Lin and Wang have introduced a quadratic version of the logrank test, appropriate for situations in which the underlying survival distributions may cross. In this note, we generalize the Lin-Wang procedure to incorporate weights and investigate the…

A systematic approach to the successful investigation and management of oliguria uses a reproducible method called the Rules of Three: consideration of three sources of olguria (postrenal, prerenal, and renal), three noninvasive tools for evaluation…

Severe acute respiratory syndrome (SARS) is a newly emerged infection that is caused by a previously unrecognized virus - a novel coronavirus designated as

Abnormalities that increase water reabsorption can lead to hyponatremia, and the resulting water retention presents the threat of CNS volume changes. Avoid overcorrection of hyponatremia, however, as this causes similar changes. Also, be aware of…

Associating microRNAs (miRNAs) with cancers is an important step of understanding the mechanisms of cancer pathogenesis and finding novel biomarkers for cancer therapies. In this study, we constructed a miRNA-cancer association network (miCancerna)…

Previously, alveolar liquid clearance (ALC) was observed to increase in a canine model of neurogenic pulmonary edema (NPE) by adrenal epinephrine (S. M. Lane, K. C. Maender, N. E. Awender, and M. B. Maron. Am. J. Respir. Crit. Care Med. 158:

Objectives: Electronic trigger detection tools hold promise to reduce Adverse drug event (ADEs) through efficiencies of scale and real-time reporting. We hypothesized that such a tool could automatically detect medication dosing errors as well as…

This article demonstrated a systematic approach to acid-base problem solving through the application of the so-called "Rules of Five." This technique was compared with other options for acid-base problem solving, namely, clinicians' use of gestalt or…

Women often express concern about what they consider to be excess body or facial hair. This surplus of hair may be normal or it may signal hypertrichosis or hirsutism. Hirsutism may be idiopathic, secondary to increased responsiveness of hair…

A randomized clinical experiment to compare two types of endotracheal tubes utilized a block design where each of the six participating anesthesiologists performed tube insertions for an equal number of patients for each type of tube. Five…

Survival analysis focuses on modeling and predicting the time to an event of interest. Many statistical models have been proposed for survival analysis. They often impose strong assumptions on hazard functions, which describe how the risk of an event…
