Urgent care centers in the U.S.: Findings from a national survey

<p>Abstract</p> <p>Background</p> <p>Due to long waits for primary care appointments and extended emergency department wait times, newer sites for episodic primary care services, such as urgent care centers, have developed. However, little is known about these centers. The purpose of this study is to provide information about the organization and functioning of urgent care centers based on a nationally representative U.S. sample.</p> <p>Methods</p> <p>We conducted a mail survey with telephone follow-up of urgent care centers identified via health insurers' websites, internet searches, and a trade association mailing list. Descriptive statistics are presented.</p> <p>Results</p> <p>Urgent care centers are open beyond typical office hours, and their scope of services is broader than that of many primary care offices. While these characteristics are similar to hospital emergency departments, such centers employ significant numbers of family physicians. The payer distribution is similar to that of primary care, and physicians' average salaries are comparable to those for family physicians overall. Urgent care centers report early adoption of electronic health records, though our findings are qualified by a lack of strictly comparable data.</p> <p>Conclusion</p> <p>While their hours and scope of services reflect some characteristics of emergency departments, urgent care centers are in many ways similar to family medicine practices. As the health care system evolves to cope with expanding demands in the face of limited resources, it is unclear how patients with episodic care needs will be treated, and what role urgent care centers will play in their care.</p

Trace elements in hemodialysis patients: a systematic review and meta-analysis

<p>Abstract</p> <p>Background</p> <p>Hemodialysis patients are at risk for deficiency of essential trace elements and excess of toxic trace elements, both of which can affect health. We conducted a systematic review to summarize existing literature on trace element status in hemodialysis patients.</p> <p>Methods</p> <p>All studies which reported relevant data for chronic hemodialysis patients and a healthy control population were eligible, regardless of language or publication status. We included studies which measured at least one of the following elements in whole blood, serum, or plasma: antimony, arsenic, boron, cadmium, chromium, cobalt, copper, fluorine, iodine, lead, manganese, mercury, molybdenum, nickel, selenium, tellurium, thallium, vanadium, and zinc. We calculated differences between hemodialysis patients and controls using the differences in mean trace element level, divided by the pooled standard deviation.</p> <p>Results</p> <p>We identified 128 eligible studies. Available data suggested that levels of cadmium, chromium, copper, lead, and vanadium were higher and that levels of selenium, zinc and manganese were lower in hemodialysis patients, compared with controls. Pooled standard mean differences exceeded 0.8 standard deviation units (a large difference) higher than controls for cadmium, chromium, vanadium, and lower than controls for selenium, zinc, and manganese. No studies reported data on antimony, iodine, tellurium, and thallium concentrations.</p> <p>Conclusion</p> <p>Average blood levels of biologically important trace elements were substantially different in hemodialysis patients, compared with healthy controls. Since both deficiency and excess of trace elements are potentially harmful yet amenable to therapy, the hypothesis that trace element status influences the risk of adverse clinical outcomes is worthy of investigation.</p

A wheat kinase and immune receptor form host-specificity barriers against the blast fungus

Since emerging in Brazil in 1985, wheat blast has spread throughout South America and recently appeared in Bangladesh and Zambia. Here we show that two wheat resistance genes, Rwt3 and Rwt4, acting as host-specificity barriers against non-Triticum blast pathotypes encode a nucleotide-binding leucine-rich repeat immune receptor and a tandem kinase, respectively. Molecular isolation of these genes will enable study of the molecular interaction between pathogen effector and host resistance genes
