Published: February 2025

IntroductionAligned with the dual-factor model, this study aims to investigate why discharged patients seek online health information, considering the complexity of patients’ dilemmas. Additionally, we account for specific cultural context factor in China and seek to examine the role of living with children in mitigating the dilemmas faced by discharged patients in their pursuit of additional online information.MethodsWe empirically tested the research model using data collected from 292 discharged patients. The data was examined through structural equation modeling, employing Smart PLS.ResultsThe findings suggest that perceived stress facilitates discharged patients’ engagement in seeking online health information, whereas resistance to change and learned helplessness impede such behaviors. Furthermore, our analysis reveals that cohabiting with children moderates the effects of resistance to change on online health information-seeking behavior.DiscussionIn conclusion, this paper extends the literature by examining the role of discharged patients’ characteristics on online health information-seeking behaviors. Following the practices in China, this study involves living arrangements (with children) as an essential factor in the research model. This paper offer suggestions to online providers to make health-related information more suitable for discharged patients.

Published: February 2025

The marine dinoflagellate genera Coolia Meunier and Ostreopsis Schmidt have been reported in the Western Indian Ocean and include potentially harmful species. However, no comprehensive observations have been reported in Mauritian waters. The primary aim of this study was to isolate, identify and characterize potentially toxic epiphytic Coolia and Ostreopsis species from the coastal waters of Mauritius. Morphological characteristics were examined using light/fluorescence microscopy and scanning electron microscopy. The morphologies of the Coolia and Ostreopsis strains were similar to those of Coolia canariensis and Ostreopsis ovata. The phylogenetic analyses (large subunit ribosomal [LSU] rDNA D1/D2) revealed that the Mauritian strains of Coolia canariensis and Ostreopsis ovata clustered within the clades of these species complexes with other isolates from different areas. This represents the first record of Coolia canariensis in Mauritius, ascribed to C. canariensis phylogroups I and V, with the latter representing a new lineage of this species complex. The findings broaden the current body of knowledge of Coolia canariensis lineages, while the additional information of Ostreopsis ovata further supports the presence of an Indo-Pacific lineage.

This study hypothesized that alternating fresh and saline irrigation with different dripper types would optimize water use while minimizing negative effects on soil bulk density (ρb) and maize growth. The field experiment was carried out to investigate the impact of the types of the dripper and the salinity of irrigation water rotation on the ρb, maize (Zea mays L.) growth, and yield using two kinds of drippers (turbo and spiral) and two levels of irrigation water with different salinity ratios (low, symbolized by L) and (high, symbolized by H). Irrigation water was added into three rotations (L, H), (H, L, H), and (L, H, L). Soil ρb increased by 22.63% under saline irrigation, while yield was 3.07% higher with turbo drippers compared to spiral drippers. The results displayed an increase in plant height, leaf area, and yield by using the (L, H, L) as compared to (L, H) and (H, L, H), respectively. These results suggest that alternating fresh and saline water could reduce freshwater usage by 50% while maintaining acceptable crop yields, making it a cost-effective solution for water-scarce regions.

Abstract
Previous research has found that aesthetic appeal can facilitate visual search performance. One avenue of enquiry is that appealing icons are processed better than unappealing icons. If appealing stimuli are better processed, then it may be expected that they will benefit from practice more than their unappealing counterparts. In the current study (N = 100) we examined the effect of stimulus appeal on visual search performance. Half of the participants searched for appealing icons first, followed by unappealing icons, and the order was reversed for the other half. First, visual search performance benefited from stimulus appeal, and specifically the interaction of stimulus appeal and complexity – visual stimulus appeal led to better search performance but only for stimuli that were visually complex, with no effect of appeal for visually simple stimuli. Second, task experience benefited appealing icons more than unappealing icons. These results extend current knowledge of the status of visual aesthetic appeal on performance. They provide new evidence that appealing stimuli benefit from practice and are easier to learn compared to their unappealing counterparts.
Non-alcoholic fatty liver disease and osteoporosis: a bi-directional association
Authors: Dudinskaya E. N. , Onuchina Yu. S. 
Published: February 2025

Osteoporosis is a serious public health concern worldwide, characterized by decreased bone mineral density (BMD) and impaired microarchitecture of bone tissue, leading to an increased incidence of low-trauma fractures. Osteoporosis typically affects older adults, but it can also occur at younger ages due to impaired absorption of calcium and vitamin D in various gastrointestinal (GI) diseases. NAFLD is a risk factor for decreased bone mineral density (BMD). New data on the pathophysiological changes in bone tissue in NAFLD are presented: release of inflammatory cytokines, decreased secretion of molecules directly affecting bone (strengthening bone) from the liver affected by NAFLD, impaired vitamin D metabolism, and impaired intestinal microbiota. NAFLD is a risk factor for decreased BMD.Further research is needed to confirm the physiological significance of NAFLD with regard to the risk of osteoporotic bone fractures. Mandatory osteoporosis screening and bone health monitoring in patients with NAFLD may be possible in future NAFLD management strategies and guidelines.

BACKGROUND. Validation of the SCORE2 scale in the Russian population showed high accuracy in assessing cardiovascular risk (CVR) in men, but not in women. The development of new methods for assessing CVR in women is therefore an urgent task. A number of mammographic parameters, such as breast calcification (BC) and breast density (BD) can be additional biomarkers of cardiovascular diseases in women.AIM. To assess the relationship between the results of a retrospective analysis of mammograms and CVR in women aged 65 years and older.MATERIALS AND METHODS. Retrospective analysis involved the mammograms of 570 patients who subsequently underwent medical examinations at the Research and Educational Center of the Moscow State University. BD and BC were assessed based on scales developed by the American College of Radiology. The CVR was assessed in accordance with the Guidelines of the Russian Society of Cardiology. Statistical analysis was performed using the open-source R 4.1 environment.RESULTS. A relationship was found between mammographic parameters and CVR in women aged 65 years and older. Low BD, the presence and prevalence of BC were associated with higher CVR. The vascular type of calcifications was typical for patients with high and very high CVR. The absence of statistically significant differences in the density and calcification between the right and left mammary glands will be considered when developing an integral marker to verify the obtained results.CONCLUSIONS. A method for secondary analysis of preventive mammography data can help assess the CVR and determine rational routing of patients within the framework of the second stage medical examination. Downward reclassification of cardiovascular risk factors will help avoid unnecessary prescription of statins, while upward reclassification will help prescribe optimal treatment and provide additional motivation for women to correct cardiovascular risk factors.

Purple leaves in Indonesia can be used as an anti-inflammatory medication and laxative to treat hemorrhoids, rheumatism, boils, and skin diseases. Purple leaves are also used as free-radical antidotes. This was due to the presence of secondary metabolite compounds in purple leaves. The right extraction method determines the amount of flavonoids that can be extracted and achieves a high flavonoid content. This study aimed to determine the total flavonoid content and antioxidant activity of purple leaves using different extraction methods, namely maceration and Soxhletation. This study employed an experimental method of testing total flavonoid levels using UV-Vis spectrophotometry and antioxidant activity using the DPPH method. The results showed that the maceration method yielded a total flavonoid level of 4,422 ± 0,047 ppm, which was higher than that obtained using the Soxhletation method (1,547 ± 0,027 ppm). In the antioxidant activity test, vitamin C was used as a comparator, with an IC50 of 2.263 ppm (very strong). The IC50 of purple leaf extract using the maceration method was 123,32 ppm (medium), while the soxhletation method yielded an IC50 of 104,42 ppm (medium). This shows that vitamin C has more potent antioxidant activity in counteracting free radicals than purple leaf extract, using maceration and Soxhletation methods. The results showed a significant difference in total flavonoid levels using different extraction methods, while there was no significant difference in the antioxidant activity of purple leaf extract using maceration and Soxhletation methods.

Abstract
This Letter reports 12 novel spectroscopic detections of warm circumstellar dust orbiting polluted white dwarfs using the JWST Mid-Infrared Instrument (MIRI). The disks span 2 orders of magnitude in fractional infrared brightness and more than double the number of white dwarf dust spectra available for mineralogical study. Among the highlights are (i) the two most subtle infrared excesses yet detected, (ii) the strongest silicate emission features known for any debris disk orbiting any main-sequence or white dwarf star, (iii) one disk with a thermal continuum but no silicate emission, and (iv) three sources with likely spectral signatures of silica glass. The near ubiquity of solid-state emission requires small dust grains that are optically thin and thus must be replenished on year-to-decade timescales by ongoing collisions. The disk exhibiting a featureless continuum can only be fit by dust temperatures in excess of 2000 K, implying highly refractory material comprised of large particles, or non-silicate mineral species. If confirmed, the glassy silica orbiting three stars could be indicative of high-temperature processes and subsequent rapid cooling, such as occur in high-velocity impacts or vulcanism. These detections have been enabled by the unprecedented sensitivity of MIRI low-resolution spectrometer spectroscopy and highlight the capability and potential for further observations in future cycles.

Published: February 2025

Aim: The aim of the present study was to evaluate the surface changes in two different systems of rotary instruments before and after use by means of scanning electron microscopy (SEM) and energy dispersive analysis (EDA).
Materials and methods: We selected thirty files and divided them equally into two groups of 15 files each based on their manufacturing technology. Each file was used to prepare 5 root canals of freshly extracted human teeth. All the files were subjected to SEM and EDS before and after being used and the results compared to evaluate the surface changes. The results were then compared between the two groups using the t-test.
Results: The SEM images showed a greater mean difference in the surface changes before and after use for the system that employed only the M-wire manufacturing technology (1.46±1.68) vs. (3.07± 2.01), compared with the system that combined the M-wire and Gold manufacturing technologies (2.06±1.62) vs. (3.33±2.19). The most common observation in both systems was debris accumulation. Other notable findings included microfractures and file separation. The EDS results suggest that the more modern system has a higher loss of chemical composition after use compared to the system using only M-wire technology.
Conclusion: The present study provides evidence confirming that the use of Ni-Ti rotary file systems leads to the progression and possible creation of new surface changes. They increase the likelihood of iatrogenic errors and treatment failure in both file systems. Long-term use of files with gold manufacturing technology is not recommended, but for single use they outperform those with M-wire technology.
