Background: Recent cases of donor-derived infections raise the question of how best to screen donors without excessive restriction of the donor pool.
Methods: The New York Organ Donor Network (NYODN) established an Infectious Diseases Working Group (IDWG) in 2008, which established an on-call schedule of voluntary transplant infectious disease physicians to provide remote evaluations for donors at increased risk for disease transmission.
Results: Data were reviewed from 40 available IDWG evaluations from 2008 to 2011. Eighteen cases (45%) were considered to be at unacceptable risk for infection transmission. Sixteen of these cases were excluded from donation secondary to IDWG recommendation; there was limited recipient center interest in the remaining two cases. Approximately 22 (55%) cases were categorized by the IDWG as acceptable, with 14 proceeding to recovery of 49 organs. IDWG physician recommendations were conveyed to recipient centers, and screening guidelines for donors were revised based on the IDWG experiences.
Conclusion: Establishment of a donation service area disease transmission evaluation service is a valuable program for donor screening and may promote dissemination of more detailed donor information to recipient centers.

Reactivation of Trypanosoma cruzi transmission by native vectors with different domiciliation capabilities is a major concern for Chagas disease control programs. T. cruzi transmission via intra-domestic Rhodnius prolixus was certified as interrupted by the Pan American Health Organization in Miraflores municipality (Boyacá, Colombia) in 2019.

Background: The Japanese encephalitis virus (JEV), a mosquito-borne flavivirus, is known for its capacity to cause severe neurological disease in Asia. Neurotropic flaviviruses within the Japanese encephalitis (JE) serogroup possess the distinctive feature of expressing a unique nonstructural protein, NS1'. The NS1' protein consists of the full NS1 protein with an additional 52 amino acid extension at the C-terminus and has been demonstrated to exhibit virulence in mammalian hosts upon infection.

The anterior cingulate cortex (ACC) is recognized as a pivotal cortical region involved in the perception of pain. The retrosplenial cortex (RSC), located posterior to the ACC, is known to play a significant role in navigation and memory processes. Although the projections from the RSC to the ACC have been found, the specifics of the synaptic connections and the functional implications of the RSC-ACC projections remain less understood.

Whipworms (Trichuris spp) are ubiquitous parasites of humans and domestic and wild mammals that cause chronic disease, considerably impacting human and animal health. Egg hatching is a critical phase in the whipworm life cycle that marks the initiation of infection, with newly hatched larvae rapidly migrating to and invading host intestinal epithelial cells. Hatching is triggered by the host microbiota; however, the physical and chemical interactions between bacteria and whipworm eggs, as well as the bacterial and larval responses that result in the disintegration of the polar plug and larval eclosion, are not completely understood.

Background: Leishmaniasis is a health problem in many regions with poor health and poor life resources. According to the World Health Organization (WHO), an estimated 700,000-1 million new cases arise annually. Effective control of sand fly vector populations is crucial for reducing the transmission of this disease.
