Long-term nitrogen isotope dynamics in Encelia farinosa reflect plant demographics and climate.

While plant δ15 N values have been applied to understand nitrogen dynamics, uncertainties regarding intraspecific and temporal variability currently limit their application. We used a 28-year record of δ15 N values from two Mojave Desert populations of Encelia farinosa to clarify sources of population-level variability. We leveraged >3,500 foliar δ15 N observations collected alongside structural, physiological, and climatic data to identify plant and environmental contributors to δ15 N values. Additional sampling of soils, roots, stems, and leaves enabled assessment of the distribution of soil nitrogen content and δ15 N, intra-plant fractionations, and relationships between soil and plant δ15 N values. We observed extensive within-population variability in foliar δ15 N values and found plant age and foliar %N to be the strongest predictors of individual δ15 N values. There were consistent differences between root, stem, and leaf δ15 N values (spanning c. 3‰), but plant and bulk soil δ15 N values were unrelated. Plant-level variables played a strong role in influencing foliar δ15 N values, and interannual relationships between climate and δ15 N values were counter to previously recognized spatial patterns. This long-term record provides insights regarding the interpretation of δ15 N values that were not available from prior large-scale syntheses, broadly enabling more effective application of foliar δ15 N values.
Influence of different phytoremediation on soil microbial diversity and community composition in saline-alkaline land

Abstract Soil salinization is one main environmental factor restricting plant growth and agricultural productivity. However, phytoremediation is one of the important means to improve saline-alkali soil by planting halophytes or salt-tolerant plants. In order to study whether there are differences among soil microorganisms in different phytoremediation, the effects of four plants, including alfalfa (MX), oil sunflower (YK), maize (YM) and ryegrass (HMC) on soil physicochemical properties, enzyme activity and microbial community diversity and composition were investigated in this study and the relationships between microbial community structure and soil physicochemical properties, enzyme activity were analyzed. The results showed that all plants treatments significantly decreased pH, TS (total saltinity) and BD (bulk density), while increased OM (organic matter), TN (total nitrogen), AN (available nitrogen), TP (total phosphorus), AP (available phosphorus), TK (total potassium) and TPOR (total porosity), and the number of nitrite bacteria reduced by planting at the same time. Except for YM, other treatments significantly increased the number of nitrifying and denitrifying bacteria compared with CK, while only YK increased that of fungi. Additionally, all plants increased the activity of nitrite reductase and decreased that of urease. More interestingly, plants treatments shifted microbial community compositions, and only YM significantly decreased the bacterial diversity and increased the fungal diversity. Redundancy analysis suggested that TK, pH, BD, TS, AN, OM and nitrite reductase, lignin peroxidase were the key environmental factors that shaped the bacterial community structure, while that of fungi was mainly driven by OM, nitrite reductase, urease and lignin peroxidase. The results indicated that MX and YM are the best choice for remediation of saline-alkali soil. These data can provide certain theoretical basis for the further restoration of saline-alkali land. HIGHLIGHTS The effects of different phytoremediation on microbial diversity and community structure were different. Phytoremediation can significantly decreased pH, TS and BD, while increased OM, TN, AN, TP, AP, TK and TPOR in saline-alkali soil. All plants increased the activity of nitrite reductase and decreased the activity of urease.
Lesion evidence for a causal role of the insula in aversion to social inequity

Abstract Humans resist unequal distributions of goods in their social interactions, even if it requires foregoing personal gains. Functional neuroimaging studies implicate the insula in this aversion to social inequity and in fairness-related decisions, but a causal contribution has not yet been established. We compared the responses of 30 patients with lesions to the insula on a multiple-trial version of the one-shot Ultimatum Game, a neuroeconomic social exchange paradigm where a sum of money is split between two players, to those of 30 matched patients with brain injuries sparing the insula. Insula lesion patients accepted offers of an unequal disadvantageous split significantly more often than comparison lesion patients. Computational modeling confirmed that this difference in choice behavior was due to decreased aversion to disadvantageous inequity following insula damage, rather than due to increased decision noise or non-consideration of inequity. Our results provide novel evidence that the insula is causally involved in aversion to inequity and in value-based choices in the context of social interactions.
Flexible fast-mapping: Deaf children dynamically allocate visual attention to learn novel words in American Sign Language.

Word learning in young children requires coordinated attention between language input and the referent object. Current accounts of word learning are based on spoken language, where the association between language and objects occurs through simultaneous and multimodal perception. In contrast, deaf children acquiring American Sign Language (ASL) perceive both linguistic and non-linguistic information through the visual mode. In order to coordinate attention to language input and its referents, deaf children must allocate visual attention optimally between objects and signs. We conducted two eye-tracking experiments to investigate how young deaf children allocate attention and process referential cues in order to fast-map novel signs to novel objects. Participants were deaf children learning ASL between the ages of 17-71 months. In Experiment 1, participants (n = 30) were presented with a novel object and a novel sign, along with a referential cue that occurred either before or after the sign label. In Experiment 2, a new group of participants (n = 32) were presented with two novel objects and a novel sign, so that the referential cue was critical for identifying the target object. Across both experiments, participants showed evidence for fast-mapping the signs regardless of the timing of the referential cue. Individual differences in children's allocation of attention during exposure were correlated with their ability to fast-map the novel signs at test. This study provides first evidence for fast-mapping in sign language, and contributes to theoretical accounts of how word learning develops when all input occurs in the visual modality.

Escherichia coli bloodstream infections in the western interior of British Columbia, Canada: a population-based cohort study

Abstract Our population-based study objectives were to describe characteristics and outcomes of Escherichia coli bloodstream infections (BSIs), and to evaluate factors associated with outcomes. We included incident E. coli BSIs from western interior residents (British Columbia, Canada; 04/2010–03/2020). We obtained data including patient demographics, location of onset, infection focus, Charlson comorbidity index (CCI), antimicrobial resistance, 30-day all-cause mortality and length of hospital stay (LOS). Using multivariable logistic regression models fitted with generalised estimating equations, we estimated factors associated with 30-day mortality and long post-infection LOS (>75th percentile). We identified 1080 incident E. coli BSIs in 1009 patients. The crude incidence and 30-day mortality rates were 59.1 BSIs and 6.8 deaths/100 000 person-years, respectively. The 30-day case fatality risk was 11.5%. Compared to community-acquired E. coli BSIs, either healthcare-associated or nosocomial cases had higher odds of 30-day mortality. Older cases, non-urogenital BSI foci and CCI ⩾ 3 had higher odds of 30-day mortality compared to younger cases, urogenital foci and CCI < 3. In patients that survived to discharge, those with extended-spectrum β-lactamase (ESBL)-producing E. coli BSIs, nosocomial BSIs, and CCI ⩾ 3 had higher odds of long post-infection LOS compared to those with non-ESBL-producing, community-acquired and healthcare-associated, and CCI < 3. There is a substantial disease burden from E. coli BSIs.
COVID‐19 and the Liver: Lessons Learnt from the EAST and the WEST, A Year Later

Globally, the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2 virus) has been a major cause for significant morbidity and mortality. Since the start of the pandemic, several hepato‐biliary manifestations in coronavirus disease 2019 (COVID‐19) have been described and unique considerations raised. The review aims to summarize the pathogenesis and hepato‐biliary manifestations in COVID‐19 and discuss the similarities, contrasting features and disease‐specific management across a range of hepato‐biliary diseases from the EAST and the WEST. Published studies and regional society guidelines from the EAST and the WEST were comprehensively reviewed and summarized. A wide range of hepato‐biliary manifestations, including the infrequent and chronic manifestation of cholangiopathy, has been observed in COVID‐19. The pathogenesis of liver injury is multifactorial and with scant evidence for a direct SARS‐CoV‐2 infection of the liver. Patients with non‐alcoholic fatty liver disease, cirrhosis, and liver cancer are potentially at increased risk for severe COVID‐19, and there are unique considerations in chronic hepatitis B or C, hepatocellular carcinoma, and in those immunosuppressed such as autoimmune hepatitis or liver transplant recipients. With the surges in SARS‐CoV‐2 infection, liver transplant activity has variably been impacted. Preliminarily, SARS‐CoV‐2 vaccines appear to be safe in those with chronic liver disease and in transplant recipients, while emerging data suggest the need for a third dose in immunosuppressed patients. In conclusion, patients with chronic liver disease, particularly cirrhosis, and liver transplant recipients, are vulnerable to severe COVID‐19. Over the past year, several unique considerations have been highlighted across a spectrum of hepato‐biliary diseases. Vaccination is strongly recommended for those with chronic liver disease and liver transplant recipients.
A Combined Chemical, Computational, and In Vitro Approach Identifies SBL-105 as Novel DHODH Inhibitor in Acute Myeloid Leukemia Cells

Inhibition of the dihydroorotate dehydrogenase (DHODH) has been successful at the preclinical level in controlling myeloid leukemia. However, poor clinical trials warrant the search for new potent DHODH inhibitors. Herein we present a novel DHODH inhibitor SBL-105 effective against myeloid leukemia. Chemical characteristics were identified by 1H NMR, 13C NMR, and mass spectroscopy. Virtual docking and molecular dynamic simulation analysis were performed using the automated protocol with AutoDock-VINA, GROMACS program. Human-recombinant (rh) DHODH was used for enzyme inhibition study. THP-1, TF-1, HL-60, and SKM-1 cell lines were used. MTT assay was used to assess cell viability. Flow cytometry was employed for cell cycle, apoptosis, and differentiation analysis. Chemical analysis identified the compound to be 3-benzylidene-6,7-benz-chroman-4-one (SBL-105). The compound showed high binding efficacy toward DHODH with a ΔGbinding score of −10.9 kcal/mol. Trajectory analysis indicated conserved interactions of SBL-105–DHODH to be stable throughout the 200-ns simulation. SBL-105 inhibited rh DHODH with an IC50 value of 48.48 nM. The GI50 values of SBL-105 in controlling THP-1, TF-1, HL-60, and SKM-1 cell proliferations were 60.66, 45.33, 73.98, and 86.01 nM, respectively. A dose-dependent increase in S-phase cell cycle arrest and total apoptosis was observed by SBL-105 treatment in both cell types, which were reversed in the presence of uridine. The compound also increased the differentiation marker CD11b-positive populations in both THP-1 and TF-1 cells, which were decreased under uridine influence. SBL-105, a novel DHODH inhibitor, identified using computational and in vitro analysis, was effective in controlling AML cells and needs attention for further preclinical developments.
Mindfulness-based therapy versus cognitive behavioral therapy for people with anxiety symptoms: a systematic review and meta-analysis of random controlled trials.

BACKGROUND Mindfulness-based interventions (MBIs) and cognitive behavioral therapy (CBT) have both been shown to be effective treatment approaches for anxiety. The purpose of this paper was to directly investigate the ability of MBIs and CBT to improve anxiety symptoms (primary outcome), as well as depression symptoms and sleep quality (second outcome). METHODS We searched the following electronic databases from 1st December, 2019 to 14th January 2021: English databases including PubMed, PsycINFO, Web of Science, the Cochrane Library, Elsevier, Springer Link, Wiley Online Library, ClinicalTrails, and Embase, and Chinese database including CNKI, WANFANG, and CQVIP. The eligibility criteria included the following: (I) patients with anxiety disorders or symptoms of anxiety; and those with physical or mental disorders with comorbid anxiety symptoms; (II) randomized controlled trial (RCT) design; (III) the treatment group received MBIs; (IV) the control group received CBT; and (V) the treatment outcomes were anxiety, depression, and sleep quality. RESULTS In total, 4,095 abstracts were reviewed. Of these, the full-texts of 45 articles were read in detail; and 11 RCTs were finally included in the analysis. Upon completion of MBIs and CBT group sessions, the study outcomes (mean anxiety, depression, and sleep quality scores) revealed no difference between MBIs and CBT with regards to anxiety, depression, and sleep quality post-intervention. Subgroup analysis was also performed, and the results indicated that MBIs may provide a small advantage for people with anxiety symptoms compared to CBT [standard mean difference (SMD): -0.36, 95% confidence interval (CI): -0.66 to -0.06], while the CBT group demonstrated a small comparative advantage for anxiety in the Liebowitz Social Anxiety Scale (LSAS) and Social Phobia Inventory (SPIN) scales, as well as mindfulness-based stress reduction (MBSR) in the types of MBIs (LSAS: SMD: 0.35, 95% CI: 0.08 to 0.63; SPIN: SMD: 0.51, 95% CI: 0.11 to 0.92; MBSR: SMD: 0.41, 95% CI: 0.07 to 0.74). DISCUSSION There was no significant difference between MBIs and CBT in terms of the treatment outcomes of anxiety, depression, and sleep quality. MBIs could be used as an alternative intervention to CBT for anxiety symptoms. TRIAL REGISTRATION This meta-analysis was conducted in line with the PRISMA guideline and was registered at PROSPERO https://www.crd. york.ac. uk/PROSPERO/ (CRD42021219822).
Using Accountable Care Teams to Improve Timely Discharge: A Pilot Study

Background and Objective: Hospitals worldwide are faced with the problem of discharging patients on time. Delayed discharge creates domino effects with significant implications for hospitals. The accountable care team (ACT) is a multidisciplinary, unit-based approach to identifying opportunities to improve patient care and address inefficiencies in care delivery and throughput, including assuring timely discharges. In response to concerns about emergency department boarding times and delays in timely discharge, the ACT recommended a set of strategies to improve communication across team members and to reduce wait times for transportation within and outside the hospital. Collectively these strategies were thought to increase the proportion of patients discharged on time. In this article, we describe and assess changes in timely discharge resulting from the implementation of strategies recommended by the ACT. Methods: This study uses a retrospective, quasi-experimental design to compare the percentage of discharges by 1 pm of hospital units implementing the ACT intervention to those units not implementing the intervention. Median discharge time was compared pre- and post-implementation using the Wilcoxon rank sum test. Difference-in-differences modeling was employed to assess whether changes in the percentage of discharges by 1 pm differed between units implementing the intervention and units not implementing the intervention. Results: One month post-implementation, the percentage discharged by 1 pm was statistically significantly higher for units implementing the intervention (53.6%) compared with comparison units (22.5%, t = −4.48, P < .01). Statistically significant differences in the percentage discharged by 1 pm were also seen at 3 and 6 months post-implementation. The median discharge time showed a statistically significant decrease by 77 minutes from the baseline to intervention period (P < .01). Conclusion: The result from the study suggests that ACTs can be used to develop approaches aimed at improving patient care in general, and discharge efficiencies in particular. Health care organizations are encouraged to utilize and then evaluate the specific activities of multidisciplinary teams aimed at developing recommendations for practice improvement.
Does the horizontal condylar angle have a relationship with temporomandibular joint osteoarthritis and condylar position? A cone-beam computed tomography study.

BACKGROUND To evaluate the relationship between the horizontal condylar angle (HCA), temporomandibular joint osteoarthritis (TMJ OA), and condylar position on cone-beam computed tomography (CBCT) images. MATERIALS AND METHODS Based on TMJ OA, joints were classified as affected and the unaffected. According to the OA condition of their joints, three groups of patients were formed: control group (n = 159, 41.1%), unilateral group (n = 121, 31.3%), and bilateral group (n = 107, 27.6%). In total, the HCAs of 774 TMJs of 387 patients were measured and their condylar positions were determined as concentric (n = 184, 23.8%), posterior (n = 338, 43.7%), and anterior (n = 252, 32.5%). RESULTS The mean HCA of the bilateral group (22.7° ± 7.6°) was greater than those in both the control (19.5° ± 6.4°) and the unilateral (20.5° ± 6.5°) groups (p < 0.05). However, the difference was not statistically significant between the control and unilateral group (p > 0.05). In total patients, unlike the unilateral group, the affected joints had a greater mean HCA than the unaffected joints (p < 0.05). The mean HCAs of the joints according to the condylar position were as concentric: 20.6° ± 6.7°, posterior: 21.1° ± 7.8°, and anterior: 20.2° ± 7.9° (p > 0.05). CONCLUSIONS While the HCA increased in the presence of TMJ OA, no relationship was found between HCA and three different condylar positions.
To be happy and behave in a healthier way. A longitudinal study about gender differences in the older population

Abstract Introduction Subjective well-being plays a key role in health. The objectives of this study are to analyse the longitudinal associations between subjective well-being dimensions and healthy behaviours, and to examine gender differences. Method A representative sample of 1,190 Spanish non-institutionalised adults aged 50+ were interviewed over a 6-year follow-up period. The Cantril scale was used to measure evaluative well-being. The Day Reconstruction Method measured experienced well-being. The Global Physical Activity Questionnaire was used, whereas fruit and vegetables, tobacco and alcohol consumption, and sleep quality were self-reported. The Generalised Estimating Equation was calculated. Results Women show significantly worse subjective well-being than men longitudinally. Higher scores in life satisfaction and positive affect were significantly related to a higher level of physical activity and better-quality sleep for both women and men. Associations between a higher life satisfaction and an adequate intake of fruits and vegetables and being a non-smoker was only found in women (OR = 1.05; 95% IC = 1.00, 1.10 and OR = 1.16; 95% IC = 1.09, 1.23, respectively). Conclusion Subjective well-being levels and frequencies in healthy behaviours are different in women and men. Subjective well-being interventions should take into account these differences in the frequency of healthy-unhealthy behaviours.
Familial History of Autoimmune Disorders Among Patients With Pediatric Multiple Sclerosis

Background and Objective The objective of this study was to determine whether family members of patients with pediatric multiple sclerosis (MS) have an increased prevalence of autoimmune conditions compared with controls. Methods Data collected during a pediatric MS case-control study of risk factors included information about various autoimmune diseases in family members. The frequency of these disorders was compared between cases and controls. Results There was an increased rate of autoimmune diseases among family members of pediatric MS cases compared with controls with first-degree history of MS excluded (OR = 2.27, 95% CI 1.71–3.01, p < 0.001). There was an increased rate of MS among second-degree relatives of pediatric MS cases compared with controls (OR = 3.47, 95% CI 1.36–8.86, p = 0.009). The OR for MS was 2.64 when restricted to maternal relatives and 6.37 when restricted to paternal relatives. Discussion The increased rates of autoimmune disorders, including thyroid disorders and MS among families of patients with pediatric MS, suggest shared genetic factors among families with children diagnosed with pediatric MS.
Copper uptake, physiological response, and phytoremediation potential of Brassica juncea under biochar application

Abstract Biochar can enhance the phytoremediation of copper-contaminated soils by improving soil quality and increasing plant growth. However, the impact of biochar varies with the biomass feedstock and soil condition. Our study investigated the effect of biochar from orange bagasse-OBB and coconut husk-CHB and two copper concentrations (0.17 mg kg−1-CLS soil; 100 mg kg−1- CTS soil) on plant growth, copper uptake, and physiological response of Brassica juncea. The low- and high-Cu soils were also tested without biochar. We evaluated plant biomass, plant Cu, N and P, chlorophyll content, and chlorophyll’s transient fluorescence. Plant growth was meager without biochar, indicating that the high Cu concentration was not the only limiting factor. Biochar (OBB and CHB) increased shoot mass by 300–574% and root mass by 50–2900%, and improved chlorophyll content and photosynthetic activity by 6–16%. Both biochars were efficient in the low-Cu soil as they increased plant biomass, shoot copper concentration, and translocation factor. In the high-Cu soil, both biochars increased plant biomass and copper uptake and reduced shoot copper concentration and translocation factor. The CHB and OBB removed 342% and 783% more Cu from the contaminated soil than the Control; therefore, the OBB was proven to be the best choice for phytoremediation. Novelty statement Our study showed that the orange bagasse biochar can be successfully applied for the phytoremediation of copper-contaminated soils using Brassica juncea. The orange bagasse biochar was effective regardless of the copper level in the soil, removing twice as much copper as the coconut biochar; therefore, it can speed up the process and reduce the time needed to clean up the site. Highlights Biochar significantly improved the plant’s physiological response Biochar increased plant growth and copper uptake in the contaminated soil Translocation factor was increased in the clean soil and reduced in the contaminated soil Biochar from orange bagasse is more effective than coconut husk for phytoremediation
