Interleukin-28B polymorphisms, IP-10, viral load and age predict the outcome of therapy in genotype 1 hepatitis C virus under real-life conditions

Background and Aims: IL28B polymorphisms, interferon (IFN)-gamma inducible protein-10 (IP-10) levels and the homeostasis model assessment of insulin resistance (HOMA-IR) score have been reported to predict rapid (RVR) and sustained (SVR) virological response in chronic hepatitis C (CHC), but it is not known whether these factors represent independent, clinically useful predictors. The aim of the study was to assess factors (including IL28B polymorphisms, IP-10 levels and HOMA-IR score) independently predicting response to therapy in CHC under real life conditions.Methods: Multivariate analysis of factors predicting RVR and SVR in 280 consecutive, treatment-naive CHC patients treated with pegylated IFN alpha and ribavirin in a prospective multicenter study.Results: Independent predictors of RVR were HCV RNA < 400,000 IU/ml (OR11.37; 95% CI 3.03-42.6), rs12980275 AA (vs. AG/GG) (OR 7.09; 1.97-25.56) and IP-10 (OR 0.04; 0.003-0.56) in HCV genotype 1 patients and lower baseline γ-glutamyl-transferase levels (OR = 0.02; 0.0009-0.31) in HCV genotype 3 patients. Independent predictors of SVR were rs12980275 AA (OR 9.68; 3.44-27.18), age < 40 yrs (OR = 4.79; 1.50-15.34) and HCV RNA < 400,000 IU/ml (OR 2.74; 1.03-7.27) in HCV genotype 1 patients and rs12980275 AA (OR = 6.26; 1.98-19.74) and age < 40 yrs (OR 5.37; 1.54-18.75) in the 88 HCV genotype 1 patients without a RVR. RVR was by itself predictive of SVR in HCV genotype 1 patients (32 of 33, 97%; OR 33.0; 4.06-268.32) and the only independent predictor of SVR in HCV genotype 2 (OR 9.0, 1.72-46.99; p=0.009) or 3 patients (OR 7.8, 1.43-42.67; p=0.01).Conclusions: In HCV genotype 1 patients, IL28B polymorphisms, HCV RNA load and IP-10 independently predict RVR. The combination of IL28B polymorphisms, HCV RNA level and age may yield more accurate pretreatment prediction of SVR. HOMA-IR score is not associated with viral response.

Assessment of Physical Activity and Energy Expenditure by GPS Combined With Accelerometry in Real-Life Conditions.

Background: Physical activity (PA) and related energy expenditure (EE) is often assessed by means of a single technique. Because of inherent limitations, single techniques may not allow for an accurate assessment both PA and related EE. The aim of this study was to develop a model to accurately assess common PA types and durations and thus EE in free-living conditions, combining data from global positioning system (GPS) and 2 accelerometers. Methods: Forty-one volunteers participated in the study. First, a model was developed and adjusted to measured EE with a first group of subjects (Protocol I, n = 12) who performed 6 structured and supervised PA. Then, the model was validated over 2 experimental phases with 2 groups (n = 12 and n = 17) performing scheduled (Protocol I) and spontaneous common activities in real-life condition (Protocol II). Predicted EE was compared with actual EE as measured by portable indirect calorimetry. Results: In protocol I, performed PA types could be recognized with little error. The duration of each PA type could be predicted with an accuracy below 1 minute. Measured and predicted EE were strongly associated (r = .97, P < .001). Conclusion: Combining GPS and 2 accelerometers allows for an accurate assessment of PA and EE in free-living situations.

Past and present: conditions of life during childhood and mortality of older adults

ABSTRACT OBJECTIVE: To analyze whether socioeconomic and health conditions during childhood are associated with mortality during old age. METHODS: Data were extracted from the SABE Study (Saúde, Bem-estar e Envelhecimento – Health, Welfare and Aging), which were performed in 2000 and 2006. The sample consisted of 2004 (1,355 living and 649 dead) older adults. The statistical analysis was performed based on Poisson regression models, taking into account the time variation of risk observed. Older adults’ demographic characteristics and life conditions were evaluated, as were the socioeconomic and lifestyle conditions they acquired during their adult life. RESULTS: Only the area of residence during childhood (rural or urban) remained as a factor associated with mortality at advanced ages. However, this association lost significance when the variables acquired during adulthood were added to the model. CONCLUSIONS: Despite the information regarding the conditions during childhood being limited and perhaps not accurately measure the socioeconomic status and health in the first years of life, the findings of this study suggest that improving the environmental conditions of children and creating opportunities during early adulthood may contribute to greater survival rates for those of more advanced years.

Barcoding human physical activity to assess chronic pain conditions.

BACKGROUND: Modern theories define chronic pain as a multidimensional experience - the result of complex interplay between physiological and psychological factors with significant impact on patients' physical, emotional and social functioning. The development of reliable assessment tools capable of capturing the multidimensional impact of chronic pain has challenged the medical community for decades. A number of validated tools are currently used in clinical practice however they all rely on self-reporting and are therefore inherently subjective. In this study we show that a comprehensive analysis of physical activity (PA) under real life conditions may capture behavioral aspects that may reflect physical and emotional functioning.¦METHODOLOGY: PA was monitored during five consecutive days in 60 chronic pain patients and 15 pain-free healthy subjects. To analyze the various aspects of pain-related activity behaviors we defined the concept of PA 'barcoding'. The main idea was to combine different features of PA (type, intensity, duration) to define various PA states. The temporal sequence of different states was visualized as a 'barcode' which indicated that significant information about daily activity can be contained in the amount and variety of PA states, and in the temporal structure of sequence. This information was quantified using complementary measures such as structural complexity metrics (information and sample entropy, Lempel-Ziv complexity), time spent in PA states, and two composite scores, which integrate all measures. The reliability of these measures to characterize chronic pain conditions was assessed by comparing groups of subjects with clinically different pain intensity.¦CONCLUSION: The defined measures of PA showed good discriminative features. The results suggest that significant information about pain-related functional limitations is captured by the structural complexity of PA barcodes, which decreases when the intensity of pain increases. We conclude that a comprehensive analysis of daily-life PA can provide an objective appraisal of the intensity of pain.

Fitness to drive and cannabis: Experimental and real-life case study validation of two blood THCCOOH thresholds to distinguish occasional users from heavy smokers

Introduction: THC-COOH has been proposed as a criterion to help to distinguish between occasional from regular cannabis users. However, to date this indicator has not been adequately assessed under experimental and real-life conditions. Methods: We carried out a controlled administration study of smoked cannabis with a placebo. Twenty-three heavy smokers and 25 occasional smokers, between 18 and 30 years of age, participated in this study [Battistella G et al., PloS one. 2013;8(1):e52545]. We collected data from a second real case study performed with 146 traffic offenders' cases in which the whole blood cannabinoid concentrations and the frequency of cannabis use were known. Cannabinoid levels were determined in whole blood using tandem mass spectrometry methods. Results: Significantly high differences in THC-COOH concentrations were found between the two groups when measured during the screening visit, prior to the smoking session, and throughout the day of the experiment. Receiver operating characteristic (ROC) curves were determined and two threshold criteria were proposed in order to distinguish between these groups: a free THC-COOH concentration below 3 μg/L suggested an occasional consumption (≤ 1 joint/week) while a concentration higher than 40 μg/L corresponded to a heavy use (≥ 10 joints/month). These thresholds were successfully tested with the second real case study. The two thresholds were not challenged by the presence of ethanol (40% of cases) and of other therapeutic and illegal drugs (24%). These thresholds were also found to be consistent with previously published experimental data. Conclusion: We propose the following procedure that can be very useful in the Swiss context but also in other countries with similar traffic policies: If the whole blood THC-COOH concentration is higher than 40 μg/L, traffic offenders must be directed first and foremost toward medical assessment of their fitness to drive. This evaluation is not recommended if the THC-COOH concentration is lower than 3 μg/L. A THC-COOH level between these two thresholds can't be reliably interpreted. In such a case, further medical assessment and follow up of the fitness to drive are also suggested, but with lower priority.

Indicadores sociales y psicosociales de calidad de vida de las personas mayores en un municipio = Social and psychosocial quality of life indicators of older persons in a municipality

A research about the quality of life of the older persons of a municipality starting from the analysis of the perceptions, evaluations and expectations related to concrete spheres of their lives (familiar characteristics, housing, health, nearby environment, activities, needs and dependencies and persons helping them to satisfy needs) is presented. Answers to 1988 questionnaires obtained from two representative samples of older per - sons living in private homes in the city have been analysed: persons over 65 years old and a specific one composed by a sub-sample of the general one, with persons over 75 years living alone. Data shaping contextual indicators related to housing have been analysed. The auto - nomy to drive and the evaluation of on’s health seem to be positive indicators to take in account while sutying quality of life at these ages. Sentinel indicators of the physical and relational conditions in the family and indicators of dependency are analysed as well. The evaluations of the older persons about their own life conditions are also analysed through psychosocial indicators connected to housing, nearby environmenent, their activities andincomes. The results obtained are applicable in order to improve the decision making process in social intervention programmes developed in the field of ageing aiming to take into account their perspectives

Les conditions de vie dans l'enfance en milieu urbain et la longévité : le cas de la ville de Québec en 1901

Le présent mémoire s’inscrit dans un projet, financé par le CRSH, visant l’étude des conditions de vie dans l’enfance et la survie aux grands âges L’augmentation de la longévité et de la mortalité observée dans les pays industrialisés depuis plus d’un siècle ont mené à l’émergence d’un courant de recherche visant à identifier les causes de ces progrès. Il a été soulevé que les conditions de vie dans l’enfance pourraient y jouer un rôle. L’objectif de ce mémoire est donc de mettre en lumière les déterminants qui sont en cause en étudiant la mortalité au-delà de 40 ans d’une population urbaine canadienne-française en phase d’industrialisation, soit, celle de la ville de Québec au début du 20ème siècle. Plus spécifiquement, une analyse descriptive de la population étudiée sera effectuée et suivra une analyse statistique à l’aide de modèles de risques proportionnels de Cox qui prendront en compte différentes facettes des conditions de vie. Au coeur de ce mémoire a été l’élaboration d’une base de données se basant sur le Canadian Families Project et créée à partir du recensement canadien de 1901. Cette dernière nous a permis de dresser un portrait des conditions de vie dans l’enfance, telles qu’elles étaient au tournant du 20ème siècle, de la population étudiée. Nous avons complété cette base de données en recueillant des informations sur les mariages à l’aide des fichiers de du projet BALSAC ainsi que les âges au décès des individus de l’échantillon en consultant les fiches de l’État civil. Nous avons pu mettre en lumière que les individus ayant passé leur enfance dans un ménage de type complexe affichent une mortalité moins élevée (de près de 35%) que pour les structures familiales simples. De plus, les individus qui ont grandi dans un ménage dont le chef était bilingue ou occupait un emploi qualifié ont des risques de mortalité inférieurs de près du tiers par rapport aux autres. Nous avons aussi trouvé que les résidents de la Basse-Ville courraient un risque de mortalité jusqu’à 50% plus élevé que celui de ceux provenant d’autres districts de la ville.

Ambiente de desenvolvimento e início da vida reprodutiva em mulheres Brasileiras

Modelos teóricos inspirados na teoria da história de vida têm avaliado padrões de reprodução humanos em países desenvolvidos, com resultados ainda não conclusivos. Em vista das condições de vida na população brasileira, foram investigadas relações entre marcos da carreira reprodutiva feminina, condições ambientais e variáveis psicossociais relacionadas às condições de criação. Foram entrevistadas 606 mulheres em seis estados. Os resultados apóiam a teoria da história de vida, mostrando associações entre condições de vida na infância e início da vida sexual e da reprodução, mas não com a idade da menarca. Sugerimos que diferentes marcadores da vida reprodutiva podem estar sob controle de diferentes fenômenos e que a diversidade de condições da população brasileira oferece contextos alternativos para testar hipóteses.

Banana fiber craftwork in the perspective of multifunctionality in quilombola communities

This study pursued an analysis of a modality of craftwork activity developed as an alternative for occupation and income using banana crop wastes. It is the banana fiber craftwork. The experience was developed in quilombola communities in the region of Vale do Ribeira, S (a) over tildeo Paulo State, Brazil. The correlation between the craftwork and other activities used as a source of income, like organic banana and other land crops, and rural tourism, was established. Using multifunctionality as a reference, it was intended to focus on the craftwork. activity within the dynamics of rural families in their territories, considering the economic, social, cultural and environmental issues involved in the quilombola`s activities. This permitted the evaluation of their contributions to the maintainance of the life conditions of these communities.

Futebol: o caminho de África até à Europa

Similarly to its past, Africa plays a similar role in the football world as it did during History, if we look at the creation of some of the most powerful empires in the world (the Portuguese, French or English, for example) – as an almost unlimited workforce ‘supplier’. Africa is still searching for its own place in the football world map. With a recent history filled with social conflicts, civil wars and racial discrimination, it was possibly in this continent that the sport was first seen as a means towards social evolution and as ‘peacemaker’. Although these problems also exist in African stadiums, supporters all over the continent go to matches to celebrate and socialize; in a reality constantly shrouded in conflicts and oppression, football is like a ‘light at the end of the tunnel’ to those who believe in a continent sustained by healthy political relations between countries, democratic values and a socially fair ‘use’ of a country’s potential – and always for the profit of its own people. But while see the attempt to use football with that objective, others see it as their ticket out of their country, to avoid getting involved in military conflicts and seek better life conditions for themselves and their families (both those who accompany them and those who remain in Africa). Others, still, try to make the most of others’ will to leave a less favourable social reality; Portugal, for its past as a colonizing country, also saw in the African players a way to develop the football phenomenon in its European territory. This article attempts to analyze the influence of Portuguese colonialism in the emigration of African players to Europe, since Portugal presents itself as one of the biggest ‘importers’ of these players.

Dimensions of self-rated health in older adults

OBJECTIVE To analyze the association between negative self-rated health and indicators of health, wellbeing and sociodemographic variables in older adults. METHODS Cross-sectional study that used data from a population-based health survey with a probability cluster sample that was carried out in Campinas, SP, Southeastern Brazil,, in 2008 and 2009. The participants were older adults (≥ 60 years) and the dependent variable was self-rated health, categorized as: excellent, very good, good, bad and very bad. The adjusted prevalence ratios were estimated by means of Poisson multiple regression. RESULTS The highest prevalences of bad/very bad self-rated health were observed in the individuals who never attended school, in those with lower level of schooling, with monthly per capita family income lower than one minimum salary. Individuals who scored five or more in the physical health indicator also had bad self-rated health, as well as those who scored five or more in the Self-Reporting Questionnaire 20 and those who did not refer feeling happiness all the time. CONCLUSIONS The independent effects of material life conditions, physical and mental health and subjective wellbeing, observed in self-rated health, suggest that older adults can benefit by health policies supported by a global and integrative view of old age.
