Role of Wearable Technology in Measuring and Supporting Patient Outcomes following Total Joint Replacement: A Review of the Literature (Preprint)
Authors: Iovanel Gregory , Ayers David , Zheng Hua
Published: May 2022

BACKGROUND

The incidence rate of total joint replacement (TJR) continues to increase due to aging population and the surgery that is very successful in providing pain relief and improved function among patients with advanced knee or hip arthritis. Improving patient outcomes and patient satisfaction after TJR remains an important goal. Wearable technologies provide a novel way to capture patient function and activity data and supplement clinical and patient-reported outcome (PRO) measures to better understand patient outcomes after TJR.

OBJECTIVE

We examined the current literature to evaluate the potential role for wearable devices to compare with existing methods for monitoring and improving patient rehabilitation and outcomes following TJR.

METHODS

We performed a literature search to identify articles discussing the use of wearable devices in measuring and affecting outcomes of post-operative TJR patients. Selected papers were organized into a spreadsheet and categorized for analysis based on related outcome measures discussed.

RESULTS

Nine papers were selected. The literature showed generally the feasibility of wearable devices on capturing post-operative activity data and improving outcomes. Wearable-collected data were able to predict post-operative clinical measures, such as range of motion (ROM) and timed-up-and-go (TUG). When predicting PROs, specifically HOOS/KOOS and VR-12, strong associations were found between changes in sensor-collected data and in PROs over time. A wearable that provided feedback to patients significantly improved step count over time in comparison to patients not receiving feedback.

CONCLUSIONS

These findings suggest that wearable technology has potential to remotely measure and improve post-operative orthopedic patient outcomes. We anticipate that this review will facilitate further investigation of wearable devices as viable tools for guiding clinical management of TJR rehabilitation.
Implementing a virtual emergency department: a qualitative study using the NPT theory (Preprint)
Authors: Shuldiner Jennifer , Srinivasan Diya , Hall Justin N , May Carl R , Desveaux Laura
Published: May 2022

BACKGROUND

COVID-19 necessitated the rapid implementation and uptake of virtual health care; however, virtual care’s potential role remains unclear in the urgent care setting. In December 2020 the first virtual emergency department (ED) in the Greater Toronto Area was piloted at Sunnybrook Health Sciences Centre by connecting patients to emergency physicians through an online portal.

OBJECTIVE

This study aimed to understand whether and how ED physicians were able to integrate a virtual ED alongside in-person operations.

METHODS

We conducted semi-structured interviews with ED physicians guided by Normalization Process Theory (NPT). NPT provides a framework to understand how individuals and teams navigate the process of embedding new models of care as part of normal practice. All physicians who had worked within the virtual ED model were invited to participate. Data were analyzed using a combination of inductive and deductive techniques informed by NPT.

RESULTS

A total of 14 physicians were interviewed. Participant experiences were categorized into one of two groups: one group moved to normalize the virtual ED in practice, while the other described barriers to routine adoption. These groups differed in their perception of the patient benefits as well as the perceived role in the virtual ED. The group that normalized the virtual ED model saw value for patients (coherence) and were motivated by patient satisfaction witnessed (reflexive monitoring) at the end of the virtual appointment. In contrast, the other group did not find virtual ED work reflective of the perceived role of urgent care (cognitive participation) and felt their skills as ED physicians were underutilized. The limited ability to examine patients and a sense that patient issues were not fully resolved at the end of the virtual appointment caused frustration among the second group.

CONCLUSIONS

As we move into a further digitally integrated system of healthcare it will be essential to support the evolution of staff skill sets to ensure physicians are satisfied with the care they are providing to their patients, while also ensuring the technology and process is efficient and clinicians can feel good about the care they provide.

Authors: Woldamanuel Yohannes , Rossen Jenny , Andermo Susanne , Bergman Patrik , Åberg Linda , Hagströmer Maria , Johansson Unn-Britt
Published: May 2022

BACKGROUND

The trend of an exponential increase in pre- and type 2 diabetes (T2D) is projected to continue rising worldwide. Physical activity could help prevent type 2 diabetes and the progression and complications of the disease. Therefore, we need to create opportunities for individuals to acquire the necessary knowledge and skills to self-management their chronic condition through physical activity. Electronic health (e-health) is a potential resource that could facilitate self-management and thus improve population health. However, there is limited research on users’ perception of e-health in supporting self-management of physical activity in primary care settings.

OBJECTIVE

The study aims to explore the perspectives of health care professionals and individuals with pre- or type 2 diabetes on e-health as a support system for self-management of physical activity.

METHODS

A qualitative approach was applied using focus group discussions in individuals with pre- or type 2 diabetes (14 participants in four groups) and health care professionals (10 participants in two groups). The discussions were audio-recorded and transcribed verbatim. Qualitative content analysis was used inductively to code the data.

RESULTS

Three main categories emerged: utility, adoption process and accountability. The utility of e-health was described as a motivational, entertaining, and stimulating tool. Registration of daily medical measurements and lifestyle parameters in a cohesive digital platform was recognized as a potential resource for strengthening self-management skills. The adoption process includes e-health to increase accessibility of care and personalize the support for self-management of physical activity. However, participants stated that digital technology might not suit everyone and could increase health care providers' administrative burden. Accountability requires the necessary knowledge and skills to optimize e-health and ensure data integrity and security.

CONCLUSIONS

Applying e-health technology to improve self-management of physical activity in primary care settings seems feasible. People with pre- and type 2 diabetes and health care professionals proposed that a cohesive platform for personal metrics, goal setting and social support could improve self-management of physical activity. A supportive environment including technical expertise and continuous education is needed to upgrade the skills and to adopt e-health in daily clinical practice.

In our consideration, we studied the vibration analysis and dynamic responses of aHybrid Rayleigh-Van der Pol- Duffing oscillator. This system presented by one –degree-of - freedom containing the fifth order of nonlinear terms and an external force. To control the vibration of the main system, we applied the proportional derivative controller (PD). The average method used to obtain the approximate solution of the vibrating system. The stability of the system is investigated at the primary resonance case (   ). Numerically, we used Runge–Kutta of the fourth order to scrutinize the time histories of the system before and after using PD. For response curves, we investigated the performance of some chosen parameters of studied system. Finally, there is a good agreement between the approximate solution which obtained from the average method and the numerical one.
Function-oriented energy model for low power sensor nodes analysis
Authors: Vega-Gonzalez Iliover , Ramírez-Beltrán Jorge
Published: May 2022

This work presents a new energy model based on the blocks’ functions for low power sensor nodes analysis. The procedure described generalizes the majority of low power sensor nodes applications by splitting their composing blocks into only five blocks plus the power unit. For each unit, a review of the most recent low power techniques is analyzed, as well as some of the most accepted low power principles to apply in sensor nodes. The current modeling offers a generalization since most of the existing models are application-dependent and are constrained to some fields of interest, such as wireless sensor nodes. An analytical formulation is offered, and a case study is shown as a usage example.
An efficient and Highly Scalable Listless SPIHT Image Compression Framework
Authors: Al-Janabi Ali Kadhim
Published: May 2022

The set partitioning in hierarchical trees is a powerful image compression algorithm. It has reasonable complexity and produces a rate scalable bit-stream. Unfortunately, SPIHT fails to explore the multi-resolution nature of the wavelet transform as the output bit-stream doesn't support resolution scalability. Moreover it requires huge memory and has complex memory management as it depends on utilizing lists with memory of about 2.5 the image size. This paper proposes three related algorithms. The first one modifies SPIHT to reduce its complexity and improve its efficiency especially at low rates. The second is the main contribution of the paper. It provides a simultaneous solution to the memory and scalability problems of SPIHT. Memory is reduced by utilizing status bits of average 2.5 bits per pixel instead of the lists. Resolution scalability is maintained by encoding the resolution levels in increasing order within each coding pass. Another important attribute of our algorithm is that it has very little increment in complexity in comparison with the original SPIHT algorithm. In contrast, the existing solutions have much more complexity, and/or more memory resources. The third has slightly lower complexity and memory than the second but at the same time, it has slightly lower performance.

Published: May 2022

This paper examines the feasibility of using friction surfacing to deposit Aluminum alloy AA6061 material over an AISI 1017 steel substrate.  Further, this work aims to identify the deposition speed settings that would improve the effectiveness of the process. Consumable AA6061-T6 rods were deposited at different combinations of rotational and travel speeds while maintaining the same axial pressing force. The experiment involved 12 speed combinations with 3 replicates from each combination. Quantitative and qualitative methods were used to evaluate speed effects on the overall deposition quality. The evaluation involved different quality indicators including deposition efficiency and stability, surface roughness, deposit hardness and microstructure. Analysis has shown that the rotational speed is the primary factor that significantly affects all of the studied indicators. The travel speed, on the other hand, was found to have significant effects only on deposition efficiency and material hardness.

Authors: Mishra Vedant , Jha Vedant , Mishra Shivsagar , Bhonsle Om , Shaikh Mr. Kashif
Published: May 2022

Abstract: An internship is a professional learning experience that offers meaningful, practical work related to a student’s field of study or career interest. An internship gives a student the opportunity for career exploration and development, and to learn new skills. It offers the employer the opportunity to bring new ideas and energy into the workplace, develop talent and potentially build a pipeline for future full-time employees. Internships not only provide first-hand exposure to working in the real world but also allow students to harness the skill, knowledge, and theoretical practice they learnt in university. One can acquire endless amounts of education in your life; however, that knowledge doesn't always translate to working life. The great thing about internships is that it teaches young professionals about the specific industries and companies they are interested in. For engineering students, an internship is all the more important as the expectations or skill sets needed for securing a job in the industry does not match the curriculum
Diabetic Retinopathy Disease Classification Using Retina Images: A Review
Authors: Andrab Syed Efath Hamid , Gupta Ankur
Published: May 2022

Abstract: Diabetic Retinopathy (DR) is a frequent consequence of diabetes mellitus that results in vision-impairing lesions on the retina. It can cause blindness if it is not caught early. Unfortunately, DR is not a curable condition, and therapy simply keeps vision from deteriorating. Early identification and treatment of DR can lower the risk of vision loss greatly. Unlike computeraided diagnostic procedures, the physical diagnosis of DR visual fundus pictures by ophthalmologists is time-, effort-, and costintensive, as well as prone to misdiagnosis. Deep learning has recently been one of the most popular strategies for improving experience in a range of fields, particularly medical image analysis and classifications. In medical image analysis, convolutional neural networks are becoming increasingly extensively employed as a deep learning approach, and they are quite successful. The latest state-of-the-art approaches for detecting and classifying DR colour fundus pictures using deep learning techniques have been examined and analysed for this paper. In addition, the colour fundus retina datasets accessible on DR have been examined. Different difficult subjects that need further examination are also mentioned.

An artificial multi-enzyme cascade biocatalysis for biomanufacturing of nicotinamide mononucleotide from starch and nicotinamide in one-pot
Authors: Li Qiangzi , Meng Dongdong , You Chun
Published: May 2022

β-Nicotinamide mononucleotide (NMN) is an important precursor in the
synthesis of nicotinamide adenine dinucleotide (NAD+) and confers
multiple health benefits, resulting in the rapid growth of NMN market
capacity in the fields of food and health care. To overcome the
drawbacks of NMN production by the existing chemical or microbial
fermentation method, there is an urgent need to develop a prospective
NMN production strategy with low cost, low pollution, and high yield. In
this study, we demonstrated an artificial in vitro multi-enzyme cascade
biocatalysis using starch and nicotinamide (Nam) as substrates for the
synthesis of NMN in one-pot. This multi-enzyme cascade reaction was
optimized in terms of pH value, buffer concentration, inorganic
phosphate concentration, enzyme composition, and phosphoenolpyruvate
concentration. Under optimized conditions, a high molar yield of 87.8%
for NMN was achieved using 3.2 mM Nam as substrate, and a molar yield of
55.37% for NMN was also achieved under the initial Nam concentration of
9.21 mM. This in vitro enzymatic platform provides a promising and
environmental friendliness biomanufacturing technology for the
production of NMN.
Intraspecific herbivory variability, rather than species' turnover, drives latitudinal patterns in community-wide herbivory
Authors: Liu Xiang , Lin Ziyuan , Hu Kui , Wang Xingxing , Zhang Peng , Xiao Yao , Zhang Li , Liu Mu
Published: May 2022

Attempts over the past 30 years to explain geographic variation in the
strength of herbivore pressure gave rise to the latitudinal herbivory
hypothesis. However, this long-standing hypothesis has rarely been
tested using community-level data. In this study, we selected 43
grassland sites along a 1,500-km latitudinal gradient (c. 27°N to 39°N)
on the Qinghai-Tibetan Plateau. We calculated community-wide herbivory
at each site by summing herbivory across plant species weighted by the
biomass of each species; we then investigated how abiotic and biotic
latitudinal correlates drove community-wide herbivory via their effects
on intraspecific herbivory variability and species’ turnover. We found
that community-wide herbivory decreased with latitude, mirroring
intraspecific herbivory variability. Furthermore, intraspecific
herbivory variability was driven by climatic factors, but not edaphic or
plant community factors. Overall, our study highlights the importance of
considering both intraspecific herbivory variability and species’
turnover for predicting how climate change will alter community-wide
herbivory.

evidence-based evidence was lacking. Our aim was to review the most
recent evidence comparing the safety and efficacy of both treatment
modalities, single antiplatelet therapy (SAPT) and DAPT, after TAVR.
Methods: We systematically searched the literature on Embase, PubMed,
Cochrane and Medline until January 5, 2022. Our primary outcome
indicators were: all-cause mortality, stroke and total bleeding rates,
and secondary outcome indicators were: cardiovascular mortality,
myocardial infarction (MI) and the incidence of major and
life-threatening bleeding (LTB). A random-effects model was used, and
subgroup analyses were performed according to study type and follow-up
time. Results: A total of 14 studies (4 RCTs, 10 observational studies)
involving 21,546 patients were finally screened. Compared with the DAPT
treatment modality, patients in the SAPT group showed a significant
difference in short-term cardiovascular mortality after TAVR (RR [95%
CI] =0.39 [0.19-0.78], P = 0.008) and a significantly lower risk
of bleeding (RR [95% CI] =0.56 [0.48-0.65], P
<0.001). There was also a significant difference in the
incidence of major bleeding and LTB (RR [95% CI]
=0.59[0.47-0.76], P <0.0001), but no statistically
significant difference in other aspects. Conclusion: Compared with DAPT
treatment modalities, the choice of SAPT for patients without
anticoagulation indication after TAVR better reduces the risk of
postoperative bleeding and short-term cardiovascular death without
increasing the incidence of all-cause mortality, stroke, and MI.
Efficient Pavement Distress Classification via Deep Patch Soft Selective Learning and Knowledge Distillation

Pavement distress classification is a vital step for automatic pavement
inspection and maintenance. Recently, patch-based approaches have
achieved promising performances and thus extensive attention in this
field. However, these methods simply assume that all patches contribute
equally to the distress classification, leading to weakly discriminating
abilities of models. Moreover, their tedious processes also leads to a
low efficiency in inference. In this letter, we present a novel
patch-based pavement distress classification approach named Deep Patch
Soft Selective Learning (DPS$^2$L), which addresses these issues.
Similar to other patch-based approaches, DPS$^2$L partitions the
pavement images into patches and aggregates the patch features to
accomplish the task. To address the first issue, we introduce a succinct
Soft Patch Feature Selection Network (SPFSN) to assess the importance of
each patch to the distress classification with a score based on its
feature. These scores will be considered as patch-wise weights for
feature aggregation. In such a manner, the most discriminative patches
are selected in a soft way, and thereby benefit the final
classification. To address the inference efficiency issue, knowledge
distillation is leveraged to transfer the classification knowledge from
DPS$^2$L to the image-based approaches, such as EfficientNet-B3.
This distilled model enables incorporating both the advantages of
patch-based approaches in classification performance and the advantages
of image-based approaches in inference efficiency. Extensive experiments
on a large-scale pavement image dataset named CQU-BPDD demonstrates the
superiority of our methods over baselines regardless of performance or
efficiency.
La educación moral a partir de Levinas: otro modelo educativo
Authors:   Universidad de Murcia, Ortega Ruiz Pedro , Romero Sánchez Eduardo ,   Universidad de Murcia
Published: May 2022

Los autores parten de la ética y la antro­pología levinasiana como fuentes inspirado­ras de un nuevo discurso pedagógico y praxis educativa en el ámbito de la educación mo­ral. Desde este paradigma el ser humano es concebido como un ser histórico, situacional y abierto al otro desde su vulnerabilidad. De este modo, la educación moral se traduce en una respuesta de acogida compasiva al otro en su situación de especial necesidad. Los au­tores subrayan la estrecha vinculación de la educación con una determinada concepción del ser humano y su relación con los demás. Preguntar por la educación es preguntar por el hombre. La ética levinasiana no ampara la programación de pautas concretas de actua­ción educativa; solo justifica la creación de un clima educativo (ethos) en las aulas que favorezca la apertura al otro a través de una acción en los siguientes focos de intervención: la experiencia del alumno como espacio de en­cuentro; el testimonio del maestro; la aten­ción al educando en su contexto; la necesidad de profundizar en el sentido de la responsabi­lidad; la apuesta por una pedagogía del don. La educación moral, fundamentada en la éti­ca levinasiana, puede servir para desarrollar la alteridad y para humanizar a la escuela y a la sociedad.
Razones para un pacto educativo en España en el marco de una administración descentralizada

En las últimas décadas, cada vez que un nuevo partido político llega al gobierno de Es­paña, directamente se deroga en todo o en par­te la ley educativa promulgada por el gobierno anterior y, casi al mismo tiempo, se vuelve a hablar de un pacto por la educación. No obs­tante, a diferencia de la ley, el pacto nunca llega a materializarse, lo que provoca desencuentros en la clase política y grandes frustraciones en­tre los miembros de la comunidad educativa. Entre las dificultades que impiden alcan­zar un pacto se han citado motivos de carácter ideológico y político, pero también se ha culpa­do al modelo de administración educativa, in­dicando que interfiere negativamente porque su carácter descentralizado entorpece para que haya unidad en materia de educación. Este artículo muestra algunas de sus fortale­zas y las reivindica como buenas intercesoras para alcanzar un pacto educativo en nuestro país. En torno a él, cada comunidad autónoma debe cumplir unos objetivos mínimos, como paso intermedio para corregir los datos globa­les. Entre las razones que motivan un pacto educativo priorizamos las siguientes: dismi­nuir las cifras de abandono escolar, mejorar los datos de estudiantes en formación profesional, reforzar las cifras relacionadas con el gasto en educación y, en torno al profesorado, fortalecer los procesos de selección para acceder a la ca­rrera, así como la consideración social de esta profesión. Si reducimos las diferencias territo­riales mejorando los indicadores educativos, parece más probable que podamos alcanzar un consenso, antesala de un pacto por la educa­ción.
Analysis of the construction of nodes of a water pipeline network and modeling of planned overall dimensions of its working chambers

While designing water supply networks, an important task consists in establishing the place necessary for an installation of water supply wells along with water supply units located in them, in aim to determine the number of structural elements in the composition of individual pipelines of this water supply network. It has been proposed to apply a methodology for predictive calculation of a number of structural elements of the water supply pipeline system by indirect signs. An improvement of this technique was carried out by systematising the structural elements into simple and complex ones, with the determination of an indicator of the structural device for each of them. In order to analyse the role of each structural element of the same type, belonging to an assembly consisting of a linear part of a pipeline and nodes, a concept of coefficient of constructiveness was introduced. Analytical and graphical dependencies for predicting the value of the coefficient of constructiveness have been obtained. For typical (simple) nodes, the minimum value of the coefficient of constructiveness is 1.3 and maximum value is 2.54. The largest value of the coefficient of constructiveness for a conventional (complex) node is 1.45, the minimum value is 1.13. Recommendations have been given for assessment of the complexity of the installation of water supply units in practice in the design of new and reconstruction of existing water supply networks. For the above water supply units, working chambers of a round shape are recommended, which makes it possible in practice to reduce the overall planned dimensions of a water well in comparison with a rectangular shape of the same chamber.

Introduction/Objective. The class II malocclusion results in disbalanced facial harmony, primarily noticeable in the profile and the lower facial third. Aside from skeletal evaluation, orthodontic diagnosis and treatment planning should include facial soft tissue analysis. The aim of the study was to identify the soft tissue profile outcomes of orthodontic treatment of class II, division 1 malocclusion patients and to determine if these changes are related to different treatment protocols. Methods. The first group was the non-extraction group (25 patients) initially treated with the Herbst appliance, and the second group was four premolars extraction group (25 patients) treated with a multibracket appliance. The patients? cephalograms and pre- and post-treatment profile photographs were used. Results. The improvement in the non-extraction group was evident in the decrease of the nasomental angle, the angle representing the projection of the upper lip to the chin, as well as the upper lip angle. In the extraction group, the nasolabial angle showed a significant increase. Soft tissue variables showed significant differences between the groups: the total facial angle or facial convexity including the nose and the angle presenting the projection of the upper lip to the chin. Conclusion. The patients treated without extractions showed a significant improvement of the convex profile and favorable soft tissue changes in the lower third of the face.
