The association between labor epidural analgesia and postpartum depression: a systematic review and meta-analysis.

BACKGROUND: Previous studies have demonstrated that appropriate treatment for postoperative pain can lead to improvement in depressive symptoms, however the association between adequate intrapartum pain control and the development of postpartum depression is not clear. The purpose of the study was to examine the effects of labor epidural analgesia and postpartum depression. METHODS: We performed a quantitative systematic review in compliance with the PRISMA statement. We conducted a search of PubMed, Embase, the Cochrane Database of Systematic Reviews and Google Scholar databases. The primary outcome was a positive screen of postpartum depression among women who received labor epidural analgesia up to 3 months into the postpartum period. Meta-analysis was performed using the random effect model. RESULTS: Of the 148 studies available, 9 studies with 4442 patients were included in the analysis. The use of labor analgesia on positive depression screen compared to control revealed no significant effect, OR (95% CI) of 1.02 (0.62 to 1.66, P = 0.94). CONCLUSION: Based on current literature, the use of epidural analgesia for pain relief during labor doesn't appear to affect the likelihood of postpartum depression. Future studies are warranted to further investigate these findings and identity other possible preventative interventions that reduce postpartum depression.

Pre-clinical Stress Management Workshops Increase Medical Students' Knowledge and Self-awareness of Coping with Stress.

OBJECTIVES: To investigate the effects of a stress management workshop on medical students' knowledge of stress and potential coping strategies. METHODS: A panel discussion with small group breakouts on stress in clinical medicine, learning challenges, competition with colleagues, handling stressful events, and recognizing burnout symptoms was conducted with medical students entering clerkships. A longitudinal survey design was utilized to measure pre-, post-, and long-term (3-month) changes in knowledge (impact of stress on personal health, learning, and patient care), confidence, perceived skills, and attitude (towards utilizing adaptive coping strategies) among participating students (N = 135). Paired t test and multivariate analyses were performed to assess the differences between survey responses on a 5-point Likert scale. RESULTS: Survey response rates were pre-90.4%, post-77%, and long-term post-71.1%. Compared to pre-workshop, students reported significant improvement in all four domains immediately post-workshop: knowledge (4.4 vs. 4.7, p < 0.05), confidence (3.6 vs. 3.9, p < 0.05), perceived skills (3.3 vs. 3.7, p < 0.05), and attitude (2.6 vs. 2.8, p < 0.05). Compared to immediate post-workshop, students' scores slightly decreased at 3 months but were overall significantly higher than the pre-workshop scores. CONCLUSIONS: A stress management workshop can improve medical students' knowledge of the impact of stress as well as the use of adaptive stress coping strategies.

Precision of lumbar intervertebral measurements: does a computer-assisted technique improve reliability?

STUDY DESIGN: Comparison of intra- and interobserver reliability of digitized manual and computer-assisted intervertebral motion measurements and classification of "instability." OBJECTIVE: To determine if computer-assisted measurement of lumbar intervertebral motion on flexion-extension radiographs improves reliability compared with digitized manual measurements. SUMMARY OF BACKGROUND DATA: Many studies have questioned the reliability of manual intervertebral measurements, although few have compared the reliability of computer-assisted and manual measurements on lumbar flexion-extension radiographs. METHODS: Intervertebral rotation, anterior-posterior (AP) translation, and change in anterior and posterior disc height were measured with a digitized manual technique by three physicians and by three other observers using computer-assisted quantitative motion analysis (QMA) software. Each observer measured 30 sets of digital flexion-extension radiographs (L1-S1) twice. Shrout-Fleiss intraclass correlation coefficients for intra- and interobserver reliabilities were computed. The stability of each level was also classified (instability defined as >4 mm AP translation or 10° rotation), and the intra- and interobserver reliabilities of the two methods were compared using adjusted percent agreement (APA). RESULTS: Intraobserver reliability intraclass correlation coefficients were substantially higher for the QMA technique THAN the digitized manual technique across all measurements: rotation 0.997 versus 0.870, AP translation 0.959 versus 0.557, change in anterior disc height 0.962 versus 0.770, and change in posterior disc height 0.951 versus 0.283. The same pattern was observed for interobserver reliability (rotation 0.962 vs. 0.693, AP translation 0.862 vs. 0.151, change in anterior disc height 0.862 vs. 0.373, and change in posterior disc height 0.730 vs. 0.300). The QMA technique was also more reliable for the classification of "instability." Intraobserver APAs ranged from 87 to 97% for QMA versus 60% to 73% for digitized manual measurements, while interobserver APAs ranged from 91% to 96% for QMA versus 57% to 63% for digitized manual measurements. CONCLUSION: The use of QMA software substantially improved the reliability of lumbar intervertebral measurements and the classification of instability based on flexion-extension radiographs.
