Development and evaluation of an Individualised Outcome Measure (IOM) for randomised controlled trials in mental health

Predefined, researcher-selected outcomes are routinely used as the clinical end-point in randomised controlled trials (RCTs); however, individualised approaches may be an effective way to assess outcome in mental health research. The present study describes the development and evaluation of the Individualised Outcome Measure (IOM), which is a patient-specific outcome measure to be used for RCTs of complex interventions. IOM was developed using a narrative review, expert consultation and piloting with mental health service users (n=20). The final version of IOM comprises two components: Goal Attainment (GA) and Personalised Primary Outcome (PPO). For GA, patients identify one relevant goal at baseline and rate its attainment at follow-up. For PPO, patients choose an outcome domain related to their goal from a predefined list at baseline, and complete a standardised questionnaire assessing the chosen outcome domain at baseline and follow-up. A feasibility study indicated that IOM had adequate completion (89%) and acceptability (96%) rates in a clinical sample (n=84). IOM was then evaluated in an RCT (ISRCTN02507940). GA and PPO components were associated with each other and with the trial primary outcome. The use of the PPO component of IOM as the primary outcome could be considered in future RCTs

Effects of clinical decision topic on patients’ involvement in and satisfaction with decisions and their subsequent implementation

Clinical decision-making is the vehicle for mental health care delivery, and predictors of decision-making experience and adherence are under-researched. The aim was to investigate the relationship between decision topic and kind of involvement in the decision, satisfaction and subsequent implementation, from both staff and patient perspectives

Serological evidence of influenza a viruses in frugivorous bats from Africa

Bats are likely natural hosts for a range of zoonotic viruses such as Marburg, Ebola, Rabies, as well as for various Corona- and Paramyxoviruses. In 2009/10, researchers discovered RNA of two novel influenza virus subtypes - H17N10 and H18N11 - in Central and South American fruit bats. The identification of bats as possible additional reservoir for influenza A viruses raises questions about the role of this mammalian taxon in influenza A virus ecology and possible public health relevance. As molecular testing can be limited by a short time window in which the virus is present, serological testing provides information about past infections and virus spread in populations after the virus has been cleared. This study aimed at screening available sera from 100 free-ranging, frugivorous bats (Eidolon helvum) sampled in 2009/10 in Ghana, for the presence of antibodies against the complete panel of influenza A haemagglutinin (HA) types ranging from H1 to H18 by means of a protein microarray platform. This technique enables simultaneous serological testing against multiple recombinant HA-types in 5μl of serum. Preliminary results indicate serological evidence against avian influenza subtype H9 in about 30% of the animals screened, with low-level cross-reactivity to phylogenetically closely related subtypes H8 and H12. To our knowledge, this is the first report of serological evidence of influenza A viruses other than H17 and H18 in bats. As avian influenza subtype H9 is associated with human infections, the implications of our findings from

Rationale, component description and pilot evaluation of a physical health promotion measure for people with mental disorders across Europe

Introduction: The HELPS project aimed at developing a toolkit for the promotion of physical health in people with mental disorders to reduce the substantial excess morbidity and mortality in the target group. Methods: The HELPS toolkit was developed by means of national and international literature reviews, Delphi rounds with mental health experts and focus groups with mental health experts and patients/ residents in 14 European countries. The toolkit was translated into the languages of all participating countries, and usability of toolkit modules was tested. Results: The toolkit consists of several modules addressing diverse somatic health problems, lifestyle, environment issues, patient goals and motivation for health-promotion measures. It aims at empowering people with mental illness and staff to identify physical health risks in their specific contexts and to select the most appropriate modules from a range of health promotion tools. Discussion: The HELPS project used an integrative approach to the development of simple tools for the target population and is available online in 14 European languages. Preliminary evidence suggests that the toolkit can be used in routine care settings and should be put to test in controlled trials to reveal its potential impact

Influenza at the animal-human interface: A review of the literature for virological evidence of human infection with swine or avian influenza viruses other than A(H5N1)

Factors that trigger human infection with animal influenza virus progressing into a pandemic are poorly understood. Within a project developing an evidence-based risk assessment framework for influenza viruses in animals, we conducted a review of the literature for evidence of human infection with animal influenza viruses by diagnostic methods used. The review covering Medline, Embase, SciSearch and CabAbstracts yielded 6,955 articles, of which we retained 89; for influenza A(H5N1) and A(H7N9), the official case counts of the World Health Organization were used. An additional 30 studies were included by scanning the reference lists. Here, we present the findings for confirmed infections with virological evidence. We found reports of 1,419 naturally infected human cases, of which 648 were associated with avian influenza virus (AIV) A(H5N1), 375 with other AIV subtypes, and 396 with swine influenza virus (SIV). Human cases naturally infected with AIV spanned haemagglutinin subtypes H5, H6, H7, H9 and H10. SIV cases were associated with endemic SIV of H1 and H3 subtype d

Getting More Out of Less - A Quantitative Serological Screening Tool for Simultaneous Detection of Multiple Influenza A Hemagglutinin-Types in Chickens

Current avian influenza surveillance in poultry primarily targets subtypes of interest for the veterinary sector (H5, H7). However, as virological and serological evidence suggest, surveillance of additional subtypes is important for public health as well as for the poultry industry. Therefore, we developed a protein microarray enabling simultaneous identification of antibodies directed against different HA-types of influenza A viruses in chickens. The assay successfully discriminated negative from experimentally and naturally infected, seropositive chickens. Sensitivity and specificity depended on the cut-off level used but ranged from 84.4% to 100% and 100%, respectively, for a cut off level of =1:40, showing minimal cross reactivity. As this testing platform is also validated for the use in humans, it constitutes a surveillance tool that can be applied in human-animal interface studies

Weighing serological evidence of human exposure to animal influenza viruses − A literature review

Assessing influenza A virus strains circulating in animals and their potential to cross the species barrier and cause human infections is important to improve human influenza surveillance and preparedness. We reviewed studies describing serological evidence of human exposure to animal influenza viruses. Comparing serological data is difficult due to a lack of standardisation in study designs and in laboratory methods used in published reports. Therefore, we designed a scoring system to assess and weigh specificity of obtained serology results in the selected articles. Many studies report reliable evidence of antibodies to swine influenza viruses among persons occupationally exposed to pigs. Most avian influenza studies target H5, H7 and H9 subtypes and most serological evidence of human exposure to avian influenza viruses is reported for these subtypes. Avian influenza studies receiving a low grade in this review often reported higher seroprevalences in humans compared with studies with a high grade. Official surveillance systems mainly focus on avian H5 and H7 viruses. Swine influenza viruses and avian subtypes other than H5 and H7 (emphasising H9) should be additionally included in official surveillance systems. Surveillance efforts should also be directed towards understudied geographical areas, such as Africa and South America

HOCHRECHNUNGEN ÜBER DIE ZUKÜNFTIGE ZAHL DEMENZKRANKER: ZU WENIG BERÜCKSICHTIGUNG WEITER STEIGENDER LEBENSERWARTUNG?

Background: Several authors pointed out that in the next decades dementia will affect a considerably increasing number of the elderly. The question was raised if lifeexpectancy was projected to conservative, resulting in revisions with higher life-expectancy and larger numbers of the oldest population. The present paper analyses the influence of such revisions on the future numbers of dementia sufferers in Austria. Subjects and methods: For this purpose we used metaanalyses of epidemiological studies and the population projections for the period until 2050 of the Austrian Bureau of Statistics as well as of the United Nations Population Division of the year 2001 as well of the year 2005. Results: Using the extrapolations of the Austrian Bureau of Statistics of the year 1999 as well as of the United Nations Population Division of the year 2001, the number of dementia cases in Austria in the year 2050 will rise to about 233 thousands. According to the four years later performed extrapolations of the United Nations Population Division of the year 2005, dementia cases in Austria will raise to about 262 thousands in the year 2050. Conclusions: In the next decades, the number of persons suffering from dementia will rise considerably. Increasing lifeexpectancy will result in markedly higher numbers of persons with dementia than estimated from earlier population projections. Nevertheless, this is the first analysis of future dementia cases based on projections from two different dates, but using the same source. We must conclude that the dramatically increasing number of dementia cases requires comprehensive planning of the health and social care system.Hintergrund: Verschiedene Autoren haben berichtet, dass aufgrund der zunehmend älter werdenden Bevölkerung mit einer Zunahme von Demenzerkrankungen zu rechnen ist. Es gibt Hinweise darauf, dass Bevölkerungsprognosen die Lebenserwartung als zu gering einschätzen und später nach oben korrigiert werden müssen. Die vorliegende Arbeit untersucht die Frage, in welchem Umfang sich solche Änderungen auf die zukünftigen Zahlen von Demenzkranken auswirken. Methodik: Zu diesem Zweck wurden Meta-Analysen epidemiologischer Studien und die Bevölkerungsprognosen des Österreichischen Statistischen Zentralamtes sowie der Vereinten Nationen für Österreich verwendet. Ergebnisse: Die Bevölkerungsprognosen des Statistischen Zentralamtes des Jahres 1999 sowie der Vereinten Nationen 2001 ergeben einen hochgerechneten Anstieg von etwa 233.000 Demenzkranken in Österreich im Jahr 2050. Die nur vier Jahre später durchgeführten Bevölkerungsprognosen der Vereinten Nationen 2005 führen aber zu einem Anstieg auf 262.000 Demenzkranke im Jahr 2050. Schlussfolgerungen: Es zeigt sich, dass Demenzerkrankungen deutlich zunehmen werden. Die gesteigerte künftige Lebenserwartung führt allerdings zu noch höheren Zahlen von Demenzkranken als früher errechnet. Allerdings ist dies die erste Hochrechnung über künftige Demenzkrankenbestände, die Bevölkerungsprognosen aus derselben Quelle, aber von unterschiedlichen Zeitpunkten verwendet. Dies erfordert umfangreiche Planungen der medizinischen und sozialen Versorgung

Exploring novel sero-epidemiological tools—Effect of different storage conditions on longitudinal stability of microarray slides comprising influenza A-, measles- and Streptococcus pneumoniae antigens

In this study we evaluated the long-term stability of a microarray-based serological screening platform, containing antigens of influenza A, measles and Streptococcus pneumoniae, as part of a preparedness research program aiming to develop assays for syndromic disease detection. Spotted microarray slides were kept at four different storage regimes with varying temperature and humidity conditions. We showed that under the standard storage condition in a temperature-controlled (21 °C) and desiccated environment (0% relative humidity), microarray slides remained stable for at least 22 months without loss of antigen quality, whereas the other three conditions (37 °C, desiccated; Room temperature, non-desiccated; Frozen, desiccated) produced acceptable results for some antigens (influenza A, S.pneumoniae), but not for others (measles). We conclude that these arrays for multiplex antibody testing can be prepared and stored for prolonged periods of time, which aids laboratory-preparedness and facilitates sero-epidemiological studies
