Effects of a supercritical CO process on the mechanical properties and microarchitecture of trabecular bone using compression testing and microcomputed tomography.

Surgeons frequently use allograft bone due to its osteoconductive, osteoinductive, and osteogenic properties. Preservation processes are employed to clean the allograft, improve its conservation, and ensure its sterilization. Many current processes use the properties of supercritical CO to remove bone marrow.

Exploring the quality of end-of-life care in the intensive care unit: a qualitative multiple case study approach with family members of Muslim patients.

Objective: Muslim patients are an underrepresented community in end-of-life care research, with little evidence around factors that influence the quality and experience of care. The aim of this study was to explore the quality of end-of-life care in the intensive care unit (ICU) from the perspective of next-of-kin family members of Muslim patients.

Design: A qualitative multiple case study design using semistructured interviews with family members of Muslim patients.

Improving cefazolin administration for surgical prophylaxis in reported penicillin allergy: A retrospective study of a health system intervention.

Background: Cefazolin is the most common first-line antibiotic to prevent surgical-site infections. Patients with penicillin allergy labels often receive alternative antibiotics, which is associated with increased rates of surgical-site infections, multi-drug-resistant infections, and cost.

Objective: We sought to determine whether a hospital-wide guideline recommending first-line surgical prophylaxis in patients with penicillin allergy labels can increase the use of cefazolin without compromising safety.

Silicon Nanotube Anode on Copper Foils for Li-Ion Batteries.

We report a silicon anode for lithium-ion batteries consisting of a layer of 100% nanotubes directly bonded to copper foil. The process involved silicon deposition on a sacrificial zinc oxide nanorod film and removal of zinc oxide to produce a nanotube film directly on thin copper foils. The thickness of resulting films ranged from 9 to 20 μm with Si nanotubes having diameters of 200-400 nm and lengths of 2-10 μm.

Polygenic risk for depression and resting-state functional connectivity of subgenual anterior cingulate cortex in young adults.

Background: Genetic variants may confer risk for depression by modulating brain structure and function; evidence has underscored the key role of the subgenual anterior cingulate cortex (sgACC) in depression. We sought to examine how the resting-state functional connectivity (rsFC) of the sgACC was associated with polygenic risk for depression in a subclinical population.

Methods: Following published protocols, we computed seed-based whole-brain sgACC rsFC and calculated polygenic risk scores (PRS) using data from healthy young adults from the Human Connectome Project.

Short bouts and long-term exercise reduce sedentary-induced bone loss and microstructural changes by modulating bone formation and resorption in healthy young male rats.

Although the toxic effect of Sedentary behavior (SED) on bone health has been demonstrated in the previous study, the underlying mechanisms of SED, or break SED to bone health remain unclear. In this study, we aim to investigate the effects of sedentary behavior (SED) on bone health, as well as the potential favor effects of moderate to vigorous physical activity (MVPA) and periodic interruptions of SED. To simulate SED, we used small Plexiglas cages (20.

Microcomputed tomographic analysis of the trabecular and cortical architecture of the proximal femur and hip bone of cats and small breed dogs.

This study aims to provide an initial database to gain more detailed knowledge of the trabecular and cortical bone structure of pelvic and femur bones in cats and smaller dogs. Additionally, the bony microarchitecture between cats and smaller dogs was compared to identify possible differences between those species. These findings could potentially improve the development of non-cemented total hip replacement (THR).

Association between the proportionality of functional mitral regurgitation and survival after mitral valve operation.

Objective: The concept of proportionate and disproportionate functional mitral regurgitation suggests that transcatheter edge-to-edge mitral repair may benefit patients with a smaller left ventricle relative to a higher regurgitant burden. The clinical relevance of proportionality remains unknown in mitral operations for ischemic mitral regurgitation. We aimed to characterize the association between mitral regurgitation proportionality and outcomes after mitral valve operations.

Concomitant Potentially Contagious Factors Detected in Poland and Regarding Strains, Etiological Agents of Keratitis in Humans.

Background: Diseases in humans caused by amphizoic amoebae that can result in visual impairment and even blindness, have recently been identified more frequently worldwide. Etiologically complex incidents of keratitis, including those connected with strains detected in Poland, were evaluated in this study.

Methods: Corneal samples from cases resistant to antimicrobial therapy assessed for epidemiological, microbiological and parasitological aspects were investigated by phase-contrast microscope, slit lamp and by confocal microscopy.

Hypokalemia-Induced Rhabdomyolysis Secondary to Adrenal Adenoma: A Case Report.

Adrenal adenoma, which leads to increased production of the hormone aldosterone, commonly presents as hypertension and hypokalemia. Rhabdomyolysis as a result of hypokalemia secondary to primary hyperaldosteronism is a rare but important complication with only a few reported cases. Low potassium levels can disrupt the regulation of arteriolar musculature, leading to reduced blood flow to skeletal muscles.

Transient Ischaemic Attack in a Patient With Conn Syndrome: A Case Report and Literature Review on the Importance of Identifying Secondary Hypertension.

Background/aim: Transient ischaemic attack (TIA) is characterised by a temporary neurological dysfunction resulting from focal ischaemia in the brain, spinal cord or retina without acute infarction. These episodes typically last less than 24 hours and are significant predictors of subsequent ischaemic strokes. Hypertension is a major risk factor for cerebrovascular events, and primary aldosteronism (PA) is recognised as a common cause of secondary hypertension.

Multilayer network analysis in patients with end-stage kidney disease.

This study aimed to investigate alterations in a multilayer network combining structural and functional layers in patients with end-stage kidney disease (ESKD) compared with healthy controls. In all, 38 ESKD patients and 43 healthy participants were prospectively enrolled. They exhibited normal brain magnetic resonance imaging (MRI) without any structural lesions.

Improving diagnosis of primary aldosteronism through education: a modified Delphi study to identify key learning points.

Background: Primary aldosteronism (PA) is the most common endocrine cause of secondary hypertension and can be effectively managed, or even cured, with targeted treatment. Despite this, it remains largely undiagnosed leaving a significant patient population with resistant hypertension and modifiable cardiovascular risk.

Objective: To determine expert consensus on key information about PA that should ideally be taught to medical students as a step toward improving the detection of this common, underdiagnosed, and often easily treated condition.

A technique to enhance the gingival esthetics of a prototype complete arch fixed implant-supported prototype prosthesis using a 3D printed gingival veneer.

An important step in the workflow for a complete arch fixed implant-supported prosthesis is the fabrication of a prototype resin prosthesis to allow the patient to visualize the definitive treatment outcome and also to use as an interim prosthesis. Producing a prototype prosthesis with the natural appearance of the gingival color and contour has been challenging. Current methods include painted stains, manually applied pink composite resin or autopolymerizing acrylic resin, and multicolored resin blocks, but these are all relatively expensive, have less than optimal esthetics, and are labor-intensive and time-consuming.

Mild autonomous cortisol secretion leads to reduced volumetric BMD at lumbar spine in patients with primary aldosteronism.

Objectives: Glucocorticoid cosecretion is more common in primary aldosteronism (PA) than previously thought. Chronic subtle cortisol excess in patients with mild autonomous cortisol secretion (MACS) negatively affects bone health. This study aimed to evaluate the impact of MACS on bone density and turnover markers in PA patients.

Functional connectivity abnormalities in clinical variants of progressive supranuclear palsy.

Progressive supranuclear palsy (PSP) can present with different clinical variants which show distinct, but partially overlapping, patterns of neurodegeneration and tau deposition in a network of regions including cerebellar dentate, superior cerebellar peduncle, midbrain, thalamus, basal ganglia, and frontal lobe. We sought to determine whether disruptions in functional connectivity within this PSP network measured using resting-state functional MRI (rs-fMRI) differed between PSP-Richardson's syndrome (PSP-RS) and the cortical and subcortical clinical variants of PSP. Structural MRI and rs-fMRI scans were collected for 36 PSP-RS, 25 PSP-cortical and 34 PSP-subcortical participants who met the Movement Disorder Society PSP clinical criteria.

Discovery of 4-(5-Membered)Heteroarylether-6-methylpicolinamide Negative Allosteric Modulators of Metabotropic Glutamate Receptor Subtype 5.

This Letter details our efforts to develop novel, non-acetylene-containing metabotropic glutamate receptor subtype 5 (mGlu) negative allosteric modulators (NAMs) with improved pharmacological properties. This endeavor involved replacing the ether-linked pyrimidine moiety, a metabolic liability, with various 5-membered heterocycles. From this exercise, we identified , a highly brain penetrant and selective mGlu NAM which displayed moderate potency against both human and rat mGlu.
