5-EPIFAT trial protocol: a multi-center, randomized, placebo-controlled trial of the efficacy of pharmacotherapy for fatigue using methylphenidate, bupropion, ginseng, and amantadine in advanced cancer patients on active treatment.

BACKGROUND: Cancer-related fatigue (CRF) is still undertreated in most patients, as evidence for pharmacological treatments is limited and conflicting. Also, the efficacy of the pharmacological agents relative to each other is still unclear. Therefore, medications that may potentially contribute to improving CRF will be investigated in this head-to-head trial. Our main objective is to compare the efficacy of methylphenidate vs. bupropion vs. ginseng vs. amantadine vs. placebo in patients with advanced cancer. METHODS: The 5-EPIFAT study is a 5-arm, randomized, multi-blind, placebo-controlled, multicenter trial that will use a parallel-group design with an equal allocation ratio comparing the efficacy and safety of four medications (Methylphenidate vs. Bupropion vs. Ginseng vs. Amantadine) versus placebo for management of CRF. We will recruit 255 adult patients with advanced cancer who experience fatigue intensity ≥ 4 based on a 0-10 scale. The study period includes a 4-week intervention and a 4-week follow-up with repeated measurements over time. The primary outcome is the cancer-related fatigue level over time, which will be measured by the functional assessment of chronic illness therapy-fatigue (FACIT-F) scale. To evaluate safety, the secondary outcome is the symptomatic adverse events, which will be assessed using the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events in cancer clinical trials (PRO-CTCAE). Also, a subgroup analysis based on a decision tree-based machine learning algorithm will be employed for the clinical prediction of different agents in homogeneous subgroups. DISCUSSION: The findings of the 5-EPIFAT trial could be helpful to guide clinical decision-making, personalization treatment approach, design of future trials, as well as the development of CRF management guidelines.

Exploring the Relationship between Adherence to Therapy, Treatment Acceptability, and Clinical Outcomes in Adults with Attention-Deficit/Hyperactivity Disorder: Results from the COMPAS Multicenter Randomized Controlled Trial.

INTRODUCTION: Cognitive behavioral therapy and dialectical behavior therapy (DBT) can be effective in treating adults with ADHD, and patients generally consider these interventions useful. While adherence, as measured by attendance at sessions, is mostly sufficient, adherence to therapy skills has not been assessed. Furthermore, the relationship between patient evaluation of therapy effectiveness, treatment adherence, and clinical outcomes is understudied. OBJECTIVE: This study aimed to examine treatment acceptability and adherence in relation to treatment outcomes in a large randomized controlled trial comparing a DBT-based intervention with a nonspecific active comparison, combined with methylphenidate or placebo. METHOD: A total of 433 adult patients with ADHD were randomized. Participants reported how effective they found the therapy, and adherence was measured by attendance at therapy sessions and by self-reports. Descriptive, between-groups, and linear mixed model analyses were conducted. RESULTS: Participants rated psychotherapy as moderately effective, attended 78.40-94.37% of sessions, and used skills regularly. The best-accepted skills were sports and mindfulness. Groups receiving placebo and/or nonspecific clinical management rated their health condition and the medication effectiveness significantly worse than the psychotherapy and methylphenidate groups. Improvements in clinical outcomes were significantly associated with treatment acceptability. Subjective (self-reported) adherence to psychotherapy was significantly associated with improvements in ADHD symptoms, clinical global efficacy and response to treatment. DISCUSSION: These results further support the acceptability of DBT for adult ADHD and suggest the need to address adherence to treatment to maximize clinical improvements. Results may be limited by the retrospective assessment of treatment acceptability and adherence using an ad hoc instrument.

Polyunsaturated fatty acids (PUFA) for attention deficit hyperactivity disorder (ADHD) in children and adolescents.

BACKGROUND: Attention deficit hyperactivity disorder (ADHD) is a major problem in children and adolescents, characterised by age-inappropriate levels of inattention, hyperactivity, and impulsivity, and is associated with long-term social, academic, and mental health problems. The stimulant medications methylphenidate and amphetamine are the most frequently used treatments for ADHD, but these are not always effective and can be associated with side effects. Clinical and biochemical evidence suggests that deficiencies of polyunsaturated fatty acids (PUFA) could be related to ADHD. Research has shown that children and adolescents with ADHD have significantly lower plasma and blood concentrations of PUFA and, in particular, lower levels of omega-3 PUFA. These findings suggest that PUFA supplementation may reduce the attention and behaviour problems associated with ADHD. This review is an update of a previously published Cochrane Review. Overall, there was little evidence that PUFA supplementation improved symptoms of ADHD in children and adolescents. OBJECTIVES: To compare the efficacy of PUFA to other forms of treatment or placebo in treating the symptoms of ADHD in children and adolescents. SEARCH METHODS: We searched 13 databases and two trials registers up to October 2021. We also checked the reference lists of relevant studies and reviews for additional references. SELECTION CRITERIA: We included randomised and quasi-randomised controlled trials that compared PUFA with placebo or PUFA plus alternative therapy (medication, behavioural therapy, or psychotherapy) with the same alternative therapy alone in children and adolescents (aged 18 years and under) diagnosed with ADHD. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcome was severity or improvement of ADHD symptoms. Our secondary outcomes were severity or incidence of behavioural problems; quality of life; severity or incidence of depressive symptoms; severity or incidence of anxiety symptoms; side effects; loss to follow-up; and cost. We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: We included 37 trials with more than 2374 participants, of which 24 trials were new to this update. Five trials (seven reports) used a cross-over design, while the remaining 32 trials (52 reports) used a parallel design. Seven trials were conducted in Iran, four each in the USA and Israel, and two each in Australia, Canada, New Zealand, Sweden, and the UK. Single studies were conducted in Brazil, France, Germany, India, Italy, Japan, Mexico, the Netherlands, Singapore, Spain, Sri Lanka, and Taiwan. Of the 36 trials that compared a PUFA to placebo, 19 used an omega-3 PUFA, six used a combined omega-3/omega-6 supplement, and two used an omega-6 PUFA. The nine remaining trials were included in the comparison of PUFA to placebo, but also had the same co-intervention in the PUFA and placebo groups. Of these, four trials compared a combination of omega-3 PUFA plus methylphenidate to methylphenidate. One trial each compared omega-3 PUFA plus atomoxetine to atomoxetine; omega-3 PUFA plus physical training to physical training; and an omega-3 or omega-6 supplement plus methylphenidate to methylphenidate; and two trials compared omega-3 PUFA plus dietary supplement to dietary supplement. Supplements were given for a period of between two weeks and six months. Although we found low-certainty evidence that PUFA compared to placebo may improve ADHD symptoms in the medium term (risk ratio (RR) 1.95, 95% confidence interval (CI) 1.47 to 2.60; 3 studies, 191 participants), there was high-certainty evidence that PUFA had no effect on parent-rated total ADHD symptoms compared to placebo in the medium term (standardised mean difference (SMD) -0.08, 95% CI -0.24 to 0.07; 16 studies, 1166 participants). There was also high-certainty evidence that parent-rated inattention (medium-term: SMD -0.01, 95% CI -0.20 to 0.17; 12 studies, 960 participants) and hyperactivity/impulsivity (medium-term: SMD 0.09, 95% CI -0.04 to 0.23; 10 studies, 869 participants) scores were no different compared to placebo. There was moderate-certainty evidence that overall side effects likely did not differ between PUFA and placebo groups (RR 1.02, 95% CI 0.69 to 1.52; 8 studies, 591 participants). There was also moderate-certainty evidence that medium-term loss to follow-up was likely similar between groups (RR 1.03, 95% CI 0.77 to 1.37; 13 studies, 1121 participants). AUTHORS' CONCLUSIONS: Although we found low-certainty evidence that children and adolescents receiving PUFA may be more likely to improve compared to those receiving placebo, there was high-certainty evidence that PUFA had no effect on total parent-rated ADHD symptoms. There was also high-certainty evidence that inattention and hyperactivity/impulsivity did not differ between PUFA and placebo groups. We found moderate-certainty evidence that overall side effects likely did not differ between PUFA and placebo groups. There was also moderate-certainty evidence that follow-up was similar between groups. It is important that future research addresses the current weaknesses in this area, which include small sample sizes, variability of selection criteria, variability of the type and dosage of supplementation, and short follow-up times.

Effectiveness of neurofeedback training, behaviour management including attention enhancement training and medication in children with attention-deficit/hyperactivity disorder - A comparative follow up study.

BACKGROUND: Attention Deficit/ Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental psychiatric disorders of childhood. Treatment of ADHD includes medications and Behavioural interventions. Neurofeedback, a type of biofeedback, has been found to be useful in ADHD. It helps patients to control their brain waves consciously. However, it is not yet conclusive if it is efficacious in comparison to behavioural management training and medication. AIM: To compare the efficacy of neurofeedback training, behaviour management including attention enhancement training and medication in children with ADHD. METHOD: Ninety children between 6 and 12 years with ADHD were taken and randomly divided into 3 treatment groups equally- neurofeedback, behaviour management and medication (methylphenidate). Conners 3-P Short Scale was applied for baseline assessment. The respective interventions were given and follow up was done at the end of 3 months by using Conners 3-P Short scale to assess the improvement in the symptoms. There were 6 dropouts, the final sample size was 84. RESULTS: The medication group showed the greatest reduction of symptoms in inattention, hyperactivity, executive functioning domain (core symptoms of ADHD). No statistically significant difference was observed between Neurofeedback and Behaviour Management in these domains. Learning problems improved in all three groups, neurofeedback being the most effective followed by medication. Both Neurofeedback and Medication groups showed similar effect which was higher than the Behavioural Management group in Peer Relation. CONCLUSION: Improvement in core ADHD symptoms have been observed with all 3 interventions with medication showing the greatest improvement Neurofeedback has been superior for learning problems. Thus, Neurofeedback can be an independent or combined intervention tool for children with ADHD in outpatient department of Psychiatry.

Editorial: Accumulating Evidence for the Benefit of Micronutrients for Children With Attention-Deficit/Hyperactivity Disorder.

The first paper indicating that a central nervous system stimulant (amphetamine) could be beneficial for children with attention-deficit/hyperactivity disorder (ADHD)-like behavioral symptoms appeared in 1937.1 Over the subsequent 80 years, a range of additional stimulant (methylphenidate) and nonstimulant (atomoxetine, clonidine, guanfacine, and, most recently, viloxazine) drugs have been approved to treat children and adolescents with ADHD. These drug treatments have been the subject of a large number of randomized controlled trails (RCTs). A network meta-analysis found that using clinician ratings, amphetamine, methylphenidate, and atomoxetine were all significantly superior to a placebo.2 These findings suggest that in the short-term at least, these treatments are effective-data are sparse on the efficacy of longer-term drug treatment. However, there are longstanding worries about the use of such drug treatments with children. In particular there are concerns over possible adverse impact on growth. There are also less tangible, but important, concerns of parents as the whether it is appropriate to subject their children to the modification of behavior by drugs.3 For these reasons, there is an urgent need to develop nonpharmacological treatments for children and adolescents with ADHD. One such nonpharmacological treatment is dietary supplementation with micronutrients. In this issue of the Journal, Johnstone et al.4 present a study of micronutrients showing that, under the stringent conditions of an RCT, micronutrients substantially benefit the well-being of young people with ADHD and irritability (risk ratio [RR] = 2.97; 97.5% CI = 1.50-5.90).

Effect of Iron Supplementation in Children with Attention-Deficit/Hyperactivity Disorder and Iron Deficiency: A Randomized Controlled Trial.

OBJECTIVES: To determine the effectiveness of combined iron supplementation and methylphenidate treatment on attention-deficit/hyperactivity disorder (ADHD) symptoms in children/adolescents with ADHD and iron deficiency compared with methylphenidate alone. METHODS: In total, 116 children/adolescents with ADHD were screened for iron deficiency. Participants who exhibited iron deficiency were randomized into 2 groups (ferrous supplementation vs placebo). Vanderbilt ADHD rating scales were completed by parents and teachers at prestudy and poststudy periods. Student's t tests were used to determine improvements of Vanderbilt scores between the groups. RESULTS: Among 116 children who participated in this study, 44.8% (52/116) met the criteria for iron deficiency. Of the total 52 participants with iron deficiency, 26 were randomized to the ferrous group and 26 to the placebo group. Most participants in each group had been prescribed short-acting methylphenidate twice daily in the morning and at noon. After a 12-week study period, total parents' Vanderbilt ADHD symptom scores showed a significant improvement between the groups (mean decrement = -3.96 ± 6.79 vs 0 ± 6.54, p = 0.037). However, teachers' Vanderbilt ADHD symptom scores showed no difference between the groups. CONCLUSION: Children with ADHD and iron deficiency being on methylphenidate and iron supplementation had shown improvement of ADHD symptoms that were reported by parents.

Fatigue After Traumatic Brain Injury: A Systematic Review.

OBJECTIVE: To provide a systematic review of published interventions for posttraumatic brain injury fatigue (PTBIF). METHODS: PubMed and OneSearch were systematically searched for PTBIF interventions published between January 1, 1989, and March 31, 2019. Search results were evaluated for inclusion based on an abstract and full-text review. Inclusion criteria were (1) an investigation of an intervention, (2) participant sample including individuals with traumatic brain injury (TBI), (3) report of fatigue outcome data among individuals with TBI, and (4) articles available in English, Spanish, French, German, Afrikaans, or Dutch. A risk of bias assessment was conducted on all included publications. RESULTS: The search resulted in 2343 publications, with 37 meeting inclusion criteria for this review. Categories of PTBIF interventions were pharmacological ( n = 13), psychological ( n = 9), exercise-based ( n = 4), complementary alternative medicine ( n = 5), electrotherapeutic ( n = 3), and multimodal ( n = 3). Only methylphenidate, modafinil, and cognitive behavioral therapy interventions included multiple cohorts. Pharmacological and psychological interventions represented the groups with the lowest risk of bias. CONCLUSIONS: This review includes 37 studies, with 21 studies published after 2014. Methylphenidate and melatonin were the only pharmacological agents found to reduce fatigue in randomized controlled trials. Creatine given to children prospectively at onset of injury reduced fatigue at follow-up. Walking and water aerobics were effective exercise interventions in isolated randomized controlled studies. One multimodal study of children after concussion was more effective at reducing fatigue and postconcussion symptoms than community standard of care. Other interventions had equivocal results. Overall, more work remains to understand and develop treatments for PTBIF.

Personalized at-home neurofeedback compared to long-acting methylphenidate in children with ADHD: NEWROFEED, a European randomized noninferiority trial.

BACKGROUND: Neurofeedback is considered a promising intervention for the treatment of attention-deficit hyperactivity disorder (ADHD). NEWROFEED is a prospective, multicentre, randomized (3:2), reference drug-controlled trial in children with ADHD aged between 7 and 13 years. The main objective of NEWROFEED was to demonstrate the noninferiority of personalized at-home neurofeedback (NF) training versus methylphenidate in the treatment of children with ADHD. METHODS: The NF group (n = 111) underwent eight visits and two treatment phases of 16 to 20 at-home sessions with down-training of the theta/beta ratio (TBR) for children with high TBR and enhancing the sensorimotor rhythm (SMR) for the others. The control group (n = 67) received optimally titrated long-acting methylphenidate. The primary endpoint was the change between baseline and endpoint in the Clinician ADHD-RS-IV total score in the per-protocol population (90 NF/59 controls). TRIAL REGISTRATION: US National Institute of Health, ClinicalTrials.gov #NCT02778360. RESULTS: Our study failed to demonstrate noninferiority of NF versus methylphenidate (mean between-group difference 8.09 90% CI [8.09; 10.56]). However, both treatment groups showed significant pre-post improvements in core ADHD symptoms and in a broader range of problems. Reduction in the Clinician ADHD-RS-IV total score between baseline and final visit (D90) was 26.7% (SMD = 0.89) in the NF and 46.9% (SMD = 2.03) in the control group. NF effects increased whereas those of methylphenidate were stable between intermediate and final visit. CONCLUSIONS: Based on clinicians' reports, the effects of at-home NF were inferior to those of methylphenidate as a stand-alone treatment.

Tratamiento del trastorno de déficit de atención con hiperactividad en población pediátrica: revisión bibliográfica / Treatment of attention deficit hyperactivity disorder in the pediatric population: literature review

El Trastorno por Déficit de Atención con Hiperactividad (TDAH) es un trastorno del comportamiento común en la infancia, caracterizado por la presencia de hiperactividad, impulsividad, problemas de atención y dificultades en las interacciones sociales. El objetivo de esta revisión bibliográfica fue identificar los tratamientos disponibles para el manejo del TDAH, tanto farmacológicos como no farmacológicos. La búsqueda se realizó en PubMed y Google Scholar, recopilando 285 artículos. Se excluyeron aquellos que no estaban en inglés o español, incluían población adulta o no se ajustaban al propósito de la revisión. Se seleccionaron 48 artículos y se incluyeron finalmente 30 para la lectura. Se concluye que la evidencia sugiere un enfoque combinado de tratamiento farmacológico y no farmacológico. Entre los tratamientos farmacológicos, los estimulantes como el metilfenidato siguen siendo la opción de primera línea. Además, hay estudios preliminares que respaldan la suplementación de hierro, vitamina D, zinc, omega 3, ginseng rojo y proteína de suero de leche. En cuanto a los tratamientos no farmacológicos, hay una amplia variedad de estrategias terapéuticas, como psicoeducación, entrenamiento en habilidades sociales, terapia de aceptación y compromiso, entrenamiento para padres, neurofeedback, aplicaciones de juegos móviles, actividad física, higiene del sueño, estimulación magnética transcraneal, acupuntura y terapia asistida por caballos. Aunque estos estudios son prometedores, muchos son incipientes, y se requiere más investigación en este campo.

Attention Deficit Hyperactivity Disorder (ADHD) is a common behavioral disorder in childhood, characterized by the presence of hyperactivity and impulsivity, attention problems, and difficulties in social interactions. The objective of this bibliographic review was to identify the available treatments for the non-pharmacological and pharmacological management of ADHD. A search was conducted in PubMed for articles published in the last 5 years and in Google Scholar since 2018, resulting in 285 collected articles. Articles not in English or Spanish, including adults in their population, or not fitting the purpose of this review were excluded. Out of 48 selected articles for reading, 30 were finally included. The available evidence suggests a combined approach of pharmacological and non-pharmacological treatment. Stimulants such as methylphenidate continue to be the first-line treatment among pharmacological measures. Incipient studies recommend the use of iron, vitamin D, zinc, omega 3, red ginseng, and whey protein supplementation. Non-pharmacological measures include a variety of therapeutic strategies, such as psychoeducation, training in social skills, acceptance and commitment therapy, training for parents, neurofeedback, mobile game applications, physical activity, sleep hygiene, transcranial magnetic stimulation, acupuncture, and horse-assisted therapy. While these studies show promise, most are still in the early stages, emphasizing the need for further research in this area.

Evaluation of the efficacies of methylphenidate and biofeedback treatments in giggle incontinence: One-year follow-up study.

INTRODUCTION: Giggle incontinence is a type of urinary incontinence (GI) that occurs with laughing due to the urinary bladder's involuntary contraction leading to complete emptying. There are studies in the literature that biofeedback therapy or methylphenidate can be effective in the treatment of this condition. OBJECTIVE: This study aimed to compare the efficacies of biofeedback therapy and methylphenidate treatment in patients with GI. STUDY DESIGN: In this non-randomized observational study, children aged 5-18 years who were diagnosed with GI between January 2014 and December 2019 were included in the study. Patients who were treated by biofeedback were assigned to Group 1, while patients who were given methylphenidate treatment were placed in Group 2. Patients in Group 1 were treated with biofeedback, which was planned once a week for four weeks and once a month for the following two months. They continued their pelvic floor strengthening exercises at home for the following nine months. Patients in Group 2 were prescribed 5 mg oral methylphenidate qid for three months. Patients in both groups were followed up with 3-month intervals within a year. The results were classified as complete response, partial response or no response as per The International Children's Continence Society (ICCS) recommendations. RESULTS: The study population consisted of 38 patients with GI. Mean age of the patients was 7.7 (5-11). Among these patients, 31 (81.5%) were female, while 7 (18.4%) were male. Two groups were similar regarding mean patient age and gender distribution. There was no difference between the two groups regarding treatment responses evaluated during the 1st, 3rd, and 6th-month outpatient clinic encounters (p > 0.05). However, treatment responses assessed during the 12th-month outpatient clinic encounter revealed 15 (94.1%) patients with complete response in Group 1, while there were 10 (55.6%) patients who showed complete response in Group 2, with a significant difference (p = 0.03). DISCUSSION: Our study showed that treatment responses were reduced after discontinuation of methylphenidate. We achieved high complete response rates in the first, third, sixth, and twelfth-month assessments by biofeedback treatment. CONCLUSIONS: Significantly more favorable treatment outcomes were achieved with biofeedback therapy than methylphenidate treatment after completion of 1-year. Multi-center, randomized studies are needed to evaluate efficacy and safety.

Adjuvant effects of vitamin A and vitamin D supplementation on treatment of children with attention-deficit/hyperactivity disorder: a study protocol for a randomised, double-blinded, placebo-controlled, multicentric trial in China.

INTRODUCTION: Approximately 7.2% of children in the world suffer from attention-deficit/hyperactivity disorder (ADHD). Due to the availability of the osmotic-release oral-system methylphenidate, ADHD currently has a remission rate of up to 30.72%. Nevertheless, it has been reported that patients with ADHD tend to exhibit vitamin A and vitamin D deficiency, which may aggravate the symptoms of ADHD. This study aims to determine the effect of vitamin A and vitamin D supplementation as adjunctive therapy to methylphenidate on the symptoms of ADHD. METHODS AND ANALYSIS: This is a parallel, prospective, interventional multicentric study. Patients will be enrolled from the southern, central and northern parts of China. A target of 504 patients will be followed for 8 weeks. They will be allocated into three groups (vitamin AD, vitamin D and placebo) and administered the interventions accordingly. Data on changes in the symptoms of ADHD as well as changes in the serum concentrations of vitamin A and vitamin D will be recorded. Both responders and nonresponders based on the sociodemographic and clinical data will also be described to mitigate selection bias. ETHICS AND DISSEMINATION: This study is performed in accordance with the Declaration of Helsinki and was approved by the Institutional Review Board of Children's Hospital of Chongqing Medical University, China (approval number: (2019) IRB (STUDY) number 262). The results of the trial will be reported in peer-reviewed scientific journals and academic conferences regardless of the outcomes. TRIAL REGISTRATION NUMBER: NCT04284059.

Ilex kudingcha C.J. Tseng Mitigates Phenotypic Characteristics of Human Autism Spectrum Disorders in a Drosophila Melanogaster Rugose Mutant.

Autism spectrum disorders (ASD) have heterogeneous etiologies involving dysfunction of central nervous systems, for which no effective pan-specific treatments are available. Ilex kudingcha (IK) C.J. Tseng is a nootropic botanical used in Asia for neuroprotection and improvement of cognition. This study establishes that a chemically characterized extract from IK (IKE) mitigates behavioral traits in the Drosophila melanogaster rugose mutant, whose traits resemble human ASD, and examines possible mechanisms. IKE treatment significantly ameliorated deficits in social interaction, short-term memory, and locomotor activity in Drosophila rugose, and significantly increased synaptic bouton number of size more than 2 µm2 in the neuromuscular junctions (NMJs) of Drosophila rugose. To clarify mechanism(s) of IKE action, methylphenidate (MPH), a dopamine transporter inhibitor, was included as a reference drug in the behavioral assays: MPH significantly improved social interaction and short-term memory deficit in Drosophila rugose; administration of the dopamine D1 receptor antagonist SCH23390 and dopamine D2 receptor antagonist sulpiride reversed the ameliorative effects of both MPH and IKE on the social interaction deficits of Drosophila rugose. To extend analysis of IKE treatment to the vertebrate central nervous system, ASD-associated gene expression in mouse hippocampus was studied by RNA-seq: IKE treatment altered the expression of genes coding phosphoinositide 3-kinases/protein kinase B (PI3K-Akt), proteins in glutamatergic, dopaminergic, serotonergic, and GABAergic synapses, cAMP response element-binding protein (CREB), and RNA transporter proteins. These results provide a foundation for further analysis of IKE as a candidate for treatment of some forms of ASD.

Effects of methylphenidate on sensory and sensorimotor gating of initially psychostimulant-naïve adult ADHD patients.

Deficient information processing in ADHD theoretically results in sensory overload, which in turn may underlie its symptoms. If this sensory overload is caused by deficient filtering of environmental stimuli, then one would expect finding deficits in P50 gating and prepulse inhibition of the startle reflex (PPI). Previous reports on these measures in ADHD have shown inconsistent findings, which may have been caused by either medication use or comorbidity (e.g. ASD). The primary aim of this study was therefore to explore P50 suppression and PPI in adult, psychostimulant-naïve patients with ADHD without major comorbidity, and to examine the effects of 6 weeks treatment with methylphenidate (MPH) on these measures. A total of 42 initially psychostimulant-naive, adult ADHD patients without major comorbidity and 42 matched healthy controls, were assessed for their P50 gating, PPI, and habituation/sensitization abilities at baseline and after 6 weeks of treatment with methylphenidate. Although six weeks of treatment with MPH significantly reduced symptomatology as well as improved daily life functioning in our patients, it neither significantly affected PPI, P50 suppression nor sensitization, but habituation unexpectedly decreased. The absence of PPI and P50 suppression deficits in our patients in the psychostimulant-naïve state indicates no gating deficits. In turn, this suggests that the difficulties to inhibit distraction of attention by irrelevant stimuli that many patients with (adult) ADHD report, have a different origin than the theoretical causes of sensory overload frequently reported in studies on patients with schizophrenia.

The Efficacy of Acupuncture Treatment for Attention Deficit Hyperactivity Disorder: A Systematic Review and Meta-Analysis.

BACKGROUND: This study aimed to assess the efficacy of acupuncture for treating attention deficit hyperactivity disorder (ADHD) in children and adolescents. PATIENTS AND METHODS: Systematic review and meta-analysis including randomized controlled trials that compared the effects of acupuncture treatment (AT) with pharmacotherapy (methylphenidate hydrochloride, MPH) among patients with ADHD. A total of 12 electronic databases were searched from inception until February 3, 2020. The main outcomes were the effective rate and post-treatment hyperactivity scores. We also assessed the incidence of adverse events and follow-up course. RESULTS: A total of 10 studies involving 876 patients were included in this study. The meta-analysis revealed that AT yielded a significantly higher effective rate than MPH (odds ratio 2.239, 95% CI 1.438-3.487, p < 0.001, 8 studies), and that AT can reduce the hyperactivity scores to a lesser degree than MPH (standardized mean difference = -0.882, 95% CI -1.295 to -0.469, p < 0.001, 3 studies). Two studies reported no adverse events in the AT group, while one study suggested that AT can reduce adverse drug reactions. Furthermore, 3 studies concluded that the effects of AT were maintained, even after completion of treatment. CONCLUSION: This study suggests that AT may be more beneficial than MPH therapy for ADHD patients. However, the evidence may be highly limited, especially considering the outcome of hyperactivity scores with the high risk of bias, very low GRADE, and small number of studies. Thus, further studies of rigorous design and high quality are needed to confirm and strengthen the results, especially in the Western part of the world. Additionally, well-designed randomized controlled trials that evaluate adverse events and include a long-term follow-up should be conducted to determine the efficacy, safety, and side effects of AT for ADHD in children and adolescents.

Sleep disturbance in patients with cancer: a feasibility study of multimodal therapy.

BACKGROUND: Our aim was to determine feasibility and effect sizes of bright light therapy (BLT), melatonin (MLT), methylphenidate (MP) and eight combinations (BLT+MLT+MP, BLT+MLT, BLT+MP, BLT alone, MLT+MP, MLT alone, MP alone, placebo for BLT, MLT and MP) defined as multimodal therapy (MMT), to improve sleep quality (SQ) (Pittsburgh Sleep Quality Index (PSQI)) from baseline to day 15. We also examined the effects of MMT on insomnia, fatigue, depression, quality of life and actigraphy. METHODS: Patients with advanced cancer with poor SQ (PSQI ≥5) were eligible. Using a double-blind randomised factorial study design, patients were randomised into 1 of the 8 arms for 2 weeks. Feasibility and effect sizes were assessed. RESULTS: 81% (54/67) of randomised patients completed the study. There were no differences in the demographics and SQ between groups. The adherence rates for BLT, MLT and MP were 93%, 100% and 100%, respectively. BLT+MLT+placebo of MP; BLT+placebo of MLT+placebo of MP; BLT+MLT+MP showed an effect size (Cohen's d) for change in PSQI scores of 0.64, 0.57 and 0.63, respectively. PSQI change using linear regression showed BLT (n=29) has effect size of 0.46, p=0.017; MLT (n=26), 0.24, p=0.20; MP (n=26), 0.06, p=0.46. No significant differences were observed in scores for insomnia, fatigue, depression, quality of life and actigraphy. There were no differences in adverse events by groups(p=0.80). CONCLUSIONS: The use of MMT to treat SQ disturbance was feasible. BLT+MLT showed the most promising effect size in improvement in SQ, and additional larger studies are needed. TRIAL REGISTRATION NUMBER: NCT01628029.

Diagnosis and management of an inappropriate sinus tachycardia in adolescence based upon a Holter ECG: A retrospective analysis of 479 patients.

Inappropriate sinus tachycardia (IST) is a common disease of the autonomic nervous system in children and adults. Diagnosis and treatment of IST in adolescents is not well defined. In this retrospective study, we tested our hypothesis regarding autonomic dysfunction in childhood by analyzing 24-h heart rate variability (HRV) in 479 children, with a mean age of 13.7 ± 2.1 years, who were referred to the outpatient clinic in the Pediatrics Department within the last 15 years. Seventy-four adolescents with a mean 24-h heart rate ≥ 95 bpm (our cut-off for an IST based upon 66 healthy controls) were deemed to have IST. We found the risk of IST to be high in adolescents with attention deficit disorder (OR = 3.5,p<0.001), pre-hypertension (OR = 2.5, p = 0.043) and hypertension (OR = 2.1,p = 0.02); insignificantly enhanced in children with short stature (OR = 1.9,p = 0.19), surgically-treated congenital heart disease (OR = 1.4,p = 0.51) and obesity without hypertension (OR = 1.4;p = 0.25); and negligible in adolescents with anorexia nervosa (OR = 0.3, p = 0.26) and constitutional thinness (OR = 0.9,p = 0.89). IST was associated with a significant decrease in global HRV and elevated blood pressures, indicating an enhanced cardiovascular risk. Methylphenidate did not increase 24-h heart rates, whereas omega-3 fatty acid supplementation significantly decreased elevated heart rates and increased HRV in adolescents with IST. In this retrospective analysis, 15.4% of adolescents suffered from IST with a 24-h heart rate ≥ 95 bpm, predominately due to attention deficit disorder and hypertension.

[Pharmacotherapy of attention deficit hyperactivity disorder in adults]. / Medikamentöse Therapie der Aufmerksamkeitsdefizit­/Hyperaktivitätsstörung im Erwachsenenalter.

Pharmacotherapy is a central component in the context of an overall therapeutic concept in the treatment of adults with attention deficit hyperactivity disorder (ADHD). In this concept psychosocial interventions with psychoeducation or specific psychotherapy measures also play an important role. In adults three compounds are currently approved for the pharmacological treatment of ADHD in Germany. The long-acting stimulants retarded methylphenidate preparations and lisdexamfetamine can be prescribed. Alternatively, the adrenergic uptake inhibitor atomoxetine can be used. In several meta-analyses good effectiveness and tolerance of these drugs on ADHD psychopathology has been shown. They also improve ADHD-related disorders of emotional regulation capability and disorganization in everyday life. Importantly, an improvement in everyday functionality and quality of life under medication could also be shown in several studies. In this review the evidence for pharmacotherapy of ADHD and its implementation into treatment of adult patients is presented.

Natural Health Product-Drug Interaction Causality Assessment in Pediatric Adverse Event Reports Associated with Attention-Deficit/Hyperactivity Disorder Medication.

Background: Some pediatric patients with attention-deficit/hyperactivity disorder (ADHD) use natural health products (NHPs) such as herbal remedies. Although herbal remedies are generally considered to be safe when they are used appropriately, they may contain active components that can interact with medications being used concurrently, with potential for NHP-drug interactions leading to adverse events. Objectives: The objectives of this study were (1) to identify adverse event reports (AERs) involving commonly used herbal remedies and ADHD prescription medicines in children and adolescents; (2) to evaluate the quality of collected AERs; and (3) to assess whether NHP-drug interactions can be causally linked to reported adverse events. Methods: We systematically searched the FDAble database (FDAble.com) for herbal remedies commonly used by patients (4-18 years old) also taking ADHD drugs from 1997 to 2015. We assessed the completeness of the AERs and used three causality assessment tools modified for NHPs (Naranjo Adverse Drug Reaction Probability Scale, HORN Drug Interaction Probability Scale, and World Health Organization Uppsala Monitoring Centre Scale). Results: Of the 23 identified AERs involving both an herbal remedy and an ADHD prescription medication, most involved multiple (>3) substances with inadequate detail to assess multiple potential interactions. Following data extraction and evaluation of completeness, five AERs involving only one herbal remedy and one ADHD medication were evaluated for causality. An NHP-drug interaction was assessed to be probable in one case and to be possible in another. Both these reports involved a methylphenidate formulation and St. John's wort. Conclusions: Eighteen of the 23 identified AERs involving both an herbal remedy and an ADHD drug also involved other multiple ingredient products. The reporting quality was poor for the five AERs examined. Further research is needed to study the interaction between St. John's wort and methylphenidate.
