    OBJECTIVE. To test the effectiveness of an educational intervention aimed at improving mental health knowledge and skills in occupational therapists working with older rehabilitation patients. METHOD. The DVD-format educational intervention was evaluated using a two-group randomized wait-list control design. Occupational therapists (n = 75) completed a 32-item knowledge questionnaire at three time points. Patient charts were reviewed (n = 960) at 3 months before and 3 and 6 months after DVD training to evaluate clinical practice change. RESULTS. A two-way analysis of variance showed knowledge scores increased significantly for both groups after DVD training. A significant Group × Time interaction and significant main effects for time and group were found. Chart review data also showed significant increases in desired clinical behaviors in both groups after training. The greatest single item of clinical practice change was use of a standardized depression screen. CONCLUSION. DVD-based training can significantly improve mental health practice.

    Since the introduction of cochlear implantation, researchers have considered children's communication and educational success before and after implantation. Therefore, the present study aimed to compare auditory, speech, and language development scores following one-sided cochlear implantation between two groups of prelingual deaf children educated through either auditory-only (unisensory) or auditory-visual (bisensory) modes. A randomized controlled trial with a single-factor experimental design was used. The study was conducted in the Instruction and Rehabilitation Private Centre of Hearing Impaired Children and their Family, called Soroosh in Shiraz, Iran. We assessed 30 Persian deaf children for eligibility and 22 children qualified to enter the study. They were aged between 27 and 66 months old and had been implanted between the ages of 15 and 63 months. The sample of 22 children was randomly assigned to two groups: auditory-only mode and auditory-visual mode; 11 participants in each group were analyzed. In both groups, the development of auditory perception, receptive language, expressive language, speech, and speech intelligibility was assessed pre- and post-intervention by means of instruments which were validated and standardized in the Persian population. No significant differences were found between the two groups. The children with cochlear implants who had been instructed using either the auditory-only or auditory-visual modes acquired auditory, receptive language, expressive language, and speech skills at the same rate. Overall, spoken language significantly developed in both the unisensory group and the bisensory group. Thus, both the auditory-only mode and the auditory-visual mode were effective. Therefore, it is not essential to limit access to the visual modality and to rely solely on the auditory modality when instructing hearing, language, and speech in children with cochlear implants who are exposed to spoken language both at home and at school

    Streptococcus pyogenes (Group A Streptococcus, GAS) is an important human commensal that occasionally causes localized infections and less frequently causes severe invasive disease with high mortality rates. How GAS regulates expression of factors used to colonize the host and avoid immune responses remains poorly understood. Intercellular communication is an important means by which bacteria coordinate gene expression to defend against host assaults and competing bacteria, yet no conserved cell-to-cell signaling system has been elucidated in GAS. Encoded within the GAS genome are four rgg-like genes, two of which (rgg2 and rgg3) have no previously described function. We tested the hypothesis that rgg2 or rgg3 rely on extracellular peptides to control target-gene regulation. We found that Rgg2 and Rgg3 together tightly regulate two linked genes encoding new peptide pheromones. Rgg2 activates transcription of and is required for full induction of the pheromone genes, while Rgg3 plays an antagonistic role and represses pheromone expression. The active pheromone signals, termed SHP2 and SHP3, are short and hydrophobic (DI[I/L]IIVGG), and, though highly similar in sequence, their ability to disrupt Rgg3-DNA complexes were observed to be different, indicating that specificity and differential activation of promoters are characteristics of the Rgg2/3 regulatory circuit. SHP-pheromone signaling requires an intact oligopeptide permease (opp) and a metalloprotease (eep), supporting the model that pro-peptides are secreted, processed to the mature form, and subsequently imported to the cytoplasm to interact directly with the Rgg receptors. At least one consequence of pheromone stimulation of the Rgg2/3 pathway is increased biogenesis of biofilms, which counteracts negative regulation of biofilms by RopB (Rgg1). These data provide the first demonstration that Rgg-dependent quorum sensing functions in GAS and substantiate the role that Rggs play as peptide receptors across the

    Full Text Available BACKGROUND: Substance use during sex is associated with sexual risk behavior among men who have sex with men (MSM, and MSM continue to be the group at highest risk for incident HIV in the United States. The objective of this study is to test the efficacy of a group-based, cognitive-behavioral intervention to reduce risk behavior of substance-using MSM, compared to a randomized attention-control group and a nonrandomized standard HIV-testing group. METHODS AND FINDINGS: Participants (n = 1,686 were enrolled in Chicago, Los Angeles, New York City, and San Francisco and randomized to a cognitive-behavioral intervention or attention-control comparison. The nonrandomized group received standard HIV counseling and testing. Intervention group participants received six 2-h group sessions focused on reducing substance use and sexual risk behavior. Attention-control group participants received six 2-h group sessions of videos and discussion of MSM community issues unrelated to substance use, sexual risk, and HIV/AIDS. All three groups received HIV counseling and testing at baseline. The sample reported high-risk behavior during the past 3 mo prior to their baseline visit: 67% reported unprotected anal sex, and 77% reported substance use during their most recent anal sex encounter with a nonprimary partner. The three groups significantly (p0.05 from each other at 3-, 6-, and 12-mo follow-up. Outcomes for the 2-arm comparisons were not significantly different at 12-mo follow-up (e.g., unprotected anal sex, odds ratio = 1.14, confidence interval = 0.86-1.51, nor at earlier time points. Similar results were found for each outcome variable in both 2- and 3-arm comparisons. CONCLUSIONS: These results for reducing sexual risk behavior of substance-using MSM are consistent with results of intervention trials for other populations, which collectively suggest critical challenges for the field of HIV behavioral interventions. Several mechanisms may contribute to

    The mitochondrial DNA (mtDNA) control region (198- to 598-bp) of four ancient Canis specimens (two Canis mandibles, a cranium, and a first phalanx) was examined, and each specimen was genetically identified as Japanese wolf. Two unique nucleotide substitutions, the 78-C insertion and the 482-G deletion, both of which are specific for Japanese wolf, were observed in each sample. Based on the mtDNA sequences analyzed, these four specimens and 10 additional Japanese wolf samples could be classified into two groups- Group A (10 samples) and Group B (4 samples)-which contain or lack an 8-bp insertion/deletion (indel), respectively. Interestingly, three dogs (Akita-b, Kishu 25, and S-husky 102) that each contained Japanese wolf-specific features were also classified into Group A or B based on the 8-bp indel. To determine the origin or ancestor of the Japanese wolf, mtDNA control regions of ancient continental Canis specimens were examined; 84 specimens were from Russia, and 29 were from China. However, none of these 113 specimens contained Japanese wolf-specific sequences. Moreover, none of 426 Japanese modern hunting dogs examined contained these Japanese wolf-specific mtDNA sequences. The mtDNA control region sequences of Groups A and B appeared to be unique to grey wolf and dog populations.

    Parkinson's disease (PD) is the second most common neurodegenerative disorder in developed countries. There is an increasing interest in the use of mindfulness-related interventions in the management of patients with a chronic disease. In addition, interventions that promote personal control, stress-management and other lifestyle factors, such as diet and exercise, assist in reducing disability and improving quality of life in people with chronic illnesses. There has been little research in this area for people with PD. A prospective mixed-method randomised clinical trial involving community living adults with PD aged benefits of, and barriers to, the uptake of the intervention. This protocol has received ethics approval from the Monash University Human Research Ethics Committee project number CF11/2662-2011001553. This is the first research of its kind in Australia involving a comprehensive, lifestyle-based programme for people with PD and has the potential to involve a broader range of providers than standard care. The findings will be disseminated through peer reviewed journals, primary care conferences in Australia as well as abroad and through the Parkinson's community.

    Levitas et al. (2006) showed in a cohort study that hypnosis during embryo transfer (ET) increased pregnancy ratio by 76%. In order to evaluate hypnosis during ET in a general population, the authors performed a randomized prospective controlled study comparing diazepam (usual premedication) administered before ET plus muscle relaxation versus hypnosis plus placebo in 94 patients. Additionally, the authors studied anxiety pre and post ET. Anxiety scores were not different in the two groups before and after ET. No difference in pregnancy and birth ratio was found in the two groups. Hypnosis during ET is as effective as diazepam in terms of pregnancy ratio and anxiolytic effects, but with fewer side effects and should be routinely available.

    To observe the effect on intervention of sub-health with pestle needle (Chuzhen). Randomized controlled trail was adopted for this research. One hundred and fifty-three cases were randomly divided into two groups of a Chuzhen group (79 cases) and a massage group (74 cases). Acupoint of Bazhen (Baihui Bazhen, Shendao Bazhen, Zhiyang Bazhen, Mingmen Bazhen, Yaoyangguan Bazhen), Hechelu on the head, the neck and the lumbar area were adopted in Chuzhen group. While regular whole-body massage was applied in the massage group. The human sub-health score, the cornell medical index (CMI) and thermal texture maps system (TTM) technology of the two groups before and after the intervention were observed. 1) After treatment, sub-health condition score, the CMI score, the M-R score and the TTM index were all increased in both groups (all P0.05). 3) The sub-health condition score in Chuzhen group was higher than that in the massage group (P<0.01). Chuzhen therapy has definite effect on intervention of sub-health, which is better than regular general massage.

    2013-01-01

    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.

    To observe the therapeutic effect of acpuncture treatment for chronic fatigue syndrome (CFS). Nighty cases of CFS were randomly divided into an observation group and a control group, 45 cases in each group. The observation group was treated with acupunture at Renying (ST 9), Fengfu (GV 16), Baihui (GV 20); the control group was treated with 250 mL 5% Glucose injectio combined with 20 mL Shenmai injectio. Fatigue Scale (FS) was used to compare the scores between the two groups after treatment. The total scores in the observation group were 9.37 +/- 2.33 and 5.41 +/- 1.96 before and after treatment respectively, and in the control group, they were 9.08 +/- 2.27 and 7.34 +/- 2.03 respectively. FS brainwork integral, physical fatigue integral, and total integral all decreased after treatment in two groups (all P < 0.001), and it decreased much more obviously in the observation group (P < 0.05, P < 0.01). Both of the acpuncture treatment and Shenmai injectio are able to decrease fatigue scale score, improve the fatigue symptoms of CFS patients, and the effect of acupucture treatment is obviously superior to that of Shenmai injectio.

    The problem of open-loop dynamical control of generic open quantum systems is addressed. In particular, I focus on the task of effectively switching off environmental couplings responsible for unwanted decoherence and dissipation effects. After revisiting the standard framework for dynamical decoupling via deterministic controls, I describe a different approach whereby the controller intentionally acquires a random component. An explicit error bound on worst-case performance of stochastic decoupling is presented.

    TRIAL DESIGN: To compare the difference in pain score during flexible cystoscopy between patients undergoing the procedure with plain lubricating gel  only and plain gel with diclofenac suppository in a randomized control trial. METHODS:  A total of 60 male patients with an indication of flexible cystoscopy were enrolled in a prospective, randomized controlled study. Patients were randomized in two groups. In group “A”, patients received diclofenac suppository one hour prior to the procedure while group “B” did not receive diclofenac suppository. Both groups received 10 ml of intra-urethral  plain gel for lubrication during flexible cystoscopy. Pain score was recorded immediately after the procedure using the visual analogue scale (VAS). Pre- and post-procedure pulse rate and systolic blood pressure was also recorded. Statistical analyses were performed using chi-square test and student t-test. Regression analysis was performed to address the confounding variables. RESULTS: Both groups were comparable for variables including age, duration of procedure, level of operating surgeon and indication of procedure. Most common indication for flexible cystoscopy was removal of double J stent. There was a statistically significant difference in the mean pain score between two groups ( p = 0.012).  The difference in post-procedure mean pulse rate in the two groups was statistically significant ( p= 0.01) however there was no difference observed in mean post procedure systolic blood pressure. Regression analysis showed that none of the confounding variables were significantly affecting pain perception. CONCLUSIONS: Intra rectal diclofenac suppository is simple and effective pre-emptive analgesia. We recommend its routine use during flexible cystoscopy for better pain control. PMID:28299180

    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 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.

    In this paper, we investigate the controllability of impulsive differential systems with random coefficients. Impulsive differential systems with random coefficients are a different stochastic model from stochastic differential equations. Sufficient conditions of sample controllability for impulsive differential systems with random coefficients are obtained by using random Sadovskii's fixed-point theorem. Finally, an example is given to illustrate our results.

    To test the potential benefit of extending cognitive-behavioral therapy (CBT) relative to not extending CBT on long-term abstinence from smoking. Two-group parallel randomized controlled trial. Patients were randomized to receive non-extended CBT (n = 111) or extended CBT (n = 112) following a 26-week open-label treatment. Community clinic in the United States. A total of 219 smokers (mean age: 43 years; mean cigarettes/day: 18). All participants received 10 weeks of combined CBT + bupropion sustained release (bupropion SR) + nicotine patch and were continued on CBT and either no medications if abstinent, continued bupropion + nicotine replacement therapy (NRT) if increased craving or depression scores, or varenicline if still smoking at 10 weeks. Half the participants were randomized at 26 weeks to extended CBT (E-CBT) to week 48 and half to non-extended CBT (no additional CBT sessions). The primary outcome was expired CO-confirmed, 7-day point-prevalence (PP) at 52- and 104-week follow-up. Analyses were based on intention-to-treat. PP abstinence rates at the 52-week follow-up were comparable across non-extended CBT (40%) and E-CBT (39%) groups [odds ratio (OR) = 0.99; 95% confidence interval (CI) = 0.55, 1.78]. A similar pattern was observed across non-extended CBT (39%) and E-CBT (33%) groups at the 104-week follow-up (OR = 0.79; 95% CI= 0.44, 1.40). Prolonging cognitive-behavioral therapy from 26 to 48 weeks does not appear to improve long-term abstinence from smoking. © 2017 Society for the Study of Addiction.

    Clinicians, patients, governments, third-party payers, and the public take for granted that diagnostic tests are accurate, safe and effective. However, we may be seriously misled if we are relying on robust study design to ensure accurate, safe, and effective diagnostic tests. Properly conducted, randomized controlled trials are the gold standard for assessing the effectiveness and safety of interventions, yet are rarely conducted in the assessment of diagnostic tests. Instead, diagnostic cohort studies are commonly performed to assess the characteristics of a diagnostic test including sensitivity and specificity. While diagnostic cohort studies can inform us about the relative accuracy of an experimental diagnostic intervention compared to a reference standard, they do not inform us about whether the differences in accuracy are clinically important, or the degree of clinical importance (in other words, the impact on patient outcomes). In this commentary we provide the advantages of the diagnostic randomized controlled trial and suggest a greater awareness and uptake in their conduct. Doing so will better ensure that patients are offered diagnostic procedures that will make a clinical difference.

    The aim was to conduct a pragmatic randomized controlled trial (RCT) to evaluate two parenting programmes designed for adopters of children late placed from care. Adoptive parents, with children between 3 and 8 years who were screened to have serious behavioural problems early in the placement, participated in home-based, manualized, parenting programmes delivered by trained and supervised family social workers. The adopters who agreed to join the study were randomly allocated to one of two parenting interventions or to a "services as usual" group. Baseline, immediate post-intervention and six-month follow-ups were assessed using questionnaires and adopter interviews. No cases were lost to follow-up at any point and satisfaction was high with both parenting interventions. At the six-month follow-up, a significant difference (p parenting" in favour of the intervention group (Effect Size d = 0.7). Negative parenting approaches were reduced in the intervention group. However, no significant differences in child problems were found between the intervention groups and control group, adjusting for baseline scores. Costs analysis showed that a relatively modest investment in post-adoption support would be well spent in improving adopters' satisfaction with parenting in the intervention group compared to the routine service group.

    Full Text Available Background. Pentoxifylline is a nonspecific phosphodiesterase inhibitor with anti-inflammatory properties. Human studies have proved its antiproteinuric effect in patients with glomerular diseases, but this study was designed to assess the effects of add-on pentoxifylline to available treatment on reduction of microalbuminuria in diabetic patients without glomerular diseases. Methods. In a double-blind placebo-controlled, randomized study we evaluated the influence of pentoxifylline on microalbuminuria in type 2 diabetic patients. 40 diabetic patients with estimated glomerular filtration rate (eGFR of more than 60 mL/min/1.73 m2 in eight weeks and microalbuminuria were randomized to two groups which will receive pentoxifylline 1200 mg/day or placebo added to regular medications for 6 months. albuminuria; eGFR was evaluated at three- and six-month follow-up period. Results. Baseline characteristics were similar between the two groups. At six months, the mean estimated GFR and albuminuria were not different between two groups at 3- and 6-month follow-up. Trend of albumin to creatinine ratio, systolic and diastolic blood pressure, and eGFR in both groups were decreased, but no significant differences were noted between two groups (P value > 0.05. Conclusion. Pentoxifylline has not a significant additive antimicroalbuminuric effect compared with placebo in patients with type 2 diabetes with early stage of kidney disease; however, further clinical investigations are necessary to be done.

    Full Text Available A lifelong gluten-free diet (GFD is mandatory for celiac disease (CD but has poor compliance, justifying novel strategies. 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. On day 90, 0 controls and 14 patients in the experimental group completed the challenge with no variation of antitransglutaminase IgA (=0.63, Marsh-Oberhuber grading (=0.08, or intestinal IFN-γ mRNA (>0.05. Creatinine clearance did not vary after 90 days of treatment (=0.46. In conclusion, transamidated gluten reduced the number of clinical relapses in challenged patients with no changes of baseline values for serological/mucosal CD markers and an unaltered kidney function.

    Full Text Available Objective: Emotional disturbances are commonly experienced by cancer patients. The aim of this study was to determine the effectiveness of certain Pranayama techniques on the emotional aspects such as impatience, worry, anxiety, and frustration among breast cancer patients undergoing radiation therapy in India. Methods: The study was conducted as a randomized controlled trial. Patients were recruited when they were seeking radiation therapy for breast cancer. They were allocated into two groups using block randomization technique. The experimental group performed Pranayama along with radiation therapy, whereas the control group received only routine care. Results: Emotional aspects of the two groups were compared at the end of the treatment. Mann-Whitney U-test was used for comparison as the data were not following normality. It showed a significant difference between the two groups with the group who performed Pranayama showing a lesser mean score for these negative emotions. Conclusions: Pranayama might help in controlling the negative emotions likely to be faced by breast cancer patients, and it can be used as a supportive therapy for breast cancer patients receiving radiation therapy.

    Deformational plagiocephaly (DP) occurs frequently in otherwise healthy infants. Many infants with DP undergo physiotherapy or helmet therapy, and ample treatment-related research is available. However, the possibility of preventing DP has been left with little attention. We sought to evaluate the effectiveness of intervention in the newborn's environment, positioning, and handling on the prevalence of DP at 3 months and to investigate the causal relationship between DP and cervical imbalance. We carried out a randomized controlled trial, with healthy newborns randomized into two groups at birth. All families received standard positioning instructions to prevent SIDS. Additionally, the intervention group received detailed instructions regarding the infant's environment, positioning, and handling, with the goal of creating a nonrestrictive environment that promotes spontaneous physical movement and symmetrical motor development. Two- and three-dimensional photogrammetry served to assess cranial shape and goniometry to measure cervical motion. At 3 months, the prevalence of DP was lower in the intervention group in both 2D (11 vs 31 %) and 3D analyses (15 vs 33 %), and the asymmetry was milder in the intervention group. Infants with DP at follow-up had also developed more torticollis. An early educational intervention reduces the prevalence and severity of DP at 3 months. •Deformational plagiocephaly, often with associated torticollis, is common in healthy infants. •Parental education is frequently recommended for preventing deformational plagiocephaly, although information regarding the effectiveness of preventive strategies is scarce. •Early parent guidance effectively reduces the prevalence and severity of DP and improves the cervical range of motion at three months. •Educating both parents and professionals about proper infant positioning on a national scale could help minimize public healthcare costs.

    Randomized controlled trials (RCTs) are the hallmark of evidence-based medicine and form the basis for translating research data into clinical practice. This review summarizes commonly applied designs and quality indicators of RCTs to provide guidance in interpreting and critically evaluating clinical research data. It further reflects on the principle of equipoise and its practical applicability to clinical science with an emphasis on critical care and neurological research. We performed a review of educational material, review articles, methodological studies, and published clinical trials using the databases MEDLINE, PubMed, and ClinicalTrials.gov. The most relevant recommendations regarding design, conduction, and reporting of RCTs may include the following: 1) clinically relevant end points should be defined a priori, and an unbiased analysis and report of the study results should be warranted, 2) both significant and nonsignificant results should be objectively reported and published, 3) structured study design and performance as indicated in the Consolidated Standards of Reporting Trials statement should be employed as well as registration in a public trial database, 4) potential conflicts of interest and funding sources should be disclaimed in study report or publication, and 5) in the comparison of experimental treatment with standard care, preplanned interim analyses during an ongoing RCT can aid in maintaining clinical equipoise by assessing benefit, harm, or futility, thus allowing decision on continuation or termination of the trial.

The controlled clinical trial was conducted in 2014 at Shahid Hasheminejhad Hospital, Iran, and comprised preterm neonatal children in the neonatal intensive care unit. The newborns were divided into two groups of massage and control via random allocation. The children in the control group received the routine therapy whereas those in the massage group underwent the same four days of routine plus 20 minutes of massage twice a day. The transcutaneous bilirubin and the number of excretions of the newborns were noted from the first to the fourth day of the intervention and results were compared between the two groups. There were 40 newborns in the study l 20(50%) each in the two groups. There was a significant difference in the number of times of defecation (p=0.002) and in the level of bilirubin (p=0.003) between the groups with those in the massage group having a higher number of defecations as well as a lower level of transcutaneous bilirubin. Through massage therapy the bilirubin level in preterm newborns can be controlled and a need for phototherapy can also be delayed.

    Full Text Available TRIAL DESIGN: To compare the difference in pain score during flexible cystoscopy between patients undergoing the procedure with plain lubricating gel  only and plain gel with diclofenac suppository in a randomized control trial. METHODS:  A total of 60 male patients with an indication of flexible cystoscopy were enrolled in a prospective, randomized controlled study. Patients were randomized in two groups. In group “A”, patients received diclofenac suppository one hour prior to the procedure while group “B” did not receive diclofenac suppository. Both groups received 10 ml of intra-urethral  plain gel for lubrication during flexible cystoscopy. Pain score was recorded immediately after the procedure using the visual analogue scale (VAS. Pre- and post-procedure pulse rate and systolic blood pressure was also recorded. Statistical analyses were performed using chi-square test and student t-test. Regression analysis was performed to address the confounding variables. RESULTS: Both groups were comparable for variables including age, duration of procedure, level of operating surgeon and indication of procedure. Most common indication for flexible cystoscopy was removal of double J stent. There was a statistically significant difference in the mean pain score between two groups (p = 0.012.  The difference in post-procedure mean pulse rate in the two groups was statistically significant (p= 0.01 however there was no difference observed in mean post procedure systolic blood pressure. Regression analysis showed that none of the confounding variables were significantly affecting pain perception. CONCLUSIONS: Intra rectal diclofenac suppository is simple and effective pre-emptive analgesia. We recommend its routine use during flexible cystoscopy for better pain control.

    We discuss the fundamental role that chaosity and randomness play in the determination of quality and efficiency of medical treatment. The statistical parameter of non-Markovity from non-equilibrium statistical physics of condensed matters is offered as a quantitative information measure of chaosity and randomness. The role of chaosity and randomness is determined by the phenomenological property, which includes quantitative informational measures of chaosity and randomness and pathology (disease) in a covariant form. Manifestations of the statistical informational behavior of chaosity and randomness are examined while analyzing the chaotic dynamics of RR intervals from human ECG's, the electric signals of a human muscle's tremor of legs in a normal state and at Parkinson disease, the electric potentials of the human brain core from EEG's during epileptic seizure and a human hand finger tremor in Parkinson's disease. The existence of the above stated informational measure allows to introduce the quantitative factor of the quality of treatment. The above-stated examples confirm the existence of new phenomenological property, which is important not only for the decision of medical problems, but also for the analysis of the wide range of problems of physics of complex systems of life and lifeless nature.

    Randomized assignment of treatment excludes reverse causation and selection bias and, in sufficiently large studies, effectively prevents confounding. Well-implemented blinding prevents measurement bias. Studies that include these protections are called randomized, blinded clinical trials and, when conducted with sufficient numbers of patients, provide the most valid results. Although conceptually straightforward, design of clinical trials requires thoughtful trade-offs among competing approaches-all of which influence the number of patients required, enrollment time, internal and external validity, ability to evaluate interactions among treatments, and cost.

    Failure in complete healing of the wound is one of the probable complications of cesarean. The present study aimed to determine the effectiveness of dressing with aloe vera gel in healing of cesarean wound. This prospective randomized double-blind clinical trial was conducted on 90 women who had undergone cesarean operation in Amir-al-Momenin hospital (Gerash, Iran). The participants were randomly divided into two groups each containing 45 patients. In one group, the wound was dressed with aloe vera gel, while simple dressing was used in the control group. Wound healing was assessed 24 hours and 8 days after the cesarean operation using REEDA scale. The data were analyzed through Chi-square and t-test. The participants' mean age was 27.56±4.20 in the aloe vera group and 26.62±4.88 in the control group, but the difference was not statistically significant. However, a significant difference was found between the two groups concerning body mass index, heart rate, and systolic blood pressure (Paloe vera group and 35 ones in the control group had obtained a zero score 24 hours after the operation. These measures were respectively obtained as 42 and 41eight days after the operation. According to the findings of this study, the women are recommended to be informed regarding the positive effects of dressing with aloe vera gel.

    Acute postoperative pain control in children is an essential component of postoperative care, particularly in daycare procedures. Giving patients continuous narcotic analgesics can be risky; however, a single dose may be sufficient. This study used a prospective, randomized controlled design and was conducted at the Pediatric Surgery Unit, Services Hospital, Lahore. In total, 150 patients who underwent inguinal herniotomy (age range: 1-12 years) were randomly assigned to two groups: group A (nalbuphine) and group B (tramadol). Patients were given a single dose of either nalbuphine (0.2 mg/kg) or tramadol (2 mg/kg) immediately after surgery and pain was measured at 0, 1, 2, 4, and 8 h. The demographic characteristics were similar between the two groups. The mean pain score was lower in group A than in group B at 0 and 1 h (P tramadol, for postoperative pain management in children who have undergone daycare procedures.

    The evidence for the effectiveness of memory rehabilitation is inconclusive. The aim was to compare the effectiveness of two group memory rehabilitation programmes with a self-help group control. Single-blind randomized controlled trial. Participants with memory problems following traumatic brain injury, stroke or multiple sclerosis were recruited from community settings. Participants were randomly allocated, in cohorts of four, to compensation or restitution group treatment programmes or a self-help group control. All programmes were manual-based and comprised two individual and ten weekly group sessions. Memory functions, mood, and activities of daily living were assessed at baseline and five and seven months after randomization. There were 72 participants (mean age 47.7, SD 10.2 years; 32 men). There was no significant effect of treatment on the Everyday Memory Questionnaire (P = 0.97). At seven months the mean scores were comparable (restitution 36.6, compensation 41.0, self-help 44.1). However, there was a significant difference between groups on the Internal Memory Aids Questionnaire (P = 0.002). The compensation and restitution groups each used significantly more internal memory aids than the self-help group (P 0.05). There results show few statistically significant effects of either compensation or restitution memory group treatment as compared with a self-help group control. Further randomized trials of memory rehabilitation are needed.

Conclusion: This randomized control trial points towards the beneficial effect of yogic breathing program in preventing progression of cardiac neuropathy. This has important implications as cardiac autonomic neuropathy has been considered as one of the factors for sudden cardiac deaths.Keywords: comprehensive yogic breathing program, diabetes mellitus, cardiac autonomic function

  10. Delayed Random Walks: Modeling Human Posture Control

    Science.gov (United States)

    Ohira, Toru

    1998-03-01

    We consider a phenomenological description of a noisy trajectory which appears on a stabiliogram platform during human postural sway. We hypothesize that this trajectory arises due to a mixture of uncontrollable noise and a corrective delayed feedback to an upright position. Based on this hypothesis, we model the process with a biased random walk whose transition probability depends on its position at a fixed time delay in the past, which we call a delayed random walk. We first introduce a very simple model (T. Ohira and J. G. Milton, Phys.Rev.E. 52), 3277, (1995), which can nevertheless capture the rough qualitative features of the two--point mean square displacement of experimental data with reasonable estimation of delay time. Then, we discuss two approaches toward better capturing and understanding of the experimental data. The first approach is an extension of the model to include a spatial displacement threshold from the upright position below which no or only weak corrective feedback motion takes place. This can be incorporated into an extended delayed random walk model. Numerical simulations show that this extended model can better capture the three scaling region which appears in the two--point mean square displacement. The other approach studied the autocorrelation function of the experimental data, which shows oscillatory behavior. We recently investigated a delayed random walk model whose autocorrelation function has analytically tractable oscillatory behavior (T. Ohira, Phys.Rev.E. 55), R1255, (1997). We discuss how this analytical understanding and its application to delay estimation (T. Ohira and R. Sawatari, Phys.Rev.E. 55), R2077, (1997) could possibly be used to further understand the postural sway data.

    Understanding the sites of pharyngeal collapse is mandatory for surgical treatment decision-making in obstructive sleep-apnea-hypopnea syndrome patients. Drug-induced sleep endoscopy (DISE) allows for the direct observation of the upper airway during sedative-induced sleep. In order to re-create snoring and apnea patterns related to a spontaneous sleep situation, the authors used a target-controlled infusion (TCI) sleep endoscopy (DISE-TCI), comparing this technique to conventional DISE, in which sedation was reached by a manual bolus injection. The authors conducted a prospective, randomized, unicenter study. The apneic event observation and its correlation with pharyngeal collapse patterns is the primary endpoint; secondary endpoints are defined as stability and safety of sedation plans of DISE-TCI technique. From January 2009 to June 2009, 40 OSAHS patients were included in the study and randomized allocated in two groups: the bolus injection conventional DISE group and the DISE-TCI group. We recorded the complete apnea event at the oropharynx and hypopharynx levels in 4 patients of the conventional DISE group (20%) and in 17 patients of the DISE-TCI group (85%) (P DISE group because of severe desaturation that resulted from the first bolus of propofol (1 mg/kg) (P = 0.4872 ns). We recorded the instability of the sedation plan in 13 patients from the conventional DISE group (65%) and 1 patient from the DISE-TCI group (5%) (P = 0.0001). Our results suggest that the DISE-TCI technique should be the first choice in performing sleep endoscopy because of its increased accuracy, stability and safety.

    2013-01-01

    Full Text Available In networked control systems (NCSs, the presence of communication networks in control loops causes many imperfections such as random delays, packet losses, multipacket transmission, and packet disordering. In fact, random delays are usually the most important problems and challenges in NCSs because, to some extent, other problems are often caused by random delays. In order to compensate for random delays which may lead to performance degradation and instability of NCSs, it is necessary to establish the mathematical model of random delays before compensation. In this paper, four major delay models are surveyed including constant delay model, mutually independent stochastic delay model, Markov chain model, and hidden Markov model. In each delay model, some promising compensation methods of delays are also addressed.

    Full Text Available Despite some preliminary evidence, it is still largely unknown whether osteopathic manipulative treatment improves preterm clinical outcomes.The present multi-center randomized single blind parallel group clinical trial enrolled newborns who met the criteria for gestational age between 29 and 37 weeks, without any congenital complication from 3 different public neonatal intensive care units. Preterm infants were randomly assigned to usual prenatal care (control group or osteopathic manipulative treatment (study group. The primary outcome was the mean difference in length of hospital stay between groups.A total of 695 newborns were randomly assigned to either the study group (n= 352 or the control group (n=343. A statistical significant difference was observed between the two groups for the primary outcome (13.8 and 17.5 days for the study and control group respectively, p<0.001, effect size: 0.31. Multivariate analysis showed a reduction of the length of stay of 3.9 days (95% CI -5.5 to -2.3, p<0.001. Furthermore, there were significant reductions with treatment as compared to usual care in cost (difference between study and control group: 1,586.01€; 95% CI 1,087.18 to 6,277.28; p<0.001 but not in daily weight gain. There were no complications associated to the intervention.Osteopathic treatment reduced significantly the number of days of hospitalization and is cost-effective on a large cohort of preterm infants.

    Background Probiotics can alter the colonic microbiota and might improve bowel function. Objectives The aim of this study was to evaluate the effect of the consumption of yogurt, enriched with Bifidobacterium and Lactobacillus 4.8 × 1010 (CFU) on the symptoms of constipated pregnant women. Materials and Methods This triple-blind randomized controlled trial was conducted on 60 constipated pregnant women who were diagnosed by the ROME III criteria in Tabriz, Iran from December 2014 to July 2015. Participants were randomly put into two groups including the treatment and the control group through block randomization. The treatment group received 300 g of yogurt enriched with Bifidobacterium and Lactobacillus 4.8 × 1010 colony forming units (CFU) (n = 30) while the control group received conventional yogurt (n = 30) for 4 weeks. The defecation frequency, stool consistency, straining during defecation, sensation of anorectal obstruction, sensation of incomplete evacuation and manual manoeuvres to facilitate defecation were primary outcomes while the amount of defecation, stool colure, and quality of life were secondary outcomes. Results The frequency of defecation was increased from 2.1 (0.8) at baseline to 8.3 (4.4) in the probiotic yogurt group vs. 2.3 (0.7) at baseline to 8.1 (4.3) in the conventional yogurt group at the end of 4th week. These results were based on the repeated measure ANOVA test and there was no statistically significant difference between the two groups (mean difference: 0.1; Confidence Interval 95%: -1.4 to 1.7; P = 0.872). Constipation symptoms including straining, anorectal obstruction, manipulation to facilitate defecation, consistency of stool and color of stool were improved significantly (P probiotic and conventional yogurt can play a role in improving the symptoms of constipation during pregnancy.

    ;mild depression 8 - 20 points; moderate depression 21 - 35 points; severe depression > 35 points. ADL was assessed with Barthel index score (full mark 100 points). Higher points indicated better incidence and smaller dependence. Neurologic deficit score was made according to scoring criteria of neurologic deficit formulated in 1995 4th National Cerebrovascular Disease Conference: a score of 0 - 15 indicated a mild focal neurologic deficit, a score of 16 - 30 a moderate focal neurologic deficit, and a score of 31 - 45 a severe focal deficit.MAIN OUTCOME MEASURES: Scores of HAMD, ADL and neurologic deficit, and levels of plasma and platelet 5-HT of patients from 2 groups before, 2,4 and 8 weeks after test.RESULRS: Seventy-three of 90 randomized patients participated in the final analysis. In the treatment group,11 patients dropped out due to insufficient clinical response (n =4), somatic side effects (n =2), intervening medical illness (n =1), hypomania (n =3), and other reasons (n =2). In the placebo group, 6 patients existed due to insufficient clinical response (n =2), somatic side effects (n =1) and other reasons (n =3). ① Before treatment, there were no significant differences in scores of HAMD, DAL and neurologic deficit in patients between two groups (P > 0.05). After 8 weeks of treatment, the scores of HAMD, DAL and neurologic deficit in the treatment group were significantly different from those in the placebo group (12.6±5.3 vs. 16.3±3.7; 8.6±6.4 vs. 11.2±6.4; 60.4±12.5 vs. 52.3 ±13.5, P < 0.01). ② After 8 weeks of treatment, platelet 5-HT level of patients in the treatment group was significantly lower than that in the placebo group [(325.3 ±110.5) mg/L vs. (653.6±138.4) mg/L, P < 0.05], while there were no significant differences in plasma 5-HT between two groups (P > 0.05).CONCLUSION: Early fluoxetine treatment obviously retards PSD. The increase of platelet 5-HT level promotes the recovery of neurologic function.

    Background Inadequate blood pressure (BP) control is a frequent challenge in general practice. The objective of this study was to determine whether a color-coded BP booklet using a traffic light scheme (red, >180 mmHg systolic BP and/or >110 mmHg diastolic BP; yellow, >140–180 mmHg systolic BP or >90–110 mmHg diastolic BP; green, ≤140 mmHg systolic BP and ≤90 mmHg diastolic BP) improves BP control and adherence with home BP measurement. Methods In this two-group, randomized controlled trial, general practitioners recruited adult patients with a BP >140 mmHg systolic and/or >90 mmHg diastolic. Patients in the control group received a standard BP booklet and the intervention group used a color-coded booklet for daily home BP measurement. The main outcomes were changes in BP, BP control (treatment goal <140/90 mmHg), and adherence with home BP measurement after 6 months. Results One hundred and twenty-one of 137 included patients qualified for analysis. After 6 months, a significant decrease in systolic and diastolic BP was achieved in both groups, with no significant difference between the groups (16.1/7.9 mmHg in the intervention group versus 13.1/8.6 mmHg in the control group, P=0.3/0.7). BP control (treatment target <140/90 mmHg) was achieved significantly more often in the intervention group (43% versus 25%; P=0.037; number needed to treat of 5). Adherence with home BP measurement overall was high, with a trend in favor of the intervention group (98.6% versus 96.2%; P=0.1) Conclusion Color-coded BP self-monitoring significantly improved BP control (number needed to treat of 5, meaning that every fifth patient utilizing color-coded self-monitoring achieved better BP control after 6 months), but no significant between-group difference was observed in BP change. A markedly higher percentage of patients achieved BP values in the normal range. This simple, inexpensive approach of color-coded BP self-monitoring is user-friendly and applicable in primary care

    A randomized, active-controlled clinical trial was conducted to examine the effect of pulsed electromagnetic fields (PEMFs) on women with postmenopausal osteoporosis (PMO) in southwest China. Forty-four participants were randomly assigned to receive alendronate or one course of PEMFs treatment. The primary endpoint was the mean percentage change in bone mineral density of the lumbar spine (BMDL), and secondary endpoints were the mean percentage changes in left proximal femur bone mineral density (BMDF), serum 25OH vitamin D3 (25(OH)D) concentrations, total lower-extremity manual muscle test (LE MMT) score, and Berg Balance Scale (BBS) score. The BMDL, BMDF, total LE MMT score and BBS score were recorded at baseline, 5, 12, and 24 weeks. Serum concentrations of 25(OH)D were measured at baseline and 5 weeks. Using a mixed linear model, there was no significant treatment difference between the two groups in the BMDL, BMDF, total LE MMT score, and BBS score (P ≥ 0.05). For 25(OH)D concentrations, the effects were also comparable between the two groups (P ≥ 0.05) with the Mann-Whitney's U-test. These results suggested that a course of PEMFs treatment with specific parameters was as effective as alendronate in treating PMO within 24 weeks.

    Music played during endoscopic procedures may alleviate anxiety and improve patient acceptance of the procedure. A prospective randomized, controlled trial was undertaken to determine whether music decreases the requirement for midazolam during colonoscopy and makes the procedure more comfortable and acceptable. Patients undergoing elective colonoscopy between October 2003 and February 2004 were randomized to either not listen to music (Group 1; n=40) or listen to music of their choice (Group 2; n=38) during the procedure. All patients received intravenous midazolam on demand in aliquots of 2 mg each. The dose of midazolam, duration of procedure, recovery time, pain and discomfort scores and willingness to undergo a repeat procedure using the same sedation protocol were compared. Patients in Group 2 received significantly less midazolam than those in Group 1 (p=0.007). The pain score was similar in the two groups, whereas discomfort score was lower in Group 2 (p=0.001). Patients in the two groups were equally likely to be willing for a repeat procedure. Listening to music during colonoscopy helps reduce the dose of sedative medications and decreases discomfort experienced during the procedure.

    This study was designed to investigate the effect of N-acetylcysteine (NAC), as a potent and safe antioxidant, on inflammatory biomarkers of acute pyelonephritis in pediatric patients. Children (pyelonephritis were recruited in a randomized placebo-controlled trial. They were randomly allocated to 2 groups and recieved placebo or NAC effervescent tablets with daily dose based on their weight, for 5 days. The children were evaluated for serum procalcitonin level, leukocyte count, C-reactive protein (CRP), serum creatinine, and clinical symptoms on the 1st and the 5th days. Seventy patients, 35 in each group, with a mean age of 5.54 ± 3.10 years completed the study. There was no significant difference between the two groups in the amount of changes in procalcitonin levels after 5 days (P = .90). Within-group analysis confirmed CRP reduction in both groups (P < .001); however, between-group analysis did not show significant difference in CRP reductions, either (P = .65). No significant differences were found between the two groups in the day of resolving pyuria (P = .46), day of resolving bacteriuria (P = .81), or reductions in leukocyte count (P = .64) and neutrophil count (P = .49). A short period of NAC administration with the recommended doses could not lead to a significant decrease in inflammation biomarkers. Studies on higher doses and longer duration of NAC administration along with evaluation of the long-term effects of the intervention by tools such as renal scntigraphy are suggested.

    Full Text Available Abstract Background More than 70% of patients with depression who see their doctors experience insomnia. Insomnia treatment is a very important link for depression treatment. Furthermore, antidepression treatment is also important for depression insomnia. In acupuncture, LU-7 (Lie Que and KID-6 (Zhao Hai, which are two of the eight confluence points in meridian theory, are used as main points. An embedded needle technique is used, alternately, at two groups of points to consolidate the treatment effect. These two groups of points are BL-15 (Xin Shu with BL-23 (Shen Shu and BL-19 (Dan Shu with N-HN-54 (An Mian. The effectiveness of these optimized acupuncture formulas is well proven in the practice by our senior acupuncturists in Guangdong Provincial Hospital of TCM. This study has been designed to examine whether this set of optimized clinical formulas is able to increase the clinical efficacy of depression insomnia treatment. Methods/design In this randomized controlled multicenter trial, all the eligible participants are diagnosed with depression insomnia. All participants are randomly assigned to one of two groups in a ratio of 1:1 and receive either conventional acupuncture treatment or optimized acupuncture treatment. Patients are evaluated using the Pittsburgh Sleep Quality Index(PSQIand the Hamilton rating scale(HAMD for depression. The use of antidepression and hypnotics drugs is also considered. Results are obtained at the start of treatment, 1 and 2 months after treatment has begun, and at the end of treatment. The entire duration of the study will be approximately 36 months. Discussion A high quality of trial methodologies is utilized in the study, and the results may provide better evidence for the effectiveness of acupuncture as a treatment for depression insomnia. The optimized acupuncture formula has potential benefits in increasing the efficacy of treating depression insomnia. Trial registration The trial was registered in

    AIM: Ribavirin (RBV) shows a strong antiviral effect on hepatitis C virus when used in combination with interferon.However, RBV-induced anemia is a major problem in this therapy. It would be of great clinical importance to ameliorate the anemia without reducing the RBV dose.We report here that, Ninjinyoeito (NYT), a herbal medicine can reduce the RBV-induced anemia.METHODS: Twenty-three patients with chronic hepatitis C were treated with interferon alpha 2b plus RBV with (NYT group) or without (control group) NYT by a randomized selection. Eighteen patients completed the treatment schedule, and hemato-biochemical and virological effects were evaluated.RESULTS: There was no significant difference in biochemical and virological responses between the two groups. However, anemia was significantly reduced in the NYT group compared with the control group. The maximal decrease of Hb in the NYT group (2.59±1.10 g/dL)was significantly (P= 0.026) smaller than that in the control group (3.71±0.97 g/dL). There was no significant difference in serum glutathione peroxidase activity, serum RBV concentration, and Th1/Th2 balance between the two groups. There was no specific adverse effect in NYT administration.CONCLUSION: These results suggest that NYT could be used as a supportive remedy to reduce the RBV-induced anemia in the treatment of chronic hepatitis C.

    To assess the feasibility and effectiveness of a group memory rehabilitation programme combining compensation and restitution strategies. Randomized controlled trial. Community. People with multiple sclerosis who reported memory difficulties were recruited. A group memory rehabilitation programme, comprising ten 1.5-hour sessions, was compared with a waiting list control. The primary outcome was the Everyday Memory Questionnaire. Secondary outcomes included the General Health Questionnaire 28 and MS Impact Scale administered four and eight months after randomization. In addition, those in the intervention group gave feedback about the intervention. Forty-eight participants were recruited. They were aged 34-72 years (mean 54.3, SD 11.0) and 33 (69%) were women. There were no significant differences between the two groups on the Everyday Memory Questionnaire or MS Impact Scale (P > 0.05) at four or eight months after randomization. However, the intervention group reported significantly better mood than controls on the GHQ-28 at eight months (P = 0.04). Participants showed minimal benefit from the memory rehabilitation programme on quantitative measures but the intervention was well received, as indicated by positive feedback at the end of the intervention. There was no significant effect of the intervention on memory but there was a significant effect on mood. The results suggest a larger scale study is justified. © The Author(s) 2014.

    The objectives of this trial were to compare the effects of a holistic yoga program with the conventional exercise program in adolescent polycystic ovarian syndrome (PCOS). This was a prospective, randomized, active controlled trial. Ninety (90) adolescent (15-18 years) girls from a residential college in Andhra Pradesh who satisfied the Rotterdam criteria were randomized into two groups. The yoga group practiced a holistic yoga module, while the control group practiced a matching set of physical exercises (1 hour/day, for 12 weeks). Anti-müllerian hormone (AMH-primary outcome), luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, prolactin, body-mass index (BMI), hirsutism, and menstrual frequency were measured at inclusion and after 12 weeks. Mann-Whitney test on difference score shows that changes in AMH (Y=-2.51, C=-0.49, p=0.006), LH, and LH/FSH ratio (LH: Y=-4.09, C=3.00, p=0.005; LH/FSH: Y=-1.17, C=0.49, p=0.015) were significantly different between the two intervention groups. Also, changes in testosterone (Y=-6.01, C=2.61, p=0.014) and Modified Ferriman and Gallway (mFG) score (Y=-1.14, C=+0.06, p=0.002) were significantly different between the two groups. On the other hand, changes in FSH and prolactin postintervention were nonsignificantly different between the two groups. Also, body weight and BMI showed nonsignificantly different changes between the two groups, while changes in menstrual frequency were significantly different between the two groups (Y=0.89, C=0.49, p=0.049). A holistic yoga program for 12 weeks is significantly better than physical exercise in reducing AMH, LH, and testosterone, mFG score for hirsutism, and improving menstrual frequency with nonsignificant changes in body weight, FSH, and prolactin in adolescent PCOS.

    The aim of this study was to investigate the effect of incentive spirometer exercise (ISE) on pulmonary function and maximal phonation time (MPT) in children with spastic cerebral palsy (CP). Fifty children with CP were randomly assigned to two groups: the experimental group and the control group. Both groups underwent comprehensive rehabilitation therapy. The experimental group underwent additional ISE. The forced vital capacity (FVC), forced expiratory volume at one second (FEV₁), FEV₁/FVC ratio, peak expiratory flow (PEF), and MPT were assessed as outcome measures before and after 4 weeks of training. There were significant improvements in FVC, FEV₁, PEF, and MPT in the experimental group, but not in the control group. In addition, the improvements in FVC, FEV₁, and MPT were significantly greater in the experimental group than in the control group. The results of this randomized controlled study support the use of ISE for enhancing pulmonary function and breath control for speech production in children with CP.

    1988-01-01

    A multi-input/output random vibration control algorithm was developed based on system identification concepts derived from random vibration spectral analysis theory. The unique features of the algorithm are: (1) the number of input excitors and the number of output control responses need not be identical; (2) the system inverse response matrix is obtained directly from the input/output spectral matrix; and (3) the system inverse response matrix is updated every control loop cycle to accommodate system amplitude nonlinearities. A laboratory demonstration case of two imputs with three outputs is presented to demonstrate the system capabilities.

    Active control of the spatial pump profile is proposed to exercise control over random laser emission. We demonstrate numerically the selection of any desired lasing mode from the emission spectrum. An iterative optimization method is employed, first in the regime of strong scattering where modes are spatially localized and can be easily selected using local pumping. Remarkably, this method works efficiently even in the weakly scattering regime, where strong spatial overlap of the modes precludes spatial selectivity. A complex optimized pump profile is found, which selects the desired lasing mode at the expense of others, thus demonstrating the potential of pump shaping for robust and controllable single mode operation of a random laser.

    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.

  17. Analyzing randomized controlled interventions: Three notes for applied linguists

    Full Text Available I discuss three common practices that obfuscate or invalidate the statistical analysis of randomized controlled interventions in applied linguistics. These are (a checking whether randomization produced groups that are balanced on a number of possibly relevant covariates, (b using repeated measures ANOVA to analyze pretest-posttest designs, and (c using traditional significance tests to analyze interventions in which whole groups were assigned to the conditions (cluster randomization. The first practice is labeled superfluous, and taking full advantage of important covariates regardless of balance is recommended. The second is needlessly complicated, and analysis of covariance is recommended as a more powerful alternative. The third produces dramatic inferential errors, which are largely, though not entirely, avoided when mixed-effects modeling is used. This discussion is geared towards applied linguists who need to design, analyze, or assess intervention studies or other randomized controlled trials. Statistical formalism is kept to a minimum throughout.

    Randomized controlled trials are the gold standard of evidence-based medicine. In the field of plastic surgery, designing these studies is much more challenging than in pharmaceutical medicine. Randomized trials in plastic surgery encompass several road blocks including problems shared with other surgical trials: equipoise, high cost, placebo issues and learning curves following the establishment of a novel approach. In addition, plastic surgery has more subjective outcomes, thus making study design even more difficult in assessing the end result.

    Full Text Available Background: Although evidences emphasize on the importance of aftercare programs to achieve continuity of care, different studies have revealed controversial results about the outcome. The objective of this study was to investigate the effect of aftercare program on outcome measures of patients with severe mental disorders. Materials and Methods: Of a total 123 eligible patients with severe mental disorders, 61 patients were randomly assigned to the intervention group and 62 patients to the control group. The interventions included follow-up phone calls, home visits, and psychoeducation for families. Assessments were performed on hospital admission, discharge and the following 3 rd , 6 th and 12 th month. Young Mania Rating Scale (YMRS, Hamilton Depression Rating Scale (HDRS, Positive and Negative Syndrome Scale (PANSS, Global Assessment of Functioning (GAF, Clinical Global Impression (CGI, and the World Health Organization Quality of Life Questionnaire (WHO-QOL were used. Data were analyzed through Chi square, t-test, Mann-Whitney-U, and Repeated Measures Analysis of Co-Variance. Results: Mean of the HDRS scores revealed significant difference between the two groups when HDRS scores on the admission day were controlled (P = 0.028. The level of functioning was significantly different between the two groups based on the sequential assessments of GAF (P = 0.040. One year after the onset of trial, the number of psychiatric readmissions were significantly different between the two groups (P = 0.036. Conclusion: Readmission rates could be reduced by aftercare services, through the first year, after discharge of patients with severe mental disorders. On the other hand, higher levels of functioning would be expected after one year.

    Pre-exam anxiety syndrome is a common condition occurring in pre-exam students and directly affects their examination performance and physical state. Wrist-ankle acupuncture has significant therapeutic effects in treating mental disorders and may also relieve the symptoms of pre-exam anxiety syndrome. To assess the therapeutic effect of wrist-ankle acupuncture on pre-exam anxiety syndrome. A total of 60 students who met the inclusion criteria of pre-exam anxiety syndrome were enrolled from a university in Shanghai and they were randomly divided into treatment group and control group. There were 30 cases in each group, and no case failed to follow-up. In the treatment group, wrist-ankle acupuncture was adopted to point upper 1 bilaterally (impression between flexor carpi ulnaris tendon and ulnar margin), and there was no requirement for Deqi (arrival of qi). In the control group, sham acupuncture was adopted. The treatment was applied 3 times totally in both groups one week before the exam, once every other day, each time with the needles retained for 30 min. The therapeutic effects were compared between two groups. Before and after 3 treatments, Sarason Test Anxiety Scale (TAS) and Expectation and Treatment Credibility Scale (ETCS) were measured and evaluated. The therapeutic effect experienced by the treatment group was better than that of the control group (P<0.05). There were no statistically significant differences in TAS and ETCS before treatment between the two groups. The scores of TAS after treatment in two groups were higher than those before treatment (P<0.05, P<0.01). There were statistical differences in TAS absolute difference and TAS relative difference between the two groups and the treatment group had better results (P<0.05, P<0.01). After treatment, patients in the treatment group had higher scores in ETCS than those in the control group (P<0.05, P<0.01). No adverse reaction was reported. Wrist-ankle acupuncture can relieve the symptoms of pre

    Full Text Available Background and Objectives: Most patients experience moderate to severe anxiety before cardiac catheterization. This study aimed to investigate the effect of Rosa aromatherapy on anxiety before cardiac catheterization. Methods: In this randomized controlled trial, 60 patients who met the inclusion criteria were conveniently sampled and randomly allocated to the experimental and control groups. Patients in the control group received routine care. In the experimental group, patients received routine care and Rosa aromatherapy for eighteen minutes. The level of anxiety was measured immediately before, and after the treatment. Results: In the stages before and after the study, there were no significant differences between the two groups in the terms of the mean scores of state and total anxiety. However, the mean score of trait anxiety in the experimental group was significantly lower than the control group. Furthermore, there was no significant difference between pre- and post-treatment in both groups. Conclusion: Most of the patients experience moderate to severe anxiety before cardiac catheterization. The findings of this study demonstrate that aromatherapy, as administered in this study, is not beneficial.

    To investigate the effect of mirror therapy on the gait of patients with subacute stroke. Randomized controlled experimental study. Outpatient rehabilitation hospital. Thirty-four patients with stroke were randomly assigned to two groups: a mirror therapy group (experimental) and a control group. The stroke patients in the experimental group underwent comprehensive rehabilitation therapy and mirror therapy for the lower limbs. The stroke patients in the control group underwent sham therapy and comprehensive rehabilitation therapy. Participants in both groups received therapy five days per week for four weeks. Temporospatial gait characteristics, such as single stance, stance phase, step length, stride, swing phase, velocity, and cadence, were assessed before and after the four weeks therapy period. A significant difference was observed in post-training gains for the single stance (10.32 SD 4.14 vs. 6.54 SD 3.23), step length (8.47 SD 4.12 vs. 4.83 SD 2.14), and stride length (17.03 SD 6.57 vs 10.54 SD 4.34) between the experimental group and the control group (p 0.05). We conclude that mirror therapy may be beneficial in improving the effects of stroke on gait ability. © The Author(s) 2014.

    OBJECTIVE To evaluate the effects of resistance exercise applied early after coronary artery bypass grafting. METHODS It is a randomized controlled trial with 34 patients undergoing coronary artery bypass grafting between August 2013 and May 2014. Patients were randomized into two groups by simple draw: a control group (n=17), who received conventional physical therapy and an intervention group (n=17), who received, additionally, resistance exercise. Pulmonary function and functional capacity were evaluated in preoperative period and hospital discharge by spirometry and the six-minute walk test. For statistical analysis, we used the following tests: Shapiro-Wilk, Mann-Whitney, Student's t and Fisher's exact. Variables with P<0.05 were considered significant. RESULTS Groups were homogeneous in terms of demographic, clinical and surgical variables. Resistance exercise exerted no effect on pulmonary function of intervention group compared to control group. However, intervention group maintained functional capacity at hospital discharge measured by percentage of predict distance in 6MWT (54.122.7% vs. 52.515.5%, P=0.42), while control group had a significant decrease (59.211.1% vs. 50.69.9%, P<0.016). CONCLUSION Our results indicate that resistance exercise, applied early, may promote maintenance of functional capacity on coronary artery bypass grafting patients, having no impact on pulmonary function when compared to conventional physical therapy.

    Background: The usefulness of the modified Atkins diet (mAD) in refractory epilepsy in adults has been rarely investigated. We aimed to evaluate the efficacy of mAD in adult with refractory epilepsy. Methods: In a controlled randomized clinical trial, we enrolled 66 refractory adult epileptic cases from February 2010 to December 2012. The patients were randomly divided into two groups, case groups (22 patients) used antiepileptic drugs and mAD and control group (32 patients) only use antiepileptic drugs. The primary outcome was at least 50% decrement in seizure frequency after 2 months of therapy. Results: No significant difference was shown in our data between groups regarding baseline characteristic. The differences of mean seizure attack after 2 months (P 50% seizure decrease at 1 and after 2 months and 12 (35.3%) had 50% decrease in seizure frequency. Furthermore, in mAD group, the mean urinary ketone positivity was 1.75 ± 0.28 and increasing liver enzyme was shown 5 cases (14.7%) in mAD group and 5 cases (15.6%) in control group (P < 0.050). Conclusion: The mAD may be effective as a cotherapy treatment for adults with refractory epilepsy and decrease 2.19 times seizure frequency in comparison with control groups. Trials with the more tolerant dietary regime, with larger sample size and longer duration, should be performed in future.

    Full Text Available Abstract Background Periodontitis is a common, chronic inflammatory disease caused by gram-negative bacteria leading to destruction of tissues supporting the teeth. Epidemiological studies have consistently shown increased frequency, extent and severity of periodontitis among diabetic adults. More recently, some controlled clinical trials have also suggested that periodontal treatment could improve glycaemic control in diabetic patients. However current evidence does not provide sufficient information on which to confidently base any clinical recommendations. The main objective of this clinical trial is to assess whether periodontal treatment could lead to a decrease in glycated haemoglobin levels in metabolically unbalanced diabetic patients suffering from chronic periodontitis. Methods The DIAPERIO trial is an open-label, 13-week follow-up, randomized, controlled trial. The total target sample size is planned at 150 participants, with a balanced (1:1 treatment allocation (immediate treatment vs delayed treatment. Periodontal treatment will include full mouth non-surgical scaling and root planing, systemic antibiotherapy, local antiseptics (chlorhexidine 0.12% and oral health instructions. The primary outcome will be the difference in change of HbA1c between the two groups after the 13-weeks' follow-up. Secondary outcomes will be the difference in change of fructosamine levels and quality of life between the two groups. Discussion The DIAPERIO trial will provide insight into the question of whether periodontal treatment could lead to an improvement in glycaemic control in metabolically unbalanced diabetic patients suffering from periodontitis. The results of this trial will help to provide evidence-based recommendations for clinicians and a draft framework for designing national health policies.

    Full Text Available Menopause is one of the most critical periods of woman's life. With reducing of ovarian estrogen; women are more prone to psychological and physical symptoms. The present study aimed to investigate the effect of melatonin on the climacteric symptoms.The present double blind, placebo randomized controlled clinical trial was conducted on 240 menopausal women (40 - 60 years old referring to the gynecology clinics of Shiraz University of Medical Sciences (January - November 2012. The participants were randomly divided into two groups through sortition. Demographic characteristics, Goldberg's general health questionnaire (GHQ, Greene Climacteric Scale and level of Follicle Stimulating Hormone (FSH were determined for both groups before the intervention. The intervention group received one 3mg melatonin tablet each night for 3 months and the control group received the placebo in the same period. Changes of climacteric symptoms and drug complications were measured 1, 2 and 3 months after the intervention.We analyzed the data of 99 postmenopausal women in the intervention group and 101 postmenopausal women in the control group. In the melatonin group, the climacteric symptoms score decreased from 35.73+11.6 to 17.09+10.22 during the 3-month study period and regardless of time, a significant difference was observed between the two groups (P<0.001. In addition, a significant difference was found between the two groups regarding various dimensions of the climacteric symptoms over time (P<0.001. No significant difference was found regarding side effects between the two groups (P= 0.135.The study findings showed that using melatonin improved the climacteric symptoms.

    Migrainous vertigo is a common cause of dizziness presenting to an otorhinolaryngology/otoneurology clinic. Although it causes a substantial burden to the individual and society there are no randomized controlled trails on prophylactic medication for this condition. Flunarizine, a calcium channel blocker has been used effectively in both migraine and vestibular conditions. This randomized control trial was undertaken in a tertiary academic referral center to evaluate the efficacy of flunarizine in patients with migrainous vertigo when compared to non-specific vestibular treatment of betahistine and vestibular exercises. The effect of flunarizine on two particularly disabling symptoms of vertigo and headache was studied. A total of 48 patients who were diagnosed with definitive migrainous vertigo completed the study of 12 weeks duration. Patients in arm A received 10-mg flunarizine daily along with betahistine 16 mg and paracetamol 1 gm during episodes, and arm B received only betahistine and paracetamol during episodes. Symptom scores were noted at the start of the study and at the end of 12 weeks. Analysis of the frequency of vertiginous episodes showed a significant difference between arm A and arm B (p = 0.010) and improvement in severity of vertigo between the two groups (p = 0.046). Headache frequency and severity did not improve to a significant degree in arm A as compared to arm B. The main side effects were weight gain and somnolence and this was not significantly different between the two groups. Flunarizine (10 mg) is effective in patients with migrainous vertigo who suffer from considerable vestibular symptoms.

    Wu-Ling-San (WLS) formula has been proved to prevent calcium oxalate nephrolithiasis both in vitro and in vivo. This is the first prospective, randomized and placebo-controlled clinical trial of WLS in calcium oxalate nephrolithiasis prevention. All patients who enrolled were asked to drink enough fluid to urinate at least 2 L daily during the study period. A 24-hour urine collection was performed to establish the baseline levels of multiple urinary parameters before taking the medicine. The patients were randomized and divided into two groups. The medication group took 2 gm WLS formula three times daily for 1 month. The control group took 2 gm placebo three times daily for 1 month. A 24-hour urine collection was performed to evaluate multiple urinary and serum parameters from all patients during the study period. A total of 39 patients were enrolled and 28 patients completed the study. Fourteen patients were allocated to WLS group and 14 patients to placebo group. After treatment, the mean urine output level increased to 2796.4 ± 525.7 ml/day (percentage of change, 13.9 %) in the WLS formula group. With placebo therapy, the mean decreased slightly to 2521.4 ± 762.7ml/day (percentage of change, -5.7 %). The percentage of change was significantly different between the two groups (independent t-test, P=0.02). No patient complained of side effects, such as fatigue, dizziness, musculoskeletal symptoms, or gastrointestinal disturbance. WLS formula is a promising adjunct to surgical and medical management of kidney stones. Active therapy with WLS formula has a positive effect on diuresis without leading to electrolyte imbalance.

    Yoga techniques practiced for varying durations have been shown to reduce state anxiety. This was never assessed in adolescents with polycystic ovarian syndrome (PCOS). To compare the effect of a holistic yoga program with the conventional exercise program on anxiety level in adolescents with PCOS. Ninety adolescent (15-18 years) girls from a residential college in Andhra Pradesh, who satisfied the Rotterdam criteria, were randomized into two groups. Anxiety levels were assessed at inclusion and after 12 weeks of intervention wherein yoga group practiced a holistic yoga module while the control group practiced a matching set of physical exercises (1 h/day, for 12 weeks). Mann-Whitney U test was used to compare difference scores (delta change) between the two groups Changes in state anxiety after the intervention were nonsignificantly different between the two groups (P=0.243), while changes after the intervention were significantly different between the two groups (P=0.002) for trait anxiety. Twelve weeks of a holistic yoga program in adolescents with PCOS is significantly better than physical exercise program in reducing anxiety symptoms.

    The myocardial protective effect of remote ischemic preconditioning has been demonstrated in heterogeneous groups of patients undergoing cardiac surgery. No studies have examined this technique in neonates. The present study was performed to examine the remote ischemic preconditioning efficacy in this high-risk patient group. A preliminary, randomized, controlled trial was conducted to investigate whether remote ischemic preconditioning in cyanosed neonates undergoing cardiac surgery confers protection against cardiopulmonary bypass. Two groups of neonates undergoing cardiac surgery were recruited for the present study: patients with transposition of the great arteries undergoing the arterial switch procedure and patients with hypoplastic left heart syndrome undergoing the Norwood procedure. The subjects were randomized to the remote ischemic preconditioning or sham control groups. Remote ischemic preconditioning was induced by four 5-minute cycles of lower limb ischemia and reperfusion using a blood pressure cuff. Troponin I and the biomarkers for renal and cerebral injury were measured pre- and postoperatively. A total of 39 neonates were recruited-20 with transposition of the great arteries and 19 with hypoplastic left heart syndrome. Of the 39 neonates, 20 were randomized to remote ischemic preconditioning and 19 to the sham control group. The baseline demographics appeared similar between the randomized groups. The cardiopulmonary bypass and crossclamp times were not significantly different between the 2 groups. The troponin I levels were not significantly different at 6 hours after cardiopulmonary bypass nor were the postoperative inotrope requirements. Markers of renal (neutrophil gelatinase-associated lipocalin) and cerebral injury (S100b, neuron-specific enolase) were not significantly different between the 2 groups. Our data suggest that remote ischemic preconditioning in hypoxic neonates undergoing cardiopulmonary bypass surgery does not provide

    Full Text Available We aimed to investigate the preventive effects of acupuncture for complications after radical hysterectomy. A single-center randomized controlled single-blinded trial was performed in a western-style hospital in China. One hundred and twenty patients after radical hysterectomy were randomly allocated to two groups and started acupuncture from sixth postoperative day for five consecutive days. Sanyinjiao (SP6, Shuidao (ST28, and Epangxian III (MS4 were selected with electrical stimulation and Zusanli (ST36 without electrical stimulation for thirty minutes in treatment group. Binao (LI14 was selected as sham acupuncture point without any stimulation in control group. The main outcome measures were bladder function and prevalence of postoperative complications. Compared with control group, treatment group reported significantly improved bladder function in terms of maximal cystometric capacity, first voiding desire, maximal flow rate, residual urine, and bladder compliance, and decreased bladder sensory loss, incontinence, and urinary retention on fifteenth and thirtieth postoperative days. Treatment group showed significant advantage in reduction of urinary tract infection on thirtieth postoperative day. But no significant difference between groups was observed for lymphocyst formation. By improving postoperative bladder function, early intervention of acupuncture may provide a valuable alternative method to prevent bladder dysfunctional disorders and urinary tract infection after radical hysterectomy.

    To assess the effects of mechanical dilatation of the cervix during cesarean section on postoperative morbidity. A total of 447 women with elective cesarean section were included in the Dondi trial (Dilatation or no dilatation of the cervix during cesarean section). The primary outcome measure of this randomized controlled trial was postpartum hemorrhage (PPH) within 6 weeks. Infectious morbidity (puerperal fever, endometritis, wound infection, and urinary tract infection), blood loss (need for blood transfusion or change in hemoglobin levels), and operating time were also evaluated. The rate of PPH within 6 weeks was not different between the two groups [dilatation group: 5 (2.4 %), no dilatation group: 3 (1.2 %), p = 0.479]. Infectious morbidity, blood loss, and operating time were not diverse as well. The only significant difference between the two groups was the rate of retained products of conception with fewer cases after cervical dilatation (0 versus 6.2 %, p cesarean section compared with no dilatation of the cervix did not influence the risk of postpartum hemorrhage. However, there were fewer cases with retained products of conception after dilatation.

    Full Text Available Abstract Background World-wide healthcare systems are faced with an epidemic of type 2 diabetes. In the United Kingdom, clinical care is primarily provided by general practitioners (GPs rather than hospital specialists. Intermediate care clinics for diabetes (ICCD potentially provide a model for supporting GPs in their care of people with poorly controlled type 2 diabetes and in their management of cardiovascular risk factors. This study aims to (1 compare patients with type 2 diabetes registered with practices that have access to an ICCD service with those that have access only to usual hospital care; (2 assess the cost-effectiveness of the intervention; and (3 explore the views and experiences of patients, health professionals and other stakeholders. Methods/Design This two-arm cluster randomized controlled trial (with integral economic evaluation and qualitative study is set in general practices in three UK Primary Care Trusts. Practices are randomized to one of two groups with patients referred to either an ICCD (intervention or to hospital care (control. Intervention group: GP practices in the intervention arm have the opportunity to refer patients to an ICCD - a multidisciplinary team led by a specialist nurse and a diabetologist. Patients are reviewed and managed in the ICCD for a short period with a goal of improving diabetes and cardiovascular risk factor control and are then referred back to practice. or Control group: Standard GP care, with referral to secondary care as required, but no access to ICCD. Participants are adults aged 18 years or older who have type 2 diabetes that is difficult for their GPs to control. The primary outcome is the proportion of participants reaching three risk factor targets: HbA1c (≤7.0%; blood pressure ( Discussion Forty-nine practices have been randomized, 1,997 patients have been recruited to the trial, and 20 patients have been recruited to the qualitative study.

    Dysmenorrhea is common among women of reproductive age. This study aim was to investigate the effect of vitamin D (vit D) supplementation in treatment of primary dysmenorrhea with vit D deficiency. A randomized double-blind placebo-controlled clinical trial was conducted on 60 women with primary dysmenorrhea and vit D deficiency referred to our clinic at Arash Women's Hospital from September 2013 to December 2014. Eligible women were randomly assigned into treatment and control groups (30 in each group). Individuals in the treatment group received 50 000 IU oral vit D and the control group received placebo weekly for eight weeks. After two months of treatment, there was a significant difference in serum vit D concentration between the two groups (p D supplementation for eight weeks in patients with primary dysmenorrhea and vit D deficiency could improve pain intensity.

    The purpose of this randomized control trial was to determine the performance of a novel rule-based adaptive closed-loop system for propofol administration using the bispectral index (BIS(R)) and to compare the system's performance with manual administration. The effectiveness of the closed-loop system to maintain BIS close to a target of 45 was determined and compared with manual administration. After Institutional Review Board approval and written consent, 40 patients undergoing major surgery in a tertiary university hospital were allocated to two groups using computer-generated block randomization. In the Closed-loop group (n = 20), closed-loop control was used to maintain anesthesia at a target BIS of 45, and in the Control group (n = 20), propofol was administered manually to maintain the same BIS target. To evaluate each technique's performance in maintaining a steady level of hypnosis, the BIS values obtained during the surgical procedure were stratified into four clinical performance categories relative to the target BIS: 30% defined as excellent, good, poor, or inadequate control of hypnosis, respectively. The controller performance was compared using Varvel's controller performance indices. Data were compared using Fisher's exact test and the Mann-Whitney U test, P performance error and the median absolute performance error were significantly lower in the Closed-loop group compared with the Control group (-1.1 +/- 5.3% vs -10.7 +/- 13.1%; P = 0.004 and 9.1 +/- 1.9% vs 15.7 +/- 7.4%; P performance than manual administration of propofol.

    To study the effectiveness of the addition of citicoline to patching in the treatment of amblyopia in the age group of 4-13 years. A randomized controlled trial, which included patients who were randomly divided into two groups. Both the groups received patching therapy till plateau was achieved in phase 1 of the study. Then in phase 2, group I received citicoline plus patching and group II continued to receive only patching. Outcome was measured by the visual acuity in logMAR every month in phase 1 till plateau was achieved and then for 12 months in phase 2. No significant difference was found in the mean visual acuities in these two groups in phase 1 till plateau was reached. In phase 2, for the initial four months, there was no significant difference in the visual acuities in these two groups, at the respective intervals. However, five months onward, up to 12 months, there was a significant difference in the visual acuities in these groups.The result was the same in younger patients ( seven years of age). In phase 2, the mean proportional improvement in group I was significantly more than that in group II, at two months and onward, at the respective intervals. The improvement in visual acuity with citicoline plus patching was significantly more than that with patching alone, in one year of treatment.

    Regardless of the high success rate, patients commonly report the occurrence of tooth sensitivity during the in-office bleaching procedures. Recently, it has been demonstrated that using a customized tray (called sealed in-office bleaching technique) reduces peroxide penetration. The aim of this randomized clinical study was to evaluate tooth sensitivity and bleaching efficacy of sealed bleaching, in comparison with a conventional in-office technique. Twenty patients were randomized allocated in two groups in which 35% hydrogen peroxide gel was used in a single 45-min application. For the sealed technique, a customized bleaching tray was fabricated and carefully positioned over the bleaching agent during the session. The color was recorded at a baseline, 7 and 28 days after the bleaching session, using Vita Easy Shade spectrophotometer. Tooth sensitivity was recorded during (20 and 40 min) and immediately after the treatment using a visual analogue scale. The bleaching efficacy was evaluated by repeated-measures ANOVA, while the absolute risk of tooth sensitivity and its intensity were evaluated by Fisher's exact and Mann-Whitney tests, respectively (α=0.05). No significant difference on bleaching efficacy was observed between the conventional (7.4 and 8.1 ΔE) and sealed techniques (7.8 and 8.3 ΔE) at both evaluation periods. No significant difference was observed regarding the absolute risk of tooth sensitivity (p=0.15). Sealed technique showed a significant decrease of sensitivity intensity after 40 min (p=0.03). Sealed bleaching technique was able to reduce the sensitivity intensity during the bleaching procedure, without jeopardizing the bleaching efficacy.

    First of all we introduce the concepts of infinitely dimensional control Markov branching chains in random environments (β-MBCRE) and prove the existence of such chains, then we introduce the concepts of conditional generating functionals and random Markov transition functions of such chains and investigate their branching property. Base on these concepts we calculate the moments of the β-MBCRE and obtain the main results of this paper such as extinction probabilities, polarization and proliferation rate. Finally we discuss the classification ofβ-MBCRE according to the different standards.

    Two studies have demonstrated an analgesic effect of maternal milk odor in preterm neonates, without specifying the method of olfactory stimulation. Research aim: This study aimed to assess the analgesic effect of maternal milk odor in preterm neonates by using a standardized method of olfactory stimulation. This trial was prospective, randomized, controlled, double blinded, and centrally administered. The inclusion criteria for breastfed infants included being born between 30 and 36 weeks + 6 days gestational age and being less than 10 days postnatal age. There were two groups: (a) A maternal milk odor group underwent a venipuncture with a diffuser emitting their own mother's milk odor and (2) a control group underwent a venipuncture with an odorless diffuser. The primary outcome was the Premature Infant Pain Profile (PIPP) score, with secondary outcomes being the French scale of neonatal pain-Douleur Aiguë du Nouveau-né (DAN) scale-and crying duration. All neonates were given a dummy. Our study included 16 neonates in the maternal milk odor group and 17 in the control group. Neonates exposed to their own mother's milk odor had a significantly lower median PIPP score during venipuncture compared with the control group (6.3 [interquartile range (IQR) = 5-10] versus 12.0 [IQR = 7-13], p = .03). There was no significant difference between the DAN scores in the two groups ( p = .06). Maternal milk odor significantly reduced crying duration after venipuncture (0 [IQR = 0-0] versus 0 [IQR = 0-18], p = .04). Maternal milk odor has an analgesic effect on preterm neonates.

    Full Text Available Background: Oral aphthous is one of the most common oral mucosal inflammatory disorders which are very painful. There is no definite medical strategy up to now for aphthous treatment. Recently, some researchers have focused on immunomodulatory drugs such as tacrolimus and pimecrolimus in preventing aphthus recurrences. The aim of this study is to assess the effect of pimecrolimus cream against placebo in management of oral minor aphthous.Methods: The study is a randomized clinical trial, was done in “Shariati” hospital and Isfahan Skin Research Center. 62 patients with minor aphthuos were included and divided randomly to two groups (31 in each. In experimental group, pimecrolimus cream was applied for two weeks and cold cream for the same duration in control group. Patients were followed for 3 and one week; results were assessed in recovery after drug administration. Compared variables between two groups were including: the size of lesions, the time to recovery and pain intensity.Results: Results showed that mean size lesion in experimental and placebo group after complete recovery reduced (23.6 ±15.3 and 24.8 ±15 mm respectively but it was not significant (P: 0.1. Mean time for recovery in both groups was 8±2.2 and 9.5±2.5 respectively which was significant in pimecrolimus treated patients (P: 0.014. Also mean degree for pain intensity measured by pain scale method was reduced significantly in test group (6 ± 1.2 before treatment and 5.3 ± 1.1 after treatment, P<0.001.Conclusion: This study stated that pimecrolimus cream has an appropriate effect in reduction of recovery time and pain in minor aphthous compared to placebo but more clinical studies are needed to better conclusion.

    A new design of vacuum extractor cup--'the New Generation cup'--has recently been introduced into clinical practice. Its major modification is a traction cord which passes around the rim of the cup for 180 degrees and is free to slide within the rim. Claims that this design 'enables the operator to pull obliquely without causing the cup to tilt' and thereby 'reduces failure rates, reduces the incidence of scalp trauma and increases operator confidence' have been evaluated in a randomized controlled trial. 123 women with singleton pregnancies of 37 completed weeks or more, with a cephalic presentation and for whom a decision to deliver by vacuum extraction had been taken, were randomly allocated to the 'New Generation' cup or BIRD's original vacuum extractor cup; 50 mm anterior and posterior cups were used in both groups as appropriate. The two groups were comparable at entry and delivered by obstetricians of similar status. The two types of cup were similar in respect of number of failures to deliver with the vacuum extractor, correct positioning of the cup, number of pulls required for delivery and time taken to expedite delivery. Cup detachments occurred in nine cases allocated to the 'New Generation' cup compared with four allocated to the original BIRD cup. The babies in the two groups were in similar condition at birth and sustained similar amounts of scalp trauma. Neonatal jaundice, both clinical and biochemical, was more common in babies delivered with the 'New Generation cup' and this was reflected in greater use of phototherapy in this group. Operators were equally divided in their preference of cup.(ABSTRACT TRUNCATED AT 250 WORDS)

    The study aimed at comparing the effectiveness and maternal satisfaction of oral misoprostol with vaginal misoprostol for induction of labor at term. A randomized controlled trial of 140 term pregnant women at the University of Nigeria Teaching Hospital Enugu, Nigeria, was conducted from April 2011 to May 2012. The women were equally randomized into two groups (A and B) to receive oral and vaginal misoprostol, respectively. The vaginal route reduced the mean induction-vaginal delivery interval by four-and-half hours (20.7 ± 12.1 vs. 16.2 ± 10.4; mean difference: 4.50, 95% CI 0.63-0.82; p = 0.02). Furthermore, the mean dose of misoprostol required to achieve induction of labor and the mean duration of oxytocin augmentation when indicated were significantly less in the vaginal group than in the oral group (2.5 ± 1.3 vs. 2.0 ± 1.1; mean difference: 0.50, 95% CI 0.10-0.90; p = 0.02 and 4.6 ± 3.2 vs. 3.4 ± 3.1; mean difference: 1.20, 95% CI 0.15-0.23; p = 0.03 respectively). However, neonatal complications and maternal satisfaction were similar between the two groups. Both routes of administration are effective in the induction of labor at term and have comparable maternal satisfaction. However, the vaginal route has the added advantage of shorter induction-delivery interval among others, and thus should be highly considered when induction of labor is indicated at term.

    Most parameters regarding hamstring flexibility training programs have been investigated; however, the joint (i.e. hip or knee) on which the stretching should preferentially be focused needs to be further explored. This randomized controlled assessor-blinded study aimed to investigate the influence of this parameter. We randomly assigned 111 asymptomatic participants with tight hamstring muscles in three groups: a control group and two groups following a different home-based 8-week (five 10-minute sessions per week) hamstring stretching program (i.e. stretching performed by flexing the hip while keeping the knee extended [SH] or by first flexing the hip with a flexed knee and then extending the knee [SK]). Range of motion (ROM) of hip flexion and knee extension were measured before and after the stretching program by means of the straight leg raising test and the passive knee extension angle test, respectively. Eighty-nine participants completed the study. A significant increase in ROM was observed at post-test. Analyses showed significant group-by-time interactions for changes regarding all outcomes. Whereas the increase in hip flexion and knee extension ROM was higher in the stretching groups than in the CG (especially for the SH group p stretching groups were observed (p > 0.05). In conclusion, the fact that both stretching programs resulted in similar results suggests no influence of the joint at which the stretching is focused upon, as assessed by the straight leg raising and knee extension angle tests.

    Full Text Available Background: Despite the fact that effect of massage with or without oil on the baby′s weight gain is not clear, but recent studies have shown that massage with essential oils make lipid absorption through the skin. The aim of this study was to evaluate the effect of olive oil massage on weight gain in preterm infants. Materials and Methods: This study was a single-blind, randomized controlled clinical trial. In this study, infants who met inclusion criteria for the study were divided into two groups by using random numbers table. Newborns in intervention group were under massage for 10 days and 3 times for 15 min daily; the mother of these newborns had been trained already using olive oil. Moreover, the infants of the control group were under massaging without oil same as the above-mentioned method. Researchers weighed babies daily during 10 days and recorded it at the checklist. Data from the study were reviewed and analyzed by descriptive statistics and repeated measure test using the statistical software SPSS/13. Results: This study showed that the neonatal weight gain in the infants with the oil massage was 21 g daily in average, whereas the increase in infant massage without oil was 7 g. This difference was statistically significant (P < 0.001. Conclusion: Considering the positive effect of infant massage on weight gain in premature infants with olive oil, it is recommended that nurses use oil in infant massage in the neonatal units.

    This study aims to determine the impact of increasing polyunsaturated fatty acid intake on blood glucose, lipid metabolism, and pregnancy outcomes of pregnant women with gestational diabetes mellitus. Under constant total energy and protein intake, 84 pregnant women with gestational diabetes mellitus were randomly divided into the experimental and control groups, which were given oil-rich and conventional low-oil meals, respectively. After the dietary intervention, the intake and energy supply of fat and the three fatty acids were significantly higher in the experimental group than the control group (pchange in the control group. In both the intervention and the control group, fasting blood glucose, 2 h postprandial plasma glucose, and the insulin resistance index decreased significantly post-intervention (pchanges were consistent between groups. Pregnancy outcomes did not differ significantly between the two groups (p>0.05). An appropriate increase in polyunsaturated fatty acid intake benefits pregnant women with gestational diabetes mellitus as well as fetuses, as long as the diet therapy follows basic recommendations and total energy intake is strictly controlled.

    Full Text Available Background: In developing countries it is important to the exploration of available and safe regimens for medical abortion. The present study was designed to assess the effect of letrozole compared to placebo pretreatment followed by sublingual misoprostol for therapeutic abortion in eligible women with gestational age less than 17 weeks. Materials and Methods: In this randomized control trail, 130 women eligible for legal abortions were randomly divided into two groups of case and controls. Cases received daily oral dose of 10 mg letrozole 10 mg letrozole for three days followed by sublingual misoprostol. Controls received daily oral dose of placebo followed by sublingual misoprostol. The dose of misoprostol was administrated according to ACOG guidelines based on patients′ gestational age. The rate of complete abortion, induction-of-abortion time, and side-effects were assessed as main outcomes. Results: Complete abortion was observed in 46 (76.7% letrozole group and 26 (42.6% controls (P < 0.0001. Also, in 14 subjects of letrozole group and 35 subjects in placebo group, the placenta was not delivered during follow-up and curettage was performed. The mean interval induction-to-abortion was 5.1 h in letrozole group and 8.9 h in control (P < 0.0001. The cumulative rates of the induction-of-abortion time were a significant difference between the two groups (P < 0.0001. The incidence and severity of side-effects was comparable for the two groups (P = 0.9. Conclusion: Letrozole could be a quite beneficial adjuvant to misoprostol for induction of complete abortion in those who are candidates for legal medical abortion.

    Objective To study the interruptive effect of hepatitis B virus (HBV) specific immunolobulin (HBIG) before delivery in attempt to prevent intrauterine transmission of HBV.Methods Nine hundred and eighty HBsAg carrier pregnant women were randomly divided into HBIG group and control group. Each subject in the HBIG group received 200 IU or 400 IU of HBIG intramuscularly at 3, 2 and 1 month before delivery. The subjects in the control group did not receive any specific treatment. All newborn infants received 100 IU of HBIG intramascularty after venous blood samples were taken at birth and 2 weeks after birth, followed by 30 μg plasma-derived HB vaccine or 5 μg recombinant yeast-derived hepatitis B vaccine at 1, 2 and 7 months of age. Blood tests were performed for all the lying-in women and their neonates. Blood specimens were tested for HBsAg and HBeAg by enzyme immunoassay. All infants were followed up for 1 year.Results In the HBIG group, 491 neonates were born to 487 HBV carrier mothers; and in the control group, 496 neonates were born to 493 HBV carrier mothers. The rates of intrauterine transmission in the two groups were 14.3% and 5.7% respectively (χ2=20.280, P<0.001), and the rates of chronic hepatitis B in the two groups were 2.2% and 7.3% respectively (χ2=13.696, P<0.001). The high risk factors of intrauterine HBV infection included HBsAg HBeAg double positive and HBV DNA positive in the peripheral blood of pregnant women.Conclusion HBV infection in the uterus may be interrupted by injecting multiple intramuscular HBIG injections before delivery without causing any side-effects.

    Full Text Available Introduction: Dental plaque is a well-known etiologic factor for gingivitis. Ayurvedic drugs have been used since ancient times to treat diseases including periodontal diseases. Toothpastes made from herbal medicines are used in periodontal therapy to control bleeding and reduce inflammation. Aim: To compare the effectiveness of herbal and nonherbal fluoridated toothpaste on plaque and gingivitis among residents of ladies hostel in Mathura City. Materials and Methods: A randomized controlled clinical trial was carried out on 60 participants aged 18-30 years residing in a ladies hostel of Mathura City. The 60 participants were randomly allocated into two groups: Group-I: Experimental group using herbal toothpaste, Group-II: Control group using fluoridated toothpaste. The subjects were asked to brush twice daily with the assigned dentifrice using standardized brushing technique for 46 days. The plaque and gingival indices were recorded according to Silness and Loe (1964 and Loe and Silness (1963, respectively. These parameters were assessed at baseline, 3 weeks, and 6 weeks. Data were analyzed by Student paired t-test and unpaired t-test using Statistical Package for the Social Sciences version 21 manufactured by IBM Corporation - Armonk, New York, US. Results: Baseline plaque and gingival scores were found 1.02 ± 0.02 and 0.88 ± 0.06 for the experimental group and 1.02 ± 0.03 and 0.81 ± 0.08 for control group, respectively. After 6 weeks plaque and gingival scores were found 0.77 ± 0.07 and 0.72 ± 0.08 for experimental group and 0.78 ± 0.07 and 0.73 ± 0.11 for control group, respectively. Statistically significant differences were obtained before and after intervention in both groups (P ≤ 0.05. Conclusion: The herbal toothpaste was as effective as the conventionally formulated fluoride dentifrice in controlling plaque and gingivitis.

    Full Text Available Abstract Background Recent research indicates that 35 percent of blue-collar workers in the US currently smoke while only 20 percent of white-collar workers smoke. Over the last year, we have been working with heavy equipment operators, specifically the Local 324 Training Center of the International Union of Operating Engineers, to study the epidemiology of smoking, which is 29% compared to 21% among the general population. For the current study funded by the National Cancer Institute (1R21CA152247-01A1, we have developed the Tobacco Tactics website which will be compared to the state supported 1-800-QUIT-NOW telephone line. Outcome evaluation will compare those randomized to the Tobacco Tactics web-based intervention to those randomized to the 1-800-QUIT-NOW control condition on: a 30-day and 6-month quit rates; b cotinine levels; c cigarettes smoked/day; d number of quit attempts; and e nicotine addiction. Process evaluation will compare the two groups on the: a contacts with intervention; b medications used; c helpfulness of the nurse/coach; and d willingness to recommend the intervention to others. Methods/Design This will be a randomized controlled trial (N = 184. Both interventions will be offered during regularly scheduled safety training at Local 324 Training Center of the International Union of Operating Engineers and both will include optional provision of over-the-counter nicotine replacement therapy and the same number of telephone contacts. However, the Tobacco Tactics website has graphics tailored to Operating Engineers, tailored cessation feedback from the website, and follow up nurse counseling offered by multimedia options including phone and/or email, and/or e-community. Primary Analysis of Aim 1 will be conducted by using logistic regression to compare smoking habits (e.g., quit rates of those in the intervention arm to those in the control arm. Primary analyses for Aim 2 will compare process measures (e.g., medications

    Diep, H. T.; Kaufman, Miron; Kaufman, Sanda

    2017-03-01

    We propose a "social physics" model for two-group conflict. We consider two disputing groups. Each individual i in each of the two groups has a preference si regarding the way in which the conflict should be resolved. The individual preferences span a range between + M (prone to protracted conflict) and - M (prone to settle the conflict). The noise in this system is quantified by a "social temperature". Individuals interact within their group and with individuals of the other group. A pair of individuals (i , j) within a group contributes -si ∗sj to the energy. The inter-group energy of individual i is taken to be proportional to the product between si and the mean value of the preferences from the other group's members. We consider an equivalent-neighbor Renyi-Erdos network where everyone interacts with everyone. We present some examples of conflicts that may be described with this model.

    Full Text Available BACKGROUND: Previous studies suggest that electroacupuncture possesses therapeutic benefits for depressive disorders. The purpose of this study was to determine whether dense cranial electroacupuncture stimulation (DCEAS could enhance the antidepressant efficacy in the early phase of selective serotonin reuptake inhibitor (SSRI treatment of major depressive disorder (MDD. METHODS: In this single-blind, randomized, controlled study, patients with MDD were randomly assigned to 9-session DCEAS or noninvasive electroacupuncture (n-EA control procedure in combination with fluoxetine (FLX for 3 weeks. Clinical outcomes were measured using the 17-item Hamilton Depression Rating Scale (HAMD-17, Clinical Global Impression-severity (CGI-S, and Self-rating Depression Scale (SDS as well as the response and remission rates. RESULTS: Seventy-three patients were randomly assigned to n-EA (n = 35 and DCEAS (n = 38, of whom 34 in n-EA and 36 in DCEAS group were analyzed. DCEAS-treated patients displayed a significantly greater reduction from baseline in HAMD-17 scores at Day 3 through Day 21 and in SDS scores at Day 3 and Day 21 compared to patients receiving n-EA. DCEAS intervention also produced a higher rate of clinically significant response compared to n-EA procedure (19.4% (7/36 vs. 8.8% (3/34. The incidence of adverse events was similar in the two groups. CONCLUSIONS: DCEAS is a safe and effective intervention that augments the antidepressant efficacy. It can be considered as an additional therapy in the early phase of SSRI treatment of depressed patients. TRIAL REGISTRATION: Controlled-Trials.com ISRCTN88008690.

    The purpose of this randomized controlled trial was to investigate the influences of music during kangaroo care (KC) on maternal anxiety and preterm infants' responses. There are no experimental studies that explore the influences of combination of music and KC on psychophysiological responses in mother-infant dyads. Purposive sampling was used to recruit 30 hospitalized preterm infants body weight 1500 gm and over, gestational age 37 weeks and lower from two NICUs. Mother-infant dyads were randomly assigned to the treatment and the control group using permuted block randomization stratified on gender. There were 15 mother-infant dyads in each group. Subjects in the treatment dyads listened to their choice of a lullaby music during KC for 60 min/section/day for three consecutive days. Control dyads received routine incubator care. Using a repeated measures design with a pretest and three posttests, the responses of treatment dyads including maternal anxiety and infants' physiologic responses (heart rate, respiratory rate, and O2 saturation) as well as behavioural state were measured. The results revealed that there were no significant differences between the two groups on infants' physiologic responses and the values were all in the normal range. However, infants in the treatment group had more occurrence of quiet sleep states and less crying (pMusic during KC also resulted in significantly lower maternal anxiety in the treatment group (peffect. The findings provide evidence for the use of music during KC as an empirically-based intervention for bahavioural state stability and maternal anxiety in mother-infant dyads.

    To compare, in an unselected population of nulliparous pregnant women, the postnatal effect of prenatal supervised pelvic floor muscle training with written instructions on postpartum urinary incontinence (UI). In a randomized controlled trial in two parallel groups, 282 women were recruited from five university teaching hospitals in France and randomized during the second trimester of pregnancy. The physiotherapy group received prenatal individually supervised exercises. Both groups received written instructions about how to perform exercises at home. Women were blindly assessed at baseline, end of pregnancy, and 2 and 12 months postpartum. The primary outcome measured was UI severity, assessed with an International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form score (range 0-21; 1-5 is slight UI) at 12 months postpartum; other outcomes were UI prevalence and pelvic floor troubles assessed using self-administered questionnaires. To give a 1-point difference in UI severity score, we needed 91 women in each group (standard deviation 2.4, α=0.05, β=0.20, and bilateral analysis). Between February 2008 and June 2010, 140 women were randomized in the physiotherapy group and 142 in the control group. No difference was observed between the two groups in UI severity, prevalence, or pelvic floor troubles at baseline, end of pregnancy, and at 2 and 12 months postpartum. At 12 months postpartum, the primary outcome was available for 190 women (67.4%); mean UI severity was 1.9 in the physiotherapy group compared with 2.1 in the control group (P=.38). Prenatal supervised pelvic floor training was not superior to written instructions in reducing postnatal UI. ClinicalTrials.gov; www.clinicaltrials.gov, NCT00551551. I.

    2013-01-01

    We demonstrate an experimental technique that allows to achieve a robust control on the emission spectrum of a micro random laser and to select individual modes with sub-nanometer resolution. The presented approach relies on an optimization protocol of the spatial profile of the pump beam. Here we demonstrate not only the possibility to increase the emission at a wavelength, but also that we can isolate an individual peak suppressing unwanted contributions form other modes.

    Despite adequate treatment with antipsychotics, a substantial number of patients with schizophrenia demonstrate only suboptimal clinical outcome. To overcome this challenge, various psychopharmacological combination strategies have been used, including antidepressants added to antipsychotics. To analyze the efficacy of add-on antidepressants for the treatment of negative, positive, cognitive, depressive, and antipsychotic-induced extrapyramidal symptoms in schizophrenia, published randomized controlled trials assessing the efficacy of adjunctive antidepressants in schizophrenia were reviewed using the following parameters: baseline clinical characteristics and number of patients, their on-going antipsychotic treatment, dosage of the add-on antidepressants, duration of the trial, efficacy measures, and outcomes. There were 36 randomized controlled trials reported in 41 journal publications (n=1582). The antidepressants used were the selective serotonin reuptake inhibitors, duloxetine, imipramine, mianserin, mirtazapine, nefazodone, reboxetin, trazodone, and bupropion. Mirtazapine and mianserin showed somewhat consistent efficacy for negative symptoms and both seemed to enhance neurocognition. Trazodone and nefazodone appeared to improve the antipsychotics-induced extrapyramidal symptoms. Imipramine and duloxetine tended to improve depressive symptoms. No clear evidence supporting selective serotonin reuptake inhibitors' efficacy on any clinical domain of schizophrenia was found. Add-on antidepressants did not worsen psychosis. Despite a substantial number of randomized controlled trials, the overall efficacy of add-on antidepressants in schizophrenia remains uncertain mainly due to methodological issues. Some differences in efficacy on several schizophrenia domains seem, however, to exist and to vary by the antidepressant subgroups--plausibly due to differences in the mechanisms of action. Antidepressants may not worsen the course of psychosis. Better designed

    2012-01-01

    We show that the degree of localization for the modes of a random laser (RL) is affected by the inter mode interaction that is controlled by shaping the spot of the pump laser. By experimentally investigating the spatial properties of the lasing emission we infer that strongly localized modes are activated in the low interacting regime while in the strongly interacting one extended modes are found lasing. Thus we demonstrate that the degree o localization may be finely tuned at the micrometer level.

    A total of 100 osteoarthritis patients undergoing unilateral total knee arthroplasty were randomly assigned to receive either a multimodal analgesia protocol, comprising oral celecoxib and tramadol before and after surgery and intra-articular injection of large doses of morphine, ropivacaine, adrenaline and betamethasone during surgery (trial group), or oral and intra-articular placebo (control group). All patients received patient-controlled analgesia for 48 h after surgery. Morphine consumption up to 48 h after surgery was significantly lower in the trial than in the control group. Compared with the control group, the trial group had significantly lower visual analogue scale (VAS) scores for pain at rest from 6 h to 7 days after surgery and significantly lower VAS scores during activity from 24 h to 7 days after surgery. Active straight leg raise and active 90 degrees knee flexion were achieved sooner and range of knee movement at postoperative days 1 - 15 were significantly greater in the trial group. Postoperative wound healing, infection, blood pressure, heart rate, rash, respiratory depression, urinary retention and deep vein thrombosis were similar in the two groups, but nausea and vomiting were significantly less frequent in the trial group.

    To investigate the safety and efficacy of yangxinkang tablets in patients with chronic heart failure (CHF) and syndrome of qi and yin deficiency, blood stasis, and water retention. In a double-blinded, randomized, placebo-controlled, multicenter clinical trail, 228 patients with CHF New York Heart Association (NYHA) class II or III in stage C were assigned by randomized block method to two groups in a 1:1 ratio to undergo either conventional Western treatment or conventional treatment plus yangxinkang tablets for 4 weeks. The outcome measure were effect of cardiac function, Chinese medicine (CM) syndromes, scores of symptoms, signs, and quality of life measured by Minnesota Living with heart failure questionnaire (MLHFQ) before and after the treatment. Totally 112 patients were analyzed in the treatment group and 109 in the control group. They were comparable in NYHA functional class, basic parameters and primary diseases before treatment. Cardiac function and CM syndromes were greatly ameliorated in both groups after treatment. Total effective rates of cardiac function and CM syndrome in the treatment group were significantly higher than those in the control group (Pgasp, cough with phlegm, pulmonary rales and jugular vein engorgement between the two groups (P0.05). There was no obvious adverse reaction in either group noted during the study. Yangxinkang tablets were safe and efficacious in improving cardiac function, CM syndromes, symptoms, signs, and quality of life in patients with CHF class II or III in stage C on the base of conventional treatment.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    This paper studies a stochastic linear quadratic optimal control problem (LQ problem, for short), for which the coefficients are allowed to be random and the cost functional is allowed to have a negative weight on the square of the control variable. The authors introduce the stochastic Riccati equation for the LQ problem. This is a backward SDE with a complicated nonlinearity and a singularity. The local solvability of such a backward SDE is established, which by no means is obvious. For the case of deterministic coefficients, some further discussions on the Riccati equations have been carried out. Finally, an illustrative example is presented.

    2017-01-01

    Full Text Available The paper deals with a mathematical model that simulates the random occurrence of events during cutting processes by milling. The evolution of certain parameters that typify the cutting processes depends on predictable and non-predictable variables. In this context, either the material hardness that varies in different sides of billet, or cutting depth, can act as non-predictable variables. In order to design a response in terms of cutting parameters to non-predictable variations of inputs, a simulation of such phenomena is very useful. A mathematical model that generates random events, both in terms of non-uniform frequency and intensity is here described. A virtual instrument built in LabVIEW generates (pseudo random events based on a combination of random numbers, as the evolution of the simulated process to be much like a real one. Furthermore the user of virtual instrument can generate himself events at certain moments and of certain intensity. This can be a useful tool to study the algorithms of designing the response which should re-balance the process within adaptive control systems.

    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.

    Full Text Available We aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain. A single-center randomized controlled single-blind trial was performed in a general medical practice in Germany run by a Chinese-born medical doctor trained in western and Chinese medicine. One hundred and fifty outpatients with chronic low back pain were randomly allocated to two groups (78 standardized and 72 individualized acupuncture. Patients received either standardized acupuncture or individualized acupuncture. Treatment encompassed between 10 and 15 treatments based on individual symptoms with two treatments per week. The main outcome measure was the area under the curve (AUC summarizing eight weeks of daily rated pain severity measured with a visual analogue scale (0 mm = no pain, 100 mm = worst imaginable pain. No significant differences between groups were observed for the AUC (individualized acupuncture mean: 1768.7 (95% CI, 1460.4; 2077.1; standardized acupuncture 1482.9 (1177.2; 1788.7; group difference, 285.8 (−33.9; 605.5 P=0.080. In this single-center trial, individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain. As a next step, a multicenter noninferiority study should be performed to investigate whether standardised acupuncture treatment for chronic low back pain might be applicable in a broader usual care setting. This trial is registered with ClinicalTrials.gov NCT00758017.

In this randomized trial we examined the effectiveness of such a stepped care model. Methods The study population consisted of primary care attendees aged 18-65 years with minor or major DSM-IV depressive and/or anxiety disorders, recruited through screening. We randomized 120 patients to either stepped care or care as usual. The stepped care program consisted of (1 watchful waiting, (2 guided self-help, (3 short face-to-face Problem Solving Treatment and (4 pharmacotherapy and/or specialized mental health care. Patients were assessed at baseline and after 8, 16 and 24 weeks. Results Symptoms of depression and anxiety decreased significantly over time for both groups. However, there was no statistically significant difference between the two groups (IDS: P = 0.35 and HADS: P = 0.64. The largest, but not significant, effect (d = -0.21 was found for anxiety on T3. In both groups approximately 48% of the patients were recovered from their DSM-IV diagnosis at the final 6 months assessment. Conclusions In summary we could not demonstrate that stepped care for depression and anxiety in general practice was more effective than care as usual. Possible reasons are discussed.

    We aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain. A single-center randomized controlled single-blind trial was performed in a general medical practice in Germany run by a Chinese-born medical doctor trained in western and Chinese medicine. One hundred and fifty outpatients with chronic low back pain were randomly allocated to two groups (78 standardized and 72 individualized acupuncture). Patients received either standardized acupuncture or individualized acupuncture. Treatment encompassed between 10 and 15 treatments based on individual symptoms with two treatments per week. The main outcome measure was the area under the curve (AUC) summarizing eight weeks of daily rated pain severity measured with a visual analogue scale (0 mm = no pain, 100 mm = worst imaginable pain). No significant differences between groups were observed for the AUC (individualized acupuncture mean: 1768.7 (95% CI, 1460.4; 2077.1); standardized acupuncture 1482.9 (1177.2; 1788.7); group difference, 285.8 (-33.9; 605.5) P = 0.080). In this single-center trial, individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain. As a next step, a multicenter noninferiority study should be performed to investigate whether standardised acupuncture treatment for chronic low back pain might be applicable in a broader usual care setting. This trial is registered with ClinicalTrials.gov NCT00758017.

    The purpose is to solve the Linear Quadratic Regulator (LQR) problem with random time sampling. Such a sampling scheme may arise from imperfect instrumentation as in the case of sampling jitter. It can also model the stochastic information exchange among decentralized controllers to name just a few. A practical suboptimal controller is proposed with the nice property of mean square stability. The proposed controller is suboptimal in the sense that the control structure is limited to be linear. Because of i. i. d. assumption, this does not seem unreasonable. Once the control structure is fixed, the stochastic discrete optimal control problem is transformed into an equivalent deterministic optimal control problem with dynamics described by the matrix difference equation. The N-horizon control problem is solved using the Lagrange's multiplier method. The infinite horizon control problem is formulated as a classical minimization problem. Assuming existence of solution to the minimization problem, the total system is shown to be mean square stable under certain observability conditions. Computer simulations are performed to illustrate these conditions.

    We conducted a parallel group randomized controlled trial of children initially aged 2 to 3 y who were caries free, to prevent the children becoming caries active over the subsequent 36 mo. The setting was 22 dental practices in Northern Ireland, and children were randomly assigned by a clinical trials unit (CTU) (using computer-generated random numbers, with allocation concealed from the dental practice until each child was recruited) to the intervention (22,600-ppm fluoride varnish, toothbrush, 50-mL tube of 1,450 ppm fluoride toothpaste, and standardized, evidence-based prevention advice) or advice-only control at 6-monthly intervals. The primary outcome measure was conversion from caries-free to caries-active states. Secondary outcome measures were number of decayed, missing, or filled teeth (dmfs) in caries-active children, number of episodes of pain, and number of extracted teeth. Adverse reactions were recorded. Calibrated external examiners, blinded to the child's study group, assessed the status of the children at baseline and after 3 y. In total, 1,248 children (624 randomized to each group) were recruited, and 1,096 (549 intervention, 547 control) were included in the final analyses. Eighty-seven percent of intervention and 86% of control children attended every 6-mo visit ( P = 0.77). A total of 187 (34%) in the intervention group converted to caries active compared to 213 (39%) in the control group (odds ratio, 0.81; 95% confidence interval, 0.64-1.04; P = 0.11). Mean dmfs of those with caries in the intervention group was 7.2 compared to 9.6 in the control group ( P = 0.007). There was no significant difference in the number of episodes of pain between groups ( P = 0.81) or in the number of teeth extracted in caries-active children ( P = 0.95). Ten children in the intervention group had adverse reactions of a minor nature. This well-conducted trial failed to demonstrate that the intervention kept children caries free, but there was evidence that once

    Objective This study expands previous equine-assisted intervention research by evaluating the effectiveness of therapeutic horseback riding (THR) on self-regulation, socialization, communication, adaptive, and motor behaviors in children with autism spectrum disorder (ASD). Method Participants with ASD (ages 6–16 years; N=127) were stratified by nonverbal IQ standard scores (≤ 85 or > 85) and randomized to one of two groups for 10 weeks: THR intervention or a barn activity (BA) control group without horses that employed similar methods. The fidelity of the THR intervention was monitored. Participants were evaluated within one month pre- and post-intervention by raters blind to intervention conditions and unblinded caregiver questionnaires. During the intervention, caregivers rated participants’ behaviors weekly. Results Intent-to-treat analysis conducted on the 116 participants who completed a baseline assessment (THR n = 58; BA control n = 58) revealed significant improvements in the THR group compared to the control on measures of irritability (primary outcome) (p=.002; effect size [ES]=.50) and hyperactivity (p=.001; ES=0.53), beginning by week five of the intervention. Significant improvements in the THR group were also observed on a measure of social cognition (p=.05, ES=.41) and social communication (p=.003; ES =.63), along with the total number of words (p=.01; ES=.54) and new words (p=.01; ES=.54) spoken during a standardized language sample. Sensitivity analyses adjusting for age, IQ, and per-protocol analyses produced consistent results. Conclusion This is the first large-scale randomized, controlled trial demonstrating efficacy of THR for the ASD population, and findings are consistent with previous equine-assisted intervention studies.

    Full Text Available Abstract Background Panic disorder (PD is a common, severe and persistent mental disorder, associated with a high degree of distress and occupational and social disability. A substantial proportion of the population experiences subthreshold and mild PD and is at risk of developing a chronic PD. A promising intervention, aimed at preventing panic disorder onset and reducing panic symptoms, is the 'Don't Panic' course. It consists of eight sessions of two hours each. The purpose of this study is to evaluate the effectiveness of this early intervention – based on cognitive behavioural principles – on the reduction of panic disorder symptomatology. We predict that the experimental condition show superior clinical and economic outcomes relative to a waitlisted control group. Methods/design A pragmatic, pre-post, two-group, multi-site, randomized controlled trial of the intervention will be conducted with a naturalistic follow-up at six months in the intervention group. The participants are recruited from the general population and are randomized to the intervention or a waitlist control group. The intervention is offered by community mental health centres. Included are people over 18 years of age with subthreshold or mild panic disorder, defined as having symptoms of PD falling below the cut-off of 13 on the Panic Disorder Severity Scale-Self Report (PDSS-SR. Primary outcomes are panic disorder and panic symptoms. Secondary outcomes are symptoms of agoraphobia, anxiety, cognitive aspects of panic disorder, depressive symptoms, mastery, health-related quality of life, and cost-effectiveness. We will examine the following variables as potential mediators: cognitive aspects of panic disorder, symptoms of agoraphobia, anxiety and mastery. Potential moderating variables are: socio-demographic characteristics, panic disorder, agoraphobia, treatment credibility and mastery. Discussion This study was designed to evaluate the (cost effectiveness of an

    Full Text Available Background: Postmenopausal hypertension is the most common risk factor of cardiovascular morbidity and mortality. As the exercises training conveys benefits of the setting of secondary prevention of hypertension. High intensity interval training (HIIT emerged as a new form of physical training and presents as therapeutic alternative to patients and health care professionals. This study aimed to investigate the effect of high intensity interval training on endothelial function in postmenopausal hypertension. Methods: Forty six mildly hypertensive postmenopausal women, their ages ranged from (45-55 years old, were randomly allocated to two groups: HIIT group (group-I; n=23 performed a high intensity interval training 3 times a week for 10 weeks at an intensity of (80-85% HR max for 40 minutes and control group (group-II; n=23 remains sedentary during this period. Serum nitric oxide (NO, vascular endothelial growth factor levels (VEGF and blood pressures were measured before and after intervention. Results: A significant reduction in both systolic and diastolic blood pressure values by 9.5% and 7 % respectively, was seen after high intensity interval training which was accompanied by increase in NO and VEGF levels by 43.3% and 15.2 % respectively, while no significant change observed in the control group. Conclusion: High intensity interval training had obvious benefits in improving plasma No, VEGF concentrations and controlling hypertension in postmenopausal women.

    Tinnitus is a subjective sensation of hearing a sound in the absence of an external stimulus, which significantly worsens the quality of life in 15-25% of affected individuals. To assess the effectiveness of acupuncture therapy for tinnitus. Randomized clinical trial ( 2T9T7Q) with 50 participants with tinnitus, divided into two groups: 25 participants in the acupuncture group and 25 participants in the control group. The acupuncture group received acupuncture treatment and the control group received no treatment. After a period of 5 weeks, they were called to perform the final evaluation and the control group received acupuncture treatment for ethical reasons. A statistically significant result was found for the primary outcome, reducing the intensity of tinnitus, with p=0.0001 and the secondary endpoint, showing improvement in quality of life, with p=0.0001. Chinese scalp acupuncture associated with bilateral electroacupuncture demonstrated, in the short term, a statistically significant improvement by reducing the level of tinnitus intensity, as well as improving the quality of life of individuals with tinnitus.

    To determine whether real-time video communication between the first responder and a remote intensivist via Google Glass improves the management of a simulated in-hospital pediatric cardiopulmonary arrest before the arrival of the ICU team. Randomized controlled study. Children's hospital at a tertiary care academic medical center. Forty-two first-year pediatric residents. Pediatric residents were evaluated during two consecutive simulated pediatric cardiopulmonary arrests with a high-fidelity manikin. During the second evaluation, the residents in the Google Glass group were allowed to seek help from a remote intensivist at any time by activating real-time video communication. The residents in the control group were asked to provide usual care. The main outcome measures were the proportion of time for which the manikin received no ventilation (no-blow fraction) or no compression (no-flow fraction). In the first evaluation, overall no-blow and no-flow fractions were 74% and 95%, respectively. During the second evaluation, no-blow and no-flow fractions were similar between the two groups. Insufflations were more effective (p = 0.04), and the technique (p = 0.02) and rate (p Google Glass group than in the control group. Real-time video communication between the first responder and a remote intensivist through Google Glass did not decrease no-blow and no-flow fractions during the first 5 minutes of a simulated pediatric cardiopulmonary arrest but improved the quality of the insufflations and chest compressions provided.

    This study assessed the impact of a course on communication skills for third-year undergraduate dental students at a dental institute in India. A randomized pretest, posttest controlled trial was conducted with all the students from four cohorts of third-year dental undergraduate students, divided into an intervention group (n=30) and a control group (n=30). The course was developed using Kern's six-step approach to curriculum development. Needs assessment was ascertained, and readings, lectures, and role-plays with real and simulated patients were implemented. Encounters of students during two patient interviews (simulated and real) were rated by two raters using a twenty-seven-item dental consultation communication checklist with a rating scale 0 to 3. Students completed a questionnaire regarding their acceptance of the course. A 2×2 (group × time) ANOVA with group as a between-subjects factor (control vs. experimental) and time as a within-subjects factor (pre vs. post) was performed. The two groups did not differ at pretest but differed significantly at posttest. This study showed that simply attending to patients during a clinical course did not improve professional communication skills. In contrast, the implementation of a course on communication skills did improve the students' dentist-patient interactions. Integrating the teaching and development of a relevant, outcome-based course on communication skills provided clear evidence of communication skills acquisition among these dental students. The course could be introduced in other Indian dental schools.

    Efficacy of burping in lowering colic and regurgitation episodes in healthy term babies lacks evidence in literature. We conducted a randomized controlled trial to compare efficacy of burping versus no-burping in 71 mother-baby dyads in community setting. Primary outcome was reduction in event rates of colic and regurgitation episodes over 3 months. Baseline characteristics were similar in two groups. Difference in incidence rates of colic between the control and burping group was 1.57 episodes/infant/100 weeks [95% confidence interval (CI): -0.63 to 3.76]. There was statistically no significant reduction in colic episodes between burping and non-burping study subjects during 3 months of follow-up (adjusted relative risk 0.64; 95% CI: 0.22-1.86, P-value 0.41). Incidence rate difference of regurgitation episodes/infant/week between burping and control group was 4.36 (95% CI: 4.04 to 4.69) and there was statistically significant increase in burping group (adjusted relative risk 2.05; 95% CI: 1.92-2.18, P-value rite of passage, our study showed that burping did not significantly lower colic events and there was significant increase in regurgitation episodes in healthy term infants up to 3 months of follow-up. © 2014 John Wiley & Sons Ltd.

    A healthy lifestyle is important for mothers during the postpartum period. This study was conducted to determine the effects of a lifestyle educational package in primiparous women. This randomized clinical trial was conducted on 220 mothers assigned to two groups using block randomization. In the intervention group, the mothers received face-to-face, phone and SMS counseling and a booklet in addition to routine postpartum training; in the control group, the mothers received only routine training. The Health Behaviors Questionnaire, a Food Frequency Questionnaire and the International Physical Activity Questionnaire were used for data collection. There were no significant differences between the two groups 6 weeks after delivery in terms of physical activity level and nutritional status (P > 0.05) except for the mean consumption of milk and dairy, which was higher in the intervention group (P = 0.041). Training significantly improved certain health behaviors in the intervention group compared to the controls, such as the first time brushing the teeth after delivery, the frequency of sun exposure, the frequency of ventilating the home, keeping warm and iron supplementation. The training provided positively affected certain health behaviors in the mothers; however, it failed to improve their physical activity level and nutritional status. © The Author 2017.

    Use of nonsteroidal anti-inflammatory drugs (NSAIDs) should be avoided in bariatric surgery patients. If use of an NSAID is inevitable, a proton pump inhibitor (PPI) should also be used. To determine the effect of an, compared to care-as-usual, additional intervention to reduce NSAID use in patients who underwent bariatric surgery, and to determine the use of PPIs in patients who use NSAIDs after bariatric surgery. A randomized controlled intervention study in patients after bariatric surgery. Patients were randomized to an intervention or a control group. The intervention consisted of sending a letter to patients and their general practitioners on the risks of use of NSAIDs after bariatric surgery and the importance of avoiding NSAID use. The control group received care-as-usual. Dispensing data of NSAIDs and PPIs were collected from patients' pharmacies: from a period of 6 months before and from 3 until 9 months after the intervention. Two hundred forty-eight patients were included (intervention group: 124; control group: 124). The number of users of NSAIDs decreased from 22 to 18 % in the intervention group and increased from 20 to 21 % in the control group (NS). The use of a PPI with an NSAID rose from 52 to 55 % in the intervention group, and from 52 to 69 % in the control group (NS). Informing patients and their general practitioners by letter, in addition to care-as-usual, is not an effective intervention to reduce the use of NSAIDs after bariatric surgery (trial number NTR3665).

    A four-week, double-blind, randomized, placebo-controlled trial was conducted to assay the effectiveness of Ajwain 10 % (Trachyspermum ammi Sprague) topical cream on neuropathic pain. Intervention encompassed Ajwain 10 % and placebo creams. Ninety-two patients who specifically mentioned daily and nocturnal burning feet were randomly assigned to receive one of those interventions. Presence and decline in patients' numbness, tingling and allodynia were also evaluated. Major outcome measure was alteration in feet burning intensity (final week versus baseline week) regarding to a visual analog scale on a 0-10 cm scale (0 being "no pain", 10 being "worst pain"). Significant reduction in feet burning scores as well as numbness, tingling and allodynia were found in Ajwain group compared to placebo. This trial examining a cream of Ajwain essential oil versus placebo revealed the significance difference between two groups. This medicament can be a good candidate for the alleviation of feet burning, a neuropathic complication.

    Full Text Available Context: Many techniques are used for sedation of colonoscopies. Patient-controlled sedation (PCS is utilizing many drugs or drug combinations. Aims: The aim of this study is to compare the safety and feasibility of propofol/remifentanil versus propofol/alfentanil given to sedate patients undergoing outpatient colonoscopies through a patient-controlled technique. Settings and Design: Controlled randomized and double-blind study. Materials and Methods: A total of 80 patients were randomly divided into two groups; PA group received a combination of propofol/alfentanil and PR group received propofol/remifentanil combination. Patients were monitored for heart rate (HR, blood pressure (BP, oxygen saturation, and Ramsay sedation scale (RSS. Times of the following events were recorded; initiation of sedation, insertion and removal of the colonoscope, recovery and discharge. Five intervals were calculated; time to sedation, procedure time, postprocedure time, procedure room time, and postanesthesia care unit (PACU time. Endoscopist and patient satisfaction scores were obtained. Statistical Analysis Used: Unpaired Student′s t-test was used to compare between the two groups. Paired Student′s t-test was used to compare baseline readings with readings after 30 min of sedation in the same group when needed. Results: Both groups showed slowing of the HR and decrease in mean arterial BP. HR and mean arterial BP were significantly lower 5 and 10 min after initiation of sedation in PR group when compared with PA group. Both HR and mean arterial BP returned to presedation readings 30 min after initiation of sedation in PR group but not in PA group. No differences between the two groups concerning oxygen saturation, RSS, endoscopist and patient satisfaction scores. Postprocedure and PACU times were significantly prolonged in PA group. Conclusion: PCS with either remifentanil/propofol or alfentanil/propofol for patients undergoing outpatient colonoscopy is safe

    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

    Full Text Available BACKGROUND: The objective of this study was to investigate the relationship between different target levels of glucose and the clinical outcomes of patients undergoing cardiac surgery with cardiopulmonary bypass. METHODS: We designed a prospective study in a university hospital where 109 consecutive patients were enrolled during a six-month period. All patients were scheduled for open-heart surgery requiring cardiopulmonary bypass. Patients were randomly allocated into two groups. One group consisted of 55 patients and had a target glucose level of 80-130 mg/dl, while the other contained 54 patients and had a target glucose level of 160-200 mg/dl. These parameters were controlled during surgery and for 36 hours after surgery in the intensive care unit. Primary outcomes were clinical outcomes, including time of mechanical ventilation, length of stay in the intensive care unit, infection, hypoglycemia, renal or neurological dysfunction, blood transfusion and length of stay in the hospital. The secondary outcome was a combined end-point (mortality at 30 days, infection or length of stay in the intensive care unit of more than 3 days. A p-value of 0.05. CONCLUSIONS: In 109 patients undergoing cardiac surgery with cardiopulmonary bypass, both protocols of glycemic control in an intraoperative setting and in the intensive care unit were found to be safe, easily achieved and not to differentially affect clinical outcomes.

    Tonsillectomy has been performed by a number of techniques. This double blind randomized controlled study compares the technique of tissue coblation with bipolar dissection for the removal of tonsils in 10 adult patients with a history of chronic tonsillitis. A significant reduction in post-operative pain and more rapid healing of the tonsillar fossae were found in the side removed by tissue coblation. There were no episodes of primary or secondary haemorrhage on either side. This new technique for tonsil removal warrants further study.

    To compare and evaluate the treatment outcomes of a nurse-led rheumatology clinic and a rheumatologist-led clinic in patients with low disease activity or in remission who are undergoing biological therapy. Patients with chronic inflammatory arthritis treated with biological therapy are usually monitored by rheumatologists. Nurse-led rheumatology clinics have been proposed in patients with low disease activity or in remission. Randomized controlled trial. A 12-month follow-up trial was conducted between October 2009 and August 2011, where 107 patients were randomized into two groups with a 6-month follow-up to a nurse-led rheumatology clinic based on person-centred care (intervention group; n = 53) or to a rheumatologist-led clinic (control group; n = 54). The hypothesis was that the nurse-led clinic outcomes would not be inferior to those obtained from a rheumatologist-led clinic at the 12-month follow-up. The primary outcome was disease activity measured by Disease Activity Score 28. A total of 47 patients in the intervention group and 50 in the control group completed the 12-month trial. The trial revealed no statistically significant differences between groups in mean change of Disease Activity Score 28, Visual Analogue Scales for pain, the Health Assessment Questionnaire, satisfaction with or confidence in obtaining rheumatology care. Patients with stable chronic inflammatory arthritis undergoing biological therapy could be monitored by a nurse-led rheumatology clinic without difference in outcome as measured by the Disease Activity Score 28. © 2013 The Authors.

    Full Text Available Abstract Background Osteoporosis is a growing worldwide problem, with the greatest burden resulting from fractures. Nevertheless, the majority of fractures in adults occur in those with "osteopenia" (bone mineral density (BMD only moderately lower than young normal individuals. Since long-term drug therapy is an expensive option with uncertain consequences and side effects, natural herbal therapy offers an attractive alternative. The purpose of this study is to evaluate the effect on BMD and safety of the Classic Yin and Yang Tonic Formula for treatment of osteopenia and to investigate the mechanism by which this efficacy is achieved. Methods/design We propose a multicenter double-blind randomized placebo-controlled trial to evaluate the efficacy and safety of the Classic Yin and Yang Tonic Formula for the treatment of osteopenia. Participants aged 55 to 75 with low bone mineral density (T-score between -1 and -2.5 and kidney deficiency in TCM will be included and randomly allocated into two groups: treatment group and control group. Participants in the treatment group will be treated with Classic Yin and Yang Tonic Granule, while the controlled group will receive placebo. Primary outcome measure will be BMD of the lumbar spine and proximal femur using dual-energy X-ray absorptiometry. Secondary outcomes will include pain intensity measured with visual analogue scales, quality of life, serum markers of bone metabolism, indices of Neuro-endocrino-immune network and safety. Discussion If the Classic Yin and Yang Tonic Formula can increase bone mass without adverse effects, it may be a novel strategy for the treatment of osteoporosis. Furthermore, the mechanism of the Chinese medical formula for osteoporosis will be partially elucidated. Trial registration This study is registered at ClinicalTrials.gov, NCT01271647.

    Full Text Available Background: Shivering is very uncomfortable and distressing for the patient, anaesthesiologist and the surgeon, especially when the patient is under regional anaesthesia. Aim and Objectives: The present study was designed to evaluate the efficacy of butorphanol and tramadol in the control of shivering under spinal anaesthesia and to compare their side effects. To compare the efficacy, potency, response time, hemodynamic alterations, and adverse effects of intravenously administered tramadol and butorphanol for relief of shivering occurring during spinal anaesthesia. Material and Methods: This randomized prospective study was conducted in 100 patients who developed shivering under spinal anaesthesia during various abdominal, orthopaedic, urological and gynaecological procedures. Patients with fever, acute infections, drug allergy and compromised cardiorespiratory functions were not included in the study. On shivering, patients were randomly allocated in two groups of 50 patients each who received intravenously 1mg of butorphanol or 50 mg of tramadol in a double blinded manner. Control of shivering, time taken for cessation, recurrence, hemodynamic changes, axillary temperatures and side effects were noted and compared for both the groups. Collected data were analysed using Chi square test and Student's unpaired t test. Results: All patients were relieved of shivering after butorphanol, 58% within 1 min, 82% within 3min and 100% within 5 min. Tramadol relieved shivering in 98% of patients, 32% within 1 min, 60% within 3 min, 98% within 5 mins (p<0.05. There was higher incidence of side effects like nausea and vomiting with tramadol (16% and 12% respectively as compared to butorphanol. Conclusion: Both the drugs, tramadol and butorphanol are effective to control shivering after spinal anaesthesia. Butorphanol is better as compared to tramadol in treating shivering under spinal anaesthesia because of its quicker onset of action, higher success rate

    Introduction: Antibiotic resistance is now a serious problem, although it was not so only a few years ago. The need of the hour is to give clear evidence of the efficacy of antibiotic use, or lack thereof, to the surgeon for a procedure as common as mandibular third molar surgery. Aim: This study aimed to evaluate whether postoperative combined amoxicillin and clavulanic acid in mandibular third molar extraction is effective in preventing inflammatory complications. Study and Design: The study was structured as a prospective randomized double-blind placebo-controlled clinical trial. Materials and Methods: A study was designed wherein the 96 units (two bilaterally similar impacted mandibular third molars per head in 48 patients) were randomly assigned to two treatment groups (Group I and Group II). Each patient served as his/her own control. Each patient received 625 mg of combined amoxicillin and clavulanic acid 1 h before surgery. In the case of third molars belonging to Group I, 625 mg of combined amoxicillin and clavulanic acid TDS was continued for 3 days; in Group II, placebo in similar-looking packs was continued for 3 days. The patients were evaluated on the third and seventh postoperative days for signs of clinical infection and for microbial load evaluation. Statistical Analysis: The data between the two groups were statistically analyzed by the two-tailed Fisher's exact test, with a 95% confidence interval. Results: The difference was not statistically significant between the test group and the control group with regard to erythema, dehiscence, swelling, pain, trismus, and infection based on microbial load. The data were statistically significant for alveolar osteitis, with the occurrence of alveolar osteitis (14.58%) in the placebo group. Conclusion: Postoperative antibiotics are recommended only for patients undergoing contaminated, long-duration surgery. PMID:25937728

    Gabapentin is a potentially useful drug in alleviating the hyperexcitatory painful states in the control of opiate dependence in acute detoxification and the stabilization phase. This study aim was to evaluate the effectiveness of gabapentin adds-on methadone therapy on lowering the methadone. This randomized double blind controlled clinical trial conducted at an outpatient rehabilitation clinic. Sixty patients using opium, opium extract and heroin were randomly assigned to two groups (34 in treatment group and 26 in control group); one group was prescribed combination of methadone (40-120 mg) and gabapentin (300 mg) as group A, and the other group was given methadone (40-120) and placebo as group B. The subjects were followed up for three weeks after intervention. There were 60 outpatients including 51 males with the mean age of 40.9±9.2. Daily dose and cumulative dose of methadone during the treatment was found to be significantly higher in group B (73.8±19.5 mg daily vs. 58.9±11 mg daily and cumulatively 1550.7±409.7 mg vs. 238.3±238.2 mg, p= 0.001). When the patients were stratified based on the kind of abused drug, the methadone dose was seen to be significantly reduced in the opium addicted patients in the group A. Group A showed more withdrawal symptoms whereas the most common complain of group B was sedation particularly during the first three days. The results showed that gabapentin is an effective adds-on therapy when is added to methadone. This drug leads to relief of withdrawal symptoms and lower methadone consumption.

    The initial treatment of childhood-onset systemic lupus erythematosus (SLE) is not standardized. Although corticosteroids are the first-line therapy for SLE, long-term, high-dose steroid therapy is associated with various side effects in children. The Japanese Study Group for Renal Disease in Children (JSRDC) has carried out a multi-center, randomized, controlled trial to evaluate the efficacy and safety of corticosteroid and mizoribine (MZB) therapy as an initial treatment for newly diagnosed juvenile SLE. Twenty-eight patients were treated with a combination steroid and MZB (4-5 mg/kg/day) (group S+M) drug therapeutic regimen, while 29 patients were treated with steroid only (group S); both groups were followed up for 1 year. The time to the first flare from treatment initiation was not significantly different between the two groups (Kaplan-Meier method, p = 0.09). During the period when the steroid was given daily (day 0-183), the time to the first flare from treatment initiation was significantly longer in the patients of group S+M than in those of group S (log-rank test, p = 0.02). At the end of the study period, there were no differences in the severity of proteinuria and renal function impairment between the two groups. No patients dropped out of the trial due to adverse events. In conclusion, our combined steroid and MZB drug therapeutic regimen was not shown to be significantly better than the steroid-only therapy as initial treatment for juvenile SLE. Whether MZB administered in a higher dose would be therapeutically advantageous can only be answered by further studies.

    Full Text Available Abstract Background Studies of the efficacy of vitamin C treatment for fatigue have yielded inconsistent results. One of the reasons for this inconsistency could be the difference in delivery routes. Therefore, we planned a clinical trial with intravenous vitamin C administration. Methods We evaluated the effect of intravenous vitamin C on fatigue in office workers. A group of 141 healthy volunteers, aged 20 to 49 years participated in this randomized, double-blind, controlled clinical trial. The trial group received 10 grams of vitamin C with normal saline intravenously, while the placebo group received normal saline only. Since vitamin C is a well-known antioxidant, oxidative stress was measured. Fatigue score, oxidative stress, and plasma vitamin C levels were measured before intervention, and again two hours and one day after intervention. Adverse events were monitored. Results The fatigue scores measured at two hours after intervention and one day after intervention were significantly different between the two groups (p = 0.004; fatigue scores decreased in the vitamin C group after two hours and remained lower for one day. Trial also led to higher plasma vitamin C levels and lower oxidative stress compared to the placebo group (p Conclusion Thus, intravenous vitamin C reduced fatigue at two hours, and the effect persisted for one day. There were no significant differences in adverse events between two groups. High dose intravenous vitamin C proved to be safe and effective against fatigue in this study.

    Death rattle is an extremely distressing symptom for the dying patient and for his environment. The aim of this study was to assess the efficacy of glycopyrronium bromide as compared with scopolamine hydrobromide in alleviating death rattle in terminal cancer patients with cognitive impairment. In a randomized, controlled study design patients were allocated in two groups. Group A received scopolamine hydrobromide in a dose of 0.5 mg intravenously every 6 hours for a period of 12 hours, group B received glycopyrronium bromide 0.4 mg every 6 hours for a period of 12 hours. In addition, standardized sedatives were administered as required and the analgesic therapy continued either orally or, if necessary, subcutaneously or intravenously in equipotent doses. Every 2 hours death rattle was assessed and rated on a scale of 1 to 5 (1 = audible breathing noises, 5 = very severe rattling noises). In addition, restlessness and expressions of pain were assessed and rated on a scale of 1 to 3 (1 = mild, 2 = moderate, 3 = severe). 13 patients were included in the study, 7 patients were allocated to group A and 6 patients to group B. There were no significant differences in demographic data, age, weight and diagnosis distribution between the two groups. Group B demonstrated a significant reduction of death rattle in the first 12 hours (p = 0.029) in comparison to group A. There were no significant differences concerning the side effects (restlessness, expressions of pain) in both groups. Glycopyrronium bromide given in a dose of 0,4 mg every six hours demonstrated a significant reduction of death rattle compared to scopolamine hydrobromide. Concerning side effects (restlessness, expressions of pain) there was no difference between both substances.

    Full Text Available Abstract Background Isotonic saline has been proposed as a safer alternative to traditional hypotonic solutions for intravenous (IV maintenance fluids to prevent hyponatremia. However, the optimal tonicity of maintenance intravenous fluids in hospitalized children has not been determined. The objective of this study was to estimate and compare the rates of change in serum sodium ([Na] for patients administered either hypotonic or isotonic IV fluids for maintenance needs. Methods This was a masked controlled trial. Randomization was stratified by admission type: medical patients and post-operative surgical patients, aged 3 months to 18 years, who required IV fluids for at least 8 hours. Patients were randomized to receive either 0.45% or 0.9% saline in 5.0% dextrose. Treating physicians used the study fluid for maintenance; infusion rate and the use of additional fluids were left to their discretion. Results Sixteen children were randomized to 0.9% saline and 21 to 0.45% saline. Baseline characteristics, duration (average of 12 hours and rate of study fluid infusion, and the volume of additional isotonic fluids given were similar for the two groups. [Na] increased significantly in the 0.9% group (+0.20 mmol/L/h [IQR +0.03, +0.4]; P = 0.02 and increased, but not significantly, in the 0.45% group (+0.08 mmol/L/h [IQR -0.15, +0.16]; P = 0.07. The rate of change and absolute change in serum [Na] did not differ significantly between groups. Conclusions When administered at the appropriate maintenance rate and accompanied by adequate volume expansion with isotonic fluids, 0.45% saline did not result in a drop in serum sodium during the first 12 hours of fluid therapy in children without severe baseline hyponatremia. Confirmation in a larger study is strongly recommended. Clinical Trial Registration Number NCT00457873 (http://www.clinicaltrials.gov/

    To explore the effectiveness of modified sit-to-stand training on balance function in hemiplegic stroke patients. Randomized controlled trial. Rehabilitation medical centre. A total of 50 hemiplegic patients with stroke were randomly assigned to the control and experimental groups (n = 25 for each group). Patients in the control group received the sit-to-stand training with symmetrical foot position, while patients in the experimental group were given the modified sit-to-stand training in which the paretic foot placed posterior. Subjects in both groups received 30 minutes of sit-to-stand training, five times a week, for four weeks. The time and weight-bearing distribution during sit-to-stand movement, the centre of pressure sway length during quiet standing, the centre of pressure sway areas during dynamic standing and Berg Balance Scale were assessed before and after completing the four-week sit-to-stand training. Our data showed significant improvements in standing balance and the sit-to-stand movement for two groups in the post-training compared with the pre-training. After training, the rise time shortened more significantly in the experimental group (mean change, 0.90 ±0.25 seconds) than the control group (mean change, 0.42 ±0.18 seconds). Weight-bearing asymmetry showed significantly greater improvement in the experimental group (mean change, 0.17 ±0.10) than in the control group (mean change, 0.06 ±0.05). Centre of pressure sway length was significantly smaller in the experimental group (mean change, 27.85 ±10.58 cm) than in the control group (mean change, 21.95 ±8.19 cm). Centre of pressure sway areas was significantly larger in the experimental group (mean change, 84.24 ±26.48 cm(2)) than in the control group (mean change, 67.74 ±22.84 cm(2)) (P = 0.027). The Berg Balance Scale was significantly higher in the experiment group (mean change, 8.4 ±3.1) than the control group (mean change, 5.8±2.8). A modified

    The aim of our study was to assess the effectiveness of thoracic manipulation (TM) on patients with chronic neck pain. 120 patients aged between 18 and 55 were randomly allocated into two groups: an experimental group which received TM and a control group without the manipulative procedure. Both groups received infrared radiation therapy (IRR) and a standard set of educational material. TM and IRR were given twice weekly for 8 sessions. Outcome measures included craniovertebral angle (CV angle), neck pain (Numeric Pain Rating Scale; NPRS), neck disability (Northwick Park Neck Disability Questionnaire; NPQ), health-related quality of life status (SF36 Questionnaire) and neck mobility. These outcome measures were assessed immediately after 8 sessions of treatment, 3-months and at a 6-month follow-up. Patients that received TM showed significantly greater improvement in pain intensity (p = 0.043), CV angle (p = 0.049), NPQ (p = 0.018), neck flexion (p = 0.005), and the Physical Component Score (PCS) of the SF36 Questionnaire (p = 0.002) than the control group immediately post-intervention. All these improvements were maintained at the 6-month follow-ups. This study shows that TM was effective in reducing neck pain, improving dysfunction and neck posture and neck range of motion (ROM) for patients with chronic mechanical neck pain up to a half-year post-treatment.

Patients were randomized into two groups: the video group watched video explaining cataract-related consent information and rewatched specific segments of the video at their own discretion, before receiving traditional verbal consent advisement; the control group did not watch the video. Outcomes included patient satisfaction, refusal to consent, time to complete the consent process, and comprehension measured by a ten-item questionnaire. Results. All 80 enrolled patients signed informed consent forms. Compared with the control group, members of the video group exhibited greater satisfaction (65% versus 86%, p = 0.035) and required less time to complete the consent process (12.3 ± 6.7 min versus 5.6 ± 5.4 min, p < 0.001), while also evincing levels of comprehension commensurate with those reported for patients who did not watch the video (accuracy rate, 77.5% versus 80.2%, p = 0.386). Conclusion. The video-assisted informed consent process had a positive impact on patients' cataract surgery experiences. Additional research is needed to optimize patients' comprehension of the video. PMID:28191349

    Self-esteem is an important potential indicator in etiology, diagnosis and treatment of patients with severe mental illness. ECT is a popular treatment for these patients that can effect on their self-esteem and reinforce their problems. The purpose of this study is to determine the effect of supportive nursing care in increasing self esteem of patients receiving ECT. This clinical trial was conducted in the Baharan psychiatric hospital of Zahedan. A total of 70 cases of patients who received ECT were randomly allocated to control (n=35) and intervention (n=35) groups. The data were collected by demographic characteristics questionnaire and Rosenberg Self Esteem Scale (RSES). Intervention group received the supportive nursing care. The control group received only routine treatment. Self esteem level was measured and compared before and after intervention for two groups. The data was analyzed by SPSS using the χ(2), t-test and ANCOVA. RESULTS showed that both groups were homogeneous on the socio- demographic characteristics. The mean self esteem in the intervention group compared with the control group was significantly increased. While controlling the effects of individual and social variables, the result shows significant differences between two groups in the mean scores of self esteem after the intervention. The results suggest that supportive nursing care can have positive effect on self esteem of patients receiving ECT. It is recommended to use this method for increasing self esteem of these patients.

Totally 120 early CP infants were randomly assigned to two groups equally, the treatment group and the control group. All received acupuncture combined with training rehabilitation. Patients in the treatment group adopted acupuncture based on infants development theory, while those in the control group were treated by head acupuncture. Sitting functional points in Gross motor function measure (GMFM) 88 were observed in different groups and infant patients of various types before and after treatment. Root mean square (RMS) signals of sitting correlated muscles (latissimus dorsi, erector spinae, rectus abdominis) were recorded by surface electromyography (sEMG). The effective rate was evaluated by Nimodipine method. Compared with before treatment, sitting functional points were significantly improved in the two groups (Ptreatment, it was higher in the treatment group than in the control group (Ptreatment group after treatment (all Ptreatment group than in the control group (89.29% vs. 77.78%, P<0.05). Infants development theory based acupuncture could effectively elevate dorsi-extensor muscles force, improve sitting position of 8 months to 1 year old CP infants with parafunctional sitting position.

    The main advantages of video assisted thoracoscopic surgery (VATS) include less post-operative pain, rapid recovery, less postoperative complications, shorter hospital stay and early discharge. Although pain intensity is less as compared to conventional thoracotomy but still patients experience upto moderate pain postoperatively. The objective of this study was to assess the efficacy and morphine sparing effect of intercostal nerve block in alleviating immediate post-operative pain in patients undergoing VATS. Sixty ASA I-III patients, aged between 16 to 60 years, undergoing mediastinal lymph node biopsy through VATS under general anaesthesia were randomly divided into two groups. The intercostal nerve block (ICNB group) received the block along with patient control intravenous analgesia (PCIA) with morphine, while control group received only PCIA with morphine for post-operative analgesia. Patients were followed for twenty four hours post operatively for intervention of post-operative pain in the recovery room and ward. The pain was assessed using visual analogue scale (VAS) at 1, 6, 12 and 24 hours. There was a significant decrease in pain score and morphine consumption in ICNB group as compared to control group in first 6 hours postoperatively. There was no significant difference in pain scores and morphine consumption between the two groups after 6 hours. Patients receiving intercostal nerve block have better pain control and less morphine consumption as compared to those patients who did not receive intercostal nerve block in early (6 hours) post-operative period.

    The role that dietary interventions can play in multiple sclerosis (MS) management is of huge interest amongst patients and researchers but data evaluating this is limited. Possible effects of a very-low-fat, plant-based dietary intervention on MS related progression and disease activity as measured by brain imaging and MS related symptoms have not been evaluated in a randomized-controlled trial. Despite use of disease modifying therapies (DMT), poor quality of life (QOL) in MS patients can be a significant problem with fatigue being one of the common disabling symptoms. Effective treatment options for fatigue remain limited. Emerging evidence suggests diet and vascular risk factors including obesity and hyperlipidemia may influence MS disease progression and improve QOL. To evaluate adherence, safety and effects of a very-low-fat, plant-based diet (Diet) on brain MRI, clinical [MS relapses and disability, body mass index (BMI)] and metabolic (blood lipids and insulin) outcomes, QOL [Short Form-36 (SF-36)], and fatigue [Fatigue Severity Scale (FSS) and Modified Fatigue Impact Scale (MFIS)], in relapsing-remitting MS (RRMS). This was a randomized-controlled, assessor-blinded, one-year long study with 61 participants assigned to either Diet (N=32) or wait-listed (Control, N=29) group. The mean age (years) [Control-40.9±8.48; Diet-40.8±8.86] and the mean disease duration (years) [Control -5.3±3.86; Diet-5.33±3.63] were comparable between the two groups. There was a slight difference between the two study groups in the baseline mean expanded disability status scale (EDSS) score [Control-2.22±0.90; Diet-2.72±1.05]. Eight subjects withdrew (Diet, N=6; Control, N=2). Adherence to the study diet based on monthly Food Frequency Questionnaire (FFQ) was excellent with the diet group showing significant difference in the total fat caloric intake compared to the control group [total fat intake/total calories averaged ~15% (Diet) versus ~40% (Control)].

    Random needle embroidery (RNE) is a graceful art enrolled in the world intangible cultural heritage. In this paper, we study the stitch layout problem and propose a controllable stitch layout strategy for RNE. Using our method, a user can easily change the layout styles by adjusting several high-level layout parameters. This approach has three main features:firstly, a stitch layout rule containing low-level stitch attributes and high-level layout parameters is designed;secondly, a stitch neighborhood graph is built for each region to model the spatial relationship among stitches;thirdly, different stitch attributes (orientations, lengths, and colors) are controlled using different reaction-diffusion processes based on a stitch neighborhood graph. Moreover, our method supports the user in changing the stitch orientation layout by drawing guide curves interactively. The experimental results show its capability for reflecting various stitch layout styles and flexibility for user interaction.

    2006-01-01

    The need for strategies able to accurately manipulate quantum dynamics is ubiquitous in quantum control and quantum information processing. We investigate two scenarios where randomized dynamical decoupling techniques become more advantageous with respect to standard deterministic methods in switching off unwanted dynamical evolution in a closed quantum system: when dealing with decoupling cycles which involve a large number of control actions and/or when seeking long-time quantum information storage. Highly effective hybrid decoupling schemes, which combine deterministic and stochastic features are discussed, as well as the benefits of sequentially implementing a concatenated method, applied at short times, followed by a hybrid protocol, employed at longer times. A quantum register consisting of a chain of spin-1/2 particles interacting via the Heisenberg interaction is used as a model for the analysis throughout.

    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.

    Objectives To determine whether pediatric primary care–based programs to enhance parenting and early child development reduce media exposure and whether enhanced parenting mediates the effects. Design Randomized controlled trial. Setting Urban public hospital pediatric primary care clinic. Participants A total of 410 mother-newborn dyads enrolled after childbirth. Interventions Patients were randomly assigned to 1 of 2 interventions, the Video Interaction Project (VIP) and Building Blocks (BB) interventions, or to a control group. The VIP intervention comprised 1-on-1 sessions with a child development specialist who facilitated interactions in play and shared reading through review of videotapes made of the parent and child on primary care visit days; learning materials and parenting pamphlets were also provided. The BB intervention mailed parenting materials, including age-specific newsletters suggesting activities to facilitate interactions, learning materials, and parent-completed developmental questionnaires (Ages and Stages questionnaires). Outcome Measures Electronic media exposure in the home using a 24-hour recall diary. Results The mean (SD) exposure at 6 months was 146.5 (125.0) min/d. Exposure to VIP was associated with reduced total duration of media exposure compared with the BB and control groups (mean [SD] min/d for VIP, 131.6 [118.7]; BB, 151.2 [116.7]; control, 155.4 [138.7]; P=.009). Enhanced parent-child interactions were found to partially mediate relations between VIP and media exposure for families with a ninth grade or higher literacy level (Sobel statistic=2.49; P=.01). Conclusion Pediatric primary care may represent an important venue for addressing the public health problem of media exposure in young children at a population level.

    Dignity therapy (DT) is a brief form of psychotherapy developed for patients living with a life-limiting illness that has demonstrated efficacy in treating several dimensions of end-of-life psychological distress. Our aim was to determine the influence of DT on demoralization syndrome (DS), the desire for death (DfD), and a sense of dignity (SoD) in terminally ill inpatients experiencing a high level of distress in a palliative care unit. A nonblinded phase II randomized controlled trial was conducted with 80 patients who were randomly assigned to one of two groups: the intervention group (DT + standard palliative care [SPC]) or the control group (SPC alone). The main outcomes were DS, DfD, and SoD, as measured according to DS criteria, the Desire for Death Rating Scale, and the Patient Dignity Inventory (PDI), respectively. All scales were assessed at baseline (day 1) and at day 4 of follow-up. This study is registered with http://www.controlled-trials.com/ISRCTN34354086. Of the 80 participants, 41 were randomized to DT and 39 to SPC. Baseline characteristics were similar between the two groups. DT was associated with a significant decrease in DS compared with SPC (DT DS prevalence = 12.1%; SPC DS prevalence = 60.0%; p Dignity therapy had a beneficial effect on the psychological distress encountered by patients near the end of life. Our research suggests that DT is an important psychotherapeutic approach that should be included in clinical care programs, and it could help more patients to cope with their end-of-life experiences.

    To evaluate secnidazole as a single oral dose treatment for bacterial vaginosis in a phase 2 randomized, double-blind, placebo-controlled study. In a phase 2, randomized, double-blind, dose-ranging, placebo-controlled study, women with bacterial vaginosis who met all Amsel criteria (discharge; pH 4.7 or greater; 20% or greater clue cells; positive whiff test) were randomized one to one to one at 24 U.S. centers to 1 or 2 g secnidazole compared with placebo. The primary endpoint was clinical cure (normalization of discharge, amine odor, and clue cells) 21-30 days after treatment. Secondary endpoints included microbiologic cure, defined as a Nugent score of 0-3, and therapeutic cure, defined as meeting criteria for both clinical and microbiologic cure. The modified intent to treat was used for efficacy analyses and included all randomized patients who met the enrollment criteria. Assuming a clinical cure rate of 40% in the active groups and 15% in the placebo group, a sample size of 52 patients per group provided approximately 80% power to detect a significant difference between groups (.05 level [two-sided]) using a Cochran-Mantel-Haenszel test. Between May and September 2014, 215 patients were enrolled. In the intent-to-treat population, the clinical cure rate was 65.3% for the 2-g group, 49.3% for the 1-g group, and 19.4% for the placebo group. The modified intent-to-treat population included 188 women (median age 33 years; 32% with four or more bacterial vaginosis episodes in the previous year; 54% black) with baseline Nugent scores 4 or greater. Clinical, microbiologic, and therapeutic cure rates were 67.7%, 40.3%, and 40.3% for 2 g secnidazole and 51.6%, 23.4%, and 21.9% for 1 g secnidazole compared with 17.7%, 6.5%, and 6.5% for placebo, respectively (Pbacterial vaginosis treatment (Pbacterial vaginosis treatment.

    The existence of non-celiac gluten sensitivity has been debated. Indeed, the intestinal and extra-intestinal symptoms of many patients with irritable bowel syndrome (IBS) but without celiac disease or wheat allergy have been shown to improve on a gluten-free diet. Therefore, this study set out to evaluate the effects of gluten on IBS symptoms. We performed a double-blind randomized placebo-controlled rechallenge trial in a tertiary care hospital with IBS patients who fulfilled the Rome III criteria. Patients with celiac disease and wheat allergy were appropriately excluded. The participants were administered a gluten-free diet for 4 weeks and were asked to complete a symptom-based questionnaire to assess their overall symptoms, abdominal pain, bloating, wind, and tiredness on the visual analog scale (0-100) at the baseline and every week thereafter. The participants who showed improvement were randomly assigned to one of two groups to receive either a placebo (gluten-free breads) or gluten (whole cereal breads) as a rechallenge for the next 4 weeks. In line with the protocol analysis, 60 patients completed the study. The overall symptom score on the visual analog scale was significantly different between the two groups (Pgluten intervention group scored significantly higher in terms of abdominal pain, bloating, and tiredness (Pgluten diet may worsen the symptoms of IBS patients. Therefore, some form of gluten sensitivity other than celiac disease exists in some of them, and patients with IBS may benefit from gluten restrictions.

    Full Text Available Purpose. This trial was performed to investigate the efficacy of laser acupuncture for the alleviation of lower back pain. Methods. This was a randomized, placebo-controlled, double-blind trial. Fifty-six participants were randomly assigned to either the laser acupuncture group (n=28 or the sham laser acupuncture group (n=28. Participants in both groups received three treatment sessions over the course of one week. Thirteen acupuncture points were selected. The visual analogue scale for pain, pressure pain threshold, Patient Global Impression of Change, and Euro-Quality-of-Life Five Dimensions questionnaire (Korean version were used to evaluate the effect of laser acupuncture treatment on lower back pain. Results. There were no significant differences in any outcome between the two groups, although the participants in both groups showed a significant improvement in each assessed parameter relative to the baseline values. Conclusion. Although there was no significant difference in outcomes between the two groups, the results suggest that laser acupuncture can provide effective pain alleviation and can be considered an option for relief from lower back pain. Further studies using long-term intervention, a larger sample size, and rigorous methodology are required to clarify the effect of laser acupuncture on lower back pain.

    Purpose. This trial was performed to investigate the efficacy of laser acupuncture for the alleviation of lower back pain. Methods. This was a randomized, placebo-controlled, double-blind trial. Fifty-six participants were randomly assigned to either the laser acupuncture group (n = 28) or the sham laser acupuncture group (n = 28). Participants in both groups received three treatment sessions over the course of one week. Thirteen acupuncture points were selected. The visual analogue scale for pain, pressure pain threshold, Patient Global Impression of Change, and Euro-Quality-of-Life Five Dimensions questionnaire (Korean version) were used to evaluate the effect of laser acupuncture treatment on lower back pain. Results. There were no significant differences in any outcome between the two groups, although the participants in both groups showed a significant improvement in each assessed parameter relative to the baseline values. Conclusion. Although there was no significant difference in outcomes between the two groups, the results suggest that laser acupuncture can provide effective pain alleviation and can be considered an option for relief from lower back pain. Further studies using long-term intervention, a larger sample size, and rigorous methodology are required to clarify the effect of laser acupuncture on lower back pain.

    The objective of the present study was to evaluate the long-term effectiveness of an exercise program in modifying the exercise behavior of the community-dwelling elderly subjects. This study was a single-blinded randomized controlled trial. The subjects included 52 males and 65 females 65 years of age or over who were randomly assigned to an exercise-intervention group or a health-education group. The stages of change in exercise behavior were evaluated before and one-year after the intervention period. The subjects' physical function (muscle strength, balance, walking speed) and self-efficacy in each domain of the physical function were measured during the intervention period. There were no significant differences in the stages of change before the intervention between the two groups. Significant differences in the stages of change were observed in "relapse" of stages at two points in time between the two groups (pexercise intervention in community-dwelling elderly subjects is effective in preventing "relapse" of exercise behavior over long periods.

    Full Text Available Diabetic foot ulcers are the major complication of diabetes mellitus; 15% of diabetic people suffer from foot ulcers. Phenytoin is used as a topical application in many studies on diabetic foot ulcers and it is found to stimulate the formation of granulation tissue as early as 2-7 days.1 OBJECTIVE The objective of this study was to compare the efficiency of topical phenytoin application on healing in diabetic foot ulcer with control group using conventional wound dressing. METHOD Totally, 100 patients with diabetic foot ulcer attending Thanjavur Government Medical College Hospital are randomized into two groups, assigned regular saline and betadine dressing for the control group. 2 and phenytoin powder application for the study group. Patient with vascular impairment or uncontrolled diabetes are not included. Both study and control group are compared in terms of number of days required for healing, rate of granulations tissue formation. Rate of reduction in mean ulcer surface area. Quality of graft bed. Skin graft take up and serial culture and sensitivity of wound swabs to assess the effect of topical phenytoin on bacterial load. RESULTS The rate of granulation tissue formation was assessed at the end of 2 weeks; 81 to 90% granulation was seen in study group. In study group, 84% cases graft take up was good and 70% in the control group. Graft take up was 72.4% and 58.43% respectively. Hospital stay 21 days in study group and 45 days in control group. CONCLUSION In our present study it was concluded that the rate of granulation tissue formation, overall graft survival and patient compliance was better in topical phenytoin dressing group. 3 as compared to conventional dressing group.4

    Asthma is a chronic inflammatory disorder of the airways. The chronic inflammation causes an associated increase in airway hyperresponsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness, and coughing at night or in the early morning. Most of the studies have reported, as the effects of yoga on bronchial asthma, significant improvements in pulmonary functions, quality of life, and decrease in medication use, but none of the studies has attempted to show the effect of yoga on biochemical changes. To evaluate the effect of yoga on biochemical profile of asthmatics. In the present study, 276 patients of mild to moderate asthma (FEV 1> 60%) aged between 12 to 60 years were recruited from the Department of Pulmonary Medicine, King George's Medical University, U.P., Lucknow, India. They were randomly divided into two groups: Yoga group (with standard medical treatment and yogic intervention) and control group as standard medical treatment (without yogic intervention). At completion of 6 months of the study period, 35 subjects were dropped out, so out of 276 subjects, only 241 subjects completed the whole study (121 subjects from yoga group and 120 subjects from control group). Biochemical assessment was carried out at baseline and after 6 months of the study period. In yoga group, there was significant improvement found in the proportion of hemoglobin and antioxidant superoxide dismutase in comparison to control group and significant decrease was found in total leukocyte count (TLC) and differential leukocytes count in comparison to control group. There was no significant change found in TLC, polymorphs, and monocytes in between group comparison. Yoga group got significantly better improvement in biochemical variables than control group. Result shows that yoga can be practiced as adjuvant therapy with standard inhalation therapy for better outcome of asthma.

    Most studies have reported only minimal reductions in myopia progression with bifocal or progressive multifocal spectacles, although somewhat larger, although mostly still clinically insignificant, effects have been reported in children with nearpoint esophoria and/or accommodative dysfunctions. The CONTROL study was a 1-year, prospective, randomized, clinical trial of bifocal contact lenses for control of myopia in children with eso fixation disparities at near. Eighty-six myopic subjects, aged 8 to 18 years, were enrolled in the study after passing the screening examination. Of these, 79 completed lens assignment and 78 completed the study. The mean refractive error of these 79 subjects was -2.69 ± 1.40D (SD), and all had progressed by -0.50D or more since their last examination. All subjects also had eso fixation disparity at near. Subjects were randomly assigned to wear either Vistakon Acuvue 2 (single-vision soft contact lenses [SVSCLs]) or Vistakon Acuvue Bifocal (bifocal soft contact lenses [BFSCLs]). Bifocal adds were selected to neutralize the associated phoria. Treatment outcomes included cycloplegic autorefraction and axial length, assessed in terms of changes after 6 and 12 months of treatment from pretreatment baseline values. The BFSCLs significantly slowed myopia progression, with statistically significant differences between the treatment groups after 6 months. After 12 months of treatment, the SVSCL group had progressed by -0.79 ± 0.43D compared with -0.22 ± 0.34D for the BFSCL group (cycloplegic objective spherical equivalent, average of two eyes). Corresponding axial length changes were 0.24 ± 0.17 mm and 0.05 ± 0.14 mm, respectively. All of these differences were found to be statistically significant (unpaired t-tests, p 70%) compared with most published results with multifocal spectacles. Further studies are warranted to identify the critical factors and mechanisms underlying this myopia control effect.

    gastrectomy was better than surgery alone (odds ratio 0.56, 95 %CI 0.40-0.79). There was a significant difference between the two groups by u-test (P=0.0008). Sensitivity analysis revealed the same difference (odds ratio 0.81, 95 % CI 0.70-0.94). Of fourteen trials, only three studies were of high quality according to the Jadad-scale (with three score). There was one meta-analysis trial and the others, about ten trials, were of low quality. There was no trial which mentioned samplesize calculation, allocation concealment, intention-to-treat analysis. Most of the thals didn't describe the blind-procedure. There were five trials which detailed the side-effects according to the toxicity grade by WHO standard. The sideeffects halting treatment were haematologic and biochemical toxicity, debilitating nausea and vomiting. There were two patients died of chemotherapy toxicity.CONCLUSION: Based on the review, intravenous chemotherapy after gastrectomy may have positive treatment effect on gastric cancer. However, the evidence is not strong because of the general low methodologic quality of the RCTs.Therefore, we can't make the conclusion that intravenous chemotherapy after gastrectomy may have better treatment effect on gastric cancer than that of surgery alone. Rigorously designed, randomised, double-blind, placebo-controlled trials are required.

    In real world situations, most scheduling problems occur neither as complete off-line nor ascomplete on-line models. Most likely, a problem arises as an on-line model with some partialinformation. In this article, we consider such a model. We study the scheduling problem P(n1,n2),where two groups of jobs are to be scheduled. The first job group is available beforehand. As soon asall jobs in the first group are assigned, the second job group appears. The objective is to minimize thelongest job completion time (makespan). We show a lower bound of 3/2 even for very special cases.Best possible algorithms are presented for a number of cases. Furthermore, a heuristic is proposed forthe general case. The main contribution of this paper is to discuss the impact of the quantity ofavailable information in designing an on-line algorithm. It is interesting to note that the absence ofeven a little bit information may significantly affect the performance of an algorithm.

    The preoperative or intraoperative administration of intravenous magnesium sulfate has been approved as an accepted medication for stabilizing hemodynamic indices during surgeries. Intraoperative blood loss during orthognathic surgery is frequently abundant and sometimes requires blood transfusion. The present trial addressed the efficacy of intravenous magnesium sulfate on deliberating hypotension and bleeding reduction in patients undergoing bimaxillary orthognathic surgery. This randomized double-blinded placebo controlled trial was conducted on 52 consecutive patients who underwent orthognathic surgery. The participants were randomly assigned to two groups receiving intravenous magnesium sulfate 30 mg/kg body weight bolus for 15 minutes immediately before anesthesia induction, followed by 10 mg/kg/hr dissolved in saline via pump infusion (n=26) and the second group received placebo as same bolus volume of normal saline in a 15-minute intravenous infusion which was continued until the end of operation (n=26). Both systolic and diastolic blood pressures were measured before anesthesia induction at baseline, during surgery, and at the end of the surgery. Intraoperative blood loss was also determined. Systolic and diastolic blood pressures did not differ between the two groups at baseline. Although a downward trend of both systolic and diastolic blood pressures was seen during the operation in both groups, the decrease in blood pressures occurred with greater gradient in the group administered magnesium sulfate. Assessing difference in the trend of the changes in systolic and diastolic blood pressures between the two study groups (adjusted for gender, age, mean body mass index, and time of surgery) showed different trends in the changes of blood pressures. No differences were observed in blood loss or blood product requirement between the two groups. The administration of intravenous magnesium sulfate can attenuate both systolic and diastolic blood pressures during

    Many women experience pain during hysterosalpingogram (HSG). This prospective, randomized, double-blinded, placebo-controlled study assessed whether the use of benzocaine spray during HSG is associated with reduced pain as compared with placebo. Thirty women presenting for HSG were enrolled and randomized to either benzocaine or saline spray. Treatment groups were similar in age, race, parity, pre-procedure oral analgesic use and history of dysmenorrhoea and/or chronic pelvic pain. Median change in pain score from baseline to procedure was 50.6mm (-7.4 to 98.8mm) in the benzocaine group and 70.4mm (19.8 to 100mm) in the placebo group. There was no difference between groups after adjusting for history of dysmenorrhoea. There was no difference in resolution of pain in benzocaine versus placebo groups at 5 min post procedure--median pain score difference -11.1 (-90.1 to 18.5) versus -37.0 (-100 to 1.2)--or at 30 min post procedure. Satisfaction scores did not differ by treatment and did not correlate with pain score during the procedure (rho=0.005). The use of benzocaine spray does not significantly improve pain relief during HSG nor does it hasten resolution of pain post HSG. Of interest, patient satisfaction was not correlated with pain. Many women experience pain during hysterosalpingogram (HSG), which is a test used to evaluate the uterine cavity and fallopian tube. We conducted a prospective, randomized, double-blinded, placebo-controlled study to assess whether the use of benzocaine spray during HSG is associated with reduced pain as compared with placebo. Thirty women presenting for HSG were enrolled and randomized to either benzocaine or saline spray. Treatment groups were similar in age, race, previous pregnancies, pre-procedure oral analgesic use and history of dysmenorrhoea (painful periods) and/or chronic pelvic pain. There was no difference in pain scores or resolution of pain between the two groups. Satisfaction scores did not differ by treatment group

    [Purpose] To investigate the effects of transcutaneous electrical nerve stimulation (TENS) on pain in patients with spinal cord injury. [Subjects and Methods] Fifty-two spinal cord injury patients with central pain were randomly allocated into two groups TENS and control with 26 subjects per group. The patients in TENS and control groups were treated with TENS and sham TENS for 20 min (three times a week) for 12 consecutive weeks, respectively. The two group's pain was assessed using visual analog scale (VAS) and the McGill Pain Questionnaire (including pain rating index-total, pain rating index-affective, pain rating index-sensory, present pain intensity, and number of words chosen) before and after the treatment. [Results] After the intervention, we found significant differences in VAS, pain rating index-total, pain rating index-affective, pain rating index-sensory, present pain intensity, and number of words chosen between the TENS group and the control group. [Conclusion] Our results suggest that TENS effectively decreases pain in patients with spinal cord injury.

    Both pharmacological and non-pharmacological interventions have demonstrated efficacy in the management of fibromyalgia (FM). Non-pharmacological interventions however are far less likely to be used in clinical settings, in part due to limited access. This manuscript presents the findings of a randomized controlled trail of an Internet-based exercise and behavioral self-management program for FM designed for use in the context of a routine clinical care. 118 individuals with FM were randomly assigned to either (a) standard care or (b) standard care plus access to a Web-Enhanced Behavioral Self-Management program (WEB-SM) grounded in cognitive and behavioral pain management principles. Individuals were assessed at baseline and again at 6 months for primary endpoints: reduction of pain and an improvement in physical functioning. Secondary outcomes included fatigue, sleep, anxiety and depressive symptoms, and a patient global impression of improvement. Individuals assigned to the WEB-SM condition reported significantly greater improvement in pain, physical functioning, and overall global improvement. Exercise and relaxation techniques were the most commonly used skills throughout the 6 month period. A no-contact, Internet-based, self-management intervention demonstrated efficacy on key outcomes for FM. While not everyone is expected to benefit from this approach, this study demonstrated that non-pharmacological interventions can be efficiently integrated into routine clinical practice with positive outcomes.

    Innovations to improve the delivery of pediatric preventive care are needed. We enrolled children, 0 to 11 years of age, into a factorial, randomized, controlled trial of a tailored, evidence-based, Web site (MyHealthyChild) that provided information on prevention topics before a scheduled well-child visit. There were 2 components of the intervention, namely, parental Web content and provider notification. Parental Web content provided information to parents about prevention topics; provider notification communicated to physicians topics that were of interest to parents. We assigned 887 children randomly to 4 groups (usual care, content only, content and notification, or notification only). Outcomes were determined with telephone follow-up surveys conducted 2 to 4 weeks after the visit. Poisson regression analysis was used to determine the independent effects of each intervention on the number of topics discussed and the number of preventive practices implemented. Parents in the notification/content group and in the notification-only group reported discussing more MyHealthyChild topics with their provider. Parents in the notification/content group and in the content-only group reported implementing more MyHealthyChild topic suggestions (such as use of a safety device). A Web-based intervention can activate parents to discuss prevention topics with their child's provider. Delivery of tailored content can promote preventive practices.

    Full Text Available Objective. To determine if sexual intercourse reduces absorption of vaginal progesterone gel in women and to determine if progesterone is absorbed by the male during intercourse. Study Design. Prospective, randomized, cross over, controlled study of 20 reproductive-aged women and their male sexual partners randomized to receive vaginal progesterone gel (Crinone 8% gel, Actavis Inc., USA or placebo cream. Serum progesterone for both male and female partners were measured 10 hours after intercourse. One week later, subjects were crossed over to receive the opposite formulation. In the third week, women used progesterone gel at night and abstained from intercourse. Results. Serum progesterone was significantly reduced with vaginal progesterone gel + intercourse compared with vaginal progesterone gel + abstinence (P=0.0075. Men absorbed significant progesterone during intercourse with a female partner using vaginal progesterone gel compared to placebo (P=0.0008. Conclusion(s. Vaginal progesterone gel is reduced in women after intercourse which may decrease drug efficacy during luteal phase support. Because men absorb low levels of progesterone during intercourse, exposure could cause adverse effects such as decreased libido. This study is registered under Clinical Trial number NCT01959464.

    To estimate the effects of vaginal pH-balanced gel on vaginal symptoms and atrophy in breast cancer survivors treated with chemotherapy or endocrine therapy. This was a randomized, double-blind, placebo-controlled study. Breast cancer survivors who experienced menopause after chemotherapy or endocrine therapy were voluntarily enrolled and randomly administered vaginal topical pH-balanced gel or placebo three times per week for 12 weeks. Vaginal dryness and dyspareunia were measured by visual analog scale, vaginal health index, and vaginal pH. The endometrium and ovary were evaluated by transvaginal ultrasonography. Among 98 enrolled women, 86 completed the treatment (n=44 and n=42 for the pH-balanced gel group and placebo group, respectively). Vaginal dryness and dyspareunia improved more in the pH-balanced gel group than in the placebo group (baseline mean 8.20 compared with end-point mean 4.23 [P=.001] and 8.23 compared with 5.48 [P=.040], respectively). Vaginal pH-balanced gel reduced the vaginal pH (gel: baseline mean 6.49 compared with end-point mean 5.00; placebo: 6.22 compared with 5.69 [Pvaginal maturation index (gel: 45.5 compared with 51.2; placebo: 46.4 compared with 47.9 [Pvaginal health index (gel: 15.8 compared with 21.1; placebo 14.3 compared with 16.98 [P=.002]). There was no significant difference in adverse effects between the two groups except for mild irritation at the early time of pH-balanced gel administration. Vaginal pH-balanced gel could relieve vaginal symptoms and improve vaginal health in breast cancer survivors who have experienced menopause after cancer treatment.

    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.

    Full Text Available Background/Aim: Oxidative stress plays a major role in the pathogenesis of pancreatitis. Antioxidant therapy in the form of high-dose vitamin has been used for the treatment of severe acute pancreatitis with equivocal results. We wished to evaluate the efficacy and safety of antioxidant (vitamin A, vitamin C, vitamin E therapy in patients with severe acute pancreatitis. Setting and design: This was a single-center, prospective, randomized, open-label with blinded endpoint assessment study of antioxidant therapy, conducted in the emergency department attached to our hospital. Materials and Methods: Thirty-nine patients with severe acute pancreatitis were randomly assigned to antioxidant treatment group (n=19 or a control group (n=20 within 96 hours of developing symptoms. Patients in the antioxidant group received antioxidants (vitamin A, vitamin E, vitamin C in addition to the standard treatment provided to both the groups for a period of 14 days. The primary outcome variable was presence of organ dysfunction at day 7. The secondary outcome variables were length of hospital stay, multiorgan dysfunction (MODS at day 7, recovery at the end of 4 weeks, complications, and mortality. The change in markers of oxidative stress from baseline was also measured. Results: We demonstrated no significant difference in organ dysfunction (P=1.0, MODS (P=0.8, and length of hospital stay (P=0.29 between the two groups. All the patients survived in the antioxidant-treated group, whereas two patients died in the control group. The change in the levels of malondialdehyde, superoxide dismutase, and reduced glutathione were not significantly different in the two groups at day 7. Univariate analysis showed marginal benefit with antioxidant treatment (P=0.034 in patients with severe acute pancreatitis. Conclusions: This randomized study demonstrates that there is no significant benefit from antioxidant therapy in patients with established severe acute pancreatitis.

    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.

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.

    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.

    BACKGROUND: Although cupping remains a popular treatment modality worldwide, its efficacy for most diseases, including hypertension, has not been scientifical y evaluated. OBJECTIVE: We aimed to determine the efficacy of wet-cupping for high blood pressure, and the incidence of the procedure’s side effects in the intervention group. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a randomized control ed trial conducted in the General Practice Department at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between May 2013 and February 2014. There were two groups (40 participants each):intervention group undergoing wet-cupping (hijama) in addition to conventional hypertension treatment, and a control group undergoing only conventional hypertension treatment. Three wet-cupping sessions were performed every other day. MAIN OUTCOME MEASURE: The mean systolic and diastolic blood pressures were measured using a validated automatic sphygmomanometer. The fol ow-up period was 8 weeks. RESULTS: Wet-cupping provided an immediate reduction of systolic blood pressure. After 4 weeks of fol ow-up, the mean systolic blood pressure in the intervention group was 8.4 mmHg less than in the control group (P = 0.046). After 8 weeks, there were no significant differences in blood pressures between the intervention and control groups. In this study, wet-cupping did not result in any serious side effects. CONCLUSION: Wet-cupping therapy is effective for reducing systolic blood pressure in hypertensive patients for up to 4 weeks, without serious side effects. Wet-cupping should be considered as a complementary hypertension treatment, and further studies are needed. TRIAL REGISTRATION: ClinicalTrials.gov Identifier NCT01987583.

    Multiplex PCR (mPCR) directly from blood has been suggested as a promising method for rapid identification of pathogens causing sepsis. This study aimed to investigate whether mPCR has any impact on antimicrobial treatment. Hematological patients with febrile neutropenia were randomized into two groups. In the study group, mPCR was performed as an addition to standard diagnostics, and PCR finding was immediately communicated to the clinicians, thus being available for decision making. In the control group, clinicians were not aware of PCR result. PCR samples were collected simultaneously with clinically indicated blood culture specimens from peripheral vein and/or central venous catheter at fever onset and once again if fever persisted up to 72 h. Overall, 74 patients of the study group and 76 patients of the control group were enrolled and 253 samples collected. Therapy was changed to targeted antimicrobial therapy (AMT) in 12 patients (16.2%) in the study group and in 12 patients (15.8%) in the control group. For patients with changes, the median time to change to the targeted AMT was 21.4 h in the study group and 47.5 h in the control group (p = 0.018). In the study group, 57.1% (8/14) of changes to targeted AMT was due to PCR finding. PCR led to AMT change in 9.5% (7/74) of study group patients, i.e., in 33.3% (7/21) of patients who had positive PCR finding. There were no significant differences in patient outcomes (secondary endpoints). In conclusion, PCR method accelerates change to the targeted AMT in febrile neutropenic patients.

    Full Text Available Abstract Background Total knee arthroplasty (TKA is often associated with a severe local inflammatory reaction which, unless controlled, leads to persistent pain up to one year after surgery. Standard and accelerated rehabilitation protocols are currently being implemented after TKA, but no consensus exists regarding the long-term effects. Biophysical stimulation with pulsed electromagnetic fields (PEMFs has been demonstrated to exert an anti-inflammatory effect, to promote early functional recovery and to maintain a positive long-term effect in patients undergoing joint arthroscopy. The aim of this study was to evaluate whether PEMFs can be used to limit the pain and enhance patient recovery after TKA. Methods A prospective, randomized, controlled study in 30 patients undergoing TKA was conducted. Patients were randomized into experimental PEMFs or a control group. Patients in the experimental group were instructed to use I-ONE stimulator 4hours/day for 60days. Postoperatively, all patients received the same rehabilitation program. Treatment outcome was assessed using the Knee Society Score, SF-36 Health-Survey and VAS. Patients were evaluated pre-operatively and one, two, six and 12 months after TKA. Joint swelling and Non Steroidal Anti Inflammatory Drug (NSAID consumption were recorded. Comparisons between the two groups were carried out using a two-tail heteroschedastic Student’s t-test. Analysis of variance for each individual subject during the study was performed using ANOVA for multiple comparisons, applied on each group, and a Dunnet post hoc test. A p value  Results Pre-operatively, no differences were observed between groups in terms of age, sex, weight, height, Knee-Score, VAS, SF-36 and joint swelling, with the exception of the Functional Score. The Knee-Score, SF-36 and VAS demonstrated significantly positive outcomes in the I-ONE stimulated group compared with the controls at follow-ups. In the I-ONE group, NSAID use was

    The aim of this 2-week study was to examine the effects of self-administered acupressure intervention onlevels of mood of 54 students (34 males and 20 females) majoring in acupuncture and moxibustion medicineat a college located in Fukuoka, Japan. Eligibility criteria were the ability to complete the intervention accurately and no history of psychiatric diseases. The students were randomly assigned to one of the two groups: an intervention group (IG, n = 28) and a control group (CG, n = 26). The IG participants completed fiveacupressure sessions three times a day (morning, noon, and night), involving the application of pressure to six acupuncture points (GB12, SI17, and LI18 according to 2008 World Health OrganizationRegional Office in the Western Pacific standard), three on the left and three on the right side of the neck for 5 s each. The CG participants were requested to spend their time as usual. Self-reported levels of tension-anxiety, depression-dejection, anger-hostility, vigor, fatigue, and confusion over the past week were measured before and after the study as the main outcomes. Side effects were not predicted and not assessed. The retention rate of this trial was 100%. Improvements in mood, defined as a change from baseline to 2 weeks later, were significantly greater in IG. Our results showed that self-administered intervention had the ability to alter mood levels in college students.

    Full Text Available To evaluate the impact of luteal phase support with vaginal progesterone on pregnancy rates in the intrauterine insemination (IUI cycles, stimulated with clomiphene citrate and human menopausal gonadotropin (hMG, in sub fertile couples.This prospective, randomized, double blind study was performed in a tertiary infertility center from March 2011 to January 2012. It consisted of 253 sub fertile couples undergoing ovarian stimulation for IUI cycles. They underwent ovarian stimulation with clomiphene citrate (100 mg and hMG (75 IU in preparation for the IUI cycle. Study group (n = 127 received luteal phase support in the form of vaginal progesterone (400 mg twice a day, and control group (n = 126 received placebo. Clinical pregnancy and abortion rates were assessed and compared between the two groups.The clinical pregnancy rate was not significantly higher for supported cycles than that for the unsupported ones (15.75% vs. 12.69%, p = 0.3. The abortion rate in the patients with progesterone luteal support compared to placebo group was not statistically different (10% vs. 18.75%, p = 0.45.It seems that luteal phase support with vaginal progesterone was not enhanced the success of IUI cycles outcomes, when clomiphene citrate and hMG were used for ovulation stimulation.

    Full Text Available Abstract Background Colorectal cancer is one of the major neoplasms and a leading cause of cancer death worldwide, and new preventive strategies are needed to lower the burden of this disease. Metformin, a biguanide, which is widely used for treating diabetes mellitus, has recently been suggestive to have a suppressive effect on tumorigenesis and cancer cell growth. In a previous study conducted in non-diabetic subjects, we showed that oral short-term low-dose metformin suppressed the development of colorectal aberrant crypt foci (ACF. ACF have been considered as a useful surrogate biomarker of CRC, although the biological significance of these lesions remains controversial. We devised a prospective randomized controlled trial to evaluate the chemopreventive effect of metformin against metachronous colorectal polyps and the safety of this drug in non-diabetic post-polypectomy patients. Methods/Design This study is a multi-center, double-blind, placebo-controlled, randomized controlled trial to be conducted in non-diabetic patients with a recent history of undergoing colorectal polypectomy. All adult patients visiting the Yokohama City University hospital or affiliated hospitals for polypectomy shall be recruited for the study. Eligible patients will then be allocated randomly into either one of two groups: the metformin group and the placebo group. Patients in the metformin group shall receive oral metformin at 250 mg per day, and those in the placebo group shall receive an oral placebo tablet. At the end of 1 year of administration of metformin/placebo, colonoscopy will be performed to evaluate the polyp formation. Discussion This is the first study proposed to explore the effect of metformin against colorectal polyp formation. Metformin activates AMPK, which inhibits the mammalian target of rapamycin (mTOR pathway. The mTOR pathway plays an important role in the cellular protein translational machinery and cell proliferation. Patients with

    Full Text Available Background & Aim: Episiotomy is one of the most common surgical procedures in obstetrics, which requires analgesia. Entonox gas is known to have analgesic and sedative properties. However, no studies have been found on the analgesic effects of Entonox on episiotomy incision. Therefore, this study aimed to compare the effects of Entonox and lidocaine on pain intensity during episiotomy incision in nulliparous women. Materials and Methods: This randomized controlled trial was conducted on 120 term nulliparous women, who met the inclusion criteria. Subjects were selected by randomized sampling and equally divided into two groups of intervention and control (n=60. In the intervention group, Entonox gas was applied two minutes before episiotomy incision until the end of the procedure. On the other hand, the control group received 5 ml of lidocaine 2% as routine care before episiotomy incision. Data were collected using visual analogue scale to compare the study groups in terms of pain intensity. In addition, patient satisfaction with pain management technique during episiotomy and side effects of Entonox were assessed. Data analysis was performed in SPSS version 22 using Mann-Whitney U and Chi-square tests, and P value of less than 0.05 was considered statistically significant. Results: In this study, no significant difference was observed between the intervention and control groups regarding pain intensity (P=0.52. Moreover, no significant difference was observed in the satisfaction level of the two groups (P=0.70. Conclusion: According to the results of this study, Entonox could be used as an effective and noninvasive alternative to lidocaine to reduce pain during episiotomy incision without significant side effects.

    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

    Social dynamics determined by voting in a stochastic environment is analyzed for a society composed of two cohesive groups of similar size. Within the model of random walks determined by voting, explicit formulas are derived for the capital increments of the groups against the parameters of the environment and "claim thresholds" of the groups. The "unanimous acceptance" and "unanimous rejection" group rules are considered as the voting procedures. Claim thresholds are evaluated that are most beneficial to the participants of the groups and to the society as a whole.

    To evaluate the effect of high dose phenobarbital on lipid peroxidation and antioxidant enzymes in perinatal asphyxia. Open label, Randomized controlled trial. Neonatal intensive care unit of a tertiary care teaching hospital. 72 full term inborn neonates with severe birth asphyxia. Neonates were randomized to Study (phenobarbital) group and Control group. The infants in the study group received phenobarbital infusion (40 mg/kg) within first two hours of life while babies in the control group did not receive any phenobarbital. Rest of the management in both the groups was as per the unit protocol for the management of hypoxic ischemic encephalopathy. A cerebrospinal fluid examination was done at 12 ± 2 hours of life to determine the levels of superoxide dismutase, glutathione peroxidise and malonyldialdehyde. 60 neonates were followed up at 1 month of age when a detailed neurological examination was done. Four neonates in the study group and six neonates in the control group died during the study. Two neonates in the study group were lost to follow up. The cerebrospinal fluid lipid peroxides and antioxidant enzymes were significantly lower in the phenobarbital group as compared to the control group. The neurological outcome at one month follow up was found to be comparable between the two groups. Phenobarbital (40 mg/kg) given in the first two hours of life in term neonates with perinatal asphyxia led to a decrease in CSF levels of lipid peroxides and antioxidant enzymes at 12 ± 2 hours of life.

    Full Text Available To evaluate the safety and efficacy of Isosorbide mononitrate (IMN as a cervical ripening agent prior to induction of labour in term pregnant women.A randomized placebo-controlled study was conducted on 100 term singleton pregnancies planned for induction of labour. The participants were randomly assigned to two groups. One group received 40 mg IMN and the other group received 40mg of placebo kept vaginally. The main outcome of this study was to evaluate the efficacy of IMN in cervical ripening based on the change in modified Bishop score and the effect on time duration between the drug insertion and delivery. Safety of isosorbide mononitrate was assessed by measuring variables related to maternal and neonatal outcomes.Baseline demographic characteristics were similar in both groups. The mean change in modified Bishop score after 2 doses of 40mg IMN was insignificant when compared to placebo. Though IMN shortened the time duration between the drug insertion to delivery when compared to placebo, it was statistically insignificant. The need for oxytocin and 2(nd ripening agent was less in IMN group when compared to placebo group but statistically this also proved to be insignificant. It was noted that there was an increase in caesarean deliveries in IMN than in placebo group. IMN did not cause any significant change in maternal hemodynamics and adverse side effects. Though NICU admission and stay was less in IMN than in placebo group, it was statistically insignificant.Though IMN did not cause any maternal and neonatal adverse effects, it was found to be inefficient in comparison to placebo as a cervical ripening agent.

    Full Text Available Abstract Background An acute complication of thyroidectomy is fatal hematoma, which can produce an upper airway obstruction needing immediate intubation or tracheostomy. After neck surgery, we usually apply a pressure dressing with a non-woven, adhesive fabric to reduce bleeding and fluid collection at the operative bed. We conducted a prospective, randomized, controlled study to evaluate a pressure vs. a non-pressure dressing after thyroid surgery by monitoring blood and serum in the operative bed. Methods We studied 108 patients who underwent 116 thyroid surgeries at Srinagarind Hospital, Khon Kaen University, between December 2006 and September 2007. The patients were randomized to either the pressure dressing or non-pressure dressing group. Ultrasound of the neck was performed 24 ± 3 hours after surgery. The volume of fluid collection in the operative bed was calculated. All patients were observed for any post-operative respiratory distress, wound complications, tingling sensation or tetany. Results The distributions of age, sex, surgical indications and approaches were similar between the two groups. There was no statistically significant difference in the volume of fluid collection in the operative bed (p = 0.150 and the collected drained content (p = 0.798. The average time a drain was retained was 3 days. One patient in the pressure dressing group suffered cutaneous bruising while one patient in the non-pressure dressing group developed immediate hemorrhage after the skin sutures. Conclusion Pressure dressing after thyroidectomy does not have any significant impact on decreasing fluid collection at the operative bed. The use of pressure dressing after thyroidectomy may not therefore be justified. Trial Registration NCT00400465, ISRCTN52660978

    Full Text Available Aim: to compare the effectiveness of active laser acupuncture with placebo on reducing pain intensity and improving functional outcome in geriatric patients with knee osteoarthritis (OA. Methods: a double-blind randomized controlled trial was conducted in geriatrics with knee OA at Medical Acupuncture Outpatient Clinic, Integrated Geriatric Outpatient Clinic, Rheumatology Outpatient Clinic of Cipto Mangunkusumo Hospital, Jakarta, during May to October 2015. Sixty two patients with knee OA  were randomly assigned into two groups: active laser acupuncture group or placebo laser acupuncture group. Interventions were carried out using a gallium aluminum arsenide laser device at the ST35 Dubi, ST36 Zusanli, SP9 Yinlingquan, GB34 Yanglingquan and EX - LE - 4 Neixiyan acupuncture points on the affected knee for ten sessions of treatment, i.e. twice a week. Patients were assessed using a visual analogue scale (VAS and Lequesne index at baseline, after four sessions, after nine sessions and at 2 weeks after the treatment had been stopped. Results: the VAS scores were significantly improved in the active laser acupuncture group compared to the placebo group. The evaluation of VAS scores was carried out after four treatment sessions (mean difference: 0.39; p<0.001, after nine treatment sessions (mean difference: 37.48; p<0.001 and at 2 weeks post intervention (mean difference: 39.15; p<0.001. The evaluation also showed significant improvement of Lequesne index after four treatment sessions (mean difference: 4.68; p<0.001, after nine treatment sessions (mean difference: 5.90; p<0.001 and at 2 weeks post intervention (mean difference: 6.48; p<0.001.

    Studies examining the ability of motivational enhancement therapy (MET) to augment education provision among ecstasy users have produced mixed results and none have examined whether treatment fidelity was related to ecstasy use outcomes. The primary objectives of this multi-site, parallel, two-group randomized controlled trial were to determine if a single-session of MET could instill greater commitment to change and reduce ecstasy use and related problems more so than an education-only intervention and whether MET sessions delivered with higher treatment fidelity are associated with better outcomes. The secondary objective was to assess participants' satisfaction with their assigned interventions. Participants (N=174; Mage=23.62) at two Australian universities were allocated randomly to receive a 15-minute educational session on ecstasy use (n=85) or a 50-minute session of MET that included an educational component (n=89). Primary outcomes were assessed at baseline, and then at 4-, 16-, and 24-weeks postbaseline, while the secondary outcome measure was assessed 4-weeks postbaseline by researchers blind to treatment allocation. Overall, the treatment fidelity was acceptable to good in the MET condition. There were no statistical differences at follow-up between the groups on the primary outcomes of ecstasy use, ecstasy-related problems, and commitment to change. Both intervention groups reported a 50% reduction in their ecstasy use and a 20% reduction in the severity of their ecstasy-related problems at the 24-week follow up. Commitment to change slightly improved for both groups (9%-17%). Despite the lack of between-group statistical differences on primary outcomes, participants who received a single session of MET were slightly more satisfied with their intervention than those who received education only. MI fidelity was not associated with ecstasy use outcomes. Given these findings, future research should focus on examining mechanisms of change. Such work may

    The aim of this study was to determine whether 3 days of TENS therapy postoperatively after shoulder operations would result in better pain relief and/or reduced analgesic intake when compared to placebo. The study was carried out randomized, double-blind and placebo controlled. Thirty patients were randomized to two groups. The verum group received TENS SM1AKS 80 Hz 6 mA and the placebo group received TENS SM1AKS 80 Hz 0 mA. The pain was assessed pre-operatively using the Hamburg Pain Adjective List. Premedication and Anaesthesia were standardized. TENS was applied to the patients immediately postoperatively for 8 hours and then on the following days 5 times daily for 45 minutes. The effectiveness was evaluated postoperatively using a visual analogue scale (rest, activity), the Hamburg Pain Adjective List and postoperative analgesic consumption. The visual analogue scale at rest and on activity showed no significant difference between the groups. Postoperative analgesic consumption of morphine hydrochloride in the first 24 hours was at time 8 hours postoperative significantly and at all other time points markedly less in the verum group compared to the placebo group. The sensory secondary scale score of the "Hamburg Pain Adjective List" was significantly lower postoperatively compared to preoperatively in the verum group. We were able to show in this study that TENS applied postoperatively after shoulder surgery clearly reduced analgesic consumption in the first 72 hours. Furthermore there was a significant difference in the pain scores using the "Hamburg Pain Adjective List" in favour of the verum group. TENS applied postoperatively is a effective, simple modality with few side-effects.

    To evaluate the immediate and long-term effects of aerobic treadmill plus Bobath walking training in subacute stroke survivors compared with Bobath walking training alone. Randomized controlled trial. Rehabilitation unit. Fifty patients, first-time supratentorial stroke, stroke interval less than six weeks, Barthel Index (0-100) from 50 to 80, able to walk a minimum distance of 12 m with either intermittent help or stand-by while walking, cardiovascular stable, minimum 50 W in the bicycle ergometry, randomly allocated to two groups, A and B. Group A 30 min of treadmill training, harness secured and minimally supported according to patients' needs, and 30 min of physiotherapy, every workday for six weeks, speed and inclination of the treadmill were adjusted to achieve a heart rate of HR: (Hrmax-HRrest)*0.6+HRrest; in group B 60 min of daily physiotherapy for six weeks. Primary outcome variables were the absolute improvement of walking velocity (m/s) and capacity (m), secondary were gross motor function including walking ability (score out of 13) and walking quality (score out of 41), blindly assessed before and after the intervention, and at follow-up three months later. Patients tolerated the aerobic training well with no side-effects, significantly greater improvement of walking velocity and capacity both at study end (p =0.001 versus p =0.002) and at follow-up (p Bobath walking training in moderately affected stroke patients was better than Bobath walking training alone with respect to the improvement of walking velocity and capacity. The treatment approach is recommended in patients meeting the inclusion criteria. A multicentre trial should follow to strengthen the evidence.

    To test the effectiveness of multiple interventions on increasing the response rate of text messaging for longitudinal data collection. Our cohort included 283 caregivers of children aged 6-12 months who were participating in an anemia program in rural China. Using text messages to collect data on anemia medication adherence, we conducted a delayed randomized controlled trial to test multiple interventions (an additional four reminders; a ¥5.0 (US$0.79) credit reward for replying; and a feedback text message). After a 6-week pilot study with week 7 as the baseline measurement, we randomly allocated all participants into two groups: group 1 (n = 142) and group 2 (n = 141). During weeks 8-11, we introduced the interventions to group 1, and in weeks 12-15 the intervention was introduced to both groups. We compared the response rates between groups and explored factors affecting the response rate. During weeks 8-11, the response rates in group 1 increased and were significantly higher than in group 2 (p0.05) and slightly decreased in group 1. Younger participants or participants who had children with lower hemoglobin concentration were more likely to reply (p = 0.02). Sending four reminders on the second day contributed to only 286 (11.7%) extra text messages. Our study showed that multiple interventions were effective in increasing response rate of text messaging data collection in rural China. Larger multi-site studies are needed to find the most effective way of using these interventions to allow usage of text messaging data collection for health research. © The Author 2014.

    Full Text Available Abstract Background Non-steroidal anti-inflammatory drugs (NSAIDs are recommended for multimodal postoperative pain management. We evaluated opioid-sparing effects and rehabilitative results after perioperative celecoxib administration for total knee arthroplasty. Methods This was a prospective, randomized, observer-blind control study. Eighty patients that underwent total knee arthroplasty were randomized into two groups of 40 each. The study group received a single 400 mg dose of celecoxib, one hour before surgery, and 200 mg of celecoxib every 12 hours for five days, along with patient-controlled analgesic (PCA morphine. The control group received only PCA morphine for postoperative pain management. Visual analog scale (VAS pain scores, active range of motion (ROM, total opioid use and postoperative nausea/vomiting were analyzed. Results Groups were comparable for age, pre-operative ROM, operation duration and intraoperative blood loss. Resting VAS pain scores improved significantly in the celecoxib group, compared with controls, at 48 hrs (2.13 ± 1.68 vs. 3.43 ± 1.50, p = 0.03 and 72 hrs (1.78 ± 1.66 vs. 3.17 ± 2.01, p = 0.02 after surgery. Active ROM also increased significantly in the patients that received celecoxib, especially in the first 72 hrs [40.8° ± 17.3° vs. 25.8° ± 11.5°, p = 0.01 (day 1; 60.7° ± 18.1° vs. 45.0° ± 17.3°, p = 0.004 (day 2; 77.7° ± 15.1° vs. 64.3° ± 16.9°, p = 0.004 (day 3]. Opioid requirements decreased about 40% (p = 0.03 in the celecoxib group. Although patients suffering from post-operative nausea/vomiting decreased from 43% in control group to 28% in celecoxib group, this was not significant (p = 0.57. There were no differences in blood loss (intra- and postoperative between the groups. Celecoxib resulted in no significant increase in the need for blood transfusions. Conclusion Perioperative celecoxib significantly improved postoperative resting pain scores at 48 and 72 hrs, opioid

    Full Text Available Background Traumatic brain injury (TBI is one of the important causes of morbidity and mortality throughout the world, especially in young people. In recent years normobaric hyperoxia has become an important and useful step for recovery and improvement of outcome in TBI. Objectives The purpose of this study was to evaluate the effects of normobaric hyperoxia on clinical neurological outcomes of patients with severe traumatic brain injuries. We used the Glasgow outcome scale (GOS, barthel index, and modified rankin scale (mRS to measure the outcomes of patients with TBI. Patients and Methods Sixty-eight consecutive patients with severe TBI (mean Glasgow coma scale [GCS] score: 7.4 who met the inclusion criteria were entered in this randomized controlled clinical trial. The patients were randomized into two groups, as follows: 1 experimental: received 80% oxygen via mechanical ventilator in the first 6 hours of admission, 2 control: received 50% oxygen by mechanical ventilator in the first 6 hours of admission and then standard medical care. We measured the GOS, Barthel Index, and mRS at the time of discharge from hospital and reassessed these measurements at the 6-month follow-up after injury. Results According to our study, there were no significant sex or age differences between the two groups (P = 0.595 and 0.074. The number of days in the intensive care unit (ICU in the control group and experimental group were 11.4 and 9.4 days, respectively (P = 0.28, while the numbers of days of general ward admission were 13.9 and 11.4 days (P = 0.137 respectively. The status of GOS at time of discharge were severe = 13 and 10, moderate = 16 and 19, and low = 5 and 5 in the control and experimental groups, respectively (P = 0.723; 6 months after injury, the scores were as follows: moderate = 16 and 9, low = 15 and 25, and severe = 3 and 0 (P = 0.024. The Barthel index scores in the control and experimental groups were 59.7 and 63.9 at time of discharge (P

    2006-09-01

    Full Text Available Abstract Background Annually, more than 90000 surgical procedures of the thyroid gland are performed in Germany. Strategies aimed at reducing the duration of the surgical procedure are relevant to patients and the health care system especially in the context of reducing costs. However, new techniques for quick and safe hemostasis have to be tested in clinically relevance randomized controlled trials before a general recommendation can be given. The current standard for occlusion of blood vessels in thyroid surgery is ligatures. Vascular clips may be a safe alternative but have not been investigated in a large RCT. Methods/design CLIVIT (Clips versus Ligatures in Thyroid Surgery is an investigator initiated, multicenter, patient-blinded, two-group parallel relevance randomized controlled trial designed by the Study Center of the German Surgical Society. Patients scheduled for elective resection of at least two third of the gland for benign thyroid disease are eligible for participation. After surgical exploration patients are randomized intraoperatively into either the conventional ligature group, or into the clip group. The primary objective is to test for a relevant reduction in operating time (at least 15 min when using the clip technique. Since April 2004, 121 of the totally required 420 patients were randomized in five centers. Discussion As in all trials the different forms of bias have to be considered, and as in this case, a surgical trial, the role of surgical expertise plays a key role, and will be documented and analyzed separately. This is the first randomized controlled multicenter relevance trial to compare different vessel occlusion techniques in thyroid surgery with adequate power and other detailed information about the design as well as framework. If significant, the results might be generalized and may change the current surgical practice.

    Full Text Available Aims: This study aimed to investigate the effect of 6-month physical exercise with a multicomponent cognitive program (MCP on the cognitive function of older adults with moderate to severe Alzheimer's disease (AD. Methods: We included 33 participants with AD in a 6-month randomized controlled trial. The intervention group participated in physical exercise and received a MCP. The control group received only the MCP. Before and after the intervention, cognitive outcomes were assessed using the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-cog, Mini-Mental State Examination, and the Clock Drawing Test. Physical performance was evaluated by exercise time, the number of pedal rotation, total load, grip strength, and the Berg Balance Scale (BBS. Results: In all cognitive measures, there were no significant improvements between the two groups after 6 months in the baseline value-adjusted primary analysis. However, the ADAS-cog score was significantly lower between the two groups in secondary analysis adjusted for baseline value, age, sex, and education years. All physical outcomes were significantly higher in the intervention group except for total load compared with baseline measurements. Conclusion: This study indicates that it is possible to improve cognitive function in older adults with moderate to severe AD through 6-month physical exercise with a multicomponent cognitive intervention.

    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.

    This simulation trial aimed to compare the quality of cardiopulmonary resuscitation (CPR) with and without the newly-developed CPR support application on smartphones. In this trial, participants were randomly assigned to either the CPR support application group or the control group, stratified by sex and previous CPR training. Participants' CPR skills were evaluated by a 2-min case-based scenario test using the Leardal Resusci Anne PC Skill reporting Manikin System(®). The outcome measures were the proportion of chest compressions performed in each group and the number of total chest compressions and appropriate chest compressions performed during the 2-min test period. A total of 84 participants were enrolled and completed the protocol. All participants in the CPR support application group performed chest compressions, compared with only 31 (75.6%) in the control group (Psmartphones contributed to increasing the implementation rate and the number of total chest compressions performed and may assist in improving the survival rate for out-of-hospital cardiac arrests (UMIN000004740).

    Full Text Available BACKGROUND: Dyskinesias are some of the major motor complications that impair quality of life for patients with Parkinson's disease. The purpose of the present study was to investigate the efficacy of amantadine in Parkinson's disease patients suffering from dyskinesias. METHODS: In this multi-center, double-blind, randomized, placebo-controlled, cross-over trial, 36 patients with Parkinson's disease and dyskinesias were randomized, and 62 interventions, which included amantadine (300 mg/day or placebo treatment for 27 days, were analyzed. At 15 days after washout, the treatments were crossed over. The primary outcome measure was the changes in the Rush Dyskinesia Rating Scale (RDRS during each treatment period. The secondary outcome measures were changes in the Unified Parkinson's Disease Rating Scale part IVa (UPDRS-IVa, dyskinesias, part IVb (motor fluctuations, and part III (motor function. RESULTS: RDRS improved in 64% and 16% of patients treated with amantadine or placebo, respectively, with significant differences between treatments. The adjusted odds-ratio for improvement by amantadine was 6.7 (95% confidence interval, 1.4 to 31.5. UPDRS-IVa was improved to a significantly greater degree in amantadine-treated patients [mean (SD of 1.83 (1.56] compared with placebo-treated patients [0.03 (1.51]. However, there were no significant effects on UPDRS-IVb or III scores. CONCLUSIONS: Results from the present study demonstrated that amantadine exhibited efficacious effects against dyskinesias in 60-70% of patients.

    Nonsteroidal anti-inflammatory drugs are a standard treatment option for muscle strain; however, side effects persist. This clinical trial was designed to compare the efficacy of Plai cream compared to placebos in adult patients with muscle strain. In this randomized, double-blind, placebo-controlled trial, 140 participants aged over 18 years with muscle strain were randomized to receive either Plai cream (n = 70 patients, treatment group) or placebos (n = 70 patients, control group) . Outcome assessments included the visual analog scale (VAS), quality of life (QoL), the amount of remaining cream, and the number of acetaminophen tablets used. After 2 weeks, the mean pain scores following treatment with both Plai cream and placebos in patients with muscle strain decreased from baseline to the end of the study at week 2. However, no significant difference for VA S score was found. The QoL of the two groups showed improvements in QoL as witnessed by increased mean QoL scores from baseline to week 2; however, these differences were not statistically significant. In general, mean QoL scores above 50 indicate good quality of life. The amount of Plai cream used reduced from baseline to week 2, but no significant difference in the amount of cream remaining was found between the two groups at each visit. Similarly, the number of acetaminophen tablets used was not statistically different between the treatment and control groups. There was no difference in pain reduction in the 2-week period between patients with muscle strain using Plai cream and those given placebos, but Plai cream tended to reduce pain in the long term. No side effects were found from Plai cream, so this non-invasive treatment may be offered to patients.

    The purpose of this study was to determine the efficacy of fluoride varnish (5% sodium fluoride, Duraphat(®), Colgate) in reverting white spot lesions (WSLs) after fixed orthodontic treatment. This study was a randomized, parallel group, controlled clinical trial. Using saline solution as control, 110 participants (mean age ± standard deviation: 16.6 ± 3.2 years) ranging from 12 to 22 years old were randomly assigned to either the test group (group 1) or the control group (group 2). Application of fluoride varnish or saline was applied onto tooth surfaces with WSLs every month during the first 6 months after debonding. The labial (buccal) surfaces of the teeth were assessed by the use of a DIAGNOdent pen (DD) at the baseline, 3- and 6-month follow-up visits. After 6 months, 96 subjects with a total of 209 study teeth (47 subjects, 104 teeth in group 1; 49 subjects, 105 teeth in group 2) remained. The WSLs had a mean DD reading at baseline of 17.66 ± 5.36 in group 1 and 16.19 ± 5.70 in group 2, which decreased by 5.78 and 2.44, respectively, at the 3-month follow-up visit and decreased by 7.56 and 3.09, respectively, at the 6-month follow-up visit. The mean baseline DD readings in the two groups were similar (t test, P > 0.05). There was statistically significant differences between the mean DD readings of the two groups at the 3-month (P orthodontic treatment.

    Full Text Available Introduction: Pain has been pointed out as one of the concerns of cardiac surgery patients. Acute pain management has been a challenge for health professionals and several regiments have been described. We designed this study to evaluate the effectiveness of pain control with patient-controlled analgesia (PCA versus conventional nurse-controlled analgesia (NCA during the postoperative period in the intensive care unit (ICU after coronary artery bypass graft (CABG surgery. Methods: In this randomized clinical trial, 80 elective CABG candidates were selected by convenience sampling. They were randomly allocated to two groups to receive either PCA or NCA. PCA plus continuous infusion of morphine started immediately after transferring the patients to the ICU. NCA was based on intravenous injections of morphine on demand. Pain was assessed using a verbal rating scale (VRS. Sedation level and morphine consumption were also evaluated from extubation until 48 hours after surgery. Data was analyzed using SPSS13. Results: VRS scores were higher in the NCA group compared to the PCA group [3.27 (1.17 vs. 0.75 (0.66; p < 0.001]. Morphine consumption was significantly higher in the PCA group compared to the NCA group [28.43 (7.15 mg vs. 8.37 (5.36 mg; p < 0.001]. PCA was safe and respiratory depression was not observed in any of the subjects. Mean sedation scores did not differ between the two groups. Conclusion: PCA with background infusion of morphine increases morphine consumption and improves pain relief. It appears to be superior to NCA and can be recommended for patients after CABG surgery.

  20. Challenges in randomized controlled trials and emerging multiple sclerosis therapeutics.

    The remarkable global development of disease-modifying therapies (DMTs) specific for multiple sclerosis (MS) has significantly reduced the frequency of relapse, slowed the progression of disability, and improved the quality of life in patients with MS. With increasing numbers of approved DMTs, neurologists in North America and Europe are able to present multiple treatment options to their patients to achieve a better therapeutic outcome, and in many cases, no evidence of disease activity. MS patients have improved accessibility to various DMTs at no or minimal out-of-pocket cost. The ethical guidelines defined by the Edinburgh revision of the Declaration of Helsinki strongly discourage the use of placebo control groups in modern MS clinical trials. The use of an active comparator control group increases the number of participants in each group that is essential to achieve statistical significance, thus further increasing the difficulty of completing randomized controlled trials (RCTs) for the development of new MS therapies. There is evidence of a high prevalence of MS and a large number of patients in Asia. The belief of the existence of Asian types of MS that are distinct from Western types, and regulatory policies are among the reasons why DMTs are limited in most Asian countries. Lack of access to approved DMTs provides a good opportunity for clinical trials that are designed for the development of new MS therapies. Recently, data from RCTs have demonstrated excellent recruitment of participants and the completion of multi-nation and single-nation MS trials within this region. Recent studies using the McDonald MS diagnostic criteria carefully excluded patients with neuromyelitis optica (NMO) and NMO spectrum disorder, and demonstrated that patients with MS in Asia have clinical characteristics and treatment responses similar to those in Western countries.

    Full Text Available Abstract Background: Cardiovascular diseases are the most prevalent disorders in developed countries and heart failure is the major one among them. This disease is caused by numerous factors and one of the most considerable risk factors is unhealthy lifestyle. So the aim of this research was to study the effect of family-center empowerment model on the lifestyle of heart failure patients. Methods: This is a randomized controlled clinical trial on 70 heart failure patients referring to Hazrate Fatemeh heart clinic in Shiraz. After convenience sampling the patients were divided into two control and intervention groups using block randomization Method. The intervention based on family-center empowerment model was performed during 5 sessions. Research tools are lifestyle and demographic information questionnaires. Results: Both intervention and control groups were similar regarding their demographic information (P>0.001.Before the intervention on lifestyle, all measures of the two groups were equal (P>0.001 but after the intervention; statistically significant differences were reported in all dimensions of lifestyle, the total lifestyle score in the intervention group was 70.09±16.38 and in the control group -6.03±16.36 (P<0.001. Conclusion: Performing the family-center empowerment model for heart failure patients is practically possible, leading to improvement or refinement of their and their families’ lifestyle.

    2015-03-01

    Full Text Available Objectives: A vertebral compression fracture (VCF is characterized by back pain and fracture of a vertebral body on spinal radiography. VCFs of the thoraco lumbar spine are common in the elderly. In general, appropriate analgesics should be prescribed to reduce pain and, thus, promote early mobilization. The ideal treatment approach for VCFs has not been determined. In Korea, acupuncture and herbal medication have been used to treat VCFs for many years. There is empirical evidence that acupuncture might benefit patients with a VCF. However, no randomized, controlled, clinical trials evaluating the efficacy and the safety of acupuncture for treating a VCF have been published. Therefore, we designed a randomized, controlled, pilot, clinical trial to obtain information for the design of a further full scale trial. Methods: A five week protocol for a randomized, controlled, pilot, clinical trial is presented. Fourteen patients will be recruited and randomly allocated to two groups: a control group receiving interlaminar epidural steroid injections once a week for three weeks, and an experimental group receiving interlaminar epidural steroid injections plus acupuncture treatment (three acupuncture sessions per week for three weeks, nine sessions in total. The primary outcomes will be the pain intensity (visual analogue scale and PainVisionTM system. The secondary outcome measurements will be the answers on the short form McGill pain questionnaire and the oswestry disability index. Assessments will be made at baseline and at one, three, and five weeks. The last assessment (week five will take place two weeks after treatment cessation. This study will provide both an indication of feasibility and a clinical foundation for a future large scale trial. The outcomes will provide additional resources for incorporating acupuncture into existing treatments, such as nonsteroidal anti-inflammatory medications, narcotics and vertebral augmentation.

    There is controversy over the need for electrocauterization of the patella in non-resurfacing total knee arthroplasty (TKA). We investigated whether this procedure is beneficial through a prospective randomized controlled trial. Fifty patients who underwent electrocautery were compared with 50 patients who did not undergo this procedure. We determined cartilage status, preoperative and postoperative American Knee Society (AKS) score, the Western Ontario and McMaster Universities score (WOMAC) and the Patellofemoral (PF) scores for a minimum of 5 years. The two groups did not differ significantly in demographics, intraoperative cartilage status, or preoperative or postoperative outcomes. No complications were detected in either group. We found no benefits of electrocautery of the patella in patellar non-resurfacing TKA up to 5 years. Copyright © 2015 Elsevier Inc. All rights reserved.

    The paper analyzes behavioral patterns of mentors while using different mentoring devices to demonstrate the feasibility of multi-platform mentoring. The fundamental differences of devices supporting telementoring create threats for the perception and interpretation of the transmitted video, highlighting the necessity of exploring hardware usability aspects in a safety critical surgical mentoring scenario. Three types of devices, based on the screen size, formed the arms for the randomized controlled trial. Streaming video recordings of a laparoscopic procedure to the mentors imitated the mentoring scenario. User preferences and response times were recorded while participating in a session performed on all devices. Median response to a mentoring request times were similar for mobile platforms; expected durations were considerably longer for stationary computer. Ability to perceive and identify anatomical structures was insignificantly lower on small sized devices. Stationary and tablet platforms were nearly equally preferred by the most of participants as default telementoring hardware. As a side effect, incompatibility of daily duties of the surgeons in the hospital and telementoring responsibilities while implementing systems locally was identified. Scaling up the use of the service in combination with the organizational changes of clinical staff looks like a promising solution. The trial demonstrated the feasibility of using all three types of devices for the purpose of mentoring, allowing users to choose the preferred platform. The paper provided initial results on the quality assurance of telementoring systems imposed by the regulatory documents. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Many randomized controlled trials (RCTs) of neuropsychiatric conditions involve cognitive outcome measures; however, validity of cognitive data relies on adequate effort during testing, and such screening is seldom performed. Given well-established rates of 10 to 30% poor effort in clinical settings, this is not a trivial concern. This preliminary study evaluated effort during cognitive testing in an RCT of omega-3 supplementation to reduce suicidality in a high-risk psychiatric population. An interim analysis of sustained attentions measures from the Connors Performance Test (CPT-2) at baseline for the first 60 participants was conducted. Previously validated cut points to detect insufficient effort on the CPT-2 were applied. At baseline, 12% (7) were identified as giving poor effort. Follow-up analyses indicated less psychiatric distress and suicidality among those who gave poor effort. Results suggest comparable likelihood of a poor effort on cognitive testing in clinical and RCT participation. Reduced psychiatric distress in the poor effort group raises concern regarding interpretation of other measures. The importance of screening cognitive data for effort in RCTs is highlighted. Future studies will examine effort at follow-up visits, and explore relationships to attrition, adherence, and response to treatment. Copyright © 2016 John Wiley & Sons, Ltd.

    The purpose of this study was to compare the chemomechanical caries-removal system (Carisolv) with high-speed excavation in cavitated occlusal caries of primary molars. Design and setting. The study was a randomized controlled, clinical trial in which the two techniques were compared in each subject. Participants were chosen from public schools, in Maracaibo County, Zulia State, Venezuela. The sample consisted of 80 primary molars selected from 40 children (mean age 7.7+/-0.7 years). Each patient had at least two contralateral primary molars with cavitated occlusal caries and approximately equal-size access to lesions. The outcome variables were: clinically complete caries removal, size of the opening of the cavity, volume of carious tissue removed, pain during caries removal, anaesthesia requested by the patient, caries-removal time, and behaviour and preference of patients. All treated molars were clinically caries free whichever caries-removal procedure was used. When Carisolv' was used the final cavity entrance sizes were smaller (Premoved was less (Premoval was three times longer (7.51+/-1.83 min, Premoval of occlusal dentinal caries in cavitated primary molars; it is more conservative of dental tissue and appeared to be more comfortable for most patients, although the clinical time spent is longer than when using high-speed excavation.

    Environmental testing is an important engineering discipline which aims at simulating the effect of the environmnet on a given structure, item or system. A particular environment is the vibratory one. From development to qualification, engineering systems subject to harsh dynamic environments have to be tested in order to ensure their capability to withstand vibrations. To this end, there exist a wealth of test stadards which impose strict pass/fail criteria. However, these methods are rather dated and the testing community is constantly striving to update the standards to account for new technologies and ever more stringent requirements. Currently, the standard specify to carry out vibration tests along one axis at the time, that is using a Single-Input-Single-Ouput (SISO) or a Single-Input- Multiple-Ouput (SIMO) approach. However, there are a number of significant advanteges in using a Multiple- Input-Multiple-Ouput (MIMO) apporach. In this paper are presented the results of an experimental campaign aimed at assessing the capabilty of the new MIMO Random control developed at LMS.

    Full Text Available In order to investigate the therapeutic potential of acupuncture on patients with functional dyspepsia (FD, patients were randomized to receive acupuncture at classic acupoints with manipulations (treatment group versus acupuncture at nonacupoints without manipulation (control group once every other day, three times a week, for one month and were followed up for three months. The primary outcomes included dyspeptic symptoms, quality of life, and mental status. The secondary outcomes included the fasting serum gastrin concentration, and frequency and propagation velocity of gastric slow waves. Sixty patients with FD were included, among whom, four dropped out. After one month's treatment, patients with FD showed significant improvements in primary (in both groups and secondary (in the eight patients of the treatment group outcomes as compared with baseline (P=0.0078 to <0.0001; treatment group has better outcomes in all primary outcome measures (P<0.0001 except for SDS (P=0.0005. Improvements on dyspeptic symptoms persist during follow-up (better in the treatment group. Acupuncture with manual manipulation had better effects on improving dyspeptic symptoms, mental status, and quality of life in patients with FD. These effects may be related to the increased frequency and propagation speed of gastric slow waves and serum gastrin secretion.

    The need to increase data transfer rates constitutes a key challenge in modern information-driven societies. Taking advantage of the transverse spatial modes of light to encode more information is a promising avenue for both classical and quantum photonics. However, to ease access to the encoded information, it is essential to be able to sort spatial modes into different output channels. Here, we introduce a way to customize the sorting of arbitrary spatial light modes. Our method relies on the high degree of control over random scattering processes by preshaping of the phase structure of the incident light. We demonstrate experimentally that various sets of modes, irrespective of their specific modal structure, can be transformed to a broad range of output channel arrangements. Thus, our method enables full access to all of the information encoded in the transverse structure of the field; for example, azimuthal and radial modes. We also demonstrate that coherence is retained in this complex mode transformation, which opens up applications in quantum and classical information science.

    Posture, gait and balance problems are very disabling symptoms in Parkinson's disease (PD). An increased stride-to-stri de variability, reduction of automaticity and asymmetry of lower limbs function characterize parkinsonian gait. These features predispose to freezing of gait (FOG), which often leads to falls. The aim of this study was to evaluate how the modulation of asymmetry through physiotherapy might improve gait and reduce FOG, thus preventing falls. Twenty-eight PD patients entered a double-blind pilot feasibility controlled study and were evaluated at baseline and after 3 months of a rehabilitative program (performed twice a week) by means of the motor part of the Unified Parkinson's Disease Rating Scale (UPDRS-III), Gait and Falls Questionnaire, Tinetti balance and gait scale, Short Physical Performance Battery (SPPB), European Quality of Life questionnaire. Patients were randomly assigned to three treatment arms: (1) worst side improvement; (2) best side improvement; (3) standard therapy. All study arms showed a significant improvement of the Tinetti and SPPB scores. BSI led to a greater improvement than ST in terms of UPDRS-III (p = 0.01); Tinetti total score (p = 0.05) and Tinetti gait subscore (p = 0.01). Our study confirms the efficacy of physical therapy in the treatment of PD and, more importantly, suggests that specific intervention tailored on individual feature (e.g., asymmetry of motor condition) might be even more effective than standard rehabilitative programs.

    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.

    Randomized controlled trials (RCTs) are the hallmark of evidence-based medicine and form the basis for translating research data into clinical practice. This review summarizes commonly applied designs and quality indicators of RCTs to provide guidance in interpreting and critically evaluating clinical research data. It further reflects on the principle of equipoise and its practical applicability to clinical science with an emphasis on critical care and neurological research. We performed a review of educational material, review articles, methodological studies, and published clinical trials using the databases MEDLINE, PubMed, and ClinicalTrials.gov. The most relevant recommendations regarding design, conduction, and reporting of RCTs may include the following: 1) clinically relevant end points should be defined a priori, and an unbiased analysis and report of the study results should be warranted, 2) both significant and nonsignificant results should be objectively reported and published, 3) structured study design and performance as indicated in the Consolidated Standards of Reporting Trials statement should be employed as well as registration in a public trial database, 4) potential conflicts of interest and funding sources should be disclaimed in study report or publication, and 5) in the comparison of experimental treatment with standard care, preplanned interim analyses during an ongoing RCT can aid in maintaining clinical equipoise by assessing benefit, harm, or futility, thus allowing decision on continuation or termination of the trial.

    Fibromyalgia (FM) is characterized by widespread pain and co-morbid symptoms such as fatigue and depression. For FM, medical treatments alone appear insufficient. Recent meta-analyses point to the utility of cognitive behaviour therapy (CBT), but effects are moderate. Within the continuous development of CBT, the empirical support for acceptance and commitment therapy (ACT) has increased rapidly. ACT focuses on improving functioning by increasing the patient's ability to act in accordance with personal values also in the presence of pain and distress (i.e., psychological flexibility). However, no study has yet explored the utility of ACT in FM. To evaluate the efficacy of ACT for FM and the role of psychological inflexibility as a mediator of improvement. In this randomized controlled trial, ACT was evaluated in comparison to a waiting list control condition. Forty women diagnosed with FM participated in the study. Assessments were made pre- and post-treatment and at 3 months of follow-up. The ACT intervention consisted of 12 weekly group sessions. Significant differences in favour of ACT were seen in pain-related functioning, FM impact, mental health-related quality of life, self-efficacy, depression, anxiety and psychological inflexibility. Changes in psychological inflexibility during the course of treatment were found to mediate pre- to follow-up improvements in outcome variables. The results correspond with previous studies on ACT for chronic pain and suggest the utility of ACT for FM as well as the role of psychological inflexibility as a mediator of improvement. © 2012 European Federation of International Association for the Study of Pain Chapters.

    The aim of this study was to assess the efficacy of adding a cycle of phytothermotherapy (a traditional treatment with fermenting grass used in Trentino-Alto Adige, Italy) to the usual drug treatment, in patients with primary symptomatic osteoarthritis (OA) of the knee, hip, or lumbar spine. In this randomized, single-blind, controlled trial, 218 outpatients were enrolled; 109 patients were treated with a cycle of phytothermotherapy at the thermal resort of Garniga Terme (Trento, Italy) for 10 days; the other 109 patients continued regular outpatient care. Patients were assessed at baseline, after 2 weeks, and after 3 months from the beginning of the study and were evaluated using a visual analogue scale (VAS) for spontaneous pain, a Health Assessment Questionnaire, the Lequesne index for hip and knee osteoarthritis, and the Rolland Morris Questionnaire for lumbar spine OA and symptomatic drug consumption. In patients treated with phytothermotherapy, a significant improvement of VAS and a reduction of nonsteroidal anti-inflammatory drug consumption at the end of treatment and 3 months later were observed. In the control group, no significant differences were noted. The analyses performed separately for each subgroup for OA localization showed that the best results were evident in lumbar spine OA. Concerning tolerability, in the group treated with phytothermotherapy 10% of patients presented side-effects due to treatment, but these were of low intensity and did not interrupt the therapy. In conclusion, the results show beneficial effects of a cycle of phytothermotherapy in patients with OA of the hip, knee, or lumbar spine. Phytothermotherapy may therefore be a useful aid alongside the usual pharmacologic and physiokinesic therapies, or may be used as a valid alternative for patients who do not tolerate pharmacologic treatments.

    Background There is increasing interest in the role of physical exercise as a therapeutic strategy for individuals with Alzheimer’s disease (AD). We assessed the effect of 26 weeks (6 months) of a supervised aerobic exercise program on memory, executive function, functional ability and depression in early AD. Methods and findings This study was a 26-week randomized controlled trial comparing the effects of 150 minutes per week of aerobic exercise vs. non-aerobic stretching and toning control intervention in individuals with early AD. A total of 76 well-characterized older adults with probable AD (mean age 72.9 [7.7]) were enrolled and 68 participants completed the study. Exercise was conducted with supervision and monitoring by trained exercise specialists. Neuropsychological tests and surveys were conducted at baseline,13, and 26 weeks to assess memory and executive function composite scores, functional ability (Disability Assessment for Dementia), and depressive symptoms (Cornell Scale for Depression in Dementia). Cardiorespiratory fitness testing and brain MRI was performed at baseline and 26 weeks. Aerobic exercise was associated with a modest gain in functional ability (Disability Assessment for Dementia) compared to individuals in the ST group (X2 = 8.2, p = 0.02). There was no clear effect of intervention on other primary outcome measures of Memory, Executive Function, or depressive symptoms. However, secondary analyses revealed that change in cardiorespiratory fitness was positively correlated with change in memory performance and bilateral hippocampal volume. Conclusions Aerobic exercise in early AD is associated with benefits in functional ability. Exercise-related gains in cardiorespiratory fitness were associated with improved memory performance and reduced hippocampal atrophy, suggesting cardiorespiratory fitness gains may be important in driving brain benefits.

    Kinesiology taping (KT) is a rehabilitative technique performed by the cutaneous application of a special elastic tape. We tested the safety and efficacy of KT in reducing postoperative chest pain after lung lobectomy. One-hundred and seventeen consecutive patients, both genders, age 18-85, undergoing lobectomy for lung cancer between January 2013 and July 2015 were initially considered. Lobectomies were performed by the same surgical team, with thoracotomy or video-assisted thoracoscopic surgery (VATS) access. Exclusion criteria (n = 25 patients) were: previous KT exposure, recent trauma, pre-existing chest pain, lack of informed consent, >24-h postoperative intensive care unit treatment. After surgery, the 92 eligible patients were randomized to KT experimental group (n = 46) or placebo control group (n = 46). Standard postoperative analgesia was administered in both groups (paracetamol/non-steroidal anti-inflammatory drugs, epidural analgesia including opioids), with supplemental analgesia boluses at patient request. On postoperative day 1 in addition, in experimental group patients a specialized physiotherapist applied KT, with standardized tape length, tension and shape, over three defined skin areas: at the chest access site pain trigger point; over the ipsilateral deltoid/trapezius; lower anterior chest. In control group, usual dressing tape mimicking KT was applied over the same areas, as placebo. Thoracic pain severity score [visual analogue scale (VAS) ranging 0-10] was self-assessed by all patients on postoperative days 1, 2, 5, 8, 9 and 30. The KT group and the control group had similar demographics, lung cancer clinico-pathological features and thoracotomy/VATS ratio. Postoperatively, the two groups also resulted similar in supplemental analgesia, complication rate, mean duration of chest drainage and length of stay. There were no adverse events with KT application. After tape application, KT patients reported overall less thoracic pain than the

    Objective: We sought to determine any benefits of applying a transitional care model in the continuum of cancer pain management, especially after patients' discharge from the hospital. Methods: A total of 156 eligible participants were recruited and randomly assigned into intervention or control groups. The control group received standard care, while the intervention group received extra, specialized transitional care of pain management. Outcomes were measured at weeks 0 and 2e4 and included demographic data, the Brief Pain Inventory, Global Quality of Life Scale, and Satisfaction Degree of Nursing Service. Adequacy of analgesia and severity of pain were assessed with the Pain Management Index and interview findings. Results: After 2e4 weeks of intervention, there was a significant difference in the change in average pain score between intervention and control groups (P <0.05). Reductions in pain scores were significantly greater in the intervention group than in the control group (difference:0.98, P<0.05). Regarding pain management outcomes, there was a significantly better condition in the intervention group compared with the control group;in the intervention group, 79%of patients had adequate opioids, whereas in the control group, only 63% of patients reported having adequate opioids. Furthermore, there was a signif-icant difference between the two groups in quality of life (QOL) scores (P<0.05);the intervention group had significantly higher quality of life than the control group (difference: 1.06). Finally, there was a significant difference in the degree of satisfaction with the home nursing service;the intervention group had a significantly higher degree of satisfaction with the home nursing service in three aspects:quality, content, and attitude of service. Conclusions: The application of a transitional care model in cancer pain management after discharge could help patients to improve their cancer pain management knowledge and analgesics compliance.

    The authors studied cerebral hemodynamics in alcohol dependence and evaluated their changes with application of high-frequency rTMS. A prospective, single-blind, randomized, parallel-group, sham-controlled clinical study was conducted with patients with alcohol dependence (DSM-IV-TR). The study population comprised 25 subjects each in active rTMS, sham rTMS, and healthy control groups. At baseline, cerebral hemodynamic indices were measured with transcranial Doppler sonography. Subjects in the active rTMS group received 10 sessions of rTMS daily; the sham group was administered sham rTMS with the same parameters. Cerebral hemodynamic parameters were repeated 5 minutes after the last rTMS session. At baseline, mean velocity (MV) of both middle cerebral artery (MCA; R-MCA: p=0.003; L-MCA: p=0.002) and anterior cerebral artery (ACA; R-ACA: p=0.003; L-ACA: p=.001) was significantly reduced. Pulsatility index (PI) of MCA (prTMS group, except L-MCA PI, significant differences were observed in values of MV, PI, and RI of both MCA and ACA following rTMS intervention; such changes were not evident in the sham rTMS group. The changes in mean difference in MV of L-MCA (p=0.006) and L-ACA (p=0.015) were statistically significant in the active rTMS group, in comparison with the sham group. Significant differences were also observed between the two groups postintervention, in RI of L-MCA (p=0.001) and ACA (R-ACA: p=0.010; L-ACA: p=0.015). Alcohol dependence may result in altered cerebral hemodynamic parameters, which can be improved with high-frequency rTMS application.

    The first-aid training necessary for obtaining a drivers license in Austria has a regulated and predefined curriculum but has been targeted for the implementation of a new course structure with less theoretical input, repetitive training in cardiopulmonary resuscitation (CPR) and structured presentations using innovative media. The standard and a new course design were compared with a prospective, participant- and observer-blinded, cluster-randomized controlled study. Six months after the initial training, we evaluated the confidence of the 66 participants in their skills, CPR effectiveness parameters and correctness of their actions. The median self-confidence was significantly higher in the interventional group [IG, visual analogue scale (VAS:"0" not-confident at all,"100" highly confident):57] than in the control group (CG, VAS:41). The mean chest compression rate in the IG (98/min) was closer to the recommended 100 bpm than in the CG (110/min). The time to the first chest compression (IG:25s, CG:36s) and time to first defibrillator shock (IG:86s, CG:92s) were significantly shorter in the IG. Furthermore, the IG participants were safer in their handling of the defibrillator and started with countermeasures against developing shock more often. The management of an unconscious person and of heavy bleeding did not show a difference between the two groups even after shortening the lecture time. Motivation and self-confidence as well as skill retention after six months were shown to be dependent on the teaching methods and the time for practical training. Courses may be reorganized and content rescheduled, even within predefined curricula, to improve course outcomes. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available : OBJECTIVE: Controlled hypotension is commonly used to achieve a bloodless operative field which is needed for successful FESS. This study was carried out to assess the hypotensive effect of dexmedetomidine (DEX during FESS. METHODS: Fifty ASA grades I and II patients of either sex aged 20–50 years undergoing FESS were randomly divided into two groups of 25 each. Group D received 10–15 min prior to induction of anesthesia 1 μg/kg IV bolus DEX diluted in 10 ml of normal saline over 10 min. Immediately thereafter an infusion of 0.4 μg/kg/hr of DEX commenced. Group C received placebo bolus and infusion of saline at a rate similar to DEX in Group D. Standard anesthetic technique was used. The surgical field was assessed using Average Category Scale and average blood loss was calculated. Hemodynamic variables (MAP and HR; emergence time and total recovery from anesthesia (Aldrete score ≥9 were recorded. RESULT: Group D reached the desired MAP (55-65 mmHg. In group D patients the average MAP was 55.9±5.3 mm of Hg, where as in group C it was 86.2±11.4 mm of Hg. Patients in group D had a better surgical field, and the duration of surgery was significantly reduced(78.34±16.7mins in group D vs 103.2±113.1 mins in group C The mean awakening time was significantly reduced in patients of Group D (9.1±2.7 mins in group D vs12.8±2.2 mins in group C when compared to patients of Group C. CONCLUSION: This study demonstrated that dexmedetomidine is a safe agent for controlled hypotension and is effective in providing ideal surgical field during FESS.

    Full Text Available Abstract The aim of this study was to assess the effectiveness of low intensity laser therapy in patients with Burning Mouth Syndrome (BMS. Thirty BMS subjects were randomized into two groups – Laser (LG and Placebo (CG. Seven patients dropped out, leaving 13 patients in LG and 10 patients in CG. Each patient received 4 irradiations (laser or placebo twice a week, for two consecutive weeks (blinded to the type of irradiation received. Infrared laser (AsGaAI irradiations were applied to the affected mucosa in scanning mode, wavelength of 790 nm, output power of 20 mW and fluence of 6 J/cm2. A visual analogue scale (VAS was used to assess the therapeutic effect before and after each irradiation, and at all the control time periods: 7, 14, 30, 60 and 90 days after the last irradiation. One researcher delivered irradiation and another recorded the results. Both researchers were blinded, the first to the results, and the second to the type of radiation applied. The results were categorized according to the percentage of symptom level variation, and showed a statistically better response in LG in only two categories of the control checkpoints (p=0.02; Fisher’s Exact Test. According to the protocol used in this study, low intensity laser therapy is as beneficial to patients with BMS as placebo treatment, indicating a great emotional component of involvement in BMS symptomatology. Nevertheless, there were positive results in some statistical analyses, thus encouraging further research in BMS laser therapy with other irradiation parameters.

    The Internet of Things (IoT) allows collecting vast amounts of health-relevant data such as daily activity, body weight (BW), and blood pressure (BP) automatically. The use of IoT devices to monitor diabetic patients has been studied, but could not evaluate IoT-dependent effects because health data were not measured in control groups. This multicenter, open-label, randomized, parallel group study will compare the impact of intensive health guidance using IoT and conventional medical guidance on glucose control. It will be conducted in outpatients with type 2 diabetes for a period of 6 months. IoT devices to measure amount of daily activity, BW, and BP will be provided to IoT group patients. Healthcare professionals (HCPs) will provide appropriate feedback according to the data. Non-IoT control, patients will be given measurement devices that do not have a feedback function. The primary outcome is glycated hemoglobin at 6 months. The study has already enrolled 101 patients, 50 in the IoT group and 51 in the non-IoT group, at the two participating outpatient clinics. The baseline characteristics of two groups did not differ, except for triglycerides. This will be the first randomized, controlled study to evaluate IoT-dependent effects of intensive feedback from HCPs. The results will validate a new method of health-data collection and provision of feedback suitable for diabetes support with increased effectiveness and low cost.

    Background Though moxibustion is frequently used to treat primary dysmenorrhea in China, relevant evidence supporting its effectiveness is still scanty. Methods This study was a pragmatic randomized, conventional drug controlled, open-labeled clinical trial. After initial screen, 152 eligible participants were averagely randomized to receive two different treatment strategies: Moxibustion and conventional drugs. Participants and practitioners were not blinded in this study. The duration of each treatment was 3 months. The primary outcome was pain relief measured by the Visual Analogue Scale. The menstrual pain severity was recorded in a menstrual pain diary. Results 152 eligible patients were included but only 133 of them eventually completed the whole treatment course. The results showed that the menstrual pain intensity in experimental group and control group was reduced from 6.38±1.28 and 6.41±1.29, respectively, at baseline, to 2.54±1.41 and 2.47±1.29 after treatment. The pain reduction was not significantly different between these two groups (P = 0.76), however; the pain intensity was significantly reduced relative to baseline for each group (P<0.01). Three months after treatment, the effectiveness of moxibustion sustained and started to be superior to the drug’s effect (-0.87, 95%CI -1.32 to -0.42, P<0.01). Secondary outcome analyses showed that moxibustion was as effective as drugs in alleviating menstrual pain-related symptoms. The serum levels of pain mediators, such as PGF2α, OT, vWF, β-EP, PGE2, were significantly improved after treatment in both groups (P<0.05). No adverse events were reported in this trial. Conclusions Both moxibustion and conventional drug showed desirable merits in managing menstrual pain, given their treatment effects and economic costs. This study as a pragmatic trial only demonstrates the effectiveness, not the efficacy, of moxibustion for menstrual pain. It can’t rule out the effect of psychological factors during

    Background Placebo treatment can significantly influence subjective symptoms. However, it is widely believed that response to placebo requires concealment or deception. We tested whether open-label placebo (non-deceptive and non-concealed administration) is superior to a no-treatment control with matched patient-provider interactions in the treatment of irritable bowel syndrome (IBS). Methods Two-group, randomized, controlled three week trial (August 2009-April 2010) conducted at a single academic center, involving 80 primarily female (70%) patients, mean age 47±18 with IBS diagnosed by Rome III criteria and with a score ≥150 on the IBS Symptom Severity Scale (IBS-SSS). Patients were randomized to either open-label placebo pills presented as “placebo pills made of an inert substance, like sugar pills, that have been shown in clinical studies to produce significant improvement in IBS symptoms through mind-body self-healing processes” or no-treatment controls with the same quality of interaction with providers. The primary outcome was IBS Global Improvement Scale (IBS-GIS). Secondary measures were IBS Symptom Severity Scale (IBS-SSS), IBS Adequate Relief (IBS-AR) and IBS Quality of Life (IBS-QoL). Findings Open-label placebo produced significantly higher mean (±SD) global improvement scores (IBS-GIS) at both 11-day midpoint (5.2±1.0 vs. 4.0±1.1, p<.001) and at 21-day endpoint (5.0±1.5 vs. 3.9±1.3, p = .002). Significant results were also observed at both time points for reduced symptom severity (IBS-SSS, p = .008 and p = .03) and adequate relief (IBS-AR, p = .02 and p = .03); and a trend favoring open-label placebo was observed for quality of life (IBS-QoL) at the 21-day endpoint (p = .08). Conclusion Placebos administered without deception may be an effective treatment for IBS. Further research is warranted in IBS, and perhaps other conditions, to elucidate whether physicians can benefit patients using placebos consistent with

    The aim of this study was to investigate the effect of Reiki on pain, anxiety, and hemodynamic parameters on postoperative days 1 and 2 in patients who had undergone cesarean delivery. The design of this study was a randomized, controlled clinical trial. The study took place between February and July 2011 in the Obstetrical Unit at Odemis Public Hospital in Izmir, Turkey. Ninety patients equalized by age and number of births were randomly assigned to either a Reiki group or a control group (a rest without treatment). Treatment applied to both groups in the first 24 and 48 hours after delivery for a total of 30 minutes to 10 identified regions of the body for 3 minutes each. Reiki was applied for 2 days once a day (in the first 24 and 48 hours) within 4-8 hours of the administration of standard analgesic, which was administered intravenously by a nurse. A visual analog scale and the State Anxiety Inventory were used to measure pain and anxiety. Hemodynamic parameters, including blood pressure (systolic and diastolic), pulse and breathing rates, and analgesic requirements also were recorded. Statistically significant differences in pain intensity (p = .000), anxiety value (p = .000), and breathing rate (p = .000) measured over time were found between the two groups. There was a statistically significant difference between the two groups in the time (p = .000) and number (p = .000) of analgesics needed after Reiki application and a rest without treatment. Results showed that Reiki application reduced the intensity of pain, the value of anxiety, and the breathing rate, as well as the need for and number of analgesics. However, it did not affect blood pressure or pulse rate. Reiki application as a nursing intervention is recommended as a pain and anxiety-relieving method in women after cesarean delivery.

    Full Text Available Background: Insulin receptor substrate (IRS Type 1 is a main substrate for the insulin receptor, controls insulin signaling in skeletal muscle, adipose tissue, and the vascular, so it is an important candidate gene for insulin resistance (IR. We aimed to compare the effects of the Dietary Approaches to Stop Hypertension (DASH and Usual Dietary Advices (UDA on IRS1 gene expression in women at risk for cardiovascular disease. Materials and Methods: A randomized controlled clinical trial was performed in 44 women at risk for cardiovascular disease. Participants were randomly assigned to a UDA diet or the DASH diet. The DASH diet was rich in fruits, vegetables, whole grains, and low-fat dairy products and low in saturated fat, total fat, cholesterol, refined grains, and sweets, with a total of 2400 mg/day sodium. The UDA diet was a regular diet with healthy dietary advice. Gene expression was assessed by the real-time polymerase chain reaction at the first of study and after 12 weeks. Independent sample t-test and paired-samples t-test were used to compare means of all variables within and between two groups respectively. Results: IRS1 gene expression was increased in DASH group compared with UDA diet (P = 0.00. Weight and waist circumference decreased in DASH group significantly compared to the UDA group (P < 0.05 but the results between the two groups showed no significant difference. Conclusion: DASH diet increased IRS1 gene expression and probably has beneficial effects on IR risks.

    Full Text Available Background Restless leg syndrome (RLS is a common problem in patients with chronic renal failure. It can reduce the quality of life and sleep disturbances. This disorder is usually treated pharmacologically. Recently, complementary medicine methods have been suggested because of chemical drugs adverse effects. There is not enough evidence about the effect of aromatherapy on RLS. Objectives The aim of this study was to determine the effects of massage with lavender oil on RLS symptoms in hemodialysis patients. Patients and Methods This randomized clinical trial study included 70 hemodialysis patients with RLS that were randomly assigned into two groups in 2014. The experimental group received effleurage massage using lavender oil and control group received routine care for three weeks. Data was collected with RLS questionnaire and analyzed using independent and paired t-test and Chi-square test. Results The mean RLS scores were not significantly different in the two groups at the start of study (22.41 ± 7.67 vs. 22.90 ± 4.38, P = 0.76. At the end of study, the mean RLS score significantly decreased in the intervention group, while this score remained relatively un-changed in the control group (12.41 ± 5.49 vs. 23.23 ± 4.52, P < 0.0001. Conclusions Lavender oil massage was effective to improve RLS in hemodialysis patients. It has no adverse effects, is practical and cost-effective. It is suggested to be used along with routine treatment of RLS in hemodialysis patients.

    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

    Heel prick is a frequent painful procedure in newborns. A lancet or a 26-gauge needle is used for a heel prick in India. To compare the pain caused by heel prick with a lancet or a 26-gauge needle in newborns admitted in the neonatal intensive care unit (NICU) using the preterm infant pain profile (PIPP). This randomized controlled trial was conducted over 2 months in a Level III NICU with a sample size of 40 subjects (20 in each group), which was required for the study to have a power of 80% with an alpha error of 0.05. Hemodynamically stable newborns on at least those on partial oral feeds undergoing heel prick for routine glucose monitoring were randomized into two groups within 48 h of NICU admission after informed parental consent: heel prick with a lancet or with a 26-gauge needle using computer-generated random numbers. Two milliliters of expressed breast milk was given 2 min before the heel prick. Pain before, during and after (1 and 5 min) was assessed using the PIPP score. The primary outcome measure was the PIPP score. The secondary outcome measures were the duration of audible cry and the number of pricks needed for an adequate sample. Statistical analysis was done using the Mann Whitney U test and Friedman's test on SPSS v.21. A p value of < 0.05 was significant. There were 40 neonates, 24 males and 16 females included in the study with a median age of 7 days. The mean birth weight was 2441 g (SD: 699) at a mean gestation of 34.4 weeks (SD: 3.2). The median PIPP scores at 0-30 s after heel prick were 7.05 ± 3.57 with a lancet vs. 9.35 ± 3.68 a needle (p = 0.052). There was a significantly lower duration of audible cry with use of lancet (10.5 ± 18.5 s vs. 75.2 ± 12.0 s with needle; p = 0.03). All heel pricks resulted in adequate sampling. Heel prick with a lancet causes less crying than a 26-gauge needle, though the PIPP scores are not significantly different. © The Author [2017]. Published by Oxford

    This randomized controlled study aims to determine the effect of pilates mat exercises on dynamic and static balance, hamstring flexibility, abdominal muscle activity and endurance in healthy adults. Female healthy volunteer university students randomly assigned into two groups. Group 1 followed a pilates program for an hour two times a week. Group 2 continued daily activities as control group. Dynamic and static balance were evaluated by Sport Kinesthetic Ability Trainer (KAT) 4000 device. Hamstring flexibility and abdominal endurance were determined by sit-and-reach test, curl-up test respectively. Pressure biofeedback unit (PBU) was used to measure transversus abdominis and lumbar muscle activity. The physical activity of the participants was followed by International Physical Activity Questionnaire-Short Form. Twenty-three subjects in pilates group and 24 control subjects completed the study. In pilates group, statistical significant improvements were observed in curl-up, sit-and-reach test, PBU scores at sixth week (Ppilates group for sit-and-reach test (P=0.01) and PBU scores (Ppilates training program has been found to have beneficial effect on static balance, flexibility, abdominal muscle endurance, abdominal and lumbar muscle activity. These parameters have no effect on balance.

    Full Text Available Introduction: Medication nonadherence is highly prevalent in patients with bipolar disorders and often results in worsening disease prognosis. The purpose of this study was to investigate the effect of group psychoeducation on medication adherence in female patients with bipolar mood disorder type I. Methods: This randomized controlled trial was conducted on 76 patients with bipolar mood disorder admitted in female psychiatric wards of Razi teaching hospital, Tabriz, Iran. The participants were selected by convenience sampling method and were randomly assigned to experimental and control groups. Patients in experimental group received 10 continuous 90 minutes sessions of psychoeducation, two times a week. Medication adherence was measured using the medicine check list and medication adherence rating scale (MARS before and after intervention. Data analysis was performed with SPSS ver.13. Results: There was no significant difference between two groups regarding medication adherence before the intervention. After the study intervention, the mean scores of medication adherence check list and medication adherence rating scale in the experimental group were significantly higher than the control group. Conclusion: Since group psychoeducation was effective in improving patients' medication adherence, it could be recommended for psychiatric nurses to apply this intervention in the clinical setting.

    Annona muricata leaf infusion has traditionally been consumed to maintain health, but is now considered for use in treating cancer patients. The objective of this study was to elucidate the effects of A. muricata leaf extract in humans and human cell lines. Thirty outpatients with colorectal cancer who had undergone primary tumor resection were enrolled in a randomized double-blind placebo- controlled pre-post-trial. They were divided into two groups: those who ingested A. muricata leaf extract (n=14) and those who ingested a placebo (n=14) daily for 8 weeks. Twenty-eight subjects completed the trial; they were equally distributed between the two groups. Serum from patients of both groups was compared for cytotoxicity against colorectal cancer cell lines. The nutritional status of patients was monitored throughout the study. Ex vivo and clinical studies showed higher cytotoxicity in the supplemented group compared with the placebo group. Further research is required to investigate the long-term effect of A.muricata leaf extract, particularly on parameters directly related to cytotoxic activity toward colorectal cancer cells and nutrition status.

    In this paper, we investigate the bichromatic coherent random lasing actions from the dye-doped polymer stabilized blue phase liquid crystals. Two groups of lasing peaks, of which the full widith at half maximum is about 0.3 nm, are clearly observed. The shorter- and longer-wavelength modes are associated with the excitation of the single laser dye (DCM) monomers and dimers respectively. The experimental results show that the competition between the two groups of the lasing peaks can be controlled by varying the polarization of the pump light. When the polarization of the pump light is rotated from 0° to 90°, the intensity of the shorter-wavelength lasing peak group reduces while the intensity of the longer-wavelength lasing peak group increases. In addition, a red shift of the longer-wavelength modes is also observed and the physical mechanisms behind the red-shift phenomenon are discussed.

    Asthma care plans typically include complicated written instructions. Customized, audio-recorded instructions may bridge health literacy gaps and improve treatment plan understanding. To measure the effects of a recordable greeting card-style tool (Talking Card) on asthma control and parental care of children with asthma. Multisite randomized trial in two primary care clinics, including children 4-11 years old with uncontrolled asthma and their parents. Parent-child dyads were randomized to usual care of asthma or usual care plus the Talking Card. Dyads completed three asthma-focused visits over 3 months. At the visit, card recipients received customized instructions recorded by the pediatrician onto an audio chip in the card. Asthma control was measured by using the Childhood Asthma Control Test. Card use and parental satisfaction were measured by parental survey (card arm only). Outcomes were analyzed by using generalized estimating equations and frequency distributions. Sixty-four dyads participated and attended 166 clinic visits. Card use was associated with a 1.6-point increase in Childhood Asthma Control Test score (p = 0.02) and a clinic visit regardless of card use with a three-point increase (p asthma. The Talking Card, a novel audio communication tool, was associated with improved asthma control and deemed highly desirable by parents and children struggling to control asthma. This inexpensive portable tool may be useful in other chronic disorders and in locales with low literacy and poor access to digital technology.

Secondly, we proceed with a log......  We consider health care data from a cluster-randomized intervention study in primary care to test whether the average health care costs among study patients differ between the two groups. The problems of analysing cost data are that most data are severely skewed. Median instead of mean...... is commonly used for skewed distributions. For health care data, however, we need to recover the total cost in a given patient population. Thus, we focus, on making inferences on population means. Furthermore, a problem of clustered data is added as data related to patients in primary care are organized...

    The evidence of suicide prevention training for nurses is scarce. Strategies to enhance general nurses' ability in suicide risk assessment are critical to develop effective training programs in general medical settings. This study was aimed to examine the effectiveness of an interactive discussion group in a suicide prevention training program for general nurses. In this randomized study with two groups of pre-post study design, the sample was recruited from the Medical, Surgical, and Emergency/Intensive Care Sectors of a 2000-bed general hospital via stratified randomization. Among the 111 nurses, 57 participants randomly assigned to the control group received a two-hour baseline suicide gatekeeper lecture, and 54 participants assigning to the experimental group received an additional five-hour group discussion about suicide risk assessment skills. Using a case vignette, the nurses discussed and assessed suicide risk factors specified in a 10-item Chinese SAD PERSONS Scale during a group discussion intervention. The findings revealed that the nurses achieved significant and consistent improvements of risk identification and assessment after the intervention without influencing their mental health status for assessing suicide risks. The result suggested an effective approach of interactive group discussion for facilitating critical thinking and learning suicide risk assessment skills among general nurses.

    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.

    Objective:To evaluate the efficacy of tranexamic acid in reduction of blood loss during and after cesarean section.Methods:Women included in the current double blinded, randomized, controlled trial were recruited from women attending for elective cesarean section and randomized into two groups; study group: received tranexamic acid with induction of anesthesia plus10IU of oxytocin injection after delivery of the baby.Control group: received only oxytocin 10IU injection after delivery of the baby.Results:Twenty four hours post-operative hemoglobin level was significantly higher in study group(11.2±1.5 mg/dL) compared to control(9.6±1.2 mg/dL), also24 hours post-operative hematocrit was significantly higher in study group(30.2±6.6) compared to control(29.2±2.8).Calculated total blood loss from placental delivery till end of cesarean section was significantly less in study group compared to control(369.5±198.0 versus606.8±193.0 mL; respectively), also, calculated vaginal bleeding during first6 hours post-operative was significantly less in study group compared to control(85.0±30.7 mL versus130.8±49.3 mL, respectively).The incidence of post-partum hemorrhage was significantly less in study group compared to control(31.1% versus63.2%; respectively), also the need for iron replacement therapy was significantly less frequent in study group compared to control(0.9% versus6.6%, respectively). Conclusions:Tranexamic acid can be used safely to reduce blood loss during cesarean section. Reduced blood loss after tranexamic acid was associated with improvement of post-operative hemoglobin, hematocrit and with reduction of post-partum need for iron replacement.

    Full Text Available The existing reviews of massage therapy (MT research are either limited to infants, adults, or were conducted prior to the publication of the most recent studies using pediatric samples. Randomized controlled trials (RCTs of pediatric MT are reviewed. A literature search yielded 24 RCTs of pediatric MT, defined as the manual manipulation of soft tissue intended to promote health and well-being in recipients between 2 and 19 years of age. Because RCTs of pediatric MT varied considerably in the amount and types of data reported, quantitative and narrative review methods were both used. Single-dose and multiple-dose effects were examined separately. Among single-dose effects, significant reductions of state anxiety were observed at the first session (g = 0.59, P < 0.05 and the last session (g = 1.10, P < 0.01 of a course of treatment. Effects for salivary cortisol (g = 0.28, negative mood (g = 0.52 and behavior (g = 0.37 were non-significant. Three of eleven multiple-dose effects were statistically significant. These were trait anxiety (g = 0.94, P < 0.05, muscle tone (g = 0.90, P < 0.01 and arthritis pain (g = 1.33, P < 0.01. Results of studies not permitting effect size calculation were judged to be generally consistent with quantitative results. MT benefits pediatric recipients, though not as universally as sometimes reported. Numerous weaknesses endemic to MT research (e.g. low statistical power, frequent failure to report basic descriptive statistics are identified, and recommendations for future pediatric MT research are discussed.

    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 Background: The evidence stemming from trials on restorative materials is shaped not only by trial findings, but also trial design and validity. We aimed to evaluate both aspects in randomized controlled dental restorative trials published from 2005–2015. Methods: Using systematic review methodology, we retrieved trials comparing restorative or adhesive dental materials. Two authors independently assessed design, risk of bias, registration status, and findings of trials. Descriptive and regression analyses were performed. Results: 114 studies on 15,321 restorations placed mainly in permanent teeth of 5232 patients were included. Per trial, the median number of patients was 37 (25th/75th percentiles: 30/51. Follow-up was 24 (20/48 months. Seventeen percent of trials reported on sample size calculations, 2% had been registered. Most trials (90% used US Public Health Service (USPHS criteria, and had a high risk of bias. More recent trials were more likely to have been registered, to have reported on sample size calculations, to be of low risk of bias, and to use other than USPHS-criteria. Twenty-three percent of trials yielded significant differences between groups. The likelihood of such differences was significantly increased in older studies, studies with potential reporting bias, published in journals with high impact factor (>2, longer follow-up periods, and not using USPHS-criteria. Conclusions: The majority of dental restorative trials published from 2005–2015 had limited validity. Risk of bias decreased in more recent trials. Future trials should aim for high validity, be registered, and use defined and appropriate sample sizes, follow-up periods, and outcome measures.

    Exercise training reduces adiposity and risk of cardiovascular disease. However, the combined effects of habitual free-living physical activity and aerobic training on waist circumference, weight, fitness, and blood pressure in postmenopausal women are unknown. To evaluate the effects of habitual physical activity levels during aerobic training on weight, waist circumference, fitness, and blood pressure. Secondary analysis of an RCT. Original data collected April 2001 to June 2005 and analyzed in 2012. Postmenopausal women in a supervised exercise trial. Women (n=325) were randomized to 4, 8, or 12 kcal/kg per week of aerobic training or a control group for 6 months. All outcome measures were collected at baseline and follow-up. Changes in dependent variables within each training group were evaluated across tertiles of pedometer-determined habitual physical activity outside exercise training sessions. Changes in waist circumference and weight. Reductions in waist circumference were significantly greater with higher steps/day accumulated outside exercise training compared to lower levels in the 4 (high: -4.8 cm vs low: -1.4 cm, p=0.03); 8 (high: -4.2 cm vs low: -0.4 cm, p=0.03), and 12 kcal/kg per week groups (high: -4.1 cm vs low: -0.7 cm, p=0.05). For all groups, p-trend≤0.03. A trend was observed for greater weight reduction with higher steps/day in the 4 kcal/kg per week group (p-trend=0.04) but not for the other exercise doses. No effects were observed for blood pressure or fitness measures (all p>0.05). In postmenopausal women, higher habitual physical activity while participating in aerobic training was associated with greater reductions in central adiposity, and was supportive of weight loss compared to lower levels.

    Sample size calculations are advocated by the Consolidated Standards of Reporting Trials (CONSORT) group to justify sample sizes in randomized controlled trials (RCTs). This study aimed to analyse the reporting of sample size calculations in trials published as RCTs in orthodontic speciality journals. The performance of sample size calculations was assessed and calculations verified where possible. Related aspects, including number of authors; parallel, split-mouth, or other design; single- or multi-centre study; region of publication; type of data analysis (intention-to-treat or per-protocol basis); and number of participants recruited and lost to follow-up, were considered. Of 139 RCTs identified, complete sample size calculations were reported in 41 studies (29.5 per cent). Parallel designs were typically adopted (n = 113; 81 per cent), with 80 per cent (n = 111) involving two arms and 16 per cent having three arms. Data analysis was conducted on an intention-to-treat (ITT) basis in a small minority of studies (n = 18; 13 per cent). According to the calculations presented, overall, a median of 46 participants were required to demonstrate sufficient power to highlight meaningful differences (typically at a power of 80 per cent). The median number of participants recruited was 60, with a median of 4 participants being lost to follow-up. Our finding indicates good agreement between projected numbers required and those verified (median discrepancy: 5.3 per cent), although only a minority of trials (29.5 per cent) could be examined. Although sample size calculations are often reported in trials published as RCTs in orthodontic speciality journals, presentation is suboptimal and in need of significant improvement.

    To determine the short-term and long-term effects of dichlorphenamide (DCP) on attack frequency and quality of life in hyperkalemic (HYP) and hypokalemic (HOP) periodic paralysis. Two multicenter randomized, double-blind, placebo-controlled trials lasted 9 weeks (Class I evidence), followed by a 1-year extension phase in which all participants received DCP. Forty-four HOP and 21 HYP participants participated. The primary outcome variable was the average number of attacks per week over the final 8 weeks of the double-blind phase. The median attack rate was lower in HOP participants on DCP than in participants on placebo (0.3 vs 2.4, p = 0.02). The 9-week mean change in the Physical Component Summary score of the Short Form-36 was also better in HOP participants receiving DCP (treatment effect = 7.29 points, 95% confidence interval 2.26 to 12.32, p = 0.006). The median attack rate was also lower in HYP participants on DCP (0.9 vs 4.8) than in participants on placebo, but the difference in median attack rate was not significant (p = 0.10). There were no significant effects of DCP on muscle strength or muscle mass in either trial. The most common adverse events in both trials were paresthesia (47% DCP vs 14% placebo, both trials combined) and confusion (19% DCP vs 7% placebo, both trials combined). DCP is effective in reducing the attack frequency, is safe, and improves quality of life in HOP periodic paralysis. These studies provide Class I evidence that DCP significantly reduces attack frequency in HOP but lacked the precision to support either efficacy or lack of efficacy of DCP in HYP. © 2016 American Academy of Neurology.

    The use of random jet arrays, already employed in water tank facilities to generate zero-mean-flow homogeneous turbulence, is extended to air as a working fluid. A novel facility is introduced that uses two facing arrays of individually controlled jets (256 in total) to force steady homogeneous turbulence with negligible mean flow, shear, and strain. Quasi-synthetic jet pumps are created by expanding pressurized air through small straight nozzles and are actuated by fast-response low-voltage solenoid valves. Velocity fields, two-point correlations, energy spectra, and second-order structure functions are obtained from 2D PIV and are used to characterize the turbulence from the integral-to-the Kolmogorov scales. Several metrics are defined to quantify how well zero-mean-flow homogeneous turbulence is approximated for a wide range of forcing and geometric parameters. With increasing jet firing time duration, both the velocity fluctuations and the integral length scales are augmented and therefore the Reynolds number is increased. We reach a Taylor-microscale Reynolds number of 470, a large-scale Reynolds number of 74,000, and an integral-to-Kolmogorov length scale ratio of 680. The volume of the present homogeneous turbulence, the largest reported to date in a zero-mean-flow facility, is much larger than the integral length scale, allowing for the natural development of the energy cascade. The turbulence is found to be anisotropic irrespective of the distance between the jet arrays. Fine grids placed in front of the jets are effective at modulating the turbulence, reducing both velocity fluctuations and integral scales. Varying the jet-to-jet spacing within each array has no effect on the integral length scale, suggesting that this is dictated by the length scale of the jets.

    Full Text Available Relevance: Plantar fasciitis, the most common cause of heel pain, is due to repetitive strain injury to the medial arch and the heel, causing functional disabilities. Any biomechanical alteration in the lower extremity has its effect on plantar fascia. Kaltenborn mobilization techniques have been proved effective in improving the range of motion of the affected joints. There is a need to evaluate these techniques in plantar fasciitis by treating whole lower extremity. Participants: 20 subjects with the mean age (23.80±2.71 with primary heel pain are recruited in the study. Method: Subjects of randomized controlled trial were randomly allocated into two groups, Group A (n=10 received therapeutic ultrasound, stretching’s and exercises and Group B ( n=10 received therapeutic ultra sound, Kaltenborn mobilizations to the affected joints of lower extremity, stretching and exercises. The outcome measures are visual analogue scale ( VAS , foot function index ( FFI and range of motion measured by Goniometer assessed on day 1 pre-treatment and day 12 post treatment. Analysis: It was done using Mann Whitney U test and Wilcoxon matched pairs test using SPSS software. Results: The intra-group mean differences in pre and post values for group-A are 1.80±2.39, 2.50±2.64, 3.40±1.84, and 19.75±8.16 for ankle dorsiflexion, plantarflexion, VAS and FFI respectively, and in group-B are 1.00±2.11, 10.50±8.32, 4.70±0.67and 28.07±8.26 for ankle dorsiflexion, plantarflexion, VAS and FFI respectively. The intra-group comparison had shown statistical significance with p<0.05 and whereas in between comparison group-B had shown better improvement than group-A. Conclusion: Kaltenborn mobilizations along with therapeutic ultrasound, stretches and exercises have shown better improvement compared to the control group.

    Lifestyle and behaviour change are important factors in the prevention of cardiovascular disease and reduction of premature mortality. Public health initiatives have focused on opportunities for healthcare staff to deliver lifestyle advice routinely in primary and secondary care but there is no consistent approach to onward referrals and the rate of uptake of advice remains low. We do not know if advice is more effective in supporting behaviour change when a systematic approach is taken that includes identification of barriers to change, directing patients toward services, referral to services, and feedback on outcome. This is a single-centre, randomized, unblinded feasibility trial in an acute hospital setting which aims to assess the feasibility of a definitive trial and provide proof of concept for the systematic delivery of individualized lifestyle advice in patients managed through an acute cardiology in-patient service.Patients will be recruited before discharge and randomized to two groups. A control group will receive the usual lifestyle assessment and referral, while an intervention group will receive the usual assessment plus the new individualized lifestyle assessment and referral. The new assessment will inform assignment of each patient to one of three categories based on personal barriers to change. Patients may be referred to a formal lifestyle-change programme, through the 'Leeds Let's Change' website, or they may be guided in self-management, using goal setting, or they may be assigned to a 'deferment' category, for reassessment at follow-up. These latter patients will be given a contact card for the 'Leeds Let's Change' service. Lifestyle change is an important mechanism for improving health and wellbeing across the population but there are widely acknowledged difficulties in addressing lifestyle factors with patients and supporting behaviour change. A systematic approach to assessment would facilitate audit and provide an indicator of the quality

    Introduction Massage is a time-honored method by which women have received comfort throughout the millennia, yet it has not been rigorously evaluated in the modern day delivery suite. No study to date that we are aware of has evaluated the effect of massage therapy by a regulated massage therapist on labor pain. The purpose of this study was to evaluate the effectiveness of massage therapy provided by registered massage therapists in managing pain among women in active labor. Methods BC Women’s Hospital, Vancouver, BC. Research Design: a randomized controlled trial. Participants: 77 healthy nulliparous women presenting in spontaneous labor. Intervention: Swedish massage administered for up to five hours by a registered massage therapist during labor vs. standard care. Main outcome measures include: cervical dilation at the time of administration of epidural, compared using estimated marginal means in an analysis of covariance. We also compared perception of pain at three time periods during labor according to cervical dilation at 3–4 cm, 5–7 cm, and 8–10 cm using the McGill Present Pain Intensity Scale. Results The mean cervical dilation at the time of epidural insertion after adjustment for station of the presenting part, cervical dilation, and status of membranes on admission to hospital was 5.9 cm (95% CI 5.2–6.7) compared to 4.9 in the control group (95% CI 4.2–5.8). Scores on the McGill Pain Scale were consistently lower in the massage therapy group (13.3 vs. 16.9 at 3–4 cm, 13.3 vs. 15.8 at 5–6 cm, and 19.4 vs. 28.3 at 7–8 cm), although these differences were not statistically significant. Conclusions Our findings from this pilot study suggest that massage therapy by a registered massage therapist has the potential to be an effective means of pain management that may be associated with delayed use of epidural analgesia. It may therefore have the potential to reduce exposure to epidural analgesia during labor and decrease rates of associated

  17. Active Video Game Exercise Training Improves the Clinical Control of Asthma in Children: Randomized Controlled Trial.

    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.

    The purpose of this study was to investigate the effects of brain-computer interface (BCI)-controlled functional electrical stimulation (FES) training on shoulder subluxation of patients with stroke. Twenty subjects were randomly divided into two groups: the BCI-FES group (n = 10) and the FES group (n = 10). Patients in the BCI-FES group were administered conventional therapy with the BCI-FES on the shoulder subluxation area of the paretic upper extremity, five times per week during 6 weeks, while the FES group received conventional therapy with FES only. All patients were assessed for shoulder subluxation (vertical distance, VD; horizontal distance, HD), pain (visual analogue scale, VAS) and the Manual Function Test (MFT) at the time of recruitment to the study and after 6 weeks of the intervention. The BCI-FES group demonstrated significant improvements in VD, HD, VAS and MFT after the intervention period, while the FES group demonstrated significant improvements in HD, VAS and MFT. There were also significant differences in the VD and two items (shoulder flexion and abduction) of the MFT between the two groups. The results of this study suggest that BCI-FES training may be effective in improving shoulder subluxation of patients with stroke by facilitating motor recovery.

    2016-01-01

    Full Text Available Background Tonsillectomy is associated with early and late postoperative complications in the children. Previous studies have shown some effects of dexamethasone; however, there has been a lack of studies that evaluate its effects on other complications, including odynophagia and otalgia. Objectives We aimed to investigate the effects of dexamethasone on odynophagia and otalgia after surgery. Patients and Methods In this randomized clinical trial, 100 patients who underwent adenotonsillectomy were divided into two groups: one group received 0.1 mg/kg of dexamethasone (case and the other received Ringer serum as a placebo (control. Intravenous (IV dexamethasone was prescribed to be administered by a nurse on the ward. The incidence of bleeding, nausea and vomiting, odynophagia, voice change, acetaminophen intake, halitosis and otalgia, and activity were evaluated at 24 h and during the first 7 days after surgery. Results The mean ages of patients were 7.1 ± 2.8 and 6.5 ± 2.4 years in the control and case groups, respectively. The overall proportions of females and males were 41% and 59%, respectively. No significant difference in demographic data was seen between the two groups (P > 0.05. There was a significant difference in terms of odynophagia and nausea and vomiting between the case and control groups after 24 h (P = 0.001. There was no significant difference between the case and control groups in terms of bleeding, voice change, halitosis, or nausea and vomiting after 7 days (P > 0.05. Meanwhile, there were a significant difference in the incidence of acetaminophen intake (60% vs. 30%, P = 0.002, odynophagia (24% vs. 6%, P = 0.011, otalgia (20% vs. 4%, P = 0.014, and activity (80% vs. 98%, P = 0.004 of patients after 7 days between the groups. Conclusions In children undergoing adenotonsillectomy, dexamethasone has a significant antiemetic effect and decreases odynophagia, otalgia, and the need for analgesia.

    The effects of balneotherapy were evaluated in patients with osteoarthritis of the hip. This randomized, controlled, investigator-blinded study enrolled outpatients with hip osteoarthritis according to ACR criteria. In addition to home exercise therapy, one patient group received balneotherapy for 3 weeks on 15 occasions. The mineral water used in this study is one of the mineral waters with the highest sulfide ion content (13.2 mg/L) in Hungary. The control group received exercise therapy alone. The WOMAC Likert 3.1 index and the EQ-5D quality of life self-administered questionnaire were completed three times during the study: prior to first treatment, at the end of the 3-week treatment course, and 12 weeks later. The main endpoint was achievement of Minimal Clinically Important Improvement (MCII) at 12 weeks, defined as ≥7.9 points in a normalized WOMAC function score. The intention to treat analysis included 20 controls and 21 balneotherapy patients. At 12 weeks, 17 (81 %) balneotherapy group patients had Minimal Clinically Important Improvement and 6 (30 %) of controls ( p = 0.001). Comparing the results of the two groups at the end of treatment, there was a significant difference in the WOMAC stiffness score only, whereas after 12 weeks, the WOMAC pain, stiffness, function, and total scores also showed a significant difference in favor of the balneotherapy group. The difference between the two groups was significant after 12 weeks in point of EQVAS score, too. The results of our study suggest that the combination of balneotherapy and exercise therapy achieves more sustained improvement of joint function and decreases in pain than exercise therapy alone.

    Medical Education can be delivered in the traditional classroom or via novel technology including an online classroom. To test the hypothesis that learning in an online classroom would result in similar outcomes as learning in the traditional classroom when using a flipped classroom pedagogy. Randomized controlled trial. A total of 274 subjects enrolled in a Neuro-otology training program for non-Neuro-otologists of 25 h held over a 3-day period.

    To evaluate in a twelve-month, randomized placebo-controlled study whether pure administration of phytoestrogen genistein (54 mg/day) might reduce cytogenetic biomarkers in peripheral lymphocytes of postmenopausal women. A total of 57 postmenopausal women met the criteria and were randomly assigned to receive phytoestrogen genistein (n = 30) or placebo (n = 27). There was no significant difference in age, length of time since menopause or body mass index between the two groups. After one year, plasma genistein level was 0.14 +/- 0.01 micromol/L in the control group and 0.72 +/- 0.08 micromol/L in the genistein group (P < 0.0001). At baseline, sister chromatid exchange rate was 4.97 +/- 2.17 in the control group and 4.96 +/- 1.83 in the genistein group (P = 0.89). After one year, sister chromatid exchange rate was 4.96 +/- 2.16 in the control group and 3.98 +/- 1.14 in the genistein group (P < 0.05). High frequency cells count was 3% in the genistein group and 5% in the control group (P < 0.05) at the end of the study. Chromosomal aberration frequency was 5.55% in the control group at time 0 and 5.75% in the genistein group; after one year, the figures were 5.86% in the control group and 4.5% in the genistein group (P < 0.05). After one year, there was a negative relationship between sister chromatid exchange rate and plasma levels (r = - 0.43; P < 0.05) in the genistein group. Phytoestrogen genistein has been shown in postmenopausal women to be effective in the reduction of cytogenetic biomarkers. The protective effect on genomic damage appears to be a particularly promising tool in reducing the risk of cancer.

    Full Text Available Although there is evidence of the benefits of propolis on human health, the vast majority of studies have been conducted using animal models. The present study includes the chemical characterization and clinical evaluation of the effects of the oral administration of propolis solution on the oxidative status and modulation of lipids in a human population in Talca, Chile. Chemical characterization of propolis, total phenol, flavonoids, and total antioxidant capacity were determined by ORAC. Identification of phenols and flavonoids in propolis was assessed by HPLC-DAD. A double-blind, placebo-controlled clinical trial was conducted. Subjects provided informed consent form and the Bioethics Committee of the Universidad de Talca approved protocol. Eligible subjects (n=67 were randomized in two groups: propolis (n=35 and placebo (n=32. All subjects were evaluated at 0 (baseline, 45, and 90 days. In the propolis group, we observed that increases in HDL-c went from 53.9 ± 11.9 to 65.8 ± 16.7 mg/dL (p<0.001 from baseline to 90 days. Compared to placebo subjects, consumption of propolis induced a net increase in GSH levels (p<0.0001 and a decrease (p<0.001 in TBARS levels for the propolis group. Our findings indicate potential benefits of propolis use in human health. The use of propolis appears to have positive effects on oxidative status and improvement of HDL-c, both of which contribute to a reduced risk of cardiovascular disease.

    Full Text Available Background: Traditionally propofol has been used for providing sedation in dilatation and curettage (D and C. Recently, dexmedetomidine has been tried, but very little evidence exists to support its use. Aims: The aim was to compare hemodynamic and recovery profile of both the drugs along with a degree of comfort experienced by patients and the usefulness of the drug to surgeons. Settings and Design: Tertiary care center and open-label randomized controlled trial. Materials and Methods: Patients posted for D and C were enrolled in two groups (25 each. Both groups received fentanyl 1 μg/kg intravenous (IV at the beginning of the procedure. Group P received IV propofol in dose of 1.5 mg/kg over 10-15 min and Group D received dexmedetomidine at a loading dose of 1 μg/kg over 10 min, followed by 0.5 μg/kg/h infusion until Ramsay sedation score reached 3-4. Hemodynamic vitals were compared during and after the procedure. In the recovery room time to reach modified Aldrete score (MAS of 9-10 and patient′s and surgeon′s satisfaction scores were also recorded and compared. Results: In Group D, patients had statistically significant lower heart rate at 2, 5, 10 and 15 min as compared to Group P. Hypotension was present in 52% in Group P and 4% in Group D (P < 0.05. MAS of 9-10 was achieved in 4.4 min in subjects in Group D in contrast to 16.2 min in Group P (P < 0.05. Group D showed higher patient and surgeon satisfaction scores (P < 0.05. Conclusion: Dexmedetomidine provide better hemodynamic and recovery profile than propofol. It can be a superior alternative for short surgical day care procedures.

    Full Text Available Background: Hyperbaric ropivacaine produce more reliable sensory and motor block, with faster onset, better quality of muscles relaxation than isobaric ropivacaine. So, this study was designed to compare the efficacy of hyperbaric ropivacaine with isobaric ropivacaine in patients undergoing lower abdominal surgery. Methods: A randomized controlled double blind study in two groups of patients. group A (n=35 received 3 ml of isobaric ropivacaine 6 mg/ml (18 mg. Group B (n=35 received 3 ml of hyperbaric ropivacaine 6 mg/ml (18 mg. The onset and duration of sensory block at dermatome level T10, maximum upper and lower spread of sensory block, intensity, and duration of motor block were recorded. Statistical Analysis: Block characteristics were compared using the two-tailed Mann - Whitney U-test. The proportion of side effects was compared using the Chi-square test. Results: The median time of onset of sensory block at the T10 dermatome was 4.4±1.3 min in group B and 6.0±1.03 min in group A. The median time to maximum block height was 16.7±3.7 min in group A and 12.03±1.96 min in group B. The median duration of complete motor recovery (B0 was significantly shorter in the heavy ropivacaine group (166.5±11.7 min compared with the isobaric ropivacaine group (192.9±9.6 min. Conclusions: Intrathecal hyperbaric ropivacaine provides more rapid, adequate, and good quality of sensory and motor block with rapid post-operative recovery as compare to isobaric ropivacaine.

    Full Text Available Background: Traditionally, conservative treatment of thoracolumbar (TL burst fractures without neurologic deficit has encompassed the application of an extension brace. However, their effectiveness on maintaining the alignment, preventing posttraumatic deformities, and improving back pain, disability and quality of life is doubtful. Objective: The objective was to identify and summarize the evidence from randomized controlled trials (RCTs to determine whether bracing patients who suffer TL fractures adds benefices to the conservative manage without bracing. Materials and Methods: Seven databases were searched for relevant RCTs that compared the clinical and radiological outcomes of orthosis versus no-orthosis for TL burst fractures managed conservatively. Primary outcomes were: (1 Loss of kyphotic angle; (2 failure of conservative management requiring subsequent surgery; and (3 disability and pain outcomes. Secondary outcomes were defined by health-related quality of life and in-hospital stay. Results: Based on predefined inclusion criteria, only two eligible high-quality RCTs with a total of 119 patients were included. No significant difference was identified between the two groups regarding loss of kyphotic angle, pain outcome, or in-hospital stay. The pooled data showed higher scores in physical and mental domains of the Short-Form Health Survey 36 in the group treated without orthosis. Conclusion and Recommendation: The current evidence suggests that orthosis could not be necessary when TL burst fractures without neurologic deficit are treated conservatively. However, due to limitations related with number and size of the included studies, more RCTs with high quality are desirable for making recommendations with more certainty.

    Full Text Available Abstract Background To evaluate the effect of a dietary supplement containing polyunsaturated fatty acids, in association with Humulus lupulus extract, on the quality of sleep using the Leeds sleep evaluation questionnaire (LSEQ in subjects with moderate to severe sleep disorders. Methods Randomized placebo-controlled trial, in a Population-based setting. Participants were adult patients 25 to 65 years old with a chronic primary insomnia who volunteered for the study. The tested intervention consisted of two soft gelatine capsules per day, containing either the dietary supplement (active group or olive oil (placebo group for a month. Subjects could also volunteer for two ancillary studies on melatonin and actigraphy. Evaluation criteria included i perception of the quality of sleep at the end of treatment using the LSEQ questionnaire, ii sleep efficiency measured by one-week actigraphic movement measurement performed before and during the treatment in a subsample of subjects, iii night melatonin and 6 sulfatoxymelatonin (aMT6S urine rates in a subsample of subjects. Results The average of Leeds score was similar in both groups (p = 0.95. A marked improvement in the quality of sleep was observed in both placebo (62% and active (65% group (p = 0.52. The evolution of urinary melatonin, aMT6S, and of the Mel/aMT6S ratio showed no differences between the two groups. Sleep efficiency, as measured by actigraphy, improved similarly in both groups during the treatment period, from 72% to 76% and 75% in the active and placebo group respectively (p = 0.91. Conclusions The dietary supplement had neither effect on the perceived quality of sleep, nor on the melatonin metabolism and sleep-wake cycle. Trial registration: clinical trials.gov:NCT00484497

    Full Text Available BACKGROUND: Although livestock vaccination is effective in preventing Rift Valley fever (RVF epidemics, there are concerns about safety and effectiveness of the only commercially available RVF Smithburn vaccine. We conducted a randomized controlled field trial to evaluate the immunogenicity and safety of the new RVF Clone 13 vaccine, recently registered in South Africa. METHODS: In a blinded randomized controlled field trial, 404 animals (85 cattle, 168 sheep, and 151 goats in three farms in Kenya were divided into three groups. Group A included males and non-pregnant females that were randomized and assigned to two groups; one vaccinated with RVF Clone 13 and the other given placebo. Groups B included animals in 1st half of pregnancy, and group C animals in 2nd half of pregnancy, which were also randomized and either vaccinated and given placebo. Animals were monitored for one year and virus antibodies titers assessed on days 14, 28, 56, 183 and 365. RESULTS: In vaccinated goats (N = 72, 72% developed anti-RVF virus IgM antibodies and 97% neutralizing IgG antibodies. In vaccinated sheep (N = 77, 84% developed IgM and 91% neutralizing IgG antibodies. Vaccinated cattle (N = 42 did not develop IgM antibodies but 67% developed neutralizing IgG antibodies. At day 14 post-vaccination, the odds of being seropositive for IgG in the vaccine group was 3.6 (95% CI, 1.5 - 9.2 in cattle, 90.0 (95% CI, 25.1 - 579.2 in goats, and 40.0 (95% CI, 16.5 - 110.5 in sheep. Abortion was observed in one vaccinated goat but histopathologic analysis did not indicate RVF virus infection. There was no evidence of teratogenicity in vaccinated or placebo animals. CONCLUSIONS: The results suggest RVF Clone 13 vaccine is safe to use and has high (>90% immunogenicity in sheep and goats but moderate (> 65% immunogenicity in cattle.

    This double-blind, randomized controlled study was conducted with the aim to investigate the effect of magnetic field therapy applied to the hip region on clinical and functional status in ankylosing spondylitis (AS) patients. Patients with AS (n = 66) who were diagnosed according to modified New York criteria were enrolled in this study. Patients were randomly divided in two groups. Participants were randomly assigned to receive magnetic field therapy (2 Hz) (n = 35), or placebo magnetic field therapy (n = 31) each hip region for 20 min. Patients in each group were given heat pack and short-wave treatments applied to bilateral hip regions. Both groups had articular range of motion and stretching exercises and strengthening exercises for surrounding muscles for the hip region as well as breathing and postural exercises by the same physical therapist. These treatment protocols were continued for a total of 15 sessions (1 session per day), and patients were examined by the same physician at months 1, 3 and 6. Visual analogue scale (VAS) pain, VAS fatigue, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Metrologic Index (BASMI), DFI, Harris hip assessment index and Ankylosing Spondylitis Quality of Life scale (ASQOL) were obtained at the beginning of therapy and at month 1, month 3 and month 6 for each patient. There were no significant differences between groups in the VAS pain, VAS fatigue, morning stiffness, BASDAI, BASFI, BASMI, DFI, Harris hip assessment index and ASQoL at baseline, month 1, month 3 or month 6 (p > 0.05). Further randomized, double-blind controlled studies are needed in order to establish the evidence level for the efficacy of modalities with known analgesic and anti-inflammatory action such as magnetotherapy, particularly in rheumatic disorders associated with chronic pain.

    Full Text Available This paper presents a new method for single phase variable voltage inverter based on Random Pulse Width Modulation. In Random Pulse Width Modulation based inverter, the frequency spectrum of the output current and voltage waveforms becomes continuous because of the randomization of the switching function of the devices controlling the output voltages. This paper establishes a theory that if the distributions of the random numbers generated by the random source are kept within certain limit with respect to the peak value of reference sinusoidal waveform, the frequency spectrum can be controlled. On the basis of the results, a novel drive using variable tap changing transformer (optional and adaptive random number generator, to control the ratio between the numbers generated by the random source and the reference waveform has been suggested that will guarantee a better power quality profile for a broad range of output voltages.

    Full Text Available Background: Diabetes causes the increased concentration of circulatory cytokines as a result of inflammation. Considering that pomegranate juice (PJ is known to have antioxidant and anti-inflammatory properties, the purpose of this study was to determine the effects of PJ consumption on markers of inflammation in patients with type 2 diabetes (T2D. Materials and Methods: In a randomized, double-blind clinical trial study, 50 patients with T2D (40-65 years old were randomly assigned to one of two groups. Participants in each group received either 250 mL/day PJ or a control beverage for 12 weeks. Biochemical markers including fasting plasma glucose (FPG, insulin and inflammatory markers were assayed on the baseline and follow-up blood samples. Results: In all, 44 patients in two groups were included in the analysis: PJ (n = 22 and placebo (n = 22. After 12 weeks of intervention, in the PJ group, there were 32% and 30% significant decreases in plasma C-reactive protein (hs-CRP and Interlukin-6, respectively (P < 0.05. The mean ± SD plasma interlukin-6 (7.1 ± 5.6 vs. 11.9 ± 14.4 mg/L and hs-CRP (1791 ± 1657 and 1953 ± 1561 ng/mL concentrations in the PJ group were significantly lower than the placebo group after intervention (P < 0.05. Conclusion: PJ consumption by patients with T2D does not affect FPG or the insulin resistance index (HOMA-IR, whereas it does reduce Interlukin-6 and hs-CRP concentrations in plasma. Therefore, PJ consumption may have an anti-inflammatory effect in patients with T2D.

    Introduction. The aim of this study was to assess the vascular benefits of dark chocolate in healthy and young individuals. Methods. A randomized and controlled trial was carried out involving 60 healthy volunteers, randomized into two groups: control group (CG; n = 30) and intervention group (IG; n = 30). The IG ingested a daily dosage of 10 g of dark chocolate (>75% cocoa) for a month. Blood pressure (BP), flow-mediated dilation (FMD), arterial stiffness index (ASI), aortic pulse wave velocity (PWV), and pulse wave analysis (PWA) were assessed at baseline and one week after the one-month intervention period. Results. Arterial function improved after intervention in the IG, with PWV decreasing from 6.13 ± 0.41 m/s to 5.83 ± 0.53 m/s (P = 0.02), with no significant differences observed in the CG. A significant decrease in ASI (0.16 ± 0.01 to 0.13 ± 0.01; P 75% cocoa) during a month significantly improves vascular function in young and healthy individuals. PMID:24982813

    Air way intubation for general anesthesia usually leads to sore throat after surgery. Ketamine plays an important role to block a number of receptors related to pain. Benzydamine hydrochloride is a non-steroidal anti-inflammatory drug that has been used to improve oropharyngeal disorders. In this study, it was intended to compare the effect of gargling different solutions before the surgery on post-operative sore throat (POST) in patients who underwent general anesthesia for hysterectomy. A total of 60 patients who underwent the elective hysterectomy were entered to the randomized controlled trial regarding to the eligibility criteria. Patients were simply randomly allocated to three groups and received one code. Every code was representative for a specific drug: 20 cc normal saline (control group) or 1.5 mg benzydamine in 20 cc solution or 20 mg ketamine in 20 cc solutions. All the research teams were blinded to the received solutions. POST was evaluated with numerical rating scale. The data were entered to SPSS software and analysis of variance (ANOVA) and Kruskal-Wallis one-way analysis of variance test, were performed. The mean ages of ketamine, benzydamine, and normal saline recipients were not significantly different. The trend of the severity of sore throat during the first 24 h after the operation in ketamine recipients was significantly lower than the other two groups (P ketamine and benzydamine, but the ketamine effect was more noticeable.

    Full Text Available Objectives: Compare the effectiveness of PapacarieTM gel for the chemo-mechanical removal of carious lesions on primary teeth to conventional caries removal with a low-speed bur with regard to execution time, clinical aspects and radiographic findings. Material and Methods: A randomized controlled clinical trial with a split-mouth design was carried out. The sample was composed of 20 children aged four to seven years, in whom 40 deciduous teeth were randomly divided into two groups: chemo-mechanical caries removal with PapacarieTM and removal of carious dentin with a low-speed bur. Each child underwent both procedures and served as his/her own control. Restorations were performed with glass ionomer cement. The time required to perform the procedure was also analyzed. The patients underwent longitudinal clinical and radiographic follow-up of the restorations. Results: No statistically significant difference between groups was found regarding the time required to perform the procedures and the radiographic follow up. Statistically significant differences between groups were found in the clinical evaluation at 6 and 18 months after treatment. Conclusion: PapacarieTM is as effective as the traditional method for the removal of carious dentin on deciduous teeth, but offers the advantages of the preservation of sound dental tissue as well as the avoidance of sharp rotary instruments and local anesthesia.

    Research supports a link between exercise and falls prevention in the older population. Our aims were to evaluate pain perception and balance skills in a group of elderly subjects and to examine the consequences of a standardized equipment-free exercise program intervention on these variables. The study utilized a randomized controlled trial method. 92 subjects were recruited from a rural Sicilian village (Resuttano, Sicily, Italy). Subjects were randomly split into two groups, an experimental group (EG; n = 49) and a control group (CG; n = 43). Qualified fitness instructors delivered the standardized physical exercise program for the EG whilst the CG did not receive this exercise intervention. The Berg Balance Scale and the Oswestry Disability Index were administered in both groups before (T0) and after the intervention (T1). At T1, the EG group significantly improvement in balance (p balance and perception of pain in the elderly. This type of intervention can consequently provide a low cost strategy to counteract the rate of disability in elderly.

    Different and new approaches have been proposed to prevent the risk of falling of elderly people, particularly women. This study investigates the possibility that a new protocol based on the focal mechanical muscle vibration may reduce the risk of falling of elderly women. A pragmatic randomized controlled triple-blind trial with a 6-month follow-up after intervention randomized 350 women (mean age 73.4 years + 3.11), members of local senior citizen centers in Rome, into two groups: vibrated group (VG) and control group (CG). For VG participants a mechanical vibration (lasting 10 min) was focally applied on voluntary contracted quadriceps muscles, three times a day during three consecutive days. CG subjects received a placebo vibratory stimulation. Subjects were tested immediately before (T0) and 30 (T1) and 180 (T2) days after the intervention with the Performance-Oriented Mobility Assessment (POMA) test. All subjects were asked not to change their lifestyle during the study. CG underwent sham vibratory treatment. While CG did not show any statistically significant change of POMA at T1 and T2, VG revealed significant differences. At T2, ≈47% of the subjects who completed the study obtained the full score on the POMA test and ≈59% reached the full POMA score. The new protocol seems to be promising in reducing the risk of falling of elderly subjects.

    This study tested the efficacy of an 8-week culturally targeted nutrition and physical activity intervention on body composition. A randomized, attention-controlled, two-group trial was conducted in a blackowned commercial gym with a sample of 366 predominantly healthy, obese African American women. A free 1-year membership to the study site gym was provided to participants in both groups. Data were collected at baseline, 2, 6, and 12 months. Sample retention at 1 year was 71%. Between-group longitudinal analysis including only participants with complete data revealed a trend toward weight stability in the intervention group at 2 months compared with controls (+0.05 kg/m(2), p = 0.75; +0.32 kg/m(2), p = 0.08, respectively), disappearing at 12 months (+1.37 kg/m(2), p = 0.0001; +1.02 kg/m(2), p = 0.001, respectively). Within-group analysis demonstrated that intervention and control participants' fitness (1-mile run-walk) improved by 1.9 minutes (p = 0.0001) and 2.3 minutes (p = 0.0001), respectively, at 12 months. Mixed model regression analyses demonstrated a significant main effect of the intervention on fitness (p = 0.0185) and a marginally significant effect on body mass index (BMI) (p = 0.057), at 2 months, disappearing by 6 months. By 12 months, however, the controls exhibited a significant advantage in waist circumference stability compared with intervention participants (+1.1 cm, p = 0.2763; +2.1 cm, p = 0.0002, respectively). The intervention produced modest short-term improvements in body composition, but the economic incentive of a free 1-year gym membership provided to all participants was a more potent intervention than the education and social support intervention tested. However, longer-term fitness enhancement remains elusive and demands research and policy attention. These findings have policy implications in that employer-/insurer-subsidized gym memberships may require interventions targeting other levels of change (e.g., physical or social

    Background Echinacea is widely used to treat common cold. Objective To assess potential benefits of echinacea as common cold treatment. Design Randomized controlled trial with four parallel groups: 1) no pills, 2) placebo pills (blinded), 3) echinacea pills (blinded), or 4) echinacea pills (open-label). (NCT00065715) Setting Community-based trial. Participants People aged 12 to 80 years with new onset common cold. Interventions Extracts of Echinacea purpurea and E. angustifolia root were used to make tablets standardized to alkamide content. Indistinguishable placebo tablets contained only inert ingredients. Measurements The primary outcome was area-under-the-curve global severity, with severity assessed twice daily by self report on the Wisconsin Upper Respiratory Symptom Survey (WURSS-21). Secondary outcomes included interleukin-8 and neutrophil count from nasal wash assessed at intake and two days later. Results Of 719 enrolled, 713 completed the protocol. Participants were 64% female and 88% white, with mean age 33.7 years. Mean global severity was 236 and 258 for blinded and unblinded echinacea, 264 for blinded placebo, and 286 for those without pills. Contrasting the two blinded groups yields a 28 point (95% CI = −69 to 13) trend toward benefit for echinacea (p=0.089). Mean illness duration for the blinded and unblinded echinacea groups was 6.34 and 6.76 days, respectively, compared to 6.87 days for blinded placebo and 7.03 for no pills. Contrasting blinded groups yields a 0.53 day (95% CI = −1.25 to 0.19) trend toward benefit (p = 0.075). Median change interleukin-8 (pg/mL) and neutrophil cell count were: no pills (30, 1), blinded placebo (39, 1), blinded echinacea (58, 2), and open-label echinacea (70, 1), also not statistically significant. Limitations Higher-than-expected variability limited power to detect small-but-potentially-important benefits. Conclusions The observed shorter illness duration and lower severity seen in the echinacea groups were

    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

    We consider the general problem of analysis and design of control systems in the presence of uncertainties. We treat uncertainties that affect a control system as random variables. The performance of the system is measured by the expectation of some derived random variables, which are typically bounded. We develop adaptive sequential randomized algorithms for estimating and optimizing the expectation of such bounded random variables with guaranteed accuracy and confidence level. These algorithms can be applied to overcome the conservatism and computational complexity in the analysis and design of controllers to be used in uncertain environments. We develop methods for investigating the optimality and computational complexity of such algorithms.

  4. Digital building blocks for controlling random waves based on supersymmetry

    2016-01-01

    Harnessing multimode waves allows high information capacity through modal expansions. Although passive multimode devices including waveguides, couplers, and multiplexers have been demonstrated for broadband responses in momentum or frequency domains, collective switching of multimodes remains a challenge, due to the difficulty in imposing consistent dynamics on all eigenmodes. Here we overcome this limitation by realizing digital switching of spatially random waves, based on supersymmetric pairs of multimode potentials. We reveal that supersymmetric transformations of any parity-symmetric potential derive the parity reversal of all eigenmodes, which allows the complete isolation of random waves at the 'off' state. Building blocks for binary and many-valued logics are then demonstrated for random waves: a harmonic pair for binary switching of arbitrary wavefronts and a P\\"oschl-Teller pair for multi-level switching which implements the fuzzy membership function.

    Full Text Available Abstract Background Gyejibongnyeong-hwan (GJBNH is one of the most popular Korean medicine formulas for menstrual pain of dysmenorrhea. The concept of blood stagnation in Korean medicine is considered the main factor of causing abdominal pain, or cramps, during menstrual periods. To treat the symptoms, GJBNH is used to fluidify the stagnated blood and induce the blood flow to be smooth, reducing pain as the result. The purpose of this trial is to identify the efficacy of GJBNH in dysmenorrhea caused by blood stagnation. Methods This study is a multi-centre, randomised, double-blind, controlled trial with two parallel arms: the group taking GJBNH and the group taking placebo. 100 patients (women from age 18 to 35 will be enrolled to the trial. Through randomization 50 patients will be in experiment arm, and the other 50 patients will be in control arm. At the second visit (baseline, all participants who were already screened that they fulfil both the inclusion and the exclusion criteria will be randomised into two groups. Each group will take the intervention three times per day during two menstrual cycles. After the treatment for two cycles, each patient will be followed up during their 3rd, 4th and 5th menstrual cycles. From the screening (Visit 1 through the second follow-up (Visit 6 the entire process will take 25 weeks. Discussion This trial will provide evidence for the effectiveness of GJBNH in treating periodical pain due to dysmenorrhea that is caused by blood stagnation. The primary outcome between the two groups will be measured by changes in the Visual Analogue Score (VAS of pain. The secondary outcome will be measured by the Blood Stagnation Scale, the Short-form McGill questionnaire and the COX menstrual symptom scale. Analysis of covariance (ANCOVA and repeated measured ANOVA will be used to analyze the data analysis. Trial registration Current Controlled Trials: ISRCTN30426947

    2012-08-01

    Full Text Available Objectives: Transcranial direct current stimulation (tDCS has demonstrated some efficacy in treatment-resistant major depression (TRD. The majority of previous controlled studies have used anodal stimulation to the left dorsolateral prefrontal cortex (DLPFC and a control location such as the supraorbital region on for the cathode. Several open label studies have suggested effectiveness from anodal stimulation to the left DLPFC combined with cathodal stimulation to the right DLPFC. Thus, this study evaluated the efficacy of tDCS using anodal stimulation to the left DLPFC and cathodal stimulation to the right DLPFC compared to sham tDCS. Methods: Subjects between the ages of 18 and 65 were recruited from a tertiary care university hospital. Twenty-four subjects with TRD and a 17-item Hamilton Depression Rating Scale (HDRS greater than 21 were randomized to receive tDCS or sham tDCS. The rates of remission were compared between the two treatment groups.Results: The remission rates did not differ significantly between the two groups using an intention to treat analysis. More subjects in the active tDCS group had failed a course of electroconvulsive therapy in the current depressive episode. Side effects did not differ between the two groups and in general the treatment was very well tolerated. Conclusion: Anodal stimulation to the left DLPFC and cathodal stimulation to the right DLPFC was not efficacious in TRD. However, a number of methodological limitations warrant caution in generalizing from this study. Ongoing, controlled studies should provide further clarification on the efficacy of this stimulation configuration in TRD.

    The present study was carried out to examine this hypothesis that administration of selenium can prevent the development of injuries by brain trauma and thus can modulate patients' functional recovery and also improve posttraumatic outcome. This double-blinded controlled trial was carried out on 113 patients who were hospitalized following traumatic brain injury (TBI) with Glasgow Coma Scale score of 4-12 that were randomly assigned to receive selenium within 8 h after injury plus standard treatment group or routine standard treatment alone as the control. The primary endpoint was to assess patients' functional recovery at 2 months after the injury based on extended Glasgow Outcome Scale score (GOS-E). Secondary outcomes included the changes in Full Outline of Unresponsiveness score (FOUR) score, Sequential Organ Failure Assessment (SOFA) score, and acute physiology and chronic health evaluation (APACHE) III score, side effects of selenium, length of Intensive Care Unit (ICU) stay, and length of hospital stay. There was no difference in the length of ICU and hospital stay, the trend of the change in FOUR and SOFA scores within 15 days of first interventions, and the mean APACHE III score on the 1(st) and 15(th) days between the two groups. Mortality was 15.8% in selenium group and 19.6% in control group with no between-group difference. No difference was revealed between the two groups in appropriate outcome according to GOS-E score at 60 ± 10 days and also 30 ± 5 days according to the severity of TBI. This human trial study could not demonstrate beneficial effects of intravenous infusion of selenium in the improvement of outcomes in patients with acute TBI.

    The objective of this study was to compare glycemic control and insulin dosage in children with type 1 diabetes treated by a modified intensified insulin therapy MII using insulin pens (and premixed and regular insulin) with those on conventional insulin therapy. This was a longitudinal, randomized controlled trial for 6 months or more. From a cohort of 125 children with previously diagnosed type-1 diabetes (more than a year after diagnosis) two groups were randomly selected Group AI (n=20) and Group B (n=20). Group AI children and 10 children with recently diagnosed type 1 diabetes (Group AII) were allocated to MII using regular insulin and premixed insulin (30/70 and 40/60 and 50/50). Group B patients continued their conventional insulin therapy for the whole period of the trial. The main outcome measures were glycemic control measured by mean blood glucose concentration and percentage of glycated haemoglobin and total daily insulin dose. Mean blood glucose concentrations before the three main meals, and at midnight, (148, 147, 179 and 127 mg/dl, respectively) were lower in children receiving intensified MII compared with those receiving conventional insulin therapy (192, 174, 194 and 179 mg/dl, respectively) (standardized mean difference 34+/-15 mg/dl), equivalent to a difference of 1.9+/-0.8 mmol/l. This improved control during MII was achieved with no change in the average daily insulin dose in group-AI. In group-AII insulin dose decreased significantly during their first 6 moths of treatment (honeymooning). Glycemic control is better during MII using insulin pens and premixed and regular insulin compared with conventional insulin therapy, without any significant change in insulin dose needed to achieve this level of control. The difference in glycemic control between the two methods is significant and could reduce the risk of micro-vascular complications.

    Full Text Available The random time-varying delays would reduce control performance and even deteriorate the EV system. To deal with random time-varying delays and achieve a real-time steady-state response, considering randomness of delay and a rapid response, an H∞-based delay-tolerant linear quadratic regulator (LQR control method based on Taylor series expansion is proposed in this paper. The results of cosimulations with Simulink and CarSim demonstrate the effectiveness of the proposed controller through the control performance of yaw rate, sideslip angle, and the running track. Moreover, the results of comparison with the other controller illustrate the strength of explicitly.

    Full Text Available Background: Cesarean delivery is the most common surgical procedure and this prevalence is on the rise. Given these trends, cesarean wound complications, such as disruption or infection, remain an important cause of post-cesarean morbidity. Methods: We conducted a single-center randomized controlled trial that included women with viable pregnancies (≥24 weeks undergoing cesarean delivery at Motahary University Hospital, Urmia, Iran from April to November 2014. All cesarean types were included: scheduled or unscheduled and primary or repeat cesareans. Women were excluded for the following reasons: inability to obtain informed consent, immune compromising disease (e.g. AIDS, chronic steroid use, diabetic mellitus and BMI≥30. Of 266 women, 133 were randomized to staples and 133 women to suture group. Results: The mean±SD age of the staples group was 27.6±5.4 years and mean±SD age of suture was 28.7±5.9 years. Multiparity is the most frequent in both groups that by using Chi-square test, no significant differences were observed between the two groups (P=0.393. The most frequent indication for cesarean section in both groups was history of cesarean section in staple 40 cases (30.1% and suture 32 cases (24.1%. The survey was conducted using the Chi-square test was not significant (P=0.381. Pain at 6 weeks postoperatively was significantly less in the staple group (P=0.001. Operative time was longer with suture closure (4.68±0.67 versus 1.03±0.07 minute, P<0.001. The Vancouver scale score was significantly less in suture closure (6.6±0.8 versus 7.5±0.9, P=0.001. Wound disruption was significantly less in suture closure (3.8% versus 11.3%, P=0.017. Conclusion: The staple group had low pain and operation time but had a significant wound disruption and scar. The patients who have suffered a significant wound disruption were affected by age (P=0.022 and BMI (P=0.001 at compared those who were not affected by factors such as age or high BMI as

    Many studies reveal that neglect is a major cause of disability in stroke patients, and two months from onset neglect is still present in approximately 50% of individuals with a right brain lesion. Among the various methods of neglect rehabilitation, we have turned our attention to the prism adaptation treatment, developed by Rossetti in 1998. This treatment uses prismatic lenses, which produce a deviation of the fixation point of the visual field of 10 degrees to the right, 5 degrees below the coordinates of reference resulting from neglect. To set out the possible effectiveness of less powerful lenses, we studied the response of a group of neglect patients treated with prismatic lenses that produce a deviation of the fixation point of only 5 degrees to the right, comparing them with a group of patients receiving placebo lenses. Randomized controlled trial. Outpatients. The study involved 29 patients with left visual neglect. All patients were assessed with a battery of seven visual-spatial tests. All patients were randomized by the pilot center and assigned to two different groups: "A" treated with pointing exercises and prismatic lenses of 5° to the right; "B" treated with pointing exercises and neutral lenses. Each group was treated with 5 rehabilitation sessions, lasting about 30 minutes each, from Monday to Friday for one week in the morning, by the same investigator, in each center. The results showed that the prismatic lenses of only five degrees, used for the study, did not contribute to the variation in performance. Thus, this deviation of the fixation point of the visual field to the right is not sufficient to create a therapeutic effect. The improvement observed within the two groups, seems likely to be correlated with the pointing exercises, which force the subject to perform a visuomotor task with the healthy arm also in the neglected side. We believe that in order to carry out an effective treatment with prismatic lenses they must have a grade of at

    Full Text Available Abstract Background An aging population poses significant challenges to health care in China. Health management has been implemented to reduce the costs of care, raise health service utilization, increase health knowledge and improve quality of life. Several studies have tried to verify the effectiveness of health management in achieving these goals worldwide. However, there have been insufficient randomized control trials (RCTs to draw reliable conclusions. The few small-scale studies conducted in China include mostly the general population rather than the elderly. Our study is designed to evaluate the impact of community-based health management on the health of the elderly through an RCT in Nanjing, China. Methods Two thousand four hundred participants, aged 60 or older and who gave informed consent, were randomly allocated 1:1 into management and control groups, the randomization schedule was concealed from community health service center staff until allocation. Community-based health management was applied in the former while the latter was only given usual care. After 18 months, three categories of variables (subjective grading health indices, objective health indices and health service utilization were measured based on a questionnaire, clinical monitoring and diagnostic measurements. Differences between the two groups were assessed before and after the intervention and analyzed with t-test, χ2-test, and multiple regression analysis. Results Compared with the control group, the management group demonstrated improvement on the following variables (P Conclusion Community-based health management improved both subjective grading health indices, objective health indices and decreased the number of outpatient clinic visits, demonstrating effectiveness in improving elderly health.

    2008-04-01

    Full Text Available Abstract Background Splinting as part of the overall post-surgical management of patients after release of Dupuytren's contracture has been widely reported, though there is variation in practice and criteria for using it. The evidence on its effectiveness is sparse, of poor quality and contradictory with studies reporting negative and positive effects. Methods/Design A multi-centre, pragmatic, randomized, controlled trial is being conducted to evaluate the effect of static night splinting for six months on hand function, range of movement, patient satisfaction and recurrence at 1 year after fasciectomy or dermofasciectomy. Using a centrally administered computer randomization system consented patients will be allocated to one of two groups: i splint group who will be given a static splint at approximately 10 to 14 days after surgery to be worn for 6 months at night time only as well as hand therapy; ii non-splint group, who will receive hand therapy only. The primary outcome measure is the patient-reported Disabilities of the Arm, Hand and Shoulder Questionnaire (DASH. Secondary outcomes are total active flexion and extension of fingers, patient satisfaction and recurrence of contracture. Outcome measures will be collected prior to surgery, 3 months, 6 months and 1 year after surgery. Using the DASH as the primary outcome measure, where a difference of 15 points is considered to be a clinically important difference a total of 51 patients will be needed in each group for a power of 90%. An intention-to-treat analysis will be used. Discussion This pragmatic randomized controlled trial will provide much needed evidence on the clinical effectiveness of post-operative night splinting in patients who have undergone fasciectomy or dermofasciectomy for Dupuytren's contracture of the hand.

    Full Text Available BACKGROUND: Narcotic drugs are usually used for postoperative pain control which could cause several complications such as respiratory depression and apnea. Therefore, replacement of these drugs with safer analgesics is recommended. The aim of this study was to compare the analgesic effects of suppository diclofenac and pethidine in post-cesarean section (C/S patients. METHODS: In this clinical trial, pregnant women who were admitted to Alzahrah Hospital, Isfahan, Iran, between August and February 2004 and met the inclusion criteria were recruited. After obtaining informed consent, the patients were randomly assigned (block randomization to two groups. In group A, 100 mg rectal suppository diclofenac was used after operation at four time points: at the end of operation and 8, 16 and 24 hours after the operation. Group B received pethidine 1 mg/kg intramuscularly at similar time points. The pain scores were assessed at 2, 10, 18 and 26 hours after C/S using the Visual Analogue Scale (VAS. Age, gestational age, parity, history of previous abortion, C/S and abdominal surgery, level of education, pain score, side effects and satisfaction level were assessed. Analysis was carried out with ANCOVA model and χ2 Mantel Haenszel tests by SPSS.10 software. P<0.05 was considered significant. RESULTS: Two hundred forty patients met inclusion criteria. Age, parity, history of previous abortion, history of previous C/S and abdominal surgery, level of education and satisfaction level were similar in the two groups (P>0.05. There was no significant difference between side effects in the two groups except for dizziness in 11 cases in group B. There were significant statistical difference between pain intensity in 10, 18 and 26 hours after C/S in group A and group B (2.05 ± 2.07, 1.4 ± 1.6 and 0.5 ± 1.1 vs. 2.6 ± 2.2, 2.3 ± 2.2 and 1.3 ± 1.9 respectively. CONCLUSIONS: The results of the present study showed that the use of suppository diclofenac is an

    Age-related cognitive and brain declines can result in functional deterioration in many cognitive domains, dependency, and dementia. A major goal of aging research is to investigate methods that help to maintain brain health, cognition, independent living and wellbeing in older adults. This randomized controlled study investigated the effects of 20 1-h non-action video game training sessions with games selected from a commercially available package (Lumosity) on a series of age-declined cognitive functions and subjective wellbeing. Two groups of healthy older adults participated in the study, the experimental group who received the training and the control group who attended three meetings with the research team along the study. Groups were similar at baseline on demographics, vocabulary, global cognition, and depression status. All participants were assessed individually before and after the intervention, or a similar period of time, using neuropsychological tests and laboratory tasks to investigate possible transfer effects. The results showed significant improvements in the trained group, and no variation in the control group, in processing speed (choice reaction time), attention (reduction of distraction and increase of alertness), immediate and delayed visual recognition memory, as well as a trend to improve in Affection and Assertivity, two dimensions of the Wellbeing Scale. Visuospatial working memory (WM) and executive control (shifting strategy) did not improve. Overall, the current results support the idea that training healthy older adults with non-action video games will enhance some cognitive abilities but not others.

    Background: Childhood obesity is becoming a global problem and its incidence is increasing. The role of dietary intervention with fruits containing vitamin C and flavonoid to control obesity consequences in childhood has not been yet defined. Lemon (Citrus aurantifolia) peels contain flavonoid, pectin and vitamin C. We aimed to compare the effects of lemon peels and placebo on cardiometabolic risk factors and markers of endothelial function among adolescents with overweight and obesity. Methods: In this triple-masked, randomized controlled trial, 60 overweight/obese adolescents were enrolled in a 4-week trial. Eligible participants were randomly assigned into two groups of equal number receiving daily oral capsules containing lemon powder or placebo. Fasting blood sugar, lipid profile, ICAM-1 and VCAM-1, as well as systolic and diastolic blood pressure were compared between the two groups before and after administration of medication and placebo. Results: Of the total 60 enrolled patients, 30 and 29 patients in the lemon and control groups completed the study, respectively. The results of within-group analysis demonstrated a slight reduction in body mass index, LDL-C and systolic blood pressure in the lemon group, but no between group differences existed in the studied variables. Conclusion: This study revealed that consumption of lemon peel extract has some beneficial effects for childhood obesity; however, no considerable effect was documented on anthropometric measures and biochemical factors. Future studies with longer follow up are highly recommended.

    Full Text Available ABSTRACT BACKGROUND: Succinylcholine is commonly used to achieve profound neuromuscular blockade of rapid onset and short duration. OBJECTIVE: The present study compared the efficacy of pregabalin for prevention of succinylcholine-induced fasciculation and myalgia. DESIGN: Prospective, randomized, placebo controlled, double blinded study. MATERIALS AND METHODS: Patients of both genders undergoing elective spine surgery were randomly assigned to two groups. Patients in Group P (pregabalin group received 150 mg of pregabalin orally 1 h prior to induction of anesthesia with sips of water and patients in Group C (control group received placebo. Anesthesia was induced with fentanyl 1.5 mcg/kg, propofol 1.5-2.0 mg/kg followed by succinylcholine 1.5 mg/kg. The intensity of fasciculations was assessed by an observer blinded to the group allotment of the patient on a 4-point scale. A blinded observer recorded postoperative myalgia grade after 24 h of surgery. Patients were provided patient-controlled analgesia with fentanyl for postoperative pain relief. RESULTS: Demographic data of both groups were comparable (p > 0.05. The incidence of muscle fasciculation's was not significant between two groups (p = 0.707, while more patients in group C had moderate to severe fasciculation's compared to group P (p = 0.028. The incidence and severity of myalgia were significantly lower in group P (p < 0.05. CONCLUSION: Pregabalin 150 mg prevents succinylcholine-induced fasciculations and myalgia and also decreases the fentanyl consumption in elective sine surgery.

    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

    Recent studies aimed to evaluate the potential effects of perceptive rehabilitation in Parkinson Disease reporting promising preliminary results for postural balance and pain symptoms. To date, no randomized controlled trial was carried out to compare the effects of perceptive rehabilitation and conventional treatment in patients with Parkinson Disease. To evaluate whether a perceptive rehabilitation treatment could be more effective than a conventional physical therapy program in improving postural control and gait pattern in patients with Parkinson Disease. Single blind, randomized controlled trial. Department of Physical and Rehabilitation Medicine of a University Hospital. Twenty outpatients affected by idiopathic Parkinson Disease at Hoehn and Yahr stage ≤3. Recruited patients were divided into two groups: the first one underwent individual treatment with Surfaces for Perceptive Rehabilitation (Su-Per), consisting of rigid wood surfaces supporting deformable latex cones of various dimensions, and the second one received conventional group physical therapy treatment. Each patient underwent a training program consisting of ten, 45-minute sessions, three days a week for 4 consecutive weeks. Each subject was evaluated before treatment, immediately after treatment and at one month of follow-up, by an optoelectronic stereophotogrammetric system for gait and posture analysis, and by a computerized platform for stabilometric assessment. Kyphosis angle decreased after ten sessions of perceptive rehabilitation, thus showing a substantial difference with respect to the control group. No significant differences were found as for gait parameters (cadence, gait speed and stride length) within Su-Per group and between groups. Parameters of static and dynamic evaluation on stabilometric platform failed to demonstrate any statistically relevant difference both within-groups and between-groups. Perceptive training may help patients affected by Parkinson Disease into restoring

    Background Delirium is a frequent complication after cardiac surgery and its occurrence is associated with poor outcomes. The purpose of this study was to investigate the impact of perioperative dexmedetomidine administration on the incidence of delirium in elderly patients after cardiac surgery. Methods This randomized, double-blinded, and placebo-controlled trial was conducted in two tertiary hospitals in Beijing between December 1, 2014 and July 19, 2015. Eligible patients were randomized into two groups. Dexmedetomidine (DEX) was administered during anesthesia and early postoperative period for patients in the DEX group, whereas normal saline was administered in the same rate for the same duration for patients in the control (CTRL) group. The primary endpoint was the incidence of delirium during the first five days after surgery. Secondary endpoints included the cognitive function assessed on postoperative days 6 and 30, the overall incidence of non-delirium complications within 30 days after surgery, and the all-cause 30-day mortality. Results Two hundred eighty-five patients were enrolled and randomized. Dexmedetomidine did not decrease the incidence of delirium (4.9% [7/142] in the DEX group vs 7.7% [11/143] in the CTRL group; OR 0.62, 95% CI 0.23 to 1.65, p = 0.341). Secondary endpoints were similar between the two groups; however, the incidence of pulmonary complications was slightly decreased (OR 0.51, 95% CI 0.26 to 1.00, p = 0.050) and the percentage of early extubation was significantly increased (OR 3.32, 95% CI 1.36 to 8.08, p = 0.008) in the DEX group. Dexmedetomidine decreased the required treatment for intraoperative tachycardia (21.1% [30/142] in the DEX group vs 33.6% [48/143] in the CTRL group, p = 0.019), but increased the required treatment for postoperative hypotension (84.5% [120/142] in the DEX group vs 69.9% [100/143] in the CTRL group, p = 0.003). Conclusions Dexmedetomidine administered during anesthesia and early postoperative period

    Plasmonics has brought revolutionary advances to laser science by enabling deeply subwavelength nanolasers through surface plasmon amplification. However, the impact of plasmonics on other promising laser systems has so far remained elusive. Here, we present a class of random lasers enabled by three-dimensional plasmonic nanorod metamaterials. While dense metallic nanostructures are usually detrimental to laser performance due to absorption losses, here the lasing threshold keeps decreasing as the volume fraction of metal is increased up to ∼0.07. This is ∼460 times higher than the optimal volume fraction reported thus far. The laser supports spatially confined lasing modes and allows for efficient modulation of spectral profiles by simply tuning the polarization of the pump light. Full-field speckle-free imaging at micron-scales has been achieved by using plasmonic random lasers as the illumination sources. Our findings show that plasmonic metamaterials hold potential to enable intriguing coherent optical sources.

    Intubated patients are at risk of oral health problems. Although a variety of oral care regimens for intubated patients have been studied, there is a lack of research on the effects of combination oral care that includes tooth brushing, chlorhexidine and cold water. This open-labelled, randomized, controlled trial aimed to evaluate the effects of combination oral care on oral health status. Participants aged 20 years and older were recruited on the first day after intubation through convenience sampling in a medical intensive care unit. Random assignment was performed using an internet randomization service. The primary outcome was oral health status. Data were collected during May and June 2013. Participants were randomized to one of two groups (23 intervention and 21 control). The final analysis included 18 patients with combination oral care and 17 in the control group. The intervention group had better oral health (effect size = 1.56), less dry mouth and higher salivary pH than the control group. Any additional burden of providing combination oral care to patients who are mechanically ventilated is worthwhile in terms of clinical outcomes.

    Full Text Available Background: Non-alcoholic fatty liver disease (NAFLD is characterized by macro vesicular steatosis in the absence of alcohol. Patients with (NAFLD need extensive education and support in their treatment. Our aim was to investigate the effect of telenursing on liver enzymes (ALT and AST in patients with NAFLD. Methods: Our study is a randomized controlled clinical trial. In this study, 60 patients were enrolled from patients who referred to subspecialty gastrointestinal clinics affiliated to Shiraz University of Medical Sciences. Specialists confirmed their diseases by ultrasound and laboratory test. Simple randomization, based on random number table, was used to randomize the participants into intervention (N=30 and control (N=30 groups. Patients in both groups received dietary advice from a nutritionist and were trained to perform physical activities. Telephone intervention in the intervention group lasted for 12 weeks, in order to see the effect of follow up on the recommended diet and physical activities given by the specialist, while; the control group subjects were only followed up as usual by their physician. Results: The result of an independent t-test showed that the mean difference of liverEnzymesbetween the two groups was statistically significant (P<0.001. The difference of AST and ALT in the intervention and control groups was 18.03 , -1.27 and 40.70, 1.52, respectively. Conclusion: We found out that; telenursing could have a positive effect on reduction of liver enzymes (ALT, AST in patients with NAFLD.

    AIM: Rectal carcinoid tumors smaller than 10 mm can be resected with local excision using endoscopy. In order to remove rectal carcinoid tumors completely, we evaluated endoscopic mucosal resection with a ligation device in this pilot control randomized study.METHODS: Fifteen patients were diagnosed with rectal carcinoid tumor (less than 10 mm) in our hospital from 1993 to 2002. There were 9 males and 6 females,with a mean age 61.5 years (range, 34-77 years).The patientshad no complaints of carcinoid syndrome symptoms. Fifteen patients were randomly divided into 2 groups: 7 carcinoid tumors were treated by conventional endoscopic resection, and 8 carcinoid tumors were treated by endoscopic resection using a ligation device.RESULTS: All rectal carcinoid tumors were located at the middle to distal rectum. The size of the tumors varied from 3 mm to 10 mm and background characteristics of the patients were not different in the two groups.The rate of complete removal of carcinoid tumors using a ligation device (100%, 8/8) was significantly higher than that of conventional endoscopic resection (57.1%,4/7). The three patients had tumor involvement of deep margin, for which additional treatment was performed.No complications occurred during or after endoscopic resection using a ligation device. All patients in the both groups were alive during the 3-year observation period.CONCLUSION: Endoscopic resection using a ligation device is a useful and safe method for resection of small rectal carcinoid tumors.

    This study was designed to compare the therapeutic effects of topical clotrimazole and systemic fluconazole in pityriasis versicolor. A double-blind randomized controlled trial was carried out in the dermatological clinic of Gorgan, northern Iran, between April 2006 and May 2007. All consecutive patients with pityriasis versicolor were included and randomly divided into two groups. In the first group (G1), patients underwent treatment with a single dose of fluconazole capsule (400 mg) and placebo cream. In the second group (G2), patients underwent treatment with clotrimazole cream (twice daily) and placebo capsule. The course of treatment was 2 weeks. All subjects were re-evaluated 2, 4 and 12 weeks after the end of the therapeutic course. After 2 weeks, the rate of complete resolution of disease was significantly higher in G2 than G1 (49.1% vs 30%). After 4 weeks, 41 patients (81.2%) of G1 and 52 patients (94.9%) of G2 showed complete resolution. After 12 weeks, 46 patients (92%) in G1 and 45 patients (81.8%) in G2 showed complete resolution. Recurrence rate in G1 and G2 were 6% and 18.2%, respectively. No complications were seen in either group. In this study, clinical response at week 4 was greater in the clotrimazole group than the fluconazole group. Recurrence at week 12 after treatment was less with oral fluconazole than clotrimazole cream. So, for better evaluation, more studies need to be done.

    The role of cholinergic abnormalities in autism was recently evidenced and there is a growing interest in cholinergic modulation, emerging for targeting autistic symptoms. Galantamine is an acetylcholinesterase inhibitor and an allosteric potentiator of nicotinic receptors. This study aimed to evaluate the possible effects of galantamine as an augmentative therapy to risperidone, in autistic children. In this randomized, double-blind, placebo-controlled, parallel-group study, 40 outpatients aged 4-12 years whom had a diagnosis of autism (DSM IV-TR) and a score of 12 or higher on the Aberrant Behavior Checklist-Community (ABC-C) Irritability subscale were equally randomized to receive either galantamine (up to 24 mg/day) or placebo, in addition to risperidone (up to 2 mg/day), for 10 weeks. We rated participants by ABC-C and a side effects checklist, at baseline and at weeks 5 and 10. By the study endpoint, the galantamine-treated patients showed significantly greater improvement in the Irritability (P = 0.017) and Lethargy/Social Withdrawal (P = 0.005) subscales than the placebo group. The difference between the two groups in the frequency of side effects was not significant. In conclusion, galantamine augmentation was shown to be a relatively effective and safe augmentative strategy for alleviating some of the autism-related symptoms.

    Full Text Available This single center, randomized, and controlled study aimed to compare the effectiveness and safety of polyethylene glycol electrolyte lavage (PEG-EL solution and colonic hydrotherapy (CHT for bowel preparation before colonoscopy. A total of 196 eligible outpatients scheduled for diagnostic colonoscopy were randomly assigned to the PEG-EL (n=102 or CHT (n=94 groups. Primary outcome measures included colonic cleanliness and adverse effects. Secondary outcome measures were patient satisfaction and preference, colonoscopic findings, ileocecal arrival rate, examiner satisfaction, and cecal intubation time. The results show that PEG-EL group was associated with significantly better colonic cleanliness than CHT group, fewer adverse effects, and increased examiner satisfaction. However, the CHT group had higher patient satisfaction and higher diverticulosis detection rates. Moreover, the results showed the same ileocecal arrival rate and patient preference between the two groups (P>0.05. These findings indicate that PEG-EL is the preferred option in patients who followed the preparation instructions completely.

    Full Text Available Objectives. To study whether the reinforced feedback in virtual environment (RFVE is more effective than traditional rehabilitation (TR for the treatment of upper limb motor function after stroke, regardless of stroke etiology (i.e., ischemic, hemorrhagic. Design. Randomized controlled trial. Participants. Forty-four patients affected by stroke. Intervention. The patients were randomized into two groups: RFVE (N=23 and TR (N=21, and stratified according to stroke etiology. The RFVE treatment consisted of multidirectional exercises providing augmented feedback provided by virtual reality, while in the TR treatment the same exercises were provided without augmented feedbacks. Outcome Measures. Fugl-Meyer upper extremity scale (F-M UE, Functional Independence Measure scale (FIM, and kinematics parameters (speed, time, and peak. Results. The F-M UE (P=0.030, FIM (P=0.021, time (P=0.008, and peak (P=0.018, were significantly higher in the RFVE group after treatment, but not speed (P=0.140. The patients affected by hemorrhagic stroke significantly improved FIM (P=0.031, time (P=0.011, and peak (P=0.020 after treatment, whereas the patients affected by ischemic stroke improved significantly only speed (P=0.005 when treated by RFVE. Conclusion. These results indicated that some poststroke patients may benefit from RFVE program for the recovery of upper limb motor function. This trial is registered with NCT01955291.

    Full Text Available OBJECTIVE: the low degree of inflammation in obesity contributes to systemic metabolic dysfunction. Recent experimental studies proposed some effects of alteration in gut microbiota on inflammatory factors. This study aimed to assess the anti-inflammatory effects of a synbiotic supplement on inflammation markers in overweight and obese children and adolescents. METHODS: this randomized triple-masked controlled trial was conducted among 70 participants aged 6 to 18 years, with a body mass index (BMI equal or higher than the 85th percentile. They were randomly assigned into two groups of equal number to receive synbiotic or placebo for eight weeks. RESULTS: fifty-six of 70 participants (80% completed the study. Compared with the placebo group, the synbiotic group had significant decrease in mean values of tumor necrosis-α and interleukin-6, with significant increase in adiponectin; these changes were no longer significant after adjustment for BMI. There was no significant change in the mean values of high-sensitive C-reactive protein. CONCLUSION: the present findings suggest the positive influence of synbiotic supplementation on inflammation factors, which are dependent to its effect on weight reduction in overweight and obese children.

    Full Text Available Introduction: The management of asthma during adolescence has specific challenges and is likely influenced, to some extent, by the patient's belief in their ability to affect change, their self-efficacy. Bolstering self-efficacy could potentially improve an adolescent’s ability to self-manage their asthma. The aim of this study was to examine the effects of a triggers’ educational-modifying intervention on self-efficacy among adolescents diagnosed with asthma living in Iran. Methods: Sixty adolescents, aged 12 to 18 years, diagnosed with asthma participated in this randomized clinical trial. Participants randomly assigned to the control group received standard care while those assigned to the experimental group participated in a 5 week, nurse led, triggers modifying educational intervention in specialized clinics of lung in Tabriz, Iran. The self-efficacy scale developed by Bursh et al., was used for data collection. Results: The level of self- efficacy in two groups before intervention was not statistically significant, while the post intervention measures were statistically significant. Intervention was effective in improving adolescents’ self-efficacy. Conclusion: Since this type of intervention has the potential to improve Self- efficacy in adolescents with asthma, it is suggested that adolescence directly education about asthma triggers along with modulating triggers will be of value and parent‐centered could be diminished. The need for such interventions emphasizes in clinic and outpatient clinics.

    Full Text Available Caraway (Carum carvi L., a potent medicinal plant, is traditionally used for treating obesity. This study investigates the weight-lowering effects of caraway extract (CE on physically active, overweight and obese women through a randomized, triple-blind, placebo-controlled clinical trial. Seventy overweight and obese, healthy, aerobic-trained, adult females were randomly assigned to two groups (n=35 per group. Participants received either 30 mL/day of CE or placebo without changing their diet or physical activity. Subjects were examined at baseline and after 90 days for changes in body composition, anthropometric indices, and clinical and paraclinical variables. The treatment group, compared with placebo, showed a significant reduction of weight, body mass index, body fat percentage, and waist-to-hip ratio. No changes were observed in lipid profile, urine-specific gravity, and blood pressure of subjects. The results suggest that a dietary CE with no restriction in food intake, when combined with exercise, is of value in the management of obesity in women wishing to lower their weight, BMI, body fat percentage, and body size, with no clinical side effects. In conclusion, results of this study suggest a possible phytotherapeutic approach for caraway extract in the management of obesity. This trial is registered with NCT01833377.

    Chlorophyll c2 extracted from Sargassum horneri improved allergic symptoms in an animal model of allergic rhinitis. In the present study, we explored the efficacy of chlorophyll c2 in patients with seasonal allergic rhinitis. This was a single-center, randomized, double-blind placebo-controlled trial. Sixty-six patients aged 20-43 years, each with a 2-year history of seasonal allergic rhinitis, were randomly assigned to receive either a single daily dose (0.7 mg) of chlorophyll c2 or placebo for 12 weeks. The use of medications including H1-antihistamines and topical nasal steroids was recorded by rescue medication scores (RMSs) noted after 4, 8, and 12 weeks of treatment. Disease-specific quality of life was measured using the Japan Rhinitis Quality of Life Questionnaire (JRQLQ) both before and after 4, 8, and 12 weeks of treatment. The RMS at 8 weeks was significantly better in the chlorophyll c2 than the placebo group (mean RMS difference = -3.09; 95 % confidence interval = -5.96 to -0.22); the mean RMS at 4 weeks was only slightly better in the chlorophyll c2 group. The JRQLQ scores did not differ significantly between the two groups. Chlorophyll c2 would have a potential to be an alternative treatment for allergic rhinitis.

    Backcround Idiopathic choroidal neovascularization (ICNV) affects young patients and thus may have a significant impact on vision and life quality over a patient's lifespan.This study was designed to compare the visual outcome and retinal pigment epithelium (RPE) damage after photodynamic therapy (PDT) with small laser spot and PDT with standard laser spot for idiopathic choroidal neovascularization (ICNV).Methods This was a randomized controlled study.Fifty-two patients with ICNV were enrolled and randomly divided into a study group (small laser spot PDT,n=27) and a control group (standard laser spot PDT,n=25).Best corrected visual acuity (BCVA),optic coherence tomography (OCT) and fluorescein angiography (FA) findings were the main measurements.The patients were followed up 1 week,1,3,6,9 months and 1 year after PDT.Results BCVA improvement was statistically significantly higher in the study group than the control group at 6-month ((25.53±15.01) letters vs.(14.71±11.66) letters,P=0.025) and 9-month follow-ups ((27.53±17.78) letters vs.(15.59±12.21) letters,P=0.039).At 3-and 6-month follow-ups,the quadrants of RPE damage between the two groups varied significantly (P <0.001 and P=0.023,respectively).In each follow-up,the number of cases with decreased or unchanged leakage of choroidal neovascularization by FA and reduced subretinal fluid by OCT did not vary significantly between the two groups.Ten cases (37.0%) in the study group and eight cases (32.0%) in the control group suffered from recurrent CNV (P=0.703).Conclusions Better visual improvements,less RPE damage,a similar recurrent rate of CNV and change of subretinal fluid were observed in the small laser spot PDT group than in the standard laser spot PDT group for ICNV.

  17. Eliminating bias in randomized controlled trials: importance of allocation concealment and masking.

    Viera, Anthony J; Bangdiwala, Shrikant I

    2007-02-01

    Randomization in randomized controlled trials involves more than generation of a random sequence by which to assign subjects. For randomization to be successfully implemented, the randomization sequence must be adequately protected (concealed) so that investigators, involved health care providers, and subjects are not aware of the upcoming assignment. The absence of adequate allocation concealment can lead to selection bias, one of the very problems that randomization was supposed to eliminate. Authors of reports of randomized trials should provide enough details on how allocation concealment was achieved so the reader can determine the likelihood of success. Fortunately, a plan of allocation concealment can always be incorporated into the design of a randomized trial. Certain methods minimize the risk of concealment failing more than others. Keeping knowledge of subjects' assignment after allocation from subjects, investigators/health care providers, or those assessing outcomes is referred to as masking (also known as blinding). The goal of masking is to prevent ascertainment bias. In contrast to allocation concealment, masking cannot always be incorporated into a randomized controlled trial. Both allocation concealment and masking add to the elimination of bias in randomized controlled trials.

    The scope of transdermal analgesics have been limited to pain control following local trauma, muscle spasm, minor esthetic surgeries, or sports-related injuries. Its scope of application can be extended in the field of dentistry and minor oral surgical procedures. A total of 40 healthy patients between the age of 18 and 50 years with deeply carious, nontender mandibular molar tooth deemed unsalvageable which was indicated for extraction were taken into study of which subjects were divided into cases and controls. The data were analyzed with chi-square test and Mann-Whitney U test; the chi-square test showed significant association with expected outcome in visual analog scale pain scores, the two groups at 6th and 12th hour. A Mann-Whitney U test was performed to identify strength of association between two groups where there were significant association between all parameters except for pain interference with routine activities and dental health status(0.022, 0.001); the differences between two groups in these parameters were significant (Transdermal route seems to be comparable to oral diclofenac in post-extraction pain relief; further studies are required to confirm the results and safety for its use in various other dental situations.

    The aim of this study was to investigate the effects of Bobath-based individually designed trunk exercises on trunk control, upper and lower extremity function, and walking and balance in stroke patients. The main aim of treatment was to eliminate individual trunk impairments during various patient functions. The study was planned as an assessor-blinded, randomized controlled trial. A total of 22 patients volunteered to participate in the study. Trunk function, functional capacity, and gait were assessed with the Trunk Impairment Scale (TIS), stroke rehabilitation assessment of movement (STREAM), and a 10-m walking test, respectively. The Berg Balance Test (BBT), functional reach (FR), and timed up-and-go (TUG) tests were used to evaluate balance. After the initial assessment, the patients were divided randomly into two groups, the study group (12 patients) and the control group (10 patients). The mean age of the patients in the study group was 55.91 years (duration of stroke 58.66 months) and that of the control group was 54.00 years (duration of stroke 67.20 months). Individual training programs were determined for the patients in the study group, taking into consideration their evaluation results; and strengthening, stretching, range of motion, and mat exercises were determined for the control group according to their functional level. The participants in both groups were taken into the physiotherapy program for 12 weeks, 3 days a week for 1 hour a day. In group analyses, both groups showed improvement in STREAM, TIS, and TUG tests. Only the study group produced significant gains in the BBT, FR, and 10 m walking tests (P 0.05). Individually developed exercise programs in the Bobath concept improve trunk performance, balance, and walking ability in stroke patients more than do conventional exercises.

    Full Text Available Background: Lumbar radiculopathy is a disease of the spinal nerve root generally accompanied by radicular pain in dermatomal distribution and/or neurologic symptoms. The previous studies were focusing on finding the disability and pain caused due to Lumbar Radiculopathy. This study is focusing on the disability, pain, range of motion of the spine and SLR. The objective of the study is to evaluate the effectiveness of Mckenzie method with TENS on reducing symptoms and disability of Lumbar radiculopathy. Methods: In the present prospective study patients with Lumbar radicular pain due to disc herniation or prolapse at level L4, L5 & S1 were randomized into two groups – Group A and Group B. the study included 40 patients, with 20 in each group. The selection criteria was based on the following - with age group 22-55years, both sexes – male and female, with radicular pain in L4, L5 & S1 dermatomes, disabling leg pain for 6-12 weeks duration, evidence of disc herniation confirmed on MR imaging. The radicular pain was measured using the SLR test, pain was measured using the VAS scale of 0 – 100, disability was measured using the MODI and Lumbar Spine ROM was measured using the MMST. Group-A were treated with McKenzie methods with TENS and Group-B were treated with general exercise with TENS. Results: This study showed that there was a significant reduction of pain on the VAS, improvement in SLR, lumbar spine range of motion using MMST and disability using MODI for both the groups. The statistical analysis found that experimental group showed earlier control of all the outcome measures when compared to controlled group at the end of the 6th week. Conclusion: After 6 weeks of Mckenzie method with TENS intervention for 30 minutes for 5 days in week the statistical analysis concluded that the experimental group had significantly faster rates of reducing the symptoms of lumbar radiculopathy and reducing the disability due to lumbar radiculopathy.

    Clinical studies have shown that hyper-homocysteinemia is a potent independent risk factor for cardiovascular diseases, and many different methods have been investigated for lowering it in hemodialysis (HD) patients. Our study investigated the effect of Vitamin B 12 supplementation on serum homocysteine levels in these patients. This randomized trial was conducted on 140 HD patients. They were randomly distributed by lottery method into two groups: intervention and control. In the intervention group, 100 μg/mL of Vitamin B 12 was intravenously injected two times a week, for eight weeks. No intervention was performed in the control group. Serum levels of homocysteine, hemoglobin (Hb), and hematocrit (Hct) were measured at the beginning and again after eight weeks (2 months) of treatment. About 91% of the patients had hyperhomocysteinemia (serum homocysteine >15 μmol/L). The median baseline levels of serum homocysteine in the intervention and control groups were 31.9 and 26.9 μmol/L, respectively (P = 0.1). After eight weeks, the median homocysteine level reduced significantly in the Vitamin B 12 group to 22.2 versus 28.4 μmol/L in control group (P = 0.006). The mean Hb and Hct also changed significantly during our study (12.3 vs. 11.4 g/dL; P = 0.003 and 37.9 vs. 35.3%; P = 0.02, respectively). Our results demonstrated the existence of a statistical negative relationship between Vitamin B 12 and serum levels of homocysteine. Detailed investigations with larger sample sizes and longer-term use of Vitamin B 12 are recommended.

    Full Text Available Clinical studies have shown that hyper-homocysteinemia is a potent independent risk factor for cardiovascular diseases, and many different methods have been investigated for lowering it in hemodialysis (HD patients. Our study investigated the effect of Vitamin B 12 supplementation on serum homocysteine levels in these patients. This randomized trial was conducted on 140 HD patients. They were randomly distributed by lottery method into two groups: intervention and control. In the intervention group, 100 μg/mL of Vitamin B 12 was intravenously injected two times a week, for eight weeks. No intervention was performed in the control group. Serum levels of homocysteine, hemoglobin (Hb, and hematocrit (Hct were measured at the beginning and again after eight weeks (2 months of treatment. About 91% of the patients had hyperhomocysteinemia (serum homocysteine >15 μmol/L.

    To evaluate short-term effects of balance Vestibular Rehabilitation Therapy (VRT) on balance, dizziness symptoms and quality of life of the elderly with chronic Benign Paroxysmal Positional Vertigo (BPPV). In this randomized, single-blind and controlled trial, older adults with chronic BPPV were randomized into two groups, the experimental group (n = 7, age: 69 (65-78) years) and the control group (n = 7, age: 73 (65-76) years). Patients in the experimental group underwent balance VRT (50 min per session, two times a week) and Canalith Repositioning Maneuver (CRM) as required, for 13 weeks. The control group was treated using only CRM as required. Standing and dynamic balance, dizziness symptoms and quality of life were measured at the baseline, and at one, five, nine and thirteen weeks. There were no between-group differences in dizziness, quality of life and standing balance over the 13 weeks. Significant differences were observed in dynamic balance measures between groups (p balance tests in the control group. The patients who received additional balance VRT demonstrated better results in dynamic balance than those who received only CRM. Implications for Rehabilitation The findings that balance VRT in addition to CRM improves dynamic balance in elderly people with BPPV should be useful in guiding rehabilitation professionals' clinical decision making to design interventions for seniors suffering from BPPV; Improvements in tests of dynamic balance suggest that the risk of adverse consequences of BPPV in the elderly such as falls and fractures can be potentially reduced through implementation of CRM in conjunction with balance VRT; Lack of additional improvement in Visual Analogue Scale of dizziness and Dizziness Handicap Index suggests that addition of balance VRT does not influence dizziness symptomatology, per se, and CRM alone is effective to ameliorate vertiginous symptoms and potentially improve quality of life.

    Remote ischemic preconditioning (RIPC) is a phenomenon where a short period of ischemia in one organ protects against further ischemia in the other organs. We hypothesized that RIPC occurring in diabetic patients with ankle brachial index (ABI) between 0.70 and 0.90 were included with peripheral arterial disease, would make the better coronary flow resulted in the increasing ABI. This randomized clinical trial study was done in the Afshar Cardiovascular Hospital in Yazd between 2013 and 2014. Sixty participants were randomly divided into two groups (intervention and control groups). The intervention group was undergoing RIPC, and the control group was tested without RIPC. RIPC was stimulated by giving three cycles of 5 min of ischemia followed by 5 min of reperfusion of both upper arms using a blood pressure cuff inflated to 200 mm Hg (n = 30). This was compared with no RIPC group which consisted of placing a deflated blood pressure cuff on the upper limbs (n = 30). The mean of ABI level before intervention in the RIPC and control group group was 0.82 ± 0.055 and 0.83 ± 0.0603 (P = 0.347) respectively, with no significant difference. It was 0.86 ± 0.066 in the RIPC group compared the control 0.83 ± 0.0603 (P = 0.046). So levels of ABI were greater after intervention in the RIPC group. The mean of ABI level increase from 0.82 ± 0.05 to 0.86 ± 0.06 in RIPC group (P = 0.008). So the intervention group showed a significant increase in ABI. RIPC through using a simple, noninvasive technique, composing three cycles of 5 min-ischemia of both upper arms, showing a significant increase in ABI level in diabetic patients.

    Full Text Available Objective: This study investigated the efficacy of bupivacaine wound infusion for pain control and opioid sparing effect after cesarean delivery.Materials and methods: We conducted a randomized double blind, placebo controlled clinical trial on 60 parturients undergoing cesarean section at a university hospital in Tehran. Patients were randomized to receive a pump infusion system that was filled with either 0.25% bupivacaine or equal volume of distilled water. A catheter was placed above the fascia and connected to electronic pump for 24 hours. Postoperative analog pain scores and morphine consumption were assessed at 6, 12 and 24 hours. Also time interval to first ambulation, length of hospitalization, complications and patient satisfaction were recorded. Data were analyzed using the SPSS software and P < 0.05 was considered statistically significant. Mann-Whitney u-test, student t-test and chi-square were used. Results: There were no differences in patient demographics and length of hospitalization and patient-generated resting pain scores between the two groups. Pain scores after coughing and leg raise during the first 6 postoperative hours were significantly less in the Bupivacaine group (P<0.001. The total dose of morphine consumption during the 24 hours study period was 2.5 ± 2.5 mg vs. 7.3 ± 2.7 mg for the bupivacaine and control groups, respectively (P<0.001. Compared with the control group, time to first ambulation was shorter in the bupivacaine group (11± 5h vs. 16 ± 4h (P< 0.01. Conclusion: Bupivacaine wound infusion was a simple and safe technique that provides effective analgesia and reduces morphine requirements after cesarean delivery.

  6. Robust Fault-Tolerant Control for Uncertain Networked Control Systems with State-Delay and Random Data Packet Dropout

    2012-01-01

    Full Text Available A robust fault-tolerant controller design problem for networked control system (NCS with random packet dropout in both sensor-to-controller link and controller-to-actuator link is investigated. A novel stochastic NCS model with state-delay, model uncertainty, disturbance, probabilistic sensor failure, and actuator failure is proposed. The random packet dropout, sensor failures, and actuator failures are characterized by a binary random variable. The sufficient condition for asymptotical mean-square stability of NCS is derived and the closed-loop NCS satisfies H∞ performance constraints caused by the random packet dropout and disturbance. The fault-tolerant controller is designed by solving a linear matrix inequality. A numerical example is presented to illustrate the effectiveness of the proposed method.

    Aims. To evaluate the effectiveness of a brief suicide management training programme for Japanese medical residents compared with the usual lecture on suicidality. Methods. In this multi-center, clustered randomized controlled trial, the intervention group attended a structured suicide management programme and the control group, the usual lecture on depression and suicidality. The primary outcome was the difference in residents' cumulative competency score to manage suicidal persons from baseline (T0) to 1 month after the intervention (T2), determined using the Suicide Intervention Response Inventory (SIRI-1) score, at individual level. Results. Analysis of 114 residents (intervention group n = 65, control group n = 49) assigned to two clusters in each group revealed no change in SIRI-1 score from T0 to T2 or immediately after the intervention (T1) between the two groups. As a secondary analysis, discrepancy in judgement between the participants and Japanese suicidologists was examined immediately after the intervention in the adjusted model, with a mean difference in score of 9.98 (95% confidence interval: 4.39-15.56; p = 0.001). Conclusions. The structured programme was not proven to improve competency in suicide management when measured by the SIRI-1 score. Further elaboration of the programme and valid measurement of its outcome would be needed to show the program's effectiveness.

    To examine the effects of a new wearable type of lumbosacral support on low back pain. A total of 121 healthcare workers participated in this study. They were randomly allocated into the experimental and control groups and the former wore the support with signals of compression on the back by poor posture for the first 3 months. The control group remained on a waiting list for the first 3 months. Medical history, musculoskeletal symptoms, feeling in good posture, sleep habits, psychological distress, Roland-Morris Disability Questionnaire, and Somatosensory Amplification Scale (SSAS) were evaluated. The range of motion (ROM) in the shoulder and hip joints as well as spinal alignment were evaluated. Our primary concern was the difference in the change of low back pain measured by visual analog scale (VAS) between the two groups. A total of 54 participants in the experimental and 53 participants in the control groups were analyzed. VAS and SSAS scores as well as lumbar spinal ROM in the experimental group significantly decreased. Low back pain (OR=0.401, 95% CI=0.168-0.954) and neck pain in the experimental group (OR=0.198, 95% CI=0.052-0.748) significantly decreased. The new lumbar support reduced VAS and SSAS scores, lumbar spinal ROM, low back pain, and neck pain. This new type of lumbar support reduced low back pain among healthcare workers.

    [Purpose] To compare the effects of treadmill training with partial body weight support (TTPBWS) and conventional physical therapy (PT) on subjects with anterior cruciate ligament reconstructions. [Subjects and Methods] A total of 40 subjects were randomly allocated to either a treatment group or a control group. Subjects received either treadmill training with partial body weight support (treatment group) or conventional physical therapy (control group). The circumferences of the lower extremities, Holden classifications, 10-meter walking times and the International Knee Documentation Committee (IKDC) scores were compared at 12 and 24 weeks post-operation. The knee joint stability was tested at 24 weeks post-operation using a KT-1000. [Results] Significant differences were found between the two groups at the 12 weeks post-operation. For most of the measures, there was no significant difference between the groups at 24 weeks post-operation. Interestingly, for most of the measures, there was no significant difference between their values in the treatment group at 12 weeks and their values in the control group at 24 weeks post-operation. [Conclusion] The function of a subject’s lower extremities can be improved and the improvement was clearly accelerated by the intervention of treadmill training with partial body weight support, without compromising the stability of the knee joints in a given follow-up period.

    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.

    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.

    2013-01-01

    Full Text Available Aims. To evaluate the efficacy of rosiglitazone (TZD and electroacupuncture (EA combined therapy as a treatment for type 2 diabetes mellitus (T2DM patients by randomized single-blind placebo controlled clinical trial. Methods. A total of 31 newly diagnostic T2DM patients, who fulfilled the study's eligibility criteria, were recruited. The individuals were randomly assigned into two groups, the control group (TZD, N=15 and the experimental group (TZD + EA, N=16. Changes in their plasma free fatty acid (FFA, glucose, and insulin levels, together with their homeostasis model assessment (HOMA indices, were statistically compared before and after treatment. Hypoglycemic activity (% was also compared between these two groups. Results. There was no significant difference in hypoglycemic activity between the TZD and TZD + EA group. The effectiveness of the combined therapy seems to derive from an improvement in insulin resistance and a significant lowering of the secreted insulin rather than the effect of TZD alone on T2DM. The combined treatment had no significant adverse effects. A lower plasma FFA concentration is likely to be the mechanism that causes this effect. Conclusion. This combined therapy seems to suppress endogenous insulin secretion by improving insulin resistance via a mechanism involving a reduction in plasma FFA. This trial is registered with ClinicalTrials.gov NCT01577095.

    The use of prophylactic antibiotics to reduce postoperative complications in third molar surgery remains controversial. The study was a prospective, randomized, double blind, placebo-controlled clinical trial. 100 patients were randomly assigned to two groups. Each patient acted as their own control using the split-mouth technique. Two unilateral impacted third molars were removed under antibiotic cover and the other two were removed without antibiotic cover. The first group received antibiotics on the first surgical visit. On the second surgical visit (after 3 weeks), placebo capsules were given or vice versa. The second group received antibiotics with continued therapy for 2 days on the first surgical visit and on the second surgical visit (after 3 weeks) placebo capsules were given or vice versa. Pain, swelling, infection, trismus and temperature were recorded on days 3, 7 and 14 after surgery. Of 380 impactions, 6 sockets (2%) became infected. There was no statistically significant difference in the infection rate, pain, swelling, trismus, and temperature between the two groups (p>0.05). Results of the study showed that prophylactic antibiotics did not have a statistically significant effect on postoperative infections in third molar surgery and should not be routinely administered when third molars are removed in non-immunocompromised patients.

    2015-08-01

    Full Text Available Background: Medicinal plants are powerful health promoting nutritional agents. Among the vast library of medicinal plants Tinospora cordifolia (Willd. has been meagrely explored. It belongs to the family Menispermaceae and is a rich source of alkaloid and terpenes. It has hepatoprotective, antioxidant, immunostimulatory, hyperlipidemic, anticancer and antidiabetic properties. The stem contains berberine, palmatine, tembetarine, magnoflorine, tinosporin, tinocordifolin. The stem starch is highly nutritive and digestive. In modern medicine it is called the magical rejuvenating herb owing to its properties to cure many diseases. The stem contains higher alkaloid content than the leaves because of which it is approved for medicinal usage. With a host of phytochemical properties present in the stem, it may hold potential to manage dyslipidemia and dysglycemia, which otherwise has been proven only in pre-clinical studies. Objective: To study the impact of tinospora cordifolia stem supplementation on the glycemic and lipemic profile of subjects with diabetic dyslipidemia. Methods: Type 2 diabetics with dyslipidemia on oral hypoglycemic agents were enrolled. Baseline data on medical history, family history of lifestyle diseases, duration of diabetes diagnosis, drug profile, anthropometric data, dietary data and physical activity data was obtained along with a fasting blood sample for estimating high sensitivity C reactive protein (hs-CRP, hepatic, renal, lipid profile and glycated hemoglobin. The participants were randomized into either of the two groups; intervention group (n=29 received 250mg of encapsulated mature stem of tinospora cordifolia pre meal twice a day along with prescribed dyslipidemic agent and control group (n=30 only on dyslipidemic agents for a period of 60 days. After 60 days all the parameters were re-assessed to analyse the impact of the intervention. Results: Majority of the subjects in both the arms were in the 50-60 years age

    To compare the clinical efficacy on upper limb motor impairment in stroke between the interactive dynamic scalp acupuncture therapy and the traditional scalp acupuncture therapy. The randomized controlled trial and MINIMIZE layering randomization software were adopted. Seventy patients of upper limb with III to V grade in Brunnstrom scale after stroke were randomized into an interactive dynamic scalp acupuncture group and a traditional scalp acupuncture group, 35 cases in each one. In the interactive dynamic scalp acupuncture group, the middle 2/5 of Dingnieqianxiexian (anterior oblique line of vertex-temporal), the middle 2/5 of Dingniehouxiexian (posterior oblique line of vertex-temporal) and Dingpangerxian (lateral line 2 of vertex) on the affected side were selected as the stimulation areas. Additionally, the rehabilitation training was applied during scalp acupuncture treatment. In the traditional scalp acupuncture group, the scalp stimulation areas were same as the interactive dynamic scalp acupuncture group. But the rehabilitation training was applied separately. The rehabilitation training was applied in the morning and the scalp acupuncture was done in the afternoon. The results in Fugl-Meyer for the upper limb motor function (U-FMA), the Wolf motor function measure scale (WM- FT) and the modified Barthel index in the two groups were compared between the two groups before treatment and in 1 and 2 months of treatment, respectively. After treatment, the U-FMA score, WMFT score and the score of the modified Barthel index were all apparently improved as compared with those before treatment (all P acupuncture group was better than that in the traditional scalp acupuncture group (P acupuncture group were improved apparently as compared with those in the traditional scalp acupuncture group (P acupuncture group were not different significantly as compared with those in the traditional scalp acupuncture group (both P > 0.05).

    , and length of hospital stay. One hundred and sixty patients were randomized to receive either Mepore or Aquacel dressing. There was no significant difference in patient comfort between the two groups, but a higher cost in the Aquacel group despite significantly fewer changes of dressings in these patients....... No difference in the infection rate (13% vs. 11%, p=0.73), length of hospital stay, or wound complications was noted between the two groups. We conclude that although the Aquacel dressing needed significantly fewer changes than the conventional dressing, this did not influence the patient comfort. Moreover......, the traditional dressing scheme was significantly less expensive....

    To evaluate the accuracy of random plasma glucose in outpatients with type 2 diabetes mellitus for assessing glycaemic control. This comparative, cross-sectional study was conducted at the chemical pathology department of PNS Shifa Hospital, Karachi, from August 2015 to March 2016, and comprised data of subjects with type 2 diabetes mellitus who reported for evaluation of glycaemic control in non-fasting state. All blood samples were analysed for random plasma glucose and glycated haemoglobin. Random plasma glucose was compared as an index test with glycated haemoglobin considering it as reference standard at a value of less than 7% for good glycaemic control. SPSS 20 was used for data analysis. Of the 222 subjects, 93(42%) had good glycaemic control. Random plasma glucose showed strong positive correlation with glycated haemoglobin (p=0.000).Area under curve for random plasma glucose as determined by plotting receiver operating characteristic curve against glycated haemoglobin value of 7% was 0.89 (95% confidence interval: 0.849-0.930). Random plasma glucose at cut-off value of 150 mg/dl was most efficient for ruling out poor glycaemic control among patients with type 2 diabetes mellitus with 90.7% sensitivity and69.9% specificity and Youden's index of 0.606. Random plasma glucose may be used to reflect glycaemic control in adults with type 2 diabetes mellitus in areas where glycated haemoglobin is not feasible.

    Although mild therapeutic hypothermia is an effective neuroprotective strategy for cardiac arrest/resuscitated patients, and asphyxic newborns, recent randomized controlled trials (RCTs) have equally shown good neurological outcome between targeted temperature management at 33 °C versus 36 °C, and have not shown consistent benefits in patients with traumatic brain injury (TBI). We aimed to determine the effect of therapeutic hypothermia, while avoiding some limitations of earlier studies, which included patient selection based on Glasgow coma scale (GCS), delayed initiation of cooling, short duration of cooling, inter-center variation in patient care, and relatively rapid rewarming. We conducted a multicenter RCT in patients with severe TBI (GCS 4-8). Patients were randomly assigned (2:1 allocation ratio) to either therapeutic hypothermia (32-34 °C, n = 98) or fever control (35.5-37 °C, n = 50). Patients with therapeutic hypothermia were cooled as soon as possible for ≥ 72 h and rewarmed at a rate of fever control groups, respectively. There were no significant differences in the likelihood of poor neurological outcome (relative risk [RR] 1.24, 95% confidence interval [CI] 0.62-2.48, p = 0.597) or mortality (RR 1.82, 95% CI 0.82-4.03, p = 0.180) between the two groups. We concluded that tight hemodynamic management and slow rewarming, together with prolonged therapeutic hypothermia (32-34 °C) for severe TBI, did not improve the neurological outcomes or risk of mortality compared with strict temperature control (35.5-37 °C).

    Full Text Available Introduction. Patients with chronic lateral elbow (LE tendinopathy, commonly known as tennis elbow, often experience prolonged symptoms and frequent relapses. Astym treatment, evidenced in animal studies to promote the healing and regeneration of soft tissues, is hypothesized to improve outcomes in LE tendinopathy patients. This study had two objectives: (1 to compare the efficacy of Astym treatment to an evidence-based eccentric exercise program (EE for patients with chronic LE tendinopathy, and (2 to quantify outcomes of subjects non-responsive to EE who were subsequently treated with Astym treatment.Study Design. Prospective, two group, parallel, randomized controlled trial completed at a large orthopedic center in Indiana. Inclusion criteria: age range of 18–65 years old, with clinical indications of LE tendinopathy greater than 12 weeks, with no recent corticosteriod injection or disease altering comorbidities.Methods. Subjects with chronic LE tendinopathy (107 subjects with 113 affected elbows were randomly assigned using computer-generated random number tables to 4 weeks of Astym treatment (57 elbows or EE treatment (56 elbows. Data collected at baseline, 4, 8, 12 weeks, 6 and 12 months. Primary outcome measure: DASH; secondary outcome measures: pain with activity, maximum grip strength and function. The treating physicians and the rater were blinded; subjects and treating clinicians could not be blinded due to the nature of the treatments.Results. Resolution response rates were 78.3% for the Astym group and 40.9% for the EE group. Astym subjects showed greater gains in DASH scores (p = 0.047 and in maximum grip strength (p = 0.008 than EE subjects. Astym therapy also resolved 20/21 (95.7% of the EE non-responders, who showed improvements in DASH scores (p < 0.005, pain with activity (p = 0.002, and function (p = 0.004 following Astym treatment.

    2014-09-01

    There have been a number of small-sized underpowered randomized controlled trials to assess effects of telmisartan on flow-mediated dilatation (FMD). To determine whether telmisartan increases FMD, we performed a meta-analysis of these trials. MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials were searched through December 2013. Eligible studies were prospective randomized controlled trials of telmisartan reporting FMD as an outcome. Search terms included: telmisartan; endothelial function/dysfunction; flow-mediated dilation/dilatation/vasodilation/vasodilatation; and randomized, randomly or randomization. Included studies were reviewed to determine the number of patients randomized, mean duration of treatment and percent changes of FMD. Of 25 potentially relevant articles screened initially, seven reports of randomized trials enrolling a total of 398 patients were identified and included. A pooled analysis of the seven trials demonstrated a statistically significant increase in FMD by 48.7%, with telmisartan relative to control in the random-effects model (mean difference, 48.72%; 95% confidence interval, 15.37-82.08%; P for effect=0.004; P for heterogeneity telmisartan, which suggests that telmisartan may improve endothelial dysfunction.

    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.

    The continuous increase in elderly and oldest-old population, and subsequent rise in prevalence of chronic neurological diseases like Alzheimer's disease (AD) and Parkinson's disease (PD), are a major challenge for healthcare systems. These two conditions are the most prevalent neurodegenerative diseases in older persons and physicians should engage treatment for these patients. In this field, Randomized Clinical Trials (RCTs) specifically focused on elderly populations are still lacking. The aim of this study was to identify RCTs conducted among AD and PD and to examine the difference between mean age of enrollment and incidence of these two neurodegenerative diseases. We found that the scenario is different between PD and AD. In particular, the enrollment for PD trials seems to include younger persons than AD, although the incidence of both diseases is similar and highest after 80 years old. The consequence of these results could influence conclusive guidelines of treatment in older parkinsonian patients.

    In the last few years, not many studies on the use of robot-assisted therapy to recover hand function in acute stroke patients have been carried out. This randomized-controlled observer trial is aimed at evaluating the effects of intensive robot-assisted hand therapy compared with intensive occupational therapy in the early recovery phases after stroke with a 3-month follow-up. Twenty acute stroke patients at their first-ever stroke were enrolled and randomized into two groups. The experimental treatment was performed using the Amadeo Robotic System. Control treatment, instead, was carried out using occupational therapy executed by a trained physiotherapist. All participants received 20 sessions of treatment for 4 consecutive weeks (5 days/week). The following clinical scales, Fugl-Meyer Scale (FM), Medical Research Council Scale for Muscle Strength (hand flexor and extensor muscles) (MRC), Motricity Index (MI) and modified Ashworth Scale for wrist and hand muscles (MAS), were performed at baseline (T0), after 20 sessions (end of treatment) (T1) and at the 3-month follow-up (T2). The Barthel Index was assessed only at T0 and T1. Evidence of a significant improvement was shown by the Friedman test for the FM [experimental group (EG): P=0.0039, control group (CG): Probot-assisted treatment on hand recovery functions in individuals with acute stroke. The robotic rehabilitation treatment may contribute toward the recovery of hand motor function in acute stroke patients. The positive results obtained through the safe and reliable robotic rehabilitation treatment reinforce the recommendation to extend it to a larger clinical practice.

    Full Text Available Current standardized treatments for cognitive impairment in attention-deficit/hyperactivity disorder remain limited and their efficacy restricted. Transcranial direct current stimulation (tDCS is a promising tool for enhancing cognitive performance in several neuropsychiatric disorders. Nevertheless, the effects of tDCS in reducing cognitive impairment in patients with attention-deficit/hyperactivity disorder (ADHD have not yet been investigated.A parallel, randomized, double-blind, sham-controlled trial was conducted to examine the efficacy of tDCS on the modulation of inhibitory control in adults with ADHD. Thirty patients were randomly allocated to each group and performed a go/no-go task before and after a single session of either anodal stimulation (1 mA over the left dorsolateral prefrontal cortex or sham stimulation.A nonparametric two-sample Wilcoxon rank-sum (Mann-Whitney test revealed no significant differences between the two groups of individuals with ADHD (tDCS vs. sham in regard to behavioral performance in the go/no go tasks. Furthermore, the effect sizes of group differences after treatment for the primary outcome measures-correct responses, impulsivity and omission errors--were small. No adverse events resulting from stimulation were reported.According to these findings, there is no evidence in support of the use of anodal stimulation over the left dorsolateral prefrontal cortex as an approach for improving inhibitory control in ADHD patients. To the best of our knowledge, this is the first clinical study to assess the cognitive effects of tDCS in individuals with ADHD. Further research is needed to assess the clinical efficacy of tDCS in this population.ClinicalTrials.gov NCT01968512.

    The current evidence supports the clinical benefits of late umbilical cord clamping. These benefits include increased blood volume and total body iron. Furthermore, delayed cord clamping facilitates the transplantation of stem cells, which helps the development of infant bodily systems. However, due to concerns related to postpartum hemorrhaging and neonate jaundice, most maternity units still clamp the cord immediately after a child is born. This study investigates the impact of delaying cord clamping on neonatal jaundice and postpartum hemorrhage. A randomized, controlled trial was conducted at a regional teaching hospital in northern Taiwan. One hundred and five healthy nulliparous women at 36 weeks of pregnancy were included and allocated randomly to the experiment group (n=44) and the control group (n=61). Participants in the experiment group received delayed cord clamping (DCC) at 3 minutes after delivery. Participants in the control group received early cord clamping (ECC) at around 1 minute after delivery. Clinical measures of the outcomes were measured by the infant transcutaneous bilirubin levels (TcB) and postpartum hemorrhage at birth. A structured questionnaire and biophysical measures were used to collect data on participant demographics, obstetrical information, maternal blood loss at birth, neonate weight and TcB level at hospitalization, and whether or not the infant received phototherapy at 4-7 days postpartum. Overall, there was no significant difference between the two groups in terms of neonatal jaundice, maternal hemorrhage at birth, and phototherapy rates at time of hospitalization and at 4-7 days postpartum. The findings of the present study support that late umbilical cord clamping does not increase the risk of maternal postpartum hemorrhaging or neonate jaundice. Thus, we suggest that clinicians inform clients during prenatal classes of the benefits of delayed cord clamping and also use current, evidence-based knowledge to dispel client

    The purpose of this study was to assess the impact of the Virtual Hope Box (VHB), a smartphone app to improve stress coping skills, suicidal ideation, and perceived reasons for living among patients at elevated risk of suicide and self-harm. The authors conducted a parallel-group randomized controlled trial with two groups of U.S. service veterans in active mental health treatment who had recently expressed suicidal ideation. Between March 2014 and April 2015, 118 patients were enrolled in the study. Participants were assigned to use the VHB (N=58) or to a control group that received printed materials about coping with suicidality (N=60) to supplement treatment as usual over a 12-week period. Three measures-the Coping Self-Efficacy Scale, Beck Scale for Suicidal Ideation, and Brief Reasons for Living Inventory-were collected at baseline (before randomization) and three, six, and 12 weeks. Secondary measures-the Interpersonal Needs Questionnaire, Perceived Stress Scale, and Columbia-Suicide Severity Rating Scale-were collected at baseline and 12 weeks. VHB users reported significantly greater ability to cope with unpleasant emotions and thoughts (Coping Self-Efficacy Scale) at three (b=2.41, 95% confidence interval [CI]=.29-4.55) and 12 weeks (b=2.99, 95% CI=.08-5.90) compared with the control group. No significant advantage was found on other outcome measures for treatment augmented by the VHB. The VHB is a demonstrably useful accessory to treatment-an easily accessible tool that can increase stress coping skills. Because the app is easily disseminated across a large population, it is likely to have broad, positive utility in behavioral health care.

    Full Text Available Aims and Objectives: To assess the effect of Comprehensive Yogic Breathing Program on glycemic control, quality of life, and cardiac autonomic functions in diabetes. Material and Methods: This is a prospective randomized controlled intervention trial. Cardiac autonomic functions were assessed in 120 diabetics. Patients were randomized into two groups, one group receiving standard therapy for diabetes (n = 56 and the other group receiving standard therapy for diabetes and comprehensive yogic breathing program (n = 64. Standard therapy included advice on diet, walk, and oral antidiabetic drugs. Comprehensive yogic breathing program was an interactive session in which Sudarshan kriya yoga, a rhythmic cyclical breathing, preceded by Pranayam was taught under guidance of a certified teacher. Change in fasting, post prandial blood sugars, glycated hemoglobin, and quality of life were assessed. Cardiac autonomic function tests were done before and six months after intervention. Results: There was significant improvement in psychological (P = 0.006 and social domains (P = 0.04 and total quality of life (P = 0.02 in the group practicing comprehensive yogic breathing program as compared to the group following standard therapy alone. In the group following breathing program, the improvement in sympathetic cardiac autonomic functions was statistically significant (P = 0.01, while the change in the standard group was not significant (P = 0.17. When both parasympathetic and sympathetic cardiac autonomic functions were considered, there was a trend toward improvement in patients following comprehensive yogic breathing program (P = 0.07. In the standard therapy group, no change in cardiac autonomic functions was noted (P = 0.76. The parameters of glycemic control were comparable in both groups. Conclusion: There was significant improvement in quality of life and cardiac autonomic functions in the diabetes patients practicing comprehensive yogic breathing

    Full Text Available Abstract Background Loss of knee extension and a deficit in quadriceps strength are frequently found following anterior cruciate ligament (ACL reconstruction. The aim of this study was to investigate whether the addition of Eletromyographic Biofeedback (EMG BFB therapy for the vastus medialis muscle to the in the early phase of the standard rehabilitation programme could improve the range of knee extension and strength after ACL reconstruction more than a standard rehabilitation programme. The correlation between EMG measurement and passive knee extension was also investigated. Method Sixteen patients, all of whom underwent endoscopic ACL reconstruction using patellar tendon autograft, were randomly assigned to two groups: • Control group (8 patients: standard rehabilitation protocol; with full weight-bearing postoperative, knee brace (0° extension, 90° flexion, electrical stimulation, aquatics and proprioceptive training. • The EMG BFB group (8 patients: EMG BFB was added to the standard rehabilitation protocol within the first postoperative week and during each session for the next 6 weeks. Each patent attended a total of 16 outpatient physiotherapy sessions following surgery. High-Heel-Distance (HHD Test, range of motion (ROM and integrated EMG (iEMG for vastus medialis were measured preoperatively, and at the 1, 2, 4 and 6-week follow ups. Additionally, knee function, swelling and pain were evaluated using standardized scoring scales. Results At 6 weeks, passive knee extension (p  0.01 differences were found between the two groups for the assessment of knee function, swelling and pain. Conclusion The results indicate that EMG BFB therapy, in the early phase of rehabilitation after ACL reconstruction, is useful in enhancing knee extension. Improved innervation of the vastus medialis can play a key role in the development of postoperative knee extension. EMG BFB therapy is a simple, inexpensive and valuable adjunct to conventional

    We evaluated the effect of timer watch treatment in addition to standard urotherapy in children with overactive bladder and daytime urinary incontinence. A total of 60 children with daytime urge incontinence were included in the study. Following a 4-week run-in period of standard urotherapy children were randomized to 12 weeks of standard urotherapy with or without a timer watch. Incontinence episodes were registered and 48-hour bladder diaries were obtained before randomization, and at weeks 1, 11 and 12. Long-term response was evaluated at 7 months. Two children became continent during the run-in period. Before intervention children in the timer group were slightly more wet than children in the standard urotherapy group (median 7 [IQR 25% to 75% 6 to 7] vs 6 [3 to 7] wet days per week, p timer assisted urotherapy had significantly fewer wet days per week (median 2, IQR 25% to 75% 0 to 5) vs those undergoing standard urotherapy alone (5, 2.75 to 6.75, p timer group 18 children (60%) achieved a greater than 50% decrease in incontinence episodes, compared to only 5 (18%) treated without timer assistance. Nine patients (30%) in the timer group and no child in the standard urotherapy group achieved complete daytime continence. The timer increased compliance with the timed voiding regimen. At 7 months of followup 60% of children in the timer group were still continent in the daytime. A programmable timer watch significantly improves the effect of standard urotherapy. When using the timer watch as a supplement to standard urotherapy 60% of the children obtained complete and sustainable daytime continence. Copyright © 2010 Ameri
