Authors: Chen Ju-Luo , Wang Rui , Ma Pei-Qi , Wang You-Meng , Tang Qi-Qiang
Published: November 2024

BACKGROUND

Cerebral small vessel disease (CSVD) is a prevalent cerebrovascular disease in clinical practice that is often associated with macrovascular disease. A clear understanding of the underlying causes of CSVD remains elusive.

AIM

To explore the association between intercellular adhesion molecule-1 (ICAM-1) and blood-brain barrier (BBB) penetration in CSVD.

METHODS

This study included patients admitted to Fuyang People’s Hospital and Fuyang Community (Anhui, China) between December 2021 and March 2022. The study population comprised 142 patients, including 80 in the CSVD group and 62 in the control group. Depression was present in 53 out of 80 patients with CSVD. Multisequence magnetic resonance imaging (MRI) and dynamic contrast-enhanced MRI were applied in patients to determine the brain volume, cortical thickness, and cortical area of each brain region. Moreover, neuropsychological tests including the Hamilton depression scale, mini-mental state examination, and Montreal cognitive assessment basic scores were performed.

RESULTS

The multivariable analysis showed that age [P = 0.011; odds ratio (OR) = 0.930, 95% confidence interval (CI): 0.880-0.983] and ICAM-1 levels (P = 0.023; OR = 1.007, 95%CI: 1.001-1.013) were associated with CSVD. Two regions of interest (ROIs; ROI3 and ROI4) in the white matter showed significant (both P < 0.001; 95%CI: 0.419-0.837 and 0.366-0.878) differences between the two groups, whereas only ROI1 in the gray matter showed significant difference (P = 0.046; 95%CI: 0.007-0.680) between the two groups. ICAM-1 was significantly correlated (all P < 0.05) with cortical thickness in multiple brain regions in the CSVD group.

CONCLUSION

This study revealed that ICAM-1 levels were independently associated with CSVD. ICAM-1 may be associated with cortical thickness in the brain, predominantly in the white matter, and a significant increase in BBB permeability, proposing the involvement of ICAM-1 in BBB destruction.

Authors: Yu Teng-Fei , Liu Li , Shang Lu-Ning , Xu Fang-Fang , Chen Zhi-Min , Qian Li-Ju
Published: November 2024

BACKGROUND

Depression is a prevalent psychological issue in adolescents that is significantly related to negative life events (NLEs) and dysfunctional attitudes. High levels of social support can significantly buffer NLEs’ effect on depression. Currently, there is limited research on how social support moderates the relationship between NLEs, dysfunctional attitudes, and depression in adolescents in China. It is imperative to investigate this moderating effect to mitigate dysfunctional attitudes in adolescent undergoing depressive mood, ultimately enhancing their overall mental health.

AIM

To investigate the relationship and underlying mechanisms between specific dysfunctional attitudes, social support, and depression among Chinese adolescents.

METHODS

This is a cross-sectional study which selected five middle schools in Shandong Province for investigation in March 2022. Participants included 795 adolescents (49.87% male, mage = 15.15, SD = 1.84, age range = 11-18 years old). All participants completed the Dysfunctional Attitude Scale, Adolescent Life Event Scale, Beck Depression Inventory, and Social Support Rating Scale. A moderated mediation model was conducted to examine the relationship between specific dysfunctional attitudes, social support, and depression.

RESULTS

Results indicated that NLEs affected depression through the mediating role of specific dysfunctional attitudes (autonomy attitudes β = 0.21; perfectionism β = 0.25). Moreover, social support was found to moderate the mediating effect between NLEs, specific dysfunctional attitudes, and depressive symptoms (autonomy attitudes b2 = -0.08; perfectionism b2 = -0.09).

CONCLUSION

Dysfunctional attitudes mediated and social support moderated the relationship between NLEs and depression. Social support can buffer depression symptoms among adolescents with autonomy attitudes and perfectionism.

Published: November 2024

BACKGROUND

Research has found that the amygdala plays a significant role in underlying pathology of major depressive disorder (MDD). However, few studies have explored machine learning-assisted diagnostic biomarkers based on amygdala functional connectivity (FC).

AIM

To investigate the analysis of neuroimaging biomarkers as a streamlined approach for the diagnosis of MDD in adolescents.

METHODS

Forty-four adolescents diagnosed with MDD and 43 healthy controls were enrolled in the study. Using resting-state functional magnetic resonance imaging, the FC was compared between the adolescents with MDD and the healthy controls, with the bilateral amygdala serving as the seed point, followed by statistical analysis of the results. The support vector machine (SVM) method was then applied to classify functional connections in various brain regions and to evaluate the neurophysiological characteristics associated with MDD.

RESULTS

Compared to the controls and using the bilateral amygdala as the region of interest, patients with MDD showed significantly lower FC values in the left inferior temporal gyrus, bilateral calcarine, right lingual gyrus, and left superior occipital gyrus. However, there was an increase in the FC value in Vermis-10. The SVM analysis revealed that the reduction in the FC value in the right lingual gyrus could effectively differentiate patients with MDD from healthy controls, achieving a diagnostic accuracy of 83.91%, sensitivity of 79.55%, specificity of 88.37%, and an area under the curve of 67.65%.

CONCLUSION

The results showed that an abnormal FC value in the right lingual gyrus was effective as a neuroimaging biomarker to distinguish patients with MDD from healthy controls.

Published: November 2024

BACKGROUND

Diagnosing and treating abdominal infection in children remains a challenge. Nucleic acid detection, as a rapid and accurate diagnosis tool, has great significance in this field.

AIM

To investigate the diagnosis and treatment of abdominal infection by nucleic acid detection and its possible correlation with psychological stress in children.

METHODS

A total of 50 pediatric patients diagnosed with abdominal infections between September 2020 and July 2021 were included in this study. Intra-abdominal pus samples were collected for pathogen culture, drug susceptibility testing, and broad-spectrum bacterial nucleic acid testing. Psychological stress, anxiety, depression, and coping styles were assessed using the coping with a disease (CODI) scale.

RESULTS

Based on susceptibility testing, a regimen of cefazoxime, piperacillin/tazobactam, and metronidazole or ornidazole achieved 100% effectiveness in treating appendicitis. Psychological assessments revealed a positive correlation between pressure level and both anxiety (r = 0.324, P = 0.001) and depressive disorders (r = 0.325, P < 0.001). Acceptance and distancing as coping strategies were negatively correlated with anxiety and depression, while negative emotional responses were strongly associated with increased anxiety (r = 0.574, P < 0.001) and depression (r = 0.511, P = 0.001). Coping strategies such as illusion and escape showed no significant correlation with emotional outcomes.

CONCLUSION

Nucleic acid testing helps in the diagnosis of abdominal infections in children, and also focuses on children's mental health.

Enhancing adolescent mental health through cognitive and social support: Insights from study on depression in Chinese adolescents
Authors: Okpete Uchenna E , Byeon Haewon
Published: November 2024

Adolescent depression is a growing global health concern, affecting 14% of adolescents and leading to severe consequences such as academic failure, substance abuse, and suicidal ideation. The study by Yu et al , investigates the cognitive and social factors influencing depression in 795 Chinese adolescents. Findings reveal that negative life events (NLEs) and dysfunctional attitudes are strongly associated with depressive symptoms, while social support moderates the impact of NLEs but not dysfunctional attitudes. The study highlights the need for cognitive-behavioural interventions targeting perfectionism and autonomy, and the importance of strengthening social support systems in schools and communities. Culturally sensitive, holistic approaches to adolescent mental health are crucial for addressing both the internal vulnerabilities and external pressures contributing to depression. Further research is needed to explore the roles of peer and parental support and the long-term effects of these factors across diverse cultural contexts.

The paper explores the optimal placement of the chemical blocking agent (water shut-off material) in a high-permeability watered sublayer under uncertainty of its geometry in the inter-well area. The simulation of the water flooding process at different sublayer positions and variations of blocking agent placement was performed using a high-speed computing two-dimensional model of stream tube. The decision of the optimal placement of the water shut-off agent was made using probabilistic processing of the results without using a large amount of resource-intensive numerical simulation. The relationship between the optimal water shut-off scenario and the sublayer geometry is demonstrated. The relationship between the parameters of the sublayer geometry distribution function and the probabilistic behavior of the generalized efficiency has been established. Simulations are performed for various mobility ratios: in cases with equal viscosity liquids and typical ones for reservoirs in the Volga region and Western Siberia. Keywords: petroleum reservoir; high-permeability layer; geological uncertainty; early water breakthrough; water shut-off; stochastic modeling; two-phase flow; model of stream tube.

The article discusses the hydraulic features of the «well, collection and transport» system and the issue of selecting the diameter of subsea pipelines at given technological limitations, flow rate and pressure at the beginning of export pipeline. Taking into account the interactions of the phases, various options for the hydraulic calculation of multiphase gas-condensate pipelines are analyzed. Provided, that economic considerations for the development of gas condensate resources require a significant revision of some traditional onshore positions in the design of offshore subsea pipelines. Analysis of the functioning of systems for collecting and transporting gas condensate mixtures is considered on the example of the development of the offshore field "Umid" in Azerbaijan, located at a distance of about 40 km from the coast. At the same time, the dynamics of the removal of accumulated fluid from the system of «well, collection and transport» showed a stable picture of preventing the hydrate formation. However, careful study shows that the cycle of accumulation and removal of the liquid phase has cyclic regime where the frequency is measured in days. Such a large frequency is mainly determined due to low condensate ratio as the natural gas. The calculation results showed that, in contrast to a single-phase flow, the distance of the gas-condensate fluid storage can’t be increased indefinitely with an increase in the diameter of the pipeline. Also, it is confirmed that the distance of the gas-condensate fluid storage depending on the diameter of the pipeline, taking into account the flow rate and pressure at the beginning, has a certain optimal value, which assures maximum stable operation. Keywords: gas-condensate resource; subsea pipelines; hydraulic features; multicomponent stream; gas-condensate storage; hydraulic resistance; flow regime.

Published: November 2024

Many production and injection wells do not operate at full capacity due to damage of the near-well zone of the formation. The most frequently used and at the same time effective means of combating this problem is acid treatment of wells. Unfortunately, there are certain geological and field conditions that significantly reduce the effectiveness of acid treatments. Among them we can list the complex composition of the reservoir, heterogeneity of the reservoir, high reservoir and bottomhole temperatures, low reservoir permeability and, conversely, the presence of highly permeable zones and fractures, high water cut in well production, asphalt, resin and paraffin deposits, formation of stable emulsions upon contact of an acid solution with reservoir fluids, insufficient well preparation for acid treatment, reservoir destruction, greater thickness of the treated interval in a vertical well and a large length of the horizontal section of the horizontal well, primary treatment or retreatment, etc. However, the «sour» result of such processing can be significantly «sweetened» using modern technologies of the oil and gas industry. This article examines these situations and suggests ways to solve these problems. Keywords: acid treatment; improved oil recovery (IOR); well stimulation; high reservoir temperature; low permeability; high water cut; formation of stable emulsions; treatment of thick reservoirs.

North Korea and Russia's dangerous partnership: The threat to global security from the Kim–Putin axis and how to respond
Authors: Howell Edward
Published: November 2024

Russia’s full-scale invasion of Ukraine in February 2022 has prompted a rapid escalation in cooperation between North Korea and Russia, to the point where in October 2024 North Korea was confirmed to have sent troops to assist Russian forces. Such actions show that the North Korea–Russia relationship has moved beyond the merely transactional to become a longer-term strategic and ideological partnership.

This still-developing partnership poses a threat to the international community, by increasing the potential for regional conflict and undermining the current international order. This research paper provides a wake-up call for the US and its partners in northeast Asia and beyond, warning them to take this emerging Kim–Putin axis seriously and recommending a set of actions to prepare for where this dangerous partnership might go next.

Neutral Real Interest Rate, Monetary Policy and Business Cycle: Using the Kalman Filter and a Counterfactual Structural Approach for a Large Emerging Market
Authors: Moreira Ricardo Ramalhete
Published: November 2024

Central banks monitor the evolution of economic aggregates in order to enhance the effectiveness of monetary policy, within the context of inflation targeting regimes. This paper assesses whether controlling or not the path of the neutral real interest rate alters business cycle responses to structural shocks in monetary policy. For this purpose, the study uses the Kalman filter to extract the latent variable of neutral interest rates, as well as a counterfactual exercise based on parsimonious SVAR models, both applied to Brazil. The evidence suggests that omitting the trajectory of the neutral real rate introduces biases in the estimated stochastic responses of economic activity to unanticipated changes in monetary policy. Quantitatively, this omission results in a loss of approximately 5% of the estimated marginal effects in the first 12 months, in addition to bringing forward the initial impacts by 6 months, and a loss of up to 70% in the estimated effects over a 24-month horizon. Such results were robust for the inclusion of the US long term real interest rate and the country risk perception.

Authors: KLAYKRUAYAT Benjamas , VUTHIGANOND Nattaya , CHITICHOTPANYA Pisutsaran
Published: November 2024

The utilization of agricultural wastes for textile dyeing has gained popularity due to their safe and environmentally friendly properties, as well as the resource sustainability. Natural dye extraction is usually achieved through solvent extraction, which is time-consuming, requires a lot of solvent, and degrades desired compounds at high temperatures. Thus, this study investigated ultrasound-assisted anthocyanin extraction from agricultural waste purple corn silk as natural functional colorants for hemp finishes, given the numerous health benefits associated with anthocyanin. In order to optimize the extraction processes and evaluate the synergistic impact of these conditions, response surface methodology was implemented. The optimum conditions were 1:15 material-liquid ratio, 47% ethanol concentration, 60°C, and 20 min, yielding 240.25 mg·L‒1 anthocyanin. The extracted anthocyanin was used for dyeing hemp fabrics and demonstrated satisfactory colorfastness, antibacterial action on both S.aureus and E.coli, with E.coli being more effective, and strong antioxidant (>80%). The dyed fabrics also exhibited their great UV shield (UPF value > 40+). Anthocyanin derived from purple corn silk could therefore be utilized as a natural functional color for medical and health products. Also, purple corn silk contains more anthocyanin than other natural sources, making it a promising natural anthocyanin resource in textile industry.

Published: November 2024

The study investigates volleyball performance indicators that distinguish winning and losing sets in men's and women's Asian competitions. It focuses on balanced sets, defined as those with a score difference of ≤ 5 points for men and ≤ 7 points for women, to avoid bias from lopsided sets. Data from the 2023 Men's and Women's AVC Challenge Cup was analysed. A six-level scale evaluated serve, reception, attack after reception and after defence, block and setting. Stepwise discriminant analysis identified the most significant performance indicators for winning a set in each gender. For men's teams, attack win percentage and serve win percentage were the most important factors. Teams with attack win percentages above 50% and serve win percentages above 7.5% exhibited a greater likelihood of winning. For women's teams, the analysis was not statistically significant, but attack win percentage after reception percentage showed the strongest influence. The study underscores the pivotal role of attack effectiveness in differentiating winning and losing sets, particularly for men's teams. Serve win percentage also plays a significant role for men. While the analysis for women's teams was inconclusive, attack success appears to be crucial. Future research could strengthen the findings for women's volleyball.

Published: November 2024

Background: Bicycle Motocross (BMX) has evolved to cater to different styles of riders, including Flatland, Street, Park, and Dirt. BMX culture is characterised by a unique framework of regulations, guidelines, and principles of which a subculture has a pronounced anti-establishment sentiment and embraced do-it-yourself (DIY) practices, contributing to its distinctive identity within the realm of sport. Formal organisations have emerged, leading to the legitimisation of BMX through events such as the Olympics.  To the author’s knowledge, this is the first attempt to identify and synthesise all academic publications on BMX and describe the emergence of this research. Methods: After adopting the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRIMSA) guidelines 940 studies were identified in the initial search and post screening 87 studies were included. Data was extracted to determine, among other things, the year of publication, methodology adopted, type of BMX and/or BMXers studied, discipline of the study, and focus of inquiry. No date limiter was applied to the search strategy. Results: We identified 87 BMX-related articles for analysis, published between 1982 to 2022. The majority of these studies were conducted within the disciplines of biomechanics and physiology/sports science with a primary focus on performance-enhancing techniques within BMX racing. Most studies have emerged from the UK, with both males and females as their gender sample, using quantitative methodology. Conclusions: This scoping review identified several trends in the history of BMX research. It also identified important gaps and possible avenues for future research to contribute to academic knowledge in this growing field.

Published: November 2024

Esta revisão tem por objetivo descrever as características do sulfato de condroitina (SC), suas fontes de obtenção, além de reunir estudos que demonstrem suas aplicações, na forma isolada ou associada, em produtos para a saúde humana.  O SC é um glicosaminoglicano distribuído nas células e matriz extracelular dos animais, promotor de resistência à tensão desempenhada em tecidos como cartilagens, tendões, ligamentos, válvulas cardíacas e paredes da aorta. As propriedades do SC despertam interesse em pesquisas clínicas, sobretudo as relacionadas ao tratamento da osteoartrite. O uso do SC tem sido amplamente avaliado e proposto como tratamento alternativo, ou complementar, ao uso de medicamentos anti-inflamatórios. As aplicações na área da saúde são amplas e envolvem principalmente pesquisas aplicadas à ortopedia, odontologia, oftalmologia, urologia, dermatologia e gastroenterologia. A utilização deve ser racional e pautada em evidências científicas, exigindo que pesquisas continuem a ser desenvolvidas a fim de evidenciar o potencial e confiáveis benefícios à saúde em detrimento ao uso empírico e alheio à ciência.

A leptospirose é uma doença infecciosa febril aguda causada pela bactéria Leptospira, transmitida principalmente pela urina dos ratos. No Brasil é endêmica e torna-se epidêmica em períodos chuvosos, em áreas urbanas de baixa renda, saneamento inadequado e alta infestação de roedores. Objetivo: Sintetizar as estratégias implementadas na prevenção e controle da leptospirose identificadas nas produções científicas.  Método: Revisão integrativa da literatura com síntese de estudos científicos publicados nos últimos cinco anos, utilizando bases de dados como LILACS, MEDLINE e BDENF. A questão norteadora foi: quais as estratégias de prevenção e controle da leptospirose implementadas nas Unidades Básicas de Saúde identificadas nas produções científicas? Incluiu-se estudos publicados nos últimos 5 anos. Seguiu-se as recomendações do Guia internacional PRISMA-ScR. Resultados: Foram abarcados 11 artigos. Quanto ao idioma, quatro estudos em Português e sete em Inglês, com abordagens metodológicas qualitativa, quantitativa e mista. Identificou-se duas categorias temáticas: potencialidades das estratégias de prevenção e controle da leptospirose e outra sobre as limitações das mesmas. Conclusão: o estudo sintetizou as estratégias de prevenção e controle da leptospirose, com destaque em suas potencialidades e suas limitações. A síntese evidenciou que a educação em saúde, a vigilância epidemiológica, o controle ambiental e de vetores, bem como o atendimento e diagnóstico precoce, são essenciais para a prevenção e controle eficaz da doença.

Trends in society show that people are depending on the use of plastic materials, due to the nature of plastic which is anti-rust, cheap, practical and lightweight. This trend causes the plastic waste in the environment out of the control. It takes a long time for plastic waste to be degraded by nature, and will cause environmental pollution if it is too late to deal with it. On the other hand, people's need for fuel increasingly, but the availability of the fuel on the nature are rared. Therefore, the effort in changging the plastic waste into fuel are important so that the problem of environmental pollution as well as the scarcity of fossil fuels can be overcome at once. Literature review is the method chosen in this study, where this method selects journals related to the conversion of plastic waste so that it can be used as fuel. The conclusion is the plastic waste can be converted into fuel through several methods, including cracking and pyrolysis, tools and materials needed can be obtained from the surrounding environment so that production costs can be reduced.

Umieszczenie człowieka w zakładzie karnym bądź areszcie śledczym oznacza utratę jednej z najbardziej cenionych i fundamentalnej wartości ludzkiej - wolności. Jest to działanie Państwa oparte na podstawie obowiązującego systemu regulacji prawnych, stanowiąc określoną reakcję na popełnione przestępstwo. Termin "jednostki penitencjarne" obejmuje zarówno zakłady karne, gdzie przebywają prawomocnie skazani, jak i areszty śledcze, gdzie zatrzymane są osoby podejrzane o popełnienie przestępstwa. Decyzję o umieszczeniu w areszcie śledczym podejmuje sąd na podstawie wniosku oskarżyciela publicznego, jeśli uzna go za uzasadniony. Bezpieczeństwo osadzonych jest gwarantowane przepisami prawa, takimi jak Kodeks Karny Wykonawczy, oraz innymi aktami prawnymi, przy czym administracja więzienna odgrywa istotną rolę w utrzymaniu bezpieczeństwa osadzonych w warunkach izolacji penitencjarnej.W niniejszym artykule przedstawiono problematykę odnoszącą się zarówno do podstaw prawnych i regulacji normatywnych funkcjonowania jednostek penitencjarnych jak również praktycznej realizacji działań funkcjonariusz Służby Więziennej i ich efektów w ramach obowiązujących procedur, w celu zapewnienia optymalnego poziomu bezpieczeństwa osadzonych.
