Monte Carlo Simulations Demonstrate Algorithmic Interventions Over Time Reduce Hospitalisation in Patients With Schizophrenia and Bipolar Disorder

Non-adherence with pharmacologic treatment is associated with increased rates of relapse and rehospitalisation among patients with schizophrenia and bipolar disorder. To improve treatment response, remission, and recovery, research efforts are still needed to elucidate how to effectively map patient’s response to medication treatment including both therapeutic and adverse effects, compliance, and satisfaction in the prodromal phase of illness (ie, the time period in between direct clinical consultation and relapse). The Actionable Intime Insights (AI 2 ) application draws information from Australian Medicare administrative claims records in real time when compliance with treatment does not meet best practice guidelines for managing chronic severe mental illness. Subsequently, the AI 2 application alerts clinicians and patients when patients do not adhere to guidelines for treatment. The aim of this study was to evaluate the impact of the AI 2 application on the risk of hospitalisation among simulated patients with schizophrenia and bipolar disorder. Monte Carlo simulation methodology was used to estimate the impact of the AI 2 intervention on the probability of hospitalisation over a 2-year period. Results indicated that when the AI 2 algorithmic intervention had an efficacy level of (>0.6), over 80% of actioned alerts were contributing to reduced hospitalisation risk among the simulated patients. Such findings indicate the potential utility of the AI 2 application should replication studies validate its methodologic and ecological rigour in real-world settings

Characteristics of patients seen by visiting psychiatrists through Medicare in a rural community mental health service with an established telemedicine service

Objective: We aimed to determine characteristics of patients receiving Medicare-funded face-to-face consultations by psychiatrists in a rural service with an established telemedicine service. Methods: For this study, 55 case-managed patients from four rural community mental health teams in South Australia provided information through questionnaires regarding psychological symptoms, quality of life, body mass index (BMI) and gave access to their Medicare data. Results: In a logistic regression, it was found that being younger was more likely associated with a Medicare psychiatric consultation (p<0.05). Participants with at least one recorded visit to a Medicare psychiatrist consultation also tended to have lower levels of psychological distress at the end of the 4-year period, have a higher BMI, and more general practitioner consultations. Conclusion: The study provides clinicians and policy makers with preliminary information on the subtle differences in clinical profile of patients seen by Medicare-funded psychiatrists within an established state-managed telepsychiatry service

Aurora Kinase Inhibitor PHA-739358 Suppresses Growth of Hepatocellular Carcinoma In Vitro and in a Xenograft Mouse Model1

Patients with advanced stages of hepatocellular carcinoma (HCC) face a poor prognosis. Although encouraging clinical results have been obtained with multikinase inhibitor sorafenib, the development of improved therapeutic strategies for HCC remains an urgent goal. Aurora kinases are key regulators of the cell cycle, and their uncontrolled expression promotes aneuploidy and tumor development. In tissue microarray analyses, we detected aurora-A kinase expression in all of the examined 93 human HCC samples, whereas aurora-B kinase expression levels significantly correlated with the proliferation index of HCCs. In addition, two human HCC cell lines (Huh-7 and HepG2) were tested positive for aurora-A and -B and revealed Ser10 phosphorylation of histone H3, indicating an increased aurora-B kinase activity. The antiproliferative features of a novel aurora kinase inhibitor, PHA-739358, currently under investigation in phase 2 clinical trials for other solid tumors, were examined in vitro and in vivo. At concentrations exceeding 50nM, PHA-739358 completely suppressed tumor cell proliferation in cell culture experiments and strongly decreased histone H3 phosphorylation. Cell cycle inhibition and endoreduplication were observed at 50 nM, whereas higher concentrations led to a complete G2/M-phase arrest. In vivo, administration of PHA-739358 resulted in significant tumor growth inhibition at a well-tolerated dose. In combination with sorafenib, additive effects were observed. Remarkably, when tumors restarted to grow under sorafenib monotherapy, subsequent treatment with PHA-739358 induced tumor shrinkage by up to 81%. Thus, targeting aurora kinases with PHA-739358 is a promising therapeutic strategy administered alone or in combination with sorafenib for patients with advanced stages of HCC

Management of Germ Cell Tumours of the Testis in Adult Patients. German Clinical Practice Guideline Part I: Epidemiology, Classification, Diagnosis, Prognosis, Fertility Preservation, and Treatment Recommendations for Localized Stages

Introduction: This is the first German evidence- and consensus-based clinical guideline on diagnosis, treatment, and follow-up on germ cell tumours (GCTs) of the testis in adult patients. We present the guideline content in two publications. Part I covers the topic's background, methods, epidemiology, classification systems, diagnostics, prognosis, and treatment recommendations for the localized stages. Methods: An interdisciplinary panel of 42 experts including 1 patient representative developed the guideline content. Clinical recommendations and statements were based on scientific evidence and expert consensus. For this purpose, evidence tables for several review questions, which were based on systematic literature searches (last search was in March 2018) were provided. Thirty-one experts entitled to vote, rated the final clinical recommendations and statements. Results: We provide 161 clinical recommendations and statements. We present information on the quality of cancer care and epidemiology and give recommendations for staging and classification as well as for diagnostic procedures. The diagnostic recommendations encompass measures for assessing the primary tumour as well as procedures for the detection of metastases. One chapter addresses prognostic factors. In part I, we separately present the treatment recommendations for germ cell neoplasia in situ, and the organ-confined stages (clinical stage I) of both seminoma and nonseminoma. Conclusion: Although GCT is a rare tumour entity with excellent survival rates for the localized stages, its management requires an interdisciplinary approach, including several clinical experts. Quality of care is highly related to institutional expertise and can be reassured by established online-based second-opinion boards. There are very few studies on diagnostics with good level of evidence. Treatment of metastatic GCTs must be tailored to the risk according to the International Germ Cell Cancer Collaboration Group classification after careful diagnostic evaluation. An interdisciplinary approach as well as the referral of selected patients to centres with proven experience can help achieve favourable clinical outcomes

Functional Outcome of Intravenous Thrombolysis in Patients With Lacunar Infarcts in the WAKE-UP Trial

Importance: The rationale for intravenous thrombolysis in patients with lacunar infarcts is debated, since it is hypothesized that the microvascular occlusion underlying lacunar infarcts might not be susceptible to pharmacological reperfusion treatment. Objective: To study the efficacy and safety of intravenous thrombolysis among patients with lacunar infarcts. Design, Setting, and Participants: This exploratory secondary post hoc analysis of the WAKE-UP trial included patients who were screened and enrolled between September 2012 and June 2017 (with final follow-up in September 2017). The WAKE-UP trial was a multicenter, double-blind, placebo-controlled randomized clinical trial to study the efficacy and safety of intravenous thrombolysis with alteplase in patients with an acute stroke of unknown onset time, guided by magnetic resonance imaging. All 503 patients randomized in the WAKE-UP trial were reviewed for lacunar infarcts. Diagnosis of lacunar infarcts was based on magnetic resonance imaging and made by consensus of 2 independent investigators blinded to clinical information. Main Outcomes and Measures: The primary efficacy variable was favorable outcome defined by a score of 0 to 1 on the modified Rankin Scale at 90 days after stroke, adjusted for age and severity of symptoms. Results: Of the 503 patients randomized in the WAKE-UP trial, 108 patients (including 74 men [68.5%]) had imaging-defined lacunar infarcts, whereas 395 patients (including 251 men [63.5%]) had nonlacunar infarcts. Patients with lacunar infarcts were younger than patients with nonlacunar infarcts (mean age [SD], 63 [12] years vs 66 [12] years; P = .003). Of patients with lacunar infarcts, 55 (50.9%) were assigned to treatment with alteplase and 53 (49.1%) to receive placebo. Treatment with alteplase was associated with higher odds of favorable outcome, with no heterogeneity of treatment outcome between lacunar and nonlacunar stroke subtypes. In patients with lacunar strokes, a favorable outcome was observed in 31 of 53 patients (59%) in the alteplase group compared with 24 of 52 patients (46%) in the placebo group (adjusted odds ratio [aOR], 1.67 [95% CI, 0.77-3.64]). There was 1 death and 1 symptomatic intracranial hemorrhage according to Safe Implementation of Thrombolysis in Stroke-Monitoring Study criteria in the alteplase group, while no death and no symptomatic intracranial hemorrhage occurred in the placebo group. The distribution of the modified Rankin Scale scores 90 days after stroke also showed a nonsignificant shift toward better outcomes in patients with lacunar infarcts treated with alteplase, with an adjusted common odds ratio of 1.94 (95% CI, 0.95-3.93). Conclusions and Relevance: While the WAKE-UP trial was not powered to demonstrate the efficacy of treatment in subgroups of patients, the results indicate that the association of intravenous alteplase with functional outcome does not differ in patients with imaging-defined lacunar infarcts compared with those experiencing other stroke subtypes.status: publishe
