Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

UCI manejo y mantenimiento del potencial donante de órganos y tejidos

Organ transplantation in recent years has become a very important medical procedure in the treatment of terminally ill patients, considered as a vital form of replacement for organs in irreversible failure. In Latin American countries, the donor index is lower compared to those countries where organ donation is entrenched. In this sense, because there is a marked shortage of available organs, proper and timely management of the potential donor is necessary, who is the patient who will donate an organ. The intensivist doctor plays a crucial role in turning a potential patient into a real donor, said patient must have a Glasgow scale (GCS) lower than 7, with severe neurological dam-age, ventilatory support, hemodynamic support and in which it has already been diagnosed brain death. The following article reviews the identification of possible organ donors and pathophysiological changes around brain death, with special emphasis on the management of the organ donor in intensive care. With a greater awareness of the problems of donor management and the application of a rational physiological system where the number of functional organs for transplantation can be increased.El trasplante de órganos durante los últimos años, se ha convertido en un procedimiento médico de gran importancia en el tratamiento de pacientes que se encuentran en etapa terminal, considerado como una forma vital de reemplazo para órganos en falla irreversible. En los países de Latinoamérica, el índice de donantes es inferior comparado con aquellos países en donde la donación de órganos se en-cuentra arraigada. En tal sentido, debido a que existe una escasez marcada de órganos disponibles, es necesario un manejo adecuado y oportuno del potencial donante quien es el paciente que donará algún órgano. El médico intensivista juega un papel crucial al convertir un paciente potencial en un donante real, dicho paciente debe tener una escala de Glasgow (GCS) menor a 7, con un daño neurológico severo, soporte ventilatorio, soporte hemodinámico y en el que ya se ha diagnosticado muerte encefálica. El siguiente articulo revisa la identificación de posibles donantes de órganos y cambios fisiopatológicos en torno a la muerte encefálica, con especial énfasis en el ma-nejo del donante de órganos en cuidados intensivos Con una mayor conciencia de los problemas de gestión de donantes y la aplicación de un sistema fisiológico racional donde se pueda aumentar el número de órganos funcionales para el trasplant

Anquilosis de la articulación temporomandibular

Introduction: it is of interest for physicians and specialist’s knowledge about the inability of the opening of the oral cavity due to coalitions between the bone and fibrous elements in the glenoid region. Objective: to review the literature on the characteristics of this pathology. Development: in the first quarter of 2006, in order to perform a non-exhaustive literature review to locate the available information on ankylosis of the temporomandibular joint, a literature search was carried out in Scielo, Medline, Isi Web of Knowlegde and Dialnet, searching as key words: ankylosis (ankylosis) and temporomandibular joint (temporomandibular joint). In addition to the computerized search, a manual search was made among the references of the selected studies. Conclusions: the temporomandibular ankylosis is a complex clinical entity, usually annoying for patients given the impossibility of feeding and nourishing adequately, in addition to the deformities that from the aesthetic point of view affects the psychological sphere of the people afflicted. Its treatment is difficult, nevertheless, an adequate attention minimizes the consequences of the complications that can appear as a result of the surgical technique or other factors not related to it. It is recognized that an identification and timely treatment of the problem can favor the good results of medical behavior and the rapid integration of the patient into society.Introducción: resulta de interés para médicos y especialistas el conocimiento sobre la incapacidad de la apertura de la cavidad oral debido a coaliciones entre los elementos óseos y fibrosos en la región glenoidea.
