Short-Term Efficacy of Using a Novel Low-Volume Bone Marrow Aspiration Technique to Treat Knee Osteoarthritis: A Retrospective Cohort Study.

Background: Intra-articular bone marrow concentrate (BMC) and aspirate (BMA) injections have been used with mixed results to treat osteoarthritis (OA). Given the various aspiration and concentration methods available for preparing bone marrow, more data are needed to identify the optimal bone marrow harvesting techniques to treat OA.

Methods: This retrospective cohort study examined the effect of using low-volume BMAs harvested using the Marrow Cellution™ (MC) device on 160 patients (262 knees) suffering from pain due to knee OA, KL grades 2-4, that did not respond to conservative treatment.

Development of a Brief Waiting Room Observation for Behaviours Typical of Reactive Attachment Disorder.

Objective:   To develop a brief standardised observational schedule for Reactive Attachment Disorder (RAD) in school-age children to aid clinician recognition of these behaviours.

Design:   A new structured observational schedule for symptoms of RAD was developed using unstructured observation of children in a clinic waiting room setting. The measure's ability to discriminate between a sample of children with RAD and a normative sample was established by comparing scores in these two groups.

The longitudinal impact of cognitive speed of processing training on driving mobility.

Purpose: To examine how cognitive speed of processing training affects driving mobility across a 3-year period among older drivers.

Design And Methods: Older drivers with poor Useful Field of View (UFOV) test performance (indicating greater risk for subsequent at-fault crashes and mobility declines) were randomly assigned to either a speed of processing training or a social and computer contact control group. Driving mobility of these 2 groups was compared with a group of older adults who did not score poorly on the UFOV test (reference group) across a 3-year period.

Reactive attachment disorder--a theoretical model beyond attachment.

Despite its importance in public health, reactive attachment disorder (RAD) is an under-researched and little used clinical category. Abnormalities of social relatedness have long been documented in children who have been abused, neglected or institutionalised, but there have been more recent efforts to define these behaviours within the psychiatric nosology. There has been an implicit assumption that the central deficit in RAD is in the attachment system, but this has caused controversy and may have blocked research.
