Context. Most studies devoted to Herbig Ae/Be stars (HAeBes) assume solar metallicity. However, the stellar metallicity, [M/H], is a fundamental parameter that can strongly differ depending on the source and may have important implications for planet formation. It has been proposed that the deficit of refractory elements observed in the surfaces of some HAeBes may be linked to the presence of cavities in their disks and is likely caused by Jovian planets that trap the metal-rich content.
Aims. This work aims to provide a robust test on the previous proposal by analyzing the largest sample of HAeBes characterized by homogeneously derived [M/H] values and stellar and circumstellar properties.
Methods. The spectra of 67 HAeBes, along with their well-known properties drawn from our previous work, have been collected from the ESO Science Archive Facility. Their [M/H] values were derived based on the comparison with Kurucz synthetic models. Statistical analyses were carried out with the aim to test the potential relation between [M/H] and the Meeus group I sources, with spectral energy distributions (SEDs) associated with the presence of cavities potentially carved by giant planets. We critically analyzed the eventual link between [M/H], the SED groups, and the presence of such planets.
Results. Our statistical study robustly confirms that group I sources tend to have a lower [M/H] (typically ~ −0.10) than that of group II HAeBes (~ +0.14). A similar analysis involving SED-based transitional disks, with infrared excess only at wavelengths of ≥2.2 µm, does not reveal such a relation with [M/H]. This result indicates that not all processes capable of creating holes in the inner dust disks end up having an effect on the stellar abundances. The spatial distributions of group I and II sources are similar, at least within the available range of distances to the galactic centre and the galactic plane, for which the observed [M/H] differences are not driven by environmental effects. In addition, group I sources tend to have stronger (sub-) mm continuum emission presumably related to the presence of giant planets. Indeed, literature results indicate that disk substructures probably associated with the presence of giant planets are up to ten times more frequent in group I HAeBes than in group II. Finally, along with the metallicities derived for the whole sample, surface gravities and projected rotational velocities are additional outcomes reported in this work.
Conclusions. We provide indirect evidence to suggest that giant planets are more frequent around group I/low [M/H] stars than around the rest of the HAeBes. However, a direct test of the previous hypothesis requires multiple detections of forming planets in their disks. Such detections have so far been limited to the candidate around the metal depleted ([M/H] = −0.35 ± −0.25) group I HAeBe star AB Aur, which is consistent with our findings.

Zusammenfassung
Hintergrund In der Physiotherapie in Deutschland besteht Bedarf an theoretisch und wissenschaftlich fundierten Implementierungsstrategien zur Förderung des evidenzbasierten Arbeitens (EBP). Bei der Entwicklung solcher Strategien ist es notwendig, die Rahmenbedingungen und Einflussfaktoren im individuellen Kontext zu erfassen und zu berücksichtigen. In diesem Zusammenhang wurde das „science4practice“-Konzept mit dem Ziel entwickelt, die Umsetzung von EBP in physiotherapeutischen Einrichtungen zu fördern.
Ziel Erhebung von Barrieren und Förderfaktoren für die Implementierung des „science4practice“-Konzepts.
Methode Im Rahmen einer Mixed-Methods-Studie wurden qualitative, semistrukturierte Interviews sowie eine quantitative Erhebung anhand eines Online- und Papierfragebogens durchgeführt. An den Interviews nahmen Geschäfts- und Therapieleitungen therapeutischer Einrichtungen sowie Physiotherapeut*innen ohne Leitungsverantwortung teil. An der quantitativen Befragung nahmen Physiotherapeut*innen ohne Leitungsverantwortung teil. Die Daten der Interviews wurden mittels thematischer Inhaltsanalyse ausgewertet. Die Daten der quantitativen Erhebung wurden deskriptiv analysiert.
Ergebnisse Aus den 15 durchgeführten Interviews konnten die mangelnden Fähigkeiten zur Literaturrecherche und -bewertung, negative Erfahrungen mit Veränderungsprozessen sowie unzureichende Zugangsmöglichkeiten zu wissenschaftlicher Literatur als Barrieren abgeleitet werden. Als Förderfaktoren wurden die Unterstützung durch Vorgesetzte sowie die Verfügbarkeit von Ressourcen für die Implementierung des Konzepts identifiziert. Die Umfrageergebnisse von 47 Physiotherapeut*innen ohne Leitungsverantwortung zeigen kumulierte Zustimmungswerte („trifft voll zu“ und „trifft eher zu“) von 83–91 % für die Bereitschaft zur Umsetzung des „science4practice“-Konzepts. Durch die Zusammenführung der quantitativen und qualitativen Daten konnte die Bereitschaft des Teams zur Konzeptumsetzung abschließend als Förderfaktor eingeordnet werden.
Schlussfolgerung Die Studie identifiziert Barrieren und Förderfaktoren aus Sicht der Teilnehmenden mit und ohne Leitungsverantwortung. Einerseits unterstreichen die Daten national und international identifizierte Barrieren wie mangelnde wissenschaftliche Kompetenzen oder unzureichende Zugänge zu wissenschaftlicher Literatur. Andererseits zeigen die Ergebnisse das Potential des Konzepts als EBP-Implementierungsvorhaben in der Physiotherapie in Deutschland. Im nächsten Schritt sollten Studien durchgeführt werden, um die Machbarkeit des Konzepts zu überprüfen.

Published: January 2023

ZusammenfassungAls psychische Erkrankungen sind Autismus-Spektrum-Störungen (ASS) sowohl
in der DSM-V wie auch in der ICD 11 der Gruppe der neuronalen und mentalen
Entwicklungsstörungen eingeordnet. ASS sind Störungen, die
ausnahmslos in der frühen Kindheit beginnen. Eine valide,
frühzeitige Diagnosestellung ist Grundvoraussetzung für die
Bereitstellung angemessener Behandlungs- und Förderleistungen sowie
jeder Versorgungsplanung bezüglich aller relevanter Bereiche wie
Therapie und Frühförderung. Auf Basis eines partizipativ
angelegten wissenschaftlich begleiteten Entwicklungsprozesses zur Verfassung von
Empfehlungen einer ersten Bayerischen Autismus-Strategie in 2018 bis 2021 wurden
Prinzipien, Ziele, Handlungsfelder und Maßnahmen zur Optimierung der
Versorgung von Menschen mit ASS und deren Angehörigen erarbeitet. Dabei
zeigt sich vor allem ein Bedarf an Sensibilisierung zu ASS, der weiteren
Generierung und Bereitstellung von Wissen zu ASS, am Ausbau von fachspezifischen
Angeboten zur Früherkennung, Beratung und Diagnostik sowie ein
flächendeckender Zugang zu Frühförderung und
Therapie.
The Five-substitution Option Enhances Teams’ Running
Performance at High Speed in Football

Published: January 2023

AbstractThe aim of this investigation was to describe how the introduction of the
five-substitution option affected football teams’ running performance. A
comparative analysis was performed in 17 professional football teams for the
2019-2020 (up to three substitutions) vs 2020–2021 (five substitutions
option) seasons in LaLiga. The five-substitution option increased the
number of substitutions (from 2.9±0.1 to 4.2±1.0
substitutions/match, respectively; p<0.01, Effect Size
(ES)=2.11) but it did not change the time selected for the first
substitution (from 57.5±13.0 to 56.2±13.7 min;
p=0.06, ES=0.1). Total running distance was similar between
seasons but running distance at 21.0–23.9 km/h (from
3.0±0.4 to 3.2±0.4 km; p=0.01, ES=0.6)
and at≥24.0 km/h (from 3.0±0.6 to
3.2±0.5 km; p=0.01, ES=0.3) were higher with the
five-substitution option. These increases were associated with a higher distance
covered by starting players (p<0.05) rather than an effect of substitute
players. With the five-substitution option, team coaches increased
the number of substitutions per match which enhanced the possibilities of the
team’s staff to manage players’ physical load. The
five-substitution option allowed also increased running performance
at≥21.0 km/h during the matches.
Why Median Severity and Ordinal Scale Severity Values should not be
used for Injury Burden Results: A Critical Review
Authors: Fuller Colin W 
Published: January 2023

AbstractInjury burden is a composite measure of injury incidence and mean severity; this
parameter has been reported as an output measure from injury surveillance
studies in rugby for over 20 years. The benefits of reporting injury burden
results have, more recently, been recognised in other sports. This wider use of
injury burden as an output measure from injury surveillance studies has,
however, highlighted misunderstandings about how to calculate, present and
interpret injury burden data. The aim of this critical review is to explain why
median severity and ordinal severity scales should not be used to calculate and
report injury burden results in injury surveillance studies. Equations are
presented to show how injury burden results should be calculated, and graphs and
tables are presented to explain the errors that are introduced when median
severity and ordinal scales of severity are used instead of mean severity. This
critical review is intended to highlight the correct procedures for calculating,
reporting and interpreting injury burden results in order to avoid incorrect
results, conclusions and injury prevention recommendations being published.

Published: January 2023

Abstract
Objectives Endoscopic trans-anal colonic decompression (ECD) may be requested in the case of massive colon distension, but evidence regarding success and safety issues remains scarce. The aim of this analysis is to examine the technical success, complications and clinical outcome in a large series of patients undergoing an ECD in various clinical scenarios. A standardized evaluation system was used to identify the pre-interventional risk parameters that might be helpful to guide clinical decision making.
Methods In this single-centre retrospective study, the modified Clavien–Dindo classification (CDC) was applied to assess technical success, complications and clinical outcome of 125 consecutive patients who underwent ECD between 2007 and 2020. Primary endpoint: post interventional 90-day mortality. Secondary endpoints: periprocedural complications (CDC event IV-V) and technical success rate. All Martin criteria for standardized reporting of complications were met. Uni- and multivariable analyses for prediction of complications were carried out.
Results The overall technical success rate was 90%. The periprocedural complication rate was low with 3%. Overall 90-day mortality was 31%. Univariable analyses showed a significant correlation between 90-day mortality and ASA≥4 (p<0.001, odds ratio [OR] 15.33), general anaesthesia (p=0.05, OR 21.42) and elevated serological infection parameters (p 0.028, OR 1.004). The pre-interventional multivariable model identified ASA ≥4 (p <0.001; OR 10.94) as the only independent risk factor.
Conclusions ECD is a safe, easily available, technical feasible, inexpensive and successful tool for colonic decompression in various colonic obstruction scenarios, even in critically ill patients. ASA Score ≥IV can be helpful to identify patients at risk for complications/mortality after ECD.
Revision of Failed Osteochondritis dissecans Surgical Treatment: Case Report
Authors: Maiotti Marco , Rossi Valentina , Armocida Daniele 
Published: January 2023

Abstract
Background Osteochondritis dissecans (OD) is one of the most
common cartilage lesions of the knee. Conservative treatment is recommended if the lesions are
stable with no loose bodies or there are open physes. Surgical intervention is recommended as
the primary treatment in symptomatic adults with unstable chondral lesions or with concomitant
loose bodies. Methods We describe a case of a patient suffering from
OD with a bone lesion in the weight-bearing area of medial femoral condyle. Arthroscopy was
performed and an osteochondral fragment from the medial femoral condyle was observed and two
articular loose bodies were removed. After months, the patient returned with pain and a locked
knee. magnetic resonance imaging (MRI) presented a new unstable chondral flap at the posterior
border of the previous lesion. Surgery was performed again, and at open examination, the
previous OD lesions were covered by regenerative tissue, with a lesion of 3 cm2 at
the inferior medial part of the chondral flap. The peripheral margins were cleaned, and a
subchondral crater was curetted. The subchondral lesion was debrided, and the flap was fixed
with pins and a central bioresorbable screws. Results Revision
surgery with fixation of the chondral flap using bioresorbable pins and screws led to
satisfactory results. Conclusion Open revision surgery allowed us a
more accurate assessment of the OD area to provide an effective fixation of the chondral flap
and in this circumstance, this should have been done after seeing the first MRI.
Pulmonary Sonography – Neonatal Diagnosis Part 2
Authors: Schwarz Simone 
Published: January 2023

AbstractA healthy, air-filled lung can only be visualized by its artifacts, and pathologies of the lung are revealed by changes in these artifacts. Because ultrasound artifacts are predominantly used in pulmonary sonography to assess pathologic processes, the variability of sonographically imageable phenomena is limited. For this reason, different pulmonary diseases may present very similarly in ultrasound. Therefore, a correct interpretation of the findings is only possible in the clinical context, taking into account the age-dependent differential diagnoses.The particular relevance of lung ultrasound in the treatment of neonatal patients results from a close correlation between the extent of sonographically-depictable pathologies and parameters of respiratory insufficiency. This suggests a direct correlation between ultrasound findings and the severity of lung injury. Lung ultrasound thus represents a unique, ubiquitously available, bedside, serial method for monitoring the pulmonary status.
Does Cerebral Oxygenation Change during Peripherally Inserted Central Catheterization in Preterm Infants?
Authors: Ercan Gözde , Imamoglu Ebru Y. , Şahin Özlem , Çolak Derya , Imamoglu Serhat 
Published: January 2023

Objective This study aimed to evaluate the effect of peripherally inserted central venous catheterization on cerebral oxygenation by near-infrared spectroscopy in very low birth weight preterm infants.
Study Design Forty-one preterm infants (gestational age ≤32 weeks and birth weight ≤1,500 g) requiring peripherally inserted central venous catheter were included. Hemodynamic data and cerebral regional oxygen saturation values measured by near-infrared spectroscopy were prospectively collected before (T0) and every 5 minutes for 30 minutes following catheterization. When compared with baseline (T0) values, those values having relative maximum changes in the first 15 minutes and between 15 and 30 minutes were defined as T15 max and T30 max, respectively. Any change of more than a 10% decrease in baseline cerebral rSO2 was considered clinically significant. Additionally, any changes exceeding 20% in heart rate and mean arterial blood pressure values were considered significant. Following catheterization, the time interval to reach the baseline for cerebral regional oxygen saturation was noted.
Results Cerebral regional oxygen saturation values at T15 max and T30 max were found to have decreased significantly in 46 and 22% of patients, respectively. A statistically significant difference was observed between these two time periods (p = 0.002); no significant differences in heart rate, mean arterial blood pressure, or cerebral fractional oxygen extraction values at T15 max and T30 max were observed. All patients reached their baseline cerebral regional oxygen saturation in a median of 25 (15–60) minutes.
Conclusion In very low birth weight preterm infants, monitoring cerebral regional oxygen saturation by near-infrared spectroscopy before and after peripherally inserted central venous catheterization may be useful in clinical practice. The assessment of factors affecting cerebral oxygenation and, in the case of low cerebral oxygenation, implementation of corrective actions before peripherally inserted central catheterization may offer a neuroprotective strategy.

Published: January 2023

Objective Very preterm neonates have high rates of composite outcomes featuring mortality and major morbidities. If the modifiable risk factors could be identified, perhaps the rates could be decreased especially in resource-limited settings.
Study Design We performed a prospective study in a Thai neonatal intensive care unit to identify the risk factors of composite outcomes between 2014 and 2021. The inclusion criterion was neonates who were born in our hospital at a gestational age (GA) of less than 32 weeks. The exclusion criteria were neonates who died in the delivery room or had major congenital anomalies. The composite outcomes were analyzed by multivariable logistic regression with adjusted odds ratios (aORs) and a 95% confidence interval (CI).
Results Over the 8-year study period, 555 very preterm inborn neonates without major birth defects were delivered. The composite outcomes were 29.4% (163/555). The medians (interquartile ranges) of GA and birth weights of the neonates were 29 (27–31) weeks and 1,180 (860–1,475) grams, respectively. By multivariable analysis, GA (aOR: 0.65; 95% CI: 0.55–0.77), small for GA (aOR: 4.93; 95% CI: 1.79–13.58), multifetal gestation (aOR: 2.23; 95% CI: 1.12–4.46), intubation within 24 hours (aOR: 5.39; 95% CI: 1.35–21.64), and severe respiratory distress syndrome (aOR: 5.00; 95% CI: 1.05–23.89) were significantly associated with composite outcomes.
Conclusion Very preterm infants who had a lower GA were small for GA, twins or more, respiratory failure on the first day of life, and severe respiratory distress syndrome were associated with mortality and/or major morbidities.

Published: January 2023

Abstract
Background Over the last two decades, there have been development of approaches that are minimally invasive but achieve maximum effective results with minimal morbidity. The supraorbital keyhole approach (SOKHA) through the transciliary incision is minimally invasive approach that permits effective management of skull base lesions with minimal injury to the soft tissue and surrounding brain.
Aims The aim of this study was to evaluate the efficacy and safety of SOKHA for skull base lesions.
Settings and Design This is a prospective study in a tertiary neurosurgical teaching institute in a metropolitan city.
Materials and Methods Twenty-one patients of various pathology were operated using the SOKHA through the “eye-brow incision.” The pathologies included pituitary adenoma, craniopharyngioma, epidermoid, tuberculum sella, and planum sphenoidale meningioma. The authors describe in detail the surgical approach employed by them for these various pathologies.
Results All neoplastic lesions in this series could be addressed effectively with near total or total excision. No fresh postoperative deficits were noted except a case who developed ipsilateral anterior cerebral artery infarction that resulted in lower limb weakness. One patient developed postoperative abscess requiring surgical excision. At follow-up, all patients revealed a cosmetic scar hidden by the eye brow.
Conclusion The SOKHA is an effective minimally invasive procedure with proven safety for the management of anterior, selected middle skull base lesions and to provide excellent cosmesis with minimal trauma to the adjacent brain. The authors, however, feel that it is technically demanding and surgeons should employ a stepwise progression from simple to more complex lesions.
A New Repair Technique in Pronator Quadratus in Management of Distal Radius Fracture: Comparison with Primary Repair and Unrepaired Techniques
Authors: Ayik Ömer , Bayram Serkan , Altan Murat , Engin Muhammed Çağatay 
Published: January 2023

Abstract
Objective We aimed to compare the functional and clinical results between our new repair technique in the groups with and without pronator quadratus (PQ) repair in distal radius fractures treated with plate fixation using the volar approach.
Methods The medical records of patients who underwent open reduction and volar plate fixation due to distal radius fracture between 2018 and 2020 were studied. In group A, PQ cannot be sutured or tension may occur, the intact radial fascia of the deep anterior fascia (DAF) was placed under the flexors toward the PQ and it was sutured with a 3-0 slow-absorbable monofilament suture to DAF. In group B, no repair was performed. In group C, PQ was sutured with traditional method. Range of motion (ROM) of wrist and handgrip strengths were measured at final examination. Pain was assessed with Visual Analogue Score (VAS), and functional status was evaluated with Quick - Disabilities of the Arm, Shoulder, and Hand (DASH). Complications which included tendinopathy, neuritis, tendon rupture due to plate irritation, implant failure, and malunion were also compared.
Results Seventy-seven patients (group A, 21, group B, 24, group C, 32 patients) were included in the final follow-up examination who met our inclusion criteria. Among the clinical, functional, and radiological results such as ROM, VAS, DASH, grip strength, and complications in the all group at a mean postoperative of 16.6 months no significant difference was observed.
Conclusion Although there was no significant difference between the groups in this study, we think that covering the plate may prevent long-term complications.
