CD91-mediated reprogramming of DCs by immunogenic heat shock proteins requires the kinases AXL and Fgr.

Immune responses to tumors, comprising adaptive T cells and innate NK cells, arise very early in tumorigeneses and prior to detection of palpable tumors or before tissue pathology is evident. Yet, how nascent tumors evoke dendritic cell maturation and the resulting cytokine responses that are necessary for these effector anti-tumor immune responses is unknown. We have previously shown that CD91 expression on dendritic cells is important for immune surveillance, specifically for generating T cell and NK cell responses to nascent tumors.

Left Atrial Appendage Closure in Atrial Fibrillation Patients with Cancer.

: There are limited data about left atrial appendage closure (LAAC) in patients with cancer. We therefore sought to compare the outcome after LAAC in patients with vs. without cancer in a multicentre registry.

Renal sympathetic denervation 2024 in Austria: recommendations from the Austrian Society of Hypertension : Endorsed by the Austrian Society of Nephrology and the Working Group of Interventional Cardiology of the Austrian Society of Cardiology.

Renal sympathetic denervation (RDN) is an interventional supplement to medical treatment in patients with arterial hypertension. While the first sham-controlled trial, SYMPLICITY HTN‑3 was neutral, with improved procedural details, patient selection and follow-up, recent randomized sham-controlled trials of second-generation devices show a consistent blood pressure lowering effect of RDN, as compared to sham controls. These new data and the recent U.

CD91 and Its Ligand gp96 Confer Cross-Priming Capabilities to Multiple APCs during Immune Responses to Nascent, Emerging Tumors.

During cancer immunosurveillance, dendritic cells (DC) play a central role in orchestrating T-cell responses against emerging tumors. Capture of miniscule amounts of antigen along with tumor-initiated costimulatory signals can drive maturation of DCs. Expression of CD91 on DCs is essential in cross-priming of T-cell responses in the context of nascent tumors.

Legal Implications of Psychiatric Assessment for Medical Aid in Dying.

In recent years, several jurisdictions have passed legislation to permit medical aid in dying (MAID) worldwide, with considerable expansion in the availability of this practice. MAID has been defined as the practice of a clinician prescribing lethal drugs in response to a direct request from the patient, with a shared understanding that the patient intends to use the medication to bring about the patient's death. Wider legalization of MAID has prompted debates and legal controversies regarding the extent to which MAID should be available and its application for people experiencing mental illness as the primary indication.

Attitudes of Forensic Fellowship Psychiatry Directors towards an Applicant Match.

Forensic psychiatry fellowship programs recruit applicants through a nonstandardized process that differs by program. Although there are deadlines, informal guidance, and more recent communication guidelines, perceived differences in recruitment practices persist between geographic regions, small and large programs, and newer and more well-established programs. In the wake of a survey of fellowship applicants that found mixed opinions surrounding the application process, U.

Long-term outcomes after echocardiography versus fluoroscopy-guided left atrial appendage closure: Is there still a role for a simplified approach?

Background: Left atrial appendage closure (LAAC) represents an alternative to oral anticoagulation for stroke prevention in patients with non-valvular atrial fibrillation (AF). While transoesophageal echocardiography is the current standard for guiding LAAC procedures, several centers have employed fluoroscopic guidance alone. However, data on long-term outcomes are lacking.

Minding the margins: Evaluating the impact of COVID-19 among Latinx and Black communities with optimal qualitative serological assessment tools.

COVID-19 disproportionately affected minorities, while research barriers to engage underserved communities persist. Serological studies reveal infection and vaccination histories within these communities, however lack of consensus on downstream evaluation methods impede meta-analyses and dampen the broader public health impact. To reveal the impact of COVID-19 and vaccine uptake among diverse communities and to develop rigorous serological downstream evaluation methods, we engaged racial and ethnic minorities in Massachusetts in a cross-sectional study (April - July 2022), screened blood and saliva for SARS-CoV-2 and human endemic coronavirus (hCoV) antibodies by bead-based multiplex assay and point-of-care (POC) test and developed across-plate normalization and classification boundary methods for optimal qualitative serological assessments.

The Evolving Standard of Care for Autoimmune Neuropsychiatric Illness.

In recent decades, there has been increasing biomedical and public understanding of the role of autoimmunity in neuropsychiatric illness. Popular media have highlighted patients with psychiatric illnesses who were eventually diagnosed with autoimmune neuropsychiatric illnesses such as anti N-methyl-D-aspartate receptor encephalitis. Coverage of these cases has often drawn attention to the effects of misdiagnosis or delayed diagnosis of such diseases in psychiatric patients.

Same-day discharge after percutaneous coronary procedures-Consensus statement of the working group of interventional cardiology (AGIK) of the Austrian Society of Cardiology.

Introduction: Percutaneous coronary intervention is a well-established revascularization strategy for patients with coronary artery disease. Recent technical advances such as radial access, third generation drug-eluting stents and highly effective antiplatelet therapy have substantially improved the safety profile of coronary procedures. Despite several practice guidelines and a clear patient preference of early hospital discharge, the percentage of coronary procedures performed in an outpatient setting in Austria remains low, mostly due to safety concerns.

Same-day discharge after percutaneous coronary procedures-Structured review and comprehensive meta-analysis.

Introduction: Percutaneous coronary intervention is a well-established revascularization strategy for patients with coronary artery disease. The safety and feasibility of performing these procedures on a same-day discharge basis for selected patients has been studied in a large number of mostly nonrandomized trials. An up to date literature review should focus on trials with radial access, representing the current standard for coronary procedures in Austria and other European countries.

Discovery of -Linked Nucleoside Analogues with Antiviral Activity against SARS-CoV-2.

The recent COVID-19 pandemic underscored the limitations of currently available direct-acting antiviral treatments against acute respiratory RNA-viral infections and stimulated major research initiatives targeting anticoronavirus agents. Two novel nsp5 protease (MPro) inhibitors have been approved, nirmatrelvir and ensitrelvir, along with two existing nucleos(t)ide analogues repurposed as nsp12 polymerase inhibitors, remdesivir and molnupiravir, but a need still exists for therapies with improved potency and systemic exposure with oral dosing, better metabolic stability, and reduced resistance and toxicity risks. Herein, we summarize our research toward identifying nsp12 inhibitors that led to nucleoside analogues and , which showed favorable pan-coronavirus activity in cell-infection screens, were metabolized to active triphosphate nucleotides in cell-incubation studies, and demonstrated target (nsp12) engagement in biochemical assays.

The Forensic Mental Health Implications of Social Media Challenges.

Children and adults are increasingly spending time on social networking sites where they may be exposed to social media challenges. These challenges, which are essentially dares or competitions, often involve participants recording themselves performing various activities to create a short video which they then share online. Many social media challenges may be considered relatively benign, but others may involve behaviors or tasks that lead to adverse outcomes, including injury and death.

Extensive thoracoabdominal aortic electro septotomy: A case report of a novel approach in the treatment of chronic aortic dissections.

Treatment of post-dissection arch and thoracoabdominal aortic aneurysms presents significant therapeutic challenges. True lumen collapse or take off of aortic branches from the false lumen makes endograft alignment difficult, if not impossible. We present herein the first successful case of an extensive thoracoabdominal electro aortic septotomy of the entire dissection membrane from the aortic arch down to the aortic bifurcation during an open redo aortic arch replacement employing the frozen elephant trunk technique.

Cardiovascular Rehabilitation With a WCD-Data From the CR3 Study (Cardiac Rehab Retrospective Review).

Purpose: Patients at risk for sudden cardiac death may temporarily need a wearable cardioverter-defibrillator (WCD). Exercise-based cardiac rehabilitation (CR) has a class I recommendation in patients with cardiac disease. The aim of this study was to evaluate the safety and feasibility of undergoing CR with a WCD.

Clinical Utility of SARS-CoV-2 Serological Testing and Defining a Correlate of Protection.

Herein, we review established clinical use cases for SARS-CoV-2 antibody measures, which include diagnosis of recent prior infection, isolating high titer convalescent plasma, diagnosing multisystem inflammatory syndrome in children (MIS-C), and booster dosing in the immunosuppressed and other populations. We then address whether an antibody correlate of protection (CoP) for SARS-CoV-2 has been successfully defined with the following considerations: Antibody responses in the immunocompetent, vaccine type, variants, use of binding antibody tests vs. neutralization tests, and endpoint measures.

Cardiac Magnetic Resonance Imaging Versus Computed Tomography to Guide Transcatheter Aortic Valve Replacement: A Randomized, Open-Label, Noninferiority Trial.

Background: Computed tomography (CT) is recommended for guiding transcatheter aortic valve replacement (TAVR). However, a sizable proportion of TAVR candidates have chronic kidney disease, in whom the use of iodinated contrast media is a limitation. Cardiac magnetic resonance imaging (CMR) is a promising alternative, but randomized data comparing the effectiveness of CMR-guided versus CT-guided TAVR are lacking.

The Use of Electroconvulsive Therapy on Death Row.

Despite high rates of mental illness among incarcerated people in the United States, use of electroconvulsive therapy (ECT) remains limited in jails and prisons. There are some published guidelines regarding the provision of mental health care, including ECT, in U.S.

Prevention of Early Sudden Cardiac Death after Myocardial Infarction Using the Wearable Cardioverter Defibrillator-Results from a Real-World Cohort.

Background: After acute myocardial infarction (AMI), patients are at risk of sudden cardiac death. The VEST trial failed to show a reduction in arrhythmic mortality in AMI patients with an LVEF ≤ 35% prescribed with a WCD, having a lower-than-expected WCD wearing compliance.

Objectives: The aim was to investigate on outcomes of patients in a real-world Austrian cohort with good compliance.

Acute Coronary Syndrome Following Transcatheter Aortic Valve Replacement.

Extending the indication of transcatheter aortic valve replacement (TAVR) to younger and lower-risk patients naturally results in longer life expectancy and survival rates after the intervention. The longer life expectancy of these patients leads to an increased possibility of future acute coronary events, necessitating the development of effective and appropriate treatment strategies. Acute coronary syndromes (ACS) in patients with previous TAVR procedures present with modified clinical characteristics when compared to the non-TAVR population.
