The literature has consistently shown age and education to be associated with eHealth use, while the findings for racial and ethnic disparities are mixed. However, previous disparities may have narrowed as health care interactions shifted to web-based modalities for everyone because of the COVID-19 pandemic.

Glycyrrhizin-enriched extracts from licorice root are associated with numerous health benefits and are widely used in phytotherapy. There is evidence that ingesting glycyrrhizin beyond threshold concentrations can impact the metabolism of cortisol, inhibiting its conversion to an inactive form, cortisone, via 11-hydroxysteroid dehydrogenase. A consequence can be a form of hypermineralocorticoidism, with elevated potassium excretion and associated hypertension, as demonstrated in rats and humans.

Plant species of concern often occupy narrow habitat ranges, making climate change an outsized potential threat to their conservation and restoration. Understanding the physiological status of a species during stress has the potential to elucidate current risk and provide an outlook on population maintenance. However, the physiological status of a plant can be difficult to interpret without a reference point, such as the capacity to tolerate stress before loss of function, or mortality.

Background: Return of spontaneous circulation (ROSC) in the field is a vital determinant contributing to survival from out-of-hospital cardiac arrest (OHCA). However, nearly one third of survivors at the Dallas-Fort Worth (DFW) Resuscitation Outcomes Consortium (ROC) site did not obtain ROSC in the field.

Methods: A retrospective, observational analysis was performed on all adult patients with non-traumatic OHCA treated on scene and transported to hospital, who did not gain ROSC in the field at DFW ROC site between 2006 through 2011.

The context within which health care and public health systems operate is framed by health policies. There is growing consensus about the need for increased health policy leadership and a health professional workforce prepared to assume these leadership roles. At the same time, there is strong evidence supporting the need for a broader policy lens and the need to intentionally target health disparities.

This study identified facilitators and barriers to academic success among ethnic minority students enrolled in a BSN program. The following research questions were asked: What factors (a) facilitate academic performance; (b) are barriers to academic performance; (c) influence the college experience and academic success; (d) within the nursing department, influence academic success; (e) What is the impact of socialization on academic performance; (f) What were facilitators of academic success identified among study participants; and, (g) Which facilitators, identified by subjects, were most common among those participants? A retrospective-descriptive study design consisted of a sample of all minority students who were enrolled in clinical at a baccalaureate nursing program between 2005 and the fall of 2010. Bandura's theory on self-efficacy was used.

Vitamin D, a fat-soluble vitamin naturally present in very few foods, is synthesized when ultraviolet rays from sunlight contact the skin. Research suggests that vitamin D insufficiency may result from lack of exposure to sunlight and ultraviolet-B radiation. Individuals from geographic areas of high latitude and low sunlight exposure may be at increased risk for vitamin D deficiency.

Nurses spend more time with their patients than do other health care workers. Therefore, the spiritual needs of patients must be recognized as a domain of nursing care. Holism cannot exist without consideration of the spiritual aspects that create individuality and give meaning to people's lives.

An 18-week feeding trial was performed to investigate the effects of an omega-3 (n-3) fatty acid-enriched ration on plasma fatty acid concentrations and platelet aggregation in healthy horses. Flaxseed oil served as the source of the n-3 fatty acid alpha-linolenic acid (ALA). Twelve horses were fed dietary maintenance requirements using a complete pelleted ration (80%) and timothy grass hay (20%) for a 2-week acclimation period before being randomly assigned either to a treatment (group 1) or control (group 2) group.
