The arthritis connection to inflammatory bowel disease (IBD): why has it taken so long to understand it?

RMD Open 2021 Apr;7(1)

Internal Medicine, Stanford University School of Medicine, Stanford, California, USA

Inflammatory bowel disease (IBD) associated arthritis is a subgroup of spondyloarthritis (SpA) that has suffered from lack of recognition in rheumatology clinical and research circles for over 100 years. Although clinically distinguishable from rheumatoid arthritis and ankylosing spondylitis, it took advances in detection systems in the middle of the last century (rheumatoid factor, HLA-B27) to convincingly make the final separations. We now know that significant numbers of patients with SpA have associated clinical IBD and almost half of them show subclinical gut inflammation, yet the connection between the gut and the musculoskeletal system has remained a vexing problem.

Magnetic Anisotropy in a Cubane-like Ni Complex: An Ab Initio Perspective.

Authors:
Rémi Maurice

Inorg Chem 2021 Apr 16. Epub 2021 Apr 16.

SUBATECH, UMR CNRS 6457, IN2P3/IMT Atlantique/Université de Nantes, 4 rue A. Kastler, 44307 Nantes Cedex 3, France.

Magnetic anisotropy, in the absence of an external magnetic field, relates to the degeneracy lift of energy levels. In the standard case of transition metal complexes, this property is usually modeled by an anisotropic spin Hamiltonian and one speaks of "zero-field splitting" (ZFS) of spin states. While the case of mononuclear complexes has been extensively described by means of ab initio quantum mechanical calculations, the literature on polynuclear complexes studied with these methodologies is rather scarce.

Making sense of senseless murders: The who, what, when, and where?

Behav Sci Law 2021 Apr 16. Epub 2021 Apr 16.

Royal Canadian Mounted Police, Burnaby, British Columbia, Canada.

The phenomenon of "senseless" or "motiveless" homicide refers to homicides that lack an objective external motivation. Despite the unique challenges these homicides pose to police, few empirical studies have been conducted on the topic and existing studies are limited to clinical studies using small samples. To overcome existing empirical shortcomings, the current study used a sample of 319 homicide cases where no motive was established during the investigation to describe the "who" (offender and victim characteristics), "what" (modus operandi, crime characteristics), "where" (encounter, crime, and body recovery associated locations), and "when" (time of the crime) of the entire criminal event.

The effects of ACE2 expression mediating pharmacotherapy in COVID-19 patients.

Neth Heart J 2021 Apr 16. Epub 2021 Apr 16.

Department of Experimental Cardiology, Amsterdam University Medical Center, Amsterdam, The Netherlands.

Background: There has been debate on the use of angiotensin-converting enzyme‑2 (ACE2) expression mediating pharmacotherapy in COVID-19 infected patients. Although it has been suggested that these drugs might lead to a higher susceptibility and severity of COVID-19 infection, experimental data suggest these agents may reduce acute lung injury via blocking angiotensin-II-mediated pulmonary permeability, inflammation and fibrosis.

Methods: A systematic literature search was performed to answer the question: What is the effect of medications that influence ACE2 expression (ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), nonsteroidal anti-inflammatory drugs (NSAIDs) and thiazolidinediones) on the outcomes of COVID-19? Relevant outcome measures were mortality (crucial), hospital admission, length of stay, thromboembolic complications (pulmonary embolism, stroke, transient ischaemic attack), need for mechanical ventilation, acute kidney injury and use of renal replacement therapy.

Consistency in Motion Event Encoding Across Languages.

Front Psychol 2021 30;12:625153. Epub 2021 Mar 30.

Department of Linguistics, Stockholm University, Stockholm, Sweden.

Syntactic templates serve as schemas, allowing speakers to describe complex events in a systematic fashion. Motion events have long served as a prime example of how different languages favor different syntactic frames, in turn biasing their speakers toward different event conceptualizations. However, there is also variability in how motion events are syntactically framed within languages. Read More
