A protocol for a randomized controlled trial of exposure and response prevention for veterans with obsessive compulsive disorder. Contemp Clin Trials 2024; 138:107445. [PMID: 38237674 DOI: 10.1016/j.cct.2024.107445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 01/02/2024] [Accepted: 01/15/2024] [Indexed: 01/23/2024]
Abstract
BACKGROUND Obsessive compulsive disorder (OCD) is effectively treated with exposure and response prevention (ERP), yet very few veterans receive ERP for OCD within the Veterans Health Administration (VHA). Veterans are a clinically complex population, and no prior research has evaluated the effectiveness of ERP in veterans with OCD or comorbid OCD and posttraumatic stress disorder (PTSD). Given the limited accessibility of ERP-trained providers within VHA, assessment of video telehealth (VTH) delivery of ERP is warranted. METHODS A sample of 160 veterans with OCD (80 diagnosed with comorbid PTSD) will be randomly assigned to receive up to 16 sessions of ERP or a stress management training control delivered via VTH. Assessments will occur at baseline, posttreatment, and 6-month follow-up. The primary outcome will evaluate the impact of ERP on participants' functioning, and secondary outcomes will include quality of life and OCD symptoms. At posttreatment, qualitative interviews with veterans, clinicians, and administrators will explore barriers and facilitators to treatment delivery, and the implementation potential of ERP. CONCLUSIONS Results will provide direction for the treatment of OCD and comorbid PTSD in veterans, as well as guidance for future implementation efforts for ERP within VHA.

Broad-spectrum antibiotic prophylaxis in tumor and infected orthopedic surgery-the prospective-randomized, microbiologist-blinded, stratified, superiority trials: BAPTIST Trials. Trials 2024; 25:69. [PMID: 38243311 PMCID: PMC10799415 DOI: 10.1186/s13063-023-07605-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Accepted: 08/26/2023] [Indexed: 01/21/2024] Open
Abstract
BACKGROUND The perioperative antibiotic prophylaxis with 1st or 2nd generation cephalosporins is evidence-based in orthopedic surgery. There are, however, situations with a high risk of prophylaxis-resistant surgical site infections (SSI). METHODS We perform a superiority randomized controlled trial with a 10% margin and a power of 90% in favor of the broad-spectrum prophylaxis. We will randomize orthopedic interventions with a high risk for SSI due to selection of resistant pathogens (open fractures, surgery under therapeutic antibiotics, orthopedic tumor surgery, spine surgery with American Society of Anesthesiologists (ASA) score ≥ 3 points) in a prospective-alternating scheme (1:1, standard prophylaxis with cefuroxime versus a broad-spectrum prophylaxis of a combined single-shot of vancomycin 1 g and gentamicin 5 mg/kg parenterally). The primary outcome is "remission" at 6 weeks for most orthopedic surgeries or at 1 year for surgeries with implant. Secondary outcomes are the risk for prophylaxis-resistant SSI pathogens, revision surgery for any reason, change of antibiotic therapy during the treatment of infection, adverse events, and the postoperative healthcare-associated infections other than SSI within 6 weeks (e.g., urine infections or pneumonia). With event-free surgeries to 95% in the broad-spectrum versus 85% in the standard prophylaxis arm, we need 2 × 207 orthopedic surgeries. DISCUSSION In selected patients with a high risk for infections due to selection of prophylaxis-resistant SSI, a broad-spectrum combination with vancomycin and gentamycin might prevent SSIs (and other postoperative infections) better than the prophylaxis with cefuroxime.

Addressing help-seeking, stigma and risk factors for suicidality in secondary schools: short-term and mid-term effects of the HEYLiFE suicide prevention program in a randomized controlled trial. BMC Public Health 2024; 24:113. [PMID: 38191336 PMCID: PMC10773084 DOI: 10.1186/s12889-023-17557-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Accepted: 12/21/2023] [Indexed: 01/10/2024] Open
Abstract
BACKGROUND Suicidal ideation and suicide attempts present a serious public health concern among adolescents and young adults. School-based suicide prevention programs are a key tool for addressing this problem. However, more research is necessary to assess their effectiveness, acceptability, and safety. In response, the HEYLiFE suicide prevention program was developed to enhance help-seeking, reduce stigma towards suicidal peers and diminish risk factors for suicidality. This article presents the evaluation findings of the HEYLiFE program in German secondary schools. METHODS We conducted a randomized-controlled trial measuring short-term pre-post within-group effects in the intervention group only and mid-term effects at 6-months-follow-up compared to a waitlist-control group. Schools were assigned randomly to the intervention or control group (no blinding). We recruited students ≥12 years of age. Primary outcomes were knowledge about suicidality, attitudes towards suicidality, stigma towards a suicidal peer, help-seeking intentions and behaviours, risk factors for suicidality. The data was analysed with linear mixed models and generalized linear mixed models. RESULTS A total of N = 745 students participated (n = 353 intervention group, n = 392 control group). We observed favourable short-term effects on knowledge, attitudes towards suicidality and fear towards a suicidal peer. Unexpectedly, the program also led to an increase in desire for social distance and a decrease in prosocial emotions towards a suicidal peer. The mid-term effects of the program were exclusively favourable, resulting in enhanced attitudes towards help-seeking while protecting from a sharper rise in risk-factors for suicidality and from an increase in social distance. The program had more favourable effects on females and on students aged >13 years. The program was well-received by the students, and no serious adverse events were reported. CONCLUSIONS These findings demonstrate the effectiveness of the HEYLiFE universal suicide prevention program in addressing variables associated with suicidal ideation and suicide attempts among adolescents on the mid-term. The short-term negative effects on stigma and more negative effects on males should be addressed in the future. Future evaluation studies should examine its effects on suicidality and its effectiveness within populations at high risk. TRIAL REGISTRATION The study was preregistered in the German Clinical Trials Register (registration number: DRKS00017045; registration date: 02/04/2019).

Abstract
BACKGROUND Asthma is a chronic respiratory disease with symptoms of attacks of wheezing, shortness of breath, & tightness in the chest. Even with pre-existing treatment exacerbations go uncontrolled. OBJECTIVE This study compared asthma control in yoga intervention versus non-yoga intervention group using Asthma Control Test. METHODS In this randomized controlled trial, participants were allocated into two groups in 1:1 ratio - yoga intervention versus non-yoga intervention. Only outcome assessor was blinded. Sample size of 200 was calculated. Individuals between 18 and 60 years of age, diagnosed with mild to moderate asthma with no exacerbation in past one month were screened and enrolled. Per-protocol analysis was done to assess the outcomes of Asthma Control Test and expenditure.(CTRI/2020/02/023534) RESULTS: A total of 192 participants enrolled, 165 completed this study who were considered for final analysis. A significant difference (p < 0.001) was found between yoga and non-yoga exercise group at 13 weeks. Expenses were more in non-yoga exercise group. CONCLUSION Our findings confirm that yoga exercise with routine medical care reduces exacerbations and improves asthma control.

Randomized, double-blind, sham-controlled trial to evaluate the efficacy and tolerability of electroconvulsive therapy in patients with clozapine-resistant schizophrenia. Schizophr Res 2023:S0920-9964(23)00421-8. [PMID: 38151432 DOI: 10.1016/j.schres.2023.11.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 11/20/2023] [Accepted: 11/21/2023] [Indexed: 12/29/2023]
Abstract
There is no established treatment for patients with clozapine-resistant schizophrenia (CRS). Clozapine augmentation strategies with antipsychotics or others substances are effective in comparison with placebo while and Electroconvulsive therapy (ECT) showed to be effective in comparison with treatment as usual (TAU) but not with placebo (sham-ECT). In the present double- blind randomized controlled trial, we compared 40 outpatients who received 20 sessions of ECT (n = 21) or sham-ECT (n = 19) (age = 37.40 ± 9.62, males = 77.5 %, illness duration = 14.95 ± 8.32 years, mean total Positive and Negative Syndrome Scale (PANSS) = 101.10 ± 24.91) who fulfilled well-defined CRS criteria including baseline clozapine plasma levels ≥350 ng/mL. The primary outcome was the ≥50 % PANSS Total Score reduction; secondary outcomes were the scores of the PANSS subscales, PANSS five-factor dimensions, PANSS-6 and the Calgary Depression Rating Scale (CDRS). Treatment response was analyzed by percentage reduction, Linear Mixed Models and effect sizes. At baseline both groups showed no differences except for years of school education (included as a covariate). At endpoint, only 1/19 of the completers (5.26 %) in the ECT group and 0/17 in the sham-ECT group showed a ≥50 % total PANSS score reduction. Both groups showed no significant differences of the total PANSS score (F = 0.12; p = 0.73), Positive (F = 0.27, p = 0.61), Negative (F = 0.25, p = 0.62), and General Psychopathology scores (F = 0.01, p = 0.94) as well for all PANSS five factors, the PANSS-6 and CDRS. Thus, the present study found no evidence that ECT is better than Sham-ECT in patients with CRS. Future sham-ECT controlled studies with larger sample sizes are warranted to test the efficacy of ECT for patients with CRS.

Abstract
PURPOSE The aim of this study was to assess the effect of systematic lateral retinacular release (LRR) on anterior knee pain (AKP), as well as its impact on the functional and radiological outcomes after total knee arthroplasty (TKA) with patellar resurfacing. METHODS A prospective randomized study was designed. It included patients scheduled for a TKA procedure with patellar resurfacing, who were recruited and randomized into either the LRR group or the non-release group. 198 patients were included in the final analysis. The pressure pain threshold (PPT) assessed by pressure algometry (PA), the visual analogue scale (VAS), Feller's patellar score, the Knee Society Score (KSS), patellar height, and patellar tilt were recorded both preoperatively and at the 1-year follow-up. The Mann-Whitney U test was performed to determine comparisons between both groups as well as to determine differences' intragroup. RESULTS Relative to the clinical variables and scores, no difference was detected between the two groups at the 1-year follow-up (p = n.s.). However, there was a slight difference in patellar tilt (0.1º vs. 1.4º, p = 0.044), with higher tilt values in the non-release group. There was no difference in terms of improvement in the clinical and radiological scores and variables recorded between the two groups (p = n.s.). CONCLUSION LRR in primary TKA with patellar resurfacing does not show an improvement in AKP and functional outcomes over patellar resurfacing without release. LEVEL OF EVIDENCE I.

Are gains in emotional symptoms and emotion-regulation competencies after the REThink therapeutic game maintained in the long run? A 6-month follow-up. Eur Child Adolesc Psychiatry 2023; 32:1853-1862.

Abstract
Emotional disorders are the most prevalent mental health conditions affecting children and adolescents. Thus, it becomes essential to develop and test early intervention strategies that are accessible, attractive, and can effectively improve their emotional functioning. A randomized control trial compared the prevention effects of the REThink therapeutic game to those of a standard face-to-face prevention program, and a waitlist which was transformed at follow-up into care as usual. Out of 142 healthy children and adolescents who completed the intervention stage, 137 (mean age: 12.84, SD: 1.97) completed a follow-up assessment measuring emotional symptoms, depressive mood and emotion regulation. We also tested potential moderators of its long-term effects, such as parental psychological control, parent attachment and childhood trauma. Our results highlighted the fact that the REThink intervention had a durable impact on the children's mental health and their ability to regulate their emotions. Moreover, we found that trauma, parent psychological control and parent attachment moderated the maintenance of the improvements. Future research needs to further document how to personalize the game and prevention program components to better address the characteristics of the youths at risk for mental health problems.

Impact of the CARE Tipping Point Program in Nepal on adolescent girls' agency and risk of child, early, or forced marriage: Results from a cluster-randomized controlled trial. SSM Popul Health 2023; 22:101407. [PMID: 37251506 PMCID: PMC10214831 DOI: 10.1016/j.ssmph.2023.101407] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 04/14/2023] [Accepted: 04/15/2023] [Indexed: 05/31/2023] Open
Abstract
Background Girl child, early, and forced marriage (CEFM) persists in South Asia, with long-term effects on well-being. CARE's Tipping Point Initiative (TPI) sought to address the gender norms and inequalities underlying CEFM by engaging participant groups on programmatic topics and supporting community dialogue to build girls' agency, shift power relations, and change norms. We assessed impacts of the CARE TPI on girls' multifaceted agency and risk of CEFM in Nepal. Methods The quantitative evaluation was a three-arm, cluster-randomized controlled trial (control; Tipping Point Program [TPP]; Tipping Point Plus Program [TPP+] with emphasized social-norms change). Fifty-four clusters of ∼200 households each were selected from two districts (27:27) with probability proportional to size and randomized evenly to study arms. A pre-baseline census identified unmarried girls 12-16 years (1,242) and adults 25 years or older (540). Questionnaires covered marriage; agency; social networks/norms; and discrimination/violence. Baseline participation was 1,140 girls and 540 adults. Retention was 1,124 girls and 531 adults. Regression-based difference-in-difference models assessed program effects on 15 agency-related secondary outcomes. Cox-proportional hazard models assessed program effects on time to marriage. Sensitivity analyses assessed the robustness of findings. Results At follow-up, marriage was rare for girls (<6.05%), and 10 secondary outcomes had increased. Except for sexual/reproductive health knowledge (coef.=.71, p=.036) and group membership (coef.=.48, p=.026) for TPP + versus control, adjusted difference-in-difference models showed no program effects on secondary outcomes. Results were mostly unmoderated by community mean: gender norms, household poverty, or women's schooling attainment. Cox proportional hazard models showed no program effect on time-to-marriage. Findings were robust. Discussion Null findings of the Nepal TPI may be attributable to low CEFM rates at follow-up, poor socio-economic conditions, COVID-19-related disruptions, and concurrent programming in control areas. As COVID-19 abates, impacts of TPP/TPP + on girls' agency and marriage, alone and with complementary programming, should be assessed. Trial registration number NCT04015856.

Assessing the effectiveness and the mechanisms of the Social-Emotional Prevention Program for Preschoolers: Findings from a universal school-based intervention. J Sch Psychol 2023; 98:206-223. [PMID: 37253580 DOI: 10.1016/j.jsp.2023.04.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 01/24/2023] [Accepted: 04/20/2023] [Indexed: 06/01/2023]
Abstract
The Social-Emotional Prevention Program (SEP) encompasses a multifaceted approach (classroom curriculum, with teacher and parent training) intended to increase preschool children's social adjustment, as well as to reduce risk of emotional and behavioral problems. The present study's focus was on implementing the technology-assisted SEP version and was aimed at (a) investigating the program's effectiveness on children's social-emotional competencies and parental practices, as well as (b) testing the program's conceptual framework, with an emphasis on children's emotion regulation (ER) skills and parental emotion socialization practices as explanatory intervention mechanisms. A randomized-controlled trial (RCT) was conducted with five schools assigned to either the intervention or to a comparison condition (wait-list control). Structural equation models (SEM) and complier average causal effects (CACE) were conducted to evaluate SEP effectiveness on teacher- and parent-rated child outcomes (primary outcomes) and parenting behaviors (secondary outcomes). Findings from the present study indicated that (a) SEP fosters increased social-emotional competencies and increased use of adaptive ER strategies, with teacher and parent ratings converging to support these outcomes; (b) parental participation in the program increased the use of reappraisal and emotion coaching strategies; and (c) children's ER mediated the intervention's effect on social competence, whereas parental coaching and parental ER mediated SEP effects on children's ER. This study's findings suggest that the SEP may be an effective universal intervention for promoting preschoolers' social-emotional competence and may provide emerging evidence to support the program's hypothesized mechanisms of change.

Environmental cleaning to prevent hospital-acquired infections on non-intensive care units: a pragmatic, single-centre, cluster randomized controlled, crossover trial comparing soap-based, disinfection and probiotic cleaning. EClinicalMedicine 2023; 59:101958. [PMID: 37089619 PMCID: PMC10113752 DOI: 10.1016/j.eclinm.2023.101958] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 03/22/2023] [Accepted: 03/22/2023] [Indexed: 04/25/2023] Open
Abstract
Background The impact of environmental hygiene on the occurrence of hospital-acquired infections (HAIs) remains a subject of debate. We determined the effect of three different surface-cleaning strategies on the incidence of HAIs. Methods Between June 2017 and August 2018 we conducted a pragmatic, cluster-randomized controlled crossover trial at 18 non-ICU wards in the university hospital of Berlin, Germany. Surfaces in patient rooms on the study wards were routinely cleaned using one of three agents: Soap-based (reference), disinfectant and probiotic. Each strategy was used on each ward for four consecutive months (4m-4m-4m). There was a one-month wash-in period at the beginning of the study and after each change in strategy. The order of strategies used was randomized for each ward. Primary outcome was the incidence of HAIs. The trial was registered with the German Clinical Trials Register, DRKS00012675. Findings 13,896 admitted patients met the inclusion criteria, including 4708 in the soap-based (reference) arm, 4535 in the disinfectant arm and 4653 in the probiotic arm. In the reference group, the incidence density of HAIs was 2.31 per 1000 exposure days. The incidence density was similar in the disinfectant arm 2.21 cases per 1000 exposure days (IRR 0.95; 95% CI 0.69-1.31; p = 0.953) and the probiotic arm 2.21 cases per 1000 exposure days (IRR 0.96; 95% CI 0.69-1.32; p = 0.955). Interpretation In non-ICU wards, routine surface disinfection proved not superior to soap-based or probiotic cleaning in terms of HAI prevention. Thus, probiotic cleaning could be an interesting alternative, especially in terms of environmental protection. Funding Federal Ministry of Education and Research of Germany (03Z0818C).

BISCIT: Biliary interventions in critically ill patients with secondary sclerosing cholangitis-a study protocol for a multicenter, randomized, controlled parallel group trial. Trials 2023; 24:247. [PMID: 37004078 PMCID: PMC10067228 DOI: 10.1186/s13063-023-07260-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Accepted: 03/17/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Progress of cholangitis to cholangiosepsis is a frequent observation in patients with secondary sclerosing cholangitis in critically ill patients (SSC-CIP). Adequate biliary drainage may reduce episodes of cholangiosepsis and therefore stabilize liver function and improve survival. The primary objective of the BISCIT study is to demonstrate that scheduled biliary interventions will reduce incidence of cholangiosepsis, liver transplantation, or death in patients with SSC-CIP. METHODS A total of 104 patients will be randomized at ten study sites. Patients with SSC-CIP, confirmed by endoscopic retrograde cholangiography (ERC), will be randomized 1:1 either in the intervention group which will be treated with scheduled biliary interventions (i.e., therapeutic ERC) every 8 weeks for 6 months or in the control group which will receive standard of care. The randomization will be stratified by center. The composite primary efficacy endpoint is defined as (1) occurrence of death, (2) necessity of liver transplantation, or (3) occurrence of cholangiosepsis within 6 months following randomization. DISCUSSION Prospective evaluation of endoscopic treatment procedures is urgently needed to establish an evidence-based therapeutic treatment algorithm in SSC-CIP. A positive trial result could change the current standard of care for patients with SSC-CIP. The results of this study will be disseminated through presentations at international congresses, workshops, and peer-reviewed publications. TRIAL REGISTRATION The trial was registered at ClinicalTrials.gov (NCT05396755, date of registration: May 31, 2022, last update: May 31, 2022).

Abstract
OBJECTIVES Chronic ankle instability (CAI) is associated with decreased neural excitability that negatively impacts function. This study assessed a 2-week neuromuscular electrical stimulation (NMES) or transcutaneous electrical nerve stimulation (TENS) intervention over the ankle pronators on neural excitability, performance, and patient-reported function in patients with CAI. STUDY DESIGN Randomized controlled trial. PARTICIPANTS Twenty participants with CAI completed the study. MAIN OUTCOME MEASURES Participants were assessed for reflexive and corticospinal excitability to the ankle muscles, dynamic balance, side-hop test performance and patient-reported outcomes at baseline, post-intervention (2-weeks), and retention (4-weeks). Between baseline and post-intervention, participants reported for 5 sessions where they received either sub-noxious NMES (n = 11) or sensory-level TENS (n = 9) over the ankle pronators. RESULTS Improved reflexive excitability to the ankle pronators was observed in TENS at post-intervention (p = 0.030) and retention (p = 0.029). Cortical excitability to the dorsiflexors increased in TENS at post-intervention (p = 0.017), but not at retention (p = 0.511). No significant changes were found for other neural measures, balance ability, hopping, or patient-reported function (p > 0.050). CONCLUSIONS Our results suggest TENS modified neural excitability; however, these changes were not enough to impact clinical function. While TENS may be capable of neuromodulation, it may require rehabilitative exercise to generate lasting changes. NCT04322409. LEVEL OF EVIDENCE Level 2.

CANNA-TICS: Efficacy and safety of oral treatment with nabiximols in adults with chronic tic disorders - Results of a prospective, multicenter, randomized, double-blind, placebo controlled, phase IIIb superiority study. Psychiatry Res 2023; 323:115135.

Abstract
Preliminary data suggest that cannabis-based medicines might be a promising new treatment for patients with Tourette syndrome (TS)/chronic tic disorders (CTD) resulting in an improvement of tics, comorbidities, and quality of life. This randomized, multicenter, placebo-controlled, phase IIIb study aimed to examine efficacy and safety of the cannabis extract nabiximols in adults with TS/CTD (n = 97, randomized 2:1 to nabiximols:placebo). The primary efficacy endpoint was defined as a tic reduction of ≥ 25% according to the Total Tic Score of the Yale Global Tic Severity Scale after 13 weeks of treatment. Although a much larger number of patients in the nabiximols compared to the placebo group (14/64 (21·9%) vs. 3/33 (9·1%)) met the responder criterion, superiority of nabiximols could formally not be demonstrated. In secondary analyses, substantial trends for improvements of tics, depression, and quality of life were observed. Additionally exploratory subgroup analyses revealed an improvement of tics in particular in males, patients with more severe tics, and patients with comorbid attention deficit/hyperactivity disorder suggesting that these subgroups may benefit better from treatment with cannabis-based medication. There were no relevant safety issues. Our data further support the role of cannabinoids in the treatment of patients with chronic tic disorders.

[PMID: 36814350 PMCID: PMC9946867 DOI: 10.1186/s13063-023-07155-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Accepted: 02/10/2023] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND Adults with intellectual disabilities have a higher prevalence of unhealthy eating habits, stress, low levels of mobility, and comparable drug consumption as the general population. Consequently, they suffer from several chronic diseases earlier and more often, but there are fewer prevention and health promotion services including this population. The goal of this study is to determine if an advanced practice nursing approach in the community with home visits is an effective way to improve the health status of adults with intellectual disabilities. METHODS We will conduct a randomized-controlled trial with waiting list design in Hamburg, Germany. Inclusion criteria are diagnosis ICD F70-F79 and exclusion criteria are care level > 3 according to the German Social Code XI or being at the end-of-life. Participants will be block randomized. The intervention consists of advanced practice nurses performing case management, social space analysis, prevention planning, and counseling through four outreach home visits on nutrition, mobility, addiction, and stress. Comparison is usual care. The primary outcome is health status (WHODAS) after 12 months. Secondary outcomes are health-related quality of life (EQ-5D) and resilience (RS-11) after 6 and 12 months. The calculated sample size is 256 with an estimated dropout of 30%. Raters and analysts will be blinded. Analysis will be performed using ANCOVAs. DISCUSSION By providing case management and utilizing their nursing expertise, advanced practice nurses will provide valuable input and guidance on prevention and health promotion for people with intellectual disabilities. They will close the gap between health and social care, which is prominent in Germany, through cooperation between the existing care sectors. The findings will be disseminated in peer-reviewed journals and presented at national and international conferences.

An experimental approach to training interoceptive sensitivity: study protocol for a pilot randomized controlled trial. Nutr J 2022; 21:74. [PMID: 36529744 PMCID: PMC9761996 DOI: 10.1186/s12937-022-00827-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Accepted: 11/10/2022] [Indexed: 12/23/2022] Open
Abstract
BACKGROUND Eating in absence of hunger is quite common and often associated with an increased energy intake co-existent with a poorer food choice. Intuitive eating (IE), i.e., eating in accordance with internal hunger and satiety cues, may protect from overeating. IE, however, requires accurate perception and processing of one's own bodily signals, also referred to as interoceptive sensitivity. Training interoceptive sensitivity might therefore be an effective method to promote IE and prevent overeating. As most studies on eating behavior are conducted in younger adults and close social relationships influence health-related behavior, this study focuses on middle-aged and older couples. METHODS The present pilot randomized intervention study aims at investigating the feasibility and effectiveness of a 21-day mindfulness-based training program designed to increase interoceptive sensitivity. A total of N = 60 couples participating in the NutriAct Family Study, aged 50-80 years, will be recruited. This randomized-controlled intervention study comprises three measurement points (pre-intervention, post-intervention, 4-week follow-up) and a 21-day training that consists of daily mindfulness-based guided audio exercises (e.g., body scan). A three-arm intervention study design is applied to compare two intervention groups (training together as a couple vs. training alone) with a control group (no training). Each measurement point includes the assessment of self-reported and objective indicators of interoceptive sensitivity (primary outcome), self-reported indicators of intuitive and maladaptive eating (secondary outcomes), and additional variables. A training evaluation applying focus group discussions will be conducted to assess participants' overall acceptance of the training and its feasibility. DISCUSSION By investigating the feasibility and effectiveness of a mindfulness-based training program to increase interoceptive sensitivity, the present study will contribute to a deeper understanding of how to promote healthy eating in older age.

Enhancing children's cognitive function and achievement through carotenoid consumption: The Integrated Childhood Ocular Nutrition Study (iCONS) protocol. Contemp Clin Trials 2022; 122:106964. [PMID: 36252934 PMCID: PMC10150405 DOI: 10.1016/j.cct.2022.106964] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 10/05/2022] [Accepted: 10/11/2022] [Indexed: 01/27/2023]
Abstract
Lutein and zeaxanthin (L + Z) are carotenoids that accumulate in neural tissue and potentially confer benefits to cognition. Whereas cross-sectional studies have revealed positive associations between macular carotenoids (MC) and cognition, no studies have investigated whether L + Z supplementation impacts MC and cognition in childhood. Accordingly, the Integrated Childhood Ocular Nutrition Study aims to investigate the impact of L + Z supplementation over 9-months on academic abilities, attentional control, memory, and MC among preadolescent children. Children 8-10 years (N = 288) will enroll in a 9-month double-blind, placebo-controlled, randomized trial. The study is registered and approved as a clinical trial on the U.S. National Library of Medicine http://ClinicalTrials.gov registry (NCT05177679). Participants will be randomized into an active (10 mg lutein+2 mg zeaxanthin) or waitlist placebo-controlled group. Primary outcomes include hippocampal-dependent memory, attentional inhibition, and academic achievement using a spatial reconstruction task, an Eriksen flanker task, and the Kaufman Test of Academic and Educational Achievement 3rd edition, respectively. Secondary outcomes include event-related brain potentials of attentional resource allocation and information processing speed (i.e., P3/P300 amplitude and latency) recorded during the flanker task. Macular pigment optical density (MPOD) will be assessed using heterochromatic flicker photometry. Cognitive assessments will be completed prior to and after completion of the supplementation period. MPOD will be quantified prior to, at the mid-point of (4-5 months), and after (9 months) the supplementation period. It is hypothesized that L + Z supplementation will improve cognition and academic achievement. Further, benefits for cognition and achievement are anticipated to be mediated by increases in MC among treatment group participants.

The impact of a specialist home-visiting intervention on the language outcomes of young mothers and their children: a pragmatic randomised controlled trial. BMC Psychol 2022; 10:224. [PMID: 36151554 PMCID: PMC9508755 DOI: 10.1186/s40359-022-00926-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Accepted: 09/05/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Young mothers are more likely to provide a suboptimal early language environment for their children who in turn show impairments in their language development, yet few studies have used observational methods to assess the effectiveness of home-visiting programmes in improving the language outcomes of young mothers and their children. The Family Nurse Partnership (FNP) is a licensed home-visiting intervention developed in the USA and introduced into practice in England. The intervention involves up to 64 structured home visits from early pregnancy until the child's second birthday by specially recruited and trained Family Nurses. We assessed the effectiveness of FNP in improving the language outcomes of first-time teenage mothers and their infants. METHOD We conducted a pragmatic, non-blinded, randomised controlled trial to test whether the FNP programme improved mothers' and children's language production at 24 months postpartum. Eligible participants were nulliparous, aged 19 years or younger, and were recruited at less than 25 weeks' gestation from community midwifery settings (Country). Pregnant young mothers were randomly assigned to FNP plus usual care (n = 243) or usual care alone (n = 233). At 24 months postpartum, mother-child dyads were observed during a standardised free-play task with their first-born child and features of their language production was coded. Data was analysed using multi-level modelling; linear or poisson/negative binomial regression models were used as appropriate. RESULTS A small effect of FNP on mothers' productive language was detected, where mothers in the FNP group demonstrated higher mean length of utterances than mothers who received usual care alone, mean difference (adjusted by minimisation variables and by site, linear regression) = 0.10, p < .05, 95% CI (0.004-0.20), d = .18. No differences were detected between groups regarding other characteristics of maternal language or children's language outcomes. CONCLUSION This observational study conducted within the context of a randomised-controlled trial suggests that the FNP home-visiting programme may have a small, but potentially important impact on young mothers' speech to their toddlers. Exploratory analyses identified family environment, maternal, and child related predictors of the language outcomes of young mothers and their offspring. Trial registration This trial is registered with ISRCTN, number ISRCTN23019866, 20/04/2009.

Randomized controlled phase 2 trial of hydroxychloroquine in childhood interstitial lung disease. Orphanet J Rare Dis 2022; 17:289. [PMID: 35871071 PMCID: PMC9308121 DOI: 10.1186/s13023-022-02399-2] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2022] [Accepted: 06/11/2022] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND No results of controlled trials are available for any of the few treatments offered to children with interstitial lung diseases (chILD). We evaluated hydroxychloroquine (HCQ) in a phase 2, prospective, multicentre, 1:1-randomized, double-blind, placebo-controlled, parallel-group/crossover trial. HCQ (START arm) or placebo were given for 4 weeks. Then all subjects received HCQ for another 4 weeks. In the STOP arm subjects already taking HCQ were randomized to 12 weeks of HCQ or placebo (= withdrawal of HCQ). Then all subjects stopped treatment and were observed for another 12 weeks. RESULTS 26 subjects were included in the START arm, 9 in the STOP arm, of these four subjects participated in both arms. The primary endpoint, presence or absence of a response to treatment, assessed as oxygenation (calculated from a change in transcutaneous O2-saturation of ≥ 5%, respiratory rate ≥ 20% or level of respiratory support), did not differ between placebo and HCQ groups. Secondary endpoints including change of O2-saturation ≥ 3%, health related quality of life, pulmonary function and 6-min-walk-test distance, were not different between groups. Finally combining all placebo and all HCQ treatment periods did not identify significant treatment effects. Overall effect sizes were small. HCQ was well tolerated, adverse events were not different between placebo and HCQ. CONCLUSIONS Acknowledging important shortcomings of the study, including a small study population, the treatment duration, lack of outcomes like lung function testing below age of 6 years, the small effect size of HCQ treatment observed requires careful reassessments of prescriptions in everyday practice (EudraCT-Nr.: 2013-003714-40, www.clinicaltrialsregister.eu , registered 02.07.2013). Registration The study was registered on 2 July 2013 (Eudra-CT Number: 2013-003714-40), whereas the approval by BfArM was received 24.11.2014, followed by the approval by the lead EC of the University Hospital Munich on 20.01.2015. At clinicaltrials.gov the trial was additionally registered on November 8, 2015 (NCT02615938).

Green-lipped (greenshell™) mussel (Perna canaliculus) extract supplementation in treatment of osteoarthritis: a systematic review. Inflammopharmacology 2021; 29:925-938. [PMID: 33738701 PMCID: PMC8298224 DOI: 10.1007/s10787-021-00801-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Accepted: 03/06/2021] [Indexed: 11/23/2022]
Abstract
OBJECTIVES Intervention studies using New Zealand green-lipped or greenshell™ mussel (GSM) (Perna canaliculus) extract in osteoarthritis (OA) patients have shown effective pain relief. This systematic review summarises the efficacy of GSM extracts in the treatment of OA. METHODS A literature search of the three databases EMBASE, MEDLINE, and Scopus was performed to identify relevant articles published up to March 2020. Inclusion criteria were clinical trials published in English measuring the effect of supplementation of whole or a lipid extract from GSM on pain and mobility outcomes in OA patients. RESULTS A total of nine clinical trials were included in systematic review, from which five studies were considered appropriate for inclusion in a forest plot. Pooled results showed that GSM extracts (lipid extract or whole powder) provide moderate and clinically significant treatment effects on a visual analogue scale (VAS) pain score (effect size: - 0.46; 95% CI - 0.82 to - 0.10; p = 0.01). The whole GSM extract improved gastrointestinal symptoms in OA patients taking anti-inflammatory medications. The GSM extract was considered to be generally well tolerated in most of the studies. CONCLUSION The overall analysis showed that GSM provided moderate and clinically meaningful treatment effects on OA pain. However, the current evidence is limited by the number and quality of studies, and further larger and high-quality studies are needed to confirm the effectiveness and to identify the optimal GSM format. Nevertheless, it is worth considering using GSM extracts especially for patients seeking alternative pain relief treatments with fewer side effects compared to conventional treatment.

How do care providers evaluate collaboration? - qualitative process evaluation of a cluster-randomized controlled trial of collaborative and stepped care for patients with mental disorders. BMC Psychiatry 2021; 21:296. [PMID: 34098913 PMCID: PMC8184353 DOI: 10.1186/s12888-021-03274-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2020] [Accepted: 05/06/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Collaborative and stepped care (CSC) models are recommended for mental disorders. Their successful implementation depends on effective collaboration between involved care providers from primary and specialist care. To gain insights into the collaboration experiences of care providers in CSC against the backdrop of usual mental health care, a qualitative process evaluation was realized as part of a cluster-randomized controlled trial (COMET) of a collaborative and stepped care model in Hamburg (Germany). METHODS Semi-structured interviews were conducted with N = 24 care providers from primary and specialist care (outpatient psychotherapists and psychiatrists, inpatient/ day clinic mental health providers) within and outside of COMET at the trial's beginning and 12 months later. Interviews were analyzed applying a qualitative structuring content analysis approach, combining deductive and inductive category development. RESULTS Usual mental health care was considered deficient in resources, with collaboration being scarce and mainly taking place in small informal networks. Within the COMET trial, quicker referral paths were welcomed, as were quarterly COMET network meetings which provided room for exchange and fostered mutual understanding. Yet, also in COMET, collaboration remained difficult due to communication problems, the unfavorable regional distribution of the COMET care providers and interprofessional discrepancies regarding each profession's role, competencies and mutual esteem. Ideas for improvement included more localized networks, the inclusion of further professions and the overall amelioration of mental health care regarding resources and remuneration, especially for collaborative activities. CONCLUSIONS The process evaluation of the COMET trial revealed the benefits of creating room for interprofessional encounter to foster collaborative care. Despite the benefits of faster patient referrals, the COMET network did not fulfill all care providers' prior expectations. A focus should be set on interprofessional competencies, mutual perception and role clarification, as these have been revealed as significant barriers to collaboration within CSC models such as COMET. TRIAL REGISTRATION The COMET trial (Collaborative and Stepped Care in Mental Health by Overcoming Treatment Sector Barriers) has been registered on July 24, 2017 under the trial registration number NCT03226743 .

Abstract
This study examined differential responses among partners who participated in a RCT designed to compare two social cognitive theory interventions, one designed for patients only (P-only) and one for patients and their intimate partners (P + P). The interventions were delivered following the patient receiving an initial ICD implant. Partner health outcomes were examined longitudinally from baseline at hospital discharge to 3, 6, and 12 months. Outcomes included 6 measures: partner physical and mental health status (Short-Form-36 PCS and MCS), depression (Patient Health Questionnaire-9), anxiety (State-Trait Anxiety Inventory), caregiver burden (Oberst Caregiver Burden Scale), and self-efficacy in ICD management (Sudden Cardiac Arrest Self-efficacy scale). Growth mixture and mixed effect modeling were used to identify and compare trajectories of 6 health outcomes within the P-only and P + P arms of the study. Partners (n = 301) were on average 62 years old, female (74.1%) and Caucasian (83.4%), with few co-morbidities (mean Charlson Co-morbidity index, 0.72 ± 1.1). Two types of profiles were observed for P-only and P + P, one profile where patterns of health outcomes were generally better across 12 months and one with outcome patterns that were generally worse across time. For PCS, no significant partner differences were observed between P-only or P + P in either the better (p = 0.067) or the worse (p = 0.129) profile types. Compared to P-only, partners in the worse profile improved significantly over 12 months in MCS (p = 0.006), caregiver burden P + P (p = 0.004) and self-efficacy P + P (p = 0.041). Compared to P-only, P + P partners in the low anxiety profile improved significantly (p = 0.001) at 3 months. Partners with more psychosocial distress at hospital discharge benefited most from the P + P intervention. Among partners with generally low levels of anxiety, those in the P + P intervention compared to P-only showed greater improvement in anxiety over 12 months.

Abstract
PURPOSE Coffee is an important source of bioactive compounds, including caffeine, trigonelline, and phenolic compounds. Several studies have highlighted the preventive effects of coffee consumption on major cardiometabolic (CM) diseases, but the impact of different coffee dosages on markers of CM risk in a real-life setting has not been fully understood. This study aimed to investigate the effect of coffee and cocoa-based confectionery containing coffee consumption on several CM risk factors in healthy subjects. METHODS In a three-arm, crossover, randomized trial, 21 volunteers were assigned to consume in a random order for 1 month: 1 cup of espresso coffee/day, 3 cups of espresso coffee/day, and 1 cup of espresso coffee plus 2 cocoa-based products containing coffee, twice per day. At the last day of each treatment, blood samples were collected and used for the analysis of inflammatory markers, trimethylamine N-oxide, nitric oxide, blood lipids, and markers of glucose/insulin metabolism. Moreover, anthropometric parameters and blood pressure were measured. Finally, food consumption during the interventions was monitored. RESULTS After 1 month, energy intake did not change among treatments, while significant differences were observed in the intake of saturated fatty acids, sugars, and total carbohydrates. No significant effect on CM markers was observed following neither the consumption of different coffee dosages nor after cocoa-based products containing coffee. CONCLUSIONS The daily consumption of common dosages of coffee and its substitution with cocoa-based products containing coffee showed no effect on CM risk factors in healthy subjects.

Abstract
Objective: Several studies have shown that closed-loop automated insulin delivery (the artificial pancreas) improves glucose control compared with sensor-augmented pump therapy. We aimed to confirm these findings using our automated insulin delivery system based on the iPancreas platform. Research Design and Methods: We conducted a two-center, randomized crossover trial comparing automated insulin delivery with sensor-augmented pump therapy in 36 adults with type 1 diabetes. Each intervention lasted 12 days in outpatient free-living conditions with no remote monitoring. The automated insulin delivery system used a model predictive control algorithm that was a less aggressive version of our earlier dosing algorithm to emphasize safety. The primary outcome was time in the range 3.9-10.0 mmol/L. Results: The automated insulin delivery system was operational 90.2% of the time. Compared with the sensor-augmented pump therapy, automated insulin delivery increased time in range (3.9-10.0 mmol/L) from 61% (interquartile range 53-74) to 69% (60-73; P = 0.006) and increased time in tight target range (3.9-7.8 mmol/L) from 37% (30-49) to 45% (35-51; P = 0.011). Automated insulin delivery also reduced time spent below 3.9 and 3.3 mmol/L from 3.5% (0.8-5.4) to 1.6% (1.1-2.7; P = 0.0021) and from 0.9% (0.2-2.1) to 0.5% (0.2-1.1; P = 0.0122), respectively. Time spent below 2.8 mmol/L was 0.2% (0.0-0.6) with sensor-augmented pump therapy and 0.1% (0.0-0.4; P = 0.155) with automated insulin delivery. Conclusions: Our study confirms findings that automated insulin delivery improves glucose control compared with sensor-augmented pump therapy. ClinicalTrials.gov no. NCT02846831.

[PMID: 32895879 PMCID: PMC7581585 DOI: 10.1007/s10198-020-01230-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/17/2020] [Accepted: 08/26/2020] [Indexed: 06/11/2023]
Abstract
BACKGROUND Person-centred care has been shown to be cost-effective compared to usual care for several diseases, including acute coronary syndrome, in a short-term time perspective (< 2 years). The cost-effectiveness of person-centred care in a longer time perspective is largely unknown. OBJECTIVES To estimate the mid-term cost-effectiveness of person-centred care compared to usual care for patients (< 65) with acute coronary syndrome, using a 2-year and a 5-year time perspective. METHODS The mid-term cost-effectiveness of person-centred care compared to usual care was estimated by projecting the outcomes observed in a randomized-controlled trial together with data from health registers and data from the scientific literature, 3 years beyond the 2-year follow-up, using the developed simulation model. Probabilistic sensitivity analyses were performed using Monte Carlo simulation. RESULTS Person-centred care entails lower costs and improved effectiveness as compared to usual care, for a 2-year time and a 5-year perspective. Monte Carlo simulations suggest that the likelihoods of the person-centred care being cost-effective compared to usual care were between 80 and 99% and between 75 and 90% for a 2-year and a 5-year time perspective (using a 500,000 SEK/QALY willingness-to-pay threshold). CONCLUSIONS Person-centred care was less costly and more effective compared to usual care in a 2-year and a 5-year time perspective for patients with acute coronary syndrome under the age of 65.

Abstract
Depending on the scientific hypothesis to be addressed, randomized-controlled trials (RCT) are accordingly designed. RCTs that aim to determine whether a novel, experimental therapeutic intervention (either a drug or a treatment) is superior to a placebo or control intervention, are called superiority trials. Less common are the non-inferiority RCTs, designed to assess whether a new intervention is not unacceptably worse than an already existing reference intervention. An equivalence RCT is designed to investigate whether a novel treatment is equivalently effective to another, already existing, control intervention. In equivalence and non-inferiority RCTs, the efficacy of the reference intervention (active comparator) is already established, and therefore, an untreated control group would not be ethical. In this review, using a series of examples derived from equivalence and non-inferiority/superiority RCTs, we describe the main differences and methodological aspects among these three different types of RCTs.

Chinese herbal medicine combined with entecavir to reduce the off-therapy recurrence risk in HBeAg-positive chronic hepatitis B patients: a multicener, double-blind, randomized controlled trial in China. Trials 2020; 21:708.

Abstract
Background Nucleos(t)ide analogues (NAs) are the first-line option against chronic hepatitis B (CHB). NAs produce potent suppression of viral replication with a small chance of HBsAg seroclearance and a high risk of virological relapse after discontinuation. The combined therapy of NAs plus traditional Chinese medicine (TCM) is widely accepted and has been recognized as a prospective alternative approach in China. Based on preliminary works, this study was designed to observe the therapeutic effect of TCM plus entecavir (ETV) against HBeAg-positive chronic hepatitis B with respect to reducing the recurrence risk after NA withdrawal. Methods/design The study is a nationwide, multicenter, double-blind, randomized, placebo-controlled trial with a duration of 120 weeks. A total of 18 hospitals and 490 eligible Chinese HBeAg-positive CHB patients will be enrolled and randomly allocated into the experimental group and control group in a 1:1 ratio. Patients in the experimental group will be prescribed TCM formulae (Tiaogan-BuXu-Jiedu granules) plus ETV 0.5 mg per day for consolidation therapy for 96 weeks. Patients in the control group will be prescribed TCM granule placebo plus ETV 0.5 mg per day for the same course. After consolidation therapy, all patients will discontinue their trial drugs and be closely monitored over the next 24 weeks. Once clinical recurrence (CR) occurs, ETV treatment will be restarted. The primary outcome is the cumulative rate of CR at the end of this trial. Conclusion This study is the first of its kind to observe therapeutic effects with respect to reducing recurrence after NA withdrawals after unified integrative consolidation therapy in the CHB population.

Effects of mechanical vibrations on maxillary canine retraction and perceived pain: a pilot, single-center, randomized-controlled clinical trial. Odontology 2020; 108:321-330. [PMID: 31912371 DOI: 10.1007/s10266-019-00480-0] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Accepted: 09/26/2019] [Indexed: 01/13/2023]
Abstract
The aim of this study was to investigate the effect of mechanical vibratory stimulation on maxillary canine retraction and pain perception in adolescents undergoing full-fixed orthodontic treatment with extraction. A pilot randomized-controlled clinical trial was conducted in one university orthodontic clinic. Twenty-one healthy adolescents who underwent full-fixed orthodontic treatment with maxillary first-premolar extraction were recruited. Subjects were randomly assigned to the experimental group (N = 10) that used a mechanical vibration device (AcceleDent Aura, OrthoAccel Technologies, Inc.) or the control group (N = 11) that did not receive a vibration device. The evaluation timepoints were T0 = day of initial canine retraction; T1 = 4 weeks post-initiation; T2 = 8 weeks post-initiation; and T3 = 12 weeks post-initiation. Three-dimensional palatal landmark superimpositions were made to assess amount of tooth movement (mm) at each visit, monthly rate of tooth movement (mm), and perceived pain levels (VAS scores). The total amount of tooth movement was observed in the control versus experimental groups, respectively, as 1.12 ± 0.22 mm versus 1.39 ± 0.36 mm at 4 weeks (p = 0.058), 2.59 ± 0.37 mm versus 2.49 ± 0.76 mm at 8 weeks (p = 0.702), and 3.54 ± 0.23 mm versus 3.37 ± 1.37 mm at 12 weeks (p = 0.716). The rate of tooth movement was 1.21 ± 0.32 mm/month in the control and 1.12 ± 0.20 mm/month in the experimental groups, which was not statistically significant at any of the timepoints and neither was the level of pain. This study found no statistically significant differences in canine retraction and pain perception between the experimental and control groups. We propose that further optimization of accelerated tooth movement with mechanical vibration devices is necessary.

An Overview of Systematic Reviews of Randomized-Controlled Trials for Preventing Necrotizing Enterocolitis in Preterm Infants. Neonatology 2020; 117:46-56. [PMID: 31838477 DOI: 10.1159/000504371] [Citation(s) in RCA: 21] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Accepted: 10/27/2019] [Indexed: 11/19/2022]
Abstract
Necrotizing enterocolitis (NEC) remains a major cause for neonatal mortality and morbidity in preterm infants. The purpose of this review was to summarize evidence from systematic reviews of randomized-controlled trials (RCTs) regarding antenatal and postnatal interventions for preventing NEC. PubMed, EMBASE, the Cochrane Library Databases, Database of Abstracts of Reviews of Effects, and Campbell Library were searched for meta-analyses in which NEC was reported as an outcome after antenatal or postnatal strategies. The AMSTAR instrument was used to evaluate quality of included reviews. Grading of Recommendations, Assessment, Development and Evaluation assessment was used to evaluate certainty of evidence. We identified 98 meta-analyses of RCTs. The quality of included reviews was adequate, whereas the certainty of evidence was moderate to very low. Moderate certainty evidence showed a reduction in NEC following administration of a combination of species of probiotics, probiotics (any), antenatal corticosteroids in pregnant women at risk of preterm birth, and ibuprofen versus indomethacin for treatment of patent ductus arteriosus (PDA). For surgical NEC, moderate certainty evidence showed an increased risk with lower (85-89%) oxygen saturation target levels, compared with higher (91-95%) oxygen saturation target levels. In conclusion, decreased risk of NEC is observed with probiotics, antenatal corticosteroids for women at risk of preterm birth, and ibuprofen versus indomethacin for treatment of PDA. Targeting lower oxygen saturations may increase the risk of surgical NEC, compared to targeting higher saturations.

Abstract
Increasing evidence suggests that the function of the GABAergic system is abnormally low in autism spectrum disorder (ASD). Baclofen, which functions as a selective agonist for GABAB receptors, does appear promising for the treatment of ASD. We conducted a 10-week randomized-controlled study aimed at evaluating the potential of baclofen as an adjuvant therapy to enhance the effect of risperidone in children with ASD. Sixty-four children (3-12 years) with moderate-to-severe irritability symptoms of ASD were included. We used the Aberrant Behavior Checklist-Community Edition (ABC-C) for the outcome measures on each of the follow-up visits (weeks 0, 5, and 10). Analysis of the combined data revealed significant improvement for all the ABC subscales (irritability: F = 51.644, df = 1.66, p < 0.001, lethargy: F = 39.734, df = 1.38, p < 0.001, stereotypic behavior: F = 25.495, df = 1.56, p < 0.001, hyperactivity: F = 54.135, df = 1.35, p < 0.001, and inappropriate speech: F = 19.277, df = 1.47, p = 0.004). Combined treatment with baclofen and risperidone exerted a greater effect on improvement of hyperactivity symptoms at both midpoint [Cohen's d, 95% confidence interval (CI) = - 3.14, - 5.56 to - 0.72] and endpoint (d, 95% CI = - 4.45, - 8.74 to - 0.16) when compared with treatment with placebo plus risperidone. The two treatments achieved comparable results for other outcome measures. Our data support safety and efficacy of baclofen as an adjuvant to risperidone for improvement of hyperactivity symptoms in children with ASD.

Abstract
BACKGROUND AND AIMS Systemic reviews and meta-analyses suggest hyperuricemia is a cardiovascular risk factor. The effects of xanthine oxidase inhibitors on cardiac outcomes remain unclear. We assessed the effects of febuxostat and allopurinol on mortality and adverse reactions in adult patients with hyperuricemia. METHODS AND RESULTS PubMed and EMBASE were searched to retrieve randomized controlled trials of febuxostat and allopurinol from January 2005 to July 2018. The meta-analysis consisted of 13 randomized controlled trials with a combined sample size of 13,539 patients. Febuxostat vs. allopurinol was not associated with an increased risk of cardiac-related mortality in the overall population (OR: 0.72, 95% CI: 0.24-2.13, P = 0.55). Regarding adverse skin reactions, the patients receiving febuxostat had significantly fewer adverse skin reactions than those receiving allopurinol treatment (OR: 0.50, 95% CI: 0.30-085, P = 0.01). Compared with allopurinol, febuxostat was associated with an improved safety outcome of cardiac-related mortality and adverse skin reactions (OR: 0.72, 95% CI: 0.55-0.96, P = 0.02). The net clinical outcome, composite of incident gout and the safety outcome, was not different significantly in the patients receiving febuxostat or allopurinol (OR: 1.04, 95% CI: 0.76-0.1.42, P = 0.79). In sensitivity analyses, a borderline significance was found in the patients randomized to febuxostat vs. allopurinol regarding cardiac-related mortality (OR: 1.29, 95% CI: 1.00-1.67, P = 0.05) after the CARES study was included. CONCLUSION Febuxostat vs. allopurinol was associated with the improved safety outcome and have comparable mortality and net clinical outcome in patients with hyperuricemia.

Abstract
PURPOSE The meta-analysis aimed to evaluate the effect of gonadotrophin-releasing hormone agonist (GnRH-a) addition for luteal support on pregnancy outcome in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. METHODS Meta-analysis. RESULTS A total of 3,584 cycles were identified from 13 randomized controlled trials. The cumulative analysis showed that GnRH-a addition for luteal supports significantly improved live birth rate (relative risk [RR] = 1.52; 95% CI 1.20-1.94; p = 0.0006), the clinical pregnancy rate (RR 1.21; 95% CI 1.11-1.33; p < 0.0001), ongoing pregnancy rate (RR 1.18; 95% CI 1.06-1.32; p = 0.004), pregnancy rate (RR 1.36; 95% CI 1.01-1.82; p = 0.04), implantation rate (RR 1.44; 95% CI 1.17-1.77; p = 0.0007), and multiple pregnancy rate (RR 1.40; 95% CI 1.04-1.88; p = 0.03) in comparison with control, but not for the incidence of ovarian hyperstimulation syndrome (RR 0.96; 95% CI 0.32-2.89; p = 0.94). We also found that GnRH-a addition for luteal support had a tendency to decrease the abortion rate (RR 0.72; 95% CI 0.56-0.93; p = 0.01). CONCLUSIONS Overall, the current meta-analysis showed a substantial efficacy of GnRH-a addition for luteal support on pregnancy outcomes in women undergoing IVF/ICSI and support the use of GnRH-a in luteal phase to improve the success of IVF/ICSI.

Abstract
BACKGROUND Phenolisation of Sacrococcygeal pilonidal sinus disease (SPSD) seems to have advantages over radical excision; however, a randomized-controlled trial (RCT) comparing both techniques is lacking. The aim of our study was to compare sinus pit excision and phenolisation of the sinus tract with radical excision in SPSD in terms of return to normal daily activities. METHODS This study was a single-center RCT. Fifty patients who presented with primary SPSD were randomized to phenolisation and 50 patients to excision. The primary endpoint was time to return to normal daily activities. Secondary endpoints were quality of life, complaints related to SPSD, surgical site infection, and wound epithelialization. Patients were treated in a 1-day surgery setting. Complaints related to SPSD were evaluated and symptoms were scored by the participants on a 6-point scale before surgery, and patients kept a diary for 2 weeks on complaints related to the surgical treatment (the same scoring system as preoperatively) and pain, evaluated with a VAS. Quality of life (QoL) was measured preoperatively with a VAS and the Short Form-36 Health Survey (SF-36). At 2, 6, and 12 weeks after surgery, patients were evaluated using a questionnaire containing the following items: patients' satisfaction (disease, compared with preoperatively, scored as cured, improved, unchanged or worsened), five complaints related to the surgical treatment (the same scoring system as preoperatively and in the diary), QoL (VAS and SF-36), and return to normal daily activities. The wound was assessed 2, 6, and 12 weeks postoperatively by one of the investigators (EF or NS), using an assessment form RESULTS: The mean time to return to normal daily activities was significantly shorter after phenolisation (5.2 ± SD 6.6 days vs. 14.5 ± 25.0 days, p = 0.023). 2 weeks after surgery, all patients in the phenolisation group and 85.4% of patients in the excision group returned to normal daily activities (p = 0.026). Pain was significantly lower after phenolisation at 2 weeks postoperatively (0.8 ± 1.0 vs. 1.6 ± 1.3, p = 0.003). Surgical site infection occurred significantly more often after radical excision (n = 10, 21.7% vs. n = 2, 4.0%, p = 0.020). At 6 and 12 weeks, complete wound epithelialization was more frequently achieved after phenolisation (69.0% vs. 37.0%, p = 0.003 and 81.0% vs. 60.9%, p = 0.039, respectively). CONCLUSIONS Pit excision with phenolisation of SPSD resulted in a quicker return to normal daily activities, less pain, and quicker wound epithelialization compared to radical excision. Surgeons should consider phenolisation in patients with primary SPSD.

Efficacy of high-frequency repetitive transcranial magnetic stimulation in schizophrenia patients with treatment-resistant negative symptoms treated with clozapine. Schizophr Res 2019; 208:370-376. [PMID: 30704862 DOI: 10.1016/j.schres.2019.01.021] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Revised: 01/17/2019] [Accepted: 01/19/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND Repetitive transcranial magnetic stimulation (rTMS) is a promising augmentation treatment for schizophrenia, however there are few controlled studies of rTMS augmentation of clozapine. METHODS Using data from the 'rTMS for the Treatment of Negative Symptoms in Schizophrenia' (RESIS) trial we examined the impact of rTMS on PANSS total, general, positive and negative symptoms among participants on clozapine. rTMS was applied to the left dorsolateral prefrontal cortex (DLPFC) for five treatment sessions/week for 3-weeks as augmentation for patients with a predominant negative syndrome of schizophrenia, as rated on PANSS. RESULTS 26 participants from the RESIS trial were on clozapine, receiving active (N=12) or sham (N=14) rTMS treatment. In our Linear Mixed Model (LMM) analysis, time×group interactions were significant in the PANSS positive subscale (p=0.003) (not being the corresponding behavioral output for DLPFC stimulation), the PANSS general subscale (p<0.001), the PANSS total scale (p=0.015), but not the PANSS negative subscale (p=0.301) (primary endpoint of the RESIS trial), when all PANSS measurements from screening to day 105 were included. Descriptive data suggests that in the active group the improvement was more pronounced compared to the sham rTMS group. CONCLUSIONS In this largest available clozapine cohort, active rTMS may be more effective than sham rTMS when added to clozapine for positive and total psychotic symptoms. These findings should be interpreted with caution given this is a secondary analysis with a limited number of participants.

Abstract
School-based social and emotional learning programs aim to provide students with the skills they need to deal with life challenges, thereby enhancing their social and emotional wellbeing, academic outcomes, and reducing their risk of mental health difficulties. While there is a robust evidence base on the effectiveness of these programs originating from the US, there is a relative paucity of research on how these programs impact young people in other county contexts, especially for older adolescents and those at higher risk. This study sets out to address this research gap by evaluating the effectiveness of a social emotional learning program designed for older adolescents in Ireland, the MindOut program. MindOut is a universal school-based social and emotional learning program designed for older adolescents in Ireland which was developed based on a common elements approach underpinned by CASEL's framework. Employing a cluster randomized-controlled trial, data on social and emotional skills, academic performance and mental health outcomes were collected from students (n = 497; 51.1% female) ages 15-18 years in 32 disadvantaged schools. There were significant improvements in intervention students' social and emotional skills including, reduced suppression of emotions (p = 0.035), use of more positive coping strategies [reduced avoidance coping p = < 0.001) and increased social support coping p = 0.044)]. Improvements in mental health and wellbeing were also found with significantly reduced levels of stress (p = 0.017) and depressive symptoms (p = 0.030) as well as reduced anxiety scores for females students (p = 0.044). These short-term evaluation findings support the positive impact of school-based social and emotional learning programs, such as MindOut, when designed to be both age and culturally appropriate and delivered to older adolescents in disadvantaged schools.

Abstract
Background Volunteering could be a win-win opportunity for older adults: Links between volunteering and societal improvements as well as older adults’ own health and longevity are found in several observational studies. RCTs to increase volunteering in older adults are however sparse, leaving the question of causality unanswered. This study protocol describes a theory-based social-cognitive intervention with multiple behavior change techniques to increase volunteering among community-dwelling older adults in Hong Kong. Methods In a parallel group, two-arm, randomized controlled trial, an initial N = 360 are assigned to receive either the volunteering intervention or the active control intervention (parallel content targeting physical activity). The primarily outcome measure is self-reported volunteering minutes per month at baseline, six weeks, three months and six months after the intervention. Participants in the treatment group are expected to increase their weekly volunteering minutes over time as compared to participants in the control group. Possible active ingredients of the intervention as well as mental and physical health outcomes of increased volunteering are investigated by means of mediation analyses. Discussion Like many industrialized nations, Hong Kong faces a rapid demographic change. An effective psychological intervention to encourage retirees to engage in formal volunteering would alleviate some of the societal challenges a growing proportion of older adults entails.

Abstract
Therapeutic games represent a promising solution for addressing emotional difficulties in youths. The aim of the present study was to investigate the effectiveness of the REThink game, in helping children and adolescents, to develop psychological resilience. Therefore, 165 children aged between 10 and 16 years were randomly assigned in one of the three groups: 54 participants in the REThink condition, 55 participants in the Rational Emotive Behavior Education condition, and 56 participants in the waitlist condition. Results indicated that the REThink intervention had a significant impact on emotional symptoms (a moderate-effect size, d = 0.46) and on depressive mood (a large-effect size, d = 0.84). Furthermore, REThink had a significant impact on children's ability to regulate their emotions, with a significant effect on emotional awareness (d = 0.64), and on the ability for emotional control (d = 0.69). In conclusion, the implications of the REThink game are discussed in relationship with resiliency building programs designed for youths. TRIAL REGISTRATION: ClinicalTrials.gov NCT03308981.

Abstract
PURPOSE This study was performed to determine whether periarticular injection performed in the early stage of total knee arthroplasty (TKA) could provide a better postoperative pain relief than periarticular injection performed in the late stage of TKA. The hypothesis was based on the concept that analgesic intervention before the onset of noxious stimuli would be associated with less postoperative pain. METHODS A total of 105 participants were randomly assigned to receive superficial injection just prior to arthrotomy (early stage periarticular injection group) or superficial injection after implanting the prosthesis (late-stage periarticular injection group) in patients undergoing unilateral TKA with 1:1 treatment allocation. In both groups, deep injection was performed according to the same schedule (just prior to implanting prosthesis). The solution consisted of 300 mg of ropivacaine, 8 mg of morphine, 40 mg of methylprednisolone, 50 mg of ketoprofen, and 0.3 mg of epinephrine mixed with normal saline to a final volume of 60 mL. All surgeries were managed under general anesthesia without any regional blocks. Registry-specified primary outcome was postoperative pain score at rest measured at the recovery room using a 100-mm visual analog scale (VAS). The VAS score was compared between two groups and assessed to reach the reported threshold values for the minimal clinically important difference (MCID) of 10 mm for the postoperative VAS score. RESULTS The VAS score at the recovery room was significantly lower in the early stage periarticular injection group than the late-stage periarticular injection group (23 ± 25 mm versus 39 ± 34 mm, respectively; 95% confidence interval 4-28 mm; p = 0.0078). The mean difference in the primary outcome fulfilled the MCID value. CONCLUSIONS Bringing forward the timing of periarticular injection may provide significant and clinically meaningful improvement in pain following TKA under general anesthesia. LEVEL OF EVIDENCE I.

Informant-related effects of neurofeedback and cognitive training in children with ADHD including a waiting control phase: a randomized-controlled trial.

Abstract
There is controversy regarding the clinical efficacy of neurofeedback (NF) and computerized cognitive training (CogT) as treatments for ADHD. Meta-analyses claim that probably blinded teachers observe smaller effects than parents, because they are less biased. We investigated informant-specific effects by manipulating the involvement of informants, by controlling for waiting time effects, and by adding a blinded outcome measure. Seventy-seven children with ADHD were randomly allocated to slow cortical potential NF or to individualized CogT (of attention, working memory or inhibition). The training was conducted in schools (NF: n = 19, CogT: n = 19) or in outpatient clinics (NF: n = 19, CogT: n = 20). Three assessments were scheduled: baseline, followed by a waiting period, pre-training, and post-training. Multivariate Analyses of Variance were conducted to assess parent- and teacher-rated changes in ADHD symptoms and executive functions (EF), and changes according to standardized classroom observations. Both treatments resulted in significant improvements according to informants, with larger effects for parents (ADHD symptoms: parent η p2 = .32; teacher η p2 = .10), and according to observations (η p2 = .19). The setting had no effect on outcome. Considerable waiting time effects were revealed for ADHD symptom ratings by both informants, for EF ratings only by teachers. Changed classroom behavior was uncorrelated with teacher-rated changes. Overall, the results do not support the notion that teachers are more objective while being as sensitive to change as parents. The three sources seem to contribute differential and mostly unrelated pieces of information to the evaluation of treatments.

PURPOSE Bipolar endoscopic enucleation of the prostate (BEEP) was recommended by the 2016 EAU guidelines as the first choice of surgical treatment in men with a substantially enlarged prostate and moderate-to-severe lower urinary tract symptoms. The main aim of this study was to compare a modified diode laser enucleation of the prostate (DiLEP) to BEEP. METHODS A total of 114 patients with prostate (20-160 mL) were randomized 1:1 into either DiLEP or BEEP in a dual-centre, non-inferiority-design randomized-controlled trial. The primary outcomes included Qmax and IPSS at 12 months. Non-inferiority was evaluated by comparing the two-sided 95% CI for the mean differences of Qmax and IPSS. Secondary endpoints included other perioperative parameters, postoperative micturition variables, and complication rate. RESULTS A total of 111 patients (97%) had completed the intent-to-treat analysis, The results showed that DiLEP was comparable to BEEP regarding Qmax (28.0 ± 7.0 vs. 28.1 ± 7.2 mL/s) and IPSS (3.0 ± 2.2 vs. 2.9 ± 2.6) at 12 months, the non-inferiority was met for both Qmax and IPSS. There were also no significant difference between two groups regarding tissue removal rate (71.8 vs. 73.8%), hemoglobin decrease (0.33 ± 0.66 vs. 0.36 ± 0.75 g/dL), sodium decrease (1.0 ± 2.7 vs. 0.3 ± 2.9 mmol/L), and Clavien III complications (5.3 vs. 1.8%) at 12 months. CONCLUSIONS This DiLEP is an anatomical endoscopic enucleation technique for the treatment of benign prostatic hyperplasia, it is non-inferior to BEEP regarding Qmax and IPSS at 12 months postoperatively.

The 2017 Dutch Physical Activity Guidelines. Int J Behav Nutr Phys Act 2018; 15:58. [PMID: 29940977 PMCID: PMC6016137 DOI: 10.1186/s12966-018-0661-9] [Citation(s) in RCA: 103] [Impact Index Per Article: 17.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Accepted: 03/12/2018] [Indexed: 01/19/2023] Open
Abstract
Background The objective of this study was to derive evidence-based physical activity guidelines for the general Dutch population. Methods Two systematic reviews were conducted of English language meta-analyses in PubMed summarizing separately randomized controlled trials and prospective cohort studies on the relation between physical activity and sedentary behaviour on the one hand and the risk of all-cause mortality and incidence of 15 major chronic diseases and conditions on the other hand. Other outcome measures were risk factors for cardiovascular disease and type 2 diabetes, physical functioning, and fitness. On the basis of these reviews, an expert committee derived physical activity guidelines. In deriving the guidelines, the committee first selected only experimental and observational prospective findings with a strong level of evidence and then integrated both lines of evidence. Results The evidence found for beneficial effects on a large number of the outcome measures was sufficiently strong to draw up guidelines to increase physical activity and reduce sedentary behaviour, respectively. At the same time, the current evidence did not provide a sufficient basis for quantifying how much physical activity is minimally needed to achieve beneficial health effects, or at what amount sedentary behaviour becomes detrimental. A general tenet was that at every level of current activity, further increases in physical activity provide additional health benefits, with relatively larger effects among those who are currently not active or active only at light intensity. Three specific guidelines on (1) moderate- and vigorous-intensity physical activity, (2) bone- and muscle-strengthening activities, and (3) sedentary behaviour were formulated separately for adults and children. Conclusions There is an unabated need for evidence-based physical activity guidelines that can guide public health policies. Research in which physical activity is measured both objectively (quantity) and subjectively (type and quality) is needed to provide better estimates of the type and actual amount of physical activity required for health.

Efficacy of high-frequency repetitive transcranial magnetic stimulation on PANSS factors in schizophrenia with predominant negative symptoms - Results from an exploratory re-analysis. Psychiatry Res 2018; 263:22-29. [PMID: 29482042 DOI: 10.1016/j.psychres.2018.02.030] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2017] [Revised: 02/13/2018] [Accepted: 02/14/2018] [Indexed: 10/18/2022]
Abstract
Repetitive transcranial magnetic stimulation (rTMS) applied to the left frontal lobe is discussed to be a promising add-on treatment for negative symptoms in schizophrenia. The Positive and Negative Syndrome Scale (PANSS) has been used as outcome parameter in several previous rTMS trials, but studies focusing on PANSS factor analyses are lacking. For this purpose, we used the available PANSS data of the 'rTMS for the Treatment of Negative Symptoms in Schizophrenia' (RESIS) trial to calculate different literature-based PANSS factors and to re-evaluate the impact of rTMS on negative symptoms in this trial. In an exploratory re-analysis of published data from the RESIS study (Wobrock et al. 2015), we tested the impact of rTMS applied to the left dorsolateral prefrontal cortex on two PANSS factors for negative symptoms in psychotic disorders as well as on a PANSS five-factor consensus model intending to show that active rTMS treatment improves PANSS negative symptom subscores. In accordance to the original analysis, all PANSS factors showed an improvement over time in the active and, to a considerable extent, also in the sham rTMS group. However, comparing the data before and directly after the rTMS intervention, the PANSS excitement factor improved in the active rTMS group significantly more than in the sham group, but this finding did not persist if follow-up data were taken into account. These additional analyses extend the previously reported RESIS trial results showing unspecific improvements in the PANSS positive subscale in the active rTMS group. Our PANSS factor-based approach to investigate the impact of prefrontal rTMS on different negative symptom domains confirmed no overall beneficial effect of the active compared to sham rTMS.

Abstract
BACKGROUND Physical activity confers numerous health benefits, yet few adults meet recommended physical activity guidelines. PURPOSE The impact of brief messages providing descriptive and injunctive social norm feedback on physical activity was tested in this conceptual pilot study. METHODS Young adults (N = 111) were randomly assigned to one of three conditions: descriptive norm feedback, descriptive-plus-injunctive norm feedback, or no social feedback (control condition). Participants used pedometers for eight weekdays and recorded their step counts each evening. The descriptive norm group received feedback about the average number of steps taken by group members the previous day. The descriptive-plus-injunctive norm group received feedback about the group average, as well as a sad face if the participant was below the average or a happy face if the participant was above the average. The control group received no feedback throughout the study. RESULTS By days 7 and 8, the descriptive-plus-injunctive norm group reported significantly more steps relative to the control group, whereas the descriptive norm group showed a trend toward higher step counts relative to the control group. These effects did not differ for participants above versus below the group average at baseline. CONCLUSION The combined use of descriptive and injunctive social norms increased physical activity over a short period. This simple feedback strategy has potential for achieving wide reach and dissemination on its own or combined with more comprehensive interventions. This initial evidence can guide larger trials of longer duration. TRIAL REGISTRATION NUMBER The trial was registered with the ClinicalTrials.gov database (NCT02710201).

Abstract
BACKGROUND The increasing prevalence of childhood obesity is - amongst other factors - due to changed leisure time habits with decreased physical activity and increased media consumption. However, electronic media such as tablets and smartphones might also provide a novel intervention approach to prevent obesity in childhood and adolescence. OBJECTIVES A summary of interventions applying electronic media to prevent childhood obesity is provided to investigate short term effects as well as long term results of these interventions. METHODS A systematic literature search was performed in PubMed/Web of Science to identify randomized and/or controlled studies that have investigated the efficacy of electronic media for obesity prevention below the age of 18. RESULTS A total of 909 studies were identified, and 88 studies were included in the analysis. Active video games did increase physical activity compared to inactive games when applied within a peer group. Interventions via telephone had positive effects on certain lifestyle-relevant behaviours. Interventions via mobile were shown to decrease dropout rates by sending regular SMS messages. To date, interventions via smartphones are scarce for adolescents; however, they might improve cardiorespiratory fitness. The results from internet-based interventions showed a trend towards positive effects on lifestyle-relevant behaviors. The combination of different electronic media did not show superior results compared to interventions with only one medium. Interventions via TV, DVD or video-based interventions may increase physical activity when offered as an incentive, however, effects on weight status were not observed. DISCUSSION Children and adolescents currently grow up in a technology- and media-rich society with computers, tablets, smartphones, etc. used daily. Thus, interventions applying electronic media to prevent childhood obesity are contemporary. Available studies applying electronic media are however heterogeneous in terms of applied medium and duration. Positive effects on body composition were not observed, but only on certain lifestyle-relevant behaviours. In addition, these effects could only be seen in the short term. Follow-up data are currently scarce.

Abstract
Vitamin D insufficiency is widespread in HIV-infected patients. HIV and/or antiretroviral therapy (ART), particularly efavirenz (EFV), may interfere with vitamin D metabolism. However, few data from randomized, controlled trials exist. Here, we investigate changes in vitamin D metabolites and binding protein (VDBP) after 6 months of supplementation in a randomized, active-control, double-blind trial investigating 2 different monthly cholecalciferol (vitamin D3) doses [60,000 (medium) or 120,000 (high) IU/month] vs. a control arm of 18,000 IU/month in 8-25year old HIV-infected youth on ART with HIV-1 RNA <1000 copies/mL and baseline 25-hydroxycholecalciferol (25(OH)D3) ≤30ng/mL. A matched healthy uninfected group was enrolled in a similar parallel study for comparison. Changes after 6 months were analyzed as intent-to-treat within/between groups [control group (low dose) vs. combined supplementation doses (medium+high)]. At 6 months, 55% vs. 82% of subjects in control and supplementation groups, respectively, reached 25(OH)D3 ≥30ng/mL (P=0.01) with no difference between medium and high doses (both 82% ≥30ng/mL). There were few differences for those on EFV vs. no-EFV, except serum VDBP decreased in EFV-treated subjects (both within- and between-groups P≤0.01). There were no significant differences between the HIV-infected vs. healthy uninfected groups. The major finding of the present study is that cholecalciferol supplementation (60,000 or 120,000 IU/month) effectively raises serum 25(OH)D3 in the majority of HIV-infected subjects, regardless of EFV use. Notably, response to supplementation was similar to that of uninfected subjects.

Chinese herbal medicine adjunct therapy in patients with acute relapse of multiple sclerosis: A systematic review and meta-analysis. Complement Ther Med 2017; 31:71-81. [PMID: 28434474 DOI: 10.1016/j.ctim.2017.02.004] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2016] [Revised: 12/29/2016] [Accepted: 02/19/2017] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Many patients with multiple sclerosis (MS) resort to complementary and alternative medicine, which is used in 33%-80% of MS patients in the developed country. The purpose of this study is to assess the efficacy and safety of Chinese herbal medicine (CHM) as an adjunct therapy of patients with acute relapse of MS. METHODS Six databases were searched for randomized-controlled trial of CHM for acute relapse of MS. The risk of bias was assessed by using the twelve criteria recommended by the Cochrane Back Review Group. The primary outcome measures of interest are the Expanded Disability Status Score, annual relapse frequency, annual relapse rate, and annual relapse interval. The secondary outcome measures are the clinical efficacy rate and adverse events. The selection criteria of high-frequency herbs for MS are those with cumulative frequency over 50%. We analyzed the data using Review Manager (version 5.3). RESULTS A total of 1100 participants were included in the 20 studies from 2004 to 2015. The number of risk of bias which met the criteria varied from 5/12 to 7/12. The top 5 most frequently used herbs are ordinally Radix Angelicae Sinensis, Radix Glycyrrhizae, Radix Paeoniae Rubra, Radix Rehmanniae Preparata, and Bombyx Batryticatus. The meta-analysis showed a significant effect of CHM for improving Expanded Disability Status Score (P<0.01), annual relapse frequency (P<0.01) and the total clinical efficacy rate (P<0.01) compared with western conventional treatment. In analysis of annual relapse rate and annual relapse interval, there was a significant difference between CHMs and western conventional treatment (P<0.01). Adverse effects were monitored in 6 studies, and were well tolerated in all MS patients. CONCLUSIONS The available evidence from present study supported but limited to recommend the routine use of CHM adjuvant therapy for MS because of the poor methodological quality and clinical heterogeneity. However, we identified an area that is worthy of further study. Furthermore, we selected high frequent use of CHMs as a promising candidate for further clinical application and MS trials. Further rigorous randomized-controlled trials are needed.

Abstract
Although bystander programs to prevent relationship and sexual violence have been evaluated with college students, few evaluations have been conducted with high school students. This study evaluated the effectiveness of TakeCARE, a brief video bystander program designed to promote helpful bystander behavior in situations involving relationship violence among high school students. Students (N = 1295; 52.5% female; 72.3% Hispanic) reported their bystander behavior at a baseline assessment. Classrooms (N = 66) were randomized to view TakeCARE or to a control condition, and high school counselors administered the video in the classrooms assigned to view TakeCARE. Students again reported their bystander behavior at a follow-up assessment approximately 3 months afterward. Results indicate that students who viewed TakeCARE reported more helpful bystander behavior at the follow-up assessment than students in the control condition. Results of exploratory analyses of the likelihood of encountering and intervening upon specific situations calling for bystander behavior are also reported. TakeCARE is efficacious when implemented in an urban high school by high school counselors.

Time-to-event versus ten-year-absolute-risk in cardiovascular risk prevention - does it make a difference? Results from the Optimizing-Risk-Communication (OptRisk) randomized-controlled trial. BMC Med Inform Decis Mak 2016; 16:152. [PMID: 27899103 PMCID: PMC5129612 DOI: 10.1186/s12911-016-0393-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2016] [Accepted: 11/22/2016] [Indexed: 12/02/2022] Open
Abstract
Background The concept of shared-decision-making is a well-established approach to increase the participation of patients in medical decisions. Using lifetime risk or time-to-event (TTE) formats has been increasingly suggested as they might have advantages, e.g. in younger patients, to better show consequences of unhealthy behaviour. In this study, the most-popular ten-year risk illustration in the decision-aid-software arribaTM (emoticons), is compared within a randomised trial to a new-developed TTE illustration, which is based on a Markov model. Methods Thirty-two General Practitioners (GPs) took part in the study. A total of 304 patients were recruited and counseled by their GPs with arribaTM, and randomized to either the emoticons or the TTE illustration, followed by a patient questionnaire to figure out the degree of shared-decision-making (PEF-FB9, German questionnaire to measure the participation in the shared decision-making process, primary outcome), as well as the decisional conflict, perceived risk, accessibility and the degree of information, which are all secondary outcomes. Results Regarding our primary outcome PEF-FB9 the new TTE illustration is not inferior compared to the well-established emoticons taking the whole study population into account. Furthermore, the non-inferiority of the innovative TTE could be confirmed for all secondary outcome variables. The explorative analysis indicates even advantages in younger patients (below 46 years of age). Conclusion The TTE format seems to be as useful as the well-established emoticons. For certain patient populations, especially younger patients, the TTE may be even superior to demonstrate a cardiovascular risk at early stages. Our results suggest that time-to-event illustrations should be considered for current decision support tools covering cardiovascular prevention.

Abstract
Generalized anxiety disorder (GAD) is characterized by emotion regulation difficulties, which are associated with abnormalities in neural circuits encompassing fronto-limbic regions including the dorsolateral prefrontal cortex (DLPFC). The aim of this study was to determine whether DLPFC neuromodulation improves emotion regulation in patients with GAD. This is a secondary analysis from a randomized-controlled trial comparing 30 sessions of low-frequency right-sided active (n=13) versus sham (n=12, sham coil) repetitive transcranial magnetic stimulation (rTMS) at the right DLPFC in patients with GAD. Results indicated statistically significant improvements in self-reported emotion regulation difficulties at posttreatment and 3-month follow-up in the active group only. Improvements were found primarily in the domains of goal-directed behaviors and impulse control and were significantly associated with a global clinician rating of improvement. These preliminary results support rTMS as a treatment for GAD and suggest improved emotion regulation as a possible mechanism of change.

Abstract
INTRODUCTION The long-term success of non-surgical weight loss treatment in adults with obesity is limited by substantial relapse, and only a few evidence-based weight loss maintenance treatments exist. This clinical trial investigates the feasibility and efficacy of a social facilitation maintenance programme for weight loss maintenance, tailored to meet the needs of obese adults who have undergone a lifestyle weight loss intervention. METHODS AND ANALYSIS In a single-centre, open feasibility trial, 72 adults currently or previously obese or overweight who have undergone a lifestyle weight loss intervention are centrally randomised to 4 months of social facilitation maintenance treatment or treatment as a usual control condition. In 16 outpatient group sessions, the social facilitation maintenance treatment, based on a socioecological model and on evidence supporting social facilitation as a key process in maintaining weight loss, focuses on promoting interpersonal relationships to build up a healthy lifestyle for long-term weight loss maintenance. Primary outcome is the amount of weight regain at 6-month follow-up, compared with pre-treatment weight, derived from measured body weight. Secondary outcomes address feasibility, including recruitment, attrition, assessment non-completion, compliance and patients' programme evaluation; and in comparison with pre-weight loss maintenance, social and interpersonal functioning, eating behaviour and physical activity, psychological and physical symptoms, body composition and risk of comorbidity, and quality of life at post-treatment and follow-up assessments. ETHICS AND DISSEMINATION The study was approved by the Ethical Committee at the University of Leipzig (165-13-15072013). The study results will be disseminated through peer-reviewed publications.

Abstract
Background Green tea is a beverage with potential effects on cognitive dysfunction, as indicated by results of experimental studies. However, its effects in humans, especially at real-world (typical) consumption levels, are unclear. Methods A double-blind, randomized controlled study was conducted to assess the effects of green tea consumption on cognitive dysfunction (Mini-Mental State Examination Japanese version (MMSE-J) score <28) in Japan. Participants were randomly allocated to the green tea or placebo group, and consumed either 2 g/day of green tea powder (containing 220.2 mg of catechins) or placebo powder (containing 0.0 mg of catechins), respectively, for 12 months. Cognitive function assessments were performed every 3 months using the MMSE-J and laboratory tests. Results Thirty-three nursing home residents with cognitive dysfunction were enrolled (four men, 29 women; mean age ± SD, 84.8 ± 9.3; mean MMSE-J score ± SD, 15.8 ± 5.4), of whom 27 completed the study. Changes of MMSE-J score after 1 year of green tea consumption were not significantly different compared with that of the placebo group (−0.61 [−2.97, 1.74], least square mean (LSM) difference [95 % CI]; P = 0.59). However, levels of malondialdehyde-modified low-density lipoprotein (U/L), a marker of oxidative stress, was significantly lower in the green tea group (−22.93 [−44.13, −1.73], LSM difference [95 % CI]; P = 0.04). Conclusions Our results suggest that 12 months green tea consumption may not significantly affect cognitive function assessed by MMSE-J, but prevent an increase of oxidative stress in the elderly population. Additional long-term controlled studies are needed to clarify the effects.
