Introduction: Epidemiologic and modeling studies suggest that between 45 and 70% of individuals with chronic hepatitis C virus (HCV) infection in Canada remain undiagnosed. The Canadian Association for the Study of the Liver (CASL) recommends one-time screening of baby boomers (1945-1975). Screening programs in the US have shown a very high prevalence of previously undiagnosed HCV among patients seen in the emergency department (ED). We sought to assess the feasibility of implementing a targeted birth-cohort HCV screening program in a Canadian ED setting. Methods: Patients born from 1945 to 1975 presenting to the ED of a downtown Toronto hospital were offered HCV testing. Patients with life-threatening conditions, unable to provide verbal consent in English or intoxication were excluded. Blood samples were collected by finger prick on Dried Blood Spot (DBS) collection cards and tested for anti-HCV antibody with reflex to HCV RNA. Patients with positive HCV RNA were referred to a liver specialist. Results: During a 27-month period (July 2017 - Sept 2019), 8363 patients in the birth cohort presented to the ED during daytime hours. 80% (6714) met eligibility criteria, and 48.4% (3247) were offered testing. Screening was performed by non-medical staff (mean 8/day, median spots on DBS 4). 345 (10.6%) had been previously tested, and 639 (19.7%) declined. 2136 (65.8%) patients underwent testing: median age 58.4 years (40-82), 1117 male (52.3%). Of these, 45 patients (2.1%; 95% CI 1.5%-2.7%) were anti-HCV positive: 32 (76.2%) were HCV RNA positive, 10 (23.8%) negative and 3 not done due to inadequate DBS sample. 26 patients (81.3%) were linked to care and 3 (9.4%) lost to follow-up. HCV prevalence in the ED was significantly higher than the general Canadian population (2.1% vs 0.7%; p < 0.0001) but much lower than reported rates in American EDs (2.1% vs 10.3%; p < 0.0001). Conclusion: Acceptance of HCV screening in the ED birth cohort was high and easily performed using DBS to ensure the majority of positive samples were tested for HCV RNA. Challenges included implementation that limited number of people tested, and linkage to care for HCV positive patients. HCV prevalence among this ED birth cohort was higher than the general population but lower than seen in the ED in the US. This may in part be due to exclusion of individuals with more severe medical issues, refusal by higher risk subgroups, or population and healthcare system differences between countries.
Attempts to reduce high utilisation of psychiatric inpatient care by targeting the critical time of hospital discharge have been rare. In Germany, until now no such intervention has been implemented, let alone subjected to a clinical trial.
“Effectiveness and Cost-Effectiveness of Needs-Oriented Discharge Planning and Monitoring for High Utilisers of Psychiatric Services” (NODPAM) is a multicentre RCT conducted in five psychiatric hospitals in Germany (Günzburg, Düsseldorf, Regensburg, Greifswald, and Ravensburg). Subjects asked to provide informed consent to participate have to be of adult age with a primary diagnosis of schizophrenia or affective disorder, and a defined high utilisation of psychiatric care during two years prior to the current admission. Subjects are asked to provide detailed outcome data at four measurement points during a period of 18 months. Recruitment (which started in April 06) is still ongoing. Thus, baseline data of about 350 participants will be presented.
Recruitment has been quite successful and the study has been generally well accepted by participating patients and their clinicians in in- and outpatient treatment settings. Subjects showed substantial initial impairment on outcome measures (e.g. needs, psychopathology, quality of life, and level of functioning) and high utilisation of mental health care. Further results on conduct and feasibility of the trial will be presented.
The first phase of this mulicentre trial was promising. The potential of this study to strengthen the integration of mental health care provision in Germany will be discussed.
Aim of this contribution is to describe the intervention used in the study “Effectiveness and Cost-Effectiveness of Needs-Oriented Discharge Planning and Monitoring for High Utilisers of Psychiatric Services” (NODPAM). This intervention applies principles of needs-led care and focusses on the inpatient-outpatient transition. The NODPAM intervention manual includes a range of predefined standardised options based on number and type of needs.
For the intervention group, a trained intervention worker provides a coherent package of needs-oriented discharge planning and monitoring focussing on the care process. He or she emphasises continuity of the care process vis-à-vis both patient and clinician (and carers if possible) via providing two manualised intervention sessions): (a) A discharge planning session takes place just before discharge with the patient and responsible clinician at the inpatient service; (b) A monitoring session takes place three months after discharge with the patient and outpatient clinician (office-based or public outpatient mental health service-based). A written treatment plan is signed by and forwarded to all participants after each session.
Acceptance of the intervention by patients and clinicians has been high so far. Further results on duration, participant characteristics, and participants' appraisal of the NODPAM intervention will be presented.
These first results indicate that the NODPAM intervention is feasible in inpatient mental health services in Germany. Discussion will focus on its applicability in other service systems.
Early-onset first-episode psychosis (FEP) and high functioning autism spectrum disorders (ASD) are complex neuro–developmental disorders that share symptomatology but it is not clear if they also share neurobiological abnormalities (Chisholm et al., 2015). We examined thickness, surface area and volume in a direct comparison of children and adolescents with FEP (onset before 18 years), high-functioning ASD, and healthy subjects.
Magnetic resonance imaging scans of 85 participants (30 ASD, 29 FEP, 26 healthy controls, age range 10–18 years) were obtained from the same MR scanner using the same acquisition protocol. The FreeSurfer analysis suite was used to quantify vertex-wise estimates of the metrics thickness, surface area, and volume.
ASD and FEP had spatially overlapping insular deficits for each metric. The transdiagnostic overlap of deficits was greatest for volume (55% of all insular vertices) and smallest for thickness (18%). Insular thickness and surface area deficits did not overlap in ASD and overlapped only in 8% of all insular vertices in FEP.
Morphological insular deficits are common to FEP and high functioning ASD when compared to healthy participants. The pattern of deficits was similar in both disorders, i.e. a largely non-overlap of insular thickness and surface area. The non-overlap provides further evidence that these metrics represent two independent outcomes of corticogenesis, both of which are affected in FEP and ASD.

Eight ruminally-fistulated wethers were used to examine the temporal effects of afternoon (PM; 1600h) v. morning (AM; 0800 h) allocation of fresh spring herbage from a perennial ryegrass (Lolium perenne L.)-based pasture on fermentation and microbial community dynamics. Herbage chemical composition was minimally affected by time of allocation, but daily mean ammonia concentrations were greater for the PM group. The 24-h pattern of ruminal fermentation (i.e. time of sampling relative to time of allocation), however, varied considerably for all fermentation variables (P⩽0.001). Most notably amongst ruminal fermentation characteristics, ammonia concentrations showed a substantial temporal variation; concentrations of ammonia were 1.7-, 2.0- and 2.2-fold greater in rumens of PM wethers at 4, 6 and 8h after allocation, respectively, compared with AM wethers. The relative abundances of archaeal and ciliate protozoal taxa were similar across allocation groups. In contrast, the relative abundances of members of the rumen bacterial community, like Prevotella 1 (P=0.04), Bacteroidales RF16 group (P=0.005) and Fibrobacter spp. (P=0.008) were greater for the AM group, whereas the relative abundance of Kandleria spp. was greater (P=0.04) for the PM group. Of these taxa, only Prevotella 1 (P=0.04) and Kandleria (P<0.001) showed a significant interaction between time of allocation and time of sampling relative to feed allocation. Relative abundances of Prevotella 1 were greater at 2h (P=0.05), 4h (P=0.003) and 6h (P=0.01) after AM allocation of new herbage, whereas relative abundances of Kandleria were greater at 2h (P=0.003) and 4h (P<0.001) after PM allocation. The early post-allocation rise in ammonia concentrations in PM rumens occurred simultaneously with sharp increases in the relative abundance of Kandleria spp. and with a decline in the relative abundance of Prevotella. All measures of fermentation and most microbial community composition data showed highly dynamic changes in concentrations and genus abundances, respectively, with substantial temporal changes occurring within the first 8h of allocating a new strip of herbage. The dynamic changes in the relative abundances of certain bacterial groups, in synchrony with a substantial diurnal variation in ammonia concentrations, has potential effects on the efficiency by which N is utilised by the grazing ruminant.
