Using a combination technique for the assessment of students’ cognitive structures on acid–base chemistry
Authors: Derman Ayşegül , Gunes Figen , Gulacar Ozcan , Eilks Ingo
Published: December 2023

This study aims to determine the cognitive structures of students at different educational levels (8th grade and 12th grade) related to acid–base chemistry. The research was designed as a case study and structured in two stages. The first stage analyzed concepts related to acid–base chemistry and their direction and strength in students’ knowledge structures. The second stage determined the descriptive and structural features of students’ knowledge structures related to acid–base chemistry in a more holistic approach. The study was carried out with a total of 160 students, 80 grade 8th and 80 12th grade students. A word association test (WAT) and the free writing technique (FWT) were used together. In the WAT, ten different frequency ranges were determined forming cognitive structure maps of the students. With high-frequency values on the map, it was found that the number of stimulus and response words decreased but the strength of associations increased. In frequency ranges where the frequency values of associations were low, it was found that the number of stimulus and response words increased and the cognitive structure organization was at the most advanced level compared to other frequency ranges, but the strength of associations was weak. In general, it was observed that there were no bidirectional and cross-associations between the concepts in the cognitive structures of the students about chemistry and that there was a static structure that included one-way associations only. Additionally, the concepts in the cognitive structures of students related to acid–base chemistry were analyzed in terms of their structural characteristics. It was found that, in the cognitive structures of the students there were no associations between many concepts that should be related to each other.

Handwritten and Typed Discourse in People With Aphasia: Reference Data for Sequential Picture Description and Comparison of Performance Across Modality
Authors: Obermeyer Jessica , Edmonds Lisa , Morgan Jodi
Published: December 2023

Purpose:

Writing can be completed by hand or by typing. Increasingly, functional and social activities are completed in the virtual domain, which often requires discourse level writing. Yet, there is a shortage of research on discourse writing in aphasia. The purpose of this study was to provide preliminary reference data for a sequential picture description task in writing by hand and typing for people with aphasia. Additionally, we examined individual modality differences when comparing handwritten and typed discourse.

Method:

Fifteen people with mild–moderate aphasia participated in this study. They completed a sequential picture description task in handwriting and in typing. Discourse samples were coded for Correct Information Units (CIUs) and Complete Utterances. Measures of productivity were also evaluated (e.g., Total Words, Total Utterances). Participants completed a computer use questionnaire regarding their current and premorbid typing and computer use.

Results:

Preliminary reference data are reported. No significant differences were found at the group level for the measures evaluated. At the individual level, there was evidence of a modality effect for seven participants who demonstrated differences in the proportion of CIUs.

Conclusions:

Although preliminary, these findings suggest that, at the group level, the handwritten and typed discourse produced by people with mild–moderate aphasia is similar. However, at the individual level, there is potential for modality differences. Consistent patterns of premorbid computer use, difficulty ratings, and individual differences in writing modes were not identified for the participants who demonstrated a modality effect. However, there was preliminary evidence that poststroke handedness may contribute to modality differences exhibited by some participants, which should be explored in future research. Additionally, these reference data are preliminary and further research is required from a more heterogeneous group of people with aphasia and to better establish assessment practices for discourse writing.
Prevalence of Anxiety as a Variable in Treatment Outcomes for Individuals With Chronic Refractory Cough
Authors: Wright Miranda L. , Slovarp Laurie , Reynolds Jane , Roy Nelson , Okifuji Akiko , Sundar Krishna M. , Barkmeier-Kraemer Julie M.
Published: December 2023

Purpose:

Anxiety is a mental state characterized by an intense sense of tension, worry, or apprehension relative to something adverse that might happen in the future. Anxiety is a known comorbidity in cough patients, yet its prevalence among those with chronic refractory cough (CRC) is unknown. Anxiety is not typically assessed during evaluation for CRC, but treatments for CRC such as neuromodulators and behavioral cough suppression therapy (BCST) may potentially attenuate anxiety. This preliminary study investigates the potential prevalence of anxiety in CRC and its possible role in treatment outcomes.

Method:

CRC patients seen in a specialty clinic at the University of Utah or the University of Montana completed the Leicester Cough Questionnaire (LCQ) pre- and post-BCST treatment. Participants were dichotomized into positive anxiety screen (PAS) and negative anxiety screen (NAS) groups based on presence or absence of documented anxiety within electronic medical records at the University of Utah and based on a Generalized Anxiety Disorder–7 score > 5 at the University of Montana.

Results:

Of the 86 total participants, 37 (43%) were in the PAS group (29 females,
M
age
= 56 ± 13) and 49 (57%) were in the NAS group (36 females,
M
age
= 64 ± 14). Eighty-nine percent of CRC participants with a PAS reported a clinically meaningful improvement in LCQ total score following treatment compared to 65% of NAS participants. Furthermore, mean pre- to posttreatment change scores on the LCQ were significantly greater within the PAS group (
p
= .002, Cohen's
d
= 0.7, indicating a moderate to large effect size).

Conclusion:

This preliminary study suggests that (a) anxiety may be prevalent among those with CRC and (b) those patients who screen positive for anxiety report greater benefit from BCST.

A novel hybrid centralised decentralised framework for electric vehicles coordination
Authors: Verma Praveen , Dasgupta Pallab , Chakraborty Chandan
Published: December 2023

Hybrid Centralised‐Decentralised Electric Vehicle (EV) coordination policy in the urgent charging scenario is presented. First, a robust and complex optimisation problem considering several key features affecting EV coordination is formulated. Then, a solution strategy for the formulated problem is proposed by decomposing the formulated problem into an EV coordination and simple optimisation problem. The decentralised rule‐based EV coordination strategy works on the principle of direct load flattening and utilises practical EV aggregator‐customer interaction, customer behaviour, and temporospatial shifting of the EVs to flatten the load duration curve at the charging station. Then, the centralised optimisation problem is solved to minimise the operation cost, decrease the power loss, and decrease congestion in the grid. A comparison between uncoordinated and coordinated charging in the case study conducted on the IEEE 24 bus system shows that the proposed approach reduces the average EV load by 1283.26 kW/min, average power loss by 2.465 kW/min, and operation cost by 61.99 $/min during the peak hours.
Abundance of strontium in the Galactic globular cluster 47 Tuc
Authors: Kolomiecas E. , Kučinskas A. , Klevas J. , Dobrovolskas V.
Published: December 2023

Aims. We have determined Sr abundance in a sample of 31 red giant branch stars located in the Galactic globular cluster 47 Tuc with the aim to identify potential differences in the Sr abundance between first population (1P, Na-poor) and second population (2P, Na-rich) stars.

Methods. We derived the Na and Sr abundances from the archival spectra obtained with the UVES spectrograph. To do this, we used 1D ATLAS9 model atmospheres and a 1D local thermodynamic equilibrium spectral synthesis method. Particular attention was paid to assessing the potential impact of CN line blending on the obtained Sr abundances. Furthermore, we evaluated the potential influence of convection on the Sr line formation by using 3D hydrodynamical model atmospheres computed with the CO5 BOLD code.

Results. Our results suggest a weak correlation between the abundances of Sr and Na. Together with a similar correlation between the abundances of Zr and Na determined in our previous study, our analysis of Sr suggests that polluters that have enriched 2P stars with light elements may have produced some s-process elements as well. The mean Sr abundance determined in 31 red giant branch stars of 47 Tuc is ⟨[Sr/Fe]⟩ = 0.18 ± 0.08 (the error denotes the standard deviation due to the star-to-star abundance scatter). This value is within the range of the Sr abundance variation that is observed in Galactic field stars of similar metallicity. The mean [Sr/Zr] abundance ratio in our sample stars suggests that the two s-process elements could have been synthesized by either low-mass asymptotic giant branch stars (M = 1 − 4 M⊙) or massive (M = 10 − 20 M⊙) fast-rotating (vrot = 200 − 300 km s−1) stars.
Fast infrared winds during the radio-loud and X-ray obscured stages of the black hole transient GRS 1915+105

Published: December 2023

The black hole transient GRS 1915+105 entered a new phase of activity in 2018, generally characterised by low X-ray and radio fluxes. This phase has only been interrupted by episodes of strong and variable radio emission, where high levels of X-ray absorption local to the source were measured. We present 18 epochs of near-infrared spectroscopy (2018–2023) obtained with GTC/EMIR and VLT/X-shooter, spanning both radio-loud and radio-quiet periods. We demonstrate that radio-loud phases are characterised by strong P-Cygni line profiles, indicative of accretion disc winds with velocities of up to ∼3000 km s−1. This velocity is consistent with those measured in other black hole transients. It is also comparable to the velocity of the X-ray winds detected during the peak outburst phases in GRS 1915+105, reinforcing the idea that massive, multi-phase outflows are characteristic features of the largest and most powerful black hole accretion discs. Conversely, the evolution of the Brγ line profile during the radio-quiet phases follows the expected trend for accretion disc lines in a system that is gradually decreasing its intrinsic luminosity, exhibiting weaker intensities and more pronounced double-peaks.
Tracking active nests in solar-type pulsators: Ensemble starspot modelling of Kepler asteroseismic targets
Authors: Breton S. N. , Lanza A. F. , Messina S.
Published: December 2023

The satellite Planetary Transits and Oscillations of stars (PLATO), due to be launched late 2026, will provide us with an unprecedented sample of light curves of solar-type stars that will exhibit both solar-type oscillations and signatures of activity-induced brightness modulations. Solar-type pulsators only have moderate levels of activity because high levels of activity inhibit oscillations. This means that these targets represent a specific challenge for starspot modelling. In order to assess the possibilities that PLATO will soon open, we wish to characterise the morphology of active regions at the surface of stars for which we also have a detection of solar-like acoustic oscillations. In this context, we report the results of an ensemble starspot modelling analysis of the Sun and ten solar-type pulsators observed by the Kepler satellite. We implement a Bayesian starspot modelling approach based on a continuous-grid model, accounting for the combined starspot and facular contribution to activity-induced brightness modulations. From our analysis, we find that several stars of our sample exhibit clear signatures of stable longitudinal active nests while sharing activity levels and convection versus rotation regimes similar to the solar regime. By searching for modulations in the reconstructed starspot coverage, we found significant periodicities that we identify as possible signatures of cyclic modulations similar to the quasi-biennal oscillation or the Rieger cycle. We can infer the corresponding intensity of the magnetic field at the bottom of the convective envelope based on the hypothesis that internal magneto-Rossby waves acting on the tachocline cause these modulations.
Criteria for the assessment of the influence of atmospheric turbulence on wind turbine noise propagation
Authors: Kayser Bill , Écotière David , Gauvreau Benoit
Published: December 2023

This paper investigates the influence of atmospheric turbulence on the propagation of wind turbine noise using an aeroacoustic source model coupled with a parabolic equation propagation model. Sets of simulations with and without atmospheric turbulence are performed, allowing the determination of a simple formulation that quantifies the uncertainties of the A-weighted sound pressure level (SPL) when the modelling does not account for atmospheric turbulence. For the case study, the results show that atmospheric turbulence has a negligible effect on SPL up to 800 m from the wind turbine, even under upwind conditions. While the conclusions are specific to this case study, the method appears promising for simplifying the calculation of atmospheric turbulence effect in wind turbine noise studies. A freely accessible online application has been developed to present additional results.
The oracle of D-A-Ch – Results of a Delphi Survey for the
development of the evidence- and consensus-based tool “My
Logbook”

Published: December 2023

Objective The present report describes the results of four delphi surveys
conducted within the quality improvement project “My Logbook”
which aims to translate evidence-based standards for psychosocial care in
pediatric oncology into a practical consensus-based tool.

Methods In four consecutive delphi surveys a total of n=153
international, multi-disciplinary experts rated the content, method, and design
of the different booklets of “My Logbook” which a local expert
group had conceptualized. After each survey, the feedback was incorporated, and
the changes were evaluated in a final consensus vote by the quality assurance
panel of the PSAPOH.

Results While some surveys led to a review on a page level, most booklets
as a whole reached the consensus-level of approval. Over the course of the
surveys, any revisions and comments were incorporated in the booklets, and
approval rates increased steadily.

Discussion The delphi surveys ensured the integration of
multi-disciplinary, international expertise, uncovering issues such as language
barriers and the need for a user manual that would not have been evident in
first line . The incorporation of the input led to a continuous improvement of
the tool, reflected in steadily increasing acceptance rates in the consecutive
survey rounds.

Conclusion The incorporation of the expert input as well as the additional
development of a user manual resulted in a final version of the “My
Logbook” apt for the interdisciplinary application in pediatric oncology
in the entire DACH-region.
Kognitive Einschränkungen nach einem Out-of-Hospital Cardiac
Arrest (OHCA)
Authors: Veelenturf J.M. , Passier P.E.C.A. , van Erp S.
Published: December 2023

Einleitung Die Überlebensrate in den Niederlanden bei einem
„Out-of-Hospital Cardiac Arrest“ ist in den letzten Jahrzehnten
gestiegen, was zum Teil auf den Einsatz von Bürgerhelfern und die
Verfügbarkeit von automatischen externen Defibrillatoren (AED)
zurückzuführen ist. Trotz dieser Entwicklungen sind
Hirnverletzungen nach einem OHCA immer noch ein großes und
häufiges Problem. 42–50% der Überlebenden leiden
an kognitiven Problemen, die oft unerkannt bleiben und ihre Alltagsfunktion,
gesellschaftliche Teilhabe und Lebensqualität erheblich
beeinträchtigen.

ZielFrühzeitige Erkennung von kognitiven Problemen bei
OHCA-Patienten während ihres Krankenhausaufenthalts. Dies soll Patienten
und ihren Angehörigen Informationen über mögliche
kognitive Probleme nach einem OHCA und deren Auswirkungen im Alltag
bereitstellen.

Methode Es wurde ein designorientierter Forschungsansatz in Kombination
mit dem Double-Diamond-Modell verwendet. Es handelte sich um einen iterativen
Prozess, der aus mehreren Forschungsphasen besteht. In jeder Forschungsphase
kamen verschiedene Forschungsmethoden zum Einsatz, wie z.B.
Fokusgruppeninterviews mit Pflegefachkräften (N=34) in
Kombination mit einer Post-it-Methode zur Spezifizierung von Wünschen
und Bedürfnissen.

ErgebnisseNeue Prototypen, darunter ein interdisziplinärer Ansatz,
eine Informationsbroschüre zu den Folgen nach einem Herzstillstand und
Schulungen zu kognitiven Problemen nach einem OHCA für das
Pflegepersonal wurden entwickelt und zeigen erste vielversprechende Ergebnisse.
Die Prototypen wurden vom medizinischen Fachpersonal und den Patienten positiv
aufgenommen. Die Schulung des medizinischen Personals führte zu mehr
Aufmerksamkeit für kognitive Probleme und könnte die
frühzeitige Erkennung fördern. Es gab jedoch einige
Herausforderungen, wie die Abstimmung von Empfehlungen zwischen Fachbereichen
und den Zeitpunkt für Konsultationen. Einige Patienten wünschten
sich eine mündliche Erklärung der Informationsbroschüre
durch den Arzt.

Fazit Eine interdisziplinäre Methode zur Erkennung und
Prüfung kognitiver Probleme während des Krankenhausaufenthalts
wurde entwickelt, erfolgreich umgesetzt und durch eine Pilotstudie getestet. Die
begrenzte Stichprobengröße und -dauer der Pilotstudie
könnten die externe Übertragbarkeit der Ergebnisse
einschränken. Trotz dieser Einschränkungen deuten die Ergebnisse
darauf hin, dass die implementierten Prototypen einen vielversprechenden Ansatz
zur Erkennung kognitiver Probleme bei OHCA-Patienten im Krankenhaus darstellen.
Empfehlungen zur Verbesserung der Prototypen, zur endgültigen
Implementierung, zur Sicherung und für Folgeuntersuchungen wurden
spezifiziert.

Neue therapeutische und supportive Optionen beim
Ovarialkarzinom
Authors: Holzhauer Peter
Published: December 2023

Die vorliegende Kasuistik beschreibt der Therapieverlauf einer Patientin mit high
grade serösem Ovarialkarzinom, FIGO IIIB und BRCA1-Mutation und einer
Defizienz der homologen Rekombination. Die Standardtherapie nach aktueller
Leitlinie sieht hier 6 Zyklen Paclitaxel und Carboplatin in Kombination mit
Bevacizumab vor. Neu ist die mittlerweile etablierte Erhaltungstherapie mit
Bevacizumab in Kombination mit dem PARP-Inhibitor Olaparib. Diese
Kombinationstherapie ist indiziert bei den in diesem Fall vorliegenden
genetischen Veränderungen. Das supportive
komplementärmedizinische Nebenwirkungsmanagement fokussiert sich auf die
bei dieser Therapie wesentliche Nebenwirkung, die Chemotherapie-induzierte
Neuropathie (CIPN). Hier kommt mit der Hilotherapy® ein neues
apparatives Kühlungssystem zum Einsatz, dessen Effektivität in
mehreren Studien evaluiert wurde. Ergänzt wird dieser Ansatz durch die
systemische Behandlung mit Endocannabinoiden, antiinflammatorischen
Fettsäuren und alpha-Liponsäure.
Informationen zur reproduktiven Gesundheit in digitalen Medien
Authors: Kubitza Eva , Böhm Maika
Published: December 2023

Einleitung Die Versorgung im Kontext eines Schwangerschaftsabbruchs ist Teil der reproduktiven Gesundheit. Der Zugang zu sachlichen Informationen über medizinische und rechtliche Aspekte und den Ablauf eines Schwangerschaftsabbruchs ist für eine informierte Entscheidungsfindung von zentraler Bedeutung. Das Internet dient als niedrigschwellige und anonyme Informationsquelle für Menschen, die sich über die Gesundheitsleistung Schwangerschaftsabbruch informieren möchten.

Forschungsziele Die Arbeit untersucht, welche deutschsprachigen Websites zum Thema Schwangerschaftsabbruch über eine Google-Suche angezeigt werden und wer die Anbietenden dieser Seiten sind. Darüber hinaus wird analysiert, welche rechtlichen und medizinischen Informationen auf Websites von Schwangerschaftsberatungsstellen und Ärzt*innen gefunden werden.

Methoden Zwischen Juni 2021 und Juli 2023 wurden mittels dreier quantitativer Medieninhaltsanalysen Google-Treffer (n = 124), Beratungsstellen-Websites (n = 319) sowie Websites von Ärzt*innen/medizinischen Einrichtungen (n = 65) analysiert. Für die Datenerhebungen wurden reliabilitätsgeprüfte Codebücher verwendet, die Daten wurden deskriptivstatistisch ausgewertet.

Ergebnisse Bei einer Google-Recherche mittels Suchbegriffen dominieren die Websites von Medienschaffenden, während Seiten von Gesundheitsfachkräften/-organisationen, Schwangerschaftsberatungsstellen sowie politisch bzw. religiös motivierten Akteur*innen im Sinne des sogenannten Lebensschutzes eine nachrangige Rolle spielen. Die Thematisierung des rechtlichen Kontextes von Schwangerschaftsabbrüchen ist abhängig vom Anbietendentyp. Entsprechende Informationen finden sich v. a. auf Websites der Schwangerschaftsberatungsstellen. Medizinische Informationen können vorrangig auf den Seiten von Ärzt*innen/medizinischen Einrichtungen identifiziert werden.

Schlussfolgerung Abhängig vom Anbietendentyp werden unterschiedliche Informationen zum Schwangerschaftsabbruch in den Mittelpunkt gestellt. Die Ergebnisse weisen auf einen Weiterentwicklungsbedarf von Beratungsstellen- bzw. praxiseigenen Websites hin, u. a. damit entsprechende Angebote von Suchmaschinen besser gefunden werden. Insbesondere die digitale Bereitstellung schwangerschaftsabbruchbezogener Informationen durch Fachkräfte kann zu einer Versachlichung und Verbesserung der Informationslandschaft beitragen.

Funktionsprotektiver Verschluss einer urethrokutanen Fistel der prostatischen Harnröhre über einen perinealen Zugang mit Gracilis-Flap
Authors: Reichert Mathias , Stepniewski Adam , Grade Marian , Felmerer Gunther , Trojan Lutz , Mohr Mirjam Naomi
Published: December 2023

Es wird von einem 36-jährigen Patienten berichtet, der beim Miktionieren Urin perianal aus einem kutanen Porus verliert. Nach entsprechender Diagnostik wird die Diagnose einer urethrokutanen Fistel aus der prostatischen Harnröhre unklarer Ätiologie gestellt. Aufgrund des jungen Alters und der sexuellen Aktivität, stellt die chirurgische Therapie eine Herausforderung dar. Über einen perinealen Zugang wird die Fistel isoliert und prostatanah ligiert, ohne die Gefäßnervenbündel zu gefährden. Um einen sicheren Fistelverschluss zu erzielen, wird anschließend ein Gracilis-Flap als Zwischenschicht zwischen Prostatahinterfläche und perkutanem Fistelausgang gelegt. Bis dato ist kein Fall einer erfolgreichen chirurgischen Therapie einer prostatokutanen Urinfistel beschrieben, die funktionserhaltend durchgeführt werden konnte.

Prospective Observational Study
Authors: Prasad Aravind , Rashmi K. G , Sahoo Jayaprakash , Kamalanathan Sadishkumar , Wyawahare Mukta , Anusuya R , Naik Dukhabandhu
Published: December 2023

Background The severe acute respiratory syndrome coronavirus 2 can affect
the hypothalamic-pituitary-gonadal axis (HPG) due to the expression of the
angiotensin-converting enzyme 2 receptor.

Objectives To assess the prevalence of hypogonadism and Sertoli cell
dysfunction in coronavirus disease 2019 (COVID-19) male survivors.

Method Male subjects recovered from acute COVID-19 infection were
prospectively observed. The primary outcomes included the proportion of
hypogonadism, defined biochemically as serum
testosterone<230 ng/dL or CFT
of<6.4 ng/mL if the total testosterone is between
230–320 ng/m. Sertoli cell dysfunction was defined as
inhibin-B level<54.5 pg/mL. Subjects with hypogonadism
were followed up at 12 months to assess the recovery of the HPG axis.

Results Eighty-three subjects aged≥18 years were evaluated at a
median of 120 (±35) days post-recovery. Their mean age was
49.50±12.73 years, and the mean BMI was
26.84±5.62 kg/m2. Low testosterone was
detected in 21 (24.71%) and low inhibin-B was detected in 14
(19.71%) out of 71 subjects at 3 months. Subjects with low testosterone
were younger, with a mean age of 43.29±12.03 years (P-0.08) and higher
BMI (P-0.012). The severity of COVID-19 infection, duration of hospitalization,
and other factors were not significantly associated with low testosterone. At 12
months, 18 out of 21 subjects came for follow-up, of which 9 (50%)
showed persistently low testosterone, suggestive of hypogonadism.

Conclusion Following COVID-19 infection, testosterone levels recovered
over time; however, a significant proportion of subjects had low levels at
12-month follow-up. These findings have long-term implications for the
management of COVID-19 subjects.

Muscles Thickness and Low Back Pain-Related Disability in Amateur Soccer
Players: An Observational Study
Authors: Miñambres-Martín Diego , Antonio Valera-Calero Juan , Martín-Casas Patricia , Varol Umut , Fernandez-de-las-Penas Cesar , Plaza-Manzano Gustavo
Published: December 2023

Objective Although low back pain (LBP) is one of the most common
musculoskeletal disorders, there is limited evidence assessing which factors
contribute LBP severity in amateur athletes. We aimed to analyze relationships
between sociodemographic, clinical, lifestyle and lumbar multifidus (LM) at L4
and L5 levels, rectus abdominis (RA), external and internal obliques (EO and IO)
and transversus abdominis (TrA) muscles thickness assessed with ultrasound
imaging (US) variables with lumbar disability in amateur athletes with LBP and
lumbar disc herniation.

Methods Eighty-two male amateur soccer athletes were analyzed. Demographic
data, internal hip rotation, finger-floor distance, pain intensity, number of
LBP episodes within the last year, metabolic equivalent of tasks for physical
activity, sitting time, muscle thickness and disability caused by LBP were
collected.

Results Pain intensity showed significant associations with LBP
recurrence, disability, sedentarism, trunk and hip flexibility, vigorous
physical activity and TrA, EO and RA muscles thickness (p<0.05).
Similarly, disability was associated with number of LBP episodes, vigorous
activity, sitting time, finger floor distance, and RA, EO and IO muscles
thickness (p<0.05). TrA thickness and internal hip rotation were not
associated with lumbar disability (p>0.05).

Conclusion LBP intensity and pain-related disability were significantly
associated with LBP episodes, vigorous activity, sitting time, finger floor
distance, and thickness of abdominal muscles were associated with pain intensity
and disability. However, lumbar multifidus thickness at rest, ankle dorsiflexion
and walking time were not associated with clinical severity.
