    The development of antibiotic resistance is a major problem for mankind and results in fatal consequences on a daily basis across the globe. There are a number of reasons for this situation including increasing globalization with worldwide travel, health tourism, over use and ineffective use (both in man and animals), and counterfeiting of the antimicrobial drug products we have available currently. Although there are huge economical, demographic, legal and logistic differences among the global communities, there are also differences regarding the best approach to dealing with antibiotic resistance. However, as resistant bacteria do not respect international borders, there is clearly a need for a global strategy to minimize the spread of antibiotic resistance, to optimize the use of antibiotics, and to facilitate the development of new and effective medications. This commentary provides an insight into the issues and some of the ongoing programs to ensure an effective treatment for the future. PMID:27397433

    The unrestricted use of antibiotics has resulted in rapid acquisition of antibiotic resistance (AR) and spread of multidrug-resistant (MDR) bacterial pathogens. With the advent of next-generation sequencing technologies and their application in understanding MDR pathogen dynamics, it has become...... imperative to unify AR gene data resources for easy accessibility for researchers. However, due to the absence of a centralized platform for AR gene resources, availability, consistency, and accuracy of information vary considerably across different databases. In this article, we explore existing AR gene...... data resources in order to make them more visible to the clinical microbiology community, to identify their limitations, and to propose potential solutions....

    The Endophthalmitis Vitrectomy Study (EVS) provided ophthalmologists with evidence-based management strategies to deal with endophthalmitis for the first time. However, since the completion of the EVS, numerous unresolved issues remain. The use of oral antibiotics has important implications for the ophthalmologist, particularly in the prophylaxis and/or management of postoperative, posttraumatic, or bleb-associated bacterial endophthalmitis. One can reasonably conclude that significant intraocular penetration of an antibiotic after oral administration may be a property unique to the newer-generation fluoroquinolones. Prophylactic use of mupirocin nasal ointment resulted in significant reduction of conjunctival flora with or without preoperative topical 5% povidone-iodine preparation. Ocular fungal infections have traditionally been very difficult to treat due to limited therapeutic options both systemically and intravitreally. Because of its broad spectrum of coverage, low MIC90 levels for the organisms of concern, good tolerability, and excellent bioavailability, voriconazole through various routes of administration may be useful to the ophthalmologist in the primary treatment of or as an adjunct to the current management of ocular fungal infections.

    Full Text Available Considering the emergence of both Gram negative and Gram positive resistant bacterial strains in the recent years, makes it more prominent to utilize the existed antibiotics in an appropriate and justified way in the treatment of drug resistant infections. Many of the agents currently used to treat bacterial, viral and fungal infections do not need to be pharmacokinetically monitored; it means we do not require their serum levels in order to adjust the dose in a routine manner. Examples of these antibiotics are penicillins, cephalosporins, macrolides, tetracyclines, fluoroquinolones, etc. Of course these agents need dose adjustment based on renal and hepatic functions. On the other hand there are antibiotics which need to be monitored through their serum levels because of three main following reasons: 1-      To avoid overdosing patient and reduce the incidence of toxicities. 2-      To avoid underdosing patient, this may lead to the emergence of resistant strains and treatment failure. 3-      To optimize the dose of antibiotic to achieve the bactericidal or bacteriostatic effects needed to suppress the infective agent. At this point, we are using vancomycin as a broad spectrum Gram positive agent and aminoglycosides both for the synergism for Gram positive coverage and also for treatment of Gram negative infection in combination with other agents. According to the guidelines published by the accredited organizations like Infectious Diseases Society of America (IDSA and American Society of Healthcare Pharmacists (ASHP, it is crucially important to perform therapeutic drug monitoring (TDM for both vancomycin and aminoglycosides based on their serum levels for all patients on these agents. In the other word, it is a wrong antibiotic therapy without monitoring the levels. Almost in all medical centers nationwide including teaching hospitals the clinicians prescribe vancomycin very often and aminoglycosides like gentamicin and

    International Nuclear Information System (INIS)

    Power and energy, with particularly electricity remains the pivot of economical and social development of any country. In view of this fact, a research on how renewable energy resources can solve Nigeria power and energy needs was carried out. It has identified main issues such as inconsistence government policies, corruptions and lack of fund hindering the development of renewable and power sectors for sustainable energy supply. The capacity of alternative energy resources and technology [hydropower, wind power, biomass, photovoltaic (solar), and geothermal power] to solve Nigerian energy crisis cannot be over-emphasized as some countries of the world who have no petroleum resources, utilizes other alternatives or options to solves their power and energy requirement. This paper reviews the prospects, challenges and solutions to Nigeria energy needs using renewable sources for development as it boost industrialization and create job opportunities

    Full Text Available Nuclear power is a proven technology that has served humanity for the past fifty years. It has provided electricity for several countries and shall continue to serve as a viable base load source of electric power. The need for skilled human resources for nuclear practice cannot be overlooked in the quest of any nation to adopt the technology. The Ghana Atomic Energy Commission and the University of Ghana in collaboration with the International Atomic Energy Agency have thus started a Graduate School of Nuclear and Allied Sciences to provide the human resources needed for nuclear power generation in Ghana. The School currently offers second degree courses as well as doctor of philosophy courses. Financial, land and water resource needs for nuclear power generation have been discussed. Availability of the national grid due to the deregulation of the electric power sector has also been discussed. Nuclear Fuel availability has been discussed along with the steps Ghana has to go through to obtain the technology to her development. The legal and legislative framework for nuclear power generation has also been presented. The programs currently available from the IAEA to assist Ghana to develop nuclear power have also been discussed. Conclusions have been drawn based on the discussions made.

  1. Antibiotic Prophylaxis in Severe Acute Pancreatitis: Do We Need More Meta-Analytic Studies?

    Directory of Open Access Journals (Sweden)

    Raffaele Pezzilli

    2009-03-01

    Full Text Available Several guidelines on acute pancreatitis suggest that carbapenems should be used prophylactically and should be continued for 14 days, and that the development of infected necrosis should be assessed using fine-needle aspiration and the sample should be cultured for germ isolation and characterization [1]. In routine clinical practice, antibiotics are used to cure both extrapancreatic infections which appear during the course of acute pancreatitis and infected pancreatic necrosis and also as a prophylaxis in those patients who have pancreatic necrosis in order to prevent possible infection from the necrosis. In the treatment of extrapancreatic infections, the most used antibiotics were cephalosporins whereas carbapenems, glycopeptides and antifungal antibiotics were the most used antibiotics in the treatment of proven infected pancreatic necrosis [2]. Moreover, there are very few topics in pancreatology which cause as much debate as that regarding the utility of antibiotic prophylaxis in severe acute pancreatitis. There are very few human randomized studies and there are more meta-analyses published than studies published. Of course, the cost of a meta-analysis is much less than carrying out a study on the efficacy of antibiotics in severe acute pancreatitis.

    The social sciences have become increasingly important in understanding natural resource management contexts and audiences, and are essential in design and delivery of effective and durable management strategies. Yet many agencies and organizations do not have the necessary resource management. We draw on the textbook definition of HD: how and why people value natural resources, what benefits people seek and derive from those resources, and how people affect and are affected by those resources and their management (Decker, Brown, and Seimer 2001). Clearly articulating how HD information can be used and integrated into natural resource management planning and decision-making is an important challenge faced by the HD field. To address this challenge, we formed a collaborative team to explore the issue of HD capacity-building for natural resource organizations and to advance the HD field. We define HD capacity as activities, efforts, and resources that enhance the ability of HD researchers and practitioners and natural managers and decision-makers to understand and address the social aspects of conservation. Specifically, we sought to examine current barriers to integration of HD into natural resource management, knowledge needed to improve HD capacity, and existing HD tools, resources, and training opportunities. We conducted a needs assessment of HD experts and practitioners, developed a framework for considering HD activities that can contribute both directly and indirectly throughout any phase of an adaptive management cycle, and held a workshop to review preliminary findings and gather additional input through breakout group discussions. This paper provides highlights from our collaborative initiative to help frame and inform future HD capacity-building efforts and natural resource organizations and also provides a list of existing human dimensions tools and resources.

    Full Text Available Abstract Background Usefulness of prophylactic antibiotics following tube thoracostomy remains controversial in the literature. In this study, we aimed to investigate the consequences of closed tube thoracostomy for primary spontaneous pneumothorax without the use of antibiotics. Methods One-hundred and nineteen patients underwent tube thoracostomy for primary spontaneous pneumothorax. None of them received prophylactic antibiotic treatment. Eight patients with prolonged air leak undergoing either video assisted thoracoscopic surgery or thoracotomy were excluded. Results Of the remaining 111 (104 male and 7 female, 28 (25% patients developed some induration around the entry site of chest tube that settled without further treatment. White blood cell count was high without any other evidence of infection in 12 (11% patients and returned to its normal levels before discharge home in all. There was also some degree of fever not lasting for more than 48 hours in 8 (7% patients. Bacterial cultures from suspected sites did not reveal any significant growth in these patients. Conclusion Prophylactic antibiotic treatment seems avoidable during closed tube thoracostomy for primary spontaneous pneumothorax. This policy was not only cost-effective but also prevented our patients from detrimental properties of unnecessary antibiotic use, such as development of drug resistance and undesirable side effects.

  4. The urgent need for risk assessment on the antibiotic resistance spread via sewage sludge land application.

    2016-02-01

    Sewage sludge is an ever-increasing by-product of the wastewater treatment process frequently used as a soil fertiliser. To control its quality and prevent any possible hazardous impact of fertilisation, some mandatory limits of heavy metal content have been established by the European Commission (Sewage Sludge Directive). However, since the implementation of the limits, new emerging contaminants have been reported worldwide. Regardless of the wastewater treatment process, sewage sludge contains antibiotics, antibiotic-resistant bacteria and antibiotic resistance genes, which can be released into the environment through its land application. Such a practice may even boost the dissemination and further development of antibiotic resistance phenomenon - already a global problem challenging modern medicine. Due to the growing pharmaceutical pollution in the environment, the time is ripe to assess the risk for the human and environmental health of sewage sludge land application in the context of antibiotic resistance spread. In this review we present the current knowledge in the field and we emphasise the necessity for more studies. PMID:26646979

  5. Resource competition in plant invasions: emerging patterns and research needs

    Margherita eGioria

    2014-09-01

    Full Text Available Invasions by alien plants provide a unique opportunity to examine competitive interactions among plants. While resource competition has long been regarded as a major mechanism responsible for successful invasions, given a well-known capacity for many invaders to become dominant and reduce plant diversity in the invaded communities, few studies have measured resource competition directly or have assessed its importance relatively to that of other mechanisms, at different stages of an invasion process. Here, we review evidence comparing the competitive ability of invasive species vs. that of co-occurring native plants, along a range of environmental gradients, showing that many invasive species have a superior competitive ability over native species, while invasive congeners are not necessarily competitively superior over native congeners, nor alien dominants are better competitors than native dominants. We discuss how the outcomes of competition depend on a number of factors, such as the heterogeneous distribution of resources, the stage of the invasion process, as well as phenotypic plasticity and evolutionary adaptation, which may result in increased or decreased competitive ability in both invasive and native species. Competitive advantages of invasive species over natives are often transient and only important at the early stages of an invasion process. It remains unclear how important resource competition is relative to other mechanisms (competition avoidance via phenological differences, niche differentiation in space associated with phylogenetic distance, recruitment and dispersal limitation, indirect competition, and allelopathy. We then identify the conceptual and methodological issues characterizing competition studies in plant invasions, and we discuss future research needs, including examinations of resource competition dynamics and of the impact of global environmental changes on competitive interactions between invasive and native

    Contamination of waste effluent from hospitals and intensive food animal production with antimicrobial residues is an immense global problem. Antimicrobial residues exert selection pressures that influence the acquisition of antimicrobial resistance and virulence genes in diverse microbial populations. Despite these concerns there is only a limited understanding of how antimicrobial residues contribute to the global problem of antimicrobial resistance. Furthermore, rapid detection of emerging bacterial pathogens and strains with resistance to more than one antibiotic class remains a challenge. A comprehensive, sequence-based genomic epidemiological surveillance model that captures essential microbial metadata is needed, both to improve surveillance for antimicrobial resistance and to monitor pathogen evolution. Escherichia coli is an important pathogen causing both intestinal [intestinal pathogenic E. coli (IPEC)] and extraintestinal [extraintestinal pathogenic E. coli (ExPEC)] disease in humans and food animals. ExPEC are the most frequently isolated Gram negative pathogen affecting human health, linked to food production practices and are often resistant to multiple antibiotics. Cattle are a known reservoir of IPEC but they are not recognized as a source of ExPEC that impact human or animal health. In contrast, poultry are a recognized source of multiple antibiotic resistant ExPEC, while swine have received comparatively less attention in this regard. Here, we review what is known about ExPEC in swine and how pig production contributes to the problem of antibiotic resistance. PMID:27379026

    The report identifies the energy needs, uses, and resources in the developing countries of the world and examines the energy options available to them for their continued social and economic growth. If traditional patterns of development are to continue, oil consumption in the non-OPEC LDCs will grow steadily to become comparable with current U.S. consumption between 2000 and 2020. Attempts to exploit indigenous hydrocarbon resources even in those LDCs with untapped reserves will be limited by shortages of capital and technical manpower. In the absence of major actions to replace noncommercial fuels or to increase the effectiveness with which they are used, a large fraction of the 3 to 4 billion LDC rural population in the year 2000 will not be able to raise their energy usage above subsistence levels. There is a wide variety of solutions to these problems, many of them emerging directly from the changed economics of energy. For example, most LDCs have not adequately explored and developed their own indigenous resources; in virtually all energy conversion and utilization processes there are opportunities for improvements in efficiency and substitution of renewable energy forms. In virtually all these areas there are opportunities for effective assistance activities.

    Geoscience faculty, departments, and programs play an important role in preparing future geoscience professionals. One challenge is supporting the diversity of student goals for future employment and the needs of a wide range of potential employers. Students in geoscience degree programs pursue careers in traditional geoscience industries; in geoscience education and research (including K-12 teaching); and opportunities at the intersection of geoscience and other fields (e.g., policy, law, business). The Building Strong Geoscience Departments project has documented a range of approaches that departments use to support the development of geoscience majors as professionals (serc.carleton.edu/departments). On the Cutting Edge, a professional development program, supports graduate students and post-doctoral fellows interested in pursuing an academic career through workshops, webinars, and online resources (serc.carleton.edu/NAGTWorkshops/careerprep). Geoscience departments work at the intersection of student interests and employer needs. Commonly cited program goals that align with employer needs include mastery of geoscience content; field experience; skill in problem solving, quantitative reasoning, communication, and collaboration; and the ability to learn independently and take a project from start to finish. Departments and faculty can address workforce issues by 1) implementing of degree programs that develop the knowledge, skills, and attitudes that students need, while recognizing that students have a diversity of career goals; 2) introducing career options to majors and potential majors and encouraging exploration of options; 3) advising students on how to prepare for specific career paths; 4) helping students develop into professionals, and 5) supporting students in the job search. It is valuable to build connections with geoscience employers, work with alumni and foster connections between students and alumni with similar career interests, collaborate with

    A detailed analysis was conducted to determine the adequacy of the total research efforts regarding the potential environmental impacts related to the exploration, drilling, production, and transmission stages of vapor-dominated, liquid-dominated, geopressured, and hot-dry-rock geothermal resources. The following environmental considerations were selected and analyzed in detail: air emissions (hydrogen sulfide, ammonia, mercury, boron, radon, etc.); liquid emissions (brine, and toxic chemicals); land subsidence; seismic activity; and noise. Following the definition of the problem and the assessment of the past and ongoing research efforts, environmental research needs were then recommended based on: (1) the severity of the environmental problems as perceived by literature and contacts with the research community; (2) probability of occurrence; (3) and the research dependency for a solution to that particular problem. The recommended research needs consisted of: (1) an evaluation of the past and ongoing research efforts to ascertain gaps in knowledge for a particular pollutant, process, or control technology; (2) baseline studies of air, soil, water, and ecology around the existing geothermal facilities and in the locations scheduled for future geothermal development; (3) need for the development of appropriate models for predicting concentration and dispersion of pollutants; (4) development of predictive models for potential health and environmental effects associated with geothermal operations; and (5) development of appropriate control technology to destroy, remove or reduce harmful emissions in order to prevent the occurrence of environmental and health hazards and to comply with existing standards and criteria.

    Full Text Available Introduction: The etiology of urinary tract infections (UTIs and the antibiotic resistance of uropathogens have been changing over the past years. This retrospective study was conducted to survey the resistance pattern of Gram-negative uropathogens to first-line agents for UTIs; this would be helpful for the clinicians to facilitate the empiric treatment and management of patients with UTI and maybe useful for the formulation of guidelines of antibiotic policies. Materials and Methods: Isolated uropathogens were tested against ampicillin-sulbactam, amikacin, ceftriaxone, cefotaxime, cefoperazone, gentamicin, norfloxacin, ofloxacin, piperacillin-tazobactam, and imipenem. Result: A total of 2,146 urine samples were cultured, of which 448 samples were positive for Gram-negative bacilli. The most common Gram-negative isolate was Esherichia coli (52% followed by Klebsiella pneumoniae (17.6% and Pseudomonas aeruginosa (12.9%. E. coli was found to be most resistant to ampicillin-sulbactam (90.1%, followed by norfloxacin (76.3%, and most sensitive to imipenem. P. aeruginosa was least resistant to amikacin (27.5%. Overall resistance to imipenem is less than 20% among the Gram-negative uropathogens except Acinetobacter spp. and P. aeruginosa. Conclusion: Ofloxacin and amikacin are recommended as the drugs of choice for the empirical treatment of UTI, whereas specific treatment should be based on the etiological agent isolated in the urine culture. There is a strict need for developing specific guidelines for antibiotic prescriptions for UTI in India.

    Energy "powers" our life, and energy consumption correlates strongly with our standards of living. The developed world has become accustomed to cheap and plentiful supplies. Recently, more of the developing world populations are striving for the same, and taking steps towards securing their future energy needs. Competition over limited supplies of conventional fossil fuel resources is intensifying, and more challenging environmental problems are springing up, especially related to carbon dioxide (CO 2) emissions. There is strong evidence that atmospheric CO 2 concentration is well correlated with the average global temperature. Moreover, model predictions indicate that the century-old observed trend of rising temperatures could accelerate as carbon dioxide concentration continues to rise. Given the potential danger of such a scenario, it is suggested that steps be taken to curb energy-related CO 2 emissions through a number of technological solutions, which are to be implemented in a timely fashion. These solutions include a substantial improvement in energy conversion and utilization efficiencies, carbon capture and sequestration, and expanding the use of nuclear energy and renewable sources. Some of these technologies already exist, but are not deployed at sufficiently large scale. Others are under development, and some are at or near the conceptual state. © 2010 Elsevier Ltd.

    Economic analysis is founded on the assumption that resources are limited and that should be used in a way that maximizes the benefits gained. Pharmacoeconomics extends these assumptions to drug treatment. Therefore, a full pharmacoeconomic analysis must consider two or more alternative treatments and should be founded on measurement of incremental cost, incremental efficacy, and the value of successful outcome. Antibiotic policy based only on administrative restrictions is failed, instead of it disease formularies and infectologist consultation system are needed. Equally important are various programmes that encourage the cost-conscious use of the antibiotics chosen. Some of the methods evaluated in the literature include: streamlining from combination therapy to a single agent, early switching from parenteral to oral therapy, initiating treatment with oral agents, administering parenteral antibiotic at home from outset of therapy, and antibiotic streamlining programmes that are partnered with infectious disease physicians. The solution is the rational and adequate use of antibiotics, based on the modern theory and practice of antibiotic policy and infection control, that cannot be carried out without the activities of experts in this field.

    2011-01-01

    Full Text Available In an era of spiraling health care costs and limited resources, policy makers and health care payers are concerned about the cost effectiveness of antibiotics. The aim of this study is to draw on published economic evaluations with a view to identify and illustrate the factors affecting the cost effectiveness of antibiotic treatment of bacterial infections. The findings indicate that the cost effectiveness of antibiotics is influenced by factors relating to the characteristics and the use of antibiotics (i.e., diagnosis, comparative costs and comparative effectiveness, resistance, patient compliance with treatment, and treatment failure and by external factors (i.e., funding source, clinical pharmacy interventions, and guideline implementation interventions. Physicians need to take into account these factors when prescribing an antibiotic and assess whether a specific antibiotic treatment adds sufficient value to justify its costs.

    In this third article of the three-part series, management of skin and soft tissue infections is reviewed with emphasis on new information on methicillin-resistant Staphylococcus aureus. Due to changes in the evolution of methicillin-resistant Staphylococcus aureus clones, previous distinctions between healthcare-acquired methicillin-resistant Staphylococcus aureus and community-acquired methicillin-resistant Staphylococcus aureus are currently much less clinically relevant. Many nosocomial cases of methicillin-resistant Staphylococcus aureus infection are now caused by community-acquired methicillin-resistant Staphylococcus aureus, with changing patterns of antibiotic susceptibility and resistance. Also reviewed are clinical scenarios where antibiotics may not be needed and suggestions for optimal use of antibiotic therapy for dermatologie conditions, including recommendations on perioperative antibiotic use.

  15. Water-resources programs and hydrologic-information needs, Marion County, Indiana, 1987

    Science.gov (United States)

    Duwelius, R.F.

    1990-01-01

    Water resources are abundant in Marion County, Indiana, and have been developed for public and industrial supply, energy generation, irrigation, and recreation. The largest water withdrawals are from surface water, and the two largest water uses are public supply and cooling water for electrical-generating plants. Water-resources programs in the county are carried out by Federal, State and local agencies to address issues of surface and groundwater availability and quality. The programs of each agency are related to the functions and goals of the agency. Although each agency has specific information needs to fulfill its functions, sometimes these needs overlap, and there are times when the same hydrologic information benefits all. Overlapping information needs and activities create opportunities for interagency coordination and cooperation. Such cooperation could lead to a savings of dollars spent on water-resources programs and could assure an improved understanding of the water resources of the county. Representatives from four agencies-- the Indiana Department of Environmental Management, the Indiana Department of Natural Resources, the Indianapolis Department of Public Works, and the U.S. Geological Survey--met four times in 1987 to describe their own water-resources programs, to identify hydrologic-information needs, and to contact other agencies with related programs. This report presents the interagency findings and is intended to further communication among water resource agencies by identifying current programs and common needs for hydrologic information. Hydrologic information needs identified by the agency representatives include more precise methods for determining the volume of water withdrawals and for determining the volume of industrial and municipal discharges to surface water. Maps of flood-prone areas need to be updated as more of the county is developed. Improved aquifer maps of the inter-till aquifers are needed, and additional observation

    Landry Michel D

    2011-10-01

    Full Text Available Abstract Background Human resources for rehabilitation are often a neglected component of health services strengthening and health workforce development. This may be partly related to weaknesses in the available research and evidence to inform advocacy and programmatic strategies. The objective of this study was to quantitatively describe the global situation in terms of supply of and need for human resources for health-related rehabilitation services, as a basis for strategy development of the workforce in physical and rehabilitation medicine. Methods Data for assessing supply of and need for rehabilitative personnel were extracted and analyzed from statistical databases maintained by the World Health Organization and other national and international health information sources. Standardized classifications were used to enhance cross-national comparability of findings. Results Large differences were found across countries and regions between assessed need for services requiring health workers associated to physical and rehabilitation medicine against estimated supply of health personnel skilled in rehabilitation services. Despite greater need, low- and middle-income countries tended to report less availability of skilled health personnel, although the strength of the supply-need relationship varied across geographical and economic country groupings. Conclusion The evidence base on human resources for health-related rehabilitation services remains fragmented, the result of limited availability and use of quality, comparable data and information within and across countries. This assessment offered the first global baseline, intended to catalyze further research that can be translated into evidence to support human resources for rehabilitation policy and practice.

  1. Resource manager information needs regarding hydrologic regime shifts for the North Pacific Landscape Conservation

    2014-01-01

    Landscape Conservation Cooperatives (LCCs) are a network of 22 public-private partnerships, defined by ecoregion, that share and provide science to ensure the sustainability of land, water, wildlife, and cultural resources in North America. LCCs were established by the U.S. Department of the Interior (DOI) in recognition of the fact that response to climate change must be coordinated on a landscape-level basis because important resources, ecosystem processes, and resource management challenges extend beyond most of the boundaries considered in current natural resource management. The North Pacific LCC (NPLCC) covers the range of the Pacific coastal temperate rainforest, including an area of 528,360 km2 spanning 22 degrees of latitude from the Kenai Peninsula, Alaska, to Bodega Bay, California. The coverage area includes parts of four States, two Canadian provinces, and more than 100 Tribes and First Nation language groups. It extends from alpine areas at the crest of coastal mountains across subalpine, montane, and lowland forests to the nearshore marine environment. This wide range of latitudes and elevation zones; terrestrial, freshwater, and marine habitats; and complex jurisdictional boundaries hosts a diversity of natural resources and their corresponding management issues are equally diverse. As evidenced by the Science and Traditional Ecological Knowledge (S-TEK) Strategy guiding principles, identifying and responding to the needs of resource managers is key to the success of the NPLCC. To help achieve this goal of the NPLCC, the U.S. Geological Survey (USGS) has organized several workshops with resource managers and resource scientists to identify management information needs relevant to the priority topics identified in the S-TEK Strategy. Here, we detail the results from a first workshop to address the effects of changes in hydrologic regime on rivers, streams, and riparian corridors. The workshop focused on a subset of the full NPLCC geography and was

  2. Final report: Skills needs in the resource-based sectors in Atlantic Canada

    International Nuclear Information System (INIS)

    Skills requirements in the resource industries in Atlantic Canada were put under the microscope at this conference. One of the objectives was to show that while the resource-based industries may not undertake extensive research and development, they are employing increasingly sophisticated technology which places increasing emphasis on the need for skilled personnel. Participants at the conference concluded that Atlantic Canada has the means to meet increasing demand for skilled workers in the resource sectors, and that the post-secondary educational system appears to have established a good rapport with the industries to ensure that the programs are meeting the sectors' changing needs. The oil and gas sector is an exception in that it is new to the area, combined with the fact that it has placed emphasis not only on skilled but skilled and experienced personnel from the start. There is also a paucity of training programs in sustainable development which is expected to become the dominant issue for resource management personnel in the next century. New skills are required to deal with this issue and post-secondary institutions of learning and the resource-based sectors will have to work together to develop the skills such as understanding ecosystem management problems and communicating with the public. Atlantic Canada cannot afford not to find a path to sustainability through the application of science and technology to management, knowledgeable extraction, and imaginative transformation of natural resources. 28 refs., 2 tabs

    1999-01-01

    This report provides an overview of the results of the Vital the Nicaraguan Water Resources Management Initiative, Issues process as implemented for a collaborative effort between the Nicaraguan Ministry of Environment and Natural Resources and Sandia National Laboratories. This initiative is being developed to assist in the development of an efficient and sustainable water resources management system for Nicamgua. The Vital Issues process was used to provide information for developing a project that will develop and implement an advanced information system for managing Nicaragua's water resources. Three Vital Issues panel meetings were convened to 1) develop a mission statement and evaluation criteria for identifying and ranking the issues vital to water resources management in Nicaragua 2) define and rank the vital issues; and 3) identify a preliminary list of information needed to address the vital issues. The selection of panelists from the four basic institutional perspectives- government, industiy, academe, and citizens' groups (through nongovernmental organizations (NGOs))-ensured a high level of stakeholder representation on the panels. The already existing need for a water resource management information system has been magnified in the aftemnath of Hurricane Mitch. This information system would be beneficial for an early warning system in emergencies, and the modeling and simulation capabilities of the system would allow for advanced planning. Additionally, the outreach program will provide education to help Nicaraguan improve their water hygiene practices.

  6. From Waste Management to Resource Efficiency—The Need for Policy Mixes

    Directory of Open Access Journals (Sweden)

    Henning Wilts

    2016-07-01

    Full Text Available Treating waste as a resource and the design of a circular economy have been identified as key approaches for resource efficiency. Despite ambitious targets, policies and instruments that would enable a transition from a conventional waste management to an integrated and comprehensive resource management are still missing. Moreover, this will require innovative policy mixes which do not only address different end-of-pipe approaches but integrate various resource efficiency aspects from product design to patterns of production and consumption. Based on the results of a project funded by the Seventh Framework Programme for Research and Technological Development named “POLFREE—Policy Options for a resource efficient economy”, this paper addresses several aspects of the conceptualization of policy mixes with regard to waste as a specific resource efficiency challenge. The guiding research interest of this paper is the combination of policies necessary to create a full circular economy. In a first step, the present waste policy frameworks, institutions and existing incentives at national level are examined in order to disclose regulatory and policy gaps. Based on this, the second part of the paper describes and analyses specific waste-related resource efficiency instruments with regard to their potential impacts under the constraints of various barriers. Based on the assessment of the country analyses and the innovative instruments, the paper draws conclusions on waste policy mixes and political needs.

  7. Evaluating Programs That Promote Climate and Energy Education-Meeting Teacher Needs for Online Resources

    Lynds, S. E.; Buhr, S. M.

    2011-12-01

    The Climate Literacy and Energy Awareness Network (CLEAN) Pathway, is a National Science Digital Library (NSDL) Pathways project that was begun in 2010. The main goal of CLEAN is to generate a reviewed collection of educational resources that are aligned with the Essential Principles of Climate Science (EPCS). Another goal of the project is to support a community that will assist students, teachers, and citizens in climate literacy. A complementary program begun in 2010 is the ICEE (Inspiring Climate Education Excellence) program, which is developing online modules and courses designed around the climate literacy principles for use by teachers and other interested citizens. In these projects, we learn about teacher needs through a variety of evaluation mechanisms. The programs use evaluation to assist in the process of providing easy access to high quality climate and energy learning resources that meet classroom requirements. The internal evaluation of the CLEAN program is multidimensional. At the CLEAN resource review camps, teachers and scientists work together in small groups to assess the value of online resources for use in the classroom. The review camps are evaluated using observation and feedback surveys; the resulting evaluation reports provide information to managers to fine-tune future camps. In this way, a model for effective climate resource development meetings has been refined. Evaluation methods used in ICEE and CLEAN include teacher needs assessment surveys, teacher feedback at professional development opportunities, scientist feedback at resource review workshops, and regular analysis of online usage of resources, forums, and education modules. This paper will review the most successful strategies for evaluating the effectiveness of online climate and energy education resources and their use by educators and the general public.

  8. Equity in Distribution of Health Care Resources; Assessment of Need and Access, Using Three Practical Indicators.

    Directory of Open Access Journals (Sweden)

    Habib Omrani-Khoo

    2013-11-01

    Full Text Available Equitable distribution of health system resources has been a serious challenge for long ago among the health policy makers. Conducted studies have mostly ever had emphasis on equality rather than equity. In this paper we have attempted to examine both equality and equity in resources distribution.This is an applied and descriptive study in which we plotted Lorenz and concentration curves to describe graphically the distribution of hemodialysis beds and nephrologists as two complementary resources in health care in relation to hemodialysis patients. To end this, inequality and inequity were measured by calculating Gini- coefficient, concentration and Robin Hood indices. We used STATA and EXCEL software to calculate indicators.The results showed that inequality was not seen in hemodialysis beds in population level. However, distribution of nephrologists without considering population needs was accompanied with some sort of inequality. Gini- coefficient for beds and nephrologists distribution in population level was respectively 0.02 and 0.38. Hence, calculation of concentration index for distribution of hemodialysis beds and nephrologists with regard to population needs indicated that unlike beds distribution, equity gap between nephrologists distribution against patients distribution among the provinces was considerably significant again.Our results imply that although hemodialysis beds in Iran have been distributed in connection with the population need, nephrologists' distribution is not the same as hemodialysis beds one and this imbalance in complementary resources, can affect both efficiency and equitable access to services for population.

Results Of 209 cases, 166 (79%) were admitted to a medical ward and 43 (21%) to the intensive care unit (ICU). 61 (29%) cases were candidates for outpatient therapy per IDSA/ATS guidance with a CURB-65 score of 0 or 1 and absence of hypoxemia. 110 sputum cultures were ordered; however, an evaluable sample was obtained in 49 (45%) cases, median time from antibiotic initiation to specimen collection was 11 (IQR 6–19) hours, and a potential pathogen was identified in only 18 (16%). Blood cultures were routinely obtained for both non-ICU (81%) and ICU (95%) cases, but 15 of 36 (42%) positive cultures were false-positive results. The most common antibiotic regimen was ceftriaxone plus azithromycin (182, 87% cases). Discordant with IDSA/ATS recommendations, oral step-down therapy consisted of a new antibiotic class in 120 (66%), most commonly levofloxacin (101, 55%). Treatment durations were typically longer than suggested with a median of 10 (IQR 8 – 12) days. Conclusions In this cohort of patients hospitalized for CAP, management was frequently inconsistent with IDSA/ATS guideline recommendations revealing potential targets to reduce unnecessary antibiotic and health care resource utilization.

    2006-01-01

    Full Text Available Abstract Background Efforts to increase access to life-saving treatment, including antiretroviral therapy (ART, for people living with HIV/AIDS in resource-limited settings has been the growing focus of international efforts. One of the greatest challenges to scaling up will be the limited supply of adequately trained human resources for health, including doctors, nurses, pharmacists and other skilled providers. As national treatment programmes are planned, better estimates of human resource needs and improved approaches to assessing the impact of different staffing models are critically needed. However there have been few systematic assessments of staffing patterns in existing programmes or of the estimates being used in planning larger programmes. Methods We reviewed the published literature and selected plans and scaling-up proposals, interviewed experts and collected data on staffing patterns at existing treatment sites through a structured survey and site visits. Results We found a wide range of staffing patterns and patient-provider ratios in existing and planned treatment programmes. Many factors influenced health workforce needs, including task assignments, delivery models, other staff responsibilities and programme size. Overall, the number of health care workers required to provide ART to 1000 patients included 1–2 physicians, 2–7 nurses, Discussion These data are consistent with other estimates of human resource requirements for antiretroviral therapy, but highlight the considerable variability of current staffing models and the importance of a broad range of factors in determining personnel needs. Few outcome or cost data are currently available to assess the effectiveness and efficiency of different staffing models, and it will be important to develop improved methods for gathering this information as treatment programmes are scaled up.

    2010-12-01

    The province of Ontario, Canada, has a highly diverse and multicultural population. Specialty foods (i.e., foods from different cultures) are becoming increasingly available at retail food outlets and foods service establishments across the province; as a result, public health inspectors (PHIs) are increasingly required to assess the safety of foods with which they may be unfamiliar. The aim of this study was to investigate the concerns, perceptions, and self-identified needs of PHIs in Ontario with regard to specialty foods and food safety information resources in languages other than English. A cross-sectional online survey of 239 PHIs was conducted between April and June 2009. The study found that while some food safety information resources were available in languages other than English, fewer than 25% of respondents (56/239) were satisfied with the current availability of these resources. With regard to specialty foods, 60% of respondents (143/239) reported at least one specialty food with which they were not confident about their current food safety knowledge, and 64% of respondents (153/239) reported at least one specialty food with which they were dissatisfied with the current availability of food safety information. Therefore, the development of additional food safety information resources for specialty foods, and food safety resources in additional languages may provide enhanced support to PHIs involved in protecting and promoting a safe food supply.

    Canada has a plentiful resource base and a long history of innovation in bioenergy, biofuels and industrial biotechnology. Success of the industry depends on having the required human resources capacity such as the right number of skilled, job-ready professionals to support companies as they develop and commercialize new solutions. This document presented the results of a human resources survey conducted by BioTalent regarding the national and global bioenergy, biofuels and industrial biotechnology subsectors. It addressed a variety of issues, such as the increasing demand for bioenergy; the near-term perspective; growth factors; and the role of public policy. A subsector snapshot of human resources was also presented, with particular reference to the principal areas of need; types of roles required in the bio-economy; human resources capacity and company size; regional variances; skills gaps; reliance on outsourcing; knowledge, learning and connectedness; recruitment, retention and turnover; and the road ahead. Conclusions and recommendations were also offered. It was concluded that once the economy recovers, demand for bioenergy, biofuels and industrial products and services is expected to increase. 3 tabs., 6 figs.

    Full Text Available The market shows no signs of sustainable recovery after the crisis that hit the world economy in 2007, and therefore public intervention in the area of professional re-conversion is highly desirable. Public spending on training programs needs to be economically justified and closely monitored. We describe an econometric method to evaluate needed costs for training programs for professional skills development, based on a sample of pair values extracted from training projects implemented between 2008 and 2009. We find that, although the unitary value as resulted after applying the econometric model corresponds to the national available amount, by applying other types of indicators, such hour of training, can determine more efficient (less resources needed, cost-effective and effective (increased number of trained individuals for less costs values in what regards the process of delivering training programs.

    Four NASA Science Mission Directorate (SMD) Science Education and Public Outreach Forums organize individual SMD-funded E/PO projects and their teams into a coordinated effort. The Forums assist scientists and educators with becoming involved in SMD E/PO and make SMD E/PO resources and expertise accessible to the science and education communities. The Astrophysics Forum and the Astrophysics E/PO community have focused efforts to support and engage the higher education community on enhancing awareness of the resources available to them. To ensure Astrophysics higher education efforts are grounded in audience needs, we held informal conversations with instructors of introductory astronomy courses, convened sessions with higher education faculty and E/PO professionals at conferences, and examined existing literature and findings of the SMD Higher Education Working Group. This work indicates that most Astronomy 101 instructors are not specialists in areas of astrophysics where rapid progress is being made, older textbooks are out of date, and ideas are challenging for students. Instructors are seeking resources and training that support them in effectively teaching the latest science and are in need both basic material and information on new results. In this session, we will discuss our efforts to address these expressed needs, namely through Resource Guides and Slide Sets, and how these are applicable to topics in Heliophysics and Planetary Science. We have collaborated with the Astrophysics E/PO community, researchers, and Astronomy 101 instructors to create two Resource Guides on the topics of cosmology and exoplanets. These fields are ripe with scientific developments that college instructors have told us they find challenging to stay current. Each guide includes a wide variety of sources of background information, links to animations/simulations, classroom activities, and references on teaching each topic. Feedback from Astronomy 101 instructors indicated that the

    2014-07-01

    Full Text Available Katherine A Johansen Taber, Barry D Dickinson Department of Science and Biotechnology, American Medical Association, Chicago, IL, USA Background: The use of pharmacogenomic testing in the clinical setting has the potential to improve the safety and effectiveness of drug therapy, yet studies have revealed that physicians lack knowledge about the topic of pharmacogenomics, and are not prepared to implement it in the clinical setting. This study further explores the pharmacogenomic knowledge deficit and educational resource needs among physicians. Materials and methods: Surveys of primary care physicians, cardiologists, and psychiatrists were conducted. Results: Few physicians reported familiarity with the topic of pharmacogenomics, but more reported confidence in their knowledge about the influence of genetics on drug therapy. Only a small minority had undergone formal training in pharmacogenomics, and a majority reported being unsure what type of pharmacogenomic tests were appropriate to order for the clinical situation. Respondents indicated that an ideal pharmacogenomic educational resource should be electronic and include such components as how to interpret pharmacogenomic test results, recommendations for prescribing, population subgroups most likely to be affected, and contact information for laboratories offering pharmacogenomic testing. Conclusion: Physicians continue to demonstrate pharmacogenomic knowledge gaps, and are unsure about how to use pharmacogenomic testing in clinical practice. Educational resources that are clinically oriented and easily accessible are preferred by physicians, and may best support appropriate clinical implementation of pharmacogenomics.

  2. Evaluation of Human Resource Needs for a New Nuclear Power Plant: Armenian Case Study

    International Nuclear Information System (INIS)

    Rising expectations of an increased role for nuclear power in providing energy for future national and global sustainable development have become a reality in many Member States of the IAEA. Over the last several years, dozens of Member States have announced plans to embark on or expand nuclear power programmes. Reflecting on these developments, the IAEA has adjusted its priorities to focus more on the nuclear power programmes of newcomers. Specifically, the IAEA has produced publications providing guidance on the development of a national infrastructure for nuclear power (IAEA Nuclear Energy Series No. NG-G-3.1) and on managing human resources in the field of nuclear energy (IAEA Nuclear Energy Series No. NG-G-2.1). Additionally, assistance to eligible Member States through new technical cooperation (TC) projects has been increased, including direct support through on-site assist visits. In 2007-2008, the IAEA carried out a TC project titled 'Feasibility study of nuclear energy development in Armenia: Evaluation of human resource needs in conjunction with new NPP build' (ARM-005). The project analysed the human resource demands required to support work at all stages of the life cycle of a new power unit planned for Armenia. This included drafting proposals for the means, conditions and requirements for development of human resource capabilities needed to carry out the work. This report is intended to complement the previous IAEA publications by providing an in-depth technical consideration into this critical area of human resource development. The report summarizes major findings of the TC project and details the tasks linked to management of the human resources that will be required by a country planning to build a new NPP. Additional guidance on the development of a national nuclear infrastructure can be found in the IAEA publication 'Milestones in the Development of a National Infrastructure for Nuclear Power', IAEA Nuclear Energy Series No. NG-G-3.1.

  4. The future of antibiotics.

    Spellberg, Brad

    2014-01-01

    Antibiotic resistance continues to spread even as society is experiencing a market failure of new antibiotic research and development (R&D). Scientific, economic, and regulatory barriers all contribute to the antibiotic market failure. Scientific solutions to rekindle R&D include finding new screening strategies to identify novel antibiotic scaffolds and transforming the way we think about treating infections, such that the goal is to disarm the pathogen without killing it or modulate the host response to the organism without targeting the organism for destruction. Future economic strategies are likely to focus on 'push' incentives offered by public-private partnerships as well as increasing pricing by focusing development on areas of high unmet need. Such strategies can also help protect new antibiotics from overuse after marketing. Regulatory reform is needed to re-establish feasible and meaningful traditional antibiotic pathways, to create novel limited-use pathways that focus on highly resistant infections, and to harmonize regulatory standards across nations. We need new antibiotics with which to treat our patients. But we also need to protect those new antibiotics from misuse when they become available. If we want to break the cycle of resistance and change the current landscape, disruptive approaches that challenge long-standing dogma will be needed. PMID:25043962

    Full Text Available The present study is based on Kaplan and Kaplan’s (1989 theory explaining the restorative effects that nature has on a person’s psychic. According to this theory, nature exerts a “soft fascination” combining the activation of involuntary attention mechanisms with the reflexive awareness, allowing a spontaneous detachment from stress factors and automatic functioning, and also the feeling of compatibility between personal purposes, and the possibilities for action offered by the environment (a sense of meaning. Our objective was to investigate the effects of nature on Self awareness: the immediate, emotional experience; needs awareness and organization; plans for action, and availability of resources, both personal, and external. We conducted an experiment with an experimental group (persons watching a video with life in nature and an active control group (involved in a psychotherapeutic technique focused on confronting and solving personal difficulties by creative means, accompanied by a short psychological analysis. The effects were assessed in terms of “here and now” emotions and available resources according to a self-evaluation scale, and with open-ended questions regarding personal needs and goals. The results showed that, for the experimental group, the relaxation effects and the awareness of long term goals were stronger, while all the other effects were the same as for the control group. The results suggest that indeed, nature helps a person get in contact with her profound Self, allowing the access to both “here and now” basic needs, and also long term goals (inner sources of meaning, the sense of connection between internal tendencies, personal, and external resources, resulting in increased positive emotions, and decreased negative emotions. Nature contemplation may facilitate a meditative state whit all its positive effects.

    Full Text Available Abstract Background Concerns have been expressed regarding the adequacy of ethics review systems in developing countries. Limited data are available regarding the structural and functional status of Research Ethics Committees (RECs in the Middle East. The purpose of this study was to survey the existing RECs in Egypt to better understand their functioning status, perceived resource needs, and challenges. Methods We distributed a self-administered survey tool to Egyptian RECs to collect information on the following domains: general characteristics of the REC, membership composition, ethics training, workload, process of ethics review, perceived challenges to effective functioning, and financial and material resources. We used basic descriptive statistics to evaluate the quantitative data. Results We obtained responses from 67% (12/18 of the identified RECs. Most RECs (10/12 have standard operating procedures and many (7/12 have established policies to manage conflicts of interests. The average membership was 10.3 with a range from 7-19. The predominant member type was physicians (69.5% of all of the REC members with little lay representation (13.7%. Most RECs met at least once/month and the average number of protocols reviewed per meeting was 3.8 with a range from 1-10. Almost three-quarters of the members from all of the 12 RECs indicated they received some formal training in ethics. Regarding resources, roughly half of the RECs have dedicated capital equipment (e.g., meeting room, computers, office furniture, etc; none of the RECs have a formal operating budget. Perceived challenges included the absence of national research ethics guidelines and national standards for RECs and lack of ongoing training of its members in research ethics. Conclusion Our study documents several areas of strengths and areas for improvements in the operations of Egyptian RECs. Regarding strengths, many of the existing RECs meet frequently, have a majority of members

    The need to use front-line antibiotics wisely has never been greater. Antibiotic resistance and multi-drug resistant infection, driven by antibiotic use, remain major public health and professional concerns. To overcome these infection problems, use of older antibiotics active against multi drug-resistant pathogens is increasing - for example, colistin, fosfomycin, pivmecillinam, pristinamycin, temocillin and oral tetracyclines. The number of new antibacterials reaching clinical practice has reduced significantly in the last 20 years, most being focused on therapy of Gram-positive infection - eg linezolid, daptomycin, telavancin and ceftaroline. Recent guidance on antibiotic stewardship in NHS trusts in England is likely to provide a backdrop to antibiotic use in hospitals in the next 5 years. PMID:23760700

Four in-depth case studies are used to explore the tensions inherent in providing coherent and user-oriented resources to legal self-helpers in environments where service providers attempt to convey complex legal information, knowledge and skills to people at the point of legal exigency. The needs of the consumer for basic process oriented and solutions focused resources do not always coincide with the objectives of providers to impart sufficient legal knowledge, information and skills to allow the consumer to work through those processes as an informed citizen. Cet article porte sur l’utilité des ressources conçues pour aider les gens à effectuer eux-mêmes le travail juridique qu’ils requièrent. Quatre études de cas approfondies servent à examiner les tensions inhérentes à la distribution de ressources d’auto-assistance juridique cohérentes axées sur l’utilisateur dans des milieux où les fournisseurs de services cherchent à transmettre des connaissances, de l’information et des compétences juridiques complexes, selon les exigences de la loi. La nécessité pour le client d’obtenir des ressources axées sur les solutions et les procédures de base ne va pas toujours dans le sens de l’objectif des fournisseurs de services, qui consiste à lui transmettre des connaissances, de l’information et des compétences juridiques suffisantes pour qu’il puisse mener à bien ces procédures en tant que citoyen informé.

  16. The Soil Degradation Paradox: Compromising Our Resources When We Need Them the Most

    Directory of Open Access Journals (Sweden)

    Catherine DeLong

    2015-01-01

    Full Text Available Soil degradation can take many forms, from erosion to salinization to the overall depletion of organic matter. The expression of soil degradation is broad, and so too are the causes. As the world population nears eight billion, and the environmental uncertainty of climate change becomes more manifest, the importance of our soil resources will only increase. The goal of this paper is to synthesize the catalysts of soil degradation and to highlight the interconnected nature of the social and economic causes of soil degradation. An expected three billion people will enter the middle class in the next 20 years; this will lead to an increased demand for meat, dairy products, and consequently grain. As populations rise so do the economic incentives to convert farmland to other purposes. With the intensity and frequency of droughts and flooding increasing, consumer confidence and the ability of crops to reach yield goals are also threatened. In a time of uncertainty, conservation measures are often the first to be sacrificed. In short, we are compromising our soil resources when we need them the most.

  17. Generating human resources in nuclear engineering in India: need of the hour

    International Nuclear Information System (INIS)

    With the fast growth of energy requirement scenario, particularly, in India with limited dependence on fossil power and increased emphasis on green power we have lots of nuclear power plant and associated projects in pipeline. This requires enormous human resources trained and qualified in nuclear engineering who will be engaged in all aspects of nuclear plant projects right from conceptualization, design, construction, development, operation, maintenance till decommissioning. As on today, Department of Atomic Energy (DAE) in Government of India is almost the only agency catering to this need. DAE grooms graduate engineers from various disciplines and postgraduates from sciences, specially, Physics and Chemistry. But, it takes enough financial resources and full 1-year duration past graduation from Indian Government. Even after imparting training to these freshly recruited DAE employees, sizeable chunk of the population quit DAE for better prospect such as higher studies abroad, management studies, IT profession etc. Also, the people trained in nuclear engineering are fewer in number than required and the gap would be increasingly large as time progresses and increasing number of nuclear plants would be constructed/operational. Comparatively larger number of engineering graduates currently produced in India are in Computer Engineering/Information Technology rather than in conventional disciplines like Civil, Mechanical, Electrical, Electronics and Telecommunications Engineering. This poses another problem of orienting/motivating the manpower in nuclear fields. Considering these problems the author proposes to produce and develop nuclear engineering graduates directly in the academic institutions which will help the nation in reducing the gap between the increasing demand of manpower in view of large number of nuclear plants in the pipeline and the availability of the nuclear engineers. Even large number of industries related to manufacturing and consultancy also

BATAN's strategic planning is described in four areas, those are: 1. Basic human needs, 2. Energy, natural resources and environment, 3. Industry, 4. Socio-cultural and institution. Priority has been given to fulfill, as well as to promote agriculture, health and the industry related to people's welfare, which may develop and improve the immediate needs of the people. In the meantime, we have made considerable investments in manpower development in anticipation of the introduction of nuclear power. BATAN, as of September 1999, has 3889 employees, 26 % of them have bachelor degree, 6 % hold master degrees, and only 2% hold doctoral degree, a total of 34 % employees with university education. Others 11 % have either non-vocational or vocational education beyond High School. The rest of 55 % have high school education or lower, they are administrative clerks (25 %) or technicians (30 %). In the human resources development, BATAN's Education and Training Center, in collaboration with some universities and other national/international institutions, is managing education and training programs for employees. To date, there are 43 BATAN employees studying in various universities in Japan, while another 42 employees are studying in six different countries. Research and Development that have more direct impact to the community will become a priority in the coming years. Without undermining the importance of basic research in advanced fields, we will expect to have more research on application to optimize utilization of research reactors and related facilities for the benefit of both the energy and non-energy sectors.

    As science educators based in institutional outreach programs, we work with many scientists on education and outreach projects involving teachers, students, and the public. While our scientist colleagues bring varied disciplinary interests, educational expertise, and communication skills to their education work, one strength that all scientists bring to these collaborations is their profound knowledge of the inquiry process. We have begun to develop a program of professional development for scientists that focuses on scientific inquiry in the classroom. Inquiry is the appropriate topic of focus for an initial professional development experience for scientists, because it is a crucial and broadly applicable part of national science education goals, and because all scientists understand it in a deep and personal way. As articulated in the National Science Education Standards, inquiry is both a recommended strategy for learning and teaching scientific concepts, and a content area in its own right, with the aim that students understand the process of science and can conduct scientific investigations. We will describe our multi-faceted program, which includes professional development workshops, development and sharing of resources, and a research-with-evaluation study to examine the readiness, response, and needs of the scientific community for professional development to further its education work. We will discuss ways in which scientists can apply their understanding of inquiry to their education work as well as identify other needs that must also be addressed. While inquiry is not the only thing that "busy scientists need to know," it is a good topic for starting fruitful conversations among scientists, K-12 educators, and those who bridge these communities.

    Full Text Available BACKGROUND: In order to achieve Millennium Development Goals 4, 5 and 6, it is essential to address adolescents' health. OBJECTIVE: To estimate the additional resources required to scale up adolescent friendly health service interventions with the objective to reduce mortality and morbidity among individuals aged 10 to 19 years in 74 low- and middle- income countries. METHODS: A costing model was developed to estimate the financial resources needed to scale-up delivery of a set of interventions including contraception, maternity care, management of sexually transmitted infections, HIV testing and counseling, safe abortion services, HIV harm reduction, HIV care and treatment and care of injuries due to intimate partner physical and sexual violence. Financial costs were estimated for each intervention, country and year using a bottom-up ingredients approach, defining costs at different levels of delivery (i.e., community, health centre, and hospital level. Programme activity costs to improve quality of care were also estimated, including activities undertaken at national-, district- and facility level in order to improve adolescents' use of health services (i.e., to render health services adolescent friendly. RESULTS: Costs of achieving universal coverage are estimated at an additional US$ 15.41 billion for the period 2011-2015, increasing from US$ 1.86 billion in 2011 to US$ 4,31 billion in 2015. This corresponds to approximately US$ 1.02 per adolescent in 2011, increasing to 4.70 in 2015. On average, for all 74 countries, an annual additional expenditure per capita ranging from of US$ 0.38 in 2011 to US$ 0.82 in 2015, would be required to support the scale-up of key adolescent friendly health services. CONCLUSION: The estimated costs show a substantial investment gap and are indicative of the additional investments required to scale up health service delivery to adolescents towards universal coverage by 2015.

    Surgeons continually struggle to reduce orthopaedic infections, but no current treatment offers minimum side effects with maximum effectiveness. Antibiotics mixed in plaster of paris have been successful in treating large bony defects in patients with chronic osteomyelitis, and have the advantage of being well tolerated and absorbed by the body. Antibiotics impregnated in polymethylmethacrylate (PMMA) have offered local antibiotic delivery with some success. However, the effect of the antibiotic on the bone cement, the inconsistent elution of the antibiotic, and the need to remove the PMMA implant drives the need for a better system of antibiotic delivery. Polymers or copolymers of antibiotic-impregnated polylactic acid, polyglycolic acid or polyparadioxanone may provide an absorbable system for localized antibiotic delivery. Similar biodegradable systems used to treat small bone fractures have been successful with minimal side effects. In vitro studies have shown promising results of antibiotic elution from bioabsorbable microspheres and beads. Animal in vivo tests have shown that antibiotic impregnated polymers can successfully treat induced osteomyelitis in rabbits and dogs. These studies have provided consistent reproducible results, and now it is time to plan human trials to assess the efficacy of antibiotic microspheres implanted in infected bone and to plan in vivo and in vitro animal testing to investigate the feasibility of antibiotic-polymer-coated components.

  6. Present status and needs of human resource development in nuclear field in Korea

    International Nuclear Information System (INIS)

    The Nuclear Training Center (NTC) of KAERI (Korea Atomic Energy Research Institute) began training technical personnel in the field of radioisotope utilization and radiation protection during the 1960's. During the first stage of the nation's nuclear power project in the 1970's, the main effort of the Center focused on training those in nuclear power and nuclear engineering. During a stage of increased technical self-reliance in the 1980's, the Center extended its training role to implement more specific training courses on nuclear power and safety fields. Since 1983, the Center has been empowered at the request of government to provide retraining courses for nuclear-related license holders and qualified engineers. The Center has offered IAEA regional training course annually for Asia and Pacific region member states since 1988. Since 1967, the total number of trainees is up to 27,777 as of the end of 1998. KEPCO (Korea Electric Power Corporation) started Nuclear Power Education Center (NPEC) in 1990. The outlines of KEPCO's in-house training programs are presented in the report. The reactor operators, and the persons engaged in nuclear fuel materials, radioisotope or radiation generating devices need particular licenses in accordance with Korean Atomic Energy Laws and Regulation. NTC/KAERI and NPEC/KEPCO should report annual retraining programs for licensed personnel to Ministry Of Science and Technology (MOST) every year. The outlines of projects, which are directly related to human resources development in nuclear field in Korea, are described in the paper. The International Atomic Energy Agency (IAEA) has made efforts to provide training programs for technical personnel of developing countries for the peaceful uses of nuclear energy. Korea has also received lots of assistance for her manpower development from the Agency. Korea is now on the verge of transforming herself from a technology recipient country in some practical and fundamental fields. The

    The first nuclear power plant was nearing completion. However, due to change in political climate and support for the nuclear power program, this has been mothballed. There is a possibility for the introduction of nuclear power plant in the country's projected energy sources by the year 2020. The country has one research reactor, but at the present time it is undergoing repair and is not operational. The Philippine Nuclear Research Institute (PNRI), an Institute under the Department of Science and Technology (DOST), is the sole government agency mandated by the law to take charge of all matters pertaining to nuclear science and technology, and the regulation of nuclear energy. There is one another government agency, the Radiation Health Service (RHS) of the Department of Health, which is responsible for regulating the use and application of X-rays and non-ionizing radiation. The PNRI conducts national training courses in nuclear science and technology, and radiation protection to users of radioisotopes. Individual courses are outlined in the paper. Up to the present time, around 7,300 have participated in national training courses conducted by PNRI. Distributions of PNRI trainees are: 53 % for industrial, 12 % medical, 12 % for academe, and 23 % for others. Nuclear science and technology education in schools and universities are presented.

    Despite advances in treatment, head and neck cancer (HNC) patients often experience considerable functional impairment during and following treatment. As a result, family caregivers are essential in a patient's recovery; however, few caregivers are well-prepared to handle the extensive caregiving needs of this patient population. To date, little is known about HNC caregivers' informational needs in this role. Thus, we surveyed a sample of HNC caregivers about their informational needs including those related to interacting in the medical context as a caregiver and meeting patient needs. We also asked these caregivers their preferences for obtaining caregiving information. We conducted a cross-sectional study of 59 family caregivers for HNC patients who had completed radiation therapy at a comprehensive cancer center. The majority of caregivers (74.6%) reported having high informational need at diagnosis related to interacting as a caregiver. Although the need for such information decreased over time, over half still had a high need for information at treatment end. Importantly, caregivers who desired information about reducing patient pain and distress also reported having greater informational needs on issues related to interacting in the medical context. Further, the caregivers most often preferred to receive information from health-care professionals as a first source. However, preferring an informal (e.g., Internet) resource at first was significantly associated with needing information on how to talk to a doctor or nurse. The development of evidence-based resources and tools for HNC caregivers as well as clinicians may help caregivers more effectively manage patient symptoms and warrants further attention. Further, Internet resources may represent an effective resource for providing caregivers with strategies toward enhancing communication with healthcare professionals. PMID:25893922

  10. Enhanced Geothermal Systems (EGS) R&D Program: US Geothermal Resources Review and Needs Assessment

    Energy Technology Data Exchange (ETDEWEB)

    2000-11-30

    The purpose of this report is to lay the groundwork for an emerging process to assess U.S. geothermal resources that might be suitable for development as Enhanced Geothermal Systems (EGS). Interviews of leading geothermists indicate that doing that will be intertwined with updating assessments of U.S. higher-quality hydrothermal resources and reviewing methods for discovering ''hidden'' hydrothermal and EGS resources. The report reviews the history and status of assessment of high-temperature geothermal resources in the United States. Hydrothermal, Enhanced, and Hot Dry Rock resources are addressed. Geopressured geothermal resources are not. There are three main uses of geothermal resource assessments: (1) They inform industry and other interest parties of reasonable estimates of the amounts and likely locations of known and prospective geothermal resources. This provides a basis for private-sector decisions whether or not to enter the geothermal energy business at all, and for where to look for useful resources. (2) They inform government agencies (Federal, State, local) of the same kinds of information. This can inform strategic decisions, such as whether to continue to invest in creating and stimulating a geothermal industry--e.g., through research or financial incentives. And it informs certain agencies, e.g., Department of Interior, about what kinds of tactical operations might be required to support such activities as exploration and leasing. (3) They help the experts who are performing the assessment(s) to clarify their procedures and data, and in turn, provide the other two kinds of users with a more accurate interpretation of what the resulting estimates mean. The process of conducting this assessment brings a spotlight to bear on what has been accomplished in the domain of detecting and understanding reservoirs, in the period since the last major assessment was conducted.

    Full Text Available Antibiotics are commonly used in dentistry for prophylactic as well as for therapeutic purposes. Most often antibiotics are used in unwarranted situations, which may give rise to resistant bacterial strains. Dentists want to make their patients well and to prevent unpleasant complications. These desires, coupled with the belief that many oral problems are infectious, stimulate the prescribing of antibiotics. Good knowledge about the indications of antibiotics is the need of the hour in prescribing antibiotics for dental conditions.

  13. Preparing for the future: Higher education meeting environmental restoration and waste management human resource needs

    International Nuclear Information System (INIS)

    The Office of Environmental Restoration and Waste Management (ER/WM) of the U.S. Department of Energy (DOE) has as its goal the elimination of risks from hazardous waste to human health and safety and the environment or the reduction of these risks to prescribed safe levels. The achievement of this goal requires the availability of sufficient and appropriately educated scientists, engineers, and technicians. A preliminary workforce needs assessment conducted for the Office of Environmental Restoration and Waste Management in 1990 indicated that the technical workforce involved in ER/WM activities would grow by 50 to 70 percent by 1995. A more exhaustive assessment is currently underway. To ensure the availability of the necessary human resources, the Office has initiated a series of education programs. The programs designed for the college/university levels are expected to increase the number of students pursuing associate, baccalaureate, and advanced degrees in ER/WM relevant science and engineering disciplines and to initiate research and training in technical areas supportive of the ER/WM mission. The ER/WM Scholarship program provides scholarships to undergraduate students pursuing science and engineering degrees at designated two- and four-year academic institutions. Fifty-four four-year and six two-year institutions are involved. The ER/WM Fellowship program supports graduate study and research at designated academic institutions in specified science and engineering disciplines or in interdisciplinary programs, Thirty graduate students are pursuing advanced degrees in disciplines supportive of the ER/WM mission at 14 different academic institutions. Scholars and fellows are required to spend one summer at a DOE facility participating in ongoing ER/WM projects. The fellowship and scholarship programs are expected to create a pool of appropriately educated professionals ready to enter the workforce and contribute to the DOE mission. To ensure the full

    Antibiotic stewardship is becoming a requirement for nursing homes. Programs should be interdisciplinary and multifaceted; should have support from nursing home administrators; and should aim to promote antibiotics only when needed, not just in case. Recommended components include use of evidence-based guidelines; ongoing monitoring of antibiotic prescriptions, cultures, and study results; monitoring of health outcomes; use of nursing home-specific antibiograms; regular reporting and feedback to medical providers and nurses; and education of residents and families.

  2. Poverty in the midst of plenty: unmet needs and distribution of health care resources in South Korea.

    Directory of Open Access Journals (Sweden)

    Jongho Heo

    Full Text Available BACKGROUND: The unmet needs for health care have been used as an alternative measurement to monitor equity in health services. We sought to examine contextual influences on unmet needs for health care whereas precedent studies have been focused on individual characteristics on them. METHODS AND FINDINGS: The current study conducted multilevel logistic regression analysis to assess the effects of individual- and contextual-level predictors in meeting individual health care needs in South Korea. We sampled 7,200 individuals over the age of 19 in the Fourth Korea National Health and Nutrition Examination Survey in 2009. Included in the regression model were individual predictors such as demographic variables, socio-economic status, and self-rated health; the density of beds and physicians in public and private sectors within different regions were used as contextual-level predictors. This study showed the inverse association between unmet needs and regional resources in private sectors after controlling for the effects of individual-level predictors. CONCLUSION: Our findings suggest that increasing regional resources in private sectors might produce inefficiency in the health care system and inequity in access to health services, particularly where the competition in private health care sectors was highly stimulated under the fee-for-service reimbursement scheme. Policies for the reallocation of health care resources and for reduction of individual health care costs are needed in Korea.

    Landscape Conservation Cooperatives (LCCs) are a network of 22 public-private partnerships, defined by ecoregion, that share and provide science to ensure the sustainability of land, water, wildlife and cultural resources in North America. LLCs were established by the U.S. Department of Interior (DOI) in recognition that response to climate change must be coordinated on a landscape-level basis because important resources, ecosystem processes and resource management challenges extend beyond national wildlife refuges, Bureau of Land Management lands, national parks, and even international boundaries. Therefore, DOI agencies must work with other Federal, State, Tribal (U.S. indigenous peoples), First Nation (Canadian indigenous peoples), and local governments, as well as private landowners, to develop landscape-level strategies for understanding and responding to climate change.

    Duncan, Mary Katherine Waibel; Blugis, Ann

    2011-08-01

    As hospitality houses welcome greater numbers of families and families requiring longer stays, they do so in the absence of a widely accepted theory to guide their understanding of guests' needs and evaluations of how well they meet those needs. We propose A. Maslow's (1970) Hierarchy of Needs as a conceptual framework for understanding what makes a hospitality house a home for families of pediatric patients and for guiding the activities of hospitality houses' boards of directors, staff, volunteers, and donors. This article presents findings from a theory-driven evaluation of one hospitality house's ability to meet guests' needs, describes the house's best practice standards for addressing guests' needs, and suggests areas for future research.

    Science.gov (United States)

    Brand, H; Menke, R

    1997-07-01

    The RAWP formula used for resource allocation in Great Britain between 1976 and 1991 is a morbidity-oriented instrument of controlling, which has so far received only little attention in Germany. The development of this model was supported by the intention to intervene in the regional pattern of hospital supply by means of resource allocation and to refine it according to the guiding principles of equity and efficiency. The basic elements-regional population, average bed use, ICD chapter-specific SMRs-are discussed and the various modifications outlined. The RAWP formula's potentials of controlling resulted in a progressive reduction of the apparent disparities between regions in hospital supply, and knee was considered to be a "qualified success". The future development in the sense of an internal market addressed. PMID:9333384

    Full Text Available Improving the quality of English language teacher education (ELTE programs has become a major point of consideration; however, such programmatic evaluations are markedly rare. This study utilizes both numeric and interpretive qualitative data in a blended research design. The study addresses, vis-à-vis current research in related fields: What is the current situation of the Turkish ELTE programs in terms of curriculum strength and faculty resources? How do the program directors and teacher candidates envision the situation of their programs in terms of curriculum strength and faculty resources? Data included 45 ELTE curricula, interviews with 24 program directors and pre-service teachers, documents, and test scores. Findings revealed several significant associations between school type (public/private and rank (low/high and the number of faculty with expertise in critical areas in the field. Qualitative critical evaluations suggest both perceptual matches and mismatches between program directors and teacher candidates regarding programmatic strengths and weaknesses.

  18. Budgeting based on need: a model to determine sub-national allocation of resources for health services in Indonesia

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available Abstract Background Allocating national resources to regions based on need is a key policy issue in most health systems. Many systems utilise proxy measures of need as the basis for allocation formulae. Increasingly these are underpinned by complex statistical methods to separate need from supplier induced utilisation. Assessment of need is then used to allocate existing global budgets to geographic areas. Many low and middle income countries are beginning to use formula methods for funding however these attempts are often hampered by a lack of information on utilisation, relative needs and whether the budgets allocated bear any relationship to cost. An alternative is to develop bottom-up estimates of the cost of providing for local need. This method is viable where public funding is focused on a relatively small number of targeted services. We describe a bottom-up approach to developing a formula for the allocation of resources. The method is illustrated in the context of the state minimum service package mandated to be provided by the Indonesian public health system. Methods A standardised costing methodology was developed that is sensitive to the main expected drivers of local cost variation including demographic structure, epidemiology and location. Essential package costing is often undertaken at a country level. It is less usual to utilise the methods across different parts of a country in a way that takes account of variation in population needs and location. Costing was based on best clinical practice in Indonesia and province specific data on distribution and costs of facilities. The resulting model was used to estimate essential package costs in a representative district in each province of the country. Findings Substantial differences in the costs of providing basic services ranging from USD 15 in urban Yogyakarta to USD 48 in sparsely populated North Maluku. These costs are driven largely by the structure of the population

  1. Methodology in improving antibiotic implementation policies.

    Science.gov (United States)

    Özgenç, Onur

    2016-06-26

    The basic requirements of antibiotic prescribing are components of methodology; knowledge, logical reasoning, and analysis. Antimicrobial drugs are valuable but limited resources, different from other drugs and they are among the most commonly prescribed drugs all over the world. They are the only drugs which do not intentionally affect the patient. They affect the pathogens which invade the host. The emergence and spread of antibiotic-resistant pathogens are accelerated by heavy antibiotic usage. The effective antimicrobial stewardship and infection control program have been shown to limit the emergence of antimicrobial-resistant bacteria. In this respect, education for antibiotic prescribing could be designed by going through the steps of scientific methodology. A defined leadership and a coordinated multidisciplinary approach are necessary for optimizing the indication, selection, dosing, route of administration, and duration of antimicrobial therapy. In scenarios, knowledge is also as important as experience for critical decision making as is designated. In this setting, the prevalence and resistance mechanisms of antimicrobials, and their interactions with other drugs need to be observed. In this respect, infectious disease service should play an important role in improving antimicrobial use by giving advice on the appropriate use of antimicrobial agents, and implementing evidence-based guidelines.

    Directory of Open Access Journals (Sweden)

    2012-05-01

    Full Text Available Understanding the genetic resource status of an economic crop such as Cola is a very relevant prerequisite for its improvement and advancing its research attention. This will, no doubt, also improve the adoption of these grossly under-utilized species of West African origin. Sterility, self and cross incompatibilities, unpleasantly tall trees and low nut yield are among the problems faced by growers of this crop. As the crop takes up to seven years to produce its first fruit, while some trees may not bear fruit within the first fifteen years of field establishment or even throughout life, many farmers have adopted other crops as their source of livelihood. This poses a great threat to the livelihood of the rural populace whose main occupation revolves around kola trading. Hand-pollinated experiments showed a yield of 3,000-10,000 nuts per tree per year, as against 250 nuts per tree per year usually obtained in open-pollinated plants. In Nigeria, recent efforts in Cola breeding and improvement include plant introduction, progeny trials, hybrid trials, clonal trials, root stock-scion compatibility trials and variability studies resulting in further plant selections. The highest diversity of Cola spp. has been observed in Nigeria ’s boundary with Cameroon. This review is intended to beam the searchlight on Cola breeding in Nigeria and the availability of genetic diversity that can be assembled and utilized for the improvement of this all-important tree crop.

    The need-based approach (assuming that higher consumption of tree products would motivate farmers to adopt agroforestry) has led to uneven success, in many cases failure, of many agroforestry projects. Current study investigated the association between fuelwood and forest resource use, and agroforestry adoption based on a survey of 401 households in the Indian Western Himalaya. Data on household domestic fuel utilisation and forest resource use were collected using a questionnaire in personal interviews. Agroforestry adoption increased significantly with increase in distance of nearest State forest from the house, distance travelled to collect fuelwood, and consumption of cattle dung, crop residues, charcoal, kerosene and liquid petroleum gas as domestic fuels by the household. Agroforestry adoption was also significantly higher in households with non-forest than those with State forests as primary source of fuelwood and timber. The proportion of adopters decreased significantly with increase in quantity of fuelwood used for domestic consumption, frequency of collection from State forests, total domestic energy consumption, fuelwood dependency, timber consumption and availability of timber through rights of households on State forests. Logistic regression analysis revealed that none of the factors related to need (quantity of fuelwood and timber used) appeared in the model but primary source of fuelwood, distance travelled to collect fuelwood and availability of timber through rights on the State forests appeared as important factors. This implies that need of the tree products is not a necessary condition to motivate farmers to adopt agroforestry, rather, it is accessibility of tree products which influence agroforestry adoption.

    Probiotics are live microorganisms, mainly belonging to the genera Lactobacillus and Bifidobacterium, although also strain of other species are commercialized, that have a beneficial effect on the host. From the perspective of antibiotic use, probiotics have been observed to reduce the risk of certain infectious disease such as certain types of diarrhea and respiratory tract infection. This may be accompanied with a reduced need of antibiotics for secondary infections. Antibiotics tend to be effective against most common diseases, but increasingly resistance is being observed among pathogens. Probiotics are specifically selected to not contribute to the spread of antibiotic resistance and not carry transferable antibiotic resistance. Concomitant use of probiotics with antibiotics has been observed to reduce the incidence, duration and/or severity of antibiotic-associated diarrhea. This contributes to better adherence to the antibiotic prescription and thereby reduces the evolution of resistance. To what extent probiotics directly reduce the spread of antibiotic resistance is still much under investigation; but maintaining a balanced microbiota during antibiotic use may certainly provide opportunities for reducing the spread of resistances. Key messages Probiotics may reduce the risk for certain infectious diseases and thereby reduce the need for antibiotics. Probiotics may reduce the risk for antibiotic-associated diarrhea Probiotics do not contribute to the spread of antibiotic resistance and may even reduce it. PMID:27092975

    The purpose of this study was to evaluate the surgical effort of total knee arthroplasty (TKA) for posttraumatic osteoarthritis (PTOA) compared with primary osteoarthritis (OA). A total of 1841 TKAs were analyzed, including 170 patients with PTOA, that resulted from soft tissue trauma in 83 patients and fractures in 87 patients. Results showed that patients were significantly younger at the time of surgery in the posttraumatic group (62 vs 71 years; P<.001). Furthermore, fracture was associated with 3.7 years earlier need of TKA compared with soft tissue trauma. Operation time was significantly longer for both of the posttraumatic groups compared with OA (P<.001). Patients undergoing TKA after knee injuries are younger and surgical treatment is more challenging compared with TKA for OA. Extended operation time and implant systems with higher constraint and modular options are required. [Orthopedics. 2016; 39(3):S36-S40.]. PMID:27219725

    2013-12-01

    The North Slope Science Initiative (NSSI) is an intergovernmental science collaboration forum in Arctic Alaska (USA). NSSI has initiated a 'Scenario Planning' effort with the focal question: 'What is the future of energy development, resource extraction, and associated support activities on the North Slope and adjacent seas through 2040?' With over 500 thousand square kilometers of land and sea, the area of the North Slope and adjacent seas is believed to have some of the largest oil, gas, and coal potential remaining in the United States, but it is also home to a diverse array of fish, wildlife, and plant resources that support a vibrant subsistence culture. Our scenario planning will involve a full and collaborative dialogue among a wide range of U.S. Arctic stakeholders, including Alaska Native subsistence users, local communities, academia, non-governmental organizations, and a variety of industries (oil and gas, mining, transportation, etc.) and government agencies (federal, state, local). The formulation of development scenarios and an understanding of their implications will provide a practical context for NSSI member agencies to make informed decisions about the research and monitoring that will be needed to sustain these resources and to plan for safe energy and resource development in the face of impending changes. The future of Arctic America is difficult to accurately predict, particularly in an era of intense pressures from both energy development and climate warming. However, it will almost surely be characterized by highly consequential and unprecedented changes. Complex and uncertain are appropriate descriptors of the Arctic and its future; and scenario planning has proven an effective tool to help engage diverse stakeholders in a focused dialogue and systematic thinking about plausible futures in complex and uncertain settings. The NSSI leadership recognized the critical need for this dialogue and has begun a scenario planning effort for the North

  1. Nanoinformatics workshop report: current resources, community needs and the proposal of a collaborative framework for data sharing and information integration

    International Nuclear Information System (INIS)

    The quantity of information on nanomaterial properties and behavior continues to grow rapidly. Without a concerted effort to collect, organize and mine disparate information coming out of current research efforts, the value and effective use of this information will be limited at best. Data will not be translated to knowledge. At worst, erroneous conclusions will be drawn and future research may be misdirected. Nanoinformatics can be a powerful approach to enhance the value of global information in nanoscience and nanotechnology. Much progress has been made through grassroots efforts in nanoinformatics resulting in a multitude of resources and tools for nanoscience researchers. In 2012, the nanoinformatics community believed it was important to critically evaluate and refine currently available nanoinformatics approaches in order to best inform the science and support the future of predictive nanotechnology. The Greener Nano 2012: Nanoinformatics Tools and Resources Workshop brought together informatics groups with materials scientists active in nanoscience research to evaluate and reflect on the tools and resources that have recently emerged in support of predictive nanotechnology. The workshop goals were to establish a better understanding of current nanoinformatics approaches and to clearly define immediate and projected informatics infrastructure needs of the nanotechnology community. The theme of nanotechnology environmental health and safety (nanoEHS) was used to provide real-world, concrete examples on how informatics can be utilized to advance our knowledge and guide nanoscience. The benefit here is that the same properties that impact the performance of products could also be the properties that inform EHS. From a decision management standpoint, the dual use of such data should be considered a priority. Key outcomes include a proposed collaborative framework for data collection, data sharing and information integration. (paper)

    Systemic antibiotics in conjunction with scaling and root planing (SRP), can offer an additional benefit over SRP alone in the treatment of periodontitis, in terms of clinical attachment loss (CAL) and pocket depth change, and reduced risk of additional CAL loss. However, antibiotics are not innocuous drugs. Their use should be justified on the basis of a clearly established need and should not be substituted for adequate local treatment. The aim of this review is to discuss the rationale, pr...

    Full Text Available The AMMI Canada meeting in March 2006 hosted a symposium exploring the potential alternatives to antibiotics for the prevention and treatment of infection. Four papers summarizing talks from that session are published in this issue of the Journal (1-4. These reviews address the scientific underpinnings for a number of proposed concepts, and summarize the current status of clinical use. The approaches - probiotics, bacteriophage therapy, and manipulation of innate immunity - are all intriguing but are still removed from immediate practical applications.

    This report synthesizes the knowledge, opinions, and concerns of many Federal and State land managers, scientists, stakeholders, and partners from a workshop, held at the University of Nevada, Las Vegas, on April 20-22, 2010. Land managers, research scientists, and resource specialists identified common concerns regarding the potential effects of climate change on public lands and natural resources in the Great Basin and Mojave Desert and developed recommendations for mitigation, adaptation, and research needs. Water and, conversely, the effects of drought emerged as a common theme in all breakout sessions on terrestrial and aquatic species at risk, managing across boundaries, monitoring, and ecosystem services. Climate change models for the southwestern deserts predict general warming and drying with increasing precipitation variability year to year. Scientists noted that under these changing conditions the past may no longer be a guide to the future in which managers envision increasing conflicts between human water uses and sustaining ecosystems. Increasing environmental stress also is expected as a consequence of shifting ecosystem boundaries and species distributions, expansion of non-native species, and decoupling of biotic mutualisms, leading to increasingly unstable biologic communities. Managers uniformly expressed a desire to work across management and agency boundaries at a landscape scale but conceded that conflicting agency missions and budgetary constraints often impede collaboration. More and better science is needed to cope with the effects of climate change but, perhaps even more important is the application of science to management issues using the methods of adaptive management based on long-term monitoring to assess the merits of management actions. Access to data is essential for science-based land management. Basic inventories, spatial databases, baseline condition assessments, data quality assurance, and data sharing were identified as top

    Canada's boreal forest supports many aquatic ecosystem services (AES) due to the intimate linkage between aquatic systems and their surrounding terrestrial watersheds in forested landscapes. There is an increasing risk to AES because natural development activities (forest management, mining, energy) have resulted in disruptions that deteriorate aquatic ecosystems at local (10s of km2) to regional (100s of km2) scales. These activities are intensifying and expanding, placing at risk the healthy aquatic ecosystems that provide AES and may threaten the continued development of the energy, forest, and mining sectors. Remarkably, we know little about the consequences of these activities on AES. The idea that AES should be explicitly integrated into modern natural resource management regulations is gaining broad acceptance. A major need is the ability to measure cumulative effects and determine thresholds (the points where aquatic ecosystems and their services cannot recover to a desired state within a reasonable time frame) in these cumulative effects. However, there is no single conceptual approach to assessing cumulative effects that is widely accepted by both scientists and managers. We present an integrated science-policy framework that enables the integration of AES into forest management risk assessment and prevention/mitigation strategies. We use this framework to explore the risk of further deterioration of AES by (1) setting risk criteria; (2) using emerging technologies to map process-based indicators representing causes and consequences of risk events to the deterioration of AES; (3) assessing existing prevention and mitigation policies in place to avoid risk events; and (4) identifying priorities for policy change needed to reduce risk event. Ultimately, the success of this framework requires that higher value be placed on AES, and in turn to improve the science and management of the boreal forest.

    Full Text Available Diabetes self-management education is crucial in diabetes care. Education that is tailored to the needs of the patient is considered the most effective in improving health outcomes. Diet, a critical element of diabetes treatment, is reported as the most difficult to adhere to by both patients and health professionals. Tailored nutrition education (NE could benefit diabetic individuals with low socio-economic status, who are amongst those noted to have poor health outcomes. This qualitative interpretive phenomenological study aimed to explore and describe the NE needs of adults with type 2 diabetes mellitus to guide development of a tailored NE programme for resource-poor settings. Participants were 31 non-insulin-dependent type 2 diabetic patients (convenience sample and 10 health professionals. Focus group discussions using semi-structured questions were held with the diabetics, and open-ended self-administered questionnaires were used with the health professionals. Data analysis was done using Krueger’s framework approach. Disease-related knowledge deficits and inappropriate self-reported dietary practices, including intake of unbalanced meals, problems with food portion control and unsatisfactory intake of fruits and vegetables, were observed. Recommendations for the NE programme included topics related to the disease and others related to diet. Group education at the clinic, a competent educator and comprehensive education were indicated by the patients. Participation of family and provision of pamphlets were aspects recommended by patients and health professionals. Barriers that could impact the NE included financial constraints, food insecurity, conflict in family meal arrangements and access to appropriate foods. Support from family and health professionals and empowerment through education were identified as facilitators to following dietary recommendations by both groups of participants.

  17. Environmental dissemination of antibiotic resistance genes and correlation to anthropogenic contamination with antibiotics

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Antibiotic resistance is a growing problem which threatens modern healthcare globally. Resistance has traditionally been viewed as a clinical problem, but recently non-clinical environments have been highlighted as an important factor in the dissemination of antibiotic resistance genes (ARGs. Horizontal gene transfer (HGT events are likely to be common in aquatic environments; integrons in particular are well suited for mediating environmental dissemination of ARGs. A growing body of evidence suggests that ARGs are ubiquitous in natural environments. Particularly, elevated levels of ARGs and integrons in aquatic environments are correlated to proximity to anthropogenic activities. The source of this increase is likely to be routine discharge of antibiotics and resistance genes, for example, via wastewater or run-off from livestock facilities and agriculture. While very high levels of antibiotic contamination are likely to select for resistant bacteria directly, the role of sub-inhibitory concentrations of antibiotics in environmental antibiotic resistance dissemination remains unclear. In vitro studies have shown that low levels of antibiotics can select for resistant mutants and also facilitate HGT, indicating the need for caution. Overall, it is becoming increasingly clear that the environment plays an important role in dissemination of antibiotic resistance; further studies are needed to elucidate key aspects of this process. Importantly, the levels of environmental antibiotic contamination at which resistant bacteria are selected for and HGT is facilitated at should be determined. This would enable better risk analyses and facilitate measures for preventing dissemination and development of antibiotic resistance in the environment.

  18. The actual status of uranium ore resources at Eko Remaja Sector: the need of verification of resources computation and geometrical form of mineralization zone by mining test

    International Nuclear Information System (INIS)

    Uranium ore resources calculation was done after ending all of geological work step. Estimation process of ore resources was started from evaluation drilling, continued with borehole logging. From logging, the result has presented in anomaly graphs, then was processed to determine thickness and grade value of ore. Those mineralization points were correlated one another to form mineralization zones which have direction of N 270 degree to N 285 degree with 70 degree dip to North. From Grouping the mineralization distribution, 19 mineralization planes was constructed which contain 553 ton of U3O8 measured. It is suggested that before expanding measured ore deposit area, mining test should be done first at certain mineralization planes to prove the method applied to calculate the reserve. Results form mining test could be very useful to reevaluate all the work-step done. (author); 4 refs; 2 tabs; 8 figs

No amikacin was found in the wastewater, but E.coli isolates from all wastewater samples were resistant to amikacin. Although ciprofloxacin was the most prevalent antibiotic detected in the wastewater, E.coli was not resistant to it. Conclusions Antibiotics are entering the aquatic environment of countries like India through hospital effluent. In-depth studies are needed to establish the correlation, if any, between the quantities of antibiotics prescribed in hospitals and the levels of antibiotic residues found in hospital effluent. Further, the effect of this on the development of bacterial resistance in the environment and its subsequent public health impact need thorough assessment.

    The global burden of antibiotic resistance is tremendous and, without new anti-infective strategies, will continue to increase in the coming decades. Despite the growing need for new antibiotics, few pharmaceutical companies today retain active antibacterial drug discovery programmes. One reason is that it is scientifically challenging to discover new antibiotics that are active against the antibiotic-resistant bacteria of current clinical concern. However, the main hurdle is diminishing economic incentives. Increased global calls to minimize the overuse of antibiotics, the cost of meeting regulatory requirements and the low prices of currently marketed antibiotics are strong deterrents to antibacterial drug development programmes. New economic models that create incentives for the discovery of new antibiotics and yet reconcile these incentives with responsible antibiotic use are long overdue. DRIVE-AB is a €9.4 million public-private consortium, funded by the EU Innovative Medicines Initiative, that aims to define a standard for the responsible use of antibiotics and to develop, test and recommend new economic models to incentivize investment in producing new anti-infective agents.

    Gyamfi, Alexander

    The purpose of this study was twofold. First, it identified the priority needs common to all science teachers in secondary schools in Kumasi, Ghana. Second, it investigated the relationship existing between the identified priority needs and the teacher demographic variables (type of school, teacher qualification, teaching experience, subject discipline, and sex of teacher) to be used as a basis for implementing in-service education training programs at the Science Resource Centers in Kumasi Ghana. An adapted version of the Moore Assessment Profile (MAP) survey instrument and a set of open-ended questions were used to collect data from the science teachers. The researcher handed out one hundred and fifty questionnaire packets, and all one hundred and fifty (100%) were collected within a period of six weeks. The data were analyzed using descriptive statistics, content analysis, and inferential statistics. The descriptive statistics reported the frequency of responses, and it was used to calculate the Need Index (N) of the identified needs of teachers. Sixteen top-priority needs were identified, and the needs were arranged in a hierarchical order according to the magnitude of the Need Index (0.000 ≤ N ≤ 1.000). Content analysis was used to analyze the responses to the open-ended questions. One-way analysis of variance (ANOVA) was used to test the null hypotheses of the study on each of the sixteen identified top-priority needs and the teacher demographic variables. The findings of this study were as follows: (1) The science teachers identified needs related to "more effective use of instructional materials" as a crucial area for in-service training. (2) Host and Satellite schools exhibited significant difference on procuring supplementary science books for students. Subject discipline of teachers exhibited significant differences on utilizing the library and its facilities by students, obtaining information on where to get help on effective science teaching

    The variability and uncertainty of wind power production requires increased flexibility in power systems, or more operational reserves to main a satisfactory level of reliability. The incremental increase in reserve requirement caused by wind power is often studied separately from the effects of loads. Accordingly, the cost in procuring reserves is allocated based on this simplification rather than a fair and transparent calculation of the different resources’ contribution to the reserve requirement. This work proposes a new allocation mechanism for intermittency and variability of resources regardless of their type. It is based on a new formula, called grid balancing metric (GBM). The proposed GBM has several distinct features: 1) it is directly linked to the control performance standard (CPS) scores and interconnection frequency performance, 2) it provides scientifically defined allocation factors for individual resources, 3) the sum of allocation factors within any group of resources is equal to the groups’ collective allocation factor (linearity), and 4) it distinguishes helpers and harmers. The paper illustrates and provides results of the new approach based on actual transmission system operator (TSO) data.

    2011-11-01

    Full Text Available Voluntary medical male circumcision (VMMC reduces female-to-male HIV transmission by approximately 60%; modeling suggests that scaling up VMMC to 80% of men 15- to 49-years-old within five years would avert over 3.3 million new HIV infections in 14 high priority countries/regions in southern and eastern Africa by 2025 and would require 20.33 million circumcisions. However, the shortage of health professionals in these countries must be addressed to reach these proposed coverage levels. To identify human resource approaches that are being used to improve VMMC volume and efficiency, we looked at previous literature and conducted a program review. We identified surgical efficiencies, non-surgical efficiencies, task shifting, task sharing, temporary redeployment of public sector staff during VMMC campaign periods, expansion of the health workforce through recruitment of unemployed, recently retired, newly graduating, or on-leave health care workers, and the use of volunteer medical staff from other countries as approaches that address human resource constraints. Case studies from Kenya, Tanzania, and Swaziland illustrate several innovative responses to human resource challenges. Although the shortage of skilled personnel remains a major challenge to the rapid scale-up of VMMC in the 14 African priority countries/regions, health programs throughout the region may be able to replicate or adapt these approaches to scale up VMMC for public health impact.

    2015-11-01

    Antibiotic resistance is a growing and worrying problem associated with increased deaths and suffering for people. Overall, there are only two factors that drive antimicrobial resistance, and both can be controlled. These factors are the volumes of antimicrobials used and the spread of resistant micro-organisms and/or the genes encoding for resistance. The One Health concept is important if we want to understand better and control antimicrobial resistance. There are many things we can do to better control antimicrobial resistance. We need to prevent infections. We need to have better surveillance with good data on usage patterns and resistance patterns available across all sectors, both human and agriculture, locally and internationally. We need to act on these results when we see either inappropriate usage or resistance levels rising in bacteria that are of concern for people. We need to ensure that food and water sources do not spread multi-resistant micro-organisms or resistance genes. We need better approaches to restrict successfully what and how antibiotics are used in people. We need to restrict the use of 'critically important' antibiotics in food animals and the entry of these drugs into the environment. We need to ensure that 'One Health' concept is not just a buzz word but implemented. We need to look at all sectors and control not only antibiotic use but also the spread and development of antibiotic resistant bacteria - both locally and internationally. PMID:26563691

    Full Text Available Antibiotic resistance has become an urgent and global issue, with 700,000 deaths attributable to multidrug-resistance occurring each year worldwide. The overuse of antibiotics, both in animal industry and in clinical settings, and the generated selective pressure, are the main factors implicated in the emergence of resistant strains. The Centers for Disease Control and Prevention (CDC have pointed out that more than half of hospital patients receive an antibiotic during their stay, and nearly a third receive a broad-spectrum antibiotic. In neonatal units, previous antibiotic exposure to third-generation cephalosporin and carbapenem were identified as independent risk factors for infection caused by multi-drug resistant strains. While resistant ‘superbugs’ emerge, the arsenal to fight these microorganisms is progressively shrinking, as the number of newly discovered antibiotics approved by the Food and Drug administration each year is dropping. In face of global spread of antibiotic resistance and of the limited development of new drugs, policies and rules are under study by agencies (CDC, World Health Organization and governments, in order to: i facilitate and foster the discovery of new antibiotic compounds; ii develop new, alternative therapies able to potentiate or modulate the host immune response or to abrogate the resistance and virulence factors in the microorganisms; and iii prevent the emergence of resistance through antibiotic stewardship programs, educational programs, and reduction of antibiotic use in livestock; the field of neonatal medicine will need its own, newborn-tailored, antibiotic stewardship programs to be implemented in the NICUs. Proceedings of the 11th International Workshop on Neonatology and Satellite Meetings · Cagliari (Italy · October 26th-31st, 2015 · From the womb to the adultGuest Editors: Vassilios Fanos (Cagliari, Italy, Michele Mussap (Genoa, Italy, Antonio Del Vecchio (Bari, Italy, Bo Sun (Shanghai

    International Nuclear Information System (INIS)

    The temperature of earth planet is rising at an alarming rate and environmental changes, green house gasses emission and atmospheric pollution are approaching very critical limits. Ozone layer hole is increasing at very fast rate. On account of these very serious issues, the earth planet is heading at a very fast rate towards total collapse of life on it. For overcoming these very dangerous global problems Pakistan has very ideal resources subject to their proper management and well planned and timely mobilization. The efficient scientific utilization of these resources will not resolve its own pollution problems along contributing towards its own agricultural, industrial and economic growth, but also heavily contribute to the very critical global issues endangering the very existence of life on the earth along with contributing towards its own agricultural, industrial and economic growth. This will also forbid it to join hand with the rations already engaged in contributing toward the world's destruction by adding to these highly dangerous factors. In this work role of proper management of its water flow, gradient and storage resources in hydroelectric power generation and irrigation of its vast fertile agricultural fields and substantial control of these very dangerous global issues in highlighted. Also the economic boost of Pakistan due to its firm footing in respect economy, agricultural and industrial output, energy employment and flood damages control as a result of this mobilization is elaborated. At the end world's political leaders, electronic media, scientific and financial institutions are urged to help Pakistan in playing its role not only for welfare but very existence of mankind on this planet.

    2003-01-01

    Full Text Available Nearly 25% of antibiotic associated diarrhoeas (AAD is caused by Clostridium difficile, making it the commonest identified and treatable pathogen. Other pathogens implicated infrequently include Clostridium perfringens, Staphylococcus aureus, Klebsiella oxytoca, Candida spp. and Salmonella spp. Most mild cases of AAD are due to non-infectious causes which include reduced break down of primary bile acids and decrease metabolism of carbohydrates, allergic or toxic effects of antibiotic on intestinal mucosa and pharmacological effect on gut motility. The antibiotics most frequently associated with C. difficile associated diarrhoea are clindamycin, cephalosporin, ampicillin and amoxicillin. Clinical presentation may vary from mild diarrhoea to severe colitis and pseudomembranous colitis associated with high morbidity and mortality. The most sensitive and specific diagnostic test for C. difficile infection is tissue culture assay for cytotoxicity of toxin B. Commercial ELISA kits are available. Though less sensitive, they are easy to perform and are rapid. Withdrawal of precipitating antibiotic is all that is needed for control of mild to moderate cases. For severe cases of AAD, oral metronidazole is the first line of treatment, and oral vancomycin is the second choice. Probiotics have been used for recurrent cases.

    In 2000, NETL conducted a review of the adequacy of the resource characterization databases used in its Gas Systems Analysis Model (GSAM). This review indicated that the most striking deficiency in GSAM’s databases was the poor representation of the vast resource believed to exist in low-permeability sandstone accumulations in western U.S. basins. The model’s databases, which are built primarily around the United States Geological Survey (USGS) 1995 National Assessment (for undiscovered resources), reflected an estimate of the original-gas-inplace (OGIP) only in accumulations designated “technically-recoverable” by the USGS –roughly 3% to 4% of the total estimated OGIP of the region. As these vast remaining resources are a prime target of NETL programs, NETL immediately launched an effort to upgrade its resource characterizations. Upon review of existing data, NETL concluded that no existing data were appropriate sources for its modeling needs, and a decision was made to conduct new, detailed log-based, gas-in-place assessments.

    The purpose of this document is to provide guidance to developers of small-scale hydroelectric projects on the assessment of instream flow needs. While numerous methods have been developed to assess the effects of stream flow regulation on aquatic biota in coldwater streams in the West, no consensus has been reached regarding their general applicability, especially to streams in the eastern United States. This report presents and reviews these methods (Section 2.0), which is intended to provide the reader with general background information that is the basis for the critical evaluation of the methods (Section 3.0). The strategy for instream flow assessment presented in Section 4.0 is, in turn, based on the implicit assumptions, data needs, costs, and decision-making capabilities of the various methods as discussed in Section 3.0.

  20. Plasmid encoded antibiotic resistance: acquisition and transfer of antibiotic resistance genes in bacteria.

    Bacteria have existed on Earth for three billion years or so and have become adept at protecting themselves against toxic chemicals. Antibiotics have been in clinical use for a little more than 6 decades. That antibiotic resistance is now a major clinical problem all over the world attests to the success and speed of bacterial adaptation. Mechanisms of antibiotic resistance in bacteria are varied and include target protection, target substitution, antibiotic detoxification and block of intracellular antibiotic accumulation. Acquisition of genes needed to elaborate the various mechanisms is greatly aided by a variety of promiscuous gene transfer systems, such as bacterial conjugative plasmids, transposable elements and integron systems, that move genes from one DNA system to another and from one bacterial cell to another, not necessarily one related to the gene donor. Bacterial plasmids serve as the scaffold on which are assembled arrays of antibiotic resistance genes, by transposition (transposable elements and ISCR mediated transposition) and site-specific recombination mechanisms (integron gene cassettes).The evidence suggests that antibiotic resistance genes in human bacterial pathogens originate from a multitude of bacterial sources, indicating that the genomes of all bacteria can be considered as a single global gene pool into which most, if not all, bacteria can dip for genes necessary for survival. In terms of antibiotic resistance, plasmids serve a central role, as the vehicles for resistance gene capture and their subsequent dissemination. These various aspects of bacterial resistance to antibiotics will be explored in this presentation. PMID:18193080

    The worldwide escalation of bacterial resistance to conventional medical antibiotics is a serious concern for modern medicine. High prevalence of multidrug-resistant bacteria among bacteria-based infections decreases effectiveness of current treatments and causes thousands of deaths. New improvements in present methods and novel strategies are urgently needed to cope with this problem. Owing to their antibacterial activities, metallic nanoparticles represent an effective solution for overcoming bacterial resistance. However, metallic nanoparticles are toxic, which causes restrictions in their use. Recent studies have shown that combining nanoparticles with antibiotics not only reduces the toxicity of both agents towards human cells by decreasing the requirement for high dosages but also enhances their bactericidal properties. Combining antibiotics with nanoparticles also restores their ability to destroy bacteria that have acquired resistance to them. Furthermore, nanoparticles tagged with antibiotics have been shown to increase the concentration of antibiotics at the site of bacterium-antibiotic interaction, and to facilitate binding of antibiotics to bacteria. Likewise, combining nanoparticles with antimicrobial peptides and essential oils generates genuine synergy against bacterial resistance. In this article, we aim to summarize recent studies on interactions between nanoparticles and antibiotics, as well as other antibacterial agents to formulate new prospects for future studies. Based on the promising data that demonstrated the synergistic effects of antimicrobial agents with nanoparticles, we believe that this combination is a potential candidate for more research into treatments for antibiotic-resistant bacteria.

    The Conservation Effects Assessment Project (CEAP) was initiated to quantify the impacts of agricultural conservation practices at the watershed, regional, and national scales across the United States. Representative cropland acres in all major U.S. watersheds were surveyed in 2003-2006 as part of the seminal CEAP Cropland National Assessment. Two process-based models, the Agricultural Policy Environmental eXtender(APEX) and the Soil Water Assessment Tool (SWAT), were applied to the survey data to provide a quantitative assessment of current conservation practice impacts, establish a benchmark against which future conservation trends and efforts could be measured, and identify outstanding conservation concerns. The flexibility of these models and the unprecedented amount of data on current conservation practices across the country enabled Cropland CEAP to meet its Congressional mandate of quantifying the value of current conservation practices. It also enabled scientifically grounded exploration of a variety of conservation scenarios, empowering CEAP to not only inform on past successes and additional needs, but to also provide a decision support tool to help guide future policy development and conservation practice decision making. The CEAP effort will repeat the national survey in 2015-2016, enabling CEAP to provide analyses of emergent conservation trends, outstanding needs, and potential costs and benefits of pursuing various treatment scenarios for all agricultural watersheds across the United States.

    International Nuclear Information System (INIS)

    Study of the structure of antibiotics having two or several sugars in their molecule. One may distinguish: the polysaccharide antibiotics themselves, made up of two or several sugars either with or without nitrogen, such as streptomycin, neomycins, paromomycine, kanamycin, chalcomycin; the hetero-polysaccharide antibiotics made up of one saccharide part linked to an aglycone of various type through a glucoside: macrolide, pigment, pyrimidine purine. Amongst these latter are: erythromycin, magnamycin, spiramycin, oleandomycin, cinerubin and amicetin. The sugars can either play a direct role in biochemical reactions or act as a dissolving agent, as far as the anti-microbe power of these antibiotics is concerned. (author)

    2014-04-01

    Full Text Available Microbial pollution in aquatic environments is one of the crucial issues with regard to the sanitary state of water bodies used for drinking water supply, recreational activities and harvesting seafood due to a potential contamination by pathogenic bacteria, protozoa or viruses. To address this risk, microbial contamination monitoring is usually assessed by turbidity measurements performed at drinking water plants. Some recent studies have shown significant correlations of microbial contamination with the risk of endemic gastroenteresis. However the relevance of turbidimetry may be limited since the presence of colloids in water creates interferences with the nephelometric response. Thus there is a need for a more relevant, simple and fast indicator for microbial contamination detection in water, especially in the perspective of climate change with the increase of heavy rainfall events. This review focuses on the one hand on sources, fate and behavior of microorganisms in water and factors influencing pathogens’ presence, transportation and mobilization, and on the second hand, on the existing optical methods used for monitoring microbiological risks. Finally, this paper proposes new ways of research.

    Full Text Available Introduction. Antimicrob drugs and immune system interaction has been studied since the pioneer works of Metchnikoff. After the introduction of antibiotics in clinical practice this area has attracted little attention of investigators, because of the lack of standards. This is the reason that the studying of the influence of antibiotics on immune system is still at its beginning. Aim: To point out the immunomodulatory action of some antibiotics on certain components of immune system. Methods and results. The literaure findings show that antibiotics exspress immunomodulatory action on some components of immune system such as fagocytes (polymorphonucleary, macrophages, monocytes, cytokines, immunoglobulines, and on cellular immunity. The principles of antibiotics action on phagocyte are the inhibition of chemotaxis and oxidants production. Macrolides applied for a short time enchance the phagocytic functions while their long use leads to immunosupression. Some cephalosporines and rifampicin in therapeutic doses inhibit the oxydative metabolism of macrophages. Tetracyclines, clindamycines, chloramphenicol and tobramycin inhibit the synthesis of superoxyd anione. The action of some antibiotics on cytokine and specific antibodies is also important. Cellular immunity can be affected as well. After administration of certain antibiotics it takes 1-2 weeks to reestablish normal cellular immunity, and for other even more. Conclusion. There is still no clear standing on real effects of antibiotics on the immune system. Clinicians should search for more information from this new-old field of investigation in order to give more adequate therapy to patients.

    Full Text Available The use of antibiotics in food-producing animals has significantly increased animal health by lowering mortality and the incidence of diseases. Antibiotics also have largely contributed to increase productivity of farms. However, antibiotic usage in general and relevance of non-therapeutic antibiotics in feed (growth promoters need to be reevaluated especially because bacterial pathogens of humans and animals have developed and shared a variety of antibiotic resistance mechanisms that can easily spread within microbial communities. In Canada, poultry production involves more than 2,600 regulated chicken producers. There are several antibiotics approved as feed additives available for poultry farmers.

    Catfish is one of the most cultivated species worldwide. Antibiotics are usually used in catfish farming as therapeutic and prophylactic agents. In the USA, only oxytetracycline, a combination of sulfadimethoxine and ormetoprim, and florfenicol are approved by the Food Drug Administration for specific fish species (e.g., catfish and salmonids) and their specific diseases. Misuse of antibiotics as prophylactic agents in disease prevention, however, is common and contributes in the development of antibiotic resistance. Various studies had reported on antibiotic residues and/or resistance in farmed species, feral fish, water column, sediments, and, in a lesser content, among farm workers. Ninety percent of the world aquaculture production is carried out in developing countries, which lack regulations and enforcement on the use of antibiotics. Hence, efforts are needed to promote the development and enforcement of such a regulatory structure. Alternatives to antibiotics such as antibacterial vaccines, bacteriophages and their lysins, and probiotics have been applied to curtail the increasing emergence of antibiotic-resistant bacteria due to the imprudent application of antibiotics in aquaculture.

  15. Antibiotics in acute necrotizing pancreatitis --- perspective of a developing country

    International Nuclear Information System (INIS)

    Prophylactic antibiotics in acute necrotizing pancreatitis is controversial. The mortality of acute necrotizing pancreatitis is 8-25% in the western world. In view of the limited resources available for managing the complications of infected pancreatitis in developing countries, the use of prophylactic antibiotics may be recommended in selected cases. Various antibiotics show good penetration into the pancreatic tissue; imipenem and quinolones have better penetration. Clinical trials on the use of prophylactic antibiotics in necrotizing pancreatitis have been reviewed. Prophylactic antibiotics have been considered if greater than 30% pancreatic necrosis as documented by CT scan. Imipenem can be given for a duration of 10 to 14 days if no systemic complications are present. In a developing country where the cost of managing complications of pancreatitis can be a limiting factor for patients, the use of prophylactic antibiotics early on in the disease in selected cases can be beneficial.

  16. Public Beliefs about Antibiotics, Infection and Resistance: A Qualitative Study

    Directory of Open Access Journals (Sweden)

    Helen Madden

    2013-11-01

    Full Text Available We aimed to gain an in-depth understanding of public views and ways of talking about antibiotics. Four focus groups were held with members of the public. In addition, 39 households were recruited and interviews, diaries of medicine taking, diaries of any contact with medication were used to explore understanding and use of medication. Discussions related to antibiotics were identified and analyzed. Participants in this study were worried about adverse effects of antibiotics, particularly for recurrent infections. Some were concerned that antibiotics upset the body’s “balance”, and many used strategies to try to prevent and treat infections without antibiotics. They rarely used military metaphors about infection (e.g., describing bacteria as invading armies but instead spoke of clearing infections. They had little understanding of the concept of antibiotic resistance but they thought that over-using antibiotics was unwise because it would reduce their future effectiveness. Previous studies tend to focus on problems such as lack of knowledge, or belief in the curative powers of antibiotics for viral illness, and neglect the concerns that people have about antibiotics, and the fact that many people try to avoid them. We suggest that these concerns about antibiotics form a resource for educating patients, for health promotion and social marketing strategies.

  17. Energy needs

    International Nuclear Information System (INIS)

    There seems to be a trend towards expecting energy conservation to be a panacea for the world's ills. In fact, a global perspective on energy needs shows that more, not less, energy is needed and technological innovation in energy sources is essential in order to meet the needs of more than just the developed countries. Energy-intensive technology is the amplification of our natural resources rather than their depletion. A fundamental bioethical principle must be established if we are to analyze and organize scientific evidence about hazards from currently feasible energy resources, and separate genuine from counterfeit claims to credibility. In particular, public fears about radiation hazards and radioactive waste disposal are influenced too much by rhetorical cleverness and forensic skills of a vociferous minority. Potential hazard management is ethically equitable only if it is proportioned to actual basic harm that can be identified and reduced by expenditures of human effort, time and money

    Finding strategies against the development of antibiotic resistance is a major global challenge for the life sciences community and for public health. The past decades have seen a dramatic worldwide increase in human-pathogenic bacteria that are resistant to one or multiple antibiotics. More and more infections caused by resistant microorganisms fail to respond to conventional treatment, and in some cases, even last-resort antibiotics have lost their power. In addition, industry pipelines for the development of novel antibiotics have run dry over the past decades. A recent world health day by the World Health Organization titled "Combat drug resistance: no action today means no cure tomorrow" triggered an increase in research activity, and several promising strategies have been developed to restore treatment options against infections by resistant bacterial pathogens.

    Introduction. The aim of our study is to assess the need for postoperative antibiotics following simple exodontia and determine its role in minimizing patient discomfort and postoperative complications. Material and Methods. All the patients undergoing simple extractions were grouped into two categories: Group 1, patients receiving antibiotics, and Group 2, patients receiving no antibiotics. Patients were recalled on the sixth day to assess postoperative complications. On recall, patients were evaluated for signs of persistent inflammation and signs of dry socket. Presence of persistent inflammation and/or suppuration on the 6th day was considered as wound infection. Results. A total of 146 patients were included in this study. Out of the total sample, 134 (91.8%) presented with no postoperative complications and 12 (8.2%) had postoperative complications, out of which 11 (7.5%) patients presented with dry socket (alveolar osteitis), 5 (3.4%) in the antibiotic group and 6 (4.1%) in the nonantibiotic group. Only 1 patient (0.7%) was reported with infection of the extraction socket in the nonantibiotic group, whereas no case of infection was found in the antibiotic group. Conclusion. Antibiotics are not required after simple extractions in patients who are not medically comprised nor do they have any role in preventing postoperative complications. PMID:27110426

    2012-04-01

    The intrinsic and acquired resistance of Mycobacterium abscessus to commonly used antibiotics limits the chemotherapeutic options for infections caused by these mycobacteria. Intrinsic resistance is attributed to a combination of the permeability barrier of the complex multilayer cell envelope, drug export systems, antibiotic targets with low affinity and enzymes that neutralize antibiotics in the cytoplasm. To date, acquired resistance has only been observed for aminoglycosides and macrolides, which is conferred by mutations affecting the genes encoding the antibiotic targets (rrs and rrl, respectively). Here we summarize previous and recent findings on the resistance of M. abscessus to antibiotics in light of what has been discovered for other mycobacteria. Since we can now distinguish three groups of strains belonging to M. abscessus (M. abscessus sensu stricto, Mycobacterium massiliense and Mycobacterium bolletii), studies on antibiotic susceptibility and resistance should be considered according to this new classification. This review raises the profile of this important pathogen and highlights the work needed to decipher the molecular events responsible for its extensive chemotherapeutic resistance. PMID:22290346

    Full Text Available Self medication with antibiotics has become a common practice among people, and more so among those with medical background. Dentists are one group who have kno wledge and accessibility to antibiotics. Hence this study was aimed at knowing the prevalence of self medication with antibiotics among dentists reasons for not visiting the physician. RESULT: Prevalence rate of self medication among dentist was 78.18%. Mo st common cause for self medication were common cold, tooth ache and sore throat. Most common antibiotic used was azithromycin next to ampicillin. Most common reason for not visiting doctor was that participants were themselves a doctor. CONCLUSION: Though dentists have knowledge about antibiotics, knowledge on appropriate usage of antibiotics is poor. This may have a bad impact on practice. Hence they have to overcome the ego and take proper advice from physician which may help the community in curbing ant ibiotic resistance The only limitation of the study was small sample size as dentists from only two colleges were considered. There is a need for study in large number of population.

    From December 2005 to April 2007, we enrolled 60 adults starting antiretroviral therapy (ART) in Lima, Peru to receive community-based accompaniment with supervised antiretrovirals (CASA), consisting of 12 months of DOT-HAART, as well as microfinance assistance and/or psychosocial support group according to individuals' need. We matched 60 controls from a neighboring district, and assessed final clinical and psychosocial outcomes at 24 months. CASA support was associated with higher rates of virologic suppression and lower mortality. A comprehensive, tailored adherence intervention in the form of community-based DOT-HAART and matched economic and psychosocial support is both feasible and effective for certain individuals in resource-poor settings.

    Full Text Available It is a commonplace that water is essential for life, but to what extent is the general public, and children in particular, aware of how water affects health? The aim of this review was to consider the relationship between water and health under three main headings: the importance of hydration for children, dietary intake of water, and water as an essential factor in hygiene contributing to good health. The literature was reviewed to provide a rationale for the implementation of teaching about water and health in French primary schools under three main areas: (i the importance of hydration for school children and water promotion in primary schools; (ii the problem of overweight/obesity and the need to adopt healthy drinking habits as defined in French nutritional policy; (iii the survey of the quality of drinking water in France and its relationship with good hygiene practices. There are currently few educational resources in France on water and health that teachers can use in the classroom. This review gives reasons why a “Water and Health” learning resource is a useful tool and shows how it can be developed within the constraints imposed by the school syllabus and in accordance with French nutritional and environmental policy.

  7. Phenotypic Resistance to Antibiotics

    Full Text Available The development of antibiotic resistance is usually associated with genetic changes, either to the acquisition of resistance genes, or to mutations in elements relevant for the activity of the antibiotic. However, in some situations resistance can be achieved without any genetic alteration; this is called phenotypic resistance. Non-inherited resistance is associated to specific processes such as growth in biofilms, a stationary growth phase or persistence. These situations might occur during infection but they are not usually considered in classical susceptibility tests at the clinical microbiology laboratories. Recent work has also shown that the susceptibility to antibiotics is highly dependent on the bacterial metabolism and that global metabolic regulators can modulate this phenotype. This modulation includes situations in which bacteria can be more resistant or more susceptible to antibiotics. Understanding these processes will thus help in establishing novel therapeutic approaches based on the actual susceptibility shown by bacteria during infection, which might differ from that determined in the laboratory. In this review, we discuss different examples of phenotypic resistance and the mechanisms that regulate the crosstalk between bacterial metabolism and the susceptibility to antibiotics. Finally, information on strategies currently under development for diminishing the phenotypic resistance to antibiotics of bacterial pathogens is presented.

    Because of a low risk of infection (around 2-3%), prophylactic use of antibiotics in neurosurgery is a controversial issue. Some neurosurgeons consider that there are strong arguments against the use of antimicrobials (promotion of antibiotic-resistant strains of bacteria, superinfection and adverse drug reactions) and meticulous aseptic techniques could be more usefully than prophylactic antibiotics. On the other hand, despite of being rare, the consequences of a neurosurgical infection can be dramatic and may result in a rapid death, caused by meningitis, cerebritis, abscess formation or sepsis. Clinical studies emphasized that the most important factors influencing the choice of antibiotic prophylaxis in neurosurgery is the patient's immune status, virulence of the pathogens and the type of surgery ("clean contaminated"--procedure that crosses the cranial sinuses, "clean non-implant"--procedure that does not cross the cranial sinuses, CSF shunt surgery, skull fracture). Prophylaxis has become the standard of care for contaminated and clean-contaminated surgery, also for surgery involving insertion of artificial devices. The antibiotic (first/second generation of cephalosporins or vancomycin in allergic patients) should recover only the cutaneous possibly contaminating flora (S. aureus, S. epidermidis) and should be administrated 30' before the surgical incision, intravenously in a single dose. Most studies pointed that identification of the risk factors for infections, correct asepsis and minimal prophylactic antibiotic regimen, help neurosurgeons to improve patient care and to decrease mortality without selecting resistant bacteria.

    Full Text Available Antibiotic resistance can be reduced by using antibiotics prudently based on guidelines of antimicrobial stewardship programs (ASPs and various data such as pharmacokinetic (PK and pharmacodynamic (PD properties of antibiotics, diagnostic testing, antimicrobial susceptibility testing (AST, clinical response, and effects on the microbiota, as well as by new antibiotic developments. The controlled use of antibiotics in food animals is another cornerstone among efforts to reduce antibiotic resistance. All major resistance-control strategies recommend education for patients, children (e.g., through schools and day care, the public, and relevant healthcare professionals (e.g., primary-care physicians, pharmacists, and medical students regarding unique features of bacterial infections and antibiotics, prudent antibiotic prescribing as a positive construct, and personal hygiene (e.g., handwashing. The problem of antibiotic resistance can be minimized only by concerted efforts of all members of society for ensuring the continued efficiency of antibiotics.

    one correct answer was due to the answers from 5 (10.9% questions changing from correct to incorrect, while the answers to 6 questions (13.0% changed from incorrect to correct. The ability to provide correct answers differed among the various resources. Google and Cochrane provided the correct answers about 50% of the time while PubMed, Ovid MEDLINE, UpToDate, Ovid Evidence Based Medicine Reviews and InfoPOEMs were more likely to be associated with incorrect answers. Physicians also seemed unable to determine when they needed to search for informationi n order to make an accurate decision.Conclusion – Clinician‐selected electronic information resources did not guarantee accuracy in the answers provided to simulated clinical questions. At times the use of these resources caused physicians to change self‐determined correct answers to incorrect ones. The authors state that this was possibly due to factors such as poor choice of resources, ineffective search strategies, time constraints and automation bias. Library and information practitioners have an important role to play in identifying and advocating for appropriate information resources to be integrated into the electronic medical record systems provided by healthcare institutions to ensure evidence based health care delivery.

    Høiby, N

    2000-09-01

    Development of resistance to antibiotics is a major problem worldwide. The normal oropharyngeal flora, the intestinal flora and the skin flora play important roles in this development. Within a few days after the onset of antibiotic therapy, resistant Escherichia coli, Haemophilus influenzae and Staphylococcus epidermidis can be detected in the normal flora of volunteers or patients. Horizontal spread of the resistance genes to other species, e.g. Salmonella spp., Staphylococcus aureus and Streptococcus pneumoniae, occurs by conjugation or transformation. An ecologically sound antibiotic policy favours the use of antibiotics with little or no impact on the normal flora. Prodrug antibiotics which are not active against the bacteria in the mouth and the intestine (before absorption) and which are not excreted to a significant degree via the intestine, saliva or skin are therefore preferred. Prodrugs such as pivampicillin, bacampicillin, pivmecillinam and cefuroxime axetil are favourable from an ecological point of view. Experience from Scandinavia supports this, since resistance to mecillinam after 20 years of use is low (about 5%) and stable. PMID:11051626

    Full Text Available Antibiotics are chemotherapeutic agents, which have been a very powerful tool in the clinical management of bacterial diseases since the 1940s. However, benefits offered by these magic bullets have been substantially lost in subsequent days following the widespread emergence and dissemination of antibiotic resistant strains. While it is obvious that excessive and imprudent use of antibiotics significantly contributes to the emergence of resistant strains, antibiotic-resistance is also observed in natural bacteria of remote places unlikely to be impacted by human intervention. Both antibiotic biosynthetic genes and resistance-conferring genes have been known to evolve billions of years ago, long before clinical use of antibiotics. Hence it appears that antibiotics and antibiotics resistance determinants have some other roles in nature, which often elude our attention because of overemphasis on the therapeutic importance of antibiotics and the crisis imposed by the antibiotic-resistance in pathogens. In the natural milieu, antibiotics are often found to be present in subinhibitory concentrations acting as signalling molecules supporting quorum sensing and biofilm formation. They also play an important role in the production of virulence factors and influence host-parasite interactions (e.g., phagocytosis, adherence to the target cell and so on. The evolutionary and ecological aspects of antibiotics and antibiotic-resistance in the naturally occurring microbial community are little understood. Therefore, the actual role of antibiotics in nature warrants in-depth investigations. Studies on such an intriguing behaviour of the microorganisms promise insight into the intricacies of the microbial physiology and are likely to provide some lead in controlling the emergence and subsequent dissemination of antibiotic resistance. This article highlights some of the recent findings on the role of antibiotics and genes that confer resistance to antibiotics in

    The observed long-term trends, variability and projections of future climate and hydrology of the Chu and Talas transboundary rivers basin were analysed using a common approach for Kazakhstan and Kyrgyzstan parts of the basin. Historical, current and forecasted demands and main uses of water in the basin were elaborated by the joint effort of both countries. Such cooperative approach combining scientific data, water practitioners' outlook with decision making needs allowed the first time to produce a comprehensive assessment of climate change impacts on water resources in the Chu-Talas transboundary rivers basin, identify future needs and develop the initial set of adaptation measures and recommendations. This work was carried out under the project "Promoting Cooperation to Adapt to Climate Change in the Chu and Talas Transboundary Basin", supported by the United Nations Economic Commission for Europe (UNECE) and the United Nations Development Programme (UNDP). Climate change projections, including air temperatures and rainfall in the 21st century were determined with a spatial resolution 0.5 degrees based on the integration of 15 climate change model outputs (derived from IPCC's 4th Assessment Report, and partially 5th Assessment Report) combined with locally-designed hydrology and glacier models. A significant increase in surface air temperatures by 3-6°C may be expected in the basin area, especially in summer and autumn. This change is likely to be accompanied by rainfall increase during the cold season and a decrease in the warm half of the year. As a result, a deterioration of moisture conditions during the summer-autumn period is possible. Furthermore, milder winters and hotter summers can be expected. Mountains will likely receive more liquid precipitation, than snow, while the area and volume of glaciers may significantly reduce. Projected changes in climate and glaciers have implications for river hydrology and different sectors of the economy dependent

    Gynecological surgery is considered to be clear with possible contamination by gram-positive cocci from the skin, gram-negatives from the perineum or groins or polymicrobial biocenosis from vagina, depending on the surgical approach. Antibiotical prophylaxy enforces the natural mechanisms of immunity and helps to exclude present infection. There were presented many studies comparing useful effect of prophylaxis in gynecological surgery. The benefits of antibiotical prophylaxy before IUD insertion, before the cervical surgery and before hysteroscopies were not verified. On the other hand the prophylaxy of vaginal surgery including vaginal hysterectomy decreases the number of postoperative febrile complications. The positive influence of prophylaxis before the simple laparoscopy and laparoscopy without bowel injury or the opening of the vagina was not evidently verified. In abdominal hysterectomy the antibiotical prophylaxy decreases the incidence of postoperative complications significantly. The administration of 2 g of cefazolin can be recommended. In procedures taking more than 3 hours the repeated administration of cefazolin is suitable. New urogynecological procedures, using mesh implants, were not sufficiently evaluated as for postoperative infections and the posible antibiotical effect. The presence of implant in possibly non sterile area should be considered as high risc of postoperative complications. PMID:24040985

    International Nuclear Information System (INIS)

    The range and number of interventional procedures is rapidly increasing each year. A major complication associated with many procedures is infection, which can result in serious adverse outcomes for the patient. Consequently, antibiotics are amongst the most common pharmaceuticals used by the interventionist, particularly for non-vascular procedures, yet almost no randomized controlled trial data exist to inform our decision when formulating appropriate antibiotic prophylaxis regimens. The purpose of this review is to provide an update on the utilization of antibiotics for common interventional radiology procedures, focusing on timing and duration of antibiotic prophylaxis. - Highlights: • Prophylaxis when necessary should be given immediately prior to the procedure for optimum effect. • Where possible single agents with a narrow spectrum of activity should be used. • Account should be taken of the clinical circumstances of the patient, including surgical history. • Continuous review of agents is necessary, ideally with input from the local microbiology department. • The importance of maximum sterile precautions cannot be overstated

    Full Text Available AIMS AND OBJECTIVES: To compare if single dose antibiotic is as effective as multiple doses in prevention of post-operative infection in caesarean section. To compare the cost effectiveness of drugs in both the groups. MATERIAL AND METHOD: This prospective randomized controlled study was carried out to evaluate the effectiveness of single dose antibiotic versus multiple doses in caesarean section. The study population consisted of 600 patients that were randomly allocated to single or multiple dose groups. All potentially infected cases were excluded from this study. All patients received inj Cefotaxime IV half hour before surgery. In addition the multiple dose group received antibiotics for five days post-operatively. Each patient in the study was observed till discharge for presence of any morbidity like endometritis, urinary tract infections, and wound infections. STATISTICAL ANALYSISIS: Fischer exact test, unpaired t test used for analysis. RESULTS: There was no statistically significance in the rate of infections in both the groups. The rate of febrile morbidity, endometritis, urinary tract infection and wound infections were statistically not significant. However the difference in cost of antibiotic in both the groups was significant. CONCLUSIONS: Single dose antibiotics are effective as multiple doses in prevention of post-operative infections in caesarean sections Careful periodic surveillance of antibiotic prophylaxis is necessary to detect the emergence of drug resistant strains of bacteria in our institution because it caters to the needs of local population.

    Full Text Available Antibiotic resistance genes (ARGs have been commonly reported due to the overuse worldwide of antibiotics. Antibiotic overuse disturbs the environment and threatens public human health. The objective of this study was to measure the residual concentrations of veterinary antibiotics in the tetracycline group (TCs, including tetracycline (TC and chlortetracycline (CTC, as well as those in the sulfonamide group (SAs, including sulfamethazine (SMT, sulfamethoxazole (SMX, and sulfathiazole (STZ. We also isolated the corresponding ARGs in the agroecosystem. Four sediment samples and two rice paddy soil samples were collected from sites near a swine composting facility along the Naerincheon River in Hongcheon, Korea. High performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS was employed with a solid-phase extraction method to measure the concentration of each antibiotic. ARGs were identified by the qualitative polymerase chain-reaction using synthetic primers. SAs and their corresponding ARGs were highly detected in sediment samples whereas TCs were not detected except for sediments sample #1. ARGs for TCs and SAs were detected in rice paddy soils, while ARGs for TCs were only found in sediment #2 and #4. Continuous monitoring of antibiotic residue and its comprehensive impact on the environment is needed to ensure environmental health.

  3. Environmental pollution by antibiotics and by antibiotic resistance determinants

    International Nuclear Information System (INIS)

    Antibiotics are among the most successful drugs used for human therapy. However, since they can challenge microbial populations, they must be considered as important pollutants as well. Besides being used for human therapy, antibiotics are extensively used for animal farming and for agricultural purposes. Residues from human environments and from farms may contain antibiotics and antibiotic resistance genes that can contaminate natural environments. The clearest consequence of antibiotic release in natural environments is the selection of resistant bacteria. The same resistance genes found at clinical settings are currently disseminated among pristine ecosystems without any record of antibiotic contamination. Nevertheless, the effect of antibiotics on the biosphere is wider than this and can impact the structure and activity of environmental microbiota. Along the article, we review the impact that pollution by antibiotics or by antibiotic resistance genes may have for both human health and for the evolution of environmental microbial populations. - The article reviews the current knowledge on the effects that pollution by antibiotics and antibiotic resistance genes may have for the microbiosphere.

  4. Combined administration of antibiotics and direct oral anticoagulants: a renewed indication for laboratory monitoring?

    2014-10-01

    The recent development and marketing of novel direct oral anticoagulants (DOACs) represents a paradigm shift in the management of patients requiring long-term anticoagulation. The advantages of these compounds over traditional therapy with vitamin K antagonists include a reportedly lower risk of severe hemorrhages and the limited need for laboratory measurements. However, there are several scenarios in which testing should be applied. The potential for drug-to-drug interaction is one plausible but currently underrecognized indication for laboratory assessment of the anticoagulant effect of DOACs. In particular, substantial concern has been raised during Phase I studies regarding the potential interaction of these drugs with some antibiotics, especially those that interplay with permeability glycoprotein (P-gp) and cytochrome 3A4 (CYP3A4). A specific electronic search on clinical trials published so far confirms that clarithromycin and rifampicin significantly impair the bioavailability of dabigatran, whereas clarithromycin, erythromycin, fluconazole, and ketoconazole alter the metabolism of rivaroxaban in vivo. Because of their more recent development, no published data were found for apixaban and edoxaban, or for potential interactions of DOACs with other and widely used antibiotics. It is noteworthy, however, that an online resource based on Food and Drug Administration and social media information, reports several hemorrhagic and thrombotic events in patients simultaneously taking dabigatran and some commonly used antibiotics such as amoxicillin, cephalosporin, and metronidazole. According to these reports, the administration of antibiotics in patients undergoing therapy with DOACs would seem to require accurate evaluation as to whether dose adjustments (personalized or antibiotic class driven) of the anticoagulant drug may be advisable. This might be facilitated by direct laboratory assessments of their anticoagulant effect ex vivo. PMID:24919144

    Full Text Available Uropathogenic strains from inpatient and outpatient departments were studied from April 1997 to March 1999 for their susceptibility profiles. The various isolates were Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus mirabilis, Acinetobacter baumanii and Enterococcus faecalis. Antibiotic susceptibility pattern of these isolates revealed that for outpatients, first generation cephalosporins, nitrofurantoin, norfloxacin/ciprofloxacin were effective for treatment of urinary tract infection but for inpatients, parenteral therapy with newer aminoglycosides and third generation cephalosporins need to be advocated as the organisms for nosocomial UTI exhibit a high degree of drug resistance. Trimethoprim and sulphamethoxazole combination was not found to be effective for the treatment of urinary tract infections as all the uropathogens from inpatients and outpatients showed high degree of resistance to co-trimoxazole. Culture and sensitivity of the isolates from urine samples should be done as a routine before advocating the therapy.

    Sukumar, S; Roberts, A P; Martin, F E; Adler, C J

    2016-08-01

    Antibiotic resistance is considered one of the greatest threats to global public health. Resistance is often conferred by the presence of antibiotic resistance genes (ARGs), which are readily found in the oral microbiome. In-depth genetic analyses of the oral microbiome through metagenomic techniques reveal a broad distribution of ARGs (including novel ARGs) in individuals not recently exposed to antibiotics, including humans in isolated indigenous populations. This has resulted in a paradigm shift from focusing on the carriage of antibiotic resistance in pathogenic bacteria to a broader concept of an oral resistome, which includes all resistance genes in the microbiome. Metagenomics is beginning to demonstrate the role of the oral resistome and horizontal gene transfer within and between commensals in the absence of selective pressure, such as an antibiotic. At the chairside, metagenomic data reinforce our need to adhere to current antibiotic guidelines to minimize the spread of resistance, as such data reveal the extent of ARGs without exposure to antimicrobials and the ecologic changes created in the oral microbiome by even a single dose of antibiotics. The aim of this review is to discuss the role of metagenomics in the investigation of the oral resistome, including the transmission of antibiotic resistance in the oral microbiome. Future perspectives, including clinical implications of the findings from metagenomic investigations of oral ARGs, are also considered. PMID:27183895

  9. Ready for a world without antibiotics? The Pensières Antibiotic Resistance Call to Action

    Directory of Open Access Journals (Sweden)

    Carlet Jean

    2012-02-01

    Full Text Available Abstract Resistance to antibiotics has increased dramatically over the past few years and has now reached a level that places future patients in real danger. Microorganisms such as Escherichia coli and Klebsiella pneumoniae, which are commensals and pathogens for humans and animals, have become increasingly resistant to third-generation cephalosporins. Moreover, in certain countries, they are also resistant to carbapenems and therefore susceptible only to tigecycline and colistin. Resistance is primarily attributed to the production of beta-lactamase genes located on mobile genetic elements, which facilitate their transfer between different species. In some rare cases, Gram-negative rods are resistant to virtually all known antibiotics. The causes are numerous, but the role of the overuse of antibiotics in both humans and animals is essential, as well as the transmission of these bacteria in both the hospital and the community, notably via the food chain, contaminated hands, and between animals and humans. In addition, there are very few new antibiotics in the pipeline, particularly for Gram-negative bacilli. The situation is slightly better for Gram-positive cocci as some potent and novel antibiotics have been made available in recent years. A strong and coordinated international programme is urgently needed. To meet this challenge, 70 internationally recognized experts met for a two-day meeting in June 2011 in Annecy (France and endorsed a global call to action ("The Pensières Antibiotic Resistance Call to Action". Bundles of measures that must be implemented simultaneously and worldwide are presented in this document. In particular, antibiotics, which represent a treasure for humanity, must be protected and considered as a special class of drugs.

    Antibiotic resistance menaces the population as a dire public health threat and costly social problem. Recent proposals to combat antibiotic resistance focus to a large degree on supply side approaches. Suggestions include tinkering with patent rights so that pharmaceutical companies have greater incentives to discover novel antibiotics as well as to resist overselling their newer drugs already on market. This Article argues that a primarily supply side emphasis unfortunately detracts attention from physicians' important demand side influences. Physicians have a vital and unavoidably necessary role to play in ensuring socially optimal access to antibiotics. Dismayingly, physicians' management of the antibiotic supply has been poor and their defense of population health tepid at best. Acting as a prudent steward of the antibiotic supply often seems to be at odds with a physician's commonly understood fiduciary duties, ethical obligations, and professional norms, all of which traditionally emphasize the individual health paradigm as opposed to population health responsibilities. Meanwhile, physicians face limited incentives for antibiotic conservation from other sources, such as malpractice liability, regulatory standards, and reimbursement systems. While multifaceted efforts are needed to combat antibiotic resistance effectively, physician gatekeeping behavior should become a priority area of focus. This Article considers how health law and policy tools could favorably change the incentives physicians face for antibiotic conservation. A clear lesson from the managed care reform battles of the recent past is that interventions, to have the best chance of success, need to respect physician interest in clinical autonomy and individualized medicine even if, somewhat paradoxically, vigorously promoting population health perspectives. Also, physicians' legal and ethical obligations need to be reconceptualized in the antibiotic context in order to better support

    The evolution and spread of antibiotic-resistant pathogens has become a major threat to public health. Advanced tools are urgently needed to quickly diagnose antibiotic-resistant infections to initiate appropriate treatment. Here we report the development of a highly sensitive flow cytometric method to probe minority population of antibiotic-resistant bacteria via single cell detection. Monoclonal antibody against TEM-1 β-lactamase and Alexa Fluor 488-conjugated secondary antibody were used to selectively label resistant bacteria green, and nucleic acid dye SYTO 62 was used to stain all the bacteria red. A laboratory-built high sensitivity flow cytometer (HSFCM) was applied to simultaneously detect the side scatter and dual-color fluorescence signals of single bacteria. By using E. coli JM109/pUC19 and E. coli JM109 as the model systems for antibiotic-resistant and antibiotic-susceptible bacteria, respectively, as low as 0.1% of antibiotic-resistant bacteria were accurately quantified. By monitoring the dynamic population change of a bacterial culture with the administration of antibiotics, we confirmed that under the antimicrobial pressure, the original low population of antibiotic-resistant bacteria outcompeted susceptible strains and became the dominant population after 5hours of growth. Detection of antibiotic-resistant infection in clinical urine samples was achieved without cultivation, and the bacterial load of susceptible and resistant strains can be faithfully quantified. Overall, the HSFCM-based quantitative method provides a powerful tool for the fundamental studies of antibiotic resistance and holds the potential to provide rapid and precise guidance in clinical therapies.

Material and methods All antibacterial agents were classified as group J, regarding Anatomic-Therapeutic-Chemical Classification. Data on drug utilization were presented in Defined Daily Doses (DDD. Patients who were under observation were all treated with antibiotics. Results In regard to prescribed treatment in the Ear, Nose and Throat Department of the Outpatient Service of the Health Center Novi Sad - Liman, most outpatients were treated with macrolide antibiotics - in 26.21%; combination of penicillin and beta-lactamase inhibitors in 20.83% and pyranosides in 16.12%. At the Ear, Nose and Throat Clinic of the Clinical Center Novi Sad, macrolides and lincosamines were most frequently used - in 20.46%; cephalosporins in 19.87% and penicillins susceptible to beta-lactamase in 18.85%. It is extremely positive and in agreement with current pharmacotherapeutic principles that in both institutions peroral ampicillins have not been prescribed. Aminoglycosides have been prescribed in less than 1% of patients of the Ear, Nose and Throat Department of the Outpatient Service of the Health Center Novi Sad - Liman, whereas they were much more frequently prescribed at the Ear, Nose and Throat Clinic of the Clinical Center Novi Sad - in 11.25%. Although there is a positive postantibiotic effect in regard to these antibiotics and it is recommended to use them once a day, in both examined institutions aminoglycosides were given twice a day. In regard to bacterial identification it was done in 80.76% of patients of the Ear, Nose and Throat Department of the Outpatient Service of the Health Center Novi Sad - Liman, while in the Ear, Nose and Throat Clinic of the Clinical Center

    We provide a representative analysis of antibiotic prescribing, identify factors associated with broad-spectrum antibiotic prescribing and assess the costs associated with antibiotic use in adult outpatients in Greece. Outpatient antibiotic prescriptions for patients older than 19 years between 2010 and 2013 in Greece were extracted from the IMS Health Xponent database. Prescribing rate and total cost for prescribed antibiotics were calculated. Multivariate logistic regression was used to identify factors related to broad-spectrum antibiotic prescribing. More than 20 million antibiotics were prescribed during the study period, an annual rate of 768 prescribed antibiotics per 1,000 adults. Overall, 33.5% of antibiotics were prescribed for acute respiratory tract infections (ARTIs) for which antibiotics are often not indicated. Macrolides (29.9%), cephalosporins (26.9%) and fluoroquinolones (21.0%) were the most commonly prescribed antibiotic classes. The majority (89.0%) of antibiotics were broad-spectrum. Antibiotic expenditures were approximately EUR 185 million during the study period. Factors associated with broad-spectrum prescribing included older patient age, specialty pulmonologists or otorhinolaryngologists, training in eastern Europe, diagnosis of ARTI, acute diagnosis, and first episode of disease. Broad-spectrum antibiotic prescribing for ARTIs is common in adult Greek outpatients and frequently inappropriate. These data indicate the need for initiatives aiming to control antibiotic prescribing. PMID:27390126

    Background: Pediatric Intensive Care Unit (PICU) patients are often prescribed antibiotics with a low threshold in comparison to patients elsewhere. Irrational antibiotics use can lead to rapid emergence of drug resistance, so surveillance of their use is important. Objectives: To evaluate the use of antibiotics in relation to bacteriological findings in PICU of a Tertiary Hospital. Methods: Retrospective review of medical records of all children (age 1 month–16 years) admitted in our closed multidisciplinary-cardiothoracic PICU from January to June 2013 was performed, after approval from Ethical Review Committee. For each antibiotic, indication (prophylactic, empiric, therapeutic) and duration of use were recorded. All diagnoses of infections were recorded according to diagnostic criteria of IPSCC 2005. Results are presented as frequency and percentages and median with inter quartile range using SPSS version 19. Results: All of the total 240 patients admitted in PICU during the study period received antibiotics: 43% (n = 104) prophylactically, 42% (n = 102) empirically, and 15% (n = 15) therapeutically. Median number of antibiotic use per patient in PICU was 3, with range of 1–7. 25% received 1 antibiotic, 23% received 2 antibiotics, 29% received 3 antibiotics, and rest received ≥4 antibiotics. Most commonly used antibiotics were cefazolin, meropenem, vancomycin and ceftriaxone, and most frequently used combination was meropenem and vancomycin. In majority of the cases, (70%) empiric antibiotic combinations were stopped in 72 h. Conclusion: This is the first report of antibiotics use in PICU from our country, which shows that antibiotics are prescribed universally in our PICU. Strategies to assess the need for antibiotic use are needed.

  1. Antibiotics and oral contraceptives.

    Rubin, D F

    1981-04-01

    Dermatologists often prescribe oral tetracycline for the control of acne, primarily, and to a much lesser extent, for the treatment of cutaneous infections. A number of the patients taking tetracycline are also taking birth control pills. A recent article in the British Medical Journal (1980;1:293) indicates that this combination can lead to a failure of the (OC) oral contraceptive. Such failure had been associated with ampicillin as well. It is believed that the mechanism for this was the disturbance in normal gut flora, with consequent effects on bacterial hydrolysis of steroid conjugates. This would interrupt the enterohepatic circulation of contraceptive steroids, resulting in a less than normal concentration of circulating steroids. It was recommended that women taking low-dose OCs take extra precautions against pregnancy during any cycle in which antibiotics are given. In regard to our care of and responsibilities to our patients, and in an era when malpractice suits for all types of reasons are more common, it certainly behooves dermatologists to recognize and be concerned about this potential consequence of prescribing oral antibiotics.

    Full Text Available BACKGROUND: The appropriate use of antibiotics prophylaxis in the prevention and reduction in the incidence of surgical site infection is widespread. This study evaluates the appropriateness of the prescription of antibiotics prophylaxis prior to surgery amongst hospitalized patients in the geographic area of Avellino, Caserta, and Naples (Italy and the factors associated with a poor adherence. METHODS: A sample of 382 patients admitted to 23 surgical wards and undergoing surgery in five hospitals were randomly selected. RESULTS: Perioperative antibiotic prophylaxis was appropriate in 18.1% of cases. The multivariate logistic regression analysis showed that patients with hypoalbuminemia, with a clinical infection, with a wound clean were more likely to receive an appropriate antibiotic prophylaxis. Compared with patients with an American Society of Anesthesiologists (ASA score ≥4, those with a score of 2 were correlated with a 64% reduction in the odds of having an appropriate prophylaxis. The appropriateness of the timing of prophylactic antibiotic administration was observed in 53.4% of the procedures. Multivariate logistic regression model showed that such appropriateness was more frequent in older patients, in those admitted in general surgery wards, in those not having been underwent an endoscopic surgery, in those with a higher length of surgery, and in patients with ASA score 1 when a score ≥4 was chosen as the reference category. The most common antibiotics used inappropriately were ceftazidime, sultamicillin, levofloxacin, and teicoplanin. CONCLUSIONS: Educational interventions are needed to improve perioperative appropriate antibiotic prophylaxis.

    This study evaluated the effect of combining antibiotics with ultrasound and microbubbles (USMB) toward the eradication of biofilms. Pseudomonas aeruginosa PAO1 biofilms were treated with the antibiotics gentamicin sulfate or streptomycin sulfate, or a combination of USMB with the respective antibiotics. Biofilm structure was quantified using confocal laser scanning microscopy with COMSTAT analysis, while activity was measured as whole-biofilm CO2 production in a continuous-flow biofilm model. The combined antibiotic-USMB treatment significantly impacted biofilm biomass, thickness and surface roughness compared to antibiotics alone (p<0.05). USMB exposure caused the formation of craters (5-20μm in diameter) in the biofilms, and when combined with gentamicin, activity was significantly lower, compared to gentamicin, USMB or untreated controls, respectively. Interestingly, the CO2 production rate following combined streptomycin-USMB treatment was higher than after streptomycin alone, but significantly lower than USMB alone and untreated control. These results show strong evidence of a synergistic effect between antibiotics and USMB, although the varied response to different antibiotics emphasize the need to optimize the USMB exposure conditions to maximize this synergism and ultimately transfer this technology into clinical or industrial practice.

    Full Text Available Objective. To study the antimicrobial susceptibility of six vaginal probiotic lactobacilli. Methods. The disc diffusion method in Müeller Hinton, LAPTg and MRS agars by the NCCLS (National Committee for Clinical Laboratory Standards procedure was performed. Due to the absence of a Lactobacillus reference strains, the results were compared to those of Staphylococcus aureus ATCC29213. Minimal Inhibitory Concentration (MIC with 21 different antibiotics in LAPTg agar and broth was also determined. Results. LAPTg and MRS agars are suitable media to study antimicrobial susceptibility of lactobacilli. However, the NCCLS procedure needs to be standardized for this genus. The MICs have shown that all Lactobacillus strains grew at concentrations above 10 μg/mL of chloramphenicol, aztreonam, norfloxacin, ciprofloxacin, ceftazidime, ceftriaxone, streptomycin and kanamycin. Four lactobacilli were sensitive to 1 μg/mL vancomycin and all of them were resistant to 1000 μg/mL of metronidazole. Sensitivity to other antibiotics depended on each particular strain. Conclusions. The NCCLS method needs to be standardized in an appropriate medium to determine the antimicrobial susceptibility of Lactobacillus. Vaginal probiotic lactobacilli do not display uniform susceptibility to antibiotics. Resistance to high concentrations of metronidazole suggests that lactobacilli could be simultaneously used with a bacterial vaginosis treatment to restore the vaginal normal flora.

    Perry, Julie; Waglechner, Nicholas; Wright, Gerard

    2016-01-01

    Antibiotic resistance is a global problem that is reaching crisis levels. The global collection of resistance genes in clinical and environmental samples is the antibiotic "resistome," and is subject to the selective pressure of human activity. The origin of many modern resistance genes in pathogens is likely environmental bacteria, including antibiotic producing organisms that have existed for millennia. Recent work has uncovered resistance in ancient permafrost, isolated caves, and in human specimens preserved for hundreds of years. Together with bioinformatic analyses on modern-day sequences, these studies predict an ancient origin of resistance that long precedes the use of antibiotics in the clinic. Understanding the history of antibiotic resistance is important in predicting its future evolution. PMID:27252395

  4. Energy resources

    International Nuclear Information System (INIS)

    Cuba, like most island nations, lacks a large energy resource base and satisfies most of its energy needs with imported fossil fuels. The evaluation of the availability of domestic energy reserves and resources, as well as their future extraction potential, is a necessary task in an assessment of sustainable energy development. When estimates of potential availability of fossil fuels are carried out, a distinction is made between reserves and resources. In this study, reserves are known quantities that can be extracted with current technology at current prices. Resources are either less certain as to their existence or known to be technically or economically unfeasible or both. In the case of renewables, the concept of resources needs to be modified. Renewable resources are part of a natural flow that can be regenerated in a time frame that is suitable for human activities. For this reason, it is necessary to refer to renewable energy potential rather than resources. Both resources and reserves change as new technologies become available or due to changes in the market. This is another reason to distinguish between resources, reserves and energy potential

  5. Funding Antibiotic Innovation With Vouchers: Recommendations On How To Strengthen A Flawed Incentive Policy.

    A serious need to spur antibiotic innovation has arisen because of the lack of antibiotics to combat certain conditions and the overuse of other antibiotics leading to greater antibiotic resistance. In response to this need, proposals have been made to Congress to fund antibiotic research through a voucher program for new antibiotics, which would delay generic entry for any drug, even potential blockbuster lifesaving generics. We find this proposal to be inefficient, in part because of the mismatch between the private value of the voucher and the public value of the antibiotic innovation. However, vouchers have the political advantage in the United States of being able to raise sufficient amounts of money without annual appropriations from Congress. We propose that if antibiotic vouchers are to be considered, the design should include dollar and time caps to limit their volatility, sufficient advance notice to protect generic manufacturers, and market-based linkages between the value of the voucher and the value of the antibiotic innovation. We also explore a second option: The federal government could auction vouchers to the highest bidders and use the money to create an antibiotics innovation fund. PMID:27140983

    Full Text Available Water scarcity is a global problem, and is particularly acute in certain regions like Africa, the Middle East, as well as the western states of America. A breakdown on water usage revealed that 70% of freshwater supplies are used for agricultural irrigation. The use of reclaimed water as an alternative water source for agricultural irrigation would greatly alleviate the demand on freshwater sources. This paradigm shift is gaining momentum in several water scarce countries like Saudi Arabia. However, microbial problems associated with reclaimed water may hinder the use of reclaimed water for agricultural irrigation. Of particular concern is that the occurrence of antibiotic residues in the reclaimed water can select for antibiotic resistance genes among the microbial community. Antibiotic resistance genes can be associated with mobile genetic elements, which in turn allow a promiscuous transfer of resistance traits from one bacterium to another. Together with the pathogens that are present in the reclaimed water, antibiotic resistant bacteria can potentially exchange mobile genetic elements to create the “perfect microbial storm”. Given the significance of this issue, a deeper understanding of the occurrence of antibiotics in reclaimed water, and their potential influence on the selection of resistant microorganisms would be essential. In this review paper, we collated literature over the past two decades to determine the occurrence of antibiotics in municipal wastewater and livestock manure. We then discuss how these antibiotic resistant bacteria may impose a potential microbial risk to the environment and public health, and the knowledge gaps that would have to be addressed in future studies. Overall, the collation of the literature in wastewater treatment and agriculture serves to frame and identify potential concerns with respect to antibiotics, antibiotic resistant bacteria, and antibiotic resistance genes in reclaimed water.

    As well as the search for new antibiotics, a new resource or strains for the known antibiotics is also important. Microbial symbionts in the gut of termites could be regarded as one of the feasible resource for such purpose. In this study, antibiotic-producing actinomycetes were screened from symbionts of the termite gut. 16SrRNA sequence analysis for the 10 isolates revealed that they belong to actinomycetes such as Streptomyces sp., Kitasatospora sp., and Mycobacterium sp. A culture broth from one of the isolate, namely strain CA1, belonging to the genera Streptomyces exhibited antagonistic activity against actinomycetes (Micrococcus spp.), gram-positive bacteria (Bacillus spp.), and yeast (Candida spp.). The structures of 2 compounds isolated from the culture broth of the strain CA1 were identified as those of actinomycin X2 and its analog, D. This study is the first to report that some symbionts of the termite gut are antibiotic-producing actinomycetes, and suggest that the termite gut is a feasible resource for bioprospecting.

    Full Text Available ABSTRACTMonitoring programs have traditionally monitored legacy contaminants but are shifting focus to Contaminants of Emerging Concern (CECs. CECs present many challenges for monitoring and assessment, because measurement methods don't always exist nor have toxicological studies been fully conducted to place results in proper context. Also some CECs affect metabolic pathways to produce adverse outcomes that are not assessed through traditional toxicological evaluations. Antibiotics are CECs that pose significant environmental risks including development of both toxic effects at high doses and antibiotic resistance at doses well below the Minimum Inhibitory Concentration (MIC which kill bacteria and have been found in nearly half of all sites monitored in the US. Antimicrobial resistance has generally been attributed to the use of antibiotics in medicine for humans and livestock as well as aquaculture operations. The objective of this study was to assess the extent and magnitude of antibiotics in the environment and estimate their potential hazards in the environment. Antibiotics concentrations were measured in a number of monitoring studies which included Waste Water Treatment Plants (WWTP effluent, surface waters, sediments and biota. A number of studies reported levels of Antibiotic Resistant Microbes (ARM in surface waters and some studies found specific ARM genes (e.g. the blaM-1 gene in E. coli which may pose additional environmental risk. High levels of this gene were found to survive WWTP disinfection and accumulated in sediment at levels 100-1000 times higher than in the sewerage effluent, posing potential risks for gene transfer to other bacteria.in aquatic and marine ecosystems. Antibiotic risk assessment approaches were developed based on the use of MICs and MIC Ratios [High (Antibiotic Resistant/Low (Antibiotic Sensitive MIC] for each antibiotic indicating the range of bacterial adaptability to each antibiotic to help define the No

    Full Text Available Postoperative surgical site infections are a major source of illness.  Infection results in longer hospital stay and higher costs.  Uses of preoperative antibiotics have been standardized and are being used routinely in most clinical surgeries and include controversial areas like breast surgery and herniorraphy. Objective of the study is to find out the benefit of prophylactic use of antibiotics in the management of herniorraphy.This project was carried out in a multispeciality tertiary care teaching hospital from 1st-30th April in 2002. Group 1 patients were treated prophylactically half an hour before surgery with single dose of I.V. antibiotics (injection.  Ampicillin 1gm + injection.  Gentamicin 80mg. Group 2 patients were treated post surgery with capsule. Ampicillin 500mg 4 times a day for 7 days and injection. Gentamicin twice a day for first 4 days. In case of group 1 patients only one out of 20 patients (5% was infected.  Whereas in-group 2 patients 5 out of 20 patients (25% were infected. The cost of prophylactic antibiotic treatment was Rs. 25.56 per patient.  The postoperative antibiotic treatment cost was Rs. 220.4 per patient.  That means postoperative treatment is around 8.62 times costlier than prophylactic treatment.             From this study it is evident that prophylactic (preoperative treatment is better than postoperative treatment with antibiotics.

    Science.gov (United States)

    Scholz, R. W.; Wellmer, F.-W.

    2015-01-01

    Several recent papers predict a scarcity of phosphate reserves in the near future. The paper by Edixhoven et al. (2014), for instance, expresses the doubts about whether the upward estimate of reserves by the IFDC (2010) and the USGS (2010) provide an accurate, reliable, and comparable picture, as they are based on reports that do not clearly differentiate between phosphate ore and phosphate products (i.e., marketable phosphate rock concentrate). Further the indistinct use of the terms reserves and resources is criticized. Edixhoven et al. ask for a differentiated inventory of world phosphate reserves including "guidelines which determine the appropriate drill hole distances." The claim that humanity is on the safe side with respect to future phosphate is supply is doubted as the validity of the IFDC's upgrading of the Moroccan data to 50 Gt phosphate is questioned. The present paper identifies and discusses basic conceptual errors of the paper by Edixhoven et al. and related papers that predict a short or mid-term phosphorus scarcity. These include the non-acknowledgment of the dynamic nature of reserves (which depends on price, technology, and innovation for exploiting low-grade deposits, etc.), the mixing of finiteness and staticness of the ultimate recoverable resources (i.e., phosphorus that may be mined economically in the long-term future), the improper use of the Hubbert analysis (which, e.g., simply uses the USGS estimates of reserves as a substitute of an estimate of ultimate recoverable resources) and the geostatistical naive/unprofessional demand for fixed drilling plans to assess reserves. We reconstruct the IFDC and USGS estimates and conclude that there is no evidence for considering the 50 Gt phosphate concentrate as an unreasonable estimate for Moroccan reserves. However, the partial mixing of different units (e.g., phosphate ore and phosphate concentrate or marketable product) in the USGS data may be avoided by improving the data base and using

    Full Text Available Introduction: It is increasingly important to prioritize the most cost-effective HIV interventions. We sought to summarize the evidence on which types of interventions provide the best value for money in regions with concentrated HIV epidemics. Methods: We conducted a systematic review of peer-reviewed and grey literature reporting measurements of cost-effectiveness or cost-benefit for HIV/AIDS interventions in Asia and Eastern Europe. We also collated HIV/AIDS spending assessment data from case-study countries in the region. Results: We identified 91 studies for inclusion, 47 of which were from peer-reviewed journals. Generally, in concentrated settings, prevention of mother-to-child transmission programmes and prevention programmes targeting people who inject drugs and sex workers had lower incremental cost-effectiveness ratios than programmes aimed at the general population. The few studies evaluating programmes targeting men who have sex with men indicate moderate cost-effectiveness. Collation of prevention programme spending data from 12 countries in the region (none of which had generalized epidemics indicated that resources for the general population/non-targeted was greater than 30% for eight countries and greater than 50% for five countries. Conclusions: There is a misalignment between national spending on HIV/AIDS responses and the most affected populations across the region. In concentrated epidemics, scarce funding should be directed more towards most-at-risk populations. Reaching consensus on general principles of cost-effectiveness of programmes by epidemic settings is difficult due to inconsistent evaluation approaches. Adopting a standard costing, impact evaluation, benefits calculation, analysis and reporting framework would enable cross comparisons and improve HIV resource prioritization and allocation.

  2. Early Antibiotic Treatment in Acute Pancreatitis: More News

    Directory of Open Access Journals (Sweden)

    Jan J De Waele

    2006-07-01

    Full Text Available Early antibiotic treatment still remains a therapeutic challenge in the clinical management of acute pancreatitis and several papers have been published in this field [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14]. In particular, the antibiotic of choice in preventing the infection of pancreatic necrosis seems to be imipenem [4, 9, 10, 11, 13]. Subsequently, Manes et al. [15] have reported that meropenem, an antibiotic of the same family as imipenem having considerable stability in the presence of renal dehydropeptidase-I and enhanced activity against gram-negative bacteria including Pseudomonas aeruginosa, has an efficacy similar to imipenem in terms of the incidence of pancreatic infection and extrapancreatic infections. We have previously emphasized that further studies should be carried out to specifically decide on the optimal doses of meropenem in patients with acute pancreatitis and that there is a need for studies which answer the following questions. What should the timing of early antibiotic treatment be?. What are the resistant strains selected by meropenem?. Which are the nosocomial infections and fungal superinfections resulting from this new treatment? [16, 17]. These questions are still open and the study from Manes et al. is welcome to attempt to answer some of the aforementioned questions [18]. In this study, the authors compared antibiotic prophylaxis with early antibiotic treatment started after the demonstration of pancreatic necrosis. They studied 215 consecutive patients with acute pancreatitis who were randomized to either Group A (n=108, who started antibiotic therapy (meropenem 500 mg tid at admission, or Group B (n=107, who received antibiotics after computed tomography showed necrosis. C-reactive protein was determined in all patients within 48 hours from the onset of symptoms and computed tomography was performed in both groups after at least 48 h of hospitalization; the clinical course of disease was also compared

    A biofilm is a structured consortium of bacteria embedded in a self-produced polymer matrix consisting of polysaccharide, protein and DNA. Bacterial biofilms cause chronic infections because they show increased tolerance to antibiotics and disinfectant chemicals as well as resisting phagocytosis...... to antibiotics. Biofilm growth is associated with an increased level of mutations as well as with quorum-sensing-regulated mechanisms. Conventional resistance mechanisms such as chromosomal beta-lactamase, upregulated efflux pumps and mutations in antibiotic target molecules in bacteria also contribute...... to the survival of biofilms. Biofilms can be prevented by early aggressive antibiotic prophylaxis or therapy and they can be treated by chronic suppressive therapy. A promising strategy may be the use of enzymes that can dissolve the biofilm matrix (e.g. DNase and alginate lyase) as well as quorum...

  4. [Methodology of Screening New Antibiotics: Present Status and Prospects].

    Trenin, A S

    2015-01-01

    Due to extensive distribution of pathogen resistance to available pharmaceuticals and serious problems in the treatment of various infections and tumor diseases, the necessity of new antibiotics is urgent. The basic methodological approaches to chemical synthesis of antibiotics and screening of new antibiotics among natural products, mainly among microbial secondary metabolites, are considered in the review. Since the natural compounds are very much diverse, screening of such substances gives a good opportunity to discover antibiotics of various chemical structure and mechanism of action. Such an approach followed by chemical or biological transformation, is capable of providing the health care with new effective pharmaceuticals. The review is mainly concentrated on screening of natural products and methodological problems, such as: isolation of microbial producers from the habitats, cultivation of microorganisms producing appropriate substances, isolation and chemical characterization of microbial metabolites, identification of the biological activity of the metabolites. The main attention is paid to the problems of microbial secondary metabolism and design of new models for screening biologically active compounds. The last achievements in the field of antibiotics and most perspective approaches to future investigations are discussed. The main methodological approach to isolation and cultivation of the producers remains actual and needs constant improvement. The increase of the screening efficiency can be achieved by more rapid chemical identification of antibiotics and design of new screening models based on the biological activity detection.

    Aminoglycoside antibiotics are used in the treatment of infections caused by Gram-negative bacteria, and are often dispensed only in severe cases due to their adverse side effects. Patients undergoing treatment with these antibiotics are therefore commonly subjected to therapeutic drug monitoring (TDM) to ensure a safe and effective personalised dosage. The ability to detect these antibiotics in a rapid and sensitive manner in human fluids is therefore of the utmost importance in order to provide effective monitoring of these drugs, which could potentially allow for a more widespread use of this class of antibiotics. Herein, we report on the detection of various aminoglycosides, by exploiting their ability to aggregate gold nanoparticles. The number and position of the amino groups of aminoglycoside antibiotics controlled the aggregation process. We investigated the complementary techniques of surface enhanced Raman spectroscopy (SERS) and localized surface plasmon resonance (LSPR) for dual detection of these aminoglycoside antibiotics and performed an in-depth study of the feasibility of carrying out TDM of tobramycin using a platform amenable to high throughput analysis. Herein, we also demonstrate dual detection of tobramycin using both LSPR and SERS in a single platform and within the clinically relevant concentration range needed for TDM of this particular aminoglycoside. Additionally we provide evidence that tobramycin can be detected in spiked human serum using only functionalised nanoparticles and SERS analysis. PMID:27412506

  6. Rapid determination of antibiotic resistance in E. coli using dielectrophoresis

    International Nuclear Information System (INIS)

    In recent years, infections due to antibiotic-resistant strains of bacteria such as methillicin-resistant Staphylococcus aureus and ciprofloxacin-resistant Escherichia coli are on the rise, and with them the demand for rapid antibiotic testing is also rising. Conventional tests, such as disc diffusion testing, require a primary sample to be tested in the presence of a number of antibiotics to verify which antibiotics suppress growth, which take approximately 24 h to complete and potentially place the patient at severe risk. In this paper we describe the use of dielectrophoresis as a rapid marker of cell death, by detecting changes in the electrophysiology of the cell caused by the administration of an antibiotic. In contrast to other markers, the electrophysiology of the cell changes rapidly during cell death allowing live cells to be distinguished from dead (or dying) cells without the need for culturing. Using polymyxin B as an example antibiotic, our studies indicate that significant changes in cell characteristics can be observed as soon as 1 h passes after isolating a culture from nutrient broth

  7. Antibiotic administration and the development of obesity in children.

    2016-03-01

    Antibiotics are the most common prescription drugs administered at the paediatric age, however their administration can cause unwanted problems. Among these issues, antibiotic-induced gut microbiota dysbiosis has appeared as an emerging issue and has been associated with obesity. This problem is particularly relevant in children because they are frequently treated with antibiotics. Early development of obesity increases the risk of adult obesity, which is associated with the emergence of very severe clinical problems. Dysbiosis induced in the first periods of life can have the most relevant practical consequences because a decrease in the number of microbes and their substitution with other microbes dramatically modifies the development of the immune system as well as glucose and lipid metabolism. Unfortunately, not all of the mechanisms that could explain the relationship between gut microbiota modification and the development of obesity have been defined. Consequently, no definitive therapeutic approach has been elucidated. Probiotics and prebiotics could play a role in treating microbial dysbiosis because the addition of specific bacterial strains has been associated with normal weight and has been demonstrated to be useful in clinical conditions other than obesity that are caused by microbiota disruption. Considering that antibiotics are commonly prescribed and that obesity is increasing in paediatric patients, further studies specifically designed to evaluate how to disrupt the relationship between antibiotics and dysbiosis are urgently needed. Presently, paediatricians have to consider dysbiosis to be a new and serious reason for the judicious use of antibiotics in clinical practice. PMID:26895606

    2014-06-01

    Full Text Available Background and Objective: The excessive use of broad-spectrum antibiotics will lead to drug resistance of microorganism and specially nosocomial organisms. Because of high incidence of antibiotic resistance in hospitals, we aimed to study antibiotic resistance to gram negative bacteria. Material and Methods: This cross-sectional study was conducted on the data of biological samples (2006-2008, with positive culture result. Using antibiogram, microbial resistance to isolated microorganism was determined, and after culturing the samples, bacteria were identified by using differential media and antiserum. Then, antibiotic resistance was performed by disk diffusion. Results: The most common gram-negative microorganism obtained from all cultures was E.coli with the lowest drug resistance to Nitrofurantoin. Conclusion: Based on the results, antimicrobial resistance pattern is not the same in different places and furthermore it is ever changing. Therefore, further research is needed to be done to have an accurate pattern of antibiotic resistance to provide effective treatment regimens.

Materials and Methods: An online survey was sent to 208 members of the Canadian Association of Paediatric Surgeons (CAPS and the Association of Paediatric Surgeons of Nigeria (APSON. Results: The response rate was 76.8% with 127 complete surveys (APSON 34, CAPS 97. Only 29.5% of APSON surgeons had frozen section available for diagnosis of HD. They were more likely to choose full thickness rectal biopsy (APSON 70.6% vs. CAPS 9.4%, P < 0.05 and do an initial colostomy for HD (APSON 23.5% vs. CAPS 0%, P < 0.05. Experience with trans-anal pull-through for HD was similar in both groups (APSON 76.5%, CAPS 66.7%. CAPS members practising in the United States were more likely to perform a one-stage pull-through for HD during the initial hospitalization (USA 65.4% vs. Canada 28.3%, P < 0.05. The frequency of colostomy in females with vestibular fistula varied widely independent of geography. APSON surgeons were less likely to have enterostomal therapists and patient education resources. Conclusions: Local resources which vary by geographic location affect the management of HD and ARM including colostomy. Collaboration between CAPS and APSON members could address resource and educational needs to improve patient care.

    The literature on the manufacture, separation and purification, and clinical uses of antibiotics was reviewed, and a bibliography of the pertinent material was completed. Five antimicrobial drugs, penicillin V and G, (and amoxicillin with clavulanic acid), Cephalexin (a cephalosporin), tetracycline and oxytetracycline, Bacitracin (topical), and sulfonamide (chemically produced) were identified for emergency production. Plants that manufacture antibiotics in the continental United States, Mexico, and Puerto Rico have been identified along with potential alternate sites such as those where SCP, enzyme, and fermentation ethanol are produced. Detailed process flow sheets and process descriptions have been derived from the literature and documented. This investigation revealed that a typical antibiotic-manufacturing facility is composed of two main sections: (1) a highly specialized, but generic, fermentation unit and (2) a multistep, complex separation and purification unit which is specific to a particular antibiotic product. The fermentation section requires specialized equipment for operation in a sterile environment which is not usually available in other industries. The emergency production of antibiotics under austere conditions will be feasible only if a substantial reduction in the complexity and degree of separation and purity normally required can be realized. Detailed instructions were developed to assist state and federal officials who would be directing the resumption of antibiotic production after a nuclear attack. 182 refs., 54 figs., 26 tabs.

  15. A natural resource: what happens when oil interests conflict with the needs of a northern caribou herd and the people who depend on it?

    International Nuclear Information System (INIS)

    Although the Alaska National Interest Lands Conservation Act (ANILCA) established a wildlife refuge to protect the calving grounds of the Porcupine caribou, striking oil in Prudhoe Bay led to the construction of a pipeline, which even in decline delivers one million barrels of oil a day to the Port of Valdez. Given the money generated by the oil industry, it is not surprising that most Alaska legislators favour extraction of the nature reserve's petroleum resources. So far, legislation by the President, supported by a group of senators, managed to keep the drilling rigs out of the nursery of the Porcupine caribou. In Canada, too, aboriginal leaders and environmentalist groups have worked hard to ensure that the federal government continues to oppose the leasing of the coastal plain to developers. Development would negatively affect the Porcupine caribou herd, the traditional way of life of aboriginal communities, and the ecological integrity of Ivvavik National Park. Although the fate of the calving ground will ultimately be decided in Washington, the health of the Porcupine caribou herd is a true cross-border issue. So far, the two governments have managed to stave off development and to assert that such a relatively pristine and intact biosphere should remain intact. However, the pressure by the oil industry giants is relentless, and requires constant vigilance

  1. Antibiotic use during the intracoelomic implantation of electronic tags into fish

    Science.gov (United States)

    Mulcahy, D.M.

    2011-01-01

    The use of antibiotics, in particular, the use of a single dose of antibiotics during electronic tag implantation is of unproven value, and carries with it the potential for the development of antibiotic resistance in bacteria and the alteration of the immune response of the fish. Antibiotic use during electronic tag implantation must conform to relevant drug laws and regulations in the country where work is being done, including the requirements for withdrawal times before human consumption is a possibility. Currently, the choice of antibiotics (most often tetracycline or oxytetracycline) and the use of a single dose of the drug are decisions made without knowledge of the basic need for antibiotic usage and of the bacteria involved in infections that occur following electronic tag implantation. Correct perioperative use of an antibiotic is to apply the drug to the animal before surgery begins, to assure serum and tissue levels of the drug are adequate before the incision is made. However, the most common perioperative application of antibiotics during implantation of an electronic tag is to delay the administration of the drug, injecting it into the coelom after the electronic tag is inserted, just prior to closure of the incision. There is little empirical evidence that the present application of antibiotics in fish being implanted with electronic tags is of value. Improvements should first be made to surgical techniques, especially the use of aseptic techniques and sterilized instruments and electronic tags, before resorting to antibiotics. ?? 2010 Springer Science+Business Media B.V.(outside the USA).

    Strong laboratory services and systems are critical for delivering timely and quality health services that are vital to reduce patient attrition in the HIV treatment and prevention cascade. However, challenges exist in ensuring effective laboratory health systems strengthening and linkages. In particular, linkages and referrals between laboratory testing and other services need to be considered in the context of an integrated health system that includes prevention, treatment, and strategic information. Key components of laboratory health systems that are essential for effective linkages include an adequate workforce, appropriate point-of-care (POC) technology, available financing, supply chain management systems, and quality systems improvement, including accreditation. In this review, we highlight weaknesses of and gaps between laboratory testing and other program services. We propose a model for strengthening these systems to ensure effective linkages of laboratory services for improved access and retention in care of HIV/AIDS patients, particularly in low- and middle-income countries.

    Intimate partner violence (IPV) is as prevalent in lesbian, gay, bisexual, and transgender (LGBT) relationships as it is in heterosexual ones; however, the issues, needs, and challenges associated with assisting or advocating on behalf of LGBT persons are poorly understood. Using community-based participatory approaches, we conducted a brief survey of professionals (e.g., shelter staff, domestic violence prevention and intervention programs, law enforcement) affiliated with one or more domestic violence prevention and/or intervention networks in Los Angeles, California. The sample, which included professionals (N = 54) from diverse programs/agencies, was obtained using purposive and snowball sampling. Participants self-administered a 33-item, online questionnaire. Analyses primarily involved descriptive statistics (frequencies, proportions). Most respondents had little or no training in LGBT IPV; nevertheless, nearly 50% of them reported having assisted LGBTs "sometimes" or "often" in the past year. Nearly all (92%) reported that their agencies/programs lack staff with dedicated responsibilities to LGBT IPV. The most frequent requests for assistance respondents reported receiving from LGBTs were for counseling, safe housing, legal assistance, and assistance navigating the medical system. The findings suggest that staff believe their agencies/programs inadequately address LGBT IPV but that many of the inadequacies (e.g., lack of staff training on LGBT IPV) are remediable.

    2005-06-01

    Allergic reactions to antibiotics are more common in cystic fibrosis (CF) than in the general population. This in part is due to the improving survival in adults with CF and the increased use of high dose intravenous antibiotics. While some are immediate anaphylaxis type (IgE mediated) reactions, the majority are late onset and may have non-specific features such as rash and fever. Piperacillin has consistently been found to have the highest rate of reported reactions (30-50%). There is a low risk of cross reactions between penicillins and other non-beta-lactam classes of antibiotics in penicillin skin prick positive patients. Carbapenems should only be used with extreme caution in patients with positive skin prick tests to penicillin. However, aztreonam can be used safely in patients who are penicillin allergic with positive skin prick reactions. The aminoglycosides are a relatively uncommon cause of allergic reactions, but patients who react to one member of the family may cross react with other aminoglycosides. Desensitisation relies on the incremental introduction of small quantities of the allergen and has been used for penicillins, ceftazidime, tobramycin and ciprofloxacin and must be repeated before each course. Personalized cards should be regularly updated for patients who develop allergic reactions. Written instructions on the emergency treatment of allergic reactions should be provided to patients self-administering intravenous antibiotics at home. Further research is required to identify risk factors and predictors for antibiotic allergy. PMID:15923254

    2016-02-01

    Despite the growing threat of antimicrobial resistance, pharmaceutical and biotechnology firms are reluctant to develop novel antibiotics because of a host of market failures. This problem is complicated by public health goals that demand antibiotic conservation and equitable patient access. Thus, an innovative incentive strategy is needed to encourage sustainable investment in antibiotics. This systematic review consolidates, classifies and critically assesses a total of 47 proposed incentives. Given the large number of possible strategies, a decision framework is presented to assist with the selection of incentives. This framework focuses on addressing market failures that result in limited investment, public health priorities regarding antibiotic stewardship and patient access, and implementation constraints and operational realities. The flexible nature of this framework allows policy makers to tailor an antibiotic incentive package that suits a country's health system structure and needs. PMID:26464014

    The commercial antibiotics tetracycline (3), minocycline (4), chlortetracycline (5), oxytetracycline (6), and doxycycline (7) were biotransformed by a marine-derived fungus Paecilomyces sp. to yield seco-cyclines A-H (9-14, 18 and 19) and hemi-cyclines A-E (20-24). Structures were assigned by detailed spectroscopic analysis, and in the case of 10 X-ray crystallography. Parallel mechanisms account for substrate-product specificity, where 3-5 yield seco-cyclines and 6 and 7 yield hemi-cyclines. The susceptibility of 3-7 to fungal biotransformation is indicative of an unexpected potential for tetracycline "degradation" (i.e., antibiotic resistance) in fungal genomes. Significantly, the fungal-derived tetracycline-like viridicatumtoxins are resistant to fungal biotransformation, providing chemical insights that could inform the development of new tetracycline antibiotics resistant to enzymatic degradation.

    1992-12-01

    A dental source of infection remains the most common identifiable risk factor in infective endocarditis and this may be particularly important in patients at 'high risk'. We therefore performed a questionnaire survey of dental practitioners to assess acceptance of The British Society of Antimicrobial Chemotherapy (BSAC) recommendations, especially with regards to selection of dental procedures for antibiotic prophylaxis. The results showed that the dental practitioners surveyed treated the 'high risk' patient group differently by extending the range of dental procedures covered by antibiotics but the BSAC only recommend that they be treated differently by hospital treatment and/or parenteral antibiotics. This must be an area of concern and deserves further attention, especially with regards to the need for wider publicity and the range of dental procedures that should be covered in the 'high risk' group where morbidity and mortality from infective endocarditis are higher.

    2009-11-01

    Eugenol, the principal chemical component of clove oil from Eugenia aromatica has been long known for its analgesic, local anesthetic, anti-inflammatory, and antibacterial effects. The interaction of the eugenol with ten different hydrophobic and hydrophilic antibiotics was studied against five different Gram negative bacteria. The MIC of the combination was found to decrease by a factor of 5-1000 with respect to their individual MIC. This synergy is because of the membrane damaging nature of eugenol, where 1mM of its concentration is able to damage nearly 50% of the bacterial membrane. Eugenol was also able to enhance the activities of lysozyme, Triton X-100 and SDS in damaging the bacterial cell membrane. The hydrophilic antibiotics such as vancomycin and beta-lactam antibiotics which have a marginal activity on these gram negative bacteria exhibit an enhanced antibacterial activity when pretreated with eugenol. Reduced usage of antibiotics could be employed as a treatment strategy to slow down the onset of antibiotic resistance as well as decrease its toxicity. Experiments performed with human blood cells indicated that the concentration of eugenol used for the combination studies were below its cytotoxic values. Pharmacodynamic studies of the combinations need to be performed to decide on the effective dosage. PMID:19540744

    Full Text Available Inappropriate initial antibiotics for pneumonia infection are usually linked to extended intensive care unit stay and are associated with an increased risk of mortality. This study evaluates the impact of inappropriate initial antibiotics on the length of intensive care unit stay, risk of mortality and the co-predictors that influences these outcomes. This retrospective study was conducted in an intensive care unit of a teaching hospital. The types of pneumonia investigated were hospital-acquired pneumonia and ventilator-associated pneumonia. Three different time points were defined as the initiation of appropriate antibiotics at 24 h, between 24 to 48 h and at more than 48 h after obtaining a culture. Patients had either hospital-acquired pneumonia (59.1% or ventilator-associated pneumonia (40.9%. The length of intensive care unit stay ranged from 1 to 52 days (mean; 9.78±10.02 days. Patients who received appropriate antibiotic agent at 24 h had a significantly shorter length of intensive care unit stay (5.62 d, P<0.001. The co-predictors that contributed to an extended intensive care unit stay were the time of availability of susceptibility results and concomitant diseases, namely cancer and sepsis. The only predictor of intensive care unit death was cancer. The results support the need for early appropriate initial antibiotic therapy in hospital-acquired pneumonia and ventilator-associated pneumonia infections.

    2016-02-01

    Over the last decade, numerous evidences have contributed to establish a link between the natural and human-impacted environments and the growing public health threat that is the antimicrobial resistance. In the environment, in particular in areas subjected to strong anthropogenic pressures, water plays a major role on the transformation and transport of contaminants including antibiotic residues, antibiotic-resistant bacteria, and antibiotic resistance genes. Therefore, the urban water cycle, comprising water abstraction, disinfection, and distribution for human consumption, and the collection, treatment, and delivery of wastewater to the environment, is a particularly interesting loop to track the fate of antibiotic resistance in the environment and to assess the risks of its transmission back to humans. In this article, the relevance of different transepts of the urban water cycle on the potential enrichment and spread of antibiotic resistance is reviewed. According to this analysis, some gaps of knowledge, research needs, and control measures are suggested. The critical rationale behind the measures suggested and the desirable involvement of some key action players is also discussed. PMID:26649735

The aim of this study was to investigate the rationale of antibiotic prescribing among Jordanian clinicians who practice oral implantology. Findings The target sample for the study was the 250 Jordan Dental Implant Group members. A five page questionnaire contained 41 questions, both closed and open questions were used to collect data. Statistical analysis was performed using SPSS Windows 16.0 (SPSS Inc., Chicago, IL, USA. Descriptive statistics were generated. The response rate was (70.4% 176/250. Mean age was 37.2 yrs, 49.4% always prescribe antibiotics mainly oral amoxicillin and amoxicillin with clavulinic acid. Antibiotics prescribing increased with flap raising, multiple implants and sinus or bone augmentation. Patient medical condition, periodontitis and oral hygiene were the most important clinical factors in antibiotic prescribing, non-clinical factors were; reading scientific materials, courses and lectures, knowledge gained during training, and the effectiveness and previous experience with the drug. Conclusions Wide variations in antibiotics types, routes, dose and duration of administration were found. Recommendations on antibiotic prescribing are needed to prevent antibiotic overprescribing and misuse.

    Acinetobacter calcoaceticus–baumannii complex is a common cause of hospital-acquired infections (HAIs) globally, remarkable for its high rate of antibiotic resistance, including to carbapenems. There are few data on the resistance of A. baumannii in Vietnam, which are essential for developing evidence-based treatment guidelines for HAIs. Antibiotic susceptibility testing was conducted by VITEK®2, and pulsed-field gel electrophoresis (PFGE) was performed on 66 clinical A. baumannii complex isolates recovered during 2009 at the National Hospital of Tropical Diseases (NHTD), a referral hospital in Hanoi, Vietnam. Basic demographic and clinical data were collected and analysed using descriptive statistics. Most isolates came from lower respiratory tract specimens (59; 89.4%) from intensive care unit (ICU) patients [64/65 (98.5%) with available data] who had been admitted to NHTD for ≥2 days [42/46 (91.3%) with available data]. More than 90% of the isolates were resistant to the tested β-lactamase/β-lactamase inhibitors, cephalosporins, carbapenems, fluoroquinolones and trimethoprim/sulfamethoxazole. Moreover, 25.4% (16/63) were resistant to all tested β-lactams, quinolones and aminoglycosides. All isolates remained sensitive to colistin and 58.7% were susceptible to tigecycline. Of the 66 isolates, 49 could be classified into eight PFGE types (A–H). Every PFGE type, except D, had cluster(s) of three or more isolates with a temporal relationship. In conclusion, these data suggest a significant rise in A. baumannii antibiotic resistance in Vietnam. Clustering within PFGE types supports cross-transmission of A. baumannii within the ICU at NHTD. Increased research and resources in optimising treatment, infection control and antibiotic stewardship are needed. PMID:25540720

    Although historically, antibiotic resistance has occurred naturally in environmental bacteria, many questions remain regarding the specifics of how humans and animals contribute to the development and spread of antibiotic resistance in agroecosystems. Additional research is necessary to completely understand the potential risks to human, animal, and ecological health in systems altered by antibiotic-resistance-related contamination. At present, analyzing and interpreting the effects of human and animal inputs on antibiotic resistance in agroecosystems is difficult, since standard research terminology and protocols do not exist for studying background and baseline levels of resistance in the environment. To improve the state of science in antibiotic-resistance-related research in agroecosystems, researchers are encouraged to incorporate baseline data within the study system and background data from outside the study system to normalize the study data and determine the potential impact of antibiotic-resistance-related determinants on a specific agroecosystem. Therefore, the aims of this review were to (i) present standard definitions for commonly used terms in environmental antibiotic resistance research and (ii) illustrate the need for research standards (normalization) within and between studies of antibiotic resistance in agroecosystems. To foster synergy among antibiotic resistance researchers, a new surveillance and decision-making tool is proposed to assist researchers in determining the most relevant and important antibiotic-resistance-related targets to focus on in their given agroecosystems. Incorporation of these components within antibiotic-resistance-related studies should allow for a more comprehensive and accurate picture of the current and future states of antibiotic resistance in the environment.

    Infection is a major problem in burn care and especially when it is due to bacteria with hospital-acquired multi-resistance to antibiotics. Moreover, when these bacteria are Gram-negative organisms, the most effective molecules are 20 years old and there is little hope of any new product available even in the distant future. Therefore, it is obvious that currently available antibiotics should not be misused. With this aim in mind, the following review was conducted by a group of experts from the French Society for Burn Injuries (SFETB). It examined key points addressing the management of antibiotics for burn patients: when to use or not, time of onset, bactericidia, combination, adaptation, de-escalation, treatment duration and regimen based on pharmacokinetic and pharmacodynamic characteristics of these compounds. The authors also considered antibioprophylaxis and some other key points such as: infection diagnosis criteria, bacterial inoculae and local treatment. French guidelines for the use of antibiotics in burn patients have been designed up from this work. PMID:20510518

    2007-05-01

    Full Text Available Abstract Background Inappropriate antibiotic use promotes resistance. Antibiotics are generally not indicated for upper respiratory infections (URIs. Our objectives were to describe patterns of URI treatment and to identify patient and provider factors associated with antibiotic use for URIs. Methods This study was a cross-sectional analysis of medical and pharmacy claims data from the Pennsylvania Medicaid fee-for-service program database. We identified Pennsylvania Medicaid recipients with a URI office visit over a one-year period. Our outcome variable was antibiotic use within seven days after the URI visit. Study variables included URI type and presence of concurrent acute illnesses and chronic conditions. We considered the associations of each study variable with antibiotic use in a logistic regression model, stratifying by age group and adjusting for confounders. Results Among 69,936 recipients with URI, 35,786 (51.2% received an antibiotic. In all age groups, acute sinusitis, chronic sinusitis, otitis, URI type and season were associated with antibiotic use. Except for the oldest group, physician specialty and streptococcal pharyngitis were associated with antibiotic use. History of chronic conditions was not associated with antibiotic use in any age group. In all age groups, concurrent acute illnesses and history of chronic conditions had only had fair to poor ability to distinguish patients who received an antibiotic from patients who did not. Conclusion Antibiotic prevalence for URIs was high, indicating that potentially inappropriate antibiotic utilization is occurring. Our data suggest that demographic and clinical factors are associated with antibiotic use, but additional reasons remain unexplained. Insight regarding reasons for antibiotic prescribing is needed to develop interventions to address the growing problem of antibiotic resistance.

  16. The global problem of antibiotic resistance.

    2010-01-01

    Amid the recent attention justly focused on the potential problem of microbial sources for weapons of bioterrorism, it is also apparent that human pathogens frequently isolated from infections in patients from community and hospital sources have been growing more resistant to commonly used antibiotics. Much of the growth of multiple-drug-resistant (MDR) bacterial pathogens can be contributed to the overuse of broad-spectrum antimicrobial products. However, an equally troubling and often overlooked component of the problem involves the elegant ways in which pathogenic bacteria continually evolve complex genetic systems for acquiring and regulating an endless array of antibiotic-resistance mechanisms. Efforts to develop new antimicrobials have over the past two decades been woefully behind the rapid evolution of resistance genes developing among both gram-positive and gram-negative pathogens. Several new agents that are best suited for use in the hospital environment have been developed to combat staphylococci resistant to beta-lactam antimicrobials following acquisition of the mecA gene. However, the dramatic spread in the US of the now common community strain of Staphylococcus aureus USA300 has shifted the therapeutic need for new antibiotics useful against MRSA to the community. As the pharmaceutical industry focused on discovering new agents for use against MRSA, hospitals in many parts of the world have seen the emergence of gram-negative pathogens such as Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae that are clinically resistant to almost all available antimicrobials. Such MDR isolates usually contain multiple-resistance determinants, including loss of outer membrane porins via gene inactivation by chromosomally encoded insertion sequences, up-regulation of inate efflux pumps, as well as acquisition of drug-inactivating enzymes whose genes are encoded on self-transmissible plasmids, integrons, and complex transposable elements

    Protein synthesis is a major target within the bacterial cell for antibiotics. Investigations into ribosome-targeting antibiotics have provided much needed functional and structural insight into their mechanism of action. However, the increasing prevalence of multi-drug-resistant bacteria has limited the utility of our current arsenal of clinically relevant antibiotics, highlighting the need for the development of new classes. Recent structural studies have characterized a number of antibiotics discovered decades ago that have unique chemical scaffolds and/or utilize novel modes of action to interact with the ribosome and inhibit translation. Additionally, structures of eukaryotic cytoplasmic and mitochondrial ribosomes have provided further structural insight into the basis for specificity and toxicity of antibiotics. Together with our increased understanding of bacterial resistance mechanisms, revisiting our treasure trove of "forgotten" antibiotics could pave the way for the next generation of antimicrobial agents.

    Large numbers of livestock and poultry feces are continuously applied into soils in intensive vegetable cultivation areas, and then some veterinary antibiotics are persistent existed in soils and cause health risk. For the spatial heterogeneity of antibiotic residues, developing a suitable technique to interpolate soil antibiotic residues is still a challenge. In this study, we developed an effective interpolator, high accuracy surface modeling (HASM) combined vegetable types, to predict the spatial patterns of soil antibiotics, using 100 surface soil samples collected from an intensive vegetable cultivation area located in east of China, and the fluoroquinolones (FQs), including ciprofloxacin (CFX), enrofloxacin (EFX) and norfloxacin (NFX), were analyzed as the target antibiotics. The results show that vegetable type is an effective factor to be combined to improve the interpolator performance. HASM achieves less mean absolute errors (MAEs) and root mean square errors (RMSEs) for total FQs (NFX+CFX+EFX), NFX, CFX and EFX than kriging with external drift (KED), stratified kriging (StK), ordinary kriging (OK) and inverse distance weighting (IDW). The MAE of HASM for FQs is 55.1 μg/kg, and the MAEs of KED, StK, OK and IDW are 99.0 μg/kg, 102.8 μg/kg, 106.3 μg/kg and 108.7 μg/kg, respectively. Further, RMSE simulated by HASM for FQs (CFX, EFX and NFX) are 106.2 μg/kg (88.6 μg/kg, 20.4 μg/kg and 39.2 μg/kg), and less 30% (27%, 22% and 36%), 33% (27%, 27% and 43%), 38% (34%, 23% and 41%) and 42% (32%, 35% and 51%) than the ones by KED, StK, OK and IDW, respectively. HASM also provides better maps with more details and more consistent maximum and minimum values of soil antibiotics compared with the measured data. The better performance can be concluded that HASM takes the vegetable type information as global approximate information, and takes local sampling data as its optimum control constraints.

    Full Text Available Antibiotic surveillance initiatives are limited in resource-constrained settings. In the present study, a quantitative comparison of antibiotic use rates for suspected infections in 2 hospitals in India was performed using the "focus of infection" approach to identify targets for quality improvement in antibiotic prescription patterns in hospitalized patients.This observational study was carried out in one teaching and one nonteaching hospital. All the patients with suspected bacterial etiology were included. Data on the prescribed antibiotics and the focus of infection were prospectively collected using a structured questionnaire. Each diagnosis was further reviewed and confirmed by an independent consultant. The prescribed antibiotics were coded according to the World Health Organization Anatomic Therapeutic Classification (ATC index with the defined daily dose (DDD methodology. Focus-specific DDDs were calculated per hundred patient days (DDD/HPD.A total of 6026 patients were included from 72 participating physicians out of available 75 physicians. Overall antibiotic prescribing was higher by 5 percentage points in the teaching hospital (95% than in the nonteaching hospital (90%. Quinolones (ciprofloxacin constituting 86% of DDD/HPD were the highest prescribed class in the teaching hospital, and third-generation cephalosporins (with ceftriaxone and ceftriaxone/sulbactam constituting 40% and 28% of the DDD/HPD, respectively, in the nonteaching hospital. The targets identified for improvement were the following: longer than recommended duration of prophylaxis and lack of distinction between prophylaxis and therapy among surgical patients; irrational antibiotic prescribing in gastroenteritis; overuse of quinolones and lack of use of penicillin in pneumonia; overuse of quinolones and lack of use of doxycycline and macrolides in genital infections; and overreliance on antibiotics for treating skin and soft tissue infections.Providing a

    Antibiotics are essential for control of bacterial diseases of plants, especially fire blight of pear and apple and bacterial spot of peach. Streptomycin is used in several countries; the use of oxytetracycline, oxolinic acid and gentamicin is limited to only a few countries. Springtime antibiotic sprays suppress pathogen growth on flowers and leaf surfaces before infection; after infection, antibiotics are ineffective. Antibiotics are applied when disease risk is high, and consequently the majority of orchards are not treated annually. In 2009 in the United States, 16,465 kg (active ingredient) was applied to orchards, which is 0.12% of the total antibiotics used in animal agriculture. Antibiotics are active on plants for less than a week, and significant residues have not been found on harvested fruit. Antibiotics have been indispensable for crop protection in the United States for more than 50 years without reports of adverse effects on human health or persistent impacts on the environment.

    Antibiotic resistant bacteria (ARB) and antibiotic resistance genes (ARG) in the aquatic environment have become an emerging contaminant issue, which has implications for human and ecological health. This review begins with an introduction to the occurrence of ARB and ARG in different environmental systems such as natural environments and drinking water resources. For example, ARG or ARB with resistance to ciprofloxacin, sulfamethoxazole, trimethoprim, quinolone, vancomycin, or tetracycline (e.g., tet(A), tet(B), tet(C), tet(G), tet(O), tet(M), tet(W), sul I, and sul II) have been detected in the environment. The development of resistance may be intrinsic, may be acquired through spontaneous mutations (de novo), or may occur due to horizontal gene transfer from donor bacteria, phages, or free DNA to recipient bacteria. An overview is also provided of the current knowledge regarding inactivation of ARB and ARG, and the mechanism of the effects of different disinfection processes in water and wastewater (chlorination, UV irradiation, Fenton reaction, ozonation, and photocatalytic oxidation). The effects of constructed wetlands and nanotechnology on ARB and ARG are also summarized. PMID:26775188

    2014-04-01

    Full Text Available Degrading antibiotics discharged in the livestock manure in a well-controlled bioprocess contributes to a more sustainable and environment-friendly livestock breeding. Although most antibiotics remain stable during manure storage, anaerobic digestion can degrade and remove them to various extents depending on the concentration and class of antibiotic, bioreactor operating conditions, type of feedstock and inoculum sources. Generally, antibiotics are degraded during composting > anaerobic digestion > manure storage > soil. Manure matrix variation influences extraction, quantification, and degradation of antibiotics, but it has not been well investigated. Fractioning of manure-laden antibiotics into liquid and solid phases and its effects on their anaerobic degradation and the contribution of abiotic (physical and chemical versus biotic degradation mechanisms need to be quantified for various manures, antibiotics types, reactor designs and temperature of operations. More research is required to determine the kinetics of antibiotics’ metabolites degradation during anaerobic digestion. Further investigations are required to assess the degradation of antibiotics during psychrophilic anaerobic digestion.

  15. Frequency of wound infection in non-perforated appendicitis with use of single dose perforative antibiotics

    International Nuclear Information System (INIS)

    Antibiotics are used both pre and post-operatively in acute appendicitis for preventing wound infection. It has been observed that the routine use of post-operative antibiotics is not necessary in cases of non-perforated appendicitis as only prophylactic antibiotics are sufficient to prevent wound infection. The aim of this study was to see the frequency of wound infection in non-perforated appendicitis with single dose preoperative antibiotics only. Method: This observational study was conducted at the Department of Surgery, Ayub Medical College, Abbottabad from May to November 2014. A total of 121 patients with non-perforated appendicitis were included in the study. Only single dose preoperative antibiotics were used. The patients were followed for wound infection till 8th post-operative day. Results: 121 patients, 56(46.28%) male and 65(53.72%) female were included in the study. The mean age of patients was 27.41 ± 7.12 years with an age range of 18 to 45 years. In the entire series, 7(5.78%) patients developed wound infection. The infection was minor which settled with conservative therapy. Prophylactic antibiotics were found efficacious in 114(94.21%) patients. There was no significant association between wound infection and age and gender. Conclusion: Single dose preoperative antibiotics were found effective in controlling post-operative wound infection without the need of extending the antibiotics to post-operative period in cases of non-perforated appendicitis.

    Full Text Available Aims and Objectives: It has been observed that various microorganisms are acquiring resistance to most of the available potent antibiotics; hence, there is a need for every hospital to follow the use of antibiotics according to antibiotic sensitivity pattern in that particular hospital or geographical area. It has been reported that Enterobacteriaceae group of microorganisms are increasingly acquiring resistance to many antibiotics and this resistance varies geographically. As there is a short of recent data with respect to Indian hospital, this particular study was designed with the aim of establishing sensitivity pattern of Enterobacteriaceae group of microorganisms to various antibiotics. Materials and Methods: Data of antibiotic sensitivity from December 2010 to April 2011 of different Enterobacteriaceae was taken from the Department of Microbiology, Govt. Medical College, Surat. Sensitivity of different Enterobacteriaceae was shown as using descriptive statistics. Results: E. coli (55.6% and Klebsiella (31.2% were the most frequent bacteria isolated. Enterobacteriaceae were very less sensitive to amoxicillin + clavulanic acid (13.7%, chloramphenicol (7.6%, cefoperazone (14.4%, cefixime (15.7%, and cefuroxime (17.6. Sensitivity to aztreonam was 32.7%. Sensitivity to carbapenem group of drugs included in this study, i.e., meropenem was 69.8%. Highest sensitivity was shown for ceftazidime (74.1%. E. coli is more sensitive to meropenem as compared with Klebsiella. Conclusion: Sensitivity of Enterobacteriaceae group of microorganisms to known antibiotics is decreasing. Decreased sensitivity to carbapenem group of antibiotics is a matter of concern.

    Antibiotics play a pivotal role in the management of infectious disease in humans, companion animals, livestock, and aquaculture operations at a global scale. Antibiotics are produced, consumed, and released into the environment at an unprecedented scale causing concern that the presence of antibiotic residues may adversely impact aquatic and terrestrial ecosystems. Here we critically review the ecotoxicological assessment of antibiotics as related to environmental risk assessment (ERA). We initially discuss the need for more specific protection goals based on the ecosystem service concept, and suggest that the ERA of antibiotics, through the application of a mode of toxic action approach, should make more use of ecotoxicological endpoints targeting microorganisms (especially bacteria) and microbial communities. Key ecosystem services provided by microorganisms and associated ecosystem service-providing units (e.g. taxa or functional groups) are identified. Approaches currently available for elucidating ecotoxicological effects on microorganisms are reviewed in detail and we conclude that microbial community-based tests should be used to complement single-species tests to offer more targeted protection of key ecosystem services. Specifically, we propose that ecotoxicological tests should not only assess microbial community function, but also microbial diversity (‘species’ richness) and antibiotic susceptibility. Promising areas for future basic and applied research of relevance to ERA are highlighted throughout the text. In this regard, the most fundamental knowledge gaps probably relate to our rudimentary understanding of the ecological roles of antibiotics in nature and possible adverse effects of environmental pollution with subinhibitory levels of antibiotics.

    Despite the life-saving ability of antibiotics and their importance as a key enabler of all of modern health care, their effectiveness is now threatened by a rising tide of resistance. Unfortunately, the antibiotic pipeline does not match health needs because of challenges in discovery and development, as well as the poor economics of antibiotics. Discovery and development are being addressed by a range of public-private partnerships; however, correcting the poor economics of antibiotics will need an overhaul of the present business model on a worldwide scale. Discussions are now converging on delinking reward from antibiotic sales through prizes, milestone payments, or insurance-like models in which innovation is rewarded with a fixed series of payments of a predictable size. Rewarding all drugs with the same payments could create perverse incentives to produce drugs that provide the least possible innovation. Thus, we propose a payment model using a graded array of benchmarked rewards designed to encourage the development of antibiotics with the greatest societal value, together with appropriate worldwide access to antibiotics to maximise human health.

    Antimicrobial resistance and hospital infections have increased alarmingly in India. Antibiotic stewardship and hospital infection control are two broad strategies which have been employed globally to contain the problems of resistance and infections. For this to succeed, it is important to bring on board the various stakeholders in hospitals, especially the clinical pharmacologists. The discipline of clinical pharmacology needs to be involved in themes such as antimicrobial resistance and ho...

    Benchmarks for judicious use of antimicrobials are needed. Metrics such as defined daily doses (DDDs) and days of therapy (DOTs) quantify antimicrobial consumption. However, benchmarking with these metrics is complicated by interhospital variability. Thus, it is important for each hospital to monitor its own temporal consumption trends. Time series analyses allow trends to be detected; however, many of these methods are complex. We present simple regressive methods and caveats in using them to define potential antibiotic over- and underutilizations. PMID:27001807

    Purpose of review Rifaximin is gaining attention for its potential activity in a multitude of gastrointestinal diseases. We review the unique pharmaceutical properties of this antibiotic and the published evidence in the literature regarding the use of rifaximin for different gastrointestinal disorders. Recent findings Rifaximin is a gastrointestinal-selective antibiotic with a broad spectrum of antimicrobial activity, an excellent safety profile, minimal drug interactions, and negligible impact on the intestinal microbiome. Rifaximin is currently approved in the United States for the treatment of travelers’ diarrhea caused by noninvasive diarrheagenic Escherichia coli and is approved in more than 30 other countries for a variety of gastrointestinal disorders. Considerable research with this medication has been conducted for the treatment and prevention of travelers’ diarrhea, the treatment of portal systemic encephalopathy, Clostridium difficile infection, small bowel intestinal overgrowth, irritable bowel syndrome, inflammatory bowel disease, pouchitis, and colonic diverticular disease. Summary Rifaximin is effective for the treatment of travelers’ diarrhea and can be considered as the treatment of choice for uncomplicated travelers’ diarrhea. When invasive travelers’ diarrhea pathogens are suspected, an alternative antibiotic should be administered. Rifaximin appears promising as a chemoprophylaxis for travelers’ diarrhea and as a treatment of portal systemic encephalopathy. This antibiotic may be effective for other gastrointestinal diseases, but more well-designed clinical studies are needed to confirm its efficacy for these off-label indications. Future studies will determine whether the development of significant bacterial resistance will limit rifaximin use. PMID:19881343

    2005-09-01

    Full Text Available Background: Urinary tract infection is a common bacterial disease in children which may cause chronic renal failure and hypertention. Many reports suggest that the rate of antibiotic resistance to infectious organisms is increasing. Therefore periodic surveillance of resistance rates is needed to ensure that appropriate recommendations can be made for better management & preventing of late sequelae. Methods In this cross sectional descriptive study we investigate the results of urinalysis, urine culture and antibiotic sensitivity of the isolated organisms in the urine of 1556 children aged under 10 years in Mashhad city between April 2001 and June 2002. Described parameters are age, sex, incidence of significant bacteriuria, leucocyturia, causative bacterial agents, and antibiotic sensitivity pattern. Findings: The most common age group in both sexes was infantile period. Median age was 20.3 months in boys and 47.5 months in girls. E.coli, klebsiella and proteus were the causative organisms in 87.3%. They were sensitive to cefotaxime, cefixime, cephalotin, amikacin, ciprofloxacin, nitrofurantoin and gentamicin in more than 96% while resistant to trimetoprim-sultamethoxazol in about 75%. Conclusion: We recommend, with regard to continuous changing in causative microorganisms isolated from patients with urinary tract infection and antibiotic sensitivity pattern, as a guideline for physicians, to determine bacterial sensitivity in populations yearly.

    The unprecedented rise of life-threatening antibiotic resistance (AR), combined with the unparalleled advances in DNA sequencing of genomes and metagenomes, has pushed the need for in silico detection of the resistance potential of clinical and environmental metagenomic samples through the quantification of AR genes (i.e., genes conferring antibiotic resistance). Therefore, determining an optimal methodology to quantitatively and accurately assess AR genes in a given environment is pivotal. Here, we optimized and improved existing AR detection methodologies from metagenomic datasets to properly consider AR-generating mutations in antibiotic target genes. Through comparative metagenomic analysis of previously published AR gene abundance in three publicly available metagenomes, we illustrate how mutation-generated resistance genes are either falsely assigned or neglected, which alters the detection and quantitation of the antibiotic resistome. In addition, we inspected factors influencing the outcome of AR gene quantification using metagenome simulation experiments, and identified that genome size, AR gene length, total number of metagenomics reads and selected sequencing platforms had pronounced effects on the level of detected AR. In conclusion, our proposed improvements in the current methodologies for accurate AR detection and resistome assessment show reliable results when tested on real and simulated metagenomic datasets.

    Xuelian Zhang

    Full Text Available This study investigated the occurrence of 12 veterinary antibiotics (VAs and the susceptibility of Escherichia coli (E. coli in a rural water system that was affected by livestock production in northern China. Each of the surveyed sites was determined with at least eight antibiotics with maximum concentration of up to 450 ng L(-1. The use of VAs in livestock farming probably was a primary source of antibiotics in the rivers. Increasing total antibiotics were measured from up- to mid- and downstream in the two tributaries. Eighty-eight percent of the 218 E. coli isolates that were derived from the study area exhibited, in total, 48 resistance profiles against the eight examined drugs. Significant correlations were found among the resistance rates of sulfamethoxazole-trimethoprim, chloromycetin and ampicillin as well as between tetracycline and chlortetracycline, suggesting a possible cross-selection for resistance among these drugs. The E. coli resistance frequency also increased from up- to midstream in the three rivers. E. coli isolates from different water systems showed varying drug numbers of resistance. No clear relationship was observed in the antibiotic resistance frequency with corresponding antibiotic concentration, indicating that the antibiotic resistance for E. coli in the aquatic environment might be affected by factors besides antibiotics. High numbers of resistant E. coli were also isolated from the conserved reservoir. These results suggest that rural surface water may become a large pool of VAs and resistant bacteria. This study contributes to current information on VAs and resistant bacteria contamination in aquatic environments particularly in areas under intensive agriculture. Moreover, this study indicates an urgent need to monitor the use of VAs in animal production, and to control the release of animal-originated antibiotics into the environment.

    Skin and soft tissue infections (SSTIs) are growing in prevalence in both the outpatient and inpatient settings and are some of the most common diseases seen by dermatologists, who are often the first point of care for these patients. Microbial resistance to antibiotics continues to rise as more virulent strains evolve, and strains predominantly found in the hospital setting are now being seen in the community. Therefore, innovative approaches to combat this trend are needed. Glutathione (GSH) is a well-described and established antioxidant. It participates in detoxification of xenobiotics, regulation of cellular growth, modulation of immune response, and maintenance of the thiol status of proteins and cellular cysteine levels. GSH is also known to have a regulatory effect on immune cells and even inherent antibacterial properties have been reported. To this end, the value of GSH as an antibiotic was evaluated by growing methicillin resistant S. aureus, E. coli, K. pneumoniae and P. aeruginosa strains isolated from human skin and soft tissue infection in the presence of GSH. At a physiologic concentration of 10 mM, GSH had no effect on bacterial growth. At concentrations above 50 mM, which created acidic conditions (pH < 4), bacterial growth was completely inhibited. When adjusted to physiologic pH, GSH exhibited a bacteriostatic effect in a concentration-dependent manner. Additionally, the cytotoxicity of GSH was evaluated in a murine cell line. GSH was relatively non-toxic to murine macrophages, even at the highest concentration tested (160 mM). These results suggest the potential utility of GSH for the prevention and/or as adjunctive treatment of infection, most significantly in disease states associated with GSH deficiency. PMID:24196336

    Respiratory lung infections due to multidrug-resistant (MDR) superbugs are on a global upsurge and have very grim clinical outcomes. Their MDR profile makes therapeutic options extremely limited. Although a highly toxic antibiotic, colistin, is favored today as a "last-line" therapeutic against these hard-to-treat MDR pathogens, it is fast losing its effectiveness. This work therefore seeks to identify and tailor-make useful combination regimens (that are potentially rotatable and synergistic) as attractive alternative strategies to address the rising rates of drug resistance. Three potentially rotatable ternary dry powder inhaler constructs (each involving colistin and 2 other different-classed antibiotics chosen from rifampicin, meropenem, and tigecycline) were identified (with distinct complementary killing mechanisms), coformulated via spray drying, evaluated on their aerosol performance using a Next-Generation Impactor and tested for their efficacies against a number of MDR pathogens. The powder particles were of respirable size (d50, 3.1 ± 0.3 μm-3.4 ± 0.1 μm) and predominantly crumpled in morphology. When dispersed via a model dry powder inhaler (Aerolizer(®)) at 60 L/min, the powders showed concomitant in vitro deposition with fine particle fractions of ∼53%-70%. All formulations were successfully tested in the laboratory to be highly effective against the MDR pathogens. In addition, a favorable synergistic interaction was detected across all 3 formulations when tested against MDR Pseudomonas aeruginosa. PMID:27019964

  11. No apparent costs for facultative antibiotic production by the soil bacterium Pseudomonas fluorescens Pf0-1.

    Directory of Open Access Journals (Sweden)

    Paolina Garbeva

    Full Text Available BACKGROUND: Many soil-inhabiting bacteria are known to produce secondary metabolites that can suppress microorganisms competing for the same resources. The production of antimicrobial compounds is expected to incur fitness costs for the producing bacteria. Such costs form the basis for models on the co-existence of antibiotic-producing and non-antibiotic producing strains. However, so far studies quantifying the costs of antibiotic production by bacteria are scarce. The current study reports on possible costs, for antibiotic production by Pseudomonas fluorescens Pf0-1, a soil bacterium that is induced to produce a broad-spectrum antibiotic when it is confronted with non-related bacterial competitors or supernatants of their cultures. METHODOLOGY AND PRINCIPAL FINDINGS: We measured the possible cost of antibiotic production for Pseudomonas fluorescens Pf0-1 by monitoring changes in growth rate with and without induction of antibiotic production by supernatant of a bacterial competitor, namely Pedobacter sp.. Experiments were performed in liquid as well as on semi-solid media under nutrient-limited conditions that are expected to most clearly reveal fitness costs. Our results did not reveal any significant costs for production of antibiotics by Pseudomonas fluorescens Pf0-1. Comparison of growth rates of the antibiotic-producing wild-type cells with those of non-antibiotic producing mutants did not reveal costs of antibiotic production either. SIGNIFICANCE: Based on our findings we propose that the facultative production of antibiotics might not be selected to mitigate metabolic costs, but instead might be advantageous because it limits the risk of competitors evolving resistance, or even the risk of competitors feeding on the compounds produced.

The aim behind undertaking this investigation was to study the prevalence antibiotics self-medication among university students in Benghazi city. Methods: A questionnaire-based cross-sectional, survey was conducted at both Libyan International Medical University and Benghazi University. A total of 665 copies of questionnaires was distributed. A total of 363 forms were completed and returned (response rate 55%. Remaining responses were either with no antibiotics use history within the past 1 year or were provided incomplete. Results: Among the respondents, 45% were males and 55% females. Males practiced self-medication more compared to females. Approximately, 43% and 46% from medical and nonmedical students, respectively, were antibiotics self-medicated. A total of 153 students (42% out of total respondents administered antibiotics for symptoms related to respiratory problems, among which 74 students (48% took antibiotics based on doctor′s prescription. Among the respondents, 94 students (27% who had antibiotics, were covered under medical insurance, and 19 (29% of the medically insured students had antibiotics without doctor′s prescription. About 14% of students did not complete their antibiotics course. Of these, 57% were medical students, and 43% were nonmedical students. The rate of self-medication among higher classes was more as compared to lower classes. About 58% of students overdosed the antibiotic, while 15% had antibiotics for <3 days, for treatment of ailments such as acne, toothache, diarrhea, earache, and tonsillitis. About 75% of students purchased the antibiotics in consultation with a pharmacist. Conclusion: Self-medication is a frequent problem among university students in Benghazi city. There is a need for an immediate intervention to address this malpractice among both students and medical practitioners.

    Full Text Available BACKGROUND: Inappropriate prescription of antibiotics may contribute towards higher levels antimicrobial resistance. A key intervention for improving appropriate antibiotic prescription is surveillance of prescription. This paper presents the results of a longitudinal surveillance of broad-spectrum antibiotic prescription in 5 public-sector hospitals in Singapore from 2006 to 2010. METHODOLOGY/PRINCIPAL FINDINGS: Quarterly antibiotic prescription data were obtained and converted to defined daily doses (DDDs per 1,000 inpatient-days. The presence of significant trends in antibiotic prescription over time for both individual and combined hospitals was tested by regression analysis and corrected for autocorrelation between time-points. Excluding fluoroquinolones, there was a significant increase in prescription of all monitored antibiotics from an average of 233.12 defined daily doses (DDD/1,000 inpatient-days in 2006 to 254.38 DDD/1,000 inpatient-days in 2010 (Coefficient = 1.13, 95%CI: 0.16-2.09, p = 0.025. Increasing utilization of carbapenems, piperacillin/tazobactam, and Gram-positive agents were seen in the majority of the hospitals, while cephalosporins were less prescribed over time. The combined expenditure for 5 hospitals increased from USD9.9 million in 2006 to USD16.7 million in 2010. CONCLUSIONS/SIGNIFICANCE: The rate of prescription of broad-spectrum antibiotics in Singaporean hospitals is much higher compared to those of European hospitals. This may be due to high rates of antimicrobial resistance. The increase in expenditure on monitored antibiotics over the past 5 years outstripped the actual increase in DDD/1,000 inpatient-days of antibiotics prescribed. Longitudinal surveillance of antibiotic prescription on a hospital and countrywide level is important for detecting trends for formulating interventions or policies. Further research is needed to understand the causes for the various prescription trends and to act on these where

    Bassetti, Matteo; Welte, Tobias; Wunderink, Richard G

    2016-01-01

    Beta-lactam antibiotics form the backbone of treatment for Gram-negative pneumonia in mechanically ventilated patients in the intensive care unit. However, this beta-lactam antibiotic backbone is increasingly under pressure from emerging resistance across all geographical regions, and health-care professionals in many countries are rapidly running out of effective treatment options. Even in regions that currently have only low levels of resistance, the effects of globalization are likely to increase local pressures on the beta-lactam antibiotic backbone in the near future. Therefore, clinicians are increasingly faced with a difficult balancing act: the need to prescribe adequate and appropriate antibiotic therapy while reducing the emergence of resistance and the overuse of antibiotics. In this review, we explore the burden of Gram-negative pneumonia in the critical care setting and the pressure that antibiotic resistance places on current empiric therapy regimens (and the beta-lactam antibiotic backbone) in this patient population. New treatment approaches, such as systemic and inhaled antibiotic alternatives, are on the horizon and are likely to help tackle the rising levels of beta-lactam antibiotic resistance. In the meantime, it is imperative that the beta-lactam antibiotic backbone of currently available antibiotics be supported through stringent antibiotic stewardship programs. PMID:26821535

    Seven mesocosm-scale constructed wetlands (CWs), differing in their design characteristics, were set up in the open air to assess their efficiency to remove antibiotics from urban raw wastewater. A conventional wastewater treatment plant (WWTP) was simultaneously monitored. The experiment took place in autumn. An analytical methodology including HPLC-MS/MS was developed to measure antibiotic concentrations in the soluble water fraction, in the suspended solids fraction and in the WWTP sludge. Considering the soluble water fraction, the only easily eliminated antibiotics in the WWTP were doxycycline (61±38%) and sulfamethoxazole (60±26%). All the studied types of CWs were efficient for the removal of sulfamethoxazole (59±30-87±41%), as found in the WWTP, and, in addition, they removed trimethoprim (65±21-96±29%). The elimination of other antibiotics in CWs was limited by the specific system-configuration: amoxicillin (45±15%) was only eliminated by a free-water (FW) subsurface flow (SSF) CW planted with Typha angustifolia; doxycycline was removed in FW systems planted with T. angustifolia (65±34-75±40%), in a Phragmites australis-floating macrophytes system (62±31%) and in conventional horizontal SSF-systems (71±39%); clarithromycin was partially eliminated by an unplanted FW-SSF system (50±18%); erythromycin could only be removed by a P. australis-horizontal SSF system (64±30%); and ampicillin was eliminated by a T. angustifolia-floating macrophytes system (29±4%). Lincomycin was not removed by any of the systems (WWTP or CWs). The presence or absence of plants, the vegetal species (T. angustifolia or P. australis), the flow type and the CW design characteristics regulated the specific removal mechanisms. Therefore, CWs are not an overall solution to remove antibiotics from urban wastewater during cold seasons. However, more studies are needed to assess their ability in warmer periods and to determine the behaviour of full-scale systems. PMID:21356542

    Full Text Available Methicillin resistant Staphylococcus aureus (MRSA infection is a global concern nowadays. Due to its multi-drug resistant nature, treatment with conventional antibiotics does not assure desired clinical outcomes. Therefore, there is a need to find new compounds and/or alternative methods to get arsenal against the pathogen. Combination therapies using conventional antibiotics and phytochemicals fulfill both requirements. In this study, the efficacy of different phytochemicals in combination with selected antibiotics was tested against 12 strains of S. aureus (ATCC MRSA 43300, ATCC methicillin sensitive S. aureus or MSSA 29213 and 10 MRSA clinical strains collected from National University Hospital, Singapore. Out of the six phytochemicals used, tannic acid was synergistic with fusidic acid, minocycline, cefotaxime and rifampicin against most of strains tested and additive with ofloxacin and vancomycin. Quercetin showed synergism with minocycline, fusidic acid and rifampicin against most of the strains. Gallic acid ethyl ester showed additivity against all strains in combination with all antibiotics under investigation except with vancomycin where it showed indifference effect. Eugenol, menthone and caffeic acid showed indifference results against all strains in combination with all antibiotics. Interestingly, no antagonism was observed within these interactions. Based on the fractional inhibitory concentration indices, synergistic pairs were further examined by time-kill assays to confirm the accuracy and killing rate of the combinations over time. The two methods concurred with each other with 92% accuracy and the combinatory pairs were effective throughout the 24 hours of assay. The study suggests a possible incorporation of effective phytochemicals in combination therapies for MRSA infections.

    The world is facing an ever-increasing problem with antibiotic resistant bacteria and we are rapidly heading for a post-antibiotic era. There is an urgent need to investigate alterative treatment options while there are still a few antibiotics left. Bacteriophages are viruses that specifically target bacteria. Before the development of antibiotics, some efforts were made to use bacteriophages as a treatment option, but most of this research stopped soon after the discovery of antibiotics. There are two different replication options which bacteriophages employ. These are the lytic and lysogenic life cycles. Both these life cycles have potential as treatment options. There are various advantages and disadvantages to the use of bacteriophages as treatment options. The main advantage is the specificity of bacteriophages and treatments can be designed to specifically target pathogenic bacteria while not negatively affecting the normal microbiota. There are various advantages to this. However, the high level of specificity also creates potential problems, the main being the requirement of highly specific diagnostic procedures. Another potential problem with phage therapy includes the development of immunity and limitations with the registration of phage therapy options. The latter is driving research toward the expression of phage genes which break the bacterial cell wall, which could then be used as a treatment option. Various aspects of phage therapy have been investigated in studies undertaken by our research group. We have investigated specificity of phages to various avian pathogenic E. coli isolates. Furthermore, the exciting NanoSAM technology has been employed to investigate bacteriophage replication and aspects of this will be discussed. PMID:24619620

    In the field of antibiotic therapy, particularly the methods of economic evaluation hold one's attention within the wide range of health economics' applications. Several tools allow a comparison of the outcomes of alternative strategies and thereby guide choices to the most appropriate solutions. After a brief recall of the methods classically used to evaluate health care strategy, the authors stress the importance and difficulty of fixing and applying a correct and satisfactory procedure for evaluation. An evaluation example of antibiotic therapy allows to illustrate the application of the principles confronting a field in which competition is intense and economic stakes stay large--a fact which naturally yields to seek after objective decision making criteria. The health care policies drawn by public authorities as well as the marketing strategies of the health sector trade are partly based on such evaluations. If these techniques are not intended for the practitioner in the first place, they should not be indifferent to him since they influence health authorities and thereby indirectly affect the therapeutic freedom of the physician.

    Full Text Available Background: The antibacterial properties of a compound are the result of its molecular structure. To establish the structural and electronic characteristics makes possible to understand the mechanisms of its action and becomes paramount for the rational design new drugs. Objective: To model some of the molecular properties of betalactamic antibiotics and inhibitors of the betalactamases and to relate them with their pharmacological actions. Method: The molecular structures were optimized with PM3• semiempiric calculus. The structure of the betalactamic ring in the different compounds was compared. The molecular properties were calculated according to the Density Functional Theory at a B3LYP/6-31G(d level. The density of the atomic charges and the frontier orbitals were analyzed. Results There are variations in the calculated properties that make possible to define two groups of compounds: one for the monobactams and the inhibitors of the betalactamases, with less planarity in the ring and less reactivity and another one with the penicillins, cephalosporins and carbapenems, planer, more structurally stable and reactive. Conclusions: The modelled molecular properties of the betalactamic antibiotics and inhibitors of the betalactamases show agreement with its pharmacological action.

  12. Noninferior Antibiotics: When Is "Not Bad" "Good Enough"?

    Science.gov (United States)

    DiNubile, Mark J

    2016-09-01

    Novel treatment options are urgently needed for patients with serious multidrug-resistant infections seen increasingly in routine everyday clinical practice, both in the hospital and nursing home as well as in the clinic and office setting. Unfortunately, the problem is no longer confined to chronically ill, repeatedly hospitalized patients. This essay explores the role of noninferiorly studies in addressing the pressing need for new antimicrobial agents to combat the emerging "superbugs", calling attention to the nuances of interpreting their sometimes less-than-straightforward results. The overriding aim is not to find better antibiotics for routinely treatable infections but to identify safe and efficacious treatment options where none presently exist. PMID:27382597

    Full Text Available Attiya Siddiqi, Sanjay SethiDivision of Pulmonary, Critical Care and Sleep Medicine, Department of Medicine, Veterans Affairs Western New York Health Care System and University of Buffalo, State University of New York, Buffalo, New York, USAAbstract: Our understanding of the etiology, pathogenesis and consequences of acute exacerbations of chronic obstructive pulmonary disease (COPD has increased substantially in the last decade. Several new lines of evidence demonstrate that bacterial isolation from sputum during acute exacerbation in many instances reflects a cause-effect relationship. Placebo-controlled antibiotic trials in exacerbations of COPD demonstrate significant clinical benefits of antibiotic treatment in moderate and severe episodes. However, in the multitude of antibiotic comparison trials, the choice of antibiotics does not appear to affect the clinical outcome, which can be explained by several methodological limitations of these trials. Recently, comparison trials with nontraditional end-points have shown differences among antibiotics in the treatment of exacerbations of COPD. Observational studies that have examined clinical outcome of exacerbations have repeatedly demonstrated certain clinical characteristics to be associated with treatment failure or early relapse. Optimal antibiotic selection for exacerbations has therefore incorporated quantifying the risk for a poor outcome of the exacerbation and choosing antibiotics differently for low risk and high risk patients, reserving the broader spectrum drugs for the high risk patients. Though improved outcomes in exacerbations with antibiotic choice based on such risk stratification has not yet been demonstrated in prospective controlled trials, this approach takes into account concerns of disease heterogeneity, antibiotic resistance and judicious antibiotic use in exacerbations.Keywords: COPD, exacerbation, bronchitis, antibiotics

    Full Text Available Abstract Background For decades, there is an unresolved debate about adequate prescription of antibiotics for patients suffering from exacerbations of chronic obstructive pulmonary disease (COPD. The aim of this systematic review was to analyse randomised controlled trials investigating the clinical benefit of antibiotics for COPD exacerbations. Methods We conducted a systematic review of randomised, placebo-controlled trials assessing the effects of antibiotics on clinically relevant outcomes in patients with an exacerbation. We searched bibliographic databases, scrutinized reference lists and conference proceedings and asked the pharmaceutical industry for unpublished data. We used fixed-effects models to pool results. The primary outcome was treatment failure of COPD exacerbation treatment. Results We included 13 trials (1557 patients of moderate to good quality. For the effects of antibiotics on treatment failure there was much heterogeneity across all trials (I2 = 82%. Meta-regression revealed severity of exacerbation as significant explanation for this heterogeneity (p = 0.016: Antibiotics did not reduce treatment failures in outpatients with mild to moderate exacerbations (pooled odds ratio 1.09, 95% CI 0.75–1.59, I2 = 18%. Inpatients with severe exacerbations had a substantial benefit on treatment failure rates (pooled odds ratio of 0.25, 95% CI 0.16–0.39, I2 = 0%; number-needed to treat of 4, 95% CI 3–5 and on mortality (pooled odds ratio of 0.20, 95% CI 0.06–0.62, I2 = 0%; number-needed to treat of 14, 95% CI 12–30. Conclusion Antibiotics effectively reduce treatment failure and mortality rates in COPD patients with severe exacerbations. For patients with mild to moderate exacerbations, antibiotics may not be generally indicated and further research is needed to guide antibiotic prescription in these patients.

    Antibiotics as emerging contaminants are of global concern due to the development of antibiotic resistant genes potentially causing superbugs. Current wastewater treatment technology cannot sufficiently remove antibiotics from sewage, hence new and low-cost technology is needed. Adsorptive materials have been extensively used for the conditioning, remediation and removal of inorganic and organic hazardous materials, although their application for removing antibiotics has been reported for ~30 out of 250 antibiotics so far. The literature on the adsorptive removal of antibiotics using different adsorptive materials is summarized and critically reviewed, by comparing different adsorbents with varying physicochemical characteristics. The efficiency for removing antibiotics from water and wastewater by different adsorbents has been evaluated by examining their adsorption coefficient (Kd) values. For sulfamethoxazole the different adsorbents followed the trend: biochar (BC)> multi-walled carbon nanotubes (MWCNTs)>graphite = clay minerals, and for tetracycline the adsorptive materials followed the trend: SWCNT > graphite > MWCNT = activated carbon (AC) > bentonite = humic substance = clay minerals. The underlying controlling parameters for the adsorption technology have been examined. In addition, the cost of preparing adsorbents has been estimated, which followed the order of BCs < ACs < ion exchange resins < MWCNTs < SWCNTs. The future research challenges on process integration, production and modification of low-cost adsorbents are elaborated. PMID:26057999

    In order to exploit the potential benefits of antimicrobial combination therapy, we need a better understanding of the circumstances under which pharmacodynamic interactions expected. In this study, Pharmacodynamic interactions between silver nanoparticle (SNP) and topical antibiotics such as Cefazolin (CEF), Mupirocin (MUP), Gentamycin (GEN), Neomycin (NEO), Tetracycline (TET), Vancomycin (VAN) were investigated using the MIC test, Combination assay followed by Fractional Inhibitory concentration Index and Agar well diffusion method. SNP + MUP, SNP + NEO, SNP + VAN combinations showed Synergism (SN) and SNP + CEF, SNP + GEN, SNP + TET showed Partial synergism (PS) against Staphylococcus aureus. Four combinations (SNP + CEF, SNP + MUP, SNP + GEN, SNP + VAN) showed SN, SNP + TET showed PS and Indifferent effect (ID) were observed for SNP + NEO against Pseudomonas aeruginosa. SN was observed for SNP + CEF, SNP + GEN, SNP + NEO, SNP + TET and SNP + MUP showed ID, SNP + VAN showed PS against Escherichia coli. In addition, we elucidated the possible mechanism involved in the pharmacodynamic interaction between SNP-topical antibiotics by increased ROS level, membrane damage following protein release, K+ leakage and biofilm inhibition. Thus, our findings support that conjugation of the SNP with topical antibiotics have great potential in the topical formulation when treating complex resistant bacterial infections and where there is a need of more concentration to kill pathogenic bacteria.

    Oral and topical antibiotics are commonly prescribed in dermatologie practice, often for noninfectious disorders, such as acne vulgaris and rosacea. Concerns related to antibiotic exposure from both medical and nonmedical sources require that clinicians consider in each case why and how antibiotics are being used and to make appropriate adjustments to limit antibiotic exposure whenever possible. This first article of a three-part series discusses prescribing patterns in dermatology, provides an overview of sources of antibiotic exposure, reviews the relative correlations between the magnitude of antibiotic consumption and emergence of antibiotic resistance patterns, evaluates the impact of alterations in antibiotic prescribing, and discusses the potential relevance and clinical sequelae of antibiotic use, with emphasis on how antibiotics are used in dermatology.

  1. Topical and oral antibiotics for acne vulgaris.

    Del Rosso, James Q

    2016-06-01

    Antibiotics, both oral and topical, have been an integral component of the management of acne vulgaris (AV) for approximately 6 decades. Originally thought to be effective for AV due to their ability to inhibit proliferation of Propionibacterium acnes, it is now believed that at least some antibiotics also exert anti-inflammatory effects that provide additional therapeutic benefit. To add, an increase in strains of P acnes and other exposed bacteria that are less sensitive to antibiotics used to treat AV have emerged, with resistance directly correlated geographically with the magnitude of antibiotic use. Although antibiotics still remain part of the therapeutic armamentarium for AV treatment, current recommendations support the following when used to treat AV: 1) monotherapy use should be avoided; 2) use benzoyl peroxide concomitantly to reduce emergence of resistant P acnes strains; 3) oral antibiotics should be used in combination with a topical regimen for moderate-to-severe inflammatory AV; and 4) use oral antibiotics over a limited duration to achieve control of inflammatory AV with an exit plan in place to discontinue their use as soon as possible. When selecting an oral antibiotic to treat AV, potential adverse effects are important to consider. PMID:27416309

    2010-01-01

    In antibiotic therapy it is necessary to use drugs active against the pathogen in its association with the host normal microflora. The aim of the study was to investigate modification of antibiotic resistance under conditions of the pathogen association with the representatives of the host normal microflora and to develop the microbiological criteria for determining effectiveness of antibacterials. Modification of microbial antibiotic resistance was investigated in 408 associations. Various changes in the antibiotic resistance of the strains were revealed: synergism, antagonism and indifference. On the basis of the results it was concluded that in the choice of the antibiotic active against Staphylococcus aureus and Streptococcus pyogenes the preference should be given to oxacillin, gentamicin and levomycetin, since the resistance of the pathogens to these antibiotics under the association conditions did not increase, which could contribute to their destruction, whereas the resistance of the normoflora increased or did not change, which was important for its retention in the biocenosis. The data on changeability of the antibiotic resistance of the microbial strains under the association conditions made it possible to develop microbiological criteria for determining effectiveness of antibiotics in the treatment of inflammatory diseases of microbial etiology (RF Patent No. 2231554).

    Infection control is very important in burn care units, because burn wound infection is one of the main causes of morbidity and mortality among burn patients. Thus, the appropriate prescription of antibiotics can be helpful, but unreasonable prescription can have detrimental consequences, including greater expenses to patients and community alike. The aim of this study was to determine the effect of antibiotic therapy on the emergence of antibiotic-resistant bacteria. 525 strains of Pseudomonas aeruginosa, Acinetobacter baumannii and Staphylococcus aureus were isolated from 335 hospitalized burn patients. Antibiotic susceptibility tests were performed after identification the strains. The records of patients were audited to find the antibiotic used. The results indicated that P. aeruginosa is the most prevalent Gram-negative bacteria. Further, it showed a relation between abuse of antibiotics and emergence of antibiotic resistance. Control of resistance to antibiotics by appropriate prescription practices not only facilitates prevention of infection caused by multi-drug resistant (MDR) microorganisms, but it can also decrease the cost of treatment.

    International Nuclear Information System (INIS)

    To find out the incidence of surgical site infection in clean general surgery cases operated without prophylactic antibiotics. One hundred and twenty-four clean surgical cases operated without antibiotic prophylaxis between July 2003 and December 2004, were studied and these were compared with similar number of cases who received antibiotics. The data was collected and analyzed using software SPSS (version 10.0). Chi-square and student-t test were used to analyze the association between antibiotics and wound infection. The most frequent operation was repair of various hernias, 69.3% in group A and 75% in group B. More operations were carried out between 21-30 years, 38.7% in group A and 41.9% in group B. Surgical site infection occurred in one patient (0.8%) in each group. Chi-square test (0.636) applied to group A and B showed no association of infection and administration/ no administration of antibiotics (p > 0.25). The t-test applied on group A and B (t=0) also showed no significant difference between administration of antibiotics/ no-antibiotics and infection (p > 0.25). The use of prophylactic antibiotic in clean, non implant and elective cases is unnecessary. (author)

    2016-05-01

    Despite all the major breakthroughs in antibiotic development and treatment procedures, there is still no long-term solution to the bacterial antibiotic resistance problem. Among all the known types of resistance, adaptive resistance (AdR) is particularly inconvenient. This phenotype is known to emerge as a consequence of concentration gradients, as well as contact with subinhibitory concentrations of antibiotics, both known to occur in human patients and livestock. Moreover, AdR has been repeatedly correlated with the appearance of multidrug resistance, although the biological processes behind its emergence and evolution are not well understood. Epigenetic inheritance, population structure and heterogeneity, high mutation rates, gene amplification, efflux pumps, and biofilm formation have all been reported as possible explanations for its development. Nonetheless, these concepts taken independently have not been sufficient to prevent AdR's fast emergence or to predict its low stability. New strains of resistant pathogens continue to appear, and none of the new approaches used to kill them (mixed antibiotics, sequential treatments, and efflux inhibitors) are completely efficient. With the advent of systems biology and its toolsets, integrative models that combine experimentally known features with computational simulations have significantly improved our understanding of the emergence and evolution of the adaptive-resistant phenotype. Apart from outlining these findings, we propose that one of the main cornerstones of AdR in bacteria, is the conjunction of two types of mechanisms: one rapidly responding to transient environmental challenges but not very efficient, and another much more effective and specific, but developing on longer time scales.

    The decline in the rate of new antibiotic discovery is of growing concern, and new antibacterial strategies must now be explored. This review brings together research in two fields (metals in biology and antibiotics) in the hope that collaboration between scientists working in these two areas will lead to major advances in understanding and the development of new approaches to tackling microbial pathogens. Metals have been used as antiseptics for centuries. In this review, we focus on iron, an essential trace element that can nevertheless be toxic to bacteria. We review the many situations in which iron and antibiotics have combinatorial effects when used together. Understanding the molecular relationships between iron and antibiotics, from pure chemistry to gene reprogramming via biochemical competition, is important not only to increase basic knowledge, but also for the development of treatments against pathogens, with a view to optimizing antibiotic efficacy.

    The enediyne polyketides are secondary metabolites isolated from a variety of Actinomycetes. All members share very potent anticancer and antibiotic activity, and prospects for the clinical application of the enediynes has been validated with the recent marketing of two enediyne derivatives as anticancer agents. The biosynthesis of these compounds is of interest because of the numerous structural features that are unique to the enediyne family. The gene cluster for five enediynes has now been cloned and sequenced, providing the foundation to understand natures' means to biosynthesize such complex, exotic molecules. Presented here is a review of the current progress in delineating the biosynthesis of the enediynes with an emphasis on the model enediyne, C-1027. PMID:18397168

Data of antibiotic consumption were obtained from hospital pharmacy department on February–September 2011. Data were processed using the ATC/DDD and DU90% method. There were 390,98 DDD/100 bed days and 381,34 DDD/100 bed days total of an-tbiotic use in 2009 and 2010. Thirty nine antibiotic were consumed in 2009 within 11 kind of antibiotics in DU90% segment (ceftriaxone, amoxicillin, cefotaxime, ciprofloxacin, levofloxacin, metronidazole, cefixime, doxycycline, thiamphenicol, cefodoxime, cefalexin and 44 antibiotic were consumed in 2010 within 18 kind of antibiotics in DU90% segment (ceftriaxone, ciprofloxacin, amoxicillin, cefixime, levofloxacin, cefadroxil, cefotaxime, metronidazole, thiamphenicol, doxycycline, clindamycin, chloramphenicol, amikacin, sulbactam, gentamycin, streptomycin, cefoperazone, canamycin. There were decline of antibiotic use that followed decline number of bed days/year in 2009–2010, but in both antibiotic kind and quantity of DU90% antibiotic group were increased.

  19. Abiotic degradation of antibiotic ionophores

    International Nuclear Information System (INIS)

    Hydrolytic and photolytic degradation were investigated for the ionophore antibiotics lasalocid, monensin, salinomycin, and narasin. The hydrolysis study was carried out by dissolving the ionophores in solutions of pH 4, 7, and 9, followed by incubation at three temperatures of 6, 22, and 28 °C for maximum 34 days. Using LC–MS/MS for chemical analysis, lasalocid was not found to hydrolyse in any of the tested environments. Monensin, salinomycin, and narasin were all stable in neutral or alkaline solution but hydrolysed in the solution with a pH of 4. Half-lives at 25 °C were calculated to be 13, 0.6, and 0.7 days for monensin, salinomycin, and narasin, respectively. Absorbance spectra from each compound indicated that only lasalocid is degraded by photolysis (half-life below 1 h) due to an absorbance maximum around 303 nm, and monensin, salinomycin, and narasin are resistant to direct photolysis because they absorb light of environmentally irrelevant wavelengths. -- Highlights: •Constants for calculation of hydrolysis rates are estimated. •At 25 °C and a pH of 4, monensin hydrolyses with a half-life (t1/2) of 13 days. •Salinomycin and narasin hydrolyse with t1/2 of half a day at 25 °C and a pH of 4. •Lasalocid does not hydrolyse, but is likely to be susceptible to direct photolysis. •Monensin, salinomycin and narasin are not susceptible to direct photolysis. -- Antibiotic ionophores were found to undergo either hydrolysis in acidic environments (monensin, salinomycin, and narasin) or photolysis (lasalocid)

    Over the past decade, there has been a growing recognition of the increasing growth of antibiotic resistant bacteria and a relative decline in the production of novel antibacterial therapies. The combination of these two forces poses a potentially grave threat to global health, in both developed and developing countries. Current market forces do not provide appropriate incentives to stimulate new antibiotic development, thus we propose a new incentive mechanism: the Options Market for Antibiotics. This mechanism, modelled on the principle of financial call options, allows payers to buy the right, in early stages of development, to purchase antibiotics at a discounted price if and when they ever make it to market approval. This paper demonstrates the effect of such a model on the expected Net Present Value of a typical antibacterial project. As part of an integrated strategy to confront the impending antibiotic crisis, the Options Market for Antibiotics may effectively stimulate corporate and public investment into antibiotic research and development.

    Full Text Available Bacterial infections are raising serious concern across the globe. The effectiveness of conventional antibiotics is decreasing due to global emergence of multi-drug-resistant (MDR bacterial pathogens. This process seems to be primarily caused by an indiscriminate and inappropriate use of antibiotics in non-infected patients and in the food industry. New classes of antibiotics with different actions against MDR pathogens need to be developed urgently. In this context, this review focuses on several ways and future directions to search for the next generation of safe and effective antibiotics compounds including antimicrobial peptides, phage therapy, phytochemicals, metalloantibiotics, LPS and efflux pump inhibitors to control the infections caused by MDR pathogens.

    Before the development of the first antimicrobial agents, bacteria already had demonstrated an ability to adapt to stress in the environment, resulting in the development of resistance that often makes the prevailing antibiotic treatment ineffective. The response to antimicrobial resistance in the medical community has been to use new or alternative antibiotics not previously used against the resistant bacteria. The pharmaceutical industry has responded to the resistance problem by producing newer antibiotics, either as modifications of currently existing compounds or as combinations of compounds that may inhibit or bypass the bacterial resistance mechanisms. The development of new antibiotics is a lengthy and costly process. To be successful, the pharmaceutical industry must anticipate the changing needs of the medical community, as well as the dynamic process of antimicrobial resistance. The marketing of new antimicrobial agents must be adaptable to the potential environmental pressures that induce bacterial resistance in order to ensure the longevity of the agents. PMID:10654633

    effective by 90.62%. The top three complaints of patients prescribed antibiotic were fever (83.64%, urinary tract complaints (73.58%, and sore throat (47.79%. Clinicians declared that they had received drug/antibiotic usage training during undergraduation by 52.5%; postgraduation by 67.9%; they received training from a university by 63.1%; and 60.0% of them said they want to receive training. The ones who want to receive training wanted to receive it from infectious disease specialist by 36.4%; from a university by 30.9%; from Ministry of Health by 22.3%. The frequency of antibiotic prescription is declared to be low by the clinicians. On the other hand, ratio of usage of guidelines is low and there is need to take measures and planning of training to increase it. Clinicians declare that they request laboratory tests, but the laboratory results doesn't influence their antibiotic drug selection.[¤]CONCLUSION[|]The choice of the antibiotic is a major concern for the struggle of resistance development. For empirical treatment resistance rates in that region should be kept in mind and priority should be given to the first choice drugs, and the treatment should be revised according to the result of patient-specific antibiotic susceptibility testing. For the detection of region-specific resistance rates in our country, the data of the National Antibiotic Resistance Surveillance System that has been established can be used. In order to explain the situation to medical doctors, guidelines and activities such as the European Antibiotic Awareness Day campaigns should be utilized. Undergraduate and postgraduate rational drug/antibiotic usage trainings and evidencebased medical practices of physicians should be increased.[¤

    Full Text Available To evaluate antibiotic consumption in the pediatric wards of Emilia-Romagna Region, from 2004 to 2011, with a focus on the antibiotics reserved to the most serious infections, and to analyse the ADRs reported for antibiotics by the pediatric wards of Emilia-Romagna hospitals.Reference population was represented by all the patients (0-14 years old admitted to the pediatric wards of all the hospitals of Emilia-Romagna Region. Drug consumption was expressed as number of DDDs per 100 Bed-Days (BD and data were analysed by active substance, by therapeutic subgroups or by ward type. The time trends of antibiotic consumption were statistically analysed by linear regression. All the suspected ADR reports associated with antibiotics, reported between January 2004 and December 2011 were drawn by the Italian Spontaneous Reporting Database.Overall antibiotic consumption showed only a slight increase (p = 0.224. Among the pediatric wards, pediatric surgery showed the highest increase from 2004 to 2011 (p = 0.011. Penicillins and β-lactamase inhibitors was the first therapeutic group with a statistically significant increase over years (p = 0.038, whereas penicillins with extended spectrum presented a statistically significant reduction (p = 0.008. Moreover, only 5 drugs out of the 8 antibiotics reserved to the most serious infections were used. Pharmacovigilance data showed 27 spontaneous ADR reports associated to ATC J01 drugs. Amoxicillin/clavulanic acid had the highest number of ADR reports (n = 7.The steadily increasing consumption in penicillins and β-lactamase inhibitors, in association with a considerable decrease of plain penicillins, raises a serious concern. Pharmacovigilance reports seem to suggest a safe use of antibiotics in the hospital setting of Emilia-Romagna. Further studies to investigate the reason for prescribing antibiotics in children inpatients are needed.

  5. Antibiotic-Resistant Neisseria gonorrhoeae Spread Faster with More Treatment, Not More Sexual Partners.

    The sexually transmitted bacterium Neisseria gonorrhoeae has developed resistance to all antibiotic classes that have been used for treatment and strains resistant to multiple antibiotic classes have evolved. In many countries, there is only one antibiotic remaining for empirical N. gonorrhoeae treatment, and antibiotic management to counteract resistance spread is urgently needed. Understanding dynamics and drivers of resistance spread can provide an improved rationale for antibiotic management. In our study, we first used antibiotic resistance surveillance data to estimate the rates at which antibiotic-resistant N. gonorrhoeae spread in two host populations, heterosexual men (HetM) and men who have sex with men (MSM). We found higher rates of spread for MSM (0.86 to 2.38 y-1, mean doubling time: 6 months) compared to HetM (0.24 to 0.86 y-1, mean doubling time: 16 months). We then developed a dynamic transmission model to reproduce the observed dynamics of N. gonorrhoeae transmission in populations of heterosexual men and women (HMW) and MSM. We parameterized the model using sexual behavior data and calibrated it to N. gonorrhoeae prevalence and incidence data. In the model, antibiotic-resistant N. gonorrhoeae spread with a median rate of 0.88 y-1 in HMW and 3.12 y-1 in MSM. These rates correspond to median doubling times of 9 (HMW) and 3 (MSM) months. Assuming no fitness costs, the model shows the difference in the host population's treatment rate rather than the difference in the number of sexual partners explains the differential spread of resistance. As higher treatment rates result in faster spread of antibiotic resistance, treatment recommendations for N. gonorrhoeae should carefully balance prevention of infection and avoidance of resistance spread.

    Full Text Available The interest in measuring the health of populations, through measuring the demand and offers of health care, is deeply rooted in history. Population health indicators in use today are built upon from mortality measures from the 1500s; regular census information starting from the 1800s; civil registration records of vital statistics commencing in the 1850s; regular national surveys, which were first initiated in the 1950s; and health system and other administrative databases used widely since the 1960s. The ancient Greeks believed that the God of medicine had two daughters: Hygeia and Panacea, the first was the goddess of prevention and wellness, while the second was the goddess of treatment. Thus suggesting that people have long believed that there is more to health than health care. Today the actual concept of population health recognizes many interconnected aspects of society, the environment, and individuals all contributing to health. To increase opportunities for comparability, more valid, comprehensive and standardized ways of measuring and reporting on population health indicators are needed. The use of health indicators contributes to overall population health goals, namely improving the health populations, reducing health inequalities and measuring the performance of health care system. The objective of performance assessment is to provide governments and populations with information about the state of their health care system.

  8. Processing Needs

    International Nuclear Information System (INIS)

    Concerning processing needs the following recommendations can be made: Encourage and support spectrum-averaged cross section measurements for data validation. For example, measurements of constants for neutron activation analysis (thermal capture and resonance integrals), astrophysics cross sections (MACS, e.g. corresponding to a 30 keV Maxwellian spectrum), 252Cf spontaneous fission spectrum averaged cross sections, etc. The latter could help to resolve many issues related to uncertainties in the capture cross section in the energy region between 100 keV and a few MeV; Continue to develop and improve web based and off-line data visualisation tools, striving for generality as well as user-friendliness; Continue to support developments for the generation of covariance data of experimental measurements as well as evaluated nuclear data; Regarding the issue of independent processing codes, the generally available PREPRO series is highly esteemed and truly valuable, but it lacks, by design the following: a module to generate scattering matrices; a module to generate temperature dependent self-shielded cross sections in the unresolved resonance region; processing of fission neutron multiplicity; treatment of covariances; Perhaps Red Cullen might be willing to undertake this work. The details of additional modules to be developed include also treatment of covariances. All these modules should be clearly identified. Enhancement of the processing of covariance matrices could be sought by acquiring and making generally available a code that is already developed (e.g. drawing from the experience in Japan)

    Exploration and extraction activities related to energy and mineral resources in the Borderlands—such as coal-fired power plants, offshore drilling, and mining—can create issues that have potentially major economic and environmental implications. Resource assessments and development projects, environmental studies, and other related evaluations help to understand some of these issues, such as power plant emissions and the erosion/denudation of abandoned mine lands. Information from predictive modeling, monitoring, and environmental assessments are necessary to understand the full effects of energy and mineral exploration, development, and utilization. The exploitation of these resources can negatively affect human health and the environment, its natural resources, and its ecological services (air, water, soil, recreation, wildlife, etc.). This chapter describes the major energy and mineral issues of the Borderlands and how geologic frameworks, integrated interdisciplinary (geobiologic) investigations, and other related studies can address the anticipated increases in demands on natural resources in the region.

    Full Text Available Upper respiratory tract infections (URTIs are common in children and represent a significant cause of antibiotic abuse which contributes to the development of antibiotic resistance. A survey was conducted in Cyprus in 2006 to assess parents’ and pediatricians’ Knowledge, Attitude and Practices (KAP concerning the role of antibiotics in children with URTIs. A school-based stratified geographic clustering sampling was used and a pre-tested KAP questionnaire was distributed. A different questionnaire was distributed to paediatricians. Demographic factors associated with antibiotic misuse were identified by backward logistic regression analysis. The parental overall response rate was 69.3%. Parents (N = 1,462 follow pediatricians advice and rarely administer antibiotics acquired over the counter. Although a third expects an antibiotic prescription for URTI symptoms, most deny pressuring their doctors. Low parental education was the most important independent risk factor positively related to antibiotic misuse (OR = 2.88, 95%CI 2.02 to 4.12, p < 0.001. Pediatricians (N = 33 denied prescribing antibiotics after parental pressure but admit that parents ask for antibiotics and believe they expect antibiotic prescriptions even when not needed. In conclusion, Cypriotic parents trust their primary care providers. Although it appears that antibiotic misuse is not driven by parental pressure, the pediatricians’ view differs.

    Prevalence of antibiotic-resistant bacteria in wastewater effluents is concerned as an emerging contaminant. To estimate antibiotic resistance in secondary effluents of municipal wastewater treatment plants, antibiotic tolerance of heterotrophic bacteria, proportion of antibiotic-resistant bacteria and hemi-inhibitory concentrations of six antibiotics (penicillin, ampicillin, cefalexin, chloramphenicol, tetracycline and rifampicin) were determined at two wastewater treatment plants (WWTPs) in Beijing. The results showed that proportions of ampicillin-resistant bacteria in WWTP-G and chloramphenicol-resistant bacteria in WWTP-Q were highest to 59% and 44%, respectively. The concentrations of ampicillin-resistant bacteria in the effluents of WWTP-G and WWTP-Q were as high as 4.0 x 10(3) CFU x mL(-1) and 3.5 x 10(4) CFU x mL(-1), respectively; the concentrations of chloramphenicol-resistant bacteria were 4.9 x 10(2) CFU x mL(-1) and 4.6 x 10(4) CFU x mL(-1), respectively. The data also indicated that the hemi-inhibitory concentrations of heterotrophic bacteria to 6 antibiotics were much higher than common concentrations of antibiotics in sewages, which suggested that antibiotic-resistant bacteria could exist over a long period in the effluents with low concentrations of antibiotics. Antibiotic-resistant bacteria could be a potential microbial risk during sewage effluent reuse or emission into environmental waters. PMID:22295644

    The emergence and spread of antibiotic resistance represents one of the most important public health concerns and has been linked to the widespread use of antibiotics in veterinary and human medicine. The overall elimination of antibiotics in conventional wastewater treatment plants is quite low; therefore, residual amounts of these compounds are continuously discharged to receiving surface waters, which may promote the emergence of antibiotic resistance. In this study, the ability of a fungal treatment as an alternative wastewater treatment for the elimination of forty-seven antibiotics belonging to seven different groups (β-lactams, fluoroquinolones, macrolides, metronidazoles, sulfonamides, tetracyclines, and trimethoprim) was evaluated. 77% of antibiotics were removed after the fungal treatment, which is higher than removal obtained in conventional treatment plants. Moreover, the effect of fungal treatment on the removal of some antibiotic resistance genes (ARGs) was evaluated. The fungal treatment was also efficient in removing ARGs, such as ermB (resistance to macrolides), tetW (resistance to tetracyclines), blaTEM (resistance to β-lactams), sulI (resistance to sulfonamides) and qnrS (reduced susceptibility to fluoroquinolones). However, it was not possible to establish a clear link between concentrations of antibiotics and corresponding ARGs in wastewater, which leads to the conclusion that there are other factors that should be taken into consideration besides the antibiotic concentrations that reach aquatic ecosystems in order to explain the emergence and spread of antibiotic resistance.

    We have defined a sensitivity profile for 22 antibiotics by extending previous work testing the entire KEIO collection of close to 4,000 single-gene knockouts in Escherichia coli for increased susceptibility to 1 of 14 different antibiotics (ciprofloxacin, rifampin [rifampicin], vancomycin, ampicillin, sulfamethoxazole, gentamicin, metronidazole, streptomycin, fusidic acid, tetracycline, chloramphenicol, nitrofurantoin, erythromycin, and triclosan). We screened one or more subinhibitory concentrations of each antibiotic, generating more than 80,000 data points and allowing a reduction of the entire collection to a set of 283 strains that display significantly increased sensitivity to at least one of the antibiotics. We used this reduced set of strains to determine a profile for eight additional antibiotics (spectinomycin, cephradine, aztreonem, colistin, neomycin, enoxacin, tobramycin, and cefoxitin). The profiles for the 22 antibiotics represent a growing catalog of sensitivity fingerprints that can be separated into two components, multidrug-resistant mutants and those mutants that confer relatively specific sensitivity to the antibiotic or type of antibiotic tested. The latter group can be represented by a set of 20 to 60 strains that can be used for the rapid typing of antibiotics by generating a virtual bar code readout of the specific sensitivities. Taken together, these data reveal the complexity of intrinsic resistance and provide additional targets for the design of codrugs (or combinations of drugs) that potentiate existing antibiotics.

    Antibiotics may be thought of as a common pool resource that can be depleted over time; the economics of this problem are relatively well known. The importance of antibiotics to human health means that limiting access through privatization is undesirable. Therefore, other solutions to prevent overuse are essential - stewardship programs, and for non-human use, taxation, all within the context of an international agreement. To solve problems of access while offering adequate rewards for innovation, a key tool is delinking prices from payment to innovators. PMID:26243241

    Bordetella avium continues to be an economic issue in the turkey industry as the causative agent of bordetellosis, which often leads to serious secondary infections. This study presents a broad characterization of the antibiotic resistance patterns in this diverse collection of B. avium strains collected over the past thirty years. In addition, the plasmid basis for the antibiotic resistance was characterized. The antibiotic resistance pattern allowed the development of a novel enrichment culture method that was subsequently employed to gather new isolates from diseased turkeys and a healthy sawhet owl. While a healthy turkey flock was shown to seroconvert by four weeks-of-age, attempts to culture B. avium from healthy turkey poults were unsuccessful. Western blot of B. avium strains using pooled serum from diseased and healthy commercial turkey flocks revealed both antigenic similarities and differences between strains. In sum, the work documents the continued exposure of commercial turkey flocks to B. avium and the need for development of an effective, inexpensive vaccine to control spread of the disease.

    Full Text Available We do not need to rehearse the grim story of the global rise of antibiotic resistant microbes. But what if it were possible to control the rate with which antibiotic resistance evolves by de novo mutation? It seems that some bacteria may already do exactly that: they modify the rate at which they mutate to antibiotic resistance dependent on their biological environment. In our recent study [Krašovec, et al. Nat. Commun. (2014, 5, 3742] we find that this modification depends on the density of the bacterial population and cell-cell interactions (rather than, for instance, the level of stress. Specifically, the wild-type strains of Escherichia coli we used will, in minimal glucose media, modify their rate of mutation to rifampicin resistance according to the density of wild-type cells. Intriguingly, the higher the density, the lower the mutation rate (Figure 1. Why this novel density-dependent ‘mutation rate plasticity’ (DD-MRP occurs is a question at several levels.

    This report describes the synthesis and evaluation of glycosylated polyacrylate nanoparticles that have covalently-bound antibiotics within their framework. The requisite glycosylated drug monomers were prepared from one of three known antibiotics, an N-sec-butylthio beta-lactam, ciprofloxacin, and a penicillin, by acylation with 3-O-acryloyl-1,2-O-isopropylidene-5,6 bis((chlorosuccinyl)oxy)-d-glucofuranose (7) or 6-O-acetyl-3-O-acryloyl-1,2-O-isopropylidene-5-(chlorosuccinyl)oxy-alpha-d-glucofuranose (10). These acrylated monomers were subjected to emulsion polymerization in a 7:3 (w:w) mixture of butyl acrylate-styrene in the presence of sodium dodecyl sulfate as surfactant (3 weight %) and potassium persulfate as a radical initiator (1 weight %). The resulting nanoparticle emulsions were characterized by dynamic light scattering and found to have similar diameters ( approximately 40 nm) and size distributions to those of our previously studied systems. Microbiological testing showed that the N-sec-butylthio beta-lactam and ciprofloxacin nanoparticles both have powerful in vitro activities against methicillin-resistant Staphylococcus aureus and Bacillus anthracis, while the penicillin-bound nanoparticles have no antimicrobial activity. This indicates the need for matching a suitable antibiotic with the nanoparticle carrier. Overall, the study shows that even relatively large, polar acrylate monomers (MW>1000 amu) can be efficiently incorporated into the nanoparticle matrix by emulsion polymerization, providing opportunities for further advances in nanomedicine.

    Full Text Available Introduction & Objective: One of the mechanisms of antibiotic resistance in gram negative bac-teria, particularly Klebsiella pneumonia strains, is the production of Extended-Spectrum ? lactamase enzymes (ESBLs. Encoding genes of ESBLs are usually located on the plasmid and they are able to transfer to other gram-negative bacteria. Thus, due to the importance of resistance pattern recognition and its sensitivity to the ?- lactam antibiotics, the above men-tioned issue was examined in this study. Materials & Methods: In this study different clinical samples of Boroujerd and Hamadan Hos-pitals during 6 months were collected and identified by biochemical tests and Enterosystem kit. To confirm the strains, the Ure D gene was used as the internal gene of Klebsiella pneumoniae by PCR method. Antibiotic resistance by Disk diffusion method was performed. Phenotypic confirmatory test was used to determine the presence of ESBLs. MIC antibiotics of Ceftazidime and imipenem by E test method were determined. Results: The results showed that the highest rate of Klebsiella pneumoniae strains resistance was related to Cefexime antibiotics 46.7%, Ceftriaxone 43.3%, Azthrunam 43.3%, Cefo-taxime 41.7%, Cotrimaksazol 40.8% , Ceftazidim 36.7% and the least resistance was related to antibiotics Imipenem 0% Sprofluksasin 16.7%, Cefepime 25% and Gentamicin 26.7%. 56 strains( 46.7% were identified as ESBL –positive strains. Using E-test strip for Ceftazidim antibiotic, 66 strains were resistant , 10 strains intermediate ,and 44 strains were sensitive to Ceftazidim and by E test method for Imipenem antibiotic ,120 strains were sensitive. Conclusion: The high prevalence of antibiotic resistance and ESBLs production in the cities which were studied indicates the need for screening of ESBLs in clinical samples by labora-tory and prescribing appropriate antibiotics with ?-lactamase inhibitory power and antibiotics together with clavulanic by physicians.

  11. The need for energy

    International Nuclear Information System (INIS)

    The approach used by the nuclear energy industry regarding health and safety presents some difficulty to many people. Safety in an industry should be assessed only on a plant-by-plant basis. The labour movement feels there must be a balanced approach given to energy policy, with employment as a prime consideration. There must also be great emphasis on conservation, revewable resources and such matters as wind and solar energy. It is the position of the labour movement that Canada needs a national energy corporation. Higher prices for oil are not seen as being effective for stimulating either new production or conservation.

    Bacterial resistance to antibiotics is growing up day by day in both community and hospital setting, with a significant impact on the mortality and morbidity rates and the financial burden that is associated. In the last two decades multi drug resistant microorganisms (both hospital- and community-acquired) challenged the scientific groups into developing new antimicrobial compounds that can provide safety in use according to the new regulation, good efficacy patterns, and low resistance profile. In this review we made an evaluation of present data regarding the new classes and the new molecules from already existing classes of antibiotics and the ongoing trends in antimicrobial development. Infectious Diseases Society of America (IDSA) supported a proGram, called "the '10 × ´20' initiative", to develop ten new systemic antibacterial drugs within 2020. The microorganisms mainly involved in the resistance process, so called the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumanii, Pseudomonas aeruginosa, and enterobacteriaceae) were the main targets. In the era of antimicrobial resistance the new antimicrobial agents like fifth generation cephalosporins, carbapenems, monobactams, β-lactamases inhibitors, aminoglycosides, quinolones, oxazolidones, glycopeptides, and tetracyclines active against Gram-positive pathogens, like vancomycin-resistant S. aureus (VRSA) and MRSA, penicillin-resistant streptococci, and vancomycin resistant Enterococcus (VRE) but also against highly resistant Gram-negative organisms are more than welcome. Of these compounds some are already approved by official agencies, some are still in study, but the need of new antibiotics still does not cover the increasing prevalence of antibiotic-resistant bacterial infections. Therefore the management of antimicrobial resistance should also include fostering coordinated actions by all stakeholders, creating policy guidance, support for

    Full Text Available Objective: This study sought to explore the knowledge and attitudes of parents on the use of antibiotics among children that could serve as baseline data and provide further insight in planning and developing strategies for local health education purposes. Methods: A cross-sectional survey involving 500 parents who attended community pharmacies in Tetovo, Republic of Macedonia, was conducted using a self-administered questionnaire from October 2013 to January 2014. The questionnaire included demographics, knowledge and attitude statements of parents towards antibiotics. The data collected were analyzed using SPSS program, version 19.0. Descriptive statistics was used to summarize the data. In all statistical analyses, a p-value of <0.05 was considered statistically significant. Results: Nearly 40% of the parents demonstrated a moderate level of knowledge. The highest correct response in the knowledge part was the awareness of parents in using antibiotics to treat a bacterial infection (61.2%. However, most of the parents did not know that antibiotics cannot cure viral infections (59.6%. About 48.2% of the parents were aware of the antibiotic resistance as s result of the overuse. Concerning attitudes, 60.8% reported keeping any leftover antibiotics, 77.0% agreed that taking antibiotics when having cold symptoms could help their children recover faster, while, 74.6% wrongly agreed with the statement of appropriate use of antibiotics for prophylaxis’ measure. Conclusions: This study has documented the main areas that merit attention when parental knowledge on antibiotic use for their children is the concern, reflecting in some inappropriate attitudes as well. The findings highlight the need to devise effective interventions to decrease misconceptions regarding antibiotic use and to increase parents’ awareness for the risks of inappropriate use of antibiotics in children specifically and in the community at large.

    Abstract The aim of this study was to explore the knowledge, attitudes, and practices of village doctors regarding the prescribing of antibiotics for children under 15 years with upper respiratory tract infections (URTIs) in rural China. Twelve focus group discussions (FGDs) were conducted in Xianning, a prefecture-level city in rural China, during December 2014. We conducted 6 FGDs with 35 village doctors, 3 with 13 primary caregivers (11 parents), and 3 with 17 directors of township hospitals, county-level health bureaus, county-level Centers for Disease Control and Prevention, or county-level Chinese Food and Drug Administration offices. Audio records of the interviews were transcribed verbatim and analyzed using the thematic analysis approach. Participants believed that unnecessary antibiotic prescribing for children under 15 years with The occurrence of URTIs was a problem in village clinics in rural China. The discussions revealed that most of the village doctors had inadequate knowledge and misconceptions about antibiotic use, which was an important factor in the unnecessary prescribing. Village doctors and directors reported that the doctors’ fear of complications, the primary caregivers’ pressure for antibiotic treatment, and the financial considerations of patient retention were the main factors influencing the decision to prescribe antibiotics. Most of the primary caregivers insisted on antibiotics, even when the village doctors were reluctant to prescribe them, and they preferred to go to see those village doctors who prescribed antibiotics. The interviewees also gave their opinions on what would be the most effective measures for optimizing antibiotic prescriptions; these included educational/training campaigns, strict regulations on antibiotic prescription, and improved supervision. Findings emphasized the need to improve the dissemination of information and training/education, and implement legislation on the rational use of antibiotics. And it

    This study evaluated the potential concentrations of four antibiotics: ciprofloxacin (CIP), sulfamethoxazole (SUF), trimethoprim (TRI) and erythromycin (ERY) throughout the rivers of Europe. This involved reviewing national consumption rates together with assessing excretion and sewage treatment removal rates. From this information, it was possible to construct best, expected and worst case scenarios for the discharge of these antibiotics into rivers. Consumption data showed surprising variations, up to 200-fold in the popularity of different antibiotics across different European nations. Using the water resources model GWAVA which has a spatial resolution of approximately 6 × 9 km, river water concentrations throughout Europe were predicted based on 31-year climate data. The modelled antibiotic concentrations were within the range of measurements reported previously in European effluents and rivers. With the expected scenario, the predicted annual-average antibiotic concentrations ranged between 0 and 10 ng/L for 90% by length of surface waters. In the worst case scenario concentrations could reach between 0.1 and 1 μg/L at the most exposed locations. As both predicted and observed sewage effluent concentrations were below reported effect levels for the most sensitive aquatic wildlife, no direct toxicity in rivers is expected. Predicted river concentrations for CIP and ERY were closest to effect levels in wildlife, followed by SUF which was 2–3 orders of magnitude lower. TRI appeared to be of the least concern with around 6 orders of magnitude difference between predicted and effect levels. However, mixture toxicity may elevate this risk and antibiotic levels of 0.1–1 μg/L in hotspots may contribute to local environmental antibiotic resistance in microorganisms. - Highlights: • Antibiotic consumption varied up to 200-fold between European nations. • Antibiotic concentrations predicted to be 10 ng/L or less for most European rivers. • These antibiotic

    The ongoing development of metagenomic approaches is providing the means to explore antibiotic resistance in nature and address questions that could not be answered previously with conventional culture-based strategies. The number of available environmental metagenomic sequence datasets is rapidly expanding and henceforth offer the ability to gain a more comprehensive understanding of antibiotic resistance at the global scale. Although there is now evidence that the environment constitutes a vast reservoir of antibiotic resistance gene determinants (ARGDs) and that the majority of ARGDs acquired by human pathogens may have an environmental origin, a better understanding of their diversity, prevalence and ecological significance may help predict the emergence and spreading of newly acquired resistances. Recent applications of metagenomic approaches to the study of ARGDs in natural environments such as soil should help overcome challenges concerning expanding antibiotic resistances. PMID:21601510

  3. Do antibiotics decrease effectiveness of oral contraceptives?

    Science.gov (United States)

    Cottet, C

    1996-09-01

    The number of accidental pregnancies occurring in oral contraceptive (OC) users who are concurrently taking certain antibiotics and antifungal agents exceeds the 1% failure rate associated with OCs, suggesting some form of drug interaction. Two mechanisms of action have been proposed to explain this phenomenon. First, drugs such as rifampin and griseofulvin induce liver enzymes that break down the estrogen and progestin contained in OCs, reducing plasma hormone levels. Second, changes in the intestinal bacterial flora induced by penicillin and tetracycline may reduce the gut's absorption of hormones, also compromising efficacy. Since rifampin and griseofulvin are the medications most frequently implicated in accidental pregnancies in OC users, the induction of liver enzymes is the more probable, potent cause of failure. Although the risk of pregnancy due to OC-antibiotic interactions is extremely small, OC users prescribed antibiotics should be warned to use condoms or spermicides until the antibiotics are discontinued.

    ABSTRACT We recently investigated the applicability of antibiotic-treated recipient mice for transfer of different gut microbiota profiles. With this addendum we elaborate on perspectives and limitations of using antibiotics as an alternative to germ-free (GF) technology in microbial transplantation studies, and we speculate on the housing effect. It is possible to transfer host phenotypes via fecal transplantation to antibiotic-treated animals, but problems with reproducibility, baseline values, and antibiotic resistance genes should be considered. GF animals maintained in isolators still seem to be the best controlled models for long-term microbial transplantation, but antibiotic-treated recipients are also commonly utilized. We identify a need for systematic experiments investigating the stability of microbial transplantations by addressing 1) the recipient status as either GF, antibiotic-treated or specific pathogen free and 2) different levels of protected housing systems. In addition, the developmental effect of microbes on host physiological functions should be evaluated in the different scenarios. PMID:26744774

    Anahit Penesyan

    2015-03-01

    Full Text Available Bacterial resistance is a rapidly escalating threat to public health as our arsenal of effective antibiotics dwindles. Therefore, there is an urgent need for new antibiotics. Drug discovery has historically focused on bacteria growing in planktonic cultures. Many antibiotics were originally developed to target individual bacterial cells, being assessed in vitro against microorganisms in a planktonic mode of life. However, towards the end of the 20th century it became clear that many bacteria live as complex communities called biofilms in their natural habitat, and this includes habitats within a human host. The biofilm mode of life provides advantages to microorganisms, such as enhanced resistance towards environmental stresses, including antibiotic challenge. The community level resistance provided by biofilms is distinct from resistance mechanisms that operate at a cellular level, and cannot be overlooked in the development of novel strategies to combat infectious diseases. The review compares mechanisms of antibiotic resistance at cellular and community levels in the light of past and present antibiotic discovery efforts. Future perspectives on novel strategies for treatment of biofilm-related infectious diseases are explored.

  12. Intravenous to oral antibiotic switch therapy.

    Cunha, Burke A.

    2001-05-01

    I.v.-to-p.o. switch therapy has become the mainstay of antibiotic therapy for the majority of patients. I.v.-to-p.o. switch therapy is inappropriate for critically ill patients who require i.v. antibiotic therapy and should not be considered in patients who have the inability to absorb drugs. These exceptions constitute a very small percentage of hospitalized patients for which i.v.-to-p.o. switch therapy is ideal. I.v.-to-p.o. switch therapy is best achieved with antibiotics that have high bioavailability that result in the same blood and tissue concentrations of antibiotic as their intravenous counterpart and have few gastrointestinal side effects. Antibiotics ideal for i.v.-to-p.o. switch programs include chloramphenicol, clindamycin, metronidazole, TMP-SMX, fluconazole, itraconazole, voriconazole, doxycycline, minocycline, levofloxacin, gatifloxacin, moxifloxacin and linezolid. Antibiotics that may be used in i.v.-to-p.o. switch programs that have lower bioavailability but are effective include beta-lactams and macrolides. For antibiotics with no oral formulation, e.g., carbapenems, equivalent coverage must be provided with an oral antibiotic from an unrelated class. Excluding gastrointestinal malabsorptive disorders, disease state is not a determinant of suitability for i.v.-to-p.o. switch programs. I.v.-to-p.o. switch programs should be used in patients with any infectious disease disorder for which there is effective oral therapy and is not limited to certain infectious diseases. Oral absorption of antibiotics is near normal in all but the most critically ill patients. Therefore, even in sick, hospitalized individuals, p.o. therapy is appropriate. I.v-to-p.o. switch therapy has several important advantages including decreasing drug cost (i.v. vs. p.o.), decreasing length of stay permitting earlier discharge and optimal reimbursement and decreasing or eliminating i.v. line phlebitis and sepsis with its cost implications. Clinicians should consider all

    Full Text Available Aim. To determine the antibiotic prescribing habits for pulpal and periapical pathology among dentists in Hyderabad city, India. Methodology. A total of 246 questionnaires were distributed to all the dentists registered with the local dental branch. Demographic details and questions regarding type and dosage of antibiotics prescribed for allergic and nonallergic patients were recorded. Inferential statistics were performed, and P<0.05 was considered statistically significant. Results. The response rate for the study was 87.8%. Around 148 (68.5% of respondents regularly prescribed antibiotics for endodontic management. The first antibiotic of choice for patients with no history of medical allergies was a combination of amoxicillin and metronidazole, followed by amoxicillin alone (29.1%. The first antibiotic of choice in case of allergy to penicillin was erythromycin. Necrotic pulp with acute apical periodontitis with swelling and moderate/severe preoperative symptom was the condition most commonly identified for antibiotic therapy (92.1%. Conclusion. The present study reveals that the overall antibiotic prescribing practices among this group of dentists were quite high, and there is a need for more educational initiatives to rationalize the use of antibiotics in dentistry.

    Full Text Available Open fractures are at risk of serious infection and, if infected, require several surgical interventions and courses of systemic antibiotics. We investigated a new injectable formulation that simultaneously hardens in vivo to form a porous scaffold for bone repair and delivers antibiotics at high concentrations to the local site of infection. Duration of antimicrobial activity against Staphylococcus aureus was determined using the serial plate transfer test. Ultimate compressive strength and porosity of the material was measured with and without antibiotics. The material was evaluated in vivo in an ovine medial femoral condyle defect model contaminated with S. aureus. Sheep were sacrificed at either 2 or 13 weeks and the defect and surrounding bone assessed using micro-computed tomography and histology. Antimicrobial activity in vitro persisted for 19-21 days. Sheep with antibiotic-free material and bacteria became infected, while those with antibiotic-containing material and bacteria did not. Similarly, new bone growth was seen in uninoculated animals with plain polymer, and in those with antibiotic polymer with bacteria, but not in sheep with plain polymer and bacteria. The antibiotic-impregnated scaffolds were effective in preventing S. aureus infections whilst supporting bone growth and repair. If translated into clinical practice, this approach might reduce the need for systemic antibiotics.

Duration of antimicrobial activity against Staphylococcus aureus was determined using the serial plate transfer test. Ultimate compressive strength and porosity of the material was measured with and without antibiotics. The material was evaluated in vivo in an ovine medial femoral condyle defect model contaminated with S. aureus. Sheep were sacrificed at either 2 or 13 weeks and the defect and surrounding bone assessed using micro-computed tomography and histology. Antimicrobial activity in vitro persisted for 19-21 days. Sheep with antibiotic-free material and bacteria became infected, while those with antibiotic-containing material and bacteria did not. Similarly, new bone growth was seen in uninoculated animals with plain polymer, and in those with antibiotic polymer with bacteria, but not in sheep with plain polymer and bacteria. The antibiotic-impregnated scaffolds were effective in preventing S. aureus infections whilst supporting bone growth and repair. If translated into clinical practice, this approach might reduce the need for systemic antibiotics. PMID:24908426

    Full Text Available Widespread emergence of multidrug resistant (MDR bacterial pathogens is a problem of global dimension. MDR infections are difficult to treat and frequently associated with high mortality. More than one antibiotic is commonly used to treat such infections, but scientific evidence does not favor use of combination therapy in most cases. However, there are certain subgroups where combination therapy may be beneficial, e.g. sepsis due to carbapenem-resistant Enterobacteriaceae (CRE, bacteremic pneumococcal pneumonia, and patients with multiple organ failure. Well-designed prospective studies are needed to clearly define the role of combination therapy in these subgroups.

    Respiratory anthrax, in the absence of early antibiotic treatment, is a fatal disease. This study aimed to test the efficiency of antibiotic therapy in curing infected animals and those sick with anthrax. Postexposure prophylaxis (24 h postinfection [p.i.]) of guinea pigs infected intranasally with Bacillus anthracis Vollum spores with doxycycline, ofloxacin, imipenem, and gentamicin conferred protection. However, upon termination of treatment, the animals died from respiratory anthrax. Combi...

    Aptamers are short, single stranded DNA or RNA oligonucleotides that are able to bind specifically and with high affinity to their non-nucleic acid target molecules. This binding reaction enables their application as biorecognition elements in biosensors and assays. As antibiotic residues pose a problem contributing to the emergence of antibiotic-resistant pathogens and thereby reducing the effectiveness of the drug to fight human infections, we selected aptamers targeted against the aminog...

    Burn wound infections is the leading cause of morbidity and mortality in burn trauma patients. Although burn wound is sterile at the beginning, because of risk factors such as prolonged hospital stay, immunesuppression and burn affecting large body surface area, colonisation firstly with Staphylococcus aureus and then Pseudomonas aeruginosa will occur later. Delay in wound closure and treatment with broad-spectrum antibiotic will result wound colonisation with antibiotic-resistant bacteria. T...

    Many pathogenic bacteria can enter phagocytic cells and replicate in them, and these intracellular bacteria are difficult to treat because the recommended antibiotics do not transport into the cells efficiently. Examples include food-borne bacteria such as Salmonella and Listeria as well as more toxic bacteria such as Brucella and the Mycobacteria that lead to tuberculosis. Current treatments utilize aminoglycoside antibiotics that are polar and positively charged and such drugs do not ente...
