This amends previous observations that tsRNAs guide Argonaute proteins to silence their targets via a miRNA-like 5' seed match and suggests a yet unknown mechanism of regulation. piperacillin chemical structure Finally, our data suggests that some 5' tRHs are also able to sequence-specifically stabilize mRNAs as upregulated mRNAs are also significantly enriched for 5' tRH target sites.

Dirithromycin is a derivative of the prototype macrolide erythromycin with additional hydrophobic side chain. In our recent study, we have discovered that the side chain of dirithromycin forms lone pair-π stacking interaction with the aromatic imidazole ring of the His69 residue in ribosomal protein uL4 of the Thermus thermophilus 70S ribosome. In the current work, we found that neither the presence of the side chain, nor the additional contact with the ribosome improve the binding affinity of dirithromycin to the ribosome. Nevertheless, we found that dirithromycin is a more potent inhibitor of in vitro protein synthesis in comparison with its parent compound, erythromycin. Using high-resolution cryo-electron microscopy, we determined the structure of the dirithromycin bound to the translating Escherichia coli 70S ribosome, which suggests that the better inhibitory properties of the drug could be rationalized by the side chain of dirithromycin pointing into the lumen of the nascent peptide exit tunnel, where it can interfere with the normal passage of the growing polypeptide chain.

METHODS This retrospective analysis included patients from the Nationwide Readmissions Database with AMI who underwent PCI during 2013-2014. We used multivariable logistic regression model to calculate adjusted odds ratios (AORs) for risk of readmission. To examine potential non-linear association, we performed logistic regression with restricted cubic splines (RCS). RESULTS Of the 492 550 patients with AMI aged above 18 years undergoing PCI during the index hospitalisation, 48 630 (9.87%) were readmitted within 30 days. Although the crude readmission rate of younger patients (aged 18-54 years) was the lowest (7.27%), younger patients had higher risk of readmission compared with patients aged 55-64 years for all-causes (AOR 1.06 (1.01 to 1.11), p=0.0129) and specific causes, such as AMI and chest pain (both cardiac and non-specific) after adjusted for covariates. Patients aged 65-74 years were at lower risk of all-cause readmission. Older patients (age ≥75 years) had higher risk of readmission for heart failure (AOR 1.50 (1.29 to 1.74)) and infection (AOR 1.44 (1.16 to 1.79)), but lower risk for chest pain. RCS analyses showed a U-shaped relationship between age and readmission risk. CONCLUSIONS Our results suggest higher risk of readmission in younger patients for all-cause unplanned readmission after adjusted for covariates. The trends of readmission risk along with age were different for specific causes. Age-targeted initiatives are warranted to reduce preventable readmissions in patients with AMI undergoing PCI. © Author(s) (or their employer(s)) 2020. No commercial re-use.

METHODS The study was a multicentre, randomised assessment of an exercise intervention in patients with ACS ≥70 years with reduced physical performance (as defined by the short physical performance battery (SPPB), value 4-9). The exercise intervention included four supervised sessions (1, 2, 3, 4 months after discharge) and home-based exercises. The control group attended a health education programme only. The outcomes were the 6-month and 1-year effects on physical performance, daily activities, anxiety/depression and quality of life. Finally, 1-year occurrence of adverse events was recorded. RESULTS Overall, 235 patients with ACS (median age 76 (73-81) years) were randomised 1 month after ACS. Exercise and control groups were well balanced. Exercise intervention improved 6-month and 1-year grip strength and gait speed. Exercise intervention was associated with a better quality of life (as measured by EuroQol-visual analogue scale at 6 months 80 (70-90) vs 70 (50-80) points, p less then 0.001 and at 1 year 75 (70-87) vs 65 (50-80) points, p less then 0.001) and with a reduced perception of anxiety and/or depression (6 months 21% vs 42%, p=0.001; 1 year 32% vs 47%, p=0.03). The occurrence of cardiac death and hospitalisation for cardiac cause was lower in the intervention group (7.5% vs 17%, p=0.04). CONCLUSIONS The proposed early, tailored, low-cost exercise intervention improves mobility, daily activities, quality of life and outcomes in older patients with ACS. Larger studies are needed to confirm the clinical benefit. TRIAL REGISTRATION NUMBER NCT03021044. © Author(s) (or their employer(s)) 2020. No commercial re-use. See rights and permissions.

OBJECTIVES The purpose of this study was to examine the association of annual household income and cardiovascular outcomes in individuals with AF. METHODS We analysed administrative claims for individuals with AF from 2009 to 2015 captured by a health claims database. We categorised estimates of annual household income as less then $40 000; $40-$59 999; $60-$74 999; $75-$99 999; and ≥$100 000. Covariates included demographics, education, cardiovascular disease risk factors, comorbid conditions and anticoagulation. We examined event rates by income category and in multivariable-adjusted models in reference to the highest income category (≥$100 000). RESULTS Our analysis included 336 736 individuals (age 72.7±11.9 years; 44.5% women; 82.6% white, 8.4% black, 7.0% Hispanic and 2.1% Asian) with AF followed for median (25th and 75th percentile) of 1.5 (95% CI 0.6 to 3.0) years.
