Enhancing viral pneumonia diagnosis accuracy using transfer learning and ensemble technique from chest x-ray images

Pneumonia is an acute pulmonary infection that can be caused by bacteria, viruses, or fungi. It infects the lungs, causing inflammation of the air sacs and pleural effusion: a condition in which the lung is filled with fluid. The diagnosis of pneumonia is tasking as it requires a review of Chest X-ray (CXR) by specialists, laboratory tests, vital signs, and clinical history. Utilizing CXR is an important pneumonia diagnostic method for the evaluation of the airways, pulmonary parenchyma, and vessels, chest walls among others. It can also be used to show changes in the lungs caused by pneumonia. This study aims to employ transfer learning, and ensemble approach to help in the detection of viral pneumonia in chest radiographs. The transfer learning model used was Inception network, ResNet-50, and InceptionResNetv2. With the help of our research, we were able to show how well the ensemble technique, which uses InceptionResNetv2 and the utilization of the Non-local Means Denoising algorithm, works. By utilizing these techniques, we have significantly increased the accuracy of pneumonia classification, opening the door for better diagnostic abilities and patient care. For objective labeling, we obtained a selection of patient chest X-ray images. In this work, the model was assessed using state-of-the-art metrics such as accuracy, sensitivity, and specificity. From the statistical analysis and scikit learn python analysis, the accuracy of the ResNet-50 model was 84%, the accuracy of the inception model was 91% and lastly, the accuracy of the InceptionResNetv2 model was 96%.

Cardiovascular, respiratory and all-cause (natural) health endpoint estimation using a spatial approach in malaysia

In 2016, the World Health Organization (WHO) estimated that approximately 4.2 million premature deaths world wide were attributable to exposure to particulate matter 2.5 μm (PM2.5). This study assessed the environmental burden of disease attributable to PM2.5 at the national level in Malaysia. We estimated the population-weighted exposure level (PWEL) of PM10 concentrations in Malaysia for 2000, 2008, and 2013 using aerosol optical density (AOD) data from publicly available remote sensing satellite data (MODIS Terra). The PWEL was then converted to PM2.5 using Malaysia's WHO ambient air conversion factor. We used AirQ+ 2.0 software to calculate all-cause (natural), ischemic heart disease (IHD), stroke, chronic obstructive pulmonary disease (COPD), lung cancer (LC), and acute lower respiratory infection (ALRI) excess deaths from the National Burden of Disease data for 2000, 2008 and 2013. The averagePWELs for annual PM2.5 for 2000, 2008, and 2013 were 22 μg m-3, 18 μg m-3 and 24 μg m-3, respectively. Using the WHO 2005 Air Quality Guideline cut-off point of PM2.5 of 10 μg m-3, the estimated excess deaths for 2000, 2008, and 2013 from all-cause (natural) mortality were between 5893 and 9781 (95 % CI: 3347–12,791), COPD was between 164 and 957 (95 % CI: 95–1411), lung cancer was between 109 and 307 (95 % CI: 63–437), IHD was between 3 and 163 deaths, according to age groups (95 % CI: 2–394) and stroke was between 6 and 155 deaths, ac-cording to age groups (95 % CI: 3–261). An increase in estimated health endpoints was associated with increased estimated PWEL PM2.5 for 2013 compared to 2000 and 2008. Adhering the ambient PM2.5 level to the Malaysian AirQuality Standard IT-2 would reduce the national health endpoints mortality

Antibiotic stewardship in a vietnamese public security hospital: addressing antimicrobial resistance challenges through the aware framework

Antimicrobial resistance poses a critical threat to global health, exacerbated by inappropriate antibiotic usage. This study evaluates antibiotic consumption at Hospital 199, a public security hospital in Vietnam, using the defined daily dose per 100 bed-days and the World Health Organization AWaRe classification framework. Data were collected retrospectively from inpatient departments over 2022, analyzing prescribing trends to assess stewardship effectiveness and identify areas for improvement. The findings reveal a total antibiotic usage rate of 60.8 defined daily dose per 100 bed-days, predominantly driven by watch antibiotics (63.8%), followed by access antibiotics (36.2%), and minimal use of reserve antibiotics (0.0003%). Critical care departments, such as anesthesiology and intensive care, reported the highest consumption (190.54 DDD/100 bed-days), which may reflect the complexity of care provided and potential empirical prescribing practices, or an elevated infectious burden. β-lactam antibiotics accounted for 59.4% of total use, with third-generation cephalosporins representing the largest subgroup at 40.2% of defined daily doses. While adherence to stewardship principles was evident in the limited use of reserve antibiotics, the reliance on broad-spectrum agents highlighted systemic challenges, including empirical prescribing practices and limited diagnostic capacity. This study highlights the need for targeted interventions to promote access to antibiotics, reduce over-reliance on watch agents, and enhance diagnostic support. By aligning local practices with World Health Organization guidelines, Hospital 199 demonstrates its potential to combat antimicrobial resistance effectively. These findings offer insights for similar low- and middle-income settings, contributing to global efforts to mitigate resistance and optimize antibiotic stewardship.

Equity and equality in higher education-india calling…

Abstract Higher education in India is always a socio-political way and a powerful engine of social mobility. It adds to the benefits to society as more people earning Higher Education credentials. It is proven that college graduates earn more. They are less likely to be unemployed. They are more likely to vote, more likely to volunteer, and more likely to maintain good health. India as a Globalised and developing nation has been little systematically progressing on the educational front since its independence. The government is making progress in reaching out to all the classes of its society. The improvement in the country’s economic front has resulted in the upscaling of communication technology. The advent of the internet, have vastly leveraged the promotion of education across all verticals. But at the same time, the idea of Equity and Equality needs to be redefined in the present context of the newly established notion of ‘Inclusivity’. This paper deliberates on the various ideas and approaches of Higher Education in India on ‘Inclusivity’ in general and Equity and Equality in particular.

Strategic marketing - blog entry

Marketing refers to the actions that elevate customer value by motivating them to purchase the organisation's products or services (Kusumadewi, 2019). An organisation with strong capabilities must exhibit strong marketing capacities to effectively introduce its offerings to new markets (Lee and Falahat, 2019). Marketing strategies are part of an organisation's corporate strategy, which refers to the set of choices an organisation makes to develop and capture value across its business over time. As corporate strategy essentially drives financial performance (Sull et al., 2018), effective marketing strategies must be selected to ensure the organisation's attainment of objectives and long-term success.

Design and analysis of parallel flow heat exchanger with baffles

Shell and tube heat exchanger is the most common type of heat exchanger, widely used in oil refinery and other large chemical process. The energy present in the exit stream of many energy conversion devices such as I. C engines, Gas turbines etc. goes as waste, if not utilized properly. For example, the heat energy stored in the engine coolant can be utilized in a better way by recovering the heat for heating purposes inside the cabin. It is comparatively economical than the existing heating arrangements, which employ conventional heating coils. So, the present work has been carried out with a view to predicting the performance of a shell and tube heat exchanger in the field of waste heat recovery application. The objective of this project is to design a shell and tube heat exchanger and study the flow and temperature field inside the shell and tubes using ANSYS Fluent R14.5. An attempt has been made to calculate the performance of the above heat exchanger with and without baffles for parallel flow configurations, and the results so obtained have been compared.

The interplay of emt and stemness driving malignant transformation of oral submucous fibrosis

Background: Oral submucous fibrosis (OSF) is a persistent oral mucosal condition that carries an elevated risk of undergoing malignant transformation. Our objective was to elucidate the involvement of epithelial-tomesenchymal transition (EMT) in OSF and its progression to malignancy by studying a panel of EMT markers, thereby understanding the molecular mechanisms. Methods: An immunohistochemical analysis was done to detect the presence of E-cadherin, N-cadherin, pancytokeratin (PanCK), vimentin, α-SMA (alpha-smooth muscle actin), and CD44 in a total of 100 tissue samples. These samples comprised 40 cases of OSF, 20 cases of oral squamous cell carcinoma associated with OSF (OSFSCC), and 40 cases of oral squamous cell carcinoma (OSCC). A whole transcriptomic analysis was performed on a group of seven matched samples encompassing NOM, OSF, OSFSCC, and OSCC. Results: We observed significantly decreased expression of E-cadherin and PanCK, while N-cadherin, vimentin, α-SMA, and CD44 showed significantly higher expression in OSFSCC and OSCC as compared to OSF, both at protein and RNA levels. CD44 expression was noticeably higher in OSFSCC (p < 0.001) than in OSCC. Conclusion: Downregulation of epithelial markers with concomitant upregulation of mesenchymal and stem cell markers suggests the potential role of EMT and stemness in accelerating the pathogenesis and malignant transformation of OSF. The high levels of CD44 expression seen in OSFSCC indicate a high propensity for aggressiveness and acquisition of stem-like characteristics by the cells undergoing EMT.

Modified mini-incision surgery for carpal tunnel syndrome: technique and clinical outcome

Carpal tunnel syndrome (CTS) is caused by the shortening of the median nerves in the wrist, resulting in hand pain and paralysis necessitating surgical operation for relief. Conventional open carpal tunnel release (CTR) procedures, involving long incisions, often lead to complications, delaying patients' recovery for weeks or months. Therefore, mini-incision surgery has emerged as a preferred option, offering reduced pain, smaller wounds, and improved appearance. This study aimed to compare the outcomes of modified mini-incision surgery for CTS before and after the operation. It was a retrospective study involving 80 patients, with data collected from medical records pre-and post-operation, specifically at the 2 nd week, 3 rd month, 6 th month, 12 th month, and 24 th month intervals. Variables included operation time, incision length, pinch strength, gripping strength, two-point discrimination (2-PD), visual analogue scale (VAS), Levine score, quick disabilities of the arm, shoulder and hand (Quick-DASH), wound pain, and pillar pain. Data were analyzed using descriptive statistics and logistic regression, with a significant level of 0.05. The mean incision length was 11.54 mm. At the 2-week post-operative mark, the pinch strength was 5.43, gripping strength was 14.96, 2-PD was 5.84, the VAS score was 2.86, the Levine symptom was 3.84, and the DASH score was 69.43. There was a relationship (p-value<0.05) between preoperative and postoperative measures for pinch strength, gripping strength, 2-PD, and Levine symptom condition. The study on 80 patients who underwent modified mini-incision surgery for CTS at Naresuan University Hospital in Phitsanulok, Thailand, found that these parameters showed significant improvement postoperatively. Patients demonstrated good recovery and condition 2 weeks after the mini-incision surgery for CTS.

An empirical analysis of household consumption in rural maharashtra during march 2020

Current research investigates the nuanced impact of the COVID-19 pandemic on consumption patterns in rural Maharashtra, India. Our research has two main goals. First, we want to understand how factors like age, gender, job, education, and family size have affected how people in rural Maharashtra spent money during the pandemic. Second, we want to find out which of these factors had the biggest impact on spending in different parts of the state. Since rural areas have their own unique economic situations, we know it's important to look at how the pandemic affected these communities specifically. We're using math and tables to analyze the information and provide a detailed look at how the pandemic immediately changed spending habits and what it might mean for the future in rural households. This research is not only timely but also essential for informing policy decisions aimed at supporting rural communities in the aftermath of the pandemic. By unraveling the intricate dynamics of consumption in rural Maharashtra, we contribute to a deeper understanding of the economic challenges faced by these communities and provide insights that can guide targeted interventions to foster resilience and recovery.

Comparing machine learning classification models on a loan approval prediction dataset

In the last decade, we have observed the usage of artificial intelligence algorithms and machine learning models in industry, education, healthcare, entertainment, and several other areas. In this paper, we focus on using machine learning algorithms in the loan approval process of financial institutions. First, we briefly review some prior research papers that dealt with loan approval predictions using machine learning models. Next, we analyze the loan approval prediction dataset we downloaded from Kaggle, which was used in this paper to compare several machine learning classification models. During this analysis, we observed that credit scores and loan terms are the attributes that probably most affect the result. Next, we divided the dataset into a training set (80%) and a test set (20%). We trained 27 various machine learning models in MATLAB. Three models were optimized with Bayesian optimization to find the best hyperparameters with minimum error. We used 5-fold cross-validation for the validations to prevent overfitting during the training. In the following step, we used the test set on trained models to measure the models’ accuracy on unseen data. The result showed that the best accuracy both on validation and test data, more than 98%, was reached with neural networks and ensemble classification models.
