RESUMO

BACKGROUND: One third of cancer patients and survivors experience psychological distress. Previous studies have shown that online mindfulness-based cognitive therapy (eMBCT) supports cancer patients and survivors in managing distress. Lack of peer support and asynchronicity during online interventions have been reported as barriers for treatment adherence and can result in higher drop-out rates. Considering this, two new formats of eMBCT were created. The primary objective of the Buddy trial is to evaluate the (cost) effectiveness of blended and unguided eMBCT versus care as usual (CAU) on psychological distress among cancer patients and survivors. Secondary objectives include evaluating effects on other psychological outcomes and investigating working mechanisms and treatment effect moderators. METHODS: The Buddy trial is a parallel three-armed randomized controlled trial. Participants will be randomly assigned to blended therapist-assisted eMBCT, unguided individual eMBCT or CAU. Eligible participants will be Dutch-speaking adult cancer patients or survivors with access to internet. The primary outcome will be psychological distress scores as assessed by the Hospital Anxiety and Depression scale immediately post-treatment. Secondary outcome measures include fear of cancer recurrence (FCRI), fatigue (CIS-F), rumination (RRQ), mindfulness skills (FFMQ), decentering (EQ), self-compassion (SCS-SF), positive mental health (MHCSF), health related quality of life (EQ-5D), and costs associated with psychiatric illness (TiC-P). Outcome measures will be evaluated at baseline, mid-treatment, immediately post-treatment, and three-, six-, and nine-months follow-up. Possible mediators, such as engagement with interventions (TWEETS), and moderators will be also analyzed. DISCUSSION: There is room to improve eMBCT for cancer patients prior to implementation to ensure adherence and scalability. Blended and unguided eMBCT may reduce psychological distress and improve quality of life and be easily accessible to cancer patients and survivors.

RESUMO

INTRODUCTION: Mindfulness-Based Cognitive Therapy (MBCT) has been shown to reduce depressive symptoms in patients with recurrent or chronic depression. However, sequential, follow-up interventions are needed to further improve outcome for this group of patients. One possibility is to cultivate mechanisms thought to support recovery from depression, such as (self-)compassion. The current study examined the efficacy of mindfulness-based compassionate living (MBCL) in recurrently depressed patients who previously received MBCT, and consolidation effects of MBCL at follow-up. METHODS: Part one is a randomized controlled trial (RCT) comparing MBCL in addition to treatment as usual (TAU) with TAU alone. The primary outcome measure was severity of depressive symptoms. Possible mediators and moderators of treatment outcome were examined. Part two is an uncontrolled study of both intervention- and control group on the consolidation of treatment effect of MBCL over the course of a 6-months follow-up period. RESULTS: Patients were recruited between July 2013 and December 2014 (N = 122). MBCL participants (n = 61) showed significant improvements in depressive symptoms (Cohen's d = 0.35), compared to those who only received TAU (n = 61). The results at 6-months follow-up showed a continued improvement of depressive symptoms. LIMITATIONS: As MBCL was not compared with an active control condition, we have little information about the possible effectiveness of non-specific factors. CONCLUSION: MBCL appears to be effective in reducing depressive symptoms in a population suffering from severe, prolonged, recurrent depressive symptoms. To optimise the (sequential) treatment trajectory, replication of the study in a prospective sequential trial is needed. Registered at ClinicalTrials.gov:NCT02059200.

RESUMO

Cerebrovascular changes, including reduced cerebral blood flow (CBF), occur early in the development of Alzheimer disease and may accelerate disease progression. This randomized, double-blind, placebo-controlled study investigated how 6 months of treatment with the calcium antagonist nilvadipine would affect CBF in patients with mild-to-moderate Alzheimer disease. CBF was measured with magnetic resonance arterial spin labeling in whole-brain gray matter and in a priori defined regions of interest including the hippocampus. Fifty-eight patients were randomly assigned (29 in each group), of whom 22 in both groups had no magnetic resonance exclusion criteria and were medication compliant over 6 months. Mean age was 72.8±6.2 years, mean mini-mental state examination was 20.4±3.4. Nilvadipine treatment lowered systolic blood pressure (Δ=-11.5 [95% CI, -19.7 to -3.2] mm Hg; P<0.01), while whole-brain gray-matter CBF remained stable (Δ=5.4 [95% CI, -6.4 to 17.2] mL/100 g per minute; P=0.36). CBF in the hippocampus increased (left: Δ=24.4 [95% CI, 4.3-44.5] mL/100 g per minute; P=0.02; right: Δ=20.1 [95% CI, -0.6 to 40.8] mL/100 g per minute; P=0.06). There was no significant change in CBF in the posterior cingulate cortex (Δ=5.2 [95% CI, -16.5 to 27.0] mL/100 g per minute; P=0.63) or other regions of interest. In conclusion, nilvadipine reduced blood pressure and increased CBF in the hippocampus, whereas other regions showed stable or small nonsignificant increases in CBF. These findings not only indicate preserved cerebral autoregulation in Alzheimer disease but also point toward beneficial cerebrovascular effects of antihypertensive treatment.

RESUMO

Background Hypertension is common among patients with Alzheimer disease. Because this group has been excluded from hypertension trials, evidence regarding safety of treatment is lacking. This secondary analysis of a randomized controlled trial assessed whether antihypertensive treatment increases the prevalence of orthostatic hypotension (OH) in patients with Alzheimer disease. Methods and Results Four hundred seventy-seven patients with mild-to-moderate Alzheimer disease were randomized to the calcium-channel blocker nilvadipine 8 mg/day or placebo for 78 weeks. Presence of OH (blood pressure drop ≥20/≥10 mm Hg after 1 minute of standing) and OH-related adverse events (dizziness, syncope, falls, and fractures) was determined at 7 follow-up visits. Mean age of the study population was 72.2±8.2 years and mean Mini-Mental State Examination score was 20.4±3.8. Baseline blood pressure was 137.8±14.0/77.0±8.6 mm Hg. Grade I hypertension was present in 53.4% (n=255). After 13 weeks, blood pressure had fallen by -7.8/-3.9 mm Hg for nilvadipine and by -0.4/-0.8 mm Hg for placebo ( P<0.001). Across the 78-week intervention period, there was no difference between groups in the proportion of patients with OH at a study visit (odds ratio [95% CI]=1.1 [0.8-1.5], P=0.62), nor in the proportion of visits where a patient met criteria for OH, corrected for number of visits (7.7±13.8% versus 7.3±11.6%). OH-related adverse events were not more often reported in the intervention group compared with placebo. Results were similar for those with baseline hypertension. Conclusions This study suggests that initiation of a low dose of antihypertensive treatment does not significantly increase the risk of OH in patients with mild-to-moderate Alzheimer disease.

RESUMO

OBJECTIVE: The aim of this study was to examine the effectiveness of mindfulness as a treatment for adults diagnosed with ADHD. A 12-week-adapted mindfulness-based cognitive therapy (MBCT) program is compared with a waiting list (WL) group. METHOD: Adults with ADHD were randomly allocated to MBCT ( n = 55) or waitlist ( n = 48). Outcome measures included investigator-rated ADHD symptoms (primary), self-reported ADHD symptoms, executive functioning, depressive and anxiety symptoms, patient functioning, and mindfulness skills. RESULTS: MBCT resulted in a significant reduction of ADHD symptoms, both investigator-rated and self-reported, based on per-protocol and intention-to-treat analyses. Significant improvements in executive functioning and mindfulness skills were found. Additional analyses suggested that the efficacy of MBCT in reducing ADHD symptoms and improving executive functioning is partially mediated by an increase in the mindfulness skill "Act With Awareness." No improvements were observed for depressive and anxiety symptoms, and patient functioning. CONCLUSION: This study provides preliminary support for the effectiveness of MBCT for adults with ADHD.

RESUMO

BACKGROUND: Much controversy exists about the optimal management of a patent ductus arteriosus (PDA) in preterm infants, especially in those born at a gestational age (GA) less than 28 weeks. No causal relationship has been proven between a (haemodynamically significant) PDA and neonatal complications related to pulmonary hyperperfusion and/or systemic hypoperfusion. Although studies show conflicting results, a common understanding is that medical or surgical treatment of a PDA does not seem to reduce the risk of major neonatal morbidities and mortality. As the PDA might have closed spontaneously, treated children are potentially exposed to iatrogenic adverse effects. A conservative approach is gaining interest worldwide, although convincing evidence to support its use is lacking. METHODS: This multicentre, randomised, non-inferiority trial is conducted in neonatal intensive care units. The study population consists of preterm infants (GA < 28 weeks) with an echocardiographic-confirmed PDA with a transductal diameter > 1.5 mm. Early treatment (between 24 and 72 h postnatal age) with the cyclooxygenase inhibitor (COXi) ibuprofen (IBU) is compared with an expectative management (no intervention intended to close a PDA). The primary outcome is the composite of mortality, and/or necrotising enterocolitis (NEC) Bell stage ≥ IIa, and/or bronchopulmonary dysplasia (BPD) defined as the need for supplemental oxygen, all at a postmenstrual age (PMA) of 36 weeks. Secondary outcome parameters are short term sequelae of cardiovascular failure, comorbidity and adverse events assessed during hospitalization and long-term neurodevelopmental outcome assessed at a corrected age of 2 years. Consequences regarding health economics are evaluated by cost effectiveness analysis and budget impact analysis. DISCUSSION: As a conservative approach is gaining interest, we investigate whether in preterm infants, born at a GA less than 28 weeks, with a PDA an expectative management is non-inferior to early treatment with IBU regarding to the composite outcome of mortality and/or NEC and/or BPD at a PMA of 36 weeks. TRIAL REGISTRATION: This trial is registered with the Dutch Trial Register NTR5479 (registered on 19 October 2015), the registry sponsored by the United States National Library of Medicine Clinicaltrials.gov NCT02884219 (registered May 2016) and the European Clinical Trials Database EudraCT 2017-001376-28 .

RESUMO

Purpose Mindfulness-based cognitive therapy (MBCT) has been shown to alleviate psychological distress in patients with cancer. However, patients experience barriers to participating in face-to-face MBCT. Individual Internet-based MBCT (eMBCT) could be an alternative. The study aim was to compare MBCT and eMBCT with treatment as usual (TAU) for psychological distress in patients with cancer. Patients and Methods We obtained ethical and safety approval to include 245 patients with cancer with psychological distress (≥ 11 on the Hospital Anxiety and Depression Scale) in the study. They were randomly allocated to MBCT (n = 77), eMBCT (n = 90), or TAU (n = 78). Patients completed baseline (T0) and postintervention (T1) assessments. The primary outcome was psychological distress on the Hospital Anxiety and Depression Scale. Secondary outcomes were psychiatric diagnosis, fear of cancer recurrence, rumination, health-related quality of life, mindfulness skills, and positive mental health. Continuous outcomes were analyzed using linear mixed modeling on the intention-to-treat sample. Because both interventions were compared with TAU, the type I error rate was set at P < .025. Results Compared with TAU, patients reported significantly less psychological distress after both MBCT (Cohen's d, .45; P < .001) and eMBCT (Cohen's d, .71; P < .001) . In addition, post-treatment prevalence of psychiatric diagnosis was lower with both MBCT (33% improvement; P = .030) and eMBCT (29% improvement; P = .076) in comparison with TAU (16%), but these changes were not statistically significant. Both interventions reduced fear of cancer recurrence and rumination, and increased mental health-related quality of life, mindfulness skills, and positive mental health compared with TAU (all Ps < .025). Physical health-related quality of life did not improve ( P = .343). Conclusion Compared with TAU, MBCT and eMBCT were similarly effective in reducing psychological distress in a sample of distressed heterogeneous patients with cancer.

RESUMO

Background: Mindfulness trainings are increasingly offered in workplace environments in order to improve health and productivity. Whilst promising, there is limited research on the effectiveness of mindfulness interventions in workplace settings. Objective: To examine the feasibility and effectiveness of a Workplace Mindfulness Training (WMT) in terms of burnout, psychological well-being, organizational and team climate, and performance. Methods: This is a preliminary field study in four companies. Self-report questionnaires were administered up to a month before, at start of, and right at the end of the WMT, resulting in a pre-intervention and an intervention period. There was no separate control group. A total of 425 participants completed the surveys on the different time points. Linear mixed model analyses were used to analyze the data. Results: When comparing the intervention period with the pre-intervention period, significantly greater improvements were found in measures of burnout (mean difference = 0.3, p < 0.001), perceived stress (mean difference = -0.2, p < 0.001), mindfulness [mean difference = 1.0 for the Freiburg Mindfulness Inventory (FMI) and 0.8 for the Mindfulness Attention Awareness Scale (MAAS), both p < 0.001], and well-being (mean difference = 0.4, p < 0.001). Additionally, greater increases in team climate, organizational climate and personal performance were reported during the intervention compared to the pre-intervention period with largest improvements in team cooperation (mean difference = 0.3, p < 0.001), productivity (mean difference = 0.5, p < 0.001), and stress (mean difference = -0.4, p < 0.001). Effect sizes were large for mindfulness (d > 0.8), moderate for well-being, burnout and perceived stress (d = 0.5-0.8), and ranged from low to moderate for organizational and team climate and personal performance (d = 0.2-0.8). Conclusion: These preliminary data suggest that compared to the pre-intervention period, the intervention period was associated with greater reductions in burnout and perceived stress, improvements in mindfulness, well-being, and increases in team and organizational climate and personal performance. Due to design limitations, no conclusions can be drawn on the extent to which the WMT or non-specific factors such as time have contributed to the findings. Further studies, preferably using randomized controlled designs with longer follow up periods are needed to evaluate whether the associations found can be attributed to the WMT and whether these sustain after the training.

RESUMO

BACKGROUND: Mindfulness Based Cognitive Therapy (MBCT) has been shown to reduce the risk of relapse in patients with recurrent depression, but relapse rates remain high. To further improve outcome for this group of patients, follow-up interventions may be needed. Compassion training focuses explicitly on developing self-compassion, one of the putative working mechanisms of MBCT. No previous research has been done on the effectiveness of compassion training following MBCT in patients with recurrent depression. AIMS: To investigate the effectiveness of Mindfulness-Based Compassionate Living (MBCL) in reducing (residual) depressive symptoms in patients with recurrent depression who previously participated in MBCT. METHODS/DESIGN: A randomized controlled trial comparing MBCL in addition to treatment as usual (TAU) with TAU only, in patients suffering from recurrent depressive episodes who completed an MBCT course in the past. Assessments will take place at baseline, post-treatment and at six months follow-up. After the control period, patients randomized to the TAU condition will be offered MBCL as well. OUTCOME MEASURES: Primary outcome measure is severity of depressive symptoms according to the Beck Depression Inventory-II (BDI-II) at post-treatment. Secondary outcome measures are presence or absence of DSM-IV depressive disorder, rumination, self-compassion, mindfulness skills, positive affect, quality of life, experiential avoidance and fear of self-compassion. DISCUSSION: Our study is the first randomized controlled trial to examine the effectiveness of compassion training following MBCT in a recurrently depressed population. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02059200, registered 30 January 2014.

RESUMO

BACKGROUND: Major depression is a common psychiatric disorder, frequently taking a chronic course. Despite provision of evidence-based treatments, including antidepressant medication and psychological treatments like cognitive behavioral therapy or interpersonal therapy, a substantial amount of patients do not recover. Mindfulness-Based Cognitive Therapy (MBCT) has been found to be effective in reducing relapse in recurrent depression, as well as lowering symptom levels in acute depression. The effectiveness of MBCT for chronic, treatment-resistant depression has only be studied in a few pilot trials. A large randomized controlled trial is necessary to examine the effectiveness of MBCT in reducing depressive symptoms in chronic, treatment-resistant depression. METHODS/DESIGN: A randomized-controlled trial is conducted to compare MBCT with treatment-as-usual (TAU). Patients with chronic, treatment-resistant depression who have received antidepressant medication and cognitive behavioral therapy or interpersonal therapy are included. Assessments take place at baseline and post intervention/TAU-period. The primary outcome are depressive symptoms. Secondary outcomes are: remission rates, quality of life, rumination, mindfulness skills and self-compassion. Patients in the TAU condition are offered to participate in the MBCT after the post TAU-period assessment. From all completers of the MBCT (MBCT condition and patients participating after the TAU-period), follow-up assessments are taken at three and six months after the completion of the MBCT. DISCUSSION: This trial will result in valuable information about the effectiveness of MBCT in chronic, treatment-resistant depressed patients who previously received antidepressant medication and psychological treatment.

RESUMO

BACKGROUND: Adults with attention deficit hyperactivity disorder (ADHD) often present with a lifelong pattern of core symptoms that is associated with impairments of functioning in daily life. This has a substantial personal and economic impact. In clinical practice there is a high need for additional or alternative interventions for existing treatments, usually consisting of pharmacotherapy and/or psycho-education. Although previous studies show preliminary evidence for the effectiveness of mindfulness-based interventions in reducing ADHD symptoms and improving executive functioning, these studies have methodological limitations. This study will take account of these limitations and will examine the effectiveness of Mindfulness Based Cognitive Therapy (MBCT) in further detail. METHODS/DESIGN: A multi-centre, parallel-group, randomised controlled trial will be conducted in N = 120 adults with ADHD. Patients will be randomised to MBCT in addition to treatment as usual (TAU) or TAU alone. Assessments will take place at baseline and at three, six and nine months after baseline. Primary outcome measure will be severity of ADHD symptoms rated by a blinded clinician. Secondary outcome measures will be self-reported ADHD symptoms, executive functioning, mindfulness skills, self-compassion, positive mental health and general functioning. In addition, a cost-effectiveness analysis will be conducted. DISCUSSION: This trial will offer valuable information about the clinical and cost-effectiveness of MBCT in addition to TAU compared to TAU alone in adults swith ADHD.

RESUMO

PURPOSE: Danshen is the dried root extract of the plant Salvia Miltiorrhiza and it is used as traditional Chinese medicinal herbal product to prevent and treat atherosclerosis. However, its efficacy has not been thoroughly investigated. This study evaluates the effect of Danshen on hyperlipidemia and hypertension, two well known risk factors for the development of atherosclerosis. METHODS: This was a randomized, placebo-controlled, double-blind crossover study performed at a tertiary referral center. Participants were recruited by newspaper advertisement and randomized to treatment with Danshen (water-extract of the Salvia Miltiorrhiza root) or placebo for 4 consecutive weeks. There was a wash out period of 4 weeks. Of the 20 analysed participants, 11 received placebo first. Inclusion criteria were: age 40-70 years, hyperlipidemia and hypertension. At the end of each treatment period, plasma lipids were determined (primary outcome), 24 hours ambulant blood pressure measurement (ABPM) was performed, and vasodilator endothelial function was assessed in the forearm. RESULTS: LDL cholesterol levels were 3.82±0.14 mmol/l after Danshen and 3.52±0.16 mmol/l after placebo treatment (mean±SE; p<0.05 for treatment effect corrected for baseline). Danshen treatment had no effect on blood pressure (ABPM 138/84 after Danshen and 136/87 after placebo treatment). These results were further substantiated by the observation that Danshen had neither an effect on endothelial function nor on markers of inflammation, oxidative stress, glucose metabolism, hemostasis and blood viscosity. CONCLUSION: Four weeks of treatment with Danshen (water-extract) slightly increased LDL-cholesterol without affecting a wide variety of other risk markers. These observations do not support the use of Danshen to prevent or treat atherosclerosis. TRIAL REGISTRATION: ClinicalTrials.gov NCT01563770.
