Bloodstream infection, venous thrombosis, and peripherally inserted central catheters: reappraising the evidence.
The widespread use of peripherally inserted central catheters (PICCs) has transformed the care of medical and surgical patients. Whereas intravenous antibiotics, parenteral nutrition, and administration of chemotherapy once necessitated prolonged hospitalization, PICCs have eliminated the need for such practice. However, PICCs may not be as innocuous as once thought; a growing body of evidence suggests that these devices also have important risks. ⋯ In this context, we introduce a conceptual model to understand the risk of PICC-related complications and guide the use of these devices. Through this model, we outline recommendations that clinicians may use to prevent PICC-related adverse events. We conclude by highlighting important knowledge gaps and identifying avenues for future research in this area.

Vascular disease (including myocardial infarction and peripheral artery disease) has been proposed as a less well-validated risk factor for stroke in patients with atrial fibrillation. We investigated whether vascular disease is an independent risk factor of stroke/thromboembolism in atrial fibrillation and whether adding vascular disease improves Congestive heart failure, Hypertension, Age 75 years, Diabetes, previous Stroke (CHADS(2)) risk stratification. ⋯ Vascular disease is an independent predictor of stroke/thromboembolism in atrial fibrillation and improves the predictive ability of the CHADS(2) score.

The National Academies reported in Beyond Bias and Barriers: Fulfilling the Potential of Women in Academic Science and Engineering (2006) that "women are very likely to face discrimination." In academic medicine, gender distribution is becoming more balanced. In the federal government, women also have made progress, doubling their representation in professional positions to 44%. The Department of Veterans Affairs (VA) has a research program and a mission to train health care professionals; however, its gender distribution has not been described. ⋯ Marked gender disparities were seen in the VA, except in Health Services Research. Organizations must investigate their practices to reveal disparities, investigate underlying factors, and intervene as needed.

Previous research on the management of hyperglycemia in patients with sepsis has focused primarily on those with established organ failure in the critical care setting. The impact of hyperglycemia and glycemic control in patients with infection before developing severe sepsis or shock remains undefined. ⋯ In this cohort of acutely infected patients without established severe sepsis or shock, higher glucose concentrations within the first 72 hours in the nondiabetic population were associated with worse hospital outcomes and were less likely to be treated with insulin compared with diabetic patients.

We hypothesized that women with early- and mid-adult life obesity, as well as high mid-adult life waist-to-hip ratios, and high weight gain during adulthood, experience a greater incidence of gout. ⋯ In a large cohort of black and white women, obesity in early- and mid-adulthood, and weight gain during this interval, were each independent risk factors for incident gout in women.
