Association between Visceral Fat Content and Obesity-Related Indicators with Cognitive Impairment after Intracerebral Hemorrhage
Authors: Wang Yuchen , Zhu Xutong , Zhang Xin 
Published: December 2024

Background: Intracerebral hemorrhage (ICH) is a major cause of morbidity and mortality, often leading to long-term cognitive impairment that significantly diminishes the quality of life. This study investigated the relationship between visceral fat content, obesity-related indicators, and cognitive dysfunction following ICH.
Methods: A total of 388 subjects with ICH who were admitted to the Neurosurgery Department of the Hospital and met the inclusion and exclusion criteria were included in this study. Obesity-related indicators, including body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR), were measured. L3 level images were obtained by abdominal computerized tomography (CT). The visceral fat content was estimated using IMAGE J software, and adiponectin levels were assessed via enzyme-linked immunosorbent assay (ELISA). The Mini-Mental State Examination (MMSE) was used to evaluate the cognitive level of patients within 2 weeks of onset, and the shortened version of the Montreal Cognitive Assessment (miniMoCA) was used to evaluate the cognitive level of patients 6 months after ICH. Univariate and multivariate analyses were used to analyze the correlations of BMI, WC, WHtR, abdominal fat, and adiponectin with cognitive impairment after ICH.
Results: BMI, WC, and WHtR were lower in the cognitive impairment group (p < 0.01). Overweight patients exhibited higher MMSE scores than normal-weight patients (p < 0.05) and higher miniMoCA scores than obese patients (p = 0.014). Abdominal obesity, assessed by WC and WHtR, was associated with higher MMSE scores (p = 0.022 and 0.003, respectively). Multivariate analysis indicated that WHtR was associated with cognitive impairment risk post-ICH (odds ratio (OR) = 0.233, 95% confidence interval (CI) (0.071, 0.762); p = 0.016). Although no overall association was found between adiponectin levels and cognitive impairment, subgroup analysis revealed lower adiponectin levels in overweight patients with cognitive impairment (p = 0.040).
Conclusion: WHtR is independently and inversely associated with cognitive impairment after ICH. There is no significant correlation between adiponectin with cognitive impairment after ICH, while subgroup analysis indicates that adiponectin levels are lower in overweight patients with cognitive impairment.

Published: December 2024

Background: University life is a phase of developing personal and professional skills, but it brings challenges such as distancing from family and supporting networks, difficulties with academic tasks, loneliness, new relationships, competitiveness, and social, socioeconomic, and psychological vulnerability, among others. These conditions can lead to the development of illnesses such as anxiety, depression, sleeping disorders, suicide, self-harming, and excessive drug use, including psychotropic medications. Therefore, this study aimed to evaluate the use of psychotropic medications and its association with sociodemographic, academic, behavioral, and health variables in Brazilian university students.
Methods: A cross-sectional, quantitative research, with a sampling of 524 students from a Brazilian public Higher Education Institution (Federal University of Mato Grosso - UFMT). The collection took place from October 10th to December 30th, 2022. An online questionnaire was applied with sociodemographic and clinical questions—the General Anxiety Disorder Questionnaire-7 (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9). The data were descriptively and inferentially analyzed; in the descriptive analysis, the absolute (FA) and relative (FR) frequencies of each category investigated were presented; and for bi- and multivariate analyses, Poisson regression with robust estimation was used.
Results: The participants were at the median age of 22 years old, the majority were female (69.7%), heterosexual (68.1%), with medium/high subjective social status (82.4%) and without being involved in a romantic relationship (54%). The prevalence of psychotropic medication use was 26.1%, considering that 17.5% was not prescribed by a medical professional. The most used class of medications was antidepressants (91 participants), followed by natural medicines (38 participants). Among the segments associated with the use of psychotropic drugs were female individuals, romantic relationships, perception of academic performance by postgraduate students, and previous diagnoses of mental or mood disorders (depression and anxiety).
Conclusions: The results obtained highlight the importance of research on mental health among university students, especially regarding the use of psychotropic drugs, which must be monitored by a qualified professional. At the university, these data can be important for the development of policies aimed at health and life quality, in addition to contributing to the strengthening of national and international partnerships, and promoting the scientific production in the area.

Published: December 2024

<p>This study aims to explore the influence of employee attractiveness on service recovery paradox by using Eye Tracker and Facial Recognition Software. Based on two service recovery scenarios an experiment was carried out with the participation of 20 subjects in Turkey. In the experiment participants’ pre-and post-satisfaction levels before the service failure and after the service recovery attempt have been measured. The participants were also asked to respond to Likert type questions to explain to explain how they felt about the service encounter they were exposed to in the scenarios. The analysis of data showed that although attractiveness reduced the negative of the responses, increased interest in the attractive service employee. However, the results showed that in both scenarios (with attractive and less attractive service employee photos) the service recovery paradox did not occur.</p>

<p>This study is motivated by Robinson’s Cognition Hypothesis and aims to investigate the impact of task grading along reasoning demands dimension on syntactic complexity in English as foreign language writing. The participants of the study were 90 intermediate EFL learners from three intact classes at, and a Control group. At first, the students in all groups took part in the writing pre-test which was a picture story description task. Next, the treatment sessions including 8 sessions of picture description task performance began, during which the first experimental group received a series of picture description tasks in a randomized order of cognitive complexity. The second experimental group received the same tasks, but ordered from simple to complex based on their required reasoning demands. The control group, however, did not receive any picture description tasks; rather they received some typical writing activities and performed extra writing tasks from the course book. Finally, during the last session, the post- test was administered to all participants. The results of the data analysis through Analysis of Variances (ANOVA) using the SPSS software showed a significant positive impact for sequencing tasks from simple to complex on syntactic complexity of Iranian intermediate EFL learners.</p>

Published: December 2024

Background
The dropout rate of contact lens users has not decreased significantly over the years. Despite continuous improvements in contact lens (CL) designs, materials and surface treatments, the number of CL users who drop out remains similar to the number of new CL users. The aim of this study is to analyse the improvement in contact lens-associated dry eye disease (CLADE), quantified with the OSDI questionnaire when changing maintenance system solution from multipurpose solution to hydrogen peroxide.

Methods
This study included contact lens users for over a year as the multipurpose solution for the maintenance system, suffering from CLADE, and those who scored over 13 in the ocular surface disease index questionnaire, and did not manifest any clinical signs over 3 in the EFRON scale. The non-parametric data distribution was verified with the Kolmogorov-Smirnov test and Wilcoxon signed-rank test, which was used to compare the visual acuity (VA), OSDI score and bulbar redness (EFRON scale) of the follow-up visit against the baseline value.

Results
Thirty-eight patients were included. Analysing the clinical parameters between the initial and final visit after one month of hydrogen peroxide use, a statistically significant improvement was found in the VA, bulbar hyperemia, OSDI scale and their subscales of the total sample (P < 0.04).

Conclusion
This study is intended as a first step towards a standardised protocol of actions to improve CLADE in an attempt to reduce contact lens dropout using OSDI as a tool for detection.
Interspecies differences in the transcriptome response of corals to acute heat stress
Authors: Da-Anoy Jeric , Posadas Niño , Conaco Cecilia 
Published: December 2024

Rising sea surface temperatures threaten the survival of corals worldwide, with coral bleaching events becoming more commonplace. However, different coral species are known to exhibit variable levels of susceptibility to thermal stress. To elucidate genetic mechanisms that may underlie these differences, we compared the gene repertoire of four coral species, Favites colemani, Montipora digitata, Acropora digitifera, and Seriatopora caliendrum, that were previously demonstrated to have differing responses to acute thermal stress. We found that more tolerant species, like F. colemani and M. digitata, possess a greater abundance of antioxidant protein families and chaperones. Under acute thermal stress conditions, only S. caliendrum showed a significant bleaching response, which was accompanied by activation of the DNA damage response network and drastic upregulation of stress response genes (SRGs). This suggests that differences in SRG orthologs, as well as the mechanisms that control SRG expression response, contribute to the ability of corals to maintain stability of physiological functions required to survive shifts in seawater temperature.

Published: September 2019

ObjectiveUse an established quality improvement method, Lean A3, to improve the process of opioid prescribing in an academic rheumatology ambulatory clinic.MethodsThis retrospective pre‐postintervention analysis of rheumatology records included patients prescribed opioids at least once during the study period. Lean A3 was used to develop a Controlled Substance Visit Protocol to standardize eight recommended elements of the opioid prescribing workflow. Analyses included changes in the recommended workflow elements and changes in opioid prescribing volume.ResultsImprovements were observed in seven of the eight recommended elements. Patient education, including treatment agreements and consent forms (39% completion for both preimplementation) increased to 78% and 80%, respectively (P < 0.001 for both). Risk assessment, as measured by the Current Opioid Misuse Measure, increased from 0.5% to 76% (P < 0.001). Best practices in prescribing, including prescribing in multiples of seven to avoid weekend refill requests, increased from 1% to 79% (P < 0.001). Monitoring parameters, including standardized functional assessment (0% vs. 86%), prescription drug monitoring program queries (49% vs. 84%), and urine testing (1% vs. 32%) all increased (P < 0.001). Visits scheduled at least quarterly for patients on chronic opioids did not change (P = 0.18). Overall, the number of patients prescribed opioids (185 vs. 160; P < 0.001) and annual prescription opioid morphine milligram equivalents (MMEs) (1 933 585 MME vs. 1 386 368 MME; P < 0.001) decreased.ConclusionThe Lean A3 method is a successful quality improvement tool for improving and sustaining opioid prescribing within a single academic rheumatology clinic. This method has potential applicability to similar clinics interested in improving opioid prescribing.

AbstractDeveloping efficient interfacial hole transporting materials (HTMs) is crucial for achieving high‐performance Pb‐free Sn‐based halide perovskite solar cells (PSCs). Here, a new series of benzodithiophene (BDT)‐based organic small molecules containing tetra‐ and di‐triphenyl amine donors prepared via a straightforward and scalable synthetic route is reported. The thermal, optical, and electrochemical properties of two BDT‐based molecules are shown to be structurally and energetically suitable to serve as HTMs for Sn‐based PSCs. It is reported here that ethylenediammonium/formamidinium tin iodide solar cells using BDT‐based HTMs deliver a champion power conversion efficiency up to 7.59%, outperforming analogous reference solar cells using traditional and expensive HTMs. Thus, these BDT‐based molecules are promising candidates as HTMs for the fabrication of high‐performance Sn‐based PSCs.
The Effects of Side Chains on the Charge Mobilities and Functionalities of Semiconducting Conjugated Polymers beyond Solubilities

Published: September 2019

AbstractRecent decades have witnessed the rapid development of semiconducting polymers in terms of high charge mobilities and applications in transistors. Significant efforts have been made to develop various conjugated frameworks and linkers. However, studies are increasingly demonstrating that the side chains of semiconducting polymers can significantly affect interchain packing, thin film crystallinity, and thus semiconducting performance. Ways to modify the side alkyl chains to improve the interchain packing order and charge mobilities for conjugated polymers are first discussed. It is shown that modifying the branching chains by moving the branching points away from the backbones can boost the charge mobilities, which can also be improved through partially replacing branching chains with linear ones. Second, the effects of side chains with heteroatoms and functional groups are discussed. The siloxane‐terminated side chains are utilized to enhance the semiconducting properties. The fluorinated alkyl chains are beneficial for improving both charge mobility and air stability. Incorporating H bonding group side chains can improve thin film crystallinities and boost charge mobilities. Notably, incorporating functional groups (e.g., glycol, tetrathiafulvalene, and thymine) into side chains can improve the selectivity of field‐effect transistor (FET)‐based sensors, while photochromic group containing side chains in conjugated polymers result in photoresponsive semiconductors and optically tunable FETs.

AbstractAdvances in material science and nanotechnology have fostered the miniaturization of devices. Over the past two decades, the form‐factor of these devices has evolved from 3D rigid, volumetric devices through 2D film‐based flexible electronics, finally to 1D fiber electronics (fibertronics). In this regard, fibertronic strategies toward wearable applications (e.g., electronic textiles (e‐textiles)) have attracted considerable attention thanks to their capability to impart various functions into textiles with retaining textiles' intrinsic properties as well as imperceptible irritation by foreign matters. In recent years, extensive research has been carried out to develop various functional devices in the fiber form. Among various features, lighting and display features are the highly desirable functions in wearable electronics. This article discusses the recent progress of materials, architectural designs, and new fabrication technologies of fiber‐shaped lighting devices and the current challenges corresponding to each device's operating mechanism. Moreover, opportunities and applications that the revolutionary convergence between the state‐of‐the‐art fibertronic technology and age‐long textile industry will bring in the future are also discussed.

Published: September 2019

AbstractElectrolyte‐gated transistors (EGTs) represent an interesting alternative to conventional dielectric‐gating to reduce the required high supply voltage for printed electronic applications. Here, a type of ink‐jet printable ion‐gel is introduced and optimized to fabricate a chemically crosslinked ion‐gel by self‐assembled gelation, without additional crosslinking processes, e.g., UV‐curing. For the self‐assembled gelation, poly(vinyl alcohol) and poly(ethylene‐alt‐maleic anhydride) are used as the polymer backbone and chemical crosslinker, respectively, and 1‐ethyl‐3‐methylimidazolium trifluoromethanesulfonate ([EMIM][OTf]) is utilized as an ionic species to ensure ionic conductivity. The as‐synthesized ion‐gel exhibits an ionic conductivity of ≈5 mS cm−1 and an effective capacitance of 5.4 µF cm−2 at 1 Hz. The ion‐gel is successfully employed in EGTs with an indium oxide (In2O3) channel, which shows on/off‐ratios of up to 1.3 × 106 and a subthreshold swing of 80.62 mV dec−1.

Published: September 2019

AbstractThe direct asymmetric α‐hydroxylation of β‐dicarbonyl compounds has been developed using cinchona‐derived phase‐transfer catalysts in batch and semi‐flow processes. Using visible light as the driving force and air as oxidant, the corresponding products were obtained in excellent yields (up to 96%) and good enantioselectivities (up to 90% ee). The catalyst acts as a chiral center and a catalytic center and forms a chiral enolate complex with the substrate to act as a photosensitive center in the reaction. The use of semi‐flow photochemical processes allowed a reduction in reaction time (24 h to 0.89 h) and good yields (up to 93%) and enantioselectivities (up to 88% ee) were obtained.magnified image

Published: September 2019

AbstractSome thermodynamic and mechanical properties of a polyolefin, such as the melting temperature and the rigidity, are dependent on the nature of its sequence distribution. Accurate modeling of sequence length distribution (SLD) is important in precisely tuning and optimizing the properties of polymers produced. In this article, we proposed a model to predict the molecular weight distribution (MWD) and SLD for olefin copolymerization with vanadium‐based catalyst. Due to the 2,1‐insertion of α‐olefin with vanadium‐based catalyst, the SLD is expressed by uninterrupted methylene sequence distribution instead of conventional triad sequence distribution. To obtain a reliable model, parameter estimation with experimental data is first conducted. The SLD model along with the estimated kinetic parameters can be used to predict unmeasurable sequence length fraction. For the experimental conditions studied, the average methylene sequence length is predicted to change from 10 to 4 units as the propylene/ethylene mole feed ratio increases from 1.1 to 3.4.

Published: September 2019

ABSTRACTMost polymer‐based materials do not exhibit ultraviolet (UV) protection or wear resistance properties, thereby leading to poor packaging functions. This study provides an approach that simultaneously improves the UV protection and tribological functions of melt‐processed polyamide (PA)‐based composites by the addition of in‐house produced hexagonal‐shaped nano‐zinc oxide (ZnO) particles. The 5 wt % ZnO‐filled PA composite exhibited significant photodegradation protection (84%) with a well‐balanced friction coefficient and wear resistance properties. The 1 wt % ZnO‐filled PA composite also exhibited significant photodegradation protection (84%) but with a lower friction coefficient and strong wear resistance, while the 7 wt % ZnO‐filled PA composite displayed strong photodegradation protection (94%) with poor wear resistance. The results suggest that owing to their UV stability and wear resistance, the low ZnO‐filled PA composites show great potential as plastic materials in different applications such as active packaging. In addition, all the ZnO‐filled PA composites exhibited improved mechanical properties relative to those of the neat PA. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48418.

Published: September 2019

AbstractThis paper describes the results of introducing an additional dynamic element to an anti‐windup compensator from control quality and stability area anslysis viewpoint. The analyzed system consists of a first‐order plant with time delay and a fractional‐order PI controller, to present the discussed approach. The controller is tuned based on Hermite‐Biehler and Pontryagin theorems. In the paper, the stability analysis and tracking performance are presented based on both simulation and experimental results. The experiments have been performed using Inteco Modular Servo System with performance evaluated on the basis of the selected performance criterion, namely the Integral of Absolute Error, to verify the applicability of the proposed method. The results have proven that use of the additional dynamic element provides a wider range of controller parameters to ensure stability of the closed‐loop system and better tracking performance in comparison to the system without anti‐windup compensation or system with a standard anti‐windup compensator. It is actually the first time that this type of analysis for dynamic element compensation in anti‐windup framework has been presented for fractional‐order systems. In addition, all the obtained results are referred to the experimental data.
