Predictive validity of obstacle-crossing test variations in identifying fallers after inpatient rehabilitation for stroke.

Background: The ability to step over an obstacle is often evaluated as part of fall-risk and balance assessments. Although different obstacle-crossing tests exist, their comparative predictive validity in stroke is unknown.

Objectives: To examine the predictive validity of different obstacle depths and different obstacle-crossing tests, including a novel, custom-height test and an existing "one-size-fits-all" obstacle test, for predicting post-stroke fallers.

Small RNA CjNC110 regulates the activated methyl cycle to enable optimal chicken colonization by .

Post-transcriptional gene regulation by non-coding small RNAs (sRNAs) is critical for colonization and survival of enteric pathogens, including the zoonotic pathogen . In this study, we utilized IA3902 (a representative isolate of the sheep abortion clone) and W7 (a highly motile variant of NCTC 11168, a human gastroenteritis strain) to further investigate regulation by sRNA CjNC110. Both motility and autoagglutination ability were confirmed to be phenotypes of conserved regulation by CjNC110.

Assessment of immunological response to digital dermatitis pathogen derived antigens following infection, recovery, and reinfection.

The ability to reliably induce bovine digital dermatitis (DD) in naive calves provides unique opportunities to evaluate immune responses of the calves to infection after disease induction, during healing, and after subsequent re-infection. Dairy calves infected in a previous induction trial were held until lesions resolved and were then re-infected in parallel with naïve calves. Humoral and cell-mediated responses were assessed via serum antibody titer and lymphocyte proliferation analysis with responses of previously infected calves compared with responses of the newly infected calves and naïve calves.

Exploring Dual-Task Performance Relationships for Veterans with Lower-Limb Amputation.

Adults with lower-limb (LL) amputation have difficulty dual-tasking which may elicit falls and is required for instrumental activities of daily living (IADLs). The purpose of this study was to explore the relationships between dual-task performance, falls, and IADLs for Veterans with LL amputation. A cross-sectional study was completed with dual-task performance, retrospective fall reporting, and participation in IADLs.
