Continuous risk monitoring and management of heart failure: Rationale and design of the ALLEVIATE-HF trial.
Eur J Heart Fail

Aims: Early identification and management of worsening heart failure (HF) is necessary to prevent disease progression and hospitalizations. The ALLEVIATE-HF (Algorithm Using LINQ Sensors for Evaluation and Treatment of Heart Failure) trial is a prospective, randomized, controlled, double-blind, multicentre trial that aims to assess the safety and efficacy of using the Reveal LINQ™ insertable cardiac monitor (ICM) in patients with HF to continuously monitor and evaluate HF risk status and guide timely interventions.
Methods: The ICM algorithm uses parameters derived from electrocardiogram (atrial fibrillation [AF], ventricular rate during AF, heart rate variability, and night heart rate), three-axis accelerometer (patient activity duration), and subcutaneous bioimpedance (fluid volume, respiration rate).
Carbonic anhydrase 2-derived drug-responsive domain regulates membrane-bound cytokine expression and function in engineered T cells.

Adoptive cell therapies (ACT) have shown reduced efficacy against solid tumor malignancies compared to hematologic malignancies, partly due to the immunosuppressive nature of the tumor microenvironment (TME). ACT efficacy may be enhanced with pleiotropic cytokines that remodel the TME; however, their expression needs to be tightly controlled to avoid systemic toxicities. Here we show T cells can be armored with membrane-bound cytokines with surface expression regulated using drug-responsive domains (DRDs) developed from the 260-amino acid protein human carbonic anhydrase 2 (CA2).

In 2023, the journals "Bioconjugate Chemistry" and "Sensors and Actuators B: Chemical" published two papers describing new biosensors for imaging hypoxic regions in tumors. Cao et al. combined acetazolamide (AZA) to target carbonic anhydrase IX (CA IX) with two tyrosine-derived Mn(II)-ethylenediaminetetraacetic acid chelates (TyEDTA) on a rigid triazine (TA) scaffold.

Angiotensin II receptor antagonists are tetrazole derivatives used in the treatment of high blood pressure, and are also indicated for the treatment of heart failure (NYHA class II-IV). They are used alone or in combination with other classes of antihypertensives or diuretics for the effective management of high blood pressure. In this study, we aim to evaluate the thermal stability and degradation kinetics for the principal compounds used in therapy from this class, namely telmisartan, valsartan, olmesartan medoxomil, and losartan potassium.

Background: Obesity is associated with excessive adipocyte-derived aldosterone secretion, independent of the classical renin-angiotensin-aldosterone cascade, and mineralocorticoid receptor antagonists may be more effective in patients with heart failure (HF) and obesity.
Objectives: This study sought to examine the effects of the nonsteroidal mineralocorticoid receptor antagonist finerenone compared with placebo, according to body mass index (BMI) in FINEARTS-HF (FINerenone trial to investigate Efficacy and sAfety superioR to placebo in paTientS with Heart Failure).
Methods: A total of 6,001 patients with HF with NYHA functional class II, III, and IV, a left ventricular ejection fraction of ≥40%, evidence of structural heart disease, and elevated natriuretic peptide levels were randomized to finerenone or placebo.
