The effect of romosozumab on bone mineral density depending on prior treatment: a prospective, multicentre cohort study in Switzerland.

Unlabelled: This multicentre, prospective cohort study measured the effect of romosozumab for 12 months on bone mineral density, taking into account prior therapies. Prior antiresorptive therapy blunted the BMD response to romosozumab, and the duration was correlated with BMD changes at both the lumbar spine and total hip.

Introduction: In Switzerland, romosozumab is administered to high-risk osteoporosis patients.

Host guest chemistry and supramolecular doping in triphenylamine-based covalent frameworks on Au(111).

The post-synthetic modification of covalent organic frameworks (COFs) via host-guest chemistry is an important method to tailor their electronic properties for applications. Due to the limited structural control in the assembly of two-dimensional surface-supported COFs, supramolecular networks are traditionally used at present for host-guest experiments on surfaces, which lack structural and thermal stability, however. Here, we present a combined scanning tunneling microscopy and density functional theory study to understand the host-guest interaction in triphenylamine-based covalently-linked macrocycles and networks on Au(111).

Binary supramolecular networks of bridged triphenylamines with different substituents and identical scaffolds.

Based on scanning tunneling microscopy experiments combined with density functional theory, we report the formation and the electronic structure of porous binary supramolecular networks on Au(111). The two triphenylamine derivatives with identical scaffolds intermix due to a maximization of the overall number of H-bonds instead of an optimization of the H-bond strength in the bonding motif. The HOMO-LUMO gap is defined by both molecules, which is typical for electron donor-acceptor networks.

Hierarchical on-surface synthesis and electronic structure of carbonyl-functionalized one- and two-dimensional covalent nanoarchitectures.

The fabrication of nanostructures in a bottom-up approach from specific molecular precursors offers the opportunity to create tailored materials for applications in nanoelectronics. However, the formation of defect-free two-dimensional (2D) covalent networks remains a challenge, which makes it difficult to unveil their electronic structure. Here we report on the hierarchical on-surface synthesis of nearly defect-free 2D covalent architectures with carbonyl-functionalized pores on Au(111), which is investigated by low-temperature scanning tunnelling microscopy in combination with density functional theory calculations.

Optically pure, monodisperse cis-oligodiacetylenes: aggregation- induced chirality enhancement.

Conformational changes in the conjugated backbone of poly- and oligodiacetylenes (PDAs and ODAs) play an important role in determining the electronic properties of these compounds. At the same time, conformational changes can also result in a folded structure that shows helical chirality. Using d-camphor as a chiral building block, we have designed a high-yielding, iterative synthesis of monodisperse, optically pure cis-oligodiacetylenes (ODAs).

Management of Morel-Lavallee Lesion Associated with Pelvic and/or Acetabular Fractures.

Objective: Management of Morel-Lavallee soft tissue lesion (MLL) in patients with associated pelvic and/or acetabular fractures is still under discussion. Especially, the sequence of treatment of MLL soft tissue management and osteosynthesis of pelvic and acetabular injury remains controversial.

Methods: We report all consecutive patients with MLL associated with pelvic ring and/or acetabular fractures during an 8-year period at our hospital.

Binding of bilirubin and bromosulphthalein to albumin: implications for understanding the pathophysiology of liver failure and its management.

The binding/transporting functions of albumin provide the rationale for using albumin dialysis (e.g., molecular adsorbents recirculating system [MARS]) in liver failure.

Equipment review: the molecular adsorbents recirculating system (MARS).

The molecular adsorbents recirculating system (MARS) is a form of artificial liver support that has the potential to remove substantial quantities of albumin-bound toxins that have been postulated to contribute to the pathogenesis of liver cell damage, haemodynamic instability and multi-organ failure in patients with acute liver failure (ALF) and acute-on-chronic liver failure (AoCLF). These toxins include fatty acids, bile acids, tryptophan, bilirubin, aromatic amino acids and nitric oxide. Data from controlled clinical trials are limited so far.

Extracorporeal liver support with molecular adsorbents recirculating system in patients with severe acute alcoholic hepatitis.

Background/aims: The mortality of patients with severe acute alcoholic hepatitis (AH) remains high, leading to interest in the use of extracorporeal liver support. The molecular adsorbents recirculating system (MARS) is a liver support device based upon a hollow fibre module in which the patient's blood is dialyzed across an albumin-impregnated membrane. The aim of this paper is to assess the safety, efficacy and feasibility of using MARS in patients with severe AH.

Albumin dialysis and Molecular Adsorbents Recirculating System (MARS) for acute Wilson's disease.

Wilson's disease presenting as acute liver failure (ALF) is potentially fatal, and liver transplantation (LTx) is the only option. We report two patients with Wilson's disease and ALF treated with the Molecular Adsorbents Recirculating System (MARS). Both patients fulfilled criteria for poor prognosis.

Experiences with MARS liver support therapy in liver failure: analysis of 176 patients of the International MARS Registry.

Extracorporeal liver support using the MARS recently has shown remarkable results in several trials. This study aims to extend the basis for analyses by making available the worldwide data with help of an international registry. One hundred and seventy six patients were analysed, main indications are acute-on-chronic liver failure (56%), acute liver failure (22%), primary graft dysfunction (15%), liver failure post liver surgery (4%) and miscellaneous (3%).

Clinical outcome of edema-like bone marrow abnormalities of the foot.

Purpose: To evaluate the clinical outcome of edema-like bone marrow abnormalities seen on magnetic resonance (MR) images of the foot when their cause is unknown.

Materials And Methods: The clinical outcome of 31 patients (15 female patients, 16 male patients; mean age, 51; range, 10-79 years) with edema-like bone marrow abnormalities on MR images of the foot was determined. The relevance of three different edema patterns was compared: (a) exclusively ill-defined edema-like zones, (b) edema-like zones plus well-defined necrosis-like zones, and (c) edema-like zones plus linear structures indicating possible fractures.
