Background: Extracorporeal life support (ECLS) provides organ perfusion in refractory cardiac arrest but during the initiation of ECLS mean arterial pressure (MAP) and carotid flow may be suboptimal due to hypotension and/or insufficient flow. We hypothesized that cardiopulmonary resuscitation (CPR) in addition to ECLS may increase carotid flow and MAP compared to ECLS alone.
Methods: Observational pilot study comparing hemodynamic parameters before and after CPR cessation in pigs supported by ECLS for experimental refractory cardiac arrest.
Objective: To explore the association of maternal characteristics, oxygenation, and mechanical ventilatory parameters with fetal and neonatal outcomes.
Methods: The present study was a multicenter, binational (Argentina/Colombia), prospective, cohort study, conducted in 21 intensive care units (ICUs) and including pregnant or postpartum patients with COVID-19 pneumonia requiring advanced respiratory support and their fetuses/neonates. Advanced respiratory support was defined as high-flow nasal cannula (HFNC), non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV).
Article Synopsis
- - Holography is crucial for advancing various technologies like 3D displays, LiDAR, optical encryption, and AI, by facilitating effective optical information storage and processing.
- - The review discusses the evolution from traditional volume holograms to modern digital holography using ultrathin metasurfaces, highlighting holographic multiplexing and fabrication techniques.
- - The potential applications of metasurface holography are explored, particularly in high bandwidth scenarios that enhance sensitivity to light's orbital angular momentum, with a look towards future advancements in the field.
Article Synopsis
- The study aimed to assess the effectiveness of olaparib in patients with advanced triple negative breast cancer who have homologous recombination deficiency but do not have BRCA1/2 mutations.
- The NOBROLA trial was conducted as a phase IIa study, enrolling patients treated with olaparib, and focused on the clinical benefit rate as the main measurement.
- Out of 114 patients screened, only 6 were eligible; the median follow-up was 8.5 months, showing a clinical benefit rate of 50%, suggesting potential for further research.
Article Synopsis
- The study aimed to assess how combining split-belt treadmill walking with visual feedback distortion could improve gait symmetry, focusing on adaptation and retention effects.
- Participants underwent a 28-minute walking trial involving a baseline, adaptation, and post-adaptation phase, with different feedback methods applied during the adaptation.
- Results showed that combining visual feedback with treadmill walking led to greater improvement and longer retention of step length symmetry compared to using each method alone.
