Furthermore, FA diet abrogated TGFβ and NOX4 expression, disrupting the feed-forward loop to inactivate TGFβ/NOX4/DHFR/eNOS uncoupling axis in vivo and in vitro, while PTIO, a NO scavenger, reversed this effect in cultured human aortic endothelial cells (HAECs). Besides, expression of the rate limiting H4B synthetic enzyme GTP cyclohydrolase 1 (GTPCHI), was downregulated in Fbn1C1039G/+ mice at baseline. In cultured HAECs, RNAi inhibition of fibrillin resulted in reduced GTPCHI expression, while this response was abrogated by anti-TGFβ, indicating TGFβ-dependent downregulation of GTPCHI in response to fibrillin deficiency. Taken together, our data for the first time reveal that uncoupled eNOS plays a central role in TAA formation, while anti-TGFβ and FA diet robustly abolish aneurysm formation via inactivation of a novel TGFβ/NOX4/DHFR/eNOS uncoupling/TGFβ feed-forward pathway. Correction of fibrillin deficiency is additionally beneficial via preservation of GTPCHI function.

Many elderly patients are confined to treatment with vitamin K antagonists (VKA) instead of direct oral anticoagulants (DOACs). However, quality of VKA treatment declines with age. This might be caused by the lower dose requirements with increasing age, which result in relatively large day-by-day VKA dose differences. Therefore, more precise dosing with smaller dose increments might improve quality of VKA treatment in the elderly.

We randomised 80 elderly patients (≥80years, using 0.5-2mg acenocoumarol daily) to either conventional dosing with 1.0mg acenocoumarol increments, or more precise dosing with 0.5mg increments, to assess effect sizes and feasibility of a larger trial. We compared changes in the time in therapeutic range (TTR), INR variability and anticoagulation-related quality of life (measured with the PACT-Q) between treatment groups.

Overall, baseline TTR was 61.3±19.2. After six study months, TTR had improved to 69.5±19.7 in the precise dosing group versus 67.7±21.2 in the conventional dosing group (absolute difference 3.4 (95% CI -6.7 to 13.6)). The between-groups difference in INR variability was not assessed because of baseline differences. PACT-Q convenience declined slightly with more precise dosing, compared with conventional dosing 2.1/100 (95% CI 0.5-3.7). Olaparib Satisfaction decreased equally in both groups with -6.4±8.6/100. Four dosing errors occurred three with precise and one with conventional dosing.

Although more precise dosing of acenocoumarol leads to a slightly higher TTR, this effect is too small to convey a relevant clinical benefit and could be abolished by the increased risk of medication errors.

To investigate the impact of atrial fibrillation/flutter (AF) on adverse in-hospital outcomes in hospitalized surgical patients.

The nationwide German inpatient sample of the years 2005-2018 was used for this analysis. Surgical patients were stratified by AF and compared. Logistic regression models were used to investigate the impact of AF on in-hospital outcomes.

In total, 96,589,627 hospitalizations with surgery were included in the present analysis in Germany (2005-2018). Among these, 6,680,261 were additionally coded with AF (6.9%). In-hospital death rate was substantially higher in surgical patients with AF (6.3%) than without (1.1%). Proportion of surgical patients with AF increased from 4.8% in 2005 to 8.9% in 2018, whereas in-hospital mortality decreased from 7.6% to 5.6%. For further analysis of the year 2014, 7,043,514 hospitalized surgical patients (54.5% females, 31.6% aged ≥0years) were included in the analysis. Of these, 546,019 patients (7.8%) were diagnosed with AF. Overall, 1.4% of the surgical patients and 5.8% of the surgical patients with AF died in-hospital. Surgical patients with coded AF were in median 20years older (57.0 [37.0-72.0] vs. 77.0 [72.0-83.0] years, P<0.001), had more often comorbidities such as heart failure (31.3% vs. 3.8%, P<0.001). All-cause death (RR 6.14 (95%CI 6.05-6.22), P<0.001) occurred more often in patients with AF than without. AF was an important predictor for in-hospital death (OR 1.58 [95%CI 1.56-1.61], P<0.001) independent of age, sex and comorbidities.

The proportion of AF increased from 2005 to 2018 in surgical patients. AF was an independent risk factor for in-hospital death in these patients.

This complex process denominated syncytialization is fundamental for a correct pregnancy outcome. We observed that the endocannabinoid anandamide disrupts syncytialization employing traditional techniques and flow cytometry in BeWo cell line.

Though a large number of pregnant females have been affected by COVID-19, there is a dearth of information on the effects of SARS-CoV-2 infection on trophoblast function. We explored in silico, the potential interactions between SARS-CoV-2 proteins and proteins involved in the key functions of placenta.

Human proteins interacting with SARS-CoV-2 proteins were identified by Gordon et al. (2020). Genes that are upregulated in trophoblast sub-types and stages were obtained by gene-expression data from NCBI-GEO and by text-mining. Genes altered in pathological states like pre-eclampsia and gestational diabetes mellitus were also identified. Genes crucial in placental functions thus identified were compared to the SARS-CoV-2 interactome for overlaps. Proteins recurring across multiple study scenarios were analyzed using text mining and network analysis for their biological functions.

The entry receptors for SARS-CoV-2 - ACE2 and TMPRSS2 are expressed in placenta. Other proteins that interact with SARS-CoV-2 like LOX, Fibulins-2 and 5, NUP98, GDF15, RBX1, CUL3, HMOX1, PLAT, MFGE8, and MRPs are vital in placental functions like trophoblast invasion and migration, syncytium formation, differentiation, and implantation. TLE3, expressed across first trimester placental tissues and cell lines, is involved in formation of placental vasculature, and is important in SARS-CoV (2003) budding and exit from the cells by COPI vesicles.

SARS-CoV-2 can potentially interact with proteins having crucial roles in the placental function. Whether these potential interactions identified in silico have effects on trophoblast functions in biological settings needs to be addressed by further in vitro and clinical studies.
