Antibiotic levels in water and potential risk of drugresistant bugs

first_imgReviewed by James Ives, M.Psych. (Editor)Mar 27 2019A JRC report brings together data on antibiotic levels in water, showing that small concentrations have found their way into a range of Europe’s waterbodies.Because of the threat of new drug-resistant bugs evolving when these antibiotics come into contact with bacteria present in the water, scientists are gathering evidence to better understand the potential risk.Their data confirms that the levels of antibiotic residues in drinking water are minute and do not represent a risk to human health.However, antibiotic residues can be found at higher levels in waste water, surface waters, agricultural runoff and water used for aquaculture (farms of fish, muscles, seaweed and other marine species).The report is part of JRC efforts dedicated to investigating the implications of antibiotics in water.Scientists aim to determine the minimum concentration of antibiotics that could cause resistance in bacteria, so that future limits can be based on risk assessments that take into account this potential.The report also highlights that the development and spread of antimicrobial resistance (AMR) (the phenomenon of bacteria resisting the effects of antibiotics) can be constrained if measures are taken to improve the effectiveness of wastewater treatment processes and to control the use of antibiotics in medicine and animal husbandry.Where do antibiotics end up after they’ve done their job?Antibiotics are prescribed for a vast range of bacterial infections in humans and have saved the lives of millions since their discovery.They are also given to animals as part of veterinary treatment, including to control infections in farm livestock.Resistant bacteria regularly evolve in places where antibiotics are commonly used – such as in hospitals where the MRSA ‘superbug’ (resistant to a wide range of antibiotics) is often found.On top of this, antibiotics don’t simply disappear after they’ve done their job of fighting off a bug.They are excreted from the body and so there’s also a risk of similar bugs proliferating in water in treatment plants, in manure and slurry, and in the environment if the concentration of antibiotics is high enough to select for their survival.The prevalence of antibiotic use has led to growing concern over the spread of AMR. In Europe, about 25000 people die of infections from antimicrobial-resistant bacteria every year.It’s also estimated that AMR costs the EU €1.5 bn per year in healthcare costs and productivity losses.Which antibiotics? How are they monitored?Looking at data on 45 antibiotics from 13 countries worldwide, the report’s authors found sulfamethoxazole, trimethoprim and ciprofloxacin to be the three most frequently found in the water that flows out of waste water treatment plants.Most of the data came from Europe (79.2%) and, for the antibiotics detected, the concentrations ranged up to 1 µg/L (one millionth of a gram per litre).Related StoriesA bacterium may limit cardiovascular risks of 1 in 2 people, study showsRaw meat can act as reservoir for bacteria associated with hospital infections’Scissors’ component of CRISPR/Cas9 sometimes gets stuckThese medicines are all commonly prescribed for urinary tract infections, while ciprofloxacin is also prescribed for ear and chest infections.Similar concentrations of antibiotics were also reported in surface waters, despite the fact that a reduction in their levels might reasonably have been expected due to the dilution of these substances as effluents run into rivers and lakes.Ciprofloxacin is included alongside amoxicillin, erythromycin, azithromycin and clarithromycin on the Watch List monitoring program under the EU’s Water Framework Directive, which gathers data on substances that may pose a risk at EU level.The analytical methods used have to be able to detect concentrations as low as between 0.019 and 0.089 µg/L, corresponding to concentrations considered not to have direct effects on aquatic organisms such as algae, crustacean and fish.Antibiotics in fish farms?The report notes that therehasso far beenlittle research into the use and effects of antibiotics in the aquaculturesector.In Europe,the use of antibiotics inallanimalfarming activities, including aquaculture,isregulatedby specific legislation.Aquaculture products(as well as any products from the animal farming systems)must not contain pharmacologically active substances abovean established Maximum Residue Limit.Efficient monitoring at EU levelreliesonsurveillance programmesimplementedin the EU Member States, andrelevant dataaremadeavailableto the Commission.Aquaculture is the fastest growing food-producing sector and it is estimated to account for approximately half of the total food supply coming from fish.While it is necessary to prevent bacterial diseases in aquaculture products, the use of vaccines could lessen the need for chemicals and antibiotics in this sector, on condition that vaccines against the most relevant diseases are registered and accessible in all EU member states.BackgroundIn June 2017 the Commission adopted the EU One Health Action Plan against AMR. The key objectives of this new plan include:1. Making the EU a best practice region2. Boosting research, development and innovation3. Shaping the global agendaThe Commission has also adopted the first deliverables of the plan, for example the EU Guidelines on the prudent use of antimicrobials in human health.The guidelines aim to reduce inappropriate use and promote prudent use of antimicrobials in people. They target all actors who are responsible for or play a role in antimicrobial use.The Commission also recently adopted a Strategic Approach to Pharmaceuticals in the Environment – a set of actions addressing the multifaceted challenges that the release of pharmaceuticals poses to the environment.

Effective methods for automated design of complex technical objects and systems

The content is provided for information purposes only. When solving multicriteria optimization problems, the complexity of computations substantially increases when it is necessary to find several (or the entire set of) effective options. Finding even one compromise option requires a significant amount of computations, while the definition of several (or the entire set of) effective options becomes a problem of exceptional computational complexity.To overcome the computational complexity of multicriteria problems, Professor Strongin’s research team proposed a two-fold approach. First, effective global search algorithms developed within the framework of the information-statistical theory of multi-extremal optimization will be used for solving optimization problems. Second, when performing calculations, all the search information received during the calculation will be used to the greatest possible extent. On the whole, the re-use of search information will result in a continuously decreasing amount of calculation when searching for the next effective options.Computational experiments performed by Lobachevsky University scientists show that the proposed approach makes it possible to reduce more than a hundredfold the amount of required computations when searching for the next effective solution.A good example of practical application of this approach is the optimized profile of railway wheels. This result was obtained jointly with the colleagues from the Technical University of Delft (the Netherlands).”Our calculations show that the proposed optimized profile of train wheels provides an increase in the wheel life to 120 thousand km (more than five times compared with the wheel of the original profile), while increasing the maximum permissible speed from 40 m/sec to 60 m/sec,” notes Professor Strongin. Explore further So it comes as no surprise that researchers at the Lobachevsky University are actively involved in the research of models and methods for making optimal decisions when solving complex problems. A team of scientists under Professor Roman Strongin has proposed a large number of approaches to solving global (multi-extremal) optimization problems, including linear programming of the problems of unconditional optimization, problems of nonlinear programming, and many others.With these approaches, it is possible to solve many problems of optimal decision-making by using some key properties. For example, it is assumed in linear programming problems that all the existing dependencies in the optimization problem are linear. However, existing approaches do not fully cover all possible tasks for making optimal decisions.According to Professor Victor Gergel, a leading member of the research team at the Lobachevsky University, the distinguishing feature of this class of problems is the assumption of multi-extremality of optimized efficiency criteria, for which the optimality among close variants does not necessarily mean the optimality among all possible alternatives.”This determines the complexity of global optimization problems: in order to prove the optimality of the chosen option, one must show that this particular option is the best in the whole range of possible solutions,” says Victor Gergel.At an additional level of complexity, it becomes possible to have several simultaneous performance criteria, which is important in practical applications. In fact, how can engineers choose one quality criterion when developing a new car? Most likely, it is possible to specify several individual partial indicators, such as weight, cost, maximum speed, etc. However, the partial efficiency criteria are, as a rule, contradictory, and no available options would be the best in all respects (the fastest car will not be the cheapest).Therefore, the solution of multicriteria problems is reduced to finding effective compromise options that cannot be improved simultaneously with respect to all the partial criteria. At the same time, it may be necessary in the course of calculations to find several effective solutions. In the extreme case, this may be an entire set of undominated options. Diagonal methods for expensive global optimization In almost any field of human activity, people choose optimal options from a great variety of possible alternatives. When designing new devices, products and systems, researchers and engineers always strive to ensure that their systems have the best characteristics and are economically viable. Thus, for example, a new car being developed must be fast, consume a minimum amount of fuel, be reliable and, in addition, it should not be too expensive.

Kamal Nath govt would even transfer land sky BJP on transfer of

first_img Next Kamal Nath govt would even transfer land & sky: BJP on transfer of police dogs, handlers in MPThe Congress government’s latest move of transferring the dog-squad has drawn scathing criticism from BJP which is using the opportunity to attack the Kamal Nath government in Madhy Pradesh.advertisement Asian News International BhopalJuly 13, 2019UPDATED: July 13, 2019 12:22 IST Three sniffers, one each from Chhindwara, Satna and Betul have been shifted to CM Kamal Nath’s house in Bhopal. (File photo: PTI)In a move that has invoked sharp criticism from Bharatiya Janata Party (BJP) leaders, the Congress-led Madhya Pradesh government has issued an order transferring 46 police dog handlers across the state along with their canines.According to the order, handlers of tracker, sniffer and narco dogs from 23 Battalion Dog Squad have been given new postings in different districts of the state and have been ordered to rejoin immediately along with their dogs.In the latest postings, three sniffers, one each from Chhindwara, Satna and Betul have been shifted to Chief Minister Kamal Nath’s house in Bhopal.The latest step of transferring the dog-squad has drawn scathing criticism from rival BJP which is using the opportunity to attack the government.Taking a dig at the MP government, the BJP’s state vice president Vijesh Lunawat tweeted, “The Great Kamal Nath government did not spare even dogs from the transfer business. Dog squad transferred in Madhya Pradesh.”BJP MLA Rameshwar Sharma invoked the issue of transfer of dogs to allege that the Congress government would even sell land and sky if they could.”Congress government should have at least left the dogs. The police department has transferred dogs en masse. If it was possible for Kamal Nath government and someone was ready to pay the price, they would even transfer land and sky,” Sharma said in a tweet in Hindi.On Friday, the BJP cornered the Madhya Pradesh government for erroneously issuing transfer order of a ‘Sarpanch’ instead of Panchayat Secretary.Referring to a July 5 order of Rewa District Panchayat, Devtalab MLA Girish Gautam said that instead of transferring Rewa district panchayat Shivpura’s in-charge Vibha Dwivedi, Sarpanch Bihari Lal Patel was transferred.”The minister has become so busy that he has transferred a Sarpanch instead of Panchayat Secretary,” he said.It may be noted that a Sarpanch is elected by people and is not entitled to be transferred by the state government.The BJP has in the past alleged that a “transfer racket” was flourishing in the government under Chief Minister Kamal Nath.”A transfer racket is flourishing in the Congress government under Kamal Nath and officials are at the centre of it. They are engaged in seat sale. Officials bid for seats. Congress is not running a government but a ‘hawala udyog’,” the BJP MLA from Narela Vishwas Sarang had alleged in June this year.READ | Mumbai Police officer saves dog from drowning during floods.
