By examining the microscopic interactions of publications and citations, our complex systems approach is able to identify the macroscopic patterns of a controversial concept’s diffusion.
The aim of the present study was to investigate how the initial phase of the COVID-19 pandemic affected the hospital stroke management and research in Norway.
All neurological departments with a Stroke Unit in Norway (n=17) were invited to participate in a questionnaire survey. The study focused on the first lockdown period, and all questions were thus answered in regard to the period between 12 March and 15 April 2020.
The responder rate was 94% (16/17). Eighty-one % (13/16) reported that the pandemic affected their department, and 63% (10/16) changed their stroke care pathways. The number of new acute admissions in terms of both strokes and stroke mimics decreased at all 16 departments. Fewer patients received thrombolysis and endovascular treatment, and multidisciplinary stroke rehabilitation services were less available. The mandatory 3months of follow-up of stroke patients was postponed at 73% of the hospitals. All departments conducting stroke research reported a stop in ongoing projects.
In Norway, hospital-based stroke care and research were impacted during the initial phase of the COVID-19 pandemic, with likely repercussions for patient care and outcomes. In the future, stroke departments will require contingency plans in order to protect the entire stroke treatment chain.

How do learners discriminate among candidate causes? The current studies examine whether counterfactuals help 5-year olds (N = 120) select between competing hypotheses and compares the effectiveness of these prompts to a related scaffold. Epigenetic inhibitor ic50 In Experiment 1, counterfactuals support evidence evaluation, leading children to privilege and extend the cause that accounted for more data. In Experiment 2, the hypothesis that accounted for the most evidence was pitted against children’s prior beliefs. Children who considered alternative outcomes privileged the hypothesis that accounted for more observations, whereas those who explained relied on prior beliefs. Findings demonstrate that counterfactuals recruit attention to disambiguating evidence and outperform explanation when data contrast with existing beliefs.Bionanotechnology has increasingly gained attention in biomedical fields as antifungal and antibiofilm agents. In this study, biosynthesized silver nanoparticles (bio-AgNPs) using aqueous Eucalyptus camaldulensis leaf extract were successfully performed by a one-step green approach. Spherical-shaped nanoparticles, approximately 8.65 nm, exhibited noncytotoxicity to erythrocytes, HeLa, and HaCaT cells. The synthesized nanoparticles showed strong fungicidal activity ranging from 0.5 to 1 µg/ml. The nanoparticles affected Candida adhesion and invasion into host cells by reduced germ tube formation and hydrolytic enzyme secretion. Inhibitory effects of bio-AgNPs on Candida biofilms were evaluated by the prevention of yeast-to-hyphal transition. A decrease in cell viability within mature biofilm demonstrated the ability of bio-AgNPs to penetrate into the extracellular matrix and destroy yeast cell morphology, leading to cell death. Molecular biology study on biofilms confirmed downregulation in the expression of genes ALS3, HWP1, ECE1, EFG1, TEC1, ZAP1, encoding hyphal growth and biofilm development and PLB2, LIP9, SAP4, involved in hydrolytic enzymes. In addition to candida treatment, the bio-AgNPs could be applied as an antioxidant to protect against oxidative stress-related human diseases. The findings concluded that bio-AgNPs could be used as an antifungal agent for candida treatment, as well as be incorporated in medical devices to prevent biofilm formation.Latent HIV-1 proviruses are capable of reactivating productive lytic infection, but the precise molecular mechanisms underlying emergence from latency are poorly understood. In this study, we determined the contribution of the transcription factors NF-κB, NFAT, and AP-1 in the reactivation of latent HIV following T-cell receptor (TCR) activation using Jurkat T-cell clones harboring single latent HIV proviruses. Our findings demonstrate that during reactivation from latency, NF-κB enhances HIV transcription while NFAT inhibits it by competing with NF-κB for overlapping binding sites on the HIV long terminal repeat (LTR). We have also demonstrated for the first time the molecular contribution of AP-1 in the reactivation of HIV from latency, whereby AP-1 synergizes with NF-κB to regulate HIV transcriptional elongation following TCR activation.The Language ENvironment Analysis system (LENA) records children’s language environment and provides an automatic estimate of adult-child conversational turn count (CTC). The present study compares LENA’s CTC estimate to manually coded CTC on a sample of 70 English-speaking infants recorded longitudinally at 6, 10, 14, 18, and 24 months of age. At each age, LENA’s CTC was significantly higher than manually coded CTC (all ps less then .001, Cohen’s ds 0.9-2.05), with the largest discrepancies between the two methods observed at younger ages. The Limits of Agreement Analyses confirm wide disagreements between the two methods, highlighting potential problems with automatic measurement of parent-infant verbal interaction. These findings suggest that future studies should validate LENA’s CTC estimates with manual coding.
To evaluate the sensitivity and specificity of the 6-item Identify Chronic Migraine screener (ID-CM), designed to improve the detection of chronic migraine (CM).
CM is often undertreated and underdiagnosed. Survey-based studies have found that approximately 75-80% of people meeting criteria for CM do not report having received an accurate diagnosis.
This study used claims data of patients enrolled in a large medical group who had at least one medical claim with an International Classification of Diseases 9th/10th revision diagnostic code for migraine in the 12-month prescreening period. The Identify Chronic Migraine survey was administered by e-mail, in-person, or over the telephone to all enrolled patients. A Semi-Structured Diagnostic Interview (SSDI) was administered by telephone by a trained physician. The ID-CM(6) and SSDI classifications of CM status were compared to evaluate sensitivity and specificity of the ID-CM(6) screening tool.
The analysis of the ID-CM(6) screening tool included 109 patients, with 65/109 (59.
