Background And Aims: An expansion of fat mass is an integral feature of patients with heart failure and preserved ejection fraction (HFpEF). While body mass index (BMI) is the most common anthropometric measure, a measure of central adiposity-the waist-to-height ratio (WHtR)-focuses on body fat content and distribution; is not distorted by bone or muscle mass, sex, or ethnicity; and may be particularly relevant in HFpEF.

Methods: The PARAGON-HF trial randomized 4796 patients with heart failure and ejection fraction ≥45% to valsartan or sacubitril/valsartan.

Comparative studies on the development of nervous systems have a significant impact on understanding animal nervous system evolution. Nevertheless, an important question is to what degree neuronal structures, which play an important role in early stages, become part of the adult nervous system or are relevant for its formation. This is likely in many direct developers, but it is not the case in forms with catastrophic metamorphosis.

Autoimmune pulmonary alveolar proteinosis (aPAP), which accounts for >90% of all cases of PAP, is a rare lung disease mediated by granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies that block GM-CSF signalling, leading to reduced surfactant clearance causing abnormal accumulation of alveolar surfactant and impaired gas exchange [1-3]. The current standard of care for aPAP is whole-lung lavage (WLL), which is invasive, resource intensive, carries procedural risk, does not address the underlying cause of disease and often must be repeated regularly [4]. Hence, there is a therapeutical need to address the underlying pathophysiology of the disease.

The reason why certain bacteria, , (PA), produce acetylated alginate (Alg) in their biofilms remains one of the most intriguing facts in microbiology. Being the main structural component of the secreted biofilm, like the one formed in the lungs of cystic fibrosis (CF) patients, Alg plays a crucial role in protecting the bacteria from environmental stress and potential threats. Nonetheless, to investigate the PA biofilm environment and its lack of susceptibility to antibiotic treatment, the currently developed biofilm models use native seaweed Alg, which is a non-acetylated Alg.

Immunity suffers a function deficit during aging, and the incidence of cancer is increased in the elderly. However, most cancer models employ young mice, which are poorly representative of adult cancer patients. We have previously reported that Triple-Therapy (TT), involving antigen-presenting-cell activation by vinorelbine and generation of TCF1-stem-cell-like T cells (scTs) by cyclophosphamide significantly improved anti-PD-1 efficacy in anti-PD1-resistant models like Triple-Negative Breast Cancer (TNBC) and Non-Hodgkin's Lymphoma (NHL), due to T-cell-mediated tumor killing.

While the effect of amplification-induced oncogene expression in cancer is known, the impact of copy-number gains on "bystander" genes is less understood. We create a comprehensive map of dosage compensation in cancer by integrating expression and copy number profiles from over 8000 tumors in The Cancer Genome Atlas and cell lines from the Cancer Cell Line Encyclopedia. Additionally, we analyze 17 cancer open reading frame screens to identify genes toxic to cancer cells when overexpressed.

Congenital platelet disorders are rare and targeted treatment is usually not possible. Inherited platelet function disorders (iPFDs) can affect surface receptors and multiple platelet responses such as defects of platelet granules, signal transduction, and procoagulant activity. If iPFDs are also associated with a reduced platelet count (thrombocytopenia), it is not uncommon to be misdiagnosed as immune thrombocytopenia.
