Exploring CT pixel and voxel size effect on anatomic modeling in mandibular reconstruction.

Background: Computer-aided modeling and design (CAM/CAD) of patient anatomy from computed tomography (CT) imaging and 3D printing technology enable the creation of tangible, patient-specific anatomic models that can be used for surgical guidance. These models have been associated with better patient outcomes; however, a lack of CT imaging guidelines risks the capture of unsuitable imaging for patient-specific modeling. This study aims to investigate how CT image pixel size (X-Y) and slice thickness (Z) impact the accuracy of mandibular models.

Understanding referral of patients with cancer in rural Ethiopia: a qualitative study.

Impact of obesity on adult spinal deformity (ASD) long-segment spinal fusion radiographic and clinical outcomes.

Study Design: Retrospective chart review of patients receiving long-segment fusion during a five-year period.

Objective: To determine whether obese patients receive comparable benefits when receiving long-segment fusion compared to non-obese patients and to identify factors that may predict hardware failure and post-surgical complications among obese patients.

Methods: Demographic, spinopelvic radiographic, patient-reported outcome measures (PROMs), and complications data was retrospectively collected from 120 patients who underwent long-segment fusion during a five-year period at one tertiary care medical center.

The infundibulochiasmatic angle and the favorability of an endoscopic endonasal approach in type IV craniopharyngioma: illustrative case.

Background: Lesions located in the floor of the third ventricle are among the most difficult to access in neurosurgery. The neurovascular structures can limit transcranial exposure, whereas tumor extension into the third ventricle can limit visualization and access. The midline transsphenoidal route is an alternative approach to tumor invading the third ventricle if the tumor is localized at its anterior half and a working space between the optic apparatus and the pituitary infundibulum exists.

Retention and turnover intention of foreign-trained physicians (FTPs): A scoping review.

Background: In many high-income countries, there is a regional or indication-specific shortage of physicians. One way to alleviate these shortages is to recruit physicians from abroad. However, the high turnover rate of foreign-trained physicians (FTPs) makes it difficult to maintain stable medical care.

A Modular Cloning Toolkit Including CRISPRi for the Engineering of the Human Fungal Pathogen and Biotechnology Host .

The yeast is an emerging, often drug-resistant opportunistic human pathogen that can cause severe systemic infections in immunocompromised individuals. At the same time, it is a valuable biotechnology host that naturally accumulates high levels of pyruvate─a valuable chemical precursor. Tools for the facile engineering of this yeast could greatly accelerate studies on its pathogenicity and its optimization for biotechnology.

Predicting non-response in patient-reported outcome measures: results from the Swiss quality assurance programme in cardiac inpatient rehabilitation.

Background: Quality assurance programmes measure and compare certain health outcomes to ensure high-quality care in the health-care sector. The outcome of health-related quality of life is typically measured by patient-reported outcome measures (PROMs). However, certain patient groups are less likely to respond to PROMs than others.

Cinefluoroscopy for assessment of mechanical heart valves with suspected dysfunction.

Background: Mechanical heart valves (MHVs) are preferred prosthesis types in many, especially younger patients who need surgical valve replacement. Although echocardiography is most frequently performed for prosthesis assessment during follow-up, ultrasound artifacts usually preclude a precise investigation of prosthesis function. Cinefluoroscopy (CF) is a simple and effective method to analyze and quantify opening and closing of prosthesis leaflets but requires careful visualization of the valve using optimal viewing angles.

Signatures of Exciton Orbits in Quantum Mechanical Recurrence Spectra of Cu_{2}O.

The seminal work by Kazimierczuk et al. [Nature 514, 343 (2014)10.1038/nature13832] has shown the existence of highly excited exciton states in a regime, where the correspondence principle is applicable and quantum mechanics turns into classical mechanics; however, any interpretation of exciton spectra based on a classical approach to excitons is still missing.

On the stability of thoriated tungsten cathodes in strong magnetic fields.

Thoriated tungsten cathodes, first studied by Langmuir [Phys. Rev. 22, 357-398 (1923)], are used in many applications as efficient electron emitters.

Neural and behavioural responses of the pollen-specialist bee Andrena vaga to Salix odours.

An effective means of finding food is crucial for organisms. Whereas specialized animals select a small number of potentially available food sources, generalists use a broader range. Specialist (oligolectic) bees forage on a small range of flowering plants for pollen and use primarily olfactory and visual cues to locate their host flowers.

Parental Misattribution of Environmental Stress Reaction Symptoms to Autism.

Objective: This research aims to characterize parental misattribution to autism of challenging child behaviors related to environmental stress.

Methods: To identify differences between parental concern about behavioral challenges and child diagnoses, researchers reviewed records of children assessed at a child development clinic (N = 50, mean age = 4.38), genetics clinic (N = 26, mean age = 4.

Structural Determination of an Unusual Cu -Porphyrin-π-Bond in a Hetero-Pacman Cu-Zn-Complex.

The synthesis and characterization of a hetero-dinuclear compound is presented, in which a copper(I) trishistidine type coordination unit is positioned directly above a zinc porphyrin unit. The close distance between the two coordination fragments is secured by a rigid xanthene backbone, and a unique (intramolecular) copper porphyrin-π-bond was determined for the first time in the molecular structure. This structural motif was further analyzed by temperature-dependent NMR studies: In solution at room temperature the coordinative bond fluctuates, while it can be frozen at low temperatures.

Performance of new crystal cathode pressure gauges for long-pulse operation in the Wendelstein 7-X stellarator.

To improve the reliability of the ASDEX pressure gauges in the plasma vessel of the Wendelstein 7-X stellarator, nine of them were equipped with a LaB crystal electron emitter for the first time. These crystal cathode pressure gauges were operated during the last campaign in 2018 (operation phase 1.2b) with only 2 A heating current for over 40 h in a magnetic field of about 2.

Facile C=O Bond Splitting of Carbon Dioxide Induced by Metal-Ligand Cooperativity in a Phosphinine Iron(0) Complex.

New iron complexes [Cp*FeL] (1-σ and 1-π, Cp*=C Me ) containing the chelating phosphinine ligand 2-(2'-pyridyl)-4,6-diphenylphosphinine (L) have been prepared, and found to undergo facile reaction with CO under ambient conditions. The outcome of this reaction depends on the coordination mode of the versatile ligand L. Interaction of CO with the isomer 1-π, in which L binds to Fe through the phosphinine moiety in an η fashion, leads to the formation of 3-π, in which CO has undergone electrophilic addition to the phosphinine group.

Histopathology of Moyamoya angiopathy in a European patient.

Background And Purpose: Moyamoya angiopathy (MMA) is rare outside Asia. Little is known about pathophysiology in European patients. This study aims to elucidate the histopathology of non-Asian MMA and its similarities and differences to those cases from Asia.

Three-dimensional structure of antiphase domains in GaP on Si(0 0 1).

Antiphase domains are three-dimensional crystal defects commonly arising at the interface of III-V semiconductors and Si. While control over their formation has been achieved, the geometry of the antiphase domain itself that is separated from the mainphase of the crystal by the so-called antiphase boundary, has not yet been fully understood. In this work, we first investigate the interface between GaP and Si itself by cross-sectional scanning tunneling microscopy (XSTM) to reveal possible intermixing within an 8 monolayers wide region.
