BACKGROUND Although the prognostic power of heart rate variability (HRV) at rest has been demonstrated, the prognostic potential of exercise-induced HRV has not been investigated. We aimed to evaluate the prognostic power of exercise-induced HRV during and after standard exercise testing. METHODS Time- and frequency-domain HRV analysis was performed on(More)
A study of primary epithelial neoplasms of the appendix (with the exception of classical carcinoids), produced 24 adenocarcinomas and 42 benign lesions from the files of the Laboratory of Surgical Pathology of Columbia University. Invasive adenoarcinomas were often complicated by appendicitis and were then unexpectedly discovered during appendectomy. In one(More)

We hypothesize that the use of oral antibiotics in bowel preparation results in a higher rate of postoperative Clostridium difficile colitis. DESIGN Retrospective case-controlled study of elective colon surgery patients; January 1997 to June(More)
Forty-two cases of benign epithelial neoplasms of the appendix gleaned from the files of the Laboratory of Surgical Pathology, Columbia University, were studied. The majority were associated with dilatation of the appendix, or "mucocele." Conversely only 50% of all cystically dilated appendices examined had definite underlying adenomatous changes. Thus it(More)

Yet a resistance to the inclusion of human rights in the medical ethics and law curriculum persists. In response to Stirrat and colleagues, this article seeks to highlight the mutual(More)

In men aged 35-64 it is 200 times as common in the Gurjev District of Kazakhstan as in parts of Canada, Holland and Nigeria, whereas for the same age group the worldwide range of frequency for cancer of the lung is only fortyfold and(More)
