Sustainable Business as a Force for Good in the Context of Climate Change: An Econometric Modelling Approach
Authors: Shmelev Stanislav Edward , Gilardi Elisa
Published: February 2025

Global CO2 concentrations continue to rise despite significant efforts to decarbonize and reduce greenhouse gas emissions. This paper examines the role of sustainable business in reducing and limiting global CO2 concentrations based on daily CO2 data from the Mauna Loa Observatory. Based on the theory of the carbon cycle, factors considered significant in determining global CO2 concentrations include emissions, affected by economic variables like the crude oil price and Dow Jones Sustainability Index but also absorption capacity, affected through biomass growth by astronomical variables such as total solar irradiance and cosmic rays. Considering pair-wise correlations between variables, particular attention is drawn to the fact that in the COVID-19 pandemic, when everyone was working from home, cars were not allowed on the roads, and planes were not flying, the correlation between the Dow Jones Sustainability Index and the global CO2 concentration was negative. The article tests the hypothesis that business can be a force for good and make a meaningful contribution towards reducing global CO2 concentrations. To this end, it offers an integrated model of global CO2 concentrations built according to the theory of the carbon cycle based on 2195 daily observations, including all the variables outlined above. The results confirm the hypothesis that business, expressed in the form of Dow Jones Sustainability Index, can play a role in reducing the global CO2 concentrations. A range of policy conclusions is drawn.

Authors: Aleca Ofelia Ema , Mihai Florin
Published: February 2025

The adoption of Industry 4.0 technologies supports the digital transformation of production processes, making them more efficient. This study examines how digital infrastructure, digital skills, and the use of cloud technologies influence labor productivity in European Union countries. Using econometric methods, including linear regressions and fixed-effects panel regressions, the analysis highlights the important role digital skills play in boosting productivity. It also identifies the adoption of cloud solutions as a catalyst for process efficiency, while widespread high-speed internet coverage supports the connectivity of smart systems. However, variations in the development of digital infrastructure and workforce readiness across EU member states present challenges to overall labor productivity. The study concludes that strategic investments in automation and digital infrastructure, along with improving the workforce’s digital skills, are essential to making Industry 4.0 a key pillar of economic competitiveness. By examining how workforce digital skills and certain Industry 4.0 technologies affect labor productivity, this research adds valuable insights to the specialized literature.
Vitamin D Receptor and CYP450 Enzyme Dysregulation May Mediate Oral Cancer Responsiveness
Authors: Hunsaker Dustin , Moore James Landon , Howard Katherine M. , Kingsley Karl
Published: February 2025

Many health benefits are associated with Vitamin D (VitD), although deficiency is associated with poor health outcomes and the increased risk of cancer development. For example, many tissue-specific enzymes are involved in VitD metabolism, and mutations or deletions within Vitamin D receptor (VDR) genes are known to increase the cancer risk by altering their functions or bioavailability, although less is known about these phenomena in oral cancers. Using well-characterized, commercially available oral cell lines (OKF4, HGF-1, SCC4, SCC9, SCC15, SCC25, and CAL27), the mRNA expression of P450 cytochrome VitD metabolic enzymes and receptor genes by qPCR revealed differential results. One oral cancer line (SCC15) did not express either the Vitamin D receptor (VDR) or FOK1 polymorphism and was also least affected by VitD3 administration in growth assays. In contrast, most oral cancers were missing one or more hydrolase (CYP2R1 and CYP24A1) or hydrolate (CYP27A1 and CYP27B1) enzymes. SCC25 was missing both the hydrolate enzymes and was the most inhibited in the VitD3 growth assays, while SCC4 was missing both the hydroxylase enzymes and was the least inhibited by VitD2. These associations between mRNA expression (or lack thereof) and VitD3 and VitD2 responsiveness can be used to identify molecular targets, which may lead to effective screening tools for VitD-related, complementary and alternative therapies.
Solid State Transformers: A Review—Part I: Stages of Conversion and Topologies
Authors: Predescu Dragoș-Mihail , Roșu Ștefan-George
Published: February 2025

Solid State Transformers (SSTs) represent an emerging technology that seeks to improve upon traditional Low-Frequency Transformers (LFTs) with Medium-Frequency Transformers (MFTs) of reduced core size while incorporating modular converter structures as their input and output stages. In addition to magnetic circuit reduction, SSTs provide enhanced functionalities such as power factor correction, voltage regulation, and the capability to interface with various sources and loads. However, owing to the novelty of SSTs and the various proposed implementations, a general review would difficult to follow and might not be able to adequately analyze each aspect of SST structures. This complexity underscores the need for a new division of information and classification based on the number of conversion stages, which is the main contribution of this study. Converter functionalities are derived based on the number of stages. Utilizing these functionalities along with existing and proposed implementations, converter topologies are identified and then detailed in terms of their respective functionalities, advantages, disadvantages, and control schemes. The subsequent chapters provide a comparative analysis of the different topologies and present existing SST implementations. For this analysis, metrics such as the number of SST stages, power flow, voltage control, power quality, and component count are used. Based on the resulting analysis, single-stage SSTs are a promising solution that emphasize economy and high power density, while multi-stage SSTs are also a viable solution thanks to their ease of control and flexible design. This paper constitutes the first part of a two-part review. The second part will focus on the degrees of design freedom (such as multilevel structures/cells) and provide a generalized approach to modularity within SST systems.
Fuzzy Guiding of Roulette Selection in Evolutionary Algorithms
Authors: Pytel Krzysztof
Published: February 2025

This paper presents, discusses, and tests a novel method for guiding roulette selection in evolutionary algorithms. The new method uses fuzzy logic and incorporates information from both current and historical generations to predict the best scheme for the selection process. Fuzzy logic controls the probability of selecting individuals to the parent pool, based on historical data from the evolution process and the relationship between an individual’s fitness and the average fitness of the population. The new algorithm outperforms existing solutions by ensuring a proper balance between exploring new regions of the search space and exploiting previously found ones. The proposed system enhances the performance, efficiency, and robustness of evolutionary algorithms while reducing the risk of stagnation in suboptimal solutions. Results of experiments demonstrate that the newly developed algorithm is more efficient and resistant to premature convergence than standard evolutionary algorithms. Tests on both function optimization problems and real-world connected facility localization problems confirm the robustness of the newly developed algorithm. The algorithm can be an effective tool in solving a wide range of optimization problems, for example, optimization of computer network infrastructure.

Published: February 2025

When chips perform numerous computational tasks or process complex instructions, they generate substantial heat, potentially affecting their long-term reliability and performance. Thus, accurate and effective temperature measurement and management are crucial to ensuring chip performance and lifespan. This paper presents a multi-channel temperature measurement system based on a diode temperature-sensitive array thermal test chip (TTC). The thermal test chip accurately emulates the heat power and thermal distribution of the target chip, providing signal output through row and column address selection. The multi-channel temperature measurement system centers around a microcontroller and includes voltage signal acquisition circuits and host computer software. It enables temperature acquisition, storage, and real-time monitoring of 16 channels in a 4 × 4 array thermal test chip. During experiments, the system uses a constant current source to drive temperature-sensitive diodes, collects diode output voltage through multiplexers and high-precision amplification circuits, and converts analog signals to digital signals via a high-speed ADC. Data transmission occurs via the USB 2.0 protocol, with the host computer software handling data processing and real-time display. The test results indicate that the system accurately monitors chip temperature changes in both steady-state and transient thermal response tests, closely matching measurements from a semiconductor device analyzer, with an error of about 0.67%. Therefore, this multi-channel temperature measurement system demonstrates excellent accuracy and real-time monitoring capability, providing an effective solution for the thermal design and evaluation of high power density integrated circuits.
Fate of Mixmaster Chaos in a Deformed Algebra Framework
Authors: Barca Gabriele , Giovannetti Eleonora
Published: February 2025

We analyze the anisotropic Bianchi models, and in particular the Bianchi Type IX known as the Mixmaster universe, where the Misner anisotropic variables obey Deformed Commutation Relations inspired by Quantum Gravity theories. We consider three different deformations, two of which have been able to remove the initial singularity similarly to Loop Quantum Cosmology when implemented in the single-volume variable. Here, the two-dimensional algebras naturally implement a form of Non-Commutativity between the space variables that affects the dynamics of the anisotropies. In particular, we implement the modifications in their classical limit, where the Deformed Commutators become Deformed Poisson Brackets. We derive the modified Belinskii–Khalatnikov–Lifshitz map in all the three cases, and we study the fate of the chaotic behavior that the model classically presents. Depending on the sign of the deformation, the dynamics will either settle into oscillations between two almost-constant angles, or stop reflecting after a finite number of iterations and reach the singularity as one last simple Kasner solution. In either case, chaos is removed.

Published: February 2025

This study examined spatial–temporal variations in air pollutant levels across four provinces on Sumatra Island, Indonesia, utilizing data from the Sentinel-5P satellite equipped with TROPOMI and MODIS aboard NASA’s Terra and Aqua satellites from 2019 to 2021. Sentinel-5P data, with a spatial resolution of 3.5 × 5.5 km2 and near-daily temporal coverage, were used to analyze the nitrogen dioxide (NO2), carbon monoxide (CO), and Aerosol Optical Depth (AOD) in North Sumatra, West Sumatra, Jambi, and Riau—regions selected for their distinct industrial, agricultural, and urban characteristics. The purpose of this study was to investigate seasonal trends, regional differences, and the impact of the COVID-19 pandemic on air pollution, aiming to provide insights for improved air quality management and policy development. The satellite data were validated using zonal statistics to ensure consistency and reliability. The findings revealed significant seasonal fluctuations in pollution, with elevated levels during the dry season, primarily due to land clearing and forest fires. Urban and industrial areas such as Medan, Pekanbaru, Jambi, and Padang consistently exhibited high levels of NO2, primarily due to vehicular and industrial emissions. The regions affected by biomass burning and agriculture, particularly Jambi and Riau, displayed notably higher CO and AOD levels during the dry season. The COVID-19 pandemic provided a unique opportunity to observe potential improvements in air quality, with significant reductions in NO2, CO, and AOD levels during the 2020 lockdowns. The NO2 levels in urban centers decreased by over 20%, while the reductions in CO and AOD reached up to 29% and 64%, respectively, reflecting diminished human activities and biomass burning. This study underscores the need for enhanced air quality monitoring and targeted management strategies in Sumatra, Indonesia. Future research should aim to improve the resolution and validation of data with ground-based measurements and broaden the number of pollutants studied to better understand air quality dynamics and support effective policy development.

Published: February 2025

A nuclear export signal (NES) is a cluster of hydrophobic amino acids that can maintain the dynamic shuttling of target proteins between the nucleus and cytoplasm. Bioinformatics analysis showed that the hydrophobic region of 92PLLLHKFLLA in Bm65 is very likely to be an NES and may be involved in the production of infectious virions. In this study, we generated several mutations in 92PLLLHKFLLA of Bm65, which were further used to generate recombinant viruses to study their roles in viral propagation. Subcellular analysis revealed that the 92PLLLHKFLLA sequence was an NES involved in the dynamic transport of Bm65. Mutations in the hydrophobic region could block the formation and accumulation of Bm65 aggregates, resulting in a uniform distribution of Bm65 in BmN cells. The ribosomal protein L13 (RPL13) of silkworms was previously reported to interact with Bm65. Here, intracellular co-localization analysis showed that the interaction between Bm65 and RPL13 was regulated by the 92PLLLHKFLLA of Bm65. In summary, the interaction between Bm65 and RPL13 is essential for the production and accumulation of Bm65 aggregates and may play an important role in the regulation of viral propagation.

Introduction: Hepatitis D virus (HDV) infection remains a significant global health challenge due to its severity and high risk of progression to cirrhosis and hepatocellular carcinoma (HCC). Bulevirtide, a novel HDV entry inhibitor, has shown promise in managing chronic hepatitis D by blocking viral entry into hepatocytes. This study evaluated the efficacy and safety of bulevirtide in reducing HDV RNA levels and improving liver function in a real-life cohort of Italian patients with HDV infection. Methods: This multicenter prospective trial enrolled 108 consecutive patients with chronic HDV infection, from June 2023 to June 2024, who received 2 mg/day of bulevirtide in combination with a nucleoside/nucleotide analogue for hepatitis B virus (HBV) infection. Patients with any stage of liver fibrosis or compensated cirrhosis were included. Data collected included demographic and clinical characteristics, liver function tests, HDV RNA levels, and adverse events at baseline and 6 months. Results: The virological response was achieved in 54.6% of patients (n = 59), with 36 demonstrating undetectable HDV RNA levels. Among responders, ALT levels decreased significantly from 67.0 U/mL [IQR 44.0–116.3] to 31.5 U/mL [IQR 24.0–36.5, p = 0.001], and AST levels from 66.0 U/mL [IQR 46.5–91.0] to 32.5 U/mL [IQR 28.0–38.0, p = 0.021]. Median HDV RNA dropped from 29,800 IU/mL [IQR 3100–375,000] to 0 IU/mL [IQR 0–291, p < 0.001]. No significant predictors of response emerged. Mild adverse events, including pruritus (5.6%) and injection-site reactions (1.9%) and flu-like syndrome (0.9) were reported, with no treatment discontinuation. Conclusions: Bulevirtide effectively reduces HDV RNA levels and improves liver function with a favorable safety profile, offering a promising therapeutic option for chronic hepatitis D. Further large-scale studies are needed to confirm these findings and explore long-term outcomes.

Background/Objectives: Immunization with the hepatitis B vaccine is the most effective means of preventing acute HBV infection. However, whether the primary vaccination of infants confers lifelong immunity remains controversial. Therefore, the ongoing surveillance of vaccine recipients is required. Methods: A longitudinal study was carried out based on LongAn county, one of the five clinical trial centers for hepatitis B immunization in China in the 1980s. Serum samples were collected and tested for HBV serological markers and DNA. Results: A total of 637 subjects born in 1987–1993 were recruited, including 503 males and 134 females. The total prevalence of HBsAg was 3.9%. The prevalence in females (8.2%) was significantly higher than that in males (2.8%) (p = 0.004). The prevalence of anti-HBc in females (52.2%) was also significantly higher than that in males (41.2%) (p = 0.021). The prevalence of anti-HBs was 42.7% and did not differ significantly between males (41.7%) and females (46.3%) (p = 0.347). Compared to data from surveillance over the last ten years, the positivity rate of HBsAg did not increase. The positivity rate of anti-HBs decreased significantly (p = 0.049) while that of anti-HBc increased significantly (p = 0.001). The prevalence of occult HBV infection (OBI) in 2024 (6.0%) was significantly higher than that in 2017 (1.6%) (p = 0.045). Subjects diagnosed with OBI in 2017 maintained occult infection in 2024. Conclusions: Neonatal HBV vaccination maintained effective protection for at least 37 years. However, the prevalence of OBI increases with age in those vaccinated at birth, raising a new issue of how to prevent and control OBI in the post-universal infant vaccination era.
A Review of Biological and Sustainable Management Approaches for Alphitobius diaperinus, a Major Pest in Poultry Facilities
Authors: Tufan-Cetin Ozge , Cetin Huseyin
Published: February 2025

The lesser mealworm (Alphitobius diaperinus) is a significant pest in poultry facilities, transmitting pathogens such as Salmonella and causing structural damage in poultry operations. Challenges such as insecticide resistance and environmental concerns associated with the widespread use of traditional insecticides underscore the need for sustainable alternatives. This review examines biological and sustainable management strategies for managing the lesser mealworm, including entomopathogenic fungi, bacteria, nematodes, plant essential oils-extracts, pheromones, and diatomaceous earth. These eco-friendly approaches highlight fungi and nematodes for their effectiveness in larval control and essential oils for their insecticidal and repellent properties. The application of pheromones and diatomaceous earth further complements other methods within integrated pest management (IPM) systems. Integrating these biological tools into IPM offers a sustainable and effective solution for reducing A. diaperinus populations, addressing both health and environmental concerns.

Authors: Prado Masiel Melissa Pereira , Ortiz-Guerrero Cesar Enrique
Published: February 2025

This article examines dams from a relational perspective, understanding them as hydrosocial infrastructures resulting from interactions between actors, their mental models, institutions, and water flows. Through a literature review in the fields of science and technology as well as socioecological studies, we identified six attributes and five drawbacks of dams from a relational perspective that are not usually fully considered. Additionally, we collated these drawbacks and attributes for four dams in Colombia. The article contributes theory to approaching energy infrastructures, such as dams, from the hydrosocial, socioecological, and sociotechnical literature. The article highlights the importance of a new view to planning and government of the territory, as well as water administration and energy transition toward more just socioecological relations.

Published: February 2025

In the context of continued global population growth and various environmental challenges, the coordinated protection of water resources, energy, and food security has become increasingly important. This study focuses on the uneven distribution of water resources, food, and energy in China, examining the coupling coordination relationship within the Water–Energy–Food nexus (WEF) system from 2006 to 2020 and conducting a quantitative assessment of its spatial equilibrium state. The results indicate the following: (1) The WEF system coupling degree across China’s provinces (municipalities and autonomous regions) is above 0.75, suggesting a close interdependence and synergy between water resources, energy, and the food system. Most regions maintain a dynamically balanced coupling coordination state over time, providing theoretical feasibility for optimizing the allocation of cross-regional and cross-system resources. (2) Natural endowments and human activities have a decisive impact on spatial equilibrium differences in the water resources system. The layout of energy production is closely related to equilibrium, and overly concentrated production areas can disrupt spatial equilibrium. Future energy planning must consider the synergistic relationship between production and consumption areas. The proportion of grain output is not positively or negatively correlated with the spatial equilibrium coefficient; if regions with concentrated or sparse grain production cannot coordinate their development, the overall spatial equilibrium level will decline. (3) The spatial equilibrium of the WEF system is superior to that of any single subsystem. Inherent deficiencies in natural endowments can be gradually adapted and maintained through policy adjustments, resource coordination, and regional collaboration, allowing the system to maintain a dynamic balance.
Optimising Ventilation Strategies for Improved Driving Range and Comfort in Electric Vehicles
Authors: Lesage Matisse , Chalet David , Migaud Jérôme
Published: February 2025

A car cabin’s small volume makes it vulnerable to discomfort if temperature, humidity, and carbon dioxide levels are poorly regulated. In electric vehicles, the HVAC system draws energy from the car battery, reducing the driving range by several dozen kilometres under extreme conditions. A 1D simulation model calibrated for the Renault ZOE was used to evaluate the effects of ventilation parameters on thermal comfort, humidity, and power consumption. The results highlighted the interdependence of factors such as the recirculation ratio and blower flow rate, showing that energy-efficient settings depend on ambient conditions and other factors (such as occupancy, vehicle speed, infiltration). Adjustments can reduce heat pump energy use, but no single setting optimally balances power consumption and thermal comfort across all scenarios. The opti-CO2 mode is proposed as a trade-off, offering energy savings while maintaining safety and comfort. This mode quickly achieves the cabin temperature target, limits carbon dioxide concentration at a safe level (1100 ppm), minimises fogging risks, and reduces heat pump power consumption. Compared to fresh air mode, the opti-CO2 mode extends the driving range by 9 km in cold conditions and 26 km in hot conditions, highlighting its potential for improving energy efficiency and occupant comfort in electric vehicles.

Published: February 2025

Salmonellosis in humans is a public health threat and cattle are important reservoirs for the pathogen. Cattle products such as ground beef have been linked to human salmonellosis outbreaks, and some disease investigations have been traced back to infected animal herds on farms and animal markets as the origin of infection. It is now common to isolate Salmonella from many cattle operations as the pathogen once introduced onto a farm can establish an undesirable endemic condition among herds. It is, therefore, essential to adopt measures to mitigate or prevent the introduction and spread of zoonotic disease agents like Salmonella in animal populations. With this background, the potential sources and risks of Salmonella infection in cattle, the control of already established infection, and other preventative measures are discussed in this article. We conclude that a holistic approach involving all stakeholders in cattle production is needed to safeguard public health, eventually forestalling human salmonellosis from cattle sources. In achieving this, it will be essential to consider the farm as a critical control point in preventing the introduction of Salmonella into the food chain.

Authors: Villanueva Delgado Denisse
Published: February 2025

La depresión puede disminuir el compromiso de los pacientes con su tratamiento, lo que provoca una menor adherencia. Por ello, el objetivo de la investigación fue determinar la relación entre la depresión y la adherencia al tratamiento en pacientes con tuberculosis pulmonar en Centros de Salud de La Victoria, Lima, Perú. Se adoptó un enfoque cuantitativo, descriptivo, correlacional, transaccional y no experimental. La muestra se conformó por 127 pacientes. Se aplicaron dos cuestionarios, el BDI-II y el MMAS-8. Los resultados mostraron que el 63 % no presentó síntomas de depresión y el 77,2 % se adhirió al tratamiento. Se encontró una relación negativa débil entre ambas variables (r = -0,163 y p = 0,067), por lo que no puede afirmarse con certeza que a niveles más altos de depresión existe menor adherencia al tratamiento. Se concluye, que es importante desarrollar estrategias que contemplen el tratamiento médico con el apoyo psicológico.

This study examines the influence of sound culture on the semantic classification of oboe timbre, comparing Brazilian and Québécois musicians. The research investigates how physical reed characteristics and cultural contexts shape timbral perceptions. An online perceptual test was conducted using seven oboe recordings, evaluated through the Verbal Attribute Magnitude Estimation (VAME) method. Participants rated the timbre along six semantic scales: strident, bright, clear, muffled, round, and dark. Statistical analysis revealed no significant differences between Brazilian and Québécois classifications, except for the adjective "dull" The findings indicate overall similarities in timbral descriptions across cultures, though certain stimuli exhibited notable perceptual differences. Further research with larger, more diverse samples is recommended.
Corporalidade e composição musical eletroacústica: Deep Listening e cognição incorporada aplicados ao projeto LuISe
Authors: Lamha Anna
Published: February 2025

O projeto LuISe (Luva de Integração Sensorial), idealizado em 2020 e desenvolvido a partir de 2022, tem a proposta de articular os conceitos contidos na prática do Deep Listening de Pauline Oliveros e no conceito de cognição incorporada trazida em Guilherme Bertissolo, trazendo a filosofia da língua Tupi-Guarani como inspiração para tal articulação. Ambos os conceitos convergem no que se diz respeito à intrinsecabilidade do aspecto corporal na música. Também podem convergir-se, teorizo, no que se diz respeito ao fim da barreira dicotômica entre o pensamento e o corpo, mostrando-nos uma possibilidade de experienciar a nós mesmos, através da prática musical, como seres unificados — ainda que múltiplos —, tratando do mais íntimo elemento com o qual podemos nos relacionar no mundo físico: nosso corpo.

O transplante hepático é a única terapia curativa para pacientes com doença hepática terminal. No entanto, a escassez de órgãos continua sendo um grande obstáculo, resultando em longas listas de espera e alta mortalidade. Nesse contexto, a utilização de doadores em parada cardíaca controlada (DCC) tem sido adotada como uma alternativa viável para aumentar a oferta de enxertos. Apesar do potencial benefício, essa estratégia apresenta desafios específicos, como o tempo prolongado de isquemia quente, maior incidência de complicações biliares e necessidade de protocolos rigorosos para minimizar danos ao enxerto. Estudos internacionais demonstram que, quando corretamente manejados, os enxertos hepáticos de DCC apresentam sobrevida comparável aos de doadores em morte encefálica. Além das questões técnicas, a implementação desse modelo levanta dilemas éticos e exige consentimento familiar explícito, bem como infraestrutura especializada para otimizar os desfechos. O presente estudo tem como objetivo analisar os desafios e os resultados a longo prazo do transplante hepático com doadores em parada cardíaca controlada, avaliando sua viabilidade em diferentes contextos clínicos e socioeconômicos.

Published: February 2025

O presente estudo possui como objetivo evidenciar a literatura sobre à prática de atos infracionais em adolescentes, explorando os fatores psicossociais, neuropsicológicos e contextuais. Realizou-se uma revisão de escopo, utilizando diretrizes do PRISMA-SCR e metodologias do Instituto Joanna Briggs (JBI). Foram incluídos estudos experimentais, observacionais e qualitativos, além de relatórios governamentais e revisões sistemáticas, das bases PubMed/MEDLINE e SciELO. Os resultados destacam que processo de maturação cerebral, caracterizado por mudança no desenvolvimento de regiões-chave, torna a adolescência um período crítico, marcada por uma maior suscetibilidade a influências externas. Adolescentes em conflito com a lei, em sua maioria, vivenciam trajetórias psicossociais influenciadas por ambientes desfavoráveis ao desenvolvimento, os quais contribuem para o aumento do risco de transtornos mentais e comportamentais, reforçando vulnerabilidades e dificultando processos de ressocialização. Dados do Sistema Nacional de Atendimento Socioeducativo (SINASE, 2023) e estudos governamentais complementares revelam avanços, como a redução do número de adolescentes em privação de liberdade no Brasil, mas também evidenciam desigualdades no acesso à educação e à saúde mental. Observou-se que abordagens internacionais focadas na reabilitação e prevenção têm maior eficácia na redução da reincidência. Este trabalho sugere que a integração de políticas públicas, assistência em saúde mental e abordagens psicossociais pode contribuir para um sistema socioeducativo mais eficaz, com o intuito de romper os ciclos de vulnerabilidade e promover a ressocialização. As lacunas na implementação de políticas e as desigualdades estruturais permanecem como desafios.

Este estudo busca analisar os dados epidemiológicos da Tuberculose (TB) no estado do Ceará entre 2010 a 2023. Foi realizado um estudo ecológico com base nos dados notificados no Sistema de Informações de Agravos de Notificação (SINAN). Foram analisados ​​os registros de casos de TB, considerando sexo, faixa etária, escolaridade, hábitos de vida, tipos de TB e os desfechos clínicos. Foram registrados 47.588 novos casos de TB e 3.782 casos de recidivas, a maior parte no sexo masculino, com 33.706 casos (65,6%). A maior concentração ocorreu entre indivíduos de 25 a 44 anos de idade, com destaque para o grupo de 25 a 34 anos, com 10.840 casos (21,1%), acompanhados pelo grupo de 35 a 44 anos, com 9.396 casos (18,3%). A forma pulmonar foi predominante, com 43.910 casos (85,5%). 67,7% dos casos evoluíram para a cura, enquanto 2,7% resultaram em óbito, o que corresponde a uma taxa de letalidade foi de 2,637% nos novos casos e de 3,358% nos casos de recidiva. Entre os óbitos, 87,5% foram causados ​​pela forma pulmonar da doença, que apresentou uma taxa de letalidade nos novos casos de 2,269% e nos casos de recidivas 3,120%. Os dados analisados ​​indicam que a TB tem causado impacto no estado do Ceará ao longo dos anos, com um aumento específico no número de casos. A TB pulmonar destacou-se não apenas pelo maior número de notificações, mas também pela sua maior letalidade, reforçando a importância de estratégias efetivas para o diagnóstico precoce, tratamento e controle da doença.

O contexto pós-pandêmico, marcado por eventos adversos no âmbito educacional, impactou negativamente a vida universitária, intensificando os desafios já enfrentados, como alta prevalência de transtornos mentais, alterações no calendário das universidades, sobrecarga de atividades e dificuldade de reintegração social. Essa pesquisa, realizada com estudantes de medicina da Universidade Federal de Ouro Preto, em Minas Gerais, Brasil, utilizou uma abordagem quanti-qualitativa para avaliar o sofrimento mental dos estudantes na pós pandemia. Os participantes estavam na faixa etária de 19 a 28 anos e eram estudantes do 2º ao 12º período do curso. Os resultados indicam que o retorno presencial pós-crise gerou adaptações e desafios psicossociais, aumentando os níveis de estresse, ansiedade e depressão. Identificou-se a percepção coletiva da vida universitária no curso de medicina como estressante, com elevadas exigências e competitividade, o que destacou a importância das relações sociais na preservação da saúde mental e a necessidade de estratégias de acolhimento e psicoeducação na universidade.
