Redescription and molecular phylogeny of Megalobatrachonema nipponicum Yamaguti, 1941 (Nematoda: Cosmocercoidea: Kathlaniidae)
Authors: Tsuchida Karin , Urabe Misako , Nishikawa Kanto 
Published: August 2024

Megalobatrachonema nipponicum Yamaguti, 1941 (Nematoda: Cosmocercoidea: Kathlaniidae), the type species of the genus Megalobatrachonema, had been only once reported from the Japanese giant salamander, Andrias japonicus (Temminck, 1836) (Amphibia: Cryptobranchidae), in the last 80 years. Herein, we reported the present species from A. japonicus and hybrids ( A. japonicus × Andrias davidianus (Blanchard, 1871)) following the original description. The examined specimens were morphologically identical to the original description. We showed the phylogenetic position of M. nipponicum among cosmocercoid species as well as among congeneric species, which suggested the polyphyly of the genus. In addition, the phylogenetic analysis did not support the subgenera in this genus. Thus, we considered the presence or absence of an esophageal bulb valve as a key morph to identify species, not subgenus, of Megalobatrachonema.
Exact ground states for pentagon chains with spin–orbit interaction
Authors: Gulacsi Zsolt 
Published: August 2024

Abstract
Exact ground states (GS) are deduced for conducting polymers possessing pentagon type of unit cell. The study is done in the presence of many-body spin–orbit interaction (SOI), local and nearest-neighbor Coulomb repulsion (CR), and presence of external E electric and B magnetic fields (EF). The simultaneous presence of SOI, CR, and EF in the exact conducting polymer GS is a novelty, so the development of the technique for the treatment possibility of such strongly correlated cases is presented in detail. The deduced GS show a broad spectrum of physical characteristics ranging from charge density waves doubling the system periodicity, metal–insulator transitions, to interesting external field-driven effects as, e.g., modification possibility of a static charge distribution by a static EF.

Cosmological constraints on a dynamical dark energy model in F(Q) gravity
Authors: Enkhili O. , Dahmani S. , Mhamdi D. , Ouali T. , Errahmani A. 
Published: August 2024

AbstractExtended teleparallel gravity, characterized by functionF(Q), whereQis the non-metricity scalar, is one of the most promising approaches to general relativity. In this paper, we reexamine a specific dynamical dark energy model, which is indistinguishable from the$$\Lambda $$ΛCDM model at the present time and exhibits a special event in the future, withinF(Q) gravity. To constrain the free parameters of the model, we perform Markov chain Monte Carlo (MCMC) analysis, using the last data from$$\hbox {Pantheon}^{+}$$Pantheon+and the latest measurements of the H(z) parameter, combined. On the basis of this analysis, we find that our dynamical dark energy model, in the context of F(Q) gravity, lies in the quintessence regime rather than in the phantom regime, as in the case of general relativity. Furthermore, this behavior affects the future expansion of the Universe, as it becomes decelerating at a$$1\sigma $$1σconfidence level for$$z<-0.5$$z<-0.5, showing a bounce at$$z_{\text {B}}\approx -0.835$$zB≈-0.835. We support our conclusion with a cosmographic analysis.

Comprehensive study of bouncing cosmological models in f(Q, T) theory
Authors: Gul M. Zeeshan , Sharif M. , Shabbir Shamraiza 
Published: August 2024

AbstractThe main objective of this article is to investigate the viability of bouncing cosmological scenarios using different forms of scale factors with perfect matter configuration in the framework of extended symmetric teleparallel theory. This modified proposal is defined by the function f(Q, T), where Q characterizes non-metricity and T denotes the trace of energy-momentum tensor. We investigate the modified field equations of this theory using different parametric values of the Hubble parameter and non-metricity to derive viable solutions. These solutions are relevant in various cosmological bounce models such as symmetric-bounce, super-bounce, oscillatory-bounce, matter-bounce and exponential-bounce models. Furthermore, we examine the behavior of energy density and pressure to analyze the characteristics of dark energy. A comprehensive analysis is also conducted to explore the behavior of the equation of state parameter and deceleration parameter to examine the evolutionary eras of the cosmos. Our findings show that the f(Q, T) gravity describes the cosmic expansion in the vicinity of the bouncing point during the early and late times of cosmic evolution.

Electrically charged black holes in gravity with a background Kalb–Ramond field
Authors: Duan Zheng-Qiao , Zhao Ju-Ying , Yang Ke 
Published: August 2024

AbstractWe derive the exact solutions for electrically charged black holes both in the absence and presence of a cosmological constant in the gravitational theory with Lorentz violation induced by a background Kalb–Ramond (KR) field. The corresponding thermodynamic properties are investigated. It is found that the standard first law of thermodynamics and the Smarr formula remain valid for the charged KR black holes. Nevertheless, the Lorentz-violating effect influences their ranges of local thermodynamic stability and the first- and second-order phase transition points. Furthermore, to examine the impact of Lorentz violation on the motion of test particles in the spacetime, we analyze the shadow and the innermost stable circular orbit (ISCO) of these black holes. Our results reveal that both the shadow and ISCO radii exhibit a high sensitivity to the Lorentz-violating parameter $$\ell $$

Camouflaging, internalized stigma, and mental health in the general population
Authors: Ai Wei , Cunningham William A. , Lai Meng-Chuan 
Published: August 2024

Background: Camouflaging, the strategies that some autistic people use to hide their differences, has been hypothesized to trigger mental health ramifications. Camouflaging might reflect ubiquitous impression management experiences that are not unique to autistic people and similarly impact the mental health of non-autistic people. Aims: We first examined whether individuals in the general population camouflage and manage impressions while experiencing mental health repercussions, and how gender and neurodivergent traits modified these associations. We then assessed how camouflaging and impression management arose from internalized stigma, and their inter-relationships in shaping mental health outcomes. Methods: Data were collected from 972 adults from a representative U.S. general population sample, with measures pertaining to camouflaging, impression management, mental health, internalized stigma, and neurodivergent traits. Multivariate hierarchical regression and moderated mediation analyses were used to address the two research aims. Results: Both camouflaging and self-presentation (a key component of impression management) were associated with mental health presentations in the general population, which overlapped with those previously reported in autistic people. These associations were more pronounced in women compared with men and were of different directions for individuals with higher autistic traits versus higher ADHD traits. Internalized stigma might be a key stressor that could elicit camouflaging and impression management through social anxiety, which in turn might lead to adverse mental health outcomes. Conclusions: These findings advance the conceptual clarity and clinical relevance of camouflaging and impression management across social and neurodiverse groups in the general population. The ramifications of camouflaging and impression management underscore the need to alleviate internalized stigma for better mental health across human groups.

Background In an effort to improve migraine management around the world, the International Headache Society (IHS) has here developed a list of practical recommendations for the acute pharmacological treatment of migraine. The recommendations are categorized into optimal and essential, in order to provide treatment options for all possible settings, including those with limited access to migraine medications. Methods An IHS steering committee developed a list of clinical questions based on practical issues in the management of migraine. A selected group of international senior and junior headache experts developed the recommendations, following expert consensus and the review of available national and international headache guidelines and guidance documents. Following the initial search, a bibliography of twenty-one national and international guidelines was created and reviewed by the working group. Results A total of seventeen questions addressing different aspects of acute migraine treatment have been outlined. For each of them we provide an optimal recommendation, to be used whenever possible, and an essential recommendation to be used when the optimal level cannot be attained. Conclusion Adoption of these international recommendations will improve the quality of acute migraine treatment around the world, even where pharmacological options remain limited.

Published: August 2024

Background: Anterior cruciate ligament injury and anterior cruciate ligament reconstruction (ACLR) are risk factors for symptomatic posttraumatic osteoarthritis (PTOA). After ACLR, individuals demonstrate altered joint tissue metabolism indicative of increased inflammation and cartilage breakdown. Serum biomarker changes have been associated with tibiofemoral cartilage composition indicative of worse knee joint health but not with PTOA-related symptoms. Purpose/Hypothesis: The purpose of this study was to determine associations between changes in serum biomarker profiles from the preoperative sample collection to 6 months after ACLR and clinically relevant knee PTOA symptoms at 12 months after ACLR. It was hypothesized that increases in biomarkers of inflammation, cartilage metabolism, and cartilage degradation would be associated with clinically relevant PTOA symptoms after ACLR. Study Design: Case-control study; Level of evidence, 3. Methods: Individuals undergoing primary ACLR were included (N = 30). Serum samples collected preoperatively and 6 months after ACLR were processed to measure markers indicative of changes in inflammation (ie, monocyte chemoattract protein 1 [MCP-1]) and cartilage breakdown (ie, cartilage oligomeric matrix protein [COMP], matrix metalloproteinase 3, ratio of type II collagen breakdown to type II collagen synthesis). Knee injury and Osteoarthritis Outcome Score surveys were completed at 12 months after ACLR and used to identify participants with and without clinically relevant PTOA-related symptoms. K-means cluster analyses were used to determine serum biomarker profiles. One-way analyses of variance and logistic regressions were used to assess differences in Knee injury and Osteoarthritis Outcome Score subscale scores and clinically relevant PTOA-related symptoms between biomarker profiles. Results: Two profiles were identified and characterized based on decreases (profile 1: 67% female; age, 21.4 ± 5.1 years; body mass index, 24.4 ± 2.4) and increases (profile 2: 33% female; age, 21.3 ± 3.2 years; body mass index, 23.4 ± 2.6) in sMCP-1 and sCOMP preoperatively to 6 months after ACLR. Participants with profile 2 did not demonstrate differences in knee pain, symptoms, activities of daily living, sports function, or quality of life at 12 months after ACLR compared to those with profile 1 ( P = .56-.81; η2 = 0.002-0.012). No statistically significant associations were noted between biomarker profiles and clinically relevant PTOA-related symptoms (odds ratio, 1.30; 95% CI, 0.23-6.33). Conclusion: Serum biomarker changes in MCP-1 and sCOMP within the first 6 months after ACLR were not associated with clinically relevant PTOA-related symptoms.
Decomposition and Dynamics of Unit Labor Costs in a Context of International Fragmentation of Production: Evidence from the German Automotive Sector
Authors: Gracia Santos Manuel , Montanyá Miguel , Paz María J. 
Published: August 2024

Conventional analysis has sought to explain the determinants of price competitiveness by way of national factors, but given the current degree of international fragmentation of production, a more holistic perspective needs to be explored. This document develops a specific proposal that permits the indicator on vertically integrated unit labor costs (VIULCs) to be broken down into its fundamental components; also, the evolution of this indicator is explored for the German automotive sector, to determine which component might best elucidate the evolution of the VIULCs. The results show a decrease in VIULCs deriving from the German sector as well as from its suppliers, confirming the relevant effects of outsourcing and offshoring strategies. Moreover, wage restraint among suppliers coupled with productivity gains are found to explain the overall reduction in VIULCs. JEL classification: P16, F15, F23,
The Saskatchewan Caregiver Experience Study: Support Priorities of Caregivers of Older Adults
Authors: Hall Steven , Rohatinsky Noelle , Holtslander Lorraine , Peacock Shelley 
Published: August 2024

Background Population aging is a global phenomenon. Many older adults living with chronic conditions rely on family and friend caregivers. The growing demand for family and friend caregivers underscores the necessity for adequate and effective support services. Purpose The Saskatchewan Caregiver Experience Study sought to gather the perspectives of caregivers of older adults and set priorities for caregiver support. Methods An online survey with open-ended questions was employed in this qualitative descriptive study. In this manuscript, we present our findings from the survey question: “What do you think is most important for support in your caregiving role? In other words, what are your top priorities for support?” Findings This survey question received n = 352 responses, evenly distributed across Saskatchewan in urban-large (33%), urban-small/medium (32%), and rural (35%) settings. Support priorities of Saskatchewan caregivers were found to be access to help when they need it; an ear to listen and a shoulder to lean on; assistance in optimizing the care recipient's health; having healthcare professionals that care; and improved policies, legislations, and regulations. Conclusion Services and interventions that assist caregivers are more likely to be accessed and utilized when caregivers are given the opportunity to identify their own support priorities. This study has the potential to inform health and governmental systems to support caregivers of older adults provincially within Saskatchewan, nationally in Canada, and in a global context.
Moral resilience and intention to leave: Mediating effect of moral distress
Authors: KOVANCI Mustafa Sabri , ATLI ÖZBAŞ Azize 
Published: August 2024

Aims This study aims to examine the mediating effect of moral distress on the relationship between moral resilience and the intention to leave. Background Moral distress is a phenomenon that negatively impacts healthcare workers, healthcare institutions, and recipients. To eliminate or minimize the negative effects of moral distress, it is necessary to increase the moral resilience of nurses. Moral resilience is important in protecting against the negative effects of moral distress, such as burnout and turnover intention. In this direction, it is necessary to increase the moral resilience of nurses to reduce negative situations such as turnover intention in nurses. Methods It is a descriptive–predictive study. Sociodemographic Information Form, Measure of Moral Distress – Healthcare Professionals, and Rushton Moral Resilience Scale were used to collect data from the nurses. A total of 220 clinical nurses were recruited. Ethical considerations Approval was obtained from the university’s non-interventional ethics committee, and informed consent was obtained from the participants. Results The study found a total moral distress score of 6.39 ± 0.3.12 and moral resilience score of 2.69 ± 0.48. A moderate and weak negative correlation was found between moral distress and moral resilience. Moral distress has a moderating effect on the intention to leave nursing (β = −0.158, p = .010) and the intention to leave the current position (β = −0.174, p = .000). Individual’s moral resilience directly affects the intention to leave. The presence of moral distress eliminates the direct effect of moral resilience and affects the intention to leave together with moral resilience. Conclusions Moral resilience leads to decreased intention to leave, and moral distress mediates this situation. An increase in moral distress decreases moral resilience and increases intention to leave. It can be assumed that if moral distress is not controlled, increasing moral resilience will not affect the intention to leave the job.

Published: August 2024

Background Newborn screening (NBS) programs are employed to detect various disorders with the aim of early identification and scope for early intervention. They are increasingly being accepted by parents in many countries. Aim The aim of this study is to know about the awareness of NBS programs among parents and gain knowledge about their perspectives on and experiences with the screening program. Settings and Design This is a cross-sectional study done over a period of three months among parents of newborns who underwent the NBS program in a tertiary care teaching center in South India. Material and Methods The demographic details, awareness of parents regarding NBS, and their experiences during the procedure were recorded using a pretested and piloted questionnaire, and the results were analyzed. Statistical Analysis Used Frequencies and percentages were used for descriptive statistics. Chi-square test or Fisher’s exact test was used for finding an association between nominal variables. Results We found that the awareness about NBS programs is very low 14% (95% CI: 8.5–22.1) among parents in the studied population. There are multiple concerns among parents such as cost involved, the diseases screened, the method of sampling, interpretation of results, and further management options. Conclusion In spite of high literacy and good socioeconomic status, awareness is low among parents about the NBS program.
High incidence of femoroacetabular impingement deformity in bi-column acetabular fractures
Authors: Bartlett Gavin E , Stephens Alastair S , Norton Mark R , Darren Fern Edwin 
Published: August 2024

Introduction: Dynamic interaction of cam and pincer deformities can result in pathological contact forces in femoroacetabular impingement (FAI) syndrome. Similar deformities were noted during acetabular fracture reconstruction. We hypothesise that the prevalence of FAI deformity is higher in patients sustaining acetabular fractures than in a control group. Methods: This retrospective radiographic study compared the parameters that define FAI deformity in 100 patients consecutively admitted to a trauma unit with an acetabular fracture and a control group of 100 patients with lateral compression pelvic fracture without acetabular injury. Both underwent identical clinical imaging. Centre-edge angles (CEA) and alpha angles were used to define patients with pincer, cam, or mixed FAI deformity. Results: There were significantly more patients with FAI deformity in the acetabular fracture group than in the control group (71% vs. 18%, p < 0.0001). There were considerably more fractures involving both anterior and posterior acetabular columns in patients with ‘pincer’ sockets ( p = 0.02, OR = 2.95, 95% CI, 1.12–7.78). Conclusions: There is a high prevalence of cam and pincer deformities in patients with acetabular fractures, particularly bi-column fractures.
