Effect of Digital Early Warning Scores on Hospital Vital Sign Observation Protocol Adherence: Stepped-Wedge Evaluation (Preprint)
Authors: Wong David Chi-Wai , Bonnici Timothy , Gerry Stephen , Birks Jacqueline , Watkinson Peter J
Published: March 2023

BACKGROUND

Early warning scores (EWS) are routinely used in hospitals to assess a patient’s risk of deterioration. EWS are traditionally recorded on paper observation charts but are increasingly recorded digitally. In either case, evidence for the clinical effectiveness of such scores is mixed, and previous studies have not considered whether EWS leads to changes in how deteriorating patients are managed.

OBJECTIVE

This study aims to examine whether the introduction of a digital EWS system was associated with more frequent observation of patients with abnormal vital signs, a precursor to earlier clinical intervention.

METHODS

We conducted a 2-armed stepped-wedge study from February 2015 to December 2016, over 4 hospitals in 1 UK hospital trust. In the control arm, vital signs were recorded using paper observation charts. In the intervention arm, a digital EWS system was used. The primary outcome measure was time to next observation (TTNO), defined as the time between a patient’s first elevated EWS (EWS ≥3) and subsequent observations set. Secondary outcomes were time to death in the hospital, length of stay, and time to unplanned intensive care unit admission. Differences between the 2 arms were analyzed using a mixed-effects Cox model. The usability of the system was assessed using the system usability score survey.

RESULTS

We included 12,802 admissions, 1084 in the paper (control) arm and 11,718 in the digital EWS (intervention) arm. The system usability score was 77.6, indicating good usability. The median TTNO in the control and intervention arms were 128 (IQR 73-218) minutes and 131 (IQR 73-223) minutes, respectively. The corresponding hazard ratio for TTNO was 0.99 (95% CI 0.91-1.07; P=.73).

CONCLUSIONS

We demonstrated strong clinical engagement with the system. We found no difference in any of the predefined patient outcomes, suggesting that the introduction of a highly usable electronic system can be achieved without impacting clinical care. Our findings contrast with previous claims that digital EWS systems are associated with improvement in clinical outcomes. Future research should investigate how digital EWS systems can be integrated with new clinical pathways adjusting staff behaviors to improve patient outcomes.

Higher Education in China should Increase the Proportion of Practical Teaching
Authors: Wen Jiahui , Wang Tian
Published: March 2023

With the evolution of society, the demands on human resources have also changed significantly. In the face of such changes, the field of education also needs to adapt. Current higher education in China, influenced by Confucianism, places more emphasis on theory than practice, leading to a lack of applied, innovative, and complex talents in the market, so the proportion of practical teaching should be increased. By discussing the benefits of practice for knowledge, talent development, and employment, this paper illustrates the important role of increasing the proportion of practical teaching in Chinese higher education today, guiding students to become applied, innovative and complex talents with solid theory and good quality and suggesting improvements in response to the problems currently faced by practical teaching.

Authors: Zhao Pengpeng , Wang Shuyue
Published: March 2023

The COVID-19 pandemic has caused immense damage to the world, including its impact on the global economy and public health. The pandemic has also exposed the weaknesses in the healthcare and economic systems. While many factors have influenced the global COVID-19 pandemic, there is a lack of research on the key shapers of COVID-19 and their importance. This article explores this issue through the perspectives of media, narratives of COVID-19-infected individuals, and visual images. The impact of COVID-19 on the global pandemic is analyzed from the viewpoint of self-reports and visual images of COVID-19-infected individuals. The paper suggests ways to improve preparedness for future global health crises by analyzing these issues and ensuring that we can learn from the pandemic’s memory.

Published: March 2023

The carriage of community-acquired methicillin-resistant S. aureus (CA-MRSA) has become a source of community-associated infections, particularly in the anterior nares of people worldwide. This study was aimed at determining the prevalence of community-acquired S. aureus (CA-SA) and CA-MRSA nasal carriage among healthy individuals of various ages in Kirkuk City and evaluating the susceptibility of isolates to various antibiotics. A total of 597 healthy individuals were recruited in the community between December 1, 2021, and December 30, 2022. Nasal swabs obtained from participants were taken to the laboratory, where bacteria were isolated and identified using phenotypic characteristics. The MRSA isolates were identified by applying the modified Kirby Bauer disc diffusion technique. The results showed that the prevalence of CA-SA and CA-MRSA nasal carriers was 16.6 and 4.5%, respectively. The average age of the participants was 33.2 years, with a male-to-female ratio of 1.1: 1. The highest resistance of the isolates was observed against oxacillin (27.3%), followed by penicillin G (24.3%), amoxicillin (15.2%), erythromycin (12.1%), and tetracycline (6.1%). There was a 9.1% resistance rate to clindamycin, rifampin, gentamycin, and ciprofloxacin. However, all CA-MRSA isolates were multi-drug resistant. However, all the isolates were sensitive (100 %) to vancomycin, linezolid, and mupirocin. The findings of the present study highlight the potential for CA-SA and CA-MRSA acquisition in this population, which may be related to antibiotic abuse or overuse as well as poor hygiene. To lessen the impact of community-associated strains of MRSA nasal carriage, this necessitates the probable need for infection prevention measures and adequate antibiotic therapy.

Published: March 2023

Dengue virus (DENV) is spread mostly by biting by the infected female mosquitoes of the species Aedes aegypti, that are commonly found in tropical and subtropical zones of globe. Some studies have shown that nearly fifty percent of the globe are susceptible to DENV. Most infections by DENV are asymptomatic. Clinical infections vary from mild fever to serious diseases including hemorrhagic fever and shock syndrome. The main objective of this study was to estimate DENV infection by rapid diagnostic (RDTs) kit methods in a tertiary care setting. This retrospective study was done at Crimson Hospital, Butwal, Nepal from June to November 2019. Serum samples of all dengue fever suspected patients were tested for DENV antigen as Dengue nonstructural protein 1(NS1) and DENV specific antibodies as IgM and IgG by using World Health Organization Good Manufacturing Practices (GMP) certified rapid solid phase immunochromatographic method. All laboratory test results were tabulated by using MS-Excel and analyzed by statistical package for the Social Sciences software version 20. Out of 821 samples tested, 518 were positive, including 322 (62.16%) reactive for dengue NS1 Protein, 121 (23.35%) for IgM, 62 (11.96%) for IgG and 13 (2.50%) were positive for both IgG and IgM antibodies. Our study showed high prevalence of dengue infection during monsoon to post-monsoon and the infection rate was higher in males (71.72%) than in females (53.36%). According to our findings, DENV infection is prevalent in Butwal, Nepal. Early diagnosis, better case management, faster public health response and effective health policy towards the control of mosquito vectors may reduce the dengue burden and must be implemented in Nepal.

La Función de garantía en El Estado
Authors: Antillón Montealegre Walter
Published: March 2023

Uno de los paradigmas básicos del Constitucionalismo ha sido particularmente lo que Hans Kelsen llamó “el sometimiento del derecho al derecho”, el cual, según Ferrajoli, permite verificar la disociación: a) entre forma y sustancia de la norma; b) entre vigor y validez de la misma; c) entre mera legalidad y estricta legalidad; y d) entre legitimación formal y legitimación sustancial de los actos (Ferrajoli 2014). Ese ‘derecho sobre el derecho’, este sistema de normas meta-legales de rango superior dirigidas al legislador y a los otros poderes públicos, se resume precisamente en la presencia de un doble orden normativo del Estado Moderno; y en razón de ello la Constitución Democrática es definida por dicho Autor como un acuerdo de voluntades, en primer lugar, acerca de las formas políticamente representativas de las decisiones legislativas, pero también sobre el precepto constitucional que establece lo que esas voluntades no pueden decidir (la esfera de lo no decidible), ya sea porque se trate de materia sobre la que no es lícito absolutamente decidir, o igualmente, porque se trate de materia sobre la que no se puede no decidir (Ferrajoli 2008,102).

Predicting sub-continental fuel hazard under future climate and rising [CO2] - combining ground-based observations with optimal plant behaviour in a machine learning approach

Published: March 2023

Bushfire fuel hazard is determined by fuel hazard that represents the
type, amount, density, and three-dimensional distribution of plant
biomass and litter. The fuel hazard represents a biological control on
fire danger and may change in future with plant growth patterns. Rising
atmospheric CO2 concentration (Ca) tends to increase plant productivity
(‘fertilisation effect’) but also alters climate, leading to a ‘climatic
effect’. Both effects will impact on future vegetation and thus fuel
hazard. Quantifying these effects is an important component of
predicting future fire regimes and evaluating fire management options.
Here, by combining a machine learning algorithm that incorporates the
power of large fine-resolution datasets with a novel optimality model
that accounts for the climatic and fertilisation effects on vegetation
cover, we developed a random forest model to predict fuel hazard at fine
spatial resolution across the state of Victoria in Australia. We fitted
and evaluated model performance with long-term (i.e., 20 years),
ground-based fuel observations. The model achieved strong agreement with
observations across the fuel hazard range (accuracy >65%).
We found fuel hazard increased more in dry environments to future
climate and Ca. The contribution of the ‘fertilisation effect’ to future
fuel hazard varied spatially by up to 12%. The predictions of future
fuel hazard are directly useful to inform fire mitigation policies and
as a reference for climate model projections to account for fire
impacts.

Three novel Iridium(III) complexes containing double chiral atoms for OLEDs
Authors: Cheng Gan , Lu Junjian , Zhu Li-ya , Lu Gaozhao
Published: March 2023

Chiral Iridium complexes are very important for the preparation of
circularly polarized light emitting diodes (CP-OLEDs). Three novel
Iridium(III) complexes, Ir(dnfppy)2(Cl/pyrrole), Ir(dfppy)2(dpp) and
Ir(tfmqz)2(sdpp) have been synthesized and characterized, respectively.
These Iridium(III) complexes emitted deep-blue, blue and red
photoluminescence with high quantum yields, for
((Ir(dnfppy)2(Cl/Pyrrole): λmax=447 nm, F=62.4%; Ir(dfppy)2(dpp):
λmax=467 nm, F= 25%; Ir(tfmqz)2(sdpp): λmax=609 nm, F=73.7%). Compared
with Ir(dnfppy)2(Cl/pyrrole), HOMO energy level of Ir(dfppy)2(dpp) and
Ir(tfmqz)2(sdpp) was calculated to be −5.71/-5.73 eV, and LUMO energy
level increased to be -2.75/-3.36 eV, respectively. CD spectra of two
pairs of the enantiomers for Ir(dfppy)2(dpp) or Ir(tfmqz)2(sdpp)
displayed symmetry with opposite polarization between 300 and 600 nm.
The maximum external quantum efficiency (EQEmax) of OLEDs based on
Ir(tfmpqz)2(sddp) was 13.8%, showing a relatively low efficiency
roll-off with the EQE of 10.7% at 5000 cd/m2.

The tuberous root of Tinospora sagittata (Oliv.) Gagnep is the
original plant of Traditional Chinese Medicine Tinosporae Radix
(“Jin Guo Lan”), which usually be used to treat pharyngeal arthralgia,
carbuncle furuncle, bacillary dysentery, abdominal pain and
inflammation. Twenty-six clerodane diterpenoids were isolated from
T. sagittata, including 8 new clerodane diterpenoids (tinotanoid
A-H: 1-8), and 18 known ones (9-26).
The absolute configurations of compounds 1, 2,
5, 8, 13, 17 and 20 were
determined by single-crystal X-ray diffraction. Compound 1 is
the first example of clerodane diterpenoid with a γ lactone ring
which were constructed between C-11 and C-17. Compound 2 and
17 is a pair of epimer. Compounds 2, 12 and
17 showed excellent inhibitory activity on NO production with
IC50 values of 9.56±0.69, 9.11±0.53 and 11.12±0.70 μM, respectively, and
the activities were significantly stronger than the positive control
Minocycline (Mino) (IC50 value was 23.57±0.92 μM). Moreover, compounds
2, 12 and 17 dramatically reduced the expressions of
iNOS and COX-2 up-regulated by LPS treatment. Compounds 2 and
12 can significantly inhibit the levels of pro-inflammatory
cytokines TNF-α, IL-1β and IL-6 that are increased by LPS
stimulation.
Visual speech cues enhance neural speech tracking in right auditory cluster leading to improvement in speech in noise comprehension in older adults with hearing impairment
Authors: Frei Vanessa , Schmitt Raffael , Meyer Martin , Giroud Nathalie
Published: March 2023

Comprehending speech in noisy situations is difficult and suffers with
aging, hearing loss, and cognitive decline. Using visual speech cues
improves perception and comprehension of speech in noise (SiN) in older
adults with hearing impairment. In the current study we investigated
neurofunctional correlates (i.e., neural tracking of speech) of the
visual enhancement effect in a naturalistic setting in which older
adults with hearing impairment (N=67) listened to sentences in babble
noise in audio-only and audiovisual conditions and performed an
intelligibility and a comprehension task, while EEG was recorded.
Behaviorally, we found that visual speech cues improved intelligibility
and comprehension of speech presented in babble noise and that
particularly individuals with high working memory capacity benefitted.
Furthermore, we found that the visual enhancement effect was accompanied
by increased cortical tracking of the speech envelope particularly in
individuals who were low performers in the audio-only condition (i.e.,
< 70% correct) leading to improved speech in noise
comprehension in an audiovisual setting. Further, these low
auditory-only performers showed deficient neural speech tracking in a
right auditory topographical cluster, which improved significantly when
visual speech cues were presented leading to more bilateral processing
of speech. Overall, our results show that older adults with hearing
impairment who have difficulties with speech in noise perception use
visual speech cues to improve performance which is reflected in more
bilateral processing of speech.

viscoelasticity, Academic Press, New York, USA, 2020]. The solution of the
mathematical model is obtained with the aid of Laplace transform. The
comparison among the classical and anomalous relaxation models is discussed
in detail. This result is proposed as a mathematical tool to model the
anomalous relaxation behavior of the complex materials.
Optimal solution of pentagonal fuzzy transportation problem using a new ranking technique
Authors: Bisht Monika , Beg Ismat , Dangwal Rajesh
Published: March 2023

In this article, we propose a method based on a new ranking technique to find optimal solution for a pentagonal fuzzy transportation problem. Firstly, the proposed ranking method which is based on the centroid concept is applied. This transforms the pentagonal fuzzy transportation problem to crisp transportation problem and then the proposed algorithm is applied to find optimal solution of the problem in crisp form. Also, a new method to find initial basic feasible solution (IBFS) of crisp valued transportation problems is introduced in the paper. Further, we give two numerical illustrations for the newly proposed algorithm and compare the solution obtained with the solutions of existing methods. The proposed method can easily be understood and applied to real life transportation problems. Moreover, the proposed ranking method can be used to solve various other fuzzy problems of operations research.

In order to determine the effect of anodic oxidation, microhardness, friction coefficient, wear resistance, vibration, and worn surface images of the samples were evaluated. It was concluded that anodic oxidation significantly improved the hardness, friction coefficient, and wear resistance of the samples.
Influence of the transition layer material on the etched pattern of multilayer films
Authors: Liu Xiaoli , Lei Qian , Wang JiZhou , Xiong Yuqing , Shang Kaiwen , Yang Bingze
Published: March 2023

High-quality frequency-selective surfaces (FSSs) exert a crucial role in the absorption and filtration of electromagnetic signals. FSS is made from structure-function-integrated materials with a patterned metal layer cover. Cr or Ni transition layers are usually arranged between the material substrate and the metal layer to enhance their bonding. However, the study on the removal behavior of Al/glass and Al/Ni/glass films by laser ablation with a pulse width of 100 ns of the 1064 nm laser found that the Ni transition layer increases the damage threshold of Al films because its thermophysical parameters changed the laser absorption rate of the Al surface and the spatial temperature distribution inside the Al film. The experimental results show that four characterized areas in the laser ablation surface are identified in the machined grooves when the laser energy density is 12 J/cm2, indicating that the multilayer films are mainly removed by vaporization, phase explosion, melting, and fragmentation. It is found that the removal mechanism of the Al/Ni/glass system is dominated by melting heat stress and fragmentation, so splashing is obvious and results in residual recondensation droplets of micrometer size. The above results provide ideas and methods for other high-quality laser processing of structure-function-integrated film systems.
Record linkage for Routinely Collected Health Data in an African Health Information Exchange

Published: March 2023

IntroductionThe Patient Master Index (PMI) plays an important role in management of patient information and epidemiological research, and the availability of unique patient identifiers improves the accuracy when linking patient records across disparate datasets. In our environment, however, a unique identifier is seldom present in all datasets containing patient information. Quasi identifiers are used to attempt to link patient records but sometimes present higher risk of over-linking. Data quality and completeness thus affect the ability to make correct linkages.
AimThis paper describes the record linkage system that is currently implemented at the Provincial Health Data Centre (PHDC) in the Western Cape, South Africa, and assesses its output to date.
MethodsWe apply a stepwise deterministic record linkage approach to link patient data that are routinely collected from health information systems in the Western Cape province of South Africa. Variables used in the linkage process include South African National Identity number (RSA ID), date of birth, year of birth, month of birth, day of birth, residential address and contact information. Descriptive analyses are used to estimate the level and extent of duplication in the provincial PMI.
ResultsThe percentage of duplicates in the provincial PMI lies between 10% and 20%. Duplicates mainly arise from spelling errors, and surname and first names carry most of the errors, with the first names and surname being different for the same individual in approximately 22% of duplicates. The RSA ID is the variable mostly affected by poor completeness with less than 30% of the records having an RSA ID.
The current linkage algorithm requires refinement as it makes use of algorithms that have been developed and validated on anglicised names which might not work well for local names. Linkage is also affected by data quality-related issues that are associated with the routine nature of the data which often make it difficult to validate and enforce integrity at the point of data capture.
Enseñar el deporte en la escuela mediante juegos modificados: una enseñanza para la comprensión
Authors: Murrieta Ortega Raymundo
Published: March 2023

El objetivo de esta investigación fue identificar el modelo pedagógico ideal para la iniciación deportiva en el contexto escolar. El estudio surge a partir de observar la forma en que se inician en el deporte los alumnos de primaria en los contextos de Puebla, México, y Cuenca, España. Se parte de la siguiente pregunta: ¿cuál es el modelo pedagógico idóneo para la enseñanza del deporte en la escuela? El estudio se fundamenta en la teoría de meta del logro (Cecchini, Méndez y García, 2019). El método utilizado en la investigación corresponde al enfoque cualitativo, con diseño narrativo, a partir de una entrevista semiestructurada aplicada a una estudiante de sexto semestre de una licenciatura en educación física de México, que realizó prácticas docentes en escuelas primarias de Puebla y Cuenca. Los datos obtenidos permiten identificar, en el contexto poblano, el excesivo uso de la instrucción directa y la repetición de gestos técnicos para la depuración de habilidades motrices de los noveles deportistas, además de la escasa adopción de modelos pedagógicos que favorezcan la inclusión de todos los alumnos en el deporte escolar. En contraparte, en Cuenca se identifica que el paradigma adoptado por el docente titular del curso de Educación Física es inclusivo, participativo y enfocado en la comprensión a partir del uso de juegos modificados en lugar del deporte estándar. Se concluye que la enseñanza del deporte en la escuela mediante un modelo lúdico-comprensivo corresponde a las necesidades formativas de los alumnos del siglo XXI.

Published: March 2023

As many sources exhort managers to “think strategically,” only a few addresses how to make this happen. Where strategic analysis tools are explained, this is most frequently done conceptually rather than their actual application in strategic planning. Shortened systematic strategic planning (SSP) consists of a pattern of step-wise procedure for straight-forward planning, and the fundamentals involved in any strategic planning project. The use of shortened SSP is more suitable for the development of strategic plans for small- and medium-size businesses (SMEs). SSP has been applied to and tested on different businesses’ subject issue and has been generated by the composition of the cause-and-effect relations of them. The intention here is to provide a new perspective and benefit for the strategic planners by introducing this new systematic methodology and demonstrating its implementation on an entrepreneurial and new business called Natural Food. Accordingly, let shortened version of SSP easily understood and universally applied to any small- and medium-size businesses. Additionally, you are guided how to identify in what circumstances you might use its specific tools and how to target them directly at achieving effective results. The data that are used in this case are fictitious and only help for this study. Though, the given case does not cover all the steps of a typical systematic strategic plan and use all the recommended techniques, it still reflects the basics.

Authors: Y. Shakor Mohammed , Surameery Nigar M. Shafiq , N. Khlaif Zuheir
Published: March 2023

A cloud computing environment provides a cost-effective way for end-users to remotely store and retrieve private data through an internet connection anytime and anywhere. The security of these data cannot always be guaranteed because they can only be accessed by the end-user through a third-party interface, making them vulnerable to potential breaches of authentication and data integrity. This paper presents a secure hybrid approach for a medical image stored in the cloud that prioritizes data security and integrity. The suggested model employs a combination of Elliptic Curve Cryptography (ECC) and Advanced Encryption Standard (AES) algorithms to ensure authentication and data integrity. The results demonstrate its superiority over existing methods making the proposed model compliant with regulations of sensitive data stored in the cloud, such as the Health Insurance Portability and Accountability Act (HIPAA) and General Data Protection Regulation (GDPR) that dictate how personal information must be handled, stored, and processed. By contrast with traditional and other hybrid systems, this paper can conclude that this is one of the best methods to guarantee the security of medical images in the cloud.
