Neuroscience and education: prime time to build the bridge

As neuroscience gains social traction and entices media attention, the notion that education has much to benefit from brain research becomes increasingly popular. However, it has been argued that the fundamental bridge toward education is cognitive psychology, not neuroscience. We discuss four specific cases in which neuroscience synergizes with other disciplines to serve education, ranging from very general physiological aspects of human learning such as nutrition, exercise and sleep, to brain architectures that shape the way we acquire language and reading, and neuroscience tools that increasingly allow the early detection of cognitive deficits, especially in preverbal infants. Neuroscience methods, tools and theoretical frameworks have broadened our understanding of the mind in a way that is highly relevant to educational practice. Although the bridge’s cement is still fresh, we argue why it is prime time to march over it

Postoperative urinary tract infection and short-term outcomes and costs in head and neck cancer surgery

OBJECTIVES: Catheter-associated urinary tract infections (UTIs) have been identified as a preventable 'never event' by the Centers for Medicare and Medicaid Services. We sought to determine the relationship between UTI and in-hospital mortality, postoperative complications, length of stay, and costs in head and neck cancer (HNCA) surgery. STUDY DESIGN: Cross-sectional analysis using cross-tabulations and multivariate regression modeling. SETTING: The Nationwide Inpatient Sample database. SUBJECTS AND METHODS: Discharge data for 93,663 patients who underwent an ablative procedure for a malignant oral cavity, laryngeal, hypopharyngeal, or oropharyngeal neoplasm in 2003-2008 were analyzed. RESULTS: Urinary tract infection was diagnosed in 2% of patients, with catheter-associated UTI coded in only 20 patients. Patients with UTI were more likely to be older than 80 years (odds ratio [OR], 3.3; P = .008), be female (OR, 1.9; P < .001), have advanced comorbidity (OR, 1.8; P < .012), undergo major surgical procedures (OR, 1.7; P = .001), and have predisposing bladder and prostate conditions (OR, 3.8; P < .001), surgical complications (OR, 2.3; P < .001), and acute medical complications (OR, 3.1; P < .001). Urinary tract infection was associated with significantly increased length of hospitalization and hospital-related costs, after controlling for all other variables. CONCLUSION: Urinary tract infection is unusual in HNCA surgical patients but is more common with extent of surgery and age and is significantly associated with postoperative complications, length of hospitalization, and hospital-related costs. Catheter-associated UTI is likely underestimated because of difficulty in distinguishing between a catheter-associated UTI and postoperative UTI in patients undergoing major surgical procedures, who routinely undergo perioperative urinary catheterization. Patients with HNCA are a high-risk group for this 'never event,' particularly as the population ages
