Physiological adaptation in flagellar architecture improves chemotaxis in complex environments.

Bacteria navigate natural habitats with a wide range of mechanical properties, from the ocean to the digestive tract and soil, by rotating helical flagella like propellers. Species differ in the number, position, and shape of their flagella, but the adaptive value of these flagellar architectures is unclear. Many species traverse multiple types of environments, such as pathogens inside and outside a host.

Pharmaceutical versus Over-the-Counter Potassium Citrate: A Benchtop Comparison.

Introduction: Potassium citrate has been shown to significantly reduce kidney stone recurrence by alkalinizing urine and increasing citrate excretion. However, the cost of potassium citrate can be prohibitive. Thus, over-the-counter use of potassium citrate supplements has gained interest from patients and providers due to reported decreased cost.

Dry Needling and Acupuncture in Treatment of Dance-Related Injuries, MD, and PT Perspectives.

Dancers frequently present to health care professionals with musculoskeletal impairments. The role of the health care practitioner, whether physician, physical therapist, or acupuncturist, is to decrease pain and restore function in the short term and to restore adaptive potential and neural connectivity in the long term. When dysfunction is treated, pain improves.

Urban-Rural Inequities in Acute Stroke Care and In-Hospital Mortality.

Background And Purpose: The rural-urban life-expectancy gap is widening, but underlying causes are incompletely understood. Prior studies suggest stroke care may be worse for individuals in more rural areas, and technological advancements in stroke care may disproportionately impact individuals in more rural areas. We sought to examine differences and 5-year trends in the care and outcomes of patients hospitalized for stroke across rural-urban strata.

Trends in Hospital Mortality for Uninsured Rural and Urban Populations, 2012-2016.

Purpose: Rural-urban health disparities have received increasing scrutiny as rural individuals continue to have worse health outcomes. However, little is known about how insurance status contributes to urban-rural disparities. This study characterizes how rural uninsured patients compare to the urban uninsured, determines whether rurality among the uninsured is associated with worse clinical outcomes, and examines how clinical outcomes based on rurality have changed over time.

Nutrition Education Services Described on National Cancer Institute (NCI)-Designated Cancer Center Websites.

For women diagnosed with breast cancer, healthy weight and enhanced nutrition may improve outcomes. The goal of this study is to examine the nutrition education services available on National Cancer Institute (NCI)-Designated Cancer Centers' websites. In 2017, websites of all 61 NCI-Designated Cancer Centers that provide adult clinical care were reviewed at least twice.

The aging spine in sports.

1. Masters athletes may experience low back pain from multiple sources. Masters athletes with discogenic back pain should avoid or modify sports with combined rotational and compressive forces; individuals with facet-mediated pain should avoid or modify sports with excessive extension and rotation.
