Pain interference impacts response to treatment for anxiety disorders

DEPRESSION AND ANXIETY, Issue 3 2009
Carrie Farmer Teh PhD
Abstract Background: Anxiety disorders and pain are commonly comorbid, though little is known about the effect of pain on the course and treatment of anxiety. Methods: This is a secondary analysis of a randomized controlled trial for anxiety treatment in primary care. Participants with panic disorder (PD) and/or generalized anxiety disorder (GAD) (N=191; 81% female, mean age 44) were randomized to either their primary-care physician's usual care or a 12-month course of telephone-based collaborative care. Anxiety severity, pain interference, health-related quality of life, health services use, and employment status were assessed at baseline, and at 2-, 4-, 8-, and 12-month follow-up. We defined response to anxiety treatment as a 40% or greater improvement from baseline on anxiety severity scales at 12-month follow-up. Results: The 39% who reported high pain interference at baseline had more severe anxiety (mean SIGH-A score: 21.8 versus 18.0, P<.001), greater limitations in activities of daily living, and more work days missed in the previous month (5.8 versus 4.0 days, P=.01) than those with low pain interference. At 12-month follow-up, high pain interference was associated with a lower likelihood of responding to anxiety treatment (OR=.28; 95% CI=.12,.63) and higher health services use (26.1% with ,1 hospitalization versus 12.0%, P<.001). Conclusions: Pain that interferes with daily activities is prevalent among primary care patients with PD/GAD and associated with more severe anxiety, worse daily functioning, higher health services use, and a lower likelihood of responding to treatment for PD/GAD.

Reformulated BeneFix®: efficacy and safety in previously treated patients with moderately severe to severe haemophilia B

HAEMOPHILIA, Issue 3 2007
T. LAMBERT
Summary. BeneFix®, the only recombinant factor IX (FIX), has been reformulated. The reformulation involves a change in diluent and allows for more concentrated infusions of recombinant FIX. A double-blind, randomized, pharmacokinetic (PK) crossover study demonstrated that reformulated BeneFix was bioequivalent to original BeneFix and follow-up PK evaluation after 6 months of treatment demonstrated the PK stability of reformulated BeneFix after multiple exposures. Favourable efficacy and safety profiles, consistent with those already well-established for original BeneFix, were observed: 81.1% of haemorrhages resolved with only a single infusion; 85.3% of initial treatment response ratings were Excellent or Good; more than half of the subjects using reformulated BeneFix for routine prophylaxis (11 of 17, 64.7%) had no spontaneous haemorrhages during their 6,12 month course of prophylactic treatment, with an overall spontaneous bleeding rate of 0.72 year,1; and for the single surgical procedure (knee washing), treatment was rated Useful. In addition, there was no FIX inhibitor development, allergic-type manifestations, or thrombogenic complications with more than 1100 infusions (nearly 5.2 million IUs) administered in this trial. All efficacy and safety outcomes from this study were achieved with more concentrated recombinant protein infusions than that possible with original BeneFix, and utilization of the 2000 IU per vial dosage strength, newly introduced with the reformulated product, was high (>62%). The reformulation of BeneFix allows smaller delivery volumes and an increased choice of dosage strengths without altering the PK properties (including incremental recovery and half-life) or the established efficacy and safety profile of recombinant FIX.

Involving users in low back pain research

HEALTH EXPECTATIONS, Issue 4 2003
Bie Nio Ong BA BEd MA PhD
Abstract Objective, To involve users in the design of a research project that aims at describing a 12-month course of low back pain in an adult population sample (epidemiological strand), and to determine how patient and professional perceptions of low back pain and its treatment relate to the use of health-care and to subsequent outcome (qualitative strand). Design, Three focus groups were organized in the preparatory phase of the project with general practitioners, other health professionals and low back pain sufferers. Issues pertaining to the experience of living with, or treating low back pain were explored and users were asked to identify relevant research questions for consideration within the study. Findings, The focus groups revealed tensions between involving users as co-researchers for design issues and their role as sufferers and health professionals who want to share their narrative accounts of low back pain. The group discussions produced a wealth of material for analysis, but no explicitly stated research topics. Three key themes and the process of user involvement in the focus groups are discussed. Conclusions, The focus group format could be restrictive in that it allows for detailed exchange between participants, but is insufficiently geared towards the production of a research agenda. We draw conclusions as to possible approaches for user involvement in health services research design. [source]

A prospective study of interferon therapy modified by pre-treatment viral load in cirrhotic patients

LIVER INTERNATIONAL, Issue 4 2000
Yasushi Shiratori
Abstract:Background/Aims: The relative role of hepatitis C virus (HCV) load and subtype as predictors of the efficacy of interferon therapy has been clarified in patients with chronic hepatitis C, but the effectiveness of interferon therapy in cirrhotic patients is still unclear. Methods: To resolve this issue, we undertook a multicenter, randomized, and prospective study of 114 cirrhotic patients with hepatitis C virus infection. The patients were selected to undergo two different periods (6 or 12 months) of IFN therapy according to viral load. Patients with "low" viral load (,105.8 copies/ml serum) were randomly divided into three groups, receiving 6 or 9 million units (MU) interferon three times a week for 6 months (total dose: 468 or 702 MU), or of a modified regimen using 6MU of IFN over 6 months (total dose 564 MU), while patients with "high" viral load (,106.3 copies/ml serum) were also randomly divided into two groups of 6 or 9 MU of IFN three times a week for 12 months (total dose: 936 or 1404 MU). Results: HCV-RNA negativity rate at the completion of treatment with 6 or 9 MU IFN was 65% in patients with "low" viral load, in contrast to 14% in patients with "high" viral load. Sustained virological response was found in 40% of patients with "low" viral load irrespective of the three different regimens, in contrast to only 1 out of 35 patients (3%) with "high" viral load. Viral eradication was found in approximately 50% of patients having a low virus load (,104.3 copies/ml) and with HCV subtype 2a. Univariate and multivariate analysis revealed that pretreatment viral load was a significant factor contributing to efficacy of IFN therapy. Conclusions: Sustained response was scarcely achieved in cirrhotic patients with high viral loads even after a 12-month course of intensive IFN therapy. This result indicates that there is a certain cut-off level of HCV RNA load which can not be eradicated. [source]

Knowledge to action: Scholarship for faculty and staff

THE JOURNAL OF CONTINUING EDUCATION IN THE HEALTH PROFESSIONS, Issue 1 2009
FAAPArticle first published online: 13 MAR 200, FRCPC, Savithiri Ratnapalan MBBS
Abstract Introduction: This study was undertaken to evaluate the influence of a continuing education course in facilitating the development and implementation of educational projects of course participants. Methods: This is a case study evaluating a full-year course that consisted of 11 monthly seminars, each 4 hours in length, including practice in a computer laboratory. The class size was limited to 12 participants. Needs-assessment surveys at the beginning of the course, student evaluations, and midterm and final progress reports were analyzed. Results: Seven staff physicians, 3 clinical fellows, a nurse educator, and a research assistant enrolled in the course. Initial needs-assessment surveys indicated that most people had adequate computer skills,11 (90%),but only 2 (17%) were able to type well, 11 (90%) had no statistical knowledge, and 10 (83%) had limited literature-searching skills. The mean score on speaker evaluations for lectures was 4.5 on a scoring scheme of 1,5 where 1 was poor and 5 was outstanding. Ten participants (83%) had a complete proposal for an educational project written by midterm. Nine participants applied for external grants and 2 of them received external funding for their projects. Five participants (42%) completed a publishable educational project by the end of the 11-month course, and submitted it for presentation at scientific meetings. Discussion: Like many adults, health care professionals experience limited time for involvement in formal education. This study shows that a limited-time-commitment course could facilitate health care professionals to develop and successfully implement educational projects translating ideas into action. [source]

Medicines information and adherence in HIV/AIDS patients

JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 1 2006
L. E. Mansoor BPharm
Summary Background:, Providing written medicines information is being legislated in an increasing number of countries worldwide, with the patient information leaflet (PIL) being the most widely used method for conveying health information. The impact of providing such information on adherence to therapy is reportedly unpredictable. Therapy for human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and related opportunistic infections usually involves polytherapy and complex regimens, both of which are risk factors for non-adherence. The objective of this study was to assess the impact of medicines information on adherence to chronic co-trimoxazole therapy in low-literate HIV/AIDS patients. Methods:, Two different PILs were designed for co-trimoxazole tablets and were available in both English and isiXhosa. Participants were randomly allocated to a control group (receiving no PIL), group A (receiving a ,complex PIL') and group B (receiving a ,simple PIL' incorporating pictograms). At the first interview, demographic data were collected and the time, date and day that the participant would take his/her first tablet of the month's course was also documented. In a follow-up interview adherence to therapy was assessed using two methods; self-report and tablet count. Results:, The medicines information materials incorporating simple text and pictograms resulted in significantly improved adherence to therapy in the short term, whereas a non-significant increase in adherence was associated with the availability of the more complex information. This was shown by both the self-reported assessment as well as the tablet count. Conclusion:, This research suggests that appropriately designed written material can have a positive impact in improving adherence and, together with verbal consultation, are essential for enabling patients to make appropriate decisions about their medicine taking.
