The human pathogenic fungus Candida albicans is a frequent cause of mucosal infections. Although the ability to transition from the yeast to the hypha morphology is essential for virulence, hypha formation and host cell invasion per se are not sufficient for the induction of epithelial damage. Rather, the hypha-associated peptide toxin, candidalysin, a product of the Ece1 polyprotein, is the critical damaging factor. While synthetic, exogenously added candidalysin is sufficient to damage epithelial cells, the level of damage does not reach the same level as invading C. albicans hyphae. Therefore, we hypothesized that a combination of fungal attributes is required to deliver candidalysin to the invasion pocket to enable the full damaging potential of C. albicans during infection. Utilising a panel of C. albicans mutants with known virulence defects, we demonstrate that the full damage potential of C. albicans requires the coordinated delivery of candidalysin to the invasion pocket. This process requires appropriate epithelial adhesion, hyphal extension and invasion, high levels of ECE1 transcription, proper Ece1 processing and secretion of candidalysin. To confirm candidalysin delivery, we generated camelid VH Hs (nanobodies) specific for candidalysin and demonstrate localization and accumulation of the toxin only in C. albicans-induced invasion pockets. In summary, a defined combination of virulence attributes and cellular processes is critical for delivering candidalysin to the invasion pocket to enable the full damage potential of C. albicans during mucosal infection. TAKE AWAYS Candidalysin is a peptide toxin secreted by C. albicans causing epithelial damage. Candidalysin delivery to host cell membranes requires specific fungal attributes. Candidalysin accumulates in invasion pockets created by invasive hyphae. Camelid nanobodies enabled visualisation of candidalysin in the invasion pocket.
Conflicting information on potential benefits of drugs as well as reports on hypothetical harm of commonly used drugs in COVID-19 treatment have challenged clinicians and healthcare systems. We analyzed the change in ambulatory drug utilization before, during, and after the first wave of the pandemic in 2020.

We explored dispensing data of nearly 19 000 pharmacies at the expense of the statutory health insurance funds covering 88% of Germany's population. We analyzed utilization of publicly discussed drugs with conflicting information. Drug utilization as number of packages dispensed per week from January to June 2020, reflecting 314 million claims, was compared with 2019.

Utilization of hydroxychloroquine increased +110% during March 2020 and then slightly decreased until week April 13-19. Renin-angiotensin-aldosterone system inhibitors and simvastatin/atorvastatin increased, +78% and +74%, respectively, and subsequently decreased below 2019 levels. Utilization of azithromycin and all systemic antibiotover- and underprescribing and off-label use as well as drug shortages during a public health crisis.
During the initial phase of the COVID-19 pandemic, many people with disabilities living in home care facilities could not receive visitors. The use of virtual social contact has been recommended by health authorities. This systematic review examined the scientific evidence of the use and feasibility of information and communication technology (ICT) for social contact by people with intellectual disabilities living in care facilities, and potential effects on well-being.

Five databases were searched using traditional systematic screening and machine-learning supported screening. Findings are presented in a narrative synthesis using thematic analysis.

Nine studies were included. We described three themes means of ICT used for social contact; effects on well-being; and benefits, barriers, and preconditions.

Engaging in virtual social contact may be feasible for people with severe to mild intellectual disabilities, but there is little concrete evidence that this can be used as an alternative for in-person contact.

The aim of this study was to characterise heterogeneity in neuropsychological and socio-emotional task performance in young women with anorexia nervosa (AN) using hierarchical cluster analysis. Further, we aimed to test whether cognitive profiles were associated with differences in clinical variables (body mass index, illness duration and age at diagnosis), psychopathology (eating disorder, autistic symptoms, anxiety and depression) and functional impairment.

Set-shifting, central coherence and theory of mind abilities were measured in 118 women with acute or remitted AN. A hierarchical cluster analysis using Ward's method with a Euclidean distance measure was performed with the neuropsychological and socio-emotional variables. Differences between clusters were assessed using ANOVAs.

Four clusters emerged, with significant differences in neuropsychological and socio-emotional task performance. There were no significant differences between clusters in clinical variables, psychopathology or functional impairment, however, these analyses lacked power due to small cluster sizes.

Our results demonstrate significant heterogeneity in cognitive profiles in AN, supporting a more personalised approach to treatment. Studies in larger samples are required to establish whether these variables map onto clinically significant differences in aetiology, clinical presentation, comorbidity patterns and/or treatment responses.

The pathophysiological changes in the remote myocardium after acute myocardial infarction (MI) remains less understood.

To assess the inflammation in the remote myocardium post-MI and its association with left ventricular (LV) remodeling using T2 mapping.

Prospective.

Twelve pigs at 3-day post-MI, 6 pigs at 3-month post-MI, 6 healthy pigs; 54 patients at 3-day and 3-month post-MI, 31 healthy volunteers; FIELD STRENGTH/SEQUENCE A 3T MRI/ steady-state free-precession sequence for T2 mapping (animals 0, 30, and 55 msec; human 0, 25, and 55 msec), phase-sensitive inversion recovery gradient echo for late gadolinium enhancement (LGE), balanced steady free-precession sequence for cine.

Infarcted myocardium was defined on LGE, remote T2 was measured on T2 maps. LV remodeling was evaluated as LV end-diastolic volume change index between two scans using cine. CD68 staining was conducted to detect monocyte/macrophage.

Student-t test and one-way ANOVA were used to compare remote T2 with normal controls. The association of remote T2 with LV remodeling was assessed using linear regression. P values of <0.05 were used to denote statistical significance.

Compared with healthy pigs, remote T2 significantly increased from 3 days to 3months post-MI (31.43 ± 0.67 vs. 33.53 ± 1.15 vs. 36.43 ± 1.07 msec). learn more CD68 staining demonstrated the inflammation in remote myocardium post-MI but not in healthy pigs. Significant remote myocardial alterations in T2 were also observed in human group (40.51 ± 1.79 vs. 41.94 ± 1.14 vs. 42.52 ± 1.71 msec). In patients, the 3-month remote T2 (β=0.432) and remote T2 variation between two scans (β=0.554) were both independently associated with LV remodeling.

T2 mapping could characterize the abnormalities in the remote myocardium post-MI, which was potentially caused by the inflammatory response. Moreover, variations in remote T2 were associated with LV remodeling.

1 TECHNICAL EFFICACY Stage 3.A new family of carbon-bound boron enolates, generated by a kinetically controlled halogen exchange between chlorocatecholborane and silylketene acetals, is described. These C-boron enolates are demonstrated to activate 1,3-enyne substrates in the presence of a Pd(0)/Senphos ligand complex, resulting in the first examples of a carboboration reaction of an alkyne with enolate-equivalent nucleophiles. Highly substituted dienyl boron building blocks are produced in excellent site-, regio-, and diastereoselectivity by the described catalytic cis -carboboration reaction.Marine microbes often show a high degree of physiological or ecological diversity below the species level. This microdiversity raises questions about the processes that drive diversification and permit coexistence of diverse yet closely related marine microbes, especially given the theoretical efficiency of competitive exclusion. Here, we provide insight with an 8-year time series of diversity within Synechococcus, a widespread and important marine picophytoplankter. The population of Synechococcus on the Northeast U.S. Shelf is comprised of six main types, each of which displays a distinct and consistent seasonal pattern. With compositional data analysis, we show that these patterns can be reproduced with a simple model that couples differential responses to temperature and light with the seasonal cycle of the physical environment. These observations support the hypothesis that temporal variability in environmental factors can maintain microdiversity in marine microbial populations. We also identify how seasonal diversity patterns directly determine overarching Synechococcus population abundance features.
In our study, we aimed to investigate whether end-expiratory vena cava inferior (expVCI) diameter and vena cava inferior collapsibility index predicted post-spinal hypotension in geriatric patients undergoing spinal anaesthesia (SA), the correlation between them and other parameters.

Our prospective study included the American Society of Anesthesiologists (ASA) I-4, 73 patients over 65years of age, who were scheduled for operation using SA. According to the expVCI diameter displayed with ultrasonographic (USG) before SA, patients with an expVCI diameter less than 1.8cm previously determined as the threshold value are grouped as 1 (small-VCI) group, those greater than 1.8cm as 2 (large-VCI) group. Demographic characteristics of the patients, comorbidities, duration and type of operation, basal (preoperative) heart rate, systolic, diastolic, mean blood pressure, peripheral oxygen saturation values before SA and after SA in supine position (0minute) and 5th, 10th, 15th, 20th, 25th, 30th min and preoperative value measured by USG before SA in older adults is effective in predicting post-spinal hypotension with lactate and pH values, which are among the blood gas parameters, and expVCI can be preferred to invasive methods because of its noninvasive, easy and fast application.
Severe asthma is a complex disease. Transcriptomic profiling has contributed to understanding the pathogenesis of asthma, especially type-2 inflammation. However, there is still poor understanding of non-type-2 asthma, and consequently, there are limited treatment options.

The aim of this study was to identify differentially expressed genes (DEGs) and pathways in endobronchial biopsies associated with inflammatory phenotypes of severe asthma.

This cross-sectional study examined endobronchial biopsies from 47 adults with severe asthma (neutrophilic asthma (NA) n=9, eosinophilic asthma (EA) n=22 and paucigranulocytic asthma (PGA) n=16) and 13healthy controls (HC). RNA was extracted and transcriptomic profiles generated (Illumina Humanref-12V4) and analysed using GeneSpring GX14.9.1. Pathway identification using Ingenuity Pathway Analysis.

NA had the most distinct profile, with signature of 60 top-ranked DEGs (FC >±2) including genes associated with innate immunity response, neutrophil degranulation and IL-10signalling.
