Routine procedures carried out on piglets (i.e. castration, tail docking, teeth clipping, and ear notching) are considered painful. Unfortunately the efficacy of current pain mitigation modalities is poorly understood. The aim of this systematic review was to synthesize the existing primary scientific literature regarding the effectiveness of pain management interventions used for routine procedures on piglets. The review question was, 'In piglets under twenty-eight days old, undergoing castration, tail docking, teeth clipping, and/or methods of identification that involve cutting of the ear tissue, what is the effect of pain mitigation compared with no pain mitigation on behavioral and non-behavioral outcomes that indicate procedural pain and post-procedural pain?' A review protocol was designed a priori. Data sources used were Agricola (EBSCO), CAB Abstracts (Thomson Reuters), PubMed, Web of Science (Thomson Reuters), BIOSIS Previews (Thomson Reuters), and ProQuest Dissertations & Theses Full Text. No restrictions on year of publication or language were placed on the search. Eligible studies assessed an intervention designed to mitigate the pain of the procedures of interest and included a comparison group that did not receive an intervention. Eligible nonEnglish studies were translated using a translation service. Two reviewers independently screened titles and abstracts for relevance using pre-defined questions. Data were extracted from relevant articles onto pre-defined forms. From the 2203 retrieved citations forty publications, containing 52 studies met the eligibility criteria. In 40 studies, piglets underwent castration only. In seven studies, piglets underwent tail docking only. In one study, piglets underwent teeth clipping only, and in one study piglets underwent ear notching only. Three studies used multiple procedures. Thirty-two trial arms assessed general anesthesia protocols, 30 trial arms assessed local anesthetic protocols, and 28 trial arms assessed non-steroidal antiinflammatory drugs (NSAIDs) protocols. Forty-one trial arms were controls where piglets received either placebo or no treatment. Forty-five outcomes were extracted from the studies, however only the results from studies that assessed cortisol (six studies), b-endorphins (one study), vocalisations (nine studies), and pain-related behaviors (nine studies) are reported. Other outcomes were reported in only one or two studies. Confident decision making will likely be difficult based on this body of work because lack of comprehensive reporting precludes calculation of the magnitude of pain mitigation for most outcomes.

Piglets reared in swine production in the USA undergo painful procedures that include castration, tail docking, teeth clipping, and identification with ear notching or tagging. These procedures are usually performed without pain mitigation. The objective of this project was to develop recommendations for pain mitigation in 1-to 28-day-old piglets undergoing these procedures. The National Pork Board funded project to develop recommendations for pain mitigation in piglets. Recommendation development followed a defined multi-step process that included an evidence summary and estimates of the efficacies of interventions. The results of a systematic review of the interventions were reported in a companion paper. This manuscript describes the recommendation development process and the final recommendations. Recommendations were developed for three interventions (CO 2 /O 2 general anesthesia, non-steroidal anti-inflammatory drugs (NSAIDs), and lidocaine) for use during castration. The ability to make strong recommendations was limited by low-quality evidence and strong certainty about variation in stakeholder values and preferences. The panel strongly recommended against the use of a CO 2 /O 2 general anesthesia mixture, weakly recommended for the use of NSAIDs and weakly recommended against the use of lidocaine for pain mitigation during castration of 1-to 28-day-old piglets.

ObjectiveThe objective of this review was to update a systematic review of associations between living near an animal feeding operation (AFO) and human health.MethodsThe MEDLINE® and MEDLINE® In-Process, Centre for Agricultural Biosciences Abstracts, and Science Citation Index databases were searched. Reference lists of included articles were hand-searched. Eligible studies reported exposure to an AFO and an individual-level human health outcome. Two reviewers performed study selection and data extraction.ResultsThe search returned 3702 citations. Sixteen articles consisting of 10 study populations were included in the analysis. The health outcomes were lower and upper respiratory tracts, MRSA, other infectious disease, neurological, psychological, dermatological, otologic, ocular, gastrointestinal, stress and mood, and other non-infectious health outcomes. Most studies were observational and used prevalence measures of outcome. An association between Q fever risk and proximity to goat production was reported. Other associations were unclear. Risk of bias was serious or critical for most exposure-outcome associations. Multiplicity (i.e., a large number of potentially correlated outcomes and exposures assessed on the same study subjects) was common in the evidence base.ConclusionsFew studies reported an association between surrogate clinical outcomes and AFO proximity for respiratory tract-related outcomes. There were no consistent dose-response relationships between surrogate clinical outcome and AFO proximity. A new finding was that Q fever in goats is likely associated with an increased Q fever risk in community members. The review results for the non-respiratory health outcomes were inconclusive because only a small number of studies were available or the between-study results were inconsistent.Systematic review registrationPROSPERO CRD42014010521 Electronic supplementary materialThe online version of this article (doi:10.1186/s13643-017-0465-z) contains supplementary material, which is available to authorized users.

There was no strong evidence that any one intervention protocol (acid temperature, acid concentration, water temperature) was clearly superior to others for Salmonella control.

SUMMARYThis final report summarizes the results of two reviews and a scoping study related to Canine leishmaniosis (CanL). Three objectives were addressed in this project. Objective 1 was to summarize relative sensitivity and specificity estimates of assays used to detect infection in dogs with Leishmania infantum in studies of naïve dogs in areas where Leishmania infantum infection is endemic. Objective 2 was to summarize data available to estimate the prevalence of parasitological cure (failure to detect organism) after a 12-month follow-up period in animals treated with meglumine antimoniate, miltefosine, and allopurinol or combinations of these drugs for canine leishmaniosis. Objective 3 was to assess diagnostic test characteristics of PCR assays and serological assays (ELISA or IFAT) from studies that use experimental models of Canine leishmaniosis. The same comprehensive search was used for all objectives. The searches yielded 7,405 records. After duplicates were removed, 3,865 records remained. Of these, 243 were broadly identified as diagnostic test evaluation studies and at the 2 nd level of screening 18 were considered longitudinal studies. The 18 references were then assessed based on the full text and 7 were considered relevant to the review. The assays assessed by these studies were PCR on skin, buffy coat, bone marrow, blood and conjunctiva, and IFAT and ELISA. For objective 2, 40 potentially relevant records were identified as treatment comparison studies. After full-text screening, 13 studies were included in the review. The treatments varied greatly, and few comparative efficacy estimates were provided. No treatment was associated with 100% cure after 180 days follow-up. For objective 3, 513 citations were identified and the full texts of 169 articles were obtained. Sixty-two articles described at least one of the assays requested (PCR, ELISA or IFAT) and 18 articles described the use of a PCR and either ELISA and/or IFAT.
