Examining HIV and Tuberculosis Using a Decision Support Systems Computer Simulation Model: The Case of the Russian Federation

The aim of this paper is to describe the development and use of a computer simulation model that can be used as a Decision Support System (DSS) to tackle the critical public health issues of the chronic diseases, HIV and HIV related Tuberculosis in the Russian Federation. The model was developed to enable health officials and decision makers to determine the impact of policies to control the chronic diseases spread in an area of Russia. This area, like many others in Russia and elsewhere, have recently witnessed an explosion of HIV infections and a worrying spread of the Multi Drug Resistant form of Tuberculosis (MDRTB). The conclusions drawn is that a high population coverage with Highly Active Anti Retroviral Treatment (HAART) (75% or higher), allied with high MDRTB cure rates, reduces cumulative deaths by 60%, with limited impact below this level. The contributions that this research offers are the development of a simulation model that can be applied as a DSS by public health officials and managers in order to inform policy making. By doing so, ways of best controlling the spread of HIV and MDRTB and reduce the mortality rate from these serious public health threats is provided

Assessment of glycemic status and BMI of resident and non - resident female students of Jessore University of science and technology, Bangladesh

Background: Glycemic status means blood glucose level in an individual is measure by using the term hyperglycemia and hypoglycemia. Hyperglycemia is a condition in which an excessive amount of glucose circulates in the blood plasma whereas hypoglycemia is below normal level of glucose in blood.  Abnormal Glycemic status develops various short as well as long term health complications. Constant monitoring of health status of an individual’s is important in maintaining good glycemic status in preventing development of hyperglycemia and hypoglycemia related complication.Methods: Female students ages 20 – 23 of hall resident and non resident of Jessore University of Science and Technology were randomly selected. Fasting blood glucose data and Body Mass Index (BMI) were collected on the basis of family status, income and eating pattern, family environments using standard laboratory procedures.Results: The study found that 68% resident students were in hypoglycemic whereas 60% nonresident female students were in hypoglycemic but hyperglycemic and acute hyperglycemic effect was totally absent in both group of students. Differences of BMI irregularities of both groups of students were not observed. Most of residential students (88%) were only depends on the provided food in the dining hall. Whereas nonresident students majority of them are belonged to upper middle class, living in their own house and their eating patterns were better than residential female students. Therefore, most of the nonresident female students are able to intake nutritious foods. As a result the hypoglycemic students were found less abundant in nonresidential student compared to the resident group. Therefore dieting habit is one of the most important reasons to develop irregular glycemic status.Conclusions: The need of awareness of good health care practice, intake good quality nutritious diet, avoid of abnormal dieting practice is prerequisite to maintain static glycemic status which directly linked to good health

Microbiological quality of some common dairy beverages available in Dhaka University campus of Bangladesh

Dairy beverages are nutritious and also highly susceptible to bacterial contamination posing a threat to human health. In recent years, production and consumption of dairy beverages are rapidly increasing in Bangladesh; however, the presence of bacteria including human pathogens in commonly consumed dairy beverages has not been evaluated before. Here, we focused on microbiological quality of some dairy beverages available in Dhaka University campus. We examined 25 samples from five different items locally named as Lassi, Labang, Borhani, Pistachio nut sherbet, and Strawberry milkshake. Non-selective medium PCA and different selective agar media such as MacConkey, SS, EMB, and TCBS, and Cooked Meat were used for isolation. Antibiotic resistance was assessed by disk diffusion method against Ampicillin, Colistin, Ciprofloxacin, Levofloxacin, Ceftriaxon, and Gentamycin. In PCA medium, Labang and Strawberry milkshake, respectively, showed the highest (3.6 × 107 CFU/mL) and the lowest (1.76 × 103 CFU/mL) bacterial count. In MacConkey and EMB media, the highest bacterial growths were, respectively, shown by Pistachio nut sherbet (1.22 × 104 CFU/mL) and Lassi (2.96 × 103 CFU/mL) whereas no growth was observed for Borhani. Strawberry milkshake was found with the highest bacterial prevalence such as E. coli, Klebsiella, Proteus, Pseudomonas Bacillus, Micrococcus, and Streptococcus whereas Borhani and Labang contained the lowest variety of bacteria. Isolates such as Shigella, Aeromonas, Micrococcus, Bacillus, Streptococcus, and Proteus were multi-drug resistant to Ampicillin and Colistin. Findings indicated that examined samples contained health risk factor. Findings may help relevant stakeholders to consider food safety issues of dairy beverages during processing, marketing, and consumption

An Assessment to Human Perception to the Origin of Coronavirus by the Impact of Climate Change and Preventative Management of Pandemic Coronavirus COVID-19

On 12 January 2020, the WHO confirmed that a novel coronavirus was the cause of a respiratory illness in a cluster of people in Wuhan City, China. The aims of the study to assess the human perception to the origin of Coronavirus with relation to nature and find out preventative management about coronavirus. Primary data was collected for analyzing some factors regarding the Coronavirus microorganism formed by the impact of climate change. Primary data was collected through an online questionnaire survey. An online questionnaire survey is used for human perception for taking public opinion about the origin of Coronavirus and preventative management which are conducted in Bangladesh. SPSS software is used for Linear Regression analysis and correlation with some variables. A total of three variables were considered in the model estimation of which are dependent variables Coronavirus microorganism formed by the impact of climate change and independent variables such as Coronavirus microorganism formed by the impact of environmental pollution, Coronavirus microorganism formed by the impact of global heat and Coronavirus microorganism originated by the sources of the impact of ice melting polar region. From the analysis, it is found that the Coronavirus microorganism formed by the impact of climate change that makes a unique and statistically significant contribution to the prediction. Among 200 respondents, about 70% of peoples said “Maybe” Coronavirus microorganism formed by the impact of climate change, and it’s some factor. It is also found from the correlation analysis that the epidemic effects of COVID-19 will high on Bangladesh, if immigrant persons come, if Curfew doesn’t issue, if peoples are not conscious, if peoples are not properly using mask and hand gloves, if they are not maintaining social distance and lock down rules. In the finding that, in the polar region, there are many ice stacks where thousands of years ago, the animals are dead but the virus and bacteria are in a state of sleep. As the heat increases, all glaciers and permafrost start to melt in the Polar region. As a result, many types of viruses, bacteria are starting to live. These viruses including Coronavirus will be mixed with different environmental elements such as water, biodiversity. This will easily affect biodiversity and other animals including humans. Above all Climate change may play a significant role in the transmission of many infectious diseases including Coronavirus. Community responses are important for outbreak management during the early phase of major preventive options

The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) Scoring: the Diagnostic and Potential Prognostic Role

BACKGROUND: Necrotizing fasciitis (NF) is a devastating soft tissue infection associated with potentially poor outcomes. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score has been introduced as a diagnostic tool for NF. We aimed to evaluate the prognostic value of LRINEC scoring in NF patients. METHODS: A retrospective analysis was conducted for patients who were admitted with NF between 2000 and 2013. Based on LRINEC points, patients were classified into (Group 1: LRINEC /= 6). The 2 groups were analyzed and compared. Primary outcomes were hospital length of stay, septic shock and hospital death. RESULTS: A total of 294 NF cases were identified with a mean age 50.9 +/- 15 years. When compared to Group1, patients in Group 2 were 5 years older (p = 0.009), more likely to have diabetes mellitus (61 vs 41%, p \u3c 0.001), Pseudomonas aeruginosa infection (p = 0.004), greater Sequential Organ Failure Assessment (SOFA) score (11.5 +/- 3 vs 8 +/- 2, p = 0.001), and prolonged intensive care (median 7 vs 5 days) and hospital length of stay (22 vs 11 days, p = 0.001). Septic shock (37 vs. 15%, p = 0.001) and mortality (28.8 vs. 15.0%, p = 0.005) were also significantly higher in Group 2 patients. Using Receiver operating curve, cutoff LRINEC point for mortality was 8.5 with area under the curve of 0.64. Pearson correlation analysis showed a significant correlation between LRINEC and SOFA scorings (r = 0.51, p \u3c 0.002). DISCUSSION: Early diagnosis, simplified risk stratification and on-time management are vital to achieve better outcomes in patients with NF. CONCLUSIONS: Beside its diagnostic role, LRINEC scoring could predict worse hospital outcomes in patients with NF and simply identify the high-risk patients. However, further prospective studies are needed to support this finding

The Global Alliance for Infections in Surgery: Defining a Model for Antimicrobial Stewardship-Results From an International Cross-Sectional Survey

BACKGROUND: Antimicrobial Stewardship Programs (ASPs) have been promoted to optimize antimicrobial usage and patient outcomes, and to reduce the emergence of antimicrobial-resistant organisms. However, the best strategies for an ASP are not definitively established and are likely to vary based on local culture, policy, and routine clinical practice, and probably limited resources in middle-income countries. The aim of this study is to evaluate structures and resources of antimicrobial stewardship teams (ASTs) in surgical departments from different regions of the world. METHODS: A cross-sectional web-based survey was conducted in 2016 on 173 physicians who participated in the AGORA (Antimicrobials: A Global Alliance for Optimizing their Rational Use in Intra-Abdominal Infections) project and on 658 international experts in the fields of ASPs, infection control, and infections in surgery. RESULTS: The response rate was 19.4%. One hundred fifty-six (98.7%) participants stated their hospital had a multidisciplinary AST. The median number of physicians working inside the team was five [interquartile range 4-6]. An infectious disease specialist, a microbiologist and an infection control specialist were, respectively, present in 80.1, 76.3, and 67.9% of the ASTs. A surgeon was a component in 59.0% of cases and was significantly more likely to be present in university hospitals (89.5%, p \u3c 0.05) compared to community teaching (83.3%) and community hospitals (66.7%). Protocols for pre-operative prophylaxis and for antimicrobial treatment of surgical infections were respectively implemented in 96.2 and 82.3% of the hospitals. The majority of the surgical departments implemented both persuasive and restrictive interventions (72.8%). The most common types of interventions in surgical departments were dissemination of educational materials (62.5%), expert approval (61.0%), audit and feedback (55.1%), educational outreach (53.7%), and compulsory order forms (51.5%). CONCLUSION: The survey showed a heterogeneous organization of ASPs worldwide, demonstrating the necessity of a multidisciplinary and collaborative approach in the battle against antimicrobial resistance in surgical infections, and the importance of educational efforts towards this goal

Evaluation of Green Corrosion Inhibition by Extracts of Citrus aurantium Leaves Against Carbon Steel in 1 M HCl Medium Complemented with Quantum Chemical Assessment

Employing plants as corrosion inhibitors is a physical direction to detect less expensive green friendly inhibitors. Researchers found that the Citrus aurantium leaves extracts are mixtures containing vitamins, minerals, phenolic compounds and terpenoids. The flavonoids contained in C. aurantium can be divided into four groups, including flavones, flavanones, flavonols, and anthocyanins. These compounds indicate the extracts of Citrus aurantium leaves are appropriate to be applied as green corrosion inhibitors. Extracts of Citrus aurantium leaves have been researched by utilizing EIS, gravimetric and SEM techniques as novel eco-friendly corrosion inhibitors for carbon steel in corrosive environments. Inhibition effectiveness of tested extract depends on different concentrations of extract, starting from 0 to 40% v/v. Inhibition effectiveness of 81.2% is reached at the concentration of 20% v/v of the extract in 1 M corrosive solution for three hours at 25℃. Temperature effects and activation parameters have been investigated. A theoretical investigation of Citrus aurantium leaves extract isomers as corrosion inhibitors have been done using DFT/ B3LYP density functional theory. The results shows that, in general, Citrus aurantium leaves have good inhibiting activities at relatively low concentrations. Phenolic groups of Citrus aurantium leaves were picked for examination as substituents of the four inhibitors. Hydroxyl groups of the studied extract compounds result in an increase in inhibition effectiveness, while methylation of the hydroxyl group leads to decrease in inhibitive effectiveness. Citrus aurantium leaves extracted isomers symbolize a considerable enhancement in the inhibition performance

Performance Analysis of Solar Adsorption Cooling System - Effect of Position of Heat Storage Tank

An insulated storage tank has been added with adsorption cooling system run by solar heat collected by CPC panel. It has been expected and seen that the storage tank has a vital contribution in the performance of the chiller. The storage tank is connected with a solar heat driven single stage two bed basic adsorption chillers activated with silica gel-water pair in two ways. The tank is connected in such a way that (i) the solar collectors supply hot water to the desorption bed, the outflow of the desorber is collected in the reserve tank. The reserve tank supplies water to the collector and complete the heat transfer cycle. (ii) The solar collector supply hot water which is collected in the storage tank first and then supplied to the desorber. The outflow of the desorber is carried to the collector again. Comparative studies have been conducted at the steady state for both of the systems with heat storage. It has been observed that the system is robust with design (i) while with design (ii) performance enhances beyond the sunset time with heat storage
