To investigate the effectiveness and tolerability of lacosamide (LCM) and to select a better reference range for its concentration in plasma for Chinese pediatric patients with epilepsy. In addition, it is necessary to evaluate the potential determinates of LCM concentration. Pediatric epilepsy patients using LCM were retrospective included.

Childhood nephrotic syndrome (NS) is a serious disease affecting the health and quality of life of children, which is characterized by a series of pathophysiological changes due to the increased permeability of the glomerular membrane to plasma proteins. Low renal drug distribution and inefficient cellular uptake, resulting from cellular dysfunctions of filtration and internalization, are the main barriers to drug treatment in childhood NS, leading to deterioration in nephropathy. However, efficient therapeutic methods against childhood NS are still lacking in clinic.

Article Synopsis
  • This study focused on developing population pharmacokinetics (PPK) models for nirmatrelvir/ritonavir in critically ill Chinese patients with COVID-19 to understand how various factors affect the drug's pharmacokinetics.
  • Researchers collected data from 152 patients and analyzed it using advanced modeling techniques, particularly looking at how renal function impacts the drug's clearance and distribution in the body.
  • Results indicated that those with renal impairment experienced significantly altered drug exposure, which could inform better dosing strategies for these patients in clinical settings.

Background: The role of hospital pharmacists has shifted from primarily ensuring drug supply to providing comprehensive pharmaceutical care. To accommodate this shift, new positions are needed. The traditional training model for hospital pharmacists is no longer sufficient for the evolving demands of pharmaceutical care and these new roles.

Introduction: A northern goshawk back-propagation artificial neural network (NGO-BPANN) model was established to predict monohydroxycarbazepine (MHD) concentration in patients with epilepsy.

Methods: The data were collected from 108 Han Chinese patients with epilepsy on oxcarbazepine monotherapy. The results of 14 genotype variates were selected as the input layer in the first BPANN model, and the variables that had a more significant impact on the plasma concentration of MHD were retained.

Vancomycin dosing is difficult in critically ill patients receiving continuous renal replacement therapy (CRRT). Previous population pharmacokinetic (PopPK) models seldom consider the effect of residual diuresis, a significant factor of elimination, and thus have poor external utility. This study aimed to build a PopPK model of vancomycin that incorporates daily urine volume to better describe the elimination of vancomycin in these patients.

Background: Various methods for ex utero culture systems have been explored. However, limitations remain regarding the in vitro culture platforms used before implanting mouse embryos and the normal development of mouse blastocysts in vitro. Furthermore, vascular niche support during mouse embryo development from embryonic day (E) 3.

Article Synopsis
  • The study aimed to implement and evaluate a multidisciplinary Enhanced Recovery After Surgery (ERAS) program specifically for patients undergoing sacral tumor surgery, as existing data were limited.
  • Conducted from March to September 2021, the research included two patient groups: one receiving the ERAS protocols and the other following conventional care, with data collected on various recovery metrics.
  • Results showed that the ERAS group had significantly quicker recovery times, such as shorter times to first ambulation (20.9 hours vs. 104.3 hours) and first flatus, as well as a reduced postoperative length of stay and higher rates of early discharge compared to the No-ERAS group.

Article Synopsis
  • Ischemic stroke requires ICU care and has high mortality rates, but effective predictive tools for patient outcomes are currently lacking.
  • This study introduced the ICU-ISPM model, which uses advanced ensemble learning techniques to predict in-hospital mortality from ischemic stroke, achieving high accuracy in tests.
  • The model identifies key mortality predictors and comes with an online tool for clinicians, helping them assess patient risk and allocate resources more effectively.

Cancer is generally considered a result of genetic mutations that cause epigenetic changes, leading to anomalous cellular behavior. Since 1970s, an increasing understanding of the plasma membrane and specifically the lipid alterations in tumor cells have provided novel insights for cancer therapy. Moreover, the advances in nanotechnology offer a potential opportunity to target the tumor plasma membrane while minimizing side effects on normal cells.

E3 ubiquitin ligases are important components of the ubiquitin protease system. This family includes many proteins, which can catalyze the ubiquitination of a variety of protein substrates and promote the degradation of them by the proteasome system. Recent studies have shown that E3 ubiquitin ligase plays a key role in the process of fetal development and placental formation.

Objective: Congenital cytomegalovirus (cCMV) is the leading environmental cause of hearing loss (HL) among children, affecting four in one thousand newborns. cCMV testing in the US is currently based on clinical diagnosis which does not consistently identify cCMV cases and precludes early intervention to prevent and reduce the severity of HL. We estimated the cost-effectiveness of targeted newborn screening and cCMV testing among newborns compared to clinical diagnosis.

Ligand/receptor-mediated targeted drug delivery has been widely recognized as a promising strategy for improving the clinical efficacy of nanomedicines but is attenuated by the binding of plasma protein on the surface of nanoparticles to form a protein corona. Here, it is shown that ultrasonic cavitation can be used to unravel surface plasma coronas on liposomal nanoparticles through ultrasound (US)-induced liposomal reassembly. To demonstrate the feasibility and effectiveness of the method, transcytosis-targeting-peptide-decorated reconfigurable liposomes (LPGLs) loaded with gemcitabine (GEM) and perfluoropentane (PFP) are developed for cancer-targeted therapy.

Self-spiraling actuators are widely found in nature and have high research and actuator-application value in self-lock and self-assembly. Four-dimensional (4D) printing is a new generation additive manufacturing of smart materials and has shown great potential for the fabrication of multi-functional and customized structures. The microarchitecture design of a bilayer actuator could bring flexible and diversified self-spiraling behaviors and more possibilities for practical application by combing 4D printing.

We study the non-adiabatic dynamics of a typical symmetry-protected topological (SPT) phase-the Haldane insulator (HI) phase with broken bond-centered inversion. By continuously breaking the middle chain, we find the gap closes at a critical point in the deep HI regime with a change of particle number partition of the left or right system. The adiabatic evolution fails at this critical point and we show how to predict the dynamics of the entanglement entropy near this point using a two-level model.

Background: Despite years of research, porcine-induced pluripotent stem cells (piPSCs) with germline chimeric capacity have not been established. Furthermore, the key transcription factors (TFs) defining the naïve state in piPSCs also remain elusive, even though TFs in the inner cell mass (ICM) are believed to be key molecular determinants of naïve pluripotency. In this study, interferon regulatory factor 1 (IRF-1) was screened to express higher in ICM than trophectoderm (TE).

Background: Postoperative pulmonary complications (PPCs) seems to be high in patients undergoing pelvic and sacrum tumor resection assisted by abdominal aortic balloon occlusion. We hypothesized that the accumulative occlusion time (AOT) of the abdominal aortic balloon may be predictive of PPCs. The objective of the study was to identify the influence of AOT on PPCs.
