Abstract
While the administration of intravenous (IV) iron to those with heart failure has been implicated to be associated with a possible reduction in hospitalizations and improvement in symptoms, a recent large multicenter trial only showed modest benefits in reducing hospitalization, necessitating the updated systematic review. We conducted a systematic review and meta-analysis, searching the MEDLINE and EMBASE database until January 9, 2023. Outcomes included total heart failure hospitalizations, first heart failure hospitalization, six-minute walk test (6MWT) distance, and incidence of infection. There were 13 studies with 3410 participants (1,790 with IV iron). Pooled analysis that reported the incidence of cardiovascular death showed that patients with IV iron did not have significantly lower odds of cardiovascular death or first heart failure hospitalization. In contrast, those who received IV iron had significantly lower total heart failure hospitalization (pooled odds ratio (OR) 0.63, 95% confidence interval (CI) 0.44-0.90, I2 59.0%, P = .017) and a composite of cardiovascular death and first heart failure hospitalization (pooled OR 0.55, 95% CI 0.47-0.64, I2 0%, P = .656). While the efficacy is modest, IV iron therapy could be associated with reduced hospitalization for heart failure without significant adverse events.

Abstract
Cave-dwelling animals have evolved a series of morphological and behavioral traits to adapt to their perpetually dark and food-sparse environments. Among these traits, foraging behavior is one of the useful windows into functional advantages of behavioral trait evolution. Presented herein are updated methods for analyzing vibration attraction behavior (VAB: an adaptive foraging behavior) and imaging of associated mechanosensors of cave-adapted tetra, Astyanax mexicanus. In addition, methods are presented for high-throughput tracking of a series of additional cavefish behaviors including hyperactivity and sleep-loss. Cavefish also show asociality, repetitive behavior and higher anxiety. Therefore, cavefish serve as an animal model for evolved behaviors. These methods use free-software and custom-made scripts that can be applied to other types of behavior. These methods provide practical and cost-effective alternatives to commercially available tracking software.

Abstract
A new activator for the coupling of phosphoramidites to the 5'-hydroxyl group during oligonucleotide synthesis is introduced. The observed time to complete coupling is twice as fast with 4, 5-dicyanoimidazole (DCI) as the activator, compared with 1 H -tetrazole. The effectiveness of DCI is thought to be based on its nucleophilicity. DCI is soluble in acetonitrile up to 1.1 M at room temperature and can be used as the sole coupling activator during routine automated solid phase synthesis of oligonucleotides. The addition of 0.1 M N -methylimidazole to 0.45 M 1 H -tetrazole also results in higher product yields during oligonucleotide synthesis than observed with 1 H -tetrazole alone.
