RESUMEN
OBJECTIVES: With increasing global interest in hospital antimicrobial stewardship (AMS) programmes, there is a strong demand for core elements of AMS to be clearly defined on the basis of principles of effectiveness and affordability. To date, efforts to identify such core elements have been limited to Europe, Australia, and North America. The aim of this study was to develop a set of core elements and their related checklist items for AMS programmes that should be present in all hospitals worldwide, regardless of resource availability. METHODS: A literature review was performed by searching Medline and relevant websites to retrieve a list of core elements and items that could have global relevance. These core elements and items were evaluated by an international group of AMS experts using a structured modified Delphi consensus procedure, using two-phased online in-depth questionnaires. RESULTS: The literature review identified seven core elements and their related 29 checklist items from 48 references. Fifteen experts from 13 countries in six continents participated in the consensus procedure. Ultimately, all seven core elements were retained, as well as 28 of the initial checklist items plus one that was newly suggested, all with ≥80% agreement; 20 elements and items were rephrased. CONCLUSIONS: This consensus on core elements for hospital AMS programmes is relevant to both high- and low-to-middle-income countries and could facilitate the development of national AMS stewardship guidelines and adoption by healthcare settings worldwide.

KEY MESSAGES: There is a relative lack of confidence among GPs in the assessment and management of IBP vs. mechanical back pain. A simple screening tool for SpA, applicable in primary care urgently needs to be developed. It is reasonable for patients with symptoms suggestive of inflammatory back pain to be referred to secondary care without further investigations. The objective of this study was to assess current practice of our local general practitioners (GPs) in using clinical features, as well as radiological and laboratory investigations to assess patients with IBP. An online, observational questionnaire-based survey was done in 10 West Midlands CCGs including disparate geographical and socioeconomic areas. The survey consisted of 23 questions based on Calin, Berlin and ESSG Criteria for spondyloarthropathies. GPs were asked to rate the importance of a range of symptoms as indications of IBP IBP (10 point scale, range 1-10), and what their views were on which were the most important treatments for patients with suspected inflammatory back pain(4 point scale, range 1-4). The 4 most important symptoms for predicting inflammatory back pain according to our local cohort of GPs were 'morning stiffness' 'sleep disturbances caused by back pain' 'insidious onset' and 'age of onset' < 45. Among the treatment options, NSAIDs were ranked as the most important treatment option for IBP. DMARDS were rated as the next most important treatment option, ahead of physiotherapy and anti-TNF therapy. This study has highlighted relative lack of confidence among GPs in the assessment of IBP. Whether this reflects a need for education or poor performance of these questions in primary care populations requires further study.

BACKGROUND: There is an urgent need for improved estimations of the burden of tuberculosis (TB). OBJECTIVE: To develop a new quantitative method based on mathematical modelling, and to demonstrate its application to TB in India. DESIGN: We developed a simple model of TB transmission dynamics to estimate the annual incidence of TB disease from the annual risk of tuberculous infection and prevalence of smear-positive TB. We first compared model estimates for annual infections per smear-positive TB case using previous empirical estimates from China, Korea and the Philippines. We then applied the model to estimate TB incidence in India, stratified by urban and rural settings. RESULTS: Study model estimates show agreement with previous empirical estimates. Applied to India, the model suggests an annual incidence of smear-positive TB of 89.8 per 100 000 population (95%CI 56.8-156.3). Results show differences in urban and rural TB: while an urban TB case infects more individuals per year, a rural TB case remains infectious for appreciably longer, suggesting the need for interventions tailored to these different settings. CONCLUSIONS: Simple models of TB transmission, in conjunction with necessary data, can offer approaches to burden estimation that complement those currently being used.

In the last decade we have witnessed a dramatic increase in the proportion and absolute number of bacterial pathogens resistant to multiple antibacterial agents. Multidrug-resistant bacteria are currently considered as an emergent global disease and a major public health problem. The B-Debate meeting brought together renowned experts representing the main stakeholders (i.e. policy makers, public health authorities, regulatory agencies, pharmaceutical companies and the scientific community at large) to review the global threat of antibiotic resistance and come up with a coordinated set of strategies to fight antimicrobial resistance in a multifaceted approach. We summarize the views of the B-Debate participants regarding the current situation of antimicrobial resistance in animals and the food chain, within the community and the healthcare setting as well as the role of the environment and the development of novel diagnostic and therapeutic strategies, providing expert recommendations to tackle the global threat of antimicrobial resistance.
RESUMEN
CONTEXT: Antimicrobial use has been associated with increasing antimicrobial resistance. There is an urgent need for judicious use of antimicrobials. Informational feedback has been shown to result in changes in behavioural practices of physicians in certain healthcare settings. We conducted this study to see if the passive informational feedback can reduce in antimicrobial usage in a tertiary care centre. AIMS: The study was undertaken to evaluate if the feedback to clinicians on their own antibiotic prescription results in any change in their antibiotic prescription habits. SETTINGS AND DESIGN: The study was conducted at a tertiary care setting involving 33 units of different specialties. These units were split into 10 groups based on specialty and were allocated randomly to the control (16 units) and intervention (17 units) arms of the study. This study was a prospective intervention to assess the effect of prescribing feedback on clinical prescribing practices. MATERIALS AND METHODS: In the intervention arm, information on resistance rates and antibiotic-prescribing patterns was provided to all doctors. Behavioural change was assessed by comparing baseline prescribing rates of each unit with prescribing rates after the intervention. In the control arm, only information on monthly resistance rates was provided. STATISTICAL ANALYSIS: Change in the antimicrobial prescribing rates in the treatment group was assessed by using a Student's t-test. RESULTS: The mean antibiotic use for all the specialties was 189 DDDs/100BDs. The prospective intervention did not elicit any effect on the antibiotic prescribing practices of the physicians. Low prescribers continued to prescribe antibiotics at a low rate, and high prescribers continued to prescribe at a high rate. CONCLUSIONS: In view of unfavourable results of passive intervention in the above study, active intervention may be more effective.

RESUMEN
The declining effectiveness of antibiotics imposes potentially large health and economic burdens on societies. Quantifying the economic outcomes of antibiotic resistance effectively can help policy-makers and healthcare professionals to set priorities, but determining the actual effect of antibiotic resistance on clinical outcomes is a necessary first step. In this article, we review and discuss the contributions and limitations of studies that estimate the disease burden attributable to antibiotic resistance and studies that estimate the economic burden of resistance. We also consider other factors that are important in a comprehensive approach to evaluating the economic burden of antibiotic resistance.

The time relations of epileptic events have been studied in 3 sets of data: (I) counts of individual epileptiform discharges in twelve 48 h EEG recordings, (IIa) seizure calendars of 30 therapy-resistant outpatients participating in a drug trial, (IIb) seizure calendars of 10 mentally subnormal epileptic patients resident in a long-stay unit. The EEG data I were characterized most often by a Poisson distribution of intervals between discharges and the occurrence of marked periodicities, particularly at night. The periods of rhythmic nocturnal events ranged from 13 to 142 min and did not appear to correspond to the REM/non-REM cycle. In the seizure data IIa and b a Poisson distribution of intervals between events was found in half the patients. Periodicities occurred only in group IIa and did not correspond to weekly or monthly cycles. A stochastic process is considered to be the model which best fits these data.

Eighteen continuous 48 h monitoring studies are reported from 17 patients with epilepsy. The numbers of epileptiform discharges over corresponding epochs of the 2 days were significantly positively correlated in 16 studies. However, this was explicable by masking due to the sleep/wake cycle and when waking and sleep were considered separately a minority of studies showed significant correlations. The difference in total 24 h production of discharges between the 2 days ranged from 1.3 to 30.3%, mean 15.1%. The maximum discharge rate in 75% of the studies occurred during sleep; during waking the distribution of discharges was random. Even in the waking state the 0.5 h discharge rate was extremely variable and in few patients could a single 30 min epoch be regarded as a reliable sample of the mean rate over the waking day. The intervals between events showed a Poisson distribution during 9 days and 5 nights, but there was no within-patient consistency between the first and second 24 h period. The occurrence of discharges was periodic significantly more often at night than during the day, but the periodicities did not clearly correspond to the REM cycle. Discharges increased overall during sleep in 14 studies, were unchanged in 2 and decreased in 4. The time of occurrence of maximal discharge rate during sleep was consistent from night I to night II only in patients exhibiting generalized regular spike-wave activity but random in the others. A negative correlation between antiepileptic drug levels and discharge rate was rarely observed.
