Published: October 2023

AimsThe aim of this study was to evaluate medium- to long-term outcomes and complications of the Stanmore Modular Individualised Lower Extremity System (SMILES) rotating hinge implant in revision total knee arthroplasty (rTKA) at a tertiary unit. It is hypothesized that this fully cemented construct leads to satisfactory clinical outcomes.MethodsA retrospective consecutive study of all patients who underwent a rTKA using the fully cemented SMILES rotating hinge prosthesis between 2005 to 2018. Outcome measures included aseptic loosening, reoperations, revision for any cause, complications, and survivorship. Patients and implant survivorship data were identified through both prospectively collected local hospital electronic databases and linked data from the National Joint Registry/NHS Personal Demographic Service. Kaplan-Meier survival analysis was used at ten years.ResultsOverall, 69 consecutive patients (69 knees) were included with a median age of 78 years (interquartile range 69 to 84), and there were 46 females (66.7%). Indications were septic revisions in 26 (37.7%), and aseptic aetiology in the remining 43 (62.3%). The mean follow-up was 9.7 years (4 to 18), and the overall complication was rate was 7.24%, all with patellofemoral complications. Failure rate with ‘any cause revision’ was 5.8%. There was one case of aseptic loosening of the femoral component. At ten years, 17/69 patients (24.63%) had died, and implant survivorship was 92.2%.ConclusionIn our experience, the SMILES rotating hinge prosthesis achieves satisfactory long-term outcomes with ten-year implant survivorship of 92.2% and a patellofemoral complication rate of 7.24%.Cite this article: Bone Jt Open 2023;4(10):776–781.

Published: October 2023

Introduction
Melioidosis is a deadly endemic disease in northern Australia and Southeast Asia, including Sabah, Malaysia, which is caused by the bacterium Burkholderia pseudomallei. It contributes to high fatality rates, mainly due to misdiagnosis leading to the wrong treatment being administered to the patients. Local epidemiology and data on clinical features could assist clinicians during diagnosis and treatment. However, these details are still scarce, particularly in Sabah.

Methods
A retrospective study of 246 culture-confirmed melioidosis cases in Queen Elizabeth Hospital, Sabah, Malaysia was performed between 2016 and 2018. The epidemiological data and clinical and laboratory findings were extracted and analysed.

Results
The annual incidence of culture-confirmed melioidosis cases was estimated to be 4.97 per 100,000 people. The mean age of the patients was 50±15 years. Males and members of the Kadazan-Dusun ethnic group accounted for the majority of the melioidosis cases. The odds ratio analysis indicated that bacteraemic melioidosis in this region was significantly associated with fever (76%), and patients having at least one underlying illness (43%), including diabetes mellitus (32%). Sixty-eight patients (28%) succumbed to melioidosis. Contrary to what is known regarding factors that promote bacteraemic melioidosis, neither patients with fever nor patients with at least one comorbid disease, including diabetes mellitus, were significantly associated with death from melioidosis. There was no statistically significant difference between patients without comorbidities (24, 27%) and those with at least one comorbid disease (26, 25%), including diabetes mellitus (18, 23%). The odds ratios indicate that melioidosis mortality in this region is related to patients showing respiratory organ-associated symptoms (29%), bacteraemia (30%), and septic shock (47%). Burkholderia pseudomallei isolates in this study were highly susceptible to ceftazidime (100%), imipenem (100%), and trimethoprim-sulfamethoxazole (98%).

Conclusions
Information obtained from this study can be used by clinicians to recognise individuals with the highest risk of acquiring melioidosis, estimate an accurate prognosis, and provide effective treatment for melioidosis patients to reduce death from melioidosis.

Published: October 2023

Objective
To examine the contribution of variation in sex hormone excretion to mood and behavioral changes in adolescent females and males.

Design
Prospective, longitudinal observational cohort study.

Methods
Participants were 342 volunteers aged 10–12 years living in rural Australia. Urinary estradiol and testosterone levels measured by liquid chromatography-mass spectrometry were obtained at three-month intervals for three years. Integrated measures (area-under-curve) of urinary steroid excretion summarised as absolute and variability during each 12-month period of the study. Psychosocial data were gathered annually with the primary outcome of depressive symptomatology. Secondary outcomes were the other subscales of the Youth Self-Report, impulsive-aggression, sleep habits, and self-harm.

Results
277 (158 male) participants contributed data over the full duration of the study and could be included in the analyses. In females, analyses of absolute urine hormone levels found no relationship between estradiol and any outcome, but higher testosterone was significantly associated with depression and poorer sleep. Greater variability of both urine estradiol and testosterone was associated with lower total psychopathology, anxious/depressed and social problems scores. Greater variability in urine estradiol was associated with lower attention problems and impulsive aggression in females. In males, higher testosterone and estradiol levels were associated with rule-breaking, and poorer sleep, and no associations were found for gonadal hormone variability for males.

Conclusions
Longitudinal measurement of both iso-sexual and contra-sexual gonadal hormones contributes to a more nuanced view of the impact of sex steroids on mood and behavior in adolescents. These findings may enlighten the understanding of the impact of sex steroids during normal male and female puberty with implications for hormone replacement therapies as well as management of common mood and behavioral problems.

Exploring Nurses' Perceptions of Disaster Preparedness Competencies
Authors: Winarti Wiwin , Gracya Naomi 
Published: October 2023

Background: Indonesia frequently experiences natural disasters, underscoring the importance of nursing competencies in disaster preparedness. Nevertheless, especially among general nurses, the factors shaping these competencies are not well understood.Purpose: This study aimed to explore Indonesian nurses’ perceptions of disaster preparedness competencies and compare these perceptions across distinct characteristics.Methods: Adopting a cross-sectional design, 230 nurses from all wards of a public hospital in Jakarta Province were selected via quota sampling. The Nurses’ Perceptions of Disaster Core Competencies Scale (NPDCC) questionnaire was utilized to assess nurses’ perceptions of competencies across five domains. The study employed Chi-square, Fisher’s exact, and Likelihood ratio tests, followed by backward (likelihood ratio) multiple logistic regression, to analyze the relationship between nurses’ characteristics and their perception of disaster preparedness competencies.Results: Results indicated that 51.7% of nurses perceived their disaster competencies as high, with an average score of 175.84(25.017). Further analysis revealed that nurses’ perceptions of these competencies were influenced by education (p=0.002), disaster simulation experience (p=0.036), and awareness of hospital disaster plans (p=0.012), with Nagelkerke’s R2=0.140. Nurses with a diploma qualification were 2.569 times more likely to perceive their skills as lower. Lack of simulation experience and unawareness of the plan further diminished perceived competencies, with ORs of 2.050 and 5.420, respectively.Conclusion: While education, disaster simulation experience, and plan awareness are crucial for nurses’ perceptions of disaster competencies, enhancing other supportive factors is also vital. This study recommends that hospitals increase educational opportunities, emphasizing regular disaster simulations and granting better access to disaster plans, to bolster nurses’ disaster preparedness competencies.

Open Government und die Teilnahme Deutschlands an der Open Government Partnership
Authors: Rack Oliver 
Published: October 2023

Zusammenfassung
Open Government ist mehr als Beteiligung und Transparenz. Es ist eine Reaktion und eine Proaktion im Zuge der veränderten informationellen Machtverhältnisse durch Technologie, insbesondere durch das World Wide Web. Open Government schafft emanzipatorische Informationsinfrastrukturen, mehr Evidenz im Diskurs und mehr Verbindlichkeit sowie Kontinuität durch intersektorale und Ebenen übergreifenden Zusammenarbeit und Co-Kreation. Open Government ist Teil einer systematischen Grundlage für eine Aufsicht der Öffentlichkeit in einer globalen und offenen Governance aus Berichtswesen, Evaluation und Verbindlichkeitsmechanismen. Die Open Government Partnership bietet einen solchen globalen Verbindlichkeitsmechanismus zur Stärkung von Open Government. OGP ist somit ein Schlüssel-Mechanismus, an dem Deutschland seit 2016 teilnimmt. Obwohl Deutschland durch eine lange Tradition der Partizipation eigentlich gute Voraussetzungen im OGP-Mechanismus hat, liegt es hinter den Erwartungen, auch im internationalen Vergleich. Dabei könnte es insbesondere im Bereich der Multilevel-Governance von Open Government Rollenmodell werden.
Don’t Look Up: House Prices in Emerging Europe
Authors: Cevik Serhan , Naik Sadhna 
Published: October 2023

Abstract
This paper investigates how housing prices respond to economic, financial and demographic conditions in emerging markets in Europe. We use quarterly data covering 10 countries over the period 1998–2022 and implement a panel quantile regression approach to obtain a granular analysis of real estate markets. Overall, economic, financial and demographic developments explain real house price growth in emerging Europe, with income growth having the most significant impact. Quantile regression estimations show that income growth matters more for higher quantiles of the property market. We also find that an increase in short-term or long-term interest rates has a price-dampening impact, indicating that a higher cost of borrowing is associated with lower real house price growth. These results indicate that the downturn in house prices could deepen with the looming economic recession and soaring interest rates.

Published: October 2023

Abstract
This is a retrospective study of patients admitted to Jackson Hospital, Montgomery, Alabama, with a diagnosis of COVID-19 from January 1, 2021, to February 15, 2022. The independent variables used in the models were patient sex, age, race, BMI category, daily D-dimer categories, categories of anticoagulation doses, bleeding episodes, and vaccination status. The three different categories of anticoagulation doses were considered for the purpose of the study which were Enoxaparin 40 mg daily vs Enoxaparin 80 mg daily vs Enoxaparin 1 mg/kg or equivalent daily. The study reviewed a total of 100 hospitalized patients. Intermediate-dose anticoagulation was found to be the optimal dose as only 14% patients died compared to a 36 and 50% death rate among those treated with low-dose and high-dose anticoagulation, respectively. The multivariate linear regression model predicting patient oxygen requirements revealed D-dimer and bleeding status to be statistically significant predictors with a p value of <0.01. For the patients who had a D-dimer value ≥2 µg/mL, the oxygenation requirement was predicted to be 31 L higher than those with a D-dimer <2 µg/mL (99% CI; p < 0.01). When mean D-dimer and corresponding oxygen requirements were calculated per hospitalization days category, the D-dimer levels and oxygen requirements were noted to follow the same trends indicating that both values tended to increase and decrease simultaneously. The study concludes daily D-dimer trends can predict COVID-19 patient survival or daily oxygen requirements indicating that D-dimer can be the miracle molecule for COVID-19 prognosis.

Abstract
Photocathodes are key elements in high-brightness electron sources and ubiquitous in the operation of large-scale accelerators, although their operation is often limited by their quantum efficiency and lifetime. Here, we propose to overcome these limitations by utilizing direct-laser nanostructuring techniques on copper substrates, improving their efficiency and robustness for next-generation electron photoinjectors. When the surface of a metal is nanoengineered with patterns and particles much smaller than the optical wavelength, it can lead to the excitation of localized surface plasmons that produce hot electrons, ultimately contributing to the overall charge produced. In order to quantify the performance of laser-produced plasmonic photocathodes, we measured their quantum efficiency in a typical electron gun setup. Our experimental results suggest that plasmon-induced hot electrons lead to a significant increase in quantum efficiency, showing an overall charge enhancement factor of at least 4.5 and up to 25. A further increase in their efficiency was observed when combined with semiconductor thin-films deposited over the laser processed surfaces, pointing at potential pathways for further optimization. We demonstrate that simple laser-produced plasmonic photocathodes outperform standard metallic photocathodes, and can be directly produced in-situ at the electron gun level in vacuum environments and without any disruptive intervention. This approach could lead to unprecedented efficient and continuous operation of electron sources, and is useful in many applications across scientific disciplines requiring high average and peak current electron beams.
Rereading Salamon: Why Voluntary Failure Theory is Not (Really) About Voluntary Failures
Authors: Toepler Stefan 
Published: October 2023

Abstract
Voluntary Failure or Interdependence Theory remains among the most salient of Salamon’s conceptual contributions to nonprofit studies globally. Broad criticism has been scarce. Yet, there are questions about how the theory can be tested, or whether it is even testable in the first place. A lot of these questions focus on the four voluntary failures. In this commentary, I argue that the role of the voluntary failures is often overemphasized as part of Salamon’s theoretical constructs. This overemphasis in turn lends itself to problematic interpretations of his theory, which was not intended to offer a ‘failure rationale’ for the existence of the nonprofit sector—akin to the twin failures of the market and government, but at its core seeks to provide a rationale for the positive collaborative relations between government and the nonprofit sector. Within that rationale, the voluntary failures play only a relatively minor role.
Effects of programmed maintenance shutdowns on effluent quality of a bleached kraft pulp mill
Authors: Del’Antonio Nelson Rubens Nascimento , Fioreze Mariele , Caliari Márcio , Amaral João Pedro , Silva Claudio Mudadu 
Published: October 2023

Abstract
Routinely, the mills perform programmed maintenance shutdowns (PMS) that can affect the characteristics of the effluents and the performance of the effluent treatment plant (ETP). A careful planning of the PMS, along with the use of industrial process sectorial spill control and the use of the emergency spill lagoon have considerably minimized these effects. The Suzano pulp mill located in Aracruz (Brazil) has three production lines and carry out, on average, PMS of each production line separately, every 15 months of operation. The purpose of the study was to evaluate the effects of the PMS on the effluent characteristics and performance of the ETP compared to the periods of normal operation. The results showed that during the PMS, the physicochemical characteristics of the raw and treated effluents were like those found during normal operation. The lower organic loads found in the effluents during the PMS periods were associated with the decrease of the flow rates and the increase of the hydraulic retention time of the ETP, causing a better performance of COD, BOD, TSS and AOX removal. A proper planning of the PMS improved the performance of the ETP and the treated effluent quality remained similar to those during the normal operating period.
Conductive and self-cleaning composite membranes from corn husk nanofiber embedded with inorganic fillers (TiO2, CaO, and eggshell) by sol–gel and casting processes for smart membrane applications
Authors: Posri Surapit , Tangboriboon Nuchnapa 
Published: October 2023

Abstract
The utilization of corn husk as a renewable bio-cellulose material for producing bio-composite membranes through wet chemical and sol–gel process offers numerous advantages. It is an abundant, inexpensive, nontoxic, and readily available agricultural waste product. To enhance the properties of bio-composite membranes, various particulate ionic fillers such as titanium dioxide, calcium oxide, and eggshell (as a source of calcium carbonate) are incorporated in different weight percentages (0, 1, and 5%). These fillers act as additives to the corn husk nanofiber mixed with polyvinyl alcohol during the formation of the biomembrane. The resulting biocomposite membranes exhibit several desirable characteristics. They are lightweight, easy to shape, biodegradable, nontoxic, and possess excellent physical, mechanical, thermal, and electrical properties. Moreover, the addition of 5 wt% of eggshell powder leads to an increase in the dielectric constant and electrical conductivity, reaching approximately 3.300 ± 0.508 and 1.986 × 103 (Ω·m)−1, respectively. These measurements were taken at a frequency of 500 Hz and a temperature of 27°C. Furthermore, these membranes demonstrate self-cleaning abilities due to a contact angle greater than 90°. The electrical properties of the biocomposite membrane improve with a higher percentage of inorganic filler, making them suitable for applications in smart membranes, as well as mechanical, electrical, and thermal systems.
The Slovenian Perception of the EU: From Outstanding Pupil to Solid Member
Authors: Bučar Maja , Udovič Boštjan 
Published: October 2023

Abstract
From its early stages, the discussion on Slovenian independence included the clear ambition to join the European Community/Union. This objective was achieved in 2004. The support of membership was very high among Slovenians and has remained so ever since. Various domestic and external factors have affected the level of public support, but the country has never questioned its belonging to the EU. In fact, as the authors show, trust in EU policymaking has often been above EU average. There were instances when Slovenia expected a higher level of support from European institutions, but among all social groups, from politicians to businesspeople to NGOs to the wider public, there was no real alternative. This, however, does not suggest that understanding of the intricate functioning of the EU is at a sufficiently high level that the small country could effectively shape EU policies.
Romania: A Case of Differentiated Integration into the European Union
Authors: Oehler-Șincai Iulia Monica 
Published: October 2023

Abstract
This article identifies what is specific about Romania’s differentiated integration (DI) into European institutions. It outlines Romania’s expectations and priorities towards the European Union (EU) across three time periods: 1990–2000, 2001–2006 and 2007 onwards. Through this, it evaluates multiple perspectives on EU membership: DI; the development of macro-economic indicators; and Romanian attitudes towards European integration. In some areas, Romania has recorded substantial progress; in others it is still behind other Central and East European member states. Romania remains one of the most determined supporters of EU integration, as membership is considered a key impulse for economic stability and growth. Even if Romania is still outside the Schengen area and the eurozone, it continues to adhere to its accession objectives.

Published: October 2023

Abstract
The authors offer an analysis of the economic and political development of the independent Slovak Republic on its way to the EU as well as of its positions in strategic policy fields since it became an EU member state in 2004, such as migration policy, enlargement policy, the rule of law, and security on the EU’s eastern border. Slovakia’s stance vis-à-vis the values of the EU are assessed by an analysis of government programme declarations over the last 20 years. The authors show how economic success and GDP growth has influenced Slovakia’s support for EU membership, as well as how the country has positioned itself with regard to policy development and national interests on the one hand and to achieving EU goals and policies on the other.
