Alternative four-factor structure of the Mini-IPIP in Thailand
Authors: Fischer Ronald
Published: November 2021

This paper reports on the first study of the structure of the Mini-IPIP in Thailand. A modified version was used that included additional Honesty-Humility items. A four-factor structure was found in a Southern Thai community sample (N=212), that did not match previously reported factor structures. When using a separate student sample (N=201), the structure was partially replicated.  Two socially oriented dimensions (Social Approach versus Social Withdrawal; Traditional Affiliation), Neuroticism, and a broad Egotism factor capturing low Humility and low Conscientiousness items, emerged. The trait structure in this non-Western sample shows some meaningful divergence from standard five-factor models, suggesting possible cultural modulation of basic personality descriptions.

Electron microscopy data are used to comparative analysis of the topological structure of the surface of two samples of cellulose triacetate (СTA) films. The samples were obtained from CTA solutions without use (sample №1) and with the use of a small sodium fluoride additive that lowers the viscosity of the solution (sample №2). It is shown that in sample №1, the nodes of the physical network of macromolecules are periodically alternating regions of local orientation order - microdomains of average size d~18 nm. In sample №2, due to repackaging of microdomains on the scale R >d, a uniformly disordered fractal cluster of the mesophase CTA is formed. The fractalization of the surface and the growth of structural anisotropy are consistent with the decrease in the viscosity of the solution and explain the change in the deformation properties of sample №2 compared to №1.

Published: November 2021

High glucose levels in patients with diabetes are associated with increased plasma levels of soluble adhesion molecules. They could explain that the patients with diabetes mellitus will require the development of premature atherosclerosis related to hyperglycemia or hyperinsulinemia and that it not only affects vascular endothelium but also contributes to the development of microvascular complications. This study aimed to evaluate the serum concentration of VCAM-1 in type 1 diabetes mellitus patients with and without cardiovascular disease. Also, investigation the association of insulin levels, duration of diabetes, and HbA1C with VCAM-1. Include in this study a total of 60 types 1 diabetic patient. According to characteristic laboratory investigations and electrocardiogram (ECG), they were subdivided into two groups (G1) 30 T1DM patients without cardiovascular disease and (G2) 30 T1DM patients with cardiovascular disease in addition to 30 healthy subjects as a control group (G3). All subjects measured the levels of fasting blood glucose FBG, glycated hemoglobin HbA1c, and insulin levels, and VCAM-1 were also determined by ELISA technique. This study shows a highly significant difference in the average diabetic profile between G1 and G2 compared to the control group and found that VCAM-1 level was significantly higher among diabetic patients than the control group. Also, there was a significant negative correlation of VCAM-1 with the levels of FBG, HbA1c in diabetic patients G1 and G2. While insulin had a positive correlation in G1 but correlated negatively in G2

El cacao puede ser cultivado en asociación con árboles frutales, maderables y no maderables. Así, se evaluó el crecimiento de cuatro especies maderables y su comportamiento en la producción del cacao “CCN-51”, obtenida a partir de plantas originadas de semillas. Se plantaron en campo las especies maderables Caoba de Montaña (Colubrina arborescens (Mill.) Sarg), Fernán Sánchez (Triplaris guayaquilensis Weed), Guayacán Blanco (Cybistax donnell-smithii Rose) y Laurel Prieto (Cordia macrantha Chodat), a una distancia de 9x9 m (123 árboles ha-1), y plántulas de cacao a una distancia de 3x3 (988 plantas ha-1). Cada unidad experimental tuvo nueve árboles maderables y 40 plantas de cacao, empleandose un diseño de bloques completamente al azar con cuatro repeticiones. Durante 12 años (entre 1995 y 2007) se registró el crecimiento de las especies maderables (altura de planta, DAP, tasa de crecimiento relativo y el volumen de madera). Los componentes del rendimiento de cacao (índice de semilla, índice de mazorca, número de mazorcas sanas y rendimiento de almendras de cacao por parcela) fueron registrados durante los años 2007 y 2008. El volumen acumulado de madera fue modelado mediante un análisis de regresión sigmoidal. El volumen acumulado de madera en época seca en el año 2006 y 2007 fue significativo para el Fernán Sánchez (1,992 y 1,489 m3 árbol-1). Igualmente, está asociación incrementó el número de frutos sanos (228 y 133 mazorcas), rendimiento por parcela año (39,70 y 17,60 kg) y relativo de cacao (0,76 y 0,82). La asociación Fernán Sánchez + cacao es una excelente alternativa para sistemas agroforestales con cacao en la costa ecuatoriana.
Understanding the Predictors of Missing Location Data to Inform Smartphone Study Design: Observational Study
Authors: Beukenhorst Anna L , Sergeant Jamie C , Schultz David M , McBeth John , Yimer Belay B , Dixon Will G
Published: November 2021

Background

Smartphone location data can be used for observational health studies (to determine participant exposure or behavior) or to deliver a location-based health intervention. However, missing location data are more common when using smartphones compared to when using research-grade location trackers. Missing location data can affect study validity and intervention safety.

Objective

The objective of this study was to investigate the distribution of missing location data and its predictors to inform design, analysis, and interpretation of future smartphone (observational and interventional) studies.

Methods

We analyzed hourly smartphone location data collected from 9665 research participants on 488,400 participant days in a national smartphone study investigating the association between weather conditions and chronic pain in the United Kingdom. We used a generalized mixed-effects linear model with logistic regression to identify whether a successfully recorded geolocation was associated with the time of day, participants’ time in study, operating system, time since previous survey completion, participant age, sex, and weather sensitivity.

Results

For most participants, the app collected a median of 2 out of a maximum of 24 locations (1760/9665, 18.2% of participants), no location data (1664/9665, 17.2%), or complete location data (1575/9665, 16.3%). The median locations per day differed by the operating system: participants with an Android phone most often had complete data (a median of 24/24 locations) whereas iPhone users most often had a median of 2 out of 24 locations. The odds of a successfully recorded location for Android phones were 22.91 times higher than those for iPhones (95% CI 19.53-26.87). The odds of a successfully recorded location were lower during weekends (odds ratio [OR] 0.94, 95% CI 0.94-0.95) and nights (OR 0.37, 95% CI 0.37-0.38), if time in study was longer (OR 0.99 per additional day in study, 95% CI 0.99-1.00), and if a participant had not used the app recently (OR 0.96 per additional day since last survey entry, 95% CI 0.96-0.96). Participant age and sex did not predict missing location data.

Conclusions

The predictors of missing location data reported in our study could inform app settings and user instructions for future smartphone (observational and interventional) studies. These predictors have implications for analysis methods to deal with missing location data, such as imputation of missing values or case-only analysis. Health studies using smartphones for data collection should assess context-specific consequences of high missing data, especially among iPhone users, during the night and for disengaged participants.
COVID-19 Vaccine Tweets After Vaccine Rollout: Sentiment–Based Topic Modeling
Authors: Huangfu Luwen , Mo Yiwen , Zhang Peijie , Zeng Daniel Dajun , He Saike
Published: November 2021

Background

COVID-19 vaccines are one of the most effective preventive strategies for containing the pandemic. Having a better understanding of the public’s conceptions of COVID-19 vaccines may aid in the effort to promptly and thoroughly vaccinate the community. However, because no empirical research has yet fully explored the public’s vaccine awareness through sentiment–based topic modeling, little is known about the evolution of public attitude since the rollout of COVID-19 vaccines.

Objective

In this study, we specifically focused on tweets about COVID-19 vaccines (Pfizer, Moderna, AstraZeneca, and Johnson & Johnson) after vaccines became publicly available. We aimed to explore the overall sentiments and topics of tweets about COVID-19 vaccines, as well as how such sentiments and main concerns evolved.

Methods

We collected 1,122,139 tweets related to COVID-19 vaccines from December 14, 2020, to April 30, 2021, using Twitter’s application programming interface. We removed retweets and duplicate tweets to avoid data redundancy, which resulted in 857,128 tweets. We then applied sentiment–based topic modeling by using the compound score to determine sentiment polarity and the coherence score to determine the optimal topic number for different sentiment polarity categories. Finally, we calculated the topic distribution to illustrate the topic evolution of main concerns.

Results

Overall, 398,661 (46.51%) were positive, 204,084 (23.81%) were negative, 245,976 (28.70%) were neutral, 6899 (0.80%) were highly positive, and 1508 (0.18%) were highly negative sentiments. The main topics of positive and highly positive tweets were planning for getting vaccination (251,979/405,560, 62.13%), getting vaccination (76,029/405,560, 18.75%), and vaccine information and knowledge (21,127/405,560, 5.21%). The main concerns in negative and highly negative tweets were vaccine hesitancy (115,206/205,592, 56.04%), extreme side effects of the vaccines (19,690/205,592, 9.58%), and vaccine supply and rollout (17,154/205,592, 8.34%). During the study period, negative sentiment trends were stable, while positive sentiments could be easily influenced. Topic heatmap visualization demonstrated how main concerns changed during the current widespread vaccination campaign.

Conclusions

To the best of our knowledge, this is the first study to evaluate public COVID-19 vaccine awareness and awareness trends on social media with automated sentiment–based topic modeling after vaccine rollout. Our results can help policymakers and research communities track public attitudes toward COVID-19 vaccines and help them make decisions to promote the vaccination campaign.
Technology-Based Interventions for Cancer Caregivers: Concept Analysis (Preprint)
Authors: Su Zhaohui , Li Xiaoshan , McDonnell Dean , Fernandez Andrea A , Flores Bertha E , Wang Jing
Published: November 2021

BACKGROUND

Cancer is a taxing chronic disease that demands substantial care, most of which is shouldered by informal caregivers. As a result, cancer caregivers often have to manage considerable challenges that could result in severe physical and psychological health consequences. Technology-based interventions have the potential to address many, if not all, of the obstacles caregivers encounter while caring for patients with cancer. However, although the application of technology-based interventions is on the rise, the term is seldom defined in research or practice. Considering that the lack of conceptual clarity of the term could compromise the effectiveness of technology-based interventions for cancer caregivers, timely research is needed to bridge this gap.

OBJECTIVE

This study aims to clarify the meaning of technology-based interventions in the context of cancer caregiving and provide a definition that can be used by cancer caregivers, patients, clinicians, and researchers to facilitate evidence-based research and practice.

METHODS

The 8-step concept analysis method by Walker and Avant was used to analyze the concept of technology-based interventions in the context of cancer caregiving. PubMed, PsycINFO, CINAHL, and Scopus were searched for studies that examined technology-based interventions for cancer caregivers.

RESULTS

The defining attributes of technology-based interventions were recognized as being accessible, affordable, convenient, and user-friendly. On the basis of insights gained on the defining attributes, antecedents to, and consequences of technology-based interventions through the concept analysis process, technology-based interventions were defined as the use of technology to design, develop, and deliver health promotion contents and strategies aimed at inducing or improving positive physical or psychological health outcomes in cancer caregivers.

CONCLUSIONS

This study clarified the meaning of technology-based interventions in the context of cancer caregiving and provided a clear definition that can be used by caregivers, patients, clinicians, and researchers to facilitate evidence-based oncology practice. A clear conceptualization of technology-based interventions lays foundations for better intervention design and research outcomes, which in turn have the potential to help health care professionals address the needs and preferences of cancer caregivers more cost-effectively.
Game Plan, a Web-Based Intervention to Improve Adherence and Persistence to HIV Pre-exposure Prophylaxis and Reduce Heavy Drinking in Gay, Bisexual, and Other Men Who Have Sex With Men: Usability and User Experience Testing (Preprint)
Authors: Wray Tyler B , Chan Philip A , Kahler Christopher W
Published: November 2021

BACKGROUND

Encouraging consistent use of pre-exposure prophylaxis (PrEP) is essential for reducing HIV incidence, particularly among gay, bisexual, and other men who have sex with men (GBM), and especially those who engage in heavy drinking. Although practice guidelines recommend providing adherence counseling to PrEP patients, clinics and providers may not have the resources or expertise to provide it. Internet-facilitated interventions have been shown to improve HIV prevention outcomes, including medication and care adherence. Game Plan is a website we created to help users make a tangible plan for reducing their HIV risk. We designed additional components of Game Plan to address key individual level barriers to PrEP use.

OBJECTIVE

The aim of this mixed methods research is to test the usability and user experience of these components with intended users: GBM who drink heavily and are on PrEP.

METHODS

In study 1 (usability), we completed a detailed individual interview in which participants (n=10) walked through a prototype of the website, thinking aloud as they did, and completed a follow-up interview and web-based survey afterward. Study 2 (user experience) involved providing participants (n=40) with a link to the prototype website to explore on their own and asking them to complete the same follow-up survey afterward. Qualitative data were analyzed using thematic analysis, and descriptive statistics were used to analyze quantitative data.

RESULTS

Users in both studies gave the website excellent ratings for usability, overall satisfaction, and quality, and most often described the site as informative, helpful, and supportive. Users also rated the site’s content and feel as respectful of them and their autonomy, empathetic, and they stated that it conveyed confidence in their ability to change. The study 1 interviews highlighted the importance of the website’s esthetics to the participants’ engagement with it and its credibility in prompting genuine reflection.

CONCLUSIONS

GBM who reported heavy drinking and used PrEP generally found a website focused on helping them to create a plan to use PrEP consistently to be helpful. Adopting user-centered design methods and attending to the esthetics of mobile health interventions are important steps toward encouraging engagement and reducing at-risk behaviors.

Published: November 2021

Having a source attributed to anthropogenic activities such as incomplete combustion or pyrolysis of organic materials, polycyclic aromatic hydrocarbons are toxic organic pollutants that the ubiquity is no more to be proved. The purpose of this work is to identify and quantify the hydrocarbons pollution of the Mboppi River. Eight (8) samples of water were collected in the river during the dry and the rainy season (4samples for each season). Hydrocarbon fraction was extracted by magnetic agitation of the mixture water/hexane followed by clean-up, fractionation and subsequently, analysis using gas chromatography coupled to a Flame Ionization Detector (GC-FID). Total concentrations of polycyclic aromatic hydrocarbons in the samples were ranged between 196.3-1040.19 µg/L in the river. Polycyclic aromatic hydrocarbons with more than four rings showed the highest concentrations in the river independently from the seasonal variation while the polycyclic aromatic hydrocarbons with 2 or 3 rings were usually present in low concentrations or sometimes undetectable. From the data, it was also possible to conclude that there is predominance of petroleum sources, and essentially closed to the more industrialized areas. Mboppi River can then be considered as being among the most polycyclic aromatic hydrocarbons polluted environment in comparison with some rivers and estuaries.
Tesoros invisibles. Cómo la ocupación de las Américas en el siglo XVI influenció el surgimiento de la arquitectura como una disciplina
Authors: Ruiz Lara Fernando
Published: November 2021

Exactamente quinientos años después de la caída de Tenochtitlan, este artículo sostiene que el surgimiento de la arquitectura como disciplina autónoma y la conquista del continente americano no son sólo coincidencias cronológicas, sino variables interdependientes de un mismo proceso de modernización. La historiografía tradicional en la arquitectura no se ha detenido en absoluto en este paralelismo. Los campos de la historia y la teoría de la arquitectura todavía tratan la ocupación espacial de las Américas como consecuencia del Renacimiento y la modernización europea, a pesar de algunas décadas de literatura académica en disciplinas relacionadas que cuestionan tales supuestos –desde Franz Fanon en 1961 hasta Arturo Escobar en 1994, sin considerar los estudios fundamentales de Edmundo O’Gorman–. Tal teoría de erudición demuestra que el encuentro de 1492 y la ocupación territorial que siguió jugaron un papel central en el desarrollo de la cultura occidental, lo que nos obliga a reconocer el impacto de las teorías arquitectónicas en este proceso.

A Comparing Collaborative Filtering and Hybrid Recommender System for E-Commerce
Authors: Gomathy Dr. C. K.
Published: November 2021

Abstract: Here we are building an collaborative filtering matrix factorization based hybrid recommender system to recommend movies to users based on the sentiment generated from twitter tweets and other vectors generated by the user in their previous activities. To calculate sentiment data has been collected from twitter using developer APIs and scrapping techniques later these are cleaned, stemming, lemetized and generated sentiment values. These values are merged with the movie data taken and create the main data frame.The traditional approaches like collaborative filtering and content-based filtering have limitations like it requires previous user activities for performing recommendations. To reduce this dependency hybrid is used which combines both collaborative and content based filtering techniques with the sentiment generated above. Keywords: machine learning, natural language processing, movie lens data, root mean square equation, matrix factorization, recommenders system, sentiment analysis

The result of the experiment work shows if Olive Oil is used in the range of 5-6% it will provide better workability, less water absorption with acceptable 5-7% decrease in compressive strength.
The second language acquisition: problems and challenges for Georgian Deaf community
Authors:   Ilia State University, Tbilisi, Georgia, Makharoblidze Tamar
Published: November 2021

As stated in the title, the paper is devoted to the issue of second language acquisition by Deaf people in Georgia, describing the current situation and the challenges. There are about 2500 Deaf and hard of hearing residents in Georgia. Being the linguistic minority in the country, these people communicate with each-other in the Georgian Sign Language – GESL. The second native language for local Deaf and hard of hearing people is the Georgian spoken language – the State language. In many countries Deaf people are bilingual, while it is hard to consider the local Deaf and hard of hearing people bilingual, as the knowledge of spoken Georgian on the level of a native language among the Deaf residents is not observed. Unfortunately in Georgia there are no studies concerning the second language acquisition for Deaf and hard of hearing people. The main problems are the agrammatism in written communication on the state language and the ignorance of deferent hierarchical levels of spoken Georgian. This short paper offers the key issues for the plan of strategy of spoken Georgian acquisition for local Deaf and hard of hearing residents.
Raising EU Awareness in Ethnic MinorityAreas - Following the One Example of a JeanMonnet Project “Triangle Effect of European Studies at Schools” (TEESS)
Authors:   Caucasus University, Tbilisi, Georgia, Chelidze Guranda , Kardava Ekaterine ,   Caucasus University, Tbilisi, Georgia, Bragvadze Zurab ,   Caucasus University, Tbilisi, Georgia
Published: November 2021

In the context of European Integration of Georgia, great importance is attached to the knowledge and expectations of the population, including the ethnic minorities, regarding Georgia’s integration in the EU and implementation of the EU-Georgia Association Agreement. According to the surveys taken by various organizations, the popular mood in Georgia is positive where the EU-integration is concerned. Although the interest towards the association is substantial it does not rely on the specifics and dynamics of the bilateral relations. Mostly, the information the people get from the TV is superficial. One option to raise the popular awareness is to implement the Caucasus University Erasmus + Jean Monnet “Triangle Effect of European Studies at Schools” (TEESS) project and share the university knowledge of European Studies with public schools. The project aims at raising awareness of the European integration, the Association Agreement and DCFTA in the regions densely populated by the IDPs, namely, the school children, teachers and their families. The workshops staged in the Georgian, Russian, Armenian and Azeri public schools in the capital Tbilisi and the towns of Akhaltsikhe and Marneuli partly attended by the IDPs made the scarcity of the information and the interest evident. The discussions showed that most of them realized the importance of the EU support to Georgia. However, some of them were still skeptical. We suggest a different planning of the information campaign targeted at sharing the European values and generally the EU-Georgia relations, on the one hand and better instruction in the Georgian language in the regions populated with the ethnic minorities. The outcome of the project made it clear that supply of more comprehensive information on Europe at the history and civic education lessons to the school children could be a good option. That is what “The European Association Process in Georgia”, a quadri-lingual textbook published within the frameworks of the Caucasus University “Erasmus +” Jean Monnet project funded by the Ministry of Education and Science of Georgia is targeted at. We suppose stepping up the project activities by adding elements of informal education and last but not the least, closer involvement of public agencies and institutions.
First Person and Second Person Markers as Representatives of a Case in a Verb Form
Authors:   Ivane Javakhishvili Tbilisi State University, Tbilisi, Georgia, Bagration-davitashvili Nino
Published: November 2021

There are many various opinions regarding the definition of the person category in the scientific literature. A. Shanidze defines person category in three aspects: ”which person”, “what kind of person” and “quantity” - how many persons are represented in one form of the verb. There are two types of markers in Georgian- v- order and m-.order. They are basically divided as follows: v –order markers mainly express the markers of the subjective person and the m- order markers – the markers of the objective person. There are many cases in the language when the objective person is expressed by the subjective person marker and the subjective person is expressed by the objective person markers. This is called inversion and the verbs of these types are called inversion verbs. It is very difficult to understand and study inversion for non-Georgian students. In Georgian Linguistic Literature it is known that there is internal relationship in formation of nouns and verbs. The interrogative pronoun (who) refers only to the human and what- to all others-animate and inanimate subjects. Perhaps the v- prefix was an ancient sign of expressing the category of human and it expressed the first person in the verb, because the first person can only be human and the action of the first person means only human. He is both – the initiator of the action and the speaker. The same form of the interrogative pronoun “Who” in Nominative and Ergatrive cases makes us think that v- prefix was the representative of the Nominative and Ergative cases in the verb form. As has been noted, in the Georgian language nouns linked to a verb create constructions. There are three constructions identified in a language (based on two-person verbs): nominative construction, ergative construction and dative construction. Constructions are built according to the basic person’s cases forms (the term - basic person has been introduced by us, since the use of subjective and objective persons often cause confusion. We denote basic and non-basic person. Basic person is whom the action is mainly concerns, it either acts or is experiencing an action, is either an initiator, etc. A non-basic is a person who has a certain role in an action).

LOS NUEVOS MODELOS SOCIALES E IDENTITARIOS DE LOS ADULTOS MAYORES PROFUNDIZANDO EL CONCEPTO DE VEJEZ EXITOSA
Authors: KLEIN ALEJANDRO
Published: November 2021

Cada vez surge más evidencia en la literatura especializada que indica que la figura del adulto mayor como decrépito e inactivo comienza a ser substituida por la figura de un adulto mayor saludable y capaz de emprender nuevos proyectos de vida. El objetivo de la revisión integradora bibliográfica que se propone es analizar en las evidencias disponibles en la literatura, algunas delas implicaciones psicosociales, confrontacionales y familiares en lo que se denomina “envejecimiento de éxito” o “successful aging”. Para la selección delos artículos fueron consultadas las bases de datos electrónicos Google Scholar, Crossref, Medline, ISI. Fueron seleccionados trece estudios para la realización de la revisión sistemática utilizando el descriptor “successful aging” y “envejecimiento activo” y a partir de los mismos se profundizó interdisciplinariamente el descriptor utilizado utilizando conceptos psico-sociales y vinculares. En las conclusiones se indica que existe suficiente evidencia proveniente del campo interdisciplinario de la gerontología para poder indicar que nuevos procesos de envejecimiento se van imponiendo en las generaciones actuales de adultos mayores.

Objetivo: compreender a percepção do cuidador familiar do idoso com doença de Parkinson acerca da saúde bucal. Métodos: trata-se de um estudo descritivo, com abordagem qualitativa, realizado com 10 cuidadores familiares de idosos com a doença de Parkinson no Projeto de Extensão Pró-Parkinson: Odontologia, por meio de uma entrevista com questionário aberto com oito questões subjetivas. Os dados foram submetidos à Análise de Conteúdo e Análise Léxica, esta última utilizou o software IRAMUTEQ. Resultados: no que diz respeito à análise de conteúdo, emergiram quatro categorias temáticas, sendo estas: (1) a importância da saúde bucal para o idoso com Parkinson; (2) o papel do cuidador familiar na manutenção da saúde bucal; (3) alterações na cavidade oral provenientes do Parkinson; (4) manutenção e cuidados com a saúde bucal. Na análise léxica, houve a subdivisão em: árvore máxima de similitude; análise da nuvem representativa; classificação hierárquica descendente; e análise fatorial de correspondência, que permitiram elencar as palavras de maior centralidade no cuidado, que foram “estar”, “cuidar”, “filho”, “vez”, “prótese”, “Parkinson”, “ficar”, “dificuldade” e “banho”. Além disso, na classificação hierárquica descendente a palavra tremor estava associada às palavras saliva e boca. Considerações finais: a compreensão do processo de cuidar da saúde bucal peloscuidadores familiares através da vivência cotidiana e das orientações dos profissionais de saúde é imprescindível para a garantia da promoção da saúde e prevenção de doenças relacionadas à cavidade oral.
A Dual-origami Design Enables the Quasi-sequential Deployment and Bending Motion of Soft Robots and Grippers
Authors: Kim Woongbae , Eom Jaemin , Cho Kyujin
Published: November 2021

Soft fluidic actuators produce continuous and life-like motions that are
intrinsically safe, but current designs are not yet mature enough to
enable large deployment with high force and low-cost fabrication
methods. Here, soft fluidic actuators with two superimposed origami
architectures are reported. Driven by a fluid input, the presented
dual-origami soft actuators produce quasi-sequential deployment and
bending motion that is guided by unsymmetric unfolding of
low-stretchable origami components. The dominance between the deployment
and bending can be shifted by varying the unfolding behavior, enabling
pre-programming of the motion. The proposed origami-inspired soft
actuators are directly fabricated by low-cost fused deposition modeling
3D-printing, and subjected to a heat treatment post-processing to
enhance the fluid sealing performance. Finally, soft gripper
applications are presented and they successfully demonstrate gripping
tasks that each requires strength, delicacy, precision and dexterity.
The dual-origami approach offers a design guidance for soft robots to
embody grow-and-retract motion with a small initial form factor,
promising for applications in next-generation soft robotic systems.
Preliminary study on left bundle branch area pacing in children：clinical observation of 12 cases
Authors: Dai Wenlong , Guo Baojing , Dai Chen Cheng , Dong Jian zeng
Published: November 2021

Objective: To explore the safety and feasibility of left bundle branch
area pacing (LBBAP) in children. Methods: This study observed 12
children attempted LBBAP from 2019 to 2021 in our department
prospectively. Clinical data, pacing parameters, electrocardiograms,
echocardiographic measurements and complications were recorded at
implant and during follow-up. Results: The 12 patients aged between 3
and 14ys and weighted from 13 to 48kg. 11 patients were diagnosed with
third-degree AVB and 1 patient (case 4) suffered from cardiac
dysfunction due to right ventricular apical pacing (RVAP). LBBAP was
successfully achieved in all patients with narrow QRS complexes. LVEF of
case 4 recovered on the 3rd day after LBBAP. The median of LVEDD Z score
of the 12 patients decreased from 1.75 to1.05 3 months after
implantation (p<0.05). The median of paced QRS duration was
103ms. The median of pacing threshold, R-wave amplitude and impedance
were 0.85V, 15mV and 717Ω respectively and remained stable during
follow-up. No complications such as loss of capture, lead dislodgement
or septal perforation occurred. Conclusions: LBBAP can be performed
safely in children with narrow QRS duration and stable pacing
parameters. Cardiac dysfunction caused by long-term RVAP can be
corrected by LBBAP quickly.

Soil microbial diversity and community are determined by anthropogenic
activities and environmental conditions, which greatly affect the
functioning of ecosystem. We investigated the soil bacterial diversity,
communities, and nitrogen (N) functional genes with different
disturbance intensity levels from crop, transition, to forest soils at
three locations in the coastal region of Georgia, USA. Illumina
high-throughput DNA sequencing based on bacterial 16S rRNA genes were
performed for bacterial diversity and community analyses. Nitrifying
(AOB amoA) and denitrifying (nirK) functional genes were further
detected using quantitative PCR (qPCR) and Denaturing Gradient Gel
Electrophoresis (DGGE). Soil bacterial community structure determined by
Illumina sequences were significantly different between crop and forest
soils (p < 0.01), as well as between crop and transition soils
(p = 0.01). However, there is no difference between transition and
forest soils. Compared to less disturbed forest, agricultural practice
significantly decreased soil bacterial richness and Shannon diversity.
Soil pH and nitrate contents together contributed highest for the
observed different bacterial communities (Correlations = 0.381). Two
OTUs (OTU5, OTU8) belonging to Acidobacteriales species decreased in
crop soils, however, agricultural practices significantly increased an
OTU (OTU4) of Nitrobacteraceae. The relative abundance of AOB amoA gene
was significantly higher in crop soils than in forest and transition
soils. Distinct grouping of soil denitrifying bacterial nirK communities
was observed and agricultural practices significantly decreased the
diversity of nirK gene compared to forest soils. Anthropogenic effects
through agricultural practices negatively affecting the soil bacterial
diversity, community structure, and N functional genes.
Therapeutic Effect of His-Purkinje System Pacing Proportion on Persistent Atrial Fibrillation Patients With Heart Failure
Authors: Tong Fei , Sun Zhijun
Published: November 2021

Background His-Purkinje system pacing(HPSP) combined with
atrioventricular node (AVN) ablation is an effective therapy for atrial
fibrillation (AF) patients with heart failure (HF).However, AVN ablation
is accompanied with some limitations and disadvantages. HPSP combined
with β -blocker reduces inherent heart rate and increases pacing ratio,
which may be an alternative to HPSP combined with AVN ablation. This
study was to assess the therapeutic effect of different His-Purkinje
system pacing proportions on AF patients with HF. Methods The study
enrolled 30 consecutive persistent AF patients with HF who underwent
HPSP. Heart rate was controlled by medical therapy. New York Heart
Association (NYHA) classification, serum NT-proBNP concentration,
echocardiographic parameters were assessed at each follow-up. Results
The best cut-off value of pacing proportion to predict MACE by ROC
analysis was 71%. In high pacing proportion group, there were
significant improvements of NYHA classification, NT-proBNP
concentration, LVEF and LVEDD from the baseline in wide QRS complex
patients and HFrEF patients, and there were significant improvements in
NYHA classification, NT-proBNP concentration from baseline in narrow QRS
complex patients and HFpEF patients, moderate but no significant
improvements of LVEF and LVEDD were observed in those patients groups.
In low pacing proportion group, there were no significant improvements
of NT-proBNP concentration, LVEDD or LVEF regardless of baseline QRS
duration or LVEF (P > 0.05). Conclusion High pacing
proportion of HPSP has a beneficial effect on the prognosis of
persistent AF patients with heart failure.

Published: November 2021

Introduction/Objective A pressure ulcer is a localized injury to the skin and/or underlying tissue, usually over a bony prominence. It appears as a result of pressure or the combination of pressure and shear. Pressure ulcers can be identified within a wide variety of patient subpopulations and epidemiological and etiological aspects play a major role in their treatment. Methods A retrospective study of data analysis included 72 patients with pressure ulcers that were hospitalized and surgically treated in our institution over a five-year period. Main data features used in the analysis were sex, age, principal diseases, comorbidities, and biochemical indicators of malnutrition. The patients? data was obtained from the existing patients? records. Additionally, the study analyzed the method of treating pressure ulcers, types of reconstructive methods in surgical treatment, as well as the incidence rate of partial osteotomy. Results A total of 72 patients with pressure ulcers were included in this study, with a mean age of 54.7 ? 16.1 years. Three times more patients injured in traffic accidents were male (75% vs. 25%), while most of the patients with multiple sclerosis were female (85.7%). More than 95% of patients who had pressure ulcers of stage III or IV were treated surgically with a reconstructive method of transposition or rotation myocutaneous flap. Patients with stage IV pressure ulcer were usually treated with partial osteotomy. Conclusion Surgical reconstructive treatment with fasciocutaneous and myocutaneous flaps represents the gold standard for treating patients with pressure ulcers. These procedures provide reconstruction with adequate flap coverage and obliteration of dead space with well-vascularized tissue but with necessity of further implementation of antidecubitus measures.

Published: November 2021

Introduction/Objective The diffuse axonal injury has a very important place in clinical and forensic aspects of neurotraumatology. A special challenge is proving it in situations of short survival (less than two hours) after a craniocerebral injury. The aim of this study was to determine the efficacy of beta-amyloid precursor protein (?APP) immunohistochemical staining in postmortem diagnosis of axonal injuries in head injury survival shorter than two hours, its expression, and distribution through the brain tissue of the deceased. Methods 36 adult fatalities, both sexes, injured by acceleration-deceleration mechanisms were divided into two groups: died up to two hours and died more than two hours after the injury. Immunostaining of brain tissue samples (frontal parasagittal white mass, genu and splenium of the corpus callosum and rostral pons) was used to register ?APP positivity. Data were processed by methods of descriptive and inferential nonparametric statistics, and p < 0.05 was considered statistically significant. Results The ?APP immunopositivity was shown in 88.9% of cases (82.3% of ? two hours group vs. 94.7% of > two hours group). ?APP expression was enhanced towards the posterior structures of the brain. The shortest survival period with detected ?APP immunopositivity was 20?25 minutes, in three cases. There was an association of ?APP expression in the brainstem and interhemispheric/perimesencephalic subarachnoid hemorrhage (p = 0.035). Conclusion ?APP immunohistochemical staining is effective in proving diffuse axonal injury in casualties that survived less than half an hour. Interhemispheric/perimesencephalic subarachnoid hemorrhage may indicate a more severe form of axonal injury.

Published: November 2021

Introduction. The reconstruction of columella defects is still regarded as a challenging procedure due to the very specific anatomy of the columella and limited local and regional flap options. Furthermore, the texture and color of columella tissue pose difficulties in choosing the right method of reconstruction. Case report. The report presents a patient who underwent reconstruction of a complex columella defect using a Schmid-Meyer flap. Schmid-Meyer flap represents a tubular flap with an internal supraciliary pedicle which allows the transposition of the temporal skin with the addition of ear cartilage on the tip of the nose or the ala nasi. The integration of the flap was complete. During the five-year follow-up period, the cosmetic and functional results were satisfying. Conclusion. Schmid-Meyer flap may be one of the best options for the reconstruction of complex defects of the columella.
