There is a mismatch between the way public services are designed, and the chronic dilemmas of the welfare state. Through two case studies we show how tool-dependent, instrumental and systems-oriented approaches fall short in tackling these dilemmas, and how the there is a need for a new, relational turn in design. Relational design takes into account interdependencies and dynamic situation of society, and calls for a new design vocabulary that discusses and approaches the relational aspects and opens up for a more situational and sensitive design agency.
Male sex is associated with higher risk of both colonisation and infection with Staphylococcus aureus (S. aureus). However, the role of sex-steroids in colonisation among men is largely unknown. Thus, the aim of this study was to investigate possible associations between circulating sex-steroids and nasal carriage of S. aureus in a general male population. The population-based Tromsø6 study (2007–2008) included 752 males aged 31–87 years with serum sex-steroids measured by liquid chromatography tandem mass spectrometry and two nasal swab samples for the assessment of S. aureus carriage. Multivariable logistic regression models were used to study the association between sex-steroid concentrations and S. aureus persistent nasal carriage (two positive swabs vs. others), while adjusting for potential confounding factors.
S. aureus persistent nasal carriage prevalence was 32%. Among men aged 55 years and above (median age 65 years), there was an inverse dose-response relationship between serum concentration of testosterone and persistent nasal carriage, and carriers had significantly lower mean levels of testosterone (P = 0.028, OR = 0.94 per nmol/l change in testosterone; 95% CI = 0.90–0.98). This association was attenuated when adjusting for body mass index and age (OR = 0.96 per nmol/l change in testosterone; 95% CI = 0.91–1.01). There was no association in the total population. This large population-based study suggests that testosterone levels may be inversely related to S. aureus persistent nasal carriage in older men. Future studies addressing biological mechanisms underlying the male predisposition to S. aureus colonisation and infection may foster preventive interventions that take sex-differences into account.
To establish an antimicrobial stewardship program in the outpatient setting.
Design:
Prescribers of antimicrobials were asked to complete a survey regarding antimicrobial stewardship. We also monitored their compliance with appropriate prescribing practices, which were shared in monthly quality improvement reports.
Setting:
The study was performed at Loyola University Health System, an academic teaching healthcare system in a metropolitan suburban environment.
Participants:
Prescribers of antimicrobials across 19 primary care and 3 immediate- and urgent-care clinics.
Methods:
The voluntary survey was developed using SurveyMonkeyand was distributed via e-mail. Data were collected anonymously. Rates of compliance with appropriate prescribing practices were abstracted from electronic health records and assessed by 3 metrics: (1) avoidance of antibiotics in adult acute bronchitis and appropriate antibiotic treatment in (2) patients tested for pharyngitis and (3) children with upper respiratory tract infections.
Results:
Prescribers were highly knowledgeable about what constitutes appropriate prescribing; verified compliance rates were highly concordant with self-reported rates. Nearly all prescribers were concerned about resistance, but fewer than half believed antibiotics were overprescribed in their office. Among respondents, 74% reported intense pressure from patients to prescribe antimicrobials inappropriately. Immediate- and urgent-care prescribers had higher rates of compliance than primary-care prescribers, and the latter group responded well to monthly reports and online educational resources.
Conclusions:
Intense pressure from patients to prescribe antimicrobials when they are not indicated leads to overprescribing, an effect compounded by the importance of patient satisfaction scores. Compliance reporting improved the number of appropriate antibiotics prescribed in the primary care setting.
The National Institute of Mental Health's Research Domain Criteria (RDoC) framework has prompted a paradigm shift from categorical psychiatric disorders to considering multiple levels of vulnerability for probabilistic risk of disorder. However, the lack of neurodevelopmentally based tools for clinical decision making has limited the real-world impact of the RDoC. Integration with developmental psychopathology principles and statistical methods actualize the clinical implementation of RDoC to inform neurodevelopmental risk. In this conceptual paper, we introduce the probabilistic mental health risk calculator as an innovation for such translation and lay out a research agenda for generating an RDoC- and developmentally informed paradigm that could be applied to predict a range of developmental psychopathologies from early childhood to young adulthood. We discuss methods that weigh the incremental utility for prediction based on intensity and burden of assessment, the addition of developmental change patterns, considerations for assessing outcomes, and integrative data approaches. Throughout, we illustrate the risk calculator approach with different neurodevelopmental pathways and phenotypes. Finally, we discuss real-world implementation of these methods for improving early identification and prevention of developmental psychopathology. We propose that mental health risk calculators can build a needed bridge between the RDoC multiple units of analysis and developmental science.
Aberrant anticipation of motivational salient events and processing of outcome evaluation in striatal and prefrontal regions have been suggested to underlie psychosis. Altered glutamate levels have likewise been linked to schizophrenia. Glutamatergic abnormalities may affect the processing of motivational salience and outcome evaluation. It remains unresolved, whether glutamatergic dysfunction is associated with the coding of motivational salience and outcome evaluation in antipsychotic-naïve patients with first-episode psychosis.
Methods
Fifty-one antipsychotic-naïve patients with first-episode psychosis (22 ± 5.2 years, female/male: 31/20) and 52 healthy controls (HC) matched on age, sex, and parental education underwent functional magnetic resonance imaging and magnetic resonance spectroscopy (3T) in one session. Brain responses to motivational salience and negative outcome evaluation (NOE) were examined using a monetary incentive delay task. Glutamate levels were estimated in the left thalamus and anterior cingulate cortex using LCModel.
Results
Patients displayed a positive signal change to NOE in the caudate (p = 0.001) and dorsolateral prefrontal cortex (DLPFC; p = 0.003) compared to HC. No group difference was observed in motivational salience or in levels of glutamate. There was a different association between NOE signal in the caudate and DLPFC and thalamic glutamate levels in patients and HC due to a negative correlation in patients (caudate: p = 0.004, DLPFC: p = 0.005) that was not seen in HC.
Conclusions
Our findings confirm prior findings of abnormal outcome evaluation as a part of the pathophysiology of schizophrenia. The results also suggest a possible link between thalamic glutamate and NOE signaling in patients with first-episode psychosis.
Negative symptoms of schizophrenia remain a major therapeutic challenge. The progress in the conceptualization and assessment is not yet fully reflected by treatment research. Nevertheless, there is a growing evidence base regarding the effects of biological and psychosocial interventions on negative symptoms. The importance of the distinction between primary and secondary negative symptoms for treatment selection might seem evident, but the currently available evidence remains limited. Good clinical practice is recommended for the treatment of secondary negative symptoms. Antipsychotic treatment should be optimized to avoid secondary negative symptoms due to side effects and due to positive symptoms. For most available interventions, further evidence is needed to formulate sound recommendations for primary, persistent, or predominant negative symptoms.
However, based on currently available evidence recommendations for the treatment of undifferentiated negative symptoms (including both primary and secondary negative symptoms) are provided. Although it has proven difficult to formulate an evidence-based recommendation for the choice of an antipsychotic, a switch to a second-generation antipsychotic should be considered for patients who are treated with a first-generation antipsychotic. Antidepressant add-on to antipsychotic treatment is an option. Social skills training is recommended as well as cognitive remediation for patients who also show cognitive impairment. Exercise interventions also have shown promise. Finally, access to treatment and to psychosocial rehabilitation should be ensured for patients with negative symptoms. Overall, there is definitive progress in the field, but further research is clearly needed to develop specific treatments for negative symptoms.
Improved survival has led to a growing population of adults with congenital heart disease (CHD), followed by numerous reports of late complications. Liver disease is a known complication in some patients, with most studies focusing on Fontan associated liver disease. Whether liver disease also exists in other patients with CHD is not fully investigated. Elevated central venous pressure is considered pivotal in the development of liver disease in Fontan associated liver disease, and other patients with alterations in central venous pressure may also be at risk for developing liver fibrosis. We wanted to see if liver fibrosis is present in patients with tetralogy of Fallot. Many patients with tetralogy of Fallot have severe pulmonary regurgitation, which can lead to elevated central venous pressure. Patients with tetralogy of Fallot may be at risk of developing liver fibrosis.
Materials and methods:
Ten patients (24–56 years) with tetralogy of Fallot and pulmonary regurgitation were investigated for liver fibrosis. All patients were examined with magnetic resonance elastography of liver, hepatobiliary iminodiacetic acid scan, indocyanine green elimination by pulse spectrophotometry, elastography via FibroScan, abdominal ultrasound including liver elastography, and blood samples including liver markers.
Results:
Three out of ten patients had findings indicating possible liver fibrosis. Two of these had a liver biopsy performed, which revealed fibrosis stage 1 and 2, respectively. The same three patients had an estimated elevated central venous pressure in previous echocardiograms.
Conclusions:
Mild liver fibrosis was present in selected patients with tetralogy of Fallot and may be related to elevated central venous pressure.
During the last decades, a renewed interest for negative symptoms (NS) was brought about by the increased awareness that they interfere severely with real-life functioning, particularly when they are primary and persistent.
Methods
In this guidance paper, we provide a systematic review of the evidence and elaborate several recommendations for the conceptualization and assessment of NS in clinical trials and practice.
Results
Expert consensus and systematic reviews have provided guidance for the optimal assessment of primary and persistent negative symptoms; second-generation rating scales, which provide a better assessment of the experiential domains, are available; however, NS are still poorly assessed both in research and clinical settings.
This European Psychiatric Association (EPA) guidance recommends the use of persistent negative symptoms (PNS) construct in the context of clinical trials and highlights the need for further efforts to make the definition of PNS consistent across studies in order to exclude as much as possible secondary negative symptoms. We also encourage clinicians to use second-generation scales, at least to complement first-generation ones.
The EPA guidance further recommends the evidence-based exclusion of several items included in first-generation scales from any NS summary or factor score to improve NS measurement in research and clinical settings. Self-rated instruments are suggested to further complement observer-rated scales in NS assessment.
Several recommendations are provided for the identification of secondary negative symptoms in clinical settings.
Conclusions
The dissemination of this guidance paper may promote the development of national guidelines on negative symptom assessment and ultimately improve the care of people with schizophrenia.
Donkeys have been used as working animals for transport and farm activities worldwide. Recently, in European countries, there has been an increasing interest in donkeys due to their use as pets, onotherapy or milk production. During 2014–2016, a countrywide survey was conducted to determine prevalence and risk factors of principal helminth infections in 1775 donkeys in 77 Italian farms. A questionnaire on management and parasite control practices was filled out for each farm. Faecal samples were examined using a modified McMaster technique, a centrifugation/flotation method and a sedimentation technique. Pooled coprocultures were performed for differentiation of strongylid eggs. Strongyles were the most common parasites detected (84.9%), followed by Dictyocaulus arnfieldi (6.9%), Oxyuris equi (5.8%), Parascaris spp. (3.6%), Anoplocephala spp. (1.0%), Strongyloides westeri (0.3%). Coprocultures revealed an omnipresence of cyathostomins (100%), followed by Strongylus vulgaris (31.0%), Poteriostomum spp. (25.0%), Triodontophorus spp. (9.0%), Strongylus edentatus (7.0%), Strongylus equinus (5.0%). Logistic regression analysis identified breed, co-pasture with horses, living area, herd size and number of treatments as significantly associated with strongyles. Sex, age, living area and herd size were significantly associated with Parascaris spp. Dictyocaulus arnfieldi was significantly associated with sex, grass, co-pasture with horses, living area and herd size. Strongylus vulgaris was significantly associated with living area and herd size. The mean number of anthelmintic treatments/year was 1.4; most of the donkeys (71.8%) were dewormed using an ivermectin drug. It is important to design parasite programs to specifically address both D. arnfieldi and S. vulgaris in donkeys, and this is especially important if donkeys co-graze with horses.
Behavioural design is a critical means to address challenges surrounding human behaviour. However, practitioners and researcher face difficulties in synthesising relevant perspectives from across fields as behavioural challenges are complex and multi-dimensional. Taking a theory-building approach, this study explore how expert behavioural designers navigate in this complex design space by examining the creative outcome of their current ideation practice. The findings reveal that the designers favour ‘holding’ out of the four identified ideation patterns: holding, shifting, pairing, and mixing.
Current sea-level rise partly stems from increased surface melting and meltwater runoff from the Greenland ice sheet. Multi-year snow, also known as firn, covers about 80% of the ice sheet and retains part of the surface meltwater. Since the firn cold content integrates its physical and thermal characteristics, it is a valuable tool for determining the meltwater-retention potential of firn. We use gap-filled climatological data from nine automatic weather stations in the ice-sheet accumulation area to drive a surface-energy-budget and firn model, validated against firn density and temperature observations, over the 1998–2017 period. Our results show a stable top 20 m firn cold content (CC20) at most sites. Only at the lower-elevation Dye-2 site did CC20 decrease, by 24% in 2012, before recovering to its original value by 2017. Heat conduction towards the surface is the main process feeding CC20 at all nine sites, while CC20 reduction occurs through low-cold-content fresh-snow addition at the surface during snowfall and latent-heat release when meltwater refreezes. Our simulations suggest that firn densification, while reducing pore space for meltwater retention, increases the firn cold content, enhances near-surface meltwater refreezing and potentially sets favourable conditions for ice-slab formation.
Recent developments of the Danish Health Care Sector have created new, large scale specialised units with standardized trajectories for patients undergoing diagnostic assessment. In the present study, the assessment process is defined as the psychosocial process through which clinical knowledge about the patients’ illness is collected and evaluated.
A group of patients, the complex patients, present diffuse symptoms and may have rivalling illnesses and needs help from various specialised functions. This group of patients can have problems getting their diffuse symptoms categorised and legitimised.
The aim of the study is to gain knowledge about how complex patients are diagnostically assessed in specialised units. The focus will be on organizational, professionals and patient perspectives. Knowledge about diagnostic assessment is important because it is a great individual, social and economic problem that complex patients are circulated in the health care system without a proper diagnosis and treatment.
The diagnostic process will be examined in two specialised units, a sclerosis unit and a mental health unit. Both clinics are specialised in assessment of patients who have complex problems. The clinical experience is that these units often get patients referred, which have not been possible to assess anywhere else in the system.
The sample will consist of 20 patients, who are categorized as complex patients, as well as the healthcare professionals who are affiliated with the patients. Data will be collected by means of ethnographic fieldwork, interviews, audio recordings of consultations, collection of journals and written material from the units.
Many new approaches have been developed to treat borderline personality disorder (BPD) by means of psychotherapy. Though there is a clear research trend towards short-interventions, the evidence from randomised controlled trials (RCT) on longer-term programmes still accumulates. On the one hand, well-established treatments like Dialectical Behavior Therapy (DBT) or Mentalisation-Based Treatment (MBT) are now subject to real-world effectiveness studies; on the other hand, new dynamic approaches have been studied, lasting longer than 6 months.
Objectives
We are currently updating the cochrane Collaboration review on psychological interventions for BPD. First findings on the effects of longer-term psychotherapies will be presented.
Methods
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) according to cochrane collaboration standards. Any randomized comparisons of psychological interventions versus unspecific control interventions, waitlist or specific psychotherapeutic interventions in adult BPD patients were eligible. Primary outcomes were BPD core pathology as depicted by DSM criteria. Secondary outcomes included associated pathology, i.e., depression and anxiety, general psychopathology severity and functioning as well as tolerability and safety. Two researchers selected trials, assessed quality and extracted data independently.
Results
The current evidence of longer-term psychological interventions in general, and the types of interventions for which RCT evidence is available will be evaluated and critically discussed.

Though prescription is off-lable, “atypical” or “second-generation” antipsychotics (SGAs) are prevalently given to borderline personality disorder (BPD) patients. They have also been the focus of research on pharmacological agents in BPD in recent years, as the previous version of the relating cochrane systematic review shows.
Objectives
We are currently updating this cochrane systematic review on pharmacological interventions for BPD. First findings on the up-to-date evidence relating to SGAs will be presented.
Methods
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) according to cochrane collaboration standards. Any randomized comparisons of drug vs. placebo, drug vs. drug, or drug vs. a combination of drugs in adult BPD patients were eligible. Primary outcomes were BPD core pathology as depicted by DSM criteria. Secondary outcomes included associated pathology, i.e., depression and anxiety, general psychopathology severity and functioning as well as tolerability and safety. Two researchers selected trials, assessed quality and extracted data independently.
Results
The current RCT evidence on SGAs in BPD will be presented, and their use in everyday clinical care settings will critically be discussed.

Alzheimer's disease (AD), the most common disease causing dementia, is linked to increased mortality. However, the effect of antipsychotic use on specific causes of mortality has not yet been investigated thoroughly.
Methods
Utilizing the Danish nationwide registers, we defined a cohort of patients diagnosed with AD. Utilizing separate Cox regressions for specific causes of mortality, we investigated the effects of cumulative antipsychotic dosage after diagnosis and current antipsychotic exposure in the time period 2000–2011.
Results
In total, 45,894 patients were followed for 3,803,996 person-years. A total of 6129 cardiovascular related deaths, 2088 cancer related deaths, 1620 infection related deaths, and 28 intentional self-harm related deaths are presented. Current antipsychotic exposure increased mortality rate with HR between 1.92 and 2.31 for cardiovascular, cancer, and infection related death. Cumulative antipsychotic dosages were most commonly associated with increased rates of mortality for cardiovascular and infection as cause of death, whereas the associations were less clear with cancer and intentional self-harm as cause of death.
Conclusions
We showed that cumulative antipsychotic drug dosages increased mortality rates for cardiovascular and infection as cause of death. These findings highlight the need for further investigations of long-term effects of treatment and of possible sub-groups who could benefit from treatment.
Unipolar depression is a public health problem and is the most common psychiatric disorder among people with long-term sick leave in Denmark. Patients with unipolar depression are often associated with deficits in cognitive function long after the affective symptoms have disappeared. This could explain the long-term sick leave among patients suffering from unipolar depression. Computer-based cognitive training has been used to increase cognitive function in other patient groups.
Objectives
It is unknown whether cognitive functions are improved in patients with depression by help of a cognitive computer program. Further we investigate whether this intervention shortens sick leave.
Aims
To investigate whether a computer-based cognitive training group present a higher score in cognitive function after training and return to their employment earlier compared to the control group.
Methods
The study includes patients who have been admitted because of depression, but are finished with their treatment. When the patients are discharged, they will be randomizes into two groups and evaluated on their cognitive function. Only one of the two groups will receive computer-based cognitive training. After 12 week the two groups’ cognitive function will be compared. Furthermore there is a six-month follow up, to show if or when the participants have returned to work.
Results
The results will be presented at the EPA March 2016 in Madrid.
Conclusion
Based on the results of study it is our intention to conclude whether or not to implement computer-based cognitive training in treatment of patients with depression.

Borderline personality disorder (BPD) is a common and disabling personality disorder associated with difficulties in controlling emotions and impulses, self-injury, feelings of emptiness and abandonment. It is associated with problems in many areas of life, most notably relationships. Psychotherapy is the first-line treatment for people with borderline personality disorder widely used; however, the evidence is not thoroughly investigated. In addition, several specific short-term interventions have been developed during the last decades.
Objectives
We are currently updating this cochrane collaboration review on psychological interventions for BPD. First findings on the up-to-date evidence relating to short-term psychological interventions will be presented.
Methods
We conducted a cochrane systematic review and meta-analysis of randomized controlled trials (RCTs). Any randomized comparisons of psychological interventions versus unspecific control interventions, waitlist or specific psychotherapeutic interventions in adult BPD patients were eligible. Primary outcomes were BPD core pathology as depicted by DSM criteria. Secondary outcomes included depression, anxiety, general psychopathology, dropouts and adverse events. Two independent researchers selected trials, assessed quality and extracted data independently.
Results
The current evidence of short-term psychological interventions in general and the different types of interventions for which RCT evidence is currently available will be evaluated.

The western societies have a rapidly aging population and an increasing number of elderly with alcohol use disorders.
Objective
The purpose of the elderly study is to develop and test an outpatient behavior therapy program for people with an alcohol use disorders.
Aim of this abstract
To investigate the association between ages, gender, drinking pattern and psychology distress.
Method
The study is a randomized study expected to enroll and treat 1000 participants aged 60+ years before April 2017; 200 in USA; 400 in Germany and 400 in Denmark. To be included in the study the participants have to fulfil the DSM-5 criteria for alcohol use disorder. All participants are examined at baseline, and at four follow up interviews. After the baseline interview all participants are randomized to Motivational Enhancement Therapy (MET); or MET followed by 8 weeks of counseling based on the Community Reinforcement Approach (CRA) with a module added to address problems relevants to elderly people.
Results
The presentation will include baseline characteristics of the Danish participants including demographics, expectations to treatment, history of drinking in the last 90 days before baseline and their psychological distress. We have now enrolled 259 participants in the Danish database. We expect to present results from 320 patients.
Conclusion
The data will present information about the profile of 60+ years’ individuals seeking treatment for alcohol use disorder, and thereby provide knowledge about which characteristics that may be important when planning treatment for this age group.

Despite the relatively weak evidence base, individuals with borderline personality disorder are often treated with pharmacological interventions. Amongst the drugs, which have shown most promise, are mood stabilizers, which were one of the two drug classes with the most beneficial effects in a previous cochrane review though the robustness of findings was described as low (Stoffers et al., 2010). Here we present data on the latest evidence for mood stabilizers based on an updated cochrane review currently underway.
Methods
A systematic review and meta-analysis of randomized controlled trials was conducted. All randomized comparisons of drug vs. placebo, drug vs. drug, or drug vs. a combination of drugs in adult BPD patients were eligible for inclusion. Outcomes comprised BPD core pathology as depicted by DSM criteria, associated pathology, i.e., depression and anxiety, general measures of overall psychopathology severity, tolerability, and adverse effects. Two researchers selected trials, assessed quality and extracted data independently.
Results
Only a limited number of additional trials using mood stabilizers was identified since the publication of the last cochrane review, mainly utilizing Sodium Valproate. This added to the evidence base for mood stabilizers though the overall evidence remains very limited.
Conclusion
Mood stabilizers show some initial evidence for their effectiveness in borderline personality disorder. However, these have to be replicated before wider conclusions can be drawn for clinical practice.
