Abstract	Total knee arthroplasty (TKA) is a well-known surgical procedure performed to address end stage osteoarthritis. The main goal is to relieve pain, recover articular function and return to normal function as soon as possible. Over the years it is frequently performed in the elderly, but lately there is an increased demand in a younger and more active population. Up to 25% of patients feel dissatisfied about their TKA. The anterior cruciate ligament (ACL) is considered the main anteroposterior stabilizer of the knee; nevertheless the ACL is usually sacrificed during conventional TKA. Research shows this might be an unnecessary sacrifice in certain cases. The considerable dissatisfaction rate in mainly high-demanding patients, together with the literature reports on the importance of the ACL function, were the two main reasons for the development of bicruciate retaining (BCR) total knee arthroplasty. BCR TKA may offer superior knee kinematics and proprioception, through anterior cruciate ligament preservation, but requires a higher level of attention to obtain an accurate and precise component orientation to reach proper ligamentous balancing and restore the native knee biomechanics. Many surgeons abandoned its use due to its challenging technique and inconsistent results. Recent new BCR implant designs are promising. This systematic literature review aims to summarize the current state of BCR TKA and what to expect in the future.

Abstract	Scientific research is an essential pillar for the progress of countries, as a major driver of all their institutions. It is also considered the mainstay of development and improvement in all fields, achieving the welfare of peoples and preserving the entity of the state. That is why scientific research has become one of the methods of professional development. Scientific research is a structured intellectual process that a researcher performs fact-finding to solve problems in an organized scientific way called the research method. In light of crises and disasters, the urgent need for scientific research and planning for it is evident, and what is happening now from the COVID-19 pandemic crisis in our Arab and international world is the best evidence, and the acceleration of challenges in higher education institutions and scientific research centers, such as: globalization and the information and knowledge revolution, emphasized the need to develop scientific research which is the tool important for the basic strategic vision of economic, political and social progress. For this, it is necessary to adopt a strategic plan to invest in scientific research and apply its results in solving problems that affect society. The findings of the current study emphasized that the psychological researchers must conduct serious studies that touch the living reality and the real scientific need. As well as, the current study findings stressed on the importance of establishing a body to invest in scientific research in each country, which will examine the results of studies in the various branches of science that can be applied in reality, and contribute to solving the problems of people's lives, and follow-up on patents and innovations that can be applied.

Abstract	Background: Anxiety and concern are among the most common problems facing healthcare workers (HCWs) during epidemic diseases. Objective: To identify the predictive factors of anxiety, fears, and psychological distress among healthcare workers during the COVID-19 pandemic. Methods: An online survey method was used on a sample of 153 of HCWs; (110) frontline and (43) non-frontline HCWs. They answered on the Hamilton anxiety rating scale, the Kessler psychological distress scale (K10), and the COVID-19 Concerns Questionnaire. Results: The results demonstrated that 47.05% of HCWs have a severe level of fear related to COVID-19, 43.13% have very severe anxiety, and 30.71% experience severe psychological distress. The differences between frontline and non-frontline HCWs, female and male HCWs, and HCWs working in medical clinics, on quarantine, or in another place were significant in the three scales. Predictive factors of anxiety, fear, and psychological distress include working on the front lines, being female, and being over 50 years old. Meanwhile, working in a workplace with COVID-19 patients predicted anxiety and psychological distress, but not fears associated with COVID-19. Conclusion: HCWs have a high prevalence of symptoms of mental disorders that may interfere with their work. These results may have therapeutic applications during pandemics.

Abstract	How does the ideological segregation of online networks impact the spread of misinformation? Past studies have found that homophily generally increases diffusion, suggesting that partisan news, whether true or false, will spread farther in ideologically segregated networks. We argue that network segregation disproportionately aids messages that are otherwise too implausible to diffuse, thus favoring false over true news. To test this argument, we seeded true and false informational messages in experimental networks in which subjects were either ideologically integrated or segregated, yielding 512 controlled propagation histories in 16 independent information systems. Experimental results reveal that the fraction of false information circulating was systematically greater in ideologically segregated networks. Agent-based models show robustness of this finding across different network topologies and sizes. We conclude that partisan sorting undermines the veracity of information circulating on the Internet by increasing exposure to content that would otherwise not manage to diffuse.

Abstract	Because fact-checking takes time, verdicts are usually reached after a message has gone viral and interventions can have only limited effect. A new approach recently proposed in scholarship and piloted on online platforms is to harness the wisdom of the crowd by enabling recipients of an online message to attach veracity assessments to it. The intention is to allow poor initial crowd reception to temper belief in and further spread of misinformation. We study this approach by letting 4000 subjects in 80 experimental bipartisan communities sequentially rate the veracity of informational messages. We find that in well-mixed communities, the public display of earlier veracity ratings indeed enhances the correct classification of true and false messages by subsequent users. However, crowd intelligence backfires when false information is sequentially rated in ideologically segregated communities. This happens because early raters' ideological bias, which is aligned with a message, influences later raters' assessments away from the truth. These results suggest that network segregation poses an important problem for community misinformation detection systems that must be accounted for in the design of such systems.

Abstract	Objective: Recurrent depressive episodes are preceded by changing mean levels of repeatedly assessed emotions (e.g., feeling restless), which can be detected in real time using statistical process control (SPC). This study investigated whether monitoring changes in the standard deviation (SD) of emotions and negative thinking improves the early detection of recurrent depression. Method: Formerly depressed adults (N = 41) monitored their emotions five times a day for 4 consecutive months. During the study, 22 individuals experienced recurrent depression. We used SPC to detect warning signs (i.e., changing means and SDs) of four emotions (positive and negative affect with high or low arousal) and negative thinking. Results: SD Conclusions: Warning signs for depression manifest not only in changing mean levels of emotions and cognitions but also in increasing SDs. These warnings could eventually be used to detect not just who is at increased risk for depression but also when risk is rising. Further research is needed to evaluate the clinical utility of depression SPC. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Abstract	Purpose: The assistance of robot technology is introduced into the operating theatre to improve the precision of a total knee arthroplasty. However, as with all new technology, new technology requires a learning curve to reach adequate proficiency. The primary aim of this study was to identify the learning curve of an imageless robotic system with standardised laxity testing. The secondary aim of this study was to evaluate the accuracy of the intra-operative coronal alignment during the learning curve. Methods: A prospective study was performed on 30 patients undergoing robot-assisted total knee arthroplasty with an imageless robotic system (Corin, Massachusetts, USA) associated with a dedicated standardised laxity testing device. The learning curve of all surgical steps was assessed with intra-operative video monitoring. As comparison, the total surgical time of the last 30 patients receiving conventional total knee arthroplasty by the same surgeon and with the same implant was retrospectively assessed. Coronal lower limb alignment was evaluated pre- and post-operatively on standing full-leg radiographs. Results: CUSUM (cumulative summation) analysis has shown inflexion points in multiple steps associated with robot-assisted surgery between one and 16 cases, which indicates the progression from the learning phase to the proficiency phase. The inflexion point for total operative time occurred after nine cases. Robot-assisted total knee surgery required significantly longer operative times than the conventional counterpart, with an average increase of 22 min. Post-operative limb and implant alignment was not influenced by a learning curve. Conclusion: The introduction of an imageless robotic system with standardised laxity assessment for total knee arthroplasty results in a learning curve of nine cases based on operative time. Compared to conventional surgery, the surgeon is not able to reach time neutrality with the robotic platform. There is no learning curve associated with coronal limb or implant alignment. This study enables orthopaedic surgeons to understand the implementation of this surgical system and its specific workflow into clinical practice.

Abstract	Objective: To examine the effects of autoregulated (AUTO) and non-autoregulated (NAUTO) blood flow restriction (BFR) application on adverse effects, performance, cardiovascular and perceptual responses during resistance exercise. Methods: Fifty-six healthy participants underwent AUTO and NAUTO BFR resistance exercise in a randomised crossover design using a training session with fixed amount of repetitions and a training session until volitional failure. Cardiovascular parameters, rate of perceived effort (RPE), rate of perceived discomfort (RPD) and number of repetitions were investigated after training, while the presence of delayed onset muscle soreness (DOMS) was verified 24 hours post-session. Adverse events during or following training were also monitored. Results: AUTO outperformed NAUTO in the failure protocol (p<0.001), while AUTO scored significantly lower for DOMS 24 hours after exercise (p<0.001). Perceptions of effort and discomfort were significantly higher in NAUTO compared with AUTO in both fixed (RPE: p=0.014, RPD: p<0.001) and failure protocol (RPE: p=0.028, RPD: p<0.001). Sixteen adverse events (7.14%) were recorded, with a sevenfold incidence in the fixed protocol for NAUTO compared with AUTO (NAUTO: n=7 vs AUTO: n=1) and five (NAUTO) vs three (AUTO) adverse events in the failure protocol. No significant differences in cardiovascular parameters were found comparing both pressure applications. Conclusion: Autoregulation appears to enhance safety and performance in both fixed and failure BFR-training protocols. AUTO BFR training did not seem to affect cardiovascular stress differently, but was associated with lower DOMS, perceived effort and discomfort compared with NAUTO. Trial registration number: NCT04996680.

Abstract	This article explores the limits and opportunities for enhancing the democratic legitimacy of EU actions in the field of professional sport using new modes of governance. It presents a conceptual toolkit by which the ‘throughput legitimacy’ of an EU policy can be analysed. Analysing the throughput legitimacy of the European social dialogue, we establish that, by improving the latter, both input and output legitimacy can be increased. The EU could borrow some of the positive elements of the social dialogue approach and incorporate them in the steering of other issues in professional sport. For instance, it may be interesting to pre-establish certain conditions on representativeness and relevance for participation in the policy process. Crucially, working on a clear theme-per-theme-basis instead of organising outsized gatherings such as the EU sport forum would definitely benefit throughput legitimacy.
