Abstract

Mit dem Tryptophandepletionstest kann kurzfristig die zentralnervöse Serotoninsynthese reduziert werden. Das TRP-LNAA-Ratio dient dabei zur Abschätzung der zentralnervösen Verfügbarkeit von TRP. In der Literatur besteht jedoch weder über die zu verwendenden LNAAs im Nenner des Ratios noch über die genaue Berechnungsmethode Einigkeit. Ziel dieser Arbeit war es, mithilfe von statistischen Methoden die verschiedenen LNAA-Kombinationen sowie die reguläre und die Km-normalisierte Berechnungsmethode zu vergleichen. Dafür wurden die LNAA-Konzentrationen verwendet, die in der dieser Arbeit zugrundeliegenden Studie erhoben wurden. Das Herausarbeiten von Unterschieden und Übereinstimmung, diente dem Zweck, eine Empfehlung für die Verwendung einer bestimmten LNAA-Kombination und einer Berechnungsmethode geben zu können. Die Ergebnisse dieser Arbeit zeigen, dass die Frage, welche Berechnungsmethode zur Bestimmung des TRP-LNAA-Ratios angewandt werden sollte, nicht trivial ist, da die Ratios beider Berechnungsmethoden nur eine sehr geringe Übereinstimmung zeigen. Die Tatsache, dass sich die Ratios unter Verwendung verschiedener LNAA-Kombinationen bei Anwendung der Km-normalisierten Berechnungsmethode kaum unterschieden, lässt die Km-normalisierte Berechnungsmethode gegenüber der regulären robuster erscheinen. Was die zu verwendende LNAA-Kombination anbelangt, wäre anzuraten, dass in zukünftigen Studien eine umfassende LNAA-Kombination auswählt wird, da das Ratio sich so stabiler gegen Ausreißer der einzelnen LNAAs darstellt.

Abstract

Der Bulbus olfactorius (OB) spielt eine wichtige Rolle in der Wahrnehmung von Gerüchen. Das OB-Volumen korreliert mit der Riechfunktion und ist daher ein Biomarker für mehrere neurodegenerative Erkrankungen sowie für Riechstörungen. In mehreren Studien wurde gezeigt, dass eine Abnahme des OB-Volumens mit einer Abnahme der Geruchsempfindlichkeit einhergeht und umgekehrt. Dies bedeutet, dass die Messung des OB-Volumens für verschiedene Diagnose- und Forschungszwecke von großem Interesse ist. Bisher wurden diese Messungen manuell durchgeführt, was mit einem Zeitaufwand von 15-20 Minuten pro Probanden eine sehr langwierige Methode ist, die außerdem zu erheblichen Messungenauigkeiten führt. Dies erschwert die Verarbeitung großer Datensätze sowie den Vergleich verschiedener Studien. Um dieses Problem zu lösen, haben wir einen vollautomatisierten, auf Deep-Learning basierten Algorithmus zur Segmentierung des OB sowie zur Messung dessen Volumens entwickelt und ein einsatzbereites Tool zur Anwendung veröffentlicht. Des Weiteren wurde eine Studie an Patienten mit Mild Cognitive Impairment (MCI) durchgeführt, um den Effekt von Riechtraining auf funktionale und morphologische Veränderungen des OB und des Hippocampus zu untersuchen. Methoden: Wir haben unseren Algorithmus auf vier Datensätzen trainiert und getestet, die jeweils aus T1-gewichteten MRT-Aufnahmen des gesamten Gehirns sowie hochaufgelösten T2-gewichteten Aufnahmen der vorderen Schädelbasis und den entsprechenden klinischen Informationen über das Riechvermögen der Probanden bestehen. Ein Datensatz enthielt Patienten mit gesicherter Anosmie oder Hyposmie (N = 79). Die anderen drei Datensätze enthielten gesunde Probanden (N = 91). Um die Grundwahrheit für die OB-Segmentierung und die Volumenmessung zu erhalten, wurden die Datensätze von zwei erfahrenen wissenschaftlichen Mitarbeitern unabhängig voneinander nach einem einheitlichen Protokoll manuell segmentiert. Verglichen mit dem gesamten Gehirn nimmt der OB ein

Abstract

Magnetic resonance spectroscopy is a powerful, non-invasive, quantitative imaging technique that allows for the measurement of brain metabolites that has demonstrated utility in diagnosing and characterizing a broad range of neurological diseases. Its impact, however, has been limited due to small sample sizes and methodological variability in addition to intrinsic limitations of the method itself such as its sensitivity to motion. The lack of standardization from a data acquisition and data processing perspective makes it difficult to pool multiple studies and/or conduct multisite studies that are necessary for supporting clinically relevant findings. Based on the experience of the ENIGMA MRS work group and a review of the literature, this manuscript provides an overview of the current state of MRS data harmonization. Key factors that need to be taken into consideration when conducting both retrospective and prospective studies are described. These include (1) MRS acquisition issues such as pulse sequence, RF and B0 calibrations, echo time, and SNR; (2) data processing issues such as pre-processing steps, modeling, and quantitation; and (3) biological factors such as voxel location, age, sex, and pathology. Various approaches to MRS data harmonization are then described including meta-analysis, mega-analysis, linear modeling, ComBat and artificial intelligence approaches. The goal is to provide both novice and experienced readers with the necessary knowledge for conducting MRS data harmonization studies.

Abstract

Investigators in the cognitive neurosciences have turned to Big Data to address persistent replication and reliability issues by increasing sample sizes, statistical power, and representativeness of data. While there is tremendous potential to advance science through open data sharing, these efforts unveil a host of new questions about how to integrate data arising from distinct sources and instruments. We focus on the most frequently assessed area of cognition - memory testing - and demonstrate a process for reliable data harmonization across three common measures. We aggregated raw data from 53 studies from around the world which measured at least one of three distinct verbal learning tasks, totaling N = 10,505 healthy and brain-injured individuals. A mega analysis was conducted using empirical bayes harmonization to isolate and remove site effects, followed by linear models which adjusted for common covariates. After corrections, a continuous item response theory (IRT) model estimated each individual subject’s latent verbal learning ability while accounting for item difficulties. Harmonization significantly reduced inter-site variance by 37% while preserving covariate effects. The effects of age, sex, and education on scores were found to be highly consistent across memory tests. IRT methods for equating scores across AVLTs agreed with held-out data of dually-administered tests, and these tools are made available for free online. This work demonstrates that large-scale data sharing and harmonization initiatives can offer opportunities to address reproducibility and integration challenges across the behavioral sciences.

Abstract

Left-right asymmetry is an important organizing feature of the healthy brain that may be altered in schizophrenia, but most studies have used relatively small samples and heterogeneous approaches, resulting in equivocal findings. We carried out the largest case-control study of structural brain asymmetries in schizophrenia, using MRI data from 5,080 affected individuals and 6,015 controls across 46 datasets in the ENIGMA consortium, using a single image analysis protocol. Asymmetry indexes were calculated for global and regional cortical thickness, surface area, and subcortical volume measures. Differences of asymmetry were calculated between affected individuals and controls per dataset, and effect sizes were meta-analyzed across datasets. Small average case-control differences were observed for thickness asymmetries of the rostral anterior cingulate and the middle temporal gyrus, both driven by thinner left-hemispheric cortices in schizophrenia. Analyses of these asymmetries with respect to the use of antipsychotic medication and other clinical variables did not show any significant associations. Assessment of age- and sex-specific effects revealed a stronger average leftward asymmetry of pallidum volume between older cases and controls. Case-control differences in a multivariate context were assessed in a subset of the data (N = 2,029), which revealed that 7% of the variance across all structural asymmetries was explained by case-control status. Subtle case-control differences of brain macro-structural asymmetry may reflect differences at the molecular, cytoarchitectonic or circuit levels that have functional relevance for the disorder. Reduced left middle temporal cortical thickness is consistent with altered left-hemisphere language network organization in schizophrenia.

Abstract

Schizophrenia (SZ) is associated with an increased risk of life-long cognitive impairments, age-related chronic disease, and premature mortality. We investigated evidence for advanced brain ageing in adult SZ patients, and whether this was associated with clinical characteristics in a prospective meta-analytic study conducted by the ENIGMA Schizophrenia Working Group. The study included data from 26 cohorts worldwide, with a total of 2803 SZ patients (mean age 34.2 years; range 18–72 years; 67% male) and 2598 healthy controls (mean age 33.8 years, range 18–73 years, 55% male). Brain-predicted age was individually estimated using a model trained on independent data based on 68 measures of cortical thickness and surface area, 7 subcortical volumes, lateral ventricular volumes and total intracranial volume, all derived from T1-weighted brain magnetic resonance imaging (MRI) scans. Deviations from a healthy brain ageing trajectory were assessed by the difference between brain-predicted age and chronological age (brain-predicted age difference [brain-PAD]). On average, SZ patients showed a higher brain-PAD of +3.55 years (95% CI: 2.91, 4.19; I2 = 57.53%) compared to controls, after adjusting for age, sex and site (Cohen’s d = 0.48). Among SZ patients, brain-PAD was not associated with specific clinical characteristics (age of onset, duration of illness, symptom severity, or antipsychotic use and dose). This large-scale collaborative study suggests advanced structural brain ageing in SZ. Longitudinal studies of SZ and a range of mental and somatic health outcomes will help to further evaluate the clinical implications of increased brain-PAD and its ability to be influenced by interventions.

Abstract

The C-terminal binding protein 2 (CTBP2) gene (translational isoforms: CTBP2-L/S, RIBEYE) had been identified by a cross-trait analysis of genome-wide association studies for anorexia nervosa (AN) and body mass index (BMI). Here, we did a mutation analysis in CTBP2by performing polymerase chain reactions with subsequent Sanger-sequencing to identify variants relevant for AN and body weight regulation and ensued functional studies. Analysis of the coding regions of CTBP2in 462 female patients with AN (acute or recovered), 490 children and adolescents with severe obesity, 445 healthy-lean adult individuals and 168 healthy adult individuals with normal body weight detected 24 variants located in the specific exon of RIBEYE. In the initial analysis, three of these were rare non-synonymous variants (NSVs) detected heterozygously in patients with AN (p.Arg72Trp - rs146900874; p.Val289Met -rs375685611 and p.Gly362Arg - rs202010294). Four NSVs and one heterozygous frameshift variant were exclusively detected in children and adolescents with severe obesity (p.Pro53Ser - rs150867595; p.Gln175ArgfsTer45 - rs141864737; p.Leu310Val - rs769811964; p.Pro397Ala - rs76134089 and p.Pro402Ser - rs113477585). RibeyemRNA was detected in mouse hypothalamus. No effect of fasting or overfeeding on murine hypothalamic Ribeyeexpression was determined. Yet, increased Ribeyeexpression was detected in hypothalami of leptin-treated Lepob/obmice. This increase was not related to reduced food intake and leptin-induced weight loss. We detected rare and frequent variants in the RIBEYEspecific exon in both patients with AN and in children and adolescents with severe obesity. Our data suggest RIBEYEas a relevant gene for weight regulation.

Abstract

Abstract.Objective:The purpose of the present study was the analysis of the association between consumption of candy and fruit gums, diagnosis of attention deficit hyperactivity disorder (ADHD), and behavioural problems. Methods:In total, 1,187 children and adolescents of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) were analyzed. Results:It was observed that children and adolescents with ADHD as compared to healthy controls (HC) reported to consume more frequently and higher amounts of candy and fruit gums and that hyperactivity was associated with frequent candy and fruit gum consumption. Conclusions:Because with the present design no conclusions on causality or directionality of the found associations could be drawn, results are discussed quite broadly in the light of several previously published interpretations, also to serve as a generator for further research. One more innovative speculation is that children and adolescents with ADHD may consume more frequently candy and fruit gums in order i) to compensate for their higher needs of energy resulting from hyperactive behaviour and/or ii) to compensate for the ADHD-typical deficits in the “reward cascade”.

Abstract

Background: The amygdala is a subcortical limbic structure consisting of histologically and functionally distinct subregions. New automated structural magnetic resonance imaging (MRI) segmentation tools facilitate the in vivo study of individual amygdala nuclei in clinical populations such as patients with anorexia nervosa (AN) who show symptoms indicative of limbic dysregulation. This study is the first to investigate amygdala nuclei volumes in AN, their relationships with leptin, a key indicator of AN-related neuroendocrine alterations, and further clinical measures. Methods: T1-weighted MRI scans were subsegmented and multi-stage quality controlled using FreeSurfer. Left/right hemispheric amygdala nuclei volumes were cross-sectionally compared between females with AN (n = 168, 12–29 years) and age-matched healthy females (n = 168) applying general linear models. Associations with plasma leptin, body mass index (BMI), illness duration, and psychiatric symptoms were analyzed via robust linear regression. Results: Globally, most amygdala nuclei volumes in both hemispheres were reduced in AN v. healthy control participants. Importantly, four specific nuclei (accessory basal, cortical, medial nuclei, corticoamygdaloid transition in the rostral-medial amygdala) showed greater volumetric reduction even relative to reductions of whole amygdala and total subcortical gray matter volumes, whereas basal, lateral, and paralaminar nuclei were less reduced. All rostral-medially clustered nuclei were positively associated with leptin in AN independent of BMI. Amygdala nuclei volumes were not associated with illness duration or psychiatric symptom severity in AN. Conclusions: In AN, amygdala nuclei are altered to different degrees. Severe volume loss in rostral-medially clustered nuclei, collectively involved in olfactory/food-related reward processing, may represent a structural correlate of AN-related symptoms. Hypoleptinemia might be linked to rostral-medial amygdala alterations. [ABSTRACT FROM AUTHOR]

Abstract

Objective: The capacity of individuals with anorexia nervosa (AN) to forgo immediate food rewards in their long‐term pursuit of thinness is thought to reflect elevated self‐control and/or abnormal reward sensitivity. Prior research attempted to capture an increased tendency to delay gratification in AN using delay‐discounting tasks that assess how rapidly the subjective value of rewards decreases as a function of time until receipt. However, significant effects were mostly subtle or absent. Here, we tested whether the process leading to such decisions might be altered in AN. Method: We recorded mouse‐cursor movement trajectories leading to the final choice in a computerized delay‐discounting task (238 trials) in 55 acutely underweight females with AN and pairwise age‐matched female healthy controls (HC). We tested for group differences in deviations from a direct choice path, a measure of conflict strength in decision making, and whether group moderated the effect of several predictors of conflict strength (e.g., choice difficulty, consistency). We also explored reaction times and changes in trajectory directions (X‐flips). Results: No group differences in delay‐discounting parameters or movement trajectories were detected. However, the effect of the aforementioned predictors on deviations (and to a lesser extent reaction times) was reduced in AN. Discussion: These findings suggest that while delay discounting and conflict strength in decision making are generally unaltered in AN, conflict strength was more stable across different decisions in the disorder. This might enable individuals with AN to pursue (maladaptive) long‐term body‐weight goals, because particularly conflicting choices may not be experienced as such. Public Significance: The deviations from a direct path of mouse‐cursor movements during a computerized delay‐discounting task varied less in people with anorexia nervosa. Assuming such deviations measure decision conflict, we speculate that this increased stability might help people with anorexia nervosa achieve their long‐term weight goals, as for them the struggle with the decision to eat high‐calorie meals when hungry will be milder, so they would be more likely to skip them.

Abstract

Introduction Longitudinal study is an essential methodology for understanding disease trajectories, treatment effects, symptom changes, and long-term outcomes of affective disorders. Daily self-charting of mood and other illness-related variables is a commonly recommended intervention. With the widespread acceptance of home computers in the early 2000s, automated tools were developed for patient mood charting, such as ChronoRecord, a software validated by patients with bipolar disorder. The purpose of this study was to summarize the daily mood, sleep, and medication data collected with ChronoRecord, and highlight some of the key research findings. Lessons learned from implementing a computerized tool for patient self-reporting are also discussed. Methods After a brief training session, ChronoRecord software for daily mood charting was installed on a home computer and used by 609 patients with affective disorders. Results The mean age of the patients was 40.3±11.8 years, a mean age of onset was 22±11.2 years, and 71.4% were female. Patients were euthymic for 70.8% of days, 15.1% had mild depression, 6.6% had severe depression, 6.6% had hypomania, and 0.8% had mania. Among all mood groups, 22.4% took 1–2 medications, 37.2% took 3–4 medications, 25.7 took 5–6 medications, 11.6% took 7–8 medications, and 3.1% took >8 medications. Conclusion The daily mood charting tool is a useful tool for increasing patient involvement in their care, providing detailed patient data to the physician, and increasing understanding of the course of illness. Longitudinal data from patient mood charting was helpful in both clinical and research settings. [ABSTRACT FROM AUTHOR]

Abstract

The development, maintenance, and factors influencing treatment outcome in anorexia nervosa (AN) continue to be investigated. In this context, the construct of punishment sensitivity (PS) has received increasing attention. Many studies showed that individuals with AN exhibit elevated PS. A recent study by Jonkers et al. (2022) found that individuals with AN who exhibited higher PS prior to the initiation of therapy showed less reduction in eating disorder symptomatology after treatment. Furthermore, a reduction in PS during therapy also appears to be related to a reduction in eating disorder symptomatology (Jonker et al., 2022). In this study we are going to take these findings under test. In addition, the relationship between PS and AN will be extended to include the factors of depressiveness and anxiety. The interaction of PS, depressiveness, anxiety and the therapy outcome in AN will be investigated with an explorative sensitivity analysis.

Abstract

We plan to investigate Myelin Water Fraction (MWF) in the acute state of Anorexia Nervosa (AN). Our study will further the understanding of structural alterations in the brain of patients acutely suffering from anorexia nervosa and possible changes in myelin content in white, cortical and intracortical gray mater areas of the brain. Recent studies suggested decreased intracortical myelin concentration (measured as quantitative T1 values) in AN (Pappaianni et al., 2022) and lower cortical myelin (measured as T1w/T2w ratio) in regions associated with cognitive control (Bischoff-Grethe et al., 2021). We will use a 3D gradient spin echo sequences (GRASE) (Prasloski et al., 2012) to measure MWF in patients acutely suffering from AN and age matched healthy controls.

Abstract

Cognitive effort is generally experienced as aversive and costly (Westbrook & Braver, 2015), but less so by some individuals and many people enjoy challenging mental tasks for their own sake (Inzlicht et al., 2018). In this study, we aim to explore individual differences in the tendency to experience cognitive effort as aversive and costly or pleasurable and rewarding. To this end, we developed a Cognitive Effort Choice Task in which participants repeatedly choose between performing short blocks of a cognitively more effortful task (6 trials of a Stroop color-word task including at least 50% incongruent stimuli) or a less effortful one (6 trials of a Stroop color-word task including only congruent stimuli) for (random) monetary rewards which can be donated to a charity of choice or kept for oneself. The task incorporates aspects of previous experiments of effort-based decision making that have demonstrated that while most people tend to avoid cognitively effortful tasks (e.g. Kool et al., 2010), they also appear to value invested effort because reward-related brain regions show increased activity for rewards given for completing cognitively demanding tasks and they tend to donate them less compared to following less demanding ones (e.g. Hernandez Lallement et al., 2014). We replicated these basic behavioral findings with our Cognitive Effort Choice task in a pilot study in a small online sample (n=50). In the current preregistered study, we intend to more carefully recruit a much larger online sample (n=500) to perform the Cognitive Effort Choice task and complete a range of self-report instruments to help better understand individual differences in effort- and value-based decision making.

Abstract

The problem of poor reproducibility of scientific findings has received much attention over recent years, in a variety of fields including psychology and neuroscience. The problem has been partly attributed to publication bias and unwanted practices such as p‐hacking. Low statistical power in individual studies is also understood to be an important factor. In a recent multisite collaborative study, we mapped brain anatomical left–right asymmetries for regional measures of surface area and cortical thickness, in 99 MRI datasets from around the world, for a total of over 17,000 participants. In the present study, we revisited these hemispheric effects from the perspective of reproducibility. Within each dataset, we considered that an effect had been reproduced when it matched the meta‐analytic effect from the 98 other datasets, in terms of effect direction and significance threshold. In this sense, the results within each dataset were viewed as coming from separate studies in an “ideal publishing environment,” that is, free from selective reporting and p hacking. We found an average reproducibility rate of 63.2% (SD = 22.9%, min = 22.2%, max = 97.0%). As expected, reproducibility was higher for larger effects and in larger datasets. Reproducibility was not obviously related to the age of participants, scanner field strength, FreeSurfer software version, cortical regional measurement reliability, or regional size. These findings constitute an empirical illustration of reproducibility in the absence of publication bias or p hacking, when assessing realistic biological effects in heterogeneous neuroscience data, and given typically‐used sample sizes., Region‐wise effect sizes and reproducibility rates of hemispheric asymmetry effects. In general, effects with higher effect sizes showed higher reproducibility, given the same conditions (e.g., sample size and data heterogeneity).

Abstract

Background: The serotonin (5-HT) hypothesis of anorexia nervosa (AN) posits that individuals predisposed toward or recovered from AN (recAN) have a central nervous hyperserotonergic state and therefore restrict food intake as a means to reduce 5-HT availability (via diminished tryptophan-derived precursor supply) and alleviate associated negative mood states. Importantly, the 5-HT system has also been generally implicated in reward processing, which has also been shown to be altered in AN. Methods: In this double-blind crossover study, 22 individuals recAN and 25 healthy control participants (HC) underwent functional magnetic resonance imaging (fMRI) while performing an established instrumental reward learning paradigm during acute tryptophan depletion (ATD; a dietary intervention that lowers central nervous 5-HT availability) as well as a sham depletion. Results: On a behavioral level, the main effects of reward and ATD were evident, but no group differences were found. fMRI analyses revealed a group × ATD × reward level interaction in the ventral anterior insula during reward anticipation as well as in the medial orbitofrontal cortex during reward consumption. Discussion: The precise pattern of results is suggestive of a 'normalization' of reward-related neural responses during ATD in recAN compared to HC. Our results lend further evidence to the 5-HT hypothesis of AN. Decreasing central nervous 5-HT synthesis and availability during ATD and possibly also by dieting may be a means to normalize 5-HT availability and associated brain processes.

Abstract

Background: We have previously shown increased resting-state functional connectivity (rsFC) in the frontoparietal network (FPN) and the default mode network (DMN) in patients with acute anorexia nervosa. Based on these findings we investigated within-network rsFC in patients recovered from anorexia nervosa to examine whether these abnormalities are a state or trait marker of the disease. To extend the understanding of functional connectivity in patients with anorexia nervosa, we also estimated rsFC between large-scale networks. Methods: Girls and women recovered from anorexia nervosa and pair-wise, age- and sex-matched healthy controls underwent a resting-state fMRI scan. Using independent component analyses (ICA), we isolated the FPN, DMN and salience network. We used standard comparisons as well as a hypothesis-based approach to test the findings of our previous rsFC study in this recovered cohort. Temporal correlations between network time-course pairs were computed to investigate functional network connectivity (FNC). Results: Thirty-one patients recovered from anorexia nervosa and 31 controls participated in our study. Standard group comparisons revealed reduced rsFC between the dorsolateral prefrontal cortex (dlPFC) and the FPN in the recovered group. Using a hypothesis-based approach we extended the previous finding of increased rsFC between the angular gyrus and the FPN in patients recovered from anorexia nervosa. No group differences in FNC were revealed. Limitations: The study design did not allow us to conclude that the difference found in rsFC constitutes a scar effect of the disease. Conclusion: This study suggests that some abnormal rsFC patterns found in patients recovered from anorexia nervosa normalize after long-term weight restoration, while distorted rsFC in the FPN, a network that has been associated with cognitive control, may constitute a trait marker of the disorder., Introduction Anorexia nervosa is a severe psychiatric disorder hallmarked by extreme weight loss (or failure to gain weight during growth) due to relentless control of food intake and has been [...]
