This study was carried out to identify the spatial distribution and characterize the clinical–epidemiological profile of Visceral Leishmaniasis (VL) in Maranhão state, Brazil, from 2009 to 2020. This descriptive ecological study collected sociodemographic and clinical data of VL cases from the Brazilian Notifiable Diseases Information System database. A spatial autocorrelation analysis (Moran statistics) was performed. From 2009 to 2020, 5699 cases of VL were reported, with incidence of 6.5 cases/100,000 and prevalence of 7.1 cases/100,000. The temporal analysis showed a significant growth in incidence from 2009 to 2018, followed by a significant decrease between 2019 and 2020. The Moran map shows hotspots of high values in the central–west and central–east regions, and hotspots of low values in the northern region of Maranhão. The profile of patients affected by VL comprises males (OR = 1.8; IC95% = 1.72–1.92), aged under 14 years, brown, and with incomplete elementary schooling. The main symptoms reported were fever, fatigue, and edema. The main diagnostic method was laboratory. The mortality rate was 6.8%, and co-infection with HIV was reported by 8.5% of patients. The results of this study indicated the increase in incidence and lethality, as well as the expansion, of leishmaniasis in the state of Maranhão.

Antimicrobial resistance (AMR) is a public health concern in Uganda. We sought to conduct an extended profiling of AMR burden at selected Ugandan tertiary hospitals. We analyzed routine surveillance data collected between October 2020 and March 2023 from 10 tertiary hospitals. The analysis was stratified according to the hospital unit, age, gender, specimen type, and time. Up to 2754 isolates were recovered, primarily from pus: 1443 (52.4%); urine: 1035 (37.6%); and blood: 245 (8.9%). Most pathogens were Staphylococcus aureus, 1020 (37%), Escherichia coli, 808 (29.3%), and Klebsiella spp., 200 (7.3%). Only 28% of Escherichia coli and 42% of the other Enterobacterales were susceptible to ceftriaxone, while only 44% of Staphylococcus aureus were susceptible to methicillin (56% were MRSA). Enterococcus spp. susceptibility to vancomycin was 72%. The 5–24-year-old had 8% lower ampicillin susceptibility than the >65-year-old, while the 25–44-year-old had 8% lower ciprofloxacin susceptibility than the >65-year-old. The 0–4-year-old had 8% higher ciprofloxacin susceptibility. Only erythromycin susceptibility varied by sex, being higher in males. Escherichia coli ciprofloxacin susceptibility in blood (57%) was higher than in urine (39%) or pus (28%), as was ceftriaxone susceptibility in blood (44%) versus urine (34%) or pus (14%). Klebsiella spp. susceptibility to ciprofloxacin and meropenem decreased by 55% and 47%, respectively, during the evaluation period. During the same period, Escherichia coli ciprofloxacin susceptibility decreased by 40%, while Staphylococcus aureus gentamicin susceptibility decreased by 37%. Resistance was high across the Access and Watch antibiotic categories, varying with time, age, sex, specimen type, and hospital unit. Effective antimicrobial stewardship targeted at the critical AMR drivers is urgently needed.

Authors: De Lima Luan Filipe Salvador , Paterniani Maria Elisa Ayres Guidetti Zagatto , Gallo Paulo Boller , Fachini Cristina , Bernini Cristiani Santos
Published: April 2024

O milho consumido in natura (Milho verde) é uma tradição em todo o país e se apresenta como um importante nicho de mercado e fonte alternativa de renda para os produtores. Contudo, a escassez de genótipos que reúnam características de produção e qualidade é um obstáculo na exploração dessa atividade.  Neste sentido, o desenvolvimento de cultivares que atendam às expectativas do produtor e consumidor depende do sucesso dos programas de melhoramento de híbridos de milho verde. Os métodos de dialelos ou top crosses são amplamente utilizados para a seleção de linhagens e obtenção de híbridos em programas de melhoramento de milho. Desta forma, o objetivo desse trabalho foi avaliar híbridos, estimar a capacidade geral de combinação (CGC) entre linhagens de milho com aptidão para o consumo in natura e identificar combinações híbridas promissoras, que ofereçam elevada produtividade e qualidade, beneficiando produtores e consumidores. Para a obtenção de híbridos top crosses foram cruzadas doze linhagens S6, pertencentes ao programa de melhoramento de milho verde do Instituto Agronômico (IAC) em Campinas, com os testadores IAC 8046 e Cativerde. Os 24 híbridos topcrosses e mais seis testemunhas comerciais foram submetidos a avaliações de campo, no Polo Regional da APTA (IAC) em Mococa-SP, no ano agrícola 2019/20.   Nesse local, a temperatura e umidade média foram 24,84ºC e 69,21%, respectivamente. Ainda, segundo o CIIAGRO (2021), a precipitação no período de florescimento foi de 880,912mm, com chuvas e ventos fortes que se apresentaram como adversidades na condução do experimento. Avaliaram-se os seguintes caracteres morfoagronômicos: florescimento masculino e feminino (número de dias), peso de espigas (kg.ha-1), diâmetro e comprimento da espiga (cm) e peso de 100 grãos (g). Foi possível verificar diferenças significativas entre os tratamentos para peso de espigas, número de fileiras de grãos na espiga, florescimento masculino e peso de 100 grãos.  Houve efeitos significativos da CEC (dominância) para os caracteres florescimento masculino, peso de espigas e da  CGC para todas as características avaliadas, evidenciando os efeitos aditivos. Os híbridos top crosses Cativerde x (6B277V-4-3) e (6B277V-2-4) x IAC-8046 foram selecionados por apresentarem as melhores médias de produtividade, estimativas elevadas da capacidade geral e específica de combinação das linhagens envolvidas, evidenciando ainda a sua tolerância a fatores de estresse hídrico.

Published: April 2024

Relevance. Type 1 diabetes mellitus is a prevalent chronic metabolic autoimmune condition among children and adolescents. The compromised metabolic control associated with this endocrinopathy elevates the risk of various complications, including oral diseases. Establishing an interdisciplinary approach to enhance oral care for young patients with type 1 diabetes mellitus is crucial in contemporary dentistry.

Objective. To synthesize information regarding the relationship between type 1 diabetes mellitus and oral health in children and adolescents.

Materials and methods. The search strategy involved both electronic and manual searches, querying key databases like PubMed, eLibrary, MEDLINE, and Embase using specific keywords related to the subject. Additionally, a manual search was conducted in the references of relevant articles.

Results. The literature review identified the most frequently occurring oral diseases in children and adolescents with type 1 diabetes mellitus. It highlighted key biomarkers for monitoring oral health in these patients. The review uncovered major gaps in understanding the oral manifestations of type 1 diabetes mellitus.

Conclusion. Exploring the links between pathogenesis of type 1 diabetes mellitus in young populations and their oral health is pivotal for pediatric dentistry and endocrinology. Addressing this issue could lead to more effective treatment strategies, enhance preventive measures, and improve the diagnostic accuracy of oral diseases. Discrepancies among study findings underscores the imperative for ongoing research and substantiates the value of an interdisciplinary approach in investigating the dental manifestations associated with this endocrine disorder.
Factors for the integration of prevention in primary care: an overview of reviews
Authors: Clet Estelle , Leblanc Pierre , Alla François , Cohidon Christine
Published: April 2024

Background

The global burden of non-communicable diseases is increasing and the need for prevention is huge. Policies have yet to produce results and prevention indicators remain low. Primary care (PC) represents an opportunity to optimise the practice of prevention, but GPs are coming up against barriers that are holding back their prevention practices.

Aim

To identify the barriers and facilitators for the implementation of routine prevention practices in PC.

Design & setting

This study is an international overview of reviews focusing on the integration of prevention in PC settings.

Method

The search was conducted in July 2022 using MEDLINE, Embase, Web of Science, and the Cochrane Database of Systematic Reviews. Included reviews are systematic reviews or scoping reviews adopting a systematic approach.

Results

The 35 reviews included identify multiple barriers and facilitators related to the integration of prevention in PC. These factors are heterogeneous with regard to their source (the patient, the professional, and the health system) and their level of action (individual, organisational, or contextual). The results show the need to organise PC at the professional level (for example, in training), at the local level (for example, the information system), and at the political level (for example, the unclear definition of the role of professionals).

Conclusion

The factors influencing the integration of prevention in PC are multiple and act at different levels (individual, organisational, and health-system level). Organisation factors play a major role and seem to be a means of overcoming the difficulties encountered by healthcare professionals in developing preventive practices.

Environmental function of business: content and role in modern economy
Authors: Nenastyev N. A. , Yashalova N. N.
Published: April 2024

The environmental aspect of business activities is considered in the vast majority of cases as an element of corporate social responsibility or as part of the social function of enterprises. Within the framework of this study, the goal was set to justify the feasibility of identifying the actual environmental function of business and to reveal its role and content. Such a step will allow, if necessary, to analyze it in isolation from the general social vector of development of private enterprises based on a separate concept. To achieve the goal, four tasks were consistently solved. Firstly, the essence and importance of the “green” transition within national economies is revealed. Secondly, evidence is provided of the priority of the process of greening business structures in comparison with other vectors of growth of the Russian “green” economy. Thirdly, the main provisions of the theory of environmentally oriented business are formulated on the basis of the concept of corporate social responsibility. Fourthly, the concept and components of the “green” function of business at the present stage are revealed.

Influence of organizational factor on change productivity and work intensity (based on the example of US economy sectors)
Authors: Minat V. N.
Published: April 2024

Based on the results of existing research and the empirical data obtained by the author, a number of conclusions have been made about the nature and degree of influence of the labor organization factor (labor force, actually living labor) on productivity and labor intensity in industries/sectors of the US economy. This analysis covers the period from 2010 to 2022, when the American economy, subject to an extremely high degree of servization, entered the stage of “re-industrial turn”, formed on the basis of a new sixth technological structure, characterized, in addition to technological innovations, by a significant increase in the role of a person - a qualified worker with creative content of work. Based on the results of regression analysis, the grouping of industries/sectors of the US economy according to the elasticity of productivity and intensity depending on the indicators of labor organization in American companies, expressed through the corresponding regression coefficients, allowed us to draw conclusions about the ambiguity in the nature and significance of the influence of the sought factor on the explained variables. Currently, a number of American industries are forced to use extensive forms of labor organization, in particular to increase the actual hours worked, in order to maintain profitability and competitiveness, despite increasing social costs. The identification of four groups of sectors of the American economy according to this criterion indicates a change in the structural policy of the United States, characterized by a sectoral focus in the field of stabilization and increasing productivity growth rates due to the organizational factor.

Authors: Ganehenege Manawadevi Yasatissa Udugala , Shifana Mohamed Haniffa
Published: April 2024

Schools and Universities in Sri Lanka have been closed intermittently during the past three years due to COVID-19 and fuel shortages. During this period, in-person teaching became impossible, and online teaching was developed. However, schools have been reopened for in-person teaching and learning at present. In contrast, other countries adopted both methods, online and in-person. It was noticed that a decline in test scores among junior secondary students in some education zones during online learning. This study aimed to assess and compare the effectiveness of online and in-person teaching and learning science among junior secondary students in a selected school within the Kurunegala education zone. The study objectives were to 1). conduct both online and in-person science lessons for two groups separately and compare grade-eight students' performance in both settings; 2) compare teacher-student interaction, learning resources, peer group interaction, and motivation in both sittings; and 3) make suggestions for effective teaching and learning process. Two equally weighted courses were used to teach the two groups. Convenience sample of 72 Grade 8 students was used in the data collection with mixed methods approach. Pre-tests, post-tests, and questionnaires were used in the quantitative data collection. Qualitative data were collected via interviews with ten randomly selected students. The findings revealed that the performance scores of in-person group in Unit 4 (Properties of Matter) of grade-eight Science evaluation were slightly higher  than that of online group. Both groups demonstrated similar performance levels in Unit 8 (Changes in Matter). However, in-person teaching exhibited significantly higher scores (p < 0.05) than the online group for factors such as teacher-student interaction, peer group interaction, learning resources, and motivation. Students achieved high results in both settings but needed more resources, reliable internet facilities, and adequate technology skills for online teaching and learning. The study suggests adapting effective instructional methods, technology usage, resource availability, training, participation, peer interactions, and monitoring well-being for effective online science teaching.

Published: April 2024

Water transport plays an essential role in economic progress and regional cohesion, especially in the vast Northern region of Brazil, characterized by extensive territorial extensions and the presence of imposing rivers, such as the Amazon. This form of transport is a strategic route for the movement of goods and passengers, connecting remote regions and contributing to logistical efficiency. Due to the lack of land infrastructure in certain areas, rivers become crucial routes for commerce, facilitating access to isolated communities and stimulating economic exchanges. To this end, the present study aims to analyze strategies to optimize waterway traffic management in the North of Brazil, aiming to reconcile economic development with environmental preservation and the well-being of riverside communities. The justification for this research lies in the strategic importance of waterway traffic in this region, marked by a vast territorial extension and imposing rivers such as the Amazon. The complexity of the Amazonian scenario, combined with the scarcity of in-depth studies on the topic, highlights the need for a balanced approach that promotes economic development without compromising river ecosystems and the quality of life of local populations. The methodology adopted combines extensive bibliographical research and qualitative data analysis, exploring academic sources and conducting interviews with relevant stakeholders. This study seeks to fill gaps in existing knowledge, contributing to support public policies and sustainable practices in the management of waterway traffic in the Northern region of Brazil.

Evaluation of the adsorption capacity of glyphosate in a microbial cellulose
composite
Authors: Trejo-Espinosa María de Jesus
Published: April 2024

The objective of this project was to develop a composite based
on microbial cellulose (CM), chitosan (Qs) and citric acid (AC)
as a crosslinker at two different concentrations (4 and 6% w/v).
The CM was obtained from the fermentation of fruit residues
with a SCOBY (symbiotic consortium of bacteria and yeast). The
composites were morphologically characterized by SEM and
spectroscopy techniques (FTIR-ATR) as well as UV-VIS
spectrophotometry with ninhydrin were used to evaluate the
composite as an adsorbent for glyphosate in water; in the spectra
obtained by FTIR, the representative vibrational bands of the
functional groups belonging to chitosan and microbial cellulose
were observed; for cellulose and chitosan composites with 4%
citric acid in 1579 cm-1
, 1386 cm-1
, 1046 cm-1
and 853 cm-1
; and
for the 6% cellulose-chitosan-citric acid composite at 1573 cm-1
,
1380 cm-1
, 1056 cm-1
and 503 cm-1
, thus attributing cross linkage
between the biopolymers. Post- adsorption FTIR-ATR analysis
revealed significant changes possibly attributable to the
adsorption of glyphosate in the cellulose composites. Further
research is still being conducted to better understand this
interaction and the involved mechanism; the goal is to
comprehend how microbial cellulose can effectively adsorb
glyphosate, which could have practical and efficient applications
in the remediation of environments contaminated with this
herbicide.

supercapacitor
Authors: Garza-González Williams
Published: April 2024

This article presents the analysis and design of a new
converter that combines the current doubler topology and
the parallel converter to achieve greater stability and
effective reduction of ripple in both voltage and current
parameters. Basically, the DC-DC (Direct Current to
Direct Current) converter operates with pulse modulators
to control the current in the desired charging or
discharging direction. Extensive simulations were carried
out at nominal values of 48 V and 8.5 A of output, and 100
V of input to confirm the performance of this converter.
The approach used has benefits in terms of safety, reduced
electrical noise, practical implementation for

Polyvinyl alcohol and fluorescein electrospun fibers
Authors: Cuahuizo-Huitzil Guadalupe
Published: April 2024

Electrospinning is a technique that allows obtaining
new fibrous structures from synthetic or natural
polymers for the development of materials used in
the pharmaceutical and biomedical industries,
among others. However, the low production rate of
electrospinning has limited its industrial application,
forcing the development of new injectors that allow
higher productivity. In this work, a coaxial injector
was designed to develop products encapsulated in
polymeric fibers. For the demonstration of the
encapsulation of one fiber included in another,
fluorescein was used as internal compound in a
polyvinyl alcohol solution, and polyvinyl alcohol
was used as external fiber. It was obtained that the
encapsulation process is possible by using this
coaxial injector.

Design and construction of a solar simulator for characterization of photovoltaic modules
Authors: López-Carrillo José Luis
Published: April 2024

This work comprises the design, development,
characterization and implementation of a solar simulator
prototype for photovoltaic modules, implementing LED
lamp technology as artificial lighting. First, we designed
the prototype in AutoCAD, and then we built it using a box
(100×100×35cm) made of sheet metal as a cabin. We used
a super polished sheet as a reflective surface inside the
cabin. Inside the cabin, we placed 8 LED lamps of 200 and
50 Watts in order to have a constant irradiance. An
Arduino UNO board and a SPLITE2 pyranometer were
used to measure lamp irradiance, along with a MATLAB
data acquisition system. As a result, a functional prototype
of a CB type solar simulator with an area of 1m2 was got
with a constant irradiance of 200 W/m2
at a height of 30cm
and with a homogeneity of 98.6 W/m2 difference between
peaks.
Design considerations for the dimensioning of parabolic trough solar thermal plants
Authors: Lizárraga-Morazán Juan Ramón
Published: April 2024

Solar heaters of the parabolic trough type, PTC, are a
proved technology that has a wide diversity of industrial
applications. The prediction of the thermal conditions in
these devices plays a fundamental role in the development
and design of thermal plants capable of meeting the heat
load requirements. To this end highly complex thermal
models have been derived which are difficult to solve and
implement. This work puts forward a PTC transient
thermal model which was validated using experimental
data and compared against other theoretical models
existing in the open literature. Along with this model, a
novel sequential solution procedure is proposed with
which a better follow up of variable outputs is obtained. A
parametric analysis was carried out of for the main design
variables using the Present Value of the Life Cycle Energy
Savings (PVLCES) and Total Integrated Heat (TIH) using
daily typical data in the winter and summer seasons for the
city of Guanajuato. Due to its transient nature, the model
can be implemented in research where optimisation tools
are required such as Deep Learning, Machine Learning
and Control, which are basic in the dimensioning of
thermal solar plants.

Authors: González-Sosa Jesús Vicente
Published: April 2024

Nowadays, additive manufacturing (MA) and
computational simulation are essential in the
technological development for the validation of
materials, thus assimilating the requirements and
properties of a material before being used for specific
applications, so in this work the characterization of the
specimen for tensile tests is carried out, which is made
in ABS material, using additive manufacturing through
3D printing and then FEM (Finite Element Method) is
applied, in order to obtain a database regarding the
physical properties of the material when subjected to a
simulation that represents the tensile test in plastic
materials. This seeks to implement new areas of
development that involve innovation in the
characterization of materials used in additive
manufacturing, increasing the use of computational
tools with engineering simulators. The use of the data
will be available to the academic and research
community in order to enrich FEM applications.
