Background: In patients with post-thrombotic syndrome (PTS), stent recanalization of iliofemoral veins or the inferior vena cava can restore venous patency and improve functional outcomes. The risk of stent thrombosis is particularly increased during the first 6 months after intervention. The ARIVA trial tested whether daily aspirin 100 mg plus rivaroxaban 20 mg is superior to rivaroxaban 20 mg alone to prevent stent thrombosis within 6 months after stent placement for PTS.

What Next for the Science of Patient Preference? Interoperability, Standardization, and Transferability.

Using patient preference information (PPI) to incorporate patient voices into the drug development lifecycle can help align therapies with the needs and values of patients. However, several barriers have limited the use of PPI, including a lack of clarity on its use by decision-makers, a need for greater decision-maker trust in PPI, and a lack of time, budgets, and access to specialist expertise. The value proposition for PPI could be enhanced by making it FAIR: Findable, Accessible, Interoperable, and Reusable.

Assessing Preferences of Patients with Chronic Spontaneous Urticaria for Injectable Treatment Profiles.

Background: In the context of injectable biologic products approved or in development for chronic spontaneous urticaria (CSU), it is important to capture which treatment attributes matter most to patient and what trade-offs patients are willing to make.

Objectives: The CHOICE-CSU study aimed to quantify patient preferences toward injectable treatment attributes among patients with CSU, inadequately controlled by H1-antihistamines.

Methods: This was a two-phase cross-sectional patient preference study in adult patients with a diagnosis of CSU, inadequately controlled by H1-antihistamines.

MR imaging of proton beam-induced oxygen depletion.

Background: Previous studies have shown that in-beam magnetic resonance imaging (MRI) can be used to visualize a proton beam during the irradiation of liquid-filled phantoms. The beam energy- and current-dependent local image contrast observed in water was identified to be predominantly caused by beam-induced buoyant convection and associated flow effects. Besides this flow dependency, the MR signal change was found to be characterized by a change in the relaxation time of water, hinting at a radiochemical contribution, which was hypothesized to lie in oxygen depletion-evoked relaxation time lengthening.

Pharmacoinformatics-based screening and construction of a neutralizing anti-SARS-CoV-2 camelidae nanobody drug conjugate.

Nanobodies or variable antigen-binding domains (VH) derived from heavy chain-only antibodies (HcAb) occurring in the Camelidae family offer certain superior physicochemical characteristics like enhanced stability, solubility, and low immunogenicity compared to conventional antibodies. Their efficient antigen-binding capabilities make them a preferred choice for next-generation small biologics. In the present work, we design an anti-SARS-CoV-2 bi-paratopic nanobody drug conjugate by screening a nanobody database.

Pelvic ring fracture and erectile dysfunction (PERFECD) - 3 year follow-up cross sectional study.

Introduction: Pelvic ring fractures are known to be associated with complications associated with adjacent organ injuries, such as the urogenital tract (e.g. erectile dysfunction (ED), which are sometimes diagnosed in a delayed fashion.

[HEW score-a tool for the homogenisation of donor registrations to the DSO : Multicentre retrospective analysis of three university hospitals].

Background: The persistently low number of postmortem organ donations in Germany has repeatedly led to political discussions and most recently to the amendment of the Transplantation Act with the strengthening of the role of the transplantation officer and the introduction of a register to document the will to donate. The background to these decisions was the assumption that a relevant proportion of potential organ donors in hospitals were being overlooked and not reported. However, due to the lack of guidelines as to when a potential organ donor must be reported to the DSO ("Deutsche Stiftung Organspende"), the existing data is only of limited validity.
