Background And Aims: In patients with heart failure (HF), differences in the association between estimated protein intake (PI) and prognosis in those with and without chronic kidney disease (CKD) remain to be clarified. This study aimed to investigate whether the prognostic effects of the estimated PI differ between patients with HF with and without CKD.

Methods: We included patients who required hospitalisation owing to worsening HF between 2015 and 2019 and assessed the estimated PI based on the adjusted Maroni formula using the body mass index and urinary urea nitrogen level.

Article Synopsis
  • Sleep apnea is common in patients with heart failure and can worsen their health outcomes; the study examines the effects of tofogliflozin, an SGLT2 inhibitor, on this condition.
  • In the study, tofogliflozin significantly lowered the apnea-hypopnea index (AHI) in patients after 6 months, indicating reduced severity of sleep apnea.
  • Improvements in body weight and water content were seen alongside the reduction in AHI, suggesting a possible link between decreased body water and sleep apnea severity, while cardiorenal functions remained unchanged.

Sleep disordered breathing (SDB) is a common comorbidity in patients with atrial fibrillation (AF). Patients undergoing pulmonary vein isolation (PVI) for AF have a high prevalence of SDB. In previous studies, some patients with AF had Cheyne-Stokes respiration (CSR).

Article Synopsis
  • - Ozone gas is effective for disinfecting air and surfaces due to its antiviral and antibacterial properties, but too much exposure can be harmful to humans, making monitoring essential
  • - Current ozone indicators only measure exposure at the end of the exposure period and are limited by a single color dye, which complicates monitoring under varying conditions
  • - The study aimed to create a two-color ozone indicator that shows a wide range of exposure levels through visible changes, improving safety and reliability during both endpoints and ongoing exposure.
