been related disease stage, histological type and survival. In this study, the prevalence of thrombocytosis and the prognostic information provided by platelet count were analyzed in patients with stage IV Non-Small Cell Lung Cancer (NSCLC) with an aim to assess elevated platelet count as a prognostic factor in patients with stage IV NSCLC and to investigate whether there is relationship between thrombocytosis, other clinico-pathologic factors and median survival. This prospective observational study was conducted in National Institute of Cancer Research and Hospital (NICRH), Dhaka, Bangladesh from September 2019 to August 2020. A total of 108 patients were enrolled purposively. Detail history taking, thorough physical examination was done along with relevant investigations. Data were collected by semi structured questionnaire and analysis was done with the help of Statistical Package for Social Science (SPSS), version 21.0. The mean age of the patients was found 56.4±12.2 years with range from 35 to 75 years. Majority (79.6%) patients were male, 52.8% patients came from low income and 36.1% were farmer. Majority (40.7%) were symptomatic; in bed >50.0% of day. Almost two third (59.3%) had <5.0% weight loss. Almost three fourth (69.4%) had squamous cell carcinoma. At the time of first assessment 75(69.4%) patients had normal and 33(30.6%) had elevated platelet count level. Age, sex and histological type were statistically not significant between normal and elevated platelet count level groups. But performance status, weight loss were statistically significant (p<0.05) between two groups. According to univariate analysis, age, performance status at presentation, weight loss more than 10.0% for 3 months and platelet count prior the start of treatment were all significant predictors for the overall survival. In multivariate analysis age, performance status at presentation and initial thrombocytosis were independent prognostic determinants for overall survival. Median survival time was significantly higher for the normal platelet count group and elevated platelet count group (7.5 months versus 5.5 months) respectively (95% CI, 5.5-7.5), p<0.001. The frequency of thrombocytosis in patients with stage-IV NSCLC at first presentation was 30.6% and median survival time in these patients was significantly shorter compared in patients without thrombocytosis. These results concluded that an elevated platelet count could be a useful prognostic factor for survival in patients with stage-IV NSCLC.

Abstract
Patients with HIV or AIDS suffer from wide varieties of complications that are related to infection. The eye as an organ is not spared from HIV-related manifestations. The ocular manifestations can be the presenting sign of a systemic infection in an otherwise asymptomatic HIV-positive person. The disease can have adnexal, anterior segment, posterior segment, orbital and neuro-ophthalmic manifestations. The objective of the study was to evaluate the ophthalmological manifestations among adult HIV infected patients of Bangladesh and co-relate the findings with CD-4+ T cell count. This cross sectional study was conducted in the department of Community Ophthalmology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from January 2013 to September 2015. Purposive sampling technique was applied to enroll the patients. Total 110 patients were enrolled regardless of their immunological status by inclusion and exclusion criteria. Relevant clinical evaluation including history & physical examinations, laboratory investigations and some ocular examinations like- visual acuity, slit lamp biomicroscopy, IOP, indirect ophthalmoscopy with +90D (diopter) and +20D were done. The age of the study population ranged from 20-58 years with mean±SD 37.63±8.16 years. Among the study population 67(60.9%) were male and 43(39.1%) were female. According to ART status, 58(52.7%) were on ART and 52(47.3%) were ART naive. The mean CD4+ T- cells count was 410±281.65 with minimum to maximum was 6-1266 cells/μl. Among them 53(48.2%) had HIV related ocular findings and 57(51.8%) had no HIV related ocular manifestation. In relation with CD+ T- cells count, highly significant relation was found with lower CD4+ T- cells count and ocular manifestation (p=0.001).

Abstract
The interaction of ionizing radiation with matter is a stochastic process and statistical analysis of such a process would be a crucial step in understanding radioactivity. Geiger–Müller (GM) counter is a widely used radiation detector used in nuclear radiation surveying, which produces counts upon exposure to a radioactive source. There are a variety of multi-purpose software that can be used to perform statistical analysis of measured counts from a GM counter. However, statistical analysis is a lengthy, error prone and time-consuming process, which gets more tedious when the number of measurements increases. In the present work, we have developed an open-source and easy-to-use graphical user interface (GUI) computer program named RadStat for statistical analysis of counts measured by a GM counter. RadStat has its own scripting syntaxes and bundled with gnuplot for quick visualization of output results. We believe the present open-source GUI program would be a useful tool for research and teaching of nuclear radiation physics.

Abstract
The Monte Carlo (MC) method is a powerful tool for modeling nuclear radiation interaction with matter. A variety of MC software packages has been developed, especially for applications in radiation therapy. Most widely used MC packages require users to write their own input scripts for their systems, which can be a time consuming and error prone process and requires extensive user experience. In the present work, we have developed a graphical user interface (GUI) bundled with a custom-made 3D OpenGL visualizer for PHITS MC package. The current version focuses on modeling proton induced positron emitting radioisotopes, which in turn can be used for verification of proton ranges in proton therapy. The developed GUI program does not require extensive user experience. The present open-source program is distributed under GPLv3 license that allows users to freely download, modify, recompile and redistribute the program.

Abstract
Thyroid swellings are common clinical problem throughout the world and also in Bangladesh. Most of thyroid swellings are multinodular, but a good percentage is solitary thyroid nodule. There is no robust, feasible method for malignancy differentiation has not been well established. The study evaluated thyroid nodules for risk of malignancy and compared history, clinical, sonographic features and FNAC findings with histopathology. This was a cross sectional study on 160 consecutive subjects of thyroid nodules done in the department of ENT and Head Neck Surgery of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh during from July 2018 to December 2019. All patients were admitted and diagnosed by detail history, clinical examination, investigations and underwent thyroidectomy. Detailed history, clinical examination, ultrasonographic finding and FNAC variables were documented retrospectively and a mathematical model was established for malignancy prediction. In this study mean age of the patients of thyroid nodules was 37.54±11.49 years and majority of the patients were within 21-40 years of age. Frequency of thyroid nodules is more in female with male female ratio 1:7. Most of the thyroid nodules appeared in this study within 0-2 years (61.9%). In this series of thyroid nodules constituted 88.1% firm, 8.8% hard, 3.1% cystic. Among the patients 89(55.6%) cases have solitary thyroid nodule and 71(44.4%) cases have multinodular goitre Majority of the nodules were warm 57.5% followed by cold 42.5%. FNAC showed nodular goitre 72.5%, Follicular neoplasm 1.3%, Papillary carcinoma of thyroid 7.5%, colloid goitre 9.4%, suspicious papillary carcinoma 3.8% and lymphocytic thyroiditis 1.3%. In this study out of 85 solid nodule, 69(81.18%) were benign and 16(18.82%) was malignant and out of 3 cystic nodule 3(100%) were benign. In this study most of the benign and malignant nodules were predominantly solid. Study showed the malignancy is significantly (p=0.001) more in solid than cystic nodules. Final diagnosis in this study was done on the basis of histopathological reports. Out of 160 patients, histopathologically benign lesion was 120(75%) and malignant was 40(25%). Among malignant cases 36(22.5%) cases were papillary carcinoma, 1 case was medullary carcinoma and 3 cases were follicular carcinoma.

Abstract
The Monte Carlo method is employed in this study to simulate the proton irradiation of a water-gel phantom. Positron-emitting radionuclides such as 11C, 15O, and 13N are scored using the Particle and Heavy Ion Transport Code System Monte Carlo code package. Previously, it was reported that as a result of 16O(p,2p2n)13N nuclear reaction, whose threshold energy is relatively low (5.660 MeV), a 13N peak is formed near the actual Bragg peak. Considering the generated 13N peak, we obtain offset distance values between the 13N peak and the actual Bragg peak for various incident proton energies ranging from 45 to 250 MeV, with an energy interval of 5 MeV. The offset distances fluctuate between 1.0 and 2.0 mm. For example, the offset distances between the 13N peak and the Bragg peak are 2.0, 2.0, and 1.0 mm for incident proton energies of 80, 160, and 240 MeV, respectively. These slight fluctuations for different incident proton energies are due to the relatively stable energy-dependent cross-section data for the 16O(p,2p2n)13N nuclear reaction. Hence, we develop an open-source computer program that performs linear and non-linear interpolations of offset distance data against the incident proton energy, which further reduces the energy interval from 5 to 0.1 MeV. In addition, we perform spectral analysis to reconstruct the 13N Bragg peak, and the results are consistent with those predicted from Monte Carlo computations. Hence, the results are used to generate three-dimensional scatter plots of the 13N radionuclide distribution in the modeled phantom. The obtained results and the developed methodologies will facilitate future investigations into proton range monitoring for therapeutic applications.

Abstract
BACKGROUND Mungbean (Vigna radiata L. Wilczek) is one of the most important pulse crops, well-known for its protein-rich seeds. Growth and productivity are severely undermined by waterlogging. METHODS In this study, we aim to evaluate how two promising phytohormones, namely cytokinin (CK) and gibberellic acid (GA3), can improve waterlogging tolerance in mungbean by investigating key morphological, physiological, biochemical, and yield-related attributes. RESULTS Our results showed that foliar application of CK and GA3 under 5-day of waterlogged conditions improved mungbean growth and biomass, which was associated with increased levels of photosynthetic rate and pigments. Waterlogged-induced accumulation of reactive oxygen species and the consequently elevated levels of malondialdehyde were considerably reduced by CK and GA3 treatments. Mungbean plants sprayed with either CK or GA3 suffered less oxidative stress due to the enhancement of total phenolics and flavonoids levels. Improvement in the contents of proline and total soluble sugars indicated a better osmotic adjustment following CK and GA3 treatments in waterlogged-exposed plants. Most fundamentally, CK or GA3-sprayed waterlogged-stressed mungbean plants demonstrated better performance in the aforementioned parameters after the 15-day recovery period as compared to water-sprayed waterlogged-exposed plants. Our results also revealed that CK and GA3 treatments increased yield-associated features in the waterlogged-stressed plant. Here, both phytohormones are efficient in improving mungbean resistance to waterlogging. However, CK was found to be more effective. Overall, our findings suggested that CK or GA3 could be used for managing waterlogging-induced damage to mungbean and perhaps in other cash crops.

Abstract
Rapid spread of multidrug resistant microorganisms is a matter of great concern throughout the glove including Bangladesh. The objective was to identify the causative organisms for urinary tract infection (UTI) and their sensitivity patterns to antibiotics. This descriptive cross-sectional study was conducted on patients admitted with UTI (n=60) at a tertiary level hospital in Dhaka, Bangladesh from March 2019 to September 2019. Data were collected through clinical record reviews. Data of all these 60 cases were analyzed for socio-demographic characteristics. Of the 60 patients, culture and sensitivity report was available for 42 patients. Therefore, data were further analyzed for these 42 cases. Median age of patients was 35 years and 80% were female. The main organisms isolated from urine culture of UTI patients were E. coli (64%), Klebsiella (12%) and Enterococci species (10%). Susceptibility to antibiotics was analyzed only for E. coli (n=27) since the number of isolates of other organisms were small. E. coli was found to be resistant to most of the first- and second-line antibiotics, such as Amoxicillin (100%), Amoxyclav (72%), Co-trimoxazole (89%), Nalidixic acid (78%), Ceftazidim (94%), Ceftriaxone (73%), Cefuroxime (100%), Ciprofloxacin (59%), Cephotaxime (80%), Cefixime (100%) and Moxifloxacin (100%). E. coli was the predominant organism responsible for UTI and was resistant to most of the first- and second-line antibiotics. Immediate action is needed to develop empirical guideline for empirical management of UTI and establish surveillance system for monitoring.

Abstract
Low-income countries (LICs) and lower-middle-income countries (LMICs) are still deprived of the optimum doses of coronavirus disease 2019 (COVID-19) vaccines for their population, equal access and distribution, as well as mass immunization roadmaps to be implemented for achieving herd immunity and protection from the ongoing pandemic. In this short report, we are interacting with the world public health experts, as well as national and global leaders for warranting the mass vaccination drive to be more progressive against COVID-19 with equitable access of vaccines to LICs or LMICs to save the lives of the poorest country people and refugees. From several scientific databases, such as Google Scholar, PubMed, as well as national and international news websites, the data were collected data by utilizing appropriate keywords regarding the topic. Bangladesh might be exemplified in this brief communication as the representative of LMIC. As of October 14, 2021, 48% of the world's people have received at least one dose of the COVID-19 vaccine. In contrast, only 2.5% of people from LICs have come in under COVID-19 vaccination for at least a single shot. Both LICs and LMICs need far more vision and ambition, including political, administrative, and diplomatic progress along with enhancing the vaccination drive for their population to be immunized through simultaneous mass vaccination progress of other countries with implementing public health safety measures against the COVID-19 pandemic.

Abstract
High levels of arsenic in drinking water and food materials continue to pose a global health challenge. Over 127 million people alone in Bangladesh (BD) and West Bengal (WB) state of India are exposed to elevated levels of arsenic in drinking water. Despite decades of research and outreach, arsenic awareness in communities continue to be low. Specifically, very few studies reported arsenic awareness among low-income farming communities. A comprehensive approach to assess arsenic awareness is a key step in identifying research and development priorities so that appropriate stakeholder engagement may be designed to tackle arsenic menace. In this study, we developed a comprehensive arsenic awareness index (CAAI) and identified key awareness drivers (KADs) of arsenic to help evaluate farmers' preferences in dealing with arsenic in the environment. The CAAI and KADs were developed using a questionnaire survey in conjunction with ten machine learning (ML) models coupled with a hybrid feature selection approach. Two questionnaire surveys comprising of 73 questions covering health, water and community, and food were conducted in arsenic-affected areas of WB and BD. Comparison of CAAIs showed that the BD farmers were generally more arsenic-aware (CAAI = 7.7) than WB farmers (CAAI = 6.8). Interestingly, the reverse was true for the awareness linked to arsenic in the food chain. Application of hybrid feature selection identified 15 KADs, which included factors related to stakeholder interventions and cropping practices instead of commonly perceived factors such as age, gender and income. Among ML algorithms, classification and regression trees and single C5.0 tree could estimate CAAIs with an average accuracy of 84%. Both communities agreed on policy changes on water testing and clean water supply. The CAAI and KADs combination revealed a contrasting arsenic awareness between the two farming communities, albeit their cultural similarities. Specifically, our study shows the need for increasing awareness of risks through the food chain in BD, whereas awareness campaigns should be strengthened to raise overall awareness in WB possibly through media channels as deemed effective in BD.

Abstract
Fungal infection of the ear canal is called Otomycosis. It is more common in hot and humid condition. There are many modalities of treatment or therapeutic agent for treatment of otomycosis. Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream is a topical antifungal agent described to be effective in the treatment of otomycosis. This study was performed to compare the efficacy of topical application clotrimazole 1% solution and Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream in the treatment of otomycosis. A controlled, randomized and open clinical trial was carried out in ENT department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh from January 2020 to July 2020. Patients diagnosed with fungal otitis externa who were treated with topical antifungals were included in this study. They were randomized into two treatment groups: i) Clotrimazole 1% solution, 2) Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream. Patients were microscopically evaluated at two weeks of treatment to determine resolution of disease. Recurrence and complications were recorded. Demographic and clinical variables were collected and analyzed, follow up and final outcomes (absence of infection) were compared between two groups. One hundred & two (102) patients were included, 51 in the clotrimazole 1% solution group and 51 in the Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream group. Predominant symptoms are pain, pruritus, aural fullness and hearing loss. Aspergillus organism was isolated most frequently (63.73%). Treatment with clotrimazole 1% solution groups resulted in 88.23% resolution vs. 80.39% resolution with Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream at 2 weeks of treatment. Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream group demonstrated higher treatment failure 11.76 and 19.60 respectively. Clotrimazole 1% solution is more effective than Econazole Nitrate 1% + Triamcinolone Acetonide 0.1% cream for uncomplicated otomycosis. More study is needed to corroborate our results.

Abstract
Multi-drug resistant Typhoid fever (resistant to previously used chloramphenicol, ampicillin, amoxicillin, and trimethoprim-sulfamethoxazole) has been commonly described in the South East Asia region and a recent report suggests that the salmonella typhi have reduced response to fluoroquinolones (nalidixic acid-resistant). The optimum treatment protocol for this type of serovar has not been established. This study compared different antimicrobial regimens for the treatment of uncomplicated typhoid fever which was conducted in the medicine ward of Dhaka Medical College Hospital (DMCH) and outdoor setting in private practice in Dhaka metropolitan city, Mymensingh and Sylhet town from January 2017 to December 2017. Bangladeshi adults with uncomplicated typhoid fever were included in this an open-label randomized controlled trial. Ciprofloxacin (20mg/kg of body weight/day for 14 days), azithromycin (20mg/kg/day for 14 days), and Cefixime (16mg/kg/day for 14 days) were compared. Of the 81 enrolled patients, 62 were eligible for analysis (61 S. enterica serovar Typhi, 1 Salmonella enterica serovar paratyphi A). Of the S enterica serovar Typhi isolates, 88.7% (55/62) were MDR and 93.5% (58/62) were nalidixic acid resistant (NAR). The clinical cure rate was 62% (13/21) with ciprofloxacin, 71% (15/21) with Cefixime, and 85% (17/20) with azithromycin (p=0.053). The mean (95% confidence interval [CI]) fever clearance time for patients treated with azithromycin (5.8 days [5.1 to 6.5 days]) was shorter than that for patients treated with cefixime (7.1 days [6.2 to 8.1 days]) and ciprofloxacin (8.2 days [7.2 to 9.2 days]) (p<0.001). All three antibiotics were well tolerated. A 7-day course of azithromycin can be successfully used in uncomplicated typhoid fever due to isolates of MDR S enterica serovar Typhi.

Abstract
The most devastating pandemic of this era coronavirus disease-2019 (COVID-19) is caused by a novel virus named severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Although it is primarily a respiratory pathogen, it can also result in several extra-pulmonary manifestations includes gastrointestinal symptoms, hepatocellular injury. Angiotensin-converting enzyme-2 (ACE-2) receptor and transmembrane serine protease 2 (TMPRSS2), the entry receptor for the causative coronavirus SARS-CoV-2 is co-express in the gastrointestinal tract, hepatocyte, and cholangiocytes similar to the respiratory mucosa. The presence of these receptors facilitates the entry into the tissue and causes direct viral tissue damage, which is a proposed mechanism of injury. Diarrhoea, nausea, vomiting, abdominal discomfort are common gastrointestinal manifestations, whereas derangement of liver function tests is the most hepatic manifestation in COVID-19. In this article, we reviewed on SARS-CoV-2 disease COVID-19 regarding gastrointestinal, hepatic, and pancreatic manifestation, the mechanisms by which the virus may inflict damage, and their management perspective.

Abstract
In this research work, we propose macronutrients incorporated slow-release based nano-fertilizer using nanozeolite as a carrier. A simple chemical approach was used to synthesis the proposed nanozeolite composite fertilizer (NZCF). To gain an insight into the properties, morphology and structure of the synthesized NZCF, it was further characterized by different techniques such as powder XRD, FT-IR, SEM, and TG/DTA. A considerable enhancement of the quality and the water retention capacity of the soil was observed as a result of applying the proposed NZCF when compared with a commercial fertilizer. Furthermore, the swelling ratio and the equilibrium water content of NZCF were compared to the commercial fertilizer and their effect on plant growth was observed. Slow-release studies were carried out for both NZCF and the commercial fertilizer. The results of these studies reveled that NZCF possessed a long-term release pattern of the macronutrients and that showed a great potential for promoting plant growth. Hence, the prepared nanocomposite fertilizer can be safely used as an environment-friendly source of nutrients to enhance plant growth.

Abstract
Oral submucous fibrosis (OSF) is a chronic complex potentially pre-malignant condition caused by chewing areca nut and other irritants. It is an insidious process characterized by Juxta-epithelial deposition of fibrous tissue in the oral cavity and pharynx. OSF is very common in Southeast Asia and also now a days increase in Europe and North America. The aim of this study to compare the effectiveness of intralesional injection of triamcinolone and hyalurunidase versus intralesional injection of triamcinolone plus injection hyalurunidase with oral colchicine. The study included 60 patients of clinically diagnosed case of oral submucous fibrosis. Patients were divided into two Groups A and B. Group A patients received combination intralesionsl injection of triamcinolone acetonide 10mg/ml in 1ml with injection hyalurunidase 1500IU in 2ml with injection 2% lidocaine 7ml. 15 days interval in 3 months and Group B received intralesional injection of triamcinolone acetonide 10mg/ml in 1ml with injection hyalurunidase 1500IU in 2ml with injection 2% lidocaine 7ml in each 15 days interval for 3 months with oral colchicine 0.5mg twice daily for 3 months. Diagnosis based on burning sensation of mouth, blanching of mucosa, ulceration in oral cavity and also reduced mouth opening. Follow up assessment was done at intervals 1st follow up on 21st days after starting of treatment then 2nd follow up after 3 months and last 3rd follow up after 6 months. Before starting of treatment all patients were properly explained about the study and took their written consent. Much more improvement occurred in Group B patients, reducing in burning sensation and also increases in opening of mouth. In both groups blanching mucosae were improved. Treatment regimen of Group B is more effective in increasing mouth opening and improves burning sensation of oral cavity. No side effects were seen in both groups' patients.

Abstract
Fertilization with organic matter (farm yard manure and/or rice straw) is thought to enhance arsenic (As) mobilization into soil porewaters, with subsequent As assimilation by rice roots leading to enhanced translocation to the grain. Here, interlinked experiments (field manuring and soil batch culture) were conducted to find the effect of organic matter at a field application rate practiced in Bangladesh (5 t/ha) on As mobilization in soil for paddies impacted by As contaminated groundwater irrigation, a widespread phenomenon in Bangladesh where the experiments were conducted. Total As concentration in a paddy soil (Sonargaon) ranged from 21.9 to 8.1 mg/kg down the soil profile and strongly correlated with TOC content. Arsenic, Fe, Mn, and DOC release into soil solution, and As speciation, are intimately linked to OM amendment, soil depth and temporal variation. Organic matter amendments lead to increased mobilization of As into both soil porewaters and standing surface waters. The As speciation in the porewater was dominated by inorganic As (Asi) (arsenite and arsenate), with traces amounts of methylated species (DMAV and MMAV) only being found with OM amendment. It was noted in field trials that OM fertilization greatly enhanced As mobility to surface waters, which may have major implications for the fate of As in paddy agronomic ecosystems.

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
Diabetic retinopathy (DR) is the most frequent microvascular complication of diabetes mellitus (DM). DR remains a leading cause of blindness, currently accounting for 4.8% of the world's 37 million blindness cases. DR is one of the critical preventable causes of blindness. In Bangladesh, the number of studies reporting the prevalence and risk factors of DR in type 2 DM (T2DM) is limited. We conducted this cross-sectional study in a tertiary hospital in Bangladesh from March 2017 to August 2019 among 200 patients with T2DM for the presence and severity of DR by using color fundus photography in a dilated pupil. The diagnosis and grading of DR were made using the Early Treatment of Diabetic Retinopathy Study (ETDRS) Chart. Out of 200 subjects with T2DM, 35.5% had DR; the frequencies of NPDR and PDR were 19.0% and 16.5%, respectively. The mean age, diabetes duration, FPG, HbA1c, TG, TC, LDL-C, and serum creatinine were statistically higher, and eGFR was lower in the study subjects with DR than those without DR; BMI and HDL-C were indifferent in the two groups. The frequencies of males, subjects having monthly income of 10,000 Bangladeshi Taka (BDT) or more, smokers, hypertensives, and subjects having uncontrolled diabetes (HbA1c ≥7%), were higher in the DR group than the no DR group. Higher age (≥50 years), higher monthly income (≥10,000 BDT), urban residence, smoking, uncontrolled diabetes, and high LDL-C (≥100mg/dL) were found to be independent risk factors of DR in the study subjects. A large-scale nationwide study is needed to find out the actual prevalence of DR in Bangladesh.

Abstract
This prospective study was conducted at Department of ENT, Mymensingh Medical College Hospital, a tertiary care center in Bangladesh January 2017 to December 2018 to report hearing results and post operative complications of cartilage interposition ossiculoplasty in one-stage intact canal wall (ICW) tympanoplasty for cholesteatoma where ossicular chain is eroded or has to be removed either partially or totally. Total 42 patients underwent Intact canal wall (ICW) tympanoplasty for cholesteatoma with at least intact stapes footplate and in conjunction, cartilage ossiculoplasty was done during the same procedure. Patients were followed up regularly at 1 week, 1 month, 3 month, 6 month and at 1 year as usual follow up protocol to note complications and hearing status in 1 year follow up. In intact stapes suprastructure group, in the preoperative period, the mean air conduction thresholds (AC), bone conduction threshold (BC) and air-bone gap (ABG) were 48.3db, 9.5db and 38.8db respectively. Postoperatively, with a mean follow-up of 12 months, AC, BC and ABG were 27.6db, 9.7db and 17.9db respectively. In missing stapes supra structuregroup, in the preoperative period, the mean air conduction thresholds (AC), Bone conduction threshold (BC) and air-bone gap (ABG) were 57.4db 13.5db and 43.9db respectively. Postoperatively, with a mean follow-up of 12 months, AC, BC and ABG, were 33.9db, 14.2db and 19.7db respectively. For management of cholesteatoma cases, cartilage ossiculoplasty can be done effectively in conjunction with of intact canal wall tympanoplasty in a single setting. Complications are a few and easily manageable. Hearing results are at least as good as with other prosthesis and helps in avoiding subsequent surgery, discomfort and cost to the patients.

Abstract
Type 2 diabetes considered as a compound of metabolic syndrome. It can cause both micro and macrovascular complications. Diabetes is a strong risk factor in the development of atherosclerosis and likewise carotid artery disease. Carotid artery stenosis may cause stroke. Doppler ultrasound is the most common imaging technique for the diagnosis of carotid disease. Objective of the study was to assess the percentage of atherosclerotic carotid disease in asymptomatic Type 2 diabetics (T2D) by Doppler sonography and to find out the association of different risk factors of diabetic patient with atherosclerosis. A cross sectional study was done. A total of 43 type 2 diabetic patients (27 male, 16 female) referred from the out patient department and admitted patients in Mymensingh Medical College Hospital (MMCH) during January 2017 to December 2017 for the purpose of evaluation of intima media thickness (IMT) and carotid artery stenosis by Duplex color Doppler ultrasonography examination were enrolled in this study. Patients with previous history of recent stroke or transient ischemic attack (<6 weeks), history of carotid surgery or cervical radiotherapy were excluded. Carotid artery disease was found 65.1% in asymptomatic type 2 diabetics. Among them increased IMT in 48.8% and carotid stenosis was present in 37.2% and >50% stenosis (Peak systolic velocity >125cm/sec) was present in 9.3%. Age >50% years, smoking, duration of DM >10 years, hypertension, history of ischaemic heart disease and history of diabetic retinopathy were found to be associated with carotid atherosclerosis as well as carotid stenosis. High percentage of carotid artery disease (65.1%) was found in asymptomatic type 2 diabetes mellitus. This result suggests the need for carotid Doppler evaluation of all Type 2 diabetics as a first measure of stroke prevention, with the hope that timely intervention might avert stroke and its accompanying disability.

Abstract
Breast cancer among women is gradually increasing in Bangladesh day by day. A number of breast cancer related etiological factors identified as age, reproductive factors, menarche, menopausal status, life style, hormone replacement therapy, genetics and alcohol intake. Obesity is an important factor for developing breast cancer in different countries. Obesity is one of the modifiable factors. The aim of the study was to find out the factors which might be associated with obesity among female breast cancer patients in Bangladesh. It was a case-control study conducted at the Department of Medical Oncology, National Institute of Cancer Research & Hospital (NICRH), Dhaka, Bangladesh from August 2014 to July 2015. Ninety one case and equal numbers of age matched controls were included in the study. The mean age of the case was 42.99 (±9.24) years and that of the control was 44.11±8.97 years. Majority of patients i.e. 59.3% (n=54) in case group was in pre-menopausal state where as 52.7% (n=48) of respondents in control group were in menopausal state. Increased waist to hip ratio (>0.85) was associated with increased risk of breast cancer (OR: 8.1). This was also true for increased BMI of ≥25kg/m² (OR: 4.57), increased waist circumference (OR: 3.52) and ever OCP use (OR: 2.11). However, para >3, education and moderate to heavy work were found to be protective against breast cancer (OR: <1). In clinical setting waist-to-hip ratio, body mass index (BMI) and waist circumference (WC) can be used effectively to identify women with an increased risk of breast cancer.

Abstract
Diabetic nephropathy (DN) is the leading cause of end-stage renal disease worldwide. Due to severe morbidity and mortality of DN and limited effective therapies, research has mainly focused on prevention of this debilitating illness by modification of risk factors. Aims of this study were to find out the prevalence of diabetic nephropathy, its factors and to correlate the functional status of the kidney. This cross-sectional study was conducted in the Department of Endocrinology, Mymensingh Medical College Hospital, Mymensingh, Bangladesh from 1st January 2013 to 30th June 2013. A total 105 patients having clinical diagnosis of Diabetes mellitus were enrolled in this study. Data were collected by interview of the patients, clinical examination and laboratory investigation. Data was analyzed using the Chi-square test for Categorical variables and unpaired Student's 't' test for differences in means for continuous variables. P value <0.05 was considered significant. With DN (30.5%) patients 21.1% had micro-albuminuria and 9.5% had macro-albuminuria. The mean age for the DN patient was 47.9±14.7 years and male female ratio was 1:1. BMI was found significantly low in patients with DN (p<0.05). Prolonged duration of diabetes (>5 years) and uncontrolled diabetes were found as significant risk factors associated with DN. Other risk factors were hypertension, family history of hypertension, family history of diabetes mellitus and irregular treatment of diabetes mellitus. Mean serum creatinine, mean estimated glomerular filtration rate (GFR) and mean blood sugar level was 1.3±0.6mg/dl, 69.4±26.7ml and 15.6±7.1mmol/L respectively in DN patients. Relation was significant for higher serum creatinine and lower eGFR values (p<0.05). Prevalence of diabetic nephropathy was 30.5%. Long standing diabetes (>5 years) and uncontrolled diabetes were the important risk factors for the development of diabetic nephropathy. Diabetic nephropathy is associated with higher serum creatinine and lower eGFR values.

Abstract
Rhinosporiodiosis is a chronic granulomatous infection of the mucus membranes caused by Rhino sporidium seeberi that manifest as vascular friable polyps and arise in the nasal mucosa. The mode of infection is probably trans-epithelial penetration. Rhinosporiodiosis is endemic in India, Pakistan and Srilanka. It occurs sporadically in the United States of America. The aim of this study was to compare betweenthe outcomes of endoscopic sinus surgery andsurgical excision in rhinosporiodiosis. The cross sectional comparative study was conducted among 40 patients with rhinosporiodiosis from January 2018 to April 2019 in the department of Otolaryngology and Head-neck surgery of Mymensingh Medical College Hospital, Bangladesh. All the patients were following up to 6 month after surgery. Most of them are male 24(60.0%) and female are 16(40.0%). Age of the patients in this study was (Mean±SD) 34.8±13.5 years. More than half of the patients had rhinosporiodiosis in the inferior turbinate (25, 62.5%) followed by 8(20.0%) in nasal septum and 7(17.5%) in the nasal floor. Endoscopic Sinus Surgery was done purposively among 20 patients and surgical excision was done purposively among another 20 patients. At the time of operation no complication occurs in case of endoscopic sinus surgery but in case of surgical excision small of amount bleeding was present. All the patients were followed up to 6 month after surgery. No recurrence was found in patients with endoscopic sinus surgery but 7(35.0%) patients who underwent surgical excision had recurrence of rhinosporiodiosis at follow up after six months of surgery. Chi-square test showed that the incidence of recurrence after 6 months of surgery was significantly lower in endoscopic sinus surgery (p=0.004). The study results concluded that endoscopic sinus surgery is better option for rhinosporiodiosis.

Abstract
Cutting and ligation of facial artery is the conventional practice for excision of submandibular gland. Facial artery is the main arterial supply to the lower face. Its preservation results in preservation of large proportion of vascularity to the lower face, preserves vascularity of platysma myocutaneous flap, allows repair of lower lip using Bernard's technique; facial artery is one of the most important recipient artery for microvascular free flap in modern reconstructive surgery in head and neck oncology. This prospective study was carried out in Department of Otolaryngology, Bangabandhu Sheikh Mujib Medical University Hospital (BSMMU), Dhaka, Bangladesh from October 2005 to October 2012 on 31 cases. Chronic submandibular sialoadenitis, benign submandibular gland tumours and cases of neck dissection where level I cervical lymph nodes were not involved by metastasis were included in this study. The facial artery was identified proximal to the gland and was dissected free from the gland by ligating or cauterizing its glandular branches to mobilize the gland. Appropriate anatomical aspects were noted and the time required for separation of the artery from the gland was recorded. Thirty-one consecutive cases were studied. The indications were chronic sialoadenitis (67.7%), pleomorphic adenoma (12.9%) and as a part of neck dissection for oncologic clearance of neck (19.4%). The mean duration of time for separation of the artery from the gland was 10.26 minutes. In two cases the facial artery could not be safely separated due to excessive adhesion from chronic inflammation. No significant complications were noted. Preservation of facial artery in submandibular gland excision is a simple procedure. So it should not be routinely sacrificed during this surgery.

Abstract
An individual of Banded Lineblue Prosotas aluta was discovered in Bangladesh on 7 September 2018 from the Kaptai National Park, a mixed evergreen protected forest in the southeastern region of the country. The discovered species was found in the hill stream named ‘Boro Chara’. The photographic documentation confirms the certainty of the species. The occupancy of P. aluta in Asia and distribution around Bangladesh in Cachar and Khasi Hills of India indicate its existence but confirmation was wanting till date. Hence, we report the first confirmed record from Bangladesh.

Abstract
Among nurses due to inadequate pain management knowledge and practice skills, children's pain is often under treated. This study aimed to examine the level of knowledge and practice on pediatric pain management among nurses in Bangladesh. This was a descriptive survey study involving total 150 clinical pediatric nurses from two Medical College Hospital and a University hospital in Bangladesh. The data collection tool consisted of demographic data form, 32-items nurses' knowledge. There were 32 true and false questions related to nurses' knowledge on pediatric pain management in Bangladesh. The response formats to each item for correct answer was 1 and incorrect answer 0. The total scores were categorized into three levels including low (0-20), moderate (21-23) and high (24 and above). The data collection tool consisted of demographic data form, 19-item practice related questionnaire on pediatric pain management. Nurses' practice on pediatric pain management contained 19 items with 5-points Likert's scale ranging from 1=Never practice to 5=constantly practice. For each item, a score of 5 was accorded for constantly and 1 for never. The score ranged from 19-95. The total scores were categorized into three levels including low (19-38), moderate (39-76) and high (77-95). The results demonstrated that most of the nurses' knowledge score on pediatric pain management was at moderate level (mean=21.50, SD=2.35). Nurses' practice on pediatric pain management was also at moderate level (mean=75.45, SD=8.24). The relationship between nurses' knowledge and practice was not significant. In addition, nurses' knowledge and practice with demographic variables; there was significant relationship between nurse's knowledge and existence of pain management protocol, nurses' practice and their current position in unit and with reading nursing journal. This study showed moderate level of knowledge and practice indicating that they need to be enhanced the knowledge and practice skills in pediatric pain management.

Abstract
The diurnal feeding patterns of dairy cows affects the 24 h robot utilisation of pasture-based automatic milking systems (AMS). A decline in robot utilisation between 2400 and 0600 h currently occurs in pasture-based AMS, as cow feeding activity is greatly reduced during this time. Here, we investigate the effect of a temporal variation in feed quality and quantity on cow feeding behaviour between 2400 and 0600 h as a potential tool to increase voluntary cow trafficking in an AMS at night. The day was allocated into four equal feeding periods (0600 to 1200, 1200 to 1800, 1800 to 2400 and 2400 to 0600 h). Lucerne hay cubes (CP = 19.1%, water soluble carbohydrate = 3.8%) and oat, ryegrass and clover hay cubes with 20% molasses (CP = 11.8%, water soluble carbohydrate = 10.7%) were offered as the 'standard' and 'preferred' (preference determined previously) feed types, respectively. The four treatments were (1) standard feed offered ad libitum (AL) throughout 24 h; (2) as per AL, with preferred feed replacing standard feed between 2400 and 0600 h (AL + P); (3) standard feed offered at a restricted rate, with quantity varying between each feeding period (20:10:30:60%, respectively) as a proportion of the (previously) measured daily ad libitum intake (VA); (4) as per VA, with preferred feed replacing standard feed between 2400 and 0600 h (VA + P). Eight non-lactating dairy cows were used in a 4 × 4 Latin square design. During each experimental period, treatment cows were fed for 7 days, including 3 days habituation and 4 days data collection. Total daily intake was approximately 8% greater (P < 0.001) for the AL and AL + P treatments (23.1 and 22.9 kg DM/cow) as compared with the VA and VA + P treatments (21.6 and 20.9 kg DM/cow). The AL + P and VA treatments had 21% and 90% greater (P < 0.001) dry matter intake (DMI) between 2400 and 0600 h, respectively, compared with the AL treatment. In contrast, the VA + P treatment had similar DMI to the VA treatment. Our experiment shows ability to increase cow feeding activity at night by varying feed type and quantity, though it is possible that a penalty to total DMI may occur using VA. Further research is required to determine if the implementation of variable feed allocation on pasture-based AMS farms is likely to improve milking robot utilisation by increasing cow feeding activity at night.

Abstract
Hypertension has its origin in childhood but goes undetected unless specially looked for detection of hypertension in children will increase the awareness and lead to preventive strategies. The objective of the study was to determine the prevalence of hypertension in school children. This cross sectional study was conducted among children aged 10 to 17 years in three secondary level schools of Dhaka city, Bangladesh. This study included 1146 participants (both boys and girls) by systematic random sampling. Blood pressure was measured and plotted in Blood pressure (BP) chart to define hypertension and structured questionnaire were used to collect socio demographic information. The prevalence of hypertension in school children was 1.8% (male was 1.68% and female was 1.99%). It was noted that there was a strong correlation between body weight and BMI of the children with hypertension. A significant portion of the respondents had family history of hypertension, diabetes and obesity. There was also a positive relation between hypertension and food habit that include low vegetables and more fast food. It was concluded that hypertension exists among secondary level school children in Dhaka, Bangladesh and it is related with obesity, increased BMI, family history and dietary habit.

Abstract
The mechanical behavior of athermal random fiber networks embedding particulate inclusions is studied in this work. Composites in which the filler size is comparable with the mean segment length of the network are considered. Inclusions are randomly distributed in the network at various volume fractions, and cases in which fibers are rigidly bonded to fillers and in which no such bonding is imposed are studied separately. In the presence of inclusions, the small strain modulus increases, while the ability of the network to strain stiffen decreases relative to the unfilled network case. The reinforcement induced by fillers is most pronounced in sparse networks of floppier filaments that deform in the bending-dominated mode in the unfilled state. As the unfilled network density or the bending stiffness of fibers increases, the effect of filling diminishes rapidly. Fillers lead to a transition from the soft, bending-dominated, to the stiffer, stretching-dominated, deformation mode of the network, a transition which is primarily responsible for the observed overall reinforcement. The confinement, i.e., the restriction on network kinematics imposed by fillers, causes this transition. These results provide a justification for the observed difference in reinforcement obtained in sparsely versus densely cross-linked networks at a given filling fraction and provide guidance for the further development of network-based materials.

Abstract
Using village-based rice processing plants in rural Bangladesh, this study considered how parboiling rice could be altered to reduce the content of the carcinogen inorganic arsenic. Parboiling is normally conducted with rough rice (i.e., where the husk is intact) that is soaked overnight at ambient temperatures, and then either steamed or boiled for ∼10 min, followed by drying. Across 13 geographically dispersed facilities it was found that a simple alteration parboiling wholegrain, instead of rough rice, decreased the inorganic arsenic content by 25% ( P = 0.002) in the final polished grain. Also, parboiling wholegrain had little impact on milling quality of the final polished rice. The wholegrain parboiling approach caused statistically significant median enrichment of calcium, by 213%; and a reduction in potassium, by 40%; with all other nutrient elements tested being unaffected. Milled parboiled rough rice had an enriched inorganic arsenic compared to nonparboiled milled rice, but parboiling of wholegrain rice did not enrich inorganic arsenic in the final milled product. Polished rice produced from the parboiling of both rough and wholegrain rice significantly reduced cadmium compared to nonparboiled polished rice, by 25%. This study also identified that trimethylarsine oxide and tretramethylarsonium are widely elevated in the husk and bran of rice and, therefore, gives new insights into the biogeochemical cycling of arsenic in paddy ecosystems.

Abstract
Sympathetic ophthalmitis (SO) is defined as bilateral granulomatous panuveitis occurring after penetrating ocular trauma or intraocular surgery. It is now rare due to micro-surgical repair of ocular injury and use of steroid. An 18 years old boy admitted into Ophthalmology department of Mymensingh Medical College Hospital, Mymensingh, Bangladesh on 2nd March 2018. He got penetrating corneal injury in R/E with sharp pointed object 01 month back. It was conservatively managed but his right eye became phthisical. After 04 weeks his left eye was affected in which VA became 3/60, features of panuveitis developed. It was managed with high dose steroid and immunomodulatory drug (Azathioprine). Ultimately his vision of left eye is fully preserved (6/6). So, after a trauma or surgery to one eye, another eye should be meticulously examined and followed up. Early diagnosis and prompt treatment of Sympathetic Ophthalmitis may prevent from blindness.

Abstract
This cross sectional study was carried out in the Department of Radiology & Imaging, Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM), Dhaka, Bangladesh from July 2010 to June 2011 with a view to evaluate the diagnostic accuracy of refractory shadowing on transabdominal pelvic sonography for leiomyomas and in differentiating them from other pelvic masses. Histopathological examination of the surgically resected masses was taken as the standard diagnostic tool. A total number of 50 patients of pelvic masses were studied. It was observed that a pattern of sharp, discrete, shadow was typical of leiomyoma, which reduces diagnostic ambiguity. The mean age of the patients was 38 years. Mean size of the masses was 4.25±3.25cm. Taking histopathological examination as the Gold standard, accuracy of refractory shadowing on transabdominal sonography in diagnosis of leiomyoma was 65.1%. Specificity and sensitivity were 90.3% and 54.2% respectively. Positive predictive value was 92.9% and negative predictive value was 45.9%. Statistical analysis revealed strong association of refractory shadowing with diagnosis of leiomyomas (p<0.01).

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.
