Prediction of myocardial infarction risk in older patients with acute coronary syndrome.

Purposes: To identify bedside variables that aid in diagnosis of acute coronary syndrome (ACS) and might facilitate rapid triage of patients aged > or = 65 years.

Basic Procedures: Prospective, observational study of consecutive patients aged > or = 65 years with suspicion of ACS presenting to our emergency department (ED). Patients' medical characteristics were collected at baseline and during a 1-month follow-up period.

Impact of point-of-care testing in the emergency department evaluation and treatment of patients with suspected acute coronary syndromes.

Objectives: To assess the impact of point-of-care testing (POCT) for troponin I (cTnI) measurement on the time to anti-ischemic therapy (TAIT) for patients with suspected non-ST-segment elevation acute coronary syndrome (NSTE-ACS) presenting to the emergency department (ED).

Methods: This was an open-label, randomized, single-center trial conducted in a university-affiliated hospital. cTnI measurement of patients with suspicion of NSTE-ACS coming to the ED was randomly allocated to POCT or central hospital laboratory testing (CHLT).

A single procalcitonin level does not predict adverse outcomes of women with pyelonephritis.

Objectives: Predicting medical outcomes for pyelonephritis in women is difficult, leading to unnecessary hospitalization. Unlike other serious infectious diseases, high procalcitonin (PCT) level has never been associated with 28-d adverse medical outcomes in women with pyelonephritis. Therefore, we sought to determine the accuracy of PCT in discriminating between pyelonephritis with adverse medical outcome (PAMO) and pyelonephritis without adverse medical outcome (PWAMO).
