Background: Decisions regarding maintenance therapy in patients with multiple myeloma should be based on both treatment efficacy and health-related quality of life (HRQL) consequences. In the CARFI trial, patients with first relapse of multiple myeloma underwent salvage autologous stem cell transplantation (salvage ASCT) before randomization to carfilzomib-dexamethasone maintenance therapy (Kd) or observation. The primary clinical endpoint was time to progression, which was extended by 8 months by Kd. The aim of this paper is to present the all HRQL endpoints of the CARFI trial including the HRQL effect of Kd maintenance therapy relative to observation. The primary HRQL endpoint was assessed by EORTC QLQ-C30 Summary score (QLQ-C30-sum) at 8 months follow-up. A key secondary HRQL endpoint was quality-adjusted progression-free-survival (QAPFS). Methods: HRQL was assessed with EORTC QLQ-C30, EORTC QLQ-MY20 and FACT/GOG-Ntx at randomization and every second month during follow-up. HRQL data were analyzed with linear mixed effect models until 8 months follow-up. QAPFS per individual was calculated by multiplying progression-free survival (PFS) by two quality-adjustment metrics, the QLQ-C30-sum and EORTC Quality of Life Utility Measure-Core 10 dimensions (QLU-C10D). The QAPFS per treatment group was estimated with the Kaplan-Meier method. P < 0.05 was used for statistical significance, and a between-group minimal important difference of 10 points was interpreted as clinically relevant for the QLQ-C30-sum. Results: 168 patients were randomized. HRQL questionnaire compliance was 93%. For the QLQ-C30-sum, the difference of 4.62 points (95% confidence interval (CI) -8.9: -0.4, p = 0.032) was not clinically relevant. PFS was 19.3 months for the Kd maintenance group and 16.8 months for the observation group; difference = 2.5 months (95% CI 0.5; 4.5). QAPFS based on the QLQ-C30-sum for the Kd maintenance group was 18.0 months (95% CI 16.4; 19.6) and for the observation group 15.0 months (95% CI 13.5; 16.5); difference = 3.0 months (95% CI 0.8–5.3). QAPFS based on the QLU-C10D for the Kd maintenance group was 17.5 months (95% CI 15.9; 19.2) and 14.0 months (95% CI 12.4; 15.5) for the observation group; difference = 3.5 months (95% CI 1.1–5.9). Conclusions: Kd maintenance therapy after salvage ASCT did not adversely affect overall HRQL, but adjustment for HRQL reduced the PFS compared to unadjusted PFS. PFS of maintenance therapy should be quality-adjusted to balance the benefits and HRQL impact. [ABSTRACT FROM AUTHOR]

Background: Various physical fitness qualities such as muscle strength, speed and endurance are related to soccer performance. Accordingly, the combination of strength and endurance training (i.e., concurrent training [CT]) is an often-encountered training regimen in soccer. Less is known about the effects of CT sequencing on performance in young soccer players. The aim of this study was to assess the sequencing effects of strength and intermittent endurance training applied within the same training session (intrasession) on measures of physical fitness and soccer performance in young soccer players. Methods: Fifty male adolescent soccer players volunteered to participate in this study which was conducted in the Netherlands in 2019. Players were randomly assigned to a strength-endurance (SE) or an endurance-strength (ES) group in matched pairs based on their countermovement jump (CMJ) performance at baseline. Both groups completed a 12-weeks in-season training program with two weekly CT sessions. Training sessions consisted of 15 min plyometric exercises and 15 min soccer-specific intermittent endurance training. Both groups performed the same training volumes and the only difference between the groups was the CT intrasession sequencing scheme (SE vs. ES). Pre and post intervention, proxies of muscle power (CMJ, squat jump [SJ]), linear sprint speed (30-m sprint test), agility (Illinois test with / without ball), and soccer performance (ball kicking velocity) were tested. Results: Data from 38 players aged 14.8 ± 1.0 years (body height 172.9 ± 8.1 cm, body mass: 57.0 ± 7.2 kg, soccer experience: 8.8 ± 2.8 years, age from peak-height-velocity [PHV]: +1.2 ± 1.0 years) were included. Significant main time effects were found for CMJ (p = 0.002, d = 0.55), SJ (p = 0.004, d = 0.51), the Illinois agility test with ball (p = 0.016, d = 0.51), and ball kicking velocity (p = 0.016, d = 0.51). Significant group-by-time interactions were observed for 30-m linear sprint speed (p < 0.001, d = 0.76) with ES showing greater improvements (p = 0.006, d = 0.85, Δ-5%). Conclusions: Both CT-sequencing types improved performance in the tests administered. The intrasession CT sequencing (SE vs. ES) appears not to have a major impact on physical fitness adaptations, except for linear sprint speed which was in favor of ES. Key points: • This study examined the effects of intrasession concurrent training. Findings showed that strength-endurance and endurance-strength sequencing resulted in similar changes in most measures of physical fitness in adolescent male soccer players. • If the goal is to improve linear sprint speed, endurance-strength sequencing appears to be better suited. • More research is needed to acquire further knowledge on concurrent training and effects of different types of sequencing schemes (e.g., training day, microcycle) as well as the strength training (e.g., power training) and endurance training type (e.g., high intensity interval training).

6–11-year-old children provide a critical window for physical activity (PA) interventions. The Virtual Fitness Buddy ecosystem is a precision health PA intervention for children integrating mixed reality technology to connect people and devices. A cluster randomized, controlled trial was conducted across 19 afterschool sites over two 6-month cohorts to test its efficacy in increasing PA and decreasing sedentary behavior. In the treatment group, a custom virtual dog via a mixed reality kiosk helped children set PA goals while sharing progress with parents to receive feedback and support. Children in the control group set PA goals using a computer without support from the virtual dog or parents. 303 children had 8+ hours of PA data on at least one day of each of the 3 intervention time intervals. Conversion of sedentary time was primarily to light-intensity PA and was strongest for children with low baseline moderate-to-vigorous PA than children above 45 min of baseline moderate-to-vigorous PA. Findings suggest that the VFB ecosystem can promote sustainable PA in children and may be rapidly diffused for widespread public health impact. [ABSTRACT FROM AUTHOR]

Purpose: Patient-reported outcome measures (PROMs) are designed to assess patients' perceived health states or health-related quality of life. However, PROMs are susceptible to missing data, which can affect the validity of conclusions from randomised controlled trials (RCTs). This review aims to assess current practice in the handling, analysis and reporting of missing PROMs outcome data in RCTs compared to contemporary methodology and guidance. Methods: This structured review of the literature includes RCTs with a minimum of 50 participants per arm. Studies using the EQ-5D-3L, EORTC QLQ-C30, SF-12 and SF-36 were included if published in 2013; those using the less commonly implemented HUI, OHS, OKS and PDQ were included if published between 2009 and 2013. Results: The review included 237 records (4-76 per relevant PROM). Complete case analysis and single imputation were commonly used in 33 and 15 % of publications, respectively. Multiple imputation was reported for 9 % of the PROMs reviewed. The majority of publications (93 %) failed to describe the assumed missing data mechanism, while low numbers of papers reported methods to minimise missing data (23 %), performed sensitivity analyses (22 %) or discussed the potential influence of missing data on results (16 %). Conclusions: Considerable discrepancy exists between approved methodology and current practice in handling, analysis and reporting of missing PROMs outcome data in RCTs. Greater awareness is needed for the potential biases introduced by inappropriate handling of missing data, as well as the importance of sensitivity analysis and clear reporting to enable appropriate assessments of treatment effects and conclusions from RCTs.

Background: Frailty is associated with poor outcomes among older adults with hypertension and complicates its pharmacological management. Here, we assessed whether 12-weeks of instructor-guided, group Tai Chi (TC) practice improved frailty relative to Healthy Aging Practice-centered Education (HAP-E) classes in older adults with hypertension. Methods: Secondary analysis of a randomized controlled trial in San Diego County, USA, of 167 community-dwelling individuals aged ≥ 60 yrs (70% female; 72.1 ± 7.5 yrs), defined as non-frail (66%) or frail (34%) based on 53-item deficit accumulation frailty index (FI). Linear mixed-effects models were used to assess pre-to-post intervention differences in FI and logistic regression to explore differential odds of clinically meaningful FI change. Results: One hundred thirty-one participants completed post-intervention assessments. Frailty decreased pre-to-post intervention in the TC (ΔFI = − 0.016, d = − 0.39, − 0.75 to − 0.03), but not the HAP-E arm (ΔFI = − 0.009, d = − 0.13, − 0.52–0.27), despite no significant group differences between the TC and HAP-E arms (d = − 0.11, − 0.46–0.23). Furthermore, greater odds of improved FI were observed for frail participants in the TC (OR = 3.84, 1.14–14.9), but not the HAP-E (OR = 1.34, 0.39–4.56) arm. Subgroup analysis indicated treatment effects in TC were attributed to frail participants (frail: ΔFI = − 0.035, d = − 0.68, -1.26 to − 0.08; non-frail: ΔFI = − 0.005, d = − 0.19, − 0.59–0.22), which was not the case in the HAP-E arm (frail: ΔFI = − 0.017, d = − 0.23, − 0.81–0.35; non-frail: ΔFI = − 0.003, d = − 0.07, − 0.47–0.33). Frail participants were no more likely to drop-out of the study than non-frail (71% vs. 69% retained). Conclusions: Twelve weeks of twice-weekly guided TC practice was well-tolerated, associated with decreases in frailty, and increased odds of clinically meaningful FI improvement at post-intervention.

Purpose: Adherence to the Mediterranean diet is associated with beneficial health effects, including gastrointestinal disorders. Preclinical studies suggest that omega-3 polyunsaturated fatty acids (n-3 PUFAs), found in Mediterranean foods like nuts and fish, improve intestinal barrier integrity. Here, we assessed possible effects of n-3 PUFAs on barrier integrity in a randomized controlled trial. Methods: We studied 68 women from the open-label LIBRE trial (clinicaltrials.gov: NCT02087592) who followed either a Mediterranean diet (intervention group, IG) or a standard diet (control group, CG). Study visits comprised baseline, month 3, and month 12. Barrier integrity was assessed by plasma lipopolysaccharide binding protein (LBP) and fecal zonulin; fatty acids by gas chromatography with mass spectrometry. Median and interquartile ranges are shown. Results: Adherence to the Mediterranean diet increased the proportion of the n-3 docosahexaenoic acid (DHA) (IG + 1.5% [0.9;2.5, p < 0.001]/ + 0.3% [− 0.1;0.9, p < 0.050] after 3/12 months; CG + 0.9% [0.5;1.6, p < 0.001]/ ± 0%) and decreased plasma LBP (IG − 0.3 µg/ml [− 0.6;0.1, p < 0.010]/ − 0.3 µg/ml [− 1.1; − 0.1, p < 0.001]; CG − 0.2 µg/ml [− 0.8; − 0.1, p < 0.001]/ ± 0 µg/ml) and fecal zonulin levels (IG − 76 ng/mg [− 164; − 12, p < 0.010]/ − 74 ng/mg [− 197;15, p < 0.001]; CG − 59 ng/mg [− 186;15, p < 0.050]/ + 10 ng/mg [− 117;24, p > 0.050]). Plasma DHA and LBP (R2: 0.14–0.42; all p < 0.070), as well as plasma DHA and fecal zonulin (R2: 0.18–0.48; all p < 0.050) were found to be inversely associated in bi- and multivariate analyses. Further multivariate analyses showed that the effect of DHA on barrier integrity was less pronounced than the effect of fecal short-chain fatty acids on barrier integrity. Conclusions: Our data show that n-3 PUFAs can improve intestinal barrier integrity. Trial registration number: The trial was registered prospectively at ClinicalTrials.gov (reference: NCT02087592).

Integration of vocational rehabilitation and mental healthcare has shown some effect on work participation at 1-year follow-up after sick leave with depression and anxiety. We aimed to study the effect on work and health outcomes at 2-year follow-up, why we performed a randomized trial was conducted to study the effectiveness of integrated intervention (INT) compared to service as usual (SAU) and best practice mental healthcare (MHC). We included 631 participants, and at 24-month follow-up, we detected no differences in effect between INT and SAU. Compared to MHC, INT showed faster return-to-work (RTW) rates (p = 0.044) and a higher number of weeks in work (p = 0.024). No symptom differences were observed between the groups at 24 months. In conclusion, compared to SAU, INT was associated with a slightly higher work rate reaching borderline statistical significance at 12-month follow-up and lower stress levels at 6-month follow-up. The disappearance of relative effect between 12 and 24 months may be explained by the fact that the intervention lasted less than 12 months or by delayed spontaneous remission in the SAU group after 12 months. Despite the lack of effect at long-term follow-up, INT still performed slightly better than SAU overall. Moderate implementation difficulties, may partly explain the absence of the hypothesized effect. Integrated intervention, as implemented in this trial, showed some positive effects on mid-term vocational status and short-term stress symptom levels. However, these effects were not sustained beyond the duration of the intervention. [ABSTRACT FROM AUTHOR]

Background: Casein protein ingestion prior to sleep has been shown to increase myofibrillar protein synthesis rates during overnight sleep. It remains to be assessed whether pre-sleep protein ingestion can also increase mitochondrial protein synthesis rates. Though it has been suggested that casein protein may be preferred as a pre-sleep protein source, no study has compared the impact of pre-sleep whey versus casein ingestion on overnight muscle protein synthesis rates. Objective: We aimed to assess the impact of casein and whey protein ingestion prior to sleep on mitochondrial and myofibrillar protein synthesis rates during overnight recovery from a bout of endurance-type exercise. Methods: Thirty-six healthy young men performed a single bout of endurance-type exercise in the evening (19:45 h). Thirty minutes prior to sleep (23:30 h), participants ingested 45 g of casein protein, 45 g of whey protein, or a non-caloric placebo. Continuous intravenous l-[ring-13C6]-phenylalanine infusions were applied, with blood and muscle tissue samples being collected to assess overnight mitochondrial and myofibrillar protein synthesis rates. Results: Pooled protein ingestion resulted in greater mitochondrial (0.087 ± 0.020 vs 0.067 ± 0.016%·h−1, p = 0.005) and myofibrillar (0.060 ± 0.014 vs 0.047 ± 0.011%·h−1, p = 0.012) protein synthesis rates when compared with placebo. Casein and whey protein ingestion did not differ in their capacity to stimulate mitochondrial (0.082 ± 0.019 vs 0.092 ± 0.020%·h−1, p = 0.690) and myofibrillar (0.056 ± 0.009 vs 0.064 ± 0.018%·h−1, p = 0.440) protein synthesis rates. Conclusions: Protein ingestion prior to sleep increases both mitochondrial and myofibrillar protein synthesis rates during overnight recovery from exercise. The overnight muscle protein synthetic response to whey and casein protein does not differ. Clinical Trial Registration: NTR7251. [ABSTRACT FROM AUTHOR]

Purpose: Diabetes remission is a phenomenon described in the context of drastic weight loss due to bariatric surgery or low-calorie diets. Evidence suggests that increasing the intake of plant protein could reduce the risk of type 2 diabetes. We sought for association between changes in plant protein intake in the context of 2 healthy diets without weight loss nor glucose-lowering medication, and diabetes remission in coronary heart disease patients from the CORDIOPREV study. Methods: Newly diagnosed type 2 diabetes participants without glucose-lowering treatment were randomized to consume a Mediterranean or a low-fat diet. Type 2 diabetes remission was assessed with a median follow-up of 60 months according to the ADA recommendation. Information on patient's dietary intake was collected using food-frequency questionnaires. At first year of intervention, 177 patients were classified according to changes in plant protein consumption into those who increased or decreased its intake, in order to perform an observational analysis on the association between protein intake and diabetes remission. Results: Cox regression showed that patients increasing plant protein intake were more likely to remit from diabetes than those who decreased its intake (HR = 1.71(1.05–2.77)). The remission occurred mainly at first and second year of follow-up with diminished number of patients achieving remission in the third year onwards. The increase in plant protein was associated with lower intake of animal protein, cholesterol, saturated fatty acids, and fat, and with higher intake of whole grains, fibre, carbohydrates, legumes, and tree nuts. Conclusion: These results support the need to increase protein intake of vegetal origin as dietary therapy to reverse type 2 diabetes in the context of healthy diets without weight loss.

Twenty percent of youth experience psychiatric illness before they reach adulthood, yet most do not receive adequate mental health services. Youth of color are particularly vulnerable to psychopathology considering they are more likely to experience adversity, stress, and barriers to treatment compared to White youth. Schools offer an ideal setting to address barriers to mental health care access and disparities affecting youth of color. The current study investigated the effectiveness of a school-based psychotherapy intervention for underserved youth. Participants were 141 children (ages 9–12 years; 37% Hispanic/Latinx, 58% Black/African American) assigned to either immediate or delayed intervention with the Resilience Builder Program® (RBP), a resilience group intervention for youth with social competence and emotion regulation deficits. Repeated measures analysis of variance examined differences between immediate and delayed intervention groups. Immediate intervention participants demonstrated significant improvement across behavioral, social, emotional, and executive functioning domains compared to those in the delayed intervention group. After per-family Bonferroni correction, improvements in teacher-rated emotional self-control remained statistically significant. Examination of effect sizes indicated greatest improvement across parent- and teacher-reported emotional regulation. Findings suggest that RBP demonstrates potential as an effective resilience school-based intervention for youth, especially in the realm of emotion regulation. Results also offer encouragement for universal applications of RBP to classroom settings in the future. Highlights: School-based interventions address barriers to mental health care access that disproportionately affect youth of color. This randomized controlled trial examined effectiveness of a school-based resilience intervention for underserved youth. The Resilience Builder Program® is a group intervention targeting wide-ranging social competence deficits. Results demonstrated greatest improvements in domains of emotional regulation across parent and teacher report. [ABSTRACT FROM AUTHOR]

The effect of directly observed therapy (DOT) versus self-administered therapy (SAT) on antiretroviral (ART) adherence and virological outcomes in prison has never been assessed in a randomized, controlled trial. Prisoners were randomized to receive ART by DOT or SAT. The primary outcome was medication adherence [percent of ART doses measured by the medication event monitoring system (MEMS) and pill counts] at the end of 24 weeks. The changes in the plasma viral loads from baseline and proportion of participants virological suppressed (<400 copies/mL) at the end of 24 weeks were assessed. Sixty-six percent (90/136) of eligible prisoners declined participation. Participants in the DOT arm ( n = 20) had higher viral loads than participants in the SAT ( n = 23) arm ( p = 0.23). Participants, with complete data at 24 weeks, were analyzed as randomized. There were no significant differences in median ART adherence between the DOT ( n = 16, 99% MEMS [IQR 93.9, 100], 97.1 % pill count [IQR 95.1, 99.3]) and SAT ( n = 21, 98.3 % MEMS [IQR 96.0, 100], 98.5 % pill count [95.8, 100]) arms ( p = 0.82 MEMS, p = 0.40 Pill Count) at 24 weeks. Participants in the DOT arm had a greater reduction in viral load of approximately −1 log 10 copies/mL [IQR −1.75, −0.05] compared to −0.05 [IQR −0.45, 0.51] in the SAT arm ( p value = 0.02) at 24 weeks. The proportion of participants achieving virological suppression in the DOT vs SAT arms was not statistically different at 24 weeks (53 % vs 32 %, p = 0.21). These findings suggest that DOT ART programs in prison settings may not offer any additional benefit on adherence than SAT programs. [ABSTRACT FROM AUTHOR]

With innovation in causal inference methods and a rise in non-experimental data availability, a growing number of prevention researchers and advocates are thinking about causal inference. In this commentary, we discuss the current state of science as it relates to causal inference in prevention research, and reflect on key assumptions of these methods. We review challenges associated with the use of causal inference methodology, as well as considerations for hoping to integrate causal inference methods into their research. In short, this commentary addresses the key concepts of causal inference and suggests a greater emphasis on thoughtfully designed studies (to avoid the need for strong and potentially untestable assumptions) combined with analyses of sensitivity to those assumptions.

Objectives In this study, the effects of food supplementation during pregnancy on maternal weight gain, hemoglobin (Hb) levels, and pregnancy outcomes were evaluated. Methods In this randomized controlled trial, we recruited 1360 pregnant women with a gestational age of 10 weeks who had BMI < 18.5 and hemoglobin < 10.5/dL from rural areas of the east Azerbaijan province in Iran. Rural areas were randomly assigned into two groups: food-supplemented and control areas. In food-supplemented areas the food supplement was provided (1500 kcal/d) from 10 weeks of pregnancy through to the end. Information on demographic data were collected and anthropometric and Hb measurements were taken using standard instruments. Results The average weight gain was 9.1 ± 1.8 kg and 7.9 ± 1.6 kg in supplemented and control groups respectively, which was significantly different (p = 0.001). Also, a significant time × treatment interaction in maternal average weight gain (p = 0.001) was observed. The mean Hb decreased from 12 mg/dl and 12.1 mg/dl in week 10 to 11.9 mg/dl and 11.7 mg/dl in week 20 in the supplemented and control groups respectively, which was significant only for the control group. Between-group comparisons revealed significant differences in the rates of low birth weight (LBW) infants (p = 0.001) and preterm births (p = 0.013). Conclusion for practice Food supplementation significantly reduced the prevalence of poor maternal weight gain, infants with low birth weight, and preterm births compared to no intervention.

Purpose: Recent reviews have questioned the efficacy of selective serotonin reuptake inhibitors (SSRIs) above placebo response, and their working mechanisms remain unclear. New approaches to understanding the effects of SSRIs are necessary to enhance their efficacy. The aim of this study was to explore the possibilities of using cross-sectional network analysis to increase our understanding of symptom connectivity before and after SSRI treatment.Methods: In two randomized controlled trials (total N = 178), we estimated Gaussian graphical models among 20 symptoms of the Beck Depression Inventory-II before and after 8 weeks of treatment with the SSRI paroxetine. Networks were compared on connectivity, community structure, predictability (proportion explained variance), and strength centrality (i.e., connectedness to other symptoms in the network).Results: Symptom severity for all individual BDI-II symptoms significantly decreased over 8 weeks of SSRI treatment, whereas interconnectivity and predictability of the symptoms significantly increased. At baseline, three communities were detected; five communities were detected at week 8.Conclusions: Findings suggest the effects of SSRIs can be studied using the network approach. The increased connectivity, predictability, and communities at week 8 may be explained by the decrease in depressive symptoms rather than specific effects of SSRIs. Future studies with larger samples and placebo controls are needed to offer insight into the effects of SSRIs.Trial Registration: The trials described in this manuscript were funded by the NIMH.

Purpose: Increased awareness of the importance of dietary fibre has led to increased interest in 'functional' fibre components like digestion-resistant maltodextrin (RMD). This randomized, placebo-controlled, double-blind study assessed the effects of RMD in the colonic transit time (CTT) and defecation characteristics (frequency, stool volume and consistency). Methods: Sixty-six healthy adult volunteers (32 men) who did not have a daily defecation habit had a 7-day run-in period before the 21-day intervention period with RMD or placebo. CTT and segmental CTT (SCTT) were assessed by a single abdominal X-ray film taken at the end of both periods after radiopaque marker ingestion. Defecation characteristics and intestinal functions were also assessed, which were self-reported by patients. Intragroup comparisons were evaluated by Student's paired t test, Bonferroni test and Chi-square test, while time comparisons by analysis of variance (ANOVA) and time-by-treatment interaction by repeated-measures ANOVA. Results: Fifty-seven subjects were assessed for CTT (placebo, n = 28; RMD, n = 29). In the RMD group, the total CTT, left SCTT and rectosigmoidal SCTT decreased significantly compared to baseline ( p < 0.01 each; −13.3, −4.7, −8.7 h, respectively). Significant differences between groups were observed in total CTT and left SCTT. Significant time-by-treatment interaction was observed in the RMD group for stool volume ( p = 0.014), increasing 56 % compared to baseline ( p < 0.01), while remained unchanged in the placebo group. Stool consistency was improved only in the RMD group ( p < 0.01). No adverse effects related to study products were observed. Conclusions: The results show that RMD improved CTT, stool volume, stool consistency and some intestinal functions in a healthy population. [ABSTRACT FROM AUTHOR]

Childhood internalizing problems such as anxiety and depression can have serious personal, familial and societal repercussions, including drug and alcohol abuse, delinquency, unplanned pregnancy, and even suicide. There is little research on mindfulness interventions for children with clinical levels of internalizing problems, and school-based mindfulness research with children has focused on non-clinical groups. We employed a two-stage screening and intervention procedure to evaluate an in-school mindfulness-based cognitive intervention for Hong Kong children with subclinical internalizing difficulties. Ninety-three fourth to sixth graders were screened, and twenty students (age 9-13, median age 10) highest among their peers on internalizing problems, but lowest on externalizing problems, participated in a 9-week group mindfulness-based intervention. We employed a two-phase open trial design, with random assignment to an immediate intervention group or wait-list control group. In single-trial analysis, one-tailed dependent sample t-tests showed significant decreases in both worry and in symptoms of panic disorder, obsessive compulsive disorder, generalized anxiety and overall internalizing problems. In a randomized controlled trial analysis, the immediate intervention group evidenced larger but nonsignificant reductions on almost all measures. Eighty-five percent of the participants rated the program as helpful, and 65-80 % reported improvement in handling emotions and interpersonal relationships at post-treatment, with some treatment gains maintained at 3-month follow-up. These preliminary findings have encouraging implications for implementing time-limited school-based mindfulness interventions targeting elevated childhood internalizing difficulties.

Background: Medication overuse headache (MOH) is a major clinical concern and a common health risk. Recent literature stressed the need to manage chronic headache by using integrated biobehavioral approaches. Few studies evaluated how biofeedback can be useful in MOH. The aim of the study is to evaluate in a randomized, controlled, single-blind trial the effects of biofeedback associated with traditional pharmacological therapy in the prophylactic treatment of MOH. Method: Twenty-seven subjects were randomized to frontal electromyographic (EMG) biofeedback associated with prophylactic pharmacological therapy (Bfb Group) or to pharmacological treatment alone (Control Group). The primary outcome was to evaluate the number of patients that return episodic after treatment. Secondly we evaluate the effects of frontal EMG BFB on frequency of headache and analgesic intake. Changes in coping strategies and in EMG frontalis tension were also evaluated. ANOVA was performed on all the variables of interest. Results: Our results indicate that at the end of treatment the number of patients that returned episodic in the Bfb group was significantly higher than in the Control group. Patients in the Bfb group differed from the Control group in headache frequency, amount of drug intake and active coping with pain. These outcomes were confirmed also after 4 months of follow-up. No significant effects were observed in EMG recordings. Conclusions: Biofeedback added to traditional pharmacological therapy in the treatment of MOH is a promising approach for reducing headache frequency and analgesic intake. Modification of coping cognitions in the Bfb group, as an adjunct mechanism of self-regulation, needs more evaluations to understand the role of biofeedback in changing maladaptive psychophysiological responses.

Purpose: Epidemiological evidence suggests that chronic consumption of fruit-based flavonoids is associated with cognitive benefits; however, the acute effects of flavonoid-rich (FR) drinks on cognitive function in the immediate postprandial period require examination. The objective was to investigate whether consumption of FR orange juice is associated with acute cognitive benefits over 6 h in healthy middle-aged adults. Methods: Males aged 30-65 consumed a 240-ml FR orange juice (272 mg) and a calorie-matched placebo in a randomized, double-blind, counterbalanced order on 2 days separated by a 2-week washout. Cognitive function and subjective mood were assessed at baseline (prior to drink consumption) and 2 and 6 h post consumption. The cognitive battery included eight individual cognitive tests. A standardized breakfast was consumed prior to the baseline measures, and a standardized lunch was consumed 3 h post-drink consumption. Results: Change from baseline analysis revealed that performance on tests of executive function and psychomotor speed was significantly better following the FR drink compared to the placebo. The effects of objective cognitive function were supported by significant benefits for subjective alertness following the FR drink relative to the placebo. Conclusions: These data demonstrate that consumption of FR orange juice can acutely enhance objective and subjective cognition over the course of 6 h in healthy middle-aged adults.

Purpose: Consumption of sugar-reformulated products (commercially available foods and beverages that have been reduced in sugar content through reformulation) is a potential strategy for lowering sugar intake at a population level. The impact of sugar-reformulated products on body weight, energy balance (EB) dynamics and cardiovascular disease risk indicators has yet to be established. The REFORMulated foods (REFORM) study examined the impact of an 8-week sugar-reformulated product exchange on body weight, EB dynamics, blood pressure, arterial stiffness, glycemia and lipemia. Methods: A randomized, controlled, double-blind, crossover dietary intervention study was performed with fifty healthy normal to overweight men and women (age 32.0 ± 9.8 year, BMI 23.5 ± 3.0 kg/m) who were randomly assigned to consume either regular sugar or sugar-reduced foods and beverages for 8 weeks, separated by 4-week washout period. Body weight, energy intake (EI), energy expenditure and vascular markers were assessed at baseline and after both interventions. Results: We found that carbohydrate ( P < 0.001), total sugars ( P < 0.001) and non-milk extrinsic sugars ( P < 0.001) (% EI) were lower, whereas fat ( P = 0.001) and protein ( P = 0.038) intakes (% EI) were higher on the sugar-reduced than the regular diet. No effects on body weight, blood pressure, arterial stiffness, fasting glycemia or lipemia were observed. Conclusions: Consumption of sugar-reduced products, as part of a blinded dietary exchange for an 8-week period, resulted in a significant reduction in sugar intake. Body weight did not change significantly, which we propose was due to energy compensation. [ABSTRACT FROM AUTHOR]

This pilot RCT compared the effect of a self-directed and therapist-assisted telehealth-based parent-mediated intervention for young children with ASD. Families were randomly assigned to a self-directed or therapist-assisted program. Parents in both groups improved their intervention fidelity, self-efficacy, stress, and positive perceptions of their child; however, the therapist-assisted group had greater gains in parent fidelity and positive perceptions of child. Children in both groups improved on language measures, with a trend towards greater gains during a parent-child interaction for the therapist-assisted group. Only the children in the therapist-assisted group improved in social skills. Both models show promise for delivering parent-mediated intervention; however, therapist assistance provided an added benefit for some outcomes. A full-scale comparative efficacy trial is warranted.

Purpose: Specific combinations of dietary fiber (DF) have been observed to result in improved glucose tolerance at a subsequent standardized breakfast. Arabinoxylan oligosaccharides (AXOS) are considered as DF with prebiotic potential, but so far no studies have investigated their metabolic effects in humans. This randomized cross-over study evaluated the overnight impact of breads containing AXOS-rich wheat bran extract and resistant starch (RS, Hi-Maize), separately or combined, on glucose tolerance, related metabolic parameters and markers of gut fermentation in healthy subjects. Methods: Evening reference and test products were: (1) reference white wheat flour bread (WWB), WWB supplemented with (2) AXOS and RS (WWB + AXOS + RS), (3) an increased content of either AXOS (WWB + hiAXOS) or (4) RS (WWB + hiRS). At the subsequent standardized breakfast, blood was sampled for 3 h to monitor glucose, insulin, nonesterified fatty acids, glucagon-like peptide (GLP)-1 and GLP-2. Breath hydrogen (H) and short chain fatty acids (SCFA) were measured as markers of gut fermentation, and subjective appetite was rated using visual analog scales. Results: Dose-dependent decreases in glucose responses were observed with increased AXOS over the duration of 3 h. Insulin sensitivity index was improved in the morning after the WWB + hiAXOS evening meal. An increase in breath H concentration and circulating SCFA was observed in the morning after both evening meals containing AXOS. Conclusion: The present study indicates that AXOS have the potential of improving glucose tolerance in an overnight perspective and suggested mechanisms are improved insulin sensitivity and increased gut fermentation.

Purpose: To investigate the phytochemical uptake following human consumption of Montmorency tart cherry (L. Prunus cerasus) and influence of selected phenolic acids on vascular smooth muscle cells in vitro. Methods: In a randomised, double-blinded, crossover design, 12 healthy males consumed either 30 or 60 mL of Montmorency tart cherry concentrate. Following analysis of the juice composition, venous blood samples were taken before and 1, 2, 3, 5 and 8 h post-consumption of the beverage. In addition to examining some aspects of the concentrate contents, plasma concentrations of protocatechuic acid (PCA), vanillic acid (VA) and chlorogenic (CHL) acid were analysed by reversed-phase high-performance liquid chromatography (HPLC) with diode array for quantitation and mass spectrometry detection (LCMS) for qualitative purposes. Vascular smooth muscle cell migration and proliferation were also assessed in vitro. Results: Both the 30 and 60 mL doses of Montmorency cherry concentrate contained high amounts of total phenolics (71.37 ± 0.11; 142.73 ± 0.22 mg/L) and total anthocyanins (62.47 ± 0.31; 31.24 ± 0.16 mg/L), as well as large quantities of CHL (0.205 ± 0.24; 0.410 ± 0.48 mg/L) and VA (0.253 ± 0.84; 0.506 ± 1.68 mg/L). HPLC/LCMS identified two dihydroxybenzoic acids (PCA and VA) in plasma following MC concentrate consumption. Both compounds were most abundant 1-2 h post-initial ingestion with traces detectable at 8 h post-ingestion. Cell migration was significantly influenced by the combination of PCA and VA, but not in isolation. There was no effect of the compounds on cell proliferation. Conclusions: These data show new information that phenolic compounds thought to exert vasoactive properties are bioavailable in vivo following MC consumption and subsequently can influence cell behaviour. These data may be useful for the design and interpretation of intervention studies investigating the health effects of Montmorency cherries. [ABSTRACT FROM AUTHOR]

Background: Body surface area (BSA)-based prednisolone dosing for childhood nephrotic syndrome (NS) leads to higher cumulative prednisolone doses than body weight (BW)-based dosing. The clinical effects of this higher dosage have not been evaluated in prospective studies. Methods: This parallel-group open-label randomized clinical trial enrolled 100 children with idiopathic NS, to receive BW-based ( n = 50) or BSA-based ( n = 50) prednisolone dosing by block randomization in a 1:1 ratio. The time taken for remission, relapse rate per 6 months, and adverse effects of steroids were analyzed in both groups. Results: There was no significant difference in the time taken for remission in the BW group versus the BSA group (median (IQR) 7 (4.5-9) versus 5.5 (4-8) days; p = 0.082); similar results were observed on subgroup analysis in new-onset and infrequently-relapsing NS (IFRNS). The cumulative prednisolone dosage during the enrolment episode was higher in the BSA group. The incidence of hypertension was higher ( p = 0.048) in the BSA group on per-protocol analysis. The relapse rates in the two groups per 6 months on follow-up were comparable. Conclusions: Clinical outcomes with BW-based dosing are equivalent to BSA dosing-related outcomes, although cumulative prednisolone doses are lower in the former. The practice of BW-based calculations for prescribing prednisolone in NS is a reasonable approach. [ABSTRACT FROM AUTHOR]

Purpose: Selenium is an essential trace mineral and a component of selenoproteins that are involved in the production of thyroid hormones and in regulating the immune response. We aimed to explore the effect of low-dose selenium supplementation on thyroid peroxidase antibody (TPO-Ab) concentration and thyroid function in pregnant women from a mild-to-moderate iodine-deficient population. Methods: Samples and data were from a secondary analysis of Selenium in PRegnancy INTervention (SPRINT), a double-blind, randomized, placebo-controlled study that recruited 230 women with singleton pregnancies from a UK antenatal clinic at 12 weeks of gestation. Women were randomized to receive 60 µg/day selenium or placebo until delivery. Serum thyroid peroxidase antibodies (TPO-Ab), thyrotropin (TSH) and free thyroxine (FT4) were measured at 12, 20 and 35 weeks and thyroglobulin antibodies (Tg-Ab) at 12 weeks. Results: 93.5 % of participants completed the study. Se supplementation had no more effect than placebo in decreasing TPO-Ab concentration or the prevalence of TPO-Ab positivity during the course of pregnancy. In women who were either TPO-Ab or Tg-Ab negative at baseline (Thy-Ab), TSH increased and FT4 decreased significantly throughout gestation ( P < 0.001), with no difference between treatment groups. In women who were Thy-Ab at baseline, TSH tended to decrease and was lower than placebo at 35 weeks ( P = 0.050). FT4 fell more on Se than placebo supplementation and was significantly lower at 35 weeks ( P = 0.029). Conclusions: Low-dose selenium supplementation in pregnant women with mild-to-moderate deficiency had no effect on TPO-Ab concentration, but tended to change thyroid function in Thy-Ab women.

Purpose: Wholegrain (WG) consumption is associated with reduced risk of cardiovascular disease, but clinical data on inflammation and immune function is either conflicting or limited. The objective of this study was to assess the impact of increasing WG consumption to at least 80 g/day on markers of inflammation and glucose metabolism and on phenotypic and functional aspects of the immune system, in healthy, middle-aged adults with low habitual WG intake. Methods: Subjects consumed a diet high in WG (>80 g/day) or low in WG (<16 g/day, refined grain diet) in a crossover study, with 6-week intervention periods, separated by a 4-week washout. Adherence to the dietary regimes was achieved by dietary advice and provision of a range of food products, with compliance verified by analysis of plasma alkylresorcinols (ARs). Results: On the WG intervention, WG consumption reached 168 g/day ( P < 0.001), accompanied by an increase in plasma ARs ( P < 0.001) and fibre intake ( P < 0.001), without affecting other aspects of dietary intake. On the WG arm, there were trends for lower ex vivo activation of CD4 T cells and circulating concentrations of IL-10, C-reactive protein, C-peptide, insulin and plasminogen activator inhibitor-1. The percentage of CD4 central memory T cells and circulating levels of adipsin tended to increase during the WG intervention. Conclusions: Despite the dramatic increase in WG consumption, there were no effects on phenotypic or functional immune parameters, markers of inflammation or metabolic markers.

Purpose: We compared the effects of a eucaloric moderate-fat diet (18 % protein, 36 % fat, and 46 % carbohydrate), a eucaloric low-fat high-carbohydrate diet (18 % protein, 18 % fat, and 64 % carbohydrate), and a low-calorie (33 % reduced) low-fat high-carbohydrate diet on biomarkers of systemic inflammation. Methods: We randomly assigned 102 participants (age 21-76 years and BMI 19.2-35.5 kg/m) to the three different diets for 6 weeks in a parallel design intervention trial. All foods were provided. Ninety-three participants completed all study procedures; 92 were included in the analyses. Endpoints included plasma C-reactive protein (CRP), interleukin-6 (IL-6), soluble tumor necrosis factor receptors I and II (sTNFRI and II), and adiponectin. Results: In the unadjusted primary analyses, none of the endpoints were differentially affected by the dietary interventions despite the significantly greater reductions in body weight and fat mass in participants consuming the low-calorie low-fat diet compared to the eucaloric diets ( p < 0.001). When including weight change in the model in secondary analysis, adiponectin tended to be increased with weight loss (time × weight change interaction, p = 0.051). Adjusted for weight change, adiponectin was reduced in the groups consuming the low-fat diets relative to the moderate-fat diet ( p = 0.008). No effect of the intervention diets or weight loss on CRP, IL-6, or sTNFRI and II was seen in these secondary analyses. Conclusions: In relatively healthy adults, moderate weight loss had minimal effects on systemic inflammation, and raised plasma adiponectin only modestly. A lower dietary fat and higher carbohydrate content had little impact on measures of systemic inflammation, but reduced adiponectin concentrations compared to a moderate-fat diet. The latter may be of concern given the consistent and strong inverse association of plasma adiponectin with many chronic diseases. [ABSTRACT FROM AUTHOR]

Purpose: To determine the dose-response of vitamin D3 supplementation on serum 25-hydroxyvitamin D [25(OH)D] among Chinese adults. Methods: In this 5-arm, randomized, double-blinded controlled trial, 76 healthy participants were assigned to orally administrate 0, 400, 800, 1200 or 2000 IU/d of vitamin D3 for 16 weeks. Serum 25(OH)D, parathyroid hormone, calcium, biomarkers of liver and renal function were measured at multiple time points. Results: The mean (SD) serum 25(OH)D at baseline was 31.6 (8.7) nmol/L, and the dose-response relationship was curvilinear with a plateau around 6 weeks for all doses. At week 16, 25(OH)D was increased by 6.0 (6.5), 21.7 (15.8), 26.3 (12.6), 32.0 (12.8) and 36.3 (26.0) nmol/L for 0, 400, 800, 1200 and 2000 IU/d (all P ≤ 0.002), corresponding to approximately 19, 53, 67, 77 and 80 % of reversion of vitamin D deficiency, respectively. Daily intake of 800 IU vitamin D3 reached a targeted 25(OH)D ≥ 30 nmol/L in at least 97.5 % of Chinese, but not a targeted 25(OH)D ≥ 50 nmol/L even with 2000 IU/d. Change of 25(OH)D was inversely associated with change of PTH concentration ( r = −0.39, P < 0.001) after controlling for age and sex. No between-group differences were observed in terms of the change in serum calcium, alanine transaminase, aspartate aminotransferase, gamma-glutamyltransferase and creatinine ( P ≥ 0.22). Conclusions: Supplementation with 400, 800, 1200 or 2000 IU/d vitamin D could improve the vitamin D deficiency with various degrees. Whether 2000 IU/d vitamin D3 would generate a better result without side effect requires more studies with larger samples in future. [ABSTRACT FROM AUTHOR]

The article presents the study on whether gestural information uptake is a deterministic process. The study reportedly involved several experiments and an analysis of the role of unrelated speech gestures which are not relevant to the speech they accompany. The results revealed that gestural information uptake is non-deterministic.

We examined risk factors associated with hepatitis C virus (HCV) infection among opioid-dependent patients enrolled into medication-assisted therapy (buprenorphine or methadone) to determine factors affecting chronic infection. Patients (N = 1039) were randomized as part of a larger, multisite clinical trial sponsored by the National Drug Abuse Treatment Clinical Trials Network assessing liver function. HCV status was first assessed with an antibody screen; if positive, then current infection was determined with an antigen screen testing for detectable virus. Patients were classified as HCV negative, HCV positive but have cleared the virus, or as having chronic HCV. Logistic regression analysis was used to examine demographic and behavioral correlates of the three groups. Thirty-four percent of patients were classified with chronic infection and 14 % had evidence of prior infection with apparent clearing of the virus. Chronic infection was associated with recent injection drug use and cocaine use. Chronic HCV infection was also associated with being older and Hispanic. Age, ethnicity, and current drug use increase the likelihood of being chronically infected with HCV. Strategies targeting high risk subgroups can aid in preventing further disease escalation.

Purpose: The aim was to compare postprandial lipid, insulin and vitamin D responses after consumption of three otherwise identical meals served either with baked herring, pickled herring or with baked, minced beef. Methods: Seventeen healthy, overweight men (mean age 58 years, BMI 26.4-29.5 kg/m) consumed standardized lunches together with baked herring, pickled herring or baked, minced beef on three occasions in a crossover design. Blood samples were taken just before and up to 7 h after the meal. The postprandial response was measured as serum concentrations of triglycerides (TG), total cholesterol and lipoproteins (LDL, HDL and VLDL), insulin, 25-OH vitamin D and plasma fatty acid composition. Results: There was no difference in postprandial lipid responses between the two herring meals, whereas a slower TG clearance was observed after the baked, minced beef meal. The 150 g servings of baked and pickled herring provided 3.3 and 2.8 g of long-chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), respectively, which was reflected in a substantial postprandial increase in plasma LC n-3 PUFA levels. The pickled herring contained 22 % sugar and consequently gave a higher insulin response compared with the other two meals. Conclusions: Both pickled and baked herring are good sources of LC n-3 PUFA in the diet, but the presence of sugar in pickled herring should be taken into consideration, especially if large amounts are consumed. The faster postprandial TG clearance after a meal with baked herring compared with baked beef supports previous studies on the beneficial effects of herring on cardiovascular health.

Objectives: C-reactive protein (CRP), an acute phase reactant, has been associated with atherosclerosis and has also been discussed as a target for intervention. The effects of resistance exercise on CRP are currently not clear. The present analysis investigated the response of CRP to resistance exercise in old adults. Design: Intervention study. Setting: Community. Participants: Old Icelandic adults (N = 235, 73.7 ± 5.7 years, 58.2% female). Intervention: Twelve-week resistance exercise program (3 times/week; 3 sets, 6-8 repetitions at 75-80% of the 1-repetition maximum) designed to increase strength and muscle mass of major muscle groups. Measurements: C-reactive protein (CRP). Results: Mean CRP levels were 7.1 ± 4.6 mg/dL at baseline, thirty-six (15.6%) subjects had abnormally high CRP (>10 mg/L) values at baseline. After the resistance exercise program the overall changes in CRP were minor and not significant. However, CRP decreased considerably in participants with high CRP at baseline (-4.28 ± 9.41 mg/L; P = 0.015) but increased slightly in participants with normal CRP (0.81 ± 4.58 mg/L, P = 0.021). Conclusion: Our study shows that the concentrations of circulating CRP decreased considerably after a 12-week resistance exercise program in participants with abnormally high CRP at baseline, possibly reducing thus risk for future disease. CRP changed little in participants with normal CRP at the start of the study. [ABSTRACT FROM AUTHOR]

Notably absent from the intervention literature are parent training programs targeting school-aged children with autism who have limited communication skills (Tager-Flusberg and Kasari in Autism Res 6:468-478, ). Sixty-one children with autism age 5-8 with minimal spontaneous communication received a 6-month social communication intervention including parent training. Parent-child play interactions were coded for parents' strategy implementation and children's time jointly engaged (Adamson et al. in J Autism Dev Disord 39:84-96, ). Parents mastered an average of 70 % of the strategies. Further analyses indicated some gains in implementation occurred from mere observation of sessions, while the greatest gains occurred in the first month of active coaching and workshops. Children's joint engagement was associated with parents' implementation success across time demonstrating parents' implementation was relevant to children's social engagement. [ABSTRACT FROM AUTHOR]

Objectives: The purpose of the present study was to examine the effect of a cysteine-rich whey protein (Immunocal®) supplementation in combination with resistance training on muscle strength and lean body mass (LBM) in elderly individuals. We hypothesized that the cysteine-rich whey protein (Immunocal®) group would experience a greater increase in muscle strength and lean body mass versus the control group (casein). Design: Randomized double-blind controlled intervention study. Setting: Institut de Recherches Cliniques de Montréal in Montreal, Canada. Participants: Ninety-nine non-frail elderly subjects were recruited. Intervention: Participants were randomly assigned into two groups. The experimental group received a cysteine-rich whey protein isolate (Immunocal®) (20 g/day) and the control group received casein (20 g/day) during a 135-day period. In addition, both groups performed the same resistance training program (3 times per week). Measurements: Body composition (DXA) and muscle strength (leg press) were measured. Results: Of the 99 recruited participants, 84 completed the 135-day study period. Of these, 67 subjects (33 in the casein group and 34 in the Immunocal® group) complied and used at least 80 % of the study product and completed at least 80 % of their training sessions. Results in this selected group show an increase in all three muscle strength variables (absolute, normalized by BW and by LBM) by 31.0 %, 30.9 % and 30.0 %, respectively in the casein group as well as 39.3 %, 39.9 % and 43.3 %, respectively in the Immunocal® group after the intervention (p < 0.05). The increases in muscle strength favored Immunocal® versus casein by approximately 10 % when expressed in kg per kg BW and in kg per kg LBM (p < 0.05). No significant changes were found between pre-and-post intervention in both groups for total LBM. Conclusions: Our findings showed increases in muscle strength in both groups after resistance training, however, significant additional increases were observed in muscle strength with the addition of a cysteine-rich whey protein (Immunocal®) versus casein.

Adolescents exposed to domestic violence are at high risk for dating abuse. This randomized controlled trial evaluated a dating abuse prevention program designed specifically for this risk group. Moms and Teens for Safe Dates consisted of six mailed booklets of dating abuse prevention information and interactive activities. Mothers who had been victims of domestic violence but no longer lived with the abuser delivered the program to their adolescents who had been exposed to the abuse. Mother and adolescent pairs (N = 409) were recruited through community advertising; the adolescents ranged from 12 to 16 years old and 64 % were female. Mothers and adolescents completed baseline and 6-month follow-up telephone interviews. Booklet completion in the treatment group ranged from 80 % for the first to 62 % for the last booklet. The analyses first tested whether program effects on dating abuse varied by four a priori identified moderators (mother's psychological health, the amount of adolescent exposure to domestic violence, and adolescent sex and race/ethnicity). Main effects of the program were examined when there were no differential program effects. Program effects on psychological and physical victimization and psychological and cyber perpetration were moderated by the amount of adolescent exposure to domestic violence; there were significant favorable program effects for adolescents with higher, but not lower levels of exposure to domestic violence. There were no moderated or main effects on sexual violence victimization and perpetration or cyber victimization. The findings suggest that a dating abuse prevention program designed for adolescents exposed to domestic violence can have important positive effects. [ABSTRACT FROM AUTHOR]

Background: Physical exercise has been reported to be the most effective method to improve cognitive function and brain health, but there is as yet no research on the effect of water-based exercise. Aims: The aim of the present study was to compare the effects of water-based exercise with and without cognitive stimuli on cognitive and physical functions. Methods: The design is a single-blind randomized controlled study. Twenty-one participants were randomly assigned to a normal water-based exercise (Nor-WE) group or a cognitive water-based exercise (Cog-WE) group. The exercise sessions were divided into two exercise series: a 10-min series of land-based warm-up, consisting of flexibility exercises, and a 50-min series of exercises in water. The Nor-WE consisted of 10 min of walking, 30 min of strength and stepping exercise, including stride over, and 10 min of stretching and relaxation in water. The Cog-WE consisted of 10 min of walking, 30 min of water-cognitive exercises, and 10 min of stretching and relaxation in water. Cognitive function, physical function, and ADL were measured before the exercise intervention (pre-intervention) and 10 weeks after the intervention (post-intervention). Results: Participation in the Cog-WE performed significantly better on the pegboard test and the choice stepping reaction test and showed a significantly improved attention, memory, and learning, and in the general cognitive function (measured as the total score in the 5-Cog test). Participation in the Nor-WE dramatically improved walking ability and lower limb muscle strength. Conclusion: Our results reveal that the benefits elderly adults may obtain from water-based exercise depend on the characteristics of each specific exercise program. These findings highlight the importance of prescription for personalized water-based exercises to elderly adults to improve cognitive function. [ABSTRACT FROM AUTHOR]

Background: Multidimensional tinnitus models describe dysfunctional cognitions as a complicating factor in the process of tinnitus habituation. However, this concept has rarely been investigated in previous research. Purpose: The present study investigated the effects of two cognitive-behavioral treatments on dysfunctional tinnitus-related cognitions in patients with chronic tinnitus. Furthermore, dysfunctional cognitions were examined as possible predictors of the therapeutic effect on tinnitus distress. Method: A total of 128 patients with chronic tinnitus were randomly assigned to either an Internet-delivered guided self-help treatment (Internet-based cognitive-behavioral therapy, ICBT), a conventional face-to-face group therapy (cognitive-behavioral group therapy, GCBT), or an active control group in the form of a web-based discussion forum (DF). To assess tinnitus-related dysfunctional thoughts, the Tinnitus Cognitions Scale (T-Cog) was used at pre- and post-assessment, as well as at the 6- and 12-month follow-up. Results: Multivariate ANOVAs with post hoc tests revealed significant and comparable reductions of dysfunctional tinnitus-related cognitions for both treatments (GCBT and ICBT), which remained stable over a 6- and 12-month period. Negative correlations were found between the catastrophic subscale of the T-Cog and therapy outcome for ICBT, but not for GCBT. This means a higher degree of catastrophic thinking at baseline was associated with lower benefit from ICBT directly after the treatment. Hierarchical regression analysis confirmed catastrophizing as a predictor of poorer therapy outcome regarding emotional tinnitus distress in ICBT. No associations were detected in the follow-up assessments. Conclusion: Both forms of CBT are successful in reducing dysfunctional tinnitus-related cognitions. Catastrophizing significantly predicted a less favorable outcome regarding emotional tinnitus distress in ICBT. Clinical implications of these results are described. Dysfunctional cognitions could be targeted more intensively in therapy and in future research on tinnitus. [ABSTRACT FROM AUTHOR]

Purpose: An aberrant gut microbiome has been suggested to contribute to the worldwide epidemic of obesity. In animal models, the probiotic Lactobacillus paracasei ssp. paracasei F19 (LF19) induced upregulation of genes involved in energy homoeostasis, reduced body fat and altered the serum (S) lipoprotein profile. In our previous report, feeding LF19 to infants during weaning impacted the global plasma metabolome. LF19 lowered palmitoleic acid, a monounsaturated fatty acid associated with hypertriglyceridemia and increased visceral adiposity. Therefore, we assessed if feeding LF19 from 4 to 13 months of age would have long-term effects on body composition, growth and metabolic markers. Methods: Of 179 children included in our baseline study, 120 entered the follow-up at 8-9 years of age, n = 58 in the probiotic and n = 62 in the placebo group. Body composition was measured using dual energy X-ray absorptiometry. Anthropometrics of the child and accompanying parent(s) were assessed. S-lipids, insulin, glucose and transaminases were determined after overnight fasting. Results: LF19 did not affect body mass index z-score, sagittal abdominal diameter, fat-free mass, fat mass index, truncal fat %, android or gynoid fat % and had no long-term impact on any of the assessed metabolic markers ( p > 0.05). Conclusion: Feeding LF19 during infancy did not modulate body composition, growth or any of the assessed metabolic markers at school age. The steady increase in probiotic products targeting infants and children calls for long-term follow-up of initiated probiotic intervention studies. [ABSTRACT FROM AUTHOR]

Raising a child with an Autism Spectrum Disorder (ASD) is associated with increased family chaos and parent distress. Successful long-term treatment outcomes are dependent on healthy systemic functioning, but the family impact of treatment is rarely evaluated. The Program for the Education and Enrichment of Relational Skills (PEERS) is a social skills intervention designed for adolescents with high-functioning ASD. This study assessed the impact of PEERS on family chaos, parenting stress, and parenting self-efficacy via a randomized, controlled trial. Results suggested beneficial effects for the experimental group in the domain of family chaos compared to the waitlist control, while parents in the PEERS experimental group also demonstrated increased parenting self-efficacy. These findings highlight adjunctive family system benefits of PEERS intervention and suggest the need for overall better understanding of parent and family outcomes of ASD interventions.

In a report of the effectiveness of MEHRIT, a social-interaction-based intervention for autism, Casenhiser et al. (Autism 17(2):220-241, ) failed to find a significant advantage for language development in the treatment group using standardized language assessments. We present the results from a re-analysis of their results to illustrate the importance of measuring communicative language acts (formally called 'speech acts'). Reanalysis confirmed that children in the MEHRIT group outperformed the community treatment group on measures of MLUm, number of utterances produced, and various speech act categories. The study underscores the importance of functional language measures in guiding and evaluating treatment for children with autism, and suggests that MEHRIT is effective in improving children's use of language during parent-child interactions.

Objectives: Administration of oral nutritional supplements (ONS) is an effective strategy to treat and avoid malnutrition, a persisting issue in nursing homes. However, little is known about compliance in the NH population. This study aimed to analyse the effects of compliance of NH residents with a low-volume, nutrientand energy-dense ONS on nutritional status and to identify residents' characteristics associated with compliance. Design & Setting: Randomized, controlled trial in nursing homes. Participants & Intervention: 87 nursing home residents (87±6y, 91% female) with malnutrition or at risk of malnutrition were randomly allocated to an intervention group (IG) receiving 2×125 ml ONS (2.4 kcal/ml)/d for 12 weeks, or the control group (CG) with usual care. Measurements: ONS intake was recorded daily and compliance calculated. Low and high compliance were defined as ≤30% and ≥80% of provided ONS actually consumed, respectively. Body weight (BW), BMI, upper-arm (UAC) and calf-circumference (CC) and MNA-SF were assessed at baseline and after 12 weeks. Associations between compliance and changes of nutritional parameters and residents' characteristics were analysed. Results: Compliance was high in 35.7% and low in 28.6% of the IG (n=42). BW change was significantly higher in subjects with high compliance (median +3.0 (interquartile range +2.1;+3.8) kg, n=15) than in those with low compliance (−0.2 (−2.2;+1.6) kg, n=12) and CG (−0.1 (−1.2; +0.6) kg, n=35; p<0.001), and significantly correlated with compliance in IG (r=0.691; p<0.001). Significant differences and correlations were also identified for BMI, UAC and MNA-SF. High compliance was more often observed in residents with malnutrition (66.7 vs. 27.3%) and chewing difficulties (77.8 vs. 24.2%) than in those without these conditions. Low compliance was more prevalent in residents who were immobile (45.0 vs. 13.6%), depressed (33.3 vs. 6.7%) or had gastrointestinal complaints (50.0 vs. 17.9%) (all p<0.05). Conclusions: A high compliance of nursing home residents with a low volume, nutrient- and energy dense ONS was related to a significantly improved nutritional status in comparison to low compliance and therefore enhanced the effectiveness of ONS. A higher compliance may be achieved by consideration of different residents' characteristics. [ABSTRACT FROM AUTHOR]

Background: Tramadol is widely used for acute, chronic, and neuropathic pain. Its primary active metabolite is O-desmethyltramadol (M1), which is mainly accountable for the μ-opioid receptor-related analgesic effect. Tramadol is metabolized to M1 mainly by cytochrome P450 (CYP)2D6 enzyme and to other metabolites by CYP3A4 and CYP2B6. We investigated the possible interaction of tramadol with the antifungal agents terbinafine (CYP2D6 inhibitor) and itraconazole (CYP3A4 inhibitor). Methods: We used a randomized placebo-controlled crossover study design with 12 healthy subjects, of which 8 were extensive and 4 were ultrarapid CYP2D6 metabolizers. On the pretreatment day 4 with terbinafine (250 mg once daily), itraconazole (200 mg once daily) or placebo, subjects were given tramadol 50 mg orally. Plasma concentrations of tramadol and M1 were determined over 48 h and some pharmacodynamic effects over 12 h. Pharmacokinetic variables were calculated using standard non-compartmental methods. Results: Terbinafine increased the area under plasma concentration-time curve (AUC) of tramadol by 115 % and decreased the AUC of M1 by 64 % ( P < 0.001). Terbinafine increased the peak concentration ( C) of tramadol by 53 % ( P < 0.001) and decreased the C of M1 by 79 % ( P < 0.001). After terbinafine pretreatment the elimination half-life of tramadol and M1 were increased by 48 and 50 %, respectively ( P < 0.001). Terbinafine reduced subjective drug effect of tramadol ( P < 0.001). Itraconazole had minor effects on tramadol pharmacokinetics. Conclusions: Terbinafine may reduce the opioid effect of tramadol and increase the risk of its monoaminergic adverse effects. Itraconazole has no meaningful interaction with tramadol in subjects who have functional CYP2D6 enzyme. [ABSTRACT FROM AUTHOR]

Acceptance-based psychological interventions can potentially minimize the burden of chronic pain. This randomized controlled trial evaluated an internet-delivered, guided self-help intervention based on Acceptance and Commitment Therapy (ACT). A total of 238 chronic pain sufferers from the general population were randomly allocated to either ACT (n = 82), an internet-based control condition Expressive Writing (n = 79) or a waiting list condition (n = 77). Participants completed measures at baseline, posttreatment (3 months) and at a 3-month follow-up. At follow-up, ACT participants had improved in pain interference in daily life (primary outcome) compared to participants in Expressive Writing (Cohen's d = .47), but not compared to waiting list participants ( p value = .11). Those who adhered to the ACT-intervention (48 %) did improve significantly compared to waiting list participants (d = .49). ACT-participants also showed superior improvement on depression, pain intensity, psychological inflexibility and pain catastrophizing (d: .28-.60). Significant clinical improvement was present. Especially, 28 % of ACT-participants showed general clinically relevant improvement in pain interference, as well as in pain intensity and depression (vs. Expressive Writing and waiting list 5 %). Given these findings, internet-based ACT programs may be a promising treatment modality for chronic pain. [ABSTRACT FROM AUTHOR]

This study examined whether the Program for the Education and Enrichment of Relational Skills (PEERS: Social skills for teenagers with developmental and autism spectrum disorders: The PEERS treatment manual, Routledge, New York, ) affected neural function, via EEG asymmetry, in a randomized controlled trial of adolescents with Autism spectrum disorders (ASD) and a group of typically developing adolescents. Adolescents with ASD in PEERS shifted from right-hemisphere gamma-band EEG asymmetry before PEERS to left-hemisphere EEG asymmetry after PEERS, versus a waitlist ASD group. Left-hemisphere EEG asymmetry was associated with more social contacts and knowledge, and fewer symptoms of autism. Adolescents with ASD in PEERS no longer differed from typically developing adolescents in left-dominant EEG asymmetry at post-test. These findings are discussed via the Modifier Model of Autism (Mundy et al. in Res Pract Persons Severe Disabl 32(2):124, ), with emphasis on remediating isolation/withdrawal in ASD.

Background: Suboptimal vitamin B status might affect cognitive performance in early childhood. We tested the hypothesis that short-term supplementation with folic acid and selected B vitamins improves cognitive function in healthy children in a population with relatively low folate status. Methods: We screened 1,002 kindergarten children for suboptimal folate status by assessing the total urinary para-aminobenzoylglutamate excretion. Two hundred and fifty low ranking subjects were recruited into a double blind, randomized, controlled trial to receive daily a sachet containing 220 μg folic acid, 1.1 mg vitamin B, 0.73 mg B, 1.2 μg B and 130 mg calcium, or calcium only for 3 months. Primary outcomes were changes in verbal IQ, short-term memory and processing speed between baseline and study end. Secondary outcomes were urinary markers of folate and vitamin B status, acetyl- para-aminobenzoylglutamate and methylmalonic acid, respectively, and, in a subgroup of 120 participants, blood folate and plasma homocysteine. Results: Pre- and post-intervention cognitive measurements were completed by 115 children in the intervention and 122 in the control group. Compared to control, median blood folate increased by about 50 % ( P for difference, P < 0.0001). Homocysteine decreased by 1.1 μmol/L compared to baseline, no change was seen in the control group ( P for difference P < 0.0001) and acetyl- para-aminobenzoylglutamate was 4 nmol/mmol higher compared to control at the end of the intervention ( P < 0.0001). We found no relevant differences between the groups for the cognitive measures. Conclusion: Short-term improvement of folate and homocysteine status in healthy children does not appear to affect cognitive performance. [ABSTRACT FROM AUTHOR]
