Sensitivity analysis of the controlled system shows a delay tolerance of 300ms. Preliminary empirical data in support of the mathematical model were obtained from perturbation experiments. The model response to perturbation torque, measured in terms of the center of mass (COM) excursion in the anterior-posterior (AP) direction, displays a high degree of correlation with the empirical data ([Formula see text]).Until July 31, 2020, about 17.6 million SARS-CoV‑2 infections and 680,000 deaths from COVID-19 were reported. SARS-CoV‑2 is most likely transmitted by droplets and probably by aerosols. Patients become infectious 2-3 days before the onset of symptoms, and persons with asymptomatic infections are also infectious. COVID-19 affects the upper respiratory tract, lungs (pneumonia, acute respiratory distress syndrome [ARDS]), heart, liver, gastrointestinal tract, and other organs. SARS-CoV‑2 uses ACE2 a receptor to enter host cells. Vasculitis, endothelial damage, thromboembolic events and organ failure are accompanied by a massive cytokine response. check details Elderly people and those with pre-existing diseases are particularly vulnerable. An efficient antiviral therapy is not yet available. Severely ill patients may benefit from dexamethasone and early treatment of complications. Candidate vaccines are currently being tested in clinical studies.In general, the removal of peripherally inserted central venous catheters (PICC) in neonates by gentle traction is easy. In our case, the removal of a 28G PICC in a term neonate was impossible by manual traction even with force. Previously described non-invasive interventions using a stylet were not successful because it was not possible to pass the stylet along the catheter hub of the narrow 28G PICC. In the end, the catheter could be removed non-operatively by cutting the catheter just distal to the hub and inserting a stylet of a new PICC (same brand and size) into the patients' retained catheter. Subsequently, the force of manual traction on the catheter could be increased without increased risk of catheter stretching and breakage. After catheter removal, the surface of the remaining PICC was intact.Conclusion By thinking outside the box, surgical intervention was prevented in this neonate. What is Known • On general, peripherally inserted central venous catheters (PICC) can be removed easily by gentle traction. • There are no clear recommendations about what to do if standard interventions fail to remove a PICC. What is New • Our technique is a non-invasive option for difficult PICC removal and can prevent surgery. • The retained PICC is cut distal to the hub, and after stylet reinsertion, sustained manual traction is performed.
Occlusion or significant stenosis of the internal carotid artery (ICA) in the cervical segment is commonly associated with apoststenotic decrease in the downstream blood flow and perfusion. Fluid attenuated inversion recovery (FLAIR) vascular hyperintensities (FVH) are aphenomenon that represents slow arterial blood flow. In this study, we investigated the frequency and extent of FVH in the distal ICA in patients with proximal ICA stenosis.
We analyzed the magnetic resonance imaging (MRI) findings in 51patients with atotal of 60cervical ICA stenoses with special focus on the frequency and extent of FVH in the area of the petrous segment of the ICA on FLAIR images and correlated these with Doppler/duplex sonography results.
In 46(76.7%) patients with ICA stenosis, FVH could be detected in the petrous segment of the ICA in 19(41.3%) patients athin hyperintense rim near the vessel wall (grade1), in 24(52.2%) patients astrong hyperintense rim near the vessel wall (grade2), and in 3(6.5%) patients ahyperintense filling of the entire lumen (grade3) was observed. The extent of FVH in the ICA in the petrous segment showed a high negative correlation with the poststenotic flow velocity (Spearman correlation, R = -0.75, p < 0.001), and moderate correlation with the degree of ICA stenosis (Spearman correlation, R = 0.51, p< 0.001).
An FVH in the petrous ICA is commonly seen among patients with steno-occlusive disease in proximal ICA and could therefore be useful to recognize aproximal ICA stenosis even on FLAIR images.

Liraglutide, a daily injectable glucagon-like peptide-1 receptor (GLP-1r) agonist, has been shown to reduce liver fat content (LFC) in humans. Data regarding the effect of dulaglutide, a once-weekly GLP-1r agonist, on human LFC are scarce. This study examined the effect of dulaglutide on LFC in individuals with type 2 diabetes and non-alcoholic fatty liver disease (NAFLD).
Effect of dulaglutide on liver fat (D-LIFT) was a 24week, open-label, parallel-group, randomised controlled trial to determine the effect of dulaglutide on liver fat at a tertiary care centre in India. Adults (n = 64), who had type 2 diabetes and MRI-derived proton density fat fraction-assessed LFC of ≥6.0% at baseline, were randomly assigned to receive dulaglutide weekly for 24weeks (add-on to usual care) or usual care, based on a predefined computer-generated number with a 11 allocation that was concealed using serially numbered, opaque, sealed envelopes. The primary endpoint was the difference of the change in LFC from 0 (baseline) tarch fund and a grant from the Endocrine and Diabetes Foundation (EDF), India. Graphical abstract.
Anatomic reduction in tibial plateau fractures remains to be demanding. For further visualisation of and approach to the joint surface an extended lateral approach using a lateral femoral epicondyle osteotomy and subluxation of the lateral meniscus was recently described. First clinical and radiographic mid-term results of this technique are presented in this feasibility study.
Ten complex tibial plateau fractures treated with extended lateral approach and lateral meniscal subluxation were prospectively analysed. Clinical and radiographic results were objectified according to the Rasmussen scores.
After a median follow-up of 8.6 (IQR 4.3) months good to excellent clinical and radiographic results were noted. The clinical Rasmussen Score showed a median of 25 (IQR 2.8) and radiographic a median of 17 (IQR 2.0) points.
Good to excellent clinical and radiological scores were obtained after using an extended lateral approach with lateral femoral epicondyle osteotomy and central meniscus subluxation. No approach specific complications could be observed.
