The association between a prior diagnosis of diabetes mellitus and cancer was examined in a large multisite case-control study based on interviews of 8220 white males and 6690 white females aged 30-89 who were admitted to Roswell Park Memorial Institute between 1957 and 1965 for the diagnosis and treatment of cancer. A prior history of diabetes mellitus as(More)
OBJECTIVE The objective of the study was to assess the success rate of emergency department (ED) technicians in placing ultrasound (US)-guided peripheral intravenous (i.v.) catheters. METHODS In this prospective, observational trial, 19 ED technicians were taught to use US guidance to obtain i.v. access. Training sessions consisted of didactic instruction(More)
STUDY OBJECTIVE We examine the central venous catheter placement rate during the implementation of an ultrasound-guided peripheral intravenous access program. METHODS We conducted a time-series analysis of the monthly central venous catheter rate among adult emergency department (ED) patients in an academic urban ED between 2006 and 2011. During this(More)
BACKGROUND Major gaps persist in the development, validation, and implementation of clinical decision rules (CDRs) for diagnostic imaging. OBJECTIVES The objective of this working group and article was to generate a consensus-based research agenda for the development and implementation of CDRs for diagnostic imaging in the emergency department (ED).

Leptin is a protein encoded by the ob gene and expressed in adipocytes. A sensitive marker of nutritional status, leptin is known to correlate with fat mass and to respond to changes in caloric intake. Leptin may also be an important mediator of reproductive function, as suggested by the effects of leptin infusions to restore ovulatory function in an animal(More)
BACKGROUND Shared decision making (SDM) is increasingly recognized as an important facet of patient-centered care. Despite growing interest in SDM in the emergency department (ED), little is known about emergency physicians' (EPs') motivations for using SDM. Understanding current patterns of SDM use and EP's rationale for using SDM is essential for the(More)
BACKGROUND Post-partum mastitis is a common infection in breastfeeding women, with an incidence of 9.5-16% in recent literature. Over the past decade, community-acquired methicillin-resistant Staphylococcus aureus (MRSA) has emerged as a significant pathogen in soft-tissue infections presenting to the emergency department. The incidence of mastitis caused(More)
BACKGROUND Evidence suggests that periodontitis is associated with prevalent and incident type 2 diabetes mellitus (T2DM), raising the question of whether periodontitis treatment may improve glycemic control in patients with T2DM. Meta-analyses of mostly small clinical trials suggest that periodontitis treatment results in a modest reduction in glycosylated(More)
INTRODUCTION To assess characteristics, satisfaction, and disposition of emergency department (ED) patients who successfully received ultrasound (US)-guided peripheral intravenous (IV) access. METHODS This is a prospective observational study among ED patients who successfully received US-guided peripheral IV access by ED technicians. Nineteen ED(More)
INTRODUCTION In the United States there is debate regarding the appropriate first test for new-onset renal colic, with non-contrast helical computed tomography (CT) receiving the highest ratings from both Agency for Healthcare Research and Quality and the American Urological Association. This is based not only on its accuracy for the diagnosis of renal(More)
