The Magpie Trial: a randomised trial comparing magnesium sulphate with placebo for pre-eclampsia. Outcome for children at 18 months

To assess the long-term effects of in utero exposure to magnesium sulphate for children whose mothers had pre-eclampsia.



Assessment at 18 months of age for children whose mothers were recruited to the Magpie Trial (recruitment 1998-2001 ISRCTN 86938761), which compared magnesium sulphate with placebo.



Follow-up of children born at 125 centres in 19 countries across five continents.



A total of 6922 children were born to women randomised before delivery at follow-up centres. Of these, 2271 were not included for logistic reasons and 168 were excluded (101 at a centre where <20% were contacted, 40 whose death or disability was due to a problem at conception or embryogenesis and 27 whose parent/s opted out). Therefore, 4483 children were included in follow-up, of whom 3283 (73%) were contacted.



Assessment by questionnaire, with interview and neurodevelopmental testing of selected children.



Death or neurosensory disability at age of 18 months.



Of those allocated magnesium sulphate, 245/1635 (15.0%) were dead or had neurosensory disability at 18 months compared with 233/1648 (14.1%) allocated placebo (relative risk [RR] 1.06, 95% CI 0.90-1.25), and of survivors, 19/1409 (1.3%) had neurosensory disability at 18 months compared with 27/1442 (1.9%) (RR 0.72, 95% CI 0.40-1.29). There were no substantial differences in causes of death or in the risk of individual impairments or disabilities.



The lower risk of eclampsia following prophylaxis with magnesium sulphate was not associated with a clear difference in the risk of death or disability for children at 18 months.
Chronic motor dysfunction after stroke: recovering wrist and finger extension by electromyography-triggered neuromuscular stimulation.

After stroke, many individuals have chronic unilateral motor dysfunction in the upper extremity that severely limits their functional movement control. The purpose of this study was to determine the effect of electromyography-triggered neuromuscular electrical stimulation on the wrist and finger extension muscles in individuals who had a stroke > or = 1 year earlier.



Eleven individuals volunteered to participate and were randomly assigned to either the electromyography-triggered neuromuscular stimulation experimental group (7 subjects) or the control group (4 subjects). After completing a pretest involving 5 motor capability tests, the poststroke subjects completed 12 treatment sessions (30 minutes each) according to group assignments. Once the control subjects completed 12 sessions attempting wrist and finger extension without any external assistance and were posttested, they were then given 12 sessions of the rehabilitation treatment.



The Box and Block test and the force-generation task (sustained muscular contraction) revealed significant findings (P<0. 05). The experimental group moved significantly more blocks and displayed a higher isometric force impulse after the rehabilitation treatment.



Two lines of evidence clearly support the use of the electromyography-triggered neuromuscular electrical stimulation treatment to rehabilitate wrist and finger extension movements of hemiparetic individuals > or =1 year after stroke. The treatment program decreased motor dysfunction and improved the motor capabilities in this group of poststroke individuals.
Reliability of the Community Balance and Mobility Scale (CB&M) in high-functioning school-aged children and adolescents who have an acquired brain injury.

To examine inter-rater, intra-rater and test-re-test reliability of the Community Balance and Mobility Scale (CB&M) and compare reliability in live vs videotape rating contexts for children with acquired brain injury (ABI).



Repeated measures design.



Seven physiotherapists (PTs) were trained as assessors. The primary assessor administered and scored baseline CB&M while the second assessor observed and scored independently (inter-rater reliability). Re-assessment occurred 3-10 days later by primary assessor (test-re-test reliability). Assessments were videotaped.



There were 32 participants with ABI (mean age = 14 years 1 month (SD = 2 years 1 month)). Baseline mean scores were 67.4% (18.2) and 66.7% (18.3) for primary and second assessor, respectively. Primary assessors' re-test mean score was 69.3%. Inter-rater reliability ICC was 0.93 (95% confidence interval (CI) = 0.87-0.97). Test-re-test ICC was 0.90 (95%CI = 0.81-0.95) and Bland-Altman plot indicated greatest test-re-test differences for mid-range CB&M scores. Minimum detectable change (MDC₉₀) was 13.5% points.



The CB&M showed excellent reliability in youth. Reliability was comparable for live and videotape rating approaches, meaning that the easier and less expensive live-rating can be recommended. Future work should focus on evaluation of responsiveness to change in rehabilitation centre and community intervention contexts.
Admission, discharge, or change in B-type natriuretic peptide and long-term outcomes: data from Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF) linked to Medicare claims.

B-type natriuretic peptide (BNP) has been associated with short- and long-term postdischarge prognosis among hospitalized patients with heart failure. It is unknown if admission, discharge, or change from admission to discharge BNP measure is the most important predictor of long-term outcomes.



We linked patients ≥65 years of age from hospitals in Organized Program to Initiate Lifesaving Treatment in Hospitalized Patients with Heart Failure (OPTIMIZE-HF) to Medicare claims. Among patients with recorded admission and discharge BNP, we compared Cox models predicting 1-year mortality and/or rehospitalization, including clinical variables and clinical variables plus BNP. We calculated the net reclassification improvement (NRI) and integrated discrimination improvement (IDI) for the best-fit model for each outcome versus the model with clinical variables alone. Among 7039 patients in 220 hospitals, median (25th, 75th) admission and discharge BNP were 832 pg/mL (451, 1660) and 534 pg/mL (281, 1111). Observed 1-year mortality and 1-year mortality or rehospitalization rates were 35.2% and 79.4%. The discharge BNP model had the best performance and was the most important characteristic for predicting 1-year mortality (hazard ratio for log transformation, 1.34; 95% confidence interval, 1.28 to 1.40) and 1-year death or rehospitalization (hazard ratio, 1.15; 95% confidence interval, 1.12 to 1.18). Compared with a clinical variables only model, the discharge BNP model improved risk reclassification and discrimination in predicting each outcome (1-year mortality: NRI, 5.5%, P<0.0001; IDI, 0.023, P<0.0001; 1-year mortality or rehospitalization: NRI, 4.2%, P<0.0001; IDI, 0.010, P<0.0001).



Discharge BNP best predicts 1-year mortality and/or rehospitalization among older patients hospitalized with heart failure. Discharge BNP plus clinical variables modestly improves risk classification and model discrimination for long-term outcomes.
THE UNIVERSITY OF FLORIDA.

The purpose of this course is for students to develop a working knowledge of the influence of health disparities on health outcomes among vulnerable populations in the United States and the role of health policy. The course will begin with an introduction to the concept of vulnerability and a vulnerability framework for research. Next, we will cover social, individual, and systematic influences on health and vulnerability. Finally, students will learn about interventions and policies aimed at reducing health disparities in vulnerable populations.
A double blind randomized active-controlled clinical trial on the intra-articular use of Md-Knee versus sodium hyaluronate in patients with knee osteoarthritis ("Joint").

To evaluate the clinical outcomes of a group of patients affected by knee osteoarthritis (OA) treated with MD-Knee (Guna S.p.a., Milan, Italy) versus a group of patients treated with sodium hyaluronate.



This non-inferiority prospective randomized controlled trial involved 60 patients affected by knee OA, grade 2-3 of Kellgren-Lawrence scale. The MD-Knee Group, Group A (n = 29) was administered five intra-articular injections at 1 week interval; the sodium hyaluronate Group, Group B (n = 31), was administered five doses of intra-articular injection of sodium hyaluronate at 1 week interval. All patients were prospectively evaluated before and at 3 and 6 months after the treatment by the Lequesne Knee Index (LKI) as primary endpoint and the Visual Analogue Scale (VAS), Pain Killer consumption and SF-36 questionnaires as secondary endpoints.



At the 3- and 6 month follow-up, LKI and VAS improved significantly in both groups compared to baseline and no statistically significant differences were observed between Group A and Group B. There was no statistically significant difference in the SF36 questionnaire score and pain killer consumption between two groups at any time point.



This study shows that both preparations exert similar clinical effects as assessed through multiple outcome measures. MD-Knee is effective on knee OA symptoms over 6 months after a 5-weekly injection course, and it is equally effective as the reference sodium hyaluronate.
Therapeutic strategies in rheumatoid arthritis over a 40-year period.

To examine trends in therapeutic strategies and to identify the determinants of starting disease modifying antirheumatic drug (DMARD) therapy over a 40-year period in a population based inception cohort of patients with rheumatoid arthritis (RA).



A population based inception cohort was assembled from among all Rochester, Minnesota, residents aged > or = 18 years who were first diagnosed with RA (1987 American College of Rheumatology criteria) between January 1, 1955, and January 1, 1995. All subjects were followed longitudinally through their complete medical records until death, migration from Olmsted County, or date of abstraction (January 1, 2001, to January 1, 2003). Drug exposure data were collected on all DMARD and corticosteroid regimens. Time to DMARD initiation was examined using the Kaplan-Meier method. The influence of calendar time and disease characteristics on time from incidence to first DMARD therapy and the number of DMARD regimens were analyzed using Cox regression and proportional odds models, respectively.



The study population comprised 603 patients (73% female) with a mean age of 58 years and a mean followup of 15 years. At 2 years after RA onset, 26% of patients in the 1955-74 cohort, 40% in the 1975-84 cohort, and 70% in the 1985-94 cohort had received a DMARD (log-rank p < 0.001). Age, rheumatoid factor (RF) positivity, erythrocyte sedimentation rate, large joint swelling, rheumatoid nodules, and destructive changes on radiographs were significantly associated with time to first DMARD regimen after adjustment for calendar time and sex. Patients who were older and RF positive and who did not receive CS were more likely to have received more DMARD regimens.



Time to initiation of DMARD therapy has shortened markedly over the past 3-4 decades. These changes in management of early RA provide evidence for the translation of scientific evidence into clinical practice in rheumatology. Age and various disease characteristics are significantly associated with initiation and the number of DMARD regimens used. These should be considered as confounders when examining the effect of early DMARD treatment on disease progression and mortality.
Effectiveness of the physical therapy Godelive Denys-Struyf method for nonspecific low back pain: primary care randomized control trial.

A simple blind, random controlled clinical trial.



To assess the effectiveness of physiotherapy treatment based on the muscular and articular chains Godelive Denys-Struyf (GDS) method for nonspecific low back pain (LBP) in primary care.



Despite a systematic review by the European COST ACTION B13 "Low back pain: guidelines for its management," there are still many unresolved questions regarding the effectiveness of the different physical therapy treatments used for LBP.



21 physicians and physiotherapists in 7 Primary Care Centers and 6 researches in the Complutense University of Madrid (Spain).



137 patients diagnosed with nonspecific LBP.



The control group underwent 15 sessions of conventional physiotherapy in Primary Care Centers, and the experimental group received 15 GDS treatment sessions. Pain was evaluated by Visual Analogical Scale (VAS), functional disability by Oswestry questionnaire, and quality of life by the physical and mental components of SF-36 questionnaire. Outcome measures were assessed before treatment (A1), at the end of treatment (A2), and at 3 months (A3), and 6 months (A4) of follow-up.



Repeated measures analysis of variance revealed that at the end of treatment and 3 months later, subjects in both groups showed less pain, reduced functional disability, and an improved quality of life, though improvements were greater in the GDS group.Six months after treatment, patients in the GDS group continued to show reduced pain (VAS(A4-A1) = -3.54, 95% CI: -4.18 to -2.90) while VAS scores in the control group returned to initial values (VAS(A4-A1) = 0.15, 95% CI: -0.36 to 0.67).



Treatment of nonspecific LBP using the GDS method provides greater improvements in the midterm (6 months) in terms of the pain, functional ability, and quality of life perceived by patients than the conventional treatment based administered in primary care.
Angiotensin II receptor type 1 gene expression in human glomerulonephritis and diabetes mellitus.

The renin-angiotensin system plays an important role in the progression of chronic renal disease. Although the expression of renin and angiotensin-converting enzyme in experimental and human renal disease has been well characterized, no information is available regarding human angiotensin type 1 (AT1) receptor expression. The net effect of renin depends on AT1 receptor expression, among other factors. Receptor expression was determined in renal biopsy samples (including all tissue components) and isolated glomeruli from patients with glomerulonephritis (GN) or diabetic nephropathy (non-insulin-dependent diabetes mellitus). Biopsy samples and isolated glomeruli from tumor-free tissue from tumor nephrectomies served as controls. Human AT1 receptor gene expression was determined by quantitative reverse transcription-PCR, using an AT1 receptor deletion mutant as the internal standard. In whole biopsy samples from 37 patients with various types of GN, AT1 receptor mRNA levels were lower, compared with nine control biopsy samples (P < 0.001). AT1 receptor mRNA levels were also significantly lower (P < 0.001) in eight samples from patients with diabetic nephropathy. In microdissected glomeruli, AT1 receptor gene expression was significantly lower in samples from patients (n = 22) with various types of GN, compared with 12 microdissected tumor nephrectomy control samples (P < 0.0023). It is concluded that AT1 receptor mRNA expression is low in glomeruli of patients with chronic renal disease. This may reflect a regulatory response to (inappropriately) high intrarenal angiotensin II concentrations.
Sexual behaviour and HIV infection in black-Africans in England: results from the Mayisha II survey of sexual attitudes and lifestyles.

To estimate HIV prevalence and the distribution of high risk sexual behaviours, sexual health service use, and HIV testing among black Africans aged 16 years or over in England. To determine demographic, behavioural and service use factors associated with HIV prevalence.



A cross-sectional community-based survey (Mayisha II) in London, Luton and the West Midlands. A short (24-item) anonymous self-completion questionnaire with linked voluntary anonymous oral fluid sampling, using an Orasure device for HIV testing.



A total of 1359 eligible black African men (51.9%) and women (48.1%) were recruited, of whom 74% (1006) provided a sufficient oral fluid sample for HIV testing. 42.9% of men and 50.9% of women reported ever having had an HIV test. Overall, 14.0% (141, 95% CI 11.9 to 16.3) of respondents tested HIV positive (13.1% of men and 15.0% of women); 9.2% (93) had undiagnosed HIV infection, while 4.8% (48) had a diagnosed HIV infection. HIV prevalence was significantly higher in men: born in East Africa; who had had a previous STI diagnosis; or who were recruited in bars and clubs; and in women: born in East or Southern Africa; aged 25 years and over; who had had two new sexual partners in the past 12 months; or who had had a previous STI diagnosis.



Despite about half the sample having had an HIV test at some time in the past, 9.2% of respondents had an undiagnosed HIV infection. This study supports current policy efforts to further promote HIV testing and serostatus awareness.
Accuracy of diagnosing gastroesophageal reflux disease by GerdQ, esophageal impedance monitoring and histology.

To assess the performance of self-assessment gastroesophageal reflux disease questionnaire (GerdQ), 24-h impedance monitoring, proton pump inhibitor (PPI) test and intercellular space of esophageal mucosal epithelial cells in the diagnosis of gastroesophageal reflux disease (GERD).



Patients with symptoms suspected of GERD were administered the GerdQ and underwent endoscopy (measurement of intercellular space in the biopsy specimen sampling at 2 cm above the Z-line) and 24-h impedance pH monitoring, together with a 2-week experimental treatment with esomeprazole.



A total of 636 patients were included for the final analysis, including 352 with GERD. The sensitivity and specificity of GerdQ and 24-h impedance monitoring for diagnosing GERD were 57.7% and 48.9%, and 66.4% and 43.3%, respectively. The sensitivity of 24-h impedance pH monitoring increased to 93.7%. The sensitivity and specificity of dilated intercellular spaces (DIS) (≥0.9 μm) for diagnosing GERD were 61.2% and 56.1%, respectively, whereas those for PPI test were 70.5% and 44.4%.



GerdQ score or PPI test alone cannot accurately diagnose GERD in a Chinese population suspected of GERD. A definitive diagnosis of GERD still depends on endoscopy or 24-h pH monitoring. 24-h impedance pH monitoring may increase the sensitivity for diagnosing GERD by 20%; however, when used alone, it results in poor specificity in patients without acid suppressive therapy.
Treatment of abdominal compartment syndrome in severe acute pancreatitis patients with traditional Chinese medicine.

To investigate the therapeutic effect of traditional Chinese traditional medicines Da Cheng Qi Decoction (Timely-Purging and Yin-Preserving Decoction) and Glauber's salt combined with conservative measures on abdominal compartment syndrome (ACS) in severe acute pancreatitis (SAP) patients.



Eighty consecutive SAP patients, admitted for routine non-operative conservative treatment, were randomly divided into study group and control group (40 patients in each group). Patients in the study group received Da Cheng Qi Decoction enema for 2 h and external use of Glauber's salt, once a day for 7 d. Patients in the control group received normal saline (NS) enema. Routine non-operative conservative treatments included non-per os nutrition (NPON), gastrointestinal decompression, life support, total parenteral nutrition (TPN), continuous peripancreatic vascular pharmaceutical infusion and drug therapy. Intra-cystic pressure (ICP) of the two groups was measured during treatment. The effectiveness and outcomes of treatment were observed and APACHE II scores were applied in analysis.



On days 4 and 5 of treatment, the ICP was lower in the study group than in the control group (P < 0.05). On days 3-5 of treatment, acute physiology and chronic health evaluation II (APACHE II) scores for the study and control groups were significantly different (P < 0.05). Both the effectiveness and outcome of the treatment with Da Cheng Qi Decoction on abdominalgia, burbulence relief time, ascites quantity, cyst formation rate and hospitalization time were quite different between the two groups (P < 0.05). The mortality rate for the two groups had no significant difference.



Da Cheng Qi Decoction enema and external use of Glauber's salt combined with routine non-operative conservative treatment can decrease the intra-abdominal pressure (IAP) of SAP patients and have preventive and therapeutic effects on abdominal compartment syndrome of SAP.
Prostate specific antigen decrease and prostate cancer diagnosis: antibiotic versus placebo prospective randomized clinical trial.

Prostate inflammation can lead to an increase in serum prostate specific antigen concentration and confound the use of prostate specific antigen kinetics. Repeat prostate specific antigen measurements after a period of observation or a course of empirical antibiotics are controversial in terms of the optimal approach to reduce the confounding impact on prostate cancer screening. This issue was analyzed in patients with a diagnosis of type IV or asymptomatic prostatitis (National Institutes of Health classification) and high prostate specific antigen.



We studied 200 men between 50 and 75 years old with a high prostate specific antigen (between 2.5 and 10 ng/dl). Of these patients 98 (49%) had a diagnosis of type IV prostatitis. In a prospective, double-blind trial they were randomized to receive placebo (49 patients, group 1) or 500 mg ciprofloxacin (49 patients, group 2) twice a day for 4 weeks. Prostate specific antigen was determined after treatment and all patients underwent transrectal ultrasound guided biopsy of the prostate.



In group 1, 29 (59.18%) patients presented with a decrease in prostate specific antigen and 9 (31%) had cancer on biopsy, while in group 2 there were 26 (53.06%) patients with a decrease in prostate specific antigen and 7 (26.9%) with prostate cancer. There was no statistical difference in either group in relation to prostate specific antigen decrease after treatment or the presence of tumor.



A considerable number of patients (49%) were diagnosed with type IV prostatitis and high prostate specific antigen in agreement with the current literature. Of the patients 26.9% to 31% presented with a decrease in prostate specific antigen after the use of antibiotic or placebo and harbor cancer as demonstrated on prostate biopsy. Prostate specific antigen decreases do not indicate the absence of prostate cancer.
Progenitor content of autologous grafts: mobilized bone marrow vs mobilized blood

The progenitor content of autologous peripheral blood progenitor and stem cell collections is a major determinant of prompt hematopoietic recovery following autologous stem cell transplantation. We analyzed unstimulated bone marrow (BM) and peripheral blood (PB) apheresis products in comparison to those collected following G-CSF or GM-CSF stimulation. We quantitated their committed (CFU-GM) and primitive (long-term culture-initiating cells, LTC-IC) progenitors in relation to hematologic recovery in 63 patients undergoing autografting for lymphoid malignancies. G-CSF, but not GM-CSF, substantially enriched the committed progenitor content (2.5–3.6-fold) of both PB and BM grafts. G-CSF also enriched the LTC-IC content of BM and PB compared to control grafts. GM-CSF augmented (11.5-fold) the LTC-IC content of stimulated BM, but not GM-CSF-mobilized PB. Neutrophil recovery was substantially quicker in recipients of BM or PB mobilized with G-CSF or GM-CSF. In contrast, red cell and platelet recovery was accelerated in recipients of GM-CSF-stimulated BM (but not PB) and G-CSF-stimulated PB (but not BM). No direct correlation between progenitor dose and hematopoietic recovery for neutrophils, platelets or red cells was observed. Cytokine stimulation can augment the committed and more primitive multilineage progenitor content of BM and PB grafts, to a differing extent. The uncertain relationship with multilineage myeloid recovery emphasizes the limitations in using clonogenic progenitor analyses to assess the adequacy of an autologous graft prior to transplantation.
