Experimental analysis of infiltration process and hydraulic properties in soil and rock profile in the Taihang Mountains, North China
Authors: Cao Jiansheng , Yang Hui , Zhao Yong
Published: September 2021

In this research, an experiment was conducted in the Taihang Mountains in China with a self-designed automatic soil and rock water infiltration monitoring system and a time domain reflectometry (TDR) device to analyze the infiltration process of disturbed soil and rock profile under constant head, unsaturated seepage properties and permeability coefficient of discontinuous rock masses. It was found that the infiltration process curve has an obvious fluctuation in the late stage of unsaturated seepage (after 18:00 p.m. on March 20th) which not only reflects the temporal variation of infiltration rate, but the spatial variation of rock structure. The lateral soil water of soil and rock dual-texture mainly flows in the interface of soil and rock. The infiltration rate of soil water can be as high as 2.42 × 10−4 cm/s, accounting for about 20% of the stable infiltration rate. After the water infiltrated in the lower rock layers, the water was mainly stored and flowed in the fissure network in the rocks, but did not completely fill the whole fissure network. Firstly, the local priority channel is adopted to infiltrate. With the increasing of rock saturation, the local priority channel will also expand and finally extend to the whole fissure network. The permeability coefficient of the soil and rock dual-texture in the study area is 1.26 × 10−3 cm/s.

Authors: Chaudhari Ankit N. , Mehta Darshan J. , Sharma Neeraj D.
Published: September 2021

Groundwater quality is a major problem for humanity since it is closely related to human health. The flow of seawater into freshwater aquifers is known as saltwater intrusion, and it can lead to groundwater quality contamination, including drinking water. Due to the extremely severe hydraulic interface between groundwater and seawater, saltwater intrusion can happen naturally in coastal aquifers. The aim of the study is to examine the status of seawater intrusion within the study region of the South-West zone of Surat city, Gujarat. The present study evaluates Groundwater Quality Index using a weighted arithmetic method including various chemical ions. The South-West zone of Surat city is located along the coast; seawater infiltration has a significant impact on the groundwater in the state. The conceptual model will be developed and analyzed using MODFLOW to analyze the effects of seawater intrusion analysis. The model domain is characterized by three hydro-stratographic layers and covers an area of approximately 110 km2 in a 400 m × 400 m grid size. An analytical study with MODFLOW would be carried out for three-dimensional groundwater flows with species of solute transport. This study would help profile the study area regarding groundwater quality.

Authors: Wang Jun , Garg Ankit , Huang Shan , Mei Guoxiong , Liu Jiaqin , Zhang Kexin , Gan Lin
Published: September 2021

Rainfall infiltration, rainwater retention, runoff and evapotranspiration (ET) are important components of the water balance in green roofs. These components are expected to be influenced by variations in the structural configurations (i.e., substrate layers) of green roofs. This study explores the influence of layered soil and green roof configurations on the rainwater retention capacity (RRC) of the roofs as compared to conventional improvements (i.e., soil conditioning and enhanced substrate depth). Ten different extensive green roof modules were designed by varying the substrate materials, substrate depths, storage/drainage layers and vegetation layers. For all modules, the RRCs ranged from 34 to 59%. The RRCs of layered soil were 1–4% higher than that for single-layer soil. The RRC increased by 13% in the presence of a water storage module. It can be concluded that highest RRC corresponds to a combination of high-permeability soil in the upper layer along with a relatively large water holding capacity in the deep layer. Water storage layer and layered soil could significantly delay the water stress in vegetation. The importance of wick irrigation, vegetation types, back-to-back rain events and the ET rate on the RRC were also discussed.

Authors: Do Vale Gatti Giseli Cristina , Gatti Júnior Décio
Published: September 2021

Neste texto são analisadas as práticas escolares desenvolvidas em torno do civismo, do patriotismo e do catolicismo nas escolas brasileiras, destacadamente, no Gymnásio Mineiro de Uberlândia (Minas Gerais, Brasil), no período compreendido entre as décadas de 1930 e 1950. Partiu-se principalmente das ideias de Souza (1998), Bencostta (2001) e Silva (2009). As fontes de pesquisa incluíram manuscritos, impressos, iconografia e depoimentos de antigos alunos e professores da escola. Os resultados da pesquisa permitem concluir que a escola estudada, bem como aquelas de sua proximidade, comportava de modo reiterado e consistente uma dimensão formativa de caráter cívico e patriótico, em colaboração com as escolas católicas, para além das funções de aquisição de conhecimentos e de preparação para o trabalho. De fato, na memória dos sujeitos que habitavam a instituição escolar no período coberto pela investigação, os desfiles cívico-patrióticos estão muito presentes e ganham centralidade em relação a outras importantes vivências escolares.
Different Sides of Depression in the Elderly: An In-depth View on the Role of Aβ Peptides
Authors: Pagni Giovanni , Tagliarini Claudia , Carbone Manuel Glauco , Imbimbo Bruno Pietro , Marazziti Donatella , Pomara Nunzio
Published: September 2021

Background:

Late-onset depression (LOD) is the most common neuropsychiatric
disorder associated with Alzheimer's disease (AD), often associated with structural and functional
brain changes, neuropsychological impairments and negative family history for affective
disorders. LOD could be a risk factor or a prodromal phase of AD; this has led to the investigation
of the link between depression and amyloid-β (Aβ) peptides by measuring Aβ levels in
plasma, cerebrospinal fluid (CSF) and brains of elderly depressed subjects.

Objective:

This study aims to clarify the complex relationship between depression, Aβ
peptides and AD.

Method:

We evaluated all articles published up to 2019 in PubMed in which Aβ was
measured in serum (or plasma), CSF or brain in elderly with Major Depressive Disorder
or depressive symptoms evaluated with standard scales.

Results:

Low plasma Aβ42 levels are strongly associated with depression severity. Plasma
Aβ40 levels are higher in younger depressed, drug-resistant and those with more severe
symptoms. CSF Aβ42 levels are lower in depressed than controls. PET-detected global
and region-specific increases in Aβ deposition are sometimes associated with LOD,
cognitive impairment, anxiety but not with Cardiovascular Diseases (CVDs)/CVD risk
factors. Elderly depressed with CVDs/CVD risk factors have more frequently high plasma
Aβ40 levels and drug-resistance; those without these co-morbidities have low plasma
Aβ42 levels and greater cognitive impairment.

Conclusion:

Two specific Aβ profiles emerge in the depressed elderly. One is associated
with Aβ42 reductions in plasma and CSF, possibly reflecting increased brain amyloid
deposition and prodromal AD. The other one is characterized by high plasma Aβ40 levels,
cerebrovascular disease and is clinically associated with increased AD risk.

Authors: Podiyanachari Santhosh Kumar , Bazzi Hassan S. , Al-Hashimi Mohammed
Published: September 2021

Synthesis of cycloolefin-based polymers via metathesis-accompanied cyclopolymerization
and tandem Ring-Opening/Ring-Closing Metathesis (RO/RCM) polymerization are
undergoing exciting developments and emerging as an area of great interest in the field of
polymer synthesis. Among the conventional polymerization techniques, both cyclopolymerization
and tandem polymerization give access to highly functional cycloolefin ring-based polymers.
This review provides an overview of the synthesis of such cycloolefin-based conjugated
and non-conjugated polymers following cyclopolymerization and tandem RO/RCM polymerization
methodologies.

ST19 and ST213 Genotypes on Pathogenesis and Stress Response Pathways
Authors: Zepeda-Gurrola Reyna C. , Vázquez-Marrufo Gerardo , Guo Xianwu , Rodríguez-Luna Isabel C. , Sánchez-Varela Alejandro , Vázquez-Garcidueñas Ma. Soledad
Published: September 2021

Background:

Salmonella enterica is the etiological agent of salmonellosis, with a high
infection rate worldwide in Mexico, ST213 genotype of S. enterica ser. Typhimurium is displacing
the ancestral ST19 genotype. Bacterial cytoskeleton protein complex MreBCD plays an important
role in S. enterica pathogenesis, but underlying mechanisms are unknown.

Results:

In this study, 106 interactions among MreBCD and 15 proteins from S. Typhimurium
Pathogenicity Islands 1 (SP-I) and 2 (SP-2) involved in both bacterial virulence and stress response
were predicted in ST213 and ST19 genotypes, of which 12 interactions were confirmed in vitro. In
addition, gene cluster analysis in 100 S. Typhimurium genomes was performed for these genes.

Results and Conclusion:

The in silico and in vitro results showed a novel MreBCD interactome involved
in regulating pathogenesis and stress response through interactions with virulence factors located
at SPI-1 and SPI-2. Furthermore, both pseudogene presence and sequence variations in four
tested proteins between genotypes resulted in differential interaction patterns involved in Salmonella
motility and survival in eukaryotic cells, which could explain the replacement of ST19 by
ST213 in Mexico.
Characterization, ACE Inhibitory and Antioxidative Properties of Peptide
Fractions Obtained from White Shrimp (Litopenaeus vannamei)
Authors: Latorres Juliana , Wasielesky Wilson , Prentice Carlos
Published: September 2021

Background:

Aquatic organisms are considered to be an important source of bioactive
peptides with a high antioxidant and antihypertensive capacity. Therefore, the objective of this
study was to hydrolyse peptide fractions from white shrimp (Litopenaeus vannamei) muscle by Alcalase
and Protamex and to evaluate the angiotensin I-converting enzyme (ACE) inhibitory and the
antioxidant activities.

Methods:

Protein hydrolysates of White shrimp were obtained by enzymatic hydrolysis using Alcalase
and Protamex until the degree of hydrolysis reached 10% and 20%. Peptide fractions were
obtained from White shrimp protein hydrolysates by ultrafiltration using membranes with sizes of
10 and 3 kDa. The antioxidant activity was evaluated for the three peptide fractions (F1: >10 kDa,
F2: 3-10 kDa and F3: <3 kDa). To measure the antihypertensive activity, fractions with molecular
sizes of less than 3 kDa were used.

Results:

The fractions obtained with Alcalase showed greater inhibitory effects on the ACE. In general,
the molecular weight of the fractions influenced the antioxidant activity, with fractions smaller
than 3 kDa having a high capacity for sequestering the DPPH radical, while peptide fractions
with a size greater than 10 kDa presented higher reducing power. However, in capturing the ABTS
radical, a high antioxidant capacity was observed for both fractions.

Conclusion:

The results suggest white shrimp would be an attractive raw material for the manufacture
of antioxidant and anti-hypertensive nutraceutical ingredients.

Review
Authors: Jalili Mahsa , Nourmohammadi Hassan , Sayehmiri Kourosh
Published: September 2021

Background:

Previous studies suggested an association between Chlamydia pneumoniae
and Mycoplasma pneumonia with atherosclerosis, separately. Until now, according to inconsistent
information, the relationship between C.pneumoniae and M.pneumoniae with atherosclerosis is controversial.

Objective:

The aim of this study is to investigate the association between C.pneumoniae and
M.pneumoniae as two separate risk factors with atherosclerosis through systematic review and metaanalysis
study.

Methods:

We searched databases, such as Pubmed, SID, Magiran, Google scholar and Iranmedex,
using the following keywords in English and Persian language: C. pneumoniae, M. pneumoniae, and
atherosclerosis. Data were analyzed with meta-analysis and a random effect model. Also, in this study,
heterogeneity of articles was estimated by using the I2 index. Finally, the data were analyzed with
STAT (version 11.2).

Results:

Among thirty-eight articles for C. pneumoniae and five articles for M. pneumoniae individually
reviewed that included 2980 samples for M. pneumoniae and 23298 samples for C. pneumoniae,
the result demonstrated that the association between M. pneumoniae and C. pneumoniae with atherosclerosis
is significant with OR (odds ratio) = 1.58 (95% Confidence Interval (CI): 1.00 to 2.50), OR
(odds ratio) = 2.25 (95% Confidence Interval (CI): 1.91 to 2.64), respectively.

Conclusion:

This systematic review study provides strong evidence for the role of persistent bacterial
infections, such as M. pneumoniae and C. pneumoniae, in potential atherosclerosis. Thus, a novel way
should be employed for the complete management of bacterial infection.

Published: September 2021

Introduction:

Along with massive developments in various aspects of life, mental health is one of the issues that must be discussed to encourage optimal development of an individual. To achieve these goals, we need an instrument that can measure and determine the mental health needs of humans precisely.

Materials and Methods:

The study was conducted using a cross-sectional method with a quantitative research design. Participants in this study were adolescent students from Indonesia and Malaysia. The American Mental Health Screening Tool adapted to Indonesian and Malaysian conditions is used as an instrument to measure mental health. There were 359 people from Indonesia and 171 people from Malaysia participating in this study. This type of parameter needs to be identified by the category coefficient of the RASCH scoring function model for polycotomic responses.

Results and Discussion:

The results showed that the American Screening Tools Mental Health instrument had a unidimensionality value below 15%, which means that the variables on the instrument were able to describe mental health. A total of 4 items were invalid so only 59 items could be used to measure mental health. Cronbach alpha value, which is 0.71 indicates that the instrument has good reliability. The average ability of participants from Indonesia and Malaysia was in the moderate category, but 39 participants from Malaysia and 18 participants from Indonesia gave answers that did not match their ability

Conclusion:

The screening tool instrument is able to describe the variables about mental health. These instruments tend to only describe the mental health of participants who fall into the medium and high categories.

Doğu Anadolu Fay Zonu uzanımının tartışma konusu olduğu Kilikya Havzasında 27 Haziran 1998 yılında orta büyüklükte (Mw=6.2) bir deprem meydana gelmiştir. Çalışmada depremin kaynak parametreleri belirlenmesi amacıyla deprem kaynağı nokta-kaynak ters çözüm yöntemi telesismik P ve SH dalga şekilleri kullanılarak yapılmıştır. Nokta-kaynak modellemesinde gözlenmiş-kuramsal dalga şekilleri arasında yaklaşık olarak aynı derecede uyum gözlenmiştir. Böylece tek alt olaylı bir kırılma süreci nokta kaynak gösteriminde depremin kırılma süreci olarak kabul edilmiştir. Aynı zamanda nokta kaynak modellemesi denemeleri 24 km’ de kaynak lokasyonuyla derin alt kabukta bir kırılmayı gerektirmektedir. Kaynak mekanizması çözümünde KD-GB yönelimli (doğrultu=57o, eğim=70o ve kayma açısı=20o) düğüm düzlemi fay düzlemi olarak belirlenmiştir ve yakındaki Göksu fay zonuyla paralellikten sapmış bir görüntü vermiştir. Nokta kaynak modeli için sismik moment 2.24X1018 Nm (Mw=6.2) olarak hesaplanmıştır. Telesismik modelleme sonuçları bir bütün olarak deprem kırılmasının Göksu Fay Zonu (GFZ)’ nun yeryüzüne ulaşmayan, GD eğimli ve GFZ’ nin yüzeydeki haritalanmış izinden farklı doğrultulu bir dalı üzerinde gerçekleştiğini önermektedir.

Zeytin (Olea europaea L.) yaprağı içerdiği önemli fenolik bileşikleri ve sergilediği çeşitli fonksiyonel ve terapötik özellikleri ile dikkat çekmektedir. Zeytinyağı üretiminde meyvelerin hasadı sırasında açığa çıkan bu yan ürün hasat edilen meyvelerin yaklaşık %10’ unu oluşturmakta ve bu değerli yan üründen faydalanılamamaktadır. Bu çalışmada zeytin yaprağı ekstraktının klasik ekstraksiyon yöntemi ile elde edilerek püskürtmeli kurutucuda zeytin yaprağı ekstraktı tozuna (ZYET) dönüştürülmesi ve bu ürünün soğuk çay formülasyonunda değerlendirilmesi amaçlanmıştır. Zeytin yaprağı ekstraktı içerdiği oleuropeinden kaynaklı çok güçlü bir acılık algısına neden olduğundan dolayı gıda formülasyonlarında sınırlı miktarda kullanılabilmektedir. Bu nedenle acı tadın baskılanması ve duyusal olarak kabul edilebilir soğuk çayın geliştirilmesi hedefiyle elde edilen zeytin yaprağı ekstraktı püskürtmeli kurutucu ile maltodekstrin eşliğinde kaplanmıştır. Buna ek olarak, ZYET, sakaroz ve sitrik asit ile 8 farklı formülasyonda üretilen soğuk çayların bazı fizikokimyasal özellikleri ve duyusal kabul edilebilirlikleri üzerine ZYET ve sakaroz miktarının etkisi araştırılmıştır. Soğuk çayların briks değerleri %6.87-9.45 ve toplam fenolik madde miktarları 12.46-21.76 mg GAE/100 mL olarak tespit edilirken, %0.10 ZYET, %9 sakaroz ve %0.15 sitrik asit içeren soğuk çay örneğinin duyusal olarak en çok beğenilen grup olduğu tespit edilmiştir. Ucuz bir kaynak olarak kullanılabilme potansiyeline sahip olan bu artık ürünün farklı gıda formülasyonlarında değerlendirilerek endüstriye kazandırılması gerektiği düşünülmektedir.

A Comparison of the Use of Smart Devices, Apps, and Social Media Between Adults With and Without Hearing Impairment: Cross-sectional Web-Based Study
Authors: van Wier Marieke F , Urry Emily , Lissenberg-Witte Birgit I , Kramer Sophia E
Published: September 2021

Background

eHealth and social media could be of particular benefit to adults with hearing impairment, but it is unknown whether their use of smart devices, apps, and social media is similar to that of the general population.

Objective

Our aim is to study whether adults with normal hearing and those with impaired hearing differ in their weekly use of smart devices, apps, and social media; reasons for using social media; and benefits from using social media.

Methods

We used data from a Dutch cohort, the National Longitudinal Study on Hearing. Data were collected from September 2016 to April 2020 using a web-based questionnaire and speech-in-noise test. The results from this test were used to categorize normal hearing and hearing impairment. Outcomes were compared using (multiple) logistic regression models.

Results

Adults with impaired hearing (n=384) did not differ from normal hearing adults (n=341) in their use of a smartphone or tablet. They were less likely to make use of social media apps on a smartphone, tablet, or smartwatch (age-adjusted odds ratio [OR] 0.67, 95% CI 0.48-0.92; P=.02). Use of social media on all devices and use of other apps did not differ. Adults with hearing impairment were more likely to agree with using social media to stay in touch with family members (OR 1.54, 95% CI 1.16-2.07; P=.003) and friends (age-adjusted OR 1.35, 95% CI 1.01-1.81; P=.046). Furthermore, they were more likely to agree with using social media to perform their work (age-adjusted OR 1.51, 95% CI 1.04-2.18; P=.03). There were no differences in the experienced benefits from social media.

Conclusions

The potential for eHealth is confirmed because adults with hearing impairment are not less likely to use smart devices than their normal hearing peers. Adults with hearing impairment are less likely to use social media apps on a smart device but not less likely to use social media on all types of internet-connected devices. This warrants further research on the types of social media platforms that adults with hearing impairment use and on the type of device on which they prefer to use social media. Given that participants with hearing impairment are more likely than their normal hearing peers to use social media to perform their work, use of social media may be seen as an opportunity to enhance vocational rehabilitation services for persons with hearing impairment.

Authors: Hou Xinyao , Zhang Yu , Wang Yanping , Wang Xinyi , Zhao Jiahao , Zhu Xiaobo , Su Jianbo
Published: September 2021

Background

Masked face is a characteristic clinical manifestation of Parkinson disease (PD), but subjective evaluations from different clinicians often show low consistency owing to a lack of accurate detection technology. Hence, it is of great significance to develop methods to make monitoring easier and more accessible.

Objective

The study aimed to develop a markerless 2D video, facial feature recognition–based, artificial intelligence (AI) model to assess facial features of PD patients and investigate how AI could help neurologists improve the performance of early PD diagnosis.

Methods

We collected 140 videos of facial expressions from 70 PD patients and 70 matched controls from 3 hospitals using a single 2D video camera. We developed and tested an AI model that performs masked face recognition of PD patients based on the acquisition and evaluation of facial features including geometric and texture features. Random forest, support vector machines, and k-nearest neighbor were used to train the model. The diagnostic performance of the AI model was compared with that of 5 neurologists.

Results

The experimental results showed that our AI models can achieve feasible and effective facial feature recognition ability to assist with PD diagnosis. The accuracy of PD diagnosis can reach 83% using geometric features. And with the model trained by random forest, the accuracy of texture features is up to 86%. When these 2 features are combined, an F1 value of 88% can be reached, where the random forest algorithm is used. Further, the facial features of patients with PD were not associated with the motor and nonmotor symptoms of PD.

Conclusions

PD patients commonly exhibit masked facial features. Videos of a facial feature recognition–based AI model can provide a valuable tool to assist with PD diagnosis and the potential of realizing remote monitoring of the patient’s condition, especially during the COVID-19 pandemic.

Published: September 2021

Background

Since the end of 2019, COVID-19 has had a significant impact on people around the globe. As governments institute more restrictive measures, public adherence could decrease and discontent may grow. Providing high-quality information and countering fake news are important. However, we also need feedback loops so that government officials can refine preventive measures and communication strategies. Policy makers need information—preferably based on real-time data—on people’s cognitive, emotional, and behavioral reactions to public health messages and restrictive measures. PubliCo aims to foster effective and tailored risk and crisis communication as well as provide an assessment of the risks and benefits of prevention and control measures, since their effectiveness depends on public trust and cooperation.

Objective

Our project aims to develop a tool that helps tackle the COVID-19 infodemic, with a focus on enabling a nuanced and in-depth understanding of public perception. The project adopts a transdisciplinary multistakeholder approach, including participatory citizen science.

Methods

We aim to combine a literature and media review and analysis as well as empirical research using mixed methods, including an online survey and diary-based research, both of which are ongoing and continuously updated. Building on real-time data and continuous data collection, our research results will be highly adaptable to the evolving situation.

Results

As of September 2021, two-thirds of the proposed tool is operational. The current development cycles are focusing on analytics, user experience, and interface refinement. We have collected a total of 473 responses through PubliCo Survey and 22 diaries through PubliCo Diaries.

Conclusions

Pilot data show that PubliCo is a promising and efficient concept for bidirectional risk and crisis communication in the context of public health crises. Further data are needed to assess its function at a larger scale or in the context of an issue other than COVID-19.

Effectiveness of Text Messaging Interventions on Blood Pressure Control Among Patients With Hypertension: Systematic Review of Randomized Controlled Trials (Preprint)
Authors: Tam Hon Lon , Wong Eliza Mi Ling , Cheung Kin , Chung Siu Fung
Published: September 2021

BACKGROUND

Controlling blood pressure (BP) is an international health concern, and high BP is a major contributor to cardiovascular disease mortality. Evidence has shown that educational interventions directed at patients potentially improve BP control and adherence to medications and lifestyle modifications. In addition, a text messaging intervention has a potential effect on BP control; however, the dosage of a text messaging intervention has not been determined in previous reviews, resulting in difficult application in practice.

OBJECTIVE

This review aimed to identify the effectiveness of a text messaging intervention on hypertension management with a specific focus on the dosage of text messaging and the type of additional interventions with text messaging.

METHODS

A systematic review was conducted and reported on in accordance with PRISMA guideline. Participants were aged 18 years and older and diagnosed with primary hypertension. The included studies used text messaging as a component of the intervention. We searched for randomized controlled trials published until June 30, 2020, from the following health-related electronic databases: Embase, Medline, CINAHL Complete, PsycINFO, and Scopus. Data were extracted for qualitative synthesis and meta-analysis. The Physiotherapy Evidence Database Scale was used to assess the methodological quality of each study, and the quality of the included studies was assessed independently by two authors.

RESULTS

Twelve studies met the inclusion criteria. The overall methodological quality was fair (mean score 5.75). The frequency of text message delivery varied from daily to biweekly. Health education was identified in 4 studies as an additional intervention with text messaging. The overall results showed that the text messaging intervention significantly reduced systolic BP (SBP) but not diastolic BP (DBP). There was no significant difference in BP reduction between studies that lasted 6 months or less and those that lasted more than 7 months. Seven studies that lasted 6 months or less involving 1428 patients with hypertension were pooled for further meta-analysis. Text messages delivered at a lower frequency (once per week or less) had a small effect on SBP reduction (effect size 0.35, P<.01) and DBP reduction (effect size 0.28, P=.01). In addition, the use of a text messaging intervention halved the odds of uncontrolled BP among patients with hypertension in 6 months (odds ratio 0.46, P=.02).

CONCLUSIONS

This review found that a text messaging intervention was effective in BP control. One-way text messaging delivered in a weekly manner was suggested to be effective and required fewer resources. Future studies should use different forms of text message and be integrated into other interventions to improve adherence behaviors and BP control among patients with hypertension.
A Web-Based Integrated Management Program for Improving Medication Adherence and Quality of Life, and Reducing Readmission in Patients With Atrial Fibrillation: Randomized Controlled Trial (Preprint)
Authors: Hsieh Hui-Ling , Kao Chi-Wen , Cheng Shu-Meng , Chang Yue-Cune
Published: September 2021

BACKGROUND

Atrial fibrillation (AF) is related to a variety of chronic diseases and life-threatening complications. It is estimated that by 2050, there will be 72 million patients with AF in Asia, of which 2.9 million will have AF-associated stroke. AF has become a major issue for health care systems.

OBJECTIVE

We aimed to evaluate the effects of a web-based integrated management program on improving coping strategies, medication adherence, and health-related quality of life (HRQoL) in patients with AF, and to detect the effect on decreasing readmission events.

METHODS

The parallel-group, single-blind, prospective randomized controlled trial recruited patients with AF from a medical center in northern Taiwan and divided them randomly into intervention and control groups. Patients in the intervention group received the web-based integrated management program, whereas those in the control group received usual care. The measurement tools included the Brief Coping Orientation to Problems Experienced (COPE) scale, Medication Adherence Rating Scale (MARS), the three-level version of the EuroQoL five-dimension self-report questionnaire (EQ-5D-3L), and readmission events 2 years after initiating the intervention. Data were collected at 4 instances (baseline, 1 month, 3 months, and 6 months after initiating the intervention), and analyzed with generalized estimating equations (GEEs).

RESULTS

A total of 231 patients were recruited and allocated into an intervention (n=115) or control (n=116) group. The mean age of participants was 73.08 (SD 11.71) years. Most participants were diagnosed with paroxysmal AF (171/231, 74%), and the most frequent comorbidity was hypertension (162/231, 70.1%). Compared with the control group, the intervention group showed significantly greater improvement in approach coping strategies, medication adherence, and HRQoL at 1, 3, and 6 months (all P<.05). In addition, the intervention group showed significantly fewer readmission events within 2 years (OR 0.406, P=.03), compared with the control group.

CONCLUSIONS

The web-based integrated management program can significantly improve patients' coping strategy and medication adherence. Therefore, it can empower patients to maintain disease stability, which is a major factor in improving their HRQoL and reducing readmission events within 2 years.

IoT Based Smart Shopping Cart
Authors: A Adhithya.
Published: September 2021

Abstract: Physically challenged and senior citizens find it difficult to push heavily loaded carts around the supermarket. To combat this, we have implemented an autonomous shopping cart that supersedes the existing shopping trolley. This autonomous cart can manoeuvre around without the need of pushing it by using multiple ultrasonic sensors. To avoid long queues at the billing counters and also to reduce the workload of the employees at the supermarket, we have implemented a billing system. Scanning is incorporated in the cart itself, thus reducing the time wasted by customers at the billing counter. This billing system uses RFID (Radio Frequency Identification) to scan products. Products scanned in the cart are sent to the computers installed in the supermarket using a Wi-Fi module. The Automated Shopping Cart thereby eases the shopping experience of customers and reduces the manpower employed in supermarkets. The significant benefit of using an automated cart is that customers can move swiftly through the cash counter and check out independently.

Authors:   Institute of the Lithuanian Language, Chistiakova Marina V.
Published: September 2021

In the 1980s E. Fet discovered the Pskov edition of the Prologue, dating back to the middle of the 15th century and preserved in the copies of the autumn-winter half-year. The researcher noticed its unusual didactic section, containing newly included readings. This article discusses the sources of individual (not typical for other editions of the Prologue) sermons of the Pskov edition for September — November. Research has found that the closest source of the main part of borrowings is the Saratov edition of Zlatostruy (Chrysorrhoas Collection) known in the copy of the end of the 15th century. The body of this article provides arguments in favour of working with this source as well as information on the use of some other reading collections. The annex contains lists of identified sermons.
