Chagas disease, caused by the parasite Trypanosoma cruzi, is a public health issue in non-endemic nations due to its various modes of transmission. Despite control and surveillance efforts, it remains a significant public problem associated with diverse factors. Hence, the present study aimed to analyze the knowledge, attitudes, and practices regarding Chagas disease in a rural Ecuadorian population. It was an observational, descriptive, prospective cross-sectional investigation with a quantitative approach, employing surveys as the technique and a questionnaire divided into four sections: socioepidemiological factors, knowledge, attitudes, and practices. These sections allowed for evaluation across four levels: optimal, good, regular, and poor. The study reveals limited awareness of Chagas disease, with a widespread lack of familiarity regarding its transmission, symptoms, and treatment. Although most individuals identify the insect associated with the disease, there is a low incidence of it and varying willingness to participate in vector control activities. Additionally, a significant connection between knowledge levels and attitudes and practices toward the disease is evident. In conclusion, it is crucial to implement educational and awareness programs tailored to the diverse needs of the population to promote effective prevention and control of Chagas disease in rural Ecuadorian communities.

Background: The growing interest in organic-inorganic compounds is motivated by the unique advantages these materials offer. Combining organic and inorganic elements enables the creation of structures with varied geometries, paving the way for a wide range of coordination possibilities and directed self-assembly. Aims: To synthesize and characterize by spectroscopic techniques and thermal analysis new Co+² compounds coordinated with 4-aminopyridine; 2,2'-bipyridine and evaluate their bactericidal potential against two distinct bacterial strains: Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). Method: In this study, we report the synthesis route and characterization of the complexes by FTIRmed spectroscopy and TG/DSC thermal analysis, and the obtained complexes have the stoichiometry [Co(NH3)4(bipy)]Cl3.½H2O and [Co(NH3)4(4-apy)] Cl3.½ H2O. Results: The synthesis methodology of cobalt complexes with the ligands 4-aminopyridine and 2,2'-bipyridine proved effective, resulting in the formation of desired precipitates. The thermogravimetric analysis provided insights into the thermal properties of the complexes, indicating stability within certain temperature ranges. Mid-infrared spectroscopy allowed for the structural characterization of the complexes, highlighting characteristic shifts in the bonds of the coordinated ligands. Discussions: Evaluation of the bactericidal activity of the complexes yielded promising results, underscoring the importance of compound solubility. The complex [Co(NH3)4(bipy)]Cl.½H2O exhibited efficacy in bactericidal inhibition, particularly against the S. aureus strain. These findings emphasize the relevance of solubility and chemical composition in the antimicrobial activity of the complexes. Furthermore, the results contribute to the advancement of coordination chemistry and its potential applications, particularly in pharmacology. Conclusions: These biological activity tests revealed significant activity of the complexes against both bacterial strains. This suggests that these complexes have the potential to inhibit the growth and proliferation of these bacteria, indicating their usefulness as effective antimicrobial agents. [ABSTRACT FROM AUTHOR]

Objective: To identify and characterize animation videos on health education related to elimination ostomies. Method: Study of quantitative nature of the descriptive type with a stage of technological prospection in the literature and on the Youtube video sharing platform. Results: The study did not identify articles in the literature; however, 19 videos were identified on YouTube, of which the most discussed topics were: the making and definition of colostomy, definition and manufacture of ileostomy, preparation of urostomy and causes of manufacture of elimination ostomies. Most of the animations found on the platform were in English and none in Portuguese, revealing the scarcity of this material for people with elimination stomas in Brazil. Conclusion and implications for practice: The study was limited to the identification and characterization of the available videos, partially reaching the objective, thus, emphasizing the need for other studies that address this issue so that it can support the construction and validation of an animation video on elimination stomas based on scientific evidence, so that it is used as a tool for health education.

Antifeedant and contact repellent activity of thyme, tarragon, marigold and lavender crude extracts against the insect pest Epicauta atomaria Germar, 1821 (Coleoptera: Meloidae) was evaluated. The extracts were obtained by sequential maceration with dichloromethane, ethyl acetate and methanol. The antifeedant and contact repellent activity was evaluated by means of the feeding index and repellency percentage respectively. The results obtained indicate that the tarragon dichloromethane, ethyl acetate, and methanol extracts, lavender methanol extract and marigold and thyme ethyl acetate extracts, had a strong antifeedant activity against E. atomaria, both with median AI values of 100 %. On the other hand, only the lavender dichloromethane extract had a moderate repellent activity against E. atomaria, at all the exposure times evaluated, with median repellency percentage values of 60 %, 80 % and 50 % at 15, 30 and 60 minutes of exposure, respectively.

Dry forests in Ecuador are highly valued diverse ecosystems, but under pressure from anthropogenic activities that alter their composition, structure, and dynamics. The objective of this work was to analyze the structure and abiotic conditions of the tropical dry forest of the La Pila Vieja sector in the Sancán Valley, Manabí, Ecuador. The diameter and height of individuals greater than 5 cm were recorded in plots of 0.10 ha validated by the area-species curve; The value indices of ecological importance, Simpson, Shannon, and diametric structure were calculated. 336 individuals belonging to 31 species within 28 genera and 15 families were recorded. The families with the highest number of species were: Fabaceae, Boraginaceae, Rutaceae, Moraceae and Sapindaceae. The most ecologically important species detected: Ceiba trichistandra, Bursera graveolens, Leucaena trichoides and Mauria heterophylla. According to the Shannon index, the diversity was high (3.72). The abiotic variables related to the abundance of species explained the spatial arrangement satisfactorily and explained 97,40% of the species-abiotic variable relationship. The species found are representative of the tropical dry forest with anthropogenic intervention of selective use and without technical planning, influenced by abiotic variables such as: organic matter, pH and potassium, which condition their distribution.

If there is one thing we can be sure about the COVID-19 pandemic, it is that it caused an irruption of such magnitude throughout the world that the resonances of the multiple and varied changes it generated have yet to be seen. In relation to communication processes, the demand for information in real time increased and the media took center stage, especially in an initial period when the possibilities of intersubjective contrasts between people were diminished by the confinements. But this was not a constant: as the pandemic spread over time, it lost its novelty character and went from center stage to backdrop in media coverage. This research describes the thematic shifts and the predominant frames that La Nación, Clarín (in its digital versions) and Infobae deployed in their coverage of the pandemic between 2020 and 2022. Framed in the contributions of the agenda setting and framing theories, this paper starts with a quantitative content analysis and compares four specific time frames (April 2020, October 2020, May 2021 and January 2022), chosen for having represented significant peaks in the development of the pandemic in national health terms. The analysis shows that the concentration of the health issue, as well as the prominence of the variables that make up the morality and human interest frames were diluted over time, making the frames in the coverage of the issue less compact and more dispersed.

The largest Kamari ista (banquet or festival of abundance) in the entire Kichwa-speaking Amazon is celebrated in the community and rural parish of Canelos, in the Pastaza district in the province of the same name, in Ecuador. Based on a request from the same community for the Kamari to be registered and certified as national heritage, between 2013 and 2022 participatory ethnographic work was carried out to prepare the base document for said goal. In this process, it became evident that, beyond certain ethnographic works from several decades ago, little is known today about this festival or ritual, its function and meaning. Starting from the work carried out within the framework of heritage certification, the objective of this article is to analyse the Kamari of Canelos from an anthropological perspective: its complex process of preparation and development, its intercultural origin, and especially its social function and cultural meaning.

The advent of the 1988 Federal Constitution and subsequent regulation of articles 182 and 183 significantly impacted Brazilian urban planning, introducing democratic urban management as the prerogative of municipalities. Focusing on popular participation in urban and regional planning processes, this study presents a qualitative approach and employs systematic review techniques to select the academic production of theses published between 2001 and 2022, in the National Base of Theses and Dissertations (BNDT). The main objective is to analyze the main conflicts and opportunities found through popular participation in democratic urban planning processes, with an emphasis on the Master Plan. Based on the descriptors “urban planning or master plan” and “social participation or democracy”, 21 theses were selected from the 64 found, as they gave prominence to the theme and presented empirical cases. The result is the diagnosis of the main challenges and opportunities found in different cities in the democratic processes of urban planning. It is possible to see that the obstacles are repeated and indicate a technical and centralizing pattern of the public entity, conflicts of interests between the different actors (state, municipal councils, businesspeople, popular movements, society), lack of knowledge of local dynamics and resistance to popular participation (hampered by lack of technical knowledge, opaque information and scarce opportunities). On the other hand, municipalities more prone to systemic openness signaled that experience based on learning, sharing of power and information are important points for achieving popular participation.

This work addresses the fundamental concepts in the design of a voice communications system that uses the operating principles of direct current power line communications (DC-PLC: Direct Current - Power Line Communications) based on BFSK modulation. The system is composed of a transmission subsystem and a voice signal reception subsystem, these elements are interconnected through a DC-PLC channel referenced to a twisted copper pair. The transmission subsystem performs the functions associated with the conditioning, digitization and processing of the signal for its digital transfer with a BFSK modulation in the communication channel. The receiving subsystem performs the BFSK demodulation, processing and recovery of the voice signal for monitoring. For both subsystems a design based on the use of Silicon Laboratories 8051 core microcontrollers is proposed. The UART peripheral available in the 8051 microcontrollers is used for digital data transfer and is applicable as a transmission method in the DC-PLC channel type. In addition, the design criteria of the internal circuits are presented and exposed through their electrical schematics. [ABSTRACT FROM AUTHOR]
