Because of the inherent quasibrittleness and heterogeneity, matrix-directed toughening of concrete and cement composites remains to be a huge challenge. Herein, inspired by nacre materials, a novel biomimetic bulk cement composite is fabricated via a facile and efficient process based on compacting prefabricated multisized cement-polymer hybrid prills. This method combines with the three-dimensional "brick-bridge-mortar" structure design and synchronously the intrinsic and extrinsic toughening strategies. Such an approach shows the remarkable maximum toughness enhancement of 27-fold with 71% increase in flexural strength via cooperation with only 4 wt % organic matter. More attractively, it alters the traditional brittle fracture of cement composites to a distinct ductile fracture. In addition, such a biomimetic composite demonstrates the long-term ever-increasing strength and toughness, performing the excellent ductile-fracture retention ability. The hierarchical toughening mechanisms are further revealed with the synergy of microscopic characterizations and simulation methods. This strategy provides a new route for the development of high toughness biomimetic cement-based materials for potential applications in civil engineering domain.Magnetic skyrmions are nontrivial spin textures that resist external perturbations, being promising candidates for the next-generation recording devices. Nevertheless, a major challenge in realizing skyrmion-based devices is the stabilization of ordered arrays of these spin textures under ambient conditions and zero applied field. Here, we demonstrate for the first time the formation and stabilization of magnetic skyrmions on the arrays of self-assembled hexagonal nanodomes taking advantage of the intrinsic properties of its curved geometry. Magnetic force microscopy images from the arrays of 100 nm nanodomes showed stable skyrmions at the zero field that are arranged following the topography of the nanostructure. Micromagnetic simulations are compared to the experiments to determine the correlation of the domain textures with the topography of the samples. We propose a simple method to nucleate and annihilate skyrmions, opening the possibility for an ultradense data storage based on the high stability and low energy consumption of the skyrmionic textures.Solutions or sols are commonly employed as the starting materials for the preparation of supramolecular hydrogels; however, suspension-based synthesis has been much less reported because of inhomogeneity and quick sedimentation of large particles in a suspension. Further, it remains a technical challenge to derive supramolecular aerogels directly from the parental hydrogels owing to the ease of structural collapse during water removal. Herein, we report a suspension-gel transition for the ultrafast synthesis of a new supramolecular hydrogel simply by adding AgNO3 into the aqueous suspension of cyanuric acid-melamine (CAM) aggregates. With the activation of preadded ammonia, Ag ions instantly reacted with the CAM particles, transforming into N-Ag(I)-N coordinating bonded supramolecular nanofibers; simultaneously, the suspension converted to a hydrogel without the use of polymer cross-linkers or external stimulus. Upon simple freeze-drying, a highly crystalline fibrous aerogel with a cellular network was obtained, which possessed a porosity up to 99.7% and a density as low as 4.8 mg/cm3, enabling remarkable oil uptake capacities (100 times of its weight). The supramolecular aerogel demonstrated intrinsic elasticity, which should arise from the cellular structure and elastic character of the nanofiber skeletons. Notably, the aerogel showed high compatibility to incorporate a range of external substances for further functionalization exemplified by polymeric carbon nitride (PCN, a metal-free semiconductor) included gels. The loaded PCN resulted in enhanced mechanical strength and endowed the aerogel unique photoactivity, i.e., in situ reducing Ag(I) into Ag nanoparticles upon light illumination and thus forming a plasmonic shell over the aerogel with potential applications in sensing and catalysis.
This study aimed to demonstrate the application of our automated facial recognition system to measure facial nerve function and compare its effectiveness with other conventional systems and provide a preliminary evaluation of deep learning-facial grading systems.

Retrospective, observational.

Tertiary referral center, hospital.

Facial photos taken from 128 patients with facial paralysis and two persons with no history of facial palsy were analyzed.

Diagnostic.

Correlation with Sunnybrook (SB) and House-Brackmann (HB) grading scales.

Our results had good reliability and correlation with other grading systems (r = 0.905 and 0.783 for Sunnybrook and HB grading scales, respectively), while being less time-consuming than Sunnybrook grading scale.

Our objective method shows good correlation with both Sunnybrook and HB grading systems. Furthermore, this system could be developed into an application for use with a variety of electronic devices, including smartphones and tablets.

The aim was to model residual Vestibular Schwannoma (VS) over time to identify prognostic factors of postsurgical growth.

Multicenter retrospective study.

Tertiary referral centers.

A group of 135 patients who underwent incomplete resection for VS between January 2010 and December 2018. On magnetic resonance imaging (MRI) examinations at baseline (1 year after surgery), patients included were divided into two groups near-total resection (NTR, <25 mm × 2 mm) and subtotal resection (STR, greater volume).

Monitoring of residual VS volume.

3D volumetric segmentation of residual tumors was performed on every MRI examination at baseline and during follow-up to model volume changes over time using the Lambda-Mu-Sigma method.

The study followed-up 127 patients (median age 56 yr) over a median follow-up of 39 months. Most VS residues (76.7%; 89/116) showed no growth at 5 years. Only 27 (23.3%) residues showed signs of regrowth (increase in volume >0.05 cm). The extent of resection is a predictor of tumor growth (odds ratio [OR] = 4.85; for STR over NTR; p = 0.003), but the growth rate was significantly different between STR and NTR residues (p < 0.001). At first, over 2 years after surgery, STR residues decreased (-1.0% volume per year), whereas NTR ones grew (+8% per year). Then, both residues showed sign of regrowth.

Postoperative recommendations should now include the natural history of VS residue after resection even though the growth rate differs between STR and NTR residues, most VS residues showed no growth.

To coordinate and align the content for registration of cholesteatoma care.

Systematic Delphi consensus procedure, consisting three rounds two written sessions followed by a face-to-face meeting. Before this procedure, input on important patient outcomes was obtained. Consensus was defined as at least 80% agreement by participants. Hundred-thirty-six adult patients who had undergone cholesteatoma surgery and all ENT surgeons of the Dutch ENT Society were invited. The consensus rounds were attended by ENT surgeons with cholesteatoma surgery experience. Feasibility and acceptability of outcome measures and reporting agreements were assessed in round 1 by 150 ENT surgeons. In round 2 definitions were narrowed and context information to interpret outcome measure were questioned. In round 3, the results, amendments, and the open-ended points were discussed to reach agreement.

Most important outcome measures are 1) the presence or absence of a cholesteatoma in the first 5 years after surgical removal of choleare.
To construct an early health economic model to assess the potential added value of novel hearing therapeutics, compared with the current standard of care. We use idiopathic sudden sensorineural hearing loss (ISSNHL) as a case example, because it is a lead indication for several emerging hearing therapeutics.

A decision analytic model was developed to assess the costs and effects of using novel hearing therapeutics for patients with ISSNHL. This was compared to the current standard of care. Input data were derived from literature searches and expert opinion. The study adopted a healthcare perspective of the UK National Health Service. Four analyses were conducted 1) headroom, 2) scenario, 3) threshold, 4) sensitivity.

The decision analytic model showed that novel therapeutics for ISSNHL have potential value both in terms of improved patient outcomes, as well as incremental net monetary benefit (iNMB). The base case analysis revealed an iNMB of £39,032 for novel therapeutics compared with the current stancs represent value for money.
To assess differences in hearing disabilities between different age groups and the effectiveness of rehabilitation with hearing aids.

Retrospective chart review.

First line hearing aid dispensers.

First-time hearing aid users divided in a younger group aged 18 to 65 years (119 subjects) and an elderly group aged 70 years and older (213 subjects).

Rehabilitative.

Weighted pure tone averages (PTA) were calculated using the binaural impairment model. The patient-reported outcome measures (PROMs) Amsterdam Questionnaire for Auditory Disabilities (AVAB), and client oriented scale of improvement (COSI) were collected pre- and post-fitting. To analyze whether age group, weighted PTA, and type of auditory dimension influences AVAB, linear regression and two-way ANalysis Of VAriance models were used.

The weighted PTA of the young group was significantly lower than of the elderly group. In the regression model differences between age groups were found to be significant for pre-AVAB and for AVAB benefit. The two-way ANalysis Of VAriance showed that the effect of age on pre- and post-AVAB scores was not influenced by PTA or the type of auditory dimension.

Younger first-time hearing aid users experience more auditory disabilities, despite better hearing levels than their elderly counterparts. Their disabilities are rehabilitated more effectively by hearing aids.

To perform a systematic review and meta-analysis of surgical outcomes following repair of patulous Eustachian tube (PET).

Analysis of cases collected from studies published between January 1990 and December 2018 and identified using PubMed, Google Scholar, and Cochrane databases.

Articles addressing interventions to treat PET were selected.

The database was searched using the keywords "patulous Eustachian tube treatment" and yielded 1,370 studies. Twenty studies were eligible for inclusion.

A total of 914 cases were evaluated for surgical approach, patient outcomes, and complications. The reported techniques were categorized by the procedure type, including ventilation tube insertion, mass loading of the tympanic membrane, ET injection, plug surgery, shim surgery, tuboplasty, and ET closure. Overall PET symptom improvement were reported for ventilation tube insertion (79 cases, mean 58%, 95% CI 47-69%), mass loading of the tympanic membrane (43 cases, mean 50%, 95% CI 32-69%), ET injection (139 cases, mean 47%, 95% CI 38-56%), plug surgery (386 cases, mean 81%, 95% CI 77-85%), shim surgery (122 cases, mean 62%, 95% CI 53-70%), tuboplasty (105 cases, mean 41%, 95% CI 31-51%), and ET closure (40 cases, mean 66%, 95% CI 49-80%).
