Biliothorax: A Rare Case of Dyspnea.

Biliothorax is the presence of bile in the pleural cavity. This condition is rare, and it usually results as a complication of hepatobiliary procedures. The authors present a case of an 87-year-old female who was admitted to the emergency department with the acute onset of severe dyspnea. A chest X-ray and CT revealed a large right-lung pleural effusion that, after thoracentesis, confirmed the presence of biliothorax. It is important to consider this entity when confronted with an effusion liquid of a dark greenish color, as a delay in diagnosis and management may be life-threatening.

Diversity and distribution of iron-oxidising bacteria belonging to Gallionellaceae in different sites of a hydroelectric power plant.

Iron (Fe) is the fourth most abundant element on the planet, and iron-oxidising bacteria (FeOB) play an important role in the biogeochemical cycle of this metal in nature. FeOB stands out as Fe oxidisers in microaerophilic environments, and new members of this group have been increasingly discussed in the literature, even though their isolation can still be challenging. Among these bacteria is the Gallionellaceae family, mainly composed of neutrophilic FeOB, highlighting Gallionella ferruginea, and nitrite-oxidiser genera. In the previous metagenomic study of the biofilm and sediments of the cooling system from the Irapé hydroelectric power plant (HPP-Irapé), 5% of the total bacteria sequences were related to Gallionellaceae, being 99% unclassified at genus level. Thus, in the present study, a phylogenetic tree based on this family was constructed, in order to search for shared and unique Gallionellaceae signatures in a deep phylogenetic level affiliation and correlated them with geomorphologic characteristics. The results revealed that Gallionella and Ferrigenium were ubiquitous reflecting their ability to adapt to various locations in the power plant. The cave was considered a hotspot for neutrophilic FeOB since it harboured most of the Gallionellaceae diversity. Microscopic biosignatures were detected only in the CS1 sample, which presented abundance of the stalk-forming Ferriphaselus and of the sheath-forming Crenothrix. Further studies are required to provide more detailed insights on Gallionellaceae distribution and diversity patterns in hydroelectric power plants, particularly its biotechnological potential in this industry.

Acute Exposure to Two Biocides Causes Morphological and Molecular Changes in the Gill Ciliary Epithelium of the Invasive Golden Mussel Limnoperna fortunei (Dunker, 1857).

Limnoperna fortunei, the golden mussel, is a bivalve mollusk considered an invader in South America. This species is responsible for ecological and economic damages due to its voluminous fouling capability. Chemical biocides such as MXD-100™ and sodium dichloroisocyanurate (NaDCC) are often used to control L. fortunei infestations in hydraulic systems. Thus, we proposed to investigate the effects of different periods (24, 48 and 72 h) of exposure to MXD-100™ (0.56 mg L-1) and NaDCC (1.5 mg L-1) on the gills of L. fortunei through morphological and molecular analyses. NaDCC promoted progressive morphological changes during the analyzed periods and only an upregulation of SOD and HSP70 expression during the first 24 h of exposure. MXD-100™ led to severe morphological changes from the first period of exposure, in addition to an upregulation of SOD, CAT, HSP70 and CYP expression during the first 24 h. In contrast, MXD-100™ led to a downregulation of CAT transcription between 24 and 48 h. In static conditions, NaDCC causes lethal damage after 72 h of exposure, and that exposure needs to be continuous to achieve the control of the species. Meanwhile, the MXD-100™ treatment presented several effects during the first 24 h, showing acute toxicity in a shorter period of time.

Machine Learning Based Method for Impedance Estimation and Unbalance Supply Voltage Detection in Induction Motors.

Induction motors (IMs) are widely used in industrial applications due to their advantages over other motor types. However, the efficiency and lifespan of IMs can be significantly impacted by operating conditions, especially Unbalanced Supply Voltages (USV), which are common in industrial plants. Detecting and accurately assessing the severity of USV in real-time is crucial to prevent major breakdowns and enhance reliability and safety in industrial facilities. This paper presented a reliable method for precise online detection of USV by monitoring a relevant indicator, denominated by negative voltage factor (NVF), which, in turn, is obtained using the voltage symmetrical components. On the other hand, impedance estimation proves to be fundamental to understand the behavior of motors and identify possible problems. IM impedance affects its performance, namely torque, power factor and efficiency. Furthermore, as the presence of faults or abnormalities is manifested by the modification of the IM impedance, its estimation is particularly useful in this context. This paper proposed two machine learning (ML) models, the first one estimated the IM stator phase impedance, and the second one detected USV conditions. Therefore, the first ML model was capable of estimating the IM phases impedances using just the phase currents with no need for extra sensors, as the currents were used to control the IM. The second ML model required both phase currents and voltages to estimate NVF. The proposed approach used a combination of a Regressor Decision Tree (DTR) model with the Short Time Least Squares Prony (STLSP) technique. The STLSP algorithm was used to create the datasets that will be used in the training and testing phase of the DTR model, being crucial in the creation of both features and targets. After the training phase, the STLSP technique was again used on completely new data to obtain the DTR model inputs, from which the ML models can estimate desired physical quantities (phases impedance or NVF).

Linking microbial slime community structure with abiotic factors and antifouling strategy in hydroelectric cooling systems.

Microfouling can have significant economic impacts for hydroelectric power plants. However, knowledge concerning the composition and metabolism of microbial biofilm in cooling systems remains scarce. We examined the metagenome present in a cooling system, comprising a filter (F) and heat exchanger (HE), in the Nova Ponte hydroelectric power plant in Brazil, to identify bacteria and pathways that could be targeted to monitor and control biofilm formation. Our data revealed that the microfouling sample from heat exchanger 1 (HEM1), with porous consistency, presented enriched bacterial members not frequently described as biofilm formers in cooling systems, besides it has been shown to be an autoinducer repression pathway. Furthermore, the microfouling sample from heat exchanger 2 (HEM2), with gelatinous consistency, seemed to be an established biofilm, containing enriched bacterial groups such as Desulfotomaculum and Crenothrix and autoinducers, with biotechnological relevance in industrial biofilms. The results demonstrate that biofilm composition will vary depending on different abiotic conditions and the antifouling strategy used, including type of compound, concentration, and frequency of use. Therefore, all these variables must be evaluated when a power plant is affected by microbial slime in the cooling system. Our findings could help to define strategies for efficient and ecofriendly measures to contain microfouling in power plants.

Psychometric properties of the online Satisfaction with Life Scale in university students from a low-income region.

PURPOSE: To test the feasibility, reliability, and validity of the Satisfaction with Life Scale (SWLS) in an online format in university students from a low-income region. METHODS: This was a psychometric study, involving a study of reliability (n = 117) and validity (n = 195) in university students from a region with a Gini index of 0.56. The scale was applied at two time points with an interval of 2 weeks. This scale measures satisfaction with life based on five statements and responses ranging from 1 to 7 (strongly disagree to strongly agree). We conducted the reliability assessment using temporal stability and internal consistency and construct validity assessment by internal structure solution. RESULTS: All SWLS items showed acceptable (rho > 0.30) and significant (p < 0.05) temporal stability and acceptable internal consistency (alpha > 0.70). In construct validity (internal structure), we identified a factor with an explained variance of 59.0% in the exploratory factor analysis. Additionally, in the confirmatory factor analysis, we identified a one-factor structure solution for SWLS with an acceptable model fitting (chi-square/degrees of freedom [X2/df] = 6.53; Tucker-Lewis Index [TLI] = 0.991; Comparative Fit Index [CFI] = 0.996; root mean square error of approximation [RMSEA] = 0.040; standardized root mean-squared residual [SRMR] = 0.026). CONCLUSION: The Satisfaction with Life Scale, in the online format, is a reliable and valid tool for university students in a low-income context.

Online Monitoring of Sensor Calibration Status to Support Condition-Based Maintenance.

Condition-Based Maintenance (CBM), based on sensors, can only be reliable if the data used to extract information are also reliable. Industrial metrology plays a major role in ensuring the quality of the data collected by the sensors. To guarantee that the values collected by the sensors are reliable, it is necessary to have metrological traceability made by successive calibrations from higher standards to the sensors used in the factories. To ensure the reliability of the data, a calibration strategy must be put in place. Usually, sensors are only calibrated on a periodic basis; so, they often go for calibration without it being necessary or collect data inaccurately. In addition, the sensors are checked often, increasing the need for manpower, and sensor errors are frequently overlooked when the redundant sensor has a drift in the same direction. It is necessary to acquire a calibration strategy based on the sensor condition. Through online monitoring of sensor calibration status (OLM), it is possible to perform calibrations only when it is really necessary. To reach this end, this paper aims to provide a strategy to classify the health status of the production equipment and of the reading equipment that uses the same dataset. A measurement signal from four sensors was simulated, for which Artificial Intelligence and Machine Learning with unsupervised algorithms were used. This paper demonstrates how, through the same dataset, it is possible to obtain distinct information. Because of this, we have a very important feature creation process, followed by Principal Component Analysis (PCA), K-means clustering, and classification based on Hidden Markov Models (HMM). Through three hidden states of the HMM, which represent the health states of the production equipment, we will first detect, through correlations, the features of its status. After that, an HMM filter is used to eliminate those errors from the original signal. Next, an equal methodology is conducted for each sensor individually and using statistical features in the time domain where we can obtain, through HMM, the failures of each sensor.

Effects of syntactic structure on the processing of lexical repetition during sentence reading.

Previous research has demonstrated that the ease or difficulty of processing complex semantic expressions depends on sentence structure: Processing difficulty emerges when the constituents that create the complex meaning appear in the same clause, whereas difficulty is reduced when the constituents appear in separate clauses. The goal of the current eye-tracking-while-reading experiments was to determine how changes to sentence structure affect the processing of lexical repetition, as this manipulation enabled us to isolate processes involved in word recognition (repetition priming) from those involved in sentence interpretation (felicity of the repetition). When repetition of the target word was felicitous (Experiment 1), we observed robust effects of repetition priming with some evidence that these effects were weaker when repetition occurred within a clause versus across a clause boundary. In contrast, when repetition of the target word was infelicitous (Experiment 2), readers experienced an immediate repetition cost when repetition occurred within a clause, but this cost was eliminated entirely when repetition occurred across clause boundaries. The results have implications for word recognition during reading, processes of semantic integration, and the role of sentence structure in guiding these linguistic representations.

Speed Estimation of Six-Phase Induction Motors, Using the Rotor Slot Harmonics.

Multiphase machines have recently been promoted as a viable alternative to traditional three-phase machines. Most experts are looking for strategies to estimate the rotation speed of such complex systems, since speed data are required for high-performance control purposes. Traditionally, electromechanical sensors were used to detect the rotor speed of electric motors. These devices are extremely accurate, but they are also delicate and costly to deploy. New speed estimating algorithms must be created for these situations. This paper looks at how to estimate rotor speed in symmetrical six-phase induction motors (IMs) using a novel strategy for rotor speed estimation based on the Short Time Fourier Transform (STFT) method. The technique is based on tracking the frequencies of the rotor slot harmonics (RSH) seen in most squirrel-cage IM stator currents, thus assuring a broad range of applications. To monitor the RSH, the STFT employs a sliding window to perform the discrete Fourier transform technique, making it more suitable for online use with noisy and nonstationary signals. Experimental tests demonstrate the effectiveness of the suggested approach.

Maturation and Post-Harvest Resting of Fruits Affect the Macronutrients and Protein Content in Sweet Pepper Seeds.

There are few studies about the influence of fruit maturation and post-harvest resting on seed composition, which can be necessary for seedling development and future establishment. Thus, the objective of this study was to evaluate the effect of maturation and post-harvest resting of fruits on the macronutrient and protein content of sweet pepper seeds. The experimental design was a randomized block, with eight treatments, in a 4 × 2 factorial arrangement. The first factor was fruit maturation stages (35, 50, 65 and 80 days after anthesis), and the second, with and without post-harvest resting of the fruits for 7 days. The characteristics evaluated in seeds were the dry weight of one thousand seeds, macronutrient content, and content of albumin, globulin, prolamin and glutelin proteins. There were reductions in K, Ca and Mg content, and an increase in seed content of albumin, globulin and prolamins as a function of the fruit maturation stage. Post-harvest resting of the fruits provided higher Ca content and protein albumin in seeds. The decreasing order of macronutrients and protein content in seeds, independent of fruit maturation and resting stage of the fruits, was N > K > P > Mg > S > Ca, and albumin > globulin ≈ glutelin > prolamine, respectively.

Nonsexual violence against children and adolescents: a study in a Latin American tertiary and university hospital.

OBJECTIVE: The objective of this study was to assess interpersonal nonsexual violence against children and adolescents in a tertiary university hospital. METHODS: A cross-sectional study was performed in 240 patients under nonsexual violence situation for 15 consecutive years. Data analyses included demographic data, hospital referral site, type and author of nonsexual violence, legal referral, laboratorial and imaging examinations, and outcomes. RESULTS: Nonsexual violence situation was diagnosed in 240 (0.1%) of 295,993 patients for 15 years: 148 (61.7%) in children and 92 (38.3%) in adolescents. Out of 240, the most frequent types of violence were negligence in 156 (65.0%), physical 62 (25.8%), psychological/emotional aggression 52 (21.7%), Munchausen by proxy syndrome 4 (1.7%), and bullying/cyberbullying in 3 (1.3%). Out of 123, the most common pediatric chronic conditions were chronic kidney disease 24 (19.5%), human immunodeficiency virus 14 (11.4%), prematurity 9 (7.3%), cerebral palsy 8 (6.5%), and asthma 8 (6.5%). Further comparison between children versus adolescent under nonsexual violence situation revealed significant difference between the hospital referral sites. The frequency of patients under violence referred from outpatient clinics was significantly reduced in children versus adolescents (27.7 vs. 62%), whereas emergency department was higher in the former group (57.4 vs. 25.0%; p<0.001). All types of violence situations and pediatric chronic conditions were similar in both groups (p>0.05). CONCLUSIONS: Nonsexual violence against our pediatric population was rarely diagnosed in a tertiary hospital, mainly negligence, physical, and psychological/emotional aggression. Approximately two-thirds of violence diagnosis occurred in children, referred mainly by the emergency department. In contrast, approximately one-third of violence diagnosis occurred in adolescents, referred mostly by outpatient clinics.

Doses of sulfur at topdressing and organic compost supply at planting in the production, quality and content of macronutrients in lettuce seeds

The purpose of this study was to evaluate doses of sulfur applied at topdressing, with and without organic compost supply at planting, in the production, physiological quality and content of macronutrients in lettuce seeds. Ten treatments were evaluated in a 5x2 factorial scheme (five sulfur doses at topdressing x with and without application of organic compost at planting). The experimental design was a randomized block design, with four replicates. The sulfur doses applied at topdressing fertilization were 50, 100, 150 and 200 kg ha-1 of S, in addition to the control treatment (dose zero). Regarding the treatments with organic compost, the dose of 70 t ha-1 of compost (wet basis) was supplied at planting. The following characteristics were evaluated: seed production (mass and number of seeds per plant), seed quality (mass of one thousand seeds, first count of the standard germination test, germination percentage, and germination speed index) and content of macronutrients and mineral accumulation. The organic compost supply at planting increased seed production by 43% compared to the treatment without the application of organic compost, while the doses of sulfur did not affect the production of lettuce seeds. The supply of organic compost increased the accumulation of a great part of the macronutrients, except for the accumulation of calcium. The lettuce seeds quality was not affected by both the main treatments, the sulfur doses at topdressing and the organic compost supply at planting. The descending order of nutrients accumulated in the lettuce seeds was nitrogen> potassium> phosphorus> magnesium> calcium> sulfur.

Deinstitutionalization and autonomy: outcomes from a Brazilian mental health policy. / Modos de autonomia em Serviços Residenciais Terapêuticos e sua relação com estratégias de desinstitucionalização.

Therapeutic Residential Services (SRT, in Portuguese) are structures implemented in the context of the Brazilian Psychiatric Reform (BPR), which aims to support psychiatric deinstitutionalization. This paper compares residents of SRTs in two cities in Brazil, analyzing the relationship among the deinstitutionalization strategies and the different types of autonomy they produce. Nineteen individuals from two cities (referred to as Paulo Delgado - PB and Franco Basaglia - FB) participated in this study. Participant observation visits were performed, and five managers and professionals who worked at the psychosocial care networks were interviewed. Narratives were created based on the field diaries and the transcription of the interviews. All the participants raised their degree of autonomy, when compared to the time in which they lived in the psychiatric hospitals. The different ways in which SRTs are organized in both cities produced different manners of exercising autonomy: in PD, home autonomy predominated, while in FB, autonomy in circulating throughout the territory predominated. In both cities, autonomy in managing financial resources was restricted. It was concluded that public policies for deinstitutionalization were effective, although their operationalization could be enhanced.

Participaram 19 indivíduos dos municípios referidos pelos pseudônimos Paulo Delgado (PD) e Franco Basaglia (FB). Foram realizadas visitas para observação participante e entrevistas com cinco gestores e profissionais das redes de atenção psicossocial. Registros em diários de campo e transcrições de entrevistas subsidiaram a construção de narrativas. Todos os participantes ampliaram o grau de autonomia em relação ao período em que saíram das instituições asilares. As formas de organização dos SRTs nos dois municípios produziram diferentes modos de exercer autonomia: em PD predominou a autonomia no habitar, enquanto em FB predominou a autonomia no transitar pelo território. Em ambos, a autonomia na administração de recursos financeiros foi limitada. Consideramos que as políticas públicas para desinstitucionalização foram efetivas, embora sua operacionalização possa ser aprimorada.

Effectiveness of a UVC air disinfection system for the HVAC of an ICU.

Ultraviolet germicidal irradiation (UVGI) uses short-wave ultraviolet (UVC) light to inactivate organisms like viruses, bacteria, and fungi. UVC inactivates a wide range of microorganisms by damaging the structure of nucleic acids and proteins at the molecular level, so they become unable to replicate and cause disease. Thus, UVC can improve indoor air quality by controlling bioaerosols and can be used as an engineering device to interrupt the transmission of pathogenic organisms and potential bioterrorism agents. Recently, the World Health Organization recognized that the COVID-19 virus could be transmitted across large distances, suggesting that indoor ventilation is key in airborne transmission. As a test for the future dissemination of UVC light installations to improve indoor air quality in Hospitals in Sergipe State, Brazil, we made a first installation of UVGI disinfection lamps, strategically placed in the Heating, Ventilating, and Air Conditioning (HVAC) system of the Intensive Care Unit (ICU) at the University Hospital of Lagarto, Federal University of Sergipe, Brazil. Six 15 W low-vapor-pressure mercury lamps emitting 253.7 nm UVGI were installed in the ducts of the fan coil, maximizing their luminous interaction in the air passage. One of the greatest advantages of this type of installation is that the lamps were completely covered, avoiding any risk of hazardous exposure to people and animals. Microbiological tests were carried out to verify the germicidal effect, analyzing the viability of microorganisms circulating in the environment. In this paper, we present our encouraging results, demonstrating the effectiveness of the installation, suggesting that similar devices should be installed in HVAC systems to avoid biological risk to people inside buildings. In addition, we believe that this study may provide useful evidence and guidance for the design of equipment intended to abate the microorganisms that may be used in CBRNE terror attacks.

Ultrastructure of the gill ciliary epithelium of Limnoperna fortunei (Dunker 1857), the invasive golden mussel.

BACKGROUND: Limnoperna fortunei is a freshwater bivalve mollusc originally from southern Asia that invaded South America in the 1990's. Due to its highly efficient water pumping and filtering, and its capacity to form strong adhesions to a variety of substrates by byssus thread, this invasive species has been able to adapt to several environments across South America, causing significant ecological and economic damages. By gaining a deeper understanding of the biological and ecological aspects of L. fortunei we will be able to establish more effective strategies to manage its invasion. The gills of the mollusc are key structures responsible for several biological functions, including respiration and feeding. In this work, we characterized the ultrastructure of L. fortunei gills and its ciliary epithelium using light microscopy, transmission and scanning electron microscopies. This is the first report of the morphology of the epithelial cells and cilia of the gill of L. fortunei visualized in high resolution. RESULTS: The analysis showed highly organized and abundant ciliary structures (lateral cilia, laterofrontal cirri and frontal cilia) on the entire length of the branchial epithelium. Mitochondria, smooth endoplasmic reticulum and glycogen granules were abundantly found in the epithelial cells of the gills, demonstrating the energy-demanding function of these structures. Neutral mucopolysaccharides (low viscosity mucus) were observed on the frontal surface of the gill filaments and acid mucopolysaccharides (high viscosity mucus) were observed to be spread out, mainly on the lateral tract. Spherical vesicles, possibly containing mucus, could also be observed in these cells. These findings demonstrate the importance of the mucociliary processes in particle capture and selection. CONCLUSIONS: Our data suggest that the mechanism used by this mollusc for particle capture and selection could contribute to a better understanding of key aspects of invasion and also in the establishment of more efficient and economically viable strategies of population control.

Objetivo: Avaliar violência interpessoal não sexual contra crianças e adolescentes em um hospital universitário terciário. Métodos: Foi realizado um estudo transversal com 240 pacientes em situação de violência não sexual por 15 anos. A análise incluiu: dados demográficos, local de referência do hospital, tipo e autor da violência, encaminhamento legal, exames laboratoriais e de imagem, e desfechos graves. Resultados: Situações de violência não sexual foram diagnosticadas em 240 de 295.993 (0,1%) pacientes durante os 15 anos do período: 148/240 (61,7%) em crianças e 92/240 (38,3%) em adolescentes. Os tipos de violências mais frequentes foram negligência em 156/240 (65,0%), violência física 62/240 (25,8%), agressão psicológica/emocional 52/240 (21,7%), síndrome de Münchausen por procuração 4/240 (1,7%) e bullying/cyberbullying em 3/240 (1,3%). As condições crônicas pediátricas mais frequentes foram: doença renal crônica 24/123 (19,5%), vírus da imunodeficiência humana 14/123 (11,4%), prematuridade 9/123 (7,3%), paralisia cerebral 8/123 (6,5%) e asma 8/123 (6,5%). Comparações entre crianças e adolescentes em situação de violência não sexual revelaram que houve diferença significativa entre os locais de referência do hospital. A frequência de pacientes sob violência encaminhados de ambulatórios foi significantemente reduzida em crianças versus adolescentes (27,7 vs. 62%), enquanto encaminhamentos de pronto-socorro foram mais numerosos no primeiro grupo (57,4 vs. 25%, p<0,001). Os tipos de violências e condições pediátricas crônicas foram semelhantes nos dois grupos(p>0,05). Conclusões: Violência não sexual na nossa população pediátrica foi raramente diagnosticada em um hospital terciário, principalmente negligência, agressão física e psicológica/emocional. Aproximadamente dois terços dos diagnósticos de violência ocorreram em crianças, preferencialmente encaminhadas pelo departamento de emergência. Em contrapartida, cerca de um terço dos diagnósticos de violência ocorreu em adolescentes, encaminhados principalmente pelos ambulatórios.

Medos, desejos e preocupações acerca da sindemia de Covid-19 e sofrimento psíquico: experiências extensionistas no sul da Bahia, Brasil / Fears, desires and concerns surrounding the Covid-19 syndemic and psychic suffering: university outreach experiences in the south of Bahia, Brazil / Miedos, deseos y preocupaciones sobre la sindemia de Covid-19 y sufrimiento psíquico: experiencias extensionistas en el sur de Bahia, Brasil

Este artigo analisa as relações entre políticas públicas de enfrentamento da Covid-19, desinformação da população e sofrimento psíquico por meio da integração de resultados de duas experiências extensionistas ocorridas no mesmo território e mesmo período de tempo: "Tira dúvidas sobre a Covid" (TDC), programa de rádio que respondia a perguntas dos ouvintes; e "Plantão Psicológico On-line" (PPO), que tem oferecido atendimento emergencial durante a pandemia. Foi realizada análise qualiquantitativa de perguntas direcionadas por ouvintes ao quadro radiofônico e de preocupações sobre a pandemia manifestadas por usuários do PPO no formulário de inscrição para o atendimento. Concluiu-se que a desinformação agravou o contexto de crise, não apenas ampliando as infecções e os óbitos, mas elevando também o sofrimento psíquico. A propagação de notícias falsas e o aumento de problemas de Saúde Mental durante a pandemia são, pois, faces do mesmo fenômeno complexo.(AU)

This article analyzes the relationship between Covid-19 response policies, disinformation and psychic suffering drawing on the results of two university outreach experiences conducted in the same region during the same period: "Answering Questions about Covid" (TDC), a radio program answering listeners queries; and the "On-line Counselling Service" (PPO), offering emergency therapy during the pandemic. We performed a quali-quantitative analysis of listeners' questions and concerns about the pandemic raised by PPO users on the counselling application form. It is concluded that disinformation aggravated the context of the crisis, leading to a rise in infections, deaths and psychic suffering. The spread of fake news and increase in mental health problems are therefore facets of the same complex phenomenon.(AU)

Se realizó un análisis cuali- cuantitativo de preguntas dirigidas por oyentes al programa de radio y de preocupaciones sobre la pandemia manifestadas por usuarios del PPO en el formulario de inscripción para la atención. Se concluyó que la desinformación agravó el contexto de crisis, no solo ampliando las infecciones y los fallecimientos, sino aumentando también el sufrimiento psíquico. La propagación de noticias falsas y el aumento de problemas de salud mental durante la pandemia son, por lo tanto, caras del mismo fenómeno complejo.(AU)

24 h movement behavior and metabolic syndrome study protocol: A prospective cohort study on lifestyle and risk of developing metabolic syndrome in undergraduate students from low-income regions during a pandemic.

Introduction: Obesity and its comorbidities are increasingly prevalent in Latin America, with a more rapid growth in individuals with lower income. The composition of movement behaviors within a 24 h period may have important implications for obesity, metabolic and mental health in cross-sectional data. However, a longitudinal study is needed to confirm the findings from the primarily cross-sectional evidence. The COVID-19 pandemic has been associated with cardiometabolic outcomes and has impeded healthy behavior. Objectives: The first objective is to evaluate the time elapsed since the diagnosis of not meeting 24 h movement guidelines and the potential subsequent onset of metabolic syndrome in undergraduate students from low-income regions within 4 years of follow up. The second objective is to test the association between 24 h movement, mental wellbeing, eating behaviors, and abdominal obesity in the period of this pandemic. Methods: The 24 h movement behavior and metabolic syndrome (24 h-MESYN) study is a multicentre cohort study that will include participants from two Brazilian cities within the 2022-2025 period to asses the first objective, and also a nested case-control study at the baseline will be carried out to evaluate the second objective. Previously, we conducted a feasibility study in the academic year of 2021 to assessing the psychometric properties of subjective tools, refine our study protocol, and adjust the epidemiological conditions of the cohort's subsequent phases (like as prevalence of exposure of interest, sampling process, and study adherence). Statistical tests as Cohen's kappa agreement; factorial analysis; logistic, Poisson and linear regression; and Kaplan-Meier analysis will be performed, in accordance with the objectives.
