Association and Dose-Response Relationship of Self-Reported Physical Activity and Disability Among Adults ≥50 Years: National Health and Nutrition Examination Survey, 2011-2016.

Disability is a tremendous public health challenge. No study has assessed whether meeting U.S.

Onset of Antarctic Circumpolar Current 30 million years ago as Tasmanian Gateway aligned with westerlies.

Earth's mightiest ocean current, the Antarctic Circumpolar Current (ACC), regulates the exchange of heat and carbon between the ocean and the atmosphere, and influences vertical ocean structure, deep-water production and the global distribution of nutrients and chemical tracers. The eastward-flowing ACC occupies a unique circumglobal pathway in the Southern Ocean that was enabled by the tectonic opening of key oceanic gateways during the break-up of Gondwana (for example, by the opening of the Tasmanian Gateway, which connects the Indian and Pacific oceans). Although the ACC is a key component of Earth's present and past climate system, the timing of the appearance of diagnostic features of the ACC (for example, low zonal gradients in water-mass tracer fields) is poorly known and represents a fundamental gap in our understanding of Earth history.

Impact of a sepsis educational program on nurse competence.

Sepsis is an emerging life-threatening entity and a worldwide epidemic. Nurses are in key positions to identify patients with sepsis, mobilize the medical team, and implement interventions. A study of self-assessed nurse competence was conducted to determine the influence of a specially designed sepsis education program on nurses' perceived ability to identify early, intervene, and care for patients with sepsis.

Specialized new graduate RN pediatric orientation: a strategy for nursing retention and its financial impact.

New graduate RN retention in the first year of employment is a challenge for hospitals, ranging from a low of 25% to a high of 64%. In 2005, hospitals in New York state spent 11.7% of their nursing budgets on temporary nursing staffing.

A review of current clinical photography guidelines in relation to smartphone publishing of medical images.

The rise in popularity of smartphones has seen a surge in the number of smartphone-specific software applications (apps) available. Among these apps, many are medical and healthcare related, of benefit to both the general public and healthcare staff. With this improved technology comes the ability to display full-colour images and videos, for which medical images could be utilised.

Leadership initiatives to disseminate the institute of medicine's future of nursing report.

This article discusses the critical role professional nurses will play and the tremendous impact nursing education and leadership development will have on the future of health care, as outlined in the recommendations of the Institute of Medicine's report, "The future of nursing: Leading change, and advancing health." Six doctorate of nursing practice students from Case Western Reserve University analyzed the Institute of Medicine (IOM) report and developed projects to disseminate key components to selected organizations. The students developed two primary initiatives.

Permanent El Niño-like conditions during the Pliocene warm period.

During the warm early Pliocene (approximately 4.5 to 3.0 million years ago), the most recent interval with a climate warmer than today, the eastern Pacific thermocline was deep and the average west-to-east sea surface temperature difference across the equatorial Pacific was only 1.

A transient rise in tropical sea surface temperature during the Paleocene-Eocene thermal maximum.

The Paleocene-Eocene Thermal Maximum (PETM) has been attributed to a rapid rise in greenhouse gas levels. If so, warming should have occurred at all latitudes, although amplified toward the poles. Existing records reveal an increase in high-latitude sea surface temperatures (SSTs) (8 degrees to 10 degrees C) and in bottom water temperatures (4 degrees to 5 degrees C).
