Patient-reported health status is an important assessment of patients with heart failure, but current approaches have substantial methodological and analytical limitations. Changes in the Kansas City Cardiomyopathy Questionnaire (KCCQ) are commonly presented as a measure of the effect of drugs and devices, most often as the between-group difference in population means or as the odds of showing threshold changes of 5, 10, 15, and 20 points. However, the presentation of mean differences is based on statistical assumptions that are routinely violated in most trials.

Advanced Markers for Hemodynamic Monitoring in Cardiogenic Shock and End-Stage Heart Failure: A Mini Review.

Heart Fail Rev

January 2025

Division of Cardiovascular Medicine, University of Utah Health & School of Medicine, 30 N Mario Capecchi Drive, HELIX Building 3rd Floor, Salt Lake City, UT, 84112, USA.

Right heart catheterization (RHC) provides critical hemodynamic insights by measuring atrial, ventricular, and pulmonary artery pressures, as well as cardiac output (CO). Although the use of RHC has decreased, its application has been linked to improved outcomes. Advanced hemodynamic markers such as cardiac power output (CPO), aortic pulsatility index (API), pulmonary artery pulsatility index (PAPi), right atrial pressure to pulmonary capillary wedge pressure ratio (RAP/PCWP) and right ventricular stroke work index (RVSWI) have been introduced to enhance risk stratification in cardiogenic shock (CS) and end-stage heart failure (HF) patients.

Acute myeloid leukemias (AMLs) have an overall poor prognosis with many high-risk cases co-opting stem cell gene regulatory programs, yet the mechanisms through which this occurs remain poorly understood. Increased expression of the stem cell transcription factor, MECOM, underlies one key driver mechanism in largely incurable AMLs. How MECOM results in such aggressive AML phenotypes remains unknown.

VISTA-induced tumor suppression by a four amino acid intracellular motif.

bioRxiv

January 2025

Departments of Medicine and Molecular Biology, Cecil H. and Ida Green Center for Reproductive Sciences, UT Southwestern Medical Center, Dallas, TX, 75235.

VISTA is a key immune checkpoint receptor under investigation for cancer immunotherapy; however, its signaling mechanisms remain unclear. Here we identify a conserved four amino acid (NPGF) intracellular motif in VISTA that suppresses cell proliferation by constraining cell-intrinsic growth receptor signaling. The NPGF motif binds to the adapter protein NUMB and recruits Rab11 endosomal recycling machinery.

Acetyl CoA synthetases (ACS) have emerged as drug targets for the treatment of cancer, metabolic diseases as well as fungal and parasitic infections. Although a variety of small molecule ACS inhibitors have been discovered, the systematic optimization of these molecules has been slowed by a lack of structural information regarding their mechanism of inhibition. Through a chemical genetic-based, synthetic lethal screen of the human fungal pathogen , we identified an isoxazole-based ACS inhibitor with antifungal activity and exquisite selectivity for the Acs1 relative to human ACSS2 as well as other fungal ACSs.

Adverse financial burden and its effect on patients resulting from the costs associated with cancer care, both direct and indirect, is known as financial toxicity. This review explores the interplay between financial toxicity and key social and legal needs in cancer care. Drawing from the WHO's framework and the ASCO's policy statement on social determinants of health, we propose a conceptual model that discusses five key needs-housing insecurity, food insecurity, transportation and access barriers, employment disruptions, and psychosocial needs-which interact with, and are affected by financial toxicity, and adversely influence patients' well-being and adherence to treatment.
