Published: February 2024

AbstractBackgroundSocially marginalised patients face many challenges related to their health condition and often have several contacts with healthcare and social service workers. The Danish social nursing initiative, whose nurses have experience and knowledge about marginalisation, aims to support socially marginalised patients during hospital admission and through hospital transitions. However, there is limited knowledge about the hospital transitions of patients being supported by a social nurse.ObjectivesThe objectives of this study were to explore (1) the perspectives of socially marginalised patients on the transition from hospital to home and (2) how these patients experience the importance of social nursing on patient trajectories after hospital discharge.MethodsA qualitative study with a phenomenological and hermeneutic approach was performed at a large hospital in southern Denmark. Adult patients who had contact with a social nurse during hospital admission were purposely sampled. Data were collected between January 2023 and March 2023. Initial patient interviews were conducted during hospital admission with a second interview 7–22 days after discharge. Systematic text condensation was used for the analysis, and Nvivo 12 supported data storage and coding.Ethical ApprovalThe study is registered with the Danish Data Protection Agency (22/47509). Informed consent was given by the participants.ResultsSixteen patients participated in the study. The participants experienced major challenges in their transitions from the hospital, which were generally related to their interactions with many different social and healthcare services. While the social nurses supported the patients and helped facilitate care during hospital admission and after discharge, the participants identified transitional care gaps related to multidisciplinary cooperation and standardised care options.ConclusionsThis study identifies challenges related to the hospital transition of socially marginalised patients, which indicates a gap in healthcare services. Future research should focus on improving interprofessional collaboration with socially marginalised patients across healthcare services.
‘Our Voices Aren't Being Heard’: A qualitative descriptive study of nurses' perceptions of interprofessional collaboration in care supporting older people's functioning during a hospital stay
Authors: Butler Jeffrey I. , Fox Mary T. 
Published: February 2024

AbstractIntroductionOlder people admitted to hospital are highly susceptible to functional decline and related complications. Care supporting their functioning is complex and requires healthcare professionals working in concert, with nurses playing a central role. Yet, little is known about nurses' perceptions of interprofessional collaboration (IPC) in care supporting functioning in acutely admitted older people. To fill this knowledge gap, we elucidate the perspectives of nurses in Ontario, Canada, on IPC in care supporting older people's functioning during a hospital stay.MethodsWe employed a qualitative methodology in conjunction with a qualitative descriptive design. Thirteen focus groups were held with a purposeful, criterion‐based sample of 57 acute care nurses practising in a range of acute care settings (e.g. Emergency, General Medicine, General Surgery, Intensive Care, Coronary Care). Data were thematically analysed.ResultsWe identified two overarching themes: (1) IPC is improving, but nurses are excluded from decision‐making and (2) nurse advocacy causes friction with other professionals. The first theme captures nurses' perception that IPC in older people's care is improving, but nurses are marginalised in interprofessional decision‐making. As a result, nurses perceive that their knowledge is devalued, and their contributions to care supporting older people's functioning are undermined. The second theme underlines a tension between interprofessional team practices and patient‐ and family‐centred care, while also demonstrating nurses' increasing willingness to act as patient and family advocates.ConclusionsFindings can be used to enhance IPC in care supporting the functioning of acutely hospitalised older people. To improve IPC, clinical and administrative leaders should cultivate more egalitarian team relationships that encourage nurses to contribute to decision‐making and advocate on behalf of older patients and their families.

AbstractIntroductionIt is common practice for researchers to monitor responses to items assessing suicidal ideation and follow‐up with high‐risk participants, when their identities are known. However, it is becoming increasingly common for researchers to administer fully anonymous online surveys that do not allow for follow‐ups with participants at higher risk. The aim of the current study was to investigate whether these two different approaches—monitoring and follow‐up versus no monitoring or follow‐up—affect the willingness of participants to endorse suicidal ideation.MethodsThe sample included N = 555 undergraduate students, who were randomly assigned to the monitoring (n = 275) or anonymous (n = 280) instruction conditions, with the monitoring condition shifting to anonymous, non‐monitored responses at Time 2.ResultsThere were no significant differences in self‐reported suicidal ideation between those in the monitoring and anonymous condition at Time 1. At Time 2, no significant interaction was identified between condition and time, suggesting that the change in instructions across timepoints for the monitoring condition had no impact on endorsement of suicidal ideation.ConclusionFindings indicate that both monitoring and anonymous instruction methods should elicit the same pattern of endorsements of suicidal ideation.

AbstractPurposeStudies of medical students suggest they often find the transition from the pre‐clinical curriculum to clinical rotations particularly challenging during perioperative clerkships. Educators could add a new perspective into students' clerkship experiences and potential interventions to improve them. The purpose of this study was to examine the educator perspective on students' experiences in perioperative clerkships. The findings could inform potential curricular interventions to facilitate student transition from a didactic environment into perioperative clerkships.MethodsSemi‐structured qualitative interviews were conducted with 16 faculty and residents in the departments of anaesthesia, obstetrics and gynaecology (OBGYN), and general surgery across multiple clinical teaching sites at one institution. Interview questions explored their perceptions of the challenges students face during their transition into perioperative clerkships and probed thoughts on curriculum interventions they believed would be the most beneficial. Interviews were recorded, transcribed and analysed thematically.FindingsThree themes were identified. Faculty and residents perceive that student experiences on perioperative clerkships are shaped by (1) students' ability to adapt to the specialty and operating room norms on these clerkships, (2) students' understanding of how they can meaningfully contribute to the clinical team, and (3) dedicated teaching time constraints. Interventions were suggested to address educator expectations and student gaps, such as implementing a pre‐clerkship orientation across anaesthesia, general surgery and OBGYN.ConclusionsTo facilitate the medical student transition to perioperative clerkships, interventions should aid students in adapting to clerkship norms for these specialties and clarifying their role and expectations within the care team.

AbstractThe late Miocene Monte Capanne and Porto Azzurro plutons are investigated by means of coupled U–Pb zircon and 40Ar/39Ar white mica dating to test the occurrence of long‐lived magmatic systems in the upper crust. Zircon crystallized for >1 Ma in both plutonic systems, with supersolidus conditions overlapping for ~220 ka indicating previously unrecognized co‐existence of the two reservoirs. The development of the Porto Azzurro high T‐aureole is post‐dated by continuous igneous zircon crystallization until ~6.0 Ma. By linking crystallization to post‐emplacement cooling of late‐stage pulses in both western and eastern Elba we constrain long‐lived sizeable reservoirs (possibly the same reservoir) in the Tyrrhenian upper crust between ~8 and 6 Ma.

SUMMARYPlants growing under natural conditions experience high light (HL) intensities that are often accompanied by elevated temperatures. These conditions could affect photosynthesis, reduce yield, and negatively impact agricultural productivity. The combination of different abiotic challenges creates a new type of stress for plants by generating complex environmental conditions that often exceed the impact of their individual parts. Transcription factors (TFs) play a key role in integrating the different molecular signals generated by multiple stress conditions, orchestrating the acclimation response of plants to stress. In this study, we show that the TF WRKY48 negatively controls the acclimation of Arabidopsis thaliana plants to a combination of HL and heat stress (HL + HS), and its expression is attenuated by jasmonic acid under HL + HS conditions. Using comparative physiological and transcriptomic analyses between wild‐type and wrky48 mutants, we further demonstrate that under control conditions, WRKY48 represses the expression of a set of transcripts that are specifically required for the acclimation of plants to HL + HS, hence its suppression during the HL + HS stress combination contributes to plant survival under these conditions. Accordingly, mutants that lack WRKY48 are more resistant to HL + HS, and transgenic plants that overexpress WRKY48 are more sensitive to it. Taken together, our findings reveal that WRKY48 is a negative regulator of the transcriptomic response of Arabidopsis to HL + HS and provide new insights into the complex regulatory networks of plant acclimation to stress combination.
Marginal resection and infracyanine green‐mediated photodynamic therapy in the management of feline eyelid squamous cell carcinoma: Two cases
Authors: Sebbag Lionel , Pe'er Oren 
Published: February 2024

AbstractObjectiveDescribe the presenting features, surgical procedure, and clinical outcomes of two cats managed with marginal resection and photodynamic therapy (PDT) for eyelid squamous cell carcinoma (SCC).Animals StudiedA 12‐year‐old female spayed domestic shorthair cat (case 1) and a 10‐year‐old female spayed domestic shorthair cat (case 2).ProceduresFollowing marginal resection of the eyelid neoplasm, hemostasis was achieved using a handheld cautery unit then 1 mL of infracyanine green was injected into the surgical wound bed. Photodynamic therapy was performed using an 810 nm diode laser in two consecutive steps: (i) six cycles at 500 mW for 30 s per cycle, using a rapid movement; then (ii) one (case 1) or two cycles (case 2) of 30 s at 2000 mW, using a slow deliberate movement to effect (charred surface).ResultsHistopathology was consistent with SCC resected with incomplete margins in both cats. Follow‐up duration was 416 and 161 days in case 1 and case 2, respectively. Consecutive exams and photo‐documentation (in clinic or by owners) showed appropriate healing of the lower eyelid, with a smooth lid margin, and no evidence of tumor regrowth or ocular irritation. Subtle trichiasis was noted in case 1 on day 185, but not at the last follow‐up.Conclusions and Clinical RelevanceMarginal resection followed by PDT may be a valid alternative to complete surgical resection of periocular SCC in cats. The procedure was easy to perform, post‐operative recovery was uncomplicated, and neither cat developed recurrent disease during the follow‐up period.

AbstractThe accurate diagnosis of portovascular anomalies has been facilitated by improvements in diagnostic imaging technology. In humans, hepatic arterial blood flow changes in response to the reduction in portal blood flow. The hepatic arterial buffer response characterizes an intrinsic regulatory mechanism in response to reduced portal venous blood flow, which results in hepatic arterial enlargement. At the authors’ institution, enlargement of the hepatic artery has been anecdotally observed in a population of dogs with extrahepatic portosystemic shunting, consistent with previous literature that documents variability in hepatic arterial size. In this retrospective, blinded, analytical study, a hepatic artery:aorta (Ha:Ao) ratio was assessed on CT studies from 112 dogs, with (n = 43) and without (n = 69) an extrahepatic congenital portosystemic shunt in order to compare the hepatic artery size independent of body weight between the two populations. A significant increase in the Ha:Ao ratio was documented in dogs with an extrahepatic portosystemic shunt (EHPSS) compared with those dogs with no EHPSS independent of the location of shunt insertion into the systemic circulation (P < .001). Three cases had repeat CT after surgery, and all had Ha:Ao ratio reductions following treatment. The authors propose that this may be an additional imaging feature observed in dogs with an EHPSS.

AbstractEnvironmental processes in cities and suburbs are significantly impacted by climate change. The development of reliable ecological models may successfully direct agricultural activities. Numerous models have been put forth as of late; however, because to the complexity of environmental microorganisms, their use in complex systems is still restricted. For a better understanding of the ecological restoration of an urban lake system that had been disturbed by rainfall, an improved ecological dynamic model that took into account inundation plants, phytoplankton and microorganisms was proposed based on the field survey. Observed data from a shallow urban lake with a surface area of approximately 66 600 m2 in the heart of Shunde district, Foshan, in South China, was used to validate the model. In this model, five hypotheses—phytoplankton, microorganisms, NH3‐N, COD and TP in water—were selected as experimental variables. To assess the model's correctness and dependability, the correlation coefficients (R) and root mean square error‐observations standard deviation ratio (RSR) were computed. The results from the establish model (0.446 < R < 0.985, RSR < 0.7) are very similar to those of actual observations. In addition, four microbe species (Aquabacium, Bradyrhizobium japonicum, Curvibacter and Cyanobacteria) multiplied when pollutant concentration dropped. Our model provides a useful tool for managing urban shallow water lakes by properly simulating the dynamic changes of aquatic species and microbes in urban shallow water lakes.

AbstractThe Prionospio complex comprises the most diverse and complex group within the polychaete family Spionidae. The phylogenetic relationships within the group are still poorly understood, and the generic breakdown is unstable. In this study, we assessed the diversity, relationships, and distribution of species of the Prionospio complex occurring in Norwegian waters. We analysed mitochondrial genomes and nuclear ribosomal DNA assembled via whole‐genome shotgun sequencing, and Sanger sequenced fragments of COI and 16S rDNA. Sanger sequencing proved challenging in the group, where COI was only amplified successfully in 14% of specimens. By molecular species delimitation algorithms, our study revealed the presence of four well‐supported but currently undescribed species of Prionospio in Norwegian waters. We observed a novel distribution pattern of polychaetes in coastal waters, where certain species demonstrated distribution ranges spanning over 7000 km. Such wide distribution parallels patterns of deep‐sea Prionospio species, suggesting that factors beyond recent anthropogenic translocations are involved. Our analysis of 38 mitochondrial genomes and ribosomal nuclear DNA enabled us to hypothesise on the phylogenetic relationships of 14 species of the Prionospio complex. The analysis suggested that two characters previously used to designate genera: the beginning of the branchiae from chaetiger 3 and the presence of pinnules on the branchiae, might have evolved more than one time within the complex. We return Aurospio banyulensis to the genus Prionospio according to the diagnosis of Aurospio resulting tree where this species was nested among Prionospio species. Our findings provide new insights into the diversity and distribution patterns of Prionospio species and contribute to a better understanding of marine benthic biodiversity and the importance of taxonomic accuracy in conservation and management practices.
On the geometry of rod packings in the 3‐torus

Published: February 2024

AbstractRod packings in the 3‐torus encode information of some crystal structures in crystallography. They can be viewed as links in the 3‐torus, and tools from 3‐manifold geometry and topology can be used to study their complements. In this paper, we initiate the use of geometrisation to study such packings. We analyse the geometric structures of the complements of simple rod packings, and find families that are hyperbolic and Seifert fibred.
A Comparative Study of Machine Learning and Algorithmic Approaches to Automatically Identify the Yield Point in Normal and Aneurysmal Human Aortic Tissues

Abstract
The stress–strain curve of biological soft tissues helps characterize their mechanical behavior. The yield point on this curve is when a specimen breaches its elastic range due to irreversible microstructural damage. The yield point is easily found using the offset yield method in traditional engineering materials. However, correctly identifying the yield point in soft tissues can be subjective due to its nonlinear material behavior. The typical method for yield point identification is visual inspection, which is investigator-dependent and does not lend itself to automation of the analysis pipeline. An automated algorithm to identify the yield point objectively assesses soft tissues' biomechanical properties. This study aimed to analyze data from uniaxial extension testing on biological soft tissue specimens and create a machine learning (ML) model to determine a tissue sample's yield point. We present a trained machine learning model from 279 uniaxial extension curves from testing aneurysmal/nonaneurysmal and longitudinal/circumferential oriented tissue specimens that multiple experts labeled through an adjudication process. The ML model showed a median error of 5% in its estimated yield stress compared to the expert picks. The study found that an ML model could accurately identify the yield point (as defined) in various aortic tissues. Future studies will be performed to validate this approach by visually inspecting when damage occurs and adjusting the model using the ML-based approach.

Published: February 2024

The potential scope for qualified sport psychology service providers is broadening. Recent empirical research and associated commentaries have highlighted the opportunity for applied sport psychology professionals to apply concepts and experiences toward having a positive effect on athletes’ training environment. This case study details a high-performance leader within an Australian national training institute who is also a trained sport psychology practitioner, attempting to optimize psychological effects in the time leading up to the Tokyo 2020 (i.e., 2021) Olympic Games. The objective was to meet or exceed medal targets though the provision of a strong, team-led approach where activity to achieve high-performance outcomes was prioritized but in a manner that leveraged strong professional relationships and through the prioritization of everyone’s mental and emotional health whenever practicably achievable.
