Authors: Hou Meili , Wang Jinxi , Liu Yurong , Bao Zewen , Panchal Balaji
Published: February 2025

In order to study the geochemical characteristics of coal in the Ningwu Coalfield of Shanxi Province and the coal-forming environments reflected by it, a detailed geochemical study was carried out on the No. 5 coal of the Zhaokai Mine. The results show that the content of major-element oxides SiO2 and Al2O3 is high. The trace elements Ni, Nb, Mo, Cd, Sn, Hf, Ta, W, Th, and U are slightly enriched, while the elements Li and Zr are enriched, indicating an overall LREY enrichment type in the samples. Elemental parameters suggest that the sedimentary environment in the study area is continental sedimentary, and the whole environment is reductive. The macerals in the coal samples are mainly vitrinite, with an average vitrinite reflectance (Ro) of 0.744%. The distribution range of n-alkanes in the coal samples is from n-C14~n-C32, with the main peak carbons being n-C24 and n-C25, showing the post-single-peak type distribution pattern. The average odd–even predominance index (OEP) is 0.40, the average of the light and heavy hydrocarbons ratio (∑C21−/∑C22+) is 0.42, and the average of Pr/n-C17 and Ph/n-C18 are 1.08 and 0.23, respectively. The coal samples also contain various aromatic hydrocarbons, mainly from the naphthalene- and phenanthrene-series compounds. Biomarker parameters indicate that the parent material of the coal samples in the study area is mainly continental higher plants. The maturity is low, and the coal-forming environment is a reduction environment. This study of the No. 5 coal’s geochemical characteristics has laid a foundation for the efficient, green, and comprehensive exploitation of coal resources in this region, and has also provided an important basis for the sustainable development of coal resources.

Authors: Wan Xiaoman , Liu Ruipeng , Cheng Ailing
Published: February 2025

In this study, hydrochars loaded with iron species (Fe@HTC and Fe@HTC−T) were prepared by chemical co-precipitation and tubular furnace sintering treatment to develop efficient and sustainable catalysts for antibiotic wastewater treatment, addressing key challenges in sustainable environmental management. The characterization results indicated that iron species loaded on the hydrochars changed from Fe3O4 to FeO and then to metallic Fe with the pyrolysis temperature increased from 400 °C to 800 °C. The results of the characterization revealed a phase transition of iron species, confirming the temperature-dependent evolution of catalytic activity. The catalytic performance of the hydrochar composites was evaluated for tetracycline hydrochloride (TC–HCl) degradation via a Fenton-like process. Under optimal conditions (0.2 g/L TC–HCl, 0.1 g/L catalyst, 0.1 mM H2O2, pH = 6.86), Fe@HTC−T demonstrated excellent catalytic activity with a removal efficiency of 91.2%. Moreover, Fe@HTC−T exhibited superior stability and low iron leaching rates, attributed to the protective role of the hydrochar matrix. Mechanism research suggested that hydroxyl radicals (•OH) played a dominant role in the degradation process. This study demonstrates the potential of utilizing low-cost and renewable hydrochar materials derived from biomass waste to address industrial challenges in treating high-concentration antibiotic wastewater, offering a sustainable and cost-effective solution with broad applications in environmental remediation.
Total Momentum and Other Noether Charges for Particles Interacting in a Quantum Spacetime
Authors: Amelino-Camelia Giovanni , Fabiano Giuseppe , Frattulillo Domenico
Published: February 2025

There has been strong interest in the fate of relativistic symmetries in some quantum spacetimes, partly because of its possible relevance for high-precision experimental tests of relativistic properties. However, the main technical results obtained so far concern the description of suitably deformed relativistic symmetry transformation rules, whereas the properties of the associated Noether charges, which are crucial for the phenomenology, are still poorly understood. Here, we tackle this problem focusing on first-quantized particles described within a Hamiltonian framework and using as a toy model the so-called “spatial kappa-Minkowski noncommutative spacetime”, where all the relevant conceptual challenges are present but, as here shown, in technically manageable fashion. We derive the Noether charges, including the much-debated total momentum charges, and we reveal a strong link between the properties of these Noether charges and the structure of the laws of interaction among particles.
Systemic Approaches to Coopetition: Technology and Service Integration in Dynamic Ecosystems Among SMEs
Authors: da Silva Agostinho , Cardoso Antonio J. Marques
Published: February 2025

In the globalized, technologically advanced landscape, coopetition—simultaneously cooperating and competing—has become a key strategy for innovation and enhanced value creation. This research focuses on the impact of technology-driven coopetition networks in the Portuguese ornamental stone sector, using a framework based on Service-Dominant Logic (S-D Logic). It emphasizes the importance of resource integration, service exchange, and institutional arrangements in successful coopetition. Employing a two-phase experimental approach with selected small and medium enterprises (SMEs), this study assesses customer perceptions of product quality under traditional best practices versus those enabled by technology-driven coopetition networks. The results indicate a notable improvement in the customer-perceived quality and outcome consistency. The statistical analysis shows that these networks allow firms to better align with customer expectations, optimize resource allocation, and improve operational coordination. The findings highlight the strategic potential of coopetition networks, particularly when augmented by advanced technologies like IoT-based systems. These networks facilitate sustainable value co-creation and operational resilience by enabling firms to share expertise, distribute tasks, and synchronize efforts. This research contributes to the coopetition and S-D Logic literature by offering a practical framework for firms aiming to boost competitiveness and sustain growth in dynamic service ecosystems.

Published: February 2025

Flight line personnel are constantly exposed to noise and jet fuel while working on flight lines. Studies suggest that jet fuel in combination with noise affects hearing loss more than noise exposure alone. This study examined the combined effects of jet fuel and noise exposure on the hearing of flight line personnel stationed at Japan Air Self-Defense Force Air Bases (Hamamatsu, Matsushima, Hyakuri, Yokota, and Iruma) and US Air Force Air Bases (Kadena and Misawa) in Japan. Samples were collected from all participants, 97 flightline-exposed and 71 control volunteers, to measure their individual noise levels with a personal sound level meter and volatile organic chemicals (VOCs) with a chemical sampling pump during a single shift. Blood samples were collected post shift. Urine samples (entire void) were collected prior to the shift (morning first void) and post shift. VOCs were measured in air, blood, and urine. An audiometric test battery, consisting of immittance measurements, audiograms, distortion product otoacoustic emissions, and the auditory brain response, was conducted after the shift to examine the hearing of participants. Total VOCs in personal air samples were in the ppb range for each group. Tinnitus and temporary hearing loss were reported in audiological histories but were also present in some controls. Noise levels on the flight line were greater than the action level for requiring hearing protection and exceeded exposure limits, but all exposed subjects reported wearing hearing protection. Audiometric tests identified significant differences and trends between flight line and control personnel, indicating the potential for hearing disorders. In spite of very low levels of VOC exposure and wearing hearing protection for noise, there is still the potential for hearing issues in flight line personnel.
Urban Spatial Heat Resilience Indicator Based on Running Activity Z-Score
Authors: Zhou Li , Lai Yuan
Published: February 2025

The assessment of urban heat resilience has become crucial due to increasing extreme weather events. This study introduces the Running Activity Z-score (RAZ) index based on running activity trajectory data to evaluate heat resilience. Through a case study of an August 2022 heatwave in Beijing, we examined the index’s sensitivity to extreme heat and explored its spatial relationships with key built environment factors, including plot ratio, green coverage, population density, and blue space proximity. Our results reveal two key findings: (1) the RAZ index serves as an effective real-time, high-precision indicator of urban heatwave impacts, as evidenced by extremely low RAZ values consistently coinciding with heatwave periods, and (2) the RAZ index offers valuable insights for identifying potential low heat resilience areas and supporting planning decisions, as demonstrated by its significant correlations with built environment factors that align with previous studies while uncovering more detailed spatial relationships. Although RAZ effectively complements traditional measurement methods, its application requires careful consideration of external factors such as social dynamics and climate variability.

This study aimed to evaluate the effects of an ultra-diluted complex on the health status, growth performance, and blood parameters of dairy calves during the preweaning phase in a double-blind, placebo-controlled trial. During a 75-period trial, thirty-four Holstein newborn calves at the second day of life were completely randomized individually into two treatments: (1) control (CON), oral saline supplementation (5 mL/d); and (2) oral supplementation with 5 mL/d of a ultra-diluted complex (UD): Sulfur: 1060 + Viola tricolor: 1014 + Caladium seguinum: 1030 + Zincum oxydatum: 1030 + Phosphorus: 1060 + Cardus marianus: 1060 + Colibacillinum: 1030 + Podophyllum: 1030 + Vehicle: alcohol. Free access to water and a starter was ensured during the trial period. Feed intake and fecal and health scores were monitored daily. Calves were weighed and measured weekly. Blood samples were collected at enrollment on the first day and every 21 days until the 75th day, 2 h after morning milk feeding, and tested for hematology, blood urea nitrogen, aspartate aminotransferase, gamma-glutamyl transferase, total protein albumin, globulin, and creatinine. At 70 days of age, calves were disbudded following the standard management practices of the farm. The inflammatory profile, including Immunoglobulin A, Immunoglobulin G, ceruloplasmin, transferrin, albumin, and haptoglobin, was quantified in serum samples. The ultra-diluted complex was ineffective in reducing the incidence of diseases, starter feed intake, daily weight gain, and body measurements and inflammatory profile. Blood parameters were also not affected. Thus, the ultra-diluted complex was inefficient in reducing the incidence of diseases and did not affect the performance and metabolites of pre-weaned Holstein calves.

Authors: Wang Xinyu , Lai Jiaxin , Xu Fei , Liu Mingchun
Published: February 2025

In order to elucidate the active ingredients, potential targets, and mechanisms of action of peppermint in treating bovine mastitis, this study utilized network pharmacology analysis and molecular docking to conduct an exploratory, prospective investigation. Using the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database, all compounds and targets of peppermint were retrieved. After removing duplicates, a total of 133 compounds and 272 targets were obtained. Targets were then standardized to gene names using the UniProt database to construct a drug–component-target network. A total of 183 disease targets related to bovine mastitis were retrieved from the GeneCards database. We obtained 28 cross targets of peppermint targets and bovine mastitis targets, and constructed a protein–protein interaction (PPI) network using the STRING database. A visual network was built using Cytoscape 3.10.0 software, and seven core targets were analyzed and obtained. GO and KEGG pathway enrichment analysis was performed using the Metascape database. Molecular docking was conducted using AutoDockTools–1.5.6 software on some small–molecule compounds and the seven targets to evaluate the stability of binding between peppermint and core targets. Apigenin, luteolin, and ursolic acid are the three main components in peppermint. Core targets (TNF, IL–6, STAT–3, IL–1β, FGF–2, IFNG, and ESR–1) were selected based on the PPI network. The enrichment analysis suggested that the major signaling pathways in network pharmacology may include AGEs–RAGE, IL–17, NF–κB, TLRs, HIF–1, TGF–β, PI3K–Akt, and MAPK. The molecular docking results showed that one of the main components of mint, ursolic acid, exhibited good binding activity with all core targets of bovine mastitis. Other constituents also produced favorable binding with some core targets. This study elucidates the mechanisms of mint in treating bovine mastitis, providing data to support the potential development of new therapies for bovine mastitis using mint and its constituents.

Introduction. Methods of effective prevention of acute respiratory viral infections and exacerbations of chronic adenoiditis continue to be one of the topical issues of pediatric otorhinolaryngology.
Aim. To evaluate the clinical effectiveness of nasal irrigation with isotonic saline solution in children in the prevention of acute respiratory viral infections and exacerbations of chronic adenoiditis.
Material and methods. A randomized controlled trial was conducted involving 67 children aged three to fifteen years with a verified diagnosis of chronic adenoiditis. Randomization of patients was carried out by the method of envelopes into 2 groups. In patients of the 1st (main) group (n=33) with chronic adenoiditis, nasal irrigation with isotonic saline solution was performed 2 times a day for 2 months. The patients of the 2nd (control) group (n=34) were not prevented from acute respiratory viral infections using saline solutions. The comparative assessment was carried out on (0‑day) and two months later.
Results and discussions. In the studied groups, a statistically significant difference
was obtained in terms of «nasal difficulty breathing». In the main group, nasal breathing improved by 35.6 % compared with the control group (p˂0.001), rhinorrhea decreased by 40.4 % relative to the control group (p=0.002), which indicates the restoration of aeration of nasal cavity structures. A comparison of the epipharyngoscopic picture and physical examination before the use of preventive measures in children did not reveal significant differences in the groups, which indicates the similarity of clinical data. At the same time, when examined after 60 days
Conclusions. Nasal irrigation with isotonic saline solution 2 times a day, during the season of acute respiratory viral infections, is a reliable method not only to avoid the possibility of contracting this infection, but also to effectively prevent exacerbations of chronic adenoiditis.

Authors:   Ural State University named after V. I. Yakovlev, Yekaterinburg, Shcherbakova O.V.
Published: February 2025

In pursuance of the Strategy for the Development of Healthcare in the Russian Federation until 2025 (approved by Decree of the President of the Russian Federation dated 06.06.2019 No. 254), the constituent entities of the Russian Federation are responsible for developing and adopting state healthcare development programs
aimed, among other things, at eliminating the shortage of certain categories of medical
workers. At the same time, the constituent entities of the Russian Federation are given greater
independence in resolving this issue — from the choice of the form and level of the act and the
terms of these programs to specific guarantees and social support measures for medical and
pharmaceutical workers, which naturally creates regional specifics of the legislation on this
issue, which is analyzed in this article. The presented general overview of additional guarantees
and measures of social support for medical workers established in regional programs and
aimed at eliminating the shortage of personnel in the regions allows us to conclude that there
is no unified approach to establishing measures to eliminate the shortage of personnel in the
healthcare sector in the regions, as well as unified criteria for assessing the effectiveness of the
implementation of these measures.

The article examines the role of non-judicial economic expertise, which is an independent
tool for managing the activities of an economic entity and plays an important role
in various areas of economics and business. Non-judicial economic expertise allows for an
independent analysis of financial and economic indicators. With the help of such expertise,
it is possible to assess risks, identify factors affecting financial results, and make recommendations
for improving the organization’s activities, conduct a deep diagnosis of financial
indicators, which allows identifying hidden problems and weaknesses in management.
The paper proposes a classification of types of non-judicial economic expertise, a new
concept of systematization and generalization of the results of non-judicial expertise. It
is concluded that such systematization will not only organize the process of non-judicial
expert economic research, but also increase its efficiency.

Published: February 2025

This article discusses the main approaches used to determine the value of
the estimated obligation for the upcoming vacation payment, as well as various tools
to improve the accuracy of calculations or reduce their complexity. The correct calculation
of estimated liabilities, including for vacation payments, allows interested parties
to estimate the full amount of obligations of an economic entity, which in the future
will lead to an outflow of funds. In addition, a more accurate methodology for forming
estimated obligations will ensure an adequate assessment of the financial result not
only in terms of expenses incurred, but also those expenses for which the organization
has an unconditional obligation to employees.

Published: February 2025

This paper explores the complex education process in modern society, emphasizing lifelong learning as critical for personal and professional development. Despite challenges such as market saturation with university graduates, lifelong learning—including professional and retraining courses—emerges as a solution for enhancing employability. However, public awareness of its benefits remains limited, necessitating effective marketing communication to promote adult education. This paper analyses Slovak educational institutions' online platforms, mainly social media, for lifelong learning promotion. A mixed-method approach, incorporating institutional data and a survey of 633 Slovak participants, reveals a significant reliance on social media as an information source. Findings show that 81.67% of respondents obtain educational information online, with a strong preference for centralized profiles summarizing lifelong learning opportunities. Universities dominate as preferred providers, but untapped potential exists among secondary schools and language institutions. This study underscores the need for tailored digital marketing strategies in the educational sector, especially when targeting diverse demographic groups, including older adults. By leveraging social media and creating unified communication platforms, Slovak institutions can enhance lifelong learning engagement, addressing educational needs and societal demands.

Authors: Júnior José Maria e Souza , Rodrigues Elizabeth Maria Soares , Almeida Ossalin de
Published: February 2025

A poluição sonora ocupa o segundo lugar entre as formas mais comuns de poluição nas sociedades industrializadas e apresenta diversos efeitos prejudiciais à saúde humana, além dos danos auditivos. Este estudo analisou o impacto do ruído das máquinas gráficas na saúde física e mental dos servidores da UFPA, lotados na gráfica, por meio de um questionário aplicado a 10 funcionários. Os participantes, de ambos os sexos e com idades a partir de 18 anos, trabalhavam no local por pelo menos seis horas diárias. A pesquisa revelou um grande desconhecimento sobre os efeitos da poluição sonora, com a maioria dos entrevistados associando apenas à perda auditiva, sem perceber os impactos em outros órgãos, a saber a relação com arritmias cardíacas (3%), distúrbios do sono (5%) e problemas digestivos. Além disso, muitos servidores não consideram essencial o uso de Equipamentos de Proteção Individual (EPIs), embora contrariamente reconheçam sua importância. Aproximadamente 65% dos participantes não relataram problemas de saúde relacionados ao ruído, enquanto 35% atribuíram dificuldades à exposição constante ao barulho. Os dados indicam uma falta de conscientização sobre os riscos do ruído e a necessidade de um maior incentivo ao uso de EPIs. O estudo destaca ainda a urgência de ações de conscientização e a criação de campanhas educativas para informar os servidores sobre os danos do ruído à saúde, ademais de promover o uso regular dos EPIs como medida preventiva eficaz.

Authors: Trevisan Daniel
Published: February 2025

The transition to a consultative, value-centered sales approach reflects the evolution of sales practices in today's competitive market. This model goes beyond simple transactions, focusing on building long-term relationships with clients by understanding their needs and offering tailored solutions. Consulting as a sales approach allows the salesperson to position themselves as a strategic partner, helping the client achieve success and growth. Customizing solutions and using data to anticipate client needs have become crucial factors for differentiation, especially in highly competitive markets. Moreover, adopting a consultative sales strategy requires an organizational mindset geared toward continuous learning and adaptation. The effective implementation of value-based selling (VBS) depends on specific salesperson skills, such as learning orientation and networking competencies, as well as organizational support, such as value assessment tools. In times of economic crisis, rather than resorting to discounts, the consultative sales strategy proves to be a more effective alternative, as it focuses on creating genuine and sustainable value. Companies that master this approach are better positioned to grow after economic recovery. This consultative sales model represents a fundamental shift, not only in sales practice but also in how companies relate to their clients. By adopting a consultative approach, companies ensure not only an increase in sales but also customer loyalty and sustainable growth, creating a virtuous cycle of value.
The impact of sustainable practices on employee well-being and organizational success
Authors: Guares Aline
Published: February 2025

The evolution of work models, particularly the shift towards remote and hybrid work, has made employee well-being a central focus for organizations. Research shows that adopting sustainable and inclusive workplace practices that prioritize both physical and mental health significantly contributes to increased employee engagement, productivity, and overall satisfaction. The adoption of holistic well-being policies, including mental health support programs, flexible work schedules, and inclusive environments, is increasingly seen as essential for both personal and professional development. These practices not only benefit employees but also support organizational viability, aligning with global Sustainable Development Goals (SDGs), especially SDG 3, which focuses on health and well-being. Studies by Madero-Gómez et al. (2023), Singh et al. (2019), Abid et al. (2020), and others highlight the critical role of sustainable human resource management (HRM) practices in promoting employee well-being and reducing environmental impacts, creating a mutually beneficial cycle for both employees and companies. Investing in well-being strategies such as promoting mental health and offering flexible working conditions has proven to enhance organizational culture and contribute to long-term business success. The post-pandemic work environment further underscores the importance of such practices. As organizations aim to adapt to new challenges, prioritizing employee well-being and sustainability can offer a competitive advantage. Companies that implement these policies are better positioned for growth, innovation, and market adaptability, making it clear that employee well-being is integral to achieving sustainable business success.

Published: February 2025

A Síndrome do Coração Partido, também conhecida como cardiomiopatia de Takotsubo e cardiomiopatia induzida por estresse, é uma condição temporária de disfunção ventricular esquerda, que embora seja mais prevalente em mulheres entre 65 a 70 anos, a ocorrência em homens adultos também tem sido documentada, com uma variedade de etiologias identificadas. Objetivo: explorar os possíveis fatores desencadeantes da Síndrome de Takotsubo em homens adultos, na faixa etária de 19 a 44 anos. Metodologia: trata-se de uma revisão integrativa da literatura com busca realizada no banco de dados Pubmed, LILACS e Scielo, entre o período de 2014 e 2024 e seleção baseada no protocolo PRISMA. Resultados: após a análise minuciosa foram obtidos 7 relatos de caso que responderam a pergunta norteadora, bem como se enquadravam nos critérios de inclusão. Discussão e conclusão: apesar da menor incidência, a Síndrome do Coração Partido acomete o sexo masculino com fatores desencadeantes múltiplos e complexos, como abuso de anabolizantes, ruptura de feocromocitoma, esclerose múltipla, meningoencefalite, crises psicóticas e estresse emocional relacionado ao câncer. Destaca-se que o estresse físico possui papel mais significativo no desenvolvimento da síndrome quando comparado com o estresse emocional nos homens. No entanto, o estudo enfrentou limitações relacionadas ao número diminuto de dados sobre a síndrome nessa população específica, o que ilustra a necessidade de maiores pesquisas na área.

Tumor de células germinativas mediastinal é uma condição rara que pode se apresentar como massa mediastinal gigante. Um homem de 23 anos com quadro de dispneia e dor pleurítica à esquerda foi submetido a tomografia de tórax e abdome com achado de massa mediastinal anterior medindo 20,1x10,7x12,5cm, com doença localizada em tórax. Realizada biópsia aberta evidenciando tumor de células germinativas não seminoma. Sucedida quimioterapia baseada em cisplatina, com redução importante dos marcadores, porém com rápida elevação após o término do último ciclo. Foi indicada abordagem cirúrgica com ressecção completa da massa mediastinal com preservação das estruturas mediastinais e margens exíguas, confirmando a histologia: Tumor de Células germinativas misto com malignidade somática, painel amplo negativo e CD117 positivo. Apresentou boa recuperação pós-operatória, porém evoluiu a óbito após 3 meses devido a progressão de doença. Trata-se de doença com considerável mortalidade a longo prazo apesar do tratamento padrão com quimioterapia e ressecção cirúrgica

O objetivo do presente estudo foi compreender as estratégias para diagnóstico e tratamento não farmacológico da dor em neonatos nas unidades de terapia intensiva. Foi elaborada uma revisão integrativa conforme as recomendações adaptadas da diretriz Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA), com estudos disponíveis nas bases de dados PubMed e MEDLINE. Foram incluídos apenas os artigos publicados de janeiro de 2014 a dezembro de 2024, em inglês ou português. A avaliação clínica da dor em neonatos pode ser feita por meio de várias ferramentas. A Newborn Infant Parasympathetic Evaluation é a mais utilizada e frequentemente é o parâmetro de comparação na maioria dos estudos sobre as demais escalas, porque apresenta alta sensibilidade e valor preditivo positivo para avaliar a dor prolongada e processual, assim como o Skin Conductance Algesimeter, já a Premature Infant Pain Profile-Revised apresenta boa acurácia para casos de dor aguda e processual. Quanto às medidas terapêuticas não farmacológicas, destacam-se os cuidados pele-a-pele, amamentação, minimização da manipulação, enfaixamento do recém-nascido próximo à mãe, aconchego facilitado, toque humano suave, sucção não nutritiva, uso de soluções orais de sacarose e até mesmo a oferta do odor do leite materno.

Justificativa: A sífilis continua sendo um grave problema de saúde pública, principalmente em países em desenvolvimento, como o Brasil. Conhecer e divulgar os riscos de infecção por esta patologia é essencial para auxiliar nas medidas de prevenção e alertar os profissionais de saúde sobre a necessidade de investigação diagnóstica. A Profilaxia Pré-Exposição (PrEP) ao HIV é realizada com o uso de uma droga de forma programada, para evitar uma infecção por este vírus e está disponível no Brasil desde 2018.  Objetivos: Descrever o perfil de tendência da sífilis adquirida no estado do Rio de Janeiro num período de 12 anos e especular se o uso da PrEP poderia influenciar no aumento de casos de sífilis no estado do Rio de Janeiro. Metodologia: Este é um estudo ecológico sobre Sífilis Adquirida nos últimos 12 anos (2012 a 2023) no estado do Rio de Janeiro. Os dados foram coletados no Sistema de Informação de Agravos de Notificação (SINAN). Resultados: As notificações de Sífilis Adquirida foram computadas em dois períodos distintos: 6 anos que antecedem a PrEP (2012 a 2017) e 6 anos Pós-PrEP (2018 a 2023). No período Pré-PrEP foram notificados 31.145 casos (60% masculino) e no período Pós-PrEP as notificações contabilizaram 114.053 casos (60% masculino). Os casos de Sífilis adquirida triplicaram (3,6 mais casos) após a insitutição da PrEP no estado do Rio de Janeiro. Conclusões: Nossa pesquisa confirmou uma estreita relação entre o aumento dos casos de sífilis em pessoas que utiliazaram a PrEP. Para o Rio de Janeiro são necessárias intervenções integradas de testagem e prevenção de IST, para mitigar a aquisição e transmissão de sifilis entre os usuários de PrEP.
Síndrome de Infusão de Propofol: um relato de caso
Authors: Magalhães Victor Augusto Rocha , Gonçalves Ana Carolina , Gontijo Patrícia Guimarães Barcelos
Published: February 2025

O propofol, exemplar de anestésico e sedativo, atua potencializando o neurotransmissor GABA, resultando em um efeito de hipnose e de sedação. Dentre as suas reações adversas, a Síndrome de Infusão do Proporol (PRIS) é uma complicação rara, mas potencialmente fatal. Esta condição ocorre devido a um distúrbio do metabolismo energético, com acúmulo de ácidos graxos na matriz mitocondrial. O quadro clínico da PRIS caracteriza-se por múltiplas disfunções orgânicas como acidose metabólica, arritmias, rabdomiólise, insuficiência renal e achados laboratoriais de hipertrigliceridemia e de plasma lipêmico. Tal condição apresenta como principal fator de risco a administração do propofol por tempo e dose prolongados. O manejo desta patologia preconiza a suspensão da medicação e terapias de suporte das complicações associadas. Assim, o presente estudo objetiva relatar o caso de um paciente sugestivo de PRIS durante infusão desse medicamento em ambiente de terapia intensiva.

As reações alérgicas são respostas exacerbadas do sistema imunológico a substâncias diversas, podendo impactar significativamente a qualidade de vida dos indivíduos afetados. A prevalência dessas condições, especialmente entre crianças, continua a aumentar devido a fatores genéticos e ambientais. Diante desse contexto, o presente estudo objetiva analisar o perfil clínico e epidemiológico de pacientes pediátricos atendidos em um ambulatório especializado, buscando identificar os fatores mais prevalentes associados ao desenvolvimento e manejo das doenças alérgicas. Para isso, foi feita uma pesquisa longitudinal, descritiva e prospectiva, com entrevistas direcionadas a pacientes de 0 a 18 anos ou seus responsáveis. Os resultados evidenciaram uma alta prevalência de asma e rinite alérgica, frequentemente associadas a fatores como poeira e mudanças de temperatura, além de um histórico familiar significativo de alergias. Apesar de a maioria dos pacientes relatar controle satisfatório dos sintomas, ainda foram identificadas barreiras na adesão ao tratamento e no controle ambiental. Logo, intervenções educativas e estratégias de manejo personalizado são essenciais para otimizar o controle das doenças alérgicas, além de reforçar a importância do acompanhamento precoce e do suporte ao ambiente familiar. O estudo contribui para direcionar ações mais eficazes em saúde pública e manejo clínico.

A retocolite ulcerativa (RCU) é uma doença inflamatória intestinal crônica que afeta predominantemente a mucosa do cólon e do reto, caracterizando-se por um padrão inflamatório ascendente e contínuo. Sua fisiopatologia envolve uma resposta imunológica exacerbada contra componentes luminais, resultando em inflamação persistente e dano tissular. A interação entre predisposição genética, alterações na microbiota intestinal e fatores ambientais, como dieta e estilo de vida, desempenha um papel crucial na sua patogênese. Embora a etiologia exata ainda não esteja completamente elucidada, evidências apontam para um desequilíbrio entre mecanismos imunorregulatórios e fatores externos. As manifestações clínicas da RCU variam conforme a extensão e gravidade da doença, podendo incluir diarreia crônica com sangue, dor abdominal, urgência evacuatória, tenesmo e perda de peso. Em casos mais graves, podem surgir complicações como megacólon tóxico, perfuração intestinal e risco aumentado de câncer colorretal. O diagnóstico baseia-se em uma combinação de história clínica, exames laboratoriais, colonoscopia com biópsia e testes de imagem, permitindo a diferenciação de outras doenças intestinais. O tratamento da RCU envolve o uso de anti-inflamatórios, imunossupressores e terapias biológicas, além da adoção de estratégias individualizadas para minimizar os sintomas e prevenir recorrências. Em casos refratários, a cirurgia pode ser necessária. A nutrição desempenha um papel essencial no manejo da doença, sendo importante manter uma alimentação equilibrada para reduzir deficiências nutricionais e modular a resposta inflamatória. O prognóstico da RCU depende da gravidade e da resposta ao tratamento, podendo variar de controle satisfatório com terapia medicamentosa até complicações graves que requerem intervenção cirúrgica. As direções futuras incluem o desenvolvimento de novas terapias biológicas, estudos sobre o papel da microbiota intestinal e abordagens personalizadas para otimizar o tratamento e melhorar a qualidade de vida dos pacientes.
