Maurizio Aceto, Elisa Calà
Iron-gall ink (IGI) has been used by scribes for writing since at least the 4th century CE. Another typical use of this ink was for drawing: many Old Masters created beautiful sketches in brown-black hues. Despite its widespread use to draw lines, it seems like IGI was hardly used for painting as well. In fact, the number of identification on manuscripts is very low at present. This could be partially due to a lack of reliable diagnostic information. In this work we tried to better define the possibility of identifying IGI as a pigment on illuminate manuscripts, evaluating the pros and cons of three different techniques: UV-visible diffuse reflectance spectrophotometry with optic fibres (FORS), Raman spectroscopy and XRF spectrometry...

BACKGROUND: Acne fulminans (AF) is a severe variant of inflammatory acne. It typically manifests as an explosive worsening and ulceration of skin lesions, and can be associated with systemic symptoms. However, there is a paucity of evidence-based information and no clear guidelines concerning the classification and treatment of AF. OBJECTIVE: To better define the spectrum of AF and its variants, devise optimal therapeutic approaches, and identify areas of future research...

OBJECTIVE: We aimed to evaluate patient perceptions of medical scribes in the ED and to test for scribe impacts on ED Net Promoter Scores, Press Ganey Surveys and other patient-centred topics. METHODS: Exploratory semi-structured interviews were conducted in the ED during wait times after scribed consultations. Interview results were used to derive topics relating to scribes. Items addressing these topics from validated surveys were combined with items from widely used patient satisfaction questionnaires...

The local efficiency of lamellar shaped Cu(In,Ga)Se2 solar cells has been investigated using scanning near-field optical microscopy (SNOM). Topographic and photocurrent measurements have been performed simultaneously with a 100 nm tip aperture. The lamellar shaped solar cell with monolithic interconnects (P scribe) has been investigated on a nanometre scale for the first time at different regions using SNOM. It was found that, the cell region between P1 and P2 significantly contributes to the solar cells overall photocurrent generation...

Innovation in microfluidics-based biological research has been aided by the growing accessibility of versatile microscale fabrication techniques, particularly in rapid prototyping of elastomeric polydimethylsiloxane (PDMS) based devices. However, the use of PDMS presents considerable and often unexpected limitations, particularly in interpreting and validating biological data. To rapidly prototype microfluidic culture systems in conventional plastics commonly used in cell culture, we developed 'thermal scribing', a one-step micromachining technique in which thermoplastics are locally patterned by a heated tip, moving in user-controlled patterns...

We study decomposition of geometrically enforced nematic topological defects bearing relatively large defect strengths m in effectively two-dimensional planar systems. Theoretically, defect cores are analyzed within the mesoscopic Landau-de Gennes approach in terms of the tensor nematic order parameter. We demonstrate a robust tendency of defect decomposition into elementary units where two qualitatively different scenarios imposing total defect strengths on a nematic region are employed. Some theoretical predictions are verified experimentally, where arrays of defects bearing charges m=±1 and even m=±2 are enforced within a plane-parallel nematic cell using an atomic force microscopy scribing method...

BACKGROUND: Methadone is a widely used opioid agonist treatment associated with QT prolongation and torsades des pointes. We investigated the QT interval in patients treated with methadone or buprenorphine using continuous 12-lead holter recordings. METHODS: We prospectively recorded 24 h holters in patients prescribed methadone or buprenorphine, compared to controls. After their normal dose a continuous 12-lead holter recorder was attached for 24 h. Digital electrocardiograms were extracted hourly from the holter recordings...

Previous literature on the impact of scribe programs varies and has mostly been reported from academic institutions or other clinics. We report the implementation of the scribe program in the emergency room of a community hospital and its impact on patient throughput, physician productivity, and patient satisfaction. We performed a quasi-experimental, before-and-after study measuring patient throughput metrics, physician productivity, and patient satisfaction. The intervention measuring the scribe implementation was divided into pre- and post-implementation periods...

There are four prerequisites when applying all types of thin-film solar cells to power-generating window photovoltaics (PVs): high power-generation efficiency, longevity and high durability, semitransparency or partial-light transmittance, and colorful and aesthetic value. Solid-type thin-film Cu(In,Ga)S2 (CIGS) or Cu(In,Ga)(S,Se)2 (CIGSSe) PVs nearly meet the first two criteria, making them promising candidates for power-generating window applications if they can transmit light to some degree and generate color with good aesthetic value...

In this work, novel two-shell structured inhibitor-loaded poly(methacrylic acid)@cerium oxide (PMAA@CeO2) nanocontainers were synthesised and characterized. The purpose of the nanocontainers is to increase the corrosion protection provided by an epoxy coating applied to an aerospace alloy (AA 2024-T3). The (PMAA@CeO2) nanocontainers with diameters of 550 nm were synthesised by a four-step process with the method of distillation precipitation polymerization for the synthesis of the inner PMAA layer, and the sol-gel method for the development of the outer CeO2 layer...

The article by Puffer et al in this month's JABFM confirms a high burnout rate (25%) among family physicians renewing their credentials, with a higher rate among young and female doctors. Recent reports confirm high burnout rates among general internists. Thus, mechanisms to monitor and improve worklife in primary care are urgently needed. We describe the Mini Z (for "zero burnout program") measure, designed for these purposes, and suggest interventions that might improve satisfaction and sustainability in primary care, including longer visits, clinician control of work schedules, scribe support for electronic medical record work, team-based care, and an explicit emphasis on work-home balance...

Purpose: Research in other medical specialties has shown that the addition of medical scribes to the clinical team enhances physicians' practice experience and increases productivity. To date, literature on the implementation of scribes in primary care is limited. To determine the feasibility and benefits of implementing scribes in family medicine, we undertook a pilot mixed- method quality improvement (QI) study. Methods: In 2014, we incorporated 4 parttime scribes into an academic family medicine practice consisting of 7 physicians...

Solar energy storage is an emerging technology which can promote the solar energy as the primary source of electricity. Recent development of laser scribed graphene electrodes exhibiting a high electrical conductivity have enabled a green technology platform for supercapacitor-based energy storage, resulting in cost-effective, environment-friendly features, and consequent readiness for on-chip integration. Due to the limitation of the ion-accessible active porous surface area, the energy densities of these supercapacitors are restricted below ~3 × 10(-3) Whcm(-3)...

Objective Medical scribes have an emerging and expanding role in health, particularly in Emergency Medicine in the US. Scribes assist physicians with documentation and clerical tasks at the bedside while the physician consults with his or her patient. Scribes increase medical productivity. The aim of the present study was to examine the feasibility of a pilot hospital-administered scribe-training program in Australia and to evaluate the ability of an American training course (Medical Scribe Training Systems) to prepare trainee scribes for clinical training in an emergency department in Australia...

Advances in biosensors and drug delivery depend on hydrogels that respond to external stimuli. In this work we de-scribe the preparation and characterization of photoresponsive hydrogels prepared by crosslinking of di-NHS ester of azobenzoic acid and four-armed, amine-terminated poly(ethylene glycol). The porous structure and composition of the hydrogels were confirmed by scanning electron microscopy and Fourier transform infrared (FTIR) spectroscopy. The reversible photoisomerization of the azobenzene-containing hydrogel crosslinkers in the gels was confirmed by ab-sorption spectroscopy...

The Unified Protocol (UP) for the Transdiagnostic Treatment of Emotional Disorders is a cognitive-behavioral intervention designed to treat the range of anxiety, depressive, and related disorders. Thus far, the UP treatment modules have only been studied when they are delivered in their entirety and presented in a standard sequence. To personalize the presentation of the UP modules for a given patient's presentation (e.g., providing the modules in a varied order, dropping irrelevant modules), it is first necessary to establish that each module leads to change in the skill it is designed to promote, and that these changes can occur in the absence of the other modules...

There have been many successful efforts to enhance the water shedding properties of hydrophobic and superhydrophobic coatings, but durability is often a secondary concern. Here, we describe durable and hydrophobic coatings prepared via fluoride catalyzed rearrangement reaction of dodecaphenylsilsesquioxane [PhSiO1.5]12 (DDPS) with octamethylcyclotetrasiloxane (D4). Hydrophobic properties and wear resistance are maximized by incorporating both low surface energy moieties and cross-linkable moieties into the siloxane network...

Increasing use of medical scribes is an unintended consequence of electronic health record adoption in the U.S. The role of scribe is not universally defined, leading to variations in scribe training and operations, as well as questions about scribe efficiency, effectiveness, and safety. Studies published since 2009 have primarily focused on the financial aspects of scribe use, but no published studies have taken an organizational view of this phenomenon. This paper describes stakeholder perspectives on scribes working in outpatient settings within an urban tertiary academic medical center...

An extrinsic self-healing coating system containing tetraphenylethylene (TPE) in microcapsules was monitored by measuring aggregation-induced emission (AIE). The core healing agent comprised of methacryloxypropyl-terminated polydimethylsiloxane, styrene, benzoin isobutyl ether, and TPE was encapsulated in a urea-formaldehyde shell. The photoluminescence of the healing agent in the microcapsules was measured that the blue emission intensity dramatically increased and the storage modulus also increased up to 10(5) Pa after the photocuring...
