Abstract
In our investigation, we pioneer the development of geometrically deformed strange stars within the framework of teleparallel gravity theory through gravitational decoupling via the complete geometric deformation (CGD) technique. The significant finding is the precise solution for deformed strange star (SS) models achieved through the vanishing complexity factor scenario. Further, we introduce the concept of space-time deformation caused by dark matter (DM) content in DM haloes, leading to perturbations in the metric potentials

Abstract
Studies of accretion disc luminosities and quasiperiodic oscillations around black holes may help us understand the gravitational properties of black hole spacetime. This work is devoted to studying the radiation properties of the accretion disk around the black holes in Kalb–Ramond gravity. We investigate the event horizon of the black hole spacetime and calculate the effective gravitational mass of the spacetime. Also, we analyze the circular motion of test particles in the black hole spacetime. The effects of the black hole charge and KR parameters on the particles’ effective mass, energy, and angular momentum at circular orbits and innermost stable circular orbits are studied. The frequency of Keplerian orbits and the radial and vertical oscillations of the particles along stable orbits are calculated and applied to analyze the existence of QPO in relativistic precession, warped disc, and epicyclic resonance models. QPO orbits’ locations with ratios of upper and lower frequencies of twin-peaked QPOs 3:2, 4:3, and 5:4 are analyzed compared to ISCO. We also obtain constrain values for the black hole mass, charge, KR field parameter, and QPO orbits found using Markovian chain Monte Carlo (MCMC) simulations for stellar mass (XTE J1550, GRS 1915+105), intermediate mass (M82-X1), and supermassive black holes (Sgr A*). Finally, we explore the radiative properties of the accretion disk around the charged black hole in KR gravity, such as the total radiation flux, accretion disc temperature, and differential luminosity.

Authors: Chen Yingying , Liu Qing , Tang Shi , Gan Zhenwei , Jia Xiaoyan , Yu Huimei 
Published: February 2025

Background: Cognitive decline is an important factor affecting the health and well‐being of older adults. Previous studies have shown that acrylamide (AA) caused neurological damage among occupationally exposed workers. However, the effect of AA on cognitive function in general older adults is unclear yet. Therefore, this cross‐sectional study is aimed at examining the relationships between blood markers of AA and cognitive function in the general elderly population.Methods: Four hundred sixty‐seven older adults (230 men and 237 women) aged 60 years and older from the National Health and Nutrition Examination Survey cycles (2013–2014) were included in this study. Logistic regression models were applied to explore the relationships between blood markers of AA and cognitive function.Results: After adjusting for all confounders, at the animal fluency test (AFT) dimension, the odds ratio (OR) for individuals in the highest tertile of hemoglobin (Hb) adducts of acrylamide (HbAA) and its metabolite glycidamide (hemoglobin adducts of glycidamide (HbGA)) were 0.251 (95% confidence interval (CI): 0.090, 0.699) and 0.354 (95% CI: 0.164, 0.761), respectively, compared with individuals in the lowest tertile, indicating that both HbAA and HbGA were negatively associated with the decline in cognitive function in dimension AFT. No significant associations were seen on other dimensions. Moreover, HbGA/HbAA had no association with any dimensions of cognitive decline.Conclusion: Collectively, our results suggest that HbAA and HbGA are not positively associated with cognitive decline in the general elderly population and are negatively related to the AFT dimension of cognitive impairment.

Published: February 2025

Abstract
In recent years, significant advancements have been made in smart and multifunctional materials through the integration of 4D printing and shape memory polymers (SMPs). This article highlights key SMP fabrication technologies for 4D printing, focusing on the functionality of stimuli-responsive polymers. Bio-based thermoplastic polyurethanes are produced through the prepolymer polymerization method, with 100% bio-based polyester polyols, polypropylene succinate, and 1,3-propanediol by corn sugar. The resulting SMTPU, which contains bio-polyol in the soft segment, along with a chain extender and isocyanate (4,4-methylene diphenyl diisocyanate, MDI), demonstrates excellent shape recoverability even after significant deformation. Atomic force microscopy, Fourier transform infrared spectroscopy, and X-ray diffraction were employed to analyze hydrogen bonding, microphase separation, and crystallinity, providing insights into the interactions between hard segments (HSs) and soft segments (SSs), an extent of phase separation, and a proportion of hydrogen-bonded urethane groups. The tensile strength of 15–21 MPa, elongation between 534 and 585%, and a hardness of 82–85 Shore A were shown. This study further explores the sustainability and unique properties of SMTPU, making it well-suited for shape memory applications at different temperatures with varying hard segment content. The findings are expected to contribute to future innovations and advancements in the field of 4D printing.

Abstract

Background
Obstructive sleep apnea (OSA) is a common condition in pediatrics that requires prompt recognition and management to minimize its negative impact on their health and development. Data on the prevalence of OSA among school-age minors in Jordan is scarce. This study aims to estimate the prevalence of OSA in children and adolescents and identify factors that make them more likely to have OSA and its impact on academic achievement.

Methods
This school‐based cross‐sectional study was conducted from January to March 2023. A questionnaire including information on demographic variables, school performance, and a validated sleep-related breathing disorder (SRBD) scale for pediatrics was distributed to 1798 students in schools all over Amman. The prevalence of OSA (defined as SRBD score > 33%) was reported as a proportion along with its 95% confidence interval.

Results
Out of the 2000 questionnaires distributed, 1798 were analyzed. Among these, 1079 (60%) were from children aged 5 to 10 years, and 719 (40%) were from adolescents aged 11 to 18 years. The prevalence of high risk for OSA (HR-OSA) was higher among adolescents than in children (25.6% vs. 20.8%). Adolescents with unemployed fathers were more likely to be HR-OSA (33.70 vs 17.57%, p < 0.001). In contrast, paternal employment did not affect the prevalence of HR-OSA in children. Sleep talking, bruxism, and sweating during sleep were more common among children with positive SRBD. Nocturnal enuresis (NE) was associated with positive SRBD in children and adolescents. HR-OSA was associated with poor academic performance in both study groups.

Conclusion
HR-OSA is highly prevalent in Jordanian children and adolescents. HR-OSA can occur alongside other sleep disorders, and it significantly impairs the academic performance of affected individuals. This study found an association between high risk for OSA and other sleeping disorders (sleep talking, sleep bruxism, and sweat during sleeping) and nocturnal enuresis which needs to be confirmed in larger studies.

Abstract
Morama bean [Tylosema escululetum (Burch.)] is a nutrient-dense underutilized legume that can address protein-energy and micronutrient malnutrition in developing countries. An ethnographic study using a snowball sampling method was conducted in Kweneng, Ghanzi, Southern, and Central districts of Botswana. The survey sought to gather and document information about demographic characteristics, traditional use, cultural norms, harvesting, processing, preservation, and health benefits of morama beans. A 5-point Likert-type scale was used to assess and rate the respondent(s) perceptions on traditional utilization and potential of the bean. The data was analyzed using Statistical Package for the Social Sciences (SPSS) and thematic grouping. It was found that morama bean is distributed in Botswana's sandy desert regions and is consumed by people who are native or migrated into these areas. Roasting in heated sand (mean = 4.93) and boiling fresh beans with water or milk (mean = 4.49) were the most popular methods of cooking morama beans. Across the four districts, morama bean was found to be an important component in traditional food and medicinal mixtures for undernourished infants, and expectant and lactating mothers, mostly prepared with soft porridge. Respondents cited a significant lack of scientific knowledge about the bean's medicinal properties (mean = 1.27–1.38), indicating the need for additional research. The nutritious density of morama beans (mean = 4.87) and their potential for processing into value-added products (mean = 4.10) were known to the respondents. As a result, the bean has a high potential to improve food and nutrition security in these communities.

Published: February 2025

Abstract

Background
Legal professionals frequently encounter forensic mental health issues in the criminal justice system. These issues can significantly impact the outcome of cases, making it essential to understand the attitudes and perceptions of these experts towards mental illness. While the literature has shown widespread stigma towards mental illness in the general population, there has been limited research focusing on the attitudes of judges and lawyers. This study aims to investigate the stigma related to mental health among Lebanese legal professionals. We sent an online questionnaire to judges and lawyers practicing in Lebanon. The survey included a section on socio-demographics and the following scales: Reported and Intended Behavior Scale (RIBS) which measures mental health stigma-related behavior and Perceived Devaluation and Discrimination Scale (PDDS) measuring the extent to which a person believes that most people will devalue or discriminate against someone with a mental illness.

Results
A total of 215 participants, with a mean age of 38.69 and a mean of 13.16 years of experience, completed the questionnaire. Most were females (62.8%) and worked as civil attorneys (47.4%). Only a minority received instruction on mental health or mental health law during training (10.7% and 8.8%). About a quarter believed their education on mental health issues was sufficient. Participants with positive attitudes (RIBS) were more likely to have a family member with a mental illness (p value = .001), feel comfortable handling cases involving mental health (p value = .001), and have lived with someone with a mental illness (p value = .007). Feeling educated about mental health issues was associated with lower perceived stigma on the PDDS (p value = .021).

Conclusions
The findings imply that enhancing mental health education and awareness within the legal profession could be a key strategy to reduce stigma and improve the overall treatment of individuals with mental health issues within the criminal justice system in Lebanon.

Aim. To study the expression of microRNA-16-5b, -27a, -34a-5p, -125b and -193b in melanoma tissue depending on the clinical and morphological characteristics of the tumor.Materials and methods. The study included 21 patients with a verified diagnosis of cutaneous melanoma. The expression of miR-16-5b, -27a, -34a-5p, -125b and -193b were studied in tumor tissue by real-time polymerase chain reaction. The patients are divided into 5 groups. The group 1 included patients with a tumor <0.75 mm thick (according to the Breslow classification), group 2 – 0.75–1.5 mm, group 3 – 1.51–3 mm, group 4 – 3–4 mm, group 5 – >4 mm. The control group consisted of 10 patients with skin nevi.Results. The expression of microRNA-27a-3p was reduced in group 5 compared to group 2 by 1.7 times. At the same time, the expression of microRNA-16-5b was, on the contrary, increased by 21.7 times in group 5 compared to groups 3 and 4. Multidirectional changes in microRNA expression were revealed when comparing parameters in groups differing in the depth of invasion. There was a 4.0-fold decrease in the expression of microRNA-27a in the group with Clark invasion III compared to the group with Clark invasion II, which was accompanied by an increase in the expression of microRNA-16-5b and microRNA-125 by 8.7 and 19.8 times, respectively. Moreover, the presence of signs of ulceration was associated with a low level of expression of microRNA-27a-3p against the background of an increase in the expression of the transcription factor microRNA-16-5b and microRNA-34a-5p.Conclusion. Thus, the features of microRNA expression in melanoma tissue have been identified. Changes in the expression of microRNA-27a-3p, -16-5b, -34a-5p and -125b are associated with the depth of its invasion and the presence of signs of invasive growth.

The use of bisphosphonates in medicine began in the 60s of the XX century due to their ability to prevent the dissolution of hydroxyapatite and thereby to reduce bone loss. Since the mid-80s of the XX century, they began to be regularly prescribed for hypercalcemia. Currently, the most used bisphosphonate is zoledronic acid. Indications for its use are osteoporosis, metastatic bone damage and hypercalcemia caused by a malignant tumor. Denosumab, which together with zoledronic acid belongs to the pharmacological group of osteomodifying agents, is also used in these pathologies. Thе drug is used to treat giant cell tumour.In the last 5 years, there has appeared the information on the use of bisphosphonates and denosumab to prevent aseptic instability, the most common complication of large joint endoprosthetics. According to the few data in the literature, significant improvement in periprosthetic bone mineral density is shown when using these drugs. Denosumab is more effective as compared to bisphosphonates. There is no reliable evidence of reduction in the risk of development of aseptic instability of the endoprosthesis with the use of bone-modifying agents. When prescribing bisphosphonates and denosumab, it is necessary to take into account adverse events associated with their use. In our opinion, using bone-modifying agents in patients after oncological endoprosthetics is reasonable in cases of high risk of aseptic instability. During primary endoprosthetics, their use should be avoided.The aim of the work is to assess the effect of BMA on the condition of the periprosthetic bone after endoprosthesis, as well as their effectiveness in preventing aseptic instability during oncological endoprosthesis of long bones.

Introduction. Skin melanoma, despite having similar clinical and histological characteristics, can have different prognoses. Gene expression profiling potentially allows for more accurate risk stratification of patients.Aim. To study prognostic test systems for assessing outcomes in patients with skin melanoma based on the analysis of primary tumors.Materials and methods. A systematic literature review (scoping review) was conducted in accordance with PRISMA-ScR principles. The search was performed in PubMed (2008–2024). Two independent reviewers conducted the study selection and data analysis to assess concordance. The data were presented descriptively.Results. Out of 149 identified publications, 31 studies were included in the review. The effectiveness of four test systems was evaluated, with the most frequently used being DecisionDx-Melanoma (19/31, 61.3%). This test stratifies patients by molecular classes: patients at high risk were found to have a 5.33 (±1.25) times higher likelihood of disease progression and poorer survival rates compared to lower-risk patients. No studies included data on the Russian population.Conclusions. Gene expression profiling demonstrates high accuracy in predicting outcomes for patients with skin melanoma.

Introduction. The use of modern adjuvant drug therapy in cases of cutaneous melanoma with sentinel lymph node (LN) (SLN) metastases reduced frequency of performance of completing lymphadenectomy. However, until now, domestic and foreign clinical recommendations indicate possibility of using this procedure in patients with an unfavorable prognosis while criteria are not provided for assessing the risk of non-sentinel LN (NSLN) damage and the need to perform lymphadenectomy.Aim. To identify predictors of high risk of metastasis in NSLN in patients with cutaneous melanoma with subclinical metastases in SLN.Materials and methods. The study included 92 patients with clinically localized cutaneous melanoma (cT1–4N0M0), who showed subclinical lesions as a result of SLN biopsy, and therefore underwent a final lymphadenectomy.Results. In the examined group, 26 (28.3 %) patients, along with SLN lesions, showed metastases in NSLN. Recognition of several active LNs during radionuclide mapping of SLNs is associated with a significantly higher risk of NSLN damage – in 42.3 % vs 15.2 % in the group with radiopharmaceutical activity only in SLNs (p = 0.018). Tumors thickness of >2 mm is also associated with a high frequency of NSLN metastasis (100 % of cases). No metastasis to other LNs was observed in tumor thickness of <2 mm. In ulcerated melanomas, the incidence of NSLN lesions was 92.3 % (p = 0.02). Only subcapsular localization of SLN metastases is associated with a relatively low incidence of NSLN metastasis (13.3 % of cases) as compared with parenchymal, mixed localization, and multifocal lesion (42.9 % of cases) (p = 0.002). For SLN metastases > 4 mm in size, a incidence of NSLN damage was higher than for metastases of <4 mm in size (43.3% vs 19.3%; p <0.05), as that for invasion of LN structures of > 2 mm in size versus invasion of <2 mm in size (44.4% vs 15.7 %; p = 0,003). The identified predictors of NSLN involvement in practice are often combined forming a pattern of predictors. The number of prognostic parameters in the pattern has a significant effect on the incidence of NSLN lesions (<0.001). In particular, the presence of 2 or less predictors is associated with low risk of metastasis in NSLN (0–12.5 % of cases), 3-5 predictors - with a relatively high risk (37.5–44.4 % of cases), 6 predictors – with a very high risk (80 % of cases).Conclusion. Recognition of predictors of metastasis in NSLN and their number allows us to decide on the need to perform final lymphadenectomy in patients with cutaneous melanoma with subclinical metastases in SLN. Conducting the final lymphadenectomy in patients with a high risk of multiple lesions of regional LNs will provide better locoregional control over stage III cutaneous melanoma and will create optimal conditions for adjuvant drug therapy.
