    Housing First is a groundbreaking approach to ending chronic homelessness among people with mental illness. This article presents one-year findings from a multisite randomized controlled trial (RCT) comparing Housing First with treatment as usual. The study was a nonblind, parallel-group RCT conducted in five Canadian cities. A sample of 950 high-need participants with severe mental illness, who were either absolutely homeless or precariously housed, was randomly assigned to Housing First (N=469) or treatment as usual (N=481). Housing First participants received a rent supplement, assistance to find housing, and assertive community treatment. Treatment-as-usual participants had access to all other existing programs. At one-year follow-up, 73% of Housing First participants and 31% of treatment-as-usual participants resided in stable housing (plife was significantly greater among Housing First participants compared with treatment-as-usual participants (pHousing First participants also showed greater improvements in community functioning compared with treatment-as-usual participants (p=.003, d=.25, CI=.09-.41). Compared with treatment as usual, Housing First produced greater improvements in housing stability, quality of life, and community functioning after one year of enrollment. The study provides support for adopting Housing First as an approach for ending chronic homelessness among persons with severe mental illness, even if they are actively symptomatic or using substances.

    Full Text Available The objective of this study was to determine whether treatment with the nonselective nonsteroidal anti-inflammatory drug (NSAID indomethacin slows cognitive decline in patients with Alzheimer's disease (AD.This double-blind, randomized, placebo-controlled trial was conducted between May 2000 and September 2005 in two hospitals in the Netherlands. 51 patients with mild to moderate AD were enrolled into the study. Patients received 100 mg indomethacin or placebo daily for 12 months. Additionally, all patients received omeprazole. The primary outcome measure was the change from baseline after one year of treatment on the cognitive subscale of the AD Assessment Scale (ADAS-cog. Secondary outcome measures included the Mini-Mental State Examination, the Clinician's Interview Based Impression of Change with caregiver input, the noncognitive subscale of the ADAS, the Neuropsychiatric Inventory, and the Interview for Deterioration in Daily life in Dementia. Considerable recruitment problems of participants were encountered, leading to an underpowered study. In the placebo group, 19 out of 25 patients completed the study, and 19 out of 26 patients in the indomethacin group. The deterioration on the ADAS-cog was less in the indomethacin group (7.8+/-7.6, than in the placebo group (9.3+/-10.0. This difference (1.5 points; CI -4.5-7.5 was not statistically significant, and neither were any of the secondary outcome measures.The results of this study are inconclusive with respect to the hypothesis that indomethacin slows the progression of AD.

    Full Text Available Abstract Background Annual prevalence of gestational diabetes mellitus (GDM is 12.5% among Finnish pregnant women. The prevalence is expected to rise with the increasing overweight among women before pregnancy. Physical activity and diet are both known to have favourable effects on insulin resistance and possibly on the risk of GDM. We aimed to investigate, whether GDM can be prevented by counseling on diet, physical activity and gestational weight gain during pregnancy. Methods/Design A cluster-randomized controlled trial was conducted in 14 municipalities in the southern part of Finland. Pairwise randomization was performed in order to take into account socioeconomic differences. Recruited women were at 8-12 weeks' gestation and fulfilled at least one of the following criteria: body mass index ≥ 25 kg/m2, history of earlier gestational glucose intolerance or macrosomic newborn (> 4500 g, age ≥ 40 years, first or second degree relative with history of type 1 or 2 diabetes. Main exclusion criterion was pathological oral glucose tolerance test (OGTT at 8-12 weeks' gestation. The trial included one counseling session on physical activity at 8-12 weeks' gestation and one for diet at 16-18 weeks' gestation, and three to four booster sessions during other routine visits. In the control clinics women received usual care. Information on height, weight gain and other gestational factors was obtained from maternity cards. Physical activity, dietary intake and quality of life were followed by questionnaires during pregnancy and at 1-year postpartum. Blood samples for lipid status, hormones, insulin and OGTT were taken at 8-12 and 26-28 weeks' gestation and 1 year postpartum. Workability and return to work were elicited by a questionnaire at 1- year postpartum. Linkage to the national birth register of years 2007-2009 will provide information on perinatal complications and GDM incidence among the non-participants of the study. Cost

    Perpetration of physical, sexual, and psychological abuse is prevalent in adolescent relationships. One strategy for reducing such violence is to increase the likelihood that youth will intervene when they see peers engaging in disrespectful and abusive behaviors. This 12-month follow-up of a cluster RCT examined the longer-term effectiveness of Coaching Boys Into Men, a dating violence prevention program targeting high school male athletes. This cluster RCT was conducted from 2009 to 2011. The unit of randomization was the school, and the unit of analysis was the athlete. Data were analyzed in 2012. Participants were male athletes in Grades 9-11 (N=1513) participating in athletics in 16 high schools. The intervention consisted of training athletic coaches to integrate violence prevention messages into coaching activities through brief, weekly, scripted discussions with athletes. Primary outcomes were intentions to intervene, recognition of abusive behaviors, and gender-equitable attitudes. Secondary outcomes included bystander behaviors and abuse perpetration. Intervention effects were expressed as adjusted mean between-arm differences in changes in outcomes over time, estimated via regression models for clustered, longitudinal data. Perpetration of dating violence in the past 3 months was less prevalent among intervention athletes relative to control athletes, resulting in an estimated intervention effect of -0.15 (95% CI=-0.27, -0.03). Intervention athletes also reported lower levels of negative bystander behaviors (i.e., laughing and going along with peers' abusive behaviors) compared to controls (-0.41, 95% CI=-0.72, -0.10). No differences were observed in intentions to intervene (0.04, 95% CI=-0.07, 0.16); gender-equitable attitudes (-0.04, 95% CI=-0.11, 0.04); recognition of abusive behaviors (-0.03, 95% CI=-0.15, 0.09); or positive bystander behaviors (0.04, 95% CI=-0.11, 0.19).

    Computer-tailored programs may help to prevent overweight and obesity, which are worldwide public health problems. This study investigated (1) the 12-month effectiveness of a video- and text-based computer-tailored intervention on energy intake, physical activity, and body mass index (BMI), and (2) the role of educational level in intervention effects. A randomized controlled trial in The Netherlands was conducted, in which adults were allocated to a video-based condition, text-based condition, or control condition, with baseline, 6 months, and 12 months follow-up. Outcome variables were self-reported BMI, physical activity, and energy intake. Mixed-effects modelling was used to investigate intervention effects and potential interaction effects. Compared to the control group, the video intervention group was effective regarding energy intake after 6 months (least squares means (LSM) difference = −205.40, p = 0.00) and 12 months (LSM difference = −128.14, p = 0.03). Only video intervention resulted in lower average daily energy intake after one year (d = 0.12). Educational role and BMI did not seem to interact with this effect. No intervention effects on BMI and physical activity were found. The video computer-tailored intervention was effective on energy intake after one year. This effect was not dependent on educational levels or BMI categories, suggesting that video tailoring can be effective for a broad range of risk groups and may be preferred over text tailoring.

    Full Text Available The objective of the present study was to evaluate the effectiveness of a one-year multi-component immersive day-camp weight-loss intervention for children with overweight and obesity. The study design was a parallel-group randomized controlled trial. One hundred fifteen 11-13-year-old children with overweight and obesity were randomized into either: A six-week day-camp intervention arm focusing on increased physical activity, and healthy diet followed by a subsequent one-year family-based intervention, or a standard intervention arm consisting of one weekly exercise session for six weeks. Body mass index (BMI was the primary outcome. BMI z-score, clustered cardiovascular risk z-score, and body composition were secondary outcomes. All outcomes were measured at baseline, six week-, and 52 week follow-up. After six weeks, children from the day-camp intervention arm had improved their BMI (-2.2 kg/m2 (95% CI -2.6 to -1.7, P<0.001 and all secondary outcomes when compared to the children from the standard intervention arm. After 52 weeks, the day-camp intervention arm had a lower BMI (-1.2 kg/m2 (95% CI -1.8 to -0.5, P = 0.001, and BMI z-score (-0.20 (95% CI -0.35 to -0.05, P = 0.008, and clustered cardiovascular risk z-score (-0.23 (95% CI -0.37 to -0.08, P = 0.002 compared to the standard intervention arm. No group differences were detected in body composition after 52 weeks. This study shows that the day-camp intervention arm is effective in reducing BMI and improving the metabolic health of children with overweight and obesity. However, the effects seem to be diminishing over time.

    Objective To compare the long term effects of yoga based cardiac rehabilitation program with only physiotherapy based program as an add-on to conventional rehabilitation after coronary artery bypass grafting (CABG) on risk factors. Methods In this single blind prospective randomized parallel two armed active control study, 1026 patients posted for CABG at Narayana Hrudayalaya Institute of Cardiac Sciences, Bengaluru (India) were screened. Of these, 250 male participants (35–65 years) who satisfied the selection criteria and consented were randomized into two groups. Within and between group comparisons were done at three points of follow up (i.e. 6th week, 6th month, and 12th month) by using Wilcoxon's signed ranks test and Mann Whitney U test respectively. Results Yoga group had significantly (p = 0.001, Mann Whitney) better improvement in LVEF than control group in those with abnormal baseline EF (yoga group (p = 0.038, between groups) in those with high baseline BMI (≥23) after 12 months. Yoga group showed significant (p = 0.008, Wilcoxon's) reduction in blood glucose at one year in those with high baseline FBS ≥110 mg/dl. There was significantly better improvement in yoga than the control group in HDL (p = 0.003), LDL (p = 0.01) and VLDL (p = 0.03) in those with abnormal baseline values. There was significantly better improvement (p = 0.02, between groups) in positive affect in yoga group. Within Yoga group, there was significant decrease in perceived stress (p = 0.001), anxiety (p = 0.001), depression (p = 0.001), and negative affect (p = 0.03) while in the control group there was reduction (p = 0.003) only in scores on anxiety. Conclusion Addition of yoga based relaxation to conventional post-CABG cardiac rehabilitation helps in better management of risk factors in those with abnormal baseline values and may help in preventing recurrence.

    Full Text Available Background. Weight lost by obese patients is almost always regained over time. Extended treatment may improve maintenance, but solid evidence is lacking. Purpose. We determined effectiveness of maintenance therapy after a weight loss program. Methods. Together 201 patients (mean age 47 years and BMI 42 kg/m2, 71% women were randomly assigned to either a 17-week weight loss program followed by a one-year maintenance program or to a weight loss program without subsequent maintenance intervention. The weight loss program included behavior modification and a very-low-calorie diet, and maintenance program behavior modification. The primary outcome measure was percentage of patients with 5% or more weight loss at the end of maintenance (week 69 and one year later (week 121. Secondary outcomes were weight related changes in lifestyle and quality of life. Results. At week 69, 52% of the patients with and 44% of those without maintenance program had lost weight ≥5%, P=0.40, and, at week 121, 33% and 34%, P=0.77, respectively. At week 121 secondary outcomes did not differ between the groups among those successfully followed up. Conclusions. This one-year maintenance program was not effective in preventing weight regain in severely obese patients. Trial Registration. This trial is registered under clinicaltrials.gov Identifier: NCT00590655.

    Procrastination is a common self-regulatory failure that can have a negative impact on well-being and performance. However, few clinical trials have been conducted, and no follow-up has ever been performed. The current study therefore aimed to provide evidence for the long-term benefits and investigate predictors of a positive treatment outcome among patients receiving Internet-based cognitive behavior therapy (ICBT). A total of 150 self-recruited participants were randomized to guided or unguided ICBT. Self-report measures of procrastination, depression, anxiety, and quality of life were distributed at pre-treatment assessment, post-treatment assessment, and one-year follow-up. Mixed effects models were used to investigate the long-term gains, and multiple linear regression for predictors of a positive treatment outcome, using the change score on the Irrational Procrastination Scale as the dependent variable. Intention-to-treat was implemented for all statistical analyses. Large within-group effect sizes for guided and unguided ICBT, Cohen's d = .97-1.64, were found for self-report measures of procrastination, together with d = .56-.66 for depression and anxiety. Gains were maintained, and, in some cases, improved at follow-up. Guided and unguided ICBT did not differ from each other, mean differences -.31-1.17, 95% CIs [-2.59-3.22], and none of the predictors were associated with a better result, bs -1.45-1.61, 95% CIs [-3.14-4.26]. In sum, ICBT could be useful and beneficial in relation to managing procrastination, yielding great benefits up to one year after the treatment period has ended, with comparable results between guided and unguided ICBT.

    A randomized controlled trial conducted in patients with gastroesophageal reflux disease compared optimized medical therapy using proton pump inhibitor (n = 52) with laparoscopic Nissen fundoplication (n = 52). Patients were monitored for 1 year. The primary end point was frequency of gastroesophageal reflux dis-ease symptoms. Surgical patients had improved symptoms, pH control, and overall quality of life health index after surgery at 1 year compared with the medical group. The overall gastroesophageal reflux disease symptom score at 1 year was unchanged in the medical patients, but improved in the surgical patients. Fourteen patients in the medical arm experienced symptom relapse requiring titration of the proton pump inhibitor dose, but 6 had satisfactory symptom remission. No surgical patients required additional treatment for symptom control. Patients controlled on long-term proton pump inhibitor therapy for chronic gastroesophageal reflux disease are excellent surgical candidates and should experience improved symptom control after surgery at 1 year.

    To investigate the effectiveness of a quality improvement educational program in rural hospitals. Hospital-randomized controlled trial. A total of 47 rural and small community hospitals in Texas that had previously received a web-based benchmarking and case-review tool. The 47 hospitals were randomized either to receive formal quality improvement educational program or to a control group. The educational program consisted of two 2-day didactic sessions on continuous quality improvement techniques, followed by the design, implementation and reporting of a local quality improvement project, with monthly coaching conference calls and annual follow-up conclaves. Performance on core measures for community-acquired pneumonia and congestive heart failure were compared between study groups to evaluate the impact of the educational program. No significant differences were observed between the study groups on any measures. Of the 23 hospitals in the intervention group, only 16 completed the didactic program and 6 the full training program. Similar results were obtained when these groups were compared with the control group. While the observed results suggest no incremental benefit of the quality improvement educational program following implementation of a web-based benchmarking and case-review tool in rural hospitals, given the small number of hospitals that completed the program, it is not conclusive that such programs are ineffective. Further research incorporating supporting infrastructure, such as physician champions, financial incentives and greater involvement of senior leadership, is needed to assess the value of quality improvement educational programs in rural hospitals.

    The German Research Activities on Natural Urologicals (GRANU) study was a randomized, partially blinded, placebo-controlled, parallel-group trial that investigated the efficacy of pumpkin seed in men with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH/LUTS). A total of 1,431 men (50-80 years) with BPH/LUTS were randomly assigned to either pumpkin seed (5 g b.i.d.), capsules with pumpkin seed extract (500 mg b.i.d.) or matching placebo. The primary response criterion was a decrease in International Prostate Symptom Score (IPSS) of ≥5 points from baseline after 12 months. Secondary outcome measures included IPSS-related quality of life, IPSS single items and diary-recorded nocturia. After 12 months, the response rate (intention-to-treat/last-observation-carried-forward approach) did not differ between pumpkin seed extract and placebo. In the case of pumpkin seed (responders: 58.5%), the difference compared with placebo (responders: 47.3%) was descriptively significant. The study products were well tolerated. Overall, in men with BPH, 12 months of treatment with pumpkin seed led to a clinically relevant reduction in IPSS compared with placebo. In order to fully justify a recommendation for the use of pumpkin seed to treat moderate LUTS, these findings need to be substantiated in a confirmatory study or systematic review. 2014 S.

    The objective of this prospective parallel randomized single-blind study was to assess that a cycle of mud-bath therapy (MBT) provides any benefits over usual treatment in patients with bilateral knee osteoarthritis (OA). Patients with symptomatic primary bilateral knee OA, according to ACR criteria, were included in the study and randomized to one of two groups: one group received a cycle of MBT at spa center of Chianciano Terme (Italy) in addition to the usual treatment, and one group continued their regular care routine alone. Clinical assessments were performed 7 days before enrollment (screening visit), at the time of enrollment (basal time), after 2 weeks, and after 3, 6, 9, and 12 months after the beginning of the study. All assessments were conducted by two researchers blinded to treatment allocation. The primary efficacy outcomes were the global pain score evaluated by Visual Analog Scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) subscore for physical function (W-TPFS). Of the 235 patients screened, 103 met the inclusion criteria: 53 patients were included in the MBT group and 50 in the control group. In the group of patients treated with MBT, we observed a statistically significant ( p knee OA that lasts over time. Mud-bath therapy can represent a useful backup to pharmacologic treatment of knee OA or a valid alternative for patients who do not tolerate pharmacological treatments.

    Full Text Available Abstract Background Although task-oriented training has been shown to improve walking outcomes after stroke, it is not yet clear whether one task-oriented approach is superior to another. The purpose of this study is to compare the effectiveness of the Motor Learning Walking Program (MLWP, a varied overground walking task program consistent with key motor learning principles, to body-weight-supported treadmill training (BWSTT in community-dwelling, ambulatory, adults within 1 year of stroke. Methods/Design A parallel, randomized controlled trial with stratification by baseline gait speed will be conducted. Allocation will be controlled by a central randomization service and participants will be allocated to the two active intervention groups (1:1 using a permuted block randomization process. Seventy participants will be assigned to one of two 15-session training programs. In MLWP, one physiotherapist will supervise practice of various overground walking tasks. Instructions, feedback, and guidance will be provided in a manner that facilitates self-evaluation and problem solving. In BWSTT, training will emphasize repetition of the normal gait cycle while supported over a treadmill, assisted by up to three physiotherapists. Outcomes will be assessed by a blinded assessor at baseline, post-intervention and at 2-month follow-up. The primary outcome will be post-intervention comfortable gait speed. Secondary outcomes include fast gait speed, walking endurance, balance self-efficacy, participation in community mobility, health-related quality of life, and goal attainment.

    Although task-oriented training has been shown to improve walking outcomes after stroke, it is not yet clear whether one task-oriented approach is superior to another. The purpose of this study is to compare the effectiveness of the Motor Learning Walking Program (MLWP), a varied overground walking task program consistent with key motor learning principles, to body-weight-supported treadmill training (BWSTT) in community-dwelling, ambulatory, adults within 1 year of stroke. A parallel, randomized controlled trial with stratification by baseline gait speed will be conducted. Allocation will be controlled by a central randomization service and participants will be allocated to the two active intervention groups (1:1) using a permuted block randomization process. Seventy participants will be assigned to one of two 15-session training programs. In MLWP, one physiotherapist will supervise practice of various overground walking tasks.

    Recent research identifies unhealthful weight-control behaviors (fasting, vomiting, or laxative abuse) induced by a negative experience of the body, as the common antecedents of both obesity and eating disorders. In particular, according to the allocentric lock hypothesis, individuals with obesity may be locked to an allocentric (observer view) negative memory of the body that is no longer updated by contrasting egocentric representations driven by perception. In other words, these patients may be locked to an allocentric negative representation of their body that their sensory inputs are no longer able to update even after a demanding diet and a significant weight loss. To test the brief and long-term clinical efficacy of an enhanced cognitive-behavioral therapy including a virtual reality protocol aimed at unlocking the negative memory of the body (ECT) in morbidly obese patients with binge eating disorders (BED) compared with standard cognitive behavior therapy (CBT) and an inpatient multimodal treatment (IP) on weight loss, weight loss maintenance, BED remission, and body satisfaction improvement, including psychonutritional groups, a low-calorie diet (1200 kcal/day), and physical training. 90 obese (BMI>40) female patients with BED upon referral to an obesity rehabilitation center were randomly assigned to conditions (31 to ECT, 30 to CBT, and 29 to IP). Before treatment completion, 24 patients discharged themselves from hospital (4 in ECT, 10 in CBT, and 10 in IP). The remaining 66 inpatients received either 15 sessions of ECT, 15 sessions of CBT, or no additional treatment over a 5-week usual care inpatient regimen (IP). ECT and CBT treatments were administered by 3 licensed psychotherapists, and patients were blinded to conditions. At start, upon completion of the inpatient treatment, and at 1-year follow-up, patients' weight, number of binge eating episodes during the previous month, and body satisfaction were assessed by self-report questionnaires and

    Full Text Available Recently, we conducted a prospective randomized controlled trial (RCT showing that a 6-month 130g/day low-carbohydrate diet (LCD reduced HbA1c and BMI more than a calorie restricted diet (CRD. [1] To assess whether the benefits of the LCD persisted after the intensive intervention, we compared HbA1c and BMI between the LCD and CRD groups at 1 year after the end of the 6-month RCT.Following the end of the 6-month RCT, patients were allowed to manage their own diets with periodic outpatient visits. One year later, we analyzed clinical and nutrition data.Of the 66 participants in the original study, 27 in the CRD group and 22 in the LCD group completed this trial. One year after the end of the original RCT, the carbohydrate intake was comparable between the groups (215 [189-243]/day in the CRD group and 214 (176-262 g/day in the LCD group. Compared with the baseline data, HbA1c and BMI were decreased in both groups (CRD: HbA1c -0.4 [-0.9 to 0.3] % and BMI -0.63 [-1.20 to 0.18] kg/m2; LCD: HbA1c -0.35 [-1.0 to 0.35] % and BMI -0.77 [-1.15 to -0.12] kg/m2. There were no significant differences in HbA1c and BMI between the groups.One year after the diet therapy intervention, the beneficial effect of the LCD on reduction of HbA1c and BMI did not persist in comparison with CRD. However, combining the data of both groups, significant improvements in HbA1c and BMI from baseline were observed. Although the superiority of the LCD disappeared 1 year after the intensive intervention, these data suggest that well-constructed nutrition therapy programs, both CRD and LCD, were equally effective in improving HbA1c for at least 1 year.University Hospital Medical Information Network (UMIN ID000010663.

Specialized rehabilitation centre. A total of 170 patients (mean age of 53 years (13); 121 females). The multidisciplinary group underwent a multidisciplinary rehabilitation programme combining multimodal exercises with psychologist-lead cognitive-behavioural therapy sessions. The general exercise group underwent general physiotherapy. Both groups followed group-based programmes once a week for ten weeks. Additionally, the multidisciplinary group met with the psychologist once a week for a 60-minute session. The Neck Disability Index (primary outcome), the Tampa Scale for Kinesiophobia, the Pain Catastrophizing Scale, a pain numerical rating scale and the Short-Form Health Survey. The participants were evaluated before, after training and after 12 months. A linear mixed model for repeated measures was used for each outcome measure. Significant effects ( p-value rehabilitation programme including cognitive-behavioural therapy was superior to group-based general physiotherapy in improving disability, pain and quality of life of subjects with chronic neck pain. The effects lasted for at least one year.

    Burn patients are at risk of hypovitaminosis D and osteopenia or sarcopenia. Vitamin D pleiotropic effects may influence bone and muscle health. The aim of this pilot study was to assess effects of a cholecalciferol (VD3) supplementation and an optimized calcium (Ca) regimen on vitamin D (VD) status, bone and muscle health during sequelar stage of burn injury. Monocentric randomized controlled trial. Fifteen adults with thermal burns dating from 2 to 5 years were randomized into two groups. For 12 months, they either received a quarterly IM injection of 200,000IU VD3 and daily oral Ca (Group D) or placebo (Group P). VD status and bone remodeling markers were assessed every 3 months. Knee muscle strength and bone mineral density were, respectively, assessed using isokinetic dynamometry and dual X-ray absorptiometry at initiation (M0) and completion (M12) of the protocol. Of all the patients, 66% presented with VD deficiency and 53% (with 3 men burn adults. When combined with optimized Ca intakes, it demonstrated positive effects on muscle health but not on bone health. A high prevalence of hypovitaminosis D and osteopenia in these patients, as well as their wide range of muscle performances, seem to be worrying when considering rehabilitation and quality of life.

    Full Text Available The RTS,S/AS02(D vaccine has been shown to have a promising safety profile, to be immunogenic and to confer protection against malaria in children and infants.We did a randomized, controlled, phase I/IIb trial of RTS,S/AS02(D given at 10, 14 and 18 weeks of age staggered with routine immunization vaccines in 214 Mozambican infants. The study was double-blind until the young child completed 6 months of follow-up over which period vaccine efficacy against new Plasmodium falciparum infections was estimated at 65.9% (95% CI 42.6-79.8, p<0.0001. We now report safety, immunogenicity and estimated efficacy against clinical malaria up to 14 months after study start. Vaccine efficacy was assessed using Cox regression models. The frequency of serious adverse events was 32.7% in the RTS,S/AS02(D and 31.8% in the control group. The geometric mean titers of anti-circumsporozoite antibodies declined from 199.9 to 7.3 EU/mL from one to 12 months post dose three of RTS,S/AS02(D, remaining 15-fold higher than in the control group. Vaccine efficacy against clinical malaria was 33% (95% CI: -4.3-56.9, p = 0.076 over 14 months of follow-up. The hazard rate of disease per 2-fold increase in anti-CS titters was reduced by 84% (95% CI 35.1-88.2, p = 0.003.The RTS,S/AS02(D malaria vaccine administered to young infants has a good safety profile and remains efficacious over 14 months. A strong association between anti-CS antibodies and risk of clinical malaria has been described for the first time. The results also suggest a decrease of both anti-CS antibodies and vaccine efficacy over time.ClinicalTrials.gov NCT00197028.

    This study aimed to investigate the mediating pathway of 3 factors (psychotic symptoms, attitude toward medication, and cognitive processing speed) on the effect of insight on personal-social functioning in patients with schizophrenia. Chinese inpatients with schizophrenia (n = 168; mean age 18 ± 50 years) diagnosed according to the DSM-IV were randomly assigned to treatment with antipsychotic medication alone or combined treatment. Positive and Negative Syndrome Scale (PANSS), Drug Attitude Inventory (DAI), Assessment of Insight (SAI), and Social-Personal Performance Scale (PSPS) scores were evaluated at baseline and at 3, 6, and 12 months. Cognitive function was assessed at baseline. Multiple mediation analyses were conducted with baseline data, end point data, and changes-in-scale scores between baseline and the end point, respectively. At baseline and at 12 months, only psychotic symptoms mediated the effect of insight on personal-social functioning. For changes-in-scale scores over the 12-month follow-up, in patients receiving treatment with medication alone, the effect of improved insight on improved personal-social function was mediated by psychotic symptoms only; in patients receiving a combined treatment, the effect of improved insight on improved personal-social functioning was mediated by both psychotic symptoms and attitudes toward medication, independently. The link between insight and personal-social functions is mainly mediated by psychotic symptoms. Psychosocial intervention improves the predicting effect of insight on personal-social function by improving both the attitude toward medication and psychotic symptoms independently. © 2018 S.

    Full Text Available Abstract Background Cancer diseases and their therapies have negative effects on the quality of life. The aim of this study is to assess the effectiveness of case management in a sample of oncological outpatients with the intent of rehabilitation after cancer treatment. Case management wants to support the complex information needs of the patients in addition to the segmented structure of the health care system. Emphasis is put on support for self-management in order to enhance health - conscious behaviour, learning to deal with the burden of the illness and providing the opportunity for regular contacts with care providers. We present a study protocol to investigate the efficacy of a case management in patients following oncology rehabilitation after cancer treatment. Methods The trial is a multicentre, two-arm randomised controlled study. Patients are randomised parallel in either 'usual care' plus case management or 'usual care' alone. Patients with all types of cancer can be included in the study, if they have completed the therapy with chemo- and/or radiotherapy/surgery with curative intention and are expected to have a survival time >1 year. To determine the health-related quality of life the general questionnaire FACT G is used. The direct correlation between self-management and perceived self-efficacy is measured with the Jerusalem & Schwarzer questionnaire. Patients satisfaction with the care received is measured using the Patient Assessment of Chronic Illness Care 5 As (PACIC-5A. Data are collected at the beginning of the trial and after 3, 6 and 12 months. The power analysis revealed a sample size of 102 patients. The recruitment of the centres began in 2009. The inclusion of patients began in May 2010. Discussion Case management has proved to be effective regarding quality of life of patients with chronic diseases. When it comes to oncology, case management is mainly used in cancer treatment, but it is not yet common in the

    The effectiveness of nurse-led motivational interviewing (MI) in routine diabetes care in general practice is inconclusive. Knowledge about the extent to which nurses apply MI skills and the factors that affect the usage can help to understand the black box of this intervention. The current study compared MI skills of trained versus non-trained general practice nurses in diabetes consultations. The nurses participated in a cluster randomized trial in which a comprehensive program (including MI training) was tested on improving clinical parameters, lifestyle, patients' readiness to change lifestyle, and quality of life. Fifty-eight general practices were randomly assigned to usual care (35 nurses) or the intervention (30 nurses). The ratings of applying 24 MI skills (primary outcome) were based on five consultation recordings per nurse at baseline and 14 months later. Two judges evaluated independently the MI skills and the consultation characteristics time, amount of nurse communication, amount of lifestyle discussion and patients' readiness to change. The effect of the training on the MI skills was analysed with a multilevel linear regression by comparing baseline and the one-year follow-up between the interventions with usual care group. The overall effect of the consultation characteristics on the MI skills was studied in a multilevel regression analyses. At one year follow up, it was demonstrated that the nurses improved on 2 of the 24 MI skills, namely, "inviting the patient to talk about behaviour change" (mean difference=0.39, p=0.009), and "assessing patient's confidence in changing their lifestyle" (mean difference=0.28, p=0.037). Consultation time and the amount of lifestyle discussion as well as the patients' readiness to change health behaviour was associated positively with applying MI skills. The maintenance of the MI skills one year after the training program was minimal. The question is whether the success of MI to change unhealthy behaviour must be

    Full Text Available Existing models for predicting mortality based on traditional Cox proportional hazard approach (CPH often have low prediction accuracy. This paper aims to develop a clinical risk model with good accuracy for predicting 1-year mortality in cardiac arrhythmias patients using random survival forest (RSF, a robust approach for survival analysis. 10,488 cardiac arrhythmias patients available in the public MIMIC II clinical database were investigated, with 3,452 deaths occurring within 1-year followups. Forty risk factors including demographics and clinical and laboratory information and antiarrhythmic agents were analyzed as potential predictors of all-cause mortality. RSF was adopted to build a comprehensive survival model and a simplified risk model composed of 14 top risk factors. The built comprehensive model achieved a prediction accuracy of 0.81 measured by c-statistic with 10-fold cross validation. The simplified risk model also achieved a good accuracy of 0.799. Both results outperformed traditional CPH (which achieved a c-statistic of 0.733 for the comprehensive model and 0.718 for the simplified model. Moreover, various factors are observed to have nonlinear impact on cardiac arrhythmias prognosis. As a result, RSF based model which took nonlinearity into account significantly outperformed traditional Cox proportional hazard model and has great potential to be a more effective approach for survival analysis.

    This prospective, randomized, split-mouth clinical trial evaluated the clinical performance of conventional glass ionomer cement (GIC; Riva Self-Cure, SDI), supplied in capsules or in powder/liquid kits and placed in Class I cavities in permanent molars by the Atraumatic Restorative Treatment (ART) approach. A total of 80 restorations were randomly placed in 40 patients aged 11-15 years. Each patient received one restoration with each type of GIC. The restorations were evaluated after periods of 15 days (baseline), 6 months, and 1 year, according to ART criteria. Wilcoxon matched pairs, multivariate logistic regression, and Gehan-Wilcoxon tests were used for statistical analysis. Patients were evaluated after 15 days (n=40), 6 months (n=34), and 1 year (n=29). Encapsulated GICs showed significantly superior clinical performance compared with hand-mixed GICs at baseline (p=0.017), 6 months (p=0.001), and 1 year (p=0.026). For hand-mixed GIC, a statistically significant difference was only observed over the period of baseline to 1 year (p=0.001). Encapsulated GIC presented statistically significant differences for the following periods: 6 months to 1 year (p=0.028) and baseline to 1 year (p=0.002). Encapsulated GIC presented superior cumulative survival rate than hand-mixed GIC over one year. Importantly, both GICs exhibited decreased survival over time. Encapsulated GIC promoted better ART performance, with an annual failure rate of 24%; in contrast, hand-mixed GIC demonstrated a failure rate of 42%.

    The aim of this prospective randomized multicenter study was to compare retropubic tension-free vaginal tape (TVT) with TVT Secur in terms of efficacy and safety. We set out to enrol 280 stress urinary incontinent (SUI) women with a half-time interim analysis of short-term cure and adverse events. The short-term results have previously been published. Of the 133 randomized women, 125 underwent surgery, and 121 (TVT n = 61, TVT Secur n = 60) were available for follow-up 1 year postsurgery. No significant differences were found between groups regarding demographics or incontinence grade. One year after surgery, both subjective and objective cure rates were significantly lower for TVT Secur than for TVT (subjective cure: TVT 98 %, TVT Secur 80 %, p = 0.03; objective cure: TVT 94 %, TVT Secur 71 % for cough test, p = 0.01; TVT 76 %, TVT Secur 58 % for pad test, p = 0.05 ). Three major complications occurred in the TVT Secur group: one tape erosion into the urethra, one tape inadvertently placed into the bladder, and one immediate postoperative bleeding due to injury to the corona mortis. No major complications occurred in the TVT group. No significant differences were found between groups regarding peroperative bleeding, hospital stay, urge symptoms, residual urinary volume, subjective bladder emptying problems, postoperative urinary tract infections, and minor complications. The TVT Secur group used more antimuscarine medication after surgery than the TVT group (p = 0.03). Median time for surgery was 13 and 22 min for TVT Secur and TVT, respectively (p TVT Secur procedure had significantly inferior subjective and objective cure rates compared with the retropubic TVT procedure. Three serious adverse events occurred in the TVT Secur group. We therefore discourage further use of TVT Secur.

    To assess the effectiveness of a smoking cessation intervention at the workplace. The intervention was adapted to smokers' tobacco dependence, and included minimal structured counselling at the first visit (5-8 minutes), nicotine patches for three months, and three sessions of counselling for reinforcement of abstinence (2-3 minutes) over a three month period. Open randomised trial with two groups: the intervention group, and the control group which was subjected to standard clinical practice, consisting of short (30 seconds to one minute) sporadic sessions of unstructured medical antismoking advice. The trial was carried out among 217 smokers of both sexes, aged 20-63 years, motivated to quit smoking and without contraindications for nicotine patches, who were employees at a public transport company and at two worksites of an electric company. The main outcome measure was self reported tobacco abstinence confirmed by carbon monoxide in expired air workplace is effective to achieve long term smoking cessation. In a setting similar to ours, nine subjects would have to be treated for three months for one to achieve continuous abstinence for 12 months.

    The relationship between glycemic control and adverse outcomes found in a population with diabetes has seldom been evaluated in patients with type 2 diabetes. We explored the association between hemoglobin A1c (HbA1c) and hospitalization risks within one-year and eight-year follow-up periods. We conducted a retrospective cohort study on 57,061 patients with type 2 diabetes from National Diabetes Case Management Program during 2002-2004 in Taiwan. HbA1c at baseline and in-hospital mortality, all-cause and cause-specific hospitalization over one year and eight years were analyzed. After multivariate adjustment, one-year risk was higher for cases with HbA1c level risk of hypoglycemia hospitalization (0.81, 95% CI: 0.74-0.88). For eight-year risk, subjects with HbA1c level risks of all-cause and diabetes-related hospitalization (1.04, 1.03-1.05, and 1.15, 1.14-1.17, respectively). Higher HbA1c level correlated with lower one-year risk due to hypoglycemia hospitalization but increased one-year and eight-year risks due to all-cause and diabetes-specific hospitalization among Chinese people with type 2 diabetes in Taiwan. Future study must ascertain how to meet HbA1c targets and improve outcome without risk to this population. Copyright © 2015 Elsevier Inc. All rights reserved.

    The PREvención con DIeta MEDiterránea (PREDIMED) trial showed that Mediterranean diets (MedDiets) supplemented with either extravirgin olive oil or nuts reduced cardiovascular events, particularly stroke, compared with a control, lower fat diet. The mechanisms of cardiovascular protection remain unclear. We evaluated the 1-year effects of supplemented MedDiets on 24-hour ambulatory blood pressure (BP), blood glucose, and lipids. Randomized, parallel-design, controlled trial was conducted in 2 PREDIMED sites. Diets were ad libitum, and no advice on increasing physical activity or reducing sodium intake was given. Participants were 235 subjects (56.5% women; mean age, 66.5 years) at high cardiovascular risk (85.4% with hypertension). Adjusted changes from baseline in mean systolic BP were -2.3 (95% confidence interval [CI], -4.0 to -0.5) mm Hg and -2.6 (95% CI, -4.3 to -0.9) mm Hg in the MedDiets with olive oil and the MedDiets with nuts, respectively, and 1.7 (95% CI, -0.1 to 3.5) mm Hg in the control group (P<0.001). Respective changes in mean diastolic BP were -1.2 (95% CI, -2.2 to -0.2), -1.2 (95% CI, -2.2 to -0.2), and 0.7 (95% CI, -0.4 to 1.7) mm Hg (P=0.017). Daytime and nighttime BP followed similar patterns. Mean changes from baseline in fasting blood glucose were -6.1, -4.6, and 3.5 mg/dL (P=0.016) in the MedDiets with olive oil, MedDiets with nuts, and control diet, respectively; those of total cholesterol were -11.3, -13.6, and -4.4 mg/dL (P=0.043), respectively. In high-risk individuals, most with treated hypertension, MedDiets supplemented with extravirgin olive oil or nuts reduced 24-hour ambulatory BP, total cholesterol, and fasting glucose. http://www.clinicaltrials.gov.

    Full Text Available Introduction Knee osteoarthritis (OA is the most common articular disease. Different methods are used to alleviate the symptoms of patients with knee OA, including analgesics, physical therapy, exercise prescription, and intra-articular injections (glucocorticoids, hyaluronic acid [HA], etc. New studies have focused on modern therapeutic methods that stimulate cartilage healing process and improve the damage, including the use of platelet-rich plasma (PRP as a complex of growth factors. Due to the high incidence of OA and its consequences, we decided to study the long-term effect of intraarticular injection of PRP and HA on clinical outcome and quality of life of patients with knee OA. Method This non-placebo-controlled randomized clinical trial involved 160 patients affected by knee OA, grade 1–4 of Kellgren–Lawrence scale. In the PRP group ( n = 87, two intra-articular injections at 4-week interval were applied, and in the HA group ( n = 73, three doses of intra-articular injection at 1-week interval were applied. All patients were prospectively evaluated before and at 12 months after the treatment by Western Ontario and McMaster Universities Arthritis Index (WOMAC and SF-36 questionnaires. The results were analyzed using SPSS 16.1 software (RCT code: IRCT2014012113442N5. Results At the 12-month follow-up, WOMAC pain score and bodily pain significantly improved in both groups; however, better results were determined in the PRP group compared to the HA group ( P < 0.001. Other WOMAC and SF-36 parameters improved only in the PRP group. More improvement (but not statistically significant was achieved in patients with grade 2 OA in both the groups. Conclusion This study suggests that PRP injection is more efficacious than HA injection in reducing symptoms and improving quality of life and is a therapeutic option in select patients with knee OA who have not responded to conventional treatment.

    Full Text Available The aim of this study was to assess by means of cone-beam computed tomography (CBCT scans the transverse effects on the nasomaxillary complex in patients submitted to rapid maxillary expansion (RME using Haas expander in comparison to untreated individuals. This prospective controlled clinical study assessed 30 subjects (18 boys and 12 girls with mixed dentition and during pubertal growth. The treated group was submitted to RME with Haas expander, retention for six months and a six-month follow-up after removal. The control group matched the treated group in terms of age and sex distribution. CBCT scans were taken at treatment onset and one year after the expander was activated. Maxillary first molars (U6 width, right and left U6 angulation, maxillary alveolar width, maxillary basal width, palatal alveolar width, palatal base width, right and left alveolar angulation, palatal area, nasal base width, nasal cavity width and inferior nasal cavity area on the posterior, middle and anterior coronal slices were measured with Dolphin Imaging Software(r 11.5, except for the first two variables which were performed only on the posterior slice. All transverse dimensions increased significantly (P 0.05. Results suggest that increase of molar, maxillary, palatal and nasal transverse dimensions was stable in comparison to the control group one year after treatment with RME.

    This randomized, multicenter study compared the relative efficacy of renal denervation (RDN) versus pharmacotherapy alone in patients with true resistant hypertension and assessed the effect of spironolactone addition. We present here the 12-month data. A total of 106 patients with true resistant hypertension were enrolled in this study: 52 patients were randomized to RDN and 54 patients to the spironolactone addition, with baseline systolic blood pressure of 159±17 and 155±17 mm Hg and average number of drugs 5.1 and 5.4, respectively. Twelve-month results are available in 101 patients. The intention-to-treat analysis found a comparable mean 24-hour systolic blood pressure decline of 6.4 mm Hg, P=0.001 in RDN versus 8.2 mm Hg, P=0.002 in the pharmacotherapy group. Per-protocol analysis revealed a significant difference of 24-hour systolic blood pressure decline between complete RDN (6.3 mm Hg, P=0.004) and the subgroup where spironolactone was added, and this continued within the 12 months (15 mm Hg, P= 0.003). Renal artery computed tomography angiograms before and after 1 year post-RDN did not reveal any relevant changes. This study shows that over a period of 12 months, RDN is safe, with no serious side effects and no major changes in the renal arteries. RDN in the settings of true resistant hypertension with confirmed compliance is not superior to intensified pharmacological treatment. Spironolactone addition (if tolerated) seems to be more effective in blood pressure reduction. © 2015 American Heart Association, Inc.

    Aims To report the longer term outcomes following either a strategy of endovascular repair first or open repair of ruptured abdominal aortic aneurysm, which are necessary for both patient and clinical decision-making. Methods and results This pragmatic multicentre (29 UK and 1 Canada) trial randomized 613 patients with a clinical diagnosis of ruptured aneurysm; 316 to an endovascular first strategy (if aortic morphology is suitable, open repair if not) and 297 to open repair. The principal 1-year outcome was mortality; secondary outcomes were re-interventions, hospital discharge, health-related quality-of-life (QoL) (EQ-5D), costs, Quality-Adjusted-Life-Years (QALYs), and cost-effectiveness [incremental net benefit (INB)]. At 1 year, all-cause mortality was 41.1% for the endovascular strategy group and 45.1% for the open repair group, odds ratio 0.85 [95% confidence interval (CI) 0.62, 1.17], P = 0.325, with similar re-intervention rates in each group. The endovascular strategy group and open repair groups had average total hospital stays of 17 and 26 days, respectively, P < 0.001. Patients surviving rupture had higher average EQ-5D utility scores in the endovascular strategy vs. open repair groups, mean differences 0.087 (95% CI 0.017, 0.158), 0.068 (95% CI −0.004, 0.140) at 3 and 12 months, respectively. There were indications that QALYs were higher and costs lower for the endovascular first strategy, combining to give an INB of £3877 (95% CI £253, £7408) or €4356 (95% CI €284, €8323). Conclusion An endovascular first strategy for management of ruptured aneurysms does not offer a survival benefit over 1 year but offers patients faster discharge with better QoL and is cost-effective.

    Extracorporeal shock wave therapy (ESWT) is seen as a therapeutic option in the treatment of chronic supraspinatus tendinitis by some authors. To test whether ESWT comprising 3 x 2000 pulses with the positive energy flux density ED+ of 0.33 mJ/mm2 is clinically superior to a sham ESWT treatment, a prospective, randomized, single-blinded, placebo-controlled study with an independent observer was performed. Forty patients were treated either by verum ESWT or sham ESWT under local anesthesia. Target criteria were the age-corrected Constant score, pain at rest and during activity on a visual analogue scale, and subjective improvement. Patients who reported no subjective improvement after 12 weeks were deblinded and received verum ESWT if they had belonged to the placebo group (partial crossover). The results of the verum group lie within the range of results for ESWT published by other authors. Patients in the placebo group with local anesthetic showed equally good results. At 12 weeks, and 1 year after intervention, no difference could be found between the verum and placebo groups regarding Constant score, pain, shoulder function, or subjective improvement. The nonresponders to the placebo ESWT continued to show no improvement after receiving verum ESWT. This contradicts a specific ESWT effect. Based on the results of this placebo-controlled study, ESWT appears to have no clinically relevant effect on supraspinatus tendinitis. The study underlines the importance of a control group in evaluating new treatment methods for diseases with unknown natural history.

    Clinical studies on the outcome of adolescent depression beyond treatment trials are scarce. To investigate the impact of characteristics of the depressive episode and current comorbidity on the 1-year outcome of depression. A sample of 174 consecutive adolescent psychiatric outpatients (aged 13 through 19 years) and 17 school-derived matched controls, all with unipolar depressive disorders at baseline, were reinterviewed for DSM-IV Axis I and Axis II disorders at 12 months. The study was conducted between January 1998 and May 2002. The outpatients had equal recovery rate and episode duration but shorter time to recurrence than the controls. Among the outpatients, Axis II comorbidity predicted shorter time to recurrence (p = .02). Longer time to recovery was predicted by earlier lifetime age at onset for depression (p = .02), poor psychosocial functioning (p = .003), depressive disorder diagnosis (p

    We aimed to compare a combined oral contraceptive (COC) plus the antiandrogen spironolactone with the insulin sensitizer metformin in women with polycystic ovary syndrome (PCOS). We conducted a randomized, parallel, open-label, clinical trial comparing COC (30 μg of ethinylestradiol and 150 μg of desogestrel) plus spironolactone (100 mg/day) with metformin (850 mg b.i.d.) for one year in women with PCOS (EudraCT2008-004531-38). The composite primary outcome included efficacy (amelioration of hirsutism, androgen excess and menstrual dysfunction) and cardiometabolic safety (changes in the frequencies of disorders of glucose tolerance, dyslipidemia and hypertension). A complete anthropometric, biochemical, hormonal and metabolic evaluation was conducted every three months and data were submitted to intention-to-treat analyses. Twenty-four patients were assigned to COC plus spironolactone and 22 patients to metformin. Compared with metformin, COC plus spironolactone caused larger decreases in hirsutism score (mean difference 4.6 points, 95% CI: 2.6-6.7), total testosterone (1.1 nmol/L, 0.4-1.7), free testosterone (25 pmol/L, 12-39), androstenedione (5.5 nmol/L, 1.8-9.2) and dehydroepiandrosterone sulfate (2.7 μmol/L, 1.4-4.0). Menstrual dysfunction was less frequent with COC plus spironolactone (OR: 0.06, 95% CI: 0.02-0.23). No differences were found in frequencies of abnormal glucose tolerance (OR: 1.7, 95% CI: 0.7-4.4), dyslipidemia (OR: 0.6, 95% CI: 0.2-1.8) or hypertension (OR: 0.3, 95% CI: 0.5-2.0). No major adverse events occurred and biochemical markers were similarly safe with both treatments. COC plus spironolactone was more effective than metformin for symptoms of PCOS showing similar safety and overall neutral effects on cardiometabolic risk factors. © 2017 European Society of Endocrinology.

    The eruption guidance appliance (EGA) aims to correct sagittal and vertical occlusal relations concomitantly with alignment of the incisors. Few reports have been published on treatment effects with the EGA but no randomized studies have been available. The aim was to find out if 1 year active treatment time with EGA was sufficient for achieving normal occlusal relationships and dental alignment in 7- to 8-year-old children. Eligibility criteria for participants were: fully erupted upper central incisors, and Angle's Class I or Class II molar relationship combined with any of the following traits: deep bite, increased overjet ≥5mm, moderate anterior crowding with overjet ≥4mm. After screening of 148 children, 48 7- to 8-year-old children were recruited in the study. The participants were randomly assigned into a treatment group (N = 25) and a control group (N = 23). Children in the treatment group received treatment with the EGA for 1 year. The controls had no orthodontic treatment. Changes in overjet, overbite, Angle's Class, and crowding were used as primary outcome measures. Occlusal assessments were performed on dental casts obtained from all subjects at start of the study (T1) and after 1 year (T2). Lateral cephalograms were obtained from all subjects at T1 and from the treatment group at T2. All measurements on dental casts and cephalograms were carried out blinded. Forty-six children completed the study. Mean overjet and overbite decreased significantly in the treated subjects during 1 year, in contrast to a slight increase in the controls. Class II molar relationship decreased from 46 to 4 per cent in the treatment group, with no significant change in the control group. Mandibular anterior crowding decreased significantly in the treated subjects, while the controls showed a slight increase. In short term, the EGA seems to be effective in correcting increased overjet and overbite, Class II malocclusion, and lower anterior crowding in the early mixed

    Heart transplant recipients have lower exercise capacity and impaired cardiac function compared with the normal population. High-intensity interval training (HIIT) improves exercise capacity and cardiac function in patients with heart failure and hypertension, but the effect on cardiac function in stable heart transplant recipients is not known. Thus, we investigated whether HIIT improved cardiac function and exercise capacity in stable heart transplant recipients by use of comprehensive rest- and exercise-echocardiography and cardiopulmonary exercise testing. Fifty-two clinically stable heart transplant recipients were randomised either to HIIT (4 × 4 minutes at 85-95% of peak heart rate three times per week for eight weeks) or to control. Three such eight-week periods were distributed throughout one year. Echocardiography (rest and submaximal exercise) and cardiopulmonary exercise testing were performed at baseline and follow-up. One year of HIIT increased VO 2peak from 27.7 ± 5.5 at baseline to 30.9 ± 5.0 ml/kg/min at follow-up, while the control group remained unchanged (28.5 ± 7.0 vs. 28.0 ± 6.7 ml/kg per min, p HIIT. Whereas HIIT is feasible in heart transplant recipients and effectively improves exercise capacity, it does not alter cardiac systolic and diastolic function significantly. Thus, the observed augmentation in exercise capacity is best explained by extra-cardiac adaptive mechanisms.

    Root canal therapy (RCT) and tooth extraction have been conventional treatment options for management of human mature teeth with irreversible pulpitis. Excellent short-term treatment outcomes of vital pulp therapy with calcium-enriched mixture cement (VPT/CEM), as a new treatment option, on postoperative pain relief was demonstrated; if intermediate- and long-term treatment outcomes of the new treatment are also non-inferior compared to RCT, then VPT/CEM may become a viable treatment option for management of mature teeth with irreversible pulpitis. In 23 healthcare centers, 407 9- to 65-year-old patients were randomly allocated into two study arms including one-visit RCT (reference treatment; n = 202) and VPT/CEM (alternative treatment; n = 205). Six- and twelve-month clinical and radiographic successes were assessed. Mean follow-up times at 6- and 12-month follow-ups were "6.70 ± 0.68 and 6.72 ± 0.71 months" and "12.96 ± 0.67 and 12.90 ± 0.66 months" in the available cases of RCT and VPT/CEM arms, respectively. Favorable clinical success rates in the two study arms did not show statistical difference; however, the radiographic success rate in the VPT/CEM was significantly greater than RCT arm at the two follow-ups (P pulpitis. The performance of biomaterials such CEM cement may assist in the shift towards more biologic treatments. VPT/CEM may be a realistic alternative treatment for human mature molar teeth with symptoms of irreversible pulpitis; the use of VPT/CEM is highly beneficial for patients as well as general dentists.

    Antipsychotic drugs are limited in their ability to improve negative symptoms, quality of life, and medication adherence in patients with schizophrenia. The addition of nonpharmacological interventions like social skills training has a positive effect on medication adherence and decreases rehospitalization rates but is limited in improving patients' symptoms, aggressive behaviors, and quality of life. Aerobic exercise, especially Tai-chi, can potentially reduce psychopathological and negative symptoms, decrease aggressive behaviors, and improve quality of life. It is an ideal rehabilitation intervention for patients with schizophrenia. However, no study has investigated the effects of social skills training plus Tai-chi on outcomes among outpatients with schizophrenia. This study analyzes the effect of antipsychotics combined with community-based integrated interventions on outcomes of schizophrenia. In this study, a 24-session social skills training plus Tai-chi was used in community settings among patients with schizophrenia. A total of 244 patients were randomly assigned to medication treatment alone (MTA group) or community-based integrated intervention (CBII group), which accepted social skills training plus Tai-chi in addition to medication treatment. Generalized linear mixed models were used to evaluate the intervention effect (group effect), intervention effect over time (time effect), and interaction effect (group × time effect). t tests were used to evaluate between-group differences on clinical variables. Multiple linear regression analysis was used to analyze the differences between the intervention at 12 months and baseline for the Positive and Negative Syndrome Scale (PANSS) negative symptoms and quality of life-social domain. Compared with the MTA group, the CBII group had lower scores on PANSS (F = 17.312, p social domain of the World Health Organization Quality of Life Scale-Brief version (WHOQOL-BREF) from baseline to 12 months were significant

    Full Text Available Abstract Background The increased prevalence of overweight and obesity warrants preventive actions, particularly among people in transitional stages associated with lifestyle changes, such as occupational retirement. The purpose is to investigate the effect of a one year low-intensity computer-tailored energy balance programme among recent retirees on waist circumference, body weight and body composition, blood pressure, physical activity and dietary intake. Methods A randomised controlled trial was conducted among recent retirees (N = 413; mean age 59.5 years. Outcome measures were assessed using anthropometry, bio-impedance, blood pressure measurement and questionnaires. Results Waist circumference, body weight and blood pressure decreased significantly in men of the intervention and control group, but no significant between-group-differences were observed at 12 or at 24-months follow-up. A significant effect of the programme was only observed on waist circumference (-1.56 cm (95%CI: -2.91 to -0.21 at 12 month follow up among men with low education (n = 85. Physical activity and dietary behaviours improved in both the intervention and control group during the intervention period. Although, these behaviours changed more favourably in the intervention group, these between-group-differences were not statistically significant. Conclusions The multifaceted computer-tailored programme for recent retirees did not appear to be effective. Apparently the transition to occupational retirement and/or participation in the study had a greater impact than the intervention programme. Trial registration Clinical Trials NCT00122213.

    Regular physical exercise within structured lifestyle programs may improve weight status and minimize metabolic risk factors in childhood obesity. The aim of this study was to evaluate the effect of the one-year combined physical exercise/lifestyle program KLAKS on anthropometric and metabolic parameters and glycemic control in childhood obesity. 142 overweight/obese (BMI>90th percentile) candidates (7-18years) were enrolled, 115 participants completed the program. Anthropometrics and biochemical parameters were obtained at beginning and completion. An oral glucose tolerance test (OGTT) was performed in a subgroup of participants. Course of glucose and insulin levels within OGTT was correlated with several parameters and is reported here for those who completed the program. The mean standard deviation scores (SDS) decreased significantly for BMI, waist circumference, waist-to-height ratio (WHtR) and percentage body fat (all p≤0.01). Improved metabolic risk markers included mean glucose levels within an OGTT at follow-up compared to baseline (pexercise/lifestyle program KLAKS significantly improves markers of obesity and glycemic control. Impaired cardiometabolic risk markers, even subclinical, are also favorably influenced by program participation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Multivariate analyses of 205 positive control experiments in an AmpFℓSTR© Identifiler© STR kit were used to analyze the factors affecting peak heights at 16 loci. Peak heights were found to be highly correlated between loci and there was evidence for a difference in sensitivity of the two genetic analyzers in the blue channel. Heterozygous balance response at 10 loci was found to behave as a random variable following a beta-distribution with typical median values of 90%, without locus or genetic analyzer effect. Inter-locus balance at 16 loci was influenced by the blue channel effect and a temporal switch of unexplained origin. The implications of these results for the choice of minimum threshold values in quality control are discussed. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

    In Bratislava, one year ago, exactly in April 28, the privatization deal of a 66% stake in Slovenske elektrarne (SE) was finally closed. The Slovak government and the Italian company ENEL signed final documents and ENEL thus definitely entered into SE. In May 2006, Miroslav Pikus, a former CEO, was replaced by Marco Arcelli, who, as a regional manager for Slovakia, had been preparing the entry of ENEL into SE since March 2005. Not only did he sometimes cook for us, in his 'kitchen' but also there were prepared 160 investment projects, e.g the improvement of nuclear safety and resistance of the Bohunice power plant, electricity sale through the so-called 'virtual power plant', ensuring a non-attended operation in hydro power plants, reconstruction and modernization of the Orava and Dobsina hydro power plants.

  1. Magnesium diboride: one year on

    2002-01-01

    Last January physicists discovered that an innocuous compound that had been sitting on the shelf for decades was, in fact, a record-breaking intermetallic superconductor. At the end of 2000 superconductivity in metal alloys and compounds appeared to remain trapped by a glass ceiling. Over the previous 10 years the temperature at which certain oxide-based compounds - such as bismuth strontium calcium copper oxide and mercury barium calcium copper oxide - lost their resistance to electric current had soared to well over 100 K. Meanwhile, the transition temperature, Tc, for carbon-based materials, including alkali-doped carbon-60 compounds, had risen close to the boiling point of liquid nitrogen (77 K). During the same period, however, the superconducting transition temperature of intermetallic compounds (materials made solely of metals and metal-like elements) remained close to 20 K - as it had been since the mid-1960s. By February 2001 everything had totally changed. It was as if a firecracker had gone off in the tidy little ant hill of superconductivity research. For the first few months of 2001, groups all over the world raced to understand the properties of a new intermetallic superconductor. The substance that everyone was scrambling to buy or make, the substance that was causing this grand commotion, was magnesium diboride (Mg B 2 ). This seemingly innocuous binary compound, which had been present in many labs for over half a century, had been discovered to superconduct just below 40 K. Even though we already know an amazing amount about Mg B 2 , our knowledge of superconductivity in this compound is only one year old. There is therefore the very real potential to improve its critical properties. In a similar vein, it is almost certain that our understanding of this extreme example of intermetallic superconductivity will greatly improve over the next few years and may even reveal other extreme superconductors.

    Nothing to declare. To evaluate whether connective tissue grafts performed at implant placement could be effective in augmenting peri-implant soft tissues. Ten partially edentulous patients requiring at least one single implant in the premolar or molar areas of both sides of the mandible were randomised to have one side augmented at implant placement with a connective soft tissue graft harvested from the palate or no augmentation. After 3 months of submerged healing, abutments were placed and within 1 month definitive crowns were permanently cemented. Outcome measures were implant success, any complications, peri-implant marginal bone level changes, patient satisfaction and preference, thickness of the soft tissues and aesthetics (pink aesthetic score) evaluated by an independent and blinded assessor 1 year after loading. One year after loading, no patients dropped out, no implants failed and no complications occurred. Both groups lost statistically significant amounts of peri-implant bone 1 year after loading (0.8 mm in the grafted group and 0.6 mm in the non-grafted group), but there was no statistically significant difference between groups. Soft tissues at augmented sites were 1.3 mm thicker (P Connective tissue grafts are effective in increasing soft tissue thickness, thus improving aesthetics. Longer follow-ups are needed to evaluate the stability of peri-implant tissues over time.

    About one year ago, after 18 years of business as a wholly owned affiliate of Exxon Corporation, Exxon Nuclear Company was acquired by Siemens/KWU and its name was changed to Advanced Nuclear Fuels Corporation (ANF). This profile describes the status of ANF one year later, principally from the European perspective but with some mention of ANF's worldwide operations to provide a balanced picture. After one year of operation as an affiliate of Siemens/KWU, ANF's role remains as an independent international supplier of nuclear fuel and services to utilities in Europe, the USA and the Far East, but with substantially augmented capabilities resulting from the new affiliation

    Full Text Available The aim of this study was to compare the effects of static stretching, proprioceptive neuromuscular facilitation (PNF stretching and Mulligan technique on hip flexion range of motion (ROM in subjects with bilateral hamstring tightness. A total of 40 students (mean age: 21.5±1.3 years, mean body height: 172.8±8.2 cm, mean body mass index: 21.9±3.0 kg • m-2 with bilateral hamstring tightness were enrolled in this randomized trial, of whom 26 completed the study. Subjects were divided into 4 groups performing (I typical static stretching, (II PNF stretching, (III Mulligan traction straight leg raise (TSLR technique, (IV no intervention. Hip flexion ROM was measured using a digital goniometer with the passive straight leg raise test before and after 4 weeks by two physiotherapists blinded to the groups. 52 extremities of 26 subjects were analyzed. Hip flexion ROM increased in all three intervention groups (p<0.05 but not in the no-intervention group after 4 weeks. A statistically significant change in initial–final assessment differences of hip flexion ROM was found between groups (p<0.001 in favour of PNF stretching and Mulligan TSLR technique in comparison to typical static stretching (p=0.016 and p=0.02, respectively. No significant difference was found between Mulligan TSLR technique and PNF stretching (p=0.920. The initial–final assessment difference of hip flexion ROM was similar in typical static stretching and no intervention (p=0.491. A 4-week stretching intervention is beneficial for increasing hip flexion ROM in bilateral hamstring tightness. However, PNF stretching and Mulligan TSLR technique are superior to typical static stretching. These two interventions can be alternatively used for stretching in hamstring tightness.

    Full Text Available Objective The aim of the present study was to determine differences between male and female type 2 diabetic patients concerning body weight, metabolic control, insulin requirement and prevalence of vascular diseases during the first year insulin therapy. Patients and Methods We investigated 102 newly insulin-treated type 2 diabetic patients (60 female with secondary sulfonylurea failure. Observation period was the first year insulin therapy. We compared BMI, HbA1c, lipids and insulin requirement at the begin and after one year, C-peptide and prevalence of vascular diseases at the start of insulin therapy. Results At the start of insulin substitution, omen had a higher BMI (27 + 3 versus 25 + 3; p < 0.05. Women also required a higher insulin dose than did men (28 + 6 versus 24 + 6 IU/day Mean HbA1c and cholesterol levels were similar in both groups whereas triglycerides were higher in women (244 + 88 versus 203 + 76 mg/dl; p < 0.05. Both groups achieved a similar gain in body weight after one year (+2.5% versus +2.6%; NS. HbA1c decreased from 9.2 + 1.1 to 7.4% + 0.9% (–19% in women and from 9.4 + 1.1 to 7.5% + 1.0% (–20% in men. The prevalence of vascular diseases was not significantly different in both groups. Conclusions At the start of insulin therapy female type 2 diabetic patients showed a significant higher BMI and a higher insulin requirement than male patients. The metabolic control was similar in men and women, only the triglycerides were higher in the female patients. Weight gain and increase of needed insulin as well as prevalence of macroangiopathy were the same in both groups.

    Does the effect of one-day simulation team training in obstetric emergencies decline within one year? A post-hoc analysis of a multicentre cluster randomised controlled trial. J van de Ven, AF Fransen, E Schuit, PJ van Runnard Heimel, BW Mol, SG Oei OBJECTIVE: To investigate whether the effect of a one-day simulation-based obstetric team training on patient outcome changes over time. Post-hoc analysis of a multicentre, open, randomised controlled trial that evaluated team training in obstetrics (TOSTI study).We studied women with a singleton pregnancy beyond 24 weeks of gestation in 24 obstetric units. Included obstetric units were randomised to either a one-day, multi-professional simulation-based team training focusing on crew resource management in a medical simulation centre (12 units) or to no team training (12 units). We assessed whether outcomes differed between both groups in each of the first four quarters following the team training and compared the effect of team training over quarters. Primary outcome was a composite outcome of low Apgar score, severe postpartum haemorrhage, trauma due to shoulder dystocia, eclampsia and hypoxic-ischemic encephalopathy. During a one year period after the team training the rate of obstetric complications, both on the composite level and the individual component level, did not differ between any of the quarters. For trauma due to shoulder dystocia team training led to a significant decrease in the first quarter (0.06% versus 0.26%, OR 0.19, 95% CI 0.03 to 0.98) but in the subsequent quarters no significant reductions were observed. Similar results were found for invasive treatment for severe postpartum haemorrhage where a significant increase was only seen in the first quarter (0.4% versus 0.03%, OR 19, 95% CI 2.5-147), and not thereafter. The beneficial effect of a one-day, simulation-based, multiprofessional, obstetric team training seems to decline after three months. If team training is further evaluated or

    The Saphenous Vein Versus Right Internal Thoracic Artery as a Y-Composite Graft (SAVE RITA) trial was designed to evaluate the noninferiority of the saphenous vein (SV) compared with the right internal thoracic artery ([R]ITA) used as a Y-composite graft. A total of 224 patients who had undergone off-pump revascularization for multivessel coronary artery disease using the SV or RITA as a Y-composite graft based on the in situ left ITA were assigned randomly to the SV Y-composite graft (SV group, n = 112) or free RITA Y-composite graft (RITA group, n = 112). The primary endpoint was the 1-year angiographic patency rate of the second limb conduits (SV or RITA). Postoperative 1-year coronary angiograms were performed in 215 patients (SV group, 108; RITA group, 107). The overall graft patency rate was 97.4% (745 of 765) at 1 year (97.9% in the SV group vs 96.9% in the RITA group, P = .362). The primary endpoint of the study, the 1-year patency rate of the SV composite grafts, was 97.1% (238 of 245) and was noninferior to that of the RITA composite grafts (97.1% [198 of 204]) with a 95% lower confidence limit of -2.6% (P RITA composite grafts in terms of the 1-year angiographic patency rates.

    De novo sirolimus in calcineurin inhibitor-free regimens, although potentially useful to improve early renal function, are complicated by various drug-related side effects. We report a prospective open-label, multicenter, randomized trial to evaluate early conversion from a CsA-based to a sirolimus (SRL)-based regimen 10 to 24 days after renal transplantation. Of the 196 patients, 141 patients with a low-to-moderate immunological risk were eligible to be converted to SRL or to continue CsA. All patients received antithymocyte globulin-F single-bolus induction, mycophenolate mofetil, and steroids. The primary endpoint, renal function determined by S-creatinine and estimated glomerular filtration rate calculated by Nankivell formula at 12 months was significantly better in the SRL group (1.51+/-0.59 vs. 1.87+/-0.98 mg/dL or 64.5+/-25.2 vs. 53.4+/-18.0 mL/min/1.73 m). Patient survival, graft survival, and incidence of biopsy-proven acute rejection after conversion were not statistically different. Drug discontinuations were significantly higher in the SRL group (36.2% vs. 19.7%). Significantly, more patients in the SRL group reported acne, aphtous, and temporary hyperlipidemia, whereas cytomegalovirus viremia was significantly decreased (7.3% vs. 28.2%). Early conversion to a calcineurin inhibitor-free regimen with SRL in combination with mycophenolate mofetil may be a useful strategy to improve renal function. The identification of appropriate candidates and safe management of SRL-related adverse events will be a key to avoid the high rate of dropouts, which currently limit the broad applicability of this protocol.

    Purpose We compared outcomes of the U- and H-type approaches of the tension-free vaginal tape (TVT)-Secur procedure for the treatment of female stress urinary incontinence (SUI). Materials and Methods From March 2007 to July 2008, 115 women with SUI underwent TVT-Secur by a single surgeon. Patients were randomly assigned to either the U- or the H-type approach. After 12 months, postoperative changes in the Sandvik questionnaire, incontinence quality of life questionnaire (I-QoL), Bristol female lower urinary tract symptoms-scored form (BFLUTS-SF), and postoperative patient satisfaction were evaluated. Cure was regarded as no leakage on the Sandvik questionnaire. Complications were also evaluated. Results Of 115 women, 53 were treated with the U approach, and 62 women were treated with the H approach. At 12 months, 88.7% of those treated with the U approach and 87.1% of those treated with the H approach were cured (p=0.796). The I-QoL and filling, incontinence, sexual function, and QoL sum (BFLUTS-SF) scores were improved with both approaches, and there were no significant differences in the degree of improvement between approaches. Approximately 83.7% and 82.9% of the women treated with the U and H approaches, respectively, were satisfied with the outcome (p=0.858). There were 3 cases of intra-operative vaginal wall perforation in the H-type group. Immediate postoperative retention was observed in 2 women in the U-type group and 1 woman in the H-type group. One woman in the U-type group underwent tape releasing and cutting procedures for persistent large post-void residuals. Conclusions The U- and the H-type approaches of the TVT-Secur procedure provided comparable effectiveness for the treatment of female SUI. PMID:20428427

    We report a case of advanced pancreatic cancer with liver and lung metastases that was well controlled over one year by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion in an outpatient setting. The patient was a 74-year-old woman. Chief complaints were back pain and anorexia. She was diagnosed with pancreas cancer with liver and lung metastases at the time of first visit. We started systemic chemotherapy with gemcitabine 1 g/body and 5-FU 1 g/body alternately every other week on an outpatient basis. At 1.5 months (M) after initiation of chemotherapy, we started radiation therapy to the main tumor at a total dose of 40 Gy. After radiation, chemotherapy was resumed. As a result, the size of the main tumor decreased but metastatic liver tumors got larger. Then we changed to combination therapy with systemic chemotherapy (gemcitabine and 5-FU) and hepatic arterial infusion (5-FU weekly). Liver metastases almost disappeared after 7.5 M. Despite all these treatments, however, the number of metastatic lung tumors increased. The patient was hospitalized for 15 M and died after 17 M. We focused on and succeeded in the prolongation of lifetime and maintenance of QOL by combination therapy with systemic chemotherapy, radiation and hepatic arterial infusion therapy.

    Four human subjects recorded their wake-up and to-sleep times for one year each. The data were plotted to display individual circadian rhythms and the data were analyzed statistically. First, individuals had characteristic patterns in which visible changes in the patterns were observed mainly when time zones were changed because of travel. Second, the months with the latest wake-up and latest to-sleep times concentrated around the winter solstice; the months with the earliest wake-up and earliest to-sleep times concentrated around the fall equinox. Third, new moon versus full moon days were not different. Fourth, one-hour changes between standard and daylight savings time in the USA were reflected by near one-hour changes in two subjects, but not in a third. Fifth, weekend delays in wake-up time (0.8-1.6 hours), weekend delays in to-sleep time (0.1-0.5 hours), and shorter weekend awake time (0.8-1.3 hours) were observed. Sixth, throughout the year, wake-up times were close to the time of sunrise, but to-sleep times were several hours past sunset.

    Trousseau syndrome carries a poor prognosis and controlling thrombosis is difficult. In this case, the administration of anticancer therapy allowed use to control the patient's thrombosis. Therefore, this case highlights the importance of treating cancer in patients with Trousseau syndrome. In addition, the FDP and D-dimer levels changed in parallel with changes in the CEA level, which suggests that the activity of cancer is related to an internal thrombotic tendency. Hence, changes in the FDP and D-dimer values are associated with the efficacy of treatment with EGFR tyrosine kinase inhibitors and chemotherapy and may function as markers of recurrence.

    Purpose: To better analyze how whole-brain radiotherapy (WBXRT) affects long-term tumor control and toxicity from the initial stereotactic radiosurgery (SRS) for brain metastases, we studied these outcomes in patients who had survived at least 1 year from SRS. Methods and Materials: We evaluated the results of gamma knife radiosurgery for 160 brain metastases in 110 patients who were followed for a median of 18 months (range, 12-122 months) after SRS. Eighty-two patients had a solitary brain metastasis and 28 patients had multiple metastases. Seventy patients (116 tumors) were treated with initial radiosurgery and WBXRT, whereas 40 patients (44 lesions) initially received radiosurgery alone. Median treatment volume was 1.9 cc in the entire group, 2.3 cc in the WBXRT group, and 1.6 cc in the SRS alone group. Median tumor dose was 16 Gy (range, 12-21 Gy). Results: At 1, 3, and 5 years, local tumor control was 84.1% ± 5.5%, 68.6% ± 8.7%, and 68.6% ± 8.7% with SRS alone compared with 93.1% ± 2.4%, 87.7% ± 4.9%, and 65.7% ± 10.2%. with concurrent WBXRT and SRS (p = 0.0228, univariate). We found that WBXRT improved local control in patient subsets tumor volume ≥2 cc, peripheral dose ≤16 Gy, single metastases, nonradioresistant tumors, and lung cancer metastases (p = 0.0069, 0.0080, 0.0083, 0.0184, and 0.0348). Distal intracranial failure developed at 1, 3, and 5 years in 26.0% ± 7.1%, 74.5% ± 9.4%, and 74.5% ± 9.4% with SRS alone compared with 20.7% ± 4.9%, 49.0% ± 8.7%, and 61.8% ± 12.8% with concurrent WBXRT and SRS (p = 0.0657). We found a trend for improved distal intracranial control with WBXRT for only nonradioresistant tumors (p = 0.054). Postradiosurgery complications developed in 2.8% ± 1.2% and 10.7% ± 3.5% at 1 and 3-5 years and was unaffected by WBXRT (p = 0.7721). WBXRT did not improve survival in the entire series (p = 0.5027) or in any subsets. Conclusions: In this retrospective study of 1-year survivors of SRS for brain metastases, the

    After one year of systems engineering at the Superconducting Super Collider (SSC), the project baseline of costs, schedule milestones, and top-level (point design) physics parameters has been accepted by the Department of Energy (DOE). This paper describes the role of systems engineering in developing the baseline and in establishing requirements specifications, change control, and methods of tracking to a baseline. The differences between the Department of Defense and DOE--specifically at the SSC Laboratory (SSCL)--in application of systems engineering disciplines and tools are discussed. The aim of the paper is to inform participating industries of the anticipated requirements format and of the emphasis that will be placed on physics requirements as opposed to procedures. Industry subcontractors should have a better understanding of the systems engineering expected by the SSCL. 3 figs

    One year ago, the authors of this article reported in this journal on the malaria situation in Sri Lanka prior to the tsunami that hit on 26 December 2004, and estimated the likelihood of a post-tsunami malaria outbreak to be low. Malaria incidence has decreased in 2005 as compared to 2004 in most...... districts, including the ones that were hit hardest by the tsunami. The malaria incidence (aggregated for the whole country) in 2005 followed the downward trend that started in 2000. However, surveillance was somewhat affected by the tsunami in some coastal areas and the actual incidence in these areas may...... have been higher than recorded, although there were no indications of this and it is unlikely to have affected the overall trend significantly. The focus of national and international post tsunami malaria control efforts was supply of antimalarials, distribution of impregnated mosquito nets...

    Full Text Available This paper investigates the dynamic output feedback control for nonlinear networked control systems with both random packet dropout and random delay. Random packet dropout and random delay are modeled as two independent random variables. An observer-based dynamic output feedback controller is designed based upon the Lyapunov theory. The quantitative relationship of the dropout rate, transition probability matrix, and nonlinear level is derived by solving a set of linear matrix inequalities. Finally, an example is presented to illustrate the effectiveness of the proposed method.

    Epidural steroid injections (ESIs) are commonly used for treatment of symptomatic lumbar spinal stenosis (LSS). ESIs are generally administered after failure of conservative therapy. For LSS patients suffering from neurogenic claudication, the mild® procedure provides an alternative to ESIs via minimally invasive lumbar decompression. Both ESIs and mild offer interventional pain treatment options for LSS patients experiencing neurogenic claudication refractory to more conservative therapies. Prospective, multi-center, randomized controlled, clinical study. Twenty-six interventional pain management centers throughout the United States. To compare patient outcomes following treatment with either mild or ESIs in LSS patients with neurogenic claudication and having verified ligamentum flavum hypertrophy. Study participants include Medicare beneficiaries who meet study inclusion/exclusion criteria. Eligible patients will be randomized in a 1:1 ratio to one of 2 treatment arms, mild (treatment group) or ESI (control group). Each study group will include approximately 150 patients who have experienced neurogenic claudication symptoms for ≥ 3 months duration who have failed to respond to physical therapy, home exercise programs, and oral analgesics. Those randomized to mild are prohibited from receiving lumbar ESIs during the study period, while those randomized to ESI may receive ESIs up to 4 times per year. Patient assessments will occur at baseline, 6 months, and one year. An additional assessment will be conducted for the mild patient group at 2 years. The primary efficacy outcome measure is the proportion of Oswestry Disability Index (ODI) responders from baseline to one year follow-up in the treatment group (mild) versus the control group (ESI). ODI responders are defined as those patients achieving the validated Minimal Important Change (MIC) of ≥ 10 point improvement in ODI from baseline to follow-up as a clinically significant efficacy threshold.

    Limited studies have investigated relationships in psychosocial outcomes between adolescents who are obese and their parents and how psychosocial outcomes change during participation in a physical activity and healthy eating intervention. This study examined both adolescent and parent psychosocial outcomes while participating in a one - year multi-disciplinary family-based intervention: Curtin University's Activity, Food, and Attitudes Program (CAFAP). Following a waitlist control period, the intervention was delivered to adolescent (n = 56, ages 11-16) and parent participants over 8 weeks, with one-year maintenance follow-up. Adolescent depression and quality of life, family functioning, and parent depression, anxiety, and stress were assessed at six time points: baseline and prior to intervention (e.g., waitlist control period), immediately following intervention, and at 3, 6, and 12 months post-intervention. Relationships between adolescent and parent psychosocial outcomes were assessed using Spearman correlations and changes in both adolescent and parent outcomes were assessed using linear mixed models. Changes in adolescent psychosocial outcomes were compared to changes in behavioural (physical activity and healthy eating) and physical (weight) outcomes using independent samples t-tests. The majority of psychosocial outcomes were significantly correlated between adolescents and parents across the one-year follow-up. Adolescent depression, psychosocial and physical quality of life outcomes significantly improved before or following intervention and were maintained at 6-months or one-year follow-up. Parent symptoms of depression, anxiety, and stress were reduced during waitlist and primarily remained improved. Changes in adolescent psychosocial outcomes were shown to be partially associated with behavioural changes and independent of physical changes. Adolescents in CAFAP improved psychosocial and physical quality of life and reversed the typical

    To assess recent trends in the prevalence and quality of reporting of randomized controlled trials (RCTs) in 4 otolaryngology journals. Methodology and reporting analysis. Randomized controlled trials in 4 otolaryngology journals. All RCTs published from 2011 to 2013 in 4 major otolaryngology journals were examined for characteristics of study design, quality of design and reporting, and funding. Of 5279 articles published in 4 leading otolaryngology journals from 2011 to 2013, 189 (3.3%) were RCTs. The majority of RCTs were clinical studies (86%), with the largest proportion consisting of sinonasal topics (31%). Most interventions were medical (46%), followed by surgical (38%) and mixed (16%). In terms of quality, randomization method was reported in 54% of RCTs, blinding in 33%, and adverse events in 65%. Intention-to-treat analysis was used in 32%; P values were reported in 87% and confidence intervals in 10%. Research funding was most often absent or not reported (55%), followed by not-for-profit (25%). Based on review of 4 otolaryngology journals, RCTs are still a small proportion of all published studies in the field of otolaryngology. There seem to be trends toward improvement in quality of design and reporting of RCTs, although many quality features remain suboptimal. Practitioners both designing and interpreting RCTs should critically evaluate RCTs for quality. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    Previous work has shown patients commonly misuse adrenaline autoinjectors (AAI). It is unclear whether this is due to inadequate training, or poor device design. We undertook a prospective randomized controlled trial to evaluate ability to administer adrenaline using different AAI devices. We allocated mothers of food-allergic children prescribed an AAI for the first time to Anapen or EpiPen using a computer-generated randomization list, with optimal training according to manufacturer's instructions. After one year, participants were randomly allocated a new device (EpiPen, Anapen, new EpiPen, JEXT or Auvi-Q), without device-specific training. We assessed ability to deliver adrenaline using their AAI in a simulated anaphylaxis scenario six weeks and one year after initial training, and following device switch. Primary outcome was successful adrenaline administration at six weeks, assessed by an independent expert. Secondary outcomes were success at one year, success after switching device, and adverse events. We randomized 158 participants. At six weeks, 30 of 71 (42%) participants allocated to Anapen and 31 of 73 (43%) participants allocated to EpiPen were successful - RR 1.00 (95% CI 0.68-1.46). Success rates at one year were also similar, but digital injection was more common at one year with EpiPen (8/59, 14%) than Anapen (0/51, 0%, P = 0.007). When switched to a new device without specific training, success rates were higher with Auvi-Q (26/28, 93%) than other devices (39/80, 49%; P adrenaline administration. Success rates were low with several devices, but were high using the audio-prompt device Auvi-Q. © 2015 The Authors Allergy Published by John Wiley & Sons Ltd.

    To assess the outcome of children older than one year with neuroblastoma treated at King Abdul-Aziz Medical City, Jeddah, Kingdom of Saudi Arabia. We retrospectively reviewed the files of 52 children older than one year with neuroblastoma (NBL) treated at our center between September 1987 and May 2003. Treatment consisted of OPEC chemotherapy regimen (vincristine, cisplatin, etoposide, and cyclophosphamide) or alternating OPEC/OJEC (carboplatin in place of cisplatin), surgical resection +/- radiotherapy (RT). No patient received high dose therapy (HDT). Thirty-four patients (65%) were stage 4, 12 (23%) stage 3, and 6 (11%) stage 2. Three stage 2 patients were treated with surgery only, all are alive in complete remission (CR). All stage 3 and 4 patients were treated with chemotherapy and surgery +/- RT. After induction chemotherapy, CR was achieved in 17 patients (32%) and partial remission in 10 (19%). Complete surgical resection was possible in 11 patients (22%). Disease recurrence or progression occurred in 27 patients (51%). With a median follow-up of 24 months (range 4-120), the 2-year event free survival was 10%, 82%, and 87% and the overall survival was 12%, 83%, and 100% for stage 4, 3, and 2. Children older than one year with localized NBL have good prognosis compared to those with stage 4. The use of HDT may improve the outcome in the latter group. Toxicity was significant, and adoption of risk-stratified treatment may help to reduce treatment complications.

    School-based drug prevention curricula constitute the nation's most prevalent strategy to prevent adolescent drug use. We evaluated the effects of one such curriculum, Project ALERT, on adolescent substance use. In particular, we sought to determine if a single effect on 30-day alcohol use, noted shortly following the completion of the 2-year program, could be detected 1 year later. We also looked for delayed effects on other outcomes of interest, namely lifetime alcohol use, and 30-day and lifetime use of cigarettes, marijuana, and inhalants. We employed a randomized controlled trial that used school as the unit of assignment. Thirty-four schools with grades 6-8 from 11 states completed the study. Seventy-one Project ALERT instructors taught 11 core lessons to sixth graders and 3 booster lessons to seventh graders. Students were assessed prior to the onset of the intervention, as sixth graders, after the completion of the 2-year curriculum, as seventh graders, and again 1 year later as eighth graders. This paper examines data from the pretest and final posttest. Using hierarchical nonlinear modeling, we found that our earlier effect on 30-day alcohol use did not persist. Further, we continued to find no effects for lifetime alcohol use and both the lifetime and 30-day use of cigarettes, marijuana, and inhalants. Our findings do not support the long-term effectiveness of Project ALERT, when delivered to sixth graders.

    To investigate levels and predictors of change in dimensions of burnout after an intervention for stressed doctors. Cohort study followed by self reported assessment at one year. Norwegian resource centre. 227 doctors participating in counselling intervention, 2003-5. Counselling (lasting one day (individual) or one week (group based)) aimed at motivating reflection on and acknowledgement of the doctors' situation and personal needs. Levels of burnout (Maslach burnout inventory) and predictors of reduction in emotional exhaustion investigated by linear regression. 185 doctors (81%, 88 men, 97 women) completed one year follow-up. The mean level of emotional exhaustion (scale 1-5) was significantly reduced from 3.00 (SD 0.94) to 2.53 (SD 0.76) (t=6.76, Ppsychotherapy, from 20% (36/182) to 53% (97/182). In the whole cohort, reduction in emotional exhaustion was independently associated with reduced number of work hours/week (beta=0.17, P=0.03), adjusted for sex, age, and personality dimensions. Among men "satisfaction with the intervention" (beta=0.25, P=0.04) independently predicted reduction in emotional exhaustion. A short term counselling intervention could contribute to reduction in emotional exhaustion in doctors. This was associated with reduced working hours for the whole cohort and, in men, was predicted by satisfaction with the intervention.

We found that wheat flour transamidation inhibited IFN-γ secretion by intestinal T cells from CD patients. Herein, the primary endpoint was to evaluate the ability of transamidated gluten to maintain GFD CD patients in clinical remission. Secondary endpoints were efficacy in prevention of the inflammatory response and safety at the kidney level, where reaction products are metabolized. In a randomized single blinded, controlled 90-day trial, 47 GFD CD patients received 3.7 g/day of gluten from nontransamidated (12 or transamidated (35 flour. On day 15, 75% and 37% of patients in the control and experimental groups, respectively, showed clinical relapse (=0.04 whereas intestinal permeability was mainly altered in the control group (50% versus 20%, =0.06.

    This article addresses the continued need for the behavior change process that must be managed long after materiel requirements planning (MRP II) implementation. Mason & Hanger, Pantex Plant is the final assembly and dismantlement facility for all United States nuclear weapons. On October 1, 1990, Mason & Hanger implemented a full production cutover to MRP II. One year later, following class A certification, the MRP II implementation team is still actively managing the change process through education and training programs and overall continuous improvement initiatives. Actual behavior change problems are identified together with the proven solutions implemented in a government-owned, contractor-operated facility environment. Performance measurements ranging from senior management planning to shop floor accomplishments and cost variance reports are shown as normal management tools used to identify target improvement areas.

    Full Text Available Abstract Journal of Foot and Ankle Research was launched one year ago, and a number of its key achievements are highlighted in this editorial. Although the journal is underpinned by professional bodies associated with the podiatry professions in the UK and Australasia, its content is aimed at the wider foot and ankle research community. Nevertheless, the journal's achievements over the past year reflect the development of research in the profession of podiatry. From this perspective, the journal may be viewed as contributing to the overall attainment of some of the profession's key goals and strategic aims over the last decade, across the UK and Australasia. The journal has also witnessed policy changes in the last year, and these are discussed - notably, the decision not to accept case reports for publication. We also report on a few of the key metrics, providing readers with a summary of the journal's performance over the last year.

    To analyse the relation between unemployment and the psychological distress of mothers one year after childbirth. Multicentric survey concerning births occurring between September 1993 and July 1994. In France: two maternity units in the Parisian area and one in Champagne-Ardennes, in the east of France, comprising both urban and rural areas. Primipara and secondipara women were interviewed three times: at birth by a face to face interview, five months and 12 months after the birth, by postal questionnaires, with a 83% response rate for the two postal questionnaires. The analysis includes 632 women who answered all three stages of the survey. Psychological distress was mainly assessed one year after birth by the 12-item General Health Questionnaire. After adjustment for unwanted pregnancy, marital conflicts, marital status, hospitalisation of the baby during the last year, lack of confiding relationship, depressive or anxious troubles before pregnancy, age, educational level and parity, unemployed women had an excess of psychological distress compared with employed women (OR = 1.87; 95% CI = 1.12, 3.13). The ratios for housewives were very close to those of employed women. Among the unemployed women, 60% had recently been without a job, since a few months before or after the birth. An excess of psychological distress among unemployed compared with employed women was observed in all social groups defined by the current or last occupation, but with various extents. Psychological distress was specially linked to the employment status in the group of women with the more qualified occupations. Even after a birth, when women are very much involved in their maternal role, those seeking a job have worse mental health than those in a stable situation, either employed or housewives. In France, the unemployment rate among young women is high. It is specially important that social regulations protecting employment during and after pregnancy are adequately applied. Employers

    Patients on sick leave due to work-related stress often present with cognitive impairments. The aim of this prospective cohort study was to examine the long-term consequences of prolonged work-related stress in terms of cognitive functioning one year after initial professional care seeking. We tested a group of patients with work-related stress with a comprehensive neuropsychological test battery at two occasions, one year apart. At both time points, we compared the performance of patients with healthy controls matched pairwise on sex, age and length of education. This paper presents the results from the one-year follow-up. When adjusting for practice effects, patients improved on measures of prospective memory and processing speed. However, patients continued to perform worse than controls on all tests, though only half of the comparisons reached statistical significance. The effect sizes of the differences between the two groups at one-year follow-up were small to medium. In conclusion, former patients with prolonged work-related stress improved, but they continued to perform worse than controls after one year. In the acute phase, the largest impairments were related to executive function and mental speed but at follow-up memory impairments also became apparent.

    To compare individual efficacy and additive effects of pain control interventions in preterm neonates. Randomized controlled trial. Level-3 University affiliated neonatal intensive care unit. 200 neonates (26-36 wk gestational age) requiring heel-prick for bedside glucose assessment. Exclusion criteria were neurologic impairment and critical illness precluding study interventions. Neonates were randomly assigned to Kangaroo mother care with Music therapy, Music therapy, Kangaroo Mother care or Control (no additional intervention) groups. All groups received expressed breast milk with cup and spoon as a baseline pain control intervention. Assessment of pain using Premature Infant Pain Profile (PIPP) score on recorded videos. The mean (SD) birth weight and gestational age of the neonates was 1.9 (0.3) kg and 34 (2.3) wk, respectively. Analysis of variance showed significant difference in total PIPP score across groups (P<0.001). Post-hoc comparisons using Sheffe's test revealed that the mean (SD) total PIPP score was significantly lower in Kangaroo mother care group [7.7 (3.9) vs. 11.5 (3.4), 95% CI(-5.9, -1.7), P<0.001] as well as Kangaroo mother care with Music therapy group [8.5 (3.2) vs. 11.5 (3.4), 95%CI (-5.1, -0.9), P=0.001] as compared to Control group. PIPP score was not significantly different between Control group and Music therapy group. Kangaroo mother care with and without Music therapy (with expressed breast milk) significantly reduces pain on heel-prick as compared to expressed breast milk alone. Kangaroo mother care with expressed breast milk should be the first choice as a method for pain control in preterm neonates.

    Full Text Available BACKGROUND: Healthcare costs, particularly pharmaceutical costs, are a dominant issue for most healthcare organizations, but it is unclear if randomized controlled trials (RCTs routinely discuss costs. Our objective was to assess the frequency and factors associated with the inclusion of costs in RCTs. METHODS AND FINDINGS: We randomly sampled 188 RCTs spanning three years (2003-2005 from six high impact journals. The sample size for RCTs was based on a calculation to estimate the inclusion of actual drug costs with a precision of +/-3%. Two reviewers independently extracted cost data and study characteristics. Frequencies were calculated and potential characteristics associated with the inclusion of costs were explored. Actual drug costs were included in 4.7% (9/188 of RCTs; any actual costs were included in 7.4% (14/188 of RCTs; and any mention of costs was included in 27.7% (52/188 of RCTs. As the amount of industry funding increased across RCTs, from non-profit to mixed to fully industry funded RCTs, there was a statistically significant reduction in the number of RCTs with any actual costs (Cochran-Armitage test, p = 0.005 and any mention of costs (Cochran-Armitage test, p = 0.02. Logistic regression analysis also indicated funding was associated with the inclusion of any actual cost (OR = 0.34, p = 0.009 or any mention of costs (OR = 0.63, p = 0.02. Journal, study conclusions, study location, primary author's country and product age were not associated with inclusion of cost information. CONCLUSION: While physicians are encouraged to consider costs when prescribing drugs for their patients, actual drug costs were provided in only 5% of RCTs and were not mentioned at all in 72% of RCTs. Industry funded trials were less likely to include cost information. No other factors were associated with the inclusion of cost information.

    Full Text Available The physical shape of vocal tract and its formant (resonant frequencies are directly related. The study of this functional connectivity is essential in speech therapy practice with children. Most of the perceived children’s speech anomalies can be explained on a physical level: malfunctioning movement of articulation organs. The current problem is that there is no enough data on the anatomical shape of children’s vocal tract to create its acoustic model. Classical techniques for vocal tract shape imaging (X-ray, magnetic resonance, etc. are not appropriate for children. One possibility is to start from the shape of the adult vocal tract and correct it based on anatomical, morphological and articulatory differences between children and adults. This paper presents a method for vocal tract shape estimation of the child aged one year. The initial shapes of the vocal tract refer to the Russian vowels spoken by an adult male. All the relevant anatomical and articulation parameters, that influence the formant frequencies, are analyzed. Finally, the hypothetical configurations of the children’s vocal tract, for the five vowels, are presented.

    The therapeutical effectiveness of gestrinone in endometriosis treatment, as well as its long term side effects, were evaluated. Prospective, clinical trial. At "Dr. Alejandro Castanedo Kimball" Hospital (PEMEX). Salamanca, Guanajuato. México. Thirty women with laparoscopically confirmed endometriosis, were studied. Subjects received 2.5 mg. of gestrinone two times per week for 6 months. Laparoscopy was performed before treatment, and clinical response was determined by second laparoscopy after 6 months. The pregnancy rate, frequency of side effects and recurrence of symptoms were determined. Median total endometriosis scores and symptoms decreased significantly after treatment. Four pregnancies were observed after treatment. The principal side effects were: ponderal increase, changes in the voice and hirsutism. However, the side effects disappeared after one year of clinical survey. The results indicate that gestrinone is effective in the treatment of pelvic endometriosis. In despite of a clear benefic effect on stage of the disease and symptoms; the use of gestrinone should weigh the risk-benefit (cost versus metabolic side effects) of treatment.

    In 2011, the Spanish Association of Pediatrics decided to support the most ambitious project of its newly created Committee for Medicinal Products: Pediamécum. This is the first free on-line database with information on medicinal products for pediatric use in Spain. The web page http://pediamecum.es/ started on December 17 December 2012. One year later, Pediamécum includes 580 registered drugs. The website achieved more than one million page views by the end of 2013. Because of the first anniversary of Pediamécum, a survey was performed to request the feeling of users. Four hundred eighty-three responses were obtained. Ninety-five percent believed that it is easy to navigate through the web, and 74% said that their doubts about the use of medicines in children were always resolved. The overall rating of Pediamécum is 7.5/10. The aims of Pediamécum are being accomplished; which is reflected essentially due to it becoming a useful tool for all professionals who care for children in their daily clinical practice.

    Results are presented on the activity carried out by our research group, in collaboration with the SME Optosmart s.r.l. (an Italian spin-off company), on the application of Fiber Optic Sensor (FOS) techniques to monitor high-energy physics (HEP) detectors. Assuming that Fiber Bragg Grating sensors (FBGs) radiation hardness has been deeply studied for other field of application, we have applied the FBG technology to the HEP research domain. We present here the experimental evidences of the solid possibility to use such a class of sensors also in HEP detector very complex environmental side conditions. In particular we present more than one year data results of FBG measurements in the Compact Muon Solenoid (CMS) experiment set up at the CERN, where we have monitored temperatures (within CMS core) and strains in different locations by using FBG sensors during the detector operation with the Large Hadron Collider (LHC) collisions and high magnetic field. FOS data and FOS readout system stability and reliability is demonstrated, with continuous 24/24 h 7/7d data taking under severe and complex side conditions.

    Full Text Available BINUS students are supposed to increase their English competence indicated by their TOEFL scores. This paper aims to observe the differences between studens TOEFL scores obtained when they entered BINUS and the scores after they joined TOEFL courses at BINUS for one year. The participants were 121 students. The data for the entrance test were taken from the BINUS data center and the final test data were taken from their final test at English class. The data were analysed using statistics especially the descriptive statistics, comparing means, and correlation. To support the quantative data, a set of questionnaires was distributed to those 121 students. The results show that the students’ TOEFL scores have increased significantly in the final test compared to those in the entrance test. The low achiever students showed a better performance than the higher ones. Students’ motivation and background support their English study. Students proved to have the most problem in listening. The results of the research are expected to be the input for English lecturers to improve their teaching especially the existence of SALLC (Self Access Language Learning Center.

    This paper experimentally investigates preference towards different methods of control in risk taking. Participants are asked to choose between different ways for choosing which numbers to bet on for a gamble. They can choose the numbers themselves (control), let the experimenter choose (no control), or randomize. It is found that in addition to the more conventional preference for control, some participants prefer not to control, or randomization. These preferences are robust as participants...

    The 2015 earthquake in Nepal killed over 8000 people, injured more than 21,000 and displaced a further 2 million. One year later, a national workshop was organized with various Nepali stakeholders involved in the response to the earthquake. The workshop provided participants an opportunity to reflect on their experiences and sought to learn lessons from the disaster. One hundred and thirty-five participants took part and most had been directly involved in the earthquake response. They included representatives from the Ministry of Health, local and national government, the armed forces, non-governmental organizations, health practitioners, academics, and community representatives. Participants were divided into seven focus groups based around the following topics: water, sanitation and hygiene, hospital services, health and nutrition, education, shelter, policy and community. Facilitated group discussions were conducted in Nepalese and the key emerging themes are presented. Participants described a range of issues encountered, some specific to their area of expertize but also more general issues. These included logistics and supply chain challenges, leadership and coordination difficulties, impacts of the media as well as cultural beliefs on population behaviour post-disaster. Lessons identified included the need for community involvement at all stages of disaster response and preparedness, as well as the development of local leadership capabilities and community resilience. A 'disconnect' between disaster management policy and responses was observed, which may result in ineffective, poorly planned disaster response. Finding time and opportunity to reflect on and identify lessons from disaster response can be difficult but are fundamental to improving future disaster preparedness. The Nepal Earthquake National Workshop offered participants the space to do this. It garnered an overwhelming sense of wanting to do things better, of the need for a Nepal-centric approach

    Acute poisonings are common and are treated at different levels of the health care system. Since most fatal poisonings occur outside hospital, these must be included when studying characteristics of such deaths. The pattern of toxic agents differs between fatal and non-fatal poisonings. By including all poisoning episodes, cause-fatality rates can be calculated. Fatal and non-fatal acute poisonings in subjects aged > or =16 years in Oslo (428 198 inhabitants) were included consecutively in an observational multi-centre study including the ambulance services, the Oslo Emergency Ward (outpatient clinic), and hospitals, as well as medico-legal autopsies from 1st April 2003 to 31st March 2004. Characteristics of fatal poisonings were examined, and a comparison of toxic agents was made between fatal and non-fatal acute poisoning. In Oslo, during the one-year period studied, 103 subjects aged > or =16 years died of acute poisoning. The annual mortality rate was 24 per 100 000. The male-female ratio was 2:1, and the mean age was 44 years (range 19-86 years). In 92 cases (89%), death occurred outside hospital. The main toxic agents were opiates or opioids (65% of cases), followed by ethanol (9%), tricyclic anti-depressants (TCAs) (4%), benzodiazepines (4%), and zopiclone (4%). Seventy-one (69%) were evaluated as accidental deaths and 32 (31%) as suicides. In 70% of all cases, and in 34% of suicides, the deceased was classified as drug or alcohol dependent. When compared with the 2981 non-fatal acute poisonings registered during the study period, the case fatality rate was 3% (95% C.I., 0.03-0.04). Methanol, TCAs, and antihistamines had the highest case fatality rates; 33% (95% C.I., 0.008-0.91), 14% (95% C.I., 0.04-0.33), and 10% (95% C.I., 0.02-0.27), respectively. Three per cent of all acute poisonings were fatal, and nine out of ten deaths by acute poisonings occurred outside hospital. Two-thirds were evaluated as accidental deaths. Although case fatality rates were

    Bilateral sacrospinous fixation with tailored mesh arms (bSSVF) uses polypropylene mesh to suspend the vault to the sacrospinous ligaments bilaterally with minimal tension, recreating nulliparous midline anatomy. It can be used with uterine conservation. Our primary objective was to determine objective cure rate at one year following bSSVF compared with a control group undergoing abdominal sacrocolpopexy (ASC). Secondary objectives were to compare symptoms, quality of life, sexual function, pain, and global satisfaction before and after surgery and between bSSVF and ASC groups at one year. This prospective cohort study enrolled patients with symptomatic prolapse who chose to undergo bSSVF or ASC. Baseline demographics were obtained. Prolapse quantification, validated symptom questionnaire scores, and McGill pain scores were obtained at baseline, six weeks, and one-year postoperatively. Global satisfaction was recorded. The primary outcome measure was the difference in cure rate (vault stage ≤ 1) between groups. Fifty patients were recruited: 30 underwent bSSVF and 17 ASC. Forty-three patients were available for one-year follow-up. Baseline data were similar. There was no difference in vault stage between bSSVF and ASC groups at one year. Five women who underwent bSSVF had cervical elongation, and four of these were classified as POP recurrence. Women who underwent bSSVF had more anterior recurrences but fewer postoperative complications, shorter hospital stay, and less use of narcotics than controls. Questionnaire scores were similar at one year. All respondents felt subjective improvement after either surgical procedure. Objective and subjective cure rates are comparable after bSSVF and ASC. Hysteropexy may cause cervical elongation that merits further research.

    Full Text Available A 51-year-old man came to our outpatient for one-year history of progressive myokymia in both legs. He had initially noted a “continuous muscle-fiber activity” of lower limbs in July 2013. Two months later, similar symptoms progressively affected muscles in both thighs and fundament, which was persistent during sleep. The frequency, duration and severity were gradually increased. He suffered from a feeling of tiredness and fatigue in both legs after long-time walking. In the local hospital, spinal MRI showed protrusion of C5-6, L4-5, L5-S1 intervertebral disc. One day in Oct 2013, his legs subsequently became generally stiff and painful to the point of a stiff paralysis and presented excessive sweating after drunk. This attack lasted for 30 min. Then he came to our clinic. Routine blood tests were normal. Electromyographic examination showed neurogenic damages of left thoracic paraspinal muscles. Abnormal F wave of left lower limb and discrete waveform of four limbs could be seen. Nerve conduction velocity (NCV and sympathetic skin response (SSR were unremarkable. Treatments with oral phenytoin sodium and carbamazepine were all ineffective. The attack occurred only a few times a year, especially after drunk, as well as the frequency, duration and severity roughly similar. He was admitted in our hospital in Oct 2014. The patient had a 9-year history of high blood pressure and the family history was normal. Neurological examination revealed generalized leg muscle hypertrophy, especially the gastrocnemius muscle, despite lack of physical exercise. Cranial nerves were intact. Hyperhidrosis was noted along with abundant myokymia that were evident in lower limbs. Muscle bulk and strength of upper limbs were normal. The deep tendon reflexes of lower limbs were unobtainable. Sensory and cerebellar examination revealed no dysfunction. Laboratory records showed that serum A type Sjögren's syndrome antibody (SSA and Ro52 antibody was positive

    The study tested the hypothesis that long-term soccer training has positive impact on cardiovascular profile, body composition, bone health, and physical capacity in inactive, pre-menopausal women with mild hypertension. The study applied a randomized controlled design in which physically inactive middle-aged women were separated into a soccer training group (n=19; SOC) and a control group (n=12; CON). SOC performed 128±29 (±SD) one-h small-sided soccer training sessions over one year. Blood pressure, body composition, blood lipid profile, and fitness level were determined pre- and post-intervention. Over one year, mean arterial pressure decreased more in SOC than in CON (-5±7 vs +4±5 mmHg; Pendurance level 1 (122±105 vs 2±21%) and 20-m sprint performance (6±6 vs -1±2%) increased more (Ptraining resulted in broad-spectrum improvements in the health profile of untrained, pre-menopausal women with mild hypertension, including cardiovascular, metabolic, and musculo-skeletal benefits. © 2017 John Wiley & Sons A/S.

    To report the 1-year treatment outcomes of the Ahmed Versus Baerveldt (AVB) Study. Multicenter randomized clinical trial. A total of 238 patients were enrolled in the study, including 124 in the Ahmed group and 114 in the Baerveldt group. Patients aged 18 years or older with uncontrolled glaucoma refractory to medicinal, laser, and surgical therapy were randomized to undergo implantation of an Ahmed-FP7 valve (New World Medical, Inc., Rancho Cucamonga, CA) or a Baerveldt-350 implant (Abbott Medical Optics, Inc., Santa Ana, CA), to be followed for 5 years. The primary outcome measure was failure, defined as intraocular pressure (IOP) out of target range (5-18 mmHg with ≥ 20% reduction from baseline) for 2 consecutive visits after 3 months, vision-threatening complications, additional glaucoma procedures, or loss of light perception. Secondary outcome measures included IOP, medication use, visual acuity, complications, and interventions. There were no significant differences in baseline ocular or demographic characteristics between the study groups with the exception of sex. Preoperatively, the study group had a mean IOP of 31.4 ± 10.8 mmHg on a mean of 3.1 ± 1.0 glaucoma medications with a median Snellen acuity of 20/100. The cumulative probability of failure a 1-year was 43% in the Ahmed group and 28% in the Baerveldt group (P = 0.02). The mean IOP at 1 year was 16.5 ± 5.3 mmHg in the Ahmed group and 13.6 ± 4.8 mmHg in the Baerveldt group (P glaucoma medications required was 1.6 ± 1.3 in the Ahmed group and 1.2 ± 1.3 in the Baerveldt group (P = 0.03). Visual acuity was similar in both groups at all visits in the first year (P = 0.66). In the first year after surgery, there were a similar number of patients who experienced postoperative complications in the 2 groups (45% Ahmed, 54% Baerveldt, P = 0.19), but a greater number of patients in the Baerveldt group required interventions (26% Ahmed vs. 42% Baerveldt, P = 0.009). The Baerveldt-350 group had a higher

    Full Text Available Abstract Background Several small, uncontrolled studies have found improvements in self-care behaviors and reductions in clinical risk in persons with type 2 diabetes who received care from licensed naturopathic physicians. To extend these findings and determine the feasibility and promise of a randomized clinical trial, we conducted a prospective study to measure the effects of adjunctive naturopathic care (ANC in primary care patients with inadequately controlled type 2 diabetes. Methods Forty patients with type 2 diabetes were invited from a large integrated health care system to receive up to eight ANC visits for up to one year. Participants were required to have hemoglobin A1c (HbA1c values between 7.5-9.5 % and at least one additional cardiovascular risk factor (i.e., hypertension, hyperlipidemia or overweight. Standardized instruments were administered by telephone to collect outcome data on self-care, self-efficacy, diabetes problem areas, perceived stress, motivation, and mood. Changes from baseline scores were calculated at 6- and 12-months after entry into the study. Six and 12-month changes in clinical risk factors (i.e., HbA1c, lipid and blood pressure were calculated for the ANC cohort, and compared to changes in a cohort of 329 eligible, non-participating patients constructed using electronic medical records data. Between-cohort comparisons were adjusted for age, gender, baseline HbA1c, and diabetes medications. Six months was pre-specified as the primary endpoint for outcome assessment. Results Participants made 3.9 ANC visits on average during the year, 78 % of which occurred within six months of entry into the study. At 6-months, significant improvements were found in most patient-reported measures, including glucose testing (P = 0.001, diet (P = 0.001, physical activity (P = 0.02, mood (P = 0.001, self-efficacy (P = 0.0001 and motivation to change lifestyle (P = 0.003.

    To evaluate the one-year prognosis of a lifestyle counselling intervention (diet, smoking cessation and exercise) among patients who had open heart surgery. Cardiovascular disease is the leading cause of morbidity worldwide in both developing and developed countries. Lifestyle modification plays an important role for patients who are at a high risk of developing cardiovascular disease and for those with an established cardiovascular disease. Randomised, nonblind and lifestyle counselling intervention study with a one-year follow-up. A randomised, nonblind intervention study was performed on 500 patients who had open heart surgery. After hospital discharge, 250 patients (intervention group) were randomly allocated lifestyle counselling according to the recent guidelines provided by the European Society of Cardiology (European Journal Preventive Cardiology, 19, 2012, 585). The remaining 250 patients (control group) received the regular instructions. Primary end-point was the development of a cardiovascular disease (nonfatal event) during the first year; secondary end-points included fatal events, smoking abstinence, dietary habits and a physical activity evaluation. According to the primary end-point, the odds of having a nonfatal cardiovascular disease event are 0·56-times (95%CI 0·28, 0·96, p = 0·03) lower for the intervention group compared to the control group. One-year after surgery, it was found that participants in the intervention group were 1·96-times (95%CI 1·31, 2·93, p open heart surgery can improve health outcomes and reduce the risk of a new cardiac event. Health care services must recommend and organise well-structured cardiac rehabilitation programmes adjusted to the patient's needs. A well-structured cardiac rehabilitation programme adjusted to the patient's profile is a safe and cost-effective way to improve patients' outcome. © 2015 John Wiley & Sons Ltd.

  6. EDITORIAL: Celebrating one year of Environmental Research Letters

    Kammen, Daniel M.

    2008-03-01

    The one-year anniversary is a critical milestone for a new journal. At that point there are enough articles published to begin to define the scope and readership, yet generally not enough of a track-record for the full community to regard the new entrant as a fixture and a source of 'must read' material. Environmental Research Letters (ERL) has set itself a particularly large and interesting challenge: to help connect the vast community of environmental researchers, practitioners, activists, and interested informed observers. ERL and its partner online resource base and community website, environmentalresearchweb, fills a major void: a single locus for rapid publication of peer-reviewed and highly interdisciplinary material spanning literally every aspect of environmental research and thought. The wide range of material that falls squarely into the purview of ERL—from restoration ecology to global change science and politics, to toxicology and environmental justice, to environmental and social impacts of energy conversion—illustrate just how diverse a 'community' we hope to serve. Thanks to an exceptional editorial staff and board, and a diverse range of fascinating contributed papers, ERL is off to a particularly fast start. ERL has both a small advisory board and a larger editorial board. The board serves several functions, beginning with the traditional one of taking the lead on reviews of papers in such a dizzying array of areas. This task alone is a challenge because of the commitment ERL has made to exceptionally rapid publication: a goal of 90 days from submission to online publication for accepted papers. This goal, which we have generally met, includes the publication of complementary (but not always complimentary) 500 1000 word commentaries on a number of papers. To accomplish this alone the editorial board, and the reviewers, have been heroic, and deserve a huge round of applause. IOP Publishing too, has been truly wonderful in making this happen

    Native warm season grasses, big bluestem and indian, were established by the broadcast method on a relatively large area (130 acres) of reclaimed coal surface-mined land in Perry County, Illinois. Existing vegetation was controlled using two quarts of Round-Up and 12 ounces of Plateau per acre the first week of May. Five pounds of pure live seed of both species were applied by airflow using 100 pounds per acre of 0-46-0 and 100 pounds per acre of 0-0-60, primarily to carry the seed. The surface was cultipacked to insure good seed to soil contact. Planting was initiated and completed the last week of June. An estimated 95% to 100% ground cover was evident by mid to late August. By mid September, numerous big blue stem flower/seed stalks were noticeable

    Purpose To determine the relative efficacy and complications of the Ahmed FP7 Glaucoma Valve (AGV) and the Baerveldt 101–350 Glaucoma Implant (BGI) in refractory glaucoma. Design Multicenter randomized controlled clinical trial. Participants 276 patients, including 143 in the AGV group and 133 in the BGI group. Methods Patients aged 18–85 years with refractory glaucoma with intraocular pressure (IOP) greater than or equal to 18 mm Hg in whom an aqueous shunt was planned were randomized to undergo implantation of either an AGV or a BGI. Main Outcome Measures Primary outcome was failure, defined as IOP > 21 mm Hg or not reduced by 20%, IOP ≤ 5 mm Hg, reoperation for glaucoma or removal of implant, or loss of light perception vision. Secondary outcomes included mean IOP, visual acuity, use of supplemental medical therapy, and complications. Results Preoperative IOP (mean ± standard deviation, SD) was 31.2 ± 11.2 in the AGV group and 31.8 ± 12.5 in the BGI group (p = 0.71). At 1 year, IOP was 15.4 ± 5.5 mm Hg in the AGV group and 13.2 ± 6.8 mm Hg in the BGI group (p = 0.007). The number of glaucoma medications (mean ± SD) was 1.8 ± 1.3 in the AGV group and 1.5 ± 1.4 in the BGI group (p = 0.071). The cumulative probability of failure was 16.4% (standard error, SE = 3.1%) in the AGV group and 14.0% (SE = 3.1%) in the BGI group at 1 year (p = 0.52). More patients experienced early postoperative complications in the BGI group (n = 77, 58%) compared to the AGV group (n = 61, 43%, p = 0.016). Serious postoperative complications associated with reoperation and/or vision loss of ≥ 2 Snellen lines occurred in 29 patients (20%) in the AGV group and 45 patients (34%) in the BGI group (p = 0.014). Conclusions Although the average IOP after one year was slightly higher in patients who received an AGV, there were fewer early and serious postoperative complications associated with the use of the AGV than the BGI.

    It is necessary to place number of sensors at different positions in sound field to determine actual sound intensities to which test object is subjected. It is possible to determine whether specification is being met adequately or exceeded. Since excitation is of random nature, signals are essentially coherent and it is impossible to obtain true average.

    We examined how personality strengths prospectively predict reactions to negative life events. Participants were 797 community adults from 42 countries. At five points over the course of 1 year, participants completed a series of questionnaires measuring seven personality strengths (hope, grit, meaning in life, curiosity, gratitude, control beliefs, and use of strengths), subjective well-being, and frequency and severity of negative life events. Using hierarchical linear modeling with assessment periods nested within participants, results from lagged analyses found that only hope emerged as a resilience factor. To illustrate the importance of using appropriate lagged analyses in resilience research, we ran nonlagged analyses; these results suggest that all seven personality strengths moderated the effect of negative life events on subjective well-being, with greater strengths associated with healthier outcomes. To provide evidence that personality strengths confer resilience, a prospective examination is needed with the inclusion of events and responses to them. The use of concurrent methodologies and analyses, which is the norm in psychology, often leads to erroneous conclusions. Hope, the ability to generate routes to reach goals and the motivation to use those routes, was shown to be particularly important in promoting resilience. © 2016 Wiley Periodicals, Inc.

  11. RTE: a first assessment after one year of existence

    International Nuclear Information System (INIS)

    Merlin, A.

    2001-01-01

    Just over a year ago, on 1 July 2000, the manager of the French public Electricity Transport Network - RTE - entered the French electricity scene. Its creation is a result of the law of 10 February 2000 concerning the modernization and development of the electric utility, which transposes into French Law the European directive of December 1996. This law, which organizes the introduction in the market French electricity scene, foresees that the transport network manager is independent from EDF's other activities, for this network can now be used not solely by the famous operator. The entire equipment and most of the skills which contribute to the management of the public transport network were thus separated from EDF's other activities and merged into what has become RTE. This separation has been carefully prepared as soon as the principles of introduction of competition in the electricity market were established by the European directive. It was created in six month with the help of the regulatory and control authorities, the Secretary of State for Industry and the Electricity Regulation Committee (CRE). This anticipation has enabled a smooth transition and if RTE remains with EDF,it is today completely independent for managerial, accounting and financial aspects. (author)

    Infectious livestock diseases remain a major threat to attaining food security and are a source of economic and livelihood losses for people dependent on livestock for their livelihood. Knowledge of the vital infectious diseases that account for the majority of deaths is crucial in determining disease control strategies and in the allocation of limited funds available for disease control. Here we have estimated the mortality rates in zebu cattle raised in a smallholder mixed farming system during their first year of life, identified the periods of increased risk of death and the risk factors for calf mortality, and through analysis of post-mortem data, determined the aetiologies of calf mortality in this population. A longitudinal cohort study of 548 zebu cattle was conducted between 2007 and 2010. Each calf was followed during its first year of life or until lost from the study. Calves were randomly selected from 20 sub-locations and recruited within a week of birth from different farms over a 45 km radius area centered on Busia in the Western part of Kenya. The data comprised of 481.1 calf years of observation. Clinical examinations, sample collection and analysis were carried out at 5 week intervals, from birth until one year old. Cox proportional hazard models with frailty terms were used for the statistical analysis of risk factors. A standardized post-mortem examination was conducted on all animals that died during the study and appropriate samples collected. The all-cause mortality rate was estimated at 16.1 (13.0-19.2; 95% CI) per 100 calf years at risk. The Cox models identified high infection intensity with Theileria spp., the most lethal of which causes East Coast Fever disease, infection with Trypanosome spp., and helminth infections as measured by Strongyle spp. eggs per gram of faeces as the three important infections statistically associated with infectious disease mortality in these calves. Analysis of post-mortem data identified East Coast Fever as

    pressure sores and the parameters relating to nutritional status (albumin, cholesterol, body weight and total lymphocyte count) except for the level of hemoglobin. Since there was no control group, the results of the study, naturally, did not show any advantage in treatment of pressure sores in a specific unit as opposed to such treatment in a general ward. Nevertheless, the need for a Pressure Sores Unit is justified and important. It is possible that the patients observed in this study arrived for treatment in the unit at very late, irreversible and terminal stages. The presence of a Pressure Sores Unit would heighten awareness and early referral of these patients.

    The role of the stimulus-reinforcer contingency in the development and maintenance of lever contact responding was studied in hooded rats. In Experiment I, three groups of experimentally naive rats were trained either on autoshaping, omission training, or a random-control procedure. Subjects trained by the autoshaping procedure responded more consistently than did either random-control or omission-trained subjects. The probability of at least one lever contact per trial was slightly higher in subjects trained by the omission procedure than by the random-control procedure. However, these differences were not maintained during extended training, nor were they evident in total lever-contact frequencies. When omission and random-control subjects were switched to the autoshaping condition, lever contacts increased in all animals, but a pronounced retardation was observed in omission subjects relative to the random-control subjects. In addition, subjects originally exposed to the random-control procedure, and later switched to autoshaping, acquired more rapidly than naive subjects that were exposed only on the autoshaping procedure. In Experiment II, subjects originally trained by an autoshaping procedure were exposed either to an omission, a random-control, or an extinction procedure. No differences were observed among the groups either in the rate at which lever contacts decreased or in the frequency of lever contacts at the end of training. These data implicate prior experience in the interpretation of omission-training effects and suggest limitations in the influence of stimulus-reinforcer relations in autoshaping.

    Full Text Available Abstract Background The literature on changes in health-related quality of life (HRQOL in weight loss studies is inconsistent, and few studies use more than one type of measure. The purpose of the current study was to compare one-year changes in HRQOL as a function of weight change using three different measures: a weight-related measure (Impact of Weight on Quality of Life-Lite [IWQOL-Lite] and two generic measures (SF-36; EQ-5D. Methods Data were obtained from 926 participants (mean Body Mass Index (BMI (kg/m2 = 35.4; 84% female; mean age = 49.5 years in a placebo-controlled randomized trial for weight loss. At baseline and one-year, participants completed all three HRQOL measures. HRQOL was compared across weight change categories (≥ 5% and 0–4.9% gain, 0–4.9%, 5.0–9.9% and ≥ 10% loss, using effect sizes. Results The weight-related measure of HRQOL exhibited greater improvements with one-year weight loss than either of the generic instruments, with effect sizes ranging from 0.24 to 0.62 for 5–9.9% weight reductions and 0.44 to 0.95 for ≥ 10% reductions. IWQOL-Lite Self-Esteem also showed a small improvement with weight gain. Changes in the two generic measures of HRQOL were inconsistent with each other, and in the case of the SF-36, variable across domains. For participants gaining ≥ 5% of weight, the greatest reductions in HRQOL occurred with respect to SF-36 Mental Health, MCS, and Vitality, with effect sizes of -0.82, -0.70, and -0.63 respectively. Conclusion This study found differences between weight-related and generic measures of health-related quality of life in a one-year weight loss trial, reflecting the potential value of using more than one measure in a trial. Although weight loss was generally associated with improved IWQOL-Lite, physical SF-36 subscale and EQ-5D scores, a small amount of weight gain was associated with a slight improvement on weight-specific HRQOL and almost no change on the EQ-5D, suggesting the

    Full Text Available Abstract Background Currently the American Red Cross requires that individuals renew their cardiopulmonary resuscitation (CPR certification annually; this often requires a 4- to 8-hour refresher course. Those trained in CPR often show a decrease in essential knowledge and skills within just a few months after training. New electronic means of communication have expanded the possibilities for delivering CPR refreshers to members of the general public who receive CPR training. The study’s purpose was to determine the efficacy of three novel CPR refreshers - online website, e-mail and text messaging – for improving three outcomes of CPR training - skill retention, confidence for using CPR and intention to use CPR. These three refreshers may be considered “novel” in that they are not typically used to refresh CPR knowledge and skills. Methods The study conducted two randomized clinical trials of the novel CPR refreshers. A mailed brochure was a traditional, passive refresher format and served as the control condition. In Trial 1, the refreshers were delivered in a single episode at 6 months after initial CPR training. In Trial 2, the refreshers were delivered twice, at 6 and 9 months after initial CPR training, to test the effect of a repeated delivery. Outcomes for the three novel refreshers vs. the mailed brochure were determined at 12 months after initial CPR training. Results Assignment to any of three novel refreshers did not improve outcomes of CPR training one year later in comparison with receiving a mailed brochure.

Os fatores de risco investigados foram variáveis relacionadas à história gestacional da mãe e ao nascimento da criança, às condições sociais da família e à utilização de serviços de saúde. Na primeira etapa de análise, através de um modelo de regressão logística univariada, foram estimados os coeficientes de cada variável independente, o risco relativo e seus limites de confiança. O peso ao nascer e a idade do desmame mostraram-se das mais fortemente associadas com a variável dependente. Na segunda etapa, foi feito o ajuste pelo modelo de regressão logística múltipla e somente 4 variáveis permaneceram estatisticamente associadas com a mortalidade: idade do desmame, peso ao nascer, número de moradores da casa e aplicação da vacina BCG. Conclui-se que a mortalidade por pneumonia em menores de um ano está fortemente associada às condições sociais da família, em particular da mãe.In a case-control study, a sample of post-neonatal deaths from pneumonia occurring in the Metropolitan Area of Rio de Janeiro, Brazil (1986-1987 were compared with healthy controls who lived in the same neighborhood.

    In the fields of data mining and control, the huge amount of unstructured data and the presence of uncertainty in system descriptions have always been critical issues. The book Randomized Algorithms in Automatic Control and Data Mining introduces the readers to the fundamentals of randomized algorithm applications in data mining (especially clustering) and in automatic control synthesis. The methods proposed in this book guarantee that the computational complexity of classical algorithms and the conservativeness of standard robust control techniques will be reduced. It is shown that when a problem requires "brute force" in selecting among options, algorithms based on random selection of alternatives offer good results with certain probability for a restricted time and significantly reduce the volume of operations.

    The subcortical deep gray matter (DGM) develops selective, progressive, and clinically relevant atrophy in progressive forms of multiple sclerosis (PMS). This patient population is the target of active neurotherapeutic development, requiring the availability of outcome measures. We tested a fully automated MRI analysis pipeline to assess DGM atrophy in PMS. Consistent 3D T1-weighted high-resolution 3T brain MRI was obtained over one year in 19 consecutive patients with PMS [15 secondary progressive, 4 primary progressive, 53% women, age (mean±SD) 50.8±8.0 years, Expanded Disability Status Scale (median, range) 5.0, 2.0-6.5)]. DGM segmentation applied the fully automated FSL-FIRST pipeline ( http://fsl.fmrib.ox.ac.uk ). Total DGM volume was the sum of the caudate, putamen, globus pallidus, and thalamus. On-study change was calculated using a random-effects linear regression model. We detected one-year decreases in raw [mean (95% confidence interval): -0.749 ml (-1.455, -0.043), p = 0.039] and annualized [-0.754 ml/year (-1.492, -0.016), p = 0.046] total DGM volumes. A treatment trial for an intervention that would show a 50% reduction in DGM brain atrophy would require a sample size of 123 patients for a single-arm study (one-year run-in followed by one-year on-treatment). For a two-arm placebo-controlled one-year study, 242 patients would be required per arm. The use of DGM fraction required more patients. The thalamus, putamen, and globus pallidus, showed smaller effect sizes in their on-study changes than the total DGM; however, for the caudate, the effect sizes were somewhat larger. DGM atrophy may prove efficient as a short-term outcome for proof-of-concept neurotherapeutic trials in PMS.

    BACKGROUND: Despite intensive insulin treatment, many patients with type-1 diabetes (T1DM) have longstanding inadequate glycaemic control. Metformin is an oral hypoglycaemic agent that improves insulin action in patients with type-2 diabetes. We investigated the effect of a one-year treatment...... with metformin versus placebo in patients with T1DM and persistent poor glycaemic control. METHODOLOGY/PRINCIPAL FINDINGS: One hundred patients with T1DM, preserved hypoglycaemic awareness and HaemoglobinA(1c) (HbA(1c)) > or = 8.5% during the year before enrolment entered a one-month run-in on placebo treatment....... Thereafter, patients were randomized (baseline) to treatment with either metformin (1 g twice daily) or placebo for 12 months (double-masked). Patients continued ongoing insulin therapy and their usual outpatient clinical care. The primary outcome measure was change in HbA(1c) after one year of treatment...

    The Academy for Future Science Faculty (the Academy) is a novel coaching intervention for biomedical PhD students designed to address limitations in previous efforts to promote faculty diversity. Unlike traditional research mentoring, the Academy includes both group and individual coaching, coaches have no research or evaluation roles with the students, and it is based on social science theories. The authors present a qualitative case study of one of the coaching groups and provide statistical analyses indicating whether one year in the Academy effects students' perceptions of the achievability and desirability of an academic career. The authors tested (July 2012-July 2013), with Northwestern University ethical approval, the Academy via a longitudinal randomized controlled trial. Participants were 121 latter-stage biomedical PhD students. The authors collected data via questionnaires, interviews, and meeting recordings. The case study shows how group career coaching can effectively supplement traditional one-to-one research mentoring; provide new role models for underrepresented minority students; and provide theory-based lenses through which to engage in open conversations about race, gender, and science careers. Repeated-measures analysis of variance showed that perceived achievability increased in the Academy group from baseline to one-year follow-up (mean, 5.75 versus 6.39) but decreased in the control group (6.58 versus 5.81). Perceived desirability decreased significantly less (P coaching model can effectively supplement traditional research mentoring and promote persistence toward academic careers.

    Comparison of the effects of one year treatment with sibutramine compared to placebo on insulin resistance parameters, body weight, glycemic control, and lipid profile, in type 2 diabetic patients. Two hundred and forty-six patients with uncontrolled type 2 diabetes mellitus in therapy with different oral hypoglycemic agents or insulin were enrolled in this study and randomised to take sibutramine 10 mg or placebo for one year. We evaluated at baseline, and after 3, 6, 9, and 12 months these parameters: homeostasis model assessment insulin resistance index (HOMA-IR), retinol binding protein-4 (RBP-4), resistin, visfatin, and high sensitivity-C reactive protein (Hs-CRP), body weight, body mass index (BMI), glycated hemoglobin (HbA(₁c)), fasting plasma glucose (FPG), post-prandial plasma glucose (PPG), fasting plasma insulin (FPI), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C), and triglycerides (T(g)). A faster decrease of HOMA-IR, resistin, and RBP-4 was recorded with sibutramine compared to the control group. We observed a significant decrease of Hs-CRP in both groups, and a faster improvement of HbA(₁c), FPG and PPG with sibutramine compared to the control group; furthermore we recorded a decrease of FPI, TC, LDL-C, body weight, and BMI in the sibutramine group, but not in the control group. Sibutramine gave a faster improvement of insulin resistance parameters and glycemic control compared to placebo; furthermore sibutramine gave also an improvement of lipid profile, and body weight.

    A pilot study assessed an electronic informed consent model within a randomized controlled trial (RCT). Participants who were recruited for the parent RCT project were randomly selected and randomized to either an electronic consent group (n = 32) or a simplified paper-based consent group (n = 30). Results from the electronic consent group reported significantly higher understanding of the purpose of the study, alternatives to participation, and who to contact if they had questions or concerns about the study. However, participants in the paper-based control group reported higher mean scores on some survey items. This research suggests that an electronic informed consent presentation may improve participant understanding for some aspects of a research study. © The Author(s) 2014.

    Full Text Available Disease-related worries are frequently reported in inflammatory bowel disease (IBD, but longitudinal assessments of these worries are scarce. In the present study, patients completed the rating form of IBD patient concerns (RFIPC at three occasions during one year. One-way analysis of variance (ANO VA, t-tests, bivariate correlation, and linear regression analyses were used to analyse data. The validity and reliability of the Norwegian RFIPC was tested. A total of 140 patients were included (V1, ulcerative colitis (UC n = 92, Crohn's disease (CD n = 48, mean age 46.9 and 40.0-year old, respectively. The highest rated worries included having an ostomy bag, loss of bowel control, and reduced energy levels. Symptoms were positively associated with more worries. A pattern of IBD-related worries was consistent over a period of one year. Worries about undergoing surgery or having an ostomy bag seemed to persist even when symptoms improved. The Norwegian RFIPC is valid and reliable.

    Full Text Available Abstract Background Insulin resistance (IR is the major driving force behind development and progression of atherosclerosis in patients with nonalcoholic fatty liver disease (NAFLD. Therefore, correction of IR is a relevant therapeutic target. We performed the current trial to evaluate whether 12- month metformin therapy improves vascular stiffness in patients with NAFLD and to assess if this improvement is associated with change in glucose control, insulin resistance or circulating adiponectin. Methods In randomized, placebo controlled study, 63 patients with NAFLD were assigned to one of two groups: Group 1 received daily metformin; Group 2 received placebo. Central aortic augmentation index (AI was performed using SphygmoCor (version 7.1, AtCor Medical, Sydney, Australia at baseline, at 4-and 12-month treatment period. Metabolic parameters, insulin resistance markers and serum adiponectin levels were determined. Results In placebo group: AI did not improve during the treatment period. Liver function and adiponectin levels did not change during the study. In multiple linear regression analysis, the independent predictors of arterial stiffness improvement were metformin treatment and increase in circulating adiponectin levels. Among metformin treated patients: AI decreased significantly during the study. ALP and ALT decreased during initial 4-month treatment period, however raised to the pretreatment levels after 12 months. Serum adiponectin level tended to increase during treatment period with metformin. Conclusions Metformin treatment was associated with significant decrease in AI during one year treatment in NAFLD patients. These beneficial vascular effects was associated with exposure to metformin per se as well as change in adiponectin levels suggesting that metformin may mediate its vascular effects via glicemic control-independent mechanisms.

    A randomized, controlled fall-prevention study including 199 patients operated on for femoral neck fracture reduced inpatient falls and injuries. No statistically significant effects of the intervention program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone old people. This study evaluates whether a postoperative multidisciplinary, multifactorial fall-prevention program performed by a geriatric team that reduced inpatient falls and injuries had any continuing effect after discharge. The intervention consisted of staff education, systematic assessment and treatment of fall risk factors and vitamin D and calcium supplementation. The randomized, controlled trial with a one-year follow-up at Umeå University Hospital, Sweden, included 199 patients operated on for femoral neck fracture, aged > or = 70 years. After one year 44 participants had fallen 138 times in the intervention group compared with 55 participants and 191 falls in the control group. The crude postoperative fall incidence was 4.16/1,000 days in the intervention group vs. 6.43/1,000 days in the control group. The incidence rate ratio was 0.64 (95% CI: 0.40-1.02, p = 0.063). Seven new fractures occurred in the intervention group and 11 in the control group. A team applying comprehensive geriatric assessment and rehabilitation, including prevention and treatment of fall-risk factors, reduced inpatient falls and injuries, but no statistically significant effects of the program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone elderly.

    Surgical site infections are the most common hospital-acquired infections among surgical patients. The administration of surgical antimicrobial prophylaxis reduces the risk of surgical site infections . The optimal timing of this procedure is still a matter of debate. While most studies suggest that it should be given as close to the incision time as possible, others conclude that this may be too late for optimal prevention of surgical site infections. A large observational study suggests that surgical antimicrobial prophylaxis should be administered 74 to 30 minutes before surgery. The aim of this article is to report the design and protocol of a randomized controlled trial investigating the optimal timing of surgical antimicrobial prophylaxis. In this bi-center randomized controlled trial conducted at two tertiary referral centers in Switzerland, we plan to include 5,000 patients undergoing general, oncologic, vascular and orthopedic trauma procedures. Patients are randomized in a 1:1 ratio into two groups: one receiving surgical antimicrobial prophylaxis in the anesthesia room (75 to 30 minutes before incision) and the other receiving surgical antimicrobial prophylaxis in the operating room (less than 30 minutes before incision). We expect a significantly lower rate of surgical site infections with surgical antimicrobial prophylaxis administered more than 30 minutes before the scheduled incision. The primary outcome is the occurrence of surgical site infections during a 30-day follow-up period (one year with an implant in place). When assuming a 5% surgical site infection risk with administration of surgical antimicrobial prophylaxis in the operating room, the planned sample size has an 80% power to detect a relative risk reduction for surgical site infections of 33% when administering surgical antimicrobial prophylaxis in the anesthesia room (with a two-sided type I error of 5%). We expect the study to be completed within three years. The results of this

    The links between social capital and mental wellbeing are established but the direction of the social capital-wellbeing relationship is rarely systematically examined. This omission undermines the validity of social capital as a basis for health interventions. The aim of this paper was to explore the short-term (one-year) reciprocal relationship between community participation - an important component of social capital - and mental wellbeing. We used nationally representative Household, Income and Labour Dynamics in Australia (HILDA) Survey data, 2005-11. The HILDA Survey is an annual cohort study from which was extracted a sub-sample of panel data (the same people participating across multiple waves) enabling us to use fixed effects regression methods to model the longitudinal association of mental health and participation controlling for individual heterogeneity. The results showed that better mental wellbeing in one year was generally related to more community participation the next year, while greater past community participation was linked to better mental wellbeing the next year independent of (i) initial mental wellbeing, (ii) multiple potentially confounding factors and (iii) unobserved and time-constant heterogeneity. Political participation was marginally related to worse mental health in both directions. The results also showed that the association between community participation and mental wellbeing the next year is weaker for those with poor initial wellbeing than for initially healthier respondents. Our findings may inform the trial and scientific evaluation of programs aimed at increasing informal social connectedness and civic engagement to promote mental wellbeing.

    Background To compare one-year all-cause and uterine fibroid (UF)-related direct costs in patients treated with one of the following three uterine-sparing procedures: magnetic resonance-guided focused ultrasound (MRgFUS), uterine artery embolization (UAE) and myomectomy. Methods This retrospective observational cohort study used healthcare claims for several million individuals with healthcare coverage from employers in the MarketScan Database for the period 2003–2010. UF patients aged 25–54 on their first UF procedure (index) date with 366-day baseline experience, 366-day follow-up period, continuous health plan enrollment during baseline and follow-up, and absence of any baseline UF procedures were included in the final sample. Cost outcomes were measured by allowed charges (sum of insurer-paid and patient-paid amounts). UF-related cost was defined as difference in mean cost between study cohorts and propensity-score-matched control cohorts without UF. Multivariate adjustment of cost outcomes was conducted using generalized linear models. Results The study sample comprised 14,426 patients (MRgFUS = 14; UAE = 4,092; myomectomy = 10,320) with a higher percent of older patients in MRgFUS cohort (71% vs. 50% vs. 12% in age-group 45–54, P UAE ($25,019; 95% CI: $23,738-$26,376) but without statistical significance. Adjusted UF-related costs were also not significantly different between the three procedures. Conclusions Adjusted all-cause and UF-related costs at one year were not significantly different between patients undergoing MRgFUS, myomectomy and UAE. PMID:25512868

    Identification and elimination of non-meteorological radar echoes (e.g., returns from ground, wind turbines, and biological targets) are the basic data quality control steps before radar data use in quantitative applications (e.g., precipitation estimation). Although WSR-88Ds' recent upgrade to dual-polarization has enhanced this quality control and echo classification, there are still challenges to detect some non-meteorological echoes that show precipitation-like characteristics (e.g., wind turbine or anomalous propagation clutter embedded in rain). With this in mind, a new quality control method using Random Forest is proposed in this study. This classification algorithm is known to produce reliable results with less uncertainty. The method introduces randomness into sampling and feature selections and integrates consequent multiple decision trees. The multidimensional structure of the trees can characterize the statistical interactions of involved multiple features in complex situations. The authors explore the performance of Random Forest method for NEXRAD radar data quality control. Training datasets are selected using several clear cases of precipitation and non-precipitation (but with some non-meteorological echoes). The model is structured using available candidate features (from the NEXRAD data) such as horizontal reflectivity, differential reflectivity, differential phase shift, copolar correlation coefficient, and their horizontal textures (e.g., local standard deviation). The influence of each feature on classification results are quantified by variable importance measures that are automatically estimated by the Random Forest algorithm. Therefore, the number and types of features in the final forest can be examined based on the classification accuracy. The authors demonstrate the capability of the proposed approach using several cases ranging from distinct to complex rain/no-rain events and compare the performance with the existing algorithms (e

    Cognitive dysfunction and histological changes in the brain were investigated following irradiation in 20 Fischer 344 rats aged 6 months treated with whole brain irradiation (WBR) (25 Gy/single dose), and compared with the same number of sham-irradiated rats as controls. Performance of the Morris water maze task and the passive avoidance task were examined one year after WBR. Finally, histological and immunohistochemical examinations using antibodies to myelin basic protein (MBP), glial fibrillary acidic protein (GFAP), and neurofilament (NF) were performed of the rat brains. The irradiated rats continued to gain weight 7 months after WBR whereas the control rats stopped gaining weight. Cognitive functions in both the water maze task and the passive avoidance task were lower in the irradiated rats than in the control rats. Brain damage consisting of demyelination only or with necrosis was found mainly in the body of the corpus callosum and the parietal white matter near the corpus callosum in the irradiated rats. Immunohistochemical examination of the brains without necrosis found MBP-positive fibers were markedly decreased in the affected areas by irradiation; NF-positive fibers were moderately decreased and irregularly dispersed in various shapes in the affected areas; and GFAP-positive fibers were increased, with gliosis in those areas. These findings are similar to those in clinically accelerated brain aging in conditions such as Alzheimer's disease, Binswanger's disease, and multiple sclerosis. (author)

    Full Text Available Introduction: Attention-deficit/hyperactivity disorder (ADHD is a common comorbid disorder in patients suffering from substance use disorder (SUD. Individuals with co-occurring SUD and ADHD are more likely than SUD patients without ADHD to have developed SUD at a younger age, be polysubstance users, and need inpatient treatment more often. The present study investigates whether individuals with polysubstance use disorder who remain abstinent for a year after entering treatment have a more substantial reduction in ADHD symptoms than those who relapsed and controls. Material and methods: Subjects were SUD patients (N=115 and healthy controls (N=34. ADHD symptoms were assessed using the adult ADHD Self-Report Scale (ASRS. Substance use was assessed by self-reports on the Alcohol Use Disorders Identification Test (AUDIT and the Drug Use Disorders Identification Test (DUDIT. Participants were defined as having relapsed if they had an AUDIT score≥8 or a DUDIT score≥2 for women and≥6 for men. Results: Patients who remained abstinent for one year reported a substantial reduction of ADHD symptoms compared to patients who relapsed and controls. Conclusions: Abstinence alleviates ADHD symptoms among patients with polysubstance use disorder. We suggest that confirmation of an ADHD diagnosis should follow a period of abstinence to avoid identification of false-positive cases.

    To evaluate the effectiveness of an MRI-specific play therapy intervention on the need for sedation in young children. All children in the age group of 4-10 y, who were advised an MRI scan over a period of one year were randomized. Exclusion criteria included children with neurodevelopmental disorders impairing cognition and children who had previously undergone diagnostic MRI. A total of 79 children were randomized to a control or an intervention condition. The intervention involved familiarizing the child with the MRI model machine, listing the steps involved in the scan to the child in vivid detail, training the child to stand still for 5 min, and conducting several dry runs with a doll or a favorite toy. The study was approved by the Institute ethical committee. The need for sedation was 41 % (n = 16) in the control group and this declined to 20 % (n = 8) in the intervention group (χ(2) = 4.13; P = 0.04). The relative risk of sedation decreased by 49 % in the intervention group as compared to the control group (RR 0.49; 95 % CI: 0.24-1.01) and this difference was statistically significant (P = 0.04). The absolute risk difference in sedation use between intervention and control group was 21 % (95 % CI 1.3 %-40.8 %). Even on adjusting for age, relative risk of sedation remained significantly lower in children undergoing play therapy as compared to the control (RR 0.57, 95 % CI: 0.32-0.98) with P value of 0.04. The use of an MRI customized play therapy with pediatric patients undergoing diagnostic MRI resulted in significant reduction of the use of sedation.

    Pancreatic cancer is often accompanied by severe abdominal or back pain. It's the first study to evaluate the analgesic effect of electroacupuncture on pancreatic cancer pain. A randomized controlled trial compared electroacupuncture with control acupuncture using the placebo needle. Sixty patients with pancreatic cancer pain were randomly assigned to the electroacupuncture group (n = 30) and the placebo control group (n = 30). Patients were treated on Jiaji (Ex-B2) points T8-T12 bilaterally for 30 min once a day for 3 days. Pain intensity was assessed with numerical rated scales (NRS) before the treatment (Baseline), after 3 treatments, and 2 days follow-up. Baseline characteristics were similar in the two groups. After 3 treatment, pain intensity on NRS decreased compared with Baseline (-1.67, 95% confidence interval [CI] -1.46 to -1.87) in the electroacupuncture group; there was little change (-0.13, 95% CI 0.08 to -0.35) in control group; the difference between two groups was statistically significant (P electroacupuncture group compared with the control group (P Electroacupuncture was an effective treatment for relieving pancreatic cancer pain.

    A randomized, double-blind, controlled clinical trial was conducted to evaluate the effectiveness of a propolis rinse on induced gingivitis by using the co-twin study design. Twenty-one twin pairs (n=42) were enrolled in a gingivitis study with oral hygiene promotion (14 days) and gingivitis induction (21 days). During the gingivitis induction phase, one member of the twin pair was randomly assigned to a 2% typified propolis rinse, and the other was assigned a color-matched 0.05% sodium fluoride plus 0.05% cetylpyridinium chloride rinse (positive control). Patients rinsed twice daily with 20 mL for 30 seconds for 21 days. Gingivitis was measured on days -14 (baseline), 0 (after hygiene phase), and 21 (after no-hygiene phase) by using the Papillary Bleeding Score (PBS) and by standard digital imaging of the gum tissues (G-parameter). The 38 persons who completed the study (age 13-22 years) were well balanced according to PBS at baseline and G-parameter after the initial hygiene phase. After 21 days without oral hygiene, the propolis rinse and positive control rinse groups did not differ significantly for average PBS measurements or G-parameter. Use of a 2% typified propolis rinse was equivalent to a positive control rinse during a 21-day no-hygiene period.

    One year after launching Areva's Action 2016 strategic plan, the first results are in. AREVA is ahead of schedule in executing its recovery plan. While pursuing its efforts in the management of a few difficult projects (such as OL3), Areva group was able to return to a virtuous performance cycle rooted in strong growth in nuclear order intake and good progress on its cost reduction program. Commercially, despite the difficult economic environment, AREVA was able to capitalize on its leadership in the installed base and on its long-term partnerships with strategic customers, beginning with EDF, with which AREVA renewed a confident and constructive working relationship. Areva has secured 80% of its objective of one billion euros of savings by the end of 2015 to improve its competitiveness. The group also continued efforts to optimize working capital requirement and control the capital expenditure trajectory. Together, these results enabled AREVA to exceed the objectives set for 2012 for two key indicators of its strategic plan: EBITDA and free operating cash flow. Nearly 60% of the 2.1 billion euros devoted to capital expenditures for future growth in 2012 were funded by operations, a quasi-doubled share compared to 2011. Areva's floor target for asset disposals was achieved one year ahead of schedule, also helping the Group to control its net debt, which remained below 4 billion euros. In 2013, Areva is continuing to implement the Action 2016 plan to keep its turnaround on track. In summary: - Backlog renewed over the year 2012 to euro 45.4 bn thanks to the increase in nuclear order intake; - Sales revenue growth: euro 9.342 bn (+5.3% vs. 2011), led by nuclear and renewables operations; - Very sharp upturn in EBITDA: euro 1.007 bn (+euro 586 m vs. 2011) - Very net improvement in free operating cash flow: -euro 854 m (+euro 512 m vs. 2011); - Back to positive reported operating income: euro 118 m (+euro 1.984 bn vs. 2011); - 2012-2013 floor target for asset disposals

    Full Text Available BackgroundThe effect of yoga in the reduction of depressive symptoms, anxiety, stress, anger as well as in the increased ability of behavioral control has been shown. These effects of yoga are highly relevant for prison inmates who often have poor mental health and low impulse control. While it has been shown that yoga and meditation can be effective in improving subjective well-being, mental health, and executive functioning within prison populations, only a limited number of studies have proved this, using randomized controlled settings.MethodsA total of 152 participants from nine Swedish correctional facilities were randomly assigned to a 10-week yoga group (one class a week; N = 77 or a control group (N = 75. Before and after the intervention period, participants answered questionnaires measuring stress, aggression, affective states, sleep quality, and psychological well-being and completed a computerized test measuring attention and impulsivity.ResultsAfter the intervention period, significant improvements were found on 13 of the 16 variables within the yoga group (e.g., less perceived stress, better sleep quality, an increased psychological and emotional well-being, less aggressive, and antisocial behavior and on two within the control group. Compared to the control group, yoga class participants reported significantly improved emotional well-being and less antisocial behavior after 10 weeks of yoga. They also showed improved performance on the computerized test that measures attention and impulse control.ConclusionIt can be concluded that the yoga practiced in Swedish correctional facilities has positive effects on inmates’ well-being and on considerable risk factors associated with recidivism, such as impulsivity and antisocial behavior. Accordingly, the results show that yoga practice can play an important part in the rehabilitation of prison inmates.

  19. Biomimetic propulsion under random heaving conditions, using active pitch control

    Marine mammals travel long distances by utilizing and transforming wave energy to thrust through proper control of their caudal fin. On the other hand, manmade ships traveling in a wavy sea store large amounts of wave energy in the form of kinetic energy for heaving, pitching, rolling and other ship motions. A natural way to extract this energy and transform it to useful propulsive thrust is by using a biomimetic wing. The aim of this paper is to show how an actively pitched biomimetic wing could achieve this goal when it performs a random heaving motion. More specifically, we consider a biomimetic wing traveling with a given translational velocity in an infinitely extended fluid and performing a random heaving motion with a given energy spectrum which corresponds to a given sea state. A formula is invented by which the instantaneous pitch angle of the wing is determined using the heaving data of the current and past time steps. Simulations are then performed for a biomimetic wing at different heave energy spectra, using an indirect Source-Doublet 3-D-BEM, together with a time stepping algorithm capable to track the random motion of the wing. A nonlinear pressure type Kutta condition is applied at the trailing edge of the wing. With a mollifier-based filtering technique, the 3-D unsteady rollup pattern created by the random motion of the wing is calculated without any simplifying assumptions regarding its geometry. Calculated unsteady forces, moments and useful power, show that the proposed active pitch control always results in thrust producing motions, with significant propulsive power production and considerable beneficial stabilizing action to ship motions. Calculation of the power required to set the pitch angle prove it to be a very small percentage of the useful power and thus making the practical application of the device very tractable.

    Math achievement in elementary school is mediated by performance and growth in number sense during kindergarten. The aim of the present study was to test the effectiveness of a targeted small group number sense intervention for high-risk kindergartners from low-income communities. Children were randomly assigned to one of three groups ( n = 44 in each group): a number sense intervention group, a language intervention group, or a business as usual control group. Accounting for initial skill level in mathematical knowledge, children who received the number sense intervention performed better than controls at immediate post test, with meaningful effects on measures of number competencies and general math achievement. Many of the effects held eight weeks after the intervention was completed, suggesting that children internalized what they had learned. There were no differences between the language and control groups on any math-related measures.

    The objective of this study was to examine the effects of nattokinase supplementation on blood pressure in subjects with pre-hypertension or stage 1 hypertension. In a randomized, double-blind, placebo-controlled trial, 86 participants ranging from 20 to 80 years of age with an initial untreated systolic blood pressure (SBP) of 130 to 159 mmHg received nattokinase (2,000 FU/capsule) or a placebo capsule for 8 weeks. Seventy-three subjects completed the protocol. Compared with the control group, the net changes in SBP and diastolic blood pressure (DBP) were -5.55 mmHg (95% confidence interval [CI], -10.5 to -0.57 mmHg; pnattokinase group compared with the control group (pnattokinase supplementation resulted in a reduction in SBP and DBP. These findings suggest that increased intake of nattokinase may play an important role in preventing and treating hypertension.

    We aimed to evaluate the effectiveness of balneotherapy in fibromyalgia management. Fifty women with fibromyalgia under pharmacological treatment were randomly assigned to either the balneotherapy (25) or the control (25) group. Four patients from the balneotherapy group and one patient from the control group left the study after randomization. The patients in the balneotherapy group (21) had 2 thermomineral water baths daily for 2 weeks in Tuzla Spa Center. The patients in the control group (24) continued to have their medical treatment and routine daily life. An investigator who was blinded to the study arms assessed the patients. All patients were assessed four times; at the beginning of the study, at the end of the 2nd week, the 1st month, and the 3rd month after balneotherapy. Outcome measures of the study were pain intensity, Fibromyalgia Impact Questionnaire (FIQ), Beck Depression Inventory (BDI), patient's global assessment, investigator's global assessment, SF-36 scores, and tender point count. Balneotherapy was found to be superior at the end of the cure period in terms of pain intensity, FIQ, Beck Depression Inventory, patient's global assessment, investigator's global assessment scores, and tender point count as compared to the control group. The superiority of balneotherapy lasted up to the end of the 3rd month, except for the Beck Depression Inventory score and the investigator's global assessment score. Significant improvements were observed in PF, GH, and MH subscales of SF-36 during the study period in the balneotherapy group; however, no such improvement was observed in the control group. Balneotherapy was superior only in VT subscale at the end of therapy and at the end of the third month after the therapy as compared to the controls. It was concluded that balneotherapy provides beneficial effects in patients with fibromyalgia.

    A randomized controlled study (RCT) recently showed that short-term heart rate variability (HRV) biofeedback in addition to standard rehabilitation care for alcohol dependence can reduce craving, anxiety and improve cardiovascular autonomic function. In this one-year follow-up study we aimed to explore whether completion of 2-week HRV-Biofeedback training is associated with long-term abstinence. Furthermore, we sought to identify potential predictors of post-treatment abstinence. We conducted a survey on abstinence in patients with alcohol dependence 1 year after completion of an RCT comparing HRV-biofeedback in addition to inpatient rehabilitation treatment alone (controls). Abstinence rates were compared and analysed for association with demographic data as well as psychometric and autonomic cardiac assessment before and after completion of the biofeedback training using bivariate and multivariate regression analyses. Out of 48 patients who participated in the RCT, 27 patients (9 females, ages 42.9 ± 8.6, mean ± SD) completed our one-year follow-up. When including in the analysis only patients who completed follow-up, the rate of abstinence tended to be higher in patients who underwent HRV-biofeedback 1 year earlier compared to those who received rehabilitative treatment alone (66.7% vs 50%, p = ns). This non-significant trend was also observed in the intention-to-treat analysis where patients who did not participate in the follow-up were assumed to have relapsed (46,7% biofeedback vs. 33.3% controls, p = ns). Neither cardiac autonomic function nor psychometric variables were associated with abstinence 1 year after HRV-biofeedback. Our follow-up study provide a first indication of possible increase in long-term abstinence after HRV-biofeedback for alcohol dependence in addition to rehabilitation. The original randomized controlled trial was registered in the German Clinical Trials Register ( DRKS00004618 ). This one-year follow-up survey has not been

    Full Text Available Abstract Background Many children with asthma live with frequent symptoms and activity limitations, and visits for urgent care are common. Many pediatricians do not regularly meet with families to monitor asthma control, identify concerns or problems with management, or provide self-management education. Effective interventions to improve asthma care such as small group training and care redesign have been difficult to disseminate into office practice. Methods and design This paper describes the protocol for a randomized controlled trial (RCT to evaluate a 12-month telephone-coaching program designed to support primary care management of children with persistent asthma and subsequently to improve asthma control and disease-related quality of life and reduce urgent care events for asthma care. Randomization occurred at the practice level with eligible families within a practice having access to the coaching program or to usual care. The coaching intervention was based on the transtheoretical model of behavior change. Targeted behaviors included 1 effective use of controller medications, 2 effective use of rescue medications and 3 monitoring to ensure optimal control. Trained lay coaches provided parents with education and support for asthma care, tailoring the information provided and frequency of contact to the parent's readiness to change their child's day-to-day asthma management. Coaching calls varied in frequency from weekly to monthly. For each participating family, follow-up measurements were obtained at 12- and 24-months after enrollment in the study during a telephone interview. The primary outcomes were the mean change in 1 the child's asthma control score, 2 the parent's quality of life score, and 3 the number of urgent care events assessed at 12 and 24 months. Secondary outcomes reflected adherence to guideline recommendations by the primary care pediatricians and included the proportion of children prescribed controller medications

    The Consolidated Standards for Reporting of Trials (CONSORT) criteria were published in 1996 to standardize the reporting and improve the quality of clinical trials. Despite having been endorsed by major medical journals and shown to improve the quality of reported trials, neurosurgical journals have yet to formally adopt these reporting criteria. The purpose of this study is to evaluate the quality and reporting of randomized controlled trials (RCTs) in neurosurgery and the factors that may affect the quality of reported trials. The authors evaluated all neurosurgical RCTs published in 2006 and 2007 in the principal neurosurgical journals (Journal of Neurosurgery; Neurosurgery; Surgical Neurology; Journal of Neurology, Neurosurgery, and Psychiatry; and Acta Neurochirurgica) and in 3 leading general medical journals (Journal of the American Medical Association, Lancet, and the New England Journal of Medicine). Randomized controlled trials that addressed operative decision making or the treatment of neurosurgical patients were included in this analysis. The RCT quality was evaluated using the Jadad score and the CONSORT checklist. In 2006 and 2007, 27 RCTs relevant to intracranial neurosurgery were reported. Of these trials, only 59% had a Jadad score ≥ 3. The 3 major medical journals all endorsed the CONSORT guidelines, while none of the neurosurgical journals have adopted these guidelines. Randomized controlled trials published in the 3 major medical journals had a significantly higher mean CONSORT score (mean 41, range 39-44) compared with those published in neurosurgical journals (mean 26.4, range 17-38; p journals (mean 3.42, range 2-5) than neurosurgical journals (mean 2.45, range 1-5; p = 0.05). Despite the growing volume of RCTs in neurosurgery, the quality of reporting of these trials remains suboptimal, especially in the neurosurgical journals. Improved awareness of the CONSORT guidelines by journal editors, reviewers, and authors of these papers could

    Despite the impressive photovoltaic performances with power conversion efficiency beyond 22%, perovskite solar cells are poorly stable under operation, failing by far the market requirements. Various technological approaches have been proposed to overcome the instability problem, which, while delivering appreciable incremental improvements, are still far from a market-proof solution. Here we show one-year stable perovskite devices by engineering an ultra-stable 2D/3D (HOOC(CH2)4NH3)2PbI4/CH3NH3PbI3 perovskite junction. The 2D/3D forms an exceptional gradually-organized multi-dimensional interface that yields up to 12.9% efficiency in a carbon-based architecture, and 14.6% in standard mesoporous solar cells. To demonstrate the up-scale potential of our technology, we fabricate 10 × 10 cm2 solar modules by a fully printable industrial-scale process, delivering 11.2% efficiency stable for >10,000 h with zero loss in performances measured under controlled standard conditions. This innovative stable and low-cost architecture will enable the timely commercialization of perovskite solar cells.

    One and a half year ago the Bonn Electron Stretcher Accelerator ELSA came into operation. Since then detailed machine studies have been performed between 0.5 and 2 GeV. The control system proved to be a valuable tool for operating the machine. Injection into ELSA including the fast extraction out of the 2.5 GeV booster-synchrotron has been investigated. The adjustment of dipoles and quadrupoles has been checked by closed orbit measurements. The slow extraction at a third integer resonance has been studied in detail. Extraction times up to 200 msec with a duty factor of about 35% are possible. For synchrotron radiation experiments the accumulation and storage of high currents up to 275 mA in ELSA was tested. The beam lifetime (1/e point) at 30 mA is in the order of 15 min. (due to vacuum limitations). Since one year the three experiments have been supplied with external beams.

    Time delay in general leads to instability in some systems, while specific feedback with delay can control fluctuated motion in nonlinear deterministic systems to a stable state. In this paper, we consider a stochastic process, i.e., a random walk, and observe its diffusion phenomenon with time-delayed feedback. As a result, the diffusion coefficient decreases with increasing delay time. We analytically illustrate this suppression of diffusion by using stochastic delay differential equations and justify the feasibility of this suppression by applying time-delayed feedback to a molecular dynamics model.

    Full Text Available Objective: To measure length of hospital stay (LHS in patients receiving medication reconciliation. Secondary characteristics included analysis of number of preadmission medications, medications prescribed at admission, number of discrepancies, and pharmacists interventions done and accepted by the attending physician. Methods: A 6 month, randomized, controlled trial conducted at a public teaching hospital in southern Brazil. Patients admitted to general wards were randomized to receive usual care or medication reconciliation, performed within the first 72 hours of hospital admission. Results: The randomization process assigned 68 patients to UC and 65 to MR. LHS was 10±15 days in usual care and 9±16 days in medication reconciliation (p=0.620. The total number of discrepancies was 327 in the medication reconciliation group, comprising 52.6% of unintentional discrepancies. Physicians accepted approximately 75.0% of the interventions. Conclusion: These results highlight weakness at patient transition care levels in a public teaching hospital. LHS, the primary outcome, should be further investigated in larger studies. Medication reconciliation was well accepted by physicians and it is a useful tool to find and correct discrepancies, minimizing the risk of adverse drug events and improving patient safety.

    Full Text Available Abstract Background Residual disability after stroke is substantial; 65% of patients at 6 months are unable to incorporate the impaired upper extremity into daily activities. Task-oriented training programs are rapidly being adopted into clinical practice. In the absence of any consensus on the essential elements or dose of task-specific training, an urgent need exists for a well-designed trial to determine the effectiveness of a specific multidimensional task-based program governed by a comprehensive set of evidence-based principles. The Interdisciplinary Comprehensive Arm Rehabilitation Evaluation (ICARE Stroke Initiative is a parallel group, three-arm, single blind, superiority randomized controlled trial of a theoretically-defensible, upper extremity rehabilitation program provided in the outpatient setting. The primary objective of ICARE is to determine if there is a greater improvement in arm and hand recovery one year after randomization in participants receiving a structured training program termed Accelerated Skill Acquisition Program (ASAP, compared to participants receiving usual and customary therapy of an equivalent dose (DEUCC. Two secondary objectives are to compare ASAP to a true (active monitoring only usual and customary (UCC therapy group and to compare DEUCC and UCC. Methods/design Following baseline assessment, participants are randomized by site, stratified for stroke duration and motor severity. 360 adults will be randomized, 14 to 106 days following ischemic or hemorrhagic stroke onset, with mild to moderate upper extremity impairment, recruited at sites in Atlanta, Los Angeles and Washington, D.C. The Wolf Motor Function Test (WMFT time score is the primary outcome at 1 year post-randomization. The Stroke Impact Scale (SIS hand domain is a secondary outcome measure. The design includes concealed allocation during recruitment, screening and baseline, blinded outcome assessment and intention to treat analyses. Our primary

    Full Text Available Abstract Background Besides cognitive decline, Alzheimer's disease (AD leads to physical disability, need for help and permanent institutional care. The trials investigating effects of exercise rehabilitation on physical functioning of home-dwelling older dementia patients are still scarce. The aim of this study is to investigate the effectiveness of intensive exercise rehabilitation lasting for one year on mobility and physical functioning of home-dwelling patients with AD. Methods During years 2008-2010, patients with AD (n = 210 living with their spousal caregiver in community are recruited using central AD registers in Finland, and they are offered exercise rehabilitation lasting for one year. The patients are randomized into three arms: 1 tailored home-based exercise twice weekly 2 group-based exercise twice weekly in rehabilitation center 3 control group with usual care and information of exercise and nutrition. Main outcome measures will be Guralnik's mobility and balance tests and FIM-test to assess physical functioning. Secondary measures will be cognition, neuropsychiatric symptoms according to the Neuropsychiatric Inventory, caregivers' burden, depression and health-related quality of life (RAND-36. Data concerning admissions to institutional care and the use and costs of health and social services will be collected during a two year follow-up. Discussion To our knowledge this is the first large scale trial exploring whether home-dwelling patients with AD will benefit from intense and long-lasting exercise rehabilitation in respect to their mobility and physical functioning. It will also provide data on cost-effectiveness of the intervention. Trial registration ACTRN12608000037303

    Objective This analysis focuses on 1-year maternal and infant follow-up of a randomized trial that tested a weight management intervention conducted during pregnancy. Methods We randomly assigned 114 women with obesity (mean BMI 36.7 kg/m2) at a mean of 15 weeks’ gestation to a weight management intervention or usual care control condition. The intervention ended at delivery and resulted in less gestational weight gain and a lower proportion of large-for-gestational age newborns among intervention compared to control participants. The primary outcome at 12 months postpartum was maternal weight. Secondary outcomes included infant weight-for-age and weight-for-length z-scores. Results At 1 year, mothers in the intervention group weighed 96.3±18.6 kg, and in the control group, 99.7±19.2 kg. There was no significant difference between groups in change in weight from randomization to 1-year postpartum (b=-0.47, 95% CI [-4.03, 3.08]. There was a significant main effect of group for infant weight-for-age z-score (b=-0.40, 95% CI [-0.75,-0.05]) but not infant weight-for-length z-scores (b=-0.20, 95% CI [-0.59,0.20]. Conclusions A gestational weight management intervention did not influence maternal weight or infant weight-for-length at 1-year postpartum. Future studies may be warranted to determine if extending prenatal interventions into the postpartum period would be beneficial for maternal and infant outcomes. PMID:27670399

    Practicing a health-promoting lifestyle is believed to be effective for delaying or preventing the onset of diabetes. However, although empowerment interventions have proven effective for encouraging the adoption of a health-promoting lifestyle in people with diabetes, these interventions are rarely promoted to people with prediabetes. The aims of this study were to develop an empowerment program for people with prediabetes and to examine its efficacy in terms of the adoption of a health-promoting lifestyle and improvements in blood sugar, body mass index, and self-efficacy. A randomized controlled trial was conducted between May and December 2013. A convenience sample of people with a fasting blood sugar level of 100-125 mg/dl during the previous 3 months was recruited from the health examination center of a hospital in Kaohsiung, Taiwan. Participants were assigned to either the experimental group or the control group using block randomization with a block size of 8. The experimental group (n = 38) participated in a 4-month empowerment program (the ABC empowerment program), which encouraged participants to practice a health-promoting lifestyle in three phases: awareness raising, behavior building, and results checking. The control group (n = 40) received routine clinical care. Statistical analyses included descriptive statistics, independent t test, paired t test, and generalized estimated equations. After controlling for the differences at baseline and considering the interaction between group and time from baseline to 1 week and 3 months after completing the intervention, the generalized estimating equation showed significantly larger improvements in a health-promoting lifestyle, blood sugar, and self-efficacy in the experimental group than in the control group (p empowerment program was shown to have short-term, positive effects on behavioral, physical, and psychosocial outcomes in a Taiwan population with prediabetes.

    Objective To determine the efficacy of yoga in alleviating VMS frequency and bother. Methods Three by two factorial design, randomized, controlled. Eligible women were randomized to yoga (n=107), exercise (n=106), or usual activity (n=142), and were simultaneously randomized to double-blind comparison of omega-3 fatty acid (n=177) or placebo (n=178) capsules. Yoga intervention was twelve, weekly, 90-minute yoga classes with daily home practice. Primary outcomes were VMS frequency and bother assessed by daily diaries at baseline, 6, and 12 weeks. Secondary outcomes included insomnia symptoms (Insomnia Severity Index) at baseline and 12 weeks. Results Among 249 randomized women, 237 (95%) completed 12-week assessments. Mean baseline VMS frequency was 7.4/day (95% CI 6.6, 8.1) in the yoga group and 8.0/day (95% CI 7.3, 8.7) in the usual activity group. Intent-to-treat analyses included all participants with response data (n=237). There was no difference between intervention groups in change in VMS frequency from baseline to 6 and 12 weeks (mean difference (yoga – usual activity) from baseline −0.3 (95% CI −1.1, 0.5) at 6 weeks and −0.3 (95% CI −1.2, 0.6) at 12 weeks (p=0.119 across both time points). Results were similar for VMS bother. At week 12, yoga was associated with an improvement in insomnia symptoms (mean difference [yoga-usual activity] in change –Insomnia Severity Index, 1.3 [95% CI −2.5, −0.1][p=0.007]). Conclusion Among healthy women, 12 weeks of yoga class plus home practice compared with usual activity did not improve VMS frequency or bother, but reduced insomnia symptoms. PMID:24045673

    Oral propranolol has been used to treat complicated infantile hemangiomas, although data from randomized, controlled trials to inform its use are limited. We performed a multicenter, randomized, double-blind, adaptive, phase 2-3 trial assessing the efficacy and safety of a pediatric-specific oral propranolol solution in infants 1 to 5 months of age with proliferating infantile hemangioma requiring systemic therapy. Infants were randomly assigned to receive placebo or one of four propranolol regimens (1 or 3 mg of propranolol base per kilogram of body weight per day for 3 or 6 months). A preplanned interim analysis was conducted to identify the regimen to study for the final efficacy analysis. The primary end point was success (complete or nearly complete resolution of the target hemangioma) or failure of trial treatment at week 24, as assessed by independent, centralized, blinded evaluations of standardized photographs. Of 460 infants who underwent randomization, 456 received treatment. On the basis of an interim analysis of the first 188 patients who completed 24 weeks of trial treatment, the regimen of 3 mg of propranolol per kilogram per day for 6 months was selected for the final efficacy analysis. The frequency of successful treatment was higher with this regimen than with placebo (60% vs. 4%, P<0.001). A total of 88% of patients who received the selected propranolol regimen showed improvement by week 5, versus 5% of patients who received placebo. A total of 10% of patients in whom treatment with propranolol was successful required systemic retreatment during follow-up. Known adverse events associated with propranolol (hypoglycemia, hypotension, bradycardia, and bronchospasm) occurred infrequently, with no significant difference in frequency between the placebo group and the groups receiving propranolol. This trial showed that propranolol was effective at a dose of 3 mg per kilogram per day for 6 months in the treatment of infantile hemangioma. (Funded by

    Existing remedies for controlling pseudofolliculitis barbae (PFB) are sometimes helpful; however the positive effects are often short lived. The only definitive cure for PFB is permanent removal of the hair follicle. Our aim was to compare the efficacy of the Alexandrite laser with the intense pulsed light system in the treatment of PFB and to follow up the recurrence. Twenty male patients seeking laser hair removal for the treatment of PFB were enrolled in this study. One half of the face was treated with the long-pulse Alexandrite laser and the other half was treated with the IPL system randomly. The treatment outcome and any complications were observed and followed up for one year. All patients exhibited a statistically significant decrease in the numbers of papules. Our results showed that the Alexandrite-treated side needed seven sessions to reach about 80% improvement, while the IPL-treated side needed 10-12 sessions to reach about 50% improvement. During the one year follow up period, the Alexandrite-treated side showed recurrence in very minimal areas, while the IPL-treated side showed recurrence in bigger areas. Our results showed that both systems might improve PFB but Alexandrite laser was more effective at reducing PFB than IPL.

    The objective of this study was to test the biofilm-controlling properties of N-halamine antimicrobial dental unit waterline (DUWL) tubing (T) tubing, without recharging over one year, compared to a control line (C). A simulated clinical model was used to pump ultrapure water through T and C lines at a rate of 1.4 mL/min, five minutes on, 15 minutes off, eight hours/day, five days a week. Samples of source water, effluent from T and C, and from the stagnant water in the carboy (liquid container) after bench work was completed (S2), were collected aseptically, serially diluted, and cultured on R2A agar for seven days every six weeks. SEM images of the inside surfaces of detached tubing sections were also taken. The carboy was rinsed with a 1:10 dilution of sodium hypochlorite after six months. Means of log transformed CFU values obtained in triplicate were paired by T and C lines across months for comparison by paired Student's t-tests. An increase in effluent and carboy bacterial counts were noted after six months, but decreased after bleach rinse of the carboy. No significant difference (p > 0.25) between T and C lines were observed; similarly, T and carboy were not significantly different (p > 0.30). SEM images showed biofilm attachment on the inside surface of C after two months, but not on T. Organisms identified in the effluent reflected those in the source carboy. No biofilm attachment was detected on the N-halamine test line after 12 months, indicating its antimicrobial properties were retained. Further evaluation is recommended to determine the optimal recharge interval for N-halamine DUWL tubing when ultrapure source water is used.

    The random fiber laser (RFL) which is a milestone in laser physics and nonlinear optics, has attracted considerable attention recently. Most previous RFLs are based on distributed feedback of Rayleigh scattering amplified through stimulated Raman/Brillouin scattering effect in single mode fibers, which required long-distance (tens of kilometers) single mode fibers and high threshold up to watt-level due to the extremely small Rayleigh scattering coefficient of the fiber. We proposed and demonstrated a half-open cavity RFL based on a segment of a artificially controlled backscattering SMF(ACB-SMF) with a length of 210m, 310m or 390m. A fiber Bragg grating with the central wavelength of 1530nm and a segment of ACB-SMF forms the half-open cavity. The proposed RFL achieves the threshold of 25mW, 30mW and 30mW, respectively. Random lasing at the wavelength of 1530nm and the extinction ratio of 50dB is achieved when a segment of 5m EDF is pumped by a 980nm LD in the RFL. Another half-open cavity RFL based on a segment of a artificially controlled backscattering EDF(ACBS-EDF) is also demonstrated without an ACB-SMF. The 3m ACB-EDF is fabricated by using the femtosecond laser with pulse energy of 0.34mJ which introduces about 50 reflectors in the EDF. Random lasing at the wavelength of 1530nm is achieved with the output power of 7.5mW and the efficiency of 1.88%. Two novel RFLs with much short cavities have been achieved with low threshold and high efficiency.

    Study Objectives: To evaluate the efficacy of mindfulness meditation for the treatment of chronic insomnia. Design: Three-arm, single-site, randomized controlled trial. Setting: Academic medical center. Participants: Fifty-four adults with chronic insomnia. Interventions: Participants were randomized to either mindfulness-based stress reduction (MBSR), mindfulness-based therapy for insomnia (MBTI), or an eight-week self-monitoring (SM) condition. Measurements and Results: Patient-reported outcome measures were total wake time (TWT) from sleep diaries, the pre-sleep arousal scale (PSAS), measuring a prominent waking correlate of insomnia, and the Insomnia Severity Index (ISI) to determine remission and response as clinical endpoints. Objective sleep measures were derived from laboratory polysomnography and wrist actigraphy. Linear mixed models showed that those receiving a meditation-based intervention (MBSR or MBTI) had significantly greater reductions on TWT minutes (43.75 vs 1.09), PSAS (7.13 vs 0.16), and ISI (4.56 vs 0.06) from baseline-to-post compared to SM. Post hoc analyses revealed that each intervention was superior to SM on each of the patient-reported measures, but no significant differences were found when comparing MBSR to MBTI from baseline-to-post. From baseline to 6-month follow-up, MBTI had greater reductions in ISI scores than MBSR (P insomnia and could provide an alternative to traditional treatments for insomnia.

    Childbirth is a demanding event in a woman's life. The aim of this study was to explore whether a brief intervention in the form of an antenatal course in self-hypnosis to ease childbirth could improve the childbirth experience. In a randomized, controlled, single-blinded trial, 1,222 healthy nulliparous women were allocated to one of three groups during pregnancy: A hypnosis group participating in three 1-hour sessions teaching self-hypnosis to ease childbirth, a relaxation group receiving three 1-hour lessons in various relaxation methods and Mindfulness, and a usual care group receiving ordinary antenatal care only. Wijmas Delivery Expectancy/Experience Questionnaire (W-DEQ) was used to measure the childbirth experience 6 weeks postpartum. The intention-to-treat analysis indicated that women in the hypnosis group experienced their childbirth as better compared with the other two groups (mean W-DEQ score of 42.9 in the Hypnosis group, 47.2 in the Relaxation group, and 47.5 in the Care as usual group (p = 0.01)). The tendency toward a better childbirth experience in the hypnosis group was also seen in subgroup analyses for mode of delivery and for levels of fear. In this large randomized controlled trial, a brief course in self-hypnosis improved the women's childbirth experience. © 2013, Copyright the Authors Journal compilation © 2013, Wiley Periodicals, Inc.

    Full Text Available Preterm birth affects about 10% of infants born in the United States. Massage therapy is being used in some neonatal intensive care units for its potential beneficial effects on preterm infants. This article reviews published randomized controlled trials on the effects of massage in preterm infants. Most studies evaluating the effect of massage in weight gain in premature infants suggest a positive effect on weight gain. Increase in vagal tone has been reported in infants who receive massage and has been suggested as a possible mechanism for improved weight gain. More studies are needed on the underlying mechanisms of the effects of massage therapy on weight gain in preterm infants. While some trials suggest improvements in developmental scores, decreased stress behavior, positive effects on immune system, improved pain tolerance and earlier discharge from the hospital, the number of such studies is small and further evidence is needed. Further studies, including randomized controlled trials, are needed on the effects of massage in preterm infants.

    To estimate the efficacy of moxibustion between 34 and 38 weeks of gestation to facilitate the cephalic version of fetuses in breech presentation and the acceptability of this method by women. We conducted a randomized controlled trial in a Swiss university hospital maternity unit. We proposed to stimulate the acupoint BL 67 by moxibustion daily for 2 weeks for 212 consenting women between 34 and 36 weeks of gestation with a single fetus in breech presentation. We did the intervention three times weekly in the hospital and a teaching session and information leaflet on the technique for additional daily therapy at home. The control group received expectant management care. The availability of external cephalic version was maintained for both groups. The main outcome measure was the comparison of the proportion of women with cephalic presentation at delivery. Baseline characteristics were similar between groups, except more nulliparous women were randomized to moxibustion. The percentage of versions was similar between groups: 18% in the moxibustion group compared with 16% in the control group (relative risk 1.12, 95% confidence interval 0.62 to 2.03). Adjustment for the imbalance in parity did not change these results. The frequency of cesarean delivery was similar (64% compared with 58% in the moxibustion group and the control group, respectively). Acceptability of the intervention and women's perceptions of moxibustion were favorable. We observed no beneficial effect of moxibustion to facilitate the cephalic version of fetuses in breech presentation. Despite this lack of proven effectiveness, women had positive opinions on the intervention. ClinicalTrials.gov, www.clinicaltrials.gov,NCT00890474. I.

    Orthostatic intolerance is a syndrome characterized by chronic orthostatic symptoms of light-headedness, fatigue, nausea, orthostatic tachycardia, and aggravated norepinephrine levels while standing. The aim of this study was to assess the protective effect of exercise endurance training on orthostatic symptoms and to examine its usefulness in the treatment of orthostatic intolerance. 2768 military recruits were screened for orthostatic intolerance by questionnaire. Tilt-table testing identified 36 cases of orthostatic intolerance out of the 2768 soldiers. Subsequently, 31 of these subjects with orthostatic intolerance entered a randomized, controlled trial. The patients were allocated randomly to either a "training" (3 months jogging) or a "control" group. The influence of exercise training on orthostatic intolerance was assessed by determination of questionnaire scores and tilt-table testing before and after intervention. After training, only 6 individuals of 16 still had orthostatic intolerance compared with 10 of 11 in the control group. The Fisher exact test showed a highly significant difference in diagnosis between the 2 groups (P=0.008) at the end of the study. Analysis of the questionnaire-score showed significant interaction between time and group (P=0.001). The trained subjects showed an improvement in the average symptom score from 1.79+/-0.4 to 1.04+/-0.4, whereas the control subjects showed no significant change in average symptom score (2.09+/-0.6 and 2.14+/-0.5, respectively). Our data demonstrate that endurance exercise training leads to an improvement of symptoms in the majority of patients with orthostatic intolerance. Therefore, we suggest that endurance training should be considered in the treatment of orthostatic intolerance patients.

    Full Text Available Abstract Background Work-related musculoskeletal disorders (MSDs are an important cause of functional impairments and disability among construction workers. An improved understanding of MSDs in different construction occupations is likely to be of value for selecting preventive measures. This study aimed to survey the prevalence of symptoms of MSDs, the work-relatedness of the symptoms and the problems experienced during work among two construction occupations: bricklayers and supervisors. Methods We randomly selected 750 bricklayers and 750 supervisors resident in the Netherlands in December 2009. This sample was surveyed by means of a baseline questionnaire and a follow-up questionnaire one year later. The participants were asked about complaints of the musculoskeletal system during the last six months, the perceived work-relatedness of the symptoms, the problems that occurred during work and the occupational tasks that were perceived as causes or aggravating factors of the MSD. Results Baseline response rate was 37%, follow-up response was 80%. The prevalence of MSDs among 267 bricklayers and 232 supervisors was 67% and 57%, respectively. Complaints of the back, knee and shoulder/upper arm were the most prevalent among both occupations. Irrespective of the body region, most of the bricklayers and supervisors reported that their complaints were work-related. Complaints of the back and elbow were the most often reported among the bricklayers during work, whereas lower arm/wrist and upper leg complaints were the most often reported among the supervisors. In both occupations, a majority of the participants perceived several occupational physical tasks and activities as causes or aggravating factors for their MSD. Recurrent complaints at follow-up were reported by both bricklayers (47% of the complaints and supervisors (31% of the complaints. Participants in both occupations report that mainly back and knee complaints result in additional problems

    The aim of this study was to investigate the immediate and long-term effects of a one-year multimodal program, with the addition of upper cervical manipulative therapy, on fibromyalgia management outcomes in addition to three-dimensional (3D) postural measures. This randomized clinical trial with one-year follow-up was completed at the research laboratory of our university. A total of 120 (52 female) patients with fibromyalgia syndrome (FMS) and definite C1-2 joint dysfunction were randomly assigned to the control or an experimental group. Both groups received a multimodal program; additionally, the experimental group received upper cervical manipulative therapy. Primary outcomes were the Fibromyalgia Impact Questionnaire (FIQ), whereas secondary outcomes included Pain Catastrophizing Scale (PCS), algometric score, Pittsburgh Sleep Quality Index (PSQI), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and 3D postural measures. Measures were assessed at three time intervals: baseline, 12 weeks, and 1 year after the 12-week follow-up. The general linear model with repeated measures indicated a significant group × time effect in favor of the experimental group on the measures of 3D postural parameters (P < .0005), FIQ (P < .0005), PCS (P < .0005), algometric score (F = P < .0005), PSQI (P < .0005), BAI (P < .0005), and BDI (P < .0005). The addition of the upper cervical manipulative therapy to a multimodal program is beneficial in treating patients with FMS.

    A worksite prevention program was developed to promote the work ability of construction workers and thereby prolong a healthy working life. The objective of this paper is to present the design of a randomized controlled trial evaluating the effectiveness of that intervention program compared with usual care for construction workers. The study is designed as a randomized controlled trial with a follow-up of one year. Employees eligible for this study are construction workers performing actual construction work. The worksite intervention will be compared with usual care. This intervention was developed by using the Intervention Mapping approach and consists of the following components: (1) two individual training sessions of a physical therapist to lower the physical workload, (2) a Rest-Break tool to improve the balance between work and recovery, and (3) two empowerment training sessions to increase the influence of the construction workers at the worksite. Outcome measures are assessed at baseline, 3, 6, and 12 months. The primary outcome measures of this study are work ability and health-related quality of life. Secondary outcome measures include need for recovery, musculoskeletal complaints, work engagement and self efficacy. Cost-effectiveness will be evaluated from the company perspective. Moreover, a process evaluation will be conducted. The feasibility of the intervention and the study has been enhanced by creating an intervention program that explicitly appeals to construction workers and will not interfere too much with the ongoing construction. The feasibility and effectiveness of this worksite prevention program will be investigated by means of an effect- and a process evaluation. If proven effective, this worksite prevention program can be implemented on a larger scale within the construction industry. NTR1278.

    A randomized waitlist-controlled design (n = 74) examined the efficacy of Reconsolidation of Traumatic Memories (RTM) among male veterans with current-month flashbacks and nightmares. Volunteers were randomly assigned to immediate treatment (three 120-minute sessions of RTM), or to a 3-week waiting condition before receiving the RTM treatment. Blinded psychometricians evaluated the symptoms at intake, 2 weeks, and 6 weeks post. Wait-listed participants were re-evaluated and then treated. Sixty-five volunteers completed the treatment. Of those treated, 46 (71%) lost DSM diagnosis for post-traumatic stress disorder (PTSD) by one of the following definitions: 42 persons (65%) were in complete remission (PTSD Symptom Scale Interview (PSS-I) ≤ 20 and DSM criteria not met). Four others (6%) lost the DSM diagnosis or were otherwise sub-clinical by dichotomous criteria (PSS-I < 20 and absence of flashbacks and nightmares) but non-ambiguous on the PTSD Checklist Military Version measures. Within-group RTM effect sizes (Hedges' g) for PSS-I score changes ranged from 1.5 to 2.2. The between-group comparison between the treatment group and the untreated controls was significant (p < .001) with an effect size equivalent to two standard deviations (g = -2.121; 95% CI [-4.693-0.453]). Patient satisfaction with the intervention was high. RTM shows promise as a brief, cost-effective intervention for PTSD characterized primarily by intrusive symptoms. Clinical or methodological significance of this article: The article provides evidence to support a fast (5 hours or fewer) robust intervention for PTSD characterized by intrusive symptoms including current-month flashbacks, nightmares, and accompanied by sympathetic arousal in response to trauma narratives. The intervention is well tolerated and has demonstrated efficacy up to one year.

    Full Text Available Abstract Background Little is known about the course and outcome of untreated anxiety and depression in patients with and without a self-perceived need for care. The aim of the present study was to examine the one-year course of untreated anxiety and depression, and to determine predictors of a poor outcome. Method Baseline and one-year follow-up data were used of 594 primary care patients with current anxiety or depressive disorders at baseline (established by the Composite Interview Diagnostic Instrument (CIDI, from the Netherlands Study of Depression and Anxiety (NESDA. Receipt of and need for care were assessed by the Perceived Need for Care Questionnaire (PNCQ. Results In depression, treated and untreated patients with a perceived treatment need showed more rapid symptom decline but greater symptom severity at follow-up than untreated patients without a self-perceived mental problem or treatment need. A lower education level, lower income, unemployment, loneliness, less social support, perceived need for care, number of somatic disorders, a comorbid anxiety and depressive disorder and symptom severity at baseline predicted a poorer outcome in both anxiety and depression. When all variables were considered at the same time, only baseline symptom severity appeared to predict a poorer outcome in anxiety. In depression, a poorer outcome was also predicted by more loneliness and a comorbid anxiety and depressive disorder. Conclusion In clinical practice, special attention should be paid to exploring the need for care among possible risk groups (e.g. low social economic status, low social support, and support them in making an informed decision on whether or not to seek treatment.

    Turnover among direct support professionals (DSPs) in community support settings for individuals with intellectual and developmental disabilities (IDD) has been regarded as a challenge since tracking of this workforce began in the 1980s. This study utilized a group randomized controlled design to test the effects of a competency-based training intervention for DSPs on site-level turnover rates over a one year period. Results suggested that, compared with the control group, sites receiving the training intervention experienced a significant decrease in annual turnover, when multiple factors were controlled. Implications, including the importance of considering quality training as a long term organizational investment and intervention to reduce turnover, are discussed.

    Effective alternatives to long waiting lists for entry into methadone hydrochloride maintenance treatment are needed to reduce the complications of continuing heroin dependence and to increase methadone treatment entry. To compare the effectiveness of interim methadone maintenance with that of the usual waiting list condition in facilitating methadone treatment entry and reducing heroin and cocaine use and criminal behavior. Randomized, controlled, clinical trial using 2 conditions, with treatment assignment on a 3:2 basis to interim maintenance-waiting list control. A methadone treatment program in Baltimore. A total of 319 individuals meeting the criteria for current heroin dependence and methadone maintenance treatment. Participants were randomly assigned to either interim methadone maintenance, consisting of an individually determined methadone dose and emergency counseling only for up to 120 days, or referral to community-based methadone treatment programs. Entry into comprehensive methadone maintenance therapy at 4 months from baseline; self-reported days of heroin use, cocaine use, and criminal behavior; and number of urine drug test results positive for heroin and cocaine at the follow-up interview conducted at time of entry into comprehensive methadone treatment (or at 4 months from baseline for participants who did not enter regular treatment). Significantly more participants assigned to the interim methadone maintenance condition entered comprehensive methadone maintenance treatment by the 120th day from baseline (75.9%) than those assigned to the waiting list control condition (20.8%) (Pmethadone maintenance results in a substantial increase in the likelihood of entry into comprehensive treatment, and is an effective means of reducing heroin use and criminal behavior among opioid-dependent individuals awaiting entry into a comprehensive methadone treatment program.

    There is no consensus on the most effective pain management for neonatal circumcision. We sought to compare different modalities. This is a double-blinded randomized controlled trial comparing 3 combination analgesics used during circumcision (EMLA + sucrose; EMLA + sucrose + dorsal penile nerve block [DPNB]; EMLA + sucrose + ring block [RB]) with the traditional topical analgesic cream EMLA alone. The trial was set in the normal nursery of a teaching hospital. The sample included 70 healthy male newborns, randomly assigned to intervention and control groups at a 2:1 ratio. Infants were videotaped (face and torso) during the procedure for assessment of pain by 2 blinded, independent reviewers. The primary outcome measure is the Neonatal Infant Pain Scale score. Secondary outcomes include heart rate, oxygen saturation, and crying time. Neonatal Infant Pain Scale scores were significantly lower in the intervention groups (EMLA + sucrose, mean [SD]: 3.1 [1.33]; EMLA + sucrose + DPNB: 3 [1.33]; EMLA + sucrose + RB: 2.45 [1.27]) compared with the control (5.5 [0.53]). Between-group analyses showed RB + EMLA + sucrose to be significantly more effective than EMLA + sucrose; EMLA + sucrose + DPNB ( P = .009 and P = .002, respectively). Interrater reliability was κ = 0.843. Significant increase in heart rate (139.27 [9.63] to 163 [13.23] beats per minute) and crying time (5.78 [6.4] to 45.37 [12.39] seconds) were noted in the EMLA group. During neonatal circumcision in boys, the most effective analgesia is RB combined with oral sucrose and EMLA cream. Copyright © 2017 by the American Academy of Pediatrics.

    Volunteering is presumed to confer health benefits, but interventions to encourage older adults to volunteer are sparse. Therefore, a randomized controlled trial with 280 community-dwelling older German adults was conducted to test the effects of a theory-based social-cognitive intervention against a passive waiting-list control group and an active control intervention designed to motivate physical activity. Self-reports of weekly volunteering minutes were assessed at baseline (5 weeks before the intervention) as well as 2 and 6 weeks after the intervention. Participants in the treatment group increased their weekly volunteering minutes to a greater extent than participants in the control groups 6 weeks after the intervention. We conclude that a single, face-to-face group session can increase volunteering among older community-dwelling adults. However, the effects need some time to unfold because changes in volunteering were not apparent 2 weeks after the intervention. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

    Patients suffering from neurogenic claudication due to lumbar spinal stenosis (LSS) often experience moderate to severe pain and significant functional disability. Neurogenic claudication results from progressive degenerative changes in the spine, and most often affects the elderly. Both the MILD® procedure and epidural steroid injections (ESIs) offer interventional pain treatment options for LSS patients experiencing neurogenic claudication refractory to more conservative therapies. MILD provides an alternative to ESIs via minimally invasive lumbar decompression. Prospective, multi-center, randomized controlled clinical trial. Twenty-six US interventional pain management centers. To compare patient outcomes following treatment with either MILD (treatment group) or ESIs (active control group) in LSS patients with neurogenic claudication and verified ligamentum flavum hypertrophy. This prospective, multi-center, randomized controlled clinical trial includes 2 study arms with a 1-to-1 randomization ratio. A total of 302 patients were enrolled, with 149 randomized to MILD and 153 to the active control. Six-month follow-up has been completed and is presented in this report. In addition, one year follow-up will be conducted for patients in both study arms, and supplementary 2 year outcome data will be collected for patients in the MILD group only. Outcomes are assessed using the Oswestry Disability Index (ODI), numeric pain rating scale (NPRS) and Zurich Claudication Questionnaire (ZCQ). Primary efficacy is the proportion of ODI responders, tested for statistical superiority of the MILD group versus the active control group. ODI responders are defined as patients achieving the validated Minimal Important Change (MIC) of =10 point improvement in ODI from baseline to follow-up. Similarly, secondary efficacy includes proportion of NPRS and ZCQ responders using validated MIC thresholds. Primary safety is the incidence of device or procedure-related adverse events in each

    Dysphagia is very common in children with neurological disabilities. These patients usually suffer from respiratory and nutritional problems. The videofluoroscopic swallowing study (VFSS) is the most recommended test to evaluate dysphagia, as it shows the real situation during swallowing. To analyse the results obtained in our centre after one year of the implementation of VFSS, the clinical improvement after confirmation, and the prescription of an individualised treatment for the patients affected. VFSS performed in the previous were collected. The following variables were analysed: age, pathology, degree of neurological damage, oral and pharyngeal and/or oesophageal dysphagia and its severity, aspirations, prescribed treatment, and nutritional and respiratory improvement after diagnosis. A statistical analysis was performed using SPSS v21. A total of 61 VFSS were performed. Dysphagia was detected in more than 70%, being moderate-severe in 58%. Aspirations and/or penetrations were recorded in 59%, of which 50% were silent. Adapted diet was prescribed to 56%, and gastrostomy was performed on 13 (21%) patients. A statistical association was found between neurological disease and severity of dysphagia. The degree of motor impairment is related to the presence of aspirations. After VFSS evaluation and treatment adjustment, nutritional improvement was found in Z-score of weight (+0.3SD) and BMI (+0.4SD). There was respiratory improvement in 71% of patients with dysphagia being controlled in the Chest Diseases Department. After implementation of VFSS, a high percentage of patients were diagnosed and benefited from a correct diagnosis and treatment. VFSS is a fundamental diagnostic test that should be included in paediatric centres as a diagnostic method for children with suspected dysphagia. Copyright © 2017.

    The physical quality index (QI) of radiological devices summarises in a single numerical value between 0 and 1 the results of constancy tests. The aim of this paper is to illustrate the results of the use of such an index on all public radiological devices in the Livorno province over one year. The quality index was calculated for 82 radiological devices of a wide range of types by implementing its algorithm in a spreadsheet-based software for the automatic handling of quality control data. The distribution of quality index values was computed together with the associated statistical quantities. This distribution is strongly asymmetrical, with a sharp peak near the highest QI values. The mean quality index values for the different types of device show some inhomogeneity: in particular, mammography and panoramic dental radiography devices show far lower quality than other devices. In addition, our analysis has identified the parameters that most frequently do not pass the quality tests for each type of device. Finally, we sought some correlation between quality and age of the device, but this was poorly significant. The quality index proved to be a useful tool providing an overview of the physical conditions of radiological devices. By selecting adequate QI threshold values for, it also helps to decide whether a given device should be upgraded or replaced. The identification of critical parameters for each type of device may be used to improve the definition of the QI by attributing greater weights to critical parameters, so as to better address the maintenance of radiological devices.

  5. The Social Origins of Sustained Attention in One-Year-Old Human Infants.

    The ability to sustain attention is a major achievement in human development and is generally believed to be the developmental product of increasing self-regulatory and endogenous (i.e., internal, top-down, voluntary) control over one's attention and cognitive systems [1-5]. Because sustained attention in late infancy is predictive of future development, and because early deficits in sustained attention are markers for later diagnoses of attentional disorders [6], sustained attention is often viewed as a constitutional and individual property of the infant [6-9]. However, humans are social animals; developmental pathways for seemingly non-social competencies evolved within the social group and therefore may be dependent on social experience [10-13]. Here, we show that social context matters for the duration of sustained attention episodes in one-year-old infants during toy play. Using head-mounted eye tracking to record moment-by-moment gaze data from both parents and infants, we found that when the social partner (parent) visually attended to the object to which infant attention was directed, infants, after the parent's look, extended their duration of visual attention to the object. Looks to the same object by two social partners is a well-studied phenomenon known as joint attention, which has been shown to be critical to early learning and to the development of social skills [14, 15]. The present findings implicate joint attention in the development of the child's own sustained attention and thus challenge the current understanding of the origins of individual differences in sustained attention, providing a new and potentially malleable developmental pathway to the self-regulation of attention.

    Full Text Available Dansgaard–Oeschger (DO events constitute the most pronounced mode of centennial to millennial climate variability of the last glacial period. Since their discovery, many decades of research have been devoted to understand the origin and nature of these rapid climate shifts. In recent years, a number of studies have appeared that report emergence of DO-type variability in fully coupled general circulation models via different mechanisms. These mechanisms result in the occurrence of DO events at varying degrees of regularity, ranging from periodic to random. When examining the full sequence of DO events as captured in the North Greenland Ice Core Project (NGRIP ice core record, one can observe high irregularity in the timing of individual events at any stage within the last glacial period. In addition to the prevailing irregularity, certain properties of the DO event sequence, such as the average event frequency or the relative distribution of cold versus warm periods, appear to be changing throughout the glacial. By using statistical hypothesis tests on simple event models, we investigate whether the observed event sequence may have been generated by stationary random processes or rather was strongly modulated by external factors. We find that the sequence of DO warming events is consistent with a stationary random process, whereas dividing the event sequence into warming and cooling events leads to inconsistency with two independent event processes. As we include external forcing, we find a particularly good fit to the observed DO sequence in a model where the average residence time in warm periods are controlled by global ice volume and cold periods by boreal summer insolation.

    To evaluate the effectiveness of a group-based self-management program for people with chronic fatigue syndrome. A randomized controlled trial. Four mid-sized towns in southern Norway and two suburbs of Oslo. A total of 137 adults with chronic fatigue syndrome. A self-management program including eight biweekly meetings of 2.5 hours duration. The control group received usual care. Primary outcome measure: Medical Outcomes Study-Short Form-36 physical functioning subscale. Fatigue severity scale, self-efficacy scale, physical and mental component summary of the Short Form-36, and the illness cognition questionnaire (acceptance subscale). Assessments were performed at baseline, and at six-month and one-year follow-ups. At the six-month follow-up, a significant difference between the two groups was found concerning fatigue severity ( p = 0.039) in favor of the control group, and concerning self-efficacy in favor of the intervention group ( p = 0.039). These significant differences were not sustained at the one-year follow-up. No significant differences were found between the groups concerning physical functioning, acceptance, and health status at any of the measure points. The drop-out rate was 13.9% and the median number of sessions attended was seven (out of eight). The evaluated self-management program did not have any sustained effect, as compared with receiving usual care.

    [Purpose] The purpose of this study was to determine the effects of dry cupping on pain and function of patients with plantar fasciitis. [Subjects and Methods] Twenty-nine subjects (age 15 to 59 years old, 20 females and 9 males), randomly assigned into the two groups (dry cupping therapy and electrical stimulation therapy groups), participated in this study. The research design was a randomized controlled trial (RCT). Treatments were provided to the subjects twice a week for 4 weeks. Outcome measurements included the Visual Analogue Pain Scale (VAS) (at rest, first in the morning, and with activities), the Foot and Ankle Ability Measure (FAAM), the Lower Extremity Functional Scale (LEFS), as well as the pressure pain threshold. [Results]The data indicated that both dry cupping therapy and electrical stimulation therapy could reduce pain and increase function significantly in the population tested, as all the 95% Confidence Intervals (CIs) did not include 0 except for the pressure pain threshold. There was no significant difference between the dry cupping therapy and electrical stimulation groups in all the outcome measurements. [Conclusion] These results support that both dry cupping therapy and electrical stimulation therapy could reduce pain and increase function in the population tested.

    Fibromyalgia is a common, chronic pain condition for which patients frequently use complementary and alternative medicine, including Reiki. Our objective was to determine whether Reiki is beneficial as an adjunctive fibromyalgia treatment. This was a factorial designed, randomized, sham-controlled trial in which participants, data collection staff, and data analysts were blinded to treatment group. The study setting was private medical offices in the Seattle, Washington metropolitan area. The subjects were comprised 100 adults with fibromyalgia. Four (4) groups received twice-weekly treatment for 8 weeks by either a Reiki master or actor randomized to use direct touch or no touch (distant therapy). The primary outcome was subjective pain as measured by visual analog scale at weeks 4, 8, and 20 (3 months following end of treatment). Secondary outcomes were physical and mental functioning, medication use, and health provider visits. Participant blinding and adverse effects were ascertained by self-report. Improvement between groups was examined in an intention-to-treat analysis. Neither Reiki nor touch had any effect on pain or any of the secondary outcomes. All outcome measures were nearly identical among the 4 treatment groups during the course of the trial. Neither Reiki nor touch improved the symptoms of fibromyalgia. Energy medicine modalities such as Reiki should be rigorously studied before being recommended to patients with chronic pain symptoms.

    Flexible nasolaryngoscopy is an essential skill for otolaryngology trainees to develop, but there is a lack of standardized training for this procedure. The aim of this study was to assess whether using training on a realistic human mannequin together with structured video feedback improved trainees' performance at flexible nasolaryngoscopy. Three-armed, single-blinded, randomized controlled study. Thirty-six junior doctors and final-year medical students were randomly allocated to one of three groups. All received a lecture and video presentation on flexible nasolaryngoscopy. One group received additional tuition using a training mannequin. The last group received mannequin training and feedback on their performance using a video recording. The trainees then undertook flexible nasolaryngoscopy on volunteers with these endoscopies recorded. Blinded observers scored the trainees on a range of objective and subjective measures. The volunteers who were also blinded to the candidates' training scored the comfort of the procedure. Adding mannequin training showed a trend toward improvement of performance but did not reach statistical significance. Mannequin training together with video feedback produced significant performance improvement in patient comfort (P = .0065), time to reach the vocal folds (P = .017), and global ability (P = .0006). Inter-rater reliability was excellent with P training using an anatomically correct model of the upper airway together with formalized video-assisted feedback on that training is a simple and effective way to improve endoscopy skills prior to starting flexible nasolaryngoscopy on patients. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    This controlled randomized single-blind study evaluated the effects of cognitive training (CT), compared to active music therapy (AMT) and neuroeducation (NE), on initiative in patients with mild to moderate Alzheimer's disease (AD). Secondarily, we explored the effects of CT on episodic memory, mood, and social relationships. Thirty-nine AD patients were randomly assigned to CT, AMT, or NE. Each treatment lasted 3 months. Before, at the end, and 3 months after treatment, neuropsychological tests and self-rated scales assessed initiative, episodic memory, depression, anxiety, and social relationships. At the end of the CT, initiative significantly improved, whereas, at the end of AMT and NE, it was unchanged. Episodic memory showed no changes at the end of CT or AMT and a worsening after NE. The rates of the patients with clinically significant improvement of initiative were greater after CT (about 62%) than after AMT (about 8%) or NE (none). At the 3-month follow-up, initiative and episodic memory declined in all patients. Mood and social relationships improved in the three groups, with greater changes after AMT or NE. In patients with mild to moderate AD, CT can improve initiative and stabilize memory, while the non-cognitive treatments can ameliorate the psychosocial aspects. The combining of CT and non-cognitive treatments may have useful clinical implications.

    Full Text Available Hip fracture commonly results in considerable consequences in terms of disability, mortality, long-term institutional care and cost. Taiwan launched its universal health insurance coverage in 1995, which largely removes financial barriers to health care. This study aims to investigate whether socioeconomic inequality in one-year mortality exists among Taiwanese elderly people. This population-based cohort study included 193,158 elderly patients (≥65 years admitted for hip fracture between 2000 and 2012. With over a one-year follow-up, 10.52% of the participants died from all causes. The mortality rate was low in the northern part of Taiwan and in urban and high-family-income areas. Multiple Poisson regression models further suggested that the level of >Q1–Q3 and >Q3–Max showed significantly reduced odds ratio of one-year mortality at 0.90 (95% confidence interval (CI, 0.87–0.93 and 0.77 (95% CI, 0.74–0.81, respectively, compared with that of the lowest family income level (i.e., Min.–Q1. Despite a monotonic decline in overall one-year mortality during the study period, socioeconomic inequality in one-year mortality rate remained evident. The annual percentage change in one-year mortality was higher (−2.86 in elderly people from families with high income (>Q3–Max. than that for elderly patients from family with low income (Min.–Q1, −1.94. Accessibility, rather than affordability, to health care for hip fracture is probably responsible for the observed socioeconomic inequality.

    Each year we attempt to contact each person who received a bachelor's degree in physics one year earlier to ask them what they are doing. New degree recipients typically follow one of two paths: enrolling in graduate school or entering the employment market. For the classes of 2011 and 2012 combined, nearly 60% chose to enroll in a graduate program; almost 40% of those opting for graduate school went into a field other than physics or astronomy. Only 4% of physics bachelor's degree recipients from the classes of 2011 and 2012 were still seeking employment one year after graduation.

    Negative emotions can cause a number of prenatal problems and disturb obstetric outcomes. We determined the effectiveness of prenatal emotional management on obstetric outcomes in nulliparas. All participants completed the PHQ-9 at the baseline assessment. Then, the participants were randomly assigned to the emotional management (EM) and usual care (UC) groups. The baseline evaluation began at 31 weeks gestation and the participants were followed up to 42 days postpartum. Each subject in the EM group received an extra EM program while the participants in the UC groups received routine prenatal care and education only. The PHQ-9 and Edinburgh Postnatal Depression scale (EPDS) were used for assessment. The EM group had a lower PHQ-9 score at 36 weeks gestation, and 7 and 42 days after delivery (P Prenatal EM intervention could control anxiety and depressive feelings in nulliparas, and improve obstetric outcomes. It may serve as an innovative approach to reduce the cesarean section rate in China.

    Randomized, double-blind, placebo-controlled clinical trials are currently the best way to demonstrate the clinical effectiveness of drugs. Its methodology relies on the method of difference (John Stuart Mill), through which the observed difference between two groups (drug vs placebo) can be attributed to the pharmacological effect of the drug being tested. However, this additive model can be questioned in the event of statistical interactions between the pharmacological and the placebo effects. Evidence in different domains has shown that the placebo effect can influence the effect of the active principle. This article evaluates the methodological, clinical and epistemological consequences of this phenomenon. Topics treated include extrapolating results, accounting for heterogeneous results, demonstrating the existence of several factors in the placebo effect, the necessity to take these factors into account for given symptoms or pathologies, as well as the problem of the "specific" effect.

    Randomized controlled trials (RCTs) of interventions intended to modify health behaviors may be influenced by neighborhood effects which can impede unbiased estimation of intervention effects. Examining a RCT designed to increase colorectal cancer (CRC) screening (N=5628), we found statistically significant neighborhood effects: average CRC test use among neighboring study participants was significantly and positively associated with individual patient's CRC test use. This potentially important spatially-varying covariate has not previously been considered in a RCT. Our results suggest that future RCTs of health behavior interventions should assess potential social interactions between participants, which may cause intervention arm contamination and may bias effect size estimation.

    1988-01-01

    The authors review 100 randomized controlled trials (RCTs) that examine the safety or efficacy of new low-osmolality contrast media (LOM) and focus on the 43 RCTs judged to be of the highest quality. These RCTs showed no consistent differences in nephrotoxicity between high- and low-osmolality contrast media. Certain cardiovascular parameters were altered less with low-osmolality agents during intracardiac injection, but the clinical significance of these differences in unclear. Heat and pain sensations occurred less often with low-osmolality contrast media. No differences were noted in the incidence of nausea, vomiting, urticaria, or bronchospasm. Even with numerous RCTs comparing these media, physicians still must make economically significant choices about contrast media without sufficient data about their relative safety

    There is evidence that Mediterranean diets with a high proportion of olive oil and nuts can be effective for weight management and prevention of cardiovascular disease. It might be difficult for populations with other eating habits to follow such diets. Therefore, a modified Mediterranean-type diet using fat modification through neutral and butter-flavored canola oil, walnuts and walnut oil with two portion-controlled sweet daily snacks was tested in Germany. Randomized waiting-list control study with overweight/grade 1 obese subjects: 12-week self-help modified Mediterranean-type diet, 6 weeks of diet plans and 6 weeks of weight loss maintenance training. Trial duration was 12 months. Intervention group (IG) included 100 participants (average age of 52.4 years, weight 85.1 kg and body mass index (BMI) 30.1 kg/m(2)), waiting-list control group (CG) included 112 participants (52.6 years, 84.1 kg and 30.1 kg/m(2)). Per-protocol weight loss after 12 weeks was 5.2 kg in IG vs 0.4 kg in CG (P ⩽ 0.0001), BMI -1.8 vs -0.1 kg/m(2) (P ⩽ 0.0001), waist circumference -4.7 vs -0.9 cm (P ⩽ 0.0001). Triglycerides, total cholesterol and LDL cholesterol improved significantly in IG but not in CG. One-year dropouts: 44% in IG and 53% in CG. Weight loss after 12 months: 4.2 kg (pooled data). A five-meal modified Mediterranean-type diet with two daily portion-controlled sweet snacks was effective for weight management in a self-help setting for overweight and grade 1 obese subjects. Fat modification through canola oil, walnuts and walnut oil improved blood lipids even at 12 months.

    Working in crisis environments represents a major challenge, especially for executive personnel engaged in directing disaster operations, i.e. crisis managers. Crisis management involves operating under conditions of extreme stress resulting, for instance, from high-level decision-making, principal responsibility for personnel, multitasking or working under conditions of risk and time pressure. The present study aimed to investigate the efficacy of a newly developed biofeedback training procedure based on electrodermal activity, especially designed for the target group of crisis managers. The training comprised exercises promoting acquisition of control over sympathetic arousal under resting conditions and during exposure to visual, acoustic and cognitive stressors resembling situations related to crisis management. In a randomized controlled design, 36 crisis managers were assigned to either a biofeedback training group or waiting list control group. Subjective stress was assessed using the Perceived Stress Scale. In the training group, stress level markedly decreased; the decrease remained stable at follow-up 2 months after the training. The results indicate that biofeedback training in crisis management is an effective method for stress management that may help to reduce vulnerability to stress-related performance decline and stress-related disease.

    Full Text Available Introduction. Qigong is currently considered as meditative movement, mindful exercise, or complementary exercise and is being explored for relief of symptoms in fibromyalgia. Aim. This narrative review summarizes randomized controlled trials, as well as additional studies, of qigong published to the end of 2013 and discusses relevant methodological issues. Results. Controlled trials indicate regular qigong practice (daily, 6–8 weeks produces improvements in core domains for fibromyalgia (pain, sleep, impact, and physical and mental function that are maintained at 4–6 months compared to wait-list subjects or baselines. Comparisons with active controls show little difference, but compared to baseline there are significant and comparable effects in both groups. Open-label studies provide information that supports benefit but remain exploratory. An extension trial and case studies involving extended practice (daily, 6–12 months indicate marked benefits but are limited by the number of participants. Benefit appears to be related to amount of practice. Conclusions. There is considerable potential for qigong to be a useful complementary practice for the management of fibromyalgia. However, there are unique methodological challenges, and exploration of its clinical potential will need to focus on pragmatic issues and consider a spectrum of trial designs. Mechanistic considerations need to consider both system-wide and more specific effects.

    Random number generation (RNG) is a functionally complex process that is highly controlled and therefore dependent on Baddeley's central executive. This study addresses this issue by investigating whether key predictions from this framework are compatible with empirical data. In Experiment 1, the effect of increasing task demands by increasing the rate of the paced generation was comprehensively examined. As expected, faster rates affected performance negatively because central resources were increasingly depleted. Next, the effects of participants' exposure were manipulated in Experiment 2 by providing increasing amounts of practice on the task. There was no improvement over 10 practice trials, suggesting that the high level of strategic control required by the task was constant and not amenable to any automatization gain with repeated exposure. Together, the results demonstrate that RNG performance is a highly controlled and demanding process sensitive to additional demands on central resources (Experiment 1) and is unaffected by repeated performance or practice (Experiment 2). These features render the easily administered RNG task an ideal and robust index of executive function that is highly suitable for repeated clinical use. ((c) 2006 APA, all rights reserved).

    Multiple reports illustrate the deleterious effects of stress on physicians' mental and physical health, as well as on patient care. This study evaluates the effects of a wellness program on anesthesiology residents' well-being. Sixty residents were randomly assigned to one of three groups: (1) wellness intervention group, (2) no-treatment control with release time, and (3) no-treatment control with routine duties. Coping, stressors, social support, psychological symptoms, and alcohol and tobacco use were measured using a pre-test-post-test design. Residents in the wellness program reported significantly fewer stressors in their role as parent, increased social support at work, greater problem-solving coping, and less anxiety as compared with one or both of the control groups. Findings related to reducing avoidance coping and alcohol consumption also were suggestive of positive intervention effects. An intervention to increase the use of active coping and social support, to reduce reliance on avoidance coping, and to decrease work and family stressors had an overall pattern of beneficial effects on residents' well-being. The importance of offering such programs during residency training, ways to strengthen intervention effectiveness, and areas for future research are discussed. © 2012 The Authors.

    It is not established whether behavioral interventions add benefit to pharmacological therapy for hypertension. We hypothesized that behavioral neurocardiac training (BNT) with heart rate variability biofeedback would reduce blood pressure further by modifying vagal heart rate modulation during reactivity and recovery from standardized cognitive tasks ("mental stress"). This randomized, controlled trial enrolled 65 patients with uncomplicated hypertension to BNT or active control (autogenic relaxation), with six 1-hour sessions over 2 months with home practice. Outcomes were analyzed with linear mixed models that adjusted for antihypertensive drugs. BNT reduced daytime and 24-hour systolic blood pressures (-2.4+/-0.9 mm Hg, P=0.009, and -2.1+/-0.9 mm Hg, P=0.03, respectively) and pulse pressures (-1.7+/-0.6 mm Hg, P=0.004, and -1.4+/-0.6 mm Hg, P=0.02, respectively). No effect was observed for controls (P>0.10 for all indices). BNT also increased RR-high-frequency power (0.15 to 0.40 Hz; P=0.01) and RR interval (P0.10). In contrast to relaxation therapy, BNT with heart rate variability biofeedback modestly lowers ambulatory blood pressure during wakefulness, and it augments tonic vagal heart rate modulation. It is unknown whether efficacy of this treatment can be improved with biofeedback of baroreflex gain. BNT, alone or as an adjunct to drug therapy, may represent a promising new intervention for hypertension.

    OBJECTIVE: To determine the effects of acetaminophen and axillary temperature responses on infant sleep duration after immunization. METHODS: We conducted a prospective, randomized controlled trial to compare the sleep of 70 infants monitored by using ankle actigraphy for 24 hours before and after their first immunization series at ∼2 months of age. Mothers of infants in the control group received standard care instructions from their infants' health care provider, and mothers of infants in the intervention group were provided with predosed acetaminophen and instructed to administer a dose 30 minutes before the scheduled immunization and every 4 hours thereafter, for a total of 5 doses. Infant age and birth weight and immunization factors, such as acetaminophen use and timing of administration, were evaluated for changes in infant sleep times after immunization. RESULTS: Sleep duration in the first 24 hours after immunization was increased, particularly for infants who received their immunizations after 1:30 pm and for those who experienced elevated temperatures in response to the vaccines. Infants who received acetaminophen at or after immunization had smaller increases in sleep duration than did infants who did not. However, acetaminophen use was not a significant predictor of sleep duration when other factors were controlled. CONCLUSIONS: If further research confirms the relationship between time of day of vaccine administration, increased sleep duration after immunization, and antibody responses, then our findings suggest that afternoon immunizations should be recommended to facilitate increased sleep in the 24 hours after immunization, regardless of acetaminophen administration.

    To evaluate the short-term efficacy of acupuncture for the treatment of peri-menopausal insomnia (PMI). Design: A randomized, participant-blind, placebo-controlled trial consisted of the acupuncture group (n = 38) and placebo-acupuncture group (n = 38). Setting: A tertiary teaching and general hospital. Participants: 76 peri-menopausal women with insomnia disorder based on the International Classification of Sleep Disorders, Third Edition. Interventions: A 10-session of acupuncture at bilateral Shenshu (BL 23) and Ganshu (BL 18) with unilateral Qimen (LR 14) and Jingmen (GB 25) or Streitberger needles at the same acupoints was performed for over 3 weeks. Measurements: Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) with over-night polysomnography (PSG) exam were completed at baseline and post-treatment. After the treatments, the decrease from baseline in PSQI score was 8.03 points in acupuncture group and 1.29 points in placebo-acupuncture group. The change from baseline in ISI score was 11.35 points in acupuncture group and 2.87 points in placebo-acupuncture group. In PSG data, acupuncture significantly improved the sleep efficiency and total sleep time, associated with less wake after sleep onset and lower percent stage 1 after the treatment. No significant differences from baseline to post-treatment were found in placebo-acupuncture group. Acupuncture can contribute to a clinically relevant improvement in the short-term treatment of PMI, both subjectively and objectively.

    Full Text Available BACKGROUND: With the increasing prevalence of chronic noncommunicable diseases, patient education is becoming important to strengthen disease prevention and control. We aimed to systematically determine the extent to which registered, ongoing randomized controlled trials (RCTs evaluated an educational intervention focus on patient-important outcomes (i.e., outcomes measuring patient health status and quality of life. METHODS: On May 6, 2009, we searched for all ongoing RCTs registered in the World Health Organization International Clinical Trials Registry platform. We used a standardized data extraction form to collect data and determined whether the outcomes assessed were 1 patient-important outcomes such as clinical events, functional status, pain, or quality of life or 2 surrogate outcomes, such as biological outcome, treatment adherence, or patient knowledge. PRINCIPAL FINDINGS: We selected 268 of the 642 potentially eligible studies and assessed a random sample of 150. Patient-important outcomes represented 54% (178 of 333 of all primary outcomes and 46% (286 of 623 of all secondary outcomes. Overall, 69% of trials (104 of 150 used at least one patient-important outcome as a primary outcome and 66% (99 of 150 as a secondary outcome. Finally, for 31% of trials (46 of 150, primary outcomes were only surrogate outcomes. The results varied by medical area. In neuropsychiatric disorders, patient important outcomes represented 84% (51 of 61 of primary outcomes, as compared with 54% (32 of 59 in malignant neoplasm and 18% (4 of 22 in diabetes mellitus trials. In addition, only 35% assessed the long-term impact of interventions (i.e., >6 months. CONCLUSIONS: There is a need to improve the relevance of outcomes and to assess the long term impact of educational interventions in RCTs.

    Hockey Fans in Training (Hockey FIT) is a gender-sensitized weight loss and healthy lifestyle program. We investigated 1) feasibility of recruiting and retaining overweight and obese men into a pilot pragmatic randomized controlled trial and 2) potential for Hockey FIT to lead to weight loss and improvements in other outcomes at 12 wk and 12 months. Male fans of two ice hockey teams (35-65 yr; body mass index ≥28 kg·m) located in Ontario (Canada) were randomized to intervention (Hockey FIT) or comparator (wait-list control). Hockey FIT includes a 12-wk active phase (weekly, coach-led group meetings including provision of dietary information, practice of behavior change techniques, and safe exercise sessions plus incremental pedometer walking) and a 40-wk minimally supported phase (smartphone app for sustaining physical activity, private online social network, standardized e-mails, booster session/reunion). Measurement at baseline and 12 wk (both groups) and 12 months (intervention group only) included clinical outcomes (e.g., weight) and self-reported physical activity, diet, and self-rated health. Eighty men were recruited in 4 wk; trial retention was >80% at 12 wk and >75% at 12 months. At 12 wk, the intervention group lost 3.6 kg (95% confidence interval, -5.26 to -1.90 kg) more than the comparator group (P < 0.001) and maintained this weight loss to 12 months. The intervention group also demonstrated greater improvements in other clinical measures, physical activity, diet, and self-rated health at 12 wk; most sustained to 12 months. Results suggest feasible recruitment/retention of overweight and obese men in the Hockey FIT program. Results provide evidence for the potential effectiveness of Hockey FIT for weight loss and improved health in at-risk men and, thus, evidence to proceed with a definitive trial.

    2010-01-01

    The literature on psychosocial job factors and musculoskeletal pain is inconclusive in part due to insufficient control for confounding by biomechanical factors. The aim of this study was to investigate prospectively the independent effects of effort-reward imbalance (ERI) at work on regional musculoskeletal pain of the neck and upper extremities of call center operators after controlling for (i) duration of computer use both at work and at home, (ii) ergonomic workstation design, (iii) physical activities during leisure time, and (iv) other individual worker characteristics. This was a one-year prospective study among 165 call center operators who participated in a randomized ergonomic intervention trial that has been described previously. Over an approximate four-week period, we measured ERI and 28 potential confounders via a questionnaire at baseline. Regional upper-body pain and computer use was measured by weekly surveys for up to 12 months following the implementation of ergonomic interventions. Regional pain change scores were calculated as the difference between average weekly pain scores pre- and post intervention. A significant relationship was found between high average ERI ratios and one-year increases in right upper-extremity pain after adjustment for pre-intervention regional mean pain score, current and past physical workload, ergonomic workstation design, and anthropometric, sociodemographic, and behavioral risk factors. No significant associations were found with change in neck-shoulder or left upper-extremity pain. This study suggests that ERI predicts regional upper-extremity pain in -computer operators working >or=20 hours per week. Control for physical workload and ergonomic workstation design was essential for identifying ERI as a risk factor.

    Stroke is one of the most common causes of death and few pharmacological therapies show benefits in ischemic stroke. In this study, 290 patients aged 40-75 years old with first onset of acute ischemic stroke (more than 24 hours but within 14 days) were treated with standard treatments, and then were randomly allocated into an intervention group (treated with resuscitating acupuncture) and a control group (treated using sham-acupoints). Primary outcome measures included Barthel Index (BI), relapse and death up to six months. For the 290 patients in both groups, one case in the intervention group died, and two cases in the control group died from the disease (p = 0.558). Six patients of the 144 cases in the intervention group had relapse, whereas 34 of 143 patients had relapse in the control group (p two groups, respectively (p two groups for the National Institute of Health Stroke Scale (NIHSS), not at two weeks (7.03 ± 3.201 vs. 8.13 ± 3.634; p = 0.067), but at four weeks (4.15 ± 2.032 vs. 6.35 ± 3.131, p Stroke Scale (CSS) at four weeks showed more improvement in the intervention group than that in the control group (9.40 ± 4.51 vs. 13.09 ± 5.80, p Stroke Specific Quality of Life Scale (SS-QOL) at six months was higher in the intervention group (166.63 ± 45.70) than the control group (143.60 ± 50.24; p < 0.01). The results of this clinical trial showed a clinically relevant decrease of relapse in patients treated with resuscitating acupuncture intervention by the end of six months, compared with needling at the sham-acupoints. The resuscitating acupuncture intervention could also improve self-care ability and quality of life, evaluated with BI, NIHSS, CSS, Oxford Handicap Scale (OHS), and SS-QOL.

    Full Text Available Abstract Background A central tenet in developmental psychopathology is that childhood rearing experiences have a major impact on children’s development. Recently, candidate genes have been identified that may cause children to be differentially susceptible to these experiences (i.e., susceptibility genes. However, our understanding of the differential impact of parenting is limited at best. Specifically, more experimental research is needed. The ORCHIDS study will investigate gene-(gene-environment interactions to obtain more insight into a moderating effects of polymorphisms on the link between parenting and child behavior, and b behavioral mechanisms that underlie these gene-(gene-environment interactions in an experimental design. Methods/Design The ORCHIDS study is a randomized controlled trial, in which the environment will be manipulated with an intervention (i.e., Incredible Years parent training. In a screening, families with children aged 4–8 who show mild to (subclinical behavior problems will be targeted through community records via two Dutch regional healthcare organizations. Assessments in both the intervention and control condition will be conducted at baseline (i.e., pretest, after 6 months (i.e., posttest, and after 10 months (i.e., follow-up. Discussion This study protocol describes the design of a randomized controlled trial that investigates gene-(gene-environment interactions in the development of child behavior. Two hypotheses will be tested. First, we expect that children in the intervention condition who carry one or more susceptibility genes will show significantly lower levels of problem behavior and higher levels of prosocial behavior after their parent(s received the Incredible Years training, compared to children without these genes, or children in the control group. Second, we expect that children carrying one or more susceptibility genes will show a heightened sensitivity to changes in parenting behaviors, and

Patients and Methods: From September 2009 to March 2012, primary PCI was performed on 70 cases, and the data relating to their catheterization were recorded. Peri-interventional treatment data included PCI with drug-eluting or bare-metal stent or balloon angioplasty alone. Results: The mean age of the patients was 61.34+11.31 years, and 72.9% of them were males. The ratios of patients with diabetes, hypertension and, hyperlipidemia were 61.4%, 71.4%, and 52.9% respectively. In clinical follow-up, total incidence of death was 4.3%, with no death occurring during 30 days. However, 3 patients died after one-year, of which one patient (1.4% had cardiac problem and the other 2 (2.9% died because of non-cardiac reasons. Target vessel revascularization, reinfarction within 30 days, and mechanical complication or stroke were not found in any of the patients. Patients with hypertension (6% and those with LAD ST-elevation myocardial infarction (5% died after one year (P= 0.263 and P= 0.319 respectively. However, no mortality was reported in patients with RCA and LCX ST-elevation myocardial infarction. Of subjects with multivessel disease, 7% died after one-year (P= 0.161, but there was no reported mortality in those with single vessel disease.

    While benefits of workplace physical exercise on physical health is well known, little is known about the psychosocial effects of such initiatives. This study evaluates the effect of workplace versus home-based physical exercise on psychosocial factors among healthcare workers. A total of 200 female healthcare workers (Age: 42.0, BMI: 24.1) from 18 departments at three hospitals were cluster-randomized to 10 weeks of: 1) home-based physical exercise (HOME) performed alone during leisure time for 10 min 5 days per week or 2) workplace physical exercise (WORK) performed in groups during working hours for 10 min 5 days per week and up to 5 group-based coaching sessions on motivation for regular physical exercise. Vitality and mental health (SF-36, scale 0-100), psychosocial work environment (COPSOQ, scale 0-100), work- and leisure disability (DASH, 0-100), control- (Bournemouth, scale 0-10) and concern about pain (Pain Catastrophizing Scale, scale 0-10) were assessed at baseline and at 10-week follow-up. Vitality as well as control and concern about pain improved more following WORK than HOME (all p health remained unchanged. Between-group differences at follow-up (WORK vs. HOME) were 7 [95% confidence interval (95% CI) 3 to 10] for vitality, -0.8 [95% CI -1.3 to -0.3] for control of pain and -0.9 [95% CI -1.4 to -0.5] for concern about pain, respectively. Performing physical exercise together with colleagues during working hours was more effective than home-based exercise in improving vitality and concern and control of pain among healthcare workers. These benefits occurred in spite of increased work pace. NCT01921764 at ClinicalTrials.gov . Registered 10 August 2013.

    To test whether an eczema care plan (ECP) would improve provider documentation and management, decrease eczema severity, and increase patient quality of life (QOL) in the pediatric primary care setting. We conducted a randomized controlled trial from June 2015 to September 2016 at a large hospital-based pediatric primary care clinic. Participants included children from 1 month to 16 years of age with a diagnosis of eczema. The intervention group received the ECP and the control group received usual care. Both groups completed a validated eczema severity scale (Patient-Oriented Eczema Measure [POEM]) and a QOL scale (Infant's Dermatitis Quality of Life Index [IDQOL]) or Children's Dermatology Life Quality Index [CDLQI]) before the visit and again ~1 month later. A total of 211 caregivers completed both the pre- and postintervention surveys (100 control group and 111 intervention group [94% completion]). Intervention group providers were more likely to recommend a comprehensive "step-up" plan (88%) vs 28%; P plan to families (80%) vs 2%; P improved between the pre- and postintervention periods. However, there was not a significant difference between the groups on either measure: POEM difference -0.8, 95% confidence interval (CI) -3.2 to 1.7; IDQOL difference -0.1, 95% CI -1.8 to 1.6; CDLQI difference 0.8, 95% CI -0.9 to 2.6. Intervention group providers documented more comprehensive eczema care than control group providers. Although patients improved on all measures in the postintervention period, the ECP did not augment that improvement. Copyright © 2018 Academic Pediatric Association. Published by Elsevier Inc.

    Full Text Available Background/Aim. Acute heart failure (AHF is one of the most common diseases in emergency medicine, associated with poor prognosis and high in-hospital and longterm mortality. The aim of this study was to investigate characteristics, outcomes and one year mortality of patients with AHF in the local population. Methods. This prospective study consisted of 64 consecutive unselected patients treated in the Coronary Care Unit of the Emergency Centre (Clinical Center of Serbia, Belgrade and were followed for one year after the discharge. Results. Mean age of the patients was 63.6 ± 12.6 years and 59.4% were males. Acute congestion (43.8% and pulmonary edema (39.1% were the most common presentations of AHF. Mean left ventricular ejection fraction (LVEF was 39.7% ± 9.25%, while 44.4% of the patients had LVEF ≥ 50%. At discharge, 55.9% of the patients received therapy with β-blockers, 94.9% diuretics, out of which 47.7% spironolactone, 94.9% patients were given ACE-inhibitors or angiotensin receptor blokcers (ARB. The 12-month all-cause mortality was 26.5%. Independent predictors of one year mortality were previous hospitalization due to heart disease, reduced LVEF, reduced fraction of shortening (FS and a higher tricuspid velocity. Conclusion. One year mortality of our patients with AHF was high, similar to the known European studies. Independent predictors of one year mortality were previous hospitalization due to heart disease, reduced LVEF and LVFS and a higher tricuspid velocity.

    Full Text Available To test the hypotheses that community-dwelling veterans with spinal cord injury (SCI who receive the Wheelchair Skills Training Program (WSTP in their own environments significantly improve their manual wheelchair-skills capacity, retain those improvements at one year and improve participation in comparison with an Educational Control (EC group.We carried out a randomized controlled trial, studying 106 veterans with SCI from three Veterans Affairs rehabilitation centers. Each participant received either five one-on-one WSTP or EC sessions 30-45 minutes in duration. The main outcome measures were the total and subtotal percentage capacity scores from the Wheelchair Skills Test 4.1 (WST and Craig Handicap Assessment and Reporting Technique (CHART scores.Participants in the WSTP group improved their total and Advanced-level WST scores by 7.1% and 30.1% relative to baseline (p < 0.001 and retained their scores at one year follow-up. The success rates for individual skills were consistent with the total and subtotal WST scores. The CHART Mobility sub-score improved by 3.2% over baseline (p = 0.021.Individualized wheelchair skills training in the home environment substantially improves the advanced and total wheelchair skills capacity of experienced community-dwelling veterans with SCI but has only a small impact on participation.

    Full Text Available AbstractThe rate of peak workload improvement between different types of Active Video Games (AVG in young sedentary adults was investigated. Aerobic capacity improvement after a 6-week intervention between AVG types was also compared. Twenty participants, after baseline assessments, were randomized into one of three parallel groups: structured AVG (n= 6, unstructured AVG (n= 7 and a control group (n= 7. Participants played their respective AVG 3 times a week for 6-weeks (30 minutes-session. The control group maintained normal activities. Both structured and unstructured AVG improved peak workload after four weeks but only the structured group maintained this improvement through week five and six. Aerobic capacity improved in the unstructured (Pre: 36.0 ± 5.2ml.kg.min-¹,Post: 39.7 ± 4.9ml.kg.min-¹, p = .038 and structured AVG (Pre: 39.0 ± 5.9ml.kg.min-¹,Post: 47.8 ± 4.3ml.kg.min-¹, p = .006 groups. Structured AVG provide greater health benefits to aerobic capacity and peak workload in young sedentary but otherwise healthy males relative to unstructured AVG.

    To study the clinical effectiveness of biofeedback treatment in reducing tics in patients with Tourette syndrome. Despite advances in the pharmacologic treatment of patients with Tourette syndrome, many remain troubled by their tics, which may be resistant to multiple medications at tolerable doses. Electrodermal biofeedback is a noninvasive biobehavioral intervention that can be useful in managing neuropsychiatric and neurologic conditions. We conducted a randomized controlled trial of electrodermal biofeedback training in 21 patients with Tourette syndrome. After training the patients for 3 sessions a week over 4 weeks, we observed a significant reduction in tic frequency and improved indices of subjective well-being in both the active-biofeedback and sham-feedback (control) groups, but there was no difference between the groups in these measurements. Furthermore, the active-treatment group did not demonstrably learn to reduce their sympathetic electrodermal tone using biofeedback. Our findings indicate that this form of biofeedback training was unable to produce a clinical effect greater than placebo. The main confounding factor appeared to be the 30-minute duration of the training sessions, which made it difficult for patients to sustain a reduction in sympathetic tone when their tics themselves were generating competing phasic electrodermal arousal responses. Despite a negative finding in this study, electrodermal biofeedback training may have a role in managing tics if optimal training schedules can be identified.

    Full Text Available Objective: The research determined the usage and satisfaction levels with one of two point-of-care (PoC resources among health care providers in a rural state. Methods: In this randomized controlled trial, twenty-eight health care providers in rural areas were stratified by occupation and region, then randomized into either the DynaMed or the AccessMedicine study arm. Study participants were physicians, physician assistants, and nurses. A pre- and post-study survey measured participants’ attitudes toward different information resources and their information-seeking activities. Medical student investigators provided training and technical support for participants. Data analyses consisted of analysis of variance (ANOVA, paired t tests, and Cohen’s d statistic to compare pre- and post-study effects sizes. Results: Participants in both the DynaMed and the AccessMedicine arms of the study reported increased satisfaction with their respective PoC resource, as expected. Participants in both arms also reported that they saved time in finding needed information. At baseline, both arms reported too little information available, which increased to ‘‘about right amounts of information’’ at the completion of the study. DynaMed users reported a Cohen’s d increase of þ1.50 compared to AccessMedicine users’ reported use of 0.82. DynaMed users reported d2 satisfaction increases of 9.48 versus AccessMedicine satisfaction increases of 0.59 using a Cohen’s d. Conclusion: Participants in the DynaMed arm of the study used this clinically oriented PoC more heavily than the users of the textbook-based AccessMedicine. In terms of user satisfaction, DynaMed users reported higher levels of satisfaction than the users of AccessMedicine.

    PURPOSE Knee osteoarthritis is a common, debilitating chronic disease. Prolotherapy is an injection therapy for chronic musculoskeletal pain. We conducted a 3-arm, blinded (injector, assessor, injection group participants), randomized controlled trial to assess the efficacy of prolotherapy for knee osteoarthritis. METHODS Ninety adults with at least 3 months of painful knee osteoarthritis were randomized to blinded injection (dextrose prolotherapy or saline) or at-home exercise. Extra- and intra-articular injections were done at 1, 5, and 9 weeks with as-needed additional treatments at weeks 13 and 17. Exercise participants received an exercise manual and in-person instruction. Outcome measures included a composite score on the Western Ontario McMaster University Osteoarthritis Index (WOMAC; 100 points); knee pain scale (KPS; individual knee), post-procedure opioid medication use, and participant satisfaction. Intention-to-treat analysis using analysis of variance was used. RESULTS No baseline differences existed between groups. All groups reported improved composite WOMAC scores compared with baseline status (P dextrose prolotherapy improved more (P <.05) at 52 weeks than did scores for patients receiving saline and exercise (score change: 15.3 ± 3.5 vs 7.6 ± 3.4, and 8.2 ± 3.3 points, respectively) and exceeded the WOMAC-based minimal clinically important difference. Individual knee pain scores also improved more in the prolotherapy group (P = .05). Use of prescribed postprocedure opioid medication resulted in rapid diminution of injection-related pain. Satisfaction with prolotherapy was high. There were no adverse events. CONCLUSIONS Prolotherapy resulted in clinically meaningful sustained improvement of pain, function, and stiffness scores for knee osteoarthritis compared with blinded saline injections and at-home exercises.

    More than 500 studies were conducted in Haiti following the January 12 of 2010 earthquake, yet few of them assessed mental health of the population. To our knowledge, none targeted the effectiveness of various methods used to treat survivors, whether adults or children Our study aimed to assess one year after the disaster, the effect of a specific psycho-social support offered to relocated children in Port-au-Prince compared with a control group. The two groups were homogeneous in the intensity of the peritraumatic distress they experienced. We were unable to show a significant difference between both in the average scores for PTSD, nor for depression, nor in three out of the four sub-scales of the Child Behavior Check-List. In case children, 68% and 40.9%, respectively, and 50% and 20.5% of the control group, reported severe levels of the symptoms of PTSD and depression. These surprising results can be explained by the absence of equivalence in the two groups from a socio-demographic point of view and because subjects were not randomly selected in the recruitment process. This study has not made it possible to indicate the effectiveness of a specific psycho-social support offered to children in the aftermath of the disaster. On the other hand, the sample illustrates the high prevalence (more than 50% for PTSD) of severe post-traumatic stress in this group of school-age children, one year after the earthquake. These results indicate that serious attention should be paid to the mental health aspects in reconstruction program for the country. Copyright © 2014 Elsevier B.V. All rights reserved.

    Objective. To assess the one-year effectiveness on weight loss of a 3-week balneotherapy program (BT). Method. A Zelen double consent randomised controlled trial to compare one-year BMI loss between a 3-week BT program versus usual care (UC) for overweight or obese patients (BMI: 27–35 kg/m2), associated or not with a dietary motivational interview (DMI) during the follow-up, using a 2 × 2 factorial design. Main analysis was a per protocol analysis comparing patients attending BT to patients managed by UC, matched on sex, overweight or obese status, DMI randomisation and a propensity score to attend BT or to be managed by UC. Results. From the 257 patients who completed the follow-up, 70 patients of each group could be matched. Mean BMI loss was 1.91 kg/m2 [95%CI: 1.46; 2.35] for the BT patients and 0.20 kg/m2 [−0.24; 0.64] for the UC patients (P < 0.001), corresponding to a significant BT benefit of 1.71 kg/m2 [1.08; 2.33]. There was no significant effect of DMI and no interaction with BT or UC. No adverse reaction was observed for patients attending BT. Conclusion. A 3-week BT program provided a significant one-year benefit over the usual GP dietary advice for overweight and obese patients. PMID:23346190

    This study compared healing rates, relief of symptoms, frequency of adverse events, and proportion of patients in remission after one year follow up in 104 patients with active prepyloric ulcer during treatment with 40 mg omeprazole once daily or 2 g sucralfate twice daily, using a randomised double blind controlled trial. Healing rates after two, four, and six weeks were (omeprazole/sucralfate) 49%/23%; 83%/59%; 90%/70% respectively. After two weeks, omeprazole was more efficient than sucralfate in relief of daytime and nocturnal epigastric pain, nausea, and heartburn. The proportion of patients in remission after one year follow up was significantly higher in the omeprazole group (p < 0.01). Of the healed patients ulcers recurred in 36% in the omeprazole group and in 46% in the sucralfate group. It is concluded that the ulcer healing rate was higher and symptom relief was more pronounced in the omeprazole group compared with the sucralfate group, and that more patients were still in remission after a one year follow up period.

    Full Text Available Sickness absence from work due to experienced distress and mental health issues has continuously increased over the past years in Germany. To investigate how this alarming development can be counteracted, we conducted a randomized controlled trial evaluating a job coaching intervention to maintain the working capacity of members of staff and ultimately prevent sickness absence. Our sample included N = 99 employees who reported mental distress due to work-related problems. The intervention group (n = 58 received between 8 and 12 individual job coaching sessions in which they worked with a professional job coach to reduce their mental distress. The control group (n = 41 received a brochure about mental distress. Data were collected before the start of the study, at the end of the job coaching intervention and at a 3-month follow up. These data included the number of sickness absence days as the primary outcome and questionnaire measures to assess burnout indicators, life satisfaction and work-related experiences and behaviors. Compared with the control group, the results indicated no reduction in sickness absence in the intervention group but fewer depressive symptoms, a heightened ability of the participants to distance themselves from work, more experience of work-related success, less depletion of emotional resources and a greater satisfaction with life when participants had received the job coaching. Thus, although we could not detect a reduction in sickness absence between the groups, job coaching was shown to be a viable intervention technique to benefit employees by contributing to re-establish their mental health. We discuss the implications of the study and outline future research.

Pregnant women identified by history to be at risk (n=3,737) were examined for periodontal disease. Approximately 1,000 women with periodontal disease were allocated at random to receive periodontal treatment commencing around 20 weeks of gestation (n=542) or 6 weeks after the pregnancy was completed (controls; n=540). The treatment included mechanical removal of oral biofilms together with oral hygiene instruction and motivation at a minimum of three weekly visits, with further visits if required. There were no differences between the control and treatment groups in preterm birth (9.3% compared with 9.7%, odds ratio [OR] 1.05, 95% confidence interval [CI 0.7-1.58], P=.81), birth weight (3,450 compared with 3,410 g, P=.12), preeclampsia (4.1% compared with 3.4%, OR 0.82, 95% CI 0.44-1.56, P=.55), or other obstetric endpoints. There were four unexplained stillbirths in the control group and no pregnancy losses in the treated group (P=.12). Measures of fetal and neonatal well-being were similar in the two groups, including abnormalities in fetal heart rate recordings (P=.26), umbilical artery flow studies (P=.96), and umbilical artery blood gas values (P=.37). The periodontal treatment was highly successful in improving health of the gums (Pperiodontal disease during pregnancy in this population prevents preterm birth, fetal growth restriction, or preeclampsia.

    Background and Purpose Previous research has reported worse outcomes after stroke for women and for African Americans, but few prospective, population-based studies have systematically examined demographic differences on long-term stroke outcomes. Race and gender differences on one-year stroke outcomes were examined using an epidemiologically-derived sample of first-time stroke survivors from the national REasons for Geographic and Racial Differences in Stroke (REGARDS) study. Methods Participants of REGARDS who reported a first-time stroke event during regular surveillance calls were interviewed by telephone and then completed an in-home evaluation approximately one year after the verified first-time stroke event (N = 112). A primary family caregiver was also enrolled and interviewed for each stroke survivor. Measures from the in-home evaluation included previously validated stroke outcomes assessments of neurological deficits, functional impairments, and patient-reported effects of stroke in multiple domains. Results African American stroke survivors were less likely to be living with their primary family caregivers than White participants. Analyses that controlled for age, education, and whether the stroke survivors lived with their primary family caregivers indicated that African Americans and women showed significantly greater deficits on multiple one-year outcome measures compared to Whites and men, respectively. Conclusions Among community-dwelling stroke survivors with family caregivers, women and African Americans are at heightened risk for poor long-term outcomes one year after first-time stroke events. Rehabilitation services and public health policies aimed at enhancing stroke recovery rates should address these disparities in post-stroke outcomes. PMID:21257820

Control endoscopy showed the peptic ulcer had healed in 71/ 80 patients (88.8% from the study group and in 68/80 patients (85% from the control group (p > 0.05. Endoscopic investigation performed one year after inclusion in the study revealed a recurrence of Helicobacter pylori infection in 4 patients (5%, 4/80 from the study group and in 5 (6.3%, 5/80 from the control group (p > 0.05. Of these 9 patients we found peptic ulcer recurrence in only one patient (1.3%, 1/80 from the study group and in one (1.3%, 1/80 from the control group. Both patients has used preparations of acetylsalycilic acid prior to endoscopic investigation.Conclusions. The findings of our study confirm that during the observed period of time, one year, the reinfection rate with Helicobacter pylori was 5.6%. In this period we did not observed rebleeding due to peptic ulcer and only two patients had a recurrence of ulcer disease.

    Full Text Available Introduction: The survival of an implant system is affected by the choice of antirotational design, which can include an external or internal hex. Implant success also is affected by the maintenance of the crestal bone around implants. The aim of present study was to evaluate the crestal bone loss and clinical parameters related to bone loss in patients loaded with an external or internal hex 3i implant (3i Implant Innovation, Palm Beach Gardens, FL, USA. The evaluations were performed one year after loading. Materials and Methods: A total of 39 implants (23 external hex, 16 internal hex were placed randomly in 23 patients (10 male, 13 female by a submerged approach. None of patients had compromised conditions or parafunctional habits. At placement and at one year after loading, periapical radiographs were taken via the parallel method from the implant sites. Results: Crestal bone loss was -0.712±0.831 mm in implants with an internal hex connection and -0.139±0.505 mm in implants with an external hex connection (P≤0.05. No correlation was found between crestal bone loss and parameters such as age, gender, jaw, implant location (anterior, premolar, or molar, implant diameter, or implant length. Conclusions: Crestal bone loss was greater in patients with internal hex 3i implants than in those with external implants. Similar results in other clinical factors were found between the groups.

  11. Schizophrenia and quality of life: a one-year follow-up in four EU countries.

    LENUS (Irish Health Repository)

    2006-01-01

    BACKGROUND: This article systematically monitors the quality of life (QOL) of patients with schizophrenia from seven different sites across four European countries: France, Ireland, Portugal and Spain. METHODS: A one-year prospective cohort study was carried out. Inclusion criteria for patients were: a clinical lifetime diagnosis of schizophrenia according to ICD-10 (F20) diagnostic criteria for research, age between 18 and 65 years and at least one contact with mental health services in 1993. Data concerning QOL were recorded in seven sites from four countries: France, Portugal, Ireland and Spain, and were obtained using the Baker and Intagliata scale. At baseline, 339 patients answered the QOL questionnaire. At one-year follow-up, Spain could not participate, so only 263 patients were contacted and 219 agreed to take part. QOL was compared across centres by areas and according to a global index. QOL was correlated with presence of clinical and social problems, needs for care and interventions provided during the one-year follow-up. RESULTS: We did not find any link between gender and QOL. There were some significant differences between centres concerning many items. What is more, these differences were relative: in Lisbon where the lowest level of satisfaction was recorded, people were satisfied with food but highly dissatisfied with finances, whereas in St Etienne, where the highest level of satisfaction was recorded, people were less satisfied with food when they were more satisfied with finances. The evolution in one year among those respondents who took part in the follow-up (excluding the subjects from Granada) showed different patterns depending on the items. CONCLUSION: The four countries have different resources and patients live in rather different conditions. However, the main differences as far as their QOL is concerned very much depend on extra-psychiatric variables, principally marital status and income.

    Amoeba-resisting microorganisms raised a great interest during the last decade. Among them, some large DNA viruses present huge genomes up to 2.5 Mb long, exceeding the size of small bacterial genomes. The rate of genome evolution in terms of mutation, deletion, and gene acquisition in these genomes is yet unknown. Given the suspected high plasticity of viral genomes, the microevolution of the 346 kb genome of Lausannevirus, a member of Megavirales, was studied. Hence, Lausannevirus was co-cultured within the amoeba Acanthamoeba castellanii over one year. Despite a low number of mutations, the virus showed a genome reduction of 3.7% after 12 months. Lausannevirus genome evolution in sympatric conditions was investigated by its co-culture with Estrella lausannensis, an obligate intracellular bacterium, in the amoeba A. castellanii during one year. Cultures were split every 3 months. Genome sequencing revealed that in these conditions both, Lausannevirus and E. lausannensis, show stable genome, presenting no major rearrangement. In fact, after one year they acquired from 2 to 7 and from 4 to 10 mutations per culture for Lausannevirus and E. lausannensis, respectively. Interestingly, different mutations in the endonuclease encoding genes of Lausannevirus were observed in different subcultures, highlighting the importance of this gene product in the replication of Lausannevirus. Conversely, mutations in E. lausannensis were mainly located in a gene encoding for a phosphoenolpyruvate-protein phosphotransferase (PtsI), implicated in sugar metabolism. Moreover, in our conditions and with our analyses we detected no horizontal gene transfer during one year of co-culture. © The Author(s) 2017.

    Delirium is common in older hip fracture patients, yet its association with mortality after hip fracture remains uncertain. This study aimed to determine whether delirium was associated with all-cause one-year mortality after hip fracture in older patients and whether the effect of delirium was independent of dementia status. A retrospective analysis of linked hospitalisation and mortality data for patients aged ≥65 years with a hip fracture during 1 January 2010 to 30 June 2014 in New South Wales, Australia. The association between delirium and mortality after a hip fracture was assessed using Cox proportional hazard regression. There were 4,065 (14.6%) of 27,888 hip fracture hospitalisations identified with delirium during hospitalisation. Individuals with delirium had a higher age-adjusted rate of all-cause one-year mortality after hip fracture compared to individuals without delirium (35.3% versus 23.9%). After adjusting for covariates, the risk of all-cause mortality was increased at one-year post-admission for older individuals compared to those aged 65-69 years, for individuals with multiple comorbidities, dementia (Hazard Ratio (HR): 1.14; 95%CI:1.08-1.20), delirium (HR: 1.19; 95%CI:1.12-1.26), and who had an Intensive Care Unit admission (HR: 1.44; 95%CI:1.31-1.59). Comorbid delirium did not add additional mortality risk for individuals with a hip fracture who have dementia. Delirium identified in hospital was associated with all-cause one-year mortality after hip fracture in older Australians without dementia. As delirium is potentially preventable, better systematic assessment and documentation of a hip fracture patient's cognitive state is warranted to select the most effective strategies to prevent and manage delirium.

    Full Text Available BACKGROUND: Anxiety is a serious personal health condition and represents a substantial burden to overall quality of life. Additionally anxiety disorders represent a significant cost to the health care system as well as employers through benefits coverage and days missed due to incapacity. This study sought to explore the effectiveness of naturopathic care on anxiety symptoms using a randomized trial. METHODS: Employees with moderate to severe anxiety of longer than 6 weeks duration were randomized based on age and gender to receive naturopathic care (NC (n = 41 or standardized psychotherapy intervention (PT (n = 40 over a period of 12 weeks. Blinding of investigators and participants during randomization and allocation was maintained. Participants in the NC group received dietary counseling, deep breathing relaxation techniques, a standard multi-vitamin, and the herbal medicine, ashwagandha (Withania somnifera (300 mg b.i.d. standardized to 1.5% with anolides, prepared from root. The PT intervention received psychotherapy, and matched deep breathing relaxation techniques, and placebo. The primary outcome measure was the Beck Anxiety Inventory (BAI and secondary outcome measures included the Short Form 36 (SF-36, Fatigue Symptom Inventory (FSI, and Measure Yourself Medical Outcomes Profile (MY-MOP to measure anxiety, mental health, and quality of life respectively. Participants were blinded to the placebo-controlled intervention. RESULTS: Seventy-five participants (93% were followed for 8 or more weeks on the trial. Final BAI scores decreased by 56.5% (p<0.0001 in the NC group and 30.5% (p<0.0001 in the PT group. BAI group scores were significantly decreased in the NC group compared to PT group (p = 0.003. Significant differences between groups were also observed in mental health, concentration, fatigue, social functioning, vitality, and overall quality of life with the NC group exhibiting greater clinical benefit.

    Background To study the prevalence of eighteen geriatric conditions in older patients at admission, their reporting rate in discharge summaries and the impact of these conditions on mortality and functional decline one year after admission. Method A prospective multicenter cohort study conducted between 2006 and 2008 in two tertiary university teaching hospitals and one regional teaching hospital in the Netherlands. Patients of 65 years and older, acutely admitted and hospitalized for at least 48 hours, were invited to participate. Eighteen geriatric conditions were assessed at hospital admission, and outcomes (mortality, functional decline) were assessed one year after admission. Results 639 patients were included, with a mean age of 78 years. IADL impairment (83%), polypharmacy (61%), mobility difficulty (59%), high levels of primary caregiver burden (53%), and malnutrition (52%) were most prevalent. Except for polypharmacy and cognitive impairment, the reporting rate of the geriatric conditions in discharge summaries was less than 50%. One year after admission, 35% had died and 33% suffered from functional decline. A high Charlson comorbidity index score, presence of malnutrition, high fall risk, presence of delirium and premorbid IADL impairment were associated with mortality and overall poor outcome (mortality or functional decline). Obesity lowered the risk for mortality. Conclusion Geriatric conditions were highly prevalent and associated with poor health outcomes after admission. Early recognition of these conditions in acutely hospitalized older patients and improving the handover to the general practitioner could lead to better health outcomes and reduce the burden of hospital admission for older patients.

    Implantable Cardioverter Defibrillators (ICDs), have previously been associated with the onset of depression and anxiety. The aim of this one-year prospective study was to evaluate the rate of new onset psychopathological symptoms after elective ICD implantation. A total of 158 consecutive outpatients who were scheduled for an elective ICD implantation were diagnosed and screened based on the Mini International Neuropsychiatric Interview (MINI). Depression and anxiety were evaluated using the Hamilton Rating Scales for Depression (HAM-D) and Anxiety (HAM-A). Patient's attitude toward the ICD device was evaluated using a Visual Analog Scale (VAS). Patients' mean age was 64±12.4years; 134 (85%) were men, with the majority of patients performing the procedure for reasons of 'primary prevention'. According to the MINI diagnosis at baseline, three (2%) patients suffered from major depressive disorder and ten (6%) from dysthymia. Significant improvement in HAM-D mean scores was found between baseline, three months and one year after implantation (6.50±6.4; 4.10±5.3 and 2.7±4.6, respectively F(2100)=16.42; pdepressive symptoms, while the overall mindset toward the ICD device was positive and improved during the one-year follow-up.

    Objective: To compare the efficacy of multiple doses of vaginal clindamycin with a single oral dose of secnidazole for the treatment of bacterial vaginosis. Study Design: Double-blinded randomized controlled trial. Place and Duration of Study: Shifa Foundation Community Health Center, from March 2012 till February 2015. Methodology: After obtaining written informed consent, a pelvic examination was performed for the confirmation of symptoms of milky white vaginal discharge on speculum examination, positive Amine test and presence of clue cells on microscopy. Pregnant women, known diabetes or any immunocompromised condition, were excluded. Blinding of the patient, doctor, and the pharmacist was done. Study cohort was then divided into two groups, Group A received medicine pack A which contained active clindamycin and placebo oral preparation, whereas group B was given pack B which contained active 2-gm secnidazole with placebo vaginal cream. Primary outcome and therapeutic success were defined by correction of two out of three (normal Nugent score, negative Amine test, and no milky white discharge) on day 15. Results: At 15th day of treatment, 96.6% participants in vaginal clindamycin group (Group A), recovered from the bacterial vaginosis; whereas, (group B) 23% patients were cured in oral secnidazole group. Conclusion: Multiple doses of vaginal clindamycin are superior to single dose of oral secnidazole for the treatment of bacterial vaginosis. (author)

    Long-chain polyunsaturated fatty acids such as docosahexaenoic acid (DHA) influence immune function and inflammation; however, the influence of maternal DHA supplementation on infant morbidity is unknown. We investigated the effects of prenatal DHA supplementation on infant morbidity. In a double-blind randomized controlled trial conducted in Mexico, pregnant women received daily supplementation with 400 mg of DHA or placebo from 18 to 22 weeks' gestation through parturition. In infants aged 1, 3, and 6 months, caregivers reported the occurrence of common illness symptoms in the preceding 15 days. Data were available at 1, 3, and 6 months for 849, 834, and 834 infants, respectively. The occurrence of specific illness symptoms did not differ between groups; however, the occurrence of a combined measure of cold symptoms was lower in the DHA group at 1 month (OR: 0.76; 95% CI: 0.58-1.00). At 1 month, the DHA group experienced 26%, 15%, and 30% shorter duration of cough, phlegm, and wheezing, respectively, but 22% longer duration of rash (all P ≤ .01). At 3 months, infants in the DHA group spent 14% less time ill (P DHA group experienced 20%, 13%, 54%, 23%, and 25% shorter duration of fever, nasal secretion, difficulty breathing, rash, and "other illness," respectively, but 74% longer duration of vomiting (all P DHA supplementation during pregnancy decreased the occurrence of colds in children at 1 month and influenced illness symptom duration at 1, 3, and 6 months.

    In randomized controlled trials (RCTs), outcome variables are often patient-reported outcomes measured with questionnaires. Ideally, all available item information is used for score construction, which requires an item response theory (IRT) measurement model. However, in practice, the classical test theory measurement model (sum scores) is mostly used, and differences between response patterns leading to the same sum score are ignored. The enhanced differentiation between scores with IRT enables more precise estimation of individual trajectories over time and group effects. The objective of this study was to show the advantages of using IRT scores instead of sum scores when analyzing RCTs. Two studies are presented, a real-life RCT, and a simulation study. Both IRT and sum scores are used to measure the construct and are subsequently used as outcomes for effect calculation. The bias in RCT results is conditional on the measurement model that was used to construct the scores. A bias in estimated trend of around one standard deviation was found when sum scores were used, where IRT showed negligible bias. Accurate statistical inferences are made from an RCT study when using IRT to estimate construct measurements. The use of sum scores leads to incorrect RCT results. Copyright © 2016 Elsevier Inc.

    Brief postsurgical electrical stimulation (ES) has been shown to enhance peripheral nerve regeneration in animal models following axotomy and crush injury. However, whether this treatment is beneficial in humans with sensory nerve injury has not been tested. The goal of this study was to test the hypothesis that ES would enhance sensory nerve regeneration following digital nerve transection compared to surgery alone. Patients with complete digital nerve transection underwent epineurial nerve repair. After coaptation of the severed nerve ends, fine wire electrodes were implanted before skin closure. Postoperatively, patients were randomized to receiving either 1 hour of 20Hz continuous ES or sham stimulation in a double-blinded manner. Patients were followed monthly for 6 months by a blinded evaluator to monitor physiological recovery of spatial discrimination, pressure threshold, and quantitative small fiber sensory testing. Functional disability was measured using the Disability of Arm, Shoulder, and Hand questionnaire. A total of 36 patients were recruited, with 18 in each group. Those in the ES group showed consistently greater improvements in all sensory modalities by 5 to 6 months postoperatively compared to the controls. Although there was a trend of greater functional improvements in the ES group, it was not statistically significant (p > 0.01). Postsurgical ES enhanced sensory reinnervation in patients who sustained complete digital nerve transection. The conferred benefits apply to a wide range of sensory functions. © 2015 American Neurological Association.

    Background The World Health Organization's Surgical Safety Checklist has demonstrated significant reduction in surgical morbidity. The American Congress of Obstetricians and Gynecologists District II Safe Motherhood Initiative (SMI) safety bundles include eclampsia and postpartum hemorrhage (PPH) checklists. Objective To determine whether use of the SMI checklists during simulated obstetric emergencies improved completion of critical actions and to elicit feedback to facilitate checklist revision. Study Design During this randomized controlled trial, teams were assigned to use a checklist during one of two emergencies: eclampsia and PPH. Raters scored teams on critical step completion. Feedback was elicited through structured debriefing. Results In total, 30 teams completed 60 scenarios. For eclampsia, trends toward higher completion were noted for blood pressure and airway management. For PPH, trends toward higher completion rates were noted for PPH stage assessment and fundal massage. Feedback resulted in substantial checklist revision. Participants were enthusiastic about using checklists in a clinical emergency. Conclusion Despite trends toward higher rates of completion of critical tasks, teams using checklists did not approach 100% task completion. Teams were interested in the application of checklists and provided feedback necessary to substantially revise the checklists. Intensive implementation planning and training in use of the revised checklists will result in improved patient outcomes. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

METHODS Late-peri and post-menopausal, sedentary women with frequent vasomotor symptoms (VMS) participated in a randomized controlled trial conducted at three sites: 106 to exercise and 142 to usual activity. The exercise intervention consisted of individual, facility-based aerobic exercise training 3 times/week for 12 weeks. VMS frequency and bother were recorded on daily diaries at baseline and weeks 6 and 12. Intent to treat analyses compared between group differences in changes in VMS frequency and bother, sleep symptoms (Insomnia Severity Index, Pittsburgh Sleep Quality Index) and mood (Patient Health Questionnaire-8 and Generalized Anxiety Disorder-7 questionnaire). RESULTS At the end of week 12, changes in VMS frequency in the exercise group (mean change of −2.4/day, 95% CI −3.0, −1.7) and VMS bother (mean change of −0.5 on a 4 point scale, 95% CI −0.6, −0.4) were not significantly different from those in the control group (−2.6 VMS/day, 95% CI −3.2, −2.0, p=0.43; −0.5 points, 95% CI −0.6, −0.4, p=0.75). The exercise group reported greater improvement in insomnia symptoms (p=0.03), subjective sleep quality (p=0.01), and depressive symptoms (p=0.04), but differences were small and not statistically significant when p values were adjusted for multiple comparisons. Results were similar when considering treatment-adherent women only. CONCLUSION These findings provide strong evidence that 12-weeks of moderate-intensity aerobic exercise does not alleviate VMS but may result in small improvements in sleep quality, insomnia and depression in midlife, sedentary women.

    Full Text Available Abstract Background We describe the rationale and protocol for a randomized controlled trial (RCT to assess whether intrauterine contraception placed immediately after a second trimester abortion will result in fewer pregnancies than current recommended practice of intended placement at 4 weeks post-abortion. Decision analysis suggests the novel strategy could substantially reduce subsequent unintended pregnancies and abortions. This paper highlights considerations of design, implementation and evaluation of a trial expected to provide rigorous evidence for appropriate insertion timing and health economics of intrauterine contraception after second trimester abortion. Methods/Design Consenting women choosing to use intrauterine contraception after abortion for a pregnancy of 12 to 24 weeks will be randomized to insertion timing groups either immediately (experimental intervention or four weeks (recommended care post abortion. Primary outcome measure is pregnancy rate at one year. Secondary outcomes include: cumulative pregnancy rates over five year follow-up period, comprehensive health economic analyses comparing immediate and delayed insertion groups, and device retention rates, complication rates (infection, expulsion and, contraceptive method satisfaction. Web-based Contraception Satisfaction Questionnaires, clinical records and British Columbia linked health databases will be used to assess primary and secondary outcomes. Enrolment at all clinics in the province performing second trimester abortions began in May 2010 and is expected to complete in late 2011. Data on one year outcomes will be available for analysis in 2014. Discussion The RCT design combined with access to clinical records at all provincial abortion clinics, and to information in provincial single-payer linked administrative health databases, birth registry and hospital records, offers a unique opportunity to evaluate such an approach by determining pregnancy rate at one

    Full Text Available Abstract Background The registration of clinical trials has been promoted to prevent publication bias and increase research transparency. Despite general agreement about the minimum amount of information needed for trial registration, we lack clear guidance on descriptions of non-pharmacologic interventions in trial registries. We aimed to evaluate the quality of registry descriptions of non-pharmacologic interventions assessed in ongoing randomized controlled trials (RCTs of patient education. Methods On 6 May 2009, we searched for all ongoing RCTs registered in the 10 trial registries accessible through the World Health Organization International Clinical Trials Registry Platform. We included trials evaluating an educational intervention (that is, designed to teach or train patients about their own health and dedicated to participants, their family members or home caregivers. We used a standardized data extraction form to collect data related to the description of the experimental intervention, the centers, and the caregivers. Results We selected 268 of 642 potentially eligible studies and appraised a random sample of 150 records. All selected trials were registered in 4 registers, mainly ClinicalTrials.gov (61%. The median [interquartile range] target sample size was 205 [100 to 400] patients. The comparator was mainly usual care (47% or active treatment (47%. A minority of records (17%, 95% CI 11 to 23% reported an overall adequate description of the intervention (that is, description that reported the content, mode of delivery, number, frequency, duration of sessions and overall duration of the intervention. Further, for most reports (59%, important information about the content of the intervention was missing. The description of the mode of delivery of the intervention was reported for 52% of studies, the number of sessions for 74%, the frequency of sessions for 58%, the duration of each session for 45% and the overall duration for 63

    Full Text Available ABSTRACT The Argentina-Alzheimer's disease neuroimaging initiative (Arg-ADNI study is a longitudinal prospective cohort of 50 participants at a single institution in Buenos Aires, Argentina. Longitudinal assessments on a neuropsychological test battery were performed on 15 controls, 24 mild cognitive impairment (MCI patients and 12 Alzheimer's disease (AD dementia patients. In our study population, there was a high prevalence of positive AD biomarkers in the AD group, 92.3% (12/13; and a low prevalence in the normal controls, 20%; almost half (48% of the patients diagnosed with MCI had positive amyloid detection. After a one year, the significant differences found at baseline on neuropsychological testing were similar at the follow-up assessment even though the AD group had significantly altered its functional performance (FAQ and CDR. The exception was semantic fluency, which showed greater impairment between the AD group and MCI and normal controls respectively. For these tests, the addition of AD biomarkers as a variable did not significantly alter the variations previously found for the established clinical group's model. Finally, the one-year conversion rate to dementia was 20% in the MCI cohort.

    The aim of this study was to investigate the effects of a nine-month supervised resistance training intervention on motivational and volitional characteristics related to exercise, and whether the absolute level and/or intervention-induced change in these characteristics predict self-directed continuation of resistance training one year after the intervention. Community-dwelling older adults aged 65-75, who did not fulfill physical activity recommendations, were randomized into resistance training intervention groups: training once- (n=26), twice- (n=27), three-times-a-week (n=28) or non-training control group (n=25). Training groups participated in supervised resistance training for nine months: during months 1-3 all groups trained twice-a-week and then with allocated frequencies during months 4-9. Exercise-related motivation, self-efficacy and planning were measured with questionnaires at baseline, month-3 and month-9. The continuance of resistance training was determined by interviews six and twelve months after the end of the intervention. The intervention improved action and coping planning as well as intrinsic motivation (group×time p<.05). During one-year follow-up, 54% of participants did not continue self-directed regular resistance training, 22% continued regular resistance training once-a-week and 24% twice-a-week. Increases in exercise self-efficacy and intrinsic motivation related to training during the intervention predicted continuation of resistance training twice-a-week. Resistance training improved exercise-related motivational and volitional characteristics in older adults. These improvements were linked to continuing resistance training one year after the supervised intervention. The role of these characteristics should be taken into account when promoting long-term resistance training participation among older adults. This article is protected by copyright.

    Manual therapy according to the School of Manual Therapy Utrecht (MTU) is a specific type of passive manual joint mobilization. MTU has not yet been systematically compared to other manual therapies and physical therapy. In this study the effectiveness of MTU is compared to physical therapy, particularly active exercise therapy (PT) in patients with non-specific neck pain. Patients neck pain, aged between 18-70 years, were included in a pragmatic randomized controlled trial with a one-year follow-up. Primary outcome measures were global perceived effect and functioning (Neck Disability Index), the secondary outcome was pain intensity (Numeric Rating Scale for Pain). Outcomes were measured at 3, 7, 13, 26 and 52 weeks. Multilevel analyses (intention-to-treat) were the primary analyses for overall between-group differences. Additional to the primary and secondary outcomes the number of treatment sessions of the MTU group and PT group was analyzed. Data were collected from September 2008 to February 2011. A total of 181 patients were included. Multilevel analyses showed no statistically significant overall differences at one year between the MTU and PT groups on any of the primary and secondary outcomes. The MTU group showed significantly lower treatment sessions compared to the PT group (respectively 3.1 vs. 5.9 after 7 weeks; 6.1 vs. 10.0 after 52 weeks). Patients with neck pain improved in both groups without statistical significantly or clinically relevant differences between the MTU and PT groups during one-year follow-up.

    Synchronization under output feedback control with multiple random time delays is studied, using the paradigm in nonlinear physics-Chua's circuit. Compared with other synchronization control methods, output feedback control with multiple random delay is superior for a realistic synchronization application to secure communications. Sufficient condition for global stability of delay-dependent synchronization is established based on the LMI technique. Numerical simulations fully support the analytical approach, in spite of the random delays

    Adequately developed fundamental movement skills, particularly object control dimensions, are considered essential to learn more complex movement patterns and to increase the likelihood to successfully participate in organized and non-organized sports during later years. Thus, the present randomized controlled trial aimed at improving object control dimensions at an early state in a kindergarten setting. Catching, throwing, kicking, rolling and stationary dribbling were assessed via gross motor development 2 (TGMD-2) testing in 41 normally developed preschoolers. On a cluster-randomized basis [strata: age, sex and body mass index (BMI)], three kindergartens were randomly assigned to an intervention group (n = 22, INT, age: 4.6 ± 1.0 years; BMI: 16.2 ± 1.1 kg/m(2) ) and three to a control group (n = 19, CON: age: 4.5 ± 1.2 years; BMI: 16.8 ± 1.2 kg/m(2) ). Twelve structured training sessions were given within 6 weeks (12 sessions). The total training volume was 330 min. Moderate time × group interaction were observed for the total sum score (Δ+22%, P = 0.05) and dribbling (Δ+41%, P = 0.002). Adjusting for baseline differences analyses of covariance did not affect these results. Interestingly, likely to most likely practically worthwhile effects were detected for the total sum score, catching and dribbling. Object control dimensions such as dribbling and catching that apparently rely on rhythmical movement patterns and anticipatory eye-hand coordination seem to benefit from short-term object control training. These skills are considered important for successful team-sport participation and appropriate sportive motor development. © 2015 John Wiley & Sons Ltd.

    Context: Due to the chronic nature of cocaine dependence, long-term maintenance treatments may be required to sustain abstinence. Abstinence reinforcement is among the most effective means of initiating cocaine abstinence. Practical and effective means of maintaining abstinence reinforcement programs over time are needed. Objective: Determine whether employment-based abstinence reinforcement can be an effective long-term maintenance intervention for cocaine dependence. Design: Participants (N=128) were enrolled in a 6-month job skills training and abstinence initiation program. Participants who initiated abstinence, attended regularly, and developed needed job skills during the first six months were hired as operators in a data entry business and randomly assigned to an employment only (Control, n = 24) or abstinence-contingent employment (n = 27) group. Setting: A nonprofit data entry business. Participants: Unemployed welfare recipients who persistently used cocaine while enrolled in methadone treatment in Baltimore. Intervention: Abstinence-contingent employment participants received one year of employment-based contingency management, in which access to employment was contingent on provision drug-free urine samples under routine and then random drug testing. If a participant provided drug-positive urine or failed to provide a mandatory sample, then that participant received a temporary reduction in pay and could not work until urinalysis confirmed recent abstinence. Main Outcome Measure: Cocaine-negative urine samples at monthly assessments across one year of employment. Results: During the one-year of employment, abstinence-contingent employment participants provided significantly more cocaine-negative urine samples than employment only participants (79.3% and 50.7%, respectively; p = 0.004, OR = 3.73, 95% CI = 1.60 – 8.69). Conclusions: Employment-based abstinence reinforcement that includes random drug testing is effective as a long-term maintenance

    Full Text Available The aim of the present study was to determine whether aerobic exercise involving an active video game system improved asthma control, airway inflammation and exercise capacity in children with moderate to severe asthma.A randomized, controlled, single-blinded clinical trial was carried out. Thirty-six children with moderate to severe asthma were randomly allocated to either a video game group (VGG; N = 20 or a treadmill group (TG; n = 16. Both groups completed an eight-week supervised program with two weekly 40-minute sessions. Pre-training and post-training evaluations involved the Asthma Control Questionnaire, exhaled nitric oxide levels (FeNO, maximum exercise testing (Bruce protocol and lung function.No differences between the VGG and TG were found at the baseline. Improvements occurred in both groups with regard to asthma control and exercise capacity. Moreover, a significant reduction in FeNO was found in the VGG (p < 0.05. Although the mean energy expenditure at rest and during exercise training was similar for both groups, the maximum energy expenditure was higher in the VGG.The present findings strongly suggest that aerobic training promoted by an active video game had a positive impact on children with asthma in terms of clinical control, improvement in their exercise capacity and a reduction in pulmonary inflammation.Clinicaltrials.gov NCT01438294.

    Nutritional status has a significant impact on the outcomes in the dialysis population. The aim of this study was to evaluate the association between body composition and a one-year survival of hemodialysis patients. Forty-eight patients with chronic kidney disease stage V treated with hemodialysis for more than three months were included. Body composition was assessed by bioimpedance spectroscopy (Body Composition Monitor, Fresenius Medical Care). Blood samples for serum creatinine, serum albumin, serum prealbumin, high sensitivity C-reactive protein (hsCRP), interleukin 6 (IL-6), insulin-like growth factor 1(IGF-1) concentrations were taken before the midweek dialysis session. Over the course of a one-year observation, seven patients died. We observed a significantly lower lean tissue index (LTI) (p = .013) and higher IL-6 (p = .032) and hsCRP levels (p = .011) among the patients who died. The remaining biochemical markers did not differ between these two groups. Kapplan-Meier analysis revealed a worse survival rate in patients with sarcopenia (lower than the 10th percentile for their age and gender) in comparison with those with normal LTI. However, it was not of statistical significance (p = .055). LTI inversely correlated with age and IL-6 and positively with IGF-1. Sarcopenia defined as decreased LTI, is a relatively common condition among patients undergoing maintenance hemodialysis, it can also be associated with a lower one-year survival rate. Decreased lean tissue mass can be associated with old age, lower IGF-1 levels and higher IL-6 levels. Body composition assessment may provide prognostic data for hemodialysis patients.

    The objective of this study was to investigate change over time in financial abilities in patients with mild Alzheimer disease (AD). The authors conducted a prospective 1-year longitudinal study at a large southern U.S. metropolitan-area medical school university. Participants included healthy older adults (N=63) and patients with mild AD (N=55). The authors conducted a standardized performance measure of financial capacity. Performance was assessed on 18 financial tasks, nine domains of financial activity, and overall financial capacity. Capacity outcomes classifications (capable, marginally capable, or incapable) for domains and overall performance were made using cut scores referenced to comparison group performance. At baseline, patients with mild AD performed significantly below healthy older adults on 16 of 18 tasks, on all nine domains, and on overall financial capacity. At one-year follow up, comparison group performance was stable on all variables. In contrast, patients with mild AD showed substantial declines in overall financial capacity, on eight of nine domains, and on 12 of 18 tasks. Similarly, the proportion of the mild AD group classified as marginally capable and incapable increased substantially over one year for the two overall scores and for five financial domains. Financial capacity is already substantially impaired in patients with mild AD at baseline and undergoes rapid additional decline over one year. Relative to the comparison group, overall financial capacity performance in the AD group declined 10%, from approximately 80% of the comparison group performance at baseline to 70% at follow up. Financial skills showed differential rates of decline on both simple and complex tasks. Of clinical and public policy interest was the declining judgment of patients with mild AD regarding simple fraud schemes. The study supports the importance of prompt financial supervision and planning for patients newly diagnosed with AD.

    Despite the frequency of traumatic injuries due to road accidents and potential importance of identifying children at risk of impaired recovery one year after a road accident, there is a lack of data on long-term recovery of health status, except in children with severe traumatic brain injury. The aim of the present study was to evaluate predictive factors of recovery in children one year after road traffic injuries. The prospective cohort study was composed of children aged road accident. Recovery of health status one year after the accident and information concerning quality of life and the consequences of the accident for the child or family 1 year after the accident were collected by questionnaire, usually completed by the parents. Victims were in majority male (64.6%) and had mild or moderate injuries (81.9% with Maximum Abbreviated Injury Scale (M-AIS) accident, 75.0% of the mild-to-moderate and 34.8% of the severe cases estimated health status as fully recovered. After adjustment, severity score (M-AIS≥3) and lower limb injury (AIS>1) were associated with incomplete recovery of health status: weighted odds ratio (ORw), 4.3 [95% confidence interval (95% CI), 1.3-14.6] and ORw, 6.5 [95% CI, 1.9-21.7], respectively. Recovery status correlated significantly with quality of life physical scores (r=0.46), especially body pain (r=0.48) and role/social-physical (r=0.50) and, to a lesser extent, quality of life psychosocial scores (r=0.21). In a cohort of children injured in a road accident, those with high injury severity score and those with lower limb injuries are less likely to recover full health status by 1 year. Impaired health status was associated with a lower physical quality of life score at 1 year. Copyright © 2014. Published by Elsevier Ltd.

    Reducing the rates of death, trauma and sequelae associated with road accidents is the prime goal of road safety authorities, and success requires having data on victims' outcomes in the long term. The present study examined the outcome of adult road accident victims one year after their accident. A follow-up study. The cohort comprised 886 injured road-accident victims, aged ≥16 years, and living in the Rhône administrative Département, France (taken from the ESPARR Cohort). Data were collected on victim characteristics at the time of crash, and self-reported outcomes one year later. The population of respondents at the one-year questionnaire follow-up was divided into two categories according to injury severity, as mild-to-moderate (M.AISaccident, 45% of the mild-to-moderate injury group versus only 20% of severely injured subjects reported full recovery of health (paccident had had an impact on the everyday life of their family; this was twice as many as in the mild-to-moderate injury group (55% vs. 22%). Most of the severely injured reported impact on leisure, projects and emotional life: 20% reported relational difficulties in the couple, 16% reported impaired sexual life, and the rate of separation was significantly higher than in the mild-to-moderate injury group (5% vs. 1%; proad accident, the consequences for victims remain significant. In terms of physical impact, pain frequently persists, impairing daily life for many.

    Sarcopenic obesity is a risk factor of morbidity and mortality. The aim of this study was to generate a predictive score of sarcopenia occurrence one year after bariatric surgery. We conducted an observational prospective cohort study on a total of 184 severely obese patients admitted to our institution to undergo sleeve gastrectomy. Skeletal muscle cross-sectional area at the third lumbar vertebrae (SMA, cm2) was measured from the routinely performed computed tomography. The skeletal muscle index (SMI) was calculated as follows: SMA/height2 (cm2/m2). Sarcopenia was defined as an SMI predictive sarcopenia occurrence scores were constructed using SMA and gender (SS1 score) or SMI and gender (SS2 score). The area under receiver operating characteristic (AUROC) curve of the SS2 score was significantly greater than that of the SS1 score for the diagnosis of postoperative sarcopenia occurrence (0.95±0.02 versus 0.90±0.02; ppredictive value of 83%, and a negative predictive value of 95%. In the group of patients without baseline sarcopenia, the SS2 score had still an excellent AUROC of 0.92±0.02. A cut-off of 0.55 predicted development of sarcopenia one year after sleeve gastrectomy in these patients with a sensitivity of 87%, a specificity of 88%, and negative predictive value of 95%. The SS2 score has excellent predictive value for the occurrence of sarcopenia one year after sleeve gastrectomy. This score can be used to target early intensification of nutritional and dietetic follow-up to the predicted high-risk population.

    Selective mutism (SM) is a rare disease in children coded by DSM-5 as an anxiety disorder. Despite the disabling nature of the disease, there is still no specific treatment. The aims of this study were to verify the efficacy of six-month standard psychomotor treatment and the positive changes in lifestyle, in a population of children affected by SM. Randomized controlled trial registered in the European Clinical Trials Registry (EuDract 2015-001161-36). University third level Centre (Child and Adolescent Neuropsychiatry Clinic). Study population was composed by 67 children in group A (psychomotricity treatment) (35 M, mean age 7.84±1.15) and 71 children in group B (behavioral and educational counseling) (37 M, mean age 7.75±1.36). Psychomotor treatment was administered by trained child therapists in residential settings three times per week. Each child was treated for the whole period by the same therapist and all the therapists shared the same protocol. The standard psychomotor session length is of 45 minutes. At T0 and after 6 months (T1) of treatments, patients underwent a behavioral and SM severity assessment. To verify the effects of the psychomotor management, the Child Behavior Checklist questionnaire (CBCL) and Selective Mutism Questionnaire (SMQ) were administered to the parents. After 6 months of psychomotor treatment SM children showed a significant reduction among CBCL scores such as in social relations, anxious/depressed, social problems and total problems (Pselective mutism, even if further studies are needed. The present study identifies in psychomotricity a safe and efficacy therapy for pediatric selective mutism.

    Full Text Available Abstract Background The usefulness of hysterosalpingography (HSG as routine investigation in the fertility work-up prior to laparoscopy and dye had been assessed in a randomized controlled trial. Recruiting subjects to the study was more difficult than anticipated. The objective of this study was to explore possible reasons for non-participation in the trial. Methods All newly referred subfertile women admitted to the Reproductive Medicine Clinic of Leiden University Medical Centre between 1 April 1997 and 31 December 1999, were eligible for the study. The reasons for non-participation were evaluated by scrutinizing the medical records. Results Out of 759 women, a total of 127 (17% agreed to participate in the trial. The most important reason for non-participation was because of exclusion criteria (73%. Other reasons were inattentive clinicians (3% and patient-associated reasons (24%. Patient refusal and indecisiveness to enroll in the study were the most common patient-associated reasons. The most frequently stated reason for trial refusal was reluctance to undergo laparoscopy and dye mainly due to issues related to anesthesia and scheduling of procedure. Conclusion Almost three-quarters of recruitment difficulties in this study were due to unavoidable reasons. To overcome the remaining avoidable reasons for non-participation, attention should be paid to appropriate instruction of the study protocol to the participating doctors and to provide adequate information, in layman's terms, to the patients. Reminding patients by notes or telephone calls for attending the clinic are helpful. It may be contingent upon tracing the reasons of clinicians and patients for non-participation to improve enrollment during a trial.

    Full Text Available Abstract Background Evidence-based medicine has been advanced by the use of standards for reporting the design and methodology of randomized controlled trials (RCT. Indeed, without this information it is difficult to assess the quality of evidence from an RCT. Although a variety of statistical methods are available for the analysis of recurrent events, reporting the effect of an intervention on outcomes that recur is an area that remains poorly understood in clinical research. The purpose of this paper is to outline guidelines for reporting results from RCTs where the outcome of interest is a recurrent event. Methods We used a simulation study to relate an event process and results from analyses of the gamma-Poisson, independent-increment, conditional, and marginal Cox models. We reviewed the utility of regression models for the rate of a recurrent event by articulating the associated study questions, preenting the risk sets, and interpreting the regression coefficients. Results Based on a single data set produced by simulation, we reported and contrasted results from statistical methods for evaluating treatment effect from an RCT with a recurrent outcome. We showed that each model has different study questions, assumptions, risk sets, and rate ratio interpretation, and so inferences should consider the appropriateness of the model for the RCT. Conclusion Our guidelines for reporting results from an RCT involving a recurrent event suggest that the study question and the objectives of the trial, such as assessing comparable groups and estimating effect size, should determine the statistical methods. The guidelines should allow clinical researchers to report appropriate measures from an RCT for understanding the effect of intervention on the occurrence of a recurrent event.

    Using the half mouth technique, 33 silver amalgam (Dispersalloy) and 40 glass ionomer (Ketec silver) restorations were placed in the primary molars of children aged five to seven years. After one year, 73 restorations were evaluated. The amalgam restorations rated 90-100 per cent alpha for anatomic form and margins with no recurrent caries or fractures. The glass ionomer restorations rated 35 to 55 per cent alpha for anatomic form and margins with 40 per cent being replaced due to fracture of the material. Within the guidelines of this study, glass ionomer silver cermet was not a suitable material for the restoration of interproximal cavities in primary molars.

    Orthopedic surgeons recognize patient expectations of total knee arthroplasty (TKA) can be managed through education. E-learning is the application of educational technology. The objective of this study was to evaluate whether an e-learning tool could affect whether patients' expectations were met and they were satisfied 1 year following TKA. Patients with osteoarthritis from the London Health Sciences Centre, Canada, were randomly assigned to either a control group (n = 207) receiving standard patient education or an intervention group (n = 209) using the e-learning tool in addition to the standard. We used a web-based system with permuted block sizes, stratified by surgeon and first or second TKA. Preoperative measures were completed following the patients' preadmission clinic visit. Postoperative patient-reported outcome measures were completed at 6 weeks, 3 months, and 1 year after TKA. One year after TKA, risk difference was used to determine between-group differences for patient satisfaction and expectations being met. One year postoperatively, the risk that expectations of patients were not met was 21.8% in the control group and 21.4% in the intervention group for an adjusted risk difference of 1.3% (95% confidence interval, -7.8% to 10.4%, P = .78). The proportion of patients satisfied with their TKA at 1 year postoperative was 78.6% in the intervention and 78.2% in the control groups. There was no between-group difference at 1 year between intervention and control groups for either the risk that expectations of patients were not met or the proportion of patients who were dissatisfied with their TKA.

    Full Text Available INTRODUCTION: Stories may be an effective tool to communicate with patients because of their ability to engage the reader. Our objective was to evaluate the effectiveness of story booklets compared to standard information sheets for parents of children attending the emergency department (ED with a child with croup. METHODS: Parents were randomized to receive story booklets (n=208 or standard information sheets (n=205 during their ED visit. The primary outcome was change in anxiety between triage to ED discharge as measured by the State-Trait Anxiety Inventory. Follow-up telephone interviews were conducted at 1 and 3 days after discharge, then every other day until 9 days (or until resolution of symptoms, and at 1 year. Secondary outcomes included: expected future anxiety, event impact, parental knowledge, satisfaction, decision regret, healthcare utilization, time to symptom resolution. RESULTS: There was no significant difference in the primary outcome of change in parental anxiety between recruitment and ED discharge (change of 5 points for the story group vs. 6 points for the comparison group, p=0.78. The story group showed significantly greater decision regret regarding their decision to go to the ED (p<0.001: 6.7% of the story group vs. 1.5% of the comparison group strongly disagreed with the statement "I would go for the same choice if I had to do it over again". The story group reported shorter time to resolution of symptoms (mean 3.7 days story group vs. 4.0 days comparison group, median 3 days both groups; log rank test, p=0.04. No other outcomes were different between study groups. CONCLUSIONS: Stories about parent experiences managing a child with croup did not reduce parental anxiety. The story group showed significantly greater decision regret and quicker time to resolution of symptoms. Further research is needed to better understand whether stories can be effective in improving patient-important outcomes. TRIAL REGISTRATION

    We present a global EM induction study using L1b Swarm satellite magnetic field measurements data down to a depth of 2000 km. Starting from raw measurements, we first derive a model for the main magnetic field, correct the data for a lithospheric field model, and further select the data to reduce the contributions of the ionospheric field. These computations allowed us to keep a full control on the data processes. We correct residual field from outliers and estimate the spherical harmonic coefficients of the transient field for periods between 2 and 256 days. We used full latitude range and all local times to keep a maximum amount of data. We perform a Bayesian inversion and construct a Markov chain during which model parameters are randomly updated at each iteration. We first consider regular layers of equal thickness and extra layers are added where conductivity contrast between successive layers exceed a threshold value. The mean and maximum likelihood of the electrical conductivity profile is then estimated from the probability density function. The obtained profile particularly shows a conductivity jump in the 600-700 km depth range, consistent with the olivine phase transition at 660 km depth. Our study is the first one to show such a conductivity increase in this depth range without any a priori informations on the internal strucutres. Assuming a pyrolitic mantle composition, this profile is interpreted in terms of temperature variations in the depth range where the probability density function is the narrowest. We finally obtained a temperature gradient in the lower mantle close to adiabatic.

    A year has passed since the nuclear power plant accident in Fukushima on March 11, 2011, and a survey for public perception on radiation by Korean people has been made. The methodological design was based on a quantitative survey and a frequency analysis was done. The analysis objects were survey papers (n=2,754pcs) answered by random ordinary citizens chosen from all over the country. The questionnaires, and study tool, were directly distributed and collected. A total of 40 questionnaires using a coefficient of Cronbach's α per each area was 'self perception of radiation' (0.620), 'radiation risk' (0.830), 'benefit from radiation' (0.781), 'radiation controlled' (0.685), 'informative source of radiation' (0.831), 'influence degree from Fukushima accident' (0.763), showing rather high score from all areas. As the result of the questionnaires, the knowledge of radiation concept was 69.50 out of 100 points, which shows a rather significant difference from the result of 'know well about radiation' (53.7%) and 'just know about radiation' (37.40%). According to the survey, one of the main reasons why radiation seems risky was that once exposed to radiation, it may not have negative impacts presently but, the next generation could see negative impacts (66.1%). About 41% of our respondents showed a negative position against the government's report on radiation while 39.5% of respondents said that we should stop running nuclear power in light of Fukushima nuclear power plant accident. This study was done for the first time by Korean people's public perception on radiation after the Fukushima nuclear power plant accident. We expect this might have significant contributions to the establishment of the government's policy on radiation.

    The maintenance of weight loss may be influenced by the distribution of macronutrients in the diet and insulin sensitivity. The objective of the study was to evaluate the longterm effect of two hypocaloric diets with different protein/carbohydrate ratios in overweight and obese individuals either with insulin resistance (IR) or without insulin resistance (IS). Prospective, randomized, clinical intervention study. Forty patients were classified as IR/IS after a 75 g oral glucose tolerance test and then randomized to a diet with either 40% carbohydrate/30% protein/30% fat (diet A) or 55% carbohydrate/15% protein/30% fat (diet B). After one year of follow-up there was no difference in weight loss between diets A and B in each group, but the IS group maintained weight loss better than the IR group [-5.7 (3.9) vs. -0.6 (4.1); P = 0.04]. No differences were found in either Homeostasis Model Assessment (HOMA) or other metabolic glucose parameters except lower insulin at 120 minutes with diet A [21.40 (8.30) vs. 71.40 (17.11); P = 0.02]. The hypocaloric diets with different protein/carbohydrate ratios produced similar changes in weight. Insulin resistance may play a negative role in maintaining weight loss.

    Medical training is very demanding and associated with a high prevalence of psychological distress. Compared to the general population, medical students are at a greater risk of developing a psychological disorder. Various attempts of stress management training in medical school have achieved positive results on minimizing psychological distress; however, there are often limitations. Therefore, the use of a rigorous scientific method is needed. The present study protocol describes a randomized controlled trial to examine the effectiveness of a specifically developed mindfulness-based stress prevention training for medical students that includes selected elements of cognitive behavioral strategies (MediMind). This study protocol presents a prospective randomized controlled trial, involving four assessment time points: baseline, post-intervention, one-year follow-up and five-year follow-up. The aims include evaluating the effect on stress, coping, psychological morbidity and personality traits with validated measures. Participants are allocated randomly to one of three conditions: MediMind, Autogenic Training or control group. Eligible participants are medical or dental students in the second or eighth semester of a German university. They form a population of approximately 420 students in each academic term. A final total sample size of 126 (at five-year follow-up) is targeted. The trainings (MediMind and Autogenic Training) comprise five weekly sessions lasting 90 minutes each. MediMind will be offered to participants of the control group once the five-year follow-up is completed. The allotment is randomized with a stratified allocation ratio by course of studies, semester, and gender. After descriptive statistics have been evaluated, inferential statistical analysis will be carried out with a repeated measures ANOVA-design with interactions between time and group. Effect sizes will be calculated using partial η-square values. Potential limitations of this study

    Hypoxic hepatitis (HH) is the most frequent cause of acute liver injury in critically ill patients. No clinical data exist about new onset of jaundice in patients with HH. This study aimed to evaluate the incidence and clinical effect of jaundice in critically ill patients with HH. Two hundred and six consecutive patients with HH were screened for the development of jaundice during the course of HH. Individuals with preexisting jaundice or liver cirrhosis at the time of admission (n = 31) were excluded from analysis. Jaundice was diagnosed in patients with plasma total bilirubin levels >3 mg/dL. One-year-survival, infections, and cardiopulmonary, gastrointestinal (GI), renal, and hepatic complications were prospectively documented. New onset of jaundice occurred in 63 of 175 patients with HH (36%). In patients who survived the acute event of HH, median duration of jaundice was 6 days (interquartile range, 3-8). Patients who developed jaundice (group 1) needed vasopressor treatment (P jaundice (group 2). One-year survival rate was significantly lower in group 1, compared to group 2 (8% versus 25%, respectively; P jaundice was associated with an increased frequency of complications during follow-up (54% in group 1 versus 35% in group 2; P Jaundice is a common finding during the course of HH. It leads to an increased rate of complications and worse outcome in patients with HH. Copyright © 2012 American Association for the Study of Liver Diseases.

    We report the synthesis, characterization and use of a robust surface enhanced Raman spectroscopy platform with a stable detection for up to one year of Rhodamine R6G at a concentration of 10{sup −6} M. The detection of aminothiophenol and methyl parathion, as active molecules of commercial insecticides, is further demonstrated at concentrations down to 10{sup −5}–10{sup −6} M. This platform is based on large scale textured few-layer (fl) graphene obtained without any need of graphene transfer. The synthesis route is based on diamond-like carbon films grown by pulsed laser deposition, deposited onto silicon substrates covered by a Ni layer prior to diamond-like carbon deposition. The formation of fl-graphene film, confirmed by Raman spectroscopy and mapping, is obtained by thermal annealing inducing the diffusion of Ni atoms and the concomitant formation of nickel silicide compounds, as identified by Raman and Auger electron spectroscopies. The textured fl-graphene films were decorated with gold nanoparticles to optimize the efficiency of the SERS device to detect organic molecules at low concentrations. - Highlights: • Synthesis of graphene film from amorphous carbon by pulsed laser deposition with nickel catalyst • Large scale textured graphene with nanoscale roughness obtained through nickel silicide formation • Films used for surface enhanced Raman spectroscopy detection of organophosphate compounds • Stability of the SERS platforms over up to one year.

    Full Text Available BACKGROUND Giant cell-rich lesions constitute a group of biologically and morphologically diverse bone and joint tumours. The common feature is presence of numerous multinucleated osteoclast-like giant cells. However, they differ from each other by in terms of clinical and radiographic features and in many cases by their distinct morphological features. METHODS All the bone and joint specimens with giant cell-rich lesions received in the period of one year were studied along with clinical and radiological data available. Gross and microscopic findings were noted. RESULTS In a period of one year, 10 cases of giant cell-rich lesions of bone and joints have been studied, which were and correlated with clinical and radiological findings. Five were lesions from bone and two were from joints, which are chondroblastoma, chondromyxoid fibroma, osteoclastoma, aneurysmal bone cyst, pigmented villonodular synovitis, giant cell lesion of tendon sheath, and tendinous xanthoma. CONCLUSION In the present study, variety of giant cell lesions of bone and joints are studied. Of which, the mean age in young patients being 20 years and in elderly patients being 50 years. The common site being lower end of femur.

    We aimed to assess whether the National Health Service (NHS) Health Check, a systematic cardiovascular disease (CVD) risk assessment and management program, was associated with reduction in CVD risk in attendees after one year. We extracted data from patients aged 40-74 years, with high estimated CVD risk, who were registered with general practices in a deprived, culturally diverse setting in England. We included 4748 patients at baseline (July 2008-November 2009), with 3712 at follow-up (December 2009-March 2011). We used a pre-post study design to assess changes in global CVD risk, individual CVD risk factors and statin prescription in patients with a complete and partial Health Check. There were significant reductions in mean CVD risk score (28.2%; 95% confidence interval (CI)=27.3-29.1 to 26.2%; 95% CI, 25.4-27.1), diastolic blood pressure, total cholesterol levels and lipid ratios after one year in patients with a complete Health Check. Statin prescription increased from 14.0% (95% CI=11.9-16.0) to 60.6% (95% CI=57.7-63.5). The introduction of NHS Health Check was associated with significant but modest reductions in CVD risk among screened high-risk individuals. Further cost-effectiveness analysis and work accounting for uptake is required to assess whether the program can make significant changes to population health. Copyright © 2013 Elsevier Inc.

    Hysteroscopic flexible micro-insert (Essure) is an ambulatory improvement of fallopian tube sterilization, which is a deliberated suppression of fertility. The aim of this study was an evaluation of feasibility (learning curve) and the first year outcome of this method. This prospective study, carried out between February 2002 and March 2003, included patients who were matching with manufacturer recommendations. One surgeon only realized all the device placements. Fifty patients were included (one year follow-up). Mean age was 41 (+/-3.3), mean parity was 2.7 (+/-0.8). Mean time needed for device placement was 26 minutes (+/-6.5) and was reduced with increased experience. Six failures of placement (12%) were related, because of submucus leiomyomas, proximal tubal stenotic disease or too retroverted uterus. Only 5 patients (11,4%) described intensive pelvic pain during the placement. The only case of device expulsion benefited from a successful second placement. The one-year follow-up showed no significant difference of body weight increasing, duration or quantity of menstruation, neither significant pelvic pain nor vaginal bleeding. Tolerance was rated at least at "somewhat satisfied". There have been no pregnancies reported in 670 woman-months of effectiveness. Our results agree in any point with those of larger studies. We think that hysteroscopy micro-insert placement is not only reserved to specialized centers but also to any gynecologist who is used to performing hysteroscopy because of its feasibility.

    Full Text Available Background Malnutrition in children under the age of five remains a major health problem, since half of mortality cases in this age group involve malnutrition. The 2006 earthquake caused destruction of physical, biological and socio-economic environments, potentially leading to malnutrition in Yogyakarta children. Objective To identify the prevalence and risk factors of malnutrition in Yogyakarta children under five years of age, one year after the 2006 earthquake. Methods We conducted a cross-sectional study among children aged 0 to 60 months in the Bambanglipuro Subdistrict, Bantul Regency, Yogyakarta from September to October 2007. Nutritional status was determined using weight for height Z-scores, according to the WHO 2006 Child Growth Standards. Results Out of 666 subjects, we found severe malnutrition, undernutrition, normal weight, and overweight status in 1.7%, 4.8%, 88.6% and 4.8%, respectively. By multivariate analysis, risk factors for malnutrition were not having been weighed during the previous three months (OR 0.35; 95% CI 0.1 to 0.8 and having acute respiratory infection in the previous two weeks (OR 1.99; 95% CI 1.1 to 3.8 Conclusion One year following the 2006 earthquake, acute respiratory infection in the previous two weeks and unmonitored growth in the previous three months were risk factors for malnutrition in children under five years.

    OBJECTIVE To estimate the probability of successful sterilization after hysteroscopic or laparoscopic sterilization procedure. METHODS An evidence-based clinical decision analysis using a Markov model was performed to estimate the probability of a successful sterilization procedure using laparoscopic sterilization, hysteroscopic sterilization in the operating room, and hysteroscopic sterilization in the office. Procedure and follow-up testing probabilities for the model were estimated from published sources. RESULTS In the base case analysis, the proportion of women having a successful sterilization procedure on first attempt is 99% for laparoscopic, 88% for hysteroscopic in the operating room and 87% for hysteroscopic in the office. The probability of having a successful sterilization procedure within one year is 99% with laparoscopic, 95% for hysteroscopic in the operating room, and 94% for hysteroscopic in the office. These estimates for hysteroscopic success include approximately 6% of women who attempt hysteroscopically but are ultimately sterilized laparoscopically. Approximately 5% of women who have a failed hysteroscopic attempt decline further sterilization attempts. CONCLUSIONS Women choosing laparoscopic sterilization are more likely than those choosing hysteroscopic sterilization to have a successful sterilization procedure within one year. However, the risk of failed sterilization and subsequent pregnancy must be considered when choosing a method of sterilization. PMID:21775842

    Prehospital code stroke (CS) systems have been proved effective for improving access to specialised medical care in acute stroke cases. They also improve the prognosis of this disease, which is one of the leading causes of death and disability in our setting. The aim of this study is to analyse results one year after implementation of the new code stroke protocol at one hospital in Asturias. We prospectively included patients who were admitted to our tertiary care centre as per the code stroke protocol for the period of one year. We analysed 363 patients. Mean age was 69 years and 54% of the cases were men. During the same period in the previous year, there were 236 non-hospital CS activations. One hundred forty-seven recanalisation treatments were performed (66 fibrinolysis and 81 mechanical thrombectomies or combined treatments), representing a 25% increase with regard to the previous year. Recent advances in the management of acute stroke call for coordinated code stroke protocols that are adapted to the needs of each specific region. This may result in an increased number of patients receiving early care, as well as revascularisation treatments. Copyright © 2016 Sociedad Española de Neurología.

    Polybrominated diphenyl ethers (PBDEs) are flame retardant chemicals used in consumer products. They are common contaminants in human serum and associated with adverse health effects. Our objectives were to characterize PBDE serum concentrations in a New England cohort and assess temporal variability of this exposure biomarker over a one-year period. We collected three repeated measurements at six-month intervals from 52 office workers from the greater Boston (MA, United States) area from 2010 to 2011. The intraclass correlation coefficient for BDEs 28, 47, 99, 100, and 153 ranged from 0.87 to 0.99, indicating that a single serum measurement can reliably estimate exposure over a one-year period. This was true for both lipid adjusted and nonlipid adjusted concentrations. The kappa statistics, quantifying the level of agreement of categorical exposure classification, based on medians, tertiles, or quartiles ranged from 0.67 to 0.90. Some congeners showed nonsignificant increases from sampling round 1 (winter) to round 2 (summer) and significant decreases from round 2 to round 3 (winter). This study highlights the high reliability of a single serum PBDE measurement for use in human epidemiologic studies.

    Osteogenesis imperfecta (OI) is a heritable condition characterized by fragile bones. Our previous studies indicated that serum 25-hydroxyvitamin D (25OHD) concentrations were positively associated with lumbar spine areal bone mineral density (LS-aBMD) in children and adolescents with OI. Here we assessed whether one year of high-dose vitamin D supplementation results in higher LS-aBMD z-scores in youth with OI. A one-year double-blind randomized controlled trial conducted at a pediatric orthopedic hospital in Montreal, Canada. Sixty patients (age: 6.0 to 18.9years; 35 female) were randomized in equal numbers to receive either 400 or 2000international units (IU) of vitamin D, stratified according to baseline bisphosphonate treatment status and pubertal stage. At baseline, the average serum 25OHD concentration was 65.6nmol/L (SD 20.4) with no difference between treatment groups (p=0.77); 21% of patients had results <50nmol/L. Vitamin D supplementation was associated with higher serum 25OHD concentrations in 90% of participants. The increase in mean 25OHD was significantly higher (p=0.02) in the group receiving 2000IU of vitamin D (mean [95% CI]=30.5nmol/L [21.3; 39.6]) than in the group receiving 400IU (15.2nmol/L [6.4; 24.1]). No significant differences in LS-aBMD z-score changes were detected between treatment groups. Thus, supplementation with vitamin D at 2000IU increased serum 25OHD concentrations in children with OI more than supplementation with 400IU. However, in this study where about 80% of participants had baseline serum 25OHD concentrations ≥50nmol/L, this difference had no detectable effect on LS-aBMD z-scores. Copyright © 2016 Elsevier Inc.

    Asymptomatic gastroesophageal reflux (GER) is prevalent in children with asthma. Untreated GER has been postulated to be a cause of inadequate asthma control in children despite inhaled corticosteroid treatment, but it is not known whether treatment with proton pump inhibitors improves asthma control. To determine whether lansoprazole is effective in reducing asthma symptoms in children without overt GER. The Study of Acid Reflux in Children With Asthma, a randomized, masked, placebo-controlled, parallel clinical trial that compared lansoprazole with placebo in children with poor asthma control who were receiving inhaled corticosteroid treatment. Three hundred six participants enrolled from April 2007 to September 2010 at 19 US academic clinical centers were followed up for 24 weeks. A subgroup had an esophageal pH study before randomization. Participating children were randomly assigned to receive either lansoprazole, 15 mg/d if weighing less than 30 kg or 30 mg/d if weighing 30 kg or more (n = 149), or placebo (n = 157). The primary outcome measure was change in Asthma Control Questionnaire (ACQ) score (range, 0-6; a 0.5-unit change is considered clinically meaningful). Secondary outcome measures included lung function measures, asthma-related quality of life, and episodes of poor asthma control. The mean age was 11 years (SD, 3 years). The mean difference in change (lansoprazole minus placebo) in the ACQ score was 0.2 units (95% CI, 0.0-0.3 units). There were no statistically significant differences in the mean difference in change for the secondary outcomes of forced expiratory volume in the first second (0.0 L; 95% CI, -0.1 to 0.1 L), asthma-related quality of life (-0.1; 95% CI, -0.3 to 0.1), or rate of episodes of poor asthma control (relative risk, 1.2; 95% CI, 0.9-1.5). Among the 115 children with esophageal pH studies, the prevalence of GER was 43%. In the subgroup with a positive pH study, no treatment effect for lansoprazole vs placebo was observed for

    Full Text Available The purpose of this investigation was to determine the effects of a high protein diet over a one-year period. Fourteen healthy resistance-trained men completed the study (mean ± SD; age 26.3±3.9 yr; height 178.5±8.4 cm; and average years of training 8.9±3.4 yr. In a randomized crossover design, subjects consumed their habitual or normal diet for 2 months and 4 months and alternated that with a higher protein diet (>3 g/kg/d for 2 months and 4 months. Thus, on average, each subject was on their normal diet for 6 months and a higher protein diet for 6 months. Body composition was assessed via the Bod Pod®. Each subject provided approximately 100–168 daily dietary self-reports. During the subjects’ normal eating phase, they consumed (mean ± SD 29.94±5.65 kcals/kg/day and 2.51±0.69 g/kg/day of protein. This significantly increased (p<0.05 during the high protein phase to 34.37±5.88 kcals/kg/day and 3.32±0.87 g/kg/day of protein. Our investigation discovered that, in resistance-trained men that consumed a high protein diet (~2.51–3.32 g/kg/d for one year, there were no harmful effects on measures of blood lipids as well as liver and kidney function. In addition, despite the total increase in energy intake during the high protein phase, subjects did not experience an increase in fat mass.

    Ankle sprains are the most common sports and physical activity related injury. There is extensive evidence that there is a twofold increased risk for injury recurrence for at least one year post injury. In up to 50% of all cases recurrences result in disability and lead to chronic pain or instability, requiring prolonged medical care. Therefore ankle sprain recurrence prevention in athletes is essential. This RCT evaluates the effect of the combined use of braces and neuromuscular training (e.g. proprioceptive training/sensorimotor training/balance training) against the individual use of either braces or neuromuscular training alone on ankle sprain recurrences, when applied to individual athletes after usual care. This study was designed as three way randomized controlled trial with one year follow-up. Healthy individuals between 12 and 70 years of age, who were actively participating in sports and who had sustained a lateral ankle sprain in the two months prior to inclusion, were eligible for inclusion. After subjects had finished ankle sprain treatment by means of usual care, they were randomised to any of the three study groups. Subjects in group 1 received an eight week neuromuscular training program, subjects in group 2 received a sports brace to be worn during all sports activities for the duration of one year, and group 3 received a combination of the neuromuscular training program and a sports brace to be worn during all sports activities for the duration of eight weeks. Outcomes were assessed at baseline and every month for 12 months therafter. The primary outcome measure was incidence of ankle sprain recurrences. Secondary outcome measures included the direct and indirect costs of recurrent injury, the severity of recurrent injury, and the residual complaints during and after the intervention. The ABrCt is the first randomized controlled trial to directly compare the secondary preventive effect of the combined use of braces and neuromuscular training

    Research and PhDs are relatively rare in family medicine and primary care. To promote research, regular one-year research courses for primary care professionals with a focus on clinical epidemiology were started. This study explores the academic outcomes of the first four cohorts of research courses and surveys the participants' perspectives on the research course. An electronic survey was sent to the research course participants. All peer-reviewed scientific papers published by these students were retrieved by literature searches in PubMed. Primary care in Finland. A total of 46 research course participants who had finished the research courses between 2007 and 2012. Of the 46 participants 29 were physicians, eight nurses, three dentists, four physiotherapists, and two nutritionists. By the end of 2014, 28 of the 46 participants (61%) had published 79 papers indexed in PubMed and seven students (15%) had completed a PhD. The participants stated that the course taught them critical thinking, and provided basic research knowledge, inspiration, and fruitful networks for research. A one-year, multi-professional, clinical epidemiology based research course appeared to be successful in encouraging primary care research as measured by research publications and networking. Activating teaching methods, encouraging focus on own research planning, and support from peers and tutors helped the participants to embark on research projects that resulted in PhDs for 15% of the participants. Clinical research and PhDs are rare in primary care in Finland, which has consequences for the development of the discipline and for the availability of clinical lecturers at the universities. A clinical epidemiology oriented, one-year research course increased the activity in primary care research. Focus on own research planning and learning the challenges of research with peers appeared to enhance the success of a doctoral research course. A doctoral research course encouraged networking, and

    Full Text Available Abstract Background Efficiency and efficacy of organised mammography screening programs have been proven in large randomised trials. But every local implementation of mammography screening has to check whether the well established quality standards are met. Therefore it was the aim of this study to analyse the most common quality indices after introducing organised mammography screening in Tyrol, Austria, in a smooth transition from the existing system of opportunistic screening. Methods In June 2007, the system of opportunistic mammography screening in Tyrol was changed to an organised system by introducing a personal invitation system, a training program, a quality assurance program and by setting up a screening database. All procedures are noted in a written protocol. Most EU recommendations for organised mammography screening were followed, except double reading. All women living in Tyrol and covered by social insurance are now invited for a mammography, in age group 40-59 annually and in age group 60-69 biannually. Screening mammography is offered mainly by radiologists in private practice. We report on the results of the first year of piloting organised mammography screening in two counties in Tyrol. Results 56,432 women were invited. Estimated participation rate was 34.5% at one year of follow-up (and 55.5% at the second year of follow-up; 3.4% of screened women were recalled for further assessment or intermediate screening within six months. Per 1000 mammograms nine biopsies were performed and four breast cancer cases detected (N = 68. Of invasive breast cancer cases 34.4% were ≤ 10 mm in size and 65.6% were node-negative. In total, six interval cancer cases were detected during one year of follow-up; this is 19% of the background incidence rate. Conclusions In the Tyrolean breast cancer screening program, a smooth transition from a spontaneous to an organised mammography screening system was achieved in a short time and with minimal

    Accurate trial reporting facilitates evaluation and better use of study results. The objective of this article is to investigate the quality of reporting of randomized controlled trials (RCTs) in leading orthodontic journals, and to explore potential predictors of improved reporting. The 50 most recent issues of 4 leading orthodontic journals until November 2013 were electronically searched. Reporting quality assessment was conducted using the modified CONSORT statement checklist. The relationship between potential predictors and the modified CONSORT score was assessed using linear regression modeling. 128 RCTs were identified with a mean modified CONSORT score of 68.97% (SD = 11.09). The Journal of Orthodontics (JO) ranked first in terms of completeness of reporting (modified CONSORT score 76.21%, SD = 10.1), followed by American Journal of Orthodontics and Dentofacial Orthopedics (AJODO) (73.05%, SD = 10.1). Journal of publication (AJODO: β = 10.08, 95% CI: 5.78, 14.38; JO: β = 16.82, 95% CI: 11.70, 21.94; EJO: β = 7.21, 95% CI: 2.69, 11.72 compared to Angle), year of publication (β = 0.98, 95% CI: 0.28, 1.67 for each additional year), region of authorship (Europe: β = 5.19, 95% CI: 1.30, 9.09 compared to Asia/other), statistical significance (significant: β = 3.10, 95% CI: 0.11, 6.10 compared to non-significant) and methodologist involvement (involvement: β = 5.60, 95% CI: 1.66, 9.54 compared to non-involvement) were all significant predictors of improved modified CONSORT scores in the multivariable model. Additionally, median overall Jadad score was 2 (IQR = 2) across journals, with JO (median = 3, IQR = 1) and AJODO (median = 3, IQR = 2) presenting the highest score values. The reporting quality of RCTs published in leading orthodontic journals is considered suboptimal in various CONSORT areas. This may have a bearing in trial result interpretation and use in clinical decision making and evidence- based orthodontic treatment interventions. Copyright

    The current state of evidence suggests that community-based exercise programs are beneficial in improving impairment, function, and health status, and are greatly needed for persons with stroke. However, limitations of these studies include risk of bias, feasibility, and cost issues. This single-blinded, randomized controlled trial (RCT) of 216 participants with stroke will compare the effectiveness of a 12-week YMCA community-based wellness program (FIT for FUNCTION) specifically designed for community-dwelling persons with stroke to persons who receive a standard YMCA membership. The primary outcome will be community reintegration using the Reintegration to Normal Living Index at 12 and 24 weeks. Secondary outcomes include measurement of physical activity level using the Rapid Assessment of Physical Activity and accelerometry; balance using the Berg Balance Scale; lower extremity function using the Short Physical Performance Battery; exercise capacity using the 6-min walk test; grip strength and isometric knee extension strength using hand held dynamometry; and health-related quality of life using the European Quality of Life 5-Dimension Questionnaire. We are also assessing cardiovascular health and lipids; glucose and inflammatory markers will be collected following 12-h fast for total cholesterol, insulin, glucose, and glycated hemoglobin. Self-efficacy for physical activity will be assessed with a single question and self-efficacy for managing chronic disease will be assessed using the Stanford 6-item Scale. The Patient Activation Measure will be used to assess the patient's level of knowledge, skill, and confidence for self-management. Healthcare utilization and costs will be evaluated. Group, time, and group × time interaction effects will be estimated using generalized linear models for continuous variables, including relevant baseline variables as covariates in the analysis that differ appreciably between groups at baseline. Cost data will be treated

    Postoperative analgesic interventions are often tested adjunct to basic non-opioid analgesics in randomized controlled trials (RCTs). Consequently, treatment in control groups, and possible assay sensitivity, differs between trials. We hypothesized that postoperative opioid requirements and pain intensities vary between different control groups in analgesic trials. Control groups from RCTs investigating analgesic interventions after total hip and knee arthroplasty were categorized based on standardized basic analgesic treatment. Morphine consumption 0 to 24 hours postoperatively, and resting pain scores at 6 and 24 hours for subgroups of basic treatments, were compared with ANOVA. In an additional analysis, we compared pain and opioid requirements in trials where a non-steroidal anti-inflammatory drug (NSAID) was administered as an intervention with trial where NSAID was administered in a control group. We included 171 RCTs employing 28 different control groups with large variability in pain scores and opioid requirements. Four types of control groups (comprising 78 trials) were eligible for subgroup comparisons. These subgroups received "opioid" alone, "NSAID + opioid", "acetaminophen + opioid", or "NSAID + acetaminophen + opioid", respectively. Morphine consumption and pain scores varied substantially between these groups, with no consistent superior efficacy in any subgroup. Additionally, trials administering NSAID as an intervention demonstrated lower pain scores and opioid requirements than trials where NSAID was administered in a control group. Analgesic treatment in RCT control groups varies considerably. Control groups receiving various combinations of opioid, NSAID and acetaminophen did not differ consistently in pain and opioid requirements. Pain and opioid requirements were lower in trials administering NSAID as an intervention compared with trials administering NSAID in a control group.

    Polysubstance use disorder is prevalent in treatment-seeking patients with substance use disorder (SUD), with a higher risk of developing comorbid psychiatric symptoms, more pervasive deficits in cognitive functions, and inferior treatment results. The present study investigates if individuals with polysubstance use disorder who achieve at least one year of abstinence show greater improvements in satisfaction with life, executive functions, and psychological distress, compared to relapsers and controls. The prospective recovery from polysubstance use disorder assessed with broad output indicators remains understudied. A better understanding of the pattern of recovery of the chosen output indicators could shed light on the recovery process for this group of patients. We investigated changes in satisfaction with life, executive functions and psychological distress over a period of 12months in patients who remained abstinent and in those who relapsed. Subjects with polysubstance use disorder (N=115) were recruited from outpatient and residential treatment facilities; healthy controls (N=34) were recruited by posters exhibited at social welfare and GP offices. Executive functions were assessed by the Behaviour Rating Inventory of Executive Function-Adult self-report version (BRIEF-A), psychological distress by the Symptom Checklist-90-R (SCL-90-R), and satisfaction with life by the Satisfaction With Life Scale (SWLS). Substance use was assessed by self-reports on the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT). Participants were categorized as "relapsers" if they had AUDIT score ≥8, or DUDIT score ≥2 for women and ≥6 for men. Results indicated that the abstinent group had the greatest improvement on all the indicators compared with relapsers and controls. Participants who successfully quit substance use for one year showed improved satisfaction with life, executive functions, and psychological distress

    1980-07-01

    Although there is a continuing clinical interest in the radiological determination of skeletal development in children below one year of age, none of the existing methods is particularly appropriate. We have therefore developed a new and simple method of assessment. This takes into account the dose of radiation and the two aspects of size and maturity of the skeleton; and so we choose to study the lateral view of the tarsus. The calcaneous and talus are ossification centers appearing before birth. The sum of length and height of these centers constitutes the first part of the assessment. The second part of our evaluation includes an appraisal of the cuboid, the third cuneiform and the distal epiphyses of tibia and fibula. For practical purposes we have chosen to relate the two different aspects of skeletal maturity which we have assessed to the weight of the baby.

    Full Text Available Abstract Background Recurrent otitis media is a common problem in young children. Echinacea and osteopathic manipulative treatment have been proposed as preventive measures, but have been inadequately studied. This study was designed to assess the efficacy of Echinacea purpurea and/or osteopathic manipulative treatment (OMT for prevention of acute otitis media in otitis-prone children. Methods A randomized, placebo-controlled, two-by-two factorial trial with 6-month follow-up, conducted 1999 – 2002 in Tucson, Arizona. Patients were aged 12–60 months with recurrent otitis media, defined as three or more separate episodes of acute otitis media within six months, or at least four episodes in one year. Ninety children (44% white non-Hispanic, 39% Hispanic, 57% male were enrolled, of which 84 had follow-up for at least 3 months. Children were randomly assigned to one of four protocol groups: double placebo, echinacea plus sham OMT, true OMT (including cranial manipulation plus placebo echinacea, or true echinacea plus OMT. An alcohol extract of Echinacea purpurea roots and seeds (or placebo was administered for 10 days at the first sign of each common cold. Five OMT visits (or sham treatments were offered over 3 months. Results No interaction was found between echinacea and OMT. Echinacea was associated with a borderline increased risk of having at least one episode of acute otitis media during 6-month follow-up compared to placebo (65% versus 41%; relative risk, 1.59, 95% CI 1.04, 2.42. OMT did not significantly affect risk compared to sham (44% versus 61%; relative risk, 0.72, 95% CI 0.48, 1.10. Conclusion In otitis-prone young children, treating colds with this form of echinacea does not decrease the risk of acute otitis media, and may in fact increase risk. A regimen of up to five osteopathic manipulative treatments does not significantly decrease the risk of acute otitis media. Trial registration ClinicalTrials.gov Identifier: NCT00010465

    Chronic whiplash-associated disorder (WAD) represents a major medical and psycho-social problem. The typical symptomatology presented in WAD is to some extent similar to symptoms of post traumatic stress disorder. In this study we examined if the acute stress reaction following a whiplash injury predicted long-term sequelae. Participants with acute whiplash-associated symptoms after a motor vehicle accident were recruited from emergency units and general practitioners. The predictor variable was the sum score of the impact of event scale (IES) completed within 10 days after the accident. The main outcome-measures were neck pain and headache, neck disability, general health, and working ability one year after the accident. A total of 737 participants were included and completed the IES, and 668 (91%) participated in the 1-year follow-up. A baseline IES-score denoting a moderate to severe stress response was obtained by 13% of the participants. This was associated with increased risk of considerable persistent pain (OR=3.3; 1.8-5.9), neck disability (OR=3.2; 1.7-6.0), reduced working ability (OR=2.8; 1.6-4.9), and lowered self-reported general health one year after the accident. These associations were modified by baseline neck pain intensity. It was not possible to distinguish between participants who recovered and those who did not by means of the IES (AUC=0.6). In conclusion, the association between the acute stress reaction and persistent WAD suggests that post traumatic stress reaction may be important to consider in the early management of whiplash injury. However, the emotional response did not predict chronicity in individuals.

    Full Text Available PURPOSE:Pigment epithelial detachment (PED may be seen in all stages of age-related macular degeneration (ARMD and may lead to poor prognosis. In this study, we retrospectively examined the effect of anti-VEGF treatments in ARMD patients with vascularized PED. METHODS:Medical records of 15 patients with PED secondary to ARMD were reviewed retrospectively. The diagnosis of PED was made with fundoscopy, fundus fluorescein angiography and optical coherence tomography. Patients were treated with intravitreal ranibizumab or/and bevacizumab and followed up for a minimum of one year. PED height and best corrected visual acuity (BCVA was obtained before the first intravitreal anti-VEGF injection and again at the 1st, 3rd, 6th and 12th month after the injection. RESULTS: The mean baseline BCVA was 0.71 ± 0.48 logarithm of the minimal angle of resolution (logMAR unit and the mean baseline PED height was 361 ± 153 µ. The mean injection count per eye was 3.9 ± 2.9. There was a significant reduce in mean PED height (247 ± 177 µ also in 2 eyes PED completely resolved at the end of the follow up period. The mean BCVA at 12th month (0,69 ± 0,37 were not different from the baseline record. CONCLUSIONS: This retrospective case series showed that intravitreal anti-VEGF therapy preserved vision and reduced PED height in PED patients in a one-year follow-up period.

    The aim of this study was to facilitate the distinction between the benign "mini-puberty of early infancy" and precocious puberty (PP). We compared 59 patients (21 boys and 38 girls) seen for pubic hair development before one year of age diagnosed as mini-puberty to 13 patients (2 boys) in whom pubertal development before one year revealed a PP. The boys with mini-puberty presented with pubic hair development and prepubertal testicular volume, with low plasma testosterone concentrations. Their gonadotropin responses to gonadotropin releasing hormone (GnRH) test showed predominant luteinising hormone increase in 9/13. The girls presented with pubic hair development that was accompanied by breast development in 47% of cases, with low plasma estradiol concentrations. Their gonadotropin responses showed predominant follicle-stimulating hormone increase in the 17 evaluated. The patients with PP had organic central PP (5 hypothalamic hamartoma) or idiopathic central PP (n=6), or peripheral PP (one ovarian tumor and one congenital adrenal hyperplasia). The diagnosis was challenging only in 3 girls with idiopathic central PP presenting with prepubertal plasma estradiol concentrations and responses to GnRH test. The diagnosis of PP was easily determined based on the clinical presentation and the pubertal concentrations of testosterone in boys or of estradiol in girls, as was the diagnosis of central or peripheral origin of PP based on gonadotropin response to the GnRH test. Once PP is excluded, these patients need careful follow-up and physician consultation is needed if clinical pubertal signs progress.

    The internet is a communication medium and content distributor that provide information in the general sense but it could be of great utility regarding as the search and retrieval of biomedical information. Search engines represent a great deal to rapidly find information on the net. However, we do not know whether general search engines and meta-search ones are reliable in order to find useful and validated biomedical information. The aim of our study was to verify the reproducibility of a search by key-words (pediatric or evidence) using 9 international search engines and 1 meta-search engine at the baseline and after a one year period. We analysed the first 20 citations as output of each searching. We evaluated the formal quality of Web-sites and their domain extensions. Moreover, we compared the output of each search at the start of this study and after a one year period and we considered as a criterion of reliability the number of Web-sites cited again. We found some interesting results that are reported throughout the text. Our findings point out an extreme dynamicity of the information on the Web and, for this reason, we advice a great caution when someone want to use search and meta-search engines as a tool for searching and retrieve reliable biomedical information. On the other hand, some search and meta-search engines could be very useful as a first step searching for defining better a search and, moreover, for finding institutional Web-sites too. This paper allows to know a more conscious approach to the internet biomedical information universe.

    Full Text Available Introduction: The use of observation units (OUs following emergency departments (ED visits as a model of care has increased exponentially in the last decade. About one-third of U.S. hospitals now have OUs within their facilities. While their use is associated with lower costs and comparable level of care compared to inpatient units, there is a wide variation in OUs characteristics and operational procedures. The objective of this research was to explore the variability in the initial costs of care of placing patients with non-specific chest pain in observation units (OUs and the one-year outcomes. Methods: The author retrospectively investigated medical insurance claims of 22,962 privately insured patients (2009-2011 admitted to 41 OUs. Outcomes included the one-year chest pain/cardiovascular related costs and primary and secondary outcomes. Primary outcomes included myocardial infarction, congestive heart failure, stroke or cardiac arrest, while secondary outcomes included revascularization procedures, ED revisits for angina pectoris or chest pain and hospitalization due to cardiovascular diseases. The author aggregated the adjusted costs and prevalence rates of outcomes for patients over OUs, and computed the weighted coefficients of variation (WCV to compare variations across OUs. Results: There was minimal variability in the initial costs of care (WCV=2.2%, while the author noticed greater variability in the outcomes. Greater variability were associated with the adjusted cardiovascular-related costs of medical services (WCV=17.6% followed by the adjusted prevalence odds ratio of patients experiencing primary outcomes (WCV=16.3% and secondary outcomes (WCV=10%. Conclusion: Higher variability in the outcomes suggests the need for more standardization of the observation services for chest pain patients. [West J Emerg Med. 2015;16(3:395–400.

    Full Text Available Total phenol (TPh and flavonoid (TFd contents, antioxidant and sensorial properties of polyfloral (PH, and polyfloral honey after one year of storage (PHs with dried apricots (20, 30, and 40% were evaluated. In comparison to honey, TPh increased 1.86 times for PH40. After storage time, TPh of PH40s increased slightly lower (1.77 times, compared to PHs. TFd slightly increased, approximately 3.23-fold, from PH to PH40, while PHs showed increase of 5.15-fold for PH40s. Antioxidant activity increased with increasing concentration of apricots in honey. EC50OH varied from 3.36 for PH to 2.29 mg/mL for PH40 and from 3.48 for PHs to 2.68 mg/mL for PH40s; EC50DPPH ranged from 30.60 for PH to 14.95 mg/mL for PH40 and from 31.22 for PHs to 17.43 mg/mL for PH40s; RP0.5 ranged from 66.37 for PH to 31.83 mg/mL for PH40 and from 67.99 for PHs to 35.03 mg/mL for PH40s. Statistical analysis suggested that TPh and TFd were associated with antioxidant activity and colour. Sensory parameters, before and after storage, indicated very good sensory qualities. Phenolic composition, antioxidant capacity, and sensory properties were promoted after addition of dried apricots and these parameters stayed improved, since antioxidant compounds present in dried apricots aided in maintenance of honey properties along one year of storage.

    A year has passed since the nuclear power plant accident in Fukushima on March 11, 2011, and a survey for public perception on radiation by Korean people has been made. The methodological design was based on a quantitative survey and a frequency analysis was done. The analysis objects were survey papers (n=2,754pcs) answered by random ordinary citizens chosen from all over the country. The questionnaires, and study tool, were directly distributed and collected. A total of 40 questionnaires using a coefficient of Cronbach's {alpha} per each area was 'self perception of radiation' (0.620), 'radiation risk' (0.830), 'benefit from radiation' (0.781), 'radiation controlled' (0.685), 'informative source of radiation' (0.831), 'influence degree from Fukushima accident' (0.763), showing rather high score from all areas. As the result of the questionnaires, the knowledge of radiation concept was 69.50 out of 100 points, which shows a rather significant difference from the result of 'know well about radiation' (53.7%) and 'just know about radiation' (37.40%). According to the survey, one of the main reasons why radiation seems risky was that once exposed to radiation, it may not have negative impacts presently but, the next generation could see negative impacts (66.1%). About 41% of our respondents showed a negative position against the government's report on radiation while 39.5% of respondents said that we should stop running nuclear power in light of Fukushima nuclear power plant accident. This study was done for the first time by Korean people's public perception on radiation after the Fukushima nuclear power plant accident. We expect this might have significant contributions to the establishment of the government's policy on radiation.

    Full Text Available Previous studies have found higher levels of serum malondialdehyde (MDA in hepatocellular carcinoma (HCC patients compared to healthy controls and higher MDA concentrations in tumoral tissue of HCC patients than in non-tumoral tissue. However, the association between pre-transplant serum levels of MDA and survival in HCC patients after liver transplantation (LT has not been described, and the aim of the present study was to determine whether such an association exists. In this observational study we measured serum MDA levels in 127 patients before LT. We found higher pre-LT serum MDA levels in 15 non-surviving than in 112 surviving patients one year after LT (p = 0.02. Exact binary logistic regression analysis revealed that pre-LT serum levels of MDA over 3.37 nmol/mL were associated with mortality after one year of LT (Odds ratio = 5.38; 95% confidence interval (CI = from 1.580 to infinite; p = 0.007 adjusting for age of the deceased donor.

    2012-07-01

    Full Text Available Abstract Background Pain relief during labour is a topic of major interest in the Netherlands. Epidural analgesia is considered to be the most effective method of pain relief and recommended as first choice. However its uptake by pregnant women is limited compared to other western countries, partly as a result of non-availability due to logistic problems. Remifentanil, a synthetic opioid, is very suitable for patient controlled analgesia. Recent studies show that epidural analgesia is superior to remifentanil patient controlled analgesia in terms of pain intensity score; however there was no difference in satisfaction with pain relief between both treatments. Methods/design The proposed study is a multicentre randomized controlled study that assesses the cost-effectiveness of remifentanil patient controlled analgesia compared to epidural analgesia. We hypothesize that remifentanil patient controlled analgesia is as effective in improving pain appreciation scores as epidural analgesia, with lower costs and easier achievement of 24 hours availability of pain relief for women in labour and efficient pain relief for those with a contraindication for epidural analgesia. Eligible women will be informed about the study and randomized before active labour has started. Women will be randomly allocated to a strategy based on epidural analgesia or on remifentanil patient controlled analgesia when they request pain relief during labour. Primary outcome is the pain appreciation score, i.e. satisfaction with pain relief. Secondary outcome parameters are costs, patient satisfaction, pain scores (pain-intensity, mode of delivery and maternal and neonatal side effects. The economic analysis will be performed from a short-term healthcare perspective. For both strategies the cost of perinatal care for mother and child, starting at the onset of labour and ending ten days after delivery, will be registered and compared. Discussion This study, considering cost

    Full Text Available Abstract Background Genetic testing for risk of weight gain is already available over the internet despite uncertain benefits and concerns about adverse emotional or behavioral effects. Few studies have assessed the effect of adding genetic test feedback to weight control advice, even though one of the proposed applications of genetic testing is to stimulate preventive action. This study will investigate the motivational effect of adding genetic test feedback to simple weight control advice in a situation where weight gain is relatively common. Methods/design First-year university students (n = 800 will be randomized to receive either 1 their personal genetic test result for a gene (FTO related to weight gain susceptibility in addition to a leaflet with simple weight control advice (‘Feedback + Advice’ group, FA, or 2 only the leaflet containing simple weight control advice (‘Advice Only’ group, AO. Motivation to avoid weight gain and active use of weight control strategies will be assessed one month after receipt of the leaflet with or without genetic test feedback. Weight and body fat will be measured at baseline and eight months follow-up. We will also assess short-term psychological reactions to the genetic test result. In addition, we will explore interactions between feedback condition and gene test status. Discussion We hope to provide a first indication of the clinical utility of weight-related genetic test feedback in the prevention context.

This was a prospective, single centre, open-label, randomized, controlled feasibility and safety trial. The primary endpoint of the study was the rate of device related adverse events (AE) and serious AE (SAE) as a result of using AnapnoGuard (AG) 100 during mechanical ventilation. Secondary endpoints were: (1) mechanical complications rate (2) ICU staff satisfaction; (3) VAP occurrence; (4) length of mechanical ventilation; (5) length of Intensive Care Unit stay and mortality; (6) volume of evacuated subglottic secretions. Sixty patients were randomized to be intubated with the AG endotracheal-tube (ETT) and connected to the AG 100 system allowing Pcuff adjustment and SS aspiration; or with an ETT combined with SS drainage and Pcuff controlled manually. No difference in adverse events rate was identified between the groups. The use of AG system was associated with a significantly higher incidence of Pcuff determinations in the safety range (97.3% vs. 71%; paspirated SS secretions: (192.0[64-413] ml vs. 150[50-200], p = 0.19 (total)); (57.8[20-88.7] ml vs. 50[18.7-62] ml, p = 0.11 (daily)).

    Full Text Available Background: Information about post-acute coronary syndrome (ACS survival have been mostly short-term findings or based on specialized, cardiology referral centers. Objectives: To describe one-year case-fatality rates in the Strategy of Registry of Acute Coronary Syndrome (ERICO cohort, and to study baseline characteristics as predictors. Methods: We analyzed data from 964 ERICO participants enrolled from February 2009 to December 2012. We assessed vital status by telephone contact and official death certificate searches. The cause of death was determined according to the official death certificates. We used log-rank tests to compare the probabilities of survival across subgroups. We built crude and adjusted (for age, sex and ACS subtype Cox regression models to study if the ACS subtype or baseline characteristics were independent predictors of all-cause or cardiovascular mortality. Results: We identified 110 deaths in the cohort (case-fatality rate, 12.0%. Age [Hazard ratio (HR = 2.04 per 10 year increase; 95% confidence interval (95%CI = 1.75–2.38], non-ST elevation myocardial infarction (HR = 3.82 ; 95%CI = 2.21–6.60 or ST elevation myocardial infarction (HR = 2.59; 95%CI = 1.38–4.89 diagnoses, and diabetes (HR = 1.78; 95%CI = 1.20‑2.63 were significant risk factors for all-cause mortality in the adjusted models. We found similar results for cardiovascular mortality. A previous coronary artery disease diagnosis was also an independent predictor of all-cause mortality (HR = 1.61; 95%CI = 1.04–2.50, but not for cardiovascular mortality. Conclusion: We found an overall one-year mortality rate of 12.0% in a sample of post-ACS patients in a community, non-specialized hospital in São Paulo, Brazil. Age, ACS subtype, and diabetes were independent predictors of poor one‑year survival for overall and cardiovascular-related causes.

    The study aim was to assess the impact of reducing the right ventricular (RV) cavity in order to optimize the outcome of tricuspid valve (TV) repair in cases of functional tricuspid regurgitation (FTR) with dilated right ventricle. Between May 2007 and February 2010, a total of 17 patients (six males, 11 females; mean age 69.5 +/- 10.1 years; mean logistic EuroSCORE 24 +/- 13%) with severe FTR and severe RV dilation were included. Echocardiography and magnetic resonance imaging (MRI) were performed for geometric assessment of the right ventricle. Intraoperatively, the lateral RV free wall was plicated to reduce the RV cavum to approximate the papillary muscles and decrease tethering of the TV; a conventional ring annuloplasty was then performed. Follow up included echocardiography and MRI at one month and one year postoperatively. The mean operative time was 157 +/- 30 min, and the cross-clamp time 63 13 min. Postoperatively, the mean bleeding volume was 486 +/- 455 ml, the rethoracotomy rate 5.9%, intensive therapy unit (ITU) stay 6.0 +/- 4.4 days, and hospital stay 19.0 +/- 8.8 days. In-hospital mortality was 17.6%. The mean follow up was 14.4 +/- 2.4 months. The one-year follow up revealed a survival of 82.3%, a slight decrease in RV ejection fraction (from 33.5 +/- 4.2% to 31.7 +/- 5.7%; p = 0.13), a significant reduction in the RV end-diastolic volume index (from 160 +/- 15.6 to 128 +/- 10 ml/m2; p = 0.0001), a reduction in TV tenting area (from 3.3 +/- 0.9 to 0.9 +/- 0.3 cm2; p = 0.0001), and a significant reduction in the ratio of TR jet to right atrial surface area (from 54.8 +/- 8.2% to 14.1 +/- 3.5%; p = 0.0001). In cases of FTR, RV dilation may be considered as a correctable factor at subvalvular level to optimize the outcome of TV repair.

    Argininosuccinate lyase deficiency (ASLD) is a urea cycle disorder (UCD) treated with dietary adjustment and nitrogen scavenging agents. "Pheburane(®)" is a new tasteless and odour-free formulation of sodium phenylbutyrate, indicated in the treatment of UCD.A male patient diagnosed with ASLD was put on treatment with the new formulation of sodium phenylbutyrate (granules) for a period of one year, at 500 mg/kg orally in 3 intakes/day. Plasma glutamine, arginine, citrulline, argininosuccinate, serum sodium, potassium, liver function tests and urine orotate all remained unchanged over this period. There was no difference in mean ammonia levels before and after treatment, and no hyperammonemia episode occurred during treatment with Pheburane(®). An improvement in a measurement of quality of life (QOL) was noted after treatment with Pheburane(®). Good metabolic control and improved QOL were achieved throughout the treatment period.

    Direct oral anticoagulants (DAOC) are indicated for the treatment of venous thromboembolism and the prevention of stroke or systemic embolism in patients with non-valvular atrial fibrillation. Given their advantages and friendly use for patient, the prescription of long term DOAC therapy has rapidly increased both as first line treatment while initiating anticoagulation and as a substitute to vitamins K antagonist (VKA) in poorly controlled patients. However, DOAC therapy can also be associated with significant bleeding complications, and in the absence of specific antidote at disposal, treatment of serious hemorrhagic complications under DOAC remains complex. We report and discuss herein five cases of major hemorrhagic complications under DOAC, which were reported to the pharmacological surveillance department over one year at Saint-Louis University Hospital (Paris, France). We further discuss the need for careful assessment of the risk/benefit ratio at time of starting DOAC therapy in daily clinical practice. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Previous trials on acupuncture in alcohol addiction were in outpatients and focused on relapse prevention. Rates of dropout were high and interpretation of results difficult. We compared auricular laser and needle acupuncture with sham laser stimulation in reducing the duration of alcohol withdrawal. Inpatients undergoing alcohol withdrawal were randomly allocated to laser acupuncture (n = 17), needle acupuncture (n = 15) or sham laser stimulation (n = 16). Attempts were made to blind patients, therapists and outcome assessors, but this was not feasible for needle acupuncture. The duration of withdrawal symptoms (as assessed using a nurse-rated scale) was the primary outcome; the duration of sedative prescription was the secondary outcome. Patients randomized to laser and sham laser had identical withdrawal symptom durations (median 4 days). Patients randomized to needle stimulation had a shorter duration of withdrawal symptoms (median 3 days; P = 0.019 versus sham intervention), and tended to have a shorter duration of sedative use, but these differences diminished after adjustment for baseline differences. The data from this pilot trial do not suggest a relevant benefit of auricular laser acupuncture for alcohol withdrawal. A larger trial including adequate sham interventions is needed, however, to reliably determine the effectiveness of any type of auricular acupuncture in this condition.

    1988-04-01

    The Conference reviewed what we have learned after one year from SN 1987a. In particular, new information continues to come in daily on the evolving spectra, including x-rays and γ-rays. We now know the light curve was indeed powered by 56 Co decay. The neutrino data from IMB and Kamioka continues to be analyzed. It is fit very well by a standard collapse to a neutron star although some nagging problems with the angular distribution remain. Constraints on neutrino and other weakly interacting particle properties have been developed that rival or exceed terrestrial laboratory results. The question of the counts detected by the Mt. Blanc neutrino detector had new mysteries added at this meeting as reports of multiple coincidences with gravitational wave detectors at Maryland and Rome were presented. Future supernova rates were also discussed. It was argued that neutrino detection from a future supernova in our Galaxy might be the only way to prove that the ν/sub /tau// was the dominant matter of the Universe

    This study attempted to further understanding of factors affecting the teacher efficacy beliefs of secondary science preservice teachers, and to develop a model relating teacher efficacy to beliefs about teaching and students. A mixed quantitative and qualitative methodology was utilized in order to track participants' beliefs both broadly and in depth throughout a one-year teacher preparation program. Results from this analysis revealed that preservice teachers at the end of the program had significantly higher personal science teaching efficacy beliefs than at the beginning of the program. No significant difference in science teaching outcome expectancy beliefs was found, although individual preservice teachers did develop alternate beliefs. Teacher efficacy beliefs were directly affected by three of Bandura's four sources of self-efficacy beliefs---Mastery experiences, vicarious experiences, and verbal persuasion---with the influence of each source of self-efficacy information appearing to change during the course of the teacher preparation program. No evidence was found that affective states by themselves had resulted in belief changes, although many of the other experiences were more powerful because they were accompanied by an emotional incident. Connections between teacher efficacy beliefs, beliefs about students, and beliefs about teaching were uncovered, as was the importance of content knowledge and pedagogical content knowledge on a teacher's sense of efficacy.

    Concern about exposure to drugs, radiation, or infection during pregnancy occur often because pregnancy is not always planned. A teratology information service offers rapid scientific counseling to all those worried about prenatal exposure. The aim of this study is to present data on the most common pharmaceutical products responsible for teratogenic risk in the one-year experience of a teratology information service in Italy. The survey was conducted among 8664 callers who contacted our Teratology Information Service in Rome between January and December 2006. Data on maternal age, gravidity, parity, maternal health status, and details of exposure (dose and timing) were collected and stored in a specific data base. Scientific counseling on prenatal exposure was given to the caller by a specialized service operator, specifying the type of risk and suggesting appropriate tests for prenatal diagnosis. Most of the people called regarding drug exposure; increased risk was present in only 5% of the pregnant women calling during pregnancy. Selective serotonin reuptake inhibitors (SSRIs) are the first category that are actually considered of increased risk to the fetus. The second category is represented by antiepileptic drugs. This experience confirms previous data that there is a high teratological risk perception among both women and physicians. The drugs estimated to present increased risk are medications used for chronic neurological diseases, mainly mood disorders and epilepsy. Preconceptional counseling for these women could be an effective strategy to prevent such exposure and to improve maternal and fetal outcome.

    The spent nuclear fuel reprocessing process is one of the anthropogenic sources of carbon-14, and since this element is highly mobile in the geosphere, its sequestration is necessary. Several phases and industrial solutions to immobilize this radionuclide have been studied, including the barytocalcite phase BaCa(CO{sub 3}){sub 2} at 8.08 wt.% of C, which has many advantages such as its low specific volume of carbon. Recently, different options to synthesize this phase have been reported. Here we report on the aqueous durability of barytocalcite, studied for one year with pure water at 30 °C, in order to complete the behavior studies. Unexpected leaching behavior was encountered: it had been supposed that barytocalcite would only leach slowly, but after 1 year, it was no longer present. It appears that its simple CaCO{sub 3} and BaCO{sub 3} constituents precipitated, though the overall carbon loss was low during the period studied. This research gives a new insight into the behavior of this phase regarding carbon-14 immobilization.

    Full Text Available The purpose of this study was to record injuries in track & field events that were sustained by students who attended the athletic schools during a one-year period. From September 2009 to May 2010, the researchers observed 2045 students (883 males and 1163 females, who were participating in track and field events at the mentioned schools. During the study period 150 injuries were recorded, which accounted for 13.3% of all injuries sustained by students. Most of the injuries (34% according to the diagnosis were sprains and strains and occurred during the months of February, December and January. A large percentage of the injuries (45.4% were sustained by students who attended the Athletic Schools, which operated in the urban region. Students who attended the second class sustained more injuries than the other classes (first and third. Students who were practising or competing on a tartan playing surface were more likely to sustain an injury. Knee and ankle were the most frequent anatomical sites in which injuries (43.9% occurred. Additionally, 80.0% of injuries occurred in students who were practising or competing in running events. No statistical differences were observed in all above mentioned parameters amongst male and female students. Physical education (P.E. teachers should place more emphasis on prevention measures. These measures should include proper supervision of students during training, warming up and cooling down sessions with stretching techniques. By following these suggestions students will compete in a safe and healthy environment.

    This study aimed at evaluating whether ultrasound monitoring of moderate asymptomatic carotid stenosis may help in identifying subjects at high risk for vascular events. We included 523 subjects with unilateral asymptomatic carotid stenosis of 50% to 69%. Follow-up carotid ultrasound was performed within 12 months from inclusion to detect the frequency and degree of stenosis progression. Subjects were prospectively evaluated for a median period of 42 months (interquartile range, 38-45) after a second ultrasound evaluation. Outcome measures were any stroke and transient ischemic attack, myocardial infarction, and death. Carotid stenosis progression was associated with the occurrence of vascular events (hazard ratio, 21.57; 95% confidence interval, 11.81-39.39; P<0.001). During follow-up, 96.7% of subjects without progressive carotid stenosis remained free from vascular events. Among patients with progressive stenosis, 53.7% experienced a vascular event and 27.1% experienced an ipsilateral stroke. One-year moderate asymptomatic carotid stenosis progression is related to higher risk of vascular events, including ipsilateral stroke.

    The HARPS spectrograph is showing an extreme stability, close to the m s{sup −1} level, over more than 10 years of data. However, the radial velocities of some stars are contaminated by a spurious one-year signal with an amplitude that can be as high as a few m s{sup −1}. This signal is in opposition of phase with the revolution of Earth around the Sun and can be explained by the deformation of spectral lines crossing block stitchings of the CCD when the spectrum of an observed star is alternatively blueshifted and redshifted due to the motion of Earth around the Sun. This annual perturbation can be suppressed by either removing those affected spectral lines from the correlation mask used by the cross-correlation technique to derive precise radial velocities, or by simply fitting a yearly sinusoid to the radial velocity data. This is mandatory if we want to detect long-period low-amplitude signals in the HARPS radial velocities of quiet solar-type stars.

    Our aim is to present the first year of operation of a Clinical Psychology service in a Primary Care setting. A descriptive study was performed by analysing the requests and the care intervention of the Psychology Service, in collaboration with 36 general practitioners (33% of the staff), belonging to 6 health centres. Within the one year period, 171 outpatients from 15 years and older were referred with mild psychological disorders (> 61 in the global assessment functioning scale, APA, 2002). A total of 111 outpatients received psychological care. The main diagnoses were adaptation disorder, affective disorder, and anxiety. More than half (54.82%) of them achieved a full recovery. After a year follow up, a drop of 25.19% was observed in medicines use. The Primary Care Psychology team is a halfway unit between Primary Care practitioners and specialised units in order to deal with mild mental symptomatology which otherwise could be undertreated. It represents an important support for practitioners. Secondly, the early intervention can prevent mental problems becoming chronic, as shown by the drop in medication use. In spite of the not very high agreement between the practitioner's diagnoses and those made by the Psychology unit, it has set up an important means of communication and with direct and immediate interdisciplinary action. This should eventually lead to savings in economic resources and human suffering. Copyright © 2014. Publicado por Elsevier España, S.L.U.

    Establishing a diverse gut microbiota after birth is being increasingly recognised as important for preventing illnesses later in life. It is well established that bacterial diversity rapidly increases post-partum; however, few studies have examined the infant gut virome\\/phageome during this developmental period. We performed a metagenomic analysis of 20 infant faecal viromes at one year of age to determine whether spontaneous vaginal delivery (SVD) or caesarean section (CS) influenced viral composition. We find that birth mode results in distinctly different viral communities, with SVD infants having greater viral and bacteriophage diversity. We demonstrate that CrAssphage is acquired early in life, both in this cohort and two others, although no difference in birth mode is detected. A previous study has shown that bacterial OTU\\'s (operational taxonomic units) identified in the same infants could not discriminate between birth mode at 12 months of age. Therefore, our results indicate that vertical transmission of viral communities from mother to child may play a role in shaping the early life microbiome, and that birth mode should be considered when studying the early life gut virome.

    2018-06-01

    Effective modelling and prediction of smaller time step rainfall is reported to be very difficult owing to its highly erratic nature. Accurate forecast of daily rainfall for longer duration (multi time step) may be exceptionally helpful in the efficient planning and management of water resources systems. Identification of inherent patterns in a rainfall time series is also important for an effective water resources planning and management system. In the present study, Singular Spectrum Analysis (SSA) is utilized to forecast the daily rainfall time series pertaining to Koyna watershed in Maharashtra, India, for 365 days after extracting various components of the rainfall time series such as trend, periodic component, noise and cyclic component. In order to forecast the time series for longer time step (365 days-one window length), the signal and noise components of the time series are forecasted separately and then added together. The results of the study show that the method of SSA could extract the various components of the time series effectively and could also forecast the daily rainfall time series for longer duration such as one year in a single run with reasonable accuracy.

    5-Hydroxymethylfurfural (HMF) content is an indicator of the purity of honey. High concentrations of HMF in honey indicate overheating, poor storage conditions and old honey. This study investigated the HMF content of nine Malaysian honey samples, as well as the correlation of HMF formation with physicochemical properties of honey. Based on the recommendation by the International Honey Commission, three methods for the determination of HMF were used: (1) high performance liquid chromatography (HPLC), (2) White spectrophotometry and (3) Winkler spectrophotometry methods. HPLC and White spectrophotometric results yielded almost similar values, whereas the Winkler method showed higher readings. The physicochemical properties of honey (pH, free acids, lactones and total acids) showed significant correlation with HMF content and may provide parameters that could be used to make quick assessments of honey quality. The HMF content of fresh Malaysian honey samples stored for 3-6 months (at 2.80-24.87 mg/kg) was within the internationally recommended value (80 mg/kg for tropical honeys), while honey samples stored for longer periods (12-24 months) contained much higher HMF concentrations (128.19-1131.76 mg/kg). Therefore, it is recommended that honey should generally be consumed within one year, regardless of the type. Copyright (c) 2010 Elsevier Ltd. All rights reserved.

    Full Text Available OBJECTIVE: To analyze the recovery of visual acuity (VA and graft survival after first episode of endothelial rejection in penetrating keratoplasty (PKP treated with intravenous (IV and topic corticosteroid. METHODS: Interventional, prospective, non-comparative case series study evolving 32 PKP patients in one year follow up, who presented first episode of corneal endothelial rejection. The patients were submitted to 500 mg IV injection of methylprednisolone in association with topical prednisolone. Main outcome measures included VA recovery and corneal edema regression. Second outcome included new rejections and graft failure. Multivariate analysis techniques were used to estimate rates of graft outcome events and the impact of risk factors. RESULTS: A total of 32 eyes from 32 patients (13 male and 19 female were included in the study. The mean VA (in number of letters before rejection was 48 (22 to 88 letters. Patients treated within 7 days or less of initial symptoms had better VA recovery, corneal edema regression and less graft failure (p<0.001. Patients with previous ocular surgery had worse VA recovery and more graft failure (p<0.047. CONCLUSION: The association between the other risk factors and the outcomes did not reach statistical significance in the multivariate model because of the small numbers of patients. Methylprednisolone in association with topical prednisolone is an alternative treatment for graft rejection. Our study showed that patients treated within 7 days of symptoms and no previous anterior segment surgery had better visual outcome and graft survival after treatment.

  3. Leaching of metals from sewage sludge during one year and their relationship to particle size

    Leaching of metals from sewage sludge can lead to their accumulation in topsoil and can also contaminate groundwater. Our objectives were to document the metal leachates and the size distribution of leached particles from sewage sludge and to identify possible correlations with physical factors. Results from monthly lysimeter sampling showed an initial release followed by decline for most metals. Cadmium, Ca, Sr, Li, Mn, Ni and Zn showed a 'cyclic' behaviour. Filtration revealed that this 'cyclicity' had no correlation to the size of released particles, but Al, Cr, Fe, Cu, Ag and Pb were clearly related to release of coarser particles most of the year. Total metal amounts leached during one year, relative to original sludge content, had the order Na > Ca = Mg > Mn > Sr > Zn > K > Li = Ni > Cd > Co > Rb > Ag > Cr > Ba = Cu > Ga > Al = Pb = Fe. There were no simple correlations between monthly measured leachate concentrations and precipitation, temperature or pH of precipitation. Occasional leachate sampling might give misleading values for metals with 'cyclic' behaviour. - Cyclic leaching patterns of metals from sewage sludge deserve attention

    Full Text Available Abstract Background Although Cognitive-Behavioral Therapy (CBT is effective for Unexplained Physical Symptoms (UPS, some therapists in clinical practice seem to believe that CBT outcome will diminish if psychiatric comorbidity is present. The result is that patients with a psychiatric comorbidity are redirected from treatment for UPS into treatment for mental health problems. To explore whether this selection and allocation are appropriate, we explored whether CBT outcomes in UPS could be predicted by variables assessed at baseline and used in routine-practice assessments. Methods Patients (n=162 with UPS classified as undifferentiated somatoform disorder or chronic pain disorder were followed up until one year after they had attended a CBT group training. The time-points of the follow-up were at the end of CBT (immediate outcome, three months after CBT (short-term outcome, and one year after CBT (long-term outcome. CBT outcome was measured using the Physical Component Summary of the SF-36, which was the primary outcome measure in the randomized controlled trial that studied effectiveness of the CBT group training. Predictors were: 1. psychological symptoms (global severity score of SCL-90, 2. personality-disorder characteristics (sum of DSM-IV axis II criteria confirmed, 3. psychiatric history (past presence of DSM-IV axis I disorders, and 4. health-related quality of life in the mental domain (mental component summary of SF-36. The effect of this predictor set was explored using hierarchical multiple regression analyses into which these predictors had been entered simultaneously, after control for: a. pretreatment primary outcome scores, b. age, c. gender, d. marital status, and e. employment. Results The predictor set was significant only for short-term CBT outcome, where it explained 15% of the variance. A better outcome was predicted by more psychological symptoms, fewer personality-disorder characteristics, the presence of a psychiatric

    Mindfulness meditation training has been previously shown to enhance behavioral measures of executive control (e.g., attention, working memory, cognitive control), but the neural mechanisms underlying these improvements are largely unknown. Here, we test whether mindfulness training interventions foster executive control by strengthening functional connections between dorsolateral prefrontal cortex (dlPFC)-a hub of the executive control network-and frontoparietal regions that coordinate executive function. Thirty-five adults with elevated levels of psychological distress participated in a 3-day randomized controlled trial of intensive mindfulness meditation or relaxation training. Participants completed a resting state functional magnetic resonance imaging scan before and after the intervention. We tested whether mindfulness meditation training increased resting state functional connectivity (rsFC) between dlPFC and frontoparietal control network regions. Left dlPFC showed increased connectivity to the right inferior frontal gyrus (T = 3.74), right middle frontal gyrus (MFG) (T = 3.98), right supplementary eye field (T = 4.29), right parietal cortex (T = 4.44), and left middle temporal gyrus (T = 3.97, all p < .05) after mindfulness training relative to the relaxation control. Right dlPFC showed increased connectivity to right MFG (T = 4.97, p < .05). We report that mindfulness training increases rsFC between dlPFC and dorsal network (superior parietal lobule, supplementary eye field, MFG) and ventral network (right IFG, middle temporal/angular gyrus) regions. These findings extend previous work showing increased functional connectivity among brain regions associated with executive function during active meditation by identifying specific neural circuits in which rsFC is enhanced by a mindfulness intervention in individuals with high levels of psychological distress.

    The purpose of this research was to compare individual hemoglobin mass (Hb mass ) changes following a live high-train low (LHTL) altitude training camp under either normobaric hypoxia (NH) or hypobaric hypoxia (HH) conditions in endurance athletes. In a crossover design with a one-year washout, 15 male triathletes randomly performed two 18-day LHTL training camps in either HH or NH. All athletes slept at 2,250 meters and trained at altitudes training camp. Hb mass increased similarly in HH (916-957 g, 4.5 ± 2.2%, P noise): 0.9% in HH and 1.7% in NH. However, a correlation between intraindividual ΔHb mass changes (%) in HH and in NH ( r = 0.52, P = 0.048) was observed. HH and NH evoked similar mean Hb mass increases following LHTL. Among the mean Hb mass changes, there was a notable variation in individual Hb mass response that tended to be reproducible. NEW & NOTEWORTHY This is the first study to compare individual hemoglobin mass (Hb mass ) response to normobaric and hypobaric live high-train low using a same-subject crossover design. The main findings indicate that hypobaric and normobaric hypoxia evoked a similar mean increase in Hb mass following 18 days of live high-train low. Notable variability and reproducibility in individual Hb mass responses between athletes was observed, indicating the importance of evaluating individual Hb mass response to altitude training.

    Full Text Available A quantum random walk optimization model and algorithm in network cluster server traffic control and task scheduling is proposed. In order to solve the problem of server load balancing, we research and discuss the distribution theory of energy field in quantum mechanics and apply it to data clustering. We introduce the method of random walk and illuminate what the quantum random walk is. Here, we mainly research the standard model of one-dimensional quantum random walk. For the data clustering problem of high dimensional space, we can decompose one m-dimensional quantum random walk into m one-dimensional quantum random walk. In the end of the paper, we compare the quantum random walk optimization method with GA (genetic algorithm, ACO (ant colony optimization, and SAA (simulated annealing algorithm. In the same time, we prove its validity and rationality by the experiment of analog and simulation.

    The persistence of mineral metabolism disorders after renal transplant (RT) appears to possess a negative impact over graft and patient's survival. To evaluate the parameters of mineral metabolism and the persistence of hyperparathyroidism (HPT) in transplanted patients for a 12-month period after the procedure. Retrospective analysis of 41 transplants (18 women- 44%, mean age of 39 ± 15 years) performed in a University Hospital, evaluating changes of calcium (Ca), phosphorus (P) and parathyroid hormone (PTH) and the prevalence of persistent HPT. The patients were divided into two groups accordingly to PTH levels prior to Tx: Group 1 with PTH ≤ 300 pg/mL (n = 21) and Group 2 with PTH > 300 pg/mL (n = 20). The persistency of HPT after transplant was defined as PTH ≥ 100 pg/mL. The evolution of biochemical parameters and the persistency of HPT were analyzed in each group after 1 year of transplant. After a one-year of follow up, 5% of the patients presented hypophosphatemia (p 10.2 mg/dL) and 48% persistency of HPT (PTH ≥ 100 pg/mL). There was a positive correlation between the PTH pre and post Tx (r = 0.42/p = 0.006) and a negative correlation between PTH and Ca pre-Tx (r = -0.45/p = 0.002). However, there was no significant difference among groups 1 and 2 regarding PTH levels pre and post Tx. The findings in this article suggest that mineral metabolism alterations and the persistency of HPT may occur after one year of renal Tx, mainly in patients which present high PTH levels prior toTx.

    Full Text Available OBJECTIVE: The purpose of this study was to compare spirometry data between patients who underwent single-lung or double-lung transplantation the first year after transplantation. INTRODUCTION: Lung transplantation, which was initially described as an experimental method in 1963, has become a therapeutic option for patients with advanced pulmonary diseases due to improvements in organ conservation, surgical technique, immunosuppressive therapy and treatment of post-operative infections. METHODS: We retrospectively reviewed the records of the 39 patients who received lung transplantation in our institution between August 2003 and August 2006. Twenty-nine patients survived one year post-transplantation, and all of them were followed. RESULTS: The increase in lung function in the double-lung transplant group was more substantial than that of the single-lung transplant group, exhibiting a statistical difference from the 1st month in both the forced expiratory volume in one second (FEV1 and the forced vital capacity (FVC in comparison to the pre-transplant values (p <0.05. Comparison between double-lung transplant and single lung-transplant groups of emphysema patients demonstrated a significant difference in lung function beginning in the 3rd month after transplantation. DISCUSSION: The analyses of the whole group of transplant recipients and the sub-group of emphysema patients suggest the superiority of bilateral transplant over the unilateral alternative. Although the pre-transplant values of lung function were worse in the double-lung group, this difference was no longer significant in the subsequent months after surgery. CONCLUSION: Although both groups demonstrated functional improvement after transplantation, there was a clear tendency to greater improvement in FVC and FEV1 in the bilateral transplant group. Among our subjects, double-lung transplantation improved lung function.

    Recalcitrant sacroiliac joint pain responds well to minimally-invasive surgical (MIS) techniques, although long-term radiographic and fusion data are limited. To evaluate the one-year clinical results from a cohort of patients with chronic sacroiliac (SI) joint pain unresponsive to conservative therapies who have undergone minimally invasive SI joint fusion. SI joint fusion was performed between May 2011 and January 2014. Outcomes included radiographic assessment of fusion status, leg and back pain severity via visual analog scale (VAS), disability via Oswestry Disability Index (ODI) and complication rate. Outcomes were measured at baseline and at follow-up appointments 6 months and 12 months post-procedure. Twenty minimally invasive SI joint fusion procedures were performed on 18 patients (mean age: 47.2 (14.2), mean BMI: 29.4 (5.3), 56% female). At 12 months, the overall fusion rate was 88%. Back and leg pain improved from 81.7 to 44.1 points (p<0.001) and from 63.6 to 27.7 points (p=0.001), respectively. Disability scores improved from 61.0 to 40.5 (p=0.009). Despite a cohort containing patients with multiple comorbidities and work-related injuries, eight patients (50%) achieved the minimal clinically important difference (MCID) in back pain at 12 months, with 9 (69%) patients realizing this improvement in leg pain and 8 (57%) realizing the MCID in ODI scores at 12 months. No major complications were reported. Minimally invasive SI joint surgery is a safe and effective procedure, with a high fusion rate, a satisfactory safety profile and significant improvements in pain severity and disability reported through 12 months post-procedure.

    Purpose: to evaluate the value of MDCT in the monitoring of vertebral body architecture after balloon kyphoplasty and observe morphological changes of the vertebral body. Material and methods: during a period of 26 months, 66 osteoporotic fractures of the vertebral bodies were treated with percutanous balloon kyphoplasty. The height of the vertebral body, width of spinal space, sagittal indices, kyphosis und COBB angle, and cement leakage were evaluated by computed tomography before and after treatment and in a long-term follow up. Statistical analysis was performed by calculating quantitative constant parameters of descriptive key data. In addition, parametric and distribution-free procedures were performed for all questions. Results: after kyphoplasty, the treated vertebral bodies showed a significant gain in the height of the leading edge (0.15 cm; p < 0.0001) and in the central part of the vertebral body (0.17 cm; p < 0.0001). The height of the trailing edge did not change significantly. A corresponding gain in the sagittal index was found. The index remained stable during follow-up. Treated vertebral bodies as well as untreated references showed a comparable loss of height over the period of one year. The shape of the vertebral bodies remained stable. In comparison to these findings, treated vertebral bodies showed a reduced loss of height. A significant change in kyphosis und the COBB angle was noted. In total, pallacos leakage was detected in 71% of cases. Conclusion: MDCT is an accurate method for evaluating vertebral body architecture after treatment with balloon kyphoplasty. (orig.)

    To determine the frequency of anaphylaxis in an allergy outpatient department, allowing a better understanding regarding aetiology, clinical manifestations and management, in children and adolescents. From among 3646 patients up to 18 years old observed during one-year period, we included those with history of anaphylaxis reported by allergists. Sixty-four children had history of anaphylaxis (prevalence of 1.8%), with mean age 8.1±5.5 years, 61% being male. Median age of the first anaphylactic episode was 3 years (1 month-17 years). The majority of patients had food-induced anaphylaxis (84%): milk 22, egg 7, peanut 6, tree nuts 6, fresh fruits 6, crustaceans 4, fish 4 and wheat 2. Food-associated exercise-induced anaphylaxis was reported in 2 adolescents. Drug-induced anaphylaxis occurred in 8%: 4 non-steroidal anti-inflammatory drugs and 1 amoxicillin. Three children had cold-induced anaphylaxis, one adolescent had anaphylaxis to latex and one child had anaphylaxis to insect sting. The majority (73%) had no previous diagnosis of the etiologic factor. Symptoms reported were mainly mucocutaneous (94%) and respiratory (84%), followed by gastrointestinal (42%) and cardiovascular (25%). Fifty-one patients were admitted to the emergency department, although only 33% were treated with epinephrine. Recurrence of anaphylaxis occurred in 26 patients (3 or more episodes in 14). In our paediatric population, the main triggering agent of anaphylaxis was IgE-mediated food allergy. Epinephrine is underused, as reported by others. Often, children have several episodes before being assessed by an allergist. We stress the importance of systematic notification and improvement of educational programmes in order to achieve a better preventive and therapeutic management of this life-threatening entity.

    To determine if the migration of potential contaminants from three inactive waste impoundments at Oak Ridge National Laboratory poses a threat to groundwater quality, at least one upgradient groundwater monitoring well and threee downgradient monitoring wells were installed at each impoundment in early 1985. These three unlined impoundments, formerly used to collect and, in some instances, treat wastewater are: the 3513 impoundment; the Old Hydrofracture Facility (OHF) impoundment; and the Homogeneous Reactor Experimnt No. 2 impoundment. Groundwater samples were collected quarterly for one year. Analyses were conducted for the groundwater protection parameters promulgated by the Resource Conservation and Recovery Act. The groundwater samples were also analyzed for polychlorinated biphenyls, copper, nickel, zinc, /sup 90/Sr, /sup 137/Cs, and tritium. The contaminants found most often to affect groundwater quality at all three waste impoundments were radionuclides. For example, mean concentrations of gross beta and gross alpha activity exceeded drinking water limits at all three sites. The gross beta limit was exceeded at the 3513 and OHF impoundments by either /sup 90/Sr or tritium levels. At the 3513 impoundment, there was substantial evidence that the downgradient groundwater has been contaminated by chromium and lead and possibly by halogenated organic compounds. At the OHF impoundment, the mean level of tritium measured in the upgradient well (about 91,000 Bq/L as compared with 80,000 Bq/L in the downgradient wells) indicated that the groundwater quality has been affected by the radioactive wastes buried in the low-level radioactive waste burial ground solid waste storage area-5 upgradient of the impoundment. Testing for groundwater contamination, disclosed statistically significant contamination at all three sites.

    Two simulated nuclear waste glasses were corroded in an in-situ experiment in the Stripa mine up to one year at 90 degree C and ambient temperature. Changes in compositional in-depth profiles were measured using Fourier transform infrared reflection spectroscopy, SIMS and Rutherford back-scattering. For glass/glass interfaces, both glasses showed depletion of Na, Cs and B, but for the more corrosion resistant glass, the lower depletion is ascribed to the formation of a thin (0.2 nm) coherent and dense outer layer enriched in Mg, Ca, Sr, Ba, Zn-Al and Si, which impedes both ion exchange and network attack of the bulk underneath. For the bentonite interfaces, cation exchange of Ca, Mg, Al and Fe from the bentonite for primarily Na and B is found to produce a glass surface that has three silicate-rich layers. The larger concentrations of M/super2+/ and M/super3+/ cation and the high silica content of the reaction layers result in a considerably retarded rate of ion exchange after the formation of these layers during the first three months of burial. The granite interfaces showed the lowest rate of attack. This appears to be due to a large increase of Fe and Al within the glass surfaces exposed to granite. The results obtained using Rutheford back-scattering confirm the results obtained using the other techniques for surface analysis. Analysis of burial samples cast in steel mini-canisters show no significant effects associated with the steel canister-glass interface. (author)

    Refractory status epilepticus (RSE) is a particular critical condition characterized by seizures that continue despite the use of first- and second-line therapies and by high mortality. To date, only one prospective study investigated clinical features and prognostic factors in RSE. In this study, we performed a one-year prospective survey to identify clinical features, outcomes, and variables associated with the development of RSE in the adolescent and adult population of Modena, northern Italy. We observed 83 episodes of SE in 83 patients. In 31% of the cases, third-line therapy (anesthetic drug) was needed. Among this group, 14% resolved and were classified as RSE, while, in 17%, seizures recurred at withdrawal of anesthetics and were classified as super-RSE. The development of RSE/super-RSE was associated with a stuporous/comatose state at presentation and with the absence of a previous history of epilepsy. Refractory status epilepticus/super-refractory status epilepticus showed a worse outcome compared with responsive SE: 54% versus 21% for 30-day mortality; 19% versus 56% for a return to baseline condition. This prospective study confirms stupor/coma at onset as a relevant clinical factor associated with SE refractoriness. We observed a rate of RSE comparable with previous reports, with high mortality and morbidity. Mortality in the observed RSE was higher than in previous studies; this result is probably related to the low rate of a previous epilepsy history in our population that reflects a high incidence of acute symptomatic etiologies, especially the inclusion of patients with postanoxic SE who have a bad prognosis per se.

    2015-10-01

    Obesity is considered the second most common health problem in pet cats in developed countries. Previous studies investigating risk factors for feline obesity have been cross-sectional, where reverse causality cannot be ruled out. This study is the first to use prospective data from a large scale longitudinal study of pet cats ('Bristol Cats') to identify early-life risk factors for feline overweight/obesity at around one year of age. Data analysed were collected via three owner-completed questionnaires (for cats aged 2-4 months, 6.5-7 months and 12.5-13 months) completed between May 2010 and August 2013. Owner-reported body condition scores (BCS) of cats at age 12.5-13 months, using the 5-point system, were categorised into a dichotomous variable: overweight/obese (BCS 4-5) and not overweight (BCS 1-3) and used as the dependent variable. Cat breed, neuter status, outdoor access, type of diet, frequency of wet and dry food fed and frequency of treats fed were analysed as potential risk factors. Of the 966 cats for which data were available, 7.0% were reported by their owners to be overweight/obese at 12.5-13 months of age. Descriptive data on type of diet fed at different cat ages suggest that a dry diet is the most popular choice for UK domestic cats. Significant potential explanatory variables from univariable logistic regression models were included in multivariable logistic regression models built using stepwise forward-selection. To account for potential hierarchical clustering of data due to multi-cat households these were extended to two-level random intercept models. Models were compared using Wald test p- values. Clustering had no impact on the analysis. The final multivariable logistic regression model identified two risk factors that were independently associated with an increased risk of feline obesity developing at 12.5-13 months of age: restricted or no outdoor access and feeding dry food as the only or major (>50%) type of food in the diet at age 12

    Ankle sprains often result in ankle instability, which is most likely caused by damage to passive structures and neuromuscular impairment. Whole body vibration (WBV) is a neuromuscular training method improving those impaired neurologic parameters. The aim of this study is to compare the current gold standard functional treatment to functional treatment plus WBV in patients with acute unilateral unstable inversion ankle sprains. 60 patients, aged 18-40 years, presenting with an isolated, unilateral, acute unstable inversion ankle sprain will be included in this bicentric, biphasic, randomized controlled trial. Samples will be randomized by envelope drawing. All patients will be allowed early mobilization and pain-dependent weight bearing, limited functional immobilization by orthosis, PRICE, NSARDs as well as home and supervised physiotherapy. Supervised physical therapy will take place twice a week, for 30 minutes for a period of 6 weeks, following a standardized intervention protocol. During supervised physical therapy, the intervention group will perform exercises similar to those of the control group, on a side-alternating sinusoidal vibration platform. Two time-dependent primary outcome parameters will be assessed: short-term outcome after six weeks will be postural control quantified by the sway index; mid-term outcome after one year will be assessed by subjective instability, defined by the presence of giving-way attacks. Secondary outcome parameters include: return to pre-injury level of activities, residual pain, recurrence, objective instability, energy/coordination, Foot and Ankle Disability Index and EQ 5D. This is the first trial investigating the effects of WBV in patients with acute soft tissue injury. Inversion ankle sprains often result in ankle instability, which is most likely due to damage of neurological structures. Due to its unique, frequency dependent, influence on various neuromuscular parameters, WBV is a promising treatment method for

    Full Text Available Introduction: Vitamin D has many immunomodulatory, anti-inflammatory, and neuroprotective functions, and previous studies have demonstrated an association between vitamin D deficiency and neuropsychiatric disease. The aim of our study was to analyze the prevalence of vitamin D deficiency in a one-year cohort of adult inpatients with schizophreniform and autism-spectrum syndromes in a naturalistic in-patient setting in Germany. Participants and methods: Our study was comprised of 60 adult schizophreniform and 23 adult high-functioning autism spectrum patients who were hospitalized Page: 2between January and December of 2015. We compared our findings with a historical German reference cohort of 3,917 adults using Pearson’s two-sided chi-squared test. The laboratory measurements of 25-hydroxyvitamin D2/3 (25(OHvitamin D were obtained using a chemiluminescence immunoassay. Results: In the schizophreniform group, we found decreased ( 30 ng/ml were observed in only 5% of the schizophreniform patients, 8.7% of the autism spectrum patients, and 21.9% of the healthy controls. Discussion: We found very high rates of 25(OHvitamin D deficiency in both patient groups, and have discussed whether our findings might be related to alterations in the immunological mechanisms. Irrespective of the possible pathophysiological links between vitamin D deficiency and schizophrenia or autism spectrum disorders, a more frequent measurement of vitamin D levels seems to be justified in these patient groups. Further prospective, controlled, blinded, and randomized research should be conducted to analyze the effectiveness of vitamin D supplementation on the improvement of psychiatric symptoms.

    Objective To evaluate the characteristics of strabismus in infants who underwent cataract surgery with and without intraocular lens (IOL) implantation. Design Secondary outcome analysis in a prospective, randomized clinical trial Participants The Infant Aphakia Treatment Study (IATS) is a randomized, multicenter (n = 12) clinical trial comparing treatment of aphakia with a primary IOL or contact lens in 114 infants with a unilateral congenital cataract. Intervention Infants underwent cataract surgery with or without placement of an IOL. Main Outcome Measures The proportion of patients who developed strabismus during the first 12 months of follow-up was calculated using the life-table method, and compared across treatment groups and age strata using a log-rank test. Results Strabismus developed within the first 12 months of follow-up in 38 (life table estimate: 66.7%) pseudophakic infants and 42 (life table estimate: 74.5%) infants treated with contact lenses (p=0.59). The younger cohort (strabismus (29 of 50, life table estimate: 58.0%) than the older cohort (≥ 49 days) (51 of 64, life table estimate: 80.0%) (pstrabismus following congenital cataract surgery. However, strabismus was less likely to develop in infants whose cataract was removed at an earlier age. PMID:23419803

    Full Text Available Abstract Background β-thymosins play roles in cytoskeleton rearrangement, angiogenesis, fibrosis and reparative process, thus suggesting a possible involvement in the pathogenesis of systemic sclerosis. The aim of the study was to investigate the presence of thymosins β4, β4 sulfoxide, and β10 in bronchoalveolar lavage fluid of scleroderma patients with interstitial lung disease and the relation of these factors with pulmonary functional and radiological parameters. Methods β-thymosins concentrations were determined by Reverse Phase-High Performance Liquid Chromatography-Electrospray-Mass Spectrometry in the bronchoalveolar lavage fluid of 46 scleroderma patients with lung involvement and of 15 controls. Results Thymosin β4, β4 sulfoxide, and β10 were detectable in bronchoalveolar lavage fluid of patients and controls. Thymosin β4 levels were significantly higher in scleroderma patients than in controls. In addition, analyzing the progression of scleroderma lung disease at one-year follow-up, we have found that higher thymosin β4 levels seem to have a protective role against lung tissue damage. Thymosin β4 sulfoxide levels were higher in the smokers and in the scleroderma patients with alveolitis. Conclusions We describe for the first time β-thymosins in bronchoalveolar lavage fluid and their possible involvement in the pathogenesis of scleroderma lung disease. Thymosin β4 seems to have a protective role against lung tissue damage, while its oxidation product mirrors an alveolar inflammatory status.

    Full Text Available Abstract Background Whether acupuncture is effective for patients with functional constipation is still unclear. Therefore, we report the protocol of a randomized controlled trial of using acupuncture to treat functional constipation. Design A randomized, controlled, four-arm design, large-scale trial is currently undergoing in China. Seven hundred participants are randomly assigned to three acupuncture treatment groups and Mosapride Citrate control group in a 1:1:1:1 ratio. Participants in acupuncture groups receive 16 sessions of acupuncture treatment, and are followed up for a period of 9 weeks after randomization. The acupuncture groups are: (1 Back-Shu and Front-Mu acupoints of Large Intestine meridians (Shu-Mu points group; (2 He-Sea and Lower He-Sea acupoints of Large Intestine meridians (He points group; (3 Combining used Back-Shu, Front-Mu, He-Sea, and Lower He-Sea acupoints of Large Intestine meridians (Shu-Mu-He points group. The control group is Mosapride Citrate group. The primary outcome is frequency of defecation per week at the fourth week after randomization. The secondary outcomes include Bristol stool scale, the extent of difficulty during defecating, MOS 36-item Short Form health survey (SF-36, Self-Rating Anxiety Scale (SAS, and Self-rating Depression Scale (SDS. The first two of second outcomes are measured 1 week before randomization and 2, 4, and 8 weeks after randomization. Other second outcomes are measured 1 week before randomization and 2 and 4 weeks after randomization, but SF-36 is measured at randomization and 4 weeks after randomization. Discussion The result of this trial (which will be available in 2012 will confirm whether acupuncture is effective to treat functional constipation and whether traditional acupuncture theories play an important role in it.

    With a randomized field experiment of 433 preschoolers, we tested a tablet mathematics program designed to increase young children's mathematics learning. Intervention students played Math Shelf, a comprehensive iPad preschool and year 1 mathematics app, while comparison children received research-based hands-on mathematics instruction delivered by their classroom teachers. After 22 weeks, there was a large and statistically significant effect on mathematics achievement for Math Shelf students (Cohen's d = .94). Moderator analyses demonstrated an even larger effect for low achieving children (Cohen's d = 1.27). These results suggest that early education teachers can improve their students' mathematics outcomes by integrating experimentally proven tablet software into their daily routines.

    Full Text Available Abstract Background The practice of evidence-based medicine (EBM requires clinicians to integrate their expertise with the latest scientific research. But this is becoming increasingly difficult with the growing numbers of published articles. There is a clear need for better tools to improve clinician's ability to search the primary literature. Randomized clinical trials (RCTs are the most reliable source of evidence documenting the efficacy of treatment options. This paper describes the retrieval of key sentences from abstracts of RCTs as a step towards helping users find relevant facts about the experimental design of clinical studies. Method Using Conditional Random Fields (CRFs, a popular and successful method for natural language processing problems, sentences referring to Intervention, Participants and Outcome Measures are automatically categorized. This is done by extending a previous approach for labeling sentences in an abstract for general categories associated with scientific argumentation or rhetorical roles: Aim, Method, Results and Conclusion. Methods are tested on several corpora of RCT abstracts. First structured abstracts with headings specifically indicating Intervention, Participant and Outcome Measures are used. Also a manually annotated corpus of structured and unstructured abstracts is prepared for testing a classifier that identifies sentences belonging to each category. Results Using CRFs, sentences can be labeled for the four rhetorical roles with F-scores from 0.93–0.98. This outperforms the use of Support Vector Machines. Furthermore, sentences can be automatically labeled for Intervention, Participant and Outcome Measures, in unstructured and structured abstracts where the section headings do not specifically indicate these three topics. F-scores of up to 0.83 and 0.84 are obtained for Intervention and Outcome Measure sentences. Conclusion Results indicate that some of the methodological elements of RCTs are

    To assess the quality of the randomized clinical trial (RCT) reports published in Endodontics between 1997 and 2012. Retrieval of RCTs in Endodontics was based on a search of the Thomson Reuters Web of Science (WoS) database (March 2013). Quality evaluation was performed using a checklist based on the Jadad criteria, CONSORT (Consolidated Standards of Reporting Trials) statement and SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials). Descriptive statistics were used for frequency distribution of data. Student's t-test and Welch test were used to identify the influence of certain trial characteristics upon report quality (α = 0.05). A total of 89 RCTs were evaluated, and several methodological flaws were found: only 45% had random sequence generation at low risk of bias, 75% did not provide information on allocation concealment, and 19% were nonblinded designs. Regarding statistics, only 55% of the RCTs performed adequate sample size estimations, only 16% presented confidence intervals, and 25% did not provide the exact P-value. Also, 2% of the articles used no statistical tests, and in 87% of the RCTs, the information provided was insufficient to determine whether the statistical methodology applied was appropriate or not. Significantly higher scores were observed for multicentre trials (P = 0.023), RCTs signed by more than 5 authors (P = 0.03), articles belonging to journals ranked above the JCR median (P = 0.03), and articles complying with the CONSORT guidelines (P = 0.000). The quality of RCT reports in key areas for internal validity of the study was poor. Several measures, such as compliance with the CONSORT guidelines, are important in order to raise the quality of RCTs in Endodontics. © 2016 International Endodontic Journal.

    Full Text Available Abstract Background Inadequate and inappropriate complementary feeding are major factors contributing to excess morbidity and mortality in young children in low resource settings. Animal source foods in particular are cited as essential to achieve micronutrient requirements. The efficacy of the recommendation for regular meat consumption, however, has not been systematically evaluated. Methods/Design A cluster randomized efficacy trial was designed to test the hypothesis that 12 months of daily intake of beef added as a complementary food would result in greater linear growth velocity than a micronutrient fortified equi-caloric rice-soy cereal supplement. The study is being conducted in 4 sites of the Global Network for Women's and Children's Health Research located in Guatemala, Pakistan, Democratic Republic of the Congo (DRC and Zambia in communities with toddler stunting rates of at least 20%. Five clusters per country were randomized to each of the food arms, with 30 infants in each cluster. The daily meat or cereal supplement was delivered to the home by community coordinators, starting when the infants were 6 months of age and continuing through 18 months. All participating mothers received nutrition education messages to enhance complementary feeding practices delivered by study coordinators and through posters at the local health center. Outcome measures, obtained at 6, 9, 12, and 18 months by a separate assessment team, included anthropometry; dietary variety and diversity scores; biomarkers of iron, zinc and Vitamin B12 status (18 months; neurocognitive development (12 and 18 months; and incidence of infectious morbidity throughout the trial. The trial was supervised by a trial steering committee, and an independent data monitoring committee provided oversight for the safety and conduct of the trial. Discussion Findings from this trial will test the efficacy of daily intake of meat commencing at age 6 months and, if beneficial, will

    The paper provides a review of one year of military Mental Health (MH) hospital admissions. This includes an exploration into demographic trends, differences in clinical opinion and how information gained is used to improve the service and ensure appropriate, cost effective care in the optimum environment. The sample group is entitled military MH hospital admissions from 1 April 2005 to 31 March 2006. Data was collected on questionnaires with SPSS used for the management and analysis of the quantitative data, with the information exposed to descriptive and inferential statistical analysis. There were 344 admissions. The paper contains a detailed review of a number of variables. Depression was the most common diagnosis resulting in 112 (33%) hospital admissions and Post Traumatic Stress Disorder accounted for 23 (7%). There were statistically significant differences that may be attributable to gender with more women admitted with depression and more men with alcohol related disorders. The average length of stay was 21 days, with 48% of patients discharged within 3 weeks. 45% of all returns included significant events reporting that highlighted written evidence of good and poor practice. This study is part of an extensive monitoring programme of military MH hospital admissions. Depression is the most common MH problem leading to hospital admission. The results indicate that Service-personnel have access to a highly responsive service that provides brief assessment and treatment within a safe therapeutic environment. 45% of returns included significant event information that resulted in policy changes, leading to improved patient care and a better interface with the NHS. Bench-marking, both internally between military Departments of Community Mental Health and externally have improved visibility and self awareness leading to better GP induction programmes, PHC educational seminars and the establishment of MH web-pages. The Armed Forces need an effective MH service

    Oxygen is one of the most important variables measured in oceanography, influenced both by physical and biological factors. During the OSMOSIS project, 7 Seagliders were used in 3 subsequent missions to measure a multidisciplinary suite of parameters at high frequency in the top 1000 m of the water column for one year, from September 2012 to September 2013. The gliders were deployed at the PAP time series station (nominally at 49° N 16.5° W) and surveyed the area following a butterfly-shaped path. Oxygen concentration was measured by Aanderaa optodes and calibrated using ship CTD O2 profiles during 5 deployment and recovery cruises, which were in turn calibrated by Winkler titration of discrete samples. The oxygen-rich mixed layer deepens in fall and winter and gets richer in oxygen when the temperature decreases. The spring bloom did not happen as expected, but instead the presence of a series of small blooms was measured throughout spring and early summer. During the summer the mixed layer become very shallow and oxygen concentrations decreased. A Deep Oxygen Maximum (DOM) developed along with a deep chlorophyll maximum during the summer and was located just below the mixed layer . At this depth, phytoplankton had favourable light and nutrient conditions to grow and produce oxygen, which was not subject to immediate outgassing. The oxygen concentration in the DOM was not constant, but decreased, then increased again until the end of the mission. Intrusions of oxygen rich water are also visible throughout the mission. These are probably due to mesoscale events through the horizontal transport of oxygen and/or nutrients that can enhance productivity, particularly at the edge of the fronts. We calculate net community production (NCP) by analysing the variation in oxygen with time. Two methods have been proposed. The classical oxygen budget method assumes that changes in oxygen are due to the sum of air-sea flux, isopycnal advection, diapycnal mixing and NCP. ERA

    Although the standard treatment of acute appendicitis (AA) consists of an early appendectomy, there has recently been both an interest and an increase in the use of antibiotic therapy as the primary treatment for uncomplicated AA. However, the use of antibiotic therapy in the treatment of uncomplicated AA is still controversial. The APPAC trial is a randomized prospective controlled, open label, non-inferiority multicenter trial designed to compare antibiotic therapy (ertapenem) with emergency appendectomy in the treatment of uncomplicated AA. The primary endpoint of the study is the success of the randomized treatment. In the antibiotic treatment arm successful treatment is defined as being discharged from the hospital without the need for surgical intervention and no recurrent appendicitis during a minimum follow-up of one-year (treatment efficacy). Treatment efficacy in the operative treatment arm is defined as successful appendectomy evaluated to be 100%. Secondary endpoints are post-intervention complications, overall morbidity and mortality, the length of hospital stay and sick leave, treatment costs and pain scores (VAS, visual analoque scale). A maximum of 610 adult patients (aged 18-60 years) with a CT scan confirmed uncomplicated AA will be enrolled from six hospitals and randomized by a closed envelope method in a 1:1 ratio either to undergo emergency appendectomy or to receive ertapenem (1 g per day) for three days continued by oral levofloxacin (500 mg per day) plus metronidazole (1.5 g per day) for seven days. Follow-up by a telephone interview will be at 1 week, 2 months and 1, 3, 5 and 10 years; the primary and secondary endpoints of the trial will be evaluated at each time point. The APPAC trial aims to provide level I evidence to support the hypothesis that approximately 75-85% of patients with uncomplicated AA can be treated with effective antibiotic therapy avoiding unnecessary appendectomies and the related operative morbidity, also resulting

    In this paper, the optimal strategy for a single product single supplier inventory system with random demand is analyzed by using robust predictive control with additive random parameter. We formulate the dynamical system of this system as a linear state space with additive random parameter. To determine and analyze the optimal strategy for the given inventory system, we use robust predictive control approach which gives the optimal strategy i.e. the optimal product volume that should be purchased from the supplier for each time period so that the expected cost is minimal. A numerical simulation is performed with some generated random inventory data. We simulate in MATLAB software where the inventory level must be controlled as close as possible to a set point decided by us. From the results, robust predictive control model provides the optimal strategy i.e. the optimal product volume that should be purchased and the inventory level was followed the given set point.

    To test the hypotheses that community-dwelling veterans with spinal cord injury (SCI) who receive the Wheelchair Skills Training Program (WSTP) in their own environments significantly improve their manual wheelchair-skills capacity, retain those improvements at one year and improve participation in comparison with an Educational Control (EC) group. We carried out a randomized controlled trial, studying 106 veterans with SCI from three Veterans Affairs rehabilitation centers. Each participant received either five one-on-one WSTP or EC sessions 30-45 minutes in duration. The main outcome measures were the total and subtotal percentage capacity scores from the Wheelchair Skills Test 4.1 (WST) and Craig Handicap Assessment and Reporting Technique (CHART) scores. Participants in the WSTP group improved their total and Advanced-level WST scores by 7.1% and 30.1% relative to baseline (p advanced and total wheelchair skills capacity of experienced community-dwelling veterans with SCI but has only a small impact on participation.

    To describe the proportion of people with Type 2 diabetes living in Scotland who meet eligibility criteria for inclusion in several large randomized controlled trials of glycaemic control to inform physicians and guideline developers about the generalizibility of trial results. A literature review was performed to identify large trials assessing the impact of glycaemic control on risk of macrovascular disease. Inclusion and exclusion criteria from each trial were applied to data on the population of people with a diagnosis of Type 2 diabetes living in Scotland in 2008 (n = 180,590) in a population-based cross-sectional study and the number and proportion of people eligible for each trial was determined. Seven trials were identified. The proportion of people with Type 2 diabetes who met the eligibility criteria for the trials ranged from 3.5 to 50.7%. Trial participants were younger at age of diagnosis of diabetes and at time of trial recruitment than in the Scottish study population. The application of upper age criteria excluded the largest proportion of patients, with up to 39% of people with Type 2 diabetes ineligible for a trial with the most stringent criteria based on age alone. We found that many of the large trials of glycaemic control among people with Type 2 diabetes have limited external validity when applied to a population-based cohort of people with Type 2 diabetes. In particular, the age distribution of trial participants often does not reflect that of people with Type 2 diabetes in a contemporary British population. © 2012 The Authors.

    Diarrhea's impact on childhood morbidity can be reduced by administering oral rehydration solution (ORS) with zinc; challenges to wider use are changing health-seeking behavior and ensuring access. We conducted a randomized controlled trial to increase ORS plus zinc uptake in rural Myanmar. Village tracts, matched in 52 pairs, were randomized to standard ORS access vs. a social franchising program training community educators and supplying ORS plus zinc. Intervention and control communities were comparable on demographics, prevalence of diarrhea and previous use of ORS. One year after randomization, ORS plus zinc use was 13.7% in the most recent case of diarrhea in intervention households compared with 1.8% in control households (p franchising increased optimal treatment of childhood diarrhea in rural Myanmar.

    Sports- and fitness-themed video games using motion controllers have been found to produce physical activity. It is possible that motion controllers may also enhance energy expenditure when applied to more sedentary games such as action games. Young adults (N = 100) were randomized to play three games using either motion-based or traditional controllers. No main effect was found for controller or game pair (P > .12). An interaction was found such that in one pair, motion control (mean [SD] 0....

    The epilepsy treatment gap is largest in resource-poor countries. We evaluated the efficacy of a 1-day health education program in a rural area of Kenya. The primary outcome was adherence to antiepileptic drugs (AEDs) as measured by drug levels in the blood, and the secondary outcomes were seizure frequency and Kilifi Epilepsy Beliefs and Attitudes Scores (KEBAS). Seven hundred thirty-eight people with epilepsy (PWE) and their designated supporter were randomized to either the intervention (education) or nonintervention group. Data were collected at baseline and 1 year after the education intervention was administered to the intervention group. There were 581 PWE assessed at both time points. At the end of the study, 105 PWE from the intervention group and 86 from the nonintervention group gave blood samples, which were assayed for the most commonly used AEDs (phenobarbital, phenytoin, and carbamazepine). The proportions of PWE with detectable AED levels were determined using a standard blood assay method. The laboratory technicians conducting the assays were blinded to the randomization. Secondary outcomes were evaluated using questionnaires administered by trained field staff. Modified Poisson regression was used to investigate the factors associated with improved adherence (transition from nonoptimal AED level in blood at baseline to optimal levels at follow-up), reduced seizures, and improved KEBAS, which was done as a post hoc analysis. This trial is registered in ISRCTN register under ISRCTN35680481. There was no significant difference in adherence to AEDs based on detectable drug levels (odds ratio [OR] 1.46, 95% confidence interval [95% CI] 0.74-2.90, p = 0.28) or by self-reports (OR 1.00, 95% CI 0.71-1.40, p = 1.00) between the intervention and nonintervention group. The intervention group had significantly fewer beliefs about traditional causes of epilepsy, cultural treatment, and negative stereotypes than the nonintervention group. There was no

    Objective: To demonstrate lower limb angiography results of peripheral arterial disease (PAD) in diabetics and evaluate one-year curative effect after interventional therapy. Methods: Lower limb angiography results and the efficiency of interventional therapy for 44 limbs with PAD in 38 diabetics were retrospectively analyzed. Post-treatment clinical manifestations, signs and ankle-brachial-index (ABI) at 1 week, 1 month, 3 months, 6 months and 12 months were compared with those before treatment. Clinical evaluation was divided into four grades: apparent, effective, ineffective and deterioration. Efficiency = (apparent + effective) / total cases × 100%. ABI was compared using analysis of variance. Results: Lower limb angiography revealed multi-branch lesions, with multi-segmental stenoses or obstructions. Lesions involved both above- and below-the-knee arteries in 25 limbs (56.8%), only above-the-knee arteries in 3 limbs (6.8%) and only below-the-knee arteries in 16 limbs (36.4%). In the limbs only with below-the-knee arterial lesions, the involved artery branches were one in one limb (2.3%), two in six limbs (13.6%) and three in nine limbs (20.5%), respectively. The technical success rate of percutaneous transluminal angioplasty (PTA) was 91.4% (53/58) for diseased below-the-knee arteries. Among the 12 cases with foot and ankle ulcers, ulcers healed within 3 months in 9 cases; however, the other three cases suffered below-the-ankle (in one case) or below-the-knee amputation (in two cases) within 6 months. Four cases with gangrene suffered below-the-knee amputation within one month after PTA. The amputation rate was 15.9% (7/44). At 1 week, 1, 3, 6 and 12 months after PTA, the effective rates were 79.6% (35/44), 83.3% (30/36), 85.7% (24/28), 85.0% (17/20) and 81.3% (13/16), respectively; ABI values were 0.86±0.10, 0.85±0.10, 0.83±0.11, 0.79±0.12 and 0.75±0.12, respectively. Compared with pie-PTA ABI value (0.53±0.20), post-PTA ABI value was significant
