Biosecurity Insights from the United States Swine Health Improvement Plan: Analyzing Data to Enhance Industry Practices.

Biosecurity practices aim to reduce the frequency of disease outbreaks in a farm, region, or country and play a pivotal role in fortifying the country's pork industry against emerging threats, particularly foreign animal diseases (FADs). This article addresses the current biosecurity landscape of the US swine industry by summarizing the biosecurity practices reported by the producers through the United States Swine Health Improvement Plan (US SHIP) enrollment surveys, and it provides a general assessment of practices implemented. US SHIP is a voluntary, collaborative effort between industry, state, and federal entities regarding health certification programs for the swine industry. With 12,195 sites surveyed across 31 states, the study provides a comprehensive snapshot of current biosecurity practices. Key findings include variability by site types that have completed Secure Pork Supply plans, variability in outdoor access and presence of perimeter fencing, and diverse farm entry protocols for visitors. The data also reflect the industry's response to the threat of FADs, exemplified by the implementation of the US SHIP in 2020. As the US SHIP program advances, these insights will guide industry stakeholders in refining biosecurity practices, fostering endemic re-emerging and FAD preparedness, and ensuring the sustainability of the swine industry in the face of evolving challenges.

Psychogenic tremor in a patient with a major depressive episode.

Psychogenic tremor is a variant of psychogenic movement disorder. Psychogenic tremor often starts in an abrupt manner and affects voluntary motor function, rapidly reaching maximum impairment for the patient. Patients often present with comorbid psychiatric disorders, including depression, anxiety and personality disorders. Overall prognosis is poor, with 80 to 90 percent of patients symptomatic after one year. The authors present the case of a 33-year-old woman who experienced an acute episode of psychogenic tremor. They review the literature on psychiatric and neurologic manifestations of psychogenic tremor, consider diagnostic and treatment implications and discuss overall prognosis of recovery for patients afflicted with psychogenic tremor.
