Structurally and electronically driven uniaxial negative thermal expansion in BaIrO.

Negative thermal expansion is known to exist in a range of structure types but is extremely rare in hexagonal perovskites. Here we demonstrate that BaIrO displays negative linear thermal expansion in the direction of its face-shared IrO trimers, and apparent zero volume thermal expansion below 100 K. We present evidence that this anomalous thermal expansion is driven by an unusual form of rigid body phonon behaviour governed by the effective trimer valence state and therefore has structural and electronic components to the underlying mechanism.

Abdominal POCUS Education for Clinicians: A Systematic Review of Teaching Methods for Point-of-Care Abdominal Ultrasonography.

This systematic review examines educational strategies in clinician-performed abdominal point-of-care ultrasound (POCUS), a critical skill with increasing relevance in medical care. Analyzing 28 studies, we highlight the strategies as well as advantages and disadvantages of various theoretical and practical components, including, for example, e-learning and simulation in training programs. The findings emphasize the necessity of blending various educational methods to enhance effectiveness and adaptability in training environments.

Autoimmune Pancreatitis Masquerading as Pancreatic Cancer: A Case Report and Literature Review.

Autoimmune pancreatitis (AIP) is a chronic fibro-inflammatory disease of the pancreas that belongs to the spectrum of immunoglobulin G-subclass 4-related diseases (IgG4-RD). It is sometimes associated with a visible pancreatic mass mimicking pancreatic cancer on imaging. The most common presentations include abdominal pain and obstructive jaundice in elderly men.

Orbital Molecules in the New Spinel GaVO.

The structures and properties of vanadium oxides are often related to the formation of molecule-like clusters of vanadium cations through direct V-V bonding. GaVO, a new vanadium spinel, was synthesized. Powder diffraction and X-ray total scattering studies, complemented by magnetization and resistivity measurements, reveal that the low-temperature phase of this material is structurally distorted and features ordered pairs of three- and four-atom vanadium clusters.

Fecal Transplant in Inflammatory Bowel Disease.

Patients with inflammatory bowel disease (IBD) have differences in their gastrointestinal microbiome compared with healthy individuals, although it is unclear whether this is a cause or consequence of chronic inflammation. There is hope that manipulation of the gut microbiome through fecal microbiota transplant (FMT), commonly used to treat patients with Clostridium difficile infection, may also be an effective therapy in IBD. This article reviews the evidence supporting FMT in IBD, including case reports, case series, and randomized controlled trials.

A lack of anaesthetic clinical attachments for emergency medicine advanced trainees in New Zealand: perceptions of directors of emergency medicine training.

Aims: Anaesthetic skills are a core competency for emergency physicians. Anecdotally, there are limited anaesthetic attachments specifically available for Emergency Medicine Advanced Trainees (ATs). This study had several aims: Firstly, to quantify anaesthetic terms set aside for ATs; secondly, to gauge the opinions of Directors of Emergency Medicine Training (DEMTs) regarding the importance and difficulty in securing and maintaining anaesthetic training terms for ATs in their institutions; thirdly, to outline strategies that DEMTs used to get or maintain these posts and their opinions about what institutions should do to provide anaesthetic training for ATs.

Species-specific PCR to describe local-scale distributions of four cryptic species in the complex.

is a ubiquitous airborne fungus detected in every sampled region of the Earth. Owing to its role in Alexander Fleming's serendipitous discovery of Penicillin in 1928, the fungus has generated widespread scientific interest; however its natural history is not well understood. Research has demonstrated speciation within .

Lung abscess: update on microbiology and management.

A lung abscess is a circumscribed collection of pus in the lung as a result of a microbial infection, which leads to cavity formation and often a radiographic finding of an air fluid level. Patients with lung abscesses commonly present to their primary care physician or to the emergency department with "nonresolving pneumonia." Although, the incidence of lung abscess has declined since the introduction of antibiotic treatment, it still carries a mortality of up to 10%-20%.

Intravenous lipid emulsion does not augment blood pressure recovery in a rabbit model of metoprolol toxicity.

Intravenous lipid emulsion (ILE) has been demonstrated to be an effective treatment for systemic toxicity associated with local anaesthetics and increasingly non-local anaesthetic agents of high lipophilicity. Effect for ILE has been demonstrated in animal models of propranolol poisoning; however, any benefit for ILE in more hydrophilic β-blockers remains uncertain. We determined to examine the effect of ILE on haemodynamic recovery following induction of hypotension with the relatively hydrophilic β-blocker, metoprolol.
