Abstract
Background MRI-guided fusion biopsy is increasingly utilized over systematic 12-core biopsy for men with MRI-visible prostate lesions. Patients and Methods Patients with MRI visible lesions who underwent MRI-guided fusion and systematic 12-core biopsy from 2016-2020 in the Intermountain Healthcare (IHC) system were consecutively analyzed. This was in the setting of a continuous quality assurance initiative among the reading radiologists. Primary outcome was prostate cancer (PCa) detection defined by Gleason grade group (GGG) 1 or higher. Clinically significant cancer (CSC) was defined as GGG 2 or higher. Patients were stratified by biopsy date, 2016-2017 and 2018-2021, and lesions were stratified by PI-RADS v2 category. Results A total of 184 patients with 324 MRI-detectable lesions underwent both biopsy modalities in the IHC system from 2016 to 2021. CSC was detected in 23.5% of MRI-guided fusion biopsies. Comparing PI-RAD v2 categories 1-3 to categories 4-5, rate of CSC was 10% and 42% respectively. MRI-guided fusion and systematic 12-core biopsies were concordant for PCa in 77% of men and CSC in 83%. MRI-guided fusion biopsy detected PCa in 26/103 and CSC in 20/131 men in whom systematic 12-core biopsy was negative. Systematic 12-core biopsy detected PCa in 17/94 and CSC in 11/122 men in whom MRI-guided fusion was negative. Conclusions Omitting MRI-guided fusion or systematic 12-core biopsy would have resulted in underdiagnosis of CSC in 11% or 6% of patients respectively. Combining biopsies increased detection rate of CSC. This was in the setting of a continuous quality assurance program at a large community-based hospital.

Abstract
36 Background: ASCO published a position statement regarding home infusion of anticancer therapy in June 2020. This statement recommends independent research to evaluate the safety and effectiveness of home infusions. Intermountain Healthcare (IM) incorporated this statement into its oncology care with an IRB-approved, prospective single-arm pilot study to determine the safety and feasibility of home administration of checkpoint inhibitor (CPI) immunotherapy with synchronous telemedicine visits. Methods: Patients with cancer receiving treatment at Intermountain Medical Center and Intermountain Cancer Center St. George were screened for enrollment into an IRB-approved, non-randomized pilot study of 20 patients. Eligibility criteria required patients to receive a CPI for an FDA-approved indication, live in Washington County or Salt Lake County, Utah, and have commercial payer coverage of CPI home infusion. Eligible patients were required to receive 2 doses of CPI at an infusion center, and patients who experienced an infusion reaction were excluded from receiving home infusion. Home infusion nurses are trained in oncology, CPIs, and home infusion reaction protocol. During synchronous video visits, infusion nurses are trained to perform the hands-on portions of the physical exam. A financial analysis estimated cost to IM and commercial payers for routine and home CPI infusions. Results: 622 patients were screened, of which 104 were receiving a CPI. 64 patients lived in an eligible county and 19 patients had commercial payer coverage. Of patients on CPIs, 8.7% (9/104) met all eligibility criteria accounting for 1.4% (9/622) of all patients with cancer screened (Table). Financial analysis estimated $829 cost (excluding drug cost) to IM for standard infusion reimbursement compared to $599 for in-home CPI infusions, accounting for savings of $230 per infusion. Majority of cost savings are from elimination of infusion center facilities fee ($495). Analysis includes $269 for home infusion nurse wages. Subsequent analysis for commercial payer SelectHealth estimates $270 reimbursement savings for the payer. Conclusions: Home immunotherapy infusions are estimated to be cost effective for both IM and commercial payers. However, lack of drug coverage and the rural demographics of Utahns with cancer are barriers to home CPI infusions. The pilot study was discontinued per infeasibility stopping criteria.[Table: see text]

Abstract
AbstractObjectiveGender differences in psychosis have been investigated, and the results have contributed to a better understanding of the disease, but many questions are unanswered. In clinical terms, women and men with psychosis differ in terms of access to social support, tendency of substance abuse, level of functioning and symptom patterns. We aimed to investigate how gender differences at onset of psychosis develop during the first 5 years of treatment.MethodA total of 578 patients with a first-episode psychosis in the schizophrenia spectrum were included in the Danish OPUS trial – a randomized clinical trial comparing 2 years of intensive early-intervention programme with standard treatment. All patients were assessed with validated instruments at inclusion, and after 2 and 5 years. Data were analysed for significant gender differences.ResultsMales have significantly higher levels of negative symptoms at all times, and are more likely to live alone and suffer from substance abuse. Females reach higher levels of social functioning at follow-up, and show a greater tendency to be employed or in education than males. Markedly more women than men live with children. More women than men reach a state of recovery and are more compliant with medication.ConclusionThere are significant gender differences at 2- and 5-year follow-up in this large cohort of first-episode psychotic patients. Males and females show different symptomatology and different levels of social functioning.

Abstract
Abstract
Background
QRS morphology including left bundle branch block (LBBB) and duration remain the most widely used surrogate markers in the 12-lead electrocardiogram (ECG) for assessing ventricular dyssynchrony and predicting future burden of heart failure (HF) and cardiovascular mortality. However, the vectorcardiographic QRS area has recently been proposed and evidence suggest that this marker may more accurately predict HF development.
Purpose
The aim of this study was to investigate the association between vectorcardiographic QRS area and risk of HF development in LBBB patients.
Methods
From 2001–2015, the Copenhagen General Practitioners' Laboratory was used to identify patients with a first-time LBBB ECG (QRS>120 ms; LBBB morphology), from which QRS area was derived using the Kors transformation method and grouped into quartiles. Outcome was a composite of HF diagnosis, redeemed prescriptions of loop diuretics, or death from HF. Death from other causes was accounted for as a competing risk.
Results
We included a total of 2843 LBBB patients who were free of heart failure (median age, 70 years; female, 58%; ischemic heart disease, 9%). QRS area quartiles comprised Q1, 67–158 μVs; Q2, 159–189 μVs; Q3, 190–228 μVs; and Q4, 229–739 μVs. During 6-month, 1-year, and 5-year follow-up, 9%, 12%, and 28% of patients reached the combined HF endpoint, and 1%, 2%, and 8% of patients died from other causes, respectively (Figure 1). After multivariable adjustment, the highest QRS area quartile, Q4, was associated with increased HF risk (adjusted hazard ratio, 1.64; 95% confidence interval, 1.35–2.00) compared with the lowest quartile, Q1. We did not observe any significant increase in HF risk for remaining quartiles (Q2 or Q3 vs. Q1).
Figure 1
Conclusions
Among primary care patients with newly discovered LBBB, a large vectorcardiographic QRS area (229–739 μVs) is associated with increased risk of developing the incident, combined HF endpoint. This indicates that the QRS area derived using the Kors method may serve as a valuable prognostic marker when assessing risk of HF in patients with LBBB.

Abstract
OBJECTIVE Involuntary treatment is controversial and widely debated, but remains a significant component of treatment for severe anorexia nervosa. Given how little is known about this topic, we describe the frequency of various involuntary measures in a national cohort of all patients diagnosed with anorexia nervosa. In a subsample of patients, we explored predictors of the first involuntary measure recorded. METHOD Descriptive statistics and Cox proportional hazard analyses were conducted using the national registers of Denmark covering the total population. Data from the National Patient Register and the Psychiatric Central Research Register including all psychiatric visits from 1969 onwards were merged with data from the National Register on Coercion covering 1999 onward. Involuntary measures registered between 2000 and 2013 were analyzed. RESULTS A total of 4,727 patients with a diagnosis of anorexia nervosa representing 16,592 admissions were included. Eighteen percent experienced at least one involuntary measure. A variety of measures were used with tube feeding being the most frequent followed by mechanical restraint, involuntary medication, physical restraint, constant observation, and sedative medication. A subsample of 2% of AN patients had more than 100 involuntary measures recorded. The first recorded involuntary measure was predicted by most but not all psychiatric comorbidities, especially schizophrenia, autism spectrum, and personality disorders, older age at first diagnosis, and previous admissions. DISCUSSION It is important to develop a more granular understanding of patients at risk of requiring involuntary treatment and to determine how best to treat them effectively with minimal use of involuntary measures.

Abstract
BACKGROUND Trauma histories may increase risk of perinatal psychiatric episodes. We designed an epidemiological population-based cohort study to explore if adverse childhood experiences (ACE) in girls increases risk of later postpartum psychiatric episodes. METHODS Using Danish registers, we identified women born in Denmark between January 1980 and December 1998 (129,439 childbirths). Exposure variables were ACE between ages 0 and 15 including: (1) family disruption, (2) parental somatic illness, (3) parental labor market exclusion, (4) parental criminality, (5) parental death, (6) placement in out-of-home care, (7) parental psychopathology excluding substance use, and (8) parental substance use disorder. Primary outcome was first occurrence of in- or outpatient contact 0-6 months postpartum at a psychiatric treatment facility with any psychiatric diagnoses, ICD-10, F00-F99 (N = 651). We conducted survival analyses using Cox proportional hazard regressions of postpartum psychiatric episodes. RESULTS Approximately 52% of the sample experienced ACE, significantly increasing risk of any postpartum psychiatric diagnosis. Highest risks were observed among women who experienced out-of-home placement, hazard ratio (HR) 2.57 (95% CI: 1.90-3.48). Women experiencing two adverse life events had higher risks of postpartum psychiatric diagnosis HR: 1.88 (95% CI: 1.51-2.36), compared to those with one ACE, HR: 1.24 (95% CI: 1.03-49) and no ACE, HR: 1.00 (reference group). CONCLUSIONS ACE primarily due to parental psychopathology and disability contributes to increased risk of postpartum psychiatric episodes; and greater numbers of ACE increases risk for postpartum psychiatric illness with an observed dose-response effect. Future work should explore genetic and environmental factors that increase risk and/or confer resilience.

Abstract
BackgroundPatients with first-episode psychosis comprise a high-risk group in terms of suicide.AimsTo identify predictive factors for suicidal behaviour and to examine the effect of integrated treatment on suicidal behaviour and hopelessness.MethodA total of 341 patients with a first-episode schizophrenia-spectrum disorder were randomised to integrated treatment or treatment as usual.ResultsDuring the 1-year follow-up period, 11% attempted suicide. This was associated with female gender, hopelessness, hallucinations and suicide attempt reported at baseline, with the two latter variables being the only significant ones in the final multivariate model. The integrated treatment reduced hopelessness.ConclusionsHallucinations and suicide attempt before inclusion in the study were the most significant predictors of suicide attempt in the follow-up period.

Abstract
OBJECTIVE Mesolimbic dopamine sensitization has been hypothesized to be a mediating factor of childhood adversity (CA) on schizophrenia risk. Activity of catechol-O-methyltransferase (COMT) Val158Met increases mesolimbic dopamine signaling and may be further regulated by methylenetetrahydrofolate reductase (MTHFR) C677T. This study investigates the three-way interaction between CA, COMT, and MTHFR. METHODS We conducted a nested case-control study on individuals born after 1981, linking population-based registers to study the three-way interaction. We included 1699 schizophrenia cases and 1681 controls, and used conditional logistic regression to report incidence rate ratios (IRRs). RESULTS Childhood adversity was robustly associated with schizophrenia. No main genetic effects were observed. MTHFR C677T increased schizophrenia risk in a dose-dependent manner per MTHFR T allele (P = 0.005) consequent upon CA exposure. After inclusion of the significant (P = 0.03) COMT × MTHFR × CA interaction, the risk was further increased per high-activity COMT Val allele. Hence, exposed COMT Val/Val and MTHFR T/T carriers had an IRR of 2.76 (95% CI, 1.66-4.61). Additional adjustments for ancestry and parental history of mental illness attenuated the results with the interaction being only marginally significant. CONCLUSION MTHFR C677T and COMT Val158Met interact with CA to increase risk of schizophrenia.

Abstract
IntroductionPrior studies have indicated that both high and low school achievement are associated with development of bipolar disorder (BD). We believe that the latter association may be due to the confounding effect of family history of mental disorder.ObjectiveTo further investigate the association between school achievement and subsequent development of BD by adding adjustment for family history of mental disorder.MethodsWe are conducting a historical prospective cohort study based on data from nationwide Danish registers. The cohort consists of all individuals born in Denmark 1986–97 of Danish-born parents, who were alive and living in Denmark at age 16 years, and who have completed final examinations in 9th grade between 2002 and 2014 (n = 578,247). The cohort members will be followed until death, emigration, development of bipolar disorder, or end of study, whichever comes first. Hazard rate ratios for bipolar disorder will be calculated in a Cox model using the z-score for examination grades as unit of exposure. The regression analyses will be adjusted for a series of potential confounders including family history of mental disorder.ResultsWe expect to find a positive association between high school achievement and development of BD. In contrast, we expect to demonstrate that the association between low school achievement and BD detected in prior studies is due to confounding by family history of mental disorder. The results will be shown at the conference.ConclusionsBy further testing the potential link between eminence and BD, we hope to contribute to a more balanced perception of BD.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
OBJECTIVE Severe infections are associated with increased risks of mental disorders; however, this is the first large-scale study investigating whether infections treated with anti-infective agents in the primary care setting increase the risks of schizophrenia and affective disorders. METHOD We identified all individuals born in Denmark 1985-2002 (N = 1 015 447) and studied the association between infections treated with anti-infective agents and the subsequent risk of schizophrenia and affective disorders during 1995-2013. Cox regression analyses were adjusted for important confounders. RESULTS Infections treated with anti-infective agents were associated with increased risks of schizophrenia by a hazard rate ratio (HRR) of 1.37 (95%-CI = 1.20-1.57) and affective disorders by a HRR of 1.64 (95%-CI = 1.48-1.82), fitting a dose-response and temporal relationship (P < 0.001). The excess risk was primarily driven by infections treated with antibiotics, whereas infections treated with antivirals, antimycotics, and antiparasitic agents were not significant after mutual adjustment. Individuals with infections requiring hospitalization had the highest risks for schizophrenia (HRR = 2.05; 95%-CI = 1.77-2.38) and affective disorders (HRR = 2.59; 95%-CI = 2.31-2.89). CONCLUSION Infections treated with anti-infective agents and particularly infections requiring hospitalizations were associated with increased risks of schizophrenia and affective disorders, which may be mediated by effects of infections/inflammation on the brain, alterations of the microbiome, genetics, or other environmental factors.

Abstract
The olfactory receptor (OR) family was found to be expressed mainly in the nasal epithelium. In the last two decades members of the OR family were detected to be functional expressed in different parts of the human body such as in liver, prostate or intestine cancer cells. Here, we detected the expression of several ORs in the human chronic myelogenous leukemia (CML) cell line K562 and in white blood cells of clinically diagnosed acute myeloid leukemia (AML) patients by RT-PCR and next-generation sequencing. With calcium-imaging, we characterized in greater detail the cell biological role of one OR (OR2AT4) in leukemia. In both cell systems, the OR2AT4 agonist Sandalore-evoked strong Ca2+ influx via the adenylate cyclase-cAMP-mediated pathway. The OR2AT4 antagonist Phenirat prevented the Sandalore-induced intracellular Ca2+ increase. Western blot and flow cytometric experiments revealed that stimulation of OR2AT4 reduced the proliferation by decreasing p38-MAPK phosphorylation and induced apoptosis via phosphorylation of p44/42-MAPK. Furthermore, Sandalore increased the number of hemoglobin-containing cells in culture. We described for the first time an OR-mediated pathway in CML and AML that can regulate proliferation, apoptosis and differentiation after activation. This mechanism offers novel therapeutic options for the treatment of AML.

Abstract
Adipose-derived stromal cells (ASCs) are mostly isolated by enzymatic digestion, centrifugation and adherent growth resulting in a very heterogeneous cell population. Therefore, other cell types in the cell culture can comprise the differentiation and proliferation potential of the ASC population. Recent studies indicated that an antibody-aided isolation of distinct ASC subpopulations provides advantages over the conventional method of ASC isolation. The aim of this study was to investigate the adipogenic differentiation potential of CD29-, CD71-, CD73- and CD90-selected ASCs in vitro. The stromal vascular fraction (SVF) was obtained from rat adipose tissue by enzymatic digestion and centrifugation. Subsequently, CD29(+)-, CD71(+)-, CD73(+)- and CD90(+) cells were isolated by magnetic activated cell sorting (MACS), seeded into culture plates and differentiated into the adipogenic lineage. ASCs isolated by adherent growth only served as controls. Adipogenic differentiation was assessed by Oil Red O staining and quantification of the adiponectin and leptin concentrations in the cell culture supernatants. Statistical analysis was carried out using one-way analysis of variance (ANOVA) followed by the Scheffe's post hoc procedure. The results showed that different subpopulations with different adipogenic differentiation potentials can be isolated by the MACS procedure. The highest adipogenic differentiation potential was determined in the CD29-selected ASC population followed by the unsorted ASC population. The CD71-, CD73- and CD90-selected cells exhibited significantly the lowest adipogenic differentiation potential. In conclusion, the CD29-selected ASCs and the unsorted ASCs exhibited a similar adipogenic differentiation potential. Therefore, we do not see a clear advantage in the application of an anti-CD29-based isolation of ASCs over the conventional technique using adherent growth. However, the research on isolation/purification methods of adipogenic ASCs should continue in order to make this stem cell source even more attractive for future adipose tissue engineering applications.

Abstract
BACKGROUND Several studies indicate that cannabis use among patients with psychotic disorders is associated with worse outcome, but only a few studies have controlled for baseline condition and medication. METHOD At 5-year follow-up, interviews were carried out with 314 first-episode psychosis patients included in the OPUS trial. The patients included were in the age range of 18 to 45 years old and 59% were male. Cannabis use was extracted from the Schedule for Clinical Assessment in Neuropsychiatry. At follow-up, the patients were divided into different groups according to the variable cannabis use: abstainers, stoppers, starters and continuers. Psychotic, negative and disorganized dimensions (ranging from zero to five) were calculated for each of the four groups based on the Schedule for the Assessment of Positive and Negative Symptoms in Schizophrenia. RESULTS Cannabis users were younger (24.6 years v. 27.4 years, p < 0.001) and had a lower level of education. At the 5-year follow-up, users of cannabis had higher scores on the psychotic dimension [difference 0.97, 95% confidence interval (CI) 0.41-1.53, p = 0.001] and lower levels of the Global Assessment of Functioning (difference 8.26, 95% CI 2.13-14.39, p = 0.01). Those who stopped using cannabis between entry and 5-year follow-up had a significantly lower level of psychotic symptoms at 5-year follow-up even after controlling for baseline level of psychotic symptoms and for insufficient antipsychotic medication (adjusted difference in psychotic dimension -1.04, 95% CI -1.77 to -0.31, p = 0.006). CONCLUSIONS Continuous cannabis use was associated with higher levels of psychotic symptoms after 5 years, and this association was only partly explained by insufficient antipsychotic medication.

Abstract
BACKGROUND The effects of hospital-based rehabilitation including weekly supportive psychodynamic therapy compared with specialized assertive intervention and standard treatment has not previously been investigated in first-episode psychosis. The aim of the study was to examine long-term effect on use of institutional care of different intensive interventions for patients with first-episode schizophrenia spectrum disorder on use of psychiatric bed days and days in supported housing. METHOD A total of 94 severely ill patients with first-episode schizophrenia spectrum disorders were included in a special part of the Copenhagen OPUS trial and randomized to either the specialized assertive intervention program (OPUS), standard treatment or hospital-based rehabilitation. RESULTS It was a stable pattern that patients randomized to hospital-based rehabilitation spent more days in psychiatric wards and in supported housing throughout the 5-year follow-up period compared with the two other groups. Patients in OPUS treatment spent significantly fewer days in psychiatric wards and supported housing in the first 3 years compared with patients in hospital-based rehabilitation. Due to attrition and small sample size, differences in level of psychotic and negative symptoms at 5-year follow-up could not be evaluated. CONCLUSIONS The study indicates that hospital-based rehabilitation together with weekly supportive psychodynamic therapy was associated with a continued increased use of psychiatric bed days and days in supported housing. The data cannot justify using hospital-based rehabilitation in first-episode psychosis.

Abstract
OBJECTIVES This study was performed to explore the strategy of combining Chk1 inhibitors with ionizing radiation (IR) to selectively target p53-deficient cancer cells. MATERIALS AND METHODS Survival and cell cycle progression were measured in response to IR and the Chk1 inhibitors, UCN-01 and CEP-3891, in colon carcinoma HCT116 p53+/+ and p53-/- cells, and in osteosarcoma U2OS-VP16 cells with conditional expression of dominant-negative p53 (p53DD). RESULTS Clonogenic survival was selectively reduced in HCT116 p53-/- compared to p53+/+ cells after treatment with UCN-01 and IR, and HCT116 p53+/+ cells also displayed strong p53-dependent G(1) arrest in the 1st cell cycle after IR. In contrast, clonogenic survival was affected similarly in U2OS-VP16 cells with and without expression of p53DD. However, death of U2OS-VP16 cells was p53 dependent as assessed by cell viability assay at 72 h, and this was associated with p53-dependent G(1) arrest in the 2nd cell cycle after treatment. Notably, HCT116 cells were overall more resistant than U2OS cells to cytotoxic effects of Chk1 inhibitors. CONCLUSION Our results suggest that p53-dependent G(1) arrest in both 1st and 2nd cell cycles may protect human cancer cells from cell death after treatment with IR and Chk1 inhibitors. However, a challenge for future clinical use will be that different cancers display different intrinsic sensitivity to such inhibitors.
