BACKGROUND: Multiorgan ultrasound (US), which includes evaluation of the lungs and heart, is an accurate method that outperforms clinical gestalt for diagnosing acutely decompensated heart failure (ADHF). A known barrier to ultrasound use is the time needed to perform these examinations. OBJECTIVE: The primary goal of this study was to determine the test characteristics of a modified lung and cardiac US (LuCUS) protocol for the accurate diagnosis of ADHF. METHODS: This was a secondary analysis of a prospective observational study that enrolled adult patients presenting to the emergency department with undifferentiated dyspnea...

INTRODUCTION AND OBJECTIVES: The association between Streptococcus bovis group infective endocarditis and colorectal neoplasm (CRN) is well-known. However, no studies have assessed the association between Enterococcus faecalis infective endocarditis (EFIE) and CRN. We aimed to determine whether the prevalence of CRN is higher in patients with EFIE and an unclear source of infection than in patients with EFIE and a known source of infection or in the general population. METHODS: Retrospective analysis of a cohort of 154 patients with definite EFIE (109 with an unclear source of infection and 45 with an identified source) from 2 Spanish teaching hospitals to determine the prevalence of CRN and other colorectal diseases...

As a reagent gas for positive- and negative-mode chemical ionization mass spectrometry (CI-MS), isobutane (i-C4H10) produces superior analyte signal abundance to methane. Isobutane has never been widely adopted for CI-MS because it fouls the ion source more rapidly and produces positive CI spectra that are more strongly dependent on reagent gas pressure compared with methane. Isobutane was diluted to various concentrations in argon for use as a reagent gas with an unmodified commercial gas chromatograph-mass spectrometer...

Hexamethylene triperoxide diamine (HMTD) is an easily synthesized and highly sensitive organic peroxide frequently used as a primary explosive. The vapor pressure of HMTD is very low, impeding vapor detection, especially when compared to other peroxide explosives, such as triacetone triperoxide (TATP) or diacetone diperoxide (DADP). Despite this fact, HMTD has a perceptible odor that could be utilized in the indirect detection of HMTD vapor. Headspace measurements above solid HMTD samples confirm that HMTD readily decomposes under ambient conditions to form highly volatile products that include formic acid, ammonia, trimethylamine and formamides...

OBJECTIVES: The primary goal of this study was to determine accuracy for diagnosing acutely decompensated heart failure (ADHF) in the undifferentiated dyspneic emergency department (ED) patient using a lung and cardiac ultrasound (LuCUS) protocol. Secondary objectives were to determine if US findings acutely change management and if findings are more accurate than clinical gestalt. METHODS: This was a prospective, observational study of adult patients presenting to the ED with undifferentiated dyspnea...

Polyreactive autoantibodies able to bind double-stranded DNA are a characteristic of systemic lucus erytheamtosus. Here, David Isenberg and Yehuda Shoenfeld discuss the likelihood that DNA is the immunogen in this disorder, and review a number of cross-reactions that may underline the detection of the antibodies.

Having shown that Lucus Augusti Hospital in Lugo, Spain, has been affected by Escherichia coli clone O25:H4-ST131 producing CTX-M-15, the present study was carried out to evaluate the prevalence of this clone among the extended-spectrum β-lactamase (ESBL)-producing E. coli isolates and to identify novel variants of this clone. Of the 77 ESBL-producing E. coli isolated between January and April 2012, 47 (61%) were identified as belonging to the ST131 clonal group, comprising 38 O25b:H4-B2-ST131 (34 CTX-M-15, 2 CTX-M-14, 1 CTX-M-1 and 1 CTX-M-27), 7 O-non-typeable:H4-B2-ST131 (all CTX-M-15) and 2 O16:H5-B2-ST131 (both CTX-M-14)...

OBJECTIVE: To determine if an association exists between daily physical activity, and pregnancy/neonatal outcomes in stay at home military wives. METHODS: This is a prospective observational study of pregnant military wives who do not work outside the home. Participants completed a validated questionnaire of their daily activity from which the average energy expenditure per day (kcal/day) was calculated. Participants were grouped, according to their energy expenditure and assessed for antepartum, intrapartum, and neonatal outcomes...

Vegetarians are at risk for vitamin B(12) (B12) deficiency due to suboptimal intake. The goal of the present literature review was to assess the rate of B12 depletion and deficiency among vegetarians and vegans. Using a PubMed search to identify relevant publications, 18 articles were found that reported B12 deficiency rates from studies that identified deficiency by measuring methylmalonic acid, holo-transcobalamin II, or both. The deficiency rates reported for specific populations were as follows: 62% among pregnant women, between 25% and almost 86% among children, 21-41% among adolescents, and 11-90% among the elderly...

Chronic pain is a complex problem that eludes precise definition and can be clinically difficult to diagnose and challenging to treat. In the Asia-Pacific region, prevalence estimates that chronic pain ranges from 12% to 45% of the population, with musculoskeletal, rheumatic or osteoarthritis pain making up the majority of the disease burden. Implementation of current management guidelines into routine clinical practice has been challenging and as a result, patients with musculoskeletal pain are often poorly managed...

BACKGROUND AND OBJECTIVE: Despite numerous body moisturizers being available, cosmetic xerosis continues to be a leading skin problem for consumers. We performed two 35-day studies to evaluate the ability of a variety of body moisturizers containing various levels of oils/lipids, humectants, as well as other ingredients (e.g., niacinamide) to improve stratum corneum integrity. METHODS: 63 and 58 female subjects were enrolled and randomized in an incomplete block design to six of nine products (eight moisturizers or no treatment control) in studies 1 and 2, respectively...

BACKGROUND: With the advent of holo-body computed tomography scanning of trauma patients, the radiologic diagnosis of transverse process fractures (TPF) has increased. The significance of this fracture has not been elucidated. Spine service (neurosurgical or orthopedic) consultation is frequently requested for patients with these fractures, stressing constraints on these practices. We hypothesize that isolated transverse process fractures (iTPF) are structurally and neurologically stable injuries, which do not require spine service intervention...

BACKGROUND: Several clinical trials have shown that intensive lifestyle modification programs have a significant impact on cardiovascular risk factors. HYPOTHESIS: This paper is a retrospective analysis to determine the effect of participation in a 2-year lifestyle management program on long-term clinical outcome in patients outside the setting of a clinical trial. METHODS: Patients with angiographically confirmed coronary artery disease (CAD) enrolled in a 2-year program of exercise training, dietary counseling, stress management, and therapeutic education...

Hyperbaric oxygen (HBO) therapy has been used to treat patients with numerous disorders, including stroke. This treatment has been shown to decrease cerebral edema, normalize water content in the brain, decrease the severity of brain infarction, and maintain blood-brain barrier integrity. In addition, HBO therapy attenuates motor deficits, decreases the risks of sequelae, and prevents recurrent cerebral circulatory disorders, thereby leading to improved outcomes and survival. Hyperbaric oxygen also accelerates the regression of atherosclerotic lesions, promotes antioxidant defenses, and suppresses the proliferation of macrophages and foam cells in atherosclerotic lesions...

Allelic frequencies of chromosome micro-satellite locuses D16S539, F13B, FESFPS, TH01 and TPOX were determined, within the case study, in a sampling of Europeoidal individuals residing in Russia's Ural Region. The allelic variants were analyzed by capillary electrophoresis after the enzyme amplification in polymerase chain reaction with fluorescent primers. The genotypic frequencies of the studied locuses were shown not to divert with statistical reliability from Hardy-Weinberg equilibrium. The estimated aggregate discriminative potential for a panel of 5 studied locuses made 0...
