Perspectives on improving wound care for Aboriginal health workers in rural and remote communities in Queensland, Australia.

Background: The care of wounds is an ongoing issue for Indigenous people worldwide, yet culturally safe Indigenous wound care training programs for rural and remote Australian Aboriginal Health Workers are largely unavailable. The higher prevalence of chronic disease, lower socioeconomic status and poorer access to services experienced by Aboriginal and Torres Strait Islanders compared to non-Indigenous people, leads to a greater incidence of chronic wounds in Aboriginal and Torres Strait Islander people. Identifying the barriers and enablers for delivering wound care will establish areas of need for facilitating the development of a specific wound care program for Aboriginal Health Workers and Aboriginal Health Practitioners.

Acoustic properties of vocal singing in prelingually-deafened children with cochlear implants or hearing aids.

Objective: The purpose of the present study was to investigate vocal singing performance of hearing-impaired children with cochlear implants (CI) and hearing aids (HA) as well as to evaluate the relationship between demographic factors of those hearing-impaired children and their singing ability.

Methods: Thirty-seven prelingually-deafened children with CIs and 31 prelingually-deafened children with HAs, and 37 normal-hearing (NH) children participated in the study. The fundamental frequencies (F0) of each note in the recorded songs were extracted and the duration of each sung note was measured.

Rapid DNA sequencing based upon single molecule detection.

We are developing a laser-based technique for the rapid sequencing of 40-kb or larger fragments of DNA at a rate of 100 to 1000 bases per second. The approach relies on fluorescent labeling of the bases in a single fragment of DNA, attachment of this labeled DNA fragment to a support, movement of the supported DNA fragment into a flowing sample stream, and detection of individual fluorescently labeled bases as they are cleaved from the DNA fragment by an exonuclease. The ability to sequence large fragments of DNA will significantly reduce the amount of subcloning and the number of overlapping sequences required to assemble megabase segments of sequence information.
