Published: March 2022

The burden associated with using the electronic health record system continues to be a critical issue for physicians and is potentially contributing to physician burnout. At a large academic mental health hospital in Canada, we recently implemented a Physician Engagement Strategy focused on reducing the burden of electronic health record use through close collaboration with clinical leadership, information technology leadership, and physicians. Built on extensive stakeholder consultation, this strategy highlights initiatives that we have implemented (or will be implementing in the near future) under four components: engage, inspire, change, and measure. In this viewpoint paper, we share our process of developing and implementing the Physician Engagement Strategy and discuss the lessons learned and implications of this work.
Teledermatology and Artificial Intelligence: Piction Health (Preprint)
Authors: Conover Susan
Published: March 2022

BACKGROUND

Skin diseases affect 2.3 billion people globally. Due to the scarcity of dermatologists, 2 in 3 cases are seen by primary care physicians (PCPs), who have lower diagnostic accuracy. Published studies have shown that the diagnostic accuracy of a PCP or general practitioner is close to 50%.

OBJECTIVE

The aim of this study was to build artificial intelligence (AI) classifiers across 26 and 54 common and urgent adult rashes that present in a primary care setting.

METHODS

We trained our AI models with approximately 50,000 total photos. The number of images within each disease or class ranged from 76 to 5505. Additionally, we further tested narrowing the differential diagnosis by adding body part information to identify how this impacts top-5 accuracy for one condition.

RESULTS

Overall, we trained an AI model to identify 26 classes on par with the accuracy level of a dermatologist, who is, on average, 75% top-3 accurate across 26 conditions. Additionally, we trained the AI model across 54 conditions and achieved 74.3% top-5 accuracy across common conditions and 79.2% top-5 accuracy across urgent conditions. In evaluating if body part information may increase top-5 accuracy, we saw top-5 accuracy for one condition increase from 67% to 97%.

CONCLUSIONS

Overall, we concluded that including body part information to down-select possible disease matches substantially increased the overall differential diagnosis accuracy for body region–specific conditions. We also concluded that AI may assist PCPs to identify the most likely skin conditions quickly in a clinical encounter, improve overall diagnostic accuracy, and inform the most appropriate next step for the patient. These promising findings highlight the need and potential of AI and clinical decision support to augment the ability of PCPs to accurately and confidently evaluate patients with skin conditions.
Actions Speak Louder Than Words: A Sentiment and Topic Analysis of COVID-19 Vaccination on Twitter and Vaccine Uptake (Preprint)
Authors: Yousef Murooj , Dietrich Timo , Rundle-Thiele Sharyn
Published: March 2022

BACKGROUND

The lack of trust in vaccines is a major contributor to vaccine hesitancy. To overcome vaccine hesitancy for the COVID-19 vaccine, the Australian government launched multiple public health campaigns to encourage vaccine uptake. This sentiment analysis examines the effect of public health campaigns and COVID-19-related events on sentiment and vaccine uptake.

OBJECTIVE

This study aimed to examine the relationship between sentiment and COVID-19 vaccine uptake and government actions that impacted public sentiment about the vaccine.

METHODS

Using machine learning methods, we collected 137,523 publicly available English language tweets published in Australia between February and October 2021 that contained COVID-19 vaccine–related keywords. Machine learning methods were used to extract topics and sentiments relating to COVID-19 vaccination. The relationship between public vaccination sentiment on Twitter and vaccine uptake were examined.

RESULTS

The majority of collected tweets expressed negative (91,052, 66%), rather than positive (21,686, 16%) or neutral (24,785, 18%), sentiments. Topics discussed within the study timeframe included the role of the government in the vaccination rollout, availability and accessibility of the vaccine, and vaccine efficacy. There was a significant positive correlation between negative sentiment and the number of vaccine doses administered daily (r(267) = 0.15, p<.05), with positive sentiment showing the inverse effect. Public health campaigns, lockdowns and anti-vaccination protests were associated with increased negative sentiment, while vaccination mandates had no significant effect on sentiment.

CONCLUSIONS

The study findings demonstrate that negative sentiment was more prevalent on Twitter during the Australian vaccination rollout, but vaccine uptake remained high. Australians expressed anger at the slow rollout and the limited availability of the vaccine during the study period. Public health campaigns, lockdowns and anti-vaccination rallies increased negative sentiment. In contrast, news of increased vaccine availability for the public and government acquisition of more doses were key government actions that reduced negative sentiment. These findings can be used to inform government communication planning.

Mobile Health App for Tuberculosis Screening and Compliance to Undergo Chest X-ray Examination Among Presumptive Cases Detected by the App in Myanmar: Usability Study (Preprint)
Authors: Htet Kyaw Ko Ko , Phyu Aye Nyein , Thwin Thandar , Chongsuvivatwong Virasakdi
Published: March 2022

BACKGROUND

In Myanmar, the use of a mobile app for tuberculosis (TB) screening and its operational effect on seeking TB health care have not been evaluated yet.

OBJECTIVE

This study aims to report the usability of a simple mobile app to screen TB and comply with chest X-ray (CXR) examination of presumptive cases detected by the app.

METHODS

A new “TB-screen” app was developed from a Google Sheet based on a previously published algorithm. The app calculates a TB risk propensity score from an individual’s sociodemographic characteristics and TB clinical history and suggests whether the individual should undergo a CXR. The screening program was launched in urban slum areas soon after the COVID-19 outbreak subsided. A standard questionnaire was used to assess the app’s usability rated by presumptive cases. Compliance to undergo CXR was confirmed by scanning the referral quick response (QR) code via the app.

RESULTS

Raters were 453 presumptive cases detected by the app. The mean usability rating score was 4.1 out of 5. Compliance to undergo CXR examination was 71.1% (n=322). Active TB case detection among CXR compliances was 7.5% (n=24). One standard deviation (SD) increase in the app usability score was significantly associated with a 59% increase in the odds to comply with CXR (β=.464) after adjusting for other variables (P<.001).

CONCLUSIONS

This simple mobile app got a high usability score rated by 453 users. The mobile app usability score successfully predicted compliance to undergo CXR examination. Eventually, 24 (7.5%) of 322 users who were suspected of having TB by the mobile app were detected as active TB cases by CXR. The system should be upscaled for a large trial.
Extracellular Vesicles as Theranostic Tools in Kidney Disease
Authors: Huang Weijun , Zhu Xiang-Yang , Lerman Amir , Lerman Lilach O.
Published: March 2022

Extracellular vesicles are important vectors for cell-cell communication and show potential value for diagnosis and treatment of kidney diseases. The pathologic diagnosis of kidney diseases relies on kidney biopsy, whereas collection of extracellular vesicles from urine or circulating blood may constitute a less invasive diagnostic tool. In particular, urinary extracellular vesicles released mainly from resident kidney cells might provide an alternative tool for detection of kidney injury. Because extracellular vesicles mirror many features of their parent cells, cargoes of several populations of urinary extracellular vesicles are promising biomarkers for disease processes, like diabetic kidney disease, kidney transplant, and lupus nephritis. Contrarily, extracellular vesicles derived from reparative cells, such as mesenchymal stem cells, tubular epithelial progenitor cells, and human umbilical cord blood represent promising regenerative tools for treatment of kidney diseases. Furthermore, induced pluripotent stem cells–derived and engineered extracellular vesicles are being developed for specific applications for the kidney. Nevertheless, some assumptions regarding the specificity and immunogenicity of extracellular vesicles remain to be established. This review focuses on the utility of extracellular vesicles as therapeutic and diagnostic (theranostic) tools in kidney diseases and future directions for studies.
Research on Online Task-Based Teaching in English Class
Authors: Zeng Shu
Published: March 2022

In numerous countries, the COVID-19 epidemic has interrupted school, impacting tens of billions of students. As a result, in the early phases of COVID-19, the educational reaction centred on developing distant learning options as an emergency solution. Teachers are more vital than ever before, regardless of the learning methods or technology available, they play a critical role. Teachers must receive regular and effective pre-service and continuous professional development. Support the development of digital and pedagogical tools for successful distance and face-to-face teaching and learning. Distance learning must allow for meaningful two-way contact between students and teachers for it to be successful. This may be accomplished by employing the technology that is most suited to the local environment. TBLT (Task-Based Language Teaching) is task-cantered, prioritising meaning-centred communication rather than putting it at the end of the course (as PPP does)—important for anyone who considers themselves a teacher of the language of communication; tasks can mimic what students have to do outside the classroom informal professional and educational situations, either directly through “target tasks” or indirectly by engaging learners in the functions necessary for everyday communication.This article uses the TBLT approach as a basis to help teachers implement English language teaching using online education in the context of the epidemic and is also critical of the disadvantages of online education and improvements.

Introducción. La estimación de la TFG (TFGe) se realiza por ecuaciones, la mayoría aplicable dentro de un rango etario, produciéndose discrepancias en los valores al cambiar de fórmula por cruzar un límite de edad. CKD-EPI sobreestima TFG en adultos jóvenes; FAS la sobreestima para creatininemias bajas. Para minimizar sus limitaciones el European Kidney Function Consortium propuso la ecuación EKFC combinando características de diseño de FAS y CKD-EPI.

Objetivo. Evaluar comportamiento de EKFC vs. CKD-EPI y FAS en jóvenes: diferencias en TFGe y concordancia en asignación a categorías de TFG.

Materiales y métodos. Estudio analítico aprobado por Comité de Ética. Muestra: 157 estudiantes voluntarios, 18-37 años. Creatininemia: método Jaffé cinético trazable a Isotopic Dilution Mass Spectroscopy. Programa: MedCalc.

Resultados. EKFC: TFGe menores que CKD-EPI y FAS, total y por sexo. Media de las diferencias (mL/min/1,73m2): (CKD-EPI - EKFC) totales=10,42; 18-20 años=11,91; 21-30 años=11,10; 31-37 años=8,96// (FAS-EKFC) totales=2,79; FAS?110 mL/min/1,73m2 y mayor: 1,1 y 9,0 respectivamente. Asignación a categorías G: kappa menores EKFC vs. CKD-EPI que vs. FAS. Recategorización: 13,4% en G1 por CKD-EPI categorizados G2 por EKFC; 0,6% respecto a FAS, en igual sentido. Asignación a categorías ?75mL/min/1,73m2 o menor: buena concordancia.

Conclusión. En la muestra, EKFC cumple los objetivos de su diseño. La sobreestimación de TFGe por CKD-EPI en adultos jóvenes disminuyó, más fuertemente hacia los 18 años, y corrigió la de FAS para creatininemias bajas. Es clínica y epidemiológicamente importante desarrollar estimadores de TFG basados en creatininemia que cubran todo el rango de edades y estado de función renal.

El espacio entre la pantalla y la Arquitectura
Authors: Palomo-Beltrán Clementina , Reséndiz-Vázquez Aleyda
Published: March 2022

This article presents the historical and contemporary relationship that cinema and urban-architectural space have developed. Its purpose is to show the reciprocal influence between objective and virtual reality projected in science fiction films like Blade Runner, by director Ridley Scott (1982), and Ready Player One, by Steven Spielberg (2011), regarding the current perception of architectural space. The idea behind establishing the relationship between these films is highlighting the prospective used by their directors around user-architecture interaction and technology. Some of the literary and cinematographic works that address the topic of postmodern cities and the cities of the future are cited as background, either from a Utopian vision or from the perspective of a dystopia. Methodologically, a critical review of both films was carried out based on an analysis layout on the conception of architecture through its scenography or staging (Zavala, 2003), as well as the similarity with the way in which we currently travel through the architectural space with the use of mixed reality technology. In this way, the results show how mixed reality (physical and virtual) influences the perception and behavior of users within physical spaces. The conclusion expresses the inescapable presence of mixed reality in spaces as complex as those of cinema and architecture.

Published: March 2022

Actualmente, los profesionales sanitarios están sometidos a cargas laborales excesivas con enfrentamiento continuo de sufrimiento y muerte, lo que les genera altos niveles de estrés crónico. Esto aunado a frecuentes bajos salarios y reconocimiento social lleva al síndrome de desgaste ocupacional o burnout, incluso en una tercera parte, el cual comprende agotamiento emocional, despersonalización de la atención y baja realización personal, y afecta todos los ámbitos de la persona. Es pues necesario y urgente producir y aplicar conocimiento orientado a su prevención, más aún en la atención prehospitalaria por las situaciones complejas e imprevistas que implica, sin los recursos intrahospitalarios y con alto riesgo de muerte. En este libro se presenta la fundamentación y validación de un programa de “Educación experiencial” (EE) para el desarrollo de “Personalidad Resistente” (PR). La EE consiste en vivenciar situaciones similares a la realidad según objetivos definidos y luego reflexionar sobre estas situaciones, para lograr aprendizaje a partir de la experiencia. La PR comprende actitudes, afrontamiento, interacción social y autocuidado resistentes que constituyen un factor de prevención del síndrome de desgaste ocupacional. El libro, primero sigue los lineamientos de la metodología de la investigación, y al final presenta un programa modelo de educación experiencial orientado al desarrollo de la personalidad resistente en el marco de la atención prehospitalaria, aunque puede ser útil para la atención en salud y para la resistencia al estrés laboral en general.

Schistosomiasis is a tropical neglected disease commonly associated with
rural areas; however, urban schistosomiasis has been reported
world-wide, and increasing urbanization is one of the most important
demographic shifts of the 20 and now 21
centuries. The pattern of urbanization is not
uniform so that within the same city the rates and sources of population
increase vary. Here we report on the parasite composition in one
neighborhood in the metropolitan area of Salvador, Bahia, Brazil. Using
epidemiological data and population genetics we find evidence for local
transmission and maintenance of Schistosoma mansoni infection
within an urban population and little contribution from rural-urban
migration. Our findings provide direction for local mitigation
strategies and to assist the public living in this neighborhood to
interrupt the local transmission cycle.
Population genomics of a cephalopod species reflect oceanographic barriers and inbreeding patterns
Authors: Bein Bernhard , Lima Françoise , Lazzarotto Henrique , Rocha Luiz , Leite Tatiana , Lima Sergio , Pereira Ricardo
Published: March 2022

Temporal variation of effective population size and gene flow determine
current patterns of genetic diversity within species, and hence the
genetic variation upon which natural selection can act. Although such
demographic processes are well understood in terrestrial organisms, they
remain largely unknown in the ocean, where species diversity is still
being described. Here, we present one of the first population genomic
studies in a cephalopod, Octopus insularis, which is distributed in
coastal and oceanic island habitats in the Atlantic Ocean, Mexican Gulf
and the Caribbean Sea. Using genomic data, we identify the South
Equatorial current as the main barrier to gene flow between southern and
northern parts of the range, followed by discontinuities in the habitat
associated with depth. We find that genetic diversity of insular
populations significantly decreases after colonization from the
continental shelf, also reflecting low habitat availability. Using
demographic modelling, we find signatures of a stronger population
expansion for coastal relative to insular populations, consistent with
estimated increases in habitat availability since the Last Glacial
Maximum. The direction of gene flow is coincident with unidirectional
currents and bidirectional eddies between otherwise isolated
populations, suggesting that dispersal through pelagic paralarvae is
determinant for population connectivity. Together, our results show that
oceanic currents and habitat breaks are determinant in the
diversification of marine species, shaping standing genetic variability
within populations. Moreover, our results show that insular populations
are particularly vulnerable to current human exploitation and selective
pressures, calling the revision of their protection status.
Rigorous derivation of the Darcy boundary condition on the porous wall
Authors: Marusic-Paloka Eduard
Published: March 2022

Viscous flow through a reservoir with porous boundary is studied via
rigorous asymptotic analysis. Under the assumption of periodicity of the
pores, the effective boundary condition of the Darcy type is derived,
using homogenization and boundary layer techniques. Further asymptotic
analysis with respect to the porosity yields a recursive sequence of
boundary value problems showing that the large pressure jump occurs on
the boundary.
Alarmins and innate lymphoid cells 2 activation: a common pathogenetic link connecting RSV bronchiolitis and later wheezing/asthma?
Authors: Rossi Giovanni , Ballarini Stefania , Salvati Pietro , Sacco Oliviero , Colin Andrew
Published: March 2022

Severe RSV infection in infancy is associated with increased risk of
recurrent wheezing in childhood. Both acute and long-term alterations in
airway functions are thought to be related to inefficient anti-viral
immune response. The airway epithelium, the first target of respiratory
syncytial virus (RSV), normally acts as an immunological barrier able to
elicit an effective immune reaction but may also be programmed to
directly promote a Th2 response, independently from Th2 lymphocyte
involvement. Recognition of RSV transcripts and viral replication
intermediates by bronchial epithelial cells brings about release of
TSLP, IL-33, HMGB1 and IL-25, dubbed “alarmins”. These epithelial
cell-derived proteins are particularly effective in stimulating innate
lymphoid cells 2 (ILC2) to release IL-4, IL-5, and IL-13. ILC2, reflect
the innate counterparts of Th2 cells and, when activate, are potent
promoters of airway inflammation and hyperresponsiveness in RSV
bronchiolitis and childhood wheezing/asthma. Long-term epithelial
progenitors or persistent epigenetic modifications of the airway
epithelium following RSV infection, may play a pathogenetic role in the
short and long-term increased susceptibility to obstructive lung
diseases in response to RSV in the young. Additionally, ILC2 function
may be further regulated by RSV-induced changes in gut microbiota
community composition that can be associated with disease severity in
infants. A better understanding of the alarmin-ILC interactions in
childhood might provide insights into the mechanisms characterizing
these immune-mediated diseases and indicate new targets for prevention
and therapeutic interventions.

$f\in C(\R,\R)$,
$F(t)=\int_{0}^{t}f(s)ds$,
$I_{\alpha}:\R^{3}\rightarrow

$\alpha\in(0,3)$. By applying some new
analytical tricks introduced by [X.H. Tang, S.T. Chen, Adv. Nonlinear
Anal. 9 (2020) 413-437], the existence results of ground state
solutions of Poho\v{z}aev type for the above Kirchhoff
type problem are obtained under some mild assumptions on $V$ and the
general “Berestycki-Lions assumptions” on the nonlinearity $f$. Our
results generalize and improve the ones in [P. Chen, X.C. Liu, J.

Cogan syndrome is an autoimmune disorder characterized with ocular and
vestibular symptoms and only minority (less than 15%) of patients
suffer from systemic disease which is explained by autoimmuune
vasculitis.Cardiovascular involvement of Cogan syndrome is rare and
 effects mostly subclavian and carotid arteries, aortic valve or
aorta.Mitral valve involvement is rare. Below, we report a case with
mitral valve involvement and Cogan syndrome. 39 year old male patient
had admitted to our hospital with shortness of breath. He had history of
previous aortic valve implantation in 2012. His transthorasic
echocardiography demonstrated massively thickened mitral leaflets as
well as moderate to severe mitral regurgitation.Transoesaphageal
echocardiography revealed moderate to severe mitral regurgitation,
severe thickening in both mitral leaflets and and mild restriction in
leaflet motions.. Surgery was decided in case progressive dyspnea
develops. Cogan syndrome is a vasculitis which effects medium sized
arteries and aortic valve. Mitral valve involvement is rare.
Differential diagnoses , as well as using certain medical treatments and
rheumatic valve disease, were ruled out. This case is one of the rare
examples of Cogan syndrome with mitral valve thickening.
Real Exchange Rate Misalignment and Business Cycle Fluctuations in Asia and the Pacific
Authors: Ambaw Dessie , Pundit Madhavi , Ramayandi Arief , Sim Nicholas
Published: March 2022

This paper investigates the impact of real exchange rate (RER) misalignment on business cycles among 22 economies in Asia and the Pacific from 1990 to 2018. It employs a panel vector autoregression involving consumer price index (CPI) inflation, output gap, short-term interest rate, and RER misalignment. The authors find that RER overvaluation may lead to a reduction in CPI inflation and short-term interest rate. The study also illustrates Asia and the Pacific’s heterogeneity as evidenced by the output gaps of some economies, particularly in Southeast Asia, which are shown to be more susceptible to RER misalignment shocks.
