BACKGROUND Identification of patients vulnerable for atrial fibrillation (AF) after major thoracic surgery will allow targeting those most likely to benefit from prophylactic therapy. The goal of the current study was to evaluate the accuracy of easily available clinical characteristics for the prediction of this complication. METHODS Patients undergoing(More)
BACKGROUND Supraventricular tachydysrhythmias (SVTs) following thoracic surgery occur with significant frequency and may be associated with increased morbidity. Prospective data on the etiology and importance of these dysrhythmias are sparse. METHODS In 100 patients undergoing pulmonary resection without history of atrial dysrhythmias or previous thoracic(More)
OBJECTIVES We sought to determine whether early prophylaxis with an L -type calcium channel blocker reduces the incidence and morbidity associated with atrial fibrillation/flutter and supraventricular tachyarrhythmia after major thoracic operations. METHODS In this randomized, double-blind, placebo-controlled study, 330 patients were given either(More)

Anthropologists have long noted that one of the primary functions of religion is to promote group solidarity, and most have recognized ritual as the mechanism through which this solidarity is achieved. Guided by Durkheim (1995 [1912]), who was among the first to appreciate the unifying nature of religious ritual, functionalists have explored how ritual(More)
The in-group-out-group bias is among the most well documented and widely observed phenomenon in the social sciences. Despite its role in hiring decisions and job discrimination, negotiations, and conflict and competition between groups, economists have heretofore ignored the in-group-out-group bias. We question the universality of the bias by designing(More)
Comparing the gene-expression profiles of sick and healthy individuals can help in understanding disease. Such differential expression analysis is a well-established way to find gene sets whose expression is altered in the disease. Recent approaches to gene-expression analysis go a step further and seek differential co-expression patterns, wherein the level(More)
BACKGROUND This prospective study was designed to determine whether diltiazem is superior to digoxin for the prophylaxis of supraventricular dysrhythmias (SVD) after pneumonectomy or extrapleural pneumonectomy (EPP) and to assess the influence of these drugs on perioperative cardiac function. METHODS Seventy consecutive patients without previous SVD were(More)
OBJECTIVES Postoperative atrial fibrillation (POAF) complicating general thoracic surgery is a marker of increased morbidity and stroke risk. Our goal was to determine whether increased preoperative brain natriuretic peptide (BNP) levels are able to stratify patients by the risk of POAF. METHODS Using a prospective database of 415 patients aged 60 years(More)
BACKGROUND Lung injury, defined as acute hypoxemia accompanied by radiographic pulmonary infiltrates without a clearly identifiable cause, is a major cause of morbidity and mortality after major anatomic pulmonary resection. Our objective was to identify the incidence and risk factors for the development of postoperative lung injury. METHODS A(More)
OBJECTIVES This study was designed to evaluate autonomic changes preceding atrial fibrillation/flutter (AF) after thoracotomy. BACKGROUND Autonomic fluctuations before the onset of postoperative AF have been reported but with conflicting results. METHODS In 48 patients with postoperative AF, 2-h Holter recordings before the onset of AF were compared(More)
