Purpose: Because of growing concerns about lung cancer in female never smokers, low-dose chest CT (LDCT) screening is often performed although it has never shown clinical benefits. We examine whether or not female never smokers really need annual LDCT screening when the initial LDCT showed negative findings. Materials and Methods: This retrospective cohort study included 4,365 female never smokers aged 40 to 79 years who performed initial LDCT from Aug 2002 to Dec 2007...

Enad Dawod, Michel Kahaleh
The diagnosis and management of pancreatic strictures, whether malignant or benign, remain challenging. The last 2 decades have seen dramatic progress in terms of both advanced imaging and endoscopic therapy. While plastic stents remain the cornerstone of the treatment of benign strictures, the advent of fully covered metal stents has initiated a new wave of interest in calibrating the pancreatic duct with fewer sessions. In malignant disease, palliation remains the priority and further data are necessary before offering systematic pancreatic stenting...

The recycling of biosolids and livestock manure in agriculture may lead to the introduction of antibiotic residues, i.e., parent molecule and transformation products, into amended soils. Their fate in soils can be approached through the assessment of their environmental availability. In this work, the environmental availability of sulfamethoxazole (SMX) and three transformation products (N(4)-acetyl-SMX, 3-amino-5-methylisoxazole, aniline) was assessed in soils amended with sludge compost or cow manure throughout a three-month incubation, using soft extractions with CaCl2, EDTA or cyclodextrin solutions...

AIMS: The standard sensor for abdominal pressure (Pabd) measurement in urodynamics (UD) is a rectal sensor. In patients where the rectum is not available due to prior surgery or when external anal sphincter (EAS) tone is poor, rectal sensor may slip, making Pabd recording unreliable. Vaginal Pabd measurement and wireless vaginal sensors have been tried. We present our preliminary series of a novel nasogastric tube (NG) sensor for Pabd measurement. METHODS: We identified patients undergoing UD with a NG Pabd sensor from a prospectively maintained UD database of a tertiary care urological center between July 2013 and December 2016...

BACKGROUND AND OBJECTIVES: Expanding residency training programs to address shortages in the primary care workforce is challenged by the present graduate medical education (GME) environment. The Medicare funding cap on new GME positions and reductions in the Health Resources and Services Administration (HRSA) Teaching Health Center (THC) GME program require innovative solutions to support primary care residency expansion. Sparse literature exists to assist in predicting the actual cost of incremental expansion of a family medicine residency program without federal or state GME support...

Importance: The issue of the aging physician and when to cease practice has been controversial for many years. There are reports of prominent physicians who practiced after becoming dangerous in old age, but the profession has not demonstrated the ability to prevent this. A mandatory retirement age could be discriminatory and take many competent physicians out of practice and risk a physician shortage. An increasing body of evidence regarding the relationship between physicians' age and performance has led organizations, such as the American College of Surgeons, to revisit this challenge...

Benzene kresoxim-methyl (BKM) is a promising broad-spectrum strobilurin fungicide widely used to control fungal pathogens in crops. However, information on its environmental fate is limited. To broaden our understanding of this fungicide's kinetic fate in aerobic soils, we labeled BKM with C on its benzoate ring and used ultralow-level liquid scintillation counting coupled with high-performance liquid chromatography analysis. Results show that degradation, mineralization, and bound residue (BR) formation of BKM was controlled by soil type and microbial community composition...

Biochar has been shown to influence soil CO and NO emissions following application to soil, but the presence of carbonates in biochars has largely confounded efforts to differentiate among labile and recalcitrant C pools in biochar and establish their timeframe of influence. Understanding the mechanism, magnitude, and duration of biochar C pools' influence on C and N dynamics is imperative to successful implementation of biochar for C sequestration. Here we therefore aim to assess biochar organic and inorganic C pool impacts on CO and NO emissions from soil amended with two untreated biochars, inorganic carbon (as NaCO), acid (HCl) and bicarbonate (NaHCO) extracts of the biochars, and acid and bicarbonate/acid-washed biochars during a 140-d soil incubation...

Poultry manure contains free and conjugated forms of the natural estrogens 17β-estradiol and estrone, which can be transported to receiving waters via runoff when land-applied. Previous studies have demonstrated estrogens in runoff from poultry manure-amended fields but have not tracked changes in estrogenicity within this water over time. Microbial conversion of conjugated estrogens (a major portion of water-extractable estrogens) to parent forms may result in temporary increases in estrogenicity in natural water bodies...

Eastern filbert blight (EFB), caused by the pyrenomycete (Peck) E. Müller, is a devastating disease of European hazelnut ( L) in the US Pacific Northwest. A dominant allele at a single locus from the obsolete pollenizer 'Gasaway' confers a high level of resistance to EFB. To identify the gene responsible for resistance, we initiated map-based cloning efforts in a population of 1488 seedlings that segregated for resistance. Chromosome walking was initiated using primers designed from eight previously identified random amplified polymorphic DNA markers linked to resistance...

Adaptation is a characteristic that enhances the survival or reproduction of organisms; selection is the critical process leading to adaptive evolution. Therefore, detecting selection is important in studying evolutionary biology. Changes in allele frequency are fundamental to adaptive evolution. The allele frequency of entire genes at the genomic scale is more intensive and precise for analyzing selection effects, compared with simple sequence repeat and single nucleotide polymorphism (SNP) alleles from nuclear gene fragments...
