Aims
Previous studies have already shown early proximal ingrowth, fast osseous integration, and a stable fit of the uncemented Symax hip stem, with excellent clinical and radiographic performance. Aims were to evaluate cumulative revision rates and reasons for revision of the Symax hip stem using Dutch Arthroplasty Register (LROI) data and to assess possible associations between patient characteristics and revision rate of the Symax hip stem.

Patients and methods
All total hip arthroplasties with the uncemented Symax hip stem registered in the LROI between 2007 and 2017 were included (n = 5,013). Kaplan-Meier survival analysis was performed to assess the cumulative 1, 5 and 7-year revision percentages. Cox proportional hazard regression analysis was performed to assess the association between patient and procedural characteristics, and revision arthroplasty of the stem.

Results
Cumulative 1, 5, and 7-year revision rates (with 95% confidence interval (CI)) for revision of any component were 1.5% (CI 1.2%-1.8%), 3.2% (CI 2.7%-3.7%), and 3.8% (CI 3.1%-4.4%) respectively. Cumulative 1, 5, and 7-year stem revision rates of the Symax hip stem were 0.9% (CI 0.6%-1.1%), 1.5% (CI 1.1%-1.9%), and 1.7% (CI 1.3%-2.1%) respectively. Periprosthetic fractures (n = 35) and loosening of the stem (n = 30) were the most common reasons for revision of the stem. Revision of the stem was associated with acute fracture as primary diagnosis (Hazard Ratio (HR) 2.4 (CI 1.3–4.3)), or history of a previous surgery to the affected hip (HR 2.7 (CI 1.4–5.2)).

Conclusion
This population-based registry study shows revision rates for the Symax hip stem comparable to those for best performing uncemented total hip arthroplasties in the Netherlands. Primary diagnosis of an acute fracture, and history of previous surgery on the affected hip, were significantly associated risk factors for revision of the Symax hip stem, and we discourage the use of the Symax hip stem in these patients.
Impulsivity in Parkinson’s disease patients treated with subthalamic nucleus deep brain stimulation—An exploratory study
Authors: Pham U. , Skogseid I. M. , Pripp A. H. , Bøen E. , Toft M. 
Published: March 2021

Background
Deep brain stimulation of the subthalamic nucleus (STN-DBS) is a recognized treatment in Parkinson’s disease (PD). Knowledge is still limited regarding the possible impact of STN-DBS on personality traits and the personality characteristics of PD patients who undergo surgery.

Methods
To assess personality traits in relation to STN-DBS we did an ancillary protocol as part of a prospective randomized study that compared two surgical strategies. Patients were assessed with the Temperament and Character Inventory (TCI), the Urgency, Premeditation, Perseverance and Sensation Seeking impulse behavior scale, the Eysenck Personality Questionnaire (EPQ) and the Toronto Alexithymia Scale preoperatively and after one year of STN-DBS. EPQ and TCI baseline scores were compared with mean scores of healthy reference populations.

Results
After 12-months of STN-DBS, there was a significant decline in Persistence compared to baseline. Preoperatively, the STN-DBS patients had significantly lower Persistence and Self-Transcendence scores, and significantly higher scores on Novelty-Seeking, Self-Directedness, Cooperativeness and on Social Conformity than referenced populations. No difference was found in Neuroticism or Harm-Avoidance scores. The baseline prevalence of alexithymia was low and at 1-year follow-up there was no significant change in alexithymia scores.

Conclusions
We found a higher baseline level of impulsivity in PD patients who underwent STN-DBS. After one year of STN-DBS, our results indicated that the treatment may affect the patients’ personality by increasing certain aspects of impulsivity. There was no effect on alexithymia. The preoperative personality profile of PD patients might influence the outcome of STN-DBS.

Authors: Wlazło Marcin 
Published: March 2021

The article presents the genesis of women’s disability studies as an academic and social activity of women with disabilities who pointed out that their experiences were ignored both in general disability studies and in the feminist discourse. The contemporary aspects of women’s disability studies are presented on the example of discourses on the body, violence against women with disabilities and their economic situation. The aim of the article is to present women’s disability studies in a context that goes beyond the analyses focused on Europe or the United States of America and broadens the area of interest to include the experiences of women with disabilities in the countries of the Global South.
Adalékok a Horthy-korszak büntető jogtudományának történetéhez
Authors: Lehotay Veronika 
Published: March 2021

The aim of the study is to demonstrate the arguments and debates of jurists and the experts of the criminology about equality, liberties in the Horthy era when these issues were challenged by the restrictions of rights, such as the Anti-Jewish laws and the racial policies. In this period the criminal law focused on the personality and the social background of the perpetrator as an influence of anthropological criminology which combines the study of human races and their personal characteristics with the criminal propensity instincts. In the literature of criminal law new issues appeared such as the restriction of rights, deprivation of rights and racial policies as the influences of the Nurnberg Laws in the Third Reich. The jurists in Hungary paid close attention to the jurisdiction in the Third Reich, but they did not set an example for Hungary. According to their arguments, the German way of the racial law in the Hungarian context is not adaptable because its society is too multi-ethnic. This resonates with the opinion of Pál Angyal, who was the leading figure of the criminal law in Hungary. According to his view, criminal law cannot be a tool for racism, but it can be useful in the field of civil law and the state administration. Despite the jurist’s cautious argument, the racial policies appeared in legislation after 1938.

Published: March 2021

Buffelgrass (Cenchrus ciliaris) is widely grown in tropical and sub-tropical arid rangelands around the globe because of its high tolerance to drought and high level of nutrients. In the present study, the seed germination response of 12 buffelgrass genotypes (nine collected accessions and three introduced varieties) was tested to record the various effects of storage duration and temperature treatments on germination. Five constant temperature treatments (15, 20, 25, 30 and 35&deg;C) and two storage durations (12 and 24 months) were used. The studied buffelgrass genotypes responded differently to the different storage durations and temperature regimes, suggesting the importance of genotype assessment under different environments. The highest germination percentages were recorded for genotype BUR-1 at 20&deg;C (45%) after 12 months. No germination occurred after 12 months at low constant temperatures (15&deg;C) for all genotypes except BUR-1, BUR-2 and UIA. Therefore, there is a large genetic variability among buffelgrass genotypes for seed germination, which could permit improvement by selection and breeding.

AbstractOverexcitability is a special characteristic of gifted which lead to a higher level of development. Overexcitability not only has a positive effect, but aslo has a negative effect. The variations in the level and form of overexcitability possessed by gifted raises the question of whether the main attributes of giftedness, namely intelligence and creativity, are predictors of overexcitability itself. This research was conducted to examine the effect of intelligence and creativity on overexcitability. Sample of this study includes 173 students of SMAN 2 Tangerang Selatan. Overexcitability measured by Overexcitability Questionnaire II (OEQ II). OEQ II was adapted based on Indonesian culture. Intellegence measured by Culture Fair Intellegence Test (CFIT). Creativity measured by Tes Kreativitas Figural (TKF). The results of this study indicate that intelligence and creativity together significantly affect overexcitability by 7.9%. However, dimensional analysis show that intelligence and creativity significantly affects sensual, intellectual, and imaginational overexcitability.

A narrative review of the pharmacological, cultural and psychological literature on ibogaine
Authors: Underwood Martie S. , Bright Stephen J. , Les Lancaster B. 
Published: March 2021

AbstractIbogaine is a psychoactive alkaloid contained in the West African plant Tabernanthe iboga. Although preliminary, evidence suggests that ibogaine could be effective in the treatment of certain substance use disorders, specifically opioid use disorder. This narrative review concentrated on the pharmacological, cultural and psychological aspects of ibogaine that contribute to its reputed effectiveness with a specific focus on the ibogaine state of consciousness. Although the exact pharmacological mechanisms for ibogaine are still speculative, the literature highlighted its role as an NMDA antagonist in the effective treatment of substance use disorders. The cultural aspects associated with the use of ibogaine pose questions around the worldview of participants as experienced in the traditional and western contexts, which future research should clarify. From a psychological perspective, the theory that the ibogaine state of consciousness resembles REM sleep is questionable due to evidence that indicated ibogaine supressed REM sleep, and contradictory evidence in relation to learning and memory. The suggested classification of the ibogaine experience as oneirophrenic also seems inadequate as it only describes the first phase of the ibogaine experience. The ibogaine experience does however present characteristics consistent with holotropic states of consciousness, and future research could focus on exploring and potentially classifying the state of consciousness induced by ibogaine as holotropic.

Significance Statement
Kidney transplantation rates and outcomes vary across transplant centers. Some patients may gain an advantage by traveling to a center with characteristics more favorable than those of the center nearest their residence. The authors examined patient and center characteristics associated with longer travel distance and the latter’s association with receipt of kidney transplantation and graft survival in the United States. Patients were more likely to travel farther if they were of non-Black race or if the nearest center had a lower volume of living donor surgeries. Longer travel distance associated with higher likelihood of living donor transplantation but lower likelihood of deceased donor transplantation, and it was weakly associated with higher graft failure risk. These findings provide insights into advantages (or lack thereof) of traveling beyond the nearest center for transplant care.

Background
Transplant candidates may gain an advantage by traveling to receive care at a transplant center that may have more favorable characteristics than their local center. Factors associated with longer travel distance for transplant care and whether the excess travel distance (ETD) is associated with access to transplantation or with graft failure are unknown.

Methods
This study of adults in the United States wait-listed for kidney transplantation in 1995–2015 used ETD, defined as distance a patient traveled beyond the nearest transplant center for initial waiting list registration. We used linear regression to examine patient and center characteristics associated with ETD and Fine–Gray models to examine the association between ETD (modeled as a spline) and time to deceased or living donor transplantation or graft failure.

Results
Of 373,365 patients, 11% had an ETD≥50 miles. Traveling excess distance was more likely among patients who were of non-Black race or those whose nearest transplant center had lower annual living donor transplant volume. At an ETD of 50 miles, we observed a lower likelihood of deceased donor transplantation (subhazard ratio [SHR], 0.85; 95% confidence interval [95% CI], 0.84 to 0.87) but higher likelihood of living donor transplantation (SHR, 1.14; 95% CI, 1.12 to 1.16) compared with those who received care at their nearest center. ETD was weakly associated with higher risk of graft failure.

Conclusions
Patients who travel excess distances for transplant care have better access to living donor but not deceased donor transplantation and slightly higher risk of graft failure. Traveling excess distances is not clearly associated with better outcomes, especially if living donors are unavailable.
Publikum als (bewegte) Masse. Suddenly everywhere is black with people von Marcelo Evelin
Authors: Rossi Regina 
Published: March 2021

Interaktion und Partizipation des Publikums in den performativen Künsten nehmen seit den späten 1990er-Jahren stark zu: Die Performances von LIGNA, Gob Squad, Rimini Protokoll und SIGNA sowie die Museumsarbeiten von Tino Sehgal sind nur einige Beispiele des deutschsprachigen Gegenwartstheaters hierfür. Inszenierungen und Spielarten von Interaktion und Partizipation sind im Feld der Theater- und Tanzwissenschaft mittlerweile gut erforscht. Die Ausnahme hingegen sind systematisch-wissenschaftliche Analysen der Organisation und Dynamik eines Publikums beispielsweise als Gruppe, Gemeinschaft oder Masse. Aus diesem Grund wird in diesem Beitrag eine Option für die Untersuchung eines teilnehmenden Publikums eröffnet, die auf der Beobachtung von Konstellationen, Reaktionen und Bewegung des Publikums der Performance Suddenly everywhere is black with people basiert. Ausgehend von Elias Canettis Überlegungen in Masse und Macht soll die Gruppe der Zuschauenden als Masse betrachtet werden.
Over Exposure – Under Observation. Eine Berner Momentaufnahme zeitgenössischer Partizipation
Authors: Wehrle Annika 
Published: March 2021

Stimme ab, nimm teil, teile Dich mit, sei dabei! Der Ruf nach Partizipation ist heute allgegenwärtig. Sind damit aber auch Räume wirkmächtiger Beteiligung und Entscheidung verbunden, oder handelt es sich um scheindemokratische Inszenierungsstrategien? Wer erhält nach welchen Spielregeln Zugang zu den (politischen) Bühnen der Gegenwart?
Die heutige Landschaft performativer Künste hat sich zu einer Spielwiese ausdifferenzierter Partizipationsformen entwickelt. War das Theater im Laufe seiner langen Geschichte immer schon ein Ort der Teilhabe und Interaktion, wandelten sich mit den politischen Kontexten, den Machtdispositiven und medialen Verschiebungen stets die Rollen, Funktionen und Kommunikationsanordnungen des Publikums. So stehen heutige Künstler_innen vor der Aufgabe, theatrale Partizipation vor der Folie digitalisierter, globalisierter und mobilisierter Lebenswelten neu zu denken und nach Räumen und Beteiligungsformen zu suchen, mittels derer die performativen Künste ihr politisches, diskursives Potenzial entfalten können.
Entlang des assoziationsreichen Bedeutungsspektrums des Begriffs ›overexposure‹, den das internationale Theaterfestival AUAWIRLEBEN in Bern 2017 zum Motto gewählt hat, fragt der Beitrag nach den Wechselwirkungen performativer und gesellschaftlicher Partizipation im 21. Jahrhundert und legt neuralgische Punkte, Widersprüchlichkeiten und Spannungsfelder offen, die eine Reperspektivierung des zeitgenössischen Publikumsbegriffs mit sich bringt.
