Global and Community Health: Neurologic Care and a Case Study for Immigrants and Refugees in West Philadelphia.

Philadelphia is a diverse city that has experienced an increasing immigrant and refugee population in recent decades. Although many academic medical centers also call Philadelphia their home, lack of accessibility and difficulty with insurance limit access to health care for many of its newest residents. The Social Health and Medical Services (SHAMS) Free Health Clinic was started to help address some of these disparities, especially for immigrant and refugee populations.

Accuracy and limitations of the bond polarizability model in modeling of Raman scattering from molecular dynamics simulations.

Calculation of Raman scattering from molecular dynamics (MD) simulations requires accurate modeling of the evolution of the electronic polarizability of the system along its MD trajectory. For large systems, this necessitates the use of atomistic models to represent the dependence of electronic polarizability on atomic coordinates. The bond polarizability model (BPM) is the simplest such model and has been used for modeling the Raman spectra of molecular systems but has not been applied to solid-state systems.

Insufficient and biased representation of species geographic responses to climate change.

The geographic redistributions of species due to a rapidly changing climate are poised to perturb ecological communities and significantly impact ecosystems and human livelihoods. Effectively managing these biological impacts requires a thorough understanding of the patterns and processes of species geographic range shifts. While substantial recent redistributions have been identified and recognized to vary by taxon, region, and range geometry, there are large gaps and biases in the available evidence.

A Qualitative Analysis of Barriers to Evidence-Based Care in the Prehospital Management of Patients with Suspected Acute Coronary Syndrome.

Objectives: Prehospital electrocardiogram (ECG) and administration of aspirin are evidence-based strategies for patients with acute coronary syndrome (ACS). However, emergency medical services (EMS) compliance in patients with suspected ACS varies widely. We sought to understand the barriers to prehospital ECG acquisition and aspirin administration for patients with suspected ACS.
