Suicide in veterinary medicine: A literature review.

Veterinarians are commonly exposed to occupational stressors, including excessive workload and financial constraints. These stressors can lead to psychological distress, which typically results in mental health disorders such as depression, anxiety, and burnout and can even culminate in suicide attempts or suicide deaths. Risk factors associated with poor mental health and high rates of suicide in veterinary practitioners include continuous exposure to challenging scenarios, such as interpersonal conflicts, performing euthanasia, and easy access to lethal means of suicide, such as opioids and anesthetics. The previous studies highlight the urgent need for a better understanding of predisposing factors, mental health-related improvements in the professional environment, and the subsequent establishment of primary mental health-related care policies. Effective ways to promote mental health and prevent suicide may include social support, resilience, developing coping skills, promoting a healthy work environment, and discouraging perfectionist behaviors. This review aimed to summarize findings in studies that have investigated mental health and suicide in veterinarians and veterinary students and highlight measures that could be implemented as options for mental health promotion and suicide prevention.

High prevalence of anti-Toxoplasma gondii antibodies in beef cattle in Midwestern Brazil.

The present study aimed to determine the seroprevalence of anti-Toxoplasma gondii antibodies using an indirect immunofluorescence assay (IFA-IgG) in 3,814 cows aged ≥ 24 months belonging to 353 beef farms in the Mato Grosso state. Additionally, we aimed to identify the possible risk factors associated with seropositivity in Mato Grosso, which encompasses three biomes (Amazon, Cerrado, and Pantanal) of Brazil. Analysis of 3,814 samples observed that 1,307 animals were positive for anti-T. gondii antibodies (IFA-IgG ≥ 64), with an animal-level seroprevalence of 34.27%. Herd-level seroprevalence was 92.07%. In the animal-level model, cows raised in the Amazon and Pantanal biomes and breed studies on European and Zebu or hybrid were found to be at risk for T. gondii seropositivity. Prevalence of anti-T. gondii antibodies in cows destined for human consumption was found to be widely distributed throughout the entire study area. Further studies are required to assess the impact of beef in the possible transmission of toxoplasmosis to humans residing in the region and establish additional control measures for this protozoan mainly on beef herds raised in the Amazon and Pantanal biomes, where the highest values of seroprevalence were observed.
