The ability of two isolates of the nematode-trapping fungus Duddingtonia flagrans to reduce the numbers of gastrointestinal nematode larvae on herbage was tested in three plot studies. Artificially prepared cow pats containing Ostertagia ostertagi eggs, with and without fungal spores, were deposited on pasture plots two or three times during the grazing season in 1995, 1996 and 1997. The herbage around each pat was sampled fortnightly over a period of 2 months and the number of infective larvae was recorded. At the end of the sampling period, the remainder of the faecal pats was collected to determine the wet weight, dry weight, and content of organic matter. The infective larvae remaining in the pats were extracted. Faecal cultures showed that both fungal isolates significantly reduced the number of infective larvae. Significantly fewer larvae were recovered from herbage surrounding fungus-treated pats compared with control pats in all three experiments, reflecting the ability of the fungus to destroy free-living larval stages in the faecal pat environment. After 8 weeks on pasture there were no differences between control and fungus-treated pats with respect to wet weight, dry weight, and organic matter content. This indicates that the degradation of faeces was not negatively affected by the presence of the fungus.

A series of experiments on corn meal agar was carried out to evaluate the efficacy of the nematode-trapping fungus Duddingtonia flagrans in different abiotic and biotic conditions which occur in cow pats. Above a concentration of 50 parasitic larvae (L3) cm–2 the fungus produced a maximum of between 500 and 600 nets cm–2 at 20°C in 2 days on the surface of corn meal agar. There were no differences in the trap-producing capacity of three strains of D. flagrans (CIII4, CI3 and Trol A). On agar at 30° and 20°C, the fungus responded to Cooperia oncophora L3 very quickly producing a maximum of trapping nets 1 day after induction. At 10°C, traps were produced slowly starting on day 4 after induction and continued over the following week. Duddingtonia flagrans (CI3) grew at a normal rate at least down to an oxygen concentration of 6 vol.% O2, but it did not grow anaerobically. On agar, D. flagrans (CI3) did not produce trapping nets in an anaerobic atmosphere. Moreover, C. oncophora L3 stopped migration under anaerobic conditions. When the fungal cultures were transferred to a normal aerobic atmosphere, after 1 and 2 weeks under anaerobic conditions, the C. oncophora L3 resumed migrating on the agar and, in response, D. flagrans produced traps in the same amount as when it had not been under anaerobic stress. Under microaerophilic conditions (6 vol.% O2) D. flagrans was able to grow, but the C. oncophora L3 were not able to induce trapping nets in D. flagrans (Trol A) because of larval immobility. But, as under anaerobic conditions, the fungus could return to a nematode-trapping state when transferred to a normal aerobic atmosphere within 1 or 2 weeks if migrating nematodes were present. Under natural conditions in the cow pat it is expected that the fungus will be ready to attack parasitic larvae, when the oxygen tension increases as a result of, for example the activity of the coprophilic fauna. Artificial light giving 3000–3400 Lux on the surface of the agar significantly depressed the growth rate and the production of trapping nets in D. flagrans (CI3). On agar, D. flagrans (CI3) could grow and produce trapping nets at pH levels of 6.3 to 9.3. Net-production has its optimum between pH 7 and 8. On dry faeces mycelial growth was 7–10 mm during a 15 day period while on moist faeces the fungus expanded 15–20 mm during the same period. Based on the parameters investigated, D. flagrans is expected to be especially active in the well aerated surface layer of a cow pat, an area which normally contains a high concentration of infective nematode parasite larvae, but also an area where the temperature can be high and the water content low.

Introduction
Recovery in schizophrenia is both widely accepted and commonly misunderstood. Researchers have described favorable outcomes for schizophrenia for the last 100 years. Nevertheless, many patients, relatives and clinicians view schizophrenia as a disease with an inevitable chronic course, as described by Kraepelin in 1889. The definition and measurement of recovery in schizophrenia have proven to be a difficult task. If defined by the remission of clinical symptoms, we have criteria that are operational, but is symptomatic remission sufficient to describe recovery? If looking at social recovery, outcomes related to recovery e.g., social life, employment or social engagement are not easily measured by reliable independent metrics. Thirdly, recovery can be described as a personal journey rather than a clinical endstate.
ObjectivesThe aim is to present a historical and global overview of 100 years of research in recovery in schizophrenia.
MethodsWe conducted a systematic review and meta-analysis. We included prospective studies with at least 20 years of follow-up on patients with a diagnosis of schizophrenia, and the studies must include face-to-face clinical evaluation. We examined outcome in three nested groups: ‘recovery’, ‘good or better’ (i.e., good and recovery), and ‘moderate or better’ (i.e., moderate, good, and recovery). We used random-effects meta-analysis and meta-regression to examine mean estimates and possible moderators.
ResultsThe overview will start with Bleuler, who described that approximately one third have a good outcome, and end with the most recent meta-analyses on recovery in schizophrenia, presenting both data from our own research and others on the recovery of schizophrenia. Ultimately, we will discuss whether recovery have improved in the last 100 years.
ConclusionsIt is a myth that schizophrenia inevitably has a deteriorating course. Recovery is certainly possible. Schizophrenia remains, however, a severe and complex mental disorder, exhibiting a limited change in prognosis despite more than 100 years of research and efforts to improve treatment.

Introduction
In the Danish social welfare system, few people are homeless solely for economic reasons. In fact, 38% of homeless people suffer from both substance use and a psychiatric disorder, making diagnostic assessment and treatment difficult. This patient group, with dual diagnoses, often fail to receive effective treatment, and the consequences are far reaching and detrimental. A more comprehensive grasp of the history and patterns of substance use in these patients may contribute to improve their treatment.
ObjectivesTo identify the role and patterns of substance use in mentally ill, homeless people.
Methods50 homeless, mentally ill patients are examined in comprehensive interviews, exploring the relationship between substance use, homelessness, and suffering from a mental disorder. The data are analyzed quantitatively as well as qualitatively using thematic analysis.
ResultsPreliminary results indicate that substance use in mentally ill homeless patients is a complex phenomenon. On the one hand, substance use seems to contribute to keep the patient homeless and makes it difficult for the patient to get the necessary psychiatric help. On the other hand, substance use also appear to play an important part in coping with life on the streets by offering some kind of social contact and some relief from a desperate situation.
ConclusionsIt seems that the triad of substance use, mental illness, and homelessness somehow reinforce each other and simultaneously locks the situation. New approaches for disentangling this locked situation and avoiding this ‘Bermuda triangle’ is needed.

The last meal of Tollund Man, a bog body from Early Iron Age Denmark, has been re-examined using new analyses of plant macrofossils, pollen, non-pollen palynomorphs, steroid markers and proteins found in his gut. Some 12–24 hours before he was killed, he ate a porridge containing barley, pale persicaria and flax, and probably some fish. Proteins and eggs from intestinal worms indicate that he was infected with parasites. Although the meal may reflect ordinary Iron Age fare, the inclusion of threshing waste could possibly relate to ritual practices. This re-analysis illustrates that new techniques can throw fresh light on old questions and contribute to understanding life and death in the Danish Early Iron Age.

Introduction
Loneliness affects up to one in every third individual in the western population, and the prevalence is increasing. The literature suggests an increased mortality risk of about 26% when feeling lonely, and an association to some disorders of physical health.
ObjectivesTo assess if loneliness increases the risk of mortality, and if so, if health indicators (hypertension, heart disease, tobacco use, alcoholism, diabetes, obesity, and depression) mediate the association.
MethodsThe design is a community-based prospective cohort study using data from the Swedish Lundby Study. Loneliness is measured in 1997 with a singleton question during interview of a psychiatrist. The outcome is death between 1997 and 2011. Survival analysis is used to estimate the relative risk of mortality. Stratification of potential explanatory covariates examines if any of the health indicators mediate the relationship.
ResultsSignificant more females, unmarried, unemployed, and childless people feel lonely. Moreover, feeling lonely correlates to being smoker or alcoholic when adjusting for age and gender. The statistical work on the survival analysis is still in progress. However, we expect to find a positive correlation between loneliness and mortality corresponding to previous studies, and perhaps to reveal some of the health indicators to cause the association.
ConclusionsWith increasing prevalence, potential health consequences, and a neglected role in the society, loneliness is an important research area.

Introduction
The indoor light environment of hospital wards may affect functions and symptoms that are central to the process of inpatient recovery, including sleep, anxiety, well-being, and mood.
ObjectiveTo assess whether interventions in light improves recovery in hospitalized patients across all medical specialties.
MethodsWe systematically searched and reviewed the literature for RCT's on adult inpatients where any light intervention were compared to standard care or placebo. We reviewed effects of light on various outcomes, and compared differences in administration, timing, color, and intensity of the light.
ResultsWe identified 2330 titles, of which 32 met our predefined selection criteria. Choice of administration, timing, wavelengths, and intensity varied. However, most studies investigated bright light therapy with high intensity and short exposure time, others low-intensity light at night filtered of wavelengths in the blue spectrum, and yet others the use of dawn simulation. Comparators were either placebo lamps with low intensity or regular indoor light. Most studies were performed on psychiatric inpatients, showing that bright light therapy is an effective aid in recovery of major depression. Across medical specialties, several studies reported improved sleep quality during the light intervention. Other studies found a lower rate of delirium. In elderly patients with dementia, studies found light interventions to relieve agitation and confusion.
ConclusionsLight may ease a broad range of symptoms and behaviors across inpatient categories. The intervention is inexpensive, well tolerated, and non-invasive. This study underlines intelligent lighting design as an interesting, yet under-explored, non-pharmaceutical treatment.

Lying behaviour is important for the welfare of the cow. Therefore, reliable electronic devices may improve the management of the cows, and the devices can be used as a tool in research. However, accelerometer-based devices measure acceleration, and an algorithm is therefore necessary for the calculation of lying behaviour. Thus, validation of such devices is imperative prior to use. The objective of this study was to validate the use of the AfiTagII device for measurements of the lying time and frequency of lying bouts of Danish Holstein (DH) and Danish Jersey (DJ) cows in a loose-house system on two different bedding materials. The validation included correlations and linear regression analyses of data collected by the AfiTagII compared with data collected both by direct observations and recordings from a previously validated device (IceQube). In total, 40 cows were observed directly with primiparous and multiparous DJ and DH cows, equally represented. Furthermore, 21 cows were monitored with both AfiTagII and IceQube devices, and data from both devices were collected simultaneously. The devices were attached to the hind leg of the cow. The estimates of the lying time from the AfiTagII device was highly correlated with the recordings from direct observations (r=0.98), and there was a linear relation between these with an intercept equal to 0 and a slope close to 1. The estimates of the lying time from the AfiTagII device was also highly correlated with the IceQube recordings (r=0.94). However, the intercept deviated from 0. The frequency of lying bouts recorded by the AfiTAgII compared to direct observations showed a positive predictive value of 0.96 for lactating cows on the slatted floor and of 0.85 for the dry cows on the deep bedding. The correlations between frequency of lying bouts recorded with the two devices were high (r=0.94), but the intercept deviated from 0. In conclusion, the AfiTagII has a high accuracy for the measurements of lying behaviour in both DH and DJ cows kept on different bedding materials.

Aims.
Literature suggests an association between loneliness and mortality for both males and females. Yet, the linkage of loneliness to mortality is not thoroughly examined, and need to be replicated with a long follow-up time. This study assessed the association between loneliness and mortality, including associations to gender, in 1363 adult swedes.
Methods.This community-based prospective cohort study from the Swedish Lundby Study included 1363 individuals of whom 296 individuals (21.7%) were identified as lonely with use of semi-structured interviews in 1997. The cohort was followed until 2011 and survival analyses were used to estimate the relative risk of death.
Results.Death occurred with an incidence rate of 2.63 per 100 person-years and 2.09 per 100 person-years for lonely and non-lonely individuals, respectively. In crude analysis, loneliness was associated with a significant increased mortality risk of 27% compared with non-lonely individuals [hazard ratio (HR) 1.27; 95% CI 1.01–1.60]. Unadjusted, lonely females had a significant increased risk (HR 1.76; 95% CI 1.31–2.34) and adjusted insignificant increased mortality risk of 27% (HR 1.27; 95% CI 0.92–1.74), compared with non-lonely females. Lonely males were found to have an adjusted significant decreased risk of mortality (HR 0.50; 95% CI 0.32–0.80), compared with non-lonely males.
Conclusions.Findings suggest an association between loneliness and increased risk of mortality and that gender differences may exist, which have not been previously reported. If replicated, our results indicate that loneliness may have differential physical implications in some subgroups. Future studies are needed to further investigate the influence of gender on the relationship.

Background
Controversy exists regarding whether people in the community who meet criteria for a non-psychotic mental disorder diagnosis are necessarily in need of treatment. Some have argued that these individuals require treatment and that policy makers need to develop outreach programs for them, whereas others have argued that the current epidemiologic studies may be diagnosing symptoms of distress that in many cases are self-limiting and likely to remit without treatment. All prior studies that have addressed this issue have been cross-sectional. We examined the longitudinal outcomes of individuals with depressive, anxiety and substance use (DAS) disorder(s) who had not previously received any treatment.
MethodData came from a nationally representative US sample. A total of 34 653 non-institutionalized adults (age ≥20 years) were interviewed at two time points, 3 years apart. DAS disorders, mental health service use and quality of life (QoL) were assessed at both time points.
ResultsIndividuals with a DAS disorder who had not previously received any treatment were significantly more likely than those who had been previously treated to have remission of their index disorder(s) without subsequent treatment, to be free of co-morbid disorder(s) and not to have attempted suicide during the 3-year follow-up period (50.7% v. 33.0% respectively, p < 0.05). At wave 2, multiple linear regression demonstrated that people with a remission of their baseline DAS disorder(s) had levels of functioning similar to those without a DAS disorder.
ConclusionsIndividuals with an untreated DAS disorder at baseline have a substantial likelihood of remission without any subsequent intervention.

Background
Although it has been posited that exposure to adverse childhood experiences (ACEs) increases vulnerability to deployment stress, previous literature in this area has demonstrated conflicting results. Using a cross-sectional population-based sample of active military personnel, the present study examined the relationship between ACEs, deployment related stressors and mood and anxiety disorders.
MethodData were analyzed from the 2002 Canadian Community Health Survey – Canadian Forces Supplement (CCHS-CFS; n = 8340, age 18–54 years, response rate 81%). The following ACEs were self-reported retrospectively: childhood physical abuse, childhood sexual abuse, economic deprivation, exposure to domestic violence, parental divorce/separation, parental substance abuse problems, hospitalization as a child, and apprehension by a child protection service. DSM-IV mood and anxiety disorders [major depressive disorder, post-traumatic stress disorder (PTSD), generalized anxiety disorder (GAD), panic attacks/disorder and social phobia] were assessed using the Composite International Diagnostic Interview (CIDI).
ResultsEven after adjusting for the effects of deployment-related traumatic exposures (DRTEs), exposure to ACEs was significantly associated with past-year mood or anxiety disorder among men [adjusted odds ratio (aOR) 1.34, 99% confidence interval (CI) 1.03–1.73, p < 0.01] and women [aOR 1.37, 99% CI 1.00–1.89, p = 0.01]. Participants exposed to both ACEs and DRTEs had the highest prevalence of past-year mood or anxiety disorder in comparison to those who were exposed to either ACEs alone, DRTEs alone, or no exposure.
ConclusionsACEs are associated with several mood and anxiety disorders among active military personnel. Intervention strategies to prevent mental health problems should consider the utility of targeting soldiers with exposure to ACEs.

The biological mechanisms in the association between maternal body mass index (BMI) and birth weight are not well understood, but are likely to involve maternal plasma glucose levels and nutrient transport across the placenta, both important modulators of fetal growth. Adipose tissue contributes to circulating levels of interleukins that may affect glucose metabolism and possibly also placental transport of nutrients. We investigated possible mediating roles of Interleukin 6 (IL-6) and Interleukin 1 Receptor antagonist (IL-1Ra) in 208 pregnant women. Known and hypothesized dependencies between BMI in early pregnancy and fasting glucose, IL-1Ra and IL-6 at gestational weeks 30–32, and birth weight were specified in a path diagram. Standardized regression coefficients, expressing direct, indirect and total effects, were estimated by Bayesian path analysis. Mean (s.d.) BMI was 24.9 kg/m2 (4.2) and mean (s.d.) birth weight 3748 g (454). The total effect of BMI on birth weight was 0.24 (95% credibility interval (CrI) [0.12, 0.36]). The direct effect of IL-1Ra on birth weight was not statistically significant, but significant effects of BMI on IL-1Ra (0.61, 95% CrI [0.51, 0.72]), of IL-1Ra on fasting glucose (0.17, 95% CrI [0.01, 0.34]) and of fasting glucose on birth weight (0.14, 95% CrI [0.01, 0.27]) implied an indirect pathway from BMI via IL-1Ra on birth weight. Approximately 20% of the effect of BMI on birth weight was mediated through IL-1Ra. For IL-6, no such effects were found. Our results indicate that IL-1Ra may be a mediator in the association between BMI and birth weight.

Laboratory investigations were designed to study the influence of temperature, pH and oxygen tension on the growth of Arthrobotrys oligospora, a nematode-trapping microfungus. Experiments were performed to evaluate the potential role of A. oligospora in destroying third-stage larvae of Cooperia spp. on agar plates and in cattle faeces. The fungus had a growth rate optimum at 23°ree;C and pII 6. Anaerobic cultivation for 23 hours at 23°ree;C and 39°ree;C inhibited fungal growth, but it did not destroy the fungus, which regained growth upon a subsequent shift to aerobic conditions at 23°ree;C. Under experimental conditions in petri-dishes containing agar, the nematode-trapping efficiency of the fungus was striking in that 100% of a population of third-stage larvae of Cooperia spp. was captured within three days of the experiment. The trapping efficiency in faeces was shown to depend upon the inoculation level. At a concentration of approximately 2500 conidia per g faeces, 99% of the larvae were destroyed. The possibilities of using nematode-trapping fungi in controlling animal-parasitic nematodes arc discussed.
The capability of the predacious fungus Arthrobotrys oligospora (Hyphomycetales) to reduce numbers of infective larvae of Ostertagia ostertagi (Trichostrongylidae) in cow pats and herbage during the grazing season in Denmark

Artificially prepared cow pats containing Ostertagia ostertagi eggs were deposited on two pasture plots in May, June and July 1986. Half of the cow pats, placed on one plot, were inoculated with 2000 conidia per gram faeces of the predacious fungus Arthrobotrys oligospora. On the other plot fungus-free control cow pats were placed at the same time. In the faeces generally fewer infective O. ostertagi larvae developed in the inoculated than in the control cow pats. On the herbage around the control cow pats deposited in May, June and July a maxium concentration of infective larvae was found at the same time on the 6th of August 1986. At that time the herbage larval infectivity around inoculated cow pats deposited in May, June and July was subject to a reduction of 48%, 89% and 46%, respectively, compared with fungus-free control cow pats. This experiment indicates that a concentration of 2000 A. oligospora conidia per gram faeces results in a significant lowering of the herbage larval infectivity during the grazing season in Denmark.

Laboratory experiments were designed to select nematophagous fungi that were able to survive in vitro conditions simulating passage through the gastro-intestinal tract of cattle. All of the tests were conducted at 39°C. In a primary stress selection step in diluted rumen fluid, 21 isolates were obtained. Each of the primary stress selected isolates was tested in synthetic saliva, rumen fluid simulating the activity in the rumen, rumen fluid followed by pepsin-hydrochloric acid treatment simulating the additional effect of ruminal and abomasal activity, pepsin-hydrochloric acid solution simulating conditions in the abomasum and finally in a trypsin solution as an example of enzyme activity in the gut. The effect of the rumen fluid alone, or rumen fluid followed by pepsin-hydrochloric acid treatment, were responsible for the reduction in surviving fungal isolates. Only six of thirteen isolates belonging to the genus Arthrobotrys survived while seven of eight isolates of the genus Duddingtonia survived. Fourteen isolates were tested for their predatory capacity in a dung pat bioassay. Fungi of the genera Arthrobotrys and Duddingtonia reduced the development of Ostertagia ostertagi third stage larvae by approximately 75% and 96% respectively compared to the number of larvae that developed from fungus-free control pats.

An attempt was made to control Ostertagia ostertagi by feeding the nematode-trapping fungus Duddingtonia flagrans (DSM 6703) to grazing calves. One group of calves (group E) was fed the fungal material in the first two months of the grazing season while another group was a non-treated control group (group C). Group E showed significantly lower faecal egg count in August and September. On four occasions in July and September, the herbage larval counts were significantly lower on the plot with the fungal-treated group than those recorded on the control plot. The average abomasal larval and adult worm counts were significantly reduced in August in group E and the average total worm count in the abomasum of group E was reduced by 87% in August compared to the non-treated group C. In October, the difference in average abomasal worm counts between group E and C was insignificant. Due to weight loss at the end of the grazing season, the control group showed a significantly lower average weight increase.
