Sexual violence during the war: towards an understanding of variation

This article focuses on sexual violence against civilians by the combatants. First, it resumes the variation patterns of violence form and extension throughout the different wartime situations. In particular, the absence of sexual violence in some conflicts and by some armed groups is here with documented. After discussing the methodological challenges to compile and analyze the information on sexual violence, it is argued that the topic deserves an extended comparative analysis since there is an ample enough variation across really well documented cases. An evaluation is made about whether the causal mechanisms identified in the literature (often implicit) explain the variation. In the conclusion, an analytical framework scheme is made for the study of sexual violence as part of the violence repertoires of the armed groups and also a suggestion is made about several research designs which can contribute to the academic understanding of sexual violence and other forms of violence.Este artículo se enfoca en la violencia sexual contra los civiles por parte de los combatientes. Primero, resume los patrones de variación en la forma y extensión de ésta a través de varias situaciones de guerra. En particular, se documenta la ausencia de violencia sexual en algunos conflictos y por parte de algunos grupos armados. Después de discutir los retos metodológicos para compilar y analizar la información sobre la violencia sexual, se argumenta que el tema amerita un amplio análisis comparativo debido a que ocurre una variación lo suficientemente amplia en casos muy bien documentados. Se evalúa si los mecanismos de causalidad identificados en la literatura (con frecuencia implícitamente) explican la variación. Como conclusión, se realiza un esquema del marco analítico para el estudio de la violencia sexual como parte de los repertorios de violencia de los grupos armados y se sugieren varias vías de investigación que pueden contribuir al entendimiento académico de la violencia sexual y de otras formas de violencia

The social processes of civil war: the wartime transformation of social networks

Little attention has been paid to the social processes of civil war —the transformations of social actors, structures, norms, and practices— that sometimes leave enduring legacies for the postwar period. In this article, I explore the changes wrought by six social processes: political mobilization, military socialization, polarization of social identities, militarization of local authority, transformation of gender roles, and fragmentation of the local political economy. Some of these social processes occur in peacetime, but war may radically change their pace, direction, or consequences, with perhaps irreversible effects. I trace the wide variation in these processes during the wars in four countries: Peru, El Salvador, Sri Lanka, and Sierra Leone. I analyze the effects of these processes as transformations into social networks. These processes reconfigure social networks in a variety of ways, creating new networks, dissolving some, and changing the structure of others.Se ha prestado poca atención a los procesos sociales de la guerra civil –la transformación de actores sociales, estructuras, normas, y prácticas- que a veces dejan legados duraderos para el periodo de la posguerra. En este artículo exploro los cambios originados por seis procesos sociales: la movilización política, la socialización militar, la polarización de identidades sociales, la militarización de la autoridad local, la transformación de los roles de género, y la fragmentación de la economía política local. Algunos de estos procesos sociales ocurren en tiempos de paz, pero la guerra puede cambiar radicalmente su ritmo, dirección, o consecuencias, con efectos tal vez irreversibles. Rastreo la amplia variación en estos procesos durante las guerras en cuatro países: Perú, El Salvador, Sri Lanka, y Sierra Leona. Analizo los efectos de estos procesos como transformaciones de las redes sociales que las reconfiguran de maneras variadas: crean nuevas redes, disuelven algunas, y cambian la estructura de otras

Genetic risk and a primary role for cell-mediated immune mechanisms in multiple sclerosis.

Multiple sclerosis is a common disease of the central nervous system in which the interplay between inflammatory and neurodegenerative processes typically results in intermittent neurological disturbance followed by progressive accumulation of disability. Epidemiological studies have shown that genetic factors are primarily responsible for the substantially increased frequency of the disease seen in the relatives of affected individuals, and systematic attempts to identify linkage in multiplex families have confirmed that variation within the major histocompatibility complex (MHC) exerts the greatest individual effect on risk. Modestly powered genome-wide association studies (GWAS) have enabled more than 20 additional risk loci to be identified and have shown that multiple variants exerting modest individual effects have a key role in disease susceptibility. Most of the genetic architecture underlying susceptibility to the disease remains to be defined and is anticipated to require the analysis of sample sizes that are beyond the numbers currently available to individual research groups. In a collaborative GWAS involving 9,772 cases of European descent collected by 23 research groups working in 15 different countries, we have replicated almost all of the previously suggested associations and identified at least a further 29 novel susceptibility loci. Within the MHC we have refined the identity of the HLA-DRB1 risk alleles and confirmed that variation in the HLA-A gene underlies the independent protective effect attributable to the class I region. Immunologically relevant genes are significantly overrepresented among those mapping close to the identified loci and particularly implicate T-helper-cell differentiation in the pathogenesis of multiple sclerosis

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.

Favorable prognostic value of SOCS2 and IGF-I in breast cancer

<p>Abstract</p> <p>Background</p> <p>Suppressor of cytokine signaling (SOCS) proteins comprise a protein family, which has initially been described as STAT induced inhibitors of the Jak/Stat pathway. Recent in vivo and in vitro studies suggest that SOCS proteins are also implicated in cancer. The STAT5 induced IGF-I acts as an endocrine and para/autocrine growth and differentiation factor in mammary gland development. Whereas high levels of circulating IGF-I have been associated with increased cancer risk, the role of autocrine acting IGF-I is less clear. The present study is aimed to elucidate the clinicopathological features associated with SOCS1, SOCS2, SOCS3, CIS and IGF-I expression in breast cancer.</p> <p>Methods</p> <p>We determined the mRNA expression levels of SOCS1, SOCS2, SOCS3, CIS and IGF-I in 89 primary breast cancers by reverse transcriptase PCR. SOCS2 protein expression was further evaluated by immuno-blot and immunohistochemistry.</p> <p>Results</p> <p>SOCS2 expression inversely correlated with histopathological grade and ER positive tumors exhibited higher SOCS2 levels. Patients with high SOCS2 expression lived significantly longer (108.7 vs. 77.7 months; P = 0.015) and high SOCS2 expression proved to be an independent predictor for good prognosis (HR = 0.45, 95% CI 0.23 – 0.91, P = 0.026). In analogy to SOCS2, high IGF-I expression was an independent predictor for good prognosis in the entire patient cohort. In the subgroup of patients with lymph-node negative disease, high IGF-I was a strong predictor for favorable outcome in terms of overall survival and relapse free survival (HR = 0.075, 95% CI 0.014 – 0.388, P = 0.002).</p> <p>Conclusion</p> <p>This is the first report on the favorable prognostic value of high SOCS2 expression in primary mammary carcinomas. Furthermore a strong association of high IGF-I expression levels with good prognosis was observed especially in lymph-node negative patients. Our results suggest that high expression of the STAT5 target genes SOCS2 and IGF-I is a feature of differentiated and less malignant tumors.</p

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
