Proteolysis-targeting influenza vaccine strains induce broad-spectrum immunity and in vivo protection.

Generating effective live vaccines from intact viruses remains challenging owing to considerations of safety and immunogenicity. Approaches that can be applied in a systematic manner are needed. Here we created a library of live attenuated influenza vaccines by using diverse cellular E3 ubiquitin ligases to generate proteolysis-targeting (PROTAR) influenza A viruses.

Vaccine Potency and Structure of Yeast-Produced Polio Type 2 Stabilized Virus-like Particles.

Poliovirus (PV) is on the brink of eradication due to global vaccination programs utilizing live-attenuated oral and inactivated polio vaccines. Recombinant PV virus-like particles (VLPs) are emerging as a safe next-generation vaccine candidate for the impending polio-free era. In this study, we investigate the production, antigenicity, thermostability, immunogenicity, and structures of VLPs derived from PV serotype 2 (PV2) wildtype strain and thermally stabilized mutant (wtVLP and sVLP, respectively).

Management of Refractory Status Epilepticus: An International Cohort Study (MORSE CODe) Analysis of Patients Managed in the ICU.

Background And Objectives: Status epilepticus that continues after the initial benzodiazepine and a second anticonvulsant medication is known as refractory status epilepticus (RSE). Management is highly variable because adequately powered clinical trials are missing. We aimed to determine whether propofol and midazolam were equally effective in controlling RSE in the intensive care unit, focusing on management in resource-limited settings.

Phase I study of the anti-FcRH5 antibody-drug conjugate DFRF4539A in relapsed or refractory multiple myeloma.

FcRH5 is a cell surface marker enriched on malignant plasma cells when compared to other hematologic malignancies and normal tissues. DFRF4539A is an anti-FcRH5 antibody-drug conjugated to monomethyl auristatin E (MMAE), a potent anti-mitotic agent. This phase I study assessed safety, tolerability, maximum tolerated dose (MTD), anti-tumor activity, and pharmacokinetics of DFRF4539A in patients with relapsed/refractory multiple myeloma.

Total Anomalous Pulmonary Venous Connection: The Current Management Strategies in a Pediatric Cohort of 768 Patients.

Background: Total anomalous pulmonary venous connection (TAPVC) is a rare form of congenital heart disease. This study describes current surgical treatment strategies and experiences in a cohort of patients from 2 congenital cardiac centers in Shanghai and Guangdong in China.

Methods: This retrospective study included 768 patients operated on between 2005 and 2014.

Effect of N-acetylcysteine on pulmonary function in patients undergoing off-pump coronary artery bypass surgery.

Background: Pulmonary dysfunction related to inflammatory response and radical oxygen species remains a problem in off-pump coronary bypass graft surgery (OPCAB), especially in patients with reduced left ventricular (LV) function. The aim of this study was to evaluate the effect of N-acetylcysteine (NAC) on pulmonary function following OPCAB.

Methods: Patients with LV ejection fraction ≤40% were randomly assigned to receive either a bolus of 100 mg/kg of intravenous NAC over a 15-min period immediately after anesthetic induction, followed by an intravenous infusion at 40 mg/kg/day for 24 h (NAC group, n=24), or a placebo (control group, n=24).

The use of high-resolution computed tomography in the evaluation of pulmonary hemodynamics in patients with congenital heart disease: in pulmonary vessels larger than 1 mm in diameter.

High-resolution computed tomography (HRCT) was carried out in 36 patients with congenital left-to-right shunt disease and 10 normal control subjects to assess the feasibility of CT in the evaluation of pulmonary hemodynamics. The patients had a left-to-right or a bidirectional shunt and the hemodynamic data obtained by cardiac catheterization in these patients were compared to the information obtained by CT imaging. The pulmonary/systemic blood flow (Q(p)/Q(s)) ratio and pulmonic/systemic resistance (R(p)/R(s)) ratio had a significant correlation with the pulmonary artery/bronchus (PA/Br) ratio (r = 0.
