Our study showed that an average of 10 days of warfarin prophylaxis given in the hospital only provided safe and effective patient care. With current lengths of hospital stay after joint arthroplasty as short as 4 days, the question is raised about whether outpatient warfarin treatment is warranted to ensure that patients receive prophylaxis for at least 10 days.Our study does shed some light on this matter.

Abstract 2961: Ventricular Stiffness Contributes to Hypertension in Patients with Clinical Science Repaired Coarctation of the Aorta
Authors: Hideaki Senzaki, Hirotaka Ishido, Satoshi Masutani
Journal: Circulation (2007)

Background Despite successful repair, patients with coarctation of the aorta (CoA) often show persistent hypertension at rest and/or during exercise. Previous studies indicated that this phenomenon is mainly due to abnormality in arterial bed and its regulatory system. However, blood pressure is determined not only by the state of arterial bed but also by cardiac function to which the blood vessels are coupled. We hypothesized that ventricular stiffness contributes to the hypertensive state in patients with repaired CoA, in addition to increased vascular stiffness. Methods and Results The left ventricular pressure-area relationship was measured invasively in 37 patients (2–14 years of age) with successfully repaired CoA (defined as 0 mmHg pressure gradient) and compared with that of 41 age-matched control subjects who had small ventricular septal defect with an estimated shunt ratio &lt;5%. Data recorded at rest and during transient preload reduction by inferior vena caval obstruction yielded left ventricular chamber stiffness (Ees) and effective arterial stiffness (Ea). The mean systolic blood pressure (SBP) was significantly higher in CoA patients (118±24 mmHg) than in the control (98±9 mmHg, p&lt;0.01). Ees (45±19 mmHg/mlm 2 ) and Ea (36±19 mmHg/mlm 2 ) of CoA patients were significantly higher than those of the controls (18±7 and 20±7 mmHg/mlm 2 , respectively, P&lt;0.001). To quantify the contribution of increased ventricular stiffness to the high SBP in CoA patients, SBP was estimated by assuming that Ees of CoA patients was equal to the mean Ees value of the control. The results showed a significant decrease in blood pressure by 12±5 mmHg, indicating that ventricular stiffness accounts for about 60% of the elevated blood pressure in CoA patients. Conclusions Increased ventricular stiffness greatly contributes to elevated systolic pressure in patients with repaired CoA. Thus, in addition to the recognized arterial stiffness, abnormal neurohumoral activity and autonomic dysfunction, ventricular stiffness could be a viable target for reduction of blood pressure and improvement of prognosis of patients with this disease.
Physical Activity Trends--United States, 1990-1998
Journal: JAMA (2001)

Physical activity is associated with numerous health benefits, and increased participation in various types of leisure-time physical activity had been encouraged during the 1990s. To determine national estimates of leisure-time physical activity during 1990-1998, data were obtained from the Behavioral Risk Factor Surveillance System (BRFSS). This report summarizes the results of that analysis, which indicate that leisure-time physical activity trends have remained unchanged.

Ephedrine therapy in asthmatic children. Clinical tolerance and absence of side effects
Authors: D. G. Tinkelman
Journal: JAMA (1977)

Sixteen asthmatic children between the ages of 7 and 13 years, 13 of whom were receiving theophylline orally around-the-clock, were studied for eight weeks in a double-blind manner to evaluate efficacy, toxicity, and development of tolerance to the combination of ephedrine sulfate and theophylline. Reactions to the drug combination, assessed by close observation and daily patient questioning by the nursing staff, showed no toxicity or substantial side effects. Pulmonary function was measured hourly for six hours after each morning dose, and the data were analyzed to determine the degree and duration of bronchodilator response. Comparison of data from weeks 1 and 8 showed no evidence of the development of tolerance. Ephedrine is a potent bronchodilator that, in appropriate doses, can be administered safely along with therapeutic doses of theophylline without fear of progressive tolerance or toxicity.

Poultry Consumption and Arsenic Exposure in the U.S. Population
Authors: Anne E. Nigra, Keeve E. Nachman, David C. Love, Maria Grau-Perez, Ana Navas-Acien
Journal: Environmental Health Perspectives (2016)

Background:Arsenicals (roxarsone and nitarsone) used in poultry production likely increase inorganic arsenic (iAs), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), and roxarsone or nitarsone concentrations in poultry meat. However, the association between poultry intake and exposure to these arsenic species, as reflected in elevated urinary arsenic concentrations, is unknown.Objectives:Our aim was to evaluate the association between 24-hr dietary recall of poultry consumption and arsenic exposure in the U.S. population. We hypothesized first, that poultry intake would be associated with higher urine arsenic concentrations and second, that the association between turkey intake and increased urine arsenic concentrations would be modified by season, reflecting seasonal use of nitarsone.Methods:We evaluated 3,329 participants ≥ 6 years old from the 2003–2010 National Health and Nutrition Examination Survey (NHANES) with urine arsenic available and undetectable urine arsenobetaine levels. Geometric mean ratios (GMR) of urine total arsenic and DMA were compared across increasing levels of poultry intake.Results:After adjustment, participants in the highest quartile of poultry consumption had urine total arsenic 1.12 (95% CI: 1.04, 1.22) and DMA 1.13 (95% CI: 1.06, 1.20) times higher than nonconsumers. During the fall/winter, participants in the highest quartile of turkey intake had urine total arsenic and DMA 1.17 (95% CI: 0.99, 1.39; p-trend = 0.02) and 1.13 (95% CI: 0.99, 1.30; p-trend = 0.03) times higher, respectively, than nonconsumers. Consumption of turkey during the past 24 hr was not associated with total arsenic or DMA during the spring/summer.Conclusions:Poultry intake was associated with increased urine total arsenic and DMA in NHANES 2003–2010, reflecting arsenic exposure. Seasonally stratified analyses by poultry type provide strong suggestive evidence that the historical use of arsenic-based poultry drugs contributed to arsenic exposure in the U.S. population.Citation:Nigra AE, Nachman KE, Love DC, Grau-Perez M, Navas-Acien A. 2017.

Newer Concepts in Hypertrophic Obstructive Cardiomyopathy I
Authors: Pravin M. Shah
Journal: JAMA (1979)

HYPERTROPHIC obstructive cardiomyopathy is a form of primary myocardial disease with a characteristic clinical and pathological expression. The disorder is referred to by several names. Braunwald and associates<sup>1</sup>introduced and popularized the term "idiopathic hypertrophic subaortic stenosis" in the United States, Wigle and associates<sup>2</sup>coined the term "muscular subaortic stenosis" in Canada, while in Europe it is generally referred to as hypertrophic obstructive cardiomyopathy (HOCM), following the lead of Goodwin and associates<sup>3</sup>at the Royal Postgraduate School of Medicine in London. A term that includes subaortic stenosis is unfortunate, since the disorder may be expressed without left ventricular outflow obstruction and since patients have been described as having isolated infundibular subpulmonic stenosis. It is more accurate and potentially less confusing to refer to the disorder as hypertrophic cardiomyopathy and add the word "obstructive" if either left or right ventricular outflow obstruction can be demonstrated.<sup>4</sup>The historical aspects of

Back Pain: The History and Physical Examination
Authors: Alan M. Abromovitz
Journal: JAMA (1993)

<h3>To the Editor.</h3> —I read with great interest the recent article in<i>JAMA</i>regarding the rational clinical examination of lower back pain.<sup>1</sup>In the introductory remarks, numerous apparent causes of lower back pain were described, and the article goes on to discuss the serious causes of disease that create pain in the lower back. It is not surprising to read that up to 85% of patients cannot be given a definitive diagnosis using the criteria of the article and the diagnostic techniques. The authors make no mention of palpatory physical examination and motion testing to evaluate structural symmetry, limitations in normal joint motion in the facet joints, sacroiliac joints, and pubic symphysis articulation. I assume this is because the authors have never been trained to perform an adequate biomechanical and structural evaluation of the musculoskeletal system, and do not have the skills to localize and determine the cause of
Hypertension screening of 1 million Americans. Community Hypertension Evaluation Clinic (CHEC) program, 1973 through 1975
Authors: J. Stamler
Journal: JAMA (1976)

During 1973 through 1975, more than 1 million persons were screened in the nationwide Community Hypertension Evaluation Clinic (CHEC) program at 1,171 sites. While those screened were not from defined populations, findings paralleled those of recent surveys of US population samples. First, CHEC confirmed the scope of the problem of elevated blood pressure in the United States. Of those screened, 247 of 1,000 had a diastolic reading of 90 mm Hg or higher; 116 of 1,000 had a reading of 95 mm Hg or greater. Prevalence of elevated blood pressure rose with age up to age 50 years, was higher in blacks than in whites, and was higher in men than in women. Second, CHEC data confirmed the challenge of undetected, untreated, and uncontrolled hypertension. Previously undetected hypertension was present in 27.7% of hypertensive people, detected but untreated in 10.7%, and treated but uncontrolled in 16.7%—totaling 55.1%. (<i>JAMA</i>235:2299-2306, 1976)
