Exercise parameters in the treatment of clinical depression: a systematic review of randomized controlled trials

JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 3 2010
Luke G. Perraton BPT MPT
Abstract Rationale, aims and objectives, Previous systematic reviews have concluded that exercise programmes are effective in the management of clinical depression. The aim of this review was to analyse the parameters of exercise programmes reported in the primary research, in order to provide clinicians with evidence-based recommendations for exercise prescription for clinical depression. Methods, A systematic review of randomized controlled trials was undertaken. Only trials that reported exercise to be effective in treating depression were included and our review was limited to adults. Appropriate databases and reference lists were searched using established keywords. Data relating to the type, intensity, frequency, duration, mode of exercise and mode of application of exercise was extracted and collated. Results, A total of 14 randomized controlled trials were included in this review and from these trials 20 intervention arms were analysed. The majority of trials used an aerobic exercise intervention and were supervised. The most common exercise parameters were 60,80% of maximum heart rate for 30 minutes three times per week for an overall duration of 8 weeks. There is an equal volume of evidence supporting group as opposed to individually completed exercise programmes and no trends were identified which would support one mode of exercise over another. Conclusions, Currently the primary research on this topic supports the use of aerobic exercise which is supervised in some capacity. The current evidence base supports a prescription of three 30-minute sessions per week of aerobic exercise at 60,80% of maximum heart rate for at least 8 weeks. [source]


Lack of evidence of the effectiveness of primary brachial plexus surgery for infants (under the age of two years) diagnosed with obstetric brachial plexus palsy

Abstract Background, Obstetric brachial plexus palsy, which occurs in 1,3 per 1000 live births, results from traction and/or compression of the brachial plexus in utero, during descent through the birth canal or during delivery. This results in a spectrum of injuries that range in extent of damage and severity and can lead to a lifelong impairment and functional difficulties associated with the use of the affected upper limb. Most infants diagnosed with obstetric brachial plexus palsy receive treatment, such as surgery to the brachial plexus, physiotherapy or occupational therapy, within the first months of life. However, there is controversy regarding the most effective form of management. This review follows on from our previous systematic review which investigated the effectiveness of primary conservative management in infants with obstetric brachial plexus palsy. This systematic review focuses on the effects of primary surgery. Objectives, The objective of this review was to systematically assess and collate all available evidence on effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Search strategy, A systematic literature search was performed using 13 databases: TRIP, MEDLINE, CINAHL, Web of Science, Proquest 5000, Evidence Based Medicine Reviews, Expanded Academic ASAP, Meditext, Science Direct, the Physiotherapy Evidence Database, Proquest Digital Dissertations, Open Archives Initiative Search Engine, the Australian Digital Thesis program. Those studies that were reported in English and published between July 1992 to June 2004 were included in this review. Selection criteria, Quantitative studies that investigated the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy were eligible for inclusion into this review. This excluded studies where infants were solely managed conservatively or with pharmacological agents, or underwent surgery for the management of secondary deformities. Data collection and analysis, Two independent reviewers assessed the eligibility of each study for inclusion into the review, the study design used and its methodological quality. Where any disagreement occurred, consensus was reached by discussion. Studies were also assessed for clinical homogeneity by considering populations, interventions and outcomes. Where heterogeneity was present, synthesis was undertaken in a narrative format. Results, Twenty-one studies were included in the review. Most were ranked low on the hierarchy of evidence (no randomised controlled trials were found), and most had only fair methodological quality. Surgical intervention was variable, as were the eligibility criteria for surgery, the timing of surgery and the outcome instruments used to evaluate the effect of surgery. Therefore, it is difficult to draw conclusions regarding the effectiveness of primary brachial plexus surgery for infants with obstetric brachial plexus palsy. Conclusions, Although there is a wealth of information regarding the outcome following primary brachial plexus surgery it was not possible to determine whether this treatment is effective in increasing functional recovery in infants with obstetric brachial plexus palsy. Further research is required to develop standardised surgical criteria, and standardised outcome measures should be used at specific points in time during the recovery process to facilitate comparison between studies. Moreover, comparison groups are required to determine the relative effectiveness of surgery compared with other forms of management. [source]


Anxiety does not predict response to antidepressant treatment in late life depression: results of a meta-analysis

INTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 5 2009
J. Craig Nelson
Abstract Objective Previous studies of mixed aged and older adult samples with major depressive disorder (MDD) reported reduced depression response in anxious patients, but a systematic review and analysis has not been performed. Our aim was to determine if anxiety predicts antidepressant response in previously identified placebo-controlled trials of second generation antidepressants for late-life depression. Method From a previous systematic review that identified ten randomized, placebo-controlled trials of community dwelling patients aged 60 or older with major depression, anxious patients were identified by a score ,7 on the anxiety/somatization factor of the Hamilton Depression Rating Scale (HDRS). Response was defined as 50% or greater improvement on the HDRS or the Montgomery Asberg Depression Rating Scale. A meta-analysis was performed using a random effects model to calculate Odds Ratios (OR). Results Data were available from eight trials having ten drug-placebo contrasts that included 2322 anxious and 1387 non-anxious patients. The odds ratio for response to drug compared to placebo in anxious patients was 1.57 (95% CI 1.15, 2.14; z,=,2.86, n,=,10, p,<,0.001), in non-anxious patients was 1.44 (95% CI 1.15, 1.80, z,=,3.21, n,=,10, p,<,0.001), and did not differ between groups. Pooled response rates to drug and placebo respectively were 49.4% vs 37.4% in anxious patients and 44.2 vs 35.5% in non-anxious patients. Conclusions In randomized, placebo-controlled trials, anxiety in late-life depression was not associated with decreased response to second generation antidepressants.

Tensions and Paradoxes in Electronic Patient Record Research: A Systematic Literature Review Using the Meta-narrative Method

THE MILBANK QUARTERLY, Issue 4 2009
TRISHA GREENHALGH
Context: The extensive research literature on electronic patient records (EPRs) presents challenges to systematic reviewers because it covers multiple research traditions with different underlying philosophical assumptions and methodological approaches. Methods: Using the meta-narrative method and searching beyond the Medline-indexed literature, this review used "conflicting" findings to address higher-order questions about how researchers had differently conceptualized and studied the EPR and its implementation. Findings: Twenty-four previous systematic reviews and ninety-four further primary studies were considered. Key tensions in the literature centered on (1) the EPR ("container" or "itinerary"); (2) the EPR user ("information-processer" or "member of socio-technical network"); (3) organizational context ("the setting within which the EPR is implemented" or "the EPR-in-use"); (4) clinical work ("decision making" or "situated practice"); (5) the process of change ("the logic of determinism" or "the logic of opposition"); (6) implementation success ("objectively defined" or "socially negotiated"); and (7) complexity and scale ("the bigger the better" or "small is beautiful"). Conclusions: The findings suggest that EPR use will always require human input to recontextualize knowledge; that even though secondary work (audit, research, billing) may be made more efficient by the EPR, primary clinical work may be made less efficient; that paper may offer a unique degree of ecological flexibility; and that smaller EPR systems may sometimes be more efficient and effective than larger ones. We suggest an agenda for further research. [source]


Meta-analysis using individual patient data from randomised trials to assess the effectiveness of laparoscopic uterosacral nerve ablation in the treatment of chronic pelvic pain: a proposed protocol

BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 12 2007

Background, Currently, there are a number of clinical trials, but no international collaboration for collating research on effectiveness of laparoscopic uterosacral nerve ablation (LUNA) for alleviating chronic pelvic pain. Objective, Meta-analysis was used by collecting individual patient data (IPD) from the existing trials, to provide a comprehensive assessment of the effectiveness of LUNA that will be generalisable in various clinical contexts. Methods, IPD will be sought and collected from all relevant (both already finished and continuing) randomised trials identified through previous systematic reviews. After obtaining raw data and cleaning the database, analysis will be of all patients ever randomised based on the intention-to-treat principle using endpoints measured at 12 months following randomisation. Proposal, We will update searches, contact all authors, obtain data in whatever form it can be provided, build a single database, produce results for individual studies, have them verified by original authors, explore of any heterogeneity and reasons behind it and finally pool all raw data in to a meta-analysis using appropriate statistical methods. The project will test the effectiveness of LUNA for women with chronic pelvic pain. It will also motivate collaborating primary investigators to undertake new primary studies to corroborate or improve upon the conclusions derived from the retrospective analysis. [source]
