PURPOSE: Evidence to date on the unique female determinants of cardiovascular risk is inadequate. Positron Emission Tomography (PET) is considered to have the highest accuracy for the assessment of myocardial perfusion in patients with suspected coronary artery disease (CAD), but its long-term prognostic accuracy in women has not been established. METHODS: A total of 619 consecutive patients (138 women, mean age 60.0 ± 11.8 years) underwent clinically indicated 13 N-ammonia PET at our institution and were followed up (median 5...

FDA regulations require safety testing of constituent ingredients in drugs (21 CFR 610.15). With the exception of extraneous proteins, no component safety testing is required for vaccines or vaccine schedules. The dosing of aluminum in vaccines is based on the production of antibody titers, not safety science. Here we estimate a Pediatric Dose Limit that considers body weight. We identify several serious historical missteps in past analyses of provisional safe levels of aluminum in vaccines, and provide updates relevant to infant aluminum exposure in the pediatric schedule considering pediatric body weight...

On October 6, 2017, an outbreak of cholera was declared in Zambia after laboratory confirmation of Vibrio cholerae O1, biotype El Tor, serotype Ogawa, from stool specimens from two patients with acute watery diarrhea. The two patients had gone to a clinic in Lusaka, the capital city, on October 4. Cholera cases increased rapidly, from several hundred cases in early December 2017 to approximately 2,000 by early January 2018 (Figure). In collaboration with partners, the Zambia Ministry of Health (MoH) launched a multifaceted public health response that included increased chlorination of the Lusaka municipal water supply, provision of emergency water supplies, water quality monitoring and testing, enhanced surveillance, epidemiologic investigations, a cholera vaccination campaign, aggressive case management and health care worker training, and laboratory testing of clinical samples...

Renal denervation (RDN) is a potential modality in the treatment of patients with resistant hypertension (RH) and has shown beneficial effect on a variety of cardiovascular surrogate markers. Coronary flow reserve, as assessed by transthoracic Doppler echocardiography (TDE-CFR) is impaired in patients with hypertension and is an independent predictor of cardiac morbidity. However, data on the effect of RDN on TDE-CFR are scarce. The main objective of this study was to assess the effect of RDN on TDE-CFR. Twenty-six consecutive patients with RH (9 female and 17 male; mean age 62 ± 8 years; mean number of antihypertensive drugs 4·2 ± 1·6) underwent bilateral RDN...

Background: Early clinical severity assessments during the 2009 influenza A H1N1 pandemic (pH1N1) overestimated clinical severity due to selection bias and other factors. We retrospectively investigated how to use data from the International Network for Strategic Initiatives in Global HIV Trials, a global clinical influenza research network, to make more accurate case fatality ratio (CFR) estimates early in a future pandemic, an essential part of pandemic response. Methods: We estimated the CFR of medically attended influenza (CFRMA) as the product of probability of hospitalization given confirmed outpatient influenza and the probability of death given hospitalization with confirmed influenza for the pandemic (2009-2011) and post-pandemic (2012-2015) periods...

Coronary flow reserve (CFR), a measure of both obstructive coronary artery disease and microvascular dysfunction, has been evaluated in systemic rheumatic diseases (RDs), but a comprehensive critical appraisal of the available evidence is lacking. The objective of this study is to conduct a systematic review and meta-analysis of studies with small sample size investigating the associations between the presence of RDs and CFR to increase statistical power and accuracy. PubMed, Web of Science, Scopus, and Google Scholar, from inception to March 2018, were searched for studies reporting on CFR in RDs in comparison to healthy subjects...

Monascus purpureus is known to produce several coloured secondary metabolites. In this study, M. purpureus CFR 410-11 mutant fermented with rice was dried and extracted in hexane for purification of pigment. The purity of the isolated pigment was confirmed by different chromatography techniques. The spectroscopic analysis revealed its structural identity as rubropunctatin. The antioxidant potencies of isolated rubropunctatin were evaluated. Rubropunctatin scavenged 16% 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical and inhibited 20% superoxide generation at 8 μg/ml concentration...

INTRODUCTION: Successful treatment of haematological malignancies is frequently complicated by invasive aspergillosis (IA), a life-threatening fungal infection that occurs in at least 10% of haematooncological patients. Case fatality rates (CFR) may fluctuate over time, depending on host pathogen interactions as well as on treatment and quality of patient care. We conducted a systematic review and metaanalysis of current - i.e. 2008-revised EORTC-MSG criteria era - incidence and case fatality rates (CFR) of IA in patients with haematological malignancy...

BACKGROUND: In patients with angina undergoing invasive management, no obstructive coronary artery disease (NOCAD) is a common finding, and angina may persist following percutaneous coronary intervention (PCI). Coronary microvascular dysfunction may be relevant. We aimed to assess the proportion of patients presenting with suspected CAD who had coronary microvascular dysfunction. METHODS: Clinical Evaluation of Magnetic Resonance Imaging in Coronary Heart Disease 2 (CE-MARC 2) was a prospective multicenter randomised controlled trial of functional imaging versus guideline-based management in patients with suspected CAD...

AIM: U.S. federal regulations for research involving exception from informed consent (EFIC) include stipulations for community consultation (CC) and public disclosure (PD) (FDA 21 CFR 50.24). Published descriptions of PD campaigns include letters to community leaders, media outreach, paid advertising, and community meetings. Whether or not these activities provide measurable impact is unknown, as few prior works have evaluated PD activities with probabilistic polling. The aim of this study is to use polling to assess how much public awareness PD efforts generate...

The epidemiology of invasive meningococcal disease (IMD) is constantly changing as new strains are introduced into a population and older strains are removed through vaccination, population immunity or natural trends. Consequently, the clinical disease associated with circulating strains may also change over time. In England, IMD incidence has declined from 1.8/100,000 in 2010/2011 to 1.1/100,000 in 2013/2014, with a small increase in 2014/2015 to 1.3/100,000. Between 01 January 2011 and 30 June 2015, MenB was responsible for 73...

The relationship between the explosion inerting effectiveness of rock dusts on coal dusts, as a function of the specific surface area (cm2 /g) of each component is examined through the use of 20-L explosion chamber testing. More specifically, a linear relationship is demonstrated for the rock dust to coal dust (or incombustible to combustible) content of such inerted mixtures with the specific surface area of the coal and the inverse of that area of the rock dust. Hence, the inerting effectiveness, defined as above, is more generally linearly dependent on the ratio of the two surface areas...

The cfr gene associated with linezolid resistance has attracted wide attention. However, little is known about its prevalence and mode of transmission in Enterococcus faecalis. In this study, we investigate the prevalence and genetic environment of the cfr gene in 91 E. faecalis isolates collected from swine faecal swabs in 30 farms in Guangdong Province, China in 2012. A relatively high prevalence of cfr was identified in E. faecalis isolates (11/91, 12.1%) by PCR. All the cfr-positive E. faecalis strains had a multidrug-resistance phenotype including erythrocin, tetracycline, gentamicin, kanamicin and ciprofloxacin, except vancomycin and linezolid...

BACKGROUND: Due to the acuity and time sensitive needs of their clinical condition, patients presenting with certain emergent pathologies may lack capacity to provide meaningful prospective informed consent to participate in clinical research. For these reasons, these populations have often been excluded from research investigations. To mitigate this, regulations allowing Exception from Informed Consent (EFIC) (21 CFR 50.24) or Waiver of Informed Consent (WIC) (45 CFR 46.101) were developed in 1996...

BACKGROUND: Recently, the concept of pressure-bounded coronary flow reserve (PB-CFR) has been introduced. However, using pressure-only data, a substantial proportion of patients could not be classified into high or low PB-CFR and remained as indeterminate PB-CFR. The current study evaluated the prognostic implication of thermodilution-based CFR (thermo-CFR) in patients with indeterminate PB-CFR. METHODS: Among 199 patients (211 lesions) with indeterminate PB-CFR, 170 patients (179 lesions) with deferral of revascularization were analyzed for the current study...
