Published: February 2024

AbstractCaCl2molten salt, as a common electrolyte in the process of molten salt electrolysis, has a high decomposition potential and a strong ability to bind O2−. So the study of the structure and properties of CaCl2is significant for the molten salt electrolysis. In this paper, molecular dynamics simulations (MD) method was used to investigate the variation rule of the local structure and physicochemical properties of CaCl2molten salt with temperature. The results show that the temperature has less effect on the heterozygous ion pairs and more effect on the homozygous ion pair. With the increase of temperature, the interaction between ion pairs is weakened, the coordination number decreases, the local structure changes a little, and the structural configuration tends to be an irregular octahedral structure with vacancies. The calculated self-diffusion coefficients, viscosities, and ionic conductivities are consistent well with the reality, but there is a significant error in densities due to the strong polarization effect of Ca2+compared to the reality. The local structure directly determines the thermodynamic properties of the molten salts. This study promotes the basic theoretical research on alkaline earth metal-containing molten salts and is an important reference for the study of molten salt electrolysis process.

Published: February 2024

Objective
Pregnancy is a state of physiological inflammation facilitating implantation. Early isolated hypothyroxinaemia (IH) and increased inflammation (including obesity) have been associated with severe obstetric complications. The current study evaluated the association between IH, low ferritin and inflammation parameters (interleukin 6 (IL-6), C-reactive protein (CRP), human chorionic gonadotrophin (hCG) and obesity. Moreover, the course of these parameters throughout pregnancy was evaluated in relation to IH.

Methods
In the cross-sectional study (A) at 12 weeks, 2759 women participated and 2433 participated in the longitudinal study (B) with assessments at 12, 20 and 28 weeks gestation. At the first trimester, 122 (4.4%) IH women (free thyroxine (FT4) <5th percentile, normal TSH levels) were compared with 2114 (76.6%) reference women (FT4 between tenth and 90th percentiles, normal thyrotrophin (TSH) levels), in study B these figures were 99 (4.1%) and 1847 (75.9%), respectively.

Results
Cross-sectionally, compared to reference women, IH was independently associated with low ferritin (<5th percentile, OR: 2.6, 95% CI: 1.4–4.9), high CRP (>95th percentile: OR: 1.9, 95% CI: 1.04–3.7), low hCG (<median, OR: 2.1, 95% CI: 1.40–3.16), obesity (BMI > 30, OR: 1.7, 95% CI: 1.12.9) and higher age (OR: 1.1, 95% CI: 1.04–1.15). Longitudinally, compared to reference women, women with IH at 12 weeks gestation showed persistently and significantly lower ferritin and hCG levels, and persistently higher CRP and IL-6 levels throughout gestation.

Conclusion
Gestational IH could be viewed as a condition of increased inflammation, as reported in non-thyroidal illness syndrome. Less favourable inflammation parameters and low iron status during early gestation in IH women seem to persist throughout gestation.
“[…]Ante el augusto tribunal de la opinión pública” : opinión pública, impresos y honor en el Caribe neogranadino, 1831-1857
Authors: Flórez-Bolívar Roicer 
Published: February 2024

El artículo analiza la relación entre opinión pública, impresos y honor en el Caribe neogranadino entre 1831 y 1857. Se argumenta que, adicional a la prensa, textos impresos como folletos, hojas volantes, anónimos, panfletos y pasquines jugaron un importante papel en la construcción y desarrollo de la opinión pública ya que a través de estos se ejercía control sobre el funcionamiento del Estado, desempeño de funcionarios y ministros de la Iglesia, la vida privada de los ciudadanos y otros. La fuente principal del estudio fueron 99 impresos —folletos, hojas volantes, anónimos y pasquines—y un manuscrito que reposan en la hemeroteca de la Biblioteca Nacional de Colombia. Esta investigación busca enriquecer las interpretaciones planteadas por la historiografía colombiana sobre la construcción de la opinión pública durante el siglo XIX. Una de sus conclusiones es que el análisis de las fuentes referenciadas es una ventana que nos aproxima a la cultura política de los habitantes de la región del Caribe neogranadino al mostrarnos como asimilaron e interiorizaron conceptos e imaginarios de la sociedad colonial como el honor y otros del vocabulario republicano como ciudadanía, libertad de opinión y debate.
From greenwashing to screenwashing?
Authors: Koning Ina Maria , van den Eijnden Regina J.J.M. , Vossen Helen G.M. 
Published: February 2024

AbstractIn this viewpoint, we introduce the term ‘screenwashing’, which describes the phenomenon whereby social media platforms, such as TikTok and Instagram, pretend to be more socially responsible than they actually are. That is, social media platforms pretend to be thoughtful about children's health and the prevention of problematic social media use, but this often turns out to be nothing more than “a lick of paint”. We describe how features like the one-hour notification on TikTok and Instagram are considered screenwashing and why we believe so. Screenwashing, an unethical practice, has the potential to mislead parents and young users. Consequently, we advocate for increased government intervention to protect our youth from the potential hazards associated with problematic social media use.
Designing for health: A study of architecturally oriented models of public space
Authors: Tu Kangwei , Reith Andras 
Published: February 2024

AbstractIn the post-pandemic period, cities are committed to creating healthier and more healing urban environments. In high-density urban environments, urban complexes are increasingly assuming the function of enriching the external space and activating the vitality of cities, and their architecturally oriented public spaces have great potential for the promotion of residents' health. However, current research on public space and health has focused on green spaces and neighborhoods, and has not yet systematically sorted out the pathways that influence how building-oriented public space can contribute to health. In order to fill the gap, this study attempt to establish a model of health-promoting architecturally oriented public space, which can provide a reference for the similar projects.

Published: February 2024

Investment is the placement of a number of funds or other resources carried out in the present to get future profits. Investors who invest in companies must know the factors that can cause profits or losses when investing. One of the factors that investors can consider to carry out investments is understanding financial statement information to determine the effectiveness of the company in generating the value of Working Capital to Total Assets (WCTA) or the company's ability to use the company's current assets, knowing the Net Profit Margin (NPM) to assess the company's ability to generate profits, as well as knowing the level of profit on the capital invested in the investment or Stock Return. The results indicated that partial Working Capital to Total Assets (WCTA) had no significant effect on Stock Return with a coefficient of determination of 8.2%. Partially, Net Profit Margin had no significant effect on Stock Return with a coefficient of determination of 12.5%. Thus simultaneously, Working Capital to Total Assets (WCTA) and Net Profit Margin had no significant effect on Stock Return with a coefficient of determination of 25.3%.Keywords: Working Capital to Total Asset (WCTA), Net Profit Margin (NPM), Stock Rteurn

Aim. To study the long-term effect of enhanced external counterpulsation (EECP) therapy on exercise tolerance, quality of life (QoL), and indicators of the structural and functional state of the cardiovascular system in patients with stable ischemic heart disease (IHD) complicated by chronic heart failure (CHF).Material and methods. This open randomized EXCEL study included 120 patients with verified IHD complicated by NYHA II-III functional class CHF with reduced or mid-range left ventricular (LV) ejection fraction. Patients were randomized into group 1 (n=40), optimal drug therapy (ODT) and EECP (35 hours, 2 courses per year); group 2 (n=40), ODT and EECP (35 hours, 1 course per year); and group 3 (control; n=40), ODT and placebo counterpulsation (35 h, 1 course per year). All patients underwent a 6-minute walk test (6MWT), evaluation of clinical status, QoL with the MLHFQ and SF-36 questionnaires, structural and functional state of large blood vessels and microvasculature, measurement of brain natriuretic peptide precursor (NT-proBNP), and echocardiography at baseline and after 12 months.Results. In groups 1 and 2 after 12 months, the 6MWT distance increased statistically significantly (44.5 and 24.9%, respectively) and the following indexes improved: QoL (SF-36, MLHFQ), the condition of large blood vessels (phase shift, radial augmentation index, central aortic systolic pressure (CASP)) and microvasculature (occlusion index, percentage of perfused capillaries, percentage of capillary recovery), and the LV systolic function (from 40.6±7.5 to 47.5±10.2% and from 41.3± 6.8 to 43.9±10.3%, respectively). The proportion of patients with a >20% increase in the 6MWT at 12 months was 97.5, 72.5, and 7.7%, respectively. A statistically significant decrease in NT-proBNP was observed in all groups. In group 3, the incidence of hospitalizations for CHF and the risk of the composite endpoint were significantly higher.Conclusion. For the 12-month study period, the effects of EECP in patients with IHD complicated by CHF included improvements in exercise tolerance, QoL, vascular and cardiac functional parameters, and a decrease in the incidence of adverse outcomes.

Published: February 2024

Aim. To develop prognostic models for arterial hypertension (AH) and atherosclerosis based on studying the totality and significance of traditional and disease-mediated risk factors (RFs) in women with rheumatoid arthritis (RA).Material and methods. 223 female patients with RA aged 54.9±2.1 years were evaluated at the premises of the polyclinic of the Gulla Municipal Hospital #4 (Barnaul), the "Health Center", the City Rheumatology Department of the polyclinic, and the Hospital Department in 2016-2019. Statistical analysis was performed using Excel Microsoft Office 2007, Statistica 6.0 and 10.0, and SigmaPlot 12.5 software packages. Multivariate regression analysis was used for studying the attributes influencing the development of AH and atherosclerosis in RA and for constructing predictive models. ROC analysis was used to determine the quality of the developed models. Differences were considered statistically significant at p<0.05.Results. The following RFs predominating in the onset of disease were identified: traditional (hyperglycemia, obesity, increased diastolic BP (DBP), tachycardia, dyslipidemia); disease-mediated (ESR, fibrinogen, C-reactive protein (CRP), rheumatoid factor, cyclic citrullinated peptide antibodies, moderate and high DAS-28 activity), and psychosocial (stress, anxiety, depression, sleep disorders). The highest RF incidence and their combinations were determined with a RA duration of more than a year: traditional (obesity, hyperglycemia, increased systolic BP (SBP)), and decreased glomerular filtration rate; and disease-mediated (prednisolone treatment). A highly sensitive model for AH screening was developed that included a combination of RFs: disease-mediated (RA duration, CRP); traditional (improper diet, low physical activity, history of early cardiovascular diseases, increased SBP and DBP, preeclampsia and/or eclampsia, early menopause, older age, dyslipidemia); psychosocial (anxiety, depression), and a high salt-taste threshold. A highly sensitive model was developed for probable prediction of multifocal atherosclerosis in RA in women. The model includes a complex of risk factors: disease-mediated (RA activity by DAS-28, CRP, fibrinogen, ESR, dose-dependent prednisolone treatment); traditional (AH, SBP, waist circumference, heart rate, early menopause, preeclampsia and/or eclampsia, age 55 years and older, dyslipidemia); and psychosocial (sleep disorders, depression).Conclusion. Algorithms for early prevention of AH and atherosclerosis were developed with consideration of identified predictors and proposed prediction models for women with RA.

Authors: Aditama Wiwit , Fahira Miftahul 
Published: February 2024

Background: Workplace fatigue is a major concern that demands proper management, as it can result in various health issues. Gas station attendants who remain stationary for prolonged periods are especially susceptible to this problem. Therefore, this study aims to examine the relationship between standing time and work fatigue among Simpang Jam gas station operators in Banda Aceh City.
Research method: In order to explain the relevance between standing period and work fatigue, this study uses descriptive analytics. All 30 officers participated in the study as the population. At the Simpang Jam Gas Station in Banda Aceh City, this study was carried out in June. Chi-Square test was conducted.
Results: 40.0% of respondents reported being at risk and frequently worn out when standing for extended periods. Additionally, 91.7% of respondents experienced discomfort and exhaustion while working in standing positions.
Conclusion: Standing time and work fatigue have a relationship with a P value of 0.017, and standing work position and work fatigue have a relationship with a P value of 0.005.
Suggestion: When operators begin to experience signs of work fatigue, provide chairs for them and pay closer attention to rest periods.

Background: Lymphopenia is common in COVID-19. This has raised concerns that COVID-19 could affect the immune system akin to measles infection, which causes immune amnesia and a reduction in protective antibodies.
Methods: We recruited COVID-19 patients (n = 59) in Helsinki, Finland, and collected plasma samples on 2 to 3 occasions during and after infection. We measured IgG antibodies to diphtheria toxin, tetanus toxoid, and pertussis toxin, along with total IgG, SARS-CoV-2 spike protein IgG, and neutralizing antibodies. We also surveyed the participants for up to 17 months for long-term impaired olfaction as a proxy for prolonged post-acute COVID-19 symptoms.
Results: No significant differences were found in the unrelated vaccine responses while the serological response against COVID-19 was appropriate. During the acute phase of the disease, the SARS-CoV-2 IgG levels were lower in outpatients when compared to inpatients. SARS-CoV-2 serology kinetics matched expectations. In the acute phase, anti-tetanus and anti-diphtheria IgG levels were lower in patients with prolonged impaired olfaction during follow up than in those without.
Conclusions: We could not detect significant decline in overall humoral immunity during or after COVID-19 infection. In severe COVID-19, there appears to be a temporary decline in total IgG levels.
Robotics and Navigation Do Not Affect the Risk of Periprosthetic Joint Infection Following Primary Total Hip Arthroplasty
Authors: LaValva Scott M. , Chiu Yu-Fen , Fowler Mia J. , Lyman Stephen , Carli Alberto V. 
Published: February 2024

Background:
The use of computer navigation or robotic assistance during primary total hip arthroplasty (THA) has yielded numerous benefits due to more accurate component positioning. The utilization of these tools is generally associated with longer operative times and also necessitates additional surgical equipment and personnel in the operating room. Thus, the aim of this study was to evaluate the impact of technology assistance on periprosthetic joint infection (PJI) after primary THA.

Methods:
We retrospectively reviewed the records for 12,726 patients who had undergone primary THA at a single high-volume institution between 2018 and 2021. Patients were stratified by surgical technique (conventional THA, computer-navigated THA [CN-THA], or robotic-assisted THA [RA-THA]) and were matched 1:1 with use of propensity score matching. Univariate and logistic regression analyses were performed to compare the rates of PJI within 90 days postoperatively between the cohorts.

Results:
After propensity score matching, there were 4,006 patients in the THA versus RA-THA analysis (2,003 in each group) and 5,288 patients in the THA versus CN-THA analysis (2,644 in each group). CN-THA (p < 0.001) and RA-THA (p < 0.001) were associated with longer operative times compared with conventional THA by 3 and 11 minutes, respectively. The rates of PJI after conventional THA (0.2% to 0.4%) were similar to those after CN-THA (0.4%) and RA-THA (0.4%). On the basis of logistic regression, the development of PJI was not associated with the use of computer navigation (odds ratio [OR], 1.8 [95% confidence interval (CI), 0.7 to 5.3]; p = 0.232) or robotic assistance (OR, 0.9 [95% CI, 0.3 to 2.3]; p = 0.808).

Conclusions:
Despite longer operative times associated with the use of computer navigation and robotic assistance, the use of these tools was not associated with an increased risk of PJI within 90 days after surgery.

Published: February 2024

One sector that continues to experience development is the telecommunications sector. Telecommunications can make it easier to obtain information and carry out various activities. The communication sector has a vital role in the continuity and smoothness of communication. The objective of this research is to establish the correlation between the perceived price, perceived trust, perceived value, satisfaction, and repeat purchase intention of an Internet telecommunication service among individuals belonging to Generation Y and Z. The researchers introduce perceived trust as a new and innovative aspect of their study. Mean-End Chain Theory is used in research as the leading theory. The method in this study uses a quantitative approach using purposive sampling techniques, which resulted in 155 samples. The analytical approach utilised in the present investigation was. Structural Equation Modelling (SEM), using the AMOS Graphics 24 programmed. The study's findings suggest that the perceived price has a notable adverse impact on satisfaction. The perceived price and perceived trust favourably and dramatically effect the perceived value. This research is helpful in that mobile provider managers should improve perceived trust and perceived price of services by contributing to an event and being active in online marketing.
