Effectiveness of integrated psychological therapy (IPT) for schizophrenia patients: a research update

Standardized recovery criteria go beyond symptom remission and put special emphasis on personal and social functioning in residence, work, and leisure. Against this background, evidence-based integrated approaches combining cognitive remediation with social skills therapy show promise for improving functional recovery of schizophrenia patients. Over the past 30 years, research groups in 12 countries have evaluated integrated psychological therapy (IPT) in 36 independent studies. IPT is a group therapy program for schizophrenia patients. It combines neurocognitive and social cognitive interventions with social skills and problem-solving approaches. The aim of the present study was to update and integrate the growing amount of research data on the effectiveness of IPT. We quantitatively reviewed the results of these 36 studies, including 1601 schizophrenia patients, by means of a meta-analytic procedure. Patients undergoing IPT showed significantly greater improvement in all outcome variables (neurocognition, social cognition, psychosocial functioning, and negative symptoms) than those in the control groups (placebo-attention conditions and standard care). IPT patients maintained their mean positive effects during an average follow-up period of 8.1 months. They showed better effects on distal outcome measures when all 5 subprograms were integrated. This analysis summarizes the broad empirical evidence indicating that IPT is an effective rehabilitation approach for schizophrenia patients and is robust across a wide range of sample characteristics as well as treatment conditions. Moreover, the cognitive and social subprograms of IPT may work in a synergistic manner, thereby enhancing the transfer of therapy effects over time and improving functional recovery.

Human adrenal corticocarcinoma NCI-H295R cells produce more androgens than NCI-H295A cells and differ in 3beta-hydroxysteroid dehydrogenase type 2 and 17,20 lyase activities

The human adrenal cortex produces mineralocorticoids, glucocorticoids, and androgens in a species-specific, hormonally regulated, zone-specific, and developmentally characteristic fashion. Most molecular studies of adrenal steroidogenesis use human adrenocortical NCI-H295A and NCI-H295R cells as a model because appropriate animal models do not exist. NCI-H295A and NCI-H295R cells originate from the same adrenocortical carcinoma which produced predominantly androgens but also smaller amounts of mineralocorticoids and glucocorticoids. Research data obtained from either NCI-H295A or NCI-H295R cells are generally compared, although for the same experiments no direct comparison between the two cell lines has been performed. Therefore, we compared the steroid profile and the expression pattern of important genes involved in steroidogenesis in both cell lines. We found that steroidogenesis differs profoundly. NCI-H295A cells produce more mineralocorticoids, whereas NCI-H295R cells produce more androgens. Expression of the 3beta-hydroxysteroid dehydrogenase (HSD3B2), cytochrome b5, and sulfonyltransferase genes is higher in NCI-H295A cells, whereas expression of the cytochrome P450c17 (CYP17), 21-hydroxylase (CYP21), and P450 oxidoreductase genes does not differ between the cell lines. We found lower 3beta-hydroxysteroid dehydrogenase type 2 but higher 17,20-lyase activity in NCI-H295R cells explaining the 'androgenic' steroid profile for these cells and resembling the zona reticularis of the human adrenal cortex. Both cell lines were found to express the ACTH receptor at low levels consistent with low stimulation by ACTH. By contrast, both cell lines were readily stimulated by 8Br-cAMP. The angiotensin type 1 receptor was highly expressed in NCI-H295R than NCI-H295A cells and angiotensin II stimulated steroidogenesis in NCI-H295R but not NCI-H295A cells. Our data suggest that comparative studies between NCI-H295A and NCI-H295R cells may help find important regulators of mineralocorticoid or androgen biosynthesis.

Bevezető: utak és úton lévők

A kvalitatív módszerekkel nyert kutatási eredményeink értelmezése során a transznacionális tér, a transznacionális és az etnikai migráció elméleti és szemléleti kereteit egyaránt figyelembe vettük. Az általunk vizsgált migrációs folyamatok transznacionális térben zajlanak, és a transznacionális irodalomban leírt migráns élethelyzetek, gyakorlatok – különböző nemzetállamokban elhelyezkedő lokalitásokhoz való egyidejű, bár eltérő intenzitású kötődés, kapcsolatok – több példájával is találkoztunk. Ludger Pries nyomán a transznacionális migrációt és a transznacionális migráns alakját olyan ideáltípusnak tekintettük, amelyhez az egyes migráns utak és helyzetek csupán közelítenek, és empirikus eredményeink alapján azt mondhatjuk, hogy a valóban plurilokális, vagyis a két helyhez való egyidejű, intenzív és tartós kötődés s az ehhez kapcsolódó gyakorlatok csupán a migránsok kisebbségét, illetve a migrációs életpályák egy-egy szakaszát jellemzik. A vizsgált migrációs folyamatokban az etnicitás strukturális tényezőként és a migráns tapasztalatok értelmezési kereteként egyaránt perdöntő szerepet játszik. Az etnikai migráció szakirodalomban tárgyalt mindhárom magyarázó modellje – az anyaországba való hazatérés, a gazdasági okokból való, illetve a kisebbségi létben elszenvedett sérelmek által ösztönzött migráció – alkalmas a migrációt kiváltó és mozgató okok elemzésére, a migráns narratívák értelmezésére, azt azonban nem állíthatjuk, hogy bármelyikük kizárólagos érvényre tehet szert. Más kutatókhoz hasonlóan Rogers Brubaker meghatározását tartjuk a leginkább gyümölcsözőnek, aki az etnikai migráció tág értelmezését használva minden olyan vándorlási folyamatot etnikai migrációnak tekint, amelyben az etnicitás kulturális és szimbolikus tőkeként szabályozó szerepet játszik. This special issue of Tér és Társadalom presents some results of an international research project carried out by researchers from Switzerland, Hungary and Serbia between 2010 and 2012. The topic of the research was “Integrating (Trans-)national Migrants in Transition States” (TRANSMIG) and was financed by the Swiss National Science Foundation (SNSF). The research aimed to explore and interpret migration flows from the Vojvodina (Serbia) to Hungary and from ex-Yugoslav republics to the Vojvodina. In the first period of the last twenty years, wars which contributed to the disintegration of Yugoslavia and the formation of new national states have caused migration flows. After the change of the millennium, educational migration of Vojvodina Hungarian youth can be considered the most important migratory movement from the Vojvodina to Hungary. Labour (economic) migration also occurs, but this cannot be understood as a one-way movement, since in the Hungarian–Serbian border zone migrants from the Vojvodina who already resettled to Hungary commute to the Vojvodina. While interpreting the qualitative research data the theoretical frameworks and approaches of transnational space, transnationalism and ethnic migration were taken into consideration. The migration movement in question occurs in a transnational social space where migrants are in constant motion. By their movements and actions that space is continually recreated. With Ludger Pries we see a transnational migrant as an ideal type to whom individual migratory movements and positions only approximate. Based on our empirical results we can conclude that real pluri-local, intensive and long-lasting bonding to two places at the same time and the relating practices only characterise a minority of migrants and certain sections of migratory careers. In the migration processes studied, ethnicity as a term is needed as a “structural factor” and frame of interpretation to approach migrant experiences. All three explanatory models for ethnic migration – return migration, economic migration, migration motivated by grievances suffered in a minority situation – are suitable to analyse the reasons that initiated migration and kept it in motion. They are helpful in interpreting migrant narratives. However, none of the reasons can claim exclusive validity. Agreeing with other researchers, we find Roger Brubaker’s definition the most useful: Ethnic migration should be comprehended in a broad sense. In addition, every migration can be considered as “ethnically” motivated where ethnicity plays a dominant role as a cultural and symbolic capital.

An Undisclosed Story of Roses: Church, State and Nation in Contemporary Georgia

I will attempt to problematize the typologies of nationalism when applied to the Georgian context, particularly in relationship to nationalism of President Mikheil Saakashvili. I will argue that the state-driven nationalism of post-Rose Revolution government was a hybrid form of ethno-cultural and civic which had elements of ethnic particularism towards the Orthodox Church. By reflecting on the growing assistance of Western institutions to Georgia, I will problematize the extent to which the rise of American and European involvement in the region reinforced the perceptions of the “self” and the “other” among the religious elites since the Rose Revolution. By presenting field research data (interviews) gathered in 23 eparchies and perishes with religious clerics in 7 regions of Georgia, I will argue that religious nationalism in Georgia strengthened not in response to but as an outcome of President Saakashvili’s policies towards the church, and partially as a reaction to the growing dissatisfaction with Western institutions working in Georgia and Western governments’ response to the Russo-Georgian War of 2008. By reflecting on empirical material, the paper attempts to problematize an understanding of religious nationalism as a social movement, an instance of cultural autonomy and a source of identity (Friedland 2001). In response, I suggest viewing religious nationalism in post-communist Georgia as medium of material and political interests

The impact of environmental enrichment on the outcome variability and scientific validity of laboratory animal studies.

It has been widely accepted for some time that species-appropriate environmental enrichment is important for the welfare of research animals, but its impact on research data initially received little attention. This has now changed, as the use of enrichment as one element of routine husbandry has expanded. In addition to its use in the care of larger research animals, such as nonhuman primates, it is now being used to improve the environments of small research animals, such as rodents, which are used in significantly greater numbers and in a wide variety of studies. Concern has been expressed that enrichment negatively affects both experimental validity and reproducibility. However, when a concise definition of enrichment is used, with a sound understanding of the biology and behaviour of the animal as well as the research constraints, it becomes clear that the welfare of research animals can be enhanced through environmental enrichment without compromising their purpose. Indeed, it is shown that the converse is true: the provision of suitable enrichment enhances the well-being of the animal, thereby refining the animal model and improving the research data. Thus, the argument is made that both the validity and reproducibility of the research are enhanced when proper consideration is given to the research animal's living environment and the animal's opportunities to express species-typical behaviours.

The International Surface Pressure Databank version 2

The International Surface Pressure Databank (ISPD) is the world's largest collection of global surface and sea-level pressure observations. It was developed by extracting observations from established international archives, through international cooperation with data recovery facilitated by the Atmospheric Circulation Reconstructions over the Earth (ACRE) initiative, and directly by contributing universities, organizations, and countries. The dataset period is currently 1768–2012 and consists of three data components: observations from land stations, marine observing systems, and tropical cyclone best track pressure reports. Version 2 of the ISPD (ISPDv2) was created to be observational input for the Twentieth Century Reanalysis Project (20CR) and contains the quality control and assimilation feedback metadata from the 20CR. Since then, it has been used for various general climate and weather studies, and an updated version 3 (ISPDv3) has been used in the ERA-20C reanalysis in connection with the European Reanalysis of Global Climate Observations project (ERA-CLIM). The focus of this paper is on the ISPDv2 and the inclusion of the 20CR feedback metadata. The Research Data Archive at the National Center for Atmospheric Research provides data collection and access for the ISPDv2, and will provide access to future versions.

The role of metabotropic glutamate receptor 5 in the pathogenesis of mood disorders and addiction: combining preclinical evidence with human Positron Emission Tomography (PET) studies.

In the present review, we deliver an overview of the involvement of metabotropic glutamate receptor 5 (mGluR5) activity and density in pathological anxiety, mood disorders and addiction. Specifically, we will describe mGluR5 studies in humans that employed Positron Emission Tomography (PET) and combined the findings with preclinical animal research. This combined view of different methodological approaches-from basic neurobiological approaches to human studies-might give a more comprehensive and clinically relevant view of mGluR5 function in mental health than the view on preclinical data alone. We will also review the current research data on mGluR5 along the Research Domain Criteria (RDoC). Firstly, we found evidence of abnormal glutamate activity related to the positive and negative valence systems, which would suggest that antagonistic mGluR5 intervention has prominent anti-addictive, anti-depressive and anxiolytic effects. Secondly, there is evidence that mGluR5 plays an important role in systems for social functioning and the response to social stress. Finally, mGluR5's important role in sleep homeostasis suggests that this glutamate receptor may play an important role in RDoC's arousal and modulatory systems domain. Glutamate was previously mostly investigated in non-human studies, however initial human clinical PET research now also supports the hypothesis that, by mediating brain excitability, neuroplasticity and social cognition, abnormal metabotropic glutamate activity might predispose individuals to a broad range of psychiatric problems.

Does published orthodontic research account for clustering effects during statistical data analysis?

In orthodontics, multiple site observations within patients or multiple observations collected at consecutive time points are often encountered. Clustered designs require larger sample sizes compared to individual randomized trials and special statistical analyses that account for the fact that observations within clusters are correlated. It is the purpose of this study to assess to what degree clustering effects are considered during design and data analysis in the three major orthodontic journals. The contents of the most recent 24 issues of the American Journal of Orthodontics and Dentofacial Orthopedics (AJODO), Angle Orthodontist (AO), and European Journal of Orthodontics (EJO) from December 2010 backwards were hand searched. Articles with clustering effects and whether the authors accounted for clustering effects were identified. Additionally, information was collected on: involvement of a statistician, single or multicenter study, number of authors in the publication, geographical area, and statistical significance. From the 1584 articles, after exclusions, 1062 were assessed for clustering effects from which 250 (23.5 per cent) were considered to have clustering effects in the design (kappa = 0.92, 95 per cent CI: 0.67-0.99 for inter rater agreement). From the studies with clustering effects only, 63 (25.20 per cent) had indicated accounting for clustering effects. There was evidence that the studies published in the AO have higher odds of accounting for clustering effects [AO versus AJODO: odds ratio (OR) = 2.17, 95 per cent confidence interval (CI): 1.06-4.43, P = 0.03; EJO versus AJODO: OR = 1.90, 95 per cent CI: 0.84-4.24, non-significant; and EJO versus AO: OR = 1.15, 95 per cent CI: 0.57-2.33, non-significant). The results of this study indicate that only about a quarter of the studies with clustering effects account for this in statistical data analysis.

From big smartphone data to worldwide research: The Mobile Data Challenge

This paper presents an overview of the Mobile Data Challenge (MDC), a large-scale research initiative aimed at generating innovations around smartphone-based research, as well as community-based evaluation of mobile data analysis methodologies. First, we review the Lausanne Data Collection Campaign (LDCC), an initiative to collect unique longitudinal smartphone dataset for the MDC. Then, we introduce the Open and Dedicated Tracks of the MDC, describe the specific datasets used in each of them, discuss the key design and implementation aspects introduced in order to generate privacy-preserving and scientifically relevant mobile data resources for wider use by the research community, and summarize the main research trends found among the 100+ challenge submissions. We finalize by discussing the main lessons learned from the participation of several hundred researchers worldwide in the MDC Tracks.

Validation and reclassification of MGAP and GAP in hospital settings using data from the Trauma Audit and Research Network.

BACKGROUND Recently, two simple clinical scores were published to predict survival in trauma patients. Both scores may successfully guide major trauma triage, but neither has been independently validated in a hospital setting. METHODS This is a cohort study with 30-day mortality as the primary outcome to validate two new trauma scores-Mechanism, Glasgow Coma Scale (GCS), Age, and Pressure (MGAP) score and GCS, Age and Pressure (GAP) score-using data from the UK Trauma Audit and Research Network. First, an assessment of discrimination, using the area under the receiver operating characteristic (ROC) curve, and calibration, comparing mortality rates with those originally published, were performed. Second, we calculated sensitivity, specificity, predictive values, and likelihood ratios for prognostic score performance. Third, we propose new cutoffs for the risk categories. RESULTS A total of 79,807 adult (≥16 years) major trauma patients (2000-2010) were included; 5,474 (6.9%) died. Mean (SD) age was 51.5 (22.4) years, median GCS score was 15 (interquartile range, 15-15), and median Injury Severity Score (ISS) was 9 (interquartile range, 9-16). More than 50% of the patients had a low-risk GAP or MGAP score (1% mortality). With regard to discrimination, areas under the ROC curve were 87.2% for GAP score (95% confidence interval, 86.7-87.7) and 86.8% for MGAP score (95% confidence interval, 86.2-87.3). With regard to calibration, 2,390 (3.3%), 1,900 (28.5%), and 1,184 (72.2%) patients died in the low, medium, and high GAP risk categories, respectively. In the low- and medium-risk groups, these were almost double the previously published rates. For MGAP, 1,861 (2.8%), 1,455 (15.2%), and 2,158 (58.6%) patients died in the low-, medium-, and high-risk categories, consonant with results originally published. Reclassifying score point cutoffs improved likelihood ratios, sensitivity and specificity, as well as areas under the ROC curve. CONCLUSION We found both scores to be valid triage tools to stratify emergency department patients, according to their risk of death. MGAP calibrated better, but GAP slightly improved discrimination. The newly proposed cutoffs better differentiate risk classification and may therefore facilitate hospital resource allocation. LEVEL OF EVIDENCE Prognostic study, level II.
