Predictors of favourable outcome in first-episode patients who refuse medication: results from the FEPOS study

There are suggestions that some first-episode psychosis (FEP) patients can have favourable outcome without antipsychotic medication. However, there is very limited data regarding patients' characteristics on which the decision to propose medication free treatment could be based. FEPOS is a fi le-based study of an epidemiological sample of 704 FEP patients treated at EPPIC, Melbourne, between 1998 and 2000. Among the 661 patients where data was available, 108 consistently refused medication during the entire duration of their treatment at EPPIC. In this paper we compared, within this sub-group, patients who had a favourable outcome with those who did not. Patients were aged between 15 and 29 years (M = 21.9, SD = 3.40) and the majority were male (70.4%, n = 76). Symptomatic remission data was available on 105 patients; of these patients 41.0% (n = 41) had achieved remission. Functional remission data was available on 100 patients; of these patients 33.0% (n = 33) had achieved functional remission. Combined remission was evident in 23.0% (n = 23) of patients. Three factors were associated with symptomatic remission: better premorbid functioning (based on GAF, OR = 1.07, p = 0.006), higher number of years of education (OR = 1.43, p = 0.020), and being employed or studying at service entry (OR = 2.59, p = 0.034). Three factors were associated with functional remission: shorter duration of prodrome (OR = 0.50, p = 0.043), severity of psychopathology (CGI-S, OR = 0.51, p = 0.024), and vocational status at service entry (OR = 4.29, p = 0.003). While various aspects of pre-morbid functioning seem to correlate with the possibility of a favourable outcome in FEP patients who refuse medication, various limitations need to be taken into account in this study.

Bond strength tests of dental adhesive systems and their correlation with clinical results : a meta-analysis

OBJECTIVE: To evaluate the variability of bond strength test results of adhesive systems (AS) and to correlate the results with clinical parameters of clinical studies investigating cervical restorations. MATERIALS AND METHODS: Regarding the clinical studies, the internal database which had previously been used for a meta-analysis on cervical restorations was updated with clinical studies published between 2008 and 2012 by searching the PubMed and SCOPUS databases. PubMed and the International Association for Dental Research abstracts online were searched for laboratory studies on microtensile, macrotensile and macroshear bond strength tests. The inclusion criteria were (1) dentin, (2) testing of at least four adhesive systems, (3) same diameter of composite and (4) 24h of water storage prior to testing. The clinical outcome variables were retention loss, marginal discoloration, detectable margins, and a clinical index comprising the three parameters by weighing them. Linear mixed models which included a random study effect were calculated for both, the laboratory and the clinical studies. The variability was assessed by calculating a ratio of variances, dividing the variance among the estimated bonding effects obtained in the linear mixed models by the sum of all variance components estimated in these models. RESULTS: Thirty-two laboratory studies fulfilled the inclusion criteria comprising 183 experiments. Of those, 86 used the microtensile test evaluating 22 adhesive systems (AS). Twenty-seven used the macrotensile test with 17 AS, and 70 used the macroshear test with 24 AS. For 28 AS the results from clinical studies were available. Microtensile and macrotensile (Spearman rho=0.66, p=0.007) were moderately correlated and also microtensile and macroshear (Spearman rho=0.51, p=0.03) but not macroshear and macrotensile (Spearman rho=0.34, p=0.22). The effect of the adhesive system was significant for microtensile and macroshear (p<0.001) but not for macrotensile. The effect of the adhesive system could explain 36% of the variability of the microtensile test, 27% of the macrotensile and 33% of the macroshear test. For the clinical trials, about 49% of the variability of retained restorations could be explained by the adhesive system. With respect to the correlation between bond strength tests and clinical parameters, only a moderate correlation between micro- and macrotensile test results and marginal discoloration was demonstrated. However, no correlation between these tests and a retention loss or marginal integrity was shown. The correlation improved when more studies were included compared to assessing only one study. SIGNIFICANCE: The high variability of bond strength test results highlights the need to establish individual acceptance levels for a given test institute. The weak correlation of bond-strength test results with clinical parameters leads to the conclusion that one should not rely solely on bond strength tests to predict the clinical performance of an adhesive system but one should conduct other laboratory tests like tests on the marginal adaptation of fillings in extracted teeth and the retention loss of restorations in non-retentive cavities after artificial aging.

Biblio-MetReS: A bibliometric network reconstruction application and server

Background: Reconstruction of genes and/or protein networks from automated analysis of the literature is one of the current targets of text mining in biomedical research. Some user-friendly tools already perform this analysis on precompiled databases of abstracts of scientific papers. Other tools allow expert users to elaborate and analyze the full content of a corpus of scientific documents. However, to our knowledge, no user friendly tool that simultaneously analyzes the latest set of scientific documents available on line and reconstructs the set of genes referenced in those documents is available. Results: This article presents such a tool, Biblio-MetReS, and compares its functioning and results to those of other user-friendly applications (iHOP, STRING) that are widely used. Under similar conditions, Biblio-MetReS creates networks that are comparable to those of other user friendly tools. Furthermore, analysis of full text documents provides more complete reconstructions than those that result from using only the abstract of the document. Conclusions: Literature-based automated network reconstruction is still far from providing complete reconstructions of molecular networks. However, its value as an auxiliary tool is high and it will increase as standards for reporting biological entities and relationships become more widely accepted and enforced. Biblio- MetReS is an application that can be downloaded from http://metres.udl.cat/. It provides an easy to use environment for researchers to reconstruct their networks of interest from an always up to date set of scientific documents.

Update on osteoporosis from the 2014 Santa Fe Bone symposium.

The 2014 Santa Fe Bone Symposium provided a setting for the presentation and discussion of the clinical relevance of recent advances in the fields of osteoporosis and metabolic bone disease. The format included oral presentations of abstracts by endocrinology fellows, plenary lectures, panel discussions and breakout sessions, with ample opportunities for informal discussions before and after scheduled events. Topics addressed in these proceedings included a review of the important scientific publications in the past year, fracture prevention in patients with dysmobility and immobility, fracture liaison services for secondary fracture prevention, management of pre-menopausal osteoporosis, the role of bone microarchitecture in determining bone strength, measurement of microarchitecture in clinical practice and methods to improve the quality of bone density testing. This is a report of the proceedings of the 2014 Santa Fe Bone Symposium.

Cancer incidence in Neuchâtel (2003-2007)

REGISTRATION AREA: The Neuchâtel Cancer Registry covers the Frenchspeaking canton of Neuchâtel in western Switzerland, which shares a border with France. The canton is mainly rural, with only two cities (of approximately 35 000 residents each). Almost all residents are Caucasian; 38% are Protestant and 31% are Catholic. Foreign residents (predominantly of Mediterranean origin) account for about 23% of the population. The main occupational sectors in the canton are watch-making and the microtechnical industry (35%), agriculture (4%), and services (61%). REGISTRY STRUCTURE AND METHODS: The bulk of information is provided by the Neuchâtel Institute of Pathology (INAP) through submission of biopsy, cytology, and autopsy reports. Notiĺcation is voluntary for medical institutions. Additional information is abstracted by the registry staff from computerized hospital charts. The registry routinely integrates abstracts of medical records into its database, and performs periodic electronic linkage between the registry database and the centralized cantonal administrative population database (for the purpose of active follow-up). All death certiĺcates are checked annually against the registry ĺles.

Automatic target validation based on neuroscientific literature mining for tractography.

Target identification for tractography studies requires solid anatomical knowledge validated by an extensive literature review across species for each seed structure to be studied. Manual literature review to identify targets for a given seed region is tedious and potentially subjective. Therefore, complementary approaches would be useful. We propose to use text-mining models to automatically suggest potential targets from the neuroscientific literature, full-text articles and abstracts, so that they can be used for anatomical connection studies and more specifically for tractography. We applied text-mining models to three structures: two well-studied structures, since validated deep brain stimulation targets, the internal globus pallidus and the subthalamic nucleus and, the nucleus accumbens, an exploratory target for treating psychiatric disorders. We performed a systematic review of the literature to document the projections of the three selected structures and compared it with the targets proposed by text-mining models, both in rat and primate (including human). We ran probabilistic tractography on the nucleus accumbens and compared the output with the results of the text-mining models and literature review. Overall, text-mining the literature could find three times as many targets as two man-weeks of curation could. The overall efficiency of the text-mining against literature review in our study was 98% recall (at 36% precision), meaning that over all the targets for the three selected seeds, only one target has been missed by text-mining. We demonstrate that connectivity for a structure of interest can be extracted from a very large amount of publications and abstracts. We believe this tool will be useful in helping the neuroscience community to facilitate connectivity studies of particular brain regions. The text mining tools used for the study are part of the HBP Neuroinformatics Platform, publicly available at http://connectivity-brainer.rhcloud.com/.

Positive Outcomes Influence the Rate and Time to Publication, but Not the Impact Factor of Publications of Clinical Trial Results

Objectives: Publication bias may affect the validity of evidence based medical decisions. The aim of this study is to assess whether research outcomes affect the dissemination of clinical trial findings, in terms of rate, time to publication, and impact factor of journal publications. Methods and Findings: All drug-evaluating clinical trials submitted to and approved by a general hospital ethics committee between 1997 and 2004 were prospectively followed to analyze their fate and publication. Published articles were identified by searching Pubmed and other electronic databases. Clinical study final reports submitted to the ethics committee, final reports synopses available online and meeting abstracts were also considered as sources of study results. Study outcomes were classified as positive (when statistical significance favoring experimental drug was achieved), negative (when no statistical significance was achieved or it favored control drug) and descriptive (for non-controlled studies). Time to publication was defined as time from study closure to publication. A survival analysis was performed using a Cox regression model to analyze time to publication. Journal impact factors of identified publications were recorded. Publication rate was 48·4% (380/785). Study results were identified for 68·9% of all completed clinical trials (541/785). Publication rate was 84·9% (180/212) for studies with results classified as positive and 68·9% (128/186) for studies with results classified as negative (p<0·001). Median time to publication was 2·09 years (IC95 1·61-2·56) for studies with results classified as positive and 3·21 years (IC95 2·69-3·70) for studies with results classified as negative (hazard ratio 1·99 (IC95 1·55-2·55). No differences were found in publication impact factor between positive (median 6·308, interquartile range: 3·141-28·409) and negative result studies (median 8·266, interquartile range: 4·135-17·157). Conclusions: Clinical trials with positive outcomes have significantly higher rates and shorter times to publication than those with negative results. However, no differences have been found in terms of impact factor.

Vulnerability as a heuristic for interdisciplinary research: Assessing the thematic and methodological structure of empirical life-course studies

Changes in human lives are studied in psychology, sociology, and adjacent fields as outcomes of developmental processes, institutional regulations and policies, culturally and normatively structured life courses, or empirical accounts. However, such studies have used a wide range of complementary, but often divergent, concepts. This review has two aims. First, we report on the structure that has emerged from scientific life course research by focusing on abstracts from longitudinal and life course studies beginning with the year 2000. Second, we provide a sense of the disciplinary diversity of the field and assess the value of the concept of 'vulnerability' as a heuristic tool for studying human lives. Applying correspondence analysis to 10,632 scientific abstracts, we find a disciplinary divide between psychology and sociology, and observe indications of both similarities of-and differences between-studies, driven at least partly by the data and methods employed. We also find that vulnerability takes a central position in this scientific field, which leads us to suggest several reasons to see value in pursuing theory development for longitudinal and life course studies in this direction.

The rare cancer network: ongoing studies and future strategy.

The Rare Cancer Network (RCN) was formed in the early 1990's to create a global network that could pool knowledge and resources in the studies of rare malignancies whose infrequency prevented both their study with prospective clinical trials. To date, the RCN has initiated 74 studies resulting in 46 peer reviewed publications. The First International Symposium of the Rare Cancer Network took place in Nice in March of 2014. Status updates and proposals for new studies were heard for fifteen topics. Ongoing studies continue for cardiac sarcomas, thyroid cancers, glomus tumors, and adult medulloblastomas. New proposals were presented at the symposium for primary hepatic lymphoma, solitary fibrous tumors, Rosai-Dorfman disease, tumors of the ampulla of Vater, salivary gland tumors, anorectal melanoma, midline nuclear protein in testes carcinoma, pulmonary lymphoepithelioma-like carcinoma, adenoid cystic carcinoma of the trachea, osteosarcomas of the mandible, and extra-cranial hemangiopericytoma. This manuscript presents the abstracts of those proposals and updates on ongoing studies, as well a brief summary of the vision and future of the RCN.

History of the rare cancer network and past research.

Approximately, twenty years ago, the Rare Cancer Network (RCN) was formed in Lausanne, Switzerland, to support the study of rare malignancies. The RCN has grown over the years and now includes 130 investigators from twenty-four nations on six continents. The network held its first international symposium in Nice, France, on March 21-22, 2014. The proceedings of that meeting are presented in two companion papers. This manuscript reviews the history of the growth of the RCN and contains the abstracts of fourteen oral presentations made at the meeting of prior RCN studies. From 1993 to 2014, 74 RCN studies have been initiated, of which 54 were completed, 10 are in progress or under analysis, and 9 were stopped due to poor accrual. Forty-four peer reviewed publications have been written on behalf of the RCN.

Velallisen asema perinnässä ja perintäkulujen merkitys velalliselle

Tutkimuksessa on tarkoitus selvittää velallisen asemaa perinnässä ja perintäkulujen merkitystä. Tutkimus jakautuu teoreettiseen ja empiiriseen osaan, jossa selvitetään teoreettisesti velkaan ja perintään liittyviä käsitteitä ja lainsäädäntöä. Laki saatavien perinnästä sääntelee yleislakina perintätoimintaa riippumatta siitä suorittaako perintää itse velkoja vai perimistoimisto. Lakiin otettiin vuonna 2005 kuluttajasaatavia koskevia perimiskuluja rajoittavat enimmäismäärät, jotka on porrastettu saatavan suuruuden mukaan. Empiirisessä osassa tutkitaan oikeudenkäyntiaineistosta kerätyistä tiedoista perintään kuuluvia osapuolia, perittäviä saatavia ja perimiskuluja. Velallisen asema näyttää olevan riittävän hyvin turvattu oikeusjärjestyksessämme, joskin perimiskulujen ja oikeudenkulujen määrä nousee usein itse perittävää pääomaa suuremmaksi. Rahasaatavien perintää koskevien tapausten määrä käräjäoikeuksissa on kasvanut huomattavasti vuonna 2007. Tällaisia velkomuksia käsiteltiin käräjäoikeuksissa yli 200.000 kappaletta vuonna 2007. Tämän kasvun osaltaan selittää uudeksi velkaongelmien aiheuttajaksi nousemassa olevat pikavipit, joiden määrä kaikista perittävistä saatavista oli noin 10%. Näiden pääomat olivat keskiarvoltaan noin 145 euroa, ja näiden perintäkulut noin kaksinkertaisia verrattuna pääomaan Koko aineistossa perityt pääomat olivat keskiarvoltaan noin 2900 euroa ja perintäkulut noin 270 euroa.
