Gravitational waves from a curvature-induced phase transition of a Higgs-portal dark matter sector

The study of interactions between dark matter and the Higgs field opens an exciting connection between cosmology and particle physics, since such scenarios can impact the features of dark matter as well as interfering with the spontaneous breaking of the electroweak symmetry. Furthermore, such Higgs-portal models of dark matter should be suitably harmonised with the various epochs of the universe and the phenomenological constraints imposed by collider experiments. At the same time, the prospect of a stochastic gravitational wave background offers a promising new window into the primordial universe, which can complement the insights gained from accelerators. In this study, we examined whether gravitational waves can be generated from a curvature-induced phase transition of a non-minimally coupled dark scalar field with a portal coupling to the Higgs field. The main requirement is that the phase transition is of first order, which can be achieved through the introduction of a cubic term on the scalar potential and the sign change of the curvature scalar. This mechanism was investigated in the context of a dynamical spacetime during the transition from inflation to kination, while also considering the possibility for inducing electroweak symmetry breaking in this manner for a sufficiently low reheating temperature when the Higgs-portal coupling is extremely weak. We considered a large range of inflationary scales and both cases of positive and negative values for the non-minimal coupling, while taking into account the bound imposed by Big Bang Nucleosythesis. The resulting gravitational wave amplitudes are boosted by kination and thus constrain the parameter space of the couplings significantly. Even though the spectra lie at high frequencies for the standard high inflationary scales, there are combinations of parameter space where they could be probed with future experiments.

Selection of the Optimal Concentration of Nitro Blue Tetrazolium Dye in Polyvinyl Alcohol Film for Diagnostic Radiology

Ensuring the limited exposure of both patients and medical professionals to radiation during examinations is paramount. One effective approach is the utilization of a film dosimeter that is not only efficient but also easy to carry. In this research, we employed polyvinyl alcohol/nitro blue tetrazolium (PVA/NBT) with varying concentrations of NBT dye (ranging from 0.015 to 0.3 g) to identify the most optimal concentration. These films were subjected to low doses of gamma rays (8, 25, 55 and 96 mGy) emitted from 3 Cs-137 sources. XRF analysis confirmed the effectiveness of the preparation method used, and the NBT salt exhibited excellent solubility (R2 = 0.93). The films exhibited an increasing yellow hue as the concentration of NBT dye rose. Following irradiation, they took on a yellowish-brown tint, intensifying with higher gamma doses. PVA/NBT films, when stored in the dark, demonstrated good stability for 30 days post-irradiation. Analysis using ImageJ software unveiled that the relative density of the red color heightened proportionally with the concentration of NBT dye. XRD patterns showcased the clarity of structural rearrangements occurring after irradiation with high NBT concentrations. Two distinct peaks were registered at 2θ = 20.12 and 40.94 °, which shifted to 2θ = 19.74 and 41.30 ° post-gamma irradiation. The CIELab system study and K/S color strength indicated that increasing the NBT dye concentration led to a linear rise in color strength with escalating low gamma doses. Through a comprehensive assessment, it is concluded that PVA/NBT film can be effectively employed as a dosimeter for low gamma doses in diagnostic radiology. HIGHLIGHTS Nine different concentrations of NBT dye were used to prepare PVA/NBT films. The standard dose scale in diagnostic radiology (mGy) was applied in this work. CIELab system parameters showed a linear increase with increasing applied dose. XRD pattern recorded a shifted peak after irradiation from 2θ = 20.12 to 19.74 °. The dose-response was affected by increasing the NBT dye to a certain concentration. GRAPHICAL ABSTRACT

Job Involvement among ICDS Scheme Functionaries in India: Assessing Extension Needs for Enhanced Performance

Job involvement is psychological identification with one’s work as well as degree to which the job situation is central to person and his identity. Human behavior plays a pivotal role in maximizing organizational effectiveness irrespective of the technological support and their involvement in their job is critical for successful achievement of its objectives. ICDS (Integrated Child Development Services) is a comprehensive scheme of Govt. of India enriches human resource and tackles malnutrition and health problems in children below six years of age and their mothers. The services to the beneficiaries, who are pregnant women, Lactating Mothers, children under 5 years, adolescents and adult women, are provided at Centre called as Anganwadi. The grass-root level functionaries at the center are called Anganwadi workers (AWW) who executes ICDS scheme as per the Government guidelines to raise the level of health and nutrition, create proper mental, physical and social development of children below six years; to reduce mortality and malnutrition and dropouts. Since job involvement contributes to overall availability of human resource, the success of the ICDS programme extents to effective and successful working of AWWs. The study was conducted to know the job- involvement of AWWs and AWHs – the grass-root functionaries of ICDS scheme. The conducted in one of the blocks of Faizabad District situated in Eastern part of Uttar Pradesh state. One hundred AWWs were randomly selected from 182 AWWs in the block and administered interview schedule and standardized Job Involvement scale by Dr. A.P Singh. The data collected revealed that AWWs were highly involved (47%), moderately involved (37%) and rest (16%) had low involvement. Analysis further found that job involvement and income of the workers; educational qualification and work experience are significantly dependent.

Quality of information provided by artificial intelligence for assigned female at birth patients undergoing gender affirming surgery

Introduction. Artificial Intelligence has emerged as a transformative force across various industries, with a particularly profound impact on healthcare. It is well known that patients today increasingly turn to the internet searching for information about their medical conditions, utiliz-ing tools like AI-based chatbots. However, information from unverified sources can influence patients’ decisions regarding treatment options. This study aims to evaluate the quality of medical information provided by ChatGPT for Assigned Female At Birth (AFAB) patients considering gender-affirming surgery.Methods. Given the possibility that some patients might use ChatGPT as an information source for their medical conditions, specific ques-tions were posed to the chatbot in the same manner a patient inter-ested in gender-affirming surgery would. The quality of the information was assessed using the standardized EQIP scale. The survey involved 30 individuals: 15 plastic surgery residents and 15 non-healthcare pro-fessionals, with data collected in February 2023 and analyzed using SPSS Software version 28.0.Results. Separate surveys evaluated the quality of information provid-ed by ChatGPT regarding two primary procedures for AFAB patients undergoing gender-affirming surgery: phalloplasty and top surgery. The quality of the information was found to be adequate in both cases, with significant qualitative differences across the various survey sections. ChatGPT excelled in delivering information in a simple and accessible manner, earning high scores in the “Structured Data” area. However, the “Content Data” area, representing the completeness of information, was deemed sufficient. A significant deficiency was noted in the “Iden-tification Data” section, highlighting the absence of information about revisions, bibliographies, and the names of the entities or individuals providing content.Conclusions. ChatGPT demonstrated excellent capability in providing information in a straightforward and accessible manner, achieving high scores in the “Structured Data” area in both evaluations. The complete-ness of information, represented in the “Content Data” area, was con-sidered sufficient. However, a notable deficiency in the “Identification Data” section underscored the absence of details regarding revisions, bibliographies, and content authorship. Although the content score F.R. Grippaudo et al.2could be improved by adjusting the number and phrasing of questions, the lack of bibliography and source verification remains a significant limitation of this tool. ChatGPT offers advantages such as ease of communi-cation, privacy, anonymity, and overcoming language barriers; nonetheless, given its limitations, its role should always be seen as supplementary to that of the surgeon.

Impact of moral resilience and interprofessional collaboration on nurses' ethical competence.

Home care nurses are central in providing holistic and compassionate care to patients in home-based palliative care. Ethical caring competency is essential for home care to sustain nurses' integrity in the face of moral adversity. Interprofessional collaboration is vital for ensuring ethical decision-making and providing patient-centered care in home-based palliative care settings. This study explored the predictive roles of interprofessional collaboration and moral resilience on ethical caring competency among home care nurses in home-based palliative care. A cross-sectional survey of 400 nurses was conducted from October to December 2023, utilizing standardized scales to measure interprofessional collaboration, moral resilience, and ethical caring competency. A convenience sample of 400 home care nurses was also included in this study. Correlation and linear regression analysis were used to clarify the associative and predictive findings. Ethical approval from the ethics committee, institutional permission, and informed consent from the participants were obtained for data collection. Correlation analysis showed significant positive correlations between the ethical caring competency, interprofessional collaboration, and moral resilience constructs, with coefficients ranging from 0.482 to 0.967. Linear regression revealed that management of collaborative systems and total moral resilience significantly predict ethical caring competency, explaining 14.6% and 36.6% of its variance, respectively. Other variables, such as the effects of collaboration and communication, did not significantly influence ethical caring competency. The study highlights the significant impact of interprofessional collaboration, particularly the management of collaborative systems and moral resilience, on enhancing ethical caring competency among nurses. Enhancing interprofessional collaboration and moral resilience through targeted strategies in nursing practice and education can significantly improve ethical caring competencies. These efforts are essential for delivering high-quality, patient-centered care and for fostering a healthcare environment that respects the ethical principles guiding nursing practice.

SCAWA scales: A new digital tool for wrinkles clinical grading based on AI.

Clinical assessment of wrinkle depth is essential for efficacy evaluations of anti-ageing products. Standardized photographic scales, representative of different wrinkle depths are often used by experts to assign subjects reliable grades. These tools, based on real pictures, usually exist as hard copies (printed books or sheets) for invivo gradings. Our project aims at developing a methodology to create digital standardized computer-generated scales, allowing photograph and real-life gradings, and providing raters with greater comfort, accessibility, and flexibility in their construction, thanks to the artificial intelligence significative contribution. A completely new approach, based on machine learning, allows the creation of Standardized ColorFace® AI-based Wrinkle Assessment (SCAWA) scales. Instead of using real photographs, the scale images are computer-generated. A generative adversarial network (GAN) is trained to create realistic wrinkle samples that are finely controllable by exploring the GAN latent space. Finally, the scale images are selected among hundreds of artificial images depicting natural wrinkle appearances, such as the illustrated wrinkle evolution is well-detailed (small gaps between grades), morphologically stable, and mathematically linear according to a criterion of wrinkle conspicuous depth. The created 12-point scale for crow's feet wrinkle evaluation on ColorFace® pictures is proven to be realistic, linear, and robustly and accurately usable for photograph assessments. The scale coherence in terms of image ranking has been validated, as well as its reliability and acceptability in real conditions of use. Additionally, the wrinkle grades obtained by the SCAWA scale are well correlated (R = 0.94) with the ones obtained by the Skin Aging Atlas on the same pictures. The AI methodology and digital format brought also interesting side results, such as an enhanced harmonization between experts and a higher representativeness, that is, a decrease of out-of-range pictures. SCAWA scale makes the most of machine learning to provide an innovative digital tool to ease wrinkles in visual assessment of pictures, while optimizing linearity, homogeneity, and accuracy aspects. The experts' enthusiastic feedback about the scale format and quality is promising regarding the adaptation of the methodology to other signs and a larger distribution of this tool in the market of cosmetic product efficacy assessment.

Cyanotic heart defects in children: neurological aspects of the problem

Background. The goal is to justify the need to monitor neurodevelopment in children with congenital heart defects (CHD) and to study neurological disorders in patients under 3 years of age with cyanotic heart defects. Materials and methods. Modern research on the neurodevelopment of children with CHD were analyzed. Sixty-two patients with cyanotic heart defects who underwent examination and surgical treatment at the Center for Pediatric Cardiology and Cardiac Surgery of the Ministry of Health of Ukraine were studied. They are divided into 2 groups: group 1 are children with critical cyanotic CHD and group 2 — with non-critical cyanotic CHD. The control group consisted of 35 healthy patients. A neurological examination was performed using standardized neurological scales. Data processing was carried out using the Stata 12.1 licensed statistical package. Results. Neurodevelopmental disorders were diagnosed in 33 (53 %) of 62 children with cyanotic CHD: in group 1 — in 29 % of cases and in group 2 — in 24 %. These groups were statistically homogeneous in terms of gestational age (p = 0.492) and body weight at birth, with no significant difference from the control group. Older age is characterized mainly by delays in the stages of motor development (16 % in group 1 and 15 % in group 2) and speech disorders (7 % in group 1 and 3 % in group 2). Acute disorders of cerebral circulation (6 % in group 2) and the presence of epileptic seizures (up to 3 %) were characteristic of children under 1 year. Apgar score was lower in patients with critical cyanotic CHD with neurodevelopmental delay and a longer duration of artificial circulation during surgical treatment. Conclusions. 1. Neurological disorders were diagnosed in 53 % of patients with cyanotic heart defects: in 29 % with critical heart defects and 24 % with non-critical heart defects. 2. Older children are characterized mainly by delays in the stages of motor development and speech disorders. Behavioral disorders are more typical for children with non-critical CHD. Acute disorders of cerebral circulation and the presence of epileptic seizures were characteristic of children under 1 year of age. 3. The influence of body weight and gestational age on neurodevelopmental disorders is excluded. The severe state of children with neurodevelopmental delay at birth and an increase in the duration of artificial circulation during surgical treatment were found. 4. Interdisciplinary examination of patients with cyanotic heart defects, including examination by a pediatric neurologist, as well as a follow-up is necessary for timely referral to the next stages of rehabilitation.

Validation of the International REM Sleep Behavior Disorder Study Group Symptoms Severity Scale (IRBD-SSS): a new tool to assess RBD clinical severity.

Currently, no standard scale has been validated to assess overall severity of RBD symptoms in the home environment. We aimed to evaluate the psychometric properties of the International RBD Severity Scale (IRBD-SSS), a new tool designed by the International RBD Study Group. Two versions of the IRBD-SSS were created, one for the patient (IRBD-SSS-PT) and another for the bedpartner (IRBD-SSS-BP), both consisting of 3 components, namely vocalizations, body movements and injury, with a fourth component (patient version only) evaluating dream content. To score each dimension, the frequency and severity/impact of behaviors during the previous month are multiplied. Psychometric properties of the IRBD-SSS were assessed, including reproducibility. A total of 188 subjects including n = 132 RBD patients (n = 94 isolated RBD and n = 38 symptomatic RBD) and n = 52 bedpartners were enrolled from eight Sleep centers across France and Italy. Participants completed the scale at baseline and after one week. Acceptability of the scale was excellent in patients (97%) and bedpartners (98%). Internal consistency was acceptable for IRBD-SSS-PT (Cronbach α = 0.75) while slightly low for IRBD-SSS-BP (Cronbach α = 0.49). Concurrent validity was good for both patient (r = 0.70;p < 0.001, see Figure) and bedpartner (r = 0.69;p < 0.001) IRBD-SSS. Reproducibility was high for IRBD-SSS-PT (Lin's coefficient of agreement = 0.85 [0.81;0.90]) and good for the IRBD-SSS-BP (0.79 [0.68;0.90] (p < 0.001). Both the patient and bedpartner versions of the IRBD-SSS showed excellent acceptability, acceptable internal consistency, good external validity and high reproducibility. IRBD-SSS is a useful tool to test the severity of RBD symptoms in clinical settings and clinical trials. NCT04071899.

Heat stress during reproductive development inhibits fertilization in olives

In this study, we investigated the effect of heat exposure during olive inflorescence on reproductive development. We hypothesized that male development processes during this period are particularly sensitive to high temperatures. We characterized the development of flowers and inflorescences under natural conditions in the cultivars 'Arbequina' and 'Koroneiki', and defined eight phenological stages, beginning with the emergence of reproductive buds until anthesis (international standard BBCH scale of the phenological inflorescence development phases 53–60). In addition, we examined the response of olive inflorescence and flowering, to two heat scenarios: prolonged exposure to moderately high temperatures and a two-hour concentrated heat shock treatment. Analysis of our data revealed that both treatments had a detrimental effect on the development and functioning of the tapetum, the innermost layer of the anther, which is essential for the development and functioning of pollen. Additionally, we found that the 'Arbequina' cultivar displayed relative tolerance to heat compared to 'Koroneiki' in terms of pollen germinability after heat stress. In contrast to the response of the above cultivars, the 'Souri' exhibited an exceptionally high sensitivity to heat. An assessment of pollen viability after in vitro heat shock treatment of 54 cultivars revealed that pollen from seven varieties, 'Niedda de Oliana', 'Lechín de Sevilla', 'Tonda Oliana', 'Tamir', 'Sigoise', 'Taggiasca', and 'Carrasquenha', showed exceptional tolerance to heat. These cultivars show a greater degree of suitability for cultivation in warm climates, (or in areas susceptible to extreme hot-spells). This study demonstrated that heat has a negative impact on the male reproductive system in olives, during early flower development and in mature pollen grains, which are relatively resistant to heat. Heat stress impaired pollen tube elongation capacity, and germination rate. Additionally, heat stress affected the ultrastructure of the external wall of the pollen grain, the exine, potentially impairing its ability to adhere to the stigma and fertilize the ovule. The sensitivity of olive reproductive capacity to heat is a genotype-dependent trait, allowing for the identification of heat-resistant cultivars for use as pollen donors and for development of new heat-resistant cultivars.

“Distress is probably the wrong word”: exploring uncertainty and ambivalence in non-clinical voice-hearing and the psychosis continuum

ABSTRACT Background Non-clinical voice-hearers (NCVHs) have been the subject of a growing body of psychological research, a primary aim of which is the development of new therapeutic techniques to support those who struggle with voice-hearing. However, relatively little research has examined non-clinical voice-hearing experiences beyond their relationship with clinical voice-hearing. Methods The present study consists of a qualitative re-analysis of 17 semi-structured interviews conducted as part of an NCVH neuroimaging study which included items from the Psychotic Symptoms Rating Scale (PSYRATS) and Positive and Negative Syndrome Scale (PANSS). Results were generated using thematic analysis. Results Analysis of interview responses showed that participants often experience negative voice content and negative emotion, but have frameworks which normalize a range of voice-hearing experiences. Participants also reported experiences which are not captured by standard clinical scales, as well as reporting comfort with uncertainty and ambiguity surrounding voices. Discussion These results indicate that much of the experience of NCVHs may be missed by clinical measures and concepts, suggesting a need to approach them in ways that go beyond typical understandings of the psychosis continuum.

Health-related quality of life and self-care in heart failure patients under telecare-insights from the randomized, prospective, controlled AMULET trial.

The growing population of heart failure (HF) patients places a burden on the healthcare system. Patient-centered outcomes such as health-related quality of life (HRQoL) and self-care behaviors are key elements of modern HF management programs. Thus, optimized strategies to improve these outcomes are sought. To assess the effects of a new model of medical telecare on HRQoL and self-care in patients with HF (the AMULET study). The study was prospective, randomized, open-label, and controlled with two parallel groups: telecare and standard care. In the telecare group, HF nurses performed patient clinical assessments with telemedical support by a cardiologist and provided education focused on the prevention of HF exacerbation. In the standard care group, patients were followed according to standard practices in the existing healthcare system. At the baseline and at 12 months, HRQoL was assessed using the Short Form 36 (SF-36) questionnaire and the Minnesota Living with Heart Failure Questionnaire (MLwHF). The level of self-care was assessed with the 12-item standardized European Heart Failure Self-care Behavior Scale (EHFScBS-12). In the overall study group, 79% of the subjects were male, the mean age was 67 ± 14 years, and 59% of the subjects were older than 65 years of age. The majority of the subjects (70%) had a left ventricular ejection fraction below 40%. After 12 months, statistically significant increases in physical component of the SF-36 (43.3 vs. 47.4 for telecare vs. 43.4 vs. 46.6 for standard care) and mental component of SF-36 (58.4 vs. 62 for telecare vs. 60.4 vs. 64.2 for standard care) were noted, with no intergroup differences. However, patients receiving telecare showed improvement in specific domains, such as physical functioning, role-physical, bodily pain, vitality, social functioning, role-emotional, and mental health. There was a significant decrease in MLwHF (29 vs. 35.0; lower is better) at follow-up for both groups. Telecare patients had a statistically significant decrease in EHFScBS-12 (lower is better) at 12 months. AMULET outpatient telecare, which is based on nurse-led non-invasive assessments supported by specialist teleconsultations, improved the HRQoL and self-care of HF patients after an episode of acute HF.

Body image of postmenopausal women

Abstract: Body image is a multidimensional, subjective, and dynamically changing concept that includes personal perceptions and feelings towards one's body. Menopause is associated with significant changes in external appearance and physical functioning. Aim: The study aimed to determine how women of postmenopausal age assess their bodies and what factors influence this evaluation. Material and methods: The research was conducted in six randomly selected gynaecological and primary health care clinics in Lublin. A total of 510 women were included in the study. A diagnostic survey was used as the research method. The research tool was a questionnaire consisting of a self-constructed part (socio-demographic data) and a standardized Body Esteem Scale questionnaire (BES). Results: In all subscales (sexual attractiveness, body control, and physical fitness), average results were obtained, although the highest was about body weight control (M = 5.85±2.00) and the lowest was related to sexual attractiveness (M = 4.78±2.17). The values of all subscales were significantly differentiated by the subjective assessment of the participant's health status (p&lt;0.05). The values of sexual attractiveness were significantly related to the place of residence (p = 0.021) and the employment status of the participants (p = 0.030). The values of self-assessment of physical fitness were significant with the place of residence (p = 0.012) and the marital status of the participants (p&lt;0.001). Conclusion: Women in postmenopausal age perceive their bodies in all categories (sexual attractiveness, body weight control/body strength, physical fitness) at an average level, indicating the need for psychosocial support. Providing them with support with their self-acceptance, and perhaps lifestyle changes, may improve their self-esteem to their body image.

Development of DRIP - drought representation index for CMIP climate model performance, application to Southeast Brazil

With the escalating impacts of drought events driven by climate change, reducing the uncertainty of drought projections becomes critical for enhancing risk management and adaptation strategies. This study aimed to develop an index for assessing the performance of CMIP6 Global Climate Models in simulating meteorological drought scenarios across regional hydrological systems, intended to provide more reliable information for management purposes. Named the ‘Drought Representation Index for CMIP Climate Model Performance’ (DRIP), this index evaluates CMIP models' performance to represent drought severity, duration, and return period. DRIP was used to select CMIP models and create an ensemble of the best-performing models (E-DRIP) to improve the reliability of drought projections. E-DRIP was then compared with a general ensemble of available CMIP6 models (E-CMIP). We applied this method in Southeast Brazil, a region known for its climate uncertainties and low predictability; specifically, it was implemented within the Paraíba do Sul River Basin, a nationally strategic watershed in a highly populated and industrialized area, which has recently faced unprecedented drought-related water crises. Results showed that DRIP effectively assessed the individual performance of CMIP models, which exhibited considerable variability, and identified the top-performing models for a multi-model ensemble. Additionally, the E-DRIP ensemble significantly reduced uncertainties in drought projections, achieving an average reduction of 63 % in the study area compared to E-CMIP. Furthermore, the proposed method enables evaluations across any standardized drought index scale, reference period, or threshold, and can be readily adapted to other hydrological systems.

Exploring MBH–P scaling relations in spiral galaxies: a comparative analysis of inner and outer arm structures

ABSTRACT We study the galactic spiral arm pitch angle dependence with wavelength as predicted by the density wave theory. A sample of 10 barred and unbarred spiral galaxies with two distinct, well-defined arms is used for the measurements. The data sample consists of galaxies with inner arms and galaxies with both inner and outer arms. We use six wavebands, namely 3.6 $\mu$m, 8.0 $\mu$m, B band, H $\alpha$, H i, and CO for the image analysis. The pitch angles are visually measured with the python-ol script and more precise measurements are obtained using spirality. We find a 1:1 correlation between pitch angle measurements in the 3.6 and 8.0 $\mu$m bands. We predict supermassive black hole (SMBH) masses for 3.6 $\mu$m waveband pitch angles using a standard scaling relation. We find that the black hole mass of a galaxy with both inner and outer arms is determined by the average pitch angle of the inner arms. Using only galaxies with inner arms, we find an SMBH mass–pitch angle relation of $\log (M_{\rm BH}/\mathrm{M}_\odot)=(7.11 \pm 0.33)+(0.003 \pm 0.017){\textit P}$. Using only galaxies with both inner and outer arms, we find an SMBH mass–pitch angle relation of $\log (M_{\rm BH}/\mathrm{M}_\odot)=(7.56 \pm 0.28)-(0.038 \pm 0.013){\textit P}$.

Epidemiology and Functional Outcome of Acute Stroke Patients in Korea using Nationwide data.

Korea's healthcare system and policy promotes early, actively stroke treatment to improve prognosis. This study represents stroke epidemiology and outcomes in Korea. This study investigated data from the Acute Stroke Assessment Registry. The registry collects data from over 220 hospitals nationwide, focusing on quality stroke service management. Data analysis included patient demographics, stroke severity assessment, and discharge prognosis measurement using standardized scales. 86,568 acute stroke patients were collected with demographic and clinical characteristics during 18 months from 2016 to 2021, focusing on acute subarachnoid hemorrhage, acute intracerebral hemorrhage, and acute ischemic stroke. Of these 86,568 patients, 8.3% was subarachnoid hemorrhage, 16.3% intracerebral hemorrhage, and 74.9% ischemic stroke. Trends showed decreasing subarachnoid hemorrhage and increasing intracerebral hemorrhage cases over the years. 68.3% stroke patients had the clear onset time. 49.6 % stroke patients arrived within 4.5 hours of symptom onset, with more treated at general hospitals. Good functional outcomes at discharge was obtained with 58.3% of acute stroke patients, 55.9% of subarachnoid hemorrhage patients, 34.6% of intracerebral hemorrhage patients, and 63.8% of ischemic stroke patients. The results showed that ischemic stroke was the most common subtype, followed by intracerebral hemorrhage and subarachnoid hemorrhage. Prognosis differed among subtypes, with favorable outcomes more common in ischemic stroke and subarachnoid hemorrhage compared to intracerebral hemorrhage.

The Effectiveness of Spiritual Group Therapy on Psychological Well-Being and Self-Efficacy of Patients with Type 2 Diabetes in Tehran in 2023

Introduction: Diabetes, as one of the common causes of mortality worldwide, extends beyond physical aspects and can impact psychological and emotional dimensions as well. Therefore, the present research aimed to determine the effectiveness of spiritual therapy on the psychological well-being and self-efficacy of patients with type 2 diabetes in Tehran. Methods: This study was a semi-experimental research with a pretest-posttest and a three-month follow-up design with a control group. The study population consisted of all the patients with type 2 diabetes who attended treatment centers in Tehran (Masih Daneshvari, Nikan, and the Iranian Diabetes Association) from August to November 2023. Among the patients, 37 were selected using purposive sampling and were randomly assigned to two groups: the experimental group (N=18) and the control group (N=19). The data collection tools included a demographic information form, the standardized Ryff's scale of psychological well-being– short form (Cronbach's alpha= 0/72), and the General Self-Efficacy Scale (Cronbach's alpha= 0/83). Data analysis was conducted using SPSS-21 software. Additionally, given the different stages of measurement (pre-test, post-test, and follow-up), repeated measures ANOVA was used for data analysis. Results: The results indicated that spiritual therapy led to an increase in psychological well-being (F=132/56, P&lt;0/001) and self-efficacy (F=15/51, P&lt;0/001) in patients with type 2 diabetes. Furthermore, the effect size of spiritual therapy on psychological well-being was 79%, and self-efficacy was 31%, and the sustainability of its effects was observed up to three months after treatment. Conclusion: The findings suggest the impact of spiritual therapy on enhancing psychological well-being and self-efficacy in patients with type 2 diabetes. Therefore, it is recommended that, in addition to the routine treatment of patients with type 2 diabetes, spiritual therapy be utilized to enhance the psychological well-being of the patients.

Synthesis and Mechanism of a Green Scale and Corrosion Inhibitor.

A new green water treatment agent, a poly(aspartic acid)-modified polymer (PASP/5-AVA), was synthesized using polysuccinimide and 5-aminovaleric acid (5-AVA) in a hybrid system. The structure was characterized, and the scale and corrosion inhibition performance were carried out with standard static scale inhibition and electrochemical methods, respectively. The mechanism was explored using XRD, XPS, SEM, and quantum chemistry calculations. The results indicated that PASP/5-AVA exhibited better scale and corrosion inhibition performance than PASP and maintained efficacy and thermal stability of the scale inhibition effect for a long time. Mechanistic studies indicated that PASP/5-AVA interferes with the normal generation of CaCO3 and CaSO4 scales through lattice distortion and dispersion, respectively; the combined effect of an alkaline environment and terminal electron-withdrawing -COOH groups can induce the stable C- ionic state formation in -CH2- of the extended side chain, thus enhancing its chelating ability for Ca2+ ions. At the same time, the extension of the side chain length also enhances the adsorption ability of the agent on the metal surface, forming a thick film and delaying the corrosion of the metal surface. This study provides the necessary theoretical reference for the design of green scale and corrosion agents.

AI-Powered Telemedicine for Automatic Scoring of Neuromuscular Examinations.

Telemedicine is now being used more frequently to evaluate patients with myasthenia gravis (MG). Assessing this condition involves clinical outcome measures, such as the standardized MG-ADL scale or the more complex MG-CE score obtained during clinical exams. However, human subjectivity limits the reliability of these examinations. We propose a set of AI-powered digital tools to improve scoring efficiency and quality using computer vision, deep learning, and natural language processing. This paper focuses on automating a standard telemedicine video by segmenting it into clips corresponding to the MG-CE assessment. This AI-powered solution offers a quantitative assessment of neurological deficits, improving upon subjective evaluations prone to examiner variability. It has the potential to enhance efficiency, patient participation in MG clinical trials, and broader applicability to various neurological diseases.

Explosive percolation in finite dimensions

Explosive percolation (EP) has received significant research attention due to its rich and anomalous phenomena near criticality. In our recent study [], we demonstrated that the correct critical behaviors of EP in infinite dimensions (complete graph) can be accurately extracted using the event-based method, with finite-size scaling behaviors still described by the standard finite-size scaling theory. We perform an extensive simulation of EPs on hypercubic lattices ranging from dimensions d=2 to 6, and find that the critical behaviors consistently obey the standard finite-size scaling theory. Consequently, we obtain a high-precision determination of the percolation thresholds and critical exponents, revealing that EPs governed by the product and sum rules belong to different universality classes. Remarkably, despite the mean of the dynamic pseudocritical point TL deviating from the infinite-lattice criticality by a distance determined by the d-dependent correlation-length exponent, TL follows a normal (Gaussian) distribution across all dimensions, with a standard deviation proportional to 1/V, where V denotes the system volume. A theoretical argument associated with the central-limit theorem is further proposed to understand the probability distribution of TL. These findings offer a comprehensive understanding of critical behaviors in EPs across various dimensions, revealing a different dimension-dependence compared to standard bond percolation.

The relationship between the Dark Triad and academic burnout mediated by perfectionistic self-presentation

Individuals with dark personality traits are more prone to burnout, but this was not yet investigated in academia. Perfectionistic self-presentation (PSPS), an interpersonal expression of perfectionism, could be an explaining factor. Therefore, we investigated the relationship between the dark triad (Machiavellianism, vulnerable and grandiose narcissism, and psychopathy) and academic burnout, and whether the PSPS total score and its dimensions (perfectionistic self-promotion, nondisplay of imperfection, and nondisclosure of imperfection) mediates this. We expected that higher dark triad traits would be associated with higher academic burnout and that this would be explained by higher PSPS. Hypotheses included expectations for each PSPS dimension as well. Questionnaires were completed by 304 bachelor/master students (Mage = 22.81 years). Mediations were performed for each dark triad trait with total PSPS and each of its dimensions separately as mediator, and academic burnout as dependent variable. Total PSPS and almost all of its dimensions positively and significantly mediated the relation between Machiavellianism as well as psychopathy and academic burnout (small effect sizes). In contrast, only the PSPS dimension nondisplay of imperfection was a significant, positive mediator of the relation between grandiose narcissism and academic burnout (medium effect size). The other mediations with grandiose or vulnerable narcissism were non-significant. Future research should investigate this further, for instance by using the standard dark triad scales. Finally, this study offers insights for interventions and prevention of academic burnout by highlighting the unique impact of each dark triad trait. For example, those high on Machiavellianism may benefit from tools to deal with cynicism and perfectionism, ultimately lowering the risk for academic burnout.
