Outcome of electroconvulsive therapy by race in the Consortium for Research on Electroconvulsive Therapy multisite study

OBJECTIVE: The authors examine the differences in outcome between black and white patients receiving electroconvulsive therapy (ECT) as a part of the Consortium for Research on Electroconvulsive Therapy multisite study. METHODS: A total of 624 patients were enrolled in an National Institute of Mental Health (NIMH)-funded, randomized, controlled ECT trial comparing the efficacy of continuation ECT versus continuation pharmacotherapy between 1997 and 2004. This analysis focuses on the 32 black and 483 white patients who participated in phase I of the study. The authors compared baseline demographic and clinical variables and acute outcomes of these 2 groups. RESULTS: Compared with whites, far fewer blacks participated in the study. Those who did were less likely to have failed adequate medication trials and were more likely to have psychotic features. Their initial 24-item Hamilton Rating Scale for Depression scores were higher than those of the whites, and they showed a greater reduction in these 24-item Hamilton Rating Scale for Depression scores by the end of the treatment period. Although sample size limited the statistical significance of the findings, black patients also showed a higher rate of remission after an acute phase of ECT. CONCLUSIONS: This study found that black and white patients with major depressive disorder had comparable outcomes. We also found that fewer black patients received ECT than whites, a difference that has been reported in other samples.     

Focal lesions in acute mild traumatic brain injury and neurocognitive outcome: CT versus 3T MRI

Abstract Mild traumatic brain injury (mTBI) is associated with long-term cognitive deficits. This study compared the detection rate of acute post-traumatic focal lesions on computed tomography (CT) and 3T (Tesla) magnetic resonance (MR) imaging with neurocognitive outcomes. Adults (n = 36; age range, 19-52 years) with a single episode of mTBI (Glasgow Coma Scale 13-15, as well as loss of consciousness and post-traumatic amnesia) were prospectively enrolled and had CT within 24 h of injury and 3T MR within 2 weeks of injury. The CT and MR scans were reviewed by two neuroradiologists who were blinded to clinical information. Twenty-eight of these mTBI subjects and 18 matched healthy volunteers also underwent serial neurocognitive testing. Of the 36 mTBI cases, intraparenchymal lesions were detected in 18 CT and 27 acute MR exams, consisting of hemorrhagic traumatic axonal injury (TAI) (eight CT, 17 MR), non-hemorrhagic TAI (zero CT, four MR), and cerebral contusions (13 CT, 21 MR). Mild TBI patients had significantly worse performance on working memory tasks than matched controls at the acute time point (<2 weeks), and at 1 month and at 1 year post-injury; yet there was no significant correlation of imaging findings with working memory impairment. In conclusion, 3T MR detected parenchymal lesions in 75% of this mTBI cohort with loss of consciousness and post-traumatic amnesia, a much higher rate than CT. However, the CT and 3T MR imaging findings did not account for cognitive impairment, suggesting that newer imaging techniques such as diffusion tensor imaging are needed to provide biomarkers for neurocognitive and functional outcome in mTBI.     

Microcirculation in sepsis and septic shock - therapeutic options?

In severe sepsis and septic shock the severe impairment of the microcirculation is one of the main reasons for tissue hypoxia, multiple organ failure and death. Fast resuscitation of the microvascular blood flow to improve the reduced functional capillary density is necessary. Based scientific evidence, an early haemodynamic stabilisation directed by predefined haemodynamic and metabolic goals and the application of activated protein C (rhAPC) according to the guidelines could be recommended. The specific effects of dobutamine and rhAPC on the microcirculation as well as the effects selective inhibitors of iNOS or vasodilators may be therapeutic options in the future.     

The ‘M2 DASH’—Manchester-Modified Disabilities of Arm Shoulder and Hand Score

The Disability of the Arm, Shoulder, and Hand (DASH) questionnaire was originally designed as a measure of disability in patients with disorders of the upper limb, but the DASH score is also affected by disability because of lower limb disorders. The aim of this study was to investigate the construct validity of the DASH questionnaire and to create a revised DASH questionnaire, the Manchester-modified or M² DASH, with fewer questions that is more specific to the upper limb. Patients were asked to fill in the DASH questionnaire in a fracture clinic after ethical approval. This included 79 patients with upper limb injuries, 61 patients with lower limb injuries, and 52 control subjects. The mean DASH scores for the three groups varied significantly, and the lower limb group had a mean score of 16. The M² DASH questionnaire was developed using questions more specific to the upper limb and included questions 1–4, 6, 13–17, 21–23, and 26–30 from the original questionnaire. The mean M² DASH score for the lower limb group was 9 and, unlike the original DASH score, was not statistically different from the control group. The M² DASH scores were then calculated for the upper limb group and a correlation study showed highly significant correlation between the original DASH scores and the M² DASH scores. Our study shows that the original DASH questionnaire is not specific for the upper limb. The M² DASH questionnaire has the advantage of being more specific for the upper limb than the DASH questionnaire, and it correlates well with the original DASH questionnaire when looking at isolated upper limb injuries.     

Long-term effects on diet after proctocolectomy for ulcerative colitis

BACKGROUND: Patients with ulcerative colitis (UC) often report dietary intolerances. Our aim was to assess the effects of proctocolectomy (PC) for UC on dietary intolerances. METHODS: A novel disease-specific questionnaire was used. RESULTS: Eighty-seven percent of patients reported 338 dietary intolerances. Of 225 preoperative dietary intolerances, 151 (67%) resolved/improved, 56 (25%) were unchanged, and 18 (8%) were exacerbated after PC. A total of 113 dietary intolerances developed only after PC. The incidence of specific dietary intolerances in patients 10 years and older post-PC was similar to patients younger than 10 years post-PC except for a lower incidence of caffeinated beverage (P = .01) dietary intolerances 10 years or more post-PC. Intestinal symptoms, bowel function, and activities of daily living largely improved after PC. Extraintestinal UC symptoms worsened or failed to improve in 74%. CONCLUSIONS: PC for UC frequently improves preoperative dietary intolerances. Some patients, however, are at risk for onset of new dietary intolerances after PC. Studies examining traditional symptoms in UC patients pre-PC and post-PC may be enhanced by examining effects on specific dietary intolerances.     

The importance of the disease process and disease-modifying antirheumatic drug treatment in the development of septic arthritis in patients with rheumatoid arthritis

OBJECTIVE: To evaluate the effect of disease-modifying antirheumatic drugs (DMARDs) on the likelihood of patients with rheumatoid arthritis (RA) developing septic arthritis (SA). METHODS: The United Kingdom General Practice Research Database (GPRD) was used to identify adults with RA, and age-, sex-, and practice-matched control subjects. Subjects were studied between 1987 and 2002. The risk of developing SA (excluding infected joint replacements) for individuals with RA was calculated and the effect of DMARD use determined. RESULTS: A total of 136,977 subjects (34,250 patients with RA, 102,747 controls) were identified. SA was identified in 345 subjects, of which 321 (236 in patients with RA, 85 in controls) cases occurred during the study period. The incidence rate of SA was 12.9 times higher in subjects with RA than in those without (95% confidence interval [95% CI] 10.1-16.5, P < 0.001). The incident rate ratios (IRRs) for developing SA while receiving DMARDs compared with receiving no DMARDs were different for different medications. Penicillamine (adjusted IRR 2.51, 95% CI 1.29-4.89, P = 0.004), sulfasalazine (adjusted IRR 1.74, 95% CI 1.04-2.91, P = 0.03), and prednisolone (adjusted IRR 2.94, 95% CI 1.93-4.46, P < 0.001) were associated with an increased incidence of SA when compared with not receiving any DMARD. The use of other DMARDs including methotrexate showed no such effect. CONCLUSION: Individuals with RA have an increased risk of developing SA. This increased risk can be attributed to both the disease process and the use of DMARDs.     

Early identification of radiographic osteoarthritis of the hip using an active shape model to quantify changes in bone morphometric features: can hip shape tell us anything about the progression of osteoarthritis?

OBJECTIVE: Few methods exist to measure the progression of osteoarthritis (OA) or to identify people at high risk of developing OA. Striking radiographic changes include deformation of the femoral head and osteophyte growth, which are usually measured semiquantitatively following visual assessment. In this study, an active shape model (ASM) of the proximal femur was used to determine whether morphologic changes to the bone could be quantified and used as a marker of hip OA. METHODS: One hundred ten subjects who had no signs of radiographic hip OA at baseline (Kellgren/Lawrence [K/L] scores 0-1) were selected from the Rotterdam Study cohort of subjects ages > or = 55 years. To measure the progression of OA, subjects were followed up with radiographic assessment after 6 years. At the 6-year followup, 55 subjects had established OA (K/L score 3), and in 12 of these OA subjects, the progression of the disease required a total hip replacement (THR). Age- and sex-matched control subjects had a K/L score of 0 at followup. Using the ASM, subjects were assessed for shape changes in the femoral head and neck before, during, and after the development of radiographic OA. Scores of shape variance, or mode scores, were assigned for 10 modes of variation in each subject, and differences in mode scores were determined. RESULTS: During followup, significant changes in shape of the proximal femur occurred within the OA group from baseline to followup (P < 0.0001 for mode 1 and P = 0.002 for mode 6) but not within the control group. At baseline (all subjects having K/L scores 0-1), there were significant differences in mode 6 between the OA group and the control group (P = 0.020), and in modes 3 and 6 between the OA subjects who underwent THR and the remaining OA subjects (P = 0.012 and P = 0.019, respectively). CONCLUSION: Compared with traditional scoring methods, the ASM can be used more precisely to quantify the deforming effect of OA on the proximal femur and to identify, at an earlier stage of disease, those subjects at highest risk of developing radiographic OA or needing a THR. The ASM may therefore be useful as an imaging biomarker in the assessment of patients with hip OA.
