Transformation of a Modern Schoolstudent’s Language Personality in a Context of Digitalization of Society
Authors:   Transbaikal State University, Natalya V. Vasilyeva
Published: December 2022

Nowadays, studying of changes that have occurred in the language personality of modern schoolchildren under the influence of factors caused by the digitalization of society is relevant. These changes are noted by scientists in various scientific fields, but the results of their studies are not sufficiently taken into account in teaching Russian. This article aims at identifying factors affecting the transformation of a modern student’s language personality and describing the nature of changes taking place in the language personality. Analysis and generalization of scientific literature on research problem made it possible to state a significant impact of electronic discourse and electronic hypertext on the language personality of a modern student. The author draws a conclusion that excessive involvement of students in virtual communication, as well as lack of training in working with electronic hypertext, on the one hand, leads to difficulties in non-virtual communication, and on the other, to the formation of clip thinking. The author also revealed changes that affected verbalsemantic, thesaurus and pragmatic levels of the language personality. The results obtained show that modern schoolchildren have assimilated lexical, word-forming, grammatical means, values, patterns of behavior of electronic discourse. The basic needs of the modern language personality include acceptance and recognition by the network community, communication in virtual space. Individual values formed under the influence of electronic discourse and electronic hypertext are democracy, freedom of expression, anonymity, unlimited access to information, tertiary socialization, inculturation, and self-presentation. The behavior models learned by a modern student in the context of society digitalization demonstrate a high degree of emotionality, polarity of behavior, familiarity and permissiveness. The author assumes that application of the research findings in the practice of teaching Russian to schoolchildren will specify the goals of education, as well as formation of students’ abilities to deal with information, to perform communicative activities in various fields and communication situations. Keywords: language personality, network language personality, virtual language personality, electronic discourse, electronic hypertext, schoolstudent, teaching Russian

Published: December 2022

A atividade mineradora consiste na pesquisa, exploração, lavra e beneficiamento de minérios presentes no subsolo, contudo, é responsável por grande impacto ambiental devido, principalmente, ao descarte indiscriminado de resíduos. A região do Cariri localizado no interior do Ceará é considerada um importante polo mineral devido à presença de jazidas de calcário laminado, mais conhecido como Pedra Cariri, que são encontradas no município de Nova Olinda. A extração da Pedra Cariri vem crescendo ao longo dos anos e é realizada a céu aberto, em condições rudimentares, gerando considerável volume de resíduos. Este trabalho consiste em uma pesquisa experimental e tem por objetivo apresentar resultados de resistência à compressão simples com a utilização do rejeito da mineração do calcário laminado na produção de tijolos cerâmicos de resíduo-cimento, contribuindo como uma alternativa inovadora e sustentável no ramo da construção civil, visto que além de reduzir o descarte do resíduo no meio ambiente, dispensam o processo de queima e minimizam os custos com materiais e mão de obra, devido ser modulares podendo servir de decoração ao ambiente e facilitando as instalações elétricas e hidráulicas, além da possibilidade de produção próxima à obra. Para este trabalho os materiais utilizados tiveram diâmetros iguais ou inferiores a 2,0 mm e os tijolos foram produzidos com quatro composições granulométricas diferentes, a fim de avaliar a influência da granulometria do resíduo na resistência à compressão simples dos tijolos de resíduo-cimento.

Cilj istraživanja bio je utvrditi izraženost stresa, anksioznosti i depresivnosti u zdravstvenih djelatnika tijekom pandemije bolesti COVID-19, čimbenike koji predviđaju njihov intenzitet te stresnost različitih situacija u radnom i obiteljskom okruženju. Primijenjeni su DASS, Brief RCOPE i CD-RISC-10. Istraživanje je provedeno online tijekom svibnja i lipnja 2020. na 135 sudionika metodom snježne grude. Dobiveni rezultati pokazuju višu izraženost stresa i anksioznosti, te podjednaku razinu depresivnosti kao i u istraživanju provedenom u SAD-u na nekliničkom uzorku. Otpornost je negativno povezana sa stresom, anksioznosti i depresivnosti, a negativno religijsko suočavanje je pozitivno povezano s depresivnosti. Također, žene pokazuju niže razine depresivnosti od muških sudionika. Što se tiče situacija u radnom okruženju, zdravstveni djelatnici podjednako brinu o tome je li njihova zaštitna oprema neprimjerena, hoće li imati dovoljno djelatnika na raspolaganju te hoće li se netko od njihovih kolega razboljeti. Nešto manje brinu o tome da je njihovo vlastito zdravlje ugroženo i jesu li zaštitnu opremu upotrebljavali na adekvatan način. Što se tiče situacija u obiteljskom okruženju, najviše brige izaziva pomisao da zbog svojeg posla članove svoje obitelji izlaže riziku zaraze; slijedi briga zbog mogućnosti samoizolacije, dok je briga zbog promjena u ponašanju koje mogu utjecati na kvalitetu bliskih odnosa na posljednjem mjestu. Sudionici u direktnom kontaktu s oboljelima više brinu o tome da neće imati dovoljno djelatnika na raspolaganju i da je njihovo zdravlje ugroženo. Sudionici koji su bili u kontaktu s COVID-19 pacijentima i kolegama kojima je kasnije dijagnosticiran COVID-19 više brinu da neće imati dovoljno djelatnika na raspolaganju i da će se netko od kolega razboljeti. Samci su više zabrinuti zbog neprimjerenosti zaštitne opreme od onih koji žive sa suprugom ili u izvanbračnoj vezi. Ključne riječi: COVID-19, stres, anksioznost, depresivnost, otpornost, religijsko suočavanje
Intenzivno igranje videoigara – patološki oblik ovisnosti ili indikator procesa izgradnje društvene (i profesionalne) karijere
Authors:   Sveučilište u Zadru, Odjel za sociologiju, Obala kralja Petra Krešimira IV 2, 23000 Zadar, Krolo Krešimir
Published: December 2022

Tema ovog rada je analiza relevantnosti teorija i perspektiva mjerenja ovisnosti o videoigrama unutar širih sociokulturnih okvira. S ciljem dodatnog razvoja postojeće metodologije korištene su sociološke perspektive (Crawford, 2011) razumijevanja gaminga kao zasebne kulture unutar koje postoje osnove za izgradnju društvene i profesionalne karijere. Analizom podataka prikupljenih u sklopu šireg istraživanja „Sociokulturni profil videoigrača i igračica u Hrvatskoj“, ustanovljeno je kako postoje dva temeljna podskupa ovisnosti (ovisnost usmjerena prema sebi i društvena dimenzija ovisnosti) od kojih je faktor ovisnosti usmjerene prema sebi objašnjen prediktorima samoidentifikacije s gamerskom kulturom, željom za radom u izradi videoigara i općenitim praćenjem gaming scene. Drugi faktor ovisnosti objašnjen je prvenstveno sociodemografskim varijablama (dob, zadovoljstvo životom i uključenost u obrazovni proces). Zaključna razmatranja upućuju na razumijevanje ovisnosti o videoigrama unutar širih sociokulturnih parametara karakterističnih za globalni digitalno-interaktivni kontekst kako bi se klinička ovisnost o videoigrama mogla preciznije odvojiti od kompulzivnog igranja kao procesa izgradnje društvene i profesionalne karijere.

Published: December 2022

Health is that state in which the structure and function of a particular individual is operating optimally and the individual is in a state of physical, mental, and spiritual equilibrium. Disease is a state of inequilibrium of the doshas, dhatus, agnis, and malas the individual is out of harmonyboth internally and with relation to the environment and experiences unpleasant sensations and misery in some form (duhkya). Vata governs all movement in the mind and body. It controls blood flow, elimination of wastes, breathing and the movement of thoughts across the mind.Since Pitta and Kapha cannot move without it, Vata is considered the leader of the three Ayurvedic Principles in the body. Its very important to keep Vata in good balance.Basti karma is the most powerful of the five main procedures of Panchkarma,as Acharya Charaka has considered Basti as Ardha Chikitsa taking into account that in case of vitiated Vata dosha and Vata is the controller of all other Doshas, Dushyas, Malas and their functioning.
Russell y la Elegía de Gray
Authors: Fernández de Castro Max , Espinoza Rosa María
Published: December 2022

El pasaje de la Elegía de Gray (PEG) en “On Denoting” es extremadamente obscuro y ha sido objeto de muy diversas interpretaciones. Aparentemente contiene una crítica devastadora contra la teoría de los conceptos denotativos que el propio Russell había postulado en The Principles of Mathematics (PM) (1903). En este artículo exponemos sucintamente dicha teoría semántica, examinamos detalladamente el pasaje en cuestión y exploramos algunas de las interpretaciones que pretenden desentrañar su sentido. Con ello mostramos, en primer lugar, que la crítica se dirige directamente contra la teoría de PM; en segundo lugar, que no es posible hacer unos pocos cambios homogéneos para habilitar una lectura literal del pasaje; finalmente, que, si bien algunos de los argumentos que los intérpretes han aducido para abandonar la teoría de los conceptos denotativos son sólidos, no es obvio que todos ellos se encuentren en PEG.
La injusticia de Pier della Vigna (Inferno, XIII, 72). ¿El suicida es injusto consigo mismo?
Authors: Leyva Ricardo
Published: December 2022

En el canto XIII del Inferno, en el bosque de los suicidas, Pier della Vigna dice que, al momento de su muerte, él, que era justo, se volvió injusto contra sí mismo. Esta afirmación da lugar a la pregunta de si el suicida puede ser injusto consigo mismo y cómo Dante puede afirmarlo. En este artículo, se investiga esto desde: 1) la caracterización de la justicia en el tratado filosófico de Dante, Convivio, 2) algunos pasajes del Purgatorio en los que Dante desarrolla su teoría de la acción, y 3) un pasaje de la Ética nicomáquea de Aristóteles en el que se cuestiona si el suicida es injusto consigo mismo.
De un ocuparse de las circunstancias. El sentido del cuidado (Sorge) en la obra de Martin Heidegger Der Begriff der Zeit (1924)
Authors: Gilabert Fernando
Published: December 2022

El existenciario del cuidado (Sorge) es uno de los elementos de mayor importancia en el entramado filosófico de Martin Heidegger. El cometido de mi trabajo es profundizar en la relación que tiene ese existenciario con otros tres que consideramos fundamentales: ser-en-el-mundo (In-der-Welt-sein), ser-con (Mit-sein) y el Uno impersonal (das Man). Una panorámica propedéutica de la relación con ellos puede elucidarse a partir de la conferencia que Heidegger impartió en Marburgo en 1924: Der Begriff der Zeit, uno de los textos clave de los que allanan el camino a Sein und Zeit, considerada su obra magna.
Panteísmo militante. Hegel como significante político en la narrativa marxiana
Authors: Narváez Angelo Antonio
Published: December 2022

En este artículo abordo el problema del contexto político, ideológico y filosófico como trasfondo de las referencias lingüísticas de Karl Marx a la filosofía hegeliana, especialmente en virtud del célebre epílogo a la segunda edición alemana de El capital. Lo que sostengo es que, además de la ya compleja relación lógica entre la filosofía hegeliana y la crítica marxiana de la economía política, las referencias a Hegel en la narrativa marxiana refieren también a una dimensión simbólica propia de las disputas previas y posteriores al Vormärz, en las que se cruzan los conflictos teológicos y políticos como horizonte de afirmación o negación de la realidad social de la época.
Effect of Statins on the Blood Lipid Profile in Patients with Different
Cardiovascular Diseases: A Systematic Review with Meta-analysis of
Randomized Clinical Trials
Authors: Aslani Saeed , Razi Bahman , Imani Danyal , Mohammadi Keyhan , Jamialahmadi Tannaz , Reiner Željko , Sahebkar Amirhossein
Published: December 2022

Background:

Statins are the main lipid-lowering drugs and are used in the prevention
of cardiovascular diseases (CVDs). Since the results have been, to some extent,
inconsistent in the clinical trials concerning different types of CVDs, a systematic review
and meta-analysis was performed to prove the effect of statins on decreasing elevated levels
of total cholesterol, triglycerides (TG), low-density lipoprotein cholesterol (LDL-C),
and high-density lipoprotein cholesterol (HDL-C) in patients with CVDs.

Methods:

Literature search was performed on major electronic databases (MEDLINE/
PubMed, Scopus, and ISI Web of Science) from inception up to July 2021 to find
randomized controlled trials (RCTs) evaluating the effect of different statins on different
types of CVDs. The effect size was determined using weighted mean difference (WMD)
and corresponding 95% confidence interval (CI).

Results:

Statin therapy significantly decreased levels of total cholesterol (WMD = -33.37
mg/dl, 95% CI: -45.98 to -20.76, P<0.001), LDL-C (WMD = -29.42 mg/dl, 95% CI:
-36.81 to -22.03, P<0.001), and TG (WMD = -15.19 mg/dl, 95% CI = -26.41 to -3.97,
P<0.001), and increased levels of HDL-C (WMD = 1.55 mg/dl, 95% CI: 0.20, to 2.90,
P=0.02) in patients with different CVDs.

Conclusion:

Statin therapy was found effective in lowering levels of total cholesterol,
LDL-C, and TG, and increasing levels of HDL-C in patients with different CVDs.
Quercetin Protected from Aluminum Phosphide-induced Acute and Subacute
Cardio- and Hepatotoxicity in Rats
Authors: Malekinejad Hassan , Jafari-Garageshlaghi Fatemeh , Hashtarkhani Fatemeh , Soraya Hamid
Published: December 2022

Background:

Aluminum phosphide (ALP) intoxication either accidentally or intentionally, is one of the major health concerns in developing countries. Its poisoning causes severe damage to organs including the heart and liver.

Objectives:

This study aimed to investigate the hepato- and cardioprotective effects of quercetin (QCN) on the acute/subacute toxicity of ALP in rodent models.

Methods:

Acute (single dose, 12.5 mg/kg, orally) and subacute (2 mg/kg, orally and 7 days) intoxication of ALP were induced in rats and the protective effects of QCN on altered hepatic/cardiac functional enzyme concentrations, myeloperoxidase activity, oxidative stress biomarkers, and histopathological changes were studied at three doses of 10, 50 and 100 mg/kg BW. To record any heart abnormality, an electrocardiogram (ECG) was recorded 3 h after the last treatment.

Results:

Quercetin reduced the ALP-increased hepatic and cardiac functional enzyme concentrations and myeloperoxidase activity. Moreover, QCN improved remarkably the ALP-induced ECG abnormalities (T inversion, bigeminy in R waves) and arrhythmias. QCN attenuated significantly (p<0.05) the ALP-induced oxidative/nitrosative stress and histopathological injuries in the liver and heart.

Conclusion:

Our results suggest that QCN is able to protect the ALP-induced cardiac and hepatic injuries in both acute and subacute models and its effects attribute to its antioxidant and anti-inflammatory properties.
Insight into the Various Approaches for the Enhancement of Bioavailability
and Pharmacological Potency of Terpenoids: A Review
Authors: Majee Chandana , Atriya Anmol , Mazumder Rupa , Choudhary Alka N. , Salahuddin  , Mazumder Avijit , Dahiya Aman , Priya Neha
Published: December 2022

Terpenoids are naturally occurring secondary metabolites that consist of isoprene units
(i.e., 2-methyl-1,3-butadiene). Terpenoids became recognized because of their diverse pharmacological
benefits, such as anti-cancer, anti-inflammatory, antioxidant, analgesic, antibacterial, antifungal,
hepatoprotective, antiviral, and antiparasitic activities. But most of these compounds have limited
lipophilicity, dissolution rate, aqueous solubility, and drug permeability, so they are not used effectively.
The low bioavailability significantly interferes with the performance of terpenoids to cure
diseases, and the absorption process of terpenoids also becomes disrupted; therefore, their bioavailability
in the blood becomes insufficient to achieve optimal treatment activity. Thus, to overcome
this limitation, some strategies are used, such as nanotechnology (nanoparticles, carrier complexation),
cocrystal, and glycosylation. Thus, this review summarizes the chemistry of terpenoids, factors
that limit the bioavailability of terpenoids, and strategies employed to date with their design
principles and outcomes possibly increasing their bioactivity.

By COVID-19 in Peruvian Women
Authors: Valverde-Espinoza Natalia , Santos-Rosales Yuly , Barja-Ore John , Leon-Pastuso Pamela
Published: December 2022

Background:

The covid-19 pandemic affected family planning management and the sexual
and reproductive rights of couples.

Objective:

To determine the factors associated with the interruption of the use of contraceptive methods
during the quarantine by COVID-19 in Peruvian women.

Methods:

Analytical and cross-sectional study, which included 342 women who used a contraceptive
method before the COVID-19 quarantine, to whom a virtual questionnaire disseminated on social
networks was applied. Pearson's chi-square evaluated associations between method discontinuation
and the factors studied.

Results:

Of the total number of women, 45% discontinued the use of contraceptive methods during the
COVID-19 quarantine. The predominant age range was from 18 to 34 years (93.9%). The factors
associated with this interruption were age (p = 0.044), marital status (p < 0.001), parity (p < 0.001),
sexual relations (p < 0.001), and searching for information by digital means (p = 0.044). The main
reason for stopping use was fear of contagion by COVID-19 (42.8%).

Conclusion:

About half of contraceptive method users interrupted their use during the COVID-19
quarantine, and the factors associated with said interruption were personal, reproductive, and informational.
Therefore, health personnel must provide comprehensive care for women, especially in health
emergencies.

Published: December 2022

The development of single-cell RNA sequencing (scRNA-seq) technology provides an
excellent opportunity to explore cell heterogeneity and diversity. With the growing application of
scRNA-seq data, many computational clustering methods have been developed to further uncover
cell subgroups, and cell dynamics at the group level. Due to the characteristics of high dimension,
high sparsity and high noise of the scRNA-seq data, it is challenging to use traditional clustering
methods. Fortunately, deep learning technologies characterize the properties of scRNA-seq data well
and provide a new perspective for data analysis. This work reviews the most popular computational
clustering methods and tools based on deep learning technologies, involving comparison, data collection,
code acquisition, results evaluation, and so on. In general, such a presentation points out some
progress and limitations of the existing methods and discusses the challenges and directions for further
research, which may give new insight to address a broader range of new challenges in dealing
with single-cell sequencing data and downstream analysis.
Colonic Degradation as Reverse Process to Flavone Biosynthesis in Plants:
Similarities and Differences
Authors: Sak Katrin
Published: December 2022

Background:

For many years, it was thought that the main function of the colon is the
reabsorption of water and salt and the elimination of unused food materials. Only very recently, a
crucial role of the human intestinal microbiota in the metabolism of different food constituents,
including plant foods-derived flavonoids, was discovered. Currently, the knowledge about colonic
degradation of ingested flavonoids, involved bacteria and produced catabolites is rapidly increasing.
In general, flavonoids unabsorbed in the small intestine reach the colon, where they are exposed to
the gut microbiota.

Conclusion:

In this perspective article, colonic degradation of flavonoids is considered a reverse
process to their biosynthesis in plants, with a special focus on the subclass of flavones. According
to this approach: what is composed in plants, will be decomposed in the human colon. Several
inverse similarities are highlighted, including hydrolysis of flavonoid glycosides as the first step in
the gut degradation contrasted with the attachment of sugar moiety as the last reaction of flavonoid
biosynthesis in plants, colonic reduction contrasted with plant introduction of C2-C3 double bond
in the central heterocyclic ring, or microbial ring fission contrasted with plant ring closure of the
heterocyclic ring of flavones. Despite these inverse similarities, precursors of flavonoid pathway in
plants are different from the spectrum of gut microbial catabolites in humans. In the human colon,
a wide variety of phenolic acids are produced from the ingested flavonoids, due to the diverse enzymatic
capacity of intestinal microbiota. The bioactivities and potential health impacts of these
catabolites are still largely unknown.

This review revolves around the idea of inculcating and amalgamating all
the possible forte of healthcare that can be governed and handled by Blockchain
Technology (BCT). Relating back to all the archaic systems involved in the healthcare
sector, the entire process was quite slow and many a time leads to a significant amount
of delay in any process, be it report of the patient, tracking data from the smart watch,
ruling out appointment from a doctor, medicine prescription and many more. BCT in
fusion with the Internet of Things (IoT), leads to generating a completely revolutionary
and robust system that expands its range from very minute detail to a completely new
horizon. As predicted by 2022, more than 18 billion devices will be available across the
world; thus, managing this data that is related to healthcare, devising BCT for same can
yield some exponential results in advancement in health care sector. This entire
healthcare data is quite vulnerable to all the cyber-attacks and all the collected valuable
information may be at a huge risk; hence by deploying BCT, security can be greatly
increased. BCT is nothing but an immutable time stamp series of records, just like an
array working; when even one of the blocks is initialized with any value of
information, that piece of information will remain there forever. This review attempts
to group together all such various fields that can be brought under a single umbrella
covering the range of fields that can be governed by BCT in accordance with IoT for
the development of health care sector.
Coumarins as Carbonic Anhydrase Inhibitors
Authors: Supuran Claudiu T.
Published: December 2022

Carbonic anhydrases (CAs, EC 4.2.1.1) are metalloenzymes and relevant drug targets with many medicinal chemistry applications. Their classes of inhibitors are in clinical use as diuretics, or drugs for the management of glaucoma, epilepsy, obesity, tumors and infectious diseases. Among the inhibitors discovered so far, coumarins constitute an interesting class. They undergo CA-catalyzed hydrolysis and act as “prodrug inhibitors”, forming 2-hydroxy-cinnamic acids, which bind at the entrance of the enzyme active site, which has a relevant variability of amino acid residues among the different CA isoforms present in mammals, humans included. Coumarins act as isoform-selective CA inhibitors against pharmacologically relevant enzymes, such as the tumor-associated CA IX and XII. Coumarins present as metabolites in many species of bacteria, fungi, plants and ascidians showed relevant CA inhibitory properties and were used as leads for obtaining synthetic derivatives with enhanced enzyme inhibitory action belonging to a variety of classes, such as polysubstituted coumarins on both rings, thiocoumarins, thioxocoumarins, sulfocoumarins, etc.

Performance measurement is the process of making an evidence-based improvement. It reveals the performance gains or gaps, depending on the entity to be measured, being an organization, people, equipment, processes, or systems. After development, big data analytics (BDA) systems massively fail in organizational settings. The reasons, however, are not fully understood. This paper investigates how organizations can quantify the performance of their BDA systems. To answer this question, we investigated performance measures and performance-contributing factors in the existing literature and surveyed users’ perceptions of our findings. The results show that metrics of efficiency and effectiveness can be used to measure the performance of the BDA System. The results also demonstrate that technology, competency, and working conditions are the key factors that contribute to the performance of the BDA System.
Fabrication and Catalytic Property of an Ordered Terpyridine Pd(II)/Ni(II) Catalytic Monolayer for Suzuki Coupling Reactions
Authors: Wang Wei , Bi Sa , Li Huanhuan , Li Tiesheng
Published: December 2022

Fabrication, arrangement, and controllable composition of ordered organometallic films are critical for designing a highly active catalyst and investigating the catalytic mechanism. In this paper, an organometallic terpyridine Pd(II)/Ni(II) monolayer linked on the silicon substrate surface (denoted as Si-Tpy-Pd1/Ni1) was prepared and characterized using water contact angle, ultraviolet spectra, X-ray diffraction, scanning electron microscopy, and X-ray photoelectron microscopy. Si-Tpy-Pd1/Ni1 exhibited high catalytic activity, substrate applicability, and reusability after 5 runs. During recycling, the deactivation was induced by the aggregation of active Pd/Ni nanoparticles. The catalytic mechanism was heterogeneous and occurred on the Si-Tpy-Pd1/Ni1 monolayer surface; the mechanism was confirmed using hot filtrate, poison test, and a three-phase experiment. The real active center was Pdδ–/Niδ+ and was formed in situ on the organometallic monolayer surface, which acted as a precursor with a synergistic effect between Pd and Ni. The electron density of Pd became more negative because of electron transfer from Ni to Pd, which facilitated the oxidative addition reaction.
Using Twitter Data to Estimate the Prevalence of Symptoms of Mental Disorders in the United States During the COVID-19 Pandemic: Ecological Cohort Study
Authors: Cai Ruilie , Zhang Jiajia , Li Zhenlong , Zeng Chengbo , Qiao Shan , Li Xiaoming
Published: December 2022

Background

Existing research and national surveillance data suggest an increase of the prevalence of mental disorders during the COVID-19 pandemic. Social media platforms, such as Twitter, could be a source of data for estimation owing to its real-time nature, high availability, and large geographical coverage. However, there is a dearth of studies validating the accuracy of the prevalence of mental disorders on Twitter compared to that reported by the Centers for Disease Control and Prevention (CDC).

Objective

This study aims to verify the feasibility of Twitter-based prevalence of mental disorders symptoms being an instrument for prevalence estimation, where feasibility is gauged via correlations between Twitter-based prevalence of mental disorder symptoms (ie, anxiety and depressive symptoms) and that based on national surveillance data. In addition, this study aims to identify how the correlations changed over time (ie, the temporal trend).

Methods

State-level prevalence of anxiety and depressive symptoms was retrieved from the national Household Pulse Survey (HPS) of the CDC from April 2020 to July 2021. Tweets were retrieved from the Twitter streaming application programming interface during the same period and were used to estimate the prevalence of symptoms of mental disorders for each state using keyword analysis. Stratified linear mixed models were used to evaluate the correlations between the Twitter-based prevalence of symptoms of mental disorders and those reported by the CDC. The magnitude and significance of model parameters were considered to evaluate the correlations. Temporal trends of correlations were tested after adding the time variable to the model. Geospatial differences were compared on the basis of random effects.

Results

Pearson correlation coefficients between the overall prevalence reported by the CDC and that on Twitter for anxiety and depressive symptoms were 0.587 (P<.001) and 0.368 (P<.001), respectively. Stratified by 4 phases (ie, April 2020, August 2020, October 2020, and April 2021) defined by the HPS, linear mixed models showed that Twitter-based prevalence for anxiety symptoms had a positive and significant correlation with CDC-reported prevalence in phases 2 and 3, while a significant correlation for depressive symptoms was identified in phases 1 and 3.

Conclusions

Positive correlations were identified between Twitter-based and CDC-reported prevalence, and temporal trends of these correlations were found. Geospatial differences in the prevalence of symptoms of mental disorders were found between the northern and southern United States. Findings from this study could inform future investigation on leveraging social media platforms to estimate symptoms of mental disorders and the provision of immediate prevention measures to improve health outcomes.

Background

In a rapidly digitalizing world, the inability of older adults to leverage digital technology has been associated with weaker social connections and poorer health outcomes. Despite the widespread digital adoption in Singapore, older adults, especially those of lower socioeconomic status (SES), still face difficulties in adopting information and communications technology and are typically digitally excluded.

Objective

We aimed to examine the impact of the volunteer-led, one-on-one, and home-based digital literacy program on digital literacy and health-related outcomes such as self-reported loneliness, social connectedness, quality of life, and well-being for older adults of low SES.

Methods

A nonrandomized controlled study was carried out in Singapore between July 2020 and November 2021 involving 138 digitally excluded community-dwelling older adults aged ≥55 years and of lower SES. Older adults awaiting participation in the program served as controls. Older adults under the intervention were equipped with a smartphone and cellular data, underwent fortnightly to monthly digital literacy training with volunteers to learn digital skills, and digitally connected to their existing social networks. Primary outcome was the improvement in self-reported digital literacy. Secondary outcomes included improvements in University of California, Los Angeles 3-item loneliness scale, Lubben Social Network Scale-6, EQ-5D-3L and EQ visual analogue scale scores, and Personal Wellbeing Score.

Results

There were significant improvements in digital literacy scores in the intervention group as compared to controls (mean difference 2.28, 95% CI 1.37-3.20; P<.001). Through multiple linear regression analyses, this difference in digital literacy scores remained independently associated with group membership after adjusting for differences in baseline scores, age, gender, education, living arrangement, housing type, and baseline social connectivity and loneliness status. There was no statistically significant difference in University of California, Los Angeles 3-item loneliness scale, Lubben Social Network Scale-6, Personal Wellbeing Score, or EQ-5D Utility and visual analogue scale score.

Conclusions

This study adds to the growing research on digital inclusion by showing that a volunteer-led, one-on-one, and home-based digital literacy program contributed to increase digital literacy in older adults of low SES. Future studies should look into developing more older adult–friendly digital spaces and technology design to encourage continued digital adoption in older adults and, eventually, impact health-related outcomes.

Hypertension and osteoporosis are believed to be linked to to each other. Previous studies have suggested that the imbalance of calcium metabolism in hypertensive condition and the use of calcium channel blockers such as amlodipine may lower the density and quality of bone. Panoramic radiography has been widely used as a reliable tool in assessing bone quality. One indicator of bone quality in panoramic radiograph is the macrostructure evaluation of mandibular cortical bone by using various indexes such as mandibular cortical index (MCI) and antegonial index (AI). This research aimed to compare the bone quality of hypertensive patients with amlodipine and healthy individuals using MCI and AI. In this study we used sixty panoramic radiographs of hypertensive patients with amlodipine and healthy individuals, thirty for each group, with various aspects of demography. The MCI analysis was done by dividing the mandibular cortical shape into three different qualitative categories and the AI analysis was done quantitatively by measuring the width of mandibular cortical bone in antegonial region using ImageJ software. There were statistically significant differences in the results between the two groups in terms of both AI (p = 0.000) and MCI (p = 0.001) in which hypertensive group had lower score. Based on this research, there were differences of mandibular bone quality of hypertensive patients with amlodipine and healthy individuals, particularly in its macrostructure.

The elderly had various oral health issues, one of which is taste sensitivity. Taste sensitivity is highly affected by a person’s health, medication, eating habits, nutritional status, and oral hygiene. As an important organ for the sense of taste, the tongue can be covered in a white coating of debris, bacteria, and dead cells. To clean the tongue coating, one can do tongue brushing procedure, but this practice is not common among the elderly, especially in Indonesia. This cross-sectional study involved 114 older adults (n= 114) in the Special Region of Yogyakarta (Daerah Istimewa Yogyakarta- DIY), Indonesia, who were selected using stratified random sampling. The participants first signed the informed consent before undergoing an interview and going through oral clinical examination. This research particularly measured the tongue coating index and taste sensitivity level by way of statistically analyzing both variables to determine the correlation between tongue coating index and taste sensitivity level using three-dropmethod. Data from 114 subjects were presented descriptively using table and graphic. Most of the subjects 90.53% (103 subjects) had a coated tongue with various degree. The correlation statistic between tongue coating index and taste sensitivity level showed the statistically significant correlation (p-value = 0.019) and the coefficient correlation was -0.216, which means that there was a negative and weak correlation between both. Elderly with a higher tongue coating index tended to have less taste sensitivity. This could be due to debris blocking taste buds, thereby reducing taste sensitivity.

Sealer is one of root canal filler materials which has been developed and has an antibacterial agent to keep root canal sterile during and after an obturation process. This study aimed to find out the effect of sisal nanofiber addition to resin epoxy-based sealer on the antibacterial power against Enterococccus faecalis (E. faecalis) which is known as adaptive and potent bacteria which can be both aerobic and anaerobic. Sisal fibers were processed through many stages to make it nano sized (scouring, bleaching, neutralization, ultrasonification, and freeze-drying). Once nano-sized sisal fibers had been obtained, they were then mixed with sealer powder (AH26) in different concentrations: powder 0%, 0.25%, 0.5%, 0.75% and 1%. These concentrations were chosen based on preliminary research for reasonable contact angle measurement of sisal-sealer mixture. Antibacterial effect was examined using the diffusion method, each concentration was tested in 5 petri dishes which were planted with 1.5 X 108 CFU/ml E.faecalis bacteria. Each dish consisted of 5 holes (6 mm in diameter), each hole represented each concentration of nano sisal and sealer which were mixed until homogenous for 3 minutes before added to each hole. The dishes were then incubated for 48 hours at 37 °C. Inhibitory zones were measured, and analyzed using one-way ANOVA. The one-way ANOVA result showed that p=0.502 (p>0.05), meaning that the sisal nanofiber addition to epoxy resin-based sealer had no effect on E.faecalis inhibition. Thus, there was no effect of sisal nanofiber addition to epoxy resin-based sealer on E. faecalis.

Acrylic resin is the most common fabricated material for denture bases. ZrO2 nanoparticles can be used as filler to strengthen the physical properties and inhibit the adhesion of acrylic resins. This study aimed to examine the growth of Candida albicans and porosity in reinforced acrylic resin with Zirconium Dioxide (ZrO2) nanoparticles at 2.5% and 5% a concentration targeted for denture bases application. A laboratory experiment study included twenty-seven disc-shaped samples which were divided into three groups: group I acrylic resin without ZrO2 nanoparticles (control), group II acrylic resin with 2.5% ZrO2 nanoparticles, and group III with 5% ZrO2 nanoparticle acrylic resin. Samples were collected by heat polymerization while porosity observations were done using primo zeizs starr (Nikon YS100) microscope at 100x magnification. Dilution test was implemented to assess Candida albican growth. One-way ANOVA and Post Hoc LSD test statistical analysis were performed to evaluate the data (p<0.05). The results indicated that the mean porosity values in the control group of 2.5% and 5% were 37.4 ± 3.5, 15.8 ± 3.3, 8.0 ± 2.0 respectively while the attachment of C. albicans was 0.832 ± 0.083, 0.536 ± 0.098, 0.218 ± 0.083. One-way ANOVA confirmed a significant effect (p<0.05). Similarly, Post Hoc LSD test reported significant difference (p<0.05). The results showed that acrylic resin reinforced with ZrO2 nanoparticles for heat-polymerized denture base effectively reduced porosity and C. albicans adhesion. Five percent of ZrO2 nanoparticle concentration presented greater porosity reduction compared to 2.5% ZrO2 and non-reinforced acrylic resin. Acrylic resin reinforced with ZrO2 nanoparticles in 2.5% and 5% concentration is fungistatic.

The minimally invasive surgical technique (MIST) is a method for periodontal regenerative treatment by minimizing trauma so it can preserve vascular supply of the interdental papillae. This study aims to determine the effectiveness of the MIST method with the addition of a combination of hydroxyapatite and β-tricalcium phosphate (HA + β-TCP) in treatment of infrabony pockets in terms of alveolar bone density and osteocalcin levels of gingival crevicular fluid. The study sample was taken from 20 teeth with infrabony pockets (n = 20), which were divided into two groups: 10 teeth treated with MIST and the other group with open flap debridement (OFD). Both groups received combination of HA + β-TCP. The osteocalcin levels of gingival crevicular fluid were checked on day-0 prior to the flap surgery, day-7 and day-14 after flap surgery using the Human Osteocalcin Elisa Kit. Radiological evaluation of alveolar bone density at day-0 and day-90 was done using cone beam computed tomography. Data of osteocalcin levels were analyzed using two-way ANOVA and continued with LSD Post Hoc test, while data of alveolar bone density reduction were analyzed using the Independent t-test parametric test. The results showed that there was no significant difference (p > 0.05) in the values of alveolar bone density between the MIST and OFD groups on day-0 and day-90, while the osteocalcin levels in both groups showed an increase from day-0 to day-7 and a decrease from day-7 to day-14. There was a significant difference (p < 0.05) on day-0 and 7 and day-7 and 14 between MIST and OFD groups. The MIST method with HA + β-TCP was effective and further increases alveolar bone density and osteocalcin levels of gingival crevicular fluid.

Smear layer removal in root canal treatment is required to aid the diffusion of intracanal medicament and help sealer penetrate into dentinal tubules. The need for irrigants is important to facilitate smear layer removal in the root canal. Various methods have been proposed in some articles, but their application in apical third still challenges many clinicians due to the complexity of the root canal. This study aimed to analyze the effect of temperature and passive ultrasonic irrigation (PUI) activation of EDTA 17% solution in smear layer removal. Twenty-four extracted mandibular premolars were decoronated to standard root length of 14 mm. The preparation of root canals was completed with crown-down technique using ProTaper FHU to file F3 (30/.09). The root canal irrigation was done with NaOCl 5.25% and EDTA 17% solution. The samples were divided into four groups, namely 25 ºC of EDTA 17% solution (group 1), 37 ºC of EDTA 17% solution (group 2), 25 ºC of EDTA 17% solution with PUI activation (group 3), and 37 ºC of EDTA17% solution with PUI activation (group 4). Smear layer removal was observed under scanning electron microscopy (SEM) and scored ordinally from 1-5. Non-parametric Friedman test showed significant results in all the groups (p<0.05). Post hoc Wilcoxon Signed Rank test showed significant results between group 2 and group 3 (p = 0.039), and between group 3 and group 4 (p = 0.038). The combination methods of temperature and PUI activation showed a significant result in smear layer removal.
