In Vitro Biofilm Formation Kinetics of <i>Pseudomonas aeruginosa</i> and <i>Escherichia coli</i> on Medical-Grade Polyether Ether Ketone (PEEK) and Polyamide 12 (PA12) Polymers

Susana Carbajal-Ocaña, Kristeel Ximena Franco-Gómez, Valeria Atehortúa-Benítez et al.

Biofilms, structured communities of microorganisms encased in an extracellular matrix, are a major cause of persistent infections, particularly when formed on medical devices. This study investigated the kinetics of biofilm formation by <i>Escherichia coli</i> and <i>Pseudomonas aeruginosa</i>, two clinically significant pathogens, on two medical-grade polymers: polyether ether ketone (PEEK) and polyamide 12 (PA12). Using a modified crystal violet staining method and spectrophotometric quantification, we evaluated biofilm development over time on polymer granules and catheter segments composed of these materials. Results revealed that PEEK surfaces supported significantly more biofilm formation than PA12, with peak accumulation observed at 24 h for both pathogens. Conversely, PA12 demonstrated reduced bacterial adhesion and lower biofilm biomass, suggesting surface characteristics less conducive to microbial colonization. Additionally, the study validated a reproducible protocol for assessing biofilm formation, providing a foundation for evaluating anti-biofilm strategies. While the assays were performed under static in vitro conditions, the findings highlight the importance of material selection and early prevention strategies in the design of infection-resistant medical devices. This work contributes to the understanding of how surface properties affect microbial adhesion and underscores the critical need for innovative surface modifications or coatings to mitigate biofilm-related healthcare risks.

Siti Rahmah Hidayatullah Lubis, Nuranisa Mu'minah

Introduction: Psychosocial hazards are significant threats to the safety and health of workers, particularly in industries such as production. Based on preliminary observations, assembly workers in the production setting, known for requiring precision, face increased risk, specifically when confronted with elevated demand. Therefore, this study aimed to analyze psychosocial hazards among production workers at PT. Sarandi Karya Nugraha. Method: Qualitative descriptive approach was utilized for a case study conducted at PT. Sarandi Karya Nugraha from July to October 2020. A total of 4 informants was selected by purposive methods, and data were collected through in-depth interviews, observations, and document reviews. Meanwhile, thematic analysis was used to analyze the details obtained. Result: The results showed that there are 6 psychosocial hazard themes within the production department. These comprised role ambiguity, role conflict, quantitative workload, qualitative workload, responsibility to others, and career development. In addition, issues related to role conflict, quantitative overload, and career development persisted in the company. Conclusion: Organizations should create plans, policies, and opportunities for workers in the production department to gain assurance regarding career advancement. Additionally, a detailed description of work process in situations comprising quantitative workload should be created.

Specific Personal Hygiene Procedures and Practices in Food Handlers—A Cross-Sectional Study in Butcher and Fishmonger Shops in Almada

Inês Oliveira, Miguel Almeida, João J. Ferreira Gomes et al.

Good manufacturing practices play an important role in obtaining safe food and preventing foodborne diseases. To achieve this goal, food handlers must receive appropriate training to be aware of their responsibilities. In this work, compliance with specific personal hygiene requirements by food handlers was assessed in a cross-sectional study of traditional small retail establishments, namely butcher (<i>n</i> = 56) and fishmonger (<i>n</i> = 17) shops in Almada, Portugal. Food handlers (<i>n</i> = 140, of which 113 worked in butcher shops, and 27 worked in fishmonger shops) were interviewed for data collection, and retail establishments were audited considering specific hygiene requisites. In fishmonger shops, most food handlers are women (89%), aged 18 to 45 years (70%), with a high school degree, having worked for less than 5 years in this activity, while in butcher shops most food handlers are men (90%) over 45 years old (58%), with a basic education level, and more than 26 years of experience. Most food handlers (>95%) attended recent food safety and hygiene training courses and were able to recognize that hand sanitizers cannot replace a proper hand wash, and to identify <i>Staphylococcus aureus</i> transmission routes to food. However, approximately 23% of retail establishments failed to provide hot water in the handwashing basin and exhibited improper placement of handwashing instructions. Furthermore, these establishments did not implement corrective actions following non-conforming microbiological results of hand hygiene monitoring. These findings reinforce the need for consistent management commitment, and for providing food handlers with regular training, which is crucial for maintaining a strong food safety and hygiene culture in these traditional small retail establishments.

The discovery of regional neurotoxicity-associated metabolic alterations induced by carbon quantum dots in brain of mice using a spatial metabolomics analysis

Min Chen, Siyuan Chen, Xinyu Wang et al.

Abstract Background Recently, carbon quantum dots (CQDs) have been widely used in various fields, especially in the diagnosis and therapy of neurological disorders, due to their excellent prospects. However, the associated inevitable exposure of CQDs to the environment and the public could have serious severe consequences limiting their safe application and sustainable development. Results In this study, we found that intranasal treatment of 5 mg/kg BW (20 µL/nose of 0.5 mg/mL) CQDs affected the distribution of multiple metabolites and associated pathways in the brain of mice through the airflow-assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI) technique, which proved effective in discovery has proven to be significantly alerted and research into tissue-specific toxic biomarkers and molecular toxicity analysis. The neurotoxic biomarkers of CQDs identified by MSI analysis mainly contained aminos, lipids and lipid-like molecules which are involved in arginine and proline metabolism, biosynthesis of unsaturated fatty acids, and glutamine and glutamate metabolism, etc. as well as related metabolic enzymes. The levels or expressions of these metabolites and enzymes changed by CQDs in different brain regions would induce neuroinflammation, organelle damage, oxidative stress and multiple programmed cell deaths (PCDs), leading to neurodegeneration, such as Parkinson’s disease-like symptoms. This study enlightened risk assessments and interventions of QD-type or carbon-based nanoparticles on the nervous system based on toxic biomarkers regarding region-specific profiling of altered metabolic signatures. Conclusion These findings provide information to advance knowledge of neurotoxic effects of CQDs and guide their further safety evaluation.

Estela Hernández Runque, Jesús Salvador Hernández Romero

Introducción: La actividad del ser humano no puede ser ajena a las interrelaciones hombre-trabajo y entorno, pues estas relaciones pueden traer consigo condiciones disergonómicas que pueden tener un impacto negativo en la salud. Objetivo: Evaluar las condiciones disergonómicas en una unidad de procesamiento logístico durante el mes de julio de 2021. Métodos: El estudio se enmarcó dentro el paradigma cuantitativo, con un diseño no experimental, de campo, de nivel descriptivo y corte transversal, con enfoque ergonómico, la población estuvo conformada por 9 trabajadores. Los instrumentos utilizados fueron el Cuestionario Nórdico estandarizado, el método REBA y la ecuación de la NIOHS. El análisis de datos se realizó a través de Microsoft Excel 2010®. Resultados: El 31 % de los trabajadores manifestó dolor de espalda baja. A partir del análisis del método REBA se evidenció que, en la actividad de selección de gaveras, existen posturas con un nivel de riesgo medio y alto. La actividad selección y reparación de estibas posee puntuaciones REBA entre 9 y 12 puntos, con niveles de riesgos alto y muy alto. La aplicación de la ecuación de NIOSH en la actividad selección de gaveras mostró el índice de levantamiento compuesto igual a 1,4 interpretado como un incremento moderado del riesgo. Conclusiones: Las actividades ejecutadas en la unidad de procesamiento logístico poseen un factor de riesgo importante para el desarrollo de trastornos musculoesqueléticos. Además, las dolencias manifestadas por los trabajadores pueden estar relacionadas con la manipulación manual de cargas y posturas incómodas presentes en la realización de estas actividades Introduction: The human being’s activities cannot be disconnected from the interrelationships man-work and environment, since these relationships can bring about disergonomic conditions that can have a negative impact on health. Objective: To evaluate the disergonomic conditions at a logistics processing unit during the month of July 2021. Methods: The study was framed within the quantitative paradigm, with a nonexperimental, field, descriptive and cross-sectional design, as well as an ergonomic approach. The population consisted of 9 workers. The used instruments were the standardized Nordic questionnaire, the REBA (Rapid Entire Body Assessment) method and the National Institute for Occupational Safety and Health (NIOSH) equation. Data analysis was performed using Microsoft Excel 2010®. Results: 31% of the workers reported low back pain. The analysis of the REBA method permitted to observe that, in the activity of selecting boxes, there are body positions with medium or high risk levels. The activity of selecting and repairing pallets has REBA scores between 9 and 12 points, with high or very high risk levels. The application of the NIOSH equation into the activity of selecting boxes showed the composite lifting index equal to 1.4, interpreted as a moderate increase in risk. Conclusions: The activities carried out in the logistics processing unit present an important risk factor for the development of musculoskeletal disorders. In addition, the ailments reported by the workers may be related to the manual handling of loads and the uncomfortable postures for carrying out these activities

Experimental study of the specificity of morphological changes development in internal organs with prolonged exposure to coal-rock dust and sodium fluoride to the body

M. S. Bugaeva, O. Bondarev, L. G. Gorokhova et al.

Introduction. Occupational diseases detected at occupational examinations - pneumoconiosis and fluorosis - are, as a rule, chronic, the initial stages of development are almost asymptomatic. Industrial dust affects only the respiratory organs. Specific sign of fluoride intoxication is a lesion of the musculoskeletal system. The information available in the literature on the systemic manifestations of these diseases is not numerous. In this regard, it is relevant to study the early morphological changes, the timing of their occurrence and the features of development, depending on the specificity of the production factor. The study aims to experimentally identify the specificity of the development of morphological changes in organs and tissues under prolonged exposure to harmful production factors: coal-rock dust and sodium fluoride. Materials and methods. The authors conducted studies on adult white male laboratory rats. Scientists studied the features of the development of morphological changes in the bronchopulmonary system, heart, liver and kidneys in the dynamics of the impact of production factors on experimental models of anthracosilicosis and chronic fluoride intoxication. For histological examination, specialists carried out organ sampling in animals after 1, 3, 6, 9, 12 weeks of the experime Results. Chronic exposure to coal-rock dust, as well as sodium fluoride, leads to the development of compensatory and adaptive changes in the internal organs in the early stages of the experiment before the formation of degenerative and fibroplastic disorders of the stromal and parenchymal components in the later stages. Inhalation of coal-rock dust creates in experimental animals by an early breakdown of the adaptive mechanisms of the respiratory system and heart muscle. There is a formation from the 6th week of the experiment of pneumosclerosis with the spread to the air-conducting structures, atrophy of the bronchial mucosa, degenerative changes in cardiomyocytes. Despite the early formation of stroma fibrosis, reparative processes restrain dystrophic cell changes in the liver and kidneys. All this develops by the 9th week of the experiment. The accumulation of sodium fluoride leads to the early formation of pronounced protein dystrophy of the liver and kidney parenchyma with the development of necrotic changes by the 6-9 weeks of the experiment. Disorders in the bronchopulmonary system before the 9th week of exposure are of the nature of immune inflammation with the subsequent development of degenerative changes in the air-conducting structures. The heart has moderate dystrophy throughout the experiment. Regardless of the influencing factor, changes in the vessels of the studied organs at the initial stages of the experiment lead to hypertrophy of smooth muscle cells of the media and intima, followed by the development of endotheliosis and hyalinosis. Limitations. The results of the histological examination are descriptive of pathomorphological changes in the bronchopulmonary system, heart muscle, liver and kidneys. We did not conduct a morphometry of various structures of the studied organs has not been carried out with subsequent statistical processing of the results obtained. In this regard, when studying the specifics of the development of morphological changes depending on the influencing harmful production factor, the compared indicators were the first morphological changes and the timing of their formation. Conclusions. The obtained results have theoretical and practical significance for the development of recommendations for timely preventive and organ-specific therapeutic measures in the premorbid period of the development of occupational diseases. Ethics. The researchers conducted maintenance, feeding and removal of animals from the experiment in accordance with the requirements of the Order of the Ministry of Health of the Russian Federation "On approval of the Rules of Good Laboratory Practice" (No. 199n of 01.04.2016), as well as the Guide for the Maintenance and Use of Laboratory Animals (Guide for the Care and Use of Laboratory Animals, 1996). Scientists received permission from the Bioethical Committee of the Research Institute of Complex Problems of Hygiene and Occupational Diseases to conduct the study.

Dimethylarginine dimethylaminohydrolase 1 protects PM2.5 exposure-induced lung injury in mice by repressing inflammation and oxidative stress

Junling Gao, Tong Lei, Hongyun Wang et al.

Abstract Background Airborne fine particulate matter with aerodynamic diameter ≤ 2.5 μm (PM2.5) pollution is associated with the prevalence of respiratory diseases, including asthma, bronchitis and chronic obstructive pulmonary disease. In patients with those diseases, circulating asymmetric dimethylarginine (ADMA) levels are increased, which contributes to airway nitric oxide deficiency, oxidative stress and inflammation. Overexpression of dimethylarginine dimethylaminohydrolase 1 (DDAH1), an enzyme degrading ADMA, exerts protective effects in animal models. However, the impact of DDAH1/ADMA on PM2.5-induced lung injury has not been investigated. Methods Ddah1 −/− and DDAH1-transgenic mice, as well as their respective wild-type (WT) littermates, were exposed to either filtered air or airborne PM2.5 (mean daily concentration ~ 50 µg/m3) for 6 months through a whole-body exposure system. Mice were also acutely exposed to 10 mg/kg PM2.5 and/or exogenous ADMA (2 mg/kg) via intratracheal instillation every other day for 2 weeks. Inflammatory response, oxidative stress and related gene expressions in the lungs were examined. In addition, RAW264.7 cells were exposed to PM2.5 and/or ADMA and the changes in intracellular oxidative stress and inflammatory response were determined. Results Ddah1 −/− mice developed more severe lung injury than WT mice after long-term PM2.5 exposure, which was associated with greater induction of pulmonary oxidative stress and inflammation. In the lungs of PM2.5-exposed mice, Ddah1 deficiency increased protein expression of p-p65, iNOS and Bax, and decreased protein expression of Bcl-2, SOD1 and peroxiredoxin 4. Conversely, DDAH1 overexpression significantly alleviated lung injury, attenuated pulmonary oxidative stress and inflammation, and exerted opposite effects on those proteins in PM2.5-exposed mice. In addition, exogenous ADMA administration could mimic the effect of Ddah1 deficiency on PM2.5-induced lung injury, oxidative stress and inflammation. In PM2.5-exposed macrophages, ADMA aggravated the inflammatory response and oxidative stress in an iNOS-dependent manner. Conclusion Our data revealed that DDAH1 has a marked protective effect on long-term PM2.5 exposure-induced lung injury.

Titanium dioxide and carbon black nanoparticles disrupt neuronal homeostasis via excessive activation of cellular prion protein signaling

Luiz W. Ribeiro, Mathéa Pietri, Hector Ardila-Osorio et al.

Abstract Background Epidemiological emerging evidence shows that human exposure to some nanosized materials present in the environment would contribute to the onset and/or progression of Alzheimer’s disease (AD). The cellular and molecular mechanisms whereby nanoparticles would exert some adverse effects towards neurons and take part in AD pathology are nevertheless unknown. Results Here, we provide the prime evidence that titanium dioxide (TiO2) and carbon black (CB) nanoparticles (NPs) bind the cellular form of the prion protein (PrPC), a plasma membrane protein well known for its implication in prion diseases and prion-like diseases, such as AD. The interaction between TiO2- or CB-NPs and PrPC at the surface of neuronal cells grown in culture corrupts PrPC signaling function. This triggers PrPC-dependent activation of NADPH oxidase and subsequent production of reactive oxygen species (ROS) that alters redox equilibrium. Through PrPC interaction, NPs also promote the activation of 3-phosphoinositide-dependent kinase 1 (PDK1), which in turn provokes the internalization of the neuroprotective TACE α-secretase. This diverts TACE cleavage activity away from (i) TNFα receptors (TNFR), whose accumulation at the plasma membrane augments the vulnerability of NP-exposed neuronal cells to TNFα -associated inflammation, and (ii) the amyloid precursor protein APP, leading to overproduction of neurotoxic amyloid Aβ40/42 peptides. The silencing of PrPC or the pharmacological inhibition of PDK1 protects neuronal cells from TiO2- and CB-NPs effects regarding ROS production, TNFα hypersensitivity, and Aβ rise. Finally, we show that dysregulation of the PrPC-PDK1-TACE pathway likely occurs in the brain of mice injected with TiO2-NPs by the intra-cerebro-ventricular route as we monitor a rise of TNFR at the cell surface of several groups of neurons located in distinct brain areas. Conclusion Our in vitro and in vivo study thus posits for the first time normal cellular prion protein PrPC as being a neuronal receptor of TiO2- and CB-NPs and identifies PrPC-coupled signaling pathways by which those nanoparticles alter redox equilibrium, augment the intrinsic sensitivity of neurons to neuroinflammation, and provoke a rise of Aβ peptides. By identifying signaling cascades dysregulated by TiO2- and CB-NPs in neurons, our data shed light on how human exposure to some NPs might be related to AD.

Some dilemmas of economic democracy: Indicators and empirical analysis

M. Zafirovski

The article addresses certain current and recurring dilemmas concerning economic or industrial democracy in modern society. First, it identifies the main indicators and proxies of economic democracy. Then it undertakes an empirical analysis and calculation of levels of economic democracy among contemporary Western and related societies, specifically the OECD countries, and compares and ranks these accordingly. It concludes that the type of economy such as that denoted by the variety of capitalism primarily explains and predicts these variations in economic democracy among OECD countries. Specifically, a ‘rationally regulated social economy’ in the form of regulated, welfare capitalism determines and predicts the highest level of economic democracy. Especially the continental Western ‘European social model’ via welfare capitalism is determinative and predictive of the highest levels of economic democracy in its multiple dimensions, including high collective bargaining coverage, widespread codetermination, strong employment protection and others. Conversely, an unregulated economy such as unrestrained, plutocratic capitalism that the American model epitomizes tends to cause and predict the lowest level of economic democracy. A mixed economy such as hybrid or residual capitalism causes levels of economic democracy lower and higher than those of regulated, welfare and unrestrained, plutocratic capitalisms, respectively. Overall, the article builds on and contributes to the literature and analysis of economic and industrial democracy in modern society.

Fighting Youth Unemployment

T. Chevalier

The chapter stresses that the transition to a post-industrial society has consequences on the life course, and especially on the transition from childhood to adulthood. However, this transition varies significantly between countries, because of different institutional arrangements. Accordingly, the chapter analyzes these different arrangements of socio-economic institutions, including education, labor market policies, and welfare policies (with student support), by presenting the typology of “youth welfare citizenship regimes.” The second part of the chapter proceeds to four “typical” case studies showing how different growth regimes presented in the first chapter shape these youth welfare citizenship regimes (France, Germany, Sweden, and the United Kingdom). Then it analyzes how growth strategies (the reforms implemented by governments in order to boost growth and job creation) have recently been influencing the evolution of youth citizenship regimes, especially through reforms of active labor market policies (ALMP) that aim to fight youth unemployment. The argument here is not causal but rather contextual and systemic, and the objective of the case studies is therefore to present the coherence between a growth regime and the way socio-economic institutions structure the entry into adulthood, leading to a specific youth welfare citizenship regime, and how reforms inspired by a specific growth strategy contributes to transform youth welfare regime.

High reliability organisations and collective mindfulness for improving healthcare safety management: a scoping review protocol of factors, measures and instruments

Manikam Pillay, Andrew Enya, Emmanuel Bannor Boateng

A growing body of peer-reviewed studies demonstrate the importance of high-reliability organisations and collective mindfulness in improving healthcare safety. However, limited attention has been devoted to developing a common set of characteristics, dimensions, indicators and instruments for measuring collective mindfulness. This can limit its operationalisation and ability to benchmark. This protocol outlines the key procedures that will be used to conduct a scoping literature review, in order to summarise key definitions; identify theoretical underpinnings, dimensions, measures and instruments; and develop a theoretical model to advance research and practice. Specifically, a five-step process and the Preferred Reporting Instruments for Systematic and Meta-Analyses will be used to search, screen and select literature published in five electronic databases. Keywords will include a combination of ‘high-reliability organisations’, high-reliability theory’ with ‘health care’, ‘patient safety’, ‘medical errors’, ‘medical mistakes’, ‘medication error’. A double-blind process will be used for searching, screening and selection of abstracts and full-articles, and inter-observer agreement assessed using Cohen’s kappa.

Audiological analysis in military police officers with exposure to occupational noise in motorized patrol activity

K.C.S. de Lima, L.B. da Silva, V.S.B. Gonçalves et al.

The aim of this article is to present the results of audiological findings from a selection of military police officers with exposure to occupational noise, in the motorized patrol activity, in João Pessoa city. The data collected from the motorcycle police sample were compared with the ISO 1999: 2013 Standard. The research was performed in 46 police officers, whose mean age was 32.7 years old and a mean service time of 10.5 years. For the subjects’ selection and inclusion in the study, interviews were conducted, in addition to questionnaires, ontological examination, audiometric tests and the respective noise level measurements performed by a personal dosimeter, according to ISO 9612:2009 Standard recommendations. Findings from questionnaires showed that 51% of the police officers reported to have some type of hearing complaints; through audiometric tests, 36.1% of the cases suggested hearing loss. The most significant hearing threshold change occur in the range from 3000Hz and 4000Hz. Hearing thresholds shifts suggest the occurrence of some Noise Induced Hearing Loss (NIHL) level in motorcycle police officers who are over 30 years and 10 years of service. Besides, compared with the data from ISO 1999:2013 standard, there is a decrease in the auditory level of these professionals after three years on service, and a noise exposure of Lex, 8h = 96.9 dB(A).
