Continuous Renal Replacement Therapy for Hypertension Complicated by Refractory Heart Failure: An Analysis of Safety and Nursing Highlights.

Objective: This research is aimed at analyzing the safety profile and nursing highlights of continuous renal replacement therapy (CRRT) for hypertension (HT) complicated by refractory heart failure (RHF).

Methods: Sixty-six HT + RHF patients admitted between March 2018 and December 2021 were enrolled and assigned to two groups: a CRRT group with 33 cases treated with CRRT and a control group with 33 cases intervened by routine treatment. The therapeutic effect and alterations of cardiac function (CF) indexes were observed in both cohorts.

Removal of petroleum sulfonate from aqueous solutions using freshly generated magnesium hydroxide.

Freshly generated magnesium hydroxide (FGMH), produced by adding water-soluble magnesium salts to highly alkaline solutions, was used to remove anionic surfactant petroleum sulfonate (PS) from aqueous solutions. Adsorption experiments were carried out to investigate the effects of pH, adsorbent dosage, contact time, PS concentration, and temperature. The results showed that FGMH displayed excellent treatment efficiency for PS in the pH range 12.

Daily short-period gravitation can prevent functional and structural changes in arteries of simulated microgravity rats.

This study was designed to clarify whether simulated microgravity-induced differential adaptational changes in cerebral and hindlimb arteries could be prevented by daily short-period restoration of the normal distribution of transmural pressure across arterial vasculature by either dorsoventral or footward gravitational loading. Tail suspension (Sus) for 28 days was used to simulate cardiovascular deconditioning due to microgravity. Daily standing (STD) for 1, 2, or 4 h, or +45 degrees head-up tilt (HUT) for 2 or 4 h was used to provide short-period dorsoventral or footward gravitational loading as countermeasure.
