Occlusal Contact Surface Changes and Occlusal Force Distribution Between Vacuum-Formed Retainers and Other Retainers: A Systematic Review.

The present systematic review was done to assess the available literatures on changes in the number of occlusal contacts (NOC), occlusal contact surface areas, and occlusal force distribution (OFD) with vacuum-formed retainers (VFRs) or clear overlay retainers during retention and to compare them with other retainers. Six electronic databases (Web of Science, Scopus, PubMed, Cochrane Library, Lilacs, and Google Scholar) were searched. Randomized controlled trials (RCTs) and controlled clinical trials(CCTs) reporting on occlusal contact changes with VFRs were included. A total of nine articles were included in this review: three RCTs, five prospective controlled trials (PCTs), and one CCT. The Cochranerisk of biastool and ROBINS-I tool were used for risk of bias assessment. The three RCTsshowed moderate risk of bias, and out of five CCTs, four showed low risk of bias, and one showed moderate risk of bias. One CCT showed a low risk of bias in the ROBINS-I tool. Two out of four studies reported improved occlusal surface area (OSA) with VFRs when assessed at the end of six months and 12 months; one out of four studies reported improved NOC; and one study reported a decrease in OFD anteriorly and an increase in OFD posteriorly after two months of retention. On comparison between the groups, the other retainer groups showed more NOCs compared to VFRs. The limited available evidence suggests an increase in OSA andno change in NOCs and OFD with VFRs during retention. Nosignificant differences between VFRs and other retainers for OSA and OFD were noted, and more NOCs were noted for other retainer groups.

The role of social network structure and function in moderate and severe social and emotional loneliness: The Dutch SaNAE study in older adults

BackgroundLoneliness is a serious public health problem. This became even more visible during the COVID-19 pandemic. Yet, the key social network aspects contributing to loneliness remain unknown. Here, we evaluated social network structure and function and associations with (moderate/severe) social and emotional loneliness in older adults. MethodsThis cross-sectional study includes online questionnaire data (SaNAE cohort, August–November 2020), in independently living Dutch adults aged 40 years and older. For the separate outcomes of social and emotional loneliness, associations with structural social network aspects (e.g., network diversity - having various types of relationships, and density - network members who know each other), and functional social network aspects (informational, emotional, and practical social support) were assessed and risk estimates were adjusted for age, educational level, level or urbanization, comorbidities, and network size. Multivariable logistic regression analyses were stratified by sex. ResultsOf 3396 participants (55 % men; mean age 65 years), 18 % were socially lonely which was associated with a less diverse and less dense network, living alone, feeling less connected to friends, not having a club membership, and fewer emotional supporters (men only) or informational supporters (women only). 28 % were emotionally lonely, which was associated with being socially lonely, and more exclusively online (versus in-person) contacts (men only), and fewer emotional supporters (women only). ConclusionNetwork structure and function beyond the mere number of contacts is key in loneliness. Public health strategies to prevent loneliness in older adults should be sex-tailored and promote network diversity and density, club membership, informational and emotional support, and in-person contact.

Structure-guided screening of protein-protein interaction for the identification of Myc-Max heterodimer complex modulators

De-regulation of oncogenic myelocytomatosis (c-Myc or Myc) transcription factor is one of the most common molecular anomalies encountered in human cancers, and it is typically linked to many aggressive malignancies including breast, lung, cervix, colon glioblastomas, and other haematological organs. The Myc belongs to the basic helix-loop-helix zipper protein family (bHLH-ZIP), and its dimerization with another principal interactor protein partner Myc-associated factor X (Max) is essentially required for cellular transformation, cell growth and proliferation, and transcriptional activation. Intermolecular interactions have been evaluated between hetero-dimer Myc-Max protein, which identified protein-protein interaction (PPI) specific modulators using highly précised molecular docking study followed by long-range interaction stability analyzed through molecular dynamic (MD) simulation. Moreover, ADME profile analyses have been estimated for screened hit compounds. MM-GBSA-based binding free energy (ΔG) estimations have been performed for all screened hit compounds obtained from multi-step molecular docking-based virtual screening technique. According to the employed various rigorous multi-chemometric techniques, four identified inhibitors/modulators appear to have a considerable number of intermolecular contacts with hotspot residues in the hetero-dimer interface region of the Myc-Max PPI complex. However, identified hit compounds might need further structural optimization or extensive biophysical analyses for better understanding of the molecular mechanism for exhibiting the Myc-Max PPI interface binding stability.

Updates on syringe coverage and service uptake among needle and syringe programs in the United States, 2019–2020

BackgroundAs injection drug use has increased in the US, so too has the prevalence of receptive syringe sharing. Since the 1980s, Needle and Syringe Programs (NSPs) have been an important source of clean injection equipment and disposal of used syringes. This study reports national syringe coverage and examines the impact of program attributes on organizational-level service uptake, defined as number of syringes distributed per participant contact per year. MethodsIn 2019 and 2020, we administered an annual cross-sectional survey to NSPs operating in the US (n = 260). A national estimate of coverage was calculated by dividing the total number of syringes distributed by the 2019 and 2020 population estimate of people who inject drugs (PWID). Frequency distributions and percentages were calculated for categorical variables (e.g., funding, census region, distribution policy/modality), and median and interquartile ranges (IQR) were calculated for continuous variables (e.g., participant contacts, syringes distributed). Bivariate and multivariable mixed effects logistic regression models were used to estimate the odds ratio associated with organizational characteristics on increasing service uptake at the NSP level. ResultsFrom 2019 to 2020, the total number of participant contacts by NSPs increased from 871,976 to 898,891, and the number of syringes distributed increased from 92,648,529 to 113,071,748. The national coverage estimate increased from 29.5 (95 % CI = 15.0, 58.2) to 35.8 (95 % CI = 18.2, 70.6) syringes per PWID. Fifty-eight percent of NSPs increased service uptake in 2020 as compared to the previous year. NSPs that received government funding and NSPs that changed to a less restrictive syringe distribution policy were more likely to increase service uptake (aOR 1.80, 95 % CI = 1.01, 3.22 and aOR 3.33, 95 % CI = 1.11, 9.94, respectively). Syringe distribution modalities also diversified, with more NSPs reaching participants via backpacking/outreach, fixed site pop-ups, mobile delivery, mail-based delivery, leaving supplies out, and secondary distribution. ConclusionBoth governmental investment in harm reduction programming and needs-based distribution of syringes increased service uptake and thus should be expanded and sustained to reduce harms associated with injection drug use.

Gastrodin alleviates NTG-induced migraine-like pain via inhibiting succinate/HIF-1α/TRPM2 signaling pathway in trigeminal ganglion

BackgroundIncreasing evidence highlights the involvement of metabolic disorder and calcium influx mediated by transient receptor potential channels in migraine; however, the relationship between these factors in the pathophysiology of migraine remains unknown. Gastrodin is the major component of the traditional Chinese medicine Tianma, which is extensively used in migraine therapy. PurposeOur work aimed to explore the analgesic action of gastrodin and its regulatory mechanisms from a metabolic perspective. Methods/resultsAfter being treated with gastrodin, the mice were given nitroglycerin (NTG) to induce migraine. Gastrodin treatment significantly raised the threshold of sensitivity in response to both mechanical and thermal stimulus evidenced by von Frey and hot plate tests, respectively, and decreased total contact numbers in orofacial operant behavioral assessment. We found that the expression of transient receptor potential melastatin 2 (TRPM2) channel was increased in the trigeminal ganglion (TG) of NTG-induced mice, resulting in a sustained Ca2+ influx to trigger migraine pain. The content of succinate, a metabolic biomarker, was elevated in blood samples of migraineurs, as well as in the serum and TG tissue from NTG-induced migraine mice. Calcium imaging assay indicated that succinate insult elevated TRPM2-mediated calcium flux signal in TG neurons. Mechanistically, accumulated succinate upregulated hypoxia inducible factor-1α (HIF-1α) expression and promoted its translocation into nucleus, where HIF-1α enhanced TRPM2 expression through transcriptional induction in TG neurons, evidenced by luciferase reporter measurement. Gastrodin treatment inhibited TRPM2 expression and TRPM2-dependent Ca2+ influx by attenuating succinate accumulation and downstream HIF-1α signaling, and thereby exhibited analgesic effect. ConclusionThis work revealed that succinate was a critical metabolic signaling molecule and the key mediator of migraine pain through triggering TRPM2-mediated calcium overload. Gastrodin alleviated NTG-induced migraine-like pain via inhibiting succinate/HIF-1α/TRPM2 signaling pathway in TG neurons. These findings uncovered the anti-migraine effect of gastrodin and its regulatory mechanisms from a metabolic perspective and provided a novel theoretical basis for the analgesic action of gastrodin.

The Influence of Visual Appeal and Perceived Enjoyment on Brand Loyalty Through Customer Trust for Shopee Users in Yogyakarta

Facing increasingly fierce competition, one of the main strategies is to increase customer loyalty. Customers are the lifeblood of a business, because from customers a business gets income. Customer loyalty is the tendency for customer attitudes and behavior to favor one brand over another. Loyal ones will show an attitude of wanting to maintain relationships with service providers, such as a willingness to provide contact numbers, receive information/promotions, or provide recommendations. The population in this study were all students using Shopee in Yogyakarta. The sampling technique was purposive sampling with a sample size of 130 people. Data collection was carried out using questionnaires and data analysis in this research used Smart PLS. The influence of visual appeal, perceived enjoyment and customer trust is stated to be positive and significant because the original sample value obtained is positive and the p value is <0.05. The test results using the PLS approach produced a coefficient value for the influence of visual appeal on brand loyalty through customer trust with a value of 1.809 (p value 0.070 > 0.05), so it can be concluded that visual appeal has no effect on brand loyalty through customer trust. The test results using the PLS approach produced a coefficient value for the influence of perceived enjoyment on brand loyalty through customer trust with a value of 3.742 (p value 0.000 < 0.05), so it can be concluded that perceived enjoyment has a positive and significant effect on brand loyalty through customer trust.

Marketing automation, social networks, workspace and investments for industry 5.0

Human-centricity, sustainability, and resiliency are attributes defining industry or society 5.0 which are approaching the value chain from needs of consumers to resources of suppliers. Tested impact of resources from those opposed ends of the value chain in two studies was incorporated to marketing strategy through their roles in scenarios. The objective of this article is to demonstrate how positivist studies stimulate followers to become part of scenarios and strategies developing market and institutions towards sustainability, resilience and human-centricity of industry 5.0. Our results demonstrate that short learning time social networks have reached a high number of contacts for branding opposed to marketing automation which generated sales from few contacts. Workspace redesign according to 5S decreased time of operations seven times. It allowed either to process seven times more resources or save time of own staff, or staff tendering projects as outsourced knowledge in comparison with purchased investments such as RFID and IoT. Roles were interacted in scenarios to elaborate marketing strategy for such dominating situations as market economy, sharing economy, and war.

Impact of specialist ataxia centres on health service resource utilisation and costs across Europe: cross-sectional survey

BackgroundLittle is known about the costs of treating ataxia and whether treatment at a specialist ataxia centre affects the cost of care. The aim of this study was to investigate whether patients who attended specialist ataxia centres in three European countries reported differences in their health care use and costs compared with patients who did not attend a specialist ataxia centre. We compared mean resource use and health service costs per patient affected by ataxia in the United Kingdom, Italy and Germany over a 12-month period. Data were obtained from a survey distributed to people with ataxia in the three countries. We compared mean resource use for each contact type and costs, stratifying patients by whether they were currently attending a specialist ataxia centre or had never attended one.ResultsResponses were received from 181 patients from the United Kingdom, 96 from Italy and 43 from Germany. Differences in the numbers of contacts for most types of health service use between the specialist ataxia centre and non-specialist ataxia centre groups were non-significant. In the United Kingdom the mean total cost per patient was €2209 for non-specialist ataxia centre patients and €1813 for specialist ataxia centre patients (P = 0.59). In Italy these figures were €2126 and €1971, respectively (P = 0.84). In Germany they were €2431 and €4087, respectively (P = 0.19). Inpatient stays made the largest contribution to total costs.ConclusionsWithin each country, resource use and costs were broadly similar for specialist ataxia centre and non-specialist ataxia centre groups. There were differences between countries in terms of health care contacts and costs.

Impact of Rejuvenator-Modified Mastic on Asphalt Mixture Stiffness: Meso-Scale Discrete Element Method Approach

Encapsulated rejuvenators embedded in asphalt mixtures are a promising technology to extend the service life of asphalt pavements. However, their effects on the asphalt mixture’s performance still need to be properly understood. A recently developed three-dimensional discrete element method framework enables the evaluation of non-homogeneous distributions of the rejuvenator, closely resembling real conditions. This includes different scenarios involving capsule content and release efficiency. The presented numerical results show that the rejuvenator-to-mastic ratio and the number of rejuvenator-modified contacts influence the stiffness properties of asphalt mixtures. In cases where a homogeneous rejuvenator distribution is assumed, the three-dimensional DEM model predicts a significant reduction in the asphalt mixture’s stiffness that compromises the pavement’s performance. Simulations show that the diffusion effect needs to be considered for predicting the post-healed behavior of asphalt mixtures. For cases considering more suitable modified mastic amounts (less than 1.20 wt%), the effect on the asphalt mixture’s stiffness modulus is less pronounced, and the phase angle is not significantly affected. Additionally, the presented simulations suggest that the capsule content can be increased up to 0.75 wt%, and capsules with a release rate higher than 48% can be used without compromising the rheological performance of asphalt mixtures, possibly improving their self-healing properties. These numerical insights should be considered in future designs to achieve optimal post-healed behavior.

Healthcare use in patients with cardiovascular disease and depressive symptoms – The impact of a nurse-led internet-delivered cognitive behavioural therapy program. A secondary analysis of a RCT

BackgroundDepressive symptoms in patients with cardiovascular disease (CVD) can lead to increased healthcare use. In a randomized controlled trial (ClinicalTrials.gov, NCT02778074), we reported that a 9-week internet-delivered cognitive behavioural therapy (iCBT) program (n = 72) compared to an online discussion forum (ODF) (n = 72) had moderate to large effect on depression in CVD outpatients. In this secondary analysis, we aimed to describe and compare the effect of iCBT compared to ODF regarding healthcare use and to identify factors impacting healthcare use in these groups. MethodsData on healthcare use were retrieved from care data registries in five hospitals in Southeastern Sweden. ResultsThe year prior to intervention, the iCBT group had a mean of 31 outpatient clinic/primary care contacts per patient compared with 21 contacts the year after. The corresponding numbers for the ODF group were 37 and 25. The decrease was 32 % in both groups and did not differ significantly (p = 0.261 and p = 0.354) between the groups. Regarding hospital admissions, the iCBT group had 0.8 admissions per patient the year before and 0.6 the year after the intervention, a decrease by 25 %, whereas the ODF group had 1.1 and 0.6 admissions respectively, a decrease by 45 %. The difference was not statistically significant (p = 0.270 and p = 0.883) between the groups. Improvement in depressive symptoms post intervention were significantly (Beta = 0.459, p = 0.047) associated with a decrease in number of outpatient contacts in the iCBT group. In the ODF group, better mental health-related quality of life post intervention was significantly (Beta = −0.429, p = 0.045) associated with a decrease in number of hospital admissions. ConclusionReduced depressive symptom scores following intervention were associated with lower outpatient service use, but iCBT was not superior compared to ODF. This implicates that reducing depression in CVD patients, regardless of the type of internet-delivered intervention used, is important since it may reduce healthcare use in these patients.

Adsorption Efficiency of Carbon Materials for the Removal of Organic Pollutants: DDT from Aqueous Solution.

Carbon nanotubes (CNTs) are widely used to adsorb organic pollutants from wastewater due to their porous structure, large specific surface area, and unique physical and chemical properties. Examining the interactions between pollutant molecules and carbon nanotubes is an important topic in the applications of nanotubes for the removal of pollutants. In this study, molecular dynamics (MD) and metadynamics simulations were used to investigate the adsorption mechanism of Dichlorodiphenyltrichloroethane (DDT) pollutants on carbon nanotubes. Obtained results revealed that functionalized CNTs (f-CNTs) with active groups exhibited significantly enhanced performance compared to pristine CNTs. The adsorption isotherms were analyzed at different DDT concentrations, and it was found that increasing the concentration of DDT molecules led to a decrease in system energy and increased stability. The presence of biosurfactants as functional groups on the CNTs enhanced the interaction between DDT molecules and the nanotubes. In CNT, the addition of DDT increases the van der Waals energy from -176.83 kJ/mol for 3 DDT molecules to -2237.88 kJ/mol for 50 DDT molecules. In the case of f-CNT, the van der Waals energy in the system with 50 DDT molecules is about 2061.05 kJ/mol more negative than the system with 3 DDT molecules. The number of contacts between the adsorbent and DDT molecules increased over time, indicating increased adsorption interaction. The radial distribution functions (RDF) of DDT molecules around CNTs and f-CNTs showed the highest probability of finding DDT molecules at a distance of about 0.5 nm from the adsorbent surface. The study provided valuable insights into the adsorption process and can guide future experimental studies.

Particle morphology control for spherical powder fabrication using the ball milling process with DEM simulation

Characteristics of spherical particles on copper powder and changing sizes were studied in a ball mill under various experimental conditions, such as different ball diameters, high rotation speeds, and milling times, using a discrete element method (DEM) simulation. This experiment has investigated the characteristics of spherical particle morphology evolution involved in the mechanical alloying of copper powder. The morphological evolution of the copper particle was analyzed using scanning electron microscopy (SEM). A spherical copper particle was shown with a roundness value using imageJ software. The DEM was used to simulate the ball motion in a planetary ball mill, and the impact energy and shear energy generated during the collision were analyzed to estimate the contact number between the ball and the ball wall. Therefore, as the size of the ball decreased, the number of ball-to-ball and ball-to-wall contacts increased accordingly, and the spherical shape of the copper powder changed.

Regulation of Contact Interactions to Increase the Water Resistance of Air Binders

AbstractComposites based on mineral binders are highly concentrated polydisperse systems. These systems consist of a dispersed phase in the form of particles of filler and binder, hydration products, as well as a dispersion medium in the form of a porous electrolyte (mixing water). The properties of such systems are determined by the action of forces that manifest themselves in interfacial interactions and act within each phase between atoms, ions, or molecules. To increase the strength and water resistance of materials, it is necessary to ensure the formation of contacts in which electrostatic attraction with the maximum interaction energy is realized. A significant role is played by the electric charges and potentials of the surface of the particles of the components of the structure. The introduction of chemical additives provides the synthesis of additional crystalline hydrates with certain surface properties, which contributes to an increase in the number of electroheterogeneous contacts in the system. The introduction of polydisperse mineral fillers, taking into account their surface charges, ensures the formation of a dense structure of a composite material with a large number of electroheterogeneous contacts. Based on the research results, composite materials based on mineral binders of various functional purposes with specified physical‐mechanical, hydrophysical, electrophysical properties have been developed. The use of these materials made it possible to increase the reliability and durability of building structures.

Effectiveness of Recruitment Sources in a Multicenter Clinical Trial for Dementia Prevention ‐ rrAD study

AbstractBackgroundExercise and Intensive Vascular Risk Reduction in Preventing Dementia (rrAD Study) was a NIH‐funded multisite, clinical trial. The rrAD Study assesses the effects of aerobic exercise training and intensive pharmacological reduction of vascular risk factors on cognitive performance in older adults at high risk for Alzheimer’s disease (AD). The enrollment goal was 640 participants across the span of two years. We report herein our recruitment and enrollment results of the rrAD Study.MethodThe major inclusion criteria were older adults, age 60‐85, who had family history (FH) of dementia or subjective memory complaints, hypertension, and a sedentary lifestyle. Individuals with dementia and other neurodegenerative diseases, or unstable medical conditions were excluded (NCT02913664). 3,291 potential participants were recruited and 2,747 were phone screened to participate in the rrAD Study. 513 cognitively normal older adults, aged 60 to 85 years with hypertension and increased risk for AD were randomized.ResultThe rrAD Study had a 15.5% recruitment yield of total phone screened individuals to randomization. E‐mail brought in the largest number of phone screen contacts and was the overall most cited recruitment source (20.9%, n = 574, Figure 1), followed by interviews/editorials (18.7%, n = 515), other/unknown source (17.9%, n = 492), and broadcast advertising (11.8%, n = 325). E‐mail and interview/editorials led to greatest number of consented and randomized participants. However, the recruitment sources that were more likely to lead to consent/participation were, professional referral (i.e. physician, 57.1% yield), social media (49.2% yield), and mail/phone from site (45.2% yield).ConclusionFrom this outreach, the utilization of multiple recruitment sources prove to be a dominant factor to meet recruitment and enrollment goals. E‐mail and interview/editorials demonstrate to be the most effective recruitment sources that led to the greatest number of phone screens, consents, and randomizations. In future studies, we might limit the broadcast advertisement effort since it did not lead to a high volume of consents and randomization; this could be due to the limited amount of study information stated on a 60‐second radio advertisement. Whereas, e‐mail and interview/editorials may produce more qualified participants since these sources can provide a wide scope and detailed information about the study.

Effect of non-deformable and deformable bubbles on static yield stress of cement mortar

While extensive research has delved into the impact of single size distribution and volume fraction of bubbles on the static yield stress of cement mortar, this investigation pertains to previously underexplored variables. These encompass the ramifications of multi-size bubble distributions, variations in bubble geometries, disparities in air-liquid interfacial characteristics, and surfactant concentrations. In order to scrutinize these factors, bubbles exhibiting distinct volume fractions and size distributions were deliberately induced through the admixture of varying concentrations of nonionic surfactants, while maintaining a water-to-cement ratio (w/c) of 0.42 under controlled conditions at a temperature of 20 °C. Experimental testing involved the analysis of bubble deformation during the yield process of cement mortar, including a surface tension tester, micro-CT, and numerical simulations. Furthermore, the study investigated the influence of nonionic surfactants on the interaction forces between cement particles, employing comprehensive analysis methods such as a total organic carbon analyzer, Zeta potential measurements, and contact angle tests. The consolidated outcomes from experimental trials and numerical simulations substantiate that augmenting the concentration of nonionic surfactants does not amplify the interparticle interaction forces within cement particles. Rather, it solely leads to an escalation in the volume fraction of bubbles. During the cement mortar yielding process, bubbles exhibit two distinct states: deformable and non-deformable, characterized by the Bingham capillary number. Notably, the research reveals that the effect of increasing the volume fraction of non-deformable bubbles on the static yield stress is more significant than the impact of these bubbles on reducing maximum packing density. This effect is attributed to the increased number of contacts between particles. Additionally, the larger and flatter surface area of deformable bubbles promotes the orderly arrangement of cement particles, thereby reducing local shear dissipation. Consequently, an increase in the volume fraction of deformable bubbles and the Bingham capillary number contributes to a reduction in the static yield stress. In consideration of these discoveries, this study introduces a qualitative approach for characterizing the static yield stress of aerated cement mortar, leveraging the volume fractions of deformable and non-deformable bubbles, in conjunction with the maximum packing density and Bingham capillary number.

Roles were interacted in scenarios to elaborate marketing strategy for such dominating situations as market economy, sharing economy, and war. Sharing economy was the only alternative which allowed to develop markets and resources at ends of the value chain due to its found fast development. Therefore, our results suggest that social networks, marketing automation, 5S method, and technologies such as RFID and IoT are developing a sharing economy of 5.0 industry kind so fast that wars and market competition must fail.
