Introduction

ABSTRACT Far from simply being a ‘bookend’ of the industrial age, deindustrialization is an integral part of capitalist development and thus has a long history. In the North American context, the early scholarship on deindustrialization emerged from the efforts to resist plant closures as they were happening. More recently, the field of deindustrialization studies has been reinvigorated by authors who have shifted the centre of gravity from the US Rust Belt to Europe and increasingly to other parts of the world. This introduction traces the emergence and recent transformations in the field of deindustrialization studies. It also introduces this themed issue on the politics of deindustrialization, which tells the stories of shuttered mines, mills, and factories within the wider restructuring of the international division of labour in the late twentieth century. The articles, written from a range of disciplinary perspectives, extend outward to how workers, their unions, state actors, and the general public responded to the challenge of deindustrialization. The authors are all affiliated with the ‘Deindustrialization and the Politics of Our Time’ (DePOT) research project (deindustrialization.org), which brings together many of the world’s leading deindustrialization scholars to put the field in transnational perspective. By extending the range of comparisons and scales of analysis, this special-themed issue invites us to broaden our understanding of deindustrialization, both thematically and methodologically.

Outcomes of control and monitoring of a widespread riparian invader (Tamarix spp.): a comparison of synthesis approaches

Effective ecological restoration requires empirical assessment to determine outcomes of projects, but conclusions regarding the effects of restoration treatments on the whole ecosystem remain rare. Control of invasive shrubs and trees in the genus Tamarix and associated riparian restoration in the American Southwest has been of interest to scientists and resource managers for decades; dozens of studies have reported highly variable outcomes of Tamarix control efforts, as measured by a range of response variables, temporal and spatial scales and monitoring strategies. We conducted a literature search and review, meta-analysis and vote count (comparison of numerical outcomes lacking reported variances and/or sample sizes) on published papers that quantitatively measured a variety of responses to control of Tamarix. From 96 publications obtained through a global search on terms related to Tamarix control, we found 52 publications suitable for a meta-analysis (n = 777 comparisons) and 63 publications suitable for two vote counts (n = 1,460 comparisons total; 622 comparisons reported as statistically significant) of response to Tamarix control. We estimated responses to control by treatment type (e.g. cut-stump treatment, burning, biocontrol) and ecosystem component (e.g. vegetation, fauna, fluvial processes). Finally, we compared results of the various synthesis methods to determine whether the increasingly stringent requirements for inclusion led to biased outcomes. Vegetation metrics, especially measures of Tamarix response, were the most commonly assessed. Ecosystem components other than vegetation, such as fauna, soils and hydrogeomorphic dynamics, were under-represented. The meta-analysis showed significantly positive responses by vegetation overall to biocontrol, herbicide and cut-stump treatments. This was primarily due to reduction of Tamarix cover; impacts on replacement vegetation were highly variable. We found concordance amongst our varied synthesis approaches, indicating that increased granularity from stricter quantitative techniques does not come at the cost of a biased sample. Overall, our results indicate that common control methods are generally effective for reducing Tamarix, but the indirect effects on other aspects of the ecosystem are variable and remain understudied. Given that this is a relatively well-studied invasive plant species, our results also illustrate the limitations of not only individual studies, but also of reviews for measuring the impact of invasive species control. We call on researchers to investigate the less commonly studied responses to Tamarix control and riparian restoration including the effects on fauna, soil and hydrogeomorphic characteristics.

A Phase 3 Trial of Seladelpar in Primary Biliary Cholangitis

BackgroundEffective treatments for patients with primary biliary cholangitis are limited. Seladelpar, a peroxisome proliferator–activated receptor delta agonist, has potential benefits.MethodsIn this phase 3, 12-month, double-blind, placebo-controlled trial, we randomly assigned (in a 2:1 ratio) patients who had had an inadequate response to or who had a history of unacceptable side effects with ursodeoxycholic acid to receive oral seladelpar at a dose of 10 mg daily or placebo. The primary end point was a biochemical response, which was defined as an alkaline phosphatase level less than 1.67 times the upper limit of the normal range, with a decrease of 15% or more from baseline, and a normal total bilirubin level at month 12. Key secondary end points were normalization of the alkaline phosphatase level at month 12 and a change in the score on the pruritus numerical rating scale (range, 0 [no itch] to 10 [worst itch imaginable]) from baseline to month 6 among patients with a baseline score of at least 4 (indicating moderate-to-severe pruritus).ResultsOf the 193 patients who underwent randomization and treatment, 93.8% received ursodeoxycholic acid as standard-of-care background therapy. A greater percentage of the patients in the seladelpar group than in the placebo group had a biochemical response (61.7% vs. 20.0%; difference, 41.7 percentage points; 95% confidence interval [CI], 27.7 to 53.4, P<0.001). Normalization of the alkaline phosphatase level also occurred in a greater percentage of patients who received seladelpar than of those who received placebo (25.0% vs. 0%; difference, 25.0 percentage points; 95% CI, 18.3 to 33.2, P<0.001). Seladelpar resulted in a greater reduction in the score on the pruritus numerical rating scale than placebo (least-squares mean change from baseline, −3.2 vs. −1.7; least-squares mean difference, −1.5; 95% CI, −2.5 to −0.5, P=0.005). Adverse events were reported in 86.7% of the patients in the seladelpar group and in 84.6% in the placebo group, and serious adverse events in 7.0% and 6.2%, respectively.ConclusionsIn this trial involving patients with primary biliary cholangitis, the percentage of patients who had a biochemical response and alkaline phosphatase normalization was significantly greater with seladelpar than with placebo. Seladelpar also significantly reduced pruritus among patients who had moderate-to-severe pruritus at baseline. The incidence and severity of adverse events were similar in the two groups.

Consistent detection of Trypanosoma brucei but not T. congolense DNA in faeces of experimentally infected cattle

Animal African trypanosomiasis (AAT) is a significant food security and economic burden in sub-Saharan Africa. Current AAT empirical and immunodiagnostic surveillance tools suffer from poor sensitivity and specificity, with blood sampling requiring animal restraint and trained personnel. Faecal sampling could increase sampling accessibility, scale, and species range. Therefore, this study assessed feasibility of detecting Trypanosoma DNA in the faeces of experimentally-infected cattle. Holstein–Friesian calves were inoculated with Trypanosoma brucei brucei AnTat 1.1 (n = 5) or T. congolense Savannah IL3000 (n = 6) in separate studies. Faecal and blood samples were collected concurrently over 10 weeks and screened using species-specific PCR and qPCR assays. T. brucei DNA was detected in 85% of post-inoculation (PI) faecal samples (n = 114/134) by qPCR and 50% by PCR between 4 and 66 days PI. However, T. congolense DNA was detected in just 3.4% (n = 5/145) of PI faecal samples by qPCR, and none by PCR. These results confirm the ability to consistently detect T. brucei DNA, but not T. congolense DNA, in infected cattle faeces. This disparity may derive from the differences in Trypanosoma species tissue distribution and/or extravasation. Therefore, whilst faeces are a promising substrate to screen for T. brucei infection, blood sampling is required to detect T. congolense in cattle.

Effect of probiotics plus zinc supplementation on clinical outcomes of infants and children with acute infectious diarrhea: a randomized controlled trial.

Findings are conflicting regarding the effect of zinc supplementation on disease severity in children with acute gastroenteritis. To examine the effects of probiotics and zinc on the clinical outcomes of infants and children with acute infectious diarrhea. In this randomized controlled trial, children with mild or moderate to severe acute gastroenteritis in the Kurdistan Region from November 2021 to June 2022 were diagnosed clinically and randomly assigned to the experimental or control group. The experimental group (n=50) received probiotics and zinc, whereas the control group (n=51) received probiotics alone for 1 week. The product contained live Bifidobacterium infantis, Lactobacillus paracasei, and Lactobacillus rhamnosus (10×106 colony-forming units/day for 7 days). Zinc syrup was administered to the probiotic plus zinc group. Each 5 mL of syrup contained 15 mg of zinc sulfate. Dehydration and disease severity in both groups were measured using the Clinical Dehydration Scale and the Modified Vesikari Scale, respectively. An illness episode was defined as an episode of gastroenteritis with a total score of ≥9 on the Modified Vesikari Scale (range, 0-20). The probiotic and probiotic plus zinc groups were similar in age (1.79 years vs. 1.69 years, respectively; P= 0.645), sex (male/female ratio: 1.43 and 1.0, respectively; P=0.373), and medical characteristics. The groups had similar mean dehydration and disease severity scores and a similar incidence of dehydration recovery (some dehydration, 3.92% and 4.00%, respectively; P=1.000), and recovery from mild gastroenteritis (0.0% and 2.0%, respectively; P=0.495) at 2 weeks. Significant decreases in mean dehydration severity and disease severity score (1.80 to 0 and 6.66 to 0, respectively; P<0.001) and the development of dehydration (some dehydration, from 94.0% to 4.0%; P<0.001) from baseline to 2 weeks were noted in the probiotics plus zinc group. The probiotics group responded similarly. The development of mild gastroenteritis was significantly reduced from baseline to 2 weeks (90.2% to 0% and 78.0% to 2.0% in the probiotics and probiotics plus zinc groups, respectively; P<0.0001). The probiotics plus zinc group had a shorter mean recovery time (1.34 days vs. 2.00 days, respectively; P<0.001). Taking probiotics plus zinc did not significantly affect disease severity in children with gastroenteritis at 2 weeks. However, the probiotics plus zinc group recovered more quickly than the probiotics group.

Tracking Molecular Fragmentation in Electron-Ionization Mass Spectrometry with Ultrafast Time Resolution.

ConspectusMass spectrometry is a powerful analytical method capable of identifying compounds given a minute amount of material. The fragmentation pattern that results following molecular activation serves as a fingerprint that can be matched to a database compound for identification. Over the past half century, studies have addressed and, in many cases, named the chemical reactions that lead to some of the principal fragment ions. Theories have been developed to predict the observed fragmentation patterns, many of which assume that energy redistributes prior to dissociation. However, the existence of rearrangements and nonergodic processes complicates the prediction of fragmentation patterns and the identification of compounds that have yet to be entered into a curated database. To date, very few studies have addressed the time-dependent nature of the fragmentation of radical cations and, in particular, processes occurring with picosecond or shorter time scales where one expects to find nonergodic reactions.This Account focuses on a novel approach that enables tracking of molecular fragmentation in electron-ionization mass spectrometry with ultrafast time resolution. The two challenges that have prevented the time-resolved studies following electron ionization are the random impact parameter and moment of ionization of each molecule. In addition, medium-sized molecules can produce fragmentation patterns with tens if not hundreds of product ions. Spectroscopically interrogating all of these ions as a function of time is another major challenge. We describe strong field disruptive probing, a method that ionizes molecules on a femtosecond time scale and allows us to track in time the formation of all fragment ions simultaneously.Molecular fragmentation following ionization can occur on a very wide range of time scales. Metastable ions can survive from nanoseconds to microseconds; reactions that depend on vibrational energy redistribution can take picoseconds to nanoseconds; and direct dissociation processes and some rearrangements can take place in femtoseconds to picoseconds. All of these processes depend on the dynamics that occur during attoseconds and femtoseconds following the ionization process. Following a discussion of these time scales, we provide three examples of fragmentations that have been studied with femtosecond time resolution. Each of these examples include unforeseen reaction dynamics that involve a nonergodic process, highlighting the importance of time resolution in mass spectrometry. Finally, we explore future challenges and unresolved questions in mass spectrometry and, more broadly, in the domain of electron-initiated chemical reactions.

A randomized controlled trial: The efficacy and safety of Bushen Huoxue formula in the management of lower back pain from lumbar disc herniation.

Lower back pain (LBP) arising from lumbar disc herniation (LDH) poses a challenging health issue, often necessitating therapeutic interventions. Bushen Huoxue formula (BSHXF) has proved as a potential treatment option with great clinical effect. However, comprehensive investigations into its efficacy and safety in conjunction with celecoxib for managing LBP from LDH are lacking. The objective of this article is to investigate the efficacy and safety of BSHXF in the management of patients with LBP from LDH. This single center, randomized clinical trial was conducted from March 2023 to September 2023 and all patients suffered from LBP of LDH. Participants were randomly assigned to the BSHXF group (celecoxib and BSHXF) or the control group (celecoxib and placebo). The patients received treatment for 2 weeks. Assessment was conducted before treatment, the last day of the treatment, 4 weeks and 8 weeks after the treatment. Oswestry Disability Index (ODI), Visual Analog Scale (VAS), Roland-Morris Disability Questionnaire (RMDQ), Timed up and go test (TUGT), trunk range of movement (Trunk ROM), Hospital Anxiety and Depression Scale (HADS) were used for the evaluation. A total of 206 subjects completed treatment, among whom 104 participants were randomized to the BSHXF group and 102 participants were randomized to the control group. There were no significant differences between groups in terms of the observed indicators (P > .05). After treatment, patients in BSHXF group obtained significant lower scores at 2-week, 4-week, 8-week of VAS, ODI, RMDQ, TUGT, Trunk ROM and HADS than the baseline data (P < .05). The ODI score was significantly lower than the control group at 2-week, 4-week, 8-week (2w: 11.30 ± 5.80 vs 14.23 ± 6.33, P < .001; 4w: 10.95 ± 4.93 vs 13.54 ± 6.35, P < .001; 8w: 10.27 ± 5.25 vs 12.84 ± 6.57, P = .002). Similarly, the scores of VAS, RMDQ, TUGT, Trunk ROM scores of the BSHXF group markedly decreased at 2, 4, and 8-week when compared to their control group (P < .05). Furthermore, no significant difference showed up in the score of HADS between the between the BSHXF and the control group after treatment (P > .05). This randomized clinical trial found that BSXHF can help significantly improve the clinical outcomes of celecoxib including pain intensity reduction and lumbar function improvement in LBP patients.

Effects of landscape pattern on water quality at multi-spatial scales in Wuding River Basin, China.

Urbanization and agricultural land use have led to water quality deterioration. Studies have been conducted on the relationship between landscape patterns and river water quality; however, the Wuding River Basin (WDRB), which is a complex ecosystem structure, is facing resource problems in river basins. Thus, the multi-scale effects of landscape patterns on river water quality in the WDRB must be quantified. This study explored the spatial and seasonal effects of land use distribution on river water quality. Using the data of 22 samples and land use images from the WDRB for 2022, we quantitatively described the correlation between river water quality and land use at spatial and seasonal scales. Stepwise multiple linear regression (SMLR) and redundancy analyses (RDA) were used to quantitatively screen and compare the relationships between land use structure, landscape patterns, and water quality at different spatial scales. The results showed that the sub-watershed scale is the best spatial scale model that explains the relationship between land use and water quality. With the gradual narrowing of the spatial scale range, cultivated land, grassland, and construction land had strong water quality interpretation abilities. The influence of land use type on water quality parameter variables was more distinct in rainy season than in the dry season. Therefore, in the layout of watershed management, reasonably adjusting the proportion relationship of vegetation and artificial building land in the sub-basin scale and basin scope can realize the effective control of water quality optimization.

The Efficacy of Perturbation-Based Balance Training Among Older Adults: A Systematic Review

Aims The aim of this systematic review was to investigate the efficacy of perturbation-based balance training in the older adults to reduce risk and number of falls. Methods Multiple databases were searched for articles published between 2012-2021. The inclusion criteria were 1) patients ≥65 years of age, 2) land-based perturbation training, 3) randomized controlled trials (RCTs), 4) PBT intervention group, 5) controlled intervention group, 5) written in English, and 6) articles scoring 6/10 (“good”) or higher on the PEDro scale. Results Six articles met the inclusion criteria with a PEDro scale range of 6-8/10. A total of 793 subjects were included across the studies. Conclusions PBT can be effective in improving various deficits predictive of falls. The effect was most pronounced in reactive balance control, balance confidence, and gait kinematics of recovery steps with mild effect in overall fall risk.

Predicting lodging severity in dry peas using UAS-mounted RGB, LIDAR, and multispectral sensors

This study investigated the feasibility of using data collected by sensors mounted onto unmanned aerial systems (UASs) and traditional classification methods (Maximum Likelihood, Mahalanobis Distance, Minimum Distance, and Adaptive Coherence Estimator) and four machine learning models (Random Forest [RF], Support Vector Machine [SVM], K-Nearest Neighbor [KNN], and Extreme Gradient Boosting [XGBOOST]) to predict the severity of dry pea lodging. Data were collected in two environments in North Dakota during the 2022 crop season, where lodging was visually estimated at the plot level using a lodging scale range of 0 to 9. Aerial images were collected using two UASs (DJI Matrice 200 and 300) during early, mid, and late stages of growth. Synthetic Minority Oversampling Technique combined with Edited Nearest Neighbors (SMOTE-ENN) was used to balance the imbalanced dataset. Different feature selection models (recursive feature elimination, lasso regression, principal component analysis, and correlation-based methods) were used and compared to identify the most important features in the dataset. Our study found that similar channels can be used interchangeably for analyzing lodging without compromising accuracy, simplifying data acquisition, and saving time and resources. The maximum plant height values obtained from LiDAR and RGB sensors showed a strong correlation with actual values. Recursive feature elimination was the most effective feature selection method for handling high-dimensional datasets. The XGBOOST model outperformed all traditional and machine learning classification models, with the lowest variation in precision values. RF showed the most pronounced overfitting among the machine learning models, while Mahalanobis distance showed the least overfitting among all traditional classification models. Overall, the study demonstrated the potential of UAS and machine learning models for predicting lodging severity in dry peas, with XGBOOST being the best-performing model.

The impacts of rising vapour pressure deficit in natural and managed ecosystems.

An exponential rise in the atmospheric vapour pressure deficit (VPD) is among the most consequential impacts of climate change in terrestrial ecosystems. Rising VPD has negative and cascading effects on nearly all aspects of plant function including photosynthesis, water status, growthand survival. These responses are exacerbated by land-atmosphere interactions that couple VPD to soil water and govern the evolution of drought, affecting a range of ecosystem services including carbon uptake, biodiversity, the provisioning of water resourcesand crop yields. However, despite the global nature of this phenomenon, research on how to incorporate these impacts into resilient management regimes is largely in its infancy, due in part to the entanglement of VPD trends with those of other co-evolving climate drivers. Here, we review the mechanistic bases of VPD impacts at a range of spatial scales, paying particular attention to the independent and interactive influence of VPD in the context of other environmental changes. We then evaluate the consequences of these impacts within key management contexts, including water resources, croplands, wildfire risk mitigationand management of natural grasslands and forests. We conclude with recommendations describing how management regimes could be altered to mitigate the otherwise highly deleterious consequences of rising VPD.

Models for the retention of duplicate genes and their biological underpinnings

Gene content in genomes changes through several different processes, with gene duplication being an important contributor to such changes. Gene duplication occurs over a range of scales from individual genes to whole genomes, and the dynamics of this process can be context dependent. Still, there are rules by which genes are retained or lost from genomes after duplication, and probabilistic modeling has enabled characterization of these rules, including their context-dependence. Here, we describe the biology and corresponding mathematical models that are used to understand duplicate gene retention and its contribution to the set of biochemical functions encoded in a genome.

PeleMP: The Multiphysics Solver for the Combustion Pele Adaptive Mesh Refinement Code Suite

Abstract Combustion encompasses multiscale, multiphase reacting flow physics spanning a wide range of scales from the molecular scales, where chemical reactions occur, to the device scales, where the turbulent flow is affected by the geometry of the combustor. This scale disparity and the limited measurement capabilities from experiments make modeling combustion a significant challenge. Recent advancements in high-performance computing (HPC), particularly with the Department of Energy's Exascale Computing Project (ECP), have enabled high-fidelity simulations of practical applications to be performed. The major physics submodels, including chemical reactions, turbulence, sprays, soot, and thermal radiation, exhibit distinctive computational characteristics that need to be examined separately to ensure efficient utilization of computational resources. This paper presents the multiphysics solver for the Pele code suite, called PeleMP, which consists of models for spray, soot, and thermal radiation. The mathematical and algorithmic aspects of the model implementations are described in detail as well as the verification process. The computational performance of these models is benchmarked on multiple supercomputers, including Frontier, an exascale machine. Results are presented from production simulations of a turbulent sooting ethylene flame and a bluff-body swirl stabilized spray flame with sustainable aviation fuels to demonstrate the capability of the Pele codes for modeling practical combustion problems with multiphysics. This work is an important step toward the exascale computing era for high-fidelity combustion simulations providing physical insights and data for predictive modeling of real-world devices.

Probing Laser‐Driven Structure Formation at Extreme Scales in Space and Time

AbstractIrradiation of solid surfaces with high intensity, ultrashort laser pulses triggers a variety of secondary processes that can lead to the formation of transient and permanent structures over a large range of length scales from mm down to the nano‐range. One of the most prominent examples are LIPSS – Laser‐Induced Periodic Surface Structures. While LIPSS have been a scientific evergreen for of almost 60 years, experimental methods that combine ultrafast temporal with the required nm spatial resolution have become available only recently with the advent of short pulse, short wavelength free electron lasers. Here, the current status and future perspectives in this field are discussed by exploiting the unique possibilities of these 4th‐generation light sources to address by time‐domain experimental techniques the fundamental LIPSS‐question, namely why and how laser irradiation can initiate the transition of a “chaotic” (rough) surface from an aperiodic into a periodic structure.

Tenecteplase for Stroke at 4.5 to 24 Hours with Perfusion-Imaging Selection

BackgroundThrombolytic agents, including tenecteplase, are generally used within 4.5 hours after the onset of stroke symptoms. Information on whether tenecteplase confers benefit beyond 4.5 hours is limited.MethodsWe conducted a multicenter, double-blind, randomized, placebo-controlled trial involving patients with ischemic stroke to compare tenecteplase (0.25 mg per kilogram of body weight, up to 25 mg) with placebo administered 4.5 to 24 hours after the time that the patient was last known to be well. Patients had to have evidence of occlusion of the middle cerebral artery or internal carotid artery and salvageable tissue as determined on perfusion imaging. The primary outcome was the ordinal score on the modified Rankin scale (range, 0 to 6, with higher scores indicating greater disability and a score of 6 indicating death) at day 90. Safety outcomes included death and symptomatic intracranial hemorrhage.ResultsThe trial enrolled 458 patients, 77.3% of whom subsequently underwent thrombectomy; 228 patients were assigned to receive tenecteplase, and 230 to receive placebo. The median time between the time the patient was last known to be well and randomization was approximately 12 hours in the tenecteplase group and approximately 13 hours in the placebo group. The median score on the modified Rankin scale at 90 days was 3 in each group. The adjusted common odds ratio for the distribution of scores on the modified Rankin scale at 90 days for tenecteplase as compared with placebo was 1.13 (95% confidence interval, 0.82 to 1.57; P=0.45). In the safety population, mortality at 90 days was 19.7% in the tenecteplase group and 18.2% in the placebo group, and the incidence of symptomatic intracranial hemorrhage was 3.2% and 2.3%, respectively.ConclusionsTenecteplase therapy that was initiated 4.5 to 24 hours after stroke onset in patients with occlusions of the middle cerebral artery or internal carotid artery, most of whom had undergone endovascular thrombectomy, did not result in better clinical outcomes than those with placebo. The incidence of symptomatic intracerebral hemorrhage was similar in the two groups. (Funded by Genentech; TIMELESS ClinicalTrials.gov number, NCT03785678.)

A guide to photosynthetic gas exchange measurements: Fundamental principles, best practice and potential pitfalls.

Gas exchange measurements enable mechanistic insights into the processes that underpin carbon and water fluxes in plant leaves which in turn inform understanding of related processes at a range of scales from individual cells to entire ecosytems. Given the importance of photosynthesis for the global climate discussion it is important to (a) foster a basic understanding of the fundamental principles underpinning the experimental methods used by the broad community, and (b) ensure best practice and correct data interpretation within the research community. In this review, we outline the biochemical and biophysical parameters of photosynthesis that can be investigated with gas exchange measurements and we provide step-by-step guidance on how to reliably measure them. We advise on best practices for using gas exchange equipment and highlight potential pitfalls in experimental design and data interpretation. The Supporting Information contains exemplary data sets, experimental protocols and data-modelling routines. This review is a community effort to equip both the experimental researcher and the data modeller with a solid understanding of the theoretical basis of gas-exchange measurements, the rationale behind different experimental protocols and the approaches to data interpretation.

The VLBA CANDELS GOODS-North Survey. II – Wide-field source catalogue comparison between the VLBA, EVN, e-MERLIN, and VLA

ABSTRACT Deep radio surveys of extragalactic legacy fields trace a large range of spatial and brightness temperature sensitivity scales, and therefore have differing biases to radio-emitting physical components within galaxies. This is particularly true of radio surveys performed at $\lesssim 1 \ \mathrm{arcsec}$ angular resolutions, and so robust comparisons are necessary to better understand the biases present in each survey. We present a multiresolution and multiwavelength analysis of the sources detected in a new Very Long Baseline Array (VLBA) survey of the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey Great Observatories Origins Deep Survey-North field. For the 24 VLBA-selected sources described in Paper I, we augment the VLBA data with EVN data, and ∼0.1–1 arcsec angular resolution data provided by Very Large Array (VLA) and enhanced-Multi Element Remotely Linked Interferometry Network. This sample includes new active galactic nuclei (AGN) detected in this field, thanks to a new source extraction technique that adopts priors from ancillary multiwavelength data. The high brightness temperatures of these sources (TB ≳ 106 K) confirm AGN cores, that would often be missed or ambiguous in lower-resolution radio data of the same sources. Furthermore, only 15 sources are identified as ‘radiative’ AGN based on available X-ray and infrared constraints. By combining VLA and VLBA measurements, we find evidence that the majority of the extended radio emission is also AGN dominated, with only three sources with evidence for extended potentially star formation-dominated radio emission. We demonstrate the importance of wide-field multiresolution (arcsecond–milliarcsecond) coverage of the faint radio source population, for a complete picture of the multiscale processes within these galaxies.

Trends in Psychological Distress and Outpatient Mental Health Care of Adults During the COVID-19 Era.

In addition to the physical disease burden of the COVID-19 pandemic, concern exists over its adverse mental health effects. To characterize trends in psychological distress and outpatient mental health care among U.S. adults from 2018 to 2021 and to describe patterns of in-person, telephone, and video outpatient mental health care. Cross-sectional nationally representative survey of noninstitutionalized adults. United States. Adults included in the Medical Expenditure Panel Survey Household Component, 2018 to 2021 (n = 86658). Psychological distress was measured with the Kessler-6 scale (range of 0 to 24, with higher scores indicating more severe distress), with a score of 13 or higher defined as serious psychological distress, 1 to 12 as less serious distress, and 0 as no distress. Outpatient mental health care use was measured via computer-assisted personal interviews. Between 2018 and 2021, the rate of serious psychological distress among adults increased from 3.5% to 4.2%. Although the rate of outpatient mental health care increased from 11.2% to 12.4% overall, the rate decreased from 46.5% to 40.4% among adults with serious psychological distress. When age, sex, and distress were controlled for, a significant increase in outpatient mental health care was observed for young adults (aged 18 to 44 years) but not middle-aged (aged 45 to 64 years) and older (aged >65 years) adults and for employed adults but not unemployed adults. In 2021, 33.4% of mental health outpatients received at least 1 video visit, including a disproportionate percentage of young, college-educated, higher-income, employed, and urban adults. Information about outpatient mental health service modality (in-person, video, telephone) was first fully available in the 2021 survey. These trends and patterns underscore the persistent challenges of connecting older adults, unemployed persons, and seriously distressed adults to outpatient mental health care and the difficulties faced by older, less educated, lower-income, unemployed, and rural patients in accessing outpatient mental health care via video. None.

Surgical outcomes of endoscopic dacryocystorhinostomy for eyes with nasolacrimal duct obstruction via tear meniscus height evaluation.

To evaluate the association of tear meniscus height (TMH) with clinical outcomes of patients who underwent endonasal dacryocystorhinostomy. We recruited 304 patients from two institutes. The TMH was measured using anterior segment optical coherence tomography before surgery. All patients underwent endoscopic DCR with lacrimal intubation stent insertion. The lacrimal stent was removed 2months after surgery. The TMH was measured at 2months and 12months after surgery. Improvements in epiphora were assessed using a visual analogue scale (range, 0-2). Recurrence was determined based on lacrimal irrigation and endoscopic evaluation results. All patients experienced improvements in subjective symptoms 2months after surgery. The mean TMH also decreased significantly compared with that before surgery. During the follow-up period, four patients experienced recurrence. The mean TMH 12months after surgery was significantly lower than that before surgery. The rate of change in the TMH was significantly associated with the use of a dacryoendoscope during sheath-guided lacrimal stent intubation at all time points. Of the 251 patients who were followed up at 12months after surgery, three reported recurrences, and 17 reported mild improvement of epiphora. The rate of change in the TMH was significantly associated with epiphora improvement. Height was also associated with epiphora improvement. Endoscopic DCR is an acceptable surgical procedure for managing nasolacrimal duct obstruction. Sheath-guided lacrimal stent intubation using a dacryoendoscope resulted in a greater reduction in postoperative TMH compared to the blind insertion technique, which may lead to favorable clinical outcomes.
