ABSTRACT
The Hunting Outbursting Young Stars (HOYS) project performs long-term, optical, multifilter, high cadence monitoring of 25 nearby young clusters and star-forming regions. Utilizing Gaia DR3 data, we have identified about 17 000 potential young stellar members in 45 coherent astrometric groups in these fields. Twenty one of them are clear young groups or clusters of stars within 1 kpc and they contain 9143 Gaia selected potential members. The cluster distances, proper motions, and membership numbers are determined. We analyse long-term (≈ 7 yr) V-, R-, and I-band light curves from HOYS for 1687 of the potential cluster members. One quarter of the stars are variable in all three optical filters, and two-thirds of these have light curves that are symmetric around the mean. Light curves affected by obscuration from circumstellar materials are more common than those affected by accretion bursts, by a factor of 2–4. The variability fraction in the clusters ranges from 10 per cent to almost 100 per cent, and correlates positively with the fraction of stars with detectable inner discs, indicating that a lot of variability is driven by the disc. About one in six variables shows detectable periodicity, mostly caused by magnetic spots. Two-thirds of the periodic variables with disc excess emission are slow rotators, and amongst the stars without disc excess two-thirds are fast rotators – in agreement with rotation being slowed down by the presence of a disc.
2.5-MHD models of circumstellar discs around FS CMa post-mergers: II. Stationary accretion stage

ABSTRACT
We study the star–disc interaction in the presence of the strong magnetic field (B⋆ = 6.2 kG) of a slowly rotating star. This situation describes a post-merger of the spectral type B and has not been previously investigated. We perform a set of resistive and viscosity 2.5D-magnetohydrodynamical simulations using the PLUTO code. Based on our previous work, we consider the initial gas disc density ρd0 = 10−13 g cm−3 since it describes the conditions around IRAS 17449+2320 well. We find that the fall of gas towards the star occurs in the mid-plane, and remarkably, intermittent backflow takes place in the mid-plane in all of our models for R ≥ 10R⋆. However, we do not rule out that the funnel effect may occur and cause the accretion closer to the poles. Also, when larger values of viscosity (αν = 1) and stellar rotation rate (δ⋆ = 0.2) are considered, we find that the disc exhibits a thickening which is characteristic of FS CMa-type stellar objects. Additionally, we find that the poloidal magnetic field lines twist over short periods of time, leading to magnetic reconnection causing coronal heating that could explain the presence of the Raman lines found observationally in several FS CMa stars. Lastly, we find the formation of several knots in the magnetic field lines near and in the mid-plane of the disc which produce perturbations in the density and velocity components, as well as the formation of shallow gaps whose position depends on the inflation of the magnetic field lines.

ABSTRACT
In this paper, we use photometric data from the Southern Photometric Local Universe Survey Data Release 4 survey to identify isolated galaxy pairs and analyse their characteristics and properties. Our results align with previous spectroscopic studies, particularly in luminosity function parameters, suggesting a consistent trait among galaxy systems. Our findings reveal a high fraction of red galaxies across all samples, irrespective of projected distance, velocity difference, or luminosity ratio. We found that the proximity of a neighbour to its central galaxy influences its colour due to environmental effects. We also found that central and neighbour have different behaviours: central galaxies maintain a stable red colour regardless of luminosity, while neighbour colours vary based on luminosity ratios. When the central is significantly brighter, the neighbour tends to be less red. According to our division in red, blue, and mixed pairs, we found evidence of galactic conformity. The red pair fractions increase in closer pairs and in pairs of similar luminosity, indicating shared environments promoting red galaxy formation. Analysing local density, the expected colour–density relation is of course recovered, but it is strongly determined by the stellar mass of the pair. In denser environments, the red pair fractions increase, blue pairs decrease, and for the mixed pairs it depends on their stellar mass: more massive mixed pairs decrease their fraction, whereas the less massive ones increase it. These results shed light on the intricate relationship between galaxy pairs, their characteristics, and environmental influences on colour, providing insights into their evolutionary histories.
Density functional theory of material design: fundamentals and applications—II
Authors: Kumar Ashish , Singh Prashant , Harbola Manoj K 
Published: February 2024

Abstract
This is the second and the final part of the review on density functional theory (DFT), referred to as DFT-II. In the first review, DFT-I, we have discussed wavefunction-based methods, their complexity, and basics of density functional theory. In DFT-II, we focus on fundamentals of DFT and their implications for the betterment of the theory. We start our presentation with the exact DFT results followed by the concept of exchange-correlation (xc) or Fermi-Coulomb hole and its relationship with xc energy functional. We also provide the exact conditions for the xc-hole, xc-energy and xc-potential along with their physical interpretation. Next, we describe the extension of DFT for non-integer number of electrons, the piecewise linearity of total energy and discontinuity of chemical potential at integer particle numbers, and derivative discontinuity of the xc potential, which has consequences on fundamental gap of solids. After that, we present how one obtains more accurate xc energy functionals by going beyond the LDA. We discuss the gradient expansion approximation (GEA), generalized gradient approximation (GGA), and hybrid functional approaches to designing better xc energy functionals that give accurate total energies. However, these functionals fail to predict properties like the ionization potential and the band gap. Thus, we next describe different methods of modelling these potentials and results of their application for calculation of the band gaps of different solids to highlight accuracy of different xc potentials. Finally, we conclude with a glimpse on orbital-free density functional theory and the machine learning approach.
The plant cell wall—dynamic, strong, and adaptable—is a natural shapeshifter

Published: February 2024

Abstract
Mythology is replete with good and evil shapeshifters, who, by definition, display great adaptability and assume many different forms—with several even turning themselves into trees. Cell walls certainly fit this definition as they can undergo subtle or dramatic changes in structure, assume many shapes, and perform many functions. In this review, we cover the evolution of knowledge of the structures, biosynthesis, and functions of the 5 major cell wall polymer types that range from deceptively simple to fiendishly complex. Along the way, we recognize some of the colorful historical figures who shaped cell wall research over the past 100 years. The shapeshifter analogy emerges more clearly as we examine the evolving proposals for how cell walls are constructed to allow growth while remaining strong, the complex signaling involved in maintaining cell wall integrity and defense against disease, and the ways cell walls adapt as they progress from birth, through growth to maturation, and in the end, often function long after cell death. We predict the next century of progress will include deciphering cell type–specific wall polymers; regulation at all levels of polymer production, crosslinks, and architecture; and how walls respond to developmental and environmental signals to drive plant success in diverse environments.
Information and Bargaining through Agents: Experimental Evidence from Mexico’s Labour Courts

Published: February 2024

Abstract
Well-functioning courts are essential for the health of both financial and real economies. Courts function poorly in most lower-income countries, but the root causes of poor performance are not well understood. We use field experiments with ongoing cases to analyse sources of dysfunction in Mexico’s largest labour court. We provide parties with personalized predictions for case outcomes and show that this information nearly doubles settlement rates and reduces average case duration. The experiment generates the first experimental evidence in live court cases that reducing information asymmetries results in a decrease in delay, an outcome predicted by many theories of bargaining. We also find that the information treatment is effective only when the plaintiff is present to receive it directly, suggesting agency issues between plaintiffs and their private lawyers. For most workers, the treatment appears to improve welfare, as measured by discounted payouts and ability to pay bills.

Published: February 2024

Abstract

Study Objectives
The study aimed to characterize insomnia symptom trajectories over 12 months during a time of stress and uncertainty, the coronavirus disease 2019 (COVID-19) pandemic. It also aimed to investigate sleep and psychological predictors of persistent insomnia symptoms.

Methods
This longitudinal cohort study comprised 2069 participants with and without insomnia symptoms during the first year of the pandemic. Participants completed online surveys investigating sleep, insomnia, and mental health at four timepoints over 12 months (April 2020–May 2021). Additional trait-level cognitive/psychological questionnaires were administered at 3 months only.

Results
Six distinct classes of insomnia symptoms emerged: (1) severe persistent insomnia symptoms (21.65%), (2) moderate persistent insomnia symptoms (32.62%), (3) persistent good sleep (32.82%), (4) severe insomnia symptoms at baseline but remitting over time (2.27%), (5) moderate insomnia symptoms at baseline but remitting over time (7.78%), and (6) good sleep at baseline but deteriorating into insomnia symptoms over time (2.85%). Persistent insomnia trajectories were predicted by high levels of sleep reactivity, sleep effort, pre-sleep cognitive arousal, and depressive symptoms at baseline. A combination of high sleep reactivity and sleep effort reduced the odds of insomnia remitting. Higher sleep reactivity also predicted the deterioration of good sleep into insomnia symptoms over 12 months. Lastly, intolerance of uncertainty emerged as the only trait-level cognitive/psychological predictor of insomnia trajectory classes.

Conclusions
Insomnia was more likely to persist than remit over the first year of the COVID-19 pandemic. Addressing sleep reactivity and sleep effort appears critical for reducing insomnia persistence rates after times of stress and uncertainty.
Mesenchymal Stromal/Stem Cells Know Best: The Remarkable Complexities of Its Interactions With Polymorphonuclear Neutrophils

Published: February 2024

Abstract
Polymorphonuclear neutrophils (PMNs), the predominant immune cell type in humans, have long been known as first-line effector cells against bacterial infections mainly through phagocytosis and production of reactive oxygen species (ROS). However, recent research has unveiled novel and pivotal roles of these abundant but short-lived granulocytes in health and disease. Human mesenchymal stromal/stem cells (MSCs), renowned for their regenerative properties and modulation of T lymphocytes from effector to regulatory phenotypes, exhibit complex and context-dependent interactions with PMNs. Regardless of species or source, MSCs strongly abrogate PMN apoptosis, a critical determinant of PMN function, except if PMNs are highly stimulated. MSCs also have the capacity to fine-tune PMN activation, particularly in terms of CD11b expression and phagocytosis. Moreover, MSCs can modulate numerous other PMN functions, spanning migration, ROS production, and neutrophil extracellular trap (NET) formation/NETosis, but directionality is remarkably dependent on the underlying context: in normal nondiseased conditions, MSCs enhance PMN migration and ROS production, whereas in inflammatory conditions, MSCs reduce both these functions and NETosis. Furthermore, the state of the MSCs themselves, whether isolated from diseased or healthy donors, and the specific secreted products and molecules, can impact interactions with PMNs; while healthy MSCs prevent PMN infiltration and NETosis, MSCs isolated from patients with cancer promote these functions. This comprehensive analysis highlights the intricate interplay between PMNs and MSCs and its profound relevance in healthy and pathological conditions, shedding light on how to best strategize the use of MSCs in the expanding list of diseases with PMN involvement.

Published: February 2024

Background:
The demand for soft tissue filler injections has experienced a significant increase in recent years. Therefore, this study used bibliometric analysis to identify prominent research areas and emerging trends within the field.

Methods:
Publications concerning research on soft tissue filler injections were collected from the Web of Science Core Collection database. Subsequently, VOSviewer 1.6.18 and CiteSpace 6.2.R4 software were used to analyze the co-authorship, co-occurrence, and citations of countries, institutions, authors, hotspot keywords, and journals associated with these studies.

Results:
A total of 1370 records pertaining to filler injection research conducted between 2000 and 2022 were identified. The United States (524 publications) emerged as the country with the highest number of publications in this field, with Mayo Clinic (37 publications) making the most substantial contribution. Dermatologic Surgery emerged as the leading journal in this field, publishing the highest number of research articles (151 publications) and also being the most frequently co-cited. Cotofana proved to be the most prolific author with 51 publications, and Lemperle emerged as the most frequently co-cited author with 628 citations (including total link strength: 6587). The most popular keywords, in descending order of popularity, were “dermal filler,” “injection,” “soft-tissue augmentation,” “complications,” and “hyaluronic acid.”

Conclusions:
The findings of this study offer a comprehensive overview of the main directions in filler injection research. Furthermore, they underscore the imperative of intensifying efforts to prevent complications linked to filler injections.
Simulating mitral repair: lessons learned
Authors: White Abigail , Zarzycki Anna , Bisleri Gianluigi 
Published: February 2024

Purpose of review
With the growing complexity of cardiac surgical cases, increased focus on patient safety, and minimally invasive techniques, simulation-based training has experienced a renaissance. This review highlights important elements of simulation-based training, focusing specifically on available simulators for mitral valve repair and the uses for simulation.

Recent findings
Referring to simulators as being high or low fidelity is oversimplified. Fidelity is a multifactorial concept, and for surgical task trainers, structural and functional fidelity should be discussed. For mitral valve repair, there are a spectrum of simulators, including tissue-based models, bench-top models, and hybrid models. All these simulator modalities serve a role in training if they align with predetermined objectives. There have been advancements in mitral valve repair simulation, notably patient-specific 3D printed silicone replicas of disease.

Summary
There is evidence to support that simulation improves performance in the simulated environment, but future investigation should look to determine whether simulation improves performance in the clinical setting and ultimately patient outcomes.

Published: February 2024

Purpose:
The aim of this study was to report long-term outcomes of patients who have undergone Boston type I keratoprosthesis (KPro) surgery.

Methods:
This study was a retrospective review. Inclusion criteria were KPro surgery between 2006 and 2012 and at least 10 years of follow-up. Demographics, ocular history, surgery indication, clinical variables, and postsurgical outcomes were recorded. Descriptive statistical analysis was performed.

Results:
We identified 75 patients with KPro implantation, and 17 patients with at least 10 years of follow-up (median = 11.1 years; range, 10.0–12.8 years) were included. Of 17 eyes, 11 (64.8%) had their original device in situ, 3 (17.6%) had their second device in situ, 1 (5.9%) had the device removed and replaced with a donor keratoplasty, and 2 (11.8%) were enucleated. At the last follow-up, 11 eyes (64.7%) were able to maintain improvement in vision, 5 (29.4%) had worsened vision, 1 (5.9%) had stable vision, and 9 (52.9%) had visual acuity <Snellen 20/200. Major complications included infectious keratitis (n = 5, 29.4%), hypotony (n = 4, 23.5%), retinal detachment (n = 4, 23.5%), endophthalmitis (n = 2, 11.8%), and retroprosthetic membrane (n = 7, 50%). In addition, 15 eyes (88.2%) required glaucoma surgery. All but 1 eye lost best-ever visual acuity with 9 eyes (52.9%) because of glaucoma progression.

Conclusions:
KPro had an acceptable retention proportion and remains a viable option for eyes at high risk of failure with donor keratoplasty. However, subsequent surgeries are commonly performed postoperatively to manage complications. Glaucoma seems to be the main etiology of irreversible vision loss.
Falsely prolonged prothrombin time test in a patient with erythrocytosis: a case report

Published: February 2024

The prothrombin time (PT) test is commonly used to monitor deficiencies in coagulation factors. A prolonged PT may indicate a deficiency of factors II, V, VII, X, and fibrinogen, or the presence of an inhibitor. However, further tests are required to differentiate between a true factor deficiency and the presence of an inhibitor. It is important to note that falsely prolonged PT can lead to misdiagnosis and inappropriate clinical intervention that can have life-threatening consequences.
A 19-year-old woman with elevated hematocrit levels and prolonged PT was diagnosed with secondary erythrocytosis due to cyanotic congenital heart disease with ventricular septal defect (VSD). However, further investigation revealed that the prolonged PT result was false. Excess citrate in the blood sample, caused by polycythemia, led to this misleading outcome, resulting in unnecessary and potentially harmful treatment.
This incident emphasizes the importance of laboratory personnel and clinicians being aware of the test's limitations. Not only should specialists in thrombosis and hemostasis possess this knowledge, but it is also pertinent for general laboratory staff, as well as laboratory directors and specialists. The significance of accurate laboratory testing for the proper diagnosis and treatment of patients is highlighted in this case.

Published: February 2024

Introduction:
To investigate the clinical features, pregnancy care, timing, and approaches of pregnancy termination as well as the perinatal management of pregnant women with ectopic pheochromocytomas (EPCC) (paragangliomas, PGL).

Methods:
We report the diagnosis and treatment of a pregnant women with EPCC which was confirmed in the third trimester in our hospital. Literature in relation to EPCC during pregnancy both in and outside China was searched for data analysis such as maternal clinical features and maternal and fetal prognosis.

Results:
A total of 20 papers including 21 cases (plus ours) were retrieved. The average age of pregnant patients was 28 years old (from 21 to 37). Two patients presented no hypertension. Nineteen had hypertension in various extent with the accompany of headache (11 cases, 57.9%), palpitations (8 cases, 42.1%), sweating (6 cases, 31.6%), nausea (6 cases), abdominal pain (2 cases), etc. The tumor was found in the chest in 3 patients, in the upper abdomen in 1 patient, in the middle abdomen in 10 patients, between the lower abdomen and pelvic cavity in 3 patients and in the pelvic cavity in 3 patients. Five patients had a surgical removal of the tumor before delivery, 3 during cesarean section and 10 after giving birth.

Conclusion:
EPCC (PGL) during pregnancy is a rare extra-adrenal tumor, whose manifestations are often confused with those of pregnancy-induced hypertension. It is extremely hard to diagnosis the disease before surgery. Patients still have an opportunity of undergoing spontaneous delivery if their tumors have been removed before labor. However, for patients whose pheochromocytomas is localized before labor, it is better to terminate their pregnancy via cesarean section in a proper time according to their obstetric conditions, while under the supervision of multidisciplinary specialists. The preparations of both α and β adrenergic receptor blocker treatment that is normally carried out before PGL removal surgery are unnecessary to be overemphasized before the cesarean section.
