Introduction Cancer patients often face challenges in managing their disease, particularly with regard to contraindications related to medications, foods, and physical activity, which can negatively affect treatment outcomes. This study aimed to evaluate cancer patients’ awareness of these contraindications and to explore the influence of sociodemographic factors, support systems, comorbidities, and medication use on their knowledge. Methods A cross-sectional prospective study was conducted with 125 cancer patients in Saudi Arabia between December 2022 and February 2023. Participants were selected using purposive sampling, and data were collected through a validated questionnaire. Multinomial regression analysis was employed to identify the predictors of awareness of contraindicated medications, foods, and other environmental factors. Results Nationality, co-morbidities, and cancer duration were significant predictors of awareness regarding contraindicated drugs. Saudi patients were more likely to be aware of contraindicated medications ( P = 0.010), and those without chronic diseases were 15 times more likely to know about drug contraindications (OR = 15.076, 95% CI: 3.442-66.042). Cancer diagnosis ( P = 0.033) and cancer duration ( P = 0.022) were also significant for food contraindications. Over 58% were unaware of the need to regulate body temperature during treatment. Location influenced exercise awareness ( P = 0.064) and complementary and alternative medicine (CAM) awareness, with rural participants showing higher CAM knowledge ( P = 0.001). Conclusion This study emphasizes the need to improve cancer patients’ awareness of contraindications, particularly regarding medications and foods. Key factors influencing awareness include nationality, co-morbidities, and cancer duration. While family support is beneficial, it doesn’t directly enhance knowledge, highlighting the importance of targeted educational interventions to improve patient outcomes and safety.

Published: January 2025

Tooth whitening is nowadays one of the most requested aesthetic procedures by patients. Hydrogen peroxide contains unstable peroxides that produce oxygen free radicals, capable of breaking down the pigmented organic carbon components contained in the enamel matrix, converting them into shorter chain molecules and less pigmented, defined as oxidation, which continues for some time, and can decompose the organic materials into carbon dioxide and water, which would represent the loss of the enamel matrix1. One of the effects is the alteration of surface roughness and deeper cracks, as well as an increase in surface porosity, which could increase the adhesion of microorganisms. Objective: to determine if the adhesion of Candida albicans is greater in enamel subjected to bleaching with 35% hydrogen peroxide.Methods: The sample consisted of 20 healthy premolars extracted with orthodontic indication from patients between 13 and 35 years old with a post extraction time of less than 6 months.Two groups were randomly assigned, control group (no bleaching only sterile water) and experimental group (professional bleaching with 35% hydrogen peroxide). The teeth were sterilized and then incubated with Candida albicans for 36 hours. Then a sample of the vestibular side of the teeth was taken with sterile microbruhs to be centrifuged, and the seeding was performed in plates with sabouraud glucose agar from the supernatant of the centrifugation with a volume of 7 microliters, streaked with ansa. The CFU of both groups were quantified after 36 h of incubation in an oven at 37ºC. Results: The data were processed in Excel through the real statistics add-in system, the Shapiro Wilk test was applied to determine the normal distribution of the data, the F test for variances of two samples which resulted in equal variances; therefore, the parametric T-student test for independent samples for equal variances was selected. The result for one-tailed analysis was P value of 0.04 so we can think that this difference between control and experimental group exists, and in which case there was greater adherence of Candida in the control group compared to the experimental group. Conclusion: The literature is controversial, we can assume that the greater adherence of Candida albicans in the control group was due to the antimicrobial action of the bleaching agent on the experimental group.

ABSTRACT

The purpose of this research is to find out how much influence promotion has on customer satisfaction at PT Ecomerce Capital Indonesia in West Jakarta, to find out how big the influence of service quality is on customer satisfaction at PT Eccomerce Capital Indonesia in West Jakarta. and to find out how much influence promotion and service quality have on customer satisfaction at PT Ecomerce Capital Indonesia in West Jakarta". Both simultaneously. The research method in this research is a survey method. The population in this research is visitors to PT Eccomerce Capital Indonesia in West Jakarta" . totaling 1,978 customers. The sampling technique used was purpose method sampling, determining the sample size using the Slovin formula with a difficulty level of 10%, so a sample of 95 customer respondents was obtained. The test results for the promotion variable (X1) obtained a tcount value of 0.371 with a significance level of 0.711. This value is greater than 0.05 (0.711 > 0.05), so the equation obtained is tcount > ttable or 0.371 > 2.017, meaning Ho is accepted, Ha is rejected, in other words. Promotion variables have a significant effect on customer satisfaction. Meanwhile, the test results for the service quality variable (X2) obtained a calculated value of 3.645 with a significance level of 0.000. This value is smaller than 0.05 (0.000<0.05), so we get the equation tcount <ttable or 3.645>2.017. This means that Ho is accepted and Ha is rejected. in other words, the service quality variable has a significant effect on customer satisfaction. Thus, it can be interpreted that promotion and service quality simultaneously have a significant influence on customer satisfaction.

Published: August 2023

AbstractPulmonary arterial hypertension (PAH) is characterized by progressive pulmonary vascular remodeling with resultant abnormal increase in pulmonary artery pressure and right heart dysfunction. There is evidence that PAH includes cognitive impairment. However, the cognitive impairment syndrome has not been well described, and both the underlying mechanism and the relationship between cardiopulmonary and cognitive dysfunction in PAH are unknown. We performed cognitive evaluations and same day sub‐maximum cardiopulmonary exercise testing on adult subjects with PAH. A frontal–subcortical syndrome suggestive of vascular cognitive impairment was found in 26% of subjects and was associated with noninvasive markers of pulmonary vascular remodeling.
How long ago were the “good old days”? Comparing the prevalence of nostalgia in YouTube comments on music videos from recent versus distant decades
Authors: Areni Charles S. , Todres Mathew 
Published: August 2023

AbstractResearch on motives for using social media suggests competing hypotheses regarding how far back in time people vicariously travel to experience nostalgia online. Automated text analyses of user comments on 56 YouTube videos featuring Billboard Magazine's top 30 songs of the year from the 1950–2019 period identified clusters of co‐occurring words suggesting nostalgia. Boolean operators transformed the word clusters into sentence structures conveying nostalgia [e.g., (“miss” and ((“young” and “man”) or “days” or “times”)) → “I miss those days when I was a young man”]. Analysis of 37,217 comments revealed that the percentage expressing nostalgia was higher for videos from the 2000s–2010s compared to the 1950s–1980s. Social media has made instant online access to the recent past a normal part of daily life, making users more prone to expressing nostalgia toward relatively recent experiences.

AbstractTransition metal sulfides (TMSs) are perceived as competitive candidate anodes for sodium‐ion batteries (SIBs) on account of their high capacity and admirable reversibility. However, a majority of TMSs suffer from huge volume expansion and poor kinetics so they cannot achieve durable and fast Na+ storage. Herein, a cation vacancy‐ordered Cr2/3S is fabricated by extracting quantitative Cr atoms from nickel arsenide type CrS via sulfur “atomic pump,” that is, sulfur and particular sit Cr atoms are bonded to extend a new structure. The ordered vacancies not only construct a loosely‐packed crystal structure but also induce delocalized electron states of Cr atoms, hence effectively accelerating Na+ diffusion and releasing volume strain to enable high‐rate and longevous SIBs. The new Cr2/3S anode presents a high reversible capacity of 544 mAh g−1 after 100 cycles at 1 A g−1 and excellent high‐rate performance of ≈100% capacity retention after 7000 cycles at 20 A g−1. Subsequent in situ and ex situ characterizations reveal the Na+ storage mechanism of Cr2/3S. The proposed cation exaction strategy through an innovative sulfur “atomic pump” can be an efficient way to achieve loosely‐packed structure material for large‐capacity and fast‐kinetics anodes.

Published: August 2023

AbstractLi1.3Al0.3Ti1.7(PO4)3 (LATP) solid‐state electrolyte has garnered considerable interest owing to its competitive room‐temperature Li‐ion conductivity, air stability, and economic nature. Nevertheless, the successful implementation of LATP in next‐generation Li‐metal solid‐state batteries (SSBs) is impeded by its high incompatibility with Li metal. Herein, combining the Kevlar aramid nanofiber (KANF) membrane with a solidified electrolyte (SE) formed via in situ polymerization, the SE@KANF protective layer for LATP can be constructed. Such a protective layer not only effectively prevents Li metal from reducing LATP but also provides intimate interface contact and limits unnecessary electron transport. Consequently, Li symmetric battery incorporating SE@KANF layer enables an ultrahigh critical current density of 1.4 mA cm−2 and stably cycles for over 2000 h at 0.2 mA cm−2. Moreover, the full SSB coupling with LiFePO4 cathode delivers a capacity retention of 95% after 180 cycles at 0.1 C at 30 °C. The present study underscores the importance of the protective interface layer in stabilizing the LATP|Li interface.

AbstractOxidation states (OS) are the charges on atoms due to electrons gained or lost upon applying an ionic approximation to their bonds. As a fundamental property, OS has been widely used in charge‐neutrality verification, crystal structure determination, and reaction estimation. Currently, only heuristic rules exist for guessing the oxidation states of a given compound with many exceptions. Recent work has developed machine learning models based on heuristic structural features for predicting the oxidation states of metal ions. However, composition‐based oxidation state prediction still remains elusive so far, which has significant implications for the discovery of new materials for which the structures have not been determined. This work proposes a novel deep learning‐based BERT transformer language model BERTOS for predicting the oxidation states for all elements of inorganic compounds given only their chemical composition. This model achieves 96.82% accuracy for all‐element oxidation states prediction benchmarked on the cleaned ICSD dataset and achieves 97.61% accuracy for oxide materials. It is also demonstrated how it can be used to conduct large‐scale screening of hypothetical material compositions for materials discovery.

Published: August 2023

AbstractConducting polymers with high theoretical capacitance and deformability are among the optimal candidates for compressible supercapacitor electrode materials. However, achieving both mechanical and electrochemical stabilities in a single electrode remains a great challenge. To address this issue, the “Polymer Chainmail” is proposed with reversible deformation capability and enhances stability because of the steric hindrance and charge compensation effect of doped anions. As a proof of concept, four common anions are selected as dopants for Poly(3,4‐ethylenedioxythiophene) (PEDOT), and their effects on the adsorption and diffusion of H+ on PEDOT are verified using density functional theory calculations. Owing to the film formation effect, the
doped PEDOT/nitrogen‐doped carbon foam exhibits good mechanical properties. Furthermore, the composite demonstrates excellent rate performance and stability due to suitable anion doping. This finding provides new insights into the preparation of electrochemically stable conductive polymer‐based compressible electrode materials.

AbstractOne‐dimensional fiber architecture serves as an excellent catalyst support. The orderly arrangement of active materials on such a fiber substrate can enhance catalytic performance by exposing more active sites and facilitating mass diffusion; however, this remains a challenge. We developed an interfacial assembly strategy for the orderly distribution of metal nanocrystals on different fiber substrates to optimize their electrocatalytic performance. Using electrochemical nitrate reduction reaction (NO3−RR) as a representative reaction, the iron‐based nanofibers (Fe/NFs) assembly structure achieved an excellent nitrate removal capacity of 2317 mg N/g Fe and N2 selectivity up to 97.2 %. This strategy could promote the rational design and synthesis of fiber‐based electrocatalysts.

Published: August 2023

AbstractTwo‐dimensional (2D) AIE‐inorganic nanocomposites exhibit high stability and high fluorescence activity. However, limited by the types and properties of 2D inorganic materials, it's challenging to realize complex structures and functions. We designed a quaternary ammonium‐type AIE ligand, TPECholine. We chose TPECholine and POM clusters as building blocks and synthesized a series of single‐layer nanosheets (SLNSs) by assembling LnW10 or P2W18 POM clusters with TPECholine. By regulating the types of POM clusters and ligands, the morphology and fluorescence intensity of the SLNSs can be finely tuned. Due to the restriction of the intramolecular motions of AIEgens by the SLNSs, nanosheets can exhibit promoted quantum yield (up to 76 %). In addition, thanks to the sub‐nanometric sizes and excess surface charges, SLNSs exhibit excellent solvent compatibility, including water, chloroform, ethanol, etc. And the nanosheets showed high fluorescence intensity in these solvents.
Effect of calcium pimelate on crystallization kinetics of polyphenylene sulfide
Authors: Liu Huiqin , Feng Jiachun 
Published: August 2023

AbstractThe use of nucleating agents (NAs) to accelerate semicrystalline polymers crystallization is a widely recognized technique during processing. However, the commercially available NA for poly(phenylene sulfide) (PPS) has been rather limited. In this work, it is found that calcium pimelate (CaPim), a commercial nucleating agent for isotactic polypropylene, could also accelerate the crystallization process of PPS. The influence of CaPim addition on the crystallization behaviors of PPS was investigated under non‐isothermal and isothermal condition. Upon the addition of 0.3 wt% CaPim, the crystallization peak temperature and the onset crystallization temperature increases by 5.3 and 8.4°C at 10°C/min cooling rate, and the half‐time of crystallization reduces 51% at crystallization temperature of 272°C. Polarized optical observation revealed a substantial enhancement in nucleation due to the presence of CaPim. Avrami equation analysis suggested that the nucleating agent significantly increased the crystallization rate constant without affecting the growth dimension. Moreover, Lauritzen–Hoffman theory analysis indicateed that the addition of CaPim lowers the nucleation energy barrier, contributing to its high‐nucleation efficiency. These findings demonstrate that calcium pimelate holds promise as an effective nucleating agent for PPS.

AbstractAlthough there have been some studies on the preparation and characteristics of nano‐Fe3O4‐filled polyurethane (PU) composites, research focusing on the quantitative influence of the degree of microphase separation (DPS) and the crosslinking density (CLD) on dynamic viscoelastic properties is rare. In this paper, PU composites are synthesized by incorporating nano‐Fe3O4 as fillers. The dynamic mechanical properties under alternating loads are investigated using dynamic mechanical analysis. The influences of the DPS and the CLD on the dynamic hysteresis loss are analyzed. The experimental results show that the DPS and CLD of PU nanocomposites increase and then decrease with the increase of nano‐Fe3O4 addition and reached a maximum at the addition amount of 1.0 wt%. The quantitative relationships between DPS, CLD and the dynamic hysteresis loss of PU nanocomposites at different filler ratios are obtained. With a 1.0 wt% nano‐Fe3O4 content, the strain energy density (SED) and hysteresis energy density (HED) are increased by 416% and 354%, respectively. The hysteretic loss H indexes of all composites are kept lower than that of pure PU. These characteristics make nano‐Fe3O4‐filled PU a promising material for reducing the rolling resistance and increasing the service life of fuel‐saving tire materials.

Published: August 2023

AbstractHuisgen‐click curing systems are widely used in solid propellant binders due to their low humidity sensitivity and mild reaction conditions. However, the rigid triazole rings from the Huisgen‐click reaction decrease the molecular moving ability and increase decomposition temperature, lowering the mechanical and combustion performance. Thus, we bonded the Huisgen‐click system and polyester binders with urethane, forming microphase separation and improving chemical stability. The results show that the elongation at break, tensile strength, and Young's modulus of the binders increase by 533.3%, 201.2%, and 1263.9%, respectively. Furthermore, the urethane reduces the thermal resistance index of the binders from 191.2 to 179.2°C, which means better combustion performance. Further mechanism study reveals that the urethane leads to microphase separation, which aggregates the hard segments and weakens their restriction effect on the molecular motion of polyether. Such a microphase separation brings comprehensive improvement in the mechanical properties of the solid propellants and probably can be used in other multi‐component systems of energetic materials.

Published: August 2023

AbstractYouth with autism face challenges accessing services as they transition to adulthood. Improving parents' ability to advocate for services on behalf of their youth may be an effective way to improve service access and ultimately transition outcomes in this group. In this study, we tested whether participating in an advocacy intervention improved parents' ability to advocate for services for their transition‐aged youth with autism. One hundred and eighty‐five parents of youth with autism ages 16–26, recruited across three states in the U.S., were randomized to one of two experimental conditions. The treatment condition received the ASSIST program, a 12‐week (24‐h) group‐based intervention. The control condition received the same written materials as the treatment condition. Primary outcomes for this report—parent advocacy ability—were collected at baseline (prior to randomization) and post‐test (immediately after the treatment group finished the 12‐week program) by survey. After taking ASSIST, the treatment condition had greater gains than controls in knowledge of adult services (B = −1.62, CI = −2.33 to −0.90) and perceived advocacy skills (B = −0.19, CI = −0.33 to −0.04). Participants who had less knowledge, lower perceived advocacy skills, and less active coping styles at baseline had the greatest treatment gains. Findings suggest that ASSIST is effective in improving parent advocacy ability and may be most beneficial for parents who experience greater challenges advocating for their son/daughter with autism. Future research will examine whether gains in parent advocacy ability leads to improvements in service access and post‐school outcomes for transition‐age youth with autism.
