AbstractThe Qieganbulake deposit associated with a mafic–ultramafic–carbonatite complex in the Kuluketage block is not only the world’s second-largest vermiculite deposit, but also a medium-size carbonatite-related phosphate deposit. Field observations, radiometric dating results and Sr–Nd–Hf isotopes reveal that the parental magmas of the carbonatite and mafic–ultramafic rocks are cogenetic and formed synchronously at c. 810 Ma. Geochemical characteristics and Sr–Nd–Hf–S isotopes ((87Sr/86Sr)i = 0.70581–0.70710; ϵNd(t) = −0.20 to −11.80; ϵHf(t) = −7.5 to −10.3; δ34S = +0.7 ‰ to +3.0 ‰ (some sulfides with high δ34S values (+3.2 to +6.6) were formed by late hydrothermal sulfur)), in combination with mineral compositions and previous research, strongly indicate that the Qieganbulake mafic–ultramafic–carbonatite complex formed via extensive crystal fractionation/cumulation and liquid immiscibility of a carbonated tholeiitic magma, possibly derived from partial melting of an enriched subcontinental lithospheric mantle previously modified by slab-released fluids and sediment input in a continental rift setting. The coupled enriched Sr–Nd isotopic signatures, in combination with previous research, suggest that the enriched subcontinental lithospheric mantle could have been metasomatized by asthenospheric mantle melts to different degrees. The Qieganbulake carbonatite-related phosphate ores were the products of normal fractional crystallization/cumulation of P–Fe3+ complex enriched carbonatite magma in high oxygen fugacity conditions, which was generated by liquid immiscibility of CO2–Fe–Ti–P-rich residual magma undergoing high differentiation.

ABSTRACTAcross several African countries, birth preparedness and complication readiness (BPACR) among pregnant women is poor. The practice of BPACR, though improving in recent years, is not commensurate with the knowledge available to pregnant women. Maternal health indices remain sub-optimal. This study evaluates the determinants of this “know-do’ gap among women receiving antenatal care at a secondary health facility in Benin City, Nigeria. A cross-sectional study involving 427 pregnant women was conducted between October and December 2020 using a structured interviewer-administered questionnaire. The prevalence of knowledge and practice were described, and the determinants of BPACR practice evaluated using bivariable (chi-square) analysis and multivariable ordinal logistic regression with post-estimation predictive margins analysis. About 77% of respondents had good birth preparedness practice. Multivariable regression revealed that respondents with poor knowledge and moderate knowledge of components of BPACR had statistically significant lower odds (OR:0.05 (95% CI: 0.02-0.13) and 0.10 (95% CI: 0.03-0.30) times, respectively) for greater practice of BPACR when compared to those with good knowledge. Respondents with poor knowledge of danger signs had statistically significant lower odds (OR: 0.08 (95% CI: 0.03-0.26) for greater practice of BPACR when compared to those with good knowledge. But predictive margins analyses demonstrates that knowledge, though critical to practice, is insufficient to optimize practice. The optimum number of danger signs women need to know to improve practice may be between eight to ten. Beyond this number, practice may not change significantly. Other predictors of BPACR practice include income level, parity, gravidity, and residential settings. The number of antenatal clinic visits had no statistically significant correlation with BPACR practice. Interventions to facilitate practice at the community level may be helpful to improve outcomes and bridge the know-do gap with respect to BPACR within the study context.
Quantifying use of kelp forest habitat by commercially important crustaceans in the United Kingdom
Authors: Smale Dan A. , King Nathan G. , Jackson-Bué Mathilde , Moore Pippa J. 
Published: January 2023

AbstractKelp forests are regarded as important nursery and foraging habitats for commercially important species of finfish and shellfish despite an absence of fishery-independent data in many regions. Here, we conducted targeted surveys at 12 subtidal reefs, distributed across 9° of latitude in the UK, using three complementary techniques (Underwater Visual Census (UVC), Baited Remote Underwater Video (BRUV) and deployment of prawn pots) to quantify the abundance of crustaceans within kelp forests. Commercially important species were recorded at all sites; Cancer pagurus (brown/edible crab) and Necora puber (velvet swimming crab) were the most abundant and commonly observed, although Maja brachydactyla (spider crab), Homarus gammarus (European lobster) and Palaemon serratus (common prawn) were also recorded. The abundance of some species exhibited pronounced regional variability, with higher abundances of C. pagurus within northern regions and, conversely, higher abundances of M. brachydactyla and P. serratus within southern regions. Each sampling technique yielded similar spatial patterns for the most abundant species but had varying sensitivity to some species. Most individuals observed were juvenile or sub-adults, suggesting kelp forests serve as important nursery grounds for commercially and ecologically important crustaceans. Further monitoring efforts, conducted across greater spatiotemporal scales and in different habitat types, are needed to provide a robust baseline against which to detect changes and to inform management and conservation actions.
First mitochondrial genome of a lugworm (Annelida: Arenicolidae) and its phylogenetic position
Authors: Kobayashi Genki , Itoh Hajime , Nakajima Nobuyoshi 
Published: January 2023

AbstractThe annelid mitochondrial genomes (mitogenomes) have been well documented, and phylogenetic analyses based on the mitogenomes provide insightful implications for annelid evolution. However, the mitogenomes of some families remain unknown. Herein, we determined the complete mitogenome of the lugwormAbarenicola claparedi oceanica(15,524 bp), representing the first mitogenome from the family Arenicolidae. The gene order of this species is the same as the various lineages in Sedentaria. The maximum likelihood phylogenetic analyses were performed based on six different datasets, including 43 ingroups (oligochaetes, hirudineans, echiurans and closely related polychaetes) and two outgroups (Siboglinidae), namely, aligned and trimmed datasets consisting of the nucleotide sequences of protein-coding genes (PCGs) and rRNAs, and amino acid sequences of PCGs. Phylogenetic analyses based on the nucleotide sequences yielded trees with better support values than those based on the amino acid sequences. Arenicolidae is clustered with Maldanidae in all analyses. Analyses based on nucleotide sequences confirm the monophyly of Terebellidae, which was paraphyletic in recent mitogenomic phylogenetic studies. We also performed the phylogenetic analysis based on the RY-coding of the nucleotide sequences of PCGs only to yield phylogeny with generally low support values. Additional mitogenome sequences of related ingroup species would be needed to comprehensively understand the phylogenetic relationship, which was not present in this study.
Socialistic 3D tracking of humans from a mobile robot for a ‘human following robot’ behaviour
Authors: Malviya Vaibhav , Kala Rahul 
Published: January 2023

AbstractRobotic guides take visitors on a tour of a facility. Such robots must always know the position of the visitor for decision-making. Current tracking algorithms largely assume that the person will be nearly always visible. In the robotic guide application, a person’s visibility could be often lost for prolonged periods, especially when the robot is circumventing a corner or making a sharp turn. In such cases, a person cannot quickly come behind the limited field of view rear camera. We propose a new algorithm that can track people for prolonged times under such conditions. The algorithm is benefitted from an application-level heuristic that the person will be nearly always following the robot, which can be used to guess the motion. The proposed work uses a Particle Filter with a ‘follow-the-robot’ motion model for tracking. The tracking is performed in 3D using a monocular camera. Unlike approaches in the literature, the proposed work observes from a moving base that is especially challenging since a rotation of the robot can cause a large sudden change in the position of the human in the image plane that the approaches in the literature would filter out. Tracking in 3D can resolve such errors. The proposed approach is tested for three different indoor scenarios. The results showcase that the approach is significantly better than the baselines including tracking in the image and projecting in 3D, tracking using a randomized (non-social) motion model, tracking using a Kalman Filter and using LSTM for trajectory prediction.

Abstract

Objectives
The aim of this study was to assess the effect of the wearable cardioverter-defibrillator (WCD) on patient-reported outcomes (PRO) in adult patients with high risk for sudden cardiac arrest.

Methods
We performed a systematic literature search in Medline (via PubMed) and Cochrane Library in February 2022 and included studies with a study population ≥18 years and prescribed WCD. PRO include health-related quality of life (QoL), symptoms, utilities, or satisfaction ratings. Study selection was done by two reviewers independently using predefined inclusion and exclusion criteria. Quality assessment of studies as well as data extraction was performed by one author and approved by a second author. Results of the included studies are presented quantitatively.

Results
One randomized controlled trial (RCT), one comparative non-randomized trial, and three single-arm trials were included. QoL was assessed in four studies, but with different assessment tools. One study additionally evaluated the change in depressive symptoms and anxiety and one study focused on acceptability of WCD but evaluated items that are closely related to QoL. Results of the RCT show no statistically significant difference in QoL assessed by SF-36 and EQ-5D comparing WCD and Guideline-Directed Medical Therapy (GDMT) versus GDMT alone. One comparative study reports an improvement in depressive symptoms and anxiety within groups but no significant difference between groups. Further, one single-arm study reported improvement in QoL between baseline and day 90 and day 180.

Conclusions
The available evidence demonstrates that the usage of WCD is not affecting PRO, like QoL, depressive symptoms or anxiety negatively.
Nest density ofAtta sexdens(Linnaeus, 1758) in Atlantic Forest restoration sites depends on the surrounding landscape

Published: January 2023

AbstractHerbivory is an important ecological filter, affecting plant establishment in restoration sites. One group of herbivores whose abundance has been increasing with environmental changes are the leaf-cutting ants (LCA). Here we evaluated the influence of the surrounding landscape onAtta sexdensnest density in restoration sites, by testing the hypothesis that sites farthest from forest fragments or with less surrounding habitat cover have higher nest density. The study was conducted in eleven reforestations with native species, amidst an agricultural matrix in southern Brazil. For each site, we estimated LCA nest density (active, inactive and total) and landscape metrics (distance to nearest forest fragment, surrounding habitat area and an index combining both distance and surrounding habitat area, the Proximity Index). There were negative relationships between active and total nest density and surrounding habitat area. These results suggest that increased isolation from forest fragments is a factor contributing to the relaxation of top-down control. Therefore, the increase inA. sexdenspopulation density in restoration sites is a result, at least in part, of low pressure from natural enemies, since LCA are not limited by resource availability.
Assessment of paediatric exertional or peri-exertional syncope: does the story matter?

Published: January 2023

AbstractExertional syncope has been suggested to correlate with a cardiac aetiology, particularly when occurring in mid-stride. The aim of the study is to evaluate the incidence of cardiac disease among children presenting with exertional syncope, determine the influence of timing within activity, and determine the utility of genetic testing and implantable event monitors in the evaluation of cardiac syncope. The patients ≤18 years old with exertional syncope who underwent exercise stress testing between 2008 and 2019 were retrospectively included. Patients were assessed to be in one of three groups: mid-exertion (mid-stride syncope), peri-exertion (syncope during activity but not moving), and post-exertion (within minutes of the activity). A total of 334 patients were included; 46 % were mid-exertion, 18 % were peri-exertion, and 36 % were post-exertion. Thirteen patients (3.8 %) were diagnosed with cardiac syncope; n = 9 (69 %) mid-exertion. Only mid-exertional syncope was significantly associated with a cardiac diagnosis (OR: 2.6). Cardiac diagnoses included inherited arrhythmia syndromes (n = 9), abnormal coronary origins (n = 2), and supraventricular tachycardia (n = 2). Only catecholaminergic polymorphic ventricular tachycardia (n = 5) was associated with mid-exertional syncope (OR: 1.4). The definitive diagnostic test was exercise testing (n = 8), echocardiogram (n = 2), genetic testing (n = 1), ambulatory monitor (n = 1), and EKG (n = 1). Mid-stride syncope was more likely to result in a cardiac diagnosis, and exercise testing is the most common definitive test as catecholaminergic polymorphic ventricular tachycardia was the primary aetiology of exertional syncope in our cohort. Implantable event monitors and genetic testing could be helpful in ruling out cardiac disease.

AbstractBackground:Previous studies have demonstrated the use of virtual reality (VR) in mass-casualty incident (MCI) simulation; however, it is uncertain if VR simulations can be a substitute for in-person disaster training. Demonstrating that VR MCI scenarios can elicit the same desired stress response achieved in live-action exercises is a first step in showing non-inferiority. The primary objective of this study was to measure changes in sympathetic nervous system (SNS) response via a decrease in heart rate variability (HRV) in subjects participating in a VR MCI scenario.Methods:An MCI simulation was filmed with a 360º camera and shown to participants on a VR headset while simultaneously recording electrocardiography (EKG) and HRV activity. Baseline HRV was measured during a calm VR scenario immediately prior to exposure to the MCI scenarios, and SNS activation was captured as a decrease in HRV compared to baseline. Cognitive stress was measured using a validated questionnaire. Wilcoxon matched pairs signed rank analysis, Welch’s t-test, and multivariate logistic regression were performed with statistical significance established at P <.05.Results:Thirty-five subjects were enrolled: eight attending physicians (two surgeons, six Emergency Medicine [EM] specialists); 13 residents (five Surgery, eight EM); and 14 medical students (six pre-clinical, eight clinical-year students). Sympathetic nervous system activation was observed in all groups during the MCI compared to baseline (P <.0001) and occurred independent of age, sex, years of experience, or prior MCI response experience. Overall, 23/35 subjects (65.7%) reported increased cognitive stress in the MCI (11/14 medical students, 9/13 residents, and 3/8 attendings). Resident and attending physicians had higher odds of discordance between SNS activation and cognitive stress compared to medical students (OR = 8.297; 95% CI, 1.408-64.60; P = .030).Conclusions:Live-actor VR MCI simulation elicited a strong sympathetic response across all groups. Thus, VR MCI training has the potential to guide acquisition of confidence in disaster response.

Published: January 2023

AbstractBackground:Treatment resistance in patients with anxiety disorders and obsessive-compulsive disorder (OCD) might be caused by dysfunctional personality traits or, more specifically, early maladaptive schemas (EMSs) and schema modes, that can be treated with schema therapy (ST).Aim:To explore possible effectiveness of ST-CBT day-treatment in patients with treatment-resistant anxiety disorders and OCD in an uncontrolled pilot study.Method:Treatment-resistant patients with anxiety disorders or OCD (n = 27) were treated with ST-CBT day-treatment for 37 weeks on average including 11.5 therapy hours per week. The Symptom Questionnaire-48, Young Schema Questionnaire-2 and Schema Mode Inventory were completed before and after treatment.Results:General psychopathology, EMSs and schema modes significantly improved after treatment. Spearman’s correlations between pre- to post-treatment difference scores of general psychopathology, EMSs and schema modes were significant and high. The level of pre-treatment EMSs and schema modes did not predict post-treatment general psychopathology.Conclusions:Symptom reduction was strongly correlated with improvement of EMSs and schema modes. Stronger pre-treatment EMSs and schema modes did not hinder improvement of symptoms. ST-CBT day-treatment is promising for patients with treatment-resistant anxiety disorders and OCD. Further controlled research is needed to substantiate evidence for schema therapy in patients with treatment-resistant anxiety disorders and OCD.
The relationship between moral distress, individual and professional values in oncology nurses: A structural equation study
Authors: Atli Özbaş Azize , Kovanci Mustafa Sabri , Yilmaz Sakine 
Published: January 2023

AbstractObjectivesThis study examined the relationship between moral distress, individual and professional values in oncology nurses.MethodsEmploying structural equation modeling, a descriptive-correlational study was conducted among 116 oncology nurses. Data were collected using the Moral Distress Scale-Revised Adult Nurses, the Nursing Professional Values Scale, and the Values Scale.ResultsThe mean moral distress frequency was evaluated as low (1.6 ± 0.7) and the intensity as moderate (1.9 ± 0.8). Both the Nursing Professional Values Scale and Values Scale subdimension mean scores were at levels evaluated as high. There was no specific value that stood out from the others. Structural equation modeling analysis showed that individual values were found to have a direct and negative significant effect on moral distress intensity (β = −0.70,p < 0.01) and frequency (β = −0.58,p <0.01) and professional values had a direct positive and significant effect on moral distress intensity (β = 0.37,p < 0.05) and frequency (β = 0.25,p < 0.05).Significance of resultsIt is believed that more national and international studies need to be conducted to examine the relationship between the moral distress concept and values. While individual values were found to have a direct and negative significant effect on moral distress, professional values had a direct positive and significant effect on moral distress.
Rule of law as a determinant of the export performance of Italian provinces
Authors: D'Ingiullo Dario , Di Berardino Claudio , Odoardi Iacopo , Quaglione Davide 
Published: January 2023

AbstractOur article presents an empirical investigation of the relationship between the export performance of Italian provinces and the quality of their local institutions, specifically the rule of law, over the period 2004–2016. According to the results obtained by different econometric approaches (OLS, FE, SYS-GMM), in general a secure and well-defined legal framework – by reducing transaction costs and uncertainty, facilitating capital accumulation and an increase in the firms' scale of production – is associated with better export performance. Interestingly, when the analysis is replicated at the level of the Italian macro-areas (North, Centre and South), the results indicate that the rule of law has a statistically significant and positive association with export performance only in northern provinces, thus suggesting that the effectiveness of this institutional dimension might depend on the level of development of the socioeconomic and institutional features at the local level, i.e. only when a set of suitable economic incentive mechanisms are already in place.
Frontier academic research in OECD countries: the role of institutional factors
Authors: Le Thanh , Vu Bich Ngoc , Mai Sau 
Published: January 2023

AbstractThis paper examines the effect of frontier academic research on technological development and the way institutional quality influences this impact. Using a dataset that covers 18 OECD countries over the 2003–2017 period, we find that frontier academic research exerts an important influence on total factor productivity. First, frontier academic research induces technological change by directly enhancing production processes and management methods. Second, frontier academic research stimulates industrial innovations, which in turn improves productivity. Regarding the moderating effect of institutional variables on these relationships, we find that positive moderation only exists for some, not all, of the institutional variables. In that case, a higher level of these variables is found to strengthen the way countries reap benefits from frontier academic research and industrial innovation. However, the moderation of institutions is much less clear with the process that turns frontier academic research into industrial innovations.
