Non-eligibility for pivotal HFpEF/HFmrEF outcome trials and mortality in a contemporary heart failure cohort.
Pivotal outcome trials targeting heart failure with preserved (HFpEF) and mildly-reduced ejection fraction (HFmrEF) may have excluded patients at highest risk of poor outcomes. We aimed to assess eligibility for HFpEF/HFmrEF outcome trials in an unselected heart failure cohort and its association with all-cause mortality. Among 32.028 patients presenting to a tertiary care center emergency unit for any reason between August 2018 and July 2019, we identified 407 admissions with evident HFpEF and HFmrEF. ⋯ Exclusion criteria independently predicting death were eGFR <20 ml/min/1.73 m2, COPD with home oxygen therapy, and severe valvular heart disease. Conclusively, in a contemporary HFpEF/HFmrEF cohort, non-eligibility for outcome trials predicted for strongly increased mortality. HFpEF/HFmrEF patients at highest mortality risk were likely underrepresented in previous outcome trials and their treatment remains an unmet medical need.

ReviewWhat changed after the 2022 guidelines for pulmonary hypertension?
With an estimated prevalence of around 1%, pulmonary hypertension (PH) presents a relevant burden worldwide. In this review, we aim to give an overview of the novelties from the revised European Society of Cardiology (ESC) /European Respiratory Society (ERS) guidelines for the diagnosis and treatment of PH and their implication for the everyday clinical practice.

Predicting acute and long-term mortality in a cohort of pulmonary embolism patients using machine learning.
Pulmonary embolism (PE) is a severe condition that causes significant mortality and morbidity. Due to its acute nature, scores have been developed to stratify patients at high risk of 30-day mortality. Here we develop a machine-learning based score to predict 30-day, 90-day, and 365-day mortality in PE patients. ⋯ Machine learning algorithms have improved on standard clinical risk stratification for PE patients. External cohort validation is required before incorporation into clinical workflows.

Elevated levels of IL-6 in IgA nephropathy patients are induced by an epigenetically driven mechanism modulated by viral and bacterial RNA.
Immunoglobulin A nephropathy (IgAN) is the most frequent primary glomerulonephritis and the role of IL-6 in pathogenesis is becoming increasingly important. A recent whole genome DNA methylation screening in IgAN patients identified a hypermethylated region comprising the non-coding RNA Vault RNA 2-1 (VTRNA2-1) that could explain the high IL-6 levels. ⋯ The discovery of the upregulated VTRNA2-1/PKR/CREB/IL-6 pathway in IgAN patients may provide a novel approach to treating the disease and may be useful for the development of precision nephrology and personalized therapy by checking the VTRNA2-1 methylation level in IgAN patients.
