Validation of the maximal cardiopulmonary exercise test in adolescents with major depressive disorder and comparison of cardiorespiratory fitness with sex- and age-related control values.

Endurance training has been shown to be effective in treating adolescents with major depressive disorder (MDD). To integrate endurance training into the therapeutic setting and the adolescents' daily lives, the current performance status of the adolescents should be accurately assessed. This study aims to examine adolescents with MDD concerning exhaustion criteria during a cardiopulmonary exercise test (CPET), as well as to compare the values obtained thereon with sex- and age-related control values.

Pharmacological anti-inflammatory treatment in children and adolescents with depressive symptoms: A systematic-review and meta-analysis.

Growing evidence suggests an association between inflammatory processes and depressive disorders (DD). DD typically emerge during adolescence. Treatment effects of agents with anti-inflammatory properties in youth DD have not been systematically reviewed.

[Movement as a Neuromodulator: How Physical Activity Influences the Physiology of Adolescent Depression].

Movement as a Neuromodulator: How Physical Activity Influences the Physiology of Adolescent Depression In the context of adolescent depression, physical activity is becoming increasingly recognized for its positive effects on neuropathology. Current scientific findings indicate that physical training affects the biological effects of depression during adolescence. Yet the pathophysiology of adolescent depression is not yet fully understood.

Using artificial intelligence-based technologies to detect clinically relevant changes of gross motor function in children with cerebral palsy.

Aim: To compare the 66-item Gross Motor Function Measure (GMFM-66) with the reduced version of the GMFM-66 (rGMFM-66) with respect to the detection of clinically relevant changes in gross motor function in children with cerebral palsy (CP).

Method: The study was a retrospective single centre analysis of children with CP who participated in a rehabilitation programme. Overall, 1352 pairs of GMFM-66 and rGMFM66 measurements with a time interval of 5 to 7 months were available.

Reference centiles of bone mineral density, and body composition of lower limbs in children and adolescents for Hologic DXA Discovery model A.

Regional Dual-energy X-ray absorptiometry (DXA) assessments are useful for patients where whole body measurements are not feasible due to positioning difficulties because of anatomic anomalies (e.g. severe scoliosis) and artifacts due to neuroorthopedic hardware.

Interaction between fat- and muscle development in children and adolescents.

Prevalence of obesity increased noticeably during the last decades. Little is known so far about the association between fat accumulation due to obesity and skeletal muscle mass. The aim of this study was to describe the association between fat mass and muscle mass after adjusting for relevant confounding factors in the National Health and Nutrition Examination Survey (NHANES) study population of children and adolescents.

Contingent negative variation to tactile stimuli - differences in anticipatory and preparatory processes between participants with and without blindness.

People who are blind demonstrate remarkable abilities within the spared senses and compensatory enhancement of cognitive skills, underscored by substantial plastic reorganization in relevant neural areas. However, little is known about whether people with blindness form top-down models of the world on short timescales more efficiently to guide goal-oriented behavior. This electroencephalography study investigates this hypothesis at the neurophysiological level, focusing on contingent negative variation (CNV) as a marker of anticipatory and preparatory processes prior to expected events.

Personality Disorder in Adolescent Patients with Anorexia Nervosa.

Objective: Anorexia nervosa (AN) is a highly debilitating disease which frequently results in chronification and often originates in adolescence. Personality traits have been associated with the onset and maintenance of AN; moreover, study results indicated a worse treatment outcome in patients with AN and comorbid personality disorder (PD). However, research on PD in adolescent AN is scarce.

How Stressful Is Examining Children with Symptoms of Child Abuse?-Measurement of Stress Appraisal (SAM) in German Physicians with Key Expertise in Pediatrics.

Background: Pediatricians frequently feel uncertain about their ability to detect early symptoms of child abuse and how to respond in suspected cases.

Aim: This study investigated the transactional stress model in German pediatricians who experienced imagination stories with a child protection scenario and another potentially stress-triggering scenario.

Methods: A two-part survey was conducted online.

Changes in the TMS-evoked potential N100 in the dorsolateral prefrontal cortex as a function of depression severity in adolescents.

Studies using transcranial magnetic stimulation with simultaneous electroencephalography (TMS-EEG) revealed an imbalance between cortical excitation and inhibition (E/I) in the dorsolateral prefrontal cortex (DLPFC) in depression. As adolescence is a developmental period with an increase in depression prevalence and profound neural changes, it is crucial to study the relationship between depression and cortical excitability in adolescence. We aimed to investigate the cortical excitability of the DLPFC in adolescents with depression and a dependency of the TMS-evoked potential N100 on the depression severity.

Diagnostic Evaluation of the Functional Muscle-Bone Unit in Children With Cerebral Palsy With and Without Low Trauma Fractures.

Children and adolescents with cerebral palsy (CP) are at increased risk of low trauma fractures (LTF) due to low bone mineral content (BMC). The risk of LTFs might be overestimated by only age - and sex adjusted Z-scores for BMC because Z-score based DXA techniques do not take into account other relevant parameters like height, muscle and fat mass. This study aimed to present an update of the functional muscle-bone unit-algorithm (uFMBU-A) to evaluate bone health in children with CP in order to predict the risk of LTF taking into account the parameters sex, age, height, muscle and fat mass.

Differential effects of ergometer-cycling and Whole-Body-Vibration training on serological BDNF and IGF-1 in the treatment of adolescent depression - is there an impact of BDNFp.Val66Met variants?

Background: Pathogenesis and treatment of adolescent depression may be influenced by growth-factors, including brain-derived neurotrophic factor (BDNF) and insulin-like growth factor 1 (IGF-1). We investigated, if treatment response to two different add-on exercise-therapies in juvenile depression, differ in the changes of BDNF and IGF-1 serology. A subgroup analysis for genetic variations in BDNF p.

Immunological Effects of an Add-On Physical Exercise Therapy in Depressed Adolescents and Its Interplay with Depression Severity.

Background: Pro-inflammatory cytokines (PICs) have gained attention in the pathophysiology and treatment of depressive disorders. At the same time, the therapeutic effect of physical activity seems to work via immunomodulatory pathways. The interventional study "Mood Vibes" analyzed the influence of exercise on depression severity (primary endpoint) in depressive adolescents; the influence of PICs on the clinical outcome was analyzed as a secondary endpoint.

Influence of motivational placebo-related factors on the effects of exercise treatment in depressive adolescents.

Recent meta-analyses reveal a moderate effect of physical activity (PA) in the treatment of adolescent depression. However, not only the underlying neurobiological mechanisms, also the influences of placebo-related motivational factors (beliefs and expectancies in sporting, enjoyment and prior sports experiences), are still unclear. Based on the data of our prior study "Mood Vibes", we hypothesized that placebo-inherent factors like positive prior sports experiences and motivational factors, (positive beliefs, expectancies, and enjoyment related to PA), would increase the effects of an add-on exercise-therapy in juvenile depression.

Whole body vibration added to treatment as usual is effective in adolescents with depression: a partly randomized, three-armed clinical trial in inpatients.

There is growing evidence for the effectiveness of exercise in the treatment of adult major depression. With regard to adolescents, clinical trials are scarce. Due to the inherent symptoms of depression (lack of energy, low motivation to exercise), endurance training forms could be too demanding especially in the first weeks of treatment.

A homozygous RAB3GAP2 mutation causes Warburg Micro syndrome.

Warburg Micro syndrome and Martsolf syndrome are clinically overlapping autosomal recessive conditions characterized by congenital cataracts, microphthalmia, postnatal microcephaly, and developmental delay. The neurodevelopmental and ophthalmological phenotype is more severe in Warburg Micro syndrome in which cerebral malformations and severe motor and mental retardation are common. While biallelic loss-of-function mutations in RAB3GAP1 are present in the majority of patients with Warburg Micro syndrome; a hypomorphic homozygous splicing mutation of RAB3GAP2 has been reported in a single family with Martsolf syndrome.
