ALIGNING ASSESSMENT WITH OUTCOME BASED ASSESSMENT: AN EMPIRICAL STUDY ON UNDERGRADUATE COURSE ON FUNDAMENTALS OF STATISTICS

Since the Institution of Engineers, Bangladesh (IEB) has made Outcome Based Assessment (OBA) compulsory towards program accreditation it has been one of the vital interests of most engineering departments in Bangladesh. When considering the mapping of the Course outcome (CO) to Program Outcomes (PO) implementation of the OBA may not be an easy task. This paper reports the analysis procedure of the CO and PO achievement for an B.Sc. course on Fundamentals of Statistics, a subject, which is part of curriculum of Electrical & Electronics Engineering and Computer Science and Engineering at Eastern University, Bangladesh. As a sum, this paper contributes complete process and an example investigation for Outcome Based Valuation starting from course curriculum progress to its CO-PO achievement based on definite criteria.  Article visualizations

Bacterial Isolates and Antimicrobial Susceptibility in Children with Acute Diarrhea at Ibn Sina Medical College, Bangladesh

Backround: Infectious diarrhea is one of common cause of children diarrhea causing mortality and morbidity worldwide. This study was performed to identify the common bacteria and their antimicrobial susceptibility in children with diarrhea. Methods: A retrospective study was conducted from April 2014 to March 2016 at IBN SINA Medical College Hospital, Bangladesh. Stool samples were cultured on MacConkey agar and blood agar. A standard biochemical procedure was used for full identification of bacterial isolates. Antimicrobial susceptibility tests were done on Mueller-Hinton agar by using disc diffusion method. Data were entered and analyzed by using SPSS version 20 and a p-value of < 0.05 was considered statistically significant. Results: A total of 186 stool samples were tested for bacterial isolation and 55 (29.57%) cases were found to have bacterial isolates. From the total bacterial isolates, the predominant isolate was E. coli 39 (70.91%) followed by Salmonella 9 (16.36%) and Shigella Spp.7 (12.73%). As much as 84.62% E. coli were resistant to co-trimoxazole and cefuroxime while 92.31% E. coli were sensitive to amikacin and 71.79% were sensitive to cefepime and gentamicin. Salmonella were 100% sensitive to cefepime, ceftriaxone, cefixime, ceftazidime, and ciprofloxacin. Shigella were 85.71% sensitive to amikacin and cefepime. Conclusion: The results show that E. coli were the most frequently isolated pathogen in children. The majority of the bacterial isolates were resistant to multiple antibiotics. Hence, antibiotics susceptibility test is mandatory before prescribing any antibiotics

Scientific Reports, 9(1), 6237. https://doi.org/10.1038/s41598-019-42616-wSwine movement networks among farms/operations are an important source of information to understand and prevent the spread of diseases, nearly nonexistent in the United States. An understanding of the movement networks can help the policymakers in planning effective disease control measures. The objectives of this work are: (1) estimate swine movement probabilities at the county level from comprehensive anonymous inventory and sales data published by the United States Department of Agriculture - National Agriculture Statistics Service database, (2) develop a network based on those estimated probabilities, and (3) analyze that network using network science metrics. First, we use a probabilistic approach based on the maximum information entropy method to estimate the movement probabilities among different swine populations. Then, we create a swine movement network using the estimated probabilities for the counties of the central agricultural district of Iowa. The analysis of this network has found evidence of the small-world phenomenon. Our study suggests that the US swine industry may be vulnerable to infectious disease outbreaks because of the small-world structure of its movement network. Our system is easily adaptable to estimate movement networks for other sets of data, farm animal production systems, and geographic regions

Understanding the role of sexual transmission in the spread of ZIKA virus using an individual-based interconnected population model

Citation: Tanver, F., Lee, C., Mcvey, D., & Scoglio, S. (2018). Understanding the role of sexual transmission in the spread of ZIKA virus using an individual-based interconnected population model. Pre-Print, Unpublished Manuscript.Zika virus has affected the world as a long-term threat. Modeling its transmission is important in order to facilitate forecasts and control measures. We propose a novel node-based interconnected population model to simulate both vectored and sexual transmission of Zika virus. Using a sexual contact network, we incorporate heterogeneous mixing in the host population with stochastic transmission for realistic predictions. We also incorporate climatic variations in our model, which affect the mosquito vector population and consequently the arbovirus transmission. We perform extensive simulations to understand the effects of sexual transmission rate and network topology on the spreading of infections. Sexual transmission contributes to the epidemic spread and under certain conditions, can sustain it up to several months without vectors. This can potentially lead to recurrences once the mosquitoes overwinter. We also find that sexual transmission can have a stronger effect when vectored transmission is relatively weaker due to climatic conditions. Our results show that vectored and sexual transmission affect the disease dynamics differently

Corneal Confocal Microscopy Detects Small Fibre Neuropathy in Patients with Upper Gastrointestinal Cancer and Nerve Regeneration in Chemotherapy Induced Peripheral Neuropathy.

Published onlineThere are multiple neurological complications of cancer and its treatment. This study assessed the utility of the novel non-invasive ophthalmic technique of corneal confocal microscopy in identifying neuropathy in patients with upper gastrointestinal cancer before and after platinum based chemotherapy. In this study, 21 subjects with upper gastrointestinal (oesophageal or gastric) cancer and 21 healthy control subjects underwent assessment of neuropathy using the neuropathy disability score, quantitative sensory testing for vibration perception threshold, warm and cold sensation thresholds, cold and heat induced pain thresholds, nerve conduction studies and corneal confocal microscopy. Patients with gastro-oesophageal cancer had higher heat induced pain (P = 0.04) and warm sensation (P = 0.03) thresholds with a significantly reduced sural sensory (P<0.01) and peroneal motor (P<0.01) nerve conduction velocity, corneal nerve fibre density (CNFD), nerve branch density (CNBD) and nerve fibre length (CNFL) (P<0.0001). Furthermore, CNFD correlated significantly with the time from presentation with symptoms to commencing chemotherapy (r = -0.54, P = 0.02), and CNFL (r = -0.8, P<0.0001) and CNBD (r = 0.63, P = 0.003) were related to the severity of lymph node involvement. After the 3rd cycle of chemotherapy, there was no change in any measure of neuropathy, except for a significant increase in CNFL (P = 0.003). Corneal confocal microscopy detects a small fibre neuropathy in this cohort of patients with upper gastrointestinal cancer, which was related to disease severity. Furthermore, the increase in CNFL after the chemotherapy may indicate nerve regeneration

Status and Social Evaluation towards Beggars in Bangladesh: Context of Sylhet City

Beggary is an important social phenomenon and one of the major social problems for all over the developed, underdeveloped and developing countries in the world. Bangladesh is a developing country in the South Asia, affected by the beggary problem due to the poor socio-economic conditions, poverty, lack of working opportunities etc. Sylhet city is an important city in Bangladesh as natural resource and foreign remittance are important part in the national economy, but is not free from beggary problems. Among the beggar’s family more than 60% are involved in begging  due to low income (Taka 1000-3000/$12.8-38.5- 14.3%) and inadequate property (62.86%) as such as- land, deposit money, investment and other exchangeable assets etc. to make-up the imbalance of monthly income and expenditure. This is why their family are incapable to maintain all the essential needs which push them to involve in beggary and various starve (74.29%) in their family life

Complications of Ilizarov method treatment for infected nonunion femoral shaft fracture

Background: Infected non-union of the femur is complicated by the involvement of soft tissue and bone, long-term resistant multi-bacterial infection, limb length discrepancy, deformities, joint stiffness, and multiple draining sinuses, and poses a challenge for orthopedic surgeons. This study aimed to analyze the complications of Ilizarov method treatment for infected non-union femoral shaft fracture. Methods: This prospective observational study was conducted at the national institute of traumatology and orthopedic rehabilitation (NITOR), Dhaka, Bangladesh, from May 2018 to August 2020. A total of 20 patients were selected as study subjects by purposive sampling technique. All data were collected using a pre-formed questionnaire. Data were processed and analyzed using computer software program SPSS version 22.0. Result: The mean bone gap created during the operation was 2.7±1.7 cm of them, in 12 (60%) patients, it was 0 to 2 cm, and in 8 (40%) patients it was more than 2 cm. The mean time needed for radiological union was 7.85±2.1 months ranging from 5 months to 11 months. In 10 (50%) patients, union was achieved within 4 to 7 months, and in 10 (50%) patients it was 8 to 11 months. Regarding limb length discrepancy, in 5 (25%) cases there was no limb length discrepancy (LLD). Twelve patients had 1 cm to 2.4 cm LLD and 3 (15%) patients had ≥2.5 cm LLD. The mean LLD was 1.2±0.9 cm. Regarding complications, in 10 (50%) cases, there was no complication and 10 (50%) patients had complications. The complications were pin tract infection in 7 (35%) patients and wire loosening in 3 (15%) patients. Conclusions: The study concludes that while the Ilizarov ring fixator proves to be a dependable and successful method for stabilizing, correcting length discrepancies, and eliminating infections, it is not without its share of complications. The findings of this research indicate a 50% complication rate among the patients undergoing this treatment
