Complex Interactions Between Weather, and Microbial and Physicochemical Water Quality Impact the Likelihood of Detecting Foodborne Pathogens in Agricultural Water.

Frontiers in microbiology

Weller D, Brassill N, Rock C, Ivanek R, Mudrak E, Roof S, Ganda E, Wiedmann M.
PMID: 32117154
Front Microbiol. 2020 Feb 06;11:134. doi: 10.3389/fmicb.2020.00134. eCollection 2020.

Agricultural water is an important source of foodborne pathogens on produce farms. Managing water-associated risks does not lend itself to one-size-fits-all approaches due to the heterogeneous nature of freshwater environments. To improve our ability to develop location-specific risk management...

Eating fish for two.

Nutrition bulletin

Strain J.
PMID: 25132804
Nutr Bull. 2014 Jun;39(2):181-186. doi: 10.1111/nbu.12088.

This article is based on the British Nutrition Foundation's Annual Lecture, which focused on maternal fish consumption and the effects of methylmercury (MeHg) on fetal development, with respect to current guidance and policy on fish consumption during pregnancy. Fish...

Landscape, Water Quality, and Weather Factors Associated With an Increased Likelihood of Foodborne Pathogen Contamination of New York Streams Used to Source Water for Produce Production.

Frontiers in sustainable food systems

Weller D, Belias A, Green H, Roof S, Wiedmann M.
PMID: 32440656
Front Sustain Food Syst. 2020 Feb;3. doi: 10.3389/fsufs.2019.00124. Epub 2020 Feb 06.

There is a need for science-based tools to (i) help manage microbial produce safety hazards associated with preharvest surface water use, and (ii) facilitate comanagement of agroecosystems for competing stakeholder aims. To develop these tools an improved understanding of...

Digit ratio, a proposed marker of the prenatal hormone environment, is not associated with prenatal sex steroids, anogenital distance, or gender-typed play behavior in preschool age children.

Journal of developmental origins of health and disease

Barrett E, Thurston SW, Harrington D, Bush NR, Sathyanarayana S, Nguyen R, Zavez A, Wang C, Swan S.
PMID: 33336644
J Dev Orig Health Dis. 2020 Dec 18;1-10. doi: 10.1017/S2040174420001270. Epub 2020 Dec 18.

Prenatal hormones have been proposed as key factors impacting child development as well as long-term health and disease. Digit ratio (the ratio of the lengths of the second to fourth digits; 2D:4D) has been proposed as a sexually dimorphic,...

A General Class of Test Statistics for Van Valen's Red Queen Hypothesis.

Journal of applied statistics

Wiltshire J, Huffer FW, Parker WC.
PMID: 24910489
J Appl Stat. 2014 Sep 01;41(9):2028-2043. doi: 10.1080/02664763.2014.907394.

Van Valen's Red Queen hypothesis states that within a homogeneous taxonomic group the age is statistically independent of the rate of extinction. The case of the Red Queen hypothesis being addressed here is when the homogeneous taxonomic group is...

Microbial Source-Tracking Reveals Origins of Fecal Contamination in a Recovering Watershed.

Water

Green H, Weller D, Johnson S, Michalenko E.
PMID: 32587756
Water (Basel). 2019 Oct;11(10). doi: 10.3390/w11102162. Epub 2019 Oct 17.

Fecal contamination of waterbodies due to poorly managed human and animal waste is a pervasive problem that can be particularly costly to address, especially if mitigation strategies are ineffective at sufficiently reducing the level of contamination. Identifying the most...

Outlier Identification in Model-Based Cluster Analysis.

Journal of classification

Evans K, Love T, Thurston SW.
PMID: 26806993
J Classif. 2015 Apr 01;32(1):63-84. doi: 10.1007/s00357-015-9171-5. Epub 2015 Mar 10.

In model-based clustering based on normal-mixture models, a few outlying observations can influence the cluster structure and number. This paper develops a method to identify these, however it does not attempt to identify clusters amidst a large field of...

USING THE SEYCHELLES CHILD DEVELOPMENT STUDY TO CLUSTER MULTIPLE OUTCOMES INTO DOMAINS TO IMPROVE ESTIMATION OF THE OVERALL EFFECT OF MERCURY ON NEURODEVELOPMENT.

Mathematics for applications

Lalonde A, Love T.
PMID: 30636979
Math Appl. 2018;7(1):53-62. doi: 10.13164/ma.2018.05.

Environmental exposure effects on human development can be small and difficult to detect due to the nature of observational data. In the Seychelles Child Development Study, researchers examined the effect of prenatal methylmercury exposure using a battery of tests...

The effect of air pollution on the transcriptomics of the immune response to respiratory infection.

Scientific reports

Croft DP, Burton DS, Nagel DJ, Bhattacharya S, Falsey AR, Georas SN, Hopke PK, Johnston CJ, Kottmann RM, Litonjua AA, Mariani TJ, Rich DQ, Thevenet-Morrison K, Thurston SW, Utell MJ, McCall MN.

Sci Rep. 2021 Sep 30;11(1):19436. doi: 10.1038/s41598-021-98729-8.

Combustion related particulate matter air pollution (PM) is associated with an increased risk of respiratory infections in adults. The exact mechanism underlying this association has not been determined. We hypothesized that increased concentrations of combustion related PM would result...

Serum cytokines are associated with n-3 polyunsaturated fatty acids and not with methylmercury measured in infant cord blood in the Seychelles child development study.

Environmental research

Spence T, Zavez A, Allsopp PJ, Conway MC, Yeates AJ, Mulhern MS, van Wijngaarden E, Strain JJ, Myers GJ, Watson GE, Davidson PW, Shamlaye CF, Thurston SW, McSorley EM.

BACKGROUND: Maternal fish consumption increases infant methylmercury (MeHg) exposure and polyunsaturated fatty acid (PUFA) concentrations. The n-3 PUFA are regulators of inflammation while MeHg may impact the cord cytokine profile and, subsequently, contribute to immune mediated outcomes. This study...

Predictive Models May Complement or Provide an Alternative to Existing Strategies for Assessing the Enteric Pathogen Contamination Status of Northeastern Streams Used to Provide Water for Produce Production.
