Summary of your 'study carrel' ============================== This is a summary of your Distant Reader 'study carrel'. The Distant Reader harvested & cached your content into a collection/corpus. It then applied sets of natural language processing and text mining against the collection. The results of this process was reduced to a database file -- a 'study carrel'. The study carrel can then be queried, thus bringing light specific characteristics for your collection. These characteristics can help you summarize the collection as well as enumerate things you might want to investigate more closely. This report is a terse narrative report, and when processing is complete you will be linked to a more complete narrative report.

Health; United; animal; antibiotic summary = This chapter examines the evidence for antibiotic resistance in the United States and globally, the public health implications, and the impact of—and related industry and political responses to—antibiotic use in animal feed. The major stakeholders include pharmaceutical companies, production integrators, feed suppliers, farm groups, producers, restaurants, food retailers, the public, the medical community, the scientific community, government regulators and policy makers. In 1969, the United Kingdom''s (UK) Parliament received the Swann Report, which concluded that using antimicrobials at sub-therapeutic levels in food-producing animals created risks to human and animal health (Joint Committee on the use of Antibiotics in Animal Husbandry and Veterinary Medicine 1969). This scenario could be exacerbated to the extent FSIS approves additional international facilities, local regulations, and inspections as "equivalent to the United States." Future trade agreements will need to include provisions which address reduced use of medically important antibiotics in producing food animals. doi = 10.1007/978-3-319-92138-9_15 id = cord-281188-0cql96hu author = Baquero, Fernando title = Proximate and ultimate causes of the bactericidal action of antibiotics date = 2020-10-06 keywords = Escherichia; antibiotic; bacteria; cell; dna; kill summary = (1) only free drug is active against the target bacteria, and protein binding of the drug decreases the rate of killing 19 ; (2) there are structures (such as porins) and mechanisms facilitating drug uptake, but also barriers that prevent the drug from entering the cells 20 ; (3) the drug can be pumped out, so the concentration needed for killing takes longer to achieve 21, 22 ; (4) the antibiotics with weak target-binding affinity will take longer to achieve the doses necessary for killing than those with greater affinity 23 ; (5) the targeted function might increase in the presence of the drug, thereby compensating for the inhibition by the drug 24 ; (6) the target function corresponds to the build-up of a cellular structure with slow turnover, which increases the amount of time for the antibiotic to kill 25,26 ; (7) the cells repair the damage produced by the antibiotics at rates that differ between drugs 27 ; (8) the damaged bacteria have inducible antibiotic-deactivating mechanisms 28 ; (9) the bacteria use alternative metabolic pathways that, to some extent, bypass those inhibited by the antibiotic 29, 30 ; (10) antibiotics differ in the extent to which they induce reactive oxygen species (ROS; deleterious) or SOS (potentially protective) responses and thereby the rate at which they kill the exposed bacteria [31] [32] [33] [34] ; (11) members of the antibiotic-exposed populations are either www.nature.com/nrmicro not replicating or are replicating slowly, and as such are killed at lower rates than the more active members of the population or their death is delayed; (12) the antibiotics produce a kind of ''stationary phase'' by activating the general RpoS-mediated stringent response 35 . doi = 10.1038/s41579-020-00443-1 id = cord-351231-aoz5jbf1 author = Bartlett, John G. title = Why Infectious Diseases date = 2014-09-15 keywords = States; United; antibiotic; disease; infectious summary = The value of the infectious disease practitioner is now magnified by the crisis of antibiotic resistance, the expanding consequences of international travel, the introduction of completely new pathogen diagnostics, and healthcare reform with emphasis on infection prevention and cost in dollars and lives. The point is that epidemics are the domain of infectious diseases and public health, with the expectation for management or prevention of outbreaks with requirements for detection, reporting, isolation, and case management. This began with a patient transferred from a New York City hospital with a KPC infection and became the source of an institutional outbreak that required extraordinary efforts to control, including a wall constructed to isolate cases, removal of plumbing (as a possible source), use of matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) molecular diagnostics to detect cases and carriers, hydrogen peroxide room aerosols, and "whole house" surveillance cultures. The new healthcare system should value infectious disease expertise based on its important role in addressing resistance and costs associated with nosocomial infections. doi = 10.1093/cid/ciu441 id = cord-259945-nmjwzk4e author = Bent, Stephen title = Antibiotics in acute bronchitis: a meta-analysis date = 1999-07-07 keywords = acute; antibiotic summary = Only randomized trials that enrolled otherwise healthy patients with a diagnosis of acute bronchitis, used an antibiotic in the treatment group and a placebo in the control group, and provided sufficient data to calculate an effect size were included. Only randomized trials that enrolled otherwise healthy patients with a diagnosis of acute bronchitis, used an antibiotic in the treatment group and a placebo in the control group, and provided sufficient data to calculate an effect size were included. Inclusion criteria consisted of the following: randomized trials using an antibiotic in the treatment group and a placebo in the control group; subjects with acute bronchitis, no history of chronic lung disease, and pneumonia excluded by chest radiograph or clinical exam; therapy for at least 5 days; and the presentation of sufficient data to calculate the difference in efficacy between the treatment and the placebo as a continuous variable. doi = 10.1016/s0002-9343(99)00167-9 id = cord-349775-zwslhjju author = Brittain-Long, Robin title = Access to a polymerase chain reaction assay method targeting 13 respiratory viruses can reduce antibiotics: a randomised, controlled trial date = 2011-04-26 keywords = PCR; antibiotic; patient summary = The objective of this study was to evaluate whether access to a multiplex polymerase chain reaction (PCR) assay panel for etiologic diagnosis of acute respiratory tract infections (ARTIs) would have an impact on antibiotic prescription rate in primary care clinical settings. Acute respiratory tract infections (ARTIs) represent a major global health burden [1] , and viruses cause a large proportion of ARTIs. Distinguishing bacterial ARTIs that require antibiotic treatment from viral ARTIs not needing an antibiotic prescription can be difficult on clinical grounds alone and causes unnecessary use of antibiotics, with the highest rates occurring in the primary care setting [2, 3] . The present study was designed to evaluate whether access to a multiplex RT-PCR method targeting thirteen viruses would have an impact on antibiotic prescription rates for ARTI in a primary care setting. doi = 10.1186/1741-7015-9-44 id = cord-297125-la20vi9j author = Brower, Jennifer L. title = The Threat and Response to Infectious Diseases (Revised) date = 2016-08-01 keywords = CDC; HIV; President; States; United; antibiotic; disease; infectious; threat summary = In just the past year, the United States has been bombarded with headlines on the dangers of infectious diseases: "HIV ''Epidemic'' Triggered by Needle-Sharing Hits Scott County, Indiana [1] ;" "American with Ebola Now in Critical Condition [2] ;" "Seasonal Flu Vaccine Even Less Effective than Thought: CDC [3] ;" "''Superbug'' Outbreak at California Hospital, more than 160 Exposed [4] ;" "Deadly CRE Bugs Linked to Hard to Clean Medical Scopes [5] ;" "Painful Virus [Chikungunya] Sweeps Central America, Gains a Toehold in U.S. Many factors have reduced the number of new antibiotics approved in the United States each year as well as reduced domestic production including demanding Food and Drug Administration (FDA) regulations, the cost and time to market of development, the consolidation in the pharmaceutical industry, and the lack of financial impetus to produce and distribute antibiotics, which are generally used on a one-off basis versus drugs used to treat chronic conditions such as statins, Viagra, and allergy medications. doi = 10.1007/s00248-016-0806-9 id = cord-312417-li41ng7v author = Chowdhury, Moyukh title = Rural community perceptions of antibiotic access and understanding of antimicrobial resistance: qualitative evidence from the Health and Demographic Surveillance System site in Matlab, Bangladesh date = 2020-10-12 keywords = ABACUS; AMR; Bangladesh; Matlab; antibiotic summary = title: Rural community perceptions of antibiotic access and understanding of antimicrobial resistance: qualitative evidence from the Health and Demographic Surveillance System site in Matlab, Bangladesh OBJECTIVE: To explore factors and practices around access and use of antibiotics and understanding of antimicrobial resistance in rural communities in Bangladesh from a socio-cultural perspective. METHODS: This qualitative study comprises the second phase of the multi-country ABACUS (Antibiotic Access and Use) project in Matlab, Bangladesh. Multi-sectoral action is needed to confront the underlying social, economic, cultural and political drivers that impact on the access and use of antibiotic medicines in Bangladesh. The objective of this study is to explore factors and practices around access and use of antibiotics and understanding of antimicrobial resistance in rural communities in Bangladesh from a socio-cultural perspective. This study found that people in rural communities in Matlab were either not informed or knew little about appropriate access and use of antibiotic medicines. doi = 10.1080/16549716.2020.1824383 id = cord-252243-ua2w6xki author = Cooper, Emily title = Diagnosis and Management of UTI in Primary Care Settings—A Qualitative Study to Inform a Diagnostic Quick Reference Tool for Women Under 65 Years date = 2020-09-07 keywords = UTI; antibiotic; patient summary = Results: Staff were very aware of common UTI symptoms and nitrofurantoin as first-line treatment, but some were less aware about when to send a urine culture, second-line and non-antibiotic management, and did not probe for signs and symptoms to specifically exclude vaginal causes or pyelonephritis before prescribing. • Clearly outlines how to clinically assess someone with suspected UTI; • Includes prompts/considerations around differential diagnosis, pyelonephritis, and sepsis; • Clearly outlines the steps for clinical assessment of someone with suspected UTI and when a urine dipstick test or culture is needed; • Provides information on the sensitivity and specificity when using urine dipsticks to diagnose a UTI for women under 65 years; • Has been developed as an update to previous guidance; • Links to latest national guidance on antimicrobial prescribing for UTI management (developed since this study was conducted); • Links to UTI leaflets and resources for women under 65 years that explains evidenced-based prevention and self-care recommendations. doi = 10.3390/antibiotics9090581 id = cord-304972-aktfbriw author = Cots, Josep M. title = Recommendations for Management of Acute Pharyngitis in Adults date = 2015-06-30 keywords = GABHS; antibiotic; cause; patient summary = 4---7 In normal practice, a diagnosis is made based on clinical criteria (fever, tonsillar exudate, anterior cervical lymphadenopathy and no cough), which are of low sensitivity in predicting GABHS (49%---74%), and therefore the indication for the prescription of antibiotics increases as there are a great many false positives. Validity depends on the sample collection technique (false-negative results can be given when little material has been obtained), on the area from which it is collected (there is a better yield when collected from the tonsils and/or the wall posterior to the pharynx), on the culture procedure and conditions, on the probability of streptococcal infection (some authors have found a spectrum bias, so that the sensitivity of Strep A increases the higher the Centor criteria number presented by a patient), the presence of other germs in the pharynx (false-positive results can be given if the pharynx presents major growth of Staphylococcus aureus), on the use of tests which are past their expiry date, and on commercial brand. doi = 10.1016/j.otoeng.2015.05.003 id = cord-322915-zrjx31ev author = Demain, Arnold L title = Microbial drug discovery: 80 years of progress date = 2009-01-09 keywords = FDA; HIV; Streptomyces; antibiotic; cell; drug; gram; natural; new; product summary = Evidence of the importance of natural products in the discovery of leads for the development of drugs for the treatment of human diseases is provided by the fact that close to half of the best selling pharmaceuticals in 1991 were either natural products or their derivatives. In addition to the antibiotic-resistance problem, new families of anti-infective compounds are needed to enter the marketplace at regular intervals to tackle the new diseases caused by evolving pathogens. 28 Among the novel class of antimicrobial agents used in treating resistance to Gram-positive infections, we can also mention the cyclic lipopeptide antibiotic daptomycin produced by Streptomyces roseosporus. 44 Other applications include antitumor drugs, enzyme inhibitors, gastrointestinal motor stimulator agents, hypocholesterolemic drugs, ruminant growth stimulants, insecticides, herbicides, coccidiostats, antiparasitics vs coccidia, helminths and other pharmacological activities. Considering that animal health research and the development of new anti-infective product discovery have decreased, the discovery of new antibiotics has decreased over the past 15 years, with few new drug approvals. doi = 10.1038/ja.2008.16 id = cord-010012-1hrx1w8r author = Destache, Christopher J. title = Optimizing Economic Outcomes in Acute Exacerbations of Chronic Bronchitis date = 2012-01-17 keywords = AECB; antibiotic summary = The treatment of community‐acquired respiratory tract infections, such as acute exacerbations of chronic bronchitis (AECB), constitutes a huge socioeconomic burden. The treatment of community-acquired respiratory tract infections (RTIs), such as acute exacerbations of chronic bronchitis (AECB), constitutes a huge socioeconomic burden. Indeed, antibiotic treatment is associated with lower relapse rates, longer periods between exacerbations, shorter duration of symptoms, and reduced hospitalizations. However, studies of antibiotic therapy for AECB have failed to either account for differences among patients or examine the effect of increasing rates of antimicrobial resistance on clinical and economic outcomes. 22 It was concluded that this study found that in patients with COPD experiencing an AECB, the use of third-line antibiotics significantly reduced treatment failure rates and the need for hospitalization, while prolonging the time between AECB episodes.

R. title = The potential of anti‐infectives and immunomodulators as therapies for asthma and asthma exacerbations date = 2017-08-10 keywords = antibiotic; asthma; respiratory; study summary = Despite these important associations, the use of antiinfectives (antibiotics, antivirals, antifungals, vaccines) that specifically target known pathogens, or drugs that are based on or exploit microbe-host receptor interactions (toll-like receptor agonists, bacterial lysates) or are immunomodulators (vitamin D), and/or may work in part by altering our associated microbiology (probiotics) are, with the exception of severe asthma, seldom considered in asthma treatment, prevention and guidelines. Overall, antibiotic use is associated with asthma risk rather than protection at most stages of human development, including pregnancy, 10, 11 early life 12 and childhood, 13 although why this is so is a subject widely debated. 10 In retrospective studies, the association between antibiotic use and increased risk of asthma or wheezing in children is further confused due to the potential of reverse causation. Inhibiting virus replication through interfering with viral enzymes active within cells poses additional problems in drug discovery; however, several useful inhibitors for respiratory tract viruses have found their way into phase I/II clinical trials. doi = 10.1111/all.13257 id = cord-021158-075vh5jg author = Fortané, Nicolas title = Antimicrobial resistance: preventive approaches to the rescue?

Indeed, it is common to hear professional organizations or public authorities state that in order to reduce their economic dependence on antibiotic sales, vets must rethink their activity by favouring preventive approaches to animal health which would involve a diversified range of services and would contribute to placing vets in an advisory role with a holistic vision of livestock farming or even of the food supply chain (VetFuturs France 2018) . doi = 10.1007/s41130-019-00098-4 id = cord-009967-fyqc5bat author = Gleckman, Richard title = Cost‐Effective Antibiotic Prescribing date = 2012-01-24 keywords = antibiotic; infection; patient; therapy; treatment summary = Recent studies have confirmed the efficacy and reduced expense of oral antibiotics prescribed for selected children with osteomyelitis and septic arthritis.1"22 In 1973, it was reported that favorable results ensued when oral antibiotic therapy was prescribed for hospitalized patients with serious infectionsz3 Fourteen patients with osteomyelitis were treated successfully with oral cephalexin after they had received a short course of parenteral cephaloridine. Adults with disseminated gonococcal infection can be effectively treated with a one week program consisting initially of 2 million units of penicillin G administered every 4 hours followed by oral ampicillin or amoxicillin prescribed as 500 mg four times daily.34,35 Hospitalization is usually recommended to establish the diagnosis of disseminated gonococcal disease since misdiagnosis occurs not infrequently with this disorder.33 Selected patients can complete the oral regimens in an outpatient setting or, alternatively, they can be treated entirely without ho~pitalization.~~ Acceptable oral regimens consist of giving amoxicillin (500 mg four times daily), tetracycline (500 mg four times daily), or erythromycin (500 mg four times daily) for at least 7 days. doi = 10.1002/j.1875-9114.1983.tb03264.x id = cord-310474-hip7t0jx author = Hansford, Karl A. title = Nontraditional Antibiotics—Challenges and Triumphs date = 2020-04-09 keywords = antibiotic summary = Although the future potential of nontraditional therapies is viewed with cautious optimism, adequate resourcing will be critical to demonstrate clinical impact, especially when many of the translational criteria associated with direct-acting small molecule therapeutics will likely be incongruent with the nontraditional development pathway. The three review articles by Zurawski and McLendon [5] , Nikolich and Filippov [6] , and Ghose and Euler [7] give a superb timely survey of how monoclonal antibodies, bacteriophages and lysins, respectively, are currently being explored in the treatment of bacterial infections. Turning to small molecule therapeutics, Frei''s perspective on the untapped potential of metal complexes as antibiotics provides a compelling view that chemical classes often misconstrued as only being useful for certain applications should not be overlooked as potential sources of new chemotypes to fight bacterial infections [8] .

Similarly, bacteremias due to Staphylococcus aureus, Pseudomonas aeruginosa, and Clostridium species as well as candidemias are more frequently encountered in patients with acute leukemia who suffer from neutropenic enterocolitis or typhlitis, the most serious disturbance of the delicate balance between mucosal damage and microbial flora in the setting of prolonged exposure to antibiotics after intermediate or high-dose cytarabine chemotherapy.

In adults, influenza virus, rhinovirus, adenovirus, respiratory syncytial virus (RSV), human coronavirus, and parainfluenza virus cause infections with considerable morbidity and mortality [1, 3] , and in infants, RSV is the most common reason for RTIs among hospitalized patients [4] . In this study, we aimed to describe the viral etiology in influenza-like illness (ILI) in children and adults and to show the benefit of new rapid molecular respiratory tests (MRT) in decreasing inappropriate antibiotic use.

Taking two typical antibiotics, imipenem and carbapenem as example, the docked complex structures revealed that although the antibiotics adopted diverse conformations in the active site, the lactam motifs were positioned in the same orientation by coordinating with zinc ions tightly ( Figure 2C ), which suggested that the catalytic mechanisms were highly conserved among B1 subclass enzymes, as shown in Figure 3 .

The evidence set out in this paper suggests that, if combined with measures ensuring clean water and adequate sanitation, targeted hygiene practices in home and everyday life settings could make a significant contribution to tackling AMR through infection prevention and a consequential reduction in antibiotic prescribing. doi = 10.1016/j.ajic.2020.04.011 id = cord-018557-iuu38yes author = Mainous, Arch G. title = Upper Respiratory Infections and Acute Bronchitis date = 2009-09-10 keywords = acute; antibiotic; otitis; treatment summary = Treatment recommendations from the AAP/AAFP guidelines for the management of acute otitis media suggest that observation rather the initial use of antibiotics is appropriate depending on the child''s overall health, age, severity of illness, and likelihood that they can follow-up if necessary.

Beta-lactam antibiotics have been known for almost 80 years and their widespread use has created selection pressures on bacterial pathogens to resist their inhibitory actions. These investigators discovered that the resistant strain had acquired a new methylase gene that blocked the binding site for inhibition by aminoglycosides on a specifi c sequence on 16S ribosomal RNA. Mutations resulting in the loss of specifi c porins can occur in clinical isolates and determine increased resistance to beta-lactam antibiotics.

In conclusion, this study found the addition of molecular POCT testing to routine real-time PCR testing for respiratory viruses and atypical pathogens might help to reduce intravenous antibiotic use in LRTI patients without resulting in adverse outcomes. doi = 10.1016/j.cmi.2019.06.012 id = cord-333535-pzjj2wxc author = Smith, Geof title = Antimicrobial Decision Making for Enteric Diseases of Cattle date = 2015-02-20 keywords = antibiotic; calf; diarrhea summary = Despite the limited number of enteric diseases in adult cattle that would benefit from antimicrobial therapy, surveys indicate that diarrhea is a relatively common reason for the use of antibiotics. If Salmonella are the main target of antimicrobial therapy in adult cattle with diarrhea, drug selection should ideally be based on the results of susceptibility testing using bacterial strains recovered from that particular dairy or feedlot. Despite this importance, the United States Department of Agriculture Dairy 2007 study shows a preweaned Antimicrobial Decision Making heifer calf mortality rate of 8.7% and reports that only 40% of farms can supply an adequate number of replacements from their own herd. The investigators concluded that amoxicillin had a significant effect on disease by decreasing mortality and number of scouring days; however, treatment success could not be predicted by whether the E coli cultured from rectal swabs was susceptible or resistant to the antimicrobial being used. doi = 10.1016/j.cvfa.2014.11.004 id = cord-030184-5iv6qt7t author = Tan, Glorijoy Shi En title = Gut Microbiota Modulation: Implications for Infection Control and Antimicrobial Stewardship date = 2020-08-07 keywords = CDI; antibiotic; gut; microbiota summary = Fecal microbiota transplant has been found to be one of the most effective ways to regulate the gut microbiota dysbiosis in the setting of CDI [49] Fecal microbiota transplant has been studied in gut decolonization of MDRO, but has not conclusively been found to be effective [55, 56, 58] Selective oral decontamination and selective digestive decontamination with oral antibiotics has been evaluated as a means of reducing infections caused by endogenous MDRO, but has not been found to be efficacious [61] [62] [63] Restoration of the gut microbiota diversity through probiotics and prebiotics have some role in restoring gut diversity in specific diseases, such as necrotizing enterocolitis, acute infectious diarrhea and antibiotic-associated diarrhea [64] [65] [66] [67] [68] [69] Randomized controlled trials have shown positive effects on gut health by probiotics in a myriad of conditions, such as infectious and antibiotic-associated diarrhea (AAD), irritable bowel syndrome, and enterocolitis [64] . doi = 10.1007/s12325-020-01458-z id = cord-282628-6uoberfu author = Tiwari, Bhagyashree title = Future impacts and trends in treatment of hospital wastewater date = 2020-05-01 keywords = antibiotic; disease; emergence; human; pathogen; virus summary = The causative agent of most emerging infectious diseases is viruses; every year approximately more than two novel viral pathogens are identified, which can cause illness in a human. Factors for emergence include natural process (evolution of pathogen), infectious agents transfer from vertebrate to mammals, antimicrobial resistance (AMR), and climate change. The factors responsible for the emergence of infectious diseases such as (1) the evolution of new strain, (2) the introduction of a host to enzootic, (3) translocation of infected wildlife, (4) farming practices, and (5) others were provided. Due to emergence of antibiotic-resistant pathogens and unavoidable use of antibiotics, concomitant environmental perturbation caused by climate change might make the earth is not suitable for humans and other livings. Increasing resistance to antibiotics and the emergence of "superbugs" that are resistant to drugs of last resort have highlighted the great need for alternative treatments of bacterial disease. Furthermore, development of drug-resistant organisms and increased pathogen survival rate, only raising panic about the human, animal, and environmental health. doi = 10.1016/b978-0-12-819722-6.00017-1 id = cord-275700-tx4hirm4 author = Whiteside, James L title = Acute bronchitis: a review of diagnosis and evidence-based management date = 2002-06-30 keywords = acute; antibiotic; bronchitis summary = Because of the increasing bacterial resistance to antibiotics, the cost of prescription drugs, and the potential adverse reactions to them, the present management of acute bronchitis has important shortcomings. This definition highlights the first two steps for treatment: 1) identify patients who have chronic pulmonary disease or other coexisting medical illnesses such as congestive heart failure or immunosuppression and 2) appropriately rule out other causes of acute cough, such as pneumonia and sinusitis. For the patient who presents with acute onset of cough and no history of chronic pulmonary disease or evidence of other more serious illnesses, studies have consistently shown either no benefit or, at best, modest benefit from the use of antibiotics.

From 2009 to 2010, adults had the highest rate of inappropriate antibiotic use for acute respiratory tract infections (URTIs, influenza, and viral pneumonia), with 500 antibiotic prescriptions per 1000 ED visits for adults aged 20-64 years and 666 per 1000 visits for those aged > = 65 years [10] . In this study, we aim to develop prediction models based on local clinical and laboratory data to guide antibiotic prescribing for adult patients with uncomplicated URTI with the ultimate goal of deploying them as an evidencebased clinical decision support tool for routine practice.

This is despite the significantly poorer access to dentistry (only around 7,500 patients were seen at designated urgent dental centres [UDCs] across England) compared to May when the capacity of these centres increased and saw over 27,000 patients. 2 Antibiotics may have been used: • As a ''quick fix'' to avoid the life-time impact of an unnecessary extraction, in anticipation that AGPs might soon be permissible in general dental practices • Because dentists felt pressured by some patients for antibiotics, irrespective of their efficacy or appropriateness for treating toothache • Because of difficulties diagnosing a patient''s condition remotely prompting a ''just in case'' approach through concerns of life-threatening deterioration without treatment Finally, the NHS may have seen an influx in patients who might otherwise receive care privately, resulting in an increase in NHS dental prescriptions as, anecdotally, not all practices were open for telephone triage during April and May 2020. doi = 10.1038/s41415-020-2128-z id = cord-289382-bnl9i9oy author = Wright, Gerard D title = Q&A: Antibiotic resistance: where does it come from and what can we do about it? date = 2010-09-20 keywords = antibiotic; drug; resistance summary = • the spread of virulent MRSA (methicillin-resistant Staphylococcus aureus) in the community; • the rise of multi-drug resistant Neisseria gonorrhoea; • the emergence and global dissemination of multi-drug resistant Acinetobacter baumannii, Pseudomonas aerugi nosa, Klebsiella pneumoniae and Enterobacteriaceae; • the spread of extensively drug resistant Mycobacterium tuberculosis; • the development of resistance to the two newest antibiotics to be approved for clinical use -daptomycin and linezolid. Microbial natural products have evolved over millennia to interact with biological molecules, whereas the synthetic chemical libraries used in antibiotic drug-discovery screens were generally developed with a focus on eukaryotic drug-discovery campaigns, as noted earlier. Efforts to develop physical-property rules for antibiotics and to incorporate natural-product-like chemical complexity in libraries of synthetic chemicals will no doubt improve success in identifying new synthetic antibiotic leads. Furthermore, natural-product producing bacteria from non-soil environments are being investigated and these have already resulted in new chemical matter, suggesting that there is a fantastic wealth of untapped chemical diversity waiting to be discovered. doi = 10.1186/1741-7007-8-123 id = cord-027860-s97hdhh6 author = Zeimet, Anthony title = Infectious Diseases date = 2020-06-22 keywords = HBV; HCV; HIV; HSV; PPD; SOR; States; UTI; United; antibiotic; cause; infection; patient; treatment summary = Although common upper respiratory bacterial pathogens, such as Moraxella (Branhamella) catarrhalis, Streptococcus pneumoniae, and Haemophilus influenzae, may be isolated from patients with acute bronchitis, their relevance is questionable because these bacteria can be present in the respiratory tract of healthy individuals. In the treatment of Bordetella pertussis, early administration of a macrolide antibiotic and patient isolation will likely decrease coughing paroxysms and limit spread of disease (Braman, 2006) (SOR: A). Risk factors for Pseudomonas infection include severe structural lung disease (e.g., bronchiectasis) and recent antibiotic therapy, health care-associated exposures or stay in hospital (especially in the ICU). Patients who present with severe infection or whose infection is progressing despite empiric antibiotic therapy should be treated more aggressively; the treatment strategy should be based on results of appropriate Gram stain, culture, and drug susceptibility analysis. For suspected MRSA skin infections, oral treatment options include trimethoprim-sulfamethoxazole, clindamycin, and doxycycline of purulent material when performing incision and drainage in the event that the patient fails to improve and antibiotic coverage becomes necessary. doi = 10.1016/b978-1-4377-1160-8.10016-8 id = cord-011189-c0ytamge author = da Fonseca Pestana Ribeiro, Jose Mauro title = Less empiric broad-spectrum antibiotics is more in the ICU date = 2019-11-27 keywords = ICU; antibiotic summary = The real impact of MDRs on the outcomes of ICU patients is debatable, but despite this controversy, the incidence of MDRs is related to poor quality-of-care, as an expression of reduced compliance to hand hygiene [14] , and a high burden of antibiotic exposure [15] . De-escalation decreases the time of antibiotic use, but a short exposure still exists; in this way, a single antibiotic dose may be enough to treat severe infections such as Fig. 1 Two different mindsets in the decision making process to initiate antibiotics to critically ill patients who are getting worse.

In principle, the major high-level goals consist of optimizing the use of such drugs in health and agriculture and minimizing environmental contamination; sustaining the development of new classes of antimicrobials drugs and other medicines and making them affordable and accessible to all who need them; and much more effective application of infection control and prevention principles. These new agents are bound to change the paradigm for the treatment of infections caused by colistin-resistant Gram-negatives, but uncertainties are still likely to remain, including which agent to use, how to optimize dosing in to maximize efficacy and minimize toxicity as well as potential for development of resistance, and whether use of more than one agent would still be needed. doi = 10.1016/s0924-8579(17)30340-0
