Management strategies for addressing contaminated sediments can include a wide range of actions, ranging from no action, to the use of engineering controls, to the use of more aggressive, intrusive activities related to removing, containing, or treating sediments because of environmental or navigation considerations. Risk assessment provides a useful foundation for understanding the environment...

UNLABELLED Fermented sausages, although presumed safe for consumption, sometimes cause serious bacterial infections in humans that may be deadly. Not much is known about why and when this is the case. We tested the hypothesis that residual veterinary antibiotics in meat can disrupt the fermentation process, giving pathogenic bacteria a chance to survive and multiply. We found that six commercia...

Background: Several studies have shown that neuromuscular block often persists in the recovery room even after the administration of acetyl cholinesterase inhibitors. This postoperative residual neuromuscular paralysis (PORP) may represent serious safety concerns, resulting in respiratory events like muscle weakness, desaturation, pulmonary collapse and acute respiratory failure(1). Methods: We...

Cardiovascular disease poses a major challenge for the 21st century, exacerbated by the pandemics of obesity, metabolic syndrome and type 2 diabetes. While best standards of care, including high-dose statins, can ameliorate the risk of vascular complications, patients remain at high risk of cardiovascular events. The Residual Risk Reduction Initiative (R3i) has previously highlighted atherogeni...

BACKGROUND Parasite clearance time after artemisinin-based combination therapy (ACT) may be increasing in Asian and African settings. The association between parasite clearance following ACT and transmissibility is currently unknown. METHODS We determined parasite clearance dynamics by duplex quantitative polymerase chain reaction (qPCR) in samples collected in the first 3 days after treatmen...

There is limited prognostic information to identify breast cancer patients who are at risk for late recurrences after adjuvant or neoadjuvant systemic therapy (AST). We evaluated the residual risk of recurrence and prognostic factors of 2838 patients with stage I-III breast cancer who were treated with AST between January 1, 1985, and November 1, 2001, and remained disease free for 5 years. Res...

BACKGROUND transurethral resection of bladder tumor (TURBT) is the first-line treatment fornon-muscle-invasive bladder cancer. We aimed to investigate the effect of probable risk factors on the positive rate of the repeated transurethral resection of bladder tumor performed 4-6 weeks after an initial TURBT in patients with non-muscle invasive bladder cancer in China. METHODS 134 patients with...

OBJECTIVES/HYPOTHESIS To review which type of cholesteatoma surgery, canal wall up (CWU) or canal wall down (CWD), provides the lowest risk for residual and/or recurrent disease in adults with primary acquired cholesteatoma. DATA SOURCES PubMed, Embase, CINAHL, the Cochrane Library, Scopus and Web of Science. STUDY DESIGN We selected articles comparing CWU with CWD, reporting on disease rec...

BACKGROUND It has been suggested that tooth loss in later life might increase dementia incidence. The objective of this analysis is to systematically review the current evidence on the relationship between the number of remaining teeth and dementia occurrence in later life. METHODS A search of multiple databases of scientific literature was conducted with relevant parameters for articles publ...

the total concentration and percentage of heavy metals content in the sediment of hashilan wetland, kermanshah province, was assessed in summer 2015. the total concentrations of cu, pb, and fe were around 18.57, 6.95 and 379.24 μg g-1, respectively. successive extractions of the samples showed a decreasing trend as follows: residual>organic matter>iron and manganese oxides>exchangeable parts. t...
