Inappropriate use and overuse of antibiotics are among the most important factors in resistance development, and effective antibiotic stewardship measures are needed to optimize outcomes. Selection of appropriate antimicrobials relies on accurate and timely antimicrobial susceptibility testing. However, the availability of clinical breakpoints and in vitro susceptibility testing often lags behind regulatory approval by several years for new antimicrobials. A Working Group of clinical/medical microbiologists from Brazil, Canada, Mexico, Saudi Arabia, Russia and the UK recently examined issues surrounding antimicrobial susceptibility testing for novel antibiotics...

Mycoplasma pneumoniae (M. pneumoniae) is an important pathogen of neonatal acquired pneumonia in newborns. Rapid and accurate diagnosis of M. pneumoniae infection is critical because timely antibiotic therapy can reduce drug overuse and prevent the development of bacterial resistance. Anti-M. pneumoniae immunoglobulin M (IgM) is an indicator of early infection that can persist for several months. Studies have shown that anti-M. pneumoniae IgA in adults is a reliable indicator of early M. pneumoniae infection...

BACKGROUND: Reducing antibiotics overuse in animal agriculture is one key in combat against the spread of antibiotic resistance. Probiotics are a potential replacement of antibiotics in animal feed; however, it is not clear whether and how probiotics and antibiotics differ in impact on physiology and microbial ecology of host animals. RESULTS: Host phenotype and fecal microbiota of broilers with either antibiotics or probiotics as feed additive were simultaneously sampled at four time points from birth to slaughter and then compared...

Importance: Pneumonia is a leading cause of morbidity and mortality in children. It is important to identify the clinical symptoms and physical examination findings associated with pneumonia to improve timely diagnosis, prevent significant morbidity, and limit antibiotic overuse. Objective: To systematically review the accuracy of symptoms and physical examination findings in identifying children with radiographic pneumonia. Data Sources and Study Selection: MEDLINE and Embase (1956 to May 2017) were searched, along with reference lists from retrieved articles, to identify diagnostic studies of pediatric pneumonia across a broad age range that had to include children younger than age 5 years (although some studies enrolled children up to age 19 years); 3644 unique articles were identified, of which 23 met inclusion criteria...

This volume of Periodontology 2000 represents the 25th anniversary of the Journal, and uses the occasion to assess important advancements in periodontology over the past quarter-century as well as the hurdles that remain. Periodontitis is defined by pathologic loss of the periodontal ligament and alveolar bone. The disease involves complex dynamic interactions among active herpesviruses, specific bacterial pathogens and destructive immune responses. Periodontal diagnostics is currently based on clinical rather than etiologic criteria, and provides limited therapeutic guidance...

BACKGROUND: Using antibiotics appropriately is critical to slow spread of antibiotic resistance, a major public health problem. Children, especially young children, receive more antibiotics than other age groups. Our objective was to describe antibiotic use in children in the United States (US) and use of azithromycin, which is recommended infrequently for pediatric conditions. METHODS: We used QuintilesIMS Xponent 2013 data to calculate the number and rate of oral antibiotic prescriptions for children by age (0-2, 3-9 and 10-19 years) and agent...

Overuse of broad-spectrum antibiotics in outpatient pediatrics remains a significant issue and there is limited evidence on how to effectively implement outpatient stewardship interventions. This study examines the relationship between readiness to change and modifiable factors affecting success of a primary care network antibiotic stewardship intervention. A survey designed to measure readiness to accept a health care innovation was administered to 209 clinicians. Practices were split in half into "high" versus "low" readiness to change...

Microbiological cultures provide essential information to guide the antibiotic therapy. However, their results might be misleading for physicians and drive useless treatment, sometimes harmful for patients. Recommendations highlight the importance of clinical signs in order to take into account the pre-test probability when interpreting the results. This combination will improve the predictive value of microbiological tests. The sampling strategy is also important to avoid an overuse of these tests but also misleading results through a reduction of contaminants...

Community acquired pneumonia remains a common cause of morbidity and mortality. Usually, the causal organism is not identified and treatment remains empiric. Recent computed tomography and magnetic resonance imaging studies have challenged the accuracy of the clinical diagnosis of pneumonia, and epidemiologic studies are changing our perspective of what causes community acquired pneumonia, especially the role of viral pathogens and the frequent finding of multiple pathogens. The past decade has seen increasing overuse of empiric coverage of meticillin resistant Staphylococcus aureus and antibiotic resistant Gram negative pathogens owing to inappropriate application of guidelines for healthcare associated pneumonia...

BACKGROUND: The World Health Organisation (WHO) recommends parasitological diagnosis of malaria before treatment, but use of malaria rapid diagnostic tests (mRDTs) by community health workers (CHWs) has not been fully tested within health services in south and central Asia. mRDTs could allow CHWs to diagnose malaria accurately, improving treatment of febrile illness. METHODS: A cluster randomised trial in community health services was undertaken in Afghanistan. The primary outcome was the proportion of suspected malaria cases correctly treated for polymerase chain reaction (PCR)-confirmed malaria and PCR negative cases receiving no antimalarial drugs measured at the level of the patient...

INTRODUCTION: The risk of post-procedural urinary tract infection (ppUTI) after retrograde urethrogram (RUG) has not been well quantified. Prophylactic antibiotics may reduce the risk, but must be weighed against the risks of antibiotic resistance. Prior research has shown that this risk is variable after voiding cystourethrogram (0-42% reported ppUTI rate) and appears to be low after urodynamics (0-4.8%) but this risk has not been well documented for patients undergoing RUG. OBJECTIVE: We aimed to (1) describe the rate of ppUTI after RUG, and (2) examine factors associated with use of antibiotics at the time of RUG...
