Published: February 2024

This qualitative research study using a heuristic, descriptive phenomenological approach explored the lived experience of 12 DNPs who have returned to in pursuit of a PhD in nursing. Three themes were identified from the study participates: Wanting to Know Something More, Social-Individual Tensions, and Challenges to Transformational Learning. Based on the study findings, the DNPs desire to expand on their limited research knowledge and the tensions and challenges to transformational learning surrounding this quest were worth it as the participants gained personal and professional fulfillment.
Interpreting the orientation of objects: A cross-disciplinary review
Authors: Harris Irina M.
Published: February 2024

Is object orientation an inherent aspect of the shape of the object or is it represented separately and bound to the object shape in a similar way to other features, such as colour? This review brings together findings from neuropsychological studies of patients with agnosia for object orientation and experimental studies of object perception in healthy individuals that provide converging evidence of separate processing of object identity and orientation. Individuals with agnosia for object orientation, which typically results from damage to the right parietal lobe, can recognize objects presented in a range of orientations yet are unable to interpret or discriminate the objects’ orientation. Healthy individuals tested with briefly presented objects demonstrate a similar dissociation: object identity is extracted rapidly in an orientation-invariant way, whereas processing the object’s orientation is slower, requires attention and is influenced by the degree of departure from the canonical orientation. This asymmetry in processing can sometimes lead to incorrect bindings between the identity and orientation of objects presented in close temporal proximity. Overall, the available evidence indicates that object recognition is achieved in a largely orientation-invariant manner and that interpreting the object’s orientation requires an additional step of mapping this orientation-invariant representation to a spatial reference frame.

Published: February 2024

Mindfulness has been linked to a range of positive social-emotional and cognitive outcomes, but the underlying mechanisms are unclear. As one of the few traits or dispositions that are associated with both affective and cognitive benefits, we asked whether mindfulness is associated with affective and cognitive outcomes through a shared, unitary process or through two dissociable processes. We examined this in adolescents using behavioral measures and also reanalyzed previously reported neuroimaging findings relating mindfulness training to either affect (negative emotion, stress) or cognition (sustained attention). Using multivariate regression analyses, our findings suggest that the relationships between dispositional mindfulness and affective and cognitive processes are behaviorally dissociable and converge with neuroimaging data indicating that mindfulness modulates affect and cognition through separate neural pathways. These findings support the benefits of trait mindfulness on both affective and cognitive processes, and reveal that those benefits are at least partly dissociable in the mind and brain.
Enhanced feedback performance in off-resonance AFM modes through pulse train sampling

Published: February 2024

Dynamic atomic force microscopy (AFM) modes that operate at frequencies far away from the resonance frequency of the cantilever (off-resonance tapping (ORT) modes) can provide high-resolution imaging of a wide range of sample types, including biological samples, soft polymers, and hard materials. These modes offer precise and stable control of vertical force, as well as reduced lateral force. Simultaneously, they enable mechanical property mapping of the sample. However, ORT modes have an intrinsic drawback: a low scan speed due to the limited ORT rate, generally in the low-kilohertz range. Here, we analyze how the conventional ORT control method limits the topography tracking quality and hence the imaging speed. The closed-loop controller in conventional ORT restricts the sampling rate to the ORT rate and introduces a large closed-loop delay. We present an alternative ORT control method in which the closed-loop controller samples and tracks the vertical force changes during a defined time window of the tip–sample interaction. Through this, we use multiple samples in the proximity of the maximum force for the feedback loop, rather than only one sample at the maximum force instant. This method leads to improved topography tracking at a given ORT rate and therefore enables higher scan rates while refining the mechanical property mapping.

Published: February 2024

The development, grovth and productivity of livestock depend primarily on providing it with a variety of nutritious feeds. Daily feeds should consist of microbiologically synthesized protein, as well as a variety of seeds, mineral and vitamin supplements of animal and vegetable origin. Indeed, the maximum disclosure of the genetic potential of livestock largely depends on both the quantity and quality of feed. One of the stages of feed quality assessment is the measurement of their chemical composition. The chemical composition is not always constant and depends on many factors, including the species composition of plants, fertilizer application rates, climatic conditions and storage methods. The least accumulation of moisture in the soil was observed in areas where pasture grasses were regularly treated with wormwood. Pacture productivity was also the lowest in the control plots, where the average phyto-chemical composition over three years showed that the dynamics of protein content was the same in all pastures – the protein content reached a maximum at the beginning of the growing sea son and decreased from spring to autumn, while the lowest content of crude protein during harvesting in summer was in control plants of varieties.

The main problem: the article highlights the problem of dealing with stressful situations that are often found in the daily life of a human being. Purpose: to define the concepts of "stress" and "stress tolerance", to analyze some methods of working through stressful situations, stress relief. Methods: the article discusses active exercises and trainings to relieve tension and reduce stress, some self-regulation techniques. The results and their significance: the stress management techniques we offer can help a person cope with the abundance of stress that he has to face in everyday life. In addition, we also consider such techniques that can prevent the subsequent occurrence of so–called distress – the harmful effects of stress on the human body and its health. Each person has their own individual scenario of behavior under stress "in terms of frequency and form of manifestation." Most often, this scenario is learned in childhood. The direction of stress aggression is also repeated: at yourself or at others. One blames himself for everything and looks, first of all, for his mistakes. The other blames everyone around him, but not himself. The stress scenario learned in childhood is "triggered" almost automatically. In these cases, a minor violation of the usual rhythm of life and work is enough, as the stress mechanism turns on and begins to "unwind" almost against the will of the person. Self-regulation is a person's ability to arbitrarily manage their activities. The ability to self-regulate is a very important quality that helps a person maintain internal balance, preventing information from entering his consciousness that poses a threat to his well-being. It is also important to learn how to manage your feelings, independently regulate your emotional state.

Published: February 2024

The main problem: In the conditions of market uncertainty, the coronavirus pandemic, the absence of an officially articulated national idea, national interests and ideology in Kazakhstan, the problem of the lack of logically justified and coordinated coordinates of systemic thinking, an unambiguous paradigm of humanitarian thinking (analytical, pedagogical, managerial, economic, etc.) is becoming more and more clearly realized. as the most important conditions for personal, civil and professional self-determination. Purpose: to substantiate the general logical coordinates and methods of reformatting the ambiguous humanitarian paradigm used in the activity. Methods: the ontological principle of genetically meaningful logic, the method of transformation of concrete images of objects based on their abstract essence, the method of ascent from the abstract to the concrete, the speculative language of schematic images of thought and the language of methodological theory of activity. The results and their significance: logically justified universal abstract-concrete coordinates of universal motion are given. In relation to life and the world of activity, they can be concretized by coordinates: "standard of living – efficiency of activity", or "efficiency of activity – time", or "results – costs", or "quality – quantity", etc. The use of motion vectors in the logic of descent from the concrete to the abstract (NCA), ascent from the abstract to the concrete (AAC), as well as in their combination – logic CAC gives certainty to thinking. As an example, the scheme of the qualitative difference between educational (pre-professional) activities from professional ones using these methods and paired dialectical categories is given. The scheme and description of the functional model of the system object, considered as a rubicon of the transformation of educational activity into professional activity, are given. To reformat the indefinite, ambiguous paradigms of the humanities used in the activity into functional-logical, visible, constructive and unambiguous, it is recommended to use abstract-concrete coordinates, the methods given, the language of schematic images and the paradigm of the methodological theory of activity. As an example, the concept of a typical unit of activity development is given. A visible unambiguous paradigm is a necessary, but not sufficient prerequisite for adequate personal, civil and professional self-determination of a person in situations of high uncertainty. A sufficient prerequisite is the acquisition by subjects of appropriate reflexive-thinking abilities for self-determination, self-organization, self-regulation, etc.

Main problem: Implementing Education for Sustainable Development (ESD) in Higher Education Institutions (HEIs) is critical to facilitating the transition to sustainable development. However, little is known about the specific implementation processes that lead to the institutionalization of sustainability curricula in higher education institutions. This study cross-sections a number of international case studies using cluster analysis to clarify and highlight different implementation models: collaborative paradigm change; evolving institutional change from the bottom up; mandatory top-down institutional changes; externally driven initiatives; isolated initiatives and limited institutional changes. Purpose: Using cluster analysis, it is necessary to identify the different stages of ESD implementation, which can be implemented from the bottom up, top down, or both, identifying incentives that can come from a variety of external or internal stakeholders. Methods: In order to gain more general knowledge about the role of various drivers and barriers discussed in the literature, as well as specific implementation models, a comparative case study was conducted using a thematic review method. Cluster analysis was used to analyze the transformed data. The case study method is a meta-analytic method for systematically synthesizing and comparing different case studies using a specific coding scheme that converts qualitative data into quantitative data. Results and their significance: A cross-case analysis was conducted to better understand the sustainability curriculum delivery patterns that are common across different contexts. Most institutions and practitioners can benefit from these findings by defining a specific implementation framework for their institution, focusing on the most important and meaningful components of a particular university's ESD implementation model.

Published: February 2024

This study examines, via a partial experiment, the impact of the automotive technology program digital learning content on students' cognition. Consequently, the researcher conducted a partial experiment in this study to evaluate the functionality and usability of digital content. It fits with the social stigma of TVET, shaped by the perception that vocational education and training exist to serve school leavers rather than as an essential strategy to provide competent workers to the labour market. In total, 47 students in the Bachelor of Engineering Technology (Honours) in the Mechatronics (Automotive) programme participated in the investigation. The study's findings indicated that digital learning content has a significant positive influence on the cognitive and psychomotor achievement of students. The functionality of digital learning content is evaluated based on its capacity to produce the desired learning outcomes and its compatibility with the current curriculum. Assessing the usability of digital learning content involves measuring usability, navigation, and overall user experience. This evaluation demonstrates that the digital learning content is functional and usable, providing students with a positive learning experience. In addition, the results of this test demonstrate a significant improvement in students' cognitive achievement, indicating that digital learning content is beneficial in facilitating the learning process, and students are evaluated on their ability to perform practical tasks related to the course material. The results of this evaluation demonstrate a significant improvement in the psychomotor performance of students, indicating that digital learning content can enhance their practical skills. This study concluded that incorporating digital learning content into the curriculum for automotive technology has a significant positive influence on students' cognitive and psychomotor achievement. Available digital learning content can facilitate learning and provide students with a positive educational experience. These findings suggest that incorporating digital learning content into automotive technology programs may be a valuable addition to conventional learning methods. This study implies that digital learning effectively facilitates the learning process and that students are evaluated on their ability to complete practical tasks related to the course material. Consequently, this study was conducted to aid educators in using digital learning for students in automotive programs.

Published: February 2024

Online learning has become the choice to be implemented in various schools, due to the development of IT technology and the post-covid 19 pandemic making online learning increasingly popular to implement. Mobile Learning Management System is the most dominant used in online learning. This study aims to analyse the level of satisfaction of SMA and SMK teachers in West Sumatra in using the open source Mobile LMS in learning. Currently, teachers in supporting the learning process in their respective schools are still using the open source Mobile LMS with different platforms, some are using Google Classroom, Edmodo, and WhatsApp. Measuring satisfaction with the application of open source Mobile LMS was carried out using the use questionnaire method and structured interviews, to measure useability which consists of four categories, namely usefulness, ease of use, ease of learning and satisfaction. The analysis uses descriptive statistics, where the data is described in the form of tables and diagrams. From the results of data processing, it was found that on average teachers using open source LMS did not support learning at school because the LMS used did not accommodate learning and was not yet integrated, so that monitoring of the learning process of each teacher had not been carried out optimally. Shown by the results of each usefulness category 63%, ease of use 65%, ease of learning 60% and satisfaction 64%. They gave an unfavourable response because they were not as needed (usefulness), they were not easy to use (ease of use), they were not understood to be used (ease of learning) and they did not feel satisfied (satisfaction) while using the open source LMS.

Published: February 2024

Multiple studies have found a correlation between achievement goal orientation and academic buoyancy, which is the ability of students to overcome academic setbacks. Nevertheless, there is a lack of reference on achievement goal orientation for academic buoyancy among students in Federal Land Development Authority (FELDA) areas of Malaysia, especially for future workforce development. Hence, this study aims to examine the relationship between achievement goal orientation and academic buoyancy in mathematics achievement among FELDA students. This study employed a correlational research design to collect quantitative data via questionnaires from 462 students. The descriptive statistics indicated that the average academic buoyancy value was moderate. In addition, avoidance of mastery and performance had higher descriptive mean values than mastery approach and performance approach. Academic buoyancy was also found to be moderately positively associated with the mastery approach (r = 0.538), the performance approach (r = 0.411), and the performance avoidance orientation (r = 0.381). Mastery avoidance orientation exhibited the weakest positive relationship (r = 0.184). These findings shed light on how to foster students' achievement goal orientation in their ability to overcome academic setbacks. A sign of mastery avoidance had informed a need to focus on mastery of content for increasing academic buoyancy.

Published: February 2024

Injection of Distributed generators (DGS) and Shunt capacitors (SCS) simultaneously with system reconfiguration significantly promotes smart grid performance. In addition, system reconfiguration increases the injected distributed generation capacity in the system. This work proposes a wild horse optimizer (WHO) for the optimal siting and sizing of DGS and SCS in parallel with network reconfiguration. The proposed method aims to attain single and multi-objectives: minimizing active power loss, maximizing voltage stability index (VSI), and minimizing voltage deviation index (VDI). Five operational cases are introduced to elucidate the superior performance of the proposed method. The five cases are executed on IEEE 33-bus standard radial distribution test system. The single-objective function results are compared with other optimization algorithms. The simulation results belay that the proposed WHO optimizer has the best results for unfixed DGS and SCS locations.

Published: February 2024

Reverse migration has become a more pressing issue in recent times, owing to a range of factors like economic downturns, political instability, natural disasters, and the COVID-19 pandemic. The pandemic, in particular, has highlighted the vulnerability of migrant workers in urban areas, leading many to return to their rural homes. As a result, reverse migration necessitates focused attention and planning by governments, policymakers, and communities to ensure favourable outcomes for all parties involved. This paper aims to provide a fundamental research framework from research that utilized a machine learning approach to classify reverse migration based on evidence from Selangor, Malaysia. The research methodology involves selecting features for reverse migration classification models and identifying optimal hyperparameters and experimental settings through auto model preliminary analysis. Furthermore, based on the findings of the auto model, the methodology was enhanced with a manual setting of machine learning. Three machine learning algorithms, namely Decision Tree, Random Forest, and Gradient Boosted Trees were used. The results of the auto model and the manual process that used different split ratios were compared. All the machine learning algorithms performed with a high accuracy of over 90% and were efficient in completing prediction tasks in under a minute across various settings. The best machine learning model with an accuracy of 97.6% is Gradient Boosted Trees with a split ratio of 60:40. The paper presents findings that could prove useful for governments, legal planners, investors, and the community in strategizing and surviving through an artificial intelligence prediction approach.

Cosmic Tidal Reconstruction in Redshift Space
Authors: Zang 臧 Shi-Hui 诗慧 , Zhu 朱 Hong-Ming 弘明 , Schmittfull Marcel , Pen 彭 Ue-Li 威禮
Published: February 2024

Gravitational coupling between large- and small-scale density perturbations leads to anisotropic distortions to local small-scale matter fluctuations. Such local anisotropic distortions can be used to reconstruct large-scale matter distribution, known as tidal reconstruction. In this paper, we apply the tidal reconstruction methods to simulated galaxies in redshift space. We find that redshift-space distortions (RSDs) lead to anisotropic reconstruction results. While the reconstructed radial modes are more noisy mainly due to the small-scale velocity dispersion, the transverse modes are still reconstructed with high fidelity, and well correlated with the original large-scale density modes. The bias of the reconstructed field at large scales shows a simple angular dependence, which can be described by a form similar to that of the linear RSD. The noise power spectrum is nearly isotropic and scale independent on large scales. This makes the reconstructed tide fields an ideal tracer for cosmic variance cancellation and multi-tracer analysis and has profound implications for future 21 cm intensity mapping surveys.

Investigating the temperature and density structures of gas in massive protoclusters is crucial for understanding the chemical properties therein. In this study, we present observations of the continuum and thioformaldehyde (H2CS) lines at 345 GHz of 11 massive protoclusters using the Atacama Large Millimeter/submillimeter Array telescope. High spatial resolution and sensitivity observations have detected 145 continuum cores from the 11 sources. H2CS line transitions are observed in 72 out of 145 cores, including line-rich cores, warm cores, and cold cores. The H2 column densities of the 72 cores are estimated from the continuum emission, which are larger than the density threshold value for star formation, suggesting that H2CS can be widely distributed in star-forming cores with different physical environments. The rotation temperature and column density of H2CS are derived using the XCLASS software. The results show that the H2CS abundances increase as temperature rises and higher gas temperatures are usually associated with higher H2CS column densities. The abundances of H2CS are positively correlated with its column density, suggesting that the H2CS abundances are enhanced from cold cores, warm cores, and line-rich cores in star-forming regions.
Can Fallback Accretion on the Magnetar Model Power the X-Ray Flares Simultaneously Observed with Gamma Rays of Gamma-Ray Bursts?

Published: February 2024

The prompt emission, X-ray plateau, and X-ray flares of gamma-ray bursts (GRBs) are thought to be from internal dissipation, and the magnetar as the central engine with propeller fallback accretion is proposed to interpret the observed phenomena of GRBs. In this paper, by systematically searching for X-ray emission observed by Swift/X-ray Telescope, we find that seven robust GRBs include both X-ray flares and plateau emissions with measured redshift. More interestingly, the X-ray flares/bumps for those seven GRBs are simultaneously observed in the gamma-ray band. By adopting the propeller fallback accretion model to fit the observed data, it is found that the free parameters of two GRBs (140512A and 180329B) can be constrained very well, while in the other five cases, more or less, they are not all sufficiently constrained. On the other hand, this requires the conversion efficiency of the propeller to be two or three times higher than that of the spindown dipole radiation of the magnetar. If this is the case, it is contradictory to the expectation from the propeller model: namely, a dirtier ejecta should be less efficient in producing gamma-ray emissions. Our results hint that at least the magnetar central engine with propeller fallback accretion model cannot interpret very well both the GRB X-ray flares simultaneously observed in the gamma-ray band and the X-ray flares of GRBs with a high Lorentz factor.
An Improved Wiener Filtration Method for Constructing the Ensemble Pulsar Timescale
Authors: Zhang Zhehao , Tong Minglei , Yang Tinggao
Published: February 2024

An improved Wiener filtration (WF) method for constructing the ensemble pulsar timescale (EPT) is proposed to solve the existing problems in the WF algorithm. The improvements consist of three parts: (i) adjusting the cross-power spectral density (PSD) and PSD estimated by the weighted average (WA) algorithm by the concept of the energy upper limit; (ii) combining the cross-PSD and WA PSD to form a different signal modulus for the filtration of residuals of different noise levels; and (iii) setting a weight for each residual by a more general algorithm based on the concept of effective power. We use this improved WF method to construct the EPT by both simulated data and observational data from the second data release of the International Pulsar Timing Array. The results from the simulated data indicate this improved WF can successfully suppress the noise level and reform the common signal. For observational data, this method also successfully detects the fluctuations of International Atomic Time (TAI) and local atomic time TA(NTSC). A stability analysis shows that an EPT will have the potential to reveal the instability of TAI on a scale longer than 7 yr. This improved WF method can also be used to detect and monitor the noise in pulsar timing residuals inversely, by using multiple atomic time standards, which can in turn improve the EPT.

The tip of the tidal tail, resulting from an encounter between galaxies, features gas concentrations and some star-forming regions, such as tidal dwarf galaxies (TDGs). This region provides a unique laboratory for examining the star formation process in a dynamical environment distinct from that of disk galaxies. Using the Nobeyama 45 m telescope, we conducted 12CO(1−0) position-switching observations at the tips of the southern tidal tail in the Antennae galaxies. We detected CO emission not only from the two star-forming TDG candidates but also in regions with no significant star formation. Adopting a Galactic CO-to-H2 conversion factor without helium correction, the H2 gas surface density is ∼5–12 M
⊙ pc−2. In most regions, the molecular-to-atomic gas ratio is around unity (0.6–1.9), but we find a region with a high ratio with a 3σ lower limit of >7.2. The star formation efficiency (SFE) of molecular gas is notably low (<0.15 Gyr−1), indicating less active star formation than in both nearby disk galaxies (∼0.5–1.0 Gyr−1) and other TDGs previously observed. Including previous observations, the molecular gas SFEs vary widely among TDGs/tidal tails, from 10−2 to 10 Gyr−1, demonstrating significant variations in star formation activity. Potential factors contributing to the low SFE in the Antennae tail tips include extensive tides and/or the young age of the tail.

Objective

Vaccination against preventable infections is important for the management of rheumatic diseases (RDs). This study assessed the vaccination coverage and predictors among patients with RDs using real-world data from Israel.

Methods

This retrospective cross-sectional study, based on a Maccabi Healthcare Services database, included adult patients diagnosed with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and systemic lupus erythematosus (SLE), as of April 30, 2019. Age-specific vaccination coverage for influenza (past year), pneumococcal (23-valent pneumococcal polysaccharide vaccine [PPSV23] and/or 13-valent pneumococcal conjugate vaccine [PCV13]), and live-attenuated herpes zoster (HZ) vaccines (past 5 years) was reported. Logistic regression was used to investigate predictors of vaccination.

Results

The study included 14,528 patients (RA: n = 6932; PsA: n = 4395; SLE: n = 1951; > 1 condition: n = 1250). Influenza vaccine coverage among patients with RA, PsA, and SLE was 45.1%, 36.2%, and 33.7%, respectively. For PPSV23, corresponding rates were 19.6%, 16.2%, and 12.6%, respectively. In the elderly population (≥ 65 years), 63.2% had influenza vaccine in the past year and 83.4% had a PPSV23 vaccine in the past 5 years or at age ≥ 65. For PCV13 and HZ, coverage in the overall study population was low at 4.8% and 3.6%, respectively. Central residence and treatment with corticosteroids and biologic or targeted synthetic disease-modifying antirheumatic drugs within the past 5 years were significant predictors of vaccination coverage across all vaccines (P< 0.05). Other predictors varied by vaccine, including female sex (influenza, PPSV23, PCV13), age (influenza, PPSV23), chronic comorbidities (influenza, PPSV23, PCV13), shorter disease duration (PCV13), and high socioeconomic status (PCV13, HZ).

Conclusion

This study demonstrated suboptimal coverage of influenza, pneumococcal, and HZ vaccination in patients with RA, PsA, and SLE, in particular among younger adults in Israel.

Objective

Patient-initiated follow-up (PIFU) for rheumatoid arthritis (RA) is a model of care delivery wherein patients contact the clinic when needed instead of having regularly scheduled follow-up. Our objective was to investigate the influence of different patient eligibility characteristics on the number of potentially deferred visits to inform future implementation of a PIFU strategy.

Methods

We conducted a retrospective chart review of 7 rheumatologists' practices at 2 university-based clinics between March 1, 2021, and February 28, 2022. Data extracted included the type and frequency of visits, disease management, comorbidities, and care complexities. Stable disease was defined as remission or low disease activity with no medication changes at all visits. The influence of patient characteristics on the number of deferrable visits in patients with stable disease was explored in 4 criteria sets that were based on early disease duration, medication prescribed, presence of care complexity elements, and comorbidity burden.

Results

Records from 770 visits were reviewed from 365 patients with RA (71.5% female, 70% seropositive). Among all criteria sets, the proportion of visits that could be redirected varied between 2.5% and 20.9%. The highest proportion of deferrable visits was achieved when eligibility criteria included only stable disease activity and patients with RA on conventional synthetic disease-modifying antirheumatic drugs or no medications (n = 161, 20.9%).

Conclusion

PIFU may result in a more efficient use of specialist healthcare resources. However, the applicability of such models of care and the number of deferred visits is highly dependent on patient characteristics used to establish eligibility criteria for that model. These findings should be considered when planning implementation trials.

Objective

To conduct a systematic review of the effectiveness and safety of pharmacological treatments for adult-onset Still disease (AOSD).

Methods

Six databases, 2 trial registries, and conference abstracts were searched from January 2012 to February 2023 for studies of pharmacological interventions in people with AOSD. Outcomes were rates of remission and response, discontinuation of concurrent treatments, complications of AOSD, and treatment-related adverse events. Risk of bias was assessed with the Cochrane risk of bias tool and the Joanna Briggs Institute tool for case series.

Results

Forty-four studies evaluated treatments, including nonsteroidal antiinflammatory drugs (NSAIDs), corticosteroids (CS), conventional synthetic disease-modifying antirheumatic drugs (DMARDs), and biologic DMARDs (bDMARDs). For bDMARDs, tocilizumab (TCZ), anakinra (ANK), and canakinumab (CNK) had the most available data. Although 3 randomized controlled trials did not show statistically significant benefits of bDMARDs, metaanalyses showed high rates of complete remission and CS discontinuation. Complete remission was 80% (95% CI 59-92%,I236%), 73% (95% CI 58-84%,I266%), and 77% (95% CI 29-97%,I282%) and CS discontinuation was 57% (95% CI 29-81%,I266%), 47% (95% CI 18-78%,I279%), and 34% (95% CI 6-81%,I259%), respectively, for TCZ, ANK, and CNK. Studies with a higher proportion of patients previously treated with bDMARDs showed a trend toward lower rates of CS discontinuation (P= 0.05). The analyses had high clinical heterogeneity, largely because treatments were prescribed as different lines of therapy.

Conclusion

Evidence supports TCZ, ANK, and CNK therapy for AOSD. However, the magnitude of effect and comparative effectiveness of treatments is uncertain.
