Risk factors of latent tuberculosis infection among asylum-seekers recently arrived in Switzerland : A pilot study in Vaud county

Background: Asylum seekers may have a higher rate of latenttuberculosis infection (LTBI) than resident populations in Westerncountries. LTBI can be detected by an Interferon Gamma ReleaseAssay (IGRA). Screening asylum seekers at highest risk for LTBI orfuture tuberculosis by IGRA could be considered. The aims of this pilotstudy were to assess the prevalence and the risk factors of LTBI amonga group of asylum seekers recently arrived in Switzerland.Methods: A prospective cross-sectional study was performed amongadult asylum seekers, staying in two migrant centers of the Vaud county,Switzerland, after a first screening for active tuberculosis at the border.The participants were offered IGRA screening using T-SPOT.TB andwere questioned about risk factors associated with LTBI. Migrants with apositive test had a chest radiograph and a medical examination. Thosewith active tuberculosis were excluded and were treated. The migrantswith LTBI received a preventive treatment, if indicated. The risk factorswere analyzed by univariate and multivariate logistical regression.Results: Among 788 migrants recently arrived, 639 were adults, 393agreed to be screened (61.50%) and 98 of them had a positive T-SPOT.TB (24.93%) of which 5 (5.1%) had an active tuberculosis (previouslynot detected at the border), and 2 had already been treated for activetuberculosis. In univariate analysis, the major risk factors associatedwith LTBI were country of origin and travel conditions. Compared withmigrants from Balkanic countries, migrants from Africa had an OR forLTBI of 3.68, migrants from Asia an OR of 4.3 and migrants fromFormer Soviet Union an OR of 4.5. Migrants who crossed severalborders before arriving in Switzerland had an OR of LTBI of 2.49compared with migrants who came directly from the home country.Age, cough and prior exposure to tuberculosis had a non-significantinfluence on the rate of test positivity. In multivariate analysis, thecombination of country of origin, travel conditions, age, cough andexposure to tuberculosis resulted in a score with optimal predictivevalue (Roc = 81%).Conclusions: Asylum seekers recently arrived in Vaud county had ahigh prevalence of LTBI and active tuberculosis. The major risk factorswere country of origin and travel conditions. Selecting for screening byIGRA the asylum seekers with the highest risk factors seems possible.

Preparing for action : creating a plan 9. Taking action to change an addiction 10. The long haul : well-maintained recovery 11. Prevention : interfering with the process of becoming addicted 12. Designing interventions for recovery 13. Research on addiction and change. "The stages-of-change model has become widely known as a framework for conceptualizing recovery. Less well known are the processes that drive movement through the stages or how the stages apply to becoming addicted. From Carlo DiClemente, codeveloper of the Transtheoretical Model, this book offers a panoramic view of the entire continuum of addictive behavior change. Illuminated is the common path that individuals travel as they establish and reinforce new patterns of behavior, whether they are developing an addiction or struggling to free themselves from one, and regardless of the specific addictive behavior. Presenting cutting-edge research with significant clinical implications, the book addresses crucial questions of why, when, and how to intervene to bolster recovery in those already addicted and reach out effectively to people at risk. It is essential reading for clinicians, prevention specialists, and policymakers." [from Book Jacket]This resource was contributed by The National Documentation Centre on Drug Use.

Malaria prevention in travelers.

A common approach to malaria prevention is to follow the "A, B, C, D" rule: Awareness of risk, Bite avoidance, Compliance with chemoprophylaxis, and prompt Diagnosis in case of fever. The risk of acquiring malaria depends on the length and intensity of exposure; the risk of developing severe disease is primarily determined by the health status of the traveler. These parameters need to be assessed before recommending chemoprophylaxis and/or stand-by emergency treatment. This review discusses the different strategies and drug options available for the prevention of malaria during and post travel.

The leishmaniases - survival and expansion in a changing world: a mini-review

The number of cases of visceral and cutaneous leishmaniasis is increasing globally at an alarming rate irrespective of the region and the leishmaniases are amongst the top emergent diseases in spite of control measures. In the present review attention is drawn to some of the reasons for this. The leishmaniases have expanded beyond their natural ecotopes due to the ecological chaos caused by man and this in turn affects the levels of his exposure to the vectors. Examples of how different phenomana (such as war, civilian migration, immuno-suppression caused by medication and viral infections, globalization of work and leisure and transmission outside endemic areas) contribute to the spread and increase of the disease are discussed.

Personality and melanin-based colouration traits in barn owls, tawny owl and kestrels

Individuals need to adapt to their local environment in order to survive. When selection pressures differ in local populations, polymorphism can evolve. Colour polymorphism is one of the most obvious polymorphisms since it is readily observable. Different sources of colouration exist, but melanin-based colouration is one of the most common in birds. The melanocortin system produces this colouration and because the melanocortin system has pleiotropic effects on behavioural and physiological traits, it is a good candidate to be an underlying mechanism to explain the maintenance of colour polymorphism. In this thesis I studied three different raptors which all display melanin-based colouration; barn owls (Tyto alba), tawny owls (Strix aluco) and Eurasian kestrels (Falco tinnunculus). The main question was if there was a relationship between melanin-based colouration and individual behavioural differences. The underlying hypothesis is that colour could be a signal of certain adaptive traits. Our goal was to find evolutionary explanations for the persistence of colour polymorphism. I found that nestling kestrels and barn owls differ in anti-predatory behaviour, with respect to their melanic colouration (chapters 1 and 2). Darker individuals show less reaction to human handling, but in kestrels aggression and colouration are related in opposite ways than in barn owls. More reddish barn owls travel greater distances in natal dispersal and this behaviour is repeatable between parents and same sex offspring (chapter 3). Dark reddish tawny owls defend their nests more intensely against intruders and appear to suffer less from nest predation (chapter 4). Finally I show that polymorphism in the Melanocortin 1 receptor gene (MC1R), which is strongly correlated with reddish colouration in the barn owl, is related to natal dispersal distance, providing a first indication for a genetic basis of the relation between this behaviour and colouration (chapter 5). My results demonstrate a clear link between melanin-based colouration and animal personality traits. I demonstrated this relation in three different species, which shows there is most likely a general underlying mechanism responsible. Different predation pressures might have shaped the reactions to predation, but also differences in sex-related colouration. Male-like and female-like colouration might signal more or less aggressive behaviour. Fluctuating environmental conditions might cause different individual strategies to produce equal reproductive success. The melanocortin system with its pleiotropic effects might be an underlying mechanism, as suggested by the results from the genetic polymorphism, the similar results found in these three species and by the similar relations reported in other species. This thesis demonstrates that colouration and individual differences are correlated and it provides the first glimpse of an underlying system. We can now conduct a more directed search for underlying mechanisms and evolutionary explanations with the use of quantitative genetic methods.

Management of bleeding following major trauma: a European guideline

INTRODUCTION Evidence-based recommendations can be made with respect to many aspects of the acute management of the bleeding trauma patient, which when implemented may lead to improved patient outcomes. METHODS The multidisciplinary Task Force for Advanced Bleeding Care in Trauma was formed in 2005 with the aim of developing guidelines for the management of bleeding following severe injury. Recommendations were formulated using a nominal group process and the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) hierarchy of evidence and were based on a systematic review of published literature. RESULTS Key recommendations include the following: The time elapsed between injury and operation should be minimised for patients in need of urgent surgical bleeding control, and patients presenting with haemorrhagic shock and an identified source of bleeding should undergo immediate surgical bleeding control unless initial resuscitation measures are successful. A damage control surgical approach is essential in the severely injured patient. Pelvic ring disruptions should be closed and stabilised, followed by appropriate angiographic embolisation or surgical bleeding control, including packing. Patients presenting with haemorrhagic shock and an unidentified source of bleeding should undergo immediate further assessment as appropriate using focused sonography, computed tomography, serum lactate, and/or base deficit measurements. This guideline also reviews appropriate physiological targets and suggested use and dosing of blood products, pharmacological agents, and coagulation factor replacement in the bleeding trauma patient. CONCLUSION A multidisciplinary approach to the management of the bleeding trauma patient will help create circumstances in which optimal care can be provided. By their very nature, these guidelines reflect the current state-of-the-art and will need to be updated and revised as important new evidence becomes available.
