Misjudgement of One’s Own Performance? Exploring Attention Deficit (Hyperactivity) Disorder (ADHD) and Individual Difference in Complex Music and Foreign Language Perception
In previous research, we detected that children and adolescents who were diagnosed
with ADHD showed deficits in both complex auditory processing of musical stimuli and in musical
performance when compared to controls. In this study, we were interested in whether we could detect
similar or distinct findings when we use foreign speech perception tasks. Therefore, we recruited
musically naĂŻve participants (n = 25), music-educated participants (n = 25) and participants diagnosed
with ADHD (n = 25) who were assessed for their short-term memory (STM) capacity and the ability
to discriminate music and speech stimuli and we collected self-ratings of the participants’ music
and language performances. As expected, we found that young adults with ADHD show deficits in
the perception of complex music and difficult speech perception stimuli. We also found that STM
capacity was not impaired in young adults with ADHD and may not persist into young adulthood.
In addition, subjective self-estimation about the participants’ language and music performances
revealed that the ADHD group overestimated their performance competence relatively compared
to both control groups. As a result, the findings of our study suggest that individuals diagnosed
with ADHD require a special training program that not only focuses on improving performance in
perceptual skills of music and language but also requires metacognitive training to develop realistic
self-assessment skills
Prospective, open, multi-centre phase I/II trial to assess safety and efficacy of neoadjuvant radiochemotherapy with docetaxel and oxaliplatin in patients with adenocarcinoma of the oesophagogastric junction
Background: This phase I/II-trial assessed the dose-limiting toxicities (DLT) and maximum tolerated dose (MTD) of neoadjuvant radiochemotherapy (RCT) with docetaxel and oxaliplatin in patients with locally advanced adenocarcinoma of the oesophagogastric junction.
Methods: Patients received neoadjuvant radiotherapy (50.4 Gy) together with weekly docetaxel (20 mg/m2 at dose level (DL) 1 and 2, 25 mg/m2 at DL 3) and oxaliplatin (40 mg/m2 at DL 1, 50 mg/m2 at DL 2 and 3) over 5 weeks. The primary endpoint was the DLT and the MTD of the RCT regimen. Secondary endpoints included overall response rate (ORR) and progression-free survival (PFS).
Results: A total of 24 patients were included. Four patients were treated at DL 1, 13 patients at DL 2 and 7 patients at DL 3. The MTD of the RCT was considered DL 2 with docetaxel 20 mg/m2 and oxaliplatin 50 mg/m2. Objective response (CR/PR) was observed in 32% (7/22) of patients. Eighteen patients (75%) underwent surgery after RCT. The median PFS for all patients (n = 24) was 6.5 months. The median overall survival for all patients (n = 24) was 16.3 months. Patients treated at DL 2 had a median overall survival of 29.5 months.
Conclusion: Neoadjuvant RCT with docetaxel 20 mg/m2 and oxaliplatin 50 mg/m2 was effective and showed a good toxicity profile. Future studies should consider the addition of targeted therapies to current neoadjuvant therapy regimens to further improve the outcome of patients with advanced cancer of the oesophagogastric junction.

Musical Performance in Adolescents with ADHD, ADD and Dyslexia—Behavioral and Neurophysiological Aspects
Research has shown that dyslexia and attention deficit (hyperactivity) disorder (AD(H)D)
are characterized by specific neuroanatomical and neurofunctional differences in the auditory cortex.
These neurofunctional characteristics in children with ADHD, ADD and dyslexia are linked to
distinct differences in music perception. Group-specific differences in the musical performance of
patients with ADHD, ADD and dyslexia have not been investigated in detail so far. We investigated
the musical performance and neurophysiological correlates of 21 adolescents with dyslexia, 19
with ADHD, 28 with ADD and 28 age-matched, unaffected controls using a music performance
assessment scale and magnetoencephalography (MEG). Musical experts independently assessed
pitch and rhythmic accuracy, intonation, improvisation skills and musical expression. Compared
to dyslexic adolescents, controls as well as adolescents with ADHD and ADD performed better in
rhythmic reproduction, rhythmic improvisation and musical expression. Controls were significantly
better in rhythmic reproduction than adolescents with ADD and scored higher in rhythmic and pitch
improvisation than adolescents with ADHD. Adolescents with ADD and controls scored better in
pitch reproduction than dyslexic adolescents. In pitch improvisation, the ADD group performed
better than the ADHD group, and controls scored better than dyslexic adolescents. Discriminant
analysis revealed that rhythmic improvisation and musical expression discriminate the dyslexic
group from controls and adolescents with ADHD and ADD. A second discriminant analysis based on
MEG variables showed that absolute P1 latency asynchrony |R-L| distinguishes the control group
from the disorder groups best, while P1 and N1 latencies averaged across hemispheres separate the
control, ADD and ADHD groups from the dyslexic group. Furthermore, rhythmic improvisation was
negatively correlated with auditory-evoked P1 and N1 latencies, pointing in the following direction:
the earlier the P1 and N1 latencies (mean), the better the rhythmic improvisation. These findings
provide novel insight into the differences between music processing and performance in adolescents
with and without neurodevelopmental disorders. A better understanding of these differences may
help to develop tailored preventions or therapeutic interventions
Mental Health and Health-Related Quality of Life in German Adolescents after the Third Wave of the COVID-19 Pandemic
Evaluations after the first and second waves of the COVID-19 pandemic in Germany
showed an increase in mental health problems and a reduction in health-related quality of life
(HRQoL). The aim of the study was to assess those aspects after the third wave of COVID-19 in
adolescents who decided to receive a vaccination. In students aged 12–17 years recruited from
schools in one German region, mental health (by the strengths and difficulties questionnaire, SDQ)
and HRQoL (by KIDSCREEN-10) were assessed by both a self- and parental report. Data from
1412 adolescents (mean age 14.3 years, SD = 1.64) and 908 parents were collected. The mean self reported HRQoL was T = 53.7 (SD = 11.2), significantly higher in boys than in girls and higher in
younger (12–14 years) than in older (15–17 years) adolescents. In total, 18.7% of adolescents reported
clinically relevant psychological symptoms, especially peer problems (23.5%), emotional problems
(17.4%), and hyperactivity (17.1%). Comparing the present data to evaluations after the first and
second waves of COVID-19, adolescents rated a higher HRQoL and reported less mental health
problems after the third wave. After 1.5 years of living with the pandemic, adolescents have adapted
to the changes in everyday life. Further, the relaxation of restrictions, better school organization, and
the prospect of the vaccination may have increased optimism, wellbeing, and contentment, leading
to declining but still alarming rates of psychological symptoms
Motivations for Adolescent COVID-19 Vaccination: A Comparative Study of Adolescent and Caregiver Perspectives in Germany
Given the crucial role of vaccination in halting the COVID-19 pandemic, it is imperative to
understand the factors that motivate adolescents to get vaccinated. We surveyed adolescents and
their accompanying guardians scheduled to receive a COVID-19 vaccination (Comirnaty) in an urban
region in Germany in mid-2021 regarding their motivation for getting vaccinated and collected data
on their sociodemographic characteristics, medical history, vaccination status, and any history of
COVID-19 infection in the family. We also queried information strategies related to the SARS-CoV-2
pandemic. Motivations for getting vaccinated were similar among adolescents and their parents.
The primary reasons for vaccination were protection against SARS-CoV-2-related illness and gaining
access to leisure facilities. This was not influenced by gender, health status, migration background, or
the presence of chronic or acute diseases. The percentage of parents who had received SARS-CoV-2
immunization and the proportion of parents with a high level of education were higher among study
participants than in the general population. Adolescents were especially willing to be vaccinated
if they came from a better educational environment and had a high vaccination rate in the family.
Emphasizing the importance of vaccination among all segments of the population and removing
barriers to vaccines may lead to an ameliorated acceptance of COVID-19 vaccines
Problematic Internet Use among Adolescents 18 Months after the Onset of the COVID-19 Pandemic
Studies in recent years and especially since the beginning of the COVID-19 pandemic have
shown a significant increase in the problematic use of computer games and social media. Adolescents
having difficulties in regulating their unpleasant emotions are especially prone to Problematic Internet
Use (PIU), which is why emotion dysregulation has been considered a risk factor for PIU. The aim of
the present study was to assess problematic internet use (PIU) in adolescents after the third wave
(nearly 1.5 years after the onset in Europe) of the COVID-19 pandemic. In the German region of
Siegen-Wittgenstein, all students 12 years and older from secondary-level schools, vocational schools
and universities were offered a prioritized vaccination in August 2021 with an approved vaccine
against COVID-19. In this context, the participants filled out the Short Compulsive Internet Use
Scale (SCIUS) and two additional items to capture a possible change in digital media usage time
and regulation of negative affect due to the COVID-19 pandemic. A multiple regression analysis
was performed to identify predictors of PIU. The original sample consisted of 1477 participants,
and after excluding invalid cases the final sample size amounted to 1268 adolescents aged 12–17
(x = 14.37 years, SD = 1.64). The average prevalence of PIU was 43.69%. Gender, age, digital media
usage time and the intensity of negative emotions during the COVID-19 pandemic were all found to
be significant predictors of PIU: female gender, increasing age, longer digital media usage time and
higher intensity of negative emotions during the COVID-19 pandemic were associated with higher
SCIUS total scores. This study found a very high prevalence of PIU among 12- to 17-year-olds for the
period after the third wave of the COVID-19 pandemic, which has increased significantly compared
to pre-pandemic prevalence rates. PIU is emerging as a serious problem among young people in
the pandemic. Besides gender and age, pandemic-associated time of digital media use and emotion
regulation have an impact on PIU, which provides starting points for preventive interventions
Navigating the Future of Organisational Health Services Research in Germany and beyond:a Position Paper
Background Recent analyses have shown that in health services research in Germany, healthcare organisations are often considered primarily as a study setting, without fully taking their complex organisational nature into account, neither theoretically nor methodologically. Therefore, an initiative was launched to analyse the state of Organisational Health Services Research (OHSR) in Germany and to develop a strategic framework and road map to guide future efforts in the field. This paper summarizes positions that have been jointly developed by consulting experts from the interdisciplinary and international scientific community.Methods In July 2023, a scoping workshop over the course of three days was held with 32 (inter)national experts from different research fields centred around OHSR topics using interactive workshop methods. Participants discussed their perspectives on OHSR, analysed current challenges in OHSR in Germany and developed key positions for the field’s development.Results The seven agreed-upon key positions addressed conceptual and strategic aspects. There was consensus that the field required the development of a research agenda that can guide future efforts. On a conceptual level, the need to address challenges in terms of interdisciplinarity, terminology, organisation(s) as research subjects, international comparative research and utilisation of organisational theory was recognized. On a strategic level, requirements with regard to teaching, promotion of interdisciplinary and international collaboration, suitable funding opportunities and participatory research were identified.Conclusions This position paper seeks to serve as a framework to support further development of OHSR in Germany and as a guide for researchers and funding organisations on how to move OHSR forward. Some of the challenges discussed for German OHSR are equally present in other countries. Thus, this position paper can be used to initiate fruitful discussions in other countries
Measurement report : Introduction to the HyICE-2018 campaign for measurements of ice-nucleating particles and instrument inter-comparison in the Hyytiala boreal forest
The formation of ice particles in Earth's atmosphere strongly influences the dynamics and optical properties of clouds and their impacts on the climate system. Ice formation in clouds is often triggered heterogeneously by ice-nucleating particles (INPs) that represent a very low number of particles in the atmosphere. To date, many sources of INPs, such as mineral and soil dust, have been investigated and identified in the low and mid latitudes. Although less is known about the sources of ice nucleation at high latitudes, efforts have been made to identify the sources of INPs in the Arctic and boreal environments. In this study, we investigate the INP emission potential from high-latitude boreal forests in the mixed-phase cloud regime. We introduce the HyICE-2018 measurement campaign conducted in the boreal forest of Hyytiala, Finland, between February and June 2018. The campaign utilized the infrastructure of the Station for Measuring Ecosystem-Atmosphere Relations (SMEAR) II, with additional INP instruments, including the Portable Ice Nucleation Chamber I and II (PINC and PINCii), the SPectrometer for Ice Nuclei (SPIN), the Portable Ice Nucleation Experiment (PINE), the Ice Nucleation SpEctrometer of the Karlsruhe Institute of Technology (INSEKT) and the Microlitre Nucleation by Immersed Particle Instrument (mu L-NIPI), used to quantify the INP concentrations and sources in the boreal environment. In this contribution, we describe the measurement infrastructure and operating procedures during HyICE-2018, and we report results from specific time periods where INP instruments were run in parallel for inter-comparison purposes. Our results show that the suite of instruments deployed during HyICE-2018 reports consistent results and therefore lays the foundation for forthcoming results to be considered holistically. In addition, we compare measured INP concentrations to INP parameterizations, and we observe good agreement with the Tobo et al. (2013) parameterization developed from measurements conducted in a ponderosa pine forest ecosystem in Colorado, USA.Peer reviewe
