Rapid curing dynamics of PEG-thiol-ene resins allow facile 3D bioprinting and in-air cell-laden microgel fabrication.

Thiol-norbornene photoclick hydrogels are highly efficient in tissue engineering applications due to their fast gelation, cytocompatibility, and tunability. In this work, we utilized the advantageous features of polyethylene glycol (PEG)-thiol-ene resins to enable fabrication of complex and heterogeneous tissue scaffolds using 3D bioprinting and in-air drop encapsulation techniques. We demonstrated that photoclickable PEG-thiol-ene resins could be tuned by varying the ratio of PEG-dithiol to PEG norbornene to generate a wide range of mechanical stiffness (0.

The Venezuelan diaspora: Migration-related experiences and mental health.

Since 2015, the Venezuelan diaspora has poured forth from the Venezuelan sending context into an array of (mostly) middle-income receiving countries and into the United States (US) as well. For many Venezuelan migrants, post-migration reception has been mixed, and multiple studies suggest that mental health is an important challenge with discrimination and negative context reception contributing to mental health burden in terms of depression, anxiety, and posttraumatic stress. Cross-national research points to important sociodemographic differences between Venezuelan migrants resettled in South American contexts and in the US, and suggests that-on average-migration-related cultural stress is lower and mental health outcomes are better among those resettling in South Florida and elsewhere in the US.

Microfluidic Synthesis of Microgel Building Blocks for Microporous Annealed Particle Scaffold.

The microporous annealed particle (MAP) scaffold platform is a subclass of granular hydrogels. It is composed of an injectable slurry of microgels that can form a structurally stable scaffold with cell-scale porosity in situ following a secondary light-based chemical crosslinking step (i.e.

Plasma CD59 concentrations are increased in preeclampsia with severe features and correlate with laboratory measures of end-organ injury.

Objectives: Dysregulation of CD59 may lead to increased complement-mediated end-organ injury in preeclampsia. We sought to determine if soluble CD59 concentrations are altered in preeclampsia with severe features.

Study Design: Observational case-control study, which enrolled subjects prospectively from six centers in Colombia from 2015 to 2016.

Surgical site infection in abdominal trauma patients: risk prediction and performance of the NNIS and SENIC indexes.

Background: The National Nosocomial Infections Surveillance (NNIS) and Efficacy of Nosocomial Infection Control (SENIC) indexes are designed to develop control strategies and to reduce morbidity and mortality rates resulting from infections in surgical patients. We sought to assess the application of these indexes in patients undergoing surgery for abdominal trauma and to develop an alternative model to predict surgical site infections (SSIs).

Methods: We conducted a prospective cohort study between November 2000 and March 2002.
