Synergistic effects of microplastic and lead trigger physiological and biochemical impairment in a mangrove crab.

Microplastics (MP) are vectors for other environmental contaminants, such as metals, being a considerable problem, especially in the aquatic ecosystem. To investigate the combined effects of MP (high density polyethylene) with lead (Pb), we exposed the mangrove fiddler crab Minuca vocator to Pb (50 mg L), and MP (25 mg L) alone and in mixture, for 5 days. We aimed to determine Pb and MP bioaccumulation, as well as physiological (oxygen consumption and hemolymph osmolality) and biochemical (superoxide dismutase, catalase, glutathione peroxidase, and lipid peroxidation) traits effects.

Infections preceding the development of Dercum disease.

Dercum Disease (DD) is a rare inflammatory disease of painful subcutaneous fat masses with known alterations in lymphatic vessels. DD masses vary from pearl to walnut-size or larger and occur anywhere in body fat. Signs and symptoms of DD are similar to fibromyalgia.

Improving transplant discharge education using a structured teaching approach.

Context: Nonadherence to posttransplant regimens is common in transplant patients and has the potential for devastating consequences, including acute rejection, graft loss, decreased quality of life, and even death. Comprehensive education of patients and families that improves their understanding of posttransplant regimens and self-care techniques can increase adherence and improve outcomes. Transplant recipients have to learn a vast amount of complex information in a short period as they recover from major surgery and cope with the emotional stress of transplantation.

Peer education: an innovative approach for integrating standards into practice.

The purpose of this article is to describe how a nurse-driven peer education process was developed, implemented, and evaluated to improve the integration of new patient care standards into practice. This process was an innovative, interactive, and nonjudgmental approach to learning, whereby the staff members participated in the education and development of their peers. It allowed nurses to expand their knowledge base, critical thinking, and clinical skills, which were evident in their daily practice.
