Objective: It is known that regular exercise improves both physical and mental health. This study sought to determine the impact of a fitness intervention on the levels of exercise and well-being of medical students. Methods: In 2011, the authors conducted a prospective cohort study involving medical students at the Johns…
More than 1 million people in the United States have Parkinson disease (PD), more than are diagnosed as having multiple sclerosis, amyotrophic lateral sclerosis, muscular dystrophy, and myasthenia gravis combined. PD affects approximately 1 in 100 Americans older than 60 years. It burdens patients, their care partners, and the overall…
In 1817, James Parkinson published the essay “Shaking Palsy,” in which he described patients with “involuntary tremulous motion” and “a propensity to bend the trunk forward and to pass from a walking to a running pace.”1 The disorder was further characterized by Jean-Martin Charcot in 1872, who first referred to…
Evidence suggests prognostic utility of troponin (Tn) serum concentrations for a variety of conditions. We sought to determine whether elevated concentrations early after anthracycline chemotherapy predict the development of left ventricular systolic dysfunction in adult patients with cancer. PubMed/MEDLINE searches identified original reports that assessed cardiac TnI or TnT within…
The objectives of this article were to review the anabolic androgen steroids, specifically the direct and indirect effects on the cardiovascular system of the individuals who use them, and to summarize the evidence regarding the effects of androgens on the cardiovascular system. A search of the English-language scientific literature from…
To the EditorWe read with great interest the Anchondo et al article published in the May 2012 issue of the Southern Medical Journal, in which the authors report the results of an institutional survey of pediatricians, obstetricians, gynecologists, and family medicine physicians.1 In this study, the physicians reported minimal breast-feeding…
To the EditorWe thank Sattari and colleagues for their thoughtful letter. In their study,1 physician mothers reported high breast-feeding rates, yet the authors recognized the possibility that the interview method, a researcher-administered questionnaire, may have discouraged unsuccessful breast-feeders and encouraged successful breast-feeders to participate. We agree with this conclusion and…
In the commentary that appeared on page 581 of the November 2012 issue, Dr Kaissi’s given name was misspelled. The correct spelling is Amer.
Objective: The diagnosis of mediastinal and hilar lymphadenopathy and staging lung cancer with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) are on the rise. Most reports have demonstrated high yields with EBUS-TBNA and superiority of this procedure over conventional TBNA (cTBNA), but the relative roles of these procedures remain undefined. We…
In the United States, adequate attention has not been given to emphasizing public health and preventive medicine in undergraduate medical education, despite well-meaning efforts on the part of some dedicated individuals. Although most medical schools recognize the importance of exposure to these fundamental elements of clinical care of the population…
Objective: To assess the trends for smoking during pregnancy for whites and blacks in Missouri, a state with a high prevalence of smoking, for the period 1990–2009. Methods: Retrospective cohort study of annual pregnancy smoking rates recorded on birth certificates. Trends were assessed by regression analyses for all births, births…
Objectives: Endobronchial ultrasound (EBUS)-transbronchial needle aspiration (TBNA) is a relatively noninvasive technique that allows sampling of mediastinal and hilar lymph nodes or masses under real-time and direct visualization, overcoming some of the problems associated with mediastinoscopy and blind TBNA. The goal of this study was to evaluate the yield of…
For years, the pharmaceutical industry has been trying to find a safe and effective drug to replace warfarin. Although warfarin is an effective anticoagulant, its pharmacology, adverse effects, and risk profiles dictate that patients taking this medication must be monitored judiciously. The US Food and Drug Administration has approved two…
To the EditorThe pretest probability of solitary pulmonary nodule (SPN) malignancy is estimated either qualitatively by using clinical judgment through initial history, physical examination, assessment of risk factors, careful evaluation of the chest radiography, and computed tomography (CT) scan, or quantitatively by using the assistance of quantitative models.1 Lesions are…
