A Scoping Review of the Global Distribution of Causes and Syndromes Associated with Mid- to Late-Term Pregnancy Loss in Horses between 1960 and 2020.

Abstract: Equine pregnancy loss is frustrating and costly for horse breeders. The reproductive efficiency of mares has significant implications for a breeding operation's economic success, and widespread losses can have a trickle-down effect on those communities that rely on equine breeding operations. Understanding the causes and risks of equine pregnancy loss is essential for developing prevention and management strategies to reduce the occurrence and impact on the horse breeding industry. This PRISMA-guided scoping review identified 514 records on equine pregnancy loss and described the global spatiotemporal distribution of reported causes and syndromes. The multiple correspondence analysis identified seven clusters that grouped causes, syndromes, locations and pathology. Reasons for clustering should be the focus of future research as they might indicate undescribed risk factors associated with equine pregnancy loss. People engaged in the equine breeding industry work closely with horses and encounter equine bodily fluids, placental membranes, aborted foetuses, and stillborn foals. This close contact increases the risk of zoonotic disease transmission. Based on this review, research is required on equine abortion caused by zoonotic bacteria, including , and spp., because of the severe illness that can occur in people who become infected.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

The research paper is about identifying the causes and patterns of mid- to late-term pregnancy loss in horses globally, between 1960 and 2020. The findings from the study will help develop strategies to prevent and manage equine pregnancy loss.

Overview of the Study

The study is a comprehensive review of research connected with equine pregnancy loss. It is motivated by the serious economic consequences that widespread instances of such losses can have on breeding operations and those communities that depend on them. The research took a qualitative approach, gathering and analyzing data on horse pregnancies from over 500 records.

  • The analysis was guided by PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), a methodology that ensures systematic and transparent review of available literature.
  • It focused on the causes and syndromes associated with equine pregnancy loss, and presented spatiotemporal distribution (geographical and chronological distribution) of these causes and syndromes across the globe.

Findings of the Study

The study resulted in invaluable findings from the data:

  • Multiple correspondence analysis was conducted to find relationships between variables. This resulted in seven clusters that collected different causes, syndromes, locations, and pathology.
  • The clusters imply that the related variables may indicate yet unidentified risk factors for equine pregnancy loss that future research should focus on.

Associated Health Risks on Humans

The study also raised concerns on potential threats to human health:

  • Equine professionals, due to their close contact with horses, may encounter bodily fluids, placental membranes, aborted foetuses, and stillborn foals. This increases chances for zoonotic disease transmission, where diseases move from animals to humans.
  • Based on the findings, there is a need for further research on equine abortion caused by zoonotic bacteria as it can cause severe illness in affected individuals.
