Description: Myelodysplastic syndrome (MDS) comprises a group of clonal bone marrow disorders characterized by ineffective hematopoiesis and increased predisposition to acute myeloid leukemia. The causes of MDS remain poorly defined, but several studies have reported the NKT cell compartment of patients with MDS is deficient in number and functionally defective. In support of a central role for NKT cells, a pilot clinical study reported that lenalidomide (an approved treatment for MDS) increased NKT cell numbers in patients with MDS, and several in vitro studies showed lenalidomide specifically promoted NKT cell proliferation and cytokine production. We tested this in a much larger study and confirm a moderate in vitro augmentation of some NKT cell functions by lenalidomide, but find no impact on the NKT cell compartment of patients treated with lenalidomide, despite a consistently positive clinical response. We further show that the frequency and cytokine production of NKT cells is normal in patients with MDS before treatment and remains stable throughout 10 months of lenalidomide therapy. Collectively, our data challenge the concept that NKT cell defects contribute to the development of MDS, and show that a clinical response to lenalidomide is not dependent on modulation of NKT cell frequency or function. © 2010 Macmillan Publishers Limited All rights reserved.

Description: Objectives: COAST (Chiropractic Observation and Analysis Study) aimed to describe the clinical practices of chiropractors in Victoria, Australia. Design: Cross-sectional study using the BEACH (Bettering the Evaluation and Care of Health) methods for general practice. Setting and participants: 180 chiropractors in active clinical practice in Victoria were randomly selected from the list of 1298 chiropractors registered on Chiropractors Registration Board of Victoria. Twenty-four chiropractors were ineligible, 72 agreed to participate, and 52 completed the study. Main outcome measures: Each participating chiropractor documented encounters with up to 100 consecutive patients. For each chiropractor-patient encounter, information collected included patient health profile, patient reasons for encounter, problems and diagnoses, and chiropractic care. Results: Data were collected on 4464 chiropractor-patient encounters from 52 chiropractors between 11 December 2010 and 28 September 2012. In most (71%) encounters, patients were aged 25-64 years; 1% of encounters were with infants (age < 1 year; 95% CI, 0.3%-3.2%). Musculoskeletal reasons for encounter were described by patients at a rate of 60 per 100 encounters (95% CI, 54-67 encounters) and maintenance and wellness or check-up reasons were described at a rate of 39 per 100 encounters (95% CI, 33-47 encounters). Back problems were managed at a rate of 62 per 100 encounters (95% CI, 55-71 encounters). The most frequent care provided by the chiropractors was spinal manipulative therapy and massage. Conclusions: A range of conditions are managed by chiropractors in Victoria, Australia, but most commonly these conditions are musculoskeletal-related. These results can be used by stakeholders of the chiropractic profession in workforce development, education and health care policy.

Description: The effectiveness of a therapist-supported Internet intervention program for tinnitus distress in an industrial setting was evaluated using a cluster randomised design. Fifty-six Australian employees of two industrial organisations were randomly assigned, based on their work site (18 work sites from BP Australia and five from BHP Billiton), to either a cognitive behavioural therapy (CBT) program or an information-only control program. Participants were assessed at pre- and postprogram, measuring tinnitus distress, depression, anxiety, stress, quality of life, and occupational health. The CBT program was not found to be superior to the information program for treating tinnitus distress. A high attrition rate and small sample size limit the generalisability of the findings, and further developments of the program and assessment process are needed to enhance engagement and compliance. © 2009 Taylor & Francis.

Description: Internet-based interventions with therapist support have proven effective for treating a range of mental health conditions. This study examined whether frequency of therapist contact affected treatment outcomes. Fifty-seven people with panic disorder (including 32 with agoraphobia) were randomly allocated to an 8-week Internet-based cognitive behavioural treatment intervention (Panic Online) with either frequent (three e-mails per week) or infrequent (one e-mail per week) support from a psychologist. Posttreatment, intention-to-treat analyses revealed that both treatments were effective at improving panic disorder and agoraphobia severity ratings, panic-related cognitions, negative affect, and psychological and physical quality of life domains, with no differences between conditions. High end-state functioning was achieved by 28.6% of the frequent and infrequent participants, respectively. Therapist alliance, treatment credibility, and satisfaction also did not differ between groups, despite significantly greater therapist time invested in the frequent contact condition. The results provide evidence that the effectiveness of Internet-based mental health interventions may be independent of the frequency of therapist support and may, therefore, be more cost-effective than previously reported. © 2009 Taylor & Francis.
