Initial combination therapy versus step-up therapy in treatment to the target of remission in daily clinical practice in early rheumatoid arthritis patients: results from the DREAM registry.

Treat to target (T2T) is widely accepted as the standard of care for patients with rheumatoid arthritis (RA) and has been shown to be more effective than traditional routine care. The objective of this study was to compare the effectiveness of two T2T strategies in patients with early RA: a step-up approach starting with methotrexate (MTX) monotherapy (cohort I) versus an initial disease-modifying antirheumatic drug combination approach (cohort II).



A total of 128 patients from cohort II were case-control-matched with 128 patients from cohort I on gender, age, and baseline disease activity. Twelve-month follow-up data were available for 121 patients in both cohorts. The primary outcome was the proportion of patients having reached at least one 28-joint Disease Activity Score (DAS28) score <2.6 (remission) during 12 months of follow-up. Secondary outcomes were time until remission was achieved and mean DAS28 scores at 6- and 12-month follow-up.



After 12 months of follow-up, remission was reached at least once in 77.3 % of the patients in cohort II versus 71.9 % in cohort I (P = 0.31). Median time until first remission was 17 weeks in cohort II versus 27 weeks in cohort I (P = 0.04). A significant time by strategy interaction was found in mean DAS28 scores. Post hoc analysis revealed a significant difference in mean DAS28 scores between both cohorts at 6 months (P = 0.04), but not at 12 months (P = 0.36).



The initial combination strategy resulted in a comparable remission rate after 1 year but a significantly shorter time until remission. At 6 months, mean DAS28 scores were lower in patients with initial combination treatment than in those with step-up therapy. At 12 months, no significant differences remained in mean DAS28 scores or the proportion of patients in remission.
Effects of stocking rates on gastrointestinal nematode infection levels in a goat/cattle rotational stocking system.

Gastrointestinal nematodes (GIN) are increasingly resistant to anthelmintic drugs worldwide, so integrated control methods are more and more needed for the sustainability of small ruminant farming. Such methods rely on knowledge in epidemiology, physiology, and genetics. Ecological studies have highlighted the effect of host density on parasite populations, and in the humid tropics, rotational grazing systems were designed according to the survival of GIN free-living stages. This study aimed to assess the effects of mixed stocking and host stocking rate on host GIN infection level. Four groups of 15-17 Creole male kids were raised on irrigated pasture from weaning (about 3 months) until the age of 7 months, at four partial stocking rates (pSR): 100% (control), 75% (G75), 50% (G50), and 25% (G25) of the total stocking rate of the pasture. The last three groups were associated with weaned Creole heifers to obtain the same overall stocking rate as the control. Animals grazed in a 'leader' goat and 'follower' cattle design: the G25, G50, and G75 paddocks were split into six plots; each plot was grazed by goats for 1 week and by heifers the following week. The pasture then rested for 4 weeks before the animals were returned for a new grazing sequence. Five control plots were grazed rotationally for 1 week, and rested for 4 weeks. This design was repeated three times a year for a total of 10 repetitions. Average faecal egg counts (FEC) decreased according to a power function of the pSR: FEC=1829pSR(3.7). The observed death rate decreased significantly with the pSR (27.6%, 16.4%, 11.9%, and 12.2%). The kids grew faster in G25 (51 g d(-1)) than in G50 (43 g d(-1)) and G75 or control (32 g d(-1), p<0.05). Heifers were not significantly infected with GIN and grew normally (about 0.48 kg d(-1)). Reducing the pSR by associating a non-host species in a rotational stocking system may be a very promising component of integrated GIN control, at least for the humid tropics.
Challenges in motivating treatment enrollment in community syringe exchange participants

Participants of syringe exchange programs (SEPs) exhibit high rates of substance use disorder but remain extremely ambivalent about seeking treatment. This study evaluated the effectiveness of motivational interviewing (MI) for encouraging SEP participants to enroll in substance abuse treatment. New opioid-dependent registrants to the Baltimore Needle Exchange Program (BNEP) (n=302) completed the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV), and the Addiction Severity Index (ASI) and were randomly assigned to one of three treatment referral conditions: (1) MI, (2) job readiness (JR) (attention control), or (3) standard referral. Participants in each condition who expressed interest in treatment were referred to a treatment readiness group that provided further encouragement and referral to programs that were accepting new admissions. Participants were observed for 1 year following the intervention. The results showed that 10.9% of study participants enrolled in substance abuse treatment, although no condition effects were observed. White participants and those diagnosed with major depression were most likely to enter treatment. The results suggest that a single motivational interview is insufficient to motivate changes in treatment seeking in this population, whereas the identification of predictors of treatment enrollment is worthy of further investigation.
Outcomes of antiemetic prophylaxis in children undergoing bone marrow transplantation

A prospective survey of the control of acute and delayed antineoplastic and radiation-induced nausea and vomiting was undertaken in children undergoing bone marrow transplantation (BMT) at The Hospital for Sick Children. Prior administration of antineoplastic agents or irradiation, presence of anticipatory nausea or vomiting prior to starting the conditioning regimen, antiemetic use within 24 h of conditioning, the prescribed antineoplastic and/or radiation ablative regimen, and prescribed antiemetic regimens were recorded. Emetic episodes, dietary intake, administration of conditioning agents and antiemetics, and adverse effects were monitored on each day of the conditioning regimen and for 96 h thereafter. Children older than 3 years of age assessed their nausea on each study day. Twenty-five children were followed for 258 patient days. Children did not vomit or retch on 73% and 43% of patient days, in the acute and delayed phases, respectively. Nausea data were evaluable for 21 children on 200 patient days. Nausea was absent on 55% and 26% of patient days in the acute and delayed phases, respectively. Five children never had an emetic episode during the entire study period. One child was completely free from nausea and vomiting throughout the study period. Antineoplastic and radiation-induced nausea and vomiting can be successfully prevented in the majority of children undergoing BMT. However, effective treatment strategies must be developed in the event of antiemetic failure and for effective prophylaxis in children who cannot tolerate dexamethasone.
Metformin increases AMP-activated protein kinase activity in skeletal muscle of subjects with type 2 diabetes.

Metformin is an effective hypoglycemic drug that lowers blood glucose concentrations by decreasing hepatic glucose production and increasing glucose disposal in skeletal muscle; however, the molecular site of metformin action is not well understood. AMP-activated protein kinase (AMPK) activity increases in response to depletion of cellular energy stores, and this enzyme has been implicated in the stimulation of glucose uptake into skeletal muscle and the inhibition of liver gluconeogenesis. We recently reported that AMPK is activated by metformin in cultured rat hepatocytes, mediating the inhibitory effects of the drug on hepatic glucose production. In the present study, we evaluated whether therapeutic doses of metformin increase AMPK activity in vivo in subjects with type 2 diabetes. Metformin treatment for 10 weeks significantly increased AMPK alpha2 activity in the skeletal muscle, and this was associated with increased phosphorylation of AMPK on Thr172 and decreased acetyl-CoA carboxylase-2 activity. The increase in AMPK alpha2 activity was likely due to a change in muscle energy status because ATP and phosphocreatine concentrations were lower after metformin treatment. Metformin-induced increases in AMPK activity were associated with higher rates of glucose disposal and muscle glycogen concentrations. These findings suggest that the metabolic effects of metformin in subjects with type 2 diabetes may be mediated by the activation of AMPK alpha2.
Radiotherapy in implant-based immediate breast reconstruction: risk factors, surgical outcomes, and patient-reported outcome measures in a large Swedish multicenter cohort

The purpose of this large cohort study was to analyze the effects of prior and postoperative radiotherapy (RT) on surgical outcomes and patient-reported outcome measures (PROMs) in implant-based immediate breast reconstruction (IBR). All breast cancer patients (n = 725, of whom 29 had bilateral IBR) operated with implant-based IBR at four Stockholm hospitals from 2007 to 2011 were included. The median follow-up was 43 months. Three groups were compared: no RT (n = 386), prior RT (n = 64), and postoperative RT (n = 304). Outcomes were IBR failure (implant loss with or without secondary autologous reconstruction), unplanned reoperations, and PROMs, as measured by the BreastQ® questionnaire. IBR failure occurred in 22/386 (6 %) of non-irradiated cases, 16/64 (25 %) after prior and 45/304 (15 %) after postoperative RT (p < 0.001). Failure risk was higher after prior than postoperative RT (HR 9.28 vs. 3.08). Further risk factors were high BMI, less surgeon reconstructive experience, and postoperative infection, while the use of permanent implants lowered the risk of IBR failure. The estimated 5 years IBR failure rate was 10.4 % for non-irradiated, 28.2 % for previously and 25.2 % for postoperatively irradiated patients (p < 0.001). At least one unplanned reoperation occurred in 169/384 of non-irradiated (44 %), 42/64 (66 %) of previously, and 180/303 (59 %) of postoperatively irradiated breasts (p < 0.001). Further contributing factors were the use of one-stage expander and permanent implants, less surgeon reconstructive experience, and smoking. RT significantly impaired scores on all scales of the BreastQ®. However, a clear majority of women in all groups would choose IBR again. Implant-based IBR remains a feasible option for women undergoing mastectomy as patient satisfaction levels are high. After prior RT, however, autologous alternatives should be considered.
Application of the new GOLD COPD staging system to a US primary care cohort, with comparison to physician and patient impressions of severity

In 2011, the traditional Global Initiative for Chronic Obstructive Lung Disease (GOLD) COPD spirometry-based severity classification system was revised to also include exacerbation history and COPD Assessment Test (CAT) and modified Medical Research Council Dyspnea Scale (mMRC) scores. This study examined how COPD patients treated in primary care are reclassified by the new GOLD system compared to the traditional system, and each system's level of agreement with patient's or physician's severity assessments.



In this US multicenter cross-sectional study, COPD patients were recruited by 83 primary care practitioners (PCPs) to complete spirometry testing and a survey. Patients were classified by the traditional spirometry-based system (stages 1-4) and under the new system (grades A, B, C, D) using spirometry, exacerbation history, mMRC, and/or CAT results. Concordance between physician and patient-reported severity, spirometry stage, and ABCD grade based on either mMRC or CAT scores was examined.



Data from 445 patients with spirometry-confirmed COPD were used. As compared to the traditional system, the GOLD mMRC system reclassifies 47% of patients, and GOLD CAT system reclassifies 41%, but the distributions are very different. The GOLD mMRC system resulted in relatively equal distributions by ABCD grade (33%, 22%, 19%, 26%, respectively), but the GOLD CAT system put most into either B or D groups (9%, 45%, 4%, and 42%). The addition of exacerbation history reclassified only 19 additional patients. Agreement between PCPs' severity rating or their patients' self-assessment and the new ABCD grade was very poor (κ=0.17 or less).



As compared to the traditional system, the GOLD 2011 multidimensional system reclassified nearly half of patients, but how they were reclassified varied greatly by whether the mMRC or CAT questionnaire was chosen. Either way, the new system had little correlation with the PCPs or their patients' impressions about the COPD severity.
Evaluation of intramuscularly administered sodium pentosan polysulfate for treatment of experimentally induced osteoarthritis in horses.

To assess clinical, radiographic, histologic, and biochemical effects of sodium pentosan polysulfate (NaPPS) administered IM for treatment of experimentally induced osteoarthritis in horses.



18 horses.


PROCEDURES
Osteoarthritis was induced arthroscopically in 1 middle carpal joint of all horses. Nine horses received NaPPS (3 mg/kg, IM) on study days 15, 22, 29, and 36. Nine control horses received the same volume of saline (0.9% NaCl) solution IM on study days 15, 22, 29, and 36. Clinical, radiographic, gross, histologic, histochemical, and biochemical findings as well as findings of synovial fluid analysis were evaluated.



No adverse treatment-related events were detected. Induced osteoarthritis caused a substantial increase in lameness, response to flexion, joint effusion, radiographic findings, synovial membrane inflammation, and articular cartilage fibrillation. Articular cartilage fibrillation was substantially reduced by NaPPS treatment, and concentrations of chondroitin sulfate 846 epitope were significantly increased in the synovial fluid of osteoarthritic and non-osteoarthritic joints of treated horses.



Results indicated that NaPPS has some beneficial disease-modifying effects and may be a therapeutic option for osteoarthritis in horses.
Analysis of genetic and non-genetic factors that affect the QTc interval in a Mongolian population: the GENDISCAN study

The QTc interval is a complex quantitative trait and a strong prognostic indicator of cardiovascular mortality in general, healthy people. The aim of this study was to identify non-genetic factors and quantitative trait loci that govern the QTc interval in an isolated Mongolian population. We used multiple regression analysis to determine the relationship between the QTc interval and non-genetic factors including height, blood pressure, and the plasma lipid level. Whole genome linkage analyses were performed to reveal quantitative trait loci for the QTc interval with 349 microsatellite markers from 1,080 Mongolian subjects. Among many factors previously known for association with the QTc interval, age, sex, heart rate, QRS duration of electrocardiogram and systolic blood pressure were also found to have influence on the QTc interval. A genetic effect for the QTc interval was identified based on familial correlation with a heritability value of 0.31. In a whole genome linkage analysis, we identified the four potential linkage regions 7q31-34, 5q21, 4q28, and 2q36.
Efficacy of rivastigmine in comparison to ginkgo for treating Alzheimer's dementia.

To assess the efficacy of the Ginkgo biloba in patients with dementia of the Alzheimer type in slowing down the disease's degenerative progression and the patients' cognitive impairment compared with rivastigmine.



Total 56 patients aged 50-75 years, suffering from dementia, were allocated into one of the two treatments: group 1) Ginkgo biloba (120 mg daily dose); group 2) rivastigmine (4.5 mg daily dose) in a 24-week randomized double blind study. The degree of severity of dementia was assessed by the Seven Minute test and the Mini-Mental State Examination.



Our results confirm the clinical efficacy of rivastigmine in the dementia of the Alzheimer type, comparing to Ginkgo biloba. There are few published trials that have directly compared a cholinesterase inhibitor with Ginkgo for dementia. This study directly compares a cholinesterase inhibitor with Ginkgo biloba for dementia of the Alzheimer type.



Our study suggests that there are differences in the efficacy of Ginkgo biloba and rivastigmine in the treatment of Alzheimer's dementia. In addition, this study suggested that cholinesterase inhibitors should be used in preference to Ginkgo biloba in patients with mild to moderate AD.
Endoscopic placement of a tracheal oxygen catheter: a new technique

In patients with chronic obstructive pulmonary disease (COPD), intratracheal oxygen insufflation (ITO) is an established therapeutic approach. We developed a new endoscopic technique of intratracheal catheter placement. The aim of this pilot study was to demonstrate its short-term feasibility in acutely extubated patients with moderate to severe COPD who require oxygen therapy.  A guide wire was inserted through a nasally passed bronchoscope and was positioned such that its tip was placed intratracheally. Using a “Seldinger technique“, the tracheal catheter was then inserted over the wire to a point 2–3 cm proximal to the carina and positioned under direct vision from the bronchoscope inserted through the contralateral nose. After catheter insertion, the guide wire was removed. The patients scored catheter-associated local discomfort using a visual analogue scale. In a randomly assigned, crossover design, the effectiveness of the endoscopically (e) inserted ITO catheter was assessed by measuring the capillary blood gases, respiratory rate (RR), tidal volume (Vt) and minute ventilation (MV) after 1 h breathing room air without eITO and 1 h after eITO (flow: 3 l/min).  The eITO catheter was placed in all patients without complications and with only minimal discomfort in two patients (spontaneously reversible cough). Compared to breathing room air, capillary O2 pressure increased (from 54.7 ± 9.4 to 82.8 ± 21.8 mmHg) whereas Vt (from 458.7 ± 86.8 to 358.3 ± 75.1 ml) and MV (from 7.7 ± 1.5 to 5.5 ± 1.1 l/min) decreased significantly (each p < 0.0001) with eITO in all patients. The capillary CO2 pressure and RR did not change.  Acutely extubated patients in whom oxygen therapy is indicated may profit from eITO. This new technique works immediately and is thus an effective short-term intervention of potential value in the intensive care unit.
The effect of acupressure on quality of sleep in Iranian elderly nursing home residents.

Sleep disturbances are very common in elderly people and Traditional Chinese acupressure a noninvasive technique that promotes health and comfort recently has been used in this regard. The purpose of the present study was to evaluate the potential beneficial effects of acupressure on a group of institutionalized elders experiencing sleep disturbances.



A randomized controlled clinical trial was conducted to test the effectiveness of acupressure on quality of sleep of elderly residing in a Nursing home. The Pittsburgh Sleep Quality index (PSQI) questionnaire was used as a screening tool to select 90 residents with moderate to marked sleep disturbances. The elders were randomly assigned to an acupressure group, a sham acupressure group and a control group by Balanced randomization method.



There were significant differences between the acupressure group and the control group in subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency and sleep disturbance. But no significant differences were found in sleep indices between the sham acupressure group and the control group. Sleep log data showed a significant decrease in nocturnal awakenings in acupressure group compared to other two groups.



The findings of this study indicated that acupressure has an effect on improvement of sleep quality and endorsed it as a non-pharmacological and complementary therapy for sleep-disturbed elderly people.
Evaluation of myocardial ischemia after surgical repair of anomalous aortic origin of a coronary artery in a series of pediatric patients.

We sought to prospectively evaluate evidence of myocardial ischemia after surgical repair of anomalous aortic origin of a coronary artery with an interarterial course (AAOCA).



An AAOCA is a rare anomaly associated with increased myocardial ischemia and sudden death risk in children. Data evaluating ischemia after AAOCA repair are limited.



We included children who underwent AAOCA surgery between October 2001 and December 2006. They were prospectively assessed with exercise stress test (EST), stress echocardiogram (SE), and stress myocardial perfusion scan (MPS).



Of 24 participating children, 15 (63%) were male, 16 (67%) had anomalous right coronary (ARCA), and 7 (29%) were asymptomatic. Median age was 12 (5 to 18) years; follow-up was 15 (2 to 48) months. All had unobstructed neo-coronary ostia by echocardiogram and were asymptomatic. One anomalous origin of left main coronary artery (ALCA) patient and 8 ARCA patients had post-operative evaluations suggestive of ischemia. The ALCA patient had reversible apical septal and mid-anteroseptal hypokinesis on SE. Of the ARCA patients, 2 had inferior ST-segment depression on EST; subsequently, 1 had normal tests, but the other developed anterolateral Q waves. Two patients had blunted blood pressure response with EST, 1 had fixed apical inferior hypokinesis on SE, 2 had reversible perfusion defects on MPS, and 1 had a fixed perfusion defect on MPS.



Subclinical changes suggestive of ischemia might occur despite patent neo-coronary ostia, notably after ARCA repair. The implication of these results on indication for surgery and subsequent sudden death risk is unknown. Serial EST, SE, and MPS are essential in evaluating ongoing ischemia risk after AAOCA repair.
