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.

Effects of methylphenidate on femoral bone growth in male rats.

The use of Methylphenidate (MP) can have adverse effects on bone growth and mineralization. This study aimed to investigate the underlying pathophysiology of MP-induced skeletal deficits in growing rats using stereological and immunohistochemical methods. Male rats, aged 4 weeks, were orally treated with MP through an 8-h/day water drinking protocol. The rats (n=30) were randomly divided into three groups: MP-High Dose (30/60 mg/kg/day MP), MP-Low Dose (4/10 mg/kg/day MP), and control (water only). After 13 weeks, the femoral bones were assessed using calliper measurements, dual-energy X-ray absorptiometry, and biomechanical evaluation. The total femur volume, cartilage volume, growth zone volume, and volume fractions were determined using the Cavalieri method. Immunohistochemical analyses were conducted using alkaline phosphatase and anti-calpain antibody staining. Rats exposed to MP exhibited significant reductions in weight gain, femoral growth, bone mineralization, and biomechanical integrity compared to the control group. The total femoral volume of MP-treated rats was significantly lower than that of the control group. The MP-High Dose group showed significantly higher ratios of total cartilage volume/total femoral volume and total growth zone volume/total femoral volume than the other groups. Immunohistochemical evaluation of the growth plate revealed reduced osteoblastic activity and decreased intracellular calcium deposition with chronic MP exposure. The possible mechanism of MP-induced skeletal growth retardation may involve the inhibition of intracellular calcium deposition in chondrocytes of the hypertrophic zone in the growth plate. In this way, MP may hinder the differentiation of cartilage tissue from bone tissue, resulting in reduced bone growth and mineralization.

The effect of methylphenidate for giggle incontinence in children.

INTRODUCTION: Giggle incontinence (GI) is a rare form of urinary incontinence that occurs during or immediately after laughing due to involuntary and complete bladder emptying. Few studies in the literature report that methylphenidate can be effective in treatment of this condition. OBJECTIVE: The aim of this study is to characterize children with GI and evaluate their response to methylphenidate, as well as describe treatment duration, dosage of methylphenidate, relapse rates after discontinuation of medication, and side effects. METHODS: Medical records and 48-h frequency-volume charts from children treated with methylphenidate for GI in the period January 2011-July 2021 were retrospectively analyzed. RESULTS: Eighteen children were diagnosed with GI and fulfilled inclusion criteria. Fifteen patients were included in analysis, as 3 out of 18 children decided not to take the methylphenidate that was prescribed. In total, 14 out of the 15 GI patients treated with methylphenidate experienced clinical effect. All patients included in the study had methylphenidate prescribed in a dose range of 5-20 mg daily. Treatment duration ranged from 30 to 1001 days, with a median of 152 days (IQR 114, 243.5). Ten children experienced complete response and two of those reported symptom relapse after discontinuation of the methylphenidate. Only mild and short-lasting side effects were reported by two patients. DISCUSSION: Our study demonstrates that methylphenidate is an effective treatment in children diagnosed with GI. Side effects are mild and uncommon.

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.

Consumo de psicoestimulantes por estudantes de medicina em um centro universitário privado / Consumption of psychostimulants by medical students in a private university center

O consumo de psicoestimulantes tem crescido exponencialmente, sobretudo entre estudantes de medicina, na busca por aumentar o rendimento acadêmico. Atualmente, a extensa carga horária de aulas e estudos, exigências de produtividade e altos níveis de estresse podem desencadear o uso. Objetivo: Analisar o uso de psicoestimulantes por estudantes do curso de Medicina de um Centro Universitário privado em Minas Gerais. Métodos: Foi realizado um estudo descritivo, quantitativo, com delineamento transversal entre os discentes do 1° ao 5° ano do curso de Medicina no 2° semestre de 2021. Os participantes responderam ao questionário semi-estruturado elaborado pelos autores. Os dados obtidos foram tabulados no software Statistical Product and Service Solutions. Resultados: Dos 244 entrevistados, cerca de 57.4% faziam uso de algum psicoestimulante. Houve maior uso entre os estudantes do 2° ano e as principais substâncias utilizadas foram: cafeína (85%), energético (65%) e metilfenidato (60%). A melhora na concentração (97%) foi o efeito mais percebido pelos usuários, seguido de redução do sono (83%) e melhora de raciocínio (80%). Muitos consideraram que os estimulantes cerebrais têm o potencial de melhorar o rendimento acadêmico, mas pode reduzir a qualidade do sono e consequentemente torná-los susceptíveis a outras enfermidades. Conclusão: É notável que existe uso abusivo de estimulantes cerebrais, sendo fundamental o trabalho em conjunto entre instituição de ensino e familiares, em prol da prevenção e do controle de danos causados por esse hábito

The consumption of psychostimulants has grown exponentially, especially among medical students, in the quest to increase academic performance. Currently, the extensive workload of classes and studies, productivity demands and high levels of stress can trigger use. Objective: To analyze the use of psychostimulants by medical students at a private University Center in Minas Gerais. Methods: A descriptive, quantitative, cross-sectional study was carried out among students from the 1st to the 5th year of the medicine course in the 2nd semester of 2021. The participants answered the semi-structured questionnaire prepared by the authors. The data obtained were tabulated in the Statistical Product and Service Solutions software. Results: Of the 244 respondents, about 57.4% used some psychostimulant. There was greater use among 2nd year students and the main substances used were: caffeine (85%), energy drink (65%) and methylphenidate (60%). Improved concentration (97%) was the effect most perceived by users, followed by reduced sleep (83%) and improved thinking (80%). Many considered that brain stimulants have the potential to improve academic performance, but can reduce sleep quality and consequently make them susceptible to other illnesses. Conclusion: It is notable that there is abusive use of brain stimulants, and it is essential to work together between educational institutions and family members in order to prevent and control the damage caused by this habit

[Effect of Rehmanniae Radix Praeparata on energy metabolism in prefrontal cortex of rats with attention deficit hyperactivity disorder based on "static Yin and dynamic Yang" theory].

The present study investigated the effect of Rehmanniae Radix Praeparata(RRP) on the energy metabolism of prefrontal cortex(PFC) of spontaneously hypertensive rats with attention deficit hyperactivity disorder(ADHD) based on the "static Yin and dynamic Yang" theory.Thirty spontaneously hypertensive male rats aged 3 weeks were randomly divided into a model group, a methylphenidate(MPH) group(2 mg·kg~(-1)), and an RRP group(2.4 g·kg~(-1)).Wistar-Kyoto(WKY) male rats of the same age were assigned to the normal group.Rats were treated with corresponding drugs twice per day, and those in the model group and the normal group received the same volume of 0.9% sodium carboxymethyl cellulose(CMC-Na) solution by gavage.The open-field test was performed to evaluate the spontaneous and impulsive behaviors of rats before treatment and on the 4~(th) week after treatment.Four weeks after treatment, PFC was isolated and mitochondria were prepared.The content of adenosine triphosphate(ATP), adenosine diphosphate(ADP), and adenosine monophosphate(AMP) in the PFC was determined by high-performance liquid chromatography(HPLC), and energy charge(EC) was calculated.The parameters related to mitochondrial respiratory function were measured by the Clark oxygen electrode, specifically, state 3 respiration(ST3), state 4 respiration(ST4), and respiratory control rate(RCR).Enzymatic activities of succinate dehydrogenase(SDH), cytochrome C oxidase(COX), Na~+-K~+-ATPase, and Ca~(2+)-Mg~(2+)-ATPase were measured by chemical colorimetry.Mitochondrial permeability transition pore(mPTP) opening was measured by spectrophotometry.Protein expression of glucose transporter 1(GLUT1) and GLUT3 in PFC was tested by Western blot.Compared with the results in the model group, RRP could significantly reduce the total distance of movement, vertical times, and distance in the central area in the open field test(P<0.05 or P<0.01), increase the content of ATP and EC, decrease the content of AMP(P<0.05), elevate ST3 and RCR(P<0.05), potentiate activities of SDH, COX, Na~+-K~+-ATPase, and Ca~(2+)-Mg~(2+)-ATPase(P<0.05 or P<0.01), inhibit the opening of mPTP, and increase the expression levels of GLUT1 and GLUT3 proteins(P<0.05).It was inferred that RRP could inhibit hyperacti-vity and impulsivity by improving the energy metabolism disorder in PFC of ADHD rats, and its mechanism may be related to the improvement of mitochondrial respiratory function, potentiation of Na~+-K~+-ATPase, Ca~(2+)-Mg~(2+)-ATPase, and mitochondrial respiratory enzymes, inhibition of the opening of mPTP, and up-regulation of the expression of glucose transporter proteins.This study initially reveals the biological connotation of the "static Yin and dynamic Yang" theory in ADHD.

The effect of Rosa canina L. and a polyherbal formulation syrup in patients with attention-deficit/hyperactivity disorder: a study protocol for a multicenter randomized controlled trial.

BACKGROUND: Attention-deficit/hyperactivity disorder (ADHD) is the most common behavioral disorder in childhood and adolescence. A number of these patients do not respond to the current pharmacological treatments and there may also be drug side effects. This study aims to determine the efficacy and safety of two herbal medicine products, including Rosa canina L. (RC) and a polyherbal formulation (PHF) syrup, on the clinical manifestations of ADHD in children and adolescents. METHODS: Ninety ADHD patients based on DSM-5 diagnostic criteria will be randomly assigned equally into three groups: (1) RC syrup + methylphenidate (MP), (2) PHF syrup + MP, and (3) placebo + MP according to the inclusion criteria (30 subjects in each group). The syrup dosage is 5cc every 8 h, and MP will have a stabilized dose for 8 weeks during the study. Moreover, Conner's questionnaires will be completed by the teacher and parents before the intervention and then every 4 weeks. Also, the Child Symptom Inventory-fourth edition (CSI-4) and temperament questionnaires will be completed before the intervention and every 4 weeks until 2 months. DISCUSSION: This trial is the first experiment to determine the effects of RC and PHF syrups on the clinical manifestations of ADHD in children and adolescents. Our findings provide new insight into the effect of these herbal products on the clinical manifestations of ADHD. TRIAL REGISTRATION: Iranian Registry of Clinical Trials IRCT20190923044855N1 .

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.

Effect of methylphenidate at different doses on new bone formation with rapid maxillary expansion: A micro-CT and histomorphometric study in rats.

OBJECTIVES: This study aimed to evaluate the effect of systemically administered methylphenidate hydrochloride (MPH) on new bone formation in premaxillary suture after rapid maxillary expansion (RME). SETTING AND SAMPLE POPULATION: Thirty-three Wistar rats were divided into four groups: Group 1 (high dose, 30/60 mg/kg MPH), Group 2 (low dose, 4/10 mg/kg MPH), Group 3 (positive control) and Group 4 (negative control). METHODS: RME was applied on the 70th day of the study. A 5-day RME period was followed by a 12-day retention period. The experiment was terminated on the 87th day. Micro-CT for radiological evaluation, haematoxylin-eosin and Masson's trichrome staining methods were used for histomorphometric evaluation. RESULTS: Among experimental groups with RME, the lowest number of osteoblasts and capillaries in Group 1 (P < .05). New bone formation, fibrous callus formation, distal osteotomy line, proximal osteotomy union and cortex remodelling were observed to be lower in Group 1 and Group 2 than Group 3 (P < .05). There was a statistically significant difference between Group 4 and each of the other groups (P = .000) in the evaluation of the results for bone mineral density, bone volume, bone volume percentage, trabecular thickness and trabecular number. CONCLUSIONS: MPH reduces cellular activity for new bone formation in suture in RME groups. Before performing rapid maxillary expansion in patients using MPH, the use of the drug should be postponed after a multidisciplinary decision process or clinical doses should be lowered.

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).

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.

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.

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.

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.

National clinical guideline for assessment and treatment of ADHD in children and young people: quick guide

Professional observers are independent persons who have in-depth knowledge of both children's normal behaviour and development and of ADHD, and who take a multidisciplinary approach to ADHD in their daily work. The observation must be geared to the specific problem with the child in question

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.
