Addressing gaps in pain research from an integrated whole person perspective

Abstract While our understanding of pain is rapidly growing, some areas of pain research are lagging behind. This article discusses two current and inter-related gaps in knowledge that are in need of addressing: first, the connections between “brain” and “body” components of pain; and second, the process of endogenous pain resolution. Historical reasons for these research gaps are discussed and solutions are outlined based on an integrative, whole person research approach. These include comprehensive mapping of the mechanosensory and nociceptive innervation of deep tissues; developing objective, non-invasive measurements to quantify the metabolic, structural and mechanical components of the peripheral tissue environment; integrating our understanding of pain pathophysiology, across whole organs and whole body, as well as across bio-psycho-social domains; and understanding the interplay of nervous system and peripheral tissue mechanisms that promote the endogenous resolution of pain and prevent its acute-to-chronic transition. Current NIH-led efforts in these areas are outlined, including several studies within the NIH HEAL (or Help End Addition Long Term) initiative and the National Center for Complementary and Integrative Health's strategic priorities in whole person research.

Circulating Angiopoietin-2 (Angpt2) levels predict diagnosis of Chronic Thromboembolic Pulmonary Hypertension (CTEPH)

Abstract Background Vascular remodeling following incomplete thrombus resolution is considered to be a key factor in the progression to chronic thromboembolic pulmonary hypertension (CTEPH) after acute pulmonary embolism (PE). Recent data demonstrated that Angpt2, which controls signaling via the Tie2 receptor, could interfere with the normal process of thrombus resolution. Our prior findings have shown that patients presenting with acute PE and having plasma levels of Angt-2 ≥5.5 ng/ml at admission are at a significantly increased risk (93 times higher) of being diagnosed with CTEPH in subsequent assessments. Purpose To externally validate the prognostic performance of Angpt2 for the development of CTEPH. Methods In a prospective cohort study of unselected consecutive all-comers with PE, survivors of the index acute event underwent 3-, 12- and 24-month follow-up with venous blood sampling for subsequent biomarker measurements. Angpt2 was measured on admission using specific enzyme linked immunosorbent assays (ELISA) detecting both the endogenous and the recombinant protein, according to the manufacturer (R&D Systems). Results Overall, 319 patients with acute PE (median age: 62 [IQR, 50-73]; females: 55.2%) were included in the analysis with a median Angpt2 plasma level of 2.6 ng/ml (IQR, 1.8-3.7) (Figure 1). Patients with PE and Angpt-2 plasma levels above the median had more often comorbidities, such as chronic heart failure (24.2% and 11.0.%; p=0.045), chronic kidney disease (33.3% vs 14.0%; p=0.010), or diabetes (27.3% vs. 12.9%; p=0.032). Angpt2 plasma levels correlated with haemodynamic status and parameters indicating severe PE (right ventricle dysfunction, r=0.129 [p=0.021) and troponin, r=0.246 [p<0.001]). In total, post-PE impairment (PPEI) was diagnosed in 33 (10.3%) and CTEPH in four (1.3%) patients during follow-up. Angpt2 plasma levels were higher on admission in patients developing PPEI or CTEPH during follow-up compared to patients without PPEI or CTEPH (PPEI vs non-PPEI: median, 3.2 [2.3-4.1] ng/ml vs. 2.5 [1-3.4] ng/ml, p=0.035; CTEPH vs. non-CTEPH: median, 5.1 [2.9-10.5] ng/ml vs. 2.5 [1.7-3.6] ng/ml, p=0.055). Regarding the diagnosis of CTEPH during follow-up, ROC analysis illustrated an AUC for Angpt2 (0.779 [95% CI 0.56–0.99]; p=0.055]) (Figure 2). By using univariate logistic regression analysis, the calculated predefined Angpt2 cut-off value of ≥5.5 ng/ml was associated with a 9.2-fold increased risk (1.3–67.4, p=0.030) for a diagnosis of CTEPH during follow-up. Conclusion We were able to validate in a different patient cohort the usefulness of Angpt2 as a novel biomarker to identify patients at risk for CTEPH.

THE EVOLVING LANDSCAPE OF INVESTOR PROTECTION: BALANCING STATE SOVEREIGNTY AND INVESTOR RIGHTS IN THE 21ST CENTURY

The evolving landscape of investor protection in the 21st century requires a delicate balance between safeguarding investor rights and preserving state sovereignty. As global investments expand, investors seek legal assurances to protect their assets, while states must retain the ability to regulate in the public interest, addressing economic, social, and environmental challenges. This tension has sparked debates about the role of investor-state dispute settlement (ISDS) mechanisms and the need for reform. By modernizing investment treaties and dispute resolution processes, the international community can create a more equitable system that fosters both investment and sustainable development, ensuring mutual benefits for investors and states alike.

Подход Австрии к урегулированию конфликта в Сирии

Since the early 1990s, the Republic of Austria has consistently expanded the geographical and instrumental scope of its military-political agenda. One of the key directions of this course has been the country’s participation in the resolution of the crisis in the Syrian Arab Republic during the 2010s. This article examines the evolution of Austria’s approach to stabilizing the situation in Syria from 2011 to the early 2020s. The author highlights the crucial determinants that influenced the country’s support for measures against the legitimate government of Bashar al-Assad between 2011 and 2014. The main reasons for the shift in this policy in the mid-2010s are reflected, with particular emphasis on the factor of the intensification of international terrorism and the role of the Russian Federation in combating it. The article presents Austria’s diplomatic efforts to navigate its position and that of the European Union as a whole, aiming to prevent their marginalization in the Syrian resolution process by the end of the 2010s.

Does vibrotactile biofeedback for postural control interfere with cognitive processes?

BackgroundDirectional vibrotactile biofeedback for balance control can be instructed in the form of Repulsive (to move in the opposite direction of vibrations) or Attractive (to move in the direction of vibrations) stimulus encodings. However, which of these encodings is less cognitively demanding and poses less interference with high-level cognitive processes of conflict resolution remains unresolved.MethodsIn two between-subject studies with 30 (16 females) and 35 (23 females) healthy young adults, respectively, we investigated the cognitive load of Attractive and Repulsive vibrotactile biofeedback on 1) working memory (Study I) and 2) cognitive conflict resolution (Study II). Both studies also examined the effectiveness of both feedback stimulus encodings on balance control during quiet standing with eyes closed.ResultsBoth Attractive and Repulsive vibrotactile biofeedback increased balance stability (reduced trunk sway variability) in both the working memory and the conflict resolution study (Study I and II, respectively) with a greater increase of stability for the Repulsive encoding during multitasking demanding cognitive conflict resolution (Study II). Cognitive costs, measured in terms of the Linear Integrated Speed-Accuracy Score (LISAS), were greater for the Attractive encoding during multitasking with working memory demands. When cognitive conflict resolution was required as a secondary cognitive task, both stimulus encodings increased cognitive costs equally.ConclusionsThe effects of instructed Repulsive and Attractive stimulus encodings for the response-related interpretation of vibrotactile biofeedback of body sway were contrasted with respect to cognitive processing demands and balance stabilisation benefits. Both encodings improved balance stability but at certain cognitive costs. Regarding interference with specific high-level cognitive processes, however, a distinction has to be made between both encodings. Repulsive feedback encoding seems to cause less cognitive costs on working memory load and slightly greater stabilisation when cognitive conflict resolution is required. These results are discussed in the context of the known benefits of avoidance actions on cognitive control.

Dual Signature of Chirality Induced Spin Selectivity through Spontaneous Resolution of 2D Metal‐Organic Frameworks

The Chiral‐Induced Spin Selectivity (CISS) effect has emerged as a fascinating phenomenon within the realm of electron’s spin manipulation, showcasing a unique interplay between electron’s spin and molecular chirality. Subsequent to its discovery, researchers have been actively involved in exploring the new chiral molecules as effective spin filters. In the realm of observing the CISS effect, the conventional approach has mandated the utilization of two distinct enantiomers of chiral molecules. However, this present study represents a significant advancement by demonstrating the ability to control both spin states of electrons in a single system. In this work, we have demonstrated the preparation of chiral metal‐organic frameworks (MOFs) via a "spontaneous resolution" process, obviating the requirement for chiral sources. Remarkably, this work signifies the first instance of achieving dual signature of spin selectivity from a single and exclusively achiral system through a spontaneous resolution process. This holds immense potential as it facilitates the production of two distinct spin‐filtering materials from a unified system. In overall, the significant findings achieved using these robust and easily synthesized MOF crystals without the requirement for chiral medium represent a crucial advancement in enhancing the effectiveness of spin filtering materials to produce spintronic devices.

Advancing Diagnostic Accuracy and Quality of Patient Care Through the Implementation of a Flow Cytometry Quality Assurance Program

Abstract Introduction/Objective Flow cytometry immunophenotypic analysis plays an important role in the diagnosis, classification and disease monitoring of hematological neoplasms. However, interpretation of flow cytometry testing can be challenging, especially when using highly complex antibody panels. Thus exploring ways to improve diagnostic accuracy and in turn improving quality of patient care is needed. Methods/Case Report A flow cytometry quality assurance (QA) program was developed. Cases from various complex flow cytometry panels were randomly selected and cross-reviewed by a second pathologist on a daily basis. The outcomes of the QA review were categorized into three groups: complete agreement, minor discrepancy and major discrepancy. Each discrepancy, once identified, underwent a process of documentation, discussion and resolution. The reports were then modified in a timely manner and the clinical teams were notified of the changes. Recurrent issues and common pitfalls were reviewed and discussed at a weekly QA meeting. Here we summarize our 3-years’ experience with this program. Results (if a Case Study enter NA) In total, 6,166 cases were evaluated by the QA program; 6,028 (97.7%) cases showed complete concordance, 120 (2.0%) cases showed minor discrepancies and 18 (0.3%) cases showed major discrepancies. Antibody panels designed to evaluate mature and immature T-cell abnormalities showed the highest rate of discrepancy, 2.8%, whereas panels designed for evaluation of myelodysplastic syndromes showed the lowest discrepancy rate, 1.7%. When analyzing the trends of concordance and discrepancy over time, we found a statistically significant decrease in discrepancies over time, from 4% at the beginning of the QA program to 1.5% in the most recent time interval. Conclusion The overall concordance rate was 97.7%. The remaining 2.3% cases showed discrepancies that required a correction, underscoring the value and necessity of having a QA program. The overall discrepancy rates exhibited a gradual decline over time, indicative of the positive impact of the QA program on enhancing diagnostic competency and accuracy over time.

Adaptive IMU error correction algorithm for dual-antenna GNSS/IMU integrated vehicle attitude determination

Abstract The attitude of a vehicle can be largely determined by integrating the global navigation satellite system (GNSS) and inertial measurement unit (IMU) in land-based applications. However, traditional dual-antenna GNSS/IMU integrated systems are susceptible to signal reflection, diffraction, and even interruption, leading to reduced accuracy and reliability in challenging environments. To address this issue, this paper proposes an adaptive IMU error correction algorithm for dual-antenna GNSS/IMU integrated vehicle attitude determination. First, we propose an IMU-aided baseline length constraint model to support the ambiguity resolution (AR) process. This model incorporates accurate prior information from the IMU, improving the success rate of AR within the dual-antenna GNSS/IMU integrated system. Second, we present an adaptive IMU error correction mechanism based on long short-term memory (LSTM) and particle swarm optimization (PSO) to assist in vehicle attitude determination and mitigate attitude error drift of the lMU during GNSS outages. Field test results verified that, compared to two other candidate algorithms, the proposed algorithm improves accuracy in roll, pitch, and yaw by 19.23%, 30.56%, and 67.12%, respectively, and by 12.50%, 10.71%, and 38.39% respectively. Moreover, in two distinct scenarios where GNSS is blocked for 120 seconds, the proposed algorithm still provides accurate and stable attitude information for vehicle navigation, with the accuracy of roll, pitch, and yaw kept within 0.08 degrees.

How Does an Audit Committee That Encourages Perspective Taking Impact Auditor and Client Judgments During Accounting Disagreements?

SUMMARY We summarize the published study “The Influence of Perspective Taking Encouraged by the Audit Committee on Auditor and Client Judgments during Accounting Disputes” (Bhattacharjee, Moreno, and Pyzoha 2020), which examines the impact of an audit committee (AC) that assists in a disagreement by encouraging the auditor and client to consider their counterpart’s perspective throughout a multiple-stage resolution process. The authors find that an AC that encourages perspective taking compared with an AC that does not leads to a higher likelihood of agreement between the auditor and the client. The AC’s approach continues to impact the parties’ behavior after the AC provides a resolution recommendation. The findings have important implications for practitioners, policymakers, and regulators regarding the critical role of the AC in disagreement resolution.

EFFECTIVENESS OF BUSINESS DISPUTE RESOLUTION THROUGH MEDIATION IN INDONESIA

This study investigates the effectiveness of mediation as a mechanism for resolving business disputes in Indonesia, focusing on its procedural efficiency and impact on the relationships between disputing parties. Employing a qualitative research approach with descriptive normative analysis, the research highlights the legal foundations of mediation established by laws such as Law No. 30 of 1999 and Supreme Court Regulation No. 1 of 2016, which mandate mediation prior to litigation. The findings reveal that while mediation presents significant benefits, including faster resolution times and cost savings, its effectiveness is contingent on several factors: public awareness, the quality of mediators, and the parties' willingness to engage collaboratively. The study emphasizes the importance of confidentiality, neutrality, and mutual interest as key principles in ensuring a fair mediation process. Despite the challenges faced, such as a preference for litigation and uncertainties regarding the enforcement of mediated agreements, the research indicates that mediation has the potential to enhance business relationships and streamline dispute resolution processes. The insights gleaned from this study not only contribute to the understanding of mediation within the Indonesian legal context but also offer valuable lessons for other jurisdictions aiming to develop their alternative dispute resolution frameworks.

Adaptive strategies for investor-state arbitration: A framework for emerging economies to safeguard national interests and attract investment

In the realm of international investment, Investor-State Arbitration (ISA) plays a crucial role in resolving disputes between investors and states. Emerging economies often face unique challenges in this context, balancing the need to attract foreign investment with the imperative to safeguard national interests. This review presents a framework for adaptive strategies designed to help emerging economies navigate the complexities of ISA while optimizing both investment attraction and national protection. The framework emphasizes a dual approach: enhancing the attractiveness of a country for foreign investors and fortifying mechanisms to protect national interests. Key components of the framework include the development of robust legal and regulatory environments that align with international standards while accommodating national priorities, and the adoption of transparent and equitable dispute resolution processes. The framework advocates for the integration of tailored dispute resolution clauses in investment treaties that consider the specific needs and vulnerabilities of emerging economies. Additionally, it recommends the establishment of dedicated institutions and expertise to manage ISA effectively, ensuring that states are well-prepared to address and resolve disputes. Emphasis is placed on proactive engagement in treaty negotiations, leveraging strategic partnerships, and fostering dialogue with investors to create a balanced and mutually beneficial investment climate. The review also highlights the importance of continuous review and adaptation of legal frameworks to respond to evolving global standards and investment trends. By implementing these adaptive strategies, emerging economies can enhance their attractiveness as investment destinations while safeguarding their sovereignty and national interests. The proposed framework provides a comprehensive approach to managing ISA, balancing the imperative of attracting investment with the need to protect national resources and regulatory autonomy.

The Adoption of a “Diseased Identity” in Traditional 12-Step Groups: Exploring the Implications of These Processes for Individuals and Practitioners in Health and Social Care Services

Self-help groups are increasingly utilised by communities of interest and shared experience, services, and government departments as platforms for supporting and improving health and social care outcomes for drug and alcohol users. Traditional 12-step self-help groups like Narcotics Anonymous and Alcoholics Anonymous (NA and AA) are worldwide organisations and each have their own programme of change, language, criteria for membership, processes for problem resolution, and self-transformation. Within these types of groups, members are openly encouraged to identify with and adopt an (diseased) identity that is consistently invoked to work on the self. In the self-help recovery literature, it is widely recognised that individuals can benefit by thinking about themselves as “diseased” and then acting and behaving in a manner which is congruent with their reframed “identity”. Less is known about the processes involved in this and social-, psychological-, and health-related implications for individuals in drug- and alcohol-specific self-help groups. A thematic analysis of data from (n-36) in-depth qualitative interviews with long-term (6 months–10 years) self-help users identified four themes associated with the adoption of a diseased identity and self-help group processes: (1) normalising the disease and illness; (2) identifying as diseased; (3) living as a diseased individual; and (4) one addict helping another addict. The results of this research should not be interpretated as a critique of the 12-step approach or groups. Instead, it should be recognised that whilst improvements to individual wellbeing are reported, identifying as diseased can exacerbate negative self-perceptions that individuals hold about themselves, their character, capabilities, and ability. Being diseased, accepting disease, and identifying as diseased also has the potential to inhibit their engagement with wider social networks and professional services outside of their own fellowship or group. We conclude this paper by exploring the implications of a “diseased identity” and self-help processes for individuals who access self-help groups, and health and social care practitioners who support self-help users as they engage with services and self-help groups.

Factors Militating against the Efficacy of the Mutual Agreement Procedure: A Comparison between South Africa, Kenya, Uganda and Ghana

The effective resolution of transfer pricing disputes has been identified as one of the primary challenges to eliminate double taxation and/or double non-taxation as well as to enhance the free flow of trade and investment. This article investigates the unique challenges faced by selected African countries, including South Africa, Kenya, Uganda and Ghana, which militate against the use of the mutual agreement procedure (MAP) as a preferred Organisation for Economic Co-operation and Development (OECD) transfer pricing dispute resolution mechanism. The research used a qualitative legal review of existing literature in the selected regimes by comparing the domestic tax law framework in these countries. Transfer pricing manipulation is a significant source of illicit financial flows of capital as identified in the research by Global Financial Integrity on Africa, which drew from Ghana, Kenya and Uganda as case studies. South Africa and Kenya are considered as the gateways to Africa with many multinational enterprises (MNEs) taking residence in them before expanding to the rest of Africa. The article focuses specifically on a number of guidelines that should be in place for the effective use of the MAP in the resolution of tax treaty disputes. It also demonstrates how the absence of guidelines, or the lack of clarity thereof, discourages both taxpayers and revenue authorities from effectively using the MAP to resolve transfer pricing disputes. The absence of guidelines has resulted in many aggrieved taxpayers opting to approach the courts as opposed to using the MAP as a mechanism to resolve tax treaty disputes. Furthermore, it highlights the importance of how resolved transfer pricing disputes eliminates double taxation. The article recommends that the same benefits enjoyed under the domestic dispute resolution process be incorporated into the MAP. It also makes recommendations on how jurisdictions with a low tax treaty network can address this challenge to enable them to effectively use the MAP as a tax treaty dispute resolution.

Shamans and “Dark Agencies”: War, Magical Parasitism, and Re-Enchanted Spirits in Siberia

Alleged practices of magical assault and vampirism are a recurrent feature of popular explanations of misfortune in Tuva, South Siberia. Based on a field study of healing practices in an “Association of Shamans”, this article analyses rituals of redressing curse afflictions in the context of Russian political domination. A central purpose of this discussion is to foreground the centrality of kinds of parasitical worship and occult threat to structures of political power in—and beyond—the territory of Tuva. Focusing on a “cursescape”, which develops from the combative practices of shamans, occult specialists, and office-holders, the article probes a repertoire of shamanic healing symbols. It is argued that healing efficacy is constructed in the process of engaging with hunting symbols and animal spirits, which appear in Indigenous Siberian cosmologies. The analysis shows that ideas of ritual risk underpin the process of symbolic resolution. Whereas shamanic practices provide refuge to spirits evicted from their natural landscapes, Tibetan Buddhism—the unifying religion of Tuva—offers an alternative path of healing the effects of the shamans’ propagation of spirits. The article highlights indigenous perceptions of a “cursed” landscape as a space where the agencies of “darkness” and their political sponsors are confronted with an emancipating religious modality emerging from local Buddhist rituals. The analysis displays the unsolved drama of itinerant spirits and shamanic ancestral souls, whose agency is revealed through successive—yet inauspicious—forms of reincarnation.

Research on the Energy Management Strategy of a Hybrid Tractor OS-ECVT Based on a Dynamic Programming Algorithm

The multi-degree-of-freedom characteristics of the planetary gear electronic continuously variable transmission (ECVT) configuration in series-parallel hybrid tractors impose more complex requirements for energy management strategies under variable load conditions. For a high-power hybrid tractor, this paper takes the hybrid tractor output-split (OS)-ECVT configuration as the research object and describes the principles of stepless transmission and power-splitting within the configuration. In order to improve the fuel economy of high-power hybrid tractors and the running status of power components, an energy management strategy focused on ploughing conditions based on the Bellman minimum dynamic programming (DP) algorithm is proposed in this paper. Second, equivalent fuel consumption is selected as the performance index for energy-saving control, and the solving principle of the energy management strategy based on the dynamic programming algorithm is established to facilitate the resolution process of the energy management strategy. Finally, the energy-saving control simulation is completed under ploughing conditions. The results show that compared with the energy management strategy based on the optimal operating line (OOL), the energy management strategy based on DP fully utilizes the benefits of low-cost electric energy and enables the hybrid power system to have a wider range of stepless transmission performance. In addition, the hybrid power system has the advantages of enhanced decoupling of speed and torque, higher efficiency, and more economical secondary energy conversion. As a result, the whole machine has enhanced power-split performance, greatly improving the running conditions of the power components. The equivalent fuel consumption values of the energy management strategies based on DP and OOL are about 3.1238 L and 4.2713 L, respectively. The equivalent fuel consumption based on DP is reduced by about 26.87%, which effectively improves the fuel efficiency of hybrid tractors.
