AbstractBackgroundArteriovenous fistulas (AVFs) are the preferred vascular access type in most hemodialysis patients. However, the optimal vascular access type in octogenarians and older (≥80 years) hemodialysis patients remains widely debated given their limited life expectancy and lower AVF maturation rates.MethodsAmong incident hemodialysis patients receiving care in a large national dialysis organization during 2007–2011, we examined patterns of vascular access type conversion in 1 year following dialysis initiation in patients &lt;80 versus ≥80 years of age. Among a subcohort of patients ≥80 years of age, we examined the association between vascular access type conversion and mortality using multivariable survival models.ResultsIn the overall cohort of 100 804 patients, the prevalence of AVF/arteriovenous graft (AVG) as the primary vascular access type increased during the first year of hemodialysis, but plateaued thereafter. Among 8356 patients ≥80 years of age and treated for &gt;1 year, those with initial AVF/AVG use and placement of AVF from a central venous catheter (CVC) had lower mortality compared with patients with persistent CVC use. When the reference group was changed to patients who had AVF placement from a CVC in the first year of dialysis, those with initial AVF use had similar mortality. A longer duration of CVC use was associated with incrementally worse survival.ConclusionsAmong incident hemodialysis patients ≥80 years of age, placement of an AVF from a CVC within the first year of dialysis had similar mortality compared with initial AVF use. Our data suggest that initial CVC use with later placement of an AVF may be an acceptable option among elderly hemodialysis patients.

AbstractBackgroundLow socioeconomic status (SES) is associated with cardiovascular disease (CVD) risk, but its association with different markers of SES may be heterogeneous by sex and race/ethnicity.MethodsWe have examined the relationships of four SES markers (education, family income, occupation and neighborhood SES) to ideal cardiovascular health (ICH), an index formed by seven variables. A total of 6792 cohort participants from six regions in the USA: Baltimore City and Baltimore County, MD; Chicago, IL; Forsyth County, NC; Los Angeles County, CA; New York, NY; and St. Paul, MN of the Multi-Ethnic Study of Atherosclerosis (MESA) (52.8% women) were recruited at baseline (2000–2) and included in the present analysis.ResultsICH was classified as poor, intermediate or ideal. Level of education was significantly and inversely associated with ICH in non-Hispanic White men and women, in Chinese-American and Hispanic American men and African-American women. Family income was inversely and significantly associated with poor ICH in African-American men only.ConclusionsWe conclude that the strength of the associations between some SES markers and ICH differ between sexes and race/ethnic groups.
Robustly Optimal Auctions with Unknown Resale Opportunities
Authors: Carroll Gabriel , Segal Ilya 
Published: July 2018

AbstractThe standard revenue-maximizing auction discriminates against a priori stronger bidders so as to reduce their information rents. We show that such discrimination is no longer optimal when the auction’s winner may resell to another bidder, and the auctioneer has non-Bayesian uncertainty about such resale opportunities. We identify a “worst-case” resale scenario, in which bidders’ values become publicly known after the auction and losing bidders compete Bertrand-style to buy the object from the winner. With this form of resale, misallocation no longer reduces the information rents of the high-value bidder, as he could still secure the same rents by buying the object in resale. Under regularity assumptions, we show that revenue is maximized by a version of the Vickrey auction with bidder-specific reserve prices, first proposed by Ausubel and Cramton (2004). The proof of optimality involves constructing Lagrange multipliers on a double continuum of binding non-local incentive constraints.

Abstract
Translating effective research into community practice is critical for improving breast cancer (BC) survivor health. The purpose of this study is to utilize the RE-AIM framework to evaluate the translational potential of Project MOVE, an innovative intervention focused on increasing physical activity (PA) in BC survivors. A mixed-methods design, including a self-report questionnaire, accelerometry, focus groups, and interviews, was used to inform each RE-AIM dimension. Reach was evaluated by the representativeness of participants. Effectiveness was reflected by change in PA levels and perceptions of satisfaction and acceptability. Adoption was examined using participants’ perceived barriers/facilitators to program uptake. Implementation was examined by participants’ perceived barriers/facilitators to implementing the program. Maintenance was assessed by participant retention. Assessments occurred at baseline and 6-months. Mixed analysis of variance and content analysis were used to analyze the data. A total of 87 participants participated in Project MOVE and were demographically comparable to similar studies (Reach). Participants indicated high levels of program satisfaction (88%) and previously inactive survivors’ significantly increased PA levels from baseline to 6-month follow-up (Effectiveness). Participants reported that a program focused on PA rather than disease helped them overcome barriers to PA (Adoption) and having leaders with BC and exercise expertise was essential to accommodate population specific barriers (Implementation). At 6-months, participant retention was 83% (Maintenance). Project MOVE is an acceptable, practical, and effective program for engaging BC survivors in PA and has the potential to be highly transferable to other populations and regions.
The Doctor of Plant Medicine Program at the University of Florida: Growers, Agricultural Agencies, and Industries Need Plant Doctors
Authors: Agrios George N. 
Published: July 2018

The Doctor of Plant Medicine program is a new graduate doctorate program that ushers in a new discipline, Plant Medicine, and a new profession, the Plant Doctor. Like anything else that is new, it has its share of skeptics. Plant medicine does not compete with or supplant any of the existing disciplines. It fills a central void left by the specialization of each discipline. Plant medicine does not do either basic or applied research but it depends for it and it borrows from the research done by PhDs of all the related disciplines including soils, agronomy, horticulture, entomology, nematology, plant pathology, etc. Plant medicine is an applied, problem-solving discipline and plant doctors learn to solve health problems of plants by learning to identify the biotic or abiotic cause of any such problem and by providing recommendations for its management or control.

Use of Neonicotinoid Insecticides Applied to Soil and Seed for Green Peach Aphid Management on Spinach
Authors: McLeod Paul , Eaton Steven , Martin Larry 
Published: July 2018

The green peach aphid, Myzus persicae Sulzer, a common pest of spinach produced in the Arkansas River Valley of western Arkansas and eastern Oklahoma, is currently managed with foliar applications of neonicotinoid insecticides. Data reported herein indicate that the neonicotinoid insecticdes, imidacloprid and thiamethoxam, can also be applied to spinach seed and into the soil for effective aphid management. In greenhouse studies both imidacloprid (Gaucho) and thiamethoxam (Cruiser) seed treatments were effective against adults and prevented the establishment of juvenile aphids for a period of 12 weeks after planting. Similar results were obtained in field studies. Regardless of rate, each of the neonicotinoid seed treatments significantly reduced the number of aphids when compared to aphid population levels on non-treated spinach. In addition to the seed treatments, in-furrow applications also resulted in significantly lower aphid numbers than on plants in plots not receiving the applications. Tests also demonstrated that imidacloprid (Admire) effectively managed aphid populations after being injected into the soil. Of the seed and soil applications evaluated, the only application method currently available is use of imidacloprid applied into the soil. This method currently offers the spinach producer an alternative management tool for green peach aphid control on spinach. As the labels of imidacloprid and other neonicotinoid insecticides are expanded to include additional use patterns such as seed treatments, effective alternatives to foliar sprays should prove effective for aphid management on spinach.

First Report of Phytophthora ramorum Infecting Grand fir in California
Authors: Riley Kathleen L. , Chastagner Gary A. , Blomquist Cheryl 
Published: July 2018

Phytophthora ramorum was detected on grand fir in 2003 and 2005 in a Christmas tree plantation near Los Gatos, CA, in association with infected California bay laurel. Isolates derived from stem lesions were used to inoculate grand fir seedlings in two tests. Isolations from lesions on inoculated plants were positive for P. ramorum in both tests. This work provides the completion of Koch's postulates to establish grand fir as a host of P. ramorum. The potential for grand fir to be infected within its native range is unknown.

Published: July 2018

Turkish filbert is a medium-sized tree native to southwest Asia and southeast Europe. It is well-adapted to urban settings, although its use as an ornamental in the United States has been limited. In 2010 and 2011, Turkish filberts at a site in Boulder, CO, exhibited leaf spotting, partial defoliation, and shoot dieback. Xanthomonas arboricola pv. corylina and Pseudomonas syringae pv. syringae were consistently isolated from leaf spots whereas X. arboricola pv. corylina was the only bacterium isolated from blight shoots. This is the first report of X. arboricola pv. corylina on Turkish Filbert in Colorado. Accepted for publication 7 March 2012. Published 17 May 2012.
Boscalid Insensitivity Documented in Didymella bryoniae Isolated from Watermelon in Florida and North Carolina

Published: July 2018

The fungicide Pristine, a commercial mixture of pyraclostrobin and boscalid, has been used widely on watermelon and other cucurbits to control gummy stem blight, caused by the fungus Didymella bryoniae. Since 2007, isolates of D. bryoniae insensitive to boscalid have been found in Georgia, Indiana, and South Carolina. Most isolates of D. bryoniae obtained in 2009 and 2010 from diseased watermelon leaves collected in several counties in Florida and North Carolina were found to be insensitive to boscalid using in vitro assays. Gummy stem blight would not be effectively managed with Pristine in any of the counties where samples were collected due to the high frequency of insensitivity to boscalid. Fortunately growers can instead use several triazole fungicides registered for use on cucurbits since 2009. Accepted for publication 30 March 2012. Published 18 May 2012.
Resistance to Frogeye Leaf Spot in Selected Soybean Accessions in MG I through MG VI
Authors: Mengistu Alemu , Bond Jason , Mian Rouf , Nelson Randall , Shannon Grover , Wrather Allen 
Published: July 2018

Frogeye leaf spot (FLS) caused by Cercospora sojina Hara is a disease of soybean [Glycine max (L.) Merr.] that causes significant seed yield loss in warm, humid environments worldwide. The Rcs3 gene in soybean has been reported to condition resistance to all known races of C. sojina. The objectives of this study were to: (i) identify maturity group (MG) I to VI accessions resistant to C. sojina race 11 by field screening at two locations; and (ii) determine if the FLS resistance of the symptomless soybean accessions is likely to be conditioned by the Rcs3 allele. A total of 260 accessions including 12 differentials were evaluated for reaction to race 11 in field trials in Missouri and Illinois during 2009, and 20 accessions that did not develop symptoms were retested in 2010 to validate their resistance. The 20 accessions remained resistant and were tested for the potential presence of Rcs3 allele using molecular markers; and none was predicted to carry the Rcs3 allele. These accessions may contain novel loci for FLS resistance and may be used to broaden the base for developing soybean cultivars with frogeye leaf spot resistance.

Effect of Geosmithia morbida Isolate and Temperature on Canker Development in Black Walnut
Authors: Freeland Emily , Cranshaw Whitney , Tisserat Ned 
Published: July 2018

Thousand cankers disease of black walnut (Juglans nigra) is the result of aggressive feeding by the walnut twig beetle (Pityophthorus juglandis) and extensive cankering around beetle galleries caused by the fungus Geosmithia morbida. We developed a consistent, reproducible inoculation technique to screen black walnut trees for their reaction to canker development following inoculation with G. morbida. Canker areas in one-year-old trees were not affected by the location on the stem that inoculations were made. Differences in aggressiveness of G. morbida isolates, representing different rDNA ITS haplotype groups, to black walnut were observed in some experiments. However, these differences were small and evidence indicates that a single, highly aggressive haplotype is not responsible for the current TCD epidemic. Cankers formed in black walnut at all temperatures tested, but they were consistently smaller at 32/20°C day/night temperatures compared to 25/20°C. Although G. morbida is thermotolerant, higher temperatures may not enhance canker development. Accepted for publication 1 May 2012. Published 18 June 2012.

Published: July 2018

Fusarium virguliforme, the soilborne fungus that causes sudden death syndrome (SDS), and Heterodera glycines, the soybean cyst nematode (SCN), are economically important pathogens that often occur concomitantly in Kansas soybean fields. To examine F. virguliforme and H. glycines interactions across multiple environments, four soybean genotypes with different levels of resistance to SDS and SCN were planted at three to four locations in northeastern Kansas in 2008 and 2009. Pathogen population densities were quantified at planting (Pi), midseason (Pm), and harvest (Pf). At harvest, SDS AUDPC, F. virguliforme root population densities, H. glycines reproductive factors (RF), and yield were determined. The performance of resistant (R) genotypes varied with environment and disease pressure, but SDS-R genotypes were associated with 36% greater yields than SDS-susceptible (S) genotypes in high SDS environments. Even moderate levels of SCN resistance reduced SDS disease severity in SDS-S genotypes. Negative correlations (P ≤ 0.05) were observed between yield and AUDPC, and yield and F. virguliforme root population densities. A regression model that combined both of these covariates explained 57% of the yield variation. Disease severity was positively correlated with H. glycines Pi, but negatively correlated with RF. The data emphasize the importance of combining SDS and SCN host resistance in fields with a history of both diseases. Accepted for publication 6 November 2013. Published 27 January 2014.
Phytophthora nicotianae Can Cause Both Crown Rot and Foliage Blight on Phlox paniculata in South Carolina
Authors: Drechsler Daniel T. , Jeffers Steven N. , Bridges William C. 
Published: July 2018

Phytophthora nicotianae is a common pathogen of many herbaceous perennial plants, and this pathogen has been found causing disease on garden phlox (Phlox paniculata) in wholesale nurseries in South Carolina for a number of years. However, the relationship between P. nicotianae and garden phlox has not been studied or reported previously. Using Koch's postulates and standard inoculation methods for Phytophthora spp., P. nicotianae was found to cause crown rot on P. paniculata when potting medium was infested with colonized vermiculite and to cause foliage blight when aerial parts of the plant were inoculated with an aqueous suspension of zoospores. Foliage blight was more similar to symptoms we observed on garden phlox plants in wholesale nurseries, but crown rot also has been observed previously on plants in these nurseries. The cause of these two diseases was confirmed, but reproduction of Phytophthora foliage blight under experimental conditions was inconsistent. Thus, other factors not yet identified may play a role in the development of Phytophthora foliage blight on garden phlox in nurseries in South Carolina. Accepted for publication 1 September 2014.

Published: July 2018

Abundant, frequent rains along with humid and cloudy conditions during the early part of the 2015 growing season provided conducive conditions for an unusually severe outbreak of zonate leaf spot and rough leaf spot in a block of sorghum lines at the Texas A&M AgriLife Research Farm, Burleson County, near College Station, Texas. This afforded the opportunity to evaluate these lines for reaction to these diseases, which normally occur at trace levels in this area. Out of 181 sorghum lines, including a subset of the sorghum association panel, a total of 13 lines, including Dorado, Sureno, PI576434, PI656005, PI656034, PI656075, PI656024, and PI598070, were resistant to both diseases. These lines could be used in breeding programs to introgress the genes for resistance to both diseases into other adapted lines. Accepted for publication 8 December 2015. Published 14 December 2015.
Nontuberculous mycobacteria infection risk in medical tourism
Authors: Avanzi Antonina , Bierbauer Kristin , Vales-Kennedy Guillermo , Covino Jean 
Published: July 2018

ABSTRACT
The increasing popularity of medical tourism among US citizens has led to the rising incidence of nontuberculous mycobacteria (NTM) infections from cosmetic surgery performed in other countries. Clinicians must be aware of these infections and the potential difficulties in treating them. The most common NTM species isolated from cutaneous infections in medical tourists is Mycobacterium abscessus. Because many NTM species are antibiotic resistant, combination therapy is needed to combat skin and soft-tissue NTM infections in patients who had cosmetic procedures performed in foreign countries.

Objectives:To identify the key points for improving severe maternal morbidity by analyzing pregnancy-related ICU admissions in Beijing.Design:This was a retrospective, multicenter cohort study.Setting:Three ICUs in tertiary hospitals in Beijing.Patients:A total of 491 severe maternal cases in any trimester of pregnancy or within 42 days of delivery were reviewed between January 1, 2008, and December 31, 2016.Interventions:None.Measurements and Main Results:Among 491 obstetric ICU admissions (median Sequential Organ Failure Assessment score, 2) out of 87,850 hospital deliveries (a frequency of 5.6 admissions per 1,000 deliveries), the leading diagnoses were postpartum hemorrhage (170; 34.62%), hypertensive disorders of pregnancy (156; 31.77%), and cardio-cerebrovascular diseases (78; 15.9%). Comparing 2008–2011 to 2012–2016, the rates of maternal mortality (2.5% vs 1.9%;p= 0.991) and fetal loss (8.5% vs 8.6%;p= 0.977) did not decrease significantly, whereas the rates of ICU admission (3.05% vs 7.85%;ptrends < 0.001) and postpartum hemorrhage (23% vs 38.5%;p= 0.002) increased. Hypertensive disorder (150/156; 96.2% transferred to the ICU postpartum, 24/28 women with fetal loss transferred from lower-level hospitals) was an independent maternal factor associated with fetal loss, and infections were the leading cause of maternal death (6/10) in the ICU.Conclusions:Our study highlights the increasing rate of intensive care admissions for postpartum hemorrhage. Improving prenatal care quality for pregnancy-induced hypertension and sepsis at lower-level hospitals may improve maternal and fetal outcomes. Specifically, providing more effective regional cooperation before transfer and shifting patients who require continuous surveillance but not necessarily intensive care to a transitional ward in a tertiary hospital would provide more ICU beds for more prenatal intensive care for the most complex medical conditions.
