AI Article Synopsis
- Cardiogenic shock (CS) is a major concern for patients experiencing acute myocardial infarction (AMI), especially those with cancer, who are at higher risk for these conditions.
- A study used data from 2006 to 2018 to compare outcomes of cancer patients with AMI-CS managed with temporary mechanical circulatory support (tMCS) to those without cancer, finding no difference in in-hospital death rates.
- However, patients with cancer had a significantly higher risk of major bleeding during treatment, indicating the need for more focused research on this population in future studies.
Article Abstract
Background: Cardiogenic shock (CS) is the leading cause of death among patients with acute myocardial infarction (AMI) and is managed with temporary mechanical circulatory support (tMCS) in advanced cases. Patients with cancer are at high risk of AMI and CS. However, outcomes of patients with cancer and AMI-CS managed with tMCS have not been rigorously studied.
Methods: Adult patients with AMI-CS managed with tMCS from 2006 to 2018 with and without cancer were identified using the National Inpatient Sample. Propensity score matching (PSM) was performed for variables associated with cancer. Primary outcome was in-hospital death, and secondary outcomes were major bleeding and thrombotic complications.
Results: After PSM, 1287 patients with cancer were matched with 12,870 patients without cancer. There was an increasing temporal trend for prevalence of cancer among patients admitted with AMI-CS managed with tMCS ( < .001). After PSM, there was no difference in in-hospital death (odds ratio [OR], 1.00; 95% CI, 0.88-1.13) or thrombotic complications (OR, 1.10; 95% CI, 0.91-1.34) between patients with and without cancer. Patients with cancer had a higher risk of major bleeding (OR, 1.29; 95% CI, 1.15-1.46).
Conclusions: Among patients with AMI-CS managed with tMCS, cancer is becoming increasingly frequent and associated with increased risk of major bleeding, although there was no difference in in-hospital death. Further studies are needed to further characterize outcomes, and inclusion of patients with cancer in trials of tMCS is needed.

Background: Astrocytes, a major glial cell in the central nervous system (CNS), can become reactive in response to inflammation or injury, and release toxic factors that kill specific subtypes of neurons. Over the past several decades, many groups report that reactive astrocytes are present in the brains of patients with Alzheimer's disease, as well as several other neurodegenerative diseases. In addition, reactive astrocyte sub-types most associated with these diseases are now reported to be present during CNS cancers of several types.

Growing evidence shows that epigenetic dysregulation through histone deacetylases (HDACs) plays a critical role in synaptic dysfunction and memory loss in AD, and HDACs have been highlighted as a novel class of anti-Alzheimer targets. Moreover, restoring Wnt/β-catenin signaling, which is greatly suppressed in AD brains, is a promising therapeutic strategy for AD.

Expressed CHRFAM7A, a human restricted gene with carrier frequency of 75% in the human population predicts profound translational significance.
Method: The physiological role of CHRFAM7A in human brain is explored using multiomics approach on 600 post mortem human brain tissue samples (ROSMAP).

Background: Sinonasal mucosal melanoma has poor survival despite multimodality treatment. While the impact of immunotherapy (IT) on metastatic cutaneous melanoma is well-defined, there are relatively little data on sinonasal mucosal melanoma.
Objective: We sought to define immunotherapy outcomes in patients with sinonasal mucosal melanoma.

Background: With the advent of FDA approved anti-amyloid therapy and recognition of increased side effects in APOE e4 carriers, APOE testing is now recommended for patients considering anti-amyloid therapies such as lecanemab. Given the therapeutic implications and anticipated volume of eligible patients, the traditional model of in-person, pre- and post-test genetic counseling is not feasible to incorporate in clinical pathways. Alternative delivery models, including digital tools and telehealth, will be key in providing APOE genetic counseling support.
