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

Conductive education: A functional skills program for children with cerebral palsy
Conductive education (CE) is an educational approach for children with cerebral palsy. This paper describes the history of conductive education, and the characteristics of current programs that exist in many countries. The underlying principles and the unique techniques used in CE programs are described. These include the role of the conductor or class leader; facilitations (teaching strategies) known as rhythmic intention, task series, and described equipment; and the structured program. The importance of the group setting and the impact on motivation, and the development of self-efficacy within each child are described. The perspective of children and families who pursue CE is discussed. Existing evidence evaluating CE is summarized and recommendations for expanding the evidence base are made
Janus kinases and STAT family transcription factors: their role in the function and development of lymphoid cells
Cytokines are a diverse group of secreted factors
regulating cellular growth and differentiation.
Knowledge of cytokine signaling has exponentially
increased over the past few years. This
chapter focuses on only two structurally related
families of cytokine receptors, Type I and Type
II receptor families, since their receptor phosphorylation
leads to the activation of the Stat
family of transcription factors. Members of these
two receptor families have no intrinsic tyrosine
kinase activity and utilize Janus kinases (Jaks)
to initiate intracellular signaling. Type I receptors
bind hormones such as erythropoietin,
thrombopoietin, prolactin, growth hormone,
and specific interleukins, while Type II receptors
bind interferons (IFN). The structure and function
of various Jaks and Stats are the focus of
this review; the latter in particular are emphasized
in accordance with the transcription factor
theme of this book. Since many interleukins are
important in lymphoid development and immunoregulation,
the critical roles that Jaks and
Stats play in cytokine signaling may best be
illustrated in the context of lessons from human
disorders resulting from Jak mutations and the
study of Jak/Stat deficient mice. The space constraint
in this review makes citation of all of the
studies contributing to the understanding of
Jaks and Stats an impossible task. Hence,
readers interested in more information are directed
to some excellent reviews on this subject:
Aringer et al., 1999; Bach et al., 1997; Baird et
al., 1999; Carter-Su and Smit, 1998; Darnell et
al., 1994; Hoey and Grusby, 1999; Ihle, 1995;
Ihle et al., 1998; Leonard and O’Shea, 1998;
O’Shea, 1997.
An important caveat should be made first,
however. The fact that much work has focused
on the role of Jaks and Stats in cytokine signaling
has led to the notion of a ‘‘Jak-Stat’’ pathway.
While it has been useful to think of signaling in
these terms and genetic data on Drosophila can
be interpreted as a linear pathway, such a simplistic
view of mammalian Jak-Stat systems can be
misleading, as is elaborated below
