Members of project team recently gave two presentations at the recent 29th International Symposium on Epidemiology in Occupational Health, EPICOH, conference in Mumbai. Samuel Fuhrimann’s presentation was entitled “Occupational Exposure to Pesticides And Neurobehavioral Outcomes: Impact Of Different Exposure Measures on the Association” and Hans Kromhout’s “Performance of self reported and urinary biomarker based measures of exposure to glyphosate and mancozeb in a study on sleep problems among smallholder farmers in Uganda”. Links to these presentations can be found at our conferences and publications page.
September / October 2022
The project team have been busy presenting their work at several scientific forum. Will Mueller presented findings linked to our WP3 work at the ISEE conference. Will provided an overview of our analysis of urinary biomarker concentrations from samples collected from farmers in Malaysia, Uganda and the UK. Hans Kromhout and Karen Galea provided high level overviews of the IMPRESS publications to date at the ISES conference in Lisbon and UK & Ireland Exposure Sciences meetings. Links to these presentations can be found at our conferences and publications page.
Well done Johan Ohlander (lead author) on the publication of the IMPRESS article “Impact of occupational pesticide exposure assessment method on risk estimates for prostate cancer, non-Hodgkin’s lymphoma and Parkinson’s disease: results of three meta-analyses” in the journal Occupational and Environmental Medicine. The findings are summarised as follows, with the full text of the paper being available here
- We conducted three meta-analyses to specifically investigate how the type of exposure assessment method influenced summary risk estimates of prostate cancer (PC), non Hodgkin’s lymphoma (NHL) and Parkinson’s disease.
- Exposure assessment method was not associated with significantly different summary risk estimates for any of the analysed health outcomes.
- Study design (for cancer studies), publication year (for studies on NHL) and geographic region where the study was conducted (for PC), showed a larger effect on the summary risk estimates than the applied exposure assessment method.
The project team are pleased to announce a further publication from the IMPRESS project. Will Mueller led authorship of our manuscript which reports “Recall of exposure in UK farmers and pesticide applicators: trends with follow-up time”. This manuscript is freely available from here.
What a great start to the New Year! Delighted to announce another publication from the IMPRESS project. Will Mueller led authorship of our manuscript which aimed to evaluate Ugandan smallholder farmers’ recall of pesticide use and exposure determinants over a two-year period. This manuscript is freely available from here.
The IMPRESS project presented three oral presentations at the EPICOH conference, 25-28th October. These included reporting on a pilot study aimed at investigating urinary pesticide metabolite levels among Malaysian farm workers (26th October) (linked to our WP3 work), assessment of the recall ability of pesticide users in Uganda and the UK (linked to our WP2 work) and the impact of occupational pesticide exposure assessment methods on risk estimates for prostate cancer, non-Hodgkin’s lymphoma and Parkinson’s (linked to our WP4 work) (both 28th October).
At the 14th UK/Ireland Occupational & Environmental Epidemiology Meeting, 4th June 2021, we presented some of our findings on recall bias in epidemiological studies of pesticide use in the IMPRESS study. A link to the presentation can be found at our conferences and publications page.
The Food and Agriculture Organization of the United Nations (FAO) and World Health Organization (WHO) have recently published ‘Guidelines for personal protection when handling and applying pesticide – International Code of Conduct on Pesticide Management’. These guidelines are intended to provide guidance for preventing the risk of pesticides by reducing exposure with use of effective personal protection, particularly personal protective equipment. The guidelines are designed primarily for use by government authorities in charge of pesticide management and risk reduction but may also be useful in sectors such as the pesticide industry, nongovernmental organizations and other relevant entities.
The project team are also pleased to advise that our publication “Improving Exposure Assessment Methodologies for Epidemiological Studies on Pesticides: Study Protocol” has now been published online by JMIR Research Protocols. This publication, led by our colleagues at HSE, is freely available from here
The project team are pleased to advise that our publication “Systematic review of methods used to assess exposure to pesticides in occupational epidemiology studies, 1993-2017” has now been published online by OEM. This publication summarises results from a review exercise led by our colleagues at the Institute for Risk Assessment Studies (IRAS), the Netherlands.
Our WP2 and WP3 work in Ugandan and UK farmers has now stopped and has now entered the data and laboratory analysis phase.
Participant recruitment for the component of IMPRESS associated to the Study of Health in Agricultural Work (SHAW) recently commenced and will be ongoing over the coming months.
A paper describing the generic protocol for the methods applied within WP2 and WP3 of IMPRESS has been submitted for publication in the peer reviewed literature. Writing of the paper has been led by Kate Jones from the Health and Safety Executive, UK.
Our WP2 and WP3 work has been expanded to include surveying and biological monitoring of participants in an ongoing study among small scale farmers from Uganda with ethical clearances being sought from the relevant national bodies. The work is led by the Institute for Risk Assessment Studies (IRAS), the Netherlands.
Field work in the Malaysian part of the study has been completed with the study entering its analytical phase.
The first research outputs of the study have been submitted for publication in the peer reviewed literature. The submitted article summarises results from a review exercise led by our colleagues at the Institute for Risk Assessment Studies (IRAS), the Netherlands mapping the use of the different exposure assessment approaches in epidemiological studies published within the last 25 years.
Ethical clearance for the component of IMPRESS associated to the Study of Health in Agricultural Work (SHAW) has been obtained by the University of Manchester Ethics Committee (Ref: 2019-5987-9976).
The UK components of the study related to the PIPAH study population within WP2 and WP3 have been granted ethical approval by the ethics committee of Sheffield University (reference no. HSL28/2018 and HSL29/2019, respectively). Field work has been initiated with the first invitation and consent letters being distributed to potential participants of the PUHS and PIPAH studies.
A paper providing an outline of the study and involved methodology has been published at the journal of Outlooks on Pest Management. The papers full reference is “Galea, K.S., Basinas, I., Cherrie, J.W., Fuhrimann, S., Harding, A.H., Jones, K., Kromhout, H., Ohlander, J., Povey, A., Ahmad, Z.N.S. and van Tongeren, M., 2019. Impress: Improving Exposure Assessment Methodologies for Epidemiological Studies on Pesticides. Outlooks on Pest Management, 30(1), pp.18-19.”. The full text of the paper is available here.
