Rôle de l'exercice dans l'approche multidisciplinaire de la lombalgie chronique

RÉSUMÉ L'exercice est utilisé dans le traitement de la lombalgie depuis plus de cent ans. La recherche dans ce domaine a commencé au milieu du XXème siècle puis s'est développée exponentiellement jusqu'à nos jours. La première étude de cette thèse a eu pour but de passer en revue cette abondante littérature scientifique. Il en est ressorti que l'exercice est un moyen efficace de prévention primaire et secondaire de la lombalgie. En tant que modalité de traitement, l'exercice permet de diminuer l'incapacité et la douleur et d'améliorer la condition physique et le statut professionnel des patients lombalgiques subaigus et chroniques. Parmi les caractéristiques de l'exercice, la supervision est essentielle. Des investigations ultérieures sont nécessaires afin d'identifier des sous-groupes de patients répondant favorablement à d'autres caractéristiques de l'exercice. L'exercice est souvent utilisé dans l'optique de maintenir les résultats obtenus à la suite d'un traitement, bien que peu d'études s'y soient penchées. La deuxième partie de cette thèse a eu pour objectifs d'évaluer l'efficacité d'un programme d'exercice (PE) suivi par des patients lombalgiques chroniques ayant complété une restauration fonctionnelle multidisciplinaire (RFM), en comparaison avec le suivi classique (SC) consistant simplement à encourager les patients à adopter un quotidien aussi actif que possible par la suite. Les résultats ont montré que les améliorations obtenues au terme de RFM étaient maintenues par les deux groupes à un an de suivi. Bien qu'aucune différence n'ait été obtenue entre les deux groupes, seul le groupe PE améliorait significativement l'incapacité et l'endurance isométrique des muscles du tronc. Une analyse économique a ensuite été réalisée afin d'évaluer la rentabilité de PE. L'évaluation de la qualité de vie des patients au terme de RFM et à un an de suivi permettait d'estimer les années de vie ajustées par leur qualité (QALYs) gagnées par chaque groupe. Les coûts directs (visites chez le médecin, spécialiste, physio, autres) et indirects (jours d'absence au travail) étaient estimés avant RFM et à un an de suivi à l'aide d'un agenda. Aucune différence significative n'était obtenue entre les groupes. Une mince différence de QALYs en faveur de PE ne se traduisait néanmoins pas en bénéfices mesurables. La recherche future devrait s'attacher à identifier un ou des sous-groupe(s) de patients pour lesquels SC ne permet pas de maintenir à long terme les améliorations obtenues au terme de RFM, et pour lesquels l'efficacité thérapeutique et la rentabilité économique de PE pourraient être accrues. ABSTRACT Exercise is used to treat low back pain for over a hundred years. Research in this area began in the mid-twentieth century and then grew exponentially until nowadays. The first study of this thesis was aimed to review this abundant scientific literature. It showed that exercise is effective in the primary and secondary prevention of low back pain. As a modality of treatment, exercise can reduce disability and pain and improve physical fitness and professional status of patients with subacute and chronic low back pain. Among different exercise characteristics, supervision is essential. Further investigations are needed to identify subgroups of patients responding positively to other characteristics of exercise. Exercise is often used as a post-treatment modality in order to maintain results over time, although only a few studies addressed this issue directly. The purpose of the second part of this thesis was to evaluate the effectiveness of an exercise program (EP) for patients with chronic low back pain who completed a functional multidisciplinary rehabilitation (FMR), compared to the routine follow-up (RF) which simply consisted of encouraging patients to adopt an active daily life thereafter. The results showed that improvements obtained at the end of FMR were maintained by both groups at one year follow-up. Although no difference was obtained between both groups, only the EP group significantly improved disability and isometric endurance of trunk muscles. An economic analysis was then carried out to assess the cost-effectiveness of EP. Based on the evaluation of patients' quality of life after FMR and at one year follow-up, an estimation of adjusted life years for their quality (QALYs) gained by each group was done. Direct costs (physician, specialist, physiotherapist, other therapists visits) and indirect costs (days off work) were measured before FMR and at one year follow-up using a cost diary. No significant difference was obtained between both groups. A slight difference in QALYs in favour of EP did yet not translate into measurable benefits. Future research should focus on identifying subgroups of patients for which RF is insufficient to reach long-term improvements after FMR, and for which the therapeutic effectiveness and cost-effectiveness of EP could be increased.

Loss of single HLA class I allospecificities in melanoma cells due to selective genomic abbreviations.

Expression of human leucocyte antigen (HLA) Class I molecules is essential for the recognition of malignant melanoma (MM) cells by CD8(+) T lymphocytes. A complete or partial loss of HLA Class I molecules is a potent strategy for MM cells to escape from immunosurveillance. In 2 out of 55 melanoma cell cultures we identified a complete phenotypic loss of HLA allospecificities. Both patients have been treated unsuccessfully with HLA-A2 peptides. To identify the reasons underlying the loss of single HLA-A allospecificities, we searched for genomic alterations at the locus for HLA Class I alpha-chain on chromosome 6 in melanoma cell cultures established from 2 selected patients with MM in advanced stage. This deficiency was associated with alterations of HLA-A2 gene sequences as determined by polymerase chain reaction-sequence specific primers (PCR-SSP). Karyotyping revealed a chromosomal loss in Patient 1, whereas melanoma cell cultures established from Patient 2 displayed 2 copies of chromosome 6. Loss of heterozygosity (LOH) using markers located around position 6p21 was detected in both cases. By applying group-specific primer-mixes spanning the 5'-flanking region of the HLA-A2 gene locus the relevant region was amplified by PCR and subsequent sequencing allowed alignment with the known HLA Class I reference sequences. Functional assays using HLA-A2-restricted cytotoxic T-cell clones were performed in HLA-A2 deficient MM cultures and revealed a drastically reduced susceptibility to CTL lysis in HLA-A2 negative cells. We could document the occurrence of selective HLA-A2 deficiencies in cultured advanced-stage melanoma metastases and identify their molecular causes as genomic alterations within the HLA-A gene locus.

Executive Summary of Combating Malnutrition

A new BAPEN report, Combating Malnutrition: Recommendations for Action, is the culmination of work undertaken by a group of experts in malnutrition, led by BAPEN. Launched in Parliament on 10 February 2009, it sets out how the vast majority of those at risk of the condition are living in the community – and not in care homes and hospitals, where the focus of Government action has been to date. It also sets out how the disproportionate burden of malnutrition in deprived areas exacerbates health inequalities. The report puts forward 25 actions that the Government needs to lead in order to reduce both the cost of the condition to the taxpayer, and the number of those at risk.

Histopathological and ultrastructural aspects of mice lungs experimentally infected with dengue virus serotype 2

Histological and ultrastructural alterations in lung tissue of BALB/c mice infected with dengue virus serotype 2 (non-neuroadapted), by intraperitoneal and intravenous routes were analyzed. Lung tissues were processed following the standard techniques for photonic and electron transmission microscopies. Histopathological and ultrastructural studies showed interstitial pneumonia, characterized by the presence of mononuclear cells. In the mouse model, the dengue virus serotype 2 seems to led to a transient inflammatory process without extensive damage to the interalveolar septa, but caused focal alterations of the blood-exchange barrier. Endothelial cells of blood capillaries exhibited phyllopodia suggesting activation by presence of dengue virus. Morphometrical analysis of mast cells showed an expressive increase of the number of these cells in peribronchiolar spaces and adjacent areas to the interalveolar septa. Alveolar macrophages showed particles dengue virus-like inside rough endoplasmic reticulum and Golgi complex, suggesting viral replication. The tissue alterations observed in our experimental model were similar to the observed in human cases of dengue fever and dengue hemorrhagic fever. Our results show that BALB/c mice are permissive host for dengue virus serotype 2 replication and therefore provides an useful model to study of morphological aspects of dengue virus infection.

Ageing Prisoners' Disease Burden: Is Being Old a Better Predictor than Time Served in Prison?

Background: The number of older prisoners entering and ageing in prison has increased in the last few decades. Ageing prisoners pose unique challenges to the prison administration as they have differentiated social, custodial and healthcare needs than prisoners who are younger and relatively healthier. Objective: The goal of this study was to explore and compare the somatic disease burden of old and young prisoners, and to examine whether it can be explained by age group and/or time served in prison. Methods: Access to prisoner medical records was granted to extract disease and demographic information of older (>50 years) and younger (≤49 years) prisoners in different Swiss prisons. Predictor variables included the age group and the time spent in prison. The dependent variable was the total number of somatic diseases as reported in the medical records. Results were analysed using descriptive statistics and a negative binomial model. Results: Data of 380 male prisoners from 13 different prisons in Switzerland reveal that the mean ages of older and younger prisoners were 58.78 and 34.26 years, respectively. On average, older prisoners have lived in prison for 5.17 years and younger prisoners for 2.49 years. The average total number of somatic diseases reported by older prisoners was 2.26 times higher than that of prisoners below 50 years of age (95% CI 1.77-2.87, p < 0.001). Conclusion: This study is the first of its kind to capture national disease data of prisoners with a goal of comparing the disease burden of older and younger prisoners. Study findings indicate that older inmates suffer from more somatic diseases and that the number of diseases increases with age group. Results clearly illustrate the poorer health conditions of those who are older, their higher healthcare burden, and raises questions related to the provision of healthcare for inmates growing old in prison. © 2014 S.

Paternity and health services. Qualitative research on men's experiences during pregnancy, delivery and postpartum of theirs partners

Background: Little research has been carried out with regards to the inclusion of men during the birth process. The objective of this paper involves exploring the needs and expectations of the health services manifested by a group of fathers as a result of their experience during the birth process. Methods: Qualitative research was carried out in Granada in 2004 via individual interviews with fathers who showed shared responsibility in the upbringing. The profile is: employment, medium-high educational level, one or more child: 0-6 months of age. The transcript was subsequently submitted to hermeneutic analysis. Results: Some semantic constructs are: 1) Health Services do not concede the women as protagonists, 2) Birth process is depending on the body. Fathers can only support and fight for the relevance of men, 3) Men seem like “invisible”, 4) Health services inhibit their participation, and 5) have dealings with fathers according to their gender roles. The participants address the relationship between expectations of care during the birth process and unsatisfied demands, and the manner in which they employ the obstacles encountered within health services that inhibit their participation as arguments that confirm their separation from the process. Conclusions: This paper draws attention to the limited scope of the provision of healthcare during the birth process in terms of protagonism afforded to fathers. Indeed, despite their requisitory discourse, the interviewees manifest contradictory attitudes in the face of changes that require them to make commitments. We identify elements that could be improved to adapt services to the needs of fathers and vice versa.

Deficiencia nutricional de yodo en gestantes pertenecientes al distrito sanitario Sierra de Huelva-Andévalo, sur de España

Background. Iodine is an essential trace element implicated in synthesis of thyroid hormones. Iodine requirements vary throughout life. Yhis iodine requirement is increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected an iodine-deficient area in the province of Huelva, specially in dictrict Sierra de Huelva-Andévalo by means of neonatal TSH determinations. Objective. To reinforce the iodine supplementation campaign and its impact on their newborns in order to assess nutrition iodine status in 'pregnant women using questionnaire and ioduria determination. Material and methods. This study has been jointly carried out by Congenital Hypothiroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hosplital (Seville) and the Gynecology and Clinical Analysis Unit of the Río Tinto Hospital (Huelva) during two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determined by high-resolution liquid chromatography. Data from pregnant and results of the studied variables were analyzed with SPSS v.13.0. Conclusions. Pregnant women from the sanitary district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaire suggest that this iodine deficiency is consequence of an insufficient iodine intake and a low adherence to the treatment.

A genome-wide significant linkage for severe depression on chromosome 3: the depression network study.

Objective: The purpose of this study was to find loci for major depression via linkage analysis of a large sibling pair sample. Method: The authors conducted a genome-wide linkage analysis of 839 families consisting of 971 affected sibling pairs with severe recurrent major depression, comprising waves I and II of the Depression Network Study cohort. In addition to examining affected status, linkage analyses in the full data set were performed using diagnoses restricted by impairment severity, and association mapping of hits in a large case-control data set was attempted. Results: The authors identified genome-wide significant linkage to chromosome 3p25-26 when the diagnoses were restricted by severity, which was a maximum LOD score of 4.0 centered at the linkage marker D3S1515. The linkage signal identified was genome-wide significant after correction for the multiple phenotypes tested, although subsequent association mapping of the region in a genome-wide association study of a U.K. depression sample did not provide significant results. Conclusions: The authors report a genome-wide significant locus for depression that implicates genes that are highly plausible for involvement in the etiology of recurrent depression. Despite the fact that association mapping in the region was negative, the linkage finding was replicated by another group who found genome-wide-significant linkage for depression in the same region. This suggests that 3p25-26 is a new locus for severe recurrent depression. This represents the first report of a genome-wide significant locus for depression that also has an independent genome-wide significant replication.

Current epidemiological status of schistosomiasis in the state of Pernambuco, Brazil

Uncontrolled peripheral urbanisation coupled with environmental degradation has affected the status of schistosomiasis in Pernambuco (PE), Brazil. This endemic disease continues to perpetuate its transmission in rural areas and has also become a cause for concern in coastal towns of the state. The lack of basic infrastructure (sanitation and health programmes) to support the new urban areas leads to faecal contamination of natural aquatic environments, resulting in consequent infection of vector snails and the emergence of new sources of schistosomiasis transmission. In the present paper, we discuss the current epidemiological status of schistosomiasis in PE. We have consolidated and analysed information from parasitological, malacological and morbidity surveys undertaken by the group of researchers at the Laboratory of Schistosomiasis, Centro de Pesquisas Aggeu Magalhães-Fiocruz. The results of our analysis show: (i) the maintenance of the levels of schistosomiasis in the rural Zona da Mata, PE, (ii) the record of the human cases of schistosomiasis and the foci of infected snails detected along the coast of PE through 2007, (iii) the high record of the severe clinical form of schistosomiasis in the metropolitan region of Recife (RMR) and (iv) new breeding sites of schistosomiasis vector snails that were identified in a 2008 survey covering the RMR and the coastal localities of PE.
