This edition features an overview chapter that highlights some of the major changes in society since Social Trends was first published. The UK has an ageing population, and growth in the minority ethnic population has resulted in a more diverse society. Household income has risen over the past 35 years, although income inequality has widened. Life expectancy has also increased but so have the number of years that we can expect to live in poor health or with a disability. Technology has transformed many of our lives and our dependence on the car is greater than ever.

London is the most ethnically diverse city in the UK. Census 2001 population figures suggest that: 40% of Londoners belong to a minority ethnic group, including the White Other and White Irish groups. The White Other (8%), Indian (6%), Black African (5%) and Black Caribbean (5%) groups are the largest in London. With the exception of the Pakistani group, London has the largest population from all ethnic minority groups out of all regions of England. There are wide differences in the proportion of the population from an ethnic minority group in different London boroughs, ranging from 71% in Brent to 8% in Havering.

This report arises from a project commissioned by the Department of Health's Equality and Human Rights Group to produce an evidence-based review with a national perspective that addresses (i) ethnic differentials in health and healthcare and (ii) evidence of effective NHS and other action, including seective examples of good practice to illustrate each area. Rather than aiming for comprehensive coverage, the Department suggested a document that focuses on selective topics and population health priorities drawn from the NHS plan, existing and developing National Service Frameworks, and other policy documents and which, collectively, are encompassed in the NHS's 10-point Race Equality Action Plan. The authors were not asked to review the evidence on other key areas (such ashypertension, stroke, disability, etc.), ethnic disparities in the wider determinants of health, and on some specific groups such as Gypsy Travellers and refugees and asylum seekers. Some of these topics are covered in other reviews.

The Commonwealth Immigrants Act of 1962 and the Commonwealth Act of 1968 restricted the rights of citizens from the Commonwealth of Nation countries to migrate to the UK by only permitting those with government issued employment vouchers to settle in the UK. As a reaction to racial violence at that time, the government established the Commission for Racial Equality in 1976. By the 1980's the UK immigration policy was marked by two strands: strict controls on entry and protection of ethnic minority rights. The UK integration system has focused mainly on the integration of ethnic minorities. In February 2008, due to the increasing number of immigrants moving to the UK, the UK reformed its integration system by introducing a point system, in order to restrict immigration focusing especially on labour migration.

Irish Travellers are an indigenous minority who, according to historical evidence, have been part of Irish society for centuries. They have a long shared history, value system, language, customs and traditions that make them a group recognised by themselves and others as distinct. This distinctive life-style and culture, based on a nomadic tradition, sets them apart from the settled population. The history of the Traveller community includes a struggle to uphold their distinct cultural identity and to maintain a nomadic way of life. For the purposes of this report it is accepted that Travellers have shared a nomadic tradition and a means of communication, beliefs, values and practices distinct from the majority culture.

This third and final report of the CEMACH national diabetes programme comes at an important time in the national drive to improve services for women with diabetes in pregnancy. The National Service Framework (NSF) for Diabetes requires the NHS to develop, implement and monitor policies that seek to empower and support women with diabetes to optimise the outcomes of their pregnancy. The CEMACH report shows that, whilst progress has been made in improving services for women with diabetes and their babies, there is much still to be done to meet the standards recommended by the NSF. Too many women continue to be poorly prepared for pregnancy in the critical areas of glycaemic control and folic acid supplementation. The report underlines the need for an increased focus on diabetes preconception care services and the development of strategies to educate women with diabetes of childbearing age. The growing proportion of women with type 2 diabetes during pregnancy, many of whom are from minority ethnic groups, presents an additional challenge for health services in developing responsive and accessible services.This CEMACH report has identifi ed several areas of good clinical practice during pregnancy in women with pre-existing diabetes. However, there continue to be areas where there is room for improvement, including antenatal fetal surveillance, glycaemic control during labour and delivery and postnatal diabetes care. The National Institute for Health and Clinical Excellence (NICE) is currently in the fi nal stages of development of its new guideline for the management of diabetes in pregnancy. This guideline, when taken together with the CEMACH report, will provide local health services with an unprecedented wealth of material on which to base their development of improved services for women with diabetes in pregnancy.��

Le neuroblastome (NB) est la tumeur maligne solide extra-crânienne la plus fréquente chez le jeune enfant. L'évolution clinique est très hétérogène, et les NBs de haut risque échappent encore aux traitements les plus agressifs. Diverses études ont montré que les chimiokines et leurs récepteurs, particulièrement l'axe CXCR4/CXCL12, sont impliqués dans la progression tumorale. Dans le NB, l'expression de CXCR4 est corrélée à un pronostic défavorable. De récentes études ont identifié l'expression d'un autre récepteur, CXCR7, présentant une forte affinité pour le ligand CXCL12. Cependant, son implication potentielle dans l'agressivité des NBs reste encore inconnue. Notre étude a pour objectif d'analyser le rôle de CXCR7 dans le comportement malin du NB, et son influence sur la fonctionnalité de l'axe CXCR4/CXCL12. Les profils d'expression de CXCR7 et CXCL12 ont d'abord été évalués sur un large échantillonnage de tissus de NB, incluant des tissus de tumeurs primaires et de métastases, provenant de 156 patients. CXCL12 est fortement détecté dans les vaisseaux et le stroma des tumeurs. Contrairement à CXCR4, CXCR7 n'est que très faiblement exprimé par les tumeurs indifférenciées. Néanmoins, l'expression de CXCR7 augmente dans les tumeurs matures, et se trouve spécifiquement associée aux cellules neurales différentiées, telles que les cellules ganglionnaires. L'expression de CXCR7 est faiblement détectée dans un nombre réduit de lignées de NB, mais peut-être induite suite à des traitements avec des agents de différenciation in vitro. La surexpression de CXCR7, CXCR4 et une combinaison des deux récepteurs dans les lignées IGR-NB8 et SH-SY5Y a permis l'analyse de leur fonction respective. En réponse à leur ligand commun, chaque récepteur induit l'activation de la voie ERK 1/2, mais pas celle de la voie Akt. Contrairement à CXCR4, l'expression exogène de CXCR7 réduit fortement la prolifération des cellules de NB in vitro, et in vivo dans un modèle d'injection sous-cutanée de. souris immunodéprimées. CXCR7 altère également la migration des cellules induite par l'axe CXCR4/CXCL12. De plus, l'utilisation d'un modèle orthotopique murin a démontré que la croissance tumorale induite par CXCR4 peut être fortement retardée lorsque les deux récepteurs sont co-exprimés dans les cellules de NB. Aucune induction de métastases n'a pu être observée dans ce modèle. Cette étude a permis d'identifier un profil d'expression opposé et des rôles distincts pour CXCR7 et CXCR4 dans le NB. En effet, contrairement à CXCR4, CXCR7 présente des propriétés non tumorigéniques et peut être associé au processus de différenciation du NB. De plus, nos analyses suggèrent que CXCR7 peut réguler les mécanismes induits par CXCR4. Ces données ouvrent donc de nouvelles perspectives de recherche quant au rôle de l'axe CXCR7/CXCR4/CXCL12 dans la biologie des NBs. - Neuroblastoma (NB) is a typical childhood and heterogeneous neoplasm for which efficient targeted therapy for high-risk tumours is not yet identified. The chemokine CXCL12, and its receptors CXCR4 and CXCR7 have been involved in tumour progression and dissemination in various cancer models. In the context of NB, CXCR4 expression is associated to undifferentiated tumours and poor prognosis, while the role of CXCR7, the recently identified second CXCL12 receptor, has not yet been elucidated. In this report, CXCR7 and CXCL12 expression were evaluated using a tissue micro-array (TMA) including 156 primary and 56 metastatic NB tissues. CXCL12 was found to be highly associated to NB vascular and stromal structures. In opposite to the CXCR4 expression pattern, the neural-associated CXCR7 expression was extremely low in undifferentiated tumours, while its expression increased in maturated tissues and was specifically associated to the differentiated neural tumour cells. As determined by RT-PCR, CXCR7 expression was only found in a minority of NB cell lines. Moreover, its expression in two CXCR7-negative NB cell lines was further induce upon treatment with differentiation agents in vitro. The relative roles of the two CXCL12 receptors was further assessed by overexpressing individual CXCR7 or CXCR4 receptors, or a combination of both, in the IGR-NB8 and SH-SY5Y NB cell lines. In vitro functional analyses indicated that, in response to their common ligand, both receptors induced activation of ERK 1/2 cascade, but not Akt signaling pathway. CXCR7 strongly reduced in vitro growth, in contrast to CXCR4. Sub-cutaneous implantations of CXCR7-expressing NB cells showed that CXCR7 also drastically reduced in vivo growth. Moreover, CXCR7 impaired CXCR4-mediated chemotaxis, and altered CXCR4-mediated growth when CXCR4/CXCR7-expressing NB cells were engrafted orthotopically in mouse adrenal gland, a CXCL12-producing environment. In such model, CXCR7 alone, or in association with CXCR4, did not induce NB cell metastatic dissemination. In conclusion, the CXCL12 receptors, CXCR7 and CXCR4, revealed opposite expression patterns and distinct functional roles in NB. While CXCR4 favours NB growth and chemotaxis, CXCR7 elicits anti-tumorigenic properties and may be associated with NB differentiation. Importantly, CXCR7 may act as a negative modulator of CXCR4 signaling, further opening new research perspectives for the role of the global CXCR7/CXCR4/CXCL12 axis in NB.

Malnutrition, a risk factor for osteoporotic fractures, is frequent in elderly people and, is underdiagnosed and undertreated. There are only few studies on the nutritional status of elderly people in Europe. The Mini Nutritional Assessment (MNA) is a non invasive and validated questionnaire to evaluate nutritional status in elderly people, classified in three groups: 1 degree score < 17: malnourished, 2 degrees score >17 and < 24: at risk of malnutrition, 3 degrees score >24: well-nourished, with a maximum of 30 points. Quantitative ultrasound of bone (QUS) is a method for assessing quality of bone which can be easily performed in nursing homes. Therefore, these two tests allowed to study the relationships between nutritional status and ultrasonic parameters of bone in 78 institutionalized women aged 86 +/- 6 years, living in 11 nursing homes around Lausanne (Switzerland). All were assessed by the MNA, had a measurement of the tricipital skin fold and of the grip strength. Functional status was evaluated by the scale "Activity of Daily Living" (ADL), and serum albumin level was measured when permitted. All had QUS of the calcaneus (with an Achilles, GE Lunar). The measured parameters are the Broadband Ultrasound Attenuation (BUA), attenuation of a band of ultrasonic frequencies through the medium, expressed in dB/MHz, and the Speed of Sound (SOS), speed of the ultrasounds through the medium, expressed in m/s. A third parameter, the stiffness index (SI), expressed as a percentage of the values obtained by the manufacturer in a young population and derived from BUA and SOS, was calculated automatically : SI = (0.67xBUA) + (0.28xSOS) - 420, expressed in percent compared to a young adult population (%YA). Fifteen percent of the women were undernourished and 58% were at risk of malnutrition. As expected, compared with the well-nourished minority, undernourished subjects had significant lower body mass index (BMI), tricipital skin fold (TSF), ADL score and albumin level (p < 0,01). The subjects "at risk of malnutrition" had significant lower BMI, ADL score (p < 0.01), tricipital skin fold and serum albumin (p < 0.05). Ultrasound parameters were low independently of the nutritional status. MNA score correlated significantly with tricipital skin fold (r = 0.508, p < 0.01), ADL (r = 0.538, p < 0.01) and albumin serum level (r = 0.409, p = 0.01). There was a trend for a correlation between the MNA and the ultrasound parameter BUA (r = 0.207, p = 0.07), whereas no correlation was found with SOS and SI. A multivariate analysis showed that tricipital skin fold and ADL explained 61% of the variance of the MNA. In conclusion, using simple and non invasive methods, this study showed that malnutrition and osteoporosis are frequent in institutionalized elderly persons in our country, and the ultrasound parameters are influenced by many others factors in addition to nutrition, especially at this age and in elderly residents of nursing homes.

C(4) photosynthesis is an adaptation over the classical C(3) pathway that has evolved multiple times independently. These convergences are accompanied by strong variations among the independent C(4) lineages. The decarboxylating enzyme used to release CO(2) around Rubisco particularly differs between C(4) species, a criterion used to distinguish three distinct biochemical C(4) subtypes. The phosphoenolpyruvate carboxykinase (PCK) serves as a primary decarboxylase in a minority of C(4) species. This enzyme is also present in C(3) plants, where it is responsible for nonphotosynthetic functions. The genetic changes responsible for the evolution of C(4)-specific PCK are still unidentified. Using phylogenetic analyses on PCK sequences isolated from C(3) and C(4) grasses, this study aimed at resolving the evolutionary history of C(4)-specific PCK enzymes. Four independent evolutions of C(4)-PCK were shown to be driven by positive selection, and nine C(4)-adaptive sites underwent parallel genetic changes in different C(4) lineages. C(4)-adaptive residues were also observed in C(4) species from the nicotinamide adenine dinucleotide phosphate-malic enzyme (NADP-ME) subtype and particularly in all taxa where a PCK shuttle was previously suggested to complement the NADP-ME pathway. Acquisitions of C(4)-specific PCKs were mapped on a species tree, which revealed that the PCK subtype probably appeared at the base of the Chloridoideae subfamily and was then recurrently lost and secondarily reacquired at least three times. Linking the genotype to subtype phenotype shed new lights on the evolutionary transitions between the different C(4) subtypes.

OBJECTIVE: To explore the potential of deep HIV-1 sequencing for adding clinically relevant information relative to viral population sequencing in heavily pre-treated HIV-1-infected subjects. METHODS: In a proof-of-concept study, deep sequencing was compared to population sequencing in HIV-1-infected individuals with previous triple-class virological failure who also developed virologic failure to deep salvage therapy including, at least, darunavir, tipranavir, etravirine or raltegravir. Viral susceptibility was inferred before salvage therapy initiation and at virological failure using deep and population sequencing genotypes interpreted with the HIVdb, Rega and ANRS algorithms. The threshold level for mutant detection with deep sequencing was 1%. RESULTS: 7 subjects with previous exposure to a median of 15 antiretrovirals during a median of 13 years were included. Deep salvage therapy included darunavir, tipranavir, etravirine or raltegravir in 4, 2, 2 and 5 subjects, respectively. Self-reported treatment adherence was adequate in 4 and partial in 2; one individual underwent treatment interruption during follow-up. Deep sequencing detected all mutations found by population sequencing and identified additional resistance mutations in all but one individual, predominantly after virological failure to deep salvage therapy. Additional genotypic information led to consistent decreases in predicted susceptibility to etravirine, efavirenz, nucleoside reverse transcriptase inhibitors and indinavir in 2, 1, 2 and 1 subject, respectively. Deep sequencing data did not consistently modify the susceptibility predictions achieved with population sequencing for darunavir, tipranavir or raltegravir. CONCLUSIONS: In this subset of heavily pre-treated individuals, deep sequencing improved the assessment of genotypic resistance to etravirine, but did not consistently provide additional information on darunavir, tipranavir or raltegravir susceptibility. These data may inform the design of future studies addressing the clinical value of minority drug-resistant variants in treatment-experienced subjects.

This article lies within the sphere of studies initiated recently in various social sciences and which aim to introduce women's problems as an element of analysis, or in other words, the gender perspective. In the field of geography, the earliest contributions of this nature were made in English-speaking countries. It is only in the 1980s that similar contributions begin to appear in Spanish geography, albeit sporadically . In the first part of this article, an analysis is made of the presence of women geographers in Spanish universities, based on a questionnaire submitted to twenty-six departments of geography. The questionnaires provide information on the age, sex and marital status of women staff, and other relevant facts. It becomes evident that women lecturers are in the minority in Spanish university Geography Departments, especially in the top posts, although the percentage compares favourably with English-speaking countries. The second part of the article consists of a study of the written contributions of women geographers through the analysis of the various geographical magazines published by geography departments and other related bodies. The author reaches the conclusion that the percentage of articles written by women geographers is even lower than the corresponding percentage of staff members. Especially noteworthy is the very limited number of articles in the fields of physical geography and geographical theory, in contrast to a certain tendency to publish studies on, for example, population or urban topics with a highly restricted territorial scope

BACKGROUND Previous studies have demonstrated the efficacy of treatment for latent tuberculosis infection (TLTBI) in persons infected with the human immunodeficiency virus, but few studies have investigated the operational aspects of implementing TLTBI in the co-infected population.The study objectives were to describe eligibility for TLTBI as well as treatment prescription, initiation and completion in an HIV-infected Spanish cohort and to investigate factors associated with treatment completion. METHODS Subjects were prospectively identified between 2000 and 2003 at ten HIV hospital-based clinics in Spain. Data were obtained from clinical records. Associations were measured using the odds ratio (OR) and its 95% confidence interval (95% CI). RESULTS A total of 1242 subjects were recruited and 846 (68.1%) were evaluated for TLTBI. Of these, 181 (21.4%) were eligible for TLTBI either because they were tuberculin skin test (TST) positive (121) or because their TST was negative/unknown but they were known contacts of a TB case or had impaired immunity (60). Of the patients eligible for TLTBI, 122 (67.4%) initiated TLTBI: 99 (81.1%) were treated with isoniazid for 6, 9 or 12 months; and 23 (18.9%) with short-course regimens including rifampin plus isoniazid and/or pyrazinamide. In total, 70 patients (57.4%) completed treatment, 39 (32.0%) defaulted, 7 (5.7%) interrupted treatment due to adverse effects, 2 developed TB, 2 died, and 2 moved away. Treatment completion was associated with having acquired HIV infection through heterosexual sex as compared to intravenous drug use (OR:4.6; 95% CI:1.4-14.7) and with having taken rifampin and pyrazinamide for 2 months as compared to isoniazid for 9 months (OR:8.3; 95% CI:2.7-24.9). CONCLUSIONS A minority of HIV-infected patients eligible for TLTBI actually starts and completes a course of treatment. Obstacles to successful implementation of this intervention need to be addressed.
