Controlled Nutrient Delivery to Pancreatic Islets Using Polydopamine-Coated Mesoporous Silica Nanoparticles.

In this study, we designed a nanoscale platform for sustained amino acid delivery to support transplanted pancreatic islets. The platform features mesoporous silica nanoparticles (MSNPs) loaded with glutamine (G), an essential amino acid required for islet survival and function, and coated with polydopamine (PD). We investigated various PD concentrations (0.

The impact of antimicrobial stewardship interventions on appropriate use of surgical antimicrobial prophylaxis in low- and middle-income countries: a systematic review.

Background: Surgical antimicrobial prophylaxis (SAP) is an effective infection prevention strategy used to reduce postoperative surgical site infection. Inappropriate use of SAP is a concern in low-middle-income countries (LMICs) due to increased mortality risks, adverse reactions, re-admission rates and length of hospital stay. Antimicrobial Stewardship Programs (ASP) have been shown to be effective in improving the appropriate use of antibiotics including the use of SAP.

First clinical report of the international single-port robotic rectal cancer registry.

Background: Rectal cancer surgery remains a significant technical challenge. The development and implementation of a new technology offer hope for more accurate and precise surgery. To evaluate whether single-port robotic (SPr) technology helps achieve this goal, an international SPr registry was established.

Evaluating the therapeutic potential of different sources of mesenchymal stem cells in acute respiratory distress syndrome.

Background: Mesenchymal stem/stromal cells (MSCs) have attracted interest as a potential therapy given their anti-inflammatory and immunomodulatory properties. However, clinical trials using MSCs for acute respiratory distress syndrome (ARDS) have produced mixed and inconclusive data. In previous work, we performed a "head-to-head" comparison between different sources of MSCs and showed that each source had a unique genomic and proteomic "signature".
