Proton Pump Inhibitor Use and Adverse Effects in South Atlantic Hospitals.

Background: Proton pump inhibitors (PPI) have transformed the management of acid-related gastrointestinal disorders, becoming one of the top-selling medications in the United States. There is no doubt that PPIs have a significant therapeutic impact on patients with gastroesophageal reflux disease and gastrointestinal bleeding. However, evidence is mounting that PPIs are overprescribed, leading to more patients possibly experiencing adverse effects.

Correlation of Nutrition with Immune Status in Human Immunodeficiency Virus Outpatients.

Malnutrition has been proven to cause poor outcomes in many chronic diseases. We examined the association between malnutrition and immune status in HIV patients. We used the Nutritional Risk Index to evaluate the nutrition in 812 HIV patients, and correlated this variable with viral loads and CD4 counts.

Wireless solar water splitting using silicon-based semiconductors and earth-abundant catalysts.

We describe the development of solar water-splitting cells comprising earth-abundant elements that operate in near-neutral pH conditions, both with and without connecting wires. The cells consist of a triple junction, amorphous silicon photovoltaic interfaced to hydrogen- and oxygen-evolving catalysts made from an alloy of earth-abundant metals and a cobalt|borate catalyst, respectively. The devices described here carry out the solar-driven water-splitting reaction at efficiencies of 4.

Three-coordinate, phosphine-ligated azadipyrromethene complexes of univalent group 11 metals.

Tetraarylazadipyrromethenes are Lewis basic, red-light absorbing dyes with optical properties conducive to sensing and therapeutic applications. Recently, transition metal complexes of these ligands have been described. Here, we report a series of three-coordinate Group 11 complexes of unsubstituted and methoxy-substituted tetraarylazadipyrromethenes.
