OBJECTIVE The purposes of this study were to describe and compare the prevalence of disease features in subjects with Mycobacterium avium complex (MAC) disease with those of Mycobacterium tuberculosis infection (MTB), to compare the abilities of CT and chest radiography to identify the features of MAC disease, and to determine if sputum positivity is(More)
Although completely eliminating the risk for transmission of M. tuberculosis in all health-care facilities may not be possible, adherence to the principles outlined in the CDC guidelines should reduce the risk to persons in such settings. The guidelines are designed to help health-care facilities develop an infection-control plan tailored to the individual(More)
SETTING The highest priority for tuberculosis (TB) control is to ensure patients complete therapy. However, standardized, detailed evaluation of national performance on completion of therapy in the United States has been lacking. Since 1982, the Centers for Disease Control and Prevention (CDC) has had a program objective that at least 90% of TB cases(More)
BACKGROUND To eliminate tuberculosis (TB) in the United States, more information is needed on how to gain access to difficult-to-reach, high-risk populations to evaluate people who would benefit from treatment for latent TB infection (LTBI). METHODS A field study was conducted of people at risk for co-infection with TB and the human immunodeficiency virus(More)
Organization (WHO) epidemiologist stationed in Vietnam, alerted the global health community to the high transmissibility and lethality associated with an apparently new respiratory disease. This disease, now called severe acute respiratory syndrome (SARS), is believed to have emerged in China in November 2002 and progressed to a global health threat by the(More)
Aminoglycoside use is limited by ototoxicity and nephrotoxicity. This study compared the incidences of toxicities associated with 2 recommended dosing regimens. Eighty-seven patients with tuberculosis or nontuberculous mycobacterial infections were prospectively randomized by drug to receive 15 mg/kg per day or 25 mg/kg 3 times per week of intravenous(More)
After years of steady decline, there has been an unprecedented resurgence of tuberculosis (TB) in the United States and outbreaks of multidrug-resistant tuberculosis (MDR-TB). The authors assess the nature, epidemiology, and implications of MDR-TB; provide suggestions for preventing drug resistance among patients with drug-susceptible TB; and offer(More)
This study examined the ability of young adults, older adults, and older adults suffering from Alzheimer's disease (AD) to perform a selective reaching task. Normal aging did not increase interference caused by distractors. In contrast, patients with AD showed massively increased effects of distractor interference. AD patients showed a high probability of(More)
Memory and attention are interrelated cognitive processes that most likely influence the functioning of each other, yet they are often difficult to distinguish in psychological experiments. Young, aged adults, and patients with Alzheimer disease (AD) were tested on a delay response task measuring spatial memory that also placed high demands on attentional(More)
