Introduction: Non-cancer deaths are now becoming a significant threat to the health of cancer patients. Death from stomach and duodenal ulcer is linked to cancer due to the side effects of treatment and its pathogenesis. However, guidelines for identifying cancer patients at the highest risk of death from stomach and duodenal ulcer remain unclear.

Heart transplantation remains a critical therapy for patients with end-stage heart failure, offering incremental survival and improved quality of life. One of the key components behind the success of heart transplantation is the condition and preservation of the donor's heart. In this review, we provide a comprehensive overview of ischemic reperfusion injury, risk factors associated with primary graft dysfunction, current use of various preservation solutions for organ procurement, and recent advancements in donor heart procurement technologies.

Heart failure with preserved ejection fraction (HFpEF) is a major public health challenge, affecting millions worldwide and placing a significant burden on healthcare systems due to high hospitalization rates and limited treatment options. HFpEF is characterized by impaired cardiac relaxation, or diastolic dysfunction. However, there are no therapies that directly treat the primary feature of the disease.

Portopulmonary hypertension (POPH), a form of pulmonary artery hypertension, occurs because of portal hypertension. Pulmonary hemodynamics and right heart function are key entities that are considered when diagnosing and treating POPH. Medical management, combined with liver transplantation, offers a unique opportunity of POPH "cure," however transplant risk can be significant as it relates to the severity of POPH.

Acute electrical stimulation of the common peroneal nerve (cPNS) has been shown to cause an immediate reduction in systolic blood pressure (SBP) in spontaneous hypertense rats (SHR), but the effect of this treatment in sub-chronic ambulatory SBP is unknown. Here we developed an implantable wireless WNClip neural stimulator to test the efficacy of 5-week cPNS as a treatment for hypertension. Daily cPNS 2 Hz monophasic stimulation at threshold for 8 minutes every day for five weeks, reduced SBP in WKY animals by -4 mm Hg, and in SHR animals by -21 mmHg in week 5 (p < 0.

Background: Defining qualitative grades of echocardiographic metrics of right heart chamber size and function is critical for screening, clinical assessment, and measurement of therapeutic response in individuals with pulmonary vascular disease (PVD). In a population enriched for PVD, we sought to establish qualitative grades and prognostic value of right heart chamber size and function.
Methods: We investigated 1053 study participants in the Redefining Pulmonary Hypertension through PVD Phenomics program (PVDOMICS) to determine clinical and echocardiographic differences associated with increasing pulmonary vascular resistance (PVR) severity.

Introduction: While left ventricular ejection fraction (LVEF) represents an important means by which to classify patients with heart failure (HF), relatively little is known about the distribution of LVEFs among patients hospitalized for HF based on their International Classification of Disease (ICD)-10 code.
Methods: We performed a retrospective cross-sectional analysis of patients admitted to a large integrated health system within the western US between January 1, 2018 and October 1, 2022 with a principal diagnosis of HF (defined by ICD-10 codes: I50.2, systolic HF; I50.

In muscle, titin proteins connect myofilaments together and are thought to be critical for contraction, especially during residual force enhancement (RFE) when steady-state force is elevated after an active stretch. We investigated titin's function during contraction using small-angle X-ray diffraction to track structural changes before and after 50% titin cleavage and in the RFE-deficient, titin mutant. We report that the RFE state is structurally distinct from pure isometric contractions, with increased thick filament strain and decreased lattice spacing, most likely caused by elevated titin-based forces.

Aims: Atrial Fibrillation (AF) is one of the most strongly associated risk factors for stroke. Our study aims to analyze changes in mortality from 1999 to 2020 in patients with AF and stroke.
Methods: Using the Centre for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC-WONDER), we retrospectively analyzed annual age-adjusted mortality rates (AAMR) per million from 1999 to 2020 in stroke patients with AF.

Background: Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) are adjunctive intracoronary imaging modalities used to optimize coronary stent implantation. However, the impact of OCT versus IVUS on clinical outcomes and periprocedural complications is unclear.
Aims: To perform a meta-analysis of all vetted randomized controlled trials comparing OCT-guided versus IVUS-guided percutaneous coronary intervention.

Former American football players are at risk for developing traumatic encephalopathy syndrome (TES), the clinical disorder associated with neuropathologically diagnosed chronic traumatic encephalopathy (CTE). The objective of this study was to determine whether hyposmia is present in traumatic encephalopathy syndrome. The study included 119 former professional American football players, 60 former college football players, and 58 same-age asymptomatic unexposed men from the DIAGNOSE CTE Research Project.

Alterations of mitochondrial bioenergetics and arginine metabolism are universally present and mechanistically linked to pulmonary arterial hypertension (PAH), but there is little knowledge of arginine metabolism and mitochondrial functions across the different pulmonary hypertension (PH) groups. We hypothesize that abnormalities in mitochondrial functions are present across all PH groups and associated with clinical phenotypes. We test the hypothesis in PH patients and healthy controls from the Pulmonary Vascular Disease Phenomics Program cohort, who had comprehensive clinical phenotyping and follow-up for at least 4 years for death or transplant status.

Background: Multidisciplinary cardiogenic shock (CS) programs have been associated with improved outcomes, yet practical guidance for developing a CS program is lacking.
Methods: A survey on CS program development and operational best practices was administered to 12 institutions in diverse sociogeographic regions and practice settings. Common steps in program development were identified.
Background: The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021 provides a comprehensive assessment of health and risk factor trends at global, regional, national, and subnational levels. This study aims to examine the burden of diseases, injuries, and risk factors in the USA and highlight the disparities in health outcomes across different states.
Methods: GBD 2021 analysed trends in mortality, morbidity, and disability for 371 diseases and injuries and 88 risk factors in the USA between 1990 and 2021.

Implantable cardioverter-defibrillators (ICDs) are recommended to reduce the risk of sudden cardiac death (SCD) in patients with heart failure with reduced ejection fraction (HFrEF). The landmark studies leading to the current guideline recommendations preceded the 4 pillars of guideline-directed medical therapies (GDMTs). Therefore, some have questioned the role of ICDs for primary prevention in current clinical practice.

This report is a summary of the presentations given at the European Respiratory Society's Research Seminar on Asthma Prevention. The seminar reviewed both epidemiological and mechanistic studies and concluded that; (i) reducing exposure of pregnant women and children to air pollution will reduce incident asthma, (ii) there are promising data that both fish oil and a component of raw cow's milk prevent asthma, and (iii) modulating trained immunity by either mimicking helminth infection or oral and sublingual bacterial products is a promising area of research.
