Self-supported Hierarchical Nanoporous Cu/Mo@MoOx Hybrid Electrodes as Robust Nonprecious Electrocatalysts for High-efficiency Hydrogen Evolution
Authors: Han Li-Ping , Shi Hang , Yao Rui-Qi , Wan Wu-Bin , Wen Zi , Lang Xing-You , Jiang Qing
Published: January 2021

Background:

The hydrogen evolution reaction is a crucial step in electrochemical water
splitting to generate molecular hydrogen with high purity, but it usually suffers from a sluggish reaction
kinetics in alkaline media because of additional water dissociation and/or improper adsorption
energy of reactive hydrogen intermediates. It is desirable to design highly active and robust nonprecious
electrocatalysts as alternatives to state-of-the-art commercially available Pt/C catalysts for
large-scale hydrogen production via water-alkali electrolysis.

Methods:

We developed monolithic nanoporous hybrid electrodes composed of electroactive
Mo@MoOx nanoparticles, which are seamlessly integrated on hierarchical nanoporous Cu scaffold
(Cu/Mo@MoOx) by making use of a spontaneous phase separation of Mo nanoparticles and subsequently,
self-grown MoOx in chemical dealloying.

Results:

Owing to the unique monolithic electrode architecture, in which the constituent Mo@MoOx
nanoparticles work as electroactive sites and the hierarchical nanoporous Cu skeleton serves as fast
electron-transfer and mass-transport pathways, the monolithic nanoporous Cu/Mo@MoOx hybrid
electrode exhibits superior electrocatalysis in 1 M KOH, with a low Tafel slope of 66 mV dec−1 and
outstanding stability. It only takes them ~185 mV overpotential to reach −400 mA cm−2, ~150 mV
lower than that of nanoporous Cu supported Pt/C.

Conclusion:

The outstanding electrochemical performance and excellent structural stability make
nanoporous Cu/Mo@MoOx electrodes attractive alternatives to Pt/C catalysts in alkaline-based devices.

Authors: Rastogi Sarushi , Sharma Vasudha , Gupta Meenal , Singh Pushpa , Bocchetta Patrizia , Kumar Yogesh
Published: January 2021

The concept of graphene in a carbon framework has given rise to enormous improvements
to the specific properties of materials. Notably, the combination of graphene with polymeric, metallic
and ceramic materials has significantly improved mechanical resistance, electrical and thermal conductivity,
and thermal stability of the resulting composite material. In this review, we discuss comprehensive
literature on graphene-based composite materials for biomedical and related energy storage
applications with emphasis to the synthesis techniques and improved properties of the nanocomposite
materials due to graphene addition.

Authors: Palekar-Shanbhag Pradnya , Mishra Ujala , Patil Madhura , Kamath Anusha , Kini Riddhi
Published: January 2021

Skin diseases remain a serious reason behind disability worldwide and they are ranked as
the fourth most common cause of human illness affecting one-third of human population worldwide.
Many conventional treatments are available for treating skin diseases but they have their own drawbacks.
Currently, medicated foam serves the most effective purpose. The speedy development in the
field of topical foams is because they are efficient and deliver instant absorption and have patient
compliance. Various categories of drugs such as anti-inflammatory, anaesthetics, antifungal, skin
emollients, antiseptics, antipruritics, etc. can be delivered in the form of medicated foams and have
become very important delivery system for topically active agents in dermatology.
Ratiometric and Selective Fluorescent Nanosensor for the Detection of Glucose
Authors: Qi Shengda
Published: January 2021

Background and Methods:

Dual-emission fluorescent nanosensor for the detection of
glucose has been developed by simply mixing the blue-emission C-dots (CDs) with red-emission
glutathione modified CdTe QDs.

Results and Discussion:

The ratiometric fluorescence system exhibits dual emission peaks at 442
nm and 600 nm under a single excitation wavelength (365 nm). Due to the strong quenching effect
of hydrogen peroxide to the quantum dots, the fluorescence of the QDs in the nanocomposite
system could be selectively quenched by H2O2, while the fluorescence of the CDs remained
constant, resulting in a distinguishable fluorescence color evolution (from red to blue) of the
nanosensor which could be visible through naked eye. When this nanosensor was mixed with
glucose oxidase, H2O2 can be produced by the enzyme catalysis reaction, which could quench the
fluorescent intensity of QDs. So this system can be used to detect glucose. The limit of detection of
this present method was as low as 0.1 μM.

Conclusion:

The result for glucose was satisfying, suggesting its potential application for glucose
sensing.
Stroke and COVID-19 Pandemic: The Dilemma
Authors: Mohamed Sherif , El-Mohsen Seham Abd , El-Hassan Osama Abo , AbdelHaffez Azza , El-Aziz Nashwa Abd
Published: January 2021

Background:

While the COVID-19 pandemic affected more than thirty million people
world-wide, still the true link between COVID-19 and the incidence of stroke remains to be elucidated.

Methods:

Herein, we briefly discuss virology of COVID-19 and approaches for diagnosis and treatment
of COVID-19 patients, as well as the mechanisms that link stroke and COVID-19.

Results:

Many pathophysiologic and immunologic mechanisms have been implicated in stroke occurring
among patients with COVID-19. COVID-19 pandemic has, in different ways, negative impacts
on the care of stroke patients world-wide, and still, neurologists have to face many challenges
to improve the care of stroke patients during such crisis.

Conclusions:

Although the control of the COVID-19 is of crucial importance, at the same time, the
management of stroke must not be neglected. Therefore, preserving care for critical conditions
such as stroke, and providing strategies to ensure this continues, have a priority even during the crisis.
Till vaccine is available for COVID-19, strategies for rapid diagnosis and those for treating patients
with that disease are evolving. Further studies are warranted.
Patrimônio Cultural em perspectiva decolonial : historiando concepções e práticas
Authors: Chuva Márcia
Published: January 2021

This chapter analyzes the over-dimensioning of the category of heritage, demonstrating how it has become key in public policies for cultural preservation. To the end of highlighting the historicity of the meanings of heritage, it analyzes institutional concepts and practices of cultural heritage and folklore in Brazil, makes a counterpoint between the dictionary terms of heritage and folklore and, then, formulates hypotheses about the omnipresence of the category of heritage, considering, also, the role played by UNESCO. The analysis points out anachronisms in the historiography that refers to a division between material and immaterial heritage, and demonstrates how the mobilization of an integrated conception of heritage can make explicit diverse meanings and narratives, as well as provoke a descolonial attitude towards heritage, which approaches the field of rights.
A emergência da autoria na arte popular portuguesa : o contributo de Ernesto de Sousa
Authors: Restivo Maria Manuela
Published: January 2021

In this chapter, I seek to account for the moment when, in Portuguese folk art, the figure of the author emerges, contradicting the previous dominant idea that folk art was defined by a collective creation. This change in perspective, which occurred in the mid-1950s, has Ernesto de Sousa, an artist and art theorist, as one of the main protagonists. Based on the analysis of this author's work on Portuguese folk art, I advocate the singularity of his thinking on folk art, when compared with his contemporaries, and the importance of his contribution in the inauguration of a new way of looking at this artistic production in Portugal.
COLATERAL BLOOD FLOW AT THROMBOSIS IN THE FEMORAL VENOUS COLLECTOR
Authors: Popovich Y. М. , Rusin V. V. , Kochmarh О. М. , Shitev А. І.
Published: January 2021

Anatomical features of collateral circulation of a hip influence on the severity of a clinical picture at deep thromboses and play a role in the prevention of complications. This necessitates the assessment of collateral blood flow.

The aim of research: to evaluate the compensatory possibilities of the collateral blood flow in the femoral venous collector in the acute venous thrombosis.

Methods. The analysisis made of results examination and treatment of 790 patients with the acute thrombosis in the vena cava inferior system and being treated at the Transcarpathian Regional Clinical Hospital named after A. Novak and the Transcarpathian Regional Clinical Oncology Center during 2006–2016. The laboratory methods and the instrumental ones (ultrasound duplex scanning, X-ray phlebography, computed tomography, radionuclide flebo scintigraphy and ultrasound scanning of heart) were used for investigation of patients,

Results of research. Deep vein thrombosis in the popliteal-femoral segments was observed in 322 (40.8%) of 790 patients. At the occlusion of the popliteal-femoral segments in the collateral blood flow take part the next vessels: superficial (large subcutaneous vein, small subcutaneous vein, posterior cutaneous femoral vein) and deep (deep femoral vein, vein-satellites of the main arteries, popliteal-femoral-sciaticpath, v. articularis genusuprema, vv. comitans n. ischiadici and abnormal femoral collateral), which quickly off set violations.

At the spread of thrombosis to general femoral vein, the clinical picture of the disease becomes more pronounced, due to the exclusion from the blood flow of deep femoral vein and most superficial venous collaterals (posterior cutaneous femoral vein and large subcutaneous vein), which leads to a sharp decompensation of venous outflow.

Conclusions. At the deep vein thrombosis in the popliteal-femoral segment the venouscollaterals, whichin 98.4% of cases occur secondarily, quickly compensate for hemodynamicdisorders, but at progression of thrombosis and exclusion of deep femoral and large subcutaneous veins in popliteal-femoral segments the decompensation of venous blood flow rapidly.

Thrombosis of deep veins in the popliteal-femoral segment occurs secondarily, due to the spread of thrombotic masses from the tibial veins. The jugular vein share the source of thrombosis in only 1.6% of patients.

At occlusion of a popliteal-femoral venous segment in collateral blood flow the following vessels participate: superficial (LSV, SSV, a back cutaneousvein of a hip) and deep (DFV, veins-satellites of the main arteries, popliteal-femoral-sciatic way, v. Articularis us vv. comitans n. Ischiadici and abnormal femoral collaterals), which quickly eliminate hemodynamic disturbancesin the popliteal-wall segment.

The most pronounced clinical symptoms of deep vein thrombosis in the popliteal-femoral segment are observed when excluding from the collateral blood flow of the deep femoral and great saphenous veins.

Een eeuw Gentse stokers en brouwers aan Apostelhuizen - Koepoortkaai
Authors: Hanson Marc
Published: January 2021

De voorgeschiedenis van brouwerij Meiresonne heeft nog een tweede luik, dat we hier willen beschrijven. Waar zich nu de nummers 97 en 99 van hetzelfde complex bevinden, begon Joannes Spilthoom in 1831 een jeneverstokerij. Enkele jaren later werd het een stokerij - brouwerij en nog later bleef alleen de brouwerij over. Die kende haar eigen, soms bewogen geschiedenis, tot het eind van de jaren twintig van de vorige eeuw. In 1929 verkocht de laatste eigenaar ze aan Aimé Meiresonne, die daarmee in tien jaar tijd twee Gentse brouwerijen verwierf.

In de eerste aflevering van deze serie zagen we hoe de volksjongen Joannes Spilthoorn zich opwerkte tot redelijk succesvolle kleine industrieel in een sector die vooral in de ‘Belgische Tijd’ in opmars was: de alcoholstokerij voor consumptie, bij ons vooral in de vorm van graanjenever. In 1844 wilde Spilthoorn op hetzelfde terrein ook een brouwerij opstarten. Daarom diende hij op 22 augustus van dat jaar een aanvraag in voor de installatie van een rosmolen die het mout tot schroot zou vermalen en de beslagharken zou aandrijven.

Distilleren, herhaaldelijk koken van wijn of wijndroesem (marc) en de damp laten neerslaan, noemde men branden. Het resultaat was gebrande wijn, brandewijn. Nadat men er in geslaagd was ook alcohol te distilleren op basis van granen, kenden de productie en gebruik vanaf de jaren 1500 een geweldige uitbreiding. De verkoop van alcoholische dranken is altijd al onderworpen geweest aan taksen en strenge inperkende bepalingen. De overheden hadden het vooral op de ‘sterke drank’ gemunt.

Toen men in de patriottische sfeer tussen de wereldoorlogen naar de gebruikelijke formule teruggreep, werd niet meer gesproken van Oud Gent – Vieux Gand, Vieille Flandre, etc. maar van Oud België – l’Ancienne Belgique. In Brussel en Antwerpen idem dito. De theaters hadden in deze drie steden trouwens dezelfde initiatiefnemers: de Luikse broers Mathonnet. Georges lanceerde in 1939 de instelling in de Veldstraat, die in het Gents meteen veranderde van geslacht: het werd ‘den Ancien Belgiek’, kortweg ‘den Ancien’. Het theater overleefde de tweede oorlog en kende nog tot in het begin van de jaren zestig veel succes.

Kluizenaars en vooral ‘Clusenessen’ in Gent. Uit de schatkamers van Alfons Van Werveke.
Authors: Devriese Luc
Published: January 2021

In Gent leefden vanaf minstens de veertiende eeuw tot aan de opheffing door Jozef II, vermoedelijk aldoor kluizenaars en vooral kluizenaressen (‘heremyten’ en ‘clusenessen’). In het begin van de Spaanse tijd kende het fenomeen een bloeiperiode. Het valt op dat deze vrome lieden niet willekeurig over de stad verspreid in hun kluis leefden, maar op welbepaalde plaatsen: aan de Volderskapel dicht bij de Brabantdam, bij het klooster van de tempeliers en hun opvolgers (Tempelhof) en daar dichtbij op de Geuzenberg, op het kerkhof van de Sint-Maartenskerk van Ekkergem, bij de Sint-Kwintenskapel op Sint-Pieters en op de Koutervest bij de Schipperskapel.
Het Nieuw Kasteel (1545-1576) en het Spaans Kasteel (1589-1781): tegen Gent gericht
Authors: Devriese Luc
Published: January 2021

De naam ‘Spaans Kasteel’ slaat strikt genomen niet op het ‘Nieuw Kasteel’ dat Karel V liet bouwen nadat hij de al opgeheven Sint-Baafsabdij liet afbreken, maar op het tweede bijna identieke vesting die Alexander Farnese na de gedeeltelijke vernietiging van de eerste onder het calvinistisch bewind (1577-1584) liet herbouwen in wat toen onze Spaanse Tijd was. Dat was dus geen kasteel van keizer Karel, maar wel van diens kleinzoon, zoon van Karels buitenechtelijke dochter Margaretha van Parma. Het bleef dus ‘in de familie’. De be naming Spaans Kasteel wordt gemakshalve meestal ook gebruikt voor wat Karel liet bouwen.

'Zwart hooi, verbrande oppers'. Hugo Claus en de gevaren van een wezenlijk-Vlaams landschap
Authors: Fuhrmann Aragorn
Published: January 2021

Uitgangspunt van deze bijdrage vormt een schilderijtje dat de jonge Hugo Claus vervaardigde in 1945, minder dan een jaar nadat hij met zijn familie zijn thuisstad Kortrijk was ontvlucht om aan de straatrepressie te ontkomen. Net zoals in vele andere schilderijen en gedichten van eerst geradicaliseerde en vervolgens gedesillusioneerde Vlaams-nationalisten die in de directe nasleep van de repressie tot stand kwamen, wordt in dit traditioneel-rurale tafereel een eeuwig vruchtbaar Vlaanderen opgeroepen dat – zo wordt in deze bijdrage betoogd – als een symbolische compensatie functioneert voor het uitblijven van een eigen natie. Pas in 1952, wanneer hij zijn Oostakkerse gedichten (1955) begint te schrijven, onderneemt Claus voor het eerst een volwaardige, zij het nog vrij intuïtieve poging om dergelijke discursieve landschappen en de politieke gevaren ervan op losse schroeven te zetten. Om tot een goed begrip van deze gedichten te komen, wordt in deze bijdrage daarom eerst een beeld geschetst van de beladen literaire en schilderkundige traditie waarin het wezenlijk-Vlaamse landschap een topos vormt en waartegen Claus zich later zal verzetten. Inzichten uit de internationale theorievorming rond landschap dienen daarbij als inspiratie voor een discours-analytische lezing van zowel deze traditie als Claus’ kritiek erop.__________

‘Black hay, burned ricks [Zwart hooi, verbrande oppers]’. Hugo Claus and the dangers of an essentially Flemish landscape

The starting point of this paper is a painting made by the sixteen-year old Hugo Claus in 1945, less than a year after he and his family had fled from their hometown Kortrijk in order to escape from the postwar street violence. As in so many other paintings and poems depicted by radicalised Flemish nationalists who became disillusioned after the war, this traditionalrural picture evokes a perpetually fertile Flanders which – as is argued in this paper – functions as a symbolic compensation for the enduring absence of a proper nation. It is only in 1952, when he starts writing his De Oostakkerse gedichten (1952), that Claus attempts to perturb such discursive landscapes and their inherent political dangers in a fully-fledged, yet rather intuitive, manner. To favour a good understanding of these poems, this paper first elaborates on the image of the controversial literary and painterly tradition criticised by Claus in which the essential-Flemish landscape functions as a topos. Observations from international landscape theories serve as a guideline for a discourse-analytic lecture of this tradition and Claus’s critique.

Конкуренция режимов колебаний плохо обтекаемого тела в воздушном потоке
Authors: Рябинин А.Н. , Шмигирилов Р.В.
Published: January 2021

Based on well-known mathematical models describing vibrations in the gas flow of a bluff body with one
degree of freedom, a model of vibrations of a body with two degrees of freedom is proposed.
The equations of transverse translational vibrations and rotational vibrations of an elastically fixed
body around an axis perpendicular to the velocity vector of the incoming flow are obtained.
Using the Krylov-Bogolyubov method in the first approximation, the equations are reduced to equations
for slowly varying amplitudes and frequencies of vibrations. It turned out that the differential
equations written for the squares of dimensionless amplitudes of translational and rotational
vibrations coincide with the well-known Lotka-Volterra equations describing competition between
two species of animals that eat the same food. The coefficients of the equations depend on
the velocity of the incoming flow. The model is verified in the experiments in the wind tunnel.

The regularities of the stationary degenerate four-wave mixing on transmission holographic gratings formed in the Bi12TiO20 crystal of the (110)-cut are analyzed. The system of differential equations has been obtained; this system that can be used to find the components of the vector amplitudes of linearly polarized light waves in the case of four-wave mixing on phase and phase-amplitude holographic gratings. The theoretical model take into account the linear electrooptic, the photoelastic and the inverse piezoelectric effects, as well as natural optical activity, circular dichroism and crystal absorption. The values of the orientation angle and the crystal thickness where the reflection coefficient can reach maximum values are determined. It was experimentally found that the reflection coefficient can reach 2.4 with an optimal choice of the orientation angle in the Bi12TiO20 crystal of (110)-cut with the thickness of 7.7 mm. It is shown that the best agreement between theoretical and experimental data is achieved if the phase-amplitude structure of transmission holographic gratings formed in the Bi12TiO20 crystal is taken into account in the mathematical model of diffraction.

Using an Extended Technology Acceptance Model to Understand the Factors Influencing Telehealth Utilization After Flattening the COVID-19 Curve in South Korea: Cross-sectional Survey Study (Preprint)
Authors: An Min Ho , You Seng Chan , Park Rae Woong , Lee Seongwon
Published: January 2021

BACKGROUND

Although telehealth is considered a key component in combating the worldwide crisis caused by COVID-19, the factors that influence its acceptance by the general population after the flattening of the COVID-19 curve remain unclear.

OBJECTIVE

We aimed to identify factors affecting telehealth acceptance, including anxiety related to COVID-19, after the initial rapid spread of the disease in South Korea.

METHODS

We proposed an extended technology acceptance model (TAM) and performed a cross-sectional survey of individuals aged ≥30 years. In total, 471 usable responses were collected. Confirmatory factor analysis was used to examine the validity of measurements, and the partial least squares (PLS) method was used to investigate factors influencing telehealth acceptance and the impacts of COVID-19.

RESULTS

PLS analysis showed that increased accessibility, enhanced care, and ease of telehealth use had positive effects on its perceived usefulness (P=.002, P<.001, and P<.001, respectively). Furthermore, perceived usefulness, ease, and privacy/discomfort significantly impacted the acceptance of telehealth (P<.001, P<.001, and P<.001, respectively). However, anxiety toward COVID-19 was not associated with telehealth acceptance (P=.112), and this insignificant relationship was consistent in the cluster (n=216, 46%) of respondents with chronic diseases (P=.185).

CONCLUSIONS

Increased accessibility, enhanced care, usefulness, ease of use, and privacy/discomfort are decisive variables affecting telehealth acceptance in the Korean general population, whereas anxiety about COVID-19 is not. This study may lead to a tailored promotion of telehealth after the pandemic subsides.

Authors: Denis Fabrice , Septans Anne-Lise , Le Goff Florian , Jeanneau Stephan , Lescure François-Xavier
Published: January 2021

BACKGROUND

We developed a questionnaire on a web application for analyzing COVID-19 contamination circumstances in France during the second wave of the pandemic.

OBJECTIVE

This study aims to analyze the impact on contamination characteristics before and after the second partial lockdown in France to adapt public health restrictions to further prevent pandemic surges.

METHODS

Between December 15 and 24, 2020, after a national media campaign, users of the sourcecovid.fr web application were asked questions about their own or a close relative’s COVID-19 contamination after August 15, 2020, in France. The data of the contamination’s circumstances were assessed and compared before and after the second partial lockdown, which occurred on October 25, 2020, during the second wave of the pandemic and was ongoing on December 24, 2020.

RESULTS

As of December 24, 2020, 441,000 connections on the web application were observed. A total of 2218 questionnaires were assessable for analysis. About 61.8% (n=1309) of the participants were sure of their contamination origin, and 38.2% (n=809) thought they knew it. The median age of users was 43.0 (IQR 32-56) years, and 50.7% (n=1073) were male. The median incubation time of the assessed cohort was 4.0 (IQR 3-5) days. Private areas (family’s or friend’s house) were the main source of contamination (1048/2090, 50.2%), followed by work colleagues (579/2090, 27.7%). The main time of day for the contamination was the evening (339/961, 35.3%) before the lockdown and was reduced to 18.2% (86/473) after the lockdown (P<.001). The person who transmitted the virus to the user before and after the lockdown was significantly different (P<.001): a friend (382/1317, 29% vs 109/773, 14.1%), a close relative (304/1317, 23.1% vs 253/773, 32.7%), or a work colleague (315/1317, 23.9% vs 264/773, 34.2%). The main location where the virus was transmitted to the users before and after the lockdown was significantly different too (P<.001): home (278/1305, 21.3% vs 194/760, 25.5%), work (293/1305, 22.5% vs 225/760, 29.6%), collective places (430/1305, 33% vs 114/760, 15%), and care centers (58/1305, 4.4% vs 74/760, 9.7%).

CONCLUSIONS

Modalities of transmissions significantly changed before and after the second lockdown in France. The main sources of contamination remained the private areas and with work colleagues. Work became the main location of contamination after the lockdown, whereas contaminations in collective places were strongly reduced.

Landraces play a key role in crop breeding by providing beneficial trait for improvement of related crops and their genetic diversity studies are very important for breeding program and identification of parental lines. In this study, 585 barley (Hordeum vulgare L.) landraces collected from 13 agro-ecological zones of Ethiopia were evaluated along with 10 cultivars for their phenotypic diversity and population structure in relation to agronomic traits, resistance to major diseases and barley shoot fly. Data on 22 agronomic traits, three major diseases and barley shoot fly resistance-related traits were recorded. Univariate and multivariate approaches such as principal component and cluster analyses were applied to assess the genetic diversity and population structure. The analysis of variance indicated significant genotypic main, accessions x year and accession x environment interaction effects for almost all the traits evaluated. However, the accessions x environment interactions were mainly due to changes in magnitude rather than crossover types of interactions. The diversity analysis indicated that the population was highly structured according to kernel row-type, region (geographic) origin and altitude classes. Since the population is highly structured, appropriate statistical models will be needed when this population is used for association mapping studies. Eight principal components (PCs) in principal component analysis (PCA) accounted for the variation of 83.01%. The most related traits were included in the same PC, implying that results from PCA could give clues as to the relationship among traits. Though variability existed within and among clusters, useful germplasm clustered together. These materials are important sources of germplasm for the improvement of agronomic, disease and insect pest resistance traits.

Authors: Rocha Sánchez Marco Antonio
Published: January 2021

En este trabajo se presenta un análisis del desarrollo reciente de las entidades federativas que integran la región centro de México, considerando indicadores de competitividad urbana y regional, sociales y de sustentabilidad ambiental. Los resultados indican que el crecimiento económico en las ciudades de la región tiene, como contraparte de la mayor competitividad y el nivel de vida, un impacto negativo sobre el medio ambiente urbano local y regional. En este contexto, se propone un marco de referencia para la elaboración de políticas de desarrollo regional con un enfoque metropolitano y en perspectiva megalopolitana, que permita reorientar las estrategias de política pública con base en la articulación entre economía, sociedad y medio ambiente.
Implementing Competency-Based Medical Education in Family Medicine: A Narrative Review of Current Trends in Assessment
Authors: Danilovich Natalia , Kitto Simon , Price David W. , Campbell Craig , Hodgson Amanda , Hendry Paul
Published: January 2021

Background and Objectives: The implementation of effective competency-based medical education (CBME) relies on building a coherent and integrated system of assessment across the continuum of training to practice. As such, the developmental progression of competencies must be assessed at all stages of the learning process, including continuing professional development (CPD). Yet, much of the recent discussion revolves mostly around residency programs. The purpose of this review is to synthesize the findings of studies spanning the last 2 decades that examined competency-based assessment methods used in family medicine residency and CPD, and to identify gaps in their current practices.
Methods: We adopted a modified form of narrative review and searched five online databases and the gray literature for articles published between 2000 and 2020. Data analysis involved mixed methods including quantitative frequency analysis and qualitative thematic analysis.
Results: Thirty-seven studies met inclusion criteria. Fourteen were formal evaluation studies that focused on the outcome and impact evaluation of assessment methods. Articles that focused on formative assessment were prevalent. The most common levels of educational outcomes were performance and competence. There were few studies on CBME assessment among practicing family physicians. Thematic analysis of the literature identified several challenges the family medicine educational community faces with CBME assessment.
Conclusions: We recommend that those involved in health education systematically evaluate and publish their CBME activities, including assessment-related content and evaluations. The highlighted themes may offer insights into ways in which current CBME assessment practices might be improved to align with efforts to improve health care.’

Authors: Pathoulas James T. , Blume Kylie , Penny Justin , Mansh Matthew , Rubin Nathan , Farah Ronda S.
Published: January 2021

Background and Objectives: Gender-affirming hormone therapy (GAHT) is a key component in the primary care of transgender and gender-nonconforming (TGNC) people. However, physicians are hesitant to initiate GAHT, citing a lack of knowledge. We developed an educational program for medical students and sought to investigate whether medical students’ comfort and familiarity with GAHT could increase after a short interactive program.
Methods: Second-year medical students (N=54) at the University of Minnesota were recruited to attend an hour long interactive lecture on GAHT. We calculated mean change in pre- and postintervention 5-point Likert scale scores from a survey assessing comfort and familiarity with key concepts of GAHT to assess the effectiveness of the intervention.
Results: Mean response score change increased significantly after the intervention around the use of chosen names (0.4±0.13, P<.017), the use of informed consent to initiate GAHT (1.8±0.20, P<.001), initiating and managing GAHT in the primary care setting (1.4±0.19, P<.001), medications used in GAHT (2.3±0.21, P<.001), and dosing (2.5±0.60, P<.001).
Conclusions: GAHT can be initiated and managed in a primary care setting. There is a push to introduce GAHT in the preclinical years. After participating in a short interactive lecture on GAHT, second-year medical students reported increased comfort and familiarity with GAHT. Inclusion of GAHT in the preclinical curriculum does not require significant teaching time and is important knowledge for all future physicians.
