Published: March 2024

Η παρούσα διατριβή εκκινά με μία παράθεση των Αρχών Πολιτικής Επικοινωνίας. Παρατίθενται βασικά ορόσημα της εξέλιξης του επιστημονικού κλάδου της Πολιτικής Επικοινωνίας, των επιρροών του από διαφορετικές επιστήμες, όπως της Ψυχολογίας, και τεχνολογίες, όπως η τηλεόραση και το διαδίκτυο, καθώς και ορισμένα χαρακτηριστικά παραδείγματα πρακτικής εφαρμογής Πολιτικής Επικοινωνίας τον 20ο αιώνα. Στη συνέχεια επιχειρείται μία πιο θεωρητική και φιλοσοφική προσέγγιση των αρχών της Πολιτικής Επικοινωνίας, ως συγκερασμός των όρων της Πολιτικής και της Επικοινωνίας. Στα κύρια κεφάλαια της διατριβής ασχολούμαστε αφενός με τέσσερα έργα του Ξενοφώντα, τον Ιέρωνα, τον Οικονομικό, την Κύρου Παιδεία και τον Αγησίλαο, αφετέρου με το Εγχειρίδιο του Καλού Αυλικού του Μπαλτασσάρε Καστιλιόνε. Εξετάζουμε την Πολιτική Σκηνοθεσία του κάθε έργου, δηλαδή τον τρόπο κατά τον οποίο είναι δομημένο το πολιτικό περιβάλλον του κάθε έργου, το οποίο με τη σειρά του γεννά συγκεκριμένες πολιτικής συνθήκες και κατά συνέπεια επικοινωνιακές αναγκαιότητες. Απομονώνουμε τα διαφορετικά μέρη που ασκούν Πολιτική Επικοινωνία, τις επιδιώξεις τους και εν συνεχεία πρώτον τη στρατηγική επικοινωνίας τους και δεύτερον τους τρόπους υλοποίησης αυτής της στρατηγικής. Στο τελευταίο κεφάλαιο ομαδοποιούμε τα ευρήματά μας ως προς τις συνθήκες πολιτικής σκηνοθεσίας και το είδος του κοινωνικού συμβολαίου που τις διαμορφώνει, το πρότυπο του ηγέτη και των λοιπών πολιτικών δρώντων του κάθε περιβάλλοντος, τις στοχεύσεις και τα μέσα Πολιτικής Επικοινωνίας καθώς και σταθερά ανθρωπολογικά χαρακτηριστικά των οποίων οι διαφορετικοί συνδυασμοί διαμορφώνουν διαφορετικές συνθήκες Πολιτικής Πράξης και Επικοινωνίας.
Investigation of reporting bias in interrupted time series (ITS) studies: a study protocol

Published: March 2024

Background Systematic reviews that aim to synthesize evidence on the effects of interventions targeted at populations often include interrupted time-series (ITS) studies. However, the suppression of ITS studies or results within these studies (known as reporting bias) has the potential to bias conclusions drawn in such systematic reviews, with potential consequences for healthcare decision-making. Therefore, we aim to determine whether there is evidence of reporting bias among ITS studies. Methods We will conduct a search for published protocols of ITS studies and reports of their results in PubMed, MEDLINE, and Embase up to December 31, 2022. We contact the authors of the ITS studies to seek information about their study, including submission status, data for unpublished results, and reasons for non-publication or non-reporting of certain outcomes. We will examine if there is evidence of publication bias by examining whether time-to-publication is influenced by the statistical significance of the study’s results for the primary research question using Cox proportional hazards regression. We will examine whether there is evidence of discrepancies in outcomes by comparing those specified in the protocols with those in the reports of results, and we will examine whether the statistical significance of an outcome’s result is associated with how completely that result is reported using multivariable logistic regression. Finally, we will examine discrepancies between protocols and reports of results in the methods by examining the data collection processes, model characteristics, and statistical analysis methods. Discrepancies will be summarized using descriptive statistics. Discussion These findings will inform systematic reviewers and policymakers about the extent of reporting biases and may inform the development of mechanisms to reduce such biases.
Family Fat Talk Questionnaire – Polish adaptation
Authors: Ziółkowska Beata , Łoboda Dorota , Dąbrowska Aleksandra , Szrajda Justyna
Published: March 2024

Cel pracy

Ciało odgrywa istotną rolę w procesie kształtowania poczucia własnej wartości, zwłaszcza u osób w stadium adolescencji. Celem badań własnych była adaptacja samoopisowego narzędzia Family Fat Talk Questionnaire (FFTQ) Mc Donald i zespołu.

Metoda

Badaniem objęto 391 osób na przełomie późnej adolescencji i wczesnej dorosłości. Zastosowano: 1) ankietę osobową – celem kontrolowania zmiennych ubocznych, 2) Family Fat Talk Questionnaire w polskiej wersji językowej (FFTQ-PL) oraz 3) Kwestionariusz wizerunku ciała (KWCO) A. Głębockiej, dla sprawdzenia trafności zewnętrznej. Badania prowadzono online od grudnia 2022 do lutego 2023.

Wyniki

Wyniki badań wskazują, że FFTQ-PL ma zadowalającą rzetelność, trafność zewnętrzną, a jego dwuczynnikowa konstrukcja (czynnik 1. – „Ja”; czynnik 2. – „Rodzina”) potwierdziła się. Odnotowano ponadto, że większe natężenie rodzinnego fat talk występuje u kobiet niż u mężczyzn; (najwyższy wynik w FFTQ-PL uzyskały osoby identyfikujące się jako „inna płeć”, jednak z uwagi na niską liczebność tej podgrupy, obserwację tę należy traktować z dużą ostrożnością). Udowodniono też, że wysoki wynik w zakresie rodzinnego fat talk mierzony FFTQ-PL współistnieje z wysoką wartością wskaźnika masy ciała (BMI), z większą różnicą w zakresie masy ciała realnej i idealnej, z większym poczuciem bycia grubym, mniejszym poczuciem atrakcyjności i większym przekonaniem, że myślenie o własnym ciele wynika ze stosunku rodziny i bliskich do cielesności.

Wnioski

Miarę tę warto wykorzystać w badaniach przesiewowych do identyfikowania osób – szczególnie adolescentów – angażujących się w autodewaluujące konwersacje na gruncie rodziny. Okazuje się bowiem, że fat talk, szczególnie w przypadku osób o negatywnym obrazie własnego ciała, może stać się czynnikiem ryzyka dla podejmowania ryzykownych praktyk związanych z jedzeniem.

Tacit knowledge of places. Experiences from the post-agrarian countryside
Authors: Tobiasz-Lis Paulina , Wójcik Marcin
Published: March 2024

This article is framed by a broader discussion on the new meanings conferred by rural areas, and the construction of rurality recently undertaken by human geographers. The aim of the research presented here has been to identify perceptions of the countryside in Poland, at a time when a fundamental transition from agrarian to post-agrarian communities has already taken place. After a briefreview of the literature and a presentation of the contemporary conditions of rural development in Poland, the paper presents the results of the study conducted in 22 pre-selected villages in Poland. The social research involved semi-structured interviews and freehand sketches exemplifying tacit knowledge about these places, i.e. the symbolic meaning attributed by people to their living spaces. Results of this research show that uncovering this knowledge generates a variety of information useful in interpreting contemporary rurality as shaped by dynamic change in Poland’s economy and social life.
Shaping a model of transformation in a huge centre of zinc and lead smelting: case study of Szopienice district in the city of Katowice (Poland)
Authors: Krzysztofik Robert , Boroń Piotr , Dragan Weronika , Grudniewski Jakub
Published: March 2024

The problem of dynamic transformations within complex settlement systems poses an important challenge to planning. This is particularly true of post-industrial and post-mining regions, whose economic past adds an additional dimension affecting development and spatial policy. However, the article highlights the case of a settlement (Szopienice – a district of the city of Katowice in southern Poland) with a heterogeneous genesis in relation to the (post-)mining region in which it is located. Taking into account its economic development founded on zinc and lead metallurgy, the difficulties of development projection are pointed out. These difficulties are emphasised by a focus on the importance of paying attention to this type of locality from several research perspectives. In addition to the aforementioned heterogeneity, the role of “in-between” town locations and spatial peripheralisation is highlighted.
Abbasid Jumeirah, Dubai. An Overview of the Site and Its Architectural Stucco Decoration
Authors: Juchniewicz Karol , Lic Agnieszka
Published: March 2024

Jumeirah (Dubai) is one of the most important sites for the understanding of the Abbasid period in eastern Arabia. At the same time, it is severely understudied and the small number of publications available on the subject situates Jumeirah on the margins of academic debate about the region in the Islamic period. This paper aims to prompt discussion on Jumeirah by presenting an overview of the site, a summary of archaeological research and a preliminary study of the typology of stucco decorations. Some issues regarding problems with the reconstructions and renovations of the buildings are also raised. The study of stuccoes contributes to a better understanding of the site’s chronology, indicating its main phase of occupation to the Abbasid period and the possible existence of an earlier, pre-ninth or early ninth century phase.
Investigating the Neolithic Presence in South-Central Oman: The DUQ-25A Rock Shelter
Authors: Maiorano Maria Pia , Chlachula Dominik , Danielisová Alžběta , Garba Roman
Published: March 2024

Over the past decade, extensive surveys have been carried out in the wider area surrounding the city of Duqm (south-central Oman). During fieldwork in 2023, research on the Neolithic encampment in the Wādī Ṣayy area was conducted. Numerous locations surrounding this large wadi have yielded evidence of Neolithic occupation. The proximity to chert outcrops and the presence of elevated fluvial terrace systems overlooking the wadi floodplains likely played a pivotal role in attracting human habitation during that period. Among these sites, DUQ-25A stands out for its exceptional preservation and the abundance of flint scatters. The excavation at the site aimed to achieve multiple objectives: validating the site’s chronology, expanding our understanding of its spatial extent and occupational sequence and filling the gaps in our knowledge about Neolithic societies in south-central Oman. Our research aims to provide new perspectives for the study of the Early and Middle Holocene in Al-Wusṭā.
The Gebelein Region in the Third Intermediate and Late Periods
Authors: Ejsmond Wojciech , Kaczanowicz Marta
Published: March 2024

While relatively much is known of Gebelein in the second and third millennia BCE, as well as the Ptolemaic times, the role of the town of Per-Hathor and its surrounding in the Third Intermediate (c. 1076–747 BCE) and Late (c. 747–332 BCE) periods remains largely obscure. The aim of this paper is to examine the existing sources pertaining to the history of Gebelein with the particular focus on state activities in the area, diachronic changes in settlement pattern and sacral topography, as well as funerary landscape in the first three-quarters of first millennium BCE and analyse the available information in a regional context. For this, published and unpublished records are utilised, together with the results of the current field prospection in Gebelein.
Potmarks on Early Dynastic and Old Kingdom Bread Moulds from the Settlement Layers of Tell el-Murra
Authors: Kazimierczak Magdalena
Published: March 2024

Early Dynastic and Old Kingdom bread moulds belong to the type of vessels on which potmarks appear the most often, which is a phenomenon recorded during works conducted at different sites. Excavations carried out at the Tell el-Murra between 2011 and 2019 produced a significant number of vessels of this type with various marks. This paper is devoted to the 118 pre-firing marks from Early Dynastic and Old Kingdom bread moulds from the settlement layers at the Tell el-Murra. The paper comparatively analyses marks from two subsequent chronological periods, with the aim to test the validity of theories regarding their function and meaning, based on examples from Tell el-Murra. The study concludes that the high frequency of potmarks on bread forms was not accidental, but related to certain economic processes and changes, as also indicated in this paper.
‘The Lord defends refugees, protects the orphans and widows’ (Psalm 146:9). Emerging Challenges in Supporting People after Loss and Traumatic Events
Authors: Krakowiak Piotr , Mejzner Mirosław
Published: March 2024

This study, rooted in patristics and social sciences, delves into the historical evolution of support for orphans and widows in the Christian and Catholic tradition, underscoring its profound significance in the identity of these faith-based communities. Tracing the modes of assistance from pre-Christian times through the Old and New Testaments and the teachings of the Church Fathers, the paper elucidates various aspects of the caregiving process. Additionally, it explores the evolving sensitivities across different epochs in modernity, encompassing the contemporary, postmodern and recent years, with a specific focus on the periods before, during and after the COVID-19 pandemic. In light of this analysis, a fundamental question arises: What are the primary pastoral responsibilities of Catholic parishes in Poland regarding support to individuals who have experienced the loss of loved ones, borne multiple losses or endured severe traumas (such as war refugees from Ukraine in local communities)? This work provides guidance to over 10,000 Catholic parishes in Poland, considering the context of an aging society and the lessons derived from the COVID-19 pandemic. It extends an invitation for further research and the initiation of practical endeavours by pastoral theologians and specialists in social and healthcare, to ensure the highest quality of care in parish communities and local societies.
Inefficient Forecasts at the Sportsbook: An Analysis of Real-Time Betting Line Movement
Authors: Simon Jay
Published: March 2024

This paper tests the efficiency of a set of sports betting markets using detailed betting line movement from opening until closing for four different sportsbooks for each of 3,681 Major League Baseball games. The reliability of the markets’ forecasts are assessed at several lead times. The forecasts are mostly reliable, but there are simple betting strategies that would have yielded significant profit. In addition, forecasts do not always improve monotonically as the games get closer, despite more information being available; forecasts at weekend day games’ start times are significantly worse than forecasts 90 minutes earlier. Furthermore, analysis of the sequences of forecasts within individual games reveals that these betting markets do not incorporate information optimally. There is sufficient evidence to reject weak form market efficiency; specifically, betting lines tend to overreact, exhibiting significant negatively autocorrelated changes that could be exploited by sophisticated bettors.

This paper was accepted by Manel Baucells, behavioral economics and decision analysis.

Halal Information in Customer Value Disclosure
Authors: Pane Zulfikar Ikhsan , Yohana Yohana
Published: March 2024

Indonesia has a majority Muslim population, so consumers have the right to know the halalness of the products/services they consume. In addition, halal information can be of value to customers because it is a differentiator from similar products/services offered by other producers. This study aims to propose halal information as a novelty in Customer Value Disclosure (CVD). This novelty is important to reduce information asymmetry, provide value added and competitive advantage for companies, especially when operating in areas with a majority Muslim population. In addition, this novelty can be studied in further studies associated with other variables such as stock price, firm value, future profitability, cost of equity, personnel readiness and others. Through a literature review with reference to two studies that specifically discuss Customer Value Disclosure (CVD) and the annual reports of several companies, it is concluded that halal information can be added to the disclosure because the company has provided this information in the annual report. The information is in the form of the company's commitment and achievements towards halal products/services and halal certification obtained.

Published: March 2024

A thickener such as gelatin is essential in increasing viscosity and forming a gel system. Nowadays, gelatin is one of the most popular thickeners in food, pharmacy, and cosmetic products. Animal skins which lead to halal issues are still common sources of gelatin. Crude konjac flour (CKF) which is sourced from porang tubers and has a high degree of purity of glucomannan (GM) is a potential substitute for animal skins. Moreover, the use of KGM also supports national programs of processing agricultural products into finished products ready to export. This study applies five different CKF variants as panna cotta (PC) thickener: CKF from the fresh bulb of porang (Amorphophallus oncophyllus sp.) (CH-UP), CKF from chips of Porang (CH-CP), a native CKF, as well as laboratory-purified products of CKF (>90%-w of GM content) (DM-CKF-M3X-50, and DM-CKF-M3X-96), and commercially products of porang flour (K-TPO and K-TPM) were applied to make PC; substituting gelatin. Only CKF, DM-CKF-MX-50, and DM-CKF-M3X-96 successfully thickened PC in terms of appearances. Further, organoleptic analysis was applied to CKF, DM-CKF-MX-50, and DM-CKF-M3X-96. According to the organoleptic analysis, PC with CKF, DM-CKF-MX-50, and DM-CKF-M3X-96 was more preferred by the respondents than commercial PC. In overall, CKF application on PC exhibited improved sensory properties and tastes of PC.
A multidisciplinary diagnostic centre for early detection of cancer in patients with non-specific symptoms: a service evaluation
Authors: Jordon Louise H , Kumar Ritesh , Coles Rebecca , Deacon Julie , Win Thida
Published: March 2024

Background/Aims

Symptoms of malignancy are often vague and non-specific, leading to delayed diagnosis and treatment. The multidisciplinary diagnostic centre was established in 2017 to facilitate the shortest and safest route to detecting cancer in such cases. This study aimed to evaluate the service model and work towards a business case for more widespread adoption of the multidisciplinary diagnostic centre service.

Methods

Data from all patients managed by the service from 2017–21 were collected contemporaneously. After 51 months, service data were examined against the aims of the service, focusing on patient demographic characteristics, main reasons for referral, main diagnostic tests performed, patient outcomes and time from referral to discharge.

Results

Between 2 February 2017 and 30 April 2021, 899 patients were referred to the centre. Weight loss was the most common reason for referral. During this period, 96 (10.7%) patients were diagnosed with a cancer. Of these diagnoses, 42.9% were made within 28 days of referral, improving to 60.6% in the final year of the service evaluation.

Conclusions

The multidisciplinary diagnostic centre demonstrates the importance and potential of having a dedicated referral pathway for patients presenting with vague, concerning symptoms.

Investigation of the effect of goal-oriented dance movement therapy on depressive symptoms in people with schizophrenia: a rater-blinded randomised controlled study
Authors: Gökcen Arif , Ekici Gamze , Bağcı Etkin , Şen Duygu Tiryaki
Published: March 2024

Background/Aims

Depression is a common symptom in schizophrenia and can negatively affect treatment. The aim of this study was to examine the effects of goal‑oriented dance or movement therapy on depressive symptoms in individuals diagnosed with schizophrenia.

Methods

The study was designed as a randomised controlled rater‑blinded study, in which 32 individuals diagnosed with schizophrenia were randomly assigned to either the intervention (dance movement therapy) group or control group. The intervention consisted of twice‑weekly goal‑oriented dance movement therapy sessions, with each session lasting approximately 40–50 minutes, for a total of 8 weeks. Depressive symptoms were evaluated using the Calgary Depression Scale for Schizophrenia.

Results

The depressive symptoms before and after the intervention were compared. No significant differences between groups were observed at baseline. There was no change in the control group, whereas a significant improvement on depressive symptoms was observed in the total Calgary Depression Scale for Schizophrenia score in the dance movement therapy group after the intervention.

Conclusions

Goal‑oriented dance movement therapy is an effective treatment for the depressive symptoms in schizophrenia patients in addition to conventional treatments. Although the results are favourable, further studies are needed to test its effectiveness.

Implications for practice

In the traditional treatment of schizophrenia, it is important to evaluate depression and support the treatment with approaches such as dance movement therapy.

Authors: Aafreen Aafreen , Khan Ashfaque , Khan Abdur Raheem , Ahmad Ausaf , Parween Saba , Maurya Neeraj Kumar , Alshehri Mohammed M , Shaphe Mohammad Abu , Ahmed Hashim , Mirza Hadia
Published: March 2024

Background/Aims

The quadriceps angle, which depicts the quadriceps muscle's mechanical effect on the knee, is frequently used as an assessment metric when diagnosing a variety of knee-related issues. Smartphone goniometer applications have clinical assessment capabilities that can be used instead of the universal goniometer. The aim of this study was to analyse the criterion validity and inter- and intra-rater reliability of a smartphone goniometer application for measuring the quadriceps angle.

Methods

A total of 50 typically healthy women were included in this study. The quadriceps angle was evaluated with the universal goniometer as the gold standard and the Angulus smartphone goniometer application on each participant. The intraclass correlation coefficient and 95% confidence intervals were used to analyse reliability, while the standard error of the mean was used to calculate precision. Bland-Altman plots and 95% limits of agreement were used to establish the levels of agreement between the smartphone goniometer application and the universal goniometer. The Pearson correlation coefficient was used to quantify the smartphone goniometer application criterion validity in comparison to the universal goniometer.

Results

The smartphone goniometer application had good intra-rater reliability (intraclass correlation coefficient 0.99; 95% confidence interval 0.96–1) and inter-rater reliability (intraclass correlation coefficient 0.98; 95% confidence interval 0.94–1). A strong and significant correlation was found between the universal goniometer and the smartphone goniometer application, showing good criterion validity (r=0.99; 95% confidence interval 0.98–0.99; P=0.006).

Conclusions

The use of the smartphone goniometer application to measure the quadriceps angle was valid and demonstrated excellent intra- and inter-rater reliability levels.

Implications for practice

The smartphone goniometer application can be used in clinical practice as a valid and reliable quadriceps angle measurement tool.

Authors: Akyurek Gokcen , Aydoner Selen , Ceyhan Irem
Published: March 2024

Background/Aims

Instrumental activities of daily living are meaningful and purposeful activities that contribute meaning to people's lives and reflect their values and cultures in the community. This study investigated the effects of an occupation-based intervention for instrumental activities of daily living on stress levels, quality of life, and participation in instrumental activities of daily living in people with disabilities.

Methods

A total of 18 people with different types of disabilities (intervention group n=9, control group n=9) were recruited. The occupation-based intervention took place in 45-minute sessions, with a total of 16 sessions held twice a week for 8 weeks. The measurement tools used were the Lawton–Brody Instrumental Activities of Daily Living Scale and the Waisman Activities of Daily Living Scale to evaluate activities of daily living, the Mini-Mental State Examination to examine cognitive status, the 36-item Short Form Survey questionnaire to assess quality of life, the Perceived Stress Scale to examine stress level, and the Community Integration Questionnaire to evaluate participation in the community were used.

Results

After 8 weeks, there were significant improvements in performance and participation in instrumental activities of daily living, stress and quality of life in the intervention group intervention group had significant increases in instrumental activities of daily living (z=−2.6, P=0.008), vitality (z=−0.5, P=0.041), role emotional (z=−2.7, P=0.008), role physical (z=−2.3, P=0.020), general health (z=−3.3, P=0.001) and participation (z=−1.3, P=0.023). There were also significant reductions in stress (z=−2.8, P=0.005) and bodily pain (z=−3.2, P=0.001) scores compared to the control group

Conclusions

The occupation-based intervention reduced the stress levels of people with a range of disabilities and increased their ability to perform activities of daily living], participation in activities of daily living and improved their quality of life.

Implications for practice

Occupational therapists could use occupation-based interventions to reduce the stress levels of people with disabilities and increase their performance and participation in activities of daily living and improve their quality of life.
Cardiac function may be compromised in patients with elevated blood cobalt levels secondary to metal-on-metal hip implants
Authors: Jenkinson Mark R. J. , Meek Dominic R. M. , Tate Rothwelle , Brady Adrian , MacMillan Sandy , Grant Helen , Currie Susan
Published: March 2024

Aims

Elevated blood cobalt levels secondary to metal-on-metal (MoM) hip arthroplasties are a suggested risk factor for developing cardiovascular complications including cardiomyopathy. Clinical studies assessing patients with MoM hips using left ventricular ejection fraction (LVEF) have found conflicting evidence of cobalt-induced cardiomyopathy. Global longitudinal strain (GLS) is an echocardiography measurement known to be more sensitive than LVEF when diagnosing early cardiomyopathies. The extent of cardiovascular injury, as measured by GLS, in patients with elevated blood cobalt levels has not previously been examined.

Methods

A total of 16 patients with documented blood cobalt ion levels above 13 µg/l (13 ppb, 221 nmol/l) were identified from a regional arthroplasty database. They were matched with eight patients awaiting hip arthroplasty. All patients underwent echocardiography, including GLS, investigating potential signs of cardiomyopathy.

Results

Patients with MoM hip arthroplasties had a mean blood cobalt level of 29 µg/l (495 nmol/l) compared to 0.01 µg/l (0.2 nmol/l) in the control group. GLS readings were available for seven of the MoM cohort, and were significantly lower when compared with controls (-15.5% vs -18% (MoM vs control); p = 0.025)). Pearson correlation demonstrated that GLS significantly correlated with blood cobalt level (r = 0.8521; p < 0.001). However, there were no differences or correlations for other echocardiography measurements, including LVEF (64.3% vs 63.7% (MoM vs control); p = 0.845).

Conclusion

This study supports the hypothesis that patients with elevated blood cobalt levels above 13 µg/l in the presence of a MoM hip implant may have impaired cardiac function compared to a control group of patients awaiting hip arthroplasty. It is the first study to use the more sensitive parameter of GLS to assess for any cardiac contractile dysfunction in patients with a MoM hip implant and a normal LVEF. Larger studies should be performed to determine the potential of GLS as a predictor of cardiac complications in patients with MoM arthroplasties.

Survival of cemented short Exeter femoral components in primary total hip arthroplasty
Authors: van Veghel Mirthe H. W. , van der Koelen Remy E. , Hannink Gerjon , Schreurs B. W. , Rijnen Wim H. C.
Published: March 2024

Aims

The aim of this study was to report the long-term follow-up of cemented short Exeter femoral components when used in primary total hip arthroplasty (THA).

Methods

We included all primary 394 THAs with a cemented short Exeter femoral component (≤ 125 mm) used in our tertiary referral centre between October 1993 and December 2021. A total of 83 patients (21%) were male. The median age of the patients at the time of surgery was 42 years (interquartile range (IQR) 30 to 55). The main indication for THA was a childhood hip disease (202; 51%). The median follow-up was 6.7 years (IQR 3.1 to 11.0). Kaplan-Meier survival analyses were performed to determine the rates of survival with femoral revision for any indication, for septic loosening, for fracture of the femoral component and for aseptic loosening as endpoints. The indications for revision were evaluated. Fractures of the femoral component were described in detail.

Results

The 20-year rate of survival was 85.4% (95% confidence interval (CI) 73.9 to 92.0) with revision for any indication, 96.2% (95% CI 90.5 to 98.5) with revision for septic loosening and 92.7% (95% CI 78.5 to 97.6) with revision for fracture of the femoral component. No femoral components were revised for aseptic loosening. There were 21 revisions of the femoral component; most (seven) as part of a two-stage management of infection. Fracture of the femoral component occurred in four THAs (1.0%) at 6.6, 11.6, 16.5, and 18.2 years of follow-up, respectively. Three of these were transverse fractures and occurred at the level of the lesser trochanter. In one THA, there was a fracture of the neck of the component.

Conclusion

THAs using cemented short Exeter femoral components showed acceptable rates of survival of the femoral component at long-term follow-up, in this young cohort of patients. Although fracture is a rare complication of these components, surgeons should be aware of their incidence and possible risk factors.

Long-term follow-up of an uncemented proximally hydroxyapatite-coated femoral stem in total hip arthroplasty
Authors: Yee Andy H. F. , Chan Vincent W. K. , Fu Henry , Chan Ping-Keung , Chiu Kwong Y.
Published: March 2024

Aims

The aim of this study was to evaluate the survival of a collarless, straight, hydroxyapatite-coated femoral stem in total hip arthroplasty (THA) at a minimum follow-up of 20 years.

Methods

We reviewed the results of 165 THAs using the Omnifit HA system in 138 patients, performed between August 1993 and December 1999. The mean age of the patients at the time of surgery was 46 years (20 to 77). Avascular necrosis was the most common indication for THA, followed by ankylosing spondylitis and primary osteoarthritis. The mean follow-up was 22 years (20 to 31). At 20 and 25 years, 113 THAs in 91 patients and 63 THAs in 55 patients were available for review, respectively, while others died or were lost to follow-up. Kaplan-Meier analysis was performed to evaluate the survival of the stem. Radiographs were reviewed regularly, and the stability of the stem was evaluated using the Engh classification.

Results

A total of seven stems (4.2%) were revised during the study period: one for aseptic loosening, three for periprosthetic fracture, two for infection, and one for recurrent dislocation. At 20 years, survival with revision of the stem for any indication and for aseptic loosening as the endpoint was 96.0% (95% confidence interval (CI) 92.6 to 99.5) and 98.4% (95% CI 96.2 to 100), respectively. At 25 years, the corresponding rates of survival were 94.5% (95% CI 89.9 to 99.3) and 98.1% (95% CI 95.7 to 99.6), respectively. There was radiological evidence of stable bony fixation in 86 stems (76.1%) and evidence of loosening in four (3.5%) at 20 years. All patients with radiological evidence of loosening were asymptomatic.

Conclusion

The Omnifit HA femoral stem offered promising long-term survival into the third decade.

Future research priorities for soft-tissue knee injuries
Authors: Osmani Humza T. , Nicolaou Nicolas , Anand Sanjeev , Gower Jonathan , Metcalfe Andrew , McDonnell Stephen
Published: March 2024

Aims

To identify unanswered questions about the prevention, diagnosis, treatment, and rehabilitation and delivery of care of first-time soft-tissue knee injuries (ligament injuries, patella dislocations, meniscal injuries, and articular cartilage) in children (aged 12 years and older) and adults.

Methods

The James Lind Alliance (JLA) methodology for Priority Setting Partnerships was followed. An initial survey invited patients and healthcare professionals from the UK to submit any uncertainties regarding soft-tissue knee injury prevention, diagnosis, treatment, and rehabilitation and delivery of care. Over 1,000 questions were received. From these, 74 questions (identifying common concerns) were formulated and checked against the best available evidence. An interim survey was then conducted and 27 questions were taken forward to the final workshop, held in January 2023, where they were discussed, ranked, and scored in multiple rounds of prioritization. This was conducted by healthcare professionals, patients, and carers.

Results

The top ten included questions regarding prevention, diagnosis, treatment, and rehabilitation. The number one question was, ‘How urgently do soft-tissue knee injuries need to be treated for the best outcome?’. This reflects the concerns of patients, carers, and the wider multidisciplinary team.

Conclusion

This validated process has generated ten important priorities for future soft-tissue knee injury research. These have been submitted to the National Institute for Health and Care Research. All 27 questions in the final workshop have been published on the JLA website.

Published: March 2024

Population aging has positioned as a key demographic change. This paper analyzes the characteristics of older adults in situations of dependence, care strategies and the profile of caregivers for Chile, Colombia, Paraguay, El Salvador and Uruguay. The population in a situation of functional dependence is mostly female and over 75 years old. Between 54% and 70% receive some type of care, with unpaid family care being the main care strategy. Unpaid caregivers are mostly women, under 65, and economically inactive. We evidence a negative relationship between the status of elderly caregiver and employment, that is stronger for women. Although elderly informal care leads to a lower probability of employment among individuals of all ages and income quintiles, the employment gap between caregivers and non-caregivers narrows substantially among higher-income people. Improving care for older people would have positive effects on female employment and inequality.

Slow Violence and the California Central Valley Prison in Rachel Kushner’s The Mars Room
Authors: Jackson Trevor
Published: March 2024

Abstract: This essay interrogates the carceral geography of the California Central Valley by examining Rachel Kushner’s novel The Mars Room (2018), which unfolds the life and limiting circumstances of a woman serving two life sentences. With capitalism as the driving force and background of this novel, this article examines the problem of representation posed by the prison in American society. Does the novel allow for a sharper perception of the loss wrought by the carceral state? I argue that Kushner uses the novel form to represent the slow violence of incarceration, which is a biopolitical project of the United States.
Impact of different receiver geometries on a reconfigurable intelligent surface assisted multi-cell VLC system in the presence of light path blockage
Authors: Sabui Deblina , Chatterjee Sourish , Khan Gufran S.
Published: March 2024

We report the effect of integrating metasurface-aided reconfigurable intelligent surfaces (RISs) on the signal-to-interference-plus-noise ratio (SINR) and data rate of a multi-cell visible light communication (VLC) system. RIS has been deployed in the channel between transmitter and receiver to redirect the reflected light in the desired directions, even in the absence of line-of-sight (LoS) links. Results show that the introduction of RIS has improved average SINR but reduced average illumination level compared to a no-RIS system. As the quantity of RIS increases, a discernible improvement in the maximum SINR value is observed. Here, three different receiver geometries, namely, a photodiode (PD), freeform diversity receiver (FDR), and modified FDR (MFDR), have been adopted. The impact of individual receivers has been reported in the presence of light path blockage. MFDR geometry is found to be most suitable with more coverage probability compared to the other two receivers. With (40cm×24cm) RIS area, during blockage, MFDR maintains an average SINR of 21.95 dB, which is 97.29% and 14.24% greater than PD and FDR, respectively.
Microwave photonics frequency measurement with improved accuracy based on an artificial neural network
Authors: An Xin , Yang Zhangyi , Liu Zuoheng , Zhang Youdi , Dong Wei
Published: March 2024

Photonics-assisted techniques for microwave frequency measurement (MFM) show great
potential for overcoming electronic bottlenecks, with wild
applications in radar and communication. The MFM system based on the
stimulated Brillouin scattering (SBS) effect can measure the frequency
of multiple high-frequency and wide-band signals. However, the
accuracy of the MFM system in multi-tone frequency measurement is
constrained by the SBS bandwidth and the nonlinearity of the system.
To resolve this problem, a method based on an artificial neural
network (ANN) is suggested, which can establish a nonlinear mapping
between the measured two-tone signal spectra and the theoretical
frequencies. Through simulation verification, the ANN optimized
frequencies within the range of (0.5, 27) GHz of the MFM system show
79%, 76%, 70%, 44% reduction in errors separately under four spectral
signal-to-noise ratios (SNR) conditions, 20 dB, 15 dB,
10 dB, 0 dB, and the frequency resolution is improved
from 30 MHz to 10 MHz.
User-friendly oblique plane microscopy on a fully functional commercially available microscope base
Authors: Sirinakis George , Allgeyer Edward S. , Nashchekin Dmitry , St. Johnston Daniel
Published: March 2024

In this work we present an oblique plane microscope designed to work
seamlessly with a commercially available microscope base. To support
all the functionality offered by the microscope base, where the
position of the objective lens is not fixed, we adopted a two-mirror
scanning geometry that can compensate for changes to the position of
the objective lens during routine microscope operation. We showed that
within a ± 1 mm displacement range of the 100X,
1.35 NA objective lens away from its designed position, the PSF
size increased by <3% and <11% in the lateral and
axial dimensions, respectively, while the error in magnification was
<0.5% within volumes extending ± 10
µm about the focal plane. Compared to the more traditional
scan-lens/galvo-mirror combination, the two-mirror scanning geometry
offers higher light efficiency and a more compact footprint, which
could be beneficial to all OPM designs regardless of the use of a
commercial base or not.

Published: March 2024

Time-varying metamaterials are currently at the forefront of research, offering immense possibilities for intriguing wave manipulations. Temporal modulations of metamaterials have paved the way for unconventional realizations of magnetless nonreciprocity, wave amplification, frequency conversion, pulse shaping, and much more. Here, we overview the fundamentals and recent advancements of temporal interfaces in isotropic, anisotropic, and bianisotropic materials and metamaterials. Delving into the fundamentals of temporal scattering in media of different material classes, we draw insightful comparisons with phenomena observed at spatial interfaces. We specifically emphasize the potential of time-switched anisotropic and bianisotropic metamaterials in unlocking extraordinary temporal scattering phenomena. Furthermore, an overview of possible platforms to realize time-varying bianisotropic metamaterials is provided. Concluding with a glimpse into the future, we make a research outlook for time-varying anisotropic and bianisotropic metamaterials, highlighting their potential in obtaining exotic photonic time crystals and other dynamic electromagnetic structures.
