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

Immunohistochemical evaluation of natural cases of encephalitic listeriosis in sheep

PubMedID: 30729816Listeriosis is an important public health problem in the world. It can cause abortion, encephalitis, septicemia, conjunctivitis and mastitis in ruminants. The development of central nervous system lesions is not fully understood in encephalitic listeriosis. We performed a retrospective analysis of 15 sheep with encephalitic listeriosis. Hyperemia and opacification of the meninges were common necropsy findings. Lesions generally were localized in the caudal part of the brain including the pons, medulla oblongata, thalamus and cerebellum. Microabscesses usually were found in the caudal brain and cerebellum, while perivascular infiltrates were found most often in other parts of the brain. Evidence of Listeria monocytogenes was detected immunohistochemically in the medulla oblongata, pons, thalamus and cerebellum. Prominent reactions for glial fibrillary acidic protein (GFAP), S100 protein, N-methyl-D-aspartate receptor-1 (NMDAR1) and inducible co-stimulatory protein (ICOS) were detected in the caudal brain, which indicates that these proteins may play roles in the pathogenesis of encephalitic listeriosis. © 2019, © 2019 The Biological Stain Commission.0129-NAP -11 0129-NAP-11Our study was supported by scientific Projects Commission of University of Mehmet Akif Ersoy (Project number: 0129-NAP -11).This work was supported by the scientific Projects Commission of University of Mehmet Akif Ersoy; [Project number: 0129-NAP-11]

Right Ventricular Functional Improvement after Pulmonary Rehabilitation Program in Patients with COPD Determined by Speckle Tracking Echocardioga araphy

Abstract Background: Although right ventricular (RV) dysfunction in pulmonary diseases has been associated with increased morbidity, tools for RV dysfunction identification are not well defined. Objective: The aim of this study was to evaluate the magnitude of RV dysfunction by means of speckle tracking echocardiography (STE) in patients with chronic obstructive pulmonary disease (COPD) and to investigate whether STE could be used as an index of RV improvement after a pulmonary rehabilitation (PR) program. Methods: Forty-six patients with COPD undergoing PR program and 32 age-sex matched healthy subjects were enrolled. RV function was evaluated at admission and after PR program by conventional two-dimensional echocardiography (2DE) and STE. In addition, exercise tolerance of subjects was evaluated using the six-minute walk test (6MWT). Results: COPD patients had worse RV function according to STE and 2DE as well. STE was more sensitive than conventional 2DE in determining RV improvement after PR program - RV global longitudinal strain (LS): 20.4 ± 2.4% vs. 21.9 ± 2.9% p < 0.001 and RV free wall LS: 18.1 ± 3.4% vs. 22.9 ± 3.7%, p < 0.001). RV free wall LS was directly related to distance walked at baseline 6MWT (r = 0.58, p < 0.001) and to the change in the 6MWT distance (6MWTD ∆) (r = 0.41, p = 0.04). Conclusions: We conclude that STE might be as effective as 2DE for evaluation of global and regional RV functions. STE may become an important tool for assessment and follow-up of COPD patients undergoing PR program to determine the relationship between RV function and exercise tolerance

Interobserver reproducibility of tumor-infiltrating lymphocyte evaluations in breast cancer

Aim: Tumor-infiltrating lymphocytes (TILs) have a prognostic value in breast cancer (BC); however, because of the lack of standard evaluation methods, we aimed to assess the interobserver agreement of stromal TILs (sTILs) and intratumoral TILs (iTILs) as well as the effect of hot spot areas and molecular subtyping on the overall agreement. Methods: The study consisted of 121 haematoxylin and eosin (H and E)-stained slides of invasive BC samples obtained from the pathology archives. The TIL assessment was based on the International TIL Working Group recommendations for the percentage of sTILs and was conducted by four pathologists. The percentage of iTILs, the number of lymphocytes in hot spot areas (iTILs-HS), and the overall interobserver agreement for the molecular subtypes were evaluated. The interclass correlation coefficient (ICC) was used to assess interobserver agreement among the four pathologists. Results: The ICC score among the observers for the sTIL percentages was 0.74, and the individual ICC values for each molecular subtype were 0.55, 0.88, and 0.79 for luminal, HER2-positive, and triple-negative tumors, respectively. The compliance value for the iTILs was 0.29 (95% confidence interval (CI) = 0.06–0.48], whereas the compliance value for the iTILs-HS was 0.63 (95% CI = 0.49–0.71). The compliance values for the iTILs-HS subtypes were 0.72, 0.43, and 0.55 for luminal, HER2-positive, and triple-negative tumors, respectively. Conclusion: The IWTILG recommendations are reproducible and reliable. The interobserver agreement of the sTIL percentages was considerably higher for the triple-negative and HER2-positive cases than the luminal cases, whereas the interobserver agreement for the assessment of iTILs-HS in tumors was higher for the luminal subtype

Pitfalls of using the ILO classification for silicosis compensation claims

Background The International Labour Organization (ILO) Classification of Radiographs of Pneumoconioses is used as the primary tool to determine compensation for pneumoconiosis in Turkey. Aims We aimed to evaluate how the ILO classification applied, but obtaining chest radiographs in the workplace for screening until the completion of compensation claim files by the referral centres, based on the ILO reading. Methods The study included 320 digital chest radiographs previously taken for screening from eight different ceramic factories and having finalised claim files by referral centres. We used an expert reference panel consisting of five ILO readers to re-evaluate all the radiographs independently using ILO standard films and reached a conclusion based on the agreement among at least three readers. The evaluation primarily included technical quality and silicosis diagnosis with an ILO 1/0 or above small profusion. The results were compared with previous findings. Results Sixty-three (20%) chest radiographs were unacceptable for classification purposes according to the ILO technical quality grades. Among the remaining 257 chest radiographs, we diagnosed 103 with silicosis (40%), while the referral centres diagnosed 182 (71%). A discrepancy was found between our results and previous evaluations. We diagnosed silicosis in 50% and 17% of the previous silicosis and normal evaluations, respectively. Conclusions Our findings suggest that the use of the ILO classification for compensation claims may be problematic due to the way of its implementation in Turkey in addition to its subjectivity.Turkish Thoracic Society (TTS)The study was funded by Turkish Thoracic Society (TTS).

The evaluation of disease awareness, caregiver burden, and workday loss in caregivers of COPD patients

Background/aim: Our aim is to determine the caregiver burden of chronic obstructive lung disease (COPD) patient's caregivers, and to determine whether there is a workday loss. Materials and methods: 252 COPD patients and their caregivers were included. Disease information of the patients were recorded and a questionnaire was applied. Socio-demographic characteristics of the caregivers were recorded and a questionnaire consisting of 24 questions including COPD disease, treatment and loss of working days, and the Zarit Scale were used. Results: 128(50.8%) of the patients according to GOLD were group-D, 97(38.5%) of the patient's relatives were working, 62(24.7%) were not able to go to work for 1-14 days, and 125(57.1%) spent outside the home from 1-14 nights, because those accompanied to patients. In univariate analysis were detected modified medical research council (mMRC) (p < 0.001), CAT (p < 0.001), the number of comorbidities of patients (p = 0.027), forced expiratory volume in 1 FEV1cc (p = 0.009), FEV1% (p < 0.001), the presence of long term oxygen therapy (LTOT), and the number of comorbidities of the patient's relatives (p = 0.06) increased the care load. In multiple linear regression analysis, age (p = 0.03), COPD assessment test (CAT) score (p = 0.001), FEV1% (<0.068) and the number of comorbidities of patients (p = 0.01) and the number of comorbidities of caregivers (p = 0.003) increased the caregiving burden. Conclusion: In COPD increases caregiving burden. This burden is greater in symptomatic patients and when comorbidities are present. Psychosocial and legal regulations should be investigated and solutions should be produced for the caregivers of COPD patients
